THE FUND

INVESTMENT OBJECTIVE/PRINCIPAL STRATEGIES

          The Fund seeks  growth of  capital.  Income may be  considered  but is
incidental to the Fund's investment objective.

          The Fund uses the  following  strategies  to pursue its  objective  of
growth of capital.

   
          The Fund  generally  invests  at least 65% of its total  assets in the
common  stock of small US  companies.  Companies  are  selected for their growth
prospects.  The Fund uses a bottom-up stock selection approach.  This means that
the investment manager concentrates on individual company  fundamentals,  rather
than on a particular market sector. The Fund maintains a disciplined  investment
process that  focuses on downside  risks as well as upside  potential.  The Fund
avoids  "fad"  stocks  and those it  considers  overly  expensive  or  unusually
volatile.  In selecting  investments  the  investment  manager looks to identify
companies that typically display one or more of the following:
    

SMALL COMPANIES:                        o Positive operating cash flows
Companies with  market
capitalizations, at the time            o Management ownership
of purchase by the Fund of
$125 billion or less                    o A unique competitive advantage

                                        o Historically high returns on capital

The Fund  generally  sells a stock if its target price is reached,  its earnings
are  disappointing,  its revenue growth slows,  or its  underlying  fundamentals
deteriorate.

Although the Fund generally  concentrates  its investments in common stocks,  it
may invest up to 35% of its assets in preferred  stocks  securities  convertible
into common  stocks,  and stock purchase  warrants if the manager  believes they
offer  capital  growth  opportunities.  The  Fund may also  invest  in  American
Depositary  Receipts (ADRs),  which are  publicly-traded  instruments  generally
issued by  domestic  banks or trust  companies  that  represent  a security of a
foreign  issuer.  ADRs are quoted and settled in US  dollars.  The Fund uses the
same criteria in evaluating these securities as it does for common stocks.

As a defensive  measure,  the Fund may also invest up to 35% of its total assets
in fixed-income  securities  issued or guaranteed by the US government  (such as
treasury  bills,   notes  and  bonds),  its  agencies,   instrumentalities,   or
authorities; highly-rated corporate debt securities and certificates of deposit.
The Fund would  take this  defensive  position  only  temporarily  in seeking to
minimize  extreme  volatility  caused  by  adverse  market,  economic,  or other
conditions or in anticipating  significant  withdrawals from the Fund.  However,
such a position is inconsistent  with the Fund's principal  strategies and could
prevent the Fund from achieving its investment objective.

   
The Fund may invest up to 15% of its net assets in illiquid securities and up to
10% of its total assets in foreign  securities  which are held  directly  (which
does not include ADRs).  The Fund may also purchase put options in an attempt to
hedge against a decline in the price of securities it holds in its portfolio and
may lend portfolio securities.  The Fund generally does not invest a significant
amount of its assets, if any, in illiquid securities, foreign securities, or put
options.
    

The Fund may change its principal strategies, including the definition of "small
company," if the Fund's Board of Directors  believes doing so is consistent with
the Fund's objective of growth in capital.

As with any  mutual  fund,  there is no  guarantee  the Fund  will  achieve  its
objective.



                                       1

PRINCIPAL RISKS

Stock prices fluctuate.  Therefore, as with any fund that invests in stocks, the
Fund's net asset value will  fluctuate,  especially  in the short term.  You may
experience a decline in the value of your investment and you could lose money.

Small-company  stocks, as a whole, may experience larger price fluctuations than
large-company stocks or other types of investments. Small companies tend to have
shorter  operating  histories and may have less experienced  management.  During
periods of investor uncertainty, investor sentiment may favor larger, well-known
companies over small, lesser-known companies.

The Fund  seeks to reduce  the risks of  investing  in small  company  stocks by
adhering  to  its  disciplined  investment  process,  and  by  diversifying  its
investments  typically among more than 100 stocks and avoiding  concentration in
any one  industry.  The Fund  may,  however,  invest  more  heavily  in  certain
industries believed to offer good investment  opportunities.  To the extent that
an  industry  in which  the Fund is  invested  falls out of  favor,  the  Fund's
performance may be negatively affected.

The Fund may also be negatively affected by the broad investment  environment in
the US or international  securities markets, which is influenced by, among other
things, interest rates, inflation, politics, fiscal policy, and current events.

   
To the extent that the Fund invests some of it assets in higher-risk securities,
such as illiquid securities,  foreign securities,  or options, it may be subject
to higher price  volatility.  The Fund may lose money if it lends its securities
and the borrower does not return them.
    

The Fund may actively and frequently  trade stocks in its portfolio to carry out
its  principal   strategies.   A  high   portfolio   turnover  rate  results  in
correspondingly  greater transaction costs and a possible increase in short-term
capital gains and losses.  This may increase the Fund's expenses and it may have
tax consequences for investors in the Fund.

An  investment  in the Fund is not a  deposit  in a bank and is not  insured  or
guaranteed by the Federal Deposit Insurance  Corporation or any other government
agency.

PAST PERFORMANCE

The Fund offers three Classes of shares.  The  information  below  provides some
indication of the risks of investing in the Fund by showing how the  performance
of  Class A  shares  has  varied  year to  year,  as  well as how  each  Class's
performance  compares  to three  widely-used  measures  of small  company  stock
performance.

Although the Fund's fiscal year ends on September 30, the following  performance
information  is provided on a calendar year basis to assist you in comparing the
returns of the Fund with the  returns of other  mutual  funds.  How the Fund has
performed in the past, however, is not necessarily an indication of how the Fund
will perform in the future. Total returns will vary between each Class of shares
due to the different fees and expenses of each Class.

The Class A annual total  returns  presented in the bar chart do not reflect the
effect of any sales charges.  If these charges were included,  the returns would
be less. The average annual total returns presented in the table below the chart
do reflect the effect of the applicable  sales  charges.  Both the bar chart and
table assume that all dividends and capital gain distributions were reinvested.

The Russell 2000 Index, Russell 2000 Growth Index and the Lipper Small Cap Funds
Average are unmanaged  benchmarks that assume the  reinvestment of dividends and
capital  gain  distributions.  The Lipper  Average  does not  reflect  any sales
charges and the Russell  indices do not reflect any fees or sales  charges.  The
Russell 2000 Index  measures the  performance of small-cap  stocks,  the Russell
2000 Growth Index measures the  performance  of small-cap  growth stocks and the
Lipper  Average  measures  the  performance  of  mutual  funds  with  investment
objectives similar to the Fund.

FEES AND EXPENSES

The  table  below  summarizes  the  fees  and  expenses  that  you  may pay as a
shareholder of the Fund.  Each Class of shares has its own sales charge schedule
and is subject to different  ongoing  12b-1 fees.  Shareholder  fees are charged
directly to you.  Annual fund  operating  expenses are deducted from Fund assets
and are therefore paid indirectly by you and other shareholders of the Fund.

The Fund's Board of Directors provides broad supervision over the affairs of the
Fund.

The Fund's manager is J. & W. Seligman & Co. Incorporated  (Seligman),  100 Park
Avenue, New York, New York 10017.  Seligman manages the investment of the Fund's
assets,  including making purchases and sales of portfolio securities consistent
with the Fund's investment objective and strategies,  and administers the Fund's
business and other affairs.

   
Established in 1864,  Seligman  currently  serves as manager to 18 US registered
investment  companies,  which  offer  more than 50  investment  portfolios  with
approximately  $21.5  billion in assets as of December 31, 1998.  Seligman  also
provides  investment  management or advice to  institutional  or other  accounts
having an aggregate value at December 31, 1998, of approximately $9.4 billion.
    

The Fund pays Seligman a fee for its management services.  The fee rate declines
as the Fund's net assets increase.  It is equal to an annual rate of .95% of the
Fund's average daily net assets on the first $750 million of net assets and .85%
of the Fund's  average daily net assets in excess of $750 million.  The fee paid
by the Fund to Seligman for the Fund's fiscal year ended September 30, 1998, was
equal to an annual rate of 93% of the Fund's average daily net assets.

YEAR 2000

As  the   millennium   approaches,   mutual   funds,   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  mutual  funds,  the Fund relies upon
service providers and their computer systems for its day-to-day operations. Many
of the Fund's  service  providers in turn depend upon computer  systems of their
vendors. Seligman and SDC have established a year 2000 project team. The teams's
purpose is to assess the state of  readiness  of Seligman and SDC and the Fund'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 Seligman.  The Project Manager and other members of
the team  also  report  to the  Board  of  Directors  of the Fund and its  Audit
Committee.

   
The team has identified the service  providers and vendors who furnish  critical
services  or  software  systems  to the Fund,  including  securities  firms that
execute   portfolio   transactions  for  the  Fund  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 Fund.  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 200 issues  adversely  affect  the Fund.  The team  anticipates
finalizing these plans in the near future.

The Fund  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 Fund 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 Fund's critical service  providers are not successful in implementing  their
year 2000 plans,  the Fund's  operations  may be adversely  affected,  including
pricing,  securities  trading and  settlement,  and the provision of shareholder
services.

In addition,  the Fund may hold securities of issuers whose underlying  business
leaves them  susceptible to year 2000 issues.  The Fund may also hold securities
issued  by  governmental  or  quasi-governmental  issurers,  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
payments on any  indebtedness  and could have an adverse  impact on the value of
its securities. If the Fund holds these securities, the Fund's performance could
be negatively  affected.  Seligman  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 Fund may be adversely affected if
the exchanges markets,  depositories,  clearing agencies, or government or third
parties  responsible  for  infrastructure  needs do not address  their year 2000
issues in a satisfactory manner.
    

SDC has  informed  the Fund 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 Fund 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.

SHAREHOLDER INFORMATION

DECIDING WHICH CLASS OF SHARES TO BUY

Each of the Fund's  Classes  represents  an  interest in the same  portfolio  of
investments.  However,  each  Class has its own  sales  charge  schedule  and is
subject to different  ongoing 12b-1 fees. When deciding which Class of shares to
buy, you should consider, among other things.

  o The amount you plan to invest.
  o How long  you  intend  to remain  invested in the Fund, or another  Seligman
    mutual fund.
  o If you would  prefer to pay an initial  sales charge and lower ongoing 12b-1
    fees, or be  subject to a CDSC and pay higher  ongoing 12b-1 fees.
  o Whether  you may be eligible for reduced or no sales charges when you buy or
    sell shares.

Your  financial  advisor  will be able to help you decide  which Class of shares
best meets your needs.

CLASS A

  o Initial sales charge on Fund purchases, as set forth below.

(1) "Offering  Price" is the amount that you actually  pay for Fund  shares;  it
     includes the initial sales charge.
(2)  You will not pay a sales  charge on  purchases  of $1 million or more,  but
     you will be subject to a 1% CDSC if you sell your shares within 18 months.

  o Annual 12b-1 fee (for shareholder services) of up to 0.25%.
  o No sales charge on reinvested dividends or capital gain distributions.

CLASS B

  o No initial sales charge on purchases.
  o A declining CDSC on shares sold within 6 years of purchase.

</TABLE>

   
Your  purchase of Class B shares must be
for  less  than or more  but  less  than
$250,000,  because if you are  investing
$250,000  or more,  you will pay less in
fees  and  charges  if you  buy  another
Class of shares.
    

  o Annual 12b-1 fee (for distribution and shareholder services) of 1.00%.
  o Automatic  conversion  to Class  A  shares  after eight years,  resulting in
    lower ongoing 12b-1 fees.
  o No CDSC  on  redemptions of shares  purchased with  reinvested  dividends or
    capital gain distributions.



                                       7



<PAGE>

CLASS D

  o No initial sales charge on purchases.
  o A 1% CDSC on shares sold within one year of purchase.
  o Annual 12b-1 fee (for distribution and shareholder services) of 1.00%.
  o No  automatic  conversion  to Class A shares,  so you will be  subject to
    higher ongoing 12b-1 fees indefinitely.
  o No CDSC on redemptions of shares  purchased with reinvested  dividends
    or capital gains distributions.

   
Because 12b-1 fees are paid out of each Class's assets on an ongoing basis, over
time these fees will  increase  your  investment  expenses and may cost you more
than other types of sales charges.
    

The Fund's Board of Directors  believes  that no conflict of interest  currently
exists  between the Fund's  Class A, Class B, and Class D shares.  On an ongoing
basis,  the  Directors,  in the  exercise of their  fiduciary  duties  under the
Investment  Company Act of 1940 and  Maryland  law,  will seek to ensure that no
such conflict arises.

HOW CDSCS ARE CALCULATED

To minimize the amount of CDSC you may pay when you sell your  shares,  the Fund
assumes  that shares  acquired  through  reinvested  dividends  and capital gain
distributions (which are not subject to a CDSC) are sold first. Shares that have
been in your  account  long  enough so they are not  subject  to a CDSC are sold
next.  After these shares are  exhausted,  shares will be sold in the order they
were purchased (oldest to youngest). The amount of any CDSC that you pay will be
based on the  shares's  original  purchase  price or  current  net asset  value,
whichever is less.

   
You will not pay a CDSC  when you  exchange  shares  of the Fund to buy the same
class  of  shares  of any  other  Seligman  mutual  fund.  For  the  purpose  of
calculating the CDSC when you sell shares that you acquired by exchanging shares
of the Fund,  if will be  assumed  that you held the  shares  since the date you
purchased the shares of the Fund.

PRICING OF FUND SHARES

   
When you buy or sell shares, you do so at the Class's net asset value (NAV) next
calculated after Seligman  Advisors  accepts your request.  Any applicable sales
charge will be added to the purchase price for Class A shares.  Purchase or sale
orders  received by an  authorized  dealer or financial  advisor by the close of
regular  trading  on the New York  Stock  Exchange  (NYSE)  (normally  4:00 p.m.
Eastern  time) and  accepted by Seligman  Advisors  before the close of business
(5:00 p.m.  Eastern  time) on the same day will be  executed  at the Class's NAV
calculated  as of the close of  regular  trading  on the NYSE on that day.  Your
broker/dealer  or financial  advisor is responsible for forwarding your order to
Seligman advisors before the close of business.

If your buy or sell order is received by your broker/dealer or financial advisor
after the close of  regular  trading on the NYSE,  or is  accepted  by  Seligman
Advisors after the close of business,  the order will be executed at the Class's
NAV calculated as of the close of regular  trading on the next NYSE trading day.
When you sell shares, you receive the Class's per share NAV, less any applicable
CDSC.
    

The NAV of the Fund's shares is determined each day,  Monday through Friday,  on
days that the NYSE is open for trading.  Because of their higher 12b-1 fees, the
NAV of Class B and Class D shares will  generally be lower than the NAV of Class
A shares.

Securities  owned by the Fund are valued at current market  prices.  If reliable
market  prices  are  unavailable,  securities  are  valued  in  accordance  with
procedures approved by the Fund's Board of Directors.

NAV

Computed  separately  for each  Class by
dividing  that Class's  share of the net
assets of the Fund (ie.  its assets less
liabilities)  by  the  total  number  of
outstanding shares of the Class.

OPENING YOUR ACCOUNT

   
The Fund's  shares  are sold  through  authorized  broker/dealers  or  financial
advisors who have sales  agreements  with Seligman  Advisors.  There are several
programs  under which you may be eligible for reduced  sales  charges.  Ask your
financial advisor if any of these programs apply to you.

To make your initial  investment in the Fund,  contact your financial advisor or
complete and account  application and send it with your check directly to SDC at
the address  provided on the account application.  If you do not choose a Class,
your investment will automatically be made in Class A shares.
    

YOU MAY BUY  SHARES  OF THE FUND FOR ALL
TYPES OF TAX-DEFERRED  RETIREMENT PLANS.
CONTACT  RETIREMENT PLAN SERVICES AT THE
ADDRESS  OR PHONE  NUMBER  LISTED ON THE
INSIDE BACK COVER OF THIS PROSPECTUS FOR
INFORMATION  AND TO  RECEIVE  THE PROPER
FORMS.

