Terms used to describe quantities of oil and natural gas and marketing

•

•

•

•

•

•

•

•

•

•

•

•

•

•

  Bbl — One stock tank barrel, or 42 U.S. gallons liquid volume, of crude oil or other liquid hydrocarbons.

  Bcf — One billion cubic feet of natural gas.

  Bcfe — One billion cubic feet of natural gas equivalent.

  BOE — One barrel of oil equivalent, converting natural gas to oil at the ratio of 6 Mcf of natural gas to 1 Bbl of oil.

  BTU — British Thermal Unit.

  Condensate — An oil-like, liquid hydrocarbon which is produced in association with natural gas production that condenses from natural gas as it
is  produced  and  delivered  into  a  separator  or  similar  equipment  prior  to  the  delivery  of  such  natural  gas  to  the  natural  gas  gathering  pipeline
system.

  MBbl — One thousand barrels of crude oil or other liquid hydrocarbons.

  Mcf — One thousand cubic feet of natural gas.

  Mcfe — One thousand cubic feet of natural gas equivalent, converting oil or condensate to natural gas at the ratio of 1 Bbl of oil or condensate to
6 Mcf of natural gas. This conversion ratio, which is typically used in the oil and gas industry, represents the approximate energy equivalent of a
barrel of oil or condensate to an Mcf of natural gas. The sales price of one barrel of oil or condensate has been much higher than the sales price of
six Mcf of natural gas over the last several years, so a six to one conversion ratio does not represent the economic equivalency of six Mcf of
natural gas to one barrel of oil or condensate.

  MMBbl — One million barrels of crude oil or other liquid hydrocarbons.

  MMcf — One million cubic feet of natural gas.

  MBOE — One thousand BOE.

  MMBOE — One million BOE.

  MMBTU — One million British Thermal Units.

Terms used to describe the Company's interests in wells and acreage

•

•

•

  Gross oil and natural gas wells or acres — The Company's gross wells or gross acres represent the total number of wells or acres in which the

Company owns a working interest.

  Net oil and natural gas wells or acres — Determined by multiplying "gross" oil and natural gas wells or acres by the working interest that the

Company owns in such wells or acres represented by the underlying properties.

  Prospect  —  A  location  where  hydrocarbons  such  as  oil  and  gas  are  believed  to  be  present  in  quantities  which  are  economically  feasible  to

produce.

Terms used to assign a present value to the Company's reserves

•

  Standardized measure of discounted future net cash flows, after income taxes — The present value, discounted at 10%, of the after tax future
net cash flows attributable to estimated net proved reserves. The Company calculates this amount by assuming that it will sell the oil and natural
gas production attributable to the proved reserves estimated in its independent engineer's reserve report for the oil and

Table of Contents

natural  gas  spot  prices  based  on  the  average  price  during  the  12-month  period  before  the  ending  date  of  the  period  covered  by  the  report
determined as an unweighted, arithmetic average of the first-day-of-the-month price for each month within such period, adjusted for quality and
transportation. The Company also assumes that the cost to produce the reserves will remain constant at the costs prevailing on the date of the
report. The assumed costs are subtracted from the assumed revenues resulting in a stream of future net cash flows. Estimated future income taxes,
using rates in effect on the date of the report, are deducted from the net cash flow stream. The after-tax cash flows are discounted at 10% to result
in the standardized measure of the Company's proved reserves.

•

  Standardized measure of discounted future net cash flows before income taxes — The discounted present value of proved reserves is identical
to the standardized measure described above, except that estimated future income taxes are not deducted in calculating future net cash flows. The
Company  discloses  the  discounted  present  value  without  deducting  estimated  income  taxes  to  provide  what  it  believes  is  a  better  basis  for
comparison of its reserves to the producers who may have different income tax rates.

Terms used to classify the Company's reserve quantities

The Securities and Exchange Commission ("SEC") definition of proved oil and natural gas reserves, per Regulation S-X, is as follows:

Economically producible — A resource that generates revenue that exceeds (or is reasonably expected to exceed) costs of the operation.

Estimated ultimate recovery ("EUR") — The sum of reserves remaining as of a given date and cumulative production as of that date.

Proved oil and gas reserves — Proved oil and natural gas reserves are those quantities of oil and gas, which, by analysis of available geoscience
and engineering data, can be estimated with reasonable certainty to be economically producible — from a given date forward from known reservoirs
and under existing economic conditions, operating methods, and government regulation — before the time at which contracts providing the right to
operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the
estimation.

The project to extract the hydrocarbons must have commenced or the operator must be reasonably certain that it will commence the project within a

reasonable time.

The area of the reservoir considered as proved includes all of the following:

a. The area identified by drilling and limited fluid contacts, if any,

b. Adjacent undrilled portions of the reservoir that can, with reasonable certainty, be judged to be continuous with it and to contain economically

producible oil or gas on the basis of available geoscience and engineering data.

In the absence of data on fluid contacts, proved quantities in a reservoir are limited by the lowest known hydrocarbons as seen in a well penetration

unless geoscience, engineering, or performance data and reliable technology establish a lower contact with reasonable certainty.

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

4

 
 
 
 
 
Table of Contents

Reserves  that  can  be  produced  economically  through  application  of  improved  recovery  techniques  (including,  but  not  limited  to,  fluid  injection)  are

included in the proved classification when both of the following occur:

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

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

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

Proved developed oil and gas reserves — Proved oil and gas reserves that can be expected to be recovered:

a.  Through  existing  wells  with  existing  equipment  and  operating  methods  or  in  which  the  cost  of  the  required  equipment  is  relatively  minor

compared with the cost of a new well.

b.  Through  installed  extraction  equipment  and  infrastructure  operational  at  the  time  of  the  reserves  estimate  if  the  extraction  is  by  means  not

involving a well.

Proved undeveloped oil and gas reserves — Proved oil and gas reserves that are expected to be recovered from new wells on undrilled acreage, or from
existing wells where a relatively major expenditure is required for recompletion. Reserves on undrilled acreage shall be limited to those directly offsetting
development spacing areas that are reasonably certain of production when drilled, unless evidence using reliable technology exists that establishes reasonable
certainty of economic producibility at greater distances.

Undrilled locations can be classified as having undeveloped reserves only if a development plan has been adopted indicating that they are scheduled to

be drilled within five years, unless the specific circumstances justify a longer time.

Under no circumstances are estimates for proved undeveloped reserves attributable to any acreage for which an application of fluid injection or other
improved recovery technique is contemplated, unless such techniques have been proved effective by actual projects in the same reservoir or an analogous
reservoir, or by other evidence using reliable technology establishing reasonable certainty.

Reasonable certainty — If deterministic methods are used, a high degree of confidence that the quantities will be recovered. If probabilistic methods
are used, at least a 90 percent probability that the quantities actually recovered will equal or exceed the estimate. A high degree of confidence exists if the
quantity is much more likely to be achieved than not, and, as changes due to increased availability of geoscience (geological, geophysical, and geochemical),
engineering, and economic data are made to estimated ultimate recovery (EUR) with time, reasonably certain EUR is much more likely to increase or remain
constant than to decrease.

Reliable  technology  —  A  grouping  of  one  or  more  technologies  (including  computational  methods)  that  has  been  field  tested  and  demonstrated  to

provide reasonably certain results with consistency and repeatability in the formation being evaluated or in an analogous formation.

Resources  —  Quantities  of  oil  and  gas  estimated  to  exist  in  naturally  occurring  accumulations.  A  portion  of  the  resources  may  be  estimated  to  be

recoverable, and another portion may be considered to be unrecoverable. Resources include both discovered and undiscovered accumulations.

Terms used to describe the legal ownership of the Company's oil and natural gas properties

•

•

  Revenue interest — The amount of the interest owned in the proceeds derived from a producing well less all royalty interests.

  Working interest — A real property interest entitling the owner to receive a specified percentage of the proceeds of the sale of oil and natural gas
production or a percentage of the production, but requiring the owner of the working interest to bear the cost to explore for, develop and produce
such oil and natural gas. A working interest owner who owns a portion of the working interest may participate either as operator or by voting his
percentage  interest  to  approve  or  disapprove  the  appointment  of  an  operator  and  drilling  and  other  major  activities  in  connection  with  the
development and operation of a property.

Terms used to describe seismic operations

•

•

•

  Seismic data — Oil and natural gas companies use seismic data as their principal source of information to locate oil and natural gas deposits,
both to aid in exploration for new deposits and to manage or enhance production from known reservoirs. To gather seismic data, an energy source
is used to send sound waves into the subsurface strata. These waves are reflected back to the surface by underground formations, where they are
detected by geophones which digitize and record the reflected waves. Computers are then used to process the raw data to develop an image of
underground formations.

  2-D seismic data — 2-D seismic survey data has been the standard acquisition technique used to image geologic formations over a broad area. 2-
D seismic data is collected by a single line of energy sources which reflect seismic waves to a single line of geophones. When processed, 2-D
seismic data produces an image of a single vertical plane of sub-surface data.

  3-D seismic data — 3-D seismic data is collected using a grid of energy sources, which are generally spread over several miles. A 3-D survey
produces a three dimensional image of the subsurface geology by collecting seismic data along parallel lines and creating a cube of information
that  can  be  divided  into  various  planes,  thus  improving  visualization.  Consequently,  3-D  seismic  data  is  generally  considered  a  more  reliable
indicator of potential oil and natural gas reservoirs in the area evaluated.

Other Terms

•

•

•

  All-in costs — The sum of costs per Mcfe relating to lease operating expenses, severance taxes, gathering costs, transportation charges, depletion,

depreciation and amortization, interest expense and general and administrative expenses.

  Reserve replacement ratio — The sum of the estimated net proved reserves added through discoveries, extensions, infill drilling and acquisitions
(which may include or exclude reserve revisions of previous estimates) for a specified period of time divided by production for that same period
of time.

  Finding  and  development  costs  —  Finding  and  development  costs,  including  revisions,  are  calculated  by  dividing  the  sum  of  property
acquisition costs, exploration costs and development costs for the year, by the total of reserve extensions, discoveries, purchases and all revisions
for the year.

General

PART I

Ultra  Petroleum  Corp.  ("Ultra"  or  the  "Company")  is  an  independent  oil  and  gas  company  engaged  in  the  development,  production,  operation,
exploration and acquisition of oil and natural gas properties. The Company was incorporated on November 14, 1979, under the laws of the Province of British
Columbia,  Canada.  Ultra  remains  a  Canadian  company,  but  since  March  2000,  has  operated  under  the  laws  of  The  Yukon  Territory,  Canada  pursuant  to
Section  190  of  the  Business  Corporations  Act  (Yukon  Territory).  The  Company's  operations  are  primarily  located  in  the  Green  River  Basin  of  southwest
Wyoming and the north-central Pennsylvania area of the Appalachian Basin. In addition, the Company has recently acquired acreage in eastern Colorado's
Denver Julesburg Basin.

Oil and Gas Properties Overview

Ultra's current operations in southwest Wyoming are focused on developing its long-life natural gas reserves in a tight gas sand trend located in the
Green River Basin with targets in the sands of the upper Cretaceous Lance Pool in the Pinedale and Jonah fields. The Lance Pool, as administered by the
Wyoming  Oil  and  Gas  Conservation  Commission  ("WOGCC"),  includes  sands  of  both  the  Lance  (found  at  subsurface  depths  of  approximately  8,000  to
12,000 feet) and Mesaverde (found at subsurface depths of approximately 12,000 to 14,000 feet) in the Pinedale and Jonah fields area of Sublette County,
Wyoming. As of December 31, 2011, Ultra owned interests in approximately 93,000 gross (53,000 net) acres in Wyoming covering approximately 190 square
miles.

Ultra's current operations in north-central Pennsylvania are focused on assessing, exploring and developing its position in the Marcellus Shale and other

horizons. At December 31, 2011, the Company owned interests in approximately 499,000 gross (258,000 net) acres in Pennsylvania.

In eastern Colorado, the Company acquired 149,000 gross (130,000 net) acres during the year ended December 31, 2011. Ultra's operations in this area

will be focused on assessing, exploring and developing its position targeting the Niobrara formation in the Denver Julesburg Basin.

Business Strategy

Ultra's mission is to profitably grow an upstream oil and gas company for the long-term benefit of its shareholders. Ultra's strategy includes building a
robust portfolio of high return investment opportunities, maintaining a disciplined approach to capital investment, maximizing earnings and cash flows by
controlling costs and maintaining financial flexibility.

High Return Portfolio.    Ultra seeks to maintain a portfolio of properties that provide long-term, profitable growth through development in areas that

support sustainable, lower-risk, repeatable, high return drilling

7

 
 
Table of Contents

projects. The Company continually evaluates opportunities for the acquisition, exploration and development of additional oil and natural gas properties that
afford risk-adjusted returns in excess of or equal to its current set of investment alternatives.

Disciplined  Capital  Investment.        The  Company's  business  strategy  involves  the  regular  review  of  its  investment  opportunities  in  order  to  optimize
return to its shareholders. Over the past twelve years, Ultra has consistently delivered meaningful reserve and production growth. In 2011, oil and natural gas
production increased 15% over 2010 levels and estimated proved reserves increased 13% to 5.0 Tcfe from 4.4 Tcfe with return on capital employed of 13%
and return on equity of 31%.

Low Cost Producer.    Ultra strives to maintain one of the lowest cost structures in the industry in terms of both adding and producing oil and natural
gas  reserves.  The  Company  continues  to  focus  on  improving  its  drilling  and  production  results  through  the  use  of  advanced  technologies  and  detailed
technical analysis of its properties. For the year ended 2011, the Company's all-in costs were $2.88 per Mcfe with finding and development costs of $1.60 per
Mcfe.

Financial Flexibility.    Preserving financial flexibility and a strong balance sheet are also strategic to Ultra's business philosophy. At December 31,
2011, the Company had cash on hand of $11.3 million and outstanding debt was $1.9 billion. Consistent with this strategy and in anticipation of the upcoming
maturity  of  the  Company's  (through  its  subsidiary,  Ultra  Resources)  senior,  unsecured  revolving  2007  Credit  Agreement  ("2007  Credit  Agreement"),  the
Company replaced the 2007 Credit Agreement in its entirety with a new senior, unsecured revolving credit facility and repaid all amounts under the 2007
Credit  Agreement  with  proceeds  of  loans  drawn  under  the  new  facility  during  the  fourth  quarter  of  2011.  The  Company's  average  debt  maturity  profile  is
approximately eight years while the Company's weighted average cost of debt is approximately 4.9%.

Exploration and Production

Green River Basin, Wyoming

During 2011, the Company participated in the drilling of 235 wells in Wyoming and continued to improve its drilling and completion efficiency on its
operated  wells  as  measured  by  spud  to  total  depth.  During  2011,  the  Company  averaged  12  days  to  drill  a  well,  as  measured  by  spud  to  total  depth.  This
compares to an average of 14 days to drill during 2010, a 14% reduction. Similarly, Ultra reached total depth in 15 days or less on 95% of all operated wells
during 2011 as compared to 76% of all operated wells during the prior year. Total days per well, measured by rig-release to rig-release, decreased 12% to 15
days in 2011 compared to 17 days during 2010.

During 2012, the Company plans to continue its ongoing development program of its acreage position in the tight gas sand trend in the Green River
Basin  in  southwest  Wyoming.  The  Company  expects  that  wells  drilled  during  2012  in  the  Pinedale  or  Jonah  fields  will  target  the  sands  of  the  upper
Cretaceous Lance Pool.

Additionally, the Company plans to continue its assessment of increased density drilling to more efficiently recover the oil and gas resources present in
the area. During 2011, based on results of its 5-acre wells drilled in 2010, Ultra sought and obtained approval from the WOGCC to file for development of its
acreage in Pinedale at a well density of 32 wells per 160-acre government quarter section (5-acre equivalent). Current spacing in the Jonah field is eight wells
per 80-acre drilling and spacing unit (10-acre spacing) with several pilots testing spacing at 16 wells per 80-acre drilling and spacing unit (5-acre spacing).

All of the Company's drilling activity is conducted utilizing its extensive integrated geological and geophysical data set. This data set is being utilized to
map the potentially productive intervals, to refine areas of drilling focus, to identify areas for future extension of the Lance fairway and to identify deeper
objectives which may warrant drilling.

Pennsylvania

Ultra continued the assessment of its acreage in Pennsylvania during 2011. During the year, the Company participated in the drilling of 161 horizontal

wells and continued to evaluate the 3D seismic data on its properties.

The Company is actively leveraging its Pinedale experience by translating its Wyoming directional drilling, completion and production knowledge to
the Marcellus. During 2012, the Company plans to continue executing its exploration and development activities in the Middle Devonian Marcellus Shale
play on its acreage position in Pennsylvania. Ultra's current activities are located in Potter, Tioga, Clinton, Centre and Lycoming counties. Activities include
lease acquisition, 3-D seismic, drilling, completion, infrastructure construction and production operations.

Colorado

During 2011, the Company acquired an acreage position in eastern Colorado's Denver Julesburg Basin with plans to explore and develop the Niobrara
formation. During 2012, the Company plans to acquire additional acreage and drill and complete several exploration wells to evaluate the potential for oil
production from its acreage.

Marketing and Pricing

Overview

Ultra derives its revenues principally from the sale of its natural gas and associated condensate production from wells operated by the Company and
others in the Green River Basin in southwest Wyoming. An increasing portion of the Company's revenues is associated with gas sales from wells operated by
the  Company  and  others  in  the  Appalachian  Basin  in  Pennsylvania.  Historically,  the  Company's  revenues  have  been  determined,  to  a  large  degree,  by
prevailing  natural  gas  prices  for  production  situated  in  the  Rocky  Mountain  region  of  the  United  States,  specifically,  southwest  Wyoming.  With  the
completion  of  the  Rockies  Express  Pipeline  ("REX")  in  2009,  a  substantial  portion  of  the  Company's  revenues  are  now  determined  by  natural  gas  market
prices in the Midwestern and Eastern regions of the United States. Energy commodity prices in general, and natural gas prices in particular, have been highly
volatile, and such volatility is expected to continue in the future.

Natural Gas Marketing

Ultra  currently  sells  all  of  its  natural  gas  production  to  a  diverse  group  of  third-party,  non-affiliated  entities  in  a  portfolio  of  transactions  of  various
durations  and  prices  (daily,  monthly  and  longer  term).  Historically,  the  Company's  customers  were  predominately  located  in  the  western  United  States
— primarily California and the Pacific Northwest, as well as the Front Range area of Colorado and in Utah. With the REX pipeline now operational into
Ohio,  and  with  the  addition  of  new  gas  production  in  Pennsylvania,  the  Company's  customer  base  has  expanded  to  include  a  significant  number  of  new
customers situated in the Midwestern and Eastern regions of the United States. The sale of the Company's natural gas is "as produced". As such, the Company
does not maintain any significant inventories or imbalances of natural gas.

Midstream services.    For its natural gas production in Wyoming, the Company has entered into various gathering and processing agreements with
several  midstream  service  providers  that  gather,  compress  and  process  natural  gas  owned  or  controlled  by  the  Company  from  its  producing  wells  in  the
Pinedale Anticline and Jonah fields. Under these agreements, the midstream service providers have routinely expanded their facilities' capacities in southwest
Wyoming to accommodate growing volumes from wells in which the Company owns an interest. Such expansions are continuing and the Company believes
that the capacity of the midstream infrastructure related to its production will continue to be adequate to allow it to sell essentially all of its available natural
gas production from Wyoming.

During December 2011, a fire occurred at the Jonah Gas Gathering system's Falcon Compressor station in Sublette County, Wyoming, which caused

damage to the compression and disrupted production from the

9

 
 
Table of Contents

Pinedale field from December 6, 2011 until December 31, 2011. The owner and operator of the Jonah Gas Gathering system was able to re-provision some of
its existing and surplus pipeline and compression facilities to replace the capacity at the Falcon station that was lost to the fire and was able to restore its
capacity to receive and compress the Company's gas to "pre-fire" levels by the end of December 2011. Plans are currently being developed for specific actions
to permanently replace the compression capacity lost during the fire.

In  Pennsylvania,  the  Company  and  its  partners  are  constructing  gas  gathering  pipelines  and  facilities,  compression  facilities  and  pipeline  delivery
stations  to  gather  production  from  its  newly  completed  natural  gas  wells.  Construction  on  these  facilities  is  expected  to  continue  throughout  2012,  so  the
Company  can  continue  to  manage  its  midstream  capacity  to  coincide  with  increased  capacity  requirements  from  its  drilling  activities.  These  facilities  are
gathering systems and related infrastructure, and their construction is expected to continue, to some extent, until the Company's properties in Pennsylvania are
fully  developed.  To  date,  none  of  the  Company's  natural  gas  production  in  Pennsylvania  has  required  processing,  treating  or  blending  in  order  to  remove
natural gas liquids or other impurities and it is anticipated that treating facilities of this type will not be required in the future to accommodate the Company's
production.

Pipeline infrastructure.    The Company has taken actions to facilitate expansion of the pipeline infrastructure available to move its natural gas supplies
across the country, to provide sufficient capacity to transport its natural gas production and to provide for reasonable prices for its natural gas in the future.
Such actions include becoming an anchor shipper on REX, which begins at the Opal Processing Plant in southwest Wyoming and traverses Wyoming and
several other states to an ultimate terminus in eastern Ohio. In addition, during 2011, two new pipeline projects, plus expansion of an existing pipeline, all
originating in Wyoming and designed to transport natural gas to markets not previously accessible to Wyoming producers, were placed into service, further
increasing pipeline takeaway capacity from Wyoming. The Ruby Pipeline began deliveries of gas to Northern California markets in July 2011. The Bison
Pipeline  commenced  delivery  service  in  January  2011.  The  Kern  River  Pipeline  APEX  expansion,  serving  markets  in  and  near  Las  Vegas,  Nevada,  was
placed into service in October 2011. These three pipeline projects have added aggregate export pipeline capacity for Rockies/Wyoming gas of approximately
2.1 Bcf per day, a more than 20% increase over previous levels. The Company evaluated and declined the opportunity to commit to hold firm transportation
rights on these three new pipeline projects. The new pipeline projects have afforded the Company the benefit of improved market access as well as tightening
of the Rockies basis differential, as described below.

Basis differentials.    The market price for natural gas in the Rockies generally, and in southwest Wyoming specifically, is influenced by a number of
regional and national factors, all of which are somewhat unpredictable and are beyond the Company's ability to control. These factors include, among others,
weather,  natural  gas  supplies,  natural  gas  demand,  inventory  levels  in  natural  gas  storage  fields,  and  natural  gas  pipeline  capacity  to  export  gas  from  the
Rockies.

The Rocky Mountain region is a net exporter of natural gas because local natural gas production exceeds local demand, especially during non-winter
months. As a result, natural gas production in southwest Wyoming has historically sold at a discount relative to other U.S. natural gas production sources or
market areas. These regional pricing differentials, or discounts, are typically referred to as "basis" or "basis differentials" and are reflective, to some extent, of
the costs associated with transporting the Company's gas to markets in other regions or states. These differentials are also reflective of the general relative
abundance of, or lack of, export pipeline capacity to move gas out of the Rockies. The Inside FERC First of Month Index for Northwest Pipeline — Rocky
Mountains basis was generally wide since 2006 but narrowed during the latter portion of 2009 and has continued to narrow during 2011, primarily as a result
of  the  completion  of  the  REX  pipeline  into  Ohio,  as  well  as  additional  export  capacity  out  of  the  Rocky  Mountain  region  in  general.  (See  Pipeline
Infrastructure above).

The  table  below  provides  a  historical  and  future  perspective  on  average  annual  basis  differentials  for  Wyoming  natural  gas  (NW  Rockies)  and

historically premium markets in the Northeast (Dominion South). The

basis differential is expressed as a percentage of the Henry Hub price as reported by Platt's M2M (Mark to Market) Report on December 31, 2011.

The Company, from time to time and in the regular course of its business, hedges a portion of its natural gas production primarily through the use of
financial swaps with creditworthy financial counterparties (See Note 13), or through the use of fixed price, forward sales of physical gas. The Company may
elect to hedge additional portions of its forecasted natural gas production in the future, in much the same manner as it has done previously.

In response to the lower price environment resulting from the supply/demand imbalance during 2011, the Company continued to hedge a portion of its
exposure to volatile natural gas prices by entering into forward swaps for 2011 through 2012. This strategy of hedging will result in greater price certainty for
the  Company's  production  and  helps  protect  the  Company's  capital  investment  program  for  those  years.  For  a  more  detailed  description  of  the  Company's
hedging activities, see Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

The Company's hedging policy limits the amounts of resources hedged to not more than 50% of its forecast production without Board approval. As of
January  1,  2009,  2010  and  2011,  the  quantities  that  the  Company  hedged  for  the  succeeding  twelve  month  periods  represented  53%,  46%  and  67%,
respectively,  of  the  Company's  forecasted  production  for  such  periods.  During  2009  and  2011,  Ultra's  board  approved  hedges  of  greater  than  50%  of  the
Company's forecast production for each respective period.

Oil Marketing

The  Company  markets  its  Wyoming  condensate  to  various  purchasers,  which  are  primarily  refiners  in  the  Salt  Lake  City,  Utah  area.  The  pricing
realized from the sale of the Company's condensate production was more volatile during 2011 than in 2010, as a result of convergence of geopolitical factors,
burgeoning  domestic  oil  production  growth  and  resulting,  historically  wide  differential  (discount)  between  European  and  U.S.  oil  futures  prices.  The
Company's condensate realized pricing is typically based on New York Mercantile Exchange crude futures daily settlement prices, less a negotiated location/
transportation discount or differential. All of the Company's condensate sales are denominated in U.S. dollars per barrel and are paid for on a monthly basis.
The  Company  routinely  maintains  only  operating  inventories  of  condensate  production  and  sells  its  product  on  an  "as  produced"  basis.  A  portion  of  the
Company's condensate sales are done by its operating partners in the Pinedale field.

