Re:      Seligman Henderson Global Fund Series, Inc. (the "Fund")
         Post-Effective Amendment No. 28
         File No. 33-44186 and 811-6485

Dear Sirs:

         Following is the Edgarized filing of Post-Effective Amendment No. 28 to
the Registration Statement on Form N-1A of the Fund, filed pursuant to a request
granted under Rule 485(b)(I)(vii) of the Securities Act of 1933 ("1933 Act"),
and Amendment No. 30 under the Investment Company Act of 1940. The filing has
been marked to show changes from Post-Effective Amendment No. 27, filed on March
1, 1999.

          This post-effective amendment is being filed for the purpose of adding
a new class of shares (Class C shares) and contains substantially identical
revisions to those contained in Post-Effective Amendment No. 27 to the
Registration Statement of Seligman Frontier Fund, Inc. (File No. 2-92487), which
was filed with the Securities and Exchange Commission under Rule 485(a)(1) on
April 1, 1999 (Accession Number: 0000930413-99-000490).

         Certain other non-material changes have also been made as the Fund
deemed appropriate. As such, this Post-Effective Amendment contains no
disclosure that would render it ineligible to become effective pursuant to Rule
485(b) of the 1933 Act.

         If there are any questions or comments, please call the undersigned at
(212) 850-1426.

                                                    Very truly yours,

                                                    /s/ Maureen A. Coleman

THE FUNDS

SELIGMAN HENDERSON INTERNATIONAL FUND

INVESTMENT OBJECTIVE/PRINCIPAL STRATEGIES
The International Fund's objective is long-term capital appreciation.

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

The Fund invests primarily in equity securities of non-US issuers. The Fund may
invest in any country; however, it typically will not invest in the US. It
generally invests in several countries in different geographic regions.

The Fund generally invests in the common stock of medium- to large-sized
companies in the principal international markets. However, it may also invest in
companies with a lower market capitalization or in smaller regional or emerging
markets.

The Fund uses a top-down investment style. This means the investment manager
concentrates first on regional and country allocations, then on industry
sectors, followed by fundamental analysis of individual companies. The Fund's
investments are allocated among geographic regions or countries based on such
factors as:
         o Relative economic growth potential of the various economies and
           securities markets
         o Political, financial, and social conditions influencing investment
           opportunities
         o Investor sentiment
         o Prevailing interest rates and expected levels of inflation
         o Market prices relative to historic averages

In selecting individual securities, the investment manager looks to identify
companies that it believes display one or more of the following:
         o Attractive valuations relative to earnings forecasts or other
           valuation criteria (e.g., return on equity)
         o Quality management and equity ownership by executives
         o Unique competitive advantages (e.g., market share, proprietary
           products)
         o Market liquidity o Potential for improvement in overall operations

The Fund generally sells a stock if the investment manager believes its target
price has been reached, its earnings are disappointing, its revenue growth has
slowed, or its underlying fundamentals have deteriorated. The Fund may also sell
a stock if the investment manager believes that negative country or regional
factors may affect a company's outlook, or to meet cash requirements.

The Fund may invest in all types of securities, many of which will be
denominated in currencies other than the US dollar. The securities may be listed
on a US or foreign stock exchange or traded in US or foreign over-the-counter
markets. The Fund normally concentrates its investments in common stocks;
however, it may invest in other types of equity securities, including securities
convertible into or exchangeable for common stock, depositary receipts, and
rights and warrants to purchase common stock. The Fund also may invest up to 25%
of its assets in preferred stock and investment grade or comparable quality debt
securities.


                                       2
<PAGE>



The Fund may invest up to 15% of its net assets in illiquid securities (i.e.,
securities that cannot be readily sold), and may from time to time enter into
forward foreign currency exchange contracts in an attempt to manage the risk of
adverse changes in currencies. The Fund may also purchase put options (which
gives the Fund the right to sell an underlying security at a particular price
during a fixed period) in an attempt to hedge against a decline in the price of
securities it holds in its portfolio. Foreign currency forward contracts and put
options on securities may not be available to the Fund on reasonable terms in
many situations and the Fund may frequently choose not to enter into such
contracts or purchase such options even when they are available. The Fund may,
from time to time, take temporary defensive positions that are inconsistent with
its principal strategies in seeking to minimize extreme volatility caused by
adverse market, economic, or other conditions. This could prevent the Fund from
achieving its objective.

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


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


PRINCIPAL RISKS


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

Investing in securities of foreign issuers involves risks not associated with US
investments, including settlement risks, currency fluctuation, local withholding
and other taxes, different financial reporting practices and regulatory
standards, high costs of trading, changes in political conditions,
expropriation, investment and repatriation restrictions and settlement and
custody risks.


The Fund seeks to limit the risk of investing in foreign securities by
diversifying its investments among different regions and countries.
Diversification reduces the effect events in any one country will have on the
Fund's entire investment portfolio. However, a decline in the value of the
Fund's investments in one country may offset potential gains from investments in
another country.


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


To the extent the Fund invests some of its assets in higher-risk securities,
such as illiquid securities, it may be subject to higher price volatility.


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


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

SELIGMAN HENDERSON INTERNATIONAL FUND

PAST PERFORMANCE


The Fund offers four Classes of shares. The information below provides some
indication of the risks of investing in the Fund by showing how the performance
of Class A shares has varied year to year, as well as how the performance of
each Class (except Class C) compares to two widely-used measures of performance.
Class C is a new class of shares, effective June 1, 1999, so no performance
information is available. Although the Fund's fiscal year ends on October 31,
the performance is provided on a calendar year basis to assist you in comparing
the returns of the Fund with the returns of other mutual funds. How the Fund has
performed in the past, however, is not necessarily an indication of how the Fund
will perform in the future. Total returns will vary between each Class of shares
due to the different fees and expenses of each Class. The Class A annual total
returns presented in the bar chart do not reflect the effect of any sales
charges. If these charges were included, the returns would be less. The average
annual total returns presented in the table below the chart do reflect the
effect of the applicable sales charges. Both the bar chart and table assume that
all dividends and capital gain distributions were reinvested.

The Morgan Stanley Capital International EAFE(Europe, Australasia, Far East) Index (MSCIEAFEIndex) and the Lipper International
Funds Average are unmanaged benchmarks that assume reinvestment of dividends. The Lipper International Funds Average excludes the
effect of sales charges and the MSCIEAFEIndex excludes the effect of fees and sales charges. The MSCI EAFE Index measures the
performance of stocks in 20 developed markets in Europe, Australasia, and the Far East. The Lipper International Funds Average
measures the performance of mutual funds which invest in equity securities of companies whose primary trading markets are outside
the US.

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

(1) If you buy Class A shares for $1,000,000 or more, you do not pay an initial
    sales charge, but your shares will be subject to a 1% CDSC if sold within 18
    months.

(2) This amount reflects total annual fund operating expenses paid by the Fund
    for fiscal 1998, absent a one-time reimbursement to the Fund of expenses
    paid in prior years. This reimbursement had the effect of decreasing the
    Fund's actual total operating expenses to 1.69% for fiscal 1998.

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


               1 YEAR      3 YEARS    5 YEARS    10 YEARS
               ------      -------    -------    --------
Class A         $645       $1,003      $1,384     $2,450
Class B          758        1,093       1,555      2,692+
Class C          456          886       1,442      2,956
Class D          358          793       1,355      2,885

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

               1 YEAR      3 YEARS    5 YEARS    10 YEARS
               ------      -------    -------    --------
Class A         $645      $1,003      $1,384     $2,450
Class B          258         793       1,355      2,692+
Class C          356         886       1,442      2,956
Class D          258         793       1,355      2,885

SELIGMAN HENDERSON EMERGING MARKETS GROWTH FUND

INVESTMENT OBJECTIVE/PRINCIPAL STRATEGIES
The Emerging Markets Growth Fund's objective is long-term capital appreciation.

- --------------------------------------------
EMERGING MARKET:
A MARKET IN A DEVELOPING COUNTRY.
DEVELOPING COUNTRIES ARE THOSE
CLASSIFIED BY THE WORLD BANK AS
LOWER INCOME ECONOMIES, REGARDLESS
OF THEIR PARTICULAR STAGE OF DEVELOPMENT.
LOWER INCOME ECONOMIES ARE CURRENTLY
DEFINED AS THOSE WITH 1996 PER CAPITA
GROSS NATIONAL PRODUCT (GNP) OF US $9,385
OR LESS.
- --------------------------------------------

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

The Fund generally invests at least 65% of its assets in equity securities of
companies that conduct their principal business activities in emerging markets.

The Fund will focus its investments in those developing countries in which the
investment manager believes the economies are developing strongly and markets
are becoming more liquid. The Fund seeks to benefit from policies of economic
development being adopted in many developing countries. These policies include
domestic price reform, reducing internal budget deficits, privatization,
encouraging foreign investments, and developing capital markets.

The Fund uses a top-down investment style. This means the investment manager
concentrates first on regional and country allocations, then on industry
sectors, followed by fundamental analysis of individual companies.

The Fund's investments are allocated among geographic regions or countries based
on such factors as:

         o Relative economic growth potential of the various economies and
           securities markets
         o Political, financial, and social conditions influencing investment
           opportunities
         o Investor sentiment
         o Prevailing interest rates and expected levels of inflation
         o Market prices relative to historic averages

In selecting individual securities, the investment manager looks to identify
companies that it believes display one or more of the following:
         o Attractive valuations relative to earnings forecasts or other
           valuation criteria (e.g., return on equity)
         o Quality management and equity ownership by executives
         o Unique competitive advantages (e.g., market share, proprietary
           products)
         o Market liquidity
         o Potential for improvement in overall operations

The Fund generally sells a stock if the investment manager believes its target
price has been reached, its earnings are disappointing, its revenue growth has
slowed, or its underlying fundamentals have deteriorated. The Fund may also sell
a stock if the investment manager believes that negative country or regional
factors may affect a company's outlook, or to meet cash requirements.

The Fund may invest in all types of securities, many of which will be
denominated in currencies other than the US dollar. The securities may be listed
on a US or foreign stock exchange or traded in US or foreign over-the-counter
markets. The Fund normally concentrates its investments in common stocks;
however, it may invest in other types of equity securities, including securities
convertible into or exchangeable for common stock, depositary receipts, and
rights and warrants to purchase common stock. The Fund also may invest up to 25%
of its assets in preferred stock and investment grade or comparable quality debt
securities.

                                       6
<PAGE>


The Fund may invest up to 15% of its net assets in illiquid securities (i.e.,
securities that cannot be readily sold), and may from time to time enter into
forward foreign currency exchange contracts in an attempt to manage the risk of
adverse changes in currencies. The Fund may also purchase put options (which
gives the Fund the right to sell an underlying security at a particular price
during a fixed period) in an attempt to hedge against a decline in the price of
securities it holds in its portfolio. Foreign currency forward contracts and put
options on securities may not be available to the Fund on reasonable terms in
many situations and the Fund may frequently choose not to enter into such
contracts or purchase such options even when they are available.

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


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

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

PRINCIPAL RISKS


The Fund's net asset value may fluctuate more than other equity funds or other
global equity funds that do not invest heavily in emerging markets. You may
experience a decline in the value of your investment and you could lose money if
you sell your shares at a price lower than you paid for them. Emerging countries
may have relatively unstable governments, economies based on less diversified
industrial bases, and securities markets that trade a smaller number of
securities. Companies in emerging markets are often smaller, less seasoned, and
more recently organized than many US companies.

Investing in securities of foreign issuers involves risks not associated with US
investments, including settlement risks, currency fluctuation, local withholding
and other taxes, different financial reporting practices and regulatory
standards, high costs of trading, changes in political conditions,
expropriation, investment and repatriation restrictions and settlement and
custody risks. Investing in emerging markets involves a greater degree of risk,
and an investment in the Fund should be considered speculative.

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


To the extent the Fund invests some of its assets in other higher-risk
securities, such as illiquid securities, it may be subject to higher price
volatility.


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


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

PAST PERFORMANCE


The Fund offers your Classes of shares. The information below provides some
indication of the risks of investing in the Fund by showing how the performance
of Class A shares has varied year to year, as well as how the performance of
each Class (except Class C) compares to two widely-used measures of performance.
Class C is a new class of shares, effective June 1, 1999, so no performance
information is available. Although the Fund's fiscal year ends on October 31,
the performance is provided on a calendar year basis to assist you in comparing
the returns of the Fund with the returns of other mutual funds. How the Fund has
performed in the past, however, is not necessarily an indication of how the Fund
will perform in the future. Total returns will vary between each Class of shares
due to the different fees and expenses of each Class.



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

The Morgan Stanley Capital International Emerging Markets Free Index
(MSCIEMFIndex) and the Lipper Emerging Markets Funds Average are unmanaged
benchmarks that assume the reinvestment of dividends. The Lipper Emerging
Markets Funds Average excludes the effect of sales charges and the MSCIEMFIndex
excludes the effect of fees and sales charges. The MSCI EMF Index measures the
performance of stocks in 26 emerging market countries in Europe, Latin America,
and the Pacific Basin which are available to foreign investors. The Lipper
Emerging Markets Funds Average measures the performance of mutual funds which
invest at least 65% of total assets in equity securities of companies in
emerging markets.

FEES AND EXPENSES

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

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

SELIGMAN HENDERSON GLOBAL GROWTH OPPORTUNITIES FUND

INVESTMENT OBJECTIVE/PRINCIPAL STRATEGIES

The Global Growth Opportunities Fund's objective is long-term capital
appreciation.

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

The Fund invests primarily in equity securities of non-US and US growth
companies that have the potential to benefit from global economic or social
trends. The Fund may invest in companies of any size, domiciled in any country.
Typically, the Fund will invest in several countries in different geographic
regions.

The Fund uses an investment style that combines macro analysis of global trends
with in-depth research of individual companies. This means that the investment
managers analyze the rapidly changing world to identify investment themes that
they believe will have the greatest impact on global markets, and use in-depth
research to identify attractive companies around the world. The Fund focuses on
the following macro trends:

         o Economic liberalization and the flow of capital through global trade
           and investment;
         o Globalization of the world's economy.
         o The expansion of technology as an increasingly important influence
           on society;
         o Increased awareness of the importance of protecting the environment;
           and
         o The increase in life expectancy leading to changes in consumer
           demographics and a greater need for healthcare, personal security,
           and leisure.

In selecting individual securities, the investment managers look to identify
companies that they believe display one or more of the following:

         o Attractive valuations relative to earnings forecasts or other
           valuation criteria (e.g., return on equity)
         o Quality management and equity ownership by executives
         o Unique competitive advantages (e.g., market share, proprietary
           products)
         o Potential for improvement in overall operations

The Fund generally sells a stock if the investment managers believe its target
price has been reached, its earnings are disappointing, its revenue growth has
slowed, or its underlying fundamentals have deteriorated. The Fund may also sell
a stock if the investment managers believe that negative country or regional
factors or a shifting in global trends may negatively affect a company's
outlook, or to meet cash requirements.

The Fund may invest in all types of securities, many of which will be
denominated in currencies other than the US dollar. The Fund normally
concentrates its investments in common stocks; however, it may invest in other
types of equity securities, including securities convertible into or
exchangeable for common stock, depositary receipts, and rights and warrants to
purchase common stock. The Fund also may invest up to 25% of its assets in
preferred stock and investment grade or comparable quality debt securities.


The Fund may invest up to 15% of its net assets in illiquid securities (i.e.,
securities that cannot be readily sold), and may from time to time enter into
forward foreign currency exchange contracts in an attempt to manage the risk of
adverse changes in currencies. The Fund may also purchase put options (which
gives the Fund the right to sell an underlying security at a particular price
during a fixed period) in an attempt to hedge against a decline in the price of
securities it holds in its portfolio. Foreign currency forward contracts and put
options on securities may not be available to the Fund on reasonable terms in
many situations and the Fund may frequently choose not to enter into such
contracts or purchase such options even when they are available.



                                       10
<PAGE>


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

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


As with any mutual fund, the Fund may not achieve its objective.

PRINCIPAL RISKS


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

Investing in securities of foreign issuers involves risks not associated with US
investments, including settlement risks, currency fluctuation, local withholding
and other taxes, different financial reporting practices and regulatory
standards, high costs of trading, changes in political conditions,
expropriation, investment and repatriation restrictions and settlement and
custody risks.


The Fund seeks to limit the risk of investing in foreign securities by
diversifying its investments among different countries, as well as among
different themes. Diversification reduces the effect events in any one country
will have on the Fund's entire investment portfolio. However, a decline in the
value of the Fund's investments in one country may offset potential gains from
investments in another country.

If global trends do not develop as the manager expects, the Fund's performance
could be negatively affected.


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


To the extent the Fund invests some of its assets in higher-risk securities,
such as illiquid securities, it may be subject to higher price volatility.


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


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

PAST PERFORMANCE


The Fund offers four Classes of shares. The information below provides some
indication of the risks of investing in the Fund by showing how the performance
of Class A shares has varied year to year, as well as how the performance of
each Class (except Class C) compares to two widely-used measures of performance.
Class C is a new class of shares, effective June 1, 1999, so no performance
information is available. Although the Fund's fiscal year ends on October 31,
the performance is provided on a calendar year basis to assist you in comparing
the returns of the Fund with the returns of other mutual funds. How the Fund has
performed in the past, however, is not necessarily an indication of how the Fund
will perform in the future. Total returns will vary between each Class of shares
due to the different fees and expenses of each Class.


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

FEES AND EXPENSES

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

invest $10,000 in the Fund for each period and then sell all of your shares at
the end of that period, (2) your investment has a 5% return each year, and (3)
the Fund's operating expenses remain the same. Although your actual expenses may
be higher or lower, based on these assumptions your expenses would be:

SELIGMAN HENDERSON GLOBAL SMALLER COMPANIES FUND

INVESTMENT OBJECTIVE/PRINCIPAL STRATEGIES
The Global Smaller Companies Fund's objective is long-term capital appreciation.

- ----------------------------
SMALLER COMPANIES:
COMPANIES WITH MARKET
CAPITALIZATION (AT THE TIME
OF PURCHASE BY THE FUND)
EQUIVALENT TO US $1 BILLION
OR LESS.
- ----------------------------

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

The Fund generally invests at least 65% of its assets in equity securities of
smaller US and non-US companies. The Fund may invest in companies domiciled in
any country, although it typically invests in developed countries. The Fund will
generally invest in several countries in different geographic regions.

The Fund uses an investment style that combines top-down macro-economic analysis
with bottom-up fundamental research into individual company attractiveness. This
means that the investment managers identify countries that they believe offer
good investment opportunities, and use extensive in-depth research to identify
attractive smaller companies around the world. The investment managers look at
one or more of the following factors when making country allocation decisions

         o Relative economic growth potential of the various economies and
           securities markets
         o Political, financial, and social conditions influencing investment
           opportunities
         o Investor sentiment
         o Prevailing interest rates and expected levels of inflation
         o Market prices relative to historic averages

In selecting individual securities, the investment managers look for companies
that they believe display one or more of the following:

         o Attractive valuations relative to earnings forecasts or other
           valuation criteria (e.g., return on equity)
         o Quality management and  equity ownership by executives
         o Unique competitive advantages (e.g.,   market share, proprietary
           products)
         o Market liquidity
         o Potential for improvement in overall operations

The Fund generally sells a stock if the investment managers believe its target
price has been reached, its earnings are disappointing, its revenue growth has
slowed, or its underlying fundamentals have deteriorated. The Fund may also sell
a stock if the investment managers believe that negative country or regional
factors may affect a company's outlook, or to meet cash requirements. The Fund
anticipates that it will continue to hold securities of companies that grow or
expand so long as the investment managers believe the securities continue to
offer prospects of long-term growth.

The Fund may invest in all types of securities, many of which will be
denominated in currencies other than the US dollar. The Fund normally
concentrates its investments in common stocks; however, it may invest in other
types of equity securities, including securities convertible into or
exchangeable for common stock, depositary receipts, and rights and warrants to
purchase common stock. The Fund also may invest up to 25% of its assets in
preferred stock and investment grade or comparable quality debt securities.


The Fund may invest up to 15% of its net assets in illiquid securities (i.e.,
securities that cannot be readily sold), and may from time to time enter into
forward foreign currency exchange contracts in an attempt to manage the risk of
adverse changes in currencies. The Fund may also purchase put options (which
gives the Fund the right to sell an underlying security at a particular price
during a fixed period) in an attempt to hedge against a decline in the price of
securities it holds in its portfolio. Foreign currency forward contracts and put
options on securities may not be available to the Fund on reasonable terms in
many situations and the Fund may frequently choose not to enter into such
contracts or purchase such options even when they are available.



                                       14
<PAGE>



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

The Fund may change its principal strategies if the Board of Directors believes
doing so is consistent with the Fund's objective. The Board of Directors may
change the definition of "smaller companies" if they conclude that such a change
is appropriate. The Fund's objective may be changed only with the approval of
shareholders.


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


PRINCIPAL RISKS


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

Investing in securities of foreign issuers involves risks not associated with US
investments, including settlement risks, currency fluctuation, local withholding
and other taxes, different financial reporting practices and regulatory
standards, high costs of trading, changes in political conditions,
expropriation, investment and repatriation restrictions and settlement and
custody risks.


Investments in smaller companies typically involve greater risks than
investments in larger companies. Small company stocks, as a whole, may
experience larger price fluctuations than large-company stocks or other types of
investments. Some small companies may have shorter operating histories, less
experienced management and limited product lines, markets, and financial or
managerial resources.


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


To the extent the Fund invests some of its assets in higher-risk securities,
such as illiquid securities, it may be subject to higher price volatility.


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


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

PAST PERFORMANCE


The Fund offers four Classes of shares. The information below provides some
indication of the risks of investing in the Fund by showing how the performance
of Class A shares has varied year to year, as well as how the performance of
each Class (except Class C) compares to two widely-used measures of performance.
Class C is a new class of shares, effective June 1, 1999, so no performance
information is available. Although the Fund's fiscal year ends on October 31,
the performance is provided on a calendar year basis to assist you in comparing
the returns of the Fund with the returns of other mutual funds. How the Fund has
performed in the past, however, is not necessarily an indication of how the Fund
will perform in the future. Total returns will vary between each Class of shares
due to the different fees and expenses of each Class.


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

SELIGMAN HENDERSON GLOBAL TECHNOLOGY FUND

INVESTMENT OBJECTIVE/PRINCIPAL STRATEGIES
The Global Technology Fund's objective is long-term capital appreciation.

- -------------------------------------
TECHNOLOGY:
THE USE OF SCIENCE TO CREATE NEW
PRODUCTS AND SERVICES. THE INDUSTRY
COMPRISES INFORMATION TECHNOLOGY AND
COMMUNICATIONS, AS WELL AS MEDICAL-,
ENVIRONMENTAL- AND BIO-TECHNOLOGY.
- -------------------------------------

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

The Fund generally invests at least 65% of its assets in equity securities of US
and non-US companies with business operations in technology and
technology-related industries. Technology-related companies are those companies
that use technology extensively to improve their business processes and
applications. The Fund may invest in companies domiciled in any country which
the investment managers believe to be appropriate to the Fund's objective. The
Fund generally invests in several countries in different geographic regions.

The Fund may invest in companies of any size. Securities of large companies that
are well established in the world technology market can be expected to grow with
the market and will frequently be held by the Fund. However, rapidly changing
technologies and expansion of technology and technology-related industries often
provide a favorable environment for companies of small-to-medium size, and the
Fund may invest in these companies as well.

The investment managers seek to identify those technology companies that they
believe have the greatest prospects for future growth, regardless of their
country of origin. The Fund uses an investment style that combines research into
individual company attractiveness with macro analysis. This means that the
investment managers use extensive in-depth research to identify attractive
technology companies around the world, while seeking to identify particularly
strong technology sectors and/or factors within regions or specific countries
that may affect investment opportunities. In selecting individual securities,
the investment managers look for companies that they believe display one or more
of the following:

         o Above-average growth prospects
         o High profit margins
         o Attractive valuations relative to earnings forecasts or other
           valuation criteria (e.g., return on equity)
         o Quality management and equity ownership by executives
         o Unique competitive advantages (e.g., market share, proprietary
           products)
         o Potential for improvement in overall operations

The Fund generally sells a stock if the investment managers believe its target
price has been reached, its earnings are disappointing, its revenue growth has
slowed, or its underlying fundamentals have deteriorated. The Fund may also sell
a stock if the investment managers believe that negative country or regional
factors may affect a company's outlook, or to meet cash requirements.

The Fund may invest in all types of securities, many of which will be
denominated in currencies other than the US dollar. The Fund normally
concentrates its investments in common stocks; however, it may invest in other
types of equity securities, including securities convertible into or
exchangeable for common stock, depositary receipts, and rights and warrants to
purchase common stock. The Fund also may invest up to 25% of its assets in
preferred stock and investment grade or comparable quality debt securities. The
Fund may also invest in depositary receipts, which are publicly traded
instruments generally issued by US or foreign banks or trust companies that
represent securities of foreign issuers.


