REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Occidental Petroleum Corporation Pension and Retirement Plan Administrative Committee: We have audited the accompanying statements of net assets available for benefits of the Occidental Petroleum Corporation Savings Plan (the Plan) as of December 31, 2003 and 2002 and the related statements of changes in net assets available for benefits for the years then ended. These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (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 benefits of the Plan as of December 31, 2003 and 2002 and the changes in net assets available for benefits for the years then ended in conformity with accounting principles generally accepted in the United States of America. Our audits were performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule, schedule H, line 4i - schedule of assets (held at end of year), 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. This supplemental schedule is the responsibility of the Plan's management. The supplemental schedule has been subjected to the auditing procedures applied in the audits 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:/KPMG/ Los Angeles, California May 21, 2004

OCCIDENTAL PETROLEUM CORPORATION SAVINGS PLAN Notes to Financial Statements December 31, 2003 and 2002 (1) DESCRIPTION OF THE PLAN The following description of the Occidental Petroleum Corporation Savings 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 generally available to certain employees of Occidental Petroleum Corporation (OPC, Oxy, or the Employer), a Delaware corporation, and participating subsidiaries (collectively, the Company). The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended (ERISA). (b) PLAN ADMINISTRATION The Plan is administered by the OPC Pension and Retirement Trust and Investment Committee (PARTAIC) as to investment decisions and by the OPC Pension and Retirement Plan Administrative Committee (PARPAC) as to all matters except investment decisions (these two committees are herein referred to collectively as the Committees). Members of the Committees are selected by the board of directors of OPC. The Committees have been given all powers necessary to carry out their respective duties, including, 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 the trustee and custodian of a trust fund, which holds all of the assets of the Plan. (c) CONTRIBUTIONS Participant Contributions - Participants may contribute up to 15% of compensation (as defined) to the Plan on a before- or after-tax basis, or in any combination thereof, subject to certain Internal Revenue Code (IRC) limitations. Effective July 1, 2002, this deferral percentage limit was increased to 34% of compensation (as defined) for a non Highly Compensated Employee (HCE) and up to 14% for HCEs. Effective January 1, 2003, the deferral percentage limit for non-HCEs changed to 31%, and remained at 14% for HCEs. Effective January 1, 2003 and June 1, 2002, participants age 50 or older by December 31 at the end of the Plan year were permitted to contribute before-tax catch-up contributions to the Plan up to $2,000 and $1,000 for each Plan year, respectively. Employer Contributions - For noncollective bargaining employees, the Company contributed 100% of a participant's contribution up to the first 6% of compensation. For collective bargaining employees, the Company contributed 50%, 75%, or 100% as negotiated by their respective unions, of the first 6% of eligible compensation that a participant contributed to the Plan. All Employer contributions are invested in the Occidental Petroleum Corporation Common Stock Fund (the Oxy Stock Fund). 4 (Continued)

OCCIDENTAL PETROLEUM CORPORATION SAVINGS PLAN Notes to Financial Statements December 31, 2003 and 2002 (d) PARTICIPANT ACCOUNTS Each participant's account is credited with the participant's contribution and allocations of the Company's contribution and Plan earnings, and charged with an allocation of administrative expenses and investment losses. Allocations are based on participant earnings or 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 are vested immediately in their contributions plus actual earnings thereon. Effective June 1, 2002, participants became 100% vested in dividends credited to their balance in the Company Matching Contribution Account under the Oxy Stock Fund on or after June 1, 2002. Vesting in the Company's contribution portion of their accounts is based on years of continuous service. Generally, a participant is 20% vested for each year of service and is 100% vested after five years of credited service. (f) PARTICIPANT LOANS Participants may borrow from their fund 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 during the preceding 12 months, (ii) 50% of their account balance, or (iii) a loan amount which would require payroll deductions for repayment equal to 25% of the participant's base compensation. Loan terms range from one to five years for general-purpose loans and six to ten years for primary residence loans. The loans are secured by the balance in the participant's account and 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. Interest rates ranged from 3.0% to 7.0% on loans outstanding as of December 31, 2003. Principal and interest is paid ratably through monthly payroll deductions. (g) DISTRIBUTIONS Generally, on termination of service for any reason other than death, participants with an account balance greater than $5,000 may elect to receive the vested portion of their account under one of 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 distribution, or (vi) deferral of payment with certain restrictions. Upon termination of service due to death, the beneficiary may elect to receive the vested interest in the form of (i), (ii), (iii), or (vi) only. A participant whose vested account balance is $5,000 or less may receive distributions only under options (i), (v), or (vi). Participants may elect to receive distributions from their account balance in the Oxy Stock Fund in cash or in shares of OPC common stock. (h) FORFEITED ACCOUNTS Forfeited nonvested accounts are used to reduce Employer contributions. During 2003 and 2002, Employer contributions were reduced by approximately $186,000 and $286,000 from forfeited nonvested accounts, respectively. Unallocated forfeitures at December 31, 2003 and 2002 were not significant to the financial statements. 5 (Continued)