Historically, the Company's condensate production was gathered from its Wyoming well locations by tanker trucks and then shipped to other locations
for injection into crude oil pipelines or other facilities. Commencing in 2010, the Company began gathering its operated condensate production in its liquids
gathering system, which is designed to gather condensate from various leases and wells operated by the Company as contemplated under the Supplemental
Environment  Impact  Statement  ("SEIS")  and  Record  of  Decision  ("ROD")  as  discussed  below  in  Environmental  Matters.  The  condensate  is  transported
through the liquids gathering system to four central gathering facilities in the Pinedale field where it can be loaded into trucks or delivered into pipelines for
delivery to the Company's customers. At the end of 2011, more than 80% of the Company's operated condensate production in Wyoming was delivered from
the Company's liquids gathering system directly into a pipeline, further reducing truck traffic and improving flow assurance as well as realized pricing.

Significant Counterparties

A significant counterparty is defined as one that individually accounts for 10% or more of the Company's total revenues during the year. In 2011, the

Company had no single counterparty that represented 10% or more of the Company's total revenues.

The  Company  maintains  credit  policies  intended  to  mitigate  the  risk  of  uncollectible  accounts  receivable  related  to  the  sale  of  natural  gas  and
condensate as well as commodity derivatives. A more complete description of the Company's credit policies are described in Note 13. The Company did not
have any outstanding, uncollectible accounts for its natural gas and oil sales at December 31, 2011.

Environmental Matters

The U.S. Bureau of Land Management ("BLM") initiates preparation of an Environmental Impact Statement ("EIS") relating to potential natural gas
development on federal lands in the Pinedale Anticline area in the Green River Basin of Wyoming. An EIS is required under the National Environmental
Policy  Act  ("NEPA")  for  major  federal  actions  significantly  affecting  the  quality  of  the  human  environment  and  entails  consideration  of  environmental
consequences  of  a  proposed  action  and  its  alternatives.  Although  the  Company  co-owns  leases  on  state  and  privately  owned  lands  in  the  vicinity  of  the
Pinedale Anticline that do not fall under the federal jurisdiction of the BLM and are not subject to the EIS requirement, the area north of the Jonah field,
including the Pinedale Anticline, which the EIS addresses, is where most of the Company's exploration and development is taking place. The BLM issues a
ROD with respect to a final EIS, which allows for surface disturbances for drilling and production activities within the area covered by the EIS, but does not
authorize  the  drilling  of  particular  wells.  Ultra,  therefore,  must  submit  applications  to  the  BLM's  Pinedale  field  manager  for  permits  and  other  required
authorizations, such as rights-of-way for each specific well or particular pipeline location. In making its determination on whether to approve specific drilling
or development activities, the BLM applies the requirements of the ROD.

The  ROD  imposes  limits  on  drilling  and  completion  activity  and  proposes  mitigation  guidelines,  standard  practices  for  industry  activities  and  best
management practices for sensitive areas. The Company cannot predict if or how these adjustments may affect permitting, development and compliance under
the  ROD.  The  BLM's  field  manager  may  also  impose  additional  limitations  and  mitigation  measures  as  are  deemed  reasonably  necessary  to  mitigate  the
impact of drilling and production operations in the area.

To date, the Company has expended significant resources in order to satisfy applicable environmental laws and regulations in the Pinedale Anticline
area  and  other  areas  of  operation  under  the  jurisdiction  of  the  BLM.  The  Company's  future  costs  of  complying  with  these  regulations  may  continue  to  be
significant.  Further,  any  additional  limitations  and  mitigation  measures  could  further  increase  production  costs,  delay  exploration,  development  and
production activities or curtail exploration, development and production activities altogether.

In August 1999, the BLM required an Environmental Assessment ("EA") for the potential increased density drilling in the Jonah field area. An EA is a
more limited environmental study than that conducted under an EIS. The EA was required to address the potential environmental impacts of developing the
Jonah  field  on  a  well  density  of  two  wells  per  80-acre  drilling  and  spacing  unit  as  opposed  to  the  one  well  per  80-acre  drilling  and  spacing  unit  as  was
approved in the initial Jonah field EIS approved in 1998. The new EA was completed in June 2000. With the approval of this EA and the earlier approval by
the  WOGCC  for  drilling  of  two  wells  per  80-acre  drilling  and  spacing  unit,  the  Company  was  permitted  to  drill  infill  wells  at  this  well  density  on  the
2,160 gross (1,322 net) acres then owned by the Company in the Jonah field. Subsequently, various other operators have received approval for the drilling of
increased density wells in pilot areas at well densities ranging from four wells per 80-acre drilling and spacing unit to sixteen wells per drilling and spacing
unit.  Results  of  all  of  these  pilot  projects  were  utilized  in  acquiring  approval  from  the  WOGCC  in  November  2004  to  increase  the  overall  density  of
development for the Jonah field to eight wells per 80-acre drilling and spacing unit.

12

 
 
Table of Contents

The BLM prepared a new EIS covering the Jonah field to assess the impact of increased density development and define the parameters under which
this  increased  density  development  will  be  allowed  to  proceed.  The  draft  EIS  was  made  available  in  February  2005  and  the  final  ROD  was  issued  on
March 14, 2006. Key components of the ROD require an annual operations plan that includes all previous year activity including the number of wells drilled,
total new surface disturbance by well pads, roads, and pipelines, and current status of all reclamation activity. Also required is a plan of development for the
upcoming year reflecting the planned number of wells to be drilled and an estimate of new surface disturbance and reclamation activity. Other components
include  a  drilling  rig  forecast,  emission  reduction  report,  annual  water  well  monitoring  reports,  a  three-year  operational  forecast  and  the  use  of  flareless-
completion technology to reduce noise, visual impacts and air emissions, including greenhouse gases as well as other monitoring and mitigation measures.

During  the  period  from  2003  through  year  end  2011,  Ultra  and  other  operators  in  the  Pinedale  field  received  approval  from  the  WOGCC  to  drill
increased density and pilot project wells in several areas in the Lance Pool across the Pinedale field. During 2011, based on results of its 5-acre wells drilled in
2010,  Ultra  sought  and  obtained  approval  from  the  WOGCC  to  file  for  development  of  its  acreage  in  Pinedale  at  a  well  density  of  32  wells  per  160-acre
government quarter section (5-acre equivalent). Current spacing in the Jonah field is eight wells per 80-acre drilling and spacing unit (10-acre spacing) with
several pilots testing spacing at 16 wells per 80-acre drilling and spacing unit (5-acre spacing).

Ultra,  Shell  and  Questar  ("Proponents")  submitted  a  development  proposal  for  the  Pinedale  field,  which  includes  broad  application  of  operations
principles being evaluated in the demonstration project area. The Proponents entered into a memorandum of understanding with the BLM to commence the
preparation of a supplemental EIS, or SEIS, for year-round access in the Pinedale field. The SEIS process included assessment of alternative considerations
and  mitigation  requirements  that  were  considered  as  alternatives,  or  in  addition,  to  those  included  in  the  proposal.  The  proposal  included  commitments  to
reduce  surface  disturbance  by  utilizing  fewer  overall  pads  and  drilling  more  directional  wells  than  called  for  in  the  2000  Pinedale  Anticline  Project  Area
("PAPA") ROD.

The final ROD was granted on September 9, 2008. The 2008 SEIS ROD allows, among other things, for full field development from no more than
600 well pads field-wide, as well as year-round development and delineation activity within big game (pronghorn and mule deer) and greater sage-grouse
seasonal use areas. Further, the Proponents agreed to implement numerous individual mitigation components. These commitments include i) the use of a full-
field liquids gathering system, ii) the use of advanced rig engine emission reduction technology by at least 80% of the Company's 2005 rig emission levels,
iii) a mitigation and monitoring fund to address mitigation efforts to minimize impacts from energy development, and iv) additional funding for ground water
monitoring on the PAPA. Additionally, ten-year planning and annual meetings with BLM and appropriate state agencies will allow for proper community
planning.

Also as part of the 2008 SEIS ROD, Ultra has offered to suspend additional activity for at least five years from the signing of the SEIS ROD on certain
leases.  After  the  five-year  period,  leases  under  federal  suspension  and/or  "no  surface"  occupancy  will  be  considered  for  conversion  to  "available  for
development" when a comparable acreage in the core area of the PAPA has been returned to a functioning habitat.

In  2007  and  2008  Ultra  entered  five  groundwater  supply  wells  into  the  Wyoming  Department  of  Environmental  Quality  Voluntary  Remediation
Program ("VRP"). These wells exceeded the Department of Environmental Quality's ("DEQ") minimum clean-up levels ("MCL"). Four of the five wells are
now non-detect or below the MCL. The remaining well has low levels of contaminants and a remediation plan has been submitted to the DEQ for this well.
Ultra encountered another water well that exceeded the MCL. This well was remediated and the contaminate levels were non-detect before it was entered into
the VRP.

In July 2009, Ultra, along with Shell and Questar, were awarded the BLM's 2009 Environmental Best Management Practices Award for Responsible

Stewardship of Air Resources in the PAPA.

Regulation

Oil and Gas Regulation

The availability of a ready market for oil and natural gas production depends upon numerous factors beyond the Company's control. These factors may
include,  among  other  things,  federal,  state  and  local  regulation  of  oil  and  natural  gas  production  and  transportation,  including  regulations  governing
environmental quality, pollution control and limits on allowable rates of production by a well or proration unit; the amount of oil and natural gas available for
sale; the availability of adequate pipeline and other transportation and processing facilities; and the marketing of competitive fuels.

Most states, and some counties and municipalities, in which the Company operates also regulate one or more of the following:

•

•

•

•

•

  The location of wells;

  The method of drilling, completing and operating wells;

  The surface use and restoration of properties upon which wells are drilled;

  The plugging and abandoning of wells; and

  Notice to surface owners and other third parties.

State and federal regulations are generally intended to prevent waste of oil and natural gas, protect rights to produce oil and natural gas between owners
in  a  common  reservoir,  control  the  amount  of  oil  and  natural  gas  produced  by  assigning  allowable  rates  of  production  and  control  contamination  of  the
environment. Pipelines and natural gas plants operated by other companies that provide midstream services to the Company are also subject to the jurisdiction
of  various  federal,  state  and  local  authorities,  which  can  affect  our  operations.  State  laws  also  regulate  the  size  and  shape  of  drilling  and  spacing  units  or
proration units governing the pooling of oil and gas properties.

States generally impose a production, ad valorem or severance tax with respect to the production and sale of oil and gas within its jurisdiction. States do

not generally regulate wellhead prices or engage in other, similar direct economic regulation, but there can be no assurance they will not do so in the future.

The Company's sales of natural gas are affected by the availability, terms and costs of transportation both in the gathering systems that transport the
natural gas from the wellhead to the interstate pipelines and in the interstate pipelines themselves. The rates, terms and conditions applicable to the interstate
transportation of natural gas by pipelines are regulated by the FERC under the Natural Gas Act, as well as under Section 311 of the Natural Gas Policy Act.
Since  1985,  the  FERC  has  issued  and  implemented  regulations  intended  to  increase  competition  within  the  natural  gas  industry  by  making  natural  gas
transportation more accessible to natural gas buyers and sellers on an open-access, non-discriminatory basis.

The Company's sales of oil are also affected by the availability, terms and costs of transportation. The rates, terms, and conditions applicable to the
interstate  transportation  of  oil  by  pipelines  are  regulated  by  the  FERC  under  the  Interstate  Commerce  Act.  The  FERC  has  implemented  a  simplified  and
generally applicable ratemaking methodology for interstate oil pipelines to fulfill the requirements of Title XVIII of the Energy Policy Act of 1992 comprised
of an indexing system to establish ceilings on interstate oil pipeline rates.

If  the  Company  conducts  operations  on  federal,  tribal  or  state  lands,  such  operations  must  comply  with  numerous  regulatory  restrictions,  including
various  operational  requirements  and  restrictions,  nondiscrimination  statutes  and  royalty  and  related  valuation  requirements.  In  addition,  some  operations
must be conducted pursuant to certain on-site security regulations, bonding requirements and applicable permits issued by the Bureau of Land Management
("BLM"),  Bureau  of  Ocean  Energy  Management,  Bureau  of  Safety  and  Environmental  Enforcement,  Bureau  of  Indian  Affairs,  tribal  or  other  applicable
federal, state and/or Indian Tribal agencies.

The Mineral Leasing Act of 1920 ("Mineral Act") prohibits ownership of any direct or indirect interest in federal onshore oil and gas leases by a foreign
citizen or a foreign corporation except through stock ownership in a corporation formed under the laws of the United States or of any U.S. State or territory,
and only if the laws, customs, or regulations of their country of origin or domicile do not deny similar or like privileges to citizens or corporations of the
United States. If these restrictions are violated, the oil and gas lease can be canceled in a proceeding instituted by the United States Attorney General. The
Company qualifies as a corporation formed under the laws of the United States or of any U.S. State or territory. Although the regulations promulgated and
administered by the BLM pursuant to the Mineral Act provide for agency designations of non-reciprocal countries, there are presently no such designations in
effect.  The  Company  owns  interests  in  numerous  federal  onshore  oil  and  gas  leases.  It  is  possible  that  holders  of  the  Company's  equity  interests  may  be
citizens of foreign countries that are determined to be non-reciprocal countries under the Mineral Act. In such event, the federal onshore oil and gas leases
held by the Company could be subject to cancellation based on such determination.

Surface Damage Acts

Several states, including Wyoming, and some tribal nations have enacted surface damage statutes. These laws are designed to compensate for damages
caused  by  oil  and  gas  development  operations.  Most  surface  damage  statutes  contain  entry  and  negotiation  requirements  to  facilitate  contact  between  the
operator and surface owners. Some also contain binding requirements for payments by the operator in connection with development operations. Costs and
delays associated with surface damage statutes could impair operational effectiveness and increase development costs.

Environmental Regulations

General.    The Company's exploration, drilling and production activities from wells and natural gas facilities, including the operation and construction
of pipelines, plants and other facilities for transporting, processing, treating or storing oil, natural gas and other products are subject to stringent federal, state
and  local  laws  and  regulations  relating  to  environmental  quality,  including  those  relating  to  oil  spills  and  pollution  control.  Although  such  laws  and
regulations can increase the cost of planning, designing, installing and operating such facilities, it is anticipated that, absent the occurrence of an extraordinary
event, compliance with them will not have a material effect upon the Company's operations, capital expenditures, earnings or competitive position.

Solid and Hazardous Waste.    The Company has previously owned or leased and currently owns or leases, numerous properties that have been used for
the exploration and production of oil and natural gas for many years. Although the Company utilized standard operating and disposal practices, hydrocarbons
or  other  solid  wastes  may  have  been  disposed  of  or  released  on  or  under  such  properties  or  on  or  under  locations  where  such  wastes  have  been  taken  for
disposal. In addition, many of these properties are or have been operated by third parties over whom the Company has no control, nor has ever had control as
to such entities' treatment of hydrocarbons or other wastes or the manner in which such substances may have been disposed of or released. State and federal
laws  applicable  to  oil  and  natural  gas  wastes  and  properties  have  gradually  become  stricter  over  time.  Under  current  and  evolving  law,  it  is  possible  the
Company  could  be  required  to  remediate  property,  including  ground  water,  containing  or  impacted  by  operations  by  the  Company  or  by  such  third  party
operators, or by previously disposed wastes including performing remedial plugging operations to prevent future, or mitigate existing, contamination.

Although oil and gas wastes generally are exempt from regulation as hazardous wastes ("Hazardous Wastes") under the federal Resource Conservation
and Recovery Act ("RCRA") and some comparable state statutes, it is possible some wastes the Company generates presently or in the future may be subject
to regulation under RCRA and state analogs. The Environmental Protection Agency ("EPA") and various state agencies have limited the disposal options for
certain wastes, including Hazardous Wastes and are considering adopting stricter disposal standards for non-hazardous wastes. Furthermore, certain wastes
generated by the Company's oil and natural gas operations that are currently exempt from treatment as Hazardous Wastes may in the future be designated as
Hazardous Wastes under the RCRA or other applicable statutes, and therefore be subject to more rigorous and costly operating and disposal requirements.

Safe  Drinking  Water  Act.        Many  of  the  Company's  exploration  and  production  operations  depend  on  the  use  of  hydraulic  fracturing  to  enhance
production from oil and gas wells. Congress has periodically considered legislation to amend the federal Safe Drinking Water Act to remove the exemption
from permitting and regulation provided to injection for hydraulic fracturing and to require the disclosure and reporting of the chemicals used in hydraulic
fracturing. This type of federal legislation, if adopted, could lead to additional regulation and permitting requirements that could result in operational delays
making it more difficult to perform hydraulic fracturing and increasing our costs of compliance and operating costs.

In addition, EPA has recently been taking activity to assert federal regulatory authority over hydraulic fracturing using diesel under the Safe Drinking
Water Act's Underground Injection Control Program. Further, in March 2010, the EPA announced that it would conduct a wide-ranging study on the effects of
hydraulic  fracturing  on  drinking  water  resources.  Interim  results  of  the  study  are  expected  in  2012,  with  final  results  expected  in  2014.  In  addition,  in
December 2011, the EPA published a draft report in which it asserts that hydraulic fracturing caused groundwater pollution in a natural gas field in Wyoming
(not a field in which the Company owns any interest); this report has been publicly criticized by industry and government officials, including the Governor of
Wyoming; it remains subject to review and public comment. The agency also announced that one of its enforcement initiatives for 2011 to 2013 would be to
focus on environmental compliance by the energy extraction sector. This study and enforcement initiative could result in additional regulatory scrutiny that
could make it difficult to perform hydraulic fracturing and increase our costs of compliance and doing business.

Superfund.        Under  the  federal  Comprehensive  Environmental  Response,  Compensation  and  Liability  Act  ("CERCLA"),  also  known  as  the
"Superfund" law, liability, generally, is joint and several for costs of investigation and remediation and for natural resource damages, without regard to fault or
the legality of the original conduct, on certain classes of persons with respect to the release into the environment of substances designated under CERCLA as
hazardous  substances  ("Hazardous  Substances").  These  classes  of  persons,  or  so-called  potentially  responsible  parties  ("PRP"),  include  current  and  certain
past owners and operators of a facility where there has been a release or threat of release of a Hazardous Substance and persons who disposed of or arranged
for the disposal of the Hazardous Substances found at such a facility. CERCLA also authorizes the EPA and, in some cases, third parties to take actions in
response  to  releases  and  threats  of  releases  to  protect  the  public  health  or  the  environment  and  to  seek  to  recover  from  the  PRP  the  costs  of  such  action.
Although CERCLA generally exempts "petroleum" from the definition of Hazardous Substance, in the course of its operations, the Company has generated
and  will  generate  wastes  that  fall  within  CERCLA's  definition  of  Hazardous  Substances.  The  Company  may  also  be  an  owner  or  operator  of  facilities  on
which Hazardous Substances have been released. The Company may be responsible under CERCLA for all or part of the costs to clean up facilities at which
such substances have been released and for natural resource damages, as a past or present owner or operator or as an arranger. Many states have comparable
laws  imposing  liability  on  similar  classes  of  persons  for  releases,  including  for  releases  of  materials  that  may  not  be  included  in  CERCLA's  definition  of
Hazardous Substances. To its knowledge, the Company has not been named a PRP under CERCLA (or any comparable state law) nor have any prior owners
or operators of its properties been named as PRPs related to their ownership or operation of such property.

National Environmental Policy Act.    The federal National Environmental Policy Act provides that, for major federal actions significantly affecting the
quality of the human environment, the federal agency taking such action must prepare an environmental impact statement (EIS). In the EIS, the agency is
required  to  evaluate  alternatives  to  the  proposed  action  and  the  environmental  impacts  of  the  proposed  action  and  of  such  alternatives.  Actions  of  the
Company, such as drilling on federal lands, to the extent the drilling requires federal approval, may trigger the requirements of the National Environmental
Policy  Act,  including  the  requirement  that  an  EIS  be  prepared.  The  requirements  of  the  National  Environmental  Policy  Act  may  result  in  increased  costs,
significant delays and the imposition of restrictions or obligations on the Company's activities, including but not limited to the restricting or prohibiting of
drilling.

Oil Pollution Act.    The Oil Pollution Act of 1990 ("OPA"), which amends and augments oil spill provisions of the Clean Water Act ("CWA"), imposes
certain  duties  and  liabilities  on  certain  "responsible  parties"  related  to  the  prevention  of  oil  spills  and  damages  resulting  from  such  spills  in  or  threatening
United States waters or adjoining shorelines. A liable "responsible party" includes the owner or operator of a facility, vessel or pipeline that is a source of an
oil discharge or that poses the substantial threat of discharge or, in the case of offshore facilities, the lessee or permittee of the area in which a discharging
facility is located. OPA assigns liability, which generally is joint and several, without regard to fault, to each liable party for oil removal costs and for a variety
of public and private damages. Although defenses and limitations exist to the liability imposed by OPA, they are limited. In the event of an oil discharge or
substantial threat of discharge, the Company could be liable for costs and damages.

Air Emissions.    The Company's operations are subject to local, state and federal regulations for the control of emissions from sources of air pollution.
Federal and state laws generally require new and modified sources of air pollutants to obtain permits prior to commencing construction, which may require,
among other things, stringent, technical controls. Other federal and state laws designed to control hazardous (toxic) air pollutants might require installation of
additional controls. Administrative agencies can bring actions for failure to comply with air pollution regulations or permits and generally enforce compliance
through administrative, civil or criminal enforcement actions, which may result in fines, injunctive relief and imprisonment.

On  July  28,  2011,  EPA  proposed  a  rule  to  subject  oil  and  gas  operations  to  regulation  under  the  New  Source  Performance  Standards  (NSPS)  and
National  Emission  Standards  for  Hazardous  Air  Pollutants  (NESHAP)  programs  under  the  Clean  Air  Act,  and  to  impose  new  and  amended  requirements
under both programs. Under the proposal, EPA would, among other things, amend standards applicable to natural gas processing plants and would expand the
NSPS  to  include  all  oil  and  gas  operations,  imposing  requirements  on  those  operations.  EPA  is  also  proposing  NSPS  standards  for  completions  of
hydraulically fractured gas wells. The proposed standards include the reduced emission completion techniques. The NESHAPS proposal includes maximum
achievable  control  technology  (MACT)  standards  for  certain  glycol  dehydrators  and  storage  vessels,  and  revises  applicability  provisions,  alternative  test
protocols and the availability of the startup, shutdown and maintenance exemption. EPA is under a court order to finalize the rules, with the current deadline
of April 3, 2012. Should these rules become final and applicable to our operations, they could result in increased operating and compliance costs, increased
regulatory burdens and delays in our operations.

Clean Water Act.    The Clean Water Act ("CWA") restricts the discharge of wastes, including produced waters and other oil and natural gas wastes,
into  waters  of  the  United  States,  a  term  broadly  defined  to  include,  among  other  things,  certain  wetlands.  Under  the  Clean  Water  Act,  permits  must  be
obtained  for  the  routine  discharge  of  pollutants  into  waters  of  the  United  States.  The  CWA  provides  for  administrative,  civil  and  criminal  penalties  for
unauthorized discharges, both routine and accidental, of pollutants and of oil and hazardous substances. It imposes substantial potential liability for the costs
of  removal  or  remediation  associated  with  discharges  of  oil  or  hazardous  substances.  State  laws  governing  discharges  to  water  also  provide  varying  civil,
criminal and administrative penalties and impose liabilities in the case of a discharge of petroleum or its derivatives, or other hazardous substances, into state
waters.  In  addition,  the  EPA  has  promulgated  regulations  that  may  require  permits  to  discharge  storm  water  runoff,  including  discharges  associated  with
construction activities.

RCRA  and  comparable  state  and  local  programs  impose  requirements  on  the  management,  treatment,  storage  and  disposal  of  both  hazardous  and
nonhazardous solid wastes. Many of the wastes that we generate are currently exempt from hazardous waste regulation under RCRA, but may be subject to
state  and  local  regulation  or  could  in  the  future  lose  their  RCRA  exemption,  which  would  result  in  more  rigorous  and  costly  management  and  disposal
requirements.

Endangered Species Act.    The Endangered Species Act ("ESA") was established to protect endangered and threatened species. Pursuant to that act, if a
species is listed as threatened or endangered, restrictions may be imposed on activities adversely affecting that species' habitat. Similar protections are offered
to migratory birds

17

 
 
Table of Contents

under the Migratory Bird Treaty Act. The Company conducts operations on federal and other oil and natural gas leases that have species, such as raptors, that
are listed and species, such as sage grouse, that could be listed as threatened or endangered under the ESA. The U.S. Fish and Wildlife Service must also
designate the species' critical habitat and suitable habitat as part of the effort to ensure survival of the species. A critical habitat or suitable habitat designation
or the mere presence of threatened or endangered species could result in further material restrictions to federal land use and may materially delay or prohibit
land access for oil and natural gas development. If the Company were to have a portion of its leases designated as critical or suitable habitat, it may adversely
impact the value of the affected leases.

OSHA  and  other  Regulations.        The  Company  is  subject  to  the  requirements  of  the  federal  Occupational  Safety  and  Health  Act  ("OSHA")  and
comparable state statutes. The OSHA hazard communication standard, the EPA community right-to-know regulations under Title III of CERCLA and similar
state statutes require a company to organize and/or disclose information about hazardous materials used or produced in its operations.

Climate Change Legislation.    Laws and regulations relating to climate change and greenhouse gases ("GHGs"), including methane and carbon dioxide,
may  be  adopted  and  could  cause  the  Company  to  incur  material  expenses  in  complying  with  them.  In  June  2010,  EPA  published  its  GHG  tailoring  rule
phasing in federal prevention of significant deterioration (PDS) permit requirements for new sources and modifications, and Title V operating permits for all
sources,  that  have  the  potential  to  emit  specific  quantities  of  GHGs.  These  permitting  provisions,  when  they  become  applicable  to  our  operations,  could
require controls or other measures to reduce GHG emissions from new or modified sources, and the Company could incur additional costs to satisfy those
requirements.  In  November  2010,  EPA  published  a  rule  establishing  GHG  reporting  requirements  for  sources  in  the  petroleum  and  natural  gas  industry,
requiring  those  sources  to  monitor,  maintain  records  on,  and  annually  report  their  GHG  emissions,  with  the  first  annual  report,  for  2011,  being  due  in
September  2012.  Although  the  rule  does  not  limit  the  amount  of  GHGs  that  can  be  emitted,  it  could  require  us  to  incur  significant  costs  to  monitor,  keep
records of, and report GHG emissions associated with our operations.

