     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 31, 2009, 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’s Annual Report on Form 10-K for the fiscal year ended December 31, 2009. The results of operations for the three and nine months ended September 30, 2010 are not necessarily indicative of the results to be expected for the full year.
     The U.S. dollar is the functional currency for all of the Company’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’ equity.
     Certain reclassifications have been made to the 2009 consolidated financial statements in order for them to conform with the 2010 presentation.
     The carrying values of cash and cash equivalents, trade receivables and accounts payable approximate fair value.
     The Company provides a dual presentation of its net income per common share in its unaudited consolidated statements of operations: Basic net income per common share (“Basic EPS”) and diluted net income per common share (“Diluted EPS”).
     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.
     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.

2. Discontinued Operations
     On January 20, 2010, the Company exited the drilling and completion fluids business, which had previously been presented as one of the Company’s reportable operating segments. On that date, the Company’s wholly owned subsidiary, Ambar Lone Star Fluids Services LLC, completed the sale of substantially all of its assets, excluding billed accounts receivable. The sales price was approximately $42.6 million. Upon the Company’s exit from the drilling and completion fluids business, the Company classified its drilling and completion fluids operating segment as a discontinued operation. Accordingly, the results of operations of this business have been reclassified and presented as results of discontinued operations for all periods presented in these consolidated financial statements. As of December 31, 2009, the assets to be disposed of were considered held for sale and were presented separately within current assets under the caption “Assets held for sale” in the consolidated balance sheet. Upon being classified as held for sale, the assets to be disposed of were adjusted to fair value less estimated costs to sell resulting in an impairment loss of $1.9 million. Due to the fact that the carrying value of the assets had been adjusted to net realizable value, no additional gain or loss was recognized in connection with the sale in 2010.

3. Acquisitions
     On October 1, 2010, two subsidiaries of the Company, Universal Pressure Pumping, Inc. (“UPP”) and Universal Wireline, Inc. completed the acquisition of certain assets from Key Energy Pressure Pumping Services, LLC (“Key Pressure Pumping”) and Key Electric Wireline Services, LLC (together with Key Pressure Pumping, the “Sellers”) relating to the businesses of providing pressure pumping services and electric wireline services to participants in the oil and natural gas industry for an approximate aggregate purchase price of $238 million in cash (the “Purchase Price”). This acquisition expands the Company’s pressure pumping operations to additional markets primarily in Texas. The Purchase Price, which was funded through a combination of cash on hand and a $200 million draw on the Company’s revolving credit facility, is subject to certain adjustments based on closing inventory. The Company is in the process of determining the fair values of the assets acquired and liabilities assumed and the results of operations for these acquired businesses will be included in the Company’s consolidated results of operations beginning in the quarter ending December 31, 2010. The acquisition was effected pursuant to an Asset Purchase Agreement dated July 2, 2010, as amended, modified and supplemented, by and among Patterson-UTI Energy, Inc., UPP (formerly known as Portofino Acquisition Company), Sellers and Key Energy Services, Inc., a Maryland corporation.
4. Stock-based Compensation
     The Company uses share-based payments to compensate employees and non-employee directors. The Company recognizes the cost of share-based payments under the fair-value-based method. Share-based awards consist of equity instruments in the form of stock options, restricted stock or restricted stock units and have included service and, in certain cases, performance conditions. Additionally, share-based awards also include both cash-settled and share-settled performance unit awards. Cash-settled performance unit awards are accounted for as liability awards. Share-settled performance unit awards are accounted for as equity awards. The Company issues shares of common stock when vested stock options are exercised, when restricted stock is granted and when restricted stock units and share-settled performance unit awards vest.
     Stock Options. The Company estimates the grant date fair values of stock options using the Black-Scholes-Merton valuation model. Volatility assumptions are based on the historic volatility of the Company’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’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 nine month periods ended September 30, 2010 and 2009 follow:
                                 
    Three Months Ended   Nine Months Ended
    September 30,   September 30,
    2010   2009   2010   2009

     Restricted Stock. For all restricted stock awards to date, shares of common stock were issued 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 uses the “graded-vesting” 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.

     Restricted Stock Units. For all restricted stock unit awards made to date, shares of common stock are not issued until the units vest. Restricted stock units are subject to forfeiture for failure to fulfill service conditions. Non-forfeitable cash dividend equivalents are paid on non-vested restricted stock units.

     Performance Unit Awards. On April 28, 2009, the Company granted cash-settled performance unit awards to certain executive officers (the “2009 Performance Units”). The 2009 Performance Units provide for those executive officers to receive a cash payment upon the achievement of certain performance goals established by the Company during a specified period. The performance period for the 2009 Performance Units is the period from April 1, 2009 through March 31, 2012, but can extend through March 31, 2014 in certain circumstances. The performance goals for the 2009 Performance Units are tied to the Company’s total shareholder return for the performance period as compared to total shareholder return for a peer group determined by the Compensation Committee of the Board of Directors. These goals are considered to be market conditions under the relevant accounting standards and the market conditions are factored into the determination of the fair value of the performance units. Generally, the recipients will receive a base payment if the Company’s total shareholder return is positive and, when compared to the peer group, is at or above the 25th percentile but less than the 50th percentile, two times the base if at or above the 50th percentile but less than the 75th percentile, and four times the base if at the 75th percentile or higher. The total base amount with respect to the 2009 Performance Units is approximately $1.7 million. As the 2009 Performance Units are to be settled in cash at the end of the performance period, the Company’s pro-rated

