Item 5. Other Events - ------ ------------ Second Quarter Earnings - ----------------------- Occidental Petroleum Corporation announced on July 19, 2000 that its second quarter 2000 net income of $564 million ($1.53 per share) marks the best quarter in the company's history. These results included an after-tax gain of approximately $300 million related to the previously announced sale of Occidental's 29.2 percent interest in Canadian Occidental Petroleum Ltd. (CanOxy) and an after-tax charge of approximately $80 million for the previously announced decision to exit several of Occidental's chemical intermediate businesses. The 2000 second quarter net income compares to $9 million ($.02 per share) of net income reported for the second quarter of 1999. Earnings before special items were $343 million for the second quarter of 2000, compared with earnings before special items of $4 million for the second quarter of 1999. Sales of $3.1 billion for the second quarter of 2000 were nearly double the $1.6 billion reported for the same period in 1999. Oil and Gas ----------- Oil and gas divisional earnings were $557 million for the second quarter of 2000, compared with $166 million for the second quarter of 1999. The significant improvement in earnings is primarily the result of higher worldwide crude oil and natural gas prices and higher production volumes. The increase in domestic production volumes, resulting from the completed acquisitions of Altura Energy Ltd. and ARCO Long Beach Inc., (THUMS) more than offset the lower international production resulting from the sale of our producing assets in Peru. Chemicals --------- Chemical divisional results before special items were $154 million for the second quarter of 2000, compared with $21 million for the second quarter of 1999. The improvement in earnings is due to higher margins and sales volumes for Polyvinyl Chloride resins, Ethylene Dichloride, Vinyl Chloride Monomer and Chlorine. Partially offsetting these increases were higher energy and feedstock costs. Chemical results after special items for the second quarter of 2000 were $34 million compared with $33 million for the second quarter of 1999. The 2000 results include a $120 million pre-tax charge resulting from the decision to exit several of its chemical intermediate businesses. The 1999 results included a $12 million gain from the sale of a plant by an equity affiliate.

Other ----- The second quarter of 2000 included a $493 million pre-tax gain related to the sale of Occidental's investment in CanOxy. For the first six months of 2000, Occidental's net income was $835 million ($2.27 per share), compared with a net loss of $61 million ($.20 per share) for the first six months of 1999. The six months results before special items were net income of $607 million for 2000, compared with a loss before special items of $64 million for 1999. Sales were $5.6 billion for the six months of 2000, compared with $3.0 billion for the same period of 1999. 2

Item 5. Other Events (Continued) - ------ ------------------------ Recent Development - Monetization of Gulf of Mexico Assets - ---------------------------------------------------------- Occidental Petroleum Corporation announced on July 20, 2000, that it has agreed to two transactions with Apache Corporation involving Occidental's interests in proved reserves of about 50 million barrels of oil equivalent in the Continental Shelf of the Gulf of Mexico. These transactions will generate proceeds of $341 million this year and and are expected to generate additional proceeds of $11 million per year for the next four years -- for a total consideration of $385 million. In one transaction, Occidental agreed to sell its share of gas production of a wholly owned subsidiary holding its Gulf of Mexico shelf assets for approximately $280 million. In a separate transaction, Occidental also agreed to sell an interest in that subsidiary for approximately $61 million, with an option to purchase additional interests for $44 million. As a result of these two transactions, which are expected to close August 15, Occidental will record a pretax gain of approximately $65 million.