In addition to possible federal regulation, a number of states, individually and regionally, also are considering or have implemented GHG regulatory
programs.  These  or  other  potential  federal  and  state  initiatives  may  result  in  so-called  cap-and-trade  programs,  under  which  overall  GHG  emissions  are
limited  and  GHG  emissions  are  then  allocated  and  sold,  and  possibly  other  regulatory  requirements,  that  could  result  in  the  Company  incurring  material
expenses to comply, e.g., by being required to purchase or to surrender allowances for GHGs resulting from its operations. These regulatory initiatives also
could adversely affect the marketability of the oil and natural gas the Company produces.

The Company believes that it is in substantial compliance with current applicable environmental laws and regulations and that continued compliance

with existing requirements will not have a material adverse impact on the Company.

Employees

As of December 31, 2011, the Company had 116 full-time employees, including officers.

Item 1A.     Risk Factors. 

Our reserve estimates may turn out to be incorrect if the assumptions upon which these estimates are based are inaccurate. Any material inaccuracies
in these reserve estimates or underlying assumptions will materially affect the quantities and present value of our reserves.

There  are  numerous  uncertainties  inherent  in  estimating  quantities  of  proved  reserves  and  projected  future  rates  of  production  and  timing  of
development expenditures, including many factors beyond our control. The reserve data and standardized measures set forth herein represent only estimates.
Reserve engineering is a

18

 
 
 
Table of Contents

subjective process of estimating underground accumulations of oil and natural gas that cannot be measured in an exact way and the accuracy of any reserve
estimate  is  a  function  of  the  quality  of  available  data  and  of  engineering  and  geological  interpretation  and  judgment.  As  a  result,  estimates  of  different
engineers  often  vary.  In  addition,  drilling,  testing  and  production  data  acquired  subsequent  to  the  date  of  an  estimate  may  justify  revising  such  estimates.
Accordingly, reserve estimates are often different from the quantities of oil and natural gas that are ultimately recovered. Further, the estimated future net
revenues from proved reserves and the present value thereof are based upon certain assumptions, including geologic success, prices, future production levels
and costs that may not prove correct over time. Predictions of future production levels, prices and future operating costs are subject to great uncertainty, and
the meaningfulness of such estimates is highly dependent upon the accuracy of the assumptions upon which they are based.

The present value, discounted at 10%, of the pre-tax future net cash flows attributable to our net proved reserves included in this report should not be
considered as the market value of the reserves attributable to our properties. In accordance with SEC requirements, we base the present value, discounted at
10%, of the pre-tax future net cash flows attributable to our net proved reserves on the average oil and natural gas prices during the 12-month period before
the ending date of the period covered by this report determined as an unweighted, arithmetic average of the first-day-of the-month price for each month within
such  period,  adjusted  for  quality  and  transportation.  The  costs  to  produce  the  reserves  remain  constant  at  the  costs  prevailing  on  the  date  of  the  estimate.
Actual  current  and  future  prices  and  costs  may  be  materially  higher  or  lower.  In  addition,  the  10%  discount  factor,  which  the  SEC  requires  us  to  use  in
calculating our discounted future net revenues for reporting purposes, may not be the most appropriate discount factor based on our cost of capital from time
to time and/or the risks associated with our business.

Competitive industry conditions may negatively affect our ability to conduct operations.

We  compete  with  numerous  other  companies  in  virtually  all  facets  of  our  business.  Our  competitors  in  development,  exploration,  acquisitions  and
production  include  major  integrated  oil  and  natural  gas  companies  as  well  as  numerous  independents,  including  many  that  have  significantly  greater
resources. Therefore, competitors may be able to pay more for desirable leases and evaluate, bid for and purchase a greater number of properties or prospects
than  the  financial  or  personnel  resources  of  the  Company  permit.  We  also  compete  for  the  materials,  equipment  and  services  that  are  necessary  for  the
exploration, development and operation of our properties. Our ability to increase reserves in the future will be dependent on our ability to select and acquire
suitable prospects for future exploration and development.

Factors that affect our ability to compete in the marketplace include:

•

•

•

•

•

  our access to the capital necessary to drill and complete wells and acquire properties;

  our ability to acquire and analyze seismic, geological and other information relating to a property;

  our ability to retain the personnel necessary to properly evaluate seismic and other information relating to a property;

  our ability to procure materials, equipment and services required to explore, develop and operate our properties; and

  our ability to access pipelines, and the locations of facilities used to produce and transport oil and natural gas production.

Factors beyond our control affect our ability to effectively market production and may ultimately affect our financial results.

The ability to market oil and natural gas depends on numerous factors beyond our control. These factors include:

•

  the extent of domestic production and imports of oil and natural gas;

19

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

•

•

•

•

•

•

•

  the availability of pipeline capacity, including facilities owned and operated by third parties;

  the proximity of natural gas production to natural gas pipelines;

  the effects of inclement weather;

  the demand for oil and natural gas by utilities and other end users;

  the availability of alternative fuel sources;

  state and federal regulations of oil and natural gas marketing and transportation; and

  federal regulation of natural gas sold or transported in interstate commerce.

Because of these factors, we may be unable to market all of the oil and natural gas that we produce. In addition, we may be unable to obtain favorable

prices for the oil and natural gas we produce.

Our derivative transactions may limit our gains and expose us to other risks.

We enter into transactions with derivative instruments from time to time to manage our exposure to commodity price risks. These transactions limit our
potential gains if commodity prices rise above the levels established by our derivative instruments. These transactions may also expose us to other risks of
financial  losses,  for  example,  if  our  production  is  less  than  we  anticipated  at  the  time  we  entered  into  a  derivative  instrument  or  if  a  counterparty  to  our
derivative instruments fails to perform the contracts.

The adoption of derivatives legislation and regulations related to derivative contracts could have an adverse impact on our ability to hedge risks
associated with our business.

During 2010, the President signed into law the Dodd–Frank Wall Street Reform and Consumer Protection Act (the "Act"). Among other things, the Act
requires the Commodity Futures Trading Commission and the SEC to enact regulations affecting derivative contracts, including the derivative contracts we
use to hedge our exposure to price volatility through the over-the-counter market. We cannot predict the content of these regulations or the effect that these
regulations will have on our hedging activities. Of particular concern, the Act does not explicitly exempt end users (such as us) from the requirement to use
cleared  exchanges,  rather  than  hedging  over-the-counter,  and  the  requirements  to  post  margin  in  connection  with  hedging  activities.  If  the  regulations
ultimately adopted require that we post margin for our hedging activities or require our counterparties to hold margin or maintain capital levels, the cost of
which  could  be  passed  through  to  us,  or  impose  other  requirements  that  are  more  burdensome  than  current  regulations,  our  hedging  would  become  more
expensive and we may decide to alter our hedging strategy.

A decrease in oil and natural gas prices may adversely affect our results of operations and financial condition.

Energy commodity prices in general, and our regional prices in particular, have been historically highly volatile, and such high levels of volatility are
expected  to  continue  in  the  future.  We  cannot  accurately  predict  the  market  prices  that  we  will  receive  for  the  sale  of  our  natural  gas,  condensate,  or  oil
production.

Oil and natural gas prices are subject to a variety of additional factors beyond our control, which include, but are not limited to: changes in the supply of
and demand for oil and natural gas; market uncertainty; weather conditions in the United States; the condition of the United States economy; the actions of the
Organization of Petroleum Exporting Countries; governmental regulation; political stability in the Middle East and elsewhere; the foreign supply of oil and
natural  gas;  the  price  of  foreign  oil  and  natural  gas  imports;  the  availability  of  alternate  fuel  sources;  and  transportation  interruption.  Any  substantial  and
extended decline in the price of oil or natural gas could have an adverse effect on the carrying value of our proved reserves, borrowing capacity, our ability to
obtain additional capital, and the Company's revenues, profitability and cash flows from operations.

Volatile  oil  and  natural  gas  prices  make  it  difficult  to  estimate  the  value  of  producing  properties  for  acquisition  and  divestiture  and  often  cause
disruption in the market for oil and natural gas producing properties, as buyers and sellers have difficulty agreeing on such value. Price volatility also makes it
difficult to budget for and project the return on acquisitions and development and exploitation projects.

A substantial portion of our reserves and production is natural gas. Prices for natural gas have been lower in recent years than at various times in the
past and may remain lower in the future. Sustained low prices for natural gas may adversely effect our operational and financial condition.

Natural gas prices have been lower in recent years than at various times in the past. These lower prices may be the result of increased supply resulting
from among other things, increased drilling in unconventional reservoirs and/or lower demand resulting from reduced economic activity associated with the
recent  recession.  Natural  gas  prices  may  remain  at  current  levels,  or  fall  to  lower  levels,  in  the  future.  Approximately  96%  of  our  estimated  net  proved
reserves is natural gas, and 97% of our production in 2011 was natural gas. Although we expect operations on properties we currently own to be profitable at
natural  gas  prices  in  effect  during  the  past  year,  a  period  of  sustained  low  natural  gas  prices  could  have  an  adverse  effect  on  our  results  of  operation  and
financial condition.

Compliance with environmental and other government regulations could be costly and could negatively impact our production.

Our operations are subject to numerous laws and regulations relating to environmental protection. These laws and regulations may:

•

•

•

•

  require that we acquire permits before developing our properties;

  restrict the substances that can be released into the environment in connection with drilling and production activities;

  limit or prohibit drilling activities on protected areas such as wetlands or wilderness areas; and

  require remedial measures to mitigate pollution from former operations, such as plugging abandoned wells.

Under  these  laws  and  regulations  or  under  the  common  law,  the  Company  could  be  liable  for  personal  injury  and  clean-up  costs  and  other
environmental and property damages, as well as administrative, civil and criminal penalties. The Company could also be affected by more stringent laws and
regulations adopted in the future, including any related to climate change, greenhouse gases and hydraulic fracturing. We maintain limited insurance coverage
for sudden and accidental environmental damages, but do not maintain insurance coverage for the full potential liability that could be caused by accidental
environmental  damages.  Accordingly,  we  may  be  subject  to  liability  in  excess  of  our  insurance  coverage  or  may  be  required  to  cease  production  from
properties in the event of environmental damages.

A significant percentage of our operations are conducted on federal and state lands. These operations are subject to a wide variety of regulations as well
as other permits and authorizations which must be obtained from and issued by state and federal agencies. To conduct these operations, we may be required to
file applications for permits, seek agency authorizations and comply with various other statutory and regulatory requirements. Complying with any of these
requirements may adversely affect our ability to complete our drilling programs at the costs and in the time periods anticipated.

Climate change legislation or regulations restricting emissions of "greenhouse gases" could result in increased operating costs and reduced demand
for the oil and gas we produce.

On December 15, 2009, the EPA officially published its findings that emissions of carbon dioxide, methane and other gases which the EPA refers to as
"greenhouse gases" ("GHGs") create risks to public health and the environment because emissions of such gases are, according to the EPA, contributing to
warming of the earth's

21

 
 
 
 
 
 
 
 
 
 
Table of Contents

atmosphere  and  other  climatic  changes.  These  findings  allow  the  EPA  to  adopt  and  implement  regulations  that  would  restrict  emissions  of  GHGs  under
existing provisions of the federal Clean Air Act. Accordingly, the EPA has proposed two sets of regulations that would require a reduction in emissions of
GHGs from motor vehicles and could trigger permit review for GHG emissions from certain stationary sources.

In addition, on October 30, 2009, the EPA published a final rule requiring the reporting of GHG emissions from specified large GHG emission sources
in the United States beginning in 2011 for emissions occurring in 2010. On November 30, 2010, the EPA published its amendments to the GHG reporting rule
to  include  onshore  and  offshore  oil  and  natural  gas  production  facilities  and  onshore  oil  and  natural  gas  processing,  transmission,  storage  and  distribution
facilities, which may include facilities we operate. Reporting of GHG emissions from such facilities will be required on an annual basis beginning in 2012 for
emissions occurring in 2011. We will have to incur costs associated with this reporting obligation.

In addition, the United States Congress has considered legislation to reduce emissions of GHGs and many states have already taken legal measures to
reduce  or  measure  GHG  emission  levels,  often  involving  the  planned  development  of  GHG  emission  inventories  and/or  regional  cap  and  trade  programs.
Most  of  these  cap  and  trade  programs  require  major  sources  of  emissions  or  major  producers  of  fuels  to  acquire  and  surrender  emission  allowances.  The
number of allowances available for purchase is reduced each year in an effort to reduce overall GHG emissions. The cost of these allowances could escalate
significantly  over  time.  The  adoption  and  implementation  of  any  legislation  or  regulatory  programs  imposing  GHG  reporting  obligations  on,  or  limiting
emissions of GHGs from, our equipment and operations could require us to incur costs to reduce emissions of GHGs associated with our operations or could
adversely affect demand for the oil and natural gas that we produce.

Potential physical effects of climate change could adversely affect our operations and cause us to incur significant costs in preparing for or responding
to those effects.

In  an  interpretative  guidance  on  climate  change  disclosures,  the  SEC  indicates  that  climate  change  could  have  an  effect  on  the  severity  of  weather
(including hurricanes and floods), sea levels, the arability of farmland, and water availability and quality. If such effects were to occur, our exploration and
production  operations,  including  the  hydraulic  fracturing  of  our  wells,  have  the  potential  to  be  adversely  affected.  Potential  adverse  effects  could  include
disruption  of  our  production  activities,  including,  for  example,  damages  to  our  facilities  from  powerful  winds  or  increases  in  our  costs  of  operation  or
reductions  in  the  efficiency  of  our  operations,  as  well  as  potentially  increased  costs  for  insurance  coverages  in  the  aftermath  of  such  effects.  Significant
physical  effects  of  climate  change  could  also  have  an  indirect  effect  on  our  financing  and  operations  by  disrupting  the  transportation  or  process  related
services  provided  by  midstream  companies,  service  companies  or  suppliers  with  whom  we  have  a  business  relationship.  We  may  not  be  able  to  recover
through insurance some or any of the damages, losses or costs that may result from potential physical effects of climate change.

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

Hydraulic fracturing is used to stimulate production of hydrocarbons, particularly natural gas, from tight formations. 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  but  is  not  subject  to  regulation  at  the  federal  level  (except  for  fracturing  activity  involving  the  use  of  diesel).  The  EPA  has
commenced a study of the potential environmental impacts of hydraulic fracturing activities, with interim results of the study anticipated to be available by
late 2012, and final results anticipated in 2014. In addition, in December 2011, the EPA published a draft report in which it asserts that hydraulic fracturing
caused groundwater pollution in a natural gas field in Wyoming (not a field in which the Company owns an interest); this report has been publicly criticized
by industry and by government officials, including the Governor of Wyoming; it remains subject to review and public comment. A committee of the U.S.
House of

22

 
 
Table of Contents

Representatives  is  also  conducting  an  investigation  of  hydraulic  fracturing  practices.  Legislation  was  introduced  before  Congress  to  provide  for  federal
regulation of hydraulic fracturing and to require disclosure of the chemicals used in the fracturing process. In addition, some states have adopted, and other
states are considering adopting, regulations that could restrict hydraulic fracturing in certain circumstances. Pennsylvania has adopted a variety of regulations
limiting  how  and  where  fracturing  can  be  performed.  Wyoming  has  adopted  regulations  requiring  us  to  provide  detailed  information  about  wells  we
hydraulically fracture in that state. Any other new laws or regulations that significantly restrict hydraulic fracturing could make it more difficult or costly for
us to perform hydraulic fracturing activities and thereby affect our determination of whether a well is commercially viable. In addition, if hydraulic fracturing
is  regulated  at  the  federal  level,  our  fracturing  activities  could  become  subject  to  additional  permit  requirements  or  operational  restrictions  and  also  to
associated  permitting  delays  and  potential  increases  in  costs.  We  have  conducted  hydraulic  fracturing  operations  on  most  of  our  existing  wells,  and  we
anticipate conducting hydraulic fracturing operations on substantially all of our future wells. As a result, restrictions on hydraulic fracturing could reduce the
amount of oil and natural gas that we are ultimately able to produce in commercial quantities.

We may not be able to obtain funding on acceptable terms or at all.

Global financial markets and economic conditions have been disrupted and volatile due to a variety of factors. As a result, the cost of raising money in
the debt and equity capital markets and the availability of funds from those markets is unpredictable. Although we successfully raised capital during 2011, we
may not be successful in the future. In addition, lending counterparties under existing revolving credit facilities and other debt instruments may be unwilling
or unable to meet their funding obligations. Due to these factors, we cannot be certain that new debt or equity financing will be available on acceptable terms.
If funding is not available when needed, or is available only on unfavorable terms, we may be unable to meet our obligations as they come due and we may be
unable to execute our growth strategy, take advantage of other business opportunities or respond to competitive pressures, any of which could have a material
adverse effect on our revenues and results of operations.

We may not be able to replace our reserves or generate cash flows if we are unable to raise capital. We will be required to make substantial capital
expenditures to develop our existing reserves and to discover new oil and gas reserves.

Our ability to continue exploration and development of our properties and to replace reserves may be dependent upon our ability to continue to raise
significant  additional  financing,  including  debt  financing  or  obtain  other  potential  arrangements  with  industry  partners  in  lieu  of  raising  financing.  Any
arrangements that may be entered into could be expensive to us. There can be no assurance that we will be able to raise additional capital in light of factors
such as the market demand for our securities, the state of financial markets for independent oil and gas companies (including the markets for debt), oil and
natural gas prices and general market conditions. See "Management's Discussion and Analysis of Financial Condition and Results of Operations — Liquidity
and Capital Resources" for a discussion of our capital budget.

We  expect  to  continue  using  our  bank  credit  facility  to  borrow  funds  to  supplement  our  available  cash  flow.  The  loan  commitment  and  aggregate
amount of money we can borrow under the credit facility and from other sources is revised from time to time based on certain restrictive covenants. A change
in our ability to meet the restrictive covenants might limit our ability to borrow. If this occurred, we may have to sell assets or seek substitute financing. We
can make no assurances that we would be successful in selling assets or arranging substitute financing. For a description of the bank credit facility and its
principal  terms  and  conditions,  see  "Management's  Discussion  and  Analysis  of  Financial  Condition  and  Results  of  Operations  —  Liquidity  and  Capital
Resources."

Our operations may be interrupted by severe weather or drilling restrictions.

Our  operations  are  conducted  primarily  in  the  Rocky  Mountain  region  of  the  United  States  and  in  the  north-central  Pennsylvania  area  of  the
Appalachian Basin. The weather in these areas can be extreme and can cause interruption in our exploration and production operations. Severe weather can
result  in  damage  to  our  facilities  entailing  longer  operational  interruptions  and  significant  capital  investment.  Likewise,  our  operations  are  subject  to
disruption from winter storms and severe cold, which can limit operations involving fluids and impair access to our facilities.

Unless we are able to replace reserves which we have produced, our cash flows and production will decrease over time.

Our  future  success  depends  on  our  ability  to  find,  develop  and  acquire  additional  oil  and  gas  reserves  that  are  economically  recoverable.  Without
successful exploration, development or acquisition activities, our reserves and production will decline. We can give no assurance that we will be able to find,
develop or acquire additional reserves at acceptable costs.

We are exposed to operating hazards and uninsured risks that could adversely impact our results of operations and cash flow.

The  oil  and  natural  gas  business  involves  a  variety  of  operating  risks,  including  fire,  explosion,  pipe  failure,  casing  collapse,  abnormally  pressured
formations, and environmental hazards such as oil spills, natural gas leaks, discharges of toxic gases, underground migration and surface spills or mishandling
of fracture fluids, including chemical additives. The occurrence of any of these events with respect to any property we own or operate (in whole or in part)
could have a material adverse impact on us. We and the operators of our properties maintain insurance in accordance with customary industry practices and in
amounts that management believes to be reasonable. However, insurance coverage is not always economically feasible and is not obtained to cover all types
of operational risks. The occurrence of a significant event that is not fully insured could have a material adverse effect on our financial condition.

There are risks associated with our drilling activity that could impact our results of operations.

Our oil and natural gas operations are subject to all of the risks and hazards typically associated with drilling for, and production and transportation of,
oil and natural gas. These risks include the necessity of spending large amounts of money for identification and acquisition of properties and for drilling and
completion of wells. In the drilling and completing of exploratory or development wells, failures and losses may occur before any deposits of oil or natural
gas  are  found.  The  presence  of  unanticipated  pressure  or  irregularities  in  formations,  blow-outs  or  accidents  may  cause  such  activity  to  be  unsuccessful,
resulting  in  a  loss  of  our  investment  in  such  activity  and  possible  liabilities.  If  oil  or  natural  gas  is  encountered,  there  can  be  no  assurance  that  it  can  be
produced in quantities sufficient to justify the cost of continuing such operations or that it can be marketed satisfactorily.

Our decision to drill a prospect is subject to a number of factors which may alter our drilling schedule or our plans to drill at all.

A  prospect  is  an  area  in  which  our  geoscientists  have  identified  what  they  believe,  based  on  available  seismic  and  geological  information,  to  be
indications  of  hydrocarbons.  Our  prospects  are  in  various  stages  of  review.  Whether  or  not  we  ultimately  drill  our  prospects  depends  on  many  factors,
including but not limited to: receipt of additional seismic data or reprocessing of existing data; material changes in oil or natural gas prices; the costs and
availability of drilling equipment; success or failure of wells drilled in similar formations or which would use the same production facilities; the availability
and cost of capital; changes in the estimates of costs to drill or complete wells; decisions of our joint working interest owners; and regulatory and permitting
requirements. It is possible that these factors and others may cause us to alter our drilling schedule or determine that a prospect should not be pursued at all.

Table of Contents

If oil and natural gas prices decrease, we may be required to write down the carrying value of our oil and gas properties.

We follow the full cost method of accounting for our oil and gas properties. A separate cost center is maintained for expenditures applicable to each
country in which we conduct exploration and/or production activities. Under such method, the net book value of properties on a country-by-country basis, less
related  deferred  income  taxes,  may  not  exceed  a  calculated  "ceiling."  The  ceiling  is  the  estimated  after  tax  future  net  revenues  from  proved  oil  and  gas
properties, discounted at 10% per year. Discounted future net revenues are estimated using oil and natural gas spot prices based on the average price during
the preceding 12-month period determined as an unweighted, arithmetic average of the first-day-of-the-month price for each month within such period, except
for changes which are fixed and determinable by existing contracts. The net book value is compared to the ceiling on a quarterly basis. The excess, if any, of
the net book value above the ceiling is required to be written off as an expense. Under SEC full cost accounting rules, any write-off recorded may not be
reversed  even  if  higher  oil  and  natural  gas  prices  increase  the  ceiling  applicable  to  future  periods.  Future  price  decreases  could  result  in  reductions  in  the
carrying value of such assets and an equivalent charge to earnings.

We have limited control over activities conducted on properties we do not operate.

We own interests in properties that are operated by third parties. The success, timing and costs of drilling, completion, and other development activities
on our non-operated properties depend on a number of factors that are beyond our control. Because we have only a limited ability to influence and control the
operations of our non-operated properties, we can give no assurances that we will realize our targeted returns with respect to those properties.

We may fail to fully identify problems with any properties we acquire.

We  acquired  a  portion  of  our  acreage  position  in  Pennsylvania  and  Colorado  through  property  acquisitions  and  acreage  trades,  and  we  may  acquire
additional  acreage  in  Colorado,  Pennsylvania  or  other  regions  in  the  future.  Although  we  conduct  a  review  of  properties  we  acquire  which  we  believe  is
consistent with industry practices, we can give no assurance that we have identified or will identify all existing or potential problems associated with such
properties or that we will be able to mitigate any problems we do identify.

Item 2.

Properties. 

Location and Characteristics

The  Company  owns  oil  and  natural  gas  leases  in  Wyoming  and  Pennsylvania  and  oil  and  gas  leases  and  fee  minerals  in  Colorado.  The  leases  in
Wyoming are primarily federal leases with 10-year lease terms until establishment of production. Production extends the lease terms until cessation of that
production.  In  Pennsylvania,  the  leases  are  from  private  individuals  and  companies,  as  well  as  from  the  Commonwealth  of  Pennsylvania.  The  leases  in
Pennsylvania are mostly undeveloped at this time and typically have primary lease terms of five years until establishment of production. In Colorado, our oil
and gas leases are from private individuals and companies, as well as from the State of Colorado, and typically have primary lease terms of five years. All of
our acreage in Colorado is undeveloped at this time.

Green River Basin, Wyoming

As  of  December  31,  2011,  the  Company  owned  developed  oil  and  natural  gas  leases  totaling  approximately  93,000  gross  (53,000  net)  acres  in  the
southwest  Wyoming's  Green  River  Basin.  Most  of  this  acreage  covers  Pinedale  and  Jonah  fields  in  Sublette  County,  Wyoming,  with  some  smaller
undeveloped acreage blocks located

north  and  west  of  Pinedale.  Of  the  total  acreage  position  in  Wyoming,  approximately  22,000  gross  (10,000  net)  acres  were  developed,  and  71,000  gross
(43,000 net) acres were undeveloped. The developed portion represents 31% of the Company's total developed net acreage while the undeveloped portion
represents approximately 11% of the Company's total undeveloped net acreage.

Lease maintenance costs in Wyoming were approximately $0.2 million for the year ended December 31, 2011. The Company currently owns 39 leases
totaling 74,000 gross (37,000 net) acres currently held by production and activities ("HBP") in Wyoming. The HBP acreage includes all of the Company's
leases within the productive area of the Pinedale and Jonah fields.

Development  Wells.        During  2011,  the  Company  participated  in  the  drilling  of  198  gross  (112.88  net)  productive  development  wells  on  the  Green
River Basin properties. At year end 2011, there were 35 gross (17.79 net) additional development wells that commenced during the year and were either still
drilling or had operations suspended at a depth short of total depth. 

Exploratory Wells.    During 2011, the Company participated in the drilling of a total of 2 gross (0.61 net) productive exploratory wells on the Green
River Basin properties. At December 31, 2011, there were no additional exploratory wells that commenced during the year that were either still drilling or had
operations suspended at a depth short of total depth and thus a determination of productive capability could not be made at year end.