The required minimum initial investments are:

   o Regular (non-retirement) accounts: $1,000

   o For accounts opened  concurrently with  Invest-A-Check:
     $100 to open if you will be making monthly investments 
     $250 to open if you will be making quarterly investments

   
If you buy shares by check and subsequently  sell the shares,  SDC will not send
your proceeds  until your check clears,  which could take up to 15 calendar days
from the date of your purchase.

You will be sent a statement  confirming your Fund purchase,  and any subsequent
transactions  in your  account.  You  will  also be sent at  least  annually,  a
statement  detailing all your  transactions  in the Fund and all other  Seligman
funds you own.  Duplicate account  statements will be sent to you free of charge
for the current year and most recent prior year.  Copies of year-end  statements
for prior years are  available  for a fee of $10 per year,  per account,  with a
maximum charge of $150 per account. Send your request and a check for the fee to
SDC.
    


    IF YOU WANT TO BE ABLE TO BUY, SELL, OR EXCHANGE SHARES BY TELEPHONE, YOU
  SHOULD COMPLETE AN APPLICATION WHEN YOU OPEN YOUR ACCOUNT. THIS WILL PREVENT
 YOU FROM HAVING TO COMPLETE A SUPPLEMENTAL ELECTION FORM (WHICH MAY REQUIRE
                     A SIGNATURE GUARANTEE) AT A LATER DATE.

HOW TO BUY ADDITIONAL SHARES

After you have made your initial investment, there are many options available to
make additional  purchases of Fund shares.  Shares may be purchased through your
authorized  financial  advisor,  or you may send a check directly to SDC. Please
provide  either an investment  slip or a note that  provides your name(s),  Fund
name and account  number.  Your investment will be made in the Class you already
own. Send investment checks to:
                              Seligman Data Corp.
                              P.O. Box 9766
                              Providence, RI 02940-5051

   
Your  check  must be in US  dollars  and be drawn on a US bank.  You may not use
third party or credit card convenience checks for investment.
    

You may also use the following account services to make additional investments.

INVEST-A-CHECK.  You  may buy  Fund  shares  electronically  from a  savings  or
checking account of an Automated  Clearing House (ACH) member bank. If your bank
is  not a  member  of  ACH,  the  Fund  will  debit  your  checking  account  by
preauthorized  checks.  You may buy Fund shares at regular monthly  intervals in
fixed amounts of $100 or more, or regular  quarterly  intervals in fixed amounts
of $250 or more if you use  Invest-A-Check,  you must continue to make automatic
investments until the Fund's minimum initial investment of $1,000 is met or your
account may be closed.

AUTOMATIC  DOLLAR-COST-AVERAGING.  If you have at least $5,000 in Seligman  Cash
Management  Fund,  you may  exchange  uncertificated  shares of that fund to buy
shares of the same  class of another  Seligman  mutual  fund at regular  monthly
intervals  in fixed  amounts of $100 or more or regular  quarterly  intervals in
fixed  amounts of $250 or more. If you exchange  Class A shares,  you may pay an
initial sales charge to buy Fund shares.

   
AUTOMATIC  CD TRANSFER.  You may instruct  your bank to invest the proceeds of a
maturing bank  certificate of deposit (CD) in shares of the Fund. If you wish to
use this service,  contact SDC or your financial advisor to obtain the necessary
forms.  Because your bank may charge you a penalty, it is not normally advisable
to withdraw CD assets before maturity.
    

DIVIDENDS  FROM  OTHER  INVESTMENTS.  You  may  have  your  dividends from other
companies  paid  to  the  Fund. (Dividend checks must include your name, account
number, Fund name, and Class of shares)

DIRECT  DEPOSIT.  You may buy Fund  shares  electronically  with funds from your
employer,  the IRS, or any other institution that provides direct deposit.  Call
SDC for more information.

HOW TO EXCHANGE SHARES BETWEEN THE SELIGMAN MUTUAL FUNDS

You may sell Fund  shares to buy shares of the same  Class of  another  Seligman
mutual fund, or you may sell shares of another  Seligman mutual fund to buy Fund
shares.  Exchanges will be made at each fund's  respective NAV. You will not pay
an initial sales charge when you exchange, unless you exchange Class A shares of
Seligman  Cash  Management  Fund to buy  Class A shares  of the Fund or  another
Seligman mutual fund.

   
Only your dividend and capital gain distribution  options and telephone services
will be automatically carried over to any new fund account. If you wish to carry
over any other  account  options  (for  example,  Invest-a-Check  or  Systematic
Withdrawals)  to the new fund, you must  specifically  request so at the time of
your exchange.
    

If you exchange into a new fund, you must exchange enough to meet the new fund's
minimum  initial  investment.  See "The Seligman Mutual Funds" for a list of the
funds available for exchange.  Before making an exchange  contact your financial
advisor or SDC to obtain the applicable  fund  prospectus(es),  which you should
read and understand before investing.

HOW TO SELL SHARES

The easiest way to sell Fund shares is by phone. If you have telephone services,
you may be able to use this service to sell Fund shares.  Restrictions  apply to
certain types of accounts.  Please see "Important  Policies That May Affect Your
Account."

When you sell Fund  shares by phone,  a check for the  proceeds  is sent to your
address of record.  If you have current ACH bank  information  on file,  you may
have the proceeds of the sale of your Fund shares  directly  deposited into your
bank account (typically, 3-4 business days after your shares are sold)

You may always send a written request to sell Fund shares. It may take longer to
get your money if you send your request by mail.

You will need to guarantee your signature(s) if the proceeds are:
          (1) $50,000 or more;
          (2) to be paid to someone  other than all account  owners, or
          (3) mailed to other than your address of record.

               --------------------------------------------------
               SIGNATURE  GUARANTEE:
               Protects   you  and  the  Fund  from   fraud.   It
               guarantees   that  a  signature   is  genuine.   A
               guarantee   must  be  obtained  from  an  eligible
               financial  institution.  Notarization  by a notary
               public is not an acceptable guarantee.
               ---------------------------------------------------

You may need to provide additional documents to sell Fund shares if you are:
   o a corporation
   o an executor or administrator
   o a trustee or custodian, or
   o in a retirement plan

If your Fund shares are represented by  certificates  you will need to surrender
the certificates to SDC before you sell your shares.

Contact your  financial  advisor or SDC's  Shareholder  Services  Department for
information on selling your shares under any of the above circumstances.

You may also use the following account service to sell Fund shares.

SYSTEMATIC  WITHDRAWAL  PLAN.  If you have at least $5,000 in the Fund,  you may
withdraw (sell) a fixed  amount  (minimum  of $50) of  uncertificated  shares at
regular  intervals.  A check will be sent to you at your address of record or if
you have  current  ACH bank  information  on file,  you may have  your  payments
directly deposited to your predesignated bank account in 3-4 business days after
your shares are sold. If you bought $1,000,000 or more of Class A shares without
an initial sales charge,  your  withdrawals  may be subject to a 1% CDSC if they
occur  within 18 months of  purchase.  If you own Class B or Class D shares  and
reinvest your dividends and capital gain distributions,  you may withdraw 12% or
10%,  respectively,  of the value of your Fund account (at the time of election)
annually without a CDSC.

You and your  broker/dealer  or  financial  advisor  will be able to  place  the
following requests by telephone, unless you indicate on your account application
that you do not want telephone services:
   o Sell  uncertificated  shares  (up to  $50,000  per day,  payable to account
     owner(s) and mailed to address of record)
   o Exchange shares between funds
   o Change dividend and/or capital gain distribution options
   o Change your address
   o Establish systematic withdrawals to address of record
    

If you do not  complete  an  account  application  when  you open  your  account
telephone services must be elected on a supplemental election form.

Restrictions apply to certain types of accounts:
   o Trust accounts on which the current trustee is not listed may not sell Fund
     shares by phone
   o Corporations may not sell Fund shares by phone.
   o IRAs may only exchange Fund shares or request address changes by phone
   o Group retirement plans may not sell Fund shares by phone,  plans that allow
     participants  to exchange by phone must  provide a letter of  authorization
     signed by the plan custodian or trustee and provide a supplemental election
     form signed by all plan participants.
Unless you have current ACH bank  information  on file,  you will not be able to
sell Fund shares by phone within thirty days following an address change.

Your request must be communicated to an SDC representative.  You may not request
any phone transactions via the automated access line.

   
You may cancel  telephone  services at any time by sending a written  request to
SDC. Each account owner, by accepting or adding telephone  services,  authorizes
each of the  other  owners to make  requests  by phone.  Your  broker/dealer  or
financial advisor  representative  may not establish  telephone services without
your written authorization. SDC will send written confirmation to the address of
record when telephone services are added or terminated.
    

During times of heavy call volume,  you may not be able to get through to SDC by
phone to request a sale or exchange of Fund shares.  In this case,  you may need
to write,  and it may take longer for your request to be  processed.  The Fund's
NAV may fluctuate during this time.

The Fund and SDC will not be liable for processing requests received by phone as
long as it was reasonable to believe that the request was genuine.

REINSTATEMENT PRIVILEGE

   
If you sell Fund shares,  you may,  within 120 calendar days, use part or all of
the  proceeds  to buy  shares  of the Fund or any  other  Seligman  mutual  fund
(reinstate  your  investment)  without paying an initial sales charge or, if you
paid a CDSC when you sold your  shares,  receiving  a credit for the  applicable
CDSC paid.  This privilege is available  only once each calendar  year.  Contact
your financial advisor for more information. You should consult your tax advisor
concerning possible tax consequences of exercising this privilege.

                                      paid in the same amount for each class.   
                                     

TAXES

The tax  treatment  of  dividends  and capital  gain  distributions  is the same
whether you take them in cash or reinvest  them to buy  additional  Fund shares.
Tax-deferred  retirement  plans are not taxed  currently on dividends or capital
gain distributions or on exchanges.

   
You may be taxed at different  rates on capital  gains  distributed  by the Fund
depending on the length of time the Fund holds its assets.
    

When you sell Fund shares any gain or loss you realize will generally be treated
as a  long-term  capital  gain or loss if you held your shares for more than one
year,  or as a  short-term  capital gain or loss if you held your shares for one
year or less. However, if you sell Fund shares on which a long-term capital gain
distribution  has been  received and you held the shares for six months or less,
any loss you realize  will be treated as a long-term  capital loss to the extent
that it offsets the long-term capital gain distribution.

An  exchange  of Fund  shares  is a sale  and may  result  in a gain or loss for
federal income tax purposes.

Each January you will be sent information on the tax status of any distributions
made during the previous calendar year. Because each shareholder's  situation is
unique,  you should always consult your tax advisor concerning the effect income
taxes may have on your individual investment.

FINANCIAL HIGHLIGHTS

   
The tables below are  intended to help you  understand  each  Class's  financial
performance  for the past five years or, if less than five years,  the period of
the Class's  operations.  Certain  information  reflects financial results for a
single  share of a Class that was held  throughout  the  periods  shown.  "Total
return"  shows the rate that you would have earned (or lost) on an investment in
the Fund,  assuming you  reinvested all your capital gain  distributions.  Total
returns do not reflect  any sales  charges.  Deloitte & Touche LLP,  independent
auditors,  have audited this  information.  Their report,  along with the Fund's
financial  statements,  is  included  in the  Fund's  annual  report,  which  is

                                  Fund History

The Fund was  incorporated  under the laws of the state of  Maryland  on July 9,
1984.


              Description of the Fund and Its Investments and Risks

Classification

The Fund is a diversified  open-end  management  investment  company,  or mutual
fund.

Investment Strategies and Risks

The following information regarding the Fund's investments and risks supplements
the information contained in the Fund's Prospectus.

       

   
Foreign Securities.  The Fund may invest in commercial paper and certificates of
deposit  issued by foreign  banks and may invest  directly and through  American
Depositary  Receipts  (ADRs) in other  securities  of foreign  issuers.  Foreign
investments  may be affected  favorably  or  unfavorably  by changes in currency
rates and exchange control regulation.  There may be less information  available
about a foreign company than about a US company and foreign companies may not be
subject to reporting  standards and requirements  comparable to those applicable
to US companies.  Foreign  securities  may not be as liquid as US securities and
there  may be  delays  and  risks  attendant  in  local  settlement  procedures.
Securities of foreign  companies may involve greater market risk than securities
of US  companies,  and  foreign  brokerage  commissions  and  custody  fees  are
generally higher than those in United States.  Investments in foreign securities
may also be subject to local economic or political risks, political instability,
the  possible  nationalization  of  issuers  and the  risk of  expropriation  or
restrictions  on the  repatriation  of proceeds of sale.  In  addition,  foreign
investments  may be subject to  withholding  and other  taxes.  ADRs,  which are
traded in dollars on US  Exchanges or  over-the-counter,  are issued by domestic
banks and evidence ownership of securities issued by foreign  corporations.  The
Fund 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  ADRs or to  commercial  paper and  certificates  of  deposit  issued by
foreign banks.
    

   
Repurchase  Agreements.  The Fund may  enter  into  repurchase  agreements  with
commercial  banks and  broker/dealers  as a short-term cash  management  tool. A
repurchase  agreement is an agreement  under which the Fund acquires a security,
generally a US Government obligation,  subject to resale at an agreed upon price
and date.  The resale price  reflects an agreed upon interest rate effective for
the period of time the Fund holds the  security and is unrelated to the interest
rate on the  security.  The Fund's  repurchase  agreements  will at all times be
fully collateralized.
    

Repurchase  agreements could involve certain risks in the event of bankruptcy or
other  default  by  the  seller,  including  possible  delays  and  expenses  in
liquidating the securities  underlying the agreement,  a decline in value of the
underlying  securities  and  a  loss  of  interest.  Repurchase  agreements  are
typically  entered into for periods of one week or less. The Fund will not enter
into repurchase  agreements of more than one week's duration if more than 10% of
its  net  assets  would  be  invested  in such  agreements  and  other  illiquid
securities.

   
Illiquid Securities. The Fund may invest up to 15% of its net assets in illiquid
securities,  including  restricted  securities  (i.e.,  securities  not  readily
marketable  without  registration  under the  Securities  Act of 1933 (the "1933
Act"))  and  other  securities  that are not  readily  marketable.  The Fund may
purchase  restricted  securities  that can be  offered  and  sold to  "qualified
institutional  buyers"  under Rule 144A of the 1933 Act, and the Fund'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
the Board of Directors make this  determination,  it 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.  It is not  possible  to predict  with  assurance  exactly how the
market for Rule 144A securities will further  evolve.  This investment  practice
could have the effect of increasing the 
    


                                       2
<PAGE>

level  of  illiquidity  in  the  Fund,  if  and to  the  extent  that  qualified
institutional  buyers become for a time  uninterested  in  purchasing  Rule 144A
securities.

Borrowing.  The Fund may borrow money only from banks and only for  temporary or
emergency  purposes  (but not for the  purchase of portfolio  securities)  in an
amount not in excess of 10% of the value of its total assets.  The Fund will not
purchase additional portfolio securities if the Fund has outstanding  borrowings
in excess of 5% of the value of its total assets.

   
Put Options.  The Fund may purchase  put options on portfolio  securities  in an
attempt  to  provide  a hedge  against  a  decrease  in the  market  price of an
underlying  security  held by the Fund.  The Fund will not purchase  options for
speculative purposes.
    

Purchasing  a put option  gives the Fund the right to sell,  and  obligates  the
writer to buy, the underlying  security at the exercise price at any time during
the option period.  This hedge protection is provided during the life of the put
option  since the Fund,  as holder of the put  option,  can sell the  underlying
security at the put exercise  price  regardless of any decline in the underlying
security's market price. In order for a put option to be profitable,  the market
price of the underlying  security must decline  sufficiently  below the exercise
price to cover the premium and  transaction  costs. By using put options in this
manner,  the Fund will reduce any profit it might otherwise have realized in the
underlying  security by the premium  paid for the put option and by  transaction
costs.

