Item 5. Other Events and Regulation FD Disclosure - ------ ----------------------------------------- Occidental Petroleum Corporation announced net income of $402 million ($1.09 per share) for the third quarter of 2000, compared with $126 million ($0.35 per share) for the corresponding period of 1999. Earnings before special items for the quarter were $370 million ($1.00 per share) compared with earnings before special items of $125 million ($0.35 per share) for the third quarter of 1999. Sales for the third quarter of 2000 increased to $3.8 billion from $2.1 billion in 1999. In announcing the results, Dr. Ray R. Irani, chairman and chief executive officer, emphasized Occidental's commitment to debt reduction. "When we announced our intention to purchase Altura Energy, we made a commitment to reduce our total debt by $2 billion by the end of this year from the $9 billion pro-forma level reached in April of this year as a result of purchasing Altura. The reduction is being made through a combination of asset sales and cash flow", he said. "Thanks to strong oil and gas prices and production from the Altura properties, we have reached that goal three months ahead of schedule. The total debt at the end of the third quarter of $7.06 billion includes $2.08 billion of the Altura non-recourse debt. The ratio of debt to total capitalization, which rose with the Altura financing, has declined dramatically and is now essentially unchanged from the beginning of the year. Debt reduction remains our highest priority and we will continue to use our strong cash flow and the proceeds from asset sales to achieve additional reductions in the fourth quarter." Results for the quarter included after-tax gains of $39 million from the partial-interest sale of the subsidiary that owned Occidental's Gulf of Mexico shelf assets; after-tax income of $41 million from the receipt of contingency payments related to a prior year sale of an oil and gas subsidiary in the Dutch North Sea; and a $1 million extraordinary gain resulting from the early extinguishment of debt. The results also included $49 million of after-tax charges related to the write-down of various oil and gas assets, real estate and investments. Oil and Gas ----------- The oil and gas division earned $690 million before special items, compared with $279 million for the third quarter of 1999. The improvement is primarily the result of higher worldwide crude oil and natural gas prices combined with increased domestic oil production volumes. The net increase in domestic production volumes, resulting from the acquisitions of Altura and THUMS in the second quarter of 2000, more than offsets lower international production. The overall earnings improvement was partially offset by higher exploration expense. Oil and gas earnings after special items were $696 million for the third quarter of 2000, compared with $280 million for the third quarter of 1999. The 2000 results included $80 million of net gains from the previously described asset sale and the receipt of contingency payments, partially offset by charges of $74 million, on a pre-tax basis, to write down various oil and gas assets, real estate and investments.

Chemicals --------- The chemical division earned $47 million for the third quarter of 2000, compared with $44 million for the third quarter of 1999. Since the second quarter of 2000, chemical earnings have declined primarily due to reduced sales prices and volumes in EDC and PVC and higher energy and feedstock costs. For the first nine months of 2000, Occidental's net income was $1.2 billion ($3.36 per share), compared with $65 million ($0.17 per share) for the first nine months of 1999. Net income for the nine months before special items was $977 million ($2.65 per share), compared with net income of $61 million ($0.15 per share) for 1999. Sales increased from $5.1 billion in the nine months of 1999 to $9.4 billion for the same period of 2000. -0- Contacts: Howard Collins (media) 310-443-6523 Kenneth J.

