during a specified period preceding the Merger, plus cash in lieu of any
fractional share interest, subject to election and allocation procedures set
forth in the Agreement which are intended to ensure that 50% of the outstanding
shares of Warren common stock will be converted into the right to receive
Banknorth common stock and 50% of the outstanding shares of Warren common stock
will be converted into the right to receive cash.

         Consummation of the Merger is subject to a number of customary
