<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>1. Basis of Consolidation and Presentation</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The interim unaudited consolidated financial statements include the accounts of Patterson-UTI
Energy, Inc. (the &#147;Company&#148;) and its wholly-owned subsidiaries. All significant intercompany
accounts and transactions have been eliminated. The Company has no controlling financial interests
in any entity that is not a wholly-owned subsidiary and which would require consolidation.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The interim consolidated financial statements have been prepared by management of the Company,
without audit, pursuant to the rules and regulations of the Securities and Exchange Commission.
Certain information and footnote disclosures normally included in financial statements prepared in
accordance with accounting principles generally accepted in the United States of America have been
omitted pursuant to such rules and regulations, although the Company believes the disclosures
included either on the face of the financial statements or herein are sufficient to make the
information presented not misleading. In the opinion of management, all adjustments which are of a
normal recurring nature considered necessary for a fair statement of the information in conformity
with accounting principles generally accepted in the United States have been included. The
Unaudited Consolidated Balance Sheet as of December&nbsp;31, 2007, as presented herein, was derived from
the audited balance sheet of the Company, but does not include all disclosures required by
accounting principles generally accepted in the United States of America. These unaudited
consolidated financial statements should be read in conjunction with the consolidated financial
statements and related notes included in the Company&#146;s Annual Report on Form 10-K for the fiscal
year ended December&nbsp;31, 2007.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The U.S. dollar is the functional currency for all of the Company&#146;s operations except for its
Canadian operations, which use the Canadian dollar as their functional currency. The effects of
exchange rate changes are reflected in accumulated other comprehensive income, which is a separate
component of stockholders&#146; equity.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company provides a dual presentation of its net income per common share in its Unaudited
Consolidated Statements of Income: Basic net income per common share (&#147;Basic EPS&#148;) and diluted net
income per common share (&#147;Diluted EPS&#148;). Basic EPS excludes dilution and is computed by dividing
net income by the weighted average number of common shares outstanding during the period excluding
nonvested restricted stock. Diluted EPS is based on the weighted-average number of common shares
outstanding plus the impact of dilutive instruments, including stock options, restricted stock and
stock unit awards using the treasury stock method. The following table presents information
necessary to calculate net income per share for the three and six months ended June&nbsp;30, 2008 and
2007 as well as potentially dilutive securities excluded from the weighted average number of
diluted common shares outstanding, as their inclusion would have been anti-dilutive during the
three and six months ended June&nbsp;30, 2008 and 2007 (in thousands, except per share amounts):

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company recognizes the cost of share-based awards under the fair-value method. The
Company uses share-based awards to compensate employees and non-employee directors. All awards
have been equity instruments in the form of stock options, restricted stock awards and stock unit
awards and have included both service and, in certain cases, performance conditions. The Company
issues shares of common stock when vested stock option awards are exercised, when restricted stock
awards are granted and when stock unit awards vest.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>Stock Options. </I>The Company estimates the grant date fair values of stock options using the
Black-Scholes-Merton valuation model (&#147;Black-Scholes&#148;). Volatility assumptions are based on the
historic volatility of the Company&#146;s common stock over the most recent period equal to the expected
term of the options as of the date the options are granted. The expected term assumptions are
based on the Company&#146;s experience with respect to employee stock option activity. Dividend yield
assumptions are based on the expected dividends at the time the options are granted. The risk-free
interest rate assumptions are determined by reference to United States Treasury yields.
Weighted-average assumptions used to estimate the grant date fair values for stock options granted
in the three and six-month periods ended June&nbsp;30, 2008 and 2007 follow:

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company&#146;s revenues, operating profits and identifiable assets are primarily attributable
to four business segments: (i)&nbsp;contract drilling of oil and natural gas wells, (ii)&nbsp;pressure
pumping services, (iii)&nbsp;drilling and completion fluid services and (iv)&nbsp;the investment, on a
working interest basis, in oil and natural gas properties. Each of these segments represents a
distinct type of business based upon the type and nature of services and products offered. These
segments have separate management teams which report to the Company&#146;s chief operating decision
maker and have distinct and identifiable revenues and expenses. Separate financial data for each
of our four business segments is provided in the table below (in thousands):