   
Because  a  purchased  put  option  gives  the  purchaser  a  right  and  not an
obligation,  the  purchaser  is not  required  to exercise  the  option.  If the
underlying  position  incurs  a gain,  the  Fund  would  let the  option  expire
resulting in a reduced  profit on the  underlying  security equal to the cost of
the put option premium and transaction costs.
    

When the Fund purchases an option,  it is required to pay a premium to the party
writing the option and a  commission  to the broker  selling the option.  If the
option is  exercised  by the Fund,  the premium and the  commission  paid may be
greater than the amount of the brokerage commission charged if the security were
to be purchased or sold  directly.  The cost of the put option is limited to the
premium plus  commission  paid.  The Fund's maximum  financial  exposure will be
limited to these costs.

   
The Fund may purchase  both listed and  over-the-counter  put options.  The Fund
will be  exposed  to the  risk of  counterparty  nonperformance  in the  case of
over-the-counter put options.
    

The  Fund's  ability  to engage in option  transactions  may be  limited  by tax
considerations.

   
Rights and  Warrants.  The Fund may invest in common  stock  rights and warrants
believed   by  the   investment   manager   to  provide   capital   appreciation
opportunities.  Common stock  rights and warrants  received as part of a unit or
attached to  securities  purchased  (i.e.,  not  separately  purchased)  are not
included in the Fund's investment restrictions regarding such securities.
    

The Fund may not invest in rights and warrants  if, at the time of  acquisition,
the  investment in rights and warrants would exceed 5% of the Fund'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, rights and warrants acquired by the
Fund in units or attached  to  securities  may be deemed to have been  purchased
without cost.

   
Lending of  Portfolio  Securities.  The Fund may lend  portfolio  securities  to
broker/dealers or other  institutions,  if the investment  manager believes such
loans will be beneficial  to the Fund.  The borrower must maintain with the Fund
cash or equivalent  collateral equal to at least 100% of the market value of the
securities  loaned.  During  the time  portfolio  securities  are on  loan,  the
borrower pays the Fund any dividend or interest paid on the securities. The Fund
may invest the collateral and earn  additional  income or receive an agreed upon
amount  of  interest  income  from the  borrower.  Loans  made by the Fund  will
generally be  short-term.  Loans are subject to termination at the option of the
Fund or the borrower.  The Fund may pay reasonable  administrative and custodial
fees in connection with a loan and may pay a negotiated  portion of the interest
earned on the  collateral to the borrower or placing  broker.  The Fund does not
have the right to vote  securities  on loan,  but would  terminate  the loan and
regain the right to vote if that were  considered  important with respect to the
investment.  The Fund may lose money if a borrower defaults on its obligation to
return  securities  and  the  value  of  the  collateral  held  by the  Fund  is
insufficient  to  replace  the  loaned  securities.  In  addition,  the  Fund is
responsible for any loss that might result from its investment of the borrower's
collateral.
    


                                       3
<PAGE>

Except as otherwise  specifically noted above, the Fund's investment  strategies
are not  fundamental  and the Fund, with the approval of the Board of Directors,
may change such strategies without the vote of shareholders.

Fund Policies

The Fund is subject to fundamental  policies that place  restrictions on certain
types of  investments.  These  policies  cannot be  changed  except by vote of a
majority of the Fund's outstanding voting securities.  Under these policies, the
Fund may not:

o    Borrow money,  except from banks for  temporary or emergency  purposes (but
     not for the  purchase of portfolio  securities)  in an amount not to exceed
     15% of the value of its total assets. The Fund will not purchase additional
     portfolio securities if the Fund has outstanding borrowings in excess of 5%
     of the value of its total assets;

o    Purchase securities on "margin," or sell "short", or write or purchase put,
     call,  straddle  or spread  options,  except  that the Fund may make margin
     deposits on future  contracts,  and may purchase put options solely for the
     purpose of hedging against a decline in the price of securities held in the
     Fund's portfolio;

o    Invest more than 5% of its total assets,  at market value, in securities of
     any  one  issuer   other  than  the  US   Government,   its   agencies   or
     instrumentalities,  buy  more  than  10% of the  voting  securities  of any
     issuer, or invest to control or manage any company;

o    Invest more than 5% of the value of its total assets,  at market value,  in
     securities  of any company  which,  with their  predecessors,  have been in
     operation  less  than  three  continuous  years,  provided,  however,  that
     securities  guaranteed by a company that (including  predecessors) has been
     in operation at least three  continuous  years shall be excluded  from this
     calculation;

o    Invest more than 25% of the value of its total assets in any one industry;

   
o    Invest  in  securities  issued  by other  investment  companies,  except in
     connection with a merger,  consolidation,  acquisition or reorganization or
     for the  purpose  of  hedging  the Fund's  obligations  under the  Deferred
     Compensation Plan for Directors;
    

o    Purchase or sell commodities and commodity contracts other than stock index
     futures contracts or purchase or hold real estate;

o    Purchase  or  hold  the  securities  of any  issuer,  if to its  knowledge,
     directors or officers of the Fund  individually  owning  beneficially  more
     than 0.5% of the  securities of that issuer own in the aggregate  more than
     5% of such securities;

o    Underwrite  the  securities of other issuers except insofar as the Fund may
     be deemed an underwriter  under the Securities Act of 1933, as amended,  in
     disposing of a portfolio security; or

o    Make loans,  except  loans of  portfolio  securities  (which loans would be
     fully  collateralized  and marked to market daily) and except to the extent
     the purchase of notes,  bonds or other  evidences of  indebtedness,  or the
     entry into repurchase agreements may be considered loans.

o    Invest more than 5% of the value of its net assets,  valued at the lower of
     cost or market, in warrants,  of which no more than 2% of net assets may be
     invested  in  warrants  not  listed  on the  New  York  or  American  Stock
     Exchanges.

The Fund  also may not  change  its  investment  objective  without  shareholder
approval.


                                       4
<PAGE>

Under the  Investment  Company Act of 1940 (1940 Act),  a "vote of a majority of
the outstanding voting securities" of the Fund means the affirmative vote of the
lesser of (l) more than 50% of the outstanding shares of the Fund; or (2) 67% or
more of the shares  present at a  shareholders'  meeting if more than 50% of the
outstanding shares are represented at the meeting in person or by proxy.

Temporary Defensive Position

In an  attempt  to respond to  adverse  market,  economic,  political,  or other
conditions,  the Fund may invest up to 35% of its total  assets in  fixed-income
securities  issued or guaranteed by the US Government  (such as treasury  bills,
notes, and bonds), its agencies, instrumentalities, or authorities; highly-rated
corporate debt securities and  certificates  of deposit,  or hold cash. The Fund
would take this  defensive  position  only  temporarily  in seeking to  minimize
extreme volatility caused by adverse market,  economic or other conditions or in
anticipating   significant  withdrawals  from  the  Fund.  Such  a  position  is
inconsistent  with the Fund's principal  strategies and could result in the Fund
not achieving its investment objective.

Portfolio Turnover

   
The Fund's  portfolio  turnover  rate is  calculated  by dividing  the lesser of
purchases  or sales of portfolio  securities  for the fiscal year by the monthly
average of the value of the portfolio  securities  owned during the fiscal year.
Securities whose maturity or expiration date at the time of acquisition were one
year or less are excluded from the calculation.  The Fund's  portfolio  turnover
rates for the fiscal  years  ended  September  30, 1998 and 1997 were 83.90% and
97.37%, respectively.

- ----------
(1)  For the Fund's fiscal year ended September 30, 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)  The Seligman Group of investment  companies consists of eighteen investment
     companies.
(d)  Deferred.

   
The Fund has a compensation  arrangement under which outside directors may elect
to defer receiving their fees. The Fund has adopted a Deferred Compensation Plan
under which a director who has elected  deferral of his or her fees may choose a
rate of return  equal to either (1) the  interest  rate on  short-term  Treasury
bills,  or (2)  the  rate  of  return  on the  shares  of any of the  investment
companies advised by J. & W. Seligman & Co.  Incorporated,  as designated by the
director.  The cost of such fees and earnings is included in directors' fees and
expenses,  and the accumulated  balance thereof is included in other liabilities
in the Fund's financial  statements.  The total amount of deferred  compensation
(including  earnings)  payable  in  respect  of the  Fund to Mr.  Whitson  as of
September 30, 1998 was $13,492. Messrs. Merow and Pitney no longer defer current
compensation; however, they have accrued deferred compensation in the amounts of
$22,181 and $13,644, respectively, as of September 30, 1998.

The Fund  may,  but is not  obligated  to,  purchase  shares of  Seligman  Group
investment  companies to hedge its  obligations  in  connection  with the Fund's
Deferred Compensation Plan.

J. & W. Seligman & Co.  Incorporated  (Seligman) manages the Fund. Seligman is a
successor  firm to an  investment  banking  business  founded  in 1864 which has
thereafter provided investment services to individuals,  families, institutions,
and  corporations.  On December 29, 1988, a majority of the  outstanding  voting

The Fund pays Seligman a management fee for its services,  calculated  daily and
payable  monthly.  The  management  fee is equal to .95% per annum of the Fund's
average  daily net assets on the first  $750  million of net assets and .85% per
annum of the Fund's average daily net assets in excess of $750 million.  For the

The Fund  pays  all of its  expenses  other  than  those  assumed  by  Seligman,
including  brokerage  commissions,  administration,   shareholder  services  and
distribution  fees,  fees and expenses of  independent  attorneys  and auditors,
taxes and governmental fees,  including fees and expenses of qualifying the Fund
and  its  shares  under  Federal  and  State  securities  laws,  cost  of  stock
certificates  and expenses of repurchase  or  redemption of shares,  expenses of
printing and distributing reports,  notices and proxy materials to shareholders,

expenses.

The Management  Agreement  provides that Seligman will not be liable to the Fund
for any error of judgment or mistake of law, or for any loss  arising out of any
investment,  or for any act or  omission  in  performing  its  duties  under the
Agreement,  except for willful  misfeasance,  bad faith,  gross  negligence,  or
reckless disregard of its obligations and duties under the Agreement.

   
The Management  Agreement was initially  approved by the Board of Directors at a
Meeting  held on October 11, 1988 and by the  shareholders  at a meeting held on
December 15, 1988. Amendments to the Management Agreement,  effective January 1,
1996, to increase the fee rate payable to the Manager by the Fund, were approved
by the Board of  Directors on September  21, 1995 and by the  shareholders  at a
special  meeting  held on December  12,  1995.  The  Management  Agreement  will
continue in effect  until  December 31 of each year if (1) 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 Fund
and by a vote  of a  majority  of the  Directors  who  are  not  parties  to the
Management  Agreement or interested  persons of any such party) and (2) Seligman
shall not have  notified  the Fund at least 60 days prior to  December 31 of any
year that it does not desire such continuance.  The Management  Agreement may be
terminated  by the Fund or by Seligman,  without  penalty,  on 60 days'  written
notice  to  Seligman  and  will  terminate  automatically  in the  event  of its
assignment.  The Fund has  agreed to change  its name  upon  termination  of the
Management  Agreement if continued use of the name would cause  confusion in the
context of Seligman's business.
    

Officers,  directors  and  employees  of  Seligman  are  permitted  to engage in
personal securities transactions, subject to Seligman's Code of Ethics. The Code
of Ethics  proscribes  certain  practices  with  regard to  personal  securities
transactions and personal  dealings,  provides a framework for the reporting and
monitoring of personal securities transactions by Seligman's Compliance Officer,
and sets forth a  procedure  of  identifying,  for  disciplinary  action,  those
individuals who violate the Code of Ethics. The Code of Ethics prohibits each of
the  officers,  directors and employees  (including  all portfolio  managers) of
Seligman from purchasing or selling any security that the officer,  director, or
employee knows or believes (1) was  recommended by Seligman for purchase or sale
by any client,  including the Fund, within the preceding two weeks, (2) has been
reviewed by Seligman  for  possible  purchase or sale within the  preceding  two
weeks, (3) is being purchased or sold by any client,  (4) is being considered by
a research analyst,  (5) is being acquired in a private placement,  unless prior
approval has been obtained from Seligman's  Compliance  Officer, or (6) is being
acquired during an initial or secondary public offering. The Code of Ethics also
imposes a strict standard of confidentiality  and requires portfolio managers to
disclose  any  interest  they may have in the  securities  or issuers  that they
recommend for purchase by any client.

The Code of Ethics also  prohibits  (1) each  portfolio  manager or member of an
investment  team from  purchasing or selling any security  within seven calendar
days of the  purchase or sale of the security by a client's  account  (including
investment  company accounts) for which the portfolio manager or investment team
manages;  and (2) each employee from engaging in short-term  trading (a purchase
and sale or vice-versa  within 60 days). Any profit realized  pursuant to either
of these prohibitions must be disgorged.

Officers,  directors,  and  employees  are  required,  except under very limited
circumstances,  to engage in personal securities transactions through Seligman's
order  desk.  The order  desk  maintains  a list of  


                                       11

securities  that may not be purchased  due to a possible  conflict with clients.
All  officers,  directors  and  employees  are also  required  to  disclose  all
securities beneficially owned by them on December 31 of each year.

Rule 12b-1 Plan

   
The Fund has adopted an  Administration,  Shareholder  Services and Distribution
Plan (12b-1  Plan) in  accordance  with  Section  12(b) of the 1940 Act and Rule
12b-1 thereunder.

Under the 12b-1 Plan, the Fund may pay to Seligman  Advisors an  administration,
shareholder  services  and  distribution  fee in respect of the Fund's  Class A,
Class B, and Class D shares.  Payments under the 12b-1 Plan may include, but are
not limited to: (1) compensation to securities  dealers and other  organizations
(Service  Organizations) for providing  distribution  assistance with respect to
assets  invested in the Fund;  (2)  compensation  to Service  Organizations  for
providing administration, accounting and other shareholder services with respect
to Fund  shareholders;  and (3)  otherwise  promoting  the sale of shares of the
Fund,  including  paying for the preparation of advertising and sales literature
and the printing and distribution of such promotional materials and prospectuses
to  prospective  investors and defraying  Seligman  Advisors'  costs incurred in
connection  with its  marketing  efforts  with  respect  to  shares of the Fund.
Seligman,  in its sole  discretion,  may also make similar  payments to Seligman
Advisors  from its own  resources,  which may  include the  management  fee that
Seligman receives from the Fund.  Payments made by the Fund under the 12b-1 Plan
are intended to be used to encourage sales of the Fund, as well as to discourage
redemptions.

Fees paid by the Fund under the 12b-1  Plan with  respect to any class of shares
may not be used to pay expenses incurred solely in respect of any other class or
any other Seligman  fund.  Expenses  attributable  to more than one class of the
Fund will be  allocated  between the classes in  accordance  with a  methodology
approved by the Fund's Board of  Directors.  The Fund may  participate  in joint
distribution  activities  with other  Seligman  funds,  and the expenses of such
activities will be allocated among the applicable funds based on relative sales,
in accordance with a methodology approved by the Board.

Class A 

Under the 12b-1 Plan, the Fund,  with respect to Class A shares,  pays quarterly
to  Seligman  Advisors  a  service  fee at an  annual  rate of up to .25% of the
average  daily net asset  value of the  Class A shares.  These  fees are used by
Seligman Advisors  exclusively to make payments to Service  Organizations  which
have entered into agreements with Seligman Advisors.  Such Service Organizations
receive  from  Seligman  Advisors  a  continuing  fee of up to .25% on an annual
basis,  payable  quarterly,  of the  average  daily net assets of Class A shares
attributable  to the  particular  Service  Organization  for providing  personal
service and/or maintenance of shareholder  accounts.  The fee payable to Service
Organizations from time to time shall,  within such limits, be determined by the
Directors of the Fund.  The Fund is not  obligated to pay Seligman  Advisors for
any such  costs it  incurs  in excess of the fee  described  above.  No  expense
incurred in one fiscal year by Seligman  Advisors with respect to Class A shares
of the Fund may be paid from  Class A 12b-1 fees  received  from the Fund in any
other fiscal year.  If the Fund's 12b-1 Plan is terminated in respect of Class A
shares,  no amounts (other than amounts  accrued but not yet paid) would be owed
by the Fund to  Seligman  Advisors  with  respect  to Class A shares.  The total
amount  paid by the Fund to  Seligman  Advisors in respect of Class A shares for
the fiscal year ended September 30, 1998 was  $1,175,841,  equivalent to .23% of
the Class A shares' average daily net assets.

