Report of Independent Registered Public Accounting Firm

The Board of Directors
Century Bancorp, Inc. 401(k) Plan:

We have audited the accompanying statements of net assets available for plan benefits of Century Bancorp, Inc. 401(k) Plan (the Plan) as of December 31, 2002 and 2001, and the related statements of changes in net assets available for plan benefits for the years then ended. These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the 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 financial statements referred to above present fairly, in all material respects, the net assets available for plan benefits of the Plan as of December 31, 2002 and 2001, and the changes in net assets available for plan benefits for the years then ended in conformity with U.S. generally accepted accounting principles.

Our audits were performed for the purpose of forming an opinion on the basic financial statements, taken as a whole. The supplemental schedule of assets held at end of year is presented for purposes of additional analysis and is not a required part of the basic financial statements but is supplementary information required by the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. The supplemental schedule is the responsibility of the Plan’s management. The supplemental schedule has been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole.

(1)		Description of Plan
		The following description of the Century Bancorp, Inc. 401(k) Flan (the Plan) is provided for general information purposes. Participants should refer to the Plan document for more detailed information.

	(a)		General
			The Century Bancorp, Inc. 401(k) Plan was established on October 1, 1996 for the purpose of providing a medium for eligible employees to supplement their retirement income through salary reduction arrangements on a tax-deferred basis, and is established for the exclusive benefit of the employees and their beneficiaries. The Plan is a defined contribution savings plan for all employees of Century Bancorp, Inc. who have attained age twenty-one and completed one year of service. Century Bancorp, Inc. pays all general administrative expenses of the Plan. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA).
	(b)		Contributions
			Each participant of the Plan may enter into an enrollment agreement under which participants agree to reduce their compensation by a specified percent. The percentage shall not be less than 2% nor more than 15% of the participant’s annual compensation, subject to IRS limitations. The employer pays a matching contribution on behalf of each member who has made a salary reduction contribution during such Plan year in an amount equal to $0.25 on each dollar contributed up to 4% of compensation prior to September 1, 2001 and $0.33 on each dollar contributed up to 6% of compensation subsequent to September 1, 2001.
	(c)		Vesting
			Participants are fully vested in all benefits.
	(d)		Payment of Benefits
			Under the terms of the Plan, participants retiring at or after age 59 1/2 are eligible to receive the entire balances in all of the accounts maintained for such participants in a lump sum payment. Participants terminating employment prior to retirement receive their entire account balance as a lump sum payment, with applicable taxes withheld, or as a rollover into another qualified plan. In the event of death, the full value of the participant’s account is payable to the designated beneficiary in a lump sum.
	(e)		Participants’ Loans
			Participant loans may be granted by the Plan Administrator on a uniform and nondiscriminatory basis, upon written request by a participant. The minimum loan amount is $1,000. The maximum loan amount cannot exceed the lesser of 50% of the participant’s account balance or $50,000. Loans are repaid through a payroll deduction and generally within five years.

Summary of Significant Accounting Policies

	(a)		Basis of Presentation
			The accompanying financial statements of the Plan have been prepared on the accrual basis of accounting and present the net assets available for plan benefits and changes in those net assets.
	(b)		Investment Valuation and Income Recognition
			Marketable investments are stated at fair value. The fair value of marketable investments is based on quoted market prices. Money market fund investments are stated at cost, which approximates fair value. Participant loans are stated at cost which approximates fair value.
			Securities transactions are recognized on the trade date (the date the order to buy or sell is executed). Dividend income is recorded on the ex-dividend date. Realized gains and losses are determined on the average cost method.
	(c)		Management Estimates
			The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates.
	(d)		Benefits
			Benefits are recorded when paid.
	(e)		Investment Options
			The Plan offers investment options among various funds. Participants may elect to have contributions to their account invested in one or a combination of the following investment options:

	1.		Galaxy Institutional Treasury Money Market Fund: a money market fund which seeks to preserve principal value and maintain a high degree of liquidity while providing current income.
	2.		Liberty Quality Plus Bond — Class Z: a bond fund which invests in high quality, short-term bonds and seeks to achieve price stability.
	3.		Janus Fund: a long-term growth fund which seeks long-term growth of capital in a manner consistent with the preservation of capital.
