<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The unaudited interim 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. Except for wholly-owned subsidiaries, the Company
has no controlling financial interests in any entity which would require consolidation.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The unaudited interim consolidated financial statements have been prepared by management of
the Company 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, 2008, as presented herein, was derived from
the audited consolidated 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, 2008. The results of operations for the three and six months ended
June&nbsp;30, 2009 are not necessarily indicative of the results to be expected for the full year.
</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 uses the Canadian dollar as its 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 has performed an evaluation of subsequent events through
August&nbsp;4, 2009 at the time of issuance of the unaudited consolidated financial statements.

<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 (loss)&nbsp;per common share in its
Unaudited Consolidated Statements of Income: Basic net income (loss)&nbsp;per common share (&#147;Basic
EPS&#148;) and diluted net income (loss)&nbsp;per common share (&#147;Diluted EPS&#148;). The Company adopted the
provisions of 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;) in the quarter
ended March&nbsp;31, 2009. FSP EITF 03-6-1 clarifies that share-based payment awards that entitle their
holders to receive non-forfeitable dividends before vesting should be considered participating
securities and, as such, should be included in the calculation of earnings-per-share using the
two-class method. All earnings per share data presented for the three and six months ended June
30, 2008 has been adjusted retrospectively to conform with the provisions of FSP EITF 03-6-1. The
impact of this retrospective application was to reduce Basic EPS for the three months ended June
30, 2008 by $0.01 and to reduce Basic EPS and Diluted EPS for the six months ended June&nbsp;30, 2008 by
$0.01.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Basic EPS excludes dilution and is computed by first allocating earnings between common
stockholders and holders of non-vested shares of restricted stock. Basic EPS is then determined by
dividing the earnings attributable to common stockholders by the weighted average number of common
shares outstanding during the period, excluding non-vested shares of
restricted stock.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Diluted EPS is based on the weighted average number of common shares outstanding plus the
dilutive effect of potential common shares, including stock options, non-vested shares of
restricted stock and restricted stock units. The dilutive effect of stock options and restricted
stock units is determined based on the treasury stock method. The dilutive effect of non-vested
shares of restricted stock is based on the more dilutive of the treasury stock method or the
two-class method, assuming a reallocation of undistributed earnings to common stockholders after
considering the dilutive effect of potential common shares other than non-vested shares of
restricted stock.

<!-- xbrl,body -->
<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-based method. The
Company uses share-based awards to compensate employees and non-employee directors. All
share-based awards have been equity instruments in the form of stock options, restricted stock or
restricted stock units and have included service and, in certain cases, performance conditions.
The Company issues shares of common stock when vested stock options are exercised, when restricted
stock is granted and when restricted stock units 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, 2009 and 2008 follow:

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. The results of operations in these segments are regularly reviewed by the chief operating
decision maker for purposes of determining resource allocation and assessing performance. Separate
financial data for each of our four business segments is provided in the table below (in

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Interest is paid on the outstanding principal amount of LOC borrowings at a floating rate
based on, at the Company&#146;s election, LIBOR or a base rate. The margin on LIBOR loans ranges from
3.00% to 4.00% and the margin on base rate loans ranges from 2.00% to 3.00%, based on the Company&#146;s
debt to capitalization ratio. At June&nbsp;30, 2009, the margin on LIBOR loans would have been 3.00%
and the margin on base rate loans would have been 2.00%. Any outstanding borrowings must be repaid
at maturity on January&nbsp;31, 2012 and letters of credit may remain in effect up to six months after
such maturity date. This LOC facility includes various fees, including a commitment fee on the
actual daily unused commitment (the commitment fee rate was 1.00% at June&nbsp;30, 2009).

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;There are customary representations, warranties, 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, 2009, the
Company had no borrowings outstanding under the LOC. The Company had $46.3&nbsp;million in letters of
credit outstanding at June&nbsp;30, 2009 and, as a result, had available borrowing capacity of
approximately $194&nbsp;million at that date. Each domestic subsidiary of the Company has
unconditionally guaranteed the existing and future obligations of the Company and each other
guarantor under the LOC and related loan documents, as well as obligations of the Company and its
subsidiaries under any interest rate swap contracts that may be entered into with lenders party to the LOC.

<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. During the six months ended June&nbsp;30, 2009, the
Company purchased 3,324 shares of its common stock under the Program at a cost of approximately
$46,000. As of June&nbsp;30, 2009, the Company is authorized to purchase approximately $113&nbsp;million of
the Company&#146;s outstanding common stock under the Program. 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 85,817 shares of stock from employees during the six months ended June
30, 2009 on dates that corresponded with the vesting of restricted stock. These shares were
purchased at fair market value to provide employees with the funds necessary to satisfy payroll tax
withholding obligations and have been accounted for as treasury stock. The total purchase price
for these shares was approximately $1.1&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 align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
September 2006, the FASB issued Statement No. 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 was limited to financial assets and liabilities and
became effective on January 1, 2008 for the Company.  The impact of the initial application
of FAS 157 was not material.  On January 1, 2009, the Company adopted FAS 157 on a prospective
basis for non-financial assets and liabilities that are not measured at fair value on a
recurring basis.  The application of FAS 157 to the Company&#146;s non-financial assets and
liabilities is primarily 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 has not had a material impact on the Company.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In December&nbsp;2007, the FASB issued Statement No.&nbsp;141(R), <I>Business Combinations </I>(&#147;FAS 141(R)&#148;)
and Statement No.&nbsp;160, <I>Noncontrolling Interests in Consolidated Financial Statements, an amendment
of ARB No.&nbsp;51 </I>(&#147;FAS 160&#148;). FAS 141(R) is a revision of Statement No.&nbsp;141, <I>Business Combinations</I>,
and calls for significant changes from current practice in accounting for business combinations.
FAS 141(R) is effective for business combinations for which the acquisition date is on or after the
beginning of the first annual reporting period beginning on or after December&nbsp;15, 2008. FAS 160
amends ARB 51 to establish accounting and reporting standards for the non-controlling interest in a
subsidiary and for the deconsolidation of a subsidiary. FAS 160 is effective for fiscal years
beginning on or after December&nbsp;15, 2008. Both FAS 141(R) and FAS 160 became effective for the
Company on January&nbsp;1, 2009. The application of FAS 141(R) and FAS 160 did not have a material
impact on 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;). FSP EITF 03-6-1 clarifies that share-based payment awards that entitle their holders to
receive non-forfeitable 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
non-forfeitable dividends. 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 and became
effective for the Company on January&nbsp;1, 2009. The impact of the adoption of FSP EITF 03-6-1 is
discussed in Note 1.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In December&nbsp;2008, the SEC issued a Final Rule, <I>Modernization of Oil and Gas Reporting </I>(&#147;Final
Rule&#148;). The Final Rule revises certain oil and gas reporting disclosures in Regulation&nbsp;S-K and
Regulation&nbsp;S-X under the Securities Act of 1933, as amended (the &#147;Securities Act&#148;) and the
Securities Exchange Act of 1934, as amended (the &#147;Exchange Act&#148;), as well as Industry Guide 2. The
amendments are designed to modernize and update oil and gas disclosure requirements to align them
with current practices and changes in technology. The disclosure requirements are effective for
registration statements filed on or after January&nbsp;1, 2010 and for annual financial statements filed
on or after December&nbsp;31, 2009. The Company is currently evaluating the impact that the Final Rule
may have on its consolidated financial statements.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In April&nbsp;2009, the FASB issued FASB Staff Position
No.&nbsp;157-4, <I>Determining Fair Value When the Volume and Level
of Activity for the Asset or Liability Have Significantly Decreased
and Identifying Transactions That Are Not Orderly </I>(&#147;FSP 157-4&#148;). FSP 157-4 provides additional
guidance for determining whether a market for a financial asset is not active and a transaction is
not distressed for fair value measurements under FAS 157. The provisions of this FSP are effective
for financial statements issued for interim and annual periods ending after June&nbsp;15, 2009 and
became effective for the Company in the quarter ended June&nbsp;30, 2009. The adoption of FSP 157-4 did
not have a material impact on the Company.