Item 9. Regulation FD Disclosure - ------- ------------------------ Text of Speech by Stephen I. Chazen, Executive Vice President - Corporate ------------------------------------------------------------------------- Development and Chief Financial Officer --------------------------------------- Occidental Petroleum Corporation STEPHEN CHAZEN Chief Financial Officer and Executive Vice President - Corporate Development - Conference Call - Third Quarter 2000 Earnings Announcement October 18 Los Angeles, California Good morning everyone, and thank you for joining us. EARNINGS -------- The continuing strength of oil and natural gas prices, together with a full quarter of production from our Permian properties in Texas and the THUMS properties in Long Beach, have resulted in another very strong quarter. Third quarter net income is $402 million, or $1.09 per share. This represents more than a three-fold increase above the $126 million, or $0.35 per share, we reported in the third quarter of 1999. Income before special items was $370 million, or $1.00 per share, compared to income before special items of $125 million, or $0.35 per share, in the third quarter of 1999. Our third quarter 2000 results include after-tax gains totaling $80 million. These gains include $41 million in payments related to the 1998 sale of oil and gas assets in the Dutch North Sea and an after-tax gain of $39 million from sale of oil and gas interests on the continental shelf in the Gulf of Mexico. The quarterly results also included $49 million of after-tax charges to write-down various oil and gas assets and investments and a $1 million gain from early retirement of debt. Oil and gas divisional earnings after special items were $696 million for the quarter. This is an increase of $416 million over the same quarter last year and $139 million over the second quarter of this year. Before special items oil and gas earnings were $690 million for this quarter. Chemical divisional earnings before special items were $47 million for the quarter. This is a decrease of $107 million over the second quarter of this year. Through the first nine months of this year, our net income rose to over $1.2 billion, or $3.36 per share. Our net income before special items for the first nine months of 2000 was $997 million, or $2.65 per share. 6

DEBT ---- Turning to the balance sheet, when we acquired Altura in April of this year, on a pro-forma basis we increased Oxy's debt from $5.4 billion at year-end 1999 to $9.0 billion. At that time we committed to reduce total debt to $7 billion by the end of this year. The $2 billion debt reduction target was to consist of $1.2 billion from asset sales and $800 million from cash flow. At the end of the third quarter, Oxy's total debt is about $60 million over the $7 billion targeted debt level. This is three months ahead of our scheduled commitment. Of the $2 billion debt reduction, approximately $1 billion is from asset sales and approximately $1 billion is from cash flow. In addition, Oxy's third quarter balance sheet will reflect invested cash of $200 million - so net debt is actually about $6.85 billion. To reflect our fourth quarter intentions for this cash we have characterized $200 million of debt as current maturities to be paid off in the quarter. Included in the $7 billion of total debt at the end of the third quarter is the Altura non-recourse debt. We committed to reduce this non-recourse debt from $2.4 billion to $2.1 billion by the end of this year. At the end of the third quarter the Altura non-recourse debt was $2.08 billion for a reduction of $320 million. We expect the Altura non-recourse debt to be below $2.0 billion by the end of this year. The total debt of $7 billion at the end of the third quarter of this year represents a ratio of 60 percent total debt to total capitalization. This is the essentially same ratio that we had at the start of the year when debt was $5.4 billion and before the $3.6 billion Altura acquisition. While we have reached our targeted debt level three months ahead of schedule we will continue to make debt reduction the highest priority. We will use our cash flow and any proceeds from asset sales to achieve additional reductions in the fourth quarter. With this lower debt level we expect to see interest expense decline in the fourth quarter of this year compared to the third quarter. Now I would like to turn the conference call over to Dale Laurance, president of Occidental. Text of Speech by Dr. Dale R. Laurance, President ------------------------------------------------- Occidental Petroleum Corporation Dr. Dale R. Laurance President - Conference Call - Third Quarter 2000 Earnings Announcement October 18, 2000 Los Angeles, California Thank you, Steve. I will focus my remarks on the key operating results that are driving this strong financial performance. 7

