(1)   Stockholders participating in the Corporation's investment plans pay a
      maximum $2.00 fee per transaction. See "Investment Plans and Other
      Services--Automatic Dividend Investment and Cash Purchase Plan" for a
      description of the investment plans and services.

      The purpose of the table above is to assist you in understanding the
various costs and expenses you will bear directly or indirectly. For more
complete descriptions of the various costs and expenses, see "Management of the
Corporation" and "Investment Plans and Other Services--Automatic Dividend
Investment and Cash Purchase Plan."

      The following example illustrates the costs you would pay on a $1,000
investment, assuming a 5% annual return:



                                               1 Year     3 Years   5 Years   10 Years

Tri-Continental Corporation Common Stock         $7         $22       $38        $85


      The example does not represent actual or anticipated costs, which may be
more or less than those shown. Moreover, the Corporation's actual rate of return
may be more or less than the hypothetical 5% return shown in the example.

                               PROSPECTUS SUMMARY

      The following is qualified in its entirety by the more detailed
information included elsewhere in this Prospectus.

      This Prospectus applies to shares of Common Stock of the Corporation. The
Corporation invests primarily for the longer term and has no Charter
restrictions with respect to such investments. Over the years the Corporation's
objective has been to produce future growth of both capital and income while
providing reasonable current income. There can be no assurance that this
objective will be achieved. While common stocks have made up the bulk of
investments, assets may be held in cash or invested in all types of securities
in whatever amounts or proportions J. & W. Seligman & Co. Incorporated (the
"Manager") believes best suited to current and anticipated economic and market
conditions. These may include preferred stock, debt securities, repurchase
agreements, options, illiquid securities and securities of foreign issuers, each
of which could involve certain risks. See "Investment Objective and Other
Policies and Related Risks."

      The Manager manages the investment of the assets of the Corporation and
administers its business and other affairs pursuant to a Management Agreement
approved by the Board of Directors and the stockholders of the Corporation. The
Manager also serves as manager of twenty-one other U.S. registered investment
companies which, together with the Corporation, make up the "Seligman Group of
Funds." The aggregate assets of the Seligman Group of Funds at March 31, 2003
were approximately $10.8 billion. The Manager also provides investment
management or advice to institutional and other accounts having a value at March
31, 2003 of approximately $7.1 billion. The Manager's fee is based in part on
the average daily net assets of the Corporation. The management fee rate for
2002 was equivalent to .40% of the Corporation's average daily net investment
assets. See "Management of the Corporation."

      Shares of Common Stock covered by this Prospectus may be purchased from
time to time by Seligman Data Corp. ("SDC"), the Plan service agent for
Automatic Dividend Investment and Cash Purchase Plans, Individual Retirement
Accounts ("IRAs"), Retirement Plans for Self-Employed Individuals, Partnerships
and Corporations, the J. & W. Seligman & Co. Incorporated Matched Accumulation
Plan and the Seligman Data Corp. Employees' Thrift Plan (collectively, the
"Plans"), as directed by participants, and may be sold from time to time by the
Plan service agent for participants in Systematic Withdrawal Plans. See
"Investment Plans and Other Services." Shares will be purchased for the Plans on
the New York Stock Exchange or elsewhere when the market price of the Common
Stock is equal to or less than its net asset value, and any brokerage
commissions applicable to such purchases will be charged pro rata to the Plan
participants. Shares will be purchased for the Plans from the Corporation at net
asset value when the net asset value is lower than the market price, all as more
fully described in this Prospectus.

      On November 21, 2002, the Board of Directors authorized the renewal of the
Corporation's ongoing share repurchase plan. The program authorizes the
Corporation to repurchase over a 12-month period up to 7.5% of its then
outstanding Common Stock, provided that the excess of net asset value of a share
of Common Stock over its market price remains greater than 10%. The shares
repurchased under this program are cancelled, increasing the number of
authorized but unissued shares available for issuance to participants in the
Plans. The stock repurchase program seeks, among other things, to moderate the
growth in the number of shares outstanding, increase the net asset value of the
Corporation's outstanding shares, reduce the dilutive impact on stockholders who
do not take capital gains distributions in additional shares and increase the
liquidity of the Corporation's Common Stock in


                                       4


the marketplace. Shares acquired by the Corporation from participants in the
Systematic Withdrawal Plan and other stockholder plans, as well as shares
purchased for the Corporation in the open market to meet demand under the
Automatic Dividend and Cash Purchase Plan, are counted towards the 7.5%
repurchase limit under the program. As of March 31, 2003, 3,475,296 shares, or
approximately 2.8% of the shares outstanding on November 21, 2002, had been
repurchased under the program.

                                 THE CORPORATION

      The Corporation is a Maryland corporation formed in 1929 by the
consolidation of two predecessor corporations. It is registered under the
Investment Company Act of 1940, as amended (the "1940 Act"), as a diversified

Stock is listed on the New York Stock Exchange under the symbol "TY." The
average weekly trading volume on that and other exchanges during 2002 was
423,166 shares. The Corporation's Common Stock has historically been traded on
the market at less than net asset value. As of March 31, 2003, the Corporation
had 122,562,046 shares of Common Stock outstanding and net assets attributable
to Common Stock of $1,835,992,028.

                              FINANCIAL HIGHLIGHTS

      The Corporation's financial highlights for the years presented below have
been audited by Deloitte & Touche LLP, independent auditors. This information,
which is derived from the financial and accounting records of the Corporation,
should be read in conjunction with the financial statements and notes contained
in the Corporation's 2002 Annual Report, which may be obtained from the
Corporation as provided on the cover page of this Prospectus.

      "Per share operating performance" data is designed to allow you to trace
the operating performance, on a per Common share basis, from the beginning net
asset value to the ending net asset value so that you can understand what effect
the individual items have on your investment, assuming it was held throughout
the year. Generally, the per share amounts are derived by converting the actual
dollar amounts incurred for each item, as disclosed in the financial statements,
to their equivalent per Common share amount, using average shares outstanding.

      The total investment return based on market value measures the
Corporation's performance assuming you purchased shares of the Corporation at
the market value as of the beginning of the year, invested dividends and capital
gains paid as provided for in the Corporation's Automatic Dividend Investment
and Cash Purchase Plan, and then sold your shares at the closing market value
per share on the last day of the year. The computation does not reflect any
sales commissions you may incur in purchasing or selling shares of the
Corporation. The total investment return based on net asset value is similarly
computed except that the Corporation's net asset value is substituted for the
corresponding market value.

            INVESTMENT OBJECTIVE AND OTHER POLICIES AND RELATED RISKS

      The Corporation invests primarily for the longer term and has no Charter
restrictions with respect to such investments. Over the years, the Corporation's
investment objective has been to produce future growth of both capital and
income while providing reasonable current income. There can be no assurance that
this objective will be achieved. While common stocks have made up the bulk of
investments, assets may be held in cash or invested in all types of securities,
that is, in bonds, debentures, notes, preferred and common stocks, rights and
warrants (subject to limitations as set forth in the SAI), and other securities,
in whatever amounts or proportions the Manager believes best suited to current
and anticipated economic and market conditions.

      The management's present investment policies, in respect to which it has
freedom of action, are:

            (1) it keeps investments in individual issuers within the limits
      permitted diversified companies under the 1940 Act (i.e., 75% of its total
      assets must be represented by cash items, government securities,
      securities of other investment companies, and securities of other issuers
      which, at the time of investment, do not exceed 5% of the Corporation's
      total assets at market value in the securities of any issuer and do not
      exceed 10% of the voting securities of any issuer);

            (2) it does not make investments with a view to exercising control
      or management except that it has an investment in SDC;

            (3) it ordinarily does not invest in other investment companies, but
      it may purchase up to 3% of the voting securities of such investment
      companies, provided purchases of securities of a single investment company
      do not exceed in value 5% of the total assets of the Corporation and all
      investments in investment company securities do not exceed 10% of total
      assets; and

            (4) it has no fixed policy with respect to portfolio turnover and
      purchases and sales in the light of economic, market and investment
      considerations. The portfolio turnover rates for the ten fiscal years
      ended December 31, 2002 are shown under "Financial Highlights."

The foregoing investment objective and policies may be changed by management
without stockholder approval, unless such a change would change the
Corporation's status from a "diversified" to a "non-diversified" company under
the 1940 Act.

      The Corporation's stated fundamental policies relating to the issuance of
senior securities, the borrowing of money, the underwriting of securities of
other issuers, the concentration of investments in a particular industry or
groups of industries, the purchase or sale of real estate and real estate
mortgage loans, the purchase or sale of commodities or commodity contracts, and
the making of loans may not be changed without a vote of stockholders. A more
detailed description of the Corporation's investment policies, including a list
of those restrictions on the Corporation's investment activities which cannot be
changed without such a vote, appears in the SAI. Within the limits of these
fundamental policies, management has reserved freedom of action.