                                       18
<PAGE>


The Fund may invest up to 15% of its net assets in illiquid securities (i.e.,
securities that cannot be readily sold), and may from time to time enter into
forward foreign currency exchange contracts in an attempt to manage the risk of
adverse changes in currencies. The Fund may also purchase put options (which
gives the Fund the right to sell an underlying security at a particular price
during a fixed period) in an attempt to hedge against a decline in the price of
securities it holds in its portfolio. Foreign currency forward contracts and put
options on securities may not be available to the Fund on reasonable terms in
many situations and the Fund may frequently choose not to enter into such
contracts or purchase such options even when they are available.


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


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


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


PRINCIPAL RISKS


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

Investing in securities of foreign issuers involves risks not associated with US
investments, including settlement risks, currency fluctuation, local withholding
and other taxes, different financial reporting practices and regulatory
standards, high costs of trading, changes in political conditions,
expropriation, investment and repatriation restrictions and settlement and
custody risks.


The Fund may be susceptible to factors affecting technology and
technology-related industries and the Fund's net asset value may fluctuate more
than a fund that invests in a wider range of industries. Technology companies
are often smaller and less experienced companies and may be subject to greater
risks than larger companies, such as limited product lines, markets, and
financial or managerial resources. These risks may be heightened for technology
companies in foreign markets.

The Fund seeks to limit risk by diversifying its investments among different
sectors within the technology industry, as well as among different countries.
Diversification reduces the effect the performance of any one sector or events
in any one country will have on the Fund's entire investment portfolio. However,
a decline in the value of one of the Fund's investments may offset potential
gains from other investments.


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


To the extent the Fund invests some of its assets in higher-risk securities,
such as illiquid securities, it may be subject to higher price volatility.


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


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

SELIGMAN HENDERSON GLOBAL TECHNOLOGY FUND

PAST PERFORMANCE


The Fund offers four Classes of shares. The information below provides some
indication of the risks of investing in the Fund by showing how the performance
of Class A shares has varied year to year, as well as how the performance of
each Class (except Class C) compares to four widely-used measures of
performance. Class C is a new class of shares, effective June 1, 1999, so no
performance information is available. Although the Fund's fiscal year ends on
October 31, the performance is provided on a calendar year basis to assist you
in comparing the returns of the Fund with the returns of other mutual funds. How
the Fund has performed in the past, however, is not necessarily an indication of
how the Fund will perform in the future. Total returns will vary between each
Class of shares due to the different fees and expenses of each Class.


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

FEES AND EXPENSES

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

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


                1 YEAR      3 YEARS    5 YEARS    10 YEARS
                ------      -------    -------    --------
Class A          $637        $ 976      $1,339     $2,357
Class B           746        1,058       1,496      2,578+
Class C           444          850       1,383      2,839
Class D           346          758       1,296      2,766


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


               1 YEAR      3 YEARS    5 YEARS    10 YEARS
                -----      -------    -------    --------
Class A         $637        $976      $1,339     $2,357

YEAR 2000

As the millennium approaches, mutual funds, financial and business
organizations, and individuals could be adversely affected if their computer
systems do not properly process and calculate date-related information and data
on and after January 1, 2000. Like other mutual funds, the Funds rely upon
service providers and their computer systems for their day-to-day operations.
Many of the Funds' service providers in turn depend upon computer systems of
their vendors. Seligman and SDC have established a year 2000 project team. The
team's purpose is to assess the state of readiness of Seligman and SDC and the
Funds' other service providers and vendors. The team is comprised of several
information technology and business professionals as well as outside
consultants. The Project Manager of the team reports directly to the
Administrative Committee of Seligman. The Project Manager and other members of
the team also report to the Funds' Board of Directors and its Audit Committee.

The team has identified the service providers and vendors who furnish critical
services or software systems to the Funds, including securities firms that
execute portfolio transactions for the Funds and firms responsible for
shareholder account recordkeeping. The team is working with these critical
service providers and vendors to evaluate the impact year 2000 issues may have
on their ability to provide uninterrupted services to the Funds. The team will
assess the feasibility of their year 2000 plans. The team has made progress on
its year 2000 contingency plans - recovery efforts the team will employ in the
event that year 2000 issues adversely affect the Funds. The team anticipates
finalizing these plans in the near future.

The Funds anticipate the team will implement all significant components of the
team's year 2000 plans by mid-1999, including appropriate testing of critical
systems and receipt of satisfactory assurances from critical service providers
and vendors regarding their year 2000 compliance. The Funds believe that the
critical systems on which they rely will function properly on and after the year
2000, but this is not guaranteed. If these systems do not function properly, or
the Funds' critical service providers are not successful in implementing their
year 2000 plans, the Funds' operations may be adversely affected, including
pricing and securities trading and settlement, and the provision of shareholder
services.


In addition, the Funds may hold securities of issuers whose underlying business
leaves them susceptible to year 2000 issues. The Funds may also hold securities
issued by governmental or quasi-governmental issuers, which, like other
organizations, are also susceptible to year 2000 concerns. Year 2000 issues may
affect an issuer's operations, creditworthiness, and ability to make timely
payment on any indebtedness and could have an adverse impact on the value of its
securities. If the Funds hold these securities, the Funds' performance could be
negatively affected. Seligman seeks to identify an issuer's state of year 2000
readiness as part of the research it employs. However, the perception of an
issuer's year 2000 preparedness is only one of the many factors considered in
determining whether to buy, sell, or continue to hold a security. Information
provided by issuers concerning their state of readiness may or may not be
accurate or readily available. Further, the Fund may be adversely affected if
the domestic or foreign exchanges, markets, depositories, clearing agencies, or
governments or third parties responsible for infrastructure needs do not address
their year 2000 issues in a satisfactory manner.


SDC has informed the Funds that it does not expect the cost of its services to
increase materially as a result of the modifications to its computer systems
necessary to prepare for the year 2000. The Funds will not pay to remediate the
systems of Seligman or bear directly the costs to remediate the systems of any
other service providers or vendors, other than SDC.

EURO CONVERSION

On January 1, 1999, 11 of the 15 member countries in the European Union adopted
the "euro" as a common legal currency. For European issuers, and other entities
with significant markets or operations in Europe (whether or not in the
participating countries), the euro conversion may create strategic challenges as
these entities adapt to a single transnational currency.

The Funds, Seligman, and HIML are monitoring the changing marketplace in Europe
to seek to identify investment opportunities created by the euro and avoid
investments that may adversely affect the performance of any Fund. Despite these
efforts, a Fund's performance may be adversely affected if the issuers of
securities that are purchased, held, or sold by a Fund do not adapt to the
potential changes in the European marketplace as a result of the euro. For
example, the euro will likely result in greater price transparency (making it
more difficult for businesses to charge different prices for the same products
on a country-by-country basis), thereby creating a more competitive marketplace
in Europe. As a result, European issuers and other issuers with significant
markets or operations in Europe (whether or not in the participating countries),
may be adversely affected if they do not adapt to this new competitive
marketplace by cutting costs and streamlining operations. Further, any
participating country may opt out of the euro within the first three years. A
participating country may decide to opt out of the euro for several reasons,
including high unemployment, lack of economic growth, or frustration with the
lack of unity in the participating countries' economies. The risk of one or more
participating countries opting out of the euro is enhanced by the participating
countries' lack of control over their own monetary policies as they have
delegated this function to the European Central Bank. Issuers in a participating
country, as well as other issuers globally, may be adversely impacted in the
event that a participating country terminates its participation in the euro or
the euro itself collapses due to disagreements among the governments of the
participating countries.

SHAREHOLDER INFORMATION

DECIDING WHICH CLASS OF SHARES TO BUY


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


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

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

   o A 1% CDSC on shares sold within eighteen months of purchase.
   o Annual 12b-1 fee (for distribution and shareholder services) of 1.00%.
   o No automatic conversion to Class A shares, so you will be subject to higher

   o No CDSC when you sell shares purchased with reinvested dividends or capital
     gain distributions.

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

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


CLASS D*


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

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

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

Each Fund has adopted a plan under Rule 12b-1 of the Investment Company Act of
1940 that allows each Class to pay 12b-1 fees for the sale and distribution of
its shares and/or for providing services to shareholders.

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


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



HOW CDSCS ARE CALCULATED


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


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


                                       27
<PAGE>

PRICING OF FUND SHARES


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


- --------------------------------------
NAV:
COMPUTED SEPARATELY FOR EACH
CLASS BY DIVIDING THAT CLASS'S
SHARE OF THE NET ASSETS OF THE
FUND (I.E., ITS ASSETS LESS
LIABILITIES) BY THE TOTAL NUMBER
OF OUTSTANDING SHARES OF THE CLASS.
- -------------------------------------

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

The NAV of each Fund's shares is determined each day, Monday through Friday, on
days that the NYSE is open for trading. Because the Funds have portfolio
securities that are primarily listed on foreign exchanges that may trade on
weekends or other days when the Funds do not price their shares, the value of a
Fund's portfolio securities may change on days when you may not be able to buy
or sell Fund shares. Because of their higher 12b-1 fees, the NAV of Class B and
Class D shares will generally be lower than the NAV of Class A shares of the
same Fund.

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

OPENING YOUR ACCOUNT


The Funds' shares are sold through authorized broker/dealers or financial
advisors who have sales agreements with Seligman Advisors. There are several
programs under which you may be eligible for reduced sales charges or lower
minimum investments. Ask your financial advisor if any of these programs apply
to you. Class D shares are not available to all investors. For more information,
see "Deciding Which Class of Share to Buy - Class D."


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

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

The required minimum initial investments are:

     o Regular (non-retirement) accounts: $1,000
     o For accounts opened concurrently with Invest-A-Check(R):
       $100 to open if you will be making monthly investments
       $250 to open if you will be making quarterly investments

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


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


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

HOW TO BUY ADDITIONAL SHARES


After you have made your initial investment, there are many options available to
make additional purchases of Fund shares. Subsequent investments must be for
$100 or more. Shares may be purchased through your authorized financial advisor,
or you may send a check directly to SDC. Please provide either an investment
slip or a note that provides your name(s), Fund name, and account number. Unless
you indicate otherwise, your investment will be made in the Class you already
own. Send investment checks to:

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


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

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

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


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


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

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

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

SELIGMAN TIME HORIZON MATRIX(SM). (Requires an initial total investment of
$10,000.) This is a needs-based investment process, designed to help you and
your financial advisor plan to seek your long-term financial goals. It considers
your financial needs, and helps frame a personalized asset allocation strategy
around the cost of your future commitments and the time you have to meet them.
Contact your financial advisor for more information.

SELIGMAN HARVESTER. If you are a retiree or nearing retirement, this program is
designed to help you establish an investment strategy that seeks to meet your
needs throughout your retirement. The strategy is customized to your personal
financial situation by allocating your assets to seek to address your income
requirements, prioritizing your expenses, and establishing a prudent withdrawal
schedule. Contact your financial advisor for more information.

<PAGE>

HOW TO EXCHANGE SHARES AMONG THE SELIGMAN MUTUAL FUNDS


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


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


If you exchange into a new fund, you must exchange enough to meet the new fund's
minimum initial investment. See "The Seligman Mutual Funds" for a list of the
funds available for exchange. Before making an exchange, contact your financial
advisor or SDC to obtain the applicable fund prospectus(es). You should read and
understand a fund's prospectus before investing. Some funds may not offer all
Classes of shares.


HOW TO SELL SHARES

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


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


You may sell shares to the Fund through a broker/dealer or your financial
advisor. The Fund does not charge any fees or expenses, other than any
applicable CDSC, for this transaction; however the dealer or financial advisor
may charge a service fee. Contact your financial advisor for more information.

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



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


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

- -------------------------------------------------------------------
SIGNATURE GUARANTEE:
PROTECTS YOU AND THE FUNDS FROM FRAUD. IT GUARANTEES THAT
A SIGNATURE IS GENUINE. A GUARANTEE MUST BE
OBTAINED FROM AN ELIGIBLE FINANCIAL INSTITUTION. NOTARIZATION BY A
NOTARY PUBLIC IS not AN ACCEPTABLE GUARANTEE.
- -------------------------------------------------------------------

You may need to provide additional documents to sell Fund shares if you are:

   o a corporation;
   o an executor or administrator;
   o a trustee or custodian; or
   o in a retirement plan.

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

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

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


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

   o  Sell uncertificated shares (up to $50,000 per day, payable to account
      owner(s) and mailed to address of record).

   o  Exchange shares between funds.

   o  Change dividend and/or capital gain distribution options.

   o  Change your address.

   o  Establish systematic withdrawals to address of record.

If you do not complete an account application when you open your account,
telephone services must be elected on a supplemental election form (which may
require a signature guarantee).

Restrictions apply to certain types of accounts:

   o  Trust accounts on which the current trustee is not listed may not sell
      Fund shares by phone.

   o  Corporations may not sell Fund shares by phone.

   o  IRAs may only exchange Fund shares or request address changes by phone.

   o  Group retirement plans may not sell Fund shares by phone; plans that allow
      participants to exchange by phone must provide a letter of authorization
      signed by the plan custodian or trustee and provide a supplemental
      election form signed by all plan participants.

Unless you have current ACH bank information on file, you will not be able to
sell Fund shares by phone within thirty days following an address change.

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

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

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

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


REINSTATEMENT PRIVILEGE

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

DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS

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

- --------------------------------
DIVIDEND:
A PAYMENT BY A MUTUAL
FUND, USUALLY DERIVED
FROM THE FUND'S NET INVESTMENT
INCOME (DIVIDENDS AND
INTEREST EARNED ON PORTFOLIO
SECURITIES LESS EXPENSES).

CAPITAL GAIN DISTRIBUTION:
A PAYMENT TO MUTUAL FUND
SHAREHOLDERS WHICH
REPRESENTS PROFITS REALIZED
ON THE SALE OF SECURITIES IN
A FUND'S PORTFOLIO.

EX-DIVIDEND DATE:
THE DAY ON WHICH ANY
DECLARED DISTRIBUTIONS
(DIVIDENDS OR CAPITAL GAINS)
ARE DEDUCTED FROM A FUND'S
ASSETS BEFORE IT CALCULATES
ITS NAV.
- --------------------------------


You may elect to:

(1) reinvest both dividends and capital gain distributions;

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

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

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

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

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

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


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


TAXES

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


Dividends paid by the Fund are taxable to you as ordinary income. You may be
taxed at different rates on capital gains distributed by the Fund depending on
the length of time the Fund holds its assets.


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

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

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

FINANCIAL HIGHLIGHTS


The tables below are intended to help you understand the financial performance
of each Fund's Classes for the past five years or, if less than five years, the
period of the Class's operations. Class C is a new Class, effective June 1,
1999, so financial highlights are not available. Certain information reflects
financial results for a single share of a Class that was held throughout the
periods shown. "Total return" shows the rate that you would have earned (or
lost) on an investment in the Fund, assuming you reinvested all your dividends
and capital gain distributions. Total returns do not reflect any sales charges.
Deloitte & Touche LLP, independent auditors, have audited this information.
Their report, along with each Fund's financial statements, is included in the
Funds' annual report, which is available upon request.

                                  Fund History

Seligman Henderson Global Fund Series, Inc. was incorporated in Maryland on
November 22, 1991 under the name Seligman International Fund Series, Inc. It
changed its name to its present name on May 25, 1993.


            Description of the Funds and Their Investments and Risks

Classification

Seligman Henderson Global Fund Series, Inc. is a diversified, open-end
management investment company, or mutual fund. It consists of five separate and
distinct series, or funds:

Seligman Henderson International Fund (International Fund) Seligman Henderson
Emerging Markets Growth Fund (Emerging Markets Growth Fund) Seligman Henderson
Global Growth Opportunities Fund (Global Growth Opportunities Fund) Seligman
Henderson Global Smaller Companies Fund (Global Smaller Companies Fund) Seligman
Henderson Global Technology Fund (Global Technology Fund)

Investment Strategies and Risks

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

General. In allocating each Fund's investments among geographic regions and
individual countries, the investment manager will consider such factors as the
relative economic growth potential of the various economies and securities
markets; expected levels of inflation; financial, social and political
conditions influencing investment opportunities; and the outlook for currency
relationships.

Each Fund may invest in all types of securities, many of which will be
denominated in currencies other than the US dollar. Each Fund will normally
invest its assets in equity securities, including common stock, securities
convertible into or exchangeable for common stock, depositary receipts, and
warrants. A Fund may, however, invest up to 25% of its assets in preferred stock
and debt securities. A Fund that invests "primarily" in a certain type of
security invests at least 65% of its total assets in that type of security.
Dividends or interest income are considered only when the investment manager
believes that such income will favorably influence the market value of a
security in light of each Fund's objective of capital appreciation. Equity
securities in which each Fund invests may be listed on a US or foreign stock
exchange or traded in US or foreign over-the-counter markets.

Debt securities in which each Fund may invest are not required to be rated by a
recognized rating agency. As a matter of policy, each Fund, with the exception
of the Emerging Markets Growth Fund, will invest only in "investment grade" debt
securities or, in the case of unrated securities, debt securities that are, in
the opinion of the investment manager, of equivalent quality to "investment
grade" securities. "Investment grade" debt securities are rated within the four
highest rating categories as determined by Moody's Investors Service, Inc.
(Moody's) or Standard & Poor's Rating Service (S&P). Securities rated within the
highest of the four investment grade categories (i.e., Aaa by Moody's and AAA by
S&P) are judged to be of the best quality and carry the smallest degree of risk.
For capital appreciation, the Emerging Markets Growth Fund may invest up to 5%
of its assets in governmental and corporate debt securities that, at the time of
purchase by the Fund, are rated Baa or lower by Moody's and BBB or lower by S&P
or, if unrated, deemed by the investment manager to be of comparable quality.
The Emerging Markets Growth Fund will not invest in debt securities rated lower
than C by Moody's or C by S&P or, if unrated, deemed by the investment manager
to be of comparable quality. Securities rated Baa/BBB or lower lack high quality
investment characteristics and may also have speculative characteristics.
(Appendix A to the Statement of Additional Information contains a description of
these rating categories.) Debt securities are interest-rate sensitive, so their
value tends to decrease when interest rates rise and increase when interest
rates fall.

                                       2

<PAGE>

Each Fund may invest in securities represented by European Depositary Receipts
(EDRs), American Depositary Receipts (ADRs) and Global Depositary Receipts
(GDRs) (collectively, Depositary Receipts). ADRs are receipts generally issued
by a domestic bank or trust company that represent the deposit 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 US dollars at a price that
generally reflects the US dollar equivalent of the home country share price.
EDRs and GDRs are receipts similar to ADRs and are typically issued by foreign
banks or trust companies and traded in Europe. Depositary Receipts may be issued
as sponsored or unsponsored programs. In sponsored programs, the issuer has made
arrangements to have its securities traded in the form of a Depositary Receipt.
In unsponsored programs, the issuer may not be directly involved in the creation
of the program. Although regulatory requirements with respect to sponsored and
unsponsored programs are generally similar, the issuers of unsponsored
Depositary Receipts are not obligated to disclose material information in the
United States and, therefore, the import of such information may not be
reflected in the market value of such securities. For purposes of a Fund's
investment policies, an investment in Depositary Receipts will be deemed to be
an investment in the underlying security.

By investing in foreign securities, a Fund will attempt to take advantage of
differences among economic trends and the performance of securities markets in
various countries. To date, the market values of securities of issuers located
in different countries have moved relatively independently of each other,
although markets in certain regions tend to move in the same direction. During
certain periods, the return on equity investments in some countries has exceeded
the return on similar investments in the United States. The investment manager
believes that, in comparison with investment companies investing solely in
domestic securities, it may be possible to obtain significant appreciation from
a portfolio of foreign investments and securities from various markets that
offer different investment opportunities and are affected by different economic
trends. International and global diversification reduces the effect events in
any one country will have on a Fund's entire investment portfolio. Of course, a
decline in the value of a Fund's investments in one country may offset potential
gains from investments in another country.

Foreign Investment Risk Factors. Investments in securities of foreign issuers
may involve risks that are not associated with domestic investments, and there
can be no assurance that a Fund's foreign investments will present less risk
than a portfolio of domestic securities. Foreign issuers may lack uniform
accounting, auditing and financial reporting standards, practices and
requirements, and there is generally less publicly available information about
foreign issuers than there is about US issuers. Governmental regulation and
supervision of foreign stock exchanges, brokers and listed companies may be less
pervasive than is customary in the United States. Securities of some foreign
issuers are less liquid, and their prices are more volatile, than securities of
comparable domestic issuers. Foreign securities settlement practices may in some
instances be subject to delays and related administrative uncertainties which
could result in temporary periods when assets of a Fund are uninvested and no
return is earned thereon and may involve a risk of loss to a Fund. Foreign
securities markets may have substantially less trading volume than US markets
and far fewer traded issues. Fixed brokerage commissions on foreign securities
exchanges are generally higher than in the United States and transaction costs
with respect to smaller capitalization companies may be higher than those of
larger capitalization companies. Income from foreign securities may be reduced
by a withholding tax at the source or other foreign taxes. In some countries,
there may also be the possibility of expropriation or confiscatory taxation (in
which case a Fund could lose its entire investment in a certain market);
limitations on the removal of moneys or other assets of a Fund; political or
social instability or revolution; or diplomatic developments that could affect
investments in those countries. In addition, it may be difficult to obtain and
enforce a judgment in a court outside the United States.

Each Fund may invest in sovereign debt. The actions of governments concerning
their respective economies could have an important effect on their ability or
willingness to service their sovereign debt. Such actions could have significant
effects on market conditions and on the prices of securities and instruments
held by a Fund, including the securities and instruments of foreign private
issuers. Factors which may influence the ability or willingness of foreign
sovereigns to service debt include, but are not limited to: the availability of
sufficient foreign exchange on the date payment is due; the relative size of its
debt service burden to the economy as a whole; its balance of payments
(including export performance) and cash flow situation; its access to
international credits and investments; fluctuations in interest and

                                       3

<PAGE>

currency rates and reserves; and its government's policies towards the
International Monetary Fund, the World Bank and other international agencies. If
a foreign sovereign defaults on all or a portion of its foreign debt, a Fund may
have limited legal recourse against the issuer and/or guarantor. In some cases,
remedies must be pursued in the courts of the defaulting party itself, and the
ability of the holder of foreign sovereign debt securities to obtain recourse
may be subject to the political climate in the prevailing country.

Foreign Currency Risk Factors. Investments in foreign securities will usually be
denominated in foreign currency, and each Fund may be affected, favorably or
unfavorably, by the relative strength of the US dollar, changes in foreign
currency and US dollar exchange rates, and exchange control regulations. A Fund
may incur costs in connection with conversions between various currencies. A
Fund's net asset value per share will be affected by changes in currency
exchange rates. Changes in foreign currency exchange rates may also affect the
value of dividends and interest earned, gains and losses realized on the sale of
securities, and net investment income and gains, if any, to be distributed to
shareholders by a Fund. The rate of exchange between the US dollar and other
currencies is generally determined by the forces of supply and demand in the
foreign exchange markets (which in turn are affected by interest rates, trade
flow, and numerous other factors, including, in some countries, local
governmental intervention), but can sometimes be affected by the imposition of
fixed exchange rates that may overvalue a foreign currency, to the detriment of
foreign investors.

Emerging Market Investment Risk Factors. Some of the risks described in the
preceding paragraphs may be more severe for investments in emerging countries.
By comparison with the United States and other developed countries, emerging
countries may have relatively unstable governments, economies based on a less
diversified industrial base and securities markets that trade a smaller number
of securities. Companies in emerging markets may generally be smaller, less
seasoned and more recently organized than many domestic companies. Prices of
securities traded in the securities markets of emerging countries tend to be
volatile. Furthermore, foreign investors are subject to many restrictions in
emerging countries. These restrictions may require, among other things,
governmental approval prior to making investments or repatriating income or
capital or the payment of special levies and taxes, or may impose limits on the
amount or type of securities held by foreigners or on the companies in which the
foreigners may invest.

The economies of individual emerging countries may differ favorably or
unfavorably from the US economy in such respects as growth of gross domestic
product, rates of inflation, currency depreciation, capital reinvestment,
resource self-sufficiency, and balance of payment position and may be based on a
substantially less diversified industrial base. Further, the economies of
emerging countries generally are heavily dependent upon international trade and,
accordingly, have been, and may continue to be, adversely affected by trade
barriers, exchange controls, managed adjustments in relative currency values,
and other protectionist measures imposed or negotiated by the countries with
which they trade. These economies also have been, and may continue to be,
adversely affected by economic conditions in the countries with which they
trade. Smaller Company Investment Risk Factors. The investment manager believes
that smaller companies generally have greater earnings and sales growth
potential than larger companies. However, investments in such companies may
involve greater risks, such as limited product lines, limited markets and
limited financial or managerial resources. Less frequently traded securities may
be subject to more abrupt price movements than securities of larger companies.

