                               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  repurchase  agreements,   options,   illiquid
securities  and  securities  of foreign  issuers,  each of which  could  involve
certain risks. See "Investment and Other Policies."


     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  seventeen  other U.S.  registered  investment
companies which,  together with the Corporation,  make up the "Seligman  Group."
The aggregate assets of the Seligman Group at March 31, 1999 were  approximately
$21.1  billion.  The Manager also  provides  investment  management or advice to
institutional   and  other  accounts  having  a  value  at  March  31,  1999  of
approximately  $9.6  billion.  The Manager's fee is based in part on the average
daily  net  assets  of the  Corporation.  The  management  fee rate for 1998 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 "Description
of Investment Plans and Other  Services--Automatic  Dividend Investment and Cash
Purchase Plan" and "--Systematic  Withdrawal Plan." 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 19, 1998, the Board of Directors  authorized the Corporation to
repurchase  over a  12-month  period up to 7.5% of its then  outstanding  Common
Stock. 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 the marketplace.
Shares  acquired  by  the  Corporation  from   participants  in  the  Systematic
Withdrawal  Plan and  other  stockholder  plans  are  counted  towards  the 7.5%
repurchase limit under the program.  As of March 31, 1999,  1,794,095 shares, or
approximately  1.62% of the shares  outstanding  on November 19, 1998,  had been
repurchased under the program.

     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


                                       3

management  investment company of the closed-end type. The Corporation's  Common
Stock is listed  on the New York  Stock  Exchange  under  the  symbol  "TY." The
average  weekly  trading  volume on that and  other  exchanges  during  1998 was
277,681 shares.  The Corporation's  Common Stock has historically been traded on
the market at less than net asset value.  As of March 31, 1999, the  Corporation
had 116,590,051  shares of Common Stock outstanding and net assets  attributable
to Common Stock of $4,057,377,003.

                              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  1998  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 AND OTHER POLICIES



     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,
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, 1998 are shown under "Financial Highlights."


The  foregoing  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, the 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 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


                                      9
<PAGE>

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.  The  Corporation  did not enter into
repurchase agreements in 1998.


     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 of the  Corporation's  Common  Stock or the  income
available to it to increase more than otherwise  would be the case.  Conversely,


                                       10
<PAGE>

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, 1999,  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, 1999 asset value, the Corporation's
portfolio requires an annual return of 0.05% 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.


<TABLE>

     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.



     YEAR 2000: As the millennium  approaches,  investment companies,  financial
and business organizations, and individuals could be adversely affected if their
computer systems do not properly process and calculate date-related  information
and data on and after  January 1, 2000.  Like other  investment  companies,  the
Corporation  relies upon service  providers and their  computer  systems for its
day-to-day  operations.  Many of the  Corporation's  service  providers  in turn
depend  upon  computer  systems  of  their  vendors.  The  Manager  and SDC have
established a year 2000 project team.  The team's purpose is to assess the state
of  readiness  of the  Manager  and  SDC  and the  Corporation's  other  service
providers and vendors.  The team is comprised of several information  technology
and business  professionals as well as outside consultants.  The Project Manager
of the team reports directly to the Administrative Committee of the Manager. The
Project  Manager  and  other  members  of the team  also  report to the Board of
Directors of the Corporation and its Audit Committee.



     The team has  identified  the  service  providers  and  vendors who furnish
critical services or software systems to the Corporation,  including  securities
firms  that  execute  portfolio  transactions  for  the  Corporation  and  firms
responsible  for  shareholder  account  recordkeeping.  The team is working with
these  critical  service  providers and vendors to evaluate the impact year 2000
issues  may have on their  ability  to  provide  uninterrupted  services  to the
Corporation.  The team will assess the feasibility of their year 2000 plans. The
team has made progress on its year 2000  contingency  plans -- recovery  efforts
the team will  employ in the event that year 2000  issues  adversely  affect the
Corporation. The team anticipates finalizing these plans in the near future.



     The  Corporation  anticipates  the  team  will  implement  all  significant
components  of the team's  year 2000 plans by  mid-1999,  including  appropriate
testing of critical systems and receipt of satisfactory assurances from critical
service  providers  and  vendors  regarding  their  year  2000  compliance.  The
Corporation  believes that the critical systems on which it relies will function
properly  on and  after  the year  2000,  but this is not  guaranteed.  If these
systems  do  not  function  properly,  or  the  Corporation's  critical  service
providers  are not  successful  in  implementing  their  year  2000  plans,  the
Corporation's   operations  may  be  adversely   affected,   including  pricing,
securities trading and settlement, and the provision of shareholder services.



