The ISOs are listed first in the foregoing table and the NQSOs are listed second. The ISOs and NQSOs were granted subject to a three-year vesting period, with approximately one-third of the options granted becoming exercisable each year commencing on the first anniversary of the grant date and ending on the third anniversary. The vesting and exercisability of the options will be accelerated in the event of a Change of Control (as defined in the 2001 Incentive Compensation Plan). No stock appreciation rights were granted in 2001. (2) Options are granted at market price on the day of the grant. The exercise price and tax withholding obligations related to exercise may be paid by delivery of already owned shares or by offset of the underlying shares, subject to certain conditions. (3) The options were granted for terms of 10 years. Upon the termination of an optionee's employment, the options continue to vest and remain exercisable (depending on the cause of termination) for a period of up to the remaining term of each option. However, under the provisions of his employment agreement, the options granted to Dr. Irani become fully vested immediately in the event of termination by Occidental or his retirement and are then exercisable for the remaining term of the option. Under the terms of his employment agreement, the options granted to Dr. Laurance become fully vested immediately in the event of termination by Occidental and are exercisable for the remaining term of the option. Under the terms of their respective employment agreements, the options granted to Messrs. Hirl, Chazen and de Brier continue to vest and are exercisable for the remaining term of the agreement. See "Employment Agreements" below. (4) The dollar amounts in these columns are the result of calculations at the 5% and 10% annual appreciation rates for the term of the options (10 years) as required by the Securities and Exchange Commission, and therefore are not intended to predict future appreciation, if any, in the price of Occidental common stock. 11

The number of shares received at the end of the performance period will depend on the attainment of performance objectives based on a peer company comparison of total stockholder return. Depending on Occidental's ranking among its peers and subject to the grantee remaining employed throughout the performance period, the grantee receives shares of common stock in an amount ranging from 0% to 200% of the Target Share Award; provided, however, if the grantee dies, becomes disabled, retires or is terminated for the convenience of the company during the performance period, then the grantee will forfeit the right to receive a pro rata portion of the pay out based on the days remaining in the performance period after such event. During the performance period, dividend equivalents are credited on the Target Shares in an amount equal to the per share dividend declared per share of common stock and cash equal to the dividend equivalent is paid to the grantees. In the event of a Change of Control (as defined in the 1995 Incentive Stock Plan), the grantee's right to receive the number of Target Shares becomes nonforfeitable. (2) Under the terms of his employment agreement, any long-term incentive awards granted to Dr. Irani become fully vested immediately in the event of termination by Occidental or his retirement. See "Employment Agreements" below. (3) Under the terms of his employment agreement, any long-term incentive awards granted to Dr. Laurance become fully vested immediately in the event of termination by Occidental. See "Employment Agreements" below. (4) Under the terms of their respective employment agreements, the performance period for the entire award granted to Messrs. Hirl, Chazen and de Brier continues in the event of termination without cause for the remaining term of the agreement. See "Employment Agreements" below. 12