      Repurchase Agreements: The Corporation may enter into repurchase
agreements with respect to debt obligations which could otherwise be purchased
by the Corporation. A repurchase agreement is an instrument under which the
Corporation may acquire an underlying debt instrument and simultaneously obtain
the commitment of the seller (a commercial bank or a broker or dealer) to
repurchase the security at an agreed upon price and date within a number of days
(usually not more than seven days from the date of purchase). The value


                                       10


of the underlying securities will be at least equal at all times to the total
amount of the repurchase obligation, including the interest factor. The
Corporation will make payment for such securities only upon physical delivery or
evidence of book transfer to the account of the Corporation's custodian.
Repurchase agreements could involve certain risks in the event of default or
insolvency of the other party, including possible delays or restrictions upon
the Corporation's ability to dispose of the underlying securities.

      Illiquid Securities: The Corporation may invest up to 15% of its net
investment assets in illiquid securities, including restricted securities (i.e.,
securities not readily marketable without registration under the Securities Act
of 1933, as amended (the "1933 Act")) and other securities that are not readily
marketable. The Corporation may purchase restricted securities that can be
offered and sold to "qualified institutional buyers" under Rule 144A of the 1933
Act, and the Corporation's Board of Directors may determine, when appropriate,
that specific Rule 144A securities are liquid and not subject to the 15%
limitation on illiquid securities. Should this determination be made, the Board
of Directors will carefully monitor the security (focusing on such factors,
among others, as trading activity and availability of information) to determine
that the Rule 144A security continues to be liquid. This investment practice
could have the effect of increasing the level of illiquidity in the Corporation,
if and to the extent that qualified institutional buyers become for a time
uninterested in purchasing Rule 144A securities.

      Foreign Securities: The Corporation may invest in commercial paper and
certificates of deposit issued by foreign banks and may invest in other
securities of foreign issuers directly or through American Depositary Receipts
("ADRs"), American Depositary Shares ("ADSs"), European Depositary Receipts
("EDRs") or Global Depositary Receipts ("GDRs") (collectively, "Depositary
Receipts"). Foreign investments may be affected favorably or unfavorably by
changes in currency rates and exchange control regulations. There may be less
information available about a foreign company than about a U.S. company and
foreign companies may not be subject to reporting standards and requirements
comparable to those applicable to U.S. companies. Foreign securities may not be
as liquid as U.S. securities. Securities of foreign companies may involve
greater market risk than securities of U.S. companies, and foreign brokerage
commissions and custody fees are generally higher than those in the United
States. Investments in foreign securities may also be subject to local economic
or political risks, political instability and possible nationalization of
issuers. ADRs and ADSs are instruments generally issued by domestic banks or
trust companies that represent the deposits of a security of a foreign issuer.
ADRs and ADSs may be publicly traded on exchanges or over-the-counter in the
United States and are quoted and settled in dollars at a price that generally
reflects the dollar equivalent of the home country share price. EDRs and GDRs
are typically issued by foreign banks or trust companies and traded in Europe.
Depositary Receipts may be issued under sponsored or unsponsored programs. In
sponsored programs, the issuer has made arrangements to have its securities
traded in the form of a Depositary Receipt. In unsponsored programs, the issuers
may not be directly involved in the creation of the program. Although regulatory
requirements with respect to sponsored and unsponsored programs are generally
similar, the issuers of securities represented by unsponsored Depositary
Receipts are not obligated to disclose material information in the United States
and, therefore, the import of such information may not be reflected in the
market value of such receipts. The Corporation may invest up to 10% of its total
assets in foreign securities that it holds directly, but this 10% limit does not
apply to foreign securities held through Depositary Receipts or to commercial
paper and certificates of deposit issued by foreign banks.

      Leverage: Senior securities issued or money borrowed to raise funds for
investment have a prior fixed dollar claim on the Corporation's assets and
income. Any gain in the value of securities purchased or in income received in
excess of the cost of the amount borrowed or interest or dividends payable
causes the net asset value


                                       11


of the Corporation's Common Stock or the income available to it to increase more
than otherwise would be the case. Conversely, any decline in the value of
securities purchased or income received on them to below the asset or income
claims of the senior securities or borrowed money causes the net asset value of
the Common Stock or income available to it to decline more sharply than would be
the case if there were no prior claim. Funds obtained through senior securities
or borrowings thus create investment opportunity, but they also increase
exposure to risk. This influence ordinarily is called "leverage." As of March
31, 2003, the only senior securities of the Corporation outstanding were 752,740
shares of its $2.50 Cumulative Preferred Stock, $50 par value. Based on its
March 31, 2003 asset value, the Corporation's portfolio requires an annual
return of 0.10% in order to cover dividend payments on the Preferred Stock. The
following table illustrates the effect of leverage relating to presently
outstanding Preferred Stock on the return available to a holder of the
Corporation's Common Stock.

      The purpose of the table above is to assist you in understanding the
effects of leverage. The percentages appearing in the table do not represent
actual or anticipated returns, which may be greater or less than those shown.

                          MANAGEMENT OF THE CORPORATION

      The Manager: In accordance with the applicable laws of the State of
Maryland, the Board of Directors provides broad supervision over the affairs of
the Corporation. Pursuant to a Management Agreement approved by the Board and
the stockholders, the Manager manages the investment of the assets of the
Corporation and administers its business and other affairs. In that connection,
the Manager makes purchases and sales of portfolio securities consistent with
the Corporation's investment objective and policies.

      The Manager also serves as manager of twenty-one other U.S. registered
investment companies of the Seligman Group of Funds. These other companies are:
Seligman Capital Fund, Inc., Seligman Cash Management Fund, Inc., Seligman
Common Stock Fund, Inc., Seligman Communications and Information Fund, Inc.,
Seligman Frontier Fund, Inc., Seligman Growth Fund, Inc., Seligman Global Fund
Series, Inc., Seligman High Income Fund Series, Seligman Income and Growth Fund,
Inc., Seligman Investment Grade Fixed Income Fund, Inc., Seligman Municipal Fund
Series, Inc., Seligman Municipal Series Trust, Seligman New Jersey Municipal
Fund, Inc., Seligman New Technologies Fund, Inc., Seligman New Technologies Fund
II, Inc., Seligman Pennsylvania Municipal Fund Series, Seligman Portfolios,
Inc., Seligman Quality Municipal Fund, Inc., Seligman Select Municipal Fund,
Inc., Seligman Time Horizon/Harvester Series, Inc. and Seligman Value Fund
Series, Inc. The address of the Manager is 100 Park Avenue, New York, NY 10017.

      As compensation for the services performed and the facilities and
personnel provided by the Manager, the Corporation pays to the Manager promptly
after the end of each month a fee, calculated on each day during such month,
equal to the Applicable Percentage of the daily net assets of the Corporation at
the close of business on the previous business day. The term "Applicable
Percentage" means the amount (expressed as a percentage and rounded to the
nearest one millionth of one percent) obtained by dividing (i) the Fee Amount by
(ii) the Fee Base. The term "Fee Amount" means the sum on an annual basis of:


                                       12


                  .45 of 1% of the first $4 billion of Fee Base
                  .425 of 1% of the next $2 billion of Fee Base
                  .40 of 1% of the next $2 billion of Fee Base, and
                  .375 of 1% of the Fee Base in excess of $8 billion.

The term "Fee Base" as of any day means the sum of the net assets at the close
of business on the previous day of each of the investment companies registered
under the 1940 Act for which the Manager or any affiliated company acts as
investment adviser or manager (including the Corporation).

      Ben-Ami Gradwohl, Ph.D., a Managing Director of the Manager, has been Vice
President and Co-Portfolio Manager of the Corporation since October 2001. Mr.
Gradwohl is also Vice President and Co-Portfolio Manager of Seligman Common
Stock Fund, Inc., and Seligman Income and Growth Fund, Inc., and Vice President

Seligman as a Managing Director in January 2000. From 1996 to 1999, he was a
Portfolio Manager at Nicholas-Applegate Capital Management. During his tenure
there, he managed U.S. systematic large-cap portfolios, tax-efficient
strategies, an aggressive U.S. equity offshore fund, a long-short hedge fund and
international equity investments.

