  Seligman Communications and Information Fund, Inc. (the "Fund") is a mutual
fund which invests to produce capital gain. The Fund invests primarily in se-
curities of companies in the communications, information and related indus-
tries. Investment advisory and management services are provided to the Fund by
J. & W. Seligman & Co. Incorporated (the "Manager") and, to the extent re-
quested by the Manager in respect of foreign assets, Seligman Henderson Co.
(the "subadvisor"). The Fund's distributor is Seligman Financial Services,
Inc., an affiliate of the Manager. For a description of the Fund's investment
objective and policies, including the risk factors associated with an invest-
ment in the Fund, see "Investment Objective, Policies And Risks." There can be
no assurance that the Fund's investment objective will be achieved.     
   
  The Fund offers three classes of shares. Class A shares are sold subject to
an initial sales load of up to 4.75% and an annual service fee currently
charged at a rate of up to .25% of the average daily net asset value of the
Class A shares. Class B shares are sold without an initial sales load but are
subject to a contingent deferred sales load ("CDSL") of 5% on redemptions in
the first year after purchase of such shares, declining to 1% in the sixth
year and 0% thereafter, an annual distribution fee of up to .75% and an annual
service fee of up to .25% of the average daily net asset value of the Class B
shares. Class B shares will automatically convert to Class A shares on the
last day of the month that precedes the eighth anniversary of their date of
purchase. Class D shares are sold without an initial sales load but are sub-
ject to a CDSL of 1% imposed on certain redemptions within one year of pur-
chase, an annual distribution fee of up to .75% and an annual service fee of
up to .25% of the average daily net asset value of the Class D shares. Any
CDSL payable upon redemption of Class B or Class D shares will be assessed on
the lesser of the current net asset value or the original purchase price of
the shares redeemed. See "Alternative Distribution System." Shares of the Fund
may be purchased through any authorized investment dealer.

  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 loads on Class B and Class D shares
are one-time charges paid only if shares are redeemed within six years or one
year of purchase, respectively. The management fees for Class A and Class D
shares have been restated to reflect the increase in the management fee rate
payable by the Fund, which was approved by shareholders on February 7, 1996
and became effective February 8, 1996. The "Other Expenses" disclosed for
Class D shares have been restated to reflect the expense allocation methodol-
ogy currently being used by the Fund. For more information concerning reduc-
tions in sales loads and for a more complete description of the various costs
and expenses, see "Purchase Of Shares," "Redemption Of Shares" and "Management
Services" herein. The Fund's Administration, Shareholder Services and Distri-
bution Plan to which the caption "12b-1 Fees" relates, is discussed under "Ad-
ministration, Shareholder Services and Distribution Plan" herein.

You would pay the following expenses on a
 $1,000 investment,
 assuming (1) 5% annual return and (2) re-
 demption at the end
 of each time period..................Class A  $65     $100    $138     $245

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.
   
 * Expenses for Class B shares are estimated because no shares of that Class
   were outstanding in the year ended December 31, 1995.     
   
** Includes an annual distribution fee of up to .75% and an annual service fee
   of up to .25%. 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 B and Class D shares of the Fund may not exceed 6.25% of
   total gross sales, subject to certain exclusions. The maximum sales charge
   rule is applied separately to each class. The 6.25% limitation is imposed
   on the Fund rather than on a per shareholder basis. Therefore, a long-term
   Class B or Class D shareholder of the Fund may pay more in total sales
   loads (including distribution fees) than the economic equivalent of 6.25%
   of such shareholder's investment in such shares.     
   
 + Assuming (1) 5% annual return and (2) no redemption at the end of the peri-
   od, the expenses on a $1,000 investment would be $26 for 1 year, $78 for 3
   years and $134 for 5 years. The expenses shown for the ten-year period re-
   flect the conversion of Class B shares to Class A shares after 8 years.
       
   
++ Assuming (1) 5% annual return and (2) no redemption at the end of one year,
   the expenses on a $1,000 investment would be $26.

                              FINANCIAL HIGHLIGHTS
   
  The financial highlights for the Fund's Class A and Class D for the periods
presented below have been audited by Deloitte & Touche LLP, independent audi-
tors. This information, which is derived from the financial and accounting rec-
ords of the Fund, should be read in conjunction with the financial statements
and notes contained in the Fund's 1995 Annual Report, which is incorporated by
reference in the Fund's Statement of Additional information, copies of which
may be obtained free of charge by calling or writing the Fund at the telephone
numbers or address provided on the cover page of this Prospectus. Financial
highlights are not presented for the Class B shares because no shares of that
class were outstanding during the periods set forth 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 begin-
ning net asset value to its ending net asset value so that they may 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 con-
verting 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 as-
suming investors purchased Fund shares at net asset value as of the beginning
of the period, invested dividends and capital gains paid at net asset value and
then sold their shares at the net asset value 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 peri-
ods of less than one year are not annualized.

ALTERNATIVE DISTRIBUTION SYSTEM
   
  The Fund offers three classes of shares. Class A shares are sold to invest-
ors who have concluded that they would prefer to pay an initial sales load and
have the benefit of lower continuing fees. Class B shares are sold to invest-
ors choosing to pay no initial load, a higher distribution fee and a CDSL with
respect to redemptions within six years of purchase and who desire shares to
convert automatically to Class A shares after eight years. Class D shares are
sold to investors choosing to pay no initial sales load, a higher distribution
fee and with, respect to redemptions within one year of purchase, a CDSL. The
Alternative Distribution System allows investors to choose the method of pur-
chasing 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 cir-
cumstances. Investors should determine whether under their particular circum-
stances it is more advantageous to incur an initial sales load and be subject
to lower ongoing fees, as discussed below, or to have the entire initial pur-
chase price invested in the Fund with the investment thereafter being subject
to higher ongoing fees and either a CDSL for a six-year period with automatic
conversion to Class A shares after eight years or a CDSL for a one-year period
with no automatic conversion to Class A shares.     
 
  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, however, 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 fees of Class B and Class D shares may exceed the initial sales load and
lower distribution 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 on Class A shares deducted at the time of purchase. Fur-
thermore, the distribution fees on Class B and Class D shares will be offset
to the extent any return is realized on the additional funds initially in-
vested therein that would have been equal to the amount of the initial sales
load on Class A shares. In addition, Class B shares will be converted automat-
ically to Class A shares after a period of approximately eight years, and
thereafter investors will be subject to lower ongoing fees. Shares purchased
through reinvestment of dividends and distributions on Class B shares also
will convert automatically to Class A shares along with the underlying shares
on which they were earned.     
   
  Alternatively, some investors might choose to have all of their funds in-
vested initially in Class B or Class D shares although remaining subject to a
higher continuing distribution fee and, for a six-year or one-year period, a
CDSL as described below. For example, an investor who does not qualify for re-
duced sales loads would have to hold Class A shares for more than 6.33 years
for the Class B or Class D distribution 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
B and 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 in-
vestment over this period of time.     
   
  Investors should bear in mind that total asset based sales charges (i.e.,
the higher continuing distribution fee plus the CDSL) on Class B shares that
are redeemed may exceed the total asset based sales charges that would be pay-
able on a purchase of the same amount of Class A or Class D shares, particu-
larly if the Class B shares are redeemed shortly after purchase or if the in-
vestor qualifies for a reduced sales load on the Class A shares.     
   
  Investors should understand that the purpose and function of the initial
sales loads with respect to Class A shares is the same as those of the de-
ferred sales loads and higher distribution fees with respect to Class     
 
                                       4
<PAGE>
 
   
B and Class D shares in that the sales loads and distribution fees applicable
to each class provide for the financing of the distribution of the shares of
the Fund.     
   
  Class B and Class D shares are subject to the same ongoing distribution fees
but Class D shares are subject to a CSDL for a shorter period of time (one
year as opposed to six years) than Class B shares. However, unlike Class D
shares, Class B shares automatically convert to Class A shares, which are sub-
ject to lower ongoing distribution fees.     
   
  The three classes of shares represent interests in the same portfolio of in-
vestments, have the same rights and are generally identical in all respects
except that each class bears its separate distribution and, potentially, cer-
tain 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 Investment
Company Act of 1940, as amended (the "1940 Act") or Maryland law. The net in-
come 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 B and Class D shares bear higher distribution fees, which will
cause the Class B and Class D shares to pay lower dividends than the Class A
shares. The three classes also have separate exchange privileges.     
   
  The Directors of the Fund believe that no conflict of interest currently ex-
ists between the Class A, Class B and Class D shares. On an ongoing basis, the
Directors, in the exercise of their fiduciary duties under the 1940 Act, and
Maryland law, will seek to ensure that no such conflict arises. For this pur-
pose, the Directors will monitor the Fund for the existence of any material
conflict among the classes and will take such action as is reasonably neces-
sary to eliminate any such conflicts that may develop.     
   
  DIFFERENCES BETWEEN CLASSES. The primary differences between Class A, Class
B and Class D shares are their sales load structures and ongoing expenses as
set forth below. The primary differences between Class B and Class D shares
are that Class D shares are subject to a shorter CDSL period but Class B
shares automatically convert to Class A shares after eight years, resulting in
a reduction in ongoing fees. Investors in Class B shares should take into ac-
count whether they intend to redeem their shares within the CDSL period and,
if not, whether they intend to remain invested until the end of the conversion
period and thereby take advantage of the reduction in ongoing fees resulting
from the conversion to Class A shares. Other investors, however, may elect to
purchase Class D shares if they determine that it is advantageous to have all
their assets invested initially and they are uncertain as to the length of
time they intend to hold their assets in the Fund or another mutual fund in
the Seligman Group for which the exchange privilege is available. Although
Class D shareholders are subject to a shorter CDSL period at a lower rate,
they forgo the Class B automatic conversion feature, making their investment
subject to higher distribution fees for an indefinite period of time. Each
class has advantages and disadvantages for different investors, and investors
should choose the class that best suits their circumstances and their objec-
tives.

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.
 
  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. The Fund may pledge its assets only to the extent necessary to
effect permitted borrowings of up to 15% of its total assets on a secured ba-
sis. These limits may be     
 
                                       6
<PAGE>
 
changed only by a vote of the shareholders. Current asset value coverage of
three times any amount borrowed is required at all times.
 
  Borrowed money creates an opportunity for greater capital appreciation, but
at the same time increases exposure to capital risk. The net cost of any money
borrowed would be an expense that otherwise would not be incurred, and this 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.
   
  ILLIQUID 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 Manager, acting pursu-
ant to procedures approved by the Fund's Board of Directors, may determine,
when appropriate, that specific Rule 144A securities are liquid and not subject
to the 15% limitation on illiquid securities. Should this determination be
made, the Manager acting pursuant to such procedures will carefully monitor the
security (focusing on such factors, among others, as trading activity and
availability of information) to determine that the Rule 144A security continues
to be liquid. It is not possible to predict with assurance exactly how the mar-
ket for restricted securities offered and sold under Rule 144A will develop.
This investment practice could have the effect of increasing the level of illi-
quidity in the Fund, if, and 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 Depositary Receipts ("ADRs"), Euro-
pean Depositary Receipts ("EDRs") or Global Depositary Receipts ("GDRs") (col-
lectively, "Depositary Receipts").     
   
  Foreign investments may be affected favorably or unfavorably by changes in
currency rates and exchange control regulations. There may be less information
available about a foreign company than about a U.S. company and foreign compa-
nies may not be subject to reporting standards and requirements comparable to
those applicable to U.S. companies. Foreign securities may not be as liquid as
U.S. securities. Securities of foreign companies may involve greater market
risk than securities of U.S. companies, and foreign brokerage commissions and
custody fees are generally higher than in the United States. Investments in
foreign securities may also be subject to local economic or political risks,
political instability and possible nationalization of issuers. Depositary Re-
ceipts are instruments generally issued by domestic banks or trust companies
that represent the deposits of a security of a foreign issuer. ADRs may be pub-
licly 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. Depositary
Receipts may be issued under sponsored or unsponsored programs. In sponsored
programs, the issuer has made arrangements to have its securities traded in the
form of a Depositary Receipt. In unsponsored programs, the issuers may not be
directly involved in the creation of the program. Although regulatory require-
ments with     
 
                                       7
<PAGE>
 
   
respect to sponsored and unsponsored Depositary Receipt programs are generally
similar, the issuers of securities represented by unsponsored Depositary Re-
ceipts are not obligated to disclose material information in the United States,
and therefore, the import of such information may not be reflected in the mar-
ket value of such receipts. The Fund may invest up to 10% of its total assets
in foreign securities that it holds directly, but this 10% limit does not apply
to foreign securities held through Depositary Receipts which are traded in the
United States or to commercial paper and certificates of deposit issued by for-

  OPTIONS TRANSACTIONS. The Fund may purchase put options on portfolio securi-
ties in an attempt to provide a hedge against a decrease in the price of a se-
curity held by the Fund. The Fund will not purchase options for speculative
purposes. Purchasing a put option gives the Fund the right to sell, and obli-
gates the writer to buy, the underlying security at the exercise price at any
time during the option period.     
   
  When the Fund purchases an option, it is required to pay a premium to the
party writing the option and a commission to the broker selling the option. If
the option is exercised by the Fund, the premium and the commission paid may be
greater than the amount of the brokerage commission charged if the security
were to be purchased or sold directly. See "Investment Objective, Policies and
Risks" in the Statement of Additional Information.     
   
  GENERAL. Except as noted above, the foregoing investment policies are not
fundamental and the Fund's Board of Directors may change such policies without
the vote of a majority of the Fund's outstanding voting securities. As a matter
of policy, the Board would not change the Fund's investment objective of seek-
ing to produce 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 were ap-
proximately $11.9 billion at March 31, 1996. The Manager also provides invest-
ment management or advice to institutional accounts having an aggregate value
at February 29, 1996 of approximately $3.9 billion.     
 