OCCIDENTAL PETROLEUM CORPORATION SAVINGS PLAN Notes to Financial Statements December 31, 2003 and 2002 (i) INVESTMENT OPTIONS The Plan offers various investment options which are managed by several outside investment managers. Upon enrollment in the Plan, participants may direct their contributions, in 1% increments, in any of the investment options offered at the time. Participants may change their investment options daily. Participants should refer to the Plan fund description pamphlet for a complete description of the investment options and for the detailed composition of each investment fund. (j) PLAN AMENDMENTS Effective June 1, 2002, the Plan was amended to designate the Matching Account held under the Plan as an employee stock ownership plan and to allow participants the option to have dividends reinvested in the Oxy Stock Fund or distributed in the form of cash. (k) PLAN MERGERS Effective September 12, 2003, all accounts that would not be distributed from the Oxy Permian Savings Plan, which was terminated effective March 31, 2002, were merged into the Plan. Approximately $1,553,000 was transferred into the Plan in September 2003. Effective February 28, 2002, the Oxy Vinyls, LP Savings Plan was merged into the Plan. As a result of the merger, the Plan became a multiple-employer plan. In March 2003, Oxy Vinyls LP employees transferred to Oxy Vinyls Services, Inc. As a result, the Plan is no longer a multiple-employer plan. (2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (a) BASIS OF ACCOUNTING The financial statements of the Plan are prepared under the accrual method of accounting. Certain reclassifications have been made to the 2002 financial statements to be consistent with the current year presentation. (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 and liabilities and changes therein, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates. (c) INVESTMENT VALUATION AND INCOME RECOGNITION The Plan's investments are stated at fair value except for the investments in guaranteed investment contracts (fully benefit-responsive investment contracts) which are valued at contract value (notes 3 and 5). Quoted market prices are used to value investments. Shares of mutual funds are valued at the net asset value of shares held by the Plan at year-end. 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 an accrual basis. Dividends are recorded on the ex-dividend date. 6 (Continued)

OCCIDENTAL PETROLEUM CORPORATION SAVINGS PLAN Notes to Financial Statements December 31, 2003 and 2002 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 of 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 value at the end of the year. Net realized and unrealized appreciation (depreciation) in fair value of investments is reflected in the accompanying statement of changes in net assets available for benefits as "net appreciation (depreciation) in fair value of investments." (d) PAYMENT OF BENEFITS Benefits are recorded when paid. (e) RISKS AND UNCERTAINTIES The Plan invests in various types of investment securities, including mutual funds, actively managed funds, and the Oxy Stock Fund. Investment securities are exposed to various risks, such as interest rate, market, and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect the amounts reported in the statements of net assets available for benefits. 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. As of December 31, 2003 and 2002, approximately 43% and 39% of total Plan investments, respectively, were invested in the Oxy Stock Fund. 7 (Continued)

During 2003 and 2002, the Plan's investments (including gains and losses on investments bought and sold, as well as held during the year) appreciated (depreciated) in value by approximately $243,835,000, and $(48,343,000), respectively, as follows (dollar amounts in thousands): 2003 2002 ---------------- ---------------- Common stocks $ 164,188 11,281 Mutual funds 79,080 (59,417) Interest in master trust 567 (207) ---------------- ---------------- $ 243,835 (48,343) ================ ================ 8 (Continued)

OCCIDENTAL PETROLEUM CORPORATION SAVINGS PLAN Notes to Financial Statements December 31, 2003 and 2002 (4) OXY STOCK FUND Information regarding the net assets and the significant components of the changes in net assets relating to the Oxy Stock Fund, which includes both participant- and nonparticipant-directed investments is as follows (dollar amounts in thousands): DECEMBER 31 --------------------------------------- 2003 2002 ---------------- ---------------- Net assets: Oxy Stock Fund $ 457,576 330,778 YEAR ENDED DECEMBER 31 --------------------------------------- 2003 2002 ---------------- ---------------- Changes in net assets: Contributions $ 24,724 26,890 Investment income 11,415 11,486 Net appreciation in fair value of investments 149,051 20,674 Transfers between funds (13,557) (9,799) Benefits paid to participants (44,745) (36,601) Administrative expenses (90) (82) Transfer from other plan -- 44,517 ---------------- ---------------- $ 126,798 57,085 ================ ================ (5) GUARANTEED INVESTMENT CONTRACTS The Invesco Fixed-Income Fund (the Fund) includes investments in guaranteed investment contracts (GICs) and synthetic GICs. Both the Plan and the OPC Retirement Plan are invested in the Fund, managed by Invesco. The Plan's investment in the Fund is 41.45% and 40.64% at December 31, 2003 and 2002, respectively. The Plan's investments in GICs are included in the statements of net assets available for 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. Withdrawals resulting from events initiated by the Company, such as Plan termination, are not typically considered participant-initiated transactions. With such an event, some of the contracts contain contingencies that could lead to withdrawal penalties. However, since no such events are being contemplated at this time or the withdrawals resulting from such an event will be funded outside the contracts' provisions, these "potential" limitations do not jeopardize the contract value reporting for these investments. 9 (Continued)