obligation is measured at estimated fair value at the end of each reporting period using a Monte Carlo simulation model. As of September 30, 2010 this pro-rated obligation was approximately $1.7 million.
     On April 27, 2010, the Company granted stock-settled performance unit awards to certain executive officers (the “2010 Performance Units”). The 2010 Performance Units provide for those executive officers to receive a grant of shares of stock upon the achievement of certain performance goals established by the Company during a specified period. The performance period for the 2010 Performance Units is the period from April 1, 2010 through March 31, 2013, but can extend through March 31, 2015 in certain circumstances. The performance goals for the 2010 Performance Units are tied to the Company’s total shareholder return for the performance period as compared to total shareholder return for a peer group determined by the Compensation Committee of the Board of Directors. These goals are considered to be market conditions under the relevant accounting standards and the market conditions are factored into the determination of the fair value of the performance units. Generally, the recipients will receive a base number of shares if the Company’s total shareholder return is positive and, when compared to the peer group, is at or above the 25th percentile but less than the 50th percentile, two times the base if at or above the 50th percentile but less than the 75th percentile, and four times the base if at the 75th percentile or higher. The grant of shares when achievement is between the 25th and 75th percentile will be determined on a pro-rata basis. The total base number of shares with respect to the 2010 Performance Units is 89,375 shares. Because the 2010 Performance Units are stock-settled awards, they are accounted for as equity awards and measured at fair value on the date of grant. The fair value of the 2010 Performance Units as of the date of grant was approximately $3.1 million using a Monte Carlo simulation model. This amount will be recognized on a straight-line basis over the performance period. During the three and nine months ended September 30, 2010, the Company recognized approximately $260,000 and $520,000, respectively, in expense related to the 2010 Performance Units.

     During the nine months ended September 30, 2010, the Company sold certain rights to explore and develop zones deeper than depths that it generally targets for certain of the oil and natural gas properties in which it has working interests. The proceeds from this sale were approximately $22.3 million and the sale resulted in a gain on disposal of $20.1 million.

6. Business Segments
     The Company’s revenues, operating profits and identifiable assets are primarily attributable to three business segments: (i) contract drilling of oil and natural gas wells, (ii) pressure pumping services and (iii) the investment, on a working interest basis, in oil and natural gas properties. Each of these segments represents a distinct type of business. These segments have separate management teams which report to the Company’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. As discussed in Note 2, in January 2010 the Company exited the drilling and completion fluids business which previously was reported as a business segment. Operating results for that business for the three and nine months ended September 30, 2010 and 2009 are presented as discontinued operations in the consolidated statements of operations. Separate financial data for each of our business segments is provided in the table below (in thousands):

7. Goodwill
     Goodwill is evaluated at least annually to determine if the fair value of recorded goodwill has decreased below its carrying value. The Company performs this annual evaluation in the fourth quarter of each year. For purposes of impairment testing, goodwill is evaluated at the reporting unit level. The Company’s reporting units for impairment testing have been determined to be its operating segments.
     As of September 30, 2010 and December 31, 2009, the Company had goodwill of $86.2 million, all within its contract drilling reporting unit. In the event that market conditions weaken, 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.

10. Long Term Debt
     On July 2, 2010, the Company entered into a 364-Day Credit Agreement (the “364-Day Credit Agreement”) among the Company, as borrower, and Wells Fargo Bank, N.A., as administrative agent and lender. The 364-Day Credit Agreement was a committed senior unsecured single draw term loan credit facility that permitted a borrowing of up to $250 million; provided that the loan must be drawn no later than September 30, 2010 or, if an additional fee was paid, October 30, 2010. The maturity date under the 364-Day Credit Agreement was 364 days after the date on which the closing conditions under the 364-Day Credit Agreement were met. The loan was not drawn as of September 30, 2010 and the 364-Day Credit Agreement expired at that time.
     On August 19, 2010, the Company entered into a Credit Agreement (the “2010 Credit Agreement”) among the Company, as borrower, Wells Fargo Bank, N.A., as administrative agent, letter of credit issuer, swing line lender and lender, and each of the other letter of credit issuer and lender parties thereto. The 2010 Credit Agreement is a committed senior unsecured credit facility that permits aggregate borrowings of up to $500 million pursuant to a revolving credit facility and a term loan facility. The 2010 Credit Agreement replaced a previous unsecured revolving credit facility.

Table of Contents

     The revolving credit facility permits aggregate borrowings of up to, at any time outstanding, $400 million, which contains a letter of credit facility that, at any time outstanding, is limited to $150 million and a swing line facility that, at any time outstanding, is limited to $40 million. Subject to customary conditions, the Company may request that the lenders’ aggregate commitments with respect to the revolving credit facility be increased by up to $100 million, not to exceed total commitments of $500 million. The maturity date for the revolving facility is August 19, 2013.
     The term loan facility provided for a loan of $100 million which was funded on August 19, 2010. The term loan facility is payable in quarterly principal installments commencing November 19, 2010, and the installment amounts vary from 1.25% of the original principal amount for each of the first four quarterly installments, 2.50% of the original principal amount for each of the subsequent eight quarterly installments, 5.00% of the original principal amount for the next subsequent three quarterly installments and the remainder at maturity. The maturity date for the term loan facility is August 19, 2014.
     Loans under the 2010 Credit Agreement bear interest by reference, at the Company’s election, to the LIBOR rate or base rate, provided, that swing line loans bear interest by reference only to the base rate. The applicable margin on LIBOR rate loans varies from 2.75% to 3.75% and the applicable margin on base rate loans varies from 1.75% to 2.75%, in each case determined based upon the Company’s debt to capitalization ratio. As of September 30, 2010, the applicable margin on LIBOR rate loans was 2.75% and the applicable margin on base rate loans was 1.75%. A letter of credit fee is payable by the Company equal to the applicable margin for LIBOR rate loans times the daily amount available to be drawn under outstanding letters of credit. The commitment fee payable to the lenders for the unused portion of the revolving credit facility varies from 0.50% to 0.75% based upon the Company’s debt to capitalization ratio and was 0.50% as of September 30, 2010.
     Each domestic subsidiary of the Company other than any immaterial subsidiary has unconditionally guaranteed all existing and future indebtedness and liabilities of the Company and the other guarantors arising under the 2010 Credit Agreement and other loan documents. Such guarantees also cover obligations of the Company and any subsidiary of the Company arising under any interest rate swap contract with any person while such person is a lender or affiliate of a lender under the 2010 Credit Agreement.
     The 2010 Credit Agreement contains customary representations, warranties, indemnities and affirmative and negative covenants. The 2010 Credit Agreement also requires compliance with two financial covenants. The Company must not permit its debt to capitalization ratio to exceed 45% at any time. The 2010 Credit Agreement generally defines the debt to capitalization ratio as the ratio of (a) total borrowed money indebtedness to (b) the sum of such indebtedness plus consolidated net worth, with consolidated net worth determined as of the last day of the most recently ended fiscal quarter. The Company also must not permit the interest coverage ratio as of the last day of a fiscal quarter to be less than 3.00 to 1.00. The 2010 Credit Agreement generally defines the interest coverage ratio as the ratio of earnings before interest, taxes, depreciation and amortization (“EBITDA”) of the four prior fiscal quarters to interest charges for the same period. 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 September 30, 2010, the Company had $100 million outstanding under the term loan facility at an interest rate of 3.125% and no borrowings outstanding under the revolving credit facility. The Company had $41.2 million in letters of credit outstanding at September 30, 2010 and, as a result, had available borrowing capacity of approximately $359 million at that date.