<Div align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In April&nbsp;2009, the FASB issued FASB Staff Position No.&nbsp;107-1 and APB No.&nbsp;28-1, <I>Interim
Disclosures about Fair Value of Financial Instruments </I>(&#147;FSP 107-1&#148;). This FSP increases the
frequency of fair value disclosures as required by FAS 107, <I>Disclosures about Fair Value of
Financial Instruments</I>, from annual only to quarterly reporting periods. The provisions of this FSP
are effective for financial statements issued for interim and annual periods ending after June&nbsp;15,

107-1 did not have a material impact on the Company.

46(R) with the addition of entities previously considered qualifying special-purpose entities and
requires ongoing reassessments of whether an enterprise is the primary beneficiary of a variable
interest entity. Before this Statement, FASB Interpretation No.&nbsp;46(R) required reconsideration of
whether an enterprise is the primary beneficiary of a variable interest entity only when specific
events occurred. FAS 167 is effective as of the beginning of each

<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, Arizona, Utah, Wyoming, Montana, North Dakota, South Dakota, Pennsylvania, West Virginia
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, New Mexico, Oklahoma and Louisiana. The oil and natural gas
properties in which we hold interests are primarily located in Texas, New Mexico, Mississippi and
Louisiana.
</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 2009, our average number of rigs operating
was 63 compared to 244 in the second quarter of 2008. Our average number of rigs operating during
the second quarter of 2009 included approximately seven rigs under term contracts that earned
standby revenues of $7.5&nbsp;million. Rigs on standby earn a discounted dayrate since they do not have
crews and have lower costs. Additionally, we recognized $901,000 of revenues during the second
quarter of 2009 from the early termination of term contracts. Our average revenue per operating
day was $17,780 in the second quarter of 2009 compared to $18,740 in the second quarter of 2008.
We had a consolidated net loss of $17.7&nbsp;million for the second quarter of 2009 compared to
consolidated net income of $81.4&nbsp;million for the second quarter of 2008. This decrease was
primarily due to our contract drilling segment experiencing a significant decrease in the average
number of rigs operating as compared to the second quarter of 2008.
</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 generally 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. Since reaching a peak in 2008, there has been a significant
decline in oil and natural gas prices. During this time there has also been a substantial
deterioration in the global economic environment. As part of this deterioration, there has been
substantial uncertainty in the capital markets and access to financing has been reduced. Due to
these conditions, our customers have reduced or curtailed their drilling programs, which has
resulted in a decrease in demand for our services, as evidenced by the decline in our monthly
average of rigs operating from a high of 283 in October&nbsp;2008 to 60 in June&nbsp;2009. Furthermore, these
factors could result in certain of our customers experiencing an inability to pay suppliers,
including us, if they are not able to access capital to fund their operations. We are also highly
impacted by competition, the availability of excess equipment, labor issues and various other
factors that could materially adversely affect our business, financial condition, cash flows and
results of operations. Please see &#147;Risk Factors&#148; included as Item&nbsp;1A in our Annual Report on Form
10-K for the fiscal year ended December&nbsp;31, 2008.
</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, 2009, which includes
approximately $230&nbsp;million in working capital (including $168&nbsp;million in cash and cash equivalents)
and approximately $194&nbsp;million available under our current $240&nbsp;million line of credit, together
with cash expected to be generated from operations, should provide us with sufficient ability to
fund our current plans to build new equipment, make improvements to our existing equipment, expand
into new regions, pay cash dividends and survive the current downturn in our industry.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>Commitments and Contingencies </I>&#151; As of June&nbsp;30, 2009, we maintained letters of credit in the
aggregate amount of $46.3&nbsp;million for the benefit of various insurance companies as collateral for
retrospective premiums and retained losses which could become payable under the terms of the
underlying insurance contracts. These letters of credit expire at various times during each
calendar year and are typically renewed annually. As of June&nbsp;30, 2009, no amounts had been drawn
under the letters of credit.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As of June&nbsp;30, 2009, we had commitments to purchase approximately $154&nbsp;million of major

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, Arizona, Utah, Wyoming, Montana,
North Dakota, South Dakota, Pennsylvania, West Virginia and western Canada. As of June&nbsp;30, 2009,
we had approximately 350 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, New Mexico, Oklahoma and
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 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 and, at times, have incurred losses 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 declines in demand have had or 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 align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On July&nbsp;29, 2009, our Board of Directors approved a cash dividend on our common stock in the
amount of $0.05 per share to be paid on September&nbsp;30, 2009 to holders of record as of September&nbsp;15,
2009. 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. During the six months ended June&nbsp;30, 2009, we purchased 3,324 shares of
our common stock under the Program at a cost of approximately $46,000. As of June&nbsp;30, 2009, we are
authorized to purchase approximately $113&nbsp;million of our outstanding common stock under the
Program. Shares purchased under the Program have been accounted for as treasury stock.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We have an unsecured revolving line of credit with a maximum borrowing and letter of credit
capacity of $240&nbsp;million. Interest is paid on the outstanding principal amount of borrowings under
the revolving line of credit at a floating rate based on, at our election, LIBOR or a base rate.
The margin on LIBOR loans ranges from 3.00% to 4.00% and the margin on base rate loans ranges from
2.00% to 3.00%, based on our debt to capitalization ratio. Any outstanding borrowings must be
repaid at maturity on January&nbsp;31, 2012 and letters of credit may remain in effect up to six months
after such maturity date. As of June&nbsp;30, 2009, we had no borrowings outstanding under this
revolving line of credit. We had $46.3&nbsp;million in letters of credit outstanding at June&nbsp;30, 2009
and, as a result, had available borrowing capacity of approximately $194&nbsp;million at such date.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We believe that the current level of cash, short-term investments and borrowing capacity
available under our current revolving line of credit, together with cash expected to be generated
from operations, should be sufficient to meet our current capital needs. From time to time,
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, borrowing capacity under our existing LOC or additional
debt or equity financing. However, there can be no assurance that such capital will be available
on reasonable terms, if at all.