Technology Investment Risk Factors. The value of Global Technology Fund shares
may be susceptible to factors affecting technology and technology-related
industries and to greater risk and market fluctuation than an investment in a
fund that invests in a broader range of portfolio securities. Technology and
technology-related industries may be subject to greater governmental regulation
than many other industries in certain countries, as well as changes in
governmental policies, and the need for regulatory approvals may have a material
adverse effect on these industries. Additionally, these companies may be subject
to risks of developing technologies, competitive pressures, and other factors
and are dependent upon consumer and business acceptance as new technologies
evolve. Securities of smaller, less experienced companies also may involve
greater risks, such as limited product lines, limited markets and limited

                                       4

<PAGE>

financial or managerial resources, and trading in such securities may be subject
to more abrupt price movements than trading in the securities of larger
companies.

Derivatives. Each Fund may invest in financial instruments commonly known as
"derivatives" only for hedging or investment purposes. A Fund will not invest in
derivatives for speculative purposes, which means where the derivative
investment exposes the Fund to undue risk of loss, such as where the risk of
loss is greater than the cost of the investment.

A derivative is generally defined as an instrument whose value is derived from,
or based upon, some underlying index, reference rate (e.g., interest rates or
currency exchange rates), security, commodity, or other asset. A Fund will not
invest in a specific type of derivative without prior approval from the Funds'
Board of Directors after consideration of, among other things, how the
derivative instrument serves the Fund's investment objective, and the risks
associated with the investment. The only types of derivatives in which each Fund
is currently permitted to invest are forward foreign currency exchange
contracts, stock purchase rights and warrants, and put options.

Forward Foreign Currency Exchange Contracts. The investment manager will
consider changes in exchange rates in making investment decisions. As one way of
managing exchange rate risk, each Fund may enter into forward currency exchange
contracts. 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. A Fund will usually enter into these
contracts to fix the US dollar value of a security that 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. A Fund may also use these contracts to hedge
the US dollar value of securities it already owns. A Fund may be required to
cover certain forward currency contract positions by establishing a segregated
account with its custodian that will contain only liquid assets, such as US
Government securities or other liquid high-grade debt obligations.

A 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 another
currency (including the US dollar). In this case the contract would approximate
the value of some or all of a Fund's portfolio securities denominated in such
foreign currency. If appropriate, a Fund may hedge all or part of its foreign
currency exposure through the use of a basket of currencies or a proxy currency
where such currencies or proxy currency act as an effective proxy for other
currencies. In these circumstances, a Fund may enter into a forward contract
where the amount of the foreign currency to be sold exceeds the value of the
securities denominated in such currency. The use of this basket hedging
technique may be more efficient and economical than entering into separate
forward contracts for each currency held in a Fund. The precise matching of the
forward contract amounts and the value of the securities involved will not
generally be possible since the future value of such securities in foreign
currencies will change as a consequence of market movement 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, a Fund may commit a substantial
portion or the entire value of its assets to the consummation of these
contracts. The investment manager will consider the effect a substantial
commitment of its assets to forward contracts would have on the investment
program of each Fund and its ability to purchase additional securities.

Except as set forth above and immediately below, a 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 a Fund to deliver an amount of
foreign currency in excess of the value of such Fund's portfolio securities or
other assets denominated in that currency. A 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 its 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, having
a value at least equal at all times to the amount of such excess. Under normal
circumstances, consideration of the prospect for currency parities will be
incorporated into the longer-term investment decisions made with regard to
overall diversification strategies. However, the investment manager believes
that it is important to have the flexibility to enter into such forward
contracts when it determines that the best interests of a Fund will be served.

                                       5

<PAGE>

At the maturity of a forward contract, a 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 a 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 foreign currency such
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 a
Fund is obligated to deliver. However, a 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 a Fund retains the portfolio security and engages in an offsetting
transaction, such Fund will incur a gain or a loss (as described below) to the
extent that there has been movement in forward contract prices. If a 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 a 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, such 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, a 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 generally
be limited to the transactions described above. However, each Fund reserves the
right to enter into forward foreign currency contracts for different purposes
and under different circumstances. Of course, a 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 investment
manager.

Although a Fund will seek to benefit by using forward contracts, anticipated
currency movements may not be accurately predicted and the Fund may therefore
incur a gain or loss on a forward contract. A forward contract may help reduce a
Fund's losses on securities denominated in foreign currency, but it may also
reduce the potential gain on the securities depending on changes in the
currency's value relative to the US dollar or other currencies. Additionally,
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. Foreign currency forward
contracts may not be available to a Fund on reasonable terms in many situations
and a Fund may frequently choose not to enter into such contracts even when they
are available.

Investors 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 or
"spread" based on the difference between the prices at which they are buying and
selling various currencies. Thus, a dealer may offer to sell a foreign currency
to a Fund at one rate, while offering a lesser rate of exchange should the Fund
desire to resell that currency to the dealer.

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

A 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 of a Fund may be invested in warrants not listed on the New York or
American

                                       6

<PAGE>

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.

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

Purchasing a put option gives a Fund the right to sell, and obligates the writer
to buy, the underlying security at the exercise price at any time during the
option period. This hedge protection is provided during the life of the put
option since the Fund, as holder of the put option, can sell the underlying
security at the put exercise price regardless of any decline in the underlying
security's market price.

In order for a put option to be profitable, the market price of the underlying
security must decline sufficiently below the exercise price to cover the premium
and transaction costs. By using put options in this manner, a Fund will reduce
any profit it might otherwise have realized in the underlying security by the
premium paid for the put option and by transaction costs.

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

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

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

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

Other Investment Companies. Certain emerging markets have restrictions that
preclude or limit direct foreign investment in the securities of their
companies. However, indirect foreign investment is permitted in certain emerging
markets through governmentally authorized investment vehicles or companies,
including closed-end investment companies, which may be acquired at prices in
excess of their net asset values. In accordance with the 1940 Act, each Fund may
invest up to 10% of its assets in shares of other investment companies. If a
Fund invests in other investment companies, shareholders would bear not only
their proportionate share of that Fund's expenses (including operating expenses
and advisory fees), but also similar expenses of the underlying investment
companies.

Short Sales. Each Fund may sell securities short "against-the-box." A short sale
"against-the-box" is a short sale in which a Fund owns an equal amount of the
securities sold short or securities convertible into or exchangeable without
payment of further consideration for securities of the same issuer as, and equal
in amount to, the securities sold short.

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

                                       7

<PAGE>

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

Illiquid Securities. Each Fund may invest up to 15% of its net assets in
illiquid securities, including restricted securities (i.e., securities not
readily marketable without registration under the Securities Act of 1933 (1933
Act)) and other securities that are not readily marketable. Each Fund does not
currently expect to invest more than 5% of its assets in such securities. A Fund
may purchase restricted securities that can be offered and sold to "qualified
institutional buyers" under Rule 144A of the 1933 Act, and, the Funds' Board of
Directors, may determine, when appropriate, that specific Rule 144A securities
are liquid and not subject to the 15% limitation on illiquid securities. Should
the Board of Directors make this determination, it will carefully monitor the
security (focusing on such factors, among others as trading activity and
availability of information) to determine that the Rule 144A security continues
to be liquid. It is not possible to predict with assurance exactly how the
market for Rule 144A securities will further evolve. This investment practice
could have the effect of increasing the level of illiquidity in a Fund, if and
to the extent that qualified institutional buyers become for a time uninterested
in purchasing Rule 144A securities.

Borrowing. Each Fund may borrow money only from banks and only for temporary or
emergency purposes (but not for the purchase of portfolio securities) in an
amount not in excess of 5% of each Fund's total assets (except the Emerging
Markets Growth Fund, where such borrowings will not exceed 10% of the Fund's
total assets) and will be made at prevailing interest rates. Each Fund's
borrowings are limited so that immediately after such borrowing the value of its
assets (including borrowings) less its liabilities (not including borrowings) is
at least three times the amount of the borrowings. Should a Fund, for any
reason, have borrowings that do not meet the above test, that Fund must reduce
its borrowings so as to meet the foregoing test within three business days.
Under these circumstances, a Fund may have to liquidate portfolio securities at
a time when it is disadvantageous to do so. Gains made with additional funds
borrowed will generally cause the net asset value of a Fund's shares to rise
faster than could be the case without borrowings. Conversely, if investment
results fail to cover the cost of borrowings, the net asset value of a Fund
could decrease faster than if there had been no borrowings.

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

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

Fund Policies

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

1.   As to 75% of the value of its total assets, invest more than 5% of its
     total assets, at market value, in the securities of any one issuer (except
     securities issued or guaranteed by the US Government, its agencies or
     instrumentalities).

2.   Invest more than 25% of its total assets, at market value, in the
     securities of issuers principally engaged in the same industry (except
     securities issued or guaranteed by the US Government, its agencies or
     instrumentalities).

3.   Own more than 10% of the outstanding voting securities of any issuer, or
     more than 10% of any class of securities of one issuer.

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

5.   Purchase securities of open-end or closed-end investment companies, except
     as permitted by the Investment Company Act of 1940, as amended, and other
     applicable law or for the purpose of hedging the Fund's obligations under
     the Deferred Compensation Plan for Directors.

6.   Invest in warrants if, at the time of acquisition, the investment in
     warrants, valued at the lower of cost or market value, would exceed 5% of
     the Fund's net assets. For purposes of this restriction, warrants acquired
     by a Fund in units or attached to securities may be deemed to have been
     purchased without cost.

7.   Make loans of money or securities other than (a) through the purchase of
     securities in accordance with a Fund's investment objective, (b) through
     repurchase agreements and (c) by lending portfolio securities in an amount
     not to exceed 33 1/3% of its total assets.

8.   Issue senior securities or borrow money except from banks and then in
     amounts not in excess of 5% (10% for Emerging Markets Growth Fund) of its
     total assets, as described above.

9.   Buy any securities or other property on margin (except for such short-term
     credits as are necessary for the clearance of transactions).

10.  Invest in companies for the purpose of exercising control or management.

11.  Underwrite securities of other issuers except to the extent that a Fund may
     be deemed an underwriter when purchasing or selling portfolio securities.

12.  Purchase or retain securities of any issuer (other than the shares of the
     Fund) if to the Fund's knowledge, those officers and directors of the Fund
     and the officers and directors of the investment manager or subadviser, who
     individually own beneficially more than 1/2 of 1% of the outstanding
     securities of such issuer, together own beneficially more than 5% of such
     outstanding securities.

13.  Purchase or sell real estate (although it may purchase securities secured
     by real estate or interests therein, or issued by companies or investment
     trusts that invest in real estate or interests therein).

14.  Make short sales except short sales against-the-box.

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

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

Temporary Defensive Position


In an attempt to respond to adverse market, economic, political, or other
conditions, the Fund may invest up to 100% of its assets in cash or cash
equivalents, including, but not limited to, prime commercial paper, bank
certificates of deposit, bankers' acceptances, or repurchase agreements for such
securities, and securities of the US Government and its agencies and
instrumentalities, as well as cash and cash equivalents denominated in foreign
currencies. The Fund's investments in foreign cash equivalents will be limited
to those that, in the opinion of the investment manager, equate generally to the
standards established for US cash equivalents. Investments in bank obligations
will be limited at the time of investment to the obligations of the 100 largest
domestic banks in terms of assets which are subject to regulatory supervision by
the US Government or state governments, and the obligations of the 100 largest
foreign banks in terms of assets with branches or agencies in the United States.


Portfolio Turnover

A Fund's portfolio turnover rate is calculated by dividing the lesser of
purchases or sales of portfolio securities for the fiscal year by the monthly
average of the value of the portfolio securities owned during the fiscal year.
Securities whose maturity or expiration date at the time of acquisition were one
year or less are excluded from the calculation. The Funds' portfolio turnover
rates for the fiscal years ended October 31, 1998 and 1997 were:

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

(2)  The Seligman Group of investment companies consists of eighteen investment
     companies.

(d)  Deferred.

Seligman Henderson Global Fund Series, Inc. has a compensation arrangement under
which outside directors may elect to defer receiving their fees. Seligman
Henderson Global Fund Series, Inc. has adopted a Deferred Compensation Plan
under which a director who has elected deferral of his or her fees may choose a
rate of return equal to either (1) the interest rate on short-term Treasury
bills, or (2) the rate of return on the shares of any of the investment
companies advised by J. & W. Seligman & Co. Incorporated, as designated by the
director. The cost of such fees and earnings is included in directors' fees and
expenses, and the accumulated balance thereof is included in other liabilities
in the Funds' financial statements. The total amount of deferred compensation
(including earnings) payable in respect of the Funds to Mr. Whitson as of
October 31, 1998 was $22,159.

Messrs. Merow and Pitney no longer defer current compensation; however, they
have accrued deferred compensation in the amounts of $12,364 and $1,501,
respectively, as of October 31, 1998.

The Funds may, but are not obligated to, purchase shares of the Seligman Group
of investment companies to hedge their obligations in connection with the
Deferred Compensation Plan.

include lineal descendants and lineal ancestors, siblings (and their spouses and
children) and any company or organization controlled by any of the foregoing.

account managed or advised by J. & W. Seligman & Co. Incorporated or any

     *    For the period 5/28/96 (commencement of operations) to 10/31/96.

     **   During the period, Seligman and/or Seligman Henderson Co., the prior
          subadviser, at their discretion, elected to waive a portion of their
          fees.

Under a Subadvisory Agreement dated July 1, 1998, Henderson Investment
Management Limited (HIML) furnishes investment advice, research and assistance
with respect to each Fund's non-US investments.

HIML, headquartered in the United Kingdom, was incorporated in 1984 and is a
registered investment adviser under the Investment Advisers Act of 1940. HIML is
a wholly owned subsidiary of Henderson plc. Henderson plc is a subsidiary of AMP
Limited, an Australian life insurance and financial services

company. Henderson plc, headquartered in London, is one of the largest money
managers in Europe. See Appendix C for further history of Henderson plc.

HIML receives a fee from Seligman, in respect of each Fund, based on the
"applicable percentage" of the average monthly assets of such Fund under its
supervision. The "applicable percentage" is an annual rate of 0.90% for the
period July 1, 1998 to June 30, 1999; 0.70% for the period July 1, 1999 to June
30, 2000; and 0.50% thereafter. The Subadvisory Agreement provides that it will
continue until December 31, 1999; and, thereafter, is subject to the annual
approval of the Funds' Board of Directors.

Each Fund pays all of its expenses, other than those assumed by Seligman or
HIML, including brokerage commissions, administration, shareholder services and
distribution fees, fees and expenses of independent attorneys and auditors,
taxes and governmental fees, including fees and expenses of qualifying the Funds
and their shares under federal and state securities laws, cost of stock
certificates and expenses of repurchase or redemption of shares, expenses of
printing and distributing reports, notices and proxy materials to shareholders,
expenses of printing and filing reports and other documents with governmental
agencies, expenses of shareholders' meetings, expenses of corporate data
processing and related services, shareholder record keeping and shareholder
account services, fees and disbursements of transfer agents and custodians,
expenses of disbursing dividends and distributions, fees and expenses of
directors of the Funds not employed by or serving as a director of Seligman or
its affiliates, insurance premiums and extraordinary expenses such as litigation
expenses. These expenses are allocated between each Fund and between the classes
of each Fund in a manner determined by the Board of Directors to be fair and
equitable.

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

The Management Agreement was initially approved by the Board of Directors at a
meeting held on March 19, 1992 and by the shareholders on May 20, 1993. The
Management Agreement will continue in effect until December 31 of each year if
(1) such continuance is approved in the manner required by the 1940 Act (i.e.,
by a vote of a majority of the Board of Directors or of the outstanding voting
securities of each Fund and by a vote of a majority of the Directors who are not
parties to the Management Agreement or interested persons of any such party) and
(2) Seligman has not notified the Funds 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 a Fund, without penalty, on 60 days' written notice to Seligman
and will terminate automatically in the event of its assignment. Seligman
Henderson Global Fund Series, Inc. has agreed to change its name upon
termination of the Management Agreement if continued use of the name would cause
confusion in the context of Seligman's business.

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

                                       18

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

Officers, directors, and employees are required, except under very limited
circumstances, to engage in personal securities transactions through Seligman's
order desk. The order desk maintains a list of securities that may not be
purchased due to a possible conflict with clients. All officers, directors and
employees are also required to disclose all securities beneficially owned by
them on December 31 of each year.

Rule 12b-1 Plans

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


Under its 12b-1 Plan, each Fund may pay to Seligman Advisors an administration,
shareholder services and distribution fee in respect of the Fund's Class A,
Class B, Class C, and Class D shares. Payments under the 12b-1 Plan may include,
but are not limited to: (1) compensation to securities dealers and other
organizations (Service Organizations) for providing distribution assistance with
respect to assets invested in the Fund; (2) compensation to Service
Organizations for providing administration, accounting and other shareholder
services with respect to Fund shareholders; and (3) otherwise promoting the sale
of shares of the Fund, including paying for the preparation of advertising and
sales literature and the printing and distribution of such promotional materials
and prospectuses to prospective investors and defraying

                                       20

<PAGE>


Seligman Advisors' costs incurred in connection with its marketing efforts with
respect to shares of the Fund. Seligman, in its sole discretion, may also make
similar payments to Seligman Advisors from its own resources, which may include
the management fee that Seligman receives from each Fund. Payments made by each
Fund under its Rule 12b-1 Plan are intended to be used to encourage sales of
such Fund, as well as to discourage redemptions.


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

Class A

Under its 12b-1 Plan, each Fund, with respect to Class A shares, pays quarterly
to Seligman Advisors a service fee at an annual rate of up to .25% of the
average daily net asset value of the Class A shares. These fees are used by
Seligman Advisors exclusively to make payments to Service Organizations which
have entered into agreements with Seligman Advisors. Such Service Organizations
receive from Seligman Advisors a continuing service fee of up to .25% on an
annual basis, payable quarterly, of the average daily net assets of Class A
shares attributable to the particular Service Organization for providing
personal service and/or maintenance of shareholder accounts. The fee payable to
Service Organizations from time to time shall, within such limits, be determined
by the Directors. The Funds are not obligated to pay Seligman Advisors for any
such costs it incurs in excess of the fee described above. No expenses incurred
in one fiscal year by Seligman Advisors with respect to Class A shares of a Fund
may be paid from Class A 12b-1 fees received from that Fund in any other fiscal
year. If a Fund's 12b-1 Plan is terminated in respect of Class A shares, no
amounts (other than amounts accrued but not yet paid) would be owed by that Fund
to Seligman Advisors with respect to Class A shares. The total amount paid by
each Fund to Seligman Advisors in respect of Class A shares for the fiscal year
ended October 31, 1998 was as follows:

                                                    Total          % of Average

Class B


Under its 12b-1 Plan, each Fund, with respect to Class B shares, pays monthly a
12b-1 fee at an annual rate of up to 1% of the average daily net asset value of
the Class B shares. The fee is comprised of (1) a distribution fee equal to .75%
per annum, which is paid directly to a third party, FEP Capital, L.P., to
compensate it for having funded, at the time of sale of Class B shares (i) a 4%
sales commission to Service Organizations and (ii) a payment of up to .25% of
sales to Seligman Advisors to help defray its costs of distributing Class B
shares; and (2) a service fee of up to .25% per annum which is paid to Seligman
Advisors. The service fee is used by Seligman Advisors exclusively to make
payments to Service Organizations which have entered into agreements with
Seligman Advisors. Such Service Organizations receive from Seligman Advisors a
continuing service fee of up to .25% on an annual basis, payable quarterly, of
the average daily net assets of Class B shares attributable to the particular
Service Organization for providing personal service and/or maintenance of
shareholder accounts. The amounts expended by Seligman Advisors or FEP Capital,
L.P. in any one year upon the initial purchase of Class B shares of a Fund may
exceed the 12b-1 fees paid by that Fund in that year. Each Fund's 12b-1 Plan
permits expenses incurred in respect of Class B shares in one fiscal year to be
paid from Class B 12b-1 fees received from the Fund in any other fiscal year;
however, in any fiscal year the Funds are not obligated to pay any 12b-1 fees in
excess of the fees described above. Seligman Advisors and FEP Capital, L.P. are
not reimbursed for expenses which exceed such fees. If a Fund's 12b-1 Plan is
terminated


                                       21

<PAGE>

in respect of Class B shares, no amounts (other than amounts accrued but not yet
paid) would be owed by that Fund to Seligman Advisors or FEP Capital, L.P. with
respect to Class B shares. The total amount paid by each Fund in respect of
Class B shares for the fiscal year ended October 31, 1998, was equal to 1% per
annum of the average daily net assets of Class B shares, as follows:

Class C


Under the 12b-1 Plan, each Fund, with respect to Class C shares, pays monthly to
Seligman Advisors a 12b-1 fee at an annual rate of up to 1% of the average daily
net asset value of the Class C shares. The fee is used by Seligman Advisors as
follows: During the first year following the sale of Class C shares, a
distribution fee of .75% of the average daily net assets attributable to Class C
shares is used, along with any CDSC proceeds during the first eighteen months,
to (1) reimburse Seligman Advisors for its payment at the time of sale of Class
C shares of a 1.25% sales commission to Service Organizations, and (2) pay for
other distribution expenses, including paying for the preparation of advertising
and sales literature and the printing and distribution of such promotional
materials and prospectuses to prospective investors and other marketing costs of
Seligman Advisors. In addition, during the first year following the sale of
Class C shares, a service fee of up to .25% of the average daily net assets
attributable to such Class C shares is used to reimburse Seligman Advisors for
its prepayment to Service Organizations at the time of sale of Class C shares of
a service fee of .25% of the net asset value of the Class C shares sold (for
shareholder services to be provided to Class C shareholders over the course of
the one year immediately following the sale). The payment of service fees to
Seligman Advisors is limited to amounts Seligman Advisors actually paid to
Service Organizations at the time of sale as service fees. After the initial
one-year period following a sale of Class C shares, the entire 12b-1 fee
attributable to such Class C shares is paid to Service Organizations for
providing continuing shareholder services and distribution assistance in respect
of the Funds. The Funds do not pay any 12b-1 fees in respect of Class C shares
for the fiscal year ended September 30, 1998 because no Class C shares were
issued or outstanding during such period.


Class D


Under its 12b-1 Plan, each Fund, with respect to Class D shares, pays monthly to
Seligman Advisors a 12b-1 fee at an annual rate of up to 1% of the average daily
net asset value of Class D shares. This fee is used by Seligman Advisors, as
follows: During the first year following the sale of Class D shares, a
distribution fee of .75% of the average daily net assets attributable to such
Class D shares is used, along with any CDSC proceeds, to (1) reimburse Seligman
Advisors for its payment at the time of sale of Class D shares of a .75% sales
commission to Service Organizations, and (2) pay for other distribution
expenses, including paying for the preparation of advertising and sales
literature and the printing and distribution of such promotional materials and
prospectuses to prospective investors and other marketing costs of Seligman
Advisors. In addition, during the first year following the sale of Class D
shares, a service fee of up to .25% of the average daily net assets attributable
to such Class D shares is used to reimburse Seligman Advisors for its prepayment
to Service Organizations at the time of sale of Class D shares of a service fee
of .25% of the net asset value of the Class D shares sold (for shareholder
services to be provided to Class D shareholders over the course of the one year
immediately following the sale). The payment of service fees to Seligman
Advisors is limited to amounts Seligman Advisors actually paid to Service
Organizations at the time of sale as service fees. After the initial one-year
period following a sale of Class D shares, the entire 12b-1 fee attributable to
such Class D shares is paid to Service Organizations for providing continuing
shareholder services and distribution assistance in respect of each Fund. The
total amount paid by each Fund in respect of Class D shares for the fiscal year
ended October 31, 1998 was equal to 1% per annum of the average daily net assets
of Class D shares, as follows:

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

As of September 30, 1998 (the most recent calendar quarter for which such
information was reported), Seligman Advisors has incurred the following amounts

The 12b-1 Plan with respect to the International Fund was originally approved on
July 15, 1993 by the Board of Directors, including a majority of the Directors
who are not "interested persons" (as defined in the 1940 Act) and who have no
direct or indirect financial interest in the operation of the Fund (Qualified
Directors) and by the shareholders of such Fund on September 21, 1993. The 12b-1
Plan with respect to the Emerging Markets Growth Fund was originally approved on
March 21, 1996 by the Board of Directors, including a majority of the Qualified
Directors, and by the sole shareholder of each Class of shares of the Fund on
May 10, 1996. The 12b-1 Plan with respect to the Global Growth Opportunities
Fund was originally approved on September 21, 1995 by the Board of Directors,
including a majority of the Qualified Directors, and by the sole shareholder of
such Fund on October 30, 1995. The 12b-1 Plan with respect to the Global Smaller
Companies Fund was originally approved on July 16, 1992 by the Board of
Directors, including a majority of the Qualified Directors. Amendments to the
12b-1 Plan in respect of Class D shares of the Global Smaller Companies Fund
were approved by the Board of Directors of the Fund, including a majority of the
Qualified Directors, on March 18, 1993 and the amended 12b-1 Plan was approved
by the shareholders of the Global Smaller Companies Fund on May 20, 1993. The
12b-1 Plan with respect to the Global Technology Fund was originally approved on
March 17, 1994 by the Board of Directors, including a majority of the Qualified
Directors, and by the sole shareholder of such Fund on that date. The 12b-1
Plans were approved in respect of the Class B shares of each Fund other than the
Emerging Markets Growth Fund on March 21, 1996 by the Board of Directors,
including a majority of the Qualified Directors, and by the sole shareholder of
each such Fund's Class B shares on that date, and became effective in respect of
such Class B shares on April 22, 1996. In addition, the 12b-1 Plans were
approved with respect of Class C shares of each Fund on May 20, 1999 by the
Directors, including a majority of the Qualified Directors, and became effective
in respect of each Fund's Class C shares on June 1, 1999.