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company has an unsecured revolving line of credit (&#147;LOC&#148;) with a maximum borrowing
capacity of $375&nbsp;million. Interest is paid on outstanding LOC balances at a floating rate ranging
from LIBOR plus 0.625% to 1.0% or the prime rate at the Company&#146;s election. Any outstanding
borrowings must be repaid at maturity on December&nbsp;16, 2009. This arrangement includes various
fees, including a commitment fee on the average daily unused amount (0.15% at June&nbsp;30, 2008).
There are customary restrictions and covenants associated with the LOC. Financial covenants
provide for a maximum debt to capitalization ratio and a minimum interest coverage ratio. The
Company does not expect that the restrictions and covenants will impact its ability to operate or
react to opportunities that might arise. As of June&nbsp;30, 2008, the Company had no borrowings
outstanding under the LOC. However, the Company had $58.6&nbsp;million in letters of credit outstanding
and as a result, the Company had available borrowing capacity of approximately $316&nbsp;million at June
30, 2008.

underlying insurance contracts. These letters of credit expire at various times during the

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On July&nbsp;30, 2008, the Company&#146;s Board of Directors approved a cash dividend on its common
stock in the amount of $0.16 per share to be paid on September&nbsp;30, 2008 to holders of record as of
September&nbsp;12, 2008. The amount and timing of all future dividend payments, if any, is subject to
the discretion of the Board of Directors and will depend upon business conditions, results of
operations, financial condition, terms of the Company&#146;s credit facilities and other factors.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On August&nbsp;1, 2007, the Company&#146;s Board of Directors approved a stock buyback program
(&#147;Program&#148;), authorizing purchases of up to $250&nbsp;million of the Company&#146;s common stock in open
market or privately negotiated transactions. As of June&nbsp;30, 2008, the Company had authority
remaining under the Program to purchase approximately $180&nbsp;million of the Company&#146;s outstanding
common stock. Shares purchased under the Program are accounted for as treasury stock.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company purchased 151,794 shares of treasury stock from employees during the six months
ended June&nbsp;30, 2008 to provide employees with the funds necessary to satisfy payroll tax
withholding obligations upon the vesting of shares of restricted stock. The purchases were made at
fair market value and the total purchase price for these shares was approximately $4.5&nbsp;million.
These purchases were made pursuant to the terms of the Patterson-UTI Energy, Inc. 2005 Long-Term
Incentive Plan and not pursuant to the Program.