second quarter of 2008 primarily as a result of a decrease in the number of operating days. The
decrease in operating days was due to decreased demand largely caused by lower commodity prices for
natural gas and oil. Our average number of rigs operating during the second quarter of 2009
included an average of approximately seven rigs that earned standby
revenues of $7.5&nbsp;million. Rigs on standby earn a discounted
dayrate as they do not have crews
and have lower costs. Additionally, we recognized $901,000 of revenues during the second quarter
of 2009 from the early termination of drilling contracts. Excluding the impact of standby revenues

second quarter of 2009 compared to the second quarter of 2008 primarily due to decreases in
dayrates for rigs that were operating  in the spot market and the
expiration of term contracts that were at higher rates. Average direct operating costs per

primarily due to decreases in labor and repair costs as well as the impact of rigs earning standby
revenues for which no crews were maintained in the second quarter of 2009. 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.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our customers have increased their focus on the emerging development of unconventional
reservoirs in the Appalachian Basin and the larger jobs associated therewith. As a result of this
focus on unconventional reservoirs and declining commodity prices, we have experienced a decrease
in the number of smaller traditional pressure pumping jobs, which has contributed to the overall
decrease in the number of total jobs. Revenues and direct operating costs decreased as a result of
a decrease in the number of total jobs. Increased average revenue per job was due to an increase
in the proportion of larger jobs to total jobs, which was driven by demand for services associated
with unconventional reservoirs partially offset by the impact of
reduced  pricing.
Average direct operating costs per job increased due to the increase
in larger jobs and as a result of fixed costs being spread over a
significantly reduced number of jobs. In anticipation of increased activity associated with the
unconventional reservoirs in the Appalachian Basin, we have added facilities, equipment and
personnel in recent years. Delays in the development of these reservoirs and lower commodity
prices have caused less demand for our pressure pumping services, negatively
impacting the profitability of this business. Selling, general and administrative expenses
decreased in the second quarter of 2009 compared to the second quarter of 2008 primarily due to
 headcount reductions. Significant capital expenditures
have been incurred to add capacity and modify and upgrade existing equipment. The increase in
depreciation expense is a result of these capital expenditures.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Revenues decreased due to lower average sales prices and net daily production of oil and
natural gas. Average net daily oil and natural gas production decreased primarily due to
production declines on existing wells. Depreciation, depletion and impairment expense in the
second quarter of 2009 includes approximately $600,000 incurred to impair certain oil and natural
gas properties compared to approximately $79,000 incurred to impair certain oil and natural gas
properties in the second quarter of 2008. The increase in impairment charges in 2009 was due to a
reduction in commodity price expectations and a decline in production of certain wells. Depletion
expense decreased approximately $609,000 primarily due to the impact of decreases in carrying value
of properties resulting from impairment charges recognized prior to the second quarter of 2009.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Selling, general and administrative expenses increased in the second quarter of 2009 compared
to the second quarter of 2008 primarily as a result of increased
professional fees and increased non-cash stock based compensation. Other
operating expenses increased due to an increase in bad debt expense of $1.7&nbsp;million in the second
quarter of 2009 compared to the second quarter of 2008. Gains and losses on the disposal and
retirement of assets are treated as part of our corporate
activities because such
transactions relate to corporate strategy decisions of the
Company&#146;s executive management group.
In the second quarter of 2008 we recognized a net gain on the disposal of assets of approximately
$2.7&nbsp;million primarily due to the sale of certain assets in our
contract drilling segment.
Interest expense increased in the second quarter of 2009 compared to
the second quarter of 2008 due to amortization of LOC issuance costs
and increased fees associated with the unused portion of the LOC.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Revenues and direct operating costs decreased in the first six months of 2009 compared to the
first six months of 2008 primarily as a result of a decrease in the number of operating days. The
decrease in operating days was due to decreased demand largely caused by lower commodity prices for
natural gas and oil. Our average number of rigs operating during the first six months of 2009
included an average of approximately nine rigs  that earned standby
revenues of $18.1&nbsp;million. Rigs on standby earn a discounted
dayrate  as they do not have crews
and have lower costs. Additionally, we recognized $7.5&nbsp;million of revenues during the first six
months of 2009 from the early termination of drilling contracts.  Average direct operating
costs per operating day decreased in the first six months of 2009 compared to the first six months
of 2008 primarily due to decreases in labor and repair costs as well as the impact of rigs earning
standby revenues for which no crews were maintained in the first six months of 2009. Selling,
general and administrative expenses decreased in the first six months of 2009 compared to the first
six months of 2008 primarily as a result of lower professional fees
and headcount reductions. 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.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our customers have increased their focus on the emerging development of unconventional
reservoirs in the Appalachian Basin and the larger jobs associated therewith. As a result of this
focus on unconventional reservoirs and declining commodity prices, we have experienced a decrease
in the number of smaller traditional pressure pumping jobs, which has contributed to the overall
decrease in the number of total jobs. Revenues and direct operating costs decreased as a result of
a decrease in the number of total jobs. Increased average revenue per job was due to an increase
in the proportion of larger jobs to total jobs, which was driven by demand for services associated
with unconventional reservoirs partially offset by the impact of
reduced pricing.
Average direct operating costs per job increased due to the increase
in larger jobs and as a result of fixed costs being spread over a
significantly reduced number of jobs. In anticipation of increased activity associated with the
unconventional reservoirs in the Appalachian Basin, we have added facilities, equipment and
personnel in recent years. Delays in the development of these reservoirs and lower
commodity prices have caused less demand for our pressure pumping services,
negatively impacting the profitability of this business. 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 these capital expenditures.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Revenues decreased primarily due to lower average sales prices of oil and natural gas.
Average net daily oil production increased due to the addition of new wells. Average net daily
natural gas production decreased primarily due to production declines on existing wells.
Depreciation, depletion and impairment expense in the first six months of 2009 includes
approximately $3.1&nbsp;million incurred to impair certain oil and natural gas properties compared to
approximately $300,000 incurred to impair certain oil and natural gas properties in the first six
months of 2008. The increase in impairment charges in 2009 was due to a reduction in commodity
price expectations and a decline in production of certain wells. Depletion expense increased
approximately $518,000 due to lower reserves, which resulted from decreased oil and natural gas
commodity prices.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Other operating expenses increased due to an increase in bad debt expense of $5.4&nbsp;million in
the first six months of 2009 compared to the first six months of 2008. Gains and losses on the
disposal and retirement of assets are treated as part of our
corporate activities because such transactions relate to corporate strategy decisions of
the Company&#146;s executive management group. In the first six months of 2008 we recognized a net gain on the disposal of
assets of approximately $2.5&nbsp;million primarily due to the sale of certain assets in our contract
drilling segment. Interest expense increased in the first six months of
2009 compared to the first six months of 2008 due to amortization of
LOC issuance costs and increased fees associated with the unused
portion of the LOC.

<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>Recently Issued Accounting Standards</B>
</DIV>
<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In September 2006, the
FASB issued Statement No. 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 was limited to financial assets and liabilities and
 became effective on January 1, 2008 for us.
 The impact of the initial application of FAS 157 was not material.  On January 1, 2009, we adopted FAS 157 on
 a prospective basis for non-financial assets and liabilities that are not measured at fair value on a recurring basis.  The application of FAS 157 to our non-financial assets and liabilities is primarily 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 has not had a material impact on us.</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In December&nbsp;2007, the FASB issued Statement No.&nbsp;141(R), <I>Business Combinations </I>(&#147;FAS 141(R)&#148;)
and Statement No.&nbsp;160, <I>Noncontrolling Interests in Consolidated Financial Statements, an amendment
of ARB No.&nbsp;51 </I>(&#147;FAS 160&#148;). FAS 141(R) is a revision of Statement No.&nbsp;141, <I>Business Combinations</I>,
and calls for significant changes from current practice in accounting for business combinations.
FAS 141(R) is effective for business combinations for which the acquisition date is on or after the
beginning of the first annual reporting period beginning on or after December&nbsp;15, 2008. FAS 160
amends ARB 51 to establish accounting and reporting standards for the non-controlling interest in a
subsidiary and for the deconsolidation of a subsidiary. FAS 160 is effective for fiscal years
beginning on or after December&nbsp;15, 2008. Both FAS 141(R) and FAS 160 became effective for us on
January&nbsp;1, 2009. The application of FAS 141(R) and FAS 160 did
not have a material impact on 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;). FSP EITF 03-6-1 clarifies that share-based payment awards that entitle their holders to
receive non-forfeitable 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 non-forfeitable
dividends. 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 and became effective for us
on January&nbsp;1, 2009. The adoption of FSP EITF 03-6-1 has not had
a material impact on us.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In December&nbsp;2008, the SEC issued a final rule, <I>Modernization of Oil and Gas Reporting </I>(&#147;Final
Rule&#148;). The Final Rule revises certain oil and gas reporting disclosures in Regulation&nbsp;S-K and
Regulation&nbsp;S-X under the Securities Act and the Exchange Act, as well as Industry Guide 2. The
amendments are designed to modernize and update oil and gas disclosure requirements to align them
with current practices and changes in technology. The disclosure requirements are effective for
registration statements filed on or after January&nbsp;1, 2010 and for annual financial statements filed
on or after December&nbsp;31, 2009. We are currently evaluating the impact that the Final Rule may have
on our consolidated financial statements.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In

