INDEPENDENT AUDITORS' REPORT The Occidental Petroleum Corporation Pension and Retirement Plan Administrative Committee: We have audited the accompanying statements of net assets available for benefits of the Oxy Vinyls, LP Savings Plan as of February 28, 2002 and December 31, 2001, and the related statements of changes in net assets available for benefits for the period ended February 28, 2002 and for the year ended December 31, 2001. 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 auditing standards generally accepted in the United States of America. 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 Oxy Vinyls, LP Savings Plan as of February 28, 2002 and December 31, 2001 and the changes in net assets available for benefits for the period ended February 28, 2002 and for the year ended December 31, 2001 in conformity with accounting principles generally accepted in the United States of America. /s/ KPMG LLP Los Angeles, California June 20, 2002

OXY VINYLS, LP SAVINGS PLAN Notes to Financial Statements February 28, 2002 and December 31, 2001 (1) DESCRIPTION OF THE PLAN The following description of the Oxy Vinyls, LP Savings Plan (Plan) provides only general information. Participants should refer to the Plan document for a more complete description of the Plan's provisions. (a) GENERAL Occidental Chemical Corporation (OxyChem), a wholly owned subsidiary of Occidental Petroleum Corporation (OPC or Oxy), a Delaware corporation, and The Geon Company (Geon) caused a partnership to be formed, Oxy Vinyls, LP, a Delaware limited partnership, and selected affiliates (collectively, the Company or the Employer), in which OxyChem and Geon have indirect interests of 76% and 24%, respectively. The Plan was a defined contribution plan generally available to certain employees of the Company. The Plan was established by the Company effective May 1, 1999. The Plan was subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended (ERISA). (b) MERGER OF PLAN INTO SUCCESSOR PLAN The Plan was merged into the Occidental Petroleum Corporation Savings Plan (PSA) with an effective date of February 28, 2002. Plan participants became participants in the PSA plan and their participant accounts and the plan assets were transferred into the PSA plan effective as of February 28, 2002. The transfer is reflected in the Statements of Changes in Net Assets Available for Benefits for the period ended February 28, 2002 as "Transfer to successor plan." (c) PLAN ADMINISTRATION Prior to the Merger, the Plan was administered by the OPC Pension and Retirement Trust and Investment Committee as to investment decisions and by the Oxy Vinyls, LP Pension and Retirement Plan Administrative Committee as to all matters except investment decisions (these two committees are herein referred to collectively as the Committees). The Committees had 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) was the trustee and custodian of a trust fund which held all of the assets of the Plan. (d) CONTRIBUTIONS PARTICIPANT CONTRIBUTIONS - Participants were allowed to contribute from 1% 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. EMPLOYER CONTRIBUTIONS - The Employer contributed 100% of a participant's contribution up to the first 6% of compensation. All Employer contributions were invested in the Occidental Petroleum Corporation Common Stock Fund (the Oxy Stock Fund). 4 (Continued)

OXY VINYLS, LP SAVINGS PLAN Notes to Financial Statements February 28, 2002 and December 31, 2001 (e) INVESTMENT OPTIONS Prior to the Merger, the Plan offered 11 investment options. Upon enrollment in the Plan, participants could direct their contributions, in 5% increments, in any of the investment options offered at the time. Participants could 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. (f) PARTICIPANT ACCOUNTS Participant accounts were 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 were based on account balances, as defined. The benefit to which a participant was entitled was the benefit that could be provided from the participant's vested account. (g) VESTING Participants immediately vested in their contributions plus investment income thereon, if any. Vesting in the Employer's contribution portion of the account plus earnings thereon, was based on years of service. Generally, a participant received 20% vesting for each year of service and was fully vested after five years of service. Participants who were eligible to participate in the Plan on May 1, 1999 were fully vested. (h) PARTICIPANT LOANS Participants could borrow from their account 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 12 months, (ii) 50% of their vested account balance, or (iii) a loan amount which would require payroll deductions for repayment equal to 25% of the participant's base compensation. Loan transactions were treated as a transfer between the investment fund and the participant loan fund. Loan terms ranged from one to five years for general purpose loans and six to ten years for primary residence loans. The loans bore 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 was approved. During 2002 and 2001, the interest rate charged on new loans was 5%. Loan repayments were made ratably through payroll deductions. (i) PAYMENT OF BENEFITS Generally, upon termination of service for any reason other than death, participants with an account balance greater than $5,000 could 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 termination of service due to death, the participant's beneficiary could elect to receive the vested interests in the form of (i), (ii), (iii), or (vi) only. A participant whose vested account balance was $5,000 or less could receive distributions only under options (i), (v), or (vi). Participants could elect to receive distributions from their account balance in the Oxy Stock 5 (Continued)

OXY VINYLS, LP SAVINGS PLAN Notes to Financial Statements February 28, 2002 and December 31, 2001 Fund, the PolyOne Stock Fund (formerly the Geon Stock Fund), or the BFGoodrich Stock Fund in cash or in shares of common stock of such company. (j) FORFEITED ACCOUNTS Forfeited nonvested accounts were used to reduce Employer contributions. (k) ADMINISTRATIVE EXPENSES The Company paid certain costs and expenses incurred in administering the Plan and other costs and expenses were paid by the Plan. (2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (a) BASIS OF ACCOUNTING The financial statements of the Plan were 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 of America 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) RISKS AND UNCERTAINTIES The Plan provided for various investment options in mutual funds, actively managed funds, the Oxy Stock Fund, the PolyOne Stock Fund, and the BFGoodrich Stock Fund. Investment securities were 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 was 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 invested in the securities of foreign companies, which involved special risks and considerations not typically associated with investing in U.S. companies. These risks included 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 were 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 were prohibited. 6 (Continued)