- -------------------------------------------------------------------------------- EMPLOYMENT AGREEMENTS The following are summaries of the employment agreements between Occidental and the executive officers named in the Compensation Tables. Copies of the agreements are available as exhibits to Occidental's periodic reports filed with the Securities and Exchange Commission. DR. IRANI On November 17, 2000, Dr. Irani entered into an amended and restated employment agreement with Occidental. The agreement, as amended, is for a term expiring on the earlier of Occidental's 2007 Annual Meeting of Stockholders or May 30, 2007 with an annual salary at a minimum rate of $1,250,000, subject to annual increase (and, as part of across-the-board reductions for other officers, decrease) at the reasonable discretion of the Board of Directors and the Executive Compensation and Human Resources Committee. In addition, Dr. Irani is eligible for a discretionary annual cash bonus and to participate in Occidental's qualified and nonqualified retirement plans, its incentive stock plan, deferred compensation plan and any future performance plans adopted by Occidental as well as any group life insurance, medical care (including coverage for his wife and children), disability and other plans or benefits which Occidental may provide for him. Prior to his retirement, Dr. Irani will receive life insurance at least equal to three times his highest career annual salary, which life insurance shall be assignable at Dr. Irani's option. During the term of his employment, Dr. Irani will receive six weeks paid vacation each calendar year (which will accrue and for which he will be entitled to be paid for any accrued but unused vacation time upon termination of the agreement) and the minimum perquisites to which he was entitled prior to the effective date of his agreement. See also footnote (3) to the Compensation Table on page 9. Following his retirement or upon the termination of his employment by Occidental, Dr. Irani will continue to receive life insurance equal to twice his highest career annual salary, medical benefits and the personal tax, accounting and financial planning services currently provided to him. Upon retirement, notwithstanding the provisions of the award agreements, all of Dr. Irani's unvested stock options and restricted stock awards will immediately vest and his performance stock awards will become immediately vested and fully payable. If the agreement is terminated due to Dr. Irani's death, Dr. Irani's estate will be entitled to a pro-rata portion of any bonus he was eligible to receive for the year of his death. If Dr. Irani is married at the time of his death, his wife will be entitled, for the remainder of her life, to continuation of medical benefits throughout her life. If Dr. Irani is terminated by Occidental for any reason, or if Dr. Irani terminates employment because Occidental materially breaches the agreement, Dr. Irani is entitled to receive three times his highest annual salary and bonus for any calendar year commencing with January 1, 2000 (subject to certain offsets of disability benefits in the case of termination due to disability), without obligation to mitigate, payable, at Dr. Irani's option, in equal monthly installments over three years or in an undiscounted lump sum. In such event of termination, Dr. Irani is also entitled to receive his medical, welfare and life insurance benefits; and if such termination is not due to death or disability, his existing perquisites and the full and immediate vesting of his restricted stock, stock options and any other long-term incentive benefits; provided that the options or stock appreciation rights shall be exercisable as if he had retired on such date and that nothing in his employment agreement affects his existing grant agreements. If after termination of his employment Dr. Irani is not eligible to participate in Occidental's benefit plans as contemplated by his employment agreement, then Occidental will provide Dr. Irani with substantially equivalent benefits and will reimburse him for any additional tax liabilities incurred by him as a result of his receipt of such benefits. If Occidental materially breaches the agreement and does not cure the breach after notice thereof, Dr. Irani may terminate his employment and treat such occurrence as if it were a termination by Occidental; provided that it shall not be a material breach if, following the merger or sale of Occidental or substantially all of its assets, Dr. Irani continues to have substantially the same executive duties and reports to the acquirer's board of directors. The agreement also holds Dr. Irani harmless from the effects of any excise or other taxes payable under or as a result of Sections 280G and 4999 of the Internal Revenue Code of 1986 or comparable state law by reason of a change of control, including taxes payable on any amounts paid pursuant to this hold harmless provision. During and after the term of the agreement, Dr. Irani is entitled to the payment of all legal fees other than those of a purely personal nature. In addition, the agreement provides for additional indemnification for Dr. Irani to the fullest extent permitted by applicable law and for Occidental to maintain Directors' and Officers' liability insurance 13

[OXY LOGO]---------------------------------------------------------------------- with policy limits aggregating not less than $100 million, insuring Dr. Irani against occurrences which occur during the term of the agreement. DR. LAURANCE On November 17, 2000, Dr. Laurance entered into an amended and restated employment agreement with Occidental. The agreement, as amended, is for a five-year term with an annual salary at a minimum rate of $990,000, subject to annual increase (and, as part of across-the-board reductions for other officers, decrease) at the reasonable discretion of the Board of Directors and the Executive Compensation and Human Resources Committee. In addition, Dr. Laurance is eligible for a discretionary annual cash bonus and to participate in Occidental's qualified and nonqualified retirement plans, its incentive stock plan, deferred compensation plan and any future performance plans adopted by Occidental as well as any group life insurance, medical care (including coverage for his wife and children), disability and other plans or benefits which Occidental may provide for him. Prior to his retirement, Dr. Laurance will receive life insurance at least equal to three times his highest career annual salary, which insurance shall be assignable at Dr. Laurance's option. During the term of his employment, Dr. Laurance will receive the minimum perquisites to which he was entitled prior to the effective date of his agreement. See also footnote (5) to the Compensation Table on page 10. Following his retirement or upon the termination of his employment by Occidental, Dr. Laurance will continue to receive life insurance equal to twice his highest career annual salary, medical benefits no less favorable than those provided to Dr. Laurance prior to such retirement or termination, and the personal tax, accounting and financial planning services he currently receives. If the agreement terminates due to Dr. Laurance's death, Dr. Laurance's estate will be entitled to a pro-rata portion of any bonus he was entitled to have received for the year of his death. If Dr. Laurance is married at the time of his death, his wife will be entitled, for the remainder of her life, to continuation of medical benefits throughout her life. If Dr. Laurance is terminated by Occidental for any reason, or if Dr. Laurance terminates employment because Occidental materially breaches the agreement, Dr. Laurance is entitled to receive three times his highest annual salary and bonus for any calendar year commencing with January 1, 2000 (subject to certain offsets of disability benefits in the case of termination due to disability) without obligation to mitigate, payable, at Dr. Laurance's option, in equal monthly installments over three years or in an undiscounted lump sum. In such event of termination, Dr. Laurance is also entitled to receive his medical, welfare and life insurance benefits; and if such termination is not due to death or disability, the full and immediate vesting of his restricted stock, stock options and any other long-term incentive benefits; provided that the options or stock appreciation rights shall be exercisable as if he had retired on such date and that nothing in his employment agreement affects his existing grant agreements. If after termination of his employment Dr. Laurance is not eligible to participate in Occidental's benefit plans as contemplated by his employment agreement, then Occidental will provide Dr. Laurance with substantially equivalent benefits and will reimburse him for any additional tax liabilities incurred by him as a result of his receipt of such benefits. If Occidental materially breaches the agreement and does not cure the breach after notice thereof, Dr. Laurance may terminate his employment and treat such occurrence as if it were a termination by Occidental; provided that it shall not be a material breach if, following the merger or sale of Occidental or substantially all of its assets, Dr. Laurance continues to have substantially the same executive duties and reporting relationships. The agreement also holds Dr. Laurance harmless from the effects of any excise or other taxes payable under or as a result of Sections 280G and 4999 of the Internal Revenue Code of 1986 or comparable state law by reason of a change of control, including taxes payable on any amounts paid pursuant to this hold harmless provision. During and after the term of the agreement, Dr. Laurance is entitled to the payment of all legal fees other than those of a purely personal nature. In addition, the agreement provides for additional indemnification for Dr. Laurance to the fullest extent permitted by applicable law and for Occidental to maintain Directors' and Officers' liability insurance with policy limits aggregating not less than $100 million, insuring Dr. Laurance against occurrences which occur during the term of the agreement. 14

