Common Stock
Par Value $.01 per Share
Dividend Reinvestment and Stock Purchase Plan

    This prospectus describes Pacific Century Financial Corporation's Dividend Reinvestment and Stock Purchase Plan, as amended. The Plan provides holders of shares of Pacific Century common stock, employees, retired employees and directors of Pacific Century and its subsidiaries, Hawaii residents and certain members of the Bank of Hawaii Profit Sharing Plan with a simple, cost effective and convenient method of investing in our common stock.

    The Plan allows you to:

    We pay all commissions and service charges for reinvesting dividends and purchasing additional shares of common stock through optional cash purchases. There are, however, commissions and service charges for using other Plan services, including if you sell shares from the Plan.

    If you currently are participating in the Plan, you will remain enrolled in the Plan and you do not have to do anything unless you want to end your participation, change your elections or change your direct debit amounts for optional payments. If you are not a participant in the Plan but are eligible to join, you may become one by completing an authorization form or initial stock purchase form and returning it to Continental Stock Transfer & Trust Company, which administers the Plan. You may request those forms by calling 1-800-509-5586. Shareholders who do not wish to participate in the Plan and reinvest dividends will continue to receive cash dividends, as declared, in the usual manner.

    This prospectus covers 1,000,000 shares of our common stock that we recently reserved for issuance and registered for sale under the Plan. This prospectus also covers any remaining unissued shares out of the 3,100,000 shares of our common stock previously reserved for issuance and registered for sale under the Plan. You should keep this prospectus for future reference.

    Our common stock is listed and traded on the New York Stock Exchange under the symbol "BOH". On June 25, 2001, the closing price per share of our common stock on the NYSE was $24.77.

    Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

    These securities will be our equity securities and will not be savings accounts, deposits or other obligations of any bank or nonbank subsidiary of ours and are not insured by the Federal Deposit Insurance Corporation, the Bank Insurance Fund or any other governmental agency.


This prospectus is dated June 29, 2001.

Pacific Century Financial Corporation

    Pacific Century is a Delaware corporation and a bank holding company. We were incorporated in Hawaii in 1971. We changed our state of incorporation to Delaware in 1998.

    Through our banking subsidiaries, we provide a diverse range of banking financial services, primarily in Hawaii and also in the West Pacific and selected other markets. Additional subsidiaries are engaged in various businesses, including consumer finance, equipment leasing, insurance and insurance agency services, securities brokerage and investment services. Our principal banking subsidiary is Bank of Hawaii. We also own, among other things, First Savings and Loan Association of America.

    Pacific Century is a separate and distinct legal entity from our banking and other subsidiaries. Dividends received from our subsidiaries are our principal source of funds to pay dividends on our common stock and debt service on our debt. Various Federal and state statutes and regulations limit the amount that our banking and other subsidiaries may pay to us without regulatory approval.

    Our principal executive offices are located at 130 Merchant Street, Honolulu, Hawaii 96813, telephone (808) 537-8239.

Description of the Plan

    The following is a question and answer explanation of the provisions of the Plan, as in effect on the date of this prospectus. If you do not participate in the plan, you will continue to receive cash dividends, as declared, by check or direct deposit.

1.  What is the purpose of the Plan?

    The primary purpose of the Plan is to provide existing shareholders with a simple and convenient method of investing cash dividends and making optional payments to purchase additional shares of our common stock without paying any brokerage commissions or service charges. Certain members of the Bank of Hawaii Profit Sharing Plan also are eligible to make optional payments to purchase common stock under the Plan. The Plan also permits employees, former employees and directors of Pacific Century and its subsidiaries, and Hawaii residents to join the Plan without paying brokerage commissions by making their first purchase of common stock through the Plan.

    Because shares that you acquire under the Plan will be purchased directly from us, we will receive the purchase price for those shares and will use them for general corporate purposes.

2.  What are the advantages of the Plan?

    If you participate in the Plan, you may:

3.  What are some possible disadvantages of the Plan?

4.  What are some important dates to remember about the Plan?

5.  Who administers the Plan?

    Continental Stock Transfer & Trust Company administers the Plan for participants, keeps records, sends statements of account to participants, and performs other similar duties relating to the Plan. The administrator is not affiliated with Pacific Century.

6.  Who is eligible to participate in the Plan?

    All record holders of our common stock are eligible to participate in the Plan.

    The following also may join the Plan by making their initial purchase of common stock through the Plan, if they are not already a record holder of common stock, or a beneficial holder of common stock who already is participating in the Plan:

However, our Chairman of the Board may suspend the eligibility of Hawaii residents to participate in the initial stock purchase provisions of the Plan at any time. He might do so if, for example, we did not have enough shares of common stock then available to meet the requirements of existing Plan participants, or to comply with an applicable law or regulation.

    Finally, members of the Bank of Hawaii Profit Sharing Plan who have an interest in its Pacific Century Stock Fund are regarded for Plan purposes as being record holders of our common stock, so they are eligible to make optional payments under the Plan, even if they own no other shares of common stock.