OXY VINYLS, LP SAVINGS PLAN Notes to Financial Statements February 28, 2002 and December 31, 2001 (d) INVESTMENT VALUATION AND INCOME RECOGNITION The Plan's investments were stated at fair value. Shares of registered investment companies were valued at quoted market prices, which represented the net asset value of shares held by the Plan at year-end. The OPC common stock, PolyOne common stock, and BFGoodrich common stock (see note 3) were valued at their quoted market prices. The unit price of common or commingled trust funds was based on the current market value of the underlying assets of the fund. Participant loans were valued at cost, which approximated fair value. Purchases and sales of securities were recorded on a trade-date basis. Interest income was recorded on the accrual basis. Dividends were 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 Plan year or at the time of purchase for assets purchased during the Plan year and the related fair value on the day the investments were sold during the Plan year. Unrealized gains and losses on investments were based on the market value of the assets at the beginning of the Plan year or at the time of purchase for assets purchased during the Plan year and the related fair value at the end of the Plan year. Net realized and unrealized appreciation/(depreciation) in fair value of investments is reflected in the accompanying Statements of Changes in Net Assets Available for Benefits as "Net (depreciation) in fair value of investments." (e) PAYMENT OF BENEFITS Benefits were recorded when paid. (3) INVESTMENTS The following presents investments, with those that represent 5% or more of the Plan's net assets separately identified: FEBRUARY 28, DECEMBER 31, 2002 2001 -------------- -------------- Common stock: Oxy Stock Fund $ -- 35,770,049* Registered investment companies: Employee Benefit Index Fund -- 14,275,476 Magellan Fund -- 8,716,147 Contrafund -- 7,843,019 Balanced Fund -- 5,352,957 Common/collective trust: Stable Value Fund -- 18,584,383 All other investments less than 5% -- 9,699,469 -------------- -------------- $ -- 100,241,500 ============== ============== * Participant and nonparticipant-directed 7 (Continued)

OXY VINYLS, LP SAVINGS PLAN Notes to Financial Statements February 28, 2002 and December 31, 2001 During 2002 and 2001, the Plan's investments (including investments bought, sold, and held during the year) depreciated in value by $794,524 and $669,901, respectively, as follows: PERIOD ENDED YEAR ENDED FEBRUARY 28, DECEMBER 31, 2002 2001 -------------- -------------- Common stock $ 440,961 3,416,779 Registered investment companies (1,235,485) (4,086,680) -------------- -------------- $ (794,524) (669,901) ============== ============== (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 included both participant and nonparticipant-directed investments were as follows: FEBRUARY 28, DECEMBER 31, 2002 2001 -------------- -------------- Net assets: Oxy Stock Fund $ -- 36,802,277 PERIOD ENDED YEAR ENDED FEBRUARY 28, DECEMBER 31, 2002 2001 -------------- -------------- Changes in net assets: Contributions $ 450,347 3,963,622 Investment income 2,362 1,351,039 Net appreciation in fair value 408,756 2,911,027 Transfers between funds (421,428) (493,351) Plan expenses (9,989) (54,301) Benefits paid to participants (420,702) (2,480,921) Transfer to successor plan (36,811,623) -- -------------- -------------- $ (36,802,277) 5,197,115 ============== ============== (5) INTEREST IN MASTER RETIREMENT TRUST During 2001, an investment option was added to the Plan. This investment is part of a master trust. The Plan's interest in the master trust investment loss as reflected in the Statements of Changes in Net Assets Available for Benefits for the period ended February 28, 2002 and year ended December 31, 2001 represents the period for which the Plan participated in the master trust. 8 (Continued)

(7) PARTY-IN-INTEREST TRANSACTIONS The Trustee, Oxy Vinyls, LP and OPC are parties-in-interest as defined by ERISA. The Trustee invests certain Plan assets in its collective short-term investment fund, the Oxy Stock Fund, the PolyOne Stock Fund, and the BFGoodrich Stock Fund. Such transactions qualify as party-in-interest transactions permitted by Department of Labor regulations. For the period ended February 28, 2002 and for the year ended December 31, 2001, the Plan paid the Trustee $2,500 and $114,464, respectively, for services provided under the trust agreement. 10 (Continued)

OXY VINYLS, LP SAVINGS PLAN Notes to Financial Statements February 28, 2002 and December 31, 2001 (8) PLAN TERMINATION Prior to the Merger date, the Company had 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 accounts. (9) TAX STATUS The Internal Revenue Service has determined and informed the Company by letters dated January 30, 2002 and August 3, 2000, that the Plan and related trust were designed in accordance with applicable sections of the IRC. Although the Plan had been amended since receiving the determination letter, the Committees believed that the Plan was designed and operated in compliance with the applicable requirements of the IRC. 11
