Information Concerning Forward-Looking Statements.


Westbank has made and may make in the future forward-looking statements
concerning future performance, including, but not limited to, future earnings,
and events or conditions which may affect such future performance. These
forward-looking statements are based upon management's expectations and belief
concerning possible future developments and the potential effect of such future
developments on Westbank. There is no assurance that such future developments
will be in accordance with management's expectations and belief or that the
effect of any future developments on Westbank will be those anticipated by
Westbank management.

All assumptions that form the basis of any forward-looking statements regarding
future performance, as well as events or conditions which may affect such future
performance, are based on factors that are beyond Westbank's ability to control
or predict with precision, including future market conditions and the behavior
of other market participants. Among the factors that could cause actual results
to differ materially from such forward-looking statements are the following:

         1.   The status of the economy in general, as well as in Westbank's
               primary market area, Western Massachusetts;

         2.   The real estate market in Western Massachusetts;

         3.   Competition in Westbank's primary market area from other banks,
               especially in light of continued consolidation in the New England
               banking industry.

4.       Any changes in federal and state bank regulatory requirements;

         5.       Changes in interest rates; and

         6.       The cost and other effects of unanticipated legal and
                  administrative cases and proceedings, settlements and
                  investigations.

The assumptions listed above, as they relate to Cargill Bank, are the same with
the exception of the market area, which is Northeast Connecticut.

While Westbank periodically reassesses material trends and uncertainties
affecting the Corporation's performance in connection with is preparation of
management's discussion and analysis of results of operations and financial
condition contained in its quarterly and annual reports, Westbank does not
intend to review or revise any particular forward-looking statement in light of
future events.