- -------------------------------------------------------------------------------- MR. HIRL On December 13, 2001, Mr. Hirl entered into a new employment agreement with Occidental to reflect Mr. Hirl's desire to begin phased retirement. Under his agreement, Mr. Hirl continued to serve as the President and Chief Executive Officer of Occidental Chemical Corporation through December 31, 2001. From January 1, 2002 until his retirement on June 30, 2003, he will continue to serve as an Executive Vice President of Occidental. During the term of the agreement, Mr. Hirl will receive an annual salary of not less than $660,000. If Mr. Hirl's employment is terminated as a result of incapacity and he is a participant in and qualifies for benefits under Occidental's Long-Term Disability Plan, Occidental will pay Mr. Hirl the difference between 60 percent of his annual salary and the maximum annual disability benefit, for so long as he remains eligible to receive disability benefits. In the event he is terminated without cause, Mr. Hirl will receive his then current base salary rate for the remaining term of his agreement and will continue to be eligible to participate in all employee benefit plans available to salaried employees and senior executives and to exercise options previously granted him that are or become exercisable. Following his retirement and if he executes the consulting agreement annexed to his agreement, Mr. Hirl will continue as a consultant to Occidental until June 30, 2005, at an annual salary of $200,000. MR. CHAZEN Mr. Chazen has an employment agreement with Occidental for a term expiring in October 2005, providing for an annual salary of not less than $572,000. If Mr. Chazen's employment is terminated as a result of incapacity and he is a participant in and qualifies for benefits under Occidental's Long-Term Disability Plan, Occidental will pay Mr. Chazen the difference between 60 percent of his annual salary and the maximum annual disability benefit, for so long as he remains eligible to receive disability benefits.

DE BRIER Mr. de Brier has an employment agreement with Occidental for a term expiring in May 2003, providing for an annual salary of not less than $530,000. If Mr. de Brier's employment is terminated as a result of incapacity and he is a participant in and qualifies for benefits under Occidental's Long-Term Disability Plan, Occidental will pay Mr. de Brier the difference between 60 percent of his annual salary and the maximum annual disability benefit, for so long as he remains eligible to receive disability benefits. In the event he is terminated without cause, Mr. de Brier will receive an amount equal to twice the sum of his highest base salary and annual cash bonus target, which amount is payable in equal monthly installments over a two year compensation period. During the compensation period, Mr. de Brier will continue to be eligible to participate in all employee benefit plans available to salaried employees and senior executives and to exercise options previously granted him that are or become exercisable. During the compensation period, any stock awards granted prior to Mr. de Brier's termination will continue to vest in the same manner and in the same amounts as if he continued as a full-time employee. REPORT OF THE EXECUTIVE COMPENSATION AND HUMAN RESOURCES COMMITTEE The Executive Compensation and Human Resources Committee of the Board of Directors is responsible for Occidental's executive compensation programs. The Committee is selected from members of the Board of Directors who are Independent Directors as defined under Occidental's Corporate Governance Policies. This report is provided by the Committee to assist stockholders in understanding the philosophy and objectives underlying the compensation of Occidental's senior executives. 15