      David Guy, Ph.D., a Managing Director of the Manager, has been Vice
President and Co-Portfolio Manager of the Corporation since October 2001. Mr.
Guy is also Vice President and Co-Portfolio Manager of Seligman Common Stock
Fund, Inc., and Vice President of SPI and Co-Portfolio Manager of SPI's Seligman
Common Stock Portfolio. Mr. Guy joined Seligman as a Managing Director in

securities in the Systematic Investment Group at Nicholas-Applegate Capital
Management. During the winter semester of 1997, he was a Visiting Associate
Professor with the Department of Statistics at the University of California,
Riverside.

      The Corporation pays all its expenses other than those assumed by the
Manager, including brokerage commissions, fees and expenses of independent
attorneys and auditors, taxes and governmental fees, cost of stock certificates,
expenses of printing and distributing prospectuses, expenses of printing and
distributing reports, notices and proxy materials to stockholders, expenses of
printing and filing reports and other documents with governmental agencies,
expenses of stockholders' meetings, expenses of corporate data processing and
related services, stockholder record-keeping and stockholder account services,
fees and disbursements of transfer agents and custodians, expenses of disbursing
dividends and distributions, fees and expenses of directors of the Corporation
not employed by the Manager or its affiliates, insurance premiums and
extraordinary expenses such as litigation expenses.

      The Management Agreement provides that it will continue in effect until
December 29 of each year if such continuance is approved in the manner required
by the 1940 Act (i.e., by a vote of a majority of the Board of Directors or of
the outstanding voting securities of the Corporation and by a vote of a majority
of Directors who are not parties to the Management Agreement or interested
persons of any such party) and if the Manager shall not have notified the
Corporation at least 60 days prior to December 29 of any year that it does not
desire such continuance. The Management Agreement may be terminated by the
Corporation, without penalty, on 60 days' written notice to the Manager and will
terminate automatically in the event of its assignment.

                          DESCRIPTION OF CAPITAL STOCK

      (a) Dividend Rights: Common Stockholders are entitled to receive dividends
only if and to the extent declared by the Board of Directors and only after (i)
such provisions have been made for working capital and for reserves as the Board
may deem advisable, (ii) full cumulative dividends at the rate of $0.625 per
share per quarterly dividend period have been paid on the Preferred Stock for
all past quarterly periods and have been provided for the current quarterly
period, and (iii) such provisions have been made for the purchase or for the
redemption (at a price of $55 per share) of the Preferred Stock as the Board may
deem advisable. In any event, no dividend may be declared upon the Common Stock
unless, at the time of such declaration, the net assets of the Corporation,
after deducting the amount of such dividend and the amount of all unpaid
dividends declared on the Preferred Stock, shall be at least equal to $100 per
outstanding share of Preferred Stock. The equivalent figure was $2,485.78 at
March 31, 2003.

      (b) Voting Rights: The Preferred Stock is entitled to two votes and the
Common Stock is entitled to one vote per share at all meetings of stockholders.
In the event of a default in payments of dividends on the Preferred Stock
equivalent to six quarterly dividends, the Preferred Stockholders are entitled,
voting separately as a class to the exclusion of Common Stockholders, to elect
two additional directors, such right to continue until all arrearages have been
paid and current Preferred Stock dividends are provided for. Notwithstanding any
provision of law requiring any action to be taken or authorized by the
affirmative vote of the holders of a designated portion of all the shares or of
the shares of each class, such action shall be effective if taken or authorized
by the affirmative vote of a majority of the aggregate number of the votes
entitled to vote thereon, except that a class vote of Preferred Stockholders is
also required to approve certain actions adversely affecting their rights. Any
change in the Corporation's fundamental policies may also be authorized by the
vote of 67% of the votes present at a meeting if the holders of a majority of
the aggregate number of votes entitled to vote are present or represented by
proxy.

      Consistent with the requirements of Maryland law, the Corporation's
Charter provides that the affirmative vote of two-thirds of the aggregate number
of votes entitled to be cast thereon shall be necessary to authorize any of the
following actions: (i) the dissolution of the Corporation; (ii) a merger or
consolidation of the Corporation (in which the Corporation is not the surviving
corporation) with (a) an open-end investment company or (b) a closed-end
investment company, unless such closed-end investment company's Articles of
Incorporation require a two-thirds or greater proportion of the votes entitled
to be cast by such company's stock to approve the types of transactions covered
by clauses (i) through (iv) of this paragraph; (iii) the sale of all or
substantially all of the assets of the Corporation to any person (as such term
is defined in the 1940 Act); or (iv) any amendment of the Charter of this
Corporation which makes any class of the Corporation's stock a redeemable
security (as such term is defined in the 1940 Act) or reduces the two-thirds
vote required to authorize the actions listed in this paragraph. This could have
the effect of delaying, deferring or preventing changes in control of the
Corporation.

      (c) Liquidation Rights: In the event of any voluntary or involuntary
liquidation, dissolution or winding up of the Corporation, after payment to the
Preferred Stockholders of an amount equal to $50 per share plus dividends
accrued or in arrears, the Common Stockholders are entitled, to the exclusion of
the Preferred Stockholders, to share ratably in all the remaining assets of the
Corporation available for distribution to stockholders.

      (d) Other Provisions: Common Stockholders do not have preemptive,
subscription or conversion rights, and are not liable for further calls or
assessments. The Corporation's Board of Directors (other than any directors who
may be elected to represent Preferred Stockholders as described above) are
classified as nearly as possible


                                       14


into three equal classes with a maximum three-year term so that the term of one
class of directors expires annually. Such classification provides continuity of
experience and stability of management while providing for the election of a
portion of the Board of Directors each year. Such classification could have the
effect of delaying, deferring or preventing changes in control of the
Corporation.

      The Board of Directors may classify or reclassify any unissued stock of
any class with or without par value (including Preferred Stock and Common Stock)
into one or more classes of preference stock on a parity with, but not having
preference or priority over, the Preferred Stock by fixing or altering before
the issuance thereof the designations, preferences, voting powers, restrictions
and qualifications of, the fixed annual dividends on, the times and prices of
redemption, the terms of conversion, the number and/or par value of the shares
and other provisions of such stock to the full extent permitted by the laws of
Maryland and the Corporation's Charter. Stockholder approval of such action is
not required.

                             DESCRIPTION OF WARRANTS

      The Corporation's Charter and Warrant certificates provide that each
Warrant represents the right during an unlimited time to purchase one share of
Common Stock at a price of $22.49 per share, subject to increase in the number
of shares purchasable and adjustment of the price payable pursuant to provisions
of the Charter requiring such adjustments whenever the Corporation issues any
shares of Common Stock at a price less than the Warrant purchase price in effect
immediately prior to issue. Each Warrant presently entitles the holder to
purchase 22.50 shares of Common Stock at $1.00 per share. There were 12,970
Warrants outstanding at March 31, 2003. Fractional shares of Common Stock are
not issued upon the exercise of Warrants. In lieu thereof, the Corporation
issues scrip certificates representing corresponding fractions of the right to
receive a full share of Common Stock if exchanged by the end of the second
calendar year following issuance or of the proceeds of the sale of a full share
if surrendered during the next four years thereafter.

                         COMPUTATION OF NET ASSET VALUE

      Net asset value per share of Common Stock is determined by dividing the
current value of the assets of the Corporation less its liabilities and the
prior claim of the Preferred Stock by the total number of shares of Common Stock
outstanding. Securities owned by the Corporation for which market quotations are
readily available are valued at current market value or, in their absence, fair
value determined in accordance with procedures approved by the Board of
Directors. Securities traded on national exchanges are valued at the last sales
prices, or in their absence and in the case of over-the-counter securities, a
mean of bid and asked prices. United Kingdom securities and securities for which
there are no recent sales transactions are valued based on quotations provided
by primary market makers in such securities. Any securities for which recent
market quotations are not readily available are valued at fair value determined
in accordance with procedures approved by the Board of Directors. Short-term
holdings maturing in 60 days or less are generally valued at amortized cost if
their original maturity was 60 days or less. Short-term holdings with more than
60 days remaining to maturity will be valued at current market value until the
61st day prior to maturity, and will then be valued on an amortized cost basis
based on the value of such date unless the Board determines that this amortized
cost value does not represent fair market value.

      All assets and liabilities initially expressed in foreign currencies will
be converted into U.S. dollars by a pricing service based upon the mean of the
bid and asked prices of such currencies against the U.S. dollar quoted by a
major bank which is a regular participant in the institutional foreign exchange
markets.


                                       15


      Net asset value of the Common Stock is determined daily, Monday through
Friday, as of the close of regular trading on the New York Stock Exchange
(normally, 4:00 p.m. Eastern time) each day the New York Stock Exchange is open
for trading.

