For other items of business that come before the meeting, the persons named as proxies will vote in accordance with their best judgment. WHO CAN VOTE If you are listed on our stockholder register as a holder of common stock at the close of business on March 22, 1999, you are entitled to vote your shares at the annual stockholders' meeting. March 22, 1999 is the record date. Anyone listed on this register on the record date is called a holder of record on that date. There were 97,405,090 shares of common stock outstanding on March 22, 1999. Each share is entitled to one vote, but you will not be entitled to vote any fractional shares you hold. The approximate date on which this proxy statement and the proxy card were first sent to stockholders was March 29, 1999. SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS March 22, 1999 is the date when we determined the identity of the holders of record of our common stock entitled to vote at the 1999 annual stockholders' meeting. On March 22, 1999, the only person known to us to own more than 5 percent of our common stock is: Amount and Nature of Name and Address Beneficial Percent Title of Class of Beneficial Owner Ownership of Class -------------- ------------------- ---------- -------- Common Stock.................. Atlantic Richfield Company 80,000,001 82.1% 515 South Flower Street Los Angeles, California 90071 ARCO (Atlantic Richfield Company) has both the voting power and the power to dispose of these shares. It does not share this power with any other person. ARCO is able, acting alone, to elect the entire board of directors of Vastar and to approve any action requiring stockholder approval. ARCO's level of ownership of our common stock precludes any acquisition of control of Vastar, unless favored by ARCO. ARCO has informed us that it intends to vote its shares in favor of the nine nominees to the board of directors and for the approval of PricewaterhouseCoopers LLP as independent auditors for the year 1999. 1 SECURITY OWNERSHIP OF MANAGEMENT The table below lists the number of shares of Vastar common stock and ARCO common stock beneficially owned by the following persons: (i) Each of our directors; (ii) Our President and Chief Executive Officer; (iii) The four highest-paid executive officers (other than our President and Chief Executive Officer); and (iv) All of Vastar's directors and executive officers as a group. The date we chose to determine beneficial ownership was February 1, 1999. Beneficial ownership of common stock by a person as of a particular date means common stock directly or indirectly owned by that person on the date and common stock which that person has the right to acquire within 60 days of the date. On February 1, 1999, no Vastar director or executive officer beneficially owned more than 1 percent of Vastar's common stock or more than 1 percent of any other class of equity securities of Vastar or ARCO. In addition, all of the equity securities owned by our directors and officers as a group did not exceed 1 percent of any class of equity securities of Vastar or ARCO. Each individual has sole voting and investment power over the shares indicated.

The following table shows the stock options granted to Mr. Davidson and the four other highest-paid executive officers, other than Mr. Davidson, for their 1998 performance.

Each stock option is accompanied by a tax withholding right which will allow us to withhold a portion of the common stock due to an executive on the exercise of an option to pay any taxes which may be due. If the executive terminates his or her employment for reasons other than retirement or death, stock options held for less than one year are cancelled, and stock options which are exercisable on the date of termination of employment and which have been held for more than one year are exercisable for 90 days after termination of employment, unless we determine otherwise. All stock options automatically vest and are exercisable if a change of control of Vastar occurs. The definition of a change of control is summarized in the material under the heading "Change of Control Arrangements" in this proxy statement. The last two columns on the right of the table present the hypothetical future value of Vastar common stock which might be received on the exercise of the stock options, net of the option's exercise price. The hypothetical value is based on the assumption that the market price of our common stock will appreciate at a 5 and 10 percent compound annual rate over the ten-year term of the options. The market price of our stock on the March 2, 1999 grant date was $39.8125, and the future price of our stock using these same 5 and 10 percent compounding over ten years would be $64.8504 and $103.2634.

You can find base salary and bonuses in columns (c) and (d) of the Summary Compensation Table which appears previously in this proxy statement. The amounts shown above are based on the following assumptions: . That the participant retires on January 1, 1999; and . That the retirement benefit will be paid for the life of the participant with a guaranteed minimum payment period of 60 months. The amount of the retirement benefit would change if the payment were made under any other form permitted by the retirement plans or if the participant's retirement occurs after January 1, 1999. The benefits shown are not subject to deduction for Social Security benefits or other offset amounts. As of December 31, 1998, the credited years of service under these plans for the following executive officers were: . Mr. Davidson--26 years, 7 months; . Mr. Shapiro--21 years, 6 months; . Mr. Gobe--1 year, 8 months; . Mr. Strode--1 year, 11 months; and . Mr. Hoppe--22 years, 4 months. 10 PERFORMANCE GRAPH Comparison of Cumulative Total Return Since Initial Public Offering This performance graph compares our cumulative total stockholder return with the cumulative total stockholder return of the Standard & Poor's 500 Stock Index and our peer group. Our peer group was selected by us and consists of Vastar and the following companies: Anadarko Petroleum Corporation; Apache Corporation; Burlington Resources, Inc.; Enron Oil & Gas Company; Noble Affiliates, Inc.; Oryx Energy Company; Pioneer Natural Resources Company; and Union Pacific Resources Group, Inc. The comparison begins on June 27, 1994, the date of our initial public offering: [GRAPH APPEARS HERE] June 27, December 31, December 31, December 31, December 31, December 31, Year 1994 1994 1995 1996 1997 1998 ---- -------- ------------ ------------ ------------ ------------ ------------ Vastar Resources, Inc... $100.00 $ 89.10 $114.89 $138.67 $131.57 $160.14 S&P 500 Index........... $100.00 $102.70 $137.70 $167.10 $222.90 $286.60 Peer Group.............. $100.00 $ 81.04 $ 98.97 $125.06 $111.03 $ 74.11 The data represented on the table assumes an initial investment of $100 and reinvestment of all dividends. The peer group companies are weighted for market capitalization as of the beginning of each period. 11 CHANGE OF CONTROL ARRANGEMENTS The Board of Directors has adopted certain arrangements that apply generally to employees, including Mr. Davidson and the other top four highest-paid executive officers of Vastar, which become operative only upon a change of control of Vastar.