[OXY LOGO]---------------------------------------------------------------------- PHILOSOPHY Occidental's executive compensation programs are designed to attract and retain top quality executive talent and also to provide incentives for them to enhance stockholder value. The Committee is guided by the following principles that are included in Occidental's Corporate Governance Policies: o Compensation arrangements shall focus on pay for performance to encourage the retention of employees who make significant contributions to Occidental's performance; o Compensation arrangements shall encourage executive stock ownership to align the interests of management and stockholders; o Compensation arrangements shall maintain an appropriate balance between base salary and annual and long-term incentive opportunities; o Decisions concerning the compensation of individual executives shall take into consideration compensation history, including any special compensation payments. o The Committee shall link pay to the achievement of financial goals set in advance for any senior management cash incentive compensation plans; o The Committee shall set annual and long-term performance goals for the Chairman of the Board and Chief Executive Officer and evaluate his performance against such goals and the performance of Occidental's peer companies; and o The Committee shall hold an executive session at least once a year at which employee directors are not present. Occidental is committed to the principle of pay-for-performance. The compensation programs described below link executive compensation to business performance that in turn enhances stockholder value. EXECUTIVE COMPENSATION PROGRAMS Occidental's executive compensation programs are composed of three main elements: o Base salary o Annual cash incentives o Long-term incentives Base salary and annual cash incentives are designed to attract and retain top quality executives and to recognize individual performance and the achievement of business objectives each year. The value of long-term incentives is directly linked to the performance of the common stock and, therefore, to total stockholder return. Long-term incentives have been granted in the form of stock options, performance stock and restricted stock. In evaluating Occidental's executive compensation programs, the Committee solicits the services of outside compensation consultants and Occidental's compensation staff regarding plan design and industry pay practices. Occidental participates in several compensation surveys each year that are conducted by third-party compensation consulting firms. A number of these surveys are focused primarily on major U.S. oil and chemical companies (including companies within the peer groups selected for the graph presented under the subheading "Performance Graph"). CASH COMPENSATION In determining base salary levels, Occidental maintains an administrative framework of job levels into which positions are assigned based on internal comparability and external market data. Base salaries and the other components of compensation are reviewed annually and adjusted as appropriate to reward performance and maintain our competitive position. From time to time, other forms of compensation may be utilized in lieu of an annual adjustment. 16

- -------------------------------------------------------------------------------- Since 1995, cash incentive awards have been granted under the Occidental Petroleum Corporation Executive Incentive Compensation Plan. Participation is determined by job level and is intended to reward individuals who have a significant impact on business performance. Under the Executive Incentive Compensation Plan, 60 percent of a participant's award is based on the attainment of predetermined financial objectives by Occidental and its subsidiaries and 40 percent is based on a subjective assessment of the participant's achievement of predetermined individual performance objectives and the participant's response to unanticipated challenges during the plan year. LONG-TERM INCENTIVES The Committee grants long-term incentive awards, generally in the form of stock options, restricted stock or performance stock grants, based on its assessment of an executive's contributions and potential to influence Occidental's future performance. The Committee believes that long-term awards should create a long-term incentive to increase stockholder value and provide a retention vehicle for key executives. The Committee also believes that such stock-based compensation encourages executives to view Occidental from the stockholders' perspective. EMPLOYMENT AGREEMENTS Occidental offers employment agreements to key executives only when it is in the best interest of Occidental and its stockholders to attract and retain such key executives and to ensure continuity and stability of management. In accordance with a policy adopted by the Board of Directors in September 1992, no employment agreements with new executives will contain provisions, commonly referred to as "golden parachutes," that provide for additional severance benefits in the event of a change in control. For a summary of the employment agreements for the named executive officers, see "Employment Agreements" beginning at page 13. DEDUCTIBILITY OF COMPENSATION Section 162(m) of the Internal Revenue Code limits the deduction of compensation paid to the chief executive officer and other named executive officers to the extent the compensation of a particular executive exceeds $1 million, unless such compensation is based upon stock price appreciation over market value at the date of grant (in the case of stock options) or predetermined quantifiable performance goals (in the case of other incentive compensation) or paid pursuant to a written contract that was in effect on February 17, 1993. Although the Committee considers the tax consequences of its compensation decisions, it is not the policy of the Committee to pay only deductible compensation, rather the Committee gives priority to other objectives in circumstances it deems appropriate. 2001 COMPENSATION DECISIONS In December 2000, the Executive Compensation and Human Resources Committee approved, effective January 1, 2001, industry-competitive salary increases for the named executive officers to acknowledge personal accomplishments and excellent performance during 2000. Dr. Irani received a 4% salary increase. The Committee also increased bonus targets for performance during 2001 for two of the named executive officers to reflect competitive practice for senior executive officers in peer companies in the oil and chemical industries. Dr. Irani's bonus target was increased from 85% to 100% of his base salary. Also in December 2000, the Committee granted, effective January 1, 2001, performance stock awards under the 1995 Incentive Stock Plan. In granting awards to the named executives, the Committee considered overall contributions, competitive practices among peer companies in the oil industry, and each executive's potential to affect Occidental's future performance. The performance stock award for Dr. Irani, in the amount of 75,052 shares, is consistent with awards to similarly compensated executive officers of peer companies in the oil industry. In addition, in December 2000, the Committee established primary performance goals for Dr. Irani for 2001. The goals included key financial objectives, the enhancement of the long-term value of Occidental's portfolio of assets, the improvement of earnings through on-going business growth, decreased operating and overhead 17

