By granting the Proxy, you authorize the persons named on the Proxy to represent you and vote your shares at the Annual Meeting. Those persons will also be authorized to vote your shares to adjourn the Annual Meeting from time to time and to vote your shares at any adjournments or postponements of the Annual Meeting. You may grant your Proxy by signing, dating and returning the enclosed paper proxy card. Instead of returning the paper proxy card, you may complete a proxy card electronically through the Internet by accessing the website of the Company's transfer agent at www.continentalstock.com. You will need the control numbers that are printed on your personalized paper proxy card. See "Internet Voting." If you attend the Annual Meeting, you may vote in person. If you are not present at the Annual Meeting, your shares may be voted only by a person to whom you have given a proper proxy, such as the accompanying Proxy or the Internet Proxy. You may revoke the Proxy in writing at any time before it is exercised at the Annual Meeting by delivering to the Secretary of the Company a written notice of the revocation, or by signing and delivering to the Secretary of the Company a proxy with a later date or by submitting your vote electronically through the Internet with a later date. Your attendance at the Annual Meeting will not revoke the Proxy unless you give written notice of revocation to the Secretary of the Company before the Proxy is exercised or unless you vote your shares in person at the Annual Meeting. This Proxy Statement and the accompanying Notice of Annual Meeting and Proxy are first being sent or given to stockholders of the Company on or about April 9, 2003. QUORUM AND VOTING Voting Stock. The Company has one outstanding class of securities that entitle holders to vote generally at meetings of the Company's stockholders: common stock, par value $.01 per share. Each share of common stock outstanding on the record date is entitled to one vote. Record Date. The record date for stockholders entitled to notice of and to vote at the Annual Meeting is the close of business on March 19, 2003. At the record date, 117,610,782 shares of common stock were outstanding and entitled to be voted at the Annual Meeting. Quorum and Adjournments. The presence, in person or by proxy, of the holders of a majority of the votes eligible to be cast at the Annual Meeting is necessary to constitute a quorum at the Annual Meeting. If a quorum is not present, the stockholders entitled to vote who are present in person or by proxy at the Annual Meeting have the power to adjourn the Annual Meeting from time to time, without notice other than an announcement at the Annual Meeting, until a quorum is present. At any adjourned Annual Meeting at which a quorum is present, any business may be transacted that might have been transacted at the Annual Meeting as originally notified. Vote Required. Directors will be elected by a plurality of the votes present and entitled to be voted at the Annual Meeting. Ratification of the selection of the Company's auditors will require the affirmative vote of the holders of a majority of the shares present and entitled to be voted at the 3 Annual Meeting. An automated system that the Company's transfer agent administers will tabulate the votes. Brokers who hold shares in street name for customers are required to vote shares in accordance with instructions received from the beneficial owners. Brokers are permitted to vote on discretionary items if they have not received instructions from the beneficial owners, but they are not permitted to vote (a "broker non-vote") on non-discretionary items absent instructions from the beneficial owner. Abstentions and broker non-votes will count in determining whether a quorum is present at the Annual Meeting. Both abstentions and broker non-votes will not have any effect on the outcome of voting on director elections. For purposes of voting on the ratification of the selection of auditors, abstentions will be included in the number of shares voting and will have the effect of a vote against the proposal, and broker non-votes will not be included in the number of shares voting and therefore will have no effect on the outcome of the voting. Default Voting. A Proxy that is properly completed and returned will be voted at the Annual Meeting in accordance with the instructions on the Proxy. If you properly complete and return a Proxy, but do not indicate any contrary voting instructions, your shares will be voted as follows: o FOR the election of the three persons named in this Proxy Statement as the Board of Directors' nominees for election to the Board of Directors. o FOR the ratification of the selection of Ernst & Young LLP as the Company's auditors. If any other business properly comes before the stockholders for a vote at the meeting, your shares will be voted in accordance with the discretion of the holders of the Proxy. The Board of Directors knows of no matters, other than those previously stated, to be presented for consideration at the Annual Meeting. ITEM ONE ELECTION OF DIRECTORS The Board of Directors has nominated the following individuals for election as Class III directors of the Company with their terms to expire at the annual meeting of stockholders in 2006 when their successors are elected and qualified: Jerry P. Jones Charles E. Ramsey, Jr. Robert A. Solberg Messrs. Jones, Ramsey and Solberg are currently serving as directors of the Company. Their biographical information is contained in "Directors and Executive Officers." The Board of Directors has no reason to believe that any of its nominees will be unable or unwilling to serve if elected. If a nominee becomes unable or unwilling to accept nomination or election, either the number of the Company's directors will be reduced or the persons acting under the Proxy will vote for the election of a substitute nominee that the Board of Directors recommends. The Board of Directors recommends that stockholders vote FOR the election of each of the nominees.

In connection with the audits of the Company's annual financial statements for 2002, 2001 and 2000, there were no disagreements with Ernst & Young LLP on any matters of accounting principles or practices, financial statement disclosure, or auditing scope or procedures which, if not resolved to the satisfaction of such independent accountants, would have caused such independent accountants to make reference to the matter in their audit report.

MANAGEMENT COMPENSATION Compensation of Directors Each non-employee director receives an annual base retainer fee of $40,000 and an annual fee of $10,000 for service on one or more committees. Audit committee members receive an additional $7,500 annual fee and Mr. Baroffio in his role as geosciences advisor to the Board of Directors receives an additional $7,500 annual fee. The chairman of the audit committee also receives a $5,000 annual fee and other committee chairmen receive a $2,500 annual fee. Each non-employee director is also reimbursed for travel expenses to attend meetings of the Board of Directors or its committees. No additional fees are paid for attendance at Board of Directors or committee meetings. The Company's Chief Executive Officer does not receive additional compensation for serving on the Board of Directors. Under the Company's Long-Term Incentive Plan, non-employee directors are eligible to receive their fees in the form of non-qualified stock options, stock appreciation rights, restricted stock, or performance units. The Company can use these awards instead of cash to pay its non-employee directors all or part of their annual fees. The Board of Directors determines the form (or combination of forms) of consideration each year, based on the economic and other circumstances at the time and based on its view of which awards will best align the interests of the stockholders and the directors. For the year following the Company's 2002 annual stockholders' meeting, the Board of Directors were given a choice to be compensated in (a) 100 percent cash, (b) 100 percent stock options, (c) 100 percent restricted stock, or (d) a combination of 50/50 of any two, in payment of the non-employee directors' annual fees. Messrs. Baroffio, Jones, Ramsey and Solberg and Mrs. Lawson elected 100 percent cash compensation; Mr. Gardner elected to receive 100 percent of his compensation in stock options; Mr. Buchanan elected to receive 100 percent of his compensation in restricted stock; and Mr. Houghton elected to receive 50 percent of his compensation in cash and 50 percent in restricted stock. The number of shares granted to non-employee directors electing stock options was determined by dividing the directors' annual fees by the value of an option for one share on May 13, 2002 (the last closing sale price before the date of the grant). The options have a fair-market value exercise price, and the value of each option was calculated using the Black-Scholes method based on assumptions provided by the Company's executive compensation consulting firm. These options vested 25 percent each quarter with the first vesting date on August 14, 2002. The number of shares granted to non-employee directors electing restricted stock was determined by dividing the director's fees elected to be paid by restricted stock by the closing price of one share of the Company stock on May 13, 2002 (the last closing sale price before the date of the grant). The restricted stock grants vested 25 percent each quarter with the first vesting date on August 14, 2002. On May 14, 2002, Mr. Gardner received a grant of 5,017 stock options to compensate him for his annual fees (each stock option granted has an exercise price of $24.60). Mr. Buchanan received a restricted stock grant of 2,032 shares to compensate him for 100 percent of his annual fees, and Mr. Houghton received a restricted stock grant of 1,270 shares to compensate him for 50 percent of his annual fees. Each non-employee director, upon commencement of initial service as a director, receives $125,000 of restricted stock. The price used to calculate the number of shares to be granted is based on the closing stock price on the day prior to the day the director is elected to serve on the Board of Directors. The shares granted are subject to vesting and transfer restrictions that lapse with respect to one-third of the shares each year following the grant over a three year period. The vesting of ownership and the lapse of transfer restrictions may be accelerated in the event of the death, disability or retirement of the director or a change in control of the Company. Each recipient is required to make an election under the Internal Revenue Code to include the value of the restricted stock in the recipient's income in the year of grant, and the Company agrees to provide a cash award to the non-employee director in an amount 9 sufficient to pay the federal income taxes due with respect to the grant and such cash payment. On May 14, 2002, Mrs. Lawson and Messrs. Buchanan and Solberg, as newly elected non-employee directors, each received a grant of 5,081 shares of Company common stock (which number was calculated by dividing $125,000 by $24.60, the closing stock price on May 13, 2002) and a cash payment of $83,500 to pay the federal income taxes on the grant and the cash payment. For the year following the Company's 2003 annual scheduled meeting, directors can again elect to receive their annual fees 100 percent in cash, stock options or restricted stock or 50 percent each in any two of those three forms of compensation. Compensation of Executive Officers The compensation paid to the Company's executive officers generally consists of base salaries, annual bonuses, awards under the Long-Term Incentive Plan, contributions to the Company's 401(k) retirement plan, contributions to the Company's deferred compensation retirement plan, and miscellaneous perquisites.