* If a change of control occurs, all unvested stock options granted to Vastar's officers and employees under our long-term incentive plan will become immediately vested and exercisable. Also, if an eligible employee is terminated under specified conditions within two years following a change of control, the employee will be entitled to severance and welfare benefits. Under the severance program, Messrs. Davidson, Gobe, Shapiro and Strode would receive (i) three times an amount equal to the sum of their current base salary plus the average of their last three years' bonus and (ii) for the calendar year in which termination occurs, an amount equal to 50 percent of their target bonus for that year, if termination occurs in the first six months of the year, or 100 percent of their target bonus for that year, if termination occurs within the second six months of the year. These officers would also receive payment from us for the amount of any excise tax liability imposed pursuant to Internal Revenue Code Section 4999 with respect to any benefits paid in connection with a change of control. Mr. Hoppe would receive (i) two times an amount equal to the sum of his current base salary plus the average of his last three years' bonus and (ii) for the calendar year in which termination occurs, an amount equal to 50 percent of his target bonus for that year, if termination occurs within the first six months of the year, or 100 percent of his target bonus for that year, if termination occurs within the second six months of the year. Messrs. Davidson, Gobe, Shapiro and Strode would also receive welfare benefit coverage upon termination of employment within two years of a change of control under the Vastar-sponsored health, dental and life insurance plans for 36 months. Under this program, Mr. Hoppe would receive 24 months of coverage. One important limitation to receipt of the above-described severance, health, dental and life insurance benefits is that in the event ARCO initiates a tender offer for all or substantially all of our common stock or otherwise attains an ownership interest in Vastar of more than 85 percent, our officers or employees would not be entitled to these benefits and instead would receive such benefits, if any, as may be determined by ARCO. However, with respect to Messrs. Davidson and Shapiro, under an agreement with ARCO this limitation does not apply. As a result, they would be entitled to the benefits as described above, including severance benefits related to a constructive termination. - -------- * A "Change of Control" is defined as any one of six events: (i) The Incumbent Directors (individuals who, as of March 5, 1998, constitute our board of directors and directors who are recommended or approved by a majority of the then-Incumbent Directors) cease for any reason to constitute a majority of our board of directors at the end of any 12-month period; (ii) Consummation of a merger, reorganization or sale of substantially all of our assets, except: (A) when all or substantially all of our stockholders prior to the transaction retain more than a 60 percent ownership of the resulting entity in substantially the same proportions as their ownership prior to the transaction; (B) there is no new 20 percent (or larger percent) stockholder; and (C) at least a majority of the board of directors of the resulting entity were Incumbent Directors; (iii) ARCO reduces its ownership in Vastar below 50 percent and another entity acquires 20 percent or more of Vastar; (iv) ARCO initiates a tender offer for all or substantially all of our common stock or otherwise attains an ownership interest in Vastar of more than 85 percent; (v) our stockholders approve a complete liquidation or dissolution of Vastar; or (vi) a change of control of ARCO occurs as defined in the ARCO 1985 Executive Long-Term Incentive Plan. 12 A change of control under ARCO's 1985 Long-Term Incentive Plan is defined as any one of four events: (1) any person or group (other than ARCO or its benefit plans) acquires 25 percent of ARCO's then-outstanding voting securities other than pursuant to an acquisition from ARCO of up to 40% that is approved by ARCO's board of directors; (2) Incumbent ARCO Directors (directors as of July 28, 1997 and directors recommended or approved by a majority of then-Incumbent ARCO Directors) no longer comprise a majority of the board; (3) shareholder approval of a merger, reorganization or sale of substantially all ARCO's assets, provided that if such shareholders constitute over 60% of the shareholders of the resulting entity and Incumbent ARCO Directors comprise a majority of the board of directors of, and no person owns 25% or more of the resulting entity, then such event will not be deemed a change of control; and (4) shareholder approval of a plan of complete liquidation of ARCO. The above definitions are summaries. Reference is made to our long-term incentive plan filed with the SEC as Appendix A to our 1998 Proxy Statement for the complete text and the discussion of the plan in the 1998 Proxy Statement. 13 COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION The compensation committee and the compensation subcommittee of the board of directors administer Vastar's compensation programs. The compensation committee is composed of Mr. Wiley, Chair, and Messrs. Dallas, LeVine and Schulte. None of these committee members are officers or employees of Vastar. Messrs. Wiley and Dallas are officers and employees of ARCO. ARCO owns 82.1 percent of Vastar's common stock. The compensation subcommittee is composed of Mr. LeVine, Chair, and Mr. Schulte. These subcommittee members are not officers or employees of ARCO or Vastar. The compensation committee administers the annual incentive plan and reviews and approves other forms of executive compensation and benefits. The compensation subcommittee administers the executive long-term incentive plan. The words "we" and "our" in this report on executive compensation refer to the compensation committee or compensation subcommittee as appropriate. Compensation Philosophy The compensation committee's executive compensation goal is to provide competitive levels of compensation to attract, motivate and retain talented executives. The committee's compensation philosophy is that Vastar's best interests are served if the interests and performance of our executive officers are aligned with the interests of our stockholders by linking a significant portion of each executive officer's compensation directly to Vastar's performance. In its deliberations, the compensation committee reviewed the compensation practices and the financial and operational performance of a number of publicly traded companies. These companies are primarily in the oil and gas industry and are called the market comparison companies in this report. The compensation committee used the smaller group of peer group companies identified in the performance graph on page 11 to calculate the formula components of the annual incentive plan and used the larger group of market comparison companies for its other compensation benchmarking analyses. In our analysis, the compensation committee and the compensation subcommittee compared Vastar's performance with the performance of the market comparison companies and the peer group companies. We also considered the individual performance of each executive officer and the other factors described below. An outside compensation consultant reviewed our executive compensation program. The consultant assessed executive compensation and financial and operational performance as compared to the peer group and market comparison companies. The consultant concluded that our executive compensation program was consistent with our philosophy of paying executives above the median when Vastar achieves above-average performance. Components of Executive Compensation Base Salaries The compensation committee