Class B

Under the 12b-1 Plan, the Fund,  with respect to Class B shares,  pays monthly a
12b-1 fee at an annual rate of up to 1% of the average  daily net asset value of
the Class B shares. The fee is comprised of (1) a distribution fee equal to .75%
per annum,  which is paid  directly to a third  party,  FEP  Capital,  L.P.,  to
compensate  it for having  funded,  at the time of sale of Fund  shares (i) a 4%
commission  payment to Service  Organizations in connection with the sale of the
Class B shares and (ii) a payment of up to .25% of sales to Seligman Advisors to
help defray its costs of distributing  Class B shares;  and (2) a service fee 
    


                                       13
<PAGE>

   
of up to .25% per annum which is paid to Seligman  Advisors.  The service fee is
used by Seligman Advisors exclusively to make payments to Service  Organizations
which  have  entered  into  agreements  with  Seligman  Advisors.  Such  Service
Organizations  receive from Seligman Advisors a continuing  service fee of up to
 .25% on an annual basis,  payable quarterly,  of the average daily net assets of
Class B shares attributable to the particular Service Organization for providing
personal  service  and/or  maintenance  of  shareholder  accounts.  The  amounts
expended by  Seligman  Advisors  or FEP  Capital,  L.P. in any one year upon the
initial purchase of Class B shares of the Fund may exceed the 12b-1 fees paid by
the Fund in that  year.  The Fund's  12b-1 Plan  permits  expenses  incurred  in
respect of Class B shares in one fiscal  year to be paid from Class B 12b-1 fees
received from the Fund in any other fiscal year; however, in any fiscal year the
Fund is not  obligated  to pay any 12b-1  fees in  excess of the fees  described
above.  Seligman Advisors and FEP Capital,  L.P. are not reimbursed for expenses
which  exceed such fees.  If the Fund's 12b-1 Plan is  terminated  in respect of
Class B shares,  no amounts (other than amounts  accrued but not yet paid) would
be owed by that Fund to Seligman  Advisors or FEP Capital,  L.P. with respect to
Class B shares.  The total  amount paid by the Fund in respect of Class B shares
for the fiscal year ended September 30, 1998 was $796,405,  equivalent to 1% per
annum of the average daily net assets of Class B shares.

Class D

Under the 12b-1 Plan, the Fund, with respect to Class D shares,  pays monthly to
Seligman Advisors a 12b-1 fee at an annual rate of up to 1% of the average daily
net asset value of the Class D shares.  The Fee is used by Seligman  Advisors as
follows:  During  the  first  year  following  the  sale of  Class D  shares,  a
distribution fee of .75% of the average daily net assets attributable to Class D
share is used, along with any CDSC proceeds,  to (1) reimburse Seligman Advisors
for its payment at the time of sale of Class D shares of a .75% sales commission
to Service Organizations, and (2) pay for other distribution expenses, including
paying for the preparation of advertising and sales  literature and the printing
and distribution of such  promotional  materials and prospectuses to prospective
investors and other marketing costs of Seligman  Advisors.  In addition,  during
the first year following the sale of Class D shares, a service fee of up to .25%
of the average daily net assets  attributable  to such Class D shares is used to
reimburse  Seligman Advisors for its prepayment to Service  Organizations at the
time of sale of Class D shares of a  service  fee of up to .25% of the net asset
value of the Class D share sold (for  shareholder  services  to be  provided  to
Class D shareholders  over the course of the one year immediately  following the
sale). The payment to Seligman  Advisors is limited to amounts Seligman Advisors
actually  paid to Service  Organizations  at the time of sale as  service  fees.
After the initial one-year period following a sale of Class D shares, the entire
12b-1 fee  attributable to such Class D shares is paid to Service  Organizations
for providing  continuing  shareholder  services and distribution  assistance in
respect of assets  invested  in the Fund.  The total  amount paid by the Fund in
respect of Class D shares  for the fiscal  year  ended  September  30,  1998 was
$3,588,957,  equivalent to 1% per annum of the average daily net assets of Class
D shares.

The amounts expended by Seligman  Advisors in any one year with respect to Class
D shares of the Fund may  exceed  the 12b-1  fees paid by the Fund in that year.
The Fund's 12b-1 Plan permits expenses  incurred by Seligman Advisors in respect
of Class D shares in one  fiscal  year to be paid from Class D 12b-1 fees in any
other fiscal year;  however, in any fiscal year the Fund is not obligated to pay
any 12b-1 fees in excess of the fees described above.

As of September 30, 1998 Seligman Advisors has incurred $308,875 of unreimbursed
expenses in respect of the Fund's  Class D shares.  This amount is equal to .12%
of the net assets of Class D at September 30, 1998.

If the 12b-1 Plan is terminated in respect of Class D shares,  no amounts (other
than  amounts  accrued  but not yet paid)  would be owed by the Fund to Seligman
Advisors with respect to Class D shares.

Payments  made by the Fund  under  the  12b-1  Plan for its  fiscal  year  ended
September  30, 1998,  were spent on the  following  activities  in the following
amounts:

The 12b-1 Plan was  approved  on March 19,  1992 by the  Directors,  including a
majority of the  Directors who are not  "interested  persons" (as defined in the
1940 Act) of the Fund and who have no direct or indirect  financial  interest in
the  operation  of the Plan or in any  agreement  related to the 12b-1 Plan (the
"Qualified Directors") and was approved by shareholders of the Fund at a Special
Meeting of the Shareholders held on May 1, 1992. The 12b-1 Plan became effective
in respect of the Class A shares on June 1, 1992. The 12b-1 Plan was approved in
respect of the Class B shares on March 21, 1996 by the Board of Directors of the
Fund, including a majority of the Qualified  Directors,  and became effective in
respect of the Class B shares on April 22, 1996.  The 12b-1 Plan was approved in
respect of the Class D shares on March 18,  1993 by the  Directors,  including a
majority of the  Qualified  Directors,  and became  effective  in respect of the
Class D shares on May 1, 1993.  The 12b-1  Plan will  continue  in effect  until
December 31 of each year so long as such  continuance is approved  annually by a
majority  vote of both the  Directors of the Fund and the  Qualified  Directors,
cast in person at a meeting  called for the purpose of voting on such  approval.
The 12b-1 Plan may not be amended to increase  materially the amounts payable to
Service Organizations with respect to a class without the approval of a majority
of the  outstanding  voting  securities of the class.  If the amount  payable in
respect  of Class A shares  under the 12b-1  Plan is  proposed  to be  increased
materially, the Fund will either (1) permit holders of Class B shares to vote as
a separate class on the proposed increase or (2) establish a new class of shares
subject to the same payment under the 12b-1 Plan as existing Class A shares,  in
which case the Class B shares will thereafter convert into the new class instead
of into  Class A shares.  No  material  amendment  to the 12b-1 Plan may be made
except by vote of a majority of both the Directors and the Qualified Directors.
    

The 12b-1 Plan  requires  that the  Treasurer  of the Fund shall  provide to the
Directors,  and the Directors shall review, at least quarterly, a written report
of the amounts expended (and purposes therefor) under the 12b-1 Plan. Rule 12b-1
also  requires  that the  selection  and  nomination  of  Directors  who are not
"interested  persons" of the Fund be made by such disinterested  Directors.  The
12b-1 Plan is reviewed by the Directors annually.

   
Seligman  Services acts as a broker/dealer  of record for  shareholder  accounts
that do not have a designated  financial advisor and receives  compensation from
the Fund pursuant to the 12b-1 Plan for providing  personal services and account
maintenance  to such accounts and other  distribution  services.  For the fiscal
years ended  September 30, 1998,  1997,  and 1996,  Seligman  Services  received
distribution  and  service  fees from the Fund  pursuant  to its  12b-1  Plan of
$87,176, $65,586, and $73,340, respectively.
    

                    Brokerage Allocation and Other Practices

Brokerage Transactions

Seligman  will seek the most  favorable  price and execution in the purchase and
sale of portfolio  securities  of the Fund.  When two or more of the  investment
companies in the Seligman Group or other investment advisory clients of Seligman
desire  to buy or sell  the  same  security  at the same  time,  the  securities
purchased or sold are allocated by Seligman 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.


                                       15
<PAGE>

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

   
For the fiscal years ended  September 30, 1998,  1997,  and 1996,  the Fund paid
total  brokerage  commissions to others for execution,  research and statistical
services in the amounts of $1,769,832,  $1,446,040, and $956,356,  respectively.
The amount of brokerage  commissions  paid by the Fund has increased  materially
from 1996 due to an increase in portfolio turnover.
    

Commissions

For the fiscal years ended September 30, 1998,  1997, and 1996, the Fund did not
execute  any  portfolio  transactions  with,  and  therefore  did  not  pay  any
commissions  to, any  broker  affiliated  with  either  the Fund,  Seligman,  or
Seligman Advisors.

Brokerage Selection

Consistent  with seeking the most  favorable  price and execution when buying or
selling portfolio  securities,  Seligman may give consideration to the research,
statistical,  and other services furnished by brokers or dealers to Seligman for
its use,  as well as 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 Seligman to be beneficial to the Fund. In
addition,  Seligman  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
Fund 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 Seligman in  connection  with its  services to clients  other than the
Fund.

Directed Brokerage

During its fiscal year ended  September  30, 1998  neither the Fund nor Seligman
directed  any of the  Fund's  brokerage  transactions  to a  broker  because  of
research services provided.

Regular Broker-Dealers

   
During its fiscal  year  ended  September  30,  1998,  the Fund did not  acquire
securities of its regular brokers or dealers (as defined in Rule 10b-1 under the
1940 Act) or of their parents.
    

                       Capital Stock and Other Securities

Capital Stock

The Fund is authorized to issue 500,000,000 shares of capital stock, each with a
par value of $0.10, divided into three classes, designated Class A, Class B, and
Class D shares.  Each share of the  Fund's  Class A, Class B and Class D capital
stock is equal as to earnings,  assets, and voting privileges,  except that each
class bears its own separate distribution and, potentially,  certain other class
expenses and has  exclusive  voting rights with respect to any matter to which a
separate vote of any class is required by the 1940 Act or Maryland law. The Fund
has  adopted  a  multiclass  plan  pursuant  to Rule  18f-3  under  the 1940 Act
permitting  the  issuance  and sale of  multiple  classes  of common  stock.  In
accordance  with the  Articles  of  Incorporation,  the Board of  Directors  may
authorize  the  creation  of  additional  classes  of  common  stock  with  such
characteristics as are permitted by the multiclass plan and Rule 18f-3. The 1940
Act requires that where more than one class exists, each class must be preferred
over all other  classes  in  respect of assets  specifically  allocated  to such
class.  All  shares  have  noncumulative  voting  


                                       16
<PAGE>

rights for the election of directors.  Each outstanding  share is fully paid and
non-assessable,  and each is  freely  transferable.  There  are no  liquidation,
conversion, or preemptive rights.

Other Securities

The Fund has no authorized securities other than capital stock.

                   Purchase, Redemption, and Pricing of Shares

Purchase of Shares

Class A

Class A shares may be  purchased  at a price  equal to the next  determined  net
asset value per share, plus an initial sales charge.

Purchases  of Class A shares by a "single  person"  (as  defined  below)  may be
eligible for the following reductions in initial sales charges:

Volume  Discounts  are provided if the total  amount  being  invested in Class A
shares of the Fund alone,  or in any  combination  of shares of the other mutual
funds in the Seligman Group which are sold with an initial sales charge, reaches
levels indicated in the sales charge schedule set forth in the Prospectus.

The Right of  Accumulation  allows an  investor  to  combine  the  amount  being
invested in Class A shares of the Fund and shares of the other  Seligman  mutual
funds sold with an initial sales charge with the total net asset value of shares
of those mutual funds  already owned that were sold with an initial sales charge
and the total net asset value of shares of Seligman Cash  Management  Fund which
were acquired  through an exchange of shares of another  Seligman mutual fund on
which there was an initial  sales  charge at the time of  purchase to  determine
reduced  sales charges in accordance  with the schedule in the  prospectus.  The
value of the  shares  owned,  including  the value of shares  of  Seligman  Cash
Management  Fund  acquired in an exchange of shares of another  Seligman  mutual
fund on which there was an initial  sales charge at the time of purchase will be
taken into account in orders placed through a dealer,  however, only if Seligman
Advisors  is  notified  by an  investor  or a dealer of the amount  owned by the
investor  at  the  time  the  purchase  is  made  and  is  furnished  sufficient
information to permit confirmation.

A Letter of Intent allows an investor to purchase Class A shares over a 13-month
period at reduced  initial sales charges in accordance  with the schedule in the
Prospectus,  based on the  total  amount  of Class A shares of the Fund that the
letter states the investor intends to purchase plus the total net asset value of
shares that were sold with an initial sales charge of the other Seligman  mutual
funds  already  owned and the total net asset value of shares of  Seligman  Cash
Management  Fund which were  acquired  through an  exchange of shares of another
Seligman  mutual fund on which there was an initial  sales charge at the time of
purchase.  Reduced  sales  charges  also may apply to  purchases  made  within a
13-month  period starting up to 90 days before the date of execution of a letter
of intent.

   
CDSC Applicable to Class A Shares.  Class A shares purchased  without an initial
sales  charge  in  accordance  with the  sales  charge  schedule  in the  Fund's
Prospectus,  or pursuant to a Volume Discount, Right of Accumulation,  or Letter
of Intent  are  subject to a CDSC of 1% on  redemptions  of such  shares  within
eighteen months of purchase. Employee benefit plans eligible for net asset value
sales (as described  below) may be subject to a CDSC of 1% for  terminations  at
the plan level only, on redemptions of shares  purchased  within eighteen months
prior to plan  termination.  The 1% CDSC  will be  waived  on  shares  that were
purchased   through  Morgan  Stanley  Dean  Witter  &  Co.  by  certain  Chilean
institutional  investors (i.e. pension plans,  insurance  companies,  and mutual
funds). Upon redemption of such shares within an eighteen-month  period,  Morgan
Stanley Dean Witter will reimburse  Seligman  Advisors a pro rata portion of the
fee it received from Seligman Advisors at the time of sale of such shares.
    


                                       17
<PAGE>

See "CDSC  Waivers"  below for other  waivers which may be applicable to Class A
shares.

Persons  Entitled To  Reductions.  Reductions  in initial sales charges apply to
purchases  of Class A shares  by a "single  person,"  including  an  individual;
members of a family  unit  comprising  husband,  wife and minor  children;  or a
trustee or other fiduciary  purchasing for a single fiduciary account.  Employee
benefit plans qualified under Section 401 of the Internal  Revenue Code of 1986,
as amended,  organizations  tax exempt  under  Section  501(c)(3) or (13) of the
Internal  Revenue Code, and  non-qualified  employee  benefit plans that satisfy
uniform criteria are considered  "single persons" for this purpose.  The uniform
criteria are as follows:

     1.  Employees  must  authorize the  employer,  if requested by the Fund, to
receive in bulk and to distribute to each participant on a timely basis the Fund
prospectus, reports, and other shareholder communications.

     2.  Employees  participating  in a plan will be  expected  to make  regular
periodic  investments (at least annually).  A participant who fails to make such
investments  may be dropped  from the plan by the employer or the Fund 12 months
and 30 days after the last regular investment in his account. In such event, the
dropped participant would lose the discount on share purchases to which the plan
might then be entitled.

     3. The employer  must solicit its employees  for  participation  in such an
employee  benefit plan or authorize  and assist an  investment  dealer in making
enrollment solicitations.

