Brookline Bancorp Announces 2006 Fourth Quarter and Annual Earnings and Dividend
Declarations

     BROOKLINE, Mass.--(BUSINESS WIRE)--Jan. 18, 2007--Brookline Bancorp, Inc.
(the "Company") (NASDAQ:BRKL) announced today its earnings for the 2006 fourth
quarter and year and approval by its Board of Directors of a regular quarterly
dividend of $0.085 per share and an extra dividend of $0.20 per share payable
February 16, 2007 to stockholders of record on February 2, 2007.

     The Company earned $5,377,000, or $0.09 per share on a basic and diluted
basis, for the quarter ended December 31, 2006 compared to $5,536,000, or $0.09
per share on a basic and diluted basis, for the quarter ended December 31, 2005.
The 2005 quarter included a gain of $322,000 ($187,000 on an after-tax basis)
from the sale of a building and a foreclosed property. In the 2006 quarter, the
adverse consequences on operating results of an inverted yield curve environment
was softened by the additional earnings resulting from the purchase of a
controlling interest in Eastern Funding LLC ("Eastern") on April 13, 2006 and a
lower provision for loan losses.

     Net income for the year ended December 31, 2006 was $20,812,000, or $0.34
per share on a basic and diluted basis, compared to $22,030,000, or $0.37 per
share ($0.36 per share on a diluted basis), for the year ended December 31,
2005. Included in net income were after-tax securities gains of $358,000 in 2006
and $547,000 in 2005. Excluding securities gains, the $1,029,000, or 4.8%,
decline in net income was attributable to a $1,383,000 ($805,000 on an after-tax
basis) reduction in mortgage loan prepayment fees in 2006 compared to 2005 and
the adverse consequences of the inverted yield curve environment.

     Interest rate spread has been declining steadily from 2.59% in the 2005
first quarter to 2.33% in the 2005 fourth quarter and 2.06% in the 2006 fourth
quarter. The trend in net interest margin was similar to that in interest rate
spread, although less pronounced in the degree of decline. Net interest margin
declined from 3.31% in the 2005 first quarter to 3.19% in the 2005 fourth
quarter and 3.12% in the 2006 fourth quarter. Net interest margin was aided in
the last three quarters of 2006 by inclusion of the higher yielding Eastern loan
portfolio. Improvement in interest rate spread and net interest margin will
continue to be difficult to achieve until the slope in the yield curve commences
an upward movement.

     Interest income was 24% higher in the 2006 fourth quarter and year than in
the 2005 fourth quarter and year. Net interest income, however, increased only
5% and 3%, respectively, as interest expense rose 53% between the quarterly
periods and 60% between the years. The dramatic increase in interest expense
resulted from a rising interest rate environment triggered by rate setting
actions of the Federal Reserve, increased competition for deposits and a shift
in the mix of deposits. Customarily, higher rates are paid on certificates of
deposit than on transaction deposit accounts. Certificates of deposit comprised
61% of total retail deposits at December 31, 2006 compared to 55% at December
31, 2005 and 41% at December 31, 2004.

     As to asset yields, rates earned on mortgage loans generally are higher
than the rates earned on most of the Company's other interest-earning assets.
Over the past year, mortgage loan pricing has been subjected to increased
competitive pressure and, as a result, it has been increasingly difficult to
incorporate the rise in funding costs into the pricing of new loan originations.
Due in part to this development, the average balance of mortgage loans
outstanding was $28 million less in the 2006 fourth quarter than in the 2006
third quarter and $19 million less in the year 2006 than in the year 2005.

     Offsetting part of the decline in mortgage loan income was interest income
from the indirect automobile and Eastern loan portfolios. Indirect automobile
loans outstanding grew from $369 million at the end of 2004 to $459 million at
the end of 2005 and $540 million at the end of 2006. The average yield earned on
that portfolio grew from 4.30% in 2005 to 5.17% in 2006; the average yield in
the 2006 fourth quarter rose to 5.58%. Eastern loans outstanding at December 31,
2006 were $127 million and the average yield earned on the Eastern portfolio
since the acquisition in April 2006 was 10.83%. Eastern, which specializes in
the financing of coin-operated laundry, dry cleaning and grocery store equipment
in the greater metropolitan New York area and selected other locations in the
Northeast, is 86.7% owned by the Company.