                            DIVIDEND POLICY AND TAXES

      Dividends: Dividends are paid quarterly on the Preferred Stock and on the
Common Stock in amounts representing substantially all of the net investment
income earned each year. Payments on the Preferred Stock are in a fixed amount,
but payments on the Common Stock vary in amount, depending on investment income
received and expenses of operation. Substantially all of any taxable net gain
realized on investments is paid to Common Stockholders at least annually in
accordance with requirements under the Internal Revenue Code of 1986, as
amended, and other applicable statutory and regulatory requirements. The
Corporation has a substantial capital loss carry-forward that is available for
offset against future net capital gains, expiring in various amounts through
2010. Accordingly, no capital gain distributions are expected to be paid to
shareholders until net capital gains have been realized in excess of the
available capital loss carry-forward.

      Unless SDC is otherwise instructed by you, dividends on the Common Stock
are paid in cash and capital gain distributions are paid in book shares of
Common Stock which are entered in your Tri-Continental account as "book
credits." Long-term gain distributions ordinarily are paid in shares of Common
Stock, or, at your option, 75% in book shares and 25% in cash, or, in the
alternative, 100% in cash. Shares distributed in payment of gain distributions
are valued at market price or at net asset value, whichever is lower, on the
valuation date. Dividends and capital gain distributions will generally be
taxable to you in the year in which they are declared by the Corporation if paid
before February 1 of the following year. Distributions or dividends received by
you will have the effect of reducing the net asset value of the shares of the
Corporation by the amount of such distributions. If the net asset value of
shares is reduced below your cost by a distribution, the distribution will be
taxable as described below even though it is in effect a return of capital.

      Taxes: The Corporation intends to continue to qualify and elect to be
treated as a regulated investment company under the Internal Revenue Code. As a
regulated investment company, the Corporation will generally be exempt from
federal income taxes on net investment income and capital gains that it
distributes to stockholders provided that at least 90% of its investment income
and net short-term capital gains are distributed to stockholders each year.

      Dividends on Common or Preferred Stock representing net investment income
and distributions of net short-term capital gains are taxable to stockholders as
ordinary income, whether received in cash or invested in additional shares and,
to the extent designated as derived from the Corporation's dividend income that
would be eligible for the dividends received deduction if the Corporation were
not a regulated investment company, they are eligible, subject to certain
restrictions, for the 70% dividends received deduction for corporations.
Distributions of net capital gain (i.e., the excess of net long-term capital
gains over any net short-term capital losses) are taxable as long-term capital
gain, whether received in cash or invested in additional shares, regardless of
how long you have held your shares. Such distributions are not eligible for the
dividends received deduction allowed to corporate stockholders. If you receive
distributions in the form of additional shares issued by the Corporation, you
will be treated for federal income tax purposes as having received a
distribution in an amount equal to the fair market value on the date of
distribution of the shares received. You will be subject to federal income tax
on net capital gains at a maximum rate of 20% if designated as derived from the
Corporation's capital gains from property held by the Corporation for more than
one year.


                                       16


      Any gain or loss you realize upon a sale or redemption of Common or
Preferred Stock, if you are not a dealer in securities, will generally be
treated as a long-term capital gain or loss if you held your shares for more
than one year and as a short-term capital gain or loss if you held your shares
for one year or less. However, if shares on which a long-term capital gain
distribution has been received are subsequently sold or redeemed and such shares
have been held for six months or less, any loss you realize will be treated as
long-term capital loss to the extent that it offsets the long-term capital gain
distribution. No loss will be allowed on the sale or other disposition of shares
of the Corporation if, within a period beginning 30 days before the date of such
sale or disposition and ending 30 days after such date, you acquire (such as
through the Automatic Dividend Investment and Cash Purchase Plan), or enter into
a contract or option to acquire, securities that are substantially identical to
the shares of the Corporation. Net capital gain of a corporate stockholder is
taxed at the same rate as ordinary income.

      The Corporation will generally be subject to an excise tax of 4% on the
amount by which distributions to stockholders fall short of certain required
levels, such that income or gain is not taxable to stockholders in the calendar
year in which it was earned by the Corporation. Furthermore, dividends declared
in October, November or December payable to stockholders of record on a
specified date in such a month and paid in the following January will be treated
as having been paid by the Corporation and received by you in December. Under
this rule, therefore, you may be taxed in one year on dividends or distributions
actually received in January of the following year.

      The tax treatment of the Corporation and of stockholders under the tax
laws of the various states may differ from the federal tax treatment. You are
urged to consult your own tax advisor regarding specific questions as to
federal, state or local taxes.

      The Corporation is required to withhold and remit to the U.S. Treasury a
portion of taxable dividends and other reportable payments paid on your account
if you provide the Corporation with either an incorrect Taxpayer Identification
Number or no number at all or you fail to certify that you are not subject to
such withholding. You should be aware that, under regulations promulgated by the
Internal Revenue Service, the Corporation may be fined $50 annually for each
account for which a certified Taxpayer Identification Number is not provided.
The Corporation may charge you a service fee of up to $50 for accounts not
having a certified Taxpayer Identification Number. Certificates will not be
issued unless an account is certified.

                       INVESTMENT PLANS AND OTHER SERVICES

Automatic Dividend Investment and Cash Purchase Plan

      The Automatic Dividend Investment and Cash Purchase Plan is available for
any Common stockholder who wishes to purchase additional shares of the
Corporation's Common Stock with dividends or other cash payments on shares
owned, with cash dividends paid by other corporations in which stock is owned or
with cash funds. Details of the services offered under the Plan are given in the
Authorization Form appearing in this Prospectus. Under the Plan, you appoint the
Corporation as your purchase agent to receive or invest such dividends and cash
funds forwarded by you for your accounts in additional shares of the
Corporation's Common Stock (after deducting a service charge), as described
under "Method of Purchase" below. Funds forwarded by you under the Plan should
be made payable to Tri-Continental Corporation and mailed to Tri-Continental
Corporation, P.O. Box 9766, Providence, RI 02940-9766. Checks for investment
must be in U.S. dollars drawn on a domestic bank. Credit card convenience checks
and third party checks, i.e., checks made payable to a party other than
Tri-Continental Corporation, may not be used to purchase shares under this Plan.
You should direct all


                                       17


correspondence concerning the Plan to Seligman Data Corp., 100 Park Avenue, New
York, NY 10017. At present, a service fee of up to a maximum of $2.00 will be
charged for each cash purchase transaction. There is no charge for Automatic
Dividend Investment. As of March 31, 2003, 29,653 stockholders, owning
approximately 47,762,639 shares of Common Stock, were using the Plan. You may
choose one or more of the services under the Plan and you may change your
choices (or terminate participation) at any time by notifying SDC in writing.
The Plan may be amended or terminated by written notice to Planholders.

Automatic Check Service

      The Automatic Check Service enables you, if you are an Automatic Dividend
Investment and Cash Purchase Planholder, to authorize checks to be drawn on your
regular checking account at regular intervals for fixed amounts to be invested
in additional shares of Common Stock for your account. An Authorization Form to
be used to start the Automatic Check Service is included in this Prospectus.

Share Keeping Service

      You may send certificates for shares of the Corporation's Common Stock to
SDC to be placed in your account. Certificates should be sent to Seligman Data

they be placed in your account. You should not sign the certificates and they
should be sent by certified or registered mail. Return receipt is advisable;
however, this may increase mailing time. When your certificates are received by
SDC, the shares will be entered in your Tri-Continental account as "book
credits" and shown on the Statement of Account received from SDC. If you use the
Share Keeping Service you should keep in mind that you must have a stock
certificate for delivery to a broker if you wish to sell shares. A certificate
will be issued and sent to you on your written request to SDC, usually within
two business days of the receipt of your request. You should consider the time
it takes for a letter to arrive at SDC and for a certificate to be delivered to
you by mail before you choose to use this service.

J. & W. Seligman & Co. Incorporated Matched Accumulation Plan

      The Manager has a Matched Accumulation Plan ("Profit-Sharing Plan") which
provides that, through payroll deductions which may be combined with matching
contributions and through any profit sharing


                                       18


distribution made by the Manager to the Profit-Sharing Plan, eligible employees
of the Manager, Seligman Advisors, Inc. and Seligman Services, Inc. may
designate that the payroll deductions and contributions made by the Manager and
invested by the Plan trustee, be invested in certain investment companies for
which the Manager serves as investment adviser. One such fund consists of Common
Stock of the Corporation purchased by the trustee as described under "Method of
Purchase."

Seligman Data Corp. Employees' Thrift Plan

      SDC has an Employees' Thrift Plan ("Thrift Plan") which provides a
systematic means by which savings, through payroll deductions, of eligible
employees of SDC may be combined with matching contributions made by the company
and invested by the Plan trustee, in certain investment companies for which the
Manager serves as investment adviser, as designated by the employee. One such
fund consists of Common Stock of the Corporation purchased by the trustee as
described under "Method of Purchase."

