INDEPENDENT AUDITORS' REPORT The Occidental Petroleum Corporation Pension and Retirement Plan Administrative Committee: We have audited the accompanying statement of net assets available for benefits of the Oxy Vinyls, LP Savings Plan as of December 31, 2001, and the related statement of changes in net assets available for benefits 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 audit. The accompanying financial statements of the Oxy Vinyls, LP Savings Plan as of December 31, 2000 were audited by other auditors whose report thereon dated June 22, 2001, expressed an unqualified opinion on those statements. We conducted our audit 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 audit provides a reasonable basis for our opinion. In our opinion, the 2001 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 December 31, 2001 and the changes in net assets available for benefits for the year ended December 31, 2001 in conformity with accounting principles generally accepted in the United States of America. Our audit was performed for the purpose of forming an opinion on the 2001 basic financial statements taken as a whole. The supplemental schedule, Schedule H, Line 4i - Schedule of Assets (Held at End of Year) as of December 31, 2001 is presented for the purpose of additional analysis and is not a required part of the 2001 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 audit of the 2001 basic financial statements and, in our opinion, is fairly stated, in all material respects, in relation to the 2001 basic financial statements taken as a whole. /s/ KPMG LLP Los Angeles, California June 20, 2002

OXY VINYLS, LP SAVINGS PLAN Notes to Financial Statements December 31, 2001 and 2000 (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 is 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 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 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 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 the trustee and custodian of a trust fund which holds all of the assets of the Plan. (c) CONTRIBUTIONS PARTICIPANT CONTRIBUTIONS - Prior to June 30, 2000, participants were allowed to contribute from 1% to 12% 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, 2000, the upper limit on participant contributions increased from 12% to 15%. EMPLOYER CONTRIBUTIONS - Prior to June 30, 2000, the Employer contributed 75% of a participant's contribution up to the first 6% of compensation. Effective July 1, 2000, Employer contributions increased to 100% of a participant's contribution up to the first 6% of compensation. All Employer contributions are invested in the Occidental Petroleum Corporation Common Stock Fund (the Oxy Stock Fund). (d) INVESTMENT OPTIONS The Plan offers 11 investment options. Upon enrollment in the Plan, participants can direct their contributions, in 5% increments, in any of the investment options offered at the time. Participants can 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. 4 (Continued)

OXY VINYLS, LP SAVINGS PLAN Notes to Financial Statements December 31, 2001 and 2000 (e) PARTICIPANT ACCOUNTS Participant 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. (f) VESTING Participants immediately vest in their contributions plus investment income thereon, if any. Vesting in the Employer's contribution portion of the account plus earnings thereon, is based on years of service. Generally, a participant receives 20% vesting for each year of service and is fully vested after five years of service. Participants who were eligible to participate in the Plan on May 1, 1999 were fully vested. (g) PARTICIPANT LOANS Participants can 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 are treated as a transfer between the investment fund and the participant loan fund. Loan terms range from one to five years for general purpose loans and six to ten years for primary residence loans. 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. During 2001 and 2000, the interest rate charged on new loans was 5%. Loan repayments are made ratably through payroll deductions. (h) PAYMENT OF BENEFITS Generally, upon termination of service for any reason other than death, participants with an account balance greater than $5,000 can 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 can elect to receive the vested interests in the form of (i), (ii), (iii), or (vi) only. A participant whose vested account balance is $5,000 or less can receive distributions only under options (i), (v), or 5 (Continued)

OXY VINYLS, LP SAVINGS PLAN Notes to Financial Statements December 31, 2001 and 2000 (vi). Participants can elect to receive distributions from their account balance in the Oxy Stock 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. (i) FORFEITED ACCOUNTS Forfeited nonvested accounts are used to reduce Employer contributions. (j) ADMINISTRATIVE EXPENSES The Company pays certain costs and expenses incurred in administering the Plan and other costs and expenses are paid by the 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 2000 financial statements to be consistent with the presentation of the 2001 financial statements. (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 provides 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 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 involve 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. 6 (Continued)

OXY VINYLS, LP SAVINGS PLAN Notes to Financial Statements December 31, 2001 and 2000 (d) INVESTMENT VALUATION AND INCOME RECOGNITION The Plan's investments are stated at fair 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 OPC common stock, PolyOne common stock, and BFGoodrich common stock (see note 3) are valued at their quoted market prices. The unit price of common or commingled trust funds is based on the current market value of the underlying assets of the fund. 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 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 are 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 Statement of Changes in Net Assets Available for Benefits as "Net (depreciation) in fair value of investments." (e) PAYMENT OF BENEFITS Benefits are recorded when paid. 7 (Continued)

This investment is part of a master trust. The Plan's interest in the master trust investment loss as reflected in the Statement of Changes in Net Assets Available for Benefits for the year ended December 31, 2001 represents the period for which the Plan participated in the master trust. At December 31, 2001, the Plan's investment in the assets of the Master Trust represented an undivided interest of approximately 1%. 9 (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 year ended December 31, 2001, the Plan paid the Trustee $114,464 for services provided under the trust agreement. 11 (Continued)

OXY VINYLS, LP SAVINGS PLAN Notes to Financial Statements December 31, 2001 and 2000 (8) PLAN TERMINATION 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 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 are designed in accordance with applicable sections of the IRC. Although the Plan has been amended since receiving the determination letter, the Committees believe that the Plan is designed and currently being operated in compliance with the applicable requirements of the IRC. (10) SUBSEQUENT EVENT 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. 12

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Oxy Vinyls, LP Pension and Retirement
  Plan Administrative Committee:


We have audited the accompanying statements of net assets available for plan
benefits of the OXY VINYLS, LP SAVINGS 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 schedules referred to below are the responsibility of the Plan
administrator. Our responsibility is to express an opinion on these financial
statements and supplemental schedules 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.

- -------------------------------------------------------------------------------- THIS REPORT IS A COPY OF A PREVIOUSLY ISSUED ANDERSEN REPORT AND THAT THE REPORT HAS NOT BEEN REISSUED BY ANDERSEN. - -------------------------------------------------------------------------------- Our audit was made for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedules included in appendices I and II, as listed in the accompanying index, are presented for purposes of additional analysis and are not a required part of the basic financial statements but are 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.
