  The purpose of this table is to assist investors in understanding the vari-
ous costs and expenses which shareholders of the Fund bear directly or indi-
rectly. The sales load on Class A shares is a one-time charge paid at the time
of purchase of shares. Reductions in sales loads are available in certain cir-
cumstances. The contingent deferred sales load on Class D shares is a one-time
charge paid only if shares are redeemed within one year of purchase. For more
information concerning reduction in sales loads and for a more complete de-
scription of the various costs and expenses, see "Purchase Of Shares," "Re-
demption Of Shares" and "Management Services" herein. The Fund's Administra-
tion, Shareholder Services and Distribution Plan to which the caption "12b-1
Fees" relates, is discussed under "Administration, Shareholder Services and
Distribution Plan" herein.
   
  The table reflects actual 1994 expenses, except for the 12b-1 fee for Class
A shares which has been restated to reflect the estimated effect of payment
which may be made to Seligman Services, Inc. ("SSI"), an affiliate of the Man-
ager, which has been established as a limited purpose broker/dealer. SSI shall
act as broker/dealer of record for most shareholder accounts that do not have
a designated broker/dealer of record including all such shareholder accounts
established after April 1, 1995 and will receive compensation for providing
personal service and account maintenance to its accounts of record.

You would pay the following expenses on a
 $1,000 investment, assuming (1) 5% annual
 return and (2) redemption at the end of each
 time period:
Class A.......................................  $57     $76    $ 98     $159
Class D.......................................  $30+    $62    $106     $229
</TABLE>    
 
THE EXAMPLE SHOULD NOT BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE EX-
PENSES. ACTUAL EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN AND THE 5% AN-
NUAL RETURN USED IN THIS EXAMPLE IS A HYPOTHETICAL RATE.
          
* Includes an annual distribution fee of .75 of 1% and an annual service fee
  of .25 of 1%. Pursuant to the Rules of the National Association of Securities
  Dealers, Inc., the aggregate deferred sales loads and annual distribution
  fees on Class D shares of the Fund may not exceed 6.25% of total gross sales,
  subject to certain exclusions. The 6.25% limitation is imposed on the Fund
  rather than on a per shareholder basis. Therefore, a long-term Class D share-
  holder 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 the shares.     
   
+ Assuming (1) 5% annual return and (2) no redemption at the end of one year,
  the expenses on a $1,000 investment would be $20.

                              FINANCIAL HIGHLIGHTS
   
  The Fund's financial highlights for the periods presented below have been au-
dited by Deloitte & Touche LLP, independent auditors. This information, which
is derived from the financial and accounting records of the Fund, should be
read in conjunction with the 1994 financial statements and notes contained in
the 1994 Annual Report, which may be obtained by calling or writing the Fund at
the telephone numbers or address provided on the cover page of this Prospectus.
    
  The per share operating performance data is designed to allow investors to
trace the operating performance, on a per share basis, from the Fund's begin-
ning net asset value to its ending net asset value so that investors may under-
stand what effect the individual items have on their investment, assuming it
was held throughout the period. Generally, the per share amounts are derived by
converting the actual dollar amounts incurred for each item, as disclosed in
the financial statements, to their equivalent per share amount.
 
  The total return based on net asset value measures the Fund's performance 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 in-
vestors may incur in purchasing or selling shares of the Fund. The total re-
turns for periods of less than one year are not annualized.

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

set forth below. Each class has advantages and disadvantages for different in-
vestors, and investors should choose the class that best suits their circum-
stances and their objectives.

INVESTMENT OBJECTIVES, 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 1930.
 
  The Fund strives to produce favorable, but not the highest, current income
and long-term growth of both income and capital value, without exposing capital
to undue risk. Income is thought of in terms of both the dollar amount of divi-
dends paid and the purchasing power of the income they provide.
   
  The Fund emphasizes careful selection of individual securities suited to its
investment objectives, broad diversification of investment risk and continuing
supervision of securities owned. Assets may be held in cash or invested in all
forms of securities. For many years, common stocks have made up the bulk of se-
curities owned. However, substantial proportions of assets have been held, and
may be held, in cash and fixed income securities. Investments may be changed
whenever considered advisable and portfolio turnover may vary with such
changes. There can be no assurance that the Fund will attain its investment ob-
jectives.     
 
  LENDING OF PORTFOLIO SECURITIES. The Fund may lend portfolio securities to
brokers or dealers in corporate or government securities, or banks or other in-
stitutional 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 portfolio securities are on loan, the bor-
rower 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 borrow-
er.
   
  RESTRICTED SECURITIES. The Fund may invest up to 15% of its net assets in il-
liquid securities, including restricted securities (i.e., securities not read-
ily marketable without registration under the Securities Act of 1933 (the "1933
Act")) and other securities that are not readily marketable. The Fund may pur-
chase restricted securities that can be offered and sold to "qualified institu-
tional buyers" under Rule 144A of the 1993 Act, and the Fund's Board of Direc-
tors may determine, when appropriate, that specific Rule 144A securities are
liquid and not subject to the 15% limitation on illiquid securities. Should the
Board of Directors make this determination, it will carefully monitor the secu-
rity (focusing on such factors, among others, as trading activity and avail-
ability of information) to determine that the Rule 144A security continues to
be liquid. It is not possible to predict with assurance exactly how the market
for restricted securities offered and sold under Rule 144A will develop. This
investment practice could have the effect of increasing the level of illiquid-
ity in the Fund to the extent that qualified institutional buyers become for a
time uninterested in purchasing Rule 144A securities.     
   
  FOREIGN SECURITIES. The Fund may invest in commercial paper and certificates
of deposit issued by foreign banks and may invest in other securities of for-
eign issuers directly or through American Depository Receipts ("ADRs"), Euro-
pean Depository Receipts ("EDRs") or Global Depository Receipts ("GDRs") (col-
lectively, "Depository Receipts"). Foreign investments may be affected favor-
ably or unfa     
 
                                       5

vorably by changes in currency rates and exchange control regulations. There
may be less information available about a foreign company than about a U.S.
company and foreign companies may not be subject to reporting standards and re-
quirements 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 bro-
kerage commissions and custody fees are generally higher than those in the
United States. Investments in foreign securities may also be subject to local
economic or political risks, political instability and possible nationalization
of issuers. Depository Receipts are instruments generally issued by domestic
banks or trust companies that represent the deposits of a security of a foreign
issuer. ADRs may be publicly traded on exchanges or over-the-counter in the
United States and are quoted and settled in dollars at a price that generally
reflects the dollar equivalent of the home country share price. EDRs and GDRs
are typically traded in Europe and in both Europe and the United States, re-
spectively. Depository Receipts may be issued under sponsored or unsponsored
programs. In sponsored programs, the issuer has made arrangements to have its
securities traded in the form of a Depository Receipt. In unsponsored programs,
the issuers may not be directly involved in the creation of the program. Al-
though regulatory requirements with respect to sponsored and unsponsored Depos-
itory Receipt programs are generally similar, the issuers of securities repre-
sented by unsponsored Depository Receipts are not obligated to disclose mate-
rial information in the United States, and therefore, the import of such infor-
mation may not be reflected in the market value of such receipts. The Fund may
invest up to 10% of its total assets in foreign securities that it holds di-
rectly, but this 10% limit does not apply to foreign securities held through
Depository Receipts which are traded in the United States or to commercial pa-
per and certificates of deposit issued by foreign banks.     
   
  Except as noted above, the foregoing investment policies are not fundamental
and the Board of Directors of the Fund may change such policies without the
vote of a majority of its outstanding voting securities. As a matter of policy,
the Board would not change the Fund's investment objective of seeking to pro-
duce favorable, but not the highest, current income and long-term growth of
both income and capital value 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,
appears 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
Communications and Information Fund, Inc., Seligman Frontier Fund, Inc., Selig-
man 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 Port-
folios, Inc., Seligman Quality Municipal Fund, Inc., Seligman Select Municipal
Fund, Inc., Seligman Tax-Exempt Fund Series, Inc., Seligman Tax-Exempt Series
Trust and Tri-Continental Corporation. The aggregate     
 
                                       6
<PAGE>
 
   
assets of the Seligman Group are approximately $7.3 billion. The Manager also
provides investment management or advice to institutional accounts having an
aggregate value of approximately $3.3 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 major-
ity of the outstanding voting securities of the Manager.
   
  The Manager provides senior management for Seligman Data Corp., a wholly-
owned subsidiary of the Fund and certain other investment companies in the Se-
ligman Group, which performs, at cost, certain recordkeeping functions for the
Fund, maintains the records of shareholder accounts and furnishes dividend pay-
ing, redemption and related services.     
          
  The Manager is entitled to receive a management fee, calculated daily and
payable monthly, based on a percentage of the daily net assets of the Fund. In
1994, the management fee paid by the Fund was equal to an annual rate of .49%
of the average daily net assets of the Fund. The method for determining the
management fee is set forth in the Appendix. The Fund pays all of its expenses
other than those assumed by the Manager. Total expenses of the Fund's Class A
and Class D shares, respectively, for the year ended December 31, 1994 amounted
to .85% and 1.96%, respectively, of the average daily net assets of each class.
       
   THE SUBADVISER. On May 19, 1994, shareholders of the Fund approved a
Subadvisory Agreement between the Manager and Seligman Henderson Co. (the
"Subadviser") that provides that the Subadviser shall act as Subadviser to the
Fund with respect to a portion of the Fund's assets as designated by the Manag-
er, which shall include all or a portion of the Fund's foreign investments
("Qualifying Assets"). The Fund has a non-fundamental policy under which it may
invest up to 10% of its total assets in foreign securities that are held di-
rectly. The 10% limit does not apply to foreign securities held through Deposi-
tory Receipts which are traded in the United States or to commercial paper and
certificates of deposit issued by foreign banks. The Subadviser serves the Fund
pursuant to a Subadvisory Agreement with the Manager (the "Subadvisory Agree-
ment"), dated June 1, 1994. The Subadvisory Agreement provides that the
Subadviser provides investment management services with respect to the Qualify-
ing Assets, including investment research, advice and supervision, determines
which securities will be purchased or sold, makes purchases and sales on behalf
of the Fund and determines how voting and other rights with respect to securi-
ties held by the Fund shall be exercised, subject in each case to the control
of the Board of Directors and in accordance with the Fund's investment objec-
tives, policies and principles. For this service, the Subadviser receives a fee
from the Manager, calculated pursuant to the method set forth in the Appendix.
For the period June 1, 1994 through December 31, 1994, the Subadviser received
a fee of $146,005.     
   
  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 Communica-
tions and Information Funds, Inc., Seligman Frontier Fund, Inc., Seligman
Growth Fund, Inc., Seligman Henderson Global Fund Series, Inc., Seligman Income
Fund, Inc., the Global Portfolio and Global Smaller Companies Portfolio of Se-
ligman Portfolios, Inc., Tri-Continental Corporation, the International Equity
Fund of The Compass Capital Group, and the Seligman Henderson International
Small Capital Portfolio and Seligman Henderson International Equity Portfolio
of the American Skandia Trust. The address of the Subadviser is 100 Park Ave-
nue, New York, NY 10017.

  PORTFOLIO TRANSACTIONS. The Management Agreement and Subadvisory Agreement
recognize that in the purchase and sale of portfolio securities, the Manager
and Subadviser will seek the most favorable price and execution and, consistent
with that policy, may give consideration to the research, statistical and other
services furnished by brokers or dealers to the Manager and Subadviser. The use
of brokers who provide investment and market research and securities and eco-
nomic analysis may result in higher brokerage charges than the use of brokers
selected on the basis of the most favorable brokerage commission rates, and re-
search and analysis received may be useful to the Manager and Subadviser in
connection with its services to other clients as well as to the Fund. In over-
the-counter markets, orders are placed with responsible primary market makers
unless a more favorable execution or price is believed to be obtainable.     
   
  Consistent with the rules of the National Association of Securities Dealers,
Inc., and subject to seeking the most favorable price and execution available
and such other policies as the Directors may determine, the Manager and
Subadviser may consider sales of shares of the Fund and, if permitted by appli-
cable laws, may consider sales of shares of the other funds in the Seligman
Group as a factor in the selection of brokers or dealers to execute portfolio
transactions for the Fund.     
          
