Exhibit 99.1 FOR IMMEDIATE RELEASE CONTACTS: BNP Paribas: Michele Sicard 33 1 40 14 70 61 Agathe Heinrich 33 1 42 98 15 91 Henri de Clisson 33 1 40 14 65 14 BancWest Corporation: Gerry Keir (808) 525-7086 cell (808) 282-2768 BNP PARIBAS COMPLETES ACQUISITION OF BANCWEST BancWest Corporation Becomes Wholly-Owned Subsidiary of BNP Paribas; First Hawaiian Bank, Bank of the West Remain Separate Banks (Paris, France and Honolulu, Hawaii, December 20, 2001) -- BNP Paribas and BancWest Corporation announced today that they have closed the transaction in which BNP Paribas acquired the 55% of BancWest stock it did not already own. The transaction was structured as a merger of BancWest with a subsidiary of BNP Paribas. BancWest is now a wholly owned subsidiary of BNP Paribas. BancWest stock, which had been listed on the New York Stock Exchange (Symbol: BWE), will no longer be publicly traded. Completion of the transaction means that all outstanding BancWest shares (except those owned by BNP Paribas) have been converted into the right to receive a $35-per-share cash payment. BancWest will also pay a pro rata dividend of $0.0396 per share, with a record date of December 19 and payment date of December 28. BancWest remains headquartered in Honolulu, under existing management. Its major subsidiaries -- Bank of the West (San Francisco) and First Hawaiian Bank (Honolulu) -- will continue to operate as separate institutions using their present names. Michel Pebereau, Chairman and CEO of BNP Paribas, said: "We are delighted to have achieved this merger agreement. Through our relationship with BancWest, we have a great deal of confidence in its people. Not only is this transaction immediately accretive, allowing the Group and its shareholders to fully benefit from BancWest's expanding earnings, but the BancWest platform, with 1.1 million customers in markets offering high long-term growth potential, will allow us to leverage our broad financial services expertise." "This change rewards our stockholders for their support ofBancWest and positions our company, under its new ownership, for dramatic growth in the Western United States," said Walter A. Dods, Jr., Chairman and Chief Executive Officer of BancWest. "For our customers in Hawaii and the West, however, it's business as usual at our branches. Both First Hawaiian and Bank of the West will remain community banks, with an emphasis on decentralized, personal service." BancWest stockholders who have stock certificates in their possession will receive instructions by mail from Mellon Investor Services LLC, the paying agent, concerning how and where to forward their certificates for payment. BancWest stockholders should exchange their stock certificates for the merger consideration

promptly following receipt of these materials. It is not possible to defer recognition of income for tax purposes by delaying the exchange of stock certificates. Brokers will handle conversion for those holding BancWest stock in a brokerage account. The merger does not affect preferred securities or capital securities issued by BancWest Capital I or First Hawaiian Capital I. On December 10, BNP Paribas and BancWest Corporation announced plans to further expand operations in the west with BNP Paribas' acquisition of United California Bank from its parent company, UFJ Holdings of Japan. Next year, United California Bank branches will become part of Bank of the West, a BancWest subsidiary, more than doubling Bank of the West's California presence. The United California Bank acquisition will solidify BancWest's position as one of the premier western financial services franchises. Following the acquisition, BancWest will have $31 billion in assets and serve 1.5 million customers from more than 350 branches in California, Hawaii, five other Western states, Guam and Saipan. Bank of the West will have $15 billion in deposits within California, ranking fourth in bank deposit market share in the nation's most populous state. This $2.4-billion cash transaction is expected to close by the end of the first quarter of 2002, subject to regulatory and other approvals. United California Bank will then be merged into Bank of the West by the end of the third quarter of 2002, and the consolidated company will operate under the Bank of the West name.
