Savings Banks Employees Retirement Association

We have audited the accompanying statement of net assets available for benefits of the Savings Banks Employees Retirement Association 401(k) Plan as adopted by Century Bancorp, Inc. (the “Plan”), as of December 31, 2012, and the related statement of changes in net assets available for benefits for the year ended December 31, 2012. 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 audit.

We conducted our audit 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 audit provides 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 benefits of the Plan as of December 31, 2012, and the changes in net assets available for benefits for the year ended December 31, 2012, in conformity with accounting principles generally accepted in the United States of America.

Our audit was performed for the purpose of forming an opinion on the financial statements as a whole. The supplemental Schedule H, Line 4i, Schedule of Assets (Held at End of Year) as of December 31, 2012 is presented for the purpose of additional analysis and is not a required part of the 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. This supplemental schedule is the responsibility of the Plan’s management. The supplemental schedule has been subjected to the auditing procedures applied in the audit 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.

FOR THE YEARS ENDED DECEMBER 31, 2012 AND 2011

NOTE 1 - DESCRIPTION OF THE PLAN

The following description of the Savings Banks Employees Retirement Association (“SBERA”) 401(k) Plan as adopted by Century Bancorp, Inc. (the “Plan”) is provided for general information purpose only. Participants should refer to the Plan Agreement for more complete information.

GENERAL

The Plan is a defined contribution plan covering substantially all employees of Century Bancorp, Inc (the “Bank”). It is subject to the provisions of the Employee Retirement Income Security Act of 1974 (“ERISA”).

The Plan is a member of the SBERA Common Collective Trust (the “Trust”). Under the trust agreement, the Plan owns a portion of the net assets of the Trust, which represents its interest in the Trust. Within the Trust, each Plan’s assets are jointly invested and the return on the assets is allocated to each Plan based on the percentage of ownership each Plan has in the Trust’s net assets. Contributions made to and benefits paid from the Trust for the Plan result in increases or decreases in the Plan’s ownership percentage in the net assets of the Trust.

ELIGIBILITY

To become eligible for participation, an employee must be at least age 21.

CONTRIBUTIONS

Each year, participants may contribute to the Plan a percentage of pretax annual compensation, as defined in the Plan, up to the maximum amount allowable under the provisions of the Internal Revenue Code. Participants who have attained age 50 before the end of the plan year are eligible to make catch-up contributions. Participants may also contribute amounts representing distributions from other qualified plans or defined contribution plans. Participants direct the investment of their contributions into various investment options offered by the Plan.

The Bank’s contributions to the Plan are determined by its Board of Directors. Contributions are subject to certain limitations. Total contributions made by the Bank to the Plan were $306,086 and $256,430 in 2012 and 2011, respectively.

NOTE 1 - DESCRIPTION OF THE PLAN (CONTINUED)

PARTICIPANT ACCOUNTS

Each participant’s account is credited with the participant’s contribution and an allocation of (a) the Bank’s contributions and (b) Plan earnings. Allocations are based on participant’s earnings or account balances, as defined. The benefit to which a participant is entitled is the benefit that can be provided from the participant’s vested account.

INVESTMENTS

The Plan currently offers the following investment options to participants:

Equity Account:

This Account seeks to provide capital appreciation through a professionally managed, diversified portfolio of domestic and international stocks.

Index 500 Account:

This Account attempts to provide investment results that parallel the performance of the Standard & Poor’s 500 Composite Stock Price Index.

Small Cap Growth Account:

This Account seeks long-term growth by investing primarily in common stocks of small to medium sized companies that the investment managers believe have a potential for capital appreciation significantly greater than that of the market averages.

International Equity Account:

This Account seeks to provide long-term capital appreciation by investing in foreign equity securities.

Small Cap Value Account:

This Account utilizes a highly disciplined, bottom-up value approach to investing. This process is intended to generate excess returns primarily through stock selection.

NOTE 1 - DESCRIPTION OF THE PLAN (CONTINUED)

INVESTMENTS (CONTINUED)

Large Cap Value Account:

This Account’s investment philosophy combines detailed fundamental research, bottom-up stock selection and portfolio construction, and disciplined management of portfolio volatility to achieve strong risk-adjusted returns over full market cycles.

Large Cap Growth Account:

This Account uses a highly disciplined, mathematical investment strategy designed to seek long-term returns in excess of the target benchmark, while reducing the risk of significant under performance.