targets base salaries slightly above the median of the market comparison companies at levels the committee considers appropriate in light of the job responsibilities associated with each executive officer's position. The committee reviews base salaries every year to determine if an adjustment is appropriate in light of the executive officer's responsibilities, his or her individual performance and the competitive salaries for similar positions within market comparison companies. Annual Incentive Plan Awards The purpose of the annual incentive plan is to motivate and reward key employees based on Vastar and individual performance. Under the plan, cash award opportunities vary by individual 14 position and are initially set as a percentage of base salary. This percentage for each executive officer is determined using median bonus award levels for similar positions at market comparison companies. The amount a particular officer ultimately earns depends on the outcome of an analysis which has the following two equally weighted components: . Formula component--a quantitative formula of four specific financial and operational measures of Vastar's performance; and . Discretionary component--an analysis based on other financial and operational performance criteria, Vastar's overall performance and individual performance. The formula component uses four measures of Vastar's performance, weighted equally: . Vastar's operating costs per thousand cubic feet equivalent of its production, compared to its peer group companies; . Vastar's ratio of discretionary cash flow to net revenue, compared to its peer group companies; . Vastar's reserve replacement ratio averaged over a three-year period, compared to pre-determined targets set by the compensation committee; and . Vastar's reserve replacement cost averaged over a three-year period, compared to pre-determined targets set by the compensation committee. At the beginning of each year, the compensation committee sets threshold, target and stretch performance criteria for each measure. Under the formula component, Vastar's 1998 performance met or exceeded the stretch performance criteria set by the compensation committee for the operating cost, discretionary cash flow to net revenue and reserve replacement ratio measures and was above threshold performance criteria for the reserve replacement costs measure. Under the discretionary component the compensation committee considered the following other matters: . Vastar's total shareholder return compared to the total shareholder return of the peer group companies; . Vastar's cost management efforts; . Successful completion of a large acquisition of producing oil and gas properties in the Gulf of Mexico; . Vastar's overall performance compared to its peer group companies; . Other standardized measures of oil and gas company performance, such as cash flow, net income, oil and gas production, exploration performance and acquisition activity; and . Each executive's individual performance. The compensation committee did not apply any relative weight to these factors or use any specific quantitative formula in its analysis of the discretionary component. Executive Long-Term Incentive Plan Awards The compensation subcommittee administers the executive long-term incentive plan. This plan provides for the award of stock options to Vastar's executive officers and other key employees. The compensation subcommittee believes stock options align the interests of employees and stockholders by providing value to the executive officers only through stock price appreciation. The compensation subcommittee makes final decisions on stock option awards in the first quarter of each year. The subcommittee made grants to Vastar's executive officers on March 2, 1999 after first considering: 15 . Vastar's financial and operational performance compared to the market comparison companies and the peer group; . Each executive's position and responsibilities compared to similar positions within Vastar and at other similar companies; and . Each executive's individual performance. The compensation subcommittee did not apply any relative weight to these performance factors or use any specific quantitative formulas to arrive at stock option award decisions. Next, the compensation subcommittee compares each executive officer's total cash compensation relative to similar positions at market comparison companies. Then a stock option award is granted so that the value of the executive's total cash and noncash compensation will be above the median of the market comparison companies in years when Vastar achieves above-average performance. Chief Executive Officer Compensation Charles D. Davidson was Vastar's Chief Executive Officer in 1998. In determining Mr. Davidson's 1998 compensation, the compensation committee and compensation subcommittee applied the methodology for determining compensation described above. The compensation committee and the compensation subcommittee recognized Mr. Davidson's substantial accomplishments in 1998, including: . The replacement of oil and gas reserves equal to 215 percent of Vastar's 1998 production; . Successful implementation of a deepwater exploration program and Vastar's first deepwater discovery on the King prospect; . Successful completion of a large acquisition of producing oil and gas properties in the Gulf of Mexico; and . A 1998 total shareholder return of approximately 22 percent and an average annual total shareholder return since Vastar's initial public offering in 1994 of approximately 11 percent. These percentages placed Vastar first among its peer group in both instances and were achieved despite significant decreases in commodity prices in 1998. Based on this analysis, the compensation committee or compensation subcommittee implemented the following compensation program for Mr. Davidson: . Mr. Davidson's annual base salary was adjusted from $380,000 to $420,000 in December 1998 to remain competitive with salaries at the market comparison companies. Mr. Davidson's salary is still slightly below the median for chief executive officers at market comparison companies. . An annual incentive plan award of $364,000 was approved on March 2, 1999 for Mr. Davidson's 1998 performance. This award is higher than his award in 1998 and reflects Vastar's strong financial and operational performance and Mr. Davidson's other accomplishments in 1998. This award was above the median for chief executive officers at market comparison companies. . Mr. Davidson was awarded 60,530 stock options on March 2, 1999. This award puts Mr. Davidson's total compensation at approximately the 60th percentile for similar positions at market comparison companies. The grant was intended to reward him for his achievements in 1998 and puts an increased portion of his total compensation at risk. The compensation committee intends to continue to increase Mr. Davidson's total compensation over time so that his total compensation will approximate the 75th percentile of the market comparison companies in years when Vastar achieves above-average performance. 