  The purpose of this table is to assist investors in understanding the vari-
ous costs and expenses which shareholders of the Fund bear directly or indi-
rectly. The sales load on Class A shares is a one-time charge paid at the time
of purchase of shares. Reductions in sales loads are available in certain cir-
cumstances. The contingent deferred sales load on Class D shares is a one-time
charge paid only if shares are redeemed within one year of purchase. For more
information concerning reduction in sales loads and for a more complete de-
scription of the various costs and expenses, see "Purchase Of Shares," "Re-
demption Of Shares" and "Management Services" herein. The Fund's Administra-
tion, Shareholder Services and Distribution Plan to which the caption "12b-1
Fees" relates, is discussed under "Administration, Shareholder Services and
Distribution Plan" herein.

You would pay the following expenses on a

turn and (2) redemption at the end  of each
time period............................Class A   $63     $97    $133     $234

THE EXAMPLE SHOULD NOT BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE EX-
PENSES. ACTUAL EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN AND THE 5% AN-
NUAL RETURN USED IN THIS EXAMPLE IS A HYPOTHETICAL RATE.
          
* Includes an annual distribution fee of .75 of 1% and an annual service fee
  of .25 of 1%. Pursuant to the Rules of the National Association of Securi-
  ties Dealers, Inc., the aggregate deferred sales loads and annual distribu-
  tion fees on Class D shares of the Fund may not exceed 6.25% of total gross
  sales, subject to certain exclusions. The 6.25% limitation is imposed on the
  Fund rather than on a per shareholder basis. Therefore, a long-term Class D
  shareholder of the Fund may pay more in total sales loads (including distri-
  bution fees) than the economic equivalent of 6.25% of such shareholder's in-
  vestment in the shares.     
   
+ Assuming (1) 5% annual return and (2) no redemption at the end of one year,
  the expenses on a $1,000 investment would be $25.

                             FINANCIAL HIGHLIGHTS
   
  The Fund's financial highlights for the periods presented below have been
audited by Deloitte & Touche LLP, independent auditors. This information,
which is derived from the financial and accounting records of the Fund, should
be read in conjunction with the 1994 financial statements and notes contained
in the 1994 Annual Report, which may be obtained by calling or writing the
Fund at the telephone numbers or address provided on the cover page of this
Prospectus.     
 
  The per share operating performance data is designed to allow investors to
trace the operating performance, on a per share basis, from the Fund's begin-
ning net asset value to its ending net asset value so that investors may un-
derstand what effect the individual items have on their investment, assuming
it was held throughout the period. Generally, the per share amounts are de-
rived by converting the actual dollar amounts incurred for each item, as dis-
closed in the financial statements, to their equivalent per share amount.
 
  The total return based on net asset value measures the Fund's performance
assuming investors purchased Fund shares at net asset value as of the begin-
ning of the period, invested dividends and capital gains paid at net asset
value and then sold their shares at the net asset value per share on the last
day of the period. The total return computations do not reflect any sales
loads investors may incur in purchasing or selling shares of the Fund. Total
returns for periods of less than one year are not annualized.

ALTERNATIVE DISTRIBUTION SYSTEM
   
  The Fund offers two classes of shares. Class A shares are sold to investors
who have concluded that they would prefer to pay an initial sales load and have
the benefit of lower continuing charges. Class D shares are sold to investors
choosing to pay no initial sales load, a higher distribution fee and with, re-
spect to redemptions within one year of purchase, a CDSL. The Alternative Dis-
tribution System allows investors to choose the method of purchasing shares
that is most beneficial in light of the amount of the purchase, the length of
time the shares are expected to be held and other relevant circumstances. In-
vestors should determine whether under their particular circumstances it is
more advantageous to incur an initial sales load and be subject to lower ongo-
ing charges, as discussed below, or to have the entire initial purchase price
invested in the Fund with the investment thereafter being subject to higher on-
going charges and, for a one-year period, a CDSL.     
 
  Investors who qualify for reduced sales loads, as described under "Purchase
Of Shares" below might choose to purchase Class A shares because Class A shares
would be subject to lower ongoing fees. The amount invested in the Fund, howev-
er, is reduced by the initial sales loads deducted at the time of purchase.
   
  Investors who do not qualify for reduced initial sales loads but expect to
maintain their investment for an extended period of time might also choose to
purchase Class A shares because over time the accumulated continuing distribu-
tion fee of Class D shares may exceed the initial sales load and lower distri-
bution fee of Class A shares. This consideration must be weighed against the
fact that the amount invested in the Fund will be reduced by the initial sales
load deducted at the time of purchase. Furthermore, the distribution fees will
be offset to the extent any return is realized on the additional funds ini-
tially invested under the Class D alternative.     
   
  Alternatively, some investors might choose to have all of their funds in-
vested initially in Class D shares although remaining subject to a higher con-
tinuing distribution fee and, for a one-year period, a CDSL as described below.
For example, an investor who does not qualify for reduced sales loads would
have to hold Class A shares for more than 6.33 years for the Class D distribu-
tion fee to exceed the initial sales load plus the distribution fee on Class A
shares. This example does not take into account the time value of money, which
further reduces the impact of the Class D shares' 1% distribution fee, other
expenses charged to each class, fluctuations in net asset value or the effect
of the return on the investment over this period of time.     
   
  The two classes of shares represent interests in the same portfolio of in-
vestments, have the same rights and are generally identical in all respects ex-
cept that each class bears its separate distribution and certain class expenses
and has exclusive voting rights with respect to any matter to which a separate
vote of any class is required by the Investment Company Act of 1940, as amended
(the "1940 Act") or Maryland law. The net income attributable to each class and
dividends payable on the shares of each class will be reduced by the amount of
distribution and other expenses of each class. Class D shares bear higher dis-
tribution fees, which will cause the Class D shares to pay lower dividends than
the Class A shares. The two classes also have separate exchange privileges.
    
  The Directors of the Fund believe that no conflict of interest currently ex-
ists between the Class A and Class D shares. On an ongoing basis, the Direc-
tors, in the exercise of their fiduciary duties under the 1940 Act, and Mary-
land law, will seek to ensure that no such conflict arises. For this purpose,
the Directors will monitor the Fund for the existence of any material conflict
among the classes and will take such action as is reasonably necessary to elim-
inate any such conflicts that may develop.
 
  DIFFERENCES BETWEEN CLASSES. The primary distinctions between Class A and
Class D shares are
 
                                       4

their sales load structures and ongoing expenses as set forth below. Each class
has advantages and disadvantages for different investors, and investors should
choose the class that best suits their circumstances and their objectives.

INVESTMENT OBJECTIVE, POLICIES AND RISKS
 
  The Fund is an open-end diversified management investment company, as defined
in the 1940 Act, or mutual fund, incorporated in Maryland in 1982.
 
  The Fund invests to produce capital gain. Income is not an objective.
 
  Investing for capital gain ordinarily exposes capital to added risk. Shares
of the Fund are intended for you only if you are able and willing to take such
risk. There can be no assurance that the Fund's investment objectives will be
attained.
 
  The Fund seeks to achieve its objective by investing in a portfolio consist-
ing of securities of companies operating in virtually all aspects of the commu-
nications, information and related industries. It invests at least 80% of its
net assets, exclusive of government securities, short-term notes, cash and cash
equivalents, in securities of companies engaged in these industries.
   
  The communication and use of information using existing and developing tech-
nologies is increasingly permeating global civilization. Consequently, there
are opportunities for continued growth in demand for components, products, me-
dia and systems to collect, store, retrieve, transmit, process, distribute,
record, reproduce and put information to use. The pervasive impact of communi-
cations and information upon society is being accelerated by the blending of
computers with telecommunications systems, with resulting lower costs and
higher efficiencies. Accordingly, companies engaged in the production of meth-
ods for using electronic technology to communicate information are important in
the Fund's portfolio. However, older technologies such as photography and print
may also be represented. Companies that successfully converge technologies--
medical databases and computer networks for example--are sought for the portfo-
lio.     
 
  The value of Fund shares may be susceptible to factors affecting the communi-
cations, information and related industries. These industries may be subject to
greater governmental regulation than many other industries and changes in gov-
ernmental policies and the need for regulatory approvals may have a material
effect on the products and services of these industries.
 
  Although 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 are held in the Fund's portfolio, rapidly changing technologies and
the expansion of the communications, information and related industries provide
a favorable environment for investing in companies of small to medium size. Se-
curities of smaller, less seasoned companies may be subject to greater price
fluctuation, limited liquidity and above-average investment risk.
   
  The Fund invests primarily in common stocks. It also may 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.     
 
                                       5
<PAGE>
 
  It is the Fund's present intention to invest not more than 5% of its net as-
sets in debt securities which are not rated within the four highest rating cat-
egories by Standard & Poor's Corporation or by Moody's Investors Service, Inc.
 
  Securities owned are kept under continuing supervision, and changes may be
made whenever such securities no longer seem to meet the Fund's capital gain
objectives. Neither the length of time a security has been held nor the rate of
turnover of the Fund's portfolio is considered a limiting factor on changes.
Portfolio turnover may vary with such changes.
 
  BORROWING. The Fund may from time to time borrow money to increase its port-
folio 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, or pledge more than 10% of its total assets, taken at cost, to
secure the borrowing. These limits may be changed only by a vote of the share-
holders. Current asset value coverage of three times any amount borrowed is re-
quired 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 ex-
pense could limit the Fund's net investment income in any given period.
 
  LENDING OF PORTFOLIO SECURITIES. The Fund may lend portfolio securities to
brokers or dealers, banks or other institutional borrowers of securities. 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 port-
folio securities are on loan, the borrower pays the Fund an amount equivalent
to any dividends or interest paid on the securities and the Fund may invest the
cash collateral and earn additional income or may receive an agreed upon amount
of interest income from the borrower.
 
  RESTRICTED SECURITIES. The Fund may invest up to 15% of its net assets in il-
liquid securities, including restricted securities (i.e., securities not read-
ily marketable without registration under the Securities Act of 1933 (the "1933
Act")) and other securities that are not readily marketable. The Fund may pur-
chase restricted securities that can be offered and sold to "qualified institu-
tional buyers" under Rule 144A of the 1933 Act, and the Fund's Board of Direc-
tors 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 secu-
rity (focusing on such factors, among others, as trading activity and avail-
ability 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 restricted securities offered and sold under Rule 144A will develop. This
investment practice could have the effect of increasing the level of illiquid-
ity in the Fund to the extent that qualified institutional buyers become for a
time uninterested in purchasing Rule 144A securities.
   
  FOREIGN SECURITIES. The Fund may invest in commercial paper and certificates
of deposit issued by foreign banks and may invest in other securities of for-
eign issuers directly or through American Depository Receipts ("ADRs"), Euro-
pean Depository Receipts ("EDRs") or Global Depository Receipts ("GDRs") (col-
lectively, "Depository Receipts"). Foreign investments may be affected favor-
ably or unfavorably by changes in currency rates and exchange control regula-
tions. There may be less information available about a foreign company than
about a U.S. company and foreign companies may not be subject to reporting
standards and requirements comparable to those applicable to U.S. companies.
Foreign securities may not be as liquid as U.S. securities. Securities of for-
eign companies may involve greater market risk than securities of U.S. compa-
nies, and foreign brokerage commissions and custody fees are generally higher
than in the United States. Investments in foreign securities may also be sub-
ject to local economic or political risks, political instability and possible
nationalization of issuers. Depository Receipts are instruments generally is-
sued by domestic banks or trust compa     
 
                                       6
<PAGE>
 
   
nies that represent the deposits of a security of a foreign issuer. ADRs may be
publicly traded on exchanges or over-the-counter in the United States and are
quoted and settled in dollars at a price that generally reflects the dollar
equivalent of the home country share price. EDRs and GDRs are typically traded
in Europe and in both Europe and the United States, respectively. Depository
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 Depository Receipt. In unsponsored programs, the issuers may not be
directly involved in the creation of the program. Although regulatory require-
ments with respect to sponsored and unsponsored Depository Receipt programs are
generally similar, the issuers of securities represented by unsponsored Deposi-
tory 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 Depository Receipts which are
traded in the United States or to commercial paper and certificates of deposit
issued by foreign banks.     
 
  Except as noted above, the foregoing investment policies are not fundamental
and the Board of Directors of the Fund may change such policies without the
vote of a majority of its outstanding voting securities. As a matter of policy,
the Board would not change the Fund's investment objective of seeking to pro-
duce capital gain without such a vote. A more detailed description of the
Fund's investment policies, including a list of those restrictions on the
Fund's investment activities which cannot be changed without such a vote, ap-
pears in the Statement of Additional Information. Under the 1940 Act, a "vote
of a majority of the outstanding voting securities" of the Fund means the af-
firmative vote of the lesser of (1) 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 per-
son or by proxy.
 
MANAGEMENT SERVICES
 
  THE MANAGER. The Board of Directors provides broad supervision over the af-
fairs of the Fund. Pursuant to a Management Agreement approved by the Board and
the shareholders of the Fund, the Manager manages the investments of the Fund
and administers the business and other affairs of the Fund. The address of the
Manager is 100 Park Avenue, New York, NY 10017.
   
  The Manager also serves as manager of sixteen other investment companies
which, together with the Fund, comprise the "Seligman Group." These companies
are: Seligman Capital Fund, Inc., Seligman Cash Management Fund, Inc., Seligman
Common Stock Fund, Inc., Seligman Frontier Fund, Inc., Seligman Growth Fund,
Inc., Seligman Henderson Global Fund Series, Inc., Seligman High Income Fund
Series, Seligman Income Fund, Inc., Seligman New Jersey Tax-Exempt Fund, Inc.,
Seligman Pennsylvania Tax- Exempt Fund Series, Seligman Portfolios, Inc., Se-
ligman Quality Municipal Fund, Inc., Seligman Select Municipal Fund, Inc., Se-
ligman Tax-Exempt Fund Series, Inc., Seligman Tax-Exempt Series Trust and Tri-
Continental Corporation. The aggregate assets of the Seligman Group are approx-
imately $7.3 billion. The Manager also provides investment management or advice
to institutional accounts having an aggregate value of approximately $3.3 bil-
lion.     
 
  Mr. William C. Morris is Chairman and President of the Manager and Chairman
of the Board and Chief Executive Officer of the Fund. Mr. Morris owns a
majority of the outstanding voting securities of the Manager.
   
  The Manager provides senior management for Seligman Data Corp., a wholly-
owned subsidiary of certain other investment companies in the Seligman Group,
which performs, at cost, certain recordkeeping functions for the Fund, main-
tains the records of shareholder accounts and furnishes dividend paying, re-
demption and related services.     
          
  The Manager is entitled to receive a management fee, calculated daily and
payable monthly, equal to 0.75% of the daily net assets of the Fund.     
 
                                       7
<PAGE>
 
   
  The Fund pays all its expenses other than those assumed by the Manager. Total
expenses of the Fund's Class A and Class D shares, respectively, for the year
ended December 31, 1994 amounted to 1.65% and 2.50%, respectively, of the aver-
age daily net assets of each class.     
   
  THE SUBADVISER. On May 19, 1994, shareholders of the Fund approved a
Subadvisory Agreement between the Manager and Seligman Henderson Co. (the
"Subadviser") that provides that the Subadviser shall act as Subadviser to the
Fund with respect to a portion of the Fund's assets as designated by the Manag-
er, which shall include all or a portion of the Fund's foreign investments
("Qualifying Assets"). The Fund has a non-fundamental policy under which it may
invest up to 10% of its total assets in foreign securities that are held di-
rectly. The 10% limit does not apply to foreign securities held through Deposi-
tory Receipts which are traded in the United States or to commercial paper and
certificates of deposit issued by foreign banks. The Subadviser  serves the
Fund pursuant to a Subadvisory Agreement with the Manager (the "Subadvisory
Agreement"), dated June 1, 1994. The Subadvisory Agreement provides that the
Subadviser provides investment management services with respect to the Qualify-
ing Assets, including investment research, advice and supervision, determines
which securities will be purchased or sold, makes purchases and sales on behalf
of the Fund and determines how voting and other rights with respect to securi-
ties held by the Fund shall be exercised, subject in each case to the control
of the Board of Directors and in accordance with the Fund's investment objec-
tives, policies and principles. For this service, the Subadviser receives a fee
from the Manager, payable monthly equal to .75% per annum of the average
monthly net Qualifying Assets of the Fund, i.e., the Qualifying Assets less any
related liabilities as designated by the Manager. For the period June 1, 1994
through December 31, 1994, the Fund did not require the services of the
Subadviser.     
   
  The Subadviser was founded in 1991 as a joint venture between the Manager and
Henderson International, Inc., a controlled affiliate of Henderson Administra-
tion Group plc. The Subadviser, headquartered in New York, was created to pro-
vide international and global investment advice to institutional and individual
investors and investment companies in the United States. The Subadviser cur-
rently serves as subadviser to Seligman Capital Fund, Inc., Seligman Common
Stock Fund, Inc., Seligman Frontier Fund, Inc., Seligman Growth Fund, Inc., Se-
ligman Henderson Global Fund Series, Inc., Seligman Income Fund, Inc., the
Global Portfolio and Global Smaller Companies Portfolio of Seligman Portfolios,
Inc., Tri-Continental Corporation, the International Equity Fund of The Compass
Capital Group, and the Seligman Henderson International Small Capital Portfolio
and Seligman Henderson International Equity Portfolio of the American Skandia
Trust. The address of the Subadviser is 100 Park Avenue, New York, NY 10017.
    