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company adopted Financial Accounting Standards Board (&#147;FASB&#148;) Interpretation No.&nbsp;48,
<I>Accounting for Uncertainty in Income Taxes &#150; an interpretation of FASB Statement No.&nbsp;109 </I>(&#147;FIN 48&#148;)
on January&nbsp;1, 2007. FIN 48 clarifies the accounting for uncertainty in income taxes recognized in
an enterprise&#146;s financial statements and prescribes a recognition threshold and measurement
attribute for the financial statement recognition and measurement of a tax position taken or
expected to be taken in a tax return. As of June&nbsp;30, 2008, the Company had no unrecognized tax
benefits. In connection with the adoption of FIN 48, the Company established a policy to account
for interest and penalties with respect to income taxes as operating expenses. As of June&nbsp;30,
2008, the tax years ended December&nbsp;31, 2004 through December&nbsp;31, 2007 are open for examination by
U.S. taxing authorities. As of June&nbsp;30, 2008, the tax years ended December&nbsp;31, 2003 through
December&nbsp;31, 2007 are open for examination by Canadian taxing authorities.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In September&nbsp;2006, the FASB issued Statement No.&nbsp;157, <I>Fair Value Measurements </I>(&#147;FAS 157&#148;).
FAS 157 defines fair value, establishes a framework for measuring fair value in generally accepted
accounting principles, and expands disclosures about fair value measurement. The initial
application of FAS 157 is limited to financial assets and liabilities and became effective on
January&nbsp;1, 2008 for the Company. The impact of the initial application was not material. The
Company will adopt FAS 157 on a prospective basis for nonfinancial assets and liabilities that are
not measured at fair value on a recurring basis on January&nbsp;1, 2009. The application of FAS 157 to
the Company&#146;s nonfinancial assets and liabilities will primarily be limited to assets acquired and
liabilities assumed in a business combination, asset retirement obligations and asset impairments,
including goodwill and long-lived assets. This application of FAS 157 is not expected to have a
material impact to the Company.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In June&nbsp;2008, the FASB issued FASB Staff Position No.&nbsp;EITF 03-6-1, <I>Determining Whether
Instruments Granted in Share-Based Payment Transactions Are Participating Securities </I>(&#147;FSP EITF
03-6-1&#148;). FSB EITF 03-6-1 clarifies that share-based payment awards that entitle their holders to
receive nonforfeitable dividends before vesting should be considered participating securities and,
as such, should be included in the calculation of basic earnings-per-share using the two-class
method. Certain of the Company&#146;s share-based payment awards entitle the holders to receive
nonforfeitable dividends and the application of the provisions of FSP EITF 03-6-1 may have the
effect of reducing basic and diluted earnings-per-share by an immaterial amount. FSP EITF 03-6-1
is effective for financial statements issued for fiscal years beginning after December&nbsp;15, 2008, as
well as interim periods within those years. Once effective, all prior-period earnings-per-share
data presented must be adjusted retrospectively to conform with the provisions of the FSP. The FSP
will be effective for the Company beginning in the quarter ending March&nbsp;31, 2009 and early
application is not permitted.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We provide our contract services to oil and natural gas operators in many of the oil and
natural gas producing regions of North America. Our contract drilling operations are focused in
various regions of Texas, New Mexico, Oklahoma, Arkansas, Louisiana, Mississippi, Alabama,
Colorado, Utah, Wyoming, Montana, North Dakota, South Dakota, Pennsylvania and Western Canada,
while our pressure pumping services are focused primarily in the Appalachian Basin. Our drilling
and completion fluids services are provided to operators offshore in the Gulf of Mexico and on land
in Texas, Southeastern New Mexico, Oklahoma and the Gulf Coast region of Louisiana. The oil and
natural gas properties in which we hold working interests are primarily located in West and South
Texas, Southeastern New Mexico, Utah and Mississippi.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our consolidated net income for the second quarter of 2008 decreased by $58.1&nbsp;million or 42%
as compared to the second quarter of 2007. Included in consolidated net income for the second
quarter of 2007 was a pre-tax gain of approximately $41.9&nbsp;million associated with the recovery of
embezzled funds and approximately $16.5&nbsp;million in net pre-tax gains from the disposal of certain
oil and natural gas properties and other assets. Excluding the above-mentioned gains, our
consolidated net income for the second quarter of 2007 would have been approximately $102&nbsp;million
and the decrease in net income for the second quarter of 2008 would have been approximately $20.2
million or 20%.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Typically, the profitability of our business is most readily assessed by two primary
indicators in our contract drilling segment: our average number of rigs operating and our average
revenue per operating day. During the second quarter of 2008, our average number of rigs operating
was 244 per day compared to 237 in the second quarter of 2007. Our average revenue per operating
day was $18,740 in the second quarter of 2008 compared to $19,410 in the second quarter of 2007.
The decrease in our consolidated net income was primarily due to our contract drilling segment
experiencing a decrease in the average revenue per operating day and an increase in the average
costs per operating day in the second quarter of 2008 as compared to the second quarter of 2007.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our revenues, profitability and cash flows are highly dependent upon prevailing prices for
natural gas and, to a lesser extent, oil. During periods of improved commodity prices, the capital
spending budgets of oil and natural gas operators tend to expand, which results in increased demand
for our contract services. Conversely, in periods when these commodity prices deteriorate, the
demand for our contract services generally weakens and we experience downward pressure on pricing
for our services. In addition, our operations are highly impacted by competition, the availability
of excess equipment, labor issues and various other factors which are more fully described as &#147;Risk
Factors&#148; included as Item&nbsp;1A in our Annual Report on Form 10-K for the fiscal year ended December
31, 2007.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We believe that the liquidity shown on our balance sheet as of June&nbsp;30, 2008, which includes
approximately $335&nbsp;million in working capital (including $62.2&nbsp;million in cash and cash
equivalents) and approximately $316&nbsp;million available under a $375&nbsp;million line of credit, provides