Eligible  Employee  Benefit Plans.  The table of sales charges in the Prospectus
applies to sales to "eligible  employee benefit plans," except that the Fund may
sell shares at net asset value to "eligible  employee  benefit plans" which have
at least (1) $500,000  invested in the Seligman  Group of mutual funds or (2) 50
eligible employees to whom such plan is made available.  Such sales must be made
in connection with a payroll  deduction  system of plan funding or other systems
acceptable  to  Seligman  Data  Corp.,  the Fund's  shareholder  service  agent.
"Eligible  employee benefit plan" means any plan or arrangement,  whether or not
tax qualified,  which provides for the purchase of Fund shares.  Sales of shares
to such plans must be made in connection with a payroll deduction system of plan
funding or other system acceptable to Seligman Data Corp.

Such  sales are  believed  to require  limited  sales  effort and  sales-related
expenses and  therefore  are made at net asset value.  Contributions  or account
information for plan  participation  also should be transmitted to Seligman Data
Corp.  by methods  which it  accepts.  Additional  information  about  "eligible
employee  benefit  plans" is  available  from  financial  advisors  or  Seligman
Advisors.

Further  Types of  Reductions.  Class A shares  may also be  issued  without  an
initial sales charge to any registered unit investment trust which is the issuer
of periodic payment plan certificates, the net proceeds of which are invested in
Fund shares;  to separate  accounts  established  and maintained by an insurance
company which are exempt from  registration  under Section  3(c)(11) of the 1940
Act; to registered  representatives  and employees  (and their spouses and minor
children) of any dealer that has a sales  agreement with Seligman  Advisors;  to
financial  institution  trust  departments;  to registered  investment  advisers
exercising  discretionary  investment  authority with respect to the purchase of
Fund shares; to accounts of financial institutions or broker/dealers that charge
account management fees,  provided Seligman or one of its affiliates has entered
into  an  agreement  with  respect  to  such  accounts;  pursuant  to  sponsored
arrangements with organizations  which make  recommendations to, or permit group
solicitations of, its employees,  members or participants in connection with the
purchase of shares of the Fund;  to other  investment  companies in the Seligman
Group in connection with a deferred fee arrangement for outside  directors;  and
to "eligible  employee benefit plans" which have at least (1) $500,000  invested
in the Seligman  mutual funds or (2) 50 eligible  employees to whom such plan is
made available.

Class B

Class B shares may be  purchased  at a price  equal to the next  determined  net
asset  value,  without  an initial  sales  charge.  However,  Class B shares are
subject to a CDSC if the shares are  redeemed  within six years of  purchase  at
rates set forth in the table below,  charged as a percentage  of the current net
asset value or the original purchase price, whichever is less.

Years Since Purchase                                         CDSC
- --------------------                                         ----

4 years or more but less than 5 years .....................   2%
5 years or more but less than 6 years .....................   1%
6 years or more ...........................................   0%

Class D

Class D shares may be  purchased  at a price  equal to the next  determined  net
asset  value,  without  an initial  sales  charge.  However,  Class D shares are
subject to a CDSC of 1% if the shares are redeemed  within one year of purchase,
charged as a percentage of the current net asset value or the original  purchase
price, whichever is less.

Systematic Withdrawals. Class B and Class D shareholders who reinvest both their
dividends and capital gain  distributions to purchase  additional  shares of the
Fund, may use the Fund's  Systematic  Withdrawal  Plan to withdraw up to 12% and
10%,  respectively,  of the  value  of  their  accounts  per  year  without  the
imposition of a CDSC.  Account value is determined as of the date the systematic
withdrawals begin.

CDSC  Waivers.  The CDSC on  Class B and  Class D shares  (and  certain  Class A
shares,  as  discussed  above)  will  be  waived  or  reduced  in the  following
instances:

(1)  on  redemptions  following the death or  disability  (as defined in Section
     72(m)(7) of the  Internal  Revenue  Code) of a  shareholder  or  beneficial
     owner;

(2)  in connection with (1) distributions  from retirement plans qualified under
     Section  401(a) of the  Internal  Revenue  Code when such  redemptions  are
     necessary  to  make  distributions  to  plan  participants  (such  payments
     include,  but  are  not  limited  to,  death,  disability,  retirement,  or
     separation of service),  (2)  distributions  from a custodial account under
     Section  403(b)(7)  of the  Internal  Revenue  Code or an IRA due to death,
     disability,  minimum  distribution  requirements after attainment of age 70
     1/2 or, for accounts  established  prior to January 1, 1998,  attainment of
     age 59 1/2, and (3) a tax-free return of an excess contribution to an IRA;

(3)  in whole or in part, in connection  with shares sold to current and retired
     Directors of the Fund;

(4)  in whole or in part, in connection  with shares sold to any state,  county,
     or city or any instrumentality,  department,  authority, or agency thereof,
     which is prohibited by applicable  investment laws from paying a sales load
     or commission in connection with the purchase of any registered  investment
     management company;

(5)  in whole or in part, in connection with systematic withdrawals;

(6)  in connection with  participation  in the Merrill Lynch Small Market 401(k)
     Program.

<PAGE>

If, with respect to a redemption of any Class A, Class B, or Class D shares sold
by a dealer, the CDSC is waived because the redemption qualifies for a waiver as
set forth  above,  the dealer  shall remit to Seligman  Advisors  promptly  upon
notice,  an amount  equal to the  payment  or a portion of the  payment  made by
Seligman Advisors at the time of sale of such shares.

Fund Reorganizations

Class A shares may be issued without an initial sales charge in connection  with
the acquisition of cash and securities owned by other investment companies.  Any
CDSC will be waived in connection  with the  redemption of shares of the Fund if
the Fund is combined with another  Seligman mutual fund, or in connection with a
similar reorganization transaction.

Payment in Securities.  In addition to cash,  the Fund may accept  securities in
payment for Fund shares sold at the applicable  public offering price (net asset
value  and,  if  applicable,  any  sales  charge),  although  the Fund  does not
presently intend to accept securities in payment for Fund shares. Generally, the
Fund will only consider  accepting  securities (l) to increase its holdings in a
portfolio  security,  or (2) if Seligman  determines that the offered securities
are a suitable  investment for the Fund and in a sufficient amount for efficient
management.  Although no minimum has been  established,  it is expected that the
Fund would not accept securities with a value of less than $100,000 per issue in
payment  for  shares.  The Fund may reject in whole or in part offers to pay for
Fund shares with securities,  may require partial payment in cash for applicable
sales  charges,  and may  discontinue  accepting  securities as payment for Fund
shares  at any  time  without  notice.  The  Fund  will  not  accept  restricted
securities in payment for shares. The Fund will value accepted securities in the
manner provided for valuing portfolio securities of the Fund.

Offering Price

When you buy or sell fund shares, you do so at the Class's net asset value (NAV)
next calculated  after Seligman  Advisors  accepts your request.  Any applicable
sales charge will be added to the purchase price for Class A shares.

NAV per share of each class of the Fund is determined as of the close of regular
trading on the New York Stock Exchange  (normally,  4:00 p.m.  Eastern time), on
each day that the NYSE is open for business. The NYSE is currently closed on New
Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday,  Memorial
Day,  Independence Day, Labor Day, Thanksgiving Day, and Christmas Day. The Fund
will  also  determine  NAV for  each  class  on each  day in  which  there  is a
sufficient degree of trading in the Fund's portfolio  securities that the NAV of
Fund shares might be materially affected.  NAV per share for a class is computed
by dividing such class's share of the value of the net assets of the Fund (i.e.,
the value of its assets less  liabilities)  by the total  number of  outstanding
shares of such class.  All expenses of the Fund,  including the management  fee,
are accrued daily and taken into account for the purpose of determining NAV. The
NAV of Class B and Class D shares will  generally be lower than the NAV of Class
A shares as a result of the higher 12b-1 fees with respect to such shares.

Portfolio  securities,  including open short positions and options written,  are
valued at the last sale price on the securities exchange or securities market on
which such securities primarily are traded. Securities not listed on an exchange
or securities  market,  or securities in which there were no  transactions,  are
valued at the average of the most recent bid and asked price, except in the case
of open short  positions  where the asked price is available.  Any securities or
other assets for which recent market  quotations  are not readily  available are
valued at fair value as determined in accordance with procedures approved by the
Board of Directors.  Short-term  obligations with less than sixty days remaining
to maturity are generally valued at amortized cost. Short-term  obligations with
more than sixty days  remaining  to  maturity  will be valued at current  market
value until the sixtieth  day prior to  maturity,  and will then be valued on an
amortized cost basis based on the value on such date unless the Board determines
that this amortized  cost value does not represent  fair market value.  Expenses
and fees,  including the investment  management fee, are accrued daily and taken
into account for the purpose of determining the net asset value of Fund shares.


                                       20
<PAGE>

Generally,  trading in foreign securities,  as well as US Government securities,
money market instruments and repurchase agreements,  is substantially  completed
each day at  various  times  prior to the close of the NYSE.  The values of such
securities  used in computing  the net asset value of the shares of the Fund are
determined as of such times.  Foreign currency exchange rates are also generally
determined prior to the close of the NYSE.

For  purposes  of  determining  the net asset  value per share of the Fund,  all
assets  and  liabilities  initially  expressed  in  foreign  currencies  will be
converted  into US dollars at the mean  between the bid and offer prices of such
currencies  against  US  dollars  quoted  by a  major  bank  that  is a  regular
participant in the foreign  exchange market or on the basis of a pricing service
that takes into account the quotes provided by a number of such major banks.

Specimen Price Make-Up

Under  the  current  distribution  arrangements  between  the Fund and  Seligman
Advisors,  Class A shares are sold with a maximum  initial sales charge of 4.75%
and Class B and Class D shares are sold at NAV(1).  Using  each  Class's  NAV at
September  30,  1998,  the  maximum  offering  price of the Fund's  shares is as
follows:

Class A
- -------
     Net asset value per share...................................  $12.44

     Maximum sales charge (4.75% of offering price)..............     .62
                                                                   ------

     Offering price to public....................................  $13.06
                                                                   ======

Class B
- -------
     Net asset value and offering price per share(1) ............  $11.66
                                                                   ======

Class D
- -------
     Net asset value and offering price per share(1) ............  $11.67
                                                                   ======
- --------------
(1)  Class B shares are  subject to a CDSC  declining  from 5% in the first year
     after purchase to 0% after six years.  Class D shares are subject to a CDSC
     of 1% on redemptions within one year of purchase.

Redemption in Kind

The  procedures  for selling Fund shares under  ordinary  circumstances  are set
forth in the Prospectus. In unusual circumstances,  payment may be postponed, or
the right of  redemption  postponed  for more than seven  days,  if the  orderly
liquidation  of  portfolio  securities  is  prevented  by  the  closing  of,  or
restricted  trading  on, the NYSE  during  periods of  emergency,  or such other
periods  as ordered by the  Securities  and  Exchange  Commission.  Under  these
circumstances, redemption proceeds may be made in securities. If payment is made
in securities,  a shareholder may incur brokerage  expenses in converting  these
securities to cash.

                              Taxation of the Fund

The Fund is  qualified  and  intends  to  continue  to  qualify  as a  regulated
investment  company under  Subchapter M of the Internal  Revenue Code.  For each
year so qualified,  the Fund will not be subject to federal  income taxes on its
net investment  income and capital gains,  if any,  realized  during any taxable
year,  which it distributes to its  shareholders,  provided that at least 90% of
its net investment  income and net short-term  capital gains are  distributed to
shareholders each year.

Dividends  from net  investment  income and  distributions  from net  short-term
capital gains are taxable as ordinary income to  shareholders,  whether received
in cash or reinvested in additional  shares. To the extent designated as derived
from the  Fund's  dividend  income  that  would be  eligible  for the  dividends


                                       21
<PAGE>

received deduction if the Fund 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 gains (i.e.,  the excess of net long-term  capital
gains over any net  short-term  losses) are taxable as long-term  capital  gain,
whether  received in cash or invested in  additional  shares,  regardless of how
long the shares  have been held by a  shareholder.  Such  distributions  are not
eligible for the dividends received deduction allowed to corporate shareholders.
Shareholders receiving  distributions in the form of additional shares issued by
the Fund 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.  Individual  shareholders generally will be
subject to federal tax on  distributions  of net capital gains at a maximum rate
of 20% if designated as derived from the Fund's capital gains from property held
for more than one year.
    

Any gain or loss  realized  upon a sale or redemption of shares in the Fund by a
shareholder  who is not a dealer in  securities  will  generally be treated as a
long-term  capital  gain or loss if the shares  have been held for more than one
year and otherwise as a short-term capital gain or loss. Individual shareholders
will be subject to federal  income tax on net capital gains at a maximum rate of
20% in  respect of shares  held for more than one year.  Net  capital  gain of a
corporate shareholder is taxed at the same rate as ordinary income.  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 realized will be treated as long-term  capital loss to the extent
that it offsets the long-term capital gain  distribution.  In addition,  no loss
will be  allowed  on the sale or other  disposition  of  shares  of the Fund if,
within a period  beginning  30 days before the date of such sale or  disposition
and  ending 30 days  after such date,  the  holder  acquires  (including  shares
acquired  through  dividend  reinvestment)  securities  that  are  substantially
identical to the shares of the Fund.

In  determining  gain or loss on shares  of the Fund that are sold or  exchanged
within 90 days after acquisition,  a shareholder generally will not be permitted
to  include  in the tax basis  attributable  to such  shares  the  sales  charge
incurred in acquiring such shares to the extent of any  subsequent  reduction of
the sales charge by reason of the Exchange or Reinstatement Privilege offered by
the Fund. Any sales charge not taken into account in  determining  the tax basis
of shares sold or exchanged  within 90 days after  acquisition  will be added to
the  shareholder's  tax basis in the shares acquired pursuant to the Exchange or
Reinstatement Privilege.

The Fund will  generally  be subject to an excise tax of 4% on the amount of any
income  or  capital  gains,  above  certain  permitted  levels,  distributed  to
shareholder  on a  basis  such  that  such  income  or gain  is not  taxable  to
shareholders  in the  calendar  year  in  which  it  was  earned  by  the  Fund.
Furthermore,  dividends  declared in October,  November or December,  payable to
shareholders  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 Fund and received
by each shareholder in December. Under this rule, therefore, shareholders may be
taxed in one year on dividends or distributions  actually received in January of
the following year.

Shareholders  are urged to consult their tax advisors  concerning  the effect of
federal income taxes in their individual circumstances.

Unless a shareholder includes a certified taxpayer identification number (social
security number for  individuals) on the account  application and certifies that
the  shareholder is not subject to backup  withholding,  the fund is required to
withhold  and remit to the US  Treasury  a portion  of  distributions  and other
reportable  payments to the shareholder.  The rate of backup withholding is 31%.
Shareholders should be aware that, under regulations promulgated by the Internal
Revenue Service, the Fund may be fined $50 annually for each account for which a
certified taxpayer identification number is not provided. In the event that such
a fine is  imposed,  the Fund may charge a service  fee of up to $50 that may be
deducted from the  shareholder's  account and offset  against any  undistributed
dividends  and capital gain  distributions.  The Fund also reserves the right to
close  any  account  which  does not have a  certified  taxpayer  identification
number.

Distribution of Securities

The Fund and Seligman  Advisors are parties to a  Distributing  Agreement  dated
January 1, 1993 under which  Seligman  Advisors acts as the exclusive  agent for
distribution  of shares of the Fund.  Seligman  Advisors  accepts orders for the
purchase of Fund shares, which are offered continuously.  As general distributor
of the Fund's  capital  stock,  Seligman  Advisors  allows  reallowances  to all
dealers  on  sales  of  Class  A  shares,  as  set  forth  above  under  "Dealer
Reallowances."  Seligman  Advisors  retains the balance of sales charges and any
CDSCs paid by investors.

