WESTBANK CORPORATION REPORTS

West Springfield, MA -- Westbank Corporation (Nasdaq: WBKC) today reported net

According to Chase, "Commercial loan activity continues to drive our loan
volume, with commercial mortgages totaling $141 million at March 31, 2006 versus
$118 million at March 31, 2005, an increase of $23 million or 19%. In addition,
we are pleased to see a slight increase in residential mortgage activity."

"We are also pleased to report that construction of our newest full-service
branch office in Southwick, Massachusetts, is moving along nicely," Chase
continued. "This new office will be a 3,000-square-foot facility with two
drive-up windows and a drive-up ATM. The office will replace our much smaller
Southwick office and will be located at 664 College Highway in the town of
Southwick. We expect the office to open for business during June of this year."

Chase also commented that, "April marks the one-year anniversary of our
affiliation with Infinex Financial Services. The Financial Services division
(Westco Financial Services) offers investment and insurance services. We begin
our second year of operation with assets under management of approximately $10
million and we look forward to continued growth in this business line during the