  PORTFOLIO TURNOVER. A change in securities held by the Fund is known as
"portfolio turnover" which may result in the payment by the Fund of dealer
spreads or underwriting commissions and other transaction costs on the sale of
securities as well as on the reinvestment of the proceeds in other securities.
Although it is the policy of the Fund to hold securities for investment,
changes in securities held by the Fund will be made from time to time when the
Manager and Subadviser believe such changes will strengthen the Fund's
portfolio. The portfolio turnover of the Fund is not expected to exceed 100%.

PURCHASE OF SHARES
 
  Seligman Financial Services, Inc. ("SFSI"), an affiliate of the Manager, acts
as general distributor of the Fund's shares. Its address is 100 Park Avenue,
New York, New York 10017.
 
  The Fund issues two classes of shares: Class A shares are sold to investors
choosing the initial sales load alternative; and Class D shares are sold to in-
vestors choosing no initial sales load, a higher distribution fee and a CDSL on
redemptions within one year of purchase. See "Alternative Distribution System"
above.
 
  Shares of the Fund may be purchased through any authorized investment dealer.
All orders will be executed at the net asset value per share next computed af-
ter receipt of the purchase order plus, in the case of Class A shares, a sales
load which, except for shares purchased under one of the reduced sales load
plans, will vary with the size of the purchase as shown in the schedule under
"Class A Shares--Initial Sales Load" below.
   
  THE MINIMUM AMOUNT FOR INITIAL INVESTMENT IN THE FUND IS $1,000 (EXCEPT FOR
AN ACCOUNT BEING ESTABLISHED PURSUANT TO THE INVEST-A-CHECK (R) SERVICE) SUBSE-
QUENT INVESTMENTS MUST BE IN THE MINIMUM AMOUNT OF $100 (EXCEPT FOR INVESTMENT
OF DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS). THE FUND RESERVES THE RIGHT TO
RETURN INVESTMENTS THAT DO NOT MEET THESE MINIMUMS.     
   
  Orders received by an authorized dealer before the close of the New York
Stock Exchange ("NYSE") (4:00 p.m. Eastern time) and accepted by SFSI before
the close of business (5:00 p.m. Eastern time) on the same day will be executed
at the Fund's net asset value determined as of the close of the NYSE on that
day plus, in the case of Class A shares, the applicable sales load. Orders ac-
cepted by dealers after the close of the NYSE, or received by SFSI after the
close of business, will be executed at the Fund's net asset value as next de-
termined plus, in the case of Class A shares, the applicable sales load. The
authorized dealer through which a shareholder purchases shares is responsible
for forwarding the order to SFSI promptly.     
   
  Payment for dealer purchases may be made by check or by wire. To wire pay-
ments, dealer orders must first be placed through SFSI's order desk and as-
signed a purchase confirmation number. Funds in payment of the purchase may
then be wired to Mellon Bank, N.A., ABA #043000261, A/C Seligman Common Stock
Fund, Inc. (A 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 Seligman Data Corp.
for specific wire instructions. Although the Fund makes no charge for this
service, the transmitting bank may impose a wire service fee.     
   
  Existing shareholders may purchase additional shares at any time through any
authorized dealer or by sending a check payable to the "Seligman Group of Mu-
tual Funds" directly to P.O. BOX 3936, NEW YORK, NY 10008-3936. Checks for in-
vestment must be in U.S. dollars drawn on a domestic bank. The check should in-
clude the shareholder's name, address, account number, name of Fund and class
of shares. If a shareholder does not indicate the required information, Selig-
man Data Corp. will seek further clarification and may be forced to return the
check to the shareholder. If only the class designation is missing, the invest-
ment will automatically be made in Class A shares. Orders sent directly to Se-
ligman Data Corp. will be executed at the Fund's net asset value next deter-
mined after the order is accepted plus, in the case of Class A shares, the ap-
plicable sales load.     
   
  Seligman Data Corp. will charge a $10.00 service fee for checks returned to
it marked "unpaid." This charge may be deducted from the account that requested
the purchase. For the protection of the Fund and its shareholders, no redemp-
tion proceeds will be remitted to a shareholder with respect to shares pur-
chased by check (unless certified) until Seligman Data Corp. receives notice
that the check has cleared,     
 
                                       9

which may be up to 15 days from the credit of the shares to the shareholder's
account.     
   
  VALUATION. The net asset value of the Fund's shares is determined each day,
Monday through Friday, as of the close of trading on the NYSE (usually 4:00
p.m. Eastern time) on each day that the NYSE is open for business. Net asset
value is calculated separately for each class. Securities traded on a U.S. or
foreign exchange or over-the-counter market are valued at the last sales price
on the primary exchange or market on which they are traded. United Kingdom se-
curities and securities for which there are no recent sales transactions are
valued based on quotations provided by primary market makers in such securi-
ties. Any securities for which recent market quotations are not readily avail-
able are valued at fair value determined in accordance with procedures approved
by the Board of Directors. Short-term holdings maturing in 60 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 and Class D shares are substantially
identical, the different expenses borne by each class will result in different
net asset values and dividends. The net asset value of Class D shares will gen-
erally be lower than the net asset value of Class A shares as a result of the
larger distribution fee charged to Class D shares. In addition, net asset value
per share of the two classes will be affected to the extent any other class ex-
pense differs among classes.     
 
  CLASS A SHARES--INITIAL SALES LOAD. Class A shares are subject to an initial
sales load which varies with the size of the purchase as shown in the following
schedule, and an annual service fee of up to .25% of the average daily net as-
set value of Class A shares. See "Administration, Shareholder Services and Dis-
tribution Plan" below.

  REDUCED SALES LOADS. Reductions in sales loads apply to purchases of Class A
shares by a "single person," including an individual, members of a family unit
comprising husband, wife and minor children purchasing securities for their own
account, or a trustee or other fiduciary purchasing for a single fiduciary ac-
count or single trust. Purchases made by a trustee or other fiduciary for a fi-
duciary account may not be aggregated with purchases made on behalf of any
other fiduciary or individual account.
       
. VOLUME DISCOUNTS are provided if the total amount being invested in Class A
shares of the Fund alone, or in any combination of shares of the other funds in
the Seligman Group that are sold with a sales load, reaches levels indicated in
the above sales load schedule.
   
. THE RIGHT OF ACCUMULATION allows an investor to combine the amount being in-
vested in Class A shares of the other mutual funds in the Seligman Group sold
with a sales load with the total net asset value of shares of those funds al-
ready owned that were sold with a sales load and the total net asset value of
shares of Seligman Cash Management Fund that were     
 
                                       10
<PAGE>
 
   
acquired by the investor through an exchange of shares of another mutual fund
in the Seligman Group on which there was a sales load to determine reduced
sales loads in accordance with the sales load schedule. An investor or a dealer
purchasing shares on 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 mu-
tual funds in the Seligman Group already owned that were sold with a sales load
and the total net asset value of shares of Seligman Cash Management Fund that
were acquired through an exchange of shares of another mutual fund in the Se-
ligman Group on which there was a sales load. An investor or a dealer purchas-
ing shares on behalf of an investor must indicate that the investor has exist-
ing accounts when making investments or opening new accounts. For more informa-
tion concerning terms of Letters of Intent, see "Terms and Conditions" on
page 25.     
 
  SPECIAL PROGRAMS. The Fund may sell Class A shares at net asset value to
present and retired directors, trustees, officers, employees (and their spouses
and minor children) of the Fund, the other investment companies in the Seligman
Group, the Manager and other companies affiliated with the Manager. Such sales
also may be made to employee benefit and thrift plans for such 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 per-
sonal holding companies; to any registered unit investment trust which is the
issuer of periodic payment plan certificates, the net proceeds of which are in-
vested 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 similar to the Fund
who purchase shares with redemption proceeds of such funds; to financial insti-
tution trust departments; to registered investment advisers exercising discre-
tionary investment authority with respect to the purchase of Fund shares; to
accounts of financial institutions or broker/dealers that charge account man-
agement fees, provided the Manager or one of its affiliates has entered into an
agreement with respect to such accounts; pursuant to sponsored arrangements
with organizations which make recommendations to or permit group solicitations
of, its employees, members or participants in connection with the purchase of
shares of the Fund; and to "eligible employee benefit plans" of employers who
have at least 2,000 U.S. employees to whom such plan is made available and, re-
gardless of the number of employees, if such plan is established and maintained
by any dealer that has a sales agreement with SFSI. "Eligible employee benefit
plans" means any plan or arrangement, whether or not tax qualified, which pro-
vides for the purchase of Fund shares. Sales of shares to such plans must be
made in connection with a payroll deduction system of plan funding or other
system acceptable to Seligman Data Corp.     
   
  For the period February 22, 1995 and continuing until June 30, 1995,
broker/dealers will receive the full sales load in accordance with the above
sales load schedule (up to 4.75%) on sales of Class A shares. After June 30,
1995, regular broker/dealer concessions (up to 4.25%) will be paid on Class A
shares of the Fund.     
 
  CLASS D SHARES. Class D shares are sold without an initial sales load but are
subject to a CDSL if the shares are redeemed within one year, an annual dis-
tribution fee of up to .75 of 1% and an annual service fee of up to .25 of 1%,
of the average daily net asset value of the Class D shares. SFSI will make a 1%
payment to dealers in respect of purchases of Class D shares.
 
                                       11
<PAGE>
 
  A CDSL will be imposed on any redemption of Class D shares which were pur-
chased during the preceding twelve months; however, no such charge will be im-
posed on shares acquired through the investment of dividends or distributions
from any Class D shares within the Seligman Group. The amount of any CDSL will
be paid to and retained by SFSI.
 
  To minimize the application of CDSL to a redemption, shares acquired pursuant
to the investment of dividends and distributions will be redeemed first; fol-
lowed by shares purchased at least one year prior to the redemption. Shares
held for the longest period of time within the applicable one year period will
then be redeemed. Additionally, for those shares determined to be subject to
the CDSL, the application of the 1% CDSL will be made to the current net asset
value or original purchase price, whichever is less.
 
  For example, assume an investor purchased 100 shares in January at a price of
$10.00 per share. During the first year, 5 additional shares were acquired
through investment of dividends and distributions. In January of the following
year, an additional 50 shares are purchased at a price of $12.00 per share. In
March of that year, the investor chooses to redeem $1,500.00 from the account
which now holds 155 shares with a total value of $1,898.75 ($12.25 per 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 Code section 403(b)(7) or an individ-
ual retirement account ("IRA") due to death, disability, or attainment of age
59 1/2, and (iii) a tax-free return of an excess contribution to an IRA; (c) in
whole or in part, in connection with shares sold to current and retired Direc-
tors of the Fund; (d) in whole or in part, in connection with shares sold to
any state, county, or city or any instrumentality, department, authority, or
agency thereof, which is prohibited by applicable investment laws from paying a
sales load or commission in connection with the purchase of shares of any reg-
istered investment management company; (e) pursuant to an automatic cash with-
drawal service; (f) in connection with the redemption of Class D shares of the
Fund if it is combined with another mutual fund in the Seligman Group, or an-
other similar reorganization transaction; and (g) in connection with the Fund's
right to redeem or liquidate an account that holds below a certain minimum num-
ber or dollar amount of shares (currently $500).
 
  If, with respect to a redemption of any Class D shares sold by a dealer, the
CDSL is waived because the redemption qualifies for a waiver as set forth
above, the dealer shall remit to SFSI promptly upon notice an amount equal to
the 1% payment or a portion of the 1% payment paid on such shares.