  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.
 
                                       8

  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. The management fee, which was approved by shareholders on Feb-
ruary 7, 1996 and became effective on February 8, 1996, is equal to an annual
rate of .90% of the Fund's average daily net assets on the first $3 billion of
net assets, .85% of the Fund's average daily net assets on the next $3 billion
of net assets and .75% of the Fund's average daily net assets in excess of $6
billion.     
          
  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, 1995 amounted to 1.61% and 2.37%, respectively, of the aver-
age daily net assets of each class. No Class B shares of the Fund were out-
standing during this period.     
   
  THE SUBADVISER. The Subadviser provides investment management services to the
Fund with respect to all or a portion of the Fund's foreign investments, as
designated by the Manager ("Qualifying Assets"). The Fund has a non-fundamental
policy under which it may invest up to 10% of its total assets in foreign secu-
rities that are held directly. The 10% limit does not apply to foreign securi-
ties held through Depositary 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 Man-
ager (the "Subadvisory Agreement"), dated June 1, 1994. Pursuant to the
Subadvisory Agreement, the Subadviser, with respect to the Qualifying Assets,
provides investment management services 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 securities 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 objectives, 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 year ended December 31, 1995, the Fund did not require the services of
the Subadviser and therefore, no fees were paid by the Manager to 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., and the
Global Smaller Companies Portfolio of Seligman Portfolios, Inc. and Tri-Conti-
nental Corporation. The address of the Subadviser is 100 Park Avenue, New York,
NY 10017.     
   
  PORTFOLIO MANAGER. Paul H. Wick, a Managing Director of the Manager, is Vice
President and Portfolio Manager of the Fund and Vice President of Seligman
Portfolios, Inc. ("SPI") and Portfolio Manager of SPI's Seligman Communications
and Information Portfolio. Mr. Wick also co-manages Seligman Henderson Global
Technology Fund, a series of Seligman Henderson Global Fund Series, Inc. Mr.
Wick joined the Manager in 1987 as an Associate, Investment Research. He was
promoted to Managing Director on January 1, 1995.     
 
                                       9

  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.
   
  The Manager's discussion of the Fund's performance as well as a line graph
illustrating comparative performance information between the Fund, the Standard
& Poor's 500 Composite Stock Price Index and the Lipper Science and Technology
Fund Average is included in the Fund's 1995 Annual Report to Shareholders. Cop-
ies of the 1995 Annual Report may be obtained, without charge, by calling or
writing the Fund at the telephone numbers or address listed on the cover page
of this Prospectus.     
   
  PORTFOLIO TRANSACTIONS. The Management Agreement and Subadvisory Agreement
each recognize that in the purchase and sale of portfolio securities, the Man-
ager and the Subadviser will seek the most favorable price and execution, and,
consistent with that policy, may give consideration to the research, statisti-
cal 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 com-
mission 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 pri-
mary 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 mutual funds in the Se-
ligman 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 or Subadviser believe such changes will strengthen the Fund's port-
folio. 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, NY 10017.     
   
  The Fund issues three classes of shares: Class A shares are sold to investors
choosing the initial sales load alternative; Class B shares are sold to invest-
ors choosing to pay no initial sales load, a higher distribution fee and a CDSL
with respect to redemptions within six years of purchase and who desire shares
to convert automatically to Class A shares after eight years; and Class D
shares are sold to investors choosing no initial sales load, a higher distribu-
tion fee and a CDSL on redemptions within one year of purchase. See "Alterna-
tive 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
 
                                       10
<PAGE>
 
plans, will vary with the size of the purchase as shown in the schedule under
"Class A Shares--Initial Sales Load" below.
          
   THE MINIMUM AMOUNT FOR INITIAL INVESTMENT IN THE FUND IS $2,500; SUBSEQUENT
INVESTMENTS MUST BE IN THE MINIMUM AMOUNT OF $100 (EXCEPT FOR INVESTMENT OF
DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS). THE FUND RESERVES THE RIGHT TO RE-
TURN INVESTMENTS WHICH DO NOT MEET THESE MINIMUMS. EXCEPTIONS TO THESE MINIMUMS
ARE AVAILABLE FOR ACCOUNTS BEING ESTABLISHED CONCURRENTLY WITH THE INVEST-A-
CHECK (R) SERVICE OR THE SELIGMAN TIME HORIZON MATRIXSM.     
   
  No purchase order may be placed for Class B shares for an amount of $250,000
or more; or for Class D shares for an amount of $4,000,000 or more.     
   
  Orders received by an authorized dealer before the close of business on the
New York Stock Exchange ("NYSE") (normally, 4:00 p.m. Eastern time) and ac-
cepted 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 applica-
ble sales load. Orders accepted by dealers after the close of the NYSE, or re-
ceived 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 appli-
cable 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, B or D), A/C #107-1011. WIRE TRANSFERS MUST INCLUDE
THE PURCHASE CONFIRMATION NUMBER AND CLIENT ACCOUNT REGISTRATION AND ACCOUNT
NUMBER. Persons other than dealers who wish to wire payment should contact Se-
ligman Data Corp. for specific wire instructions. Although the Fund makes no
charge for this service, the transmitting bank may impose a wire service fee.
       
  Current 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 be
accompanied by an investment slip (provided at the bottom of shareholder ac-
count statements) and include the shareholder's name, address, account number,
name of Fund and class of shares (A, B or D). If a shareholder does not provide
the required information, Seligman Data Corp. will seek further clarification
and may be forced to return the check to the shareholder. Orders sent directly
to Seligman Data Corp. will be executed at the Fund's net asset value next de-
termined after the order is accepted plus, in the case of Class A shares, the
applicable sales load.     
   
  Seligman Data Corp. will charge a $10.00 service fee for checks returned to
it as uncollectable. This charge may be deducted from the shareholder's ac-
count. For the protection of the Fund and its shareholders, no redemption pro-
ceeds will be remitted to a shareholder with respect to 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.     
   
  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 (normally, 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.     
 
                                       11
<PAGE>
 
   
Any securities for which recent market quotations are not readily available are
valued at fair value determined in accordance with procedures approved by the
Fund's Board of Directors. Short-term holdings maturing in 60 days or less are
generally valued at amortized cost if their original maturity was 60 days or
less. Short-term holdings with more than 60 days remaining to maturity will be
valued at current market value until the 61st day prior to maturity, and will
then be valued on an amortized cost basis based on the value 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, Class B and Class D shares are substan-
tially identical, the different expenses borne by each class will result in
different net asset values and dividends. The net asset values of Class B and
Class D shares will generally be lower than the net asset value of Class A
shares as a result of the higher distribution fees charged to Class B and Class
D shares. In addition, net asset value per share of the three classes will be
affected to the extent any other expenses differ 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.

  SFSI shall pay broker/dealers, from its own resources, an additional fee in
respect of certain investments in Class A shares of the Seligman Mutual Funds
by an "eligible employee benefit plan" (as defined below under "Special Pro-
grams") which are attributable to the particular broker/dealer. The shares eli-
gible for the fee are those on which an initial front-end sales load was not
paid because either (i) the participating eligible employee benefit plan has at
least $1 million invested in the Seligman Mutual Funds or (ii) the participat-
ing employer has at least 50 eligible employees to whom such plan is made
available. The fee, which is paid monthly, is a percentage of the average daily
net asset value of eligible shares based on the length of time the shares have
been invested in an eligible Seligman Mutual Fund, as follows: for shares held
up to 1 year, .50% per annum; for shares held more than 1 year up to 2 years,
 .25% per annum; for shares held from 2 years up to 5 years, .10% per annum; and
nothing thereafter.     
 
  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 Seligman Mu-
tual Funds that are sold with a front-end 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 shares of the Seligman Mutual Funds sold with a front-end sales load
with the total net asset value of shares of those Seligman Mutual Funds already
owned that were sold with a front-end sales load and the total net     
 
                                       12
<PAGE>
 
   
asset value of shares of Seligman Cash Management Fund that were acquired by
the investor through an exchange of shares of another Seligman Mutual Funds on
which there was a front-end sales load to determine reduced sales loads in ac-
cordance with the sales load schedule. An investor or a dealer purchasing
shares on behalf 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 Se-
ligman Mutual Funds already owned that were sold with a front-end 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 Seligman Mutual Fund on
which there was a front-end sales load. An investor or a dealer purchasing
shares on behalf of an investor must indicate that the investor has existing
accounts when making investments or opening new accounts. For more information
concerning terms of Letters of Intent, see "Terms and Conditions" on page 27.
    
   
  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 family members of the foregoing) of the Fund, the other investment compa-
nies in the Seligman Group, the Manager and other companies affiliated with
the Manager. Family members are defined to include lineal descendants and lin-
eal ancestors, siblings (and their spouses and children) and any company or
organization controlled by any of the foregoing. 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.     
   
  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" (i) which have at least $1 million invested in the Seligman Group of
Mutual Funds or (ii) of employers who have at least 50 eligible 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 plan" means any plan or ar-
rangement, whether or not tax qualified, which provides for the purchase of
Fund shares. Sales of shares to such plans must be made in connection with a
payroll deduction system of plan funding or other system acceptable to Selig-
man Data Corp.     
   
  Section 403(b) plans sponsored by public educational institutions are not
eligible for net asset value purchases based on the aggregate investment made
by the plan or number of eligible employees. Participants in such plans are
eligible for reduced sales loads based solely on their individual investments.
    
   
  CLASS B SHARES. Class B shares are sold without an initial sales load but
are subject to a CDSL if the shares are redeemed within six years of purchase

  Class B shares are also subject to an annual distribution fee of up to .75%
and an annual service fee of up to .25% of the average daily net asset value of
the Class B shares. SFSI will make a 4% payment to dealers in respect of pur-
chases of Class B shares. Approximately eight years after purchase, Class B
shares will convert automatically into Class A shares of the Fund, which are
subject to an annual service fee of .25% but no distribution fee. Shares pur-
chased through reinvestment of dividends and distribution on Class B shares
also will convert automatically to Class A shares along with the underlying
shares on which they were earned.     
   
  Conversion occurs at the end of the month which precedes the eighth anniver-
sary of the purchase date. If Class B shares of the Fund are exchanged for
Class B shares of another Seligman Mutual Fund, the conversion period applica-
ble to the Class B shares acquired in the exchange will apply, and the holding
period of the shares exchanged will be tacked onto the holding period of the
shares acquired. Class B shareholders of the Fund exercising the exchange priv-
ilege will continue to be subject to the Fund's CDSL schedule if such schedule
is higher or longer than the CDSL schedule relating to the new Class B shares.
In addition, Class B shares of the Fund acquired by through the exchange will
be subject to the Fund's CDSL schedule if such schedule is higher or longer
than the CDSL schedule relating to the Class B shares of the fund from which
the exchange has been made.     
   
  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 distribu-
tion fee of up to .75% and an annual service fee of up to .25%, 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. Unlike Class B shares, Class D
shares do not automatically convert to Class A shares after eight years.     
   
  CONTINGENT DEFERRED SALES LOAD. A CDSL will be imposed on any redemption of
Class B or Class D shares which were purchased during the preceding six years
(for Class B shares) or twelve months (for Class D shares); however, no CDSL
will be imposed on shares acquired through the investment of dividends or dis-
tributions from any Class B or Class D shares of mutual funds within the Selig-
man Group. The amount of any CDSL will initially be used by SFSI to defray the
expense of the payment of 4% (in the case of Class B shares) or 1% (in the case
of Class D shares, made by it to Service Organization (as defined under "Admin-
istration, Shareholder Services And Distribution Plan") at the time of sale.
    
   
  To minimize the application of a CDSL to a redemption, shares acquired pursu-
ant to the investment of dividends and distributions (which are not subject to
a CDSL) will be redeemed first; followed by shares purchased at least six years
prior to redemption (in the case of Class B shares) or one year prior to re-
demption (in the case of Class D shares). Shares held for the longest period of
time within the applicable period will then be redeemed. Additionally, for
those shares determined to be subject to a CDSL, the CDSL will be assessed on
the current net asset value or original purchase price, whichever is less.     
   
  For example, assume an investor purchased 100 Class D shares in January at a
price of $10.00 per share. During the first year, 5 additional Class D shares
were acquired through investment of dividends and distributions. In January of
the following year, an additional 50 Class D 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 Class D shares with a total
value of

$1,898.75 ($12.25 per share). The CDSL for this transaction would be calculated
as follows:

  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 section 403 (b)(7) of the Code or an
individual 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
Directors 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; and (f) in connection with the redemption of Class B or Class D
shares of the Fund if the Fund is combined with another mutual fund in the Se-
ligman Group, or another similar reorganization transaction.     
   
  If, with respect to a redemption of any Class B or 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 payment or a portion of the payment made by SFSI at the time of
sale of 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 mutual
funds managed by the Manager during a specified period of time. Such bonus or
other incentive may take the form of payment for travel expenses, including
lodging, incurred in connection with trips taken by qualifying registered rep-
resentatives 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 with telephone transaction privileges, AND THE SHAREHOLDER'S
BROKER/DEALER REPRESENTATIVE, will have the ability to effect the following
transactions via telephone: (i) redemption of Fund shares, (ii) exchange of
Fund shares for shares of the same class of another Seligman Mutual Fund, (iii)
change of a dividend and/or capital gain distribution option, and (iv) change
of address. All telephone transactions are effected through Seligman Data Corp.
at (800) 221-2450.     
   
