                          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.

          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).

                     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)

          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.

                     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.

     the Plan's net assets separately identified:

     Prior to the Merger on February 28, 2002 and at December 31, 2001, the
     Plan's investment in the assets of the Master Trust represented an
     undivided interest of approximately 1%.

     The following table presents the aggregate fair value of investments held

     Amounts allocated to withdrawing participants were 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.

     The following is a reconciliation of investments per the financial
     statements to the Form 5500 as of February 28, 2002 and December 31, 2001:



                                                                                 FEBRUARY 28,       DECEMBER 31,

     The Plan's interest in the Master Trust is not included in the Form 5500
     since it is not required based on the disclosure requirements of the
     Employee Retirement Income Security Act of 1974 and applicable regulations
     issued by the Department of Labor.

(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.

(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.
