TUCKER ANTHONY INCORPORATED

The date of this Prospectus is ___________, 1998.


State Street Bank and Trust Company is the Property Trustee (as defined herein) of the Trust. The Trust exists for the purpose of issuing the Preferred Securities and investing the proceeds thereof in an equivalent amount of % Junior Subordinated Debentures (the "Junior Subordinated Debentures") of the Company. The Junior Subordinated Debentures will mature on June 30, 2029, which date may be shortened to a date not earlier than June 30, 2003, if certain conditions are met (including, in the case of shortening the Stated Maturity (as defined herein), the Company having received prior approval of the Board of Governors of the Federal Reserve System ("Federal Reserve") to do so if then required under applicable capital guidelines or policies of the Federal Reserve). The Preferred Securities will have a preference over the Common Securities under certain circumstances with respect to cash distributions and amounts payable on liquidation, redemption or otherwise. See "Description of the Preferred Securities--Subordination of the Common Securities."

Holders of Preferred Securities are entitled to receive preferential cumulative cash distributions, at the annual rate of __% of the liquidation amount of $10 per Preferred Security (the "Liquidation Amount"), accruing from May __, 1998, the date of original issuance, and payable quarterly in arrears on the last day of March, June, September and December of each year, commencing September 30, 1998 (the "Distributions"). The Company has the right, so long as no Debenture Event of Default (as defined herein) has occurred and is continuing, to defer payment of interest on the Junior Subordinated Debentures at any time or from time to time for a period not to exceed 20 consecutive quarters with respect to each deferral period (each, an "Extension Period"); provided that no Extension Period may extend beyond the Stated Maturity of the Junior Subordinated Debentures. Upon the termination of any such Extension Period and the payment of all amounts then due, the Company may elect to begin a new Extension Period subject to the requirements set forth herein. If interest payments on the Junior Subordinated Debentures are so deferred, Distributions on the Preferred Securities will also be deferred, and the Company will not be permitted, subject to certain exceptions described herein, to declare or pay any cash distributions with respect to its capital stock or debt securities that rank pari passu with or junior to the Junior Subordinated Debentures. DURING AN EXTENSION PERIOD, INTEREST ON THE JUNIOR SUBORDINATED DEBENTURES WILL CONTINUE TO ACCRUE (AND THE AMOUNT OF DISTRIBUTIONS TO WHICH HOLDERS OF THE PREFERRED SECURITIES ARE ENTITLED WILL ACCUMULATE) AT THE RATE OF ___% PER ANNUM, COMPOUNDED QUARTERLY, AND HOLDERS OF THE PREFERRED SECURITIES WILL BE REQUIRED TO INCLUDE INTEREST INCOME IN THEIR GROSS INCOME FOR UNITED STATES FEDERAL INCOME TAX PURPOSES IN ADVANCE OF RECEIPT OF THE CASH DISTRIBUTIONS WITH RESPECT TO SUCH DEFERRED INTEREST PAYMENTS. UPON THE OCCURRENCE OF AN EXTENSION PERIOD, A HOLDER OF PREFERRED SECURITIES THAT DISPOSES OF ITS PREFERRED SECURITIES BETWEEN RECORD DATES FOR PAYMENTS OF DISTRIBUTIONS (AND CONSEQUENTLY DOES NOT RECEIVE A DISTRIBUTION FROM THE TRUST FOR THE PERIOD PRIOR TO SUCH DISPOSITION) WILL NEVERTHELESS BE REQUIRED TO INCLUDE ACCRUED BUT UNPAID INTEREST ON THE JUNIOR SUBORDINATED DEBENTURES THROUGH THE DATE OF DISPOSITION IN INCOME AS ORDINARY INCOME AND TO ADD SUCH AMOUNT TO ITS ADJUSTED TAX BASIS IN ITS PRO RATA SHARE OF THE UNDERLYING JUNIOR SUBORDINATED DEBENTURES DEEMED DISPOSED OF. See
"Description of the Junior Subordinated Debentures--Option to Extend Interest Payment Period," "Certain Federal Income Tax Consequences--Potential Extension of Interest Payment Period and Original Issue Discount" and "--Disposition of Preferred Securities."

The Company and the Trust believe that, taken together, the obligations of the Company under the Guarantee, the Trust Agreement, the Junior Subordinated Debentures, the Indenture and the Expense Agreement (each as defined herein) provide, in the aggregate, a full, irrevocable and unconditional guarantee, on a subordinated basis, of all of the obligations of the Trust under the Preferred Securities. See "Relationship Among the Preferred Securities, the Junior Subordinated Debentures and the Guarantee--Full and Unconditional Guarantee." The Guarantee of the Company guarantees the payment of Distributions and payments on liquidation or redemption of the Preferred Securities, but only in each case to the extent of funds held by the Trust, as described herein. See "Description of the Guarantee--General." If the Company does not make interest payments on the Junior Subordinated Debentures held by the Trust, the Trust will have insufficient funds to pay Distributions on the Preferred Securities. The Guarantee does not cover payments of Distributions when the Trust does not have sufficient funds to pay such Distributions. In such event, a holder of Preferred Securities may institute a legal proceeding directly against the Company pursuant to the terms of the Indenture to enforce payments of amounts equal to such Distributions to such holder. See "Description of the Junior Subordinated Debentures--Enforcement of Certain Rights by Holders of the Preferred Securities." The obligations of the Company under the Guarantee and the Preferred Securities are subordinate and junior in right of payment to all Senior Debt, Subordinated Debt and Additional Senior Obligations (each as defined herein) of the Company. The Junior Subordinated Debentures are unsecured obligations of the Company and are subordinated to all Senior Debt, Subordinated Debt and Additional Senior Obligations of the Company.

2

The Preferred Securities are subject to mandatory redemption, in whole or in part, upon repayment of the Junior Subordinated Debentures at maturity or their earlier redemption. Subject to Federal Reserve approval, if then required under applicable capital guidelines or policies of the Federal Reserve, the Junior Subordinated Debentures are redeemable prior to maturity at the option of the Company (i) on or after June 30, 2003, in whole at any time or in part from time to time, or (ii) at any time, in whole (but not in part), within 180 days following the occurrence of a Tax Event, a Capital Treatment Event or an Investment Company Event (each as defined herein), in each case at a redemption price equal to the accrued and unpaid interest on the Junior Subordinated Debentures so redeemed to the date fixed for redemption, plus 100% of the principal amount thereof. See "Description of the Preferred Securities--Redemption or Exchange."

The Company intends to take the position that the Junior Subordinated Debentures will be classified under current law as indebtedness of the Company for United States federal income tax purposes and accordingly, the Company intends to treat the interest payable by the Company on the Junior Subordinated Debentures as deductible for United States federal income tax purposes. There is no assurance that such position of the Company will not be challenged by the Internal Revenue Service or, if challenged, that such a challenge will not be successful. See "Risk Factors-Proposed Tax Legislation".

The Company has the right at any time to dissolve the Trust, subject to the Company having received prior approval of the Federal Reserve to do so if then required under applicable capital guidelines or policies of the Federal Reserve. In the event of the voluntary or involuntary dissolution of the Trust, after satisfaction of liabilities to creditors of the Trust as required by applicable law, the holders of Preferred Securities will be entitled to receive a Liquidation Amount of $10 per Preferred Security, plus accumulated and unpaid Distributions thereon to the date of payment, which may be in the form of a Junior Subordinated Debenture having an aggregate principal amount equal to the Liquidation Amount of such Preferred Securities (and carrying with it accrued interest in an amount equal to the accumulated and unpaid Distributions then due on such Preferred Securities), subject to certain exceptions. See "Description of the Preferred Securities--Redemption or Exchange" and "--Liquidation Distribution Upon Dissolution."

The Company will provide to the holders of the Preferred Securities quarterly reports containing unaudited financial statements and annual reports containing financial statements audited by the Company's independent auditors. The Company will also furnish annual reports on Form 10-K and quarterly reports on Form 10-Q free of charge to holders of the Preferred Securities who so request in writing addressed to the Clerk of the Company.

CERTAIN PERSONS PARTICIPATING IN THIS OFFERING MAY ENGAGE IN TRANSACTIONS THAT STABILIZE, MAINTAIN OR OTHERWISE AFFECT THE PRICE OF THE PREFERRED SECURITIES OFFERED HEREBY, INCLUDING OVER-ALLOTMENTS, STABILIZING TRANSACTIONS, SYNDICATE SHORT COVERING TRANSACTIONS AND PENALTY BIDS. SUCH TRANSACTIONS, IF COMMENCED, MAY BE DISCONTINUED AT ANY TIME. FOR A DESCRIPTION OF THESE ACTIVITIES, SEE "UNDERWRITING."

IN CONNECTION WITH THIS OFFERING, CERTAIN UNDERWRITERS (AND SELLING GROUP MEMBERS) MAY ENGAGE IN PASSIVE MARKET MAKING TRANSACTIONS IN THE PREFERRED SECURITIES OFFERED HEREBY ON THE NASDAQ STOCK MARKET'S NATIONAL MARKET IN ACCORDANCE WITH RULE 103 OF REGULATION M. SEE "UNDERWRITING."

The Company has sought to consistently increase earnings per share and to maximize return on equity through a combination of strategies, including:

o Personalized Service. The Company seeks to offer a full range of products and services to its customers while maintaining the high level of personalized service associated with a community bank. Strong, long-term relationships are a cornerstone of this strategy. The Company strives to respond quickly to customer needs and provides customers with direct access to senior lending officers with approval authority. The Company intends to use its community-based position to build its portfolio of commercial loans to small and medium-sized businesses.

o Growth through Strategic Acquisitions. The Company is in the process of completing the acquisition of Haymarket Cooperative Bank. See "Recent Developments" below. The Company continues to seek suitable strategic opportunities for consolidation and expansion of its market position through selective acquisitions.

RECENT DEVELOPMENTS

On December 10, 1997, the Company announced an agreement to acquire Haymarket Cooperative Bank. Haymarket, located in Boston, Massachusetts, has approximately $142 million of assets and will be acquired for approximately $20 million in cash. The Haymarket acquisition will add two branch locations in Boston's financial district, allowing the Company to provide commercial banking services to a greater number of Boston's small and medium-sized businesses. The acquisition will also connect the Bank geographically, giving it a market presence from Beverly on the North Shore of Massachusetts to Quincy and Braintree on the South Shore. The transaction is subject to federal and state regulatory approvals.

On April 14, 1998, the Company announced net income of $1,802,000 or $0.31 per share for the first quarter of 1998, compared to net income of $1,376,000, or $0.24 per share for the first quarter of 1997.

Total stockholders' equity was $55.3 million at March 31, 1998, compared to $48.4 million at March 31, 1997. The Company's leverage ratio at March 31, 1998, stood at 9.05%, compared to a leverage ratio of 8.62% on March 31, 1997. Book value at March 31, 1998 was $9.55 per share.

The Company's allowance for loan losses was $4.7 million, or 1.46% of loans outstanding at the end of the first quarter, compared to $4.3 million, or 1.46% of loans outstanding at March 31, 1997. Non-accruing loans totaled $1.5 million at March 31, 1998, compared to $1.7 million at the end of the previous quarter.

The Company's Board of Directors voted a regular quarterly dividend of 5 cents ($0.05) per share on the Company's Class A common stock, and 0.70 cents ($0.0070) per share on the Company's Class B common stock. The dividends were declared payable May 15, 1998 to stockholders of record on May 1, 1998.

                                         year, commencing September 30, 1998.  See "Description of the Preferred
                                         Securities-Distributions-Payment of Distributions."

Junior Subordinated Debentures......     The Trust will invest the proceeds from the issuance of the Preferred
                                         Securities and Common Securities in an equivalent amount of __% Junior

                                         Senior Debt and Subordinated Debt of the Company.  In addition, the
                                         Company's obligations under the Junior Subordinated Debentures will be
                                         structurally subordinated to all existing and future liabilities and
                                         obligations of its subsidiaries.

Option to Extend Interest
Payment Period......................     The Company has the right, at any time, so long as no Debenture Event
                                         of Default has occurred and is continuing, to defer payments of interest
                                         on the Junior Subordinated Debentures for a period not exceeding 20
                                         consecutive quarters; provided, that no Extension Period may extend
                                         beyond the Stated Maturity of the Junior Subordinated Debentures.  As
                                         a consequence of the extension by the Company of the interest payment
                                         period, quarterly Distributions on the Preferred Securities will be deferred
                                         (though such Distributions will continue to accrue with interest thereon
                                         compounded quarterly, since interest will continue to accrue and
                                         compound on the Junior Subordinated Debentures) during any such
                                         Extension Period.  During an Extension Period, the Company will be
                                         prohibited, subject to certain exceptions described herein, from declaring
                                         or paying any cash distributions with respect to its capital stock or debt
                                         securities that rank pari passu with or junior to the Junior Subordinated
                                         Debentures.  Upon the termination of any Extension Period and the
                                         payment of all amounts then due, the Company may commence a new
                                         Extension Period, subject to the foregoing requirements.  See
                                         "Description of the Preferred Securities--Distributions--Extension
                                         Period" and "Description of the Junior Subordinated Debentures--Option
                                         to Extend Interest Payment Period." Should an Extension Period occur,

8

                                         holders of Preferred Securities will be required to include deferred
                                         interest income in their gross income for United States federal income
                                         tax purposes in advance of receipt of the cash distributions with
                                         respect to such deferred interest payments. See "Certain Federal
                                         Income Tax Consequences--Potential Extension of Interest Payment
                                         Period and Original Issue Discount."

Redemption..........................     The Preferred Securities are subject to mandatory redemption, in whole
                                         or in part, upon repayment of the Junior Subordinated Debentures at
                                         maturity or their earlier redemption.  Subject to Federal Reserve approval,
                                         if then required under applicable capital guidelines or policies of the
                                         Federal Reserve, the Junior Subordinated Debentures are redeemable
                                         prior to maturity at the option of the Company (i) on or after June 30,
                                         2003, in whole at any time or in part from time to time, or (ii) at any time,
                                         in whole (but not in part), within 180 days following the occurrence of a
                                         Tax Event, a Capital Treatment Event or an Investment Company Event,
                                         in each case at a redemption price equal to 100% of the principal amount
                                         of the Junior Subordinated Debentures, together with any accrued but
                                         unpaid interest on the Junior Subordinated Debentures to the date fixed
                                         for redemption.  See "Description of the Junior Subordinated
                                         Debentures--Redemption or Exchange."

Ranking.............................     The Preferred Securities will rank pari passu, and payments thereon will
                                         be made pro rata, with the Common Securities except as described under
                                         "Description of the Preferred Securities--Subordination of Common
                                         Securities."  The Junior Subordinated Debentures will rank pari passu
                                         with all other Junior Subordinated Debentures (if any) issued by the
                                         Company (the "Other Debentures"), which are issued and sold (if at all)
                                         to other trusts established by the Company (if any), in each case similar
                                         to the Trust ("Other Trusts"), and will constitute unsecured obligations of
                                         the Company and will rank subordinate and junior in right of payment to
                                         all Senior Indebtedness to the extent and in the manner set forth in the
                                         Indenture.  See "Description of Junior Subordinated Debentures." The
                                         Guarantee will rank pari passu with all other guarantees (if any) issued
                                         by the Company with respect to Preferred Securities (if any) issued by
                                         Other Trusts ("Other Guarantees") and will constitute an unsecured
                                         obligation of the Company and will rank subordinate and junior in right
                                         of payment to all Senior Indebtedness to the extent and in the manner set
                                         forth in the Guarantee Agreement.  See "Description of Guarantee." In
                                         addition, because the Company is a holding company, the Junior
                                         Subordinated Debentures and the Guarantee will be effectively
                                         subordinated to all existing and future liabilities of the Company's
                                         subsidiaries, including the Bank's deposit liabilities.  See "Description of
                                         Junior Subordinated Debentures--Subordination."

Distribution of Junior
Subordinated Debentures.............     The Company has the right at any time to dissolve the Trust and cause the
                                         Junior Subordinated Debentures, after satisfaction of liabilities to
                                         creditors of the Trust as required by applicable law, to be distributed to
                                         holders of Preferred Securities in liquidation of the Trust, subject to the
                                         Company having received prior approval of the Federal Reserve to do so
                                         if then required under applicable capital guidelines or policies of the

9

                                         Federal Reserve.  See "Description of the Preferred Securities--
                                         Redemption or Exchange" and "Description of the Preferred
                                         Securities--Liquidation Distribution Upon Dissolution."

Guarantee...........................     The Company has guaranteed the payment of Distributions and payments
                                         on liquidation or redemption of the Preferred Securities, but only in each
                                         case to the extent of funds held by the Trust, as described herein.  The
                                         Company and the Trust believe that, taken together, the obligations of the
                                         Company under the Guarantee, the Trust Agreement, the Junior
                                         Subordinated Debentures, the Indenture and the Expense Agreement
                                         provide, in the aggregate, a full, irrevocable and unconditional guarantee,
                                         on a subordinated basis, of all of the obligations of the Trust under the
                                         Preferred Securities.  The obligations of the Company under the
                                         Guarantee and the Preferred Securities are subordinate and junior in right
                                         of payment to all Senior Debt, Subordinated Debt and Additional Senior
                                         Obligations of the Company.  If the Company does not make principal or
                                         interest payments on the Junior Subordinated Debentures, the Trust will
                                         not have sufficient funds to make distributions on the Preferred Securities.
                                         In such event, the Guarantee will not apply to such Distributions until the
                                         Trust has sufficient funds available therefor.  See "Description of the
                                         Guarantee."

Voting Rights.......................     The holders of the Preferred Securities will have no voting rights except
                                         in limited circumstances.  See "Description of the Preferred Securities --
                                         Voting Rights; Amendment of Trust Agreement."

Use of Proceeds.....................     All of the proceeds from the sale of the Trust Securities will be invested
                                         by the Trust in the Junior Subordinated Debentures.  The Company
                                         intends to use the net proceeds from the sale of the Junior Subordinated
                                         Debentures for general corporate purposes, including contributions to the
                                         Bank to fund its operations, the financing of one or more future
                                         acquisitions by the Company if and when suitable opportunities arise, and
                                         the repurchase of outstanding equity securities of the Company.  Initially,
                                         the net proceeds may be used to make short-term investment securities.

RISK FACTORS

Prospective investors should carefully consider, together with the other information contained and incorporated by reference in this Prospectus, the following risk factors in evaluating the Company and its business and the Trust before purchasing the Preferred Securities offered hereby. Prospective investors should note, in particular, that certain statements contained or incorporated by reference in this Prospectus, including, without limitation, statements containing the words "believes", "anticipates", "intends", "expects" and words of similar import, constitute "forward-looking statements" within the meaning of
Section 27A of the Securities Act and Section 21E of the Exchange Act. Such forward-looking statements involve known and unknown risks, uncertainties and other factors that may cause the actual results, performance or achievements of the Company to be materially different from any future results, performance or achievements expressed or implied by such forward-looking statements. Such factors include, among others, the following: general economic and business conditions in those areas in which the Company operates; demographic changes; competition; fluctuations in interest rates; changes in business strategy or development plans; changes in governmental regulation; credit quality; the availability of capital to fund the expansion of the Company's business; and other factors referenced in this Prospectus or incorporated by reference herein. Given these uncertainties, prospective investors are cautioned not to place undue reliance on such forward-looking statements. The Company disclaims any obligation to update any such factors or to publicly announce the results of any revisions to any of the forward-looking statements contained or incorporated by reference herein to reflect future events or developments. The considerations listed below represent certain important factors the Company believes could cause such results to differ. These considerations are not intended to represent a complete list of the general or specific risks that may affect the Company and the Trust. It should be recognized that other risks may be significant, presently or in the future, and the risks set forth below may affect the Company and the Trust to a greater extent than indicated.

RISK FACTORS RELATING TO THE PREFERRED SECURITIES

ABILITY TO MAKE PAYMENTS ON THE PREFERRED SECURITIES AND JUNIOR SUBORDINATED DEBENTURES

The Company is a legal entity separate and distinct from its subsidiaries, including the Bank. The ability of the Trust to pay amounts due on the Preferred Securities is solely dependent upon the Company making payments on the Junior Subordinated Debentures as and when required. As a holding company without significant assets other than its equity interest in the Bank, the Company's ability to pay interest on the Junior Subordinated Debentures to the Trust (and consequently, the Trust's ability to pay distributions on the Preferred Securities and the Company's ability to pay its obligations under the Guarantee) depends primarily on cash and liquid investments of the Company and upon cash dividends the Company may receive in the future from the Bank. The Bank's ability to pay dividends to the Company is restricted by Massachusetts law, which requires that retained earnings are available to pay such dividends. The Bank had retained earnings of $37.2 million at December 31, 1997, which amount of retained earnings is unrestricted and available for dividend payments to the Company. At December 31, 1997, the Company had cash, cash equivalents and securities available-for-sale of approximately $187.1 million. See "Use of Proceeds."

RANKING OF SUBORDINATED OBLIGATIONS UNDER THE GUARANTEE AND THE JUNIOR SUBORDINATED DEBENTURES

The obligations of the Company under the Guarantee issued for the benefit of the holders of Preferred Securities and under the Junior Subordinated Debentures are unsecured and rank subordinate and junior in right of payment to all Senior Debt, Subordinated Debt and Additional Senior Obligations of the Company, whether now existing or hereafter incurred. At December 31, 1997, the Company had no outstanding Senior Debt, Subordinated Debt or Additional Senior Obligations. Because the Company is a holding company, the right of

13

the Company to participate in any distribution of assets of the Bank upon the Bank's liquidation or reorganization or otherwise (and thus the ability of holders of the Preferred Securities to benefit indirectly from such distribution) is subject to the prior claims of creditors of the Bank, except to the extent that the Company may itself be recognized as a creditor of the Bank. The Junior Subordinated Debentures, therefore, will be effectively subordinated to all existing and future liabilities of the Bank and holders of Junior Subordinated Debentures and Preferred Securities should look only to the assets of the Company for payments on the Junior Subordinated Debentures. Neither the Indenture, the Guarantee nor the Trust Agreement places any limitation on the amount of secured or unsecured debt, including Senior Debt, Subordinated Debt and Additional Senior Obligations, that may be incurred by the Company. See "Description of the Guarantee--Status of the Guarantee" and "Description of the Junior Subordinated Debentures-- Subordination."

The ability of the Trust to pay amounts due on the Preferred Securities is solely dependent upon the Company making payments on the Junior Subordinated Debentures as and when required.

OPTION TO EXTEND INTEREST PAYMENT PERIOD; TAX CONSEQUENCES; MARKET PRICE CONSEQUENCES

The Company has the right under the Indenture, so long as no Debenture Event of Default has occurred and is continuing, to defer the payment of interest on the Junior Subordinated Debentures at any time or from time to time for a period not exceeding 20 consecutive quarters with respect to each Extension Period; provided that no Extension Period may extend beyond the Stated Maturity of the Junior Subordinated Debentures. As a consequence of any such deferral, quarterly Distributions on the Preferred Securities by the Trust will be deferred (and the amount of Distributions to which holders of the Preferred Securities are entitled will accumulate additional Distributions thereon at the rate of ____% per annum, compounded quarterly from the relevant payment date for such Distributions) during any such Extension Period. During any such Extension Period, the Company may not (i) declare or pay any dividends or distributions on, or redeem, purchase, acquire, or make a liquidation payment with respect to, any of the Company's capital stock, (ii) make any payment of principal, interest or premium, if any, on or repay, repurchase or redeem any debt securities of the Company that rank pari passu with or junior in interest to the Junior Subordinated Debentures or make any guarantee payments with respect to any guarantee by the Company of the debt securities of any subsidiary of the Company if such guarantee ranks pari passu with or junior in interest to the Junior Subordinated Debentures (other than payments under the Guarantee), or (iii) redeem, purchase or acquire less than all of the Junior Subordinated Debentures or any of the Preferred Securities. Prior to the termination of any such Extension Period, the Company may further defer the payment of interest; provided, that no Extension Period may exceed 20 consecutive quarters or extend beyond the Stated Maturity of the Junior Subordinated Debentures. Upon the termination of any Extension Period and the payment of all interest then accrued and unpaid (together with interest thereon at the annual rate of ____% compounded quarterly, to the extent permitted by applicable law), the Company may elect to begin a new Extension Period, subject to the above requirements. Subject to the foregoing, there is no limitation on the number of times that the Company may elect to begin an Extension Period. See "Description of the Preferred Securities--Distributions--Extension Period" and "Description of the Junior Subordinated Debentures--Option to Extend Interest Payment Period."

Should an Extension Period occur, each holder of Preferred Securities will be required to accrue and recognize income (in the form of original issue discount ("OID")) in respect of its pro rata share of the interest accruing on the Junior Subordinated Debentures held by the Trust for United States federal income tax purposes. A holder of Preferred Securities must, as a result, include such income in gross income for United States federal income tax purposes in advance of the receipt of cash, and will not receive the cash related to such income from the Trust if the holder disposes of the Preferred Securities prior to the record date for the payment of the related Distributions. See "Certain Federal Income Tax Consequences--Potential Extension of Interest Payment Period and Original Issue Discount."

The Company has no current intention of exercising its right to defer payments of interest by extending the interest payment period on the Junior Subordinated Debentures. Should the Company elect, however, to exercise such right in the future, the market price of the Preferred Securities is likely to be adversely affected. A holder

14

that disposes of its Preferred Securities during an Extension Period, therefore, might not receive the same return on its investment as a holder that continues to hold its Preferred Securities. As a result of the existence of the Company's right to defer interest payments, the market price of the Preferred Securities may be more volatile than the market prices of other securities on which original issue discount accrues that are not subject to such optional deferrals.

REDEMPTION DUE TO TAX EVENT, CAPITAL TREATMENT EVENT OR INVESTMENT COMPANY EVENT

The Company has the right to redeem the Junior Subordinated Debentures in whole (but not in part) within 180 days following the occurrence of a Tax Event, a Capital Treatment Event or an Investment Company Event (whether occurring before or after June 30, 2003), and, therefore, cause a mandatory redemption of the Preferred Securities. The exercise of such right is subject to the Company having received prior approval of the Federal Reserve to do so if then required under applicable capital guidelines or policies of the Federal Reserve.

"Tax Event" means the receipt by the Trust of an opinion of counsel experienced in such matters to the effect that, as a result of any amendment to, or change (including any announced prospective change) in the laws (or any regulations thereunder) of the United States or any political subdivision or taxing authority thereof or therein, or as a result of any official administrative pronouncement or judicial decision interpreting or applying such laws or regulations, which amendment or change is effective or which pronouncement or decision is announced on or after the date of issuance of the Preferred Securities under the Trust Agreement, there is more than an insubstantial risk that (i) the Trust is, or will be within 90 days of the date of such opinion, subject to United States federal income tax with respect to income received or accrued on the Junior Subordinated Debentures, (ii) interest payable by the Company on the Junior Subordinated Debentures is not, or, within 90 days of such opinion, will not be, deductible by the Company, in whole or in part, for United States federal income tax purposes, or (iii) the Trust is, or will be within 90 days of the date of the opinion, subject to more than a de minimis amount of other taxes, duties or other governmental charges. The Company must request and receive an opinion with regard to such matters within a reasonable period of time after it becomes aware of the possible occurrence of any of the events described in clauses (i) through (iii) above. See "--Risk Factors Relating to the Preferred Securities--Proposed Tax Legislation" for a discussion of certain legislative proposals that, if adopted, could give rise to a Tax Event, which may permit the Company to cause a redemption of the Preferred Securities prior to June 30, 2003.

"Capital Treatment Event" means the receipt by the Trust of an opinion of counsel experienced in such matters to the effect that, as a result of any amendment to or any change (including any announced prospective change) in the laws (or any regulations thereunder) of the United States or any political subdivision thereof or therein, or as a result of any official administrative pronouncement or judicial decision interpreting or applying such laws or regulations, which amendment or change is effective or which proposed change, pronouncement or decision is announced on or after the date of issuance of the Preferred Securities under the Trust Agreement, there is more than an insubstantial risk of impairment of the Company's ability to treat the aggregate Liquidation Amount of the Preferred Securities (or any substantial portion thereof) as "Tier 1 Capital" (or the then equivalent thereof) for purposes of the capital adequacy guidelines of the Federal Reserve, as then applicable to the Company; provided, however, that the inability of the Company to treat all or any portion of the Liquidation Amount of the Preferred Securities as Tier 1 Capital shall not constitute the basis for a Capital Treatment Event if such inability results from the Company having cumulative preferred capital in excess of the amount which may qualify for treatment as Tier 1 Capital under applicable capital adequacy guidelines of the Federal Reserve.

"Investment Company Event" means the receipt by the Trust of an opinion of counsel experienced in such matters to the effect that, as a result of the occurrence of a change in law or regulation or a change in interpretation

15

or application of law or regulation by any legislative body, court, governmental agency or regulatory authority, the Trust is or will be considered an "investment company" that is required to be registered under the Investment Company Act of 1940, as amended (the "Investment Company Act"), which change becomes effective on or after the date of original issuance of the Preferred Securities.

SHORTENING OF STATED MATURITY OF JUNIOR SUBORDINATED DEBENTURES

The Company has the right, at any time, to shorten the maturity of the Junior Subordinated Debentures to a date not earlier than June 30, 2003. The exercise of such right is subject to the Company having received prior approval of the Federal Reserve if then required under applicable capital guidelines or policies of the Federal Reserve. See "Description of the Junior Subordinated Debentures-- General."

RIGHTS UNDER THE GUARANTEE

The Guarantee guarantees to the holders of the Preferred Securities, to the extent not paid by the Trust, (i) any accrued and unpaid Distributions required to be paid on the Preferred Securities, to the extent that the Trust has funds available therefor at such time, (ii) the Redemption Price (as defined herein) with respect to any Preferred Securities called for redemption, to the extent that the Trust has funds available therefor at such time, and (iii) upon a voluntary or involuntary dissolution, winding-up or liquidation of the Trust (other than in connection with the distribution of Junior Subordinated Debentures to the holders of Preferred Securities or a redemption of all of the Preferred Securities), the lesser of (a) the amount of the Liquidation Distribution (as defined herein), to the extent the Trust has funds available therefor at such time, and (b) the amount of assets of the Trust remaining available for distribution to holders of the Preferred Securities in liquidation of the Trust. The holders of not less than a majority in Liquidation Amount of the Preferred Securities have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Guarantee Trustee in respect of the Guarantee or to direct the exercise of any trust power conferred upon the Guarantee Trustee under the Guarantee. Any holder of the Preferred Securities may institute a legal proceeding directly against the Company to enforce its rights under the Guarantee without first instituting a legal proceeding against the Trust, the Guarantee Trustee or any other Person (as defined in the Guarantee). If the Company were to default on its obligation to pay amounts payable under the Junior Subordinated Debentures, the Trust would lack funds for the payment of Distributions or amounts payable on redemption of the Preferred Securities or otherwise, and, in such event, holders of Preferred Securities would not be able to rely upon the Guarantee for such amounts. In the event, however, that a Debenture Event of Default has occurred and is continuing and such event is attributable to the failure of the Company to pay interest on or principal of the Junior Subordinated Debentures on the payment date on which such payment is due and payable, then a holder of Preferred Securities may institute a legal proceeding directly against the Company for enforcement of payment to such holder of the principal of or interest on such Junior Subordinated Debentures having a principal amount equal to the aggregate Liquidation Amount of the Preferred Securities of such holder (a "Direct Action"). The exercise by the Company of its right, as described herein, to defer the payment of interest on the Junior Subordinated Debentures does not constitute a Debenture Event of Default. In connection with such Direct Action, the Company will have a right of set-off under the Indenture to the extent of any payment made by the Company to such holder of Preferred Securities in the Direct Action. Except as described herein, holders of Preferred Securities will not be able to exercise directly any other remedy available to the holders of the Junior Subordinated Debentures or assert directly any other rights in respect of the Junior Subordinated Debentures. See "Description of the Junior Subordinated Debentures-- Enforcement of Certain Rights by Holders of Preferred Securities," "Description of the Junior Subordinated Debentures--Debenture Events of Default" and "Description of the Guarantee." The Trust Agreement provides that each holder of Preferred Securities by acceptance thereof agrees to the provisions of the Guarantee and the Indenture.

NO VOTING RIGHTS EXCEPT IN LIMITED CIRCUMSTANCES

16

Holders of Preferred Securities will have no voting rights except in limited circumstances relating only to the modification of the Preferred Securities and the exercise of the rights of the Trust as holder of the Junior Subordinated Debentures and the Guarantee. Holders of Preferred Securities will not be entitled to vote to appoint, remove or replace the Property Trustee or the Delaware Trustee, as such voting rights are vested exclusively in the holder of the Common Securities (except upon the occurrence of certain events described herein). The Property Trustee, the Administrative Trustees and the Company may amend the Trust Agreement without the consent of holders of Preferred Securities to ensure that the Trust will be classified for United States federal income tax purposes as a grantor trust even if such action adversely affects the interests of such holders. See "Description of the Preferred Securities--Voting Rights; Amendment of Trust Agreement" and "Description of the Preferred Securities--Removal of the Trust Trustees."

PROPOSED TAX LEGISLATION

In both 1996 and 1997 legislation was proposed that would, if enacted, have adversely affected the tax treatment of the Preferred Securities. On March 19, 1996, President Clinton proposed certain tax law changes (the "1996 Proposed Legislation") that would, among other things, generally deny corporate issuers a deduction for interest in respect of certain debt obligations having a maximum term in excess of 20 years and not shown as indebtedness on the issuer's applicable consolidated balance sheet. Neither the 1996 Proposed Legislation or similar legislation was enacted during the 104th Congress. On February 6, 1997, President Clinton proposed in the administration's fiscal year 1998 budget certain tax law changes (the "Administration's 1997 Tax Proposals") that would b among other things, generally deny corporate issuers a deduction for interest or OID in respect of certain debt obligations having a maximum term in excess of 15 years and not shown as indebtedness on the issuer's applicable consolidated balance sheet. Neither the Administration's 1997 Tax Proposals nor similar legislation was enacted by the 105th Congress. There can be no assurance, however, that legislation enacted after the date hereof will not adversely affect the ability of the Company to deduct the interest payable on the Junior Subordinated Debentures or otherwise give rise to a Tax Event.

REDEMPTION; EXCHANGE OF PREFERRED SECURITIES FOR JUNIOR SUBORDINATED DEBENTURES

The Company has the right at any time to dissolve the Trust and cause the Junior Subordinated Debentures, after satisfaction of liabilities to creditors of the Trust, to be distributed to the holders of the Preferred Securities in exchange therefor in liquidation of the Trust. The exercise of such right is subject to the Company having received prior approval of the Federal Reserve if then required under applicable capital guidelines or policies of the Federal Reserve. The Company will have the right, in certain circumstances, to redeem the Junior Subordinated Debentures in whole or in part, in lieu of a distribution of the Junior Subordinated Debentures by the Trust, in which event the Trust will redeem the Trust Securities on a pro rata basis to the same extent as the Junior Subordinated Debentures are redeemed by the Company. Any such distribution or redemption prior to the Stated Maturity will be subject to prior approval of the Federal Reserve if then required under applicable capital guidelines or policies of the Federal Reserve. See "Description of the Preferred Securities--Redemption or Exchange--Tax Event Redemption, Capital Treatment Event Redemption or Investment Company Event Redemption."

Under current United States federal income tax law, a distribution of Junior Subordinated Debentures upon the dissolution of the Trust would not be a taxable event to holders of the Preferred Securities. If, however, the Trust is characterized as an association taxable as a corporation at the time of the dissolution of the Trust, the distribution of the Junior Subordinated Debentures may constitute a taxable event to holders of Preferred Securities. Moreover, upon occurrence of a Tax Event, a dissolution of the Trust in which holders of the Preferred Securities receive cash may be a taxable event to such holders. See "Certain Federal Income Tax Consequences--Receipt of Junior Subordinated Debentures or Cash Upon Liquidation of the Trust."

There can be no assurance as to the market prices for the Preferred Securities or the Junior Subordinated Debentures that may be distributed in exchange for Preferred Securities upon a dissolution or liquidation of the Trust. The Preferred Securities or the Junior Subordinated Debentures may trade at a discount to the price that the investor paid to purchase the Preferred Securities offered hereby. Because holders of Preferred Securities may receive Junior Subordinated Debentures, prospective purchasers of Preferred Securities are also making an investment decision with regard to the Junior Subordinated Debentures and should carefully review all the information regarding the Junior Subordinated Debentures contained herein.

If the Junior Subordinated Debentures are distributed to the holders of Preferred Securities upon the liquidation of the Trust, the Company will use its best efforts to list the Junior Subordinated Debentures on The Nasdaq Stock Market's National Market or such stock exchanges, if any, on which the Preferred Securities are then listed.

LIMITED COVENANTS

The covenants in the Indenture are limited, and there are no covenants relating to the Company in the Trust Agreement. As a result, neither the Indenture nor the Trust Agreement protects holders of Junior Subordinated Debentures, or Preferred Securities, respectively, in the event of a material adverse change in the Company's financial condition or results of operations or limits the ability of the Company or any subsidiary to incur additional indebtedness. Therefore, the provisions of these governing instruments should not be considered a significant factor in evaluating whether the Company will be able to comply with its obligations under the Junior Subordinated Debentures or the Guarantee.

TRADING PRICE; ABSENCE OF PRIOR PUBLIC MARKET FOR THE PREFERRED SECURITIES

The Preferred Securities may trade at a price that does not accurately reflect the value of accrued but unpaid interest (or OID if the Junior Subordinated Debentures are treated as having been issued, or reissued, with OID) with respect to the underlying Junior Subordinated Debentures. A holder who disposes of his Preferred Securities will be required to include in ordinary income (i) any portion of the amount realized that is attributable to such accrued but unpaid interest to the extent not previously included in income, or
(ii) any amount of OID, in either case, that has accrued on his pro rata share of the underlying Junior Subordinated Debentures during the taxable year of sale through the date of disposition. Any such income inclusion will increase the holder's adjusted tax basis in his Preferred Securities disposed of. To the extent that the amount realized in the sale is less than the holder's adjusted tax basis, a holder will recognize a capital loss. Subject to certain limited exceptions, capital losses cannot be applied to offset ordinary income for United States federal income tax purposes. See "Certain Federal Income Tax Consequences - Disposition of Preferred Securities."

There is no current public market for the Preferred Securities. Although application has been made to have the Preferred Securities approved for quotation on The Nasdaq Stock Market's National Market, there can be no assurance that an active public market will develop for the Preferred Securities or that, if such market develops, the market price will equal or exceed the public offering price set forth on the cover page of this Prospectus. The public offering price for the Preferred Securities has been determined through negotiations between the Company and the Underwriters. Prices for the Preferred Securities will be determined in the marketplace and may be influenced by many factors, including prevailing interest rates, the liquidity of the market for the Preferred Securities, investor perceptions of the Company and general industry and economic conditions.

POSSIBLE ADVERSE EFFECT ON MARKET PRICES

There can be no assurance as to the market prices for the Preferred Securities or the Junior Subordinated Debentures that may be distributed in exchange for Preferred Securities if a termination of the Trust were to occur. Accordingly, the Preferred Securities or the Junior Subordinated Debentures may trade at a discount from the price

18

that investors paid to purchase the Preferred Securities offered hereby. Because holders of Preferred Securities may receive Junior Subordinated Debentures in liquidation of the Trust and because Distributions are otherwise limited to payments on the Junior Subordinated Debentures, prospective purchasers of the Preferred Securities are also making an investment decision with regard to the Junior Subordinated Debentures and should carefully review all the information regarding the Junior Subordinated Debentures contained herein. See "Description of Junior Subordinated Debentures."