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As of June&nbsp;30, 2008, we had non-cancelable commitments to purchase approximately $61.7&nbsp;million
of equipment. In addition to commitments at June&nbsp;30, 2008, we entered into agreements in July&nbsp;2008
to purchase new drilling equipment totaling approximately $111&nbsp;million.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>Trading and Investing </I>&#151; We have not engaged in trading activities that include high-risk
securities, such as derivatives and non-exchange traded contracts. We invest cash primarily in
highly liquid, short-term investments such as overnight deposits and money market accounts.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>Description of Business </I>&#151; We conduct our contract drilling operations in Texas, New Mexico,
Oklahoma, Arkansas, Louisiana, Mississippi, Alabama, Colorado, Utah, Wyoming, Montana, North
Dakota, South Dakota, Pennsylvania and Western Canada. As of June&nbsp;30, 2008, we had approximately
350 currently marketable land-based drilling rigs. We provide pressure pumping services to oil and
natural gas operators primarily in the Appalachian Basin. These services consist primarily of well
stimulation and cementing for completion of new wells and remedial work on existing wells. We
provide drilling fluids, completion fluids and related services to oil and natural gas operators
offshore in the Gulf of Mexico and on land in Texas, Southeastern New Mexico, Oklahoma and the Gulf
Coast region of Louisiana. Drilling and completion fluids are used by oil and natural gas
operators during the drilling process to control pressure when drilling oil and natural gas wells.
We also invest, on a working interest basis, in oil and natural gas properties.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The North American land drilling industry has experienced periods of downturn in demand at
various times during the last decade. During these periods, there have been substantially more
drilling rigs available than necessary to meet demand. As a result, drilling contractors have had
difficulty sustaining profit margins during the downturn periods.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In addition to adverse effects that future declines in demand could have on us, ongoing
factors which could continue to adversely affect utilization rates and pricing, even in an
environment of high oil and natural gas prices and increased drilling activity, include:

</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As a result of an increase in drilling activity and increased prices for drilling services in
2005 and 2006, construction of new drilling rigs increased significantly in that time period. The
addition of new drilling rigs to the market resulted in excess capacity compared to demand, and
construction of new drilling rigs moderated in 2007. With a recent increase in demand in 2008, we
believe that further construction of new drilling rigs will continue. We cannot predict either the
future level of demand for our contract drilling services or future conditions in the oil and
natural gas contract drilling business.

amount of $0.16 per share to be paid on September&nbsp;30, 2008 to holders of record as of September&nbsp;12,
2008. The amount and timing of all future dividend payments, if any, is subject to the discretion
of the Board of Directors and will depend upon business conditions, results of operations,
financial condition, terms of our credit facilities and other factors.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On August&nbsp;1, 2007, our Board of Directors approved a stock buyback program (&#147;Program&#148;),
authorizing purchases of up to $250&nbsp;million of our common stock in open market or privately
negotiated transactions. As of June&nbsp;30, 2008, we had authority remaining under the Program to
purchase approximately $180&nbsp;million of our outstanding common stock. Shares purchased under the

acquisition opportunities are evaluated. The timing, size or success of any acquisition and the
associated capital commitments are unpredictable. Should opportunities for growth requiring
capital arise, we believe we would be able to satisfy these needs through a combination of working
capital, cash generated from operations, our existing credit facility and additional debt or equity
financing. However, there can be no assurance that such capital would be available on reasonable
terms, if at all.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Revenues and direct operating costs increased as a result of an increase in the average
revenue and average direct operating costs per job. Increased average revenue per job was due to
increased pricing for our services and an increase in larger jobs being driven by demand for
services associated with unconventional reservoirs in the Appalachian Basin. Average direct
operating costs per job increased as a result of increases in compensation, maintenance and the
cost of materials used in our operations, as well as an increase in larger jobs. Selling, general
and administrative expense increased primarily as a result of expenses to support the expanding
operations of the pressure pumping segment. Significant capital expenditures have been incurred to
add capacity, expand our areas of operation and modify and upgrade existing equipment. The
increase in depreciation expense is a result of the capital expenditures discussed above.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Revenues increased due to an increase in the average sales price of oil and natural gas
partially offset by a decrease in the average net daily production of oil and natural gas and by
the elimination of well operations revenue due to the sale in the fourth quarter of 2007 of the
operating responsibilities associated with oil and natural gas wells. Average net daily oil and
natural gas production decreased primarily due to production declines. The increase in direct
operating costs is due to an increase of approximately $610,000 in costs associated with the
abandonment of exploratory wells, as well as increased production taxes and other production costs.
Selling, general and administrative expenses decreased in the second quarter of 2008 due to the
sale of operating responsibilities mentioned above and the resulting elimination of headcount in
our oil and natural gas production and exploration segment. Depreciation, depletion and impairment
expense in the second quarter of 2008 includes approximately $79,000 incurred to impair certain oil
and natural gas properties compared to approximately $534,000 incurred to impair certain oil and
natural gas properties in