     In  addition,   the  Corporation  may  hold  securities  of  issuers  whose
underlying business leaves them susceptible to year 2000 issues. The Corporation
may also hold securities issued by governmental or quasi- governmental issuers,


                                       11
<PAGE>

which,  like other  organizations,  are also  susceptible to year 2000 concerns.
Year 2000  issues  may  affect an  issuer's  operations,  creditworthiness,  and
ability to make  timely  payment on any  indebtedness  and could have an adverse
impact  on  the  value  of  its  securities.  If  the  Corporation  holds  these
securities,  the  Corporation's  performance could be negatively  affected.  The
Manager  seeks to identify an issuer's  state of year 2000  readiness as part of
the  research it  employs.  However,  the  perception  of an issuer's  year 2000
preparedness is only one of the many factors  considered in determining  whether
to buy,  sell, or continue to hold a security.  Information  provided by issuers
concerning  their  state of  readiness  may or may not be  accurate  or  readily
available. Further, the Corporation may be adversely affected if the domestic or
foreign exchanges, markets, depositories, clearing agencies, or government(s) or
third parties  responsible  for  infrastructure  needs do not address their year
2000 issues in a satisfactory manner.


     SDC has  informed the  Corporation  that it does not expect the cost of its
services to increase materially as a result of the modifications to its computer
systems  necessary to prepare for the year 2000. The Corporation will not pay to
remediate  the systems of Seligman or bear  directly the costs to remediate  the
systems of any other service providers or vendors, other than SDC.


                         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 objectives and policies.


     The  Manager  also  serves as manager of  seventeen  other U.S.  registered
investment companies which, together with the Corporation, make up the "Seligman
Group." 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  Henderson Global Fund Series,  Inc.,  Seligman High Income Fund
Series,  Seligman Income Fund, Inc.,  Seligman  Municipal Fund Series,  Inc. and
Seligman  Municipal  Series Trust,  Seligman New Jersey  Municipal  Fund,  Inc.,
Seligman Pennsylvania Municipal Fund Series, Seligman Portfolios, Inc., Seligman
Quality Municipal Fund, Inc., Seligman Select Municipal Fund, 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:

                         .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.


                                       12
<PAGE>


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).


     Charles C. Smith, Jr., a Managing Director of the Manager has been
Portfolio Manager for the Corporation since January 1, 1995. Mr. Smith is also
Vice President and Portfolio Manager of Seligman Common Stock Fund, Inc. and
Seligman Income Fund, Inc., and Vice President of Seligman Portfolios, Inc.
("SPI") and Portfolio Manager of SPI's Seligman Common Stock Portfolio and
Seligman Income Portfolio. Mr. Smith joined the Manager in 1985 as a Vice
President, Investment Officer and was promoted to Senior Vice President, Senior
Investment Officer in August 1992, and to Managing Director in January 1994.



     Rodney D.  Collins,  a Senior  Vice  President,  Investment  Officer of the
Manager,  has served as Co-Portfolio Manager of the Corporation since July 1998.
Mr. Collins is also  Co-Portfolio  Manager of Seligman Common Stock Fund,  Inc.,
Seligman  Income Fund,  Inc., and the Seligman  Common Stock and Seligman Income
Portfolios  of SPI.  Mr.  Collins  joined the  Manager in 1992 as an  investment
associate and was promoted to a Vice  President,  Investment  Officer in January
1995, and to Senior Vice President, Investment Officer in January 1999.


     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 $.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


                                       13
<PAGE>

dividends  declared on the Preferred Stock,  shall be at least equal to $100 per
outstanding  share of Preferred  Stock.  The equivalent  figure was $5,044.14 at
March 31, 1999.

     (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  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 

                                      14
<PAGE>

redemption, the terms on conversion, and 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 $22.50 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  17.85  shares of Common  Stock at $1.26 per share.  There were  13,811
Warrants  outstanding at March 31, 1999.  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 at current market value.  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.

     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,

                                       15
<PAGE>

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.  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.

     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.

                                       16
<PAGE>

     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 their own tax advisers  regarding  specific  questions as to federal,
state or local taxes.



     THE CORPORATION IS REQUIRED TO WITHHOLD AND REMIT TO THE U.S.  TREASURY 31%
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

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
Corp., 4400 Computer Drive, Westborough, MA 01581-5120, with a letter requesting
that 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.


TAX-DEFERRED RETIREMENT PLANS

     Shares of the Corporation may be purchased for:

        -- Individual Retirement Accounts (IRAs) (available to current
           stockholders only);

        -- Savings Incentive Match Plans for Employees (SIMPLE IRAs);

        -- Money   Purchase   Pension   and  Profit   Sharing   Plans  for  sole
           proprietorships, partnerships and corporations.

