REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS To the Occidental Chemical Corporation Pension and Retirement Plan Administrative Committee: We have audited the accompanying statements of net assets available for plan benefits of the OCCIDENTAL CHEMICAL CORPORATION SAVINGS AND INVESTMENT PLAN (the "Plan") as of December 31, 2000 and 1999, and the related statement of changes in net assets available for plan benefits for the year ended December 31, 2000. These financial statements and the supplemental schedule referred to below are the responsibility of the Plan administrator. Our responsibility is to express an opinion on these financial statements and supplemental schedule based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for plan benefits of the Plan as of December 31, 2000 and 1999, and the changes in its net assets available for plan benefits for the year ended December 31, 2000, in conformity with accounting principles generally accepted in the United States.

Our audit was made for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule of assets held for investment purposes, is presented for purposes of additional analysis and is not a required part of the basic financial statements but is supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. The supplemental schedule has been subjected to the auditing procedures applied in the audit of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole. /s/ ARTHUR ANDERSEN LLP ARTHUR ANDERSEN LLP Los Angeles, California June 22, 2001

OCCIDENTAL CHEMICAL CORPORATION SAVINGS AND INVESTMENT PLAN Notes to Financial Statements December 31, 2000 and 1999 1. Description of the Plan The following description of the Occidental Chemical Corporation Savings and Investment Plan (the "Plan") provides only general information. Participants should refer to the Plan document for a more complete description of the Plan's provisions. a. General The Plan is a defined contribution plan established for eligible employees of Occidental Chemical Corporation ("OxyChem", "the Company", or the "Employer"), a wholly-owned subsidiary of Occidental Petroleum Corporation ("OPC" or "Oxy"), a Delaware corporation. It is subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended ("ERISA"). Generally, employees of OxyChem are eligible to participate in the Plan if they (i) are subject to a collective bargaining agreement and (ii) work at an OxyChem location that has negotiated the right to participate in the Plan in a recognized collective bargaining agreement. b. Plan Administration The Plan is administered by the OPC Pension and Retirement Trust and Investment Committee as to investment decisions and by the OxyChem Pension and Retirement Plan Administrative Committee as to all matters except investment decisions (collectively, the "Committees"). The Committees have been given all powers necessary to carry out their respective duties, including as applicable, but not limited to, the power to administer and interpret the Plan and to answer all questions affecting eligibility of participants. The Northern Trust Company (the "Trustee") is trustee and custodian of a trust fund which holds all the assets of the Plan. The Company pays certain costs and expenses incurred in administering the Plan. Such costs and expenses were not significant for the year ended December 31, 2000. c. Contributions Participant Contributions - Participants may contribute from 1 to 12 percent of eligible compensation to the Plan on a before- or after-tax basis or in any combination thereof, subject to certain Internal Revenue Code ("IRC") limitations. Employer Contributions - OxyChem contributes 50 or 75 percent, as negotiated, of the first 6 percent of eligible compensation, as defined in the Plan document, that a participant contributes to the Plan. All Employer contributions are invested in the Occidental Petroleum Corporation Common Stock Fund (the "Oxy Stock Fund"). 5

