PGS Sells Subsidiary

Petroleum Geo-Services ASA and China National Chemicals Import & Export Corporation ("Sinochem") have signed a definitive agreement for the sale of PGS' Atlantis subsidiary. The closing of the transaction, which is expected to occur in the first quarter of 2002, is subject to certain conditions including receipt of consents and waivers from governmental authorities. Under the terms of the definitive agreement, the total proceeds of the sale, including assumption of debt, are expected to be approximately $215 million. The transaction will be effective from Jan. 1, 2001, and therefore the exact sales proceeds will depend on the actual amount of qualified capital expenditures made by PGS on behalf of Atlantis between Jan. 1, 2001, and the final closing date of this transaction. Chairman and Chief Executive Officer of Petroleum Geo-Services, Reidar Michaelsen, said, "While the complexity of the Atlantis portfolio caused some unexpected delays in the completion of this transaction, we are very happy to have reached a definitive agreement with Sinochem for the sale of these assets. We have great respect for Sinochem and their negotiations team. We believe they will benefit greatly from the assets that Atlantis has only begun to develop." Sinochem Chief Executive Officer, Liu Deshu, said, "We are very pleased with this significant acquisition. Throughout this process we have been impressed with the Atlantis management team, their expertise and vision. We are also grateful to PGS and their advisors who helped facilitate this transaction." Liu Deshu further added, "The acquisition of Atlantis is a major step in our strategy to expand into the global upstream sector. It is also consistent with our goal of improving the competitiveness of Sinochem's overall petroleum operations through vertical integration. We look forward to making Atlantis an integral part of our oil and gas business, as well as further cooperation with large Chinese and foreign partners.” Michaelsen went on to say, "The sale of Atlantis will complete our program to sell non-core assets that we communicated a little over one year ago. During this period and including the expected proceeds from the sale of Atlantis, PGS will have realized more than $500 million from sales of non-core assets. Additionally, during the past year, PGS has reorganized its geophysical business, addressed certain issues relating to the Banff FPSO, refurbished and re-deployed the Petrojarl I FPSO on a new contract, secured additional work for the Varg FPSO and entered into a definitive agreement for a strategic business combination with Veritas. The sale of Atlantis will also satisfy one of the conditions to closing of the Veritas transaction. While it has been a very active and challenging period for our management team, we are very excited about the future opportunities and look forward to completing the Veritas transaction." JP Morgan acted as financial advisor to PGS on this transaction. Watson, Farley & Williams acted as PGS' legal advisors. ABN AMRO acted as financial advisor to Sinochem and Coudert Brothers acted as its legal advisors.