of the underlying insurance contracts. These letters of credit expire annually at various times during the year and are typically renewed. As of September 30, 2010, no amounts had been drawn under the letters of credit.
     As of September 30, 2010, the Company had commitments to purchase approximately $250 million of major equipment.
     The Company is party to various legal proceedings arising in the normal course of its business. The Company does not believe that the outcome of these proceedings, either individually or in the aggregate, will have a material adverse effect on its financial condition, results of operations or cash flows.

  $ 0.15     $ 23,087  
 
           
     On October 27, 2010, the Company’s Board of Directors approved a cash dividend on its common stock in the amount of $0.05 per share to be paid on December 30, 2010 to holders of record as of December 15, 2010. The amount and timing of all future dividend payments, if any, is subject to the discretion of the Board of Directors and will depend upon business conditions, results of operations, financial condition, terms of the Company’s credit facilities and other factors.
     On August 1, 2007, the Company’s Board of Directors approved a stock buyback program authorizing purchases of up to $250 million of the Company’s common stock in open market or privately negotiated transactions. During the nine months ended September 30, 2010, the Company purchased 8,743 shares of its common stock under the program at a cost of approximately $123,000. As of September 30, 2010, the Company is authorized to purchase approximately $113 million of the Company’s outstanding common stock under the program. Shares purchased under the program are accounted for as treasury stock.
     The Company purchased 116,819 shares of treasury stock from employees during the nine months ended September 30, 2010. These shares were purchased at fair market value upon the vesting of restricted stock to provide the employees with the funds necessary to satisfy payroll tax withholding obligations. The total purchase price for these shares was approximately $1.7 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 stock buyback program.
13. Income Taxes
     On January 1, 2010, the Company converted its Canadian operations from a Canadian branch to a controlled foreign corporation for Federal income tax purposes. Because the statutory tax rates in Canada are lower than those in the United States, this transaction triggered a $5.1 million reduction in the Company’s deferred tax liabilities, which is being amortized as a reduction to deferred income tax expense over the weighted average remaining useful life of the Canadian assets.
     As a result of the above conversion, the Company’s Canadian assets are no longer subject to United States taxation, provided that the related unremitted earnings are permanently reinvested in Canada. Effective January 1, 2010, the Company has elected to permanently reinvest these unremitted earnings in Canada, and it intends to do so for the foreseeable future. As a result, no deferred United States Federal or state income taxes have been provided on such unremitted foreign earnings, which totaled approximately $1.7 million as of September 30, 2010.