d. Participant Accounts Participants accounts are credited with the participant's contribution and allocations of the Employer's contribution and investment income, and charged with an allocation of administrative expenses and investment losses, if any. Allocations are based on account balances, as defined. The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested account. e. Vesting Participants immediately vest in their contributions plus actual investment income, if any. Vesting in the Employer's contribution portion of the account plus actual earnings thereon is based on years of service. Generally, a participant receives 20 percent vesting for each year of service until full vesting is achieved after 5 years of service. f. Forfeitures Forfeited nonvested accounts are used to reduce Employer contributions. During 2000, Employer contributions were reduced by $4,518 from forfeited nonvested accounts. Unallocated forfeitures at December 31, 2000 and 1999, were not significant to the financial statements. g. Distributions Generally, upon termination of service for any reason other than death, a participant with an account balance greater than $5,000 may elect to receive the vested portion of their account in the following distribution options: (i) one lump sum payment, (ii) straight life annuity, (iii) ten-year term certain annuity, (iv) joint and survivor annuity, (v) partial cash distributions or (vi) deferral of payment with certain restrictions. Upon the death of a participant, a spousal beneficiary may elect to receive the vested interests in the form of (i), (ii), (iii) or (vi). A non-spousal beneficiary may elect to receive the vested interest in the form of (i), (ii) or (iii). If there are multiple beneficiaries the only form of payment available is a lump sum. A participant whose vested account balance is $5,000 or less may receive distributions only under options (i), (v) or (vi). Participant may elect to receive distributions from their account balance in the Oxy Stock Fund in cash or in shares of OPC common stock. h. Participant Loans Participants may borrow from their accounts a minimum of $1,000 up to a maximum equal to the lesser of: (i) $50,000, reduced by the highest outstanding loan balance in the past twelve months, (ii) 50 percent of their vested account balance, or (iii) a loan amount which would require payroll deductions for repayment equal to 15 percent of the participant's base compensation. Loan transactions are treated as a transfer between the investment fund and the participant loan fund. Loan terms range from 1 to 5 years. 6

During 1999, the interest rate charged on new loans ranged from 5 to 7 percent. During 2000 the interest rate charged on new loans was 5 percent. Loan repayments are made ratably through payroll deductions. The loans bear interest at a fixed rate equal to the Western Federal Credit Union's loan rate for a loan secured by a member's deposit account at the time the loan is approved. i. Investment Options The Plan currently offers 7 investment options. Upon enrollment in the Plan, participants may direct their employee contributions, in 10 percent increments, in any of the investment options. Participants may change their investment options on a monthly basis. Participants should refer to the Plan document for a complete description of the investment options and for the detailed composition of each investment fund. 2. Summary of Significant Accounting Policies a. Basis of Accounting The financial statements of the Plan are prepared under the accrual method of accounting. b. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and changes therein, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates. c. Risk and Uncertainties The Plan provides for various investment options in mutual funds, actively managed funds and the Oxy Stock Fund. Investment securities are exposed to various risks such as interest rate, market and credit. Due to the level of uncertainty related to changes in the value of investment securities, it is at least reasonably possible that changes in the various risk factors, in the near term, could materially affect participants' account balances and the amounts reported in the financial statements. Additionally, many mutual funds invest in the securities of foreign companies, which involves special risks and considerations not typically associated with investing in U.S. companies. These risks include devaluation of currencies, less reliable information about issuers, different securities transaction clearance and settlement practices, and possible adverse political and economic developments. Moreover, securities of many foreign companies and their markets may be less liquid and their prices more volatile than similar types of securities of comparable U.S. companies. Derivative financial instruments are used by the Plan's equity and fixed income investment managers to remain fully invested in the asset class and to hedge currency risk. Leveraging of the Plan assets and speculation are prohibited. 7

d. Investment Valuation and Income Recognition The Plan's investments are stated at fair value except for the investments in guaranteed investment contracts which are valued at contract value. Shares of registered investment companies are valued at quoted market prices, which represent the net asset value of shares held by the Plan at year end. The unit price of common or commingled trust funds is based on the current market value of the underlying assets of the fund. The OPC common stock is valued at its quoted market price. Participant loans are valued at cost, which approximates fair value. Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date. Realized gains and losses on investments are based on the market value of the asset at the beginning of the year, or at the time of purchase for assets purchased during the year, and the related fair value on the day the investments are sold during the year. Unrealized gains and losses on investments are based on the market value of the assets at the beginning of the year, or at the time of purchase for assets purchased during the year, and the related fair values on December 31, 2000. Net realized and unrealized appreciation/(depreciation) of investments is reflected in the accompanying statement of changes in net assets available for plan benefits as "net appreciation in fair value of investments." e. Payment of Plan Benefits Benefits are recorded when paid. 3. Investments The following table presents investments that represent 5 percent or more of the Plan's net assets: December 31, 2000 1999 ------------ ------------ Common Stock: Oxy Stock Fund $ 8,982,379* $ 7,002,833* Mutual Funds: Stock Equity Fund 4,027,773 3,690,175 Balanced Fund 1,613,434 1,101,406 Common/Collective Trust: Stable Value Fund 2,409,481 2,287,508 S&P 500 Index Fund 10,235,937 10,890,802 * Participant and non-participant directed 8