Pennsylvania

As  of  December  31,  2011,  the  Company  owned  oil  and  gas  leases  covering  499,000  gross  (258,000  net)  acres  in  the  Pennsylvania  portion  of  the
Appalachian Basin. This acreage is located in the heart of northeast Pennsylvania's Marcellus Shale Gas Trend, principally in Potter, Tioga, Lycoming, Centre
and  Clinton  counties.  Of  the  total  acreage  position  as  of  December  31,  2011,  approximately  38,000  gross  (22,000  net)  acres  were  developed,  and
461,000 gross (236,000 net) acres were undeveloped. The developed portion represents 69% of the Company's total developed net acreage position while the
undeveloped portion represents 58% of the Company's total undeveloped net acreage position. The Company operates approximately 84,000 gross (58,000
net) acres of the total position.

Lease maintenance costs in Pennsylvania were approximately $3.3 million for the year ended December 31, 2011. The Company owns approximately

362,000 gross (185,000 net) acres currently held by production or activities in Pennsylvania.

Development Wells.    During 2011, the Company participated in the drilling of 136 gross (61.67 net) productive development wells in Pennsylvania, all
of which were horizontal wells. At year end 2011, there were 6 gross (2.10 net) additional development wells that commenced during the year and were either
still drilling or had operations suspended at a depth short of total depth.

Exploratory Wells.    During the year ended December 31, 2011, the Company participated in the drilling of a total of 49 gross (25.47 net) productive
exploratory wells on the Pennsylvania properties. Of that total, 18 gross (9.47 net) were horizontal wells and 31 gross ( 16.00 net) were vertical wells. At
December 31, 2011, there was 1 gross (0.50 net) additional exploratory well that commenced during the year that was either still drilling or had operations
suspended at a depth short of total depth and thus a determination of productive capability could not be made at year end.

Seismic  Activity.        The  Company  did  not  acquire  any  3D  seismic  data  on  its  properties  during  2011.  The  Company's  total  3D  seismic  coverage  in

Pennsylvania is 315 square miles. Of this, 285 square miles of data is owned with other parties, and 30 square miles is owned solely by the Company.

Denver Julesburg Basin, Colorado

As of December 31, 2011, the Company owned fee minerals and oil and gas leases covering 149,000 gross (130,000 net) acres in eastern Colorado's

Denver Julesburg Basin. The total acreage in Colorado represents approximately 32% of the Company's undeveloped net acreage position.

Lease maintenance costs in Colorado were immaterial for the year ended December 31, 2011. All of the Colorado acreage is undeveloped at this time;

none of it is held by production.

Exploratory Wells.    The Company did not participate in drilling any exploratory wells in Colorado during 2011.

Development Wells.    The Company did not participate in drilling any development wells in Colorado during 2011.

Seismic  Activity.        The  Company  acquired  ownership  rights  to  22  square  miles  of  3D  seismic  data  in  El  Paso  County,  Colorado  and  licensed  an

additional 126 miles of 2D data in the same county. This represents the Company's total seismic position in the area.

Oil and Gas Reserves

The following table sets forth the Company's quantities of proved reserves for the years ended December 31, 2011, 2010, and 2009 as estimated by
independent  petroleum  engineers  Netherland,  Sewell  &  Associates,  Inc.  The  table  summarizes  the  Company's  proved  reserves,  the  estimated  future  net
revenues from these reserves and the standardized measure of discounted future net cash flows attributable thereto at December 31, 2011, 2010 and 2009. As
of December 31, 2011, proved undeveloped reserves represent 58.9% of the Company's total proved reserves. The Company's proved undeveloped reserves
are limited to economic locations that are scheduled in accordance with the Company's current planning and budgeting process. The inventory of bookable
locations available to the Company is substantially larger than the amount ultimately included in the Company's year-end reserves. From time to time, the
Company may adjust the inventory and schedule of its proved undeveloped locations in response to changes in capital budget, economics, new opportunities
in the portfolio or resource availability. The Company has not scheduled any proved undeveloped reserves beyond five years nor does it have any proved
undeveloped locations that have been part of its inventory of proved undeveloped locations for over five years.

Our policies and practices regarding internal controls over the recording of reserves is structured to objectively and accurately estimate our oil and gas
reserves quantities and present values in compliance with the SEC's regulations and GAAP. The Vice President — Reservoir Engineering & Development is
primarily responsible for overseeing the preparation of the Company's reserve estimates by our independent engineers, Netherland, Sewell & Associates, Inc.
The  Vice  President  —  Reservoir  Engineering  and  Development  has  a  Bachelor  and  Master  of  Science  degree  in  Petroleum  Engineering  and  is  a  licensed
Professional Engineer with over 17 years of experience. The Company's internal controls over reserve estimates include reconciliation and review controls,
including an independent internal review of assumptions used in the estimation. Our internal professional staff works closely with our independent engineers
to  ensure  the  integrity,  accuracy  and  timeliness  of  data  that  is  furnished  to  them  for  their  reserve  estimation  process.  In  addition,  other  pertinent  data  is
provided such as seismic information, geologic maps, well logs, production tests, well performance data, operating procedures and relevant economic criteria.
We make available all information requested, including our pertinent personnel, to the external engineers as part of their evaluation of our reserves.

All  of  the  information  regarding  reserves  in  this  annual  report  is  derived  from  the  report  of  Netherland,  Sewell  &  Associates,  Inc.  The  report  of
Netherland,  Sewell  &  Associates,  Inc.  is  included  as  an  Exhibit  to  this  annual  report.  The  principal  engineer  at  Netherland,  Sewell  &  Associates,  Inc.
responsible for preparing our

Table of Contents

reserve  estimates  has  a  Bachelor  of  Science  degree  in  Mechanical  Engineering  and  is  a  licensed  Professional  Engineer  with  over  25  years  of  experience,
including significant experience throughout the Rocky Mountain basins.

In  estimating  proved  reserves  and  future  net  revenue  as  of  December  31,  2011,  the  Company's  independent  reserve  engineer,  Netherland,  Sewell  &
Associates,  Inc.,  used  technical  and  economic  data  including,  but  not  limited  to,  well  logs,  geologic  maps,  seismic  data,  well  test  data,  production  data,
historical  price  and  cost  information  and  property  ownership  interests.  The  reserves  were  estimated  using  deterministic  methods;  these  estimates  were
prepared  in  accordance  with  generally  accepted  petroleum  engineering  and  evaluation  principles.  Standard  engineering  and  geoscience  methods,  such  as
performance  analysis,  volumetric  analysis  and  analogy,  that  were  considered  to  be  appropriate  and  necessary  to  establish  reserve  quantities  and  reserve
categorization that conform to SEC definitions and rules and regulations, were also used. In evaluating the information at their disposal, Netherland, Sewell &
Associates, Inc. excluded from their consideration all matters as to which the controlling interpretation may be legal or accounting, rather than engineering
and geoscience. As in all aspects of oil and natural gas evaluation, there are uncertainties inherent in the interpretation of engineering and geoscience data;
therefore, Netherland, Sewell & Associates, Inc.'s conclusions necessarily represent only informed professional judgment.

As a result of Ultra's drilling activities in 2011, 330.3 Bcfe (13%) of reserves classified as proved undeveloped at January 1, 2011 were converted into
proved developed reserves. Proved undeveloped reserves increased as a result of ongoing drilling and development activities. The Company did not have any
material changes to proved undeveloped volumes due to revisions during the year ended December 31, 2011.

(1) Oil and condensate are converted to natural gas at the ratio of one barrel of oil or condensate to six Mcf of natural gas. This conversion ratio, which is
typically used in the oil and gas industry, represents the approximate energy equivalent of a barrel of oil or condensate to an Mcf of natural gas. The
sales price of one barrel of oil or condensate has been much higher than the sales price of six Mcf of natural gas over the last several years, so a six to
one conversion ratio does not represent the economic equivalency of six Mcf of natural gas to one barrel of oil or condensate.

(2) Management believes that the presentation of the standardized measure of discounted future net cash flows, before income taxes, of estimated proved
reserves, discounted at 10% per annum, may be considered a non-Generally Accepted Accounting Principle financial measure as defined in Item 10(e)

Regulation S-K, therefore the Company has included this reconciliation of the measure to the most directly comparable Generally Accepted Accounting
Principle ("GAAP") financial measure (standardized measure of discounted future net cash flows, after income taxes). Management believes that the
presentation of the standardized measure of future net cash flows before income taxes provides useful information to investors because it is widely used
by  professional  analysts  and  sophisticated  investors  in  evaluating  oil  and  gas  companies.  Because  many  factors  that  are  unique  to  each  individual
company  may  impact  the  amount  of  future  income  taxes  to  be  paid,  the  use  of  the  pre-tax  measure  provides  greater  comparability  when  evaluating
companies.  It  is  relevant  and  useful  to  investors  for  evaluating  the  relative  monetary  significance  of  the  Company's  oil  and  natural  gas  properties.
Further, investors may utilize the measure as a basis for comparison of the relative size and value of the Company's reserves to other companies. The
standardized measure of discounted future net cash flows, before income taxes, is not a measure of financial or operating performance under GAAP,
nor is it intended to represent the current market value of the estimated oil and natural gas reserves owned by the Company. Standardized measure of
discounted  future  net  cash  flows,  before  income  taxes,  should  not  be  considered  in  isolation  or  as  a  substitute  for  the  standardized  measure  of
discounted future net cash flows as defined under GAAP.

Reserves estimated by our independent engineers at December 31, 2011, 2010 and 2009, reflect oil and natural gas spot prices based on the average
prices during the 12-month period before the ending date of the period covered by this report determined as an unweighted, arithmetic average of the
first-day-of-the-month price for each month within such period.

Since January 1, 2011, no crude oil or natural gas reserve information has been filed with, or included in any report to, any federal authority or agency
other  than  the  SEC  and  the  Energy  Information  Administration  ("EIA")  of  the  U.S.  Department  of  Energy.  We  file  Form  23,  including  reserve  and  other
information, with the EIA.

Delivery Commitments

With respect to the Company's natural gas production, from time to time the Company enters into transactions to deliver specified quantities of gas to
its customers. As of February 16, 2012, the Company had long-term natural gas delivery commitments of 2.6 MMMBtu in 2012, 9.9 MMMBtu in 2013 and
1.8  MMMBtu  in  2014  under  existing  agreements.  None  of  these  commitments  require  the  Company  to  deliver  gas  produced  specifically  from  any  of  the
Company's  properties,  and  all  of  these  commitments  are  priced  on  a  floating  basis  with  reference  to  an  index  price.  These  amounts  are  well  below  the
Company's forecasted 2012 and anticipated 2013 and 2014 production from its available reserves. In addition, none of the Company's reserves are subject to
any  priorities  or  curtailments  that  may  affect  quantities  delivered  to  its  customers,  any  priority  allocations  or  price  limitations  imposed  by  federal  or  state
regulatory agencies or any other factors beyond the Company's control that may affect its ability to meet its contractual obligations other than those discussed
in Item 1A. "Risk Factors". The Company believes that its production and reserves are adequate to meet its delivery commitments. If for some reason the
Company's production is not sufficient to satisfy its delivery commitments, the Company expects to be able to purchase natural gas production in the market
to satisfy its commitments.

With respect to the Company's oil production, the Company does not have any long-term arrangements that commit the Company to deliver a fixed or

determinable quantity of oil in the near future.

Productive Wells

As of December 31, 2011 the Company's total gross and net wells were as follows:

Productive Wells*
Natural Gas and Condensate

Gross Wells

Net Wells

2,137.0  

1,063.5  

* Productive wells are producing wells, shut-in wells the Company deems capable of production, wells that are waiting for completion, plus wells that are
drilled/cased  and  completed,  but  waiting  for  pipeline  hook-up.  A  gross  well  is  a  well  in  which  a  working  interest  is  owned.  The  number  of  net  wells
represents the sum of fractional working interests the company owns in gross wells.

Oil and Gas Acreage

The primary terms of the Company's oil and gas leases expire at various dates. Much of the Company's undeveloped acreage is held by production,
which  means  that  the  Company  will  maintain  its  rights  in  these  leases  as  long  as  oil  or  natural  gas  is  produced  from  the  acreage  by  it  or  by  other  parties
holding interests in producing wells on those leases. In some cases, if production from a lease ceases, the lease will expire, and in some cases, if production
from a lease ceases, the Company may maintain the lease by additional operations on the acreage.

The  Company  does  not  believe  the  remaining  terms  of  its  leases  is  material.  At  December  31,  2011,  the  Company  had  5,300  net  acres  of  leases  in
Pennsylvania,  700  net  acres  of  leases  in  Wyoming  and  no  leases  in  Colorado  that  expire  in  2012  and  it  expects  to  maintain  over  90%  of  those  leases  by
production,  operations,  extensions  or  renewals.  The  Company  does  not  expect  to  lose  material  lease  acreage  because  of  failure  to  drill  due  to  inadequate
capital, equipment or personnel. The Company has, based on its evaluation of prospective economics, allowed acreage to expire and it may allow additional
acreage to expire in the future.

Item 7. — Management's Discussion and Analysis of Financial Condition and Results of Operations 

The following discussion of the financial condition and operating results of the Company should be read in conjunction with the consolidated financial
statements and related notes of the Company, which are included in this report in Item 8, and the information set forth in Risk Factors under Item 1A. Except
as otherwise indicated, all amounts are expressed in U.S. dollars.

Overview

Ultra  Petroleum  Corp.  is  an  independent  exploration  and  production  company  focused  on  developing  its  long-life  natural  gas  reserves  in  the  Green
River  Basin  of  Wyoming  —  the  Pinedale  and  Jonah  fields  —  and  is  in  the  early  exploration  and  development  stages  in  the  Appalachian  Basin  of
Pennsylvania. In addition, the Company has recently acquired acreage in eastern Colorado's Denver Julesburg Basin. The Company operates in one industry
segment, natural gas and oil exploration and development, with one geographical segment, the United States.

The Company currently conducts operations exclusively in the United States. Substantially all of its oil and natural gas activities are conducted jointly
with others and, accordingly, amounts presented reflect only the Company's proportionate interest in such activities. Inflation has not had a material impact on
the Company's results of operations. The Company continues to focus on improving its drilling and production results through gaining efficiencies with the
use of advanced technologies, detailed technical analysis of its properties and leveraging its experience into improved operational efficiencies. Inflation is not
expected to have a material impact on the Company's results of operations in the future.

The Company currently generates its revenue, earnings and cash flow primarily from the production and sales of natural gas and condensate from its
property in southwest Wyoming with an increasing portion of the Company's revenues coming from gas sales from wells located in the Appalachian Basin in
Pennsylvania.

The  price  of  natural  gas  is  a  critical  factor  to  the  Company's  business  and  the  price  of  natural  gas  has  historically  been  volatile.  Volatility  could  be
detrimental to the Company's financial performance. The Company seeks to limit the impact of this volatility on its results by entering into swap agreements
and/or fixed price forward physical delivery contracts for natural gas. The average price realization for the Company's natural gas during 2011 was $5.05 per
Mcf,  including  realized  gains  and  losses  on  commodity  derivatives.  During  the  quarter  ended  December  31,  2011,  the  average  price  realization  for  the
Company's natural gas was $4.77 per Mcf, including realized gains and losses on commodity derivatives. The Company's average price realization for natural
gas, excluding realized gains and losses on commodity derivatives, was $4.15 per Mcf and $3.69 per Mcf for the year and quarter ended December 31, 2011,
respectively. (See Note 8).

Mission and Strategy

Ultra's mission is to profitably grow an upstream oil and gas company for the long-term benefit of its shareholders. Ultra's strategy includes building a
robust portfolio of high return investment opportunities, maintaining a disciplined approach to capital investment, maximizing earnings and cash flows by
controlling costs and maintaining financial flexibility.

High Return Portfolio.    Ultra seeks to maintain a portfolio of properties that provide long-term, profitable growth through development in areas that
support sustainable, lower-risk, repeatable, high return drilling projects. The Company continually evaluates opportunities for the acquisition, exploration and
development of additional oil and natural gas properties that afford risk-adjusted returns in excess of or equal to its current set of investment alternatives.

Disciplined  Capital  Investment.        The  Company's  business  strategy  involves  the  regular  review  of  its  investment  opportunities  in  order  to  optimize

return to its shareholders. Over the past twelve years, Ultra has consistently delivered meaningful reserve and production growth.

Low Cost Producer.    Ultra strives to maintain one of the lowest cost structures in the industry in terms of both adding and producing oil and natural
gas  reserves.  The  Company  continues  to  focus  on  improving  its  drilling  and  production  results  through  the  use  of  advanced  technologies  and  detailed
technical analysis of its properties.

Financial Flexibility.    Preserving financial flexibility and a strong balance sheet are also strategic to Ultra's business philosophy. Maintaining financial

discipline enables the Company to capitalize on the flexibility of its portfolio.

2011 Operating Highlights

The Company has consistently delivered meaningful reserve and production growth over the past ten years and management believes it has the ability

to continue growing production by drilling already identified locations on its core properties. Highlights for 2011 include:

•   Achieved production of 245.3 Bcfe, a 15% increase as compared to 2010;
•   Proved reserves increased 13% to 5.0 Tcfe from 4.4 Tcfe in 2010;
•   Finding and development costs of $1.60 per Mcfe as compared to $1.48 per Mcfe in 2010;
•   Reserve replacement ratio of 339% as compared to 324% in 2010;
•   Reduced average drilling time to 12 days per well in Wyoming, spud to total depth, a 14% reduction from 2010;
•   95% of wells drilled in Wyoming in less than 15 days as compared to 76% in 2010;
•   Initiated production from 112 gross (59 net) horizontal wells in Pennsylvania;
•   All-in costs of $2.88 per Mcfe;
•   Acquired 149,000 gross (130,000 net) acres targeting the Niobrara formation in the Denver Julesburg Basin in eastern Colorado, and

Critical Accounting Policies

The discussion and analysis of the Company's financial condition and results of operations is based upon consolidated financial statements, which have
been  prepared  in  accordance  with  U.S.  GAAP.  In  addition,  application  of  GAAP  requires  the  use  of  estimates,  judgments  and  assumptions  that  affect  the
reported amounts of assets and liabilities as of the date of the financial statements as well as the revenues and expenses reported during the period. Changes in
these  estimates  related  to  judgments  and  assumptions  will  occur  as  a  result  of  future  events,  and,  accordingly,  actual  results  could  differ  from  amounts
estimated. Set forth below is a discussion of the critical accounting policies used in the preparation of our financial statements which we believe involve the
most complex or subjective decisions or assessments.

Oil  and  Gas  Reserves.        The  reserve  estimates  presented  herein  were  made  in  accordance  with  oil  and  gas  reserve  estimation  and  disclosure
authoritative accounting guidance according to FASB ASC 932 as updated in order to align the reserve calculation and disclosure requirements with those in
SEC Release No. 33-8995.

The Company's proved undeveloped reserves are limited to economic locations that are scheduled in accordance with the Company's current planning
and  budgeting  process.  The  inventory  of  bookable  locations  available  to  the  Company  is  substantially  larger  than  the  amount  ultimately  included  in  the
Company's  year-end  reserves.  From  time  to  time,  the  Company  may  adjust  the  inventory  and  schedule  of  its  proved  undeveloped  locations  in  response  to
changes in capital budget, economics, new opportunities in the portfolio or resource availability. The Company has not scheduled any proved undeveloped
reserves beyond five years nor does it have any proved undeveloped locations that have been part of its inventory of proved undeveloped locations for over
five years.

The Company utilizes reliable technology such as seismic data and interpretation, wireline formation tests, geophysical logs and core data to assess its
resources. However, none of these technologies have contributed to a material addition to the proved reserves in this report. The proved reserves estimates are
prepared by Netherland, Sewell & Associates, Inc., an independent, third-party engineering firm.

Estimates of proved crude oil and natural gas reserves significantly affect the Company's depreciation, depletion and amortization ("DD&A") expense.
For example, if estimates of proved reserves decline, the Company's DD&A rate will increase, resulting in a decrease in net income. A decline in estimates of
proved reserves may result from a number of factors including lower prices, evaluation of additional operating history, mechanical problems on our wells and
catastrophic events. Lower prices also make it uneconomical to drill wells or produce from fields with high operating costs.

The Company's proved reserves are a function of many assumptions, all of which could deviate materially from actual results. As a result, the estimates

of proved reserves could vary over time, and could vary from actual results.

Full  Cost  Method  of  Accounting.        The  accounting  for  and  disclosure  of  oil  and  gas  producing  activities  requires  that  we  choose  between  GAAP
alternatives.  The  Company  uses  the  full  cost  method  of  accounting  for  its  oil  and  natural  gas  operations.  Under  this  method,  separate  cost  centers  are
maintained for each country in which the Company incurs costs. All costs incurred in the acquisition, exploration and development of properties (including
costs of surrendered and abandoned leaseholds, delay lease rentals, dry holes and overhead related to exploration and development activities) are capitalized.
The sum of net capitalized costs and estimated future development costs of oil and natural gas properties for each full cost center are depleted using the units-
of-production method. Changes in estimates of proved reserves, future development costs or asset retirement obligations are accounted for prospectively in
our depletion calculation.

Under  the  full  cost  method,  costs  of  unevaluated  properties  and  major  development  projects  expected  to  require  significant  future  costs  may  be

excluded from capitalized costs being amortized. The Company excludes

40

 
 
Table of Contents

significant  costs  until  proved  reserves  are  found  or  until  it  is  determined  that  the  costs  are  impaired.  Excluded  costs,  if  any,  are  reviewed  quarterly  to
determine if impairment has occurred. The amount of any impairment is transferred to the capitalized costs being amortized in the appropriate full cost pool.

Companies that use the full cost method of accounting for oil and natural gas exploration and development activities are required to perform a ceiling
test  calculation  each  quarter.  The  full  cost  ceiling  test  is  an  impairment  test  prescribed  by  SEC  Regulation  S-X  Rule  4-10.  The  ceiling  test  is  performed
quarterly, on a country-by-country basis, utilizing the average of prices in effect on the first day of the month for the preceding twelve month period. The
ceiling limits such pooled costs to the aggregate of the present value of future net revenues attributable to proved crude oil and natural gas reserves discounted
at 10% plus the lower of cost or market value of unproved properties less any associated tax effects. If such capitalized costs exceed the ceiling, the Company
will record a write-down to the extent of such excess as a non-cash charge to earnings. Any such write-down will reduce earnings in the period of occurrence
and result in lower DD&A expense in future periods. A write-down may not be reversed in future periods even though higher oil and natural gas prices may
subsequently increase the ceiling.

During  the  first  quarter  of  2009,  the  Company  recorded  a  $1.0  billion  ($673.0  million  net  of  tax)  non-cash  write-down  of  the  carrying  value  of  the
Company's proved oil and gas properties as of March 31, 2009, as a result of the ceiling test limitation, which is reflected as write-down of proved oil and gas
properties in the accompanying consolidated statements of operations. The Company did not have any write-downs related to the full cost ceiling limitation in
2011 or 2010.

Asset Retirement Obligation.    The Company's asset retirement obligations ("ARO") consist primarily of estimated costs of dismantlement, removal,
site  reclamation  and  similar  activities  associated  with  its  oil  and  natural  gas  properties.  FASB  ASC  Topic  410,  Asset  Retirement  and  Environmental
Obligations ("FASB ASC 410") requires that the discounted fair value of a liability for an ARO be recognized in the period in which it is incurred with the
associated asset retirement cost capitalized as part of the carrying cost of the oil and natural gas asset. The recognition of an ARO requires that management
make  numerous  estimates,  assumptions  and  judgments  regarding  such  factors  as  the  existence  of  a  legal  obligation  for  an  ARO,  estimated  probabilities,
amounts and timing of settlements; the credit-adjusted, risk-free rate to be used; inflation rates, and future advances in technology. In periods subsequent to
initial measurement of the ARO, the Company must recognize period-to-period changes in the liability resulting from the passage of time and revisions to
either the timing or the amount of the original estimate of undiscounted cash flows. Increases in the ARO liability due to passage of time impact net income as
accretion expense. The related capitalized costs, including revisions thereto, are charged to expense through DD&A.

Entitlements Method of Accounting for Oil and Natural Gas Sales.    The Company generally sells natural gas and condensate under both long-term and
short-term  agreements  at  prevailing  market  prices  and  under  multi-year  contracts  that  provide  for  a  fixed  price  of  oil  and  natural  gas.  The  Company
recognizes  revenues  when  the  oil  and  natural  gas  is  delivered,  which  occurs  when  the  customer  has  taken  title  and  has  assumed  the  risks  and  rewards  of
ownership,  prices  are  fixed  or  determinable  and  collectability  is  reasonably  assured.  The  Company  accounts  for  oil  and  natural  gas  sales  using  the
"entitlements  method."  Under  the  entitlements  method,  revenue  is  recorded  based  upon  the  Company's  ownership  share  of  volumes  sold,  regardless  of
whether it has taken its ownership share of such volumes. The Company records a receivable or a liability to the extent it receives less or more than its share
of the volumes and related revenue.

Make-up provisions and ultimate settlements of volume imbalances are generally governed by agreements between the Company and its partners with
respect to specific properties or, in the absence of such agreements, through negotiation. The value of volumes over- or under-produced can change based on
changes in commodity prices. The Company prefers the entitlements method of accounting for oil and natural gas sales because it allows for recognition of
revenue based on its actual share of jointly owned production, results in better matching of revenue with related operating expenses, and provides balance
sheet recognition of the estimated value of product imbalances.

Valuation of Deferred Tax Assets.    The Company uses the asset and liability method of accounting for income taxes. Under this method, future income
tax assets and liabilities are determined based on differences between the financial statement carrying values and their respective income tax basis (temporary
differences).

To assess the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax
assets  will  not  be  realized.  The  ultimate  realization  of  deferred  tax  assets  is  dependent  upon  the  generation  of  future  taxable  income  during  the  periods  in
which  those  temporary  differences  become  deductible.  Management  considers  the  scheduled  reversal  of  deferred  tax  liabilities,  projected  future  taxable
income and tax planning strategies in making this assessment.

Derivative Instruments and Hedging Activities.    Currently, the Company largely relies on commodity derivative contracts (generally, financial swaps)
to manage its exposure to commodity price risk. Additionally, and from time to time, the Company enters into physical, fixed price forward natural gas sales
in order to mitigate its commodity price exposure on a portion of its natural gas production. These fixed price forward gas sales are considered normal sales in
the ordinary course of business and outside the scope of FASB ASC Topic 815, Derivatives and Hedging ("FASB ASC 815").