Method of Purchase

      Purchases will be made by the Corporation from time to time on the New
York Stock Exchange or elsewhere to satisfy dividend and cash purchase
investments under the Automatic Dividend Investment and Cash Purchase Plan,
tax-deferred retirement plans, and the investment plans noted above. Purchases
will be suspended on any day when the closing price (or closing bid price if
there were no sales) of the Common Stock on the New York Stock Exchange on the
preceding trading day was higher than the net asset value per share (without
adjustment for the exercise of Warrants remaining outstanding). If on the
dividend payable date or the date shares are issuable to stockholders making
Cash Purchase investments under the Plan (the "Issuance Date"), shares
previously purchased by the Corporation are insufficient to satisfy dividend or
Cash Purchase investments and on the last trading day immediately preceding the
dividend payable date or the Issuance Date the closing sale or bid price of the
Common Stock is lower than or the same as the net asset value per share, the
Corporation will continue to purchase shares until a number of shares sufficient
to cover all investments by stockholders has been purchased or the closing sale
or bid price of the Common Stock becomes higher than the net asset value, in
which case the Corporation will issue the necessary additional shares. If on the
last trading date immediately preceding the dividend payable date or Issuance
Date, the closing sale or bid price of the Common Stock was higher than the net
asset value per share, and if shares of the Common Stock previously purchased on
the New York Stock Exchange or elsewhere are insufficient to satisfy dividend or
Cash Purchase investments, the Corporation will issue the necessary additional
shares from authorized but unissued shares of the Common Stock.

      Shares will be issued on the dividend payable date or the Issuance Date at
a price equal to the lower of (1) the closing sale or bid price, plus
commission, of the Common Stock on the New York Stock Exchange on the
ex-dividend date or Issuance Date or (2) the greater of the net asset value per
share of the Common Stock on such trading day (without adjustment for the
exercise of Warrants remaining outstanding) and 95% of the closing sale or bid
price of the Common Stock on the New York Stock Exchange on such trading day. In
the past, the Common Stock ordinarily has been priced in the market at less than
net asset value per share.

      The net proceeds to the Corporation from the sale of any shares of Common
Stock to the Plans will be added to its general funds and will be available for
additional investments and general corporate purposes. The Manager anticipates
that investment of any proceeds, in accordance with the Corporation's investment
objective and policies, will take up to thirty days from their receipt by the
Corporation, depending on market conditions


                                       19


and the availability of appropriate securities, but in no event will such
investment take longer than six months. Pending such investment in accordance
with the Corporation's objective and policies, the proceeds will be held in U.S.
Government Securities (which term includes obligations of the United States
Government, its agencies or instrumentalities) and other short-term money market
instruments.

      If you are participating in the Automatic Dividend Investment and Cash
Purchase Plan and your shares are held under the Plan in book credit form, you
may terminate your participation in the Plan and receive a certificate for all
or a part of your shares or have all or a part of your shares sold for you by
the Corporation and retain unsold shares in book credit form or receive a
certificate for any shares not sold. Instructions must be signed by all
registered stockholders and should be sent to Seligman Data Corp., 101 Sabin
Street, Pawtucket, RI 02860-1427. If you elect to have shares sold, you will
receive the proceeds from the sale, less any brokerage commissions. Only
participants whose shares are held in book credit form may elect upon
termination of their participation in the Plan to have shares sold in the above
manner. All other stockholders of the Corporation must sell shares through a
registered broker/dealer. As an additional measure to protect you and the
Corporation, SDC may confirm written instructions by telephone before sending
your money when the value of the shares being sold is $25,000 or more, or when
proceeds are directed to be paid to an address or payee different from that on
our records. This will not affect the date on which your instruction to sell
shares is actually processed. Whenever the value of the shares being sold is
$50,000 or more, or the proceeds are to be paid or mailed to an address or payee
different from that on our records, the signature of all stockholders must be
guaranteed by an eligible financial institution including, but not limited to,
the following: banks, trust companies, credit unions, securities brokers and
dealers, savings and loan associations and participants in the Securities
Transfer Association Medallion Program ("STAMP"), the Stock Exchanges Medallion
Program ("SEMP") and the New York Stock Exchange Medallion Signature Program
("MSP"). Notarization by a notary public is not an acceptable signature
guarantee. The Corporation reserves the right to reject a signature guarantee
where it is believed that the Corporation will be placed at risk by accepting
such guarantee.

Systematic Withdrawal Plan

      This Plan is available if you wish to receive fixed payments from your
investment in the Common Stock in any amount at specified regular intervals. You
may start a Systematic Withdrawal Plan if your shares of the Corporation's
Common Stock have a market value of $5,000 or more. Shares must be held in your
account as book credits. SDC will act for you, make payments to you in specified
amounts on either the 1st or 15th day of each month, as designated by you, and
maintain your account. There is a charge by the agent of $1.00 per withdrawal
payment for this service. This charge may be changed from time to time.

      Payments under the Systematic Withdrawal Plan will be made by selling
exactly enough full and fractional shares of Common Stock to cover the amount of
the designated withdrawal. Sales may be made on the New York Stock Exchange, to
the agent or a trustee for one of the other Plans, or elsewhere. Payments from
sales of shares will reduce the amount of capital at work and dividend earning
ability, and ultimately may liquidate the investment. Sales of shares may result
in gain or loss for income tax purposes. Withdrawals under this Plan or any
similar withdrawal plan of any other investment company, concurrent with
purchases of shares of the Common Stock or of shares of any other investment
company, will ordinarily be disadvantageous to the Planholder because of the
payment of duplicative commission or sales loads.


                                       20

transactions to stockholders. To insure prompt delivery of checks, account
statements and other information, you should notify SDC immediately, in writing,

important that you notify SDC of any subsequent address changes to ensure that
you receive a year-end statement and tax information for that year. You will be

               ISSUANCE OF SHARES IN CONNECTION WITH ACQUISITIONS

      The Corporation may issue shares of its Common Stock in exchange for the
assets of another investment company in transactions in which the number of
shares of Common Stock of the Corporation to be delivered will be generally
determined by dividing the current value of the seller's assets by the current
per share net asset value or market price on the New York Stock Exchange of the
Common Stock of the Corporation, or by an intermediate amount. In such
acquisitions, the number of shares of the Corporation's Common Stock to be
issued will not be determined on the basis of the market price of such Common
Stock if such price is lower than its net asset value per share, except pursuant
to an appropriate order of the Securities and Exchange Commission or approval by
stockholders of the Corporation, as required by law. The Corporation is not
presently seeking to acquire the assets of any investment company, but it may
acquire the assets of companies from time to time in the future.

      Some or all of the stock so issued may be sold from time to time by the
recipients or their stockholders through brokers in ordinary transactions on
stock exchanges at current market prices. The Corporation has been advised that
such sellers may be deemed to be underwriters as that term is defined in the
1933 Act.

                              TERMS AND CONDITIONS

      The Automatic Dividend Investment and Cash Purchase Plan provides
Tri-Continental Common stockholders with four ways to add to their investments:
1) with Tri-Continental dividends and distributions, 2) with cash dividends from
other corporations, 3) with cash payments, in any amount at any time, and 4)
with cash provided by pre-authorized checks through the Automatic Check Service.
A Planholder may use any or all of these Services, subject to the following
terms and conditions:

      1. Seligman Data Corp. ("SDC"), as Plan service agent, will maintain
accounts and confirm to Planholders, as soon as practicable after each
investment, the number of shares of Common Stock acquired and credited to the
accounts and the cost. Tri-Continental Corporation (the "Corporation"), as
purchase agent, will purchase shares for Planholders. All checks for dividends
payable by other corporations or for cash purchase payments sent by Planholders
for investment in additional shares of Tri-Continental Common Stock should be
drawn to the order of Tri-Continental Corporation and mailed to Seligman Data
Corp., P.O. Box 9766, Providence, Rhode Island 02940-9766.

      2. Funds received by the Corporation for a Planholder will be combined
with funds of other Planholders and those funds may be combined with funds
available under the other Plans for the purchase of Tri-Continental Common Stock
in order to minimize brokerage commissions on shares purchased. Shares will be
purchased in accordance with the current Prospectus. Dividends from other
corporations and purchase cash received from Planholders or through the
Automatic Check Service will be invested at least once each 30 days.

      3. Shares will be issued under the Plan in accordance with the current
Prospectus.

      4. No stock certificates will be delivered for shares acquired unless the
Plan account is terminated or the Planholder requests their delivery by writing
to SDC. The shares acquired will be held in each Planholder's account as book
credits.