<I>Determining Fair Value When the Volume and Level of Activity for
the Asset or Liability Have significantly Decreased and Identifying
Transactions That Are Not Orderly.</I> (&#147;FSP 157-4&#148;). FSP 157-4 provides additional
guidance for determining whether a market for a financial asset is not active and a transaction is
not distressed for fair value measurements under FAS 157. The provisions of this FSP are effective
for financial statements issued for interim and annual periods ending after June&nbsp;15, 2009 and
became effective for us in the quarter ended June&nbsp;30, 2009. The adoption of FSP 157-4 did not have
a material impact on us.

frequency of fair value disclosures as required by FAS 107, <I>Disclosures about Fair Value of

are effective for financial statements issued for interim and annual periods ending after June&nbsp;15,

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


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our revenue, profitability, financial condition 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 extremely 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 2008, the monthly average market price of natural gas peaked in June at $13.06
per Mcf before rapidly declining to an average of $5.99 per Mcf in December. In 2009, the
average market price of natural gas declined further to an average
of $3.91 per Mcf in  the month of June. This has resulted in our
customers significantly reducing their drilling activities beginning in the fourth quarter of 2008
and continuing into 2009. This reduction in demand combined with the reactivation and construction
of new land drilling rigs in the United States during the last several years has resulted in excess
capacity compared to demand. As a result of these factors, our average number of rigs operating
has declined significantly. 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. Continued low
market prices for natural gas will likely result in demand for our drilling rigs remaining low and
adversely affect our operating results, financial condition and cash flows.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The North American land drilling industry has experienced downturns in demand 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 and, at times, have incurred losses during the downturn periods.

</DIV>


<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 any borrowings that we
have under our LOC. The LOC calls for periodic interest payments at a floating rate ranging from
LIBOR plus 3.00% to 4.00% or at a base rate plus 2.00% to 3.00%. The applicable rate above LIBOR
or the prime rate is based upon our debt to capitalization ratio. As of June&nbsp;30, 2009, we had no
borrowings outstanding under our LOC.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We conduct a portion of our business in Canadian dollars through our Canadian land-based
drilling operations. The exchange rate between Canadian dollars and U.S. dollars has fluctuated
during the last several years. If the value of the Canadian dollar against the U.S. dollar
weakens, revenues and earnings of our Canadian operations will be reduced and the value of our
Canadian net assets will decline when they are translated to U.S. dollars. This currency rate risk
is not material to our results of operations or financial condition.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Forward-looking statements may be made by management orally or in writing, including, but not
limited to our filings with the SEC under the Exchange Act and the Securities Act. &#147;Management&#146;s
Discussion and Analysis of Financial Condition and Results of Operations&#148; included in Item&nbsp;2 of
Part&nbsp;I of this Quarterly Report on Form 10-Q contains forward-looking statements which are made
pursuant to the &#147;safe harbor&#148; provisions of the Private Securities Litigation Reform Act of 1995.
These statements include, without limitation, statements relating to: liquidity; financing of
operations; continued volatility of oil and natural gas prices; source and sufficiency of funds
required for immediate capital needs and additional rig acquisitions (if further opportunities
arise); demand for our services; and other matters. Our forward-looking statements can be
identified by the fact that they do not relate strictly to historic or current facts and often use
words such as &#147;believes,&#148; &#147;budgeted,&#148; &#147;expects,&#148; &#147;estimates,&#148; &#147;project,&#148; &#147;will,&#148; &#147;could,&#148; &#147;may,&#148;

meaning. The forward-looking statements are based on certain assumptions and analyses we make in
light of our experience and our perception of historical trends, current conditions, expected
future developments and other factors we believe are appropriate in the circumstances. Although we
believe that the expectations reflected in such forward-looking statements are reasonable, we can
give no assurance that such expectations will prove to have been correct.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Forward-looking statements are not guarantees of future performance and a variety of factors
could cause actual results to differ materially from the anticipated or expected results expressed
in or suggested by these forward-looking statements. Factors that might cause or contribute to
such differences include, but are not limited to, deterioration of global economic conditions,
declines in oil and natural gas prices that could adversely affect demand for our services and
their associated effect on day rates, rig utilization and planned capital expenditures, excess
availability of land drilling rigs, including as a result of the reactivation or construction of
new land drilling rigs, adverse industry conditions, adverse credit and equity market conditions,
difficulty in integrating acquisitions, demand for oil and natural gas, shortages of rig equipment
and ability to retain management and field personnel. Refer to &#147;Risk Factors&#148; contained in Part&nbsp;1
of our Annual Report on Form 10-K for the year ended December&nbsp;31, 2008 for a more complete
discussion of these and other factors that might affect our performance and financial results.
These forward-looking statements are intended to relay our expectations about the future, and speak

forward-looking statement, whether as a result of new information, future events or otherwise.

   &lt;div align="left" style="font-size: 10pt; margin-top: 12pt"&gt;&lt;b&gt;1. Basis of Consolidation and Presentation&lt;/b&gt;
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The unaudited interim consolidated financial statements include the accounts of Patterson-UTI
   Energy, Inc. (the &amp;#8220;Company&amp;#8221;) and its wholly-owned subsidiaries. All significant intercompany
   accounts and transactions have been eliminated. Except for wholly-owned subsidiaries, the Company
   has no controlling financial interests in any entity which would require consolidation.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The unaudited interim consolidated financial statements have been prepared by management of
   the Company 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&amp;#160;31, 2008, as presented herein, was derived from
   the audited consolidated 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&amp;#8217;s Annual Report on Form 10-K for the
   fiscal year ended December&amp;#160;31, 2008. The results of operations for the three and six months ended
   June&amp;#160;30, 2009 are not necessarily indicative of the results to be expected for the full year.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The U.S. dollar is the functional currency for all of the Company&amp;#8217;s operations except for its
   Canadian operations, which uses the Canadian dollar as its functional currency. The effects of
   exchange rate changes are reflected in accumulated other comprehensive income, which is a separate
   component of stockholders&amp;#8217; equity.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The
   Company has performed an evaluation of subsequent events through
   August&amp;#160;4, 2009 at the time of issuance of the unaudited consolidated financial statements.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The Company provides a dual presentation of its net income (loss)&amp;#160;per common share in its
   Unaudited Consolidated Statements of Income: Basic net income (loss)&amp;#160;per common share (&amp;#8220;Basic
   EPS&amp;#8221;) and diluted net income (loss)&amp;#160;per common share (&amp;#8220;Diluted EPS&amp;#8221;). The Company adopted the
   provisions of FASB Staff Position No.&amp;#160;EITF 03-6-1, &lt;i&gt;Determining Whether Instruments Granted in
   Share-Based Payment Transactions Are Participating Securities &lt;/i&gt;(&amp;#8220;FSP EITF 03-6-1&amp;#8221;) in the quarter
   ended March&amp;#160;31, 2009. FSP EITF 03-6-1 clarifies that share-based payment awards that entitle their
   holders to receive non-forfeitable dividends before vesting should be considered participating
   securities and, as such, should be included in the calculation of earnings-per-share using the
   two-class method. All earnings per share data presented for the three and six months ended June
   30, 2008 has been adjusted retrospectively to conform with the provisions of FSP EITF 03-6-1. The
   impact of this retrospective application was to reduce Basic EPS for the three months ended June
   30, 2008 by $0.01 and to reduce Basic EPS and Diluted EPS for the six months ended June&amp;#160;30, 2008 by
   $0.01.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;Basic EPS excludes dilution and is computed by first allocating earnings between common
   stockholders and holders of non-vested shares of restricted stock. Basic EPS is then determined by
   dividing the earnings attributable to common stockholders by the weighted average number of common
   shares outstanding during the period, excluding non-vested shares of
   restricted stock.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;Diluted EPS is based on the weighted average number of common shares outstanding plus the
   dilutive effect of potential common shares, including stock options, non-vested shares of
   restricted stock and restricted stock units. The dilutive effect of stock options and restricted
   stock units is determined based on the treasury stock method. The dilutive effect of non-vested
   shares of restricted stock is based on the more dilutive of the treasury stock method or the
   two-class method, assuming a reallocation of undistributed earnings to common stockholders after
   considering the dilutive effect of potential common shares other than non-vested shares of
   restricted stock.