16 The compensation committee and compensation subcommittee oversee the compensation program for Vastar's other executive officers. Base salaries were increased slightly for certain officers to reflect changing market conditions. Stock option awards and cash bonus awards were granted so that total compensation for these officers averaged near the 70th percentile of the market comparison companies. In 1998, the compensation committee also approved the change of control arrangements described on page 12 of this proxy statement. The compensation committee believes that Vastar's best interest is served when executive officers are not distracted by personal financial concerns in the event a change of control were to occur. Deductible Compensation Limitation Under Section 162(m) of the Internal Revenue Code, publicly traded companies may not receive a tax deduction on compensation in excess of $1 million paid to their chief executive officer and the four other highest compensated officers, unless the compensation meets certain requirements. One of these requirements is that stock option grants be made by "independent" directors. This is the reason Vastar's stock options are granted by the compensation subcommittee which is composed of persons who are not officers or employees of Vastar or ARCO. Our stock option awards under the long-term incentive plan comply with Section 162(m) requirements, allowing Vastar to deduct compensation paid to these officers with such awards when calculating our federal income taxes. Although performance-based, our annual incentive plan is not structured to meet the requirements of Section 162(m). Michael E. Wiley, Chair Terry G. Dallas Robert C. LeVine William D. Schulte 17 BOARD OF DIRECTORS Directors' Meetings The annual meeting of the board of directors takes place each year on the same day as the annual stockholders' meeting. At the annual directors' meeting, the board elects and appoints officers, adopts any necessary organizational resolutions to direct the conduct of Vastar's business and transacts any other necessary business. Regular meetings of the board occur at predetermined times which are set by the board. Also, special meetings may be called by the chairman of the board, the president or a majority of the directors. Our bylaws permit the board to take action without a meeting if all members give written consent. The board of directors held six meetings in 1998. Executive Committee The executive committee has and may exercise all the authority of the board of directors in the management of the business of Vastar in the interim between meetings of the board of directors, except that the full board must review and take board action with respect to any matter which requires stockholder approval under Delaware law. The executive committee held one meeting in 1998. The executive committee consists of Mr. Wiley, Chair, Mrs. Knowles and Messrs. Davidson and Shapiro. Audit Committee The objectives of the audit committee are: . To assist the board of directors in fulfilling its fiduciary responsibilities relating to our financial reporting standards and practices; . To determine the adequacy of, and promote continued emphasis on, managerial and financial control systems; . To maintain open, continuing and direct communication between the board of directors, our independent public accountants and our internal auditors; and . To initiate special investigations, as warranted. At least once a year, the audit committee also reviews the terms of all material agreements between Vastar and ARCO to assure that these agreements, taken as a whole, are fair to Vastar and its stockholders. The independent accountants and the internal auditors have full and free access to the audit committee and meet with the committee, with and without management being present, to discuss all appropriate matters. No member of the audit committee is an officer or employee of Vastar or ARCO. The audit committee held three meetings in 1998. The audit committee consists of Mr. Schulte, Chair, and Messrs. Callison and LeVine. Compensation Committee and Compensation Subcommittee The compensation committee reviews and approves employee compensation plans and other benefits as it deems advisable. When appropriate, the compensation committee makes recommendations on management succession plans to the Board. The compensation subcommittee administers our long-term incentive plan under which stock options are granted to officers and employees. No member of the compensation committee is an employee of Vastar. No member of the compensation subcommittee is an employee of Vastar or ARCO. No member of either committee is eligible to participate in any benefit plan administered by the committees except that Mr. Wiley holds 350,403 stock options granted to him under the long-term incentive plan when he was an officer and employee of Vastar and participates in other Vastar benefit plans as a former officer and employee of Vastar. At the time he received these benefits he was not a member of the compensation committee or the compensation subcommittee. Members of the compensation committee and the compensation subcommittee who are not employees of Vastar or ARCO participate in a retirement plan, a stock option plan and a deferral plan specifically established for these nonemployee directors. The 18 compensation committee held five meetings in 1998. The compensation subcommittee held two meetings in 1998. The compensation committee consists of Mr. Wiley, Chair, and Messrs. Dallas, LeVine and Schulte. The compensation subcommittee consists of Mr. LeVine, Chair, and Mr. Schulte. Environment, Health and Safety Committee The environment, health and safety committee reviews and assesses our policies, procedures and practices relating to: . The protection of the environment and the health and safety of employees, customers, contractors and the public; . Compliance with applicable environmental, health and safety laws and regulations; and . The development of environmental, health and safety goals and objectives. When appropriate, this committee makes recommendations on these policies, procedures and practices to the board. The environment, health and safety committee held three meetings in 1998. The environment, health and safety committee consists of Mr. Callison, Chair, and Mr. Davidson. Finance Committee The finance committee reviews and makes recommendations to the Board on: . Proposals to issue securities to the public; . Commercial borrowing, other than financing relating to specific projects; . Our capital structure; . Our dividend policy; and . Other projects, proposals and activities submitted to the finance committee by the board. The finance committee held two meetings in 1998. The finance committee consists of Mrs. Knowles, Chair, and Messrs. Dallas and Shapiro. Nominating Committee The nominating committee considers and makes recommendations to the board on the: . Number of directors on the board; . Nominees for board membership; and . Election, tenure and retirement of directors. The nominating committee also considers nominees recommended by stockholders. If you have a recommendation, you may submit it to the nominating committee to our address indicated on the first page of this proxy statement addressed to the attention of our corporate secretary. The nominating committee held one meeting in 1998. The nominating committee consists of Mr. Wiley, Chair, and Messrs. Davidson, LeVine and Shapiro. Compensation of Directors Directors' Fees Directors who are employees of Vastar or ARCO do not receive fees or additional compensation for service as members of the board or any board committee. Directors who are not officers or 19 employees of Vastar or ARCO receive an annual retainer of $25,000, plus $1,000 for each board or committee meeting attended, and receive reimbursement for travel and other related expenses incurred in attending such meetings. In addition, each of these directors who serves as a committee chair receives an additional $5,000 per year. Director status does not entitle a person to