Tri-Continental Corporation

To the Stockholders:


     During the three months ended September 30, 2002, the stock market
experienced its worst quarter since 1987. In this difficult environment,
Tri-Continental Corporation suffered along with the overall market, returning
-16.53% based on net asset value and -17.92% based on market price. During the
same time period, the Standard & Poor's 500 Composite Stock Index (S&P 500)
returned -17.28%, and the Lipper Closed-End Growth & Income Funds Average
returned -15.96%.

     In the third quarter, investors were rattled by indications that this
year's economic recovery was losing steam. In addition, investors, already
shaken by disclosures of corporate malfeasance and improper financial
accounting, were facing signs that the manufacturing sector was again
contracting and that consumer spending might be faltering. Additionally, higher
oil prices and geopolitical uncertainty further dampened investors' spirits in
what proved to be a dismal quarter. On the positive side, third-quarter
corporate earnings generally improved on a year-over-year basis.

     The Federal Reserve Board chose not to lower interest rates in the third
quarter, but on November 6 it reduced the federal funds rate to 1.25%, a cut of
50 basis points. The Fed hopes to stimulate growth by further lowering borrowing
costs. The rate cut could also provide a psychological boost to investors and
consumers. Consumer confidence has fallen to its lowest level in nine years, due
in part to the weak labor market and concerns over a possible war with Iraq.
Consumer sentiment is something the Fed will be watching closely, particularly
in advance of the holiday shopping season, since continued consumer spending is
crucial to the recovery.

     Despite a discouraging third quarter, the economy is, in fact, expanding,
and we believe the recovery will continue, albeit at a slow pace. If economic
weakness persists, Congress, with midterm elections now behind them, could
realistically consider a fiscal stimulus.

     The stock market has rallied in recent weeks on encouraging earnings news
from some companies, and we hope this is a trend that will continue. In our
view, investors' expectations for the economy and for corporate earnings have
become more realistic, and thus the stock market should begin to operate based
less on emotion and more on fundamentals.

     Given this year's highly negative investment environment, Tri-Continental
will not have a December capital gain payout. Capital gains are realized by
selling stock at a profit, something that is difficult to achieve in a down
market. We realize this is a disappointment to many Stockholders, but we are
hopeful that the stock market has bottomed out, and that it will begin to
recover from this year's declines.

     We thank you for your continued support of Tri-Continental Corporation and
look forward to serving your investment needs for many years to come. A
discussion with your Portfolio Managers, as well as the Corporation's
performance history and portfolio of investments, follows this letter.

By order of the Board of Directors,

Tri-Continental Corporation

INTERVIEW WITH YOUR PORTFOLIO MANAGERS, BEN-AMI GRADWOHL AND DAVID GUY

How did Tri-Continental Corporation perform during the third quarter of 2002?

     For the three months ended September 30, 2002, Tri-Continental posted a
total return of -16.53% based on net asset value and -17.92% based on market
price, compared to a -17.28% return for the Standard and Poor's 500 Composite
Stock Index (S&P 500) and a -15.96% return for the Lipper Closed-End Growth &
Income Funds Average.

What economic and market factors affected Tri-Continental's results during this
time?

     The third quarter was extraordinarily negative for the stock market, which
was dragged down by signs of a weakening economic recovery, continued corporate
accounting worries, and heightened geopolitical uncertainty. Despite the fact
that interest rates are at a 40-year low, the hoped-for recovery in corporate
profits and capital spending has not materialized, and this also negatively
impacted investor sentiment toward equities. Investor fears of a double-dip
recession were fueled by a drop in manufacturing activity (after seven straight
months of growth), as well as by evidence that both consumer confidence and
spending had trended downward. While GDP growth in the second quarter was
revised up to a 1.3% annualized rate, and third-quarter growth came in at 3.1%,
it is clear that the economy's growth rate is slower now compared to its initial
growth spurt in the first quarter of 2002. A major reason the economy is
sluggish is that companies are being extremely cautious in their spending.
Normally, corporate spending on everything from information technology to
equipment is a major engine of economic growth, but with profits weak, even low
interest rates have not convinced many companies to make major financial
commitments while they remain unsure about demand for their products. Throughout
the recession and recovery, the economy has been largely propped up by the
consumer. Record-low interest rates have created a boom in mortgage
refinancings, which has put more money into consumers' hands, and consumers have
responded both by making purchases and by paying down debt. However, this bright
spot was overshadowed in the third quarter by the negative economic news and by
fears of a war with Iraq. The stock market was battered by this confluence of
bad news and uncertainty, posting some of its steepest losses in history.