7.  How do I join the Plan?

    If you already are the record owner of shares of our common stock, you may join the Plan by obtaining, completing and signing an authorization form and returning it to the administrator. If you already own shares of common stock, and your shares are held in a name other than yours (for example, in "street" name, or the name of a bank, custodian or other nominee), you must either first transfer record ownership of your shares into your own name, or your nominee must elect to participate on your behalf.

    If you are eligible to join the Plan by making an initial purchase under the Plan, you may join the Plan by obtaining, completing and signing an initial stock purchase form and returning it to the administrator.

3


    You may obtain blank authorization forms and initial stock purchase forms from, and send completed forms to: Continental Stock Transfer & Trust Company, 2 Broadway, 19th Floor, New York, NY 10004. You also may obtain authorization and initial stock purchase forms by calling the administrator at (800) 509-5586.

8.  When may I join the Plan?

    If you already are the record owner of shares of our common stock, you may join the Plan at any time. If we receive your authorization form at least ten business days before the record date for a particular dividend, we will begin reinvesting your dividends with that dividend. In the past, quarterly dividend record dates usually have occurred during the last week of February, May, August and November, and the corresponding dividend payment dates usually have occurred on the tenth business day of March, June, September and December.

    If you are eligible to join the Plan by making an initial purchase under the Plan, we must receive your payment and initial stock purchase form on or before the last business day of the preceding calendar month. Also, we will return payments for initial purchases that we receive more than thirty-five days before the applicable investment date. For details about the investment dates, see question 12, "When will shares of common stock be purchased?" Therefore, when you join the Plan by making an initial stock purchase, you generally should make sure that we receive your payment and initial stock purchase form between the tenth of the month and the last day of the month.

9.  What options are available to me when I join the Plan?

    You may elect the following investment options when you join the Plan:

If your authorization form or initial stock purchase form does not specify an investment option, we will return it to you for completion or request further written instructions.

    Any shares that you acquire through optional purchase will be automatically enrolled in the Plan, so dividends on those shares will be automatically reinvested.

    If you do not elect full dividend reinvestment, you may have us directly deposit your cash dividends into your checking or savings account by completing and returning a direct deposit authorization to the administrator.

    Members of the Bank of Hawaii Profit Sharing Plan who participate as to their interest in its Pacific Century Stock Fund are eligible only to make optional payments with regard to that interest.

    You may change your investment option at any time by signing a new authorization form and returning it to the administrator. However, if you change your option with respect to reinvestment of dividends, your new election will be effective for a particular dividend only if we receive it ten business days preceding the record date for that dividend.

10. Will I have to pay any fees or expenses for purchases under the Plan?

    For purchases, you will not have to pay any commissions because you will purchase your common stock directly from Pacific Century. We will pay all other fees and costs of administering the Plan, except that you will pay brokerage commissions and certain fees if you elect to have the administrator sell shares on your behalf. Those commissions and fees are described in question 24, "Can I receive cash instead of share certificates when I withdraw shares or terminate my participation?"

11. Where do you get the common stock that participants purchase under the Plan?

    Shares are purchased directly from us out of authorized but unissued shares of our common stock.

12. When will shares of common stock be purchased?

    All purchases of common stock under the Plan, whether through dividend reinvestment, initial stock purchase or optional payment, will be made once a month on the investment date. In months in which we pay a cash dividend, the investment date will be the same as the dividend payment date. In other months, the investment date will be the tenth business day of the month.

13. At what price will shares of common stock be purchased?

    The price will be the market price, which for Plan purposes we will determine by averaging the closing price of our common stock on the NYSE for the five trading days ending on the investment date. However, if for any reason there is no trading in common stock during any of those days, we will determine the market price based on whatever market quotations we deem appropriate. We will never sell you shares at less than their par value, which is $.01 per share.

14. How many shares of common stock will be purchased for me?

    This depends on the amount of your reinvested dividend, payment for initial stock purchase or optional payment, and the market price of our common stock. Your account will be credited with the number of shares, including fractions computed to four decimal places, equal to the total amounts to be invested, divided by the applicable purchase price per share.

15. How do I make an initial stock purchase?

    If you are an employee, retired employee or director of Pacific Century or one of its subsidiaries or a resident of the State of Hawaii, and you are not a record holder of common stock, or a beneficial holder of common stock who already is participating in the Plan, then you may join the Plan by making an initial purchase of common stock through the Plan. Your payment must be in the form of a check or money order for at least $250. In addition, the sum of your initial stock purchase payment and any subsequent optional payments in the same calendar quarter may not exceed $5,000. For this purpose, we deem the payment to have been made on the date it was invested. Please make your check or money order payable to "Continental Stock Transfer & Trust Company," and send it and your initial stock purchase form to the administrator at: Continental Stock Transfer & Trust Company, 2 Broadway, 19th Floor, New York, NY 10004.