  For investors who purchase shares by completing and submitting an Account Ap-
plication (except those accounts registered as trusts (unless the trustee and
sole beneficiary are the same person), corporations or group retirement plans):
Unless an election is made otherwise on the Account Application, a shareholder
and the shareholder's broker-dealer of record, as designated on the Account Ap-
plication, will automatically receive telephone services.     
   
  For Investors who purchase shares through a broker/dealer: Telephone services
for a shareholder and the shareholder's representative may be elected by com-
pleting a supplemental election application available from the broker/dealer of
record.     
   
  For accounts registered as IRAs: Telephone services will include only ex-
changes or address changes.     
   
  For accounts registered as trusts unless the trustee and sole beneficiary are
the same person), corporations or group retirement plans: Telephone redemptions
are not permitted. Additionally group retirement plans are not permitted to
change a dividend or gain distribution option.     
   
  All Seligman Mutual Fund accounts with the same account number (i.e., regis-
tered exactly the same) as an existing account, including any new Seligman Mu-
tual Fund in which the shareholder invests in the future, will automatically
include telephone services if the existing account has telephone services. Tel-
ephone services may also be elected at any time on a supplemental election ap-
plication.     
   
  For accounts registered jointly (such as joint tenancies, tenants in common
and community property registrations), each owner, by accepting or requesting
telephone transaction services, authorizes each of the other owners to effect
telephone transactions on his or her behalf.     
   
  During times of drastic economic or market changes, a shareholder or the
shareholder's representative may experience difficulty in contacting Seligman
Data Corp. to request a redemption or exchange of Fund shares via telephone. In
these circumstances, the shareholder or the shareholder's representative should
consider using other redemption or exchange procedures. (See "Redemption Of
Shares" below.) Use of these other redemption or exchange procedures will re-
sult in the request being processed at a later time than if a telephone trans-
action 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. In any instance where the Fund or
Seligman Data Corp. is not reasonably satisfied that instructions received by
telephone are genuine, the requested transaction will not be executed, and nei-
ther they nor any of their affiliates will be liable     
 
                                       16
<PAGE>
 
   
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 un-
authorized or fraudulent instructions. Telephone transactions must be effected
through a representative of Seligman Data Corp., i.e., requests may not be com-
municated via Seligman Data Corp.'s automated telephone answering system.
Shareholders, of course, may refuse or cancel telephone services. Telephone
services may be terminated by a shareholder at any time by sending a written
request to Seligman Data Corp. TELEPHONE SERVICES MAY NOT BE ESTABLISHED BY A
SHAREHOLDER'S BROKER/DEALER WITHOUT THE WRITTEN AUTHORIZATION OF THE SHAREHOLD-
ER. Written acknowledgment of termination of telephone services will be sent to
the shareholder at the address of record.     
 
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, NY 10017. The redemption re-
quest 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 surrendering
certificates in proper form to the same address. Certificates should be sent by
registered mail. Share certificates must be endorsed for transfer or accompa-
nied by an endorsed stock power signed by all share owners exactly as their
name(s) appear(s) on the account registration. The shareholder's letter of in-
struction or endorsed stock power should specify the Fund name, account number,
class of shares (A, B or D) and the number of shares or dollar amount to be re-
deemed. The Fund cannot accept conditional redemption requests. If the redemp-
tion 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 signature(s)
of the shareholder(s) must be guaranteed by an eligible financial institution
including, but not limited to, the following: banks, trust companies, credit
unions, securities brokers and dealers, savings and loan associations and par-
ticipants in the Securities Transfer Association Medallion Program (STAMP), the
Stock Exchanges Medallion Program (SEMP) or the New York Stock Exchange Medal-
lion 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 ac-
cepting such guarantee. A signature guarantee is also necessary in order to
change the account registration. Notarization by a notary public is not an ac-
ceptable 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 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 B shares redeemed af-
ter six years and Class D shares redeemed after one year, a shareholder will
receive the net asset value per share next determined after receipt of a re-
quest in good order. If Class B shares are redeemed within six years of pur-
chase a shareholder will receive the net asset value per share next determined
after receipt of a request in good order less the applicable CDSL, as described
under "Purchase of Shares--Class B Shares" above. If Class D shares are re-
deemed 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 (less any applicable CDSL). The Fund makes no charge for
this transaction, but the dealer may charge you a service fee. "Sell" or repur-
chase orders received from an au

thorized dealer before the close of the NYSE and received by SFSI, the repur-
chase 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, less any applicable CDSL. 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 trading day. Shares held in a "street name" ac-
count 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 once per day, up to $50,000 per account. Telephone redemption requests
received by Seligman Data Corp. at (800) 221-2450 between 8:30 a.m. and 4:00
p.m. Eastern time, on any business day 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 and the circumstances under
which a shareholder may bear the risk of loss for a fraudulent transaction,
see "Telephone Transactions" above.     
       
   
  GENERAL. With respect to shares redeemed, a check for the proceeds will be
sent to the shareholder's address of record within seven calendar days after
acceptance of the redemption order and will be made payable to all of the reg-
istered owners on the Account. With respect to shares purchased by the Fund, a
check for the proceeds will be sent to the investment dealer within seven cal-
endar days after acceptance of the repurchase order and will be made payable
to the investment dealer. The Fund will not permit redemptions of shares pur-
chased by check (un less certified) until Seligman Data Corp. receives no     
tice 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 re-
purchase 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 would be
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 to reinvest them, or to shift the investment to one of the other Se-
ligman Mutual Funds, the shareholder may, within 120 calendar days of the date
of redemption, use all or any part of the proceeds of the redemption to rein-
state, 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 Seligman Group. If a
shareholder redeems Class B or 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 Seligman Mutual Funds within 120 cal-
endar 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 estab-
lished as of the close of the NYSE on the day the request is received. Selig-
man Data Corp. must be informed that the purchase represents a reinstated in-
vestment. 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, Class B and Class D
shares. Payments under the Plan may include, but are not limited to: (i) com-
pensation to securities dealers and other organizations ("Service
Organizations") for providing distribution assistance with respect to assets
invested in the Fund, (ii) compensation to Service Organizations for providing
administration, accounting and other shareholder services with respect to Fund
shareholders, and (iii) otherwise promoting the sale of shares of the Fund, in-
cluding paying for the preparation of advertising and sales literature and the
printing and distribution of such promotional materials and prospectuses to
prospective investors and defraying SFSI's costs incurred in connection with
its marketing efforts with respect to shares of the Fund. The Manager, in its
sole discretion, 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 personal service and/or the
maintenance of shareholder accounts. The fee payable 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, 1995 in respect of the Fund's Class A shares pursuant to the Plan was equal
to .24% of the Class A shares' average daily net assets.     
   
  Under the Plan, the Fund reimburses SFSI for its expenses with respect to
Class B and Class D shares at an annual rate of up to 1% of the respective av-
erage daily net asset value of the Class B and Class D shares. Proceeds from
the Class B and Class D distribution fees are used primarily to compensate
Service Organizations for administration, shareholder 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 B and 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 de-
fray the expense of the payment of 4% (in the case of Class B shares) or 1% (in
the case of Class D shares) made by it to Service Organizations at the time of
the sale. The amounts expended by SFSI in any one year upon the initial pur-
chase of Class B and Class D shares may exceed the amounts received by it from
Plan payments retained. Expenses of administration, shareholder services and
distribution of Class B and Class D shares in one fiscal year of the Fund may
be paid from Class B and Class D Plan fees, respectively, received from the
Fund in any other fiscal year.     
   
  The Plan as it relates to Class B shares was approved by the Directors of the
Fund on March 21, 1996. 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 total
amount paid for the year ended December 31, 1995 by the Fund's Class D shares
pursuant to the Plan was 1% per annum of the average daily net assets of Class
D shares. The Plan is reviewed by the Directors annually.     
 
  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, including all such shareholder accounts established after April 1,
1995 and receives compensation for providing personal service and account main-
tenance to such accounts of record.     
 
EXCHANGE PRIVILEGE
   
  A shareholder of the Fund may, without charge, exchange at net asset value
any part or all of an investment in the Fund for shares of any of the other mu-
tual funds in the Seligman Group. Exchanges may be made by mail, or by tele-
phone if the shareholder has telephone services.     
   
  Class A, Class B or Class D shares may be exchanged only for Class A, Class B
or Class D shares, respectively, of another Seligman Mutual Fund on the basis
of relative net asset value.     
   
  If Class B or Class D shares that are subject to a CDSL are exchanged for
Class B or Class D shares, respectively, of another Seligman Mutual Fund, then
for purposes of assessing the CDSL payable upon disposition of the exchanged
Class B or Class D shares, the applicable holding period shall be reduced by
the holding period of the original Class B or Class D shares.     
   
  Class B Shareholders of the Fund exercising the exchange privilege will con-
tinue to be subject to the Fund's CDSL schedule if such schedule is higher or
longer than the CDSL of the new Class B shares. In addition, Class B shares of
the Fund acquired by exchange will be subject to the Fund's CDSL schedule if
such schedule is higher or longer than the CDSL schedule relating to the Class
B shares of the Fund from which such shares were exchanged.     
   
  The Seligman Mutual Funds available under the Exchange Privilege are:     
   
  . SELIGMAN CAPITAL FUND, INC. seeks aggressive capital appreciation. Current
income is not an objective.     
   
  . SELIGMAN CASH MANAGEMENT FUND, INC. invests in high quality money market
instruments. Shares are sold at net asset value.     
   
  . SELIGMAN COMMON STOCK FUND, INC. seeks favorable current income and long-
term growth of both income and capital value without exposing capital to undue
risk.     
       
   
  . SELIGMAN FRONTIER FUND, INC. seeks to produce growth in capital value; in-
come may be considered but will only be incidental to the Fund's investment ob-
jective.

ries and the North Carolina Tax-Exempt Series, each of which invests in tax-ex-
empt securities of its designated state. (Does not currently offer Class B
shares.)     
   
  All permitted exchanges will be based on the net asset values of the respec-
tive funds determined at the close of the NYSE on that day. Telephone requests
for exchanges received between 8:30 a.m. and 4:00 p.m. Eastern time, on any
business day, by Seligman Data Corp. at (800) 221-2450, will be processed as of
the close of business 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 investment 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, as will telephone services. 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 exchange of a specific number of shares, an exchange of
shares equal to a specific dollar amount or an exchange of all shares held.
Shares for which certificates have been issued may not be exchanged via tele-
phone and may be exchanged only upon receipt of a written exchange request to-
gether with certificates representing shares to be exchanged in form for trans-
fer.     
   
  The Exchange Privilege via mail is generally applicable to investments in
group retirement plans, although some restrictions may apply. The terms of the
exchange offer described herein may be modified at any time; and not all of the
mutual funds in the Seligman Group are available to residents of all states.
Before making any exchange a shareholder should contact an authorized invest-
ment dealer or Seligman Data Corp. to obtain prospectuses of any of the Selig-
man Mutual Funds.     
   
  A broker/dealer representative of record will be able to effect exchanges on
behalf of a shareholder only if the shareholder has telephone services or if
the broker/dealer has entered into a Telephone Exchange Agreement with SFSI
wherein the broker/dealer must agree to indemnify SFSI and Seligman Mutual
Funds from any loss or liability incurred as a result of the acceptance of tel-
ephone 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 any telephone exchange request. Any rejected telephone exchange order
may be processed by mail. For more information about telephone exchange privi-
leges, which unless objected to, are assigned to most shareholders automatical-
ly, 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. Cash dividends
and gain distributions are paid by check. If the payment option you prefer is
not listed, contact Seligman Data Corp. at (800) 221-2450 to request informa-
tion on other available options. 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. Dividends and gain distributions
paid in shares are invested on the payable date using the net asset value of
the ex-dividend date. Shareholders may elect to change their dividend and gain
distribution options by writing Seligman Data Corp. at the address listed be-
low. If the shareholder has elected telephone services, changes may also be
telephoned to Seligman Data Corp. between 8:30 a.m. and 6:00 p.m. Eastern time,
by either the shareholder or the broker/dealer of record on the account. For
information about electing telephone services, see "Telephone Transactions."
These elections must be received by Seligman Data Corp. before the record date
for the dividend or distribution in order to be effective for such dividend or
distribution.     
   
  The per share dividends from net investment income on Class B and 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 B and Class D
shares. Per share dividends of the three 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, Class B and Class D shares. See "Purchase
Of Shares--Valuation."     
   
  Shareholders exchanging shares of one mutual fund for shares of another mu-
tual 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 Code. For each year so qualified, the Fund will not be subject to Fed-
eral income taxes on its net investment income and capital gains, if any, real-
ized during any taxable year, which it distributes to its shareholders, pro-
vided 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 exchanged within 90 days after acquisition will be added to the share-
holder's tax basis in the shares acquired pursuant to the Exchange or Rein-
statement 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
 
                                       23
<PAGE>
 
DISTRIBUTIONS AND OTHER REPORTABLE PAYMENTS TO THE SHAREHOLDER. THE RATE OF
BACKUP WITHHOLDING IS 31%. SHAREHOLDERS SHOULD BE AWARE THAT, UNDER REGULATIONS
PROMULGATED BY THE INTERNAL REVENUE SERVICE, THE FUND MAY BE FINED $50 ANNUALLY
FOR EACH ACCOUNT FOR WHICH A CERTIFIED TAXPAYER IDENTIFICATION NUMBER IS NOT
PROVIDED. IN THE EVENT THAT SUCH A FINE IS IMPOSED, THE FUND MAY CHARGE A SERV-
ICE FEE OF UP TO $50 THAT MAY BE DEDUCTED FROM THE SHAREHOLDER'S ACCOUNT AND
OFFSET AGAINST ANY UNDISTRIBUTED DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS. THE
FUND ALSO RESERVES THE RIGHT TO CLOSE ANY ACCOUNT WHICH DOES NOT HAVE A CERTI-
FIED TAXPAYER IDENTIFICATION NUMBER.

