To Our Shareholders: Pacific Century Financial Corporation's continued steady earnings performance assures us that we are on course with our strategy of growth and diversification. Your company posted second-quarter earnings of $35.6 million, up 2.9 percent from the same period last year. Earnings per share for the second quarter were $0.89 compared to $0.84 for the second quarter of 1996, an increase of 6.0 percent. Year-to-date return on average assets was 1.04 percent and return on average equity was 13.37 percent. Earnings for the first six months of 1997 were $71.1 million, compared to $67.3 million for the first half of 1996, a 5.6 percent increase. Year-to-date earnings per share of $1.77 were 8.6 percent higher than the $1.63 reported for the first half of 1996. Pacific Century's total assets at the end of June 1997 were $14.2 billion, an increase of 3.5 percent from $13.7 billion at June 30, 1996. Deposits and repurchase agreements ended the quarter at $11.1 billion, up from $10.1 billion on the same date a year earlier. Pacific Century achieved growth in loans of 5.4 percent above last year's second-quarter level and 3.0 percent above the first-quarter 1997 level. Net loans at June 30, 1997 were $8.7 billion, an encouraging figure given the state's lackluster economy. At quarter-end, non-performing assets (NPAs) excluding loans 90-plus days past due totaled $93.6 million or 1.04 percent of total loans. This compares to $84.0 million or 0.98 percent of total loans on the same date last year. We are pleased to welcome Stephen G. Carpenter, CEO, David I. Rainer, president, and the rest of the management and staff of California United Bank to the Pacific Century family. On June 27, shareholders of CU Bancorp voted overwhelmingly to approve the merger with Pacific Century Financial Corporation. The acquisition was completed on July 3, 1997, and approximately 2.3 million shares of Pacific Century Financial Corporation common stock have been issued to CU Bancorp shareholders in conjunction with the merger. Pacific Century's board of directors authorized the discretionary repurchase of a similar number of shares of its common stock in open market transactions. California United Bank (CUB) provides a platform from which we will leverage our already-strong presence in Asia and throughout the Pacific region. CUB is an excellent match for us in terms of its service orientation and market focus, and the synergy that develops between CUB and Pacific Century's other subsidiaries, principally Bank of Hawaii, will benefit shareholders and customers alike. CUB, based in Encino, California, has assets of approximately $800 million and serves primarily middle market businesses and consumers in the greater Los Angeles area. Pacific Century Financial Corporation continues to look for opportunities to diversify and grow through acquisition. On June 19, Bank of Hawaii signed a non-binding letter of intent to acquire the interest of Paribas Group in Banque Paribas Pacifique and Banque Paribas Polynesie, located respectively in New Caledonia and French Polynesia. The bank also announced plans to expand its service delivery network in Hawaii by providing Bankoh BankMachine ATM services at 47 7-Eleven store locations throughout the state. Bank of Hawaii is proud to be the first bank in Hawaii to bring Internet banking to market. During the second quarter, Bankoh announced that it will begin offering secure Internet banking to customers this Fall and launched a demonstration site of its virtual bank, known as e-bankoh, on the Net at <www.boh.com>. The addition of e-bankoh will complement the company's extensive branch and ATM network, making our delivery channel system unparalleled in the Pacific. In June, Eduardo A 'Champ' Calvo, managing partner of the law firm of Calvo and Clark, was named to the board of directors of Bank of Hawaii. As a resident of Guam, his perspective will add diversity to our board and strengthen the management of our franchise. At its meeting on July 25th, your board declared a quarterly dividend of 32 1/2 cents per share on the outstanding common stock, an increase of 8.3 percent from the previous rate of 30 cents per share. Pacific Century last increased its dividend in July 1996 when the board approved a 2 cent per share increase. The dividend will be payable on September 16, 1997 to shareholders of record at the close of business on August 22, 1997. Your company's performance continues to reflect its management's long-term approach to growth, diversification and development of its pan-Pacific franchise. We value your support and continually seek to enrich the value of your investment in Pacific Century Financial Corporation. Sincerely, LAWRENCE M. JOHNSON Lawrence M.