16. When may I make an optional payment?

    Once you have joined the Plan, you may make optional payments in any month. The rules that determine when you may make optional payments are the same rules that determine when an eligible participant can make an initial stock purchase, as described in question 8, "When may I join the Plan?" In other words, the administrator must receive your optional payment and optional payment form on or before the last day of the preceding calendar month. Also, we will return optional payments that we

5


receive more than thirty-five days before the applicable investment date. For details about the investment dates, see question 12, "When will shares of common stock be purchased?" Therefore, when you make an optional payment, you generally should make sure that we receive your payment and optional payment form between the tenth of the month and the last day of the month.

17. How do I make an optional payment?

    The sum of your optional payments in any calendar quarter (and any initial stock purchase through the Plan made in the same calendar quarter) may not exceed $5,000. For this purpose, we deem the payment to have been made on the date it was invested. You may vary the amount of each optional payment within these limits. You are not obligated to make any optional payments.

    Your payment must be in the form of a check or money order, which must be for at least $25. Please make your check or money order payable to "Continental Stock Transfer & Trust Company." If you want to make optional payments on a regular basis by having them deducted monthly from your checking or savings account, please complete and return an authorization to charge your deposit account. You may obtain blank optional payment and monthly deduction forms from, and must send completed forms and optional payments to: Continental Stock Transfer & Trust Company, 2 Broadway, 19th Floor, New York, NY 10004. You also may obtain optional payment and monthly deduction forms by calling the administrator at (800) 509-5586.

18. What other rules apply to initial stock purchases and optional payments?

    We will not pay interest on your initial stock purchase or optional payments while we hold them pending investment in common stock. Your check must clear before your funds will be available for a purchase under the Plan. Checks drawn on foreign banks are subject to collection fees and exchange rates on the date of negotiation. If you have sent in an initial stock purchase or optional payment, you may cancel by writing to: Continental Stock Transfer & Trust Company, 2 Broadway, 19th Floor, New York, NY 10004. We must receive your written cancellation instructions by the business day preceding the investment date.

19. What reports will you send to me?

    We will send you a statement of account at least once each quarter showing amounts invested, purchase prices, shares purchased, and other information for the year to date. Each year, the fourth quarter statement with summary will reflect year-to-date information, which you should retain for your records. We also will send you a Form 1099 for income tax purposes.

    We will send you copies of the same communications sent to all shareholders, including our Annual Report and the Notice of Annual Meeting and Proxy Statement.

    We will send you all notices and reports to your last address of record with the administrator. Therefore, you must notify the administrator promptly in writing of any change of address, at: Continental Stock Transfer & Trust Company, 2 Broadway, 19th Floor, New York, NY 10004.

20. Will I receive dividends on shares held in my account?

    Yes. We will pay cash dividends on all shares of common stock held in your account on the basis of the number of full shares and fractional share interests you hold on the relevant record date. Your dividends will be automatically reinvested to purchase additional shares of common stock, which will be credited to your account.

6


21. Will I receive a certificate for shares held in my account?

    The shares you hold in your account will be registered in the name of the administrator or its nominee, and the number of shares credited to your account under the Plan will be shown on your quarterly statement. This protects against loss, theft, or destruction of stock certificates. Therefore, we will not issue you certificates for the shares held in your account unless you terminate your participation in the Plan or withdraw all or some of the shares from the your account.

22. How may I withdraw shares from my account?

    You may withdraw some or all of the shares from your account by completing the withdrawal form attached to your dividend reinvestment statement or requesting the administrator to do so, in writing. You should send those forms and requests to: Continental Stock Transfer & Trust Company, 2 Broadway, 19th Floor, New York, NY 10004. You will receive certificates for whole shares withdrawn, unless you request cash instead of share certificates. For further information on requesting cash instead of share certificates, see question 24, "Can I receive cash instead of share certificates when I withdraw shares or terminate my participation?" We will not issue a certificate for any fraction of a share; instead, we will pay you cash for any fraction of a share, based on the then-current market price. When you withdraw shares from your account and we issue you a certificate, those shares will continue to participate in the Plan as per your elections unless you direct otherwise.

23. How may I terminate my participation in the Plan?

    You may terminate your participation in the Plan at any time by sending the administrator a completed termination request form (which is attached to your dividend reinvestment statement), or simply by notifying the administrator in writing. You may send these notices to the administrator, at: Continental Stock Transfer & Trust Company, 2 Broadway, 19th Floor, New York, NY 10004.

    When you terminate your participation in the Plan, you will receive certificates for the whole shares credited to your account, unless you request cash instead of share certificates. For further information on requesting cash in lieu of share certificates, see question 24, "Can I receive cash instead of share certificates when I withdraw shares or terminate my participation?" We will not issue a certificate for any fraction of a share; instead, we will pay you cash for any fraction of a share, based on the then-current market price.

    If we receive your termination request less than ten business days before a dividend record date, but before the dividend payment date, your termination will not be effective until after we have credited that dividend to your account.

