CENTURY BANCORP, INC. REPORTS FIRST QUARTER RESULTS

Medford, MA, April 23, 2007—Century Bancorp, Inc. (NASDAQ:CNBKA) (www.century-bank.com) (“the Company”) today announced net income of $1,004,000, or $0.18 per share diluted, for the first quarter ended March 31, 2007, compared to net income of $1,430,000, or $0.26 per share diluted, for the first quarter ended March 31, 2006. Included in income for 2006 is the previously announced pre-tax gain of $600,000 from the sale of its rights to future royalty payments for a portion of its Merchant Credit Card customer base.

Net interest income totaled $9,202,000 for the quarter ended March 31, 2007, versus $9,327,000 for the same period in 2006. The 1.3% decrease in net interest income for the period is mainly due to the current inverted yield curve environment and increased funding costs that resulted in a decrease of 3 basis points in the net interest margin.

At March 31, 2007, total equity was $108.9 million compared to $106.8 million at December 31, 2006. The Company’s equity was increased by an improvement of $1.6 million in the net unrealized loss on the Company’s available-for-sale portfolio as well as earnings less dividends paid. The Company’s leverage ratio stood at 8.81% on March 31, 2007, compared to 8.67% for the same period a year ago. Book value as of March 31, 2007 was $19.65 per share compared to $18.65 for the same period last year.

The Company’s allowance for loan losses was $9.8 million or 1.37% of loans outstanding at the end of the first quarter of 2007, compared to $9.7 million, or 1.32% of loans outstanding at December 31, 2006 and $9.4 million or 1.31% at March 31, 2006. Non-performing assets totaled $0.6 million at March 31, 2007, compared to $0.1 million at December 31, 2006 and $0.2 million at March 31, 2006.