  ACCOUNT SERVICES. Shareholders are sent confirmation of financial transac-
tions in their Account.
 
  Other investor services are available. These include:
   
  . INVEST-A-CHECK (R) SERVICE enables a shareholder to authorize additional
purchases of Fund shares automatically by electronic funds transfer from the
shareholder's savings or checking account, if the bank that maintains the ac-
count is a member of the Automated Clearing House ("ACH"), or by preauthorized
checks to be drawn on the shareholder's checking account at regular monthly in-
tervals in fixed amounts of $200 or more, or regular quarterly intervals in
fixed amounts of $500 or more, to purchase shares. Accounts may be established
concurrently with the Invest-A-Check (R) Service only if accompanied by a $200
minimum in conjunction with the monthly investment option, or a $500 minimum in
conjunction with the quarterly investment option. See "Terms and Conditions" on
page 27.)     
 
  . AUTOMATIC DOLLAR-COST-AVERAGING SERVICE permits a shareholder of Seligman
Cash Management Fund to exchange a specified amount, at regular monthly inter-
vals in fixed amounts of $100 or more per fund, or regular quarterly intervals
in fixed amounts of $250 or more per fund, from shares of any class of the Se-
ligman Cash Management Fund into shares of the same class of any other Seligman
Mutual Fund registered in the same name. The shareholder's Cash Management Fund
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-
 
                                       24

tional shares of the Fund. (Dividend checks must meet or exceed the required
minimum purchase amount and include the shareholder's name, account number, the
name of the Fund and the class of shares in which the investment is to be
made.)     
   
  . AUTOMATIC CD TRANSFER SERVICE permits a shareholder to instruct a bank to
invest the proceeds of a maturing bank certificate of deposit ("CD") in shares
of any designated Seligman Mutual Fund. Shareholders who wish to use this serv-
ice should contact Seligman Data Corp. or a broker to obtain the necessary doc-
umentation. Banks may charge a penalty on CD assets withdrawn prior to maturi-
ty. Accordingly, it will not normally be advisable to liquidate a CD before its
maturity.     
   
  . AUTOMATIC CASH WITHDRAWAL SERVICE permits payments at regular intervals to
be made to a shareholder who owns or purchases shares worth $5,000 or more held
as book credits. Holders of Class B shares may elect to use this service imme-
diately, although certain withdrawals may be subject to a CDSL. Please contact
Seligman Data Corp. at (800) 221-2450 for more information. Holders of Class D
shares may elect to use this service with respect to shares that have been held
for at least one year. (See "Terms and Conditions" on page 27.)     
   
  . DIRECTED DIVIDENDS allows a shareholder to pay dividends to another person
or to direct the payment of such dividends to another Seligman Mutual Fund for
purchase at net asset value. Dividends on Class A, Class B and Class D shares
may only be directed to shares of the same class of another Seligman Mutual
Fund.     
   
  . OVERNIGHT DELIVERY to service shareholder requests is available for a
$15.00 fee which may be deducted from a shareholder's account, if requested.
       
  . COPIES OF ACCOUNT STATEMENTS will be sent to each shareholder free of
charge for the current year and most recent prior year. Copies of year-end
statements for prior years back to 1982 are available for a fee of $10.00 per
year, per account, with a maximum charge of $150 per account. Statement re-
quests should be forwarded, along with a check, to Seligman Data Corp.

plication has not been received as an ordinary taxable account.     
   
  For more information, write Retirement Plan Services, Seligman Data Corp.,
100 Park Avenue, New York, NY 10017 or telephone toll-free (800) 445-1777 from

thorized dealer.     
 
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, Class B and
Class D shares. THESE FIGURES ARE BASED ON HISTORICAL EARNINGS AND ARE NOT IN-
TENDED TO INDICATE FUTURE PERFORMANCE. The "total return" shows what an invest-
ment in shares of Class A, Class B or     
 
                                       25
<PAGE>
 
   
Class D of the Fund would have earned over a specified period of time (for ex-
ample, one, five and ten year periods or since inception) assuming the payment
of the maximum sales load, if any (or CDSL, upon redemption, if applicable),
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 "av-
erage 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 pe-
riod (one, five and ten year periods or since inception); i.e., the average an-
nual 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 serv-
ices and distribution fee, which if reflected would reduce the performance
quoted. The total return and average annual total return quoted from time to
time for Class A and Class D shares for periods prior to February 8, 1996 do
not reflect the increase in the management fee payable by the Fund effective on
such date, which if reflected would reduce the performance quoted. Total return
and average 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, Class B and Class D shares, the Lipper analysis assumes
investment of all dividends and distributions paid but does not take into ac-
count applicable sales loads. The Fund may also refer in advertisements or in
other promotional material to articles, comments listings and columns in the
financial press pertaining to the Fund's performance. Examples of such finan-
cial and other press publications include Barron's, Business Week,
CDA/Weisenberger Mutual Funds Investment Report, Christian Science Monitor, Fi-
nancial Planning, Financial Times, Financial World, Forbes, Fortune, Individual
Investor, Investment Advisor, Investors Business Daily, Kiplinger's, Los Ange-
les 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 1,000,000,000 shares of common stock, each with a par value of $0.10,
divided into three classes. Each share of the Fund's Class A, Class B and
Class D common stock is equal as to earnings, assets and voting privileges, ex-
cept that each class bears its own separate distribution and, potentially, cer-
tain other class expenses and has exclusive voting rights with respect to any
matter to which a separate vote of any class is required by the 1940 Act or
Maryland law. The Fund has adopted a Plan (the "Multiclass Plan") pursuant to
Rule 18f-3 under the 1940 Act permitting the issuance and sale of multiple
classes of common stock. In accordance with the Articles of Incorporation, the
Board of Directors may authorize the creation of additional classes of common
stock with such characteristics as are permitted by the Multiclass Plan and
Rule 18f-3. The 1940 Act requires that where more than one class exists, each
class must be preferred over all other classes in respect of assets specifi-
cally allocated to such class. Shares have non-cumulative voting rights, do not
have preemptive or subscription 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. These option changes must be received by Seligman Data Corp.
before the record date for the dividend or distribution in order to be effec-
tive 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. The electronic funds transfer ("ACH debit") or preauthorized check in
the amount specified will be drawn automatically on the shareholder's bank on
the fifth day (unless otherwise specified) of each month (or on the prior
business day if such day of the month falls on a weekend or holiday) in which
an investment 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 regu-
larly scheduled investments. If an ACH debit or preauthorized check is not
honored by the shareholder's bank, or if the value of shares held falls below
the required minimum, the Invest-A-Check(R) Service may be suspended. In the
event that a check or ACH debit is returned as uncollectable, Seligman Data
Corp. will cancel the purchase, redeem shares held in the shareholder's ac-
count 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
deducted to the shareholder's account. The Invest-A-Check(R) Service may be
reinstated upon written request indicating that the cause of interruption has
been corrected. The Invest-A-Check(R) Service may be terminated by the share-
holder 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 re-
sult from acts done in good faith and pursuant to these terms. Instructions
for establishing Invest-A-Check(R) Service are given on the Account Applica-
tion. In the event a shareholder exchanges all of the shares from one mutual
fund in the Seligman Group to another, the Invest-A-Check(R) Service will be
terminated in the Seligman Mutual Fund that has closed as a result of the ex-
change of all shares and the shareholder must re-apply for the Invest-A-
Check(R) Service in the Seligman Mutual Fund into which the exchange was made.
In the event of a partial exchange, the Invest-A-Check(R) Service will be con-
tinued, subject to the above conditions, in the Seligman Mutual Fund from
which the exchange was made. Accounts established in conjunction with the In-
vest-A-Check(R) Service must be accompanied by a minimum initial investment of
at least $200 in connection with the monthly investment option or $500 in con-
nection with the quarterly investment option. If a shareholder uses the In-
vest-A-Check(R) Service to make an IRA investment, the purchase will be cred-
ited 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, to
Class B 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 pay-
ment. 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 specified falls on a weekend or holiday), less, in the
case of Class B shares, any applicable CDSL. A shareholder may change the
amount of scheduled payments or may suspend payments by written notice to Se-
ligman Data Corp. at least ten days prior to the effective date of such a
change or suspension. 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 considered terminated in the event a withdrawal of shares, other than to
make scheduled 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 purchases of shares of this or any other investment company, will be dis-
advantageous 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 toward com-
pletion of a Letter of Intent the total asset value of shares of the Seligman
Mutual Funds on which a front-end sales load was paid as of the date 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 re-
quested 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, Inc. sufficient
escrowed shares will be redeemed for payment of the additional sales load.
Shares remaining in escrow after this payment will be released to the account.
The intended 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 al-
ready made under the original Agreement, will be refunded to the Fund and that
the required additional escrowed shares will be purchased by the shareholder.
       
  Shares of Seligman Cash Management Fund which have been acquired by an ex-
change of shares of another Seligman Mutual Fund on which there is a front-end
sales load may be taken into account in completing a Letter of Intent, or for
Rights of Accumulation. However, shares of the Seligman Cash Management Fund
which have been purchased directly may not be used for purposes of determining
reduced sales loads on additional purchases of the other mutual funds in the
Seligman Group.     
                                                                         
                                                                      4/96

          This Statement of Additional Information expands upon and supplements
the information contained in the current Prospectus of Seligman Communications
and Information Fund, Inc., (the "Fund") dated April 22,1996.  It should be read
in conjunction with the Prospectus, which may be obtained by writing or calling
the Fund at the above address or telephone numbers.  This Statement of
Additional Information, although not in itself a Prospectus, is incorporated by
reference into the Prospectus in its entirety.      
    
          The Fund offers three classes of shares.  Class A shares may be
purchased at net asset value plus a sales load of up to 4.75%.  Class B shares
may be purchased at net asset value and are subject to a contingent deferred
sales load ("CDSL"), if applicable, in the following amount (as a percentage of
the current net asset value or the original purchase price, whichever is less,
if redemption occurs within the indicated number of years of purchase of such
shares:  5% (less than 1 year), 4% (1 but less than 2 years), 3% (2 but less
than 4 years), 2% (4 but less than 5 years), 1% (5 but less than 6 years) and 0%
(6 or more years).  Class B shares automatically convert to Class A shares after
approximately eight years resulting in lower ongoing fees.  Shares purchased
through reinvestment of dividends and distributions on Class B shares also will
convert automatically to Class A shares along with the underlying shares on
which they were earned.   Class D shares may be purchased at net asset value and
are subject to a CDSL of 1% (of the current net asset value or the original
purchase price, whichever is less) if redeemed within one year of purchase.     
    
          Each Class A, Class B 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 B and Class D shares bear a
higher distribution fee that generally will cause the Class B and 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, Class B 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 three classes also have different exchange
privileges.

                   INVESTMENT OBJECTIVE, POLICIES AND RISKS      
      
     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 15% of its net assets in illiquid
securities including restricted securities.     
    
     The following information regarding the Fund's investment policies
supplements the information contained in the Prospectus.     

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 1995, 1994
and 1993.     

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

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

                                      -2-
<PAGE>
 
    
     Purchasing Put Options on Securities.  The Fund may purchase put options to
protect its portfolio holdings in an underlying security against a decline in
market value.  This hedge protection is provided during the life of the put
option since the Fund, as holder of the put option, can sell the underlying
security at the put exercise price regardless of any decline in the underlying
security's market price.  In order for a put option to be profitable, the market
price of the underlying security must decline sufficiently below the exercise
price to cover the premium and transaction costs.  By using put options in this
manner, the Fund will reduce any profit it might otherwise have realized in the
underlying security by the premium paid for the put option and by transaction
costs.      
    
     Because a purchased put option gives the purchaser a right and not an
obligation, the purchaser is not required to exercise the option.  If the
underlying position incurs a gain, the Fund would let the option expire
resulting in a reduced profit on the underlying security equal to the cost of
the put option.  The cost of the put option is limited to the premium plus
commission paid.  The Fund's maximum financial exposure will be limited to these
costs.      
    
     The Fund's ability to engage in option transactions may be limited by tax
considerations.      

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 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
rates were 65.77% in 1995 and 104.08% in 1994.      

                                 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 the extent necessary to effect permitted
   borrowings of up to 15% of its total assets on a secured basis;      

 .  Purchase securities on "margin," or sell "short";

 .  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;

                                      -3-
<PAGE>
 
 .  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" 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.

                                 MANAGEMENT AND EXPENSES
         
     Under the Management Agreement, dated December 29, 1988, as amended
February 8, 1996, subject to the control of the Board of Directors, J. & W.
Seligman & Co. Incorporated, (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. Effective February 8, 1996, the management fee is
equal to .90% of the Fund's average daily net assets on the first $3 billion of
net assets, .85% of the Fund's average daily net assets on the next $3 billion
of net assets and .75% of the Fund's average daily net assets in excess of $6
billion. For the years ended December 31, 1995, 1994 and 1993,the Fund paid .75%
per annum of its average daily net assets or $14,159,819, $1,547,256 and
$529,841, respectively.      
         
     The Fund pays all its expenses other than those assumed by the Manager, or
the Subadviser 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
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.      
         