24. Can I receive cash instead of share certificates when I withdraw shares or terminate my participation?

    Yes. If you want to receive cash instead of share certificates when you withdraw shares from your account or terminate your participation in the Plan, you may request the administrator, as your agent, to sell those shares on the open market and to send you the net proceeds. You may send your sale instructions to the administrator, at: Continental Stock Transfer & Trust Company, 2 Broadway, 19th Floor, New York, NY 10004.

    The administrator usually makes sales under the Plan once a week, on the last trading day of the week, although the administrator may do so more frequently, such as in response to an unusually high volume of sales requests. The administrator must receive your written sale instructions by the close of business on the second business day before the sale date. In other words, in most cases the administrator must receive your sale instructions by 5:00 p.m. on Wednesday in order to have the administrator sell your shares on that Friday. If you are requesting cash in connection with terminating

7


your participation in the Plan, and the administrator receives your sale instructions on or after a dividend record date but before the dividend payment date, the administrator will not process your sale until that dividend has been credited to your account.

    Your net proceeds will equal the sale price of your shares less brokerage commissions, a service fee charged by the administrator, and any applicable taxes to be paid or withheld by the administrator.

25. How will the shares in my Plan account be held?

    The shares of common stock that you purchase under the Plan will be registered in the name of the administrator or its nominee, and the administrator will keep an individual account for you to record your interest in these shares.

26. Does the Plan provide for safekeeping of shares?

    Yes. The Plan automatically provides for safekeeping of shares purchased through the Plan, whether by initial purchase, dividend reinvestment or optional payment, unless and until you withdraw those shares from your account. There is no charge for this service.

    You also may at any time deposit with the administrator for safekeeping certificates for other shares of common stock that you hold of record and that participate in the Plan, including shares that you acquired other than through the Plan and shares that you previously withdrew from your Plan account. If you want to use this safekeeping feature, you should send the certificates to the administrator, together with a written request that the shares be held in safekeeping. For better security, we suggest that you send these certificates by registered mail, return receipt requested, and insure them in an amount sufficient to cover the bond premium that would be charged to replace the certificates if they were lost or destroyed.

    The administrator will register those shares in its or its nominee's name and show those shares separately in your Plan account, but as with other shares in your Plan account you will remain the beneficial owner of those shares. The administrator currently does not charge any fees in connection with such an account, but may impose a fee (or increase its fee) for this service at any time.

27. May I transfer shares between Plan accounts, or from my Plan account to someone else?

    Yes, you may transfer shares from one account in the Plan to another account in the Plan or may direct that shares be issued from your account to another person. You must complete and provide to the administrator any forms that it requires for such a transfer or issuance.

28. What happens if I transfer or sell all of the shares registered in my name?

    If you dispose of all shares of common stock registered in your name in our shareholder records without terminating your participation in the Plan, we will continue to reinvest dividends on the shares in your Plan account. If you sell all of the shares of common stock you hold of record, you will still beneficially own the shares in your Plan account because the Plan administrator holds them as nominee. We will continue to reinvest your cash dividends on the shares in your Plan account until you withdraw any of those shares and specify that they are no longer to be held in the Plan, or terminate your participation in the Plan.

29. What happens if Pacific Century has a rights offering, stock dividend or stock split?

    Any common stock dividend or stock split on our common stock held in your Plan account will be credited to your Plan account. If you have common stock that is not held in your Plan account, we will mail all stock distributable to you as a result of those holdings in the ordinary manner.

8


    If we make available to shareholders rights or warrants to purchase additional shares of common stock or other securities, we will make them available to you based on the number of shares you own of record, as well as the number of shares you hold in your Plan account (including fractional share interests to the extent practicable) on the relevant record date.

    If we have a stock split, stock dividend or other similar transaction, the number of shares of common stock covered by this prospectus will be increased accordingly.

30. How will my shares be voted at a shareholders' meeting?

    Our proxy agent will forward all proxy materials to you by electronic means or by mail, including a form of proxy covering all shares you own of record and all shares held in your Plan account. You may vote those shares by proxy, or you may vote them in person at the meeting. If you send in a completed, signed proxy card, but do not give us instructions as to how to vote for a particular matter, all shares in your Plan account will be voted in accordance with the recommendations of Pacific Century's management. If you do not return a proxy card or it is not signed, none of your shares will be voted unless you vote in person at the meeting.

31. May I pledge or encumber the shares in my Plan account?

    You may not pledge or encumber the shares in your Plan account while they are in that account. If you want to pledge or encumber those shares, you must request that they be withdrawn from your account and obtain a share certificate in your own name.

32. What are the material Federal income tax consequences of participation in the Plan?

    If you elect to reinvest the cash dividends on all or part of your shares of common stock in additional shares of common stock, you will be treated for Federal income tax purposes as having received dividend income equal to the fair market value of the shares of common stock purchased with the reinvested dividends on the dividend payment date. The fair market value may be more or less than the actual price paid, because the share price fluctuates and may have been higher or lower during the pricing period than on the day when the shares are purchased. Your tax basis in the shares of common stock purchased with the reinvested dividends will equal the fair market value of the shares as of the dividend payment date and your holding period for those shares will begin on the day after the dividend payment date. Shareholders who do not elect to have dividends reinvested will continue to recognize dividend income equal to the amount of cash received on the dividend payment date.

