THE FUND

INVESTMENT OBJECTIVE/PRINCIPAL STRATEGIES

The Fund's objective is capital gain.

The Fund uses the following principal strategies to seek its objective:

The Fund invests at least 80% of its net assets, exclusive of government
securities, short-term notes, and cash and cash equivalents, in the securities
of companies operating in the communications, information and related
industries. The Fund generally invests at least 65% of its total assets in
securities of companies engaged in these industries. The Fund may invest in
securities of large companies that now are well established in the world
communications and information market and can be expected to grow with the
market. The Fund may also invest in small-to-medium size companies that the
investment manager believes provide opportunities to benefit from the rapidly
changing technologies and the expansion of the communications, information and
related industries. The Fund uses a bottom-up stock selection approach. This
means that the investment manager uses extensive in-depth research into specific
companies in the communications, information and related industries to find
those companies that it believes offer the greatest prospects for future growth.
In selecting individual securities, the investment manager looks for companies
that it believes display or are expected to display:

                        o Robust growth prospects
                        o High profit margins or return on capital
                        o Attractive valuation relative to expected earnings
                          or cash flow
                        o Quality management
                        o Unique competitive advantages

The Fund generally sells a stock if the investment manager believes its target
price has been reached, its earnings are disappointing, its revenue growth has
slowed, or its underlying fundamentals have deteriorated.

The Fund invests primarily in common stocks. However, the Fund may also invest
in securities convertible into or exchangeable for common stocks, in rights and
warrants to purchase common stocks, and in debt securities or preferred stocks
believed to provide opportunities for capital gain.

The Fund may purchase 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. The Fund may invest up to 15% of its
net assets in illiquid securities (i.e., securities that cannot be readily sold)
and may invest up to 10% of its total assets directly in foreign securities. The
limit on foreign securities does not include ADRs, or commercial paper and
certificates of deposit issued by foreign banks. The Fund may also purchase put
options in an attempt to hedge against a decline in the price of securities it
holds. A put option gives the Fund the right to sell an underlying security at a
particular price during a fixed period. The Fund may, from time to time, borrow
money to purchase securities.

The Fund may, from time to time, take temporary defensive positions that are
inconsistent with its principal strategies in seeking to minimize extreme
volatility caused by adverse market, economic, or other conditions. This could
prevent the Fund from achieving its objective.

The Fund may change its principal strategies if the Fund's Board of Directors
believes doing so is consistent with the Fund's objective. The Fund's objective
may be changed only with shareholder approval.

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


                                       1

<PAGE>
PRINCIPAL RISKS

Stock prices fluctuate. Therefore, as with any fund that invests in stocks, the
Fund's net asset value will fluctuate. You may experience a decline in the value
of your investment and you could lose money if you sell your shares at a price
lower than you paid for them.

The Fund concentrates its investments in companies in the communications,
information and related industries. Therefore, the Fund may be susceptible to
factors affecting these industries and the Fund's net asset value may fluctuate
more than a fund that invests in a wider range of industries. In addition, the
rapid pace of change within many of these industries tends to create a more
volatile operating environment than in other industries.

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

Foreign securities, illiquid securities, or options in the Fund's portfolio
involve higher risk and may subject the Fund to higher price volatility.
Investing in securities of foreign issuers involves risks not associated with US
investments, including settlement risks, currency fluctuations, foreign
taxation, differences in financial reporting practices, and changes in political
conditions.

The Fund may actively and frequently trade securities in its portfolio to carry
out its principal strategies. A high portfolio turnover rate increases
transaction costs which may increase the Fund's expenses. There may also be
adverse tax consequences for investors in the Fund due to an increase in
short-term capital gains.

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 four 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 the performance of
each Class (except Class C) compares to one widely-used measure of stock
performance, and one measure of the performance of mutual funds with investment
objectives similar to the Fund. Class C is a new class of shares, effective June
1, 1999, so no performance information is available.


The following performance information is designed 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.

                          CLASS A ANNUAL TOTAL RETURNS

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.

Example
- -------

This example is intended to help you compare the expenses of investing in the
Fund with the expenses of investing in other mutual funds. It assumes (1) you
invest $10,000 in the Fund for each period and then sell all of your shares at
the end of that period, (2) your investment has a 5% return each year, and (3)
the Fund's operating expenses remain the same. Although your actual expenses may
be higher or lower, based on these assumptions your expenses would be:


                      1 Year        3 Years      5 Years     10 Years
                       -----        -------      -------      -------
Class A                $615          $909        $1,225       $2,117
Class B                 722           985         1,375        2,334+
Class C                 420           778         1,263        2,598
Class D                 322           685         1,175        2,524

If you did not sell your shares at the end of each period, your expenses would
be:

MANAGEMENT

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

J. & W. Seligman & Co. Incorporated (Seligman), 100 Park Avenue, New York, New
York 10017, is the manager of the Fund. 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 USregistered
investment companies, which offer more than 50 investment portfolios with
approximately $21.5 billion in assets as of April 30, 1999. Seligman also
provides investment management or advice to institutional or other accounts
having an aggregate value at April 30, 1999, of approximately $10.2 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 .90% of the
Fund's average daily net assets on the first $3 billion of net assets, .85% of
the Fund's average daily net assets on the next $3 billion of net assets and
 .75% of the Fund's average daily net assets in excess of $6 billion. For the
year ended December 31, 1998, the management fee paid by the Fund to Seligman
was equal to .88% of the Fund's average daily net assets.

The Fund, certain of its current and former directors, and Seligman have been
named in a lawsuit filed in the United States District Court for the Northern
District of Maryland on February 5, 1999. The complaint makes various
allegations and claims relating to the February 1996 special meeting of the
Fund's shareholders at which an increase in the management fee rate payable to
Seligman by the Fund was approved. The Fund believes the claims to be without
merit and intends to defend the action vigorously.

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 team'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 2000 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 issuers, which, like other
organizations, are also susceptible to year 2000 concerns. Year 2000 issues may
affect an issuer's operations, creditworthiness, and ability to make timely
payment on any indebtedness and could have an adverse impact on the value of its
securities. If the 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 domestic or foreign exchanges, markets, depositories, clearing agencies, or
governments 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 its
ongoing 12b-1 fees may differ from other Classes. 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:

</TABLE>

      (1)"Offering Price" is the amount that you actually pay for Fund shares;
         it includes the initial sales charge.

      (2)Your purchase of Class C shares must be for less than $1,000,000
         because if you invest $1,000,000 or more you will pay less in fees and
         charges if you buy Class A shares.

   o  A 1% CDSC on shares sold within eighteen months of purchase.
   o  Annual 12b-1 fee (for distribution and shareholder services) of 1.00%.
   o  No automatic conversion to Class Ashares, so you will be subject
      to higher ongoing 12b-1 fees indefinitely.
   o  No CDSC when you sell shares purchased with reinvested dividends or
      capital gain distributions.
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
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 when you sell shares purchased with reinvested dividends or
      capital gain distributions.

      *Class D shares are not available to all investors. Beginning June 1,
      1999, you may purchase Class D shares only if (1) you already own Class D
      shares of the Fund or another Seligman mutual fund, (2) if your financial
      advisor of record maintains an omnibus account at SDC, or (3) pursuant
      to a 401(k) or other retirement plan program for which Class D shares are
      already available or for which the sponsor requests Class D shares because
      the sales charge structure of Class D shares is comparable to the sales
      charge structure of the other funds offered under the program.
- --------------------------------------------------------------------------------

Because the Fund's 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, Class C, 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 the 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' 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, it 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 and Class C
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.


- --------------------------------------------------------------------------------
NAV:
Computed separately for each Class by dividing that Class's share of the net
assets of the Fund (i.e., its assets less liabilities) by the total number of
outstanding shares of the Class.
- --------------------------------------------------------------------------------

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, Class C, and Class D shares will generally be lower than the NAV
of Class A shares of the Fund.

