GU LF PORT

Gulfport  Energy  Corporation  is  an  Oklahoma  City-based 
independent  oil  and  natural  gas  exploration  and  production 
company  with  its  principal  producing  properties  located 
along  the  Louisiana  Gulf  Coast  and  in  the  Permian  Basin  in 
West  Texas.  Gulfport  recently  acquired  an  acreage  position 
in the Niobrara Formation of Western Colorado. Gulfport also 
holds a sizeable acreage position in the Alberta Oil Sands in 
Canada through its interest in Grizzly Oil Sands ULC. 

OPERATIONAL AREAS

PERMIAN BASIN

Year End ’10 Leasehold Position: 
14,723 Net Acres

The Permian Basin area covers a significant portion 
of western Texas and eastern New Mexico and is 
considered one of the major producing basins in 
the United States. The Wolfcamp/Spraberry play, 
referred  to  as  Wolfberry,  of  the  Midland  Basin 
lies in the area where the historically productive 
Spraberry  trend  geographically  overlaps  the 
productive  area  of  the  emerging  Wolfcamp 
carbonate  play.  The  Wolfcamp  is  characterized 
by  an  approximately  2,000  feet  section  of 
organic  rich  basin  floor  debris  flows  shed  from 
the  Central  Basin  Platform.  In  2010,  25  gross 
(11  net)  wells  were  drilled  on  Gulfport’s  Permian 
acreage. Gulfport has identified 226 gross future 
development drilling locations.

HACKBERRY

The Hackberry field in Louisiana is located along 
the western shore and the land surrounding Lake 
Calcasieu, 15 miles inland from the Gulf of Mexico. 
The  Hackberry  field  is  a  major  salt  intrusive 
feature, elliptical in shape as opposed to a classic 
“dome,” divided into east and west field entities by 
a saddle. There are over 30 pay zones at this field. 
During 2005, Gulfport completed a proprietary 42 
square mile 3-D seismic survey at East Hackberry, 
the  first  modern  seismic  program  undertaken  at 
this field. Gulfport believes that this 3-D seismic 
data  enhances  its  probability  of  drilling  success, 
and  continues  to  evaluate  the  3-D  seismic  data 
to  identify  additional  drilling  locations.  Gulfport 
has also licensed approximately 54 square miles 
of  3-D  seismic  data  covering  a  portion  of  the 
area and are reprocessing the data. During 2010 
at Hackberry, we recompleted ten gross and net 
wells and drilled six gross and net land wells and 
two gross and net wells on water. All of the eight 
wells  drilled  during  2010  were  completed  as 
producing wells.  

WEST COTE BLANCHE BAY

Year End ’10 Leasehold Position:
5,668 Net Acres

Year End ’10 Proved Reserves:
4.52 MMBOE

Year End ’10 Probable Reserves:
6.15 MMBOE

2010 Production:
3,408 BOEPD

The  West  Cote  Blanche  Bay  (“WCBB”)  field  is 
located  approximately  five  miles  off  the  coast 
of  Louisiana  in  a  shallow  bay  with  water  depths 
averaging eight to ten feet.  WCBB overlies one of 
the largest salt dome structures on the Gulf Coast. 
The  field  is  characterized  by  a  piercement  salt 
dome,  which  created  traps  from  the  Pleistocene 
through  the  Miocene  formations.  The  relative 
movements  affected  deposition  and  created  a 
complex  system  of  fault  traps.  In  2010,  Gulfport 
recompleted  72  gross  and  net  wells  and  drilled 
23 gross and net wells at WCBB. All 23 new wells 
were completed as producers. 

CANADIAN OIL SANDS

Year End ’10 Proved
+ Probable Reserves:

Year End ’10 Leasehold Position:
133,407

During  the  third  quarter  of  2006,  Gulfport, 
through  its  wholly-owned  subsidiary  Grizzly 
Holdings 
interest 
Inc.,  purchased  a  24.9% 
in  Grizzly  Oil  Sands  ULC  (“Grizzly”).  During 
2006  and  2007,  Grizzly  acquired  leases  in 
the  Athabasca  region  located  in  the  Alberta 
Province near Fort McMurray within a few miles 
from  other  existing  oil  sands  projects.  Grizzly 
has  approximately  534,000  acres  under  lease 
and  Gulfport’s  total  net  investment  in  Grizzly 
was  approximately  $46.5  million,  including  a 
note receivable of $20.0 million, at December 31, 
2010. To date, Grizzly has drilled an aggregate of 
199 core holes and three water supply test wells, tested nine separate lease blocks and 
conducted  a  seismic  program.    During  the  2010/2011  drilling  season,  Grizzly  will  have 
drilled 32 locations at Thickwood Hills, 14 locations at Firebag River, 17 locations at Algar 
Lake, and eight total locations at Athabasca Rapids and Horse River. 

Year End ’10 Recoverable
Resource:
513 MMBO

In March 2010, Grizzly filed an application in Alberta, Canada for the development of an 11,300 barrel per day SAGD 
facility at Algar Lake. Grizzly expects regulatory approval by mid-2011, followed by an anticipated construction period 
of 18 months leading to first production.

During  2005,  Gulfport  purchased  a  23.5% 
ownership  interest  in  Tatex  Thailand  II,  LLC,  or 
Tatex, at a cost of $2.4 million. Tatex, a privately 
held  entity,  holds  85,122  of  the  1,000,000 
outstanding shares of APICO, LLC, or APICO, an 
international  oil  and  gas  exploration  company. 
APICO  has  a  reserve  base  located  in  Southeast 
its  ownership  of  concessions 
Asia  through 

covering approximately two million acres which includes the Phu Horm Field.

During  the  first  quarter  of  2008,  Gulfport  purchased  a  5%  ownership  interest  in  Tatex 
Thailand III, LLC, or Tatex III, at a cost of $850,000. In December 2009, Gulfport purchased 
an additional approximately 12.9% ownership interest at a cost of approximately $3.4 million 
bringing our total ownership interest to approximately 17.9%.  Tatex III owns a concession 
covering  approximately  one  million  acres.  Tatex  III  recently  completed  a  3-D  seismic 
survey on this concession.  The first well drilled on the concession in 2010 was temporarily 
abandoned pending further scientific evaluation. A second well was drilled to a depth of 
15,026 feet and logged approximately 5,000 feet of apparent possible gas saturated column. The well experienced gas 
shows and carried a flare measuring up to 25 feet throughout drilling below the intermediate casing point of 9,695 feet. 

NIOBRARA SHALE

Year End ’10 Proved Reserves:
0.36 MMBOE

Year End ’10 Leasehold Position:
19,445

The Niobrara Formation oil play in northwestern 
Colorado is located between the Piceance Basin 
to the south and the Sand Wash Basin to the north. 
Rocks mainly consist of interbedded organic-rich 
shales,  calcareous  shales  and  marlstones.  It  is 
the  fractured  marlstone  intervals  locally  known 
as the Buck Peak, Tow Creek and Wolf Mountain 
benches that account for the majority of the areas production. These fractured carbonate 
reservoirs  are  associated  with  anticlinal,  synclinal  and  monoclinal  folds,  and  fault  zones. 
This proven oil accumulation is considered to be continuous in nature and lightly explored. 
Source rocks are predominantly oil prone and thermally mature with respect oil generation. 
The producing intervals are geologically equivalent to the Niobrara reservoirs of the DJ and 
Powder River Basins which are currently emerging as a major crude resource play.   Gulfport 
recompleted one well at Niobrara during 2010.  Gulfport is in the process of permitting a 
60  square  mile  3-D  seismic  survey  over  its  Craig  Dome  prospect  and  expects  to  begin 
shooting in mid-2011.

GULFPORT ANNUAL REPORT 2010

S HA REHOLDER LETTER

Dear Fellow Shareholders,

2010  was  a  year  of  significant  growth  and 
accomplishments  for  Gulfport’s  employees  and 
shareholders.    With  record  activity,  our  team 
generated  production  growth  of  18%  while 
maintaining discipline in economic efficiency and 
delivering  top-tier  profit  margins,  with  EBITDA 
at 70% of oil and gas revenues. Key financial and 
operational highlights for the year included: 

•  Total net production increased 18% to 1.98 

million barrels of oil equivalent;

•  Oil and gas revenues increased 49% to 

$127.6 million;

•  EBITDA increased 61% to $89.7 million;

•  Cash flow from operating activities increased 

62% to $87.8 million; and 

•  Earnings per fully diluted share increased

95% to $1.07.

Underlying these solid performance metrics is a 
focused strategy and a tremendous set of assets.  
Today,  Gulfport’s  oil  dominant  asset  portfolio 
places  us  in  the  unique  and  advantageous 
position of being able to invest capital and grow 
production at very attractive returns.  Thanks to 
our  long-term  bias  towards  crude  oil,  we  have 
captured an irreplaceable resource base of high-
return,  oil-focused  opportunities  capable  of 
generating significant organic growth for at least 
the next decade. 

Recent  advances  in  drilling  and  completion 
technology  have  caused  the  Wolfberry  play 
in  the  Permian  Basin  to  emerge  as  one  of  the 
hottest oil plays in North America, and Gulfport 
has  captured  a  significant  presence  in  the  play.  
With  over  14,700  net  acres  under  lease  in  the 
Wolfberry,  we  have  identified  over  500  gross 
drilling  locations  on  40-acre  spacing,  a  number 
which  could  potentially  double  with  further 
development  of  the  20-acre  spacing  concept.  
We  currently  anticipate  that  our  Wolfberry 
drilling  inventory  and  planned  capital  spending 

will  support  a  meaningful  increase  in  near-term 
production  and  look  for  the  Wolfberry  to  be  a 
major contributor to Gulfport’s future growth.    

Second only to Saudi Arabia in size, the Canadian 
oil  sands  is  expected  to  be  a  crucial  element  in 
supplying  the  world’s  future  energy  needs,  and 
Grizzly Oil Sands (“Grizzly”), a company in which 
Gulfport  owns  a  24.9999%  interest,  has  secured 
a meaningful percentage of the play.  2010 was a 
landmark year for Grizzly along the road toward 
commercial development.  In March 2010, Grizzly 
filed  an  application  for  the  development  of  an 
11,300  barrel  per  day  oil  sands  project  at  Algar 
Lake  which,  upon  completion,  is  expected  to 

operate at an average capacity of 10,000 barrels 
per day over a design life of 30 years.  Meanwhile, 
in  December  of  2010,  Grizzly  received  a  reserve 
and resource assessment report which estimated 
that  Grizzly  had  98  million  barrels  of  Proved 
+  Probable  (2P)  reserves  attributable  to  the 
Algar  Lake  Project,  1.850  billion  barrels  of  Best 
Estimate  (P50)  Contingent  Resource  and  202 
million barrels of Best Estimate (P50) Prospective 
Resource.    This  report  covered  approximately 
34% of Grizzly’s acreage and equated to over 500 
million  barrels  of  recoverable  oil  resource  net  to 
Gulfport’s  interest.    We  expect  the  Canadian  oil 
sands to be a source of potential resource growth 
for Gulfport in years to come as Grizzly executes 
exploratory  drilling  programs  to  delineate  the 
remaining 66% of its acreage.     

In  pursuit  of  world  class  reserves,  Gulfport 
owns  interests  in  equity  investments  providing 
exposure  to  four  onshore  concession  blocks  in 

northeastern Thailand.  After shooting the largest 
onshore  3-D  seismic  survey  in  Southeast  Asia 
during 2009, Tatex Thailand III LLC (“Tatex III”), a 
company in which Gulfport owns a 17.9% interest, 
spudded two exploratory wells during 2010.  The 
second exploratory well, TEW-E, was drilled to a 
total depth of 15,026 feet and logged over 5,000 
feet  of  apparent  possible  gas  saturated  column.  
TEW  experienced  gas  shows  and  carried  a  flare 
measuring up to 25 feet throughout drilling below 
the intermediate casing point of 9,695 feet.  Tatex 
III will to conduct a flow test of the TEW-E in an 
attempt to quantify the size of the discovery.   

2.4  million  barrels  of  oil  equivalent,  generating 
approximately 16% production growth while still 
continuing to invest in high impact projects such 
as  Grizzly.    In  addition,  2011  marks  Gulfport’s 
entry  into  the  Utica  Shale  of  Eastern  Ohio.   We 
believe the Utica Shale will have three windows 
of  maturity  (oil,  wet  gas  and  dry  gas),  similar 
to  the  Eagle  Ford  Shale  in  South  Texas.    We 
are targeting acreage within the mature oil and 
wet  gas  windows  of  the  play.    Our  initial  entry 
into  the  Utica  Shale  included  commitments  for 
approximately 13,750 net acres which we expect 
to be able to grow significantly over time.  

Gulfport’s  legacy  assets  in  Southern  Louisiana 
provide a strong base of free cash flow generation, 
fueling our efforts to capture resource and build 
upon our existing asset base.  West Cote Blanche 
Bay continues to deliver repeatable, high-return 
development  drilling  opportunities  while  recent 
exploratory  activities  at  Hackberry  have  shown 
a  considerable  amount  of  promise,  potentially 
pointing  to  another  source  of  considerable 
growth  for  Gulfport  going  forward.    Both  areas 
receive  the  benefit  of  high  quality  Louisiana 
Sweet  pricing,  which  adds  to  their  already 
compelling rates of return.  

Finally,  a  strategic  acquisition  in  the  Niobrara 
Shale of Western Colorado in May 2010 provided 
Gulfport an entry point and meaningful position 
in  another  promising  oil-levered  play.    We 
continue  to  acquire  attractive  acreage  in  the 
play and believe that its successful development 
could  provide  a  catalyst  for  further  crude  oil 
reserve and production growth.

LOOKING AHEAD: 

Gulfport  is  poised  to  have  a  record  year  in 
2011.    Our  current  capital  plan  targets  2011 
production  to  be  in  the  range  of  2.2  million  to 

With  a  2011  calendar  full  of  potential  value 
creating catalysts, the opportunities ahead of us 
today are some of the most exciting in Gulfport’s 
history.  Ultimately, Gulfport’s strong oil-levered, 
continued  focus  towards  capturing  valuable 
resource  and  proven  capacity  for  production 
and  cash  flow  growth  make  me  confident  that 
the outlook ahead is bright. 

We thank you for your continued support.

Respectfully, 

Mike Liddell  
Chairman of the Board      Chief Executive Officer

ITEM 1. DESCRIPTION OF BUSINESS

General

PART I

We are an independent oil and natural gas exploration and production company with our principal producing

properties located along the Louisiana Gulf Coast in the West Cote Blanche Bay, or WCBB, and Hackberry
fields, and in West Texas in the Permian Basin. In 2010, we acquired an acreage position in the Niobrara
Formation of Western Colorado. We also hold a significant acreage position in the Alberta oil sands in Canada
through our interest in Grizzly Oil Sands ULC, or Grizzly, and have interests in entities that operate in Southeast
Asia, including the Phu Horm gas field in Thailand. We seek to achieve reserve growth and increase our cash
flow through our annual drilling programs.

In 2010, at our WCBB field, we recompleted 72 wells and drilled 23 wells for a total cost of approximately
$40.9 million as of December 31, 2010. All 23 new wells drilled at WCBB in 2010 were completed as producing
wells. During 2011, we currently anticipate drilling 20 to 24 wells and recompleting 60 wells at our WCBB field
for an estimated aggregate cost of $36.0 to $38.0 million. In the fourth quarter of 2010, production at WCBB was
293,372 net barrels of oil equivalent, or BOE, or an average of 3,189 BOE per day, 97% of which was from oil
and 3% of which was from natural gas. From January 1, 2011 through February 28, 2011, our average net daily
production at WCBB was 2,721 BOE, 97% of which was from oil and 3% of which was from natural gas.

In 2010, at our East Hackberry field, we recompleted ten wells and drilled eight wells for a total cost of

approximately $20.0 million as of December 31, 2010. All wells drilled during 2010 were completed as
producing wells. During 2011, we currently anticipate drilling seven to ten wells and recompleting five wells for
an aggregate estimated cost of $24.0 to $26.0 million. In the fourth quarter of 2010, net production at East
Hackberry was 157,349 BOE, or an average of 1,710 BOE per day, 96% of which was from oil and 4% of which
was from natural gas. From January 1, 2011 through February 28, 2011, our average net daily production at East
Hackberry was 1,899 BOE, 93% of which was from oil and 7% of which was from natural gas.

In the fourth quarter of 2010, net production at West Hackberry was 3,121 BOE, or an average of 34 BOE
per day, 100% of which was from oil. From January 1, 2011 through February 28, 2011, our average net daily
production at West Hackberry was 35 BOE, 100% of which was from oil.

In 2007, we acquired approximately 4,100 net acres in West Texas in the Permian Basin with production at
the time of acquisition from 32 gross (16 net) wells, predominately from the Wolfcamp formation. Subsequently,
we acquired approximately 10,600 additional net acres, which brought our total net acreage position in the
Permian Basin to approximately 14,700 net acres. During the year ended December 31, 2010, 25 gross (11 net)
wells were drilled and four gross (two net) wells were recompleted on this acreage. As of March 1, 2011, 24 of
the 25 wells had been completed and one well was awaiting completion. We currently anticipate that 40 to 42
gross (19 to 20 net) wells will be drilled and ten gross (five net) wells will be recompleted on this acreage in
2011 for an estimated aggregate net cost of $37.0 to $39.0 million. In the fourth quarter of 2010, net production
from our Permian acreage was 72,791 BOE, or an average of 791 BOE per day, 84% of which was from oil and
natural gas liquids and 16% of which was from natural gas. From January 1, 2011 through February 28, 2011,
our average daily net production from our Permian acreage was 787 BOE, 87% of which was from oil and
natural gas liquids and 13% of which was from natural gas.

Effective as of April 1, 2010, we acquired leasehold interests in the Niobrara Formation in Colorado and
held leases for 19,172 net acres as of March 1, 2011. During the year ended December 31, 2010, we recompleted
one gross (0.4 net) well on this acreage. In the fourth quarter of 2010, net production at Niobrara was 3,380 BOE,
or an average of 37 BOE per day, 100% of which was from oil. From January 1, 2011 through February 28,
2011, our average net daily production at Niobrara was 36 BOE, 100% of which was from oil. We are in the
process of permitting a 60 square mile 3-D seismic survey and expect to begin shooting in mid-2011.

2

As of December 31, 2010, we held approximately 900 net acres in the Williston Basin of western North
Dakota and eastern Montana with interests in five wells and an overriding royalty interest in wells drilled prior to
our sale, wells drilled subsequent to our sale and wells that might be drilled in the future. In the fourth quarter of
2010, our net production from this acreage was 6,522 BOE, or an average of 71 BOE per day, 95% of which was
from oil and natural gas liquids and 5% of which was from natural gas. From January 1, 2011 through
February 28, 2011, our average daily net production from our Bakken acreage was 64 BOE, 93% of which was
from oil and 7% of which was from natural gas.

During the third quarter of 2006, we, through our wholly-owned subsidiary Grizzly Holdings Inc.,
purchased a 24.9% interest in Grizzly. The remaining interests in Grizzly are owned by entities controlled by
Wexford Capital LP, or Wexford. During 2006 and 2007, Grizzly acquired leases in the Athabasca region located
in the Alberta Province near Fort McMurray within a few miles of other existing oil sands projects. Grizzly has
approximately 534,000 acres under lease and our total net investment in Grizzly was approximately $46.5
million, including a note receivable of $20.0 million, at December 31, 2010. To date, Grizzly has drilled an
aggregate of 199 core holes and three water supply test wells, tested nine separate lease blocks and conducted a
seismic program. In March 2010, Grizzly filed an application in Alberta, Canada for the development of an
11,300 barrel per day oil sand SAGD facility at Algar Lake. Grizzly expects regulatory approval by mid-2011,
followed by an anticipated construction period of 18 months leading to first production. Grizzly recently received
the supplemental information request, or SIR, pertaining to its Algar Lake project application from the Alberta
regulatory agencies. This is the standard process by which the Alberta regulatory agencies request additional
information on all oil sands project applications. The SIR was received in a timeframe consistent with anticipated
timeline for project approval. The engineering and procurement contract for Grizzly’s proposed steam assisted
gravity drainage, or SAGD, facility at Algar Lake has been awarded to SNC-Lavin. Work on the detailed
engineering design is underway out of Grizzly’s Calgary office and the detailed design of the project is expected
to be complete by April 2011. Grizzly’s currently contemplated 2011 activities include the completion of the
2010/2011 core hole drilling activity, seismic program and the initial preparations for the Algar Lake SAGD
facility.

We own a 23.5% ownership interest in Tatex Thailand II, LLC, or Tatex. The remaining interests in Tatex

are owned by entities controlled by Wexford. Tatex, a privately held entity, holds 85,122 of the 1,000,000
outstanding shares of APICO, LLC, or APICO, an international oil and gas exploration company. APICO has a
reserve base located in Southeast Asia through its ownership of concessions covering approximately two million
acres which includes the Phu Horm Field.

We also own a 17.9% ownership interest in Tatex Thailand III, LLC, or Tatex III. Approximately 68.7% of

the remaining interests in Tatex III are owned by entities controlled by Wexford. Tatex III owns a concession
covering approximately one million acres. During 2010, Tatex completed a 3-D seismic survey on this
concession. The first well drilled on our concession in 2010 was temporarily abandoned pending further
scientific evaluation. A second well was drilled to a depth of 15,026 feet and logged approximately 5,000 feet of
apparent possible gas saturated column. The well experienced gas shows and carried a flare measuring up to
25 feet throughout drilling below the intermediate casing point of 9,695 feet. Tatex III is currently in the process
of completing the well.

As of December 31, 2010, we had 22.4 million barrels of oil equivalent, or MMBOE, of proved reserves
with a present value of estimated future net revenues, discounted at 10%, or PV-10, of approximately $392.6
million and associated standardized measure of discounted future net cash flows of approximately $315.5
million. See Item 2. “Properties—Proved Oil and Natural Gas Reserves” for our definition of PV-10, a
non-GAAP financial measure, and a reconciliation of our standardized measure of discounted future net cash
flows to PV-10.

West Cote Blanche Bay Field

Location and Land

The WCBB field is located approximately five miles off the coast of Louisiana in a shallow bay with water
depths averaging eight to ten feet. We own a 100% working interest (80.108% net revenue interest, or NRI), and
are the operator, in depths above the base of the 13900 Sand which is located at 11,320 feet. In addition, we own
a 40.40% non-operated working interest (29.95% NRI) in depths below the base of the 13900 Sand, which is
operated by Chevron Corporation. Our leasehold interests at WCBB contain 5,668 gross acres.

Area History and Production

Texaco, now Chevron Corporation, drilled the discovery well in this field in 1940 based on a seismic and

gravitational anomaly. WCBB was subsequently developed on an even 160-acre pattern for much of the
remainder of the decade. Developmental drilling continued and reached its peak in the 1970s when over 300
wells were drilled in the field. Of the 973 wells drilled as of December 31, 2010, 880 were completed as
producing wells. As a result, the field has a historic success rate of 90% for all wells drilled. From the date of our
acquisition of WCBB in 1997 through December 31, 2010, we drilled 162 new wells, 146 of which were
productive, for a 90% success rate. As of December 31, 2010, estimated field cumulative gross production was
191.3 MMBOE and 236.4 billion cubic feet, or Bcf, of gas. Of the 973 wells drilled in WCBB as of
December 31, 2010, 84 were producing, 179 were shut-in, nine were producing intermittently and five were
being used as salt water disposal wells. The other 696 wells have been plugged and abandoned.

In 1991, Texaco conducted a 70 square mile 3-D seismic survey with 1,100 shot points per mile that
processed out 100 fold. In 1993, an undershoot survey around the crest and production facilities was completed.
We own the rights to the seismic data. In December 1999, we completed the reprocessing of the seismic data and
our technical staff developed prospects from the data. The reprocessed data has enabled us to identify prospects
in areas of the field that would have otherwise remained obscure. During the first half of 2005, we again
reprocessed the seismic data using advanced seismic data processing.

Geology

WCBB overlies one of the largest salt dome structures on the Gulf Coast. The field is characterized by a
piercement salt dome, which created traps from the Pleistocene through the Miocene formations. The relative
movements affected deposition and created a complex system of fault traps. The compensating fault sets
generally trend northwest to southeast and are intersected by sets having a major radial component. Later-stage
movement caused extension over the dome and a large graben system (a downthrown area bounded by normal
faults) was formed.

There are over 100 distinct sandstone reservoirs recognized throughout most of the field, and nearly 200

major and minor discrete intervals have been tested. Within the 973 wells that had been drilled in the field as of
December 31, 2010, over 4,000 potential zones have been penetrated. These sands are highly porous and
permeable reservoirs primarily with a strong water drive.

WCBB is a structurally and stratigraphically complex field. All of the proved undeveloped, or PUD,
locations at WCBB are adjacent to faults and abut at least one fault. Our drilling programs are designed to
penetrate each PUD trap with a new wellbore in a structurally optimum position, usually very close to the fault
seal. The majority of these wells have been, and new wells drilled in connection with our drilling programs will
be, directionally drilled using steering tools and downhole motors. The tolerance for error in getting near the fault
is low, so the complex faulting does introduce the risk of crossing the fault before encountering the zone of
interest, which could result in part or all of the zone being absent in the borehole. This, in turn, can result in
lower than expected or no reserves for that zone. The new wellbores eliminate the mechanical risk associated
with trying to produce the zone from an old existing wellbore, while the wellbore locations are selected in an
effort to more efficiently drain each reservoir. The vast majority of the PUD targets are up-dip offsets to wells
that produced from a sub-optimal position within a particular zone. Our inventory of prospects at WCBB as of
December 31, 2010 included 29 PUD wells. The drilling schedule used in the reserve report anticipates that all of
those wells will be drilled by 2013.

Facilities

We own and operate a production facility at WCBB that includes four production tank batteries, eight

natural gas compressors, a storage barge facility, a dock, a dehydration unit and a salt water disposal system.

Recent and Future Activity

In 2010, we recompleted 72 gross and net wells and drilled 23 gross and net wells at WCBB. All 23 new
wells were completed as producers. As of March 11, 2011, we had drilled two wells and recompleted twelve
wells during 2011. Of the 23 wells drilled in 2010, 17 were considered deep wells. The 23 productive wells, with
total depths ranging from 1,800 to 9,560 feet, have approximately 2,063 feet of aggregate apparent net pay. We
currently anticipate drilling 20 to 24 gross and net wells and recompleting 60 gross and net wells at WCBB
during 2011.

Production Status

In the fourth quarter of 2010, production at WCBB was 293,372 net BOE, or an average of 3,189 BOE per

day, 97% of which was from oil and 3% of which was from natural gas. From January 1, 2011 through
February 28, 2011, our average net daily production at WCBB was 2,721 BOE, 97% of which was from oil and

5

3% of which was from natural gas. The decrease in production was due to operating inefficiencies with wells,
machinery and equipment resulting from the sub-freezing weather conditions during January and February 2011
in Southern Louisiana.

East Hackberry Field

Location and Land

The East Hackberry field in Louisiana is located along the western shore and the land surrounding Lake
Calcasieu, 15 miles inland from the Gulf of Mexico. We own a 100% working interest (approximately 79.424%
average NRI) in certain producing oil and natural gas properties situated in the East Hackberry field. We hold
beneficial interests in approximately 4,870 acres, including the Erwin Heirs Block, which is located on land, and
the adjacent State Lease 50 Block, which is located primarily in the shallow waters of Lake Calcasieu. We also
hold 2,868 net acres subject to a two-year exploration agreement we entered into with an active gulf coast
operator. We are the designated operator under the agreement and will participate in proposed wells with at least
a 70% working interest. We have licensed approximately 54 square miles of 3-D seismic data covering a portion
of the area and are reprocessing the data.

Area History and Production

The East Hackberry field was discovered in 1926 by Gulf Oil Company, now Chevron Corporation, by a

gravitational anomaly survey. The massive shallow salt stock presented an easily recognizable gravity anomaly
indicating a productive field. Initial production began in 1927 and has continued to the present. The estimated
cumulative oil and condensate production through 2010 was over 1,015 MBOE and 330 Bcf of casinghead gas
production. A total of 201 wells have been drilled on our portion of the field. As of December 31, 2010, 27 wells
had daily production, 74 were shut-in and two had been converted to salt water disposal wells. The remaining 98
wells had been plugged and abandoned.

Geology

The Hackberry field is a major salt intrusive feature, elliptical in shape as opposed to a classic “dome,”

divided into east and west field entities by a saddle. Structurally, our East Hackberry acreage is located on the
eastern end of the Hackberry salt ridge. There are over 30 pay zones at this field. The salt intrusion formed a
series of structurally complex and steeply dipping fault blocks in the Lower Miocene and Oligocene age rocks.
These fault blocks serve as traps for hydrocarbon accumulation. Our wells currently produce from perforations
found between 5,100 and 12,200 feet.

Facilities

We have a field office that serves both the East and West Hackberry fields. In addition, we completed

installation of a new production barge at the East Hackberry field in the second quarter of 2007. The barge is
designed to have the ability to process on a per day basis approximately 5,000 barrels of liquid, 30 Mmcf of high
pressure natural gas, 6.5 Mmcf of low pressure natural gas and 10,000 barrels of salt water.