Effective  November  3,  2008,  the  Company  changed  its  method  of  accounting  for  natural  gas  commodity  derivatives  to  reflect  unrealized  gains  and
losses on commodity derivative contracts in the income statement rather than on the balance sheet. The Company previously followed hedge accounting for
its natural gas hedges. Under this prior accounting method, the unrealized gain or loss on qualifying cash flow hedges (calculated on a mark to market basis,
net of tax) was recorded on the balance sheet in stockholders' equity as accumulated other comprehensive income (loss). When an unrealized hedging gain or
loss was realized upon contract expiration, it was reclassified into earnings through inclusion in natural gas sales revenues. The Company continues to record
the  fair  value  of  its  commodity  derivatives  as  an  asset  or  liability  on  the  Consolidated  Balance  Sheets,  but  records  the  changes  in  the  fair  value  of  its
commodity derivatives in the Consolidated Statements of Operations as an unrealized gain or loss on commodity derivatives. There was no resulting effect on
overall cash flow, total assets, total liabilities or total stockholders' equity.

Fair Value Measurements.    The Company follows FASB ASC Topic 820, Fair Value Measurements and Disclosures ("FASB ASC 820. Under FASB
ASC  820,  fair  value  is  defined  as  the  price  that  would  be  received  to  sell  an  asset  or  paid  to  transfer  a  liability  in  an  orderly  transaction  between  market
participants at measurement date and establishes a three level hierarchy for measuring fair value. The valuation assumptions utilized to measure the fair value
of the Company's commodity derivatives were observable inputs based on market data obtained from independent sources and are considered Level 2 inputs
(quoted prices for similar assets, liabilities (adjusted) and market-corroborated inputs). See Note 9 for additional information.

In  consideration  of  counterparty  credit  risk,  the  Company  assessed  the  possibility  of  whether  each  counterparty  to  the  derivative  would  default  by
failing  to  make  any  contractually  required  payments  as  scheduled  in  the  derivative  instrument  in  determining  the  fair  value.  Additionally,  the  Company
considers that it is of substantial credit quality and has the financial resources and willingness to meet its potential repayment obligations associated with the
derivative transactions.

The fair values summarized below were determined in accordance with the requirements of FASB ASC 820 and we aligned the categories below with
the Level 1, 2, and 3 fair value measurements as defined by FASB ASC 820. The balance of net unrealized gains and losses recognized for our energy-related
derivative instruments at December 31, 2011 is summarized in the following table based on the inputs used to determine fair value:

(b) Values with inputs that are observable directly or indirectly for the instrument, but do not qualify for Level 1.
(c) Values with a significant amount of inputs that are not observable for the instrument.

Legal, Environmental and Other Contingencies.    A provision for legal, environmental and other contingencies is charged to expense when the loss is
probable and the cost can be reasonably estimated. Determining when expenses should be recorded for these contingencies and the appropriate amounts for
accrual  is  a  complex  estimation  process  that  includes  the  subjective  judgment  of  management.  In  many  cases,  management's  judgment  is  based  on
interpretation of laws and regulations, which can be interpreted differently by regulators and/or courts of law. The Company's management closely monitors
known and potential legal, environmental and other contingencies and periodically determines when the Company should record losses for these items based
on information available to the Company.

Share-Based  Payment  Arrangements.        The  Company  follows  FASB  ASC  Topic  718,  Compensation  —  Stock  Compensation  ("FASB  ASC  718")
which requires the measurement and recognition of compensation expense for all share-based payment awards made to employees and directors, including
employee  stock  options,  based  on  estimated  fair  values.  Share-based  compensation  expense  recognized  under  FASB  ASC  718  for  the  years  ended
December 31, 2011, 2010 and 2009 was $13.9 million, $12.9 million and $10.9 million, respectively. See Note 7 for additional information.

Recent  accounting  pronouncements.        In  May  2011,  the  FASB  issued  ASU  No.  2011-04,  which  amends  FASB  ASC  820.  The  amended  guidance
clarifies  many  requirements  in  U.S.  GAAP  for  measuring  fair  value  and  for  disclosing  information  about  fair  value  measurements.  Additionally,  the
amendments clarify the FASB's intent about the application of existing fair value measurement requirements. The guidance provided in ASU No. 2011-04 is
effective for interim and annual periods beginning after December 15, 2011. The Company does not expect the adoption of this amendment to have a material
impact on its consolidated financial statements.

Results of Operations — Year Ended December 31, 2011 vs. Year Ended December 31, 2010

During the year ended December 31, 2011, production increased on a gas equivalent basis to 245.3 Bcfe from 213.6 Bcfe for the same period in 2010
attributable  to  the  Company's  successful  drilling  activities  during  2011.  Realized  natural  gas  prices,  including  realized  gain  and  loss  on  commodity
derivatives,  increased  to  $5.05  per  Mcf  during  the  year  ended  December  31,  2011  as  compared  to  $4.88  per  Mcf  during  2010.  During  the  year  ended
December  31,  2011,  the  Company's  average  price  for  natural  gas  was  $4.15  per  Mcf,  excluding  realized  gains  and  losses  on  commodity  derivatives  as
compared  to  $4.31  per  Mcf  for  the  same  period  in  2010.  The  increase  in  production  largely  contributed  to  a  12%  increase  in  revenues  for  the  year  ended
December 31, 2011 to $1.1 billion as compared to $979.4 million in 2010.

Lease operating expenses ("LOE") increased to $51.8 million for the year ended December 31, 2011 compared to $45.9 million during the same period
in 2010 due primarily to increased well counts resulting from the Company's drilling program. On a unit of production basis, LOE costs decreased to $0.21
per Mcfe at December 31, 2011 compared to $0.22 per Mcfe at December 31, 2010 as a result of increased production volumes.

During the year ended December 31, 2011, production taxes were $97.1 million compared to $95.9 million during the same period in 2010, or $0.40 per
Mcfe, compared to $0.45 per Mcfe. Production taxes are calculated based on a percentage of revenue from production in Wyoming after certain deductions
and were 8.8% of revenues for the year ended 2011 and 9.8% for the same period in 2010. The decrease in per unit taxes is primarily attributable to increased
production in Pennsylvania, which is not subject to production taxes, as well as the decrease in average natural gas prices, excluding the effects of commodity
derivatives, during the year ended December 31, 2011 as compared to the same period in 2010.

Gathering fees increased to $56.5 million for the year ended December 31, 2011 compared to $50.1 million during the same period in 2010 largely due

to increased production volumes. On a per unit basis, gathering fees remained flat at $0.23 per Mcfe for the years ended December 31, 2011 and 2010.

To  secure  pipeline  infrastructure  providing  sufficient  capacity  to  transport  a  portion  of  the  Company's  natural  gas  production  away  from  southwest
Wyoming and to provide for reasonable basis differentials for its natural gas, the Company incurred firm transportation charges totaling $64.2 million for the
period ended December 31, 2011 as compared to $65.0 million for the same period in 2010 in association with REX Pipeline transportation charges. On a per
unit basis, transportation charges decreased to $0.26 per Mcfe (on total company volumes) for the period ended December 31, 2011 as compared to $0.30 for
the same period in 2010 due to the increase in total company production volumes during the period ended December 31, 2011.

DD&A  increased  to  $346.4  million  during  the  period  ended  December  31,  2011  from  $241.8  million  for  the  same  period  in  2010,  attributable  to
increased production volumes and a higher depletion rate. On a unit of production basis, DD&A increased to $1.41 per Mcfe at December 31, 2011 from
$1.13 at December 31, 2010 largely as a result of increased well costs in Pennsylvania.

General and administrative expenses increased to $26.0 million for the period ended December 31, 2011 compared to $24.4 million for the same period
in 2010. The increase in general and administrative expenses is primarily attributable to increased headcount and related compensation. On a per unit basis,
general and administrative expenses remained flat at $0.11 per Mcfe for the years ended December 31, 2011 and 2010.

Interest expense increased to $63.2 million during the period ended December 31, 2011 compared to $49.0 million during the same period in 2010 as a
result  of  increased  borrowings  outstanding  during  the  period  ended  December  31,  2011.  For  the  years  ended  December  31,  2011  and  2010,  the  Company
capitalized $30.7 million and $21.2 million, respectively, in interest associated with unevaluated oil and gas properties that are excluded from amortization
and actively being evaluated as well as work in process relating to gathering systems that are not currently in service. At December 31, 2011, the Company
had $1.9 billion in borrowings outstanding.

During the year ended December 31, 2010, the Company recognized litigation expenses of $9.9 million related to the resolution of litigation matters.

During the year ended December 31, 2011, the Company recognized $213.3 million related to realized gain on commodity derivatives as compared to
$116.8 million during the year ended December 31, 2010. The realized gain or loss on commodity derivatives relates to actual amounts received or paid under
the Company's derivative contracts.

At December 31, 2011, the Company recognized $100.4 million related to unrealized gain on commodity derivatives as compared to $208.6 million
related to unrealized gain on commodity derivatives at December 31, 2010. The unrealized gain or loss on commodity derivatives represents the non-cash
change in the fair value of these derivative instruments.

The Company recognized income before income taxes of $710.9 million for the year ended December 31, 2011 compared with $723.1 million for the
same period in 2010. The decrease in earnings is primarily a result of increased DD&A expense during 2011 and partially offset by increased revenues during
2011.

The  income  tax  provision  recognized  for  the  year  ended  December  31,  2011  was  $257.7  million  compared  with  an  income  tax  provision  of

$258.6 million for the year ended December 31, 2010.

For the year ended December 31, 2011, the Company recognized net income of $453.2 million or $2.94 per diluted share as compared with net income
of $464.5 million or $3.01 per diluted share for the same period in 2010. The decrease is primarily attributable to increased DD&A expense during 2011 and
partially offset by increased revenues during 2011.

Results of Operations — Year Ended December 31, 2010 vs. Year Ended December 31, 2009

During the year ended December 31, 2010, production increased on a gas equivalent basis to 213.6 Bcfe from 180.1 Bcfe for the same period in 2009
attributable  to  the  Company's  successful  drilling  activities  during  2010.  Realized  natural  gas  prices,  including  realized  gain  and  loss  on  commodity
derivatives, remained flat at $4.88 per Mcf during the years ended December 31, 2010 and 2009. During the year ended December 31, 2010, the Company's
average price for natural gas was $4.31 per Mcf, excluding realized gains and losses on commodity derivatives as compared to $3.49 per Mcf for the same
period in 2009. The increase in production contributed to a 47% increase in revenues for the year ended December 31, 2010 to $979.4 million as compared to
$666.8 million in 2009.

LOE  increased  to  $45.9  million  for  the  year  ended  December  31,  2010  compared  to  $40.7  million  during  the  same  period  in  2009  due  primarily  to
increased well counts resulting from the Company's drilling program. On a unit of production basis, LOE costs decreased to $0.22 per Mcfe at December 31,
2010 compared to $0.23 per Mcfe at December 31, 2009 as a result of increased production volumes.

During the year ended December 31, 2010, production taxes were $95.9 million compared to $67.0 million during the same period in 2009, or $0.45 per
Mcfe, compared to $0.37 per Mcfe. The increase in per unit taxes is attributable to increased sales revenues as a result of higher realized gas prices (excluding
realized gain on commodity derivatives) during the year ended December 31, 2010 as compared to the same period in 2009. Production taxes are calculated
based on a percentage of revenue from production and were 9.8% of revenues for the year ended 2010 and 10.0% for the same period in 2009.

Gathering fees increased to $50.1 million for the year ended December 31, 2010 compared to $45.2 million during the same period in 2009 largely due
to increased production volumes. On a per unit basis, gathering fees decreased to $0.23 per Mcfe for the year ended December 31, 2010 as compared to $0.25
per Mcfe for the same period in 2009.

To  secure  pipeline  infrastructure  providing  sufficient  capacity  to  transport  a  portion  of  the  Company's  natural  gas  production  away  from  southwest
Wyoming and to provide for reasonable basis differentials for its natural gas, the Company incurred firm transportation charges totaling $65.0 million for the
period ended December 31, 2010 as compared to $58.0 million for the same period in 2009 in association with REX Pipeline transportation charges. On a per
unit basis, transportation charges decreased to $0.30 per Mcfe (on total company volumes) for the period ended December 31, 2010 as compared to $0.32 for
the same period in 2009 due to the increase in total company production volumes during the period ended December 31, 2010 and partially offset by increased
transportation rates as a result of further eastern expansion of REX.

DD&A  increased  to  $241.8  million  during  the  period  ended  December  31,  2010  from  $201.8  million  for  the  same  period  in  2009,  attributable  to

increased production volumes. On a unit of production basis, DD&A increased to $1.13 per Mcfe at December 31, 2010 from $1.12 at December 31, 2009.

General and administrative expenses increased to $24.4 million for the period ended December 31, 2010 compared to $19.8 million for the same period
in 2009. The increase in general and administrative expenses is primarily attributable to increased headcount and related compensation. On a per unit basis,
general and administrative expenses remained flat at $0.11 per Mcfe for the years ended December 31, 2010 and 2009.

Interest expense increased to $49.0 million during the period ended December 31, 2010 compared to $37.2 million during the same period in 2009 as a
result of increased borrowings during the period ended December 31, 2010. For the year ended December 31, 2010, the Company capitalized $21.2 million in
interest associated with unevaluated oil and gas properties that are excluded from amortization and actively being evaluated as well as work in process relating
to gathering systems that are not currently in service. There was no interest capitalized during the year ended December 31, 2009. At December 31, 2010, the
Company had $1.6 billion in borrowings outstanding.

Other expense for the year ended December 31, 2009 includes rig termination payments of $2.9 million that were not incurred during 2010.

During the year ended December 31, 2010, the Company recognized litigation expenses of $9.9 million related to the resolution of litigation matters.

During the year ended December 31, 2010, the Company recognized $116.8 million related to realized gain on commodity derivatives as compared to
$239.4 million during the year ended December 31, 2009. The realized gain or loss on commodity derivatives relates to actual amounts received or paid under
the Company's derivative contracts.

At  December  31,  2010,  the  Company  recognized  $208.6  million  related  to  unrealized  gain  on  commodity  derivatives  as  compared  to  $92.8  million
related to unrealized loss on commodity derivatives at December 31, 2009. The unrealized gain or loss on commodity derivatives represents the change in the
fair value of these derivative instruments.

The Company recognized income before income taxes of $723.1 million for the year ended December 31, 2010 compared with a loss of $696.2 million
for the same period in 2009. The increase in earnings is primarily a result of the non-cash write-down of oil and gas properties associated with the ceiling test
limitation  during  the  first  quarter  of  2009,  increased  production  during  2010  and  unrealized  gains  on  commodity  derivatives  during  the  period  ended
December 31, 2010 as compared to the same period in 2009.

The income tax provision recognized for the year ended December 31, 2010 was $258.6 million compared with an income tax benefit of $245.1 million
for the year ended December 31, 2009 due to a net loss during the year ended December 31, 2009 primarily as a result of the non-cash write-down of oil and
gas properties associated with the ceiling test limitation.

For the year ended December 31, 2010, the Company recognized net income of $464.5 million or $3.01 per diluted share as compared with a net loss of
$451.1  million  or  ($2.98)  per  diluted  share  for  the  same  period  in  2009.  The  increase  is  primarily  attributable  to  the  non-cash  write-down  of  oil  and  gas
properties associated with the ceiling test limitation during the first quarter of 2009, increased production during 2010 and unrealized gains on commodity
derivatives during the year ended December 31, 2010 as compared to the same period in 2009.

The discussion and analysis of the Company's financial condition and results of operations is based upon consolidated financial statements, which have
been prepared in accordance with U.S. GAAP. In addition, application of generally accepted accounting principles requires the use of estimates, judgments
and  assumptions  that  affect  the  reported  amounts  of  assets  and  liabilities  as  of  the  date  of  the  financial  statements  as  well  as  the  revenues  and  expenses
reported  during  the  period.  Changes  in  these  estimates,  judgments  and  assumptions  will  occur  as  a  result  of  future  events,  and,  accordingly,  actual  results
could differ from amounts estimated.

LIQUIDITY AND CAPITAL RESOURCES

During the year ended December 31, 2011, the Company relied on cash provided by operations along with borrowings under its senior credit facility to
finance its capital expenditures. The Company participated in 385 wells that were drilled to total depth in Wyoming and Pennsylvania during 2011. For the
year ended December 31, 2011, total capital expenditures were $1.54 billion ($1.43 billion related to oil and gas exploration and development expenditures,
$84.0 million related to gathering system expenditures and $21.9 million related to land and other property costs).

At  December  31,  2011,  the  Company  reported  a  cash  position  of  $11.3  million  compared  to  $70.8  million  at  December  31,  2010.  Working  capital
deficit at December 31, 2011 was $251.1 million compared to a deficit of $57.0 million at December 31, 2010. At December 31, 2011, the Company had
$343.0 million in outstanding

46

 
 
Table of Contents

borrowings  under  the  bank  credit  facility  and  $657.0  million  of  available  borrowing  capacity  under  the  credit  facility.  In  addition,  the  Company  had
$1.6 billion outstanding in senior notes (See Note 6). Other long-term obligations of $67.0 million at December 31, 2011 is comprised of items payable in
more than one year, primarily related to production taxes and asset retirement obligations.

The Company's positive cash provided by operating activities, along with availability under the senior credit facility, are projected to be sufficient to
fund the Company's budgeted capital investment program for 2012, which is currently projected to be approximately $925.0 million. Of the $925.0 million
budget,  the  Company  plans  to  allocate  approximately  75%  to  exploration  and  development  related  expenditures  and  the  remainder  to  gathering  and
infrastructure and other.

Bank indebtedness.    The Company (through its subsidiary, Ultra Resources) was a party to a revolving credit facility with a syndicate of banks led by
JP  Morgan  Chase  Bank,  N.A.  which  was  to  mature  in  April  2012  (the  "2007  Credit  Agreement").  On  October  6,  2011,  in  anticipation  of  the  upcoming
maturity of the 2007 Credit Agreement, the Company, through Ultra Resources (the "Borrower"), replaced the 2007 Credit Agreement in its entirety with a
senior  unsecured  revolving  credit  facility  with  JP  Morgan  Chase  Bank,  N.A.  as  administrative  agent,  and  the  lenders  party  thereto  (the  "2011  Credit
Agreement") and repaid all amounts outstanding under the 2007 Credit Agreement with proceeds of loans drawn under the 2011 Credit Agreement.

The 2011 Credit Agreement reflects an increased borrowing capacity as compared to the 2007 Credit Agreement with an initial loan commitment of
$1.0 billion (which may be increased up to $1.25 billion at the request of the Borrower and with the lenders' consent), provides for the issuance of letters of
credit  of  up  to  $250.0  million  in  aggregate,  and  matures  in  five  years  (which  term  may  be  extended  for  up  to  two  successive  one-year  periods  at  the
Borrower's request and with the lenders' consent).

Loans under the 2011 Credit Agreement are unsecured and bear interest, at the Borrower's option, based on (A) a rate per annum equal to the prime rate
or  the  weighted  average  fed  funds  rate  on  overnight  transactions  during  the  preceding  business  day  plus  50  basis  points,  or  (B)  a  base  Eurodollar  rate,
substantially equal to the LIBOR rate, in either case plus a margin based on a grid of the Borrower's consolidated leverage ratio (for Eurodollar borrowings,
175 basis points per annum as of December 31, 2011). Payment of loans under the 2011 Credit Agreement are guaranteed by Ultra Petroleum Corp. and UP
Energy Corporation.

The 2011 Credit Agreement contains typical and customary representations, warranties, covenants and events of default. The 2011 Credit Agreement
includes restrictive covenants requiring the Borrower to maintain a consolidated leverage ratio of no greater than three and one half times to one and, as long
as the Company's debt rating is below investment grade, the maintenance of an annual ratio of the net present value of the Company's oil and gas properties to
total funded debt of no less than one and one half times to one. At December 31, 2011, the Company was in compliance with all of its debt covenants under
the 2011 Credit Agreement. (See Note 6).

Senior Notes:    The Company's Senior Notes rank pari passu with the Company's 2011 Credit Agreement. Payment of the Senior Notes is guaranteed

by Ultra Petroleum Corp. and UP Energy Corporation.

The  Senior  Notes  are  pre-payable  in  whole  or  in  part  at  any  time  and  are  subject  to  representations,  warranties,  covenants  and  events  of  default
customary for a senior note financing. At December 31, 2011, the Company was in compliance with all of its debt covenants under the Senior Notes. (See
Note 6).

Operating Activities.    During the year ended December 31, 2011, net cash provided by operating activities was $1.033 billion, a 25% increase from
$824.7 million for the same period in 2010. The increase in net cash provided by operating activities was largely attributable to increased production during
the year ended December 31, 2011 as compared to the same period in 2010.

Investing Activities.    During the year ended December 31, 2011, net cash used in investing activities was $1.4 billion as compared to $1.5 billion for

the same period in 2010. The decrease in net cash used in investing

47

 
 
Table of Contents

activities  is  largely  due  to  the  investments  associated  with  the  Pennsylvania  Marcellus  Shale  acquisition  in  2010,  partially  offset  by  increased  capital
investments associated with the Company's drilling activities in 2011 as compared to 2010.

Financing  Activities.        During  the  year  ended  December  31,  2011,  net  cash  provided  by  financing  activities  was  $316.0  million  as  compared  to
$761.0 million for the same period in 2010. The decrease in cash provided by net financing activities is largely due to increased borrowings during 2010,
primarily attributable to the 2010 Senior Notes offerings totaling approximately $1.025 billion.

Outlook

We believe we are well positioned for the current economic environment because of our status as a low cost operator in the industry combined with our
financial  flexibility.  In  2011,  the  Company  established  new  production  records  while  maintaining  a  low  cost  structure.  The  Company's  low  cost  structure
contributes to the Company's favorable returns and growth profile.

Although our net cash provided by operating activities was negatively affected by continued low natural gas prices, we believe that we will continue to
generate  positive  cash  flow  from  operations,  which,  along  with  our  available  cash,  will  provide  sufficient  liquidity  to  fund  our  capital  investments  and
operations over the next twelve months. We continue to monitor and evaluate the impact of reduced commodity prices in order to determine the appropriate
size and nature of our capital investment program.

We expect to rely on our available cash, our existing credit facility and the cash generated from operations to meet our obligations. While we continue
to monitor the overall health of the credit markets, a renewed, long-term disruption in the credit markets could make financing more expensive or unavailable,
which could have a material adverse effect on our operations.

Ohio. The Company's commitment involves a capacity of 200 MMMBtu per day of natural gas for a term of 10 years commencing in November 2009. During
the  first  quarter  of  2009,  the  Company  entered  into  agreements  to  secure  an  additional  capacity  of  50  MMMBtu  per  day  on  the  REX  pipeline  system,
beginning  in  January  2012  through  December  2018.  The  Company  is  obligated  to  pay  REX  certain  demand  charges  related  to  its  rights  to  hold  this  firm
transportation capacity as an anchor shipper. The Company has the right, but not the obligation, to deliver its natural gas production into the REX pipeline, but
must pay its reservation charges in either event. The Company continuously assesses its best available market options when determining the appropriate level
of utilization of its REX capacity.

Drilling contracts.    As of December 31, 2011, the Company had committed to drilling obligations with certain rig contractors that will continue into

2013. The drilling rigs were contracted to fulfill the 2012-2013 drilling program initiatives in Wyoming.

Office  space  lease.        The  Company  maintains  office  space  in  Colorado,  Texas,  Wyoming  and  Pennsylvania  with  total  remaining  commitments  for

office leases of $2.5 million at December 31, 2011 ($1.0 million in 2012 and $1.5 million in 2013 to 2015).

Item 7A. — Quantitative and Qualitative Disclosures About Market Risk

Objectives and Strategy:    The Company's major market risk exposure is in the pricing applicable to its natural gas and oil production. Realized pricing
is  currently  driven  primarily  by  the  prevailing  price  for  the  Company's  Wyoming  natural  gas  production.  Historically,  prices  received  for  natural  gas
production have been volatile and unpredictable. Pricing volatility is expected to continue.

The Company relies on various types of derivative instruments to manage its exposure to commodity price risk and to provide a level of certainty in the

Company's forward cash flows supporting the Company's capital investment program.

The Company's hedging policy limits the amounts of resources hedged to not more than 50% of its forecast production without Board approval. As a

result of its hedging activities, the Company may realize prices that are less than or greater than the spot prices that it would have received otherwise.

Commodity  Derivative  Contracts:        During  the  first  quarter  of  2009,  the  Company  converted  its  physical,  fixed  price,  forward  natural  gas  sales  to
physical, indexed natural gas sales combined with financial swaps whereby the Company receives the fixed price and pays the variable price. This change
provided operational flexibility to curtail gas production in the event of declines in natural gas prices. The contracts were converted at no cost to the Company
and  the  conversion  of  these  contracts  to  derivative  instruments  was  effective  upon  entering  into  these  transactions  in  March  2009,  with  settlements  for
production months through December 2010. The natural gas reference prices of these commodity derivative contracts are typically referenced to natural gas
index prices as published by independent third parties or natural gas futures settlement prices as traded on the NYMEX.

From time to time, the Company also utilizes fixed price forward gas sales to manage its commodity price exposure. These fixed price forward gas

sales are considered normal sales in the ordinary course of business and outside the scope of FASB ASC 815.

Fair Value of Commodity Derivatives:    FASB ASC 815 requires that all derivatives be recognized on the balance sheet as either an asset or liability
and be measured at fair value. Changes in the derivative's fair value are recognized currently in earnings unless specific hedge accounting criteria are met. The
Company does not apply hedge accounting to any of its derivative instruments. The application of hedge accounting was discontinued by the Company for
periods beginning on or after November 3, 2008.

Derivative contracts that do not qualify for hedge accounting treatment are recorded as derivative assets and liabilities at fair value on the balance sheet
and the associated unrealized gains and losses are recorded as current expense or income in the income statement. Unrealized gains or losses on commodity
derivatives represent the non-cash change in the fair value of these derivative instruments and do not impact operating cash flows on the cash flow statement.