What was your investment strategy?

     Stocks from every economic sector were hit hard during the third quarter,
even the defensive and value stocks that had consistently outperformed growth
and technology stocks over the past two years. The decline in equity prices was
driven by emotion and a lack of investor faith in both the economy and the
integrity of the American corporation. Given the volatility and lack of upward
momentum in the market, Tri-Continental avoided major over- or underweightings
during the period. The portfolio's largest sector weightings were in capital
goods, consumer staples, and banks. With most sectors of the

Tri-Continental Corporation

INTERVIEW WITH YOUR PORTFOLIO MANAGERS (continued)

economy weak, we did not expect major pockets of growth, except perhaps in the
defense industry. The portfolio did seek out stocks with predictable earnings,
low volatility, and dividend yield. Because of the ongoing war on terrorism and
the possibility of war in Iraq, Tri-Continental's portfolio had a slight
overweighting in defense stocks and defense-related technology stocks.

What sectors of the portfolio contributed most positively to Tri-Continental's
performance?

     Tri-Continental's performance was helped by its underweighting in
information technology. Performance was also helped by the fact that
Tri-Continental's utilities holdings were of higher quality than those in the
index; we avoided unregulated utilities, including merchant power providers, and
instead favored regulated utilities, which performed better on a relative basis.
The portfolio's industrial holdings also contributed positively to performance,
since they tend to be less economically sensitive.

What sectors of the portfolio detracted from performance?

     Few economic sectors were left unscathed during the third quarter, and
stocks declined almost across the board. Tri-Continental's performance was hurt
by its underweighting in the health care sector, one of the few areas to perform
well during the third quarter. Consumer discretionary stocks were poor
performers that detracted from the portfolio's performance.

What is your outlook?

     We expect a period of slow economic recovery, and this is how
Tri-Continental's portfolio is positioned. We do not currently anticipate a
double-dip recession. We think increased spending by the federal government will
help support growth. Also, mortgage refinancings remain popular, and for this
reason consumers should continue to spend. However, we will monitor the recent
sharp decline in consumer confidence, given the important role consumer spending
plays in the economy. We think corporations will begin to make capital
expenditures again, if only to maintain existing infrastructure. However,
companies will be slower to invest in new equipment and technology until their
profits improve and the economic outlook appears more certain. On the bright
side, many companies have taken advantage of low interest rates to relieve their
debt burden. Over the short term, we expect the stock market will remain
volatile until clear and consistent signs of an economic recovery are more
discernible, and until the geopolitical situation in the Middle East stabilizes.
Nevertheless, the stock market should react well to signs of a strengthening
economy and improving corporate earnings.

Tri-Continental Corporation

Stockholder Services

     Tri-Continental provides a number of services to make maintaining an
investment in its Common Stock more convenient.

Automatic Dividend Investment and Cash Purchase Plan. Stockholders may
automatically purchase additional shares with dividends and capital gains. There
isno charge for this service. Stockholders may alsopurchase additional shares
directly from the Corporation. There is a service fee of a maximum of $2.00 for
each cash purchase transaction.

Automatic Cash Withdrawal Plan. Stockholders who hold common shares with a
market value of $5,000 or more may elect to receive a fixed amount from their
investment at regular intervals by selling their shares to the Corporation.

Traditional Individual Retirement Account (IRA). Stockholders who have earned
income and are under age 701/2 may contribute up to $3,000 per year to a
Traditional IRA for 2002. A working or non-working spouse may also contribute up
to $3,000 to a separate Traditional IRA for 2002. Individuals who reach age 50
prior to the end of a taxable year may make additional "catch-up contributions"
to a Traditional IRA of up to $500 (increasing to $1,000 for years beginning
after 2005). Contributions to a Traditional IRAmay be deductible or
non-deductible. If you are single and NOT covered by an employer's retirement
plan, your contribution will always be deductible. For individuals who are
covered by a plan, contributions will be deductible if your modified adjusted
gross income (MAGI) in 2002 is less than $34,000. For spouses who are both
covered by a plan, contributions will be fully deductible if your MAGI is less
than $54,000. If one spouse does not work or is not covered by a retirement
plan, that spouse's contribution will be fully deductible provided your
household MAGI does not exceed $150,000. If your contribution is not deductible,
you may still take advantage of the tax-deferred accumulation of earnings in
your Traditional IRA.