          
  PORTFOLIO MANAGER. Paul H. Wick is a Managing Director of the Manager and
Vice President and Portfolio Manager of the Fund, Seligman Frontier Fund, Inc.,
and the Seligman Communications and Information Portfolio and the Seligman
Frontier Portfolio of Seligman Portfolios, Inc. Mr. Wick also co-manages Selig-
man Henderson Global Technology Fund, a series of Seligman Henderson Global
Fund Series, Inc. Mr. Wick joined the Manager in 1987 as an Associate, Invest-
ment Research, and from April 1989 to December 1989 was co-manager of Seligman
High-Yield Bond Series. He was promoted to Managing Director on January 1,
1995.     
   
  Mr. Brian Ashford-Russell will be responsible for the Subadviser's day-to-day
investment activity with respect to the Fund to the extent there are Qualifying
Assets. Mr. Ashford-Russell has been a Portfolio Manager with Henderson Admin-
istration Group plc since February 1993. He was previously a Portfolio Manager
with Touche Remnant & Co.

  PORTFOLIO TRANSACTIONS. The Management Agreement and Subadvisory Agreement
recognize that in the purchase and sale of portfolio securities, the Manager
and Subadviser will seek the most favorable price and execution, and, consis-
tent with that policy, may give consideration to the research, statistical and
other services furnished by brokers or dealers to the Manager and Subadviser.
The use of brokers who provide investment and market research and securities
and economic analysis may result in higher brokerage charges than the use of
brokers selected on the basis of the most favorable brokerage commission rates
and research and analysis received may be useful to the Manager and Subadviser
in connection with its services to other clients as well as to the Fund. In
over-the-counter markets, orders are placed with responsible primary market
makers unless a more favorable execution or price is believed to be obtainable.
       
  Consistent with the rules of the National Association of Securities Dealers,
Inc., and subject to seeking the most favorable price and execution available
and such other policies as the Directors may determine, the Manager and
Subadviser may consider sales of shares of the Fund and, if permitted by appli-
cable laws, may consider sales of shares of the other funds in the Seligman
Group as a factor in the selection of brokers or dealers to execute portfolio
transactions for the Fund.     
          
  PORTFOLIO TURNOVER. A change in securities held by the Fund is known as
"portfolio turnover" which may result in the payment by the Fund of dealer
spreads or underwriting commissions and other transaction costs on the sale of
securities as well as on the reinvestment of the proceeds in other securities.
Although it is the policy of the Fund to hold securities for investment,
changes in the securities held by the Fund will be made from time to time when
the Manager and Subadviser believe such changes will strengthen the Fund's
portfolio. The portfolio turnover of the Fund may exceed 100% and has done so
in prior years.     
 
PURCHASE OF SHARES
 
  Seligman Financial Services, Inc. ("SFSI"), an affiliate of the Manager, acts
as general distributor of the Fund's shares. Its address is 100 Park Avenue,
New York, New York 10017.
 
  The Fund issues two classes of shares: Class A shares are sold to investors
choosing the initial sales load alternative; and Class D shares are sold to in-
vestors choosing no initial sales load, a higher distribution fee and a CDSL on
redemptions within one year of purchase. See "Alternative Distribution System"
above.
 
  Shares of the Fund may be purchased through any authorized investment dealer.
All orders will be executed at the net asset value per share next computed af-
ter receipt of the purchase order plus, in the case of Class A shares, a sales
load which, except for shares purchased under one of the reduced sales load
plans, will vary with the size of the purchase as shown in the schedule under
"Class A Shares--Initial Sales Load" below.
   
  The Fund will discontinue indefinitely the sale of its shares to new invest-
ors, including, subject to the exceptions in this paragraph, IRAs and retire-
ment plans, at the close of business on June 30, 1995. The Fund will continue
to accept additional investments from existing shareholders, and will continue
to reinvest dividends and capital gains distributions with respect to the ac-
counts of existing shareholders who have elected those options. The Fund will
also continue to sell shares to (i) group retirement plans (including 401(k)
plans) that have been established by June 30, 1995 for which funding has begun
no later than September 30, 1995, and (ii) IRAs established via a transfer-of-
assets postmarked by June 30. The decision to discontinue sales to new invest-
ors reflects the manager's belief that unrestrained growth in the Fund's assets
might impair the Fund's investment flexibility and would not be in the best in-
terests of     
                                       9
<PAGE>
 
   
shareholders. The Fund may recommence the sale of its shares to new investors
if it is deemed by the Fund's Board of Directors to be in the best interests of
shareholders.     
   
   THE MINIMUM AMOUNT FOR INITIAL INVESTMENT IN THE FUND IS $1,000 (EXCEPT FOR
AN ACCOUNT BEING ESTABLISHED PURSUANT TO THE INVEST-A-CHECK (R) SERVICE); SUB-
SEQUENT INVESTMENTS MUST BE IN THE MINIMUM AMOUNT OF $100 (EXCEPT FOR INVEST-
MENT OF DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS). THE FUND RESERVES THE RIGHT
TO RETURN INVESTMENTS WHICH DO NOT MEET THESE MINIMUMS.     
   
  Orders received by an authorized dealer before the close of business on the
New York Stock Exchange ("NYSE") (4:00 p.m. Eastern time) and accepted by SFSI
before the close of business (5:00 p.m. Eastern time) on the same day will be
executed at the Fund's net asset value determined as of the close of the NYSE
on that day plus, in the case of Class A shares, the applicable sales load. Or-
ders accepted by dealers after the close of the NYSE, or received by SFSI after
the close of business, will be executed at the Fund's net asset value as next
determined plus, in the case of Class A shares, the applicable sales load. The
authorized dealer through which a shareholder purchases shares is responsible
for forwarding the order to SFSI promptly.     
   
  Payment for dealer purchases may be made by check or by wire. To wire pay-
ment, dealer orders must first be placed through SFSI's order desk and assigned
a purchase confirmation number. Funds in payment of the purchase may then be
wired to Mellon Bank, N.A., ABA #043000261, A/C Seligman Communications & In-
formation Fund, Inc. (A or D), A/C #107-1011. WIRE TRANSFERS MUST INCLUDE THE
PURCHASE CONFIRMATION NUMBER AND CLIENT ACCOUNT REGISTRATION AND ACCOUNT NUM-
BER. Persons other than dealers who wish to wire payment should contact Selig-
man Data Corp. for specific wire instructions. Although the Fund makes no
charge for this service, the transmitting bank may impose a wire service fee.
       
  Existing shareholders may purchase additional shares at any time through any
authorized dealer or by sending a check payable to the "Seligman Group of Mu-
tual Funds" directly to P.O. BOX 3936, NEW YORK, NY 10008-3936. Checks for in-
vestment must be in U.S. dollars drawn on a domestic bank. The check should in-
clude the shareholder's name, address, account number, name of Fund and class
of shares. If a shareholder does not indicate the required information, Selig-
man Data Corp. will seek further clarification and may be forced to return the
check to the shareholder. If only the class designation is missing, the invest-
ment will automatically be made in Class A shares. Orders sent directly to Se-
ligman Data Corp. will be executed at the Fund's net asset value next deter-
mined after the order is accepted plus, in the case of Class A shares, the ap-
plicable sales load.     
   
  Seligman Data Corp. will charge a $10.00 service fee for checks returned to
it marked "unpaid." This charge may be deducted from the account that requested
the purchase. For the protection of the Fund and its shareholders, no redemp-
tion proceeds will be remitted to a shareholder with respect to shares pur-
chased by check (unless certified) until Seligman Data Corp. receives notice
that the check has cleared, which may be up to 15 days from the credit of the
shares to the shareholder's account.     
   
  VALUATION. The net asset value of the Fund's shares is determined each day,
Monday through Friday, as of the close of trading on the NYSE (usually 4:00
p.m. Eastern time) on each day that the NYSE is open for business. Net asset
value is calculated separately for each class. Securities traded on a U.S. or
foreign exchange or over-the-counter market are valued at the last sales price
on the primary exchange or market on which they are traded. United Kingdom se-
curities and securities for which there are no recent sales transactions are
valued based on quotations provided by primary market makers in such securi-
ties. Any securities for which recent market quotations are not readily avail-
able are valued at fair value determined in accordance with procedures approved
by the Board of Directors. Short-term holdings maturing in 60     
 
                                       10
<PAGE>
 
   
days or less are generally valued at amortized cost if their original maturity
was 60 days or less. Short-term holdings with more than 60 days remaining to
maturity will be valued at current market value until the 61st day prior to ma-
turity, and will then be valued on an amortized cost basis based on the value
as of such date unless the Board determines that amortized cost value does not
represent fair market value.     
   
  Although the legal rights of Class A and Class D shares are substantially
identical, the different expenses borne by each class will result in different
net asset values and dividends. The net asset value of Class D shares will gen-
erally be lower than the net asset value of Class A shares as a result of the
larger distribution fee charged to Class D shares. In addition, net asset value
per share of the two classes will be affected to the extent any other class ex-
pense differs among classes.     
 
  CLASS A SHARES--INITIAL SALES LOAD. Class A shares are subject to an initial
sales load which varies with the size of the purchase as shown in the schedule
below, and an annual service fee of up to .25% of the average daily net asset
value of Class A shares. See "Administration, Shareholder Services and Distri-
bution Plan" below.

  REDUCED SALES LOADS. Reductions in sales loads 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 purchasing securities for their own
account, or a trustee or other fiduciary purchasing for a single fiduciary ac-
count or single trust. Purchases made by a trustee or other fiduciary for a fi-
duciary account may not be aggregated with purchases made on behalf of any
other fiduciary or individual account.
          
. 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 funds in
the Seligman Group that are sold with a sales load reaches levels indicated in
the above sales load schedule.     
   
. THE RIGHT OF ACCUMULATION allows an investor to combine the amount being in-
vested in Class A shares of the other mutual funds in the Seligman Group sold
with a sales load with the total net asset value of shares of those funds al-
ready owned that were sold with a sales load and the total net asset value of
shares of Seligman Cash Management Fund that were acquired by the investor
through an exchange of shares of another mutual fund in the Seligman Group on
which there was a sales load to determine reduced sales loads in accordance
with the sales load schedule. An investor or a dealer purchasing shares on be-
half of an investor must indicate that the investor has existing accounts when
making investments or opening new accounts.     
   
. A LETTER OF INTENT allows an investor to purchase Class A shares over a 13-
month period at reduced sales loads, based upon the total amount the investor
intends to purchase, plus the total net asset value of shares of the other mu-
tual funds in the Seligman Group already owned that were sold with a sales load
and the total net asset value of shares of Seligman Cash Management Fund that
were acquired through an exchange of shares of another mutual fund in the Se-
ligman Group on which there was a sales load. An investor or a dealer purchas-
ing shares on behalf of an     
 
                                       11
<PAGE>
 
   
investor must indicate that the investor has existing accounts when making in-
vestments or opening new accounts. For more information concerning terms of
Letters of Intent, see "Terms and Conditions" on page 24.     
 
  SPECIAL PROGRAMS. The Fund may sell Class A shares at net asset value to
present and retired directors, trustees, officers, employees (and their
spouses and minor children) of the Fund, the other investment companies in the
Seligman Group, the Manager and other companies affiliated with the Manager.
Such sales also may be made to employee benefit and thrift plans for such per-
sons and to any investment advisory, custodial, trust or other fiduciary ac-
count managed or advised by the Manager or any affiliate.
   
  Class A shares also may be issued without a sales load in connection with
the acquisition of cash and securities owned by other investment companies and
personal holding companies; to any registered unit investment trust which is
the issuer of periodic payment plan certificates, the net proceeds of which
are invested in Fund shares; to separate accounts established and maintained
by an insurance company which are exempt from registration under Section
3(c)(11) of the 1940 Act; to registered representatives and employees (and
their spouses and minor children) of any dealer that has a sales agreement
with SFSI; to shareholders of mutual funds with objectives and policies simi-
lar to the Fund who purchase shares with redemption proceeds of such funds; to
financial institution trust departments; to registered investment advisers ex-
ercising discretionary investment authority with respect to the purchase of
Fund shares; to accounts of financial institutions or broker/dealers that
charge account management fees, provided the Manager or one of its affiliates
has entered into an agreement with respect to such accounts; pursuant to spon-
sored 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; and to "eligible employee benefit
plans" of employers who have at least 2,000 U.S. employees to whom such a plan
is made available and, regardless of the number of employees, if such plan is
established and maintained by any dealer that has a sales agreement with SFSI.
"Eligible employee benefit plans" 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 sys-
tem of plan funding or other system acceptable to Seligman Data Corp.     
 
  CLASS D SHARES. Class D shares are sold without an initial sales load but
are subject to CDSL if the shares are redeemed within one year, an annual dis-
tribution fee of up to .75 of 1% and an annual service fee of up to .25 of 1%
of the average daily net asset value of Class D shares. SFSI will make a 1%
payment to dealers in respect of purchases of Class D shares.
 
  A CDSL will be imposed on any redemption of Class D shares which were pur-
chased during the preceding twelve months; however, no such charge will be im-
posed on shares acquired through the investment of dividends or distributions
from any Class D shares within the Seligman Group. The amount of any CDSL will
be paid to and retained by SFSI.
 
  To minimize the application of CDSL to a redemption, shares acquired pursu-
ant to the investment of dividends and distributions will be redeemed first;
followed by shares purchased at least one year prior to the redemption. Shares
held for the longest period of time within the applicable one year period will
then be redeemed. Additionally, for those shares determined to be subject to
the CDSL, the application of the 1% CDSL will be made to the current net asset
value or original purchase price, whichever is less.
 
  For example, assume an investor purchased 100 shares in January at a price
of $10.00 per share. During the first year, 5 additional shares were acquired
through investment of dividends and distributions. In January of the following
year, an additional 50 shares are purchased at a price of $12.00 per share. In
March of that year, the investor chooses to redeem $1,500.00 from the account
which now holds 155 shares with a total value of $1,898.75 ($12.25 per
 
                                      12

share). The CDSL for this transaction would be calculated as follows:

</TABLE>    
 
  For federal income tax purposes, the amount of the CDSL will reduce the gain
or increase the loss, as the case may be, on the amount recognized on the re-
demption of shares.
 
  The CDSL will be waived or reduced in the following instances:
 
  (a) on redemptions following the death or disability of a shareholder, as de-
fined in section 72(m)(7) of the Internal Revenue Code of 1986, as amended (the
"Code"); (b) in connection with (i) distributions from retirement plans quali-
fied under section 401(a) of the 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), (ii) dis-
tributions from a custodial account under Code section 403 (b)(7) or an indi-
vidual retirement account ("IRA") due to death, disability, or attainment of
age 59 1/2, and (iii) a tax-fee return of an excess contribution to an IRA; (c)
in whole or in part, in connection with shares sold to current and retired Di-
rectors of the Fund; (d) 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 shares of any reg-
istered investment management company; (e) pursuant to an automatic cash with-
drawal service; (f) in connection with the redemption of Class D shares of the
Fund if it is combined with another mutual fund in the Seligman Group, or an-
other similar reorganization transaction; and (g) in connection with the Fund's
right to redeem or liquidate an account that holds below a certain minimum num-
ber or dollar amount of shares (currently $500).
 
  If, with respect to a redemption of any Class D shares sold by a dealer, the
CDSL is waived because the redemption qualifies for a waiver as set forth
above, the dealer shall remit to SFSI promptly upon notice an amount equal to
the 1% payment or a portion of the 1% payment paid on such shares.
   
  SFSI may from time to time assist dealers by, among other things, providing
sales literature to, and holding informational programs for the benefit of,
dealers' registered representatives. Dealers may limit the participation of
registered representatives in such informational programs by means of sales in-
centive programs which may require the sale of minimum dollar amounts of shares
of the mutual funds in the Seligman Group. SFSI may from time to time pay a bo-
nus or other incentive to dealers that sell shares of the Seligman Mutual
Funds. In some instances, these bonuses or incentives may be offered only to
certain dealers which employ registered representatives who have sold or may
sell a significant amount of shares of the Fund and/or certain other funds man-
aged by the Manager during a specified period of time. Such bonus or other in-
centive may take the form of payment for travel expenses, including lodging,
incurred in connection with trips taken by qualifying registered representa-
tives and members of their families to places within or outside the United
States. The cost of SFSI of such promotional activities and payments shall be
consistent with the rules of the National Association of Securities Dealers,
Inc., as then in effect.