participate in our employee stock option or other employee benefit plan programs. Vastar officers who are directors are eligible to participate in these programs as a result of their status as Vastar officers and employees. Directors who are not officers or employees of Vastar or ARCO may participate in the plans described below which are administered by director plan committees selected by the board of directors. The members of these director plan committees are not members of the board of directors. Stock Option Plan for Outside Directors This plan provides that each newly elected director who is not a Vastar or ARCO officer or employee will be granted ten-year nonqualified stock options to purchase 5,000 shares of common stock. For directors who were elected prior to our initial public offering, which was completed in 1994, the exercise price for these options is $28.00, which was the initial public offering price for our common stock. For directors elected after our initial public offering the exercise price is the fair market value of common stock on their election date. The total number of shares of common stock that can be issued under this plan is 75,000. No stock options may be granted under the plan after December 31, 2004. Deferral Plan for Outside Directors This plan permits directors who are not Vastar or ARCO officers or employees to defer up to 100 percent of their annual retainer and board meeting fees and any committee chair and committee meeting fees. Interest accrued in 1998 on deferrals made under the plan totaled $16,919 for Mr. LeVine and $12,938 for Mr. Callison. Mr. Schulte did not maintain a deferral account under the plan during 1998. Retirement Plan for Outside Directors Under this plan, directors who are not Vastar or ARCO officers or employees and who have completed 36 months of service as a member of the board are eligible to receive a retirement benefit. The benefit is payable at age 65 or on retirement from the board of directors, whichever is later. The normal form of this benefit is a monthly allowance equal to one-twelfth of the director's annual retainer. After retirement, this benefit will be paid to the director for the same number of months as the director served on the board. However, directors who have served for 180 or more months prior to retirement are entitled to this monthly benefit for life. A death benefit equal to 50 percent of the director's accrued benefit, with a maximum of 180 months, is payable to a deceased director's designated beneficiary. RELATIONSHIPS AND RELATED TRANSACTIONS WITH ARCO We have entered into a number of agreements and have various other relationships with ARCO. ARCO owns 80,000,001 shares, approximately 82.1 percent of our common stock. The discussion below describes the material relationships and agreements between the two companies. Compensation Committee Interlocks and Insider Participation The members of our compensation committee are Mr. Wiley, Chair, and Messrs. Dallas, LeVine and Schulte. The members of our compensation subcommittee are Mr. LeVine, Chair, and Mr. Schulte. Except for Mr. Wiley, none of these persons are or have ever been officers or employees of Vastar. Mr. Wiley is currently the President and Chief Operating Officer of ARCO. In addition, Mr. Wiley, as Chairman of the Board of Vastar, is an ex officio officer of Vastar under its bylaws and was Vastar's 20 President and Chief Executive Officer until he resigned on March 31, 1997. Mr. Wiley receives no compensation from Vastar and is not eligible to participate in any of our benefit plans as a result of his serving as Chairman of the Board. Mr. Wiley holds 350,403 stock options granted to him under the long- term incentive plan when he was an officer and employee of Vastar and participates in other Vastar benefit plans as a former officer and employee of Vastar. At the time he received these benefits, he was not a member of the compensation committee or the compensation subcommittee. Mr. Dallas, one of our directors, is a Senior Vice President and the Treasurer of ARCO. Mrs. Knowles, one of our directors, is an Executive Vice President and the Chief Financial Officer of ARCO. Mr. Voelte, a nominee for director, is an Executive Vice President of ARCO. Transactions Between Vastar and ARCO In October 1993, ARCO transferred to Vastar the producing properties and developed and undeveloped acreage that comprise a substantial portion of our assets. At the time of the transfer, Vastar was a wholly owned subsidiary of ARCO. In conjunction with this property transfer, we issued additional shares of common stock to ARCO. As a result, ARCO now owns 80,000,001 shares, which represented all of the outstanding common stock prior to our initial public offering in 1994. As of the record date on which we determined who is entitled to vote at the 1999 annual stockholders' meeting, ARCO owned approximately 82.1 percent of our common stock. Vastar and ARCO have entered into a number of agreements. Some of these agreements were developed in connection with ARCO's establishment of Vastar. Therefore, they were not the result of arm's-length negotiations between independent parties. After Vastar's initial public offering, Vastar and ARCO have entered into additional or modified agreements, arrangements and transactions. The parties may enter into additional or modified agreements, arrangements and transactions in the future. At least once a year, the audit committee reviews the terms of all material agreements between Vastar and ARCO to assure that these agreements, taken as a whole, are fair to Vastar and its stockholders. The following is a summary of the material arrangements and transactions effective during or occurring in 1998 between Vastar and ARCO or their respective subsidiaries. The descriptions of agreements are only summaries. They do not contain everything contained in the agreements. Some of the items not summarized may be important to you. If you are interested in all of the terms and conditions of these agreements, you should read the entire agreement. We have filed most of these agreements with, and copies can be obtained from, the SEC. Acquisition of Gulf of Mexico Properties In October 1998, we acquired interests in 23 producing fields on the Gulf of Mexico shelf through a three-company transaction involving Vastar, ARCO and Mobil Exploration & Producing U.S. Inc. The net purchase price, comprised of cash and the assumption of debt, was approximately $437.0 million (after certain post-closing adjustments). In this three-way transaction, we purchased all of the stock of Vastar Offshore, Inc. from ARCO. Simultaneously with this purchase, Vastar Offshore traded properties that it had owned in California for the above-described Gulf of Mexico properties. Vastar Offshore was formerly called Western Midway Company when it was a subsidiary of ARCO. We paid approximately $137 million in cash to ARCO at closing. In addition, Vastar Offshore had $300 million indebtedness to ARCO that was repaid on March 23, 1999. 