PROXY STATEMENT
 
 
ANNUAL MEETING OF STOCKHOLDERS
To Be Held June 8, 2011
 
GENERAL INFORMATION ABOUT THE ANNUAL MEETING AND VOTING
 
The Board of Directors (the “Board” or “Board of Directors”) of Patterson-UTI Energy, Inc., a Delaware corporation (“Patterson-UTI”), has made these proxy materials available to you on the Internet, or, upon your request has delivered printed versions of these materials to you by mail beginning on or about April 26, 2011. Patterson-UTI is furnishing this proxy statement in connection with the solicitation by the Board of Directors of proxies to be voted at the 2011 annual meeting of stockholders of Patterson-UTI (the “Meeting”). The Meeting will be held Wednesday, June 8, 2011, at 10:00 a.m., local time, at the Hilton Houston North Hotel, 12400 Greenspoint Drive, Houston, Texas 77060, or at any adjournment thereof. The Notice of Internet Availability of Proxy Materials (the “Notice”) was mailed to each of Patterson-UTI’s stockholders (other than those who previously requested electronic delivery) entitled to vote at the Meeting on or about April 26, 2011.
 
Pursuant to the “notice and access” rules adopted by the Securities and Exchange Commission (the “SEC”), Patterson-UTI has elected to provide stockholders access to its proxy materials over the Internet. Accordingly, Patterson-UTI sent a Notice to all of its stockholders as of the record date. The Notice includes instructions on how to access Patterson-UTI’s proxy materials over the Internet and how to request a printed copy of these materials. In addition, by following the instructions in the Notice, stockholders may request to receive proxy materials in printed form by mail or electronically by email on an ongoing basis.
 
Choosing to receive your future proxy materials by email will save us the cost of printing and mailing documents to you and will help conserve natural resources. If you choose to receive future proxy materials by email, you will receive an email next year with instructions containing a link to those materials and a link to the proxy voting site. Your election to receive proxy materials by email will remain in effect until you terminate it.
 
If your shares are registered directly in your name with our transfer agent, Continental Stock Transfer & Trust Company, you are considered the “stockholder of record” with respect to those shares, and the Notice was sent directly to you.
 
If your shares are held in an account at a brokerage firm, bank, broker-dealer, or other similar organization, then you are the beneficial owner of shares held in “street name,” and the Notice was forwarded to you by that organization. As a beneficial owner, you have the right to direct that organization on how to vote the shares held in your account.
 
Whether you are a “stockholder of record” or hold your shares in “street name,” you may direct your vote without attending the Meeting in person.
 
If you are a stockholder of record, you may vote by Internet or by telephone by following the instructions on the Notice. If you request printed copies of the proxy materials by mail, you may also vote by signing and submitting your proxy card and returning it by mail. You should sign your name exactly as it appears on the proxy card. If you are signing in a representative capacity (for example, as guardian, executor, trustee, custodian, attorney or officer of a corporation), you should indicate your name and title or capacity.
 
If you are the beneficial owner of shares held in street name, you may be eligible to vote your shares electronically over the Internet or by telephone by following the instructions on the Notice. If you request printed


Table of Contents

copies of the proxy materials by mail, you may also vote by signing the voter instruction card provided by your brokerage firm, bank, broker-dealer, or other similar organization and returning it by mail. If you provide specific voting instructions by mail, telephone or the Internet, your shares will be voted by your brokerage firm, bank, broker-dealer, or similar organization as you have directed.
 
Properly submitted proxies received either by mail, Internet, telephone or in person, in time to be counted for the Meeting will be voted as you have directed in your proxy, unless you revoke your proxy in the manner provided below. As to any matter for which you give no direction in your proxy, your shares will be voted as follows:
 
  •  “FOR” the election of all of the nominees to the Board of Directors;
 
  •  “FOR” the approval of the material terms of the performance goals that may apply to performance-based awards under Patterson-UTI’s Long Term Incentive Plan;
 
  •  “FOR” the approval, on an advisory basis, of our executive compensation;
 
  •  “FOR” the approval of an advisory vote to be held every year on executive compensation;
 
  •  “FOR” the ratification of PricewaterhouseCoopers LLP as the independent registered public accounting firm of Patterson-UTI for the fiscal year ending December 31, 2011; and
 
  •  “FOR” or “AGAINST” any other proposals that may be properly submitted at the Meeting at the discretion of the persons named in the proxy.
 
If you are a stockholder of record, you may revoke your proxy before the proxy is voted by either:
 
  •  submitting a new proxy with a later date, including a proxy submitted by the Internet or by telephone, in time to be counted for the meeting;
 
  •  notifying the Secretary of Patterson-UTI in writing before the Meeting that you have revoked your proxy; or
 
  •  attending the Meeting and voting in person.
 
If your shares are held in street name, you must obtain a proxy executed in your favor from the stockholder of record (that is, your brokerage firm, bank, broker-dealer or similar organization) to be able to vote at the Meeting.
 
The Board of Directors is making this solicitation. Patterson-UTI’s officers and other employees, without compensation other than regular compensation, may solicit proxies by mail, email, the Internet, telephone, electronic means and personal interview. Patterson-UTI does not intend to retain a proxy solicitation firm to assist in the solicitation of proxies of stockholders, but may do so if circumstances warrant. Patterson-UTI will pay all costs associated with this solicitation.
 
SHARES OUTSTANDING AND VOTING RIGHTS
 
Only stockholders of record of Patterson-UTI’s common stock, $.01 par value per share (the “Common Stock”), at the close of business on April 11, 2011 are entitled to notice of and to vote at the Meeting or any adjournment or postponement thereof. At the close of business on April 11, 2011, there were 154,246,395 shares of Common Stock issued and outstanding. Holders of record of Common Stock on April 11, 2011 will be entitled to one vote per share on all matters to properly come before the Meeting. A list of stockholders entitled to notice of and to vote at the Meeting will be made available during regular business hours at the offices of Patterson-UTI Energy, Inc., 450 Gears Road, Suite 500, Houston, Texas 77067, from May 24, 2011 through June 7, 2011 and at the Meeting for examination by any stockholder for any purpose germane to the Meeting.
 
A quorum is necessary to transact business at the Meeting. A majority of the shares of Common Stock outstanding on April 11, 2011 will constitute a quorum. The shares held by each stockholder who attends the Meeting in person, signs and timely returns the form of proxy or properly votes using the Internet or telephone will be counted for purposes of determining the presence of a quorum at the Meeting.
 
“Broker non-votes” will be considered present at the Meeting but will not be counted to determine the total number of votes cast. Broker non-votes occur when nominees, such as brokerage firms, banks, broker-dealers, or


2


Table of Contents

other similar organizations holding shares on behalf of the beneficial owners, are prohibited from exercising discretionary voting authority for beneficial owners who have not provided voting instructions. If you do not give instructions to your bank, brokerage firm or other agent, the bank, brokerage firm or other agent will nevertheless be entitled to vote your shares of Common Stock in its discretion on “routine matters” and may give or authorize the giving of a proxy to vote the shares of Common Stock in its discretion on such matters. The ratification of an independent registered public accounting firm is generally considered a routine matter, whereas the election of directors, action with respect to incentive plans and the advisory votes on executive compensation and the frequency of such future advisory votes are not considered routine matters. For these reasons, please promptly vote in accordance with the instructions provided by your brokerage firm, bank, broker-dealer, or other similar organization.
 
PROPOSAL NO. 1
 
ELECTION OF DIRECTORS
 
Patterson-UTI’s bylaws provide that the number of members of the Board of Directors shall be fixed either by amendment to the bylaws or by resolution of the Board of Directors. Directors are elected to serve until the next annual meeting of stockholders and until their successors are elected and qualified. Patterson-UTI’s bylaws provide that the affirmative vote of a plurality of the votes cast at the meeting at which a quorum is present is required for the election of directors. Shares as to which a stockholder withholds authority to vote on the election of directors and shares as to which a broker indicates that it does not have discretionary authority to vote on the election of directors will not be counted as voting thereon and will not affect the election of the nominees receiving a plurality of the votes cast.
 
The enclosed form of proxy provides a means for you to either:
 
  •  vote “FOR” the election of the nominees to the Board of Directors listed below,
 
  •  withhold authority to vote for one or more of the nominees, or
 
  •  withhold authority to vote for all of the nominees.
 
The Board of Directors recommends that you vote “FOR” all of the nominees.  Unless you give contrary instructions in your proxy, your proxy will be voted “FOR” the election of all of the nominees to the Board of Directors. If any nominee should become unable or unwilling to accept nomination or election, the person acting under the proxy will vote for the election of such other person as the Board of Directors may recommend. The Board has no reason, however, to believe that any of the nominees will be unable or unwilling to serve if elected. Abstentions will have no effect with respect to the election of directors. A broker non-vote will be counted for purposes of establishing a quorum, but will not be treated as a vote cast with respect to the election of directors. This will have the effect of reducing the absolute number of votes cast for the election of directors.
 
There are no arrangements or understandings between any person and any of the directors pursuant to which such director was selected as a nominee for election at the Meeting. There are no family relationships among any of the directors or executive officers of Patterson-UTI.
 
Our corporate governance guidelines require that if a director receives in an uncontested election a greater number of “withhold” votes than votes cast “for” his or her election, the Nominating and Corporate Governance Committee of the Board of Directors will undertake a prompt evaluation of the appropriateness of the director’s continued service on the Board of Directors. In performing this evaluation, the Nominating and Corporate Governance Committee will review all factors it deems relevant, including the stated reasons why votes were withheld, the director’s length of service, his or her past contributions to Patterson-UTI and the availability of other qualified candidates. The Nominating and Corporate Governance Committee will then make its recommendation to the Board. The Board of Directors will review the Nominating and Corporate Governance Committee’s recommendation and consider such further factors and information as it deems relevant. The Board of Directors will act on the Nominating and Corporate Governance Committee’s recommendation no later than 90 days following the date of the stockholders’ meeting. If the Board of Directors determines remedial action is appropriate, the director shall promptly take whatever action is requested by the Board. If the director does not promptly take the recommended

Table of Contents

remedial action or if the Board of Directors determines that immediate resignation is in the best interests of Patterson-UTI and its stockholders, the Board of Directors may accept the director’s resignation that will have been tendered as follows. Each director will as a condition to his or her appointment or election as a director or nomination as a director agree in writing to comply with the terms of Patterson-UTI’s majority voting policy and provide to the Board of Directors an irrevocable resignation that will be effective upon (i) the failure to receive the required vote at the next annual meeting at which such director faces re-election and (ii) the Board of Directors’ acceptance of such resignation.
 
Set forth below is the name, age, position and a brief description of the business experience during at least the past five years of each of the members of Patterson-UTI’s Board of Directors, as well as specific qualifications, attributes and skills of such member that were identified by the Nominating and Corporate Governance Committee when concluding such member should be nominated to serve on the Board of Directors. Each current member of Patterson-UTI’s Board of Directors is a nominee for election to the Board of Directors.

When considering whether directors and nominees have the experience, qualifications, attributes and skills, taken as a whole, to enable the Board of Directors to satisfy its oversight responsibilities effectively in light of Patterson-UTI’s business and structure, the Nominating and Corporate Governance Committee and the Board of Directors focused primarily on the information discussed in each of the directors’ individual biographies set forth below.
 
In particular, with regard to Mr. Buckner, the Board of Directors considered his past and current service as a director of oil and gas companies, as well as his experience, expertise and background with regard to accounting matters, which includes his role as the former chairman of Ernst & Young LLP’s United States energy practice.
 
With regard to Mr. Huff, the Board of Directors considered his background as an executive of publicly traded oilfield services companies and as an owner and manager of a private equity firm and investment firm focused on the oilfield service industry. The Board noted his knowledge and experience in a broad range of oilfield products and services and his current and historical experience in managing operations in both the United States and internationally. The Board also considered Mr. Huff’s expertise and background with regard to accounting and legal matters, which, among other things, provides guidance to Patterson-UTI in assessing its corporate governance structure, policies and procedures.
 
With regard to Mr. Hunt, the Board of Directors considered that his over twenty-five years of experience covering most phases of the upstream oil and natural gas industry in the United States and Canada, including the evaluation of exploration and development programs, oil and natural gas production and pipeline operations, and project development and major production facility construction provides Patterson-UTI with an invaluable perspective of the oil and natural gas industry and its customers. In addition, Mr. Hunt’s many years of senior executive experience leading natural gas distribution, storage and marketing companies provides insight into the management of multi-faceted businesses and the markets for natural gas in North America.
 
With regard to Mr. Peak, the Board of Directors considered his nearly forty years in the energy industry, including in a financial capacity, as well as his current role as the chairman and chief executive officer of a publicly traded oil and gas exploration and production company. This experience and background provides Patterson-UTI with an important perspective into its customers, current industry conditions and expectations of where the oil and natural gas market is headed.

With regard to Mr. Talbott, the Board of Directors considered his more than fifty years of experience in the oil and gas industry, more than thirty of which has been with Patterson-UTI, which provides unique and valuable knowledge of the U.S. land drilling industry and a historical perspective of the cyclical nature of the oil and natural gas industry.
 
With regard to Mr. Berns, the Board of Directors considered his more than twenty-five years of financial, mergers and acquisitions and transactional experience, including over fifteen years in the oil and gas industry. This experience and background, provides perspective on the cyclical nature of the oil and gas industry and allows Mr. Berns to provide valuable direction with respect to Patterson-UTI’s financial affairs, corporate transactions and strategic decisions.
 
With regard to Mr. Siegel, the Board of Directors considered his broad business and legal experience, as well as his expertise with respect to Patterson-UTI’s business. In addition, the Board considered Mr. Siegel’s demonstrated leadership for more than 15 years of both Patterson-UTI and one of its predecessor companies, UTI Energy Corp. In addition, the Board considered Mr. Siegel’s prior leadership experience in other public companies and in the oil services industry, and in numerous other businesses and industries. Mr. Siegel also brings substantial experience and expertise in mergers and acquisitions, capital structure transactions, strategic planning, and board and business management. Mr. Siegel’s broad and deep experience and expertise allows him to provide Patterson-UTI with valuable leadership in all areas of its business endeavors.

Board Leadership Structure, Lead Director and Board Role in Risk Oversight
 
The Board evaluates its leadership structure and role in risk oversight on an ongoing basis. The decision on whether to combine or separate the Chairman and Chief Executive Officer (“CEO”) role is determined on the basis of what the Board considers to be best for Patterson-UTI at any given point in time. Patterson-UTI’s current Board leadership structure separates the role of Chairman and CEO.
 
The Board also believes part of an effective Board leadership structure is to have a lead independent director, the “Lead Director.” The Board has appointed Mr. Huff as the Lead Director. The independent directors meet regularly in executive sessions at which only independent directors are present, and the Lead Director chairs those sessions. The Lead Director serves as a liaison between the Chairman and the independent directors, consults with regard to Board and agenda items, and works with the chairpersons of Board committees as appropriate.
 
The Nominating and Corporate Governance Committee and the Board currently believe that the Board’s leadership structure, which includes the separation of the role of CEO and Chairman and the appointment of an independent Lead Director, is appropriate because it, among other things, provides for sufficient independence between the Board and management and for an independent director who provides board member leadership.
 
The Board has adopted Corporate Governance Guidelines, which can be accessed electronically in the “Governance” section of Patterson-UTI’s website at www.patenergy.com. The Guidelines describe one of the Board’s primary responsibilities as overseeing Patterson-UTI’s processes for assessing and managing risks. The Board discharges this responsibility, in part, through regular inquiries from the Chairman of the Board and/or the Lead Director to management, periodic communications from management to the Board of Directors of particular risks and events, and discussions during Board meetings with and without management of general and specific risks to Patterson-UTI.

