Other Events Gulf Region USA Restructuring ------------------------------ The Company's Gulf Region business unit commenced a restructuring program to improve its overall cost structure and profitability and better position the unit for ongoing exploratory success. The actions taken so far under the restructuring program are expected to reduce pre-tax costs by approximately $20 million per year by making organizational changes to eliminate unnecessary work processes and reconfiguring the business unit to meet current and future business needs. The restructuring measures involve about 200 layoffs from the Gulf Region workforce in the Company's Sugar Land, Texas, office and field locations. The cuts represent about 7 percent of the Company's total U.S. workforce. The focus of the exploration program has been redirected from the Gulf of Mexico's mature shallow depths to the emerging "deep shelf" play. The restructuring also will involve the divestment of low margin properties by the end of 2002. The divestments will allow the Gulf Region unit to concentrate its efforts on more profitable fields and potentially high impact exploration prospects. The impact of the asset sales on production and reserves is expected to be minimal. The Company expects to record an after-tax charge of approximately $12 million for the layoff part of the restructuring program in the second quarter of 2002. Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned, thereunto duly authorized.