14. Recently Issued Accounting Standards
     In June 2009, the FASB issued a new accounting standard that amends the accounting and disclosure requirements for the consolidation of variable interest entities. This new standard removes the previously existing exception from applying consolidation guidance to qualifying special-purpose entities and requires ongoing reassessments of whether an enterprise is the primary beneficiary of a variable interest entity. Before this new standard, generally accepted accounting principles required reconsideration of whether an enterprise is the primary beneficiary of a variable interest entity only when specific events occurred. This new standard is effective as of the beginning of each reporting entity’s first annual reporting period that begins after November 15, 2009, for interim periods within that first annual reporting period, and for interim and annual reporting periods thereafter. This new standard became effective for the Company on January 1, 2010. The adoption of this standard did not impact the Company’s consolidated financial statements.
     In October 2009, the FASB issued a new accounting standard that addresses the accounting for multiple-deliverable revenue arrangements to enable vendors to account for deliverables separately rather than as a combined unit. This new standard addresses how to separate deliverables and how to measure and allocate arrangement consideration to one or more units of accounting. Existing accounting standards require a vendor to use objective and reliable evidence of fair value for the undelivered items or the residual method to separate deliverables in a multiple-deliverable arrangement. Under the new standard, it is expected that multiple-deliverable arrangements will be separated in more circumstances than under current requirements. The new standard establishes a hierarchy for determining the selling price of a deliverable for purposes of allocating revenue to multiple deliverables. The selling price used will be based on vendor-specific objective evidence if available, third-party evidence if vendor-specific objective evidence is not available, or estimated selling price if neither vendor-specific objective evidence nor third-party evidence is available. The new standard must be prospectively applied to all revenue arrangements entered into in fiscal years beginning on or after June 15, 2010 and will be effective for the Company on January 1, 2011. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial position, results of operations or cash flows.
15. Subsequent Events
     On October 5, 2010, the Company completed an issuance and sale of $300 million in aggregate principal amount of its 4.97% Series A Senior Notes due October 5, 2020 (the “Notes”) in a private placement. A portion of the proceeds from the Notes were used to repay a $200 million borrowing on the Company’s revolving credit facility which had been drawn to fund a portion of the acquisition that closed on October 1, 2010 as discussed in Note 3. The Notes are senior unsecured obligations of the Company, which rank equally in right of payment with all other unsubordinated indebtedness of the Company. The Notes are guaranteed on a senior unsecured basis by each of the existing domestic subsidiaries of the Company other than immaterial subsidiaries.
     The Notes bear interest at a rate of 4.97% per annum and were priced at 100% of the principal amount of the Notes. The Company will pay interest on the Notes on April 5 and October 5 of each year commencing on April 5, 2011. The Notes will mature on October 5, 2020. The Notes are prepayable at the Company’s option, in whole or in part, provided that in the case of a partial prepayment, prepayment must be in an amount not less than 5% of the aggregate principal amount of the Notes then outstanding, at any time and from time to time at 100% of the principal amount prepaid, plus accrued and unpaid interest to the prepayment date, plus a “make-whole” premium as specified in the note purchase agreement. The Company must offer to prepay the Notes upon the occurrence of any change of control. In addition, the Company must offer to prepay the Notes upon the occurrence of certain asset dispositions if the proceeds therefrom are not timely reinvested in productive assets. If any offer to prepay is accepted, the purchase price of each prepaid Note is 100% of the principal amount thereof, plus accrued and unpaid interest thereon to the prepayment date.
     The note purchase agreement requires compliance with two financial covenants. The Company must not permit its debt to capitalization ratio to exceed 50% at any time. The note purchase agreement generally defines the debt to capitalization ratio as the ratio of (a) total borrowed money indebtedness to (b) the sum of such indebtedness plus consolidated net worth, with consolidated net worth determined as of the last day of the most recently ended fiscal quarter. The Company also must not permit the interest coverage ratio as of the last day of a fiscal quarter to be less than 2.50 to 1.00. The note purchase agreement generally defines the interest coverage ratio as the ratio for the four prior quarters of EBITDA to interest charges.
     Events of default under the note purchase agreement include failure to pay principal or interest when due, failure to comply with the financial and operational covenants, a cross default event, a judgment in excess of a threshold event, the guaranty agreement ceasing to be enforceable, the occurrence of certain ERISA events, a change of control event and bankruptcy and other insolvency events. If an event of default occurs and is continuing, then holders of a majority in principal amount of the Notes have the right to declare all the Notes then outstanding to be immediately due and payable. In addition, if the Company defaults in payments on any Note, then until such defaults are cured, the holder thereof may declare all the Notes held by it to be immediately due and payable.

ITEM 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
     Management Overview — We are a leading provider of contract services to the North American oil and natural gas industry. Our services primarily involve the drilling, on a contract basis, of land-based oil and natural gas wells and, to a lesser extent, pressure pumping services. In addition to the aforementioned contract services, we also invest, on a working interest basis, in oil and natural gas properties. Prior to the sale of substantially all of the assets of our drilling and completion fluids business in January 2010, we provided drilling fluids, completion fluids and related services to oil and natural gas operators. Due to our exit from the drilling and completion fluids business in January 2010, we have presented the results of that operating segment as discontinued operations in this Report. For the three and nine months ended September 30, 2010 and 2009, our operating revenues from continuing operations consisted of the following (dollars in thousands):
                                                                 
    Three Months Ended September 30,     Nine Months Ended September 30,  
    2010     2009     2010     2009  
Contract drilling
  $ 290,759       77 %   $ 112,294       70 %   $ 741,470       78 %   $ 439,714       77 %
Pressure pumping
    81,104       21       41,687       26       194,219       20       113,408       20  
Oil and natural gas
    6,800       2       5,690       4       21,564       2       15,255       3  
 
                                               
 
  $ 378,663       100 %   $ 159,671       100 %   $ 957,253       100 %   $ 568,377       100 %
 
                                               
     Generally, the profitability of our business is impacted most by two primary factors in our contract drilling segment: our average number of rigs operating and our average revenue per operating day. During the third quarter of 2010, our average number of rigs operating was 178 compared to 73 in the third quarter of 2009. Our average revenue per operating day was $17,730 in the third quarter of 2010 compared to $16,800 in the third quarter of 2009. We had consolidated net income of $29.4 million for the third quarter of 2010 compared to a consolidated net loss of $18.6 million for the third quarter of 2009. The increase in consolidated net