TELEPHONE TRANSACTIONS     
   
  A shareholder whose account has either an individual or joint tenancy regis-
tration may elect to effect the following transactions via telephone by com-
pleting the Telephone Service Election portion of the Account Application or a
separate Telephone Service Election Form: (i) redemption of Fund shares, (ii)
exchange of Fund shares for shares of another Seligman Mutual Fund, (iii)
change of a dividend and/or capital gain distribution option, and (iv) change
of address. IRA accounts may only elect to effect exchanges or address changes.
By completing the appropriate section of the Account Application or separate
Election Form, all Seligman Mutual Funds with the same account number (i.e.,
registered in exactly the same names), including any new fund in which the
shareholder invests in the future, will automatically have telephone services.
All telephone transactions are effected through Seligman Data Corp. at (800)
221-2450.     
   
  For accounts registered as joint tenancies, each joint tenant, by electing
telephone transaction services, authorizes each of the other tenants to effect
telephone transactions on his or her behalf.     
   
  During times of drastic economic or market changes, a shareholder may experi-
ence difficulty in contacting Seligman Data Corp. to request a redemption or
exchange of Fund shares. In these circumstances, the shareholder should con-
sider using other redemption or exchange procedures. (See "Redemption Of
Shares" below.) Use of these other redemption or exchange procedures will re-
sult in the redemption request being processed at a later time than if tele-
phone transactions had been used, and the Fund's net asset value may fluctuate
during such periods.     
   
  The Fund and Seligman Data Corp. will employ reasonable procedures to confirm
that instructions communicated by telephone are genuine. These will include:
recording all telephone calls requesting account activity, requiring that the
caller provide certain requested personal and/or account information at the
time of the call for the purpose of establishing the caller's identity, and
sending a written confirmation of redemptions, exchanges or address changes to
the address of record each time activity is initiated by telephone. As long as
the Fund and Seligman Data Corp. follow instructions communicated by telephone
that were reasonably believed to be genuine at the time of their receipt, nei-
ther they nor any of their affiliates will be liable for any loss to the share-
holder caused by an unauthorized transaction. Shareholders are, of course, un-
der no obligation to apply for telephone transaction services. In any instance
where the Fund or Seligman Data Corp. is not reasonably satisfied that instruc-
tions received by telephone are genuine, the requested transaction will not be
executed, and neither they nor any of their affiliates will be liable for any
losses which may occur due to a delay in implementing the transaction. If the
Fund or Seligman Data Corp. does not follow the procedures described above, the
Fund or Seligman Data Corp. may be liable for any losses due to unauthorized or
fraudulent instructions. Telephone services must be effected through a repre-
sentative of Seligman Data Corp., i.e., requests may not be communicated via
Seligman Data Corp.'s automated telephone answering system. Telephone transac-
tion services may be terminated by a shareholder at any time by sending a writ-
ten request to Seligman Data Corp. Written acknowledgment of termination of
telephone transaction services will be sent to the shareholder.     
 
REDEMPTION OF SHARES
   
  A shareholder may redeem shares held in book credit form without charge (ex-
cept a CDSL, if applicable) at any time by SENDING A WRITTEN REQUEST to
Seligman Data Corp., 100 Park Avenue, New York, New York 10017. The redemption
request must be signed by all persons in whose name the shares are registered.
A shareholder may redeem shares that are not in book credit form by surrender-
ing certificates in proper form to the same address. Certificates should be
sent by registered mail. Share certificates must be endorsed for transfer or
accompanied by an endorsed stock power signed by all share owners exactly as
their name(s) appear(s) on the account registration.     
 
                                       14

The shareholder's letter of instruction or endorsed stock power should specify
the account number, class of shares (A or D) and the number of shares or dollar
amount to be redeemed. The Fund cannot accept conditional redemption requests.
If the redemption proceeds are (i) $50,000 or more, (ii) to be paid to someone
other than the shareholder of record (regardless of the amount) or (iii) to be
mailed to other than the address of record (regardless of the amount), the sig-
nature(s) of the shareholder(s) must be guaranteed by an eligible financial in-
stitution including, but not limited to, the following: banks, trust companies,
credit unions, securities brokers and dealers, savings and loan associations
and participants in the Securities Transfer Association Medallion Program
(STAMP), the Stock Exchanges Medallion Program (SEMP) or the New York Stock Ex-
change Medallion Signature Program (MSP). The Fund reserves the right to reject
a signature guarantee where it is believed that the Fund will be placed at risk
by accepting such guarantee. A signature guarantee is also necessary in order
to change the account registration. Notarization by a notary public is not an
acceptable signature guarantee. ADDITIONAL DOCUMENTATION MAY ALSO BE REQUIRED
BY SELIGMAN DATA CORP. IN THE EVENT OF A REDEMPTION BY CORPORATIONS, EXECUTORS,
ADMINISTRATORS, TRUSTEES, CUSTODIANS OR RETIREMENT PLANS. FOR FURTHER INFORMA-
TION WITH RESPECT TO NECESSARY REDEMPTION REQUIREMENTS, PLEASE CONTACT THE
SHAREHOLDER SERVICES DEPARTMENT OF SELIGMAN DATA CORP. FOR ASSISTANCE. In the
case of Class A shares, and in the case of Class D shares redeemed after one
year, a shareholder will receive the net asset value per share next determined
after receipt of a request in good order. If Class D shares are redeemed within
one year of purchase, a shareholder will receive the net asset value per share
next determined after receipt of a request in good order, less a CDSL of 1% as
described under "Purchase Of Shares--Class D Shares" above.     
   
  A shareholder also may "sell" shares to the Fund through an investment dealer
and, in that way, be certain, providing the order is timely, of receiving the
net asset value established at the end of the day on which the dealer is given
the repurchase order. The Fund makes no charge for this transaction, but the
dealer may charge you a service fee. "Sell" or repurchase orders received from
an authorized dealer before the close of the NYSE and received by SFSI, the re-
purchase agent, before the close of business on the same day will be executed
at the net asset value per share determined as of the close of the NYSE on that
day. Repurchase orders received from authorized dealers after the close of the
NYSE or not received by SFSI prior to the close of business, will be executed
at the net asset value determined as of the close of the NYSE on the next trad-
ing day. Shares held in a "street name" account with a broker/dealer may be
sold to the Fund only through a broker/dealer.     
   
  TELEPHONE REDEMPTIONS. Telephone redemptions of uncertificated shares may be
made in an amount of up to $50,000 per day, per account. One telephone redemp-
tion request per day is permitted. Telephone redemption requests must be re-
ceived by Seligman Data Corp. at (800) 221-2450 between 8:30 a.m. and 4:00 p.m.
Eastern time, on any business day and will be processed as of the close of
business on that day. Redemption requests by telephone will not be accepted
within 30 days following an address change. Keogh Plans, IRAs or other retire-
ment plans are not eligible for telephone redemptions. The Fund reserves the
right to suspend or terminate its telephone redemption service at any time
without notice.     
   
  For more information about telephone redemptions, including the procedure for
electing such service and the circumstances under which shareholders may bear
the risk of loss for a fraudulent transaction, see "Telephone Transactions"
above.     
   
  GENERAL. Whether shares are redeemed or repurchased, a check for the proceeds
will be sent to the address of record within seven calendar days after accept-
ance of the redemption or repurchase order and will be made payable to all of
the registered owners on the Account. The Fund will not permit redemp     
 
                                       15
<PAGE>
 
   
tions of shares purchased by check (unless certified) until Seligman Data
Corp. receives notice that the check has cleared, which may be up to 15 days
from the credit of the shares to the shareholder's account. The proceeds of a
redemption or repurchase may be more or less than the shareholder's cost.     
   
  The Fund reserves the right to redeem shares owned by a shareholder whose
investment in the Fund has a value of less than a minimum amount specified by
the Fund's Board of Directors, which is presently $500. Shareholders are sent
a notice before the redemption is processed stating that the value of their
investment in the Fund is less than the specified minimum and that they have
sixty days to make an additional investment.     
   
  REINSTATEMENT PRIVILEGE. If a shareholder redeems Class A shares and then
decides not to redeem them, or to shift your investment to one of the other
mutual funds in the Seligman Group, the shareholder may, within 120 calendar
days of the date of redemption, use all or any part of the proceeds of the re-
demption to reinstate, free of sales load, all or any part of the investment
in shares of the Fund or in shares of any of the other mutual funds in the Se-
ligman Group. If a shareholder redeems Class D shares and the redemption was
subject to a CDSL, the shareholder may reinstate the investment in shares of
the same class of the Fund or in any of the other mutual funds in the Seligman
Group within 120 calendar days of the date of redemption and receive a credit
for the CDSL paid. Such investment will be reinstated at the net asset value
per share established as of the close of the NYSE on the day the request is
received. Seligman Data Corp. must be informed that the purchase represents a
reinstated investment. REINSTATED SHARES MUST BE REGISTERED EXACTLY AND BE OF
THE SAME CLASS AS THE SHARES PREVIOUSLY REDEEMED.     
 
  Generally, exercise of the Reinstatement Privilege does not alter the Fed-
eral income tax status of any capital gain realized on a sale of Fund shares,
but to the extent that any shares are sold at a loss and the proceeds are re-
invested in shares of the same Fund, some or all of the loss will not be al-
lowed as a deduction, depending upon the percentage of the proceeds reinvest-
ed.
 
ADMINISTRATION, SHAREHOLDER SERVICES AND DISTRIBUTION PLAN
 
  Under the Fund's Administration, Shareholder Services and Distribution Plan
(the "Plan"), the Fund may pay to SFSI an administration, shareholder services
and distribution fee in respect of the Fund's Class A and Class D shares. Pay-
ments under the Plan may include, but are not limited to: (i) compensation to
securities dealers and other organizations ("Service Organizations") for pro-
viding distribution assistance with respect to assets invested in the Fund,
(ii) compensation to Service Organizations for providing administration, ac-
counting 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 dis-
tribution of such promotional materials and prospectuses to prospective in-
vestors and defraying SFSI's costs incurred in connection with its marketing
efforts with respect to shares of the Fund. The Manager, in its sole discre-
tion, may also make similar payment to SFSI from its own resources, which may
include the management fee that the Manager receives from the Fund.
 
  Under the Plan, the Fund reimburses SFSI for its expenses with respect to
Class A shares at an annual rate of up to .25% of the average daily net asset
value of Class A shares. It is expected that the proceeds from the fee in re-
spect of Class A shares will be used primarily to compensate Service Organiza-
tions which enter into agreements with SFSI. Such Service Organ-izations will
receive from SFSI 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
 
                                      16
<PAGE>
 
personal service and/or the maintenance of shareholder accounts. The fee pay-
able from time to time is, within such limit, determined by the Directors of
the Fund.
   
  The Plan, as it relates to Class A shares, was approved by shareholders on
November 23, 1992 and became effective on January 1, 1993. The Plan is reviewed
by the Directors annually. The total amount paid for the year ended December
31, 1994 in respect of the Fund's Class A shares pursuant to the Plan was equal
to .21% of the Class A shares' average daily net assets.     
 
  Under the Plan, the Fund reimburses SFSI for its expenses with respect to
Class D shares at an annual rate of up to 1% of the average daily net asset
value of the Class D shares. Proceeds from the Class D distribution fee are
used primarily to compensate Service Organizations for administration, share-
holder services and distribution assistance (including a continuing fee of up
to .25% on an annual basis of the average daily net asset value of Class D
shares attributable to particular Service Organizations for providing personal
service and/or the maintenance of shareholder accounts) and will initially be
used by SFSI to defray the expense of the 1% payment made by it to Service Or-
ganizations at the time of the sale of Class D shares. The amounts expended by
SFSI in any one year upon the initial purchase of Class D shares may exceed the
amounts received by it from Plan payments retained. Expenses of administration,
shareholder services and distribution of Class D shares in one fiscal year of
the Fund may be paid from Class D Plan fees received from the Fund in any other
fiscal year.
   
  The Plan, as it relates to Class D shares, was approved by the Directors on
March 18, 1993 and became effective May 1, 1993. The Plan is reviewed by the
Directors annually. The total amount paid for the year ended December 31, 1994
by the Fund's Class D shares pursuant to the Plan was 1% per annum of the aver-
age daily net assets of Class D shares.     
   
  Seligman Services, Inc. ("SSI"), an affiliate of the Manager, is a limited
purpose broker/dealer. SSI shall act as broker/dealer of record for most share-
holder accounts that do not have a designated broker/dealer of record, includ-
ing all such shareholder accounts established after April 1, 1995 and will re-
ceive compensation for providing personal service and account maintenance to
its accounts of record.     
 
EXCHANGE PRIVILEGE
   
  A shareholder of the Fund may, without charge, exchange at net asset value
any or all of an investment in the Fund for shares of any of the other mutual
funds in the Seligman Group. Exchanges may be made by mail, or by telephone, if
telephone services are elected by the shareholder.     
   
  Class A and Class D shares may be exchanged only for Class A and Class D
shares, respectively, of another mutual fund in the Seligman Group on the basis
of relative net asset value.     
 
  If Class D shares that are subject to a CDSL are exchanged for Class D shares
of another fund, for purposes of assessing the CDSL payable upon disposition of
the exchanged Class D shares, the one year holding period shall be reduced by
the holding period of the original Class D shares.
 
  The mutual funds in the Seligman Group available under the Exchange Privilege
are:
 
  . SELIGMAN CAPITAL FUND, INC: seeks aggressive capital appreciation. Current

  All permitted exchanges will be based on the then current net asset values
of the respective funds. Telephone requests for exchanges must be received be-
tween 8:30 a.m. and 4:00 p.m. Eastern time, on any business day, by Seligman
Data Corp. at (800) 221-2450, and will be processed as of the close of busi-
ness on that day. The registration of an account into which an exchange is
made must be identical to the registration of the account from which shares
are exchanged. When establishing a new account by an exchange of shares, the
shares being exchanged must have a value of at least the minimum initial in-
vestment required by the mutual fund into which the exchange is being made.
The method of receiving distributions, unless otherwise indicated, will be
carried over to the new Fund account. Account services, such as Invest-A-
Check (R) Service, Directed Dividends and Automatic Cash Withdrawal Service
will not be carried over to the new Fund account unless specifically requested
and permitted by the new Fund. Exchange orders may be placed to effect an ex-
change of a specific number of shares, an exchange of shares equal to a spe-
cific dollar amount or an exchange of all shares held. Shares for which cer-
tificates have been issued may not be exchanged via telephone and may be ex-
changed only upon receipt of a written exchange request together with certifi-
cates representing shares to be exchanged in form for transfer.     
   
  Telephone exchanges are only available to shareholders whose accounts are
registered individually, as joint tenancies or IRAs. The Exchange Privilege
via mail is generally applicable to investments in an IRA and other retirement
plans, although some restrictions may apply and may be applicable to other mu-
tual funds in the Seligman Group that may be organized by the Manager in the
future. The terms of the exchange offer described herein may be modified at
any time;     
 
                                      18

and not all of the mutual funds in the Seligman Group are available to resi-
dents of all states. Before making any exchange a shareholder should contact an
authorized investment dealer or Seligman Data Corp. to obtain prospectuses of
any of the mutual funds in the Seligman Group.     
   
  A broker/dealer of record will be able to effect exchanges on behalf of a
shareholder only if the broker/dealer has entered into a Telephone Exchange
Agreement with SFSI wherein the broker/dealer must agree to indemnify SFSI and
the mutual funds in the Seligman Group from any loss or liability incurred as a
result of the acceptance of telephone exchange orders.     
   
  Written confirmation of all exchanges will be forwarded to the shareholder to
whom the exchanged shares are registered and a duplicate confirmation will be
sent to the dealer of record listed on the account. SFSI reserves the right to
reject a telephone exchange request. The Fund reserves the right to reject any
telephone requests for transactions with a share value exceeding $250,000. Any
rejected telephone exchange order may be processed by mail. For more informa-
tion about telephone exchanges, including the procedure for electing such serv-
ice and the circumstances under which shareholders may bear the risk of loss
for a fraudulent transaction, see "Telephone Transactions" above.     
 
  Exchanges of shares are sales and may result in a gain or loss for Federal
income tax purposes.
   
FURTHER INFORMATION ABOUT TRANSACTIONS IN THE FUND     
   
  Because excessive trading (including short-term, "market timing" trading) can
hurt the Fund's performance, the Fund may refuse any exchange (1) from any
shareholder account from which there have been two exchanges in the preceding
three month period, or (2) where the exchanged shares equal in value the lesser
of $1,000,000 or 1% of the Fund's net assets. The Fund may also refuse any ex-
change or purchase order from any shareholder account if the shareholder or the
shareholder's broker/dealer has been advised that previous patterns of pur-
chases and redemptions or exchanges have been considered excessive. Accounts
under common ownership or control, including those with the same taxpayer ID
number and those administered so as to redeem or purchase shares based upon
certain predetermined market indicators, will be considered one account for
this purpose. Additionally, the Fund reserves the right to refuse any order for
the purchase of shares.     
 
DIVIDENDS AND DISTRIBUTIONS
 
  The Fund's net investment income, if any, is paid to shareholders in divi-
dends in December. Payments vary in amount depending on income received from
portfolio securities and the costs of operations. The Fund distributes substan-
tially all of any taxable net long-term and short-term gain realized on invest-
ments to shareholders at least annually; such distributions will generally be
taxable to shareholders in the year in which they are declared by the Fund if
paid before February 1 of the following year.
   