21 The properties acquired include interests in 93 platforms with 295 active wells and interests in over 80 lease blocks in the central and western Gulf of Mexico. We also acquired interests in pipelines, gathering lines and a shorebase in Cameron, Louisiana. Technology Assignments and Licenses In connection with the formation of Vastar, ARCO transferred technology and related intellectual property requested by Vastar through four technology transfer agreements and one intellectual property license agreement. These agreements cover technology and intellectual property owned or otherwise controlled by ARCO in the oil and gas exploration, drilling and production areas in general, and in particular, commercially used technology in the geophysical, geological, geotechnical and oceanographic areas, data processing, data management and computer-based analytical techniques. The agreements allow us to use the technology and intellectual property. The exact method of transfer of this property depended on whether ARCO owned the property outright or had rights to the property under a license and whether the property was or would be used by other ARCO divisions or subsidiaries. For the most part, ARCO provided Vastar with ownership outright, an undivided ownership interest or a paid-up, nonexclusive license. In all cases where ARCO owned the property, ARCO retained for itself the rights to use the property. The licenses granted by ARCO to Vastar do not expire or terminate unless we are in material default under the license. Services Agreements Vastar and ARCO have entered into a number of agreements under which Vastar and ARCO provide services to each other. The principal agreements are: (i) The ARCO Exploration and Production Technology Technical Services Agreement, effective as of October 1, 1993; and (ii) The Corporate Services Agreement, effective as of January 1, 1994. The term of the Technical Services Agreement is indefinite. Either party can terminate it on 30 days' written notice. Generally, either party may terminate any type of service under the Corporate Services Agreement at any time upon 60 days' prior written notice or terminate the entire agreement on 90 days' written notice. However, with respect to the employee information system provided by ARCO, which is used in the administration of our employee payroll and other benefits, ARCO must give us 180 days' notice prior to terminating the service. ARCO provides oil and gas technical services under the Technical Services Agreement and the following services under the Corporate Services Agreement: . Telecommunications; . Computer services; . Internal audit services; . Financial reporting services; . Employee payroll processing; . Employee benefits administration; . Tax and legal services; . Public affairs services; and . Other services, as agreed upon. The services that Vastar can provide ARCO under the Corporate Services Agreement are audit, tax and other services as agreed. 22 In 1998, Vastar paid ARCO $12.2 million for services ARCO performed under these agreements. These services were provided by ARCO at cost. Insurance ARCO provides insurance coverage to us as part of the group of companies insured under ARCO's policies. The insurance provided is customary for the industry but does not fully cover all potential hazards. Coverage and deductibles may be higher than typically maintained by other independent oil and gas companies. The insurance includes public liability, workers' compensation, marine liability, property damage, business interruption, directors' and officers' liability, fiduciary liability and surety bonds. Our annual charge for this insurance is based on an allocation by ARCO of the costs of the various policies. The annual charge was $3.1 million in 1998. Our allocation is reassessed annually based on ARCO's cost for the various lines of insurance and our loss experience and exposure basis. In certain cases, we have elected, and in the future may elect, to supplement or to obtain insurance coverage as opposed to coverage under ARCO's policies. If this happens, Vastar may, but is not required to, terminate insurance coverage under ARCO's policies after giving proper notice. Natural Gas, Crude Oil and Natural Gas Liquids Purchase and Sale Agreements Vastar Gas and Southern Company Energy Marketing provide fuel management services for the natural gas requirements of cogeneration facilities located in California which are partially owned by ARCO or its subsidiaries. Vastar Gas is one of our wholly owned subsidiaries and Southern Company Energy Marketing is a strategic alliance between The Southern Company and us. In addition, ARCO has provided performance guarantees for certain contracts under which Southern Company Energy Marketing is required to sell gas to unrelated cogeneration facilities. These guarantees will continue in effect until the underlying contracts expire. There are no ARCO guarantees on contracts entered into after May 15, 1994. The cogeneration contracts guaranteed by ARCO were originally entered into by Vastar Gas and certain of these contracts transferred to Southern Company Energy Marketing in connection with the formation of Southern Company Energy Marketing in 1997. Vastar also engages in purchases and sales of natural gas, natural gas liquids and crude oil at market-related prices with certain other ARCO affiliates and divisions. During 1998, our revenues from these transactions with ARCO and its affiliates were $119.8 million, or approximately 7 percent of our sales and other operating revenue. Our purchases from ARCO and its affiliates during 1998 were $32.9 million, or approximately 5 percent of our total purchases. Building Lease Vastar's principal office is in Houston, Texas, where it leases approximately 280,000 square feet of a building owned by ARCO at 15375 Memorial Drive. The primary term of the lease expires December 31, 2003, with options to extend for two additional five-year periods. The rent of $294,508 per month was set based upon the rate paid by the other tenant of the building, who is unrelated to ARCO. Under certain conditions, Vastar's lease rent may be reestablished at then-current market rates for comparable office space in Houston. If we cannot agree on a market rate with ARCO, the lease provides for arbitration. We also have a right of first offer for any space in the building that becomes vacant or for purchase of the building if ARCO decides to sell. We provide on-site property management services for the office building in Houston, for which ARCO has agreed to pay us a management fee of $100,000 per year. In 1998, we paid approximately $3.8 million to ARCO under this agreement. 23 Cross-Indemnification Agreement In connection with ARCO's transfer in October 1993 of oil and gas producing properties and undeveloped acreage and assets and liabilities related to the properties and acreage, Vastar and ARCO executed a Cross-Indemnification Agreement. In the agreement, Vastar agreed to indemnify ARCO against: (i) Any and all liabilities associated with the ownership or operation of the properties, including environmental liabilities, with the exception of specific litigation stated in the agreement and other exceptions stated in the agreement; (ii) All liabilities or obligations relating to any ARCO employee benefits plans for any ARCO employee who leaves ARCO and enters the employ of Vastar, except for ARCO retirement benefits accrued under ARCO's plan by employees who transferred to Vastar after our initial public offering which was completed in July 1994; (iii) Liabilities arising under any guarantees by ARCO which ARCO executed to guarantee the performance or payment by Vastar Gas of any natural gas marketing contract between Vastar Gas and any third party; (iv) Any and all liabilities at any time recorded as of October 1, 1993 on financial statements; and (v) The costs of borrowing, carrying and repaying any of our debt. In addition, we agreed to be liable for any sales and use taxes, conveyance, transfer and recording fees and real estate transfer stamps or taxes imposed on any transfer of the properties. We agreed that all other taxes, except