(b) This column represents miscellaneous perquisites. (c) The value of the restricted stock reported in this column was determined using the August 12, 2002 grant date closing price of $24.54 per share for the Company's common stock as reported by the New York Stock Exchange. The restricted stock grant replaced a like value of stock options that would have been issued over the next three years and includes vesting restrictions that lapse on August 12, 2005. The restricted stock is entitled to receive dividends, if any, paid on the Company's common stock. Aggregate restricted Company common stockholdings as of December 31, 2002 and the corresponding value based on the closing price of the common stock as reported on the New York Stock Exchange on December 31, 2002 are: Mr. Sheffield, 72,000 shares, $1,818,000; Messrs. Dove, Fagerstone, Kellum and Withrow, 24,000 shares each, $606,000 each. 10 (d) For 2002 this column includes (i) contributions to qualified retirement plans for Mr. Sheffield of $19,457, and for Messrs. Dove, Fagerstone, Kellum and Withrow of $20,031 each; (ii) contributions to the Company's non-qualified deferred compensation retirement plan for Mr. Sheffield of $70,000 and Messrs. Dove, Fagerstone, Kellum and Withrow of $31,500 each; (iii) a $4,042 premium with respect to a term life insurance policy for the benefit of Mr. Sheffield; and (iv) reimbursement for financial counseling services for Messrs. Sheffield and Withrow of $3,340 and $565, respectively. Long-Term Incentive Plan. The Long-Term Incentive Plan (the "Plan") provides for employee and non-employee director grants in the form of stock options, stock appreciation rights, restricted stock, and performance units payable in stock or cash. The maximum number of shares of common stock that may be issued under the Plan is equal to 10 percent of the total number of shares of common stock equivalents outstanding from time to time minus the total number of shares of stock subject to outstanding grants on the date of calculation under any other stock-based plan for employees or directors of the Company. The Plan had 4,306,586 shares available for additional awards at December 31, 2002. No performance units or stock appreciation rights have been awarded under the Plan. The following table sets forth information about stock option grants made during 2002 to the named executive officers.

The Compensation Committee retains discretion, subject to Plan limits, to modify the terms of the options. In the event of a change in control of the Company as defined in the Plan, the options will immediately become fully vested and exercisable in full. (b) These options were granted on August 12, 2002, vest at the rate of one-third each year commencing on the first anniversary of the grant date, and have terms of five years from the dates of vesting. The Compensation Committee retains discretion, subject to Plan limits, to modify the terms of the options. In the event of a change in control of the Company as defined in the Plan, the options will immediately become fully vested and exercisable in full. (c) The exercise price per share is equal to the closing price of the Company's common stock on the New York Stock Exchange composite tape on the day before the date of grant. (d) The estimated grant date value of options described in footnotes (a) and (b) were determined using the Black-Scholes model. The material assumptions and adjustments incorporated in the Black-Scholes model in estimating the value of the options included the following: o Annual interest rates of 2.76 percent for footnote (a) and 2.92 percent for footnote (b), which represent the interest rates on U.S. Treasury securities with maturity dates corresponding to the expected option term. 11 o Volatility of 50 percent for footnote (a) and 39 percent for footnote (b) and calculated using the lesser of (1) daily stock prices for the 120-day period prior to the grant date or (2) 50 percent. No other adjustments were made to the model for non-transferability or risk of forfeiture. The ultimate values of the options will depend on the future market price of the Company's common stock, which cannot be forecast with reasonable accuracy. The actual value, if any, an optionee will realize upon exercise of an option will depend on the excess of the market value of the Company's common stock over the exercise price on the date the option is exercised. The following table sets forth, for each named executive officer, information concerning the exercise of stock options during 2002, and the value of unexercised stock options as of December 31, 2002. AGGREGATED OPTION EXERCISES IN LAST FISCAL YEAR AND FISCAL YEAR END OPTION VALUES Number of Securities Value of Unexercised Number of Underlying Unexercised In-the-Money Shares Options at Fiscal Year End Options at Fiscal Year End (a) Acquired on Value --------------------------- ---------------------------- Exercise Realized Exercisable Unexercisable Exercisable Unexercisable ----------- -------- ----------- ------------- ----------- ------------- Scott Sheffield....... - $ - 213,500 262,000 $1,707,204 $1,603,270 Timothy Dove.......... 11,667 $146,633 116,500 100,665 $ 693,886 $ 697,683 Dennis Fagerstone..... - $ - 208,689 100,665 $ 788,518 $ 697,683 Danny Kellum.......... 52,334 $767,501 52,667 100,665 $ 239,450 $ 697,683 Mark Withrow.......... 15,835 $160,531 124,333 100,665 $ 870,091 $ 697,683(a) Amounts were calculated by multiplying the number of unexercised options by $25.25, which was the closing price of the Company's common stock on December 31, 2002, and subtracting the aggregate exercise price, which was determined by multiplying the unexercised option by their respective exercise prices and summing the result. Retirement Plan. The Company does not provide a defined benefit retirement plan or a restoration plan. Hewitt Associates, the Company's compensation consultant, advised the Company that it was not providing competitive retirement benefits for its officers by offering only a 401(k) plan. To maintain a competitive position, the Company also provides a non-qualified deferred compensation retirement plan for officers of the Company. Each participant is allowed to contribute up to 25 percent of base salary. The Company provides a matching contribution of 100 percent of the participant's contribution limited to the first 10 percent of the officer's base salary. The Company's matching contribution vests immediately. Severance Agreements. The Company has entered into severance agreements with its officers. Salaries and bonuses are set by the Compensation Committee independent of these agreements, and the Compensation Committee can increase or reduce base salaries at its discretion. Either the Company or the officer may terminate the officer's employment under the severance agreement at any time. The Company must pay the officer an amount equal to one year's base salary if the officer's employment is terminated because of death, disability, or normal retirement. The Company must pay the officer an amount equal to one year's base salary and continue health insurance for the officer's family for one year if the Company terminates the officer's employment without cause or if the officer terminates employment for good reason, which is when reductions in the officer's base annual salary exceed specified limits or when the officer's responsibilities have been significantly reduced. If within one year after a change in control of the Company, the Company terminates the officer without cause, or if the officer terminates employment for good reason, the Company must pay the officer an amount equal to 2.99 times the sum of the officer's base salary plus target bonus for the year and continue health insurance for the officer's family for three years. If the officer terminates employment with the Company without reason between six months and one year after a change in control, or at any time within one year after a change in control if the officer is required to move, then the Company must pay the officer one year's base salary and continue health insurance for the officer's family for one year. Officers are also entitled to additional payments for certain tax liabilities that may apply to severance payments following a change in control. 12 Indemnification Agreements. The Company has entered into indemnification agreements with each of its directors and officers, including the named executive officers. Those agreements require the Company to indemnify the directors and officers to the fullest extent permitted by the Delaware General Corporation Law and to advance expenses in connection with certain claims against directors and officers. The Company expects to enter into similar agreements with persons selected to be directors and officers in the future. Each indemnification agreement also provides that, upon a potential change in control of the Company and if the indemnified director or officer so requests, the Company will create a trust for the benefit of the indemnified director or officer in an amount sufficient to satisfy payment of all liabilities and suits against which the Company has indemnified the director or officer.