  Shareholders may elect: (1) to receive both dividends and gain distributions
in shares; (2) to receive dividends in cash and gain distributions in shares;
(3) to receive both dividends and gain distributions in cash. In the case of
prototype retirement plans, dividends and gain distributions are reinvested in
additional shares. Unless another election is made, dividends and capital gains
distributions will be credited to shareholder accounts in additional shares.
Shares acquired through a dividend or gain distribution and credited to a
shareholder's account are not subject to an initial sales load or a CDSL. Divi-
dends and gain distributions paid in shares are invested at the net asset value
on the ex-dividend date. Shareholders may elect to change their dividend and
gain distribution options by writing Seligman Data Corp. at the address listed
below. If the shareholder has elected telephone services, changes may also be
telephoned to Seligman Data Corp. between 8:00 a.m. and 5:30 p.m. Eastern     
 
                                       19

time, by either the shareholder or the broker/dealer of record on the account.
For information about electing telephone services, see "Telephone Transac-
tions." These elections must be received by Seligman Data Corp. before the rec-
ord date for the dividend or distribution in order to be effective for such
dividend or distribution, otherwise payment will be made in accordance with the
current option on the shareholder's account.     
   
  The per share dividends from net investment income on Class D shares will be
lower than the per share dividends on Class A shares as a result of the higher
distribution fee applicable with respect to Class D shares. Per share dividends
of the two classes may also differ as a result of differing class expenses.
Distributions of net capital gains, if any, will be paid in the same amount for
Class A and Class D shares. See "Purchase Of Shares--Valuation."     
   
  Shareholders exchanging shares of a mutual fund for shares of another mutual
fund in the Seligman Group will continue to receive dividends and gains as
elected prior to such exchange unless otherwise specified. In the event that a
shareholder redeems all shares in an account between the record date and the
payable date, the value of dividends or gain distributions declared will be
paid in cash regardless of the existing election.     
 
FEDERAL INCOME TAXES
   
  The Fund intends to continue to qualify as a regulated investment company un-
der the Internal Revenue Code of 1986, as amended. For each year so qualified,
the Fund will not be subject to Federal income taxes on its net investment in-
come and capital gains, if any, realized during any taxable year, which it dis-
tributes 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 the shareholders, whether re-
ceived in cash or reinvested in additional shares, and, to the extent desig-
nated 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 compa-
ny, they are eligible, subject to certain restrictions, for the 70% dividends
received deduction for corporations.
   
  Distributions of net capital gain, i.e., the excess of net long-term capital
gains over any net short-term losses, are taxable as long-term capital gain,
whether received in cash or invested in additional shares, regardless of how
long shares have been held by the shareholders; such distributions are not eli-
gible for the dividends received deduction allowed to corporate shareholders.
       
  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. However, if shares on
which a long-term capital gain distribution has been received are subsequently
sold or redeemed and such shares have been held for six months or less, any
loss realized will be treated as long-term capital loss to the extent that it
offsets the long-term capital gain distribution. In addition, no loss will be
allowed on the sale or other disposition of shares of the Fund if, within a pe-
riod beginning 30 days before the date of such sale or disposition and ending
30 days after such date, the holder acquires (such as through dividend rein-
vestment) 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 load incurred
in acquiring such shares to the extent of any subsequent reduction of the sales
load by reason of the Exchange or Reinstatement Privilege offered by the Fund.
Any sales load not taken into account in determining the tax basis of shares
sold or
 
                                       20
<PAGE>
 
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 a basis such that such income or gain is not taxable to share-
holders in the calendar year in which it was earned. Furthermore, dividends de-
clared 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 De-
cember. Under this rule, therefore, shareholders may be taxed in one year on
dividends or distributions actually received in January of the following year.
    
  Shareholders are urged to consult their tax advisers concerning the effect of
Federal income taxes in their individual circumstances.
 
  UNLESS A SHAREHOLDER INCLUDES A CERTIFIED TAXPAYER IDENTIFICATION NUMBER (SO-
CIAL 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 U.S. 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 INTER-
NAL 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 DEBITED FROM THE SHAREHOLDER'S ACCOUNT AND OFFSET AGAINST ANY UN-
DISTRIBUTED DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS. THE FUND ALSO RESERVES
THE RIGHT TO CLOSE ANY ACCOUNT WHICH DOES NOT HAVE A CERTIFIED TAXPAYER IDENTI-
FICATION NUMBER.

  Other investor services are available. These include:
     
  . INVEST-A-CHECK (R) SERVICE enables a shareholder to authorize checks to
  be drawn on a regular checking account at regular monthly intervals     
 
                                       21

  in fixed amounts of $100 or more, or regular quarterly intervals in fixed
  amounts of $250 or more, to purchase Class A shares. (See "Terms and Condi-
  tions" on page 24.)     
     
  . AUTOMATIC DOLLAR-COST-AVERAGING SERVICE permits a shareholder to exchange
  a specified amount, at regular monthly intervals in fixed amounts of $100
  or more, or regular quarterly intervals in fixed amounts of $250 or more,
  from Class A shares of the Fund into Class A shares of any other Seligman
  Mutual Fund(s) registered in the same name. The shareholder's account must
  have a value of at least $5,000 at the initiation of the service. Exchanges
  will be made at the public offering price.     
         
  . DIVIDENDS FROM OTHER INVESTMENTS permits a shareholder to order dividends
  payable on shares of other companies to be paid to and invested in addi-

ADVERTISING THE FUND'S PERFORMANCE
   
  From time to time the Fund advertises its "total return" and "average annual
total return", each of which are calculated separately for Class A and Class D
shares. THESE FIGURES ARE BASED ON HISTORICAL EARNINGS AND ARE NOT INTENDED TO
INDICATE FUTURE PERFORMANCE. The "total return" shows what an investment in
shares of Class A or Class D of the Fund would have earned over a specified pe-
riod of time (for example, one, five and ten year periods or since inception)
assuming the payment of the maximum sales load, if any, when the investment was
made and that all distributions and dividends paid by the Fund were reinvested
on the reinvestment dates during the period. The "average annual total return"
is the annual rate required for the initial payment to grow to the amount which
would be received at the end of the specified period (one, five and ten year
periods or since inception); i.e., the average annual compound rate of return.
The total return and average annual total return of Class A shares quoted from
time to time through December 31, 1992 have not been adjusted to reflect the
deduction of the administration, shareholder services and distribution fee,
which if reflected would reduce the performance quoted. Total return and aver-
age annual total return may also be presented without the effect of the initial
sales load or CDSL, as applicable.     
   
  From time to time, reference may be made in advertising or promotional mate-
rial to performance information, including mutual fund rankings, prepared by
Lipper Analytical Service, Inc. ("Lipper"), an independent reporting service
which monitors the performance of mutual funds. In calculating the total return
of the Fund's Class A and Class D shares, the Lipper analysis assumes invest-
ment of all dividends and distributions paid but does not take into account ap-
plicable sales loads. The Fund may also refer in advertisements or in other
promotional material to articles, comments listings and columns in the finan-
cial press pertaining to the Fund's performance. Examples of such financial and
other press publications include Barron's, Business Week, CDA/Weisenberger Mu-
tual Funds Investment Report, Christian Science Monitor, Financial Planning,
Financial Times, Financial World, Forbes, Fortune, Individual Investor, Invest-
ment Advisor, Investors Business Daily, Kiplinger's, Los Angeles Times, MONEY
Magazine, Morningstar, Inc., Pensions and Investments, Smart Money, The New
York Times, USA Today, U.S. News and World Report, The Wall Street Journal,
Washington Post, Worth Magazine and Your Money.     
 
ORGANIZATION AND CAPITALIZATION
   
  The Fund is an open-end diversified management investment company incorpo-
rated under the laws of the state of Maryland in 1982. The Fund is authorized
to issue 100 million shares of common stock, each with a par value of $0.10,
divided into two classes. Each share of the Fund's Class A and Class D common
stock is equal as to earnings, assets and voting privileges, except that each
class bears its own separate distribution and 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 received
an order from the Securities and Exchange Commission 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 addi-
tional classes of common stock with such characteristics as are permitted by
the order received from the Securities and Exchange Commission. 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. Shares have non-cumulative voting rights, do not have preemptive or sub-
scription rights and are transferable.

                             TERMS AND CONDITIONS
 
                          GENERAL ACCOUNT INFORMATION
   
  Investments will be made in as many shares, including fractions to the third
decimal place, as can be purchased at the net asset value plus a sales load,
if applicable, at the close of business on the day payment is received. If a
check in payment of a purchase of Fund shares is dishonored for any reason,
Seligman Data Corp. will cancel the purchase and may redeem additional shares,
if any, held in a shareholder's account in an amount sufficient to reimburse
the Fund for any loss it may have incurred and charge a $10.00 return check
fee. Shareholders will receive dividends from investment income and any dis-
tributions from gain realized on investments in shares or in cash according to
the option elected. Dividend and gain options may be changed by notifying Se-
ligman Data Corp. in writing. These option changes must be received by Selig-
man Data Corp. on or before the record date for the dividend or distribution
in order to be effective for that dividend or distribution. Stock certificates
will not be issued, unless requested. Replacement Stock certificates will be
subject to a surety fee.     
 
                           INVEST-A-CHECK(R) SERVICE
   
  The Invest-A-Check(R) Service is available to all shareholders. The applica-
tion is subject to acceptance by the shareholder's bank and Seligman Data
Corp. Checks in the amount specified will be drawn automatically on the share-
holder's bank on the fifth day of each month (or on the prior business day if
the fifth day of the month falls on a weekend or holiday) in which an invest-
ment is scheduled and invested at the public offering price at the close of
business on the same date. After the initial investment, the value of shares
held in the shareholder's account must equal not less than two regularly
scheduled investments. If a check is not honored by the shareholder's bank, or
if the value of shares held falls below the required minimum, the Service will
be suspended. In the event that a check is returned marked "unpaid," Seligman
Data Corp. will cancel the purchase, redeem shares held in the shareholder's
account for an amount sufficient to reimburse the Fund for any loss it may
have incurred as a result, and charge a $10.00 return check fee. This fee may
be debited to the shareholder's account. The Service will be reinstated upon
written request indicating that the cause of interruption has been corrected.
The Service may be terminated by the shareholder or Seligman Data Corp. at any
time by written notice. The shareholder agrees to hold the Fund and its agents
free from all liability which may result from acts done in good faith and pur-
suant to these terms. Instructions for establishing Invest-A-Check(R) Service
are given on the Account Application. In the event a shareholder exchanges all
of the shares from one mutual fund in the Seligman Group to another, a share-
holder must re-apply for the Invest-A-Check(R) Service in the Seligman Fund
into which the exchange was made. In the event of a partial exchange, the In-
vest-A-Check(R) Service will be continued, subject to the above conditions, in
the Seligman Fund from which the exchange was made. If a shareholder uses the
Invest-A-Check(R) Service to make an IRA investment, the purchase will be
credited as a current year contribution. If a shareholder uses the Invest-A-
Check(R) Service to make an investment in a pension or profit sharing plan,
the purchase will be credited as a current year employer contribution.     
 
                       AUTOMATIC CASH WITHDRAWAL SERVICE
   
  Automatic Cash Withdrawal Service is available to Class A shareholders and
to Class D shareholders with respect to Class D shares held for one year or
more. A sufficient number of full and fractional shares will be redeemed to
provide the amount required for a scheduled payment. Redemptions will be made
at the asset value at the close of business on the specific day designated by
the shareholder of each month (or on the prior business day if the day speci-
fied falls on a weekend or holiday). A shareholder may change the amount of
scheduled payments or may suspend payments by written notice to Seligman Data
Corp. at least ten days prior to the effective date of such a change or sus-
pension. Service may be terminated by the shareholder or Seligman Data Corp.
at any time by written notice. It will be terminated upon proper notification
of the death or legal incapacity of the shareholder. This Service is consid-
ered terminated in the event a withdrawal of shares, other than to make sched-
uled withdrawal payments, reduces the value of shares remaining on deposit to
less than $5,000. Continued payments in excess of dividend income invested
will reduce and ultimately exhaust capital. Withdrawals, concurrent with pur-
chases of shares of this or any other investment company, will be disadvanta-
geous because of the payment of duplicative sales loads, if applicable. For
this reason, additional purchases of Fund shares are discouraged when the
Withdrawal Service is in effect.     
 
                     LETTER OF INTENT--CLASS A SHARES ONLY
   
  Seligman Financial Services, Inc. will hold in escrow shares equal to 5% of
the minimum purchase amount specified. Dividends and distributions on the
escrowed shares will be paid to the shareholder or credited to their account.
Upon completion of the specified minimum purchase within the thirteen-month
period, all shares held in escrow will be deposited to the shareholder's ac-
count or delivered to the shareholder. A shareholder may include the total as-
set value of shares of the mutual funds in the Seligman Group on which a sales
load was paid owned as of the date of a Letter of Intent toward the completion
of the Letter. If the total amount invested within the thirteen-month period
does not equal or exceed the specified minimum purchase, a shareholder will be
requested to pay the difference between the amount of the sales load paid and
the amount of the sales load applicable to the total purchase made. If, within
20 days following the mailing of a written request, a shareholder has not paid
this additional sales load to Seligman Financial Services, sufficient escrowed
shares will be redeemed for payment of the additional sales load. Shares re-
maining in escrow after this payment will be released to the account. The in-
tended purchase amount may be increased at any time during the thirteen-month
period by filing a revised Agreement for the same period, provided that the
Dealer furnishes evidence that an amount representing the reduction in sales
load under the new Agreement, which becomes applicable on purchases already
made under the original Agreement, will be refunded to the shareholder and
that the required additional escrowed shares are being furnished by the share-
holder.     
 
  Shares of Seligman Cash Management Fund which have been acquired by an ex-
change of shares of another mutual fund in the Seligman Group on which there
is a sales load may be taken into account in completing a Letter of Intent, or
for Rights of Accumulation. However, shares of this Fund which have been pur-
chased directly may not be used for purposes of determining reduced sales
loads on additional purchases of the other mutual funds in the Seligman Group.
                                                                    
                                                                 Rev. 5/95

                     of  each  such  Fund,  as  amended  from  time to  time.  I
                     understand that redemptions of uncertificated  shares of up
                     to  $50,000  will be sent  only to my  account  address  of

                     information  to  verify a  caller's  identity  and  sending
                     written confirmations of transactions.  As a result of this
                     policy, I may bear the risk of any loss due to unauthorized
                     or fraudulent telephone  instructions;  provided,  however,
                     that if the Fund(s) or SDC fail to employ such  procedures,
                     the Fund(s)  and/or SDC may be liable.  TO ELECT  TELEPHONE

purchased at net asset value plus a sales load of up to 4.75%.  Class D shares
may be purchased at net asset value and are subject to a contingent deferred
sales load ("CDSL") of 1% if redeemed within one year.

          Each Class A and Class D share represents an identical legal interest
in the investment portfolio of the Fund and has the same rights except for
certain class expenses and except that Class D shares bear a higher distribution
fee that generally will cause the Class D shares to have a higher expense ratio
and pay lower dividends than Class A shares.  Each Class has exclusive voting
rights with respect to its distribution plan.  Although holders of Class A and
Class D shares have identical legal rights, the different expenses borne by each
Class will result in different net asset values and dividends.  The two classes
also have different exchange privileges.

                   INVESTMENT OBJECTIVES, POLICIES AND RISKS

 As stated in the Prospectus, the Fund seeks to produce capital gain by
investing in a portfolio consisting of securities of domestic and foreign
companies operating in virtually all aspects of the communications, information
and related industries.

 Illustrative subsegments of these industries include:

                               .  Advertising
                       .  Broadcasting and Entertainment
                               .  Cellular Radio
                  .  Computer-Aided Design and Manufacturing
                       .  Computer Graphics and Software
      .  Local Networking and Linkage of Word and Data Processing Systems
                             .  Medical Technology
                           .  Proprietary Databases
                         .  Publishing and Print Media
                               .  Semiconductors
                      .  Specialized Information Services

    The Fund may hold securities of smaller, less-seasoned companies. The
disposition of some of the securities held by the Fund may be restricted under
the federal securities laws. Generally, such "restricted securities" may be sold
only in privately negotiated transactions or in public offerings registered
under the Securities Act of 1933. As a result, the Fund may not be able to
dispose of such investments at a time when or at a price at which it desires to
do so and may have to bear expenses of registering these securities, if
necessary. Market value for these securities, if quotations are not readily
available, will be fair value as determined in good faith by the Board of
Directors. The Fund will not invest more than 10% of its net assets in illiquid
securities including restricted securities.

Borrowing.  The Fund may from time to time borrow money from banks to increase
- ---------                                                                     
its portfolio of securities.

    Borrowings are subject to any applicable limitations under regulations of
the Federal Reserve Board. Current asset value coverage of three times any
amount borrowed is required at all times. No borrowing occurred in 1994, 1993
and 1992.

    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.