  SFSI may from time to time assist dealers by, among other things, providing
sales literature to, and holding informational programs for the benefit of,
dealers' registered representatives. Dealers may limit the participation of
registered representatives in such informational programs by means of sales in-
centive programs which may require the sale of minimum dollar amounts of shares
of the Seligman Mutual Funds. SFSI may from time to time pay a bonus or other
incentive to dealers that sell shares of the mutual funds in the Seligman
Group. In some instances, these bonuses or incentives may be offered only to
certain dealers which employ registered representatives who have sold or may
sell a significant amount of shares of the Fund and/or certain other funds man-
aged by the Manager during a specified period of time. Such bonus or other in-
centive may take the form of payment for travel expenses, including lodging,
incurred in connection with trips taken by qualifying registered representa-
tives and members of their families to places within or outside the United
States. The cost to SFSI of such promotional activities and payments shall be
consistent with the rules of the National Association of Securities Dealers,
Inc., as then in effect.     
   
TELEPHONE TRANSACTIONS     
   
  A shareholder whose account has either an individual or joint tenancy regis-
tration may elect to effect the following transactions via telephone by com-
pleting the Telephone Service Election portion of the Account Application or a
separate Telephone Service Election Form: (i) redemption of Fund shares, (ii)
exchange of Fund shares for shares of another Seligman Mutual Fund, (iii)
change of a dividend and/or capital gain distribution option, and (iv) change
of address. IRA accounts may only elect to effect exchanges or address changes.
By completing the appropriate section of the Account Application or separate
Election Form, all Seligman Mutual Funds with the same account number (i.e.,
registered in exactly the same names), including any new fund in which the
shareholder invests in the future, will automatically have telephone services.
All telephone transactions are effected through Seligman Data Corp. at (800)
221-2450.     
   
  For accounts registered as joint tenancies, each joint tenant, by electing
telephone transaction services, authorizes each of the other tenants to effect
telephone transactions on his or her behalf.     
   
  During times of drastic economic or market changes, a shareholder may experi-
ence difficulty in contacting Seligman Data Corp. to request a redemption or
exchange of Fund shares. In these circumstances, the shareholder should con-
sider using other redemption or exchange procedures. (See "Redemption Of
Shares" below.) Use of these other redemption or exchange procedures will re-
sult in the redemption request being processed at a later time than if tele-
phone transactions had been used, and the Fund's net asset value may fluctuate
during such periods.     
   
  The Fund and Seligman Data Corp. will employ reasonable procedures to confirm
that instructions communicated by telephone are genuine. These will include:
recording all telephone calls requesting account activity, requiring that the
caller provide certain requested personal and/or account information at the
time of the call for the purpose of establishing the caller's identity, and
sending a written confirmation of redemptions, exchanges or address changes to
the address of record each time activity is initiated by telephone. As long as
the Fund and Seligman Data Corp. follow instructions communicated by telephone
that were reasonably believed to be genuine at the time of their receipt, nei-
ther they nor any of their affiliates will be liable for any loss to the share-
holder caused by an unauthorized transaction. Shareholders are, of course, un-
der no obligation to apply for telephone transaction services. In any instance
where the Fund or Seligman Data Corp. is not reasonably satisfied that instruc-
tions received by telephone are genuine, the requested transaction will not be
executed, and neither they nor any of their affiliates will be liable for any
losses which may occur due to a delay in implementing the transac     
 
                                       13
<PAGE>
 
   
tion. If the Fund or Seligman Data Corp. does not follow the procedures de-
scribed above, the Fund or Seligman Data Corp. may be liable for any losses due
to unauthorized or fraudulent instructions. Telephone services must be effected
through a representative of Seligman Data Corp., i.e., requests may not be com-
municated via Seligman Data Corp.'s automated telephone answering system. Tele-
phone transaction services may be terminated by a shareholder at any time by
sending a written request to Seligman Data Corp. Written acknowledgment of ter-
mination of telephone transaction services will be sent to the shareholder.
    
REDEMPTION OF SHARES
   
  A shareholder may redeem shares held in book credit form without charge (ex-
cept a CDSL, if applicable) at any time by SENDING A WRITTEN REQUEST to Selig-
man Data Corp., 100 Park Avenue, New York, New York, 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 account number, class of
shares (A or D) and the number of shares or dollar amount to be redeemed. The
Fund cannot accept conditional redemption requests. If the redemption proceeds
are (i) $50,000 or more, (ii) to be paid to someone other than the shareholder
of record (regardless of the amount) or (iii) to be mailed to other than the
address of record (regardless of the amount), the signature(s) of the share-
holder(s) must be guaranteed by an eligible financial institution including,
but not limited to, the following: banks, trust companies, credit unions, secu-
rities brokers and dealers, savings and loan associations and participants in
the Securities Transfer Association Medallion Program (STAMP), the Stock Ex-
changes Medallion Program (SEMP) or the New York Stock Exchange Medallion Sig-
nature Program (MSP). The Fund reserves the right to reject a signature guaran-
tee where it is believed that the Fund will be placed at risk by accepting such
guarantee. A signature guarantee is also necessary in order to change the ac-
count registration. Notarization by a notary public is not an acceptable signa-
ture 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 INFORMATION WITH RESPECT
TO NECESSARY REDEMPTION REQUIREMENTS, PLEASE CONTACT THE SHAREHOLDER SERVICES
DEPARTMENT OF SELIGMAN DATA CORP. FOR ASSISTANCE. In the case of Class A
shares, and in the case of Class D shares redeemed after one year, a share-
holder will receive the net asset value per share next determined after receipt
of a request in good order. If Class D shares are redeemed within one year of
purchase, a shareholder will receive the net asset value per share next deter-
mined after receipt of a request in good order, less a CDSL of 1% as described
under "Purchase Of Shares--Class D Shares" above.     
   
  A shareholder also may "sell" shares to the Fund through an investment dealer
and, in that way, be certain, providing the order is timely, of receiving the
net asset value established at the end of the day on which the dealer is given
the repurchase order. The Fund makes no charge for this transaction, but the
dealer may charge you a service fee. "Sell" or repurchase orders received from
an authorized dealer before the close of the NYSE and received by SFSI, the re-
purchase agent, before the close of business on the same day will be executed
at the net asset value per share determined as of the close of the NYSE on that
day. Repurchase orders received from authorized dealers after the close of the
NYSE or not received by SFSI prior to the close of business will be executed at
the net asset value determined as of the close of the NYSE on the next trading
day. Shares held in a "street name" account with a broker/dealer may be sold to
the Fund only through a broker/dealer.

  TELEPHONE REDEMPTIONS. Telephone redemptions of uncertificated shares may be
made in an amount of up to $50,000 per day, per account. One telephone redemp-
tion request per day is permitted. Telephone redemption requests must be re-
ceived by Seligman Data Corp. at (800) 221-2450 between 8:30 a.m. and 4:00 p.m.
Eastern time, on any business day and will be processed as of the close of
business on that day. Redemption requests by telephone will not be accepted
within 30 days following an address change. Keogh Plans, IRAs or other retire-
ment plans are not eligible for telephone redemptions. The Fund reserves the
right to suspend or terminate its telephone redemption service at any time
without notice.     
   
  GENERAL. Whether shares are redeemed or repurchased, a check for the proceeds
will be sent to the address of record within seven calendar days after accept-
ance of the redemption or repurchase order and will be made payable to all of
the registered owners on the account. The Fund will not permit redemptions of
shares purchased by check (unless certified) until Seligman Data Corp. receives
notice that the check has cleared, which may be up to 15 days from the credit
of such shares to the shareholder's account. The proceeds of a redemption or
repurchase may be more or less than the shareholder's cost.     
   
  The Fund reserves the right to redeem shares owned by a shareholder whose in-
vestment in the Fund has a value of less than a minimum amount specified by the
Fund's Board of Directors, which is presently $500. Shareholders are sent a no-
tice before the redemption is processed stating that the value of the invest-
ment 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 de-
cides not to redeem them, or to shift the investment to one of the other mutual
funds in the Seligman Group, the shareholder may, within 120 calendar days of
the date of the redemption, use all or any part of the proceeds of the redemp-
tion to reinstate, free of sales load, all or any part of the investment in
shares of the Fund or in shares of any of the other mutual funds in the Selig-
man Group. If a shareholder redeems Class D shares and the redemption was sub-
ject to a CDSL the shareholder may reinstate the investment in shares of the
same class of the Fund or of any of the other mutual funds in the Seligman
Group within 120 calendar days of the date of redemption and receive a credit
for the CDSL paid. Such investment will be reinstated at the net asset value
per share established as of the close of the NYSE on the day the request is re-
ceived. Seligman Data Corp. must be informed that the purchase represents a re-
instated investment. REINSTATED SHARES MUST BE REGISTERED EXACTLY AND BE OF THE
SAME CLASS AS THE SHARES PREVIOUSLY REDEEMED.     
 
  Generally, exercise of the Reinstatement Privilege does not alter the Federal
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 reinvested
in shares of the same Fund, some or all of the loss will not be allowed as a
deduction, depending upon the percentage of the proceeds reinvested.
 
ADMINISTRATION, SHAREHOLDER SERVICES AND DISTRIBUTION PLAN
 
  Under the Fund's Administration, Shareholder Services and Distribution Plan
(the "Plan"), the Fund may pay to SFSI an administration, shareholder services
and distribution fee in respect of the Fund's Class A and Class D shares. Pay-
ments under the Plan may include, but are not limited to: (i) compensation to
securities dealers and other organizations ("Service Organizations") for pro-
viding distribution assistance with respect to assets invested in the Fund,
(ii) compensation to Service Organizations for providing administration, ac-
counting and other shareholder services with respect to Fund shareholders, and
(iii) otherwise promoting the sale of shares of the Fund, including paying
 
                                       15
<PAGE>
 
for the preparation of advertising and sales literature and the printing and
distribution of such promotional materials and prospectuses to prospective in-
vestors and defraying SFSI's costs incurred in connection with its marketing
efforts with respect to shares of the Fund. The Manager, in its sole discre-
tion, may also make similar payments 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 Organizations 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, 1994 in respect of the Fund's Class A shares pursuant to the Plan was equal
to .14% of the Class A shares' average daily net assets.     
   
  Under the Plan, the Fund reimburses SFSI for its expenses with respect to
Class D shares at an annual rate of up to 1% of the average daily net asset
value of the Class D shares. Proceeds from the Class D distribution fee are
used primarily to compensate Service Organizations for administration, share-
holder services and distribution assistance (including a continuing fee of up
to .25% on an annual basis of the average daily net asset value of Class D
shares attributable to particular Service Organizations for providing personal
services and/or the maintenance of shareholder accounts) and will initially be
used by SFSI to defray the expense of the 1% payment made by it to Service Or-
ganizations at the time of the sale of Class D shares. The amounts expended by
SFSI in any one year upon the initial purchase of Class D shares may exceed the
amounts received by it from Plan payments retained. Expenses of administration,
shareholder services and distribution of Class D shares in one fiscal year of
the Fund may be paid from Class D Plan fees received from the Fund in any other
fiscal year.     
   
  The Plan, as it relates to Class D shares, was approved by the Directors on
March 18, 1993 and became effective May 1, 1993. The Plan is reviewed by the
Directors annually. The total amount paid for the year ended December 31, 1994
by the Fund's Class D shares pursuant to the Plan was 1% per annum of the aver-
age daily net assets of Class D shares.     
   
  Seligman Services, Inc. ("SSI"), an affiliate of the Manager, is a limited
purpose broker/dealer. SSI shall act as broker/dealer of record for most share-
holder accounts that do not have a designated broker/dealer of record including
all such shareholder accounts established after April 1, 1995 and will receive
compensation for providing personal service and account maintenance to its ac-
counts of record.     
 
EXCHANGE PRIVILEGE
   
  A shareholder of the Fund may, without charge, exchange at net asset value
any or all of an investment in the Fund for shares of any of the other mutual
funds in the Seligman Group. Exchanges may be made by mail, or by telephone, if
telephone services are elected by the shareholder.     
 
  Class A and Class D shares may be exchanged only for Class A and Class D
shares, respectively, of
 
                                       16

another mutual fund in the Seligman Group on the basis of relative net asset
value.     
 
  If Class D shares that are subject to a CDSL are exchanged for Class D shares
of another fund, for purposes of assessing the CDSL payable upon disposition of
the exchanged Class D shares, the one year holding period shall be reduced by
the holding period of the original Class D shares.