The number of remaining securities available for future issuance under the Company's Employee Stock Purchase Plan is based on the original authorized issuance of 750,000 shares less 127,801 cumulative shares issued through December 31, 2002. See Note G of Notes to Consolidated Financial Statements included in "Item 8. Financial Statements and Supplementary Data" in the Company's Annual Report on Form 10-K for the year ended December 31, 2002 for additional information about the Company's equity compensation plans. The Company has no equity compensation plans that have not been approved by security holders. COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION During fiscal year 2002, no member of the Compensation Committee also served as an executive officer of the Company. During fiscal year 2002, there were no Compensation Committee interlocks with other companies. 13 COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION The Compensation Committee of the Board of Directors submits the following report with respect to the executive compensation program of the Company. Compensation Principles and Philosophy The overriding responsibility of the committee is to maintain the Company's executive compensation program so that it attracts and retains a capable and highly motivated senior management team and aligns the compensation of the Company's executives with the Company's strategic business plan to increase stockholder value. During 2002 the committee retained an executive compensation consulting firm ("Hewitt Associates") to assist and advise it in its efforts to establish and administer fair and competitive compensation and incentive policies. These policies emphasize variable compensation, structure the annual bonus and long-term incentive awards to be a significant portion of an executive's total compensation and result in total compensation that is reflective of Company performance. A combination of stock option awards and restricted stock will be emphasized as part of each executive's compensation package to align stockholder and executive interests. The committee has adopted a policy of not repricing stock options and incorporated that policy into the Company's long-term incentive plan. Other critical elements of the Company's compensation and incentive policies provide for: o Base salaries at or slightly above median levels compared to industry survey information and peer group proxy analysis o Annual target bonus levels slightly above median with payouts that are based on both individual and Company performance o Long-term incentive award levels that are above median o Significant stock ownership by directors and the Chief Executive Officer. To support the commitment to significant stock ownership, the Company's current common stock ownership guidelines are as follows: o Non-employee directors' stock value equal to at least three times each director's annual base retainer fee o Chairman of the Board and Chief Executive Officer stock value equal to at least five times his annual base salary. In determining compliance with these guidelines, the committee considers its expectations of the long-term value of the Company's common stock and the current trading levels. Mr. Sheffield and all directors are in compliance with the ownership guidelines. The Omnibus Budget Reconciliation Act of 1993 ("OBRA93") placed restrictions on the deductibility of executive compensation paid by public companies. Under the restrictions, the Company is not able to deduct compensation paid to any of the named executive officers in excess of $1,000,000 unless the compensation meets the definition of "performance based compensation" in the legislation. Non-deductibility could result in additional tax costs to the Company. While the committee cannot assess with certainty how the Company's compensation program will ultimately be affected by OBRA93, the committee generally tries to preserve the deductibility of all executive compensation if it can do so without interfering with the Company's ability to attract and retain capable and highly motivated senior management. Elements of Compensation The elements of the compensation program the committee administers for executive officers, including the Chief Executive Officer, consist of base salaries, annual bonuses, awards made under the Company's Long-Term Incentive Plan, contributions to the Company's 401(k) retirement plan, contributions to the Company's deferred compensation retirement plan, and miscellaneous 14 perquisites. Base salaries, annual bonuses and long-term incentives are discussed separately below; however, the committee considers the aggregate remuneration of executives when evaluating the executive compensation program. Base Salaries. An executive's base salary is viewed as a fixed component of total compensation that should be competitive with companies of similar size and business to the Company. The committee has targeted base salaries at or slightly above the median level for companies of similar size and business to the Company. The committee evaluates the base salaries of the Company's executive officers on the basis of competitive base salary survey data provided by its consultant and consideration of each officer's duties and responsibilities. The committee views the executives below the Chief Executive Officer level as a team with diverse duties but with similar authority and responsibility. Hewitt Associates historically has provided base salary survey data on the majority of the Company's peer group companies, a group of independent exploration and production companies with similar asset, revenue and capital investment profiles as the Company. While the peer group provided by Hewitt Associates includes some of the members of the Dow Jones U.S. Oil Companies, Secondary Index (the "DJ Secondary Oil Index") reflected in the performance graph set forth under "Company Performance" below, it does not include all of the companies in that peer group and includes other companies with which the Company competes. The committee determines the base salary for all executives, including Mr. Sheffield, using the same methodology. For 2003, Mr. Sheffield's annual base salary was not increased and will remain at the 2002 level of $700,000. Hewitt Associates indicated Mr. Sheffield's annual base salary is at or slightly above the 50th percentile. The base salaries of the other named executive officers were also not increased for 2003, and Hewitt Associates advised their 2003 base salaries are, as a group, slightly above the median. Annual Bonuses. Each year the committee establishes a target bonus for each executive based on the target bonus median levels of executives in similar positions at peer group companies. To maintain internal equity, the level of responsibility, scope and complexity of the executive's position are considered. The range of awards for the annual incentive bonus plan can range from 0 to 200 percent of target. The target bonus levels for Mr. Sheffield and the executive officers did not change from the 2002 target bonus levels and were identified by Hewitt Associates as being slightly above the median level. In awarding 2002 bonuses, the Company reviewed the following criteria that are important to the success of the Company's business plan. o Operating cost per BOE o Debt/Book capitalization o Reserve replacement o Growth of share value o Finding and development cost per BOE o Production growth o General and administrative costs o Net asset value In determining the executive officers' annual bonus awards, the committee also evaluated the Company's stock performance in relation to its peer group. The committee did not employ a formula, specific targets or predetermined weighting of the above financial and operational performance criteria. The committee evaluates Company performance in light of oil and gas industry fundamentals and assesses how effectively management adapts to changing industry conditions and opportunities during the year. The committee observes and evaluates the individual performance of executive officers through the year and specifically evaluates Mr. Sheffield's performance relative to the Company's performance in achieving the Company's goals. For 2002, the committee awarded Mr. Sheffield and the other executives cash bonuses above the target bonus levels. Specific Company performance which resulted in bonus payouts above target for 2002 included: o Base operating costs of $2.86 per BOE o Maintained leverage position o Reserve replacement of 258 percent o Finding and development costs of $6.30 per BOE o General and administrative cost of $1.17 per BOE o 2002 stock price increase of 31 percent 15 Regarding stock performance, for the third consecutive year, the Company's annual stock price performance compared to other peer group companies achieved top quartile ranking. Also, the Company's three year cumulative total return based on stock price performance has exceeded both the Standard & Poor's 500 Index (the "S&P 500") and the DJ Secondary Oil Index per the graph below. In addition, the Company's stock price hit a four year high of $27.50 in October, 2002.

A significant portion of an executive officers' total compensation opportunity is comprised of long-term incentive awards, which are intended to align executive management's interests in long-term growth and success more closely with the interests of the Company's stockholders. The committee has determined that a combination of stock option and restricted stock awards is the most appropriate method to meet the Company's long-term incentive plan objectives of rewarding for long-term performance and encouraging retention. The additional emphasis on restricted stock was achieved by reducing the value of the stock options awarded over a three-year period by the value of the restricted stock awards. The restricted stock includes a three year cliff vesting restriction and was designed to be a one time award to replace a like value of stock options that would have been issued over the next three years. The value of the long-term incentive awards granted to Mr. Sheffield in 2002 was determined by a comparison of long-term incentive grants made to the Chief Executive Officers' of peer group companies. The other executive officers were reviewed as a team. The value of long-term incentives granted to each executive was determined by comparing the value of awards granted to peer company executives holding similar positions, and their individual award levels were averaged to determine the actual awards to executives of the Company. The award levels were not influenced by the current stock holdings of the executives. The Company's philosophy is to award long-term incentives with values that are above market average. For 2002, Mr. Sheffield was awarded 150,000 stock options and 72,000 shares of restricted stock. Hewitt Associates concluded the 2002 award levels placed Mr. Sheffield and the other executives as a group slightly above the 60th percentile for long-term incentive awards among the peer group. In summary, the Company believes a significant portion of executive compensation should be variable and performance-based so that an executive's total compensation opportunity is linked to the performance of the individual, the Company and its stock price. The majority of an executive officers' total compensation is variable and at-risk. This structure allows the Company to administer overall compensation that rises or falls based on the Company's performance while maintaining a balance between the Company's short-term and long-term objectives. Compensation Committee of The Board of Directors Charles E. Ramsey, Jr., Chairman James R. Baroffio, Member Edison C. Buchanan, Member 17 AUDIT COMMITTEE REPORT The Audit Committee's purpose is to assist the Board of Directors in its oversight of the Company's internal controls, financial statements and the audit process. The Board of Directors, in its business judgment, has determined that all members of the committee are independent as required under the listing standards of the New York Stock Exchange. The committee operates pursuant to a charter adopted by the Board of Directors. A copy of the current charter is attached to this proxy statement as Annex A. Management is responsible for the preparation, presentation and integrity of the Company's financial statements, accounting and financial reporting principles, and internal controls and procedures designed to assure compliance with accounting standards and applicable laws and regulations. The independent auditors, Ernst & Young LLP, are responsible for performing an independent audit of the consolidated financial statements in accordance with generally accepted auditing standards. In performing its oversight role, the committee has reviewed and discussed the audited financial statements with management and the independent auditors. The committee has also discussed with the independent auditors the matters required to be discussed by Statement on Auditing Standards No. 61, Communication with Audit Committees, as currently in effect. The committee has received the written disclosures and the letter from the independent auditors required by Independence Standards Board Standard No. 1, Independent with Audit Committees, as currently in effect. The committee has also considered whether the performance of other non-audit services by the independent auditors is compatible with maintaining the auditor's independence and has discussed with the auditors the auditors' independence. Based on the reports and discussions described in this Report, and subject to the limitations on the roles and responsibilities of the committee referred to below and in the charter, the committee recommended to the Board of Directors that the audited financial statements be included in the Annual Report on Form 10-K for the fiscal year ended December 31, 2002, for filing with the Securities and Exchange Commission (the "SEC"). The committee has also recommended the selection of the Company's independent auditors. The members of the committee are not professionally engaged in the practice of auditing or accounting for the Company and are not experts in auditor independence standards. Members of the committee rely without independent verification on the information provided to them and on the representations made by management and the independent auditors. Accordingly, the committee's oversight does not provide an independent basis to determine that management has maintained appropriate accounting and financial reporting principles or appropriate internal controls and procedures designed to assure compliance with accounting standards and applicable laws and regulations. Furthermore, the committee's considerations and discussions referred to above do not assure that the audit of the Company's financial statements has been carried out in accordance with generally accepted auditing standards, that the financial statements are presented in accordance with generally accepted accounting principles, or that Ernst & Young LLP is in fact independent. Audit Committee of The Board of Directors James L. Houghton, Chairman R. Hartwell Gardner, Member Jerry P. Jones, Member Linda K. Lawson, Member Robert A. Solberg, Member 18 CORPORATE GOVERNANCE Corporate Governance Principles The Board of Directors believes that sound governance practices and policies provide an important framework to assist it in fulfilling its duty to shareholders. In March 2003, the Board of Directors formally adopted the Pioneer Natural Resources Company Corporate Governance Principles , which cover the following principal subjects: o Role and functions of the board o Qualifications and independence of directors o Committee functions and independence of committee members o Meetings of non-employee directors o Self-evaluation o Ethics and conflicts of interest policy (a copy of the current Code of Business Conduct and Ethics is attached to this annual proxy statement as Annex D) o Reporting of concerns to non-employee directors or the Audit Committee o Compensation of the board and stock ownership requirements o Succession planning and annual compensation review of senior management o Access to senior management and to independent advisors o Director orientation and continuing education o Evaluation of corporate governance principles The Corporate Governance Principles are attached to this proxy statement as Annex E and are posted on the Company's website at www.pioneernrc.com. The Corporate Governance Principles will be reviewed periodically and as necessary by the Company's Nominating and Corporate Governance Committee, and any proposed additions to or amendments of the Corporate Governance Principles will be presented to the Board of Directors for its approval. The New York Stock Exchange (the "NYSE") has proposed rules that would require listed companies to adopt governance guidelines covering certain matters. The Company believes that the Corporate Governance Principles comply with the proposed rules. Director Independence The Company's existing standards for determining director independence require the assessment of directors' independence on an annual basis. In March 2003, the Board of Directors assessed the independence of each director in accordance with its then-effective independence standards for directors, which generally define an independent director as one who does not have any relationship with management or the Company that may interfere with the exercise of his or her independent judgement. The Board of Directors has determined, after careful review, that each member of the Board of Directors is independent, with the exception of Mr. Sheffield, who is an employee of the Company. Accordingly, eight out of the nine current members of the Board of Directors are independent directors. The NYSE has proposed rules that would adopt a revised definition of director independence for listed companies. Upon final approval of such rules, the Board of Directors will amend the Corporate Governance Principles as necessary to ensure that the Company's standards for director independence meet or exceed those in the final rules, and will thereafter evaluate director independence in accordance with those standards. Based on the rules as proposed at the time of the Board of Director's evaluation of independence in March 2003, the Board of Directors believes that all non-employee directors would be independent under the proposed rules. Election of Lead Director In February 2003, the Board of Directors elected Mr. Ramsey, a non-employee director, to serve as chairman of the regular private meetings of the independent directors, and as Chairman of the Company's Nominating and Corporate Governance Committee (the "Lead Director"). Utilizing input from all 19 directors, the Lead Director will work with the CEO and Chairman of the Board to determine the appropriate agenda and information package for Board of Director meetings; meet with the CEO and Chairman of the Board, senior management and individual directors, as required, to facilitate effective communications and information flow; take a leadership role in CEO succession and senior management development; take a leadership role in director evaluation, continuing education, recruiting and orientation; and serve as the Board of Directors contact in the process for direct employee and stockholder communications with the Board of Directors. Financial Literacy of Audit Committee and Designation of Financial Experts In March 2003, the Board of Directors evaluated the members of the Audit Committee for financial literacy and the attributes of a financial expert. The Board of Directors determined that each of the Audit Committee members is financially literate and that three of the Audit Committee members (Mrs. Lawson and Messrs. Gardner and Houghton) are financial experts as recently defined by the SEC.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE The executive officers and directors of the Company are required to file reports with the SEC, disclosing the amount and nature of their beneficial ownership in common stock, as well as changes in that ownership.