At  December  31,  2011,  the  Company  had  the  following  open  commodity  derivative  contracts  to  manage  price  risk  on  a  portion  of  its  natural  gas
production  whereby  the  Company  receives  the  fixed  price  and  pays  the  variable  price.  See  Note  9  for  the  detail  of  the  asset  and  liability  values  of  the
following derivatives. The Board has approved our hedging greater than 50% of our forecast 2012 production.

Financial Statements and Supplementary Data. 

MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The management of the Company is responsible for the preparation and integrity of all information contained in this Annual Report. The accompanying
financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America. The financial statements
include amounts that are management's best estimates and judgments.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange
Act Rules 13a-15(f). Under the supervision and with the participation of our management, including our chief executive officer and chief financial officer, we
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 our evaluation under the framework in Internal
Control — Integrated Framework, our management concluded that our internal control over financial reporting was effective as of December 31, 2011.

The effectiveness of our internal control over financial reporting has been audited by Ernst & Young LLP, an independent registered public accounting

firm, as stated in their report which is included herein.

The Board of Directors and Shareholders of Ultra Petroleum Corp.

Report of Independent Registered Public Accounting Firm

We  have  audited  the  accompanying  consolidated  balance  sheets  of  Ultra  Petroleum  Corp.  as  of  December  31,  2011  and  2010,  and  the  related
consolidated statements of operations, shareholders' equity, and cash flows for each of the three years in the period ended December 31, 2011. These financial
statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

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

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Ultra Petroleum
Corp.  at  December  31,  2011  and  2010,  and  the  consolidated  results  of  its  operations  and  its  cash  flows  for  each  of  the  three  years  in  the  period  ended
December 31, 2011, in conformity with U.S. generally accepted accounting principles.

As  discussed  in  Note  1  to  the  consolidated  financial  statements,  the  Company  changed  its  reserve  estimates  and  related  disclosures  as  a  result  of

adopting new oil and gas reserve estimation and disclosure requirements as of December 31, 2009.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Ultra Petroleum Corp.'s
internal  control  over  financial  reporting  as  of  December  31,  2011,  based  on  criteria  established  in  Internal  Control-Integrated  Framework  issued  by  the
Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 17, 2012 expressed an unqualified opinion thereon.

The Board of Directors and Shareholders of Ultra Petroleum Corp.

Report of Independent Registered Public Accounting Firm

We have audited Ultra Petroleum Corp.'s internal control over financial reporting as of December 31, 2011, based on criteria established in Internal
Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). Ultra Petroleum
Corp.'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, Ultra Petroleum Corp. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2011,

based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance
sheets of Ultra Petroleum Corp. as of December 31, 2011 and 2010 and the related consolidated statements of operations, shareholders' equity and cash flows
for each of the three years in the period ended December 31, 2011 of Ultra Petroleum Corp. and our report dated February 17, 2012 expressed an unqualified
opinion thereon.

ULTRA PETROLEUM CORP.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(All amounts in this Report on Form 10-K are expressed in thousands of U.S. dollars (except per share data), unless otherwise noted).

Ultra  Petroleum  Corp.  (the  "Company")  is  an  independent  oil  and  natural  gas  company  engaged  in  the  acquisition,  exploration,  development,  and
production of oil and natural gas properties. The Company is incorporated under the laws of the Yukon Territory, Canada. The Company's principal business
activities are in the Green River Basin of southwest Wyoming and the north-central Pennsylvania area of the Appalachian Basin. In addition, the Company
has recently acquired acreage in eastern Colorado's Denver Julesburg Basin.

1.    SIGNIFICANT ACCOUNTING POLICIES:

(a) Basis of presentation and principles of consolidation:    The consolidated financial statements include the accounts of the Company and its wholly
owned subsidiaries. The Company presents its financial statements in accordance with U.S. Generally Accepted Accounting Principles ("GAAP"). All inter-
company transactions and balances have been eliminated upon consolidation.

(b) Cash and cash equivalents:    The Company considers all highly liquid investments with an original maturity of three months or less to be cash

equivalents.

(c)  Restricted  cash:        Restricted  cash  represents  cash  received  by  the  Company  from  production  sold  where  the  final  division  of  ownership  of  the

production is unknown or in dispute. Wyoming law requires that these funds be held in a federally insured bank in Wyoming.

(d)  Property,  plant  and  equipment:        Capital  assets  are  recorded  at  cost  and  depreciated  using  the  declining-balance  method  based  on  a  seven-year

useful life. Gathering system expenditures are recorded at cost and depreciated using the straight-line method based on a 30-year useful life.

(e)  Oil  and  natural  gas  properties:        On  January  6,  2010,  the  FASB  issued  an  ASU  updating  oil  and  gas  reserve  estimation  and  disclosure
requirements.  The  ASU  amends  FASB  ASC  932  to  align  the  reserve  calculation  and  disclosure  requirements  with  the  requirements  in  SEC  Release
No. 33-8995. SEC Release No. 33-8995, amends oil and gas reporting requirements under Rule 4-10 of Regulation S-X and Industry Guide 2 in Regulation S-
K revising oil and gas reserves estimation and disclosure requirements. The rules include changes to pricing used to estimate reserves, the ability to include
non-traditional resources in reserves, the use of new technology for determining reserves and permitting disclosure of probable and possible reserves. The
primary objectives of the revisions are to increase the transparency and information value of reserve disclosures and improve comparability among oil and gas
companies. Accordingly, the Company adopted the update to FASB ASC 932 as of December 31, 2009. The implementation of this rule did not result in
material additions to the Company's proved reserves included in this report.

The  Company  uses  the  full  cost  method  of  accounting  for  exploration  and  development  activities  as  defined  by  the  Securities  and  Exchange
Commission ("SEC"). Separate cost centers are maintained for each country in which the Company incurs costs. Under this method of accounting, the costs of
unsuccessful, as well as successful, exploration and development activities are capitalized as properties and equipment. This includes any internal costs that
are  directly  related  to  exploration  and  development  activities  but  does  not  include  any  costs  related  to  production,  general  corporate  overhead  or  similar
activities. The carrying amount of oil and natural gas properties also includes estimated asset retirement costs recorded based on the fair value of the asset
retirement obligation when incurred. Gain or loss on the sale or other disposition of oil and natural gas properties is not recognized, unless the gain or loss
would significantly alter the relationship between capitalized costs and proved reserves of oil and natural gas attributable to a country.

ULTRA PETROLEUM CORP.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

The sum of net capitalized costs and estimated future development costs of oil and natural gas properties are amortized using the units-of-production
method  based  on  the  proved  reserves  as  determined  by  independent  petroleum  engineers.  Oil  and  natural  gas  reserves  and  production  are  converted  into
equivalent units based on relative energy content. Asset retirement obligations are included in the base costs for calculating depletion.

Under  the  full  cost  method,  costs  of  unevaluated  properties  and  major  development  projects  expected  to  require  significant  future  costs  may  be
excluded from capitalized costs being amortized. The Company excludes significant costs until proved reserves are found or until it is determined that the
costs are impaired. Excluded costs, if any, are reviewed quarterly to determine if impairment has occurred. The amount of any impairment is transferred to the
capitalized costs being amortized.

Companies that use the full cost method of accounting for oil and natural gas exploration and development activities are required to perform a ceiling
test  calculation  each  quarter.  The  full  cost  ceiling  test  is  an  impairment  test  prescribed  by  SEC  Regulation  S-X  Rule  4-10.  The  ceiling  test  is  performed
quarterly,  on  a  country-by-country  basis,  utilizing  the  average  of  prices  in  effect  on  the  first  day  of  the  month  for  the  preceding  twelve  month  period  in
accordance with SEC Release No. 33-8995. The ceiling limits such pooled costs to the aggregate of the present value of future net revenues attributable to
proved crude oil and natural gas reserves discounted at 10% plus the lower of cost or market value of unproved properties less any associated tax effects. If
such  capitalized  costs  exceed  the  ceiling,  the  Company  will  record  a  write-down  to  the  extent  of  such  excess  as  a  non-cash  charge  to  earnings.  Any  such
write-down will reduce earnings in the period of occurrence and results in a lower depletion, depreciation and amortization ("DD&A") rate in future periods.
A write-down may not be reversed in future periods even though higher oil and natural gas prices may subsequently increase the ceiling.

(f)  Inventories:        Materials  and  supplies  inventories  are  carried  at  lower  of  cost  or  market.  Inventory  costs  include  expenditures  and  other  charges
directly and indirectly incurred in bringing the inventory to its existing condition and location. The Company uses the weighted average method of recording
its inventory. Selling expenses and general and administrative expenses are reported as period costs and excluded from inventory cost. At December 31, 2011,
inventory of $1.2 million primarily includes the cost of pipe and production equipment that will be utilized during the 2012 drilling program.

(g) Derivative instruments and hedging activities:    Currently, the Company largely relies on commodity derivative contracts to manage its exposure to
commodity price risk. These commodity derivative contracts are typically referenced to natural gas index prices as published by independent third parties.
Additionally, and from time to time, the Company enters into physical, fixed price forward natural gas sales in order to mitigate its commodity price exposure
on a portion of its natural gas production. These fixed price forward gas sales are considered normal sales in the ordinary course of business and outside the
scope of FASB ASC Topic 815, Derivatives and Hedging ("FASB ASC 815"). The Company does not offset the value of its derivative arrangements with the
same counterparty. (See Note 8).

(h) Income taxes:    Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future
tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis
and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in
the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates
is recognized in income in the period that includes the enactment date. Valuation allowances are recorded related to deferred tax assets based on the "more
likely than not" criteria described in FASB ASC Topic 740, Income Taxes. In addition, the Company recognizes

the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following
an audit.

(i) Earnings per share:    Basic earnings per share is computed by dividing net earnings attributable to common stockholders by the weighted average
number  of  common  shares  outstanding  during  each  period.  Diluted  earnings  per  share  is  computed  by  adjusting  the  average  number  of  common  shares
outstanding for the dilutive effect, if any, of common stock equivalents. The Company uses the treasury stock method to determine the dilutive effect.

The following table provides a reconciliation of components of basic and diluted net income (loss) per common share:

(1) Due to the net loss for the year ended December 31, 2009, 2.2 million shares for options and restricted stock units were anti-dilutive and excluded from

the computation of loss per share.

(j) Use of estimates:    Preparation of consolidated financial statements in accordance with U.S. GAAP requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements,
and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

(k) Accounting for share-based compensation:    The Company measures and recognizes compensation expense for all share-based payment awards
made to employees and directors, including employee stock options, based on estimated fair values in accordance with FASB ASC Topic 718, Compensation
– Stock Compensation.

(l)  Fair  value  accounting:        The  Company  follows  FASB  ASC  Topic  820,  Fair  Value  Measurements  and  Disclosures  ("FASB  ASC  820"),  which
defines  fair  value,  establishes  a  framework  for  measuring  fair  value  under  GAAP,  and  expands  disclosures  about  fair  value  measurements.  This  statement
applies under other accounting topics that require or permit fair value measurements. See Note 9 for additional information.

(m) Asset retirement obligation:    The initial estimated retirement obligation of properties is recognized as a liability with an associated increase in oil

and gas properties for the asset retirement cost. Accretion expense is

recognized  over  the  estimated  productive  life  of  the  related  assets.  If  the  fair  value  of  the  estimated  asset  retirement  obligation  changes,  an  adjustment  is
recorded to both the asset retirement obligation and the asset retirement cost. Revisions in estimated liabilities can result from revisions of estimated inflation
rates, changes in service and equipment costs and changes in the estimated timing of settling asset retirement obligations.

(n)  Revenue  recognition:        The  Company  generally  sells  natural  gas  and  condensate  under  both  long-term  and  short-term  agreements  at  prevailing
market prices and under multi-year contracts that provide for a fixed price of oil and natural gas. The Company recognizes revenues when the oil and natural
gas is delivered, which occurs when the customer has taken title and has assumed the risks and rewards of ownership, prices are fixed or determinable and
collectability  is  reasonably  assured.  The  Company  accounts  for  oil  and  natural  gas  sales  using  the  "entitlements  method."  Under  the  entitlements  method,
revenue is recorded based upon the Company's ownership share of volumes sold, regardless of whether it has taken its ownership share of such volumes. The
Company records a receivable or a liability to the extent it receives less or more than its share of the volumes and related revenue. Any amount received in
excess of the Company's share is treated as a liability. If the Company receives less than its entitled share, the underproduction is recorded as a receivable. At
December 31, 2011 and 2010, the Company had a net natural gas imbalance liability of $1.3 million and $0.9 million, respectively.

Make-up provisions and ultimate settlements of volume imbalances are generally governed by agreements between the Company and its partners with
respect to specific properties or, in the absence of such agreements, through negotiation. The value of volumes over- or under-produced can change based on
changes in commodity prices. The Company prefers the entitlements method of accounting for oil and natural gas sales because it allows for recognition of
revenue based on its actual share of jointly owned production, results in better matching of revenue with related operating expenses, and provides balance
sheet recognition of the estimated value of product imbalances.

(o) Capitalized interest:    Interest is capitalized on the cost of unevaluated gas and oil properties that are excluded from amortization and actively being

evaluated as well as on work in process relating to gathering systems that are not currently in service.

(p)  Capital  cost  accrual:        The  Company  accrues  for  exploration  and  development  costs  in  the  period  incurred,  while  payment  may  occur  in  a

subsequent period.

(q) Reclassifications:    Certain amounts in the financial statements of prior periods have been reclassified to conform to the current period financial

statement presentation.

(r) Recent accounting pronouncements:    In May 2011, the FASB issued ASU No. 2011-04, which amends FASB ASC 820. The amended guidance
clarifies  many  requirements  in  U.S.  GAAP  for  measuring  fair  value  and  for  disclosing  information  about  fair  value  measurements.  Additionally,  the
amendments clarify the FASB's intent about the application of existing fair value measurement requirements. The guidance provided in ASU No. 2011-04 is
effective for interim and annual periods beginning after December 15, 2011. The Company does not expect the adoption of this amendment to have a material
impact on its consolidated financial statements.

2.    OTHER COMPREHENSIVE INCOME:

Other comprehensive income (loss) is a term used to define revenues, expenses, gains and losses that under generally accepted accounting principles

impact Shareholders' Equity, excluding transactions with shareholders.

* Effective November 3, 2008, the Company changed its method of accounting for natural gas commodity derivatives to reflect unrealized gains and losses
on  commodity  derivative  contracts  in  the  income  statement  rather  than  on  the  balance  sheet  (See  Note  8).  The  net  gain  or  loss  in  accumulated  other
comprehensive income at November 3, 2008 remained on the balance sheet and the respective month's gains or losses were reclassified from accumulated
other  comprehensive  income  to  earnings  as  the  counterparty  settlements  affected  earnings  (January  through  December  2009).  As  a  result  of  the  de-
designation on November 3, 2008, the Company no longer has any derivative instruments which qualify for cash flow hedge accounting.

3.    ASSET RETIREMENT OBLIGATIONS:

The  Company  is  required  to  record  the  fair  value  of  an  asset  retirement  obligation  as  a  liability  in  the  period  in  which  it  incurs  a  legal  obligation
associated with the retirement of tangible long-lived assets that result from the acquisition, construction, development and/or normal use of the assets. The
following table summarizes the activities for the Company's asset retirement obligations for the years ended:

In  2010,  a  wholly-owned  subsidiary  of  the  Company  acquired,  for  $403.8  million  in  cash,  non-producing  mineral  acres  and  a  small  number  of
producing gas wells in the Pennsylvania Marcellus Shale. Additionally, the Company purchased additional undeveloped acreage in the Marcellus Shale
for approximately $63.4 million during 2010.

Interest is capitalized on the cost of unevaluated oil and natural gas properties that are excluded from amortization and actively being evaluated as well
as on work in process relating to gathering systems that are not currently in service. For the years ended December 31, 2011 and 2010, total interest on
outstanding debt was $93.9 million and $70.2 million, respectively, of which, $30.7 million and $21.2 million, respectively, was capitalized on the cost
of unevaluated oil and natural gas properties and work in process relating to gathering systems that are not currently in service.

The Company holds interests in domestic projects in which costs related to these interests are not being depleted pending determination of existence of
estimated  proved  reserves.  The  Company  will  continue  to  assess  and  allocate  the  unproven  properties  over  the  next  several  years  as  proved  reserves  are
established and as exploration dictates whether or not future areas will be developed.

Historically, the Company's condensate production was gathered from its Wyoming well locations by tanker trucks and then shipped to other locations
for injection into crude oil pipelines or other facilities. During 2010, the Company initiated service on its final two, of four total, central gathering facilities.
These facilities are part of the Company's liquids gathering system designed to gather condensate and water from various leases and wells operated by the
Company. The condensate and water are transported to central points in the field where condensate can be loaded into trucks or delivered into pipelines for
delivery to the Company's customers.

Produced water is disposed of or recycled and re-used. At the end of 2011, more than 80% of the Company's operated condensate production in Wyoming was
delivered from the Company's liquids gathering system directly into a pipeline, further reducing truck traffic and improving flow assurance as well as realized
pricing.

In Pennsylvania, the Company and its partners continue constructing gas gathering pipelines and facilities, compression facilities and pipeline delivery
stations to gather production from its newly completed natural gas wells. Construction on these facilities is expected to continue throughout 2012 allowing the
Company to manage its midstream capacity to coincide with increased capacity requirements from its drilling activities. These facilities are gathering systems
and related infrastructure, and their construction is expected to continue until the Company's properties in Pennsylvania are fully developed. To date, none of
the Company's natural gas production in Pennsylvania has required processing, treating or blending in order to remove natural gas liquids or other impurities
and it is anticipated that facilities of this type will not be required in the future to accommodate the Company's production.

Aggregate maturities of debt at December 31, 2011:

Bank indebtedness.    The Company (through its subsidiary, Ultra Resources) was a party to a revolving credit facility with a syndicate of banks led by
JP  Morgan  Chase  Bank,  N.A.  which  was  to  mature  in  April  2012  (the  "2007  Credit  Agreement").  On  October  6,  2011,  in  anticipation  of  the  upcoming
maturity of the 2007 Credit Agreement, the Company, through Ultra Resources (the "Borrower"), replaced the 2007 Credit Agreement in its entirety with a
senior  unsecured  revolving  credit  facility  with  JP  Morgan  Chase  Bank,  N.A.  as  administrative  agent,  and  the  lenders  party  thereto  (the  "2011  Credit
Agreement") and repaid all amounts outstanding under the 2007 Credit Agreement with proceeds of loans drawn under the 2011 Credit Agreement.

The 2011 Credit Agreement reflects an increased borrowing capacity as compared to the 2007 Credit Agreement with an initial loan commitment of
$1.0 billion (which may be increased up to $1.25 billion at the request of the Borrower and with the lenders' consent), provides for the issuance of letters of
credit  of  up  to  $250.0  million  in  aggregate,  and  matures  in  October  2016  (which  term  may  be  extended  for  up  to  two  successive  one-year  periods  at  the
Borrower's request and with the lenders' consent).

Loans under the 2011 Credit Agreement are unsecured and bear interest, at the Borrower's option, based on (A) a rate per annum equal to the prime rate
or  the  weighted  average  fed  funds  rate  on  overnight  transactions  during  the  preceding  business  day  plus  50  basis  points,  or  (B)  a  base  Eurodollar  rate,
substantially equal to the LIBOR rate, in either case plus a margin based on a grid of the Borrower's consolidated leverage ratio (for Eurodollar borrowings,
175 basis points per annum as of December 31, 2011). Payment of loans under the 2011

Credit  Agreement  are  guaranteed  by  Ultra  Petroleum  Corp.  and  UP  Energy  Corporation.  The  Company  also  pays  commitment  fees  on  the  unused
commitment under the facility based on a grid of our consolidated leverage ratio.

The 2011 Credit Agreement contains typical and customary representations, warranties, covenants and events of default. The 2011 Credit Agreement
includes restrictive covenants requiring the Borrower to maintain a consolidated leverage ratio of no greater than three and one half times to one and, as long
as the Company's debt rating is below investment grade, the maintenance of an annual ratio of the net present value of the Company's oil and gas properties to
total funded debt of no less than one and one half times to one. At December 31, 2011, the Company was in compliance with all of its debt covenants under
the 2011 Credit Agreement.

Senior Notes:    The Company's Senior Notes rank pari passu with the Company's 2011 Credit Agreement. Payment of the Senior Notes is guaranteed

by Ultra Petroleum Corp. and UP Energy Corporation.

The  Senior  Notes  are  pre-payable  in  whole  or  in  part  at  any  time  and  are  subject  to  representations,  warranties,  covenants  and  events  of  default

customary for a senior note financing. At December 31, 2011, the Company was in compliance with all of its debt covenants under the Senior Notes.

Other long-term obligations:    These costs primarily relate to the long-term portion of production taxes payable and our asset retirement obligations.

SHARE BASED COMPENSATION:

The  Company  sponsors  a  share  based  compensation  plan:  the  2005  Stock  Incentive  Plan  (the  "2005  Plan").  The  plan  is  administered  by  the
Compensation  Committee  of  the  Board  of  Directors  (the  "Committee").  The  share  based  compensation  plan  is  an  important  component  of  the  total
compensation  package  offered  to  the  Company's  key  service  providers,  and  reflects  the  importance  that  the  Company  places  on  motivating  and  rewarding
superior results.

The 2005 Plan was adopted by the Company's Board of Directors on January 1, 2005 and approved by the Company's shareholders on April 29, 2005.
The  purpose  of  the  2005  Plan  is  to  foster  and  promote  the  long-term  financial  success  of  the  Company  and  to  increase  shareholder  value  by  attracting,
motivating  and  retaining  key  employees,  consultants,  and  outside  directors,  and  providing  such  participants  with  a  program  for  obtaining  an  ownership
interest in the Company that links and aligns their personal interests with those of the Company's shareholders, and thus, enabling such participants to share in
the long-term growth and success of the Company. To accomplish these goals, the 2005 Plan permits the granting of incentive stock options, non-statutory
stock  options,  stock  appreciation  rights,  restricted  stock,  and  other  stock-based  awards,  some  of  which  may  require  the  satisfaction  of  performance-based
criteria in order to be payable to participants. The Committee determines the terms and conditions of the awards, including, any vesting requirements and
vesting restrictions or forfeitures that may occur. The Committee may grant awards under the 2005 Plan until December 31, 2014, unless terminated sooner
by the Board of Directors.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

long-term performance of the Company when specific corporate financial and operational goals are achieved. Each LTIP covers a performance period of three
years. In 2009, 2010 and 2011, the Compensation Committee (the "Committee") approved an award consisting of performance-based restricted stock units to
be awarded to each participant.

For each LTIP award, the Committee establishes performance measures at the beginning of each performance period. Under each LTIP, the Committee
establishes a percentage of base salary for each participant which is multiplied by the participant's base salary to derive a Long Term Incentive Value as a
"target"  value  which  corresponds  to  the  number  of  shares  of  the  Company's  common  stock  the  participant  is  eligible  to  receive  if  the  target  level  for  all
performance measures is met. In addition, each participant is assigned threshold and maximum award levels in the event that actual performance is below or
above  target  levels.  For  the  2009,  2010  and  2011  LTIP  awards,  the  Committee  established  the  following  performance  measures:  return  on  equity,  reserve
replacement ratio, and production growth.

For the year ended December 31, 2011, the Company recognized $10.7 million in pre-tax compensation expense related to the 2009, 2010 and 2011
LTIP awards of restricted stock units. For the year ended December 31, 2010, the Company recognized $8.6 million in pre-tax compensation expense related
to the 2008, 2009 and 2010 LTIP awards of restricted stock units. For the year ended December 31, 2009, the Company recognized $5.8 million in pre-tax
compensation expense related to the 2007, 2008 and 2009 LTIP awards of restricted stock units. The amounts recognized during the year ended December 31,
2011  assumes  that  maximum  performance  objectives  are  attained.  If  the  Company  ultimately  attains  these  performance  objectives,  the  associated  total
compensation, estimated at December 31, 2011, for each of the three year performance periods is expected to be approximately $24.1 million, $12.0 million,
and $12.1 million related to the 2009, 2010 and 2011 LTIP awards of restricted stock units, respectively. The 2008 LTIP Common Stock Award was paid in
shares of the Company's stock to employees during the first quarter of 2011 and totaled $4.3 million (41,443 net shares).

DERIVATIVE FINANCIAL INSTRUMENTS:

Objectives and Strategy:    The Company's major market risk exposure is in the pricing applicable to its natural gas and oil production. Realized pricing
is  currently  driven  primarily  by  the  prevailing  price  for  the  Company's  Wyoming  natural  gas  production.  Historically,  prices  received  for  natural  gas
production have been volatile and unpredictable. Pricing volatility is expected to continue.

The Company relies on various types of derivative instruments to manage its exposure to commodity price risk and to provide a level of certainty in the

Company's forward cash flows supporting the Company's capital investment program.

The Company's hedging policy limits the amounts of resources hedged to not more than 50% of its forecast production without Board approval. As a
result of its hedging activities, the Company may realize prices that are less than or greater than the spot prices that it would have received otherwise. The
Company's board approved hedging greater than 50% of the Company's forecast 2011 production.

Commodity  Derivative  Contracts:        During  the  first  quarter  of  2009,  the  Company  converted  its  physical,  fixed  price,  forward  natural  gas  sales  to
physical, indexed natural gas sales combined with financial swaps whereby the Company receives the fixed price and pays the variable price. This change
provided operational flexibility to curtail gas production in the event of declines in natural gas prices. The contracts were converted at no cost to the Company
and  the  conversion  of  these  contracts  to  derivative  instruments  was  effective  upon  entering  into  these  transactions  in  March  2009,  with  settlements  for
production months through December 2010.

ULTRA PETROLEUM CORP.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

The natural gas reference prices of these commodity derivative contracts are typically referenced to natural gas index prices as published by independent third
parties or natural gas futures settlement prices as traded on the NYMEX.

From time to time, the Company also utilizes fixed price forward gas sales to manage its commodity price exposure. These fixed price forward gas

sales are considered normal sales in the ordinary course of business and outside the scope of FASB ASC 815, Derivatives and Hedging.