Recent and Future Activity

During 2005, we completed a proprietary 42 square mile 3-D seismic survey at East Hackberry, the first
modern seismic program undertaken at this field. We believe that this 3-D seismic data enhances our probability
of drilling success, and we continue to evaluate the 3-D seismic data to identify additional drilling locations.
During 2010 at East Hackberry, we recompleted ten gross and net wells and drilled six gross and net land wells
and two gross and net wells on water. All of the eight wells drilled during 2010 were completed as producing
wells. As of March 11, 2011, we had recompleted three wells during 2011, drilled one well and were in the
process of drilling two additional wells. We currently intend to drill seven to ten gross and net wells and
recomplete five gross and net wells at East Hackberry during 2011.

Production Status

In the fourth quarter of 2010, net production at East Hackberry was 157,349 BOE, or an average of 1,710

BOE per day, 96% of which was from oil and 4% of which was from natural gas. From January 1, 2011 through
February 28, 2011, our average net daily production at East Hackberry was 1,899 BOE, 93% of which was from
oil and 7% of which was from natural gas. The increase in production in 2011 is a result of our 2011 drilling
activities.

West Hackberry Field

Location and Land

The West Hackberry field is located on land and is five miles west of Lake Calcasieu in Cameron Parish,
Louisiana, approximately 85 miles west of Lafayette and 15 miles inland from the Gulf of Mexico. We own a
100% working interest (approximately 87.5% NRI) in 592 acres within the West Hackberry field. Our leases at
West Hackberry are located within two miles of one of the United States Department of Energy’s Strategic
Petroleum Reserves.

Area History

The first discovery well at West Hackberry was drilled in 1938 and the field was developed by Superior Oil
Company, now ExxonMobil Corporation, between 1938 and 1988. The estimated cumulative oil and condensate
production through 2010 was 274 MBOE and 140 Bcf of natural gas. There have been 36 wells drilled to date on
our portion of West Hackberry. Currently, three are producing, 22 are shut-in and one has been converted to a
saltwater disposal well. The remaining ten wells have been plugged and abandoned.

Structurally, our West Hackberry acreage is located on the western end of the Hackberry salt ridge. There

are over 30 pay zones at this field. West Hackberry consists of a series of fault-bounded traps in the
Oligocene-age Vincent and Keough sands associated with the Hackberry Salt Ridge. Recoveries from these
thick, porous, water-drive reservoirs have resulted in per well cumulative production of almost 700 MBOE.

Production Status

In the fourth quarter of 2010, net production at West Hackberry was 3,121 BOE, or an average of 34 BOE
per day. From January 1, 2011 through February 28, 2011, our average net daily production at West Hackberry
was 35 BOE and was 100% oil.

Facilities

We have land-based production and processing facilities located at the West Hackberry field and maintain a

field office that serves both the East and West Hackberry fields.

Permian Basin (West Texas)

Location and Land

We acquired approximately 4,100 net acres and 32 gross (16 net) producing wells in West Texas (near

Midland) in the Permian Basin effective November 1, 2007. Subsequently, we acquired 10,600 additional net
acres, which brought our total net acreage position in the Permian Basin to approximately 14,700 net acres as of
December 31, 2010. The Permian Basin area covers a significant portion of western Texas and eastern New
Mexico and is considered one of the major producing basins in the United States. The terrain in the Permian
Basin is semi-arid mesquite-mixed grassland steppe. Windsor Energy LLC, an entity controlled by Wexford, is
the operator of this field.

Area History

The Permian Basin formed as an area of rapid Mississippian-Pennsylvanian subsidence in the foreland of

the Ouachita Foldbelt. The Wolfcamp play was a long-established reservoir in West Texas, first found in the
1950s as wells aiming for deeper targets occasionally intersected slump blocks or reef facies with reservoir
properties. Exploration with 2-D seismic located additional fields, but it was not until the use of 3-D seismic in
the 1990s that the greater extent of the Wolfcamp prospects was revealed. During the late 1990s, Arco began a
drilling program targeting the Spraberry formation at 10,000 feet and then drilled another 200 to 300 feet to pick
up the upper part of the Wolfcamp formation. Henry Petroleum, a private firm, owned interest in the Pegusas
field in Midland and Upton counties. While drilling in the same area as the Arco project, Henry Petroleum
decided to drill completely through the Wolfcamp section as Devonian wells. Henry Petroleum mapped the trend
and began acquiring acreage and drilling wells using multiple slick-water fracs across the entire Wolfcamp
interval. In 2005, former members of Henry Petroleum’s Wolfcamp team formed their own private company,
ExL Petroleum, and began replicating Henry Petroleum’s program. After ExL had drilled 32 productive
Wolfcamp/Spraberry wells through late 2007, they decided to monetize approximately 15% of their acreage
position which enabled us to participate in this play. Recent advancements in enhanced recovery techniques
continue to make the basin an active play for exploration and production companies. As of December 31, 2010,
we held interests in 82 gross (40 net) producing wells.

Geology

The Wolfcamp/Spraberry play, which we refer to as Wolfberry, of the Midland Basin lies in the area where

the historically productive Spraberry trend geographically overlaps the productive area of the emerging
Wolfcamp carbonate play. The Wolfcamp is characterized by an approximately 2,000 feet section of organic rich
basin floor debris flows shed from the Central Basin Platform. The best reservoir rock within the section is
generally found in close proximity to the Central Basin Platform.

Wolfberry well reserves are typically approximately 80% from the Wolfcamp section and 20% from the
Spraberry section. Pinnacle Energy Services, LLC, an independent petroleum engineering firm, has estimated
that at December 31, 2010, proved reserves net to our interest in these assets were approximately 14.5 million
BOE, of which 16% were classified as proved developed producing, or PDP. Proved undeveloped, or PUD,
reserves included in this estimate were from 226 gross well locations on 40-acre units. The proved reserves are
located in the Wolfcamp and Spraberry formations, which are generally characterized as long-lived, with
predictable production profiles.

Production Status

In the fourth quarter of 2010, net production from the Permian field was 72,791 BOE, or an average of 791
BOE per day, 84% of which was from oil and natural gas liquids, and 16% of which was from natural gas. From
January 1, 2011 through February 28, 2011, our average daily net production from our Permian acreage was 787
BOE, 87% of which was from oil and natural gas liquids and 13% of which was from natural gas. The slight
production decrease was the result of the unusual sub-freezing weather conditions during January and February
2011.

Facilities

There are typical land oil and gas processing facilities in the Permian Basin. Our facilities located at well

locations include storage tank batteries, oil/gas/water separation equipment and pumping units.

Recent and Future Activity

In 2010, 25 gross (11 net) wells were drilled in our Permian acreage. As of March 11, 2011, four gross (two

net) wells had been recompleted and five gross (2.5 net wells) have been drilled on this acreage, three of which
were waiting on completion and two were currently drilling. We have identified 226 gross future development
drilling locations. We currently expect an estimated 40 to 42 gross (19 to 20 net) wells to be drilled on our
acreage in 2011. The wells are expected to be drilled to approximately 10,200 feet.

Niobrara Formation (Western Colorado)

Location and Land

Effective as of April 1, 2010, we acquired leasehold interests in the Niobrara Formation in western

Colorado, and held leases for 19,172 acres as of March 1, 2011. We are the operator on the acreage.

Area History

The Niobrara Formation is a shale oil rock formation located in Colorado, Northwest Kansas, Southwest

Nebraska, and Southeast Wyoming. Oil and natural gas can be found at depths of 3,000 – 14,000 feet and is
drilled both vertically and horizontally. The Upper Cretaceous Niobrara formation has emerged as another
potential crude oil resource play in various basins throughout the northern Rocky Mountain region. As with most
resource plays, the Niobrara has a history of producing through conventional technology with some of the earliest
production dating back to the early 1900s. Natural fracturing has played a key role in producing the Niobrara
historically due to the low porosity and low permeability of the formation. Because of this, conventional
production has been very localized and limited in area extent. We believe the Niobrara can be produced on a
more widespread basis using today’s horizontal multi-stage fracture stimulation technology where the Niobrara is
thermally mature.

Geology

The Niobrara Formation oil play in northwestern Colorado is located between the Piceance Basin to the
south and the Sand Wash Basin to the north. Rocks mainly consist of interbedded organic-rich shales, calcareous
shales and marlstones. It is the fractured marlstone intervals locally known as the Buck Peak, Tow Creek and
Wolf Mountain benches that account for the majority of the areas production. These fractured carbonate
reservoirs are associated with anticlinal, synclinal and monoclinal folds, and fault zones. This proven oil
accumulation is considered to be continuous in nature and lightly explored. Source rocks are predominantly oil
prone and thermally mature with respect oil generation. The producing intervals are geologically equivalent to
the Niobrara reservoirs of the DJ and Powder River Basins which are currently emerging as a major crude
resource play.

Production Status

In the fourth quarter of 2010, net production from our Niobrara acreage was 3,380 BOE, or an average of 37

BOE per day, 100% of which was from oil. From January 1, 2011 through February 28, 2011, our average daily
net production from our Niobrara acreage was 36 BOE, 100% of which was from oil.

Facilities

There are typical land oil and gas processing facilities in the Niobrara Formation. Our facilities located at

well locations include storage tank batteries, oil/gas/water separation equipment and pumping units.

Recent and Future Activity

We recompleted one well at Niobrara during 2010. We are in the process of permitting a 60 square mile 3-D

seismic survey over our Craig Dome prospect and expect to begin shooting in mid-2011. We currently intend to
drill four to five gross wells at Niobrara during 2011.

Bakken

Location and Land

The Bakken Shale is located in the Williston Basin areas of western North Dakota and eastern Montana.

During 2005, we purchased a 20% ownership interest in Windsor Bakken, LLC, or Bakken. The remaining
interests in Bakken were owned by entities controlled by Wexford. Beginning in 2005, Bakken acquired leases
on undeveloped acreage in the Williston Basin. As of December 31, 2007, Bakken had commenced participating
in the drilling of some of its undeveloped acreage. Effective January 1, 2008, we acquired a direct, undivided
20% interest in Bakken’s assets in redemption of our 20% interest in Bakken. During May 2009, we sold
approximately 12,270 net acres and approximately 190 net BOEPD of production for approximately $13.0
million, with an effective date of April 1, 2009. During September 2009, we sold approximately 5,721 net acres
for approximately $5.8 million with an effective date of July 1, 2009. As of December 31, 2010, we held
approximately 900 net acres, interests in five wells and an overriding royalty interest in wells drilled prior to our
sale, wells drilled subsequent to our sale and wells that might be drilled in the future.

Production Status

In the fourth quarter of 2010, net production from our Bakken acreage was 6,522 BOE, or an average of 71

BOE per day, 95% of which was from oil and natural gas liquids and 5% of which was from natural gas. From
January 1, 2011 through February 28, 2011, our average net daily production from this acreage was 64 BOE, of
which 93% was from oil and 7% was from natural gas.

Facilities

There are typical land oil and gas processing facilities in the Williston Basin. The facilities located at well

locations include storage tank batteries, oil/gas/water separation equipment and pumping units.

Recent and future activities

One gross well was drilled on our acreage in 2010. We have no activities currently scheduled for 2011 in the

Williston Basin.

Additional Properties

Louisiana. In addition to our interests in the WCBB, East Hackberry and West Hackberry fields, we also
own working interests and overriding royalty interest in various fields in Louisiana as described in the following

Thailand. During 2005, we purchased a 23.5% ownership interest in Tatex Thailand II, LLC, or Tatex, at a

cost of $2.4 million. The remaining interests in Tatex are owned by entities controlled by Wexford. Tatex, a
privately held entity, holds 85,122 of the 1,000,000 outstanding shares of APICO, LLC, or APICO, an
international oil and gas exploration company. APICO has a reserve base located in Southeast Asia through its
ownership of concessions covering approximately two million acres which includes the Phu Horm Field. During

10

the year ended December 31, 2010, we received $565,000 in distributions, reducing our total investment in Tatex
to $1.9 million. Our investment is accounted for on the equity method. Tatex accounts for its investment in
APICO using the cost method. In December 2006, first gas sales were achieved at the Phu Horm field located in
northeast Thailand. Phu Horm’s initial gross production was approximately 60 million cubic feet per day. For
December 2010, net gas production was approximately 98 MMcf per day and condensate production was 477
barrels per day. Hess Corporation operates the field with a 35% interest. Other interest owners include APICO
(35% interest), PTTEP (20% interest) and ExxonMobil (10% interest). Our gross working interest (through Tatex
as a member of APICO) in the Phu Horm field is 0.7%. Due to the fact that our ownership in the Phu Horm field
is indirect and Tatex’s investment in APICO is accounted for by the cost method, these reserves are not included
in our year-end reserve information.

During the first quarter of 2008, we purchased a 5% ownership interest in Tatex Thailand III, LLC, or Tatex

III, at a cost of $850,000. In December 2009, we purchased an additional approximately 12.9% ownership
interest at a cost of approximately $3.4 million bringing our total ownership interest to approximately 17.9%.
Approximately 68.7% of the remaining interests in Tatex III are owned by entities controlled by Wexford. Tatex
III owns a concession covering approximately one million acres. Tatex III recently completed a 3-D seismic
survey on this concession. During the year ended December 31, 2010, we paid $402,000 in cash calls, bringing
our total investment in Tatex III to $4.7 million. The first well drilled on our concession in 2010 was temporarily
abandoned pending further scientific evaluation. A second well was drilled to a depth of 15,026 feet and logged
approximately 5,000 feet of apparent possible gas saturated column. The well experienced gas shows and carried
a flare measuring up to 25 feet throughout drilling below the intermediate casing point of 9,695 feet. Tatex III is
currently in the process of completing the well.

Grizzly Oil Sands. During the third quarter of 2006, we, through our wholly-owned subsidiary Grizzly
Holdings Inc., purchased a 24.9% interest in Grizzly. The remaining interests in Grizzly are owned by entities
controlled by Wexford. During 2006 and 2007, Grizzly acquired leases in the Athabasca region located in the
Alberta Province near Fort McMurray within a few miles from other existing oil sands projects. Grizzly has
approximately 534,000 acres under lease and our total net investment in Grizzly was approximately $46.5
million, including a note receivable of $20.0 million, at December 31, 2010. To date, Grizzly has drilled an
aggregate of 199 core holes and three water supply test wells, tested nine separate lease blocks and conducted a
seismic program. In connection with its 2010/2011 winter drilling program, Grizzly plans to drill a total of 71
core hole locations, 68 of which have been drilled to date. Upon the completion of the 2010/2011 drilling season,
Grizzly will have drilled 32 locations at Thickwood Hills, 14 locations at Firebag River, 17 locations at Algar
Lake, and eight total locations at Athabasca Rapids and Horse River. In March 2010, Grizzly filed an application
in Alberta, Canada for the development of an 11,300 barrel per day SAGD facility at Algar Lake. Grizzly expects
regulatory approval by mid-2011, followed by an anticipated construction period of 18 months leading to first
production. Grizzly recently received the supplemental information request, or SIR, pertaining to its Algar Lake
project application from the Alberta regulatory agencies. This is the standard process by which the Alberta
regulatory agencies request additional information on all oil sands project applications. The SIR was received in
a timeframe consistent with anticipated timeline for project approval. The engineering and procurement contract
for Grizzly’s proposed steam assisted gravity drainage facility at Algar Lake has been awarded to SNC-Lavin.
Work on the detailed engineering design is underway out of Grizzly’s Calgary office and the detailed design of
the project is expected to be complete by April 2011. Grizzly’s currently contemplated 2011 activities include the
completion of the 2010/2011 core hole drilling activity and the initial preparations for the Algar Lake SAGD
facility.

Competition and Markets

The oil and natural gas industry is intensely competitive, and we compete with other companies that have
greater resources. Many of these companies not only explore for and produce oil and natural gas, but also carry
on midstream and refining operations and market petroleum and other products on a regional, national or
worldwide basis. These competitors may be better positioned to take advantage of industry opportunities and to

11

withstand changes affecting the industry, such as fluctuations in oil and natural gas prices and production, the
availability of alternative energy sources and the application of government regulation.

The availability of a ready market for any oil and/or natural gas we produce depends on numerous factors
beyond the control of our management, including but not limited to the demand for oil and natural gas and the
level of domestic production and imports of oil, the proximity and capacity of gas pipelines, the availability of
skilled labor, materials and equipment, the effect of state and federal regulation of oil and natural gas production
and federal regulation of gas sold in interstate commerce. The oil and natural gas we produce in Louisiana is sold
to purchasers who service the areas where our wells are located. We sell the majority of our oil to Shell Trading
Company, or Shell. Shell takes custody of the oil at the outlet from our oil storage barge. Our production from
WCBB, other than the production sold under forward sales contracts, is being sold in accordance with the Shell
posted price for West Texas/New Mexico Intermediate crude plus or minus Platt’s trade month average P+ value,
plus or minus the Platt’s HLS/WTI trade month average differential less $2.70 per barrel for transportation.
During 2010, we sold 75% and 19% of our oil production to Shell and Windsor Energy Group, the operator of
our Permian wells, respectively, and 50%, 32%, and 10% of our natural gas production to Windsor Energy
Group, Chevron and Hilcorp Energy Company, respectively. During 2009, we sold 92% and 7% of our oil
production to Shell and Windsor Energy Group, the operator of our Permian wells, respectively, and 45%, 38%,
and 16% of our natural gas production to Windsor Energy Group, Chevron and Hilcorp Energy Company,
respectively. During 2008, we sold 87% of our oil production to Shell and 11% to Windsor Energy Group, 100%
of our natural gas liquids production to Windsor Energy Group, and 60%, 22%, and 16% of our natural gas
production to Chevron, Windsor Energy Group, and Hilcorp Energy Company, respectively. We may not
continue to have ready access to suitable markets for our future oil and natural gas production.

Oil and natural gas prices can be extremely volatile and are subject to substantial seasonal, political and

other fluctuations. The price at which the oil and natural gas we produce may be sold is uncertain and it is
possible that under some market conditions the production and sale of oil and natural gas from some or all of our
properties may not be economical. Because of all of the factors influencing the price of oil and natural gas, it is
impossible to accurately predict future prices.

To mitigate the effects of commodity price fluctuations, we were party to forward sales contracts for the sale

of 3,000 barrels of WCBB production per day at a weighted average daily price of $54.81 per barrel, before
transportation costs and differentials, for the period January 2010 through February 2010. For the period March
2010 through December 2010, we were party to forward sales contracts for the sale of 2,300 barrels of WCBB
production per day at a weighted average daily price of $58.24 per barrel before transportation costs and
differentials. We delivered approximately 45% of our 2010 production under these agreements.

In November 2010, we entered into fixed price swaps for 2,000 barrels of oil per day at a weighted average

price of $86.96 per barrel, before transportation costs and differentials, for the period January 2011 through
December 2011. Under the 2011 contracts, we have committed to deliver approximately 30% to 33% of our
estimated 2011 production. Such arrangements may expose us to risk of financial loss in certain circumstances,
including instances where production is less than expected or oil prices increase. These forward sales contacts
and fixed price swaps are accounted for as cash flow hedges and recorded at fair value pursuant to FASB
ASC 815, “Derivatives and Hedging,” and related pronouncements.

Regulation

Regulation of Gas and Oil Production

Oil and natural gas operations such as ours are subject to various types of legislation, regulation and other

legal requirements enacted by governmental authorities. This legislation and regulation affecting the oil and
natural gas industry is under constant review for amendment or expansion. Some of these requirements carry
substantial penalties for failure to comply. The regulatory burden on the oil and natural gas industry increases our
cost of doing business and, consequently, affects our profitability.

12

We own interests in a number of producing oil and natural gas properties located along the Louisiana Gulf

Coast, West Texas and the Niobrara Formation. The states in which our fields are located in regulate the
production and sale of oil and natural gas, including requirements for obtaining drilling permits, the method of
developing new fields and the spacing and operation of wells. In addition, regulations governing conservation
matters aimed at preventing the waste of oil and natural gas resources could affect the rate of production and may
include maximum daily production allowables for wells on a market demand or conservation basis.

Environmental Regulation

Our oil and natural gas exploration, development and production operations are subject to stringent laws and

regulations governing the discharge of materials into the environment or otherwise relating to environmental
protection. Numerous governmental agencies, such as the U.S. Environmental Protection Agency, or EPA, issue
regulations which often require difficult and costly compliance measures that carry substantial administrative,
civil and criminal penalties and may result in injunctive obligations for failure to comply. These laws and
regulations may require the acquisition of a permit before drilling commences, restrict the types, quantities and
concentrations of various substances that can be released into the environment in connection with drilling and
production activities, limit or prohibit construction or drilling activities on certain lands lying within wilderness,
wetlands, ecologically sensitive and other protected areas, require action to prevent or remediate pollution from
current or former operations, such as plugging abandoned wells or closing pits, result in the suspension or
revocation of necessary permits, licenses and authorizations, require that additional pollution controls be installed
and impose substantial liabilities for pollution resulting from our operations or relate to our owned or operated
facilities. The strict and joint and several liability nature of such laws and regulations could impose liability upon
us regardless of fault. Changes in environmental laws and regulations occur frequently, and any changes that
result in more stringent and costly pollution control or waste handling, storage, transport, disposal or cleanup
requirements could materially adversely affect our operations and financial position, as well as the oil and natural
gas industry in general. Our management believes that we are in substantial compliance with applicable
environmental laws and regulations and we have not experienced any material adverse effect from compliance
with these environmental requirements. This trend, however, may not continue in the future.

Waste Handling. The Resource Conservation and Recovery Act, as amended, or RCRA, and comparable
state statutes and regulations promulgated thereunder, affect oil and natural gas exploration, development and
production activities by imposing requirements regarding the generation, transportation, treatment, storage,
disposal and cleanup of hazardous and non-hazardous wastes. With federal approval, the individual states
administer some or all of the provisions of RCRA, sometimes in conjunction with their own, more stringent
requirements. Although most wastes associated with the exploration, development and production of crude oil
and natural gas are exempt from regulation as hazardous wastes under RCRA, such wastes may constitute “solid
wastes” that are subject to the less stringent requirements of non-hazardous waste provisions. However, there can
be no assurance that the EPA or the state or local governments will not adopt more stringent requirements for the
handling of non-hazardous wastes or categorize some non-hazardous wastes as hazardous for future regulation.
Indeed, legislation has been proposed from time to time in Congress to re-categorize certain oil and natural gas
exploration, development and production wastes as “hazardous wastes.” Any such changes in the laws and
regulations could have a material adverse effect on our capital expenditures and operating expenses.

Administrative, civil and criminal penalties can be imposed for failure to comply with waste handling
requirements. We believe that we are in substantial compliance with applicable requirements related to waste
handling, and that we hold all necessary and up-to-date permits, registrations and other authorizations to the
extent that our operations require them under such laws and regulations. Although we do not believe that the
current costs of managing our wastes as they are presently classified to be significant, any legislative or
regulatory reclassification of oil and natural gas exploration and production wastes could increase our costs to
manage and dispose of such wastes.

Remediation of Hazardous Substances. The Comprehensive Environmental Response, Compensation and

Liability Act, as amended, also known as CERCLA or the “Superfund” law, and analogous state laws, generally

13

imposes strict and joint and several liability, without regard to fault or legality of the original conduct, on classes
of persons who are considered to be responsible for the release of a “hazardous substance” into the environment.
These persons include the current owner or operator of a contaminated facility, a former owner or operator of the
facility at the time of contamination, and those persons that disposed or arranged for the disposal of the
hazardous substance at the facility. Under CERCLA and comparable state statutes, persons deemed “responsible
parties” may be subject to strict and joint and several liability for the costs of removing or remediating previously
disposed wastes (including wastes disposed of or released by prior owners or operators) or property
contamination (including groundwater contamination), for damages to natural resources and for the costs of
certain health studies. In addition, it is not uncommon for neighboring landowners and other third parties to file
claims for personal injury and property damage allegedly caused by the hazardous substances released into the
environment. In the course of our operations, we use materials that, if released, would be subject to CERCLA
and comparable state statutes. Therefore, governmental agencies or third parties may seek to hold us responsible
under CERCLA and comparable state statutes for all or part of the costs to clean up sites at which such
“hazardous substances” have been released.

Water Discharges. The Federal Water Pollution Control Act of 1972, as amended, also known as the “Clean

Water Act”, the Oil Pollution Act and analogous state laws and regulations promulgated thereunder impose
restrictions and strict controls regarding the unauthorized discharge of pollutants, including produced waters and
other gas and oil wastes, into navigable waters of the United States, as well as state waters. The discharge of
pollutants into regulated waters is prohibited, except in accordance with the terms of a permit issued by the EPA
or the state. Spill prevention, control and countermeasure, or SPCC, plan requirements under federal law require
appropriate containment terms and similar structures to help prevent the contamination of navigable waters in the
event of a petroleum hydrocarbon tank spill, rupture or leak. These laws and regulations also prohibit certain
activity in wetlands unless authorized by a permit issued by the U.S. Army Corps of Engineers. The EPA has
also adopted regulations requiring certain oil and natural gas exploration and production facilities to obtain
individual permits or coverage under general permits for storm water discharges. Costs may be associated with
the treatment of wastewater or developing and implementing storm water pollution prevention plans, as well as
for monitoring and sampling the storm water runoff from certain of our facilities. Some states also maintain
groundwater protection programs that require permits for discharges or operations that may impact groundwater
conditions.

The Oil Pollution Act, or OPA, is the primary federal law for oil spill liability. OPA contains numerous

requirements relating to the prevention of and response to petroleum releases into waters of the United States,
including the requirement that operators of offshore facilities and certain onshore facilities near or crossing
waterways must develop and maintain facility response contingency plans and maintain certain significant levels
of financial assurance to cover potential environmental cleanup and restoration costs. The OPA subjects owners
of facilities to strict, joint and several liability for all containment and cleanup costs and certain other damages
arising from a release, including, but not limited to, the costs of responding to a release of oil to surface waters.

Noncompliance with the Clean Water Act or OPA may result in substantial administrative, civil and

criminal penalties, as well as injunctive obligations. We believe we are in material compliance with the
requirements of each of these laws.

Air Emissions. The Federal Clean Air Act, as amended, and comparable state laws and regulations, regulate
emissions of various air pollutants through the issuance of permits and the imposition of other requirements. The
EPA has developed, and continues to develop, stringent regulations governing emissions of air pollutants at
specified sources. Some of our new facilities will be required to obtain permits before work can begin, permits
may be required for our facilities’ operations, and existing facilities may be required to incur capital costs to
remain in compliance. These laws and regulations may increase the costs of compliance for some facilities we
own or operate, and federal and state regulatory agencies can impose administrative, civil and criminal penalties
for non-compliance with air permits or other requirements of the federal Clean Air Act and associated state laws
and regulations. We believe that we are in substantial compliance with all applicable air emissions regulations

14

and that we hold all necessary and valid construction and operating permits for our operations. Obtaining or
renewing permits has the potential to delay the development of oil and natural gas projects. Our operations may
also soon be affected by rapidly emerging regulation of “green house gases,” such as carbon dioxide and
methane, which are emitted in the course of oil and natural gas exploration and production.

Operational Hazards and Insurance

The oil business involves a variety of operating risks, including the risk of fire, explosions, blow outs, pipe

failures and, in some cases, abnormally high pressure formations which could lead to environmental hazards such
as oil spills, natural gas leaks and the discharge of toxic gases. If any of these should occur, we could incur legal
defense costs and could be required to pay amounts due to injury, loss of life, damage or destruction to property,
natural resources and equipment, pollution or environmental damage, regulatory investigation and penalties and
suspension of operations.

In accordance with what we believe to be industry practice, we maintain insurance against some, but not all,

of the operating risks to which our business is exposed. We insure some, but not all, of our properties for
operational and hurricane related events. We currently have insurance policies that include coverage for general
liability, physical damage to our oil and gas properties, operational control of certain wells, oil pollution, third
party liability, workers compensation and employers’ liability and other coverage. Our insurance coverage
includes deductibles that must be met prior to recovery. Additionally, our insurance is subject to exclusion and
limitations, and there is no assurance that such coverage will fully or adequately protect us against liability from
all potential consequences, damages and losses. Any of these events could cause a significant disruption to our
business. For example, we experienced production interruptions in 2005 and 2006 from Hurricanes Katrina and
Rita and, in 2008, from Hurricanes Gustav and Ike. A loss not fully covered by insurance could have a material
adverse affect on our financial position, results of operations and cash flows.