Spratlen, the Company's Vice President - Investor Relations and Communication, did not timely file one report on Form 4 covering one transaction effected during 2002. Other than as discussed above, the Company believes that all required reports were filed on time for 2002. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS During 2002, the Company did not enter into any transactions with management and others, nor was it a party to business relationships or other arrangements or transactions, that would be reportable as certain relationships and related transactions. Mr. Jones is of counsel to the firm of Thompson & Knight, L.L.P. since his retirement from the firm in January 1998. Thompson & Knight, L.L.P. provide periodic legal services to the Company. Thompson & Knight, L.L.P. customarily gives the "of counsel" title to retired partners of the firm. Mr. Jones has no role in, and receives no pay from, Thompson & Knight, L.L.P. except payments under a retirement savings plan. Accordingly, the Board of Directors does not consider this relationship to be relevant to Mr. Jones' independence.

Consistent with this Purpose, the Committee should encourage continuous improvement of, and should foster adherence to, the Company's policies, procedures and practices at all levels. The Committee will primarily fulfill these responsibilities by carrying out the activities enumerated in Section V of this Charter. II Composition The Committee shall be comprised of three or more Directors, as determined by the Board or a nominating committee of the Board, none of whom shall be an affiliate of the Company or an employee or a person who receives any compensation from the Company other than fees paid for service as a Director. The members of the Committee shall be elected by the Board or a nominating committee of the Board annually and shall serve until their successors shall be duly elected and qualified. Each member shall be "independent" as defined from time to time by the listing standards of the New York Stock Exchange (the "NYSE") and by applicable regulations of the Securities and Exchange Commission 26 (the "SEC") and shall meet any other applicable independence requirements of the NYSE and SEC. Accordingly, the Board shall determine annually whether each member is free from any relationship that may interfere with his or her independence from management and the Company. No member shall serve on an audit committee of more than two other public companies unless the Board determines that such simultaneous service would not impair the ability of such director to effectively serve on the Committee. Each member shall be (or shall become within a reasonable time after appointment) financially literate, and at least one member shall be a "financial expert" as defined from time to time by applicable regulations of the SEC. Members of the Committee may enhance their familiarity with finance and accounting principles by participating in educational programs that the Company or an outside consultant conducts. Notwithstanding the foregoing membership requirements, no action of the Committee shall be invalid by reason of any such requirement not being met at the time such action is taken. III Meetings and Structure The Committee shall meet at least four times per year to review the financial information of the Company, consistent with its duties and responsibilities, and as many additional times as the members deem necessary. As a part of its effort to foster open communications, the Committee should meet at least annually with management, the director of the internal auditing department, and the independent auditors in separate executive sessions to discuss any matters that the Committee or each of these groups believe should be discussed privately. Unless the Board designates a Chair of the Committee, the members of the Committee shall, by majority vote of the full Committee membership, appoint one member of the Committee as chairperson. He or she shall be responsible for leadership of the Audit Committee, including preparing the agenda, presiding over the meetings, making committee assignments and reporting to the Board.

The Committee, or a member thereof, must pre-approve any non-audit service provided to the Company by the Company's independent auditors. V Authority and Responsibilities The Committee shall have the authority to take all actions it deems advisable to fulfill its responsibilities and duties. The Committee shall have the authority to retain professional advisors including, without limitation, special legal counsel, accounting experts, or other consultants to advise the Committee, which may be the same as or different from the Company's primary legal counsel, accounting experts and other consultants as the Committee deems necessary or advisable in connection with the exercise of its powers and responsibilities as set forth in this Audit Committee Charter, all on such terms as the Committee deems necessary and advisable. The Committee may require any officer or employee of the Company or any of its subsidiaries, the Company's outside legal counsel, and the Company's external auditors to attend a meeting of the Committee or to meet with any member of, or consultant to, the Committee. The Committee chairperson, or other designee of the Committee, may also meet with the Company's investment bankers or financial analysts who follow the Company. The Committee shall be responsible for the resolution of any disagreements between the independent auditors and management regarding the Company's financial reporting.

The Code outlines specific guidelines for conduct in situations that affect all employees. Such principles and guidelines are to be adhered to at all times and under all circumstances and are applicable to all directors, officers and employees of the Company. Unless specifically addressed herein, when the term "Employee(s)" is used herein it also applies to all of the officers and directors of the Company. All employees of the Company are expected to be guided by the basic principles of honesty and fairness in the conduct of the Company's affairs. Employees are encouraged to ask questions and voice concerns about the meaning or application of the Company's business practices and compliance with applicable laws and regulations. Enforcement of sound ethical standards is the responsibility of every director, officer and employee of the Company. Employees are expected to report suspected violations of Company policies and internal control procedures or to make complaints regarding accounting, internal accounting controls or accounting matters or to express concerns regarding questionable accounting or auditing matters promptly to the Company's General Counsel or the Audit Committee of the Board of Directors. With the "Compliance Line," the Company provides employees with a confidential means to report any such suspected violations or complaints. No action will be taken or threatened against any employee for making a complaint or disclosing information to the employee's supervisor or management personnel unless (1) the complaint or disclosure was made with the knowledge that it was false or with willful disregard for its truth or accuracy, or (2) the employee was involved in the improper activity. The Compliance Line number is 1-800-750-4972. The Board of Directors of the Company is charged with enforcing compliance with this Code to ensure that the Company conducts itself in a manner consistent with its obligations to society and its stockholders. The Board has established procedures to monitor compliance. Violations by any employee will subject the employee to disciplinary action, and in certain cases, discharge from employment. Due to the seriousness of this subject, any employee, officer or director with any doubts about the applicability of this Code should talk to the appropriate level of higher management or the Company's General Counsel. This Code of Business Conduct and Ethics supersedes and replaces the Statement of Policy on Standards of Business Conduct of the Company and that Statement of Policy on Ethics and Conflicts of Interest of Parker & Parsley Petroleum Company dated January 1, 1993 and policies of a similar nature of the corporate predecessors of the Company. SECTION II ETHICS AND COMPLIANCE WITH ALL LAWS AND REGULATIONS POLICY: The Company will conduct its business in accordance with the highest ethical and legal standards. The Company is committed to being a good corporate citizen of all states and countries in which it does business. Employees must understand that the Company does care how results are obtained, not just that they are obtained. The Company supports any employee who passes up an opportunity or advantage which would sacrifice the Company's ethical standards. Therefore, it continues to be the policy of the Company to comply in all respects with all laws and regulations that are applicable to its business, at all government levels in the United States 39 and abroad. If a law conflicts with a policy in this Code, the law must be followed; however, if local custom or policy conflicts with this Code, this Code must be followed. Any employee who does not adhere to these standards is acting outside the scope of employment or agency. The Company expects employees to report suspected violations of laws or Company policies to Company management. Other sections of the Code deal with specific laws and regulations and outline general guidelines for compliance with such laws and regulations due to their particular importance to the Company's business activities. The special emphasis on these laws does not limit the general admonition to comply with all applicable laws, regulations and judicial decrees of the United States (federal, state and local) and of other countries where the Company transacts business. The Company expects candor from its officers and managers and compliance with Company policies and rules. Because attempts by officers and managers to conceal information from higher management or the auditors might be seen by subordinates as a signal that Company policies and rules can be ignored when inconvenient, officers and managers will be strictly accountable. No officer or employee should at any time take any action on behalf of the Company which he or she knows or reasonably should know would violate any law or regulation. The Company's interests are not served by unethical practices and activities even if the practices and acts are not in technical violation of the law. An officer or employee having even the slightest question as to the validity of any action proposed to be taken on behalf of the Company should immediately contact the Company's General Counsel for advice. SECTION III CONFLICTS OF INTEREST POLICY: It is the policy of the Company that all directors, officers and other employees avoid any conflict between their personal interests and the interests of the Company in dealing with suppliers, customers, competitors, organizations and third parties. Employees, officers and directors may not use their positions, Company assets, or confidential information gained in connection with their employment or involvement with the Company for personal gain or for the benefit of a family member or any outside party. It is not feasible to specify all activities that may give rise to a conflict of interest; however, they generally occur in the areas of personal investments, affiliations, business gifts and confidential information. The following examples will serve as a non-exclusive guide to the circumstances or types of activities that could cause conflicts and therefore are prohibited unless specifically approved in writing by the Company through the employee's supervisor or officer in charge of the employee's department, or in the case of an officer, the Management Committee officer to whom such officer reports; and then with such approval forwarded for review to a) the Management Committee officer who has responsibility for the employee's or officer's department and b) the Company's General Counsel: (1) Ownership, by an employee or any immediate family member (spouse, parents, children and their spouses) or associate, of any financial interest in any non-public enterprise that does business with, or is a competitor of, the Company. (2) Ownership, by an employee or immediate family member, of 2% or more of the outstanding shares of any publicly owned corporation regularly traded on any open market that does business with, or is a competitor of, the Company. (3) Participation in any outside activity that competes directly or indirectly with the Company or that interferes with (or has the appearance of interfering with) the performance of the employee's duties to the Company. (4) Service as a director, consultant or employee of an enterprise that conducts or seeks to conduct business with the Company. This does not include appointment to a position in an outside company as a representative of the Company. 