Item 8.01   Other Events

      On November 27, 2007, Camden National Corporation ("Camden") issued a
press release announcing that its Board of Directors has authorized Camden to
seek approval to transfer the listing of its shares of common stock from the
American Stock Exchange ("AMEX") to the NASDAQ Global Select Market ("NASDAQ").
Upon transfer, Camden expects to retain the trading symbol "CAC." Camden
anticipates that such transfer, if approved by NASDAQ, will be effective on or
about January 1, 2008.

      Under the terms of the Agreement and Plan of Merger between Camden and
Union Bankshares, dated as of August 13, 2007, as amended, pursuant to which
Union Bankshares will merge with and into Camden (the "Merger"), Camden agreed
to use its reasonable best efforts to obtain approval for listing on AMEX the
shares of Camden common stock to be issued to Union Bankshares shareholders in
the merger. In addition, one of the closing conditions to the Merger is that the
shares of Camden stock to be issued to Union Bankshares shareholders shall have
been approved for listing on AMEX. In the event that Camden common stock is
traded on NASDAQ rather than AMEX at the closing of the Merger, Camden will seek
a waiver under the Merger Agreement from these requirements. In return, Camden
will agree to use its reasonable best efforts to obtain approval for listing on
NASDAQ the shares of Camden common stock to be issued to Union Bankshares
shareholders in the Merger, and will agree that, as a closing condition to the
Merger, the shares of Camden stock to be issued to Union Bankshares shareholders
shall have been approved for listing on NASDAQ. Union Bankshares has informed
Camden that it will grant this waiver if so requested.