  All permitted exchanges will be based on the then current net asset values of
the respective funds. Telephone requests for exchanges must be 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, and 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 ex-
changed 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 receiv-
ing distributions, unless otherwise indicated, will be carried over to the     
 
                                       17
<PAGE>
 
   
new Fund account. Account services, such as Invest-A-Check (R) Service, Di-
rected 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 ex-
change of all shares held. Shares for which certificates have been issued may
not be exchanged via telephone and may be exchanged only upon receipt of a
written exchange request together with certificates representing shares to be
exchanged in form for transfer.     
   
  Telephone exchanges are only available to shareholders whose accounts are
registered individually, as joint tenancies or IRAs. The Exchange Privilege via
mail is generally applicable to investments in an IRA and other retirement
plans, although some restrictions may apply and may be applicable to other mu-
tual funds in the Seligman Group that may be organized by the Manager in the
future. The terms of the exchange offer described herein may be modified at any
time; 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 con-
tact an authorized investment dealer or Seligman Data Corp. to obtain prospec-
tuses of any of the mutual funds in the Seligman Group.     
   
  A broker/dealer of record will be able to effect exchanges on behalf of a
shareholder only if the broker/dealer has entered into a Telephone Exchange
Agreement with SFSI wherein the broker/dealer must agree to indemnify SFSI and
the mutual funds in the Seligman Group from any loss or liability incurred as a
result of the acceptance of telephone exchange orders.     
   
  Written confirmation of all exchanges will be forwarded to the shareholder to
whom the exchanged shares are registered and a duplicate confirmation will be
sent to the dealer of record listed on the account. SFSI reserves the right to
reject a telephone exchange request. The Fund reserves the right to reject any
telephone requests for transactions with a share value exceeding $250,000. Any
rejected telephone exchange order may be processed by mail. For more informa-
tion about telephone exchanges, including the procedure for electing such serv-
ice and the circumstances under which shareholders may bear the risk of loss
for a fraudulent transaction, see "Telephone Transactions" above.     
 
  Exchanges of shares are sales, and may result in a gain or loss for Federal
income tax purposes.
   
FURTHER INFORMATION ABOUT TRANSACTIONS IN THE FUND     
   
  Because excessive trading (including short-term, "market timing" trading) can
hurt the Fund's performance, the Fund may refuse any exchange (1) from any
shareholder account from which there have been two exchanges in the preceding
three month period, or (2) where the exchanged shares equal in value the lesser
of $1,000,000 or 1% of the Fund's net assets. The Fund may also refuse any ex-
change or purchase order from any shareholder account if the shareholder or the
shareholder's broker/dealer has been advised that previous patterns of pur-
chases and redemptions or exchanges have been considered excessive. Accounts
under common ownership or control, including those with the same taxpayer ID
number and those administered so as to redeem or purchase shares based upon
certain predetermined market indicators, will be considered one account for
this purpose. Additionally, the Fund reserves the right to refuse any order for
the purchase of shares.     
 
DIVIDENDS AND DISTRIBUTIONS
 
  The Fund's net investment income is paid to shareholders in dividends quar-
terly, usually in March, June, September and December. Payments vary in amount
depending on income received from portfolio securities and the costs of opera-
tions. The Fund distributes substantially all of any taxable net long-term
 
                                       18
<PAGE>
 
and short-term gain realized on investments to shareholders at least annually.
Such distributions will generally be taxable to shareholders in the year in
which they are declared by the Fund if paid before February 1 of the following
year.
   
  Shareholders may elect: (1) to receive both dividends and gain distributions
in shares; (2) to receive dividends in cash and gain distributions in shares;
(3) to receive both dividends and gain distributions in cash. In the case of
prototype retirement plans, dividends and gain distributions are reinvested in
additional shares. Unless another election is made, dividends and capital gain
distributions will be credited to the 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 at the net asset
value on the ex-dividend date. Shareholders may elect to change their dividend
and gain distribution options by writing Seligman Data Corp. at the address
listed below. If the shareholder has elected telephone services, changes may
also be telephoned to Seligman Data Corp. between 8:00 a.m. and 5:30 p.m. East-
ern time, by either the shareholder or the broker/dealer of record on the ac-
count. For information about electing telephone services, see "Telephone Trans-
actions." 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, otherwise payment will be made in accordance with the
current option on the shareholder's account.     
   
  The per share dividends from net investment income on Class D shares will be
lower than the per share dividends on Class A shares as a result of the higher
distribution fee applicable with respect to Class D shares. Per share dividends
of the two classes may also differ as a result of differing class expenses.
Distributions of net capital gains, if any, will be paid in the same amount for
Class A and Class D shares. See "Purchase Of Shares--Valuation."     
   
  Shareholders exchanging shares of a mutual fund for shares of another mutual
fund in the Seligman Group will continue to receive dividends and gains as
elected prior to such exchange unless otherwise specified. In the event that a
shareholder redeems all shares in an account between the record date and the
payable date, the value of dividends or gain distributions declared will be
paid in cash regardless of the existing election.     
 
FEDERAL INCOME TAXES
   
  The Fund intends to continue to qualify as a regulated investment company un-
der the Internal Revenue Code of 1986, as amended. For each year so qualified,
the Fund will not be subject to Federal income taxes on its net investment in-
come and capital gains, if any, realized during any taxable year, which it dis-
tributes to its shareholders, provided that at least 90% of its net investment
income and net short-term capital gains are distributed to shareholders each
year.     
 
  Dividends from net investment income and distributions from net short-term
capital gains are taxable as ordinary income to the shareholders, whether re-
ceived in cash or reinvested in additional shares, and, to the extent desig-
nated as derived from the Fund's dividend income that would be eligible for the
dividends received deduction if the Fund were not a regulated investment compa-
ny, they are eligible, subject to certain restrictions, for the 70% dividends
received deduction for corporations.
   
  Distributions of net capital gain, i.e., the excess of net long-term capital
gains over any net short-term losses, are taxable as long-term capital gain,
whether received in cash or invested in additional shares, regardless of how
long shares have been held by the shareholders; such distributions are not eli-
gible for the dividends received deduction allowed to corporate shareholders.
    
  Any gain or loss realized upon a sale or redemption of shares in the Fund by
a shareholder who is not
 
                                       19
<PAGE>
 
   
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 capi-
tal gain distribution has been received are subsequently sold or redeemed and
such shares have been held for six months or less, any loss realized will be
treated as long-term capital loss to the extent that it offsets the long-term
capital gain distribution. In addition, no loss will be allowed on the sale or
other disposition of shares of the Fund if, within a period beginning 30 days
before the date of such sale or disposition and ending 30 days after such date,
the holder acquires (such as through dividend reinvestment) securities that are
substantially identical to the shares of the Fund.     
 
  In determining gain or loss on shares of the Fund that are sold or exchanged
within 90 days after acquisition, a shareholder generally will not be permitted
to include in the tax basis attributable to such shares the sales 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 DISTRIBUTIONS AND OTHER
REPORTABLE PAYMENTS TO THE SHAREHOLDER. THE RATE OF BACKUP WITHHOLDING IS 31%.
SHAREHOLDERS SHOULD BE AWARE THAT, UNDER REGULATIONS PROMULGATED BY THE INTER-
NAL REVENUE SERVICE, THE FUND MAY BE FINED $50 ANNUALLY FOR EACH ACCOUNT FOR
WHICH A CERTIFIED TAXPAYER IDENTIFICATION NUMBER IS NOT PROVIDED. IN THE EVENT
THAT SUCH A FINE IS IMPOSED, THE FUND MAY CHARGE A SERVICE FEE OF UP TO $50
WHICH MAY BE DEBITED FROM THE SHAREHOLDER'S ACCOUNT AND OFFSET AGAINST ANY UN-
DISTRIBUTED DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS. THE FUND ALSO RESERVES
THE RIGHT TO CLOSE ANY ACCOUNT WHICH DOES NOT HAVE A CERTIFIED TAXPAYER IDENTI-
FICATION NUMBER.

  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 checks to be
drawn on a regular checking account at regular monthly intervals in fixed
amounts of $100 or more, or regular quarterly intervals in fixed amounts of
$250 or more, to purchase Class A shares. (See "Terms and Conditions" on page
25.)     
   
. AUTOMATIC DOLLAR-COST-AVERAGING SERVICE permits a shareholder to exchange a
specified amount, at regular monthly intervals in fixed amounts of $100 or
more, or regular quarterly intervals in fixed amounts of $250 or more, from
Class A shares of the Fund into Class A shares of any other Seligman Mutual
Fund(s) registered in the same name. The shareholder's account must have a
value of at least $5,000 at the initiation of the service. Exchanges will be
made at the public offering price.     
 
. DIVIDENDS FROM OTHER INVESTMENTS permits a shareholder to order dividends
payable on shares of other companies to be paid to and invested in additional
shares of the Fund. (Dividend checks must meet or exceed the required minimum
purchase amount and include the shareholder's name, the name of the Fund and
the class of shares in which the investment is to be made and the shareholder's
Fund account number.)
   
. AUTOMATIC CD TRANSFER SERVICE permits a shareholder to instruct a bank to in-

any designated Seligman Mutual Fund. Shareholders who wish to use this service
should contact Seligman Data Corp. or a broker to obtain the necessary documen-

Accordingly, it will not normally be advisable to liquidate a CD before its ma-
turity.     
   
. PAYMENTS AT REGULAR INTERVALS can be made to a shareholder who owns or pur-
chases Class A shares worth $5,000 or more held as book credits under the Auto-
matic Cash Withdrawal Service. 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 25.)     
   
. DIRECTED DIVIDENDS allows a shareholder to pay dividends to another person or
to direct the payment of such dividends to another mutual fund in the Seligman
Group for purchase at net asset value. Dividends on Class A and Class D shares
may only be directed to shares of the same class of another mutual fund in the
Seligman Group.     
 
. OVERNIGHT DELIVERY to service shareholder requests is available for a $15.00
fee which may be deducted from a shareholder's account, if requested.

ADVERTISING THE FUND'S PERFORMANCE
   
  From time to time the Fund advertises its "total return" and "average annual
total return," each of which are calculated separately for Class A and Class D
shares. THESE FIGURES ARE BASED ON HISTORICAL EARNINGS AND ARE NOT INTENDED TO
INDICATE FUTURE PERFORMANCE. The "total return" shows what an investment in
shares of Class A and Class D of the Fund would have earned over a specified
period of time (for example, one, five and ten-year periods or since inception)
assuming the payment of the maximum sales load, if any, when the investment was
made and that all distributions and dividends paid by the Fund were reinvested
on the reinvestment dates during the period. The "average annual total return"
is the annual rate required for the initial payment to grow to the amount which
would be received at the end of the specified period (one, five and ten-year
periods or since inception); i.e., the average annual compound rate of return.
The total return and average annual total return of Class A shares quoted from
time to time through December 31, 1992 have not been adjusted to reflect the
deduction of the administration, shareholder services and distribution fee and
through April 10, 1991 also have not been adjusted to reflect the increase in
the management fee approved by shareholders on April 10, 1991, which fees 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-

ORGANIZATION AND CAPITALIZATION
   
  The Fund is an open-end diversified management investment company incorpo-
rated under the laws of the State of Maryland in 1930. The Fund is authorized
to issue 60 million shares of common stock, each with a par value of $0.50, di-
vided into two classes. Each share of the Fund's Class A and Class D common
stock is equal as to earnings, assets and voting privileges, except that each
class bears its own separate distribution and certain other class expenses and
has exclusive voting rights with respect to any matter to which a separate vote
of any class is required by the 1940 Act or Maryland law. The Fund has received
an order from the Securities and Exchange Commission permitting the issuance
and sale of multiple classes of common stock. In accordance with the Articles
of Incorporation, the Board of Directors may authorize the creation of addi-
tional classes of common stock with such characteristics as are permitted by
the order received from the Securities and Exchange Commission. The 1940 Act
requires that where more than one class exists, each class must be preferred
over all other classes in respect of assets specifically allocated to such
class. Shares have non-cumulative voting rights, do not have preemptive or sub-
scription rights and are transferable.

