Exhibit 99.1

   Brookline Bancorp Announces 2004 Second Quarter Operating Results
       and Declaration of Per Share Regular Dividend of $0.085
                     and Extra Dividend of $0.20

    BROOKLINE, Mass.--(BUSINESS WIRE)--July 15, 2004--Brookline
Bancorp, Inc. (the "Company") (NASDAQ:BRKL) announced today its
earnings for the 2004 second quarter 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 on August 16, 2004 to
stockholders of record on July 30, 2004.
    The Company earned $4,622,000, or $0.08 per share on a basic and
diluted basis, in the 2004 second quarter compared to $6,687,000, or
$0.12 per share on a basic and diluted basis, in the 2003 second
quarter. The 2003 quarter included an after-tax credit of $2,727,000,
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.
    Net income for the six months ended June 30, 2004 was $9,274,000,
or $0.16 per share on a basic and diluted basis, compared to
$6,539,000, or $0.11 per share on a basic and diluted basis, for the
six months ended June 30, 2003. The 2003 period included an after-tax
net charge to earnings of $2,788,000, or $0.05 per share, resulting
from settlement of the REIT tax matter. The credit mentioned in the
preceding paragraph is the difference between the liability recorded
in the first quarter of 2003 and the amount of the settlement paid in
the 2003 second quarter, net of related tax benefits.
    Excluding the credit resulting from the REIT tax matter, net
income in the 2004 second quarter was $662,000, or 16.7%, higher than
in the 2003 second quarter. The increase was attributable to
improvement in net interest income ($1,265,000 after taxes), offset in
part by a higher provision for loan losses ($204 after taxes) and the
expense of restricted stock awards ($396,000 after taxes).
    The 20.3% increase in net interest income from $10,712,000 in the
2003 second quarter to $12,887,000 in the 2004 second quarter resulted
from a $166 million, or 11.8%, growth in interest-earning assets and
an increase in the average rate earned on those assets from 4.38% to
4.55%. Asset growth came from the indirect automobile loan portfolio
which increased by $247 million in average balances outstanding
between the two quarterly periods. Total indirect automobile loans
outstanding were $313 million at June 30, 2004. Offsetting part of
this growth was a $92 million reduction in average balances invested
in debt securities and short-term investments. This shift in the mix
of earning assets was part of the reason for the improvement in the
average rate earned, as yields on loans generally exceed yields on
investments.
    As we have reported in previous quarterly communications, 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 (38% in the 2004 second
quarter) were funded by stockholders' equity for which there is no
charge for interest expense, declining rates caused 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. On June 30, 2004, the Federal Reserve increased the
federal funds rate for overnight borrowings between banks for the
first time since May 16, 2000 from 1.00% to 1.25%. From May 2000
through June 2004, the federal funds rate had declined from 6.50% to
1.00%; it remained at 1.00% since June 25, 2003. While rising interest
rates would likely have a positive impact on the Company's net
interest income and net interest margin, future trends in interest
rates are dependent on many factors.
    In a declining low interest rate environment, not only are new
loans originated and investments purchased at lower yields, but
existing higher yielding loans and investments secured by mortgage
loans are subject to prepayment before scheduled maturities.
Prepayment of higher yielding assets in a declining interest rate
environment can have a detrimental effect on net interest income. The
Company experienced such an effect during the past two years.
Unprecedented prepayment of loans underlying mortgage securities in
which the Company had invested shortened the estimated life of the
securities significantly, thus necessitating the accelerated expensing
of part of the premiums paid to purchase the securities. Accelerated
premium amortization caused by loan prepayments was $1,680,000 in the
2003 second quarter and $357,000 in the 2004 first quarter. In the
2004 second quarter, $232,000 was credited to income as subsiding
prepayments extended the estimated remaining life of the securities.
    Mortgage loan payoffs generated prepayment fee income of
$1,141,000 in the first half of 2004 ($278,000 in the second quarter)
and $517,000 in the first half of 2003 ($339,000 in the second
quarter). Prepayments also occurred in 2004 in the indirect automobile
loan portfolio due in part to aggressive loan promotions by credit
unions, banks and credit card issuers. When prepayments arise, the
remainder of unamortized costs incurred in originating the loans must
be expensed as a charge to interest income. Such charges amounted to
$321,000 in the 2004 second quarter and $649,000 in the first half of
2004.
    The provision for loan losses increased from $360,000 in the 2003
second quarter to $711,000 in the 2004 second quarter and from
$735,000 in the first half of 2003 to $1,041,000 in the first half of
2004 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 ($322,000) at June
30, 2004. The allowance for loan losses was $16,962,000, or 1.44% of
total loans outstanding, at that date.
    Securities gains were $381,000 and $181,000, respectively, in the
2004 and 2003 second quarters and $961,000 and $508,000, respectively,
in the first half of 2004 and 2003. The expense for restricted stock
awarded under the Company's 2003 recognition and retention plan
amounted to $681,000 in the 2004 second quarter and $1,371,000 in the
first half of 2004. Other non-interest expenses increased $284,000, or
6.2% in the 2004 second quarter compared to the 2003 second quarter
and $1,302,000, or 14.9%, in the first half of 2004 compared to the
first half of 2003 due primarily to operations related to the indirect
automobile loan business, the opening of a new branch in the fall of
2003 and $375,000 of dividend equivalent rights payments in the first
quarter of 2004.
    In approving an extra dividend of $0.20 per share in addition to
the regular quarterly dividend of $0.085 per share, the Board of
Directors considered a number of factors. The recent announcement to
acquire Mystic Financial Inc., which is expected to be completed in
January 2005, was not viewed to be of such a magnitude as to affect
extra dividend payments. While it is the intent of the Board for the
foreseeable future to authorize payment of an extra dividend
semi-annually, the payment and magnitude of any future extra dividend
will be considered in light of changing opportunities to deploy
capital effectively, including the repurchase of stock, future income
tax rates, expansion of the Company's business and general economic
conditions.

(1) Tax exempt income on equity securities is included on a tax
    equivalent basis.
(2) Average balances include unrealized gains on securities available
    for sale. Equity securities include marketable equity securities
    (preferred and common stocks) and restricted equity securities.
(3) Loans on non-accrual status are included in average balances.
(4) Included in interest income on debt securities in the 2004 period
    is $232 of income resulting from adjustment of the amortization of
    premiums on mortgage securities. Excluding this credit, the yield
    on debt securities in the 2004 period would have been 2.51%.
    Included in interest income in the 2003 period is $1,680 of
    accelerated amortization of premiums on mortgage securities.
    Excluding this charge, the yield on debt securities in the 2003
    period would have been 2.84%.
(5) Included in interest income on indirect automobile loans in the
    2004 period is $321 of accelerated amortization of deferred loan
    origination costs due to prepaid loan payoffs. Excluding this
    charge, the yield on the indirect automobile loan portfolio would
    have been 4.37% in the 2004 period.
(6) Excluding the adjustments on debt securities and indirect
    automobile loans noted above, the yield on interest-earning assets
    would have been 4.57% in the 2004 period and 4.85% in the 2003
    period.
(7) Included in interest expense in the 2004 period is $33 reduction
    of expense due to a rate adjustment. Excluding this adjustment,
    the cost of certificates of deposit in the 2004 period would have
    been 2.58% and the cost of interest-bearing liabilities would have
    been 2.15%.