Currently, we have general liability insurance coverage with an annual aggregate limit of up to $21.0
million which includes environmental impairment coverage for the effects of onshore and offshore pollution on
third parties arising from our operations. For our offshore West Cote Blanche Bay properties, we also have a
$25.0 million property physical damage policy which insures against most operational perils, such as explosions,
fire, vandalism, theft, hail and windstorms, provided, however, that this policy is limited to $10.0 million for
damages arising as a result of a named windstorm. In the event of a loss under this policy, we have up to $6.6
million of business interruption coverage available after a 90 day waiting period. All of our insurance coverage
includes deductibles of up to $500,000 per occurrence ($1.5 million in the case of a named windstorm) that must
be met prior to recovery. Additionally, our insurance is subject to customary exclusions and limitations. We
reevaluate the purchase of insurance, policy terms and limits annually each May. Future insurance coverage for
our industry could increase in cost and may include higher deductibles or retentions. In addition, some forms of
insurance may become unavailable in the future or unavailable on terms that we believe are economically
acceptable. No assurance can be given that we will be able to maintain insurance in the future at rates that we
consider reasonable and we may elect to maintain minimal or no insurance coverage. We may not be able to
secure additional insurance or bonding that might be required by new governmental regulations. This may cause
us to restrict our operations, which might severely impact our financial position. The occurrence of a significant
event, not fully insured against, could have a material adverse effect on our financial condition and results of
operations.

At the depths and in the areas in which we operate, and in light of the vertical and directional drilling that

we undertake, we typically do not encounter high pressures or extreme drilling conditions. Accordingly, we
typically do not carry a control of well policy, although we currently have such coverage in place for two specific
wells we are drilling this year. We also require all of our third party vendors to sign master service agreements in
which they agree to indemnify us for injuries and deaths of the service provider’s employees as well as
contractors and subcontractors hired by the service provider.

We have prepared and have in place spill prevention control and countermeasure plans for each of our
principal facilities at WCBB in response to federal and state requirements. The plans are reviewed annually and

15

updated as necessary. As required by applicable regulations, our facilities are built with oil containment features
and we own certain oil containment equipment, such as oil boom to surround drill sites and production facilities
if needed. In addition, we have a national emergency response company on retainer. This company specializes in
the clean up of hydrocarbons as a result of spills, blow-outs and natural disasters. This emergency response
company has been involved in the clean up efforts of some of the largest oil spills along the Gulf Coast and is on
call to us 24 hours a day when its services are needed. It reports that it currently owns over 164 response
vehicles, 65 response vessels, 116 response trailers equipped with decontaminant supplies, personal protective
equipment and other equipment used in responding to oil spills, two storage barge sets, allowing for storage of up
to 248 barrels of recovered oil each, and over 20 roll-off boxes and vacuum boxes. We pay this company a
retainer plus additional amounts when it provides us with clean up services. Our aggregate payments for the
retainer and clean up services during 2009 and 2010 were approximately $139,000. While this company has been
able to meet our service needs when required from time to time in the past, it is possible that its ability to provide
services to us in the future, if and when needed, could be hindered or delayed in the event of a widespread
disaster. However, in light of the depths and the areas in which we operate, and the necessity for gas lift to
produce our WCBB wells due to low reservoir pressure at our WCBB field, we believe other companies would
be available to us in the event our primary remediation company was unable to perform.

Headquarters and Other Facilities

We own an approximately 28,500 square foot office building in Oklahoma City, Oklahoma that serves as
our corporate headquarters. We lease a portion of this office space to certain of our affiliates. We also own an
approximately 12,500 square foot building in Lafayette, Louisiana that is leased to an unrelated third party. This
building contains approximately 6,200 square feet of finished office area and 6,300 square feet of clear span
warehouse area. We also lease 3,722 square feet in a building in Lafayette that we use as our Louisiana
headquarters. Each of these properties is suitable and adequate for its use.

Employees

At December 31, 2010, we had 45 employees. Certain of our employees perform management and

administrative services for affiliated companies. We are reimbursed by these affiliates for the salaries and
benefits of these individuals based on the estimated time they spent working for those affiliates. In addition, in
the past, we have also received 100% of the COPAS overhead charges billed to these affiliated companies. For
the years ended December 31, 2009 and 2008, expenses reimbursed to us under these arrangements were $0.6
million and $1.4 million, respectively, and are reflected as a reduction in our general and administrative
expenses. No amounts were reimbursed to us under these arrangements in 2010. A Louisiana well servicing
company provides all necessary field personnel needed to operate the WCBB and the Hackberry fields.

ITEM 1A. RISK FACTORS

Risks Related to Our Business and Industry

The volatility of oil and natural gas prices due to factors beyond our control greatly affects our profitability.

Our revenues, operating results, profitability, future rate of growth and the carrying value of our oil and
natural gas properties depend primarily upon the prevailing prices for oil and natural gas. Historically, oil and
natural gas prices have been volatile and are subject to fluctuations in response to changes in supply and demand,
market uncertainty and a variety of additional factors that are beyond our control, including:

• worldwide and domestic supplies of oil and natural gas;

•

•

•

the level of prices, and expectations about future prices, of oil and natural gas;

the cost of exploring for, developing, producing and delivering oil and natural gas;

the expected rates of declining current production;

• weather conditions, including hurricanes, that can affect oil and natural gas operations over a wide area;

•

•

•

•

•

•

•

•

•

•

the level of consumer demand;

the price and availability of alternative fuels;

technical advances affecting energy consumption;

risks associated with operating drilling rigs;

the availability of pipeline capacity;

the price and level of foreign imports;

domestic and foreign governmental regulations and taxes;

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

political instability or armed conflict in oil and natural gas producing regions; and

the overall economic environment.

These factors and the volatility of the energy markets make it extremely difficult to predict future oil and

natural gas price movements with any certainty. For example, during the past five years, the West Texas
Intermediate posted price for crude oil has ranged from a low of $30.28 per barrel, or bbl, in December 2008 to a
high of $145.31 per bbl in July 2008. The Henry Hub spot market price of natural gas has ranged from a low of
$1.83 per million British thermal units, or MMBtu, in September 2009 to a high of $15.52 per MMBtu in January
2006. On March 7, 2011, the West Texas Intermediate posted price for crude oil was $105.44 per bbl and the
Henry Hub spot market price of natural gas was $3.93 per MMBtu. Any substantial decline in the price of oil and
natural gas will likely have a material adverse effect on our operations, financial condition and level of
expenditures for the development of our oil and natural gas reserves, and may result in write downs of oil and
natural gas properties due to ceiling test limitations.

Declining general economic, business or industry conditions may have a material adverse effect on our results of
operations, liquidity and financial condition.

Concerns over global economic conditions, energy costs, geopolitical issues, the availability and cost of
credit, the United States mortgage market and a declining real estate market in the United States have contributed
to increased economic uncertainty and diminished expectations for the global economy. These factors, combined
with volatile prices of oil, natural gas and natural gas liquids, declining business and consumer confidence and
increased unemployment, have precipitated an economic slowdown and a recession. Concerns about global
economic growth have had a significant adverse impact on global financial markets and commodity prices. If the

17

economic climate in the United States or abroad continues to deteriorate, demand for petroleum products could
continue to diminish, which could impact the price at which we can sell our oil, natural gas and natural gas
liquids, affect our vendors, suppliers and customers ability to continue operations, and ultimately adversely
impact our results of operations, liquidity and financial condition.

Our success depends on finding, developing or acquiring additional reserves.

Our future success depends 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 undertake development, exploration and other
replacement activities or use third parties to accomplish these activities. We have made and expect to make in the
future substantial capital expenditures in our business and operations for the development, production, exploration
and acquisition of oil and natural gas reserves. To date, we have financed capital expenditures primarily with cash
flow from operations, the issuance of equity securities and borrowings under our bank and other credit facilities.
Our cash flow from operations and access to capital are subject to a number of variables, including:

•

•

•

•

our proved reserves;

the level of oil and natural gas we are able to produce from existing wells;

the prices at which oil and natural gas are sold; and

our ability to acquire, locate and produce new reserves.

We may not have sufficient resources to undertake our exploration, development and production activities

or the acquisition of oil and natural gas reserves, our exploratory projects or other replacement activities may not
result in significant additional reserves and we may not have success drilling productive wells at low finding and
development costs. Furthermore, although our revenues may increase if prevailing oil and natural gas prices
increase significantly, our finding costs for additional reserves could also increase.

Our failure to successfully identify, complete and integrate future acquisitions of properties or businesses could
reduce our earnings and slow our growth.

There is intense competition for acquisition opportunities in our industry. Competition for acquisitions may
increase the cost of, or cause us to refrain from, completing acquisitions. Our ability to complete acquisitions is
dependent upon, among other things, our ability to obtain debt and equity financing and, in some cases,
regulatory approvals. Further, these acquisitions may be in geographic regions in which we do not currently
operate, which could result in unforeseen operating difficulties and difficulties in coordinating geographically
dispersed operations, personnel and facilities. In addition, if we enter into new geographic markets, we may be
subject to additional and unfamiliar legal and regulatory requirements. Compliance with regulatory requirements
may impose substantial additional obligations on us and our management, cause us to expend additional time and
resources in compliance activities and increase our exposure to penalties or fines for non-compliance with such
additional legal requirements. Completed acquisitions could require us to invest further in operational, financial
and management information systems and to attract, retain, motivate and effectively manage additional
employees. The inability to effectively manage the integration of acquisitions could reduce our focus on
subsequent acquisitions and current operations, which, in turn, could negatively impact our earnings and growth.
Our financial position and results of operations may fluctuate significantly from period to period, based on
whether or not significant acquisitions are completed in particular periods.

Our Canadian oil sands project is a complex undertaking and may not be completed at our estimated cost or at
all.

During the third quarter of 2006, we, through our wholly-owned subsidiary Grizzly Holdings Inc.,
purchased a 24.9% interest in Grizzly. The remaining interests in Grizzly are owned by entities controlled by

18

Wexford. During 2006 and 2007, Grizzly acquired leases in the Athabasca region located in the Alberta Province
near Fort McMurray near other oil sands development projects. Grizzly has approximately 534,000 acres under
lease and our total net investment in Grizzly was approximately $46.5 million, including a note receivable of
$20.0 million, at December 31, 2010. To date, Grizzly has drilled an aggregate of 199 core holes and three water
supply test wells, tested nine separate lease blocks and conducted a seismic program and expects to drill an
additional three core locations during the remainder of the 2010/2011 winter delineation drilling season. In 2010,
Grizzly filed applications in Alberta, Canada for the development of an 11,300 barrel per day oil sand SAGD
facility at Algar Lake. Grizzly expects regulatory approval by mid-2011, followed by an anticipated construction
period of 18 months leading to first production. The cost of this initial facility is currently estimated to be
approximately $120.0 million. This is a complex project and financing has not been secured. This project may
not be completed at our estimated cost or at all.

Shortage of rigs, equipment, raw materials, supplies or personnel may restrict our operations.

The oil and natural gas industry is cyclical, which can result in shortages of drilling rigs, equipment, raw
materials (particularly sand and other proppants), supplies and personnel. When shortages occur, the costs and
delivery times of rigs, equipment and supplies increase and demand for, and wage rates of, qualified drilling rig
crews also rise with increases in the number of active rigs in service. In accordance with customary industry
practice, we rely on independent third party service providers to provide most of the services necessary to drill
new wells. Shortages of drilling rigs, equipment, raw materials (particularly sand and other proppants), supplies,
personnel, trucking services, tubulars, fracing and completion services and production equipment could delay or
restrict our exploration and development operations, which in turn could impair our financial condition and
results of operations.

We rely on a few key employees whose absence or loss could disrupt our operations resulting in a loss of
revenues.

Many key responsibilities within our business have been assigned to a small number of employees. The loss

of their services, particularly the loss of Mike Liddell, our Chairman of the Board, James D. Palm, our Chief
Executive Officer, Michael G. Moore, our Chief Financial Officer, or our two geophysicists could disrupt our
operations resulting in a loss of revenues. We do not have an employment contract with any of our executives,
with the exception of Mr. Liddell’s written employment agreement and Mr. Palm’s oral employment agreement,
and our executives are not restricted from competing with us if they cease to be employed by us. Additionally, as
a practical matter, any employment agreement we may enter into will not assure the retention of our employees.
In addition, we do not maintain “key person” life insurance policies on any of our employees. As a result, we are
not insured against any losses resulting from the death of our key employees.

Our proved reserves and related PV-10 as of December 31, 2010 have been reported under SEC rules that went
into effect on January 1, 2010. The estimates provided in accordance with these SEC rules may change
materially as a result of interpretive guidance that may be released by the SEC.

We have included in this report certain estimates of our proved reserves and related PV-10 at December 31,

2010 as prepared consistent with our and our independent reserve engineers’ interpretations of the SEC rules
relating to disclosures of estimated natural gas and oil reserves. These rules require SEC reporting companies to
prepare their reserve estimates using revised reserve definitions and revised pricing based on 12-month
unweighted first-day-of-the-month average pricing. The SEC has released only limited interpretive guidance
regarding reporting of reserve estimates under these rules. Accordingly, while the estimates of our proved
reserves and related PV-10 at December 31, 2010 included in this report have been prepared based on what we
and our independent reserve engineers believe to be reasonable interpretations of the SEC rules, those estimates
could differ materially from any estimates we might prepare applying more specific SEC interpretive guidance.

19

We may be limited in our ability to book additional proved undeveloped reserves under the recent SEC rules.

One of the impacts of the recent SEC reserve rules is a general requirement that, subject to limited
exceptions, proved undeveloped reserves may only be booked if they relate to wells scheduled to be drilled
within five years of the date of booking. This rule may limit our potential to book additional proved undeveloped
reserves as we pursue our drilling program.

Estimates of oil and natural gas reserves are uncertain and may vary substantially from actual production.

There are numerous uncertainties associated with estimating quantities of proved reserves and in projecting
future rates of production and timing of expenditures. The reserve information included in this report represents
only estimates based on reports as of December 31, 2010 prepared by Netherland, Sewell & Associates, Inc., or
NSAI, with respect to our WCBB and Niobrara fields, by Pinnacle Energy Services, LLC, or Pinnacle, with
respect to our assets in the Permian Basin in West Texas and by our personnel with respect to our Hackberry
fields and our overriding royalty and non-operated interests. Petroleum engineering is not an exact science.
Information relating to our proved oil and natural gas reserves is based upon engineering estimates. Estimates of
economically recoverable oil and natural gas reserves and of future net cash flows necessarily depend upon a
number of variable factors and assumptions, such as historical production from the area compared with
production from other producing areas, future site restoration and abandonment costs, the assumed effects of
regulations by governmental agencies and assumptions concerning future oil and natural gas prices, future
operating costs, severance and excise taxes, capital expenditures and workover and remedial costs, all of which
may in fact vary considerably from actual results. For these reasons, estimates of the economically recoverable
quantities of oil and natural gas attributable to any particular group of properties, classifications of such reserves
based on risk of recovery and estimates of the future net cash flows expected therefrom prepared by different
engineers or by the same engineers at different times may vary substantially. Actual production, revenues and
expenditures with respect to our reserves will likely vary from estimates, and such variances may be material.

Estimates of reserves as of year-end 2010 and 2009 were prepared using an average price equal to the
unweighted arithmetic average of hydrocarbon prices received on a field-by-field basis on the first day of each
month within the 12-month period ended December 31, 2010 and 2009, respectively, in accordance with the
revised guidelines of the SEC applicable to reserves estimates for such years. Estimates of reserves as of
year-end 2008 were prepared using constant prices and costs in accordance with previous guidelines of the SEC
based on hydrocarbon prices received on a field-by-field basis as of December 31st of such year. Reserve
estimates do not include any value for probable or possible reserves that may exist, nor do they include any value
for undeveloped acreage. The reserve estimates represent our net revenue interest in our properties.

The present value of future net revenues from our proved reserves is not necessarily the same as the current
market value of our estimated oil and natural gas reserves. We base the estimated discounted future net revenue
from our proved reserves for 2010 and 2009 on average price equal to the unweighted average of prices received
on a field-by-field basis on the first day of each month within the 12-month period ended December 31, 2010 and
2009, respectively, in accordance with the revised guidelines of the SEC applicable to reserves estimates for such
years. Estimated discounted future net revenue from reserves as of year-end 2008 were prepared using constant
prices and costs in accordance with previous guidelines of the SEC as of December 31st of such year. However,
actual future net revenues from our oil and natural gas properties also will be affected by factors such as:

•

•

•

•

actual prices we receive for oil and natural gas;

the amount and timing of actual production;

supply of and demand for oil and natural gas; and

changes in governmental regulations or taxation.

The timing of both our production and our incurrence of costs in connection with the development and
production of oil and natural gas properties will affect the timing of actual future net revenues from proved

20

reserves, and thus their actual present value. In addition, the 10% discount factor we use when calculating
discounted future net cash flows may not be the most appropriate discount factor based on interest rates in effect
from time to time and risks associated with us or the oil and natural gas industry in general.

As of December 31, 2010, approximately 63% of our estimated proved reserves were undeveloped.
Recovery of undeveloped reserves requires significant capital expenditures and may require successful drilling
operations. The reserve data assumes that we can and will make these expenditures and conduct these operations
successfully, but these assumptions may not be accurate, and this may not occur.

There are numerous uncertainties in estimating quantities of bitumen reserves and resources and the indicated
level of reserves or recovery of bitumen may not be realized.

There are numerous uncertainties in estimating quantities of bitumen reserves and resources, and the
indicated level of reserves or recovery of bitumen may not be realized. In general, estimates of economically
recoverable bitumen reserves and the future net cash flow from such reserves are based upon a number of factors
and assumptions made as of the date on which the reserve and resource estimates were determined, such as
geological and engineering estimates which have uncertainties, the assumed effects of regulation by
governmental agencies and estimates of future commodity prices and operating costs, all of which may vary
considerably from actual results. All such estimates are, to some degree, uncertain and classifications of reserves
are only attempts to define the degree of uncertainty involved. For these reasons, estimates of the economically
recoverable bitumen, the classification of such reserves based on risk of recovery and estimates of future net
revenues expected therefrom, prepared by different engineers or by the same engineers at different times, may
vary substantially.

Estimates with respect to reserves and resources that may be developed and produced in the future are often

based upon volumetric calculations and upon analogy to similar types of reserves, rather than upon actual
production history. Estimates based on these methods generally are less reliable than those based on actual
production history. Subsequent evaluation of the same reserves based upon production history may result in
variations in the estimated reserves. Reserve and resource estimates may require revision based on actual
production experience. Reserve and resources estimates are determined with reference to assumed oil prices and
operating costs. Market price fluctuations of oil prices may render uneconomic the recovery of certain grades of
bitumen. The actual gravity or quality of bitumen to be produced from Grizzly’s lands cannot be determined at
this time.

The marketability of our production is dependent upon compressors, gathering lines, transportation barges and
other facilities, certain of which we do not control. When these facilities are unavailable, our operations can be
interrupted and our revenues reduced.

The marketability of our oil and natural gas production depends in part upon the availability, proximity and
capacity of natural gas lines and transportation barges owned by third parties. In general, we do not control these
transportation facilities and our access to them may be limited or denied. A significant disruption in the
availability of these transportation facilities or our compression and other production facilities could adversely
impact our ability to deliver to market or produce our oil and natural gas and thereby cause a significant
interruption in our operations. We are at particular risk with respect to oil and natural gas produced at our WCBB
field, which is our largest field. In October 2006, for example, a natural gas line in this field operated by our
natural gas purchaser was ruptured by a third party contractor, requiring the field to be shut in for approximately
seven weeks until the line could be repaired. Further, we are dependent on our oil purchaser to provide the barges
necessary to transport our oil production from the WCBB field. If, in the future, we are unable, for any sustained
period, to implement acceptable delivery or transportation arrangements or encounter compression or other
production related difficulties, we will be required to again shut in or curtail production from the field. Any such
shut in or curtailment, or an inability to obtain favorable terms for delivery of the oil and natural gas produced
from the field, would adversely affect our financial condition and results of operations.

21

A substantial portion of our producing properties is located in Louisiana, making us vulnerable to risks
associated with operating in this region.

Our largest field by production, WCBB, is located approximately five miles off the coast of Louisiana in a
shallow bay with water depths averaging eight to ten feet. As a result, we may be disproportionately exposed to
the impact of delays or interruptions of production from this region caused by weather conditions such as fog or
rain, hurricanes or other natural disasters or lack of field infrastructure. Losses could occur for uninsured risks or
in amounts in excess of any existing insurance coverage. We may not be able to obtain and maintain adequate
insurance at rates we consider reasonable or that any particular types of coverage will be available.

Our identified drilling locations, which are part of our anticipated future drilling plans, are susceptible to
uncertainties that could materially alter the occurrence or timing of their drilling.

We have identified over 600 drilling locations on our Louisiana, West Texas and Colorado properties. These

drilling locations represent a significant part of our growth strategy. Our ability to drill and develop these
locations depends on a number of uncertainties, including the availability of capital, oil and natural gas prices,
inclement weather, costs, drilling results and regulatory changes. Because of these uncertainties, we do not know
if the numerous potential drilling locations we have identified will ever be drilled or if we will be able to produce
oil or natural gas from these or any other potential drilling locations. As such, our actual drilling activities may
materially differ from those presently identified, which could adversely affect our business.

Operating hazards and uninsured risks may result in substantial losses.

Our operations are subject to all of the hazards and operating risks associated with drilling for and
production of oil and natural gas, including the risk of fire, explosions, blowouts, pipe failure, abnormally
pressured formations and environmental hazards such as oil spills, gas leaks, ruptures or discharges of toxic
gases. The occurrence of any of these events could result in substantial losses to us due to injury or loss of life,
severe damage to or destruction of property, natural resources and equipment, pollution or other environmental
damage, clean-up responsibilities, regulatory investigation and penalties and suspension of operations. For
example, in October 2006, an accident occurred north of our production facilities in the WCBB field in southern
Louisiana involving two contracted vessels that were performing work on our behalf in the field. A tugboat and
two barges laden with construction materials ruptured an underwater natural gas pipeline and a subsequent fire
damaged the vessels. Four confirmed fatalities resulted from the accident. Several lawsuits relating to this
incident were filed against us, among other parties. These lawsuits against us have all been settled.

In accordance with what we believe to be customary industry practice, we historically have maintained
insurance against some, but not all, of our business risks. Our insurance may not be adequate to cover any losses
or liabilities we may suffer. Also, insurance may no longer be available to us or, if it is, its availability may be at
premium levels that do not justify its purchase. In addition, we understand that insurance carriers are modifying
or otherwise restricting insurance coverage or ceasing to provide certain types of insurance coverage in the Gulf
Coast region. We may not be able to secure additional insurance of bonding that might be required by new
governmental regulations. This may cause us to restrict our operations, which might severely impact our
financial position. We may also be liable for environmental damage caused by previous owners of properties
purchased by us, which liabilities may not be covered by insurance.

Our operations are subject to various governmental regulations which require compliance that can be
burdensome and expensive.

Our oil and natural gas operations are subject to various federal, state and local governmental regulations

that may be changed from time to time in response to economic and political conditions. Matters subject to
regulation include discharge permits for drilling operations, drilling bonds, reports concerning operations, the
spacing of wells, unitization and pooling of properties and taxation. From time to time, regulatory agencies have
imposed price controls and limitations on production by restricting the rate of flow of oil and natural gas wells

22

below actual production capacity to conserve supplies of oil and gas. In addition, the production, handling,
storage, transportation, remediation, emission and disposal of oil and gas, by-products thereof and other
substances and materials produced or used in connection with oil and natural gas operations are subject to
regulation under federal, state and local laws and regulations primarily relating to protection of human health and
the environment. Failure to comply with these laws and regulations may result in the assessment of sanctions,
including administrative, civil or criminal penalties, permit revocations and injunctions limiting or prohibiting
some or all of our operations. Moreover, these laws and regulations have continually imposed increasingly strict
requirements for water and air pollution control and solid waste management. Significant expenditures may be
required to comply with governmental laws and regulations applicable to us. We believe the trend of more
expansive and stricter environmental legislation and regulations will continue.

Federal and state legislation and regulatory initiatives relating to hydraulic fracturing could result in increased
costs and additional operating restrictions or delays.

Hydraulic fracturing is an important and common practice that is used to stimulate production of

hydrocarbons, particularly natural gas, from tight formations, including shales. The process involves the injection
of water, sand and chemicals under pressure into formations to fracture the surrounding rock and stimulate
production. The process is typically regulated by state oil and gas commissions. However, the EPA recently
asserted federal regulatory authority over hydraulic fracturing involving diesel additives under the federal Safe
Drinking Water Act’s Underground Injection Program. While the EPA has yet to take any action enforce or
implement this newly asserted regulatory authority, industry groups have filed suit challenging the EPA’s recent
decision. At the same time, the EPA has commenced a study of the potential environmental impacts of hydraulic
fracturing activities, with results of the study anticipated to be available by late 2012, and a committee of the
U.S. House of Representatives is also conducting an investigation of hydraulic fracturing practices. In addition,
legislation was proposed in the recently ended 111th session of Congress to provide for federal regulation of
hydraulic fracturing and to require disclosure of the chemicals used in the fracturing process, and such legislation
could be introduced in the current session of Congress. Also, some states have adopted, and other states are
considering adopting, regulations that could restrict hydraulic fracturing in certain circumstances or otherwise
require the public disclose of chemicals used in the hydraulic fracturing process. On March 1, 2011 a bill was
introduced in the Texas Senate that would require the Railroad Commission of Texas to adopt rules requiring
owners and operators of wells on which hydraulic fracturing activities been performed or other persons who had
performed such activities to provide the agency written information on, among other things, the chemicals used
in such activities. If new laws or regulations that significantly restrict hydraulic fracturing are adopted, such laws
could make it more difficult or costly for us to drill and produce from tight formations as well as make it easier
for third parties opposing the hydraulic fracturing process to initiate legal proceedings. In addition, if hydraulic
fracturing is regulated at the federal level, fracturing activities could become subject to additional permitting and
financial assurance requirements, more stringent construction specifications, increased monitoring, reporting and
recordkeeping obligations, plugging and abandonment requirements and also to attendant permitting delays and
potential increases in costs. Such legislative changes could cause us to incur substantial compliance costs, and
compliance or the consequences of any failure to comply by us could have a material adverse effect on our
financial condition and results of operations. At this time, it is not possible to estimate the potential impact on our
business that may arise if federal or state legislation governing hydraulic fracturing is enacted into law.

The recent adoption of derivatives legislation by the U.S. Congress could have an adverse effect on our ability to
use derivative instruments to reduce the effect of commodity price, interest rate and other risks associated with
our business.

The recent adoption of derivatives legislation by the U.S. Congress could have an adverse effect on our

ability to use derivative instruments to reduce the effect of commodity price, interest rate and other risks
associated with our business. The U.S. Congress recently adopted the Dodd-Frank Wall Street Reform and
Consumer Protection Act (HR 4173), which, among other provisions, establishes federal oversight and regulation
of the over-the-counter derivatives market and entities that participate in that market. The new legislation was

23

signed into law by the President on July 21, 2010, and requires the Commodities Futures Trading Commission,
or CFTC, and the SEC to promulgate rules and regulations implementing the new legislation within 360 days
from the date of enactment. In its rulemaking under the new legislation, the CFTC has proposed regulations to set
position limits for certain futures and option contracts in the major energy markets and for swaps that are their
economic equivalents. Certain bona fide hedging transactions or positions would be exempt from these position
limits. It is not possible at this time to predict when the CFTC will finalize these regulations. The financial
reform legislation may also require us to comply with margin requirements and with certain clearing and trade-
execution requirements in connection with our existing or future derivative activities, although the application of
those provisions to us is uncertain at this time. The financial reform legislation may also require the
counterparties to our derivative instruments to spin off some of their derivatives activities to separate entities,
which may not be as creditworthy as the current counterparties. The new legislation and any new regulations
could significantly increase the cost of derivative contracts (including through requirements to post collateral
which could adversely affect our available liquidity), materially alter the terms of derivative contracts, reduce the
availability of derivatives to protect against risks we encounter, reduce our ability to monetize or restructure our
derivative contracts in existence at that time, and increase our exposure to less creditworthy counterparties. If we
reduce or change the way we use derivative instruments as a result of the legislation and regulations, our results
of operations may become more volatile and its cash flows may be less predictable, which could adversely affect
our ability to plan for and fund capital expenditures. Finally, the legislation was intended, in part, to reduce the
volatility of oil and natural gas prices, which some legislators attributed to speculative trading in derivatives and
commodity instruments related to oil and natural gas. Our revenues could therefore be adversely affected if a
consequence of the legislation and regulations is to lower commodity prices. Any of these consequences could
have a material adverse effect on our consolidated financial position, results of operations or cash flows.

The proposed changes to U.S. tax laws, if adopted, could have an adverse effect on our business, financial
condition, results of operations and cash flows.

The U.S. President’s Fiscal Year 2012 Budget Proposal includes provisions that would, if enacted, make
significant changes to U.S. tax laws. These changes include, but are not limited to, (i) eliminating the immediate
deduction for intangible drilling and development costs, (ii) eliminating the deduction from income for domestic
production activities relating to oil and natural gas exploration and development, and (iii) implementing certain
international tax reforms. These proposed changes in the U.S. tax laws, if adopted, could adversely affect our
business, financial condition, results of operations and cash flows.

The adoption of climate change legislation by Congress could result in increased operating costs and reduced
demand for the oil and natural gas we produce.

