ITEM 5.                    OTHER EVENTS.

         Cargill Bank ("Cargill"), a wholly owned subsidiary of Westbank
Corporation ("Westbank"), has entered into an agreement with PM Holdings, Inc.,
("PM Holdings") a wholly owned subsidiary of Phoenix Home Life Mutual Insurance
Company ("Phoenix") and PM Trust Holding Company, a wholly owned subsidiary of
PM Holdings to purchase the Connecticut banking division of New London Trust,
FSB. The sale will occur immediately after PM Trust's acquisition of all the
outstanding capital stock of New London Trust from Sun Life Assurance Company of
Canada (U.S.). New London Trust is a $325 million federal savings bank which
also operates a trust division with assets of $1 billion. New London Trust has
five New Hampshire branches in New London, Hanover, Andover and Newbury; trust
offices in New London, Hanover and Peterborough, NH; and two Connecticut
branches in Danielson and Putnam.

         Following the acquisition of New London Trust by PM Trust, PM Trust
will retain the trust business and the three trust offices. Immediately
following the transaction, PM Trust will sell the assets, liabilities and the
banking offices of New London Trust's New Hampshire banking operations to Lake
Sunapee Bank, fsb and Mascoma Savings Bank and the Connecticut banking
operations to Cargill.

         Westbank will acquire the two branches of New London Trust in Danielson
and Putnam, Connecticut with assets totaling $110 million to add to its recently
acquired Cargill Bank subsidiary. Upon completion, the New London Trust offices
in Danielson and Putnam, Connecticut will become branch offices of Cargill Bank,
which will operate five banking offices with a total of $165 million in assets.
The combined assets of Westbank upon completion of the acquisition of the two
Connecticut branch offices will be in excess of $525 million.

         Cargill's purchase of the Connecticut branches is subject to regulatory
approval and is expected to be completed in the fourth quarter of 1999. The
acquisition agreement was publicly announced in a press release dated April 12,
1999, a copy of which is attached hereto as Exhibit 99.1.