     These  types of plans may be  established  only upon  receipt  of a written
application  form. The  Corporation  may register an IRA investment for which an
account application has not been received as on ordinary taxable account.

     Investors  Fiduciary  Trust Company  ("IFTC") acts as trustee and custodian
and performs other related services with respect to the Plans.

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 distribution made by the Manager to
the Profit-Sharing  Plan, eligible employees of the Manager,  Seligman Advisors,
Inc. (formerly,  Seligman Financial Services,  Inc.) and Seligman Services, Inc.


                                      18
<PAGE>

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 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 objectives and


                                       19
<PAGE>

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., 4400 Computer
Drive,  Westborough,  MA  01581-5120.  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. 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 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.

STOCKHOLDER INFORMATION


     SDC  maintains  books  and  records  for  all of the  Plans,  and  confirms
transactions  to  Stockholders.  To insure  prompt  delivery of checks,  account
statements and other information, you should notify SDC immediately, in writing,
of any  address  changes.  If you  close  your  account  during  any  year it is
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
sent reports quarterly regarding the Corporation.  General information about the
Corporation  may be requested by writing the  Corporate  Communications/Investor
Relations Department, J. & W. Seligman & Co. Incorporated,  100 Park Avenue, New

               ISSUANCE OF SHARES IN CONNECTION WITH ACQUISITIONS

     The  Corporation  may issue  shares of its Common Stock in exchange for the
assets of  another  investing  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  investing  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.

                             ADDITIONAL INFORMATION

     During 1998, the  Corporation  had  transactions  in the ordinary course of
business  with firms and  companies of which one or more  directors and officers
was a director  and/or officer of the  Corporation,  and it is expected that the
Corporation will continue to have transactions of such nature during the current
year.

                              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 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. The cost of  shares  acquired  for each Plan  will be the  average  cost,
including  brokerage  commissions  and any other  costs of  acquisition,  of all
shares acquired for all Planholders in connection with a particular investment.

    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.


                                                                            5/99

                         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.

   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.

   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.

   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.

   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.


                                       2
<PAGE>

dollars of issuers located in the following countries: 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.

Foreign Currency  Transactions.  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.

   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


                                       3
<PAGE>

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.

(1) Based on  remuneration  received by the Directors of the Corporation for the
    year ended  December 31, 1998.  Effective  January 16, 1998, the per meeting
    fee for  Directors  was  increased by $1,000,  which is allocated  among all
    Funds in the Fund Complex.

(2) As defined in the Corporation's prospectus, the Seligman Group of Investment
    Companies consists of eighteen investment companies.

(3) Deferred.

  The Corporation has a compensation  arrangement under which outside directors


                                       7
<PAGE>

may elect to defer receiving  their fees.  Under this  arrangement,  interest is
accrued on the deferred  balances.  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,  1998,  the  total  amount  of  deferred  compensation  (including
interest)  payable in respect of the  Corporation  to Mr.  Whitson was $132,346.
Messrs.  Merow and Pitney no longer defer current  compensation;  however,  they
have accrued  deferred  compensation  in the amounts of $124,695  and  $222,487,
respectively,  as of December  31,  1998.  The  Corporation  has applied for and
received  exemptive relief that would permit a director who has elected deferral
of his or her fees to choose a rate of return  equal to either (i) the  interest
rate on short-term  Treasury  bills, or (ii) the rate of return on the shares of
any of the  investment  companies  advised by the Manager,  as designated by the
director.  The Corporation may, but is not obligated to, purchase shares of such
investment  companies to hedge its  obligations in connection with this deferral
arrangement.

   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.

   The  Executive  Committee  of the  Board of  Directors  has the  power to (a)
determine the value of securities and assets owned by the Corporation, (b) elect
or appoint  officers of the  Corporation  to serve until the next meeting of the
Directors  succeeding such action and (c) determine the price at which shares of
Common Stock of the  Corporation  shall be issued and sold.  All action taken by
the  Executive  Committee  is recorded and reported to the Board of Directors at
their meeting  succeeding  such action.  The members of the Executive  Committee
consist of Mr. William C. Morris, Chairman, Richard R. Schmaltz, and Brian T.
Zino, President.

HOLDINGS OF PREFERRED STOCK, COMMON STOCK AND WARRANTS:

   As of March 31,  1999  holders  of record of  Preferred  Stock  totaled  572;
holders  of record of Common  Stock  totaled  42,861;  and  holders of record of
Warrants totaled 138. Insofar as is known by the Corporation,  no person owns or
controls or holds, directly or indirectly,  5% or more of the outstanding equity
securities,  except for Cede & Co., a nominee for The Depository  Trust Company,
P.O. Box 20, Bowling Green  Station,  New York, NY 10274-0020 who owns of record
47.61%  of  the  Corporation's  Common  Stock  outstanding  and  76.01%  of  the
Corporation's Preferred Stock outstanding.