PREFERRED SECURITIES ARE NOT INSURED

The Preferred Securities are not insured by the Bank Insurance Fund (the "BIF") or the Savings Association Insurance Fund (the "SAIF") of the Federal Deposit Insurance Corporation (the "FDIC") or by any other governmental agency.

RISK FACTORS RELATING TO THE COMPANY

LENDING RISKS -- CREDIT QUALITY

A central focus of the Company's and the Bank's strategy is the continued development and growth of a diversified loan portfolio, with emphasis on commercial real estate, residential real estate and commercial and industrial loans. Certain risks are inherent in the lending function, including a borrower's inability to pay, insufficient collateral coverage and changes in interest rates. Repayment risk on commercial loans is significantly affected by changing economic conditions in a particular geographical area, business or industry which could impair future operating performance. Risks associated with real estate loans and general business loans include changes in general economic conditions which may affect the borrower's ability to repay as well as underlying collateral values. Installment and other consumer loans are subject to repayment risk.

Multi-family residential and commercial real estate loans are generally viewed in the banking community as exposing the lender to greater credit risk than 1-4 family residential real estate loans and typically involve higher loan principal amounts. At December 31, 1997, the Bank's multi-family residential and commercial real estate portfolios totaled $ 140.3 million, or 44.3% of total loans and loans held for sale. Of this amount, $29.6 million, or 21.1% consisted of multi-family residential real estate loans and $110.7 million, or 78.9%, consisted of commercial real estate loans.

The Bank currently originates loans secured by commercial real estate properties. The Bank attempts to offset the risks associated with commercial real estate lending by primarily lending to individuals who have proven management experience and who will be actively involved in the management of the property, and by making such loans with lower loan-to-value ratios than 1-4 family residential real estate loans. Economic events and government regulations, which are outside the control of the borrower or lender, could affect the value of the security for such loans or the future cash flow of the affected properties.

At December 31, 1997, the Bank had $1,831,000 in non-performing commercial real estate loans and $19,000 in non-performing multi-family residential real estate loans. For the year ended December 31, 1997, the Bank experienced charge-offs of $48,000 and $0 on commercial real estate loans and multi-family residential real estate loans, respectively.

At December 31, 1997, 24.1% of the Bank's total loans and loans held for sale were secured by 1-4 family residential mortgages, of which 74% were adjustable rate mortgages ("ARMs"). Generally, ARMs pose credit risks different from the risks inherent in fixed-rate loans because when interest rates rise the borrower's payments

19

rise, thereby increasing the potential for default. However, long-term fixed-rate loans expose the Bank to higher interest-rate risk.

At December 31, 1997, 16.0% of the Bank's total loans were commercial and industrial. Commercial and industrial loans are typically lines of credit against which the borrowers may draw from time to time to meet cash needs. The amount available to any customer may be fixed by agreement or may be determined by a formula based on the borrower's current inventory or accounts receivable or similar criteria. Interest rates typically float with reference to a prime or base rate establish by the Bank from time to time. Therefore, in addition to the risk of the borrower's credit, some commercial or industrial loans may become unprofitable or less profitable if the reference interest rates decline.

COMPETITION

The Bank faces significant competition both in generating loans and in attracting deposits. The eastern Massachusetts area is a highly competitive market. The Bank faces direct competition from a significant number of financial institutions operating in its market area, many with a state-wide or regional presence and, in some cases, a national presence. Many of these financial institutions are significantly larger and have greater financial resources than the Bank. The Bank's competition for loans comes principally from commercial banks, savings banks, mortgage banking companies, credit unions and insurance companies. The Bank faces competition for deposits from savings and commercial banks and credit unions. In addition, the Bank faces increasing competition for deposits from non-bank institutions such as brokerage firms and insurance companies in such instruments as short-term money market funds, corporate and government securities funds, mutual funds and annuities. Competition may also increase as a result of the lifting of restrictions on the interstate operations of financial institutions.

SENSITIVITY TO LOCAL ECONOMY

Prevailing economic conditions, as well as government policies and regulations concerning, among other things, monetary and fiscal affairs, significantly affect the operations of financial institutions such as the Bank. The New England region of the United States, including eastern Massachusetts (the Bank's primary market area), experienced a significant economic decline which began in 1988 and outlasted the national recession. This decline adversely affected employment, the real estate markets and the banking industry in the Bank's market area. Any deterioration of economic conditions or real estate markets in the Bank's market area could adversely affect the financial condition and results of operations of the Bank in the future.

ECONOMIC CONDITIONS AND MONETARY POLICIES

Conditions beyond the Company's control may have a significant impact on changes in net interest income from one period to another. Examples of such conditions could include: (i) the strength of credit demands by customers; (ii) fiscal and debt management policies of the federal government, including changes in tax laws; (iii) the Federal Reserve's monetary policy, including the percentage of deposits that must be held in the form of non-earning cash reserves; (iv) the introduction and growth of new investment instruments and transaction accounts by non-bank financial competitors; and (v) changes in rules and regulations governing the payment of interest on deposit accounts.

SENSITIVITY TO FLUCTUATIONS IN INTEREST RATES

The Company's profitability, like that of most similarly situated financial institutions, is dependent to a large extent upon the Bank's net interest income, which is the difference between its interest income on interest-earning assets, such as loans and investments, and its interest expense on interest-bearing liabilities, such as deposits and borrowings. Accordingly, the Company's results of operations and financial condition are largely dependent on

20

movements in market interest rates and its ability to manage its assets in response to such movements. The difference between the amount of the total interest-earning assets and interest-bearing liabilities which reprice within a given time period could have a negative effect on the Bank's net interest income depending on whether such difference was positive or negative and the direction of movement of interest rates.

Increases in interest rates may reduce demand for loans and, thus, the amount of loan and commitment fees. In addition, fluctuations in interest rates may also result in disintermediation, which is the flow of funds away from depository institutions into direct investments which pay a higher rate of return, and may affect the value of the Company's investment securities and other interest earning assets. Given that the Bank's assets consist of a substantial number of loans with interest rates which change in accordance with changes in prevailing market rates, if interest rates rise sharply, many of the Bank's borrowers would be required to make higher interest payments on their loans. Thus, increases in interest rates may cause the Bank to experience an increase in delinquent loans and defaults to the extent that borrowers are unable to meet their increased debt servicing obligations.

ALLOWANCE FOR LOAN LOSSES

The Bank has established an allowance for loan losses in accordance with generally accepted accounting principles. The Company believes that the allowance is adequate. Nevertheless, future additions to the allowance in the form of the provision for loan losses may be necessary due to changes in economic conditions and growth of the Bank's loan portfolio. In addition, various regulatory agencies, as an integral part of their examination process, periodically review the Bank's allowance for loan losses. An increase in the Bank's provision for loan losses would negatively affect the Company's earnings.

LEGISLATIVE AND REGULATORY DEVELOPMENTS

The financial institutions industry is subject to significant regulation which has materially affected the financial institutions industry in the past and will do so in the future. Such regulations, which affect the Company on a daily basis, may be changed at any time, and the interpretation of the relevant law and regulations are also subject to change by the authorities who examine the Company and the Bank and interpret those laws and regulations. There can be no assurance that any present or future changes in the laws or regulations or in their interpretation will not adversely and materially affect the Company.

POTENTIAL LIABILITY FOR UNDERCAPITALIZED SUBSIDIARY BANK

Under federal law, a bank holding company may be required to guarantee a capital plan filed by an undercapitalized bank or thrift subsidiary with its primary regulator. If the subsidiary defaults under the plan, the holding company may be required to contribute to the capital of the subsidiary bank an amount equal to the lesser of 5% of the bank's assets at the time it became undercapitalized or the amount necessary to bring the bank into compliance with applicable capital standards. It is, therefore, possible that the Company would be required to contribute capital to the Bank or any other bank it may acquire in the event that the Bank or such other bank becomes undercapitalized.

YEAR 2000 COMPLIANCE

During 1997 the Company conducted a comprehensive review of its computer systems to identify the systems that could be affected by the "Year 2000" issue and has developed an implementation plan to resolve the issue. The Year 2000 problem is the result of computer programs being written using two digits rather than four to define the applicable year. Any of the Company's programs that have time-sensitive software may recognize a date ending in "00" as the year 1900 rather than the year 2000. The result might be miscalculations or a major system failure. The Company plans to convert to a new core processing software and implement modifications to existing software beginning mid-1998. The Company's audit committee is also the Year 2000 compliance committee and reports to the board of directors of the Company. The Company believes that the Year 2000 problem will not pose

21

significant operational problems for the Company's computer systems as so modified and converted. The new core processing software is designed to be Year 2000 compliant and the modifications currently planned for the Company's other systems do not involve material cost to the Company. However, if such modifications and conversions are not completed in a timely manner, the Year 2000 problem may have a material adverse impact on the operations of the Company.

STRATEGY

The Company has sought to consistently increase earnings per share and to maximize return on equity through a combination of strategies, including:

o Personalized Service. The Company seeks to offer a full range of products and services to its customers while maintaining the high level of personalized service associated with a community bank. Strong, long-term relationships are a cornerstone of this strategy. The Company strives to respond quickly to customer needs and provides customers with direct access to senior lending officers with approval authority. The Company intends to use its community-based position to build its portfolio of commercial loans to small and medium-sized businesses.

o Growth through Strategic Acquisitions. The Company is in the process of completing the acquisition of Haymarket Cooperative Bank. See "Recent Developments" below. The Company continues to seek suitable strategic opportunities for consolidation and expansion of its market position through selective acquisitions.

22

RECENT DEVELOPMENTS

On December 10, 1997, the Company announced an agreement to acquire Haymarket Cooperative Bank. Haymarket, located in Boston, Massachusetts, has approximately $142 million of assets and will be acquired for approximately $20 million in cash. The Haymarket acquisition will add two branch locations in Boston's financial district, allowing the Company to provide commercial banking services to a greater number of Boston's small and medium-sized businesses. The acquisition will also connect the Bank geographically, giving it a market presence from Beverly on the North Shore of Massachusetts to Quincy and Braintree on the South Shore. The transaction is subject to federal and state regulatory approvals.

On April 14, 1998, the Company announced net income of $1,802,000 or $0.31 per share for the first quarter of 1998, compared to net income of $1,376,000, or $0.24 per share for the first quarter of 1997.

Total stockholders' equity was $55.3 million at March 31, 1998, compared to $48.4 million at March 31, 1997. The Company's leverage ratio at March 31, 1998, stood at 9.05%, compared to a leverage ratio of 8.62% on March 31, 1997. Book value at March 31, 1998 was $9.55 per share.

The Company's allowance for loan losses was $4.7 million, or 1.46% of loans outstanding at the end of the first quarter, compared to $4.3 million, or 1.46% of loans outstanding at March 31, 1997. Non-accruing loans totaled $1.5 million at March 31, 1998, compared to $1.7 million at the end of the previous quarter.

The Company's Board of Directors voted a regular quarterly dividend of 5 cents ($0.05) per share on the Company's Class A common stock, and 0.70 cents ($0.0070) per share on the Company's Class B common stock. The dividends were declared payable May 15, 1998 to stockholders of record on May 1, 1998.

The principal executive office of the Company is located at 400 Mystic Avenue, Medford, Massachusetts 02155 and its telephone number is (781) 391-4000.

CENTURY BANCORP CAPITAL TRUST

The Trust is a statutory business trust formed under Delaware law pursuant to (i) a trust agreement, dated as of April 21, 1998, executed by the Company, as depositor, and the trustees of the Trust and (ii) a certificate of trust filed with the Secretary of State of the State of Delaware on April 21, 1998. The initial trust agreement will be amended and restated in its entirety (as so amended and restated, the "Trust Agreement") substantially in the form filed as an exhibit to the Registration Statement of which this Prospectus forms a part. The Trust Agreement will be qualified as an indenture under the Trust Indenture Act. Upon issuance of the Preferred Securities, the purchasers thereof will own all of the Preferred Securities. The Company will acquire all of the Common Securities, which will represent an aggregate liquidation amount equal to at least 3% of the total capital of the Trust. The Common Securities will rank pari passu, and payments will be made thereon pro rata, with the Preferred Securities, except that upon the occurrence and during the continuance of an Event of Default (as defined herein) under the Trust Agreement resulting from a Debenture Event of Default, the rights of the Company as holder of the Common Securities to payment in respect of Distributions and payments upon liquidation, redemption or otherwise will be subordinated to the rights of the holders of the Preferred Securities. See "Description of the Preferred Securities--Subordination of Common Securities." The Trust exists for the exclusive purposes of (i) issuing the Trust Securities representing undivided beneficial interests in the assets of the Trust, (ii) investing the gross proceeds of the Trust Securities in the Junior Subordinated Debentures issued by the Company, and (iii) engaging in only those other activities necessary, advisable, or incidental thereto. The Junior Subordinated Debentures and payments thereunder will be the only assets of the Trust and payments under the Junior Subordinated Debentures will be the only revenue of the Trust. The Trust has a term of 55 years, but may dissolve earlier as provided in the Trust Agreement. The principal executive office of the Trust is c/o Century Bancorp, Inc., 400 Mystic Avenue, Medford, Massachusetts 02155, and its telephone number is (781) 391-4000.

The number of Trustees will, pursuant to the Trust Agreement, initially be five. Three of the Trustees (the "Administrative Trustees") will be persons who are employees or officers of, or who are affiliated with, the Company. The fourth trustee will be a financial institution that is unaffiliated with the Company, which trustee will serve as institutional trustee under the Trust Agreement and as indenture trustee for the purposes of compliance with the provisions of the Trust Indenture Act (the "Property Trustee"). State Street Bank and Trust Company, a state chartered trust company organized under the laws of The Commonwealth of Massachusetts, will be the Property Trustee until removed or replaced by the holder of the Common Securities. For purposes of compliance with the provisions of the Trust Indenture Act, State Street Bank and Trust Company, a state chartered trust company organized under the laws of The Commonwealth of Massachusetts, will also act as trustee (the "Guarantee Trustee") under the Guarantee and as Debenture Trustee (as defined herein) under the Indenture. The fifth trustee will be an entity that maintains its principal place of business in the State of Delaware (the "Delaware Trustee"). Wilmington Trust Company, a Delaware banking corporation, will act as Delaware Trustee.

23

The Property Trustee will hold title to the Junior Subordinated Debentures for the benefit of the holders of the Trust Securities and in such capacity will have the power to exercise all rights, powers and privileges under the Indenture. The Property Trustee will also maintain exclusive control of a segregated non-interest-bearing bank account (the "Property Account") to hold all payments made in respect of the Junior Subordinated Debentures for the benefit of the holders of the Trust Securities. The Property Trustee will make payments of Distributions and payments on liquidation, redemption and otherwise to the holders of the Trust Securities out of funds from the Property Account. The Guarantee Trustee will hold the Guarantee for the benefit of the holders of the Preferred Securities. The Company, as the holder of all the Common Securities, will have the right to appoint, remove or replace any Trustee and to increase or decrease the number of Trustees. The Company will pay all fees and expenses related to the Trust and the offering of the Trust Securities.

The rights of the holders of the Preferred Securities, including economic rights, rights to information and voting rights, are set forth in the Trust Agreement, the Delaware Business Trust Act (the "Trust Act") and the Trust Indenture Act. See "Description of the Preferred Securities."

24

USE OF PROCEEDS

The Trust will use the gross proceeds from the sale of the Preferred Securities to purchase Junior Subordinated Debentures of the Company. The Company intends to use the net proceeds of the sale of the Junior Subordinated Debentures for general corporate purposes, including contributions to the Bank to fund its operations, the financing of one or more future acquisitions by the Company if and when suitable opportunities arise and the repurchase of outstanding equity securities of the Company. Initially, the net proceeds may be used to make investments in short-term investment securities pending its use for the purposes described above.

The Federal Reserve has approved, subject to certain limitations as to amount, the use of certain cumulative preferred stock instruments such as the Preferred Securities as Tier 1 capital for bank holding companies such as the Company. The Company has elected to issue the Preferred Securities because the Company expects the Preferred Securities to qualify as Tier 1 capital and the Distributions payable on the Preferred Securities to be a tax deductible expense of the Company. The Company expects that, upon completion of the sale of the Preferred Securities offered hereby, Preferred Securities having an aggregate Liquidation Amount of approximately $17.6 million at December 31, 1997 will be eligible to qualify as Tier 1 capital under the capital guidelines of the Federal Reserve. Preferred Securities representing an aggregate Liquidation Amount in excess of that amount are expected to be treated as Tier 2 capital until all or some of that excess is eligible to qualify as Tier 1 capital under the capital guidelines of the Federal Reserve.

25

MARKET FOR THE PREFERRED SECURITIES

Application has been made to have the Preferred Securities approved for quotation on The Nasdaq Stock Market's National Market under the symbol "CNBKP." Although the Underwriters have informed the Company that they currently intend to make a market in the Preferred Securities, there can be no assurance that an active and liquid trading market will develop, or, if developed, that such a market will continue. The offering price and distribution rate have been determined by negotiations among representatives of the Company and the Underwriters, and the offering price of the Preferred Securities may not be indicative of the market price following the offering. See "Underwriting."

ACCOUNTING TREATMENT

The Trust will be treated, for financial reporting purposes, as a subsidiary of the Company and, accordingly, the accounts of the Trust will be included in the consolidated financial statements of the Company. The Preferred Securities will be presented as a separate category of long-term debt in the consolidated balance sheet of the Company under the caption "Guaranteed Preferred Beneficial Interests in the Company's Junior Subordinated Debentures," and appropriate disclosures about the Preferred Securities, the Guarantee and the Junior Subordinated Debentures will be included in the notes to consolidated financial statements. The Company will record Distributions payable on the Preferred Securities as interest expense in the consolidated statements of income for financial reporting purposes.

All future reports of the Company filed under the Exchange Act will (a) present the Trust Securities issued by the Trust on the balance sheet as a separate category of long-term debt item entitled "Guaranteed preferred beneficial interests in the Company's junior subordinated debentures," (b) include in a footnote to the financial statements disclosure that the sole assets of the Trust are the Junior Subordinated Debentures (including the outstanding principal amount, interest rate and maturity date of such Junior Subordinated Debentures), and (c) include in an audited footnote to the financial statements disclosure that the Company owns all the Common Securities of the Trust, and that the back-up obligations, in the aggregate, constitute a full and unconditional guarantee by the Company of the obligations of the Trust under the Preferred Securities.

CAPITALIZATION

The following table sets forth (i) the consolidated capitalization of the Company at December 31, 1997 and (ii) the consolidated capitalization of the Company giving effect to the issuance of the Preferred Securities hereby offered by the Trust and receipt by the Company of the net proceeds from the corresponding sale of the Junior Subordinated Debentures to the Trust, as if the sale of the Preferred Securities had been consummated on December 31, 1997 and assuming the Underwriters' over-allotment option was not exercised.

(1) In connection with the issuance of the guaranteed preferred beneficial interests in the Company's Junior Subordinated Debentures, the Company estimates it will incur expenses of $________ (including Underwriters' compensation of $________). The Junior Subordinated Debentures will mature on June 30, 2029, which date may be shortened to a date not earlier than June 30, 2003 if certain conditions are met.
(2) The leverage ratio is Tier 1 capital divided by average quarterly assets, after deducting intangible assets and net deferred tax assets in excess of regulatory maximum limits.
(3) The capital ratios, as adjusted, are computed including the total estimated net proceeds from the sale of the Preferred Securities, in a manner consistent with Federal Reserve guidelines.
(4) Federal Reserve guidelines for calculation of Tier 1 capital to risk-weighted assets limit the amount of cumulative preferred stock and securities similar to the Preferred Securities which can be included in Tier 1 capital to 25% of other Tier 1 capital. The risk-based capital ratio assumes net proceeds are invested in assets that carry a 20% risk-weighting.

DESCRIPTION OF THE PREFERRED SECURITIES

The Preferred Securities will be issued pursuant to the terms of the Trust Agreement. The Trust Agreement will be qualified as an indenture under the Trust Indenture Act. The Property Trustee, State Street Bank and Trust Company, will act as indenture trustee for the Preferred Securities under the Trust Agreement for purposes of complying with the provisions of the Trust Indenture Act. The terms of the Preferred Securities will include those stated in the Trust Agreement and those made part of the Trust Agreement by the Trust Indenture Act. The following summary of the material terms and provisions of the Preferred Securities and the Trust Agreement does not purport to be complete and is subject to, and is qualified in its entirety by reference to, the Trust Agreement, the Trust Act and the Trust Indenture Act. Wherever particular defined terms of the Trust Agreement are referred to, but not defined herein, such defined terms are incorporated herein by reference. The form of the Trust Agreement has been filed as an exhibit to the Registration Statement of which this Prospectus forms a part.

GENERAL

Pursuant to the terms of the Trust Agreement, the Trustees, on behalf of the Trust, will issue the Trust Securities. All of the Common Securities will be owned by the Company. The Preferred Securities will represent preferred undivided beneficial interests in the assets of the Trust and the holders thereof will be entitled to a preference over the Common Securities in certain circumstances with respect to Distributions and amounts payable on redemption or liquidation, as well as other benefits as described in the Trust Agreement. The Trust Agreement does not permit the issuance by the Trust of any securities other than the Trust Securities or the incurrence of any indebtedness by the Trust.

The Preferred Securities will rank pari passu, and payments will be made thereon pro rata with the Common Securities, except as described under "--Subordination of Common Securities." Legal title to the Junior Subordinated Debentures will be held by the Property Trustee in trust for the benefit of the holders of the Trust Securities. The Guarantee executed by the Company for the benefit of the holders of the Preferred Securities will be a guarantee on a subordinated basis with respect to the Preferred Securities, but will not guarantee payment of Distributions or amounts payable on redemption or liquidation of such Preferred Securities when the Trust does not have funds on hand available to make such payments. State Street Bank and Trust Company, as Guarantee Trustee, will hold the Guarantee for the benefit of the holders of the Preferred Securities. See "Description of the Guarantee."

DISTRIBUTIONS

Payment of Distributions. Distributions on each Preferred Security will be payable at the annual rate of ___% of the stated Liquidation Amount of $10, payable quarterly in arrears on March 31, June 30, September 30 and December 31 of each year, to the holders of the Preferred Securities on the relevant record dates (each date on which Distributions are payable in accordance with the foregoing, a "Distribution Date"). The record date will be the fifteenth day of the month in which the relevant Distribution Date occurs. Distributions will accumulate from May __, 1998, the date of original issuance. The first Distribution Date for the Preferred Securities will be September 30, 1998. The amount of Distributions payable for any period will be computed on the basis of a 360- day year of twelve 30-day months. In the event that any date on which Distributions are payable on the Preferred Securities is not a Business Day, then payment of the Distributions payable on such date will be made on the next succeeding day that is a Business Day (and without any additional Distributions, interest or other payment in respect of any such delay) with the same force and effect as if made on the date such payment was originally due and payable. "Business Day" means any day other than a Saturday or a Sunday, a day on which banking institutions in the City of Boston are authorized or required by law or executive order to remain closed or a day on which the corporate trust office of the Property Trustee or the Debenture Trustee is closed for business.

28

Extension Period. The Company has the right under the Indenture, so long as no Debenture Event of Default has occurred and is continuing, to defer the payment of interest on the Junior Subordinated Debentures at any time, or from time to time (each, an "Extension Period"), which, if exercised, would defer quarterly Distributions on the Preferred Securities during any such Extension Period. Distributions to which holders of the Preferred Securities are entitled will accumulate additional Distributions thereon at the rate per annum of _________ % thereof, compounded quarterly from the relevant Distribution Date. "Distributions," as used herein, includes any such additional Distributions. The right to defer the payment of interest on the Junior Subordinated Debentures is limited, however, to a period, in each instance, not exceeding 20 consecutive quarters and no Extension Period may extend beyond the Stated Maturity of the Junior Subordinated Debentures. During any such Extension Period, the Company may not (i) declare or pay any dividends or distributions on, or redeem, purchase, acquire or make a liquidation payment with respect to, any of the Company's capital stock, (ii) make any payment of principal, interest or premium, if any, on or repay, repurchase or redeem any debt securities of the Company that rank pari passu with or junior in interest to the Junior Subordinated Debentures or make any guarantee payments with respect to any guarantee by the Company of the debt securities of any subsidiary of the Company if such guarantee ranks pari passu with or junior in interest to the Junior Subordinated Debentures (other than payments under the Guarantee), or (iii) redeem, purchase or acquire less than all of the Junior Subordinated Debentures or any of the Preferred Securities. Prior to the termination of any such Extension Period, the Company may further defer the payment of interest; provided, that such Extension Period may not exceed 20 consecutive quarters or extend beyond the Stated Maturity of the Junior Subordinated Debentures. Upon the termination of any such Extension Period and the payment of all amounts then due, the Company may elect to begin a new Extension Period, subject to the above requirements. Subject to the foregoing, there is no limitation on the number of times that the Company may elect to begin an Extension Period.

The Company has no current intention of exercising its right to defer payments of interest by extending the interest payment period on the Junior Subordinated Debentures.

Source of Distributions. The funds of the Trust available for distribution to holders of its Preferred Securities will be limited to payments under the Junior Subordinated Debentures in which the Trust will invest the proceeds from the issuance and sale of its Trust Securities. See "Description of the Junior Subordinated Debentures." Distributions will be paid through the Property Trustee who will hold amounts received in respect of the Junior Subordinated Debentures in the Property Account for the benefit of the holders of the Trust Securities. If the Company does not make interest payments on the Junior Subordinated Debentures, the Property Trustee will not have funds available to pay Distributions on the Preferred Securities. The payment of Distributions (if and to the extent the Trust has funds legally available for the payment of such Distributions and cash sufficient to make such payments) is guaranteed by the Company. See "Description of the Guarantee."

REDEMPTION OR EXCHANGE

General. The Junior Subordinated Debentures will mature on June 30, 2029. The Company will have the right to redeem the Junior Subordinated Debentures (i) on or after June 30, 2003, in whole at any time or in part from time to time, or (ii) at any time, in whole (but not in part), within 180 days following the occurrence of a Tax Event, a Capital Treatment Event or an Investment Company Event, in each case subject to receipt of prior approval by the Federal Reserve if then required under applicable capital guidelines or policies of the Federal Reserve. The Company will not have the right to purchase the Junior Subordinated Debentures, in whole or in part, from the Trust until after June 30, 2003. See "Description of the Junior Subordinated Debentures--General."

Mandatory Redemption. Upon the repayment or redemption, in whole or in part, of any Junior Subordinated Debentures, whether at Stated Maturity or upon earlier redemption as provided in the Indenture, the proceeds from such repayment or redemption will be applied by the Property Trustee to redeem a Like Amount (as defined herein) of the Trust Securities, upon not less than 30 nor more than 60 days notice, at a redemption price (the "Redemption Price") equal to the aggregate Liquidation Amount of such Trust Securities plus

29

accumulated but unpaid Distributions thereon to the date of redemption (the "Redemption Date"). See "Description of the Junior Subordinated Debentures--Redemption or Exchange." If less than all of the Junior Subordinated Debentures are to be repaid or redeemed on a Redemption Date, then the proceeds from such repayment or redemption will be allocated to the redemption of the Trust Securities pro rata.

Distribution of Junior Subordinated Debentures. Subject to the Company having received prior approval of the Federal Reserve if so required under applicable capital guidelines or policies of the Federal Reserve, the Company will have the right at any time to dissolve the Trust and, after satisfaction of the liabilities of creditors of the Trust as provided by applicable law, cause the Junior Subordinated Debentures to be distributed to the holders of Trust Securities in liquidation of the Trust. See "--Liquidation Distribution Upon Dissolution."

Tax Event Redemption, Capital Treatment Event Redemption or Investment Company Event Redemption. If a Tax Event, a Capital Treatment Event or an Investment Company Event in respect of the Trust Securities occurs and is continuing, the Company has the right to redeem the Junior Subordinated Debentures in whole (but not in part) and thereby cause a mandatory redemption of such Trust Securities in whole (but not in part) at the Redemption Price within 180 days following the occurrence of such Tax Event, Capital Treatment Event or Investment Company Event. In the event a Tax Event, a Capital Treatment Event or an Investment Company Event has occurred with respect to the Trust Securities and the Company does not elect to redeem the Junior Subordinated Debentures and thereby cause a mandatory redemption of such Trust Securities or to liquidate the Trust and cause the Junior Subordinated Debentures to be distributed to holders of such Trust Securities in liquidation of the Trust as described below under "--Liquidation Distribution Upon Dissolution," such Preferred Securities will remain outstanding and Additional Interest (as defined herein) may be payable on the Junior Subordinated Debentures. "Additional Interest" means the additional amounts as may be necessary in order that the amount of Distributions then due and payable by the Trust on the outstanding Trust Securities will not be reduced as a result of any additional taxes, duties and other governmental charges to which the Trust has become subject as a result of a Tax Event.

"Like Amount" means (i) with respect to a redemption of Trust Securities, Trust Securities having a Liquidation Amount equal to that portion of the principal amount of Junior Subordinated Debentures to be contemporaneously redeemed in accordance with the Indenture, which will be used to pay the Redemption Price of such Trust Securities, and (ii) with respect to a distribution of Junior Subordinated Debentures to holders of Trust Securities in connection with a dissolution or liquidation of the Trust, Junior Subordinated Debentures having a principal amount equal to the Liquidation Amount of the Trust Securities of the holder to whom such Junior Subordinated Debentures are distributed. Each Junior Subordinated Debenture distributed pursuant to clause
(ii) above will carry with it accumulated interest in an amount equal to the accumulated and unpaid interest then due on such Junior Subordinated Debenture.

"Liquidation Amount" means the stated amount of $10 per Trust Security.

After the liquidation date fixed for any distribution of Junior Subordinated Debentures for Preferred Securities (i) such Preferred Securities will no longer be deemed to be outstanding, and (ii) any certificates representing Preferred Securities will be deemed to represent the Junior Subordinated Debentures having a principal amount equal to the Liquidation Amount of such Preferred Securities, and bearing accrued and unpaid interest in an amount equal to the accrued and unpaid Distributions on the Preferred Securities until such certificates are presented to the Administrative Trustees or their agent for transfer or reissuance.

There can be no assurance as to the market prices for the Preferred Securities or the Junior Subordinated Debentures that may be distributed in exchange for Preferred Securities if a dissolution and liquidation of the Trust were to occur. The Preferred Securities that an investor may purchase, or the Junior Subordinated Debentures that an investor may receive on dissolution and liquidation of the Trust, may, therefore, trade at a discount to the price that the investor paid to purchase the Preferred Securities offered hereby.

30

REDEMPTION PROCEDURES

Preferred Securities redeemed on each Redemption Date will be redeemed at the Redemption Price with the applicable proceeds from the contemporaneous redemption of the Junior Subordinated Debentures. Redemptions of the Preferred Securities will be made and the Redemption Price will be payable on each Redemption Date only to the extent that the Trust has funds on hand available for the payment of such Redemption Price. See "--Subordination of the Common Securities."

If the Trust gives a notice of redemption in respect of its Preferred Securities, then, by 12:00 noon, New York time, on the Redemption Date, to the extent funds are available, the Property Trustee will irrevocably deposit with the paying agent for the Preferred Securities funds sufficient to pay the aggregate Redemption Price and will give the paying agent for the Preferred Securities irrevocable instructions and authority to pay the Redemption Price to the holders thereof upon surrender of their certificates evidencing such Preferred Securities. Notwithstanding the foregoing, Distributions payable on or prior to the Redemption Date for any Preferred Securities called for redemption will be payable to the holders of such Preferred Securities on the relevant record dates for the related Distribution Dates. If notice of redemption will have been given and funds deposited as required, then upon the date of such deposit, all rights of the holders of such Preferred Securities so called for redemption will cease, except the right of the holders of such Preferred Securities to receive the Redemption Price and any Distribution payable on or before the Redemption Date, but without interest on such Redemption Price or Distribution, and such Preferred Securities will cease to be outstanding. In the event that any date fixed for redemption of Preferred Securities is not a Business Day, then payment of the Redemption Price payable on such date will be made on the next succeeding day which is a Business Day (and without any additional Distribution, interest or other payment in respect of any such delay) with the same force and effect as if made on such date. In the event that payment of the Redemption Price in respect of Preferred Securities called for redemption is improperly withheld or refused and not paid either by the Trust, or by the Company pursuant to the Guarantee, Distributions on such Preferred Securities will continue to accrue at the then applicable rate, from the Redemption Date originally established by the Trust for such Preferred Securities to the date such Redemption Price is actually paid, in which case the actual payment date will be considered the date fixed for redemption for purposes of calculating the Redemption Price. See "Description of the Guarantee."

Subject to applicable law (including, without limitation, United States federal securities law), and further provided that the Company does not and is not continuing to exercise its right to defer interest payments on the Junior Subordinated Debentures, the Company or its subsidiaries may at any time and from time to time purchase outstanding Preferred Securities by tender, in the open market or by private agreement.

Payment of the Redemption Price on the Preferred Securities and any distribution of Junior Subordinated Debentures to holders of Preferred Securities will be made to the applicable holders thereof as they appear on the register for the Preferred Securities on the relevant record date, which date will be the date 15 days prior to the Redemption Date or liquidation date, as applicable.

If less than all of the Trust Securities are to be redeemed on a Redemption Date, then the aggregate Liquidation Amount of such Trust Securities to be redeemed will be allocated pro rata to the Trust Securities based upon the relative Liquidation Amounts of such classes. The particular Preferred Securities to be redeemed will be selected by the Property Trustee from the outstanding Preferred Securities not previously called for redemption, by such method as the Property Trustee deems fair and appropriate and which may provide for the selection for redemption of portions (equal to $10 or an integral multiple of $10 in excess thereof) of the Liquidation Amount of Preferred Securities of a denomination larger than $10. The Property Trustee will promptly notify the registrar for the Preferred Securities in writing of the Preferred Securities selected for redemption and, in the case of any Preferred Securities selected for partial redemption, the Liquidation Amount thereof to be redeemed. For all

31

purposes of the Trust Agreement, unless the context otherwise requires, all provisions relating to the redemption of Preferred Securities will relate to the portion of the aggregate Liquidation Amount of Preferred Securities which has been or is to be redeemed.

Notice of any redemption will be mailed at least 30 days but not more than 60 days before the Redemption Date to each holder of Trust Securities to be redeemed at its registered address. Unless the Company defaults in payment of the redemption price on the Junior Subordinated Debentures, on and after the Redemption Date interest will cease to accrue on such Junior Subordinated Debentures or portions thereof (and Distributions will cease to accrue on the related Preferred Securities or portions thereof) called for redemption.

SUBORDINATION OF THE COMMON SECURITIES

Payment of Distributions on, and the Redemption Price of, the Preferred Securities and Common Securities, as applicable, will be made pro rata based on the Liquidation Amount of the Preferred Securities and Common Securities; provided, however, that if on any Distribution Date or Redemption Date a Debenture Event of Default has occurred and is continuing, no payment of any Distribution on, or Redemption Price of, any of the Common Securities, and no other payment on account of the redemption, liquidation or other acquisition of such Common Securities, will be made unless payment in full in cash of all accumulated and unpaid Distributions on all of the outstanding Preferred Securities for all Distribution periods terminating on or prior thereto, or in the case of payment of the Redemption Price the full amount of such Redemption Price on all of the outstanding Preferred Securities then called for redemption, will have been made or provided for, and all funds available to the Property Trustee will first be applied to the payment in full in cash of all Distributions on, or Redemption Price of, the Preferred Securities then due and payable.

In the case of any Event of Default resulting from a Debenture Event of Default, the Company as holder of the Common Securities will be deemed to have waived any right to act with respect to any such Event of Default under the Trust Agreement until the effect of such Events of Default with respect to the Preferred Securities have been cured, waived or otherwise eliminated. Until any such Event of Default under the Trust Agreement with respect to the Preferred Securities has been so cured, waived or otherwise eliminated, the Property Trustee will act solely on behalf of the holders of the Preferred Securities and not on behalf of the Company, as holder of the Common Securities, and only the holders of the Preferred Securities will have the right to direct the Property Trustee to act on their behalf.

LIQUIDATION DISTRIBUTION UPON DISSOLUTION

The Company will have the right at any time to dissolve the Trust and cause the Junior Subordinated Debentures, after satisfaction of liabilities to creditors of the Trust, to be distributed to the holders of the Preferred Securities. Such right is subject, however, to the Company having received prior approval of the Federal Reserve if then required under applicable capital guidelines or policies of the Federal Reserve.

Pursuant to the Trust Agreement, the Trust will automatically dissolve upon expiration of its term and will dissolve earlier on the first to occur of
(i) certain events of bankruptcy, dissolution or liquidation of the Company,
(ii) the Company, as depositor, giving written direction to the Property Trustee to dissolve the Trust (which direction is optional and wholly within the discretion of the Company, as depositor), (iii) redemption of all of the Preferred Securities as described under "Redemption or Exchange--Mandatory Redemption," or (iv) the entry of an order for the dissolution of the Trust by a court of competent jurisdiction.

If an early dissolution occurs as described in clause (i), (ii) or (iv) of the preceding paragraph, the Trust will be liquidated by the Trustees as expeditiously as the Trustees determine to be possible by distributing, after satisfaction of liabilities to creditors of the Trust as provided by applicable law, to the holders of such Trust Securities a Like Amount of the Junior Subordinated Debentures, unless such distribution is determined by the

32

Property Trustee not to be practical, in which event such holders will be entitled to receive out of the assets of the Trust available for distribution to holders, after satisfaction of liabilities to creditors of the Trust as provided by applicable law, an amount equal to, in the case of holders of Preferred Securities, the aggregate of the Liquidation Amount plus accumulated but unpaid Distributions thereon to the date of payment (such amount being the "Liquidation Distribution"). If such Liquidation Distribution can be paid only in part because the Trust has insufficient assets available to pay in full the aggregate Liquidation Distribution, then the amounts payable directly by the Trust on the Preferred Securities will be paid on a pro rata basis. The Company, as the holder of the Common Securities, will be entitled to receive distributions upon any such liquidation pro rata with the holders of the Preferred Securities, except that, if a Debenture Event of Default has occurred and is continuing, the Preferred Securities will have a priority over the Common Securities. See "--Subordination of Common Securities."

Under current United States federal income tax law and interpretations and assuming, as expected, that the Trust is treated as a grantor trust, a distribution of the Junior Subordinated Debentures should not be a taxable event to holders of the Preferred Securities. Should there be a change in law, a change in legal interpretation, a Tax Event or other circumstances, however, the distribution could be a taxable event to holders of the Preferred Securities. See "Certain Federal Income Tax Consequences--Receipt of Junior Subordinated Debentures or Cash Upon Liquidation of the Trust." If the Company elects neither to redeem the Junior Subordinated Debentures prior to maturity nor to liquidate the Trust and distribute the Junior Subordinated Debentures to holders of the Preferred Securities, the Preferred Securities will remain outstanding until the repayment of the Junior Subordinated Debentures.

If the Company elects to dissolve the Trust and thereby causes the Junior Subordinated Debentures to be distributed to holders of the Preferred Securities in liquidation of the Trust, the Company will continue to have the right to shorten or extend the maturity of such Junior Subordinated Debentures, subject to certain conditions. See "Description of the Junior Subordinated Debentures--General."

LIQUIDATION VALUE

The amount of the Liquidation Distribution payable on the Preferred Securities in the event of any liquidation of the Trust is $10 per Preferred Security plus accrued but unpaid Distributions thereon to the date of payment, which may be in the form of a distribution of such amount in Junior Subordinated Debentures, subject to certain exceptions. See "--Liquidation Distribution Upon Dissolution."