The 12b-1 Plans will continue in effect through December 31 of each year so long
as such continuance is approved annually by a majority vote of both the
Directors and the Qualified Directors, cast in person at a meeting called for
the purpose of voting on such approval. No material amendment to the 12b-1 Plans
may be made except by a majority of both the Directors and Qualified Directors.
The 12b-1 Plans 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 such Class. If the amount payable in
respect of Class A shares under a Fund's 12b-1 Plan is proposed to be increased
materially, the Fund will either (i) permit holders of Class B shares to vote as
a separate class on the proposed increase or (ii) establish a new class of
shares subject to the same payment under the 12b-1 Plan as existing Class A
shares, in which case Class B shares will thereafter convert into the new class
instead of into Class A shares.

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

Seligman Services acts as a broker/dealer of record for shareholder accounts
that do not have a designated financial advisor. As such, it receives
compensation from each Fund pursuant to its 12b-1 Plan for providing personal
services and account maintenance to such accounts and other distribution
services. For

                    Brokerage Allocation and Other Practices

Brokerage Transactions

Seligman and HIML will seek the most favorable price and execution in the
purchase and sale of portfolio securities of each Fund. When two or more of the
investment companies in the Seligman Group or other investment advisory clients
of Seligman or HIML desire to buy or sell the same security at the same time,
the securities purchased or sold are allocated by Seligman or HIML in a manner
believed to be equitable to each. There may be possible advantages or
disadvantages of such transactions with respect to price or the size of
positions readily obtainable or saleable.

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

For the fiscal years ended October 31, 1998, 1997, and 1996, the Funds paid
total brokerage commissions to others for execution, research and statistical
services in the following amounts:

Commissions

For the fiscal years ended October 31, 1998, 1997, and 1996, the Funds did not
execute any portfolio transactions with, and therefore did not pay any
commissions to, any broker affiliated with the Funds, Seligman, HIML, or
Seligman Advisors.

Brokerage Selection

Consistent with seeking the most favorable price and execution when buying or
selling portfolio securities, Seligman may give consideration to the research,
statistical, and other services furnished by brokers or dealers to Seligman for
its use, as well as the general attitude toward and support of investment
companies demonstrated by such brokers or dealers. Such services include
supplemental investment research, analysis, and reports concerning issuers,
industries, and securities deemed by Seligman to be beneficial to the Funds. In
addition, Seligman is authorized to place orders with brokers who provide
supplemental investment and market research and security and economic analysis
although the use of such brokers may result in a higher brokerage charge to a
Fund than the use of brokers selected solely on the basis of seeking

                                       25

<PAGE>

the most favorable price and execution and although such research and analysis
may be useful to Seligman in connection with its services to clients other than
the Funds.

Directed Brokerage

During the Funds' fiscal year ended October 31, 1998, neither the Funds,
Seligman, nor HIML directed any of the Funds' brokerage transactions to a broker
because of research services provided.

Regular Broker-Dealers

During the Funds' fiscal year ended October 31, 1998, the Funds did not acquire
securities of any of its regular brokers or dealers (as defined in Rule 10b-1
under the 1940 Act) or of their parents.

                       Capital Stock and Other Securities

Capital Stock


Seligman Henderson Global Fund Series, Inc. is authorized to issue 2,000,000,000
shares of common stock, each with a par value of $.001 each, divided into five
different series (which represent each of the Funds). Each Fund has four
classes, designated Class A common stock, Class B common stock, Class C common
stock, and Class D common stock. Each share of a Fund's Class A, Class B, Class
C, and Class D common stock is equal as to earnings, assets, and voting
privileges, except that each class bears its own separate distribution and,
potentially, certain other class expenses and has exclusive voting rights with
respect to any matter to which a separate vote of any class is required by the
1940 Act or Maryland law. Seligman Henderson Global Fund Series, Inc. has
adopted a multiclass plan pursuant to Rule 18f-3 under the 1940 Act permitting
the issuance and sale of multiple classes of common stock. In accordance with
the Articles of Incorporation, the Board of Directors may authorize the creation
of additional classes of common stock with such characteristics as are permitted
by the multiclass plan and Rule 18f-3. The 1940 Act requires that where more
than one class exists, each class must be preferred over all other classes in
respect of assets specifically allocated to such class. All shares have
noncumulative voting rights for the election of directors. Each outstanding
share is fully paid and non-assessable, and each is freely transferable. There
are no liquidation, conversion, or preemptive rights.


Other Securities

Seligman Henderson Global Fund Series, Inc. has no authorized securities other
than common stock.

                   Purchase, Redemption, and Pricing of Shares

Purchase of Shares

Class A

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


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


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

The Right of Accumulation allows an investor to combine the amount being
invested in Class A shares of a Fund and shares of the other Seligman mutual
funds sold with an initial sales charge with the total net asset value of shares
of those mutual funds already owned that were sold with an initial sales charge
and the total net asset value of shares of Seligman Cash Management Fund which
were acquired through an

                                       26

<PAGE>

exchange of shares of another Seligman mutual fund on which there was an initial
sales charge at the time of purchase to determine reduced sales charges in
accordance with the schedule in the prospectus. The value of the shares owned,
including the value of shares of Seligman Cash Management Fund acquired in an
exchange of shares of another Seligman mutual fund on which there was an initial
sales charge at the time of purchase will be taken into account in orders placed
through a dealer, however, only if Seligman Advisors is notified by an investor
or a dealer of the amount owned by the investor at the time the purchase is made
and is furnished sufficient information to permit confirmation.

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

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

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

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

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


Eligible Employee Benefit Plans. The table of sales charges in the Prospectus
applies to sales to "eligible employee benefit plans," except that the Fund may
sell shares at net asset value to "eligible employee benefit plans" which have
at least (1) $500,000 invested in the Seligman Group of mutual funds or (2) 50
eligible employees to whom such plan is made available. Such sales must be made
in connection with a payroll deduction system of plan funding or other systems
acceptable to Seligman Data Corp., the Funds' shareholder service agent.
"Eligible employee benefit plan" means any plan or arrangement, whether or not
tax qualified, which provides for the purchase of Fund shares. Sales of shares
to such plans must be made in connection with a payroll deduction system of plan
funding or other system acceptable to Seligman Data Corp. Section 403(b) Plans
sponsored by public educational institutions are not eligible for net asset
value purchases based on the aggregate investment made by the plan or member of
eligible employees.


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

                                       27

<PAGE>


Further Types of Reductions. Class A shares may also be issued without an
initial sales charge in the following instances:

(1)  to any registered unit investment trust which is the issuer of periodic
     payment plan certificates, the net proceeds of which are invested in Fund
     shares;

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

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

(4)  to financial institution trust departments;

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

(6)  to accounts of financial institutions or broker/dealers that charge account
     management fees, provided Seligman or one of its affiliates has entered
     into an agreement with respect to such accounts;

(7)  pursuant to sponsored arrangements with organizations which make
     recommendations to, or permit group solicitations of, its employees,
     members or participants in connection with the purchase of shares of the
     Fund;

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

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

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

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

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

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


Class B

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

                                       28

<PAGE>


Years Since Purchase                                        CDSC

Less than 1 year ..........................................   5%
1 year or more but less than 2 years ......................   4%
2 years or more but less than 3 years .....................   3%
3 years or more but less than 4 years .....................   3%
4 years or more but less than 5 years .....................   2%
5 years or more but less than 6 years .....................   1%
6 years or more ...........................................   0%


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

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

Class C

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


Class D

Class D shares may be purchased at a price equal to the next determined net
asset value, without an initial sales charge. However, Class D shares are
subject to a CDSC of 1% if the shares are redeemed within one year of purchase,
charged as a percentage of the current net asset value or the original purchase
price, whichever is less. Unlike Class B shares, Class D shares do not
automatically convert to Class A shares after eight years.


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

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


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

(2)  in connection with (1) distributions from retirement plans qualified under
     Section 401(a) of the Internal Revenue Code when such redemptions are
     necessary to make distributions to plan participants (such payments
     include, but are not limited to, death, disability, retirement, or
     separation of service), (2) distributions from a custodial account under
     Section 403(b)(7) of the Internal Revenue Code or an IRA due to death,
     disability, minimum distribution requirements after attainment of age 70
     1/2 or, for

                                       29

<PAGE>

     accounts established prior to January 1, 1998, attainment of age 59 1/2,
     and (3) a tax-free return of an excess contribution to an IRA;

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

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

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

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


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


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

Fund Reorganizations


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


Offering Price


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

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

                                       30

<PAGE>

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 not recent sales transactions are valued
based on quotations provided by primary market maker in such securities. Other
securities not listed on an exchange or securities market, or securities in
which there were no transactions, are valued at the average of the most recent
bid and asked price, except in the case of open short positions where the asked
price is available. Any securities or other assets for which recent market
quotations are not readily available are valued at fair value as determined in
accordance with procedures approved by the Board of Directors. Short-term
obligations with less than sixty days remaining to maturity are generally valued
at amortized cost. Short-term obligations with more than sixty days remaining to
maturity will be valued at current market value until the sixtieth day prior to
maturity, and will then be valued on an amortized cost basis based on the value
on such date unless the Board determines that this amortized cost value does not
represent fair market value.

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 regular trading on the NYSE. The
values of such securities used in computing the net asset value of the shares of
each Fund are determined as of such times. Foreign currency exchange rates are
also generally determined prior to the close of regular trading on the NYSE.

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


Specimen Price Make-Up

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

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

(2)  Class B shares are subject to a CDSC, declining from 5% in the first year
     after purchase to 0% after six years. Class D shares are also subject to a
     1% CDSC if you redeem your shares within one year of purchase.


Redemption in Kind

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

                              Taxation of the Funds

Foreign Income Taxes. Investment income received by the Fund from sources within
foreign countries may be subject to foreign income taxes withheld at 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 amount of each Fund's assets to be invested within various
countries is not known.

US Federal Income Taxes. Each Fund is qualified and intends to continue to
qualify for each taxable year for tax treatment as a "regulated investment
company" under the Internal Revenue Code. Qualification relieves a Fund of
Federal income tax liability on that part of its net ordinary income and net
realized capital gains which it pays out to its shareholders. Such qualification
does not, of course, involve governmental supervision of management or
investment practices or policies. Investors should consult their own counsel for
a complete understanding of the requirements a Fund must meet to qualify for
such treatment. The information set forth in the Prospectus and the following
discussion relate solely to the US Federal income taxes on dividends and
distributions by a Fund and assumes that each Fund qualifies as a regulated
investment company. Investors should consult their own counsel for further
details, including their possible entitlement to foreign tax credits that might
be "passed through" to them under the rules described below, and the application
of state and local tax laws to his or her particular situation.

Each Fund intends to declare and distribute dividends in the amounts and at the
times necessary to avoid the application of the 4% Federal excise tax imposed on
certain undistributed income of regulated investment companies. Each Fund will
be required to pay the 4% excise tax to the extent it does not distribute to its
shareholders during any calendar year at least 98% of its ordinary income for
the calendar year plus 98% of its capital gain net income for the twelve months
ended October 31 of such year. Certain distributions of the Fund which are paid
in January of a given year but are declared in the prior October, November or
December to shareholders of record as of a specified date during such a month
will be treated as having been distributed to shareholders and will be taxable
to shareholders as if received in December.

                                       32

<PAGE>


Dividends of net ordinary income and distributions of any net realized
short-term capital gain are taxable to shareholders as ordinary income. Since
each Fund expects to derive a substantial portion of its gross income (exclusive
of capital gains) from sources other than qualifying dividends, it is expected
that only a portion of each Fund's dividends or distributions will qualify for
the dividends received deduction for corporations.

The excess of net long-term capital gains over the net short-term capital losses
realized and distributed by each Fund to its shareholders will be taxable to the
shareholders as long-term capital gains, irrespective of the length of time a
shareholder may have held Fund shares. Individual shareholders will be subject
to federal income tax on net capital gain at a maximum rate of 20% in respect of
shares held for more than one year. Net capital gain of a corporate shareholder
is taxed at the same rate as ordinary income. Any dividend or distribution
received by a shareholder on shares of a Fund shortly after the purchase of such
shares will have the effect of reducing the net asset value of such shares by
the amount of such dividend or distribution. Furthermore, such dividend or
distribution, although in effect a return of capital, would be taxable to the
shareholder as described above. If a shareholder has held shares in a Fund for
six months or less and during that period has received a distribution taxable to
the shareholder as a long-term capital gain, any loss recognized by the
shareholder on the sale of those shares during that period will be treated as a
long-term capital loss to the extent of the distribution.

Dividends and distributions are taxable in the manner discussed regardless of
whether they are paid to the shareholder in cash or are reinvested in additional
shares of a Fund's common stock.

Income received by a Fund from sources within various foreign countries may be
subject to foreign income tax. If more than 50% of the value of a Fund's total
assets at the close of its taxable year consists of the stock or securities of
foreign corporations, such Fund may elect to "pass through" to its shareholders
the amount of foreign income taxes paid by such Fund. Pursuant to such election,
shareholders would be required: (i) to include in gross income, even though not
actually received, their respective pro-rata shares of a Fund's gross income
from foreign sources; and (ii) either to deduct their pro-rata share of foreign
taxes in computing their taxable income, or to use such share as a foreign tax
credit against Federal income tax (but not both). No deduction for foreign taxes
could be claimed by a shareholder who does not itemize deductions.

Shareholders who choose to utilize a credit (rather than a deduction) for
foreign taxes will be subject to the limitation that the credit may not exceed
the shareholder's US tax (determined without regard to the availability of the
credit) attributable to his or her total foreign source taxable income. For this
purpose, the portion of dividends and distributions paid by a Fund from its
foreign source income will be treated as foreign source income. Each Fund's
gains from the sale of securities will generally be treated as derived from US
sources, however, and certain foreign currency gains and losses likewise will be
treated as derived from US sources. The limitation on the foreign tax credit is
applied separately to foreign source "passive income," such as the portion of
dividends received from a Fund which qualifies as foreign source income. In
addition, the foreign tax credit is allowed to offset only 90% of the
alternative minimum tax imposed on corporations and individuals. Because of
these limitations, shareholders may be unable to claim a credit for the full
amount of their proportionate shares of the foreign income taxes paid by a Fund.

Each Fund intends for each taxable year to meet the requirements of the Code to
"pass through" to its shareholders foreign income taxes paid, but there can be
no assurance that a Fund will be able to do so. Each shareholder will be
notified within 60 days after the close of each taxable year of each Fund
whether the foreign taxes paid by such Fund will "pass through" for that year,
and, if so, the amount of each shareholder's pro-rata share (by country) of (i)
the foreign taxes paid, and (ii) such Fund's gross income from foreign sources.
Of course, shareholders who are not liable for Federal income taxes, such as
retirement plans qualified under Section 401 of the Code, will not be affected
by any such "pass through" of foreign tax credits.

                                       33

<PAGE>


Investments in Passive Foreign Investment Companies. If a Fund purchases shares
in certain foreign investment entities, referred to as "passive foreign
investment companies," the Fund itself may be subject to US Federal income tax,
and an additional charge in the nature of interest, on a portion of any "excess
distribution" from such company or gain from the disposition of such shares,
even if the distribution or gain is paid by such Fund as a dividend to its
shareholders. If a Fund were able and elected to treat a passive foreign
investment company as a "qualified electing fund," in lieu of the treatment
described above, such Fund would be required each year to include in income, and
distribute to shareholders in accordance with the distribution requirements set
forth above, its pro rata share of the ordinary earnings and net capital gains
of the company, whether or not distributed to such Fund.

Certain Foreign Currency Transactions. Gains or losses attributable to foreign
currency contracts, or to fluctuations in exchange rates that occur between the
time a Fund accrues interest or other receivables or accrues expenses or other
liabilities denominated in a foreign currency and the time the Fund actually
collects such receivables or pays such liabilities are treated as ordinary
income or ordinary loss. Similarly, gains or losses on disposition of debt
securities denominated in a foreign currency attributable to fluctuations in the
value of the foreign currency between the date of acquisition of the security
and the date of disposition also are treated as ordinary gain or loss. These
gains or losses increase or decrease the amount of a Fund's net investment
income available to be distributed to its shareholders as ordinary income.

Options Transactions. A special "marked-to-market" system governs the taxation
of "section 1256 contracts," which include certain listed options. Each Fund may
invest in such section 1256 contracts. In general, gain or loss on section 1256
contracts will be taken into account for tax purposes when actually realized. In
addition, any section 1256 contracts held at the end of a taxable year will be
treated as sold at fair market value (that is, marked-to-market), and the
resulting gain or loss will be recognized for tax purposes. In general, gain or
loss recognized by a Fund on the actual or deemed disposition of a section 1256
contract will be treated as 60% long-term and 40% short-term capital gain or
loss, regardless of the period of time the section 1256 contract is actually
held by such Fund. Each Fund can elect to exempt its section 1256 contracts
which are part of a "mixed" straddle from the application of section 1256.

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

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

Distribution of Securities

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

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

Other Payments

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

Seligman Advisors shall also pay broker/dealers, from its own resources, a fee
on assets of certain investments in Class A shares of the Seligman mutual funds
participating in an "eligible employee benefit plan" that are attributable to
the particular broker/dealer. The shares eligible for the fee are those on which
an initial sales charge was not paid because either the participating eligible
employee benefit plan has at least (1) $500,000 invested in the Seligman mutual
funds or (2) 50 eligible employees to whom such plan is made available. Class A
shares representing only an initial purchase of Seligman Cash Management Fund
are not eligible for the fee. Such shares will become eligible for the fee once
they are exchanged for shares of another Seligman mutual fund. The payment is
based on cumulative sales for each Plan during a single calendar year, or
portion thereof. The payment schedule, for each calendar year, is as follows:
1.00% of sales up to but not including $2 million; .80% of sales from $2 million
up to but not including $3 million; .50% of sales from $3 million up to but not
including $5 million; and .25% of sales from $5 million and above.

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

                         Calculation of Performance Data

Class A

The average annual total returns for the one-year and five-year periods ended
October 31, 1998 and for the period April 7, 1992 (inception) through October
31, 1998 for the Class A shares of the International Fund were 1.46%, 6.12% and
9.34%, respectively.

The average annual total returns for the one-year period ended October 31, 1998
and for the period May 28, 1996 (inception) through October 31, 1998 for the
Class A shares of the Emerging Markets Growth Fund were (32.81%) and (14.14%),
respectively.

The average annual total returns for the one-year period ended October 31, 1998
and for the period November 1, 1995 (inception) through October 31, 1998 for the
Class A shares of the Global Growth Opportunities Fund were 4.31% and 10.34%,
respectively.

The average annual total returns for the one-year and five-year periods ended
October 31, 1998 and for the period September 9, 1992 (inception) through
October 31, 1998 for the Class A shares of the Global Smaller Companies Fund
were (10.30)%, 10.41% and 14.49%, respectively.

The average annual total returns for the one-year period ended October 31, 1998
and for the period May 23, 1994 (inception) through October 31, 1998 for the
Class A shares of the Global Technology Fund were (5.53)% and 18.93%,
respectively.

The average annual total returns for each Fund's Class A shares were computed by
assuming a hypothetical initial investment of $1,000 in Class A shares of the
Fund, subtracting the maximum sales charge of 4.75% of public offering price,
and assuming that all dividends and distributions paid by the Fund's Class A
shares, if any, were reinvested over the relevant time period. It was then
assumed that at the end of each period, the entire amount was redeemed. The
average annual total return was then calculated by calculating the annual rate
required for the initial payment to grow to the amount which would have been
received upon such redemption (i.e., the average annual compound rate of
return).

Class B

The average annual total returns for the one-year period ended October 31, 1998
and for the period April 22, 1996 (inception) to October 31, 1998 for the Class
B shares of the International Fund were 0.62% and 3.00%, respectively.

The average annual total returns for the one-year period ended October 31, 1998
and for the period May 28, 1996 (inception) to October 31, 1998 for the Class B
shares of the Emerging Markets Growth Fund were (33.49)% and (14.10)%,
respectively.

The average annual total returns for the one-year period ended October 31, 1998
and for the period April 22, 1996 (inception) to October 31, 1998 for the Class
B shares of the Global Growth Opportunities Fund were 3.76% and 7.33%,
respectively.

The average annual total returns for the one-year period ended October 31, 1998
and for the period April 22, 1996 (inception) to October 31, 1998 for the Class
B shares of the Global Smaller Companies Fund were (11.01)% and (0.19)%,
respectively.

The average annual total returns for the one-year period ended October 31, 1998
and for the period April 22, 1996 (inception) to October 31, 1998 for the Class
B shares of the Global Technology Fund were (5.62)% and 8.69%, respectively.

The average annual total returns for each Fund's Class B shares were computed by
assuming a hypothetical initial investment of $1,000 in Class B shares of the
Fund, and assuming that all dividends and

                                       37

<PAGE>

distributions paid by the Fund's Class B shares, if any, were reinvested over
the relevant time period. It was then assumed that at the end of each period,
the entire amount was redeemed, subtracting the applicable CDSC.

Class D

The average annual total returns for the one-year and five-year periods ended
October 31, 1998 and for the period September 21, 1993 (inception) through
October 31, 1998 for the Class D shares of the International Fund were 4.53%,
6.29%, and 7.12%, respectively.

The average annual total returns for the one-year period ended October 31, 1998
and for the period May 28, 1996 (inception) through October 31, 1998 for the
Class D shares of the Emerging Markets Growth Fund were (30.69)% and (13.02)%,
respectively.

The average annual total returns for the one-year period ended October 31, 1998
and the period November 1, 1995 (inception) through October 31, 1998 for the
Class D shares of the Global Growth Opportunities Fund were 7.76% and 11.33%,
respectively.

The average annual total returns for the one-year and five-year periods ended
October 31, 1998 and for the period May 3, 1993 (inception) through October 31,
1998 for Class D shares of the Global Smaller Companies Fund were (7.43)%,
10.66% and 12.77%, respectively.

The average annual total returns for the one-year period ended October 31, 1998
and for the period May 23, 1994 (inception) through October 31, 1998 for the
Class D shares of the Global Technology Fund were (2.51)% and 19.25%,
respectively.

The average annual total returns for each Fund's Class D shares were computed by
assuming a hypothetical initial investment of $1,000 in Class D shares of the
Fund, and assuming that all dividends and distributions paid by the Fund's Class
D shares, if any, were reinvested over the relevant time period. It was then
assumed that at the end of each period, the entire amount was redeemed,
subtracting for the one-year period the 1% CDSC, if applicable.

The tables below illustrate the total returns on a $1,000 investment in each of
the Fund's Class A, Class B and Class D shares from the commencement of a Fund's
operations through October 31, 1998, assuming investment of all dividends and
capital gain distributions and deduction of any applicable sales charges or
CDSC. Average annual total returns are determined by calculating the annual rate
of return required for the initial $1,000 investment to grow to the amount which
would have been received upon redemption. (i.e., the average annual compound
rate of return).


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


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 any Fund today.

(2)  The "Value of Initial Investment" as of the date indicated reflects the
     effect of the maximum sales load or CDSC, if applicable, 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 of Investment" reflects the
     effect of the CDSC, if applicable, and assumes investment of all dividends
     and capital gain distributions.

(3)  "Total Return" for each class of shares of a 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 capital gain distributions
     that would have been paid during the period on such shares assuming that
     each dividend or capital gain 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 CDSC on Class B and 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. The International Fund's total return and average
     annual total return quoted from time to time through September 21, 1993 for
     Class A shares does not reflect the deduction of the administration,
     shareholder services and distribution fee effective on that date, which fee
     if reflected would reduce the performance quoted.

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

Seligman and/or the prior subadviser waived its fees and reimbursed certain
expenses during some of the periods above, which positively affected the
performance results presented.

Fund's Class A, Class B, Class C, and Class D shares, the Lipper analysis
assumes investment of all dividends and distributions paid but does not take
into account applicable sales charges. Each Fund may also refer in
advertisements in other promotional material to articles, comments, listings and
columns in the financial press pertaining to the Fund's performance. Examples of
such financial and other press publications include BARRON'S, BUSINESS WEEK,

A Fund's advertising or promotional material may make reference to the Fund's
"Beta," "Standard Deviation," or "Alpha." Beta measures the volatility of the
Fund, as compared to that of the overall market. Standard deviation measures how
widely the Fund's performance has varied from its average performance, and is an
indicator of the Fund's potential for volatility. Alpha measures the difference
between the returns of the Fund and the returns of the market, adjusted for
volatility.