Meetings and Committees of the Board of Directors
 
The Board of Directors met nine times during the year ended December 31, 2010. Each director attended, in person or by telephone, at least 75% of the aggregate of all meetings held by the Board and meetings of each committee on which such director served. A majority of the members of the Board of Directors are independent within the meaning of the Nasdaq Stock Market, Inc. (“Nasdaq”) listing standards. Specifically, the Board has determined that Messrs. Buckner, Huff, Hunt and Peak are independent within the meaning of the Nasdaq listing standards. In reaching this conclusion, the Board considered that Mr. Huff controls and manages two investment companies, which have interests in oilfield service portfolio companies that, prior to 2010, have supplied parts and equipment to Patterson-UTI in the ordinary course of their businesses consistent with customary terms in the industry. In reaching this conclusion, the Board also considered that Mr. Peak is the Chairman and Chief Executive Officer of a publicly traded independent natural gas and oil company, which has a subsidiary that obtained contract drilling services from Patterson-UTI in the ordinary course of their businesses consistent with customary terms in the industry. The Board has determined that these transactions are not material to such companies, Patterson-UTI or Messrs. Huff or Peak and that such transactions do not affect either director’s independence under applicable rules and regulations.
 
The Board of Directors has established four standing committees, an Executive Committee, an Audit Committee, a Compensation Committee and a Nominating and Corporate Governance Committee.
 
The Executive Committee, which currently is composed of Messrs. Siegel, Talbott and Berns, has the authority, to the extent permitted by applicable law, to act for the Board in all matters arising between regular or special meetings of the Board of Directors.

All of the director nominees are existing directors of Patterson-UTI standing for re-election to the Board of Directors.
 
On behalf of the Board, the Nominating and Governance Committee considers director nominees recommended by Patterson-UTI’s stockholders if the recommendations are made in accordance with all legal requirements, including applicable provisions of Patterson-UTI’s restated certificate of incorporation and bylaws. In accordance with Patterson-UTI’s bylaws, in addition to any other applicable requirements, nominations of persons for election to the Board may be made at a meeting of stockholders only by or at the direction of the Board or by a stockholder who is a stockholder of record on the date of the giving of the notice provided for below and on the record date for the determination of stockholders entitled to vote at such annual meeting and gives timely notice of such nomination in writing to the Secretary of Patterson-UTI. To be timely with respect to the 2012 annual meeting of stockholders, a stockholder’s notice must be delivered to or mailed and received at Patterson-UTI’s principal executive offices not earlier than February 9, 2012 and not later than March 10, 2012; provided, however, that in the event that the annual meeting is called for a date that is not within 30 days before or after June 8, 2012, notice by the stockholder must be received not later than the close of business on the tenth day following the day on which such notice of the date of the meeting was mailed or public disclosure of the annual meeting date was made, whichever occurs first.
 
A stockholder’s notice to the Secretary of Patterson-UTI shall set forth:
 
  •  as to each person whom the stockholder proposes to nominate for election or re-election as director, all information relating to such person that is required to be disclosed in solicitations of proxies for election of directors, or is otherwise required, in each case pursuant to Regulation 14A promulgated under the Exchange Act, or any successor regulation thereto,
 
  •  the name and record address of the stockholder proposing such nomination,
 
  •  the class and number of shares of Patterson-UTI that are beneficially owned by the stockholder,
 
  •  a description of all arrangements or understandings between such stockholder and each proposed nominee and any other person or persons (including their names) pursuant to which the nomination or nominations are to be made by such stockholder, and
 
  •  a representation that such stockholder intends to appear in person or by proxy at the meeting to nominate the persons named in the notice.
 
Such notice must be accompanied by a written consent of each proposed nominee to being named as a nominee and to serve as a director if elected.
 
The Nominating and Corporate Governance Committee determines qualification criteria and procedures for the identification and recruitment of candidates for election to serve as directors of Patterson-UTI. The Nominating and Corporate Governance Committee relies on the knowledge and relationships of Patterson-UTI and its officers and directors, as well as third parties when it deems appropriate, to identify and evaluate nominees for director, including nominees recommended by stockholders. In evaluating a nominee for director, the Nominating and Corporate Governance Committee considers the nominee’s skills, expertise, industry and other knowledge, personal and professional ethics, integrity and values, sound business judgment and willingness to commit sufficient time to the Board and be committed to representing the long-term interests of Patterson-UTI’s stockholders. Although the Nominating and Corporate Governance Committee does not have a stand-alone policy with regard to consideration of diversity in identifying director nominees, it considers diversity in professional background, experience, expertise (including as to financial matters) and perspective (including as to age, gender and ethnicity) with respect to the Board of Directors composition as a whole when evaluating a director nominee.
 
Succession Planning
 
The Board of Directors oversees processes and procedures to provide continuity of well-qualified executive leadership and to assess whether such leadership possesses the skill and talent to execute Patterson-UTI’s long term business strategies. The Board of Directors reviews the succession plan for the Chief Executive Officer and the senior executives tailored to reflect the Board’s standards for executive leadership and Patterson-UTI’s business

PROPOSAL NO. 2
 
APPROVAL OF MATERIAL TERMS OF THE PERFORMANCE CRITERIA
UNDER THE LONG-TERM INCENTIVE PLAN
 
Patterson-UTI’s Board of Directors is seeking stockholder approval of the material terms of the performance goals that may apply to performance-based awards under the Patterson-UTI Energy, Inc. 2005 Long-Term Incentive Plan (the “LTIP”). This approval is necessary to preserve Patterson-UTI’s federal income tax deduction for performance-based compensation paid to certain executive officers under Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”).
 
The Compensation Committee places a strong emphasis on performance-based compensation, which promotes stockholder value by linking the employee’s reward to the achievement of Patterson-UTI’s business strategies and goals. The purposes of the LTIP are to motivate key employees to improve stockholder value by linking a portion of their cash compensation to Patterson-UTI’s financial performance, reward key employees for improving Patterson-UTI’s financial performance and help attract and retain key employees. The Board of Directors believes it would be in the best interests of the stockholders and Patterson-UTI to approve the material terms of the performance criteria under the LTIP.
 
Certain material features of the LTIP are discussed below; however, the description is subject to, and qualified by the full text of the LTIP, attached as Appendix A.

Table of Contents

Background
 
Section 162(m) of the Code imposes an annual deduction limit of $1 million on the amount of compensation paid to each of the Chief Executive Officer and the other three highest compensated officers of Patterson-UTI (other than the CFO) as determined on the last day of a tax year. The deduction limit does not apply to performance-based compensation that satisfies the requirements of Section 162(m) of the Code. The requirements of Section 162(m) of the Code for performance-based compensation include shareholder approval of the material terms of the performance goals under which the compensation is paid. The material terms include (1) the employees eligible to receive compensation upon attainment of a goal, (2) the business criteria on which the goals may be based, and (3) the maximum amount payable to an employee upon attainment of a goal.
 
Compensation paid under the LTIP, under appropriate circumstances, is intended to meet the “performance-based compensation” exception under Section 162(m) of the Code, so that Patterson-UTI will be permitted to receive a federal income tax deduction for the payment of this incentive compensation. Performance-based awards under the LTIP may be granted to key employees of Patterson-UTI and its subsidiaries and affiliates, and to non-employee directors of Patterson-UTI.
 
The LTIP was approved by Patterson-UTI stockholders in 2005 and subsequently approved by stockholders and Patterson-UTI’s Board of Directors with respect to subsequent amendments. All references to the LTIP in this discussion include a reference to the LTIP amendments.
 
Performance Criteria
 
If the Compensation Committee determines that Section 162(m) of the Code (see “Federal Income Tax Consequences — Performance-Based Compensation” below) applies (or is likely to apply) to a restricted stock award, performance award or other stock unit award, the lapsing of restrictions on the award and the distribution of cash, shares or other property pursuant to such award, shall be subject to the achievement of one or more objective performance goals established by the Compensation Committee, which shall be based on attaining specified levels in one or more areas, such as: net sales; revenue growth; pre-tax income before allocation of corporate overhead and bonus; earnings per share; operating income or net income; return on stockholders’ equity; attainment of strategic and operational initiatives; appreciation in and/or maintenance of the price of the Common Stock or other publicly-traded securities of Patterson-UTI; market share; gross profits; earnings before taxes or before interest and taxes or before interest, taxes, depreciation, depletion and amortization; comparisons with various stock market indices; improvement in or attainment of expense levels or working capital levels; cash margins; safety records; and rig utilization and rig count growth. Performance goals may be measured solely by reference to Patterson-UTI’s performance or the performance of a subsidiary, division, business segment or business unit of Patterson-UTI, or based upon the relative performance of other companies or upon comparisons of any of the indicators of performance relative to other companies, in each case as specified by the Compensation Committee in the award. The Compensation Committee also may adjust performance goals to reflect the impact of specified events, occurrences or transactions, accounting or tax law changes or other extraordinary or nonrecurring events.
 
Administration
 
The LTIP is administered by the Compensation Committee of Patterson-UTI’s Board of Directors, which comprises exclusively non-employee independent directors. The LTIP provides for the granting of incentive stock options (“ISOs”) that are intended to meet the provisions of Section 422 of the Code, and non-incentive stock options (“NQSOs”), as well as other awards, such as tandem and freestanding SARs, restricted stock awards, other stock unit awards, performance shares, performance units and dividend equivalents. Certain awards under the LTIP may be paid in cash or Common Stock, as determined by the Compensation Committee. The Compensation Committee has the exclusive authority to select the participants to whom awards may be granted under the LTIP, and to determine the type, size and terms of each such award. The Compensation Committee also makes all determinations that it decides are necessary or desirable in the interpretation and administration of the LTIP. In addition, the Compensation Committee may, if consistent with applicable rules, regulations and Nasdaq requirements, delegate to a committee of one or more directors or to one or more executive officers the right to grant, cancel and suspend awards to employees who are not directors or executive officers of Patterson-UTI.

General Terms
 
The following describes general terms of the LTIP:
 
  •  The aggregate number of shares of Common Stock authorized for grant under the LTIP is 15,250,000, reduced by the number of shares that are subject to awards granted under equity plans of Patterson-UTI existing during the period commencing on January 1, 2005 and ending on the date the LTIP was approved by the Patterson-UTI stockholders. Shares that are subject to options or SARs count as one (1.0) share of Common Stock against the aggregate number. Shares that are subject to other awards that were awarded prior to June 5, 2008 count as one and six tenths (1.6) shares of Common Stock against the aggregate number, shares that are subject to other awards that were awarded on or after June 5, 2008 but prior to April 26, 2010 count as two (2.0) shares of Common Stock against the aggregate number and shares that are subject to other awards that were awarded on or after April 26, 2010 count as one and thirty-five hundredths (1.35) shares of Common Stock against the aggregate number.
 
  •  Generally, if an award granted under the LTIP or the other existing equity plans of Patterson-UTI expires, is forfeited, is settled in cash or otherwise terminates without the issuance of all or a portion of the shares of Common Stock subject to the award, the shares allocable to the expired, forfeited, cash settled, or terminated portion of the award will be available for awards again under the LTIP. Any shares of Common Stock that again become available for grant under the LTIP will be added back as one (1.0) share if the shares were subject to options or SARs, and one and six tenths (1.6) shares if the shares were subject to awards other than options or SARs that were forfeited, expire or otherwise terminated prior to June 5, 2008 or two (2.0) shares if the shares were subject to awards other than options or SARs that are forfeited, expire or otherwise terminate on or after June 5, 2008 but prior to April 26, 2010 or one and thirty-five hundredths (1.35) shares if the shares were subject to awards other than options or SARs that are forfeited, expire or otherwise terminate on or after April 26, 2010.
 
  •  Directors, employees, including officers, consultants and advisors are eligible for awards. As of December 31, 2010 Patterson-UTI had four non-employee directors and approximately 7,000 full time employees.
 
  •  The LTIP provides for awards of NQSOs, ISO, tandem and freestanding SARs, restricted stock awards, other stock unit awards, performance awards and dividend equivalents.
 
  •  The Board of Directors, at any time, may amend the terms of the LTIP, subject to the stockholder approval requirements of Nasdaq and other rules and regulations applicable to Patterson-UTI.
 
  •  Under the LTIP, no participant may be granted (i) options or SARs during any 12-month period with respect to more than 1,000,000 shares of Common Stock or (ii) restricted stock, performance awards and/or other stock unit awards that are denominated in shares in any 12-month period with respect to more than 500,000 shares. In addition to the foregoing limits, the maximum dollar value payable to any participant in any 12-month period with respect to performance awards is $5,000,000.
 
Options
 
  •  The vesting schedule for options is set by the Compensation Committee; however, options may not fully vest sooner than one year from the date of grant, except for certain limited exceptions.
 
  •  The term of options is set by the Compensation Committee, but may not exceed 10 years.
 
  •  The exercise price for options may be paid in cash, with previously acquired shares of Common Stock, or by other means approved by the Compensation Committee.
 
  •  Each option granted under the LTIP is granted with an exercise price equal to or greater than the fair market value of the Common Stock at the time such option is granted. Repricing is not permitted with respect to options.
 
SARs
 
  •  SARs may be granted alone or in connection with the grant of any option or other award.


11


Table of Contents

 
  •  Each SAR granted under the LTIP is granted with a grant price equal to or greater than the fair market value of the Common Stock at the time such SAR is granted. Repricing is not permitted with respect to SARs.
 
  •  SARs granted alone may be exercised at such times and be subject to such terms and conditions as the Compensation Committee may impose. SARs that are granted in tandem with options may be exercised only on the surrender of the right to purchase an equivalent number of shares under the related options and may be exercised only with respect to the shares of Common Stock for which the related options are then exercisable.
 
  •  The term of SARs may not exceed 10 years.
 
  •  A SAR entitles a participant to surrender any then exercisable portion of the SAR and, if applicable, the related option, in exchange for an amount equal to the excess of (1) the fair market value of a share of Common Stock on the date of exercise over (2) the grant price of the SAR on the date that the SAR was granted, or, if the SAR is related to an option, as specified by the Compensation Committee in its sole discretion, subject to certain limitations.
 
  •  Upon the exercise of a SAR, payment shall be made in whole shares of Common Stock.
 
Restricted Stock Awards
 
  •  The Compensation Committee determines the material terms of the restricted stock awards, including the price, if any, to be paid by the recipient, and the vesting schedule and conditions, which may include the attainment of specified performance objectives described below.
 
  •  A restricted stock award that is subject solely to continued employment restrictions of employees of Patterson-UTI may not fully vest sooner than three years from the date of grant, except for certain limited exceptions.
 
  •  Beginning on the date of grant, a participant receiving a restricted stock award will become a stockholder of Patterson-UTI with respect to all shares of Common Stock subject to the restricted stock award, which, unless the Compensation Committee determines otherwise at the time of the grant, includes the right to vote such shares and receive regular, ordinary dividends in respect of such shares.
 
Other Stock Units
 
  •  The Compensation Committee may grant other stock unit awards under the LTIP, which have a value equal to an identical number of shares of Common Stock. Other stock unit awards may also be a form of payment for other awards granted under the LTIP and other earned cash-based incentive compensation.
 
  •  The payment of other stock units may be in cash, shares of Common Stock, other property, or any combination of the foregoing, and may be made in a lump sum or, in accordance with procedures established by the Compensation Committee, on a deferred basis subject to the requirements of Section 409A of the Code.
 
  •  Other stock unit awards that are subject solely to continued employment restrictions of employees of Patterson-UTI may not fully vest sooner than three years from the date of grant, except for certain limited exceptions.
 
Dividend Equivalent Rights
 
  •  The Compensation Committee may grant dividend equivalent rights either in connection with awards or as separate awards under the LTIP. Amounts payable in respect of dividend equivalent rights may be payable currently or, if applicable, deferred until the lapsing of restrictions on the dividend equivalent rights or until the vesting, exercise, payment, settlement or other lapse of restrictions on the award to which the dividend equivalent rights relate. If dividend equivalents are granted in connection with performance unit or performance share awards, no dividend equivalents will be payable until the Compensation Committee


12


Table of Contents

  determines that the performance conditions relating to the settlement of the performance unit or performance share award have been satisfied.
 
  •  No SARs have been granted under the LTIP and no option granted under the LTIP has included dividend equivalent rights.
 
Performance Awards
 
  •  Performance awards are payable in cash, shares of Common Stock, other property, or a combination of the foregoing, and may be paid in a lump sum, in installments, or on a deferred basis in accordance with procedures established by the Compensation Committee.
 
  •  The Compensation Committee determines the material terms of the performance awards, including a performance period over which the performance goal of such award shall be measured, which must be at least 12 months and no longer than five years.
 