40 (5) Acceptance by an employee or close relative or associate of gifts of a size that may tend to influence the employee's business decisions or compromise the employee's independent judgment. In addition to excessive size gifts, prohibited situations requiring Company approval before acceptance also include, but are not limited to: loans, excessive entertainment, discounts, hunting or fishing trips, golf outings, tickets to shows or athletic games, services, sponsorships, contributions or other special favors from any individual, enterprise or organization that does or is seeking to do business with, or is a competitor of, the Company. Acceptance of minor gifts such as meals and refreshments for immediate consumption, entertainment, routine promotional sales gifts and other items of nominal value are not prohibited by this provision provided such acceptance is in keeping with good business ethics, gives no appearance of impropriety, does not result in special or favored treatment for the donor and no effort is made to conceal the full facts by the recipient or the donor and it does not create or imply a business obligation or otherwise create a conflict between the employee's personal interests and the best interests of the Company. (6) Ownership, by an employee, immediate family member, or associate, of a contractual or real property interest (including royalty, working interest, net profits interest, etc.) in any property owned or operated by the Company or any of its subsidiaries or affiliates, other than an interest acquired through a Company sponsored program. (7) Disclosure or use by an employee of information that is confidential, proprietary or privileged, for the benefit or gain of the employee or any other person. The obligation to preserve confidential, proprietary or privileged information continues even after employment or agency with the Company ends. (8) Use of Company opportunities discovered or learned through use of Company information or one's Company position for personal gain or the gain of any other person. In the event that an employee senses possible involvement in a conflict of interest situation, the employee should immediately report the matter to his or her supervisor, making a full disclosure of all pertinent facts and circumstances. The Company will develop a form for use by employees for reporting such matters. Because each case may involve special circumstances, it will be judged on its own merits considering the duties of the employee and the relative significance of the factors involved. Directors and Management Committee officers, while not required to get pre-approval for the types of activities referenced in paragraphs (1) through (8), above, must promptly disclose any such conflicts or potential conflicts to the Company's General Counsel for periodic review by the Company's Audit Committee and Board. Failure by any employee or officer to seek approval for, or in the case of directors and Management Committee officers, to disclose, an activity which, in the opinion of management or, in the case of directors and Management Committee officers, the Board, would result, or has resulted, in a conflict of interest, may result in disciplinary action up to and including discharge from employment. In addition, the Board will take appropriate disciplinary action against any Management Committee officers and directors whose disclosures reveal activities which, when reviewed by the Audit Committee and Board, are determined to have been a conflict of interest. SECTION IV HUMAN RESOURCES, EQUAL EMPLOYMENT OPPORTUNITY AND NON-HARASSMENT POLICY: The Company recognizes that its greatest assets are its employees and realizes that the proper utilization, development and protection of the Company's human resources are the key to continued success. It is the policy of the Company to provide equal employment opportunity in conformance with all applicable laws and regulations to individuals who are qualified to perform job requirements, regardless of their race, color, sex, religion, national origin, age, physical or mental handicap, or veteran's status. Equal opportunity shall be provided in all aspects of the employment relationship. Further, the Company expressly prohibits any form of unlawful employee harassment based on race, color, sex, religion, national origin, age, physical or mental handicap, or veteran status. The Company's objective is 41 to provide a work environment that encourages mutual employee respect and working relationships free of harassment. Harassment, whether it occurs in the workplace or at a Company-sponsored function, will not be tolerated. Forms of harassment include, but are not limited to unwelcome verbal or physical advances and sexually, racially or otherwise derogatory or discriminatory materials, statements or remarks. All employees, including supervisors and managers, will be subject to disciplinary action up to and including termination for any act of harassment. Supervisors and managers have particular responsibility for maintaining a work environment free from discrimination and harassment and for the prompt identification and resolution of any problem areas regarding such issues. Employees of Pioneer Natural Resources USA, Inc. ("Pioneer") should refer to the "Policy Guides for Employees" for the procedures implementing and enforcing this policy with regard to Pioneer. SECTION V RELATIONSHIP WITH GOVERNMENTAL OFFICIALS POLICY: No funds or assets of the Company shall be paid, directly or indirectly, in violation of applicable law, to any government official, either inside or outside of the United States, or to any enterprise owned or controlled by any government official. A great deal of public attention has been directed to questionable payments that some corporations have made to government officials both in this country and abroad. The purpose of this Code is to reiterate the Company's longstanding policy in the clearest possible terms. The success of the Company's operations depends, to a great degree, upon its ability to build relationships with government officials and employees based on honesty and integrity. Payments, regardless of amount, or gifts of entertainment (of more than nominal value) to government officials and other government personnel of the United States and other domestic or foreign jurisdictions, regardless of motive, are viewed by the Company as improper and are not permitted. In addition, laws such as the Foreign Corrupt Practices Act, which is a U.S. law prohibiting bribery of foreign officials, provide for serious criminal and civil penalties against corporations, employees, officers and directors. The relationships of Company personnel with public officials should in all respects be of such an open and forthright nature that the integrity and reputation of the officials and the Company will not be impugned in the event the full details of the relationship, including any gifts or entertainment, become a matter of public record. SECTION VI COMMERCIAL BRIBERY POLICY: No funds or assets of the Company shall be paid, loaned or otherwise disbursed as bribes, kickbacks or other payments designed to influence or compromise the conduct of the recipient, and no officer or employee of the Company shall accept any funds or other assets for assisting and obtaining business or securing special concessions from the Company or any other person or legal entity. The Company considers one of its most valuable assets to be its reputation and integrity. It seeks stable and profitable business relationships -- based on integrity -- with its employees, customers, suppliers and all others whose activities touch upon its own. To that end, Company's directors, officers, employees and agents should conduct their business affairs so as to guard and protect the Company's reputation. By way of illustrating the strict ethical standards that every director, officer, employee and agent is expected to maintain, the following conduct is expressly prohibited: (1) Payment or receipt of money, gifts, loans or other favors that may tend to influence business decisions with respect to the Company or compromise independent judgment. (2) Payment or receipt of rebates or kickbacks for obtaining business for the Company. 42 (3) Payment of bribes to government officials, such as tax authorities, to obtain favorable rulings on issues of local law for the Company. Any other activities of this nature that, though not enumerated, could degrade the Company's reputation and integrity are also prohibited. These guidelines are not intended to prevent the Company from paying normal and reasonable commissions to its agents, from taking normal prompt payment discounts, and also from giving or receiving gifts or services that comport with normal and customary social amenities and that do not tend to compromise the conduct of the recipient. Should an officer, employee or agent be requested to make or accept a gift or payment that is prohibited by this Code, disclosure of the request and all the surrounding circumstances should be made immediately to his or her supervisor. If any situation arises in which the propriety of such request is in the least manner questionable, the General Counsel of the Company should be consulted for resolution of the question. SECTION VII PROPER RECORDING OF FUNDS, ASSETS AND DISBURSEMENTS POLICY: All funds, assets, receipts and disbursements of the Company shall be properly recorded on the books of the Company. To assure that this policy is implemented, it is specifically understood that: (1) No funds or accounts shall be established or maintained for purposes that are not fully and accurately reflected on the books and records of the Company. (2) No funds or other assets shall be received or disbursed without being fully and accurately reflected on the books and records of the Company. (3) No false, fictitious or intentionally misleading entries shall be made on the books or records of the Company, and no false or misleading reports pertaining to the Company or its operations shall be issued. Any officer or employee having knowledge of any act or circumstance that is prohibited by this policy shall immediately report the matter to the Company's General Counsel and Audit Committee. SECTION VIII SUBSIDIARIES AND AFFILIATES POLICY: All personnel of the Company who act as Company representatives on the boards of directors, or in other management positions, of subsidiaries or affiliates of the Company are expected to cast their votes, exert their influence and otherwise conduct their activities in a manner which will promote the observance of the policies in this Code by such subsidiaries and affiliates, subject to their fiduciary obligations, if any, associated with the nature of their representative positions. SECTION IX ENVIRONMENTAL AND TOXIC SUBSTANCES POLICY POLICY: The Company has long been committed to the goal of safe, efficient and environmentally sound business practices and operations and has been supportive of endeavors aimed at preserving our environmental heritage. Such commitment is entirely consistent with the Company's economic goals and is in the best interests of its shareholders. The Company shall conduct its business in a manner that protects employees, others involved in its operations and the public from unacceptable risks due to toxic substances which are produced or used in the Company's business. The Company is committed to continuous efforts to identify and manage risks associated with such substances. In addition, in the conduct of its 43 business it is the Company's policy to comply with all applicable environmental laws and regulations and not to condone any failure by Company employees to comply with such laws and regulations. The Company is committed to complying with all applicable laws and regulations relating to protection of the environment as well as to using all reasonable efforts to operate in a manner that preserves the environment and conserves natural resources. Numerous federal, state and local laws and regulations