      5. Certificates held by a Planholder, or subsequently received, may be
sent to SDC for credit to a Plan account. A certificate for any full shares held
in a Plan account will be issued at a Planholder's request. The time required to
obtain a certificate to sell through a broker, or for other purposes, will be
that needed to send a written request to SDC to withdraw the certificate
(normally two business days) and to mail the certificate to the Planholder
through the U.S. Postal Service.

      6. A maximum service charge of $2.00 will be deducted before each
investment is made for a Plan account. There is no charge for Automatic Dividend
Investment.

      7. Applications for the Automatic Check Service are subject to acceptance
by the Planholder's bank and SDC. SDC will prepare Automatic Check Service
checks with the same magnetic ink numbers that are on a Planholder's check and
will arrange with the Planholder's bank to start the Service in accordance with
the Planholder's instructions. A minimum of 30 days from the date of receipt of
an application by SDC is required to contact the bank and initiate the Service.
If for any reason the bank is unable to honor a pre-authorized check request,
the Planholder will be notified promptly.

      Shares with a market value of at least two times the amount of the
authorized checks must be held as book credits for the Planholder's account by
SDC. If any check is dishonored or if the value of shares held by SDC in an
account falls below the required minimum, the Service may be suspended. The
Service may be reinstated upon written request by the Planholder including an
indication that the cause of the interruption has been corrected.

      If a Planholder's check is not honored by the Planholder's bank at any
time, SDC is authorized to sell exactly enough full and fractional shares from
the Planholder's account to equal the amount of the dishonored check.

      8. A Planholder or SDC may terminate a Plan account at any time upon
notice in writing before the record date of a dividend or distribution by
Tri-Continental. A Plan account will terminate automatically if the Planholder
sells or transfers all of the shares in the Plan account. If a Plan account is
terminated, a certificate for the full shares held may be issued and sent to the
Planholder, and any fractional shares may be liquidated at the Planholder's
request. Terminating Planholders may elect to have all or part of their shares
sold by the Corporation, if their shares are held in book credit form. If a Plan
account is terminated between the record and payment dates of a dividend, the
dividend payment will be made in cash.

      9. In acting under this Plan, the Corporation and SDC will be liable only
for willful misfeasance or gross negligence.

      10. A Planholder may adopt or suspend one or more of the Plan Services by
sending a revised Authorization Form or notice in writing to SDC.

      11. All additional shares registered in a Planholder's name which are
acquired under one or more of the Plan Services or by other means will
participate automatically in each of the Plan services elected.

                         ADDITIONAL INVESTMENT POLICIES

The investment objectives and policies of the Corporation are set forth in the
Prospectus. Certain additional investment information is set forth below.
Defined terms used herein and not otherwise defined shall have the meanings
ascribed to them in the Prospectus.

Fundamental Policies

The Corporation's stated fundamental policies, which may not be changed without
a vote of stockholders are listed below; within the limits of these fundamental
policies, the management has reserved freedom of action. The Corporation:

(1)   may issue senior securities such as bonds, notes or other evidences of
      indebtedness if immediately after issuance the net assets of the
      Corporation provide 300% coverage of the aggregate principal amount of all
      bonds, notes or other evidences of indebtedness and that amount does not
      exceed 150% of the capital and surplus of the Corporation;

(2)   may issue senior equity securities on a parity with, but not having
      preference or priority over, the Preferred Stock if immediately after
      issuance its net assets are equal to at least 200% of the aggregate amount
      (exclusive of any dividends accrued or in arrears) to which all shares of
      the Preferred Stock, then outstanding, shall be entitled as a preference
      over the Common Stock in the event of voluntary or involuntary
      liquidation, dissolution or winding up of the Corporation;

(3)   may borrow money for substantially the same purposes as it may issue
      senior debt securities, subject to the same restrictions and to any
      applicable limitations prescribed by law;

(4)   may engage in the business of underwriting securities either directly or
      through majority-owned subsidiaries subject to any applicable restrictions
      and limitations prescribed by law;

(5)   does not intend to concentrate its assets in any one industry although it
      may from time to time invest up to 25% of the value of its assets, taken
      at market value, in a single industry;

(6)   may not, with limited exceptions, purchase and sell real estate directly
      but may do so through majority-owned subsidiaries, so long as its real
      estate investments do not exceed 10% of the value of the Corporation's
      total assets;

(7)   may not purchase or sell commodities or commodity contracts; and

(8)   may make money loans (subject to restrictions imposed by law and by
      charter) (a) only to its subsidiaries, (b) as incidents to its business
      transactions or (c) for other purposes. It may lend its portfolio
      securities to brokers or dealers in corporate or government securities,
      banks or other recognized institutional borrowers of securities subject to
      any applicable requirements of a national securities exchange or of a
      governmental regulatory body against collateral consisting of cash or
      direct obligations of the United States, maintained on a current basis, so
      long as all such loans do not exceed 10% of the value of total assets, and
      it may make loans represented by repurchase agreements, as described in
      the Prospectus, so long as such loans do not exceed 10% of the value of
      total assets.

During its last three fiscal years, the Corporation did not: (a) issue senior
securities; (b) borrow any money; (c) underwrite securities; (d) concentrate
investments in particular industries or groups of industries; (e) purchase or
sell real estate, commodities, or commodity contracts; or (f) make money loans
or lend portfolio securities.

Other Policies

Leverage. When securities are loaned, the Corporation receives from the borrower
the equivalent of dividends or interest paid by the issuer of securities on loan
and, at the same time, makes short-term investments with the cash collateral and
retains the interest earned, after payment to the borrower or placing broker of
a negotiated portion of such interest, or receives from the borrower an agreed
upon rate of interest in the case of loans collateralized by direct obligations
of the United States. The Corporation does not have the right to vote securities
on loan, but would expect to terminate the loan and regain the right to vote if
that were considered important with respect to the investment.


                                       2


Foreign Securities. In order to take advantage of opportunities that may be
provided by debt instruments of foreign issuers, the Corporation may from time
to time invest up to 3% of its assets in debt securities issued or guaranteed by
a foreign government or any of its political subdivisions, authorities, agencies
or instrumentalities and in related forward contracts. The Manager will
determine the percentage of assets invested in securities of a particular
country or denominated in a particular currency in accordance with its
assessment of the relative yield and appreciation potential of such securities
and the relationship of a country's currency to the U.S. dollar. Currently, the
Corporation will invest in securities denominated in foreign currencies or U.S.
dollars of issuers located in the following countries: Australia, Austria,
Belgium, Canada, Denmark, France, Germany, Hong Kong, Italy, Japan, Malaysia,
Mexico, the Netherlands, New Zealand, Norway, Singapore, Spain, Sweden,
Switzerland, Thailand and the United Kingdom. An issuer of debt securities
purchased by the Corporation may be domiciled in a country other than the
country in whose currency the instrument is denominated.

The Corporation's returns on foreign currency denominated debt instruments can
be adversely affected by changes in the relationship between the U.S. dollar and
foreign currencies. The Corporation may engage in currency exchange transactions
to protect against uncertainty in the level of future exchange rates in
connection with hedging and other non-speculative strategies involving specific
settlement transactions or portfolio positions. The Corporation will conduct its
currency exchange transactions either on a spot (i.e., cash) basis at the rate
prevailing in the currency market or through forward contracts.

Rights and Warrants. The Corporation may not invest in rights and warrants if,
at the time of acquisition, the investment in rights and warrants would exceed
5% of the Corporation's net assets, valued at the lower of cost or market. In
addition, no more than 2% of net assets may be invested in warrants not listed
on the New York or American Stock Exchanges. For purposes of this restriction,
warrants acquired by the Corporation in units or attached to securities may be
deemed to have been purchased without cost.

Forward Foreign Currency Exchange Contracts. A forward foreign currency exchange
contract is an agreement to purchase or sell a specific currency at a future
date and at a price set at the time the contract is entered into. The
Corporation will generally enter into forward foreign currency exchange
contracts to fix the U.S. dollar value of a security it has agreed to buy or
sell for the period between the date the trade was entered into and the date the
security is delivered and paid for, or, to hedge the U.S. dollar value of
securities it owns.