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.

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 or lower
minimum investments. Ask your financial advisor if any of these programs apply
to you. Class D shares are not available to all investors. For more information,
see "Deciding Which Class of Shares to Buy--Class D."


To make your initial investment in the Fund, contact your financial advisor or
complete an 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. The required
minimum initial investments are:

         o Regular (non-retirement) accounts: $2,500

         o For accounts opened concurrently with Invest-A-Check(R):
           $200 to open if you will be making monthly investments
           $500 to open if you will be making quarterly investments

- --------------------------------------------------------------------------------
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.
- --------------------------------------------------------------------------------

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 purchase, and any subsequent
transactions in your account. You will also be sent quarterly and annual
statements detailing your transactions in the Fund and the other Seligman funds
you own under the same account number. 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.

Subsequent investements must be for $100 or more. 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. Unless you indicate otherwise, your
investment will be made in the Class you already own. Send investment checks to:

                 Seligman Data Corp.
                 P.O. Box 9766
                 Providence, RI 02940-9766

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(R). 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 $200 or more, or regular quarterly intervals in fixed amounts
of $500 or more. If you use Invest-A-Check(R), 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, or Class C
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 AMONG 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 or
Class C shares of Seligman Cash Management Fund to buy shares of the same Class
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(R) 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). You should read and understand a fund's
prospectus before investing. Some funds may not offer all classes of shares.

HOW TO SELL SHARES

The easiest way to sell Fund shares is by phone. If you have telephone services,
you may be able 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 sell shares to the Fund through a broker/dealer or your financial
advisor. The Fund does not charge any fees or expenses, other than any
applicable CDSC, for this transaction; however, the dealer or financial advisor
may charge a service fee. Contact your financial advisor for more information.


You may always send a written request to sell Fund shares;  however, it may take
longer to get your money.

As an additional measure to protect you and the Fund, SDC may confirm written
redemption requests that are (1) for $25,000 or more, or (2) directed to be paid
to an alternate payee or sent to an address other than the address of record,
with you or your financial advisor by telephone before sending you your money.
This will not affect the date on which your redemption request is actually
processed.


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 dollar 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, Class C, or Class D
shares and reinvest your dividends and capital gain distributions, you may
withdraw 12%, 10%, or 10%, respectively, of the value of your Fund account (at
the time of election) annually without a CDSC.

IMPORTANT POLICIES THAT MAY AFFECT YOUR ACCOUNT

To protect you and other shareholders, the Fund reserves the right to:

        o  Refuse an exchange request if:

        1. you have exchanged twice from the same fund in any three-month
           period;

        2. the amount you wish to exchange equals the lesser of $1,000,000 or 1%
           of the Fund's net assets; or 3. you or your financial advisor have
           been advised that previous patterns of purchases and sales or
           exchanges have been considered excessive.

        o  Refuse any request to buy Fund shares;

        o  Reject any request received by telephone;

        o  Suspend or terminate telephone services;

        o  Reject a signature guarantee that SDC believes may be fraudulent;

        o  Close your fund account if its value falls below $500;

        o  Close your account if it does not have a certified taxpayer
           identification number.

TELEPHONE SERVICES

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 (which may
require a signature guarantee).

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.

DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS

The Fund generally pays any dividends from its net investment income and
distributes net capital gains realized on investments annually. It is expected
that the Fund's distributions will be primarily capital gains.

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

CAPITAL GAIN DISTRIBUTION:
A payment to mutual fund shareholders  which represents  profits realized on the
sale of securities in a fund's portfolio.

EX-DIVIDEND DATE:
The day on which any declared  distributions  (dividends  or capital  gains) are
deducted from a fund's assets before it calculates its NAV.
- --------------------------------------------------------------------------------

You may elect to:

(1) reinvest both dividends and capital gain distributions;

(2) receive dividends in cash and reinvest capital gain distributions; or

(3) receive both dividends and capital gain distributions in cash.

Your dividends and capital gain distributions will be reinvested if you do not
instruct otherwise or if you own Fund shares in a Seligman tax-deferred
retirement plan.

If you want to change your election, you may write SDC at the address listed on
the back cover of this prospectus or, if you have telephone services, you or
your financial advisor may call SDC. Your request must be received by SDC before
the record date to be effective for that dividend or capital gain distribution.

Cash dividends or capital gain distributions will be sent by check to your
address of record or, if you have current ACH bank information on file, directly
deposited into your predesignated bank account within 3-4 business days from the
payable date.

Dividends and capital gain distributions are reinvested to buy additional Fund
shares on the payable date using the NAV of the ex-dividend date.


Dividends on Class B, Class C, and Class D shares will be lower than the
dividends on Class A shares as a result of their higher 12b-1 fees. Capital gain
distributions will be 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.

Dividends paid by the Fund are taxable to you as ordinary income. 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.

                                  Fund History

The Fund was incorporated under the laws of the state of Maryland in 1982.

              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 either directly or through
American Depositary Receipts (ADRs), European Depositary Receipts (EDRs), or
Global Depositary Receipts (GDRs) (collectively, Depositary Receipts) in other
securities of foreign issuers. Foreign investments may be affected favorably or
unfavorably by changes in currency rates and exchange control regulations. There
may be less information available about a foreign company than about a 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 the
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.

Depositary Receipts are instruments generally issued by domestic banks or trust
companies that represent the deposits of a security of a foreign issuer. 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. EDRs are typically traded in Europe. GDRs are typically traded in
both Europe and the United States. Depositary Receipts may be issued under
sponsored or unsponsored programs. In sponsored programs, the issuer has made
arrangements to have its securities traded in the form of a Depositary Receipt.
In unsponsored programs, the issuers may not be directly involved in the
creation of the program. Although regulatory requirements with respect to
sponsored and unsponsored Depositary Receipt programs are generally similar, the
issuers of securities represented by unsponsored Depositary Receipts are not
obligated to disclose material information in the United States, and therefore,
the import of such information may not be reflected in the market value of such
receipts. The 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 Depositary Receipts which are traded in the United
States or to commercial paper and certificates of deposit issued by foreign
banks.

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

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


                                       2

<PAGE>

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. As a matter of
fundamental policy, 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 so
invested.

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 (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 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 from time to time borrow money to increase its portfolio
of securities. It may borrow only from banks and may not borrow in excess of
one-third of the market value of its assets, less liabilities other than such
borrowing. The Fund may pledge its assets only to the extent necessary to effect
permitted borrowing of up to 15% of its total assets on a secured basis. These
limits may be changed only by a vote of the shareholders. Current asset value
coverage of three times any amount borrowed is required at all times.

Borrowed money creates an opportunity for greater capital appreciation, but at
the same time increases exposure to capital risk. The net cost of any money
borrowed would be an expense that otherwise would not be incurred, and this
expense will limit the Fund's net investment income in any given period.

Any gain in the value of securities purchased with money borrowed in excess of
the cost of amounts borrowed would cause the net asset value of the Fund's
shares to increase more than otherwise would be the case. Conversely, any
decline in the value of securities purchased with money borrowed or any gain in
value less than the cost of amounts borrowed would cause net asset value to
decline more than would otherwise be the case.

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 dividends 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


                                       3
<PAGE>

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.

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.

Put options on securities may not be available to the Fund on reasonable terms
in many situations and the Fund may frequently choose not to purchase options
even when they are available. The Fund's ability to engage in option
transactions may be limited by tax considerations.