EVENTS OF DEFAULT; NOTICE

Any one of the following events constitutes an event of default under the Trust Agreement (an "Event of Default") with respect to the Preferred Securities (whatever the reason for such Event of Default and whether voluntary or involuntary or effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body):

(i) the occurrence of a Debenture Event of Default (see "Description of the Junior Subordinated Debentures--Debenture Events of Default"); or

(ii) default by the Trust or the Property Trustee in the payment of any Distribution when it becomes due and payable, and continuation of such default for a period of 30 days; or

(iii) default by the Trust or the Property Trustee in the payment of any Redemption Price of any Trust Security when it becomes due and payable; or

33

(iv) default in the performance, or breach, in any material respect, of any covenant or warranty of the Trustees in the Trust Agreement (other than a covenant or warranty a default in the performance of which or the breach of which is dealt with in clauses (ii) or (iii) above), and continuation of such default or breach for a period of 60 days after there has been given, by registered or certified mail, to the Trustee(s) by the holders of at least 25% in aggregate Liquidation Amount of the outstanding Preferred Securities, a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a "Notice of Default" under the Trust Agreement; or

(v) the occurrence of certain events of bankruptcy or insolvency with respect to the Property Trustee and the failure by the Company to appoint a successor Property Trustee within 60 days thereof.

Within five Business Days after the occurrence of any Event of Default actually known to the Property Trustee, the Property Trustee will transmit notice of such Event of Default to the holders of the Preferred Securities, the Administrative Trustees and the Company, as depositor, unless such Event of Default has been cured or waived. The Company, as depositor, and the Administrative Trustees are required to file annually with the Property Trustee a certificate as to whether or not they are in compliance with all the conditions and covenants applicable to them under the Trust Agreement.

If a Debenture Event of Default has occurred and is continuing, the Preferred Securities will have a preference over the Common Securities upon dissolution of the Trust. See "--Liquidation Distribution Upon Dissolution." The existence of an Event of Default does not entitle the holders of Preferred Securities to accelerate the maturity thereof.

REMOVAL OF THE TRUST TRUSTEES

Unless a Debenture Event of Default has occurred and is continuing, any Trustee may be removed at any time by the holder of the Common Securities. If a Debenture Event of Default has occurred and is continuing, the Property Trustee and the Delaware Trustee may be removed at such time by the holders of a majority in Liquidation Amount of the outstanding Preferred Securities. In no event, however, will the holders of the Preferred Securities have the right to vote to appoint, remove or replace the Administrative Trustees, which voting rights are vested exclusively in the Company as the holder of the Common Securities. No resignation or removal of a Trustee and no appointment of a successor trustee will be effective until the acceptance of appointment by the successor trustee in accordance with the provisions of the Trust Agreement.

CO-TRUSTEES AND SEPARATE PROPERTY TRUSTEE

Unless an Event of Default has occurred and is continuing, at any time or times, for the purpose of meeting the legal requirements of the Trust Indenture Act or of any jurisdiction in which any part of the Trust Property (as defined in the Trust Agreement) may at the time be located, the Company, as the holder of the Common Securities, will have power to appoint one or more Persons (as defined in the Trust Agreement) either to act as a co-trustee, jointly with the Property Trustee, of all or any part of such Trust Property, or to act as separate trustee of any such Trust Property, in either case with such powers as may be provided in the instrument of appointment, and to vest in such Person or Persons in such capacity any property, title, right or power deemed necessary or desirable, subject to the provisions of the Trust Agreement. In case a Debenture Event of Default has occurred and is continuing, the Property Trustee alone will have power to make such appointment.

MERGER OR CONSOLIDATION OF TRUSTEES

Any Person into which the Property Trustee, the Delaware Trustee or any Administrative Trustee that is not a natural person may be merged or converted or with which it may be consolidated, or any Person resulting from any merger, conversion or consolidation to which such Trustee is a party, or any Person succeeding to all

34

or substantially all the corporate trust business of such Trustee, will be the successor of such Trustee under the Trust Agreement, provided such Person is otherwise qualified and eligible.

MERGERS, CONSOLIDATIONS, AMALGAMATIONS OR REPLACEMENTS OF THE TRUST

The Trust may not merge with or into, consolidate, amalgamate, or be replaced by, or convey, transfer or lease its properties and assets substantially as an entirety to any Person, except as described below. The Trust may, at the request of the Company, with the consent of the Administrative Trustees and without the consent of the holders of the Preferred Securities, the Property Trustee or the Delaware Trustee, merge with or into, consolidate, amalgamate, or be replaced by or convey, transfer or lease its properties and assets substantially as an entirety to a trust organized as such under the laws of any State; provided, that (i) such successor entity either (a) expressly assumes all of the obligations of the Trust with respect to the Preferred Securities, or (b) substitutes for the Preferred Securities other securities having substantially the same terms as the Preferred Securities (the "Successor Securities") so long as the Successor Securities rank the same as the Preferred Securities rank in priority with respect to distributions and payments upon liquidation, redemption and otherwise, (ii) the Company expressly appoints a trustee of such successor entity possessing the same powers and duties as the Property Trustee in its capacity as the holder of the Junior Subordinated Debentures, (iii) the Successor Securities are listed, or any Successor Securities will be listed upon notification of issuance, on any national securities exchange or other organization on which the Preferred Securities are then listed (including, if applicable, The Nasdaq Stock Market's National Market), if any, (iv) such merger, consolidation, amalgamation, replacement, conveyance, transfer or lease does not adversely affect the rights, preferences and privileges of the holders of the Preferred Securities (including any Successor Securities) in any material respect, (v) prior to such merger, consolidation, amalgamation, replacement, conveyance, transfer or lease, the Company has received an opinion from independent counsel to the effect that (a) such merger, consolidation, amalgamation, replacement, conveyance, transfer or lease does not adversely affect the rights, preferences and privileges of the holders of the Preferred Securities (including any Successor Securities) in any material respect, and (b) following such merger, consolidation, amalgamation, replacement, conveyance, transfer or lease, neither the Trust nor such successor entity will be required to register as an "investment company" under the Investment Company Act, and (vi) the Company owns all of the common securities of such successor entity and guarantees the obligations of such successor entity under the Successor Securities at least to the extent provided by the Guarantee, the Indenture, the Junior Subordinated Debentures, the Trust Agreement and the Expense Agreement. Notwithstanding the foregoing, the Trust will not, except with the consent of holders of 100% in Liquidation Amount of the Preferred Securities, consolidate, amalgamate, merge with or into, or be replaced by or convey, transfer or lease its properties and assets substantially as an entirety to any other Person or permit any other Person to consolidate, amalgamate, merge with or into, or replace it if such consolidation, amalgamation, merger, replacement, conveyance, transfer or lease would cause the Trust or the successor entity to be classified as other than a grantor trust for United States federal income tax purposes.

VOTING RIGHTS; AMENDMENT OF TRUST AGREEMENT

Except as provided below and under "Description of the Guarantee--Amendments and Assignment" and as otherwise required by the Trust Act and the Trust Agreement, the holders of the Preferred Securities will have no voting rights.

The Trust Agreement may be amended from time to time by the Company, the Property Trustee and the Administrative Trustees, without the consent of the holders of the Preferred Securities (i) with respect to acceptance of appointment by a successor trustee, (ii) to cure any ambiguity, correct or supplement any provisions in such Trust Agreement that may be inconsistent with any other provision, or to make any other provisions with respect to matters or questions arising under the Trust Agreement (provided such amendment is not inconsistent with the other provisions of the Trust Agreement), (iii) to modify, eliminate or add to any provisions of the Trust Agreement to such extent as is necessary to ensure that the Trust will be classified for United States federal income tax purposes as a grantor trust at all times that any Trust Securities are outstanding or to ensure that the Trust will

35

not be required to register as an "investment company" under the Investment Company Act, or (iv) to reduce or increase the Liquidation Amount per Trust Security and simultaneously to increase or reduce the number of Trust Securities issued and outstanding solely for the purpose of maintaining the eligibility of the Preferred Securities for listing or quotation on any national securities exchange or other organization on which the Preferred Securities are then listed or quoted (including, if applicable, The Nasdaq Stock Market's National Market); provided, however, that in the case of clause (ii), such action may not adversely affect in any material respect the interests of any holder of Trust Securities, and that, in the case of clause (iv), the aggregate Liquidation Amount of the Trust Securities outstanding, upon completion of any such reduction or increase must be the same as the aggregate Liquidation Amount of the Trust Securities outstanding immediately prior to any such reduction or increase, and any amendments of such Trust Agreement will become effective when notice thereof is given to the holders of Trust Securities (or, in the case of an amendment pursuant to clause (iv), as of the date specified in the notice). The Trust Agreement may be amended by the Trustees and the Company with (i) the consent of holders representing not less than a majority in the aggregate Liquidation Amount of the outstanding Trust Securities, and (ii) receipt by the Trustees of an opinion of counsel to the effect that such amendment or the exercise of any power granted to the Trustees in accordance with such amendment will not affect the Trust's status as a grantor trust for United States federal income tax purposes or the Trust's exemption from status as an "investment company" under the Investment Company Act. Notwithstanding anything in this paragraph to the contrary, without the consent of each holder of Trust Securities, the Trust Agreement may not be amended to (a) change the amount or timing of any Distribution on the Trust Securities or otherwise adversely affect the amount of any Distribution required to be made in respect of the Trust Securities as of a specified date, or (b) restrict the right of a holder of Trust Securities to institute suit for the enforcement of any such payment on or after such date.

The Trustees will not, so long as any Junior Subordinated Debentures are held by the Property Trustee, (i) direct the time, method and place of conducting any proceeding for any remedy available to the Debenture Trustee, or executing any trust or power conferred on the Property Trustee with respect to the Junior Subordinated Debentures, (ii) waive any past default that is waivable under the Indenture, (iii) exercise any right to rescind or annul a declaration that the principal of all the Junior Subordinated Debentures will be due and payable, or (iv) consent to any amendment, modification or termination of the Indenture or the Junior Subordinated Debentures, where such consent is required, without, in each case, obtaining the prior approval of the holders of a majority in aggregate Liquidation Amount of all outstanding Preferred Securities; provided, however, that where a consent under the Indenture requires the consent of each holder of Junior Subordinated Debentures affected thereby, no such consent will be given by the Property Trustee without the prior consent of each holder of the Preferred Securities. The Trustees may not revoke any action previously authorized or approved by a vote of the holders of the Preferred Securities except by subsequent vote of the holders of the Preferred Securities. The Property Trustee will notify each holder of Preferred Securities of any notice of default with respect to the Junior Subordinated Debentures. In addition to obtaining the foregoing approvals of the holders of the Preferred Securities, prior to taking any of the foregoing actions, the Trustees must obtain an opinion of counsel experienced in such matters to the effect that the Trust will not be classified as an association taxable as a corporation for United States federal income tax purposes on account of such action.

Any required approval of holders of Preferred Securities may be given at a meeting of holders of Preferred Securities convened for such purpose or pursuant to written consent. The Property Trustee will cause a notice of any meeting at which holders of Preferred Securities are entitled to vote, or of any matter upon which action by written consent of such holders is to be taken, to be given to each holder of record of Preferred Securities in the manner set forth in the Trust Agreement.

No vote or consent of the holders of Preferred Securities will be required for the Trust to redeem and cancel its Preferred Securities in accordance with the Trust Agreement.

Notwithstanding the fact that holders of Preferred Securities are entitled to vote or consent under any of the circumstances described above, any of the Preferred Securities that are owned by the Company, the Trustees or

36

any affiliate of the Company or any Trustee, will, for purposes of such vote or consent, be treated as if they were not outstanding.

PAYMENT AND PAYING AGENCY

Payments in respect of the Preferred Securities will be made by check mailed to the address of the holder entitled thereto as such address will appear on the register of holders of the Preferred Securities. The paying agent for the Preferred Securities will initially be the Property Trustee and any co-paying agent chosen by the Property Trustee and acceptable to the Administrative Trustees and the Company. The paying agent for the Preferred Securities may resign as paying agent upon 30 days' written notice to the Property Trustee and the Company. In the event that the Property Trustee no longer is the paying agent for the Preferred Securities, the Administrative Trustees will appoint a successor (which must be a bank or trust company acceptable to the Administrative Trustees and the Company) to act as paying agent.

REGISTRAR AND TRANSFER AGENT

The Property Trustee will act as the registrar and the transfer agent for the Preferred Securities. Registration of transfers of Preferred Securities will be effected without charge by or on behalf of the Trust, but upon payment of any tax or other governmental charges that may be imposed in connection with any transfer or exchange. The Trust will not be required to register or cause to be registered the transfer of Preferred Securities after such Preferred Securities have been called for redemption.

INFORMATION CONCERNING THE PROPERTY TRUSTEE

The Property Trustee, other than upon the occurrence and during the continuance of an Event of Default, undertakes to perform only such duties as are specifically set forth in the Trust Agreement and, upon the occurrence and during the continuance of an Event of Default, must exercise the same degree of care and skill as a prudent person would exercise or use in the conduct of his or her own affairs. Subject to this provision, the Property Trustee is under no obligation to exercise any of the powers vested in it by the Trust Agreement at the request of any holder of Preferred Securities unless it is offered reasonable indemnity against the costs, expenses and liabilities that might be incurred thereby. If no Event of Default has occurred and is continuing and the Property Trustee is required to decide between alternative causes of action, construe ambiguous provisions in the Trust Agreement or is unsure of the application of any provision of the Trust Agreement, and the matter is not one on which holders of Preferred Securities are entitled under the Trust Agreement to vote, then the Property Trustee will take such action as is directed by the Company and if not so directed, will take such action as it deems advisable and in the best interests of the holders of the Trust Securities and will have no liability except for its own bad faith, negligence or willful misconduct.

MISCELLANEOUS

The Administrative Trustees are authorized and directed to conduct the affairs of and to operate the Trust in such a way that the Trust will not be deemed to be an "investment company" required to be registered under the Investment Company Act or classified as an association taxable as a corporation for United States federal income tax purposes and so that the Junior Subordinated Debentures will be treated as indebtedness of the Company for United States federal income tax purposes. The Company and the Administrative Trustees are authorized, in this connection, to take any action, not inconsistent with applicable law, the certificate of trust of the Trust or the Trust Agreement, that the Company and the Administrative Trustees determine in their discretion to be necessary or desirable for such purposes.

Holders of the Preferred Securities have no preemptive or similar rights.

37

The Trust Agreement and the Preferred Securities will be governed by, and construed in accordance with, the internal laws of the State of Delaware.

DESCRIPTION OF THE JUNIOR SUBORDINATED DEBENTURES

Concurrently with the issuance of the Preferred Securities, the Trust will invest the proceeds thereof, together with the consideration paid by the Company for the Common Securities, in the Junior Subordinated Debentures issued by the Company. The Junior Subordinated Debentures will be issued as unsecured debt under the Indenture, to be dated as of April __, 1998 (the "Indenture"), between the Company and State Street Bank and Trust Company, as trustee (the "Debenture Trustee"). The Indenture will be qualified as an indenture under the Trust Indenture Act. The following summary of the material terms and provisions of the Junior Subordinated Debentures and the Indenture does not purport to be complete and is subject to, and is qualified in its entirety by reference to, the Indenture and to the Trust Indenture Act. Wherever particular defined terms of the Indenture are referred to, but not defined herein, such defined terms are incorporated herein by reference. The form of the Indenture has been filed as an exhibit to the Registration Statement of which this Prospectus forms a part.

GENERAL

The Junior Subordinated Debentures will be limited in aggregate principal amount to approximately $25,773,200 (or $29,639,180 if the Underwriters' over-allotment option is exercised) the sum of the aggregate stated Liquidation Amount of the Trust Securities'. The Junior Subordinated Debentures will bear interest at the annual rate of ___% of the principal amount thereof, payable quarterly in arrears on March 31, June 30, September 30, and December 31 of each year (each, an "Interest Payment Date") beginning September 30, 1998, to the Person (as defined in the Indenture) in whose name each Subordinated Debenture is registered, subject to certain exceptions, at the close of business on the fifteenth day of the last month of the calendar quarter. It is anticipated that, until the liquidation of the Trust, the Junior Subordinated Debentures will be held in the name of the Property Trustee in trust for the benefit of the holders of the Preferred Securities. The amount of interest payable for any period will be computed on the basis of a 360-day year of twelve 30-day months. In the event that any date on which interest is payable on the Junior Subordinated Debentures is not a Business Day, then payment of the interest payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or other payment in respect of any such delay), with the same force and effect as if made on the date such payment was originally payable. Accrued interest that is not paid on the applicable Interest Payment Date will bear additional interest on the amount thereof (to the extent permitted by law) at the rate per annum of __% thereof, compounded quarterly. The term "interest," as used herein, includes quarterly interest payments, interest on quarterly interest payments not paid on the applicable Interest Payment Date and Additional Interest, as applicable.

The Junior Subordinated Debentures will mature on June 30, 2029 (such date, as it may be shortened or extended as hereinafter described, the "Stated Maturity"). Such date may be shortened at any time by the Company to any date not earlier than June 30, 2003, subject to the Company having received prior approval of the Federal Reserve if then required under applicable capital guidelines or policies of the Federal Reserve. In the event that the Company elects to shorten or extend the Stated Maturity of the Junior Subordinated Debentures, it will give notice thereof to the Debenture Trustee, the Trust and to the holders of the Junior Subordinated Debentures no more than 180 days and no less than 90 days prior to the effectiveness thereof. The Company will not have the right to purchase the Junior Subordinated Debentures, in whole or in part, from the Trust until on or after June 30, 2003, except if a Tax Event, a Capital Treatment Event or an Investment Company Event has occurred and is continuing.

The Junior Subordinated Debentures will be unsecured and will rank junior and be subordinate in right of payment to all Senior Debt, Subordinated Debt and Additional Senior Obligations of the Company. Because the

38

Company is a holding company, the right of the Company to participate in any distribution of assets of the Bank, upon the Bank's liquidation or reorganization or otherwise (and thus the ability of holders of the Junior Subordinated Debentures to benefit indirectly from such distribution), is subject to the prior claim of creditors of the Bank, except to the extent that the Company may itself be recognized as a creditor of the Bank. The Junior Subordinated Debentures will, therefore, be effectively subordinated to all existing and future liabilities of the Bank, and holders of Junior Subordinated Debentures should look only to the assets of the Company for payments on the Junior Subordinated Debentures. The Indenture does not limit the incurrence or issuance of other secured or unsecured debt of the Company, including Senior Debt, Subordinated Debt and Additional Senior Obligations, whether under the Indenture or any existing indenture or other indenture that the Company may enter into in the future or otherwise. See "--Subordination."

The Indenture does not contain provisions that afford holders of the Junior Subordinated Debentures protection in the event of a highly leveraged transaction or other similar transaction involving the Company that may adversely affect such holders.

OPTION TO EXTEND INTEREST PAYMENT PERIOD

The Company has the right under the Indenture at any time during the term of the Junior Subordinated Debentures, so long as no Debenture Event of Default has occurred and is continuing, to defer the payment of interest at any time, or from time to time (each, an "Extension Period"). The right to defer the payment of interest on the Junior Subordinated Debentures is limited, however, to a period, in each instance, not exceeding 20 consecutive quarters and no Extension Period may extend beyond the Stated Maturity of the Junior Subordinated Debentures. At the end of each Extension Period, the Company must pay all interest then accrued and unpaid (together with interest thereon at the annual rate of __%, compounded quarterly, to the extent permitted by applicable law). During an Extension Period, interest will continue to accrue and holders of Junior Subordinated Debentures (or the holders of Preferred Securities if such securities are then outstanding) will be required to accrue and recognize income for United States federal income tax purposes. See "Certain Federal Income Tax Consequences--Potential Extension of Interest Payment Period and Original Issue Discount."

During any such Extension Period, the Company may not (i) declare or pay any dividends or distributions on, or redeem, purchase, acquire or make a liquidation payment with respect to, any of the Company's capital stock, (ii) make any payment of principal, interest or premium, if any, on or repay, repurchase or redeem any debt securities of the Company that rank pari passu with or junior in interest to the Junior Subordinated Debentures or make any guarantee payments with respect to any guarantee by the Company of the debt securities of any subsidiary of the Company if such guarantee ranks pari passu or junior in interest to the Junior Subordinated Debentures (other than payments under the Guarantee), or (iii) redeem, purchase or acquire less than all of the Junior Subordinated Debentures or any of the Preferred Securities. Prior to the termination of any such Extension Period, the Company may further defer the payment of interest; provided, that no Extension Period may exceed 20 consecutive quarters or extend beyond the Stated Maturity of the Junior Subordinated Debentures. Upon the termination of any such Extension Period and the payment of all amounts then due on any Interest Payment Date, the Company may elect to begin a new Extension Period subject to the above requirements. No interest will be due and payable during an Extension Period, except at the end thereof. The Company has no present intention of exercising its rights to defer payments of interest on the Junior Subordinated Debentures. The Company must give the Property Trustee, the Administrative Trustees and the Debenture Trustee notice of its election of such Extension Period at least two Business Days prior to the earlier of (i) the next succeeding date on which Distributions on the Trust Securities would have been payable except for the election to begin such Extension Period, or (ii) the date the Trust is required to give notice of the record date, or the date such Distributions are payable, to The Nasdaq Stock Market's National Market (or other applicable self-regulatory organization) or to holders of the Preferred Securities, but in any event at least one Business Day before such record date. Subject to the foregoing, there is no limitation on the number of times that the Company may elect to begin an Extension Period.

39

ADDITIONAL SUMS

If the Trust or the Property Trustee is required to pay any additional taxes, duties or other governmental charges as a result of the occurrence of a Tax Event, the Company will pay to the holders of the Junior Subordinated Debentures as additional amounts (referred to herein as "Additional Interest") on the Junior Subordinated Debentures such additional amounts as may be required so that the net amounts received and retained by the Trust after paying any such additional taxes, duties or other governmental charges will not be less than the amounts the Trust would have received had such additional taxes, duties or other governmental charges not been imposed.

REDEMPTION OR EXCHANGE

The Company will have the right to redeem the Junior Subordinated Debentures prior to maturity (i) on or after June 30, 2003, in whole at any time or in part from time to time, or (ii) at any time in whole (but not in part), within 180 days following the occurrence of a Tax Event, a Capital Treatment Event or an Investment Company Event, in each case at a redemption price equal to the accrued and unpaid interest on the Junior Subordinated Debentures so redeemed to the date fixed for redemption, plus 100% of the principal amount thereof. Any such redemption prior to the Stated Maturity will be subject to prior approval of the Federal Reserve if then required under applicable capital guidelines or policies of the Federal Reserve.

"Tax Event" means the receipt by the Trust of an opinion of counsel experienced in such matters to the effect that, as a result of any amendment to, or change (including any announced prospective change) in, the laws (or any regulations thereunder) of the United States or any political subdivision or taxing authority thereof or therein, or as a result of any official administrative pronouncement or judicial decision interpreting or applying such laws or regulations, which amendment or change is effective or which pronouncement or decision is announced on or after the date of issuance of the Preferred Securities under the Trust Agreement, there is more than an insubstantial risk that (i) the Trust is, or will be within 90 days after the date of such opinion of counsel, subject to United States federal income tax with respect to income received or accrued on the Junior Subordinated Debentures, (ii) interest payable by the Company on the Junior Subordinated Debentures is not, or within 90 days of the date of such opinion will not be, deductible by the Company, in whole or in part, for United States federal income tax purposes, or (iii) the Trust is, or will be within 90 days after the date of such opinion of counsel, subject to more than a de minimis amount of other taxes, duties, assessments or other governmental charges. The Company must request and receive an opinion with regard to such matters within a reasonable period of time after it becomes aware of the possible occurrence of any of the events described in clauses (i) through (iii) above.

"Capital Treatment Event" means the receipt by the Trust of an opinion of counsel experienced in such matters to the effect that, as a result of any amendment to or any change (including any announced prospective change) in the laws (or any regulations thereunder) of the United States or any political subdivision thereof or therein, or as a result of any official administrative pronouncement or judicial decision interpreting or applying such laws or regulations, which amendment or change is effective or which proposed change, pronouncement or decision is announced on or after the date of issuance of the Preferred Securities under the Trust Agreement, there is more than an insubstantial risk of impairment of the Company's ability to treat the aggregate Liquidation Amount of the Preferred Securities (or any substantial portion thereof) as "Tier 1 Capital" (or the then equivalent thereof) for purposes of the capital adequacy guidelines of the Federal Reserve, as then applicable to the Company; provided, however, that the inability of the Company to treat all or any portion of the Liquidation Amount of the Preferred Securities as Tier 1 Capital shall not constitute the basis for a Capital Treatment Event if such inability results from the Company having cumulative preferred capital in excess of the amount which may qualify for treatment as Tier 1 Capital under applicable capital adequacy guidelines of the Federal Reserve.

"Investment Company Event" means the receipt by the Trust of an opinion of counsel experienced in such matters to the effect that, as a result of the occurrence of a change in law or regulation or a change in interpretation

40

or application of law or regulation by any legislative body, court, governmental agency or regulatory authority, the Trust is or will be considered an "investment company" that is required to be registered under the Investment Company Act, which change becomes effective on or after the date of original issuance of the Preferred Securities.

Notice of any redemption will be mailed at least 30 days but not more than 60 days before the redemption date to each holder of Junior Subordinated Debentures to be redeemed at its registered address. Unless the Company defaults in payment of the redemption price for the Junior Subordinated Debentures, on and after the redemption date interest ceases to accrue on such Junior Subordinated Debentures or portions thereof called for redemption.

The Junior Subordinated Debentures will not be subject to any sinking fund.

DISTRIBUTION UPON LIQUIDATION

As described under "Description of the Preferred Securities--Liquidation Distribution Upon Dissolution," under certain circumstances involving the dissolution of the Trust, the Junior Subordinated Debentures may be distributed to the holders of the Preferred Securities in liquidation of the Trust after satisfaction of liabilities to creditors of the Trust as provided by applicable law. Any such distribution will be subject to receipt of prior approval by the Federal Reserve if then required under applicable policies or guidelines of the Federal Reserve. If the Junior Subordinated Debentures are distributed to the holders of Preferred Securities upon the dissolution of the Trust, the Company will use its best efforts to list the Junior Subordinated Debentures on The Nasdaq Stock Market's National Market or such stock exchanges, if any, on which the Preferred Securities are then listed. There can be no assurance as to the market price of any Junior Subordinated Debentures that may be distributed to the holders of Preferred Securities.

RESTRICTIONS ON CERTAIN PAYMENTS

If at any time (i) there has occurred a Debenture Event of Default,
(ii) the Company is in default with respect to its obligations under the Guarantee or (iii) the Company has given notice of its election of an Extension Period as provided in the Indenture with respect to the Junior Subordinated Debentures and has not rescinded such notice, or such Extension Period, or any extension thereof, is continuing, the Company will not (1) declare or pay any dividends or distributions on, or redeem, purchase, acquire, or make a liquidation payment with respect to, any of the Company's capital stock, (2) make any payment of principal, interest or premium, if any, on or repay or repurchase or redeem any debt securities of the Company that rank pari passu with or junior in interest to the Junior Subordinated Debentures or make any guarantee payments with respect to any guarantee by the Company of the debt securities of any subsidiary of the Company if such guarantee ranks pari passu or junior in interest to the Junior Subordinated Debentures (other than payments under the Guarantee), or (3) redeem, purchase or acquire less than all of the Junior Subordinated Debentures or any of the Preferred Securities.

SUBORDINATION

The Indenture provides that the Junior Subordinated Debentures are subordinated and junior in right of payment to all Senior Debt, Subordinated Debt and Additional Senior Obligations of the Company. Upon any payment or distribution of assets to creditors upon any liquidation, dissolution, winding up, reorganization, assignment for the benefit of creditors, marshaling of assets or any bankruptcy, insolvency, debt restructuring or similar proceedings in connection with any insolvency or bankruptcy proceedings of the Company, the holders of Senior Debt, Subordinated Debt and Additional Senior Obligations of the Company will first be entitled to receive payment in full of principal of (and premium on, if any) and interest on, if any, such Senior Debt, Subordinated Debt and Additional Senior Obligations of the Company before the holders of Junior Subordinated Debentures will be entitled to receive or retain any payment in respect of the principal of or interest on the Junior Subordinated Debentures.

41

In the event of the acceleration of the maturity of any Junior Subordinated Debentures, the holders of all Senior Debt, Subordinated Debt and Additional Senior Obligations of the Company outstanding at the time of such acceleration will first be entitled to receive payment in full of all amounts due thereon (including any amounts due upon acceleration) before the holders of the Junior Subordinated Debentures will be entitled to receive or retain any payment in respect of the principal of or interest on the Junior Subordinated Debentures.

No payments on account of principal or interest in respect of the Junior Subordinated Debentures may be made if there has occurred and is continuing a default in any payment with respect to Senior Debt, Subordinated Debt or Additional Senior Obligations of the Company or an event of default with respect to any Senior Debt, Subordinated Debt or Additional Senior Obligations of the Company resulting in the acceleration of the maturity thereof, or if any judicial proceeding is pending with respect to any such default.

"Debt" means, with respect to any Person, whether recourse is to all or a portion of the assets of such Person and whether or not contingent, (i) every obligation of such Person for money borrowed, (ii) every obligation of such Person evidenced by bonds, debentures, notes or other similar instruments, including obligations incurred in connection with the acquisition of property, assets or businesses, (iii) every reimbursement obligation of such Person with respect to letters of credit, bankers' acceptances or similar facilities issued for the account of such Person, (iv) every obligation of such Person issued or assumed as the deferred purchase price of property or services (but excluding trade accounts payable or accrued liabilities arising in the ordinary course of business), (v) every capital lease obligation of such Person, and (vi) every obligation of the type referred to in clauses (i) through (v) of another Person and all dividends of another Person the payment of which, in either case, such Person has guaranteed or is responsible or liable, directly or indirectly, as obligor or otherwise.

"Senior Debt" means, with respect to the Company, the principal of (and premium, if any) and interest, if any (including interest accruing on or after the filing of any petition in bankruptcy or for reorganization relating to the Company whether or not such claim for post-petition interest is allowed in such proceeding), on Debt, whether incurred on or prior to the date of the Indenture or thereafter incurred, unless, in the instrument creating or evidencing the same or pursuant to which the same is outstanding, it is provided that such obligations are not superior in right of payment to the Junior Subordinated Debentures or to other Debt which is pari passu with, or subordinated to, the Junior Subordinated Debentures; provided, however, that Senior Debt will not be deemed to include (i) any Debt of the Company which when incurred and without respect to any election under section 1111(b) of the United States Bankruptcy Code of 1978, as amended, was without recourse to the Company, (ii) any Debt of the Company to any of its subsidiaries, (iii) any Debt to any employee of the Company, (iv) any Debt which by its terms is subordinated to trade accounts payable or accrued liabilities arising in the ordinary course of business to the extent that payments made to the holders of such Debt by the holders of the Junior Subordinated Debentures as a result of the subordination provisions of the Indenture would be greater than they otherwise would have been as a result of any obligation of such holders to pay amounts over to the obligees on such trade accounts payable or accrued liabilities arising in the ordinary course of business as a result of subordination provisions to which such Debt is subject, and (v) Debt which constitutes Subordinated Debt.

"Subordinated Debt" means, with respect to the Company, the principal of (and premium, if any) and interest, if any (including interest accruing on or after the filing of any petition in bankruptcy or for reorganization relating to the Company whether or not such claim for post-petition interest is allowed in such proceeding), on Debt, whether incurred on or prior to the date of the Indenture or thereafter incurred, which is by its terms expressly provided to be junior and subordinate to other Debt of the Company (other than the Junior Subordinated Debentures).

"Additional Senior Obligations" means, with respect to the Company, all indebtedness, whether incurred on or prior to the date of the Indenture or thereafter incurred, for claims in respect of derivative products such as interest and foreign exchange rate contracts, commodity contracts and similar arrangements; provided, however, that Additional Senior Obligations do not include claims in respect of Senior Debt or Subordinated Debt or

42

obligations which, by their terms, are expressly stated to be not superior in right of payment to the Junior Subordinated Debentures or to rank pari passu in right of payment with the Junior Subordinated Debentures. "Claim," as used herein, has the meaning assigned thereto in Section 101(4) of the United States Bankruptcy Code of 1978, as amended.

The Indenture places no limitation on the amount of additional Senior Debt, Subordinated Debt or Additional Senior Obligations that may be incurred by the Company. The Company expects from time to time to incur additional indebtedness constituting Senior Debt, Subordinated Debt and Additional Senior Obligations. As of December 31, 1997, the Company had no outstanding Senior Debt, Subordinated Debt or Additional Senior Obligations. Because the Company is a holding company, the Junior Subordinated Debentures are effectively subordinated to all existing and future liabilities of the Company's subsidiaries, including obligations to depositors of the Bank.

PAYMENT AND PAYING AGENTS

Payment of principal of and any interest on the Junior Subordinated Debentures will be made at the office of the Debenture Trustee in Boston, Massachusetts, except that, at the option of the Company, payment of any interest may be made (i) by check mailed to the address of the Person entitled thereto as such address appears in the register of holders of the Junior Subordinated Debentures, or (ii) by transfer to an account maintained by the Person entitled thereto as specified in the register of holders of the Junior Subordinated Debentures, provided that proper transfer instructions have been received by the regular record date. Payment of any interest on Junior Subordinated Debentures will be made to the Person in whose name such Subordinated Debenture is registered at the close of business on the regular record date for such interest, except in the case of defaulted interest. The Company may at any time designate additional paying agents for the Junior Subordinated Debentures or rescind the designation of any paying agent for the Junior Subordinated Debentures; however, the Company will at all times be required to maintain a paying agent in Boston, Massachusetts and each place of payment for the Junior Subordinated Debentures.

Any moneys deposited with the Debenture Trustee or any paying agent for the Junior Subordinated Debentures, or then held by the Company in trust, for the payment of the principal of or interest on the Junior Subordinated Debentures and remaining unclaimed for two years after such principal or interest has become due and payable will be repaid to the Company on May 31 of each year or (if then held in trust by the Company) will be discharged from such trust and the holder of such Junior Subordinated Debenture will thereafter look, as a general unsecured creditor, only to the Company for payment thereof.

REGISTRAR AND TRANSFER AGENT

The Debenture Trustee will act as the registrar and the transfer agent for the Junior Subordinated Debentures. Junior Subordinated Debentures may be presented for registration of transfer (with the form of transfer endorsed thereon, or a satisfactory written instrument of transfer, duly executed), in Boston, Massachusetts or at the office of the registrar in Boston, Massachusetts. The Company may at any time rescind the designation of any such transfer agent or approve a change in the location through which any such transfer agent acts. The Company may at any time designate additional transfer agents with respect to the Junior Subordinated Debentures. In the event of any redemption, neither the Company nor the Debenture Trustee will be required to
(i) issue, register the transfer of or exchange Junior Subordinated Debentures during a period beginning at the opening of business 15 days before the day of selection for redemption of Junior Subordinated Debentures and ending at the close of business on the day of mailing of the relevant notice of redemption, or
(ii) transfer or exchange any Junior Subordinated Debentures so selected for redemption, except, in the case of any Junior Subordinated Debentures being redeemed in part, any portion thereof not to be redeemed.

43

MODIFICATION OF INDENTURE

The Company and the Debenture Trustee may, from time to time without the consent of the holders of the Junior Subordinated Debentures, amend, waive or supplement the Indenture for specified purposes, including, among other things, curing ambiguities, defects or inconsistencies and qualifying, or maintaining the qualification of, the Indenture under the Trust Indenture Act. The Indenture contains provisions permitting the Company and the Debenture Trustee, with the consent of the holders of not less than a majority in principal amount of the outstanding Junior Subordinated Debentures, to modify the Indenture; provided, that no such modification may, without the consent of the holder of each outstanding Subordinated Debenture affected by such proposed modification, (i) extend the fixed maturity of the Junior Subordinated Debentures, or reduce the principal amount thereof, or reduce the rate or extend the time of payment of interest thereon, or (ii) reduce the percentage of principal amount of Junior Subordinated Debentures, the holders of which are required to consent to any such modification of the Indenture; provided that so long as any of the Preferred Securities remain outstanding, no such modification may be made that requires the consent of the holders of the Junior Subordinated Debentures, and no termination of the Indenture may occur, and no waiver of any Debenture Event of Default may be effective, without the prior consent of the holders of at least a majority of the aggregate Liquidation Amount of the Preferred Securities and that if the consent of the holder of each Subordinated Debenture is required, such modification will not be effective until each holder of Trust Securities has consented thereto.

DEBENTURE EVENTS OF DEFAULT

The Indenture provides that any one or more of the following described events with respect to the Junior Subordinated Debentures that has occurred and is continuing constitutes an event of default (each, a "Debenture Event of Default") with respect to the Junior Subordinated Debentures:

(i) failure for 30 days to pay any interest on the Junior Subordinated Debentures, when due (subject to the deferral of any due date in the case of an Extension Period); or

(ii) failure to pay any principal on the Junior Subordinated Debentures when due whether at maturity, upon redemption by declaration or otherwise; or

(iii) failure to observe or perform in any material respect certain other covenants contained in the Indenture for 90 days after written notice to the Company from the Debenture Trustee or the holders of at least 25% in aggregate outstanding principal amount of the Junior Subordinated Debentures; or

(iv) certain events in bankruptcy, insolvency or reorganization of the Company.

The holders of a majority in aggregate outstanding principal amount of the Junior Subordinated Debentures have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Debenture Trustee. The Debenture Trustee, or the holders of not less than 25% in aggregate outstanding principal amount of the Junior Subordinated Debentures, may declare the principal due and payable immediately upon a Debenture Event of Default. The holders of a majority in aggregate outstanding principal amount of the Junior Subordinated Debentures may annul such declaration and waive the default if the default (other than the non-payment of the principal of the Junior Subordinated Debentures which has become due solely by such acceleration) has been cured and a sum sufficient to pay all matured installments of interest and principal due otherwise than by acceleration has been deposited with the Debenture Trustee. Should the holders of the Junior Subordinated Debentures fail to annul such declaration and waive such default, the holders of a majority in aggregate Liquidation Amount of the Preferred Securities will have such right.

The Company is required to file annually with the Debenture Trustee a certificate as to whether or not the Company is in compliance with all the conditions and covenants applicable to it under the Indenture.

44

If a Debenture Event of Default has occurred and is continuing, the Property Trustee will have the right to declare the principal of and the interest on such Junior Subordinated Debentures, and any other amounts payable under the Indenture, to be forthwith due and payable and to enforce its other rights as a creditor with respect to such Junior Subordinated Debentures.

ENFORCEMENT OF CERTAIN RIGHTS BY HOLDERS OF THE PREFERRED SECURITIES

If a Debenture Event of Default has occurred and is continuing and such event is attributable to the failure of the Company to pay interest on or principal of the Junior Subordinated Debentures on the payment date on which such payment is due and payable, then a holder of Preferred Securities may institute a legal proceeding directly against the Company for enforcement of payment to such holder of the principal of or interest on such Junior Subordinated Debentures having a principal amount equal to the aggregate Liquidation Amount of the Preferred Securities of such holder (a "Direct Action"). In connection with such Direct Action, the Company will have a right of set-off under the Indenture to the extent of any payment made by the Company to such holder of Preferred Securities in the Direct Action. The Company may not amend the Indenture to remove the foregoing right to bring a Direct Action without the prior written consent of the holders of all of the Preferred Securities. If the right to bring a Direct Action is removed, the Trust may become subject to the reporting obligations under the Exchange Act. The Company has the right under the Indenture to set-off any payment made to such holder of Preferred Securities by the Company in connection with a Direct Action.