exist which involve the protection of the environment. These laws and regulations are diverse and far-reaching. Violation can produce severe consequences not only for the Company but for any employee involved in a violation. In the conduct of the Company's operations and business, each officer and employee is required to comply with all applicable laws and regulations relating to the protection of the environment. Any employee having questions about environmental laws or regulations should consult the office of the Company's General Counsel. SECTION X SAFETY POLICY: It is the Company's policy to conduct its operations and business in a manner that protects the safety of employees, others involved in its operations and the public. The Company will strive to prevent all accidents, injuries and occupational illnesses through the active participation of every employee. The Company is committed to complying with all applicable laws and to continuous efforts to identify and eliminate or manage safety risks associated with its activities. The Company is committed to complying with all applicable laws and regulations relating to maintenance of a safe workplace. Each employee should perform his or her duties in a manner that will not endanger the employee or others. Employees are required to use such safety equipment as may be required by law, regulation or by Company manuals, handbooks and guidelines. Employees are also required to use all reasonable efforts to maintain the work area in such condition as will not pose a safety hazard for themselves or others. Employees are encouraged to identify ways to improve safety and to bring these to the attention of the supervisors. SECTION XI ANTITRUST LAWS POLICY: It is in the best interest of the Company, as well as that of its stockholders and employees to have vigorous and fair competition. The antitrust laws were conceived and enacted as a means for helping to preserve the free enterprise system by promoting healthy competition. It is the policy of the Company that all its directors, officers and employees shall, in carrying out their duties to the Company, comply in all respects with the spirit as well as the letter of such antitrust laws, domestic and foreign. In circumstances where there is a legitimate doubt as to the proper interpretation of the law it is required that the matter be referred through appropriate channels to the Company's General Counsel for advice. In the United States the body of laws that are generally referred to as antitrust laws is a collection of statutes that have been enacted over a period of many years both by the federal government and the various states. These laws prohibit business practices that constitute unreasonable restraints of trade, unfair trade practices and other anti-competitive activities. Depending on the circumstances, certain prohibited practices include the following: (1) Creation of a monopoly or attempts to create a monopoly; (2) Agreements among competitors to increase, decrease or stabilize prices; to divide territories or markets; to allocate customers; to limit the quality of products or to limit the production of products; and (3) Discrimination in price and other predatory trade practices. 44 Any failure to comply with antitrust laws can have far reaching affects, not only on the Company, but also upon each employee involved in the violation. Any employee having any question concerning compliance with antitrust laws should seek advice from the office of the Company's General Counsel. No employee of the Company has any authority whatsoever to engage in any activity that could constitute a violation of the antitrust laws and all employees are specifically directed not to do so. This direction is without any qualification, limitation or restriction whatsoever. SECTION XII ELECTION CAMPAIGN LAWS POLICY: No funds or assets of the Company shall be contributed to any political party or organization, or to any individual who either holds public office or is a candidate for public office, except where such contribution is permitted by applicable law and has previously been authorized by the Board of Directors or Management Committee of the Company. Federal and state laws restrict the contribution of corporate funds to candidates for federal, state or local office or to committees formed to support such candidates or advocate their political causes. The Company requires strict compliance with these laws. The following are examples of activities for candidates or committees that are prohibited by these laws and by the policy of the Company: (1) Contributions by an employee that are reimbursed through expense accounts or in other ways; (2) Purchases by the Company of tickets for special dinners or fund raising events; (3) Contributions in kind, such as: a) the loaning of employees to political parties; or, b) the use of Company assets in political campaigns; and (4) Indirect contributions by the Company through suppliers, customers or agents. It is acknowledged that political contributions by corporations are permitted by the laws of some states and in some foreign countries they are not only permitted but expected. Even under these circumstances, no Company funds or assets shall be used for political purposes without the express authorization of the Board of Directors or Management Committee of the Company. Any officer or employee of the Company who fails to comply with the Company policy regarding corporation contributions and expenditures in connection with political activities shall be subject to appropriate disciplinary action, which may include discharge. However, the Company's policy does not prohibit any officer or employee from engaging in political activities in an individual capacity (not as a representative of the Company) on his or her own time and own expense, or from making political contributions from personal funds, or from expressing personal views with respect to legislative or political matters. SECTION XIII ADMINISTRATION Reinforcement of sound ethical standards is the responsibility of every director, officer and employee of the Company. Nevertheless, all violations and reasonable suspicions of violations of this Code shall be promptly reported to the employee's department manager or supervisor, or the office of the General Counsel, by the individual with knowledge of such a violation. This Code, as amended from time-to-time, may be supplemented or implemented by more detailed procedures, guidelines, manuals and handbooks issued by the Company or its subsidiaries or affiliates. The Company reserves the right, in its sole discretion, to amend, modify, interpret, supercede or rescind any or all of the policies described in this Code, with or without notice. Any amendment to this Code shall be made only by the Company's Board of Directors or the appropriate committee thereof. If an amendment to this Code is made, appropriate disclosure will be made in accordance with legal requirements and stock exchange regulations. 45 Every director, officer or employee elected or employed after the effective date of this Code may be required to sign a written affirmation acknowledging that they have read and understood this Code and will comply with the Code, which affirmation may be separate or part of another affirmation or acknowledgment relating to employee manuals, handbooks, benefit packages, etc., supplied to new directors, officers or employees. This signed affirmation shall be retained on file in the Human Resources Department. All employees, directors and officers shall be required from time to time to sign a written affirmation stating they (1) have read this Code and understand its contents, (2) have not violated this Code, (3) will continue to comply with the Code and (4) have no knowledge of any violation of this policy which has not been previously communicated to their supervisor or the office of the General Counsel or the Audit Committee of the Board of Directors. Waivers of any provision of this Code shall be made only by the Audit Committee of the Board of Directors, or the full Board. Persons seeking a waiver should be prepared to disclose all pertinent facts and circumstances, respond to inquiries for additional information, explain why the waiver is necessary, appropriate, or in the best interest of the Company, and comply with any procedures that may be required to protect the Company in connection with a waiver. If a waiver of this Code is granted for any officer, appropriate disclosure will be made in accordance with legal requirements and stock exchange regulations. SECTION XIV CONCLUSION The Company, as a publicly traded company, has certain obligations to its stockholders as well as to society in general. These obligations and the Company's commitment to open, honest, straightforward and ethical conduct including full, fair, accurate, timely and understandable disclosure in reports and documents that the Company files with, or submits to, the United States Securities and Exchange Commission and in other public communications made by the Company, warrant the implementation and enforcement of this Code of Business Conduct and Ethics. It is quite clear to the Company that its reputation for honesty and integrity is a direct result of the standards and acts of its directors, officers and employees. The Company, its stockholders and the general public expect and are entitled to have the Company conduct itself in a manner consistent with basic principles of honesty and fairness and the principles set forth in this Code. Therefore, violations by any officer or employee will result in appropriate disciplinary action, including dismissal when necessary. 46 Annex E PIONEER NATURAL RESOURCES COMPANY CORPORATE GOVERNANCE PRINCIPLES The mission of the Board of Directors (the "Board") of Pioneer Natural Resources Company ("Pioneer" or the "Company") is to be a strategic asset to the Company, both collectively and as individual directors ("Directors"), measured by the contribution it makes to the long-term success of the Company and the creation of stockholder value. Governance Principles The following Principles have been approved by the Board to emphasize its strong commitment to good corporate governance practices. Along with the charters and key practices of the Board committees, these Principles are designed to provide the framework for the governance of Pioneer and to assist the Board in the performance of its duties and the exercise of its responsibilities. The Board recognizes that the issues involved in corporate governance are dynamic and iterative and it will review these Principles and other aspects of Pioneer governance not less than every three years or more often if deemed necessary. These Principles, as well as the charters of the Board committees, the Company's Bylaws and its Code of Business Conduct and Ethics, are all published on Pioneer's corporate website and are available in print to any stockholder who requests them. 1. Role of Board and Management. The business and affairs of Pioneer are conducted and managed by its employees, officers and chief executive officer ("CEO") under the direction and oversight of the Board, to enhance the long-term value of the Company for its stockholders. The Board is elected by and accountable to the stockholders to oversee management, to provide strategic direction and to assure that the long-term interests of the stockholders are being served. In carrying out its responsibilities, the Board will exercise sound, informed, and independent business judgment. Both the Board and management recognize that the long-term interests of stockholders are advanced by responsibly addressing and adhering to good corporate governance principles. The Board also recognizes that to do so requires individual preparation by each Director and group deliberation by the Board, and that the Board's responsibilities include both decision-making and oversight. 