OIL AND GAS ----------- Domestic liquids production for the third quarter of this year was 210 MB/D compared to 71 MB/D in the third quarter of last year. International production in the third quarter of this year was 166 MB/D compared to 223 MB/D last year. The decline is primarily attributable to the sale of our producing properties in Peru last December. Domestic gas production was 687 MMCF/D in this year's third quarter compared to 673 MMCF/D last year. Permian gas production increased over 100 MMCF/D this year compared to last year due to the Altura acquisition. The decline in US Other gas production this year is due to the sale of the Gulf of Mexico properties in the third quarter of this year. BOE production from Altura this year has averaged 143,000 per day, about 8,000 BOE/D greater that we originally projected. Overall, Occidental's BOE production in the third quarter increased 20 percent over last year's third quarter. As expected, oil realizations are considerably greater than last year. What is important is that Oxy's net oil price realizations as a percent of WTI have significantly improved. Our asset restructuring has included selling properties with lower net price realizations and adding properties with higher net price realizations. Now our domestic oil realization is about 90 percent of WTI price compared to 80 percent of WTI in last year's third quarter. In Other Western Hemisphere the realization improvement is more dramatic. As a result of the sale of our producing asset in Peru last year our realizations in Other Western Hemisphere increased from 72 percent of WTI to 83 percent of WTI. The higher realizations together with the operating cost reductions mean that Oxy's profitability per BOE has improved significantly. Natural gas prices also improved in the third quarter of this year - compared not only to the third quarter of last year, but also to the second quarter of this year. United States natural gas price realizations as a percentage of the average NYMEX price increased significantly. The third quarter natural gas price realization was 99 percent of NYMEX compared to 90 percent for the same period last year. At Elk Hills, gas prices were substantially higher in September than the MERC price because of shortages in California caused by the explosion of the El Paso gas pipeline. Hence, due to the unique California gas market, we would expect our domestic natural gas realizations in the fourth quarter to be higher than the third quarter. Exploration expense for the third quarter of this year was $44 million compared to $11 million for last year's third quarter. CHEMICALS --------- As Steve noted, chemical earnings before special items declined this quarter compared to the second quarter. The primary reasons are lower sales prices and volumes in chlorine and PVC, together with higher energy and feedstock costs and lower ethylene dichloride earnings. 8

The reduction in demand for chlorine from the vinyls segment affected plant-operating rates. The current chlor-alkali operating rates are 86 percent compared to 99 percent in the first half of this year. While this is a negative factor for chlorine, it is a positive factor for caustic soda. Stable product demand has resulted in product shortages and supported two price increase totaling $110/ ton. Due to price protection provisions in our caustic soda contracts, we will not see the benefit of these price increases until the fourth quarter of this year and the first quarter of 2001. However, we expect the net benefit of the caustic soda price increases will be largely offset by lower chlorine prices. The reduced PVC prices and operating rates are the result of the slow-down in the economy due to the increase in interest rates by the Fed and to inventory de-stocking. During the first half of the year PVC demand was driven by a favorable economy, fears of product shortages and rising prices that encouraged an inventory build-up. Beginning in June, rising interest rates finally slowed down the demand. In August, industry-operating rates fell below 80 percent as inventories were worked down. Customer orders are now for demand only. The current fourth quarter outlook for PVC demand shows little improvement over the third quarter. I will close our formal remarks by reiterating that debt reduction remains our top priority, and we expect to achieve substantial reductions in our debt levels in the fourth quarter and throughout next year. 9

Year-to-date prices have improved $77/ton over 1999. o For the quarter, OxyChem average external net prices improved $11/ton over 2nd quarter 2000. Industry Commentary (CMAI) - ------------------- o Reduced demand into the vinyls industry introduced additional product into the spot market. Spot prices dropped during the quarter while contract prices to the vinyls industry remained largely unchanged. Downward pressure is expected to continue in the 4th quarter. o Although some price reductions are forecast for the 4th quarter and 1st quarter 2001, very little new chlorine capacity will be brought online during the next 12 months. Therefore, chlorine prices should remain at fairly high levels on average. 20