   As of March 31, 1999 all directors and officers of the Corporation, as a
group, owned less than 1% of the Corporation's Common Stock.  As of that date,
no directors or officers owned any of the Corporation's Preferred Stock or
Warrants.  Mr. William C. Morris is Chairman and Chief Executive Officer of the
Manager and Chairman of the Board and Chief Executive Officer of the
Corporation.  Mr. Morris owns a majority of the outstanding voting securities
of the Manager.

   These securities of the Corporation shown as being owned  beneficially by the
directors and officers  include  shares held by or for the benefit of members of
their  families or held by a trust of which a director is a trustee but in which
they disclaim beneficial ownership.

                                   MANAGEMENT

   The  Corporation  pays  the  Manager  for  its  services  a  management  fee,
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  $14,754,214 in 1998,  $13,151,570  in 1997, and  $11,136,312 in
1996,   which  was  equivalent  to  annual  rates  of  .40%,   .40%,  and  .41%,
respectively, of the average daily net assets of the Corporation.

   Prior to March 31,  1998,  the Manager was party to a  Subadvisory  Agreement
with Seligman  Henderson Co. pursuant to which Seligman  Henderson Co. agreed to
provide  investment  advisory  services to the Corporation in respect of foreign
assets  to  the  extent  requested  by the  Manager.  On  March  30,  1998,  the
Subadvisory  Agreement was terminated in accordance with its terms.  The Manager
has no  present  plans to enter  into  similar  arrangements  in  respect of the
Corporation.  The Manager paid fees to Seligman  Henderson Co.,  pursuant to the
Subadvisory Agreement, of $1,361,562 and $1,192,207 for the years ended December
31, 1997 and 1996. For the period January 1, 1998 to March 30, 1998, the Manager
paid fees of $279,293 to Seligman Henderson Co.

   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


                                       8
<PAGE>

Corporation.  The Manager also  provides  senior  management  for Seligman  Data
Corp., a wholly-owned subsidiary of the Corporation and certain other investment
companies in the Seligman Group. 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.

   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.  On  December  23,  1988,  a  majority  of  the
outstanding  voting  securities of the Manager were  purchased by Mr. William C.
Morris,  and a simultaneous  recapitalization  of the Manager occurred.  See the
Appendix for a history of the Manager.

   Seligman Data Corp., a wholly-owned  subsidiary of the  Corporation,  acts as
the stockholder  service agent and dividend paying agent and performs,  at cost,
certain  recordkeeping  functions for the Corporation,  maintains the records of
shareholder  accounts and  furnishes  dividend  paying,  redemption  and related

64105,  serves as custodian for the  Corporation.  It also maintains,  under the
general  supervision of the Manager,  the accounting  records and determines the
net asset value for the Corporation.

                             BROKERAGE COMMISSIONS

   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 in the Seligman Group 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.

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

        Seligman's  beginnings  date back to 1837,  when  Joseph  Seligman,  the

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

TRI-CONTINENTAL CORPORATION
AN INVESTMENT YOU CAN LIVE WITH

Through nearly seven decades of dramatic economic,  political,  scientific,  and
social  change,   Tri-Continental  Corporation  has  remained  faithful  to  its
objective of providing a sound investment based primarily on carefully  selected
common stocks of well-managed, financially strong companies.

[LOGO]


<PAGE>


TRI-CONTINENTAL  CORPORATION IS A DIVERSIFIED CLOSED-END INVESTMENT COMPANY THAT
WAS  ESTABLISHED IN 1929. IT INVESTS  PRIMARILY TO PRODUCE  LONG-TERM  GROWTH OF
BOTH CAPITAL AND INCOME,  WHILE PROVIDING  REASONABLE CURRENT INCOME. ITS COMMON
STOCK IS TRADED ON THE NEW YORK STOCK EXCHANGE UNDER THE SYMBOL TY.

In a  dramatically  changing  world,  it's  comforting  to know that  stability,
tradition,   and   consistent   professional   service   can   still  be  found.
Tri-Continental   Corporation,   a  diversified  closed-end  investment  company
established in 1929,  strictly adheres to these values. The Corporation  invests
primarily in carefully selected common stocks of well-managed, financially sound
companies.  Its  investment  objective  is to produce  long-term  growth of both
capital and income, while providing reasonable current income.