Deferrals
 
  •  The Compensation Committee may require or permit a participant to defer the receipt of cash or shares pursuant to any awards under the LTIP. Any deferral permitted under the LTIP will be administered in a manner that is intended to comply with Section 409A of the Code.
 
Effect of Certain Transactions and Change of Control
 
The following describes the effects of certain transactions and a change of control:
 
The Compensation Committee may provide in the terms of an award under the LTIP that, on a change of control as defined in the Plan (or award agreement, if awarded prior to April 26, 2010),
 
  •  options and SARs outstanding on the date of the change of control immediately vest;
 
  •  options and SARs outstanding on the date of the change of control may be cancelled and terminated without payment if the fair market value of a share of Common Stock on the date of the change of control is less than the per share option exercise price or SAR grant price;
 
  •  restrictions and deferral limitations on restricted stock lapse and the restricted stock becomes free of all restrictions and limitations and becomes fully vested;
 
  •  all performance awards shall be considered to be earned and payable and any deferral or other restriction shall lapse and the performance awards shall be immediately settled or distributed to the extent permitted under Section 409A of the Code;
 
  •  restrictions and deferral limitations and other conditions applicable to any other stock unit awards or any other awards lapse, and the other stock unit awards and other awards become free of all restrictions, limitations or conditions and become fully vested and transferable to the full extent of the original grant to the extent permitted under Section 409A of the Code; and
 
  •  such other additional benefits as the Compensation Committee deems appropriate shall apply.
 
The Compensation Committee, in its discretion, may determine that, upon a change of control, each option and SAR shall terminate within a specified period of days after notice to the participant, or that with respect to such option or SAR each participant shall receive an amount equal to the excess of the fair market value of such share immediately prior to the occurrence of the change of control over the exercise price per share of such option or SAR. The payment may be made in one or more kinds of stock or property or a combination of stock or property. Further, in the event of changes in the capital or corporate structure of Patterson-UTI due to events such as recapitalization, stock split, merger, spin-off or similar transaction, that affect the shares of Common Stock, the Compensation Committee, in its sole discretion, may determine that it is equitable or appropriate to make adjustments or substitutions to the Plan or outstanding options and awards, including to the number, class, kind and option or exercise price or securities subject to awards.


13


Table of Contents

Prior to April 26, 2010, the LTIP provided that the definition of a change of control of Patterson-UTI would be provided in an individual award agreement granted under the LTIP and that the Board retained the discretion to determine the events that constitute a change of control of Patterson-UTI. After April 26, 2010, the LTIP provides the change of control definition that is currently contained in the LTIP. Furthermore, the Board no longer retains the discretion to designate an event that is not described in the change of control definition as a change of control event.
 
Federal Income Tax Consequences
 
The following discussion summarizes certain federal income tax consequences of the issuance and receipt of awards pursuant to the LTIP under the law as in effect on the date of this proxy statement. The rules governing the tax treatment of such awards are quite technical, so the following discussion of tax consequences is necessarily general in nature and is not complete. In addition, statutory provisions are subject to change, as are their interpretations, and their application may vary in individual circumstances. This summary does not purport to cover all federal employment tax or other federal tax consequences associated with the LTIP, nor does it address state, local, or non-U.S. taxes.
 
ISOs
 
In general, a participant will not recognize income upon the grant or exercise of an ISO. However, if the participant is subject to federal “alternative minimum tax,” the exercise of an ISO will be treated essentially the same as a NQSO for purposes of the alternative minimum tax (see NQSOs, SARs, Performance Award, and Other Stock Unit Award below). Subject to certain exceptions for death or disability, if a participant exercises an ISO more than three months after termination of employment, the exercise of the option will be taxed as the exercise of a NQSO, as described below.
 
The general rule is that gain or loss from the sale or exchange of shares acquired on the exercise of an ISO will be treated as capital gain or loss. However, if shares acquired upon the exercise of an ISO are disposed of within two years from the date of grant or within one year after exercise (a “disqualifying disposition”), the participant generally will recognize ordinary income in the year of disposition in an amount equal to the fair market value of the shares at the time of exercise (or, if less, the amount realized on the disposition of the shares) less the exercise price. Any further gain (or loss) realized by the participant generally will be taxed as short-or long-term capital gain (or loss) depending on the holding period.
 
NQSOs, SARs, Performance Award, and Other Stock Unit Award
 
A participant generally is not required to recognize income on the grant of a NQSO, a SAR, performance award or other stock unit award. Instead, ordinary income generally is required to be recognized on the date the NQSO or SAR is exercised, or in the case of performance awards or other stock unit awards, upon the issuance of shares and/or the payment of cash pursuant to the terms of the award. In general, the amount of ordinary income required to be recognized is, (a) in the case of a NQSO, an amount equal to the excess, if any, of the fair market value of the shares on the exercise date over the exercise price, (b) in the case of a SAR, the fair market value of any shares received upon exercise plus the amount of taxes withheld from such amounts, and (c) in the case of performance awards or other stock unit awards, the amount of cash and/or the fair market value of any shares received in respect thereof, plus the amount of taxes withheld from such amounts.
 
Restricted Common Stock
 
Unless a participant who receives an award of restricted Common Stock makes an election under Section 83(b) of the Code as described below, the participant generally is not required to recognize ordinary income on the award of restricted Common Stock. Instead, on the date the shares vest (i.e., become transferable and no longer subject to forfeiture), the participant will be required to recognize ordinary income in an amount equal to the excess, if any, of the fair market value of the shares on such date over the amount, if any, paid for such shares. If a Section 83(b) election has not been made, any dividends received with respect to restricted Common Stock that are subject at that time to a risk of forfeiture or restrictions on transfer generally will be treated as compensation that is taxable as ordinary income to the recipient. If a participant makes a Section 83(b) election within 30 days of the date of transfer


14


Table of Contents

of the restricted Common Stock, the participant will recognize ordinary income on the date the shares are awarded. The amount of ordinary income required to be recognized is an amount equal to the excess, if any, of the fair market value of the shares on the date of award over the amount, if any, paid for such shares. In such case, the participant will not be required to recognize additional ordinary income when the shares vest. However, if the shares are later forfeited, a loss can only be recognized up to the amount the participant paid, if any, for the shares.
 
Gain or Loss on Sale or Exchange of Shares
 
In general, gain or loss from the sale or exchange of shares granted or awarded under the LTIP will be treated as capital gain or loss, provided that the shares are held as capital assets at the time of the sale or exchange. However, if certain holding period requirements are not satisfied at the time of a sale or exchange of shares acquired upon exercise of an ISO (a “disqualifying disposition,” see above), a participant generally will be required to recognize ordinary income upon such disposition.
 
Deductibility by Patterson-UTI
 
To the extent that a participant recognizes ordinary income in the circumstances described above, Patterson-UTI or its subsidiary for which the participant performs services will be entitled to a corresponding deduction, provided that, among other things, the income meets the test of reasonableness, is an ordinary and necessary business expense, is not an “excess parachute payment” within the meaning of Section 280G of the Code and is not disallowed by the $1 million limitation on certain executive compensation under Section 162(m) of the Code (see Performance Based Compensation and Parachute Payments below).
 
Performance Based Compensation
 
In general, under Section 162(m) of the Code, remuneration paid by a public corporation to its principal executive officer or its three most highly compensated executive officers (excluding the principal executive officer and the principal financial officer of the corporation), ranked by pay, is not deductible to the extent it exceeds $1 million for any year. Taxable payments or benefits under the LTIP may be subject to this deduction limit. However, under Section 162(m) of the Code, qualifying performance-based compensation, including income from stock options and other performance-based awards that are made under shareholder approved plans and that meet certain other requirements, is exempt from the deduction limitation. The LTIP has been designed so that the Compensation Committee in its discretion may grant qualifying exempt performance-based awards under the LTIP.
 
Parachute Payments
 
Under the so-called “golden parachute” provisions of the Code, the accelerated vesting of stock options and benefits paid under other awards in connection with a change of control of a corporation may be required to be valued and taken into account in determining whether participants have received compensatory payments, contingent on the change of control, in excess of certain limits. If these limits are exceeded, a portion of the amounts payable to the participant may be subject to an additional 20% federal tax and may be nondeductible to the corporation.
 
Withholding
 
Awards under the LTIP may be subject to tax withholding. Where an award results in income subject to withholding, Patterson-UTI may require the participant to remit the withholding amount to Patterson-UTI or cause shares of Common Stock to be withheld or sold in order to satisfy the tax withholding obligations.
 
Section 409A
 
Awards of SARs, performance awards, or other stock unit awards under the LTIP may, in some cases, result in the deferral of compensation that is subject to the requirements of Section 409A of the Code. Generally, if deferrals of these awards fail to meet the requirements of Section 409A of the Code, the compensation payable under these awards will be subject to immediate taxation and tax penalties in the year in which the awards vest. It is the intent of

Patterson-UTI that awards under the LTIP will be structured and administered in a manner that complies with the requirements of Section 409A of the Code.

All options are granted with an exercise price equal to or greater than the fair market value of the common stock at the time of grant. The vesting schedule and term are set by the Compensation Committee of the Board of Directors. All securities remaining available for future issuance under equity compensation plans approved by security holders in column (c) are available under this plan. None of the stock options, granted under the LTIP or any other equity compensation plan approved by security holders, have been granted with rights to receive cash dividends or dividend equivalent rights.
 
(2) The Amended and Restated Patterson-UTI Energy, Inc. 2001 Long-Term Incentive Plan (the “2001 Plan”) was approved by the Board of Directors in July 2001. In connection with the approval of the LTIP, the Board of Directors approved a resolution that no further options, restricted stock or other awards would be granted under any equity compensation plan, other than the LTIP. The terms of the 2001 Plan provided for grants of stock options, stock appreciation rights, shares of restricted stock and performance awards to eligible employees other than officers and directors. No Incentive Stock Options could be awarded under the Plan. All options were granted with an exercise price equal to or greater than the fair market value of the common stock at the time of grant. The vesting schedule and term were set by the Compensation Committee of the Board of Directors. None of the stock options granted under the 2001 Plan has been granted with rights to receive cash dividends or dividend equivalent rights.
 
Additional Information Regarding the LTIP
 
As of April 13, 2011, the closing price of Patterson-UTI’s common stock on the Nasdaq Global Select Market was $28.04 per share. Except for receipt of the option exercise price when and if options are exercised, Patterson-UTI receives no consideration in connection with the award of options or restricted stock under the LTIP. Except with respect to annual grants of restricted stock and stock options awarded to non-employee directors on an annual basis as discussed in the Director Compensation section of this Proxy Statement, Patterson-UTI has not determined the type, number and other terms of awards under the LTIP that will be granted in the future to eligible directors and

nominees, executive officers, officers as a group, or non-officer employees as a group as that determination is subject to the discretion of the Compensation Committee.
 
The Board of Directors recommends a vote “FOR” the approval of the material terms of the performance goals that may apply to performance-based awards under the LTIP. Approval of the material terms of the performance goals that may apply to performance-based awards under the LTIP requires the affirmative vote of the holders of a majority of the shares of Common Stock present in person or by proxy, and entitled to vote at the Meeting. If you do not vote against or abstain from voting on the performance goals under the LTIP, your proxy will be voted “FOR” approval of the performance goals under the LTIP. Abstentions will be counted as shares entitled to vote on the proposal and will have the same effect as a vote “AGAINST” the proposal. A broker non-vote will be counted for purposes of establishing a quorum, but will not be treated as a share entitled to vote on the proposal. This will have the effect of reducing the absolute number of shares necessary to approve the proposal.

ADVISORY VOTE ON EXECUTIVE COMPENSATION
 
In accordance with the recently adopted Section 14A of the Exchange Act, the Board of Directors is asking stockholders to approve a non-binding, advisory resolution on the compensation of Patterson-UTI’s executive officers who are named in the Summary Compensation Table appearing in this proxy statement (the “Named Executive Officers”). The compensation of Patterson-UTI’s Named Executive Officers is described in the “Compensation Discussion and Analysis” section of this proxy statement.
 
The compensation program for the Named Executive Officers is designed to attract and retain highly qualified individuals and to motivate and reward them for performance that benefits Patterson-UTI and its stockholders. The Compensation Committee and the Board of Directors believe that the policies and procedures detailed in the “Compensation Discussion and Analysis” achieve these goals by:
 
  •  providing a mix of short-term compensation in the form of base salary and cash bonuses and long-term compensation in the form of restricted stock, stock options and performance units, which strikes a balance between offering competitive compensation packages and aligning compensation with long-term growth and creating value for stockholders;
 
  •  setting annual base salaries, in part, based on Patterson-UTI’s financial results and position and performance compared to similarly situated companies;
 
  •  providing performance-based cash bonuses designed to put a meaningful portion of total compensation at risk;
 
  •  awarding stock options and performance units, whose value is tied to the achievement of certain performance goals and/or an increase in the price of the Common Stock;
 
  •  awarding stock options and restricted stock with vesting periods of three years; and
 
  •  establishing stock ownership guidelines.
 
As a matter of good corporate governance and in accordance with Section 14A of the Exchange Act, the Board of Directors is asking stockholders to approve the following non-binding, advisory resolution at the Meeting:
 
“RESOLVED, that the stockholders of Patterson-UTI Energy, Inc. (the “Company”) approve, on an advisory basis, the compensation of the Company’s named executive officers, as disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, the compensation tables and other narrative discussion in the Proxy Statement for the 2011 Annual Meeting of Stockholders of the Company.”
 
This advisory resolution, commonly referred to as a “say-on-pay” resolution, is non-binding on the Board of Directors. Although non-binding, the Board of Directors and the Compensation Committee value the views of Patterson-UTI’s stockholders and will review and consider the voting results when (i) evaluating the effectiveness of Patterson-UTI’s compensation policies and practices and (ii) making future compensation decisions for the Named Executive Officers.

The Board of Directors recommends a vote “FOR” the approval of the advisory resolution on executive compensation. Approval of the resolution, on an advisory basis, requires the affirmative vote of the holders of a majority of the shares of Common Stock present in person or by proxy, and entitled to vote at the Meeting. If you do not vote against or abstain from voting on the advisory resolution, your proxy will be voted “FOR” approval of the advisory resolution. Abstentions will be counted as shares entitled to vote on the proposal and will have the same effect as a vote “AGAINST” the proposal. A broker non-vote will be counted for purposes of establishing a quorum, but will not be treated as a share entitled to vote on the proposal. This will have the effect of reducing the absolute number of shares necessary to approve the proposal.

ADVISORY VOTE ON FREQUENCY OF
ADVISORY VOTES ON EXECUTIVE COMPENSATION
 
In accordance with Section 14A of the Exchange Act, the Board of Directors is asking stockholders to vote, on an advisory basis, on whether future advisory votes on the compensation of the Named Executive Officers should occur every year, every two years or every three years. Stockholders may also abstain from casting a vote on this proposal.
 
After careful review and consideration, the Board of Directors, on recommendation of the Compensation Committee, has determined that an advisory vote on the compensation of the Named Executive Officers should take place every year. In making its determination, the Board considered that an annual advisory vote on executive compensation will allow Patterson-UTI’s stockholders to provide their direct and timely feedback on Patterson-UTI’s compensation objectives, policies and practices.
 
This advisory vote on the frequency of future advisory votes on the compensation of the Named Executive Officers is non-binding on the Board. However, the Board of Directors and the Compensation Committee value the views of Patterson-UTI’s stockholders and will take into account the outcome of the voting when determining the frequency of such a vote. Stockholders will be able to specify one of four choices for this proposal on the proxy card: one year, two years, three years or abstain. Stockholders are not being asked to approve or disapprove the Board’s recommendation, but instead to indicate their choice among the frequency options (or to abstain).
 
The Board of Directors recommends a vote “FOR” approval, on an advisory basis, of a vote every year on executive compensation. Approval of the frequency of future advisory votes on executive compensation will be decided by the affirmative vote of a plurality of shares of the Common Stock present in person or by proxy, and entitled to vote at the Meeting. A “plurality” means that the frequency option that receives the greatest number of votes cast will be considered the preference of Patterson-UTI’s stockholders. If you do not vote against or abstain from voting, your proxy will be voted “FOR” approval of, on an advisory basis, a stockholder vote every year on executive compensation. Abstentions and broker non-votes will have no effect on the outcome of this vote.
 