2. Functions of Board. The Board schedules a minimum of four meetings a year, held quarterly, at which it reviews and discusses presentations by management on the performance of the Company, progress towards its goals, its strategic plans and prospects, as well as immediate issues confronting Pioneer. The Board also holds additional informational sessions each year called periodically by the CEO as required to update the Board on important operational and other material events. Except in extenuating circumstances, Directors are expected to attend all scheduled meetings of the Board and of committees on which they serve. As a part of its oversight responsibilities, among other things, the Board monitors: a. the performance of the Company; b. the performance and effectiveness of the CEO and Management; c. the selection, evaluation, development and compensation of senior management; d. the Company's compliance with legal requirements and ethical standards; e. the Company's financial reporting and disclosure processes and internal controls; and 47 f. the Company's processes for maintaining the integrity of the financial statements, the integrity of compliance with law and ethics, the integrity of relationships with partners, working interest owners, land and mineral owners and suppliers. In addition to its general oversight of management, the Board also performs a number of specific decision making functions, including, among other things: a. reviewing, approving and monitoring the Company's mission, strategies, objectives and policies as developed by Management; b. selecting the CEO; c. evaluating and compensating the CEO and overseeing CEO succession planning; d. selecting nominees for Board membership; e. approving material investments or divestitures, strategic transactions, and other significant transactions that are not in the ordinary course of the Company's business; f. reviewing, approving and monitoring fundamental financial and business strategies; g. assessing major risks facing the Company and reviewing options for their mitigation; and h. evaluating the performance of the Board and Committees of the Board. 3. Qualifications. Directors should possess the highest personal and professional ethics, integrity and values, and be committed to representing the long-term interests of the stockholders. They also should be intelligent, inquisitive, independent and objective in thought, have practical wisdom and mature judgment and a willingness to gain an understanding of Pioneer, its competitive position in its industry and its business strategy. Pioneer endeavors to have a Board representing diverse experience at policy-making levels with a complimentary mix of skills and experience in areas relevant to the Company's global activities. Among other things, the Board expects each Director to: a. understand Pioneer's businesses and the marketplaces in which they operate; b. review the materials provided in advance of meetings and any other materials provided to the Board from time to time, and to take the time and effort to be fully informed on the materials and issues presented; c. strive for a collegial atmosphere showing mutual respect for all Directors and opinions; d. actively, objectively and constructively participate in meetings and the strategic decision-making processes; e. share his or her perspective, background, experience, knowledge and insights as they relate to the matters before the Board and its committees; f. make decisions based on his/her honest, independent opinion of merit and the best long-term interest of Pioneer; and g. be available when requested to advise the CEO and Management on specific issues not requiring the attention of the full Board, but where an individual Director's insights might be helpful to the CEO or Management. Directors must be willing to devote sufficient time to carrying out their duties and responsibilities effectively, and should be committed to serving on the Board for an extended period of time. The Company values the experience 48 Directors bring from other boards on which they might serve and other activities in which they participate, but recognizes that those boards and activities may also present demands on a Director's time and availability that may present conflicts or legal issues, including independence issues. Directors should advise the chairperson of the Nominating and Corporate Governance Committee and the CEO before accepting membership on other boards of directors or any Audit Committee or other significant committee assignment on any other board of directors; or before establishing other significant relationships with businesses, institutions, governmental units or regulatory entities, particularly those that may result in significant time commitments or a change in the Director's relationship to the Company. The Board believes that individuals should limit the number of boards of publicly traded, for-profit corporations on which they serve in order to give proper attention to their responsibility to each board. As a general policy, the Board believes that Directors should limit their service to not more than three boards of publicly traded companies in addition to that of the Company, but exceptions to this policy may be made in appropriate cases. Where a Director seeks to serve on more than three such boards, he/she should seek and obtain approval of the Nominating and Corporate Governance Committee for that service. At its discretion, the Nominating and Corporate Governance Committee may refer the approval to the full Board. Members of Pioneer's Audit Committee who seek to serve on the Audit Committee of another public company where that service will result in more than two public company Audit Committee memberships simultaneously, should seek and obtain a determination from the Company's Board in advance of accepting such service, that such service will not impair the ability of such Director to effectively serve on Pioneer's Audit Committee. All memberships on other boards by the CEO will be considered and decided by the full Board based upon the Nominating and Corporate Governance Committee's recommendation. As a general rule, the Board will discourage the CEO from serving on more than two boards in addition to the Board of the Company. Regardless of whether Nominating and Corporate Governance Committee or Board approval is required for service on other boards, a Director seeking to serve on another board should notify the Nominating and Corporate Governance Committee, the CEO and the General Counsel in advance of accepting such service, and should defer final acceptance of such a position until advised by the CEO or General Counsel that such service does not present legal or other serious problems for Pioneer. The General Counsel will be expected to coordinate resolution (if possible) or communication of any legal or business issues as expeditiously as possible. The Board does not believe that arbitrary term limits on Directors' service are appropriate, nor does it believe that Directors should expect to be renominated annually until they reach the mandatory retirement age. The Board self-evaluation process will be an important determinant for Board tenure. Directors of the Company shall not be nominated, elected, or stand for re-election after reaching the age of 75, or if they will reach the age of 75 during the first year of such a term. Directors who reach the age of 75 during their term of office as a Director must immediately resign or be removed from the Board as a mandatory retirement. Unless the Board affirmatively determines otherwise, any member of management who is a Director will retire from the Board at the same time he or she retires from active service with the Company, and will resign from the Board at the same time he or she ceases employment with the Company for any reason. If an outside Director's principal position, status or employment should substantially change, the Director shall submit his or her resignation to the Lead Director. The Nominating and Corporate Governance Committee shall decide whether to accept the resignation. 4. Independence of Directors. While the Board recognizes that Directors who do not meet the New York Stock Exchange ("NYSE") independence standards also make valuable contributions to the Board and to the Company by reason of their experience and wisdom, it is the Board's goal that at least two-thirds of the Directors will be independent under the NYSE's guidelines and those additional guidelines adopted by the Board. 49 The full Board will make affirmative determinations of the independence of each Director. Such determinations shall be made using the standards and processes approved and adopted from time to time by the full Board. Such determinations, as well as the standards and processes applied in making them, will be disclosed to stockholders in accordance with the requirements of the NYSE. The Board has established the following guidelines to assist it in determining Director independence: a. The Director has no material relationship with the Company, either directly or as a partner, shareholder or officer of an organization that has a relationship with the Company; b. the Director, or any member of the Director's family, has not been employed by the Company in the last five years; c. the Director, or any member of the Director's family, has not been employed by, or affiliated with, the Company's auditor in the last five years; d. the Director, or any member of the Director's family, has not been part of an interlocking directorate in the last five years; e. the Director, or any member of the Director's family, does not receive non-director compensation from the Company; f. the Director does not own more than 4.9% of the Company's shares; g. the Director does not serve on more than three other public company boards; and h. the Director does not serve on the board of another E&P company. The following eight Directors are independent under the foregoing guidelines: James R. Baroffio, Edison C. Buchanan, R. Hartwell Gardner, James L. Houghton, Jerry P. Jones, Linda K. Lawson, Charles E. Ramsey, Jr., and Robert A. Solberg. The Company will not make any personal loans or extensions of credit to Directors or executive officers. No Director or family member may provide personal services for compensation to the Company. 5. Size of Board and Selection Process. Approximately one-third of the Directors are elected each year by the stockholders at the annual meeting of stockholders in accordance with their classification. Nominees for Director will be selected on the basis of their integrity, experience, achievements, judgment, intelligence, personal character, ability to make independent analytical inquiries, willingness to devote adequate time to Board duties, and likelihood that he/she will be able to serve on the Board for a sustained period. In connection with the selection of nominees for Director, due consideration will be given to the Board's overall balance of diversity of perspectives, backgrounds and experiences. The Nominating and Corporate Governance Committee will consider any suggestions offered by other Directors or stockholders with respect to potential Directors. Stockholders may propose nominees for consideration by the Nominating and Corporate Governance Committee by submitting the names and supporting information to: Secretary, Pioneer Natural Resources Company, 5205 N. O'Connor Blvd., Suite 1400, Irving, TX 75039. The Board proposes a slate of nominees to the stockholders for election to the Board. The Board also determines the number of Directors on the Board provided that there are at least three. Between annual stockholder meetings, the Board may elect Directors to serve until the next annual meeting for electing that class of Directors. The Board as a whole will be responsible for nominating individuals for election to the Board by the Stockholders, and for filling vacancies on the Board that may occur between annual meetings of the Stockholders. The Nominating and Corporate Governance Committee will be responsible for identifying, screening, and recommending candidates to the entire Board. 50 6. Board Committees. The Board currently has three standing Committees - Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee. The Board may, from time to time, expand the number of standing committees or form ad hoc committees. Each of the Audit, Compensation and Nominating and Corporate Governance committees will be composed entirely of independent Directors and will have a written charter that complies with the requirements of the NYSE. The current charters of these committees will be published on the Pioneer website, and will be mailed to stockholders on written request. The committee chairs report the highlights of their meetings to the full Board following each meeting of the respective committees. The committees normally hold meetings in conjunction with the full Board. The size, membership, and chairs of each committee will be determined by the Board and will comply with NYSE and legal requirements. The membership and chairs of the standing committees may be rotated from time to time to allow Directors to serve on various committees over time and to promote continuity of membership and leadership on each committee. The Nominating and Corporate Governance Committee will provide recommendations to the Board regarding the size, membership, chairs and rotation of committees. The Chairman of the Board ("Chairman") and CEO may participate in any committee meeting except when such participation would present a conflict of interest or, in the case of a Chairman who is also the CEO, when the meeting is a non-management executive session of the committee or Board. 