                                QUORUM AND VOTING

        Voting Stock. The Company has two outstanding classes of securities that
entitle  holders to vote  generally at meetings of the  Company's  stockholders:
common stock, par value $.01 per share; and Special  Preferred Voting Stock, par
value $.01 per share.  A single  share (the "Voting  Share") of Special  Preferred  Voting  Stock (the
"Voting  Share") was issued to Montreal Trust Company of Canada (the  "Trustee")
as trustee  under a Voting  and  Exchange  Trust  Agreement  for the  benefit of
holders of exchangeable shares issued by the Company's wholly- ownedwholly-owned  subsidiary,
Pioneer Natural Resources Canada Inc., in connection with the Company's December
1997 acquisition of Chauvco Resources Ltd. The common stock and the Voting Share
vote together as a single class on all matters except when Delaware law requires
otherwise. Each share of common stock outstanding on the record date is entitled
to one vote.  The Voting  Share is  entitled  to one vote for each  exchangeable
share outstanding on the record date. The Trustee is required to vote the Voting
Share in the manner that holders of exchangeable shares instruct, and to abstain
from voting in proportion to the exchangeable  shares for which the Trustee does
not receive  instructions.  Accordingly,  references to  "stockholders"  in this
Proxy  Statement  include holders of common stock,  the Trustee,  and holders of
exchangeable  shares.  The  procedures  for  holders of  exchangeable  shares to
instruct  the Trustee  about voting at the Annual  Meeting are  explained in the
"Information  Statement for Holders of  Exchangeable  Shares of Pioneer  Natural
Resources  Canada  Inc." that is  enclosed  with this Proxy  Statement  only for
holders of exchangeable shares.

        Record Date. The record date for stockholders  entitled to notice of and
to vote at the Annual Meeting is the close of business on April 3, 2000.March 28, 2001. At the
record  date,  96,269,73696,299,025  shares of  common  stock and one  Voting  Share  were
outstanding and entitled to be voted at the Annual Meeting.  At the record date,
3,568,5621,940,656  exchangeable  shares  were  outstanding  and  entitled to give voting
instructions to the Trustee.  Accordingly,  99,838,29898,239,681  votes are eligible to be
cast at the Annual Meeting.

                                        3






        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 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 two 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  persons for election
as Class IIII  directors  of the  Company  with their terms to expire at the annual
meeting of stockholders in 20032004 when their successors are elected and qualified:

                               Jerry P. Jones
                             Charles E. Ramsey, Jr.R. Hartwell Gardner
                                James L. Houghton

        Both of  these  nominees  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  either 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.

                                    ITEM TWO

                              SELECTION OF AUDITORS

        The Board of Directors has selected Ernst & Young LLP as the auditors of
the  Company  for  2000.2001.  Ernst & Young  LLP  audited  the  Company's  financial
statements for 2000,  1999 and 1998. The 19992000 audit was completed on January 24,29,
2001.

Audit Fees

        The aggregate fees billed by Ernst & Young LLP for professional services
rendered for the audit of the Company's annual financial  statements and reports
on Forms 10-Q for 2000 were $420,000.

Financial Information Systems Design and Implementation Fees

        No services  were  performed  by, and no fees were  incurred to, Ernst &
Young  LLP  in  connection  with  financial   information   systems  design  and
implementation projects for 2000.

All Other Fees

        The aggregate fees for all other services  rendered by Ernst & Young LLP
for 2000 were  $512,228,  comprised  of $68,395 for tax  services,  $332,960 for
internal audit services and $110,873 for other professional services.

        The Company  expects that  representatives  of Ernst & Young LLP will be
present at the Annual Meeting to respond to appropriate  questions and to make a
statement if they desire to do so.

        The report of Ernst & Young LLP on the  Company's  financial  statements
for 2000,  1999 and 1998 did not contain an adverse  opinion or a disclaimer  of
opinion and was not  qualified or modified as to  uncertainty,  audit scope,  or
accounting principles.