PROPOSAL NO. 5
 
RATIFICATION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
 
The Audit Committee appointed PricewaterhouseCoopers LLP as the independent registered public accounting firm to audit the financial statements and internal control over financial reporting of Patterson-UTI for the fiscal year ending December 31, 2011, and directed that such engagement be submitted to the stockholders of Patterson-UTI for ratification. In recommending ratification by the stockholders of such engagement, the Board of Directors is acting upon the recommendation of the Audit Committee, which has satisfied itself as to PricewaterhouseCoopers LLP’s independence, professional competence and standing. Although ratification by stockholders of the engagement of PricewaterhouseCoopers LLP is not required by Delaware corporate law or Patterson-UTI’s restated certificate of incorporation or bylaws, the Audit Committee believes a decision of this nature should be made with the consideration of Patterson-UTI’s stockholders. If the stockholders fail to ratify the appointment, the Audit Committee will reconsider whether to retain PricewaterhouseCoopers LLP and may retain that firm or another without re-submitting the matter to our stockholders. Even if the appointment is ratified, the Audit Committee may,


18


Table of Contents

in its discretion, direct the appointment of a different independent registered public accounting firm at any time during the year if it determines that such change would be in the best interests of Patterson-UTI and its stockholders.
 
It is expected that one or more representatives of PricewaterhouseCoopers LLP will be present at the Meeting and will be given the opportunity to make a statement if they so desire. It also is expected that the representative(s) will be available to respond to appropriate questions from the stockholders.
 
The Board of Directors recommends a vote “FOR” the ratification of PricewaterhouseCoopers LLP as Patterson-UTI’s independent registered public accounting firm. Ratification of the selection of PricewaterhouseCoopers LLP requires the affirmative vote of the holders of a majority of the shares of Common Stock present in person or by proxy, and entitled to vote at the Meeting. Unless you give contrary instructions in your proxy, your proxy will be voted “FOR” such ratification. Abstentions will be counted as shares entitled to vote on the proposal and will have the same effect as a vote “AGAINST” the proposal. Because the ratification of an independent registered public accounting firm is considered a routine matter, if you do not give instructions to your brokerage firm, bank, broker-dealer, or other similar organization, the brokerage firm, bank, broker-dealer, or other similar organization will nevertheless be entitled to vote your shares in its discretion and may give or authorize the giving of a proxy to vote the shares in its discretion on this proposal.

COMPENSATION DISCUSSION AND ANALYSIS
 
Compensation Framework: Overview and Policies
 
Patterson-UTI’s executive compensation philosophy is to (i) link executive compensation with the operational and market performance of the Company and (ii) establish incentives that reward Patterson-UTI’s key executives for their efforts in achieving both short-term tactical and long-term strategic goals. The Compensation Committee (the “Committee”) seeks to offer to the Company’s key executives competitive compensation packages that will permit Patterson-UTI to attract and retain highly qualified individuals and to motivate and reward them for achieving the Company’s goals.
 
The Committee seeks to achieve a proper balance in its compensation program between current and long-term compensation by using a combination of fixed and variable cash for short-term incentives and time-vested equity awards for long-term incentives. In its program, the Committee emphasizes equity-based compensation over cash as a means of aligning the interests of management with the Company’s stockholders.
 
Our compensation policies are designed to take into account the cyclical and volatile nature of our industry, and in particular the impact on our results and operations of sometimes large and unpredictable swings in drilling activity as we experienced in 2009 and early 2010. The Committee believes that Patterson-UTI has a strong management team that works effectively and collaboratively. The Committee has designed our compensation program to foster this effective and collaborative management with shared compensation objectives and rewards.
 
We believe that our management and compensation policies have over the long run delivered superior returns to our stockholders, with total stockholder returns having been in the 67th and 90th percentiles over the past one and three years when measured against our peer group. We have delivered consistent strong returns on assets and equity over our history while maintaining a strong and low leveraged balance sheet.
 
Key Compensation Principles
 
Our compensation structure has historically emphasized the following three key principles:
 
The Use of Low Base Salaries and Higher Variable Cash Compensation Tied to Financial Results
 
The Committee has designed the cash compensation component of our program to be mostly variable by using comparatively low base salaries and higher cash bonuses tied to the Company’s annual earnings before interest, taxes, depreciation and amortization (“EBITDA”). The Committee adopted this program ten years ago and has allocated between 0.6111% and 1% of total EBITDA to an executive management pool that is then allocated among the top executive officers. Our current allocation is potentially 0.80%, which is allocated among Messrs. Siegel, Wall, Vollmer and Berns.
 
The use of lower market-based salaries with higher variable bonuses aligns our executives’ annual cash compensation with our actual financial results. During periods with low earnings, such as we had in 2009, total cash compensation will typically be in the lower quartiles against our peers but reflective of our results. During periods of higher earnings, cash compensation will typically be in the top quartiles and reflective of the Company’s higher cash generation. Accordingly, the Committee has designed our program as a multi-year program that is targeted to provide cash compensation to our top four Named Executive Officers that is in the 50-65th percentile as a group on a full cycle basis with an expectation that over the cycle, stockholder returns will also be within that range.
 
Although there will sometimes be periods where cash compensation is in the higher quartiles and relative stock performance is at a lower quartile or vice versa, this result generally occurs during a period of market change where there exists a difference between market outlook and current activity. A good example of this was the end of 2008


20


Table of Contents

where activity and operating results were strong, but the public market value for land drillers was falling on the expectation of a severe downturn that did occur in 2009.
 
The Committee has generally not changed base compensation for the top Named Executive Officers from year to year to promote the idea that management should not focus on the fixed compensation, and management should expect that variable compensation — tied to the Company’s performance — will be the most significant part of compensation.
 
The Committee has considered in the past the use of more traditional bonus plans tied to annual budgets and performance against budgets and has concluded that with the extreme volatility in our industry those plans would not provide the incentives that the Committee is seeking to achieve and could in fact create incentives to focus only on the short-term. By tying a meaningful portion of the top four Named Executive Officers’ compensation to EBITDA, the Committee believes that their compensation and the stockholders’ interests are especially well aligned.
 
The Committee has for 2011 modified our annual cash compensation plan for our top four Named Executive Officers from 0.6111% of EBITDA to a maximum of 0.80% of EBITDA to allow for the potential for additional payments based on exceptional performance against our strategic objectives. The 2011 plan also provides for a downward adjustment in the EBITDA-based payout for relative underperformance against strategic measures.
 
Emphasis on Equity for Long-term Incentive Compensation
 
The Committee has historically targeted more than 60% of total compensation to be in the form of equity or equity-based compensation. This emphasis on equity-based compensation is aimed at aligning the financial interest of top Named Executive Officers with our stockholders and the total returns provided to stockholders. The Committee believes that by making a large portion of compensation tied to equity, our top Named Executive Officers will generally fully realize the potential benefits of the compensation only if our stockholders also benefit.
 
Over the years the Committee has adjusted the form of the equity incentives provided to our top Named Executive Officers from solely options to a current mix of options, restricted stock and performance units. The Committee believes that this mix allows it to tailor our program to encourage the building of long-term value and, in the case of performance units, achievement of stockholder returns in excess of a peer group.
 
Restricted Stock.  The Committee views restricted stock as additional basic compensation that will provide value only if the executive remains in the employment of the Company during the vesting period, with that value being subject to increases and decreases in value depending on the performance of Patterson-UTI’s stock. The Committee typically targets restricted stock to be approximately 30-40% of the equity compensation.
 
Stock Options.  The issuance of stock options is intended to offer equity incentives that provide value to the executive only if the Company’s stock appreciates. When the Committee grants options to our executives, it considers a number of different factors, including the stock value at the time of grant, the Black Scholes value of the option grant for accounting purposes and prior option grant amounts. In addition to considering the Black Scholes option value, the Committee may also consider other option valuation models and modifications to the Black Scholes model to address situations where historical volatility may not be representative of a normalized market. The high volatility that we have seen in our and other companies’ stock prices since the financial crisis in 2008 has created a situation where the impact of volatility on value needs to be considered as it can skew the calculated value and therefore the perceived value of an executive’s compensation package.
 
Ultimately, the Committee’s decision on the number of options granted in any year will be based on the circumstances at the time and consideration of a variety of factors, with the overriding objective being the expectation of the potential value the option may provide in light of current market prices, where Patterson-UTI is in the business cycle and Patterson-UTI’s long-term value creation objectives.
 
Performance Units.  The Committee added performance units to the mix of equity-based compensation in 2009. The Committee added the performance units in lieu of a portion of restricted stock and options that it would have granted. The use of performance units is intended to tie the top four Named Executive Officers’ compensation to the relative outperformance of Patterson-UTI as an investment relative to its peer group. This component assures


21


Table of Contents

that the value provided to those Named Executive Officers will not be created solely by an increase in stock price due to market conditions, but also requires outperformance.
 
The Committee has considered the potential risks associated with providing a large portion of executive compensation tied to equity. For the following reasons the Committee does not believe that the use of such equity grants creates unreasonable risks. First, the long-term nature of the equity awards and the required vesting periods help minimize the potential of excessive risk taking and actions aimed at short-term stock gains. Second, the combination of different types of equity grants, in particular the use of restricted stock, help offset risks. Finally, the top four Named Executive Officers each have worked with the Company for at least four years and three of them have worked with the Company for more than ten years, and the Committee believes management to be highly ethical and focused on creating true long-term value for stockholders and not just short-term gains. The Board and the Committee monitor and consider risks associated with the Company’s compensation plans.
 
Team Compensation Structure
 
For more than the past ten years our senior executive management has had the philosophy that they operate as a team, with each member being an important part of the team. As a result, they have requested, and the Board and the Committee have agreed, that as a general proposition cash and equity incentive compensation be allocated and shared among the team. Although the allocations have changed over time as a result of changes to the executive management team, the allocations among the existing team have generally remained consistent.
 
When allocating the incentive compensation among the top Named Executive Officers, the Committee currently allocates 2/5.5th to Mr. Siegel, our Executive Chairman, 1.5/5.5th to Mr. Wall, our President and Chief Executive Officer, and 1/5.5th to each of Mr. Vollmer, our Senior Vice President-Corporate Development, Chief Financial Officer and Treasurer, and Mr. Berns, our Senior Vice President, respectively.
 
The Committee believes that the above approach for compensating our top four Named Executive Officers fosters effective decision-making and collaborative efforts in executing Patterson-UTI’s long-term strategic and short-term tactical objectives. This approach has worked well for Patterson-UTI for ten years. In addition, although the Committee will continue to monitor the team compensation approach to make sure the process works in practice, the Committee expects to continue to use this approach in the future.
 
Board and Committee Processes and Grant Policies
 
Committee Review Process
 
The Board of Directors has delegated the management of the Company’s executive compensation programs to the Committee. The Committee meets on a regular basis to consider compensation matters and to review how the Company’s plans and policies work in practice. The Committee currently consists of Messrs. Hunt (chairman), Buckner, Huff and Peak, each of whom is an independent director as defined by the Nasdaq listing standards.
 
Compensation determinations and equity awards by the Committee are conducted through a process that seeks the input from management through Mr. Siegel as well as from outside compensation consultants retained by the Committee. Consultants used by the Committee are independent and are paid on a basic fixed fee structure plus expenses. The Committee has retained Pearl Meyer & Partners as consultant and advisor for executive compensation matters for 2011. The Committee also considers internal budgets, historical data for the Company and its peers, strategic planning updates and other relevant information.
 
The Committee uses the outside consultant reports as a tool for obtaining information on historical compensation and stockholder returns, market trends and peer compensation practices. The Committee further seeks the advice of its consultants to confirm that the final compensation arrangements established by the Committee are reasonable.
 
When considering peer compensation data, the Committee considers data for both individual positions and for the top Named Executive Officers as a whole. The Committee has generally given greater weight to the peer data for the team as a whole versus the individual positions at its peers given the team management approach followed by the Company. The Committee has found that total compensation for its top Named Executive Officers as a group has


22


Table of Contents

typically been around the 50-75th percentile range depending on the year and that under the Company’s team-based approach there has typically been a shift of compensation from the top two Named Executive Officers to the rest of the team.
 
The Company has in recent years used the following peer group for compensation matters: Cameron International Corporation, Diamond Offshore Drilling Inc., Ensco International Inc., FMC Technologies Inc., Helmerich & Payne Inc., Nabors Industries Ltd., National Oilwell Varco Inc., Noble Corp., Pride International, Inc., Rowan Companies Inc., Transocean Ltd. and Weatherford International Ltd. In 2010, the Committee added eight additional companies to the peer group in order to gain a broader perspective on the competitive market place and to include some smaller drilling and service companies in its peer group. The companies added were: Atwood Oceanics, Baker Hughes Incorporated, Basic Energy Services, Inc., Bronco Drilling Company, Inc., Key Energy Services, Inc., Parker Drilling Company, Pioneer Drilling Company, and Unit Corp. BJ Services Company and Smith International, Inc. have also been included in prior years, but will be eliminated from the peer group going forward due to their having been acquired in 2010.
 
Cash Compensation
 
The Committee generally sets base compensation and terms for bonus cash compensation for management in the fourth quarter of the preceding year or in the first quarter of the year in question. The Committee when reviewing cash compensation looks at the total cash compensation received by the executives over a multi-year period as well as the total cash compensation projected for the current year. This approach allows the Committee to look at the cash compensation paid over a full cycle in order to obtain comparable data for benchmarking purposes. The Committee also annually establishes the performance criteria for the cash bonus compensation paid to its executives in order to meet the requirements for the performance-based compensation exception to the limitation on deductions under Section 162(m) of the Internal Revenue Code (as further described elsewhere in this proxy statement). Although a wide range of criteria may be used, the criterion used has historically been the achievement of a threshold EBITDA amount.
 
Equity Compensation
 
The Committee’s practice has generally been to grant any stock options, restricted stock and performance units to executive management at a meeting following the conclusion of Patterson-UTI’s first quarter. This meeting is typically held in conjunction with regular quarterly Board meetings that are held prior to Patterson-UTI’s public release of quarterly earnings information. This timing also allows the Committee to have received market data for prior year grants.
 
The Committee considers a number of factors when determining equity grants, including competitive peer data, prior year grants and current and historical stock prices. The Committee also takes into consideration the advice of its consultants as to peer and market practices on the use and mix of restricted stock, options and performance units.
 
For restricted stock and stock options, these awards are subject to three-year vesting with one-third vesting after the first year and 1/36th of the grant vesting each month over the next two years. The performance units granted in 2010 are to be settled with shares of stock, with the number of shares to be issued based on the Company’s total stockholder return at the end of the third year following the grant relative to the total stockholder return for our peer group of companies. Subject to limited exceptions, no payout will be provided on performance units unless the Company’s relative total stockholder return against its peers is at least at the 25th percentile and the Company has a positive stockholder return.
 
The Company has also adopted the following additional practices regarding its equity grants:
 
  •  Grants will not vest in less than one year;
 
  •  Options will not be re-priced or exchanged;
 
  •  Equity grants are subject to claw-back in the event that the Board learns that any misconduct by the Named Executive Officer contributed to the Company having to restate all or a portion of its financial statements;


23


Table of Contents

 
  •  Options are to have exercise prices equal to or greater than the fair market value on the date of grant; and
 
  •  Performance targets are not to be modified other than to give effect to acquisition or disposition of businesses or similar structural changes — market condition changes will not result in changes in performance targets.
 
Overview of 2010 Performance and Compensation
 
In 2009, the Patterson-UTI Board of Directors adopted a long-term strategic plan that included: (i) diversifying its customer base and increasing market share, upgrading its rig fleet and providing superior value to its customers in land drilling, (ii) expanding its pressure pumping business, (iii) being nimble both in operations and in strategic decisions, and (iv) providing superior returns to its stockholders.
 