Life Path Accounts:

These Accounts are intended for participants who would rather leave their 401(k) account asset allocation decisions to a professional investment manager. Each Account utilizes a predetermined mix of specific asset classes with frequent re-balancing back to the fund’s target allocation.

All Asset Account:

The objective of the All Asset Account is to produce returns which are 5% above the Consumer Price Index (CPI). The strategy is designed as a “fund of funds” that allocates its assets among a group of PIMCO funds. The All Asset Account rebalances among the funds as real return values shift in the market.

The SBERA Account:

The SBERA Account is designed to provide results that parallel the performance of the SBERA Defined Benefit Plan Assets. Given this objective, the Account is expected to provide investors with long-term growth of capital and income. The SBERA Account provides investors with great diversification and significantly less risk than a more concentrated portfolio.

INVESTMENTS (CONTINUED)

Money Market Account:

This Account seeks to provide income consistent with the preservation of principal. This Account invests solely in U.S. Treasury or agency obligations with maturities of six months or less.

Bond Account:

This Account seeks to provide income consistent with U.S. Investment grade bond market returns. The Account will be invested in U.S. Government securities and agencies, mortgage pass-through securities, high quality corporate securities, debt and money market instruments. A prudent amount may be invested in below investment grade corporate bonds, foreign debt instruments and long-dated maturities.

Bank Shares:

Participants may allocate any portion of their contributions to purchase Class A common shares of Century Bancorp, Inc. Participants are subject to restrictions on trading during blackout periods and other reporting requirements of the Securities and Exchange Commission. Investments in Century Bancorp, Inc.’s common stock amounted to $1,004,675 and $848,929 at December 31, 2012 and 2011, respectively. Because the Bank is the Plan Sponsor, transactions involving Century Bancorp, Inc.’s common stock qualify as party-in-interest transactions. All of these transactions are exempt from the prohibited transaction rules.

VESTING

Participants are vested immediately in their contributions plus actual earnings thereon. Vesting in the Bank’s contribution portion of their accounts plus earnings thereon is based on years of continuous service. A participant is 100% vested after five years of credited service.

NOTES RECEIVABLE FROM PARTICIPANTS

Participants may borrow from their fund accounts a minimum of $1,000 up to a maximum equal to the lesser of $50,000 or 50 percent of their account balance. The loans are secured by the balance in the participant’s account and bear interest at rates that range from 4.25% to 8.25% which are commensurate with local prevailing rates, as determined by the plan administrator. Principal and interest is paid ratably through payroll deductions.

PAYMENT OF BENEFITS

On termination of service due to death, disability or retirement, a participant may elect to receive an amount equal to the value of the participant’s vested interest in his or her account in either a lump-sum amount or in periodic installments. For termination of service due to other reasons, a participant may receive the value of the vested interest in his or her account as a lump-sum distribution.

HARDSHIP WITHDRAWALS

The Plan allows participants to make hardship withdrawals, provided certain conditions are met, as defined in the Plan Agreement.

FORFEITED ACCOUNTS

At December 31, 2012 and 2011, forfeited nonvested accounts totaled $812 and $0, respectively. These accounts are used to reduce future employer contributions. For the years ended December 31, 2012 and 2011, employer contributions were reduced by $3,557 and $20,379, respectively.

NOTE 2 - SUMMARY OF ACCOUNTING POLICIES

BASIS OF ACCOUNTING

The financial statements of the Plan are prepared on the accrual basis of accounting.

USE OF ESTIMATES

The preparation of financial statements, in accordance with accounting principles generally accepted in the United States of America, requires the Plan administrator to make estimates and assumptions that affect the reported amounts of assets and liabilities and changes therein, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates.

INVESTMENT VALUATION AND INCOME RECOGNITION

The Plan’s interest in the Trust is reported at fair value. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. See Note 4 for discussion of fair value measurements.

FOR THE YEARS ENDED DECEMBER 31, 2012 AND 2011

NOTE 2 - SUMMARY OF ACCOUNTING POLICIES (CONTINUED)

INVESTMENT VALUATION AND INCOME RECOGNITION (CONTINUED)

Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date. Net investment income includes interest, dividend income and the Plan’s gains and losses on investments bought and sold as well as held during the year. The Plan’s sole investment at December 31, 2012 and 2011 is its interest in the Trust. Consequently, it recognizes investment income based on its percentage of interest in the Trust.