Lending of Portfolio Securities.  The Fund may lend portfolio securities to
- -------------------------------                                            
certain institutional borrowers of securities and may invest the cash collateral
and obtain additional income or receive an agreed upon amount of interest from
the borrower.  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 cash or equivalent 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.
    
Rights and Warrants.  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.    

Repurchase Agreements.  The Fund may enter into repurchase agreements with
- ---------------------                                                     
commercial banks and with broker/dealers to invest cash for the short-term.  A
repurchase agreement is an agreement under which the Fund acquires a money
market instrument, generally a U.S. Government obligation subject to resale at
an agreed upon price and date.  Such resale price reflects an agreed upon
interest rate effective for the period of time the instrument is held by the
Fund and is unrelated to the interest rate on the instrument.  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, decline in value of the underlying
securities and loss of interest.  Repurchase agreements usually are for short
periods, such as one 

                                      -2-
<PAGE>
 
week or less, but may be for longer periods. However, 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. The
Fund has no present intention of entering into repurchase agreements in the
future.

    Except as described under "Investment Limitations" below, the foregoing
investment policies are not fundamental and the Board of Directors of the Fund
may change such policies without the vote of a majority of its outstanding
voting securities (as defined on page 4).
    
Portfolio Turnover.  The Fund's portfolio turnover rate is calculated by
- ------------------                                                      
dividing the lesser of purchases or sales of portfolio securities for the fiscal
year by the monthly average value of the portfolio securities owned during the
fiscal year.  Securities whose maturity or expiration date at the time of
acquisition were one year or less are excluded.  The Fund's portfolio turnover
rate was 104.08% in 1994 and 137.10% in 1993.     

                            INVESTMENT LIMITATIONS

    Under the Fund's fundamental policies, which cannot be changed except by
vote of a majority of its outstanding voting securities, 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 secure permitted borrowings up to 10% of
   the value of its total assets (taken at cost);

.  Purchase securities on "margin," or sell "short", or participate on a joint
   or a joint and several basis in any securities trading account, or write or
   purchase put, call, straddle or spread options;

.  Invest more than 5% of its total assets (taken at market) in securities of
   any one issuer other than the U.S. 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;

.  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.
    
   Although not fundamental policies subject to shareholder vote, as long as the
Fund's shares are registered in certain states, it may not (1) mortgage, pledge
or hypothecate its assets to the extent that the value of such encumbered assets
exceed 10% of the per share offering price of shares of the Fund; (2) invest in
interests in oil, gas or other mineral exploration or development programs; and
(3) invest more than 5% of its gross assets at market value in combined
investments in securities of companies in operation for less than three years
(excluding securities guaranteed by a company which, including predecessors, has
been in operation at least three continuous years). Also, in accordance with
Texas securities regulations, purchase or sell real property or limited
partnership interests in real property (but excluding readily marketable
interests in real estate investment trusts or readily marketable securities of
companies which invest in real estate).     

  Under the Investment Company Act of 1940 (the "1940 Act"), a "vote of a
majority of the outstanding voting securities" 

                                      -3-
<PAGE>
 
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.

(1)  Based on remuneration received by the Directors of the Fund for the year
ended December 31, 1994.     
    
(2)  As defined in the Fund's Prospectus, the Seligman Group of Investment
Companies consists of seventeen investment companies.     
    
(d)  Deferred.  The total amounts of deferred compensation (including interest)
payable to Messrs. Merow, Pitney and Whitson as of December 31, 1994 were
$35,953, $34,077 and $3,998, respectively.  Mr. Pitney no longer defers current
compensation.     
    
   The Fund has a compensation arrangement under which outside directors may
elect to defer receiving their fees. Under this arrangement, interest is accrued
on the deferred balances. The annual cost of such interest is included in the
directors' fees and expenses, and the accumulated balance thereof is included in
"Liabilities" in the Fund's financial statements.     
    
   Directors and officers of the Fund are also directors or trustees and
officers of some or all of the other investment companies in the Seligman Group.
Directors and officers of the Fund as a group owned directly or indirectly
80,496 shares or less than 1% of the Fund's Class A Capital Stock at March 31,
1995. As of that date, no Directors or officers owned shares of the Fund's Class
D Capital Stock.     

                            MANAGEMENT AND EXPENSES

   As indicated in the Prospectus, under the Management Agreement, dated
December 29, 1988, subject to the control of the Board of Directors, the Manager
manages the investment of the assets of the Fund, including making purchases and
sales of portfolio securities consistent with the Fund's investment objectives
and policies, and administers its business and other affairs. The Manager
provides the Fund with such office space, administrative and other services and
executive and other personnel as are necessary for Fund operations. The Manager
pays all of the compensation of directors of the Fund who are employees or
consultants of the Manager and of the officers and employees of the Fund. The
Manager also provides senior management for Seligman Data Corp., the Fund's
shareholder service agent.
    
   The Fund pays the Manager a management fee for its services, calculated daily
and payable monthly, equal to 0.75% of the daily net assets of the Fund.  The
management fees paid for 1994, 1993 and 1992 were $1,547,256, $529,841 and
$378,816 respectively, or .75%, .75% and .75%, respectively, of the Fund's
average net assets.     

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

                                      -7-
<PAGE>
 
    
securities laws, expenses of shareholders' meetings, expenses of corporate data
processing and related services, shareholder record keeping and shareholder
account services, fees and disbursements of transfer agents and custodians,
expenses of disbursing dividends and distributions, fees and expenses of
directors of the Fund not employed by (or serve as a Director of) the Manager or
its affiliates, insurance premiums and extraordinary expenses such as litigation
expenses.  The Manager has undertaken to one state securities administrator, so
long as required, to reimburse the Fund for each year in the amount by which
total expenses, including the management fee, but excluding interest, taxes,
brokerage commissions, distribution fees, extraordinary expenses and a portion
of expenses related to shareholder account and transfer services, exceed 2 1/2%
of the first $30,000,000 of average net assets, 2% of the next $70,000,000 and 1
1/2% thereafter.  Such reimbursement, if any, will be made monthly.     

   On December 29, 1988, a majority of the outstanding voting securities of the
Manager was purchased by Mr. William C. Morris and a simultaneous
recapitalization of the Manager occurred.

   The Management Agreement was approved by the Board of Directors on September
30, 1988 and by the shareholders at a Special Meeting held on December 16, 1988.
The Management Agreement will continue in effect until December 31 of each year
if (1) such continuance is approved in the manner required by 1940 Act (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) if the Manager 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 the Manager 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 the Manager's business.

   The Manager is a successor firm to an investment banking business founded in
1864 which has thereafter provided investment services to individuals, families,
institutions and corporations.  See the Appendix for further history of the
Manager.
    
   Under the Subadvisory Agreement, dated June 1, 1994, the Subadviser
supervises and directs a portion of the Fund's investment in foreign securities
and Depository Receipts consistent with the Fund's investment objectives,
policies and principles. For these services, the Subadviser is paid a fee as
described in the Fund's Prospectus. The Subadvisory Agreement was approved by
the Board of Directors at a meeting held on January 20, 1994 and by the
shareholders of the Fund on May 19, 1994. The Subadvisory Agreement will
continue in effect until December 31, 1995, and from year to year thereafter if
such continuance is approved in the manner required by the 1940 Act (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 Subadvisory Agreement or interested persons of any such party) and (2) if
the Subadviser shall not have notified the Manager in writing at least 60 days
prior to December 31 of any year that it does not desire such continuance. The
Subadvisory Agreement may be terminated at any time by the Fund, on 60 days
written notice to the Subadviser. The Subadvisory Agreement will terminate
automatically in the event of its assignment or upon the termination of the
Management Agreement.    
    
   For the period June 1, 1994 through December 31, 1994, the Fund did not
require the services of the Subadviser.     
    
   The Subadviser is a New York general partnership formed by the Manager and
Henderson International, Inc., a controlled affiliate of Henderson
Administration Group plc.  Henderson Administration Group plc, headquartered in
London, is one of the largest independent money managers in Europe.  The Firm
currently  manages approximately $18.5 billion in assets and is recognized as a
specialist in global equity investing.     
    
   Officers, directors and employees of the Manager are permitted to engage in
personal securities transactions, subject to the Manager's Code of Ethics (the
"Code").  The Code proscribes certain practices with regard to personal
securities transactions and personal dealings, provides a framework for the
reporting and monitoring of personal securities transactions by the Manager's
Director of Compliance, and sets forth a procedure of identifying, for
disciplinary action, those individuals who violate the Code.  The Code prohibits
each of the officers, directors and employees (including all portfolio managers)
of the Manager from purchasing or selling any security that the officer,
director or employee knows or believes (i) was recommended by the Manager for
purchase or sale by any client, including the Fund, within the preceding two
weeks, (ii) has been reviewed by the Manager for possible purchase or sale
within the preceding two weeks, (iii) is being purchased or sold by any client,
(iv) is being considered by a research analyst, (v) is being acquired in a
private placement, unless prior approval has been obtained from the Manager's
Director of Compliance, or (vi) is being acquired during an initial or     

                                      -8-
<PAGE>
 
    
secondary public offering.  The Code 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 also prohibits (i) 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
(ii) 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 the
Manager'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.     

          ADMINISTRATION, SHAREHOLDER SERVICES AND DISTRIBUTION PLAN

   As indicated in the Prospectus, the Fund has adopted an Administration,
Shareholder Services and Distribution Plan for each Class (the "Plan") in
accordance with Section 12(b) of the Act and Rule 12b-1 thereunder.
    
   The Plan was approved on July 16, 1992 by the Board of Directors of the Fund,
including a majority of the Directors who are not "interested persons" (as
defined in the Act) and who have no direct or indirect financial interest in the
operation of the Plan or in any agreement related to the Plan (the "Qualified
Directors") and was approved by shareholders of the Fund at a Special Meeting of
Shareholders held on November 23, 1992.  The Plan became effective in respect of
the Class A shares on January 1, 1993.  The Plan was approved in respect of the
Class D shares on March 18, 1993 by the Board of Directors of the Fund,
including a majority of the Qualified Directors, and became effective with
respect to the Class D shares on May 1, 1993.  The Plan will continue in effect
through December 31 of each year so long as such continuance is approved by a
majority vote of both the Directors and the Qualified Directors of the Fund,
cast in person at a meeting called for the purpose of voting on such approval.
The 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 and no material amendment to
the Plan may be made except by a majority of both the Directors and Qualified
Directors.     

   The 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 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.

                            PORTFOLIO TRANSACTIONS
    
   The Management and Subadvisory Agreements recognize that in the purchase and
sale of portfolio securities the Manager and Subadviser will seek the most
favorable price and execution, and, consistent with that policy, may give
consideration to the research, statistical and other services furnished by
brokers or dealers to the Manager and Subadviser for their use, as well as to
the general attitude toward and support of investment companies demonstrated by
such brokers or dealers.  Such services include supplemental investment
research, analysis and reports concerning issuers, industries and securities
deemed by the Manager and Subadviser to be beneficial to the Fund.  In addition,
the Manager and Subadviser are authorized to place orders with brokers who
provide supplemental investment and market research and statistical 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 the Manager and Subadviser in connection with its
services to clients other than the Fund.     
    
   In over-the-counter markets, the Fund deals with 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.     
    
   When two or more of the investment companies in the Seligman Group or other
investment advisory clients of the Manager and Subadviser desire to buy or sell
the same security at the same time the securities purchased or sold are
allocated by the Manager and Subadviser 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.

Notes:

(2) Brokerage commissions paid to Seligman Securities, Inc. were 4.1% and 50.8%
    of total brokerage commissions paid for 1993 and 1992 respectively. The
    aggregate dollar amount of the Fund's transactions for which Seligman
    Securities, Inc. acted as broker was 5.4% of the total dollar amount of all
    commission transactions in 1993 and 51.1% in 1992. The Board of Directors
    adopted procedures effective January 1, 1984, pursuant to which Seligman
    Securities, Inc. was available to the Fund as broker for approximately one-
    half of agency transactions in listed securities at commission rates
    believed in accordance with applicable regulations to be fair and
    reasonable. As of March 31, 1993, Seligman Securities, Inc. ceased
    functioning as a broker for the Fund and its other clients.

   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 Funds in
the Seligman Group which are sold with a sales load, reaches levels indicated in
the sales load schedule set forth in the Prospectus.     
    
   THE RIGHT OF ACCUMULATION allows an investor to combine the amount being
invested Class A in shares of the Fund and shares of Seligman Capital Fund,
Seligman Common Stock Fund, Seligman Frontier Fund, Seligman Growth Fund,
Seligman Henderson Global Fund Series, Seligman High Income Fund Series,
Seligman Income Fund, Seligman New Jersey Tax-Exempt Fund, Seligman Pennsylvania
Tax-Exempt Fund Series, Seligman Tax-Exempt Fund Series, or Seligman Tax-Exempt
Series Trust sold with a sales load with the total net asset value of shares of
those Mutual Funds already owned that were sold with a sales load and the total
net asset value of shares of Seligman Cash Management Fund which were acquired
through an exchange of shares of another Mutual Fund in the Seligman Group on
which there was a sales load at the time of purchase to determine reduced sales
loads in accordance with the schedule in the Prospectus. The value of the shares
owned, including the value of shares of Seligman Cash Management Fund acquired
in an exchange of shares of another Mutual Fund in the Seligman Group on which
there was a sales load at the time of purchase, will be taken into account in
orders placed through a dealer, however, only if Seligman Financial Services,
Inc. is notified by an investor or a dealer of the amount owned 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 sales loads 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 sold with a sales load of Seligman Capital Fund, Seligman Common Stock
Fund, Seligman Frontier Fund, Seligman Growth Fund, Seligman Henderson Global
Fund Series, Seligman High Income Fund Series, Seligman Income Fund, Seligman
New Jersey Tax-Exempt Fund, Seligman Pennsylvania Tax-Exempt Fund Series,
Seligman Tax-Exempt Fund Series, or Seligman Tax-Exempt Series Trust 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 Mutual Fund in the
Seligman Group on which there was a sales load at the time of purchase.  Reduced
sales loads 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.  For more
information concerning the terms of the letter of intent see "Terms and
Conditions-Letter of Intent-Class A Shares Only" accompanying the Account
Application in the Prospectus.     
    
Persons Entitled To Reductions.  Reductions in sales loads 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, tax-exempt
organizations under Section 501 (c)(3) or (13), 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 term "eligible employee benefit plan"
- -------------------------------                                            
means any plan or arrangement, whether or not tax qualified, which provides for
the purchase of Fund shares.  The term "participant account plan" means any
"eligible employee benefit plan" where (i) the Fund shares are purchased through
payroll deductions or otherwise by a fiduciary or other person for the account
of participants who are employees (or their spouses) of an employer and (ii) a
separate Open Account is maintained in the name of such fiduciary or other
person for the account of each participant in the plan (such as a payroll
deduction IRA program).     
    
   The table of sales loads 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," of employers who have at least 2,000
U.S. employees to whom such plan is made available  or, regardless of the number
of employees, if such plan is established or maintained by any dealer which has
a sales agreement with Seligman Financial Services, Inc.  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 ser-     

                                      -11-
<PAGE>
 
vice agent. 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 investment dealers or
Seligman Financial Services, Inc.

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 plus any applicable sales load) 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 the Manager 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 loads, 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.  Any securities in the
manner provided for valuing portfolio securities of the Fund.  Any securities
accepted by the Fund in payment for Fund shares will have an active and
substantial market and have a value which is readily ascertainable (See
"Valuation").  In accordance with Texas securities regulations, should the Fund
accept securities in payment for shares, such transactions would be limited to a
bona fide reorganization, statutory merger, or to other acquisitions of
portfolio securities (except for municipal debt securities issued by state
political subdivisions or their agencies or instrumentalities) which meet the
investment objectives and policies of the investment company; are acquired for
investment and not for resale; are liquid securities which are not restricted as
to transfer either by law or liquidity of market; and have a value which is
readily ascertainable (and not established only by evaluation procedures) as
evidenced by a listing on the American Stock Exchange, the New York Stock
Exchange or NASDAQ.
    
Further Types of Reductions.  Class A shares may be issued without a sales load
- ---------------------------                                                    
in connection with the acquisition of cash and securities owned by other
investment companies and personal holding companies, to financial institution
trust departments, to registered investment advisers exercising discretionary
investment authority with respect to the purchase of Fund shares, or pursuant to
sponsored arrangements with organizations which make recommendations to, or
permit group solicitation of, its employees, members or participants in
connection with the purchase of shares of the Fund, and to separate accounts
established and maintained by an insurance company which are exempt from
registration under Section 3(c)(11) of the Investment Company Act of 1940, to
registered representatives (and their spouses and minor children) and employees
of any dealer that has a sales agreement with SFSI, to shareholders of mutual
funds with investment objectives and policies similar to the Fund's who purchase
shares with redemption proceeds of such funds and to certain unit investment
trusts as described in the Prospectus.     

   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.

More About Redemptions.  The procedures for redemption of Fund shares under
- ----------------------                                                     
ordinary circumstances are set forth in the Prospectus.  In unusual
circumstances payment may be postponed, if the orderly liquidation of portfolio
securities is prevented by the closing of, or restricted trading on the New York
Stock Exchange during periods of emergency, or such other periods as ordered by
the Securities and Exchange Commission.   Payment may be made in securities,
subject to the review of some state securities commissions.  If payment is made
in securities, a shareholder may incur brokerage expenses in converting these
securities into cash.