From January 1, 2009 through December 31, 2010, the Company has:
 
  •  Added 39 new high technology APEXtm rigs, bringing the total to 66 at the end of 2010, an increase of over 140%;
 
  •  Expanded its customer base and secured additional long-term drilling contracts to finance its rig expansion;
 
  •  Built a reputation for rig design innovation and being one of the most efficient drillers in the industry;
 
  •  Increased its market share and has become a significant player in many of the new shale plays, including the Marcellus;
 
  •  Increased its pressure pumping horsepower in Appalachia by approximately 85 percent;
 
  •  Acquired in 2010 the pressure pumping business of Key Energy and expanded its pressure pumping capabilities;
 
  •  Disposed of Patterson-UTI’s non-core drilling fluids business at an attractive price;
 
  •  Managed through the downturn of 2009 and 2010 successfully at a time where Patterson-UTI saw its rig count fall to a low of 60 for the month of June 2009 and recover to approximately 200 at the end of 2010; and
 
  •  Provided top quartile stockholder returns.
 
2010 Accomplishments
 
The oil and gas industry went through significant challenges during 2010. Following the financial crisis in 2008, U.S. drilling activity plummeted in early 2009 by over 50% from its prior highs in October 2008. By 2010 the industry began to recover with the expansion of the natural gas shale plays in the U.S. and an increase in drilling for oil. Drilling processes also changed during this period from being predominately vertical to more than 60% horizontal today. With the change in drilling methods, came a need for higher technology rigs and higher drilling efficiencies.
 
Patterson-UTI’s efforts over the past few years positioned the Company and its rig fleet to take advantage of the change in drilling methods and the need for higher technology rigs. As a result, Patterson-UTI was able to nearly double its consolidated revenue base from $782 million in 2009 to $1.46 billion in 2010 and increase its consolidated EBITDA 124% to $536 million in 2010. During this period, the Company added 19 new rigs, entered into long-term contracts for over 70 rigs and grew its market share to number one in the combined U.S. market in which Patterson-UTI conducts business in terms of operating rigs as of the end of 2010.
 
The Company’s pressure pumping business similarly grew in 2010 to a record $351 million in revenue and $103 million in EBITDA from $161 million in revenues and $28.6 million in EBITDA in 2009. The well-timed acquisition of Key Energy’s pressure pumping business in the fourth quarter of 2010 at a net cost of less than $1,000 per horse power doubled the size of the Company’s second core business and further accelerated the growth of this business segment. This segment is expected to continue to grow and become a greater part of the Company’s overall business.

During 2010, the Company also divested its non-core drilling fluids business and certain oil and gas properties, the proceeds of which were used to grow the Company’s core businesses. The Company also expanded access to capital for expansion in 2010 by completing bank and private placement financings.
 
2010 Compensation
 
Cash Compensation
 
Under the terms of the Company’s cash compensation plan described above, the top four Named Executives Officers earned the following cash payments in respect of 2010. These payments were determined based on the salaries and incentive compensation percentages determined for the named individuals at the beginning of 2010 and were not adjusted. The incentive compensation was calculated by taking the Company’s $536 million in EBITDA and multiplying it by the EBITDA percentages noted below. The Committee had fixed a $200 million minimum EBITDA threshold for 2010, which was exceeded.

The maximum amount that can be awarded to an individual under our cash-based incentive plan during a 12-month period is $5,000,000. In order to reach this maximum amount, EBITDA of $2.25 billion in the case of Mr. Siegel, $3.00 billion in the case of Mr. Wall and $4.50 billion in the case of Messrs. Vollmer and Berns would have been needed. The Committee did not establish a target bonus amount. The target bonus amount presented in the Grants of Plan-Based Awards table is calculated for the respective officer based on Patterson-UTI’s actual EBITDA for the fiscal year ended December 31, 2010 and the allocation formula applied to the bonus pool for distribution.
 
Equity-Based Compensation
 
The Company made the following equity-based grants to the top four Named Executive Officers. The grant of restricted stock, options and performance units to such officers were made following the vesting, term and other criteria described above.

(1) Shares of restricted stock were awarded on April 27, 2010 and the value indicated in the table is the value on the date of grant based on the closing price of Patterson-UTI’s common stock on April 27, 2010.
 
(2) Options were awarded on April 27, 2010 and the value indicated in the table was determined using the Black-Scholes option pricing model as of the date of grant.

(3) Performance Units were awarded on April 27, 2010. The number of shares indicated in the table represents the base number of shares for each respective award. According to the terms of the awards, the actual number of shares earned by the recipient can range from zero to four times the base number depending on how Patterson-UTI performs in terms of total stockholder return relative to its peer group. The value indicated in the table was determined based on a Monte-Carlo simulation model and represents the estimate of fair value on the date of grant.
 
The performance units granted in 2010 to the top four Named Executive Officers provide for the issuance of 32,500 shares of Common Stock to Mr. Siegel, 24,375 shares of Common Stock to Mr. Wall and 16,250 shares of Common Stock to each of Messrs. Vollmer and Berns, respectively, if Patterson-UTI’s total stockholder return is at or above the 25th percentile but less than the 50th percentile, two times that number of shares if Patterson-UTI’s total stockholder return is at or above the 50th percentile but less than the 75th percentile and four times that amount if Patterson-UTI’s total stockholder return is 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.
 
Total stockholder return for Patterson-UTI for the 2010 performance unit grants is measured based on $100 invested in Common Stock on the first day of the performance period, with dividends reinvested. The performance period is the period from April 1, 2010 through March 31, 2013, subject to certain exceptions that could extend the performance period up to two additional years. No shares will be issued in respect of the performance units unless Patterson-UTI has positive total stockholder return as of the end of the performance period; except that if during the two-year period ending after the performance period, Patterson-UTI’s total stockholder return for any 30 consecutive day period equals or exceeds 18% on an annualized basis from the beginning of the performance period through the end of such 30 consecutive day period, then shares issued under the grant will be made as set forth above based on Patterson-UTI’s total stockholder return relative to the peer group as of end of the performance period.
 
Total Compensation and Relationship to Performance
 
The Committee considered the advice of Towers Watson when establishing its 2010 compensation program. In doing so, the Committee sought to offer a total compensation package (cash and long-term) for the top four Named Executive Officers as a group that would be between the 50th and 75th percentile. Based on early 2011 proxy data for Patterson-UTI’s peers, the Committee was able to confirm that the compensation provided in 2010 for Patterson-UTI’s top four Named Executive Officers was approximately 70th percentile against its peers. This compensation compares favorably to Patterson-UTI’s 67th percentile total stockholder return performance in 2010 and 90th percentile performance over the past three years.
 
The Committee believes that Patterson-UTI has a strong and cohesive management team and that the compensation policies that it has implemented provide the proper mix of current compensation and long-term incentives for building stockholder value. The Company’s above market performance has supported the use of these policies and align the interest of management with the Company’s stockholders.
 
With respect to the Company’s executive officers other than the top Named Executive Officers, the Committee has historically determined their compensation with a philosophy of using a combination of fixed and variable cash in the form of base salary and discretionary cash bonuses for short-term incentives and time-vested equity awards in the form of restricted stock and/or stock options for long-term incentives. With respect to Mr. Wexler’s compensation for 2010, his incentive compensation was determined at the discretion of the Committee. Mr. Wexler’s non-equity incentive compensation was determined based on the operating performance of Patterson-UTI and his individual performance, and his equity-based, long-term incentive compensation was awarded in the form of restricted stock.
 
Employment and Termination Agreements and Other Matters
 
Retirement Plans
 
Patterson-UTI offers a 401(k) plan to its employees, including its Named Executive Officers. Participants may contribute a portion of their base salary to the 401(k) plan, subject to federal limits. Patterson-UTI makes matching


26


Table of Contents

contributions up to four percent of each participant’s eligible base salary. The Named Executive Officers of Patterson-UTI are eligible to participate in the 401(k) plan on the same basis as other employees. Patterson-UTI does not have any other retirement plan.
 
Perquisites and Personal Benefits
 
No Named Executive Officer received perquisites totaling more than $10,000. Accordingly, the perquisites do not meet the threshold that would require disclosure in the Summary Compensation Table below.
 
Share Ownership Guidelines
 
The Nominating and Corporate Governance Committee has enacted share ownership guidelines applicable to all executive officers and directors of Patterson-UTI. The guidelines require officers and directors to hold at all times, subject to a four year phase-in from the date first elected as an officer or director, at least the following number of shares of Common Stock:
 
                 
      Executive Chairman     120,000 shares  
      President and Chief Executive Officer     90,000 shares  
      Senior Vice Presidents     60,000 shares  
      General Counsel     7,500 shares  
      Chief Accounting Officer     7,500 shares  
      Outside Directors     10,000 shares  
      Non-executive Inside Director     10,000 shares  
 
Each of the Named Executive Officers and Directors was in compliance with these guidelines as of the date of this proxy statement.
 
Change in Control and Severance Agreements
 
Patterson-UTI has entered into change in control agreements with its Named Executive Officers as further described elsewhere in this proxy statement The Company, however, believes that such agreements may under certain circumstances protect the interest of the Company from leaving employment out of concern for the security of their jobs or being unable to concentrate on their work. The Committee believes that the change in control agreements may also help Patterson-UTI to attract and retain new key employees by reducing the personal uncertainty and anxiety that arises from the possibility of a future business combination. Any future change in control or severance agreements will be approved subject to the circumstances existing at the time.
 
Patterson-UTI has entered into written letter agreements with each of Messrs. Siegel, Berns and Vollmer pursuant to which Patterson-UTI has agreed to pay each such person within ten days of the termination of his employment with Patterson-UTI for any reason (including voluntary termination by him), an amount in cash equal to his annual base salary at the time of such termination. Any payment made by Patterson-UTI pursuant to these letter agreements will reduce dollar for dollar any payment owed to such person, if any, pursuant to the change in control agreements discussed above.
 
Section 162(m) Considerations
 
In considering compensation decisions for the executive management of Patterson-UTI, the Committee routinely considers the potential effect of Section 162(m) of the Internal Revenue Code. Section 162(m) imposes a limitation on corporate tax deductions for non-performance based compensation to certain officers that exceeds $1 million that can be taken by a publicly held corporation for compensation paid to certain of its executive officers. While Patterson-UTI does not design its compensation programs for tax purposes, Patterson-UTI does design its plans to be tax efficient for Patterson-UTI where possible. However, the Committee believes that tax deduction limitations should not compromise Patterson-UTI’s ability to establish and maintain appropriate executive compensation programs and reserves the right to award non-deductible compensation.

(1) The 2010 bonus plan for Named Executive Officers for the fiscal year ended December 31, 2010 was approved on February 9, 2010. The 2010 bonus plan for Messrs. Wall, Vollmer, Siegel and Berns provided for a bonus pool based on EBITDA for the fiscal year ended December 31, 2010, subject to a minimum EBITDA of $200 million. The bonus pool was allocated among Messrs. Wall, Vollmer, Siegel and Berns based on a pre-determined sharing percentage. The threshold amount presented in this table is calculated for the respective officer based on an assumed EBITDA of $200 million and the allocation formula applied to the bonus pool for distribution due to the fact that the bonus plan provides for no payment if the minimum EBITDA of $200 million is not satisfied. The target amount is calculated based on Patterson-UTI’s actual EBITDA for the fiscal year ended December 31, 2010 and the allocation formula applied to the bonus pool for distribution. The cash bonuses awarded from the bonus pool were awarded under the LTIP, which has been designed to meet the requirements of Section 162(m) of the Code. Although the bonus pool for Messrs. Wall, Vollmer, Siegel and Berns did not have an EBITDA cap, the maximum amount that could be awarded to an individual under any cash-based performance award granted under the LTIP during a 12-month period is $5,000,000.
 
(2) On April 27, 2010, Patterson-UTI granted performance unit awards to Messrs. Wall, Vollmer, Siegel and Berns. These awards provide for the recipients to receive shares of Common Stock upon the achievement of certain performance goals established by Patterson-UTI during a specified period. The performance period is the period from April 1, 2010 through March 31, 2013, subject to certain exceptions that could extend the performance period up to two additional years, as described in “Compensation Discussion and Analysis” above. The performance goals are tied to Patterson-UTI’s total shareholder return for the performance period as compared to total shareholder return for a peer group determined by the Compensation Committee. If Patterson-UTI’s total shareholder return for the performance period is positive and at or above the 25th percentile but less than the 50th percentile in relation to the peer group, the awards provide for the grant of a base number of shares. If Patterson-UTI’s total shareholder return for the performance period is positive and above the 50th percentile but less than the 75th percentile in relation to the peer group, the awards provide for the grant of two times the base number of shares. If Patterson-UTI’s total shareholder return for the performance period is positive and above the 75th percentile in relation to the peer group, the awards provide for the grant of four times the base number of shares. The grant of shares when achievement is between the 25th and 75th percentile will be determined on a pro-rata basis. The target number of shares presented in the table are based on Patterson-UTI’s total shareholder return at the end of the performance period being positive and at the 50th percentile in relation to the peer group.
 
(3) Shares of restricted stock were awarded pursuant to the LTIP. Ordinary dividends are paid on unvested shares of restricted stock. The rate at which these dividends are paid is the same rate at which ordinary dividends are paid on all other shares of common stock of Patterson-UTI. The right to receive these dividends has been included in the grant date fair value of stock awards presented in the table. The shares awarded to Messrs. Wall, Vollmer, Siegel and Berns vest over a three year period as follows: one-third on April 27, 2011, and the remaining two-thirds in equal monthly installments over the twenty-four months following April 27, 2011. The shares awarded to Mr. Wexler vest over a three year period as follows: one-third on June 9, 2011, one-third on June 9, 2012 and one-third on June 9, 2013.
 
(4) Options were granted pursuant to the LTIP. Options awarded to Messrs. Wall, Vollmer, Siegel and Berns vest over a three year period as follows: one-third on April 27, 2011, and the remaining two-thirds in equal monthly installments over the twenty-four months following April 27, 2011.
 
(5) The grant date fair value of restricted stock is based on the closing price of Patterson-UTI Common Stock on the date of grant, which is consistent with the valuation used by Patterson-UTI for the recognition of compensation expense under FASB ASC Topic 718. The grant date fair value of stock options was determined using the Black-Scholes option pricing model, which is consistent with the valuation used by Patterson-UTI for the recognition of compensation expense under FASB ASC Topic 718, with assumptions that are more fully described in Note 11 to the consolidated financial statements in Patterson-UTI’s Annual Report on Form 10-K for the fiscal year ended December 31, 2010.

(2) As discussed in footnote (2) to the Grants of Plan Based Awards table, on April 27, 2010, Patterson-UTI granted performance unit awards to Messrs. Wall, Vollmer, Siegel and Berns. The number of shares presented in this column represents the base number of shares for the respective awards. Based on Patterson-UTI’s total shareholder return during the performance period ending March 31, 2013, the recipients could receive a number of shares ranging from no shares to four times the base number of shares. Performance unit awards

Table of Contents

were granted in 2009 to Messrs. Wall, Vollmer, Siegel and Berns which were denominated in dollars and provided for a cash payout based on Patterson-UTI’s total shareholder return during the performance period ending March 31, 2012. Since these awards provide for no issuance of shares they are not included in this column.
 
(3) As of December 31, 2010, performance unit awards had been granted to Messrs. Wall, Vollmer, Siegel and Berns. The 2009 performance unit awards were granted on April 28, 2009 and provide for a cash payment to the recipient based on Patterson-UTI’s total shareholder return compared to a peer group of companies for the performance period from April 1, 2009 through March 31, 2012. The 2010 performance unit awards were granted on April 27, 2010 and provide for an award of shares of Patterson-UTI common stock to the recipient based on Patterson-UTI’s total shareholder return compared to a peer group of companies for the performance period from April 1, 2010 through March 31, 2013. All performance unit awards provide for a threshold payout (in dollars for the 2009 awards and in shares for the 2010 awards) based on threshold level of total shareholder return compared to the peer group. Due to the fact that the performance periods for all awards had not been completed as of December 31, 2010, the amounts presented in this column represent the threshold payout under the performance unit awards. For the 2010 performance unit awards, the threshold number of shares is valued at the December 31, 2010 closing price of Patterson-UTI common stock which was $21.55 per share.