Tri-Continental  Corporation has stayed faithful to this objective  during seven
decades of dramatic change,  including the country's deepest  depression,  wars,
and the stagnation and high inflation of the 1970s.  Through the passing fads of
the marketplace  and new theories of investment  management,  the  Corporation's
management  has adapted to the  conditions  of the day, but never  abandoned its
basic  philosophy  that a sound  investment  is  based  on  fundamentally  solid
investment values.

It is the rich past of  Tri-Continental  Corporation  that is  chronicled in the
pages that  follow.  As you read about the Great  Depression,  World War II, the
first television,  man landing on the moon, the invention of the microprocessor,
the gasoline  shortage of the 70s, and more recently,  the Dow Jones  Industrial
Average  breaking through to a remarkable  series of new highs,  Tri-Continental
Corporation is there every step of the way.

<PAGE>

AS EARLY AS 1925, A JUNIOR EMPLOYEE AT J. & W. SELIGMAN & CO. PROPOSED TO THE
PARTNERS THAT THE FIRM SPONSOR AN INVESTMENT COMPANY -- A COMPANY IN WHICH
INVESTORS POOL THEIR ASSETS FOR PROFESSIONAL MANAGEMENT.

The Partners  were used to taking  risks on their own account,  but taking risks
for thousands of Stockholders  was something  entirely  different.  However,  by
1929,  there were hundreds of  investment  companies,  and the investing  public
couldn't  seem to get  enough of them.  Ultimately,  the  decision  was made and
Tri-Continental Corporation was formed.

It was envisioned that the Corporation would invest its assets in the securities
of companies on three continents - North and South America and Europe.  The plan
prompted the name  Tri-Continental.  The new  corporation was to be a closed-end
investment   company  with  a  diversified   portfolio   selected  to  attain  a
conservative  objective - long-term  growth of capital and income and reasonable
current income. As a closed-end fund, Tri-Continental would issue a fixed number
of  shares  that  could be  bought  and  sold  primarily  on the New York  Stock
Exchange.

Tri-Continental  was to be  significantly  different from other closed-end funds
formed in the  United  States at the time.  Generally,  these  other  funds were
sponsored  by  investment  banking  firms to earn  underwriting  fees and  sales
commissions,  and the investment management was left to one or two staff members
who handled the job along with other duties. Not so at Tri-Continental.

The Corporation  would have its own staff of  university-trained  economists and
investment  analysts whose sole  responsibility was to study business conditions
and find sound investments for the Corporation's investment portfolio.

This  was  an  unprecedented   approach  to  investment   management.   However,
Tri-Continental   stood  firmly  behind  this  strategy,   carefully   selecting
investments  on the  basis of  thorough  research  and  first-hand  information.
Investment  risk was  diversified  widely by owning  many  different  securities
representing many different  industries and companies.  Management's goal was to
have consistency of approach, with flexibility to change with the times.

On January 12, 1929,  Tri-Continental  opened for business with a capitalization
of $52  million,  consisting  of $25 million of  Preferred  Stock with  warrants
attached,  and 1 million  shares of Common Stock with an initial net asset value
of $27 per share. The securities sold quickly.  With heavy demand for investment
company shares and  Tri-Continental's  success,  a second $50 million investment
company,  Tri-Continental  Allied Corporation,  was brought to market just eight
months later on August 15, 1929.

Less than three  months  later,  the great  bull  market of the 1920s came to an
abrupt  halt.  What had  seemed to be a world of  insatiable  demand  for common
stocks   quickly   turned  to  one  of   almost   unlimited   supply.   However,
Tri-Continental's  faith in the investment business never faltered.  Despite the
nationwide financial crisis that was only just beginning,  morale was diligently
maintained, and the research team focused on the task at hand.

THE DECADE AHEAD MARKED MAJOR CHANGES AT TRI-CONTINENTAL.

The Corporation entered into a contract to furnish investment advice and service
to Selected Industries Incorporated,  a leveraged closed-end investment company.
Later, as the entire  investment  industry began to consolidate,  many competing
investment companies were either forced into liquidation or found it impractical
to continue. Consequently, some

Tri-Continental  reduced  its  payroll  by 20%  and  bought  back  11.5%  of its
outstanding Preferred Stock. Even so, by the end of 1932,  Tri-Continental's net
asset value was negative.