During 2000, the Plan's investments (including investments bought, sold and held during the year) appreciated in value by $755,826 as follows: Common Stock $ 1,260,553 Mutual Funds 367,848 Common/Collective Trust (872,575) ----------- $ 755,826 =========== 4. Oxy Stock Fund Information about the net assets and the significant components of the changes in net assets relating to the Oxy Stock Fund which includes both participant and non-participant directed investments is as follows: December 31, 2000 1999 ------------ ------------ Net Assets: Oxy Stock Fund $ 9,077,002 $ 7,081,349 ============ ============ Year Ended December 31, 2000 ----------------- Changes in Net Assets: Contribution $ 1,114,101 Dividends 351,174 Interest 23,946 Net appreciation in fair value 1,260,553 Transfers between funds (94,622) Benefits paid to participants (659,499) ----------------- $ 1,995,653 ================= 5. Stable Value Contracts The Plan's investments in guaranteed investment contracts are included in the statements of net assets available for plan benefits at contract value (which represents contributions made under the contract plus earnings, less withdrawals and administrative expenses) because they are fully benefit responsive. For example, participants may ordinarily direct the withdrawal or transfer of all or a portion of their investment at contract value. The fair value of the guaranteed investment contracts at December 31, 2000 and 1999 approximates contract value. During 2000 and 1999, the average yield earned on amounts invested in these contracts was 6.34 and 6.30 percent, respectively. As of December 31, 2000 and 1999, the average crediting interest rate on such contracts was 6.22 and 6.33 percent, respectively. 9

6. Reconciliation of the Financial Statement to the Form 5500 The following is a reconciliation of net assets available for plan benefits per the financial statements to the Form 5500: December 31, 2000 1999 ------------ ------------ Net assets available for plan benefits per the financial statements $ 29,668,584 $ 27,033,042 Amounts allocated to withdrawing participants (232,690) (149,645) ------------ ------------ Net assets available for plan benefits per the Form 5500 $ 29,435,894 $ 26,883,397 ============ ============ The following is a reconciliation of benefits paid to participants per the financial statements to the Form 5500: Year Ended December 31, 2000 ----------------- Participant withdrawals and distributions per the financial statements $ 1,982,677 Add: Amounts allocated to withdrawing participants at December 31, 2000 232,690 Less: Amounts allocated to withdrawing participants at December 31, 1999 (149,645) ----------------- Benefits paid to participants per the Form 5500 $ 2,065,722 ================= Amounts allocated to withdrawing participants are recorded on the Form 5500 for benefit payments that have been processed and approved for payment prior to December 31 but not yet paid as of that date. 7. Related Party Transactions The Trustee and OPC are parties-in-interest as defined by ERISA. The Trustee invests certain Plan assets in its collective short-term investment fund and the Oxy Stock Fund. Such transactions qualify as party-in-interest transactions permitted by Department of Labor's regulations. 8. Plan Termination Although it has not expressed any intent to do so, OxyChem has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of Plan termination, participants will become 100 percent vested in their accounts. 10

9. Tax Status The Internal Revenue Service has determined and informed OxyChem by a letter dated May 20, 1996, that the Plan is designed in accordance with applicable sections of the IRC. The Plan has been amended since receiving the determination letter. However, the Committees, using their judgment and the advice of their advisors, believes that the Plan, in all material respects, is designed and currently operating in a manner that qualifies it for continued tax-exempt status. 10. Subsequent Event Effective May 1, 2001, the Pottstown, Pennsylvania union was allowed to participate in the Occidental Petroleum Corporation Savings Plan. 11