(3) Mr. Talbott retired from his position as President and Chief Executive Officer of Patterson-UTI on September 30, 2007. Patterson-UTI entered into an employment agreement with Mr. Talbott effective October 1, 2007 which provided for the employment of Mr. Talbott on a part-time basis for a period of five years. Mr. Talbott’s salary during the term of this employment agreement is $250,000 per year.
 
Directors who are also employees of Patterson-UTI do not receive compensation for serving as a director or as a member of a committee of the Board of Directors. All directors are reimbursed for reasonable out-of-pocket expenses incurred in connection with serving as a member of the Board of Directors. Each non-employee director receives annual cash compensation of $35,000 and (i) 3,000 shares of restricted stock subject to one-year vesting (subject to acceleration in certain limited situations, including a change of control) and (ii) an option to purchase 10,000 shares of Common Stock at an exercise price equal to the closing price of Common Stock on the grant date. The option has a 10-year term, vests after one-year (subject to acceleration in certain limited situations, including a change of control) and contains a right to exercise for three years following cessation of the holder as a director (but not beyond the 10-year term). Each non-employee director that serves on the Audit Committee or the Compensation Committee receives additional annual cash compensation of $10,000 per committee on which he serves, with the chairman of each such committee receiving $15,000. In March 2010, the Compensation Committee authorized additional annual cash compensation of $20,000 to the Lead Director.
 
CHANGE IN CONTROL ARRANGEMENTS;
INDEMNIFICATION AGREEMENTS; CERTAIN PAYMENTS
 
Patterson-UTI has entered into change in control agreements with Messrs. Siegel, Wall, Berns, Vollmer and Wexler (each agreement, an “Agreement” and collectively, the “Agreements”; and each individual, an “Employee and collectively, the “Employees”). The Agreements were entered into to protect the Employees should a change in control occur, thereby encouraging the Employee to remain in the employ of Patterson-UTI and not be distracted from the performance of his duties to Patterson-UTI by the possibility of a change in control.
 
In the event of a change in control of Patterson-UTI in which an Employee’s employment is terminated by Patterson-UTI other than for cause or by the Employee for good reason, the terms of the Agreements would entitle the Employee to, among other things:
 
  •  a bonus payment equal to the highest bonus paid after the Agreement was entered into (such bonus payment prorated for the portion of the fiscal year preceding the termination date),
 
  •  a payment equal to 2.5 times (in the case of Messrs. Siegel and Wall), 2.0 times (in the case of Messrs. Berns and Vollmer) or 1.5 times (in the case of Mr. Wexler) of the sum of (i) the highest annual salary in effect for such Employee during the term of the Agreement and (ii) the average of the three annual bonuses earned by the Employee for the three fiscal years preceding the termination date (or a benchmark bonus in the case of Mr. Wexler), and
 
  •  continued coverage under Patterson-UTI’s welfare plans for up to three years (in the case of Messrs. Siegel and Wall) or two years (in the case of Messrs. Berns, Vollmer and Wexler).
 
Each Agreement provides the Employee with a full gross-up payment for any excise taxes imposed on payments and benefits received under the Agreements or otherwise, including other taxes that may be imposed as a result of the gross-up payment.
 
A “change in control” is principally defined by the Agreement as:
 
  •  an acquisition by any individual, entity or group of beneficial ownership of 35% or more of either Patterson-UTI’s then outstanding Common Stock or the combined voting power of the then outstanding voting securities of Patterson-UTI entitled to vote in the election of directors,


34


Table of Contents

 
  •  a change occurs in which the members of the Board of Directors as of the date of the Agreement cease to constitute at least a majority of Patterson-UTI’s Board of Directors unless that change occurs through a vote of at least a majority of the incumbent members of the Board of Directors, or
 
  •  a change in the beneficial ownership of Patterson-UTI following consummation of a reorganization, merger, consolidation, sale of Patterson-UTI or any subsidiary of Patterson-UTI or a disposition of all or substantially all of the assets of Patterson-UTI, in which the beneficial owners immediately prior to the transaction own 65% or less of outstanding Common Stock of the newly combined or merged entity.
 
The Agreements terminate on the first to occur of:
 
  •  the Employee’s death, disability or retirement,
 
  •  the termination of the Employee’s employment, or
 
  •  January 29, 2012 although, unless otherwise terminated, the Agreements automatically renew for successive twelve-month periods until Patterson-UTI notifies the Employee at least 90 days before the expiration of the initial term or the renewal period, as applicable, that the term will not be extended. Patterson-UTI has not provided any such notification to the Employees.
 
All unvested stock options and restricted stock awards held by Named Executive Officers vest upon a change of control as defined by the underlying award agreements. Upon a change in control as defined in the underlying performance unit award grants, Messrs. Wall, Vollmer, Siegel and Berns would receive two times the base payment payable thereunder. All restricted stock and performance unit awards held by Named Executive Officers contain provisions that in the event of termination due to death or disability, the Named Executive Officer would vest in a portion of the award.
 
Patterson-UTI has entered into written letter agreements with each of Messrs. Siegel, Berns and Vollmer pursuant to which Patterson-UTI has agreed to pay each such person within ten days of the termination of his employment with Patterson-UTI for any reason (including voluntary termination by him), an amount in cash equal to his annual base salary at the time of such termination. Any payment made by Patterson-UTI pursuant to these letter agreements will reduce dollar for dollar any payment owed to such person, if any, pursuant to the change in control agreements discussed above.
 
Amounts that each of the Named Executive Officers would be entitled to under the existing Agreements if a change in control had occurred as of December 31, 2010 and the employee’s employment was terminated by Patterson-UTI other than for cause or by the employee for good reason (as defined in the Agreements) are reflected in the following table:

(3) Cash settled performance units awarded to Messrs. Wall, Vollmer, Siegel and Berns in 2009 include a provision that upon a change in control as defined in the respective award agreements, the Named Executive Officer will receive a cash payment equal to two times the base amount set forth in each agreement. Amounts presented in the table represent the assumed payment of two times the base amount if a change in control had occurred on December 31, 2010.
 
(4) Each of the Named Executive Officers’ option and stock award agreements provide that unvested options and awards will immediately vest upon a change in control. Amounts presented in the table represent the value of unvested option and stock awards using the market price of Patterson-UTI Common Stock at December 31, 2010.
 
(5) Share settled performance units awarded to Messrs. Wall, Vollmer, Siegel and Berns in 2010 include a provision that upon a change in control as defined in the respective award agreements, the Named Executive Officer will receive an award of shares equal to two times the base amount set forth in each agreement. Amounts presented in the table represent the assumed award of two times the base number of shares if a change in control had occurred on December 31, 2010 valued at the December 31, 2010 closing price of Patterson-UTI common stock of $21.55 per share.
 
(6) Messrs. Wall, Vollmer and Wexler participated in Patterson-UTI’s health and welfare plans as of December 31, 2010. The amounts presented represent Patterson-UTI’s portion of the premiums for three years in the case of Mr. Wall and two years in the case of Messrs. Vollmer and Wexler based on the rates in effect at December 31, 2010.
 
(7) Assumes Mr. Wall would be subject to an excise tax on payments received under the existing agreements if a change in control had occurred as of December 31, 2010. Amount presented in the table represents the gross-up payment that Mr. Wall would be entitled to as a result of the imposition of the excise tax.
 
All restricted stock and performance unit awards held by Named Executive Officers provide that in the event of termination of employment due to death or disability, the Named Executive Officer would vest in a portion of the award. With respect to Mr. Wall, such a termination would have resulted in the accelerated vesting of 17,553 shares of restricted stock with a fair value of $378,267. With respect to Messrs. Vollmer and Berns, such a termination at December 31, 2010 would have resulted in the accelerated vesting of 11,703 shares of restricted stock with a fair value of $252,200. With respect to Mr. Siegel, such a termination at December 31, 2010 would have resulted in the accelerated vesting of 23,407 shares of restricted stock with a fair value of $504,421. With respect to Mr. Wexler, such a termination would have resulted in the accelerated vesting of 5,692 shares of restricted stock with a fair value of $122,663. In the event of termination of employment due to death or disability, the Named Executive Officer would vest in the portion of the performance unit award that was earned at the time of death or disability. This payment would be determined at the end of the performance period and would equal the amount that the Named Executive Officer would have received at that time, pro-rated for the amount of time from the date of grant through the date of death or disability.
 
Patterson-UTI has entered into an indemnification agreement with each of its Named Executive Officers and directors containing provisions that may require Patterson-UTI, among other things, to indemnify such executive officers and directors against liabilities that may arise by reason of their status or service as executive officers or directors (subject to certain exceptions) and to advance expenses incurred as a result of any proceeding against them as to which they could be indemnified.
 
CERTAIN TRANSACTIONS
 
In connection with the acquisition by REMY Capital Partners III, L.P. (“REMY Capital”) of an ownership interest in UTI Energy Corp. in March 1995, REMY Capital succeeded to a registration rights agreement with UTI. As the successor-in-interest to UTI, Patterson-UTI assumed this registration rights agreement pursuant to which REMY Capital has the right to require Patterson-UTI to use its reasonable efforts to register shares held by REMY Capital under the Securities Act of 1933, as amended. In the event that such rights are exercised in connection with a primary offering proposed by Patterson-UTI (or a secondary offering with which Patterson-UTI agrees to participate), REMY Capital would bear its pro rata share of the costs of the offering, other than legal, accounting and printing costs, all of which Patterson-UTI would bear. In the event that REMY Capital elects to exercise such


36


Table of Contents

rights other than in connection with an offering in which Patterson-UTI participates, REMY Capital would bear all costs of the offering. These rights continue so long as REMY Capital continues to own the Common Stock that it acquired in March 1995. As of the date of this proxy statement, REMY Capital continues to hold 1,000,000 shares of such Common Stock.
 
Mr. Siegel, Chairman of the Board of Patterson-UTI, is President and sole stockholder of REMY Investors, which is the general partner of REMY Capital. Mr. Berns, a director and Senior Vice President of Patterson-UTI, is an executive of REMY Investors.
 
In connection with Mr. Vollmer’s appointment as Chief Financial Officer, Patterson-UTI delivered a letter to Mr. Vollmer dated February 6, 2006 (the “Letter Agreement”). Pursuant to the Letter Agreement, Patterson-UTI agreed, to the extent permitted by law and provided that the applicable accounting restatement pending at that time did not result from Patterson-UTI’s material non-compliance with financial reporting requirements under the federal securities laws as a result of knowing misconduct by Mr. Vollmer:
 
  •  Patterson-UTI is not entitled to and will not make any claim against Mr. Vollmer for reimbursement of any bonus or other incentive or equity based compensation received by him or any profits realized by him from the sale of securities of Patterson-UTI, under Section 304 of the Sarbanes-Oxley Act of 2002 (“Section 304”) on account of the restatement of any financial statements of Patterson-UTI covering any accounting period ending on or prior to September 30, 2005;
 
  •  Patterson-UTI will not make any claim against Mr. Vollmer for any profits realized from the sale of securities of Patterson-UTI that were owned by him prior to his becoming Chief Financial Officer or were acquired by him on account of the exercise of options or the settling of restricted stock units that were held by him immediately prior to his becoming Chief Financial Officer, under Section 304 on account of the restatement of any financial statements of Patterson-UTI covering any period during which he was Chief Financial Officer; and
 
  •  Patterson-UTI will indemnify Mr. Vollmer against all losses in connection with his defense of any claim against him under Section 304 in contravention of the two immediately preceding bullets, to the extent he is obligated to reimburse Patterson-UTI for any bonus or other incentive or equity compensation received by him or any profits realized by him for the sale of Patterson-UTI securities.
 
Notwithstanding court decisions that Patterson-UTI’s right to make any such claims appears doubtful, Patterson-UTI entered into this agreement because of the breadth of language of Section 304 and the uncertainty as to how the statute may be interpreted by the courts in the future and the importance at the time of Mr. Vollmer’s continued service as Chief Financial Officer.
 
In 2010, Patterson-UTI provided contract drilling services to a subsidiary of a publicly traded independent natural gas and oil company of which Mr. Peak is the Chairman, Chief Executive Officer and approximately fifteen percent owner. Patterson-UTI was paid approximately $1.1 million to perform the services, which were performed in the ordinary course of their businesses and consistent with customary terms in the industry. The Board determined that this transaction was not material to either company and did not affect the director’s independence under applicable rules and regulations. The transaction was pre-approved by the Board of Directors consistent with Patterson-UTI’s related person transaction policy described below.
 
Patterson-UTI has a written policy with respect to related person transactions. In accordance with this policy, related person transactions are reviewed by the Lead Director or the chair of the Audit Committee, each of whom has full delegated authority to approve, disapprove, ratify, amend, terminate or rescind any such transaction, or direct that such transaction be submitted to the Audit Committee or the full Board of Directors for consideration. In approving or disapproving related person transactions, the relevant facts and circumstances of the related person transaction are considered, including whether such transaction is in, or not inconsistent with, the best interest of Patterson-UTI and whether, in appropriate cases, such transaction is on commercial terms at least as favorable to Patterson-UTI as would otherwise be available to or from an unrelated third party or to Patterson-UTI’s employees generally. Related person transactions generally include transactions in an amount that exceeds $50,000 between Patterson-UTI or any of its subsidiaries and an executive officer, a director (or nominee to become director), an immediate family member of any of the foregoing or any entity in which any of the foregoing has a 10% or greater


37


Table of Contents

beneficial ownership interest or in which they are an executive officer, general partner, principal or engaged in a similar position. Certain related person transactions have been pre-approved under the terms of the policy, including, subject to certain exceptions and limitations, the sale to or purchase from Patterson-UTI of goods and services by entities related to directors in the ordinary course of business that are immaterial to Patterson-UTI and with respect to which the director has no direct economic interest or decision making authority.

Delivery of Documents to Stockholders Sharing an Address
 
The SEC’s rules allow companies to send a single Notice or single copy of annual reports, proxy statements, prospectuses and other disclosure documents to two or more stockholders sharing the same address, subject to certain conditions.

5.2. Award Agreements. All Options granted pursuant to this Article shall be evidenced by a written Award Agreement in such form and containing such terms and conditions as the Committee shall determine which are not inconsistent with the provisions of the Plan. The terms of Options need not be the same with respect to each Participant. Granting of an Option pursuant to the Plan shall impose no obligation on the recipient to exercise such Option. Any individual who is granted an Option pursuant to this Article may hold more than one Option granted pursuant to the Plan at the same time. The Award Agreement also shall specify whether the Option is intended to qualify as an “incentive stock option” as defined in Section 422 of the Code.

may be provided in an Award Agreement) as to all or part of the Shares covered thereby, by the giving of written notice of exercise to the Company or its designated agent, specifying the number of Shares to be purchased, accompanied by payment of the full purchase price for the Shares being purchased. Unless otherwise provided in an Award Agreement, full payment of such purchase price shall be made at the time of exercise and shall be made (a) in cash or cash equivalents (including certified check or bank check or wire transfer of immediately available funds), (b) by tendering previously acquired Shares (either actually or by attestation, valued at their then Fair Market Value) that have been owned for a period of at least six months (or such other period to avoid accounting charges against the Company’s earnings), (c) with the consent of the Committee, by delivery of other consideration (including, where permitted by law and the Committee, other Awards) having a Fair Market Value on the exercise date equal to the total purchase price, (d) with the consent of the Committee, by withholding Shares otherwise issuable in connection with the exercise of the Option, (e) through any other method specified in an Award Agreement, or (f) any combination of any of the foregoing. The notice of exercise, accompanied by such payment, shall be delivered to the Company at its principal business office or such other office as the Committee may from time to time direct, and shall be in such form, containing such further provisions consistent with the provisions of the Plan, as the Committee may from time to time prescribe.

No adjustment shall be made for cash dividends or other rights for which the record date is prior to the date of such issuance.
 
5.6. Form of Settlement. In its sole discretion, the Committee may provide, at the time of grant, that the Shares to be issued upon an Option’s exercise shall be in the form of Restricted Stock or other similar securities, or may reserve the right so to provide after the time of grant.

The vesting schedule shall be set forth in the Award Agreement.
 