MANAGEMENT FEE
 
  As compensation for the services performed and the facilities and personnel
provided by the Manager, the Fund pays to the Manager promptly after the end of
each month a fee, calculated on each day during such month, equal to the Appli-
cable Percentage of the daily net assets of the Fund at the close of business
on the previous business day. The term "Applicable Percentage" means the amount
(expressed as a percentage and rounded to the nearest one millionth of one per-
cent) obtained by dividing (i) the Fee Amount by (ii) the Fee Base. The term
"Fee Amount" means the sum on an annual basis of:
 
                    .50 of 1% of the first $4 billion of Fee Base,
 
                    .48 of 1% of the next $2 billion of Fee Base,
 
                    .46 of 1% of the next $2 billion of Fee Base, and
 
                    .44 of 1% of Fee Base in excess of $8 billion.
 
  The term "Fee Base" as of any day means the sum of the net assets at the
close of business on the previous day of each of the investment companies reg-
istered under the 1940 Act for which the Manager or any affiliated company acts
as investment adviser or manager (including the Fund).
   
SUBADVISORY FEE     
   
  As compensation for the services performed and the facilities and personnel
provided by the Subadviser, the Manager pays to the Subadviser each month a
fee, equal to the Applicable Percentage of the average monthly Net Qualifying
Assets of the Fund. For this purpose, the term "Net Qualifying Assets" means
the assets designated by the Manager for which the Subadviser provides invest-
ment management services less any related liabilities as designated by the Man-
ager.     
 
  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.

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

                                            AUTHORIZATION
                     I understand  that the telephone  services are optional and
                     that by signing  below I  authorize  the  Funds,  all other
                     Seligman   Funds   with  the  same   account   number   and
                     registration  which I currently own or in which I invest in
                     the future,  and Seligman Data Corp.  ("SDC"),  to act upon
                     instructions  received  by  telephone  from me or any other
                     person  in  accordance   with  the   provisions   regarding
                     telephone  services as set forth in the current  prospectus
                     of  each  such  Fund,  as  amended  from  time to  time.  I
                     understand that redemptions of uncertificated  shares of up
                     to  $50,000  will be sent  only to my  account  address  of
                     record, and only if such address has not changed within the
                     30 days preceding such request. Any telephone  instructions
                     given in respect of this account and any account into which
                     exchanges  are made are  hereby  ratified  and I agree that
                     neither  the  Fund(s)  nor SDC will be liable for any loss,

                     reasonably  believed to be genuine and in  accordance  with
                     the  procedures  described in each  prospectus,  as amended
                     from time to time.  Such  procedures  include  recording of
                     telephone instructions,  requesting personal and/or account
                     information  to  verify a  caller's  identity  and  sending
                     written confirmations of transactions.  As a result of this
                     policy, I may bear the risk of any loss due to unauthorized
                     or fraudulent telephone  instructions;  provided,  however,
                     that if the Fund(s) or SDC fail to employ such  procedures,
                     the Fund(s)  and/or SDC may be liable.  TO ELECT  TELEPHONE

          This Statement of Additional Information expands upon and supplements
the information contained in the current Prospectus of Seligman Common Stock
Fund, Inc., (the "Fund") dated May 1, 1995.  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 two classes of shares.  Class A shares may be
purchased at net asset value plus a sales load of up to 4.75%.  Class D shares
may be purchased at net asset value and are subject to a contingent deferred
sales load ("CDSL") of 1% if redeemed within one year.

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

                   INVESTMENT OBJECTIVES, POLICIES AND RISKS

 As stated in the Prospectus, the Fund seeks to produce favorable, but not the
highest, current income and long-term growth of both income and capital value
without exposing capital to undue risk.

Lending of Portfolio Securities.  The Fund may lend portfolio securities to
- -------------------------------                                            
certain institutional borrowers of securities and may invest the cash collateral
and obtain additional income or receive an agreed upon amount of interest from
the borrower.  Loans are subject to termination at the option of the Fund or the
borrower.  The Fund may pay reasonable administrative and custodial fees in
connection with a loan and may pay a negotiated portion of the interest earned
on the cash or equivalent collateral to the borrower or placing broker.  The
Fund does not have the right to vote securities on loan, but would terminate the
loan and regain the right to vote if that were considered important with respect
to the investment.
    
Rights and Warrants.  The Fund may not invest in rights and warrants if, at the
- --------------------                                                           
time of acquisition, the investment in rights and warrants would exceed 5% of
the Fund's net assets, valued at the lower of cost or market.  In addition, no
more than 2% of net assets may be invested in warrants not listed on the New
York or American Stock Exchanges.  For purposes of this restriction, rights and
warrants acquired by the Fund in units or attached to securities may be deemed
to have been purchased without cost.      
    
Foreign Currency Transactions.  A forward foreign currency exchange contract is
- -----------------------------                                                  
an agreement to purchase or sell a specific currency at a future date and at a
price set at the time the contract is entered into.  The Fund will generally
enter into forward foreign currency exchange contracts to fix the US dollar
value of a security it has agreed to buy or sell for the period between the date
the trade was entered into and the date the security is delivered and paid for,
or, to hedge the US dollar value of securities it owns.      
    
 The Fund may enter into a forward contract to sell or buy the amount of a
foreign currency it believes may experience a substantial movement against the
US dollar.  In this case the contract would approximate the value of some or all
of the Fund's portfolio securities denominated in such foreign currency.  Under
normal circumstances, the portfolio manager will limit forward currency
contracts to not greater than 75% of the Fund's portfolio position in any one
country as of the date the contract is entered into.  This limitation will be
measured at the point the hedging transaction is entered into by the Fund.
Under extraordinary circumstances, the Subadviser may enter into forward
currency contracts in excess of 75% of the Fund's portfolio position in any one
country as of the date the contract is entered into.  The precise matching of
the forward contract amounts and the value of securities involved will not
generally be possible since the future value of such securities in foreign
currencies will change as a consequence of market involvement in the value of
those securities between the date the forward contract is entered into and the
date it matures.  The projection of short-term currency market movement is
extremely difficult, and the successful execution of a short-term hedging
strategy is highly uncertain.  Under certain circumstances, the Fund may commit
up to the entire value of its assets which are denominated in foreign currencies
to the consummation of these contracts.  The Subadviser will consider the effect
a substantial commitment of its assets to forward contracts would have on the
investment program of the Fund and its ability to purchase additional
securities.      
    
 Except as set forth above and immediately below, the Fund will also not enter
into such forward contracts or maintain a net exposure to such contracts where
the consummation of the contracts would oblige the Fund to deliver an amount of
foreign currency in excess of the value of the Fund's portfolio securities or
other assets denominated in that currency.  The Fund, in order to avoid excess
transactions and transaction costs, may nonetheless maintain a net exposure to
forward contracts in excess of the value of the Fund's portfolio securities or
other assets denominated in that currency provided the excess amount is
"covered" by cash or liquid, high-grade debt securities, denominated in any
currency, at least equal at all times to the amount of such excess.  Under
normal circumstances, consideration of the prospect for currency parties will be
incorporated into the longer term investment decisions made with regard to
overall diversification strategies.  However, the Subadviser believes that it is
important to have the flexibility to enter into such forward contracts when it
determines that the best interests of the Fund will be served.      
    
 At the maturity of a forward contract, the Fund may either sell the portfolio
security and make delivery of the foreign currency, or it may retain the
security and terminate its contractual obligation to deliver the foreign
currency by purchasing an "offsetting" contract obligating it to purchase, on
the same maturity date, the same amount of the foreign currency.      
    
 As indicated above, it is impossible to forecast with absolute precision the
market value of portfolio securities at the expiration of the forward contract.
Accordingly, it may be necessary for the Fund to purchase additional foreign
currency on the spot market (and bear the expense of such purchase) if the
market value of the security is less than the amount of       

                                      -2-
<PAGE>
 
    
foreign currency the Fund is obligated to deliver and if a decision is made to
sell the security and make delivery of the foreign currency. Conversely, it may
be necessary to sell on the spot market some of the foreign currency received
upon the sale of the portfolio security if its market value exceeds the amount
of foreign currency the Fund is obligated to deliver. However, the Fund may use
liquid, high-grade debt securities, denominated in any currency, to cover the
amount by which the value of a forward contract exceeds the value of the
securities to which it relates.     
    
 If the Fund retains the portfolio security and engages in offsetting
transactions, the Fund will incur a gain or a loss (as described below) to the
extent that there has been movement in forward contract prices.  If the Fund
engages in an offsetting transaction, it may subsequently enter into a new
forward contract to sell the foreign currency.  Should forward prices decline
during the period between the Fund's entering into a forward contract for the
sale of a foreign currency and the date it enters into an offsetting contract
for the purchase of the foreign currency, the Fund will realize a gain to the
extent the price of the currency it has agreed to sell exceeds the price of the
currency it has agreed to purchase.  Should forward prices increase, the Fund
will suffer a loss to the extent the price of the currency it has agreed to
purchase exceeds the price of the currency it has agreed to sell.      
    
 The Fund's dealing in forward foreign currency exchange contracts will be
limited to the transactions described above.  Of course, the Fund is not
required to enter into forward contracts with regard to its foreign currency-
denominated securities and will not do so unless deemed appropriate by the
Subadviser.  It also should be realized that this method of hedging against a
decline in the value of a currency does not eliminate fluctuations in the
underlying prices of the securities.  It simply establishes a rate of exchange
at a future date.  Additionally, although such contracts tend to minimize the
risk of loss due to a decline in the value of a hedged currency, at the same
time, they tend to limit any potential gain which might result from an increase
in the value of that currency.      
    
 Shareholders should be aware of the costs of currency conversion.  Although
foreign exchange dealers do not charge a fee for conversion, they do realize a
profit based on the difference (the "spread") between the prices at which they
are buying and selling various currencies.  Thus, a dealer may offer to sell a
foreign currency to the Fund at one rate, while offering a lesser rate of
exchange should the Fund desire to resell that currency to the dealer.      
    
 Investment income received by the Fund from sources within foreign countries
may be subject to foreign income taxes withheld at the source.  The United
States has entered into tax treaties with many foreign countries which entitle
the Fund to a reduced rate of such taxes or exemption from taxes on such income.
It is impossible to determine the effective rate of foreign tax in advance since
the amounts of the Fund's assets to be invested within various countries is not
known.      

Repurchase Agreements.  The Fund may enter into repurchase agreements with
- ---------------------                                                     
commercial banks and 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 to date has not entered into any repurchase agreements and
has no present intention of doing so 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 with remaining maturities of one year or less at the
date of acquisition are excluded from the calculation.
    
 The Fund's portfolio turnover rates were 57.17% in 1994 and 54.37% in 1993.

    therein.

.   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 other company own in the aggregate more than

.   Write or purchase put, call, straddle or spread options except that the Fund
    may sell covered call options listed on a national securities exchange or

(1)  Based on remuneration received by the Directors of the Fund for the year
ended December 31, 1994.

(2)  As defined in the Fund's Prospectus, the Seligman Group of Investment
Companies consists of seventeen investment companies.

(d)  Deferred.  The total amounts of deferred compensation (including interest)
payable to Messrs. Merow, Pitney and Whitson as of December 31, 1994 were
$69,927, $68,834 and $7,013 respectively.  Mr. Pitney no longer defers current
compensation.
        
 The Fund has a compensation arrangement under which outside directors may elect
to defer receiving their fees.  Under this arrangement, interest is accrued on
the deferred balances.  The annual cost of such interest is included in the
directors' fees and expenses, and the accumulated balance thereof is included in
"Liabilities" in the Fund's financial statements.
        
 Directors and officers of the Fund are also directors or trustees and officers
of some or all of the other investment companies in the Seligman Group.
Directors and officers of the Fund as a group owned directly or indirectly
111,104 shares or less than 1% of the Fund's Class A Capital Stock at March 31,
1995.  As of that date, no Directors or officers owned shares of the Fund's
Class D Capital Stock.