NOTES RECEIVABLE FROM PARTICIPANTS

Notes receivable from participants are measured at their unpaid principal balance plus any accrued but unpaid interest. Interest income is recorded on the accrual basis. No allowance for credit losses has been recorded as of December 31, 2012 or 2011. Delinquent notes receivable from participants are recorded as a distribution based upon the terms of the Plan Agreement.

PAYMENT OF BENEFITS

Benefits are recorded when paid.

ADMINISTRATIVE EXPENSES

Administrative expenses are paid directly by the Trust and are reflected in the Plan’s share of the Trust net investment activity.

SUBSEQUENT EVENTS

The Plan has evaluated subsequent events through July 15, 2013, which is the date the financial statements were available to be issued. No events requiring recognition or disclosure in the financial statements were identified.

NOTE 3 - INVESTMENT- INTEREST IN SBERA COMMON COLLECTIVE TRUST (THE “TRUST”)

All of the Plan’s investments are in the Trust, which was established for the investment of assets of the Plan and several other member bank sponsored retirement plans. Each participating retirement plan has an undivided interest in the Trust. The assets of the Trust are held by several custodians.

The value of the Plan’s interest in the Trust is based on the beginning of year value of the Plan’s interest in the Trust plus actual contributions and allocated investment income less actual distributions and allocated administrative expenses. At December 31, 2012 and 2011, the Plan’s interest in the Trust was approximately 1.28% and 1.25%, respectively. Investment income and administrative expenses relating to the Trust are allocated to the individual plans based upon average monthly balances invested by each plan.

NOTE 4 - FAIR VALUE MEASUREMENTS

FASB ASC 820 provides the framework for measuring fair value. That framework provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy under FASB ASC 820 are described as follows:


Level 1		Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that management has the ability to access.

Level 2		Inputs to the valuation methodology include quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in inactive markets; inputs other than quoted prices that are observable for the asset or liability; inputs that are derived principally from or corroborated by observable market data by correlation or other means. If the asset or liability has a specified (contractual) term, the Level 2 input must be observable for substantially the full term of the asset or liability.

Level 3		Inputs to the valuation methodology are unobservable and significant to the fair value measurement.

FOR THE YEARS ENDED DECEMBER 31, 2012 AND 2011

NOTE 4 - FAIR VALUE MEASUREMENTS (CONTINUED)

The asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used need to maximize the use of relevant observable inputs and minimize the use of unobservable inputs.

Following is a description of the valuation methodologies used for assets measured at fair value. There have been no changes in these methodologies used at December 31, 2012 and 2011.

Certificates of deposit: Certificates of deposit are measured at amortized cost, which approximates fair value.

Collective funds, equity securities, mutual funds and short-term investments: The securities measured at fair value in Level 1 are based on quoted market prices in an exchange market. The securities measured at fair value in Level 2 are based on independent unadjusted market-based prices received from a third-party pricing service that utilizes pricing models that consider standard input factors such as observable market data, benchmark yields, interest rate volatilities, broker/dealer quotes, credit spreads and new issue data.

Hedge funds: The securities measured at fair value in Level 3 are valued based on management estimates as observable market data is not readily available. The Funds are valued at net asset value, as calculated by the Fund’s manager based upon the terms and conditions of the organizational documents of the underlying funds, with further consideration to portfolio risks.

NOTE 4 - FAIR VALUE MEASUREMENTS (CONTINUED)

(c)

The investment seeks to replicate as closely as possible, before expenses, the performance of the Standard & Poor 500 Index. Under normal market conditions, the fund will not invest less than 80% of its total assets in stocks in the index. It attempts to replicate the investment performance of the S&P 500 Index and generally intends to invest, via the Portfolio, in all 500 stocks comprising the S&P 500 in approximate proportion to their weightings in the index. The fund may sell securities that are represented in the index, or purchase securities that are not yet represented in the index, in anticipation of their removal from or addition to the index.

(d)	The objective of this fund is to maximize total return from income and capital growth. The Fund invests at least 90% of its asset in a portfolio of international sovereign, government, agency, corporate, bank and asset backed debt and debt-related securities and in derivatives.

(e)

This is an index fund that seeks to match the performance of the Barclays Capital Aggregate Bond Index by investing in a diversified sample of the bonds that make up the index. The index is the broadest measure of the US investment-grade bond market and is comprised of US Treasury and federal agency bonds, corporate bonds, residential and commercial mortgage-backed securities and asset-backed securities.