                                   Appendix A

Moody's Investors Service, Inc.  ("Moody's")
Debt Securities

Aaa: Bonds which are rated Aaa are judged to be of the best quality. They carry
the smallest degree of investment risk. Interest payments are protected by a
large or by an exceptionally stable margin and principal is secure. While the
various protective elements are likely to change, such changes as can be
visualized are most unlikely to impair the fundamentally strong position of such
issues.

Aa: Bonds which are rated Aa are judged to be of high quality by all standards.
Together with the Aaa group they comprise what are generally known as high-grade
bonds. They are rated lower than Aaa bonds because margins of protection may not
be as large or fluctuation of protective elements may be of greater amplitude or
there may be other elements present which make the long-term risks appear
somewhat larger than in Aaa securities.

A: Bonds which are rated A possess many favorable investment attributes and are
to be considered as upper medium grade obligations. Factors giving security to
principal and interest are considered adequate but elements may be present which
suggest a susceptibility to impairment sometime in the future.

Baa: Bonds which are rated Baa are considered as medium grade obligations, i.e.,
they are neither highly protected nor poorly secured. Interest payments and
principal security appear adequate for the present but certain protective
elements may be characteristically lacking or may be unreliable over any great
length of time. Such bonds lack outstanding investment characteristics and in
fact may have speculative characteristics as well.

Ba: Bonds which are rated Ba are judged to have speculative elements; their
future cannot be considered as well-assured. Often the protection of interest
and principal payments may be very moderate, and thereby not well safeguarded
during other good and bad times over the future. Uncertainty of position
characterizes bonds in this class.

B: Bonds which are rated B generally lack characteristics of a desirable
investment. Assurance of interest and principal payments or of maintenance of
other terms of the contract over any long period of time may be small.

Caa: Bonds which are rated Caa are of poor standing. Such issues may be in
default or there may be present elements of danger with respect to principal or
interest.

Ca: Bonds which are rated Ca represent obligations which are speculative in high
degree. Such issues are often in default or have other marked shortcomings.

C: Bonds which are rated C are the lowest rated class of bonds, and issues so
rated can be regarded as having extremely poor prospects of ever attaining any
real investment standing.

Moody's applies numerical modifiers (1, 2 and 3) in each generic rating
classification from Aa through B in its corporate bond rating system. The
modifier 1 indicates that the security ranks in the higher end of its generic
rating category; modifier 2 indicates a mid-range ranking; and modifier 3
indicates that the issuer ranks in the lower end of its generic rating category.

Commercial Paper

Moody's Commercial Paper Ratings are opinions of the ability of issuers to repay
punctually promissory senior debt obligations not having an original maturity in
excess of one year. Issuers rated "Prime-1" or "P-1" indicate the highest
quality repayment ability of the rated issue.

                                       43

<PAGE>

The designation "Prime-2" or "P-2" indicates that the issuer has a strong
ability for repayment of senior short-term promissory obligations. Earnings
trends and coverage ratios, while sound, may be more subject to variation.
Capitalization characteristics, while still appropriate, may be more affected by
external conditions. Ample alternative liquidity is maintained.

The designation "Prime-3" or "P-3" indicates that the issuer has an acceptable
capacity for repayment of short-term promissory obligations. The effect of
industry characteristics and market compositions may be more pronounced.
Variability in earnings and profitability may result in changes in the level of
debt protection measurements and may require relatively high financial leverage.
Adequate alternate liquidity is maintained.

Issues rated "Not Prime" do not fall within any of the Prime rating categories.

Standard & Poor's  Rating Service ("S&P")
Debt Securities

AAA: Debt issues rated AAA are highest grade obligations. Capacity to pay
interest and repay principal is extremely strong.

AA: Debt issues rated AA have a very high degree of safety and very strong
capacity to pay interest and repay principal and differ from the highest rated
issues only in small degree.

A: Debt issues rated A are regarded as upper medium grade. They have a strong
degree of safety and capacity to pay interest and repay principal although it is
somewhat more susceptible in the long term to the adverse effects of changes in
circumstances and economic conditions than debt in higher rated categories.

BBB: Debt issues rated BBB are regarded as having a satisfactory degree of
safety and capacity to pay interest and re-pay principal. Whereas they normally
exhibit adequate protection parameters, adverse economic conditions or changing
circumstances are more likely to lead to a weakened capacity to pay interest and
re-pay principal for bonds in this category than for bonds in higher rated
categories.

BB, B, CCC, CC: Debt issues rated BB, B, CCC and CC are regarded on balance, as
predominantly speculative with respect to capacity to pay interest and pre-pay
principal in accordance with the terms of the bond. BB indicates the lowest
degree of speculation and CC the highest degree of speculation. While such bonds
will likely have some quality and protective characteristics, these are
outweighed by large uncertainties or major risk exposure to adverse conditions.

C: The rating C is reserved for income bonds on which no interest is being paid.

D: Debt issues rated D are in default, and payment of interest and/or repayment
of principal is in arrears.

NR: Indicates that no rating has been requested, that there is insufficient
information on which to base a rating or that S&P does not rate a particular
type of bond as a matter of policy.

Commercial Paper

S&P Commercial Paper ratings are current assessments of the likelihood of timely
payment of debts having an original maturity of no more than 365 days.

A-1: The A-1 designation indicates that the degree of safety regarding timely
payment is very strong.

A-2: Capacity for timely payment on issues with this designation is
satisfactory. However, the relative degree of safety is not as high as for
issues designated "A-1."

                                       44

<PAGE>

A-3: Issues carrying this designation have adequate capacity for timely payment.
They are, however, more vulnerable to the adverse effects of changes in
circumstances than obligations carrying the higher designations.

B: Issues rated "B" are regarded as having only a speculative capacity for
timely payment.

C: This rating is assigned to short-term debt obligations with a doubtful
capacity of payment.

D: Debt rated "D" is in payment default.

NR: Indicates that no rating has been requested, that there is insufficient
information on which to base a rating or that S&P does not rate a particular
type of bond as a matter of policy.

The ratings assigned by S&P may be modified by the addition of a plus (+) or
minus (-) sign to show relative standing within its major rating categories.

                 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, the Seligman Complex played a major
role in the geographical expansion and industrial development of the United
States.

SELIGMAN -- TIMES CHANGE...VALUES ENDURE

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

TIMES CHANGE...

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

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

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

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

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

TO THE SHAREHOLDERS

We are pleased to provide you with the October 31, 1998, Annual Report for
Seligman Henderson Global Fund Series, Inc., which includes the International
Fund, the Emerging Markets Growth Fund, the Global Growth Opportunities Fund,
the Global Smaller Companies Fund, and the Global Technology Fund. Troubled
markets around the world led to losses for all Seligman Henderson Global Funds
in the six months ended October 31. These losses caused several Funds to end the
fiscal year in negative territory.

While the 1998 fiscal year proved a difficult one for the Funds, the rebound
that started in October continued to gain steam in November and into December.
Some of the hardest hit asset classes this past summer -- technology and
small-company stocks -- recovered the most ground. In turn, the Global
Technology Fund and the Global Smaller Companies Fund, both in negative
territory as the fiscal year ended, posted substantial gains in recent weeks.
The International Fund and the Global Growth Opportunities Fund finished the
year with modest gains, despite losses in the second half of the fiscal year,
and have also posted gains since October. The Emerging Markets Growth Fund,
which had a significant loss for the year, continues to struggle along with
emerging markets in general.

Recent market activity indicates that the magnitude of the global financial
problems has been recognized and authorities are working to find solutions.
Several of the Asian markets first hit by turmoil last year have put stabilizing
policies in place; Japan has taken steps toward bank reform; the International
Monetary Fund, with the backing of the G7, has made a priority of avoiding a
destructive Brazilian devaluation; and interest rates have been lowered in the
US and around the world.

Looking ahead, the combination of lower valuations and positive fiscal action
have increased the attractiveness of stocks and bonds around the world. While
much still needs to be done globally to repair the damage -- especially in the
emerging markets of Asia, Brazil, and Russia -- we believe that significant
longer-term investment opportunities currently exist, and your investment
manager remains committed to the sound principles of long-term investing and
global diversification that have successfully stood the test of time.

Currently, virtually all companies are modifying their computer systems to
recognize dates of January 1, 2000, and beyond. This is often referred to as the
"Y2K" problem. Unless systems are updated, many applications may interpret the
last two digits of the year to mean 1900 instead of 2000. The Seligman
investment teams are well aware of the potential ramifications that the Year
2000 issue may have on companies whose securities are held in investment
portfolios. As part of each Team's investment process, members seek to identify
the preparedness of those firms whose underlying business models leave them
susceptible to Y2K problems. The evaluation of a company's Year 2000 readiness
has become an increasingly important factor which is considered by our
investment teams prior to investing in, disposing of, or continuing to hold, any
security.

In addition to monitoring the potential Y2K impact on our investments, we are
making sure our firm is in order. J. & W. Seligman & Co. Incorporated has
established a team to ensure that your investment and related services are not
disrupted. This team is supported by consulting firms specializing in Y2K
solutions. We are confident that when our plans are finalized and all systems
are tested, there will be no disruption in the services provided by your Fund.

Thank you for your continued support of Seligman Henderson Global Fund Series.
We look forward to serving your investment needs in the many years to come.

By order of the Board of Directors,

MARKET AND ECONOMIC OVERVIEW

OVERVIEW

The year ended October 31, 1998, was marked by volatility and a significant
divergence between the stock markets and economies of the East and the West. In
general, Western stock markets performed well for the year, before falling
sharply in mid-July. By contrast, most Asian stock markets fell throughout the
year before showing recent signs of a tentative recovery. The economic
background has been one of steadily deteriorating conditions as a financial
crisis initially limited to a few Asian countries spread throughout other
regions, culminating in the collapse of the Russian economy. Few countries were
left unscathed.


UNITED STATES

During the economic and market turmoil elsewhere, the US economy continued to
make good progress, although there has been some recent evidence of a slowing.
Corporate profits in the US initially held up well, but expectations declined
steadily throughout the year. For the third quarter of 1998, corporate profits
actually fell. Against this background, bond yields continued to hit new lows,
with the 30-year bond at one point yielding below 5%. The subsequent turmoil in
credit markets has been a major catalyst for the Federal Reserve's three
interest-rate cuts since September.


UNITED KINGDOM

The UK economy has recently begun to contract. The problems in the manufacturing
sector have now appeared in the consumer sector. Growth expectations for this
year and next have been significantly reduced, and corporate profits have come
under increasing pressure. More recently, the Monetary Policy Committee has cut
short-term interest rates, leading to a much needed decline in sterling. In this
negative environment, the UK market has generally underperformed other Western
markets.


CONTINENTAL EUROPE

In general, the performance of Continental European economies has been positive.
In particular, some of the peripheral economies have seen strong growth.
However, there are increasing signs that the problems in Asia are starting to
have a negative impact. Monetary policy has generally been on hold in the core
economies in advance of the introduction of the European Central Bank (ECB).
However, in the peripheral markets, interest rates are converging at the lower
levels of the core economies.

In the early part of 1998, European markets were booming. A favorable economic
background, positive earnings surprises, and abundant liquidity all helped to
generate strong returns. However, stock markets corrected sharply in July and
have since been slow to recover. As elsewhere, European growth expectations for
next year have been declining, but less so compared to other regions.


JAPAN

The economic background in Japan continued to deteriorate throughout the year.
The economy itself is clearly in recession. The government continues to announce
fiscal spending measures, thus far with little impact. During the year, the
financial crisis continued to worsen, with the government having to nationalize
one of the leading banks, although the authorities have promised to provide
enough cash to support the banking system. The Japanese market generally
declined over the period. Recently, however, it has shown signs of stabilizing.


PACIFIC REGION

The situation in the Pacific Region remained dreadful for most of the year, with
recessions in virtually all major economies. Lately, there have been signs that
conditions are at least not getting any worse, and the Chinese economy has
continued to move forward, helping to support the rest of the region.
Considerable problems still remain, but it may be that the worst is now behind
us. In recent months, stock markets have recovered quite strongly, particularly
in Thailand and South Korea. There have also been signs of stabilization in
currency markets.


EMERGING MARKETS (EX-PACIFIC)

In the early part of the year, both Latin America and emerging European markets
held up reasonably well, but as the depth of the Russian crisis became apparent,
most of these markets fell sharply. Growth everywhere is slowing down,
particularly in Latin America.


SUMMARY

Overall, world economic growth has slowed steadily throughout the year and
forecasts for next year suggest growth in the Organization for Economic
Cooperation and Development (OECD) is likely to be the weakest in many years.
This will negatively impact profits at a time when stock market valuations are
still high. It does appear that Western authorities have realized the
seriousness of the situation. There has been a significant lowering of interest
rates almost everywhere in the last three months. However, inflation continues
to decline virtually everywhere and the worry now is that lower inflation may
turn into deflation.

Cuts in interest rates should keep the world economy out of global recession
next year, but there remain considerable risks on the downside. Stock markets
have recovered from their worst position, but confidence remains fragile.
Provided the authorities stay vigilant, stock markets can make some progress
next year, but the route may be challenging. Please note, all stock market
returns quoted in the following Investment Reports are in US dollar terms.

INVESTMENT REPORT
SELIGMAN HENDERSON INTERNATIONAL FUND

PERFORMANCE REVIEW

The year ended October 31, 1998, was characterized by great volatility. In the
first half of the year, international equity markets went from strength to
strength, reaching record highs during the month of July. It then became evident
that the effects of the Asian economic crisis were finally beginning to be felt
around the world, and equities sold off on fears of a global crisis. However,
this setback did not last long, and stock markets around the globe rallied
sharply from their low point on October 5, 1998, as world leaders worked quickly
to avert the crisis and restore confidence by lowering interest rates.

Within this context, the Fund posted a 6.51% total return for the year based on
the net asset value of Class A shares, outpacing the 3.99% total return of its
peer group, as measured by the Lipper International Funds Average. The return of
the Fund's benchmark, the Morgan Stanley Capital International Europe,
Australasia, Far East (MSCI EAFE) Index, was 9.95% for the same period.


PORTFOLIO STRATEGY

UNITED KINGDOM

o  The UK followed the fortunes of the rest of world markets over the period,
   falling dramatically following July highs, but ending the Fund's fiscal year
   on a better note. As in other regions, banks were negatively impacted and
   concerns about exposure to emerging market debt arose over the sector as a
   whole. There has been a period of earnings downgrades and profit warnings
   across the board. Economic data reported in October added to the gloomy
   picture, indicating that the UK economy is slowing.

   THROUGHOUT THE YEAR, THE FUND MAINTAINED A BENCHMARK-NEUTRAL WEIGHTING IN THE
   UK AS WE VIEWED THE UK AS A DEFENSIVE ALTERNATIVE COMPARED TO THE REST OF THE
   WORLD. THIS MARKET HAS HELD UP RELATIVELY WELL, CONSIDERING THE TURMOIL AND
   VOLATILITY IN WORLD MARKETS. WHILE THE ECONOMY HAS RECENTLY BEGUN TO SLOW,
   THERE HAS BEEN A CUT IN INTEREST RATES, WITH FURTHER RATE CUTS EXPECTED. THIS
   FITS IN WITH THE PREDICTED "SOFT LANDING" SCENARIO, RATHER THAN A HARSH FALL
   INTO RECESSION.

CONTINENTAL EUROPE

o  In Continental Europe, markets have fallen from previous highs, but still
   ended the year up an impressive 27%. Economic growth for the region, though
   dented, should still prove the most resilient in the world. Although
   expectations for earnings have been revised lower, the many positive trends
   that have made Continental Europe an attractive equity environment are still
   intact and should produce strong gains over the next twelve months. European
   Monetary Union (EMU) will begin in January 1999 and will result in lower
   interest rates and low inflation. In addition, the pace of corporate
   restructuring should not slow as companies strive to boost profitability and
   shareholder returns.

THE FUND WAS OVERWEIGHTED IN THE CONTINENTAL EUROPEAN EQUITY MARKETS DURING THE
PAST YEAR. LOWER INTEREST RATES, CORPORATE RESTRUCTURING, THE ANTICIPATION OF

FUND OBJECTIVE

Seligman Henderson  International Fund, which commenced investment operations on
April 7, 1992, seeks long-term  capital  appreciation by investing  primarily in
the stocks of larger-sized companies outside the US.

                                       3

   EMU, AND STRONG FORECASTED EARNINGS GROWTH HELPED TO LIFT STOCK PRICES HIGHER
   IN THE FIRST HALF OF 1998, OUTPERFORMING MOST OTHER REGIONAL MARKETS.
   DESPITE THE RECENT GLOBAL EQUITY MARKET CORRECTION, THE FUND WILL LIKELY
   MAINTAIN ITS REGIONAL OVERWEIGHTING AS WE ANTICIPATE FURTHER STRONG GAINS IN
   TELECOMMUNICATIONS, FINANCIALS (ESPECIALLY INSURERS),  UTILITIES, AND
   RETAILING.

JAPAN

o  The Japanese market finished the year down 14.3% in US dollar terms, due
   mainly to fears about the economy and the ailing banking system. Economic
   data provided supporting evidence that the economy is in fact in a period of
   recession. Following the resignation of Prime Minister Hashimoto in July,
   there was a period of optimism that the new premier, Mr. Obuchi, would
   implement the necessary changes to stimulate the economy and to restructure
   the ailing financial system. However, this enthusiasm proved short lived as
   the government has failed thus far to deliver any positive policy changes.

   THE FUND MAINTAINED A LOW WEIGHTING IN JAPAN THROUGHOUT THE YEAR AS WE DID
   NOT ANTICIPATE ANY ECONOMIC RECOVERY IN THE NEAR TERM. WE DO NOT EXPECT A
   SPEEDY SOLUTION TO THE BANKING CRISIS NOR SUFFICIENT FISCAL STIMULUS TO BOOST
   THE ECONOMY, AND BELIEVE THAT SIGNIFICANT RISKS FOR THE JAPANESE STOCK MARKET
   REMAIN. UNTIL CLEARER EVIDENCE THAT THE CONDITION OF THE JAPANESE ECONOMY IS
   IMPROVING, WE WILL REMAIN CAUTIOUS.

PACIFIC

o  The Pacific Basin ended the year down, with markets across the region
   declining 13.7% on average. However, the region had a reversal of fortunes in
   the last few months due to the Hong Kong government's decision to intervene
   in its stock market, which had the effect of artificially inflating prices.
   Other countries such as Malaysia and Indonesia have continued to underperform
   dramatically and remain extremely unstable. The protectionism that started in
   Malaysia threatens the region with potential isolation. The continuing
   recession in Japan is also preventing the region from exporting its way out
   of trouble.

   SINCE JUNE 1997, THE FUND HAS BEEN SIGNIFICANTLY UNDERWEIGHT IN THE PACIFIC
   REGION. THE ECONOMIC CRISIS EXACERBATED THE PRESSURES TO DEVALUE CURRENCIES
   THROUGHOUT THE REGION, ULTIMATELY HAVING AN IMPACT ON THE EQUITY MARKETS OF
   DEVELOPED COUNTRIES BEGINNING IN JULY 1997. WITH LESS RISKY INVESTMENT
   OPPORTUNITIES AVAILABLE IN RELATIVELY MORE STABLE AREAS OF THE WORLD, WE
   MAINTAINED A MINIMAL EXPOSURE LEVEL TO PACIFIC MARKETS THROUGHOUT THE PAST
   YEAR, AND EXPECT TO REMAIN UNDERWEIGHT IN THE NEAR TERM.

EMERGING MARKETS

o  Emerging markets suffered badly from a background of sliding commodity prices
   and slowing global economic growth. In addition, Russia's devaluation and
   credit default have weighed heavily on investor sentiment. Elsewhere, there
   was a loss of confidence in the Brazilian government's ability to solve its
   fiscal problems. This led to capital outflows and fear of devaluation. Our
   view is that the international assistance package for Brazil should begin to
   restore investor confidence, allowing for a recovery. We have, therefore,
   decided to maintain a modest exposure to the most established companies in
   selected emerging markets where valuations are attractive and at historic
   lows.

   DURING THE COURSE OF THE YEAR, THE FUND'S HOLDINGS IN EMERGING MARKETS
   TYPICALLY RANGED BETWEEN 5% AND 10% OF TOTAL ASSETS. THE FUND'S EXPOSURE WAS
   PRIMARILY IN EASTERN/CENTRAL EUROPEAN AND LATIN AMERICAN COUNTRIES.
   INVESTMENTS IN EMERGING MARKETS WERE FOCUSED ON HIGHER-QUALITY, MORE LIQUID
   NAMES, RATHER THAN LESS LIQUID SMALLER-CAP ISSUES AND INVESTMENTS IN THE
   "FRONTIER"COUNTRY MARKETS.

OUTLOOK

The outlook for global stock markets continues to be positive as interest-rate
reductions and efforts to prevent any further spreading of the financial crises
to Latin America have boosted investor sentiment. But despite these
improvements, risks remain and markets must anticipate slower economic and
corporate profit growth. Within this context, we expect that Continental Europe,
the UK, and select emerging markets may offer attractive return potential, as we
believe that corporate earnings growth has the potential to be greatest in these
regions. While we expect the economies of Japan and the Pacific region to remain
depressed over the next few months, we believe both regions could improve
significantly over the longer term.

than or less than the performance shown for Class A shares, based on the

INVESTMENT REPORT
Seligman Henderson Emerging Markets Growth Fund

PERFORMANCE REVIEW

Emerging markets suffered from the effects of a series of currency crises and
associated global contagion. Over the year as a whole, the Fund had a total
return of -29.43% based on the net asset value of Class A shares. This compares
to a -30.98% total return posted by the Morgan Stanley Capital International
Emerging Markets Free Index and to the -31.48% total return posted by the Lipper
Emerging Markets Funds Average.

Fund management was more challenging than usual. The strategy consisted of
trying to avoid investments in markets with weak currencies, while increasing
cash levels during periods of global uncertainty, particularly in November -
December 1997, and August - September 1998. High levels of cash held during the
attack on the Brazilian real were reinvested in the markets in October after
confidence was, to some extent, restored through US interest-rate cuts, the
strengthening of the yen, and supportive statements from the leadership of the
G7 group of industrialized countries.


PORTFOLIO STRATEGY

In regional terms, there were a number of significant trends. The Fund's
overweight position in Emerging Europe was maintained throughout the year,
although exposure to Russia was greatly reduced. Exposure to Far Eastern markets
was increased over the year, but exposure to Latin America was reduced largely
due to economic uncertainty in Brazil.


PACIFIC REGION

o  The devaluation of the Thai baht in July 1997 greatly affected the markets of
   the South Pacific region (Thailand, the Philippines, Malaysia, and
   Indonesia). Sentiment in the markets remained weak during the latter months
   of 1997 as currency instability moved to North Pacific markets. The
   Indonesian currency came under attack in January 1998. There was a brief
   rally in currencies and markets in the first quarter of 1998, but the
   Malaysian government was forced to introduce currency controls in September.
   Other than in the Malaysian ringit, there was a rally in currencies toward
   the end of the Fund's year. Market performances ranged between a fall of 8.7%
   in the Philippine index to a fall of 76.8% in the Indonesian index.

   THE FUND RETAINED HOLDINGS IN THAILAND AND THE PHILIPPINES THROUGHOUT THE
   PERIOD. A SMALL NUMBER OF HOLDINGS WERE HELD IN MALAYSIA DURING THE FIRST
   QUARTER OF THE YEAR BUT THESE WERE SOLD BEFORE THE IMPOSITION OF CURRENCY
   CONTROLS. TOWARD THE END OF THE FUND'S YEAR, THE FUND ESTABLISHED HOLDINGS IN
   Thai Farmers Bank AND Bangkok Bank AS THE OUTLOOK FOR THAILAND IMPROVED.

o  In the North Pacific region, the direction of the markets was dictated by
   currency moves. The attack on the Hong Kong dollar in November 1997 was
   followed by the South Korean currency crisis later in December. The Taiwanese
   market, following the effective floating of the currency in October, remained
   relatively untouched by the crisis. The Taiwanese index fell 14.9%, the South
   Korean index fell 24.5%, and the China (non-domestic) index fell 52.8%.

   THE FUND HELD FEW POSITIONS IN THE REGION UNTIL SEPTEMBER, WHEN THERE WERE
   SIGNIFICANT ADDITIONS TO THE PORTFOLIO. IN CHINA, THE PORTFOLIO REMAINS
   FOCUSED ON INFRASTRUCTURE. WE HAVE PURCHASED China Telecom, Cheung Kong
   Infrastructure, AND China Resources Enterprise. IN SOUTH KOREA, WE SOLD OUR
   HOLDING IN Samsung Electronics AND PURCHASED SK Telecom Group AND Korea
   Electric Power. IN TAIWAN, OUR HOLDINGS REMAINED FOCUSED ON BROADLY BASED
   CLOSED-END FUNDS.