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:

- -    Borrow money, except in an amount not to exceed one-third of the value of
     its total assets less liabilities other than such borrowing; or mortgage or
     pledge any of its assets, except to the extent necessary to effect
     permitted borrowings of up to 15% of its total assets on a secured basis;

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



                                       4
<PAGE>

- -    Invest more than 5% of its total assets (taken at market) 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;

- -    Invest more than 25% of the value of its total assets in any one industry,
     except that the Fund will invest at least 25% of the value of its total
     assets in securities of companies principally engaged in the
     communications, information and related industries, except when investing
     for temporary defensive purposes;

- -    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;

- -    Purchase or sell commodities and commodity contracts or purchase or hold
     real estate;

- -    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;

- -    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

- -    Make loans, except loans of portfolio securities 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;

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

Under the Investment Company Act of 1940, as amended (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 100% of its assets in cash or cash
equivalents, including, but not limited to, prime commercial paper, bank
certificates of deposit, bankers' acceptances, or repurchase agreements for such
securities, and securities of the US Government and its agencies and
instrumentalities, as well as cash and cash equivalents denominated in foreign
currencies. The Fund's investments in foreign cash equivalents will be limited
to those that, in the opinion of the investment manager, equate generally to the
standards established for US cash equivalents. Investments in bank obligations
will be limited at the time of investment to the obligations of the 100 largest
domestic banks in terms of assets which are subject to regulatory supervision by
the US Government or state governments, and the obligations of the 100 largest
foreign banks in terms of assets with branches or agencies in the United States.

Portfolio Turnover

The Fund's portfolio turnover rate is calculated by dividing the lesser of
purchases or sales of portfolio securities for the year by the monthly average
of the value of the portfolio securities owned during the 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 years
ended December 31, 1998 and 1997 were 126.70% and 164.57%, respectively.

</TABLE>

(1)  For the Fund's year ended December 31, 1998. Effective January 16, 1998,
     the per meeting fee for Directors was increased by $1,000, which is
     allocated among all Funds in the Fund Complex.

(2)  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
December 31, 1998 was $32,629.

Messrs. Merow and Pitney no longer defer current compensation; however, they
have accrued deferred compensation (including earnings) in the amounts of
$51,431 and $33,582, respectively, as of December 31, 1998.

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

Sales Charges

Class A shares of the Fund may be issued without a sales charge to present and
retired directors, trustees, officers, employees (and their family members) of
the Fund, the other investment companies in the Seligman Group, and J. & W.
Seligman & Co. Incorporated and its affiliates. Family members are defined to
include lineal descendants and lineal ancestors, siblings (and their spouses and
children) and any company or organization controlled by any of the foregoing.
Such sales may also be made to employee benefit plans and thrift plans for such
persons and to any investment advisory, custodial, trust or other fiduciary
account managed or advised by J. & W. Seligman & Co. Incorporated or any
affiliate. The sales may be made for investment purposes only, and shares may be
resold only to the Fund.

Class A shares may be sold at net asset value to these persons since such sales
require less sales effort and lower sales related expenses as compared with
sales to the general public.

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 September 30, 1988 and by the shareholders at a special meeting
held on December 16, 1988. Amendments to the Management Agreement, effective
February 8, 1996, to increase the fee rate payable to Seligman by the Fund, were
approved by the Board of Directors on September 21, 1995 and by the shareholders
at a special meeting held on February 7, 1996. 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, 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 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.

Avenue, New York, New York 10017, acts as general distributor of the shares of

(1)  "Offering Price" is the amount that you actually pay for Fund shares; it
     includes the initial sales charge.

(2)  Your purchase of Class C shares must be for less than $1,000,000 because if
     you invest $1,000,000 or more, you will pay less in fees and charges if you
     buy Class A shares.

Seligman Services, Inc., (Seligman Services) an affiliate of Seligman, is a
limited purpose broker/dealer. Seligman Services is eligible to receive
commissions from certain sales of Fund shares. For years ended December 31,
1998, 1997 and 1996, Seligman Services received commissions in the amounts of
$404,711, $494,285 and $772,408, respectively.

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, Class C, 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 are allocated between the classes in accordance with a methodology approved
by the Fund's Board of Directors. Expenses of distribution activities that
benefit both the Fund and other Seligman funds will be allocated among the
applicable funds based on relative gross sales during the quarter in which such
expenses are incurred, 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 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
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 year ended
December 31, 1998 was $8,106,817, equivalent to 0.25% per annum of the average
daily net assets of Class A shares.

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 Class B shares (i) a 4%
sales commission to

                                       14

<PAGE>


Service Organizations 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 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 year to be paid from Class B 12b-1 fees
received from the Fund in any other 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
year ended December 31, 1998 was $7,384,792, equivalent to 1% per annum of the
average daily net assets of Class B shares.

Class C

Under the 12b-1 Plan, the Fund, with respect to Class C 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 C shares. The fee is used by Seligman Advisors as
follows: During the first year following the sale of Class C shares, a
distribution fee of .75% of the average daily net assets attributable to Class C
shares is used, along with any CDSC proceeds during the first eighteen months,
to (1) reimburse Seligman Advisors for its payment at the time of sale of Class
C shares of a 1.25% 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 C shares, a service fee of up to .25% of the average daily net assets
attributable to such Class C shares is used to reimburse Seligman Advisors for
its prepayment to Service Organizations at the time of sale of Class C shares of
a service fee of .25% of the net asset value of the Class C share sold (for
shareholder services to be provided to Class C shareholders over the course of
the one year immediately following the sale). The payment of service fees 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 C shares, the entire 12b-1 fee
attributable to such Class C shares is paid to Service Organizations for
providing continuing shareholder services and distribution assistance in respect
of the Fund. The Fund did not pay any 12b-1 fees in respect of Class C shares
for the fiscal year ended September 30, 1998 because no Class C shares were
issued or outstanding during such period.

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 such
Class D shares 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 .25% of the net asset value of the Class D shares sold (for shareholder
services to be provided to Class D shareholders over the course of the one year
immediately following the sale). The payment of service fees 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

                                       15

<PAGE>


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 the Fund. The total amount paid by the
Fund in respect of Class D shares for the year ended December 31, 1998 was
$10,339,390, 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 year to be paid from Class D 12b-1 fees in any other
year; however, in any year the Fund is not obligated to pay any 12b-1 fees in
excess of the fees described above.

As of December 31, 1998, Seligman Advisors has incurred $76,119 of unreimbursed
expenses in respect of the Fund's Class D shares. This amount is equal to .01%
of the net assets of Class D shares at December 31, 1998.

If the Fund's 12b-1 Plan is terminated in respect of Class D shares of the Fund,
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 year ended December 31,
1998, were spent on the following activities in the following amounts (no Class
C shares were outstanding during such fiscal year):




                                            Class A       Class B       Class D

*    Payment is made to FEP Capital,  L.P. to compensate it for having funded at
     the time of sale, payments to broker/dealers and underwriters.


The 12b-1 Plan was approved on July 16, 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 12b-1 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 November 23, 1992. The 12b-1 Plan
became effective in respect of the Class A shares on January 1, 1993. 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 was
approved in respect of the Class C shares on May 20, 1999 by the Directors,
including a majority of the Qualified Directors, and became effective in respect
of the Class C shares on June 1, 1999. 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


                                       16
<PAGE>



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 years
ended December 31, 1998, 1997 and 1996, Seligman Services received distribution
and service fees from the Fund pursuant to its 12b-1 Plan of $980,100, $961,731
and $714,490, 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.

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 years ended December 31, 1998, 1997 and 1996, the Fund paid total
brokerage commissions to others for execution, research and statistical services
in the amounts of $9,044,621, $7,436,884 and $4,496,690, respectively. The
amount of brokerage commissions paid by the Fund has increased materially from
1996 due to the Fund's increase in new assets under management.

Commissions

For the years ended December 31, 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.


                                       17
<PAGE>

Directed Brokerage

During the year ended December 31, 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 the year ended December 31, 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 1,000,000,000 shares of capital stock, each with
a par value of $0.10, divided into three classes, designated Class A common
stock, Class B common stock, Class C common stock, and Class D common stock.
Each share of the Fund's Class A, Class B, Class C, and Class D common 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 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 common 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 under
"Persons Entitled to Reductions") 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


                                       18
<PAGE>


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.