7. Independence of Committee Members. In addition to the requirement that a two-thirds majority of the Board satisfy the independence standards discussed in section 4 above, members of the Audit Committee must also satisfy an additional NYSE independence requirement. Specifically, they may not directly or indirectly receive any compensation from Pioneer other than their Directors' compensation. As a matter of policy, the Board will also apply this additional requirement to members of the Compensation Committee and to members of the Nominating and Corporate Governance Committee. 8. Meetings of Non-Employee Directors. To ensure free and open discussion and communication among the non-employee Directors, these Directors shall meet in executive session at least twice a year with no members of management present. The non-employee Directors may meet without management present at such other times as determined by the Lead Director, or as requested by any non-employee Director. The Lead Director, who is also chairperson of the Nominating and Corporate Governance Committee, shall preside at the executive sessions, unless the non-management Directors determine otherwise. These executive sessions shall also constitute meetings of the Nominating and Corporate Governance Committee, with any non-management Directors who are not members of such committee attending by invitation. 9. Self-Evaluation. The Board conducts an annual self-evaluation to assess its effectiveness. The self-evaluation is conducted on the basis of criteria developed by the Nominating and Corporate Governance Committee and approved by the Board. Each of the Board's committees also conducts an annual self- evaluation. Additionally, the ability of individual Directors to contribute to the Board is assessed in connection with the evaluations and the renomination process. 10. Setting Board Agenda. The Chairman, CEO (if not the Chairman), the Lead Director and Secretary establish the agenda for each Board meeting, taking into account suggestions of other Directors. Directors are encouraged to suggest the inclusion of agenda items or revisions to meeting materials; the Chairman is expected from time to time to ask Directors for their suggestions on these items. Each Director is free to raise at any Board meetings items that are not on the agenda for that meeting. Proposed agendas and materials for meetings are generally delivered well in advance of each Board and committee meeting. In certain cases, due to the sensitive nature of a matter, presentations are provided only at the Board or committee meeting. Directors are expected to review and devote appropriate time to studying Board materials. In addition, the CEO periodically distributes to all Board members items of topical interest relating to Pioneer, its operating environment, and the markets that it serves. 11. Ethics and Conflicts of Interest. Pioneer's Board has adopted a Code of Business Conduct and Ethics applicable to Directors, executive officers and all Pioneer employees. The Board expects Pioneer Directors, as well as officers and employees, to act ethically at all times and to acknowledge annually their 51 adherence to the policies comprising the Company's Code of Business Conduct and Ethics, which is posted on the Company's website. The General Counsel's office and the Audit Committee oversee implementation and compliance with the Code. If a continuing conflict exists and cannot be resolved, the Director should resign. All Directors will recuse themselves from any discussion or decision affecting their personal, business or professional interests. The Board shall resolve any conflict of interest question involving a Director, the CEO or an executive officer, and the CEO and General Counsel shall resolve any conflict of interest issue involving any other officer of the Company. 12. Reporting of Concerns to Non-Employee Directors or the Audit Committee. Anyone who has a concern about Pioneer's conduct, or about the Company's accounting, internal accounting controls or auditing matters, may communicate that concern directly to the Company's General Counsel, Lead Director, or to the Audit Committee. Such communications may be confidential or anonymous, and may be e-mailed, submitted in writing, or reported by phone to special addresses and a toll-free phone number that is published on the Company's website. All such concerns will be forwarded to the appropriate Directors for their review, and will be simultaneously reviewed and addressed by Pioneer's General Counsel's office in the same way that other concerns are addressed by the Company. The status of all outstanding concerns will be reported to the Board on a quarterly basis. The Board or the Audit Committee may direct special treatment, including the retention of outside advisors or counsel, for any concern addressed to them. The Company is prohibited from retaliating or taking any adverse action against anyone for raising or helping to resolve an integrity concern. Pioneer will publish on its website and in its proxy statement a mailing address and an e-mail address for communications with the chairperson of the Nominating and Corporate Governance Committee or the non-management Directors as a group. In addition, Pioneer will publish on its website and in its proxy statement a procedure for communicating with the Audit Committee regarding accounting, internal accounting controls or auditing matters. 13. Compensation of Board. The Compensation Committee shall have the responsibility for recommending to the Board compensation and benefits for non-employee Directors. In discharging this duty, the Compensation Committee shall be guided by three goals: alignment of the long-term interests of stockholders with the Directors' interests and compensation; fairly paying Directors for work required in a company of Pioneer's size and scope; and making the structure of the compensation simple, transparent and easy for stockholders to understand. The Compensation Committee shall annually review non-employee Director compensation and benefits. 14. Succession Plan. The Board shall approve and maintain a succession plan for the CEO and certain senior executives. To assist the Board, the CEO will annually provide the Board with an assessment of senior officers and of their potential to succeed him or her. The CEO will also provide the Board with an assessment of persons considered potential successors to certain senior officers. 15. Annual Compensation Review of Senior Management. The non-employee Directors, in a session chaired by the Lead Director, will undertake a formal evaluation of the CEO annually. The evaluation should be based on objective criteria including but not limited to the performance of Pioneer's businesses and the accomplishment of long-term and strategic objectives. The chairperson of the Nominating and Corporate Governance Committee shall be responsible for reviewing the evaluation with the CEO. The Compensation Committee will then consider the CEO's performance as determined in the evaluation before setting the CEO's salary, bonus and other incentive and equity compensation. The Compensation Committee shall also annually approve the compensation structure for the Company's officers, and shall consider the performance of the Company's executive officers before approving their salary, bonus and other incentive and equity compensation. 16. Access to Senior Management. Directors have complete and open access to the Company's management. In addition, the Company's executive officers routinely attend Board and committee meetings. The Board encourages its executive officers to bring other officers and managers into Board or committee meetings or other scheduled events from time to time to provide additional insight into matters being considered or to expose the Board to individuals with high potential for significant leadership roles in the Company. Additionally, Directors may from time to time meet individually with members of management. Non-employee Directors are encouraged to contact senior managers of the Company without 52 executive officers or the CEO present. Board members use judgment to be sure that this contact is not distracting to the business operation of the Company. Such contact, if in writing, is copied to the CEO. 17. Access to Independent Advisors. The Board and its committees shall have the right at any time to retain independent outside financial, legal or other advisors. 18. Director Orientation. The General Counsel and Secretary's office shall be responsible for providing an orientation for new Directors, and for periodically providing materials or briefing sessions for all Directors on subjects that would assist them in discharging their duties. Each new Director shall, within six months of election to the Board, spend time at corporate headquarters for personal briefing by the executive officers and CEO on the Company's strategic plans, its financial statements, and its key policies and practices. New Directors also receive a comprehensive package of orientation materials. 19. Continuing Education. Directors are encouraged to take advantage of continuing education opportunities that will enhance their ability to fulfill their responsibilities. To facilitate this participation, Pioneer will endeavor to make the Directors aware of Director education programs and will pay the expenses of any Director attending approved Director education programs. In addition, Directors are expected to keep informed about Pioneer and its activities and the industry conditions affecting independent exploration and production companies generally. 20. Stock Ownership. The Board believes that it is important to align the interests of Directors with those of the stockholders and for Directors to hold equity ownership positions in the Company that are meaningful in their individual circumstances. Directors are required to own Pioneer common stock having a value of at least three times their annual retainer. Included in this total are common stock and restricted common stock, but not stock options. Each Director is given three years from the date of initial appointment or election to reach this ownership level. The Nominating and Corporate Governance Committee shall adopt and periodically review a policy with respect to minimum share ownership requirements for Directors. Additionally, the Board believes that a significant portion of Directors' compensation should be made available to them in stock, stock options or other forms of compensation that correlate with the market value of the Company. 21. Evaluation of Corporate Governance Principles. The Nominating and Corporate Governance Committee will review Pioneer's Corporate Governance Principles from time to time as developments or circumstances make review of particular Principles appropriate. The entire Corporate Governance Principles will be reviewed by the Committee not less frequently than every three years. The Nominating and Corporate Governance Committee will report to the full Board for its consideration and adoption any recommendations for additions or amendments to the Principles, as well as the process and results of the full review of the Principles conducted every three years. 22. Confidentiality. The proceedings and deliberations of the Board and its committees shall be confidential. Each Director shall maintain the confidentiality of information received in connection with his or her service as a Director. 53 PIONEER NATURAL RESOURCES COMPANY 5205 North O'Connor Boulevard Suite 1400 Irving, Texas 75039 IMPORTANT NOTICE REGARDING DELIVERY OF SHAREHOLDER DOCUMENTS The Securities and Exchange Commission has enacted rules that allow multiple shareholder accounts with the same last name and the same address the convenience of receiving a single annual report, proxy statement, prospectus or other information statement.