        In connection with the audits of the Company's financial  statements for
2000, 1999 and 1998, 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 report.

        The  Board  of  Directors   recommends   that   stockholders   vote  FOR
ratification of the selection of Ernst & Young LLP.

                        DIRECTORS AND EXECUTIVE OFFICERS

(b) These options were granted on August 16, 2000, vest at the rate of one-third each year commencing on the first anniversary of the grant date, and have a term of five years from the date 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 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 shares in footnotes (a) and (b) is determined using the Black-Scholes model. The material assumptions and adjustments incorporated in the Black-Scholes model in estimating the value of the options include the following: o An interest rate of 5.72% for footnote (a) and 5.71% for footnote (b), which represents the interest rate on a U. S. Treasury security with a maturity date corresponding to the expected option term. o Volatility of 50% for footnote (a) and (b) calculated using the lesser of (1) daily stock prices for the 120-day period prior to the grant date, or (2) 50%. 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 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 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 1999,2000, and the value of unexercised stock options as of December 31, 1999.2000.

The Company provides a non-qualified deferred compensation retirement plan for officers and key employees of the Company. Each participant is allowed to contribute up to 25% of base salary. The Company provides a matching contribution of 100% of the participant's contribution limited to the first 10% of the officer's base salary (or 8% of the key employee's base salary). The Company matching contribution vests immediately. Employee Investment Partnerships. From 1987 through 1991, Parker & Parsley formed employee partnership programs in which Mr.Messrs. Sheffield, Withrow, and Kellum participated. In 1992 and 1993 Mr.Messrs. Sheffield, Withrow and Mr. WithrowKellum participated in a Direct Investment PartnershipPartnerships formed to invest in all wells drilled by Parker & Parsley during those years (except in certain circumstances where its participation would impose additional costs to Parker & Parsley). As of December 31, 1999,2000, the aggregate contributions that have been made to the employee partnerships and the Direct Investment Partnerships by Mr.Messrs. Sheffield, Withrow and Mr. WithrowKellum and the aggregate distributions that have been received by them from those partnerships were as follows: Mr. Sheffield contributed $734,955 and received $1,145,680$1,287,280 ($79,555141,550 of which was received during 1999)2000); and Mr. Withrow contributed $142,625 and received $151,437$170,593 ($13,20619,156 of which was received during 1999)2000); and Mr. Kellum contributed $141,709 and received $193,339 ($20,563 of which was received during 2000). During December 2000, the Company acquired 13 of the employee partnerships by merger with Pioneer Natural Resources USA, Inc. ("Pioneer USA"), a wholly-owned subsidiary of the Company. Additionally, during November 2000, the Company exercised its right under the Direct Investment Partnership agreements to purchase each partner's interest in their respective Direct Investment Partnership. More information about these transactions can be found below in "Certain Relationships and Related Transactions." Severance Agreements. On August 8, 1997, theThe Company enteredenters into severance agreements with its officers. Salaries and bonuses are set by the Compensation Committee independent of these agreements, and theagreements. 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 one year. 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. 9 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. COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION Mr. Robert L. Stillwell is a member of the Compensation Committee and is a partner of Baker & Botts, L.L.P., which provided limited legal services to the Company during 1999.2000. The dollar amount of fees that the Company paid to Baker & Botts, L.L.P. during the most recent fiscal year of that law firm did not exceed 5% of that firm's gross revenues. Mr. Stillwell does not serve on the sub-committee of the Compensation Committee that administers the Company's Long-Term Incentive Plan. 11 COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION The Compensation Committee of the Board of Directors (the "Committee") 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 1999,2000, the Committee retained an executive compensation consulting firm ("Hewitt Associates")(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. Stock option awards will continue to be emphasized as part of each executive's compensation package to align stockholder and executive interests. Other critical elements of the Company's compensation and incentive policies provide for: o Base salaries at median levels compared to industry survey information and peer group proxy analysis. o Annual target bonus levels at