   &lt;div align="left" style="font-size: 10pt; margin-top: 12pt"&gt;&lt;b&gt;2. Stock-based Compensation&lt;/b&gt;

   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The Company recognizes the cost of share-based awards under the fair-value-based method. The
   Company uses share-based awards to compensate employees and non-employee directors. All
   share-based awards have been equity instruments in the form of stock options, restricted stock or
   restricted stock units and have included service and, in certain cases, performance conditions.
   The Company issues shares of common stock when vested stock options are exercised, when restricted
   stock is granted and when restricted stock units vest.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&lt;i&gt;Stock Options. &lt;/i&gt;The Company estimates the grant date fair values of stock options using the
   Black-Scholes-Merton valuation model (&amp;#8220;Black-Scholes&amp;#8221;). Volatility assumptions are based on the
   historic volatility of the Company&amp;#8217;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&amp;#8217;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&amp;#160;30, 2009 and 2008 follow:

       when the awards were made. Non-vested shares are subject to forfeiture for failure to fulfill
       service conditions and, in certain cases, performance conditions. Non-forfeitable dividends are
       paid on non-vested shares of restricted stock. For restricted stock awards made prior to 2008, the
       Company used the &amp;#8220;graded-vesting&amp;#8221; attribution method to recognize periodic compensation cost over
       the vesting period. For restricted stock awards made in 2008 and thereafter, the Company uses the
       straight-line method to recognize periodic compensation cost over the vesting period.

   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The Company&amp;#8217;s revenues, operating profits and identifiable assets are primarily attributable
   to four business segments: (i)&amp;#160;contract drilling of oil and natural gas wells, (ii)&amp;#160;pressure
   pumping services, (iii)&amp;#160;drilling and completion fluid services and (iv)&amp;#160;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&amp;#8217;s chief operating decision
   maker. The results of operations in these segments are regularly reviewed by the chief operating
   decision maker for purposes of determining resource allocation and assessing performance. Separate
   financial data for each of our four business segments is provided in the table below (in
   thousands):

   has decreased below its carrying value. For purposes of impairment testing, goodwill is evaluated
   at the reporting unit level. The Company&amp;#8217;s reporting units for impairment testing have been
   determined to be its operating segments.

   goodwill of $86.2&amp;#160;million, all in its
   contract drilling reporting unit. In the event that market conditions remain weak, the Company may
   be required to record an impairment of goodwill in its contract drilling reporting unit in the
   future, and such impairment could be material.

       amount not to exceed $450&amp;#160;million. On June&amp;#160;19, 2009, the Company entered into a Commitment
       Increase and Joinder Agreement to increase the maximum borrowing capacity to $240&amp;#160;million.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;Interest is paid on the outstanding principal amount of LOC borrowings at a floating rate
       based on, at the Company&amp;#8217;s election, LIBOR or a base rate. The margin on LIBOR loans ranges from
       3.00% to 4.00% and the margin on base rate loans ranges from 2.00% to 3.00%, based on the Company&amp;#8217;s
       debt to capitalization ratio. At June&amp;#160;30, 2009, the margin on LIBOR loans would have been 3.00%
   and the margin on base rate loans would have been 2.00%. Any outstanding borrowings must be repaid
       at maturity on January&amp;#160;31, 2012 and letters of credit may remain in effect up to six months after
       such maturity date. This LOC facility includes various fees, including a commitment fee on the
       actual daily unused commitment (the commitment fee rate was 1.00% at June&amp;#160;30, 2009).
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The Company incurred line of credit issuance costs of approximately $6.2&amp;#160;million during the
       six months ended June&amp;#160;30, 2009 in connection with the LOC. These costs are being amortized over
       the contractual term of the LOC as an adjustment to interest expense.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;There are customary representations, warranties, 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&amp;#160;30, 2009, the
       Company had no borrowings outstanding under the LOC. The Company had $46.3&amp;#160;million in letters of
       credit outstanding at June&amp;#160;30, 2009 and, as a result, had available borrowing capacity of
       approximately $194&amp;#160;million at that date. Each domestic subsidiary of the Company has
       unconditionally guaranteed the existing and future obligations of the Company and each other
       guarantor under the LOC and related loan documents, as well as obligations of the Company and its
       subsidiaries under any interest rate swap contracts that may be entered into with lenders party to the LOC.
   &lt;/div&gt;
   &lt;/div&gt;
   &lt;/body&gt;

       the Company&amp;#8217;s outstanding common stock under the Program. Shares purchased under the Program are
       accounted for as treasury stock.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The Company purchased 85,817 shares of stock from employees during the six months ended June
       30, 2009 on dates that corresponded with the vesting of restricted stock. These shares were
       purchased at fair market value to provide employees with the funds necessary to satisfy payroll tax
       withholding obligations and have been accounted for as treasury stock. The total purchase price
       for these shares was approximately $1.1&amp;#160;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.