Investor Relations Supplemental Schedules [OXY LOGO] o U.S. chlorine demand is expected to reflect 2.4% growth for 2000. Consumption into the vinyls sector is forecast to pick up starting in the 2nd quarter, 2001. Influencing Factors - ------------------- Demand into the vinyls sector is temporarily weakened. With limited available production capacity, returning demand will drive long-term volume and upward price pressures. CAUSTIC - ------- OxyChem Commentary - ------------------- o OxyChem's 3rd quarter net average domestic prices declined $6/ton as contract buyers received the remaining benefit of price weakness earlier in the year. Announced price increases of $50/ton for July and $60/ton for August will significantly improve 4th quarter and future realized net values. o Inventories declined through the 3rd quarter and are down significantly for the year. Short supplies will continue through the remainder of the year. o Demand continues to demonstrate strength and stability. Industry Commentary (CMAI) - ------------------- o Spot prices reached a level of $200/DST with some buyers paying "well above" that amount for urgently needed product. While contract pricing is forecast to increase during the 4th quarter, there appears to be additional room for future price increases. o U.S. demand rose 8.5%, in the 1st half 2000 compared to 1st half 1999. With operating rates reduced during the 2nd half, 3% production growth is forecast for the year. Influencing Factors - ------------------- Lower operating rates will continue to limit supply and allow price improvements. Demand remains strong. EDC - --- OxyChem Commentary - ------------------ o Continued weakness into the PVC/VCM markets and expectations of ethylene price declines are providing downward price pressure. Price weakness is expected to continue through the 4th quarter. Industry Commentary (CMAI) - ------------------- o Export prices declined further to 11.0-11.5(cent)/lb (FOB) for September shipments. 21

Investor Relations Supplemental Schedules [OXY LOGO] o Demand remains weak with indications that inventories in Asia remain high. Influencing Factors - ------------------- Declining demand in vinyls has softened pricing from all-time 2nd quarter highs. PVC/VCM OXYCHEM INDUSTRY (CHEM DATA) - -------- ------- -------- Operating Rates (U.S.) 87% 85% OxyChem Commentary - ------------------ o Domestic PVC prices decreased 3.5(cent)/lb since May, remaining up 1.5(cent)/lb in 2000. o Domestic demand weakness continued through the quarter with continued inventory adjustments and an overall slow-down in the construction industry. o Export volume began increasing in June with Shintech moving product from the U.S. to sell out their new plant. Export volume increased again in August as U.S. producers moved additional inventory into the market. o Asian export prices held during the third quarter at $670-680/MT CFR, but face downward pressure as material from the U.S., Middle East, and Europe tries to find a home in China. Latin America prices have steadily declined since June and continue to face downward pressure with capacity additions at Shintech and Petco. Current prices are $585-650 CFR. o Domestic VCM prices were 27(cent)/lb for July, 26(cent)/lb in August, and are expected to settle at 25.5(cent)/lb for September. These decreases are attributable to lower PVC and ethylene prices. o For October shipments, the export VCM price decreased to $430-440/MT F.O.B. U.S. Gulf Coast. Industry Commentary (CMAI) - ------------------- o PVC price remains under downward pressure due to weak demand in all regions. o VCM demand has weakened for both domestic and export shipments. Influencing Factors - ------------------- Product prices remain under downward pressure from weak demand in all regions. Long term, capacity limitations and demand strength will continue benefit product prices and volumes. 22

At that time we committed to reduce total debt to $7 billion by the end of this year. The $2 billion debt reduction target was to consist of $1.2 billion from asset sales and $800 million from cash flow. At the end of the third quarter, Oxy's total debt is about $60 million over the $7 billion targeted debt level. This is three months ahead of our scheduled commitment. Of the $2 billion debt reduction since April, approximately $1 billion is from asset sales and approximately $1 billion is from cash flow. In addition, Oxy's third quarter balance sheet will reflect invested cash of $200 million--so net debt is actually about $6.85 billion. To reflect our fourth quarter intentions for this cash we have characterized $200 million of debt as current maturities to be paid off in the quarter. The total debt of $7 billion at the end of the third quarter of this year represents a ratio of 60 percent total debt to total capitalization. This is the essentially the same ratio that we had at the start of the year when debt was $5.4 billion and before the $3.6 billion Altura acquisition. While we have reached our targeted debt level three months ahead of schedule we will continue to make debt reduction the highest priority. We will use our cash flow and any proceeds from asset sales to achieve additional reductions in the fourth quarter. With this lower debt level we expect to see interest expense decline in the fourth quarter of this year compared to the third quarter. 24
