Tri-Continental Announces Board Nominees Will Be Re-Elected

NEW YORK, September 28, 2006 - At a Special Meeting of Stockholders held in
Baltimore, Maryland, Tri-Continental Corporation (NYSE: TY) today announced that
preliminary results indicate that the three incumbent Directors nominated for
re-election by Tri-Continental's Board will be re-elected.

In addition, on a proposal to amend Tri-Continental's charter to reduce the
quorum requirements for future stockholder meetings, the majority of votes cast
were for the proposal. However, a majority of all votes entitled to be cast is
required for approval of the proposal. The Meeting was adjourned in order to
permit stockholders additional time to vote on the charter amendment proposal,
and to receive a report from the independent inspector of election on the
election of directors.

The adjourned meeting will take place on October 5, 2006, at the offices of
Sullivan & Cromwell LLP at 375 Park Ave. New York, NY at 10:00 a.m.