    If you elect to invest in additional shares by making optional payments, you will be treated for Federal income tax purposes as having received a dividend equal to the excess (if any) of the fair market value on the investment date of the shares purchased, over the optional payment made. The fair market value may be more or less than the optional payment made because the share price fluctuates and may have been higher or lower during the pricing period than on the day when the shares are purchased. Your tax basis in the shares purchased will be equal to the amount you paid for the stock, plus the amount (if any) treated as a dividend for Federal income tax purposes, and your holding period for those shares will begin on the day after the investment date.

    You will not realize any taxable income when you receive certificates for whole common shares that you withdraw from your Plan account or any safekeeping account, whether you request those certificates or receive them upon termination of your participation in the Plan or termination of the Plan. However, you will realize a gain or loss when your common stock is sold or exchanged. When you receive a cash payment instead of shares or for a fraction of a share, the amount of your gain or loss will be the difference between the amount you receive for the share or fraction, and your tax basis in that share or fraction.

9


    If your dividends are subject to United States income tax withholding (including if you are a foreign stockholder), we will deduct the amount of the tax that is subject to withholding deducted from your dividends before reinvestment in additional shares for your Plan account. Statements confirming purchases made for these participants will indicate that tax has been withheld. Pursuant to Internal Revenue Service regulations, the amount of tax to be withheld will be determined by applying the applicable withholding rate to an amount equal to the amount of cash dividends that the participant would have received had the dividends been paid to the participant in cash.

    This discussion is intended only as a general discussion of the current Federal income tax consequences of participation in the Plan. We advise you to consult with your own tax advisor as to the tax implications of your participation in the Plan, including the effect of any changes in law or regulation after the date of this prospectus.

33. What is the responsibility of the Pacific Century and the administrator?

    The Plan provides that neither Pacific Century, the administrator, nor any of their representatives, employees, or agents will be liable for acts or omissions undertaken in good faith, including with respect to acts occurring before you terminate your participation in the Plan, and the prices at which shares are purchased or sold for your account and the times those purchases and sales are made. These provisions do not preclude your exercise of any rights under Federal or state securities laws.

34. May the Plan be changed or terminated?

    We reserve the right to suspend, modify, or terminate the Plan at any time. We will notify affected participants of any suspension, termination, or material modification of the Plan. If we terminate the Plan, we will issue you certificates for whole shares credited to your Plan account and any safekeeping account, and pay you in cash for any fraction of a share in your Plan account.

10



Use of Proceeds

    The net proceeds from the sale of the shares of common stock offered under the Plan will be used for general corporate purposes of Pacific Century, which may include the reduction of indebtedness, investments at the holding company level, investments in, or extensions of credit to, our banking and nonbanking subsidiaries and other banks and companies engaged in other financial service activities, the purchase of our outstanding equity securities, and possible acquisitions. Pending such use, the net proceeds may be temporarily invested. The precise amounts and timing of the application of net proceeds will depend upon our funding requirements and the availability of other funds. Based upon our past and anticipated growth, we may engage in additional financings of a character and amount to be determined as the need arises.

    Carlsmith Ball LLP, Honolulu, Hawaii, will pass on the validity of the common stock to be offered hereunder.

    We estimate the expenses to be incurred in connection with the issuance and distribution of the securities being registered as follows:

Registration statement filing fee   $ 6,237.50
Legal fees and expenses     15,000.00

Item 15. Indemnification of Directors and Officers.

    Section 145 of the Delaware General Corporation Law (the "DGCL") authorizes a Delaware corporation to indemnify its directors, officers, employees and agents against certain liabilities and expenses they may incur in such capacities, and provides that such persons have a right to indemnification against expenses where they have been successful on the merits or otherwise in defense of certain types of actions or any claim, issue or matter therein. The indemnification provided by Section 145 is not exclusive of any other indemnification rights that may exist under any bylaw, agreement, vote of shareholders or disinterested directors, or otherwise. Article VI of the registrant's bylaws require that the registrant indemnify and hold harmless, to the fullest extent permitted by applicable law (including circumstances in which indemnification is otherwise discretionary) any person who was or is made or is threatened to be made a party to or is otherwise involved in any action, suit or proceeding by reason of the fact that such person is or was a director or officer of the registrant or is or was serving at its request as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust, enterprise or nonprofit entity (including service with respect to employee benefit plans) against all liability and loss suffered and expenses (including attorneys' fees) reasonably incurred by such person. In addition, the registrant maintains insurance under which its directors, officers and employees and agents are insured against certain liabilities. Also, the registrant's Certificate of Incorporation includes provisions which eliminate the personal liability of registrant's directors for monetary damages resulting from breaches of their fiduciary duty of care, provided that such provision does not eliminate liability for breaches of the duty of loyalty, acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, violations of Sections 174 of the DGCL (concerning the willful or negligent violation of statutory provisions precluding payment of certain dividends and certain stock purchases or redemptions) or for any other transactions from which the director derived an improper personal benefit.