Table of Contents

income was primarily due to our contract drilling segment experiencing an increase in the average number of rigs operating and increases in large fracturing jobs in our pressure pumping segment in the third quarter of 2010 compared to the third quarter of 2009.
     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. Subsequent to reaching a peak in June 2008, there was a significant decline in oil and natural gas prices and a substantial deterioration in the global economic environment. As part of this deterioration, there was substantial uncertainty in the capital markets and access to financing was reduced. Due to these conditions, our customers reduced or curtailed their drilling programs, which 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 2008 to a low of 60 in June 2009 before partially recovering to 184 in September 2010. Furthermore, these factors have resulted in, and could continue to result in, certain of our customers experiencing an inability to pay suppliers, including us. 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 “Risk Factors” included in Part I of our Annual Report on Form 10-K for the fiscal year ended December 31, 2009 and Part II of our Quarterly Report on Form 10-Q for the quarter ended June 30, 2010.
     We believe that our liquidity as of September 30, 2010, which includes approximately $139 million in working capital and approximately $359 million available under our $400 million revolving credit facility, 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 and pay cash dividends.
     On July 2, 2010, we entered into an Asset Purchase Agreement wherein one of our subsidiaries agreed to purchase certain assets and assume certain liabilities from Key Energy Pressure Pumping Services, LLC and Key Electric Wireline Services, LLC relating to the businesses of providing certain pressure pumping services and electric wireline services to participants in the oil and natural gas industry for an approximate aggregate purchase price of $238 million in cash. This transaction closed on October 1, 2010, with two of our subsidiaries purchasing such assets and assuming such liabilities. The purchase price was funded through a combination of cash on hand and a $200 million draw on our revolving credit facility. The revolving credit facility borrowing was subsequently repaid on October 5, 2010 using proceeds from the sale of $300 million in aggregate principal amount of our 4.97% Series A Senior Notes due October 5, 2020.
     If we pursue additional opportunities for growth that require capital, we believe we would be able to satisfy these needs through a combination of working capital, cash generated from operations, borrowing capacity under our revolving credit facility or additional debt or equity financing. However, there can be no assurance that such capital will be available on reasonable terms, if at all.
     Commitments and Contingencies — As of September 30, 2010, we maintained letters of credit in the aggregate amount of $41.2 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 annually at various times during the year and are typically renewed. As of September 30, 2010, no amounts had been drawn under the letters of credit.
     As of September 30, 2010, we had commitments to purchase approximately $250 million of major equipment.
     Trading and Investing — We have not engaged in trading activities that include high-risk securities, such as derivatives and non-exchange traded contracts. We invest cash primarily in highly liquid, short-term investments such as overnight deposits and money market accounts.
     Description of Business — We conduct our contract drilling operations primarily in Texas, New Mexico, Oklahoma, Arkansas, Louisiana, Mississippi, Colorado, Utah, Wyoming, Montana, North Dakota, Pennsylvania, West Virginia and western Canada. As of September 30, 2010, we had approximately 350 marketable land-based drilling rigs. As of October 1, 2010, we provide pressure pumping and wireline services to oil and natural gas operators primarily in Texas and the Appalachian Basin. Pressure pumping services consist primarily of well stimulation and cementing for completion of new wells and remedial work on existing wells. Wireline services consist primarily of perforating, completion and production logging and casing integrity services. Prior to the sale of substantially all of the assets of our drilling and completion fluids business in January 2010, we provided 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. Due to our exit from the drilling and completion fluids business in January 2010, we have presented the results of that operating segment as discontinued operations in this Report.

     The North American land drilling industry has experienced periods of downturn in demand over 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 sustained losses during the downturn periods.
     In addition, exploration and development of unconventional resource plays has substantially increased recently and some drilling rigs are not capable of drilling these wells efficiently. Accordingly, the utilization of some older technology drilling rigs may be hampered by their lack of capability to successfully compete for this work. Other 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:
    movement of drilling rigs from region to region,
 
    reactivation of land-based drilling rigs, or
 
    construction of new drilling rigs.
     Construction of new drilling rigs increased significantly during the last ten years. The addition of new drilling rigs to the market has significantly contributed to excess capacity. We cannot predict either the future level of demand for our contract drilling services or future conditions in the oil and natural gas contract drilling business.
Critical Accounting Policies
     In addition to established accounting policies, our consolidated financial statements are impacted by certain estimates and assumptions made by management. No changes in our critical accounting policies have occurred since the filing of our Annual Report on Form 10-K for the fiscal year ended December 31, 2009.
Liquidity and Capital Resources
     As of September 30, 2010, we had working capital of $139 million, including cash and cash equivalents of $73.9 million compared to working capital of $264 million and cash and cash equivalents of $49.9 million at December 31, 2009. The decrease in working capital during the nine months ended September 30, 2010 was primarily due to capital expenditures and deposits on equipment purchases exceeding operating cash flow.
     During the nine months ended September 30, 2010, our sources of cash flow included:
    $402 million from operating activities,
 
    $100 million in term borrowings under our $500 million credit facility,
 
    $42.6 million in proceeds from the disposal of our drilling and completion fluids business, and
 
    $27.2 million in proceeds from the sale of certain oil and natural gas rights and the disposal of other assets.
     During the nine months ended September 30, 2010, we used $23.1 million to pay dividends on our common stock, $10.3 million to pay debt issuance costs, and $514 million to:
    build new drilling rigs,
 
    make capital expenditures for the betterment and refurbishment of our drilling rigs,
 
    acquire and procure drilling equipment and facilities to support our drilling operations,
 
    fund capital expenditures for our pressure pumping segment, and
 
    fund investments in oil and natural gas properties on a working interest basis.