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. Section 403(b) plans
sponsored by public educational institutions are not eligible for net asset
value purchases based on the aggregate investment made by the plan or number of
eligible employees.

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 in the following instances:

(1)  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;


                                       19
<PAGE>


(2)  to separate accounts established and maintained by an insurance company
     which are exempt from registration under Section 3(c)(11) of the 1940 Act;

(3)  to registered representatives and employees (and their spouses and minor
     children) of any dealer that has a sales agreement with Seligman Advisors;

(4)  to financial institution trust departments;

(5)  to registered investment advisers exercising discretionary investment
     authority with respect to the purchase of Fund shares;

(6)  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;

(7)  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;

(8)  to other investment companies in the Seligman Group in connection with a
     deferred fee arrangement for outside directors;

(9)  to certain "eligible employee benefit plans" as discussed above;


(10) to those partners and employees of outside counsel to the Fund or its
     directors or trustees who regularly provide advice and services to the
     Fund, to other funds managed by Seligman, or to their directors or
     trustees; and

(11) in connection with sales pursuant to a 401(k) alliance program which has an
     agreement with Seligman Advisors.



CDSC Applicable to Class A Shares. Class A shares purchased without an initial
sales charge due to a purchase of $1,000,000 or more either alone or through 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 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.

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

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

Less than 1 year ..........................................   5%
1 year or more but less than 2 years ......................   4%
2 years or more but less than 3 years .....................   3%


                                       20
<PAGE>


3 years or more but less than 4 years .....................   3%
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%

Approximately eight years after purchase, Class B shares will convert
automatically into Class A shares. Shares purchased through reinvestment of
dividends and distribution on Class B shares also will convert automatically to
Class A shares along with the underlying shares on which they were earned.

Conversion occurs at the end of the month which precedes the eighth anniversary
of the purchase date. If Class B shares of the Fund are exchanged for Class B
shares of another Seligman mutual fund, the conversion period applicable to the
Class B shares acquired in the exchange will apply, and the holding period of
the shares exchanged will be tacked onto the holding period of the shares
acquired. Class B shareholders of the Fund exercising the exchange privilege
will continue to be subject to the Fund's CDSC schedule if such schedule is
higher or longer than the CDSC schedule relating to the new Class B shares. In
addition, Class B shares of the Fund acquired by exchange will be subject to the
Fund's CDSC schedule if such schedule is higher or longer than the CDSC schedule
relating to the Class B shares of the Seligman mutual fund from which the
exchange has been made.


Class C

Class C shares may be purchased at a price equal to the next determined net
asset value, plus an initial sales charge. Purchases of Class C shares by a
"single person" may be eligible for the reductions in initial sales charges
described above for Class A shares. Class C shares are subject to a CDSC of 1%
if the shares are redeemed within eighteen months of purchase, charged as a
percentage of the current net asset value or the original purchase price,
whichever is less.


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. Unlike Class B shares, Class D shares do not
automatically convert to Class A shares after eight years.


Systematic Withdrawals. Class B, Class C, and Class D shareholders who reinvest
both their dividends and capital gain distributions to purchase additional
shares of the Fund may use the Systematic Withdrawal Plan to withdraw up to 12%,
10% 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, Class C, 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;


                                       21
<PAGE>


(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.


If, with respect to a redemption of any Class A, Class B, Class C, 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.


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.

Fund Reorganizations


Class A shares and Class C 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.


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 and Class C
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, Class C, 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 are valued at the last sales 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. Securities traded on a foreign exchange or over-the-counter
market are valued at the last sales price on the primary exchange or


                                       22
<PAGE>


market on which they are traded. United Kingdom securities and securities for
which there are no recent sales transactions are valued based on quotations
provided by primary market makers in such securities. Any securities 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 60 days remaining to
maturity are generally valued at amortized cost. Short-term obligations with
more than 60 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.

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 and Class C shares are sold with a maximum initial
sales charge of 4.75% and 1.00%(1), respectively, and Class B and Class D shares
are sold at NAV(2). Using each Class's NAV at December 31, 1998, (except Class C
shares, which commences operations effective June 1, 1999), the maximum offering
price of the Fund's shares is as follows:

Class A
     Net asset value per share                                            $30.73

- --------------
(1)  In addition to the front-end sales charge of 1.00%, Class C shares are
     subject to a 1% CDSC if you redeem your shares within eighteen months of
     purchase.

(2)  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 also subject to a
     1% CDSC if you redeem your shares 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.


                                       23
<PAGE>


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
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 a 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
shareholders on the 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.


                                       24
<PAGE>


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 initial sales charges paid by shareholders of Class A shares of the Fund
for the years ended December 31, 1998, 1997 and 1996, amounted to $14,019,918,
$19,391,260 and $28,814,289, respectively, of which $1,537,225, $2,126,669 and
$3,145,037, respectively, was retained by Seligman Advisors. No Class C shares
of the Fund were issued or outstanding during such fiscal years.


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 year ended December 31, 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)
  ----------------      ----------------        -----------     ----------------

     $1,537,225              $475,038                $0            $576,783

(1)  Seligman Advisors has sold its rights to collect the distribution fees paid
     by the Fund in respect of Class B shares and 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 the year ended December 31, 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


                                       25
<PAGE>


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, 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. Seligman Advisors may from time
to time pay a bonus or other incentive to dealers that sell shares of the
Seligman mutual funds. 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-,
five-, and ten-year periods through December 31, 1998, were 27.56%, 27.77% and
25.48%, 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 capital gain 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 dividend and
capital gain distributions are reinvested in additional shares. It shows that a
$1,000 investment in Class A shares, assuming payment of the initial 4.75% sales
charge, made on December 31, 1988, had a value of $9,679 on December 31, 1998,
resulting in an aggregate total return of 867.91%.

The average annual total returns for the Fund's Class B shares for the one-year
period ended December 31, 1998 and for the period from April 22, 1996
(inception) through December 31, 1998, were 27.89% and 23.29%, respectively.
These returns were computed assuming that all dividends and capital gain
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 capital 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 $1,758 on
December 31, 1998, resulting in an aggregate total return of 75.76%.

The average annual total returns for the Fund's Class D shares for the one- and
five-year periods ended December 31, 1998 and for the period from May 3, 1993
(inception) through December 31, 1998, were 31.94%, 27.96% and 31.05%,
respectively. These returns were computed assuming that all of the dividends and
capital gain 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


                                       26
<PAGE>


return (income and capital) on Class D shares of the Fund, assuming all
dividends and capital 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 $4,628 on December
31, 1998, resulting in an aggregate total return of 362.84%.


Class C shares are a new class, effective June 1, 1999, so no performance data
is presented.


The results shown below should not be considered a representation of the
dividend income or gain or loss in capital value which may be realized from an
investment made in a class of shares of the Fund today.

today's investors seek their long-term financial goals.

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

Seligman Communications and Information Fund posted a 1998 total return of
33.92% based on the net asset value of Class A shares. The Fund outperformed the
28.58% total return of the Standard & Poor's 500 Composite Stock Price Index
(S&P 500), although it lagged the 52.55% total return of its peers, as measured
by the Lipper Science & Technology Funds Average. A discussion with your
Portfolio Manager regarding the Fund's results begins on page 2.

The past year was one of continued growth for the US economy, with real domestic
growth of 3.9%, marking the eighth year of economic expansion. In the equity
markets, exceptional performance from an extremely narrow list of stocks masked
a year of mediocre investment results in the broad markets. This narrowness, and
the divergence between larger- and smaller-company stocks, affected the
performance of technology stocks, in general, and Seligman Communications and
Information Fund, in particular. While the Fund posted impressive absolute
returns, it underperformed its peer group on a relative basis due to its
underweighted positions in large-cap technology and Internet stocks.

