IMPORTANT PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------

Performance data quoted herein represents past performance. Past performance
does not guarantee or indicate future results. Investment return and principal
value of an investment will fluctuate so that an investor's shares, when sold,
may be worth more or less than their original cost. Current performance may be
higher or lower than the performance data quoted. Total returns for the Fund as
of the most recent month-end will be made available at www.tricontinental.com by
the seventh business day following that month-end.

The Net Asset Value and Market Price investment results assume the reinvestment
of all distributions. The Lipper Closed-End Growth & Income Funds Average and
the S&P 500 are an unmanaged average and benchmark, respectively, that assume
the reinvestment of all distributions. The S&P 500 excludes the effect of fees.
Investors cannot invest directly in an average or index.

(1)   Calculations are based upon information provided by FactSet as of 2/28/06
      for the securities held in the Corporation.

(2)   Price/Earnings Ratio is the "multiple" of earnings at which a stock sells,
      determined by dividing current stock price by estimated earnings per
      share, adjusted for stock splits. A higher "multiple" indicates investors
      have greater expectations for future growth. The weighted average is the
      mean of the price/earnings ratios of all securities held in
      Tri-Continental's portfolio, weighted by the percent of equity.

(3)   Price/Book Ratio is the comparison of a stock's market value to the value
      of total assets less total liabilities (book value), deter- mined by
      dividing current stock price by common stockholder equity per share,
      adjusted for stock splits. The weighted average is the mean of the
      price/book ratios of all securities held in Tri- Continental's portfolio,
      weighted by the percent of equity.

A WORD ABOUT RISK
- --------------------------------------------------------------------------------

The net asset value of shares may not always correspond to the market price of
such shares. Shares of many closed-end funds frequently trade at a discount from
their net asset value. Tri-Continental Corporation is subject to stock market
risk, which is the risk that stock prices overall will decline over short or
long periods, adversely affecting the value of an investment in the Fund.

There is no guarantee that the Fund's investment goals/objective will be met,
and you could lose money.