     On October 27, 2010, our Board of Directors approved a cash dividend on our common stock in the amount of $0.05 per share to be paid on December 30, 2010 to holders of record as of December 15, 2010. 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.
     On August 1, 2007, our Board of Directors approved a stock buyback program, authorizing purchases of up to $250 million of our common stock in open market or privately negotiated transactions. During the nine months ended September 30, 2010, we purchased 8,743 shares of our common stock under the program at a cost of approximately $123,000. As of September 30, 2010, we are authorized to purchase approximately $113 million of our outstanding common stock under the program.
     On August 19, 2010, we entered into the 2010 Credit Agreement. The 2010 Credit Agreement is a committed senior unsecured credit facility that permits aggregate borrowings of up to $500 million pursuant to a revolving credit facility and a term loan facility. The 2010 Credit Agreement replaced a previous unsecured revolving credit facility.
     The revolving credit facility permits aggregate borrowings of up to, at any time outstanding, $400 million, which contains a letter of credit facility that, at any time outstanding, is limited to $150 million and a swing line facility that, at any time outstanding, is limited to $40 million. Subject to customary conditions, we may request that the lenders’ aggregate commitments with respect to the revolving credit facility be increased by up to $100 million, not to exceed total commitments of $500 million. The maturity date for the revolving facility is August 19, 2013.
     The term loan facility provided for a loan of $100 million which was funded on August 19, 2010, the proceeds of which may be used for general corporate purposes. The term loan facility is payable in quarterly principal installments commencing November 19, 2010, and the installment amounts vary from 1.25% of the original principal amount for each of the first four quarterly installments, 2.50% of the original principal amount for each of the subsequent eight quarterly installments, 5.00% of the original principal amount for the next subsequent three quarterly installments and the remainder at maturity. The maturity date for the term loan facility is August 19, 2014.
     Loans under the 2010 Credit Agreement bear interest by reference, at our election, to the LIBOR rate or base rate, provided, that swing line loans bear interest by reference only to the base rate. The applicable margin on LIBOR rate loans varies from 2.75% to 3.75% and the applicable margin on base rate loans varies from 1.75% to 2.75%, in each case determined based upon our debt to capitalization ratio. As of September 30, 2010, the applicable margin on LIBOR rate loans was 2.75% and the applicable margin on base rate loans was 1.75%. A letter of credit fee is payable by us equal to the applicable margin for LIBOR rate loans times the daily amount available to be drawn under outstanding letters of credit. The commitment fee payable to the lenders for the unused portion of the revolving credit facility varies from 0.50% to 0.75% based upon our debt to capitalization ratio and was 0.50% as of September 30, 2010.
     The 2010 Credit Agreement contains customary representations, warranties, indemnities and affirmative and negative covenants. The 2010 Credit Agreement also requires compliance with two financial covenants. We must not permit our debt to capitalization ratio to exceed 45% at any time. The 2010 Credit Agreement generally defines the debt to capitalization ratio as the ratio of (a) total borrowed money indebtedness to (b) the sum of such indebtedness plus consolidated net worth, with consolidated net worth determined as of the last day of the most recently ended fiscal quarter. We also must not permit the interest coverage ratio as of the last day of a fiscal quarter to be less than 3.00 to 1.00. The 2010 Credit Agreement generally defines the interest coverage ratio as the ratio of EBITDA of the four prior fiscal quarters to interest charges for the same period. We were in compliance with these financial covenants as of September 30, 2010. We do not expect that the restrictions and covenants will impair our ability to operate or react to opportunities that might arise.

     As of September 30, 2010, the Company had $100 million outstanding under the term loan facility at an interest rate of 3.125% and no borrowings outstanding under the revolving credit facility. The Company had $41.2 million in letters of credit outstanding at September 30, 2010 and, as a result, had available borrowing capacity of approximately $359 million at that date.
     On October 5, 2010, we completed an issuance and sale of $300 million in aggregate principal amount of our 4.97% Series A Senior Notes due October 5, 2020 (the “Notes”) in a private placement.
     The Notes bear interest at a rate of 4.97% per annum and were priced at 100% of the principal amount of the Notes. We will pay interest on the Notes on April 5 and October 5 of each year commencing on April 5, 2011. The Notes will mature on October 5, 2020. The Notes are prepayable at the our option, in whole or in part, provided that in the case of a partial prepayment, prepayment must be in an amount not less than 5% of the aggregate principal amount of the Notes then outstanding, at any time and from time to time at 100% of the principal amount prepaid, plus accrued and unpaid interest to the prepayment date, plus a “make-whole” premium as specified in the note purchase agreement. We must offer to prepay the Notes upon the occurrence of any change of control. In addition, we must offer to prepay the Notes upon the occurrence of certain asset dispositions if the proceeds therefrom are not timely reinvested in productive assets. If any offer to prepay is accepted, the purchase price of each prepaid Note is 100% of the principal amount thereof, plus accrued and unpaid interest thereon to the prepayment date.
     The note purchase agreement requires compliance with two financial covenants. We must not permit our debt to capitalization ratio to exceed 50% at any time. The note purchase agreement generally defines the debt to capitalization ratio as the ratio of (a) total borrowed money indebtedness to (b) the sum of such indebtedness plus consolidated net worth, with consolidated net worth determined as of the last day of the most recently ended fiscal quarter. We also must not permit the interest coverage ratio as of the last day of a fiscal quarter to be less than 2.50 to 1.00. The note purchase agreement generally defines the interest coverage ratio as the ratio for the four prior quarters of EBITDA to interest charges.
     Events of default under the note purchase agreement include failure to pay principal or interest when due, failure to comply with the financial and operational covenants, a cross default event, a judgment in excess of a threshold event, the guaranty agreement ceasing to be enforceable, the occurrence of certain ERISA events, a change of control event and bankruptcy and other insolvency events. If an event of default occurs and is continuing, then holders of a majority in principal amount of the Notes have the right to declare all the Notes then outstanding to be immediately due and payable. In addition, if we default in payments on any Note, then until such defaults are cured, the holder thereof may declare all the Notes held by it to be immediately due and payable.
     We believe that the current level of cash, short-term investments and borrowing capacity available under our revolving credit facility, together with cash expected to be generated from operations, should be sufficient to fund our current plans to build new equipment, make improvements to our existing equipment and pay cash dividends.
     On July 2, 2010, we entered into an Asset Purchase Agreement wherein one of our subsidiaries agreed to purchase certain assets and assume certain liabilities from Key Energy Pressure Pumping Services, LLC and Key Electric Wireline Services, LLC relating to the business of providing certain pressure pumping services and certain electric wireline services to participants in the oil and natural gas industry for an approximate aggregate purchase price of $238 million in cash. The transaction closed on October 1, 2010, with two of our subsidiaries purchasing such assets and assuming such liabilities. The purchase price was funded through a combination of cash on hand and a $200 million draw on our revolving credit facility. The revolving credit facility borrowing was subsequently repaid on October 5, 2010 using proceeds from the sale of the Notes.
     From time to time, opportunities to expand our business, including acquisitions and the building of new equipment, are evaluated. The timing, size or success of any acquisition and the associated capital commitments are unpredictable. If we pursue additional opportunities for growth that require capital, we believe we would be able to satisfy these needs through a combination of working capital, cash generated from operations, borrowing capacity under our revolving credit facility or additional debt or equity financing. However, there can be no assurance that such capital will be available on reasonable terms, if at all.