                              MANAGEMENT AND EXPENSES

 As indicated in the Prospectus, under the Management Agreement, dated December
29, 1988, as amended April 10, 1991, subject to the control of the Board of
Directors, the Manager manages the investment of the assets of the Fund,
including making purchases and sales of portfolio securities consistent with the
Fund's investment objectives and policies, and administers its business and
other affairs.  The Manager provides the Fund with such office space,
administrative and other services and executive and other personnel as are
necessary for Fund operations.  The Manager pays all of the compensation of
directors of the Fund who are employees or consultants of the Manager and of the
officers and employees of the Fund.  The Manager also provides senior management
for Seligman Data Corp., the Fund's shareholder service agent.
    
 The Fund pays the Manager a management fee for its services, calculated daily
and payable monthly, based on a percentage of the daily net assets of the Fund.
The method for determining this percentage is set forth in the Appendix to the
Prospectus.  The management fee amounted to $2,676,075 in 1994, $2,645,990 in
1993  and $2,470,823 in 1992 which was equivalent to an annual rate of .49% of
the Fund's average net assets in 1994, .49% in 1993 and .49% in 1992.      

 The Fund pays all its expenses other than those assumed by the Manager,
including brokerage commissions, administration, shareholder services and
distribution fees, fees and expenses of independent attorneys and auditors,
taxes and governmental fees including fees and expenses for qualifying the Fund
and its shares under Federal and state securities laws, 

                                      -8-

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, expenses of shareholders' meetings, expenses of corporate
data processing and related services, shareholder recordkeeping 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 serving 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
administrators, 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, and extraordinary
expenses, exceed 2 1/2% of the first $30,000,000 of average net assets, 2% of
the next $70,000,000 of average net assets, and 1 1/2% thereafter. Such
reimbursement, if any, will be made monthly.      

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

 The Management Agreement was approved by the Board of Directors on September
1988 and by the shareholders at a Special Meeting held on December 16, 1988.
The Management Agreement will continue in effect until December 31 of each year
if (1) such continuance is approved in the manner required by 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 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 corporation.  See the Appendix for further history of the
Manager.
             
 Under the Subadvisory Agreement, dated June 1, 1994, the Subadviser supervises
and directs a portion of the Fund's investment in foreign securities and
Depository Receipts consistent with the Fund's investment objectives, policies
and principles.  For these services, the Subadviser is paid a fee as described
in the Appendix to the Fund's Prospectus.  The Subadvisory Agreement was
approved by the Board of Directors at a meeting held on January 20, 1994 and by
the shareholders of the Fund on May 19, 1994.  The Subadvisory Agreement will
continue in effect until December 31, 1995, and from year to year thereafter if
such continuance is approved in the manner required by the 1940 Act (by a vote
of a majority of the Board of Directors or of the outstanding voting securities
of the Fund and by a vote of a majority of the Directors who are not parties to
the Subadvisory Agreement or interested persons of any such party) and (2) if
the Subadviser shall not have notified the Manager in writing at least 60 days
prior to December 31 of any year that it does not desire such continuance.  The
Subadvisory Agreement may be terminated at any time by the Fund, on 60 days
written notice to the Subadviser.  The Subadvisory Agreement will terminate
automatically in the event of its assignment or upon the termination of the
Management Agreement.      
    
 For the period June 1, 1994 through December 31, 1994, the Subadviser received
a fee of $146,005.     
    
 The Subadviser is a New York general partnership formed by the Manager and
Henderson International, Inc., a controlled affiliate of Henderson
Administration Group plc.   Henderson Administration Group plc, headquartered in
London, is one of the largest independent money managers in Europe.  The Firm
currently manages approximately $18.5 billion in assets and is recognized as a
specialist in global equity investing.      
    
 Officers, directors and employees of the Manager are permitted to engage in
personal securities transactions, subject to the Manager's Code of Ethics (the
"Code").  The Code proscribes certain practices with regard to personal
securities transactions and personal dealings, provides a framework for the
reporting and monitoring of personal securities transactions by the Manager's
Director of Compliance, and sets forth a procedure of identifying, for
disciplinary action, those individuals who violate the Code.  The Code prohibits
each of the officers, directors and employees (including all portfolio managers)
of the Manager from purchasing or selling any security that the officer,
director or employee knows or believes (i) was recommended by the Manager for
purchase or sale by any client, including the Fund, within the preceding two
weeks, (ii) has been reviewed by the Manager for possible purchase or sale
within the preceding two weeks, (iii) is being purchased or      

                                      -9-
<PAGE>
 
    
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 Code also imposes a strict standard
of confidentiality and requires portfolio managers to disclose any interest they
may have in the securities or issuers that they recommend for purchase by any
client.      
    
 The Code also prohibits (i) each portfolio manager or member of an investment
team from purchasing or selling any security within seven calendar days of the
purchase or sale of the security by a client's account (including investment
company accounts) for which the portfolio manager or investment team manages and
(ii) each employee from engaging in short-term trading (a purchase and sale or
vice-versa within 60 days).  Any profit realized pursuant to either of these
prohibitions must be disgorged.     
    
 Officers, directors and employees are required, except under very limited
circumstances, to engage in personal securities transactions through the
Manager's order desk.  The order desk maintains a list of securities that may
not be purchased due to a possible conflict with clients.  All officers,
directors and employees are also required to disclose all securities
beneficially owned by them on December 31 of each year.      

          ADMINISTRATION, SHAREHOLDER SERVICES AND DISTRIBUTION PLAN

 As indicated in the Prospectus, the Fund has adopted an Administration,
Shareholder Services and Distribution Plan for each Class (the "Plan") in
accordance with Section 12(b) of the Act and Rule 12b-1 thereunder.
    
 The Plan was approved on July 16, 1992 by the Board of Directors of the Fund,
including a majority of the Directors who are not "interested persons" (as
defined in the Act) and who have no direct or indirect financial interest in the
operation of the Plan or in any agreement related to the Plan (the "Qualified
Directors") and was approved by shareholders of the Fund at a Special Meeting of
Shareholders held on November 23, 1992.  The Plan became effective in respect of
the Class A shares on January 1, 1993.  The Plan was approved in respect of the
Class D shares on March 18, 1993 by the Board of Directors of the Fund,
including a majority of the Qualified Directors, and became effective with
respect to the Class D shares on May 1, 1993.  The Plan will continue in effect
through December 31 of each year so long as such continuance is approved by a
majority vote of both the Directors and the Qualified Directors of the Fund,
cast in person at a meeting called for the purpose of voting on such approval.
The Plan may not be amended to increase materially the amounts payable to
Service Organizations with respect to a Class without the approval of a majority
of the outstanding voting securities of the Class and no material amendment to
the Plan may be made except by a majority of both the Directors and 
Qualified Directors.      

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

                              PORTFOLIO TRANSACTIONS
    
 The Management and Subadvisory Agreements recognize that in the purchase and
sale of portfolio securities the Manager and Subadviser will seek the most
favorable price and execution, and, consistent with that policy, may give
consideration to the research, statistical and other services furnished by
brokers or dealers to the Manager and Subadviser for their use, as well as to
the general attitude toward and support of investment companies demonstrated by
such broker 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 security and economic analysis
although the use of such brokers may result in a higher brokerage charge to the
Fund that 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.

                                      -10-
<PAGE>
 
    
 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.
     
 Brokerage commissions for the last three fiscal years are set forth in the
following table:

     Securities, Inc. acted as broker was 16.4% of the total dollar amount of
     all commission transactions in 1993 and 50.0% in 1992.  The Board 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 (exclusive of option and
     option-related transactions) at commissions 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
     Corporation and its other clients.

CLASS A SHARES - REDUCED SALES LOADS

Reductions Available.  Shares of any future Seligman Funds sold with a sales
- --------------------                                                        
load in a continuous offering will be eligible for the following 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 funds in
the Seligman Group which are sold with a sales load, reaches levels indicated in
the sales load schedule set forth in the Prospectus.

 The Right of Accumulation allows an investor to combine the amount being
invested in Class A shares of the Fund and shares of Seligman Capital Fund,
Seligman Communications and Information Fund, Seligman Frontier Fund, Seligman
Growth Fund, Seligman Henderson Global Fund Series, Seligman High Income Fund
Series, Seligman Income Fund, Seligman New Jersey Tax-Exempt Fund, Seligman
Pennsylvania Tax-Exempt Fund Series, Seligman Tax-Exempt Fund Series, or
Seligman Tax-Exempt Series Trust sold with a sales load with the total net asset
value of shares of those Mutual Funds already owned that were sold with a sales
load and the total net asset value of shares of Seligman Cash Management Fund
which were acquired through an exchange of shares of another mutual fund in the
Seligman Group on which there was a sales load at the time of purchase to
determine reduced sales loads in accordance with the schedule in the Prospectus.
The value of the shares owned, including the value of shares of Seligman Cash
Management Fund acquired in an exchange of shares of another mutual fund in the
Seligman Group on which there was a sales load at the time of purchase will be
taken into account in orders placed through a dealer, however, only if Seligman
Financial Services, Inc. is notified by an investor or dealer of the amount
owned at the time your purchase is made and is furnished sufficient information
to permit confirmation.

 A Letter of Intent allows an investor to purchase Class A shares over a 13-
month period at reduced sales loads in accordance with the schedule in the
Prospectus, based on the total amount of Class A shares of the Fund that the
letter states the investor intends to purchase plus the total net asset value of
shares sold with a sales load of Seligman Capital Fund, Seligman Communications
and Information Fund, Seligman Frontier Fund, Seligman Growth Fund, Seligman
Henderson Global Fund Series, Seligman High Income Fund Series, Seligman Income
Fund, Seligman New Jersey Tax-Exempt Fund, Seligman Pennsylvania Tax-Exempt Fund
Series, Seligman Tax-Exempt Fund Series, or Seligman Tax-Exempt Series Trust
already owned and the total net asset value of shares of Seligman Cash
Management Fund which were acquired through an exchange of shares of another
mutual fund in the Seligman Group on which there was a sales load at the time of
purchase.  Reduced sales loads also may apply to purchases made within a 13-
month period starting up to 90 days before the date of execution of a letter of
intent.  For more information concerning the terms of the letter of intent, see
"Terms and Conditions - Letter of Intent - Class A Shares Only" accompanying the
account application in the Prospectus.

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

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

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

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

Eligible Employee Benefit Plans.  The term "eligible employee benefit plan"
- -------------------------------                                            
means any plan or arrangement, whether or not tax qualified, which provides for
the purchase of Fund shares.  The term "participant account plan" means any
"eligible employee benefit plan" where (i) the Fund shares are purchased through
payroll deductions or otherwise by a fiduciary or other person for the account
of participants who are employees (or their spouses) of an employer and (ii) a
separate Open 

                                      -12-
<PAGE>
 
Account is maintained in the name of such fiduciary or other person for the
account of each participant in the plan (such as a payroll deduction IRA
program).

 The table of sales loads in the Prospectus applies to sales to "eligible
employee benefit plans," except that the Fund may sell shares at net asset value
to "eligible employee benefit plans," of employers who have at least 2,000 U.S.
employees to whom such plan is made available or, regardless of the number of
employees, if such plan is established or maintained by any dealer which has a
sales agreement with Seligman Financial Services, Inc.  Such sales must be made
in connection with a payroll deduction  system of plan funding or other systems
acceptable to Seligman Data Corp., the Fund's shareholder 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 Seligman Financial
Services, Inc.

Payment in Securities.  In addition to cash, the Fund may accept securities in
- ---------------------                                                         
payment for Fund shares sold at the applicable public offering price (net asset
value plus any applicable sales load) although the Fund does not presently
intend to accept securities in payment for Fund shares.  Generally, the Fund
will only consider accepting securities (l) to increase its holdings in a
portfolio security, or (2) if the Manager determines that the offered securities
are a suitable investment for the Fund and in a sufficient amount for efficient
management.  Although no minimum has been established, it is expected that the
Fund would not accept securities with a value of less than $100,000 per issue in
payment for shares.  The Fund may reject in whole or in part offers to pay for
Fund shares with securities, may require partial payment in cash for applicable
sales loads, and may discontinue accepting securities as payment for Fund shares
at any time without notice.  The Fund will not accept restricted securities in
payment for shares.  The Fund will value accepted securities in the manner
provided for valuing portfolio securities of the Fund.  Any securities 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 evidences
by a listing on the American Stock Exchange, the New York Stock Exchange or
NASDAQ.
    