The "flight to quality" among US and international investors and the ongoing
ability of leading technology companies to beat earnings forecasts combined to
drive the valuations of large-cap technology stocks to new highs, at the expense
of many quality smaller technology companies. During this time, we underweighted
large caps to pursue growth opportunities at more reasonable prices. This
decision, while fundamentally sound, caused the Fund to underperform relative to
some of its peers, as large caps continued to lead the market higher through
year end.

In direct contrast to the earnings momentum that helped the largest tech stocks,
many investors disregarded earnings altogether when it came to Internet stocks.
Companies whose main business is the Internet generally have negative cash flows
and their potential for becoming profitable is uncertain. The Fund's lack of
exposure to this area is due to the fact that we look for companies with sound
fundamentals. While this commitment to our investment philosophy hurt the Fund's
relative performance during this time, we are convinced that maintaining a
portfolio of what we believe are quality companies -- including those whose
products and services are the backbone of the Internet, such as software, data
networking, and semiconductor manufacturers -- will serve our shareholders well
over the long term.

At this time, we believe that many of the largest technology stocks are fully
valued. Any broadening of the market in 1999 may negatively affect their share
prices. The Fund is well positioned for such a scenario, as we continue to look
for more reasonably priced mid-capitalization stocks. In terms of Internet
stocks, we don't believe that the current enthusiasm is sustainable. While the
Fund does not have much direct exposure to this group, we are nonetheless
concerned that if this market falls it may adversely affect investor psychology
regarding the broad technology sector. For 1999, we expect a challenging
environment for technology companies, confronted with economic uncertainties and
continued high volatility. However, for investors with a long-term time horizon,
we believe that technology remains one of the premier growth sectors of the
future.

Seligman continues to work to ensure that all of its operations are prepared for
the challenges posed by the Year 2000 (Y2K) computer problem. We are confident
that there will be no disruption in the investment and shareholder services
provided by your Fund as a result of Y2K. In addition, your portfolio management
team considers the potential ramifications of Y2K when making decisions on which
securities should be held by the Fund.

Thank you for your continued support of Seligman Communications and Information
Fund in 1998. We look forward to serving your investment needs in 1999.

INTERVIEW WITH YOUR PORTFOLIO MANAGER,
PAUL H. WICK

Q.   How did Seligman Communications and Information Fund perform in 1998?

A.   Seligman Communications and Information Fund's total return based on the
     net asset value of Class A shares was 33.92% for the year. While the Fund
     outperformed the 28.58% total return of the Standard & Poor's 500 Composite
     Stock Price Index (S&P 500), it lagged the 52.55% total return of its
     peers, as measured by the Lipper Science & Technology Funds Average.

Q.   Why did the Fund underperform its peer group?

A.   Within the technology sector, the strongest stock price gains came from the
     largest-capitalization companies and from Internet-related companies.
     Although Seligman Communications and Information Fund had many
     large-capitalization stocks that outperformed the market, it did not own
     them to the same magnitude as some competitor funds. In addition, your Fund
     generally avoided companies whose main business was the Internet, given
     their high valuations, often negative cash flow, and what we believe to be
     cloudy outlooks for achieving profitability.

     Large-capitalization technology stocks have benefited from a confluence of
     events. As segments of the technology industry have matured, larger
     companies have frequently gained market share and disproportionate
     profitability, as purchasing power, incumbency, and customer preference for
     fewer vendors rise in importance. These trends are noteworthy in the
     personal computer and data networking segments, where a few large companies
     have prospered and everyone else has not. In general, in many areas of
     technology, larger companies have had better profit growth than smaller
     firms.

     In addition, the unprecedented high returns of the S&P 500 since 1995 have
     increased investor preference for large-cap domestic equities at the
     expense of international and small- or mid-cap US stocks. The increasing
     popularity of S&P 500 index funds has added to this trend. Given that the
     S&P 500 is not equal-weighted, but market capitalization-weighted, the vast
     majority of money flowing into S&P 500 index funds ends up in the 100
     largest companies.

     Finally, the Fund was negatively affected by its holdings of media stocks.
     Although fundamentals were favorable throughout the year and the Fund's
     media holdings performed reasonably well, they did not match the
     performance of the largest-capitalization technology stocks.

INTERVIEW WITH YOUR PORTFOLIO MANAGER,
PAUL H. WICK


Q.   What are some of the underlying dynamics affecting the relative performance
     of small-, medium-, and large-capitalization technology stocks?

A.   Further aiding the superior relative performance of large-cap technology
     companies has been the disappointing performance of large consumer and
     industrial companies, whose profits were hurt by the Asian and South
     American currency crises. In response to the fundamental problems,
     large-company fund managers have shifted assets into big technology
     companies that continue to meet Wall Street expectations.

     The end result of all of these trends has been a snowballing of valuations,
     as already expensive stocks attain ever higher absolute and relative
     valuations. A case in point would be America Online, whose market value
     tripled between mid-October and year-end. In late December, America Online
     was added to the S&P 500 in recognition of its higher market value; of
     course, on the day of the announcement, shares of America Online rose 15%
     in anticipation of index fund buying. Today, America Online's market value
     exceeds that of Walt Disney, a company with significantly greater revenues,
     cash flow, profits, and proprietary content.

Q.   Given the high valuations, but generally superior profit growth of the
     bigger technology companies, what is the Fund's current strategy?

A.   We are sticking to our style. There are numerous mid-capitalization
     technology companies with excellent fundamentals that have gone
     unappreciated by the market. Your Fund has holdings in quite a few of these
     companies. In the large-capitalization area, we remain underweighted
     relative to the technology indices. We remain enthusiastic about the
     prospects for our investments in radio broadcasting and cable TV, as
     fundamentals are excellent and valuations reasonable.

Q.   Which of the Fund's sectors performed best in 1998?

A.   The top-performing area was computer hardware peripherals, which was
     positively affected by Year 2000 testing, increased demand for data
     storage, and market share consolidation in the computer industry.

Q.   Which of the Fund's sectors impaired results in 1998?

A.   The weakest areas of the Fund were the semiconductor-related sectors, which
     went through a serious recession in the wake of the Asian financial crisis.
     However, the semiconductor industry's fundamentals have recently begun to
     improve as a result of large reductions made on expenditures for new
     capacity over the past year.

Q.   Has the Fund changed its stance on Internet-related stocks?

A.   While the Fund continues to hold shares of numerous software, data
     networking, and semiconductor manufacturers whose products comprise the
     physical infrastructure of the Internet, your Manager remains wary of
     investing in public Internet stocks whose main business is the Internet.
     However, the Fund has made a number of small investments in private
     Internet companies, as valuations are much more reasonable than for public
     companies.

A TEAM APPROACH

Seligman Communications and Information Fund is managed by the Seligman
Technology Team, headed by Paul H. Wick. Mr. Wick and his team of seasoned
research professionals visit with the management of hundreds of technology
companies each year to identify those that offer the greatest potential for
growth. Stocks purchased for the Fund are continually monitored by the Team, and
disciplined buy/sell policies are followed.

INTERVIEW WITH YOUR PORTFOLIO MANAGER,
PAUL H. WICK


Q.   Which sectors appear to have the greatest appreciation potential in 1999?

A.   A number of sectors have excellent fundamentals and reasonable valuations:

     o    Semiconductor and semiconductor capital equipment companies have seen
          a significant improvement in business conditions, and appear to be in
          the early stages of a broad industry recovery.

     o    Integrated circuit design software companies are seeing improving
          orders fueled by the semiconductor industry recovery.

     o    Fundamentals for mechanical design software companies have begun to
          improve, while stock prices remain modestly valued.

     o    Entertainment software companies have never had better fundamentals,
          as the installed base of consumer PCs and video games continues to
          expand.

Q.   What is the likely impact of the Year 2000 (Y2K) computer problem on
     technology companies in 1999?

A.   While it is extraordinarily difficult to predict what will happen as a
     result of the passing of the millennium, we can make some educated guesses
     regarding government and corporate information technology spending this
     year. We believe that the majority of spending on computer software and
     hardware will take place in the first half of 1999, with correspondingly
     less money spent late in the year. As organizations grapple with final Y2K
     testing, they will be less inclined to add new software programs or
     computers to their data centers until some time in calendar year 2000.