5.8. Incentive Stock Options. The Committee may grant Options intended to qualify as “incentive stock options” as defined in Section 422 of the Code, to any employee of the Company or any Subsidiary, subject to the requirements of Section 422 of the Code. Not-withstanding anything in Section 3.1 to the contrary and solely for the purposes of determining whether Shares are available for the grant of “incentive stock options” under the Plan, the maximum aggregate number of Shares with respect to which “incentive stock options” may be granted under the Plan shall be the number of Shares authorized for grant under Section 3.1.
 
5.9 No Repricing. Notwithstanding anything in the Plan to the contrary, except in connection with a corporate transaction involving the Company (including, without limitation, any stock dividend, stock split, extraordinary cash dividend, recapitalization, reorganization, merger, consolidation, split-up, spin-off, combination, or exchange of shares), the terms of outstanding Awards may not be amended to reduce the option price of outstanding Options or cancel outstanding Options in exchange for cash, other awards or Options with an option price that is less than the option price of the original Options without stockholder approval.
 
6.   STOCK APPRECIATION RIGHTS

A-6


Table of Contents

determine at any time during a specified period before the date of exercise over (ii) the grant price of the right on the date of grant, or in the case of a Tandem Stock Appreciation Right granted on the date of grant of the related Option, as specified by the Committee in its sole discretion, which, except in the case of Substitute Awards or in connection with an adjustment provided in Section 12.2, shall not be less than the Fair Market Value of one Share on such date of grant of the right or the related Option, as the case may be.
 
(b) Upon the exercise of a Stock Appreciation Right, payment shall be made in whole Shares.
 
(c) Any Tandem Stock Appreciation Right may be granted at the same time as the related Option is granted or at any time thereafter before exercise or expiration of such Option.
 
(d) Any Tandem Stock Appreciation Right related to an Option may be exercised only when the related Option would be exercisable and the Fair Market Value of the Shares subject to the related Option exceeds the option price at which Shares can be acquired pursuant to the Option. In addition, (i) if a Tandem Stock Appreciation Right exists with respect to less than the full number of Shares covered by a related Option, then an exercise or termination of such Option shall not reduce the number of Shares to which the Tandem Stock Appreciation Right applies until the number of Shares then exercisable under such Option equals the number of Shares to which the Tandem Stock Appreciation Right applies, and (ii) no Tandem Stock Appreciation Right granted under the Plan to a person then subject to Section 16 of the Exchange Act shall be exercised during the first six months of its term for cash, except as provided in Article 11.
 
(e) Any Option related to a Tandem Stock Appreciation Right shall no longer be exercisable to the extent the Tandem Stock Appreciation Right has been exercised.
 
(f) The provisions of Stock Appreciation Rights need not be the same with respect to each recipient.
 
(g) The Committee may impose such other conditions or restrictions on the terms of exercise and the exercise price of any Stock Appreciation Right, as it shall deem appropriate, including providing that the exercise price of a Tandem Stock Appreciation Right may be less than the Fair Market Value on the date of grant if the Tandem Stock Appreciation Right is added to an Option following the date of the grant of the Option. Notwithstanding the foregoing provisions of this Section 6.2(g), but subject to Section 12.2, a Freestanding Stock Appreciation Right shall generally have the same terms and conditions as Options, including (i) an exercise price not less than Fair Market Value on the date of grant, (ii) a term not greater than ten years, and (iii) not being exercisable before the expiration of one year from the date of grant to an employee of the Company or any Subsidiary (but may become exercisable pro rata over such time), except for Substitute Awards, under circumstances contemplated by Article 11 or as may be set forth in an Award Agreement with respect to (x) retirement, death or disability of a Participant or (y) special circumstances determined by the Committee, such as the achievement of performance objectives. In addition to the foregoing, but subject to Section 12.2, the base amount of any Stock Appreciation Right shall not be reduced after the date of grant.
 
(h) The Committee may impose such terms and conditions on Stock Appreciation Rights granted in conjunction with any Award (other than an Option) as the Committee shall determine in its sole discretion.
 
6.3. No Repricing. Notwithstanding anything in the Plan to the contrary, except in connection with a corporate transaction involving the Company (including, without limitation, any stock dividend, stock split, extraordinary cash dividend, recapitalization, reorganization, merger, consolidation, split-up, spin-off, combination, or exchange of shares), the terms of outstanding awards may not be amended to reduce the exercise price of outstanding Stock Appreciation Rights or cancel outstanding Stock Appreciation Rights in exchange for cash, other awards or Options or Stock Appreciation Rights with an exercise price that is less than the exercise price of the original Stock Appreciation Rights without stockholder approval.
 
7.   RESTRICTED STOCK AWARDS

7.3. Rights of Holders of Restricted Stock. Beginning on the date of grant of the Restricted Stock Award and subject to execution of the Award Agreement, the Participant shall become a shareholder of the Company with respect to all Shares subject to the Award Agreement and shall have all of the rights of a shareholder, including the right to vote such Shares and the right to receive distributions made with respect to such Shares unless otherwise provided in such Award Agreement; provided, however, that any Shares or any other property (other than cash) distributed as a dividend or otherwise with respect to any Restricted Stock as to which the restrictions have not yet lapsed shall be subject to the same restrictions as such Restricted Stock.
 
7.4. Minimum Vesting Period. Except for certain limited situations (including the death, disability or retirement of the Participant, or a Change of Control referred to in Article 11), or special circumstances determined by the Committee (such as the achievement of performance objectives) Restricted Stock Awards subject solely to continued employment restrictions of employees of the Company or any Subsidiary shall have a Restriction Period of not less than three years from date of grant (but permitting pro rata vesting over such time); provided, that the provisions of this Section shall not be applicable to any grants to new hires to replace forfeited awards from a prior employer, Substitute Awards or grants of Restricted Stock in payment of Performance Awards and other earned cash-based incentive compensation or grants to non-employee Directors. Subject to the foregoing three-year minimum vesting requirement, the Committee may, in its sole discretion and subject to the limitations imposed under Section 162(m) of the Code and the regulations thereunder in the case of a Restricted Stock Award intended to comply with the performance-based exception under Section 162(m) of the Code, waive the forfeiture period and any other conditions set forth in any Award Agreement subject to such terms and conditions as the Committee shall deem appropriate. The maximum aggregate number of Shares with respect to which Restricted Stock Awards or Other Stock Units that are subject solely to continued employment or service restrictions of Employees or directors of the Company or any Subsidiary with a Restriction Period of less than three years from date of grant (but permitting pro rata vesting over such time) shall be five percent (5%) of the number of Shares authorized for grant under Section 3.1 (as such number may be adjusted as provided in Sections 3.1 and 12.2). Any Restricted Stock Award or portion of such award that is subject to a Restriction Period of three years or more (notwithstanding the fact that a portion of such award may vest within three years of the date of grant due to pro rata vesting over the Restriction Period) or that meets the requirements of a Performance Award under Section 9 shall not be subject to the foregoing five-percent (5%) limitation.
 
7.5 Section 83(b) Election. The Committee may provide in an Award Agreement that the Award of Restricted Stock is conditioned upon the Participant making or refraining from making an election with respect to the Award under Section 83(b) of the Code. If a Participant makes an election pursuant to Section 83(b) of the Code concerning a Restricted Stock Award, the Participant shall be required to file promptly a copy of such election with the Company.
 
8.   OTHER STOCK UNIT AWARDS
 
8.1. Grants. Other Awards of units having a value equal to an identical number of Shares (“Other Stock Unit Awards”) may be granted hereunder to Participants, in addition to other Awards granted under the Plan. Other Stock Unit Awards shall also be available as a form of payment of other Awards granted under the Plan and other earned cash-based incentive compensation.
 
8.2. Award Agreements. The terms of Other Stock Unit Award granted under the Plan shall be set forth in a written Award Agreement which shall contain provisions determined by the Committee and not inconsistent with the Plan. The terms of such Awards need not be the same with respect to each Participant.

8.3. Vesting. Except for certain limited situations (including the death, disability or retirement of the Participant or a Change of Control referred to in Article 11), Other Stock Unit Awards subject solely to continued employment restrictions of employees of the Company or any Subsidiary shall be subject to restrictions imposed by the Committee for a period of not less than three years from date of grant (but permitting pro rata vesting over such time); provided, that such restrictions shall not be applicable to any Substitute Awards, grants of Other Stock Unit Awards in payment of Performance Awards pursuant to Article 9 and other earned cash-based incentive compensation, or grants of Other Stock Unit Awards on a deferred basis. The maximum aggregate number of Shares with respect to which Restricted Stock Awards or Other Stock Units that are subject solely to continued employment or service restrictions of Employees or directors of the Company or any Subsidiary with a Restriction Period of less than three years from date of grant (but permitting pro rata vesting over such time) shall be five percent (5%) of the number of Shares authorized for grant under Section 3.1 (as such number may be adjusted as provided in Sections 3.1 and 12.2). Any Other Stock Unit Award or portion of such award that is subject to a Restriction Period of three years or more (notwithstanding the fact that a portion of such award may vest within three years of the date of grant due to pro rata vesting over the Restriction Period) or that meets the requirements of a Performance Award under Article 9 shall not be subject to the foregoing five-percent (5%) limitation
 
8.4. Payment. Except as provided in Article 10 or as maybe provided in an Award Agreement, Other Stock Unit Awards may be paid in cash, Shares, other property, or any combination thereof, in the sole discretion of the Committee at the time of payment. Other Stock Unit Awards may be paid in a lump sum or in installments following the lapse of the restrictions applicable to such Awards, but, unless expressly provided in an Award Agreement, no later than 21/2 months following the end of the calendar year in which such restrictions lapse, or in accordance with procedures established by the Committee, on a deferred basis subject to the requirements of Section 409A of the Code.
 
9.   PERFORMANCE AWARDS
 
9.1. Grants. Performance Awards in the form of Performance Shares or Performance Units, as determined by the Committee in its sole discretion, may be granted hereunder to Participants, for no consideration or for such minimum consideration as may be required by applicable law, either alone or in addition to other Awards granted under the Plan. The performance goals to be achieved for each Performance Period shall be conclusively determined by the Committee and may be based upon the criteria set forth in Section 10.2.
 
9.2. Award Agreements. The terms of any Performance Award granted under the Plan shall be set forth in a written Award Agreement which shall contain provisions determined by the Committee and not inconsistent with the Plan, including whether such Awards shall have Dividend Equivalents. The terms of Performance Awards need not be the same with respect to each Participant.
 
9.3. Terms and Conditions. The performance criteria to be achieved during any Performance Period and the length of the Performance Period shall be determined by the Committee upon the grant of each Performance Award; provided, however, that a Performance Period shall not be shorter than 12 months nor longer than five years. The amount of the Award to be distributed shall be conclusively determined by the Committee.
 
9.4. Payment. Except as provided in Article 11 or as may be provided in an Award Agreement, Performance Awards will be distributed only after the end of the relevant Performance Period. Performance Awards may be paid in cash, Shares, other property, or any combination thereof, in the sole discretion of the Committee at the time of payment. Performance Awards may be paid in a lump sum or in installments, but, unless expressly provided in an Award Agreement, no later than 21/2 months following the close of the calendar year that contains the end of the Performance Period or, in accordance with procedures established by the Committee, on a deferred basis subject to the requirements of Section 409A of the Code.
 
9.5 Performance Award Dividend Equivalents. Subject to the provisions of the Plan and any Award Agreement, the Committee in its sole discretion may award currently or on a deferred basis, Dividend Equivalents with respect to the number of Shares covered by a Performance Unit or Performance Share Award, provided, that such Dividend Equivalents (if any) shall be deemed to have been reinvested in additional Shares or Units and shall provide that such Dividend Equivalents are subject to the same performance conditions as the underlying Award.

10.   CODE SECTION 162(m) PROVISIONS
 
10.1. Covered Employees. Notwithstanding any other provision of the Plan, if the Committee determines at the time a Restricted Stock Award, a Performance Award or an Other Stock Unit Award is granted to a Participant who is, or is likely to be, as of the end of the tax year in which the Company would claim a tax deduction in connection with such Award, a Covered Employee, then the Committee may provide that this Article 10 is applicable to such Award.
 
10.2. Performance Criteria. If the Committee determines that a Restricted Stock Award, a Performance Award or an Other Stock Unit Award is subject to this Article 10, the lapsing of restrictions thereon and the distribution of cash, Shares or other property pursuant thereto, as applicable, shall be subject to the achievement of one or more objective performance goals established by the Committee, which shall be based on the attainment of specified levels of one or any combination of the following: net sales; revenue growth; pre-tax income before allocation of corporate overhead and bonus; earnings per share; operating income, net income; division, group or corporate financial goals; return on stockholders’ equity; total stockholder return; return on assets; attainment of strategic and operational initiatives; appreciation in and/or maintenance of the price of the Shares or any other publicly-traded securities of the Company; market share; gross profits; earnings before taxes; earnings before interest and taxes; earnings before interest, taxes, depreciation, depletion and amortization; economic value-added models; comparisons with various stock market indices; reductions in costs; cash flow, cash flow per share; return on invested capital, cash flow return on investment; improvement in or attainment of expense levels or working capital levels; cash margins; safety records; and rig utilization and rig count growth. Such performance goals also may be based solely by reference to the Company’s performance or the performance of a Subsidiary, division, business segment or business unit of the Company, or based upon the relative performance of other companies or upon comparisons of any of the indicators of performance relative to other companies. The Committee may also exclude the impact of an event or occurrence which the Committee determines should appropriately be excluded, including (a) restructurings, discontinued operations, extraordinary items, and other unusual or non-recurring charges, (b) an event either not directly related to the operations of the Company or not within the reasonable control of the Company’s management, or (c) the cumulative effects of tax or accounting changes in accordance with generally accepted accounting principles. Such performance goals shall be set by the Committee within the time period prescribed by, and shall otherwise comply with the requirements of, Section 162(m) of the Code, and the regulations thereunder.
 
10.3. Adjustments. Notwithstanding any provision of the Plan (other than Article 11), with respect to any Restricted Stock, Performance Award or Other Stock Unit Award that is subject to this Section 10, the Committee may adjust downwards, but not upwards, the amount payable pursuant to such Award, and the Committee may not waive the achievement of the applicable performance goals, except in the case of the death or disability of the Participant or as otherwise determined by the Committee in special circumstances.
 
10.4. Restrictions. The Committee shall have the power to impose such other restrictions on Awards subject to this Article as it may deem necessary or appropriate to ensure that such Awards satisfy all requirements for “performance-based compensation” within the meaning of Section 162(m) of the Code.
 
10.5. Limitations on Grants to Individual Participant. Subject to adjustment as provided in Section 12.2, no Participant may be granted (i) Options or Stock Appreciation Rights during any 12-month period with respect to more than 1,000,000 Shares or (ii) Restricted Stock, Performance Awards and/or Other Stock Unit Awards that are denominated in Shares in any 12-month period with respect to more than 500,000 Shares (the “Limitations”). In addition to the foregoing, the maximum dollar value payable to any Participant in any 12-month period with respect to Performance Awards is $5,000,000. If an Award is cancelled, the cancelled Award shall continue to be counted toward the applicable Limitations.
 
11.   CHANGE OF CONTROL PROVISIONS
 
Impact of Change of Control. The terms of any Award may provide in the Award Agreement evidencing the Award that, upon a “Change of Control” of the Company, (a) Options and Stock Appreciation Rights outstanding as of the date of the Change of Control immediately vest and become fully exercisable, (b) that Options and Stock Appreciation Rights outstanding as of the date of the Change of Control may be cancelled and terminated without

Table of Contents

payment therefore if the Fair Market Value of one Share as of the date of the Change of Control is less than the per Share Option exercise price or Stock Appreciation Right grant price, (c) restrictions and deferral limitations on Restricted Stock lapse and the Restricted Stock become free of all restrictions and limitations and become fully vested, (d) all Performance Awards shall be considered to be earned and payable (either in full or pro rata based on the portion of Performance Period completed as of the date of the Change of Control), and any deferral or other restriction shall lapse and such Performance Awards shall be immediately settled or distributed to the extent permitted under Section 409A of the Code, (e) the restrictions and deferral limitations and other conditions applicable to any Other Stock Unit Awards or any other Awards shall lapse, and such Other Stock Unit Awards or such other Awards shall become free of all restrictions, limitations or conditions and become fully vested and transferable to the full extent of the original grant to the extent permitted under Section 409A of the Code, and (f) such other additional benefits as the Committee deems appropriate shall apply, subject in each case to any terms and conditions contained in the Award Agreement evidencing such Award. Effective with respect to Awards granted prior to April 26, 2010, for purposes of the Plan, a “Change of Control” shall mean an event described in an Award Agreement evidencing the Award or such other event as determined in the sole discretion of the Board. Notwithstanding any other provision of the Plan, the Committee, in its discretion, may determine that, upon the occurrence of a Change of Control of the Company, each Option and Stock Appreciation Right outstanding shall terminate within a specified number of days after notice to the Participant, and/or that each Participant shall receive, with respect to each Share subject to such Option or Stock Appreciation Right, an amount equal to the excess of the Fair Market Value of such Share immediately prior to the occurrence of such Change of Control over the exercise price per share of such Option and/or Stock Appreciation Right; such amount to be payable in cash, in one or more kinds of stock or property (including the stock or property, if any, payable in the transaction) or in a combination thereof, as the Committee, in its discretion, shall determine.
 