The holders of the Preferred Securities will not be able to exercise directly any remedies, other than those set forth in the preceding paragraph, available to the holders of the Junior Subordinated Debentures unless there has been an Event of Default under the Trust Agreement. See "Description of the Preferred Securities--Events of Default; Notice."

CONSOLIDATION, MERGER, SALE OF ASSETS AND OTHER TRANSACTIONS

The Company may not consolidate with or merge into any other Person or convey or transfer its properties and assets substantially as an entirety to any Person, and no Person may consolidate with or merge into the Company or sell, convey, transfer or otherwise dispose of its properties and assets substantially as an entirety to the Company, unless (i) in the event the Company consolidates with or merges into another Person or conveys or transfers its properties and assets substantially as an entirety to any Person, the successor Person is organized under the laws of the United States or any State or the District of Columbia, and such successor Person expressly assumes by supplemental indenture the Company obligations on the Junior Subordinated Debentures, (ii) immediately after giving effect thereto, no Debenture Event of Default, and no event which, after notice or lapse of time or both, would become a Debenture Event of Default, has occurred and is continuing, and (iii) certain other conditions prescribed in the Indenture are met.

SATISFACTION AND DISCHARGE

The Indenture will cease to be of further effect (except as to the Company's obligations to pay certain sums due pursuant to the Indenture and to provide certain officers' certificates and opinions of counsel described therein) and the Company will be deemed to have satisfied and discharged the Indenture when, among other things, all Junior Subordinated Debentures not previously delivered to the Debenture Trustee for cancellation (i) have become due and payable, or (ii) will become due and payable at their Stated Maturity within one year or are to be called for redemption within one year, and the Company deposits or causes to be deposited with the Debenture Trustee funds, in trust, for the purpose and in an amount sufficient to pay and discharge the entire indebtedness on the Junior Subordinated Debentures not previously delivered to the Debenture Trustee for cancellation, for the principal and interest to the date of the deposit or to the Stated Maturity or redemption date, as the case may be.

45

GOVERNING LAW

The Indenture and the Junior Subordinated Debentures will be governed by and construed in accordance with the laws of The Commonwealth of Massachusetts.

INFORMATION CONCERNING THE DEBENTURE TRUSTEE

The Debenture Trustee has and is subject to all the duties and responsibilities specified with respect to an indenture trustee under the Trust Indenture Act. Subject to such provisions, the Debenture Trustee is under no obligation to exercise any of the powers vested in it by the Indenture at the request of any holder of Junior Subordinated Debentures, unless offered reasonable indemnity by such holder against the costs, expenses and liabilities which might be incurred thereby. The Debenture Trustee is not required to expend or risk its own funds or otherwise incur personal financial liability in the performance of its duties if the Debenture Trustee reasonably believes that repayment or adequate indemnity is not reasonably assured to it.

MISCELLANEOUS

The Company has agreed, pursuant to the Indenture, for so long as Trust Securities remain outstanding, (i) to maintain directly or indirectly 100% ownership of the Common Securities of the Trust (provided that certain successors which are permitted pursuant to the Indenture may succeed to the Company's ownership of the Common Securities), (ii) not to voluntarily dissolve the Trust, except upon prior approval of the Federal Reserve if then so required under applicable capital guidelines or policies of the Federal Reserve, and (a) in connection with a distribution of Junior Subordinated Debentures to the holders of the Preferred Securities in liquidation of the Trust, or (b) in connection with certain mergers, consolidations or amalgamations permitted by the Trust Agreement, and (iii) to use its reasonable efforts, consistent with the terms and provisions of the Trust Agreement, to cause the Trust to remain classified as a grantor trust and not as an association taxable as a corporation for United States federal income tax purposes.

DESCRIPTION OF THE GUARANTEE

The Preferred Securities Guarantee Agreement (the "Guarantee") will be executed and delivered by the Company concurrently with the issuance of the Preferred Securities for the benefit of the holders of the Preferred Securities. The Guarantee will be qualified as an indenture under the Trust Indenture Act. The Guarantee Trustee will act as indenture trustee under the Guarantee for purposes of complying with the provisions of the Trust Indenture Act. The Guarantee Trustee, State Street Bank and Trust Company, will hold the Guarantee for the benefit of the holders of the Preferred Securities. The following summary of the material terms and provisions of the Guarantee does not purport to be complete and is subject to, and qualified in its entirety by reference to, all of the provisions of the Guarantee and the Trust Indenture Act. Wherever particular defined terms of the Guarantee are referred to, but not defined herein, such defined terms are incorporated herein by reference. The form of the Guarantee has been filed as an exhibit to the Registration Statement of which this Prospectus forms a part.

GENERAL

The Company will, pursuant to the Guarantee, irrevocably agree to pay in full on a subordinated basis, to the extent set forth therein, the Guarantee Payments (as defined below) to the holders of the Preferred Securities, as and when due, regardless of any defense, right of set-off or counterclaim that the Trust may have or assert other than the defense of payment. The following payments with respect to the Preferred Securities, to the extent not paid by or on behalf of the Trust (the "Guarantee Payments"), will be subject to the Guarantee: (i) any accrued and unpaid Distributions required to be paid on the Preferred Securities, to the extent that the Trust has funds available therefor at such time, (ii) the Redemption Price with respect to any Preferred Securities called for

46

redemption, to the extent that the Trust has funds available therefor at such time, and (iii) upon a voluntary or involuntary dissolution, winding up or liquidation of the Trust (other than in connection with the distribution of Junior Subordinated Debentures to the holders of Preferred Securities or a redemption of all of the Preferred Securities), the lesser of (a) the amount of the Liquidation Distribution, to the extent the Trust has funds available therefor at such time, and (b) the amount of assets of the Trust remaining available for distribution to holders of Preferred Securities in liquidation of the Trust. The obligation of the Company to make a Guarantee Payment may be satisfied by direct payment of the required amounts by the Company to the holders of the Preferred Securities or by causing the Trust to pay such amounts to such holders.

The Guarantee will not apply to any payment of Distributions except to the extent the Trust has funds available therefor. If the Company does not make interest payments on the Junior Subordinated Debentures held by the Trust, the Trust will not pay Distributions on the Preferred Securities and will not have funds legally available therefor.

STATUS OF THE GUARANTEE

The Guarantee will constitute an unsecured obligation of the Company and will rank subordinate and junior in right of payment to all Senior Debt, Subordinated Debt and Additional Senior Obligations of the Company in the same manner as the Junior Subordinated Debentures. The Guarantee does not place a limitation on the amount of additional Senior Debt, Subordinated Debt or Additional Senior Obligations that may be incurred by the Company. The Company expects from time to time to incur additional indebtedness constituting Senior Debt, Subordinated Debt and Additional Senior Obligations.

The Guarantee will constitute a guarantee of payment and not of collection (that is, the guaranteed party may institute a legal proceeding directly against the Company to enforce its rights under the Guarantee without first instituting a legal proceeding against any other Person). The Guarantee will not be discharged except by payment of the Guarantee Payments in full to the extent not paid by the Trust or upon distribution of the Junior Subordinated Debentures to the holders of the Preferred Securities. Because the Company is a holding company, the right of the Company to participate in any distribution of assets of the Bank upon the Bank's liquidation or reorganization or otherwise is subject to the prior claims of creditors of the Bank, except to the extent the Company may itself be recognized as a creditor of the Bank. The Company's obligations under the Guarantee, therefore, will be effectively subordinated to all existing and future liabilities of the Company's subsidiaries, and claimants should look only to the assets of the Company for payments thereunder.

AMENDMENTS AND ASSIGNMENT

Except with respect to any changes which do not materially adversely affect the rights of holders of the Preferred Securities (in which case no vote will be required), the Guarantee may not be amended without the prior approval of the holders of not less than a majority of the aggregate Liquidation Amount of the outstanding Preferred Securities. See "Description of the Preferred Securities--Voting Rights; Amendment of Trust Agreement." All guarantees and agreements contained in the Guarantee will bind the successors, assigns, receivers, trustees and representatives of the Company and will inure to the benefit of the holders of the Preferred Securities then outstanding.

EVENTS OF DEFAULT

An event of default under the Guarantee will occur upon the failure of the Company to perform any of its payment or other obligations thereunder. The holders of not less than a majority in aggregate Liquidation Amount of the Preferred Securities have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Guarantee Trustee in respect of the Guarantee or to direct the exercise of any trust or power conferred upon the Guarantee Trustee under the Guarantee.

47

Any holder of Preferred Securities may institute a legal proceeding directly against the Company to enforce its rights under the Guarantee without first instituting a legal proceeding against the Trust, the Guarantee Trustee or any other Person.

The Company, as guarantor, is required to file annually with the Guarantee Trustee a certificate as to whether or not the Company is in compliance with all the conditions and covenants applicable to it under the Guarantee.

INFORMATION CONCERNING THE GUARANTEE TRUSTEE

The Guarantee Trustee, other than during the occurrence and continuance of a default by the Company in performance of the Guarantee, undertakes to perform only such duties as are specifically set forth in the Guarantee and, after default with respect to the Guarantee, must exercise the same degree of care and skill as a prudent person would exercise or use in the conduct of his or her own affairs. Subject to such provisions, the Guarantee Trustee is under no obligation to exercise any of the powers vested in it by the Guarantee at the request of any holder of any Preferred Securities, unless it is offered reasonable indemnity against the costs, expenses and liabilities that might be incurred thereby.

TERMINATION OF THE GUARANTEE

The Guarantee will terminate and be of no further force and effect upon
(a) full payment of the Redemption Price of the Preferred Securities, (b) full payment of the amounts payable upon liquidation of the Trust, or (c) distribution of the Junior Subordinated Debentures to the holders of the Preferred Securities. The Guarantee will continue to be effective or will be reinstated, as the case may be, if at any time any holder of the Preferred Securities must restore payment of any sums paid under such Preferred Securities or the Guarantee.

GOVERNING LAW

The Guarantee will be governed by and construed in accordance with the laws of The Commonwealth of Massachusetts.

EXPENSE AGREEMENT

The Company will, pursuant to the Agreement as to Expenses and Liabilities entered into by it under the Trust Agreement (the "Expense Agreement"), irrevocably and unconditionally guarantee to each person or entity to whom the Trust becomes indebted or liable, the full payment of any costs, expenses or liabilities of the Trust, other than obligations of the Trust to pay to the holders of the Preferred Securities or other similar interests in the Trust of the amounts due such holders pursuant to the terms of the Preferred Securities or such other similar interests, as the case may be. Third party creditors of the Trust may proceed directly against the Company under the Expense Agreement, regardless of whether such creditors had notice of the Expense Agreement.

RELATIONSHIP AMONG THE PREFERRED SECURITIES,
THE JUNIOR SUBORDINATED DEBENTURES AND THE GUARANTEE

FULL AND UNCONDITIONAL GUARANTEE

Payments of Distributions and other amounts due on the Preferred Securities (to the extent the Trust has funds available for the payment of such Distributions) are irrevocably guaranteed by the Company as and to the extent set forth under "Description of the Guarantee." The Company and the Trust believe that, taken together,

48

the obligations of the Company under the Junior Subordinated Debentures, the Indenture, the Trust Agreement, the Expense Agreement, and the Guarantee provide, in the aggregate, a full, irrevocable and unconditional guarantee, on a subordinated basis, of payment of Distributions and other amounts due on the Preferred Securities. No single document standing alone or operating in conjunction with fewer than all of the other documents constitutes such guarantee. It is only the combined operation of these documents that has the effect of providing a full, irrevocable and unconditional guarantee of the obligations of the Trust under the Preferred Securities. If and to the extent that the Company does not make payments on the Junior Subordinated Debentures, the Trust will not pay Distributions or other amounts due on the Preferred Securities. The Guarantee does not cover payment of Distributions when the Trust does not have sufficient funds to pay such Distributions. In such event, the remedy of a holder of Preferred Securities is to institute a legal proceeding directly against the Company for enforcement of payment of such Distributions to such holder. The obligations of the Company under the Guarantee are subordinate and junior in right of payment to all Senior Debt, Subordinated Debt and Additional Senior Obligations of the Company.

SUFFICIENCY OF PAYMENTS

As long as payments of interest and other payments are made when due on the Junior Subordinated Debentures, such payments will be sufficient to cover Distributions and other payments due on the Preferred Securities, primarily because (i) the aggregate principal amount of the Junior Subordinated Debentures will be equal to the sum of the aggregate stated Liquidation Amount of the Trust Securities, (ii) the interest rate and interest and other payment dates on the Junior Subordinated Debentures will match the Distribution rate and Distribution and other payment dates for the Preferred Securities, (iii) the Company will pay for all and any costs, expenses and liabilities of the Trust (except the obligations of the Trust to holders of the Preferred Securities), and (iv) the Trust Agreement further provides that the Trust will not engage in any activity that is not consistent with the limited purposes of the Trust.

ENFORCEMENT RIGHTS OF HOLDERS OF PREFERRED SECURITIES

A holder of any Preferred Security may institute a legal proceeding directly against the Company to enforce its rights under the Guarantee without first instituting a legal proceeding against the Guarantee Trustee, the Trust or any other Person. A default or event of default under any Senior Debt, Subordinated Debt or Additional Senior Obligations of the Company would not constitute a default or Event of Default. In the event, however, of payment defaults under, or acceleration of, Senior Debt, Subordinated Debt or Additional Senior Obligations of the Company, the subordination provisions of the Indenture provide that no payments may be made in respect of the Junior Subordinated Debentures until such Senior Debt, Subordinated Debt or Additional Senior Obligations has been paid in full or any payment default thereunder has been cured or waived. Failure to make required payments on the Junior Subordinated Debentures would constitute an Event of Default.

LIMITED PURPOSE OF THE TRUST

The Preferred Securities evidence a preferred undivided beneficial interest in the assets of the Trust. The Trust exists for the exclusive purposes of (i) issuing the Trust Securities representing undivided beneficial interests in the assets of the Trust, (ii) investing the gross proceeds of the Trust Securities in the Junior Subordinated Debentures issued by the Company, and
(iii) engaging in only those other activities necessary, advisable, or incidental thereto. A principal difference between the rights of a holder of a Preferred Security and the rights of a holder of a Subordinated Debenture is that a holder of a Subordinated Debenture is entitled to receive from the Company the principal amount of and interest accrued on Junior Subordinated Debentures held, while a holder of Preferred Securities is entitled to receive Distributions from the Trust (or from the Company under the Guarantee) if and to the extent the Trust has funds available for the payment of such Distributions.

49

RIGHTS UPON DISSOLUTION

Upon any voluntary or involuntary dissolution of the Trust involving the liquidation of the Junior Subordinated Debentures, the holders of the Preferred Securities will be entitled to receive, out of assets held by the Trust, the Liquidation Distribution in cash. See "Description of the Preferred Securities--Liquidation Distribution Upon Dissolution." Upon any voluntary or involuntary liquidation or bankruptcy of the Company, the Property Trustee, as holder of the Junior Subordinated Debentures, would be a subordinated creditor of the Company, subordinated in right of payment to all Senior Debt, Subordinated Debt and Additional Senior Obligations of the Company (as set forth in the Indenture), but entitled to receive payment in full of principal and interest before any shareholders of the Company receive payments or distributions. Since the Company is the guarantor under the Guarantee and has agreed to pay for all costs, expenses and liabilities of the Trust (other than the obligations of the Trust to the holders of its Preferred Securities), the positions of a holder of the Preferred Securities and a holder of the Junior Subordinated Debentures relative to other creditors and to shareholders of the Company in the event of liquidation or bankruptcy of the Company are expected to be substantially the same.

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

GENERAL

The following is a summary of the principal United States federal income tax consequences of the purchase, ownership and disposition of Preferred Securities which has been passed upon by Foley, Hoag & Eliot LLP, counsel to the Company and the Trust insofar as it relates to matters of law and legal conclusions. The discussion only addresses the tax consequences to a person that acquires Preferred Securities on their original issue at their original offering price and that is (i) an individual citizen or resident of the United States,
(ii) a corporation or partnership organized in or under the laws of the United States or any state thereof or the District of Columbia or (iii) an estate or trust the income of which is subject to United States federal income tax regardless of source. This discussion does not attempt to discuss all tax consequences that may be applicable to a holder of Preferred Securities, nor does it address the tax consequences to (i) persons who are not United States Persons, (ii) persons that may be subject to special tax treatment under United States federal income tax law, such as banks, insurance companies, thrift institutions, real estate investment trusts, regulated investment companies, tax-exempt organizations, and dealers in securities or currencies, (iii) persons that will hold the Preferred Securities as part of a position in a "straddle," as part of a "hedge or "synthetic security," as part of a "conversion transaction" or other integrated investment transaction for federal income tax purposes, or as other than a capital asset, or (iv) persons whose functional currency is not the United States dollar. Further, it does not include any description of any alternative minimum tax consequences or the tax laws of any state or local government or of any foreign government that may be applicable to the Preferred Securities.

The summary is based on current provisions of the Internal Revenue Code of 1986, as amended (the "Code"), Treasury regulations thereunder and administrative and judicial interpretations thereof, all of which are subject to change, with possible retroactive effect. Subsequent changes may cause tax consequences to vary substantially from the consequences described below. Furthermore, the authorities on which this summary is based are subject to various interpretations, and it is therefore possible that the federal income tax treatment of the purchase, ownership and disposition of Preferred Securities may differ from the treatment described below.

CLASSIFICATION OF THE TRUST

Under current law and assuming full compliance with the terms of the Trust Agreement and Indenture (and certain other documents described herein), the Trust will be classified for United States federal income tax purposes as a grantor trust and not as an association taxable as a corporation. As a result, each holder of Preferred Securities generally will be considered the owner of an undivided beneficial interest in the Junior Subordinated Debentures. Accordingly, for United States federal income tax purposes, each holder of Preferred Securities will

50

be required to include in its gross income any interest, including original issue discount, paid or accrued with respect to its allocable share of the Junior Subordinated Debentures whether or not cash is actually distributed to such holder.

CLASSIFICATION OF THE JUNIOR SUBORDINATED DEBENTURES

The Company intends to take the position that the Junior Subordinated Debentures will be classified for United States federal income tax purposes as indebtedness of the Company under current law and each holder of Preferred Securities will be treated as owning an indirect beneficial interest in the Junior Subordinated Debentures. No ruling is being requested from the Internal Revenue Service and there is no direct authority addressing the characterization of the Junior Subordinated Debentures. No assurance can be given that such position of the Company will not be challenged by the Internal Revenue Service or, if challenged that such a challenge will not be successful. The remainder of this discussion assumes that the Junior Subordinated Debentures will be classified for United States federal income tax purposes as indebtedness of the Company.

POTENTIAL EXTENSION OF INTEREST PAYMENT PERIOD AND ORIGINAL ISSUE DISCOUNT

Under recently issued Treasury regulations (the "Regulations"), a debt instrument will be deemed to be issued with original issue discount ("OID") if there is more than a "remote" contingency that periodic stated interest payments due on the instrument will not be timely paid. Because the exercise by the Company of its option to defer the payment of stated interest on the Junior Subordinated Debentures would prevent the Company from declaring dividends on any class of equity, the Company believes that the likelihood of its exercising the option is "remote" within the meaning of the Regulations. As a result, the Company intends to take the position that the Junior Subordinated Debentures will not be considered to be issued with OID. Accordingly, based on this position, stated interest on the Junior Subordinated Debentures will be includible in the ordinary income of a holder at the time that such payments are paid or accrued in accordance with such holder's regular method of tax accounting. Because the Regulations have not yet been addressed in any published rulings or other published interpretations issued by the Internal Revenue Service, it is possible that the Internal Revenue Service could take a position contrary to the position taken by the Company.

Under the Regulations, if the Company were to exercise its option to defer the payment of stated interest on the Junior Subordinated Debentures, the Junior Subordinated Debentures would at that time be treated as issued with OID and all stated interest on the Junior Subordinated Debentures would thereafter be treated as OID as long as the Junior Subordinated Debentures remain outstanding. In such event, a holder of the Junior Subordinated Debentures would be required to include OID in ordinary income, on a current basis, over the period that the instrument is held even though the Company would not be making any actual cash payments during the extended interest payment period. The amount of interest income includible in the taxable income of a holder of the Junior Subordinated Debentures would be determined on the basis of a constant yield method over the remaining term of the instrument and the actual receipt of future payments of stated interest on the Junior Subordinated Debentures would no longer be separately reported as taxable income. The amount of OID that would accrue, in the aggregate, during the extended interest payment period would be approximately equal to the amount of the cash payment due at the end of such period. Any OID included in income would increase the holder's adjusted tax basis in the Junior Subordinated Debentures and the holder's actual receipt of interest payments would reduce such basis.

Because income on the Preferred Securities will constitute interest or OID, corporate holders of Preferred Securities will not be entitled to a dividends-received deduction with respect to any income recognized with respect to the Preferred Securities.

MARKET DISCOUNT AND ACQUISITION PREMIUM

51

Holders of Preferred Securities other than a holder who purchased the Preferred Securities upon original issuance may be considered to have acquired their undivided interest in the Junior Subordinated Debentures with "market discount' or acquisition premium" as such phrases are defined for United States federal income tax purposes. Such holders are advised to consult their tax advisors as to the income tax consequences of the acquisition, ownership and disposition of the Preferred Securities.

RECEIPT OF JUNIOR SUBORDINATED DEBENTURES OR CASH UPON LIQUIDATION OF THE TRUST

Under certain circumstances, as described herein (see "Description of the Preferred Securities -- Redemption or Exchange" and "Description of the Preferred Securities -- Liquidation Distribution Upon Dissolution"), the Junior Subordinated Debentures may be distributed to holders of Preferred Securities upon a liquidation of the Trust. Under current United States federal income tax law, such a distribution would be treated as a nontaxable event to each such holder and would result in such holder having an adjusted tax basis in the Junior Subordinated Debentures received in the liquidation equal to such holder's adjusted tax basis in the Preferred Securities immediately before the distribution. A holder's holding period in the Junior Subordinated Debentures so received in liquidation of the Trust would include the period for which such holder held the Preferred Securities. If, however, the Trust is characterized for United States federal income tax purposes as an association taxable as a corporation at the time of its dissolution, the distribution of the Junior Subordinated Debentures may constitute a taxable event to holders of Preferred Securities.

Under certain circumstances described herein, the Junior Subordinated Debentures may be redeemed for cash and the proceeds of such redemption distributed to holders in redemption of their Preferred Securities. Under current law, such a redemption would, for United States federal income tax purposes, constitute a taxable disposition of the redeemed Preferred Securities, and a holder would recognize gain or loss as if the holder sold such Preferred Securities for cash. See "Description of the Preferred Securities -- Redemption or Exchange" and "Description of the Preferred Securities -- Liquidation Distribution Upon Dissolution."

DISPOSITION OF PREFERRED SECURITIES

Upon the sale of the Preferred Securities, a holder will recognize gain or loss in an amount equal to the difference between its adjusted tax basis in the Preferred Securities and the amount realized in the sale (except to the extent of any amount received in respect of accrued but unpaid interest not previously included in income). A holder's adjusted tax basis in the Preferred Securities generally will be its initial purchase price increased by the amount of OID accrued and decreased by payments (if any) received on the Preferred Securities in respect of OID (if any) to the date of disposition. Such gain or loss generally will be a capital gain or loss and generally will be long-term capital gain or loss if the Preferred Securities have been held for more than one year at the time of sale. Amounts attributable to accrued interest with respect to a holder's share of the Junior Subordinated Debentures not previously included in income will be taxable as ordinary income.

Should the Corporation exercise its option to defer any payment of interest on the Junior Subordinated Debentures, the Preferred Securities may trade at a price that does not accurately reflect the value of accrued but unpaid interest with respect to the underlying Junior Subordinated Debentures (or OID if the Junior Subordinated Debentures are treated as having been issued with OID). In the event of such a deferral, a holder who disposes of its Preferred Securities will be required to include in ordinary income (i) any portion of the amount realized that is attributable to such accrued but unpaid interest to the extent not previously included in income, or (ii) any amount of OID, in either case, that has accrued on its pro rata share of the underlying Junior Subordinated Debentures during the taxable year of sale through the date of disposition. Any such income inclusion will increase the holder's adjusted tax basis in the Preferred Securities disposed of. To the extent that the amount

52

realized in the sale is less than the holder's adjusted tax basis, a holder will recognize a capital loss. Subject to certain limited exceptions, capital losses cannot be applied to offset ordinary income for United States federal income tax purposes.

BACKUP WITHHOLDING AND INFORMATION REPORTING

The amount of interest paid and any OID accrued on the Preferred Securities held of record by individual citizens or residents of the United States, or certain trusts, estates, and partnerships, will be reported to the Internal Revenue Service on Forms 1099, which forms should be mailed to such holders of Preferred Securities by January 31 following each calendar year. Payments of interest may be subject to a "backup" withholding tax at a rate of 31% unless the holder complies with certain identification and other requirements. Payment of the proceeds from the sale of Preferred Securities may also be subject to information reporting and backup withholding. Any amounts withheld under the backup withholding rules will be allowed as a credit against the holder's United States federal income tax liability, provided the required information is furnished to the Internal Revenue Service.

EFFECT OF PROPOSED CHANGES IN TAX LAWS

In both 1996 and 1997 legislation was proposed that would, if enacted, have adversely affected the tax treatment of the Preferred Securities. On March 19, 1996, President Clinton proposed certain tax law changes (the "1996 Proposed Legislation") that would, among other things, generally deny corporate issuers a deduction for interest in respect of certain debt obligations having a maximum term in excess of 20 years and not shown as indebtedness on the issuer's applicable consolidated balance sheet. Neither the 1996 Proposed Legislation or similar legislation was enacted during the 104th Congress. On February 6, 1997, President Clinton proposed in the administration's fiscal year 1998 budget certain tax law changes (the "Administration's 1997 Tax Proposals") that would, among other things, generally deny corporate issuers a deduction for interest or OID in respect of certain debt obligations having a maximum term in excess of 15 years and not shown as indebtedness on the issuer's applicable consolidated balance sheet. Neither the Administration's 1997 Tax Proposals nor similar legislation was enacted by the 105th Congress. There can be no assurance, however, that legislation enacted after the date hereof will not adversely affect the ability of the Company to deduct the interest payable on the Junior Subordinated Debentures or otherwise give rise to a Tax Event.

THE UNITED STATES FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE MAY NOT BE APPLICABLE DEPENDING UPON A HOLDER'S PARTICULAR SITUATION. HOLDERS SHOULD CONSULT THEIR TAX ADVISOR WITH RESPECT TO THE TAX CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE PREFERRED SECURITIES, INCLUDING THE TAX CONSEQUENCES UNDER STATE, LOCAL, FOREIGN AND OTHER TAX LAWS AND THE POSSIBLE EFFECTS OF CHANGES IN THE UNITED STATES FEDERAL OR OTHER TAX LAWS.

ERISA CONSIDERATIONS

Employee benefit plans that are subject to the Employee Retirement Income Security Act of 1974, as amended ("ERISA"), or Section 4975 of the Code ("Plans"), generally may purchase Preferred Securities, subject to the investing fiduciary's determination that the investment in Preferred Securities satisfies ERISA's fiduciary standards and other requirements applicable to investments by the Plan.

In any case, the Company and/or any of its affiliates may be considered a "party in interest" (within the meaning of ERISA) or a "disqualified person" (within the meaning of Section 4975 of the Code) with respect to certain plans (generally, Plans maintained or sponsored by, or contributed to by, any such persons with respect to which the Company or an affiliate is a fiduciary or Plans for which the Company or an affiliate provides services). The acquisition and ownership of Preferred Securities by a Plan (or by an individual retirement arrangement or other Plans described in Section 4975(e)(1) of the Code) with respect to which the Company or

53

any of its affiliates is considered a party in interest or a disqualified person may constitute or result in a prohibited transaction under ERISA or Section 4975 of the Code, unless such Preferred Securities are acquired pursuant to and in accordance with an applicable exemption.

As a result, Plans with respect to which the Company or any of its affiliates is a party in interest or a disqualified person should not acquire Preferred Securities unless such Preferred Securities are acquired pursuant to and in accordance with an applicable exemption. Any other Plans or other entities whose assets include Plan assets subject to ERISA or Section 4975 of the code proposing to acquire Preferred Securities should consult with their own counsel.

UNDERWRITING

The Underwriters named below, represented by Tucker Anthony Incorporated (the "Representative"), have severally agreed, subject to the terms and conditions set forth in the Underwriting Agreement, the form of which is filed as an exhibit to the Registration Statement of which this Prospectus forms a part, to purchase from the Trust the number of Preferred Securities set forth opposite their respective names below. The several Underwriters have agreed in the Underwriting Agreement, subject to the terms and conditions set forth therein, to purchase all the Preferred Securities offered hereby if any of the Preferred Securities are purchased. In the event of default by an Underwriter, the Underwriting Agreement provides that, in certain circumstances, purchase commitments of the nondefaulting Underwriters may be increased or the Underwriting Agreement may be terminated.

                                                                               Number of Preferred
       Underwriters                                                       Securities
       ------------                                                   -------------------

         Total................................................

The Representative has advised the Trust that it proposes initially to offer the Preferred Securities to the public at the public offering price set forth on the cover page of this Prospectus, and to certain dealers at such price less a concession not in excess of $___ per Preferred Security. The Underwriters may allow, and such dealers may reallow, a discount not in excess of $___ per Preferred Security to certain other dealers. After the initial public offering, the public offering price, concession and discount may be changed.

In view of the fact that the proceeds of the sale of the Preferred Securities will be used to purchase the Junior Subordinated Debentures of the Company, the Underwriting Agreement provides that the Company will pay as compensation to the Underwriters arranging the investment therein of such proceeds, an amount in immediately available funds of $___ per Preferred Security (or $___ in the aggregate) for the accounts of the several Underwriters.

The Trust has granted the Underwriters an option to purchase up to an additional 375,000 Preferred Securities at the public offering price. Such option, which expires 30 days from the date of this Prospectus, may be exercised solely to cover over-allotments. To the extent that the Underwriters exercise such option, each of the Underwriters will have a firm commitment, subject to certain conditions, to purchase approximately the same percentage of the additional Preferred Securities that the number of Preferred Securities to be purchased initially by the Underwriter is of the 2,500,000 Preferred Securities initially purchased by the Underwriters.

To the extent that the Underwriters exercise their option to purchase additional Preferred Securities, the Trust will issue and sell to the Company additional Common Securities in such aggregate Liquidation Amount as is required for the Company to continue to hold Common Securities in an aggregate Liquidation Amount equal

54

to at least 3% of the total capital of the Trust and the Company will issue and sell to the Trust Junior Subordinated Debentures in an aggregate principal amount equal to the total aggregate Liquidation Amount of the additional Preferred Securities being purchased pursuant to the option and the additional Common Securities.

In connection with the offering of the Preferred Securities, the Underwriters and any selling group members and their respective affiliates may engage in transactions effected in accordance with Rule 104 of the Securities and Exchange Commission's Regulation M that are intended to stabilize, maintain or otherwise affect the market price of the Preferred Securities. Such transactions may include over-allotment transactions in which the Underwriters create a short position for their own account by selling more Preferred Securities than they are committed to purchase from the Trust. In such case, to cover all or part of the short position, the Underwriters may exercise the over-allotment option described above or may purchase Preferred Securities in the open market following completion of the initial offering of the Preferred Securities. The Underwriters also may engage in stabilizing transactions in which they bid for, and purchase, Preferred Securities at a level above that which might otherwise prevail in the open market for the purpose of preventing or retarding a decline in the market price of the Preferred Securities. The Underwriters also may reclaim any selling concessions allowed to an Underwriter or dealer if the Underwriters repurchase shares distributed by that Underwriter or dealer. Any of the foregoing transactions may result in the maintenance of a price for the Preferred Securities at a level above that which might otherwise prevail in the open market. Neither the Company nor any of the Underwriters makes any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the Preferred Securities. The Underwriters are not required to engage in any of the foregoing transactions and, if commenced, such transactions may be discontinued at any time without notice.

During a period of 180 days from the date of this Prospectus, neither the Trust nor the Company will, subject to certain exceptions, without the prior written consent of the Representative, directly or indirectly, sell, offer to sell, grant any option for sale of, or otherwise dispose of, any Preferred Securities, any security convertible into or exchangeable into or exercisable for Preferred Securities or Junior Subordinated Debentures or any debt securities substantially similar to the Junior Subordinated Debentures or equity securities substantially similar to the Preferred Securities (except for Junior Subordinated Debentures and the Preferred Securities offered hereby).

Because the National Association of Securities Dealers, Inc. ("NASD") is expected to view the Preferred Securities as interests in a direct participation program, the offering of the Preferred Securities is being made in compliance with the applicable provisions of Rule 2810 of the NASD's Conduct Rules.

Application has been made to have the Preferred Securities approved for quotation on The Nasdaq Stock Market's National Market. The Representative has advised the Trust that it presently intends to make a market in the Preferred Securities after the commencement of trading on The Nasdaq Stock Market's National Market, but no assurances can be made as to the liquidity of such Preferred Securities or that an active and liquid trading market will develop or, if developed, that it will continue. The offering price and distribution rate have been determined by negotiations among representatives of the Company and the Underwriters, and the offering price of the Preferred Securities may not be indicative of the market price following the Offering. The Representative will have no obligation to make a market in the Preferred Securities, however, and may cease market-making activities, if commenced, at any time.

The Trust and the Company have agreed to indemnify the Underwriters against, or contribute to payments that the Underwriters may be required to make in respect of, certain liabilities, including liabilities under the Securities Act.

The following table summarizes the year-to-year changes in the Company's net interest income resulting from fluctuations in interest rates and volume changes in earning assets and interest bearing liabilities. Changes due to rate are the change in rate multiplied by the prior year's volume. Changes due to volume are the change in volume multiplied by the prior year's rate. Changes in volume and rate that cannot be separately identified have been allocated in proportion to the relationship of the absolute dollar amounts of each change.

Net interest income improved in 1997. Interest income was affected positively by higher loan volume and by improvements in the interest earned in most categories of earning assets. Much of the Company's earning assets were repriced to improve their respective returns. Interest expense rose primarily because of a higher level of borrowed funds. Interest income on securities increased primarily because of volume.

ASSET/LIABILITY MANAGEMENT

The Company's asset/liability management objective is to attempt to insulate the balance sheet, and therefore the income statement, from excessive risk due to changes in market interest rates. It is the responsibility of the Company's ALCO committee to establish long-term strategies with respect to interest rate exposure, and to monitor that exposure in relation to present and prospective market interest rates, economic conditions, and balance sheet composition on an on-going basis. Monitoring techniques include gap management and simulation analysis.

The Company attempts to manage its exposure to interest rate risk by closely monitoring the maturities and interest rate sensitivities of its assets and liabilities. The following table measures the extent to which interest-sensitive assets exceed interest-sensitive liabilities (or vice versa) within certain time periods. This "Gap" analysis is one measure of the Company's sensitivity to interest rate fluctuations. A Gap is considered positive when the amount of interest-sensitive assets maturing or repricing within a period exceeds the amount of interest-sensitive liabilities maturing or repricing within that period; a Gap is considered negative when the converse occurs. During a decreasing interest rate environment, a negative Gap would tend to result in an increase in net interest income while a positive Gap would tend to adversely affect net interest income. In a rising interest rate environment, an institution with a positive Gap would generally expect an increase in net interest income, whereas an institution with a negative Gap would generally be expected to experience the opposite result.

The Company's targeted Gap range is +/- 10% within 3 months or less and +/- 10% within 4 to 12 months with a cumulative 1 year Gap at +/- 10%. The table presents categorical balances based on contractual maturities and repricing opportunities. The resulting amounts have been modified to reflect a management adjustment that pertains to NOW and savings accounts. While these core deposit accounts are subject to immediate withdrawal, the management adjustment is based on the fact that interest changes on such accounts have been infrequent and have not coincided with changes in market interest rates. In addition, a management adjustment has been made in the first maturity interval for the uncollected portion of cash and due from banks.

                                                                       Repricing / Maturity Interval Within

Individual loan officers have designated lending authorities established by the Board of Directors, with larger loans requiring a second approval. The Bank has an Executive Committee of the Board of Directors which meets monthly and ratifies or approves all credits above a specified size. In addition, the Company has an Executive Management Committee which meets monthly and monitors the Company's lending policies and practices. The members of the Executive Management Committee are: Marshall M. Sloane, Chairman, President and CEO; George F. Swansburg, Executive Vice President; Jonathan G. Sloane, Senior Vice President; Paul V. Cusick, Jr., Vice President and Treasurer; all of the Company, and Donald H. Lang and William J. Sloboda, both Executive Vice Presidents of the Bank.

The Company's commercial and industrial (C&I) loan customers represent various small and middle market established businesses involved in manufacturing, distribution, retailing and services. Most clients are privately owned with markets that range from local to national in scope. Many of the loans to this segment are secured by liens on corporate assets and the personal guarantees of the principals. The Bank has placed greater emphasis on building its C&I base over the future. The regional economic strength or weakness impacts on the relative risks in this loan category. There is little concentration to any one business sector and loan risks are generally diversified among many borrowers.

Commercial real estate loans are extended to finance various manufacturing, warehouse, light industrial, office, retail and residential properties in the Banks's market area to generally include Eastern Massachusetts and Southern New Hampshire. Loans are normally extended in amounts up to a maximum of 80% of appraised value and normally for terms up to three to five years. Amortization schedules are long term and thus a balloon payment is due at maturity. Under most circumstances, the Bank will offer to re-write or otherwise extend the loan at prevailing interest rates. During recent years, the Bank has emphasized non-residential type owner-occupied properties. This complements the above C&I emphasis placed on the operating business entities and will be continued. The regional economic environment impacts on the risk to both non-residential and residential mortgages. This environment has improved over the recent period. Together the above factors have stabilized many sections of the regional market.

Residential real estate (1-4 family) includes two categories of loans. Approximately $14 million of loans are classified as "Commercial and Industrial" type loans secured by 1-4 family real estate. Primarily, these are small businesses with modest capital or shorter operating histories wherein the collateral mitigates some risk. The collateral position notwithstanding, this category of loans shares similar risk characteristics as the C&I loans. The balance of loans in this category are mostly 1-4 family residential properties located in the Bank's market area. General underwriting criteria are largely the same as FNMA but normally only one or three year adjustable interest rates are used. The Bank does utilize mortgage insurance in order to provide lower down payment products and has provided a "First Time Homebuyer" product to encourage new home ownership. Residential real estate loan volume has declined but nonetheless remains a core consumer product. The regional environment impacts on the risks to this category. In the recent period, the environment has improved, and the market has generally been stable. Declining interest rates could negatively impact the risk on adjustable interest rate loans as they are repriced in the future.

Home equity loans are extended as both first and second mortgages on owner occupied residential properties in the Bank's market area. Loans are underwritten to a maximum loan to value of 75%.

The Bank does intend to maintain a market for construction loans, principally for smaller local residential projects or an owner occupied commercial project. Independent appraisals of the project and the costs are obtained and funds are advanced over the life of the project as inspections of completed work warrant. Individual consumer residential home construction loans are also extended on a similar basis.

Bank officers evaluate the feasibility of construction projects, based on independent appraisals of the project, architects or engineers evaluations of the cost of construction, and other relevant data. At December 31, 1997, the Company was obligated to advance a total of $321 thousand to complete projects under construction.

At December 31, 1997 approximately 44% of the Company's loan portfolio consisted of commercial real estate loans. Construction loans had increased to 2.4 % of the Company's outstanding loans.

At December 31, 1997, the Company's residential mortgage loans amounted to $76.4 million. The Company's consumer loan portfolio amounted to $38.3 million at December 31, 1997, primarily consisting of home equity loans amounting to $19.0 million and personal lines of credit, motor vehicle loans and other installment loans amounting to $19.3 million.