Item 17. Undertakings.

    The undersigned registrant hereby undertakes:

    (a) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

    Provided, however, that the undertakings set forth in paragraphs (a)(i) and (a)(ii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act") that are incorporated by reference in this registration statement.

    (b) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

    (c) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

    (d) For purposes of determining any liability under the Securities Act, each filing of the registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act that is incorporated by reference in the registration statement) shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

    (e) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

EXHIBIT INDEX

EXHIBIT 4.1 PACIFIC CENTURY FINANCIAL CORPORATION DIVIDEND REINVESTMENT AND STOCK PURCHASE PLAN(1) SECTION 1. NAME AND NUMBER OF SHARES. The dividend reinvestment and stock purchase plan of Pacific Century Financial Corporation ("Pacific Century") shall be known as the Dividend Reinvestment and Stock Purchase Plan (the "Plan"). The number of shares of common stock, par value $.01, of Pacific Century ("Common Stock") that may be issued pursuant to the Plan shall be fixed from time to time by the Board of Directors of Pacific Century. SECTION 2. ADMINISTRATION AND COSTS. The administrator of the Plan (the "Administrator"), who shall administer the Plan for participants, keep records, send statements of accounts to participants, and perform other duties relating to the Plan, shall be appointed from time to time by the Board of Directors of Pacific Century, but as of the date hereof shall be Continental Stock Transfer and Trust Company. SECTION 3. INITIAL STOCK PURCHASE. An employee, retired employee, or director of Pacific Century or any member of the controlled group of corporations (as defined in Section 1563(a) of the Internal Revenue Code of 1986, as amended) of which Pacific Century is a member (an "Eligible Employee") who is not a stockholder of record or a beneficial owner of Common Stock participating in the Plan may become a participant in the Plan by purchasing shares of Common Stock pursuant to a Pacific Century-approved initial stock purchase form. Such forms shall be made available by and upon execution shall be returned to the Administrator. An individual who is a resident of the State of Hawaii and who is not a stockholder of record or a beneficial owner of Common Stock participating in the Plan may become a participant in the Plan by purchasing shares of Common Stock pursuant to a Pacific Century-approved initial stock purchase form. Such forms shall be made available by and upon execution shall be returned to the Administrator. This paragraph shall be effective only upon the written approval by the Chairman of the Board of Pacific Century, which approval may be revoked at any time. An initial stock purchase of not less than $250 may be made by enclosing a check or money order with the applicable initial stock purchase form. No interest shall be paid on initial stock purchase payments prior to their investment in Common Stock. Checks must clear before they will be applied to the purchase of Common Stock. A person making a purchase of Common Stock under this Section 3 shall be a participant in the Plan and shall be eligible thereafter to make optional payments pursuant to the Plan. - ------------------------ (1) This version of the Plan adds to the version in effect on July 28, 1994 all changes adopted from that date through June 22, 2001.

Initial stock purchase payments and optional payments may not exceed an aggregate of $5,000 per calendar quarter. SECTION 4. DIVIDEND REINVESTMENT AND OPTIONAL PAYMENTS. All holders of record of Common Stock shall be eligible to join the Plan at any time. Each participant in the Plan shall remain a participant until he or she withdraws from the Plan. An eligible shareholder may join the Plan by completing and signing the Pacific Century-approved authorization form (an "Authorization Form"). Authorization Forms shall be made available by and upon execution shall be returned to the Administrator. The Authorization Form shall permit an eligible shareholder to participate in the Plan by checking the appropriate box. The shareholder may elect one of the following enrollment options. First, the shareholder may elect to reinvest dividends paid on all of the shares of Common Stock registered in his name, in which case the shareholder may also purchase stock with optional cash payments. Second, the shareholder may elect to reinvest dividends paid on a portion of the shares of Common Stock registered in his name, in which case the shareholder may also purchase stock with optional cash payments. Third, the shareholder may elect to participate in the Plan by making optional cash payments only. However, any shares acquired by making optional cash payments will automatically participate in the Plan, so dividends on those shares will be automatically reinvested. Shareholders of record of Common Stock, or persons or entities who become participants in the Plan pursuant to Section 3, who submit a completed and signed Authorization Form shall be eligible to make optional cash payments of not less than $25 at any time. An initial optional payment of not less than $25 may be made by a participant when enrolling by enclosing a check or money order with the Authorization Form. Thereafter, optional payments of not less than $25 may be made at any time and the amount may be varied each time, subject, however, to the maximum limit on optional payments per calendar quarter. No interest shall be paid on optional payments prior to their investment in Common Stock. Checks must clear before they will be applied to the purchase of Common Stock. Optional payments may not exceed an aggregate of $5,000 per calendar quarter. SECTION 5. PURCHASE AND ACCOUNT RULES. Cash dividends on Common Stock participating in the Plan shall be applied to the purchase of additional Common Stock on behalf of the participants on dividend payment dates, as and to the extent elected by the participant. To reinvest cash dividends, an Authorization Form must be received by the Administrator at least ten business days before the dividend record date on which it is to become effective. In order to be invested in any particular calendar month, any initial purchase payment or optional payment must be received by the Administrator on or before the last business day of the preceding calendar month. If the payment is received timely, it shall be applied to the purchase of additional shares of Common Stock (i) on the dividend payment date, if a dividend is payable 2

