nine months of this year." As of September 30, 2003, loan originations totaled
$178,000,000. During the same period, the Corporation has securitized
$26,000,000 in residential real estate loans and sold another $22,000,000 of
residential real estate loans in the secondary market.

We are pleased to announce that our new Webster, Massachusetts, office opened on

October. "We anticipate this new office to be a very productive addition to our
branch system," according to Chase.

Chase also announced the completion of Westbank's most recent stock repurchase
plan and said, "The Corporation will initiate a new repurchase plan of 5% of the
Corporation's stock." Chase commented, "The repurchase plan is being continued
because the Board of Directors believes it is a wise and valuable long-term
investment. The repurchase plan will add to shareholder value through improved
earnings per share and by providing an additional source of liquidity." Based on
the current stock price, the repurchase plan is valued at approximately $3.8
million.