Fair Value of Commodity Derivatives:    FASB ASC 815 requires that all derivatives be recognized on the balance sheet as either an asset or liability
and be measured at fair value. Changes in the derivative's fair value are recognized currently in earnings unless specific hedge accounting criteria are met. The
Company does not apply hedge accounting to any of its derivative instruments. The application of hedge accounting was discontinued by the Company for
periods beginning on or after November 3, 2008.

Derivative contracts that do not qualify for hedge accounting treatment are recorded as derivative assets and liabilities at fair value on the balance sheet
and the associated unrealized gains and losses are recorded as current expense or income in the income statement. Unrealized gains or losses on commodity
derivatives represent the non-cash change in the fair value of these derivative instruments and do not impact operating cash flows on the cash flow statement.

At  December  31,  2011,  the  Company  had  the  following  open  commodity  derivative  contracts  to  manage  price  risk  on  a  portion  of  its  natural  gas
production  whereby  the  Company  receives  the  fixed  price  and  pays  the  variable  price.  See  Note  9  for  the  detail  of  the  asset  and  liability  values  of  the
following derivatives. The Board has approved our hedging greater than 50% of our forecast 2012 production.

FAIR VALUE MEASUREMENTS:

As required by the Fair Value Measurements and Disclosure Topic of the FASB Accounting Standards Codification, we define fair value as the price
that  would  be  received  to  sell  an  asset  or  paid  to  transfer  a  liability  in  an  orderly  transaction  between  market  participants  at  the  measurement  date  and
establishes a three level hierarchy for measuring fair value. Fair value measurements are classified and disclosed in one of the following categories:

Level 1: Quoted prices (unadjusted) in active markets for identical assets and liabilities that we have the ability to access at the measurement date.

Level 2: Inputs other than quoted prices included within Level 1 that are either directly or indirectly observable for the asset or liability, including
quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in inactive markets, inputs other
than quoted prices that are observable for the asset or liability, and inputs that are derived from observable market data by correlation or other means.
Instruments categorized in Level 2 include non-exchange traded derivatives such as over-the-counter forwards and swaps.

Level 3: Unobservable inputs for the asset or liability, including situations where there is little, if any, market activity for the asset or liability.

The valuation assumptions utilized to measure the fair value of the Company's commodity derivatives were observable inputs based on market data

obtained from independent sources and are considered Level 2 inputs (quoted prices for similar assets, liabilities (adjusted) and market-corroborated inputs).

The following table presents for each hierarchy level our assets and liabilities, including both current and non-current portions, measured at fair value

on a recurring basis, as of December 31, 2011. The company has no derivative instruments which qualify for cash flow hedge accounting.

in the derivative instrument in determining the fair value. Additionally, the Company considers that it is of substantial credit quality and has the financial
resources and willingness to meet its potential repayment obligations associated with the derivative transactions.

Fair Value of Financial Instruments

The  estimated  fair  value  of  financial  instruments  is  the  amount  at  which  the  instrument  could  be  exchanged  currently  between  willing  parties.  The
carrying amounts reported in the consolidated balance sheet for cash and cash equivalents, accounts receivable, and accounts payable approximate fair value
due  to  the  immediate  or  short-term  maturity  of  these  financial  instruments.  The  carrying  amount  of  floating-rate  debt  approximates  fair  value  because  the
interest rates are variable and reflective of market rates. We use available market data and valuation methodologies to estimate the fair value of our fixed rate
debt.  This  disclosure  is  presented  in  accordance  with  FASB  ASC  Topic  825,  Financial  Instruments,  and  does  not  impact  our  financial  position,  results  of
operations or cash flows.

assets  is  dependent  upon  the  generation  of  future  taxable  income  during  the  periods  in  which  the  temporary  differences  become  deductible.  Among  other
items, management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and available tax planning strategies.

The  Company  did  not  have  any  unrecognized  tax  benefits  and  there  was  no  effect  on  our  financial  condition  or  results  of  operations  as  a  result  of
implementing  the  standard  related  to  accounting  for  uncertain  tax  positions.  The  amount  of  unrecognized  tax  benefits  did  not  change  as  of  December  31,
2011.

It is expected that the amount of unrecognized tax benefits may change in the next twelve months; however Ultra does not expect the change to have a
significant  impact  on  the  results  of  operations  or  the  financial  position  of  the  Company.  The  Company  currently  has  no  unrecognized  tax  benefits  that  if
recognized would affect the effective tax rate.

Estimated interest and penalties related to potential underpayment on any unrecognized tax benefits are classified as a component of tax expense in the

Consolidated Statement of Operations. The Company has not recorded any interest or penalties associated with unrecognized tax benefits.

The Company files a consolidated federal income tax return in the United States federal jurisdiction and various combined, consolidated, unitary, and
separate filings in several states, and international jurisdictions. With certain exceptions, the Company is no longer subject to U.S. federal, state and local, or
non-U.S. income tax examinations by tax authorities for years before 2008.

As of December 31, 2011, the Company had approximately $11.6 million of U.S. federal alternative minimum tax (AMT) credits available to offset
regular  U.S.  federal  income  taxes.  These  AMT  credits  do  not  expire  and  can  be  carried  forward  indefinitely.  In  addition,  as  of  December  31,  2011,  the
Company has $1.7 million of foreign tax credit carryforwards, none of which expire prior to 2017. However, with the 2007 sale of Sino American Energy, the
Company no longer has foreign source income for which to utilize its foreign tax credit carryforwards. Therefore, a valuation allowance has been placed on
the remaining foreign tax credit carryforwards.

The Company had an unutilized capital loss carryforward of approximately $5.4 million as of December 31, 2011. The majority of this carryforward
expires  in  2013.  Due  to  the  unpredictability  of  future  capital  gains  that  would  allow  for  the  utilization  of  this  carryforward,  a  valuation  allowance  has  be
placed on the full amount of the carryforward.

The Company had Canadian net operating loss carryforwards of approximately $2.7 million as of December 31, 2009. The unexpired portion of the
Canadian  net  operating  loss  carryforward  was  fully  utilized  in  2010,  and  thus  the  valuation  allowance  at  December  31,  2009  has  been  removed  and  no
deferred tax asset related to the Canadian net operating loss exists as of December 31, 2010.

The undistributed earnings of the Company's U.S. subsidiaries are considered to be indefinitely invested outside of Canada. Accordingly, no provision

for Canadian income taxes and/or withholding taxes has been provided thereon.

The  Company  periodically  uses  derivative  instruments  designated  as  cash  flow  hedges  for  tax  purposes  as  a  method  of  managing  its  exposure  to
commodity  price  fluctuations.  To  the  extent  these  hedges  are  effective,  changes  in  the  fair  value  of  these  derivative  instruments  are  recorded  in  Other
Comprehensive Income, net of income tax. To the extent these hedges are ineffective, they are marked to market with gains and losses recorded

in the statement of operations. At December 31, 2011 and 2010, the Company also recorded a total deferred tax liability of $82.7 million and $46.2 million,
respectively, attributable to the unrealized gains and losses recorded in the statement of operations.

11. EMPLOYEE BENEFITS:

The  Company  sponsors  a  qualified,  tax-deferred  savings  plan  in  accordance  with  provisions  of  Section  401(k)  of  the  Internal  Revenue  Code  for  its
employees.  Employees  may  defer  up  to  100%  of  their  compensation,  subject  to  certain  limitations.  The  Company  matches  100%  of  the  employee's
contribution up to 5% of compensation, as defined by the plan, along with an employer discretionary contribution of 8%. The expense associated with the
Company's contribution was $1.4 million, $1.2 million and $1.1 million for the years ended December 31, 2011, 2010 and 2009, respectively.

12. COMMITMENTS AND CONTINGENCIES:

Transportation  contract.        The  Company  is  an  anchor  shipper  on  REX  securing  pipeline  infrastructure  providing  sufficient  capacity  to  transport  a
portion of its natural gas production away from southwest Wyoming and to provide for reasonable basis differentials for its natural gas in the future. REX
begins  at  the  Opal  Processing  Plant  in  southwest  Wyoming  and  traverses  Wyoming  and  several  other  states  to  an  ultimate  terminus  in  eastern  Ohio.  The
Company's commitment involves a capacity of 200 MMMBtu per day of natural gas for a term of 10-years commencing in November 2009, and the Company
is obligated to pay REX certain demand charges related to its rights to hold this firm transportation capacity as an anchor shipper.

Subsequently, the Company entered into agreements to secure an additional capacity of 50 MMMBtu per day on the REX pipeline system, beginning in
January 2012 through December 2018. This additional capacity will provide the Company with the ability to move additional volumes from its producing
wells in Wyoming to markets in the eastern U.S.

The Company currently projects that demand charges related to the remaining term of the contract will total approximately $776.3 million.

Drilling contracts.    As of December 31, 2011, the Company had committed to drilling obligations with certain rig contractors totaling $60.5 million
($45.5  million  due  in  2012,  $15.0  million  due  in  2013).  The  commitments  expire  in  2013  and  were  entered  into  to  fulfill  the  Company's  drilling  program
initiatives in Wyoming.

Office space lease.    The Company's maintains office space in Colorado, Texas, Wyoming and Pennsylvania with total remaining commitments for

office leases of $2.5 million at December 31, 2011 ($1.0 million in 2012, $1.5 million in 2013 to 2015).

During  the  years  ended  December  31,  2011,  2010  and  2009,  the  Company  recognized  expense  associated  with  its  office  leases  in  the  amount  of

$0.9 million, $0.8 million, and $0.9 million, respectively.

Other.    The Company is currently involved in various routine disputes and allegations incidental to its business operations. While it is not possible to
determine the ultimate disposition of these matters, management, after consultation with legal counsel, is of the opinion that the final resolution of all such
currently pending or threatened litigation is not likely to have a material adverse effect on the consolidated financial position, results of operations or cash
flows of the Company.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

13. CONCENTRATION OF CREDIT RISK:

The Company's financial instruments that are exposed to concentrations of credit risk consist primarily of trade receivables and commodity derivative
contracts associated with the Company's hedging program. The Company's revenues related to natural gas sales are derived principally from a diverse group
of companies, including major energy companies, natural gas utilities, oil refiners, pipeline companies, local distribution companies, financial institutions and
end-users in various industries.

Concentrations of credit risk with respect to receivables is limited due to the large number of customers and their dispersion across geographic areas.
Commodity-based contracts may expose the Company to the credit risk of nonperformance by the counterparty to these contracts. This credit exposure to the
Company  is  diversified  primarily  among  as  many  as  ten  major  investment  grade  institutions  and  will  only  be  present  if  the  reference  price  of  natural  gas
established in those contracts is less than the prevailing market price of natural gas, from time to time.

The Company maintains credit policies intended to monitor and mitigate the risk of uncollectible accounts receivable related to the sale of natural gas,
condensate as well as its commodity derivative positions. The Company performs a credit analysis of each of its customers and counterparties prior to making
any sales to new customers or extending additional credit to existing customers. Based upon this credit analysis, the Company may require a standby letter of
credit  or  a  financial  guarantee.  The  Company  did  not  have  any  outstanding,  uncollectible  accounts  for  its  natural  gas  or  condensate  sales,  nor  derivative
settlements sales at December 31, 2011.

A significant counterparty is defined as one that individually accounts for 10% or more of the Company's total revenues during the year. In 2011, the

Company had no single customer that represented 10% or more of its total revenues.

14.

SUBSEQUENT EVENTS:

FASB ASC Topic 855, Subsequent Events ("FASB ASC 855"), sets forth principles and requirements to be applied to the accounting for and disclosure
of subsequent events. FASB ASC 855 sets forth the period after the balance sheet date during which management shall evaluate events or transactions that
may occur for potential recognition or disclosure in the financial statements, the circumstances under which events or transactions occurring after the balance
sheet date shall be recognized in the financial statements and the required disclosures about events or transactions that occurred after the balance sheet date.
The  FASB  issued  ASU  No.  2010-09,  Subsequent  Events  (FASB  ASC  855),  Amendments  to  Certain  Recognition  and  Disclosure  Requirements,  on
February 24, 2010, in an effort to remove some contradictions between the requirements of U.S. GAAP and the SEC's filing rules. The amendments remove
the  requirement  that  public  companies  disclose  the  date  through  which  their  financial  statements  are  evaluated  for  subsequent  events  in  both  issued  and
revised financial statements. The Company has evaluated the period subsequent to December 31, 2011 for events that did not exist at the balance sheet date
but  arose  after  that  date  and  determined  that  no  subsequent  events  arose  that  should  be  disclosed  in  order  to  keep  the  financial  statements  from  being
misleading.

16. DISCLOSURE ABOUT OIL AND GAS PRODUCING ACTIVITIES (UNAUDITED):

The following information about the Company's oil and natural gas producing activities is presented in accordance with FASB ASC Topic 932, Oil and

Gas Reserve Estimation and Disclosures:

A.    OIL AND GAS RESERVES:

On January 6, 2010, the FASB issued an ASU updating oil and gas reserve estimation and disclosure requirements. The ASU amends FASB ASC 932
to align the reserve calculation and disclosure requirements with the requirements in SEC Release No. 33-8995. SEC Release No. 33-8995, amends oil and
gas reporting requirements under Rule 4-10 of Regulation S-X and Industry Guide 2 in Regulation S-K revising oil and gas reserves estimation and disclosure
requirements.  The  rules  include  changes  to  pricing  used  to  estimate  reserves,  the  ability  to  include  non-traditional  resources  in  reserves,  the  use  of  new
technology for determining reserves and permitting disclosure of probable and possible reserves. The primary objectives of the revisions are to increase the
transparency and information value of reserve disclosures and improve comparability among oil and gas companies.

ULTRA PETROLEUM CORP.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Our policies and practices regarding internal controls over the recording of reserves is structured to objectively and accurately estimate our oil and gas
reserves quantities and present values in compliance with the SEC's regulations and GAAP. The Vice President — Reservoir Engineering & Development is
primarily responsible for overseeing the preparation of the Company's reserve estimates by our independent engineers, Netherland, Sewell & Associates, Inc.
The  Vice  President  –  Reservoir  Engineering  &  Development  has  a  Bachelor  and  Master  of  Science  degree  in  Petroleum  Engineering  and  is  a  licensed
Professional Engineer with over 17 years of experience. The Company's internal controls over reserve estimates include reconciliation and review controls,
including an independent internal review of assumptions used in the estimation.

All  of  the  information  regarding  reserves  in  this  annual  report  is  derived  from  the  report  of  Netherland,  Sewell  &  Associates,  Inc.  The  report  of
Netherland,  Sewell  &  Associates,  Inc.  is  included  as  an  Exhibit  to  this  annual  report.  The  principal  engineer  at  Netherland,  Sewell  &  Associates,  Inc.
responsible for preparing our reserve estimates has a Bachelor of Science degree in Mechanical Engineering and is a licensed Professional Engineer with over
25 years of experience, including significant experience throughout the Rocky Mountain basins.

The Company's proved undeveloped reserves are limited to economic locations that are scheduled in accordance with the Company's current planning
and  budgeting  process.  The  inventory  of  bookable  locations  available  to  the  Company  is  substantially  larger  than  the  amount  ultimately  included  in  the
Company's  year-end  reserves.  From  time  to  time,  the  Company  may  adjust  the  inventory  and  schedule  of  its  proved  undeveloped  locations  in  response  to
changes in capital budget, economics, new opportunities in the portfolio or resource availability. The Company has not scheduled any proved undeveloped
reserves beyond five years nor does it have any proved undeveloped locations that have been part of its inventory of proved undeveloped locations for over
five years.

The  determination  of  oil  and  natural  gas  reserves  is  complex  and  highly  interpretive.  Assumptions  used  to  estimate  reserve  information  may
significantly  increase  or  decrease  such  reserves  in  future  periods.  The  estimates  of  reserves  are  subject  to  continuing  changes  and,  therefore,  an  accurate
determination of reserves may not be possible for many years because of the time needed for development, drilling, testing, and studies of reservoirs.

In  estimating  proved  reserves  and  future  revenue  as  of  December  31,  2011,  the  Company's  independent  reserve  engineer,  Netherland,  Sewell  &
Associates,  Inc.,  used  technical  and  economic  data  including,  but  not  limited  to,  well  logs,  geologic  maps,  seismic  data,  well  test  data,  production  data,
historical  price  and  cost  information  and  property  ownership  interests.  The  reserves  were  estimated  using  deterministic  methods;  these  estimates  were
prepared  in  accordance  with  generally  accepted  petroleum  engineering  and  evaluation  principles.  Standard  engineering  and  geoscience  methods,  such  as
performance  analysis,  volumetric  analysis  and  analogy,  that  were  considered  to  be  appropriate  and  necessary  to  establish  reserve  quantities  and  reserve
categorization  that  conform  to  SEC  definitions  and  guidelines,  were  also  used.  In  evaluating  the  information  at  their  disposal,  Netherland,  Sewell  &
Associates, Inc. excluded from their consideration all matters as to which the controlling interpretation may be legal or accounting, rather than engineering
and geoscience. As in all aspects of oil and natural gas evaluation, there are uncertainties inherent in the interpretation of engineering and geoscience data;
therefore, Netherland, Sewell & Associates, Inc.'s conclusions necessarily represent only informed professional judgment.

The following unaudited tables as of December 31, 2011, 2010, and 2009 are based upon estimates prepared by Netherland, Sewell & Associates, Inc.
in reports dated February 1, 2012, January 31, 2011, and January 27, 2010, respectively. These are estimated quantities of proved oil and natural gas reserves
for the Company and the changes in total proved reserves as of December 31, 2011, 2010 and 2009. All such reserves are located in the Green River Basin in
Wyoming and the Appalachian Basin of Pennsylvania.

C.    STANDARDIZED MEASURE:

ULTRA PETROLEUM CORP.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

The following table sets forth a standardized measure of the estimated discounted future net cash flows attributable to the Company's proved natural gas
reserves. Natural gas prices have fluctuated widely in recent years. The calculated weighted average sales prices utilized for the purposes of estimating the
Company's proved reserves and future net revenues at December 31, 2011, 2010 and 2009 was $4.035, $4.05 and $3.04 per Mcf, respectively, for natural gas
and $88.19, $68.93 and $52.18 per barrel, respectively, for condensate, based upon the average of the price in effect on the first day of the month for the
preceding twelve month period.

The  future  production  and  development  costs  represent  the  estimated  future  expenditures  to  be  incurred  in  developing  and  producing  the  proved
reserves,  assuming  continuation  of  existing  economic  conditions.  Future  income  tax  expense  was  computed  by  applying  statutory  income  tax  rates  to  the
difference  between  pretax  net  cash  flows  relating  to  the  Company's  proved  reserves  and  the  tax  basis  of  proved  properties  and  available  operating  loss
carryovers.

ULTRA PETROLEUM CORP.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

There  are  numerous  uncertainties  inherent  in  estimating  quantities  of  proved  reserves  and  projected  future  rates  of  production  and  timing  of
development expenditures, including many factors beyond the control of the Company. The reserve data and standardized measures set forth herein represent
only estimates. Reserve engineering is a subjective process of estimating underground accumulations of oil and natural gas that cannot be measured in an
exact  way  and  the  accuracy  of  any  reserve  estimate  is  a  function  of  the  quality  of  available  data  and  of  engineering  and  geological  interpretation  and
judgment. As a result, estimates of different engineers often vary. In addition, results of drilling, testing and production subsequent to the date of an estimate
may  justify  revision  of  such  estimates.  Accordingly,  reserve  estimates  are  often  different  from  the  quantities  of  oil  and  natural  gas  that  are  ultimately
recovered.  Further,  the  estimated  future  net  revenues  from  proved  reserves  and  the  present  value  thereof  are  based  upon  certain  assumptions,  including
geologic success, prices, future production levels and costs that may not prove correct over time. Predictions of future production levels are subject to great
uncertainty, and the meaningfulness of such estimates is highly dependent upon the accuracy of the assumptions upon which they are based. Historically, oil
and natural gas prices have fluctuated widely.

5. The registrant's other certifying officer and I have disclosed, based on our most recent evaluation of internal control over financial reporting, to the

registrant's auditors and the audit committee of registrant's board of directors (or persons performing the equivalent functions):

(a) All significant deficiencies and material weaknesses in the design or operation of internal control over financial reporting which are

reasonably likely to adversely affect the registrant's ability to record, process, summarize and report financial information; and

(b) Any fraud, whether or not material, that involves management or other employees who have a significant role in the registrant's internal

controls over financial reporting.

Mr. Brad Johnson
Ultra Petroleum Corporation
304 Inverness Way South, Suite 295
Englewood, Colorado 80112

Dear Mr. Johnson:

In accordance with your request, we have estimated the proved reserves and future revenue, as of December 31, 2011, to the Ultra Petroleum Corporation
(Ultra)  interest  in  certain  gas  properties  located  in  Pennsylvania  and  Wyoming.  We  completed  our  evaluation  on  or  about  the  date  of  this  letter.  It  is  our
understanding that the proved reserves estimated in this report constitute all of the proved reserves owned by Ultra. The estimates in this report have been
prepared in accordance with the definitions and regulations of the U.S. Securities and Exchange Commission (SEC) and, with the exception of the exclusion
of future income taxes, conform to the FASB Accounting Standards Codification Topic 932, Extractive Activities—Oil and Gas. Definitions are presented
immediately following this letter. This report has been prepared for Ultra's use in filing with the SEC; in our opinion the assumptions, data, methods, and
procedures used in the preparation of this report are appropriate for such purpose.

We estimate the net reserves and future net revenue to the Ultra interest in these properties, as of December 31, 2011, to be:

Gas volumes are expressed in millions of cubic feet (MMCF) at standard temperature and pressure bases. Condensate volumes are expressed in thousands of
barrels (MBBL); a barrel is equivalent to 42 United States gallons.

The estimates shown in this report are for proved reserves. As requested, probable and possible reserves that exist for these properties have not been included.
This report does not include any value that could be attributed to interests in undeveloped acreage beyond those tracts for which undeveloped reserves have
been estimated. Reserves categorization conveys the relative degree of certainty; reserves subcategorization is based on development and production status.
The estimates of reserves and future revenue included herein have not been adjusted for risk.

Gross revenue is Ultra's share of the gross (100 percent) revenue from the properties prior to any deductions. Future net revenue is after deductions for Ultra's
share of production taxes and ad valorem taxes, capital costs, abandonment costs, and operating expenses but before

consideration of any income taxes. The future net revenue has been discounted at an annual rate of 10 percent to determine its present worth, which is shown
to indicate the effect of time on the value of money. Future net revenue presented in this report, whether discounted or undiscounted, should not be construed
as being the fair market value of the properties.

Prices used in this report are based on the 12-month unweighted arithmetic average of the first-day-of-the-month price for each month in the period January
through December 2011. For gas volumes for the Wyoming properties, the average Kern River (Opal plant) spot price of $3.959 per MMBTU is adjusted for
energy content, fuel usage, and fees for gathering and processing. For gas volumes for the Pennsylvania properties, the average Dominion (South Point) spot
price  of  $4.243  per  MMBTU  is  adjusted  for  energy  content  and  fees  for  gathering  and  processing.  For  condensate  volumes,  the  average  West  Texas
Intermediate spot price of $96.19 per barrel is reduced by $8.00 to reflect contract adjustments for quality and fees for gathering and treating. All prices are
held constant throughout the lives of the properties. The average adjusted product prices weighted by production over the remaining lives of the properties are
$4.035 per MCF of gas and $88.19 per barrel of condensate.

Operating costs used in this report are based on operating expense records of Ultra. These costs include the per-well overhead expenses allowed under joint
operating agreements along with estimates of costs to be incurred at and below the district and field levels. Headquarters general and administrative overhead
expenses  of  Ultra  are  included  to  the  extent  that  they  are  covered  under  joint  operating  agreements  for  the  operated  properties.  Operating  costs  are  held
constant throughout the lives of the properties.

Capital costs used in this report were provided by Ultra and are based on authorizations for expenditure and actual costs from recent activity. Capital costs are
included as required for workovers, new development wells, and production equipment. Based on our understanding of Ultra's future development plans, a
review of the records provided to us, and our knowledge of similar properties, we regard these estimated capital costs to be reasonable. Abandonment costs
used in this report are Ultra's estimates of the costs to abandon the wells and production facilities, net of any salvage value. Capital costs and abandonment
costs are held constant to the date of expenditure.

For the purposes of this report, we did not perform any field inspection of the properties, nor did we examine the mechanical operation or condition of the
wells and facilities. We have not investigated possible environmental liability related to the properties; therefore, our estimates do not include any costs due to
such possible liability.

We have made no investigation of potential gas volume and value imbalances resulting from overdelivery or underdelivery to the Ultra interest. Therefore,
our  estimates  of  reserves  and  future  revenue  do  not  include  adjustments  for  the  settlement  of  any  such  imbalances;  our  projections  are  based  on  Ultra
receiving its net revenue interest share of estimated future gross gas production.

The reserves shown in this report are estimates only and should not be construed as exact quantities. Proved reserves are those quantities of oil and gas which,
by analysis of engineering and geoscience data, can be estimated with reasonable certainty to be economically producible. Estimates of reserves may increase
or decrease as a result of market conditions, future operations, changes in regulations,

 
 
 
or actual reservoir performance. In addition to the primary economic assumptions discussed herein, our estimates are based on certain assumptions including,
but not limited to, that the properties will be developed consistent with current development plans, that the properties will be operated in a prudent manner,
that  no  governmental  regulations  or  controls  will  be  put  in  place  that  would  impact  the  ability  of  the  interest  owner  to  recover  the  reserves,  and  that  our
projections  of  future  production  will  prove  consistent  with  actual  performance.  If  the  reserves  are  recovered,  the  revenues  therefrom  and  the  costs  related
thereto could be more or less than the estimated amounts. Because of governmental policies and uncertainties of supply and demand, the sales rates, prices
received for the reserves, and costs incurred in recovering such reserves may vary from assumptions made while preparing this report.