     Revenues increased in 2010 compared to 2009 as a result of a significant increase in operating days and an increase in average revenue per operating day. Direct operating costs increased in 2010 compared to 2009 primarily as a result of an increase in the number of operating days. The increase in operating days was due to increased demand largely caused by higher prices for natural gas and oil. Significant capital expenditures were incurred in 2010 and 2009 to build new drilling rigs, to modify and upgrade our drilling rigs and to acquire additional related equipment such as top drives, drill pipe, drill collars, engines, fluid circulating systems, rig hoisting systems and safety enhancement equipment. Depreciation expense increased as a result of capital expenditures.

     Our customers have increased their activities in the development of unconventional reservoirs in the Appalachian Basin resulting in an increase in larger fracturing jobs associated therewith. As a result, we have experienced an increase in the number of larger fracturing jobs as a proportion of the total fracturing jobs we performed. Revenues and direct operating costs increased primarily as a result of the increase in average revenue and direct operating costs per job. Increased average revenue per fracturing job reflects the increase in the proportion of larger fracturing jobs to total fracturing jobs, which was driven by demand for services associated with unconventional reservoirs. Average revenue per other job increased as a result of increased pricing for the services provided and a change in job mix. Average direct operating costs per job increased primarily due to the increase in larger fracturing jobs. Significant capital expenditures have been incurred in recent years to add capacity. Depreciation expense increased as a result of capital expenditures.

     Revenues increased due to higher average sales prices of oil and natural gas and increased oil production partially offset by a reduction in natural gas production. Depreciation, depletion and impairment expense in 2010 includes approximately $119,000 incurred to impair certain oil and natural gas properties compared to approximately $249,000 incurred to impair certain oil and natural gas properties in 2009. Capital expenditures increased in 2010 as a result of greater drilling activity and increased costs per well.

     Selling, general and administrative expense increased in 2010 primarily as a result of increased personnel costs. The provision for bad debts in 2009 resulted from an increase in our reserve on specific account balances based on the deteriorating economic and credit environment at the time. The negative provision for bad debts in 2010 is the result of reductions in our reserve for specific accounts due to improved industry conditions. Gains and losses on the disposal of assets are treated as part of our corporate activities because such transactions relate to corporate strategy decisions of our executive management group. Interest expense increased due to the recognition of deferred financing costs. Interest expense in 2010 includes $3.3 million due to the recognition of remaining deferred financing costs associated with the revolving credit facility that was replaced in August 2010 and includes $1.3 million due to the recognition of deferred financing costs associated with the 364-Day Credit Agreement as it expired on September 30, 2010. Capital expenditures have increased in 2010 due to the ongoing implementation of a new enterprise resource planning system.
     The following tables summarize operations by business segment for the nine months ended September 30, 2010 and 2009:

Capital expenditures
  $ 455,708     $ 308,789       47.6 %
     Revenues increased in 2010 compared to 2009 as a result of a significant increase in operating days somewhat reduced by the impact of a decrease in average revenue per operating day. Average revenue per operating day decreased in 2010 primarily due to decreases in dayrates for rigs that were operating in the spot market and a smaller proportion of rigs on term contracts which are generally at higher rates. Revenues in 2009 also included $8.0 million from the early termination of drilling contracts. We recognized no revenues from the early termination of drilling contracts in 2010. Direct operating costs increased in 2010 compared to 2009

     Our customers have increased their activities in the development of unconventional reservoirs in the Appalachian Basin resulting in an increase in larger fracturing jobs associated therewith. As a result, we have experienced an increase in the number of larger fracturing jobs as a proportion of the total fracturing jobs we performed. A decrease in smaller traditional fracturing jobs contributed to the overall decrease in the number of total fracturing jobs. Revenues and direct operating costs increased primarily as a result of the increase in average revenue and direct operating costs per job. Increased average revenue per fracturing job reflects the increase in the proportion of larger fracturing jobs to total fracturing jobs, which was driven by demand for services associated with unconventional reservoirs. Average revenue per other job increased as a result of increased pricing for the services provided and a change in job mix. Average direct operating costs per job primarily increased due to the increase in larger fracturing jobs. Selling, general and administrative expense increased primarily due to additional costs necessary to support increased business activity in 2010. Significant capital expenditures have been incurred in recent years to add capacity. Depreciation expense increased as a result of capital expenditures.

Average natural gas sales price (per Mcf)
  $ 5.75     $ 4.04       42.3 %
     Revenues increased due to higher average sales prices of oil and natural gas partially offset by a reduction in natural gas production. Average net daily natural gas production decreased primarily due to production declines on existing wells. Depreciation, depletion and impairment expense in 2010 includes approximately $789,000 incurred to impair certain oil and natural gas properties compared to approximately $3.3 million incurred to impair certain oil and natural gas properties in 2009. Depletion expense decreased approximately $378,000 primarily due to lower natural gas production. Capital expenditures increased in 2010 as a result of greater drilling activity and increased costs per well.