12.   GENERALLY APPLICABLE PROVISIONS
 
12.1. Amendment and Termination of the Plan. The Board may, from time to time, alter, amend, suspend or terminate the Plan as it shall deem advisable, subject to any requirement for stockholder approval imposed by applicable law, including the rules and regulations of the NASDAQ Stock Market (or any other principal national securities exchange on which the Company is listed) provided that the Board may not amend the Plan in any manner that would result in noncompliance with Rule 16b-3 of the Exchange Act; and further provided that the Board may not, without the approval of the Company’s stockholders, amend the Plan to (a) increase the number of Shares that may be the subject of Awards under the Plan (except for adjustments pursuant to Section 12.2), (b) expand the types of awards available under the Plan, (c) materially expand the class of persons eligible to participate in the Plan, (d) amend any provision of Section 5.3, (e) increase the maximum permissible term of any Option specified by Section 5.4, or (f) amend any provision of Section 10.4. In addition, no amendments to, or termination of, the Plan shall in any way impair the rights of a Participant under any Award previously granted without such Participant’s consent.
 
12.2. Adjustments. In the event of any merger, reorganization, consolidation, recapitalization, dividend or distribution (whether in cash, shares or other property, other than a regular cash dividend), stock split, reverse stock split, spin-off or similar transaction or other change in corporate structure affecting the Shares or the value thereof, such adjustments and other substitutions shall be made to the Plan and to Awards as the Committee, in its sole discretion, deems equitable or appropriate, including such adjustments in the aggregate number, class and kind of securities that may be delivered under the Plan and, in the aggregate or to any one Participant, in the number, class, kind and option or exercise price of securities subject to outstanding Awards granted under the Plan (including, if the Committee deems appropriate, the substitution of similar options to purchase the shares of, or other awards denominated in the shares of, another company) as the Committee may determine to be appropriate in its sole discretion; provided, however, that the number of Shares subject to any Award shall always be a whole number.
 
12.3. Transferability of Awards. Except as provided below, no Award and no Shares subject to Awards described in Article 8 that have not been issued or as to which any applicable restriction, performance or deferral period has not lapsed, may be sold, assigned, transferred, pledged or otherwise encumbered, other than by will or the laws of descent and distribution, and such Award may be exercised during the life of the Participant only by the Participant or the Participant’s guardian or legal representative. Notwithstanding the foregoing, a Participant may


A-11


Table of Contents

assign or transfer an Award with the consent of the Committee (i) for charitable donations; (ii) to the Participant’s spouse, children or grandchildren (including any adopted and stepchildren and grandchildren), or (iii) a trust for the benefit of one or more of the Participants or the persons referred to in clause (ii) (each transferee thereof, a “Permitted Assignee”); provided that such Permitted Assignee shall be bound by and subject to all of the terms and conditions of the Plan and the Award Agreement relating to the transferred Award and shall execute an agreement satisfactory to the Company evidencing such obligations; and provided further that such Participant shall remain bound by the terms and conditions of the Plan. The Company shall cooperate with any Permitted Assignee and the Company’s transfer agent in effectuating any transfer permitted under this Section. Notwithstanding the foregoing, no Incentive Stock Option granted under the Plan may be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated, other than by will or by the laws of descent and distribution. Further, all Incentive Stock Options granted to a Participant under this Plan shall be exercisable during his or her lifetime only by such Participant.
 
12.4. Termination of Employment. The Committee shall determine and set forth in each Award Agreement whether any Awards granted in such Award Agreement will continue to be exercisable, and the terms of such exercise, on and after the date that a Participant ceases to be employed by or to provide services to the Company or any Subsidiary (including as a Director), whether by reason of death, disability, voluntary or involuntary termination of employment or services, or otherwise. The date of termination of a Participant’s employment or services will be determined by the Committee, which determination will be final.
 
12.5. Deferral. The Committee shall be authorized to establish procedures pursuant to which the payment of any Award may be deferred. Such deferrals shall be administered in a manner that is intended to comply with Section 409A of the Code and shall be construed and interpreted in accordance with such intent.
 
12.6 Dividend Equivalents. Subject to the provisions of the Plan and any Award Agreement, the recipient of an Award (including any deferred Award) may, if so determined by the Committee, be entitled to receive, currently or on a deferred basis, cash, stock or other property dividends, or cash payments in amounts equivalent to cash, stock or other property dividends on Shares (“Dividend Equivalents”) with respect to the number of Shares covered by the Award, as determined by the Committee, in its sole discretion. The Committee may provide that such amounts and Dividend Equivalents (if any) shall be deemed to have been reinvested in additional Shares or otherwise reinvested and may provide that such amounts and Dividend Equivalents are subject to the same vesting conditions as the underlying Award; provided, however, that with respect to Dividend Equivalents (if any) awarded in connection with a Performance Unit Award or Performance Share Award, such Dividend Equivalents (if any) shall be deemed to have been reinvested in additional Shares or Units and shall provide that such Dividend Equivalents are subject to the same performance conditions as the underlying Award.
 
13.   MISCELLANEOUS
 
13.1. Tax Withholding. The Company shall have the right to make all payments or distributions pursuant to the Plan to a Participant (or a Permitted Assignee thereof) (any such person, a “Payee”) net of any applicable federal, state and local taxes required to be paid or withheld as a result of (a) the grant of any Award, (b) the exercise of an Option or Stock Appreciation Right, (c) the delivery of Shares or cash, (d) the lapse of any restrictions in connection with any Award or (e) any other event occurring pursuant to the Plan. The Company or any Subsidiary shall have the right to withhold from wages or other amounts otherwise payable to such Payee such minimum statutory withholding taxes as may be required by law, or to otherwise require the Payee to pay such withholding taxes. If the Payee shall fail to make such tax payments as are required, the Company or its Subsidiaries shall, to the extent permitted by law, have the right to deduct any such taxes from any payment of any kind otherwise due to such Payee or to take such other action as may be necessary to satisfy such withholding obligations. The Committee shall be authorized to establish procedures for election by Participants to satisfy such obligation for the payment of such taxes by tendering previously acquired Shares (either actually or by attestation, valued at their then Fair Market Value) that have been owned for a period of at least six months (or such other period to avoid accounting charges against the Company’s earnings), or by directing the Company to retain Shares (up to the Participant’s minimum required tax withholding rate or such other rate that will not trigger a negative accounting impact) otherwise deliverable in connection with the Award.

13.2. Right of Discharge Reserved; Claims to Awards. Nothing in the Plan nor the grant of an Award hereunder shall confer upon any Employee or Director the right to continue in the employment or service of the Company or any Subsidiary or affect any right that the Company or any Subsidiary may have to terminate the employment or service of (or to demote or to exclude from future Awards under the Plan) any such Employee or Director at any time for any reason. Except as specifically provided by the Committee, the Company shall not be liable for the loss of existing or potential profit from an Award granted in the event of termination of an employment or other relationship. No Employee or Participant shall have any claim to be granted any Award under the Plan, and there is no obligation for uniformity of treatment of Employees or Participants under the Plan.
 
13.3. Prospective Recipient. The prospective recipient of any Award under the Plan shall not, with respect to such Award, be deemed to have become a Participant, or to have any rights with respect to such Award, until and unless such recipient shall have executed an agreement or other instrument evidencing the Award and delivered a copy thereof to the Company, and otherwise complied with the then applicable terms and conditions.
 
13.4. Cancellation of Award. Notwithstanding anything to the contrary contained herein, all outstanding Awards granted to any Participant shall be canceled if the Participant, without the consent of the Company, while employed by the Company or any Subsidiary or after termination of such employment or service, establishes a relationship with a competitor of the Company or any Subsidiary or engages in activity that is in conflict with or adverse to the interest of the Company or any Subsidiary, as determined by the Committee in its sole discretion.
 
13.5. Stop Transfer Orders. All certificates for Shares delivered under the Plan pursuant to any Award shall be subject to such stop-transfer orders and other restrictions as the Committee may deem advisable under the rules, regulations and other requirements of the Securities and Exchange Commission, any stock exchange upon which the Shares are then listed, and any applicable federal or state securities law, and the Committee may cause a legend or legends to be put on any such certificates to make appropriate reference to such restrictions.
 
13.6. Nature of Payments. All Awards made pursuant to the Plan are in consideration of services performed or to be performed for the Company or any Subsidiary, division or business unit of the Company. Any income or gain realized pursuant to Awards under the Plan and any Stock Appreciation Rights constitute a special incentive payment to the Participant and shall not be taken into account, to the extent permissible under applicable law, as compensation for purposes of any of the employee benefit plans of the Company or any Subsidiary except as may be determined by the Committee or by the Board or board of directors of the applicable Subsidiary.
 
13.7. Other Plans. Nothing contained in the Plan shall prevent the Board from adopting other or additional compensation arrangements, subject to stockholder approval if such approval is required; and such arrangements may be either generally applicable or applicable only in specific cases.
 
13.8. Severability. If any provision of the Plan shall be held unlawful or otherwise invalid or unenforceable in whole or in part by a court of competent jurisdiction, such provision shall (a) be deemed limited to the extent that such court of competent jurisdiction deems it lawful, valid and/or enforceable and as so limited shall remain in full force and effect, and (b) not affect any other provision of the Plan or part thereof, each of which shall remain in full force and effect. If the making of any payment or the provision of any other benefit required under the Plan shall be held unlawful or otherwise invalid or unenforceable by a court of competent jurisdiction, such unlawfulness, invalidity or unenforceability shall not prevent any other payment or benefit from being made or provided under the Plan, and if the making of any payment in full or the provision of any other benefit required under the Plan in full would be unlawful or otherwise invalid or unenforceable, then such unlawfulness, invalidity or unenforceability shall not prevent such payment or benefit from being made or provided in part, to the extent that it would not be unlawful, invalid or unenforceable, and the maximum payment or benefit that would not be unlawful, invalid or unenforceable shall be made or provided under the Plan.
 
13.9. Construction. As used in the Plan, the words “include” and “including,” and variations thereof, shall not be deemed to be terms of limitation, but rather shall be deemed to be followed by the words “without limitation.”
 
13.10. Unfunded Status of the Plan. The Plan is intended to constitute an “unfunded” plan for incentive and deferred compensation. With respect to any payments not yet made to a Participant by the Company, nothing contained herein shall give any such Participant any rights that are greater than those of a general creditor of the Company. In its sole discretion, the Committee may authorize the creation of trusts or other arrangements to meet


A-13


Table of Contents

the obligations created under the Plan to deliver the Shares or payments in lieu of or with respect to Awards hereunder; provided, however, that the existence of such trusts or other arrangements is consistent with the unfunded status of the Plan.
 
13.11. Governing Law. The Plan and all determinations made and actions taken thereunder, to the extent not otherwise governed by the Code or the laws of the United States, shall be governed by the laws of the State of Delaware, without reference to principles of conflict of laws, and construed accordingly.
 
13.12. Effective Date of Plan; Termination of Plan. The Plan shall be effective on the date of the approval of the Plan by the holders of the shares entitled to vote at a duly constituted meeting of the stockholders of the Company. The Plan shall be null and void and of no effect if the foregoing condition is not fulfilled and in such event each Award shall, notwithstanding any of the preceding provisions of the Plan, be null and void and of no effect. Awards may be granted under the Plan at any time and from time to time on or prior to the tenth anniversary of the effective date of the Plan, on which date the Plan will expire except as to Awards then outstanding under the Plan. Such outstanding Awards shall remain in effect until they have been exercised or terminated, or have expired.
 
13.13. Foreign Employees. Awards may be granted to Participants who are foreign nationals or employed outside the United States, or both, on such terms and conditions different from those applicable to Awards to Employees employed in the United States as may, in the judgment of the Committee, be necessary or desirable in order to recognize differences in local law or tax policy. The Committee also may impose conditions on the exercise or vesting of Awards in order to minimize the Company’s obligation with respect to tax equalization for Employees on assignments outside their home country.
 
13.14. Compliance with Section 409A of the Code. This Plan is intended to comply and shall be administered in a manner that is intended to comply with Section 409A of the Code and shall be construed and interpreted in accordance with such intent. To the extent that an Award or the payment, settlement or deferral thereof is subject to Section 409A of the Code, the Award shall be granted, paid, settled or deferred in a manner that will comply with Section 409A of the Code, including regulations or other guidance issued with respect thereto, except as otherwise determined by the Committee. Any provision of this Plan that would cause the grant of an Award or the payment, settlement or deferral thereof to fail to satisfy Section 409A of the Code shall be amended to comply with Section 409A of the Code on a timely basis, which may be made on a retroactive basis, in accordance with regulations and other guidance issued under Section 409A of the Code.
 
13.15. Captions. The captions in the Plan are for convenience of reference only, and are not intended to narrow, limit or affect the substance or interpretation of the provisions contained herein.
 
13.16. Notification of Disqualifying Disposition. If any Participant shall make any disposition of Shares issued pursuant to the exercise of an incentive stock option under the circumstances described in Section 421(b) of the Code (relating to certain disqualifying dispositions), such Participant shall notify the Company of such disposition within ten (10) days thereof.
 
13.17. Sarbanes Oxley Act. If the Company is required to prepare an accounting restatement due to the material noncompliance of the Company, as a result of misconduct, with any financial reporting requirement under the securities laws, or if the Participant is one of the persons subject to automatic forfeiture under Section 304 of the Sarbanes-Oxley Act of 2002, the Participant shall reimburse the Company the amount of any payment in settlement of an Award earned or accrued during the twelve-month period following the first public issuance or filing with the United States Securities and Exchange Commission (whichever just occurred) of the financial document embodying such financial reporting requirement.
 
13.18. Retirement and Welfare Plans. Neither Awards made under the Plan nor Shares or cash paid pursuant to such Awards, may be included as “compensation” for purposes of computing the benefits payable to any Participant under the Company’s or any Subsidiary’s retirement plans (both qualified and non-qualified) or welfare benefit plans unless such other plan expressly provides that such compensation shall be taken into account in computing a participant’s benefit.
 
13.19. Indemnification. Each person who is or shall have been a member of the Board, or a Committee appointed by the Board, or an officer of the Company to whom authority was delegated in accordance with


A-14


Table of Contents

Section 4.2 shall be indemnified and held harmless by the Company against and from any loss, cost, liability, or expense that may be imposed upon or reasonably incurred by him or her in connection with or resulting from any claim, action, suit, or proceeding to which he or she may be a party or in which he or she may be involved by reason of any action taken or failure to act under the Plan and against and from any and all amounts paid by him or her in settlement thereof, with the Company’s approval, or paid by him or her in satisfaction of any judgment in any such action, suit, or proceeding against him or her, provided he or she shall give the Company an opportunity, at its own expense, to handle and defend the same before he or she undertakes to handle and defend it on his or her own behalf, unless such loss, cost, liability, or expense is a result of his or her own willful misconduct or except as expressly provided by statute. The foregoing right of indemnification shall not be exclusive of any other rights of indemnification to which such persons may be entitled under the Company’s Certificate of Incorporation of Bylaws, as a matter of law, or otherwise, or any power that the Company may have to indemnify them or hold them harmless.
