Portland, Maine, June 11, 2001 - Banknorth Group, Inc. (NASDAQ: BKNG), announced
today that it has signed separate definitive agreements to acquire both Andover
Bancorp, Inc. ("Andover") (NASDAQ: ANDB) for approximately $333 million in
stock, and MetroWest Bank ("MetroWest") (NASDAQ: MWBX) for approximately $166
million in cash. The acquisitions will increase the Company's total assets from
just over $18 billion to approximately $21 billion and expand its Massachusetts
banking franchise to 114 branches and nearly $9 billion in assets.

At March 31, 2001 Andover had total assets of $1.8 billion, deposits of $1.3
billion and shareholders' equity of $160 million, and serviced its customer base
from 15 branch locations covering Essex and Middlesex counties in Massachusetts
and Rockingham County in New Hampshire. At the same date, MetroWest had total
assets of $914 million, deposits of $705 million and shareholders' equity of $63
million, and served Middlesex, Norfolk, Suffolk, and Worcester counties in
Massachusetts through 17 branch locations.

"These acquisitions are a natural extension of our Massachusetts banking
franchise, and significantly enhance our presence in the economically vibrant
communities of Greater Boston," said William J. Ryan, Chairman, President and
Chief Executive Officer of Banknorth. "Both Andover and MetroWest customers will
benefit from having greater convenience through our extensive network of
branches and ATMs and will enjoy a broader selection of products and services."

Gerald T. Mulligan, Andover's President, said the enhanced product offerings
include trust and investments services, cash management and government banking
services.

"Banknorth is an ideal acquirer for Andover," said Mr. Mulligan. "Banknorth
shares Andover's commitment to customer service and lending to the local
community."

John J. McArdle III, Chief Executive Officer of MetroWest Bank, similarly noted
that its customers would benefit from expanded services.

"It was important to us that any acquirer share our commitment to community
banking and be in a position to enhance our ability to meet our customers'
needs," said Mr. McArdle. "Our customers will now also be served by a much
larger banking franchise with branches in many surrounding communities."

Under the terms of the agreement to acquire Andover, shareholders will receive a
fixed exchange ratio of 2.27 shares of Banknorth common stock for each share of
Andover they hold plus cash in lieu of any fractional share interest. Based on
Banknorth's closing price on June 8, 2001 of $21.19 per share, this would equal
$48.10 a share. The exchange will be tax free and accounted for as a purchase
transaction.

The MetroWest agreement calls for shareholders of MetroWest to receive $11.50 in
cash for each share they hold.

Both agreements were approved by the Board of Directors of Banknorth and by the
Board of Directors of Andover and MetroWest, respectively. The transactions are
expected to be completed by year-end, and are subject to regulatory approval and
approval by the respective shareholders of Andover and MetroWest. It is expected
that the operational integration of the institutions will be completed during
the first quarter of 2002.

In connection with these transactions, Andover and MetroWest each granted to
Banknorth an option to purchase 19.9 percent of its outstanding common stock
under certain conditions.

Andover's Massachusetts franchise (including Gloucester Bank and Trust Company),
and MetroWest's branches will be merged into Banknorth's existing Massachusetts
bank, First Massachusetts Bank, N.A., resulting in a subsidiary bank with 114
branches, $5.5 billion in deposits and nearly $9 billion in assets. Andover also
operates three branches in Rockingham County, New Hampshire, where Banknorth
already enjoys the leading deposit market share with First Massachusetts
branches and branches of its New Hampshire subsidiary, Bank of New Hampshire,
N.A.

The addition of Andover and MetroWest to Banknorth's Massachusetts franchise
will move Banknorth into the No. 5 market share position in the Boston
metropolitan statistical area, the fourth most populous MSA in the country. In
addition, the acquisitions will give Banknorth the No. 2 deposit market share in
Essex County (currently No. 7), with an average household income of $67,906, and
the No. 7 deposit market share in Middlesex County (currently No. 19), with an
average household income of $82,492, as well as enhancing Banknorth's existing
No. 3 market share position in Worcester County, with an average household
income of $58,198.

"We gain significant market share in important Massachusetts markets," said Mr.
Ryan. "We are becoming an important force in banking and financial services in
Massachusetts, which complements our leading market position in Maine and New
Hampshire and number two market position in Vermont."

Banknorth Group, Inc., headquartered in Portland, Maine, is the country's 36th
largest commercial banking company by assets with total assets of $18.3 billion
at March 31, 2001. The Company operates banking subsidiaries in Maine, Peoples

geographic presence in the western area of metropolitan Boston and to signify
its transition to commercial banking. MetroWest has branches in Middlesex,