Further Types of Reductions.  Class A shares may be issued without a sales load
- ---------------------------                                                    
in connection with the acquisition of cash and securities owned by other
investment companies and personal holding companies, to financial institution
trust departments, to registered investment advisers exercising discretionary
investment authority with respect to the purchase of Fund shares, or pursuant to
sponsored arrangements with organizations which make recommendations to, or
permit group solicitation of, its employees, members or participants in
connection with the purchase of shares of the Fund, to separate accounts
established and maintained by an insurance company which are exempt from
registration under Section 3(c)(11) of the Investment Company Act of 1940, to
registered representatives (and their spouses and minor children) and employees
of any dealer that has a sales agreement with SFSI, to shareholders of mutual
funds with investment objectives and policies similar to the Fund's who purchase
shares with redemption proceeds of such funds and to certain unit investment
trusts as described in the Prospectus.      

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

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

                              DISTRIBUTION SERVICES

 The Fund and Seligman Financial Services, Inc. ("SFSI") are parties to a
Distributing Agreement, dated January 1, 1993.  SFSI, an affiliate of the
Manager, acts as general distributor of the shares of the Fund and of the other
mutual funds

                                      -13-
<PAGE>
 
    
in the Seligman Group. As general distributor of the Fund's Capital Stock, SFSI
allows concessions to all dealers, as indicated in the Prospectus. Pursuant to
agreements with the Fund, certain dealers may also provide sub-accounting and
other services for a fee. SFSI receives the balance of sales loads and any CDSLs
paid by investors. The balance of sales loads paid by investors and received by
SFSI in respect of Class A shares amounted to $46,173 in 1994, after allowance
of $355,656 as concessions to dealers; $38,939 in 1993, after allowance of
$302,241 as concessions to dealers; and $32,080 in 1992, after allowance of
$259,262 as concessions to dealers. For the year ended December 31, 1994, SFSI
retained CDSL charges from Class D shares amounting to $ 3,862; and $1,072 for
the period May 3, 1993 through December 31, 1993.      

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

                                   VALUATION
    
 Net asset value per Fund share is determined as of the close of trading on the
New York Stock Exchange, (currently 4:00 p.m. Eastern time), each day that the
New York Stock Exchange is open. The New York Stock Exchange is currently closed
on New Year's Day, Presidents' Day, Good Friday,  Memorial Day, Independence
Day, Labor Day, Thanksgiving Day and Christmas Day.  The net asset value of
Class D shares will generally be lower than the net asset value of Class A
shares as a result of the larger distribution fee with respect to Class D
shares.      
    
 The net asset value per share is determined separately for each class of
shares.  Portfolio securities, including open short positions and options
written, are valued at the last sale price on the securities exchange or
securities market on which such securities primarily are traded.  Securities
traded on a foreign exchange or over-the-counter market are valued at the last
sales price on the primary exchange or market on which they are traded.  United
Kingdom securities and securities for which there are no recent sales
transactions are valued based on quotations provided by primary market makers in
such securities.  Any securities for which recent market quotations are not
readily available, 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 on an amortized cost basis based on
the value of such date unless the Board determines that this amortized cost
value does not represent fair market value.  Expenses and fees, including the
investment management fee, are accrued daily and taken into account for the
purpose of determining the net asset value of Fund shares.  Premiums received on
the sale of call options will be included in the net asset value, and the
current market value of the options sold by the Fund will be subtracted from net
asset value.      

 Generally, trading in foreign securities, as well as US Government securities,
money market instruments and repurchase agreements, is substantially completed
each day at various times prior to the close of the NYSE.  The values of such
securities used in computing the net asset value of the shares of the Fund are
determined prior to the close of the NYSE, which will not be reflected in the
computation of net asset value.  If during such periods events occur which
materially affect the value of such securities, the securities will be valued at
their fair market value as determined in accordance with procedures approved by
the Board of Directors.

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

                                  PERFORMANCE
    
 The Fund's average annual total returns of Class A shares for the one-year,
five-year and ten-year periods ended on December 31, 1994 were (6.54)%, 8.24%
and 12.76% respectively.  These amounts were computed by assuming a hypothetical
initial payment of $1,000, subtracting the maximum sales load of $47.50 (4.75%
of public offering price) and assuming that all of the dividends and
distributions by the Fund over the relevant time period were reinvested.  It was
then assumed that at the end of these periods, the entire amount was redeemed.
The average annual total return was then calculated by calculating the annual
rate required for the initial payment to grow to the amount which would have
been received upon redemption (i.e., the average annual compound rate of
return).  The average annual total returns for Class D      

                                      -14-
<PAGE>
 
    
shares of the Fund for the year ended December 31, 1994 and since inception
through December 31, 1994 were (4.14)% and 3.30%, respectively. This amount was
computed assuming a hypothetical initial payment of $1,000 and that all of the
dividends and distributions paid by the Fund's Class D shares, were reinvested
over the relevant time period. For the one-year period ended December 31, 1994
it was then assumed that at the end of the period, the entire amount was
redeemed, subtracting the applicable 1% CDSL.      
    
 Table A below illustrates the total return (income and capital) on Class A
shares of the Fund with dividends invested and gain distributions taken in
shares.  It shows that a $1,000 investment in Class A shares, assuming payment
of the 4.75% sales load, made on January 1, 1985 had a value of $3,323 on
December 31, 1994, resulting in an aggregate total return of 232.27%.  Table B
illustrates the total return (income and capital) on Class D shares of the Fund
with dividends invested and gain distributions taken in shares.  It shows that a
$1,000 investment in Class D shares made on May 3, 1993 (commencement of
offering of Class D shares) had a value of $1,056 on December 31, 1994 resulting
in an aggregate total return of 5.55%.  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.

1 For the ten years ended December 31, 1994; and from commencement of offering
  of Class D shares on May 3, 1993.      

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

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

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

 The total return and average annual total return of the Class A shares quoted
from time to time through December 31, 1992 does not reflect the deduction of
the administration, shareholder services and distribution fee, effective January
1, 1993; and through April 10, 1991 also does not reflect the increased
management fee approved by shareholders on April 10, 1991, which fees if
reflected would reduce the performance quoted.

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

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

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

To the Shareholders
- --------------------------------------------------------------------------------
 
     We are pleased to report Seligman Common Stock Fund's long-term investment
results, portfolio holdings, and audited financial statements at December 31,
1994.
     For your Fund's Class A shares, net asset value per share was $12.12 at
December 31, compared to $13.14 at September 30, and $13.47 a year ago. For your
Fund's Class D shares, net asset value per share was $12.07 at December 31,
compared to $13.11 at September 30, and $13.46 a year ago. For both Class A and
D shares, the change in the net asset values is partly caused by the deduction
of the $0.72 per share capital gain payment made on December 20 to Shareholders
of record December 13.
     On December 20, your Fund paid a fourth quarter dividend to shareholders of
record December 13. Class A shareholders were paid $0.10 per share, bringing the
total dividends for the year to $0.37 per share. Class D shareholders were paid
$0.08 per share, bringing the total dividends for the year to $0.23 per share.
     For your Fund's Class A shares, total return was -1.47% for the three 
months and -1.89% for the 12 months ended December 31. For your Fund's Class D
shares, total return was -1.79% and -3.24%, respectively, for the same periods.
This compares to the Standard & Poor's 500 Composite Stock Price Index's total
return of -0.02% for the three months and 1.32% for the 12 months ended December
31. (Total return reflects change in net asset value and assumes any
distributions paid within the period are reinvested in additional shares. Class
A returns do not, however, reflect the effect of the maximum initial sales
charge of 4.75%, and Class D returns do not reflect the effect of the 1%
contingent deferred sales load.)
     While your Fund's performance was less favorable in 1994, its longer-term
performance remains strong. Please refer to page 3 for a discussion with your
Portfolio Managers about your Fund's performance in 1994, followed by the chart
and table that analyze longer-term performance.
     Looking back on 1994, the one generalization that can be made with
confidence is that it was a turbulent and trying year for equity and bond
investors alike. The Federal Reserve Board exhibited an aggressive stance
against inflation, putting through six short-term interest rate increases by the
end of the year. This caused an upheaval in the bond market, with yields
increasing and bond prices spiraling lower--an event in the financial markets
unmatched in magnitude since 1973-74. The equity market remained hostage to the
bond market and demonstrated lackluster performance for the year.
     The U.S. economy continued to grow at a modest yet controlled pace,
accompanied by corporate news of solid growth and strong earnings. This economic
news, although positive, caused the underlying question to remain: Will the
economy overheat, opening the door to increased inflation? We don't believe so.
     We believe an economic slowdown is close at hand. In March of 1995, the
current growth cycle will mark its fourth year. The consumer has both increased
debt as a percentage of income and drawn down savings--suggesting nearer-term
caution after a stronger-than-expected pattern of spending in 1994. We also
believe that inflation will remain under control in light of intense global
competition, low unit labor costs, and an aging population that should favor
saving over spending. Job creation remains robust despite gains in productivity,
and U.S. competitiveness in world markets is likely to be enhanced under
G.A.T.T.--General Agreement on Tariffs and Trade.

Annual Performance Overview

regarding Seligman Common Stock Fund, and a comparison chart of your Fund's
performance against the Standard & Poor's 500 Composite Stock Price Index and
the Lipper Growth & Income Fund Average.
 
Your Portfolio Managers
[photograph]
 
Charles C. Smith, Jr. is a Managing Director of J. & W. Seligman & Co.
Incorporated and Portfolio Manager of Seligman Common Stock Fund and Seligman
Income Fund. Mr. Smith joined Seligman in 1985 as Vice President, Investment
Officer. He was promoted to Senior Vice President, Senior Investment Officer in
August 1992, and to Managing Director in January 1994. Stacey G. Navin, Vice
President of J. & W. Seligman & Co. Incorporated, serves as Co-Portfolio Manager
of Seligman Common Stock Fund and Seligman Income Fund. She spent 1994 with
Seligman Henderson Co. in London and will continue to do so in 1995 to
specifically focus on the international investments in the portfolio. Mr. Smith
is supported by a group of investment professionals dedicated to the growth and
income investment discipline, and to the objectives of Seligman Common Stock
Fund.
 
Iain C. Clark, Chief Investment Officer of Seligman Henderson Co., is
responsible for the investment activities of Seligman Common Stock Fund's
Subadviser, Seligman Henderson Co. Mr. Clark is also head of International
Investments for, and a Director of, Henderson Administration Group plc, an
investment manager in London, England. He has been with Henderson since 1985.
 
Economic Factors Affecting Seligman Common Stock Fund
 
"The rise in short-term interest rates and investors' concerns over an increased
rate of future inflation had a tremendous effect on both the equity and bond
markets in the U.S. Higher U.S. interest rates also negatively affected most
stock markets around the world. However, at the same time, the U.S. Dollar
weakened against many main currencies, particularly in Europe and Japan, thus
mitigating some of the stock markets' falls. Overall, though, these conditions
made 1994 a challenging year for investors."
 
Your Manager's Investment Strategy
 
"While many investors focused on issues with attractive short-term momentum,
such as cyclical and technology issues, your Fund continued to maintain a
broadly diversified portfolio of quality companies with strong long-term
prospects for earnings growth. We believe our strategy of holding a well-rounded
list of companies in many industry groups should continue to benefit the
portfolio in the years ahead. In the international portion of the portfolio we
significantly increased the diversification, both by country and by the number
of holdings. In the third quarter, the largest portion of the investments were
in Mexico and Hong Kong. Later in the year, however, the weightings were
significantly reduced and investments were made in Continental Europe and in a
broader range of countries in the Pacific."

                                  (continued)

Annual Performance Overview (continued)
- -------------------------------------------------------------------------------

Individual Sector Performance
 
"While cyclical issues such as chemical and technology companies did
particularly well, the Fund's best performing stocks were the restructuring
companies such as IBM and U.S. Shoe. Conversely, both financial stocks, in
particular bank issues, and convertible securities had a difficult time in 1994
due to their inherent sensitivity to interest rate changes.
 