For  the  purposes  of  this  report,  we  used  technical  and  economic  data  including,  but  not  limited  to,  well  logs,  geologic  maps,  seismic  data,  well  test  data,
production data, historical price and cost information, and property ownership interests. The reserves in this report have been estimated using deterministic
methods; these estimates have been prepared in accordance with the Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information
promulgated by the Society of Petroleum Engineers (SPE Standards). We used standard engineering and geoscience methods, or a combination of methods,
including performance analysis, volumetric analysis, analogy, and reservoir modeling, that we considered to be appropriate and necessary to categorize and
estimate  reserves  in  accordance  with  SEC  definitions  and  regulations.  A  substantial  portion  of  these  reserves  are  for  non-producing  zones,  undeveloped
locations, and producing wells that lack sufficient production history upon which performance related estimates of reserves can be based; such reserves are
based on estimates of reservoir volumes and recovery efficiencies along with analogy to properties with similar geologic and reservoir characteristics. As in
all  aspects  of  oil  and  gas  evaluation,  there  are  uncertainties  inherent  in  the  interpretation  of  engineering  and  geoscience  data;  therefore,  our  conclusions
necessarily represent only informed professional judgment.

 
 
 
The  data  used  in  our  estimates  were  obtained  from  Ultra,  other  interest  owners,  various  operators  of  the  properties,  public  data  sources,  and  the
nonconfidential files of Netherland, Sewell & Associates, Inc. (NSAI) and were accepted as accurate. Supporting geoscience, performance, and work data are
on file in our office. The titles to the properties have not been examined by NSAI, nor has the actual degree or type of interest owned been independently
confirmed.  The  technical  persons  responsible  for  preparing  the  estimates  presented  herein  meet  the  requirements  regarding  qualifications,  independence,
objectivity, and confidentiality set forth in the SPE Standards. We are independent petroleum engineers, geologists, geophysicists, and petrophysicists; we do
not own an interest in these properties nor are we employed on a contingent basis.

DEFINITIONS OF OIL AND GAS RESERVES
Adapted from U.S. Securities and Exchange Commission Regulation S-X Section 210.4-10(a)

The  following  definitions  are  set  forth  in  U.S.  Securities  and  Exchange  Commission  (SEC)  Regulation  S-X  Section  210.4-10(a).  Also  included  is
supplemental  information  from  (1)  the  2007  Petroleum  Resources  Management  System  approved  by  the  Society  of  Petroleum  Engineers,  (2)  the  FASB
Accounting Standards Codification Topic 932, Extractive Activities—Oil and Gas, and (3) the SEC's Compliance and Disclosure Interpretations.

(1) Acquisition of properties.    Costs incurred to purchase, lease or otherwise acquire a property, including costs of lease bonuses and options to purchase or
lease properties, the portion of costs applicable to minerals when land including mineral rights is purchased in fee, brokers' fees, recording fees, legal costs,
and other costs incurred in acquiring properties.

(2)  Analogous  reservoir.        Analogous  reservoirs,  as  used  in  resources  assessments,  have  similar  rock  and  fluid  properties,  reservoir  conditions  (depth,
temperature,  and  pressure)  and  drive  mechanisms,  but  are  typically  at  a  more  advanced  stage  of  development  than  the  reservoir  of  interest  and  thus  may
provide  concepts  to  assist  in  the  interpretation  of  more  limited  data  and  estimation  of  recovery.  When  used  to  support  proved  reserves,  an  "analogous
reservoir" refers to a reservoir that shares the following characteristics with the reservoir of interest:

Same geological formation (but not necessarily in pressure communication with the reservoir of interest); 
(i)
Same environment of deposition; 
(ii)
(iii) Similar geological structure; and 
(iv) Same drive mechanism. 

Instruction to paragraph (a)(2): Reservoir properties must, in the aggregate, be no more favorable in the analog than in the reservoir of interest.

(3) Bitumen.    Bitumen, sometimes referred to as natural bitumen, is petroleum in a solid or semi-solid state in natural deposits with a viscosity greater than
10,000 centipoise measured at original temperature in the deposit and atmospheric pressure, on a gas free basis. In its natural state it usually contains sulfur,
metals, and other non-hydrocarbons.

(4) Condensate.    Condensate is a mixture of hydrocarbons that exists in the gaseous phase at original reservoir temperature and pressure, but that, when
produced, is in the liquid phase at surface pressure and temperature.

(5)  Deterministic  estimate.        The  method  of  estimating  reserves  or  resources  is  called  deterministic  when  a  single  value  for  each  parameter  (from  the
geoscience, engineering, or economic data) in the reserves calculation is used in the reserves estimation procedure.

(6) Developed oil and gas reserves.    Developed oil and gas reserves are reserves of any category that can be expected to be recovered:

(i)

(ii)

Through  existing  wells  with  existing  equipment  and  operating  methods  or  in  which  the  cost  of  the  required  equipment  is  relatively  minor
compared to the cost of a new well; and
Through  installed  extraction  equipment  and  infrastructure  operational  at  the  time  of  the  reserves  estimate  if  the  extraction  is  by  means  not
involving a well.

DEFINITIONS OF OIL AND GAS RESERVES
Adapted from U.S. Securities and Exchange Commission Regulation S-X Section 210.4-10(a)

Supplemental definitions from the 2007 Petroleum Resources Management System:

Developed Producing Reserves – Developed Producing Reserves are expected to be recovered from completion intervals that are open and producing at the time of the estimate. Improved
recovery reserves are considered producing only after the improved recovery project is in operation.

Developed Non-Producing Reserves – Developed Non-Producing Reserves include shut-in and behind-pipe Reserves. Shut-in Reserves are expected to be recovered from (1) completion
intervals which are open at the time of the estimate but which have not yet started producing, (2) wells which were shut-in for market conditions or pipeline connections, or (3) wells not
capable of production for mechanical reasons. Behind-pipe Reserves are expected to be recovered from zones in existing wells which will require additional completion work or future
recompletion prior to start of production. In all cases, production can be initiated or restored with relatively low expenditure compared to the cost of drilling a new well.

(7) Development costs.    Costs incurred to obtain access to proved reserves and to provide facilities for extracting, treating, gathering and storing the oil and
gas.  More  specifically,  development  costs,  including  depreciation  and  applicable  operating  costs  of  support  equipment  and  facilities  and  other  costs  of
development activities, are costs incurred to:

(i)

Gain access to and prepare well locations for drilling, including surveying well locations for the purpose of determining specific development
drilling  sites,  clearing  ground,  draining,  road  building,  and  relocating  public  roads,  gas  lines,  and  power  lines,  to  the  extent  necessary  in
developing the proved reserves.

(ii) Drill and equip development wells, development-type stratigraphic test wells, and service wells, including the costs of platforms and of well

equipment such as casing, tubing, pumping equipment, and the wellhead assembly.

(iii) Acquire, construct, and install production facilities such as lease flow lines, separators, treaters, heaters, manifolds, measuring devices, and

production storage tanks, natural gas cycling and processing plants, and central utility and waste disposal systems.

(iv) Provide improved recovery systems. 

(8)  Development  project.        A  development  project  is  the  means  by  which  petroleum  resources  are  brought  to  the  status  of  economically  producible.  As
examples, the development of a single reservoir or field, an incremental development in a producing field, or the integrated development of a group of several
fields and associated facilities with a common ownership may constitute a development project.

(9) Development well.    A well drilled within the proved area of an oil or gas reservoir to the depth of a stratigraphic horizon known to be productive.

(10) Economically producible.    The term economically producible, as it relates to a resource, means a resource which generates revenue that exceeds, or is
reasonably expected to exceed, the costs of the operation. The value of the products that generate revenue shall be determined at the terminal point of oil and
gas producing activities as defined in paragraph (a)(16) of this section.

(11) Estimated ultimate recovery (EUR). Estimated ultimate recovery is the sum of reserves remaining as of a given date and cumulative production as of that
date.

(12)  Exploration  costs.        Costs  incurred  in  identifying  areas  that  may  warrant  examination  and  in  examining  specific  areas  that  are  considered  to  have
prospects of containing oil and gas reserves, including costs of drilling exploratory wells and exploratory-type stratigraphic test wells. Exploration costs may
be incurred both before

acquiring the related property (sometimes referred to in part as prospecting costs) and after acquiring the property. Principal types of exploration costs, which
include depreciation and applicable operating costs of support equipment and facilities and other costs of exploration activities, are:

(i)

Costs of topographical, geographical and geophysical studies, rights of access to properties to conduct those studies, and salaries and other
expenses of geologists, geophysical crews, and others conducting those studies. Collectively, these are sometimes referred to as geological and
geophysical or "G&G" costs.

(ii) Costs of carrying and retaining undeveloped properties, such as delay rentals, ad valorem taxes on properties, legal costs for title defense, and

the maintenance of land and lease records.

(iii) Dry hole contributions and bottom hole contributions. 
(iv) Costs of drilling and equipping exploratory wells. 
(v)

Costs of drilling exploratory-type stratigraphic test wells. 

(13) Exploratory well.    An exploratory well is a well drilled to find a new field or to find a new reservoir in a field previously found to be productive of oil or
gas in another reservoir. Generally, an exploratory well is any well that is not a development well, an extension well, a service well, or a stratigraphic test well
as those items are defined in this section.

(14) Extension well.    An extension well is a well drilled to extend the limits of a known reservoir.

(15) Field.    An area consisting of a single reservoir or multiple reservoirs all grouped on or related to the same individual geological structural feature and/or
stratigraphic condition. There may be two or more reservoirs in a field which are separated vertically by intervening impervious strata, or laterally by local
geologic barriers, or by both. Reservoirs that are associated by being in overlapping or adjacent fields may be treated as a single or common operational field.
The geological terms "structural feature" and "stratigraphic condition" are intended to identify localized geological features as opposed to the broader terms of
basins, trends, provinces, plays, areas-of-interest, etc.

(16) Oil and gas producing activities.

(i)

Oil and gas producing activities include: 

(A) The search for crude oil, including condensate and natural gas liquids, or natural gas ("oil and gas") in their natural states and

original locations;

(B) The acquisition of property rights or properties for the purpose of further exploration or for the purpose of removing the oil or gas

from such properties;

(C) The construction, drilling, and production activities necessary to retrieve oil and gas from their natural reservoirs, including the

acquisition, construction, installation, and maintenance of field gathering and storage systems, such as:
(1)
(2) Gathering, treating, and field processing (as in the case of processing gas to extract liquid hydrocarbons); and 

Lifting the oil and gas to the surface; and 

(D) Extraction of saleable hydrocarbons, in the solid, liquid, or gaseous state, from oil sands, shale, coalbeds, or other nonrenewable
natural  resources  which  are  intended  to  be  upgraded  into  synthetic  oil  or  gas,  and  activities  undertaken  with  a  view  to  such
extraction.

Instruction 1 to paragraph (a)(16)(i): The oil and gas production function shall be regarded as ending at a "terminal point", which is the outlet valve on
the lease or field storage tank. If unusual physical or operational circumstances exist, it may be appropriate to regard the terminal point for the production
function as:

a.

The first point at which oil, gas, or gas liquids, natural or synthetic, are delivered to a main pipeline, a common carrier, a refinery, or a marine
terminal; and

DEFINITIONS OF OIL AND GAS RESERVES
Adapted from U.S. Securities and Exchange Commission Regulation S-X Section 210.4-10(a)

b.

In the case of natural resources that are intended to be upgraded into synthetic oil or gas, if those natural resources are delivered to a purchaser
prior  to  upgrading,  the  first  point  at  which  the  natural  resources  are  delivered  to  a  main  pipeline,  a  common  carrier,  a  refinery,  a  marine
terminal, or a facility which upgrades such natural resources into synthetic oil or gas.

Instruction 2 to paragraph (a)(16)(i): For purposes of this paragraph (a)(16), the term saleable hydrocarbons means hydrocarbons that are saleable in the
state in which the hydrocarbons are delivered.

(ii) Oil and gas producing activities do not include: 

(A) Transporting, refining, or marketing oil and gas; 
(B)

Processing of produced oil, gas, or natural resources that can be upgraded into synthetic oil or gas by a registrant that does not
have the legal right to produce or a revenue interest in such production;

(C) Activities relating to the production of natural resources other than oil, gas, or natural resources from which synthetic oil and gas

can be extracted; or
Production of geothermal steam. 

(D)

(17) Possible reserves.    Possible reserves are those additional reserves that are less certain to be recovered than probable reserves.

(i) When deterministic methods are used, the total quantities ultimately recovered from a project have a low probability of exceeding proved plus
probable  plus  possible  reserves.  When  probabilistic  methods  are  used,  there  should  be  at  least  a  10%  probability  that  the  total  quantities
ultimately recovered will equal or exceed the proved plus probable plus possible reserves estimates.
Possible reserves may be assigned to areas of a reservoir adjacent to probable reserves where data control and interpretations of available data
are progressively less certain. Frequently, this will be in areas where geoscience and engineering data are unable to define clearly the area and
vertical limits of commercial production from the reservoir by a defined project.

(ii)

(iii) Possible  reserves  also  include  incremental  quantities  associated  with  a  greater  percentage  recovery  of  the  hydrocarbons  in  place  than  the

recovery quantities assumed for probable reserves.

(v)

(iv) The proved plus probable and proved plus probable plus possible reserves estimates must be based on reasonable alternative technical and
commercial interpretations within the reservoir or subject project that are clearly documented, including comparisons to results in successful
similar projects.
Possible reserves may be assigned where geoscience and engineering data identify directly adjacent portions of a reservoir within the same
accumulation  that  may  be  separated  from  proved  areas  by  faults  with  displacement  less  than  formation  thickness  or  other  geological
discontinuities and that have not been penetrated by a wellbore, and the registrant believes that such adjacent portions are in communication
with  the  known  (proved)  reservoir.  Possible  reserves  may  be  assigned  to  areas  that  are  structurally  higher  or  lower  than  the  proved  area  if
these areas are in communication with the proved reservoir.

(vi) Pursuant to paragraph (a)(22)(iii) of this section, where direct observation has defined a highest known oil (HKO) elevation and the potential
exists for an associated gas cap, proved oil reserves should be assigned in the structurally higher portions of the reservoir above the HKO only
if the higher contact can be established with reasonable certainty through reliable technology. Portions of the reservoir that do not meet this
reasonable certainty criterion may be assigned as probable and possible oil or gas based on reservoir fluid properties and pressure gradient
interpretations.

(18) Probable reserves.    Probable reserves are those additional reserves that are less certain to be recovered than proved reserves but which, together with
proved reserves, are as likely as not to be recovered.

(i) When deterministic methods are used, it is as likely as not that actual remaining quantities recovered will exceed the sum of estimated proved
plus probable reserves. When probabilistic methods are used, there should be at least a 50% probability that the actual quantities recovered
will equal or exceed the proved plus probable reserves estimates.
Probable reserves may be assigned to areas of a reservoir adjacent to proved reserves where data control or interpretations of available data are
less certain, even if the interpreted reservoir continuity of structure or productivity does not meet the reasonable certainty criterion. Probable
reserves  may  be  assigned  to  areas  that  are  structurally  higher  than  the  proved  area  if  these  areas  are  in  communication  with  the  proved
reservoir.

(ii)

(iii) Probable reserves estimates also include potential incremental quantities associated with a greater percentage recovery of the hydrocarbons in

place than assumed for proved reserves.

(iv) See also guidelines in paragraphs (a)(17)(iv) and (a)(17)(vi) of this section. 

(19) Probabilistic estimate.    The method of estimation of reserves or resources is called probabilistic when the full range of values that could reasonably
occur  for  each  unknown  parameter  (from  the  geoscience  and  engineering  data)  is  used  to  generate  a  full  range  of  possible  outcomes  and  their  associated
probabilities of occurrence.

(20) Production costs.

(i)

Costs  incurred  to  operate  and  maintain  wells  and  related  equipment  and  facilities,  including  depreciation  and  applicable  operating  costs  of
support equipment and facilities and other costs of operating and maintaining those wells and related equipment and facilities. They become
part of the cost of oil and gas produced. Examples of production costs (sometimes called lifting costs) are:

(A) Costs of labor to operate the wells and related equipment and facilities. 
(B) Repairs and maintenance. 
(C) Materials, supplies, and fuel consumed and supplies utilized in operating the wells and related equipment and facilities. 
(D)
(E)

Property taxes and insurance applicable to proved properties and wells and related equipment and facilities. 
Severance taxes. 

(ii)

Some support equipment or facilities may serve two or more oil and gas producing activities and may also serve transportation, refining, and
marketing activities. To the extent that the support equipment and facilities are used in oil and gas producing activities, their depreciation and
applicable operating costs become exploration, development or production costs, as appropriate. Depreciation, depletion, and amortization of
capitalized acquisition, exploration, and development costs are not production costs but also become part of the cost of oil and gas produced
along with production (lifting) costs identified above.

(21) Proved area.    The part of a property to which proved reserves have been specifically attributed.

(22) Proved oil and gas reserves.    Proved oil and gas reserves are those quantities of oil and gas, which, by analysis of geoscience and engineering data, can
be  estimated  with  reasonable  certainty  to  be  economically  producible—from  a  given  date  forward,  from  known  reservoirs,  and  under  existing  economic
conditions, operating methods, and government regulations—prior to the time at which contracts providing the right to operate expire,

unless  evidence  indicates  that  renewal  is  reasonably  certain,  regardless  of  whether  deterministic  or  probabilistic  methods  are  used  for  the  estimation.  The
project to extract the hydrocarbons must have commenced or the operator must be reasonably certain that it will commence the project within a reasonable
time.

(i)

The area of the reservoir considered as proved includes: 

(A) The area identified by drilling and limited by fluid contacts, if any, and 
(B) Adjacent undrilled portions of the reservoir that can, with reasonable certainty, be judged to be continuous with it and to contain

economically producible oil or gas on the basis of available geoscience and engineering data.

(ii)

In the absence of data on fluid contacts, proved quantities in a reservoir are limited by the lowest known hydrocarbons (LKH) as seen in a well
penetration unless geoscience, engineering, or performance data and reliable technology establishes a lower contact with reasonable certainty.
(iii) Where direct observation from well penetrations has defined a highest known oil (HKO) elevation and the potential exists for an associated
gas  cap,  proved  oil  reserves  may  be  assigned  in  the  structurally  higher  portions  of  the  reservoir  only  if  geoscience,  engineering,  or
performance data and reliable technology establish the higher contact with reasonable certainty.

(iv) Reserves  which  can  be  produced  economically  through  application  of  improved  recovery  techniques  (including,  but  not  limited  to,  fluid

injection) are included in the proved classification when:

(A)

Successful testing by a pilot project in an area of the reservoir with properties no more favorable than in the reservoir as a whole,
the  operation  of  an  installed  program  in  the  reservoir  or  an  analogous  reservoir,  or  other  evidence  using  reliable  technology
establishes the reasonable certainty of the engineering analysis on which the project or program was based; and
(B) The project has been approved for development by all necessary parties and entities, including governmental entities. 

(v)

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

(23) Proved properties.    Properties with proved reserves.

(24) Reasonable certainty.    If deterministic methods are used, reasonable certainty means a high degree of confidence that the quantities will be recovered. If
probabilistic  methods  are  used,  there  should  be  at  least  a  90%  probability  that  the  quantities  actually  recovered  will  equal  or  exceed  the  estimate.  A  high
degree of confidence exists if the quantity is much more likely to be achieved than not, and, as changes due to increased availability of geoscience (geological,
geophysical, and geochemical), engineering, and economic data are made to estimated ultimate recovery (EUR) with time, reasonably certain EUR is much
more likely to increase or remain constant than to decrease.

(25) Reliable technology.    Reliable technology is a grouping of one or more technologies (including computational methods) that has been field tested and
has been demonstrated to provide reasonably certain results with consistency and repeatability in the formation being evaluated or in an analogous formation.

(26) Reserves.    Reserves are estimated remaining quantities of oil and gas and related substances anticipated to be economically producible, as of a given
date, by application of development projects to known accumulations. In addition, there must exist, or there must be a reasonable expectation that there will
exist,  the  legal  right  to  produce  or  a  revenue  interest  in  the  production,  installed  means  of  delivering  oil  and  gas  or  related  substances  to  market,  and  all
permits and financing required to implement the project.

DEFINITIONS OF OIL AND GAS RESERVES
Adapted from U.S. Securities and Exchange Commission Regulation S-X Section 210.4-10(a)

Note  to  paragraph  (a)(26):  Reserves  should  not  be  assigned  to  adjacent  reservoirs  isolated  by  major,  potentially  sealing,  faults  until  those  reservoirs  are
penetrated and evaluated as economically producible. Reserves should not be assigned to areas that are clearly separated from a known accumulation by a
non-productive  reservoir  (i.e.,  absence  of  reservoir,  structurally  low  reservoir,  or  negative  test  results).  Such  areas  may  contain  prospective  resources  (i.e.,
potentially recoverable resources from undiscovered accumulations).

Excerpted from the FASB Accounting Standards Codification Topic 932, Extractive Activities—Oil and Gas:

932-235-50-30 A standardized measure of discounted future net cash flows relating to an entity's interests in both of the following shall be disclosed as of the end of the year:

a.
b.

Proved oil and gas reserves (see paragraphs 932-235-50-3 through 50-11B) 
Oil and gas subject to purchase under long-term supply, purchase, or similar agreements and contracts in which the entity participates in the operation of the properties
on which the oil or gas is located or otherwise serves as the producer of those reserves (see paragraph 932-235-50-7).

The standardized measure of discounted future net cash flows relating to those two types of interests in reserves may be combined for reporting purposes.

932-235-50-31 All of the following information shall be disclosed in the aggregate and for each geographic area for which reserve quantities are disclosed in accordance with paragraphs
932-235-50-3 through 50-11B:

a.

b.

c.

d.
e.

f.

Future cash inflows.    These shall be computed by applying prices used in estimating the entity's proved oil and gas reserves to the year-end quantities of those reserves.
Future price changes shall be considered only to the extent provided by contractual arrangements in existence at year-end.
Future development and production costs.    These costs shall be computed by estimating the expenditures to be incurred in developing and producing the proved oil and
gas  reserves  at  the  end  of  the  year,  based  on  year-end  costs  and  assuming  continuation  of  existing  economic  conditions.  If  estimated  development  expenditures  are
significant, they shall be presented separately from estimated production costs.
Future income tax expenses.    These expenses shall be computed by applying the appropriate year-end statutory tax rates, with consideration of future tax rates already
legislated,  to  the  future  pretax  net  cash  flows  relating  to  the  entity's  proved  oil  and  gas  reserves,  less  the  tax  basis  of  the  properties  involved.  The  future  income  tax
expenses shall give effect to tax deductions and tax credits and allowances relating to the entity's proved oil and gas reserves.
Future net cash flows.    These amounts are the result of subtracting future development and production costs and future income tax expenses from future cash inflows. 
Discount. This amount shall be derived from using a discount rate of 10 percent a year to reflect the timing of the future net cash flows relating to proved oil and gas
reserves.
Standardized measure of discounted future net cash flows.    This amount is the future net cash flows less the computed discount. 

(27)  Reservoir.        A  porous  and  permeable  underground  formation  containing  a  natural  accumulation  of  producible  oil  and/or  gas  that  is  confined  by
impermeable rock or water barriers and is individual and separate from other reservoirs.

(28) Resources.    Resources are quantities of oil and gas estimated to exist in naturally occurring accumulations. A portion of the resources may be estimated
to be recoverable, and another portion may be considered to be unrecoverable. Resources include both discovered and undiscovered accumulations.

(29) Service well.    A well drilled or completed for the purpose of supporting production in an existing field. Specific purposes of service wells include gas
injection, water injection, steam injection, air injection, salt-water disposal, water supply for injection, observation, or injection for in-situ combustion.

(30)  Stratigraphic  test  well.        A  stratigraphic  test  well  is  a  drilling  effort,  geologically  directed,  to  obtain  information  pertaining  to  a  specific  geologic
condition.  Such  wells  customarily  are  drilled  without  the  intent  of  being  completed  for  hydrocarbon  production.  The  classification  also  includes  tests
identified  as  core  tests  and  all  types  of  expendable  holes  related  to  hydrocarbon  exploration.  Stratigraphic  tests  are  classified  as  "exploratory  type"  if  not
drilled in a known area or "development type" if drilled in a known area.

(31) Undeveloped oil and gas reserves.    Undeveloped oil and gas reserves are reserves of any category that are expected to be recovered from new wells on
undrilled acreage, or from existing wells where a relatively major expenditure is required for recompletion.

(i)

Reserves on undrilled acreage shall be limited to those directly offsetting development spacing areas that are reasonably certain of production
when  drilled,  unless  evidence  using  reliable  technology  exists  that  establishes  reasonable  certainty  of  economic  producibility  at  greater
distances.

(ii) Undrilled  locations  can  be  classified  as  having  undeveloped  reserves  only  if  a  development  plan  has  been  adopted  indicating  that  they  are

scheduled to be drilled within five years, unless the specific circumstances, justify a longer time.

From the SEC's Compliance and Disclosure Interpretations (October 26, 2009):

Although several types of projects — such as constructing offshore platforms and development in urban areas, remote locations or environmentally sensitive locations — by their nature
customarily take a longer time to develop and therefore often do justify longer time periods, this determination must always take into consideration all of the facts and circumstances. No
particular type of project per se justifies a longer time period, and any extension beyond five years should be the exception, and not the rule.

Factors that a company should consider in determining whether or not circumstances justify recognizing reserves even though development may extend past five years include, but are not
limited to, the following:

generally would not constitute significant development activities);

 • The  company's  level  of  ongoing  significant  development  activities  in  the  area  to  be  developed  (for  example,  drilling  only  the  minimum  number  of  wells  necessary  to  maintain  the  lease
  •   The company's historical record at completing development of comparable long-term projects;
 •  The amount of time in which the company has maintained the leases, or booked the reserves, without significant development activities;
 • The extent to which the company has followed a previously adopted development plan (for example, if a company has changed its development plan several times without taking significant
 • The extent to which delays in development are caused by external factors related to the physical operating environment (for example, restrictions on development on Federal lands, but not

steps to implement any of those plans, recognizing proved undeveloped reserves typically would not be appropriate); and

obtaining government permits), rather than by internal factors (for example, shifting resources to develop properties with higher priority).

(iii) Under no circumstances shall estimates for undeveloped reserves be attributable to any acreage for which an application of fluid injection or
other improved recovery technique is contemplated, unless such techniques have been proved effective by actual projects in the same reservoir
or an analogous reservoir, as defined in paragraph (a)(2) of this section, or by other evidence using reliable technology establishing reasonable
certainty.

(32) Unproved properties.    Properties with no proved reserves.
