         On, November 21, 2005, the Company issued a press release announcing
that it has signed a definitive agreement to acquire AM&M Financial Services,

outstanding shares of AM&M capital stock for an amount paid in cash and Tompkins
common stock. The transaction is structured with a portion of the purchase price
payable at closing, with additional contingent amounts payable, depending on the
operation results of AM&M, during the four years after closing. It is currently
anticipated that the acquisition, which is subject to regulatory approval and
other customary conditions to closing, will be completed in the first quarter of
2006. A copy of the press release is attached to this Report on Form 8-K as
