BANCWEST POSTS EARNINGS OF $113.1 MILLION,
UP 10.7% FROM FIRST QUARTER OF 2003
Community First Acquisition Announced During Quarter

     (Honolulu, Hawaii, April 14, 2004) – BancWest Corporation, parent company of Bank of the West and First Hawaiian Bank, today reported net income of $113.1 million for the first quarter of 2004, up 10.7% from the same quarter of 2003.

     “BancWest continues to generate organic growth at a double-digit percentage rate and we reduced our ratio of nonperforming assets for the sixth consecutive quarter,” said Walter A. Dods, Jr., BancWest Chairman and Chief Executive Officer. “During the quarter, we also furthered our strategy of regional expansion by agreeing to acquire Community First Bankshares, a transaction that makes sense both strategically and financially.”

     On March 16, BancWest announced a definitive agreement to acquire Community First Bankshares, Inc. (Nasdaq: CFBX). Community First Bankshares is the parent company of Community First National Bank, which operates 155 branches in 12 states in the Southwest, Rocky Mountains, Great Plains and east to Minnesota, Iowa and Wisconsin.

     “Our pending acquisition of Community First Bankshares will make BancWest the seventh largest bank holding company in the Western United States,” said Don J. McGrath, President and Chief Operating Officer of BancWest and President and Chief Executive Officer of Bank of the West. “Community First operates in growing states that complement Bank of the West’s existing footprint.”

BancWest first-quarter results:

     Assets, loans, deposits. BancWest had total assets of $38.9 billion at March 31, 2004, up 11.5% from a year earlier. Loans and leases totaled $26.2 billion, up 9.0%. Deposits were $26.7 billion, up 9.9%.

     Credit quality. BancWest’s nonperforming assets were 0.58% of loans and foreclosed properties at March 31, 2004, an improvement from 0.98% at March 31, 2003 and 0.59% at December 31, 2003.

     Loan loss reserve. BancWest’s allowance for credit losses was 1.51% of total loans and leases at March 31, 2004, compared to 1.65% at March 31, 2003 and 1.52% at December 31, 2003.

     Net interest income for the quarter was $321.0 million — up 1.8% from the first quarter of 2003, due to 13.8% growth in average earning assets, partially offset by a lower net interest margin for the quarter. Net interest margin was down to 3.98% compared with 4.49% for the same quarter a year ago.

     Noninterest income, at $101.4 million, increased 7.0% from the first quarter of 2003.

     Noninterest expense was $218.9 million for the quarter, down 0.8% from the same quarter a year ago.

Community First acquisition

     In the transaction announced last month, BancWest agreed to pay $32.25 in cash for each Community First share, a total of $1.2 billion. As of December 31, 2003, Community First Bankshares had total assets of $5.5 billion, deposits of $4.4 billion and loans of $3.3 billion. In 2003, the company earned $75 million.

     The merger requires approval from Community First shareholders and federal and state banking regulators. Once all regulatory approvals have been received, the merger is expected to close during the third quarter of 2004. Subsequently, Community First branches will become part of Bank of the West, adding 10 new states to Bank of the West’s footprint. Following the acquisition, BancWest will have $44 billion in assets and serve 3.4 million accounts through more than 510 branches in 17 states, Guam and Saipan.