         
     The Management Agreement was initially approved by the Board of Directors
on September 30, 1988 and by the shareholders at a special meeting held on
December 16, 1988 The amendments to the Management Agreement effective February
8, 1996 to increase the fee rate payable to the Manager by the Fund, were
approved by the Board of Directors on September 21, 1995 and by the shareholders
at a special meeting on February 7, 1996. The Management Agreement will continue
in effect until December 31 of each year if (1) such continuance is approved in
the manner required by 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. 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.

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, and for the year
ended December 31, 1995, 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 $19 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
"Ethics Code").  The Ethics 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 Ethics Code.  The Ethics
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 secondary
public offering.  The Ethics 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 Ethics 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

         
     The Fund has adopted an Administration, Shareholder Services and
Distribution Plan for each Class (the "Plan") in accordance with Section 12(b)
of the 1940 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 1940 Act) of the Fund and who have no direct or indirect
financial interest in the operation of the Plan or in any agreement related to
the 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 B shares on March 21, 1996 by the Board of
Directors of the Fund, including a majority of the Qualified Directors, and
became effective in respect of the Class B shares on April 22, 1996. The Plan
was approved in respect of the Class D shares on March 18, 1993 by the     

                                      -9-
<PAGE>
 
    
Board of Directors of the Fund, including a majority of the Qualified Directors,
and became effective in respect of 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 annually 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. If the amount payable in respect of Class A shares under the Plan is
proposed to be increased materially, the Fund will either (i) permit holders of
Class B shares to vote as a separate class on the proposed increase or (ii)
establish a new class of shares subject to the same payment under the Plan as
existing Class A shares, in which case the Class B shares will thereafter
convert into the new class instead of into Class A shares. No material amendment
to the 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.

    5.4% of the total dollar amount of all commission transactions in 1993.  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.

                    PURCHASE AND REDEMPTION OF FUND SHARES
         
     The Fund issues three classes of shares: Class A shares may be purchased at
a price equal to the next determined net asset value per share, plus a sales
load. Class B shares may be purchased at a price equal to the next determined
net asset value without an initial sales load, but a CDSL may be charged on
redemptions within 6 years of purchase. Class D shares may be purchased at a
price equal to the next determined net asset value without an initial sales
load, but a CDSL may be charged on redemptions within one year of purchase. See
"Alternative Distribution System," "Purchase Of Shares," and "Redemption Of
Shares" in the Prospectus.     

SPECIMEN PRICE MAKE-UP
         
     Under the current distribution arrangements between the Fund and the
Distributor, Class A shares are sold at a maximum sales charge of 4.75% and
Class B and Class D shares are sold at net asset value*.  Using the Fund's net
asset value at December 31, 1995, the maximum offering price of the Fund's
shares is as follows:

* Class B shares are subject to a CDSL declining from 5% in the first year after
  purchase to 0% after six years.
  Class D shares are subject to a CDSL of 1% on redemptions within one year of
  purchase.  See "Redemption Of Shares" in the Prospectus.      
    
CLASS A SHARES - Reduced Front-End Sale Loads      
    
Reductions Available.  Shares of any Seligman Mutual Fund sold with a front-end
sales load in a continuous offering will be eligible for the foregoing
reductions.      
         
     Volume Discounts are provided if the total amount being invested in Class A
shares of the Fund alone, or in any combination of shares of the other mutual
funds in the Seligman Group which are sold with a front-end 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 in Class A shares of the Fund and shares of the other mutual funds in
the Seligman Group sold with a front-end sales load with the total net asset
value of shares of those mutual funds already owned that were sold with a front-
end 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 front-end 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 front-end 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. ("SFSI") 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 front-end sales load of the other Mutual Funds in the
Seligman Group 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 front-end sales
load at the time of purchase.  Reduced sales loads also may apply to purchases
made within a 13-month      

                                     -11-

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" in the back of 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 of 1986, as amended,
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 table of sales loads in the Prospectus
applies to sales to "eligible employee benefit plans" (as defined in the
Fund's Prospectus), except that the Fund may sell shares at net asset value to
"eligible employee benefit plans," (i) which have at least $1 million invested
in the Seligman Group of Mutual Funds or (ii) of employees who have at least 50
eligible 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 SFSI.  Such sales must be made in connection
with a payroll deduction system of plan funding or other systems acceptable to
Seligman Data Corp., the Fund's shareholder service agent.  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 SFSI.      
    
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 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
("NYSE") 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 1940 Act, 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       

                                     -12-
<PAGE>
 
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 issued without a sales load to present and retired
directors, trustees, officers, employees and their spouses ( and family members
of the foregoing) of  the Funds, the other investment companies in the Seligman
Group, the Manager and other companies affiliated with the Manager.  Family
members are defined to include lineal descendants and lineal ancestors, siblings
(and their spouses and children) and any company or organization controlled by
any of the foregoing.  Such sales may also be  made to employee benefit plans
and thrift plans for such persons and to any investment advisory, custodial,
trust or other fiduciary account managed or advised by the Manger or any
affiliate.  These sales may be made for investment purposes only, and shares may
be resold only to the Fund.      
    
     Class A shares may be sold at net asset value to these persons since such
sales require less sales effort and lower sales related expenses as compared
with sales to the general public.      
    
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, or the right of redemption postponed for
more than seven days, if the orderly liquidation of portfolio securities is
prevented by the closing of, or restricted trading on the NYSE during periods of
emergency, or such other periods as ordered by the Securities and Exchange
Commission.   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
         
     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. The Fund
and SFSI are parties to a Distributing Agreement, dated January 1, 1993. As
general distributor of the Fund's Capital Stock, SFSI allows commissions 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 $7,741,414 in 1995, after allowance of $63,320,055 as
commissions to dealers; $693,835 in 1994, after allowance of $5,926,699 as
commissions to dealers; and $48,139 in 1993, after allowance of $773,862 as
commissions to dealers. No Class B shares were outstanding throughout the 3 year
period ended December 31, 1995. For the years ended December 31, 1995 and 1994,
SFSI retained CDSL charges from Class D shares amounting to $590,507 and
$34,431, respectively; and for the period May 3, 1993 to December 31, 1993, SFSI
retained CDSL charges from Class D shares amounting to $1,420.      

                                 VALUATION
         
     Net asset value per share of each class of the Fund is determined as of the
close of trading on the NYSE, (normally, 4:00 p.m. Eastern time), each day that
the NYSE is open.  The NYSE is currently closed on New Year's Day, Presidents'
Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day
and Christmas Day.    The Fund will also determine net asset value for each
class on each day in which there is a sufficient degree of trading in the Fund's
portfolio securities that the net asset value of Fund shares might be materially
affected.  Net asset value per share for a class is computed by dividing such
class' share of the value of the net assets of the Fund (i.e., the value of its
assets less liabilities) by the total number of outstanding shares of such
class.  All expenses of the Fund, including the Manager's fee, are accrued daily
and taken into account for the purpose of determining net asset value.    The
net asset value of Class B and 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 such shares.      
         
     Portfolio securities, including open short positions and options written,
are valued at the last sale price on the securities exchange or securities
market on which such securities primarily are traded. Securities 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. Other
securities not listed on an exchange or securities market, or securities in
which there were no transactions, are valued at the average of the most recent
bid and asked price, except in the case of open short positions where the asked
price is available. Any securities 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,
    

                                     -13-
<PAGE>
 
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 U.S. 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 U.S. dollars at the mean between the bid and offer prices of such
currencies against U.S. 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, 1995 were 36.57%, 35.33% and
22.42%, respectively.  These returns were computed by subtracting the maximum
sales load of 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, 1995 and since inception
through December 31, 1995 were 41.37% and 42.58%, respectively.  These returns
were computed assuming that all of the dividends and distributions paid by the
Fund's Class D shares, if any, were reinvested over the relevant time period.
It was then assumed that at the end of each period, the entire amount was
redeemed, subtracting the 1% CDSL, if applicable.  Performance information is
not provided for Class B shares because no Class B shares were outstanding prior
to April 22, 1996.      
    
     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, 1986 had a value of $7,561
on December 31, 1995, resulting in an aggregate total return of 656.13%.  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 $2,572 on December
31, 1995 resulting in an aggregate total return of 157.21%.  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.

                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

a major role in the geographical expansion and industrial development of the
United States.

investment opportunities."

TIME IS THE TEST

In an industry that has changed dramatically in recent years, it's comforting to
know that stability, tradition, and consistent professional service can still be
found in an investment management firm.

J. & W. Seligman & Co. Incorporated has been providing financial services for
more than 130 years. From its beginning, Seligman has adopted a long-term
approach to making money for its clients, by managing investment products and
services of the highest quality. Today, Seligman manages the Seligman Group of
Funds, which offers investors more than 30 fund options.


A PLACE IN HISTORY                                       ----------------
                                                                         
Established in 1864, Seligman played a major role                        
in the geographical expansion and industrial                             
development of the United States. The firm helped            [PHOTO]     
finance the westward path of the railroads and the                       
building of the Panama Canal. In the late 1800s                          
and early 1900s, the firm was instrumental in                            
financing the fledgling automobile and steel                             
industries. Seligman also participated in the                            
original underwritings for some of the nation's          ----------------
most prominent companies, including: General             JAMES, JESSE, AND
Motors, Victor Talking Machine Company, United           JOSEPH SELIGMAN
Artists Theater Circuit, and Maytag. In 1929,
Seligman introduced Tri-Continental Corporation -- which today is the nation's
largest diversified closed-end investment company.


SELIGMAN COMMUNICATIONS AND INFORMATION FUND

capital appreciation by investing primarily in the securities of companies
operating in all aspects of the communications, information, and related

FELLOW SHAREHOLDERS

     While 1995 was a strong year for your Fund, it was also a year that put
technology investors to the test. Because there is much to discuss regarding the
technology market and your Fund, we have asked your Portfolio Manager, Paul H.
Wick, to share his view of what took place in 1995 and to discuss his outlook
for the future. The discussion with Mr. Wick begins on page 4.

     The backdrop for your Fund's 1995 performance was the strength of the US
equity markets. The Standard & Poor's 500 Composite Stock Price Index (S&P 500)
and other indices such as the New York Stock Exchange Composite and the Wilshire
5000 were up 30% or more for the year.

     The equity markets did, however, teeter towards the end of the year due to
the Federal budget stalemate between the White House and Congress, which brought
on fears of higher inflation and interest rates. Nevertheless, the deadlock in
Washington did not deter the Federal Reserve Board from lowering short-term
interest rates on December 19 -- a move that quickly rejuvenated the equity
markets.

     Looking forward, the slowing economy, the budget negotiations, and the 1996
Presidential election are a few of the factors that may create somewhat more
volatile markets in the year ahead. However, we remain optimistic about your
Fund's performance and will continue to search for, and invest in, those
companies that present strong long-term investment opportunities.

     As many of you may already know, Seligman Communications and Information
Fund was reopened to purchases from new investors on January 29. When the Fund
was closed on June 30, 1995, it was determined by the Fund's Board of Directors
that such action was in the best interest of existing shareholders. Significant
amounts of money were flowing into the Fund at a time when stock prices of
technology companies were high and valuations were becoming less attractive. The
Board believes reopening the Fund is, once again, in the best interest of
existing shareholders. The technology market has fallen considerably since the
highs reached in September 1995, and market valuations for many technology
companies are more reasonable. In fact, the technology market is now selling at
a lower price-to-earnings ratio than the S&P 500.

     By opening the Fund, we are not declaring a bottom for the technology
market, nor are we predicting smooth sailing from this point forward. Although
we continue to see considerable opportunities in the technology market, we
believe that the market will remain volatile. Given this scenario, we suggest
that a prudent strategy of investing in Seligman Communications and Information
Fund is to make periodic regular investments over time, rather than attempting
to pin-point the ideal time to invest. This will allow an investor to
dollar-cost average his or her investment. Keep in mind, however, that while
dollar-cost averaging, over time, is a method of lowering the average price of
shares purchased, it does not assure a profit nor protect against a loss.

     We thank you for your continued investment in Seligman Communications and
Information Fund, and look forward to serving your investment needs in 1996 and
the years ahead.

By order of the Board of Directors,


/s/ William C. Morris

**Return figures reflect any change in price per share and assume the
  reinvestment of capital gain distributions. Return figures for Class A shares
  are calculated without (NAV) the effect of the initial 4.75% maximum sales
  charge. Class A share returns reflect the effect of the 0.25% Administration,
  Shareholder Services and Distribution Plan after January 1, 1993, only. The
  returns for periods of one year or less for Class D shares are calculated
  without and with the effect of the 1% contingent deferred sales load (CDSL),
  charged only on redemptions made within one year of the date of purchase. A
  fund that concentrates its investments in one economic sector may be subject
  to greater share price fluctuations than a more diversified fund. Past
  performance is not a guarantee of future results. The rate of return will vary
  and the principal value of an investment will fluctuate. Shares, if redeemed,
  may be worth more or less than their original cost.

                               MARKET?

                            A. The exceptional performance of Seligman

                               of the US technology industry.
              
    [PHOTO]                    Virtually every major segment of technology
                               experienced robust growth during the year: the
                               global personal computer market grew 23% to a
                               record 64 million units; wireless telephone
                               handsets and infrastructure equipment sales
                               expanded by 35%; the global semiconductor
- ----------------               industry grew 40% to a record $150 billion; and
SELIGMAN'S SMALL               the Internet was transformed from a small
COMPANY AND                    on-line community of scientists and academics
TECHNOLOGY TEAM:               into a mass-market information superhighway.
(FROM LEFT) GUS
SCACCO, CARLENE                The year was also witness to a number of
PALIA, SHANEAN                 excesses within the technology industry. 1995
AUSTIN, BRUCE                  spawned more initial public offerings (IPOs) of
ZIRMAN, (SEATED)               technology companies (195) than any year since
ARSEN MRAKOVCIC,               1983 (220). Many of these companies' stocks
PAUL WICK                      appreciated to levels two to three times the
                               valuations of more seasoned public companies
                               with similar fundamentals. Moreover, a number
                               of Internet-related companies with paltry or
                               non-existent earnings prospects were bid up to
                               irrational levels by investors wanting to
                               invest in any aspect of the "next big thing."