   
Total sales charges paid by  shareholders  of Class A shares of the Fund for the
fiscal years ended  September 30, 1998,  1997 and 1996,  amounted to $1,040,233,
$1,825,779,  and  $6,222,709,  respectively,  of which $117,076,  $203,896,  and
$689,900, respectively, was retained by Seligman Advisors.
    

Compensation

   
Seligman  Advisors,  which is an  affiliated  person  of  Seligman,  which is an
affiliated  person of the Fund,  received the  following  commissions  and other
compensation from the Fund during its fiscal year ended September 30, 1998:

      Net Underwriting      Compensation on    
        Discounts and       Redemptions and
         Commissions          Repurchases
       (Class A Sales     (CDSC on Class A and     Brokerage       Other
      Charge Retained)     Class D Retained)      Commissions   Compensation(1)
      ----------------     ----------------       -----------   ---------------

          $117,076              $119,411              $0            $59,977


(1)  Seligman  Advisors  has sold its  rights to  collect  any CDSC  imposed  on
     redemptions of Class B shares to FEP Capital,  L.P., in connection  with an
     arrangement  with FEP Capital,  L.P. as discussed above under "12b-1 Plan."
     In connection with this  arrangement,  Seligman  Advisors receives payments
     from FEP  Capital,  L.P.  based on the value of Class B shares  sold.  Such
     payments received for fiscal year 1998 are reflected in the table.
    

Other Payments

Seligman  Advisors shall pay  broker/dealers,  from its own resources,  a fee on
purchases of Class A shares of  $1,000,000  or more (NAV sales),  calculated  as
follows:  1.00% of NAV sales up to but not  including  $2  million;  .80% of NAV
sales from $2 million up to but not including $3 million; .50% of NAV sales from
$3 million up to but not  including  $5  million;  and .25% of NAV sales from $5
million and above.  The calculation of the fee will be based on assets held by a
"single  person,"  including an individual,  members of a family unit comprising
husband, wife and minor children purchasing securities for their own account, or
a trustee or other fiduciary purchasing for a single fiduciary account or single
trust.  Purchases made by a trustee or other  fiduciary for a fiduciary  account
may not be  aggregated  purchases  made on  behalf  of any  other  fiduciary  or
individual account.

   
Seligman Advisors shall also pay broker/dealers,  from its own resources,  a fee
on assets of certain  investments in Class A shares of the Seligman mutual funds
participating  in an "eligible  employee  benefit plan" that are attributable to
the particular broker/dealer. The shares eligible for the fee are those on which
an initial sales charge was not paid because either the  participating  eligible
employee benefit plan has at least (1) $500,000  invested in the Seligman mutual
funds or (2) 50 eligible employees to whom such plan is made available.  Class A
shares  representing  only an initial  purchase of Seligman Cash Management Fund
are not eligible for the fee. Such shares will become  eligible for the fee once
they are exchanged for shares of another  Seligman  mutual fund.  The payment is
based on  cumulative  sales  for each Plan  during a single  calendar  year,  or
portion thereof.  The payment  schedule,  for each calendar year, 
    


                                       23
<PAGE>

   
is as follows:  1.00% of sales up to but not including $2 million; .80% of sales
from $2  million  up to but not  including  $3  million;  .50% of sales  from $3
million up to but not  including  $5 million;  and .25% of sales from $5 million
and above.
    

Seligman  Advisors may from time to time assist  dealers by, among other things,
providing  sales  literature  to, and  holding  informational  programs  for the
benefit  of,  dealers'  registered   representatives.   Dealers  may  limit  the
participation of registered  representatives in such  informational  programs by
means of sales  incentive  programs which may require the sale of minimum dollar
amounts of shares of Seligman mutual funds.  Seligman  Advisors may from time to
time pay a bonus or other  incentive to dealers that sell shares of the Seligman
mutual funds. In some instances, these bonuses or incentives may be offered only
to certain dealers which employ registered  representatives who have sold or may
sell a  significant  amount of shares of the Fund and/or  certain  other  mutual
funds managed by the Manager  during a specified  period of time.  Such bonus or
other  incentive  may take the form of payment  for travel  expenses,  including
lodging,  incurred  in  connection  with trips  taken by  qualifying  registered
representatives  and members of their  families to places  within or outside the
United States. The cost to Seligman Advisors of such promotional  activities and
payments  shall be  consistent  with the rules of the  National  Association  of
Securities Dealers, Inc., as then in effect.

                         Calculation of Performance Data

   
The average annual total returns for the Fund's Class A shares for the one-year,
five-year, and ten-year periods through September 30, 1998, were -25.08%, 9.12%,
and 14.31%, respectively. These returns were computed by subtracting the maximum
sales  charge of 4.75% of public  offering  price and  assuming  that all of the
dividends and distributions  paid by the Fund over the relevant time period were
reinvested.  It was then  assumed  that at the end of each  period,  the  entire
amount was  redeemed.  The average  annual total return was then  calculated  by
calculating  the annual rate  required  for the  initial  payment to grow to the
amount which would have been received upon such  redemption  (i.e.,  the average
annual  compound  rate of return).  Table A below  illustrates  the total return
(income and capital) on Class A shares of the Fund,  assuming all  dividends and
gain distributions are reinvested in additional taken in shares. It shows that a
$1,000 investment in Class A shares, assuming payment of the initial 4.75% sales
charge, made on September 30, 1988, had a value of $3,811 on September 30, 1998,
resulting in an aggregate total return of 281.09%.

The average  annual total returns for the Fund's Class B shares for the one-year
period  ended  September  30,  1998  and for the  period  from  April  22,  1996
(inception)  through September 30, 1998, were -25.45% and -2.99%,  respectively.
These returns were computed assuming that all dividends and  distributions  paid
by the Fund's Class B shares,  if any,  were  reinvested  over the relevant time
period.  It was then assumed that at the end of each period,  the entire  amount
was redeemed,  subtracting  the applicable  CDSC.  Table B illustrates the total
return  (income  and  capital)  on  Class B shares  of the  Fund,  assuming  all
dividends and gain  distributions are reinvested in additional  shares. It shows
that a $1,000  investment in Class B shares on April 22, 1996  (commencement  of
operations  of  Class B  shares)  had a value  of $929 on  September  30,  1998,
resulting in an aggregate total return of -7.14%.

The average  annual total returns for the Fund's Class D shares for the one-year
and five-year  periods  ended  September 30, 1998 and for the period from May 3,
1993 (inception)  through  September 30, 1998, were -22.64%,  9.12%, and 13.20%,
respectively. These returns were computed assuming that all of the dividends and
distributions  paid by the Fund's Class D shares,  if any, were  reinvested over
the relevant  time  period.  It was then assumed that at the end of each period,
the entire amount was redeemed, subtracting for the one year period the 1% CDSC,
if  applicable.  Table C  illustrates  the total return  (income and capital) on
Class D shares of the Fund,  assuming all dividends and gain  distributions  are
reinvested in additional  shares.  It shows that a $1,000  investment in Class D
shares made on May 3, 1993  (commencement of operations of Class D shares) had a
value of $1,957 on September 30, 1998, resulting in an aggregate total return of
95.68%.

The total returns and average annual total returns of Class A shares quoted from
time to time for periods  through June 1, 1992,  do not reflect the deduction of
12b-1  fees,  because  the 12b-1 Plan was  implemented  on that date.  The total
returns  and  average  annual  total  returns for Class A and Class D shares for
periods through  December 31, 1995 do not reflect the increased  management fee,
approved by shareholders on December 12, 1995, and effective on January 1, 1996.
These fees, if reflected, would reduce the performance quoted.

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

Seligman's  beginnings  date back to 1837, when Joseph  Seligman,  the oldest of
eight brothers,  arrived in the United States from Germany. He earned his living

Seligmans became successful merchants,  establishing businesses in the South and
East.

Backed by nearly thirty years of business  success - culminating  in the sale of
government  securities to help finance the Civil War -Joseph Seligman,  with his
brothers,  established the international  banking and investment firm of J. & W.

SELIGMAN -- TIMES CHANGE...VALUES ENDURE

J. & W. SELIGMAN & CO. INCORPORATED IS A FIRM WITH A LONG TRADITION OF
INVESTMENT EXPERTISE, OFFERING A BROAD ARRAY OF INVESTMENT CHOICES TO HELP
TODAY'S INVESTORS SEEK THEIR LONG-TERM FINANCIAL GOALS.

[picture omitted]

James, Jesse, and Joseph Seligman, 1870

TIMES CHANGE...

Established in 1864, Seligman's history of providing financial services has been
marked not by fanfare, but rather by a quiet and firm adherence to financial
prudence. While the world has changed dramatically in the 134 years since
Seligman first opened its doors, the firm has continued to offer its clients
high-quality investment solutions through changing times.

In the late 19th century, as the country grew, Seligman helped finance the
westward expansion of the railroads, the construction of the Panama Canal, and
the launching of urban transit systems. In the first part of the 20th century,
as America became an industrial power, the firm helped fund the growing capital
needs of the nascent automobile and steel industries.

With the formation of Tri-Continental Corporation in 1929 -- today, the nation's
largest diversified publicly-traded closed-end investment company -- Seligman
began shifting its emphasis from investment banking to investment management.
Despite the stock market crash and ensuing depression, Seligman was convinced of
the importance that investment companies could have in building wealth for
individual investors and began managing its first mutual fund in 1930.

In the decades that followed, Seligman has continued to offer forward-looking
investment solutions, including funds that focus on technology stocks, municipal
bonds, and international securities.

 ...VALUES ENDURE

Seligman is proud of its distinctive past and of the traditional values that
continue to shape the firm's business decisions and investment judgment. While
much has changed over the years, the firm's commitment to providing prudent
investment management that seeks to build wealth for clients over time is an
enduring value that will guide Seligman into the new millennium.

TO THE SHAREHOLDERS

For the 12 months ended September 30, 1998, Seligman Frontier Fund had a total
return of -21.32% based on the net asset value of Class A shares, outperforming
the -24.83% total return of the Russell 2000 Growth Index, which is its market
benchmark. The total return of its peer group, as measured by the Lipper Small
Cap Funds Average was -20.52%. A discussion with your Portfolio Manager
regarding the past 12 months begins on page 2.

Despite their often superior sales and earnings growth, attractive valuations,
and limited exposure to depressed foreign markets, small-capitalization growth
stocks fared poorly in the past year compared to large-capitalization growth
stocks. The primary reason for the poor returns in the sector was the Asian
financial crisis, which caused investors to seek the perceived safety and
liquidity of large-cap growth stocks. The situation for small caps further
deteriorated in the final months of the Fund's fiscal year as the Asian crisis
worsened, Japan's recession and banking problems deepened, Russia's economy
neared ruin, and Brazil encountered fiscal problems that threatened all of Latin
America. The quest for liquidity in these volatile financial markets further
exacerbated investors' flight to large caps.

Global financial disorder, while likely to continue for many months, may
ultimately have a positive impact on small-cap valuations. Widespread currency
devaluations and depressed demand for products in Asia, Latin America, and
Russia, has led to concern about the future earnings of large-cap multinational
companies. Ongoing uncertainty about business conditions may compel investors to
favor smaller domestic companies whose revenues typically have only modest
exposure to today's tumultuous overseas markets.

Meanwhile, small-cap valuations have dropped to levels last seen in 1990, just
before the most recent extended run-up in value. In the 12 months ended
September 30, the S&P 500 gained 9.0%, while the Russell 2000 Growth Index fell
by 24.83%. The last two times the Russell 2000 suffered comparable declines, in
1979 and in 1990, strong rallies in small-cap stock prices followed. We believe
that the present low valuations and relatively positive earnings prospects of
small caps improve the potential for outperformance relative to large caps,
especially in light of the possibility that large caps may experience further
earnings pressure in the coming months.

As you may know, companies are modifying their computer systems to recognize
dates of January 1, 2000, and beyond. This is often referred to as the "Y2K"
problem. Unless systems are updated, many applications may interpret the last
two digits of the year to mean 1900 instead of 2000. J. & W. Seligman & Co.
Incorporated, the Seligman Investment Companies, and Seligman Data Corp., your

INTERVIEW WITH YOUR PORTFOLIO MANAGER,
ARSEN MRAKOVCIC

Q.  HOW DID SELIGMAN FRONTIER FUND PERFORM IN THE PAST 12 MONTHS?

A.  For the 12 months ended September 30, 1998, Seligman Frontier Fund posted a
    total return of -21.32% based on the net asset value of Class A shares. The
    Fund outperformed the -24.83% return of the Russell 2000 Growth Index, its
    market benchmark. The Fund's return lagged the -20.52% total return of its
    peers, as measured by the Lipper Small Cap Funds Average.

Q.  WHICH ECONOMIC AND MARKET FACTORS INFLUENCED SELIGMAN FRONTIER FUND IN THE
    PAST 12 MONTHS?

A.  Small-capitalization growth stocks continued to underperform
    large-capitalization growth stocks during the period, stretching the gradual
    price decline to three and one-half years. The decline in small-cap stock
    prices persisted, despite their attractive valuations relative to their
    growth rates.

    Despite ongoing strength in the domestic economy, economic turmoil began to
    spread throughout the world during the past 12 months, increasing investor
    concern in the US equity markets. The Asian financial crisis worsened, Japan
    again failed to resolve its banking problems, Russia allowed the ruble to
    devalue and subsequently defaulted on many of its debts, emerging markets
    collapsed, and the specter of economic crises looming throughout Latin
    America pressured equity markets worldwide. These factors prompted a
    so-called "flight to quality," in which many domestic and overseas investors
    sought the perceived safety and liquidity of large-cap growth stocks, often
    at the expense of small-cap stocks. As the US stock market was shaken by
    volatility in the final quarter of the Fund's fiscal year, the situation for
    small-cap stocks further deteriorated. Small caps were also hurt by
    continuing heavy volumes of initial public offering (IPO) activity,
    resulting in an oversupply of small-cap stocks in the market.

Q.  WHAT WAS YOUR INVESTMENT STRATEGY DURING THE YEAR?

A.  We are long-term investors who purchase small- capitalization growth stocks
    with significant earnings growth potential, and that are selling at
    reasonable cash flow valuations. Holdings are added to the portfolio based
    on their individual merits, on a stock-by-stock basis.

    We analyze the underlying fundamentals of companies, and prefer those with
    strong management, solid product lines, market niche dominance, proprietary
    and innovative products, and significant management ownership. Additionally,
    we favor companies with revenues and reported earnings growth of 20% or
    more, and with businesses and market shares that are growing faster than the

A TEAM APPROACH

Seligman Frontier Fund is managed by the Seligman Small Company Team, headed by
Arsen Mrakovcic. Mr. Mrakovcic is assisted in the management of the Fund by a
group of seasoned research professionals who are responsible for identifying
small companies in specific industry groups that offer the greatest potential
for growth.

    industry norm. We prefer companies that generate operating cash flow to
    finance growth over those which rely on excessive debt.

    We choose to sell stocks when they reach our target price, or when the
    company or industry fundamentals deteriorate. Seligman Frontier Fund remains
    highly diversified in order to reduce sector risk. No sector has a weighting
    of more than 25%, and no single stock represents more than 3% of the Fund's
    net assets.

Q.  WHAT INDUSTRY GROUPS INFLUENCED THE FUND'S PERFORMANCE?

A.  In an environment of global economic uncertainty and equity market
    volatility, defensive stocks lived up to their name. Consumer noncyclical
    stocks, such as Duane Reade, also did well. Health care stocks also were a
    profitable part of the portfolio. Several stocks in the pharmaceuticals
    sector outperformed expectations, as did some holdings in the consumer
    staples sector, such as U.S. Foodservice, a provider to the food service
    industry. Additionally, information technology services companies posted
    solid results for the 12-month period. These included BISYS Group, a
    supplier of data processing services; American Management Systems, which
    furnishes management and administration of computer services; and Ceridian,
    which provides data processing services.