in that calendar month, or (ii) on the tenth business day of the calendar month, if no dividend is payable in that month. However, any payment received more than thirty-five days prior to the applicable investment date will be returned. A participant may arrange for the monthly deduction of optional payments from his or her checking or savings account by completing and returning to the Administrator a Pacific Century-approved authorization to charge deposit account form. The price of shares of Common Stock purchased under the Plan shall be 100% of the market price. For purposes of the Plan, "market price" shall be determined on the basis of the average of the last sale prices for a share of Common Stock on the New York Stock Exchange for the period of five trading days ending on the day of purchase. If there is no trading in the Common Stock during any trading day in the five-day period, the market price and the purchase price based thereon shall be determined by the management of Pacific Century on the basis of such market quotations as shall be deemed appropriate. In no event, however, shall the purchase price be less than the par value of the Common Stock. Each participant's account shall be credited with that number of shares, including fractions computed to four decimal places, equal to the total amount to be invested, divided by the applicable purchase price per share. Shares of Common Stock purchased under the Plan shall be registered in the name of the Administrator or a nominee selected by the Administrator and held as agent for the participants. The Administrator shall receive dividends for all shares of Common Stock that a participant holds in his or her Plan account as of the dividend record date, shall credit such dividends to the participants' accounts on the basis of full and fractional shares held in these accounts, and shall automatically reinvest those cash dividends in additional shares of Common Stock at 100% of the market price. Share certificates shall not be issued to participants except as set forth in Sections 7 and 8 hereof. In the case of dividends on Common Stock subject to United States income tax withholding, the amount of tax to be withheld shall be deducted from the amount of dividends on Common Stock to determine the amount of dividends to reinvest. SECTION 6. REPORTS TO PARTICIPANTS. Participants shall receive quarterly statements of account showing amounts invested, purchase prices and shares purchased for the year to date. In addition, each participant shall receive copies of Pacific Century's annual report, proxy statement, and information for income tax reporting purposes. 3

SECTION 7. CHANGE IN OR TERMINATION OF PARTICIPATION IN PLAN. A participant may change the terms of his participation in the Plan at any time by completing and signing a new Authorization Form and returning it to the Administrator. Any change with respect to reinvestment of dividends must be received at least ten business days before the dividend record date for which the dividend is to be paid. A participant may terminate participation in the Plan at any time by completing a Pacific Century-approved termination request form, or by notifying the Administrator in writing. However, if the termination request is received less than ten business days before a dividend record date, but before a dividend payment date, the termination will not be processed until after the dividend has been credited to the participant's account. Upon such a termination of participation, certificates for whole shares credited to the participant's account shall be issued and a cash payment shall be made for any fraction of a share. The cash payment for any fraction of a share shall be based on the then-current market price per share. If a participant wishes to receive cash in lieu of shares upon termination of participation in the Plan, the participant may request the Administrator (as agent for the participant) to sell the shares credited to the participant's account on the open market and remit the net proceeds to the participant. Such requests may be made directly to the Administrator. Such sales will be made periodically on a schedule set by the Administrator, in its discretion. In order for his or her shares to be eligible for sale on a sale date, the sale request must be received by the close of business on the second business day before the sale date. Further, if the sale request is received after a dividend record date but before a dividend payment date, the sale will not be processed until after the dividend has been credited to the participant's account. The net proceeds from any such sale shall equal the sales price of the shares less brokerage commission, the service fee of the Administrator charged in connection with such sale, and any applicable taxes to be paid by or withheld by the Administrator. Any fractional shares credited to the participant's account shall not be sold but shall be converted to cash on the basis of the then current market price. SECTION 8. WITHDRAWAL OR TRANSFER OF SHARES IN THE PLAN. A participant may withdraw all or a portion of shares of Common Stock from his account by notifying the Administrator in writing to that effect and specifying the number of shares to be withdrawn. Certificates for whole shares of Common Stock so withdrawn shall be issued, but in no case shall certificates for fractional shares be issued. If a participant wishes to receive cash in lieu of shares upon such a withdrawal, the participant may request the Administrator (as agent for the participant) to sell the shares credited to the participant's account on the open market and remit the net proceeds to the participant. Such requests may be made directly to the Administrator. Such sales will be made periodically on a schedule set by the Administrator, in its discretion. In order for his or her shares to be eligible for sale on a sale date, the sale request must be received by the close of business on the second business day before the sale date. The net proceeds shall equal the sales price of the 4