                               On balance, however, positive fundamentals of
                               most technology companies overshadowed such
                               excesses. Therefore, we were quite surprised at
                               the weakness in most technology stocks, and in
                               your Fund, in the last two months of 1995 and
                               into early 1996.

                            Q. WHAT HAPPENED IN THE TECHNOLOGY MARKET IN THE
                               FOURTH QUARTER OF 1995?

                            A. We believe a number of factors were responsible
                               for the fourth- quarter decline in technology
                               stock prices:

                               o  Prices for certain types of memory chips
                                  fell after having been stable for two years.
                                  Intel precipitated this decline by dumping
                                  excess chip inventory at year end.

                               o  Falling memory chip prices resulted in a
                                  major sell-off of shares of semiconductor
                                  equipment stocks, due to investor fears that
                                  a dramatic oversupply of chips could be
                                  imminent.

A TEAM APPROACH                o  Microsoft's new operating system, Windows
                                  95, is off to a slower than expected start.
SELIGMAN                          Many businesses are comparing Windows 95 to
COMMUNICATIONS AND                Windows NT, an even more advanced operating
INFORMATION FUND IS               system; other companies are postponing
MANAGED BY                        software upgrades indefinitely.
SELIGMAN'S SMALL
COMPANY AND                    o  The US cellular phone market has witnessed

                               1995, yet technology stock indices only        
                               slightly edged the S&P 500. As a result,       
                               large segments of the US technology sector     
                               are trading at unusually low valuations        
                               relative to the broader market indices. In     
                               the past, such valuations have augured         
                               favorably for subsequent returns.

                               While the US economy has weakened recently,
                               we doubt the likelihood of a recession in a
                               presidential election year. The US PC market
                               may indeed slow from previous years' growth
                               rates, but we expect other regions to pick
                               up the slack. Overseas, PC penetration in
                               businesses, and especially in homes, lags
                               well behind the US. We are heartened by the
                               current PC price war in Japan, where price
                               elasticity has led to surging sales for US
                               computer makers and parts suppliers.
                            
                               Overall, we expect the global PC market to
                               expand by 20% in units in 1996, and this
                               forecast could be conservative. Two positive
                               wild cards: 1) business adoption of Windows
                               95 or Windows NT would spur computer
                               upgrades to high powered Pentium machines,
                               and 2) growth of the Internet could
                               jump-start consumer PC demand.
                            
                               One area that is easier to predict is
                               network infrastructure spending. Networking
                               has been the fastest growing part of the
                               technology industry for the last three
                               years, and we see no signs of that changing.
                               Corporations around the world continue to
                               spend large sums to wire their global
                               offices together in computer networks with
                               ever-greater bandwidth. Consumers are buying
                               modem devices in record numbers to
                               participate in on-line services, the
                               Internet, and home banking. Your Fund has
                               numerous holdings in the communications
                               infrastructure area, and many of our
                               semiconductor investments are in key
                               suppliers to the networking industry.
                            
                            Q. ARE THERE ANY NEW DEVELOPMENTS IN THE
                               TECHNOLOGY MARKET THAT MAKE YOU OPTIMISTIC
                               GOING FORWARD?
                            
                            A. We are excited about a number of important
                               developments in the consumer electronics
                               area:
                            
                               o  The direct broadcast satellite (DBS)
                                  industry is experiencing explosive growth
                                  in the US. Transceivers and set-top
                                  converters sold with these systems are a
                                  significant new market for select US
                                  semiconductor firms.
                            
                               o  The "64-bit" video game systems slated to
                                  ship in late 1996 and early 1997
                                  represent a quantum leap in performance
                                  over older generation machines. We expect
                                  these new game machines to revive the
                                  presently moribund video game hardware
                                  and software markets. 
                            
                               o  Digital Video Disk (DVD) players expected
                                  for Christmas 1996 are likely to make the
                                  VCR obsolete. The new DVD players can 
                                  play audio CDs, video game disks, and 
                                  full-length movies on a single small disk
                                  at visual resolutions that far exceed
                                  VCRs. A number of your Fund's 
                                  semiconductor holdings are likely to win
                                  significant designs into these systems.
                            
                               o  Over the next two years, major new
                                  Personal Communication Services (PCS)
                                  networks are planned to be built all over
                                  America. The first of these wireless
                                  voice and data networks should be up and
                                  running by late 1996. As a result, we
                                  expect prices of wireless telephone
                                  service to fall significantly as existing
                                  cellular carriers react to this
                                  heightened competition. Lower service
                                  prices logically should translate into
                                  renewed growth in wireless telephones and
                                  pagers.
                            
                               o  The cable television service providers
                                  and telephone companies are in a race to
                                  offer high speed access to on-line
                                  services and the Internet. As these new
                                  service offerings roll out in 1997, we
                                  expect the power of the Internet will
                                  increase dramatically in unpredictable
                                  but exciting ways.
                            
                               In summary, we remain as enthused as ever
                               about the prospects for technology--the
                               world's fastest growing major industry. If
                               anything, the pace of change has
                               accelerated, and with it, the potential
                               opportunities.

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.

FEDERAL TAX STATUS OF 1995 GAIN DISTRIBUTION FOR TAXABLE ACCOUNTS

The distribution of $1.905 per share, consisting of $0.513 from net long-term
gain and $1.392 from net short-term gain, realized on investment transactions in
1995, was paid on December 27, 1995, 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 1995 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 $22.41 for Class A and $21.75 for Class D.

A year-end statement of account showing activity for 1995 and a combined Form
1099-DIV/B has been mailed to each shareholder. Form 1099-B 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-DIV shows
the amount of the distribution from gain on investments paid during the year.

NOTES TO FINANCIAL STATEMENTS

1. Seligman Communications and Information Fund, Inc. (the "Fund") offers two
classes of shares. All shares existing prior to May 3, 1993, were 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
distribution fee of up to 0.75% and a service fee of up to 0.25% on an annual
basis, 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 value of shares of each class. Class-specific expenses,
   which include distribution and service fees and any other items that are
   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, 1995, amounted to $2,980,047,711
and $1,185,095,516, respectively.

   At December 31, 1995, the cost of investments for federal income tax purposes
was $2,414,483,290 and the tax basis gross unrealized appreciation and
depreciation of portfolio securities amounted to $304,816,709 and $187,377,086,
respectively.


4. At December 31, 1995, the Fund owned short-term investments which matured in
less than 7 days.

5. 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.

   Effective February 8, 1996, the management fee rate is 0.90% of the first $3
billion of the Fund's average daily net assets, 0.85% of the next $3 billion of
average daily net assets and 0.75% of average daily net assets in excess of $6
billion.

   Seligman Financial Services, Inc. (the "Distributor"), agent for the
distribution of Fund shares and an affiliate of the Manager, received
concessions of $7,741,414 from sales of Class A shares, after commissions of
$63,320,055 paid to dealers.

   The Fund has 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, 1995, fees paid aggregated $3,487,717,
or 0.24% per annum of the average daily net assets of Class A shares. 

   The Fund has 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, 1995,
fees paid amounted to $4,576,736, 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, 1995,
such charges amounted to $590,507.

   Effective April 1, 1995, Seligman Services, Inc., an affiliate of the
Manager, became eligible to receive commissions from certain sales of shares of
the Fund, as well as distribution and service fees pursuant to the Plan. For the

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 amounts. 

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, 1995, the related statements of operations for the year
then ended and of changes in net assets for each of the years in the two-year
period then ended, and the financial highlights for each of the periods
presented. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits. 

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of
December 31, 1995 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, 1995, 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 SUPPLEMENTARY

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

          FIRST:  The total number of shares of capital stock of all classes
which the Corporation has authority to issue is 1,000,000,000 shares, which were
previously classified by the Board of Directors of the Corporation into two
classes designated as Class A Common Stock and Class D Common Stock.  The number
of authorized shares of Class A Common Stock and of Class D Common Stock each
consisted of the sum of x and y, where x equalled the issued and outstanding
shares of such class and y equalled 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; and, in the
event application of the formula above would have resulted, at any time, in
fractional shares, the applicable number of authorized shares of each class was
to have been rounded down to the nearest whole number of shares of such class.

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

          (a)  The Common Stock of the Corporation shall have three classes of
     shares, which shall be designated Class A Common Stock, Class B Common
     Stock and Class D Common Stock.  The number of authorized shares of Class A
     Common Stock, of Class B Common Stock and of Class D Common Stock shall
     each consist of the sum of x and y, where x equals the issued and
     outstanding shares of such class and y equals one-third of the authorized
     but unissued shares of Common Stock of all classes; provided that at all
     times the aggregate authorized, issued and outstanding shares of Class A,
     Class B and Class D Common Stock shall not exceed the authorized number of
     shares of Common Stock (i.e., 1,000,000,000 shares of Common Stock until
     changed by further action of the Board of Directors in accordance with
     Section 2-208.1 of the Maryland General Corporation Law, or any successor
     provision); and, in the event application of the formula above would
     result, at any time, in fractional shares, the applicable number of
     authorized shares of each class shall be rounded down to the nearest whole
     number of shares of such class.  Any class of Common Stock shall be
     referred to herein individually as a "Class" and collectively, together
     with any further class or classes from time to time established, as the
     "Classes".

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

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

               (2)  Class B shares may be subject to such contingent deferred
          sales charges as may be established from time to time by the Board of
          Directors in accordance with the Investment Company Act and applicable
          rules and regulations of the NASD.  Subject to subsection (5) below,
          each Class B share shall convert automatically into Class A shares on
          the last business day of the month that precedes the eighth
          anniversary of the date of issuance of such Class B share; such
          conversion shall be effected on the basis of the relative net asset
          values of Class B shares and Class A shares as determined by the
          Corporation on the date of conversion.

                                      -1-
<PAGE>
 
               (3)  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.

               (4)  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.

               (5)  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.

               (6)  As to any matter with respect to which a separate vote of
          any Class is required by the Investment Company Act or by the Maryland
          General Corporation Law (including, without limitation, approval of
          any plan, agreement or other arrangement referred to in subsection (4)
          above), such requirement as to a separate vote by the Class shall
          apply in lieu of single Class voting, and, if permitted by the
          Investment Company Act or any rules, regulations or orders 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 affect the
          interest of a particular Class, only the holders of shares of the
          affected Class shall be entitled to vote.

     THIRD: These Articles Supplementary do not change the total number of
authorized shares of the Corporation.

          IN WITNESS WHEREOF, SELIGMAN COMMUNICATIONS AND INFORMATION FUND, INC.
has caused these Articles Supplementary to be signed in its name and on its
behalf by its President and witnessed by its Secretary, and each of said
officers of the Corporation has also acknowledged these Articles Supplementary
to be the corporate act of the Corporation and has stated under penalties of
perjury that to the best of his knowledge, information and belief that the
matters and facts set forth with respect to approval are true in all material
respects, all on April 10, 1996.

                             MANAGEMENT AGREEMENT

     MANAGEMENT AGREEMENT, dated as of December 29, 1988, and amended January 1,
1996 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 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
<PAGE>
 
Manager promptly after the end of each month a fee, calculated on each day
during such month, on the basis of the Corporation's net assets at the close of
business on the previous day, equal to an annual rate of 0.90% of the
Corporation's average daily net assets on the first 3,000,000,000 of net assets,
 .85% of the Corporation's average daily net assets on the next 3,000,000,000 and
 .75% of the Corporation's average daily net assets in excess of $6,000,000,000.

     (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.

     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 31, 1996 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 31 or prior to December 31 of any year thereafter that it does not
desire such continuance. This Agreement may be terminated at any time, without
<PAGE>
 
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.

     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.

     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.

                             SUBADVISORY AGREEMENT

              SELIGMAN COMMUNICATIONS AND INFORMATION FUND, INC.


SUBADVISORY AGREEMENT, dated as of May 19, 1994 and amended January 1, 1996
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 as amended January 1, 1996 (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 
<PAGE>
 
          Subadviser each month a fee, equal to the applicable percentage of the
          average monthly Net Qualifying Assets of the Fund.

     (b)  As used herein:

          (1)  The term "Applicable Percentage" means the percentage fee rate
               that the Manager receives from the Fund pursuant to the
               Management Agreement, which equals .90% of the Fund's average
               daily net assets on the first $3,000,000,000 of net assets, .85%
               of the Fund's average daily net assets on the next $3,000,000,000
               and .75% of the Fund's average daily net assets in excess of
               $6,000,000,000.

          (2)  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 
<PAGE>
 
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, 1996, 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 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
to impose any duty upon either of the parties, to do anything in violation of
any applicable laws or regulations.


     IN WITNESS WHEREOF, the Manager and the Subadviser have caused this
Agreement to be executed by their duly authorized officers as of the date first
above written.

                           the Seligman Mutual Funds

                                    DEALER

Dear Dealer:

     Your Sales Agreement with Seligman Financial Services, Inc. ("SFSI") is
hereby amended to include the following provisions in connection with the
offering by certain of the Seligman Mutual Funds of Class B shares as described
in each applicable prospectus:


1.   Dealer agrees to comply with the attached "Policies and Procedures" with
     respect to sales of Seligman Mutual Funds offering three classes of shares.