[OXY LOGO]---------------------------------------------------------------------- costs, debt reduction, and cash generation from certain business segments, and the maintenance of a high performing organization through continued emphasis on corporate-wide leadership training and enhanced communications. In April 2001, the Committee reviewed and approved a restatement of Occidental's Executive Incentive Compensation Plan, the annual bonus plan for executives. The restatement covers eligibility for participation; the establishment of target awards, payout ranges, and performance measures; the payment of awards; and required approvals. The Committee also approved amendments to Occidental's Deferred Compensation Plan and Supplemental Retirement Plan. In addition, the Committee approved an amendment to the 2001 Incentive Compensation Plan to clarify and confirm that any stock options granted by Occidental will not be repriced, replaced, or regranted through cancellation, or by lowering the option exercise price of a previously granted award, without shareholder approval. In July 2001, the Committee reviewed and approved annual stock option grants under the 2001 Incentive Compensation Plan. Grants were based on competitive practices in the oil and chemical industries, as well as a subjective assessment of each executive's individual performance and potential to contribute to Occidental's future performance. The Committee approved a grant of non-qualified and qualified stock options to Dr. Irani in the amount of 1,300,000 shares, in recognition of Dr. Irani's leadership role in sustaining Occidental's high performance levels. In November 2001, the Committee reviewed and approved a new employment agreement for Mr. Hirl, whereby Mr. Hirl agreed to serve as Executive Vice President of Occidental Petroleum through June 30, 2003, after which Mr. Hirl will retire from Occidental and serve as a consultant to the Company through June 30, 2005. A summary of the employment contract is set forth on page 15. In December 2001, the Committee and the Lead Independent Director reviewed Dr. Irani's performance goals and objectives for 2001 and noted Dr. Irani's significant accomplishments during 2001 in improving corporate earnings and reducing debt and overhead costs. The Committee also considered salary increases for the named executive officers for 2002 and decided that restricted stock awards should be granted, effective December 12, 2001, in lieu of salary increases. The approved awards reflected individual contributions, Occidental's outstanding business results, competitive survey data, and the impact of the forfeited salary increase on annual bonus opportunities, retirement and savings plan contributions, performance stock incentives, and other benefits. Dr. Irani was awarded a restricted stock award of 90,000 shares. In February 2002, the Committee reviewed annual bonus awards for 2001. As described above, awards under the Executive Incentive Compensation Plan to the named executive officers, including Dr. Irani, are based on the achievement of predetermined financial goals (60%), including earnings per share, and the achievement of predetermined individual goals (40%). Because of the achievement in 2001 of the Company's financial goals and his individual goals as noted above, Dr. Irani received a cash bonus award of $2,600,000. In February 2002, the Committee also certified the payouts to be made under the 1995 Incentive Stock Plan for performance stock awards granted in January 1998, for which the performance period ended December 31, 2001. In certifying the awards, the Committee modified the awards to adjust for the fact that certain of the peer group companies listed in the award agreements had merged or ceased to exist by the end of the performance period. The awards to "covered employees" are reflected in the Summary Compensation Table on page 9. Dr. Irani received a payment of 47,488 shares of stock from his 1998 performance stock award.

- -------------------------------------------------------------------------------- PERFORMANCE GRAPH The following graph compares the yearly percentage change in the cumulative total return of the common stock with the cumulative total return of the Standard & Poor's 500 Stock Index and with that of the original peer group and the revised peer group over the five-year period ending on December 31, 2001. The graph assumes that $100 was invested in Occidental common stock, in the stock of the companies in the Standard & Poor's 500 Index and in the stocks of the peer group companies just prior to the commencement of the period (December 31, 1996) and that all dividends received within a quarter were reinvested in that quarter. The original peer group companies are Anadarko Petroleum Corporation, Burlington Resources Inc., Conoco Inc., Georgia Gulf Corporation, Kerr-McGee Corporation, Lyondell Petrochemical Corporation, Occidental, Phillips Petroleum Corporation and Unocal Corporation. The revised peer group companies are Amerada Hess Corporation, Anadarko Petroleum Corporation, Burlington Resources Corporation, Georgia Gulf Corporation, Kerr McGee Corporation, Lyondell Petrochemical Corporation, Occidental, Phillips Petroleum Corporation and Unocal Corporation. Occidental revised the peer group to substitute Amerada Hess Corporation for Conoco, Inc. which is in the process of merging with Phillips Petroleum Corporation.