   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;In
   September 2006, the FASB issued Statement No. 157, &lt;i&gt;Fair Value
   Measurements&lt;/i&gt; (&amp;#8220;FAS 157&amp;#8221;).
   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 was limited to financial assets and liabilities and
   became effective on January 1, 2008 for the Company.  The impact of the initial application
   of FAS 157 was not material.  On January 1, 2009, the Company adopted FAS 157 on a prospective
   basis for non-financial assets and liabilities that are not measured at fair value on a
   recurring basis.  The application of FAS 157 to the Company&amp;#8217;s non-financial assets and
   liabilities is primarily 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 has not had a material impact on the Company.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;In December&amp;#160;2007, the FASB issued Statement No.&amp;#160;141(R), &lt;i&gt;Business Combinations &lt;/i&gt;(&amp;#8220;FAS 141(R)&amp;#8221;)
   and Statement No.&amp;#160;160, &lt;i&gt;Noncontrolling Interests in Consolidated Financial Statements, an amendment
   of ARB No.&amp;#160;51 &lt;/i&gt;(&amp;#8220;FAS 160&amp;#8221;). FAS 141(R) is a revision of Statement No.&amp;#160;141, &lt;i&gt;Business Combinations&lt;/i&gt;,
   and calls for significant changes from current practice in accounting for business combinations.
   FAS 141(R) is effective for business combinations for which the acquisition date is on or after the
   beginning of the first annual reporting period beginning on or after December&amp;#160;15, 2008. FAS 160
   amends ARB 51 to establish accounting and reporting standards for the non-controlling interest in a
   subsidiary and for the deconsolidation of a subsidiary. FAS 160 is effective for fiscal years
   beginning on or after December&amp;#160;15, 2008. Both FAS 141(R) and FAS 160 became effective for the
   Company on January&amp;#160;1, 2009. The application of FAS 141(R) and FAS 160 did not have a material
   impact on the Company.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;In June&amp;#160;2008, the FASB issued FASB Staff Position No.&amp;#160;EITF 03-6-1, &lt;i&gt;Determining Whether
   Instruments Granted in Share-Based Payment Transactions Are Participating Securities &lt;/i&gt;(&amp;#8220;FSP EITF
   03-6-1&amp;#8221;). FSP EITF 03-6-1 clarifies that share-based payment awards that entitle their holders to
   receive non-forfeitable 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&amp;#8217;s share-based payment awards entitle the holders to receive
   non-forfeitable dividends. FSP EITF 03-6-1 is effective for financial statements issued for fiscal
   years beginning after December&amp;#160;15, 2008, as well as interim periods within those years and became
   effective for the Company on January&amp;#160;1, 2009. The impact of the adoption of FSP EITF 03-6-1 is
   discussed in Note 1.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;In December&amp;#160;2008, the SEC issued a Final Rule, &lt;i&gt;Modernization of Oil and Gas Reporting &lt;/i&gt;(&amp;#8220;Final
   Rule&amp;#8221;). The Final Rule revises certain oil and gas reporting disclosures in Regulation&amp;#160;S-K and
   Regulation&amp;#160;S-X under the Securities Act of 1933, as amended (the &amp;#8220;Securities Act&amp;#8221;) and the
   Securities Exchange Act of 1934, as amended (the &amp;#8220;Exchange Act&amp;#8221;), as well as Industry Guide 2. The
   amendments are designed to modernize and update oil and gas disclosure requirements to align them
   with current practices and changes in technology. The disclosure requirements are effective for
   registration statements filed on or after January&amp;#160;1, 2010 and for annual financial statements filed
   on or after December&amp;#160;31, 2009. The Company is currently evaluating the impact that the Final Rule
   may have on its consolidated financial statements.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;In April&amp;#160;2009, the FASB issued FASB Staff Position
   No.&amp;#160;157-4, &lt;i&gt;Determining Fair Value When the Volume and Level
   of Activity for the Asset or Liability Have Significantly Decreased
   and Identifying Transactions That Are Not Orderly &lt;/i&gt;(&amp;#8220;FSP 157-4&amp;#8221;). FSP 157-4 provides additional
   guidance for determining whether a market for a financial asset is not active and a transaction is
   not distressed for fair value measurements under FAS 157. The provisions of this FSP are effective
   for financial statements issued for interim and annual periods ending after June&amp;#160;15, 2009 and
   became effective for the Company in the quarter ended June&amp;#160;30, 2009. The adoption of FSP 157-4 did
   not have a material impact on the Company.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;In April&amp;#160;2009, the FASB issued FASB Staff Position No.&amp;#160;107-1 and APB No.&amp;#160;28-1, &lt;i&gt;Interim
   Disclosures about Fair Value of Financial Instruments &lt;/i&gt;(&amp;#8220;FSP 107-1&amp;#8221;). This FSP increases the
   frequency of fair value disclosures as required by FAS 107, &lt;i&gt;Disclosures about Fair Value of
   Financial Instruments&lt;/i&gt;, from annual only to quarterly reporting periods. The provisions of this FSP
   are effective for financial statements issued for interim and annual periods ending after June&amp;#160;15,
   2009 and became effective for the Company in the quarter ended June&amp;#160;30, 2009. The adoption of FSP
   107-1 did not have a material impact on the Company.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;In June&amp;#160;2009, the FASB issued Statement of Financial Accounting Standards No.&amp;#160;167, &lt;i&gt;Amendments
   to FASB Interpretation No.&amp;#160;46(R) &lt;/i&gt;(&amp;#8220;FAS 167&amp;#8221;). FAS 167 retains the scope of FASB Interpretation No.
   46(R) with the addition of entities previously considered qualifying special-purpose entities and
   requires ongoing reassessments of whether an enterprise is the primary beneficiary of a variable
   interest entity. Before this Statement, FASB Interpretation No.&amp;#160;46(R) required reconsideration of
   whether an enterprise is the primary beneficiary of a variable interest entity only when specific
   events occurred. FAS 167 is effective as of the beginning of each
   reporting entity&amp;#8217;s first annual reporting period that begins after November&amp;#160;15, 2009, for
       interim periods within that first annual reporting period, and for interim and annual reporting
       periods thereafter and will become effective for the Company on January&amp;#160;1, 2010. The adoption of
       FAS 167 is not expected to have a material impact on the Company.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;In June&amp;#160;2009, the FASB issued Statement of Financial Accounting Standards No.&amp;#160;168, &lt;i&gt;The FASB
       Accounting Standards Codification and the Hierarchy of Generally Accepted Accounting Principles &amp;#8212;
       a replacement of FASB Statement No.&amp;#160;162 &lt;/i&gt;(&amp;#8220;FAS 168&amp;#8221;). On the effective date of FAS 168, the &lt;i&gt;FASB
       Accounitng Standards Codification &lt;/i&gt;(&amp;#8220;Codification&amp;#8221;) will become the source of authoritative U.S.
   generally accepted accounting principles. Following FAS 168, the FASB will not issue new standards
       in the form of Statements, FASB Staff Positions or EITF Abstracts. Instead, it will issue
       Accounting Standards Updates to update the Codification. FAS 168 is effective for financial
       statements issued for interim and annual periods ending after September&amp;#160;15, 2009 and will be
       effective for the Company in the quarter ending September&amp;#160;30, 2009. The adoption of FAS 168 will
       not have a material impact on the Company.
   &lt;/div&gt;
   &lt;/div&gt;
   &lt;/body&gt;

   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The Company&amp;#8217;s revenues, operating profits and identifiable assets are primarily attributable
   to four business segments: (i)&amp;#160;contract drilling of oil and natural gas wells, (ii)&amp;#160;pressure
   pumping services, (iii)&amp;#160;drilling and completion fluid services and (iv)&amp;#160;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&amp;#8217;s chief operating decision
   maker. The results of operations in these segments are regularly reviewed by the chief operating
   decision maker for purposes of determining resource allocation and assessing performance. Separate
   financial data for each of our four business segments is provided in the table below (in
   thousands):