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Selling, general and administrative expense increased primarily as a result of additional
compensation expense and an increase in payroll tax expense associated with the exercise of stock
options during the second quarter of 2008. The decrease in gain on disposal of assets in the
second quarter of 2008 compared to the second quarter of 2007 is due to a sale in the second
quarter of 2007 of certain oil and natural gas properties. Gains and losses on the disposal of
assets are considered as part of our corporate activities due to the fact that such transactions
relate to decisions of the executive management group regarding corporate strategy. Embezzlement
costs (recoveries)&nbsp;in the second quarter of 2007 includes a recovery of $42.5&nbsp;million, reduced by
approximately $600,000 in professional and other costs incurred.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Revenues in the first six months of 2008 decreased as compared to the first six months of 2007
as a result of decreases in the average revenue per operating day and in the number of operating
days. Direct operating costs in the first six months of 2008 increased as compared to the first
six months of 2007 as a result of the increase in average direct operating costs per operating day.
The increase in average direct operating costs per operating day includes costs incurred in
activating drilling rigs. The reactivation and construction of new land drilling rigs in the
United States has resulted in excess capacity compared to demand. Operating days, average rigs
operating and average revenue per operating day decreased in the first six months of 2008 as a
result of the excess capacity of drilling rigs. Significant capital expenditures have been
incurred to build new drilling rigs, to modify and upgrade our drilling rigs and to acquire
additional related equipment such as drill pipe, drill collars, engines, fluid circulating systems,
rig hoisting systems and safety enhancement equipment. The increase in depreciation expense was a
result of the capital expenditures discussed above.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Revenues and direct operating costs increased as a result of an increase in the average
revenue and average direct operating costs per job. Increased average revenue per job was due to
increased pricing for our services and an increase in larger jobs being driven by demand for
services associated with unconventional reservoirs in the Appalachian Basin. Average direct
operating costs per job increased as a result of increases in compensation, maintenance and the
cost of materials used in our operations, as well as an increase in larger jobs. Selling, general
and administrative expense increased primarily as a result of expenses to support the expanding
operations of the pressure pumping segment. Significant capital expenditures have been incurred to
add capacity, expand our areas of operation and modify and upgrade existing equipment. The
increase in depreciation expense is a result of the capital expenditures discussed above.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Revenues increased due to an increase in the average sales price of oil and natural gas
partially offset by a decrease in the average net daily production of oil and natural gas and by
the elimination of well operations revenue due to the sale in the fourth quarter of 2007 of the
operating responsibilities associated with oil and natural gas wells. Average net daily oil and
natural gas production decreased primarily due to the sale of properties in 2007 and production
declines. Selling, general and administrative expenses decreased in the first six months of 2008
due to the sale of the operating responsibilities mentioned above and the resulting elimination of
headcount in our oil and natural gas production and exploration segment. Depreciation, depletion
and impairment expense in the first six months of 2008 includes approximately $300,000 incurred to
impair certain oil and natural gas properties compared to approximately $1.1&nbsp;million incurred to
impair certain oil and natural gas properties in the first six months of 2007. Depletion expense
decreased approximately $1.2&nbsp;million primarily due to the sale of certain properties in 2007.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Selling, general and administrative expense increased primarily as a result of additional
compensation expense and an increase in payroll tax expense associated with the exercise of stock
options during the first six months of 2008. The decrease in gain on disposal of assets in the
first six months of 2008 compared to the first six months of 2007 is due to a sale in 2007 of
certain oil and natural gas properties. Gains and losses on the disposal of assets are considered
part of our corporate activities due to the fact that such transactions relate to decisions of the
executive management group regarding corporate strategy. Embezzlement costs (recoveries)&nbsp;in the
first six months of 2007 included a recovery of $42.5&nbsp;million, reduced by approximately $600,000 in
professional and other costs incurred.