Entering 1933,  Tri-Continental's investment policy was based on the belief that
the outlook for  American  business was  improving,  and that  security  prices,
especially those of common stocks, should reflect this improvement.  Even though
many of its securities yielded little or no return, the portfolio was positioned
by the end of the year with 70% invested in common stocks to take full advantage
of the  anticipated  recovery.  Tri-Continental's  action  proved  correct:  the
market, as measured by the Dow Jones Industrial Average (DJIA), began recovering
in 1933,  and by March 1937 had regained  nearly half of the losses  experienced
during the beginning of the decade.  In the summer of 1938, a rapid  recovery of
business  activity  began. By September  1938,  Tri-Continental  Corporation had
formed a new corporate subsidiary,  Union Securities Corporation,  to originate,
underwrite, and distribute securities.

The decade  ended with World War II just  around the  corner.  Production  lines
reached record levels, consumer incomes and retail sales substantially improved,
and   industrial   profits  and  dividends  rose  while  a  flurry  of  consumer
"stockpiling" began.

IN 1940, MUCH OF THE WORLD WAS AT WAR. AS THE US ECONOMY SHIFTED TO WAR-TIME
PRODUCTION, THERE WERE WIDE FLUCTUATIONS IN BUSINESS ACTIVITY AND SECURITIES
MARKETS.

During this time,  the  management of  Tri-Continental  maintained a diversified
portfolio of sound companies with adequate income and, most important,  remained
committed to a long-term approach to investing.  At the same time, Union Service
Corporation   was  organized  to  take  over  the  investment,   research,   and
administrative  services of  Tri-Continental,  and to provide  such  services to
Tri-Continental,  and to the funds previously served by the Corporation, under a
joint,  cost-sharing arrangement.  Prior to this arrangement,  Tri-Continental's
staff had provided the investment  research and administrative  functions to the
other  investment  companies  managed by J. & W.  Seligman & Co. on a fee basis.
This  arrangement had worked very well, but as the investment  companies grew in
size, the fairness of having one company pay fees to another came into question.
As a result, the concept of mutual ownership and mutual sharing made it possible
for  Tri-Continental  to  continue  to benefit  from the  country's  largest and
best-trained professional investment organization.

By the time the United  States  declared  war,  the prices of common  stocks had
fallen  considerably,  with the DJIA declining 6.5% between  December 6 (the day
before  the  attack  on  Pearl  Harbor)  and  December  10.  At  year-end  1941,
Tri-Continental's net asset value stood at only seven cents per share.

Nonetheless, the wisdom of taking a long-term view was demonstrated in the years
that  followed.  By the time World War II ended in 1945, the  Corporation's  net
asset value had risen to $13.07 per share. Management's investment

focus on the long-term,  post-war  outlook and its inclusion in the portfolio of
smaller  companies  with  unusual  investment  opportunities  provided  handsome
returns for Tri-Continental's Stockholders.

Once the US  began  to  adjust  to  peace-time  activity,  common  stocks  again
declined.  Political  uncertainty  in Europe and fears of a  business  recession
caused investors to maintain a conservative appraisal of earnings and dividends.
By the end of the decade,  however,  common stock prices again rose sharply, and
Tri-Continental's net asset value followed suit, as the portfolio had been fully
invested for most of the period.

THE NINETEEN FIFTIES BEGAN WITH THE CONTINUED ADJUSTMENT TOWARD PEACETIME
OPERATIONS.

Confidence was growing,  industrial production rising, commodity prices firming,
and the prices of common stocks soaring. However, the sudden shock of the Korean
conflict  and the fear of another  world war  temporarily  brought  stock prices
down.  By 1951,  the US  economy  was  dominated  by a shift from  peacetime  to
"garrison-state" conditions, which supported high levels of business activity in
the war  industries.  The wide  variations in equity prices demanded the careful
investment selection of Tri-Continental's approach.

The fifties  also marked  important  milestones  in  Tri-Continental's  history.
Selected  Industries  merged  with  Tri-Continental,  culminating  the  business
relationship  begun more than 20 years prior,  and increasing  Tri-Continental's
assets to more than $127 million. In 1951, Tri-Continental established a regular
quarterly dividend distribution policy. Most significant, the Corporation became
the  country's  largest,  diversified,  publicly  traded  closed-end  investment
company in 1951 - a  distinction  Tri-Continental  still holds  today.  Nineteen
fifty-six marked the first year in which Tri-Continental's  dividend payments to
both Preferred and Common Stockholders passed the $10 million mark.

Also in 1956, Union Securities Corp., the wholly-owned  securities  underwriting
subsidiary of Tri-Continental, transferred the portion of the

holding the investments for extended periods to realize the profit potential. In
this  business,  Tri-Continental  was a pioneer in what is an active area of the

THE BEGINNING OF THE SIXTIES BROUGHT WITH IT A MILD RECESSION,  DESPITE THE FACT
THAT THE ECONOMY WAS REACHING NEW HEIGHTS.