2.   SFSI shall be entitled to a contingent deferred sales load ("CDSL") on
     redemptions within six years of purchase on any Class B shares sold and
     within one year of purchase on any Class D shares sold.  With respect to
     omnibus accounts in which Class B shares or Class D shares are held at
     Seligman Data Corp. ("SDC") in Dealer's name, Dealer agrees that by the
     tenth day of each month it will furnish to SDC a report of each redemption
     in the preceding month to which a CDSL was applicable, accompanied by a
     check payable to SFSI in payment of the CDSL due.

3.   If, with respect to a redemption of any Class B shares or Class D shares
     sold by Dealer, the CDSL is waived because the redemption qualifies for a
     waiver set forth in the Fund's prospectus, Dealer shall promptly remit to
     SFSI an amount equal to the payment made by SFSI to Dealer at the time of
     sale with respect to such Class B shares or Class D Shares.

4.   The Dealer will comply in all respects with Notice to Members 95-80 of the
     National Association of Securities Dealers, Inc. regarding members
     obligations and responsibilities regarding mutual fund sales practices.

     The sale of any Class A,Class B or Class D shares of a Seligman Mutual Fund
will constitute Dealer's acceptance of and agreement with the terms set forth
herein.

                                   EXHIBIT C

                            POLICIES AND PROCEDURES

     In connection with the offering by the Funds of three classes of shares,
one subject to a front-end sales load and a service fee ("Class A Shares"), one
subject to a service fee, a distribution fee, no front-end sales load and a
contingent deferred sales load on redemptions within six years of purchase
("Class B Shares") and one subject to a service fee, a distribution fee, no
front-end sales load and a contingent deferred sales load on redemptions within
one year of purchase ("Class D Shares"), it is important for an investor to
choose the method of purchasing shares which best suits his or her particular
circumstances. To assist investors in these decisions, Seligman Financial
Services has instituted the following policies with respect to orders for
Shares:

     1.   No purchase order may be placed for Class B Shares or Class D Shares
          for amounts of $4,000,000 or more.

     2.   Any purchase order for less than $4,000,000 may be for either Class A,
          Class B or Class D Shares in light of the relevant facts and
          circumstances, including:

          a.   the specific purchase order dollar amount;

          b.   the length of time the investor expects to hold his Shares; and

          c.   any other relevant circumstances such as the availability of
               purchases under a Letter of Intent, Volume Discount, or Right of
               Accumulation.

     There are instances when one method of purchasing Shares may be more
appropriate than another.  For example, an investor who would qualify for a
significant discount from the maximum sales load on Class A Shares may determine
that payment of such a reduced front-end sales load and service fee is
preferable to payment of higher ongoing distribution fee.  On the other hand, an
investor whose order would not qualify for such a discount may wish to have all
of his or her funds invested in Class B or Class D Shares.  An investor who
expects to hold his or her shares for longer than eight years might prefer Class
B Shares over Class D Shares because of the conversion feature; once the Class B
Shares have converted to Class A Shares, the ongoing distribution fees will be
reduced.  Class D Shares may remain a more attractive choice for shorter-term
investors because of the contingent deferred sales load on such shares is only
1%, and it does not apply if the investor owns his or her shares for at least
one year.  If an investor anticipates that he or she will redeem his or her
Class B Shares or Class D Shares while still subject to a contingent deferred
sales charge, the investor may, depending on the amount of the purchase, pay an
amount greater than the sales load and service fee attributable to Class A
Shares.

     Appropriate supervisory personnel within your organization must ensure that
all employees receiving investor inquiries about the purchase of Shares of a
Fund advise the investor of then available pricing structures offered by the
Fund, and the impact of choosing one method over another.  In some instances it
may be appropriate for a supervisory person to discuss a purchase with the
investor.

     Questions relating to this policy should be directed to Stephen J. Hodgdon,
President, Seligman Financial Services at (212) 850-1217.

     The Dealer and Seligman Financial Services, Inc. ("Seligman Financial 
Services"), as exclusive agent for distribution of Class A and Class D Shares
(as described in the "Policies and Procedures," as set forth below) of the
Capital Stock and/or Class A and Class D Shares of beneficial interest
(collectively, the "Shares") of Seligman Capital Fund, Inc., Seligman Common
Stock Fund, Inc., Seligman Communications and Information Fund, Inc., Seligman
Frontier Fund, Inc., Seligman Growth Fund, Inc., Seligman Henderson Global Fund
Series, Inc., Seligman High Income Fund Series, Seligman Income Fund, Inc.,
Seligman New Jersey Tax-Exempt Fund, Inc., Seligman Pennsylvania Tax-Exempt
Fund, Seligman Tax-Exempt Fund Series, Inc. and Seligman Tax-Exempt Series Trust
and or any other mutual fund for which Seligman Financial Services is exclusive
agent for distribution (herein called the Funds), agree as follows:

1.   The Dealer agrees to comply with the attached "Policies and Procedures"
     with respect to sales of Seligman Mutual Funds offering two classes of
     shares, as set forth below.

2.   An order for Shares of one or more of the Funds, placed by the Dealer with
     Seligman Financial Services, will be confirmed at the public offering price
     as described in each Fund's current prospectus.  Unless otherwise agreed
     when an order is placed, the Dealer shall remit the purchase price to the
     Fund, or Funds, with issuing instruction, within the period of time
     prescribed by existing regulations.  No wire orders under $1,000 may be
     placed for initial purchases.

3.   Shares of the Funds shall be offered for sale and sold by the Dealer only
     at the applicable public offering price currently in effect, determined in
     the manner prescribed in each Fund's prospectus.  Seligman Financial
     Services will make a reasonable effort to notify the Dealer of any
     redetermination or suspension of the current public offering price, but
     Seligman Financial Services shall be under no liability for failure to do
     so.

4.   On each purchase of Shares by the Dealer, the Dealer shall be entitled,
     based on the Class of Shares purchased and except as provided in each
     Fund's current prospectus, to a concession determined as a percentage of
     the price to the investor as set forth in each Fund's current prospectus.
     On each purchase of Class A Shares, Seligman Financial Services reserves
     the right to receive a minimum concession of $.75 per transaction.  No
     concessions will be paid to the Dealer for the investment of dividends in
     additional shares.

5.   Except for sales to and purchases from the Dealer's retail customers, all
     of which shall be made at the applicable current public offering price or
     the current price bid by Seligman Financial Services on behalf of the Fund,
     the Dealer agrees to buy Shares only through Seligman Financial Services
     and not from any other sources and to sell shares only to Seligman
     Financial Services, the Fund or its redemption agent and not to any other
     purchasers.

6.   By signing this Agreement, both Seligman Financial Services and the Dealer
     warrant that they are members of the National Association of Securities
     Dealers, Inc., and agree that termination of such membership at any time
     shall terminate this Agreement forthwith regardless of the provisions of
     paragraph 10 hereof.  Each party further agrees to comply with all rules
     and regulations of such Association and specifically to observe the
     following provisions:

     (a)  Neither Seligman Financial Services nor the Dealer shall withhold
          placing customers' orders for Shares so as to profit itself as a
          result of such withholding.

     (b)  Seligman Financial Services shall not purchase Shares from any of the
          Funds except for the purpose of covering purchase orders already
          received, and the Dealer shall not purchase Shares of any of the Funds
          through Seligman Financial Services other than for investment, except
          for the purpose of covering purchase orders already received.
<PAGE>
 
     (c)  Seligman Financial Services shall not accept a conditional order for
          Shares on any basis other than at a specified definite price.  The
          Dealer shall not, as principal, purchase Shares of any of the Funds
          from a recordholder at a price lower than the bid price, if any, then
          quoted by or for the Fund, but the Dealer shall not be prevented from
          selling Shares for the account of a record owner to Seligman Financial
          Services, the Fund or its redemption agent at the bid price currently
          quoted by or for such Fund, and charging the investor a fair
          commission for handling the transaction.

     (d)  If Class A Shares are repurchased by a Fund or by Seligman Financial
          Services as its agent, or are tendered for redemption within seven
          business days after confirmation by Seligman Financial  Services of
          the original purchase order of the Dealer for such Shares, (i) the
          Dealer shall forthwith refund to Seligman Financial Services the full
          concession allowed to the Dealer on the original sales and (ii)
          Seligman Financial Services shall forthwith pay to the Fund Seligman
          Financial Services' share of the "sales load" on the original sale by
          Seligman Financial Services, and shall also pay to the Fund the refund
          which Seligman Financial Services received under (i) above.  The
          Dealer shall be notified by Seligman Financial Services of such
          repurchase or redemption within ten days of the date that such
          redemption or repurchase is placed with Seligman Financial Services,
          the Fund or its authorized agent.  Termination or cancellation of this
          Agreement shall not relieve the Dealer or Seligman Financial Services
          from the requirements of this clause (d).

7.   (a)  Seligman Financial Services shall be entitled to a contingent deferred
          sales load ("CDSL") on redemptions within one year of purchase on any
          Class D Shares sold. With respect to omnibus accounts in which Class D
          Shares are held at Seligman Data Corp. ("SDC") in the Dealer's name,
          the Dealer agrees that by the tenth day of each month it will furnish
          to SDC a report of each redemption in the preceding month to which a
          CDSL was applicable, accompanied by a check payable to Seligman
          Financial Services in payment of the CDSL due.

     (b)  If, with respect to a redemption of any Class D Shares sold by the
          Dealer, the CDSL is waived because the redemption qualifies for a
          waiver set forth in the Fund's prospectus, the Dealer shall promptly
          remit to Seligman Financial Services an amount equal to the payment
          made by Seligman Financial Services to the Dealer at the time of sale
          with respect to such Class D Shares.

8.   In all transactions between Seligman Financial Services and the Dealer
     under this Agreement, the Dealer will act as principal in purchasing from
     or selling to Seligman Financial Services.  The dealer is not for any
     purposes employed or retained as or authorized to act as broker, agent or
     employee of any Fund or of Seligman Financial Services and the Dealer is
     not authorized in any manner to act for any Fund or Seligman Financial
     Services or to make any representations on behalf of Seligman Financial
     Services.  In purchasing and selling Shares of any Fund under this
     Agreement, the Dealer shall be entitled to rely only upon matters stated in
     the current offering prospectus of the applicable Fund and upon such
     written representations, if any, as may be made by Seligman Financial
     Services to the Dealer over the signature of Seligman Financial Services.

9.   Seligman Financial Services will furnish to the Dealer, without charge,
     reasonable quantities of the current offering prospectus of each Fund and
     sales material issued from time to time by Seligman Financial Services.

10.  Either Party to this Agreement may cancel this Agreement by written notice
     to the other party.  Such cancellation shall be effective at the close of
     business on the 5th day following the date on which such notice was given.
     Seligman Financial Services may modify this Agreement at any time by
     written notice to the Dealer.  Such notice shall be deemed to have been
     given on the date upon which it was either delivered personally to the
     other party or any officer or member thereof, or was mailed postage-paid,
     or delivered to a telegraph office for transmission to the other party at
     his or its address as shown herein.
<PAGE>
 
11.  This Agreement shall be construed in accordance with the laws of the State
     of New York and shall be binding upon both parties hereto when signed by
     Seligman Financial Services and by the Dealer in the spaces provided on the
     cover of this Agreement.  This Agreement shall not be applicable to Shares
     of a Fund in a state in which such Fund Shares are not qualified for sale.


                            POLICIES AND PROCEDURES

     In connection with the offering by the Funds of three classes of shares,
one subject to a front-end sales load and a service fee ("Class A Shares"), one
subject to a service fee, a distribution fee, no front-end sales load and a
contingent deferred sales load on redemptions within six years of purchase
("Class B Shares") and one subject to a service fee, a distribution fee, no
front-end sales load and a contingent deferred sales load on redemptions within
one year of purchase ("Class D Shares"), it is important for an investor to
choose the method of purchasing shares which best suits his or her particular
circumstances.  To assist investors in these decisions, Seligman Financial
Services has instituted the following policies with respect to orders for
Shares:

     1.   No purchase order may be placed for Class B Shares or Class D Shares
          for amounts of $4,000,000 or more.

     2.   Any purchase order for less than $4,000,000 may be for either Class A,
          Class B or Class D Shares in light of the relevant facts and
          circumstances, including:

          a.   the specific purchase order dollar amount;

          b.   the length of time the investor expects to hold his Shares; and

          c.   any other relevant circumstances such as the availability of
               purchases under a Letter of Intent, Volume Discount, or Right of
               Accumulation.

     There are instances when one method of purchasing Shares may be more
appropriate than another.  For example, an investor who would qualify for a
significant discount from the maximum sales load on Class A Shares may determine
that payment of such a reduced front-end sales load and service fee is
preferable to payment of higher ongoing distribution fee.  On the other hand, an
investor whose order would not qualify for such a discount may wish to have all
of his or her funds invested in Class B or Class D Shares.  An investor who
expects to hold his or her shares for longer than eight years might prefer Class
B Shares over Class D Shares because of the conversion feature; once the Class B
Shares have converted to Class A Shares, the ongoing distribution fees will be
reduced.  Class D Shares may remain a more attractive choice for shorter-term
investors because of the contingent deferred sales load on such shares is only
1%, and it does not apply if the investor owns his or her shares for at least
one year.  If an investor anticipates that he or she will redeem his or her
Class B Shares or Class D Shares while still subject to a contingent deferred
sales charge, the investor may, depending on the amount of the purchase, pay an
amount greater than the sales load and service fee attributable to Class A
Shares.

     Appropriate supervisory personnel within your organization must ensure that
all employees receiving investor inquiries about the purchase of Shares of a
Fund advise the investor of then available pricing structures offered by the
Fund, and the impact of choosing one method over another.  In some instances it
may be appropriate for a supervisory person to discuss a purchase with the
investor.

