Item 5. Other Events - ------ ------------ On November 18, 1999, Occidental Petroleum Corporation announced that its OXY USA Inc. subsidiary has agreed to resolve its long-standing Oklahoma litigation with Chevron U.S.A. Inc. (a subsidiary of Chevron Corporation) for a cash payment of $775 million from Chevron U.S.A. Occidental intends to use the proceeds from the settlement primarily to pay down its debt. This litigation arose from the 1982 termination by Gulf Oil Corp. (which was subsequently acquired by Chevron) of its merger agreement with Oklahoma-based Cities Service Company (which was subsequently acquired by Occidental). In 1996, a judgment in favor of OXY USA (formerly Cities Service) was entered against Chevron U.S.A. by a state district court in Tulsa, Oklahoma. The Oklahoma Supreme Court affirmed the trial court judgment earlier this year. Shortly thereafter, Chevron filed a petition to the U.S. Supreme Court to review the judgment. That petition has been withdrawn under the terms of the agreement with Chevron U.S.A.