or slightly above median levels compared to industry survey information and peer group proxy statement analysis. o Annual bonuses that are based on both individual and Company performance. o Long-term incentive award levels that are above median.median levels compared to industry survey information and peer group proxy statement analysis. o Significant stock ownership by management.the Directors and the CEO. To support the commitment to significant stock ownership, the Company's current stock ownership guidelines are as follows: o Non-employee directors - stock value equal to at least three times each director's annual retainer fee.fee o Chairman of the Board and Chief Executive Officer - stock value equal to at least five times base salary. In determining compliance with these guidelines, the Committee considers its expectations of the long term value of the Company's stock, and the current trading levels.levels and stock-based compensation that the directors and CEO hold. Mr. Sheffield and all Directors are in compliance with the ownership guidelines. 10 The Omnibus Budget Reconciliation Act of 1993 ("OBRA93") placed restrictions on the deductibility of executive compensation paid by public companies. Under the restrictions that began to applywere effective in 1994, 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,this law, 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. However, in order to induce certain executive officers of the Company to relocate to the Company's principal executive offices in Irving, Texas, after the merger of Parker & Parsley and Mesa in 1997, the Company made certain relocation reimbursement payments to such officers, which payments were not wholly deductible by the Company because of the compensation limits of OBRA93. 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- TermLong-Term Incentive Plan, (the "Plan"), contributions to the Company's 401(k) retirement plan, contributions to the Company's deferred compensation retirement plan, and miscellaneous 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. 12 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 named executives below the CEO level as a team with diverse duties but with similar authority and responsibility. Hewitt Associates provideshistorically 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 Oil-SecondaryOil- Secondary Index (the "DJ Oil-Secondary Group") reflected in the performance graph set forth below under "Company Performance" below,Performance," 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 named executives, including Mr. Sheffield, using the same methodology. Due to adverse economic conditionsThe 2000 base salaries for the oil and gas industry experienced during 1998, and the desire to reduce the Company's 1999 cost structure duringnamed executive officers as a year of expected low commodity prices,group, including Mr. Sheffield, reduced his 1999 base salarywere identified by 20% to $480,000, and the other named executive officers' base salaries were reduced by 10%. For 1999, Mr. Sheffield's and the other named executives' base salaries were significantly less thanHewitt Associates as being at approximately the 50th percentile even thoughlevel. In establishing the Company normally targets the 50th percentile level for base salary. Effective January 1, 2000, the 1999 salary reduction program expired and base salaries were restored to the 1998 levels. Mr. Sheffield's base salary was restored to $600,000. For 2000, Hewitt Associates determined that merely returningfor the named executive officer's salary to the 1998 level resulted in base salaries below the Company's targeted 50th percentile level. Effectiveofficers effective January 1, 2001, the Committee elected to not commission Hewitt to complete the salary survey but applied a conservative percentage increase of 3% to their 2000 base salary levels. One named executive also received a promotional base salary increase. Mr. Sheffield's base salary was increased by 3% to $638,000,$668,000, which Hewitt has identified asthe Committee believes is at or slightly below the 50th percentile level.percentile. The Committee believes the other named executive officers'officer's base salaries were also restoredare close to the 1998 levels50th percentile. The Committee has retained Hewitt Associates to survey the Company's peer group and increased to approximately the 50th percentile level.report current compensation market data so that 2002 salary adjustments will be based on surveyed market conditions. Annual Bonuses. Each year the Committee setsestablishes a target bonus for each executive based on the rangetarget bonus median levels of theexecutives in similar positions at peer group's bonus targets.group companies. To maintain internal equity, the level of responsibility, scope and complexity of the executive's position are considered. Awards may vary fromThe normal range of awards for the annual incentive bonus plan is between 50% toand 150% of target. For 2000, theThe Committee reducedbelieves the target bonus opportunitylevels for each named executive by 5%. Mr. Sheffield's new target bonus will be slightly below the 50th percentile, and the target