- -------------------------------------------------------------------------------- Statements in this presentation that contain words such as "will" or "expect", or otherwise relate to the future, are forward-looking and involve risks and uncertainties that could significantly affect expected results. Factors that could cause results to differ materially include, but are not limited to: global commodity pricing fluctuations, and supply/demand considerations, for oil, gas and chemicals; higher-than-expected costs; and not successfully completing (or any material delay in) any expansion, capital expenditure, acquisition, or disposition. Occidental disclaims any obligation to update any forward-looking statements. - -------------------------------------------------------------------------------- 31

- -------------------------------------------------------------------------------- Return on Capital Employed (ROCE) [OXY LOGO] Reconciliation to Generally Accepted Accounting Principles (GAAP) Annual Average 2000-2002 ($ Millions) -------------- GAAP measure - earnings applicable to common stockholders ------------------------- $ 1,238 Interest Expense --------------------------------- 393 Tax effect of interest expense ------------------- (138) Earnings before tax-effected interest expense ---- $ 1,493 GAAP average stockholders' equity ---------------- $ 5,575 Average debt GAAP debt Notes payable -------------------------------- $ 18 Debt, including current maturities ----------- 3,937 Non-GAAP debt Capital lease obligation --------------------- 26 Subsidiary preferred stock ------------------- 25 Gas sale agreements -------------------------- 231 Trust preferred securities ------------------- 464 Non-recourse debt ---------------------------- 633 Average total debt ------------------------------- $ 5,334 Total average capital employed ------------------- $ 10,909 ROCE --------------------------------------------- 13.7% - -------------------------------------------------------------------------------- o Return on capital employed (ROCE) is calculated by dividing earnings applicable to common shares, before interest expense, by average capital employed (average debt plus equity); interest is added back after-tax (using a 35% statutory rate, not the effective rate). o Occidental management considers ROCE a useful measure because it indicates the return on all capital, both debt and equity, employed in the business. Occidental management believes that ROCE is an additional measure of efficiency when used in conjunction with Return on Equity, which measures the return on only the shareholders' equity portion of the total capital employed.

The result is then divided by the BOE sale volumes. o Occidental management believes that free cash flow per BOE is a useful measure to show the net cash results of the Oil and Gas operation on a per barrel basis. This measure is useful to compare the performance among companies of varying sizes.