Many nations have agreed to limit emissions of “greenhouse gases” pursuant to the United Nations

Framework Convention on Climate Change, also known as the “Kyoto Protocol.” Methane, a primary component
of natural gas, and carbon dioxide, a byproduct of the burning of oil, natural gas, and refined petroleum products,
are “greenhouse gases,” or GHGs, regulated by the Kyoto Protocol. Although the United States is not
participating in the Kyoto Protocol at this time, several states or geographic regions have adopted legislation and
regulations to reduce emissions of greenhouse gases. Additionally, on April 2, 2007, the U.S. Supreme Court
ruled, in Massachusetts, et al. v. EPA, that the EPA has the authority to regulate carbon dioxide emissions from
automobiles as “air pollutant” under the federal Clean Air Act. Thereafter, in December 2009, the EPA
determined that emissions of carbon dioxide, methane and other GHGs present an endangerment to public health
and the environment because, according to the EPA, emissions of such gases contribute to warming of the earth’s
atmosphere and other climatic changes. These findings by the EPA allowed the agency to proceed with the
adoption and implementation of regulations that would restrict emissions of GHGs under existing provisions of
the federal Clean Air Act. Subsequently, the EPA adopted two sets of related rules, one of which purports to
regulate emissions of GHGs from motor vehicles and the other of which regulates emissions of GHGs from
certain large stationary sources of emissions such as power plants or industrial facilities. The EPA finalized the
motor vehicle rule in April 2010 and it became effective January 2011, although it does not require immediate
reductions in GHG emissions. The EPA adopted the stationary source rule in May 2010, and it also became

24

effective January 2011, although it remains subject of several pending lawsuits filed by industry groups.
Additionally, in September 2009, the EPA issued a final rule requiring the reporting of GHG emissions from
specified large GHG emission sources in the U.S., including natural gas liquids fractionators and local natural
gas/distribution companies, beginning in 2011 for emissions occurring in 2010. More recently, in November
2010, the EPA expanded its existing GHG reporting rule to include onshore and offshore oil and natural gas
production and onshore processing, transmission, storage, and distribution facilities, which may include certain
of our facilities, beginning in 2012 for emissions occurring in 2011.

In June 2009, the U.S. House of Representatives passed the American Clean Energy and Security (ACES)

Act that, among other things, would have established a cap-and-trade system to regulate greenhouse gas
emissions and would have required an 80% reduction in GHG emissions from sources within the United States
between 2012 and 2050. The ACES Act did not pass the Senate, however, and so was not enacted by the 111th
Congress. The United States Congress is likely to again consider a climate change bill in the future. Moreover,
almost half of the states have already taken legal measures to reduce emissions of GHGs, primarily through the
planned development of GHG emission inventories and/or regional GHG cap and trade programs. Most of these
cap and trade programs work by requiring major sources of emissions, such as electric power plants, or major
producers of fuels, such as refineries and gas processing plants, to acquire and surrender emission allowances
corresponding with their annual emissions of GHGs. The number of allowances available for purchase is reduced
each year until the overall GHG emission reduction goal is achieved. As the number of GHG emission
allowances declines each year, the cost or value of allowances is expected to escalate significantly. Restrictions
on emissions of methane or carbon dioxide that may be imposed in various states could adversely affect the oil
and natural gas industry. Currently, while we are subject to certain federal GHG monitoring and reporting
requirements our operations are not adversely impacted by existing federal, state and local climate change
initiatives and, at this time, it is not possible to accurately estimate how potential future laws or regulations
addressing greenhouse gas emissions would impact our business.

Any failure by us to comply with applicable environmental laws and regulations may result in governmental

authorities taking actions that could adversely impact our operations and financial condition, including the:

•

•

•

•

•

issuance of administrative, civil and criminal penalties;

denial, suspension or revocation of necessary permits, licenses or other authorizations;

imposition of injunctive obligations or limitations on our operations;

requirement for additional pollution controls; and

required performance of site investigatory, remedial or other corrective actions.

In addition, there has been public discussion that climate change may be associated with extreme weather
conditions such as more intense hurricanes, thunderstorms, tornados and snow or ice storms, as well as rising sea
levels. Another possible consequence of climate change is increased volatility in seasonal temperatures. Some
studies indicate that climate change could cause some areas to experience temperatures substantially colder than
their historical averages. Extreme weather conditions can interfere with our production and increase our costs and
damage resulting from extreme weather may not be fully insured. However, at this time, we are unable to
determine the extent to which climate change may lead to increased storm or weather hazards affecting our
operations.

We face extensive competition in our industry.

The oil and natural gas industry is intensely competitive, and we compete with other companies that have
greater resources. Many of these companies not only explore for and produce oil and natural gas, but also carry
on midstream and refining operations and market petroleum and other products on a regional, national or
worldwide basis. These competitors may be better positioned to take advantage of industry opportunities and to
withstand changes affecting the industry, such as fluctuations in oil and natural gas prices and production, the
availability of alternative energy sources and the application of government regulation.

25

We depend upon two customers for the sale of most of our oil and natural gas production.

The availability of a ready market for any oil and/or natural gas we produce depends on numerous factors

beyond the control of our management, including but not limited to the extent of domestic production and
imports of oil, the proximity and capacity of gas pipelines, the availability of skilled labor, materials and
equipment, the effect of state and federal regulation of oil and natural gas production and federal regulation of
gas sold in interstate commerce. The oil and natural gas we produce in Louisiana is sold to purchasers who
service the areas where our wells are located. We sell the majority of our oil to Shell Trading Company, or Shell.
Shell takes custody of the oil at the outlet from our oil storage barge. Our production from WCBB, other than the
production sold under forward sales contracts, is being sold in accordance with the Shell posted price for West
Texas/New Mexico Intermediate crude plus or minus Platt’s trade month average P+ value, plus or minus the
Platt’s HLS/WTI differential less $2.70 per barrel for transportation. During 2010, we sold 75% and 19% of our
oil production to Shell and Windsor Energy Group, LLC, or Windsor, respectively and 50%, 32%, and 10% of
our natural gas production to Windsor, Chevron and Hilcorp Energy Company, respectively. During 2009, we
sold 92% and 7% of our oil production to Shell and Windsor, respectively, and 45%, 38%, and 16% of our
natural gas production to Windsor, Chevron and Hilcorp Energy Company, respectively. During 2008, we sold
87% of our oil production to Shell and 11% to Windsor, 100% of our natural gas liquids production to Windsor,
and 60%, 22%, and 16% of our natural gas production to Chevron, Windsor, and Hilcorp Energy Company,
respectively. We may not continue to have ready access to suitable markets for our future oil and natural gas
production.

Our method of accounting for oil and natural gas properties may result in impairment of asset value.

We use the full cost method of accounting for oil and natural gas operations. Accordingly, all costs,

including nonproductive costs and certain general and administrative costs associated with acquisition,
exploration and development of oil and natural gas properties, are capitalized. Net capitalized costs are limited to
the estimated future net revenues, after income taxes, discounted at 10% per year, from proven oil and natural
gas reserves and the cost of the properties not subject to amortization. Such capitalized costs, including the
estimated future development costs and site remediation costs, if any, are depleted by an equivalent
units-of-production method, converting gas to barrels at the ratio of six Mcf of gas to one barrel of oil.

Companies that use the full cost method of accounting for oil and gas properties are required to perform a
ceiling test each quarter. The test determines a limit, or ceiling, on the book value of the oil and gas properties.
Net capitalized costs are limited to the lower of unamortized cost net of deferred income taxes or the cost center
ceiling. The cost center ceiling is defined as the sum of (a) estimated future net revenues, discounted at 10% per
annum, from proved reserves, based on the 12-month unweighted average of the first-day-of-the-month prices for
2010 and 2009 and prior to 2009, unescalated year-end prices, adjusted for any contract provisions or financial
derivatives, if any, that hedge oil and natural gas revenue, and excluding the estimated abandonment costs for
properties with asset retirement obligations recorded on the balance sheet, (b) the cost of properties not being
amortized, if any, and (c) the lower of cost or market value of unproved properties included in the cost being
amortized, less income tax effects related to differences between the book and tax basis of the oil and natural gas
properties. If the net book value reduced by the related net deferred income tax liability exceeds the ceiling, an
impairment or noncash writedown is required. A ceiling test impairment can give us a significant loss for a
particular period. Once incurred, a write down of oil and natural gas properties is not reversible at a later date,
even if oil or gas prices increase. If prices of oil, natural gas and natural gas liquids decrease, we may be required
to further write down the value of our oil and gas properties. Future non-cash asset impairments could negatively
affect our results of operations.

Our use of 2-D and 3-D seismic data is subject to interpretation and may not accurately identify the presence of
oil and natural gas, which could adversely affect the results of our drilling operations.

Even when properly used and interpreted, 2-D and 3-D seismic data and visualization techniques are only

tools used to assist geoscientists in identifying subsurface structures and hydrocarbon indicators and do not

26

enable the interpreter to know whether hydrocarbons are, in fact, present in those structures. In addition, the use
of 3-D seismic and other advanced technologies requires greater predrilling expenditures than traditional drilling
strategies, and we could incur losses as a result of such expenditures. As a result, our drilling activities may not
be successful or economical.

We have entered into forward sales contracts and fixed price swaps and may in the future enter into additional
contracts for a portion of our production, which may result in our making cash payments or prevent us from
receiving the full benefit of increases in prices for oil and gas.

To mitigate the effects of commodity price fluctuations, we were party to forward sales contracts for the sale

of 3,000 barrels of WCBB production per day at a weighted average daily price of $54.81 per barrel, before
transportation costs and differentials, for the period January 2010 through February 2010. For the period March
2010 through December 2010, we were party to forward sales contracts for the sale of 2,300 barrels of WCBB
production per day at a weighted average daily price of $58.24 per barrel before transportation costs and
differentials. In November 2010, we entered into fixed price swaps for 2,000 barrels of oil per day at a weighted
average price of $86.96 per barrel, before transportation costs and differentials, for the period January 2011
through December 2011. We delivered approximately 45% of our 2010 production under these agreements.
Under the 2011 contracts, we have committed to deliver approximately 30% to 33% of our estimated 2011
production. Such arrangements may expose us to risk of financial loss in certain circumstances, including
instances where production is less than expected or oil prices increase. In addition, these arrangements may limit
the benefit to us of increases in the price of oil. These forward sales contracts and fixed price swaps are
accounted for as cash flow hedges and recorded at fair value pursuant to FASB ASC 815, “Derivatives and
Hedging,” and related pronouncements.

A terrorist attack or armed conflict could harm our business.

Terrorist activities, anti-terrorist efforts and other armed conflicts involving the United States or other
countries may adversely affect the United States and global economies and could prevent us from meeting our
financial and other obligations. If any of these events occur, the resulting political instability and societal
disruption could reduce overall demand for oil and natural gas, potentially putting downward pressure on demand
for our services and causing a reduction in our revenues. Oil and natural gas related facilities could be direct
targets of terrorist attacks, and our operations could be adversely impacted if infrastructure integral to our
customers’ operations is destroyed or damaged. Costs for insurance and other security may increase as a result of
these threats, and some insurance coverage may become more difficult to obtain, if available at all.

Conservation measures and technological advances could reduce demand for oil and natural gas.

Fuel conservation measures, alternative fuel requirements, increasing consumer demand for alternatives to

oil and natural gas, technological advances in fuel economy and energy generation devices could reduce demand
for oil and natural gas. The impact of the changing demand for oil and gas services and products may have a
material adverse effect on our business, financial condition, results of operations and cash flows.

Risks Related to Our Common Stock

If our quarterly revenues and operating results fluctuate significantly, the price of our common stock may be
volatile.

Our revenues and operating results may in the future vary significantly from quarter to quarter. If our
quarterly results fluctuate, it may cause our stock price to be volatile. We believe that a number of factors could
cause these fluctuations, including:

•

•

changes in oil and natural gas prices;

changes in production levels;

27

•

•

•

•

changes in governmental regulations and taxes;

geopolitical developments;

the level of foreign imports of oil and natural gas; and

conditions in the oil and natural gas industry and the overall economic environment.

Because of the factors listed above, among others, we believe that our quarterly revenues, expenses and
operating results may vary significantly in the future and that period-to-period comparisons of our operating
results are not necessarily meaningful. You should not rely on the results of one quarter as an indication of our
future performance. It is also possible that in some future quarters, our operating results will fall below our
expectations or the expectations of market analysts and investors. If we do not meet these expectations, the price
of our common stock may decline significantly.

Our largest stockholder controls a significant percentage of our common stock, and its interests may conflict
with those of our other stockholders.

As of December 31, 2010, Charles E. Davidson, our largest stockholder, beneficially owned approximately
25.4% of our outstanding common stock. As a result, this stockholder acting alone is able to exercise significant
influence over most matters requiring approval by our stockholders, including the election of directors and the
approval of significant corporate transactions. Such a concentration of ownership may have the effect of delaying
or preventing a change in control of us, including transactions in which stockholders might otherwise receive a
premium for their shares over then current market prices.

We do not currently pay dividends on our common stock and do not anticipate doing so in the future.

We have paid no cash dividends on our common stock, and we may not pay cash dividends on our common

stock in the future. We intend to retain any earnings to fund our operations. Therefore, we do not anticipate
paying any cash dividends on our common stock in the foreseeable future. In addition, the terms of our credit
agreement prohibit the payment of any dividends to the holders of our common stock.

A change of control could limit our use of net operating losses.

As of December 31, 2010, we had a net operating loss, or NOL, carry forward of approximately $52.4
million for federal income tax purposes. Transfers of our stock in the future could result in an ownership change.
In such a case, our ability to use the NOLs generated through the ownership change date could be limited. In
general, the amount of NOLs we could use for any tax year after the date of the ownership change would be
limited to the value of our stock (as of the ownership change date) multiplied by the long-term tax-exempt rate.

Future sales of our common stock may depress our stock price.

We and certain of our stockholders have registered a substantial number of shares of our common stock

under a registration statement filed with the SEC. Sales of these shares of our common stock in the public
market, or the perception that these sales may occur, could cause the market price of our common stock to
decline. In addition, sales by certain of our stockholders of their shares could impair our ability to raise capital
through the sale of common or preferred stock. As of March 1, 2011, there were 44,670,930 shares of our
common stock issued and outstanding, excluding 112,891 shares of unvested restricted stock awarded under our
Amended and Restated 2005 Stock Incentive Plan, 30,420 shares issuable upon exercise of outstanding warrants
and 433,241 shares issuable upon exercise of outstanding options to purchase our common stock granted under
our Amended and Restated 2005 Stock Incentive Plan.

We could issue preferred stock which could be entitled to dividend, liquidation and other special rights and
preferences not shared by holders of our common stock or which could have anti-takeover effects.

We are authorized to issue up to 5,000,000 shares of preferred stock, par value $0.01 per share. Shares of

preferred stock may be issued from time to time in one or more series as our board of directors, by resolution or

28

resolutions, may from time to time determine each such series to be distinctively designated. The voting powers,
preferences and relative, participating, optional and other special rights, and the qualifications, limitations or
restrictions, if any, of each such series of preferred stock may differ from those of any and all other series of
preferred stock at any time outstanding, and, subject to certain limitations of our certificate of incorporation and
the Delaware General Corporation Law, or DGCL, our board of directors may fix or alter, by resolution or
resolutions, the designation, number, voting powers, preferences and relative, participating, optional and other
special rights, and qualifications, limitations and restrictions thereof, of each such series preferred stock. The
issuance of any such preferred stock could materially adversely affect the rights of holders of our common stock
and, therefore, could reduce the value of our common stock.

In addition, specific rights granted to future holders of preferred stock could be used to restrict our ability to
merge with, or sell our assets to, a third party. The ability of our board of directors to issue preferred stock could
discourage, delay or prevent a takeover of us, thereby preserving control of the company by the current
stockholders.

The existence of some provisions in our organizational documents could delay or prevent a change in

control of our company, even if that change would be beneficial to our stockholders. Our certificate of
incorporation and bylaws contain provisions that may make acquiring control of our company difficult.

Proved Oil and Natural Gas Reserves

SEC Rule-Making Activity

In December 2008, the SEC released its final rule for “Modernization of Oil and Gas Reporting.” These

rules require disclosure of oil and gas proved reserves by significant geographic area, using the arithmetic
12-month average beginning-of-the-month price for the year, as opposed to year-end prices as had previously
been required unless contractual arrangements designate the price to be used. Other significant amendments
included the following:

• Disclosure of unproved reserves: probable and possible reserves may be disclosed separately on a

voluntary basis.

•

Proved undeveloped reserve guidelines: 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 the next five years, unless the specific circumstances justify a longer time.

• Reserves estimation using new technologies: reserves may be estimated through the use of reliable

technology in addition to flow tests and production history.

• Reserves personnel and estimation process: additional disclosure is required regarding the qualifications
of the chief technical person who oversees the reserves estimation process. We are also required to
provide a general discussion of our internal controls used to assure the objectivity of the reserves
estimate.

• Non-traditional resources: the definition of oil and gas producing activities has expanded and focuses on

the marketable product rather than the method of extraction.

We adopted the rules effective December 31, 2009, as required by the SEC.

Evaluation and Review of Reserves.

Reserve estimates at December 31, 2010 were prepared by NSAI with respect to our WCBB and Niobrara
fields (22% of our proved reserves at December 31, 2010), by Pinnacle with respect to our assets in the Permian
Basin in West Texas (65% of our proved reserves at December 31, 2010) and by our personnel with respect to
our Hackberry fields and our overriding royalty and non-operated interests (13% of our proved reserves at
December 31, 2010).

NSAI and Pinnacle are independent petroleum engineering firms. Copies of their summary reserve reports
are included as Exhibit 99.1 and 99.2, respectively, to this Annual Report on Form 10-K. The technical persons
responsible for preparing our proved reserve estimates meet the requirements with regards to qualifications,
independence, objectivity and confidentiality set forth in the Standards Pertaining to the Estimating and Auditing
of Oil and Gas Reserves Information promulgated by the Society of Petroleum Engineers. Our independent third-
party engineers do not own an interest in any of our properties and are not employed by us on a contingent basis.

We maintain an internal staff of petroleum engineers and geoscience professionals who work closely with

NSAI and Pinnacle to ensure the integrity, accuracy and timeliness of the data used to calculate our proved
reserves relating to our WCBB and Niobrara fields and our assets in the Permian Basin, respectively. Our internal
technical team members meet with NSAI and Pinnacle periodically throughout the year to discuss the
assumptions and methods used in the proved reserve estimation process. We provide historical information to
NSAI and Pinnacle for our properties such as ownership interest, oil and gas production, well test data,
commodity prices and operating and development costs. Our proved reserves attributable to our Hackberry fields
and other minority interests are prepared internally by our internal staff of petroleum engineers and geoscience
professionals. Our chief reserve engineer is primarily responsible for overseeing the preparation of all of our
reserve estimates. He is a petroleum engineer with over 30 years of reservoir and operations experience and our
geophysical staff has over 60 years combined industry experience. Our technical staff uses historical information
for our properties such as ownership interest, oil and gas production, well test data, commodity prices and
operating and development costs.

The preparation of our proved reserve estimates are completed in accordance with our internal control

procedures. These procedures, which are intended to ensure reliability of reserve estimations, include the
following:

•

•

•

•

•

review and verification of historical production data, which data is based on actual production as
reported by us;

preparation of reserve estimates by our experienced reservoir engineers or under their direct supervision;

review by our reservoir engineering department of all of our reported proved reserves at the close of
each quarter, including the review of all significant reserve changes and all new proved undeveloped
reserves additions;

direct reporting responsibilities by our reservoir engineering department to our Chief Executive Officer;
and

verification of property ownership by our land department.

(1) Estimates of reserves as of year-end 2010 and 2009 were prepared using an average price equal to the

unweighted arithmetic average of hydrocarbon prices received on a field-by-field basis on the first day of
each month within the 12-month period ended December 31, 2010 and 2009, respectively, in accordance
with revised guidelines of the SEC applicable to reserves estimates as of year-end 2010 and 2009. Estimates
of reserves as of year-end 2008 were prepared using constant prices and costs in accordance with previous
guidelines of the SEC based on hydrocarbon prices received on a field-by-field basis as of December 31st of
such year. Reserve estimates do not include any value for probable or possible reserves that may exist, nor
do they include any value for undeveloped acreage. The reserve estimates represent our net revenue interest
in our properties. Although we believe these estimates are reasonable, actual future production, cash flows,
taxes, development expenditures, operating expenses and quantities of recoverable oil and natural gas
reserves may vary substantially from these estimates.

(2) Represents present value, discounted at 10% per annum, of estimated future net revenue before income tax
of our estimated proven reserves. The estimated future net revenues set forth above were determined by
using reserve quantities of proved reserves and the periods in which they are expected to be developed and
produced based on certain prevailing economic conditions. The estimated future production in our reserve
reports for the years ended December 31, 2010 and 2009 is priced based on the 12-month unweighted
arithmetic average of the first-day-of-the month price for the period January through December of the
applicable year, using $76.16 per barrel and $4.38 per MMBtu and $57.90 per barrel and 3.87 per MMBtu,
respectively, and in each case adjusted by lease for transportation fees and regional price differentials. The
estimated future production in our reserve report for the year ended December 31, 2008 is priced using
constant year-end pricing of $41.00 per barrel and $5.71 per MMBtu and adjusted by lease for
transportation fees and regional price differentials.

PV-10 is a non-GAAP measure because it excludes income tax effects. Management believes that the
presentation of the non-GAAP financial measure of PV-10 provides useful information to investors because
it is widely used by professional analysts and sophisticated investors in evaluating oil and gas companies.
PV-10 is not a measure of financial or operating performance under GAAP. PV-10 should not be considered
as an alternative to the standardized measure as defined under GAAP. We have included a reconciliation of
PV-10 to the most directly comparable GAAP measure—standardized measure of discounted future net cash
flows. The following table reconciles the standardized measure of future net cash flows to the PV-10 value:

(3) The standardized measure represents the present value of estimated future cash inflows from proved oil and

natural gas reserves, less future development, abandonment, production, and income tax expenses,
discounted at 10% per annum to reflect timing of future cash flows and using the same pricing assumptions
as were used to calculate PV-10. Standardized measure differs from PV-10 because standardized measure
includes the effect of future income taxes.

The above table does not include proved reserves net to our interest in Tatex. For further discussion of our

interest in Tatex, see Item 1. “Description of Business—Additional Properties.”

The foregoing reserves are all located within the continental United States. Reserve engineering is a
subjective process of estimating volumes of economically recoverable oil and natural gas that cannot be
measured in an exact manner. The accuracy of any reserve estimate is a function of the quality of available data
and of engineering and geological interpretation. As a result, the estimates of different engineers often vary. In
addition, the results of drilling, testing and production may justify revisions of such estimates. Accordingly,
reserve estimates often differ from the quantities of oil and natural gas that are ultimately recovered. Estimates of
economically recoverable oil and natural gas and of future net revenues are based on a number of variables and
assumptions, all of which may vary from actual results, including geologic interpretation, prices and future
production rates and costs. See “Risk Factors” contained elsewhere in this Form 10-K. We have not filed any
estimates of total, proved net oil or gas reserves with any federal authority or agency other than the SEC since the
beginning of our last fiscal year.

Additional information regarding estimates of proved reserves, proved developed reserves and proved
undeveloped reserves, or PUDs, at December 31, 2010, 2009 and 2008 and changes in proved reserves during the
last three years are contained in the Supplemental Information on Oil and Gas Exploration and Production
Activities, or Supplemental Information, in Note 21 to our consolidated financial statements included in this
report. Also contained in the Supplemental Information are our estimates of future net cash flows and discounted
future net cash flows from proved reserves. Additional information regarding our proved reserves can be found in
“Management’s Discussion and Analysis of Financial Condition and Results of Operations—Results of
Operations” and “—Critical Accounting Policies and Estimates” included in this report.

Proved Undeveloped Reserves (PUDs)

As of December 31, 2010, our proved undeveloped reserves totaled 12,474 Mboe of oil and 10,090 MMcf

of natural gas, for a total of 14,156 Mboe. Approximately 80% of our PUDs at year-end 2010 were located in the
Permian Basin, 8% of our PUDs were located in WCBB, 10% were located in our East Hackberry field and 2%
of our PUDs were located in our Niobrara field. PUDs will be converted from undeveloped to developed as the
applicable wells begin production. Changes in PUDs that occurred during 2010 were primarily due to:

• Additions of 7,952 Mboe attributable to 2010 acquisitions and extensions;

• Conversion of approximately 718 Mboe attributable to PUDs into proved developed reserves;

•

•

Positive revisions of approximately 386 Mboe in PUDs due to changes in commodity prices; and

Exclusion of 6,455 Mboe attributable to PUD locations that were not scheduled to be drilled within the
next five years.

At December 31, 2010, there were proved undeveloped reserves for four WCBB locations that have
remained undeveloped for five years or more after their disclosure as proved undeveloped reserves, a decrease
from the 11 PUD locations that had remained undeveloped for over five years at December 31, 2009. The
reserves attributed to these locations represented approximately 2.5% of our total proved reserves at
December 31, 2010 and 7.5% of our total proved reserves at December 31, 2009. We included each of these
locations because we believe them to be attractive targets. They were not drilled within five years after their
disclosure as proved undeveloped reserves due to the curtailment of our drilling activities in 2008 and 2009 as a

32

result of the sharp decrease in commodity prices. Of the four remaining PUD locations on our books at
December 31, 2010, one has already been drilled during 2011 and the other three are currently scheduled to be
drilled during the summer of 2011.

Costs incurred relating to the development of PUDs were approximately $12.2 million in 2010. Estimated

future development costs relating to the development of PUDs are projected to be approximately $71.3 million in
2011, $63.1 million in 2012, $52.0 million in 2013, $20.3 million in 2014 and $47.3 in 2015.

All PUD drilling locations are scheduled to be drilled prior to the end of 2015.

As of December 31, 2010, 19% of our total proved reserves were classified as proved developed

non-producing.

price for 2009 would have been $57.98 per barrel and $55.29 per barrel of oil equivalent. The total volume
hedged for 2009 represented approximately 49% of our total sales volumes for the year. Excluding the net
effect of the fixed price contracts, the average oil price for 2008 would have been $97.36 per barrel and

Completed and Present Drilling and Recompletion Activities

The following table sets forth information with respect to wells completed during the periods indicated. The

information should not be considered indicative of future performance, nor should it be assumed that there is
necessarily any correlation between the number of productive wells drilled, quantities of reserves found or
economic value. Productive wells are those that produce commercial quantities of hydrocarbons, whether or not
they produce a reasonable rate of return.

Title to Oil and Natural Gas Properties

It is customary in the oil and natural gas industry to make only a cursory review of title to undeveloped oil

and natural gas leases at the time they are acquired and to obtain more extensive title examinations when
acquiring producing properties. In future acquisitions, we will conduct title examinations on material portions of
such properties in a manner generally consistent with industry practice. Certain of our oil and natural gas
properties may be subject to title defects, encumbrances, easements, servitudes or other restrictions, none of
which, in management’s opinion, will in the aggregate materially restrict our operations.

ITEM 3. LEGAL PROCEEDINGS

The Louisiana Department of Revenue, or LDR, is disputing our severance tax payments to the State of

Louisiana from the sale of oil under fixed price contracts during the years 2005 through 2007. The LDR
maintains that we paid approximately $1.8 million less in severance taxes under fixed price terms than the
severance taxes we would have had to pay had we paid severance taxes on the oil at the contracted market rates
only. We have denied any liability to the LDR for underpayment of severance taxes and have maintained that we
were entitled to enter into the fixed price contracts with unrelated third parties and pay severance taxes based
upon the proceeds received under those contracts. We have maintained our right to contest any final assessment
or suit for collection if brought by the State. On April 20, 2009, the LDR filed a lawsuit in the 15th Judicial
District Court, Lafayette Parish, in Louisiana against our company seeking $2,275,729 in severance taxes, plus
interest and court costs. We filed a response denying any liability to the LDR for underpayment of severance
taxes and are defending our company in the lawsuit. The case is in the early stages of discovery.

More recently, in December 2010, the LDR filed two identical lawsuits against us in different venues to

recover allegedly underpaid severance taxes on crude oil for the period January 1, 2007 through December 31,
2010, together with a claim for attorney's fees. The petitions do not make any specific claim for damages or
unpaid taxes. As with the first lawsuit filed by the LDR in 2009, we have denied all liability and will vigorously
defend the lawsuit. The cases are in the very early stages, and we have not yet filed a response to the recent
lawsuits.