     Selling, general and administrative expense increased in 2010 primarily as a result of increased personnel costs. The provision for bad debts in 2009 resulted from an increase in our reserve on specific account balances based on the deteriorating economic and credit environment at the time. The negative provision for bad debts in 2010 is the result of collections of certain accounts that had previously been reserved and reductions in our reserve for certain accounts due to improved industry conditions. Gains and losses on the disposal of assets are treated as part of our corporate activities because such transactions relate to corporate strategy decisions of our executive management group. The gain on asset disposals in 2010 includes a gain of $20.1 million related to the sale of certain rights to explore and develop zones deeper than depths that we generally target for certain of the oil and natural gas properties in which we have working interests. Interest income increased due to the collection of interest on a customer account as well as interest received on prior overpayments of sales taxes in certain jurisdictions. Interest expense increased due to the recognition of deferred financing costs. Interest expense in 2010 includes $3.3 million due to the recognition of remaining deferred financing costs associated with the revolving credit facility that was replaced in August 2010 and includes $1.3 million due to the recognition of deferred financing costs associated with the 364-Day Credit Agreement as it expired on September 30, 2010. Capital expenditures have increased in 2010 due to the ongoing implementation of a new enterprise resource planning system.
Income Taxes
     On January 1, 2010, we converted our Canadian operations from a Canadian branch to a controlled foreign corporation for Federal income tax purposes. Because the statutory tax rates in Canada are lower than those in the United States, this transaction triggered a $5.1 million reduction in our deferred tax liabilities, which is being amortized as a reduction to deferred income tax expense over the weighted average remaining useful life of the Canadian assets.
     As a result of the above conversion, our Canadian assets are no longer subject to United States taxation, provided that the related unremitted earnings are permanently reinvested in Canada. Effective January 1, 2010, we have elected to permanently reinvest these unremitted earnings in Canada, and we intend to do so for the foreseeable future. As a result, no deferred United States Federal or state income taxes have been provided on such unremitted foreign earnings, which totaled approximately $1.7 million as of September 30, 2010.
Recently Issued Accounting Standards
     In June 2009, the FASB issued a new accounting standard that amends the accounting and disclosure requirements for the consolidation of variable interest entities. This new standard removes the previously existing exception from applying consolidation guidance to qualifying special-purpose entities and requires ongoing reassessments of whether an enterprise is the primary beneficiary of a variable interest entity. Before this new standard, generally accepted accounting principles required reconsideration of whether an enterprise is the primary beneficiary of a variable interest entity only when specific events occurred. This new standard is effective as of the beginning of each reporting entity’s first annual reporting period that begins after November 15, 2009, for interim periods within that first annual reporting period, and for interim and annual reporting periods thereafter. This new standard became effective for us on January 1, 2010. The adoption of this standard did not impact our consolidated financial statements.
     In October 2009, the FASB issued a new accounting standard that addresses the accounting for multiple-deliverable revenue arrangements to enable vendors to account for deliverables separately rather than as a combined unit. This new standard addresses how to separate deliverables and how to measure and allocate arrangement consideration to one or more units of accounting. Existing accounting standards require a vendor to use objective and reliable evidence of fair value for the undelivered items or the residual method to separate deliverables in a multiple-deliverable arrangement. Under the new standard, it is expected that multiple-deliverable arrangements will be separated in more circumstances than under current requirements. The new standard establishes a hierarchy for determining the selling price of a deliverable for purposes of allocating revenue to multiple deliverables. The selling

Table of Contents

price used will be based on vendor-specific objective evidence if available, third-party evidence if vendor-specific objective evidence is not available, or estimated selling price if neither vendor-specific objective evidence nor third-party evidence is available. The new standard must be prospectively applied to all revenue arrangements entered into in fiscal years beginning on or after June 15, 2010 and will be effective for the Company on January 1, 2011. The adoption of this standard is not expected to have a material impact on our consolidated financial position, results of operations or cash flows.
Volatility of Oil and Natural Gas Prices and its Impact on Operations and Financial Condition
     Our revenue, profitability, financial condition and rate of growth are substantially dependent upon prevailing prices for natural gas and 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 (monthly average Henry Hub price as reported by the Energy Information Administration) peaked in June at $13.06 per Mcf before rapidly declining to an average of $5.99 per Mcf in December. In 2009, the monthly average market price of natural gas declined further to a low of $3.06 per Mcf in September. This decline in the market price of natural gas resulted in our customers significantly reducing their drilling activities beginning in the fourth quarter of 2008 and drilling activities remained low throughout 2009. Construction of new land drilling rigs in the United States during the last ten years has significantly contributed to excess capacity. As a result of these factors, our average number of rigs operating has declined significantly from historic highs. 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. Low market prices for natural gas and oil would likely result in demand for our drilling rigs decreasing and would adversely affect our operating results, financial condition and cash flows.
     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.
ITEM 3. Quantitative and Qualitative Disclosures About Market Risk
     We currently have exposure to interest rate market risk associated with any borrowings that we have under our term credit facility or our revolving credit facility. Interest is paid on the outstanding principal amount of borrowings at a floating rate based on, at our election, LIBOR or a base rate. The margin on LIBOR loans ranges from 2.75% to 3.75% and the margin on base rate loans ranges from 1.75% to 2.75%, based on our debt to capitalization ratio. At September 30, 2010, the margin on LIBOR loans was 2.75% and the margin on base rate loans was 1.75%. As of September 30, 2010, we had no borrowings outstanding under our revolving credit facility and $100 million outstanding under our term credit facility at an interest rate of 3.125%.
     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 risk is not material to our results of operations or financial condition.
     The carrying values of cash and cash equivalents, trade receivables and accounts payable approximate fair value due to the short-term maturity of these items.
ITEM 4. Controls and Procedures
     Disclosure Controls and Procedures — We maintain disclosure controls and procedures (as such terms are defined in Rules 13a-15(e) and 15d-15(e) promulgated under the Exchange Act), designed to ensure that the information required to be disclosed in the reports that we file with the SEC under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), as appropriate, to allow timely decisions regarding required disclosure.
     Under the supervision and with the participation of our management, including our CEO and CFO, we conducted an evaluation of the effectiveness of our disclosure controls and procedures as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on that evaluation, our CEO and CFO concluded that our disclosure controls and procedures were effective as of September 30, 2010.