INVESTMENT REPORT
Seligman Henderson Emerging Markets Growth Fund

LATIN AMERICA

o  Latin American markets remained volatile with attacks on the Brazilian real
   in November - December 1997, and September 1998. However, both the Brazilian
   real and Argentine peso were successfully defended. The region's markets
   rebounded after the mid-September promise of G7 and IMF support for the
   defense of the real. Throughout the year, the Mexican currency also suffered
   periods of instability, and domestic interest rates were put up in its
   defense. The performances for the indices of the major markets were as
   follows: Argentina fell 12.1%, Mexico fell 21.0%, and Brazil fell 34.1%.

   OUR CORE EXPOSURE IN LATIN AMERICA REMAINS MEXICO, WHERE THE DEFENSIVELY
   POSITIONED HOLDINGS FOCUS ON BREWERIES (Femsa), BOTTLERS (Pepsi-Gemex AND
   Panamerican Beverages), AND TELECOMMUNICATIONS (Telemex AND Grupo Iusacell).
   HOLDINGS IN BRAZIL AND ARGENTINA WERE ADJUSTED FOR THE OUTLOOK FOR THEIR
   CURRENCIES. IN PARTICULAR, WE SOLD BRAZILIAN COMPANIES WITH US DOLLAR
   EXPOSURE SUCH AS CEMIG AND Sabesp. HOWEVER, WE RETAINED OUR CORE HOLDINGS OF
   Telebras AND Petrobras.

EMERGING EUROPE

o  The Emerging European region produced significantly diverse performances,
   largely dependent on the currency and interest-rate events for the year.
   Greece, which joined the European monetary system during the year in
   preparation to joining European Monetary Union (EMU), benefited from currency
   stability and falling interest rates. The Greek market rose 33.8%. Portugal,
   which joins EMU on January 1, 1999, experienced similar beneficial effects,
   rising 35.4%.

   By contrast, the Russian market was hit by a severe internal budget deficit
   which led to the collapse of the rouble and the replacement of a reformist
   government with a government led by former communists. The Russian index fell
   by 85.2%. The overall negative sentiment toward emerging markets caused other
   emerging European markets to suffer in varying degrees. Hungary fell 7.5%,
   the Czech Republic fell 10.2%, and Poland fell 16.2%. Turkey, affected by
   high interest rates and political uncertainty, fell 50.7%.

   THE KEY PORTFOLIO MOVE IN THE REGION WAS AN INCREASE TO THE GREEK WEIGHTING
   THROUGH THE PURCHASE OF Alpha Credit Bank, Hellenic Telecommunication (OTE),
   AND Sarantis. MOST HOLDINGS IN RUSSIA WERE SOLD FOLLOWING THE MARKED
   DETERIORATION OF THE ECONOMIC AND POLITICAL OUTLOOK AND THE REMAINDER WERE
   SOLD AFTER THE FUND'S YEAR END. ALL HOLDINGS IN PORTUGAL WILL BE SOLD BEFORE
   THE COUNTRY JOINS EMU. OF NOTE DURING THE YEAR WAS THE INCREASED WEIGHTING OF
   THE FUND INTO BOTH POLAND AND HUNGARY WITH THE PURCHASE OF Elektrim, Matav,
   Powszechny Bank, AND Prokom Software, AND THE RE-ENTRY INTO THE CZECH
   REPUBLIC WITH THE PURCHASE OF Ceske Radiokomunikace.

OTHER MARKETS

o  Other markets in which the Fund has been invested were affected by the
   general pressures on emerging markets. The Indian market fell 34.2% and the
   South African market fell 25.4%. Within the markets of the Middle East and
   North Africa, the Israeli (domestic) index fell 18.7% and the Egyptian index
   fell 37.4%.

   WE MAINTAINED LOW WEIGHTINGS IN INDIA DURING THE PERIOD, FOCUSING ON THE
   SECULAR GROWTH STOCKS OF Mahangar Telephone Nigam (THE BOMBAY AND DELHI
   TELEPHONE SYSTEM) AND THE Indian Tobacco Company (ITC). THE SOUTH AFRICAN
   WEIGHTING WAS REDUCED BEFORE THE WEAKNESS IN SEPTEMBER BUT INCREASED IN
   OCTOBER WHEN INTEREST RATES BEGAN TO EASE, WITH PURCHASES OF Nedcor (A BANK)
   AND Pepkor (A RETAILER). OUR ISRAELI EXPOSURE WAS SWITCHED FROM TECHNOLOGY
   SECTOR HOLDINGS TO Bank Hapoalim AND Blue Square (A SUPERMARKET). WITHIN THE
   EGYPTIAN PORTFOLIO, WE ADDED Al-ahram Beverages (A BREWERY AND BOTTLING
   COMPANY).

OUTLOOK

Following the supportive statements of the leaders of the G7 and recent policy
actions of the US and Japan on various issues, the outlook for emerging markets
is more optimistic. Moreover, there are positive developments in each of the
major regions within the Pacific, with trade surpluses likely to boost liquidity
in domestic markets and provide some stability to the currencies. In Emerging
Europe, convergence and integration is likely to continue to positively affect
Greek and Central European markets. Although economic growth will be lackluster,
Latin America is likely to benefit from lower real interest rates. Overall, the
emerging markets are likely to show some recovery in the year ahead; although
market performance will differ widely and progress is likely to be volatile.

   Performance data quoted represent changes in prices and assume that all
distributions within the periods are invested in additional shares. The rates of
return will vary and the principal value of an investment will fluctuate.
Shares, if redeemed, may be worth more or less than their original cost.



- -----------------
  * Returns for periods of less than one year are not annualized.
 ** Return figures reflect any change in price and assume the investment of
    dividends and capital gain distributions. Returns for Class A shares are
    calculated with and without the effect of the initial 4.75% maximum sales
    charge. Returns for Class B shares are calculated with and without the
    effect of the maximum 5% contingent deferred sales charge ("CDSC"), charged
    on redemptions made within one year of the date of purchase, declining to 1%
    in the sixth year and 0% thereafter. Returns for Class D shares are

PERFORMANCE AND PORTFOLIO OVERVIEW
Seligman Henderson Emerging Markets Growth Fund

   This chart compares a $10,000 hypothetical investment made in Seligman
Henderson Emerging Markets Growth Fund, with and without the initial 4.75%
maximum sales charge for Class A shares, with the 3% contingent deferred sales
charge ("CDSC") for Class B shares, and without the 1% CDSC for Class D shares,
and assumes that all distributions within the period are invested in additional
shares, since the commencement of operations on May 28, 1996, through October
31, 1998, to a $10,000 hypothetical investment made in the Lipper Emerging
Markets Funds Average and the Morgan Stanley Capital International Emerging
Markets Free Index (MSCI EMF Index) for the same period. It is important to keep
in mind that indices and averages exclude the effect of fees and/or sales
charges.

INVESTMENT REPORT
Seligman Henderson Global Growth Opportunities Fund


PERFORMANCE REVIEW

For the twelve months ended October 31, 1998, Seligman Henderson Global Growth
Opportunities Fund posted a total return of 9.52% based on the net asset value
of Class A shares, compared to the 5.31% total return of its peers, as measured
by the Lipper Global Funds Average. Stocks around the world, as measured by the
Morgan Stanley Capital International World Index (MSCI World Index), posted a
total return of 15.69% for the same period.

The past calendar year was characterized by several distinct phases of global
market activity. From mid-January to mid-July, world markets rose strongly by
approximately 25%, led by Continental Europe and fueled by expectations of lower
inflation and interest rates. After mid-July, the combination of Russian debt
default, speculative attacks against emerging market currencies, and a
worse-than-expected economic impact from Asia upon the rest of the world led to
sharp market corrections. During October, in response to the deflationary
threats facing global economic activity, interest rates were cut in many parts
of the world and a coordinated program of support for the world's financial
system was implemented. As a result, many markets recovered confidence.

FUND OBJECTIVE

Seligman Henderson Global Growth Opportunities Fund, which commenced operations
on November 1, 1995, seeks long-term capital appreciation by investing primarily
in the stocks of companies that have the potential to benefit from global
economic or social trends.

During the year, the Fund's bias for stocks with higher earnings growth and a
preference for Continental Europe proved to be the major positive factors. In
contrast, the investments in Asia and other emerging markets negatively impacted
performance. However, the exposure to these markets was reduced significantly
through the year.


PORTFOLIO STRATEGY

The Fund remained broadly invested in the four major growth themes : QUALITY OF
LIFE (36%), PRODUCTIVITY (23%), CONSUMPTION (24%) and GLOBAL TRADE (12%). During
the year, we reduced exposure to the Productivity theme -- in particular, by
reducing investments in Asian technology stocks -- and at the same time we
increased investment in the more stable Quality of Life theme with its emphasis
on health care stocks. Within each theme, we shifted the Fund's investments
toward those with greater earnings reliability.

QUALITY OF LIFE

o As earnings growth became more uncertain around the world, we added to the
  Quality of Life sub-themes of health care and savings. During the recent
  market turmoil, a "flight to quality" benefited the stocks in this theme.

   DURING THE PAST YEAR, WE ADDED SEVERAL DRUG STOCKS, NAMELY Lilly (Eli) IN THE
   US, SmithKline Beecham IN THE UK, AND Astra IN SWEDEN. WHILE THE GLOBAL DRUG
   STOCKS' VALUATIONS REFLECT THEIR BETTER GROWTH PROSPECTS, WE THINK THEY WILL
   PROVIDE GREATER EARNINGS SAFETY IN VOLATILE TIMES. IN ADDITION, WITH RISING
   INFLOWS INTO MUTUAL FUNDS IN EUROPE, WE ADDED Skandia IN SWEDEN AND Helvetia
   Patria IN SWITZERLAND, BOTH BENEFICIARIES OF THE RISING DEMAND FOR SAVINGS
   PRODUCTS AND FALLING INTEREST RATES.

PRODUCTIVITY

o The deterioration in economic activity, first in Asia and then around the
  world, reduced the prospects for many technology stocks. In particular,
  semiconductor and PC businesses faced a difficult environment. In response, we
  reduced the Fund's exposure to technology stocks.

   SOUTHEAST ASIA'S FINANCIAL CRISIS, WHICH BEGAN LAST YEAR, SIGNIFICANTLY
   REDUCED THE OUTLAYS FOR CAPITAL EXPENDITURE, INCLUDING TECHNOLOGY UPGRADES.
   AS A RESULT, WE SOLD ALMOST ALL OF OUR RELATED INVESTMENTS IN THAT REGION,
   INCLUDING Silicon Precisionware, Advanced Systems, Hotung, Synnex, Electronic
   Resources, AND Datacraft. IN EUROPE, WHERE THE PREPARATION FOR EUROPEAN
   MONETARY UNION AND THE NEW MILLENNIUM PUSHED UP THE DEMAND FOR SOFTWARE AND
   REGIONAL COMMUNICATION, WE ADDED Cap Gemini, EUROPE'S LARGEST SOFTWARE HOUSE,
   AND Equant, A PROVIDER OF DATA NETWORKS TO MULTINATIONAL BUSINESSES.

CONSUMPTION

o Although the aggregate exposure to the Consumption theme hardly changed during
  the year, there was a significant shift in exposure from Asia and Emerging
  Markets toward Europe. The economic malaise in Asia has severely dented
  consumer confidence, while in Europe, rising employment and falling interest
  rates had the opposite effect.

   WE SOLD A NUMBER OF STOCKS IN JAPAN, HONG KONG, AND SINGAPORE, ALL RELATED TO
   CONSUMPTION. AT THE SAME TIME, WE INVESTED IN TWO RETAILERS IN SPAIN WHERE
   CONSUMPTION GROWTH HAS BEEN EXCEPTIONALLY STRONG: Centros Comerciales
   CONTINENTE, WHICH OPERATES A NATIONWIDE CHAIN OF SUPERMARKETS, AND
   Superdiplo, WHICH ALSO OPERATES SUPERMARKETS, BUT MAINLY IN THE SPANISH
   ISLANDS. IN THE SAME TREND, WE ADDED ANOTHER SUPERMARKET CHAIN, Kroger, IN
   THE US.

GLOBAL TRADE

o The major emphasis is in the telecommunications sub-theme. This sector has
  performed well in the past year, with many companies providing either
  stability or growth in earnings fueled by more communication traffic and/or
  cost-cutting.

   OF NOTE, WE ADDED Matav IN HUNGARY AND Hellenic Telecommunication
   Organization IN GREECE. BOTH SHOULD BENEFIT FROM AN EXPANSION IN THEIR
   NETWORKS AND THE APPLICATION OF NEW TECHNOLOGY TO OFFER VALUE-ADDED SERVICES.

OUTLOOK

World stock markets have been reflecting the global economy's synchronization
toward slower growth. At times like these, profit growth becomes more scarce and
uncertain. Such concern has raised market volatility everywhere. However, we
believe a global economic recession accompanied by prolonged deflation is
unlikely, since appropriate action by the major central banks would be a remedy.
Therefore, excessive pessimism does not seem warranted either. In our opinion,
the current cyclical downturn in economic activity and corporate profitability
around the world should dissipate as we approach the end of the millennium.

The world has an excess of industrial capacity. Until demand rises sufficiently
to meet it, pricing power will be scarce in industrial goods markets. Businesses
in the service sectors are likely to fare better in such an environment.
Fortunately, the Fund's investments are largely in these sectors.

Also, during times of subdued profit advance, high quality growth stocks tend to
perform well. When there is much near-term uncertainty, it is appropriate to
look at the secular trends which are most likely to powerfully drive wealth
creation. In accordance with this philosophy, we will continue to use a thematic
approach to identify superior growth opportunities in which to invest.

   Performance data quoted represent changes in prices and assume that all
distributions within the periods are invested in additional shares. The rates of
return will vary and the principal value of an investment will fluctuate.
Shares, if redeemed, may be worth more or less than their original cost.


- --------------------------------------------------------------------------------
   * Returns for periods of less than one year are not annualized.

  ** Return figures reflect any change in price and assume the investment of
     dividends and capital gain distributions. Returns for Class A shares are
     calculated with and without the effect of the initial 4.75% maximum sales
     charge. Returns for Class B shares are calculated with and without the
     effect of the maximum 5% contingent deferred sales charge ("CDSC"), charged
     on redemptions made within one year of the date of purchase, declining to
     1% in the sixth year and 0% thereafter. Returns for Class D shares are
     calculated with and without the effect of the 1% CDSC, charged on
     redemptions made within one year of the date of purchase.

 *** The Lipper Global Funds Average and the Morgan Stanley Capital
     International World Index (MSCI World Index) are unmanaged benchmarks that
     assume reinvestment of dividends. The Lipper Global Funds Average excludes
     the effect of sales charges and the MSCIWorld Index excludes the effect of
     fees and sales charges. The monthly performance of the Lipper Global Funds
     Average is used in the Performance and Portfolio Overview. Investors cannot
     invest directly in an average or an index.

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

  ++ From April 30, 1996.

   0 From October 31, 1995.

PERFORMANCE AND PORTFOLIO OVERVIEW
Seligman Henderson Global Growth Opportunities Fund

   This chart compares a $10,000 hypothetical investment made in Seligman
Henderson Global Growth Opportunities Fund, with and without the initial 4.75%
maximum sales charge for Class A shares, and without the 1% contingent deferred
sales charge ("CDSC") for Class D shares, and assumes that all distributions
within the period are invested in additional shares, since the commencement of
investment operations on November 1, 1995, through October 31, 1998, to a
$10,000 hypothetical investment made in the Lipper Global Funds Average and the
Morgan Stanley Capital International World Index (MSCIWorld Index) for the same
period. It is important to keep in mind that indices and averages exclude the
effect of fees and/or sales charges.

   There are specific risks associated with global investing, such as currency
fluctuations, foreign taxation, differences in financial reporting practices,
and rapid changes in political and economic conditions.

   As shown on page 26, the performance of Class B shares will be greater than
or less than the performances shown for Class A shares and Class D shares, based
on the differences in sales charges and fees paid by shareholders. Past
performance is not indicative of future investment results.

INVESTMENT REPORT
Seligman Henderson Global Smaller Companies Fund

PERFORMANCE REVIEW

For the 12 months ended October 31, 1998, Seligman Henderson Global Smaller
Companies Fund declined 5.82% based on net asset value of Class A shares. In the
same period, the Fund's peer group, as measured by the Lipper Global Small Cap
Funds Average, fell 10.59%, and the Salomon Smith Barney Extended Market Index
World fell 4.49%.

The performance of world markets during the period under review was sharply
divided -- while markets in the Far East were falling, Western markets were
scaling new heights. July saw the peak in these markets, before concerns about
the impact of Asian economic weakness began to gather pace. The growing sense of
crisis swept emerging markets, leading to a devaluation of the Russian rouble,
and fears that Brazil would be forced to devalue. Equity markets collapsed as
concerns about a global financial meltdown spread. As investors became more risk
averse, government bond markets rose to new highs. The rescue of a US hedge fund
and the subsequent reduction in interest rates in the US marked the turning
point for equities, as investors became more confident that the global financial
crisis would be averted. The last two weeks of October saw markets rally
strongly.


FUND OBJECTIVE

Seligman Henderson Global Smaller Companies Fund, which commenced investment
operations on September 9, 1992, seeks long-term capital appreciation by
investing in smaller-company stocks in the US and around the world.

PORTFOLIO STRATEGY
UNITED STATES

o  For much of the period, smaller companies in the US were disappointing,
   lagging both their larger counterparts and smaller companies in other regions
   of the world. Smaller companies in the US peaked in April, then declined
   gradually until the summer, when they took a lurch downward. Their
   underperformance in the first phase came as investors concentrated on a few
   large-cap names and drove the index higher. The poor performance of small
   caps in the summer can be attributed to risk aversion, as investors fled to
   the safety of bonds or cash from the perceived risk of smaller companies.
   However, in October, smaller companies began to stage a recovery, rallying by
   almost 22%, as measured by the Salomon Smith Barney Extended Market Index
   World. Nevertheless, for the year as a whole, smaller companies fell almost
   13%.

   EXPOSURE TO THE US ROSE MARGINALLY FROM THE BEGINNING OF THE YEAR. LOOKING
   FORWARD, WE WILL LIKELY INCREASE THE ALLOCATION TO THE US TO 50%. FOLLOWING
   THEIR CORRECTION, US SMALL CAPS ARE BEGINNING TO ATTRACT INVESTOR ATTENTION,
   AS THEY OFFER AN ATTRACTIVE COMBINATION OF GROWTH AT REASONABLE VALUATIONS.

UNITED KINGDOM

o  In the UK, smaller companies fared poorly over the year to October, rising
   only 3.2%, compared to a rise of 16.3% in larger companies. These figures,
   however, ignore a strong outperforming period in the second quarter of 1998.
   Following this period, smaller companies fell in line with other markets.

INVESTMENT REPORT
Seligman Henderson Global Smaller Companies Fund

   THE UK ECONOMY IS SLOWING AND INTEREST RATES REMAIN HIGH -- NOT AN IDEAL
   ENVIRONMENT FOR SMALLER COMPANIES. HOWEVER, THE FUND CONTINUES TO EMPHASIZE
   COMPANIES IN THE SERVICE SECTOR WHICH HAVE VISIBLE EARNINGS GROWTH AND
   PRICING POWER. THE ALLOCATION TO THE UK WAS OVERWEIGHT THROUGHOUT THE PERIOD,
   VARYING BETWEEN 19% AND 25%.

   THE ALLOCATION TO THE UK WILL LIKELY BE REDUCED OVER THE COMING MONTHS. WHILE
   THE OVERWEIGHT POSITION HAS BEEN POSITIVE FOR PERFORMANCE, CONCERN ABOUT THE
   ECONOMIC OUTLOOK AND THE SPEED OF INTEREST-RATE CUTS MAY LEAVE SMALLER
   UK-BASED COMPANIES ON THE SIDELINES FOR SOME TIME.

CONTINENTAL EUROPE

o  Continental Europe was the best-performing region for smaller companies over
   the last 12 months. Total returns were 16.2% compared with 25.9% for larger
   companies. The stock markets of Italy and Spain offered the best returns at
   48.35% and 35.2%, respectively. Overall, the strong growth in the European
   economy, lower interest rates, low valuations, and reasonable earnings growth
   rates offered many attractive investment opportunities.

   The portfolio has maintained a neutral to slightly overweight position in
   Continental Europe throughout the period, peaking at approximately 25% in
   November 1997 and ending the period at approximately 23%. Toward the end of
   the period, concern has grown about the future growth prospects for Europe.
   The Fund has been reducing exposure to more cyclical sectors of the market,
   but will maintain a neutral weighting for the next few months.

JAPAN

o  For much of the year, the economic background in Japan continued to
   deteriorate. The market appeared to be in the grip of deflation, a banking
   crisis, and policy paralysis. The government announced fiscal stimulus
   packages which failed to meet investor expectations, and the market fell.
   Indeed, for the period as a whole, smaller companies fell 17.5%, compared to
   a fall of 15% for larger companies. A change in government during the summer
   did little to improve investor sentiment, and plans for a resolution of the
   banking crisis were met with skepticism among investors. Indeed, concern
   about the impact of Japan's problems on the rest of the world was a partial
   trigger for the collapse in world markets in the summer.

   THE FUND HAD BEEN SIGNIFICANTLY UNDERWEIGHTED IN JAPANESE SMALLER COMPANIES
   THROUGHOUT THE PERIOD. HOWEVER, THE ALLOCATION WAS INCREASED TOWARD THE END
   OF THE YEAR, AS TENTATIVE SIGNS OF SOME IMPROVEMENT IN THE JAPANESE SITUATION
   EMERGED. THE MOVE TO GRADUALLY INCREASE THE POSITION CLOSER TO THE FUND'S
   BENCHMARK WILL LIKELY CONTINUE OVER THE NEXT FEW MONTHS.

PACIFIC BASIN

o  Given the economic background, it was not surprising that the Pacific Basin
   was the worst performer for the 12-month period ending on October 31, falling
   27.6%. There was no respite to the worsening news in the region, although
   during the drop in global markets in August and particularly in September,
   the Pacific Basin performed relatively well. As US interest rates and the
   dollar fell, interest rates in the region also declined, providing a stimulus
   to equity markets.

   The Fund began the year with an underweighted position which remained in
   place throughout the period. Looking ahead, we are likely to increase the
   allocation. While the underperformance from smaller companies has been
   severe, there are tentative signs of improvements at the corporate level
   which may lead to selective opportunities in the region.

SUMMARY

The past year has seen a fundamental change in most equity markets. All-time
highs were followed by sharp corrections, which were then followed by sharp
rallies. As volatility increased, investors avoided the perceived risks of
smaller companies. As a result, smaller companies, as measured by the Salomon
Smith Barney Extended Market Index World, underperformed large companies by
20.2% for the year.

Clearly, continued volatility will not favor small caps. However, there are
signs of renewed investor interest in US small caps which could spread to other
regions. Certainly the growth and valuation combination of small caps looks more
attractive than those for large caps in the US, Europe, and the UK, while there
is plenty of scope for positive surprise in Asia.

   Performance data quoted represent changes in prices and assume that all
distributions within the periods are invested in additional shares. The rates of
return will vary and the principal value of an investment will fluctuate.
Shares, if redeemed, may be worth more or less than their original cost.


- ------------------------
*    Returns for periods of less than one year are not annualized.
**   Return figures reflect any change in price and assume the investment of
     dividends and capital gain distributions. Returns for Class A shares are
     calculated with and without the effect of the initial 4.75% maximum sales
     charge. Returns for Class B shares are calculated with and without the
     effect of the maximum 5% contingent deferred sales charge ("CDSC"), charged
     on redemptions made within one year of the date of purchase, declining to
     1% in the sixth year and 0% thereafter. Returns for Class D shares are
     calculated with and without the effect of the 1% CDSC, charged on
     redemptions made within one year of the date of purchase.

SELIGMAN HENDERSON GLOBAL SMALLER COMPANIES FUND

   This chart compares a $10,000 hypothetical investment made in Seligman
Henderson Global Smaller Companies Fund Class A shares, with and without the
initial 4.75% maximum sales charge, and assumes that all distributions are
invested in additional shares, since the commencement of investment operations
on September 9, 1992, through October 31, 1998, to a $10,000 hypothetical
investment made in the Lipper Global Small Cap Funds Average and the Salomon
Smith Barney Extended Market Index World (Salomon Smith Barney EM Index World)
for the same period. It is important to keep in mind that indices and averages
exclude the effect of fees and/or sales charges.

   There are specific risks associated with global investing, such as currency
fluctuations, foreign taxation, differences in financial reporting practices,
and rapid changes in political and economic conditions.