In November 2006, Cudd Pressure Control, Inc., or Cudd, filed a lawsuit against us, Great White Pressure

Control LLC, or Great White, and six former Cudd employees in the 129th Judicial District Harris County,
Texas. The lawsuit was subsequently removed to the United States District Court for the Southern District of
Texas (Houston Division). The lawsuit alleged RICO violations and several other causes of action relating to
Great White’s employment of the former Cudd employees and sought unspecified monetary damages and
injunctive relief. On stipulation by the parties, the plaintiff’s RICO claim was dismissed without prejudice by
order of the court on February 14, 2007. We filed a motion for summary judgment on October 5, 2007. The
Court entered a final interlocutory judgment in favor of all defendants, including us, on April 8, 2008. On
November 3, 2008, Cudd filed its appeal with the U.S. Court of Appeals for the Fifth Circuit. The Fifth Circuit
vacated the district court decision finding, among other things, that the district court should not have entered
summary judgment without first allowing more discovery. The case was remanded to the district court, and Cudd
filed a motion to remand the case to the original state court, which motion was granted. On February 3, 2010,
Cudd filed its second amended petition with the state court (a) alleging that we conspired with the other
defendants to misappropriate, and misappropriated Cudd’s trade secrets and caused its employees to breach their
fiduciary duties, and (b) seeking unspecified monetary damages. On April 13, 2010, our motion to be dismissed
from the proceeding for lack of personal jurisdiction was denied. This state court proceeding is in its initial
stages. In 2011, the parties have continued with written discovery and production of documents. On February 15,
2011, Cudd filed a third amended petition seeking $26.5 million (based on a report prepared by its expert) plus
disgorgement of $6.0 million in payments by Great White to the individual defendants and punitive damages.
Gulfport denies these claims with respect to itself.

On July 30, 2010, six individuals and one limited liability company sued 15 oil and gas companies in
Cameron Parish Louisiana for contamination across the surface of where the defendants operated in an action
entitled Reeds et al. v. BP American Production Company et al., 38th Judicial District. No. 10-18714. The
plaintiffs’ original petition for damages, which did not name us as a defendant, alleges that the plaintiffs’
property located in Cameron Parish, Louisiana within the Hackberry oil field is contaminated as a result of
historic oil and gas exploration and production activities. Plaintiffs allege that the defendants, which in addition
to BP America Production Company include ExxonMobil Corporation, Shell Oil Company, ConocoPhillips
Company, Sun Oil Company and Schlumberger Technology Corporation, conducted, directed and participated in
various oil and gas exploration and production activities on their property which allegedly have contaminated or
otherwise caused damage to the property, and have sued the defendants for alleged breaches of oil, gas and

36

mineral leases, as well as for alleged negligence, trespass, failure to warn, strict liability, punitive damages, lease
liability, contract liability, unjust enrichment, restoration damages, assessment and response costs and stigma
damages. On December 7, 2010, we were served with a copy of the plaintiffs’ first supplemental and amending
petition which added four additional plaintiffs and six additional defendants, including us, bringing the total
number of defendants to 21. It also increased the total acreage at issue in this litigation from 240 acres to
approximately 1,700 acres. In addition to the damages sought in the original petition, the plaintiffs now also seek:
damages sufficient to cover the cost of conducting a comprehensive environmental assessment of all present and
yet unidentified pollution and contamination of their property; the cost to restore the property to its pre-polluted
original condition; damages for mental anguish and annoyance, discomfort and inconvenience caused by the
nuisance created by defendants; land loss and subsidence damages and the cost of backfilling canals and other
excavations; damages for loss of use of land and lost profits and income; attorney fees and expenses; and
damages for evaluation and remediation of any contamination that threatens groundwater. On January 21, 2011,
we filed a pleading challenging the legal sufficiency of the petitions and requesting that they either be dismissed
or that plaintiffs be required to amend such petitions. Our motion is currently set to be heard on March 23, 2011.

Due to the current stages of the above litigation, the outcomes are uncertain and management cannot
determine the amount of loss, if any, that may result. Litigation is inherently uncertain. Adverse decisions in one
or more of the above matters could have a material adverse affect on our financial condition or results of
operations.

In addition to the above, we have been named as a defendant in various other lawsuits related to our
business. The ultimate resolution of such other matters is not expected to have a material adverse effect on our
financial condition or results of operations.

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 the consolidated financial
statements and related notes included elsewhere in this Annual Report on Form 10-K. This discussion contains
forward-looking statements reflecting our current expectations, estimates and assumptions concerning events
and financial trends that may affect our future operating results or financial position. Actual results and the
timing of events may differ materially from those contained in these forward-looking statements due to a number
of factors, including those discussed in the sections entitled “Risk Factors” and “Cautionary Note Regarding
Forward-Looking Statements” appearing elsewhere in this Annual Report on Form 10-K.

Overview

We are an independent oil and natural gas exploration and production company with our principal producing

properties located along the Louisiana Gulf Coast in the West Cote Blanche Bay, or WCBB, and Hackberry
fields, and in West Texas in the Permian Basin. In 2010, we acquired an acreage position in Western Colorado in
the Niobrara Formation. We also hold a significant acreage position in the Alberta oil sands in Canada through
our interest in Grizzly Oil Sands ULC, and have interests in entities that operate in Southeast Asia, including the
Phu Horm gas field in Thailand. We seek to achieve reserve growth and increase our cash flow through our
annual drilling programs.

2010 Highlights

• Oil and natural gas revenues increased 49% to $127.6 million for the year ended December 31, 2010

from $85.6 million for the year ended December 31, 2009.

• Net income increased 100% to $47.4 million for the year ended December 31, 2010 from $23.6 million

for the year ended December 31, 2009.

•

Production increased 18% to approximately 1,976,000 barrels of oil equivalent, or BOE, for the year
ended December 31, 2010 from approximately 1,677,000 BOE for the year ended December 31, 2009.

• During 2010, we drilled 57 gross (42 net) wells, which includes 26 gross (11 net) wells drilled by our
operators in the Permian Basin and Bakken, and recompleted 87 gross (84 net) wells. Of our 57 new
wells drilled, 56 were completed as producing wells and one was waiting on completion.

• During 2010, we acquired approximately 6,500 additional net acres in the Permian Basin, which brought

our total net acreage position in the Permian Basin to approximately 14,700 net acres.

•

•

Effective as of April 1, 2010, we acquired leasehold interests in the Niobrara Formation in Colorado and
held leases for 19,172 net acres as of March 1, 2011.

In May 2010, we completed an underwritten public offering of 1,668,503 shares of our common stock
and received approximately $21.4 million in net proceeds, which we used to fund the acquisition of our
interests in the Niobrara Formation, pay the purchase price for a portion of the additional acreage
acquired by us in the Permian Basin in 2010 and for general corporate purposes.

• On September 30, 2010, we entered into a new $100.0 million senior secured revolving credit facility
with The Bank of Nova Scotia, as administrative agent, letter of credit issuer and lead arranger, and
Amegy Bank National Association, and repaid and terminated our existing revolving credit facility and
term loan, each with Bank of America, N.A., as administrative agent, with borrowings under our new
revolving credit facility. Our borrowing base under this facility was increased from $50.0 million to
$65.0 million in December 2010.

Recent Developments

In February 2011, we entered into an agreement to acquire certain leasehold interests located in the Utica

Shale in Ohio. The agreement also grants us an exclusive right of first refusal for a period of six months on

41

certain additional tracts leased by the seller. Windsor, an affiliate of ours, has agreed to participate with us on a
50/50 basis in the acquisition of all of the leases described above. We will be the operator on this acreage in the
Utica Shale. The purchase price for our 50% interest in the initial acreage is approximately $31.6 million, subject
to certain closing adjustments. This transaction is expected to close in mid-May 2011.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations are based upon consolidated

financial statements, which have been prepared in accordance with accounting principles generally accepted in
the United States of America, or GAAP. The preparation of these consolidated financial statements requires us to
make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses. We
have identified certain of these policies as being of particular importance to the portrayal of our financial position
and results of operations and which require the application of significant judgment by our management. We
analyze our estimates including those related to oil and natural gas properties, revenue recognition, income taxes
and commitments and contingencies, and base our estimates on historical experience and various other
assumptions that we believe to be reasonable under the circumstances. Actual results may differ from these
estimates under different assumptions or conditions. We believe the following critical accounting policies affect
our more significant judgments and estimates used in the preparation of our consolidated financial statements:

Oil and Natural Gas Properties. We use the full cost method of accounting for oil and natural gas
operations. Accordingly, all costs, including non-productive costs and certain general and administrative costs
directly associated with acquisition, exploration and development of oil and natural gas properties, are
capitalized. Companies that use the full cost method of accounting for oil and gas properties are required to
perform a ceiling test each quarter. The test determines a limit, or ceiling, on the book value of the oil and gas
properties. Net capitalized costs are limited to the lower of unamortized cost net of deferred income taxes or the
cost center ceiling. The cost center ceiling is defined as the sum of (a) estimated future net revenues, discounted
at 10% per annum, from proved reserves, based on the 12-month unweighted average of the
first-day-of-the-month price for the period 2010 and 2009, and prior to 2009, unescalated year-end prices and
costs, adjusted for any contract provisions or financial derivatives, if any, that hedge our oil and natural gas
revenue, and excluding the estimated abandonment costs for properties with asset retirement obligations recorded
on the balance sheet, (b) the cost of properties not being amortized, if any, and (c) the lower of cost or market
value of unproved properties included in the cost being amortized, including related deferred taxes for
differences between the book and tax basis of the oil and natural gas properties. If the net book value, including
related deferred taxes, exceeds the ceiling, an impairment or noncash writedown is required. Such capitalized
costs, including the estimated future development costs and site remediation costs of proved undeveloped
properties are depleted by an equivalent units-of-production method, converting gas to barrels at the ratio of six
Mcf of gas to one barrel of oil. No gain or loss is recognized upon the disposal of oil and natural gas properties,
unless such dispositions significantly alter the relationship between capitalized costs and proven oil and natural
gas reserves. Oil and natural gas properties not subject to amortization consist of the cost of undeveloped
leaseholds and totaled $16.8 million at December 31, 2010 and $17.5 million at December 31, 2009. These costs
are reviewed quarterly by management for impairment, with the impairment provision included in the cost of oil
and natural gas properties subject to amortization. Factors considered by management in its impairment
assessment include our drilling results and those of other operators, the terms of oil and natural gas leases not
held by production and available funds for exploration and development.

Ceiling Test. Companies that use the full cost method of accounting for oil and gas properties are required to

perform a ceiling test each quarter. The test determines a limit, or ceiling, on the book value of the oil and gas
properties. Net capitalized costs are limited to the lower of unamortized cost net of deferred income taxes or the
cost center ceiling. The cost center ceiling is defined as the sum of (a) estimated future net revenues, discounted
at 10% per annum, from proved reserves, based on the 12-month unweighted average of the
first-day-of-the-month price for the period January – December of the applicable year beginning with 2009, and
prior to 2009, unescalated year-end prices and costs, adjusted for any contract provisions or financial derivatives,

42

if any, that hedge our oil and natural gas revenue, and excluding the estimated abandonment costs for properties
with asset retirement obligations recorded on the balance sheet, (b) the cost of properties not being amortized, if
any, and (c) the lower of cost or market value of unproved properties included in the cost being amortized,
including related deferred taxes for differences between the book and tax basis of the oil and natural gas
properties. If the net book value, including related deferred taxes, exceeds the ceiling, an impairment or noncash
writedown is required. Ceiling test impairment can give us a significant loss for a particular period; however,
future depletion expense would be reduced. A decline in oil and gas prices may result in an impairment of oil and
gas properties. For instance, as a result of the drop in commodity prices on December 31, 2008 and subsequent
reduction in our proved reserves, we recognized a ceiling test impairment of $272.7 million for the year ended
December 31, 2008. If prices of oil, natural gas and natural gas liquids decline, we may be required to further
write down the value of our oil and gas properties, which could negatively affect our results of operations. No
ceiling test impairment was required for the year ended December 31, 2010.

Asset Retirement Obligations. We have obligations to remove equipment and 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 associated production facilities.

We account for abandonment and restoration liabilities under FASB ASC 410 which requires us to record a
liability equal to the fair value of the estimated cost to retire an asset. The asset retirement liability is recorded in
the period in which the obligation meets the definition of a liability, which is generally when the asset is placed
into service. When the liability is initially recorded, we increase the carrying amount of the related long-lived
asset by an amount equal to the original liability. The liability is accreted to its present value each period, and the
capitalized cost is depreciated over the useful life of the related long-lived asset. Upon settlement of the liability
or the sale of the well, the liability is reversed. These liability amounts may change because of changes in asset
lives, estimated costs of abandonment or legal or statutory remediation requirements.

The fair value of the liability associated with these retirement obligations is determined using significant
assumptions, including current estimates of the plugging and abandonment or retirement, annual inflations of
these costs, the productive life of the asset and our risk adjusted cost to settle such obligations discounted using
our credit adjustment risk free interest rate. Changes in any of these assumptions can result in significant
revisions to the estimated asset retirement obligation. Revisions to the asset retirement obligation are recorded
with an offsetting change to the carrying amount of the related long-lived asset, resulting in prospective changes
to depreciation, depletion and amortization expense and accretion of discount. Because of the subjectivity of
assumptions and the relatively long life of most of our oil and natural gas assets, the costs to ultimately retire
these assets may vary significantly from previous estimates.

Oil and Gas Reserve Quantities. Our estimate of proved reserves is based on the quantities of oil and natural

gas that engineering and geological analysis demonstrate, with reasonable certainty, to be recoverable from
established reservoirs in the future under current operating and economic parameters. Netherland, Sewell &
Associates, Inc., Pinnacle Energy Services, LLC and to a lesser extent our personnel have prepared reserve
reports of our reserve estimates at December 31, 2010 on a well-by-well basis for our properties.

Reserves and their relation to estimated future net cash flows impact our depletion and impairment

calculations. As a result, adjustments to depletion and impairment are made concurrently with changes to reserve
estimates. Our reserve estimates and the projected cash flows derived from these reserve estimates have been
prepared in accordance with SEC guidelines. The accuracy of our reserve estimates is a function of many factors
including the following:

•

•

•

•

the quality and quantity of available data;

the interpretation of that data;

the accuracy of various mandated economic assumptions; and

the judgments of the individuals preparing the estimates.

43

Our proved reserve estimates are a function of many assumptions, all of which could deviate significantly

from actual results. As such, reserve estimates may materially vary from the ultimate quantities of oil and natural
gas eventually recovered.

Income Taxes. We use the asset and liability method of accounting for income taxes, under which deferred
tax assets and liabilities are recognized for the future tax consequences of (1) temporary differences between the
financial statement carrying amounts and the tax bases of existing assets and liabilities and (2) operating loss and
tax credit carryforwards. Deferred income tax assets and liabilities are based on enacted tax rates applicable to
the future period when those temporary differences are expected to be recovered or settled. The effect of a
change in tax rates on deferred tax assets and liabilities is recognized in income during the period the rate change
is enacted. Deferred tax assets are recognized in the year in which realization becomes determinable.
Periodically, management performs a forecast of its taxable income to determine whether it is more likely than
not that a valuation allowance is needed, looking at both positive and negative factors. A valuation allowance for
our deferred tax assets is established, if in management’s opinion, it is more likely than not that some portion will
not be realized. At December 31, 2010, a valuation allowance of $54.4 million had been provided for deferred
tax assets based on the uncertainty of future taxable income.

Revenue Recognition. We derive almost all of our revenue from the sale of crude oil and natural gas
produced from our oil and gas properties. Revenue is recorded in the month the product is delivered to the
purchaser. We receive payment on substantially all of these sales from one to three months after delivery. At the
end of each month, we estimate the amount of production delivered to purchasers that month and the price we
will receive. Variances between our estimated revenue and actual payment received for all prior months are
recorded at the end of the quarter after payment is received. Historically, our actual payments have not
significantly deviated from our accruals.

Commitments and Contingencies. Liabilities for loss contingencies arising from claims, assessments,
litigation or other sources are recorded when it is probable that a liability has been incurred and the amount can
be reasonably estimated. We are involved in certain litigation for which the outcome is uncertain. Changes in the
certainty and the ability to reasonably estimate a loss amount, if any, may result in the recognition and
subsequent payment of legal liabilities.

Derivative Instruments and Hedging Activities. We seek to reduce our exposure to unfavorable changes in

oil prices by utilizing energy swaps and collars, or fixed-price contracts. We follow the provisions of FASB ASC
815, “Derivatives and Hedging,” as amended. It requires that all derivative instruments be recognized as assets or
liabilities in the balance sheet, measured at fair value. We estimate the fair value of all derivative instruments
using established index prices and other sources. These values are based upon, among other things, futures
prices, correlation between index prices and our realized prices, time to maturity and credit risk. The values
reported in the financial statements change as these estimates are revised to reflect actual results, changes in
market conditions or other factors.

The accounting for changes in the fair value of a derivative depends on the intended use of the derivative
and the resulting designation. Designation is established at the inception of a derivative, but re-designation is
permitted. For derivatives designated as cash flow hedges and meeting the effectiveness guidelines of FASB
ASC 815, changes in fair value are recognized in accumulated other comprehensive income until the hedged item
is recognized in earnings. Hedge effectiveness is measured at least quarterly based on the relative changes in fair
value between the derivative contract and the hedged item over time. We recognize any change in fair value
resulting from ineffectiveness immediately in earnings.

To mitigate the effects of commodity price fluctuations, for the period January 2010 through February 2010,
we were party to forward sales contracts for the sale of 3,000 barrels of WCBB production per day at a weighted
average daily price of $54.81 per barrel, before transportation costs and differentials. For the period March 2010
through December 2010, we were party to forward sales contracts for the sale of 2,300 barrels of WCBB

44

production per day at a weighted average daily price of $58.24 per barrel, before transportation costs and
differentials. In November 2010, we entered into fixed price swaps for 2,000 barrels of oil per day at a weighted
average price of $86.96 per barrel, before transportation costs and differentials, for the period January 2011
through December 2011. Under the 2010 contracts, we delivered approximately 45% of our estimated 2010
production. Under the 2011 contracts, we have committed to deliver approximately 30% to 33% of our estimated
2011 production. Such arrangements may expose us to risk of financial loss in certain circumstances, including
instances where production is less than expected or oil prices increase. These forward sales contracts and fixed
price swaps are accounted for as cash flow hedges and recorded at fair value pursuant to FASB ASC 815 and
related pronouncements.

RESULTS OF OPERATIONS

Results of Operations

The markets for oil and natural gas have historically been, and will continue to be, volatile. Prices for oil

and natural gas may fluctuate in response to relatively minor changes in supply and demand, market uncertainty
and a variety of factors beyond our control.

approximately 45% of our total sales volumes for the year. Excluding the effect of the fixed price contracts,
the average oil price for 2009 would have been $57.98 per barrel and $55.29 per barrel of oil equivalent.
The total volume hedged for 2009 represented approximately 49% of our total sales volumes for the year.
Excluding the net effect of the fixed price contracts, the average oil price for 2008 would have been $97.36

(2) Does not include production taxes.

From 2009 to 2010, our net equivalent oil production increased 18% from 1,677,000 barrels to 1,976,000
barrels due to increased drilling activity, the success of our drilling activities and our acquisitions of additional
properties in the Permian Basin and the Niobrara Formation. From 2008 to 2009, our net equivalent oil
production decreased 5% from 1,764,000 barrels to 1,677,000 barrels due to our reduced drilling activity and
normal production declines. We currently estimate that our 2011 production will be between 2,200,000 and
2,400,000 BOE. However, such estimate may change based on a change in our expected drilling and
recompletion activities or the changing economic climate and unforeseen events, such as hurricanes.

Comparison of the Years Ended December 31, 2010 and December 31, 2009

We reported net income of $47,363,000 for the year ended December 31, 2010, as compared to net income
of $23,627,000 for the year ended December 31, 2009. This 100% increase in 2010 was due primarily to a 27%
increase in realized BOE prices to $64.61 from $51.01 and an 18% increase in net production to 1,976,000 BOE,
partially offset by an 8% increase in lease operating expenses, a 21% increase in general and administrative
expenses and a 43% increase in production taxes.

Oil and Gas Revenues. For the year ended December 31, 2010, we reported oil and natural gas revenues of

$127,636,000 as compared to oil and natural gas revenues of $85,576,000 during 2009. This $42,060,000, or
49%, increase in revenues is primarily attributable to a 27% increase in realized BOE prices to $64.61 from
$51.01 and an 18% increase in net production to 1,975,576 BOE for the year ended December 31, 2010 from
1,677,474 BOE for the year ended December 31, 2009.

Lease Operating Expenses. Lease operating expenses not including production taxes increased to

$17,614,000 for 2010 from $16,316,000 for 2009. This increase is mainly a result of an increase in ad valorem
taxes and expenses related to well workovers.

Production Taxes. Production taxes increased to $13,966,000 for 2010 from $9,797,000 for 2009. This
increase was primarily related to a 49% increase in oil and gas revenues as a result of a 27% increase in average
realized BOE price received and an 18% increase in production.

Depreciation, Depletion and Amortization. Depreciation, depletion and amortization, or DD&A, expense
increased to $38,907,000 for 2010, and consisted of $38,600,000 in depletion on oil and natural gas properties
and $307,000 in depreciation of other property and equipment. This compares to total depreciation, depletion and
amortization expense of $29,225,000 for 2009. This increase was due to an increase in our full cost pool as a
result of our capital activities and an increase in our production used to calculate our total DD&A expense.

46

General and Administrative Expenses. Net general and administrative expenses increased to $6,063,000 for
2010 from $4,992,000 for 2009. This $1,071,000 increase was primarily due to a $450,000 increase in franchise
taxes, a $200,000 increase in legal expenses and increases related to salaries, benefits expenses partially offset by
an increase in general and administrative overhead related to exploration and development activity capitalized to
the full cost pool.

Accretion Expense. Accretion expense increased slightly to $617,000 for 2010 from $582,000 for 2009.

Interest Expense. Interest expense increased to $2,761,000 for 2010 from $2,309,000 for 2009. This increase

was due to an increase in the interest rate paid as well as the recognition of approximately $225,000 in
unamortized loan fees associated with the termination of the Bank of America revolving credit facility. Effective
September 30, 2010, this facility, along with the term loan with Bank of America, were repaid with borrowings
under our new senior secured revolving credit agreement with The Bank of Nova Scotia, as administrative agent
and letter of credit issuer and lead arranger, and Amegy Bank National Association, entered into on
September 30, 2010. This increase in interest expense was partially offset by a decrease in average debt
outstanding for the year ended December 31, 2010, as compared to the year ended December 31, 2009. Total
debt outstanding under our new revolving credit facility was $49.5 million as of December 31, 2010, as
compared to $49.9 million outstanding under our prior facilities with Bank of America as of the same date in
2009. Total weighted debt outstanding under our facilities was $46.9 million for 2010 and $59.9 million for
2009. Until September 30, 2010, amounts borrowed under our term loan and revolving credit facility with Bank
of America bore interest of 3.76% and 3.25%, respectively. At December 31, 2010, amounts borrowed under our
new revolving credit agreement bore interest at the Eurodollar rate of 3.77%.

Income Taxes. As of December 31, 2010, we had a net operating loss carry forward of approximately $52.4

million, in addition to numerous temporary differences, which gave rise to a deferred tax asset. Periodically,
management performs a forecast of our taxable income to determine whether it is more likely than not that a
valuation allowance is needed, looking at both positive and negative factors. A valuation allowance for our
deferred tax assets is established if, in management’s opinion, it is more likely than not that some portion will not
be realized. At December 31, 2010, a valuation allowance of $54.4 million had been provided for deferred tax
assets, with the exception of $628,000 for alternative minimum taxes. We paid $40,000 of state income tax for
the year ended December 31, 2010.

Comparison of the Years Ended December 31, 2009 and December 31, 2008

We reported net income of $23,627,000 for the year ended December 31, 2009, as compared to a net loss of
$184,502,000 for the year ended December 31, 2008. This net income is primarily attributable to a 29% decrease
in lease operating expenses, a 27% decrease in general and administrative expenses and a 38% decrease in
production taxes, partially offset by a 36% decrease in realized BOE prices to $51.01 from $80.30 and a 5%
decrease in net production to 1,677,474 BOE. In addition, the net loss for 2008 was primarily attributable to an
impairment charge of $272,722,000 related to the drastic decline in oil and gas prices. Further, we had
$1,050,000 of insurance proceeds received during the year ended December 31, 2009 compared to insurance
proceeds of $769,000 received during 2008.

Oil and Gas Revenues. For the year ended December 31, 2009, we reported oil and natural gas revenues of

$85,576,000 as compared to oil and natural gas revenues of $141,650,000 during 2008. This $56,074,000, or
40%, decrease in revenues is primarily attributable to a 36% decrease in realized BOE prices to $51.01 from
$80.30 and a 5% decrease in net production to 1,677,474 BOE for the year ended December 31, 2009 from
1,764,053 BOE for the year ended December 31, 2008.

Lease Operating Expenses. Lease operating expenses not including production taxes decreased to

$16,316,000 for 2009 from $22,856,000 for 2008. This decrease is mainly a result of a decrease in contract labor
expenses, a decrease in workovers, compressor and other equipment rentals and repairs, a decrease in the cost of
chemicals and supplies and a decrease in personal property taxes. In addition, the lease operating expenses for
2008 included $3,408,000 of unreimbursed expenses related to hurricane repairs as compared to approximately
$23,000 of unreimbursed expenses related to hurricane repairs in 2009.

Production Taxes. Production taxes decreased to $9,797,000 for 2009 from $15,813,000 for 2008. This
decrease was primarily related to a 40% decrease in oil and gas revenues mainly as a result of the decrease in the
average realized BOE price received.

Depreciation, Depletion and Amortization. Depreciation, depletion and amortization expense decreased to
$29,225,000 for 2009, and consisted of $28,939,000 in depletion on oil and natural gas properties and $286,000
in depreciation of other property and equipment. This compares to total depreciation, depletion and amortization
expense of $42,472,000 for 2008. This decrease was due primarily to the reduction in the book value of our oil
and gas properties used to calculate depreciation, depletion and amortization expense. This reduction resulted
from the drop in commodity prices reflected as of December 31, 2008 and the resulting reduction in our proved
reserves which caused us to recognize a ceiling test impairment to our full cost pool of $272,722,000 for the year
ended December 31, 2008.

Impairment of Oil and Gas Properties. We use the full cost method of accounting for oil and gas properties
and are required to perform a ceiling test each quarter. The test determines a limit, or ceiling, on the book value
of our oil and gas properties. Net capitalized costs are limited to the lower of unamortized cost net of deferred
income taxes or the cost center ceiling. The cost center ceiling is defined as the sum of (a) estimated future net
revenues, discounted at 10% per annum, from proved reserves, based on the 12-month unweighted average of the
first-day-of-the-month price for the period of January through December 2009, and prior to 2009, unescalated
year-end prices and costs, adjusted for any contract provisions or financial derivatives, if any, that hedge our oil
and natural gas revenue, and excluding the estimated abandonment costs for properties with asset retirement
obligations recorded on our balance sheet, (b) the cost of properties not being amortized, if any, and (c) the lower
of cost or market value of unproved properties included in the cost being amortized, less income tax effects
related to differences between the book and tax basis of the oil and natural gas properties. If the net book value
reduced by the related net deferred income tax liability exceeds the ceiling, an impairment or noncash write-
down is required. There was no impairment charge for the year ended December 31, 2009. As a result of the drop
in commodity prices on December 31, 2008, we recognized a ceiling test impairment of $272,722,000 for the
year ended December 31, 2008.

General and Administrative Expenses. Net general and administrative expenses decreased to $4,992,000 for
2009 from $6,843,000 for 2008. This $1,851,000 decrease was due primarily to reductions in franchise taxes as a

48

result of the impairment mentioned in the depreciation, depletion and amortization section above which reduced
our net assets used to calculate franchise taxes, a reduction in stock based compensation expenses, reductions in
payroll costs including payroll taxes and related benefits mainly due to decreases in the total number of
employees partially offset by a decrease in general and administrative reimbursements from our affiliates and a
decrease in general and administrative overhead related to exploration and development activity capitalized to the
full cost pool.

Accretion Expense. Accretion expense increased slightly to $582,000 for 2009 from $560,000 for 2008.

Interest Expense. Interest expense decreased to $2,309,000 for 2009 from $4,762,000 for 2008 due to a
decrease in average debt outstanding and lower interest rates on amounts borrowed under our facilities with Bank
of America. Total debt outstanding under our facilities with Bank of America was $49.9 million as of
December 31, 2009 and $68.1 million as of the same date in 2008. Total weighted debt outstanding under our
facilities with Bank of America was $59.9 million for 2009 and $84.2 million for 2008. As of December 31,
2009, amounts borrowed under our revolving credit facility and our two term loans with Bank of America bore
interest of 3.73%, 4.23% and 3.25%, respectively.

Income Taxes. As of December 31, 2009, we had a net operating loss carry forward of approximately $55.7

million, in addition to numerous temporary differences, which gave rise to a deferred tax asset. Periodically,
management performs a forecast of our taxable income to determine whether it is more likely than not that a
valuation allowance is needed, looking at both positive and negative factors. A valuation allowance for our
deferred tax assets is established if, in management’s opinion, it is more likely than not that some portion will not
be realized. At December 31, 2009, a valuation allowance of $73.2 million had been provided for deferred tax
assets, as the Company has historically had non-taxable income and has future projections of no taxable income
during the carryforward period, with the exception of $533,000 related to alternative minimum taxes. We had
$28,000 of state income tax expense for the year ended December 31, 2009.