                             DISTRIBUTION SERVICES
    
   The Fund and Seligman Financial Services, Inc. ("SFSI") are parties to a
Distributing Agreement, dated January 1, 1993.  SFSI, an affiliate of the
Manager, acts as general distributor of the shares of the Fund and of the other
mutual funds in the Seligman Group.  As general distributor of the Fund's
Capital Stock, SFSI allows concessions to all dealers, as indicated in the
Prospectus.  Pursuant to agreements with the Fund, certain dealers may also
provide sub-accounting and other services for a fee.  SFSI receives the balance
of sales loads and any CDSLs paid by investors.  The balance of sales loads paid
by investors and received by SFSI in respect of Class A shares amounted to
$693,835 in 1994, after allowance of $5,926,699 as concessions to dealers;
$48,139 in 1993, after allowance of $773,862 as concessions to dealers; and
$8,320 in 1992, after allowance of $70,934 as concessions to dealers.  For the
year ended December 31, 1994, SFSI retained CDSL charges from Class D shares
amounting to $34,431; and $1,420 for the period May 3, 1993 to December 31,
1993.     

                                      -12-
<PAGE>
 
   Class A shares may be sold at net asset value to present and retired
directors, trustees, officers, employees (and their spouses and minor children)
of the Fund, the other investment companies in the Seligman Group, the Manager
and other companies affiliated with the Manager. Such sales also may be made to
employee benefit and thrift plans for such persons and to any investment
advisory, custodial, trust or other fiduciary account managed or advised by the
Manager or any affiliate. These sales may be made for investment purposes only,
and shares may be resold only to the Fund.

                                   VALUATION
    
   Net asset value per Fund share is determined as of the close of trading on
the New York Stock Exchange, (usually 4:00 p.m. Eastern time), each day that the
New York Stock Exchange is open. The New York Stock Exchange is currently closed
on New Year's Day, Presidents' Day, Good Friday, Memorial Day, Independence Day,
Labor Day, Thanksgiving Day and Christmas Day. The fair value of any restricted
securities held by the Fund will be determined by the Manager in accordance with
procedures approved by the Directors. This value generally will be determined as
the amount which the Fund could reasonably expect to receive from an orderly
disposition of these securities over a reasonable period of time. The net asset
value of Class D shares will generally be lower than the net asset value of
Class A shares as a result of the larger distribution fee with respect to Class
D shares.     
    
   The net asset value per share is determined separately for each class of
shares.  Portfolio securities, including open short positions and options
written, are valued at the last sale price on the securities exchange or
securities market on which such securities primarily are traded.  Securities
traded on a foreign exchange or over-the-counter market are valued at the last
sales price on the primary exchange or market on which they are traded.  United
Kingdom securities for which there are not recent sales transactions are valued
based on quotations provided by primary market makers in such securities.  Any
securities for which recent market quotations are not readily available,
including restricted securities, are valued at fair value as determined in
accordance with procedures approved by the Board of Directors.  Short-term
obligations with less than sixty days remaining to maturity are generally valued
at amortized cost.  Short-term obligations with more than sixty days remaining
to maturity will be valued at current market value until the sixtieth day prior
to maturity, and will then be valued on an amortized cost basis based on the
value on such date unless the Board determines that this amortized cost value
does not represent fair market value.  Expenses and fees, including the
investment management fee, are accrued daily and taken into account for the
purpose of determining the net asset value of Fund shares.     

   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. Occasionally, events
affecting the value of such securities and such exchange rates may occur between
the times at which they are determined and the close of the NYSE, which will not
be reflected in the computation of net asset value. If during such periods
events occur which materially affect the value of such securities, the
securities will be valued at their fair market value as determined in accordance
with procedures approved by the Board of Directors.

   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.

                                  PERFORMANCE
    
   The Fund's average annual total returns of Class A shares for the one-year,
five-year and ten-year periods ended December 31, 1994 were 28.87%, 23.00% and
21.61% respectively.  These amounts were computed by assuming a hypothetical
initial payment of $1,000, subtracting the maximum sales load of $47.50 (4.75%
of public offering price) and assuming that all of the dividends and
distributions by the Fund over the relevant time period were reinvested.  It was
then assumed that at the end of these periods the entire amount was redeemed.
The average annual total returns were then calculated by calculating the annual
rate required for the initial payment to grow to the amount which would have
been received upon redemption (i.e., the average annual compound rate of
return).  The average annual total returns for Class D shares of the Fund for
the one-year period ended December 31, 1994 and since inception through December
31, 1994 were 32.94% and 42.72%, respectively.  This amount was computed
assuming a hypothetical initial payment of $1,000 and that all of the dividends
and distributions paid by the Fund's Class D shares, if any, were reinvested
over the relevant time period.  For the one-year period ended December 31, 1994,
it was then assumed that at the end of the period, the entire amount was
redeemed, subtracting the applicable 1% CDSL.     

                                      -13-
<PAGE>
 
    
   Table A below illustrates the total return (income and capital) on Class A
shares of the Fund with dividends invested and gain distributions, if any, taken
in shares.  It shows that a $1,000 investment in Class A shares, assuming
payment of the 4.75% sales load, made on January 1, 1985 had a value of $7,073
on December 31, 1994, resulting in an aggregate total return of 607.31%.  Table
B illustrates the total return (income and capital) on Class D shares of the
Fund with dividends invested and gain distributions, if any, taken in shares.
It shows that a $1,000 investment in Class D shares made on May 3, 1993
(commencement of offering of Class D shares) had a value of $1,807 on December
31, 1994 resulting in an aggregate total return of 80.67%.  The results shown
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.

     offering of Class D shares on May 3, 1993.     

(2)  The "Value of Initial Investment" as of the date indicated reflects the
     effect of the maximum sales load, assumes that all dividends and capital
     gains distributions were taken in cash and reflect changes in the net asset
     value of the shares purchased with they hypothetical initial investment.
     "Total Value" reflects the effect of the CDSL, if applicable, assumes
     investment of all dividends and capital gain distributions and reflects
     changes in the net asset value.

(3)  "Total Return" for each class of shares of the Fund is calculated by
     assuming a hypothetical initial investment of $1,000 at the beginning of
     the period specified, subtracting the maximum sales load for Class A
     shares; determining total value of all dividends and distributions that
     would have been paid during the period on such shares assuming that each
     dividend or distribution was invested in additional shares at net asset
     value; calculating the total value of the investment at the end of the
     period, subtracting the CDSL on Class D shares, if applicable; and finally,
     by dividing the difference between the amount of the hypothetical initial
     investment at the beginning of the period and its total value at the end of
     the period by the amount of the hypothetical initial investment.

No adjustments have been made for any income taxes payable by investors on
dividends invested or gain distributions taken in shares.

    The total return and average annual total return of the Class A shares
quoted from time to time through December 31, 1992 does not reflect the
deduction of the administration, shareholder services and distribution fee,
effective January 1, 1993, which fee is reflected would reduce the performance
quoted.

    The Fund may also include its aggregate total return over a specified period
in advertisements or in information furnished to present or prospective
shareholders.

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

    
    Seligman's beginnings date back to 1837, when Joseph Seligman, the oldest of
eight brothers, arrived in the United States from Germany.  He earned his living
as a pack peddler in Pennsylvania, and began sending for his brothers.  The
Seligmans became successful merchants, establishing businesses in the South and
East.     
    
    Backed by nearly thirty years of business success - culminating in the sale
of government securities to help finance the Civil War - Joseph Seligman, with
his brothers, established the international banking and investment firm of J. &
W. Seligman & Co. In the years that followed, Seligman played a major role in
the geographical expansion and industrial development of the United States.

To the Shareholders
- --------------------------------------------------------------------------------
 
  We are pleased to report Seligman Communications and Information Fund's long-
term investment results, portfolio holdings, and audited financial statements at
December 31, 1994.

  It is our pleasure to report that at December 31, your Fund was ranked the
number one Fund of all equity mutual funds measured by Lipper Analytical
Services for both the one- and five-year periods ended December 31, 1994, of the
2,018 and 878 funds measured, respectively. Your Fund is number two for the 10-
year period, of the 445 equity mutual funds measured. Lipper's rankings are
based on total return and do not include sales charges.

  For your Fund's Class A shares, net asset value per share was $16.64 at
December 31, compared to $16.79 at September 30, and $13.43 a year ago. For your
Fund's Class D shares, net asset value per share was $16.31 at December 31,
compared to $16.53 at September 30, and $13.32 a year ago. For both Class A and
D shares, net realized gain per share from investment transactions in 1994 was
$1.46.

  For your Fund's Class A shares, total return was an outstanding 8.22% for the
three months and 35.30% for the 12 months ended December 31. For your Fund's
Class D shares, total return was 7.93% and 33.94%, respectively, for the same
periods. This compares to the Standard & Poor's 500 Composite Stock Price
Index's total return of -0.02% for the three months and 1.32% for the 12 months
ended December 31. (Total return reflects change in net asset value and assumes
any distributions paid within the period are reinvested in additional shares.
Class A returns do not, however, reflect the effect of the maximum initial sales
charge of 4.75%, and Class D returns do not reflect the effect of the 1%
contingent deferred sales load.)

  Looking back on 1994, the one generalization that can be made with confidence
is that it was a turbulent and trying year for equity and bond investors alike.
The Federal Reserve Board exhibited an aggressive stance against inflation,
putting through six short-term interest rate increases by the end of the year.
This caused an upheaval in the bond market, with yields increasing and bond
prices spiraling lower--an event in the financial markets unmatched in magnitude
since 1973-74. The equity market remained hostage to the bond market and
demonstrated lackluster performance for the year.

  The U.S. economy continued to grow at a modest yet controlled pace,
accompanied by corporate news of solid growth and strong earnings. This economic
news, although positive, caused the underlying question to remain: Will the
economy overheat, opening the door to increased inflation? We don't believe so.

  We believe an economic slowdown is close at hand. In March of 1995, the
current growth cycle will mark its fourth year. The consumer has both increased
debt as a percentage of income and drawn down savings--suggesting nearer-term
caution after a stronger-than-expected pattern of spending in 1994. We also
believe that inflation will remain under control in light of intense global
competition, low unit labor costs, and an aging population that should favor
saving over spending. Job creation remains robust despite gains in productivity,
and U.S. competitiveness in world markets is likely to be enhanced under
G.A.T.T.--General Agreement on Tariffs and Trade.

Federal Tax Status of
1994 Gain Distribution
For Taxable Accounts
 
The distribution of $1.46 per share, consisting of $0.39 from net long-term gain
and $1.07 from net short-term gain, realized on investment transactions during
1994, was paid on December 20, 1994, to both Class A and D shareholders.
 
  The long-term gain distribution is designated a "capital gain dividend" for
federal income tax purposes and is taxable to shareholders in 1994 as a long-
term gain from the sale of capital assets, no matter how long you may have owned
your shares 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 from
date of purchase, any loss would be treated as long-term to the extent that it
offsets the long-term gain distribution. The net short-term gain is taxable as
ordinary income whether paid to you in shares or in cash.

  If the distribution was received in shares, the per share cost basis for
federal income tax purposes is $15.87 for Class A and $15.56 for Class D. The
tax cost basis of shares previously held is not affected.

  A year-end statement of account showing activity for 1994 has been mailed to
each shareholder. Under "Tax Information for Calendar Year," it shows the
proceeds of any redemptions paid to the shareholder during the year and reported
to the Internal Revenue Service as required by federal regulations (Form 1099-
B). In addition, a separate Form 1099-DIV showing the amount of the distribution
from gain on investments paid during the year has been mailed to each
shareholder.

Annual Performance Overview
- --------------------------------------------------------------------------------
 
The following is a biography of your Portfolio Manager, a discussion with him
regarding Seligman Communications and Information Fund, and a comparison chart
of your Fund's performance against the Standard & Poor's 500 Composite Stock
Price Index and the Lipper Science and Technology Fund Average.
 
Your Portfolio Manager

[photograph]

Paul H. Wick is a Managing Director and Vice President of J. & W. Seligman & Co.
Incorporated and the Portfolio Manager of Seligman Communications and
Information Fund. Mr. Wick joined Seligman in 1987 as an Associate, Investment
Research, and from April 1989 to December 1989 was Co-Portfolio Manager of
Seligman High-Yield Bond Series. He has been Portfolio Manager of Seligman
Frontier Fund since August 1991, and Seligman Communications and Information
Fund since December 1989.
 
Economic Factors Affecting Seligman Communications and Information Fund
 
"In 1994, technology stocks as a group benefited from the strong global demand
for the key technology `end markets:' personal computers; networking;
telecommunications equipment; software; and wireless communications. In turn,
the strength of these markets created a healthy climate for their suppliers:
contract manufacturers; semiconductor companies; and suppliers of capital
equipment to the electronics market. In general, every industry involved in the
technology `end markets' thrived, from the providers of parts and manufacturers
of equipment, to the suppliers of the final product."
 
Your Manager's Investment Strategy
 
"As in 1993, your Fund's emphasis this past year on investing in fast-growing
companies that demonstrate the potential for positive earnings surprises proved
quite rewarding. We believe that the secular bull market for technology
experienced thus far in the 1990s will continue through this decade. The
industry is benefiting from both the capital investment cycle that is driving
the current economic expansion, and the information-driven revolution that has
been unfolding. Technology continues to dominate the office, the factory, the
home, and the transportation and entertainment industries; as a result it will
continue to capture a greater share of corporate and consumer spending over
time.
 
"While in the past your Fund's holdings included those industries that benefit
from technology, such as media, broadcasting, and entertainment, in recent years
we have focused heavily on the industries that create and supply communications
and technology products, as they continue to show the greatest growth
potential."
 
Individual Sector Performance
 
"The notable outperformance of your Fund was due largely to successful
investments made in the semiconductor and semiconductor capital equipment
industries. These areas did particularly well through the first nine months of
the year before fading somewhat in the fourth quarter. Fortunately, in September
and October, we locked in profits by selling several richly valued semiconductor
capital equipment holdings, including Ultratech Stepper. We also took profits in
some of our big winners in the networking industry, such as Alantec; however,
the networking group as a whole continued to appreciate in value as the year
progressed. In addition, due to the healthy demand for technology products, the
contract manufacturing sector also performed strongly, as these companies
assemble the sub-systems necessary for finished technology products."


Looking Ahead

"We believe 1995 will be an advantageous environment for technology issues. More
specifically, the overall technology industry, and your Fund in particular,
should benefit from the increased spending associated with two key events: the
emergence of the Intel Pentium chip in the mainstream of the PC market, and the
launch of Microsoft's new operating system for PCs-- Windows95. Because these
advances in the computer market will continually demand upgraded products and
services, every industry involved in the process of manufacturing PCs should
benefit, which bodes well for your Fund's investments."

No adjustment was made to performance for periods prior to January 1, 1993, the
commencement date for the annual Administration, Shareholder Services and
Distribution Plan fee of up to 0.25% of average daily net assets of Class A
shares. The performance of Class 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. Performance data quoted represent changes in
prices and assume that all distributions within the periods are invested in
additional shares. The investment return and principal value of an investment
will fluctuate so that shares, if redeemed, may be worth more or less than their
original cost. Past performance is not indicative of future investment results.

Notes to Financial Statements
- ------------------------------------------------------------------------
 
1. Effective May 3, 1993, Seligman Communications and Information Fund, Inc.
(the "Fund") began offering two classes of shares. All shares existing prior to
May 3, 1993, have been classified as Class A 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 D shares are sold without an initial sales
charge but are subject to a higher distribution fee and a contingent deferred
sales load ("CDSL") of 1% imposed on certain redemptions made within one year of
purchase. The two 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 class
expenses and has exclusive voting rights with respect to any matter to which a
separate vote of any class is required.

2. Significant accounting policies followed, all in conformity with generally
accepted accounting principles, are given below:
   a. Investments in common stocks are valued at current market values or, in
      their absence, at fair value 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, a mean of bid and asked prices. 
      Short-term holdings maturing in 60 days or less are valued at amortized 
      cost.

   b. There is no provision for federal income or excise 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. 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. 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 proportion of the value of shares outstanding of
      each class. Class-specific expenses, which include distribution and
      service fees and any other items that can be specifically attributed to a
      particular class, are charged directly to such class.

   e. The treatment for financial statement purposes of distributions made
      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 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.

3. Purchases and sales of portfolio securities, excluding short-term
investments, for the year ended December 31, 1994, amounted to $404,879,349 and
$204,781,130, respectively.

   At December 31, 1994, the cost of investments for federal income tax purposes
was substantially the same as the cost for financial reporting purposes, and the
tax basis gross unrealized appreciation and depreciation of portfolio securities
amounted to $63,546,002 and $3,572,284, respectively.

4. 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 0.75% per annum of the Fund's average daily net assets.

