         This report contains statements that may be considered forward-looking
statements within the meaning of Section 27A of the Securities Act of 1933 and
Section 21E of the Securities Exchange Act of 1934. Forward-looking statements
can be identified by the use of the words "believe," "expect," "anticipate,"
"intend," "estimate," "assume," "will," "should," and other expressions which
predict or indicate future events or trends and which do not relate to
historical matters. Forward-looking statements should not be relied on, because
they involve known and unknown risks, uncertainties and other factors, some of

achievements of Camden and Union Bankshares to be materially different from the
anticipated future results, performance or achievements expressed or implied by

         Some of the factors that might cause these differences include the
following: (i) failure of the parties to satisfy the closing conditions in the
Merger Agreement in a timely manner or at all; (ii) failure of the shareholders
of Union Bankshares to approve the Merger Agreement; (iii) failure to obtain
governmental approvals of the Merger, or imposition of adverse regulatory
conditions in connection with such approvals; (iv) disruptions in the businesses
of the parties as a result of the pendency of the Merger; (v) integration costs
following the merger, (vi) changes in general, national or regional economic
conditions; (vii) changes in loan default and charge-off rates; (viii)
reductions in deposit levels necessitating increased borrowing to fund loans and
investments; (ix) changes in interest rates; (x) changes in laws and
regulations; (xi) changes in the size and nature of the Camden's competition and
(xiii) changes in the assumptions used in making such forward-looking
statements. Other factors could also cause these differences. For more

 Union Bankshares Company Shareholders Overwhelmingly Approve Merger
                   with Camden National Corporation


    CAMDEN, Maine & ELLSWORTH, Maine--(BUSINESS WIRE)--Nov. 29,
2007--Camden National Corporation (AMEX: CAC) and Union Bankshares
Company (OTCBB: UNBH.OB) announced today that the shareholders of
Union Bankshares voted to approve the previously announced merger
between Camden and Union Bankshares at Union Bankshares' special
meeting of shareholders on November 29, 2007. 74.75% of shareholders
voted in favor of the merger while 1.36% voted against. The remaining
23.89% of the votes abstained.

    The proposed merger is expected to close in January, 2008.
Completion of the acquisition is subject to customary closing
conditions and approval by various regulatory agencies.

    Change in Election Deadline

    The companies also announced that due to the holidays, the
deadline for merger consideration elections, which was previously
announced as December 20, 2007, has been extended to December 26,
2007. Materials regarding merger consideration elections were mailed
to Union Bankshares shareholders beginning on November 19, 2007.

    Union Bankshares shareholders wishing to make an election
regarding the consideration they would like to receive for their Union
Bankshares shares must deliver to Computershare Trust Co., Inc., the
exchange agent, properly completed Election Forms and Letters of
Transmittal, together with their stock certificates, or properly
completed notices of guaranteed delivery, by 5:00 P.M., New York City
time, on Wednesday, December 26, 2007, the newly extended election
deadline. Union Bankshares shareholders may elect cash, shares of
Camden common stock or a combination of the two for their Union
Bankshares shares. All elections are subject to adjustment to ensure
that 60% of the outstanding shares of Union Bankshares common stock
will be converted into the right to receive shares of Camden common
stock, and the remaining shares of Union Bankshares common stock will
be converted into the right to receive cash. As a result, a Union
Bankshares shareholder may not receive the exact form of consideration
elected, and the ability of a Union Bankshares shareholder to receive
the form of consideration elected will depend on the elections made by
other Union Bankshares shareholders.

    Union Bankshares shareholders who do not properly deliver such
documentation to Computershare Trust Co., Inc. at the address
specified in the Election Form and Letter of Transmittal prior to the
election deadline will forfeit the right to select the form of
consideration they would like to receive. If the acquisition is
completed, such non-electing shareholders will be allocated Camden
common stock and/or cash depending on the elections made by other
Union Bankshares shareholders.

    Union Bankshares shareholders may obtain additional copies of the
Election Form and Letter of Transmittal by contacting Georgeson Inc.,
the information agent, at 1-888-651-3212.

    This communication shall not constitute an offer to sell or the
solicitation of an offer to sell or the solicitation of an offer to
buy any securities.