Liquidity and Capital Resources

Overview. Historically, our primary sources of funds have been cash flow from our producing oil and
natural gas properties, borrowings under our bank and other credit facilities and the issuance of equity securities.
Our ability to access any of these sources of funds can be significantly impacted by decreases in oil and natural
gas prices or our oil and gas production. During 2009, we also received proceeds from the sale of certain of our
Bakken assets and, in 2010, we received net proceeds (before offering expenses) of approximately $21.6 million
from the sale of our common stock in an underwritten public offering.

Net cash flow provided by operating activities was $85,835,000 for 2010, as compared to $53,299,000 for

2009. This increase was primarily the result of an increase in cash receipts from our oil and natural gas
purchasers due to a 27% increase in net realized prices and an 18% increase in our net BOE production.

Net cash flow provided by operating activities was $53,299,000 for 2009, as compared to $135,323,000 for

2008. This decrease was primarily the result of a decrease in cash receipts from our oil and natural gas purchasers
due to a 36% decrease in net realized prices and a 5% decrease in our net BOE production.

Net cash used in investing activities for 2010 was $105,315,000, as compared to $39,246,000 for 2009.
During 2010, we spent $101,644,000 in additions to oil and natural gas properties, of which $51,356,000 was
spent on our 2010 drilling and recompletion programs, $16,735,000 was spent on acquisitions in our Niobrara
and Permian fields, $11,697,000 was spent on expenses attributable to the wells drilled during 2009, $3,093,000
was spent on our 2009 recompletions, $6,838,000 was spent on compressors and other facility enhancements,
$1,425,000 was spent on plugging costs, $771,000 was spent on lease related costs and $3,449,000 was spent on
tubulars, with the remainder attributable mainly to capitalized general and administrative expenses. In addition,
we paid $3,719,000 in cash calls to Grizzly during 2010. During 2010, we used cash from operations, borrowings
under our credit facilities and proceeds from our equity offering to fund our investing activities.

49

Net cash used in investing activities for 2009 was $39,246,000, as compared to $136,823,000 for 2008.

During the year ended December 31, 2009, we spent (a) $49,533,000 in additions to oil and natural gas
properties, of which $20,296,000 was spent on our 2009 drilling and recompletion programs, $14,255,000 was
spent on costs attributable to the wells drilled during 2008, $3,719,000 was spent on our 2008 recompletions,
$1,191,000 was spent on barges and other facility enhancements, $866,000 was spent on plugging and
abandonment activities, $2,853,000 was spent on lease related costs and $1,744,000 was spent on tubulars, with
the remainder attributable mainly to capitalized general and administrative expenses, and (b) $3,813,000 on our
investment in Tatex III and we loaned $4,377,000 to Grizzly. In May, September and December 2009, we
received aggregate net proceeds of approximately $18,286,000 from our sale of properties in the Bakken. During
the year ended December 31, 2009, we used cash from operations and proceeds from the sale of Bakken
properties to fund our investing activities.

Net cash provided by financing activities for 2010 was $20,224,000 as compared to net cash used by

financing activities of $18,273,000 for 2009. The 2010 amount provided by financing activities is primarily
attributable to the net proceeds of $21,358,000 from our equity offering and borrowings of $52,200,000 under
our new credit facility, partially offset by principal payments of $49,903,000 on borrowings under our prior
credit facilities with Bank of America. We used the net proceeds of our 2010 equity offering to fund the
acquisition of our interests in the Niobrara Formation, pay the purchase price for a portion of the additional
acreage acquired by us in the Permian Basin in 2010 and for general corporate purposes.

The 2009 amount used by financing activities is primarily attributable to principal payments on borrowings

of $18,206,000 under our credit facility with Bank of America, partially offset by $30,000 received from the
exercise of stock options.

Net cash provided by financing activities for 2008 was $4,680,000. The 2008 amount was primarily

attributable to $30,000,000 of borrowings under our line of credit, mostly offset by repayments on the line.

Credit Facility. In March 2005, we entered into a three-year secured credit agreement with Bank of
America, N.A. providing for a revolving credit facility. The credit agreement was subsequently amended and
restated from time to time and, among other things, the maturity date was extended to April 1, 2011. Borrowings
under the revolving credit facility were subject to a borrowing base limitation, which was initially set at $18.0
million, subject to adjustment. Effective July 19, 2007, the credit facility was increased to $150.0 million and
effective December 20, 2007, the amount available under the borrowing base limitation was increased to $90.0
million.

On August 31, 2009, the lender completed its periodic redetermination of our borrowing base giving
consideration to our year-end 2008 and mid-year 2009 reserve information and the lender’s then current pricing
decks, among other factors. As a result of this redetermination, our available borrowing base was reset at $45.0
million, primarily in response to significant declines in commodity prices. Our outstanding principal balance at
the effective time of this redetermination was approximately $59.0 million. The approximately $14.0 million of
outstanding borrowings under the credit facility in excess of the new borrowing base was converted into a term
loan as of August 31, 2009. An initial $2.0 million payment was made on the term loan at that time and we
agreed to make additional monthly payments of $1.0 million commencing on September 30, 2009, with all
unpaid amounts due on March 31, 2010. We paid the outstanding balance of the term loan in full in February
2010. On September 30, 2010, we repaid all borrowings under the credit facility.

Outstanding borrowings under the term loan accrued interest at the Eurodollar rate (as defined in the credit

agreement) plus 4.0% or, at our option, at the base rate (which was the highest of the lender’s prime rate, the
Federal funds rate plus half of 1%, and the one-month Eurodollar rate plus 1%) plus 3%. Effective August 31,
2009, we also agreed to an adjustment in the commitment fees, interest rates for revolving loans and fees for
letters of credit under the credit facility. Specifically, we agreed to pay (a) commitment fees ranging from 0.5%
to 0.625% (an increase from 0.15% to 0.25%), (b) margin interest rates ranging from 2.75% to 3.50% for

50

Eurodollar loans (an increase from 1.25% to 2.0%), (c) margin interest rates ranging from 1.75% to 2.5% for
base rate loans (an increase from 1.25% to 2.0%), and (d) letter of credit fees at the margin interest rates for
Eurodollar loans, in each case based on our utilization percentage. In addition, we agreed to limitations on certain
dispositions and investments and to mandatory prepayments of the loans from the net cash proceeds of specified
asset sales and other events.

Our obligations under the credit facility were collateralized by a lien on substantially all of our Louisiana

and West Texas assets and were guaranteed by our subsidiaries. The restated credit agreement contained certain
affirmative and negative covenants, including, but not limited to the following financial covenants: (a) the ratio
of funded debt to EBITDAX (net income before deductions for taxes, excluding unrealized gains and losses
related to trading securities and commodity hedges, plus depreciation, depletion, amortization and interest
expense, plus exploration costs deducted in determining net income under full cost accounting) for a twelve-
month period could not be greater than 2.00 to 1.00; and (b) the ratio of EBITDAX to interest expense for a
twelve-month period could not be less than 3.00 to 1.00.

On July 10, 2006, we entered into a $5.0 million term loan agreement with Bank of America, N.A. related to
the purchase of new gas compressor units. The loan began amortizing quarterly on March 31, 2007 on a straight-
line basis over seven years based on the outstanding principal balance at December 31, 2006. We made quarterly
principal payments of approximately $176,000. Amounts borrowed bore interest at Bank of America Prime. We
made quarterly interest payments on amounts borrowed under the agreement. Our obligations under the
agreement were collateralized by a lien on the compressor units. On September 30, 2010, we repaid this loan in
full with borrowings under the new revolving credit agreement discussed below.

On September 30, 2010, we entered into a new $100.0 million senior secured revolving credit facility with
The Bank of Nova Scotia, or Scotia Capital, as administrative agent, letter of credit issuer and lead arranger, and
Amegy Bank National Association, which facility matures on September 30, 2013. The new revolving credit
agreement provided for an initial borrowing base availability of $50.0 million, which was increased to $65.0
million effective December 24, 2010.

As of December 31, 2010, we had an outstanding balance of $49.5 million drawn under our new revolving

credit agreement, which is included in long-term debt, net of current maturities, on our accompanying
consolidated balance sheet at December 31, 2010. The amounts borrowed under our new revolving credit
agreement were used to repay our outstanding indebtedness under our prior revolving credit facility ($42.0
million) and term loan ($2.5 million), each with Bank of America, N.A., as administrative agent, and for general
corporate purposes. The new revolving credit agreement is secured by substantially all of our assets. Our wholly-
owned subsidiaries guaranteed our obligations under the new revolving credit agreement.

Advances under the new revolving credit agreement may be in the form of either base rate loans or

Eurodollar loans. The interest rate for base rate loans is equal to (1) the applicable rate, which ranges from 1.75%
to 2.50%, plus (2) the highest of: (a) the federal funds rate plus 0.5%, (b) the rate of interest in effect for such day
as publicly announced from time to time by agent as its “prime rate,” and (c) the Eurodollar rate for an interest
period of one month plus 1.00%. The interest rate for Eurodollar loans is equal to (1) the applicable rate, which
ranges from 2.75% to 3.50%, plus (2) the London interbank offered rate that appears on Reuters Screen
LIBOR01 Page for deposits in U.S. dollars, or, if such rate is not available, the offered rate on such other page or
service that displays the average British Bankers Association Interest Settlement Rate for deposits in U.S. dollars,
or, if such rate is not available, the average quotations for three major New York money center banks of whom
the agent shall inquire as the “London Interbank Offered Rate” for deposits in U.S. dollars. At December 31,
2010, amounts borrowed under our new revolving credit agreement bore interest at the Eurodollar rate of 3.77%.

The credit agreement contains customary negative covenants including, but not limited to, restrictions on

our and our subsidiaries’ ability to: incur indebtedness; grant liens; pay dividends and make other restricted

51

payments; make investments; make fundamental changes; enter into swap contracts and forward sales contracts;
dispose of assets; change the nature of their business; and enter into transactions with their affiliates. The
negative covenants are subject to certain exceptions as specified in the credit agreement. The credit agreement
also contains certain affirmative covenants, including, but not limited to the following financial covenants:
(1) the ratio of funded debt to EBITDAX (net income, excluding any non-cash revenue or expense associated
with swap contracts resulting from ASC 815, plus without duplication and to the extent deducted from revenues
in determining net income, the sum of (a) the aggregate amount of consolidated interest expense for such period,
(b) the aggregate amount of income, franchise, capital or similar tax expense (other than ad valorem taxes) for
such period, (c) all amounts attributable to depletion, depreciation, amortization and asset or goodwill
impairment or writedown for such period, (d) all other non-cash charges, (e) non-cash losses from minority
investments, (f) actual cash distributions received from minority investments, (g) to the extent actually
reimbursed by insurance, expenses with respect to liability on casualty events or business interruption, and (h) all
reasonable transaction expenses related to dispositions and acquisitions of assets, investments and debt and
equity offering, and less non-cash income attributable to equity income from minority investments) for a twelve-
month period may not be greater than 2.00 to 1.00; and (2) the ratio of EBITDAX to interest expense for a
twelve-month period may not be less than 3.00 to 1.00. We were in compliance with all covenants at
December 31, 2010.

In connection with our scheduled spring 2011 borrowing base redetermination completed in March 2011,

Scotia Capital has advised us that it has approved an increase to our borrowing base from the current level of
$65.0 million to $85.0 million. In addition, Scotia has given us a commitment letter providing for an amendment
to our credit facility which would, among other things, increase the maximum commitment to $350.0 million,
provide for an $85.0 million current borrowing base, extend the maturity date to April 2015 and reduce our
average credit spread by 75 basis points per annum from current levels. Both the increase in the borrowing base
to $85.0 million and the other proposed amendments to our existing credit facility will require the approval of
our other current lender and the addition of one or more additional lenders to our bank group. As a result, we
cannot assure you that we will be able to amend our existing credit facility on the terms described above.

During 2010, in conjunction with the repayment of the Bank of America revolving credit facility on

September 30, 2010, we expensed approximately $225,000 in unamortized loan fees associated with this facility,
which is included in interest expense in our consolidated statements of operations for the year ended
December 31, 2010.

We used the proceeds of our borrowings under the credit facilities for the development of our oil and natural
gas properties and other capital expenditures, acquisition opportunities and for other general corporate purposes.

Building Loans. In June 2004, we purchased the office building we occupy in Oklahoma City, Oklahoma,
for $3.7 million. One loan associated with this building matured in March 2006 and bore interest at the rate of
6% per annum, while the other loan matures in June 2011 and bears interest at the rate of 6.5% per annum. The
remaining building loan requires monthly interest and principal payments of approximately $23,000 and is
secured by the Oklahoma City office building and associated land. As of December 31, 2010, approximately $2.4
million was outstanding on this loan.

Capital Expenditures. Our recent capital commitments have been primarily for the execution of our drilling
programs, to fund Grizzly’s delineation drilling program and for acquisitions, primarily in the Permian Basin and
the Niobrara Formation. Our strategy is to continue to (1) increase cash flow generated from our operations by
undertaking new drilling, workover, sidetrack and recompletion projects to exploit our existing properties,
subject to economic and industry conditions, and (2) explore acquisition and disposition opportunities. We have
upgraded our infrastructure and our existing facilities in Southern Louisiana with the goal of increasing operating
efficiencies and volume capacities and lowering lease operating expenses. These upgrades were also intended to
better enable our facilities to withstand future hurricanes with less damage. Additionally, we completed the
reprocessing of 3-D seismic data in one of our principal properties, WCBB and shot 3-D seismic for the first time

52

in our Hackberry field. The new and reprocessed data enables our geophysicists to continue to generate new
prospects and enhance existing prospects in the intermediate zones in the fields, thus creating a portfolio of new
drilling opportunities. In addition, with our acquisition of strategic assets in the Permian Basin in West Texas, we
are required to pay 50% of all drilling costs for drilling activity on such properties. To combat significant
declines in the commodity prices during the second half of 2008, management undertook a series of actions
aimed at reducing capital spending and operating costs. As a result, we reduced our drilling and other capital
activities to a minimum in the fourth quarter of 2008, releasing all rigs in Southern Louisiana and the Permian
and only selectively participating in wells in the Bakken. During 2009, we were not bound by lease obligations
and long term capital commitments relating to the exploration or development of our oil and gas properties. As a
result of the then current economic conditions, we initially reduced our estimated capital activities and
aggressively sought price concessions from our service providers until such time costs were reduced to more
appropriate levels. In June 2009, we restarted our drilling programs. We commenced our 2010 drilling programs
during March 2010.

In our December 31, 2010 reserve reports, 63% of our net reserves were categorized as proved undeveloped.

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 developed reserves, or
both. To realize reserves and increase production, we must continue our exploratory drilling, undertake other
replacement activities or use third parties to accomplish those activities.

Our inventory of prospects includes approximately 29 proved undeveloped drilling locations at WCBB. The

drilling schedule used in our December 31, 2010 reserve report anticipates that all of those wells will be drilled
by 2013. During 2010, we recompleted 72 wells and drilled 23 wells, all of which were completed as producers,
at WCBB for an aggregate cost of $40.9 million. From January 1, 2011 through March 11, 2011, we recompleted
twelve existing wells and drilled two wells at our WCBB field. We currently intend to spend a total of
approximately $36.0 to $38.0 million to drill 20 to 24 wells and recomplete 60 wells in our WCBB field during
2011.

In our East Hackberry field, in 2010, we recompleted ten existing wells and drilled eight wells, all of which

were completed as producers, for an aggregate cost of $20.0 million. From January 1, 2011 through March 11,
2011, we recompleted three existing wells and drilled three wells, two of which are currently drilling, at our East
Hackberry field. We currently intend to drill seven to ten wells and recomplete five wells in our East Hackberry
field in 2011. Total capital expenditures for our East Hackberry field during 2011 are estimated at $24.0 to $26.0
million.

In the Permian Basin, our booked inventory of prospects includes 226 gross (113 net) future development

drilling locations. During 2010, 25 gross (11 net) wells were drilled on this acreage, of which 24 gross (10.7 net)
were completed as producers and one gross (0.5 net) well was waiting on completion. Our aggregate capital
expenditures in the Permian Basin were $29.0 million in 2010, which includes acreage acquisitions. From
January 1, 2011 through March 11, 2011, four gross (two net) wells were recompleted and five gross (2.5 net)
wells were drilled on this acreage, three of which are waiting on completion and two of which are currently
drilling. We currently anticipate that our capital requirements to drill a total of 40 to 42 gross (19 to 20 net) wells
and recomplete ten gross (five net) wells in the Permian Basin in West Texas will be approximately $37.0 to
$39.0 million.

In the Niobrara Formation in Western Colorado, effective April 1, 2010, we acquired leasehold interests for

a total of approximately $7.6 million. In addition, we recompleted one existing well and acquired additional
acreage for an aggregate cost, including acquisition costs, of approximately $8.1 million in 2010. We are in the
process of permitting a 60 square mile 3-D seismic survey and expect to begin shooting in mid-2011. We
currently anticipate that our total capital expenditures in the Niobrara Formation will be approximately $4.0
million in 2011 relating to the seismic survey and drilling of four to five gross wells.

53

During the third quarter of 2006, we purchased a 24.9999% interest in Grizzly. During 2010, we paid
Grizzly $3.7 million in cash calls. As of December 31, 2010, our net investment in Grizzly was approximately
$26.5 million. In addition, we have loaned Grizzly $20.0 million including interest and net of foreign currency
adjustments as of December 31, 2010. Our capital requirements in 2011 for this project are currently estimated to
be approximately $25.6 million, primarily for the expenses associated with the initial preparations of the Algar
Lake SAGD facility and planned drilling activity.

Capital expenditures in 2010 relating to our interest in Thailand were approximately $400,000. Capital
expenditures in 2011 relating to our interest in Thailand are expected to be approximately $1.0 million, which we
believe will be mostly funded from our share of production from the Phu Horm field.

Our total capital expenditures for 2011 are currently estimated to be $127.0 million to $133.0 million,
excluding our anticipated acquisition in the Utica Shale. This is an increase from the $85.8 million spent in 2010
due to improved commodity pricing and cost environment. We intend to continue to monitor pricing and cost
developments and make adjustments to our future capital expenditure programs as warranted.

We believe that our cash on hand and cash flow from operations will be sufficient to meet our normal
recurring operating needs and our WCBB, Hackberry, Permian Basin, Niobrara and Grizzly capital requirements
for the next twelve months. Although we currently anticipate significant free cash flow during 2011, in the event
we elect to further expand or accelerate our drilling programs, complete acquisitions (including our anticipated
acquisition in the Utica Shale) or accelerate our Canadian oil sands project, we may be required to obtain
additional funds which we would seek to do through traditional borrowings, offerings of debt or equity securities
or other means, including the sale of assets. We regularly evaluate new acquisition opportunities. Needed capital
may not be available to us on acceptable terms or at all. If we are unable to obtain funds when needed or on
acceptable terms, we may be required to delay or curtail implementation of our business plan or not be able to
complete acquisitions that may be favorable to us.

Commodity Price Risk

The volatility of the energy markets makes it extremely difficult to predict future oil and natural gas price
movements with any certainty. For example, during the past five years, the West Texas Intermediate posted price
for crude oil has ranged from a low of $30.28 per barrel, or bbl, in December 2008 to a high of $145.31 per barrel
in July 2008. The Henry Hub spot market price of natural gas has ranged from a low of $1.83 per million British
thermal units, or MMBtu, in September 2009 to a high of $15.52 per MMBtu in January 2006. On March 7,
2011, the West Texas Intermediate posted price for crude oil was $105.44 per barrel and the Henry Hub spot
market price of natural gas was $3.93 per MMBtu. Any substantial decline in the price of oil and natural gas will
likely have a material adverse effect on our operations, financial condition and level of expenditures for the
development of our oil and natural gas reserves, and may result in write downs of oil and natural gas properties
due to ceiling test limitations.

To mitigate the effects of commodity price fluctuations, for the period January 2010 through February 2010,
we were party to forward sales contracts for the sale of 3,000 barrels of WCBB production per day at a weighted
average daily price of $54.81 per barrel, before transportation costs and differentials. For the period March 2010
through December 2010, we were party to forward sales contracts for the sale of 2,300 barrels of WCBB
production per day at a weighted average daily price of $58.24 per barrel, before transportation costs and
differentials. In November 2010, we entered into fixed price swaps for 2,000 barrels of oil per day at a weighted
average price of $86.96 per barrel, before transportation costs and differentials, for the period January 2011
through December 2011. Under the 2010 contracts, we delivered approximately 45% of our 2010 production.
Under the 2011 contacts, we have committed to deliver approximately 30% to 33% of our estimated 2011
production. Such arrangements may expose us to risk of financial loss in certain circumstances, including
instances where production is less than expected or oil prices increase. These forward sales contracts and fixed
price swaps are accounted for as cash flow hedges and recorded at fair value pursuant to FASB ASC 815 and
related pronouncements.

Commitments

In connection with the acquisition in 1997 of the remaining 50% interest in the WCBB properties, we
assumed the seller’s (Chevron) obligation to contribute approximately $18,000 per month through March 2004,
to a plugging and abandonment trust and the obligation to plug a minimum of 20 wells per year for 20 years
commencing March 11, 1997. Chevron retained a security interest in production from these properties until
abandonment obligations to Chevron have been fulfilled. Beginning in 2009, we can access the trust for use in
plugging and abandonment charges associated with the property. As of December 31, 2010, the plugging and
abandonment trust totaled approximately $3,129,000. At December 31, 2010, we have plugged 311 wells at
WCBB since we began our plugging program in 1997, which management believes fulfills our current minimum
plugging obligation.

New Accounting Pronouncements

In December 2008, the SEC published a final rule, “Modernization of Oil and Gas Reporting.” The new rule

permits the use of new technologies to determine proved reserves if those technologies have been demonstrated
to lead to reliable conclusions about reserve volumes. The new requirements also will allow companies to
disclose their probable and possible reserves. In addition, the new disclosure requirements require companies to
(a) report the independence and qualifications of its reserve preparer, (b) file reports when a third party is relied
upon to prepare reserve estimates or conducts a reserve audit, and (c) report oil and gas reserves using an average
price based upon the prior 12-month period rather than year end prices. The new requirements are effective for
annual reports on Form 10-K for fiscal years ending on or after December 31, 2009. Early adoption is not
permitted in quarterly reports prior to the first annual report in which the revised disclosures are required. We
adopted this final rule as of December 31, 2009. The adoption of the rule resulted in a lower price used in reserve
calculations and a decrease in 2009 reserves. Updated disclosures are included in Item 2. “Properties—Proved
Oil and Natural Gas Reserves” and Note 21 to our consolidated financial statements included in this report.

In January 2010, the FASB issued Accounting Standards Update 2010-03, “Oil and Gas Reserve Estimation

and Disclosures” (currently codified in FASB ASC Topic 932, “Extractive Activities – Oil & Gas”), or FASB
ASC 932. The purpose of the amendments in this Update is to align the oil and gas reserve estimation and
disclosure requirements of FASB ASC 932 with the requirements in the SEC’s final rule, “Modernization of Oil
and Gas Reporting.” The amendments to FASB ASC 932 are effective for annual reports on Form 10-K for fiscal
years ending on or after December 31, 2009. We adopted FASB ASC 932 effective December 31, 2009, the
impact of which is noted above.

In January 2010, the FASB issued Accounting Standards Update 2010-06, “Improving Disclosures about
Fair Value Measurements,” which provides amendments to FASB ASC Topic 820, “Fair Value Measurements
and Disclosure,” (FASB ASC 820). FASB ASC 820 requires additional disclosures about (a) the different classes

55

of assets and liabilities measured at fair value, (b) the valuation techniques and inputs used, (c) the activity in
Level 3 fair value measurements, and (d) significant transfers between Levels 1, 2 and 3. The updated guidance is
effective for annual and interim periods beginning after December 15, 2009. We adopted FASB ASC 820
effective January 1, 2010. The adoption did not have a material impact on our consolidated financial statements.

In December 2010, the FASB issued Accounting Standards Update 2010-29, “Business Combinations:
Disclosure of Supplementary Pro Forma Information for Business Combinations” (currently codified in FASB
ASC Topic 805, “Business Combinations”), or FASB ASC 805. The purpose of the amendments in this update is
to specify that if a public entity presents comparative financial statements, the entity should disclose revenue and
earnings of the combined entity as though the business combination that occurred during the current year had
occurred as of the beginning of the comparable prior annual reporting period only. The amendments in this
update also expand the supplemental pro forma disclosures under FASB ASC 805 to include a description of the
nature and amount of material, nonrecurring pro forma adjustments directly attributable to the business
combination included in the reported pro forma revenue and earnings. The amendments to FASB ASC 805 are
effective prospectively for business combinations for which the acquisition date is on or after the beginning of
the first annual reporting period beginning on or after December 15, 2010. The adoption did not have an
immediate impact on our consolidated financial statements.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our revenues, operating results, profitability, future rate of growth and the carrying value of our oil and
natural gas properties depend primarily upon the prevailing prices for oil and natural gas. Historically, oil and
natural gas prices have been volatile and are subject to fluctuations in response to changes in supply and demand,
market uncertainty and a variety of additional factors, including: worldwide and domestic supplies of oil and
natural gas; the level of prices, and expectations about future prices, of oil and natural gas; the cost of exploring
for, developing, producing and delivering oil and natural gas; the expected rates of declining current production;
weather conditions, including hurricanes, that can affect oil and natural gas operations over a wide area; the level
of consumer demand; the price and availability of alternative fuels; technical advances affecting energy
consumption; risks associated with operating drilling rigs; the availability of pipeline capacity; the price and level
of foreign imports; domestic and foreign governmental regulations and taxes; the ability of the members of the
Organization of Petroleum Exporting Countries to agree to and maintain oil price and production controls;
political instability or armed conflict in oil and natural gas producing regions; and the overall economic
environment.

These factors and the volatility of the energy markets make it extremely difficult to predict future oil and

natural gas price movements with any certainty. For example, during the past five years, the West Texas
Intermediate posted price for crude oil has ranged from a low of $30.28 per barrel, or bbl, in December 2008 to a
high of $145.31 per barrel in July 2008. The Henry Hub spot market price of natural gas has ranged from a low
of $1.83 per million British thermal units, or MMBtu, in September 2009 to a high of $15.52 per MMBtu in
January 2006. On March 7, 2011, the West Texas Intermediate posted price for crude oil was $105.44 per barrel
and the Henry Hub spot market price of natural gas was $3.93 per MMBtu. Any substantial decline in the price
of oil and natural gas will likely have a material adverse effect on our operations, financial condition and level of
expenditures for the development of our oil and natural gas reserves, and may result in write downs of oil and
natural gas properties due to ceiling test limitations.

For the period January 2010 through February 2010, we were party to forward sales contracts for the sale of

3,000 barrels of WCBB production per day at a weighted average daily price of $54.81 per barrel, before
transportation costs and differentials. For the period March 2010 through December 2010, we were party to
forward sales contracts for the sale of 2,300 barrels of WCBB production per day at a weighted average daily
price of $58.24 per barrel, before transportation costs and differentials. In November 2010, we entered into fixed
price swaps for 2,000 barrels of oil per day at a weighted average price of $86.96 per barrel, before transportation
costs and differentials, for the period January 2011 through December 2011. Under the 2010 contracts, we

56

delivered approximately 45% of our 2010 production. Under the 2011 contracts, we have committed to deliver
approximately 30% to 33% of our estimated 2011 production. Such arrangements may expose us to risk of
financial loss in certain circumstances, including instances where production is less than expected or oil prices
increase. These forward sales contracts and fixed price swaps are accounted for as cash flow hedges and recorded
at fair value pursuant to FASB ASC 815 and related pronouncements. At December 31, 2010, we had a net
liability derivative position of $4.7 million related to our fixed price swaps. Utilizing actual derivative
contractual volumes, a 10% increase in underlying commodity prices would have reduced the fair value of these
instruments by approximately $6.8 million, while a 10% decrease in underlying commodity prices would have
increased the fair value of these instruments by $6.8 million. However, any realized derivative gain or loss would
be substantially offset by a decrease of increase, respectively, in the actual sales value of production covered by
the derivative instrument.

Our new revolving credit facility is structured under floating rate terms, as advances under this facility may

be in the form of either base rate loans or Eurodollar loans. As such, our interest expense is sensitive to
fluctuations in the prime rates in the U.S. or, if the Eurodollar rates are elected, the Eurodollar rates. At
December 31, 2010, amounts borrowed under our new revolving credit agreement bore interest at the Eurodollar
rate of 3.77%. Based on the current debt structure, a 1% increase in interest rates would increase interest expense
by approximately $495,000 per year, based on $49.5 million outstanding under our credit facility as of
December 31, 2010. As of December 31, 2010, we did not have any interest rate swaps to hedge our interest
risks.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Control and Procedures. Under the direction of our Chief Executive Officer and

Vice President and Chief Financial Officer, we have established disclosure controls and procedures that are
designed to ensure that information required to be disclosed by us in the reports that we file or submit under the
Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods
specified in the SEC’s rules and forms. The disclosure controls and procedures are also intended to ensure that
such information is accumulated and communicated to management, including our Chief Executive Officer and
Vice President and Chief Financial Officer, as appropriate to allow timely decisions regarding required
disclosures.