The forces  that  characterized  the  post-war  period were  largely  exhausted:
shortages no longer existed;  accumulated  consumer wants and needs were largely
satisfied;  domestic  and foreign  competition  was more  intense;  inflationary
pressures  subsided;  and the business  community was cautious.  Even though the
prices of common stocks fell in 1960, the goal of  Tri-Continental's  management
was to continue  the  tradition  of  carefully  managed,  thoroughly  researched
investments  that would  produce good capital and income  results.  For the next
five years, Tri-Continental's strategy proved rewarding as business activity was
strong, and the stock market, though subject to periodic corrections,  continued
its upward march. At the same time,  income taxes were staggering,  the Cold War
was getting colder,  and the fight for civil rights was dividing the nation.  If
ever there was a time for prudent, active management,  this was certainly one of
them.

Part of the Corporation's effort to keep up with the times was the establishment
of  a  new  company  to  provide  up-to-date   electronic  data  processing  and
shareholder  services.  In 1966,  Tri-Continental  and its associated  companies
formed  Union Data Service  Center,  known today as Seligman  Data Corp.  At the
time, Tri-Continental was believed to be the first diversified,  publicly traded
investment  company  to  undertake  the role of having its own  electronic  data
processing organization.

Seligman Data Corp. remains Tri-Continental's Stockholder Service agent today.

By 1967, the country reached the seventh year in the longest period of sustained
economic  expansion since the end of World War II.  Tri-Continental's  net asset
value hit a new high of $37.55,  dividend  distributions  had increased for four
consecutive years, and the net unrealized and realized gains were the largest to
date.

This large amount of net realized  capital gain was paid to Stockholders in 1967
- - - the first time Tri-Continental  Corporation made a capital gain distribution
to Stockholders.  Previously, the policy had been to retain net realized capital
gains to build net assets.  With this  change in policy came the strong  caution
that  capital  gain  distributions  must be  taken  in  additional  shares  if a
Stockholder  wished to keep the full amount of an  investment at work to produce
future  income  and  growth  of  capital  value.   It  was  also  in  1967  that
Tri-Continental's  Annual  Meetings began to be held around the country in order
to give as many Stockholders as possible the opportunity to meet the managers of
their investment. This tradition continues today.

Despite the nation's prosperity,  the decade ended on a slower note as investors
took a wait-and-see attitude,  influenced by economic uncertainty, an escalating
war in  Southeast  Asia,  and the first  hints that the  international  monetary
system,  with the US  dollar at its core,  was in  danger  of  collapsing.  Amid
mounting social and  environmental  concerns,  and rising inflation and interest
rates, the prices of common stocks declined substantially.

THE  MANAGEMENT OF  TRI-CONTINENTAL  VIEWED THE BEGINNING OF THE SEVENTIES AS AN
OPPORTUNITY TO STRENGTHEN THE PORTFOLIO'S INVESTMENT HOLDINGS.

Through 1972, the economy  recovered  slowly,  and the DJIA closed the year at a
record 1020. It was clear that economic and social  problems still existed,  but
Tri-Continental's  management was  optimistic  that the stocks of companies that
would improve earnings as business  conditions  improved would produce favorable
results.

Unfortunately,  in 1973, numerous events,  including the collapse of the world's
monetary  system and a four-fold  increase in the price of oil, sent the economy
into the  deepest  recession  since the Great  Depression.  The prices of common
stocks also suffered sharp declines.  The equity market's  problems  worsened in
1974 as rising unemployment,  double-digit  inflation,  and the political crisis
surrounding  Watergate left policy makers  befuddled.  Between  January 1973 and
September 1974, the market fell 42.6% - its worst  performance  since the 1930s.
The  Corporation  concentrated  on ensuring that the securities in the portfolio
were those of strong companies that represented reasonable risks. Less promising
holdings were reduced or eliminated.

The  investment  decisions  that were made in the first half of the decade  were
rewarded  in  the  second  half,  which  was  a  period  of  improving  economic
conditions,  more optimistic investor sentiment, rising corporate profits, and a
stronger  equity  market.   However,   as  the  decade  drew  to  a  close,  and
Tri-Continental  entered its 50th year,  evidence of another recession developed
and inflation accelerated. Interest rates rose to new highs, with the prime rate
charged by banks soaring to more than 20%.

IN 1981, CHANGE WAS TAKING PLACE AT TRI-CONTINENTAL.

As part of a corporate reorganization, J. & W. Seligman & Co. Incorporated
succeeded the Seligman partnership that began operations in 1864, and assumed
the responsibility for the investment management activities of Union Services
Corporation. Since then, Seligman has been directly responsible for providing
investment management and other services to Tri-Continental. This arrangement
with J. & W. Seligman & Co. Incorporated remains in effect today. Meanwhile, the
nation's economy was in a deep recession which curbed corporate profits and cast
a shadow on the outlook for the future.