Notes to Financial Statements (continued)
- ------------------------------------------------------------------------
 
   Seligman Financial Services, Inc. (the "Distributor"), agent for the
distribution of Fund shares and an affiliate of the Manager, received
commissions of $693,835 from sales of Class A shares, after concessions of
$5,926,699 paid to dealers.

   Effective January 1, 1993, the Fund adopted an Administration, Shareholder
Services and Distribution Plan (the "Plan") with respect to Class A shares under
which 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, 1994, fees paid
aggregated $346,469, or 0.21% per annum of the average daily net assets of Class
A shares.

   Effective May 3, 1993, the Fund adopted a Plan with respect to Class D shares
under which 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 D shares for which the organizations are
responsible, and 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. For the year ended December
31, 1994, fees paid amounted to $413,527, or 1% per annum of the average daily
net assets of Class D shares.

   The Distributor is entitled to retain any CDSL imposed on certain redemptions
occurring within one year of purchase. For the year ended December 31, 1994,
such charges amounted to $34,431.

   Seligman Data Corp., owned by certain associated investment companies,
charged the Fund at cost $1,016,432 for shareholder account services.

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

   Fees of $14,500 were incurred by the Fund for legal services of Sullivan &
Cromwell, a member of which firm is a director of the Fund.

   The Fund has a compensation arrangement under which directors who receive
fees may elect to defer receiving such fees. Interest is accrued on the deferred
balances. The annual cost of such fees and interest is included in directors'
fees and expenses, and the accumulated balance thereof at December 31, 1994, of
$74,028 is included in other liabilities. Deferred fees and the related accrued
interest are not deductible for federal income tax purposes until such amounts
are paid.

5. Class-specific expenses charged to Class A and Class D during the year ended
December 31, 1994, which are included in the corresponding captions of the
Statement of Operations, were as follows:

Financial Highlights
- --------------------------------------------------------------------------------

The Fund's financial highlights are presented below. The per share operating
performance data is designed to allow investors to trace the operating
performance, on a per share basis, from the Fund's beginning net asset value to
the ending net asset value so that they can understand what effect the
individual items have on their investment, assuming it was held throughout the
period. Generally, the per share amounts are derived by converting the actual
dollar amounts incurred for each item, as disclosed in the financial statements,
to their equivalent per share amount.
 
   The total return based on net asset value measures the Fund's performance
assuming investors purchased Fund shares at net asset value as of the beginning
of the period, reinvested dividends and capital gains paid at net asset value,
and then sold their shares at the net asset value per share on the last day of
the period. The total return computations do not reflect any sales charges
investors may incur in purchasing or selling shares of the Fund. The total
returns for periods of less than one year are not annualized.

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, 1994, 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 fi-nancial 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, 1994 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, 1994, 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.

                           ARTICLES OF INCORPORATION

                                      OF

              SELIGMAN COMMUNICATIONS AND INFORMATION FUND, INC.


          FIRST:  I, the subscriber, John T. Bostelman, whose post office
address is 125 Broad Street, New York, New York 10004 being at least twenty-one

Maryland authorizing the formation of corporations, form a corporation.

          SECOND:  NAME.  The name of the corporation (which is hereinafter

engage in the business of holding, investing and reinvesting its funds in
securities, and in connection therewith, to hold part or all of its funds in
cash, to acquire by purchase, subscription, contract, exchange or otherwise, and
to own, hold for investment, resale or otherwise, sell assign, negotiate,
exchange, transfer or otherwise dispose of, or turn to account or realize upon,
and generally to deal in and with, all forms of stocks, bonds, debentures,

these Articles of Incorporation, to make payment therefor by any lawful means;
to exercise any and all rights, powers and privileges of individual ownership or
interest in respect of any and all such Securities, including the right to vote
thereon and to consent and otherwise act with respect thereto; to do any and all

value of any and all such Securities; to acquire or become interested in any
such Securities as aforesaid, irrespective of whether or not such Securities be
fully paid or subject to further payments, and to make payments thereon as
called for or in advance of calls or otherwise;

          And, in general, to do any or all such other things in connection with
the objects and purposes of the Corporation hereinbefore set forth, as are, in
the opinion of the Board of Directors of the Corporation, necessary, incidental,
relative or conducive to the attainment of such objects and purposes; and to do
such acts and things, and to exercise any and all such powers to the same extent
as a natural person might or could lawfully do to the full extent authorized or
permitted to a corporation under any laws that may be now or hereafter
applicable or available to the Corporation.

                                      -1-
<PAGE>
 
          In addition, the Corporation may issue, sell, acquire through
purchase, exchange, or otherwise, hold, dispose of, resell, transfer, reissue or
cancel shares of its capital stock in any manner and to the extent now or
hereafter permitted by the laws of Maryland and by these Articles of
Incorporation.

          The foregoing matters shall be construed as purposes, objects and
powers, and none of such matters shall be in anywise limited by reference to, or
inference from, any other of such matters or any other Article of these Articles
of Incorporation, but shall be regarded as independent purposes, objects and
powers and the enumeration of specific purposes, objects and powers shall not be
construed to limit or restrict in any manner the meaning of general terms or the
general powers of the Corporation now or hereafter conferred by the laws of the
State of Maryland, nor shall the expression of one thing be deemed to exclude
another, although it be of like nature, not expressed.

          Nothing herein contained shall be construed as giving the Corporation
any rights, powers or privileges not permitted to it by law.

          FOURTH:  PRINCIPAL OFFICE.  The post office address of the principal
office of the Corporation in this State is c/o The Corporation Trust
Incorporated, 32 South Street, Baltimore, Maryland 21202.  The resident agent of
the Corporation is The Corporation Trust Incorporated, the post office address
of which is 32 South Street, Baltimore, Maryland  21202.  Said resident agent is
a corporation of the State of Maryland.

          FIFTH:  CAPITAL STOCK.

          A.  The total number of shares of capital stock of all classes which
the Corporation has authority to issue is 100,000,0000 shares of capital stock
(par value $.10 per share), amounting to an aggregate par value of $10,000,000.
All of such shares are initially classified as "Common Stock."  The Board of
Directors may classify or reclassify any unissued shares of capital stock (which
classes shall share ownership of specifically allocated assets buy may have
differing dividend, distribution, and other rights, as hereinafter contemplated)
whether or not such shares have previously been classified or reclassified from
time to time by setting or changing in any one or more respects the preferences,
conversion or other rights, voting powers, restrictions, limitations as to
dividends, qualifications, or terms or conditions of redemption of such shares
of stock.

          B.  No holder of shares of the capital stock of the Corporation shall
be entitled as such, as a matter of right, to purchase or subscribe for any part
of any new or additional issue of stock or securities of the Corporation.

          C.  All shares of the capital stock of the Corporation now or
hereafter authorized shall be "subject to redemption" and "redeemable", in the
sense used in the General Laws of the State of Maryland authorizing the
formation of corporations.  In the absence of any contrary specification as to
the purpose for which shares of the capital stock of the Corporation are
redeemed or repurchased by it, all shares of any class so redeemed or
repurchased shall thereafter have the status of authorized but unissued capital
stock of such class of the Corporation.

          D.  The terms of the Common Stock as set by the Board of Directors are
as follows:

          (a) The Common Stock of the Corporation shall have two classes of
     shares, which shall be designated Class A and Class D. The number of
     authorized shares of Class A Common Stock and Class D Common Stock shall
     each consist of the sum of x and y where: x equals the 

                                      -2-
<PAGE>
 
     issued and outstanding shares of such class; and y equals one-half 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 and Class D Common Stock shall not exceed the authorized number
     of shares of Common Stock (i.e., 100,000,000 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); 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 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 of 1940, as amended (the
          "Investment Company Act") and applicable rules and regulations of the
          National Association of Securities Dealers, Inc. (the "NASD").

               (2) 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.

               (3) 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.

               (4) 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 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.

               (5) As to any matter with respect to which a separate vote of any
          Class of a Series 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 (3) above), such requirement as to a separate vote by that
          Class shall apply in lieu of a single Class voting, and, if permitted
          by the Investment Company Act or any rules, regulations or orders
          thereunder and the Maryland General Corporation Law, the Classes shall
          vote together as a single Class on any such matter that shall have the
          same effect on each such Class.  As to any matter that does not 

                                      -3-
<PAGE>
 
          affect the interest of a particular Class, only the holders of shares
          of the affected Class shall be entitled to vote.

          SIXTH:  DIRECTORS.  The number of directors of the Corporation shall
initially be ten and the names of the directors who shall act as such until the
first annual meeting or until their successors are elected and qualify are as
follows:

          Lane W. Adams             Douglas R. Nichols, Jr.
          Fred E. Brown             Robert G. Olmsted
          Stanley R. Currie         James C. Pitney
          William McBride Love      Ronald T. Schroeder
          John E. Merow             Robert L. Shafer

The number of directors in office may be changed from time to time in such
manner as the By-Laws of the Corporation shall provide.

          SEVENTH:  PROVISIONS FOR DEFINING, LIMITING AND REGULATING THE POWERS
                    OF THE CORPORATION, DIRECTORS AND SHAREHOLDERS.

          A.  BOARD OF DIRECTORS.  The Board of Directors shall have the general
management and control of the business and property of the Corporation, and may
exercise all the powers of the Corporation, except such as are by law or by
these Articles of Incorporation or by the By-Laws conferred upon or reserved to
the shareholders.  In furtherance and not in limitation of the powers conferred
by law, the Board of Directors is hereby empowered:

          1.  To authorize the issuance and sale, from time to time, of shares
     of the capital stock of the Corporation, whether for cash at not less than
     the par value thereof or for such other consideration as the Board of
     Directors may deem advisable, in the manner and to the extent now or
     hereafter permitted by the laws of Maryland; provided, however, that the
     consideration (or the value thereof as determined by the Board of
     Directors) per share to be received by the Corporation upon the sale of any
     shares of its capital stock (including treasury shares) shall not be less
     than the net asset value (determined as provided in Article NINTH hereof)
     per share of such capital stock outstanding at the time (determined by the
     Board of Directors) as of which the computation of such net asset value
     shall be made.

          2.  To authorize the execution and performance by the Corporation of
     an agreement or agreements, which may be exclusive contracts, with J. & W.
     Seligman and Co. Marketing, Inc., a Delaware corporation, or any other
     person, as distributor, providing for the distribution of shares of the
     capital stock of the Corporation.

          3.  To specify, in instances in which it may be desirable, that shares
     of the capital stock of the Corporation repurchased by it are not
     repurchased for retirement and to specify the purposes for which such
     shares are repurchased.

          4.  To authorize the execution and performance by the Corporation of
     an agreement or agreements with J. & W. Seligman & Co. Incorporated
     ("Seligman") or any other person whereby, subject to the control of the
     Board of Directors, the investment and other operations of the Corporation
     shall be managed by Seligman or such other person.

                                      -4-
<PAGE>
 
          The Corporation may in its By-Laws confer powers on the Board of
Directors in addition to the foregoing and in addition to the powers expressly
conferred by statute.

          B.  VOTING POWERS.  The presence in person or by proxy of the holders
of one-third of the shares of the capital stock of the Corporation outstanding
and entitled to vote thereat shall constitute a quorum at any meeting of the
shareholders.  If at any meeting of the shareholders there be less than a quorum
present, the shareholders present at such meeting may, without further notice,
adjourn the same from time to time until a quorum shall attend, but no business
shall be transacted at any such adjourned meeting, except such as might have
been lawfully transacted had the meeting not been adjourned.  Notwithstanding
any provision of law requiring any action to be taken or authorized by the
holders of a greater proportion than a majority of the shares of capital stock
of the Corporation entitled to vote thereon, such action shall be valid and
effective if taken or authorized by the affirmative vote of the holders of a
majority of the shares of the capital stock of the Corporation outstanding and
entitled to vote thereon.

          EIGHTH:  REDEMPTIONS AND REPURCHASES.

          A.  The Corporation shall under some circumstances redeem, and may
under other circumstances repurchase, shares of its capital stock as follows:

          1. OBLIGATION OF THE CORPORATION TO REDEEM SHARES:  Each holder of
     shares of any class shall be entitled at his option to require the
     Corporation to redeem all or any part of the shares of capital stock of
     that class owned by such holder, upon written or telegraphic request to the
     Corporation or its designated agent, accompanied by surrender of the
     certificate or certificates for such shares, or such other evidence of
     ownership as shall be specified by the Board of Directors, for the
     proportionate interest per share in the assets of the Corporation belonging
     to that class, or the cash equivalent thereof (being the net asset value of
     such share of that class determined as provided in Article NINTH hereof,
     less the amount of any applicable contingent deferred sales charge payable
     on such redemption), subject to and in accordance with the provisions of
     paragraph B of this Article.

          2. RIGHT OF THE CORPORATION TO REPURCHASE SHARES:  In addition the
     Board of Directors may, from time to time in its discretion, authorize the
     officers of the Corporation to repurchase shares of its capital stock,
     either directly or through an agent, subject to and in accordance with the
     provisions of paragraph B of this Article.  The price to be paid by the
     Corporation upon any such repurchase shall be determined, in the discretion
     of the Board of Directors, in accordance with any provision of the
     Investment Company Act of 1940 or any rule or regulation or order of the
     Securities and Exchange Commission thereunder.

          3.  REDEMPTION OF ACCOUNTS:  In addition the Board of Directors may,
     from time to time in its discretion, authorize the Corporation to require
     the redemption of all or any part of the outstanding Shares of any Class or
     all or any part of the outstanding Shares of any shareholder, for the
     proportionate interest per Share in the assets of the Corporation belonging
     to that Class or shareholder, or the cash equivalent thereof (being the net
     asset value per Share of that Class determined as provided in Article NINTH
     hereof), subject to and in accordance with the provisions of paragraph B of
     this Article, upon the sending of written notice thereof to each
     shareholder any of whose Shares are so redeemed and upon such terms and
     conditions as the Board of Directors shall deem advisable.

                                      -5-
<PAGE>
 
          B.  The following provisions shall be applicable with respect to
redemptions and repurchases of shares of the capital stock of the Corporation
pursuant to paragraph A hereof:

          1.  Certificates of shares of capital stock to be redeemed or
     repurchased shall be surrendered in proper form for transfer, together with
     such proof of the authenticity of signatures as may be required by
     resolution of the Board of Directors.

          2.  Payment of the redemption or repurchase price by the Corporation
     or its designated agent shall be made in cash within seven days after the
     time used for determination of the redemption or repurchase price, but in
     no event prior to delivery to the Corporation, or its designated agent, of
     the certificate or certificates for the shares of capital stock so redeemed
     or repurchased or of such other evidence of ownership as shall be specified
     by the Board of Directors; except that any payment may be made in whole or
     in part in securities or other assets of the Corporation, if, in the event
     of the closing of the New York Stock Exchange or the happening of any event
     at any time prior to actual payment which makes the liquidation of
     Securities in orderly fashion impractical or impossible, the Board of
     Directors shall determine that payment in cash would be prejudicial to the
     best interests of the remaining shareholders of the Corporation.  In making
     any such payment in whole or in part in Securities or other assets of the
     Corporation, the Corporation shall, as nearly as may be practicable,
     deliver Securities or other assets of a gross value (determined in the
     manner provided in Article NINTH hereof) representing the same
     proportionate interest in the Securities and other assets of the
     Corporation as is represented by the shares so to be paid for.  Delivery of
     the Securities included in any such payment shall be made as promptly as
     any necessary transfers on the books of the several corporations whose
     Securities are to be delivered may be made.

          3.  The right of the holder of shares of capital stock redeemed or
     repurchased by the Corporation, as provided in this Article, to receive
     dividends thereon and all other rights of such holder with respect to such
     shares shall forthwith cease and terminate from and after the time as of
     which the redemption or repurchase price of such shares has been determined
     (except the right of such holder to receive (a) the redemption or
     repurchase price of such shares from the Corporation or its designated
     agent, and cash and/or in Securities or other assets of the Corporation,
     and (b) any dividend to which such holder had previously become entitled as
     the record holder of such shares on the record date from such dividend and
     with respect to shares of capital stock otherwise entitled to vote, except
     the right of such holder to vote at a meeting of shareholders such shares
     owned of record by him on the record date for such meeting).

          NINTH:  DETERMINATION OF NET ASSET VALUE.  For the purposes referred
to in Articles SEVENTH and EIGHTH hereof the net asset value of shares of the
capital stock of the Corporation shall be determined by or pursuant to the
direction of the Board of Directors in accordance with the following provisions:

          A.  Such net asset value on any day shall be computed as follows:

          The net asset value of each share of such stock shall be the quotient
     obtained by dividing the "net value of the assets" of the Corporation by
     the total number of shares at the time deemed to be outstanding (including
     shares sold whether paid for and issued or not, and excluding shares
     redeemed or repurchased on the basis of previous determined values, whether
     paid for, received and held in treasury, or not).

                                      -6-
<PAGE>
 
          The "net value of the assets" shall be the "gross value" after
     deducting the amount of all expenses incurred and accrued and unpaid, such
     reserves as may be set up to cover taxes and any other liabilities, and
     such other deductions as in the opinion of the officers of the Corporation
     are in accordance with accepted accounting practice.