The Corporation may enter into a forward contract to sell or buy the amount of a
foreign currency it believes may experience a substantial movement against the
U.S. dollar. In this case the contract would approximate the value of some or
all of the Corporation's portfolio securities denominated in such foreign
currency. Under normal circumstances, the portfolio manager will limit forward
currency contracts to not greater than 75% of the Corporation's portfolio
position in any one country as of the date the contract is entered into. This
limitation will be measured at the point the hedging transaction is entered into
by the Corporation. Under extraordinary circumstances, the Manager may enter
into forward currency contracts in excess of 75% of the Corporation's portfolio
position in any one country as of the date the contract is entered into. The
precise matching of the forward contract amounts and the value of securities
involved will not generally be possible since the future value of such
securities in foreign currencies will change as a consequence of market
involvement in the value of those securities between the date the forward
contract is entered into and the date it matures. The projection of short-term
currency market movement is extremely difficult, and the successful execution of
a short-term hedging strategy is highly uncertain. Under certain circumstances,
the Corporation may commit up to the entire value of its assets which are
denominated in foreign currencies to the consummation of these contracts. The
Manager will consider the effect a substantial commitment of its assets to
forward contracts would have on the investment program of the Corporation and
its ability to purchase additional securities.

Except as set forth above and immediately below, the Corporation will also not
enter into such forward contracts or maintain a net exposure to such contracts
where the consummation of the contracts would oblige the Corporation to deliver
an amount of foreign currency in excess of the value of the Corporation's
portfolio securities or other assets denominated in that currency. The
Corporation, in order to avoid excess transactions and transaction costs, may
nonetheless maintain a net exposure to forward contracts in excess of the value
of the Corporation's portfolio securities or other assets denominated in that
currency provided the excess amount is "covered" by cash or liquid, high-grade
debt securities, denominated in any currency, at least equal at all times to the
amount of such excess. Under normal circumstances, consideration of the prospect
for currency parties will be incorporated into the longer-term investment
decisions made with regard to overall diversification strategies. However, the
Manager believes that it is important to have the flexibility to enter into such
forward contracts when it determines that the best interests of the Corporation
will be served.


                                       3


At the maturity of a forward contract, the Corporation may either sell the
portfolio security and make delivery of the foreign currency, or it may retain
the security and terminate its contractual obligation to deliver the foreign
currency by purchasing an "offsetting" contract obligating it to purchase, on
the same maturity date, the same amount of the foreign currency.

As indicated above, it is impossible to forecast with absolute precision the
market value of portfolio securities at the expiration of the forward contract.
Accordingly, it may be necessary for the Corporation to purchase additional
foreign currency on the spot market (and bear the expense of such purchase) if
the market value of the security is less than the amount of foreign currency the
Corporation is obligated to deliver and if a decision is made to sell the
security and make delivery of the foreign currency. Conversely, it may be
necessary to sell on the spot market some of the foreign currency received upon
the sale of the portfolio security if its market value exceeds the amount of
foreign currency the Corporation is obligated to deliver. However, the
Corporation may use liquid, high-grade debt securities, denominated in any
currency, to cover the amount by which the value of a forward contract exceeds
the value of the securities to which it relates.

If the Corporation retains the portfolio security and engages in offsetting
transactions, the Corporation will incur a gain or a loss (as described below)
to the extent that there has been movement in forward contract prices. If the
Corporation engages in an offsetting transaction, it may subsequently enter into
a new forward contract to sell the foreign currency. Should forward prices
decline during the period between the Corporation's entering into a forward
contract for the sale of a foreign currency and the date it enters into an
offsetting contract for the purchase of the foreign currency, the Corporation
will realize a gain to the extent the price of the currency it has agreed to
sell exceeds the price of the currency it has agreed to purchase. Should forward
prices increase, the Corporation will suffer a loss to the extent the price of
the currency it has agreed to purchase exceeds the price of the currency it has
agreed to sell.

The Corporation's dealing in forward foreign currency exchange contracts will be
limited to the transactions described above. Of course, the Corporation is not
required to enter into forward contracts with regard to its foreign
currency-denominated securities and will not do so unless deemed appropriate by
the Manager. It also should be realized that this method of hedging against a
decline in the value of a currency does not eliminate fluctuations in the
underlying prices of the securities. It simply establishes a rate of exchange at
a future date. Additionally, although such contracts tend to minimize the risk
of loss due to a decline in the value of a hedged currency, at the same time,
they tend to limit any potential gain which might result from an increase in the
value of that currency.

Stockholders should be aware of the costs of currency conversion. Although
foreign exchange dealers do not charge a fee for conversion, they do realize a
profit based on the difference (the "spread") between the prices at which they
are buying and selling various currencies. Thus, a dealer may offer to sell a
foreign currency to the Corporation at one rate, while offering a lesser rate of
exchange should the Corporation desire to resell that currency to the dealer.

Investment income received by the Corporation from sources within foreign
countries may be subject to foreign income taxes withheld at the source. The
United States has entered into tax treaties with many foreign countries which
entitle the Corporation to a reduced rate of such taxes or exemption from taxes
on such income. It is impossible to determine the effective rate of foreign tax
in advance since the amounts of the Corporation's assets to be invested within
various countries is not known.

Portfolio Turnover

The Corporation's portfolio turnover rate for the years ended December 31, 2002
and 2001 were 152.79% and 124.34%, respectively.

No compensation is paid by the Corporation to Directors or officers of the

directors may elect to defer receiving their fees. A director who has elected
deferral of his or her fees may choose a rate of return equal to either (1) the
interest rate on short-term Treasury Bills, or (2) the rate of return on the
shares of certain of the investment companies advised by the Manager, as
designated by the director. The annual cost of such fees and interest is
included in the director's fees and expenses and the accumulated balance thereof
is included in "Liabilities" in the Corporation's financial statements.

As of December 31, 2002, the total amount of deferred compensation (including
interest) payable in respect of the Corporation to Mr. Whitson was $171,009. Mr.
Merow no longer defers current compensation; however, he has accrued deferred
compensation in the amount of $54,265, as of December 31, 2002.

Directors and officers of the Corporation are also directors, trustees and
officers of some or all of the other investment companies in the Seligman Group
of Funds.


                                       8


Code of Ethics

The Manager, Seligman Advisors, Inc. (Seligman Advisors), their subsidiaries and
affiliates, and the Seligman Group of Funds have adopted a Code of Ethics that
sets forth the circumstances under which officers, directors and employees
(collectively, Employees) are permitted to engage in personal securities
transactions. The Code of Ethics proscribes certain practices with regard to
personal securities transactions and personal dealings, provides a framework for
the reporting and monitoring of personal securities transactions by the
Manager's Director of Compliance, and sets forth a procedure of identifying, for
disciplinary action, those individuals who violate the Code of Ethics. The Code
of Ethics prohibits Employees (including all investment team members) from
purchasing or selling any security or an equivalent security that is being
purchased or sold by any client, or where the Employee intends, or knows of
another's intention, to purchase or sell a security on behalf of a client. The
Code also prohibits all Employees from acquiring securities in a private
placement or in an initial or secondary public offering unless an exemption has
been obtained from the Manager's Director of Compliance.

The Code of Ethics prohibits (1) each portfolio manager or member of an
investment team from purchasing or selling any security within seven calendar
days either before or after the purchase or sale of the security by a client's
account (including investment company accounts) that the portfolio manager or
investment team manages; (2) each Employee from profiting from short-term
trading (a profitable purchase and sale or vice-versa within 60 days); and (3)
each member of an investment team from profiting from short sales of a security
if, at that time, any client managed by that team has a long position in that
security. Any profit realized pursuant to any of these prohibitions must be
disgorged to charitable organizations.

Employees are required, except under very limited circumstances, to engage in
personal securities transactions through the Manager's order desk, or through an
authorized dealer or investment advisor designated by the Manager. All Employee
personal securities transactions must be pre-cleared through the Manager's
compliance department. The compliance department and the order desk maintain a
list of securities that may not be purchased due to a possible conflict with
clients. All Employees are also required to disclose all securities beneficially
owned by them upon commencement of employment and at the end of each calendar
year.

A copy of the Code of Ethics is on public file with, and is available upon
request from, the SEC. You can access it through the SEC's Internet site,
www.sec.gov.

                          MANAGEMENT OF THE CORPORATION

The Manager

J. & W. Seligman & Co. Incorporated (the "Manager"), subject to the control of
the Corporation's Board of Directors, manages the investments of the assets of
the Corporation and administers its business and other affairs pursuant to a
management agreement (the "Management Agreement"). The Manager also serves as
investment manager to twenty-one other US registered investment companies which,
together with the Corporation, make up the "Seligman Group of Funds." There are
no other management-related service contracts under which services are provided
to the Corporation. No person or persons, other than the Directors, officers or
employees of the Manager and the Corporation regularly advise the Corporation
with respect to its investments.

