   Brookline Bancorp Announces 2004 Third Quarter Operating Results
              and Quarterly Dividend of $0.085 Per Share

    BROOKLINE, Mass.--(BUSINESS WIRE)--Oct. 21, 2004--Brookline
Bancorp, Inc. (the "Company") (NASDAQ:BRKL) announced today its
earnings for the 2004 third quarter and approval by its Board of
Directors of a regular quarterly dividend of $0.085 per share payable
November 15, 2004 to stockholders of record on October 29, 2004.
    The Company earned $4,497,000, or $0.08 per share on a basic and
diluted basis, for the three months ended September 30, 2004 compared
to $4,502,000, or $0.08 per share on a basic and diluted basis, for
the three months ended September 30, 2003. Net income for the nine
months ended September 30, 2004 was $13,771,000, or $0.24 per share on
a basic and diluted basis, compared to $11,041,000, or $0.19 per share
on a basic and diluted basis, for the nine months ended September 30,
2003. The 2003 nine month period included an after-tax charge of
$2,788,000, or $0.05 per share, resulting from settlement of all
disputes relating to the state tax treatment of the Company's real
estate investment trust ("REIT") subsidiary for the years 1999 through
2002.
    The average balance of interest-earning assets increased $191
million, or 13.4%, in the 2004 third quarter compared to the 2003
third quarter and $64 million, or 4.1%, since the 2004 second quarter.
All of the increase from the prior year quarter and the immediately
preceding quarter came from the indirect automobile loan portfolio
which grew by $212 million and $64 million, respectively, during those
periods. Total indirect automobile loans outstanding were $345 million
at September 30, 2004.
    Despite the 13.4% rate of asset growth, net interest income
increased by only 4.50% between the 2004 and 2003 quarterly periods
due to a decline in interest rate spread from 2.41% to 2.28% in the
respective periods. The decline was attributable primarily to the
payment and maturity of higher yielding loans and investments and the
replacement of such assets with new loans and investments with lower
yields.
    We have previously reported that the interest rate environment of
the past two years has been the lowest in over forty years. As a
result, asset yields have declined steadily. Since a high percent of
the Company's assets (36% in the 2004 third quarter) are funded by
stockholders' equity for which there is no charge for interest
expense, declining rates cause a greater reduction in interest income
from lower asset yields than the reduction in interest expense from
lower rates paid on deposits and borrowed funds. From June to
September 2004, the Federal Reserve increased the federal funds rate
for overnight borrowings between banks from 1.00% to 1.75%. While this
rise in rates will likely have a positive impact on the Company's
future net interest income, earnings improvement will continue to be
restrained as long as existing assets are replaced with new assets at
lower yields.
    In anticipation of a rising interest rate environment, the Company
has restricted its purchase of investments over the past year to
securities with maturities of two years or less and has funded part of
its loan growth with borrowings at fixed rates and maturities in the
two to three year range. These actions have slowed down short-term
earnings improvement, but should enhance longer-term earnings if
interest rates continue to rise. Trends in interest rates depend on
many factors and, accordingly, actual rates in the future could vary
significantly with the Company's rate predictions. At September 30,
2004, interest-earning assets maturing or repricing within one year
amounted to $719.9 million and interest-bearing liabilities maturing
or repricing within one year amounted to $518.2 million, resulting in
a cumulative one year positive gap position of $201.7 million, or
12.3% of total assets.
    Interest yields have continued to be affected by prepayment of
certain investments and loans. Some of the investment securities
purchased by the Company in 2002 and the first four months of 2003 are
secured by mortgage loans. Prepayment of some of the mortgage loans
underlying the securities purchased shortened their estimated life and
resulted in the accelerated expensing of part of the premiums paid to
purchase the securities. Accelerated premium amortization related to
such securities in the 2004 and 2003 nine month periods was $250,000
and $1,806,000, respectively. Mortgage loan payoffs generated
prepayment fees of $1,364,000 in the 2004 nine month period compared
to $762,000 in the 2003 nine month period. Prepayments also occurred
in 2004 in the indirect automobile loan portfolio. Upon a loan
prepayment, the remainder of unamortized costs incurred in originating
the loan must be expensed as a charge to interest income. Such charges
amounted to $356,000 in the 2004 third quarter and $1,018,000 in the
2004 nine month period. Charges in the 2003 periods were
insignificant.
    The provision for loan losses increased from $240,000 in the 2003
third quarter to $635,000 in the 2004 third quarter and from $975,000
in the 2003 nine month period to $1,676,000 in the 2004 nine month
period. The increases were due primarily to growth of the indirect
automobile loan portfolio. Non-performing assets, comprised of loans
past due 90 days or more and repossessed assets, were insignificant
($336,000) at September 30, 2004. The allowance for loan losses was
$17,161,000, or 1.38% of total loans outstanding, at that date.
    Securities gains were $806,000 and none, respectively, in the 2004
and 2003 third quarters and $1,767,000 and $508,000, respectively, in
the 2004 and 2003 nine month periods. The gains resulted from sales of
marketable equity securities.
    The expense for restricted stock awarded under the Company's
recognition and retention plan amounted to $722,000 and $40,000,
respectively, in the 2004 and 2003 third quarters and $2,168,000 and
$106,000, respectively, in the 2004 and 2003 nine month periods. The
increases resulted from awards made under the plan approved by
stockholders in October 2003. Other non-interest expense increased
$249,000, or 5.1%, in the 2004 third quarter compared to the 2003
third quarter and $1,542,000, or 11.4%, in the 2004 nine month period
compared to the 2003 nine month period. Such increases were due
primarily to operation of the indirect automobile loan business which
commenced in February 2003, the opening of a new branch in the fall of
2003 and the payment of dividend equivalent rights of $734,000 in the
2004 nine month period compared to $361,000 in the 2003 nine month
period.