[OXY LOGO]---------------------------------------------------------------------- AUDIT AND OTHER FEES ------------ AUDIT FEES The aggregate fees incurred for professional services rendered by Arthur Andersen LLP for the audit of Occidental's annual financial statements for the fiscal year ended December 31, 2001 and for the reviews of the financial statements included in Occidental's Quarterly Reports on Form 10-Q for that fiscal year were $3,906,000. AUDIT RELATED FEES Fees of $1,164,000 were incurred for professional services rendered by Arthur Andersen LLP for the fiscal year ended December 31, 2001, for audit related services, including statutory and subsidiary audits, employee benefit plan audits, and accounting research assistance and structure review on proposed transactions such as financings and acquisitions. FINANCIAL INFORMATION SYSTEMS DESIGN AND IMPLEMENTATION FEES No fees were incurred for professional services rendered by Arthur Andersen LLP for information technology services relating to financial information system design and implementation for the fiscal year ended December 31, 2001. ALL OTHER FEES The aggregate fees incurred for services rendered by Arthur Andersen LLP to Occidental, other than the services described above under "Audit Fees", "Audit Related Fees" and "Financial Information System Design and Implementation Fees", for the fiscal year ended December 31, 2001 were $4,885,000, which includes $2,000,000 for internal audit assistance and $1,000,000 for assistance in integrating operations following an acquisition in April 2000 and the balance primarily for tax related services. Occidental will use Ernst & Young LLP instead of Arthur Andersen LLP for internal audit assistance beginning in 2002. REPORT OF THE AUDIT COMMITTEE ------------ The Audit Committee has reviewed and discussed Occidental's audited financial statements for the fiscal year ended December 31, 2001 with management. In addition, the Audit Committee has discussed with Arthur Andersen LLP, Occidental's independent public accountants, the matters required to be discussed by Statement on Auditing Standards No. 61, Communication with Audit Committees, as amended and as currently in effect. The Audit Committee received from Arthur Andersen LLP written disclosures and the letter regarding its independence as required by Independence Standards Board Standard No. 1, Independence Discussions with Audit Committees, as amended and as currently in effect. The Audit Committee has also considered whether the provision of non-audit services provided by Arthur Andersen LLP to Occidental is compatible with maintaining their independence and has discussed with the auditors the auditors' independence. Based upon the reports and discussions described in this report, the Audit Committee recommended to the Board that the audited financial statements be included in Occidental's Annual Report on Form 10-K for the year ended December 31, 2001, to be filed with the Securities and Exchange Commission. Respectfully submitted, THE AUDIT COMMITTEE Rosemary Tomich (chairman) Irvin W. Maloney Aziz D. Syriani 20

- -------------------------------------------------------------------------------- SELECTION OF INDEPENDENT PUBLIC ACCOUNTANTS ------------ The Audit Committee of the Board of Directors of Occidental is reviewing the selection of independent public accountants to audit the consolidated financial statements of Occidental and its subsidiaries for the year ending December 31, 2002, in light of the recent indictment of Arthur Andersen LLP. Arthur Andersen LLP has audited Occidental's financial statements annually since 1961. A member of that firm is expected to be present at the annual meeting, will have an opportunity to make a statement if so desired and will be available to respond to appropriate questions. STOCKHOLDER PROPOSALS ------------ Occidental has been advised by four holders of common stock of their intention to introduce at the annual meeting the following proposals and supporting statements. The Board of Directors disclaims any responsibility for the content of the proposals and for the statements made in support thereof, which are presented as received from the stockholders. PROPOSAL 2: POLICY ON POISON PILLS Mr. Emil Rossi of Boonville, California, the owner of 415 shares of common stock, has notified Occidental that he intends to present the following proposal at the 2002 annual meeting. "Occidental shareholders request that our Board of Directors adopt a meaningful shareholder vote policy on poison pills. This consistent single policy includes a shareholder vote prior to adopting any poison pill and also redemption or termination of any pill now in effect unless it has been approved by a shareholder vote at the next shareholder meeting. The poison pill is an important issue for shareholder vote even if our company does not now have a poison pill or plan to adopt a poison pill in the future. Currently our Board can adopt a poison pill and/or redeem a current poison pill and adopt a new poison pill: 1) At any time 2) In a short period of time 3) Without shareholder approval NEGATIVE EFFECTS OF POISON PILLS ON SHAREHOLDER VALUE A study by the Securities and Exchange Commission found evidence that the negative effect of poison pills to deter profitable takeover bids outweigh benefits. Source: Office of the Chief Economist, Securities and Exchange Commission, The Effect of Poison Pills on the Wealth of Target Shareholders, October 23, 1986. ADDITIONAL SUPPORT FOR THIS PROPOSAL TOPIC: o Pills adversely affect shareholder value. "Even though [the pills] are designed as protection and not intended ever to be triggered, the pills are poison, indeed. The basic function of pills is, simply stated, to confront a hostile purchaser with immediate and unacceptable dilution of the value of his investment. The pill is a `doomsday device,' with such potent wealth destroying characteristics ..." Power and Accountability Robert Monks and Nell Minow Chapter 2, page 49 after "1,000 Poison Pills" heading. Source: www.thecorporatelibrary.com/power 21