bonus for the other named executives will be at approximately the 50th percentile. For 1999, the Committee awarded Mr. Sheffield and the other named executives a cash bonus of 75% of target. In addition tofor 2000 are slightly below the annual bonus award,peer group's median levels. Hewitt Associates will advise the Committee approvedduring 2001 of appropriate target bonus levels to achieve the forgivenessCompany's goal of a $113,204 Company loan to Mr. Dove. As part of his initial hiring package, Mr. Dove received a restricted stock award which vested in August, 1997 due toestablishing target bonus levels that are at or slightly above the merger of Parker & Parsley and MESA. The Company funded the tax liability on the vested stock through a loan 11 because the United States Securities and Exchange Commission ("SEC") rules prevented Mr. Dove from selling the stock without incurring substantial penalties. In February 1999 the Committee forgave the loan when it determined the current valuemedian of the award was less than the tax liability triggered by the merger.Company's peer group. In awarding 19992000 bonuses, the CommitteeCompany reviewed the following criteria that are important to the success of the Company's business plan. -o Growth of Cash Flow per Share -o Operating Cost per BOE -o Debt/Book -o Reserve Replacement -o Growth of Net Value per Share -o Finding & Development Cost per BOE -o Production Growth -o Debt/BOE In determining the named 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 or operational performance criteria. The Committee also 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 discusses the performance of these key executives with Mr. Sheffield. For 2000, the Committee awarded Mr. Sheffield and the other named executives cash bonuses above the target bonus levels. Specific Company performance which resulted in bonus payouts above target for 2000 included: o Stock price increase of 120% o Base operating costs of $2.72 per BOE o Finding costs of $4.66 per BOE o Reserve replacement of 167% 13 o Return on equity 18.1% o General & administrative cost of $.76 per BOE o Debt reduction of $167,000,000 Long-term Incentives. A significant portion of the named executive officers' total compensation is comprised of long-term incentive awards, which are intended to align executive management's interests in long- termlong-term growth and success more closely with the interests of the Company's stockholders. The Committee has determined that annual stock option awards should be the primary method to award long-term incentives. To provide an averaging effect for the stock option exercise prices, the Committee has elected to make semiannual stock option awards of approximately 50% of annual grant levels. The number of options granted to Mr. Sheffield in 19992000 was determined by a comparison of option grants made to the CEO's of peer group companies. The other named executive officers were reviewed as a team. The level of options awarded to each named executive was determined by comparing awards granted to peer company executives holding similar positions, and their individual award levels were averaged to determine the actual grants. The award levels were not influenced by the stock holdings of the executives. The Company has historically held to the philosophy of awarding long-term incentives that are above market averages. Hewitt Associates concluded the 1999 stock option awards for the Company's named executive officers, including Mr. Sheffield, are now below the 50th percentile among the survey group. For 1999,2000, Mr. Sheffield was awarded 90,000120,000 stock options, which, according to Hewitt Associates,options. The Committee believes this award level placed Mr. Sheffield belowat approximately the 50th percentile for long-termlong- term incentive awards for chief executive officers among the survey group. In December 1998, the Company received information that an investment fund group had acquired beneficial ownership of more than 20% of the common stock. Pursuant to the provisions of the Plan, if a third party acquires 20% or more of the common stock, certain change in control provisions are triggered. In December 1998, the Committee determined that a change in control had occurred under the provisions of the Plan, effective September 30, 1998. Consequently, all stock option awards granted under the Plan from inception in August 1997 through September 30, 1998, were immediately vested, and the restrictions on restricted stock awards were removed. The Plan has been amended to increase the third party ownership to 40% to trigger the change in control provisions. In summary, the Company believes a significant portion of executive compensation should be variable and performance-based so that an executive's total compensation is linked to the performance of the individual, the Company and its stock price. The majority of the named executive officers' total compensation is variable, at-risk compensation. This structure allows the Company to administer overall compensation that rises or falls based on the Company's performance and to maintain a balance between the Company's short-term and long-term objectives.

