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 the fall of this year."

Chase also commented that, "The Corporation has recently formed an alliance with
Infinex Financial Services. The financial services division will offer
investment and insurance services to customers and will be an excellent
compliment to our Trust Department's `Wealth Management' Division. The
Corporation will employ two financial services representatives as part of this
new line of business."