A reversal  took place in the third  quarter of 1982,  and both stocks and bonds
did very well. Tri-Continental reaped the benefits of its earlier positioning of
the portfolio and  continued to cautiously  purchase more common stocks  through
the end of the year. The positive trend in the equity market continued into 1983
and beyond. Business activity began to slow in 1986; nonetheless,

Tri-Continental's   management  remained  optimistic  about  the  economy,   and
maintained a long-term investment focus.

Nineteen  eighty-seven,  however,  turned out to be more challenging than anyone
had expected.  The first eight months of the year saw soaring equity prices, but
the  market  corrected  a record  22.6% in one day on  October  19.  Fears of an
economic downturn, rising interest rates, and renewed inflation dominated, while
panic took hold of  individual  investors.  As many  open-end  mutual funds were
scrambling to sell investments to cash out fearful investors, Tri-Continental's

closed-end  structure  allowed it to purchase  common stocks at very  attractive
prices  and to remain  focused on the  long-term  investment  objectives  of its
Stockholders. And, by the end of the decade, the equity markets hit new highs.

IN 1990,  WHEN IRAQ  SUDDENLY  INVADED  KUWAIT,  BOTH THE STOCK AND BOND MARKETS
DROPPED SIGNIFICANTLY AND FEARS OF A RECESSION QUICKLY HEIGHTENED.

In response to this investment environment,  Tri-Continental  Corporation used a
two-pronged investment strategy,  raising the portfolio's cash position to 11.2%
and increasing the weightings in selected sectors such as energy.

In 1991,  Operation Desert Storm was in full swing, the USSR disintegrated,  and
the equity  markets  resumed their upward march.  However,  in 1994, the Federal
Reserve Board  increased  interest  rates six times and the DJIA posted a meager
total  return of 5.02%.  Nonetheless,  the  long-term  outlook was  improving as
interest rates peaked in late 1994, and Congress and the

nation had turned the corner toward a more balanced budget.

Tri-Continental's  management increased the equity weighting in the portfolio to
obtain both current income and capital  appreciation.  The portfolio was broadly
diversified as the  valuations of  large-capitalized  stocks soared,  and stocks
with reasonable value and strong long-term  potential were aggressively  sought.
This strategy proved to be on the mark in 1996 and 1997, as investors  witnessed
strong economic growth, low inflation,  increasing competitiveness of the United
States, and the DJIA breaking the 6000, 7000, and 8000 marks.

Overall, the 1990s have been a decade of great importance for the United States:
The country successfully  completed the transition from a high interest rate and
inflation  environment to one of low rates and little inflationary  pressure. It
also has been the  decade of  technology,  when  networking  and  semiconductors
became well-known terms.

What the 21st century has in store is unknown, but there is comfort in knowing
that while times change, values endure, and Tri-Continental Corporation will
stay true to its long-term investment objective. Tri-Continental: an investment
you can live with.

Established  in  1864,  J. & W.  Seligman's  more  than 130  years of  providing
financial  services  have been marked not by fanfare,  but rather by a quiet and
firm  adherence to managing  investments  and giving prudent  financial  advice.
Seligman is proud of its distinctive past and traditional values, which continue
to shape its business decisions and investment judgment.

Seligman's  beginnings  date back to 1837 when  Joseph  Seligman,  the oldest of
eight  brothers,  arrived in the United  States  from  Germany.  Nearly 30 years
later, in 1864, after achieving success as international  bankers, the Seligmans
established the investment firm of J. & W. Seligman & Co.

In the years that  followed,  Seligman  played a major role in the  geographical
expansion and industrial development of the United States. It helped finance the
westward path of the railroads and the building of the Panama Canal. In the late
1800s,  and early 1900s,  the firm was  instrumental  in financing the fledgling
American automobile and steel industries.

Throughout the first quarter of this century,  Seligman participated in hundreds
of successful  underwritings,  including  those for some of the  country's  most
important  companies:  United Artists Theatre Circuit,  Dodge Brothers,  General
Motors, Victor Talking Machine,  Minneapolis-Honeywell Regulator, and Maytag, to
name just a few.  In 1929,  Seligman  organized  its first  investment  company,
Tri-Continental Corporation,  today the nation's largest, diversified,  publicly
traded closed-end  investment company,  with more than $3.7 billion in assets as
of June 30,  1998.  In the  following  year,  the firm began  managing its first
mutual fund, Broad Street Investing Co. Inc., now known as Seligman Common Stock
Fund.
