                    BANKNORTH GROUP TO ACQUIRE WARREN BANCORP
                      VALUES TRANSACTION AT $122.6 MILLION

Portland, Maine, August 8, 2002 - Banknorth Group, Inc. (NASDAQ: BKNG),
announced today that it has signed a definitive agreement to acquire Warren
Bancorp, Inc. (NASDAQ: WRNB), parent company of Warren Five Cents Savings Bank,
for an estimated $122.6 million in cash and stock. The transaction will provide
Banknorth the leading market share in Essex County, Massachusetts with nearly a
16% deposit market share in the affluent North Shore county.

At June 30, 2002, Warren Bancorp had total assets of $460 million, total
deposits of $394 million, total loans of $345 million and shareholders' equity
of $44 million. Warren Five Cents Savings Bank operates six banking offices
exclusively in Massachusetts, four in Peabody and one each in Beverly and North
Beverly.

"We continue to execute our plan of acquiring sound banking companies that
extend and enhance our Massachusetts franchise," said William J. Ryan, Banknorth
Chairman, President and Chief Executive Officer. "The Warren market adds to our
already strong franchise in the Boston suburbs and brings to us a banking
tradition with deep roots in the communities it serves."

"Banknorth and Warren Bank are a great fit for North Shore customers who want
community banking to continue. Banknorth, though much larger than Warren, shares
our commitment to the communities it serves," said Stephen G. Kasnet, Chairman
of Warren Bancorp. "We believe that our shareholders will be excited by this
transaction and that our customers will benefit from Banknorth's extensive
branch network and its long list of products and services."

Banknorth Group, headquartered in Portland, Maine, operates in Massachusetts as
Banknorth Massachusetts. In the past year, Banknorth has previously acquired
Andover Bancorp, MetroWest Bank and Ipswich Bancshares.

The terms of the agreement call for outstanding shares of Warren common stock to
be converted into the right to receive $15.75 per share or a number of whole
shares of Banknorth determined by dividing $15.75 by the average closing prices
of the Banknorth common stock over a specified period, plus cash in lieu of any
fractional share interest.

The terms are subject to election and allocation procedures which are intended
to ensure that 50% of the outstanding Warren common stock will be converted into
the right to receive Banknorth common stock and 50% of the outstanding Warren
common stock will be converted into the right to receive cash. The transaction
is intended to qualify as reorganization for federal income tax purposes. As a
result, the shares of Warren stock exchanged for Banknorth stock will be
transferred on a tax-free basis.

The transaction is valued by Banknorth at 263% of Warren book value per share
at March 31, 2002 and 17.1 times consensus estimated earnings per share of
Warren for 2003.

The transaction is expected to be accretive by one cent per diluted share to
Banknorth earnings in 2003. Transaction costs of $6.2 million are anticipated.

The definitive agreement has been approved by the Board of Directors of
Banknorth and the Board of Directors of Warren. The transaction is subject to
all required regulatory approvals, the approval by shareholders of Warren and
other customary conditions. The transaction is expected to be completed by the
end of the year with operational integration to follow soon after.

Banknorth Group, Inc. is one of the country's 35 largest commercial banking
companies with total assets of $21.3 billion at June 30, 2002. The Company's
banking subsidiary, Banknorth, NA, operates banking divisions in Connecticut,