The Manager is a successor firm to an investment banking business founded in
1864 which has provided investment services to individuals, families,
institutions and corporations. Mr. William C. Morris, Chairman of the Manager
and Chairman of the Board of Directors and Chairman of the Corporation, owns a
majority of the outstanding voting securities of the Manager and is a
controlling person of the Manager. See the Appendix to this SAI for information
regarding the history of the Manager.

The Corporation pays the Manager a management fee for its services, calculated
daily and payable monthly, equal to a percentage of the daily net assets of the
Corporation. The method for determining this percentage, referred to as the
management fee rate, is set forth in the Prospectus. The management fee amounted
to $9,895,235 in 2002, $12,508,900 in 2001 and $15,398,779 in 2000,
respectively, which was equivalent to an annual rate of 0.41%, 0.40% and 0.39%,
respectively, of the average daily net assets of the Corporation.

As part of its services to the Corporation, the Manager provides the Corporation
with such office space, administrative and other services and executive and
other personnel as are necessary for the operations of the Corporation. The
Manager also provides senior management for Seligman Data Corp., a wholly-owned
subsidiary


                                       9


of the Corporation and certain of the other investment companies in the Seligman
Group of Funds. The Manager pays all of the compensation of the Directors of the
Corporation who are employees or consultants of the Manager and its affiliates,
of the officers and employees of the Corporation and of certain executive
officers of Seligman Data Corp.

At the November 21, 2002 Board of Directors meeting, the Board unanimously
approved the continuance of the Management Agreement. In preparation for the
meeting, the Board requested and reviewed a wide variety of materials from the
Manager, including extensive performance and expense information for other
investment companies compiled by third parties, and the Independent Directors
conferred with their counsel at the meeting prior to voting. In their
determinations with respect to continuance of the Management Agreement, the
Board considered many factors, including, but not limited to: (1) the investment
results achieved by the Manager for the Corporation (including investment
performance comparisons with other comparable closed-end funds and certain
indices); (2) the nature and quality of the administrative services rendered by
the Manager; (3) the payments received by the Manager and its affiliates from
all sources involving both the Corporation and the other investment companies in
the Seligman Group of Funds; (4) the costs borne by, and profitability of, the
Manager and its affiliates in providing service of all types to the Corporation
and to the other investment companies in the Seligman Group of Funds; (5)
information concerning the Corporation's expense ratio and competitive industry
fee structures and expense ratios, including, specifically, the relationship of
the Corporation's management fee rates to those typically paid by similar funds;
(6) the Manager's policies and practices regarding allocation of portfolio
transactions, including the use of brokers or dealers that provided research and
other services to the Manager and the benefits derived from such services to the
Corporation and to the Manager; (7) portfolio turnover for the Corporation and
other comparable investment companies; (8) the Manager's willingness to consider
and, when desirable, implement organizational and operational changes designed
to improve investment results; and (9) the fall-out benefits which the Manager
and its affiliates receive from the Manager's relationship to the Corporation.
In its deliberations, the Board did not identify any particular information that
was all-important or controlling. Rather, the Board evaluated all information
available to it and determined that the compensation paid to the Manager under
the Management Agreement was fair and reasonable in light of the services
performed, expenses incurred and such other matters as the Board (and each
Director) considered relevant in the exercise of its (or such Director's)
reasonable judgment.

Certain of the factors addressed by the Board in reaching its determination are
discussed in more detail below.

Portfolio Performance. The Board of Directors considered the performance of the
Corporation as compared to the performance of other comparable closed-end funds
and as compared to appropriate securities indices. Directors also considered the
nature and quality of the investment advice rendered by the Manager. In addition
to the information received by the Directors in connection with the November 21,
2002 Board of Directors meeting, the Board receives detailed information related
to performance of the Corporation at each Board meeting during the year.

Expenses of the Corporation. The Board also considered the management fee rate
paid by the Corporation to the Manager and the other expenses of the
Corporation, in comparison to both the quality of services provided and the fees
and expenses of funds with similar characteristics.

Costs of Providing Service and Profitability. The Directors reviewed information
concerning profitability of the Manager's investment advisory and investment
company activities and its financial condition based on results for 2001 and
2002 (through September 30) and estimates for full-year 2002. The information
considered by the Board of Directors included operating profit margin
information for the Manager's investment company business alone (i.e., excluding
results of its affiliates) and on a consolidated basis. The Board of Directors
also reviewed profitability data and estimated profitability data for each of
the investment companies of the Seligman Group of Funds on a fund-by-fund basis.
The Board of Directors reviewed certain assumptions and methods of allocation
used by the Manager in preparing fund-specific profitability data. While the
Manager believes that the methods of allocation used were reasonable, there are
limitations inherent in allocating costs to multiple individual advisory
products served by an organization such as the Manager's where each of the
advisory products draws on, and benefits from, the pooled research of the
organization.


                                       10


             HOLDINGS OF PREFERRED STOCK, COMMON STOCK AND WARRANTS

As of March 31, 2003, holders of record of Preferred Stock totaled 394; holders
of record of Common Stock totaled 36,296; and holders of record of Warrants
totaled 104.

Control Persons

As of March 31, 2003, there was no person or persons who controlled the
Corporation, either through a significant ownership of shares or any other means
of control.

Principal Holders

As of March 31, 2003, the principal holders of 5% or more of the outstanding
equity securities of the Corporation, are: (1) Cede & Co., a nominee for The
Depository Trust Company, 55 Water Street, New York, New York 10041, owns of
record approximately 42% of the Corporation's Common Stock outstanding;
approximately 81% of the Corporation's Preferred Stock outstanding and
approximately 58% of the Corporation's Warrants outstanding; and (2) Dwight
Goldthorpe, PO Box 2778, Palm Beach, Florida 33480, owns of record approximately
12% of the Corporations Warrants outstanding.

Management Ownership

As of March 31, 2003, all Directors and officers of the Corporation, as a group,
owned less than 1% of the Corporation's Common Stock. As of the same date, no
Directors or officers owned any of the Corporation's Preferred Stock or
Warrants.

                    BROKERAGE ALLOCATION AND OTHER PRACTICES

Brokerage Transactions. The Management Agreement recognizes that in the purchase
and sale of portfolio securities of the Corporation, the Manager will seek the
most favorable price and execution, and, consistent with that policy, may give
consideration to the research, statistical and other services furnished by
brokers or dealers to the Manager for its use, as well as to the general
attitude toward and support of investment companies demonstrated by such brokers
or dealers. Such services include supplemental investment research, analysis and
reports concerning issuers, industries and securities deemed by the Manager to
be beneficial to the Corporation. In addition, the Manager is authorized to
place orders with brokers who provide supplemental investment and market
research and security and economic analysis although the use of such brokers may
result in a higher brokerage charge to the Corporation than the use of brokers
selected solely on the basis of seeking the most favorable price and execution
and although such research and analysis may be useful to the Manager in
connection with its services to clients other than the Corporation.

In over-the-counter markets, the Corporation deals with primary market makers
unless a more favorable execution or price is believed to be obtainable. The
Corporation may buy securities from or sell securities to dealers acting as
principal, except dealers with which its directors and/or officers are
affiliated.

When two or more of the investment companies of the Seligman Group of Funds or
other investment advisory clients of the Manager desire to buy or sell the same
security at the same time, the securities purchased or sold are allocated by the
Manager in a manner believed to be equitable to each. There may be possible
advantages or disadvantages of such transactions with respect to price or the
size of positions readily obtainable or saleable.

Commissions. Total brokerage commissions (not including any spreads on principal
transactions on a net basis) paid by the Corporation during the years ended
December 31, 2002, 2001 and 2000, were $8,675,607, $8,798,853 and $4,830,427,
respectively.

Regular Broker-Dealers. During the year ended December 31, 2002, the Corporation
acquired securities of its regular brokers or dealers (as defined in Rule 10b-1
under the 1940 Act) or of their parents. The Corporation held securities of
Citigroup, Inc., the parent company of Salomon Smith Barney, with an aggregate
value of $61,277,403; held securities of Morgan Stanley Dean Witter, with an
aggregate value of $9,545,872; and held securities of Merrill Lynch & Co.

                 HISTORY OF J. & W. SELIGMAN & CO. INCORPORATED

Seligman's beginnings date back to 1837, when Joseph Seligman, the oldest of
eight brothers, arrived in the United States from Germany. He earned his living
as a pack peddler in Pennsylvania, and began sending for his brothers. The
Seligmans became successful merchants, establishing businesses in the South and
East.

Backed by nearly thirty years of business success - culminating in the sale of
government securities to help finance the Civil War - Joseph Seligman, with his
brothers, established the international banking and investment firm of J. & W.
Seligman & Co. In the years that followed, the Seligman Complex played a major
role in the geographical expansion and industrial development of the United
States.