     The provision for loan losses was $129,000 in the 2006 fourth quarter
compared to $840,000 in the 2005 fourth quarter and $2,549,000 in the year 2006
compared to $2,483,000 in the year 2005. The provision for loan losses is
comprised of amounts relating to the indirect automobile loan portfolio, the
Eastern loan portfolio and the remainder of the Company's loan portfolio.

     The provision for loan losses related to the indirect automobile loan
portfolio was $744,000 and $840,000, respectively, in the 2006 and 2005 quarters
and $3,098,000 and $2,859,000, respectively, in 2006 and 2005. These amounts
exceeded net charge-offs which amounted to $1,839,000 (0.35% of average loan
balances outstanding) in the year 2006 and $1,358,000 (0.32%) in the year 2005.
Loans delinquent 30 days or more were $7.1 million, or 1.31% of loans
outstanding at the end of 2006 compared to $5.9 million, or 1.28% of loans
outstanding at the end of 2005. The allowance for loan losses related to
indirect automobile loans increased from $2.9 million (0.64% of the portfolio)
at December 31, 2005 to $4.2 million (0.77% of the portfolio) at December 31,
2006.

     The provision for loan losses related to the Eastern portfolio was $435,000
in the 2006 fourth quarter and $851,000 since the acquisition. Net charge-offs
in those periods were $442,000 and $515,000, respectively. Loans delinquent 30
days and over were $1.4 million, or 1.13% of loans outstanding at December 31,
2006.

     Regarding the remainder of the Company's loan portfolio, a credit to the
provision for loan losses of $1,050,000 was taken to income in the 2006 fourth
quarter and credits of $1,400,000 and $375,000 were taken to income in the years
2006 and 2005, respectively. (There was no provision or credit to loan losses in
the 2005 fourth quarter). The credits resulted from reduction in outstanding
loans through pay down (including loans classified as higher credit risk loans)
and a reduction in the reserve factor applied to the multi-family mortgage loan
portfolio from 1.25% to 1.00%. That change, which was made after consideration
of a number of factors including loss experience, pay down of the portfolio and
current market conditions, resulted in an $828,000 reduction in the allocated
portion of the allowance for loan losses at December 31, 2006.

     At December 31, 2006, the Company transferred $1,286,000 out of the
allowance for loan losses to other liabilities to conform with generally
accepted accounting principles. The transfer had no effect on earnings. The
amount represents the allowance for estimated losses on unfunded loan
commitments.

     The decline in non-interest income from $5,297,000 in the year 2005 to
$3,850,000 in the year 2006 was due primarily to the decrease in gains from the
sales of assets mentioned earlier, less fees from prepayment of mortgage loans,
as well as lower earnings from Eastern before the Company's increase in
ownership.

     Non-interest expenses in the year 2005 included $894,000 of
merger/conversion expenses related to the acquisition of Mystic Financial, Inc.
Excluding those expenses, the increases in non-interest expenses in the 2006
quarterly and yearly periods compared to the 2005 quarterly and yearly periods
were due primarily to the inclusion of Eastern's expenses since the date of
acquisition, the expenses related to the opening of a new branch in April 2006,
the hiring of new loan officers, and higher processing and servicing costs
resulting from growth of the indirect automobile loan portfolio.

     The extra dividend of $0.20 per share to be paid on February 16, 2007 is
the eighth time since August 2003 that the Board of Directors has approved such
a payment. The aggregate amount paid, over $96 million or $1.60 per share,
represents a return of capital to stockholders (subject to taxation) rather than
a distribution of earnings. The payout of semi-annual extra dividends has been
an effective means of reducing the Company's excess capital in a measured way
and treating all stockholders equally. While it is the intent of the Board of
Directors to continue to return capital to stockholders through payment of an
extra dividend semi-annually, the magnitude of any future payment will be
considered in light of changing opportunities to deploy capital effectively,
including the repurchase of Company common stock and expansion of the Company's
business through acquisitions.