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In September&nbsp;2006, the FASB issued Statement No.&nbsp;157, <I>Fair Value Measurements </I>(&#147;FAS 157&#148;).
FAS 157 defines fair value, establishes a framework for measuring fair value in generally accepted
accounting principles, and expands disclosures about fair value measurement. The initial
application of FAS 157 is limited to financial assets and liabilities and became effective on
January&nbsp;1, 2008 for us. The impact of the initial application was not material. We will adopt FAS
157 on a prospective basis for nonfinancial assets and liabilities that are not measured at fair
value on a recurring basis on January&nbsp;1, 2009. The application of FAS 157 to our nonfinancial
assets and liabilities will primarily be limited to assets acquired and liabilities assumed in a
business combination, asset retirement obligations and asset impairments, including goodwill and
long-lived assets. This application of FAS 157 is not expected to have a material impact to us.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In June&nbsp;2008, the FASB issued FASB Staff Position No.&nbsp;EITF 03-6-1, <I>Determining Whether
Instruments Granted in Share-Based Payment Transactions Are Participating Securities </I>(&#147;FSP EITF
03-6-1&#148;). FSB EITF 03-6-1 clarifies that share-based payment awards that entitle their holders to
receive nonforfeitable dividends before vesting should be considered participating securities and,
as such, should be included in the calculation of basic earnings-per-share using the two-class
method. Certain of our share-based payment awards entitle the holders to receive nonforfeitable
dividends and the application of the provisions of FSP EITF 03-6-1 may have the effect of reducing
basic and diluted earnings-per-share by an immaterial amount. FSP EITF 03-6-1 is effective for
financial statements issued for fiscal years beginning after December&nbsp;15, 2008, as well as interim
periods within those years. Once effective, all prior-period earnings-per-share data presented
must be adjusted retrospectively to conform with the provisions of the FSP. The FSP will be
effective for us beginning in the quarter ending March&nbsp;31, 2009 and early application is not
permitted.

<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>Volatility of Oil and Natural Gas Prices and its Impact on Operations</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our revenue, profitability, and rate of growth are substantially dependent upon prevailing
prices for natural gas and, to a lesser extent, oil. For many years, oil and natural gas prices
and markets have been volatile. Prices are affected by market supply and demand factors as well as
international military, political and economic conditions, and the ability of OPEC to set and
maintain production and price targets. All of these factors are beyond our control. During 2006,
the average market price of natural gas retreated from record highs that were set in 2005. The
price dropped from an average of $8.98 per Mcf in 2005 to an average of $6.94 per Mcf in 2006 and
an average of $7.18 per Mcf in 2007. This resulted in our customers moderating their increase in
drilling activities during 2007. This moderation combined with the reactivation and construction
of new land drilling rigs in the United States resulted in excess capacity. Prices have rebounded
to an average of $10.33 per Mcf for the first six months of 2008 and activity has increased. We
expect oil and natural gas prices to continue to be volatile and to affect our financial condition,
operations and ability to access sources of capital. A significant decrease in market prices for
natural gas could result in a material decrease in demand for drilling rigs and adversely affect
our operating results.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The North American land drilling industry has experienced many downturns in demand at various
times during the last decade. During these periods, there have been substantially more drilling
rigs available than necessary to meet demand. As a result, drilling contractors have had
difficulty sustaining profit margins during the downturn periods.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We currently have exposure to interest rate market risk associated with borrowings under our
credit facility. The revolving credit facility calls for periodic interest payments at a floating
rate ranging from LIBOR plus 0.625% to 1.0% or at the prime rate at our election. The applicable
rate above LIBOR is based upon our debt to capitalization ratio. Our exposure to interest rate
risk due to changes in the prime rate or LIBOR is not material due to the fact that we had no
outstanding borrowings as of June&nbsp;30, 2008.