As of December 31, 2010, an evaluation was performed under the supervision and with the participation of

management, including our Chief Executive Officer and Vice President and Chief Financial Officer, of the
effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rule 13a-15(b)
under the Securities Exchange Act of 1934. Based upon our evaluation, our Chief Executive Officer and Vice
President and Chief Financial Officer have concluded that as of December 31, 2010, our disclosure controls and
procedures are effective.

Changes in Internal Control over Financial Reporting. There have not been any changes in our internal

control over financial reporting that occurred during our last fiscal quarter that have materially affected, or are
reasonably likely to materially affect, internal controls over financial reporting.

Management’s Report on Internal Control Over Financial Reporting

Management is responsible for the fair presentation of the consolidated financial statements of Gulfport
Energy Corporation. Management is also responsible for establishing and maintaining a system of adequate
internal controls over financial reporting as defined in Rule 13a-15(f) and 15d-15(f) under the Securities
Exchange Act of 1934, as amended. These internal controls are designed to provide reasonable assurance that the
reported financial information is presented fairly, that disclosures are adequate and that the judgments inherent in
the preparation of financial statements are reasonable. There are inherent limitations in the effectiveness of any
system of internal control, including the possibility of human error and overriding of controls. Consequently, an
effective internal control system can only provide reasonable, not absolute, assurance with respect to reporting
financial information.

Management conducted an evaluation of the effectiveness of our internal control over financial reporting
based on the framework in Internal Control—Integrated Framework issued by the Committee of Sponsoring
Organizations of the Treadway Commission. Based on its evaluation under the framework in Internal Control—
Integrated Framework, management did not identify any material weaknesses in our internal control over
financial reporting and concluded that our internal control over financial reporting was effective as of
December 31, 2010.

Grant Thornton LLP, the independent registered public accounting firm that audited our financial statements

for the year ended December 31, 2010 included with this Annual Report on Form 10-K, has also audited our
internal control over financial reporting as of December 31, 2010, as stated in their accompanying report.

Report of Independent Registered Public Accounting Firm

Board of Directors and Stockholders
Gulfport Energy Corporation:

We have audited internal control over financial reporting of Gulfport Energy Corporation and Subsidiaries (the
“Company”) as of December 31, 2010, based on criteria established in Internal Control—Integrated Framework
issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). The Company’s
management is responsible for maintaining effective internal control over financial reporting and for its
assessment of the effectiveness of internal control over financial reporting, included in the accompanying
Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion
on the Company’s internal control over financial reporting based on our audit.

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

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

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

In our opinion, Gulfport Energy Corporation and Subsidiaries maintained, in all material respects, effective
internal control over financial reporting as of December 31, 2010, based on criteria established in Internal
Control—Integrated Framework issued by COSO.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board
(United States), the consolidated balance sheets of Gulfport Energy Corporation and Subsidiaries as of
December 31, 2010 and 2009, and the related consolidated statements of operations, stockholders’ equity and
comprehensive income (loss) and cash flows for each of the three years in the period ended December 31, 2010
and our report dated March 14, 2011 expressed an unqualified opinion.

Report of Independent Registered Public Accounting Firm

Board of Directors and Stockholders
Gulfport Energy Corporation:

We have audited the accompanying consolidated balance sheets of Gulfport Energy Corporation and Subsidiaries
(the “Company”) as of December 31, 2010 and 2009, and the related consolidated statements of operations,
stockholders’ equity and comprehensive income (loss) and cash flows for each of the three years in the period
ended December 31, 2010. 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 consolidated financial statements referred to above present fairly, in all material respects, the
financial position of Gulfport Energy Corporation and Subsidiaries as of December 31, 2010 and 2009, and the
results of their operations and their cash flows for each of the three years in the period ended December 31, 2010,
in conformity with accounting principles generally accepted in the United States of America.

As discussed in Note 1, the Company changed its method of estimating oil and gas reserves and related
disclosures in 2009.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board
(United States), Gulfport Energy Corporation and Subsidiaries’ internal control over financial reporting as of
December 31, 2010, based on the criteria established in Internal Control—Integrated Framework issued by the
Committee of Sponsoring Organizations of the Treadway Commission (COSO) and our report dated March 14,
2011 expressed an unqualified opinion.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Amounts rounded to nearest thousand)

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Business

Gulfport Energy Corporation (“Gulfport” or the “Company”) is an independent oil and gas exploration,
development and production company with its principal properties located in the Louisiana Gulf Coast, in West
Texas in the Permian Basin and in Western Colorado in the Niobrara Formation and has investments in
companies operating in Canada and Thailand.

Cash and Cash Equivalents

The Company considers all highly liquid investments with an original maturity of three months or less to be

cash equivalents for purposes of the statement of cash flows.

Principles of Consolidation

The consolidated financial statements include the Company and its wholly owned subsidiaries, Grizzly
Holdings Inc., Jaguar Resources LLC, Gator Marine, Inc., Gator Marine Ivanhoe, Inc. and Puma Resources, Inc.
All intercompany balances and transactions are eliminated in consolidation.

Accounts Receivable

The Company’s accounts receivable—oil and gas primarily are from companies in the oil and gas industry.
The majority of its receivables are from two purchasers of the Company’s oil and gas and one operator of certain
of the Company’s properties. Credit is extended based on evaluation of a customer’s payment history and,
generally, collateral is not required. Accounts receivable are due within 30 days and are stated at amounts due
from customers, net of an allowance for doubtful accounts when the Company believes collection is doubtful.
Accounts outstanding longer than the contractual payment terms are considered past due. The Company
determines its allowance by considering a number of factors, including the length of time accounts receivable are
past due, the Company’s previous loss history, the customer’s current ability to pay its obligation to the
Company, amounts which may be obtained by an offset against production proceeds due the customer and the
condition of the general economy and the industry as a whole. The Company writes off specific accounts
receivable when they become uncollectible, and payments subsequently received on such receivables are credited
to the allowance for doubtful accounts. No allowance was deemed necessary at December 31, 2010 and
December 31, 2009.

Oil and Gas Properties

The Company uses the full cost method of accounting for oil and gas operations. Accordingly, all costs,

including nonproductive costs and certain general and administrative costs directly associated with acquisition,
exploration and development of oil and gas properties, are capitalized. Under the full cost method of accounting,
the Company is required to perform a ceiling test each quarter. The test determines a limit, or ceiling, on the
book value of the oil and gas properties. Net capitalized costs are limited to the lower of unamortized cost net of
deferred income taxes or the cost center ceiling. The cost center ceiling is defined as the sum of (a) estimated
future net revenues, discounted at 10% per annum, from proved reserves, based on the 12-month unweighted
average of the first-day-of-the-month price for 2010 and 2009, and prior to 2009, unescalated year-end prices and
costs, adjusted for any contract provisions or financial derivatives, if any, that hedge the Company’s oil and
natural gas revenue, and excluding the estimated abandonment costs for properties with asset retirement

(Amounts rounded to nearest thousand)

obligations recorded on the balance sheet, (b) the cost of properties not being amortized, if any, and (c) the lower
of cost or market value of unproved properties included in the cost being amortized, including related deferred
taxes for differences between the book and tax basis of the oil and natural gas properties. If the net book value,
including related deferred taxes, exceeds the ceiling, an impairment or noncash writedown is required.

Such capitalized costs, including the estimated future development costs and site remediation costs of
proved undeveloped properties are depleted by an equivalent units-of-production method, converting gas to
barrels at the ratio of six Mcf of gas to one barrel of oil. No gain or loss is recognized upon the disposal of oil and
gas properties, unless such dispositions significantly alter the relationship between capitalized costs and proven
oil and gas reserves. Oil and gas properties not subject to amortization consist of the cost of unproved leaseholds
and totaled $16,778,000 and $17,521,000 at December 31, 2010 and December 31, 2009, respectively. These
costs are reviewed quarterly by management for impairment. If impairment has occurred, the portion of cost in
excess of the current value is transferred to the cost of oil and gas properties subject to amortization. Factors
considered by management in its impairment assessment include drilling results by Gulfport and other operators,
the terms of oil and gas leases not held by production, and available funds for exploration and development.

The Company accounts for its abandonment and restoration liabilities under FASB ASC Topic 410, “Asset

Retirement and Environmental Obligations” (“FASB ASC 410”), which requires the Company to record a
liability equal to the fair value of the estimated cost to retire an asset. The asset retirement liability is recorded in
the period in which the obligation meets the definition of a liability, which is generally when the asset is placed
into service. When the liability is initially recorded, the Company increases the carrying amount of oil and
natural gas properties by an amount equal to the original liability. The liability is accreted to its present value
each period, and the capitalized cost is included in capitalized costs and depreciated consistent with depletion of
reserves. Upon settlement of the liability or the sale of the well, the liability is reversed. These liability amounts
may change because of changes in asset lives, estimated costs of abandonment or legal or statutory remediation
requirements.

Other Property and Equipment

Depreciation of other property and equipment is provided on a straight-line basis over estimated useful lives

of the related assets, which range from 3 to 30 years.

Foreign Currency

The U.S. dollar is the functional currency for Gulfport’s consolidated operations. However, the Company
has an equity investment in a Canadian entity whose functional currency is the Canadian dollar. The assets and
liabilities of the Canadian investment are translated into U.S. dollars based on the current exchange rate in effect
at the balance sheet dates. Canadian income and expenses are translated at average rates for the periods
presented. Translation adjustments have no effect on net income and are included in accumulated other
comprehensive income in stockholders’ equity. The following table presents the balances of the Company’s
cumulative translation adjustments included in accumulated other comprehensive income.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
DECEMBER 31, 2010, 2009 AND 2008
(Amounts rounded to nearest thousand)

Net Income per Common Share

Basic net income per common share is computed by dividing income attributable to common stock by the
weighted average number of common shares outstanding for the period. Diluted net income per common share
reflects the potential dilution that could occur if options or other contracts to issue common stock were exercised
or converted into common stock. Potential common shares are not included if their effect would be anti-dilutive.
Calculations of basic and diluted net income per common share are illustrated in Note 13.

Income Taxes

Gulfport uses the asset and liability method of accounting for income taxes, under which deferred tax assets
and liabilities are recognized for the future tax consequences of (1) temporary differences between the financial
statement carrying amounts and the tax bases of existing assets and liabilities and (2) operating loss and tax credit
carryforwards. Deferred income tax assets and liabilities are based on enacted tax rates applicable to the future
period when those temporary differences are expected to be recovered or settled. The effect of a change in tax
rates on deferred tax assets and liabilities is recognized in income during the period the rate change is enacted.
Deferred tax assets are recognized as income in the year in which realization becomes determinable. A valuation
allowance is provided for deferred tax assets when it is more likely than not the deferred tax assets will not be
realized.

The company adopted the provisions of FASB ASC Topic 740 as of January 1, 2007. The Company is
subject to U.S. federal income tax as well as income tax of multiple jurisdictions. The Company’s 1996 – 2009
U.S. federal and state income tax returns remain open to examination by tax authorities, due to net operating
losses. As of December 31, 2010, the Company has no unrecognized tax benefits that would have a material
impact on the effective rate. The Company recognizes interest and penalties related to income tax matters as
interest expense and general and administrative expenses, respectively. For the year ended December 31, 2010,
there is no interest or penalties associated with uncertain tax positions in the Company’s consolidated financial
statements.

Revenue Recognition

Gas revenues are recorded in the month produced and delivered to the purchaser using the entitlement

method, whereby any production volumes received in excess of the Company’s ownership percentage in the
property are recorded as a liability. If less than Gulfport’s entitlement is received, the underproduction is
recorded as a receivable. There is no such liability or asset recorded at December 31, 2010 and 2009 because the
Company has no imbalances. Oil revenues are recognized when ownership transfers, which occurs in the month
produced.

Investments—Equity Method

Investments in entities greater than 20% and less than 50% are accounted for under the equity method.

Under the equity method, the Company’s share of investees’ earnings or loss is recognized in the statement of
operations. The Company reviews its investments to determine if a loss in value which is other than a temporary
decline has occurred. If such loss has occurred, the Company recognizes an impairment provision. There was no
impairment of equity method investments at December 31, 2010 or 2009.

(Amounts rounded to nearest thousand)

Accounting for Stock-Based Compensation

The Company accounts for stock-based compensation in accordance with the provisions of FASB ASC

Topic 718, “Compensation—Stock Compensation” (“FASB ASC 718”). FASB ASC 718 requires share-based
payments to employees, including grants of employee stock options, to be recognized as equity or liabilities at
the fair value on the date of grant and to be expensed over the applicable vesting period.

Accounting for Derivative Instruments and Hedging Activities

The Company may seek to reduce its exposure to unfavorable changes in oil prices by utilizing energy

swaps and collars, or fixed-price contracts. The Company follows the provisions of FASB ASC 815,
“Derivatives and Hedging” (“FASB ASC 815”) as amended. It requires that all derivative instruments be
recognized as assets or liabilities in the statement of financial position, measured at fair value.

The Company estimates the fair value of all derivative instruments using established index prices and other

sources. These values are based upon, among other things, futures prices, correlation between index prices and
the Company’s realized prices, time to maturity and credit risk. The values reported in the consolidated financial
statements change as these estimates are revised to reflect actual results, changes in market conditions or other
factors.

The accounting for changes in the fair value of a derivative depends on the intended use of the derivative
and the resulting designation. Designation is established at the inception of a derivative, but re-designation is
permitted. For derivatives designated as cash flow hedges and meeting the effectiveness guidelines of FASB
ASC 815, changes in fair value are recognized in accumulated other comprehensive income until the hedged item
is recognized in earnings. Hedge effectiveness is measured at least quarterly based on the relative changes in fair
value between the derivative contract and the hedged item over time. Any change in fair value resulting from
ineffectiveness is recognized immediately in earnings.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the

United States of America requires management to make estimates, judgments and assumptions that affect the
reported amounts of assets and liabilities as of the date of the financial statements and revenues and expenses
during the reporting period. Actual results could differ materially from those estimates. Significant estimates
with regard to these financial statements include the estimate of proved oil and gas reserve quantities and the
related present value of estimated future net cash flows there from, the amount and timing of asset retirement
obligations, the realization of deferred tax assets and the realization of future net operating loss carryforwards
available as reductions of income tax expense. The estimate of the Company’s oil and gas reserves is used to
compute depletion, depreciation, amortization and impairment of oil and gas properties.

Recent Accounting Pronouncements

In December 2008, the Securities and Exchange Commission published a Final Rule, “Modernization of Oil

and Gas Reporting.” The new rule permits the use of new technologies to determine proved reserves if those
technologies have been demonstrated to lead to reliable conclusions about reserve volumes. The new
requirements also will allow companies to disclose their probable and possible reserves. In addition, the new
disclosure requirements require companies to (a) report the independence and qualifications of its reserve

F-10

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(Amounts rounded to nearest thousand)

preparer, (b) file reports when a third party is relied upon to prepare reserve estimates or conducts a reserve audit,
and (c) report oil and gas reserves using an average price based upon the prior 12 month period rather than year
end prices. The new requirements were effective for annual reports on Form 10-K for fiscal years ending on or
after December 31, 2009. The Company adopted the Final Rule as of December 31, 2009. The adoption of the
rule resulted in a lower price used in reserve calculations and a decrease in 2009 reserves. See Item 2. Properties
and Note 21 for further discussion of the impact of implementation.

In January 2010, the FASB issued Accounting Standards Update 2010-03, “Oil and Gas Reserve Estimation

and Disclosures” (currently codified in FASB ASC Topic 932, “Extractive Activities – Oil & Gas”) (“FASB
ASC 932”). The purpose of the amendments in this Update is to align the oil and gas reserve estimation and
disclosure requirements of FASB ASC 932 with the requirements in the Security and Exchange Commission’s
Final Rule, “Modernization of Oil and Gas Reporting.” The amendments to FASB ASC 932 are effective for
annual reports on Form 10-K for fiscal years ending on or after December 31, 2009. The impact of the adoption
of FASB ASC 932 is noted above.

In January 2010, the FASB issued Accounting Standards Update 2010-06, “Improving Disclosures about
Fair Value Measurements,” which provides amendments to FASB ASC Topic 820, “Fair Value Measurements
and Disclosure” (“FASB ASC 820”). FASB ASC 820 requires additional disclosures about (a) the different
classes of assets and liabilities measured at fair value, (b) the valuation techniques and inputs used, (c) the
activity in Level 3 fair value measurements, and (d) significant transfers between Levels 1, 2 and 3. The updated
guidance is effective for annual and interim periods beginning after December 15, 2009. The Company adopted
FASB ASC 820 effective January 1, 2010. The adoption did not have a material impact on the Company’s
consolidated financial statements.

In December 2010, the FASB issued Accounting Standards Update 2010-29, “Business Combinations:
Disclosure of Supplementary Pro Forma Information for Business Combinations” (currently codified in FASB
ASC Topic 805, “Business Combinations”) (“FASB ASC 805”). The purpose of the amendments in this update
is to specify that if a public entity presents comparative financial statements, the entity should disclose revenue
and earnings of the combined entity as though the business combination that occurred during the current year had
occurred as of the beginning of the comparable prior annual reporting period only. The amendments in this
update also expand the supplemental pro forma disclosures under FASB ASC 805 to include a description of the
nature and amount of material, nonrecurring pro forma adjustments directly attributable to the business
combination included in the reported pro forma revenue and earnings. The amendments to FASB ASC 805 are
effective prospectively for business combinations for which the acquisition date is on or after the beginning of
the first annual reporting period beginning on or after December 15, 2010. The adoption did not have an

At December 31, 2008, the net book value of the Company’s oil and natural gas properties, less related
deferred income taxes, was above the calculated ceiling as a result of reduced commodity prices at December 31,
2008. As a result, the Company was required to record an impairment of its oil and natural gas properties under
the full cost method of accounting in the amount of $272.7 million for the year ended December 31, 2008. No
impairment of oil and natural gas properties was required for the years ended December 31, 2010 and
December 31, 2009.

Included in oil and natural gas properties at December 31, 2010 and December 31, 2009 is the cumulative

capitalization of $18,126,000 and $14,009,000, respectively, in general and administrative costs incurred and
capitalized to the full cost pool. General and administrative costs capitalized to the full cost pool represent
management’s estimate of costs incurred directly related to exploration and development activities such as
geological and other administrative costs associated with overseeing the exploration and development activities.
All general and administrative costs not directly associated with exploration and development activities were
charged to expense as they were incurred. Capitalized general and administrative costs were approximately
$4,117,000, $3,395,000 and $4,645,000 for the years ended December 31, 2010, 2009 and 2008, respectively.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
DECEMBER 31, 2010, 2009 AND 2008
(Amounts rounded to nearest thousand)

(1) In March 2005, Gulfport entered into a three-year secured credit agreement with Bank of America, N.A.
providing for a revolving credit facility. The credit agreement was subsequently amended and restated from time
to time and, among other things, the maturity date was extended to April 1, 2011. Borrowings under the
revolving credit facility were subject to a borrowing base limitation, which was initially set at $18.0 million,
subject to adjustment. Effective July 19, 2007, the credit facility was increased to $150.0 million and effective
December 20, 2007, the amount available under the borrowing base limitation was increased to $90.0 million.

On August 31, 2009, the lender completed its periodic redetermination of the Company’s borrowing base
giving consideration to the Company’s year-end 2008 and mid-year 2009 reserve information and the lender’s
then current pricing decks, among other factors. As a result of this redetermination, the Company’s available
borrowing base was reset at $45.0 million, primarily in response to significant declines in commodity prices. The
Company’s outstanding principal balance at the effective time of this redetermination was approximately $59.0
million. The approximately $14.0 million of outstanding borrowings under the credit facility in excess of the new
borrowing base was converted into a term loan as of August 31, 2009. An initial $2.0 million payment was made
on the term loan at that time and the Company agreed to make additional monthly payments of $1.0 million
commencing on September 30, 2009, with all unpaid amounts due on March 31, 2010. The Company paid the
outstanding balance of the term loan in full in February 2010.

Outstanding borrowings under the term loan accrued interest at the Eurodollar rate (as defined in the credit

agreement) plus 4.0% or, at the option of the Company, at the base rate (which was the highest of the lender’s
prime rate, the Federal funds rate plus half of 1%, and the one-month Eurodollar rate plus 1%) plus 3%. Effective
August 31, 2009, the Company also agreed to an adjustment in the commitment fees, interest rates for revolving
loans and fees for letters of credit under the credit facility. Specifically, the Company agreed to pay
(a) commitment fees ranging from 0.5% to 0.625% (an increase from 0.15% to 0.25%), (b) margin interest rates
ranging from 2.75% to 3.50% for Eurodollar loans (an increase from 1.25% to 2.0%), (c) margin interest rates
ranging from 1.75% to 2.5% for base rate loans (an increase from 1.25% to 2.0%), and (d) letter of credit fees at
the margin interest rates for Eurodollar loans, in each case based on the Company’s utilization percentage. In
addition, the Company agreed to limitations on certain dispositions and investments and to mandatory
prepayments of the loans from the net cash proceeds of specified asset sales and other events.

The Company’s obligations under the credit facility were collateralized by a lien on substantially all of the

Company’s Louisiana and West Texas assets and were guaranteed by its subsidiaries. The restated credit
agreement contained certain affirmative and negative covenants, including, but not limited to the following
financial covenants: (a) the ratio of funded debt to EBITDAX (net income before deductions for taxes, excluding
unrealized gains and losses related to trading securities and commodity hedges, plus depreciation, depletion,
amortization and interest expense, plus exploration costs deducted in determining net income under full cost
accounting) for a twelve-month period could not be greater than 2.00 to 1.00; and (b) the ratio of EBITDAX to
interest expense for a twelve-month period could not be less than 3.00 to 1.00.

On September 30, 2010, the Company entered into a $100 million senior secured revolving credit agreement

with The Bank of Nova Scotia, as administrative agent and letter of credit issuer and lead arranger, and Amegy
Bank National Association. The new revolving credit facility matures on September 30, 2013 and has an initial
borrowing base availability of $50.0 million, which was increased to $65.0 million effective December 24, 2010.
As of December 31, 2010, the Company had an outstanding balance of $49.5 million drawn under the credit
agreement, which is included in long-term debt, net of current maturities, on the accompanying consolidated
balance sheets. The amounts borrowed under the credit agreement were used to repay all of the Company’s

F-18

GULFPORT ENERGY CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
DECEMBER 31, 2010, 2009 AND 2008
(Amounts rounded to nearest thousand)

outstanding indebtedness under its prior revolving credit facility ($42.0 million) and term loan ($2.5 million),
each with Bank of America, N.A., as administrative agent, and for general corporate purposes. The new credit
agreement is secured by substantially all of the Company’s assets. The Company’s wholly-owned subsidiaries
guaranteed the obligations of the Company under the credit agreement.

Advances under the credit agreement may be in the form of either base rate loans or eurodollar loans. The
interest rate for base rate loans is equal to (1) the applicable rate, which ranges from 1.75% to 2.50%, plus (2) the
highest of: (a) the federal funds rate plus 0.5%, (b) the rate of interest in effect for such day as publicly
announced from time to time by agent as its “prime rate,” and (c) the eurodollar rate for an interest period of one
month plus 1.00%. The interest rate for eurodollar loans is equal to (1) the applicable rate, which ranges from
2.75% to 3.50%, plus (2) the London interbank offered rate that appears on Reuters Screen LIBOR01 Page for
deposits in U.S. dollars, or, if such rate is not available, the offered rate on such other page or service that
displays the average British Bankers Association Interest Settlement Rate for deposits in U.S. dollars, or, if such
rate is not available, the average quotations for three major New York money center banks of whom the agent
shall inquire as the “London Interbank Offered Rate” for deposits in U.S. dollars. At December 31, 2010,
amounts borrowed under the credit agreement bore interest at the Eurodollar rate (3.77%).

The credit agreement contains customary negative covenants including, but not limited to, restrictions on the

Company’s and its subsidiaries’ ability to: incur indebtedness; grant liens; pay dividends and make other
restricted payments; make investments; make fundamental changes; enter into swap contracts and forward sales
contracts; dispose of assets; change the nature of their business; and enter into transactions with their affiliates.
The negative covenants are subject to certain exceptions as specified in the credit agreement. The credit
agreement also contains certain affirmative covenants, including, but not limited to the following financial
covenants: (1) the ratio of funded debt to EBITDAX (net income, excluding any non-cash revenue or expense
associated with swap contracts resulting from ASC 815, plus without duplication and to the extent deducted from
revenues in determining net income, the sum of (a) the aggregate amount of consolidated interest expense for
such period, (b) the aggregate amount of income, franchise, capital or similar tax expense (other than ad valorem
taxes) for such period, (c) all amounts attributable to depletion, depreciation, amortization and asset or goodwill
impairment or writedown for such period, (d) all other non-cash charges, (e) non-cash losses from minority
investments, (f) actual cash distributions received from minority investments, (g) to the extent actually
reimbursed by insurance, expenses with respect to liability on casualty events or business interruption, and (h) all
reasonable transaction expenses related to dispositions and acquisitions of assets, investments and debt and
equity offering, and less non-cash income attributable to equity income from minority investments) for a twelve-
month period may not be greater than 2.00 to 1.00; and (2) the ratio of EBITDAX to interest expense for a
twelve-month period may not be less than 3.00 to 1.00. The Company was in compliance with all covenants at
December 31, 2010.

In conjunction with the repayment of the Bank of America credit facilities on September 30, 2010, the
Company expensed approximately $225,000 in unamortized loan fees associated with the Bank of America
revolving credit facility, which is included in interest expense in the accompanying consolidated statements of
operations.

On July 10, 2006, Gulfport entered into a $5 million term loan agreement with Bank of America, N.A.
related to the purchase of new gas compressor units. The loan began amortizing quarterly on March 31, 2007 on
a straight-line basis over seven years based on the outstanding principal balance at December 31, 2006. The
Company made quarterly principal payments of approximately $176,000. Amounts borrowed bore interest at

DECEMBER 31, 2010, 2009 AND 2008
(Amounts rounded to nearest thousand)

Bank of America Prime. The Company made quarterly interest payments on amounts borrowed under the
agreement. The Company’s obligations under the agreement were collateralized by a lien on the compressor
units. On September 30, 2010, the Company repaid this loan in full with borrowings under the new credit
agreement discussed above.

(2) In June 2004, the Company purchased the office building it occupies in Oklahoma City, Oklahoma, for

$3.7 million. One loan associated with this building matured in March 2006 and bore interest at the rate of
6% per annum, while the other loan matures in June 2011 and bears interest at the rate of 6.5% per annum. The
remaining building loan requires monthly interest and principal payments of approximately $23,000 and is
secured by the Oklahoma City office building and associated land.

8. COMMON STOCK OPTIONS, RESTRICTED STOCK, WARRANTS AND CHANGES IN

CAPITALIZATION

Options

The Company sponsors the 1999 Stock Option Plan (the “Plan”), which is administered by the

Compensation Committee (the “Committee”) of the Board of Directors of the Company. Under the terms of the
Plan, the Committee could determine: to which eligible participants options shall be granted, the number of
shares covered by such options, the purchase price or exercise price of such options, the vesting period of such
options and the exercisable period of such options. Eligible participants are defined as all directors of the
Company, all officers of the Company and all key employees of the Company with a customary work week of at
least 40 hours in the employ of the Company. The maximum number of shares for which options could be
granted under the Plan, as adjusted for changes in capitalization which have taken place since the Plan’s
adoption, was 883,000. The Company has granted 627,337 options for the purchase of shares of the Company’s
common stock under the Plan as of December 31, 2010. No additional securities will be issued under the Plan
other than upon exercise of options that are outstanding.

The Company replaced the Plan in January 2005 with the 2005 Stock Incentive Plan (“2005 Plan”), which is

administered by the Committee. Under the terms of the 2005 Plan, the Committee may determine when options
shall be granted, to which eligible participants options shall be granted, the number of shares covered by such
options, the purchase price or exercise price of such options, the vesting periods of such options and the
exercisable period of such options. Eligible participants are defined as employees, consultants, and directors of
the Company.

On April 20, 2006, the Company amended and restated the 2005 Plan to (i) include (a) Incentive Stock
Options, (b) Nonstatutory Stock Options, (c) Restricted Awards (Restricted Stock and Restricted Stock Units),
(d) Performance Awards and (e) Stock Appreciation Rights and (ii) increase the maximum aggregate amount of
common stock that may be issued under the 2005 Plan from 1,904,606 shares to 3,000,000 shares, including the
627,337 shares underlying options granted to employees under the Plan prior to adoption of the 2005 Plan. As of
December 31, 2010, the Company has granted 997,269 options for the purchase of shares of the Company’s
common stock under the 2005 Plan.