   As shown on page 36, the performances of Class B and D shares will be greater
than or less than the performance shown for Class A shares, based on the
differences in sales charges and fees paid by shareholders. Past performance is
not indicative of future investment results.

INVESTMENT REPORT
Seligman Henderson Global Technology Fund


PERFORMANCE REVIEW
Seligman Henderson Global Technology Fund posted a return of -0.79% based on the
net asset value of Class A shares for the year ended October 31, 1998. This
compares to the 5.31% and 11.10% total returns of its peers, as measured by the
Lipper Global Funds Average and the Lipper Science and Technology Funds Average,
respectively. The Morgan Stanley Capital International World Index posted a
total return of 15.69% for the same period.

The caution that we expressed in our report of April 30, 1998, proved
appropriate, although our forecast did not extend to anticipating the scale of
the collapse in technology share prices from August through October. Without the
sharp rebound that we enjoyed over the last three weeks of October, we would
have been obliged to report on one of the most disappointing half years since
the Fund's launch.


US technology shares fared least poorly over the period although, at one stage,
the Pacific Stock Exchange Technology Index had fallen more than 25% from its
late July high. Smaller companies in the sector declined throughout the summer,
and by early October, had fallen more than 40% from their April peak. In
contrast, European technology shares proved resilient for most of the period
before collapsing in September. Meanwhile, Asian technology companies continued
their long period of underperformance.

FUND OBJECTIVE
Seligman Henderson Global Technology Fund, which commenced operations on May 23,
1994, seeks long-term capital appreciation by investing in securities of
companies around the world that operate in the technology and technology-related
industries.

PORTFOLIO STRATEGY
    WE RAISED SUBSTANTIAL LIQUIDITY DURING THE SUMMER, TAKING PROFITS IN A BROAD
RANGE OF EUROPEAN STOCKS. A SIGNIFICANT PROPORTION OF THAT LIQUIDITY WAS LATER
REINVESTED IN THE US, ESPECIALLY JUST AFTER THE END OF THE FUND'S OCTOBER FISCAL
YEAR.


    WE BELIEVE THAT THE EARLY OCTOBER LOW FOR THE SECTOR HAD ALL THE
CHARACTERISTICS OF A MAJOR BOTTOM -- ONE WHICH SEEMs LIKELY, AT LEAST IN THE
SHORT TERM, TO BE MARKED BY AN END TO THE EXTRAORDINARY UNDERPERFORMANCE OF
SMALL-CAP US TECHNOLOGY SHARES. WE THEREFORE ADDED TO OUR POSITIONS IN A NUMBER
OF SMALL- AND MID-CAP COMPANIES SUCH AS Amkor Technology, DII Group, AND
Ziff-Davis. WE HAVE ALSO ADDED TO OUR CYCLICAL TECHNOLOGY WEIGHTING IN THE US.
THIS REFLECTS OUR BELIEF THAT CONDITIONS IN THE SEMICONDUCTOR MARKET ARE NO
LONGER DETERIORATING, AND THAT A HEALTHY PC MARKET SHOULD ALLOW A BETTER BALANCE
BETWEEN COMPONENT SUPPLY AND DEMAND.

    THE IMPROVEMENT IN THESE AREAS SHOULD ALSO PROVIDE THE CONDITIONS NECESSARY
FOR BETTER RELATIVE PERFORMANCE FROM ASIAN TECHNOLOGY SHARES. CONSEQUENTLY, WE
HAVE NOT REDUCED OUR ASIAN WEIGHTING TO FINANCE OUR INCREASED US EXPOSURE, BUT
HAVE INSTEAD CUT BACK ON OUR EUROPEAN POSITIONS. IN SO DOING WE HAVE TAKEN
PROFITS IN SOME OF OUR MOST SUCCESSFUL HOLDINGS SUCH AS COLT Telecom Group,
Vodafone, CMG, AND Logica.

SUMMARY
The recent spectacular rise in both markets and technology shares has taken us
back into more neutral territory. However, we expect that the sector will enjoy
another upward leg over the next several months, even if a pause occurs in the
very short term. Confidence is slowly rebuilding; demand in the PC and
networking markets remains robust, and at the margin, is improving in the
components, communications, and wireless areas. Year 2000 issues may have the
effect of concentrating corporate information technology (IT) demand into the
first half of next year, thereby encouraging investors to chase (what may prove
to be unsustainable) earnings momentum in the sector. European demand is proving
resilient in the face of the global economic slowdown, a reflection of the far
lower rates of IT penetration in Europe as compared to the US. Asian demand,
although depressed, should be improving by the second half of 1999.
Consequently, we anticipate further strength in the technology sector and do not
expect any significant setbacks in early 1999, and if setbacks should occur
then, they will be from considerably higher levels than at the end of October
1998.

   Performance  data  quoted  represent  changes in prices  and assume  that all
distributions within the periods are invested in additional shares. The rates of
return  will  vary and the  principal  value of an  investment  will  fluctuate.
Shares, if redeemed, may be worth more or less than their original cost.


- ------------------
    * Returns for periods of less than one year are not annualized.
   ** Return  figures  reflect any change in price and assume the investment of
      dividends  and capital gain  distributions. Returns for Class A shares are
      calculated  with and without the effect of the initial 4.75% maximum sales
      charge.  Returns  for Class B shares are calculated  with and  without the
      effect of the maximum 5% contingent deferred sales charge ("CDSC"),charged
      on redemptions  made within one year of the date of purchase, declining to
      1% in the sixth  year and 0%  thereafter.  Returns  for Class D shares are
      calculated  with  and  without  the  effect  of the  1%  CDSC,  charged on
      redemptions  made within one year of the date of  purchase.

      dividends.  The Lipper Global  Funds  Average  and  the Lipper  Science  &

      World  Index  excludes the effect of fees and sales charges.  The monthly

PERFORMANCE AND PORTFOLIO OVERVIEW
Seligman Henderson Global Technology Fund

  This  chart  compares  a  $10,000  hypothetical  investment  made in  Seligman
Henderson  Global  Technology  Fund,  with and without the initial 4.75% maximum
sales charge for Class A shares,  and without the 1% contingent  deferred  sales
charge  ("CDSC")  for Class D shares,  and assumes  that all  distributions  are
invested in additional  shares,  since the commencement of operations on May 23,
1994, through October 31, 1998, to a $10,000 hypothetical investment made in the
Lipper Global Funds Average,  the Lipper Science &Technology Funds Average,  and
the Morgan Stanley Capital  International World Index (MSCI World Index) for the
same period.  It is important to keep in mind that indices and averages  exclude
the effect of fees and/or sales charges.

  There are specific risks  associated with global  investing,  such as currency
fluctuations,  foreign taxation,  differences in financial reporting  practices,
and rapid changes in political and economic conditions.
  As shown on page 54, the performance of Class B shares will be greater than or
less than the performances shown for Class A shares and Class D shares, based on
the differences in sales charges and fees paid by shareholders. Past performance
is not indicative of future investment results.

NOTES TO FINANCIAL STATEMENTS


1. MULTIPLE CLASSES OF SHARES -- Seligman Henderson Global Fund Series, Inc.
(the "Fund") consists of five separate Series: Seligman Henderson International
Fund (the "International Fund"), Seligman Henderson Emerging Markets Growth Fund
(the "Emerging Markets Growth Fund"), Seligman Henderson Global Growth
Opportunities Fund (the "Global Growth Opportunities Fund"), Seligman Henderson
Global Smaller Companies Fund (the "Global Smaller Companies Fund"), and
Seligman Henderson Global Technology Fund (the "Global Technology Fund"). Each
Series of the Fund offers three classes of shares.

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

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

a. SECURITY VALUATION -- Securities traded on an exchange 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. Other securities not listed on an exchange or security
   market, or securities for which there is no last sales price, are valued at
   the mean of the most recent bid and asked prices. Any securities for which
   recent market quotations are not readily available are valued at fair value
   determined in accordance with procedures approved by the Board of Directors.
   Short-term holdings which mature in more than 60 days are valued at current
   market quotations. Short-term holdings maturing in 60 days or less are valued
   at amortized cost.

b. FOREIGN SECURITIES -- Investments in foreign securities will primarily be
   traded in foreign currencies, and each Series may temporarily hold funds in
   foreign currencies. The books and records of the Fund are maintained in US
   dollars. Foreign currency amounts are translated into US dollars on the
   following basis:

      (i) market value of investment securities, other assets, and liabilities,
      at the daily rate of exchange as reported by a pricing service;

      (ii) purchases and sales of investment securities, income, and expenses,
      at the rate of exchange prevailing on the respective dates of such
      transactions.


     The Fund's net asset values per share will be affected by changes in
currency exchange rates. Changes in foreign currency exchange rates may also
affect the value of dividends and interest earned, gains and losses realized on
sales of securities, and net investment income and gains, if any, which are to
be distributed to shareholders of the Fund. The rate of exchange between the US
dollar and other currencies is determined by the forces of supply and demand in
the foreign exchange markets.

     Net realized foreign exchange gains and losses arise from sales of
portfolio securities, sales and maturities of short-term securities, sales of
foreign currencies, currency gains or losses realized between the trade and
settlement dates on securities transactions, and the difference between the
amounts of dividends, interest, and foreign withholding taxes recorded on the
Fund's books, and the US dollar equivalents of the amounts actually received or
paid. Net unrealized foreign exchange gains and losses arise from changes in the
value of portfolio securities and other foreign currency denominated assets and
liabilities at period end, resulting from changes in exchange rates.

                                       67

<PAGE>

NOTES TO FINANCIAL STATEMENTS

     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. FORWARD CURRENCY CONTRACTS -- The Fund may enter into forward currency
   contracts in order to hedge its exposure to changes in foreign currency
   exchange rates on its foreign portfolio holdings, or other amounts receivable
   or payable in foreign currency. A forward contract is a commitment to
   purchase or sell a foreign currency at a future date at a negotiated forward
   rate. Certain risks may arise upon entering into these contracts from the
   potential inability of counterparties to meet the terms of their contracts.
   The contracts are valued daily at current exchange rates and any unrealized
   gain or loss is included in net unrealized appreciation or depreciation on
   translation of assets and liabilities denominated in foreign currencies and
   forward currency contracts. The gain or loss, if any, arising from the
   difference between the settlement value of the forward contract and the
   closing of such contract, is included in net realized gain or loss from
   foreign currency transactions.

d. FEDERAL TAXES -- There is no provision for federal income tax. Each Series
   has elected to be taxed as a regulated investment company and intends to
   distribute substantially all taxable net income and net gain realized, if
   any, annually. Withholding taxes on foreign dividends and interest have been
   provided for in accordance with the Fund's understanding of the applicable
   country's tax rules and rates. e. Security Transactions and Related
   Investment Income Investment transactions are recorded on trade dates.
   Identified cost of investments sold is used for both financial statement and
   federal income tax purposes. Dividends receivable and payable are recorded on
   ex-dividend dates, except that certain dividends from foreign securities
   where the ex-dividend dates may have passed are recorded as soon as the Fund
   is informed of the dividends. Interest income is recorded on an accrual
   basis.

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

g. DISTRIBUTIONS TO SHAREHOLDERS -- The treatment for financial statement
   purposes of distributions made to shareholders during the year from net
   investment income or net realized gains may differ from their ultimate
   treatment for federal income tax purposes. These differences primarily are
   caused by differences in the timing of the recognition of certain components
   of income, expense, or realized capital gain; and the recharacterization of
   foreign exchange gains or losses to either ordinary income or realized
   capital gains 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 reclassifications will have no effect on net assets, results of
   operations, or net asset value per share of the Fund.

     For the year ended October 31, 1998, the Global Technology Fund redeemed
42,108,514 of its shares from shareholders aggregating $548,141,848 of which
approximately $22,600,000 represents capital gain distributions. This
information is provided for federal income tax purposes only.

     On November 18, 1998, a distribution of $0.158 per share, aggregating
$9,093,102, was declared from net realized long-term gains from investment
transactions for the Global Technology Fund. The capital gain was paid on
November 23, 1998, to shareholders of record on November 18, 1998.

3. PURCHASES AND SALES OF SECURITIES -- Purchases and sales of portfolio
securities, excluding short-term investments, for the year ended October 31,
1998, were as follows:

       SERIES                      PURCHASES       SALES

4. MANAGEMENT FEE, DISTRIBUTION SERVICES, AND OTHER TRANSACTIONS -- J. & W.
Seligman & Co. Incorporated (the "Manager") manages the affairs of the Fund and
provides or arranges for the necessary personnel and facilities. The Manager
receives a fee, calculated daily and payable monthly, equal to 1.25% per annum
of the average daily net assets of the Emerging Markets Growth Fund and 1.00%
per annum of each of the other Series' average daily net assets. Prior to July
1, 1998, Seligman Henderson Co., an entity owned 50% each by the Manager and
Henderson International, Inc., a subsidiary of Henderson plc, supervised and
directed the Fund's global investments pursuant to subadvisory agreements with
the Manager. Under the subadvisory agreements, the Manager paid Seligman
Henderson Co. 1.15% per annum of the average daily net assets of the Emerging
Markets Growth Fund and 0.90% per annum of each of the other Series' average
daily net assets.

     On March 30, 1998, AMP Limited, an Australian life insurance and financial
services company, completed an acquisition of Henderson plc, which resulted in
the termination of the Fund's subadvisory agreements. The Fund's Board of
Directors approved interim subadvisory agreements pursuant to which Seligman
Henderson Co. continued to supervise and direct the Fund's global investments.
The Fund's directors also approved a proposed new subadvisory agreement pursuant
to which Henderson Investment Management Limited (the "Subadviser"), a
wholly-owned subsidiary of Henderson plc, would replace Seligman Henderson Co.
as subadviser to theFund and be responsible for furnishing investment advice,
research and assistance with respect to the Fund's international investments.
Under the new agreement, the Manager is responsible for the Fund's US
investments and has overall responsibility for management of the Fund. Both the
interim and the new subadvisory agreements were approved by vote of the
shareholders of the Fund on June 30, 1998. Under the new subadvisory agreement,
the Manager pays the Subadviser a subadvisory fee for each Series at a rate of
0.90% per annum of the average monthly assets under the Subadviser's
supervision.

     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 or by Henderson plc.

     Seligman Advisors, Inc. (the "Distributor") (formerly Seligman Financial
Services, Inc.), agent for the distribution of each Series' shares, and an
affiliate of the Manager, received concessions after commissions were paid to
dealers for sales of Class A shares as follows:

                                DISTRIBUTOR       DEALER

Global Technology Fund           121,127          978,251

     Each Series of the Fund has an Administration, Shareholder Services and
Distribution Plan (the "Plan") with respect to distribution of its shares. Under
the Plan, with respect to Class A shares, service organizations can enter into
agreements with the Distributor and receive a continuing fee of up to 0.25% on
an annual basis, payable quarterly, of the average daily net assets of the Class
A shares attributable to the particular service organizations for providing
personal services and/or the maintenance of shareholder accounts. The
Distributor charges such fees to the Fund pursuant to the Plan. For the year
ended October 31, 1998, fees incurred by the International Fund, the Emerging
Markets Growth Fund, the Global Growth Opportunities Fund, the Global Smaller
Companies Fund, and the Global Technology Fund aggregated $97,702, $80,916,
$261,123, $982,147, and $1,334,768, respectively, or 0.21%, 0.23%, 0.24%, 0.24%,
and 0.24%, respectively, per annum of the average daily net assets of Class A
shares.

     Under the Plan, with respect to Class B and Class D shares, service
organizations can enter into agreements with the Distributor and receive a
continuing fee for providing personal

                                       69

NOTES TO FINANCIAL STATEMENTS


services and/or the maintenance of shareholder accounts of up to 0.25% on an
annual basis of the average daily net assets of the Class B and Class D shares
for which the organizations are responsible; and, for Class D shares
only, fees for providing other distribution assistance of up to 0.75% on an
annual basis of such average daily net assets. Such fees are paid monthly by the
Fund to the Distributor pursuant to the Plan.

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

     For the year ended October 31, 1998, fees incurred under the Plan,
equivalent to 1% per annum of the average daily net assets of Class B and Class
D shares, were as follows:

     The Distributor has sold its rights to collect any CDSC imposed on
redemptions of Class B shares to the Purchaser. In connection with the sale of
its rights to collect any CDSC and the distribution fees with respect to Class B
shares described above, the Distributor receives payments from the Purchaser
based on the value of Class B shares sold. The aggregate amounts of such
payments and the Class B shares distribution fees retained by the Distributor
for the year ended October 31, 1998, were as follows:

5. COMMITTED LINE OF CREDIT -- Effective July 1, 1998,the F und terminated its
$100 million committed line of credit and entered into a joint $800 million
committed line of credit that is shared by substantially all funds in the
Seligman Group of Investment Companies. The Fund's borrowings are limited to 5%
of its net assets. Borrowings pursuant to the credit facility are subject to
interest at a rate equal to the overnight federal funds rate plus 0.50% on an
overnight basis. The Fund incurs a commitment fee of 0.80% per annum on its
share of the unused portion of the credit facility. The credit facility may be
drawn upon only for temporary purposes and is subject to certain other customary
restrictions. The credit facility commitment expires one year from the date of
the agreement but is renewable with the consent of the participating banks. To
date, the Fund has not borrowed from the credit facility.

6. LOSS CARRYFORWARD -- In accordance with current federal income tax law, each
of the Series' net realized capital gains and losses are considered separately
for purposes of determining taxable capital gains on an annual basis. At October
31, 1998, the Emerging Markets Growth Fund, the Global Growth Opportunities
Fund, and the Global Smaller Companies Fund had net capital loss carryforwards
for federal income tax purposes of $23,269,538, $1,139,976, and $22,271,988,
respectively, which are available for offsets against future taxable capital
gains, expiring in various amounts through 2006. Accordingly, no capital gain
distributions are expected to be paid to shareholders until net capital gains
have been realized in excess of the available capital loss carryforwards.

7. AFFILIATED ISSUERS -- As defined under the Investment Company Act of 1940, as
amended, affiliated issuers are those issuers in which a Series' holdings of an
issuer represent 5% or more of the outstanding voting securities of the issuer.

FINANCIAL HIGHLIGHTS

     The Fund's financial highlights are presented below. "Per share operating
performance" data is designed to allow investors to trace the operating
performance of each Class, on a per share basis, from the beginning net asset
value to the ending net asset value, so that investors can understand what
effect the individual items have on their investment, assuming it was held
throughout the period. Generally, the per share amounts are derived by
converting the actual dollar amounts incurred for each item, as disclosed in the
financial statements, to their equivalent per share amounts, based on average
shares outstanding.

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

REPORT OF INDEPENDENT AUDITORS


THE BOARD OF DIRECTORS AND SHAREHOLDERS,
SELIGMAN HENDERSON GLOBAL FUND SERIES, INC.:


We have audited the accompanying statements of assets and liabilities, including
the portfolios of investments,  of the International  Fund, the Emerging Markets
Growth Fund, the Global Growth  Opportunities Fund, the Global Smaller Companies
Fund, and the Global  Technology Fund Series of Seligman  Henderson  Global Fund
Series,  Inc. as of October 31, 1998,  the related  statements of operations for
the year then  ended and of  changes  in net assets for each of the years in the
two-year period then ended, and the financial highlights for each of the periods
presented.   These  financial   statements  and  financial  highlights  are  the
responsibility  of the Fund's  management.  Our  responsibility is to express an
opinion on these  financial  statements  and financial  highlights  based on our
audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned at October
31, 1998, by correspondence with the Fund's custodian and brokers; where replies
were not received from brokers, we performed other auditing procedures. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, such financial statements and financial highlights present
fairly, in all material respects, the financial position of each Series of
Seligman Henderson Global Fund Series, Inc. as of October 31, 1998, the results
of their operations, the changes in their net assets, and the financial
highlights for the respective stated periods in conformity with generally
accepted accounting principles.

GLOSSARY OF FINANCIAL TERMS


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

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

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

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

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

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

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

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

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

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

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


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

distributions are taken in additional fund shares. The AVERAGE ANNUAL TOTAL
RETURN represents the average annual compounded rate of return for the periods
presented.

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

Item  25.  Indemnification. Reference  is  made to the  provisions  of  Articles
- --------   ---------------
           Twelfth and Thirteenth of Registrant's  Amended and Restated Articles

           Insofar  as  indemnification   for  liabilities   arising  under  the

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

                             ARTICLES SUPPLEMENTARY

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

          FIRST:  (a) The  total  number  of  shares  of  capital  stock  of all
sub-classes of the Seligman  Henderson Emerging Markets Growth Fund Class of the
Corporation  (the "Emerging  Markets Growth  Series") which the  Corporation has
authority to issue is 400,000,000  shares,  which were previously  classified by
the Board of Directors of the Corporation into three classes designated as Class
A Common  Stock,  Class B Common  Stock and Class D Common Stock of the Emerging
Markets Growth Series.  The number of authorized shares of Class A Common Stock,
Class B Common  Stock and Class D Common Stock of the  Emerging  Markets  Growth
Series  each  consisted  of the sum of x and y,  where x equaled  the issued and
outstanding  shares of such sub-class and y equaled  one-third of the authorized
but unissued  shares of Common Stock of all  sub-classes;  PROVIDED  that at all
times the aggregate authorized,  issued and outstanding shares of Class A, Class
B and Class D Common  Stock of the  Emerging  Markets  Growth  Series  shall not
exceed the authorized  number of shares of Common Stock of the Emerging  Markets
Growth  Series;  and, in the event  application  of the formula above would have
resulted, at any time, in fractional shares, the applicable number of authorized
shares of each class was to have been rounded  down to the nearest  whole number
of shares of such sub-class.

          (b):  Pursuant to the  authority of the Board of Directors to classify
and reclassify unissued shares of capital stock of the Corporation, the Board of
Directors has reclassified the unissued shares of Class A Common Stock,  Class B
Common Stock and Class D Common Stock of the Emerging Markets Growth Series into
the  following  subclasses,  has  provided  for the  issuance  of shares of such
subclasses and has set the following terms of such subclasses:

          (1) The  total  number of shares  of all  classes  of stock  which the
     Emerging Markets Growth Series has authority to issue is 400,000,000 shares
     of  common  stock  ("Shares")  of the par  value of $.001  each  having  an
     aggregate par value of $400,000.  The Common Stock of the Emerging  Markets
     Growth  Series  shall  have  four  subclasses  of  shares,  which  shall be
     designated Class A Common Stock, Class B Common Stock, Class C Common Stock
     and Class D Common Stock. The number of authorized shares of Class A Common
     Stock,  of Class B Common  Stock,  of Class C Common  Stock  and of Class D
     Common Stock of the Emerging  Markets  Growth  Series shall each consist of
     the sum of x and y, where x equals the  issued  and  outstanding  shares of
     such subclass and y equals one-fourth of the authorized but unissued shares
     of Common Stock of all subclasses; PROVIDED that at all times the aggregate
     authorized,  issued and outstanding shares of Class A, Class B, Class C and
     Class D Common Stock of the Emerging Markets Growth Series shall not exceed
     the  authorized  number of shares of Common Stock of the  Emerging  Markets
     Growth  Series


                                      - 1 -
<PAGE>

     (I.E.,  400,000,000  shares of Common Stock until changed by further action
     of the  Board of  Directors  in  accordance  with  Section  2-208.1  of the
     Maryland General Corporation Law, or any successor provision);  and, in the
     event  application  of the formula  above  would  result,  at any time,  in
     fractional shares, the applicable number of authorized shares of each class
     shall be rounded down to the nearest  whole number of shares of such class.
     Any subclass of Common Stock of the Emerging Markets Growth Series shall be
     referred to herein  individually  as a "Emerging  Markets Growth Class" and
     collectively,  together with any further  subclass or sub classes from time
     to time established, as the "Emerging Markets Growth Classes".

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

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

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

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

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

          (E) Expenses  related solely to a particular  Emerging  Markets Growth
     Class (including,  without limitation,  distribution  expenses under a Rule
     12b-1 plan and  administrative  expenses under an administration or service
     agreement, plan or other arrangement,  however designated, which may differ
     between  the  Emerging  Markets  Growth  Classes)  shall  be  borne by that
     Emerging Markets Growth Class and shall

                                      - 2 -
<PAGE>

     be  appropriately  reflected  (in the  manner  determined  by the  Board of
     Directors) in the net asset value, dividends,  distribution and liquidation
     rights of the shares of that Emerging Markets Growth Class.

          (F) At such time as shall be permitted  under the  Investment  Company
     Act, any applicable rules and regulations  thereunder and the provisions of
     any exemptive order applicable to the Corporation, and as may be determined
     by the Board of Directors and  disclosed in the then current  prospectus of
     the Emerging Markets Growth Series, shares of a particular Emerging Markets
     Growth Class may be automatically converted into shares of another Emerging
     Markets Growth Class;  PROVIDED,  HOWEVER,  that such  conversion  shall be
     subject  to the  continuing  availability  of an  opinion of counsel to the
     effect  that such  conversion  does not  constitute  a taxable  event under
     Federal income tax law. The Board of Directors, in its sole discretion, may
     suspend any conversion rights if such opinion is no longer available.