"Internationally, there was no particular `sector theme,' as the investments
covered a broad range of issues. The Fund was able to take advantage of a number
of attractively priced new issues such as Tele Danmark, Autoliv, Liberty Life,
and Indosat, all of which present opportunities for strong long-term
investments."
 
Looking Ahead
 
"With the prospect of slowing economic growth in 1995, stock selection will
continue to be central to good near-term performance. Within the international
portion of the portfolio, we may increase the Fund's low weighting in Japan as
the economic activity picks up following the Kobe earthquake. Overall, we
believe that economic growth should continue to improve, with inflation rising
only slightly, which should provide a positive backdrop for equity markets
around the world. In 1995, we will continue to focus on identifying companies
with strong long-term earnings and growth potential as a means of achieving good
capital appreciation and dividend growth."

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 period are invested in
additional shares. The investment return and principal value of an investment
will fluctuate so that shares, if redeemed, may be worth more or less than 
their original cost. Past performance is not indicative of future investment 
results.

Notes to Financial Statements
- --------------------------------------------------------------------------------
 
1. Effective May 3, 1993, Seligman Common Stock Fund, Inc. (the "Fund") began
offering two classes of shares. All shares existing prior to May 3, 1993, have
been classified as Class A shares. Class A shares are sold with an initial sales
charge of up to 4.75% and a continuing service fee of up to 0.25% on an annual
basis. Class D shares are sold without an initial sales charge but are subject
to a higher distribution fee and a contingent deferred sales load ("CDSL") of 1%
imposed on certain redemptions made within one year of purchase. The two classes
of shares represent interests in the same portfolio of investments, have the
same rights and are generally identical in all respects except that each class
bears its separate distribution and certain class expenses and has exclusive
voting rights with respect to any matter to which a separate vote of any class
is required.

2. Significant accounting policies followed, all in conformity with generally  
accepted accounting principles, are given below: a. Investments in convertible
securities and 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. The books and records of the Fund are maintained in U.S. dollars. The
   market value of investment securities and other assets and liabilities
   denominated in foreign currencies are translated into U.S. dollars at the
   closing daily rate of exchange as reported by a pricing service. Purchases
   and sales of investment securities, income, and expenses are translated into
   U.S. dollars at the rate of exchange prevailing on the respective dates of
   such transactions.
   The Fund separates that portion of the results of operations resulting from
   changes in the foreign exchange rates from the fluctuations arising from
   changes in the market prices of securities held in the portfolio. Similarly,
   the Fund separates the effect of changes in foreign exchange rates from the
   fluctuations arising from changes in the market prices of portfolio
   securities sold during the period.
c. 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.
d. 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.
e. All income, expenses (other than class-specific expenses), and realized and
   unrealized gains or losses are allocated daily to each class of shares based
   upon the relative proportion of the value of shares outstanding of each
   class. Class-specific expenses, which include distribution and service fees
   and any other items that can be specifically attributed to a particular
   class, are charged directly to such class.
f. The treatment for financial statement purposes of distributions made during
   the year from net investment income or net realized gain 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 and the recharacter-
   ization of foreign exchange gains or losses to either ordinary income or
   realized capital gain for federal income tax purposes. Where such differences
   are permanent in nature, they are reclassified in the components of net
   assets based on their ultimate characterization for federal income tax
   purposes. Any such reclassification will have no effect on net assets,
   results of operations, or net asset value per share of the Fund.
3. Purchases and sales of portfolio securities, excluding short-term 
investments, for the year ended December 31, 1994, amounted to $302,384,215 and
$300,438,815, respectively.
   At December 31, 1994, the cost of investments for federal income tax purposes
was substantially the same as the cost for financial reporting purposes, and the
tax basis gross unrealized appreciation and depreciation of portfolio
securities, including the effects of foreign currency transactions, amounted to
$118,416,221 and $23,382,914, respectively.

4. J. & W. Seligman & Co. Incorporated (the "Manager") manages the affairs of
the Fund and provides the necessary personnel and facilities. Compensation of
all officers of the Fund, all directors of the Fund who are employees or
consultants of the Manager, and all personnel of the Fund and the Manager is
paid by the Manager. The Manager receives a fee, calculated daily and payable
monthly, equal to a per annum percentage of the Fund's daily net assets. The
management fee rate is calculated on a sliding scale of 0.50% to 0.44%, based on
average daily net assets of all the investment companies managed by the Manager.
The management fee for the year ended December 31, 1994, was equivalent to an
annual rate of 0.49% of the average daily net assets of the Fund. Effective June
1, 1994, Seligman Henderson Co. (the "Subadviser"), a 50% owned affiliate of the
Manager, is entitled to a portion of the Manager's fee for acting as subadviser
for certain of the international investments of the Fund.
     Seligman Financial Services, Inc. (the "Distributor"), agent for the
distribution of Fund shares and an affiliate of the Manager, received
commissions of $46,173 from sales of Class A shares, after concessions of
$355,656 paid to dealers.
     Effective January 1, 1993, the Fund adopted an Administration, Shareholder
Services and Distribution Plan (the "Plan") with respect to Class A shares under
which service organizations can enter into agreements with the Distributor and
receive a continuing fee of up to 0.25% on an annual basis, payable quarterly,
of the average daily net assets of the Class A shares attributable to the
particular service organizations for providing personal services and/or the
maintenance of shareholder accounts. The Distributor charges such fees to the
Fund pursuant to the Plan. For the year ended December 31, 1994, fees incurred
aggregated $703,165, or 0.14% per annum of the average daily net assets of Class
A shares.
     Effective May 3, 1993, the Fund adopted a Plan with respect to Class D
shares under which service organizations can enter into agreements with the
Distributor and receive a continuing fee for providing personal services and/or
the maintenance of shareholder accounts of up to 0.25% on an annual basis of the
average daily net assets of the Class D shares for which the organizations are
responsible, and fees for providing other distribution assistance of up to 0.75%
on an annual basis of such average daily net assets. Such fees are paid monthly
by the Fund to the Distributor pursuant to the Plan. For the year ended December
31, 1994, fees paid amounted to $102,751, or 1% per annum of the average daily
net assets of Class D shares.
     The Distributor is entitled to retain any CDSL imposed on certain
redemptions occurring within one year of purchase. For the year ended December
31, 1994, such charges amounted to $3,862.
     Seligman Data Corp., owned by the Fund and certain associated investment
companies, charged the Fund at cost $837,197 for shareholder account services.
The Fund's investment in Seligman Data Corp. is recorded at a cost of $22,506.
     Certain officers and directors of the Fund are officers or directors of the
Manager, the Subadviser, the Distributor, and/or Seligman Data Corp. Fees of
$28,000 were incurred by the Fund for legal services of Sullivan & Cromwell, a
member of which firm is a director of the Fund.
     The Fund has a compensation arrangement under which directors who receive
fees may elect to defer receiving such fees. Interest is accrued on the deferred
balances. The annual cost of such fees and interest is included in directors'
fees and expenses, and the accumulated balance thereof at December 31, 1994, of
$145,774 is included in other liabilities. Deferred fees and the related accrued
interest are not deductible for federal income tax purposes until such amounts
are paid. 5. Class-specific expenses charged to Class A and Class D during the
year ended December 31, 1994, which are included in the corresponding captions
of the Statement of Operations, were as follows:

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

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

We have audited the accompanying statement of assets and liabilities, including

changes in net assets for each of the years in the two-year period then ended,
and the financial highlights for the periods presented. These financial
statements and financial highlights are the responsibility of the Fund's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of
December 31, 1994 by correspondence with the Fund's custodians 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 Common
Stock Fund, Inc. as of December 31, 1994, the results of its operations, the
changes in its net assets and the financial highlights for the respective stated
periods, in conformity with generally accepted accounting principles.

     any other expenses of the Corporation, including, but not limited to,
     direct charges relating to the purchase and sale of portfolio securities,

     such as litigation expenses.

I.   Compensation.

     I.    As compensation for the services performed and the facilities and
           personnel provided by the Manager pursuant to Section 1, the
           Corporation will pay to the Manager promptly after the end of each
           month a fee, calculated on each day during such month, equal to the
           Applicable Percentage of the daily net assets of the Corporation at
           the close of business on the previous business day.

     I.    As used herein.

           I.   The term "Applicable Percentage" means the amount (expressed as
                a percentage and rounded to the nearest one millionth of one
                percent) obtained by dividing (i) the Fee Amount by (ii) the Fee
                Base.

           I.   The term "Fee Amount" means the sum of the following:

           .50 of 1% on an annual basis of the first $4,000,000,000 of Fee Base,
           .48 of 1% on an annual basis of the next $2,000,000,000 of Fee Base,
           .46 of 1% on an annual basis of the next $2,000,000,000 of Fee Base,
           and
           .44 of 1% on an annual basis of Fee Base in excess of $8,000,000,000.

           I.   The term "Fee Base" as of any day means the sum of the net
                assets at the close of business on the previous day of each of
                the investment companies registered under the Act for which the
                Manager or any affiliated company acts as investment adviser or
                manager (including the Corporation).

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

I.    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.
<PAGE>
 
                                      -3-

     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 to 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.

I.    Term of Agreement.  This Agreement shall continue in full force and effect
      until December 29, 1992 and from year to year thereafter if such
      continuance is approved in the manner required by the Act and if the
      Manager shall not have notified the Corporation in writing at least 60
      days prior to December 29 or prior to December 29 of any year thereafter
      that it does not desire such continuance.  This Agreement may be
      terminated at any time, without payment of penalty by the Corporation, on
      60 days' written notice to the Manager by vote of the Board of Directors
      of the Corporation or by vote of a majority of the outstanding voting
      securities of the Corporation (as defined by the Act).  This Agreement
      shall automatically terminate in the event of its assignment (as defined
      by the Act).

I.    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.

                       Seligman Common Stock Fund, Inc.


SUBADVISORY AGREEMENT, dated as of May 19, 1994 between J. & W. SELIGMAN & CO.

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

parties hereto agree as follows:

1.  Duties of the Subadviser.  The Subadviser will provide the Fund with

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

of the 1940 Act and other applicable law.

Subject to Section 36 of the 1940 Act, the Subadviser shall not be liable to the
Fund for any error of judgment or mistake of law or for any loss arising out of
any investment or for any act or omission in the management of the Fund and the
performance of its duties under this Agreement except for willful misfeasance,
bad faith or gross negligence in the performance of its duties or by reason of
reckless disregard of its obligations and duties under this Agreement.

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

3.  Compensation

    (a)  As compensation for the services performed and the facilities and
         personnel provided by the Subadviser pursuant to Section 1, the Manager
         will pay to the Subadviser each month a fee, equal to the Applicable
         Percentage of the average monthly Net Qualifying Assets of the Fund.
<PAGE>
 
    (b)  As used herein:

         (1)  The term "Applicable Percentage" means the amount (expressed as a
              percentage and rounded to the nearest one millionth of one
              percent) obtained by dividing (i) the Fee Amount by (ii) the Fee
              Base.

         (2)  The term "Fee Amount" means the sum of the following:

              .50 of 1% on an annual basis of the first $4,000,000,000 of Fee
              Base,
              .48 of 1% on an annual basis of the next $2,000,000,000 of Fee
              Base,
              .46 of 1% on an annual basis of the next $2,000,000,000 of Fee
              Base,
              .44 of 1% on an annual basis of Fee Base in excess of
              $8,000,000,000.

         (3)  The term "Fee Base" as of any day means the sum of the net assets
              at the close of business on the previous day of each of the
              investment companies registered under the 1940 Act for which the
              Manager or any affiliated company acts as investment adviser or
              manager (including the Fund).

         (4)  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 
<PAGE>
 
practice. It is understood that the services provided by such brokers may be
useful to the Subadviser in connection with its services to other clients as
well as the Fund.

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

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

5.  Term of Agreement.  This Agreement shall continue in full force and effect
until December 31, 1995, and from year to year thereafter if such continuance is
approved in the manner  required by the 1940 Act, and if the Subadviser shall
not have notified the Manager in writing at least 60 days prior to such date or
prior to December 31 of any year thereafter that it does 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.