   Energy, Inc. (the &amp;#8220;Company&amp;#8221;) and its wholly-owned subsidiaries. All significant intercompany
   accounts and transactions have been eliminated. Except for wholly-owned subsidiaries, the Company
   has no controlling financial interests in any entity which would require consolidation.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The unaudited interim consolidated financial statements have been prepared by management of
   the Company 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&amp;#160;31, 2008, as presented herein, was derived from
   the audited consolidated 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&amp;#8217;s Annual Report on Form 10-K for the
   fiscal year ended December&amp;#160;31, 2008. The results of operations for the three and six months ended
   June&amp;#160;30, 2009 are not necessarily indicative of the results to be expected for the full year.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The U.S. dollar is the functional currency for all of the Company&amp;#8217;s operations except for its
   Canadian operations, which uses the Canadian dollar as its functional currency. The effects of
   exchange rate changes are reflected in accumulated other comprehensive income, which is a separate
   component of stockholders&amp;#8217; equity.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The
   Company has performed an evaluation of subsequent events through
   August&amp;#160;4, 2009 at the time of issuance of the unaudited consolidated financial statements.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The Company provides a dual presentation of its net income (loss)&amp;#160;per common share in its
   Unaudited Consolidated Statements of Income: Basic net income (loss)&amp;#160;per common share (&amp;#8220;Basic
   EPS&amp;#8221;) and diluted net income (loss)&amp;#160;per common share (&amp;#8220;Diluted EPS&amp;#8221;). The Company adopted the
   provisions of FASB Staff Position No.&amp;#160;EITF 03-6-1, &lt;i&gt;Determining Whether Instruments Granted in
   Share-Based Payment Transactions Are Participating Securities &lt;/i&gt;(&amp;#8220;FSP EITF 03-6-1&amp;#8221;) in the quarter
   ended March&amp;#160;31, 2009. FSP EITF 03-6-1 clarifies that share-based payment awards that entitle their
   holders to receive non-forfeitable dividends before vesting should be considered participating
   securities and, as such, should be included in the calculation of earnings-per-share using the
   two-class method. All earnings per share data presented for the three and six months ended June
   30, 2008 has been adjusted retrospectively to conform with the provisions of FSP EITF 03-6-1. The
   impact of this retrospective application was to reduce Basic EPS for the three months ended June
   30, 2008 by $0.01 and to reduce Basic EPS and Diluted EPS for the six months ended June&amp;#160;30, 2008 by
   $0.01.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;Basic EPS excludes dilution and is computed by first allocating earnings between common
   stockholders and holders of non-vested shares of restricted stock. Basic EPS is then determined by
   dividing the earnings attributable to common stockholders by the weighted average number of common
   shares outstanding during the period, excluding non-vested shares of
   restricted stock.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;Diluted EPS is based on the weighted average number of common shares outstanding plus the
   dilutive effect of potential common shares, including stock options, non-vested shares of
   restricted stock and restricted stock units. The dilutive effect of stock options and restricted
   stock units is determined based on the treasury stock method. The dilutive effect of non-vested
   shares of restricted stock is based on the more dilutive of the treasury stock method or the
   two-class method, assuming a reallocation of undistributed earnings to common stockholders after
   considering the dilutive effect of potential common shares other than non-vested shares of
   restricted stock.

   &lt;div align="left" style="font-size: 10pt; margin-top: 12pt"&gt;&lt;b&gt;11. Recently Issued Accounting Standards&lt;/b&gt;
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;In
   September 2006, the FASB issued Statement No. 157, &lt;i&gt;Fair Value
   Measurements&lt;/i&gt; (&amp;#8220;FAS 157&amp;#8221;).
   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 was limited to financial assets and liabilities and
   became effective on January 1, 2008 for the Company.  The impact of the initial application
   of FAS 157 was not material.  On January 1, 2009, the Company adopted FAS 157 on a prospective
   basis for non-financial assets and liabilities that are not measured at fair value on a
   recurring basis.  The application of FAS 157 to the Company&amp;#8217;s non-financial assets and
   liabilities is primarily 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 has not had a material impact on the Company.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;In December&amp;#160;2007, the FASB issued Statement No.&amp;#160;141(R), &lt;i&gt;Business Combinations &lt;/i&gt;(&amp;#8220;FAS 141(R)&amp;#8221;)
   and Statement No.&amp;#160;160, &lt;i&gt;Noncontrolling Interests in Consolidated Financial Statements, an amendment
   of ARB No.&amp;#160;51 &lt;/i&gt;(&amp;#8220;FAS 160&amp;#8221;). FAS 141(R) is a revision of Statement No.&amp;#160;141, &lt;i&gt;Business Combinations&lt;/i&gt;,
   and calls for significant changes from current practice in accounting for business combinations.
   FAS 141(R) is effective for business combinations for which the acquisition date is on or after the
   beginning of the first annual reporting period beginning on or after December&amp;#160;15, 2008. FAS 160
   amends ARB 51 to establish accounting and reporting standards for the non-controlling interest in a
   subsidiary and for the deconsolidation of a subsidiary. FAS 160 is effective for fiscal years
   beginning on or after December&amp;#160;15, 2008. Both FAS 141(R) and FAS 160 became effective for the
   Company on January&amp;#160;1, 2009. The application of FAS 141(R) and FAS 160 did not have a material
   impact on the Company.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;In June&amp;#160;2008, the FASB issued FASB Staff Position No.&amp;#160;EITF 03-6-1, &lt;i&gt;Determining Whether
   Instruments Granted in Share-Based Payment Transactions Are Participating Securities &lt;/i&gt;(&amp;#8220;FSP EITF
   03-6-1&amp;#8221;). FSP EITF 03-6-1 clarifies that share-based payment awards that entitle their holders to
   receive non-forfeitable 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&amp;#8217;s share-based payment awards entitle the holders to receive
   non-forfeitable dividends. FSP EITF 03-6-1 is effective for financial statements issued for fiscal
   years beginning after December&amp;#160;15, 2008, as well as interim periods within those years and became
   effective for the Company on January&amp;#160;1, 2009. The impact of the adoption of FSP EITF 03-6-1 is
   discussed in Note 1.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;In December&amp;#160;2008, the SEC issued a Final Rule, &lt;i&gt;Modernization of Oil and Gas Reporting &lt;/i&gt;(&amp;#8220;Final
   Rule&amp;#8221;). The Final Rule revises certain oil and gas reporting disclosures in Regulation&amp;#160;S-K and
   Regulation&amp;#160;S-X under the Securities Act of 1933, as amended (the &amp;#8220;Securities Act&amp;#8221;) and the
   Securities Exchange Act of 1934, as amended (the &amp;#8220;Exchange Act&amp;#8221;), as well as Industry Guide 2. The
   amendments are designed to modernize and update oil and gas disclosure requirements to align them
   with current practices and changes in technology. The disclosure requirements are effective for
   registration statements filed on or after January&amp;#160;1, 2010 and for annual financial statements filed
   on or after December&amp;#160;31, 2009. The Company is currently evaluating the impact that the Final Rule
   may have on its consolidated financial statements.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;In April&amp;#160;2009, the FASB issued FASB Staff Position
   No.&amp;#160;157-4, &lt;i&gt;Determining Fair Value When the Volume and Level
   of Activity for the Asset or Liability Have Significantly Decreased
   and Identifying Transactions That Are Not Orderly &lt;/i&gt;(&amp;#8220;FSP 157-4&amp;#8221;). FSP 157-4 provides additional
   guidance for determining whether a market for a financial asset is not active and a transaction is
   not distressed for fair value measurements under FAS 157. The provisions of this FSP are effective
   for financial statements issued for interim and annual periods ending after June&amp;#160;15, 2009 and
   became effective for the Company in the quarter ended June&amp;#160;30, 2009. The adoption of FSP 157-4 did
   not have a material impact on the Company.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;In April&amp;#160;2009, the FASB issued FASB Staff Position No.&amp;#160;107-1 and APB No.&amp;#160;28-1, &lt;i&gt;Interim
   Disclosures about Fair Value of Financial Instruments &lt;/i&gt;(&amp;#8220;FSP 107-1&amp;#8221;). This FSP increases the
   frequency of fair value disclosures as required by FAS 107, &lt;i&gt;Disclosures about Fair Value of
   Financial Instruments&lt;/i&gt;, from annual only to quarterly reporting periods. The provisions of this FSP
   are effective for financial statements issued for interim and annual periods ending after June&amp;#160;15,
   2009 and became effective for the Company in the quarter ended June&amp;#160;30, 2009. The adoption of FSP
   107-1 did not have a material impact on the Company.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;In June&amp;#160;2009, the FASB issued Statement of Financial Accounting Standards No.&amp;#160;167, &lt;i&gt;Amendments
   to FASB Interpretation No.&amp;#160;46(R) &lt;/i&gt;(&amp;#8220;FAS 167&amp;#8221;). FAS 167 retains the scope of FASB Interpretation No.
   46(R) with the addition of entities previously considered qualifying special-purpose entities and
   requires ongoing reassessments of whether an enterprise is the primary beneficiary of a variable
   interest entity. Before this Statement, FASB Interpretation No.&amp;#160;46(R) required reconsideration of
   whether an enterprise is the primary beneficiary of a variable interest entity only when specific
   events occurred. FAS 167 is effective as of the beginning of each
   reporting entity&amp;#8217;s first annual reporting period that begins after November&amp;#160;15, 2009, for
       interim periods within that first annual reporting period, and for interim and annual reporting
       periods thereafter and will become effective for the Company on January&amp;#160;1, 2010. The adoption of
       FAS 167 is not expected to have a material impact on the Company.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;In June&amp;#160;2009, the FASB issued Statement of Financial Accounting Standards No.&amp;#160;168, &lt;i&gt;The FASB
       Accounting Standards Codification and the Hierarchy of Generally Accepted Accounting Principles &amp;#8212;
       a replacement of FASB Statement No.&amp;#160;162 &lt;/i&gt;(&amp;#8220;FAS 168&amp;#8221;). On the effective date of FAS 168, the &lt;i&gt;FASB
       Accounitng Standards Codification &lt;/i&gt;(&amp;#8220;Codification&amp;#8221;) will become the source of authoritative U.S.
   generally accepted accounting principles. Following FAS 168, the FASB will not issue new standards
       in the form of Statements, FASB Staff Positions or EITF Abstracts. Instead, it will issue
       Accounting Standards Updates to update the Codification. FAS 168 is effective for financial
       statements issued for interim and annual periods ending after September&amp;#160;15, 2009 and will be
       effective for the Company in the quarter ending September&amp;#160;30, 2009. The adoption of FAS 168 will
       not have a material impact on the Company.
   &lt;/div&gt;
   &lt;/div&gt;

