During the quarter and year ended December 31, 2005, the Corporation's provision

The allowance for loan losses totaled $4,199,000 or 0.97% of total loans at

At December 31, 2005, gross loans totaled $432,459,000, a decline of 2% or
$6,910,000. The decline is the result of the sale of approximately $47,400,000
in fixed-rate residential real estate loans during the year. The Corporation
completed this restructuring strategy in anticipation of higher interest rates.
Donald R. Chase, President and Chief Executive Officer, said, "We were
encouraged with our commercial real estate growth this past year, which
increased by approximately $17,900,000 or 15% over year-end 2004."

Stockholders' equity at December 31, 2005 was $47,378,000, representing a book
value of $9.97 per share. For the year ended December 31, 2005, the return on
average assets was 0.67%, while the return on average equity was 10.78%.

"The newly-formed Westco Financial Services Division continues to grow at a
steady pace and our Financial Services representatives now have approximately $8
million under management," according to Chase. The Financial Services Division
became active during June 2005.

Chase also said, "We anticipate announcing a new relationship account within the
next 30 days." The new account will reward customers with multiple account
relationships with better rate structures, as well as reduced fees and free
services for many of our banking products. Chase continued, "This should blend
well with our Overdraft Privilege product that was just introduced during
November."

Westbank Corporation is the parent company of Westbank, a West Springfield,
Massachusetts, commercial bank and trust company operating 17 banking offices in
Massachusetts and Connecticut, with $808 million of total assets at December 31,