Stillwell 12AUDIT 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. 14 In performing its oversight role, the Audit Committee has considered 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, Independence Discussions 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 Audit 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, 2000, for filing with the Securities and Exchange Commission. The committee and the board have also recommended the selection of the Company's independent auditors. The members of the Audit 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 Audit 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 Audit 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.

Jones 15 COMPANY PERFORMANCE The following graph and chart compare the Company's cumulative total stockholder return on common stock during the period from December 31, 19941995 to December 31, 1999,2000, with cumulative total stockholder return during the same period for the DJ Oil-Secondary Group and the Standard &and Poor's 500 Index.Index as prescribed by SEC rules. The Company's cumulative total stockholder return for the period from December 31, 19941995 to December 31, 19992000 consists of Parker & Parsley's operating results prior to August 8, 1997 and the Company's operating results beginning August 8, 1997. After the merger of Parker & Parsley and Mesa in 1997, the Company began using the DJ Oil-Secondary to compare its performance because several members of the Company's peer group use that index to simplify the evaluation of company performance and because the DJ Oil-Secondary is more readily available to the public for comparison purposes. The graph and chart show the value, at December 31 in each of 1995, 1996, 1997, 1998, 1999 and 19992000 of $100 invested at December 31, 1994,1995, and assume the reinvestment of all dividends.