    Further, a number of companies in the portfolio were acquired by larger
    companies during the 12-month period. Mergers and acquisitions activity
    demonstrates that the private market recognizes the quality of these
    companies, and the value of their stocks. These companies included R.P.
    Scherer, which manufactures soft gelatin capsules ("softgels"), and
    AmeriSource Health, a distributor of pharmaceutical supplies. As a result of
    mergers activity, these companies posted strong performances, benefiting the
    Fund.

    The basic materials sector is generally more sensitive to global economic
    conditions, and did not do well in the 12-month period. The capital goods,
    financial services, and transportation sectors also underperformed our
    expectations, mainly due to stock selection in each sector. In the capital
    goods sector, UCAR International, a producer of graphite electrodes,
    affected the portfolio's performance due to the company's unresolved
    antitrust issues. In the financial services sector, CCA Prison Realty Trust,
    a real estate investment trust for prisons, underperformed expectations
    because of concerns about slowing growth in the prison-building industry.

    Additionally, within the portfolio, there were poor performers even in
    strong industry sectors. Health care company ESC Medical Systems develops
    and manufactures medical devices for non-invasive, elective treatment of
    varicose veins. The stock suffered because of depressed demand, as
    discretionary procedures generally are more sensitive to economic
    conditions. In the business goods and services sector, Modis Professional
    Services, formerly AccuStaff, a provider of temporary personnel services,
    also underperformed expectations because of nationwide high levels of
    employment. In the educational services sector, EduTrek International,
    operator of the American Intercontinental University, also dampened the
    portfolio's performance.

Q.  WHAT IS YOUR OUTLOOK?

A.  History gives us reason for optimism. Despite the recent broad market
    downturn, which caused the S&P 500 to fall 14.1% from its peak on July 17,
    the S&P 500 was still up 9.0% in the past 12 months. However, the Russell
    2000 Index dropped 19.02% in this period, and the Russell 2000 Growth Index
    fell 24.83%. This wide gap in performance between the S&P 500 and the
    Russell 2000 Indices suggests that small caps are attractively valued
    compared to the large-cap growth stocks of the S&P 500. At current
    valuations, small caps should provide an attractive alternative to large
    caps, which have high price-to-earnings ratios. In fact, small-cap

PERFORMANCE OVERVIEW

   This chart compares a $10,000 hypothetical investment made in Seligman
Frontier Fund Class A shares, with and without the initial 4.75% maximum sales
charge, and assumes that all distributions within the period are invested in
additional shares, for the 10-year period ended September 30, 1998, to a $10,000
investment made in the Lipper Small Cap Funds Average (Lipper Average), the
Lipper Small Cap Fund Index (Lipper Index), the Russell 2000 Growth Index, and
the Russell 2000 Index for the same period. The performances of Seligman
Frontier Fund Class B and Class D shares are not shown in this chart but are
included in the table on page 5. It is important to keep in mind that the Lipper
Average and the Lipper Index exclude the effect of sales charges, and the
Russell indices exclude the effect of any fees or sales charges.

   Seligman Frontier Fund will no longer be compared to the Lipper Index after
September 30, 1998. Instead, the Fund will be compared to the Lipper Average,
which measures the performance of the entire universe of funds that have similar
investment objectives to your Fund. The Manager believes that the Lipper Average
is more appropriate than the more narrowly focused Lipper Index, which measures
the performance of only 30 funds. Therefore, going forward, your Fund will be
compared to the Lipper Average, the Russell 2000 Growth Index, and the Russell
2000 Index.

   Performance data quoted represent changes in prices and assume that all
distributions within the periods are invested in additional shares. The rates of
return will vary and the principal value of an investment will fluctuate.
Shares, if redeemed, may be worth more or less than their original cost. Past
performance is not indicative of future investment results.

- ----------
  * Returns for periods of less than one year are not annualized.
 ** Return figures reflect any change in price per share and assume the
    investment of dividends and capital gain distributions. Returns for Class A
    shares are calculated with and without the effect of the initial 4.75%
    maximum sales charge. Returns for Class A shares also reflect the effect of
    the service fee of up to 0.25% under the Administration, Shareholder
    Services and Distribution (12b-1) Plan after June 1, 1992, only. Returns for
    Class B shares are calculated with and without the effect of the maximum 5%
    contingent deferred sales charge ("CDSC"), charged on redemptions made
    within one year of the date of purchase, declining to 1% in the sixth year
    and 0% thereafter. Returns for Class D shares are calculated with and
    without the effect of the 1% CDSC, charged on redemptions made within one
    year of the date of purchase.
*** The Lipper Average, the Lipper Index, the Russell 2000 Growth Index, and the
    Russell 2000 Index are unmanaged benchmarks that assume investment of all
    dividends. The Lipper Average and Index do not reflect sales charges, and
    the Russell 2000 Growth Index and the Russell 2000 Index do not reflect fees
    and sales charges. The monthly performance of the Lipper Average is used in
    the Performance Overview. Investors cannot invest directly in an average or
    an index.

INTERVIEW WITH YOUR PORTFOLIO MANAGER,
ARSEN MRAKOVCIC (CONTINUED)

    valuations have fallen to levels not seen since 1990, just before the
    beginning of their last extended increase in price. The last two times the
    Russell 2000 was down 30% from its highs, in 1979 and in 1990, strong
    rallies followed.

    Small-cap companies are generally distinguished by the type of innovation
    that drives economic growth in this country. Smaller companies tend to
    possess internal management dynamics and product cycles that can weather
    economic turmoil and fickle financial markets. Further, smaller companies
    can, to a greater degree than larger companies, control their own destiny,
    irrespective of overall economic conditions. We are confident that the
    valuations and earnings prospects of small-cap stocks are favorable,
    especially in light of the possibility that large caps may experience
    earnings pressure in the coming months.

    We believe the case is strong for an impending appreciation in the price of
    small-cap stocks. Global financial disorder is likely to persist for many
    months, and could have less of a negative impact on small caps than on large
    caps. The strong dollar, widespread currency devaluations, and depressed
    demand for products in Asia, Latin America, and Russia has led to
    uncertainty about future earnings of large-cap multinational companies that
    do business in these regions. However, most small-cap growth companies have
    little exposure to depressed overseas markets, and they do not compete
    against local firms for market share. The earnings growth of a majority of
    US small caps is dependent to a great degree on the viability of their
    innovative products and their product cycles, and reflects their ability to
    execute their business plans. Overall, small-cap companies are less
    dependent on global economic conditions than are large-cap companies.

    The Federal Reserve Board's September and October cuts in short-term
    interest rates may benefit long-duration investments such as small-cap
    stocks. The rate reductions were done to temper inflation and sustain
    domestic economic growth, and to help cushion the US economy from global
    financial turmoil. Since the revenues of smaller companies are primarily
    linked to the strength of the domestic economy, an interest-rate cut may
    improve their earnings. Finally, the IPO market has slowed significantly,
    since the pricing of recent new issues was soft, and after-market
    performance was poor. Lower volumes of IPOs could help the performances of
    existing small-cap stocks.

NOTES TO FINANCIAL STATEMENTS

1. MULTIPLE CLASSES OF SHARES -- Seligman Frontier Fund, Inc. (the "Fund")
offers three classes of shares. Class A shares are sold with an initial sales
charge of up to 4.75% and a continuing service fee of up to 0.25% on an annual
basis. Class A shares purchased in an amount of $1,000,000 or more are sold
without an initial sales charge but are subject to a contingent deferred sales
charge ("CDSC") of 1% on redemptions within 18 months of purchase. Class B
shares are sold without an initial sales charge but are subject to a
distribution fee of 0.75%, and a service fee of up to 0.25% on an annual basis,
and a CDSC, if applicable, of 5% on redemptions in the first year of purchase,
declining to 1% in the sixth year and 0% thereafter. Class B shares will
automatically convert to Class A shares on the last day of the month that
precedes the eighth anniversary of their date of purchase. Class D shares are
sold without an initial sales charge but are subject to a distribution fee of up
to 0.75%, and a service fee of up to 0.25% on an annual basis, and a CDSC, if
applicable, of 1% imposed on redemptions made within one year of purchase. The
three classes of shares represent interests in the same portfolio of
investments, have the same rights and are generally identical in all respects
except that each class bears its separate distribution and certain other class
expenses, and has exclusive voting rights with respect to any matter on which a
separate vote of any class is required.

2. SIGNIFICANT ACCOUNTING POLICIES -- The financial statements have been
prepared in conformity with generally accepted accounting principles which
require management to make certain estimates and assumptions at the date of the
financial statements. The following summarizes the significant accounting
policies of the Fund:

a. SECURITY VALUATION -- Investments in stocks are valued at current market
   values or, in their absence, at fair values determined in accordance with
   procedures approved by the Board of Directors. Securities traded on national
   exchanges are valued at last sales prices or, in their absence and in the
   case of over-the-counter securities, at the mean of bid and asked prices.
   Short-term holdings maturing in 60 days or less are valued at amortized cost.

b. FEDERAL TAXES -- There is no provision for federal income tax. The Fund has
   elected to be taxed as a regulated investment company and intends to
   distribute substantially all taxable net income and net gain realized.

c. SECURITY TRANSACTIONS AND RELATED INVESTMENT INCOME -- Investment
   transactions are recorded on trade dates. Identified cost of investments sold
   is used for both financial statement and federal income tax purposes.
   Dividends receivable and payable are recorded on ex-dividend dates. Interest
   income is recorded on an accrual basis.

d. MULTIPLE CLASS ALLOCATIONS -- All income, expenses (other than class-specific
   expenses), and realized and unrealized gains or losses are allocated daily to
   each class of shares based upon the relative value of the shares of each
   class. Class-specific expenses, which include distribution and service fees
   and any other items that are specifically attributable to a particular class,
   are charged directly to such class. For the year ended September 30, 1998,
   distribution and service fees were the only class-specific expenses.

e. DISTRIBUTIONS TO SHAREHOLDERS -- The treatment for financial statement
   purposes of distributions made to shareholders during the year from net
   investment income or net realized gains may differ from their ultimate
   treatment for federal income tax purposes. These differences are caused
   primarily by differences in the timing of the recognition of certain
   components of income, expense, or realized capital gain for federal income
   tax purposes. Where such differences are permanent in nature, they are
   reclassified in the components of net assets based on their ultimate
   characterization for federal income tax purposes. For the year ended
   September 30, 1998, permanent differences aggregating approximately $13
   million have been reclassified from accumulated net investment loss and
   undistributed net realized gain to additional paid-in capital. These
   reclassifications will have no effect on net assets, results of operations,
   or net asset value per share of the Fund.

     For the year ended September 30, 1998, the Fund redeemed 57,121,361 of its
   shares from shareholders aggregating $848,070,114, of which approximately
   $2,200,000 represents capital gain distributions. This information is
   provided for federal income tax purposes only.

3. PURCHASES AND SALES OF SECURITIES -- Purchases and sales of portfolio
securities, excluding US Government obligations and short-term investments, for
the year ended September 30, 1998, amounted to $757,185,252 and $874,511,926,
respectively.

NOTES TO FINANCIAL STATEMENTS

   At September 30, 1998, the cost of investments for federal income tax
purposes was substantially the same as the cost for financial reporting
purposes, and the tax basis gross unrealized appreciation and depreciation of
portfolio securities amounted to $89,766,901 and $113,595,579 respectively.

4. MANAGEMENT FEE, DISTRIBUTION SERVICES, AND OTHER TRANSACTIONS -- J. & W.
Seligman & Co. Incorporated (the "Manager") manages the affairs of the Fund and
provides the necessary personnel and facilities. Compensation of all officers of
the Fund, all directors of the Fund who are employees or consultants of the
Manager, and all personnel of the Fund and the Manager, is paid by the Manager.
The Manager receives a fee, calculated daily and payable monthly, equal to 0.95%
per annum of the first $750 million of the Fund's average daily net assets and
0.85% per annum of the Fund's average daily net assets in excess of $750
million. The management fee reflected in the Statement of Operations represents
0.93% per annum of the Fund's average daily net assets.

   Seligman Advisors, Inc. (the "Distributor") (formerly Seligman Financial
Services, Inc.), agent for the distribution of the Fund's shares and an
affiliate of the Manager, received concessions of $117,076 from sales of Class A
shares after commissions of $923,157 were paid to dealers.

   The Fund has an Administration, Shareholder Services and Distribution Plan
(the "Plan") with respect to distribution of its shares. Under the Plan, with
respect to Class A shares, service organizations can enter into agreements with
the Distributor and receive a continuing fee of up to 0.25% on an annual basis,
payable quarterly, of average daily net assets of Class A shares attributable to
the particular service organizations for providing personal services and/or the
maintenance of shareholder accounts. The Distributor charges such fees to the
Fund pursuant to the Plan. For the year ended September 30, 1998, fees incurred
under the Plan aggregated $1,175,841, or 0.23% per annum of average daily net
assets of Class A shares.

   Under the Plan, with respect to Class B and Class D shares, service
organizations can enter into agreements with the Distributor and receive a
continuing fee for providing personal services and/or the maintenance of
shareholder accounts of up to 0.25% on an annual basis of the average daily net
assets of the Class B and Class D shares for which the organizations are
responsible; and, for Class D shares only, fees for providing other distribution
assistance of up to 0.75% on an annual basis of such average daily net assets.
Such fees are paid monthly by the Fund to the Distributor pursuant to the Plan.

   With respect to Class B shares, a distribution fee of 0.75% on an annual
basis of average daily net assets is payable monthly by the Fund to the
Distributor; however, the Distributor has sold its rights to substantially all
of this fee to a third party (the "Purchaser"), which provides funding to the
Distributor to enable it to pay commissions to dealers at the time of the sale
of the related Class B shares.

   For the year ended September 30, 1998, fees incurred under the Plan,
equivalent to 1% per annum of the average daily net assets of Class B and Class
D shares, amounted to $796,405 and $3,588,957, respectively.

   The Distributor is entitled to retain any CDSC imposed on redemptions of
Class D shares occurring within one year of purchase and on certain redemptions
of Class A shares occurring within 18 months of purchase. For the year ended
September 30, 1998, such charges amounted to $119,411.

   The Distributor has sold its rights to collect any CDSC imposed on
redemptions of Class B shares to the Purchaser. In connection with the sale of
its rights to collect any CDSC and the distribution fees with respect to Class B
shares described above, the Distributor receives payments from the Purchaser
based on the value of Class B shares sold. The aggregate amount of such payments
and the Class B shares' distribution fees retained by the Distributor, for the
year ended September 30, 1998, amounted to $59,977.

   Seligman Services, Inc., an affiliate of the Manager, is eligible to receive
commissions from certain sales of shares of the Fund, as well as distribution
and service fees pursuant to the Plan. For the year ended September 30, 1998,
Seligman Services, Inc. received commissions of $14,982 from the sale of shares
of the Fund. Seligman Services, Inc. also received distribution and service fees
of $87,176, pursuant to the Plan.

   Seligman Data Corp., which is owned by certain associated investment
companies, charged the Fund at cost $2,105,436 for shareholder account services.

   Certain officers and directors of the Fund are officers or directors of the
Manager, the Distributor, Seligman Services, Inc., and/or Seligman Data Corp.

NOTES TO FINANCIAL STATEMENTS

   The Fund has a compensation arrangement under which directors who receive
fees may elect to defer receiving such fees. Directors may elect to have their
deferred fees accrue interest or earn a return based on the performance of the
Fund or other funds in the Seligman Group of Investment Companies. The cost of
such fees and earnings accrued thereon is included in directors' fees and
expenses, and the accumulated balance thereof at September 30, 1998, of $49,317
is included in other liabilities. Deferred fees and related accrued earnings are
not deductible for federal income tax purposes until such amounts are paid.

