The Company uses a valuation framework based upon inputs that
market participants use in pricing an asset or liability, which
are classified into two categories: observable inputs and
unobservable inputs. Observable inputs represent market data
obtained from independent sources, whereas unobservable inputs
reflect a company’s own market assumptions, which are used
if observable inputs are not reasonably available without undue
cost and effort. These two types of inputs are further
prioritized into the following fair value input hierarchy:

<td align="left">
Unadjusted quoted prices in active markets that are accessible
at the measurement date for identical, unrestricted assets or
liabilities. The Company considers active markets to be those in
which transactions for the assets or liabilities occur in
sufficient frequency and volume to provide pricing information
on an ongoing basis.

</td>
<td align="left">
Quoted prices in markets that are not active, or inputs which
are observable, either directly or indirectly, for substantially
the full term of the asset or liability. This category includes
those derivative instruments that the Company values using
observable market data. Substantially all of these inputs are
observable in the marketplace throughout the full term of the
derivative instrument, can be derived from observable data, or
supported by observable levels at which transactions are
executed in the marketplace. Level 2 instruments primarily
include non-exchange traded derivatives such as
<font style="white-space: nowrap">over-the-counter</font>
commodity price swaps, basis swaps, investments and interest
rate swaps. The Company’s valuation models are primarily
industry-standard models that consider various inputs including:
(i) quoted forward prices for commodities, (ii) time
value and (iii) current market and contractual prices for
the underlying instruments, as well as other relevant economic
measures. The Company utilizes its counterparties’
valuations to assess the reasonableness of its prices and
valuation techniques.

<td align="left">
Measured based on prices or valuation models that require inputs
that are both significant to the fair value measurement and less
observable from objective sources (<i>i.e.</i>, supported by
little or no market activity). Level 3 instruments
primarily include derivative instruments, such as commodity
price collars and floors, as well as investments. The
Company’s valuation models are primarily industry-standard
models that consider various inputs including: (i) quoted
forward prices for commodities, (ii) time value,
(iii) volatility factors and (iv) current market and
contractual prices for the underlying instruments, as well as
other relevant economic measures. Although the Company utilizes
its counterparties’ valuations to assess the reasonableness
of our prices and valuation techniques, the Company does not
have sufficient corroborating market evidence to support
classifying these assets and liabilities as Level 2.

<i>Derivative instruments.</i>  The fair value of the
Company’s derivative instruments are estimated by
management considering various factors, including closing
exchange and
<font style="white-space: nowrap">over-the-counter</font>
quotations and the time value of the underlying commitments.
Financial assets and liabilities are classified based on the
lowest level of input that is significant to the fair value
measurement. The Company’s assessment of the significance
of a particular input to the fair value measurement requires
judgment, and may affect the valuation of the fair value of
assets and liabilities and their placement within the fair value
hierarchy levels. The following table (i) summarizes the
valuation of each of the Company’s financial instruments by
required pricing levels and (ii) summarizes the gross fair
value by the
appropriate balance sheet classification, even when the
derivative instruments are subject to netting arrangements and
qualify for net presentation in the Company’s consolidated
balance sheets at December 31, 2010 and 2009:

<i>Impairments of long-lived assets</i> — The Company
reviews its long-lived assets to be held and used, including
proved oil and natural gas properties, whenever events or
circumstances indicate that the carrying value of those assets
may not be recoverable. An impairment loss is indicated if the
sum of the expected undiscounted future net cash flows is less
than the carrying amount of the assets. In this circumstance,
the Company recognizes an impairment loss for the amount by
which the carrying amount of the asset exceeds the estimated
fair value of the asset. The Company reviews its oil and natural
gas properties by amortization base or by individual well for
those wells not constituting part of an amortization base. For
each property determined to be impaired, an impairment loss
equal to the difference between the carrying value of the
properties and the estimated fair value (discounted future cash
flows) of the properties would be recognized at that time.
Estimating future cash flows involves the use of judgments,
including estimation of the proved and unproved oil and natural
gas reserve quantities, timing of development and production,
expected future commodity prices, capital expenditures and
production costs.

The Company periodically reviews its proved oil and natural gas
properties that are sensitive to oil and natural gas prices for
impairment. Impairment expense is caused primarily due to
declines in commodity prices and well performance. The following
table reports the carrying amounts, estimated fair values and
impairment expense of long-lived assets for continuing and
discontinued operations for the years ended December 31,

<i>Asset Retirement Obligations</i> — The Company
estimates the fair value of Asset Retirement Obligations
(“AROs”) based on discounted cash flow projections
using numerous estimates, assumptions and judgments
regarding such factors as the existence of a legal obligation
for an ARO; amounts and timing of settlements; the
credit-adjusted risk-free rate to be used; and inflation rates.
See Note E for a summary of changes in AROs.