In accordance with the terms of the partnership agreements and the related tax partnership agreements of the affiliated partnerships, the Company participated in the activities of the sponsored partnerships on a promoted basis. In 1992, the Company discontinued sponsoring public and private oil and gas development drilling partnerships, income partnerships and incomeaffiliated employee partnerships. In December 2000, the Company received the approval of the partners of 13 employee partnerships to merge with Pioneer USA for a purchase price of $2.0 million. Of the total purchase price, $317,055 was paid to current Company employees, of which amount $138,899, $22,886 and $48,972 were paid to Mr. Sheffield, Mr. Withrow and Mr. Kellum, respectively. Additionally, during 2000 the Company purchased all of the direct oil and gas interests held by Mr. Sheffield for $195,133. During each of 1994, 1993 and 1992, the Company formed a Direct Investment Partnership for the purpose of permitting selected key employees to invest directly, on an unpromoted basis, in wells that the Company drills.drilled. The partners in the Direct Investment Partnerships formed in 1994, 1993 and 1992 paypaid and receivereceived approximately .337%, 1.5375% and 1.865%, respectively, of the costs and revenues attributable to the Company's interest in the wells in which each such Direct Investment Partnership participates. The Company discontinued the formation of Direct Investment Partnerships in 1995. In November 2000, the Company exercised its right under the Direct Investment Partnership agreements to purchase each partner's interest in their respective Direct Investment Partnership. The Company paid $4.3 million to complete the purchases. Current employees of the Company were partners in the Direct Investment Partnerships and received $886,512 of the proceeds from the purchases, of which amount $416,364, $117,578 and $77,204 were paid to Mr. Sheffield, Mr. Withrow and Mr. Kellum, respectively. 18 The Company, through a wholly-owned subsidiary, serves as operator of properties in which it and its affiliated partnerships have an interest. Accordingly, the Company receives producing well overhead, drilling well overhead and other fees related to the operation of the properties. The affiliated partnerships also reimburse the Company for their allocated share of general and administrative charges. Effective January 1, 1999, the Company entered into an agreement with Rainwater, Inc., the former general partner of DNR that Mr. Rainwater wholly owns, modifying certain terms of a prior agreement between DNR and Mesa, which was assumed by the Company upon consummation of the merger between Parker & Parsley and Mesa. Pursuant to the terms of this agreement, as modified, the Company will pay Rainwater, Inc. $300,000 per year and reimburse Rainwater, Inc. for certain expenses in consideration of the provision of certain consulting and financial analysis services to the Company by Rainwater, Inc. and its representatives. On June 29, 1999, the Company completed the sale of certain United States oil and gas producing properties, gas plants and other assets primarily located in the Gulf Coast, Mid Continent and Permian Basin to Prize Energy Corp. ("Prize"). The sale of these assets was initiated through an auction process. The Board of Directors of Prize includes Mr. Philip P. Smith, its Chief Executive Officer, Mr. Kenneth A. Hersh, and Mr. Lon C. Kile, its President and Chief Operating Officer. Mr. Hersh, through his association with Natural Gas Partners V, L.P., owned or controlled approximately 88% of Prize. Messrs. Smith and Kile owned or controlled approximately 10.5% and .5% of Prize respectively. Because Mr. Smith and Mr. Hersh were members of the Board of Directors of the Company and Mr. Kile was an Executive Vice President of the Company prior to initiating the auction process, supervision of the sale process was placed under the direction of a special independent committee (comprised of outside directors unrelated to Prize) of the Company's Board of Directors. The independent committee reviewed and considered all offers presented to the Company for the purchase of the assets acquired by Prize. The Prize offer was approved by the special independent committee as being the best offer presented. Following approval of the Prize offer by the special independent committee, Messrs. Smith, Hersh and Kile resigned their positions with the Company. In accordance with the terms of the Prize purchase and sale agreement, the Company received net sales proceeds of $245.0 million, comprised of $215.0 million of cash and 2,307.693 shares of six percent convertible preferred stock ("Prize Preferred") having a liquidation preference and fair value of $30.0 million. AsPrior to February 9, 2000, Prize was a resultclosely held, non-public entity and the fair market value of the Prize Preferred was not readily determinable. On February 9, 2000, the common stock of Prize merging with Vista Energy Resources, Inc.,("Prize Common") began to publicly trade on the American Stock Exchange. At that time, the Company's investment in Prize's six percent convertible preferred stockPrize Preferred was exchanged for 4,018,1613,984,197 shares of Prize Series A convertible preferred stock6% Convertible Preferred Stock ("Prize SeriesSenior A Preferred"). TheOn March 31, 2000, the Company and Prize Series A Preferred provides for six percent annual dividend payments, payable quarterly in additional equityconverted the Company's 3,984,197 shares of Prize through 2001. Subsequent to 2001, Prize has the option of paying the quarterly dividends on the Prize Series A Preferred to 3,984,197 shares of Prize Common, received cash in equitylieu of 33,964 shares or cash. Each share of the Prize Series A Preferred may, at the option ofpreferred in-kind dividends and the Company be converted into one share ofsold to Prize common stock, subject to certain anti-dilution adjustments. The Company has entered into an agreement with Prize to sell effective March 31, 2000, 1,380,4461,346,482 shares of the Prize Series A Preferred back toCommon for a combined cash total of $18.6 million. During 2000, the Company sold an additional 2,024,500 shares of Prize Common in the open market for $18,636,021. Pioneer and Prize have also agreed to convert$41.1 million. The Company recognized aggregate net gains from the remaining sharesdispositions of the Prize Series A Preferred to 2,637,715Common of $34.3 million during 2000. The fair market value of the Company's remaining investment in 613,215 shares of Prize common 15 stock. If these transactions are completedCommon as planned, the Company's ownership of outstanding Prize common and preferred voting shares would decline from 27.4% to 19.9% and Mr. Sheffield and Mr. Withrow will resign from the Prize Board of Directors. In February 1999, the Company, after approval from the Compensation Committee, forgave an August, 1997 loan to Mr. Dove in the amount of $113,204, which funded the tax liability resulting from vesting of his restricted stock in August 1997 in the merger of Parker & Parsley and MESA.December 31, 2000 was $12.7 million.