5. COMMITTED LINE OF CREDIT -- Effective July 1, 1998, the Fund terminated its
$78 million committed line of credit and entered into a joint $800 million
committed line of credit that is shared by substantially all funds in the
Seligman Group of Investment Companies. The Fund's borrowings are limited to 10%
of its net assets. Borrowings pursuant to the credit facility are subject to
interest at a rate equal to the overnight federal funds rate plus 0.50% on an
overnight basis. The Fund incurs a commitment fee of 0.08% per annum on its
share of the unused portion of the credit facility. The credit facility may be
drawn upon only for temporary purposes and is subject to certain other customary
restrictions. The credit facility commitment expires one year from the date of
the agreement but is renewable with the consent of the participating banks. To
date, the Fund has not borrowed from the credit facility.

6. AFFILIATED ISSUERS -- As defined under the Investment Company Act of 1940, as
amended, affiliated issuers are those issuers in which the Fund's holdings of an
issuer represent 5% or more of the outstanding voting securities of the issuer.
A summary of the Fund's transactions in the securities of these issuers during
the year ended September 30, 1998, is as follows:

FINANCIAL HIGHLIGHTS

   The Fund's financial highlights are presented below. "Per share operating
performance" data is designed to allow investors to trace the operating
performance of eachClass, on a per share basis, from the beginning net asset
value to the ending net asset value, so that investors can understand what
effect the individual items have on their investment, assuming it was held
throughout the period. Generally, 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 share amounts, based on average shares
outstanding.

   "Total return based on net asset value" measures each Class's performance
assuming that investors purchased Fund shares at net asset value as of the
beginning of the period, invested dividends and capital gains paid at net asset
value, and then sold their shares at the net asset value on the last day of the
period. The total return computations do not reflect any sales charges investors
may incur in purchasing or selling shares of the Fund. Total returns for periods
of less than one year are not annualized.

REPORT OF INDEPENDENT AUDITORS

THE BOARD OF DIRECTORS AND SHAREHOLDERS,
SELIGMAN FRONTIER FUND, INC.:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of Seligman Frontier Fund, Inc. as of September
30, 1998, the related statements of operations for the year then ended and of
changes in net assets for each of the years in the two-year period then ended,
and the financial highlights for each of the periods presented. These financial
statements and financial highlights are the responsibility of the Fund's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audits. We conducted our audits
in accordance with generally accepted auditing standards. Those standards
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements and financial highlights are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. Our procedures included
confirmation of securities owned as of September 30, 1998, by correspondence
with the Fund's custodian and brokers; where replies were not received from
brokers we performed other auditing procedures. An audit also includes assessing
the accounting principles used and significant estimates made by management, as
well as evaluating the overall financial statement presentation. We believe that
our audits provide a reasonable basis for our opinion.

In our opinion, such financial statements and financial highlights present
fairly, in all material respects, the financial position of Seligman Frontier
Fund, Inc. as of September 30, 1998, the results of its operations, the changes
in its net assets, and the financial highlights for the respective stated
periods, in conformity with generally accepted accounting principles.

GLOSSARY OF FINANCIAL TERMS

CAPITAL GAIN DISTRIBUTION -- A payment to mutual fund shareholders of profits
realized on the sale of securities in a fund's portfolio. For tax purposes,
these profits may be taxed at different rates, primarily depending upon the
length of time the securities were owned by the fund.

CAPITAL APPRECIATION/DEPRECIATION -- An increase or decrease in the market value
of a mutual fund's portfolio securities, which is reflected in the net asset
value of the fund's shares. Capital appreciation/depreciation of an individual
security is in relation to the original purchase price.

COMPOUNDING -- The change in the value of an investment as shareholders receive
earnings on their investment's earnings. For example, if $1,000 is invested at a
fixed rate of 7% a year, the initial investment is worth $1,070 after one year.
If the return is compounded, second year earnings will not be based on the
original $1,000, but on the $1,070, which includes the first year's earnings.

CONTINGENT DEFERRED SALES CHARGE (CDSC) -- Depending on the class of shares
owned, a fee charged by a mutual fund when shares are sold back to the fund (the
CDSC expires after a fixed time period).

DIVIDEND -- A payment by a mutual fund, usually derived from the fund's net
investment income (dividends and interest less expenses).

DIVIDEND YIELD -- A measurement of a fund's dividend as a percentage of the
maximum offering price.

EXPENSE RATIO -- The cost of doing business for a mutual fund, expressed as a
percent of the fund's net assets.

INVESTMENT OBJECTIVE -- The shared investment goal of a fund and its
shareholders.

MANAGEMENT FEE -- The amount paid by a mutual fund to its investment advisor(s).

MULTIPLE CLASSES OF SHARES -- Although an individual mutual fund invests in only
one portfolio of securities, it may offer investors several purchase options
which are "classes" of shares. Multiple classes permit shareholders to choose
the fee structure that best meets their needs and goals. Generally, each class
will differ in terms of how and when sales charges and certain fees are
assessed.

NATIONAL ASSOCIATION OF SECURITIES DEALERS, INC. (NASD) -- A self-regulatory
body with authority over firms that distribute mutual funds.

NET ASSET VALUE (NAV) PER SHARE -- The market worth of one fund share, obtained
by adding a mutual fund's total assets (securities, cash, and any accrued
earnings), subtracting liabilities, and dividing the resulting net assets by the
number of shares outstanding.

OFFERING PRICE (OP) -- The price at which a mutual fund's share can be
purchased. The offering price per share is the current net asset value plus any
sales charge.

PORTFOLIO TURNOVER -- A measure of the trading activity in a mutual fund's
investment portfolio that reflects how often securities are bought and sold.

PROSPECTUS -- The legal document describing a mutual fund to all prospective
shareholders. It contains information required by the Securities and Exchange
Commission (SEC), such as a fund's investment objective and policies, services,
investment restrictions, officers and directors, how shares are bought and
redeemed, fund fees and other charges, and the fund's financial statements.

SEC YIELD -- SEC Yield refers to the net income earned by a fund during a recent
30-day period. This income is annualized and then divided by the maximum
offering price per share on the last day of the 30-day period. The SEC Yield
formula reflects semiannual compounding.

SECURITIES AND EXCHANGE COMMISSION -- The primary US federal agency that
regulates the registration and distribution of mutual fund shares.

STATEMENT OF ADDITIONAL INFORMATION -- A document that contains updated or more
detailed information about an investment company and that supplements the
prospectus. It is available at no charge upon request.

TOTAL RETURN -- A measure of a fund's performance encompassing all elements of
return. Reflects the change in share price over a given period and assumes all
distributions are taken in additional fund shares. The AVERAGE ANNUAL TOTAL
RETURN represents the average annual compounded rate of return for the periods
presented.

YIELD ON SECURITIES -- For bonds, the current yield is the coupon rate of
interest, divided by the purchase price. For stocks, the yield is measured by
dividing dividends paid by the market price of the stock.

Item 24. PERSONS CONTROLLED BY OR UNDER COMMON CONTROL WITH REGISTRANT - None.
- --------

Item 25. INDEMNIFICATION
- --------

         Reference is made to the provisions of Articles  Twelfth and Thirteenth
         of Registrant's Amended and Restated Articles of Incorporation filed as
         Exhibit  24(b)(1) and Article IV of  Registrant's  Amended and Restated
         By-laws  filed  as  Exhibit  24(b)(2)  to  Registrant's  Post-Effective
         Amendment No. 21 to the Registration Statement.

         Insofar as indemnification for liabilities arising under the Securities
         Act of 1933 may be permitted  to  directors,  officers and  controlling
         persons of the  registrant  pursuant to the  foregoing  provisions,  or
         otherwise,  the  registrant  has been  advised  by the  Securities  and
         Exchange  Commission such  indemnification  is against public policy as
         expressed in the Act as is, therefore, unenforceable. In the event that
         a claim for  indemnification  against such liabilities  (other than the
         payment by the  registrant of expenses  incurred or paid by a director,
         officer  or  controlling  person of the  registrant  in the  successful
         defense  of any  action,  suit  or  proceeding)  is  asserted  by  such
         director,   officer  or  controlling  person  in  connection  with  the
         securities being registered, the registrant will, unless in the opinion
         of its counsel the matter has been  settled by  controlling  precedent,
         submit to a court of appropriate jurisdiction the question whether such
         indemnification  by it is against public policy as expressed in the Act
         and will be governed by the final adjudication of such issue.

Item 26. BUSINESS AND OTHER CONNECTIONS OF INVESTMENT ADVISER - J. & W. Seligman
         &  Co.  Incorporated,   a  Delaware  corporation  ("Manager"),  is  the
         Registrant's  investment manager. The Manager also serves as investment
         manager to seventeen associated investment companies. They are Seligman

         by this Item 28 of officers and directors of the Manager, together with
         information  as  to  any  other  business,   profession,   vocation  or

                    DEFERRED COMPENSATION PLAN FOR DIRECTORS

                                       OF

                          SELIGMAN FRONTIER FUND, INC.
                                    ("FUND")


1.       ELECTION TO DEFER PAYMENTS. Any member of the Board of Directors
(herein, a "Director") of the Fund may elect to have payment of that Director's
annual retainer or meeting fees or both for Board service deferred as provided
in this Plan. The election shall be made in writing prior to, and to take effect
from, the beginning of a calendar year. For any Director in the year in which
this Plan is adopted or for a person elected a director in other than the last
calendar month of a year, the election shall be made within 30 days after that
event and prior to, and to take effect from, the beginning of the calendar
quarter next ensuing after that event. Elections shall continue in effect until
terminated in writing, any such termination to take effect on the first day of
the calendar year beginning after receipt of the notice of termination. An
election shall be irrevocable as to payments deferred in conformity with that
election.

2.       DEFERRED PAYMENT ACCOUNT. Each deferred retainer or fee shall be
credited at the time when it otherwise would have been payable to an account to
be established in the name of the Director on the books of the Fund (the
"Deferred Payment Account") adjusted for notional investment experience as
hereinafter described.

3.        RETURN ON DEFERRED PAYMENT ACCOUNT BALANCE. (a) For purposes of
measuring the investment return on his Deferred Payment Account, the Director
may elect to have the aggregate amount of his deferred compensation (or a
specified portion thereof) receive a return (i) at a rate equal to the return
earned on three-month U.S. Treasury Bills at the beginning of each calendar
quarter (the "Treasury Bill Rate") and such interest shall be credited to the
account quarterly at the end of each calendar quarter, or (ii) at a rate of
return (positive or negative) equal to the rate of return on the shares of any
of the registered investment companies managed by J. & W. Seligman & Co.
Incorporated ("Seligman") or any other entity controlling, controlled by, or
under common control with (as such terms are defined in the Investment Company
Act of 1940) Seligman (each, a "Notional Fund"), assuming reinvestment of
dividends and distributions from the Notional Funds. (b) A Director may amend
his designation of investment return as of the end of each calendar quarter by
giving written notice to the President of the Fund at least 30 days prior to the
end of such calendar quarter. A timely change to a Director's designation of
investment return shall become effective on the first day of the calendar
quarter following receipt by the President of the Fund (the "President").

4.       NOTIONAL INVESTMENT EXPERIENCE. Amounts credited to a Deferred Payment
Account shall be periodically adjusted for notional investment experience. In
each case such notional investment experience shall be determined by treating
the Deferred

<PAGE>

Payment Account as though an equivalent dollar amount had been invested and
reinvested in one or more of the Notional Funds. The Notional Funds used as a
basis for determining notional investment experience with respect to any
Director's Deferred Payment Account shall be designated by the Director in
writing by instrument of election substantially in the form attached hereto as
Exhibit C and may be changed prospectively by similar written election effective
as of the first day of any calendar quarter. The President may from time to time
limit the Notional Funds available for purposes of such election. If at any time
any Notional Fund that has previously been designated by a Director as a
notional investment shall cease to exist or shall be unavailable for any reason,
or if the Director fails to designate one or more Notional Funds pursuant to
this Section 4, the President may, at his discretion and upon notice to the
Director, treat any amounts notionally invested in such Notional Fund (whether
representing past amounts credited to a Director's Deferred Payment Account or
subsequent fee deferrals or both) as having been invested at the Treasury Bill
Rate, only until such time as the Director shall have made another investment
election in accordance with the foregoing procedures. Deferred Payment Accounts
shall continue to be adjusted for notional investment experience until
distributed in full in accordance with the distribution method elected by the
Director pursuant to Section 5 hereof.

5.       PAYMENT OF DEFERRED AMOUNTS. All amounts credited to an account
pursuant to any election by the Director made as provided in Section 1 hereof
shall be paid to the Director

         (a)      in, or beginning in, the calendar year following the calendar
                  year in which the Director ceases to be a Director of the
                  Fund, or

         (b)      in, or beginning in, the calendar year following the earlier
                  of the calendar year in which the Director ceases to be a
                  Director of the Fund or attains age 70,

                  and shall be paid

         (c)      in a lump sum payable on the first day of the calendar year in
                  which payment is to be made, or

         (d)      in 10 or fewer installments, payable on the first day of each
                  year commencing with the calendar year in which payment is to
                  begin, all as the Director shall specify in making the
                  election. If the payment is to be made in installments, the
                  amount of each installment shall be equal to a fraction of the
                  total of the amounts in the account at the date of the payment
                  the numerator of which shall be one and the denominator of
                  which shall be the then remaining number of unpaid
                  installments (including the installment then to be paid). If
                  the Director dies at any time before all amounts in the
                  account have been paid, such amounts shall be paid at that
                  time in a lump sum to the beneficiary or beneficiaries

<PAGE>

                  designated by the Director in writing to receive such payments
                  or in the absence of such a designation to the estate of the
                  Director.

The Board of Directors may, in the case of an unforseeable emergency, at its
sole discretion accelerate the payment of any unpaid amount for any or all
Directors. For purposes of this paragraph, an unforseeable emergency is severe
financial hardship to the Director resulting from a sudden and unexpected
illness or accident of the Director or of a dependent (as defined in section
152(a) of the Internal Revenue Code) of the Director, loss of the Director's
property due to casualty, or other similar extraordinary and unforseeable
circumstances arising as a result of events beyond the control of the Director.
Payment due to an unforseeable emergency may not be made to the extent that such
hardship is or may be relieved (i) through reimbursement or compensation by
insurance or otherwise; (ii) by liquidation of the Director's assets, to the
extent the liquidation of such assets would not itself cause severe financial
hardship, or (iii) by cessation of deferrals under the Plan. Examples of what
are not considered to be unforseeable emergencies include the need to send a
Director's child to college or the desire to purchase a home. Withdrawals of
amounts because of an unforseeable emergency are only permitted to the extent
reasonably necessary to satisfy the emergency need.

6.       ASSIGNMENT. No deferred amount or unpaid portion thereof may be
assigned or transferred by the Director except by will or the laws of descent
and distribution.

7.       WITHHOLDING TAXES. The Fund shall deduct from all payments any federal,
state or local taxes and other charges required by law to be withheld with
respect to such payments.

8.       NATURE OF RIGHTS; NONALIENATION. A Director's rights to deferred
payment under the Plan shall be solely those of an unsecured general creditor of
the Fund, and any payments by the Fund pursuant to the Plan will be made solely
from the Fund's general assets and property. The Fund will be under no
obligation to purchase, hold or dispose of any investment for the specific
benefit of any Director but, if the Fund should choose to purchase shares of any
Notional Fund in order to cover all or a portion of its obligations under the
Plan, then such investments will continue to be a part of the general assets and
property of the Fund. A Director's rights under the Plan may not be transferred,
assigned, pledged or otherwise alienated, and any attempt by the Director to do
so shall be null and void.

9.       STATUS OF DIRECTOR. Nothing in the Plan nor any election hereunder
shall be construed as conferring on any Director the right to remain a Director
of the Fund or to receive fees at any particular rate.

10.      AMENDMENT AND ACCELERATION. The Board of Directors may at any time at
its sole discretion amend or terminate this Plan, provided that no such
amendment or termination 

<PAGE>

shall adversely affect the right of Directors to receive deferred amounts
credited to their account.

11.      ADMINISTRATION. The Plan shall be administered by the President or by
such person or persons as the President may designate to carry out
administrative functions hereunder. The President shall have complete discretion
to interpret and administer the Plan in accordance with its terms, and his
determinations shall be binding on all persons.