     In recognition of these risks, we have begun to shift investments out of
     stocks heavily dependent on corporate technology spending and into
     companies more leveraged to consumer spending. Certainly, this is another
     reason to have a significant weighting in media stocks.

Q.   What is the outlook for technology?

A.   As we ended 1998, overall valuations for technology companies had never
     been higher. But where do they go from here? Can stock prices on the
     largest technology companies continue to go up? They can if these companies
     keep beating earnings estimates. What about companies whose main business
     is the Internet? As we said earlier, these companies typically have no
     earnings, but as long as individual investors shrug off fundamentals, stock
     prices for these companies may continue to rise. And, of course, Y2K is
     still a big question mark for 1999, with possible ramifications for the
     third and fourth quarters.

     But despite it all, technology continues to rise as a percentage of the
     world economy, and we see no sign of that slowing. Will the technology
     market remain volatile? Absolutely. But volatility creates opportunity, and
     a well-diversified, professionally managed mutual fund such as Seligman
     Communications and Information Fund can help investors who seek to take
     advantage of those opportunities.

FEDERAL TAX STATUS OF 1998
GAIN DISTRIBUTION FOR TAXABLE ACCOUNTS

- --------------------------------------------------------------------------------

A long-term capital gain distribution of $0.345 per share from 1997
undistributed net realized gain was paid on November 23, 1998, to Class A, B,
and D shareholders. In 1997, Congress revised the capital gains provisions, so
that depending on how long a security was owned when it was sold, investors may
have been faced with a 28% capital gains rate, a 20% rate, or both. In October
1998, Congress simplified the capital gains provisions so that, generally, all
gains on securities held more the one year are to be taxed at a maximum 20%
rate.

The long-term gain distribution is designated a "capital gain dividend" for
federal income tax purposes and is taxable to shareholders in 1998 as a
long-term gain from the sale of capital assets, no matter how long shares have
been owned, or whether the distribution was received in shares or in cash.
However, if shares on which a capital gain distribution was received are
subsequently sold, and such shares have been held for six months or less, any
loss on the sale would be treated as long-term to the extent that it offsets the
long-term gain distribution.

If the distribution was received in shares, the per share cost basis for federal
income tax purposes is $26.02 for Class A shares, $24.37 for Class B shares and
$24.35 for Class D shares.

A 1998 year-end statement of account activity and a 1998 tax package, which may
include a Form 1099-DIV, a Form 1099-B, and/or a Cost Basis Statement, have been
mailed to each shareholder. Form 1099-DIV shows the distributions paid to the
shareholder during the year. Form 1099-B shows the proceeds of any redemptions
paid to the shareholder during the year. Cost Basis Statements report all sales
or exchanges from a shareholder's account which may have resulted in a capital
gain or loss in 1998. The information shown on Forms 1099-DIV and 1099-B is
reported to the Internal Revenue Service as required by federal regulations.

PERFORMANCE OVERVIEW

     This chart compares a $10,000 hypothetical investment made in Seligman
Communications and Information 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 December 31,
1998, to a $10,000 investment made in the Lipper Science &Technology Funds
Average (Lipper Science &Technology Average) and the Standard &Poor's 500
Composite Stock Price Index (S&P 500) for the same period. The performances of
Seligman Communications and Information Fund Class B and Class D shares are not
shown in this chart but are included in the table on page 7. It is important to
keep in mind that the Lipper Science &Technology Average and the S&P 500 exclude
the effect of fees and/or sales charges.

     Investments in one economic sector, such as technology, may be subject to
greater price fluctuations than owning a portfolio of diversified investments.
In addition, the securities in which Seligman Communications and Information
Fund invests may be subject to greater government regulation, greater price
fluctuation, and limited liquidity. The stocks of smaller companies may be
subject to above-average risk. The Fund may invest in global technology stocks
which may be subject to additional risks, including currency fluctuations,
foreign taxation, differences in financial reporting practices, and rapid
changes in political and economic conditions.

     The performances of Class B and D shares will be greater than or less than
the performance shown for Class A shares, based on the differences in sales
charges and fees paid by shareholders.

     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 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 Plan after January 1, 1993, 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 Science & Technology Funds Average is an average of 73 science
     and technology funds and excludes the effect of the sales charges that may
     be incurred in connection with purchases or sales. The monthly performance
     is used in the Performance Overview. The S&P 500 is an unmanaged index that
     assumes investment of dividends and excludes the effect of fees and sales
     charges. Investors cannot invest directly in an average or an index.

   + The CDSC is 5% for periods of one year or less, and 3% since inception.

  ++ From April 30, 1996.

 +++ From April 30, 1993.

   # Represents net gain realized in November and December 1998, payable
     in 1999.

  ## Represents the per share amount of net unrealized appreciation of portfolio
     securities as of December 31, 1998.

NOTES TO FINANCIAL STATEMENTS


1. Multiple Classes of Shares -- Seligman Communications and Information 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%, 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 convertible securities and common
     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
     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
     December 31, 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. Any such reclassification
     will have no effect on net assets, results of operations, or net asset
     value per share of the Fund.

          For the year ended December 31, 1998, the Fund redeemed 212,696,394 of
     its shares from shareholders aggregating $5,191,055,429, of which
     approximately $149,500,000 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 December 31, 1998, amounted to $6,324,536,169 and $6,232,299,062,
respectively.

     At December 31, 1998, the cost of investments for federal income tax
purposes was $4,886,760,345, and the tax basis gross unrealized appreciation and
depreciation of portfolio securities amounted to $1,442,272,305 and
$161,065,431, respectively.

4. Short-Term Investments -- At December 31, 1998, the Fund owned short-term
investments which matured in less than seven days.

5. 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 0.90%
per annum of the first $3 billion of the Fund's average daily net assets, 0.85%
per annum of the next $3 billion of the Fund's average daily net assets, and
0.75% per annum of the Fund's average daily net assets in excess of $6 billion.
The management fee reflected in the Statement of Operations represents 0.88% per
annum of the Fund's average daily net assets.

NOTES TO FINANCIAL STATEMENTS


     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 $1,537,225 from sales of Class
A shares, after commissions of $12,482,693 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 the average daily net assets of the 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 December 31,
1998, fees incurred under the Plan aggregated $8,106,817, or 0.25% per annum of
the 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 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 December 31, 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 $7,384,792 and $10,339,390, 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
December 31, 1998, such charges amounted to $475,038.

     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 Bshares sold. The aggregate amount of such payments
retained by the Distributor, for the year ended December 31, 1998, amounted to
$576,783.

     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 December
31, 1998, Seligman Services, Inc. received commissions of $404,711 from the sale
of shares of the Fund. Seligman Services, Inc. also received distribution and
service fees of $980,100, pursuant to the Plan.

     Seligman Data Corp., which is owned by certain associated investment
companies, charged the Fund at cost $12,787,954 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.

     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 December 31, 1998, of $117,642
is included in other liabilities. Deferred fees and related accrued earnings are
not deductible for federal income tax purposes until such amounts are paid.

6. Committed Line of Credit -- Effective July 1, 1998, the Fund terminated its
$340 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%. 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 date of the agreement but is
renewable with the consent of the participating banks. Through December 31,
1998, the Fund has not borrowed from the credit facility.

7. Subsequent Event -- Litigation -- The Fund, certain of its current and former
directors, and the Manager have been named in a lawsuit filed in the United
States District Court for the Northern District of Maryland on February 5, 1999.
The complaint makes various allegations and claims relating to the February 1996
special meeting of the Fund's shareholders at which an increase in the
management fee rate payable to the Manager by the Fund was approved. The Fund
believes the claims to be without merit and intends to defend the action
vigorously.