income taxes, imposed in respect of oil, natural gas or other hydrocarbons or minerals were to be apportioned between ARCO and us with ARCO paying all the taxes attributable to ownership of the properties prior to October 1, 1993 and Vastar being responsible for paying all other taxes. We agreed that all other out-of-pocket expenses, taxes or fees associated with the consummation of the transfer of the properties to us would be paid by the party incurring the costs. In the Cross-Indemnification Agreement, ARCO agreed to indemnify us against: (i) Any and all liabilities: (a) Retained by ARCO in the agreement or in the agreements transferring the properties; or (b) As to which ARCO indemnified us under the tax sharing agreement described below; and (ii) Liabilities under ARCO benefit plans other than those assumed by us. Tax Sharing Agreement Vastar and its subsidiaries join with ARCO and its domestic subsidiaries in filing consolidated federal income tax returns. As a result, we are jointly and severally liable for the consolidated federal income tax liability of ARCO and its domestic subsidiaries. Vastar and its subsidiaries may also be included in certain state and local income or franchise tax returns of ARCO or its domestic subsidiaries. Vastar and its subsidiaries are parties to a tax sharing agreement with ARCO, effective as of October 1, 1993, that has been amended on several occasions. Under this agreement, ARCO agreed to indemnify us for: (i) Federal, state and local income and franchise tax liabilities that relate to periods on or before October 1, 1993; 24 (ii) Federal income tax liabilities in excess of our share of such tax liabilities as computed under the agreement; and (iii) State and local income and franchise tax liabilities that may be incurred by us and/or our subsidiaries. The right to indemnification is valid only if we have made tax sharing payments in accordance with the agreement. As part of the tax sharing agreement, we pay ARCO the amounts of federal income taxes, including alternative minimum taxes, that we would have to pay if we and our subsidiaries were a separate federal consolidated tax group. We agreed to pay these amounts without regard to the amount of the consolidated tax liability of ARCO and its domestic subsidiaries. Pursuant to the Internal Revenue Code, Section 29 tax credits can be used to reduce the ARCO consolidated tax group's regular income liability after foreign tax credits (the "Regular Tax"), but not below the ARCO consolidated tax group's tentative minimum tax liability. To the extent that Section 29 tax credits are not used by the ARCO consolidated tax group due to this limitation, they are carried forward to be used in a subsequent year to the extent they do not exceed the Regular Tax. Under the tax sharing agreement, we are able to use Section 29 tax credits to reduce our federal income tax payments to ARCO by the greater of (i) the amount of these credits which could be used by Vastar if its tax liability was calculated on a stand-alone tax basis and (ii) the amount of these credits used by the ARCO consolidated tax group, in each case, less a 3.25 percent discount on certain credits. Section 29 tax credits that are not used by us in the current year under the tax sharing agreement can generally be carried forward and used in subsequent tax years. Payments under the agreement are generally made on each date on which a quarterly payment of estimated tax for ARCO and its domestic subsidiaries must be paid, with any final settlement made after the consolidated, combined or unitary return is filed. We are required to pay additional taxes to ARCO if the federal, state or local income tax liability attributable to us and our subsidiaries increases after an audit or for any other reason. If a refund received by ARCO is attributable to us, we are entitled to the refund. When we are entitled to a refund from ARCO, the refund amount is calculated quarterly and is due within 60 days of the due date for the estimated federal income tax payment for that quarter. The agreement appoints ARCO as our sole and exclusive agent in all matters relating to our federal income tax liability. ARCO also has sole and exclusive responsibility to prepare and file with the tax authorities the federal and state income tax returns (including any amendments to these returns) that are subject to the tax sharing agreement. These powers include the exclusive right to contest or compromise any asserted tax adjustment or deficiency and to file, litigate or compromise any claim for refund on our behalf. Corporate Opportunities To address potential conflicts of interest, provisions of our Second Restated Certificate of Incorporation regulate the conduct of our affairs as they may involve ARCO. This certificate of incorporation recognizes and provides that ARCO and Vastar may: (i) Engage in the same or similar activities or lines of business; (ii) Do business with the same customers and suppliers; and (iii) Employ or otherwise engage any person as a director, officer, employee or agent. Our certificate of incorporation further recognizes that ARCO and Vastar may have an interest in the same business opportunities and provides that we may agree upon a method for allocating such business opportunities among each other. To address such potential conflicts, we entered into the 25 Share Purchase Option and Business Opportunities Agreement with ARCO. This agreement is dated as of May 19, 1994. Under this agreement, when an opportunity is offered in writing to someone who is an officer and/or director of both Vastar and ARCO, solely in his or her designated capacity with one of the two companies, the opportunity shall belong to whichever company the opportunity was addressed. If neither Vastar nor ARCO was designated, a business opportunity first offered: (i) To any person who is an officer or an officer and director of Vastar and who is also a director of ARCO, shall belong to Vastar; (ii) To any person who is a director of Vastar and who is also an officer and/or director of ARCO, shall belong to ARCO; (iii) To any person who is an officer, but not a director, of both Vastar and ARCO, shall belong to ARCO; (iv) To any person who is an officer and director of both Vastar and ARCO, shall belong to ARCO; and (v) To any person who is an officer or an officer and director of Vastar and who is also an officer or an officer and director of ARCO, shall belong to ARCO. In the case of any business opportunity not specifically allocated above, whether because of the means by which it arose or was published, or otherwise, either Vastar or ARCO may pursue the business opportunity. The party to which a business opportunity is allocated under the agreement has the right to allow any of its subsidiaries, or affiliates or other entities under its control to pursue the opportunity. If one party to the agreement advises the other that it has no interest in pursuing an opportunity, the other party may pursue the opportunity. Agreement Relating to Preferential Right to Purchase Vastar Common Stock In the Share Purchase Option and Business Opportunities Agreement described above we have agreed to grant ARCO certain rights to purchase our common stock. Under our agreement, ARCO has a right to purchase from time to time the number of shares of common stock or preferred stock, or both, as may be necessary to allow it to continue to include us as part of its consolidated federal tax group. The purchase price for this stock would be the market price at the time of the purchase. PROPOSAL TO APPROVE THE