NONPERFORMING ASSETS AND ALLOWANCE FOR POSSIBLE LOAN LOSSES

Loans are placed on nonaccrual status when any payment of principal and/or interest is 90 days or more past due, unless the collateral is sufficient to cover both principal and interest and the loan is in the process of collection. The Company monitors closely the performance of its loan portfolio. In addition to internal loan review, the Company has contracted with an independent organization to review the Company's commercial and commercial real estate loan portfolios. This independent review was performed in each of the past five years. The status of delinquent loans, as well as situations identified as potential problems, are reviewed on a regular basis by senior management and monthly by the Board of Directors of the Bank.

The following table summarizes the Company's nonperforming assets at the dates indicated.

The lower level of nonperforming assets in 1997 resulted from a reduction in new additions to nonperforming assets during the year combined with an improvement in the resolution of nonperforming assets including payments on nonperforming loans and sales of other real estate owned (OREO).

The Company identifies loans renegotiated prior to January 1, 1995 at then below market rates as troubled debt restructurings. Interest income associated with the $3,306,000 of troubled debt restructurings and performing impaired loans at December 31, 1997 amounted to $230,000 for the year then ended. Interest income for the same period would have amounted to $277,000 under the original terms and agreements of the notes. As a result of placing loans on non-accrual status, the Company has foregone $118,000 of interest income during 1997 compared to $172,000 during 1996.

In addition to the above, the Company is monitoring closely $7.7 million of loans on which management is concerned with the ability of the borrowers to perform. The majority of the loans are secured by real estate properties experiencing higher than expected vacancies and lower than expected rental revenue. While the properties are considered to have adequate value to cover the loan balances at December 31, 1997, such values can fluctuate with changes in the economy and the real estate market.

There were no impaired loans with specific reserves at December 31, 1997 and 1996 because, in the opinion of management, none required a specific reserve. All impaired loans have been measured using the fair value of the collateral method.

The following table summarizes the Company's loans past due 90 days or more and still accruing and impaired loans at the dates indicated.

The provision for 1997, while below the prior four year average, remains above historical levels and reflects significant improvements in the loan portfolio. At December 31, 1997 nonperforming assets were $2.7 million or .86% of loans and related assets. Such figures are significantly lower than those at the end of the last four years.

While the Company expects a similar level of charge-offs in future periods, the pace of the charge-offs depends on many factors including the national and regional economy. Cyclical lagging factors may result in charge-offs being higher than historical levels.

The allowance for loan losses is an estimate of the amount needed for an adequate reserve to absorb losses in the existing loan portfolio. This amount is determined by an evaluation of the loan portfolio including input from an independent organization engaged to review selected larger loans, a review of loan loss experience and current economic conditions. At December 31, the allowance was comprised of the following components.

Obligations of states and political subdivisions consist primarily of obligations of the Commonwealth of Massachusetts and entities within it having other relationships with the Company. The Company regularly bids on tax anticipation notes and other short-term instruments of municipalities who have depository relationships with it. The Company also writes equipment leases to finance acquisition of computers, fire trucks, snow plows and other equipment used by municipalities.

Except for obligations of the United States Government, the portfolio at December 31, 1997 did not include securities of any single issuer in an amount in excess of 10% of stockholders' equity.

DEPOSITS

The Company offers savings accounts, NOW accounts, demand deposits, certificates of deposit and money market accounts. The Company offers cash management accounts which provide either automatic transfer of funds above a specified level from the customer's checking account to a money market account or short-term borrowings. Also, an account reconciliation service is offered whereby the Company provides a computerized report balancing the customer's checking account.

Interest rates on deposits are set weekly by the Treasurer, based on factors including loan demand, maturities and a review of competing interest rates offered. Interest rate policies are reviewed periodically by the Executive Management Committee.

The following table shows the average amount of and average interest rate paid on various categories of deposits during the years indicated.

Total deposits at December 31, 1997 amounted to $515 million, including $63 million of time deposits of $100,000 or more. Traditionally, the Company experiences a decline in deposits during the first and third quarters of each year because of the deposit cycles of certain of its customers, notably municipalities.

The Company's time certificates of deposit in amounts of $100,000 or more at December 31, 1997 mature as follows.

OTHER SERVICES

In addition to fees derived from traditional banking activities such as loan origination fees, the Company derives revenues from its automated lock box collection system and full service securities brokerage offered through Commonwealth Equity Services, Inc., a registered securities broker-dealer and investment adviser.

Under the lock-box program, which is not tied to extensions of credit by the Company, the Company's customer arranges for payments of its accounts receivable to be made directly to the Company. The Company records on its computer the amounts paid to its customers, deposits the funds to the customer's account with the Company and provides computerized records of the amounts received to the Company's customers. Typical customers for the lock box service are municipalities who use it to automate tax collections, cable TV companies, and other commercial enterprises.

EMPLOYEES

As of December 31, 1997, the Company had 201 full-time and 85 part-time employees. The Company's employees are not represented by any collective bargaining unit. The Company believes that its employee relations are good.

HOLDING COMPANY REGULATION

The Company is a bank holding company as defined by the Bank Holding Company Act of 1956, as amended (the "Holding Company Act") and is registered as such with the Federal Reserve Board (the "FRB"), which is responsible for administration of the Holding Company Act. As required by the Holding Company Act, the Company files with the FRB an annual report regarding its financial condition and operations, management and intercompany relationships of the Company and the Bank. It is also subject to examination by the FRB and must obtain FRB approval before (I) acquiring direct or indirect ownership or control of more than 5% of the voting stock of any bank, unless it already owns or controls a majority of the voting stock of that bank, (ii) acquiring all or substantially all of the assets of a bank, except through a subsidiary which is a bank, or (iii) merging or consolidating with any other bank holding company. A bank holding company must also give the FRB prior written notice before purchasing or redeeming its equity securities if the gross consideration for the purchase or redemption, when aggregated with the net consideration paid by the company for all such purchases or redemptions during the preceding 12 months, is equal to 10% or more of the Company's consolidated net worth.

The Holding Company Act prohibits a bank holding company, with certain exceptions, from (I) acquiring direct or indirect ownership or control of any voting shares of any company which is not a bank or a bank holding company, or
(ii) engaging in any activity other than managing or controlling banks, or furnishing services to or performing services for its subsidiaries. A bank holding company may own, however, shares of a company engaged in activities which the FRB has determined are so closely related to banking or managing or controlling banks as to be a proper incident thereto. Such activities include leasing real or personal property under certain conditions; operating as a mortgage finance or factoring company; servicing loans and other extensions of credit; acting as a fiduciary; acting as investment or financial advisor under certain conditions; acting as insurance agent or broker principally in connection with extension of credit by the bank holding company or any subsidiary; acting as underwriter for credit life insurance and credit accident and health insurance which is directly related to extension of credit by the bank holding company or any subsidiary; arranging commercial real estate equity financing under certain circumstances; providing securities brokerage and related services as agent for the account of customers; providing bookkeeping or data processing services for the bank holding company, its affiliates and other institutions, with certain limitations; making certain equity and debt investments in community rehabilitation and development corporations; and providing certain kinds of management consulting advice to unaffiliated banks.

A bank holding company and its subsidiaries are prohibited from acquiring any voting shares of, interest in, or all or substantially all of the assets of, any bank located outside the state in which the operations of the bank holding company's banking subsidiaries are principally conducted, unless the acquisition is specifically authorized by the statutes of the state in which the bank to be acquired is located.

The Company and its subsidiaries are examined by federal and state regulators. The FRB has responsibility for holding company activities and performed a review in 1997.

The regulatory standard for capital adequacy assigns risk factors to asset categories and certain off-balance sheet commitments. The fully-phased in 1992 standard requires a tier-1 capital to risk assets ratio of 4.00% and a total capital to risk assets ratio of 8.00%. At December 31, 1997, the Company's ratios were 15.51% and 16.76%, respectively. The Bank also exceeded these risk-weighted capital measures at December 31, 1997. In addition to these risk based capital requirements, federal banking regulators have leverage guidelines. The minimum leverage requirement is 4% as measured by the ratio of core capital, net of intangible assets, to total assets. At December 31, 1997 the Company's ratio was 9.09%. The Bank also exceeded the leverage requirement at December 31, 1997.

FEDERAL DEPOSIT INSURANCE CORPORATION IMPROVEMENT ACT OF 1991

On December 19, 1991, the FDIC Improvement Act of 1991 (the "1991 Act") was enacted. This legislation seeks to recapitalize the Bank Insurance Fund of the FDIC ("BIF") so that the BIF can continue to resolve its caseload of failed banks. The recapitalization will be funded through, among other things, increased deposit insurance assessments payable by BIF-insured institutions, which will increase the cost of doing business by all BIF-insured institutions, including the Company's subsidiary. The 1991 Act also provides for, among other things: enhanced federal supervision of depository institutions, including greater authority for the appointment of a conservator or receiver for undercapitalized institutions; the establishment of risk-based deposit insurance premiums; a requirement that the federal banking agencies amend their risk-based capital requirements to include components for interest-rate risk, concentration of credit risk, and the risk of nontraditional activities; expanded authority for cross-industry mergers and acquisitions; mandated consumer protection disclosures with respect to deposit accounts; and imposed restrictions on the activities of state-chartered banks, including the Company's subsidiary.

Provisions of the 1991 Act relating to the activities of state-chartered banks may significantly impact the way the Company conducts its business. In this regard, the 1991 Act provides that, effective one year from date of enactment, insured state banks, such as the Company's subsidiary, may not engage as principal in any activity that is not permissible for a national bank, unless the FDIC has determined that the activity would pose no significant risk to the BIF and the state bank is in compliance with applicable capital standards. Activities of subsidiaries of insured state banks are similarly restricted to those activities permissible for subsidiaries of national banks, unless the FDIC has determined that the activity would pose no significant risk to the BIF and the state bank is in compliance with applicable capital standards.

COMPETITION

The Company experiences substantial competition in attracting deposits and making loans from commercial banks, thrift institutions and other enterprises such as insurance companies and mutual funds. These competitors include several major commercial banks whose greater resources may afford them a competitive advantage by enabling them to maintain numerous branch offices and mount extensive advertising campaigns.

ITEM 2. PROPERTIES

The Company owns its main banking office, headquarters, and operations center in Medford, and 11 of the 14 other facilities in which its branch offices are located. The remaining offices are occupied under leases expiring on various dates from 1997 to 2026. The Company has renovated its Medford operations center to provide space for its Executive and Lending staff.

ITEM 3. LEGAL PROCEEDINGS

The Company and its subsidiaries are parties to various claims and lawsuits arising in the course of their normal business activities. Although the ultimate outcome of these suits cannot be ascertained at this time, it is the opinion of management that none of these matters, when resolved, will have a material adverse effect on the Company's consolidated financial position.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

No matters were submitted to a vote of Security Holders during the fourth quarter of the fiscal year ended December 31, 1997.

PART II

ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS

(a) The Class A Common Stock of the Company is traded on the NASDAQ system. The price range of the Company's common stock since January 1, 1996 is shown on page 19.

The shares of Class A Common Stock are not entitled to vote in the election of Company Directors but, in limited circumstances, are entitled to vote as a class on certain extraordinary transactions, including any merger or consolidation (other than one in which the Company is the surviving corporation or one which by law may be approved by the directors without any stockholder vote) or the sale, lease, or exchange of all or substantially all of the property and assets of the Company. Since the vote of a majority of the shares of Class B Common Stock, voting as a class, is required to approve certain extraordinary corporate transactions, the Board of Directors of the Company has power to prevent any takeover of the Company not approved by them in their capacity as Class B stockholders.

(b)      Approximate number of equity security holders as of December
         31, 1997.

                                            Approximate Number

As a bank holding company, the Company's ability to pay dividends is dependent in part upon the dividend payments it receives from the Bank, which are subject to certain restrictions on the payment of dividends. A Massachusetts trust company may pay dividends out of net profits from time to time, provided that either (I) the trust company's capital stock and surplus account equal an aggregate of at least 10% of its deposit liability, or (ii) the amount of its surplus account is equal to at least the amount of its capital account.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND
FINANCIAL CONDITION

OVERVIEW

Century Bancorp, Inc. (the "Company") had net income of $6,823,000 for the year ended December 31, 1997, compared with net income of $5,434,000 for year ended December 31, 1996 and net income of $4,574,000 for the year ended December 31, 1995. Basic earnings per share were $1.18 in 1997 compared to $0.95 in 1996 and $0.80 in 1995. Diluted earnings per share were $1.17 in 1997 compared to $0.94 in 1996 and $0.79 in 1995.

Total assets were $631,125,000 at December 31, 1997, an increase of 12.5% from total assets of $560,857,000 on December 31, 1996, which, in turn, were 5.4% higher than total assets of $531,928,000 on December 31, 1995.

On December 31, 1997, stockholders' equity totaled $53,857,000 compared with $47,489,000 on December 31, 1996, and $42,935,000 on December 31, 1995. Book value increased to $9.30 at December 31, 1997 from $8.25 on December 31, 1996, which had increased from $7.50 on December 31, 1995.

On December 10, 1997 the Company announced an agreement to merge Haymarket Cooperative Bank, based in Boston, Massachusetts, into Century Bank and Trust Company. The agreement called for the Bank to acquire assets of approximately $142 million and operate two banking offices located in Boston. Century Bank and Trust Company will pay approximately $20 million in cash for Haymarket Cooperative Bank and is subject to federal and state regulatory approval. The transaction will be accounted for using the purchase method of accounting.

During 1997 the Company conducted a comprehensive review of its computer systems to identify the systems that could be affected by the "Year 2000" issue and has developed an implementation plan to resolve the issue. The Year 2000 problem is the result of computer programs being written using two digits rather than four to define the applicable year. Any of the Company's programs that have time-sensitive software may recognize a date using "00" as the year 1900 rather then the year 2000. This could result in a major system failure or miscalculations. The Company presently believes that, with the previously planned conversion to a new core processing software and modifications to existing software, the Year 2000 problem will not pose significant operational problems for the Company's computer systems as so modified and converted. The new core processing software is Year 2000 compliant and the other systems which require modifications are not significant and the cost is not material. However, if such modifications and conversions are not completed timely, the Year 2000 problem may have a material impact on the operations of the Company.

RESULTS OF OPERATIONS

The Company's operating results depend primarily on net interest income and fees received for providing services. Net interest income on a fully taxable equivalent basis increased 10.0% in 1997 to $25,448,000 compared with $23,132,000 in 1996. Interest income was affected positively by improvements in the interest earned in most categories of earning assets. Much of the Company's earning assets were repriced to improve their respective returns. Net interest income is affected by the level of interest rates, the ability of the Company's earning assets and deposits to adjust to changes in interest rates and the mix of the Company's earning assets and deposits. The net yield on earning assets on a fully taxable equivalent basis increased to 4.99% in 1997 from 4.79% in 1996 which, in turn, had decreased from 4.86% in 1995.

Average earning assets were $510,028,000 in 1997, an increase of $26,919,000 or 5.6% from the average in 1996, which was 9.1% higher than the average in 1995. Total average securities, including securities available for sale and securities held to maturity, increased 3.7% to $192,887,000. The increase in securities volume combined with a slight lengthening in the maturity of the portfolios resulted in higher securities income, which increased 4.1% to $12,156,000. Total average loans increased 7.9% to $304,147,000 after increasing $2,388,000 in 1996. The increase in loan volume combined with a slightly higher level of interest rates resulted in higher loan income, which increased by 7.8% or $2,062,000 to $28,353,000. Total loan income was $26,326,000 in 1995.

The Company's sources of funds include deposits and borrowed funds. On average, deposits showed an increase of 1.6% in 1997 after increasing by 8.3% in 1996. Borrowed funds increased by 66.3% in 1997 following an increase of 28.9% in 1996. The majority of the Company's borrowed funds are in repurchase agreements. Interest expense totaled $15,922,000 in 1997, an increase of $117,000 or .7% from 1996 when interest expense increased 7.6% from 1995. This increase in interest expense is due primarily to an increase in deposits and borrowed funds volume.

PROVISION FOR LOAN LOSS

The provision for loan losses was $660,000 in 1997 compared with $1,020,000 in 1996 and $1,560,000 in 1995. These provisions are the result of management's evaluation of the quality of the loan portfolio considering such factors as loan status, collateral values, financial condition of the borrower, the state of the economy and other relevant information.

The allowance for loan losses was $4,446,000 at December 31, 1997 compared with $4,179,000 at December 31, 1996 and $4,193,000 at December 31, 1995. Expressed as a percentage of outstanding loans at year-end, the allowance was 1.41% in 1997, 1.45% in 1996 and 1.47% in 1995.

Management believes that the allowance for loan losses is adequate. Management uses available information to provide for losses but recognizes that changes in economic conditions may result in additional losses and additional loss provisions. Also, the allowance is reviewed in conjunction with regulatory examinations. These reviews may require the Company to make additional provisions to the allowance based on judgements made by the regulators.

The Company experienced a decrease in net charge-offs in 1997 with net charge-offs as a percent of average loans outstanding at 0.13%. The comparable figures for 1996 and 1995 were 0.37% and 0.57% respectively. Non-performing loans, which include all non-accruing loans and certain restructured, accruing loans, totaled $2,731,000 on December 31, 1997, compared with $3,304,000 on December 31, 1996.

OTHER OPERATING INCOME

The Company continued to experience good results in its fee-based services in 1997. These fee-based services include deposit related services, lock-box processing, mortgage origination services and securities brokerage services.

Total other operating income in 1997, was $4,994,000 an increase of $233,000 or 4.9% compared to 1996. This increase followed an increase of $39,000 or 0.8% in 1996, compared to 1995. Service charge income, which continues to be the largest area of other operating income with $1,791,000 in 1997, saw an increase of $164,000 in 1997 as more customers paid demand deposit fees. Lock-box revenues totaled $1,467,000 up $187,000 in 1997, primarily as a result of an increase in the lock-box customer base. Brokerage commissions increased slightly to $1,171,000 in 1997 from $1,072,000 in 1996, which, saw an increase of $45,000 from 1995. Gain on sale of loans decreased to $136,000 in 1997 from $290,000 in 1996 and $217,000 in 1995. There were no security transactions in 1997, 1996 and 1995.

OPERATING EXPENSES

Total operating expenses excluding other real estate owned (OREO) expenses and writedowns were $18,578,000 in 1997 compared to $17,894,000 in 1996 and $18,007,000 in 1995. Total OREO expenses were $22,000 in 1997, $(20,000) in 1996 and $217,000 in 1995. At year-end the Company had $0 of OREO compared with $182,000 at December 31, 1996.

Salaries and employee benefits expenses increased by $379,000 or 3.2% in 1997 after increasing 3.0% in 1996. Nearly all of the increase, for 1997 and 1996, was in the salaries category and was caused by an increase in the wage base.

Occupancy expense decreased by $50,000 or 3.8% in 1997 primarily because of an increase in tenant rents. Occupancy expense decreased by 6.4% in 1996 primarily because of a decrease in building depreciation. Equipment expense increased by $5,000 in 1997 primarily because of increased equipment depreciation. Equipment expense increased by $54,000 in 1996 also because of increased equipment depreciation.

Other operating expenses increased by $350,000 in 1997, which followed a $423,000 decrease in 1996. In 1997 increases were primarily the result of increased marketing, FDIC insurance and other operating expenses. In 1996 decreases in FDIC insurance expense and legal expense were offset by increased marketing and amortization of the core deposit intangible associated with a prior branch acquisition.

22

PROVISION FOR INCOME TAXES

Income tax expense was $4,205,000 in 1997, $3,405,000 in 1996 and $1,666,000 in 1995. The relatively low tax expense for 1995 is a result of reductions in the valuation reserve for deferred income taxes. The effective tax rate was 38.1% in 1997, 38.5% in 1996 and 26.7% in 1995.

MARKET RISK AND ASSET LIABILITY MANAGEMENT

Market risk is the risk of loss from adverse changes in market prices and rates. The Company's market risk arises primarily from interest rate risk inherent in its lending and deposit taking activities. To that end, management actively monitors and manages its interest rate risk exposure.

The Company's profitability is affected by fluctuations in interest rates. A sudden and substantial increase in interest rates may adversely impact the Company's earnings to the extent that the interest rates borne by assets and liabilities do not change at the same speed, to the same extent, or on the same basis. The Company monitors the impact of changes in interest on its net interest income using several tools. One measure of the Company's exposure to differential changes in interest rates between assets and liabilities is shown in the Company's gap table shown below. Another measure is an interest rate risk management test. This test measures the impact on net interest income of an immediate change in interest rates in 100 basis point increments.

--------------------------------------------------------------------------------------------
Change in Interest Rates (in Basis Points)      Percentage Change in Net Interest Income (1)
--------------------------------------------------------------------------------------------
                   +200                                             5.1%
                   +100                                             2.5%
                   -100                                            (2.0%)
                   -200                                            (3.8%)

(1) The percentage change in this column represents net interest income for 12 months in a stable interest rate environment versus the Net Interest Income in the various rate scenarios.

The Company's primary objective in managing interest rate risk is to minimize the adverse impact of changes in interest rates on the Company's net interest income and capital, while structuring the Company's asset-liability structure to obtain the maximum yield-cost spread on that structure. The Company relies primarily on its asset-liability structure to control interest rate risk.

The Company manages the mix, maturity and pricing of its assets and liabilities so that changes in interest rates will not impact earnings adversely. The interest rate gap is used to measure the Company's exposure. At December 31, 1997 the gap was:

====================================================================================

LIQUIDITY

Liquidity is provided by maintaining an adequate level of liquid assets that include cash and due from banks, federal funds sold and other temporary investments. Liquid assets totaled $97,892,000 on December 31, 1997 compared with $67,681,000 on December 31, 1996, and $51,114,000 on December 31, 1995. In each of the three years deposit activity has generally been adequate to support asset activity.

The source of funds for dividends paid by the Company is dividends received from the Bank. The Company and the Bank are regulated enterprises and their abilities to pay dividends are subject to regulatory review and restriction. Certain regulatory and statutory restrictions exist regarding dividends, loans and advances from the Bank to the Company. Generally, the Bank has the ability to pay dividends to the Company subject to minimum regulatory capital requirements.

23

CAPITAL ADEQUACY

Total stockholders' equity was $53,857,000 at December 31, 1997, compared with $47,489,000 at December 31, 1996 and $42,935,000 at December 31, 1995. The increases in all years reported were primarily the result of retained earnings less dividends paid, although there was a $123,000 increase in 1997, a $133,000 increase in 1996 and a $6,000 increase in 1995 from the execution of certain stock options.

Federal banking regulators have issued risk-based capital guidelines which assign risk factors to asset categories and off-balance sheet items. The current guidelines require a tier-1 capital-to-risk assets ratio of 4.00% and a total capital-to-risk assets ratio of 8.00%. The Company and the Bank exceeded these requirements with a tier-1 capital-to-risk assets ratio of 15.51% and 13.38% respectively, and total capital-to-risk assets ratio of 16.76% and 14.64%, respectively at December 31, 1997. Additionally, federal banking regulators have issued leverage ratio guidelines which supplement the risk-based capital guidelines. The minimum leverage ratio requirement applicable to the Company is 4.00% and at December 31, 1997, the Company and the Bank exceeded this requirement with leverage ratios of 9.09% and 7.85%, respectively.

RECENT ACCOUNTING DEVELOPMENTS

In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive Income." SFAS No. 130 establishes standards for reporting and displaying comprehensive income, which is defined as all changes to equity except investments by and distributions to shareholders. Net income is a component of comprehensive income, with all other components referred to in the aggregate as other comprehensive income. This statement is effective for 1998 financial statements.

Also in June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of an Enterprise and Related Information," which establishes standards for reporting information about operating segments. An operating segment is defined as a components of a business for which separate financial information is available that is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and evaluate performance.

This statement requires a company to disclose certain income statement and balance sheet information by operating segment, as well as provide a reconciliation of operating segment information to the company's consolidated balances. This statement is effective for 1998 annual financial statements.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The consolidated financial statements include the accounts of Century Bancorp, Inc. (the "Company") and its wholly-owned subsidiary, Century Bank and Trust Company (the "Bank"). The Company provides a full range of banking services to individual, business and municipal customers in Massachusetts. As a bank holding company, the Company is subject to the regulation and supervision of the Federal Reserve Board. The Bank, a state chartered financial institution, is subject to supervision and regulation by applicable state and federal banking agencies, including the Federal Reserve Board, the Office of the Comptroller of the Currency (the "Comptroller"), the Federal Deposit Insurance Corporation (the "FDIC") and the Commonwealth of Massachusetts Commissioner of Banks. The Bank is also subject to various requirements and restrictions under federal and state law, including requirements to maintain reserves against deposits, restrictions on the types and amounts of loans that may be granted and the interest that may be charged thereon, and limitations on the types of investments that may be made and the types of services that may be offered. Various consumer laws and regulations also affect the operations of the Bank. In addition to the impact of regulation, commercial banks are affected significantly by the actions of the Federal Reserve Board as it attempts to control the money supply and credit availability in order to influence the economy. All aspects of the Company's business are highly competitive. The Company faces aggressive competition from other lending institutions and from numerous other providers of financial services.

BASIS OF FINANCIAL STATEMENT PRESENTATION

The financial statements have been prepared in conformity with generally accepted accounting principles and to general practices within the banking industry. In preparing the financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and revenues and expenses for the period. Actual results could differ from those estimates.

Material estimates that are susceptible to change in the near-term relate to the allowance for losses on loans. Management believes that the allowance for losses on loans is adequate based on independent appraisals and review of other factors associated with the assets. While management uses available information to recognize losses on loans, future additions to the allowance for loans may be necessary based on changes in economic conditions. In addition, regulatory agencies periodically review the Company's allowance for losses on loans. Such agencies may require the Company to recognize additions to the allowance for loans based on their judgements about information available to them at the time of their examination.

INVESTMENT SECURITIES

Debt securities that the Company has the positive intent and ability to hold to maturity are classified as held-to-maturity and reported at amortized cost; debt and equity securities that are bought and held principally for the purpose of selling are classified as trading and reported at fair value, with unrealized gains and losses included in earnings; and debt and equity securities not classified as either held-to-maturity or trading are classified as available-for-sale and reported at fair value, with unrealized gains and losses excluded from earnings and reported as a separate component of stockholders' equity, net of estimated related income taxes. The Company has no securities held for trading.

Premiums and discounts on investment securities are amortized or accreted into income by use of the level-yield method. If a decline in fair value below the amortized cost basis of an investment is judged to be other than temporary, the cost basis of the investment is written down to fair value. The amount of the writedown is included as a charge to earnings. Gains and losses on the sale of investment securities are recognized at the time of sale on a specific identification basis.

LOANS

Interest on loans is recognized based on the daily principal amount outstanding. Accrual of interest is discontinued when loans become 90 days delinquent unless the collateral is sufficient to cover both principal and interest and the loan is in the process of collection. Loans, including impaired loans, on which the accrual of interest has been discontinued are designated non-accrual loans. When a loan is placed on non-accrual, all income which has been accrued but remains unpaid is reversed against current period income and all amortization of deferred loan fees is discontinued. Non-accrual loans may be returned to an accrual status when principal and interest payments are not delinquent and the risk characteristics of the loan have improved to the extent that there no longer exists a concern as to the collectibility of principal and income. Income received on non-accrual loans is either recorded in income or applied to the principal balance of the loan depending on management's evaluation as to the collectibility of principal.

Loans held for sale are carried at the lower of aggregate cost or market value. Gain or loss on sales of loans is recognized at the time of sale when the sales proceeds exceed or are less than the Bank's investment in the loans. Additionally, gains and losses are recognized when the average interest rate on the loans sold, adjusted for normal servicing fee, differs from the agreed yield to the buyer. The resulting excess service fee receivables, if any, are amortized using the interest method over the estimated life of the loans, adjusted for estimated prepayments.

Discounts and premiums on loans purchased from failed financial institutions that represent market yield adjustments are accreted or amortized to interest income over the estimated lives of the loans using the level-yield method.

Loan origination fees and related direct incremental loan origination costs are offset and the resulting net amount is deferred and amortized over the life of the related loans using the level-yield method.

The Bank accounts for impaired loans, except those loans that are accounted for at fair value or at lower of cost or fair value, at the present value of the expected future cash flows discounted at the loan's effective interest rate. This method applies to all loans, uncollateralized as well as collateralized, except large groups of smaller-balance homogeneous loans that are collectively evaluated for impairment, loans that are measured at fair value and leases and debt securities. Management considers the payment status, net worth and earnings potential of the borrower, and the value and cash flow of the collateral as factors to determine if a loan will be paid in accordance with its contractual terms. Management does not set any minimum delay of payments as a factor in reviewing for impaired classification. Impaired loans are charged-off when management believes that the collectibility of the loan's principal is remote. In addition, criteria for classification of a loan as in-substance foreclosure has been modified so that such classification need be made only when a lender is in possession of the collateral. The Bank measures the impairment of troubled debt restructurings using the pre-modification rate of interest.

The Bank recognizes the rights to service mortgage loans for others as an asset, including rights acquired through both purchases and originations. Capitalized mortgage servicing rights are amortized over the period of estimated net servicing income and are periodically evaluated for impairment based on their fair value.

Effective January 1, 1997, the Bank adopted SFAS No. 125, "Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities." This statement provides accounting and reporting standards for transfers and servicing of financial assets and extinguishments of liabilities based on consistent application of a financial-components approach that focuses on control. It distinguishes transfers of financial assets that are sales from transfers that are secured borrowings. Under the financial-components approach, after a transfer of financial assets, an entity recognizes all financial and servicing assets it controls and liabilities it has incurred and derecognizes financial assets it no longer controls and liabilities that have been extinguished. The financial-components approach focuses on the assets and liabilities that exist after the transfer. Many of these assets and liabilities are components of financial assets that existed prior to the transfer. If a transfer does not meet the criteria for a sale, the transfer is accounted for as a secured borrowing with a pledge of collateral. However, SFAS No. 127, "Deferral of the Effective Date of Certain Provisions of SFAS No. 125," requires the deferral of implementation as it relates to repurchase agreements, dollar-rolls, securities lending and similar transactions until after December 31, 1997. Earlier or retroactive applications of this statement is not permitted. The Company has determined that the adoption of SFAS No. 127 will not have a material impact on its consolidated financial statements. The adoption of SFAS No. 125 did not have a significant impact.

ALLOWANCE FOR LOAN LOSSES

The allowance for loan losses is based on management's evaluation of the quality of the loan portfolio and is used to provide for losses resulting from loans which ultimately prove uncollectible. In determining the level of the allowance, periodic evaluations are made of the loan portfolio which take into account such factors as the character of the loans, loan status, financial posture of the borrowers, value of collateral securing the loans and other relevant information sufficient to reach an informed judgement. The allowance is increased by provisions charged to income and reduced by loan charge-offs, net of recoveries.

30

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

While management uses available information in establishing the allowance for loan losses, future adjustments to the allowance may be necessary if economic conditions differ substantially from the assumptions used in making the evaluations. Loans are charged-off in whole or in part when, in management's opinion, collectibility is not probable.

Management believes that the allowance for loan losses is adequate. In addition, various regulatory agencies, as part of their examination process, periodically review the Company's allowance for loan losses. Such agencies may require the Company to recognize additions to the allowance based on their judgements about information available to them at the time of their examination.

OTHER REAL ESTATE OWNED

Other real estate owned ("OREO") includes real estate acquired by foreclosure and real estate substantively repossessed. Real estate acquired by foreclosure is comprised of properties acquired through foreclosure proceedings or acceptance of a deed in lieu of foreclosure. Real estate substantively repossessed includes only those loans for which the Company has taken possession of the collateral, but has not completed legal foreclosure proceedings. Both in-substance foreclosures and real estate formally acquired in settlement of loans are recorded at the lower of the carrying value of the loan or the fair value of the property constructively or actually received. Loan losses from the acquisition of such properties are charged against the allowance for loan losses. After foreclosure, if the fair value of an asset minus its estimated cost to sell is less than the carrying value of the asset, such amount is recognized as a valuation allowance. If the fair value of an asset less its estimated cost to sell subsequently increases so that the resulting amount is more than the asset's current carrying value, the valuation allowance is reversed by the amount of the increase. Increases or decreases in the valuation allowance are charged or credited to income. Gains upon disposition of OREO are reflected in the statement of income as realized. Realized losses are charged to the valuation allowance.

BANK PREMISES AND EQUIPMENT

Bank premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation is computed using the straight-line method over the estimated useful lives of the assets or the terms of leases, if shorter. It is general practice to charge the cost of maintenance and repairs to operations when incurred; major expenditures for improvements are capitalized and depreciated.

INCOME TAXES

The Company uses the asset and liability method of accounting for income taxes. Under the asset and liability method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which temporary differences are expected to be recovered or settled. Under this method, the effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

2. CASH AND DUE FROM BANKS

The Company is required to maintain a portion of its cash and due from banks as a reserve balance under the Federal Reserve Act. Such reserve is calculated based upon deposit levels and amounted to $471,000 at December 31, 1997 and $10,768,000 at December 31, 1996.

5. LOANS

The Company's lending activities are conducted principally in Massachusetts. The Company grants single and multi-family residential loans, commercial and commercial real estate loans, and a variety of consumer loans. To a lesser extent, the Company grants loans for the construction of residential homes, multi-family properties, commercial real estate properties, and land development. Most loans granted by the Company are secured by real estate collateral. The ability and willingness of commercial real estate, commercial, construction, residential and consumer loan borrowers to honor their repayment commitments is generally dependent on the health of the real estate market in the borrowers' geographic areas and the general economy.

12. STOCKHOLDERS' EQUITY

DIVIDENDS

Holders of the Class A common stock may not vote in the election of directors, but may vote as a class to approve certain extraordinary corporate transactions. Class A common stockholders are entitled to receive dividends per share equal to at least 200% per share of that paid, if any, on each share of Class B common stock. Class A common stock is publicly traded. Class B common stock is not publicly traded, however, it can be converted on a share for share basis to Class A common stock at any time. Dividend payments by the Company are dependent in part on the dividends it receives from its bank subsidiary, which are subject to certain regulatory restrictions.

EARNINGS PER SHARE

In February 1997, the FASB issued SFAS No. 128, "Earnings per Share," which is effective for financial statements for both interim and annual periods ending December 31, 1997. Primary EPS has been replaced with basic EPS and fully diluted EPS has been replaced with diluted EPS. Diluted EPS includes the dilutive effect of common stock equivalents; basic EPS excludes all common stock equivalents. Diluted EPS is very similar to fully diluted EPS. The statement also requires a reconciliation of basic EPS to diluted EPS. The only common stock equivalents for the Company are the stock options discussed below. The dilutive effect of these stock options for 1997, 1996 and 1995 was an increase of 58,775, 82,712 and 108,396 shares, respectively.

STOCK OPTION PLAN

On March 10, 1987, the common stockholders of the Company approved a stock option plan (the "Option Plan") that provides for granting of options for not more than 150,000 shares of Class A common stock. Under the Option Plan, all officers and other key employees of the Company are eligible to receive non-qualified and incentive stock options to purchase shares of Class A common stock. The Option Plan is administered by the Compensation Committee

35

whose members are ineligible to participate in the Option Plan. Based on management's recommendations, the Committee submits its recommendations to the Board of Directors as to persons to whom options are to be granted, the number of shares to be granted to each, the option price (which may not be less than 85% of the fair market value for non-qualified stock options, or the fair market value for incentive stock options, of the shares on the date of grant) and the time period over which the options are exercisable (no more than ten years from the date of grant). Options exercisable at December 31, 1997 totaled 78,533 with a weighted average option price of $3.75.

Information with regard to the stock option plan is as follows:

The Company measures compensation cost for stock-based compensation plans using the intrinsic value based method prescribed by Accounting Principles Board Opinion No. 25. The Company granted no stock options during 1997, 1996 or 1995 and, therefore, no disclosures of proforma net income and earnings per share as if the fair value method had been applied are required. The new disclosures will be provided when additional stock options are granted.

CAPITAL AND OTHER REGULATORY REQUIREMENTS

The Bank is subject to various regulatory requirements administered by federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory- and possibly additional discretionary-actions by regulators that, if undertaken, could have a direct material affect on the Company's financial statements. Under capital adequacy guidelines and regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of the Bank's assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. The Bank's capital amounts and classification are also qualitative judgments by the regulators about components, risk weightings, and other factors.

Quantitative measures established by regulation to ensure capital adequacy require the Bank to maintain minimum amounts and ratios (set forth in the table below) of total and Tier I capital (as defined in the regulations) to risk weighted assets (as defined), and Tier I capital (as defined) to average assets (as defined). Management believes, as of December 31, 1997 that the Bank meets all capital adequacy requirements to which it is subject.

As of December 31, 1997, the most recent notification from the FDIC categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, the Bank must maintain minimum total risk-based, Tier I risk-based, and Tier I leverage ratios as set forth in the table. There are no conditions or events since that notification that management believes would cause a change in the Bank's categorization.

Management believes that it is more likely than not that the net deferred income tax asset of $2,235,000 at December 31, 1997 will be realized. The federal tax portion of $1,622,000 of the deferred tax asset is supported by the availability of federal income taxes paid in prior carryback years.

The valuation reserve was reduced by $300,000 in 1996 in recognition of the operating results achieved and the increase in recoverable federal income taxes paid in prior years.

The plan is voluntary and participants are required to contribute to its cost. Under the plan, each participant will receive a retirement benefit based on compensation and length of service. Individual life insurance policies are purchased covering the life of each participant. The Company is the owner of these policies and each participating employee has received an assignment of a portion of each policy's proceeds. The amount of pension liability recorded on the books of the Company related to the supplemental retirement plan was $3.9 million and $3.2 million on December 31, 1997 and 1996, respectively. The net cost to the Company for this plan for the years ended December 31, 1997, 1996 and 1995 was $558,000, $306,000 and $247,000, respectively.

The Company does not offer any post retirement benefits other than pensions.

15. COMMITMENTS AND CONTINGENCIES

A number of legal claims against the Bank arising in the normal course of business were outstanding at December 31, 1997. Management, after reviewing these claims with legal counsel, is of the opinion that their resolution will not have a material adverse affect on the Company's consolidated financial position.

16. FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK

The Company is party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments primarily include commitments to originate and sell loans, standby letters of credit, unused lines of credit and unadvanced portions of construction loans. The instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated balance sheet. The contract or notional amounts of those instruments reflect the extent of involvement the Company has in these particular classes of financial instruments.

The Company's exposure to credit loss in the event of non-performance by the other party to the financial instrument for loan commitments and standby letters of credit is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments.

Financial instruments with off-balance sheet risk at December 31 are as follows:

Contract or Notional Amount                           1997                1996
------------------------------------------------------------------------------
(in thousands)
Financial instruments whose contract amount
  represents credit risk:
   Commitments to originate 1-4 family mortgages   $   163             $   106
   Standby letters of credit                         1,561                 945
   Unused lines of credit                           85,204              66,696
   Unadvanced portions of construction loans           321               2,190
Financial instruments whose contract amount
  exceeds the amount of credit risk:
   Commitments to sell 1-4 family mortgages            388                 663

Commitments to originate loans, unadvanced portions of construction loans and unused lines of credit are generally agreements to lend to a customer provided there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer's credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management's credit evaluation of the borrower.

Standby letters of credit are conditional commitments issued by the Company to guarantee the performance by a customer to a third party. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers.