[OXY LOGO]---------------------------------------------------------------------- o The Council of Institutional Investors www.ciiorg/ciicentral/policies.htm & www.cii.org recommends shareholder approval of all poison pills. INSTITUTIONAL INVESTOR SUPPORT Many institutional investors believe poison pills should be submitted for a vote by shareholders. Institutional investors include: 1. Teachers Insurance and Annuity Association College Retirement Equities Fund (TIAA-CREF) Source: TIAA-CREF Policy Statement on Corporate Governance 2. California Public Employees Retirement System (CalPERS) Source: CalPERS U.S. Corporate Governance Principles. IV. Governance Guidelines, D. Shareholder Rights. A poison pill is such a powerful tool that shareholders should be able to vote on whether it is appropriate. We believe a shareholder vote on poison pills will avoid an unbalanced concentration of power in our directors who could focus on narrow interests at the expense of the vast majority of shareholders. INSTITUTIONAL INVESTOR SUPPORT IS HIGH-CALIBER SUPPORT Additional evidence of significant institutional support is the sponsorship by institutional investors such as TIAA-CREF, Gamco Investors and the New York State Retirement Fund of their own proposals on this same topic. Shareholder right to vote on poison pill resolutions achieved a 57% average yes-vote from shareholders at 26 major companies in 2000. Source: IRRC /Average Voting Results, 9/27/00. Institutional investor support is high-caliber support. Institutional investors have the advantage of a specialized staff and resources, long-term focus, fiduciary duty and independent perspective to thoroughly study the issues involved in this proposal topic. 68% VOTE AT A MAJOR COMPANY This proposal won 68% of the yes-no vote at the Burlington Northern Santa Fe (BNI) 2001 annual meeting. The text of the BNI proposal and 68%-vote data is available at the Securities and Exchange Commission website under EDGAR Archives: BNI 2001 reports DEF 14 and 10-Q. SHAREHOLDER VOTE PRECEDENT SET BY OTHER COMPANIES In recent years, various companies have given shareholders a meaningful vote on this topic. Our company should do so as well. In the interest of shareholder value vote yes: SHAREHOLDER VOTE ON POISON PILLS YES ON 2 THE BOARD OF DIRECTORS' STATEMENT IN OPPOSITION Occidental does not currently have a poison pill. However, the Board of Directors feels that it is in the best interests of Occidental and its stockholders that the Board of Directors retain the flexibility to adopt an anti-takeover provision if and when necessary. A study by Georgeson Shareholder Communications Inc showed that between 1992 and 1996, stockholders of companies with "poison pills" received significantly higher value than companies without them. (Georgeson Shareholder Communications Inc., "Mergers & Acquisitions: Poison Pills and Shareholder Value/1992-1996," 1997). Rather than harm shareholder value, as has been suggested by the proponent, the ability to adopt an anti-takeover provision would give Occidental a better position from which to bargain with a potential buyer. This better bargaining position should lead to a higher value for stockholders. The Board of Directors has a fiduciary duty to act in the best interests of Occidental and its stockholders. Any decision to adopt an anti-takeover provision, such as a poison pill, would be made only after deliberation by the 22

- -------------------------------------------------------------------------------- Board. The Board is in the best and most informed position to evaluate and consider whether circumstances call for the adoption of an anti-takeover provision in order to protect Occidental and its stockholders. Accordingly, the Board of Directors recommends a vote AGAINST Proposal 2. Proxies solicited by the Board of Directors will be so voted unless stockholders specify otherwise in the proxy card. PROPOSAL 3: REPORT ON GLOBAL WARMING EMISSIONS Walden/BBT Domestic Social Index Fund, 40 Court Street, Boston, Massachusetts 02108, the owner of 1100 shares of common stock, The Sinsinawa Dominicans, 7200 W. Division Street, River Forest, Illinois 60305, the owner of 100 shares of common stock, and The Needmor Fund, 275 South Main Street, Suite 206, Longmont, Colorado 80501 the owner of 1100 shares of common stock, have each notified Occidental that they intend to present the following proposal at the 2002 annual meeting. "WHEREAS: o The Intergovernmental Panel on Climate Change has found "new and stronger evidence that most of the warming observed over the last 50 years is attributed to human activity." (See www.ipcc.ch/Climate Change 2001: The Scientific Basis/Summary for Policymakers) o Growing evidence indicates that environmental damage from fossil fuel burning will be major and worldwide. Threats to human health and habitats include (See www.ipcc.ch/Climate Change 2001: Impacts, Adaptations and Vulnerability/Summary for Policymakers) o widespread increase in the risk of floods inundating the homes of tens of millions of people, resulting in increased drowning, disease and, in developing countries, hunger; increases, in some geographic areas, in droughts, floods, landslides, storms, and incidences of water-borne (cholera) and vector-borne (malaria) diseases; and irreversible damage to vulnerable ecosystems, with increased risk of extinction of more vulnerable species and loss of biodiversity. o In July 2001, 178 nations signed the Bonn agreement, requiring industrialized nations to reduce greenhouse emissions to 5.2% less than 1990 levels, by 2008. (Wall Street Journal, 7/24/01) o Dupont's CEO stated, "We are preparing our company for a long journey to a more climate- friendly...global economy. We have already reduced our global greenhouse gases by nearly 60%, [and are] committed to...setting new goals for 2010: reducing global carbon-equivalent greenhouse gas emissions by 65% [from 1990 levels]; holding total energy use flat [at 1990 levels]; and using renewable resources for 10% of our global energy use." (11/00) o Major automakers are developing alternative non-combustion engines and technologies to reduce vehicles' fossil fuel demands. Ford's Chairman has said, "We are committed to an improvement in fuel economy for all of our vehicles... [and] a reduction in carbon dioxide emissions. We know greenhouse gases and global temperatures are increasing." (4/14/00) o Royal Dutch/Shell and BP have invested in renewables for years. Royal Dutch/Shell added a penalty of $5/ton of carbon produced when evaluating investment returns on new projects, anticipating more stringent carbon-related regulatory regimes. (Financial Times, 9/12/00) o Companies with top-rated environmental records are faring significantly better financially than those with worse records. From 1997-2000, they had 3.53% higher annual returns on investment than a broader universe of companies, and 7.80% higher annual returns than companies with low-rated' environmental records. (QED International, 2001) o Thirty-nine top religious leaders stated, "... global warming is a scientific fact .... More investment in renewable energy and fuel efficiency is now a moral imperative, especially because these are technologically feasible and economically viable." (National Council of Churches, 5/21/01) 23