APPOINTMENT OF INDEPENDENT AUDITORS Proposal 2 on Proxy Card The board of directors has appointed PricewaterhouseCoopers LLP (formerly known as Coopers & Lybrand L.L.P.), independent accountants, to audit our consolidated financial statements for the year ending December 31, 1999. This firm has acted as the independent auditors for ARCO, Vastar's principal stockholder, for many years and for ARCO's subsidiaries and affiliates. In addition, from time to time, the firm performs consulting work for Vastar and for ARCO. Except for the existing professional relationships as independent accountant, PricewaterhouseCoopers has no other relationships with ARCO or us. Representatives of PricewaterhouseCoopers LLP will be present at the annual stockholders' meeting and will have the opportunity to make a statement. These representatives will also be available to respond to appropriate questions. The board of directors recommends that you vote FOR the approval of the appointment of PricewaterhouseCoopers LLP. If you sign and return the enclosed proxy card, it will be voted for the election of the nominees listed below unless you specify otherwise on the card. 26 VOTING PROCEDURES The directors described in this proxy statement will be elected at the 1999 annual stockholders' meeting only if: (i) The holders of more than one-half of our common stock who are entitled to vote at the annual stockholders' meeting are present in person or by proxy at the meeting, and (ii) More than one-half of the shares of common stock represented at that meeting are voted for the directors. The board of directors has appointed election inspectors for the meeting who will tabulate the votes. In tabulating the votes, abstentions and broker non- votes will be counted as present by the election inspectors for the purpose of determining the presence of a quorum. For the purpose of computing the vote required for the election of directors, the election inspectors will treat shares held by a stockholder who abstains from voting as being present and entitled to vote on the matter. Thus, an abstention has the same legal effect as a vote against the matter. However, in the case of a broker non-vote, or if a stockholder withholds authority from his proxy to vote the proxy on a particular matter, the shares represented by the proxy will not be treated as present or entitled to vote on the matter. Thus, a broker non-vote or the withholding of a proxy's authority will have no effect on the outcome of the vote on the election of directors. A "broker non-vote" refers to shares of common stock represented at the meeting by a bank, broker or a nominee, where the bank, broker or nominee (i) has not received voting instructions on a matter from persons entitled to vote and (ii) does not have the discretionary voting power on the matter. OTHER BUSINESS The board of directors is not aware of any other matters to be presented at the 1999 annual stockholders' meeting. If any other matters should properly come before the meeting, the persons named as proxies in the enclosed proxy card will vote the proxies in accordance with their best judgment. VOTING OF STOCK IN PLAN ACCOUNTS Our Capital Accumulation and Savings Plans permit plan participants to direct the plan trustees on how to vote the common stock allocated to their accounts. If the trustee does not receive participant directions for shares held by it, those shares will be voted in the same proportion as those shares of common stock for which directions are received. PROXY SOLICITATION We will pay all expenses of soliciting the proxies described in this proxy statement. Solicitations will be made primarily by mail but some of our officers and other employees may solicit proxies personally, by telephone and by mail, if deemed appropriate. Brokers and nominees will be requested to obtain voting instructions from beneficial owners of stock registered in their names. 27 STOCKHOLDER PROPOSALS FOR 2000 ANNUAL MEETING Rule 14a-8 promulgated under the Securities and Exchange Act of 1934, as amended, requires that we include certain stockholder proposals in our proxy statement for the annual stockholders' meeting to be held in 2000 if the proposal is submitted prior to the deadline calculated under the rule. If stockholders desire their proposal to be considered for inclusion in our proxy statement relating to the annual stockholders' meeting to be held in 2000, we must receive the proposal no later than November 24, 1999. If a stockholder desires a matter to be considered at the annual stockholders' meeting to be held in 2000 and his or her proposal was not submitted for inclusion in our proxy statement by the November 24, 1999 deadline described above, the matter may still be considered at the meeting if the notice procedures outlined in our bylaws are followed. Information regarding the matter would not, however, be contained in our proxy statement relating to the meeting. Our bylaws provide that only stockholders of record entitled to vote at an annual meeting of stockholders may nominate a person for election to the board of directors or propose other business to be considered by the stockholders at an annual meeting. These stockholders must send us a written notice of the nomination or proposal. We must receive the notice not earlier than the ninetieth day nor later than the sixtieth day prior to the first anniversary of the preceding year's annual meeting. For the annual stockholders' meeting to be held in 2000, this means that we must receive the notice no earlier than February 17, 2000 and no later than March 19, 2000. Special rules described in the bylaws may apply (i) in the event that the date of the annual meeting is more than thirty days before or more than sixty days after the first anniversary of the preceding year's annual meeting, (ii) for nominations for certain board vacancies created by an increase in the size of the board and (iii) special stockholders' meetings. We have filed our bylaws with, and a copy of these bylaws can be obtained from, the SEC. Please address all notices to the Secretary of Vastar Resources, Inc., 15375 Memorial Drive, Houston, Texas 77079. SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE Section 16(a) of the Securities Exchange Act of 1934 requires certain of our officers and directors, and persons who own more than 10 percent of a registered class of Vastar's equity securities, to file reports of ownership and changes in ownership with the SEC and with the New York Stock Exchange. These reports are made on SEC Forms 3, 4 and 5. Such officers, directors and greater than 10 percent stockholders are required by SEC regulations to furnish us with copies of all Section 16(a) forms they file. On the basis of reports and representations submitted by Vastar's directors and executive officers, all Forms 3, 4 and 5 showing ownership of and changes of ownership in Vastar's equity securities during 1998 were timely filed with the SEC as required by Section 16(a) of the Exchange Act, except that, due to an inadvertent oversight, Terry G. Dallas, a director of the Company, did not timely file a report related to an aggregate of 2.518 shares acquired with dividend reinvestments. A report on these shares has been filed. 28 ADDITIONAL INFORMATION AVAILABLE We file an Annual Report on Form 10-K with the SEC. You may obtain a copy of this report and any amendments to the report, without exhibits, at no charge, by writing to our Investor Relations Department at the following address: Vastar Resources, Inc., 15375 Memorial Drive, Houston, Texas 77079, Telephone: (281) 584-3477.