In addition to general commitments, the Company originates 1-4 family mortgages for sale in the secondary markets. These loans are sold with and without recourse and no loan is originated without its sale having been pre-arranged. The Company was servicing mortgage loans sold to others with a maximum recourse provision of 10% of the outstanding balance of approximately $753,000 at December 31, 1997 and $1,092,000 at December 31, 1996.

18. FAIR VALUES OF FINANCIAL INSTRUMENTS

The following methods and assumptions were used by the Company in estimating fair values of its financial instruments. Excluded from this disclosure are certain financial instruments for which it is not practical to estimate their value and all nonfinancial instruments. Accordingly, the aggregate fair value amounts presented do not represent the underlying value of the Company.

Cash and cash equivalents: The carrying amounts reported in the balance sheet for cash and cash equivalents approximate the fair values of these assets because of the short-term nature of these financial instruments.

Securities held-to-maturity and securities available-for-sale: The fair value of these securities, excluding certain state and municipal securities whose fair value is estimated at book value because they are not readily marketable, is estimated based on bid prices published in financial newspapers or bid quotations received from securities dealers.

Loans: For variable-rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying amounts. The fair value of other loans is estimated using discounted cash flow analysis, based on interest rates currently being offered for loans with similar terms to borrowers of similar credit quality. Incremental credit risk for non-performing loans has been considered.

Accrued interest receivable and payable: The carrying amounts for accrued interest receivable and payable approximate fair values because of the short-term nature of these financial instruments.

Deposits: The fair value of deposits with no stated maturity, such as noninterest bearing demand deposits, savings, N.O.W. and money market accounts, is equal to the amount payable on demand as of the balance sheet date. The fair value of certificates of deposit is based on the discounted value of contractual cash flows. The discount rate used is estimated based on the rates currently offered for deposits of similar remaining maturities.

Repurchase agreements and other borrowed funds: The carrying amounts reported in the balance sheet for repurchase agreements and other borrowed funds approximate the fair values of those liabilities because of the short-term nature of these financial instruments.

Off-balance-sheet instruments: The fair values of the Company's unused lines of credit, commitments to originate and sell loans and standby letters of credit are estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties' credit standing. The fair value of the Company's commitments to sell mortgage loans approximates the estimated cost to terminate or otherwise settle the obligations with the counterparties. Therefore, at December 31, 1997 and 1996, there was no fair value adjustment.

LIMITATIONS

Fair value estimates are made at a specific point in time, based on relevant market information and information about the type of financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Bank's entire holdings of a particular financial instrument. Because no market exists for some of the Bank's financial instruments, fair value estimates are based on judgements regarding future expected loss experience, cash flows, current economic conditions, risk characteristics and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgement and therefore cannot be determined with precision. Changes in assumptions and changes in the loan, debt and interest rate markets could significantly affect the estimates. Further, the income tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on the fair value estimates and have not been considered.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

21. SUBSEQUENT EVENT - ACQUISITION

In December 1997, Century Bancorp, Inc. announced an agreement to acquire Haymarket Cooperative Bank ("Haymarket") and merge Haymarket into Century Bank and Trust Company. This acquisition is expected to be completed on or before April 1, 1998. Haymarket is headquartered in Boston, Massachusetts and operates two banking offices located in Boston. Haymarket is engaged principally in the business of attracting deposits from the general public and investing those deposits in residential real estate, consumer and small business loans.

Total assets of Haymarket were approximately $142 million at December 31, 1997. Under the terms of the agreement, Century Bank and Trust Company will pay approximately $20 million in cash for Haymarket and the acquisition is subject to federal and state regulatory approval. The transaction will be accounted for using the purchase method of accounting.

The following pro-forma condensed balance sheet was prepared as if this acquisition had taken place at December 31, 1997.

THE BOARD OF DIRECTORS CENTURY BANCORP, INC.:

We have audited the accompanying consolidated balance sheets of Century Bancorp, Inc. and subsidiary (the Company) as of December 31, 1997 and 1996, and the related consolidated statements of income, changes in stockholders' equity and cash flows for each of the years in the three-year period ended December 31, 1997. These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Century Bancorp, Inc. and subsidiary as of December 31, 1997 and 1996, and the results of their operations and their cash flows for each of the years in the three-year period ended December 31, 1997 in conformity with generally accepted accounting principles.

COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

Decisions on compensation of the Company's executives are generally made by the Compensation Committee of the Board of Directors. Each member of the Compensation Committee is a non-employee director. The goal of the Committee is to provide competitive levels of compensation in order to attract and retain qualified executive personnel. The Compensation Committee believes that the actions of each executive officer have the potential to affect the short and long term profitability of the Company. Accordingly, the Compensation Committee places considerable importance on the design and administration of the executive compensation program.

The Company has an executive compensation program that is driven by the overall performance of the Company, the increase in shareholder value, the performance of the business unit directly affected by the executive and by the performance of the individual executive. The three primary components of the executive compensation program are base salary, cash incentive plan and stock based incentive plans.

-47-

BASE SALARY

Base salary levels are set so that the Company has the management talent to meet the challenges in the financial services industry. Several factors are included in setting base salaries including the responsibilities of the executive officer, the scope of the executive's position, individual performance and salary levels at peer banks. Historically, the Company's executive compensation practices have been designed to provide total compensation in the middle range of compensation levels at similar banking institutions. Salary increases for the senior management group have averaged 3% to 6% during the last several years.

CASH INCENTIVE PLANS

The Company has a cash incentive compensation plan which provides for the award of bonuses up to a percentage of base salary to officers of the Company or its subsidiaries. Recipients of incentive compensation are selected by the Compensation Committee, upon the recommendation of management, as eligible to participate in the plan. Awards are based upon the attainments of established objectives including profitability, expense control, sales volume and overall job performance. No bonuses are paid unless actual earnings are at least 85% of budgeted net income. Upon recommendation of the Compensation Committee, the Board of Directors determines the amounts, if any, to be awarded. Earned bonuses for 1997, 1996 and 1995 are shown in the Summary Compensation Table.

STOCK INCENTIVE PLANS

One of the Compensation Committee's priorities is for executives to be significant shareholders so that the interest of the executives are aligned with the shareholders and decisions are made as owners of the Company. On March 10, 1987, the stockholders approved a Stock Option Plan (the "Option Plan") that the Board of Directors adopted on February 24, 1987, that provides for grants of options to purchase no more than 150,000 shares of Class A Common Stock. Options may be granted, in the discretion of the Board of Directors, to officers and other key employees of the Company. Options granted under the Option Plan may be either incentive stock options as defined in the Internal Revenue Code or non-qualified stock options. The Option Plan is administrated by the Compensation Committee (whose members are ineligible to participate in the Option Plan) which makes recommendations, based upon management's recommendations, to the Board of Directors as to persons to whom options are to be granted, the number of shares to be optioned to each, the option price (which may not be less than 85% of the fair market value for non-qualified stock options, or the fair market value for incentive stock options, of the shares on the date of grant) and the time periods during which options are exercisable (no more than ten years from the date of grants). In the event of a reorganization, as defined in the Option Plan, the Board of Directors may terminate the exercise period by giving 30 days notice to all participants, during which time all outstanding options may be exercised. Options for 146,500 shares were granted in 1994.

EXECUTIVE BENEFITS

The Company's executive compensation package includes a special benefits component in addition to base salary and cash and stock incentive plans. These special benefits are viewed as less important than the above. Where such benefits are provided, they are intended to support other business purposes including facilitating business development efforts.

CHIEF EXECUTIVE OFFICER COMPENSATION

Mr. Marshall Sloane is eligible to participate in the same executive compensation plans available to other executive officers described above. The 1997 cash compensation for Mr. Sloane was $563,460 of which $438,200 was base salary.

CONCLUSION

The Compensation Committee believes that the executive compensation package will motivate the management team to produce the results the Company has historically achieved.

SUPPLEMENTAL EXECUTIVE INSURANCE/RETIREMENT INCOME PLAN

Executive officers of the Company or its subsidiaries who have at least one year of service may participate in the Supplemental Executive Insurance/Retirement Income Plan (the "Supplemental Plan").

The Company maintains split dollar life insurance policies for participants, in addition to the group term life insurance, which provides life insurance equal to twice the individual's salary with a maximum of $200,000, which they receive under a policy the Company maintains for its employees generally. The split dollar insurance provides death benefits if the participant dies while in the employ of the Company, equal to $2,191,000, $955,500, $635,000, $770,000, $739,000 for Messrs. Marshall M. Sloane, Swansburg, Lang, Jonathan G. Sloane and Sloboda.

Premiums paid by the Company in 1997 amounted to $87,800, $31,700, $27,600, $8,300, $28,400, for policies on the lives of Messrs. Marshall M. Sloane, Swansburg, Lang, Jonathan G. Sloane and Sloboda. The policies are on an "insurance bonus" basis, which means that the Company pays the full amount of all premiums on the policies but an amount equal to the one-year term cost of the insurance is treated for tax purposes as a bonus to the insured. The Company is the owner of these policies and each participating employee has received an assignment of a portion of each policy's proceeds. Upon the death of a participant, the Company will receive benefits equal to the difference between the death benefits payable to the named beneficiary under the Supplemental Plan and the face amount of the policy (less any policy loans then in force).

A participant in the Supplemental Plan is also entitled to retirement benefits. Participants, upon retirement at age 65, after a specified number of years of service, are entitled to receive for life, with ten years certain, 75% of their highest 60 months salary for certain executives, or 66% of such salary if the participants are Senior Vice Presidents and equivalents (as determined by the Compensation Committee), less the primary social security benefits and the benefit received from the defined benefit retirement plan. If a participant retires or terminates employment prior to age 65 such person is entitled to a reduced benefit. Five years of service are required for any benefits to become vested. Thereafter benefits vest incrementally.

The following table illustrates representative annual retirement benefits at various compensation levels for executive management employees under the Supplemental Plan who retire at age 65 and with 15 years of service, without reflecting the required offset of benefits from social security and the defined benefit retirement plan.

     Five Year

        300,000                                 225,000

As of January 1, 1997, Messrs. Marshall M. Sloane, Swansburg, Lang, Jonathan G. Sloane, and Sloboda were 100%, 77.5%, 85.0%, 100%, and 100% vested, respectively, under the Supplemental Plan.

COMPLIANCE WITH SECTION 16(a) OF THE EXCHANGE ACT

Section 16(a) of the Exchange Act requires the Company's Executive Officers and Directors, and any persons who own more than 10% of a registered class of the Company's equity securities, to file reports of ownership and changes in ownership of securities with the SEC and NASDAQ. Executive Officers, Directors, and greater than 10% stockholders (of which, to the Company's knowledge, there currently are none) are required by SEC regulation to furnish the Company's with copies of all Section 16(a) forms they file. Based solely on a review of the copies of such reports received by it or written representations from certain reporting persons that no other reports were required, the corporation believes that, during 1997, all Section 16(a) filing requirements applicable to its Executive Officers and Directors were complied with, except that reports on initial holdings and subsequent purchases by one director were filed late.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

Indemnification. The Company is a Massachusetts corporation. Massachusetts General Laws Chapter 156B, Section 67 provides that a corporation may, subject to certain limitations, indemnify its directors, officers, employees and other agents, and persons who serve at its request as directors, officers, employees or other agents of another organization, or who serve at its request in any capacity with respect to any employee benefit plan, to the extent specified or authorized by the corporation's articles of organization, a by-law adopted by the stockholders, or a vote adopted by the holders of a majority of the shares of stock entitled to vote on the election of directors.

Section 67 also provides that a corporation may purchase and maintain insurance against liability incurred by an officer or director in his capacity as officer or director, or arising out of his status as such, whether or not the corporation would have the power to indemnify him against such liability.

The Company's Articles of Organization provide that directors and officers of the Company and each person who, at the request of or by reason of an election effected in whole or in major part by the Company shall, be indemnified by the Company against liabilities and expenses arising out of service for or on behalf of the Company. The Articles provide that the indemnification provision in the Articles does not limit any other right to indemnification existing independently of the Articles including the discretionary power of the Board of Directors in granting or refusing indemnification to such other personnel.

Under the Articles, indemnification may include payment by the Company of expenses incurred in defending a civil or criminal action or proceeding in advance of the final disposition of such action or proceeding, upon receipt of an undertaking by the person indemnified to repay such payment unless the payment of the indemnification with respect to such expenses is authorized by the Board of Directors in accordance with the Articles. Any such indemnification may be provided even if the person to be indemnified is no longer an officer or director of the Company.

60

The Articles provide that the Company is authorized to enter into agreements with its directors and officers providing indemnification procedures different from those set forth in the Articles, and to purchase and maintain liability insurance for itself and any director, officer, employee or agent of the Company.

Limitation of Liability. Massachusetts General Laws Chapter 156B,
Section 13 enables a corporation in its original articles of organization or an amendment thereto to eliminate or limit the personal liability of a director for monetary damages for violations of the director's fiduciary duty, except (i) for any breach of the director's duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) pursuant to Sections 61 and 62 of Chapter 156B (providing for liability of directors for authorizing illegal distributions and for making loans to directors, officers and certain shareholders) or (iv) for any transaction from which a director derived an improper personal benefit. The Company's Articles and By-laws currently contain no limitation of liability provisions.

ITEM 17. UNDERTAKINGS.

The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, as amended (the "Act"), each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in this 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.

Insofar as indemnification for liabilities arising under the Act may be permitted to directors, officers and controlling persons of each undersigned Registrant pursuant to the foregoing provisions, or otherwise, each 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 each undersigned Registrant of expenses incurred or paid by a director, officer of controlling person of each 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, each Registrant will, unless in the opinion of its counsel the matter has been settled by the controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

The undersigned Registrant hereby undertakes that: (1) For purposes of determining any liability under the Act, the information omitted from the form of prospectus filed as part of this Registration Statement in reliance upon Rule 430A and contained in a form of prospectus filed by the Company pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this Registration Statement as of the time it was declared effective; and (2) for the purpose of determining any liability under the Act, each post-effective amendment that contains a form of prospectus 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.

(b) The amount of interest payable for any period shall be computed on the basis of a 360-day year of twelve 30-day months. The amount of interest payable for any period shorter than a full quarterly period for which interest is computed shall be computed on the basis of the number of days elapsed in a 360-day year of twelve 30-day months. In the event that any date on which interest is payable on the Debentures is not a Business Day, then payment of interest payable on such date shall be made on the next succeeding day which is a Business Day (and without any interest or other payment in respect of any such delay) with the same force and effect as if made on the date such payment was originally payable.

(c) If, at any time while the Property Trustee is the holder of any Debentures, the Trust or the Property Trustee is required to pay any taxes, duties, assessments or governmental charges of whatever nature (other than withholding taxes) imposed by the United States, or any other taxing authority, then, in any case, the Company shall pay as additional interest ("Additional Interest") on the Debentures held by the Property Trustee, such additional amounts as shall be required so that the net amounts received and retained by the Trust and the Property Trustee after paying such taxes, duties, assessments or other governmental charges shall be equal to the amounts the Trust and the Property Trustee would have received had no such taxes, duties, assessments or other government charges been imposed.

SECTION 2.6. EXECUTION AND AUTHENTICATIONS.

(a) The Debentures shall be signed on behalf of the Company by its Chief Executive Officer, President or one of its Vice Presidents, under its corporate seal attested by its Secretary or one of its Assistant Secretaries. Signatures may be in the form of a manual or facsimile signature. The Company may use the facsimile signature of any Person who shall have been a Chief Executive Officer, President or Vice President thereof, or of any Person who shall have been a Secretary or Assistant Secretary thereof, notwithstanding the fact that at the time the Debentures shall be authenticated and delivered or disposed of such Person shall have ceased to be the Chief Executive Officer, President or a Vice President, or the Secretary or an Assistant

-11-

Secretary, of the Company. The seal of the Company may be in the form of a facsimile of such seal and may be impressed, affixed, imprinted or otherwise reproduced on the Debentures. The Debentures may contain such notations, legends or endorsements required by law, stock exchange rule or usage. Each Debenture shall be dated the date of its authentication by the Trustee.

(b) A Debenture shall not be valid until manually authenticated by an authorized signatory of the Trustee, or by an Authenticating Agent. Such signature shall be conclusive evidence that the Debenture so authenticated has been duly authenticated and delivered hereunder and that the holder is entitled to the benefits of this Indenture.

(c) At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Debentures executed by the Company to the Trustee for authentication, together with a written order of the Company for the authentication and delivery of such Debentures signed by its Chief Executive Officer, President or any Vice President and its Treasurer or any Assistant Treasurer, and the Trustee in accordance with such written order shall authenticate and deliver such Debentures.

(d) In authenticating such Debentures and accepting the additional responsibilities under this Indenture in relation to such Debentures, the Trustee shall be entitled to receive, and (subject to Section 9.1) shall be fully protected in relying upon, an Opinion of Counsel stating that the form and terms thereof have been established in conformity with the provisions of this Indenture.

(e) The Trustee shall not be required to authenticate such Debentures if the issue of such Debentures pursuant to this Indenture shall affect the Trustee's own rights, duties or immunities under the Debentures and this Indenture or otherwise in a manner that is not reasonably acceptable to the Trustee.

SECTION 2.7. REGISTRATION OF TRANSFER AND EXCHANGE.

(a) Debentures may be exchanged upon presentation thereof at the office or agency of the Company designated for such purpose in Boston, Massachusetts , or at the office of the Debenture Registrar, for other Debentures and for a like aggregate principal amount, upon payment of a sum sufficient to cover any tax or other governmental charge in relation thereto, all as provided in this Section
2.7. In respect of any Debentures so surrendered for exchange, the Company shall execute, the Trustee shall authenticate and such office or agency shall deliver in exchange therefor the Debenture or Debentures that the Debentureholder making the exchange shall be entitled to receive, bearing numbers not contemporaneously outstanding.

(b) The Company shall keep, or cause to be kept, at its office or agency designated for such purpose in Boston, Massachusetts, or at the office of the Debenture Registrar, or such other location designated by the Company a register or registers (herein referred to as the "Debenture Register") in which, subject to such reasonable regulations as it may prescribe, the Company shall register the Debentures and the transfers of Debentures as in this Article II provided and which at all reasonable times shall be open for inspection by the Trustee. The registrar for the

-12-

purpose of registering Debentures and transfer of Debentures as herein provided shall initially be the Trustee and thereafter as may be appointed by the Company as authorized by Board Resolution (the "Debenture Registrar"). Upon surrender for transfer of any Debenture at the office or agency of the Company designated for such purpose, the Company shall execute, the Trustee shall authenticate and such office or agency shall deliver in the name of the transferee or transferees a new Debenture or Debentures for a like aggregate principal amount. All Debentures presented or surrendered for exchange or registration of transfer, as provided in this Section 2.7, shall be accompanied (if so required by the Company or the Debenture Registrar) by a written instrument or instruments of transfer, in form satisfactory to the Company or the Debenture Registrar, duly executed by the registered holder or by such holder's duly authorized attorney in writing.

(c) No service charge shall be made for any exchange or registration of transfer of Debentures, or issue of new Debentures in case of partial redemption, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge in relation thereto, other than exchanges pursuant to Section 2.8, Section 3.5(b) and Section 11.4 not involving any transfer.

(d) The Company shall not be required (i) to issue, exchange or register the transfer of any Debentures during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of less than all the Outstanding Debentures and ending at the close of business on the day of such mailing; nor (ii) to register the transfer of or exchange any Debentures or portions thereof called for redemption.

SECTION 2.8. TEMPORARY DEBENTURES.

Pending the preparation of definitive Debentures, the Company may execute, and the Trustee shall authenticate and deliver, temporary Debentures (printed, lithographed, or typewritten). Such temporary Debentures shall be substantially in the form of the definitive Debentures in lieu of which they are issued, but with such omissions, insertions and variations as may be appropriate for temporary Debentures, all as may be determined by the Company. Every temporary Debenture shall be executed by the Company and be authenticated by the Trustee upon the same conditions and in substantially the same manner, and with like effect, as the definitive Debentures. Without unnecessary delay the Company shall execute and shall furnish definitive Debentures and thereupon any or all temporary Debentures may be surrendered in exchange therefor (without charge to the holders), at the office or agency of the Company designated for the purpose in Boston, Massachusetts, and the Trustee shall authenticate and such office or agency shall deliver in exchange for such temporary Debentures an equal aggregate principal amount of definitive Debentures, unless the Company advises the Trustee to the effect that definitive Debentures need not be executed and furnished until further notice from the Company. Until so exchanged, the temporary Debentures shall be entitled to the same benefits under this Indenture as definitive Debentures authenticated and delivered hereunder.

-13-

SECTION 2.9. MUTILATED, DESTROYED, LOST OR STOLEN DEBENTURES.

(a) In case any temporary or definitive Debenture shall become mutilated or be destroyed, lost or stolen, the Company (subject to the next succeeding sentence) shall execute, and upon the Company's request the Trustee (subject as aforesaid) shall authenticate and deliver, a new Debenture bearing a number not contemporaneously outstanding, in exchange and substitution for the mutilated Debenture, or in lieu of and in substitution for the Debenture so destroyed, lost or stolen. In every case the applicant for a substituted Debenture shall furnish to the Company and the Trustee such security or indemnity as may be required by them to save each of them harmless, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company and the Trustee evidence to their satisfaction of the destruction, loss or theft of the applicant's Debenture and of the ownership thereof. The Trustee shall authenticate any such substituted Debenture and deliver the same upon the written request or authorization of the Chairman, President or any Vice President and the Treasurer or any Assistant Treasurer of the Company. Upon the issuance of any substituted Debenture, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. In case any Debenture that has matured or is about to mature shall become mutilated or be destroyed, lost or stolen, the Company may, instead of issuing a substitute Debenture, pay or authorize the payment of the same (without surrender thereof except in the case of a mutilated Debenture) if the applicant for such payment shall furnish to the Company and the Trustee such security or indemnity as they may require to save them harmless, and, in case of destruction, loss or theft, evidence to the satisfaction of the Company and the Trustee of the destruction, loss or theft of such Debenture and of the ownership thereof.

(b) Every replacement Debenture issued pursuant to the provisions of this Section 2.9 shall constitute an additional contractual obligation of the Company whether or not the mutilated, destroyed, lost or stolen Debenture shall be found at any time, or be enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Debentures duly issued hereunder. All Debentures shall be held and owned upon the express condition that the foregoing provisions are exclusive with respect to the replacement or payment of mutilated, destroyed, lost or stolen Debentures, and shall preclude (to the extent lawful) any and all other rights or remedies, notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment of negotiable instruments or other securities without their surrender.

SECTION 2.10. CANCELLATION.

All Debentures surrendered for the purpose of payment, redemption, exchange or registration of transfer shall, if surrendered to the Company or any Paying Agent, be delivered to the Trustee for cancellation, or, if surrendered to the Trustee, shall be canceled by it, and no Debentures shall be issued in lieu thereof except as expressly required or permitted by any of the provisions of this Indenture. On request of the Company at the time of such surrender, the Trustee shall deliver to the Company canceled Debentures held by the Trustee. In the absence of such request the Trustee may dispose of canceled Debentures in accordance with its standard

-14-

procedures and deliver a certificate of disposition to the Company. If the Company shall otherwise acquire any of the Debentures, however, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such Debentures unless and until the same are delivered to the Trustee for cancellation.

SECTION 2.11. BENEFIT OF INDENTURE.

Nothing in this Indenture or in the Debentures, express or implied, shall give or be construed to give to any Person, other than the parties hereto and the holders of the Debentures (and, with respect to the provisions of Article XVI, the holders of Senior Indebtedness) any legal or equitable right, remedy or claim under or in respect of this Indenture, or under any covenant, condition or provision herein contained; all such covenants, conditions and provisions being for the sole benefit of the parties hereto and of the holders of the Debentures (and, with respect to the provisions of Article XVI, the holders of Senior Indebtedness).

SECTION 2.12. AUTHENTICATION AGENT.

(a) So long as any of the Debentures remain Outstanding there may be an Authenticating Agent for any or all such Debentures, which the Trustee shall have the right to appoint. Said Authenticating Agent shall be authorized to act on behalf of the Trustee to authenticate Debentures issued upon exchange, transfer or partial redemption thereof, and Debentures so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. All references in this Indenture to the authentication of Debentures by the Trustee shall be deemed to include authentication by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Company and shall be a corporation that has a combined capital and surplus, as most recently reported or determined by it, sufficient under the laws of any jurisdiction under which it is organized or in which it is doing business to conduct a trust business, and that is otherwise authorized under such laws to conduct such business and is subject to supervision or examination by federal or state authorities. If at any time any Authenticating Agent shall cease to be eligible in accordance with these provisions, it shall resign immediately.

(b) Any Authenticating Agent may at any time resign by giving written notice of resignation to the Trustee and to the Company. The Trustee may at any time (and upon request by the Company shall) terminate the agency of any Authenticating Agent by giving written notice of termination to such Authenticating Agent and to the Company. Upon resignation, termination or cessation of eligibility of any Authenticating Agent, the Trustee may appoint an eligible successor Authenticating Agent acceptable to the Company. Any successor Authenticating Agent, upon acceptance of its appointment hereunder, shall become vested with all the rights, powers and duties of its predecessor hereunder as if originally named as an Authenticating Agent pursuant hereto.

SECTION 3.2. SPECIAL EVENT REDEMPTION.

Subject to the Company having received the prior approval of the Federal Reserve, if then required under the applicable capital guidelines or policies of the Federal Reserve, if a Special Event has occurred and is continuing, then, notwithstanding Section 3.3(a) but subject to Section 3.3(b), the Company shall have the right upon not less than 30 days nor more than 60 days notice to the holders of the Debentures to redeem the Debentures, in whole but not in part, for cash within 180 days following the occurrence of such Special Event (the "180-Day Period") at a redemption price equal to 100% of the principal amount to be redeemed plus any accrued and unpaid interest thereon to the date of such redemption (the "Redemption Price"), provided that if at the time there is available to the Company the opportunity to eliminate, within the 180-Day Period, a Tax Event by taking some ministerial action (a "Ministerial Action"), such as filing a form or making an election, or pursuing some other similar reasonable measure which has no adverse effect on the Company, the Trust or the holders of the Trust Securities issued by the Trust, the Company shall pursue such Ministerial Action in lieu of redemption, and, provided further, that the Company shall have no right to redeem the Debentures while the Trust is pursuing any Ministerial Action pursuant to its obligations hereunder. The Redemption Price shall be paid prior to 12:00 noon, Boston time, on the date of such redemption or such earlier time as the Company determines, provided that the Company shall deposit with the Trustee an amount sufficient to pay the Redemption Price by 10:00 a.m., Boston time, on the date such Redemption Price is to be paid.

SECTION 3.3. OPTIONAL REDEMPTION BY COMPANY.

(a) Subject to the provisions of Section 3.3(b), except as otherwise may be specified in this Indenture, the Company shall have the right to redeem the Debentures, in whole or in part, from time to time, on or after June 30, 2003, at a Redemption Price equal to 100% of the principal amount to be redeemed plus any accrued and unpaid interest thereon to the date of such redemption, plus Deferred Interest, if any. Any redemption pursuant to this Section 3.3(a) shall be made upon not less than 30 days nor more than 60 days notice to the holder of the Debentures, at the Redemption Price. If the Debentures are only partially redeemed pursuant to this Section 3.3, the Debentures shall be redeemed pro rata or by lot or in such other manner as the Trustee shall deem appropriate and fair in its discretion. The Redemption Price shall be paid prior to 12:00 noon, Boston time, on the date of such redemption or at such earlier time as the Company determines provided that the Company shall deposit with the Trustee an amount sufficient to pay

-16-

the Redemption Price by 10:00 a.m., Boston time, on the date such Redemption Price is to be paid.

(b) If a partial redemption of the Debentures would result in the delisting of the Preferred Securities issued by the Trust from The Nasdaq Stock Market's National Market or any national securities exchange or other organization on which the Preferred Securities are then listed, the Company shall not be permitted to effect such partial redemption and may only redeem the Debentures in whole.

SECTION 3.4. NOTICE OF REDEMPTION.

(a) In case the Company shall desire to exercise such right to redeem all or, as the case may be, a portion of the Debentures in accordance with the right reserved so to do, the Company shall, or shall cause the Trustee to upon receipt of 45 days' written notice from the Company (which notice shall, in the event of a partial redemption, include a representation to the effect that such partial redemption shall not result in the delisting of the Preferred Securities as described in Section 3.3(b) above), give notice of such redemption to holders of the Debentures to be redeemed by mailing, first class postage prepaid, a notice of such redemption not less than 30 days and not more than 60 days before the date fixed for redemption to such holders at their last addresses as they shall appear upon the Debenture Register unless a shorter period is specified in the Debentures to be redeemed. Any notice that is mailed in the manner herein provided shall be conclusively presumed to have been duly given, whether or not the registered holder receives the notice. In any case, failure duly to give such notice to the holder of any Debenture designated for redemption in whole or in part, or any defect in the notice, shall not affect the validity of the proceedings for the redemption of any other Debentures. In the case of any redemption of Debentures prior to the expiration of any restriction on such redemption provided in the terms of such Debentures or elsewhere in this Indenture, the Company shall furnish the Trustee with an Officers' Certificate evidencing compliance with any such restriction. Each such notice of redemption shall specify the date fixed for redemption and the Redemption Price and shall state that payment of the Redemption Price shall be made at the office or agency of the Company in Boston, Massachusetts or at the Corporate Trust Office, upon presentation and surrender of such Debentures, that interest accrued to the date fixed for redemption shall be paid as specified in said notice and that from and after said date interest shall cease to accrue. If less than all the Debentures are to be redeemed, the notice to the holders of the Debentures shall specify the particular Debentures to be redeemed. If the Debentures are to be redeemed in part only, the notice shall state the portion of the principal amount thereof to be redeemed and shall state that on and after the redemption date, upon surrender of such Debenture, a new Debenture or Debentures in principal amount equal to the unredeemed portion thereof shall be issued.

(b) If less than all the Debentures are to be redeemed, the Company shall give the Trustee at least 45 days' notice in advance of the date fixed for redemption as to the aggregate principal amount of Debentures to be redeemed, and thereupon the Trustee shall select, by lot or in such other manner as it shall deem appropriate and fair in its discretion, the portion or portions (equal to $10 or any integral multiple thereof) of the Debentures to be redeemed and shall thereafter promptly notify the Company in writing of the numbers of the Debentures to be

-17-

redeemed, in whole or in part. The Company may, if and whenever it shall so elect pursuant to the terms hereof, by delivery of instructions signed on its behalf by its President or any Vice President, instruct the Trustee or any Paying Agent to call all or any part of the Debentures for redemption and to give notice of redemption in the manner set forth in this Section 3.4, such notice to be in the name of the Company or its own name as the Trustee or such Paying Agent may deem advisable. In any case in which notice of redemption is to be given by the Trustee or any such Paying Agent, the Company shall deliver or cause to be delivered to, or permit to remain with, the Trustee or such Paying Agent, as the case may be, such Debenture Register, transfer books or other records, or suitable copies or extracts therefrom, sufficient to enable the Trustee or such Paying Agent to give any notice by mail that may be required under the provisions of this Section 3.4.

SECTION 3.5. PAYMENT UPON REDEMPTION.

(a) If the giving of notice of redemption shall have been completed as above provided, the Debentures or portions of Debentures to be redeemed specified in such notice shall become due and payable on the date and at the place stated in such notice at the applicable Redemption Price, and interest on such Debentures or portions of Debentures shall cease to accrue on and after the date fixed for redemption, unless the Company shall default in the payment of such Redemption Price with respect to any such Debenture or portion thereof. On presentation and surrender of such Debentures on or after the date fixed for redemption at the place of payment specified in the notice, said Debentures shall be paid and redeemed at the Redemption Price (but if the date fixed for redemption is an Interest Payment Date, the interest installment payable on such date shall be payable to the registered holder at the close of business on the applicable record date pursuant to Section 3.3).

(b) Upon presentation of any Debenture that is to be redeemed in part only, the Company shall execute and the Trustee shall authenticate and the office or agency where the Debenture is presented shall deliver to the holder thereof, at the expense of the Company, a new Debenture of authorized denomination in principal amount equal to the unredeemed portion of the Debenture so presented.

SECTION 3.6. NO SINKING FUND.

The Debentures are not entitled to the benefit of any sinking fund.

ARTICLE IV.
EXTENSION OF INTEREST PAYMENT PERIOD

SECTION 4.1. EXTENSION OF INTEREST PAYMENT PERIOD.

So long as no Event of Default has occurred and is continuing, the Company shall have the right, at any time and from time to time during the term of the Debentures, to defer payments of interest by extending the interest payment period of such Debentures for a period not exceeding 20 consecutive quarters (the "Extension Period"), during which Extension Period no

-18-

interest shall be due and payable; provided that no Extension Period may extend beyond the Maturity Date. Interest, the payment of which has been deferred because of the extension of the interest payment period pursuant to this Section 4.1, shall bear interest thereon at the Coupon Rate compounded quarterly for each quarter of the Extension Period ("Compounded Interest"). At the end of the Extension Period, the Company shall calculate (and deliver such calculation to the Trustee) and pay all interest accrued and unpaid on the Debentures, including any Additional Interest and Compounded Interest (together, "Deferred Interest") that shall be payable to the holders of the Debentures in whose names the Debentures are registered in the Debenture Register on the first record date after the end of the Extension Period. Before the termination of any Extension Period, the Company may further extend such period, provided that such period together with all such further extensions thereof shall not exceed 20 consecutive quarters, or extend beyond the Maturity Date of the Debentures. Upon the termination of any Extension Period and upon the payment of all Deferred Interest then due, the Company may commence a new Extension Period, subject to the foregoing requirements. No interest shall be due and payable during an Extension Period, except at the end thereof, but the Company may prepay at any time all or any portion of the interest accrued during an Extension Period.

SECTION 4.2. NOTICE OF EXTENSION.

(a) If the Property Trustee is the only registered holder of the Debentures at the time the Company selects an Extension Period, the Company shall give written notice to the Administrative Trustees, the Property Trustee and the Trustee of its selection of such Extension Period two Business Days before the earlier of (i) the next succeeding date on which Distributions on the Trust Securities issued by the Trust are payable; or (ii) the date the Trust is required to give notice of the record date, or the date such Distributions are payable, to The Nasdaq Stock Market's National Market or other applicable self-regulatory organization or to holders of the Preferred Securities issued by the Trust, but in any event at least one Business Day before such record date.

(b) If the Property Trustee is not the only holder of the Debentures at the time the Company selects an Extension Period, the Company shall give the holders of the Debentures and the Trustee written notice of its selection of such Extension Period at least two Business Days before the earlier of (i) the next succeeding Interest Payment Date; or (ii) the date the Company is required to give notice of the record or payment date of such interest payment to The Nasdaq Stock Market's National Market or other applicable self-regulatory organization or to holders of the Debentures.

(c) The quarter in which any notice is given pursuant to paragraphs (a) or (b) of this Section 4.2 shall be counted as one of the 20 quarters permitted in the maximum Extension Period permitted under Section 4.1.

SECTION 4.3. LIMITATION ON TRANSACTIONS.

If (i) the Company shall exercise its right to defer payment of interest as provided in Section 4.1; or (ii) there shall have occurred any Event of Default, then (a) the Company shall

-19-

not declare or pay any dividend on, make any distributions with respect to, or redeem, purchase, acquire or make a liquidation payment with respect to, any of its capital stock; (b) the Company shall not make any payment of interest, principal or premium, if any, or repay, repurchase or redeem any debt securities issued by the Company which rank pari passu with or junior to the Debentures; or make any guarantee payments with respect to any guarantee by the Company of the debt securities of any subsidiary of the Company if such guarantee ranks pari passu with or junior in interest to the Debentures; provided, however, that notwithstanding the foregoing the Company may make payments pursuant to its obligations under the Preferred Securities Guarantee; and (c) the Company shall not redeem, purchase or acquire less than all of the Outstanding Debentures or any of the Preferred Securities.

ARTICLE V.
PARTICULAR COVENANTS OF THE COMPANY

SECTION 5.1. PAYMENT OF PRINCIPAL AND INTEREST.

The Company shall duly and punctually pay or cause to be paid the principal of and interest on the Debentures at the time and place and in the manner provided herein.

SECTION 5.3. PAYING AGENTS.

(a) The Property Trustee shall act as the Paying Agent.

(b) If the Company shall act as its own Paying Agent with respect to the Debentures, it shall on or before each due date of the principal of or interest on such Debentures, set aside, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay such principal or interest so becoming due on Debentures until such sums shall be paid to such Persons or otherwise disposed of as herein provided and shall promptly notify the Trustee of such action, or any failure (by it or any other obligor on such Debentures) to take such action. Whenever the Company shall have one or more Paying Agents for the Debentures, it shall, prior to each due date of the principal of or interest on any Debentures, deposit with the Paying Agent a sum sufficient to pay the principal or interest so becoming due, such sum to be held in trust for the benefit of the Persons entitled to such principal or interest, and (unless such Paying Agent is the Trustee) the Company shall promptly notify the Trustee of this action or failure so to act.

-21-

Agent shall be released from all further liability with respect to such money.

SECTION 5.4. APPOINTMENT TO FILL VACANCY IN OFFICE OF TRUSTEE.

The Company, whenever necessary to avoid or fill a vacancy in the office of Trustee, shall appoint, in the manner provided in Section 9.11, a Trustee, so that there shall at all times be a Trustee hereunder.

SECTION 5.5. COMPLIANCE WITH CONSOLIDATION PROVISIONS.

The Company shall not, while any of the Debentures remain Outstanding, consolidate with, or merge into, or merge into itself, or sell or convey all or substantially all of its property to any other company unless the provisions of Article XII hereof are complied with.

(iii) the Company fails to observe or perform any other of its covenants or agreements with respect to the Debentures for a period of 90 days after the date on which written notice of such failure, requiring the same to be remedied and stating that such notice is a "Notice of Default" hereunder, shall have been given to the Company by the Trustee, by registered or certified mail, or to the Company and the Trustee by the holders of at least 25% in principal amount of the Debentures at the time Outstanding;

Subject to the provisions of Section 9.1, the Trustee shall have the right to decline to follow any such direction if the Trustee in good faith shall, by a Responsible Officer or Officers of the Trustee, determine that the proceeding so directed would involve the Trustee in personal liability. The holders of a majority in aggregate principal amount of the Debentures at the time Outstanding affected thereby, determined in accordance with Section 10.4, may on behalf of the holders of all of the Debentures waive any past default in the performance of any of the covenants contained herein and its consequences, except (i) a default in the payment of the principal of or interest on, any of the Debentures as and when the same shall become due by the terms of such Debentures otherwise than by acceleration (unless such default has been cured and a sum sufficient to pay all matured installments of principal and interest has been deposited with the Trustee (in accordance

Upon any such waiver, the default covered thereby shall be deemed to be cured for all purposes of this Indenture and the Company, the Trustee and the holders of the Debentures shall be restored to their former positions and rights hereunder, respectively; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon.

SECTION 7.7. UNDERTAKING TO PAY COSTS.

All parties to this Indenture agree, and each holder of any Debentures by such holder's acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys' fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section 7.7 shall not apply to any suit instituted by the Trustee, to any suit instituted by any Debentureholder, or group of Debentureholders holding more than 10% in aggregate principal amount of the Outstanding Debentures, or to any suit instituted by any Debentureholder for the enforcement of the payment of the principal of or interest on the Debentures, on or after the respective due dates expressed in such Debenture or established pursuant to this Indenture.

In case an Event of Default has occurred that has not been cured or waived, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs.

