To Our Shareholders:

We are pleased to report that Pacific Century Financial
Corporation's first quarter 2000 earnings were among the
strongest in your company's history.  For the first three months
of this year, earnings reached $39.8 million, up 12.3 percent
from $35.4 million reported for the same period last year.
Diluted earnings per share were 50 cents, up 13.6 percent from 44
cents reported for 1999's first quarter.

         Tangible earnings for the quarter were $43.9 million
compared to $39.3 million reported for the same period last year.
Tangible diluted earnings per share for the quarter were 55
cents, up 14.6 percent from 48 cents reported for the first
quarter of 1999.

         Return on average assets for the quarter was 1.13 percent
compared to 0.96 percent for 1999's first quarter.  Return on
average equity was 13.19 percent versus 12.00 percent for the
same period last year.

         The first quarter's improved performance reflects your
company's steady progress in implementing its New Era Redesign
initiatives.

         Pacific Century saw improvement in non-interest expense in
the first quarter, which stood at $126.1 million, down 6.5
percent from the first quarter of 1999. Factors contributing to
the improvement in expenses include the implementation of New Era
initiatives and the reduction in costs related to Y2K readiness.

         We are encouraged to note that Hawaii's economy continues to
gain momentum, causing economists to revise growth forecasts for
2000 upward, with consensus forecasts for real GSP growth this
year between 2.5 and 3.0 percent.  Continued strength in U.S.
mainland tourism, stabilization in Asian tourism, and increased
construction and investment activity are among the factors
contributing to the economic expansion.

         Bank of Hawaii recently made headlines when we introduced
cutting-edge automated banking technology and service
enhancements at our relocated Waikiki Branch--some of which will
also be incorporated into other Hawaii branches. Clients can
conduct their banking via "virtual" tellers, online and telephone
banking kiosks, and a BankLanai featuring advanced-function ATMs
and bank machines for businesses.  In addition, the branch offers
personalized services through personal and business bankers, Asia
Division personnel and a BranchConcierge. Bank of Hawaii also
recently launched e-Bankoh for Business, an Internet banking
service designed for small businesses.

         At your company's annual meeting in April, you and your
fellow shareholders voted to approve all of the proposals listed
in this year's proxy statement:  the re-election of four
directors to the holding company board, David A. Heenan, Stuart
T.K. Ho, Lawrence M. Johnson, and Fred E. Trotter, and the re-
election of Ernst & Young LLP as independent auditor.

         At its April 28th meeting, your board of directors declared
a quarterly cash dividend of 18 cents per share on the
outstanding common stock--an increase of 5.9% over last quarter's
dividend.  The dividend will be payable on June 14, 2000 to
shareholders of record at the close of business on May 26, 2000.

         We remain confident in the strength of your company and its
ability to build upon the positive momentum reflected in the
first quarter earnings. We appreciate your continuing support as
we move forward in our New Era and in the new millennium.

Sincerely,

/s/ LARRY JOHNSON