FINANCIAL HIGHLIGHTS

   The tables below are intended to help you understand each Class's financial
performance for the past five years or from its inception if less than five
years. Certain information reflects financial results for a single share of a
Class that was held throughout the periods shown. Per share amounts are
calculated using average shares outstanding. "Total return" shows the rate that
you would have earned (or lost) on an investment in each Class, assuming you
reinvested all your capital gain distributions. Total returns do not reflect any
sales charges, and are not annualized for periods of less than one year.

REPORT OF INDEPENDENT AUDITORS



- --------------------------------------------------------------------------------

The Board of Directors and Shareholders,
Seligman Communications and Information Fund, Inc.:

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of Seligman Communications and Information Fund,
Inc. as of December 31, 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
December 31, 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
Communications and Information Fund, Inc. as of December 31, 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.

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, how shares are bought and sold, fund fees and other
charges, and the fund's financial highlights.

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.

PART C.    OTHER INFORMATION (CONTINUED)

           Insofar as indemnification for liabilities arising under the

           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 and 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.

               SELIGMAN COMMUNICATIONS AND INFORMATION FUND, INC.

                             ARTICLES SUPPLEMENTARY

                  Seligman Communications and Information Fund, Inc., a Maryland
corporation having its principal office in Baltimore City, Maryland (hereinafter
called the "Corporation") and registered as an open-end investment company under
the Investment Company Act of 1940, as amended (the "Investment Company Act"),
hereby certifies to the State Department of Assessments and Taxation of Maryland
that:

                  FIRST: The total number of shares of capital stock of all
classes which the Corporation has authority to issue is 1,000,000,000 shares,
which were previously classified by the Board of Directors of the Corporation
into three classes designated as Class A Common Stock, Class B Common Stock and
Class D Common Stock. The number of authorized shares of Class A Common Stock,
Class B Common Stock and Class D Common Stock each consisted of the sum of x and
y, where x equaled the issued and outstanding shares of such class and y equaled
one-third of the authorized but unissued shares of Common Stock of all classes;
PROVIDED that at all times the aggregate authorized, issued and outstanding
shares of Class A, Class B and Class D Common Stock shall not exceed the
authorized number of shares of Common Stock; and, in the event application of
the formula above would have resulted, at any time, in fractional shares, the
applicable number of authorized shares of each class was to have been rounded
down to the nearest whole number of shares of such class.

                  SECOND: Pursuant to the authority of the Board of Directors to
classify and reclassify unissued shares of capital stock, the Board of Directors
has reclassified the unissued shares of Class A Common Stock, Class B Common
Stock and Class D Common Stock into the following classes and has provided for
the issuance of shares of such classes. The terms of the Common Stock as set by
the Board of Directors are as follows:

                  (a) The total number of shares of all classes of stock which
         the Corporation has authority to issue is 1,000,000,000 shares of
         common stock ("Shares") of the par value of $.10 each having an
         aggregate par value of $100,000,000. The Common Stock of the
         Corporation shall have four classes of shares, which shall be
         designated Class A Common Stock, Class B Common Stock, Class C Common
         Stock and Class D Common Stock. The number of authorized shares of
         Class A Common Stock, of Class B Common Stock, of Class C Common Stock
         and of Class D Common Stock shall each consist of the sum of x and y,
         where x equals the issued and outstanding shares of such class and y
         equals one-fourth of the authorized but unissued shares of Common Stock
         of all classes; PROVIDED that at all times the aggregate authorized,
         issued and outstanding shares of Class A, Class B, Class C and Class D
         Common Stock shall not exceed the authorized number of shares of Common
         Stock (I.E., 1,000,000,000 shares of Common Stock until changed by
         further action of the Board of Directors in accordance with Section
         2-208.1 of the Maryland General Corporation Law, or any successor
         provision); and, in the event application of the formula above would
         result, at any time, in fractional shares, the applicable number of
         authorized shares of each class shall be rounded down to the nearest
         whole number of


                                      -1-


<PAGE>


         shares of such class. Any class of Common Stock shall be referred to
         herein individually as a "Class" and collectively, together with any
         further class or classes from time to time established, as the
         "Classes".

                  (b) All Classes shall represent the same interest in the
         Corporation and have identical voting, dividend, liquidation, and other
         rights; PROVIDED, HOWEVER, that notwithstanding anything in the charter
         of the Corporation to the contrary:

                           (1) Class A shares may be subject to such front-end
                  sales loads as may be established by the Board of Directors
                  from time to time in accordance with the Investment Company
                  Act and applicable rules and regulations of the National
                  Association of Securities Dealers, Inc. (the "NASD").

                           (2) Class B shares may be subject to such contingent
                  deferred sales charges as may be established from time to time
                  by the Board of Directors in accordance with the Investment
                  Company Act and applicable rules and regulations of the NASD.
                  Subject to subsection (6) below, each Class B share shall
                  convert automatically into Class A shares on the last business
                  day of the month that precedes the eighth anniversary of the
                  date of issuance of such Class B share; such conversion shall
                  be effected on the basis of the relative net asset values of
                  Class B shares and Class A shares as determined by the
                  Corporation on the date of conversion.

                           (3) Class C shares may be subject to such front-end
                  sales loads and such contingent deferred sales charges as may
                  be established from time to time by the Board of Directors in
                  accordance with the Investment Company Act and applicable
                  rules and regulations of the NASD.

                           (4) Class D shares may be subject to such contingent
                  deferred sales charges as may be established from time to time
                  by the Board of Directors in accordance with the Investment
                  Company Act and applicable rules and regulations of the NASD.

                           (5) Expenses related solely to a particular Class
                  (including, without limitation, distribution expenses under a
                  Rule 12b-1 plan and administrative expenses under an
                  administration or service agreement, plan or other
                  arrangement, however designated, which may differ between the
                  Classes) shall be borne by that Class and shall be
                  appropriately reflected (in the manner determined by the Board
                  of Directors) in the net asset value, dividends, distribution
                  and liquidation rights of the shares of that Class.

                           (6) At such time as shall be permitted under the
                  Investment Company Act, any applicable rules and regulations
                  thereunder and the provisions of any exemptive order
                  applicable to the Corporation, and as may be determined by the
                  Board of Directors and disclosed in the then current
                  prospectus of the Corporation, shares of a


                                      -2-


<PAGE>


                  particular Class may be automatically converted into shares of
                  another Class; PROVIDED, HOWEVER, that such conversion shall
                  be subject to the continuing availability of an opinion of
                  counsel to the effect that such conversion does not constitute
                  a taxable event under Federal income tax law. The Board of
                  Directors, in its sole discretion, may suspend any conversion
                  rights if such opinion is no longer available.

                           (7) As to any matter with respect to which a separate
                  vote of any Class is required by the Investment Company Act or
                  by the Maryland General Corporation Law (including, without
                  limitation, approval of any plan, agreement or other
                  arrangement referred to in subsection (5) above), such
                  requirement as to a separate vote by the Class shall apply in
                  lieu of single Class voting, and, if permitted by the
                  Investment Company Act or any rules, regulations or orders

Seligman Communications and Information Fund, Inc.,
   100 Park Avenue,
   New York, N.Y.  10017.


Dear Sirs:

     In  connection  with  Post-Effective  Amendment  No.22 to the  Registration
Statement  on Form N-1A  (File  No.  2-80168)  of  Seligman  Communications  and
Information Fund, Inc., a Maryland corporation (the "Fund"), which you expect to
file under the Securities Act of 1933, as amended (the "Securities  Act"),  with
respect to an indefinite number of shares of capital stock, par value $0.100 per
share,  of the class  designated as Class C shares (the  "Shares"),  we, as your
counsel, have examined such corporate records, certificates and other documents,
and such questions of law, as we have  considered  necessary or appropriate  for
the purposes of this opinion.