     Questions relating to this policy should be directed to Stephen J. Hodgdon,
President, Seligman Financial Services at (212) 850-1217.

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


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

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

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

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

                                       1
<PAGE>
 
          SECTION 5.  The Distributor shall provide to the Fund's Directors, and
the Directors shall review, at least quarterly, a written report of the amounts
so expended and the purposes for which such expenditures were made.

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

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

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

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

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

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

                                       2
<PAGE>
 
administration, shareholder services and distribution fees received from the
Fund in respect of Class A shares in any other fiscal year.

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

                            DISTRIBUTION AGREEMENT

ADMINISTRATION, SHAREHOLDER SERVICES AND DISTRIBUTION AGREEMENT, dated as of
____________________, 19__ between Seligman Financial Services, Inc. ("Seligman

     The Parties hereto enter into a Administration, Shareholder Services and

Fund, Inc., Seligman New Jersey Tax-Exempt Fund, Inc., Seligman Pennsylvania
Tax-Exempt Fund Series, Seligman Tax-Exempt Fund Series, Inc., Seligman Tax-

become members of the Seligman Group of Investment Companies which adopt an
Administration, Shareholder Services and Distribution Plan, pursuant to Rule
12b-1 under the Investment Company Act of 1940, as amended (the "Act"), and in
consideration of the mutual agreements herein made, agree as follows:

     The Service Organization shall make such use of or provide such information
and services as may be necessary or appropriate (i) to provide shareholder
services to shareholders of the Funds and (ii) to assist Seligman Financial
Services in any distribution of shares of the Funds, including, without
limitation, making use of the Service Organization's name, client lists, and
publications, for the solicitation of sales of shares of the Funds to Service
Organization clients, and such other assistance as Seligman Financial Services
reasonably requests, to the extent permitted by applicable statute, rule or
regulation.

1.   Except with respect to the Class D shares of a Fund for the first year
     following the sale thereof, Seligman Financial Services shall pay to the
     Service Organization a service fee (as defined in the National Association
     of Securities Dealers, Inc. Rules of Fair Practice) not to exceed .25 of 1%
     per annum of the average daily net assets of each class of shares of each
     Fund attributable to the clients of the Service Organization.

2.   With respect to the first year following the sale of Class D shares of a
     Fund, Seligman Financial Services shall pay to the Service Organization at
     or promptly after the time of sale a service fee (as defined in the
     National Association of Securities Dealers, Inc. Rules of Fair Practice)
     not to exceed .25 of 1% of the net asset value of the Class D shares sold
     by the Service Organization.  Such service fee shall be paid to the Service
     Organization solely for personal services and/or the maintenance of
     shareholder accounts to be provided by the Service Organization to the
     purchaser of such Class D Shares over the course of the first year
     following the sale.

3.   Any service fee paid hereunder shall be paid solely for personal services
     and/or the maintenance of shareholder accounts. For greater certainty, no
     part of a service fee shall be paid for subtransfer agency services,
     subaccounting services, or administrative services.
<PAGE>
 
4.   In addition to payment of the service fee, from time to time Seligman
     Financial Services may make payments to the Service Organization in
     addition to those contemplated above for providing distribution assistance
     with respect to assets invested in each Fund by its clients.

5.   Neither the Service Organization nor any of its employees or agents are
     authorized to make any representation concerning the Funds or the Funds'
     shares except those contained in the then current Prospectus, copies of
     which will be supplied by Seligman Financial Services.  The Service
     Organization shall have no authority to act as agent for Seligman Financial
     Services or the Funds.

6.   In consideration of the services provided pursuant to paragraphs 1, 2
     and/or 4 above, the Service Organization shall be entitled to receive fees
     as are set forth in Exhibit A hereto as may be amended from time to time by
     Seligman Financial Services.  Seligman Financial Services has no obligation
     to make any such payments and the Service Organization agrees to waive
     payment of its fee until Seligman Financial Services is in receipt of the
     fee from the Fund(s).  The payment of fees has been authorized pursuant to
     an Administration, Shareholder Services and Distribution Plans (the
     "Plans") approved by the Directors/Trustees and the shareholders of the
     Funds pursuant to the requirements of the Act and such authorizations may
     be withdrawn at any time.

7.   It is understood that the Funds reserve the right, at their discretion and
     without notice, to suspend or withdraw the sale of shares of the Funds.
     This Agreement shall not be construed to authorize the Service Organization
     to perform any act that Seligman Financial Services would not be permitted
     to perform under the respective Distributing Agreements between each of the
     Funds and Seligman Financial Services.

8.   Subject to the proviso in Section 6 of the Plans, this Agreement shall
     continue until December 31 of the year in which any Plan has first been
     approved by shareholders and through December 31 of each year thereafter
     provided such continuance is specifically approved at least annually by a
     vote of a majority of (i) the Fund's Directors/Trustees and (ii) the
     Qualified Directors/Trustees cast in person at a meeting called for the
     purpose of voting on such approval and provided further that the Service
     Organization shall not have notified Seligman Financial Services in writing
     at least 60 days prior to the anniversary date of the previous continuance
     that it does not desire such continuance.  This Agreement may be terminated
     at any time without payment of any penalty with respect to any of the Funds
     by vote of a majority of the Qualified Directors/Trustees, or by vote of a
     majority of the outstanding voting securities of the particular Fund or
     class or series of a Fund, on 60 days' written notice to the Service
     Organization and Seligman Financial Services.  Notwithstanding anything
     contained herein, in the event that any of the Plans shall be terminated or
     any of the Plans or any part thereof shall be found invalid or ordered
     terminated by any regulatory or judicial authority, or the Service
     Organization shall fail to perform the services contemplated by this
     Agreement, such determination to be made in good faith by Seligman
     Financial Services, this Agreement may be terminated with respect to such
     Plan effective upon receipt of written notice thereof by the Service
     Organization.  This Agreement will also terminate automatically in the
     event of its assignment.

9.   All communications to Seligman Financial Services shall be sent to it at
     its offices, 100 Park Avenue, New York, New York  10017.

     Any notice to the Service Organization shall be duly given if mailed or
     telegraphed to it at the address shown below.

10.  As used in this Agreement, the terms "assignment", "interested person" and
     "vote of a majority of the outstanding voting securities" shall have the
     respective meanings specified in the Act and in the rules and regulations
     thereunder and the term "Qualified Directors/Trustees" shall mean the
     Directors/Trustees of a Fund who are not interested persons of the Fund and
     have no direct or indirect financial interest in its Plan or in any
     agreements related to the Plan.

11.  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, any of the parties to do anything in violation of any
     applicable laws or regulations.

IN WITNESS WHEREOF, Seligman Financial Services and the Service Organization
have caused this Agreement to be executed by their duly authorized offices as of
the date first above written.

                        SELIGMAN GROUP OF MUTUAL FUNDS

              Plan for Multiple Classes of Shares (three classes)
              --------------------------------------------------


          THIS PLAN, as it may be amended from time to time, sets forth the
separate arrangement and expense allocation of each class of shares (a "Class")
of each registered open-end management investment company, or series thereof, in
the Seligman Group of Mutual Funds that offers multiple classes of shares (each,
a "Fund").  The Plan has been adopted pursuant to Rule 18f-3(d) under the
Investment Company Act of 1940, as amended (the "Act"), by a majority of the
Board of Directors or Trustees, as applicable ("Directors"), of each Fund listed
on Schedule I hereto, including a majority of the Directors who are not
interested persons of such Fund within the meaning of Section 2(a)(19) of the
Act ("Disinterested Directors").  Any material amendment to this Plan is subject
to the prior approval of the Board of Directors of each Fund to which it
relates, including a majority of the Disinterested Directors.

1.   General
     -------

     A.   Any Fund may issue more than one Class of voting stock, provided that
          each Class:

          i.   Shall have a different arrangement for shareholder services or
               the distribution of securities or both, and shall pay all of the
               expenses of that arrangement;

          ii.  May pay a different share of other expenses, not including
               advisory or custodial fees or other expenses related to the
               management of the Fund's assets, if these expenses are actually
               incurred in a different amount by that Class, or if the Class
               receives services of a different kind or to a different degree
               than other Classes of the same Fund ("Class Level Expenses");

          iii. May pay a different advisory fee to the extent that any
               difference in amount paid is the result of the application of the
               same performance fee provisions in the advisory contract of the
               Fund to the different investment performance of each Class;

          iv.  Shall have exclusive voting rights on any matter submitted to
               shareholders that relates solely to its arrangement;

                                      -1-
<PAGE>
 
          v.   Shall have separate voting rights on any matter submitted to
               shareholders in which the interests of one Class differ from the
               interests of any other Class; and

          vi.  Shall have in all other respects the same rights and obligations
               as each other Class of the Fund.

     B.   i.   Except as expressly contemplated by this paragraph B., no types
               or categories of expenses shall be designated Class Level
               Expenses.

          ii.  The Directors recognize that certain expenses arising in certain
               sorts of unusual situations are properly attributable solely to
               one Class and therefore should be borne by that Class.  These
               expenses ("Special Expenses") may include, for example: (i) the
               costs of preparing a proxy statement for, and holding, a special
               meeting of shareholders to vote on a matter affecting only one
               Class; (ii) the costs of holding a special meeting of Directors
               to consider such a matter; (iii) the costs of preparing a special
               report relating exclusively to shareholders of one Class; and
               (iv) the costs of litigation affecting one Class exclusively.  J.
               & W. Seligman & Co. Incorporated (the "Manager") shall be
               responsible for identifying expenses that are potential Special
               Expenses.

          iii. Subject to clause iv. below, any Special Expense identified by
               the Manager shall be treated as a Class Level Expense.

          iv.  Any Special Expense identified by the Manager that is material to
               the Class in respect of which it is incurred shall be submitted
               by the Manager to the Directors of the relevant Fund on a case by
               case basis with a recommendation by the Manager as to whether it
               should be treated as a Class Level Expense.  If approved by the
               Directors, such Special Expense shall be treated as a Class Level
               Expense of the affected class.

     C.   i.   Realized and unrealized capital gains and losses of a Fund shall
               be allocated to each class of that Fund on the basis of the
               aggregate net asset value of all outstanding shares ("Record
               Shares") of the Class in relation to the aggregate net asset
               value of Record Shares of the Fund.

                                      -2-
<PAGE>
 
          ii.  Income and expenses of a Fund not charged directly to a
               particular Class shall be allocated to each Class of that Fund on
               the following basis:

               a.   For periodic dividend funds, on the basis of the aggregate
                    net asset value of Record Shares of each Class in relation
                    to the aggregate net asset value of Record Shares of the
                    Fund.

               b.   For daily dividend funds, on the basis of the aggregate net
                    asset value of Settled Shares of each Class in relation to
                    the aggregate net asset value of Settled Shares of the Fund.
                    "Settled Shares" means Record Shares minus the number of
                    shares of that Class or Fund that have been issued but for
                    which payment has not cleared and plus the number of shares
                    of that Class or Fund which have been redeemed but for which
                    payment has not yet been issued.

     D.   On an ongoing basis, the Directors, pursuant to their fiduciary
          responsibilities under the Act and otherwise, will monitor each Fund
          for the existence of any material conflicts among the interests of its
          several Classes.  The Directors, including a majority of the
          Disinterested Directors, shall take such action as is reasonably
          necessary to eliminate any such conflicts that may develop.  The
          Manager and Seligman Financial Services, Inc. (the "Distributor") will
          be responsible for reporting any potential or existing conflicts to
          the Directors.  If a conflict arises, the Manager and the Distributor
          will be responsible at their own expense for remedying such conflict
          by appropriate steps up to and including separating the classes in
          conflict by establishing a new registered management company to
          operate one of the classes.

     E.   The plan of each Fund adopted pursuant to Rule 12b-1 under the Act
          (the "Rule 12b-1 Plan") provides that the Directors will receive
          quarterly and annual statements complying with paragraph (b)(3)(ii) of
          Rule 12b-1, as it may be amended from time to time.  To the extent
          that the Rule 12b-1 Plan in respect of a specific Class is a
          reimbursement plan, then only distribution expenditures properly
          attributable to the sale of shares of that Class will be used in the
          statements to support the Rule 12b-1 fee charged to shareholders of
          such Class.  In such cases expenditures not related to the sale of a
          specific Class will not be presented to the Directors to support Rule
          12b-1 fees charged to shareholders of such Class.  The statements,
          including the allocations upon which they are based, will be subject
          to the review of the Disinterested Directors.

     F.   Dividends paid by a Fund with respect to each Class, to the extent any
          dividends are paid, will be calculated in the same manner, at the same
          time and on the same day and will be in the same amount, except that
          fee payments made under the Rule 12b-1 Plan relating to the Classes
          will be borne exclusively by each Class and except that any Class
          Level Expenses shall be borne by the applicable Class.

     G.   The Directors of each Fund hereby instruct such Fund's independent
          auditors to review expense allocations each year as part of their
          regular audit process, to inform the Directors and the Manager of any
          irregularities detected and, if specifically requested by the
          Directors, to prepare a written report thereon.  In addition, if any
          Special Expense is incurred by a Fund and is classified as a Class
          Level Expense in the manner contemplated by paragraph B. above, the
          independent auditors for such Fund, in addition to reviewing such
          allocation, are hereby instructed to report thereon to the Audit
          Committee of the relevant Fund and to the Manager.  The Manager will
          be responsible for taking such steps as are necessary to remedy any
          irregularities so detected, and will do so at its own expense to the
          extent such irregularities should reasonably have been detected and
          prevented by the Manager in the performance of its services to the
          Fund.