OCCIDENTAL PETROLEUM CORPORATION SAVINGS PLAN Notes to Financial Statements December 31, 2003 and 2002 Contract value for the synthetic GICs is determined based on the fair value of the assets underlying the synthetic GICs. The difference between the fair value of the assets underlying the synthetic GICs and the contract value of the GICs is the value of the "wrapper" contract issued by a third party. The fair value for GICs varies based on the type of contract held (e.g., security-backed investments and general account investments). Fair value of the general account investment type GICs is derived by comparing the contract value, on a duration basis, to the yield curve. Fair value of the nonparticipating synthetic GICs is determined by comparing each contract, on a duration basis, to a Treasury yield curve at year-end, plus 40 basis points. Fair value for security-backed investment contracts was derived from outside sources, based on the type of investment held. GICs provide a fixed crediting interest rate, and a financially responsible entity guarantees liquidity at contract value prior to maturity for any and all participant-initiated benefit withdrawals, loans, or transfers arising under the terms of the Plan, which allows access for all participants. Synthetic GICs operate similarly to a separate account guaranteed investment contract, except that the assets are placed in a trust with ownership by the Plan rather than a separate account of the issuer and a financially responsible third party issues a wrapper contract that provides that participants can, and must, execute Plan transactions at contract value. Inasmuch as trust assets are owned by the Plan, the wrapper contract and the assets in trust are separately valued and disclosed. The wrapper contract is valued at the difference between the fair value of the trust assets and the contract value attributable by the wrapper to such assets. When considered together, the trust assets and the wrapper contract are reported at the wrapper contract value because participants are guaranteed return of principal and accrued interest. During 2003 and 2002, the average yield earned on amounts invested in the GICs was 4.69% and 5.52%, respectively. As of December 31, 2003 and 2002, the average crediting interest rate on such contracts was 4.73% and 4.97%, respectively. There were no valuation reserves recorded to adjust contract amounts during the Plan years. Crediting rate resets are applied to specific investment contracts, as determined at the time of purchase. The reset values for security-backed investment rates are a function of contract value, 10 (Continued)

OCCIDENTAL PETROLEUM CORPORATION SAVINGS PLAN Notes to Financial Statements December 31, 2003 and 2002 (6) INVESTMENT IN MASTER TRUST The Plan's investment assets include a convertible bond fund in which other plans also invest. This convertible bond fund is managed by Advent Capital Management and is one of the master trust investment accounts (Advent MTIA) in the OPC Master Retirement Trust. At December 31, 2003 and 2002, the Plan's investment in the assets of Advent MTIA represented an individual interest of approximately 15% and 10%, respectively. The following table presents the aggregate fair value of investments held by, and investment income earned by, the Advent MTIA, in which the Plan owns an undivided interest, as stated above (dollar amounts in thousands): DECEMBER 31 --------------------------------------- 2003 2002 ---------------- ---------------- Investments at fair value as determined by quoted market price: Common/collective trust $ -- 156 Preferred stock 6,974 5,766 Corporate bonds 15,713 11,031 ---------------- ---------------- $ 22,687 16,953 ================ ================ YEAR ENDED DECEMBER 31 --------------------------------------- 2003 2002 ---------------- ---------------- Investment income (loss): Net appreciation (depreciation) in fair value of investments: Common stock $ -- (161) Preferred stock 1,209 (1,482) Corporate bonds 2,827 (1,001) ---------------- ---------------- 4,036 (2,644) Income from common/collective trust -- 2 Interest and dividends 710 689 Less investment expenses (171) (203) ---------------- ---------------- $ 4,575 (2,156) ================ ================ (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.

OCCIDENTAL PETROLEUM CORPORATION SAVINGS PLAN Notes to Financial Statements December 31, 2003 and 2002 (8) PLAN TERMINATION Although it has not expressed any intent to do so, the Company 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 would become 100% vested in their Employer contributions. (9) TAX STATUS The Internal Revenue Service has determined and informed the Company by a letter dated February 24, 2003, that the Plan and related trust are designed in accordance with applicable sections of the IRC.