          The "gross value" of the assets shall be the amount of all cash and
     receivables and the market value of all Securities and other assets held by
     the Corporation at the time as of which the determination is made.
     Securities held shall be valued at market value or, in the absence of
     readily available market quotations, at fair value, both as determined
     pursuant to methods approved by the Board of Directors and in accordance
     with applicable statutes and regulations.

          B.  The Board of Directors is empowered, in its absolute discretion,
to establish other methods for determining such net asset value whenever such
other methods are deemed by it to be necessary or desirable and are consistent
with any provision of the Investment Company Act of 1940 or any rule or
regulation or order of the Securities and Exchange Commission thereunder.  The
time or times as of which the net asset value of shares of the capital stock of
the Corporation shall be computed shall be such time or times as may be
determined by or pursuant to the direction of the Board of Directors.

liabilities of the Corporation, as to the amount of the net income of the
Corporation for any period or amounts at any time legally available for the
payment of dividends, as to the amount of any reserves or charges set up and the
propriety thereof, as to the time of or purpose for creating any reserves or
charges, as to the use, alteration or cancellation of any reserves or charges

thereafter required to be paid or discharged), as to the price or closing bid or
asked price of any Security owned or held by the Corporation, as to the market

as to the extent to which it is practicable to deliver the proportionate
interest in the Securities and other assets of the Corporation represented by
any shares redeemed or repurchased in payment for any such shares, as to the
method of payment for any such shares, redeemed or repurchased, or as to any
other matters relating to the issue, sale, redemption, repurchase, and/or other
acquisition or disposition of Securities or shares of capital stock of the
Corporation shall be final and conclusive and shall be binding upon the
Corporation and all holders of shares of its capital stock, past, present and
future, and shares of the capital stock of the Corporation are issued and sold
on the condition and understanding that any and all such determinations shall be
binding as aforesaid.  No provision of these Articles of Incorporation shall be
effective to (a) bind any person waive compliance with any provision of the
Securities Act of 1933 or the Investment Company Act of 1940 or of any valid
rule, regulation or order of the Securities and Exchange Commission thereunder,
or (b) protect or purport to protect any director or officer of the Corporation
against any liability to the Corporation or its security holders to which he
would otherwise be subject by reason of willful misfeasance, bad faith, gross
negligence or reckless disregard of the duties involved in the conduct of his
office.

          ELEVENTH:  AMENDMENTS.  The Corporation reserves the right to take any
lawful action and to make any amendment of these Articles of Incorporation,

reserves the right to make any amendment of these Articles of Incorporation in
any form, manner or substance now or hereafter authorized or permitted by law.

          TWELFTH:  LIABILITY.  A director or officer of the Corporation shall
not be liable to the Corporation or its shareholders for monetary damages for
breach of fiduciary duty as a Director or Officer, except to the extent such
exemption from liability or limitation thereof is not permitted by law
(including the Investment Company Act of 1940 as currently in effect or as the
same may hereafter be amended).

          No amendment, modification or repeal of this Article Twelfth shall

(including the Investment Company Act of 1940 as currently in effect or as the
same may hereafter be amended) any person made or threatened to be made a party

serves or served at the request of the Corporation any other enterprise as a
Director, Officer or employee.  To the fullest extent permitted by law
(including the Investment Company Act of 1940 as currently in effect or as the

defending any such action, suit or proceeding shall be paid or reimbursed by the
Corporation promptly upon receipt by it of an undertaking of such person to

person by this Article shall be enforceable against the Corporation by such
person who shall be presumed to have relied upon it in serving or continuing to
serve as a Director, Officer or employee as provided above.  No amendment of

                             MANAGEMENT AGREEMENT

          MANAGEMENT AGREEMENT, dated as of December 29, 1988, between SELIGMAN
COMMUNICATIONS AND INFORMATION FUND, INC., a Maryland corporation (the
"Corporation"), and J. & W. SELIGMAN & CO. INCORPORATED, a Delaware corporation
(the "Manager").

          In consideration of the mutual agreements herein made, the parties
hereto agree as follows:

          1.  DUTIES OF THE MANAGER.  The Manager shall manage the affairs of
the Corporation including, but not limited to, continuously providing the
Corporation with investment management, including investment research, advice
and supervision, determining which securities shall be purchased or sold by the
Corporation, making purchases and sales of securities on behalf of the
Corporation and determining how voting and other rights with respect to
securities of the Corporation shall be exercised, subject in each case to the
control of the Board of Directors of the Corporation and in accordance with the
objectives, policies and principles set forth in the Registration Statement and
Prospectus of the Corporation and the requirements of the Investment Company Act
of 1940 (the "Act") and other applicable law.  In performing such duties, the
Manager shall provide such office space, such bookkeeping, accounting, internal
legal, clerical, secretarial and administrative services (exclusive of, and in
addition to, any such services provided by any others retained by the
Corporation) and such executive and other personnel as shall be necessary for
the operations of the Corporation.  The Corporation understands that the Manager
also acts as the manager of the investment companies in the Seligman Group.

          Subject to Section 36 of the Act, the Manager shall not be liable to
the Corporation 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 the management of
the Corporation and the performance of its duties under this Agreement except
for willful misfeasance, bad faith or gross negligence in the performance of its
duties or by reason of reckless disregard of its obligations and duties under
this Agreement.

          2.  EXPENSES.  The Manager shall pay all of its expenses arising from
the performance of its obligations under Section 1 and shall pay any salaries,
fees and expenses of the directors of the Corporation who are employees of the
Manager or its affiliates.  The Manager shall not be required to pay any other
expenses of the Corporation, including, but not limited to, direct charges
relating to the purchase and sale of portfolio securities, interest charges,
fees and expenses of independent attorneys and auditors, taxes and governmental
fees, cost of stock certificates and any other expenses (including clerical
expenses) of issue, sale, repurchase or redemption of shares, expenses of
registering and qualifying shares for sale, expenses of printing and
distributing reports, notices and proxy materials to shareholders, expense of
corporate data processing and related services, shareholder recordkeeping and
shareholder 
<PAGE>
 
account services, expenses of printing and filing reports and other documents
filed with governmental agencies, expenses of printing and distributing
prospectuses, expenses of annual and special shareholders' meetings, fees and
disbursements of transfer agents and custodians, expenses of disbursing
dividends and distributions, fees and expenses of directors of the Corporation
who are not employees of the Manager or its affiliates, membership dues in the
Investment Company Institute, insurance premiums and extraordinary expenses such
as litigation expenses.

          3.  COMPENSATION.  (a) As compensation for the services performed and
the facilities and personnel provided by the Manager pursuant to Section 1, the
Corporation will pay to the Manager promptly after the end of each month a fee,
calculated on each day during such month, equal to an annual rate of 0.75% of
the net assets of the Corporation at the close of business on the previous day.

          (b) If the Manager shall serve hereunder for less than the whole of
any month, the fee hereunder shall be prorated.

          4.  PURCHASE AND SALE OF SECURITIES.  The Manager shall purchase
securities from or through and sell securities to or through such persons,
brokers or dealers (including the Manager or an affiliate of the Manager) as the
Manager shall deem appropriate in order to carry out the policy with respect to
brokerage as set forth in the Registration Statement and Prospectus of the
Corporation or as the Board of Directors of the Corporation may direct from time
to time.  In providing the Corporation with investment management and
supervision, it is recognized that the Manager will seek the most favorable
price and execution, and, consistent with such policy, may give consideration to
the research, statistical and other services furnished by brokers or dealers to
the Manager for its use, to the general attitude of brokers or dealers toward
investment companies and their support of them, and to such other considerations
as the Board of Directors of the Corporation may direct or authorize from time
to time.

          Notwithstanding the above, it is understood that it is desirable for
the Corporation that the Manager have access to supplemental investment and
market research and security and economic analysis provided by brokers who
execute brokerage transactions at a higher cost to the Corporation than may
result when allocating brokerage to other brokers on the basis of seeking the
most favorable price and execution.  Therefore, the Manager is authorized to
place orders for the purchase and sale of securities for the Corporation with
such brokers, subject to review by the Corporation's Board of Directors from
time to time with respect to the extent and continuation of this practice.  It
is understood that the services provided by such brokers may be useful to the
Manager in connection with its services to other clients as well as the
Corporation.

          The placing of purchase and sale orders may be carried out by the
Manager or any wholly-owned subsidiary of the Manager.
<PAGE>
 
          If, in connection with purchases and sales of securities for the
Corporation, the Manager or any subsidiary of the Manager may, without material
risk, arrange to receive a soliciting dealer's fee or other underwriter's or
dealer's discount or commission, the Manager shall, unless otherwise directed by
the Board of Directors of the Corporation, obtain such fee, discount or
commission and the amount thereof shall be applied to reduce the compensation to
be received by the Manager pursuant to Section 3 hereof.

          Nothing herein shall prohibit the Board of Directors of the
Corporation from approving the payment by the Corporation of additional
compensation to others for consulting services, supplemental research and
security and economic analysis.

          5.  TERM OF AGREEMENT.  This Agreement shall continue in full force
and effect until December 29, 1989 and from year to year thereafter if such
continuance is approved in the manner required by the Act and the Manager shall
not have notified  the Corporation in writing at least 60 days prior to such
December 29 or prior to December 29 of any year thereafter that it does not
desire such continuance.  This Agreement may be terminated at any time, without
payment of penalty by the Corporation, on 60 days' written notice to the Manager
by vote of the Board of Directors of the Corporation or by vote of a majority of
the outstanding voting securities of the Corporation (as defined by the Act).
This Agreement shall automatically terminate in the event of its assignment (as
defined by the Act).

          6.  RIGHT OF MANAGER IN CORPORATE NAME.  The Manager and the
Corporation each agree that the word "Seligman", which comprises a component of
the Corporation's name, is a property right of the Manager.  The Corporation
agrees and consents that (i) it will only use the word "Seligman" as a component
of its corporate name and for no other purpose, (ii) it will not purport to
grant to any third party the right to use the word "Seligman" for any purpose,
(iii) the Manager or any corporate affiliate of the Manager may use or grant to
others the right to use the word "Seligman", or any combination or abbreviation
thereof, as all or a portion of a corporate or business name or for any
commercial purpose, including a grant of such right to any other investment
company, and at the request of the Manager, the Corporation will take such
action as may be required to provide its consent to the use of the word
"Seligman", or any combination or abbreviation thereof, by the Manager or any
corporate affiliate of the Manager, or by any person to whom the Manager or an
affiliate of the Manager shall have granted the right to such use; and (iv) upon
the termination of any management agreement into which the Manager and the
Corporation may enter, the Corporation shall, upon request by the Manager,
promptly take such action, at its own expense, as may be necessary to change its
corporate name to one not containing the word "Seligman" and following such
change, shall not use the word "Seligman", or any combination thereof, as a part
of its corporate name or for any other commercial purpose, and shall use its
best efforts to cause its officers, directors and stockholders to take any and
all actions which the Manager may request to effect the foregoing and to
reconvey to the Manager any and all rights to such word.
<PAGE>
 
          7.  MISCELLANEOUS.  This Agreement shall be governed by and construed
in accordance with the laws of the State of New York.  Anything herein to the
contrary notwithstanding, this Agreement shall not be construed to require, or
to impose any duty upon either of the parties, to do anything in violation of
any applicable laws or regulations.
<PAGE>
 
          IN WITNESS WHEREOF, the Corporation and the Manager have caused this
Agreement to be executed by their duly authorized officers as of the date first
above written.

              SELIGMAN COMMUNICATIONS AND INFORMATION FUND, INC.


SUBADVISORY AGREEMENT, dated as of May 19, 1994 between J. & W. SELIGMAN & CO.
INCORPORATED, a Delaware corporation (the "Manager") and SELIGMAN HENDERSON CO.,
a New York general partnership (the "Subadviser").

WHEREAS, the Manager has entered into a Management Agreement dated December 29,
1988 (the "Management Agreement") with Seligman Communications and Information
Fund, Inc. (the "Fund"), an open-end diversified management investment company
registered under the Investment Company Act of 1940, as amended (the "1940
Act"), pursuant to which the Manager will render investment management services
to the Fund, and to administer the business and other affairs of the Fund; and

WHEREAS, the Manager desires to retain the Subadviser to provide investment
management services to the Fund, and the Subadviser is willing to render such
investment management services.

NOW, THEREFORE, in consideration of the mutual covenants contained herein, the
parties hereto agree as follows:

1.  DUTIES OF THE SUBADVISER.  The Subadviser will provide the Fund with
investment management services with respect to assets of the Fund if, and to the
extent, designated by the Manager (such designated assets, "Qualifying Assets").
Such services shall include investment research, advice and supervision,
determining which securities shall be purchased or sold by the Fund, making
purchases and sales of securities on behalf of the Fund and determining how
voting and other rights with respect to securities of the Fund shall be
exercised, subject in each case to the control of the Board of Directors of the
Fund and in accordance with the objectives, policies and principles set forth in
the Registration Statement and Prospectus(es) of the Fund and the requirements
of the 1940 Act and other applicable law.

Subject to Section 36 of the 1940 Act, the Subadviser shall 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 the management of the Fund and the
performance of its duties under this Agreement except for willful misfeasance,
bad faith or gross negligence in the performance of its duties or by reason of
reckless disregard of its obligations and duties under this Agreement.

2.  EXPENSES.  The Subadviser shall pay all of its expenses arising from the
performance of its obligations under Section 1.

3.  COMPENSATION

    (a)  As compensation for the services performed and the facilities and
         personnel provided by the Subadviser pursuant to Section 1, the Manager
         will pay to the Subadviser each month a fee, equal to .75% per annum of
         the average monthly Net Qualifying Assets of the Fund.
<PAGE>
 
    (b)  As used herein, the term "Net Qualifying Assets" means the Qualifying
         Assets less related liabilities as designated by the Manager.

    (c)  Average monthly Net Qualifying Assets shall be determined, for any
         month, by taking the average of the value of the Net Qualifying Assets
         as of the (i) opening of business on the first day of such month and
         (ii) close of business on the last day of such month.

    (d)  If the Subadviser shall serve hereunder for less than the whole of any
         month, the fee hereunder shall be prorated.

4.  PURCHASE AND SALE OF SECURITIES.  The Subadviser shall purchase securities
from or through and sell securities to or through such persons, brokers or
dealers as the Subadviser shall deem appropriate in order to carry out the
policy with respect to allocation of portfolio transactions as set forth in the
Registration Statement and Prospectus(es) of the Fund or as the Board of
Directors of the Fund may direct from time to time.  In providing the Fund with
investment management and supervision, it is recognized that the Subadviser will
seek the most favorable price and execution, and, consistent with such policy,
may give consideration to the research, statistical and other services furnished
by brokers or dealers to the Subadviser for its use, to the general attitude of
brokers or dealers toward investment companies and their support of them, and to
such other considerations as the Board of Directors of the Fund may direct or
authorize from time to time.

Notwithstanding the above, it is understood that it is desirable for the Fund
that the Subadviser have access to supplemental investment and market research
and security and economic analysis provided by brokers who execute brokerage
transactions at a higher cost to the Fund than may result when allocating
brokerage to other brokers on the basis of seeking the most favorable price and
execution.  Therefore, the Subadviser is authorized to place orders for the
purchase and sale of securities of the Fund with such brokers, subject to review
by the Fund's Board of Directors from time to time with respect to the extent
and continuation of this practice.  It is understood that the services provided
by such brokers may be useful to the Subadviser in connection with its services
to other clients as well as the Fund.

If, in connection with purchases and sales of securities for the Fund, the
Subadviser may, without material risk, arrange to receive a soliciting dealer's
fee or other underwriter's or dealer's discount or commission, the Subadviser
shall, unless otherwise directed by the Board of Directors of the Fund, obtain
such fee, discount or commission and the amount thereof shall be applied to
reduce the compensation to be received by the Subadviser pursuant to Section 3
hereof.

Nothing herein shall prohibit the Board of Directors of the Fund from approving
the payment by the Fund of additional compensation to others for consulting
services, supplemental research and security and economic analysis.

5.  TERM OF AGREEMENT.  This Agreement shall continue in full force and effect
until December 31, 1995, and from year to year thereafter if such continuance is
approved in the manner  required by the 1940 Act, and if the Subadviser shall
not have notified the Manager in writing at least 60 days prior to such date or
prior to December 31 of any year thereafter that it does 
<PAGE>
 
not desire such continuance. This Agreement may be terminated at any time,
without payment of penalty by the Fund, on 60 days' written notice to the
Subadviser by vote of the Board of Directors of the Fund or by vote of a
majority of the outstanding voting securities of the Fund (as defined by the
1940 Act). This Agreement will automatically terminate in the event of its
assignment (as defined by the 1940 Act) or upon the termination of the
Management Agreement.

6.  AMENDMENTS.  This Agreement may be amended by consent of the parties hereto
provided that the consent of the Fund is obtained in accordance with the
requirements of the 1940 Act.

7.  MISCELLANEOUS.  This Agreement shall be governed by and construed in
accordance with the laws of the State of New York.  Anything herein to the
contrary notwithstanding, this Agreement shall not be construed to require, or