shares less brokerage commission, the service fee of the Administrator charged in connection with such sale, and any applicable taxes to be paid by or withheld by the Administrator. Any remaining shares and fractions thereof shall continue to be credited to the participant's account. Pursuant to such rules as the Administrator and Pacific Century may agree upon from time to time, a participant may transfer shares from one account in the Plan to another account in the Plan or may direct that shares be issued from the participant's account in the Plan to another person. Any such transfer or issuance must be made upon such forms as the Administrator may require. SECTION 9. MISCELLANEOUS MATTERS RELATING TO ACCOUNTS. If a participant disposes of all of the shares of Common Stock registered in his or her own name, unless the participant also withdraws all shares held in his account under the Plan, the Administrator shall continue to reinvest the dividends on the shares held in the participant's Plan account. Such a participant may continue to make optional cash payments so long as shares are held in his or her account under the Plan. If a participant has an account in the Plan, all stock distributable to such participant as a result of a stock dividend or stock split by Pacific Century on its Common Stock (including stock distributable on shares of Common Stock that participate in the Plan but are not held of record by the Administrator) shall be credited to the participant's account in the Plan. If Pacific Century makes available to holders of Common Stock rights or warrants to purchase additional shares of Common Stock or other securities, then they will also be made available to participants based on the number of shares held of record, as well as the number of shares held in any Plan account (including fractional shares, to the extent practicable) on the relevant record date. Shares credited to a participant's account under the Plan may not be pledged or encumbered by a participant. Neither Pacific Century, the Administrator, nor any representative, employee, or agent of Pacific Century or the Administrator shall be liable under the Plan for any act done in good faith or for any good faith omissions to act, including (but not limited to) any claims of liability (i) arising out of any such act or omission to act that occurs prior to a participant's terminating participation pursuant to the terms of the Plan, and (ii) with respect to the prices at which shares are purchased for a participant's account and the times such purchases are made. All shares of Common Stock credited to the participant's account under the Plan shall be voted as the participant directs on a proxy card. If no instructions are received on a signed proxy card, all of the participant's shares shall be voted in accordance with the recommendations of Pacific Century's management. If the proxy card is not returned or if it is returned unsigned, none of the participant's shares shall be voted unless the participant votes in person. 5

SECTION 10. AMENDMENT, SUSPENSION, AND REINSTITUTION OF PLAN. Pacific Century currently intends to continue the Plan indefinitely, but reserves the right to suspend or terminate the Plan at any time. Pacific Century also reserves the right to make any additions or modifications to the Plan. The Chairman of the Board of Pacific Century may suspend the Plan at any time, may interpret the Plan, and may make additions or modifications thereto that are not inconsistent with the above provisions of the Plan. In the event of a suspension of the Plan, the Chairman of the Board of Pacific Century may determine the date, if any, on which the Plan shall be reinstituted. In the event that the number of shares of Common Stock to be purchased by the participants in the Plan exceeds the balance of the shares authorized by the Board of Directors to be sold pursuant to the Plan, then the Plan shall be automatically suspended with respect to future purchases until such time as the Board of Directors of Pacific Century has authorized additional shares of Common Stock to be sold pursuant to the Plan. In the event of automatic suspension of the Plan as provided in the preceding paragraph, then (i) on the date of such automatic suspension of the Plan, the number of shares of Common Stock to be sold shall be prorated among the participants purchasing shares on such date, and (ii) the Chairman of the Board of Pacific Century shall determine the date of the commencement of the Plan after the Board of Directors has authorized the sale of additional shares of Common Stock pursuant to the Plan. SECTION 11. PROFIT SHARING PLAN MEMBERS. For purposes of this Plan, each member of the Bank of Hawaii Profit Sharing Plan who has an interest in the Pacific Century Stock Fund of said profit sharing plan shall be regarded as a holder of record of Common Stock and an Eligible Employee, so that he or she will be eligible to to make optional cash payments. SECTION 12. SAFEKEEPING OF SHARES. In accordance with such procedures as the Administrator may adopt from time to time, a participant may deliver to the Administrator certificates for shares of Common Stock participating in the Plan of which the participant is the record holder. The Administrator shall register such shares in its or its nominee's name and shall reflect those shares separately in the participant's Plan account to record the participant's beneficial ownership of such shares. The Administrator shall charge the participant, and the participant shall be liable for, such fees as the Administrator shall impose, for these safekeeping services. 6

We have assumed, without further investigation, the following: (a) all agreements contemplated by the Registration Statement, the Prospectus and the Plan with respect to offer, issuance, sale and delivery by the Company of the shares of Common Stock and the purchase of such shares by the purchasers thereof, all as contemplated by the Registration Statement, the Prospectus and the Plan, are or will be enforceable against the respective parties thereto, each in accordance with its terms; (b) each document submitted to us for review is accurate and complete, each such document that is an original is authentic, each such document that is a copy conforms to an authentic original, and all signatures on each such document are genuine; and (c) each certificate issued by a government official concerning a person or entity's property or status is accurate, complete and authentic and all official public records (including their proper indexing and filing) are accurate and complete.