[OXY LOGO]---------------------------------------------------------------------- o We believe that good stewardship of our resources requires that we reduce polluting emissions when possible and prudent. RESOLVED: That the Company report to shareholders (at reasonable cost and omitting proprietary information) by August 2002 on (a) total annual greenhouse gas emissions (i) from our company's own operations and (ii) from its products (as best as the Company can estimate); and (b) an estimate of the feasibility and cost of substantially reducing these emissions, together with an evaluation of whether our Company would need such changes to be made on an industry-wide basis and, if so, how that could be accomplished." THE BOARD OF DIRECTORS' STATEMENT IN OPPOSITION Occidental makes available to its stockholders an Annual Report on Health, Environment and Safety (the "HES Report"). In the HES Report for 2000, Occidental explained that it is monitoring the global warming issue, provided an estimate of Occidental's carbon dioxide emissions from its worldwide operations and described some of the measures that the Company has implemented to improve the energy efficiency of its operations. To the extent that there are legislative changes related to the global warming issue that materially impact how Occidental conducts its business or the products it sells, Occidental will discuss those impacts either in its annual HES report or in its annual and quarterly reports filed with the Securities and Exchange Commission. An additional report of the type requested by the proponent would be duplicative and unnecessary. Moreover, the Board believes that, given the lack of consensus within the scientific community regarding the climate change issue and the lack of economically viable substitutes for fossil fuels to satisfy the world's energy needs, any special report attempting to quantify potential financial effects on Occidental would be entirely speculative and, consequently, of little, if any, value. Occidental is not in a position to assess the costs of compliance with legislation that has not been enacted, or potential damages to as yet unknown parties. Accordingly, the Board of Directors recommends a vote AGAINST Proposal 3. Proxies solicited by the Board of Directors will be so voted unless stockholders specify otherwise in the proxy card. STOCKHOLDER PROPOSALS FOR THE 2003 ANNUAL MEETING OF STOCKHOLDERS ------------ Stockholders interested in submitting a proposal for inclusion in the proxy statement and proxy card relating to the 2003 Annual Meeting of Stockholders may do so by following the procedures in Rule 14a-8 under the Securities Exchange Act of 1934. To be eligible for inclusion, stockholder proposals must be addressed to Occidental's Secretary at 10889 Wilshire Boulevard, Los Angeles, California 90024, and be received no later than November 19, 2002. Under Occidental's By-laws, stockholders must follow certain procedures to introduce an item of business at an annual meeting that is not included in the proxy materials. These procedures provide that an item of business to be introduced at an annual meeting must be submitted in writing to the Secretary at 10889 Wilshire Boulevard, Los Angeles, California 90024. Notice of the proposed item of business must be received no later than January 31, 2003. Notice of the proposed item of business must include the information required by Occidental's By-laws. In either case, the stockholder submitting the proposal or a representative of the stockholder must present the proposal in person at the meeting. The chairman of the meeting may refuse to allow the transaction of any item of business not presented in compliance with Occidental's By-laws. In addition, the proxies solicited on behalf of the Board of Directors will have discretionary authority to vote against any such item of business. 24

- -------------------------------------------------------------------------------- NOMINATIONS FOR DIRECTORS FOR TERM EXPIRING 2004 ------------ The Nominating and Corporate Governance Committee will consider nominees recommended by stockholders if the stockholder recommendations are forwarded to the Secretary of Occidental and are otherwise in compliance with Occidental's By-laws. Under Occidental's By-laws, nominations for directors, other than those made by the Board of Directors, must be received 70 to 90 days prior to the anniversary date of the prior year's annual meeting. If the meeting date is not within 30 days of the anniversary date, the nomination must be received not later than the tenth day following the earlier of the day on which the notice of the meeting date was mailed or the day public disclosure of the new date was made. The stockholder's nomination must include the information required by the By-laws. CORPORATE GOVERNANCE POLICIES ------------ A copy of Occidental's corporate governance policies or Occidental's Code of Business Conduct is available upon request by writing to Occidental. ANNUAL REPORT ------------ Occidental's 2001 Annual Report on Form 10-K is concurrently being mailed to stockholders. The Annual Report contains consolidated financial statements of Occidental and its subsidiaries and the report thereon of Arthur Andersen LLP, independent public accountants. Sincerely, /s/ DONALD P.