(f)

The objective of the Portfolio is to seek long-term total return by investing primarily in Sterling denominated fixed income debt securities. The investment approach combines a base of Sterling fixed income strategies with an overlay of global best ideas from the global fixed income and currency markets.

(g)	BlackRock Municipal Target Term Trust is a non-diversified, closed-end management investment company incorporated in the USA. The Fund’s objective is to manage a portfolio of municipal debt securities, while providing current income exempt from regular Federal income tax.

(h)

This Fund’s investment objective is capital appreciation. The Fund seeks to achieve its investment objective with low volatility relative to the equity markets. The Fund expects to have low correlation to traditional market indices. Each Trust aims to outperform the UBS Australia Bank Bill Index by 8% per annum over a full market cycle with a standard deviation of returns of 5% per annum.

(i)	The Fund’s objective is to provide long-term capital growth. The Fund invests in equity securities primarily of foreign issuers. The holdings are composed of, but not limited to, countries in Europe, Australia, and the Far East.

The Fund’s objective is to seek above-average rates of return and long-term capital growth through an investment in EnTrust Capital Diversified Fund QP Ltd., a fund of funds with a diversified portfolio of private investment entities and/or separately managed accounts managed by investment managers. The fair values of the investments in this category have been estimated using the net asset value per share of the investments. Investments in this category have exceeded the redemption restriction in effect for the first 12 months after acquisition. Shareholder redemptions are limited to shares having a value of up to a maximum of 50% of the net asset value of their shares as of the close of any quarter.

(b)

This category includes investments in hedge funds that pursue multiple strategies to diversify risks and reduce volatility. The Fund’s objective is to achieve superior risk-adjusted capital appreciation over the long term, generally through an investment in Crestline Offshore Fund, Ltd., which in turn invests in private investment funds and discretionary managed accounts, structured notes, swaps, or other similar products. The fair values of the investments in this category have been estimated using the net asset value per share of the investments. The investments in this category have exceeded the redemption restriction in effect after initial acquisition.

NOTE 5 - PLAN TERMINATION

Although it has not expressed any intent to do so, the Bank has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of Plan termination, participants will become 100% vested in their accounts.

NOTE 5 - PLAN TERMINATION (CONTINUED)

Any unallocated assets of the Plan shall be allocated to participant accounts and distributed in such a manner as the Bank may determine.

NOTE 6 - TAX STATUS

The Savings Banks Employees Retirement Association (SBERA) 401(k) Plan is a Prototype Plan. SBERA maintains the overall prototype plan document (master document). As of February 14, 2002, a favorable opinion letter has been received for all 401(k) plans. The Plan’s administrator and the Plan’s tax counsel believe that the Plan is designed and is currently being operated in compliance with the applicable requirements of the Internal Revenue Code. Therefore, no provision for income taxes has been included in the Plan’s financial statements.

Accounting principles generally accepted in the United States of America, require the Plan’s management to evaluate tax positions taken by the Plan and recognize a tax liability (or asset) if the Plan has taken an uncertain position that more likely than not would not be sustained upon examination by federal and state taxing authorities. The Plan administrator has analyzed the tax positions taken by the Plan, and has concluded that as of December 31, 2012 and 2011, there are no uncertain positions taken or expected to be taken that would require recognition of a liability (or asset) or disclosure in the financial statements. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress. The Plan Administrator believes it is no longer subject to income tax examinations for years prior to 2009.

NOTE 7 - RISKS AND UNCERTAINTIES

The Plan invests in various investment securities. Investment securities are exposed to various risks such as interest rate, market, and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect participants’ account balances and the amounts reported in the statements of net assets available for benefits.

NOTE 8 - RELATED-PARTY AND PARTY-IN-INTEREST TRANSACTIONS

connection with the administration of the 401(k) plan for the Savings Banks Employees Retirement Association (SBERA). The costs associated with these services are funded by an assessment on each SBERA employer member on a quarterly basis for their proportionate share. In 2012 and 2011, the rate for the 401(k) plan was $679.50 per employer member per quarter, plus $21.50 per active participant per quarter, plus an additional 1.25% basis assessment on assets.

The Plan invests in a common collective trust managed by SBERA, the Trustee of the Plan. Therefore, this qualifies as a party-in-interest transaction. Additionally, the Plan extends loans to participants, who are considered parties-in-interest.