   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;Goodwill is evaluated at least annually to determine if the fair value of recorded goodwill
   has decreased below its carrying value. For purposes of impairment testing, goodwill is evaluated
   at the reporting unit level. The Company&amp;#8217;s reporting units for impairment testing have been
   determined to be its operating segments.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;As
   of June&amp;#160;30, 2009 and December&amp;#160;31, 2008 the Company had
   goodwill of $86.2&amp;#160;million, all in its
   contract drilling reporting unit. In the event that market conditions remain weak, the Company may
   be required to record an impairment of goodwill in its contract drilling reporting unit in the
   future, and such impairment could be material.

   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The Company entered into an unsecured revolving line of credit (&amp;#8220;LOC&amp;#8221;) on March&amp;#160;20, 2009 with
   a maximum borrowing  capacity of $220&amp;#160;million, including a letter of credit
   sublimit of $150&amp;#160;million and a swing line sublimit of $40&amp;#160;million. In addition, the aggregate
   borrowing and letter of credit capacity under the LOC may, subject to the terms and conditions set
   forth therein
   including the receipt of additional commitments from lenders, be increased up to a maximum
       amount not to exceed $450&amp;#160;million. On June&amp;#160;19, 2009, the Company entered into a Commitment
       Increase and Joinder Agreement to increase the maximum borrowing capacity to $240&amp;#160;million.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;Interest is paid on the outstanding principal amount of LOC borrowings at a floating rate
       based on, at the Company&amp;#8217;s election, LIBOR or a base rate. The margin on LIBOR loans ranges from
       3.00% to 4.00% and the margin on base rate loans ranges from 2.00% to 3.00%, based on the Company&amp;#8217;s
       debt to capitalization ratio. At June&amp;#160;30, 2009, the margin on LIBOR loans would have been 3.00%
   and the margin on base rate loans would have been 2.00%. Any outstanding borrowings must be repaid
       at maturity on January&amp;#160;31, 2012 and letters of credit may remain in effect up to six months after
       such maturity date. This LOC facility includes various fees, including a commitment fee on the
       actual daily unused commitment (the commitment fee rate was 1.00% at June&amp;#160;30, 2009).
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The Company incurred line of credit issuance costs of approximately $6.2&amp;#160;million during the
       six months ended June&amp;#160;30, 2009 in connection with the LOC. These costs are being amortized over
       the contractual term of the LOC as an adjustment to interest expense.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;There are customary representations, warranties, 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&amp;#160;30, 2009, the
       Company had no borrowings outstanding under the LOC. The Company had $46.3&amp;#160;million in letters of
       credit outstanding at June&amp;#160;30, 2009 and, as a result, had available borrowing capacity of
       approximately $194&amp;#160;million at that date. Each domestic subsidiary of the Company has
       unconditionally guaranteed the existing and future obligations of the Company and each other
       guarantor under the LOC and related loan documents, as well as obligations of the Company and its
       subsidiaries under any interest rate swap contracts that may be entered into with lenders party to the LOC.
   &lt;/div&gt;
   &lt;/div&gt;

   amount of $46.3&amp;#160;million for the benefit of various insurance companies as collateral for
   retrospective premiums and retained losses which could become payable under the terms of the
   underlying insurance contracts. These letters of credit expire at various times during the

   under the letters of credit.

   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The Company recognizes the cost of share-based awards under the fair-value-based method. The
   Company uses share-based awards to compensate employees and non-employee directors. All
   share-based awards have been equity instruments in the form of stock options, restricted stock or
   restricted stock units and have included service and, in certain cases, performance conditions.
   The Company issues shares of common stock when vested stock options are exercised, when restricted
   stock is granted and when restricted stock units vest.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&lt;i&gt;Stock Options. &lt;/i&gt;The Company estimates the grant date fair values of stock options using the
   Black-Scholes-Merton valuation model (&amp;#8220;Black-Scholes&amp;#8221;). Volatility assumptions are based on the
   historic volatility of the Company&amp;#8217;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&amp;#8217;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&amp;#160;30, 2009 and 2008 follow:

       when the awards were made. Non-vested shares are subject to forfeiture for failure to fulfill
       service conditions and, in certain cases, performance conditions. Non-forfeitable dividends are
       paid on non-vested shares of restricted stock. For restricted stock awards made prior to 2008, the
       Company used the &amp;#8220;graded-vesting&amp;#8221; attribution method to recognize periodic compensation cost over
       the vesting period. For restricted stock awards made in 2008 and thereafter, the Company uses the
       straight-line method to recognize periodic compensation cost over the vesting period.

   (&amp;#8220;Program&amp;#8221;), authorizing purchases of up to $250&amp;#160;million of the Company&amp;#8217;s common stock in open
       market or privately negotiated transactions. During the six months ended June&amp;#160;30, 2009, the
       Company purchased 3,324 shares of its common stock under the Program at a cost of approximately
   $46,000. As of June&amp;#160;30, 2009, the Company is authorized to purchase approximately $113&amp;#160;million of
       the Company&amp;#8217;s outstanding common stock under the Program. Shares purchased under the Program are
       accounted for as treasury stock.

   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The Company purchased 85,817 shares of stock from employees during the six months ended June
       30, 2009 on dates that corresponded with the vesting of restricted stock. These shares were
       purchased at fair market value to provide employees with the funds necessary to satisfy payroll tax
       withholding obligations and have been accounted for as treasury stock. The total purchase price
       for these shares was approximately $1.1&amp;#160;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.