Restricted Stock

On March 13, 2008, the Company granted 6,666 shares of restricted common stock of the Company, of
which 740 shares vested on April 1, 2008 with the remaining shares vesting over 36 equal monthly installments

the Company. The shares vest over twelve equal quarterly installments beginning on September 17, 2008. On
September 15, 2008, the Company granted 10,000 shares of restricted common stock of the Company. The
shares vest over twelve equal quarterly installments beginning on September 17, 2008. On December 5, 2008, the

quarterly installments beginning on December 17, 2008.

On November 3, 2009, the Company granted 13,332 shares of restricted common stock of the Company.

The shares vest over twelve equal quarterly installments beginning on December 17, 2009.

On March 8, 2010, the Company granted 66,667 shares of restricted common stock of the Company to
employees of the Company at a fair value of approximately $662,000. The shares vest over twelve substantially
equal quarterly installments beginning on March 18, 2010. On November 3, 2010, the Company granted 45,000
shares of restricted common stock of the Company to employees of the Company at a fair value of approximately
$783,000. The shares vest annually over five years, with 3,000 vesting the first year, 6,000 vesting the second
year, 9,000 vesting the third year, 12,000 vesting the fourth year, and 15,000 vesting the fifth year. All shares of
restricted common stock of the Company were granted under the amended and restated 2005 Plan.

Sale of Common Stock

On May 19, 2010, the Company sold 1,481,481 shares of its common stock in an underwritten public
offering at a public offering price of $13.50 per share less the underwriting discount. On May 25, 2010, the
Company sold an additional 187,022 shares of common stock at the public offering price less the underwriting
discount in connection with the underwriters’ partial exercise of the over-allotment option granted to them by the
Company. The Company received the aggregate net proceeds of approximately $21.6 million from the sale of
these shares after deducting the underwriting discount and before offering expenses. A portion of the net
proceeds from the offering was used to fund the Company’s Niobrara Formation and Permian Basin acquisitions
as discussed in Note 2. The remaining net proceeds from this offering were used for general corporate purposes,
including expenditures associated with the Company’s 2010 drilling programs.

Private Placement Offering

In March 2002, the Company completed a private placement offering of 10,000 units. Each unit consisted of

(i) one share of Cumulative Preferred Stock, Series A, of the Company (the “Preferred”) and (ii) a warrant to
purchase up to 250 shares of common stock, par value $0.01 per share, of the Company (the “Warrants”).
Holders of the Preferred were entitled to receive dividends at the rate of 12% of the liquidation preference per
annum payable quarterly in cash or, at the option of the Company for all quarters ending on or prior to March 31,
2004, payable in whole or in part in additional shares of Preferred at the rate of 15% of the liquidation preference
per annum. All Preferred shares were redeemed in 2005.

The 2,322,962 Warrants issued have a term of ten years and a current exercise price of $1.19 per share of

common stock subject to adjustment. The Company granted to holders of the Warrants certain demand and
piggyback registration rights with respect to shares of common stock issuable upon exercise of the Warrants. The
Company considered the valuation of the Warrants and did not consider them materially significant. The
Company had 9,050 Warrants outstanding at December 31, 2010 which can be converted into 30,420 shares of
common stock.

STOCK-BASED COMPENSATION

During the years ended December 31, 2010, 2009 and 2008, the Company’s stock-based compensation cost

was $492,000, $529,000 and $1,056,000, respectively, of which the Company capitalized $197,000, $212,000
and $422,000, respectively, relating to its exploration and development efforts, which reduced basic and diluted
earnings per share by $0.01 and $0.01 for the years ended December 31, 2010 and December 31, 2009,
respectively.

The fair value of each option award is estimated on the date of grant using the Black-Scholes option
valuation model. Expected volatilities are based on the historical volatility of the market price of Gulfport’s
common stock over a period of time ending on the grant date. Based upon historical experience of the Company,
the expected term of options granted is equal to the vesting period plus one year. The risk-free rate for periods
within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of the
grant. The 2005 Plan provides that all options must have an exercise price not less than the fair value of the
Company’s common stock on the date of the grant.

No stock options were issued during the years ended December 31, 2010, 2009 and 2008.

The Company has not declared dividends and does not intend to do so in the foreseeable future, and thus did

not use a dividend yield. In each case, the actual value that will be realized, if any, depends on the future
performance of the common stock and overall stock market conditions. There is no assurance that the value an
optionee actually realizes will be at or near the value estimated using the Black-Scholes model.

expensed to lease operating expenses as incurred in 2008 and 2009. The Company recognized the insurance
proceeds in other (income) expense in the accompanying consolidated statements of operations. In September
and October 2009, the Company received additional insurance proceeds of approximately $994,000 related to
damages incurred in the WCBB field as a result of Hurricane Ike and related debris removal. As the costs related
to these repairs and debris removal were incurred in 2009 and expensed to lease operating expense, the Company
recognized the insurance proceeds in lease operating expenses in the accompanying consolidated statements of
operations.

11. FAIR VALUE OF FINANCIAL INSTRUMENTS

The carrying amounts on the accompanying consolidated balance sheet for cash and cash equivalents,
accounts receivable, accounts payable and accrued liabilities, and current and long-term debt are carried at cost,
which approximates market value.

The fair value of the derivative instruments is computed based on the difference between the prices provided
by the fixed-price contracts and forward market prices as of the specified date, as adjusted for basis differentials.
Forward market prices for oil are dependent upon supply and demand factors in such forward market and are
subject to significant volatility.

The Company has an available tax net operating loss carryforward estimated at approximately $52,417,000

as of December 31, 2010. This carryforward will begin to expire in the year 2018. A valuation allowance has
been provided at December 31, 2010, 2009 and 2008 because it is management’s belief, based upon the
Company’s past history of no taxable income and future projections of no taxable income during the
carryforward period, it is more likely than not the net deferred tax assets will not be realized.

The Company had income tax expense of $40,000 and $28,000 related to state income tax for the years

ended December 31, 2010 and 2009, respectively.

For the year ended December 31, 2009, options to purchase 64,889 shares at $9.07 per share and 200,000
shares at $11.20 per share were excluded from the calculation of dilutive earnings per share because they were
anti-dilutive. For the year ended December 31, 2008, all options were excluded from the calculation of dilutive
earnings per share because the Company had a net loss and, therefore, the effect would have been anti-dilutive.
There were no potential shares of common stock that were considered anti-dilutive for the year ended
December 31, 2010.

14. HEDGING ACTIVITIES

Oil Price Hedging Activities

The Company seeks to reduce its exposure to unfavorable changes in oil prices, which are subject to
significant and often volatile fluctuation, by entering into forward sales contracts or fixed price swaps. These
contracts allow the Company to predict with greater certainty the effective oil prices to be received for hedged
production and benefit operating cash flows and earnings when market prices are less than the fixed prices
provided in the contracts. However, the Company will not benefit from market prices that are higher than the
fixed prices in the contracts for hedged production.

The Company accounts for its oil derivative instruments as cash flow hedges for accounting purposes under
FASB ASC 815 and related pronouncements. All derivative contracts are marked to market each quarter end and
are included in the accompanying consolidated balance sheets as derivative assets and liabilities.

At December 31, 2010, the fair value of derivative liabilities related to the fixed price swaps is as follows:

Short-term derivative instruments – liability . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

$4,720,000

At December 31, 2009, the fair value of derivative liabilities related to the forward sales contracts is as

follows:

Short-term derivative instruments – liability . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

$18,735,000

All forward sales contracts and fixed price swaps have been executed in connection with the Company’s oil

price hedging program. For forward sales contracts and fixed price swaps qualifying as cash flow hedges
pursuant to FASB ASC 815, the realized contract price is included in oil sales in the period for which the
underlying production was hedged.

For derivatives designated as cash flow hedges and meeting the effectiveness guidelines of FASB ASC 815,

changes in fair value are recognized in accumulated other comprehensive income until the hedged item is
recognized in earnings. Amounts reclassified out of accumulated other comprehensive income into earnings as a
component of oil and condensate sales for the years ended December 31, 2010 and 2009 are presented below.

(Reduction) addition to oil and condensate sales . . . . . . . . . . . . . . . . . . .

The Company expects to reclassify $4,720,000 out of accumulated other comprehensive income into
earnings as a component of oil and condensate sales during the year ended December 31, 2011 related to fixed
price swaps.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
DECEMBER 31, 2010, 2009 AND 2008
(Amounts rounded to nearest thousand)

Hedge effectiveness is measured at least quarterly based on the relative changes in fair value between the

derivative contract and the hedged item over time. Any change in fair value resulting from ineffectiveness is
recognized immediately in earnings. The Company did not recognize into earnings any amount related to hedge
effectiveness for the year ended December 31, 2010 related to the 2010 hedges as these hedges were deemed to
be perfectly effective. The Company did not recognize into earnings any amount related to hedge ineffectiveness
for the year ended December 31, 2010 related to the 2011 hedges, however, these hedges could be considered
ineffective in future periods.

During the fourth quarter of 2010, the Company entered into fixed price swap contracts for 2011 with the
purchaser of the Company’s WCBB oil and another financial institution. The Company will pay the counterparty
the excess of the oil market price over the fixed price and will receive the excess of the fixed price over the
market prices as defined in each contract. The Company’s fixed price swap contracts are tied to the commodity
prices on the New York Mercantile Exchange (“NYMEX”). The Company will receive the fixed price amount
stated in the contract and pay to its counterparty the current market price for oil as listed on the NYMEX West
Texas Index (“WTI”). However, due to the geographic location of the Company’s assets and the cost of
transporting oil to another market, the amount that the Company receives when it actually sells its oil differs
from the index price. At December 31, 2010, the Company had the following fixed price swaps in place:

In 2009, the Company was party to forward sales contracts for the sale of 3,000 barrels of WCBB

production per day at a weighted average daily price of $55.17 per barrel, before transportation costs and
differentials, for the period April 2009 to August 2009. The Company also was party to forward sales contracts
for the sale of 3,000 barrels of WCBB production per day at a weighted average daily price of $54.81 per barrel,
before transportation costs and differentials, for the period September 2009 to December 2009. For the period
January 2010 through February 2010, the Company was party to forward sales contracts for the sale of 3,000
barrels of WCBB production per day at a weighted average daily price of $54.81 per barrel, before transportation
costs and differentials. For the period March 2010 through December 2010, the Company was party to forward
sales contracts for the sale of 2,300 barrels of WCBB production per day at a weighted average daily price of
$58.24 per barrel, before transportation costs and differentials.

In the first quarter of 2009, the Company terminated forward sales contracts for 3,000 barrels per day of

March 2009 production for approximately $1.5 million and terminated forward sales contracts for 3,000 barrels
per day in the second quarter of 2009 for $476,000. For the year ended December 31, 2009, approximately $2.0
million related to such terminations is included in oil and condensate sales on the accompanying consolidated
statements of operations. There were no contracts in place which were accounted for as hedges at December 31,
2008.

The Company delivered approximately 45% of its 2010 production under forward sales contracts.

15. FAIR VALUE MEASUREMENTS

The Company adopted FASB ASC 820 for all financial assets and liabilities measured at fair value on a
recurring basis. The Company adopted FASB ASC 820 effective January 1, 2009 for all non-financial assets and
liabilities. FASB ASC 820 defines fair value as the price that would be received to sell an asset or paid to transfer

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
DECEMBER 31, 2010, 2009 AND 2008
(Amounts rounded to nearest thousand)

a liability (exit price) in an orderly transaction between market participants at the measurement date. The
statement establishes market or observable inputs as the preferred sources of values, followed by assumptions
based on hypothetical transactions in the absence of market inputs. The statement requires fair value
measurements be classified and disclosed in one of the following categories:

Level 1 – Quoted prices in active markets for identical assets and liabilities.

Level 2 – Quoted prices in active markets for similar assets and liabilities, quoted prices for identical or
similar instruments in markets that are not active and model-derived valuations whose inputs are observable
or whose significant value drivers are observable.

Level 3 – Significant inputs to the valuation model are unobservable.

Financial assets and liabilities are classified based on the lowest level of input that is significant to the fair

value measurement.

The estimated fair value of the Company’s fixed price swap contracts was based upon forward commodity

prices based on quoted market prices, adjusted for differentials.

The Company estimates asset retirement obligations pursuant to the provisions of FASB ASC Topic 410,

“Asset Retirement and Environmental Obligations” (“FASB ASC 410”). The initial measurement of asset
retirement obligations at fair value is calculated using discounted cash flow techniques and based on internal
estimates of future retirement costs associated with oil and gas properties. Given the unobservable nature of the
inputs, including plugging costs and reserve lives, the initial measurement of the asset retirement obligation
liability is deemed to use Level 3 inputs. See Note 4 for further discussion of the Company’s asset retirement
obligations. Asset retirement obligations incurred during the twelve months ended December 31, 2010 were
approximately $1,328,000.

16. OPERATING LEASES

In October 2006, the Company began leasing the Louisiana building that it owns to an unrelated party. The

cost of the building totaled approximately $217,000 and accumulated depreciation amounted to approximately

18. COMMITMENTS

Plugging and Abandonment Funds

In connection with the acquisition in 1997 of the remaining 50% interest in the WCBB properties, the

Company assumed the seller’s (Chevron) obligation to contribute approximately $18,000 per month through
March 2004, to a plugging and abandonment trust and the obligation to plug a minimum of 20 wells per year for
20 years commencing March 11, 1997. Chevron retained a security interest in production from these properties
until abandonment obligations to Chevron have been fulfilled. Beginning in 2009, the Company can access the
trust for use in plugging and abandonment charges associated with the property. As of December 31, 2010, the
plugging and abandonment trust totaled approximately $3,129,000. At December 31, 2010, the Company has
plugged 311 wells at WCBB since it began its plugging program in 1997, which management believes fulfills its
current minimum plugging obligation.

Texaco Global Settlement

Pursuant to the terms of a global settlement between Texaco and the State of Louisiana which includes the

State Lease No. 50 portion of Gulfport’s East Hackberry field, Gulfport was obligated to commence drilling a
well or other qualifying development operation on certain non-producing acreage in the field prior to March
1998. Because of prevailing market conditions during 1998, the Company believed it was commercially
impractical to shoot seismic or commence drilling operations on the subject property. As a result, Gulfport
agreed to surrender approximately 440 non-producing acres in this field to the State of Louisiana. At
December 31, 2010, Gulfport was in the process of releasing these properties to the State of Louisiana.

Contributions to 401(k) Plan

Gulfport sponsors a 401(k) and Profit Sharing plan under which eligible employees may contribute up to

15% of their total compensation through salary deferrals. Also under these plans, the Company will make a
contribution each calendar year on behalf of each employee equal to at least 3% of his or her salary, regardless of
the employee’s participation in salary deferrals. During the years ended December 31, 2010, 2009 and 2008,
Gulfport incurred $316,000, $279,000 and $651,000, respectively, in contributions expense related to this plan.

Employment Agreement

In May 1999, Gulfport entered into an employment agreement with its Chairman of the Board. The original

term of the agreement expired on May 31, 2004, but automatically renews for successive terms of one year
unless Gulfport or the Chairman elects otherwise. The employment agreement calls for an annual salary of
$200,000, subject to adjustment for cost of living increases.

The Company is party to an oral agreement with the Company’s Chief Executive Officer, with respect to his
compensation and benefits, pursuant to which he is entitled to an annual salary of $200,000 and, at the discretion
of the Company’s board of directors, an annual cash incentive bonus. The compensation committee of the Board
of Directors may make upward adjustments to this salary.

19. CONTINGENCIES

The Louisiana Department of Revenue (“LDR”) is disputing Gulfport’s severance tax payments to the State

of Louisiana from the sale of oil under fixed price contracts during the years 2005 to 2007. The LDR maintains

F-30

GULFPORT ENERGY CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)
DECEMBER 31, 2010, 2009 AND 2008
(Amounts rounded to nearest thousand)

that Gulfport paid approximately $1,800,000 less in severance taxes under fixed price terms than the severance
taxes Gulfport would have had to pay had it paid severance taxes on the oil at the contracted market rates only.
Gulfport has denied any liability to the LDR for underpayment of severance taxes and has maintained that it was
entitled to enter into the fixed price contracts with unrelated third parties and pay severance taxes based upon the
proceeds received under those contracts. Gulfport has maintained its right to contest any final assessment or suit
for collection if brought by the State. On April 20, 2009, the LDR filed a lawsuit in the 15th Judicial District
Court, Lafayette Parish, in Louisiana against Gulfport seeking $2,275,729 in severance taxes, plus interest and
court costs. Gulfport filed a response denying any liability to the LDR for underpayment of severance taxes and
is defending itself in the lawsuit.

In December 2010, the LDR filed two identical lawsuits against Gulfport in different venues to recover
allegedly underpaid severance taxes on crude oil for the period January 1, 2007 through December 31, 2010,
together with a claim for attorney's fees. The petitions do not make any specific claim for damages or unpaid
taxes. As with the first lawsuit filed by LDR in 2009, Gulfport denies all liability and will vigorously defend the
lawsuit. The cases are in the early stages, and Gulfport has not yet filed a response to the recent lawsuits.

Other Litigation

In November 2006, Cudd Pressure Control, Inc. (“Cudd”) filed a lawsuit against Gulfport, Great White
Pressure Control LLC (“Great White”) and six former Cudd employees in the 129th Judicial District Harris
County, Texas. The lawsuit was subsequently removed to the United States District Court for the Southern
District of Texas (Houston Division). The lawsuit alleged RICO violations and several other causes of action
relating to Great White’s employment of the former Cudd employees and sought unspecified monetary damages
and injunctive relief. On stipulation by the parties, the plaintiff’s RICO claim was dismissed without prejudice by
order of the court on February 14, 2007. Gulfport filed a motion for summary judgment on October 5, 2007. The
court entered a final interlocutory judgment in favor of all defendants, including Gulfport, on April 8, 2008. On
November 3, 2008, Cudd filed its appeal with the U.S. Court of Appeals for the Fifth Circuit. The Fifth Circuit
vacated the district court decision finding, among other things, that the district court should not have entered
summary judgment without first allowing more discovery. The case was remanded to the district court, and Cudd
filed a motion to remand the case to the original state court, which motion was granted. On February 3, 2010,
Cudd filed its second amended petition with the state court (a) alleging that Gulfport conspired with the other
defendants to misappropriate, and misappropriated, Cudd’s trade secrets and caused its employees to breach their
fiduciary duties, and (b) seeking unspecified monetary damages. On April 13, 2010, Gulfport’s motion to be
dismissed from the proceeding for lack of personal jurisdiction was denied. This state court proceeding is in its
initial stages. In 2011, the parties have continued with written discovery and production of documents. Cudd filed
a third amended petition seeking $26.5 million (based on a report prepared by its expert) plus disgorgement of $6
million in payments by Great White to the individual defendants and punitive damages. Gulfport denies these
claims with respect to itself.

On July 30, 2010, six individuals and one limited liability company sued 15 oil and gas companies in Cameron

Parish Louisiana for contamination across the surface of where the defendants operated in an action entitled Reeds
et al. v. BP American Production Company et al., 38th Judicial District. No. 10-18714. The plaintiffs’ original
petition for damages, which did not name Gulfport as a defendant, alleges that the plaintiffs’ property located in
Cameron Parish, Louisiana within the Hackberry oil field is contaminated as a result of historic oil and gas
exploration and production activities. Plaintiffs allege that the defendants, which in addition to BP America
Production Company include ExxonMobil Corporation, Shell Oil Company, ConocoPhillips Company, Sun Oil
Company and Schlumberger Technology Corporation, conducted, directed and participated in various oil and gas

F-31

exploration and production activities on their property which allegedly have contaminated or otherwise caused
damage to the property, and have sued the defendants for alleged breaches of oil, gas and mineral leases, as well as
for alleged negligence, trespass, failure to warn, strict liability, punitive damages, lease liability, contract liability,
unjust enrichment, restoration damages, assessment and response costs and stigma damages. On December 7, 2010,
Gulfport was served with a copy of the plaintiffs’ first supplemental and amending petition which added four
additional plaintiffs and six additional defendants, including Gulfport, bringing the total number of defendants to
21. It also increased the total acreage at issue in this litigation from 240 acres to approximately 1,700 acres. In
addition to the damages sought in the original petition, the plaintiffs now also seek: damages sufficient to cover the
cost of conducting a comprehensive environmental assessment of all present and yet unidentified pollution and
contamination of their property; the cost to restore the property to its pre-polluted original condition; damages for
mental anguish and annoyance, discomfort and inconvenience caused by the nuisance created by defendants; land
loss and subsidence damages and the cost of backfilling canals and other excavations; damages for loss of use of
land and lost profits and income; attorney fees and expenses and damages for evaluation and remediation of any
contamination that threatens groundwater. On January 21, 2011, Gulfport filed a pleading challenging the legal
sufficiency of the petitions and requesting that they either be dismissed or that plaintiffs be required to amend such
petitions. Gulfport’s motion is currently set to be heard on March 23, 2011.

Due to the current stages of the LDR, Cudd and Reed litigation, the outcome is uncertain and management

cannot determine the amount of loss, if any, that may result. Litigation is inherently uncertain. Adverse decisions
in one or more of the above matters could have a material adverse effect on the Company’s financial condition or
results of operations.

The Company has been named as a defendant on various other litigation matters. The ultimate resolution of
these matters is not expected to have a material adverse effect on the Company’s financial condition or results of
operations for the periods presented in the consolidated financial statements.

Concentration of Credit Risk

Gulfport operates in the oil and gas industry principally in the state of Louisiana with sales to refineries,
re-sellers such as pipeline companies, and local distribution companies. While certain of these customers are
affected by periodic downturns in the economy in general or in their specific segment of the oil and gas industry,
Gulfport believes that its level of credit-related losses due to such economic fluctuations has been immaterial and
will continue to be immaterial to the Company’s results of operations in the long term.

The Company maintains cash balances at several banks. Accounts at each institution are insured by the
Federal Deposit Insurance Corporation up to $250,000. At December 31, 2010, Gulfport held cash in excess of
insured limits in these banks totaling $1,986,000.

During the year ended December 31, 2010, Gulfport sold approximately 75% and 19% of its oil production

to Shell Trading Company (“Shell”) and WEG, respectively, and 50%, 32% and 10% of its natural gas
production to WEG, Chevron, and Hilcorp Energy Company (“Hilcorp”), respectively. During the year ended
December 31, 2009, Gulfport sold approximately 92% and 7% of its oil production to Shell and WEG,
respectively, 100% of its natural gas liquids production to WEG, and 45%, 38%, and 16% of its natural gas
production to WEG, Chevron, and Hilcorp, respectively. During the year ended December 31, 2008, Gulfport
sold approximately 87% and 11% of its oil production to Shell and WEG, respectively, 100% of its natural gas
liquids production to WEG, and 60%, 22%, and 16% of its natural gas production to Chevron, WEG, and
Hilcorp, respectively.

Forward Sales Contracts

The Company was party to forward sales contracts for the sale of 3,500 barrels of production per day for the

months of January 2008 through May 2008 at a weighted average daily price of $70.29 per barrel before
transportation costs. For June 2008, the Company had agreements to sell 3,500 barrels of production per day at a
weighted average daily price of $71.69 per barrel before transportation costs. For the month of July 2008, the
Company had agreements to sell 3,500 barrels of production per day at a weighted average daily price of $85.89
per barrel before transportation costs. For August 2008, Gulfport had agreements to sell 3,500 barrels of
production per day at a weighted average daily price of $86.81 per barrel before transportation costs. For the
periods September 2008 through December 2008, the Company entered into forward sales contracts for the sale
of 3,500 barrels of production per day at a weighted average daily price of $86.60 per barrel before transportation
costs. For the period of January 2009 through December 2009, the Company entered into agreements to sell
3,000 barrels of production per day at a weighted average daily price of $89.06 per barrel before transportation
costs. These contracts were originally designated as normal sales of production under FASB ASC 815, based on
the Company’s intent to physically deliver the production quantities under the contract terms, and exempted from
the provisions of FASB ASC 815.

In December 2008, the Company terminated the 2009 forward sales contracts in exchange for $39.0 million

cash, which is included in other (income) expense on the accompanying consolidated statements of operations.
As a result of this cash settlement, beginning in 2009, the Company is required to account for similar contracts
under the provisions of FASB ASC 815 until a reasonable period passes and the Company redevelops a past
history of physical delivery under fixed price contracts without net cash settlement. See Note 14 for further
discussion of the Company’s 2009 and 2010 forward sales contracts.

20. LITIGATION TRUST ENTITY

Pursuant to the Company’s 1997 plan of reorganization, all of Gulfport’s possible causes of action against
third parties (with the exception of certain litigation related to recovery of marine and rig equipment assets and
claims against Tri-Deck), existing as of the effective date of that plan, were transferred into a “Litigation Trust”
controlled by an independent party for the benefit of most of the Company’s existing unsecured creditors. The
litigation related to recovery of marine and rig equipment and the Tri-Deck claims were subsequently transferred
to the Litigation Trust as described below.

The Litigation Trust was funded by a $3,000,000 cash payment from the Company, which was made on the

effective date of reorganization. Gulfport owns a 12% interest in the Litigation Trust with the other 88% being
owned by the former general unsecured creditors of Gulfport. For financial statement reporting purposes,
Gulfport has not recognized the potential value of recoveries which may ultimately be obtained, if any, as a result
of the actions of the Litigation Trust, treating the entire $3,000,000 payment as a reorganization cost at the time
of Gulfport’s reorganization.

On January 20, 1998, Gulfport and the Litigation Trust entered into a Clarification Agreement whereby the

rights to pursue various claims reserved by Gulfport under the plan of reorganization were assigned to the
Litigation Trust. In connection with this agreement, the Litigation Trust agreed to reimburse the Company
$100,000 for legal fees Gulfport had incurred in connection with these claims. As additional consideration for the
contribution of this claim to the Litigation Trust, Gulfport is entitled to 20% to 80% of the net proceeds from
these claims.

Results of Operations for Producing Activities

The following schedule sets forth the revenues and expenses related to the production and sale of oil and

gas. The income tax expense is calculated by applying the current statutory tax rates to the revenues after
deducting costs, which include depreciation, depletion and amortization allowances, after giving effect to the
permanent differences. The results of operations exclude general office overhead and interest expense
attributable to oil and gas production.

Oil and Gas Reserves (Unaudited)

The following table presents estimated volumes of proved developed and undeveloped oil and gas reserves

as of December 31, 2010, 2009 and 2008 and changes in proved reserves during the last three years. The 2010
and 2009 reserve reports use an average price equal to the unweighted arithmetic average of hydrocarbon prices
received on a field-by-field basis on the first day of each month within the 12-month period ended December 31,
2010 and 2009, in accordance with revised guidelines of the SEC applicable to reserves estimates as of year-end
2009. Estimates of reserves as of year-end 2008 were prepared using constant prices and costs in accordance with
previous guidelines of the SEC based on hydrocarbon prices received on a field-by-field basis as of
December 31, 2008. Volumes for oil are stated in thousands of barrels (MBbls) and volumes for gas are stated in
millions of cubic feet (MMcf). The prices used for the 2010 reserve report are $76.16 per barrel and $4.38 per
MMbtu, adjusted by lease for transportation fees and regional price differentials, and for oil and gas reserves,
respectively. The prices used at December 31, 2009 and 2008 for reserve report purposes are $57.90 per barrel
and $3.87 per MMbtu and $41.00 per barrel and $5.71 per MMbtu, respectively.

Gulfport emphasizes that the volumes of reserves shown below are estimates which, by their nature, are

subject to revision. The estimates are made using all available geological and reservoir data, as well as
production performance data. These estimates are reviewed annually and revised, either upward or downward, as
warranted by additional performance data.

The Company experienced downward reserve revisions in estimated proved reserves in 2010. These
downward revisions were primarily the result of the application of the five-year schedule for the development of
proved undeveloped reserves required by the SEC’s “Modernization of Oil and Gas Reporting” Final Rule,
which resulted in the elimination of proved undeveloped reserves that remained undeveloped beyond such five-
year schedule. The Company experienced downward reserve revisions in estimated proved reserves in 2009.
These downward revisions were primarily the result of application of the five-year schedule for the development
of proved undeveloped reserves required by the SEC’s “Modernization of Oil and Gas Reporting” Final Rule.
The Company experienced downward reserve revisions in estimated proved reserves in 2008. These downward
revisions were primarily a result of year end commodity prices utilized for the reserve estimate decreasing from
$92.50 per barrel and $6.80 per MMbtu at December 31, 2007 to $41.00 per barrel and $5.71 per MMbtu at
December 31, 2008.

In February 2011, the Company entered into an agreement to acquire certain leasehold interests located in

the Utica Shale in Ohio. The agreement also grants the Company an exclusive right of first refusal for a period of
six months on certain additional tracts leased by the seller. Windsor, an affiliate of the Company, has agreed to
participate with the Company on a 50/50 basis in the acquisition of all leases described above. Gulfport will be
the operator on this acreage in the Utica Shale. The purchase price for the Company’s 50% interest in the initial
acreage is approximately $31,625,000, subject to certain closing adjustments. This transaction is expected to
close in mid-May 2011.