     The  number of  shares  of each  class of  capital  stock  that the Fund is
authorized  to issue at any time is determined by adding to the number of shares
of such  class  then  outstanding  additional  authorized  shares  in an  amount
determined  according to a formula set forth in the Fund's charter.  The formula
allocates  to each class an equal  portion of the number of shares  representing
the difference between the number of shares that the Fund is authorized to issue
and the total number of shares of all classes outstanding at such time. Upon the
basis of such  examination,  we advise  you that,  in our  opinion,  the Fund is
authorized  to issue the  number of Shares  determined  in  accordance  with the
charter of the Fund as described  above and, when the  Post-Effective  Amendment
referred to above has become  effective  under the Securities Act and the Shares
have been issued  (a) for at least the par value thereof in accordance  with the
Registration  Statement  referred  to above,  (b) so  as not to exceed  the then
authorized  number of Shares and (c) in accordance with the authorization of the
Board of Directors,  the Shares will be duly and validly issued,  fully paid and
non-assessable.


<PAGE>



     The  foregoing  opinion is limited to the Federal laws of the United States
and the General Corporation Law of the State of Maryland,  and we are expressing
no opinion as to the effect of the laws of any other jurisdiction.

     We hereby  consent  to the  filing of this  opinion  as an  exhibit  to the
Post-Effective  Amendment  referred to above. In giving such consent,  we do not
thereby  admit that we are in the category of persons  whose consent is required
under Section 7 of the Securities Act.


                                                     Very truly yours,

                                                     SULLIVAN & CROMWELL

                        CONSENT OF INDEPENDENT AUDITORS

Seligman Communications and Information Fund, Inc.:

We  consent  to the  use in  Post-Effective  Amendment  No.  22 to  Registration
Statement  No.  2-80168 of our report dated  February 5, 1999,  appearing in the
Annual Report to  Shareholders  for the year ended  December 31, 1998,  which is

1.       The Fund hereby sells to Purchaser and Purchaser purchases 1 Class C
         share (the "Share") of Capital Stock (par value $.10) of the Fund at a

                                  Title:  Vice President

           ADMINISTRATION, SHAREHOLDER SERVICES AND DISTRIBUTION PLAN
           ----------------------------------------------------------

                  As amended and restated through June 1, 1999

                  SECTION 1. Seligman Communications & Information Fund, Inc.
(the "Fund") will pay fees to Seligman Advisors, Inc., the principal underwriter
of its shares (the "Distributor"), for administration, shareholder services and
distribution assistance for the Class A, Class B, Class C and Class D shares of
the Fund. As a result, the Fund is adopting this Administration, Shareholder
Services and Distribution Plan (the "Plan") pursuant to Section 12(b) of the
Investment Company Act of 1940, as amended (the "Act") and Rule 12b-1
thereunder.

                  SECTION 2. Pursuant to this Plan, the Fund may pay to the
Distributor a shareholder servicing fee of up to .25% on an annual basis of the
average daily net assets of the Fund (payable quarterly with respect to Class A
and monthly with respect to Class B, Class C and Class D) and a distribution fee
of .75% on an annual basis, payable monthly, of the average daily net assets of
the Fund attributable to the Class B Shares and a distribution fee of up to .75%
on an annual basis, payable monthly, of the average daily net assets of the Fund
attributable to Class C and Class D shares. Such fees will be used in their
entirety by the Distributor to make payments for administration, shareholder
services and distribution assistance, including, but not limited to (i)
compensation to securities dealers and other organizations (each, a "Service
Organization" and collectively, the "Service Organizations"), for providing
distribution assistance with respect to assets invested in the Fund, (ii)
compensation to Service Organizations for providing administration, accounting
and other shareholder services with respect to Fund shareholders, and (iii)
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 the Distributor's costs incurred in connection with its
marketing efforts with respect to shares of the Fund. To the extent a Service
Organization provides administration, accounting and other shareholder services,
payment for which is not required to be made pursuant to a plan meeting the
requirements of Rule 12b-1, a portion of the fee paid by the Fund shall be
deemed to include compensation for such services. The fees received from the
Fund hereunder in respect of the Class A shares may not be used to pay any
interest expense, carrying charges or other financing costs, and fees received
hereunder may not be used to pay any allocation of overhead of the Distributor.
The fees of any particular class of the Fund may not be used to subsidize the
sale of shares of any other class. The fees payable to Service Organizations
from time to time shall, within such limits, be determined by the Directors of
the Fund.

                  SECTION 3. J. & W. Seligman & Co. Incorporated, the Fund's
investment manager (the "Manager"), in its sole discretion, may make payments to
the Distributor for similar purposes. These payments will be made by the Manager
from its own resources, which may include the management fee that the Manager
receives from the Fund.

                  SECTION 4. This Plan shall continue in effect through December
31 of each year so long as such continuance is specifically approved at least
annually by vote of a majority of both (a) the Directors of the Fund and (b) the
Qualified Directors, cast in person at a meeting called for the purpose of
voting on such approval.



                                       1
<PAGE>


                  SECTION 5. The Distributor shall provide to the Fund's
Directors, and the Directors shall review, at least quarterly, a written report
of the amounts so expended and the purposes for which such expenditures were
made.

                  SECTION 6. This Plan may be terminated by the Fund with
respect to any class at any time by vote of a majority of the Qualified
Directors, or by vote of a majority of the outstanding voting securities of such
class. If this Plan is terminated in respect of a class, no amounts (other than
amounts accrued but not yet paid) would be owed by the Fund to the Distributor
with respect to such class.

                  SECTION 7. All agreements related to this Plan shall be in
writing, and shall be approved by vote of a majority of both (a) the Directors
of the Fund and (b) the Qualified Directors, cast in person at a meeting called
for the purpose of voting on such approval, provided, however, that the identity
of a particular Service Organization executing any such agreement may be
ratified by such a vote within 90 days of such execution. Any agreement related
to this Plan shall provide:

         A.       That such agreement may be terminated in respect of any class
                  of the Fund at any time, without payment of any penalty, by
                  vote of a majority of the Qualified Directors or by vote of a
                  majority of the outstanding voting securities of the class, on
                  not more than 60 days' written notice to any other party to
                  the agreement; and

         B.       That such agreement shall terminate automatically in the
                  event of its assignment.

                  SECTION 8. This Plan may not be amended to increase materially
the amount of fees permitted pursuant to Section 2 hereof without the approval
of a majority of the outstanding voting securities of the relevant class and no
material amendment to this Plan shall be approved other than by vote of a
majority of both (a) the Directors of the Fund and (b) the Qualified Directors,
cast in person at a meeting called for the purpose of voting on such approval.
This Plan shall not be amended to reduce the distribution fee payable to the
Distributor pursuant to Section 2 hereof in respect of Class B shares, unless
the shareholder servicing fee payable pursuant to Section 2 hereof for
compensation to Service Organizations for providing administration, accounting
and other shareholder services has been eliminated, provided, however that the
distribution fee in respect of Class B shares may be reduced without change to
the shareholder servicing fee, if and to the extent required in order to comply
with any applicable laws or regulations, including applicable rules of the
National Association of Securities Dealers, Inc. regulating maximum sales
charges.

                  SECTION 9. The Fund is not obligated to pay any
administration, shareholder services or distribution expense in excess of the
fee described in Section 2 hereof, and, in the case of Class A shares, any
expenses of administration, shareholder services and distribution of Class A
shares of the Fund accrued in one fiscal year of the Fund may not be paid from
administration, shareholder services and distribution fees received from the
Fund in respect of Class A shares in any other fiscal year.

                  SECTION 10. As used in this Plan, (a) the terms "assignment",
"interested person" and "vote of a majority of the outstanding voting
securities" shall have the respective meanings specified in the Act and the
rules and regulations thereunder, subject to such exemptions as may be granted
by the Securities and Exchange Commission and (b) the term "Qualified Directors"
shall mean the Directors of the Fund who are not "interested persons" of the
Fund and have no direct or indirect financial interest in the operation of this
Plan or in any agreement related to this Plan.