(b) No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that:

(i) prior to the occurrence of an Event of Default and after the curing or waiving of all such Events of Default that may have occurred:

(A) the duties and obligations of the Trustee shall with respect to the Debentures be determined solely by the express provisions of this Indenture, and the Trustee shall not be liable with respect to the Debentures except for the performance of such duties and obligations as are specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

(iv) none of the provisions contained in this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur personal financial liability in the performance of any of its duties or in the exercise of any of its rights or powers, if there is reasonable ground for believing that the repayment of such funds or liability is not reasonably assured to it under the terms of this Indenture or adequate indemnity against such risk is not reasonably assured to it.

SECTION 9.2. NOTICE OF DEFAULTS.

Within 90 days after actual knowledge by a Responsible Officer of the Trustee of the occurrence of any default hereunder with respect to the Debentures, the Trustee shall transmit by mail to all holders of the Debentures, as their names and addresses appear in the Debenture Register, notice of such default, unless such default shall have been cured or waived; provided, however, that, except in the case of a default in the payment of the principal or interest (including any Additional Interest) on any Debenture, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee or a trust committee of the directors and/or Responsible Officers of the Trustee determines in good faith that the withholding of such notice is in the interests of the holders of such Debentures; and provided, further, that in the case of any default of the character specified in section 7.1(a)(iii), no such notice to holders of Debentures need be sent until at least 30 days after the occurrence thereof.

SECTION 9.3. CERTAIN RIGHTS OF TRUSTEE.

Except as otherwise provided in Section 9.1:

(a) The Trustee may rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval, bond, security or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties;

The reasonable expense of every such examination shall be paid by the Company or, if paid by the Trustee, shall be repaid by the Company upon demand; and

(h) The Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed with due care by it hereunder.

Subject to the provisions of Section 13.5, all moneys received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received, but need not be segregated from other funds except to the extent required by law.

-34-

(b) The obligations of the Company under this Section 9.7 to compensate and indemnify the Trustee and to pay or reimburse the Trustee for expenses, disbursements and advances shall constitute additional indebtedness hereunder.

SECTION 9.8. RELIANCE ON OFFICERS' CERTIFICATE.

Except as otherwise provided in Section 9.1, whenever in the administration of the provisions of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or suffering or omitting to take any action hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of negligence or bad faith on the part of the Trustee, be deemed to be conclusively proved and established by an Officers' Certificate delivered to the Trustee and such certificate, in the absence of negligence or bad faith on the part of the Trustee, shall be full warrant to the Trustee for any action taken, suffered or omitted to be taken by it under the provisions of this Indenture upon the faith thereof.

SECTION 9.9. DISQUALIFICATION; CONFLICTING INTERESTS.

The Company may not, nor may any Person directly or indirectly controlling, controlled by, or under common control with the Company, serve as Trustee.

Such court may thereupon after such notice, if any, as it may deem proper and prescribe, appoint a successor trustee.

(b) In case at any time any one of the following shall occur:

(i) the Trustee shall fail to comply with the provisions of
Section 9.9 after written request therefor by the Company or by any Debentureholder who has been a bona fide holder of a Debenture or Debentures for at least six months; or

(ii) the Trustee shall cease to be eligible in accordance with the provisions of Section 9.10 and shall fail to resign after written request therefor by the Company or by any such Debentureholder; or

(iii) the Trustee shall become incapable of acting, or shall be adjudged a bankrupt or insolvent, or commence a voluntary bankruptcy proceeding, or a receiver of the Trustee or of its property shall be appointed or consented to, or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, then, in any such case, the Company may remove the Trustee with respect to all Debentures and appoint a successor trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor trustee, or, subject to the provisions of Section 9.10, unless the Trustee's duty to resign is stayed as provided herein, any Debentureholder who has been a bona fide holder of a Debenture or Debentures for at least six months may, on behalf of that holder and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor trustee.

(d) Any resignation or removal of the Trustee and appointment of a successor trustee with respect to the Debentures pursuant to any of the provisions of this Section 9.11 shall

-36-

become effective upon acceptance of appointment by the successor trustee as provided in Section 9.12.

(e) Any successor trustee appointed pursuant to this Section 9.11 may be appointed with respect to the Debentures, and at any time there shall be only one Trustee with respect to the Debentures.

SECTION 9.12. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

(a) In case of the appointment hereunder of a successor trustee with respect to the Debentures, every successor trustee so appointed shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company or the successor trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor trustee all the rights, powers, and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor trustee all property and money held by such retiring Trustee hereunder.

(b) Upon request of any successor trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor trustee all such rights, powers and trusts referred to in paragraph (a) of this Section 9.12.

(c) No successor trustee shall accept its appointment unless at the time of such acceptance such successor trustee shall be qualified and eligible under this Article IX.

(d) Upon acceptance of appointment by a successor trustee as provided in this Section 9.12, the Company shall transmit notice of the succession of such trustee hereunder by mail, first class postage prepaid, to the Debentureholders, as their names and addresses appear upon the Debenture Register. If the Company fails to transmit such notice within ten days after acceptance of appointment by the successor trustee, the successor trustee shall cause such notice to be transmitted at the expense of the Company.

SECTION 9.13. MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided that such corporation shall be qualified under the provisions of Section 9.9 and eligible under the provisions of Section 9.10, without the execution or filing of any paper or any further act on the part of any of the parties hereto, anything herein to the contrary notwithstanding. In case any Debentures shall have been authenticated, but not delivered, by the Trustee then in office, any

-37-

successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Debentures so authenticated with the same effect as if such successor Trustee had itself authenticated such Debentures.

ARTICLE X.
CONCERNING THE DEBENTUREHOLDERS

SECTION 10.1. EVIDENCE OF ACTION BY HOLDERS.

(a) Whenever in this Indenture it is provided that the holders of a majority or specified percentage in aggregate principal amount of the Debentures may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or the taking of any other action), the fact that at the time of taking any such action the holders of such majority or specified percentage have joined therein may be evidenced by any instrument or any number of instruments of similar tenor executed by such holders of Debentures in Person or by agent or proxy appointed in writing.

(b) If the Company shall solicit from the Debentureholders any request, demand, authorization, direction, notice, consent, waiver or other action, the Company may, at its option, as evidenced by an Officers' Certificate, fix in advance a record date for the determination of Debentureholders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other action, but the Company shall have no obligation to do so. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other action may be given before or after the record date, but only the Debentureholders of record at the close of business on the record date shall be deemed to be Debentureholders for the purposes of determining whether Debentureholders of the requisite proportion of Outstanding Debentures have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other action, and for that purpose the Outstanding Debentures shall be computed as of the record date; provided, however, that no such authorization, agreement or consent by such Debentureholders on the record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than six months after the record date.

SECTION 10.2. PROOF OF EXECUTION BY DEBENTUREHOLDERS.

Subject to the provisions of Section 9.1, proof of the execution of any instrument by a Debentureholder (such proof shall not require notarization) or his agent or proxy and proof of the holding by any Person of any of the Debentures shall be sufficient if made in the following

-38-

manner:

(a) The fact and date of the execution by any such Person of any instrument may be proved in any reasonable manner acceptable to the Trustee.

(b) The ownership of Debentures shall be proved by the Debenture Register of such Debentures or by a certificate of the Debenture Registrar thereof.

(c) The Trustee may require such additional proof of any matter referred to in this Section 10.2 as it shall deem necessary.

SECTION 10.3. WHO MAY BE DEEMED OWNERS.

Prior to the due presentment for registration of transfer of any Debenture, the Company, the Trustee, any Paying Agent, any Authenticating Agent and any Debenture Registrar may deem and treat the Person in whose name such Debenture shall be registered upon the books of the Company as the absolute owner of such Debenture (whether or not such Debenture shall be overdue and notwithstanding any notice of ownership or writing thereon made by anyone other than the Debenture Registrar) for the purpose of receiving payment of or on account of the principal of and interest on such Debenture (subject to Section 2.3) and for all other purposes; and neither the Company nor the Trustee nor any Paying Agent nor any Authenticating Agent nor any Debenture Registrar shall be affected by any notice to the contrary.

SECTION 10.4. CERTAIN DEBENTURES OWNED BY COMPANY DISREGARDED.

In determining whether the holders of the requisite aggregate principal amount of Debentures have concurred in any direction, consent or waiver under this Indenture, the Debentures that are owned by the Company or any other obligor on the Debentures or by any Person directly or indirectly controlling or controlled by or under common control with the Company or any other obligor on the Debentures shall be disregarded and deemed not to be Outstanding for the purpose of any such determination, except that (i) for the purpose of determining whether the Trustee shall be protected in relying on any such direction, consent or waiver, only Debentures that the Trustee actually knows are so owned shall be so disregarded and (ii) for purposes of this Section 10.4, the Trust shall be deemed not to be controlled by the Company. The Debentures so owned that have been pledged in good faith may be regarded as Outstanding for the purposes of this Section 10.4, if the pledgee shall establish to the satisfaction of the Trustee the pledgee's right so to act with respect to such Debentures and that the pledgee is not a Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any such other obligor. In case of a dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee.

SECTION 10.5. ACTIONS BINDING ON FUTURE DEBENTUREHOLDERS.

At any time prior to (but not after) the evidencing to the Trustee, as provided in Section 10.1, of the taking of any action by the holders of the majority or percentage in aggregate

-39-

principal amount of the Debentures specified in this Indenture in connection with such action, any holder of a Debenture that is shown by the evidence to be included in the Debentures the holders of which have consented to such action may, by filing written notice with the Trustee, and upon proof of holding as provided in Section 10.2, revoke such action so far as concerns such Debenture. Except as aforesaid any such action taken by the holder of any Debenture shall be conclusive and binding upon such holder and upon all future holders and owners of such Debenture, and of any Debenture issued in exchange therefor, on registration of transfer thereof or in place thereof, irrespective of whether or not any notation in regard thereto is made upon such Debenture. Any action taken by the holders of the majority or percentage in aggregate principal amount of the Debentures specified in this Indenture in connection with such action shall be conclusively binding upon the Company, the Trustee and the holders of all the Debentures.

SECTION 15.11. SEPARABILITY.

In case any one or more of the provisions contained in this Indenture or in the Debentures shall for any reason be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provisions of this Indenture or of the Debentures, but this Indenture and the Debentures shall be construed as if such invalid or illegal or unenforceable provision had never been contained herein or therein.

SECTION 15.12. ASSIGNMENT.

The Company shall have the right at all times to assign any of its respective rights or obligations under this Indenture to a direct or indirect wholly owned Subsidiary of the Company, provided that, in the event of any such assignment, the Company shall remain liable for all such obligations.

This Indenture may not otherwise be assigned by the parties thereto.

SECTION 15.13. ACKNOWLEDGMENT OF RIGHTS; RIGHT OF SETOFF.

(a) The Company acknowledges that, with respect to any Debentures held by the Trust or a trustee of the Trust, if the Property Trustee fails to enforce its rights under this Indenture as the holder of the Debentures held as the assets of the Trust, any holder of Preferred Securities may

-48-

institute legal proceedings directly against the Company to enforce such Property Trustee's rights under this Indenture without first instituting any legal proceedings against such Property Trustee or any other person or entity. Notwithstanding the foregoing, and notwithstanding the provisions of Section 7.4(a) hereof, if an Event of Default has occurred and is continuing and such event is attributable to the failure of the Company to pay principal or interest on the Debentures on the date such principal or interest is otherwise payable (or in the case of redemption, on the redemption date), the Company acknowledges that a holder of Preferred Securities may directly institute a proceeding for enforcement of payment to such holder of the principal of or interest on the Debentures having a principal amount equal to the aggregate liquidation amount of the Preferred Securities of such holder on or after the respective due date specified in the Debentures.

(b) Notwithstanding anything to the contrary contained in this Indenture, the Company shall have the right to setoff any payment it is otherwise required to make hereunder in respect of any Trust Securities to the extent that the Company has previously made, or is concurrently making, a payment to the holder of such Trust Securities under the Preferred Securities Guarantee or in connection with a proceeding for enforcement of payment of the principal of or interest on the Debentures directly brought by holders of any Trust Securities.

(c) For so long as any of the Preferred Securities remain outstanding, if, upon an Event of Default, the Trust holds the Debentures and the Property Trustee fails or the holders of not less than 25% in principal amount of the Outstanding Debentures fail to declare the principal of all of the Debentures to be immediately due and payable, the holders of at least 25% in liquidation amount of the Preferred Securities then Outstanding (determined as provided in the Trust Agreement) shall have the right to make such declaration by a notice in writing to the Depositor and the Property Trustee; and upon any such declaration such declaration such principal amount of and the accrued interest on all of the Debentures shall become immediately due and payable, provided that the payment of principal and interest on such Debentures shall remain subordinated to the extent provided in this Indenture.

ARTICLE XVI.
SUBORDINATION OF DEBENTURES

SECTION 16.1. AGREEMENT TO SUBORDINATE.

The Company covenants and agrees, and each holder of Debentures issued hereunder by such holder's acceptance thereof likewise covenants and agrees, that all Debentures shall be issued subject to the provisions of this Article XVI; and each holder of a Debenture, whether upon original issue or upon transfer or assignment thereof, accepts and agrees to be bound by such provisions. The payment by the Company of the principal of and interest on all Debentures issued hereunder shall, to the extent and in the manner hereinafter set forth, be subordinated and junior in right of payment to the prior payment in full of all Senior Debt, Subordinated Debt and Additional Senior Obligations of the Company (collectively, "Senior Indebtedness") to the extent provided herein, whether outstanding at the date of this Indenture or thereafter incurred. No provision of this Article XVI shall prevent the occurrence of any default or Event of Default hereunder.

-49-

SECTION 16.2. DEFAULT ON SENIOR DEBT, SUBORDINATED DEBT OR ADDITIONAL SENIOR OBLIGATIONS.

In the event and during the continuation of any default by the Company in the payment of principal, premium, interest or any other payment due on any Senior Indebtedness of the Company, or in the event that the maturity of any Senior Indebtedness of the Company has been accelerated because of a default, then, in either case, no payment shall be made by the Company with respect to the principal (including redemption payments) of or interest on the Debentures. In the event that, notwithstanding the foregoing, any payment shall be received by the Trustee when such payment is prohibited by the preceding sentence of this
Section 16.2, such payment shall be held in trust for the benefit of, and shall be paid over or delivered to, the holders of Senior Indebtedness or their respective representatives, or to the trustee or trustees under any indenture pursuant to which any of such Senior Indebtedness may have been issued, as their respective interests may appear, but only to the extent that the holders of the Senior Indebtedness (or their representative or representatives or a trustee) notify the Trustee in writing within 90 days of such payment of the amounts then due and owing on the Senior Indebtedness and only the amounts specified in such notice to the Trustee shall be paid to the holders of Senior Indebtedness.

SECTION 16.3. LIQUIDATION; DISSOLUTION; BANKRUPTCY.

(a) Upon any payment by the Company or distribution of assets of the Company of any kind or character, whether in cash, property or securities, to creditors upon any dissolution or winding-up or liquidation or reorganization of the Company, whether voluntary or involuntary or in bankruptcy, insolvency, receivership or other proceedings, all amounts due upon all Senior Indebtedness of the Company shall first be paid in full, or payment thereof provided for in money in accordance with its terms, before any payment is made by the Company on account of the principal or interest on the Debentures; and upon any such dissolution or winding-up or liquidation or reorganization, any payment by the Company, or distribution of assets of the Company of any kind or character, whether in cash, property or securities, to which the holders of the Debentures or the Trustee would be entitled to receive from the Company, except for the provisions of this Article XVI, shall be paid by the Company or by any receiver, trustee in bankruptcy, liquidating trustee, agent or other Person making such payment or distribution, or by the holders of the Debentures or by the Trustee under this Indenture if received by them or it, directly to the holders of Senior Indebtedness of the Company (pro rata to such holders on the basis of the respective amounts of Senior Indebtedness held by such holders, as calculated by the Company) or their representative or representatives, or to the trustee or trustees under any indenture pursuant to which any instruments evidencing such Senior Indebtedness may have been issued, as their respective interests may appear, to the extent necessary to pay such Senior Indebtedness in full, in money or money's worth, after giving effect to any concurrent payment or distribution to or for the holders of such Senior Indebtedness, before any payment or distribution is made to the holders of Debentures or to the Trustee.

(b) In the event that, notwithstanding the foregoing, any payment or distribution of assets of the Company of any kind or character, whether in cash, property or securities, prohibited by

-50-

the foregoing, shall be received by the Trustee before all Senior Indebtedness of the Company is paid in full, or provision is made for such payment in money in accordance with its terms, such payment or distribution shall be held in trust for the benefit of and shall be paid over or delivered to the holders of such Senior Indebtedness or their representative or representatives, or to the trustee or trustees under any indenture pursuant to which any instruments evidencing such Senior Indebtedness may have been issued, as their respective interests may appear, as calculated by the Company, for application to the payment of all Senior Indebtedness of the Company, as the case may be, remaining unpaid to the extent necessary to pay such Senior Indebtedness in full in money in accordance with its terms, after giving effect to any concurrent payment or distribution to or for the benefit of the holders of such Senior Indebtedness.

(c) For purposes of this Article XVI, the words "cash, property or securities" shall not be deemed to include shares of stock of the Company as reorganized or readjusted, or securities of the Company or any other corporation provided for by a plan of reorganization or readjustment, the payment of which is subordinated at least to the extent provided in this Article XVI with respect to the Debentures to the payment of all Senior Indebtedness of the Company, as the case may be, that may at the time be outstanding, provided that (i) such Senior Indebtedness is assumed by the new corporation, if any, resulting from any such reorganization or readjustment; and (ii) the rights of the holders of such Senior Indebtedness are not, without the consent of such holders, altered by such reorganization or readjustment. The consolidation of the Company with, or the merger of the Company into, another corporation or the liquidation or dissolution of the Company following the conveyance or transfer of its property as an entirety, or substantially as an entirety, to another corporation upon the terms and conditions provided for in Article XII shall not be deemed a dissolution, winding-up, liquidation or reorganization for the purposes of this
Section 16.3 if such other corporation shall, as a part of such consolidation, merger, conveyance or transfer, comply with the conditions stated in Article
XII. Nothing in Section 16.2 or in this Section 16.3 shall apply to claims of, or payments to, the Trustee under or pursuant to Section 9.7.

SECTION 16.4. SUBROGATION.

(a) Subject to the payment in full of all Senior Indebtedness of the Company, the rights of the holders of the Debentures shall be subrogated to the rights of the holders of such Senior Indebtedness to receive payments or distributions of cash, property or securities of the Company, as the case may be, applicable to such Senior Indebtedness until the principal of and interest on the Debentures shall be paid in full; and, for the purposes of such subrogation, no payments or distributions to the holders of such Senior Indebtedness of any cash, property or securities to which the holders of the Debentures or the Trustee would be entitled except for the provisions of this Article XVI, and no payment over pursuant to the provisions of this Article XVI to or for the benefit of the holders of such Senior Indebtedness by holders of the Debentures or the Trustee, shall, as between the Company, its creditors other than holders of Senior Indebtedness of the Company, and the holders of the Debentures, be deemed to be a payment by the Company to or on account of such Senior Indebtedness. It is understood that the provisions of this Article XVI are and are intended solely for the purposes of defining the relative rights of the holders of the Debentures, on the one hand, and the holders of such Senior Indebtedness on the other hand.

-51-

(b) Nothing contained in this Article XVI or elsewhere in this Indenture or in the Debentures is intended to or shall impair, as between the Company, its creditors (other than the holders of Senior Indebtedness of the Company), and the holders of the Debentures, the obligation of the Company, which is absolute and unconditional, to pay to the holders of the Debentures the principal of and interest on the Debentures as and when the same shall become due and payable in accordance with their terms, or is intended to or shall affect the relative rights of the holders of the Debentures and creditors of the Company, as the case may be, other than the holders of Senior Indebtedness of the Company, as the case may be, nor shall anything herein or therein prevent the Trustee or the holder of any Debenture from exercising all remedies otherwise permitted by applicable law upon default under this Indenture, subject to the rights, if any, under this Article XVI of the holders of such Senior Indebtedness in respect of cash, property or securities of the Company, as the case may be, received upon the exercise of any such remedy.

(c) Upon any payment or distribution of assets of the Company referred to in this Article XVI, the Trustee, subject to the provisions of Article IX, and the holders of the Debentures shall be entitled to conclusively rely upon any order or decree made by any court of competent jurisdiction in which such dissolution, winding-up, liquidation or reorganization proceedings are pending, or a certificate of the receiver, trustee in bankruptcy, liquidation trustee, agent or other Person making such payment or distribution, delivered to the Trustee or to the holders of the Debentures, for the purposes of ascertaining the Persons entitled to participate in such distribution, the holders of Senior Indebtedness and other indebtedness of the Company, as the case may be, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article XVI.

SECTION 16.5. TRUSTEE TO EFFECTUATE SUBORDINATION.

Each holder of Debentures by such holder's acceptance thereof authorizes and directs the Trustee on such holder's behalf to take such action as may be necessary or appropriate to effectuate the subordination provided in this Article XVI and appoints the Trustee such holder's attorney-in-fact for any and all such purposes.

SECTION 16.6. NOTICE BY THE COMPANY.

(a) The Company shall give prompt written notice to a Responsible Officer of the Trustee of any fact known to the Company that would prohibit the making of any payment of monies to or by the Trustee in respect of the Debentures pursuant to the provisions of this Article XVI. Notwithstanding the provisions of this Article XVI or any other provision of this Indenture, the Trustee shall not be charged with knowledge of the existence of any facts that would prohibit the making of any payment of monies to or by the Trustee in respect of the Debentures pursuant to the provisions of this Article XVI, unless and until a Responsible Officer of the Trustee shall have received written notice thereof from the Company or a holder or holders of Senior Indebtedness or from any trustee therefor; and before the receipt of any such written notice, the Trustee, subject to the provisions of Section 9.1, shall be entitled in all respects to assume that no such facts exist; provided, however, that if the Trustee shall not have received the

-52-

notice provided for in this Section 16.6 at least two Business Days prior to the date upon which by the terms hereof any money may become payable for any purpose (including, without limitation, the payment of the principal of or interest on any Debenture), then, anything herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such money and to apply the same to the purposes for which they were received, and shall not be affected by any notice to the contrary that may be received by it within two Business Days prior to such date.

(b) The Trustee, subject to the provisions of Section 9.1, shall be entitled to conclusively rely on the delivery to it of a written notice by a Person representing himself to be a holder of Senior Indebtedness of the Company (or a trustee on behalf of such holder) to establish that such notice has been given by a holder of such Senior Indebtedness or a trustee on behalf of any such holder or holders. In the event that the Trustee determines in good faith that further evidence is required with respect to the right of any Person as a holder of such Senior Indebtedness to participate in any payment or distribution pursuant to this Article XVI, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of such Senior Indebtedness held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and any other facts pertinent to the rights of such Person under this Article XVI, and, if such evidence is not furnished, the Trustee may defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment.

SECTION 16.7. RIGHTS OF THE TRUSTEE; HOLDERS OF SENIOR INDEBTEDNESS.

(a) The Trustee in its individual capacity shall be entitled to all the rights set forth in this Article XVI in respect of any Senior Indebtedness at any time held by it, to the same extent as any other holder of Senior Indebtedness, and nothing in this Indenture shall deprive the Trustee of any of its rights as such holder. The Trustee's right to compensation and reimbursement of expenses as set forth in Section 9.7 shall not be subject to the subordination provisions of the Article XVI.

(b) With respect to the holders of Senior Indebtedness of the Company, the Trustee undertakes to perform or to observe only such of its covenants and obligations as are specifically set forth in this Article XVI, and no implied covenants or obligations with respect to the holders of such Senior Indebtedness shall be read into this Indenture against the Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the holders of such Senior Indebtedness and, subject to the provisions of Section 9.1, the Trustee shall not be liable to any holder of such Senior Indebtedness if it shall pay over or deliver to holders of Debentures, the Company or any other Person money or assets to which any holder of such Senior Indebtedness shall be entitled by virtue of this Article XVI or otherwise.

SECTION 16.8. SUBORDINATION MAY NOT BE IMPAIRED.

(a) No right of any present or future holder of any Senior Indebtedness of the Company to enforce subordination as herein provided shall at any time in any way be prejudiced or

-53-

impaired by any act or failure to act on the part of the Company or by any act or failure to act, in good faith, by any such holder, or by any noncompliance by the Company with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof that any such holder may have or otherwise be charged with.

(b) Without in any way limiting the generality of Section 16.8(a), the holders of Senior Indebtedness of the Company may, at any time and from time to time, without the consent of or notice to the Trustee or the holders of the Debentures, without incurring responsibility to the holders of the Debentures and without impairing or releasing the subordination provided in this Article XVI or the obligations hereunder of the holders of the Debentures to the holders of such Senior Indebtedness, do any one or more of the following: (i) change the manner, place or terms of payment or extend the time of payment of, or renew or alter, such Senior Indebtedness, or otherwise amend or supplement in any manner such Senior Indebtedness or any instrument evidencing the same or any agreement under which such Senior Indebtedness is outstanding; (ii) sell, exchange, release or otherwise deal with any property pledged, mortgaged or otherwise securing such Senior Indebtedness; (iii) release any Person liable in any manner for the collection of such Senior Indebtedness; and (iv) exercise or refrain from exercising any rights against the Company and any other Person.

IN WITNESS WHEREOF, the parties hereto have caused this Indenture to be duly executed, and their respective corporate seals to be hereunto affixed and attested, all as of the day and year first above written.

____% JUNIOR SUBORDINATED DEBENTURE
DUE JUNE 30, 2029

Century Bancorp, Inc., a Massachusetts corporation (the "Company," which term includes any successor corporation under the Indenture hereinafter referred to), for value received, hereby promises to pay to State Street Bank and Trust Company, as Property Trustee for Century Bancorp Capital Trust, or registered assigns, the principal sum of ______________________________ Thousand Dollars ($__________) on June 30, 2029 (the "Stated Maturity"), and to pay interest on said principal sum from May __, 1998, or from the most recent interest payment date (each such date, an "Interest Payment Date") to which interest has been paid or duly provided for, quarterly (subject to deferral as set forth herein) in arrears on March 31, June 30, September 30 and December 31 of each year commencing June 30, 1998, at the rate of _____% per annum until the principal hereof shall have become due and payable, and on any overdue principal and (without duplication) on any overdue installment of interest at the same rate per annum compounded quarterly. The amount of interest payable on any Interest Payment Date shall be computed on the basis of a 360-day year of twelve 30- day months. The amount of interest for any partial period shall be computed on the basis of the number of days elapsed in a 360-day year of twelve 30-day months. In the event that any date on which interest is payable on this Debenture is not a business day, then payment of interest payable on such date shall be made on the next succeeding day that is a Business Day (as defined in the Indenture) (and without any interest or other payment in respect of any such delay) with the same force and effect as if made on such date. The interest installment so payable, and punctually paid or duly provided for, on any Interest Payment Date shall, as provided in the Indenture, be paid to the person in whose name this Debenture (or one or more Predecessor Debentures, as defined in said Indenture) is registered at the close of business on the regular record date for such interest installment, which shall be the close of business on the fifteenth day of the last month of the calendar quarter in which the Interest Payment Date occurs unless otherwise provided in the Indenture. Any such interest installment not punctually paid or duly provided for shall forthwith cease to be payable to the registered holders on such regular record date and may be paid to the person in whose name this Debenture (or one or more Predecessor Debentures) is registered at the close of business on a special record date to be fixed by the Trustee for the payment of such defaulted interest, notice whereof shall be given to the registered holders of the Debentures not less than 10 days prior to such special record date, or may be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Debentures may be listed, and upon such notice as may be required by such exchange, all as more fully provided in the Indenture. The principal of and the interest on this Debenture shall be payable at the office or agency of the Trustee maintained for that purpose in any coin or currency of the United States of America that at the time of payment is legal tender for payment of public and private debts; provided,


however, that payment of interest may be made at the option of the Company by check mailed to the registered holder at such address as shall appear in the Debenture Register. Notwithstanding the foregoing, so long as the holder of this Debenture is the Property Trustee, the payment of the principal of and interest on this Debenture shall be made at such place and to such account as may be designated by the Trustee.

This Debenture may be redeemed by the Company on any date not earlier than June 30, 2003, subject to the Company having received prior approval of the Federal Reserve if then required under applicable capital guidelines or policies of the Federal Reserve.

The indebtedness evidenced by this Debenture is, to the extent provided in the Indenture, subordinate and junior in right of payment to the prior payment in full of all Senior Indebtedness (as defined in the Indenture), and this Debenture is issued subject to the provisions of the Indenture with respect thereto. Each holder of this Debenture, by accepting the same, (a) agrees to and shall be bound by such provisions; (b) authorizes and directs the Trustee on his or her behalf to take such action as may be necessary or appropriate to acknowledge or effectuate the subordination so provided; and (c) appoints the Trustee his or her attorney-in-fact for any and all such purposes. Each holder hereof, by his or her acceptance hereof, hereby waives all notice of the acceptance of the subordination provisions contained herein and in the Indenture by each holder of Senior Indebtedness, whether now outstanding or hereafter incurred, and waives reliance by each such holder upon said provisions.

This Debenture shall not be entitled to any benefit under the Indenture hereinafter referred to, be valid or become obligatory for any purpose until the Certificate of Authentication hereon shall have been signed by or on behalf of the Trustee.

The provisions of this Debenture are continued on the reverse side hereof and such continued provisions shall for all purposes have the same effect as though fully set forth at this place.

IN WITNESS WHEREOF, the Company has caused this instrument to be executed.

____% SUBORDINATED DEBENTURE

(CONTINUED)

This Debenture is one of the subordinated debentures of the Company (herein sometimes referred to as the "Debentures"), all issued or to be issued under and pursuant to an Indenture dated as of May __, 1998 (the "Indenture") duly executed and delivered between the Company and State Street Bank and Trust Company, as Trustee (the "Trustee"), to which Indenture reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the holders of the Debentures. The Debentures are limited in aggregate principal amount as specified in the Indenture.

The Company shall have the right to redeem this Debenture at the option of the Company, without premium or penalty, in whole or in part at any time on or after June 30, 2003 (an "Optional Redemption"), or at any time in certain circumstances upon the occurrence of a Special Event (as defined in the Indenture), at a redemption price (the "Redemption Price") equal to 100% of the principal amount hereof plus any accrued but unpaid interest hereon, to the date of such redemption, plus Additional Interest, if any. Any redemption pursuant to this paragraph shall be made upon not less than 30 days nor more than 60 days notice, at the Redemption Price. If the Debentures are only partially redeemed by the Company pursuant to an Optional Redemption, the Debentures shall be redeemed pro rata or by lot or by any other method utilized by the Trustee as described in the Indenture.

In the event of redemption of this Debenture in part only, a new Debenture or Debentures for the unredeemed portion hereof shall be issued in the name of the holder hereof upon the cancellation hereof.

In case an Event of Default, as defined in the Indenture, shall have occurred and be continuing, the principal of all of the Debentures may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture.

The Indenture contains provisions permitting the Company and the Trustee, with the consent of the holders of not less than a majority in aggregate principal amount of the Debentures at the time outstanding, as defined in the Indenture, to execute supplemental indentures for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or of modifying in any manner the rights of the holders of the Debentures; provided, however, that no such supplemental indenture shall (i) extend the fixed maturity of the Debentures except as provided in the Indenture, or reduce the principal amount thereof, or reduce the rate or extend the time of payment of interest thereon, without the consent of the holder of each Debenture so affected; or (ii) reduce the aforesaid percentage of Debentures, the holders of which are required to consent to any such supplemental indenture, without the consent


of the holders of each Debenture then outstanding and affected thereby. The Indenture also contains provisions permitting the holders of a majority in aggregate principal amount of the Debentures at the time outstanding, on behalf of all of the holders of the Debentures, to waive any past default in the performance of any of the covenants contained in the Indenture, or established pursuant to the Indenture, and its consequences, except a default in the payment of the principal of or interest on any of the Debentures. Any such consent or waiver by the registered holder of this Debenture (unless revoked as provided in the Indenture) shall be conclusive and binding upon such holder and upon all future holders and owners of this Debenture and of any Debenture issued in exchange herefor or in place hereof (whether by registration of transfer or otherwise), irrespective of whether or not any notation of such consent or waiver is made upon this Debenture.

No reference herein to the Indenture and no provision of this Debenture or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal and interest on this Debenture at the time and place and at the rate and in the money herein prescribed.

The Company, as further described in the Indenture, shall have the right at any time during the term of the Debentures and from time to time to extend the interest payment period of such Debentures for up to 20 consecutive quarters (each, an "Extended Interest Payment Period"), at the end of which period the Company shall pay all interest then accrued and unpaid, including any Additional Interest and Compounded Interest (as defined in the Indenture and together, the "Deferred Payments") that shall be payable to the holders of the Debentures in whose names the Debentures are registered in the Debenture Register on the first record date after the end of the Extension Period. Before the termination of any such Extended Interest Payment Period, the Company may further extend such Extended Interest Payment Period, provided that such Extended Interest Payment Period together with all such further extensions thereof shall not exceed 20 consecutive quarters. At the termination of any such Extended Interest Payment Period and upon the payment of all Deferred Payments then due, the Company may commence a new Extended Interest Payment Period.

As provided in the Indenture and subject to certain limitations therein set forth, this Debenture is transferable by the registered holder hereof on the Debenture Register of the Company, upon surrender of this Debenture for registration of transfer at the office or agency of the Trustee accompanied by a written instrument or instruments of transfer in form satisfactory to the Company or the Trustee duly executed by the registered holder hereof or his attorney duly authorized in writing, and thereupon one or more new Debentures of authorized denominations and for the same aggregate principal amount shall be issued to the designated transferee or transferees. No service charge shall be made for any such transfer, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in relation thereto.

Prior to due presentment for registration of transfer of this Debenture, the Company, the Trustee, any Paying Agent and the Debenture Registrar may deem and treat the registered holder hereof as the absolute owner hereof (whether or not this Debenture shall be overdue and notwithstanding any notice of ownership or writing hereon made by anyone other than the Debenture


Registrar) for the purpose of receiving payment of or on account of the principal hereof and interest due hereon and for all other purposes, and neither the Company nor the Trustee nor any Paying Agent nor any Debenture Registrar shall be affected by any notice to the contrary.

No recourse shall be had for the payment of the principal of or the interest on this Debenture, or for any claim based hereon, or otherwise in respect hereof, or based on or in respect of the Indenture, against any incorporator, stockholder, officer or director, past, present or future, as such, of the Company or of any predecessor or successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issuance hereof, expressly waived and released.

The Debentures are issuable only in registered form without coupons in denominations of $10 and any integral multiple thereof (or such other denominations and any integral multiple thereof as may be deemed necessary by the Company for the purpose of maintaining the eligibility of the Debentures for quotation on The Nasdaq Stock Market's National Market or any successor thereto).

All terms used in this Debenture that are defined in the Indenture shall have the meanings assigned to them in the Indenture.

The Property Trustee shall have no responsibility for the accuracy of any CUSIP number contained in such notice. All notices of redemption shall state:

(i) the Redemption Date;

(ii) the Redemption Price;

(iii) the CUSIP number;

(iv) if less than all the outstanding Trust Securities are to be redeemed, the identification and the aggregate Liquidation Amount of the particular Trust Securities to be redeemed; and

(v) that, on the Redemption Date, the Redemption Price shall become due and payable upon each such Trust Security to be redeemed and that Distributions thereon shall cease to accumulate on and after said date.

(c) The Trust Securities redeemed on each Redemption Date shall be redeemed at the Redemption Price with the proceeds from the contemporaneous redemption of Debentures. Redemptions of the Trust Securities shall be made and the Redemption Price shall be payable on each Redemption Date only to the extent that the Trust has immediately available funds then on hand and available in the Payment Account for the payment of such Redemption Price.

(d) If the Property Trustee gives a notice of redemption in respect of any Preferred Securities, then, by 12:00 noon, Boston time, on the Redemption Date, subject to Section 402(c), the Property Trustee shall deposit with the Paying Agent funds sufficient to pay the applicable

-17-

Redemption Price and shall give the Paying Agent irrevocable instructions and authority to pay the Redemption Price to the Holders thereof upon surrender of their Preferred Securities Certificates. Notwithstanding the foregoing, Distributions payable on or prior to the Redemption Date for any Trust Securities called for redemption shall be payable to the Holders of such Trust Securities as they appear on the Securities Register for the Trust Securities on the relevant record dates for the related Distribution Dates. If notice of redemption shall have been given and funds deposited as required, then upon the date of such deposit, all rights of Securityholders holding Trust Securities so called for redemption shall cease, except the right of such Securityholders to receive the Redemption Price and any Distribution payable on or prior to the Redemption Date, but without interest, and such Trust Securities shall cease to be Outstanding. In the event that any date on which any Redemption Price is payable is not a Business Day, then payment of the Redemption Price payable on such date shall be made on the next succeeding day that is a Business Day (and without any interest or other payment in respect of any such delay) with the same force and effect as if made on such date. In the event that payment of the Redemption Price in respect of any Trust Securities called for redemption is improperly withheld or refused and not paid either by the Trust or by the Depositor pursuant to the Guarantee, Distributions on such Trust Securities shall continue to accumulate, at the then applicable rate, from the Redemption Date originally established by the Trust for such Trust Securities to the date such Redemption Price is actually paid, in which case the actual payment date shall be the date fixed for redemption for purposes of calculating the Redemption Price.

(e) Payment of the Redemption Price on the Trust Securities shall be made to the record holders thereof as they appear on the Securities Register for the Trust Securities on the relevant record date, which shall be the date 15 days prior to the relevant Redemption Date.

(f) Subject to Section 403(a), if less than all the Outstanding Trust Securities are to be redeemed on a Redemption Date, then the aggregate Liquidation Amount of Trust Securities to be redeemed shall be allocated on a pro rata basis (based on Liquidation Amounts) among the Common Securities and the Preferred Securities. The particular Preferred Securities to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Property Trustee from the Outstanding Preferred Securities not previously called for redemption, by such method (including, without limitation, by lot) as the Property Trustee shall deem fair and appropriate and which may provide for the selection for redemption of portions (equal to the Liquidation Amount or an integral multiple of the Liquidation Amount in excess thereof) of the Liquidation Amount of Preferred Securities of a denomination larger than the Liquidation Amount. The Property Trustee shall promptly notify the Securities Registrar in writing of the Preferred Securities selected for redemption and, in the case of any Preferred Securities selected for partial redemption, the Liquidation Amount thereof to be redeemed. For all purposes of this Trust Agreement, unless the context otherwise requires, all provisions relating to the redemption of Preferred Securities shall relate, in the case of any Preferred Securities redeemed or to be redeemed only in part, to the portion of the Liquidation Amount of Preferred Securities which has been or is to be redeemed.

SECTION 403. SUBORDINATION OF COMMON SECURITIES.

(a) Payment of Distributions (including Additional Amounts, if applicable) on, and the Redemption Price of, the Trust Securities, as applicable, shall be made, subject to Section 402(f), pro rata among the Common Securities and the Preferred Securities based on the Liquidation Amount of the Trust Securities; provided, however, that if on any Distribution Date or Redemption Date any Event of Default resulting from a Debenture Event of Default shall have occurred and be continuing, no payment of any Distribution (including Additional Amounts, if applicable) on, or Redemption Price of, any Common Security, and no other payment on account of the redemption, liquidation or other acquisition of Common Securities, shall be made unless payment in full in cash of all accumulated and unpaid Distributions (including Additional Amounts, if applicable) on all Outstanding Preferred Securities for all Distribution periods terminating on or prior thereto, or in the case of payment of the Redemption Price the full amount of such Redemption Price on all Outstanding Preferred Securities then called for redemption, shall have been made or provided for, and all funds immediately available to the Property Trustee shall first be applied to the payment in full in cash of all Distributions (including Additional Amounts, if applicable) on, or the Redemption Price of, Preferred Securities then due and payable.