Rollover IRA. You may be eligible to roll over a distribution of assets received
from another IRA, a qualified employee benefit plan, or tax-deferred annuity
into a Rollover IRA with Tri-Continental. To avoid a tax penalty, the transfer
to a Rollover IRA must occur within 60 days of receipt of the qualifying
distribution. If you do not make a direct transfer of a distribution from a
qualified employee benefit plan or a tax-deferred annuity to a Rollover IRA, the
payor of the distribution must withhold 20% of the distribution.

Roth IRA. You (and a working or non-working spouse) may each make an after-tax
contribution of up to $3,000 per year to a Roth IRAprovided you have earned
income and meet the eligibility requirements. Your MAGI must be less than
$95,000 (individuals) or $150,000 (married couples) to be eligible to make a
full contribution to a Roth IRA. You are eligible to make a partial Roth
IRAcontribution if your MAGI is below $110,000 (individuals) or $160,000
(married couples). Total combined contributions to a Roth IRA and a Traditional
IRA cannot exceed $3,000 in any year. Individuals who reach age 50 prior to the
end of a taxable year may make additional "catch-up contributions" to a Roth IRA
of up to $500 (increasing to $1,000 for years beginning after 2005). Earnings
grow tax-free and will be distributed to you tax-free and penalty-free provided
that you hold your account for at least five years and you take the distribution
either after age 591/2, for disability, upon death, or to make a first-time home
purchase (up to $10,000). Unlike a Traditional IRA, you may contribute to a Roth
IRA even if you are over age 701/2 (if you have earned income), and you are not
required to take minimum distributions at age 701/2. You may convert an existing
Traditional IRAto a Roth IRAto take advantage of tax-free distributions. You
must pay taxes on any earnings and deductible contributions in your Traditional
IRAwhen converting it to a Roth IRA. Talk to your financial advisor for more
details on converting your Traditional IRA.

Retirement Planning -- Qualified Plans. Unincorporated businesses and the
self-employed may take advantage of the same benefits in their retirement plans
that are available to corporations. Contribution levels can go as high as 100%
of earned income (reduced by plan contributions), to a maximum of $40,000 per
participant. For retirement plan purposes, no more than $200,000 may be taken
into account as earned income under the plan in 2002 and future years (subject
to adjustments to reflect cost of living increases). Social Security integration
and employee vesting schedules are also available as options in the
Tri-Continental prototype retirement plans. Although you already may be
participating in an employer's retirement plan, you may be eligible to establish
another plan based upon income from other sources, such as director's fees.

Retirement Plan Services provides information about our prototype retirement
plans. The toll-free telephone number is (800) 445-1777 in the US and (212)
682-7600 outside the US.

Gifts Free of Federal Tax are often made using Tri-Continental Common Stock. You
may give as much as $11,000 a year to as many individuals as desired free of
federal gift tax, and a married couple may give up to $22,000 a year.

Stock Repurchase Program. On November 15, 2001, the Board of Directors
authorized the renewal of Tri-Continental's ongoing share repurchase program.
The program authorizes the Corporation to repurchase up to 7.5% of the
Corporation's shares over a 12-month period, provided that the discount of a
share's market price to its net asset value ("NAV") remains wider than 10%. The
Board's decision benefits all stockholders, allowing them to continue to enjoy
the advantages of Tri-Continental's closed-end structure, while increasing the
NAV of the Corporation's outstanding shares.

     Between November 15, 2001 and September 30, 2002, 8.1 million shares were
repurchased. This is approximately 6.3% of the shares outstanding at the
beginning of the period. The repurchase of additional shares is expected to
continue between October and November 2002, as long as the discount remains
above 10%.

                                                                               9