(b) In the case of the occurrence of any Event of Default resulting from a Debenture Event of Default, the Holder of Common Securities shall be deemed to have waived any right to act with respect to any such Event of Default under this Trust Agreement until the effect of all such Events of Default with respect to the Preferred Securities shall have been cured, waived or otherwise eliminated. Until any such Event of Default under this Trust Agreement with respect to the Preferred Securities shall have been so cured, waived or otherwise eliminated, the Property Trustee shall act solely on behalf of the Holders of the Preferred Securities and not the Holder of the Common Securities, and only the Holders of the Preferred Securities shall have the right to direct the Property Trustee to act on their behalf.

SECTION 404. PAYMENT PROCEDURES.

Payments of Distributions (including Additional Amounts, if applicable) in respect of the Preferred Securities shall be made by check mailed to the address of the Person entitled thereto as such address shall appear on the Securities Register. Payments in respect of the Common Securities shall be made in such manner as shall be mutually agreed between the Property Trustee and the Common Securityholder.

Upon receipt under the Debentures of Additional Interest, the Property Trustee, at the direction of an Administrative Trustee or the Depositor, shall promptly pay any taxes, duties or governmental charges of whatsoever nature (other than withholding taxes) imposed on the Trust by the United States or any other taxing authority.

SECTION 407. PAYMENTS UNDER INDENTURE.

Any amount payable hereunder to any Holder of Preferred Securities shall be reduced by the amount of any corresponding payment such Holder has directly received under the Indenture pursuant to Section 514(b) or (c) hereof.

In connection with the issuance of any new Trust Securities Certificate under this Section 505, the Administrative Trustees or the Securities Registrar may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith. Any duplicate Trust Securities Certificate issued pursuant to this Section 505 shall constitute conclusive evidence of an undivided beneficial interest in the assets of the Trust, as if originally

-22-

issued, whether or not the lost, stolen or destroyed Trust Securities Certificate shall be found at any time.

SECTION 506. PERSONS DEEMED SECURITYHOLDERS.

The Trustees, the Paying Agent and the Securities Registrar shall treat the Person in whose name any Trust Securities Certificate shall be registered in the Securities Register as the owner of such Trust Securities Certificate for the purpose of receiving Distributions and for all other purposes whatsoever, and neither the Trustees nor the Securities Registrar shall be bound by any notice to the contrary.

The Administrative Trustees may revoke such power and remove the Paying Agent if such Trustees determine in their sole discretion that the Paying Agent shall have failed to perform its obligations under this Trust Agreement in any material respect. Any Person acting as Paying Agent shall be permitted to resign as Paying Agent upon 30 days' written notice to the Administrative Trustees, the Property Trustee and the Depositor. In the event that the Property Trustee shall no longer be the Paying Agent or a successor Paying Agent shall resign or its authority to act be revoked, the Administrative Trustees shall appoint a successor that is acceptable to the Property Trustee and the Depositor to act as Paying Agent (which shall be a bank or trust company). The Administrative Trustees shall cause such successor Paying Agent or any additional Paying Agent appointed by the Administrative Trustees to execute and deliver to the Trustees an instrument in which such successor Paying Agent or additional Paying Agent shall agree with the Trustees that as Paying Agent, such successor Paying Agent or additional Paying Agent shall hold all sums, if any, held by it for payment to the Securityholders in trust for the benefit of the Securityholders entitled thereto until such sums shall be paid to such Securityholders. The Paying Agent shall return all unclaimed funds to the Property Trustee and, upon removal of a Paying Agent, such Paying Agent shall also return all funds in its possession to the Property Trustee. The provisions of Sections 801, 803 and 806 shall apply to the Property Trustee also in its role as Paying Agent, for so long as the Property Trustee shall act as Paying Agent and, to the extent applicable, to any other Paying Agent appointed hereunder. Any reference in this Trust Agreement to the Paying Agent shall include any co-paying agent unless the context requires otherwise.

SECTION 510. OWNERSHIP OF COMMON SECURITIES BY DEPOSITOR.

On the Closing Date, the Depositor shall acquire and retain beneficial and record ownership of the Common Securities.

The Administrative Trustees shall cause each Common Securities Certificate issued to the Depositor to contain a legend stating "THIS CERTIFICATE IS NOT
TRANSFERABLE".

SECTION 513. [Intentionally Omitted]

SECTION 514. RIGHTS OF SECURITYHOLDERS.

The Trust Securities shall be personal property giving only the rights specifically set forth therein and in this Trust Agreement. The Trust Securities shall have no preemptive or similar rights. When issued and delivered to Holders of the Preferred Securities against payment of the purchase price therefor, the Preferred Securities shall be fully paid and nonassessable interests in the Trust. The Holders of the Preferred Securities, in their capacities as such, shall be entitled to the same limitation of personal liability extended to stockholders of private corporations for profit organized under the General Corporation Law of the State of Delaware.

(b) For so long as any Preferred Securities remain Outstanding, upon a Debenture Event of Default, the Debenture Trustee fails or the holders of not less than 25% in principal amount of the outstanding Debentures fail to declare the principal of all of the Debentures to be immediately due and payable, the Holders of at least 25% in Liquidation Amount of the Preferred Securities then Outstanding shall have such right by a notice in writing to the Depositor and the Debenture Trustee; and upon any such declaration such principal amount of and the accrued interest on all of the Debentures shall become immediately due and payable, provided that the payment of principal and interest on such Debentures shall remain subordinated to the extent provided in the Indenture.

(c) For so long as any Preferred Securities remain Outstanding, upon a Debenture Event of Default arising from the failure to pay interest or principal on the Debentures, the Holders of any Preferred Securities then Outstanding shall, to the fullest extent permitted by law, have the right to directly institute proceedings for enforcement of payment to such Holders of principal of or interest on the Debentures having a principal amount equal to the Liquidation Amount of the Preferred Securities of such Holders.

SECTION 601. LIMITATIONS ON VOTING RIGHTS.

(a) Except as provided in this Section 601, in Sections 514, 810 and 1002 and in the Indenture and as otherwise required by law, no Holder of Preferred Securities shall have any right to vote or in any manner otherwise control the administration, operation and management of the Trust or the obligations of the parties hereto, nor shall anything herein set forth, or contained in the terms of the Trust Securities Certificates, be construed so as to constitute the Securityholders from time to time as partners or members of an association.

(b) So long as any Debentures are held by the Property Trustee, the Trustees shall not (i) direct the time, method and place of conducting any proceeding for any remedy available to the Debenture Trustee, or executing any trust or power conferred on the Debenture Trustee with respect to such Debentures; (ii) waive any past default which is waivable under Article VII of the Indenture; (iii) exercise any right to rescind or annul a declaration that the principal of all the Debentures shall be due and payable; or (iv) consent to any amendment, modification or termination of the Indenture or the Debentures, where such consent shall be required, without, in each case, obtaining the prior approval of the Holders of at least a majority in Liquidation Amount of all Outstanding Preferred Securities; provided, however, that where a consent under the Indenture would require the consent of each holder of outstanding Debentures affected thereby, no such consent shall be given by the Property Trustee without the prior written consent of each Holder of Preferred Securities. The Trustees shall not revoke any action previously authorized or approved by a vote of the Holders of the Outstanding Preferred Securities, except when authorized by a subsequent vote of the Holders of the Outstanding Preferred Securities. The Property Trustee shall notify each Holder of the Outstanding Preferred Securities of any notice of default received from the Debenture Trustee with respect to the Debentures. In addition to obtaining the foregoing approvals of the Holders of the Preferred Securities, prior to taking any of the foregoing actions, the Trustees shall, at the expense of the Depositor, obtain an Opinion of Counsel experienced in such matters to the effect that the Trust shall continue to be classified as a grantor trust and not as an association taxable as a corporation for United States federal income tax purposes on account of such action.

(c) If any proposed amendment to the Trust Agreement provides for, or the Trustees otherwise propose to effect, (i) any action that would adversely affect in any material respect the powers, preferences or special rights of the Preferred Securities, whether by way of amendment to the Trust Agreement or otherwise; or (ii) the dissolution, winding-up or termination of the Trust, other than pursuant to the terms of this Trust Agreement, then the Holders of Outstanding Preferred Securities as a class shall be entitled to vote on such amendment or proposal and such amendment or proposal shall not be effective except with the approval of the Holders of at least a majority in Liquidation Amount of the Outstanding Preferred Securities. No amendment to this Trust Agreement may be made if, as a result of such amendment, the Trust would cease to be

-26-

classified as a grantor trust or would be classified as an association taxable as a corporation for United States federal income tax purposes.

SECTION 602. NOTICE OF MEETINGS.

Notice of all meetings of the Preferred Securityholders, stating the time, place and purpose of the meeting, shall be given by the Property Trustee pursuant to Section 1008 to each Preferred Securityholder of record, at his registered address, at least 15 days and not more than 90 days before the meeting.

(b) Preferred Securityholders of record of 50% of the Outstanding Preferred Securities (based upon their aggregate Liquidation Amount), present in person or by proxy, shall constitute a quorum at any meeting of Securityholders.

SECTION 604. VOTING RIGHTS.

Securityholders shall be entitled to one vote for each dollar value of Liquidation Amount represented by their Trust Securities in respect of any matter as to which such Securityholders are entitled to vote (and such dollar value shall be $10 per Preferred Security until such time, if any, as the Liquidation Amount is changed as provided herein).

SECTION 605. PROXIES, ETC.

At any meeting of Securityholders, any Securityholder entitled to vote thereat may vote by proxy, provided that no proxy, shall be voted at any meeting unless it shall have been placed on

-27-

file with the Administrative Trustees, or with such other officer or agent of the Trust as the Administrative Trustees may direct, for verification prior to the time at which such vote shall be taken. When Trust Securities are held jointly by several persons, any one of them may vote at any meeting in person or by proxy in respect of such Trust Securities, but if more than one of them shall be present at such meeting in person or by proxy, and such joint owners or their proxies so present disagree as to any vote to be cast, such vote shall not be received in respect of such Trust Securities. A proxy purporting to be executed by or on behalf of a Securityholder shall be deemed valid unless challenged at or prior to its exercise, and, the burden of proving invalidity shall rest on the challenger. No proxy shall be valid more than three years after its date of execution.

SECTION 606. SECURITYHOLDER ACTION BY WRITTEN CONSENT.

Any action which may be taken by Securityholders at a meeting may be taken without a meeting if Securityholders holding more than a majority of all Outstanding Trust Securities (based upon their aggregate Liquidation Amount) entitled to vote in respect of such action (or such larger proportion thereof as shall be required by any express provision of this Trust Agreement) shall consent to the action in writing.

SECTION 607. RECORD DATE FOR VOTING AND OTHER PURPOSES.

For the purposes of determining the Securityholders who are entitled to notice of and to vote at any meeting or by written consent, or to participate in any Distribution on the Trust Securities in respect of which a record date is not otherwise provided for in this Trust Agreement, or for the purpose of any other action, the Administrative Trustees may from time to time fix a date, not more than 90 days prior to the date of any meeting of Securityholders or the payment of Distribution or other action, as the case may be, as a record date for the determination of the identity of the Securityholders of record for such purposes.

SECTION 608. ACTS OF SECURITYHOLDERS.

(a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Trust Agreement to be given, made or taken by Securityholders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Securityholders in person or by an agent duly appointed in writing; and, except as otherwise expressly provided herein, such action shall become effective when such instrument or instruments are delivered to an Administrative Trustee. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the "Act" of the Securityholders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Trust Agreement and (subject to Section 801) conclusive in favor of the Trustees, if made in the manner provided in this Section 608.

-28-

(b) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner which any Trustee receiving the same deems sufficient.

(c) The ownership of Preferred Securities shall be proved by the Securities Register.

(d) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Securityholder of any Trust Security shall bind every future Securityholder of the same Trust Security and the Securityholder of every Trust Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustees or the Trust in reliance thereon, whether or not notation of such action is made upon such Trust Security.

(e) Without limiting the foregoing, a Securityholder entitled hereunder to take any action hereunder with regard to any particular Trust Security may do so with regard to all or any part of the Liquidation Amount of such Trust Security or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any part of such Liquidation Amount.

(f) A Securityholder may institute a legal proceeding directly against the Depositor under the Guarantee to enforce its rights under the Guarantee without first instituting a legal proceeding against the Guarantee Trustee (as defined in the Guarantee), the Trust or any Person.

SECTION 609. INSPECTION OF RECORDS.

Upon reasonable notice to the Administrative Trustees and the Property Trustee, the records of the Trust shall be open to inspection and copying by Securityholders and their authorized representatives during normal business hours for any purpose reasonably related to such Securityholder's interest as a Securityholder.

ARTICLE VIII
TRUSTEES

SECTION 801. CERTAIN DUTIES AND RESPONSIBILITIES.

(a) The duties and responsibilities of the Trustees shall be as provided by this Trust Agreement and, in the case of the Property Trustee, by the Trust Indenture Act. Notwithstanding the foregoing, no provision of this Trust Agreement shall require the Trustees to expend or risk their own funds or otherwise incur any financial liability in the performance of any of their duties hereunder, or in the exercise of any of their rights or powers, if they shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to them. No Administrative Trustee nor the Delaware Trustee shall be liable for its act or omissions hereunder except as a result of its own gross negligence or willful misconduct. The Property Trustee's liability shall be determined under the Trust Indenture Act. Whether or not therein expressly so provided, every provision of this Trust Agreement relating to the conduct or affecting the liability of or affording protection to the Trustees shall be subject to the provisions of this Section 801. To the extent that, at law or in equity, the Delaware Trustee or an Administrative Trustee has duties (including fiduciary duties) and liabilities relating thereto to the Trust or to the Securityholders, the Delaware Trustee or such Administrative Trustee shall not be liable to the Trust or to any Securityholder for such Trustee's good faith reliance on the provisions of this Trust Agreement. The provisions of this Trust Agreement, to the extent that

-32-

they restrict the duties and liabilities of the Delaware Trustee or the Administrative Trustees otherwise existing at law or in equity, are agreed by the Depositor and the Securityholders to replace such other duties and liabilities of the Delaware Trustee and the Administrative Trustees, as the case may be.

(b) All payments made by the Property Trustee or a Paying Agent in respect of the Trust Securities shall be made only from the revenue and proceeds from the Trust Property and only to the extent that there shall be sufficient revenue or proceeds from the Trust Property to enable the Property Trustee or a Paying Agent to make payments in accordance with the terms hereof. With respect to the relationship of each Securityholder and the Trustee, each Securityholder, by its acceptance of a Trust Security, agrees that it shall look solely to the revenue and proceeds from the Trust Property to the extent legally available for distribution to it as herein provided and that the Trustees are not personally liable to it for any amount distributable in respect of any Trust Security or for any other liability in respect of any Trust Security. This Section 801(b) does not limit the liability of the Trustees expressly set forth elsewhere in this Trust Agreement or, in the case of the Property Trustee, in the Trust Indenture Act.

(c) No provision of this Trust Agreement shall be construed to relieve the Property Trustee from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that:

(i) the Property Trustee shall not be liable for any error of judgment made in good faith by an authorized officer of the Property Trustee, unless it shall be proved that the Property Trustee was negligent in ascertaining the pertinent facts;

(ii) the Property Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Holders of not less than a majority in Liquidation Amount of the Trust Securities relating to the time, method and place of conducting any proceeding for any remedy available to the Property Trustee, or exercising any trust or power conferred upon the Property Trustee under this Trust Agreement;

(iii) the Property Trustee's sole duty with respect to the custody, safe keeping and physical preservation of the Debentures and the Payment Account shall be to deal with such property in a similar manner as the Property Trustee deals with similar property for its own account, subject to the protections and limitations on liability afforded to the Property Trustee under this Trust Agreement and the Trust Indenture Act;

(iv) the Property Trustee shall not be liable for any interest on any money received by it except as it may otherwise agree with the Depositor and money held by the Property Trustee need not be segregated from other funds held by it except in relation to the Payment Account maintained by the Property Trustee pursuant to Section 301 and except to the extent otherwise required by law; and

-33-

(v) the Property Trustee shall not be responsible for monitoring the compliance by the Administrative Trustees or the Depositor with their respective duties under this Trust Agreement, nor shall the Property Trustee be liable for the negligence, default or misconduct of the Administrative Trustees or the Depositor.

SECTION 802. CERTAIN NOTICES.

(a) Within 5 Business Days after the occurrence of any Event of Default actually known to the Property Trustee, the Property Trustee shall transmit, in the manner and to the extent provided in Section 1008, notice of such Event of Default to the Securityholders, the Administrative Trustees and the Depositor, unless such Event of Default shall have been cured or waived. For purposes of this Section 802 the term "Event of Default" means any event that is, or after notice or lapse of time or both would become, an Event of Default.

(b) The Administrative Trustees shall transmit, to the Securityholders in the manner and to the extent provided in Section 1008, notice of the Depositor's election to begin or further extend an Extension Period on the Debentures (unless such election shall have been revoked), and of any election by the Depositor to accelerate the Maturity Date of the Debentures within the time specified for transmitting such notice to the holders of the Debentures pursuant to the Indenture as originally executed.

SECTION 803. CERTAIN RIGHTS OF PROPERTY TRUSTEE.

Subject to the provisions of Section 801:

(a) the Property Trustee may rely and shall be protected in acting or refraining from acting in good faith upon any resolution, Opinion of Counsel, certificate, written representation of a Holder or transferee, certificate of auditors or any other certificate, statement, instrument, opinion, report, notice, request, consent, order, appraisal, bond, debenture, note, other evidence of indebtedness or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties;

(b) if (i) in performing its duties under this Trust Agreement the Property Trustee is required to decide between alternative courses of action; or
(ii) in construing any of the provisions of this Trust Agreement the Property Trustee finds the same ambiguous or inconsistent with other provisions contained herein; or (iii) the Property Trustee is unsure of the application of any provision of this Trust Agreement, then, except as to any matter as to which the Preferred Securityholders are entitled to vote under the terms of this Trust Agreement, the Property Trustee shall deliver a notice to the Depositor requesting written instructions of the Depositor as to the course of action to be taken and the Property Trustee shall take such action, or refrain from taking such action, as the Property Trustee shall be instructed in writing to take, or to refrain from taking, by the Depositor; provided, however, that if the Property Trustee does not receive such instructions of the Depositor within 10 Business Days after it has delivered such notice, or such reasonably shorter period of time set forth in such notice (which to the extent practicable shall not

-34-

be less than 2 Business Days), it may, but shall be under no duty to, take or refrain from taking such action not inconsistent with this Trust Agreement as it shall deem advisable and in the best interests of the Securityholders, in which event the Property Trustee shall have no liability except for its own bad faith, negligence or willful misconduct;

(c) any direction or act of the Depositor or the Administrative Trustees contemplated by this Trust Agreement shall be sufficiently evidenced by an Officers' Certificate;

(d) whenever in the administration of this Trust Agreement, the Property Trustee shall deem it desirable that a matter be established before undertaking, suffering or omitting any action hereunder, the Property Trustee (unless other evidence is herein specifically prescribed) may, in the absence of bad faith on its part, request and conclusively rely upon an Officer's Certificate which, upon receipt of such request, shall be promptly delivered by the Depositor or the Administrative Trustees;

(e) the Property Trustee shall have no duty to see to any recording, filing or registration of any instrument (including any financing or continuation statement, any filing under tax or securities laws or any filing under tax or securities laws) or any rerecording, refiling or reregistration thereof;

(f) the Property Trustee may consult with counsel of its choice (which counsel may be counsel to the Depositor or any of its Affiliates) and the advice of such counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon and, in accordance with such advice, such counsel may be counsel to the Depositor or any of its Affiliates, and may include any of its employees; the Property Trustee shall have the right at any time to seek instructions concerning the administration of this Trust Agreement from any court of competent jurisdiction;

(g) the Property Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Trust Agreement at the request, order or direction of any of the Securityholders pursuant to this Trust Agreement, unless such Securityholders shall have offered to the Property Trustee reasonable security or indemnity against the costs, expenses and liabilities which might be incurred by it in compliance with such request, order or direction; nothing contained herein shall, however, relieve the Property Trustee of the obligation, upon the occurrence of an Event of Default (that has not been cured or waived) to exercise with respect to the Debentures, such of the rights and powers vested in it by this Trust Agreement, and to use the same degree of care and skill in their exercise as a prudent man would exercise or use under the circumstances in the conduct of his own affairs;

(h) the Property Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval, bond, debenture, note or other evidence of indebtedness or other paper or document, unless requested in writing to do so by one or more Securityholders, but the

-35-

Property Trustee may make such further inquiry or investigation into such facts or matters as it may see fit;

(i) the Property Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through its agents or attorneys, provided that the Property Trustee shall be responsible for its own negligence or recklessness with respect to selection of any agent or attorney appointed by it hereunder;

(j) whenever in the administration of this Trust Agreement the Property Trustee shall deem it desirable to receive instructions with respect to enforcing any remedy or right or taking any other action hereunder the Property Trustee (i) may request instructions from the Holders of the Trust Securities which instructions may only be given by the Holders of the same proportion in Liquidation Amount of the Trust Securities as would be entitled to direct the Property Trustee under the terms of the Trust Securities in respect of such remedy, right or action; (ii) may refrain from enforcing such remedy or right or taking such other action until such instructions are received; and (iii) shall be protected in acting in accordance with such instructions; and

(k) except as otherwise expressly provided by this Trust Agreement, the Property Trustee shall not be under any obligation to take any action that is discretionary under the provisions of this Trust Agreement. No provision of this Trust Agreement shall be deemed to impose any duty or obligation on the Property Trustee to perform any act or acts or exercise any right, power, duty or obligation conferred or imposed on it, in any jurisdiction in which it shall be illegal, or in which the Property Trustee shall be unqualified or incompetent in accordance with applicable law, to perform any such act or acts, or to exercise any such right, power, duty or obligation. No permissive power or authority available to the Property Trustee shall be construed to be a duty.

SECTION 804. NOT RESPONSIBLE FOR RECITALS OR USE OF PROCEEDS.

The Recitals contained herein and in the Trust Securities Certificates shall be taken as the statements of the Trust, and the Trustees do not assume any responsibility for their correctness. The Trustees shall not be accountable for the use or application by the Depositor of the proceeds of the Debentures.

SECTION 805. MAY HOLD SECURITIES.

Any Trustee or any other agent of any Trustee or the Trust, in its individual or any other capacity, may become the owner or pledgee of Trust Securities and, subject to Sections 808 and 813 and except as provided in the definition of the term "Outstanding" in Article I, may otherwise deal with the Trust with the same rights it would have if it were not a Trustee or such other agent.

SECTION 806. COMPENSATION; INDEMNITY; FEES.

The Depositor agrees:

-36-

(a) to pay to the Trustees from time to time reasonable compensation for all services rendered by them hereunder (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust);

(b) except as otherwise expressly provided herein, to reimburse the Trustees upon request for all reasonable expenses, disbursements and advances incurred or made by the Trustees in accordance with any provision of this Trust Agreement (including the reasonable compensation and the expenses and disbursements of its agents and counsel), except any such expense, disbursement or advance as may be attributable to such Trustee's negligence, bad faith or willful misconduct (or, in the case of the Administrative Trustees or the Delaware Trustee, any such expense, disbursement or advance as may be attributable to its, his or her gross negligence, bad faith or willful misconduct); and

(c) to indemnify each of the Trustees or any predecessor Trustee for, and to hold the Trustees harmless against, any loss, damage, claims, liability, penalty or expense incurred without negligence or bad faith on its part, arising out of or in connection with the acceptance or administration of this Trust Agreement, including the costs and expenses of defending itself against any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder, except any such expense, disbursement or advance as may be attributable to such Trustee's negligence, bad faith or willful misconduct (or, in the case of the Administrative Trustees or the Delaware Trustee, any such expense, disbursement or advance as may be attributable to its, his or her gross negligence, bad faith or willful misconduct).

No Trustee may claim any Lien on any Trust Property as a result of any amount due pursuant to this Section 806.

If any such Person publishes reports of condition at least annually, pursuant to law or to the requirements of its supervising or examining authority, then for the purposes of this Section 807, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published.

SECTION 808. CONFLICTING INTERESTS.

If the Property Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Property Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Trust Agreement.

SECTION 809. CO-TRUSTEES AND SEPARATE TRUSTEE.

(a) Unless an Event of Default shall have occurred and be continuing, at any time or times, for the purpose of meeting the legal requirements of the Trust Indenture Act or of any jurisdiction in which any part of the Trust Property may at the time be located, the Depositor shall have power to appoint, and upon the written request of the Property Trustee, the Depositor shall for such purpose join with the Property Trustee in the execution, delivery and performance of all instruments and agreements necessary or proper to appoint, one or more Persons approved by the Property Trustee either to act as co-trustee, jointly with the Property Trustee, of all or any part of such Trust Property, or to the extent required by law to act as separate trustee of any such property, in either case with such powers as may be provided in the instrument of appointment, and to vest in such Person or Persons in the capacity aforesaid, any property, title, right or power deemed necessary or desirable, subject to the other provisions of this Section 809. If the Depositor does not join in such appointment within 15 days after the receipt by it of a request so to do, or in case a Debenture Event of Default has occurred and is continuing, the Property Trustee alone shall have power to make such appointment. Any co-trustee or separate trustee appointed pursuant to this Section 809 shall either be (i) a natural person who is at least 21 years of age and a resident of the United States; or (ii) a legal entity with its principal place of business in the United States that shall act through one or more persons authorized to bind such entity.

(b) Should any written instrument from the Depositor be required by any co-trustee or separate trustee so appointed for more fully confirming to such co-trustee or separate trustee such property, title, right, or power, any and all such instruments shall, on request, be executed, acknowledged, and delivered by the Depositor.

(c) Every co-trustee or separate trustee shall, to the extent permitted by law, but to such extent only, be appointed subject to the following terms, namely:

(i) The Trust Securities shall be executed and delivered and all rights, powers, duties and obligations hereunder in respect of the custody of securities, cash and other personal property held by, or required to be deposited or pledged with, the Trustees

-38-

specified hereunder, shall be exercised, solely by such Trustees and not by such co-trustee or separate trustee.

(ii) The rights, powers, duties and obligations hereby conferred or imposed upon the Property Trustee in respect of any property covered by such appointment shall be conferred or imposed upon and exercised or performed by the Property Trustee or by the Property Trustee and such co-trustee or separate trustee jointly, as shall be provided in the instrument appointing such co-trustee or separate trustee, except to the extent that under any law of any jurisdiction in which any particular act is to be performed, the Property Trustee shall be incompetent or unqualified to perform such act, in which event such rights, powers, duties and obligations shall be exercised and performed by such co-trustee or separate trustee.

(iii) The Property Trustee at any time, by an instrument in writing executed by it, with the written concurrence of the Depositor, may accept the resignation of or remove any co-trustee or separate trustee appointed under this Section 809, and, in case a Debenture Event of Default has occurred and is continuing, the Property Trustee shall have the power to accept the resignation of, or remove, any such co-trustee or separate trustee without the concurrence of the Depositor. Upon the written request of the Property Trustee, the Depositor shall join with the Property Trustee in the execution, delivery and performance of all instruments and agreements necessary or proper to effectuate such resignation or removal. A successor to any co-trustee or separate trustee so resigned or removed may be appointed in the manner provided in this Section 809.

SECTION 810. RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

(a) Except as otherwise provided herein, no resignation or removal of any Trustee (the "Relevant Trustee") and no appointment of a successor Trustee pursuant to this Article VIII shall become effective until the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of Section 811.

(b) Subject to the immediately preceding paragraph, the Relevant Trustee may resign at any time with respect to the Trust Securities by giving written notice thereof to the Securityholders. If the instrument of acceptance by the successor Trustee required by Section

-39-

811 shall not have been delivered to the Relevant Trustee within 30 days after the giving of such notice of resignation, the Relevant Trustee may petition, at the expense of the Depositor, any court of competent jurisdiction for the appointment of a successor Relevant Trustee with respect to the Trust Securities.

(c) Unless a Debenture Event of Default shall have occurred and be continuing, any Trustee may be removed at any time by Act of the Common Securityholder. If a Debenture Event of Default shall have occurred and be continuing, the Property Trustee or the Delaware Trustee, or both of them, may be removed at such time by Act of the Holders of a majority in Liquidation Amount of the Preferred Securities, delivered to the Relevant Trustee (in its individual capacity and on behalf of the Trust). An Administrative Trustee may be removed by the Common Securityholder at any time.

(d) If any Trustee shall resign, be removed or become incapable of acting as Trustee, or if a vacancy shall occur in the office of any Trustee for any cause, at a time when no Debenture Event of Default shall have occurred and be continuing, the Common Securityholder, by Act of the Common Securityholder delivered to the retiring Trustee, shall promptly appoint a successor Trustee or Trustees with respect to the Trust Securities and the Trust, and the successor Trustee shall comply with the applicable requirements of Section 811. If the Property Trustee or the Delaware Trustee shall resign, be removed or become incapable of continuing to act as the Property Trustee or the Delaware Trustee, as the case may be, at a time when a Debenture Event of Default shall have occurred and is continuing, the Preferred Securityholders, by Act of the Securityholders of a majority in Liquidation Amount of the Preferred Securities then Outstanding delivered to the retiring Relevant Trustee, shall promptly appoint a successor Relevant Trustee or Trustees with respect to the Trust Securities and the Trust, and such successor Trustee shall comply with the applicable requirements of Section 811. If an Administrative Trustee shall resign, be removed or become incapable of acting as Administrative Trustee, at a time when a Debenture Event of Default shall have occurred and be continuing, the Common Securityholder, by Act of the Common Securityholder delivered to an Administrative Trustee, shall promptly appoint a successor Administrative Trustee or Administrative Trustees with respect to the Trust Securities and the Trust, and such successor Administrative Trustee or Administrative Trustees shall comply with the applicable requirements of Section 811. If no successor Relevant Trustee with respect to the Trust Securities shall have been so appointed by the Common Securityholder or the Preferred Securityholders and accepted appointment in the manner required by Section 811, any Securityholder who has been a Securityholder of Trust Securities for six consecutive months on behalf of himself and all others similarly situated may petition a court of competent jurisdiction for the appointment of a successor Relevant Trustee with respect to the Trust Securities.

(e) The Property Trustee shall give notice of each resignation and each removal of a Trustee and each appointment of a successor Trustee to all Securityholders in the manner provided in Section 1008 and shall give notice to the Depositor. Each notice shall include the name of the successor Relevant Trustee and the address of its Corporate Trust Office if it is the Property Trustee.

-40-

(f) Notwithstanding the foregoing or any other provision of this Trust Agreement, in the event any Administrative Trustee or a Delaware Trustee who is a natural person dies or becomes, in the opinion of the Depositor, incompetent or incapacitated, the vacancy created by such death, incompetence or incapacity may be filled by (a) the unanimous act of remaining Administrative Trustees if there are at least two of them; or (b) otherwise by the Depositor (with the successor in each case being a Person who satisfies the eligibility requirement for Administrative Trustees set forth in Section 807).

SECTION 811. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

(a) In case of the appointment hereunder of a successor Relevant Trustee with respect to the Trust Securities and the Trust, the retiring Relevant Trustee and each successor Relevant Trustee with respect to the Trust Securities shall execute and deliver an instrument hereto wherein each successor Relevant Trustee shall accept such appointment and which shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Relevant Trustee all the rights, powers, trusts and duties of the retiring Relevant Trustee with respect to the Trust Securities and the Trust and upon the execution and delivery of such instrument the resignation or removal of the retiring Relevant Trustee shall become effective to the extent provided therein and each such successor Relevant Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Relevant Trustee with respect to the Trust Securities and the Trust; but, on request of the Trust or any successor Relevant Trustee such retiring Relevant Trustee shall duly assign, transfer and deliver to such successor Relevant Trustee all Trust Property, all proceeds thereof and money held by such retiring Relevant Trustee hereunder with respect to the Trust Securities and the Trust.

(b) Upon request of any such successor Relevant Trustee, the Trust shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Relevant Trustee all such rights, powers and trusts referred to in the immediately preceding paragraph, as the case may be.

(c) No successor Relevant Trustee shall accept its appointment unless at the time of such acceptance such successor Relevant Trustee shall be qualified and eligible under this Article VIII.

SECTION 812. MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

Any Person into which the Property Trustee, the Delaware Trustee or any Administrative Trustee may be merged or converted or with which it may be consolidated, or any Person resulting from any merger, conversion or consolidation to which such Relevant Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of such Relevant Trustee, shall be the successor of such Relevant Trustee hereunder, provided such Person shall be otherwise qualified and eligible under this Article VIII, without the execution or filing of any paper or any further act on the part of any of the parties hereto.

-41-

SECTION 813. PREFERENTIAL COLLECTION OF CLAIMS AGAINST DEPOSITOR OR TRUST.

If and when the Property Trustee or the Delaware Trustee shall be or become a creditor of the Depositor or the Trust (or any other obligor upon the Debentures or the Trust Securities), the Property Trustee or the Delaware Trustee, as the case may be, shall be subject to and shall take all actions necessary in order to comply with the provisions of the Trust Indenture Act regarding the collection of claims against the Depositor or Trust (or any such other obligor).

SECTION 814. REPORTS BY PROPERTY TRUSTEE.

(a) The Property Trustee shall transmit to Securityholders such reports concerning the Property Trustee, its actions under this Trust Agreement and the property and funds in its possession as Property Trustee as may be required pursuant to the Trust Indenture Act at the times and in the manner provided pursuant thereto.

(b) A copy of each such report shall, at the time of such transmission to Holders, be filed by the Property Trustee with The Nasdaq Stock Market's National Market, and each national securities exchange or other organization upon which the Trust Securities are listed, and also with the Commission and the Depositor.

SECTION 815. REPORTS TO THE PROPERTY TRUSTEE.

The Depositor and the Administrative Trustees on behalf of the Trust shall provide to the Property Trustee such documents, reports and information as required by Section 314 of the Trust Indenture Act (if any) and the compliance certificate required by Section 314(a) of the Trust Indenture Act in the form, in the manner and at the times required by Section 314 of the Trust Indenture Act.

SECTION 816. EVIDENCE OF COMPLIANCE WITH CONDITIONS PRECEDENT.

Each of the Depositor and the Administrative Trustees on behalf of the Trust shall provide to the Property Trustee such evidence of compliance with any conditions precedent, if any, provided for in this Trust Agreement that relate to any of the matters set forth in Section 314(c) of the Trust Indenture Act. Any certificate or opinion required to be given by an officer pursuant to
Section 314(c)(1) of the Trust Indenture Act shall be given in the form of an Officers' Certificate.

SECTION 817. NUMBER OF TRUSTEES.

-42-

(a) The number of Trustees shall be five, provided that the Holder of all of the Common Securities by written instrument may increase or decrease the number of Administrative Trustees. The Property Trustee and the Delaware Trustee may be the same Person.

(b) If a Trustee ceases to hold office for any reason and the number of Administrative Trustees is not reduced pursuant to Section 817(a), or if the number of Trustees is increased pursuant to Section 817(a), a vacancy shall occur. The vacancy shall be filled with a Trustee appointed in accordance with
Section 810.

(c) The death, resignation, retirement, removal, bankruptcy, incompetence or incapacity to perform the duties of a Trustee shall not operate to annul the Trust.

Notice of liquidation shall be given by the Property Trustee by first-class mail, postage prepaid, mailed not later than 30 nor more than 60 days prior to the Liquidation Date to each Holder of Trust Securities at such Holder's address appearing in the Securities Register. All notices of liquidation shall:

(i) state the Liquidation Date;

(d) In the event that, notwithstanding the other provisions of this
Section 904, whether because of an order for dissolution entered by a court of competent jurisdiction or otherwise, distribution of the Debentures in the manner provided herein is determined by the Property Trustee not to be practical, the Trust Property shall be liquidated, and the Trust shall be dissolved by the Property Trustee in such manner as the Property Trustee determines. In such event, on the date of the dissolution of the Trust, Securityholders shall be entitled to receive out of the assets of the Trust available for distribution to Securityholders, after satisfaction of liabilities to creditors of the Trust as provided by applicable law, (including, without limitation, after paying or making reasonable provision to pay all claims and obligations of the Trust in accordance with Section 3808(e) of the Delaware Business Trust Act), an amount equal to the Liquidation Amount per Trust Security plus accumulated and unpaid Distributions thereon to the date of payment (such amount being the "Liquidation Distribution"). If, upon any such dissolution the Liquidation Distribution can be paid only in part because the Trust has insufficient assets available to pay in

-45-

full the aggregate Liquidation Distribution, then, subject to the next succeeding sentence, the amounts payable by the Trust on the Trust Securities shall be paid on a pro rata basis (based upon Liquidation Amounts, subject to
Section 407). The Holder of the Common Securities shall be entitled to receive Liquidation Distributions upon any such dissolution pro rata (determined as aforesaid) with Holders of Preferred Securities, except that, if a Debenture Event of Default has occurred and is continuing, the Preferred Securities shall have a priority over the Common Securities.

The Trust may not merge with or into, consolidate, amalgamate, or be replaced by, or convey, transfer or lease its properties and assets substantially as an entirety to any corporation or other Person, except pursuant to this Section 905. At the request of the Depositor, with the consent of the Administrative Trustees and without the consent of the Holders of the Preferred Securities, the Property Trustee or the Delaware Trustee, the Trust may merge with or into, consolidate, amalgamate, be replaced by or convey, transfer or lease its properties and assets substantially as an entirety to a trust organized as such under the laws of any State; provided, that (i) such successor entity either (a) expressly assumes all of the obligations of the Trust with respect to the Preferred Securities; or (b) substitutes for the Preferred Securities other securities having substantially the same terms as the Preferred Securities (the "Successor Securities") so long as the Successor Securities rank the same as the Preferred Securities rank in priority with respect to distributions and payments upon liquidation, redemption and otherwise; (ii) the Depositor expressly appoints a trustee of such successor entity possessing substantially the same powers and duties as the Property Trustee as the holder of the Debentures; (iii) the Successor Securities are listed or traded, or any Successor Securities shall be listed or traded upon notification of issuance, on any national securities exchange or other organization on which the Preferred Securities are then listed, if any; (iv) such merger, consolidation, amalgamation, replacement, conveyance, transfer or lease does not adversely affect the rights, preferences and privileges of the Holders of the Preferred Securities (including any Successor Securities) in any material respect; (v) prior to such merger, consolidation, amalgamation, replacement, conveyance, transfer or lease, the Depositor has received an Opinion of Counsel to the effect that (a) such merger, consolidation, amalgamation, replacement, conveyance, transfer or lease does not adversely affect the rights, preferences and privileges of the Holders of the Preferred Securities (including any Successor Securities) in any material respect; and (b) following such merger, consolidation, amalgamation, replacement, conveyance, transfer or lease, neither the Trust nor such successor entity shall be required to register as an "investment company" under the Investment Company Act; and (vi) the Depositor owns all of the Common Securities of such successor entity and guarantees the obligations of such successor entity under the Successor Securities at least to the extent provided by the Guarantee, the Debentures, the Indenture, this Trust Agreement and the Expense Agreement. Notwithstanding the foregoing, the Trust shall not, except with the consent of Holders of 100% in Liquidation Amount of the Preferred Securities, consolidate, amalgamate, merge with or into, or be replaced by or convey, transfer or lease its properties and assets substantially as an entirety to any other Person or permit any other

-46-

Person to consolidate, amalgamate, merge with or into, or replace it if such consolidation, amalgamation, merger or replacement would cause the Trust or the successor entity to be classified as other than a grantor trust for United States federal income tax purposes.