          (G) As to any matter  with  respect  to which a  separate  vote of any
     Emerging Markets Growth Class is required by the Investment  Company Act or
     by the Maryland  General  Corporation Law (including,  without  limitation,
     approval  of any  plan,  agreement  or  other  arrangement  referred  to in
     subsection  (E)  above),  such  requirement  as to a  separate  vote by the
     Emerging  Markets  Growth  Class  shall  apply in lieu of  single  Emerging
     Markets Growth Class voting,  and, if permitted by the  Investment  Company
     Act or any rules, regulations or orders thereunder and the Maryland General
     Corporation Law, the Emerging Markets Growth Classes shall vote together as
     a single  Emerging  Markets Growth Class on any such matter that shall have
     the same  effect on each such  Emerging  Markets  Growth  Class.  As to any
     matter that does not affect the interest of a particular  Emerging  Markets
     Growth Class,  only the holders of shares of the affected  Emerging Markets
     Growth Class shall be entitled to vote.

          SECOND:  (a) The  total  number  of  shares  of  capital  stock of all
sub-classes of the Seligman Henderson Global Growth  Opportunities Fund Class of
the Corporation (the "Global Growth Series") which the Corporation has authority
to issue is 400,000,000 shares, which were previously classified by the Board of
Directors of the  Corporation  into three  classes  designated as Class A Common
Stock,  Class B Common  Stock  and  Class D Common  Stock of the  Global  Growth
Series.  The number of authorized shares of Class A Common Stock, Class B Common
Stock and Class D Common Stock of the Global Growth Series each consisted of the
sum of x and y,  where x  equaled  the  issued  and  outstanding  shares of such
sub-class  and y equaled  one-third of the  authorized  but  unissued  shares of
Common  Stock of all  sub-classes;  PROVIDED  that at all  times  the  aggregate
authorized, issued and outstanding shares of Class A, Class B and Class D Common
Stock of the Global  Growth  Series  shall not exceed the  authorized  number of
shares  of  Common  Stock  of the  Global  Growth  Series;  and,  in  the  event
application of the formula above would have resulted, at any time, in fractional
shares,  the  applicable  number of authorized  shares of each class was to have
been rounded down to the nearest whole number of shares of such sub-class.

          (b):  Pursuant to the  authority of the Board of Directors to classify
and reclassify unissued shares of capital stock of the Corporation, the Board of
Directors has reclassified the unissued shares of Class A Common Stock,  Class B
Common  Stock and Class D Common  Stock of the  Global  Growth  Series  into the
following subclasses, has provided for the issuance of shares of such subclasses
and has set the following terms of such subclasses:

          (1) The  total  number of shares  of all  classes  of stock  which the
     Global Growth Series has authority to issue is 400,000,000 shares of common
     stock  ("Shares")  of the par value of $.001 each having an  aggregate  par
     value of $400,000.  The Common Stock of the Global Growth Series shall have
     four subclasses of shares,  which shall be designated Class A Common Stock,
     Class B Common Stock,  Class C Common Stock and Class D Common  Stock.  The
     number  of  authorized  shares of Class A Common  Stock,  of Class B Common
     Stock,  of Class C Common  Stock and of Class D Common  Stock of the Global
     Growth  Series shall each consist of the sum of x and y, where x equals the
     issued and outstanding  shares of such subclass and y equals  one-fourth of
     the  authorized  but  unissued  shares of Common  Stock of all  subclasses;
     PROVIDED that at all times the aggregate authorized, issued and outstanding
     shares of Class A, Class B, Class C and Class D Common  Stock of the Global
     Growth  Series shall not exceed the  authorized  number of shares of Common
     Stock of the Global Growth Series (I.E., 400,000,000 shares of Common Stock
     until  changed by further  action of the Board of Directors  in  accordance
     with  Section  2-208.1 of the  Maryland  General  Corporation  Law,  or any
     successor  provision);  and, in the event  application of the formula above
     would result, at any time, in fractional  shares,  the applicable number of
     authorized  shares of each class shall be rounded down to the nearest whole
     number of shares of such class.  Any subclass of Common Stock of the Global
     Growth Series shall be referred to herein  individually as a "Global Growth
     Class" and collectively,  together with any further subclass or sub classes

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

               (A) Class A shares may be subject to such  front-end  sales loads
          as may be  established  by the Board of Directors from time to time in
          accordance  with the Investment  Company Act and applicable  rules and

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

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

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

               (F) At such  time as  shall be  permitted  under  the  Investment
          Company Act, any applicable  rules and regulations  thereunder and the
          provisions of any exemptive order applicable to the  Corporation,  and
          as may be  determined  by the Board of Directors  and disclosed in the
          then  current  prospectus  of the Global  Growth  Series,  shares of a
          particular  Global Growth Class may be  automatically  converted  into
          shares of another Global Growth Class;  PROVIDED,  HOWEVER,  that such
          conversion  shall be  subject  to the  continuing  availability  of an
          opinion  of  counsel  to the  effect  that  such  conversion  does not
          constitute a taxable event under Federal  income tax law. The Board of
          Directors,  in its sole discretion,  may suspend any conversion rights
          if such opinion is no longer available.

               (G) As to any matter with respect to which a separate vote of any
          Global  Growth Class is required by the  Investment  Company Act or by
          the Maryland General  Corporation Law (including,  without limitation,
          approval of any plan,  agreement or other  arrangement  referred to in
          subsection (E) above),  such  requirement as to a separate vote by the
          Global  Growth Class shall apply in lieu of single Global Growth Class
          voting,  and, if permitted by the Investment Company Act or any rules,
          regulations or orders thereunder and the Maryland General  Corporation
          Law, the Global Growth  Classes shall vote together as a single Global
          Growth  Class on any such  matter  that shall have the same  effect on
          each such Global Growth  Class.  As to any matter that does not affect
          the interest of a particular  Global Growth Class, only the holders of
          shares of the affected Global Growth Class shall be entitled to vote.

     THIRD: (a) The total number of shares of capital stock of all subclasses of
the Seligman  Henderson  Global Smaller  companies Fund Class of the Corporation
(the "Global Smaller  Companies  Series") which the Corporation has authority to
issue is 400,000,000  shares,  which were previously  classified by the Board of
Directors of the  Corporation  into three  classes  designated as Class A Common
Stock,  Class B Common  Stock and  Class D Common  Stock of the  Global  Smaller
Companies Series. The number of authorized shares of Class A Common Stock, Class
B Common Stock and Class D Common Stock of the Global Smaller  Companies  Series
each consisted of the sum of x and y, where x equaled the issued and outstanding
shares of such subclass and y equaled  one-third of the  authorized but unissued
shares of Common Stock of all classes of the Global  Smaller  Companies  Series;
PROVIDED  that at all times the  aggregate  authorized,  issued and  outstanding
shares  of  Class A,  Class B and  Class D Common  Stock of the  Global  Smaller
Companies  Series  shall not  exceed the  authorized  number of shares of Common
Stock of the Global Smaller Companies  Series;  and, in the event application of
the formula above would have resulted,  at any time, in fractional  shares,  the
applicable number of authorized shares of each subclass was to have been rounded
down to the nearest whole number of shares of such subclass.

     (b):  Pursuant to the  authority  of the Board of Directors to classify and
reclassify  unissued  shares of capital stock of the  Corporation,  the Board of
Directors has reclassified the unissued shares of Class A Common Stock,  Class B
Common Stock and Class D Common  Stock of the Global  Smaller  Companies  Series
into the following  subclasses,  has provided for the issuance of shares of such
subclasses and has set the following terms of such sub-classes.

          (1) The  total  number of shares  of all  classes  of stock  which the
     Global  Smaller  Companies  Series has  authority  to issue is  400,000,000
     shares of common stock  ("Shares") of the par value of $.001 each having an
     aggregate  par value of $400,000.  The Common  Stock of the Global  Smaller
     Companies  Series  shall have four  subclasses  of shares,  which  shall be
     designated Class A Common Stock, Class B Common Stock, Class C Common Stock
     and Class D Common Stock. The number of authorized shares of Class A Common
     Stock,  of Class B Common  Stock,  of Class C Common  Stock  and of Class D
     Common Stock of the Global Smaller  Companies  Series shall each consist of
     the sum of x and y, where x equals the  issued  and  outstanding  shares of
     such subclass and y equals one-fourth of the authorized but unissued shares
     of Common Stock of all subclasses of the Global Smaller  Companies  Series;
     PROVIDED that at all times the aggregate authorized, issued and outstanding
     shares of Class A, Class B, Class C and Class D Common  Stock of the Global
     Smaller  Companies Series shall not exceed the authorized  number of shares
     of Common Stock of the Global Smaller  Companies Series (I.E.,  400,000,000
     shares of Common  Stock  until  changed by  further  action of the Board of
     Directors  in  accordance  with  Section  2-208.1 of the  Maryland  General
     Corporation Law, or any successor provision); and, in the event application
     of the formula above would result, at any time, in fractional  shares,  the
     applicable  number of authorized  shares of each subclass  shall be rounded
     down to the nearest whole number of shares of such  subclass.  Any subclass
     of Common Stock of the Global Smaller Companies Series shall be referred to
     herein individually as a "Global Smaller Companies Class" and collectively,
     together  with  any  further  subclass  or  subclasses  from  time  to time
     established, as the "Global Smaller Companies Classes".

          (B) Class B shares may be subject to such  contingent  deferred  sales
     charges as may be  established  from time to time by the Board of Directors

     regulations  of the NASD.  Subject to  subsection  (F) below,  each  Global
     Smaller  Companies  Class B share shall convert  automatically  into Global
     Smaller Companies Class A shares on the last business day of the month that
     precedes  the eighth  anniversary  of the date of  issuance  of such Global
     Smaller  Companies Class B share;  such conversion shall be effected on the
     basis of the relative net asset values of Global Smaller  Companies Class B
     shares and Global  Smaller  Companies  Class A shares as  determined by the
     Corporation on the date of conversion.

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

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

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

          (F) At such time as shall be permitted  under the  Investment  Company
     Act, any applicable rules and regulations  thereunder and the provisions of
     any exemptive order applicable to the Corporation, and as may be determined
     by the Board of Directors and  disclosed in the then current  prospectus of
     the Global Smaller Companies Series,  shares of a particular Global Smaller
     Companies  Class may be  automatically  converted  into  shares of  another
     Global Smaller  Companies Class;

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

          (G) As to any matter  with  respect  to which a  separate  vote of any
     Global Smaller Companies Class is required by the Investment Company Act or
     by the Maryland  General  Corporation Law (including,  without  limitation,
     approval  of any  plan,  agreement  or  other  arrangement  referred  to in
     subsection  (E)  above),  such  requirement  as to a separate  vote by that
     Global Smaller Companies Class shall apply in lieu of single Global Smaller
     Companies Class voting,  and, if permitted by the Investment Company Act or
     any  rules,  regulations  or orders  thereunder  and the  Maryland  General
     Corporation Law, the Global Smaller  Companies  Classes shall vote together
     as a single Global  Smaller  Companies  Class on any such matter that shall
     have the same effect on each such Global Smaller Companies Class. As to any
     matter that does not affect the  interest of a  particular  Global  Smaller
     Companies Class,  only the holders of shares of the affected Global Smaller
     Companies Class shall be entitled to vote.

     FOURTH:  (a) The total number of shares of capital stock of all  subclasses
of the Seligman  Henderson Global  Technology Fund Class of the Corporation (the
"Global  Technology  Series")  which the  Corporation  has authority to issue is
400,000,000 shares,  which were previously  classified by the Board of Directors
of the Corporation into three classes  designated as Class A Common Stock, Class
B Common Stock and Class D Common  Stock of the Global  Technology  Series.  The
number of authorized  shares of Class A Common  Stock,  Class B Common Stock and
Class D Common Stock of the Global  Technology  Series each consisted of the sum
of x and y, where x equaled the issued and  outstanding  shares of such subclass
and y equaled one-third of the authorized but unissued shares of Common Stock of
all subclasses of the Global Technology  Series;  PROVIDED that at all times the
aggregate  authorized,  issued  and  outstanding  shares of Class A, Class B and
Class D Common  Stock of the  Global  Technology  Series  shall not  exceed  the
authorized  number of shares of Common  Stock of the Global  Technology  Series;
and, in the event  application of the formula above would have resulted,  at any
time, in fractional  shares,  the applicable number of authorized shares of each
subclass was to have been rounded down to the nearest  whole number of shares of
such subclass.

     (b):  Pursuant to the  authority  of the Board of Directors to classify and
reclassify  unissued  shares of capital stock of the  Corporation,  the Board of
Directors has reclassified the unissued shares of Class A Common Stock,  Class B
Common  Stock  and  Class D Common  Stock  into the  following  subclasses,  has
provided  for the  issuance  of  shares  of such  subclasses  and  have  set the
following terms of such subclasses:

     Global  Technology  Series has authority to issue is 400,000,000  shares of
     common stock  ("Shares") of the par value of $.001 each having an aggregate
     par value of  $400,000.  The

     Common Stock of all  subclasses;  PROVIDED  that at all times the aggregate
     authorized,  issued and outstanding shares of Class A, Class B, Class C and
     Class D Common Stock of the Global  Technology  Series shall not exceed the
     authorized  number of shares of Common Stock (I.E.,  400,000,000  shares of
     Common  Stock of the  Global  Technology  Series  until  changed by further
     action of the Board of Directors in accordance  with Section 2-208.1 of the
     Maryland General Corporation Law, or any successor provision);  and, in the
     event  application  of the formula  above  would  result,  at any time,  in
     fractional shares, the applicable number of authorized shares of each class
     shall be  rounded  down to the  nearest  whole  number  of  shares  of such
     subclass.  Any  subclass of Common  Stock of the Global  Technology  Series
     shall be referred to herein individually as a "Global Technology Class" and
     collectively, together with any further subclass or subclasses from time to
     time established, as the "Global Technology Classes".

     (2) All Global Technology  Classes shall represent the same interest in the

     Technology Class B share shall convert automatically into Global Technology
     Class A shares on the last  business  day of the month  that  precedes  the
     eighth  anniversary of the date of issuance of such Global Technology Class
     B share; such conversion shall be effected on the basis of the relative net
     asset  values of Global  Technology  Class B shares and  Global  Technology
     Class A shares as determined by the Corporation on the date of conversion.

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

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

     Act, any applicable rules and regulations  thereunder and the provisions of
     any exemptive order applicable to the Corporation, and as may be determined
     by the Board of Directors and  disclosed in the then current  prospectus of
     the Global  Technology  Series,  shares of a particular  Global  Technology
     Class  may  be  automatically  converted  into  shares  of  another  Global
     Technology Class; PROVIDED,  HOWEVER, that such conversion shall be subject
     to the continuing  availability of an opinion of counsel to the effect that
     such  conversion  does not  constitute a taxable event under Federal income
     tax law. The Board of Directors,  in its sole  discretion,  may suspend any
     conversion rights if such opinion is no longer available.

          (G) As to any matter  with  respect  to which a  separate  vote of any
     Global Technology Class is required by the Investment Company Act or by the
     Maryland General Corporation Law (including,  without limitation,  approval
     of any plan,  agreement or other arrangement  referred to in subsection (E)
     above),  such  requirement as to a separate vote by that Global  Technology
     Class shall apply in lieu of single Global Technology Class voting, and, if
     permitted by the Investment Company Act or any rules, regulations or orders
     thereunder and the Maryland General  Corporation Law, the Global Technology
     Classes shall vote together as a single Global Technology Class on any such
     matter that shall have the same effect on each such Class. As to any matter
     that does not affect the interest of a particular  Global Technology Class,

     entitled to vote.

     FIFTH: (a) The total number of shares of capital stock of all subclasses of

400,000,000 shares,  which were previously  classified by the Board of Directors
of the  Corporation  into three  subclasses  designated as Class A Common Stock,
Class B Common Stock and Class D Common Stock of the International  Series.  The
number of authorized  shares of Class A Common  Stock,  Class B Common Stock and
Class D Common Stock of the International  Series each consisted of the sum of x
and y, where x equaled


                                     - 10 -
<PAGE>

the issued and  outstanding  shares of such subclass and y equaled  one-third of
the  authorized  but unissued  shares of Common Stock of all  subclasses  of the
International  Series;  PROVIDED  that at all  times the  aggregate  authorized,
issued and  outstanding  shares of Class A, Class B and Class D Common  Stock of
the  International  Series shall not exceed the  authorized  number of shares of
Common Stock of the International  Series;  and, in the event application of the
formula  above would have  resulted,  at any time,  in  fractional  shares,  the
applicable number of authorized shares of each subclass was to have been rounded
down to the nearest whole number of shares of such subclass.

     (b)  Pursuant to the  authority  of the Board of  Directors to classify and
reclassify  unissued  shares of capital stock of the  Corporation,  the Board of
Directors has reclassified the unissued shares of Class A Common Stock,  Class B
Common  Stock  and  Class  D of the  International  Series  into  the  following
subclasses,  has provided for the issuance of shares of such  subclasses and has
set the following terms of such subclasses:.

          (1) The  total  number of shares  of all  classes  of stock  which the
     International Series has authority to issue is 400,000,000 shares of common
     stock  ("Shares")  of the par value of $.001 each having an  aggregate  par
     value of $400,000.  The Common Stock of the International Series shall have
     four subclasses of shares,  which shall be designated Class A Common Stock,
     Class B Common Stock,  Class C Common Stock and Class D Common  Stock.  The
     number  of  authorized  shares of Class A Common  Stock,  of Class B Common
     Stock,  of Class C Common  Stock  and of Class D Common  Stock  shall  each
     consist of the sum of x and y,  where x equals  the issued and  outstanding
     shares of such  subclass  and y equals  one-fourth  of the  authorized  but
     unissued  shares of Common  Stock of all  subclasses  of the  International
     Series;  PROVIDED  that at all times the aggregate  authorized,  issued and
     outstanding shares of Class A, Class B, Class C and Class D Common Stock of
     the  International  Series shall not exceed the authorized number of shares
     of Common Stock of the International Series (I.E., 400,000 shares of Common
     Stock  until  changed  by  further  action  of the  Board of  Directors  in
     accordance with Section 2-208.1 of the Maryland General Corporation Law, or
     any  successor  provision);  and, in the event  application  of the formula
     above would  result,  at any time,  in fractional  shares,  the  applicable
     number of authorized  shares of each subclass  shall be rounded down to the
     nearest  whole  number of shares of such  subclass.  Any subclass of Common
     Stock of the International  Series shall be referred to herein individually
     as an  "International  Class" and  collectively,  together with any further
     subclass or subclasses from time to time established, as the "International
     Classes".

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

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

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

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

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

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

               (F) At such  time as  shall be  permitted  under  the  Investment
          Company Act, any applicable  rules and regulations  thereunder and the
          provisions of any exemptive order applicable to the  Corporation,  and
          as may be  determined  by the Board of Directors  and disclosed in the
          then  current  prospectus  of the  International  Series  shares  of a
          particular  International  Class may be  automatically  converted into
          shares of another  International Class;  PROVIDED,  HOWEVER, that such
          conversion  shall be  subject  to the  continuing  availability  of an
          opinion  of  counsel  to the  effect  that  such  conversion  does not
          constitute a taxable event under Federal  income tax law. The Board of
          Directors,  in its sole discretion,  may suspend any conversion rights
          if such opinion is no longer available.

               (G) As to any matter with respect to which a separate vote of any
          International  Class is required by the  Investment  Company Act or by
          the Maryland General  Corporation Law (including,  without limitation,
          approval of any plan,  agreement or other  arrangement  referred to in
          subsection (E) above),  such requirement as to a separate vote by that
          International Class shall apply in lieu of


                                     - 12 -

          single International Class voting, and, if permitted by the Investment
          Company Act or any rules,  regulations  or orders  thereunder  and the
          Maryland General Corporation Law, the International Classes shall vote
          together as a single International Class on any such matter that shall
          have the same  effect  on each  such  International  Class.  As to any
          matter that does not affect the interest of a particular International
          Class, only the holders of shares of the affected  International Class
          shall be entitled to vote.

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

     IN WITNESS WHEREOF,  SELIGMAN HENDERSON GLOBAL FUND SERIES, INC. has caused
these Articles  Supplementary  to be signed in its name and on its behalf by its
President  and  witnessed  by its  Secretary,  and each of said  officers of the

Seligman Henderson Global Fund Series, Inc.,
   100 Park Avenue,
   New York, N.Y.  10017.


Dear Sirs:


     In  connection  with  Post-Effective  Amendment  No.28 to the  Registration
Statement  on Form N-1A (File No.  33-44186) of Seligman  Henderson  Global Fund
Series,  Inc., a Maryland  corporation  (the  "Fund"),  which you expect to file
under the  Securities  Act of 1933,  as amended  (the  "Securities  Act"),  with
respect to an indefinite number of shares of capital stock, par value $0.001 per
share, of the class designated as Class C shares (the "Shares") of the series of
the Fund designated as Seligman Henderson International Fund, Seligman Henderson
Emerging Markets Growth Fund,  Seligman  Henderson  Global Growth  Opportunities
Fund,  Seligman  Henderson Global Smaller Companies Fund and Seligman  Henderson
Global Technology Fund (collectively,  the "Series"),  we, as your counsel, have
examined such corporate  records,  certificates  and other  documents,  and such
questions  of law,  as we  have  considered  necessary  or  appropriate  for the
purposes of this opinion.

     The  number of shares of each class of  capital  stock that each  Series is
authorized  to issue at any time is determined by adding to the number of shares
of such  class  then  outstanding  additional  authorized  shares  in an  amount
determined  according to a formula set forth in the Fund's charter.  The formula
allocates  to each class an equal  portion of the number of shares  representing
the  difference  between the number of shares that the Series is  authorized  to
issue and the total  number of shares of all classes of such Series  outstanding
at such time.


<PAGE>



     Upon the basis of such examination, we advise you that, in our opinion, the
Fund is  authorized  to issue the number of Shares of each Series  determined in
accordance  with  the  charter  of the Fund as  described  above  and,  when the
Post-Effective  Amendment  referred  to above  has  become  effective  under the
Securities  Act and the Shares  have been  issued (a) for at least the par value
thereof in accordance with the Registration  Statement referred to above, (b) so
as not to exceed the then authorized  number of Shares of such Series and (c) in
accordance with the authorization of the Board of Directors,  the Shares will be
duly and validly issued, fully paid and non-assessable.

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

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


                                                    Very truly yours,

                                                    SULLIVAN & CROMWELL


                                      -2-



                        CONSENT OF INDEPENDENT AUDITORS

Seligman Henderson Global Fund Series, Inc.:

We  consent  to the  use in  Post-Effective  Amendment  No.  28 to  Registration
Statement No.  33-44186 of our report dated  December 4, 1998,  appearing in the
Annual Report to Shareholders for the year ended October 31, 1998,  incorporated
by reference in the Statement of Additional Information, and to the reference to
us under the caption  "Financial  Highlights" in the  Prospectus,  which is also
part of such Registration Statement.

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

                  As amended and restated through June 1, 1999

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

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

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

                  SECTION 4. This Plan shall continue in effect through December
31 of each year so long as such  continuance is  specifically  approved at least
annually by vote of a majority of both

                                       1
<PAGE>

(a)  the Directors of the Fund and (b) the Qualified  Directors,  cast in person
at a meeting  called  for the  purpose of voting on such approval.

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

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

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

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

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

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

                  SECTION   9.  The   Series  is  not   obligated   to  pay  any
administration,  shareholder  services or distribution  expense in excess of the
fee  described  in  Section 2 hereof,  and,  in the case of Class A shares,  any
expenses of  administration,  shareholder  services and  distribution of Class A

                                       2
<PAGE>

shares of the Series  accrued  in one fiscal  year of the Series may not be paid
from  administration,  shareholder  services and distribution fees received from
the Series in respect of Class A shares in any other fiscal year.

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

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

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

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

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

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

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

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

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

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

                  As amended and restated through June 1, 1999

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

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

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

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

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

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

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

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

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

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

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

                  As amended and restated through June 1, 1999

                  SECTION 1. Seligman  Henderson  Global Smaller  Companies Fund
(the "Series"),  a series of Seligman  Henderson  Global Fund Series,  Inc. (the

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

                  SECTION 1.  Seligman  Henderson  Global  Technology  Fund (the
"Series"),  a series of Seligman Henderson Global Fund Series, Inc. (the "Fund")
will pay fees to Seligman  Advisors,  Inc.,  the  principal  underwriter  of its
shares  (the  "Distributor"),  for  administration,   shareholder  services  and

Organization provides administration, accounting and other shareholder services,
payment  for which is not  required to be made  pursuant  to a plan  meeting the
requirements  of Rule  12b-1,  a portion of the fee paid by the Series  shall be
deemed to include  compensation  for such  services.  The fees received from the
Series  hereunder  in  respect  of the Class A shares may not be used to pay any
interest  expense,  carrying charges or other financing costs, and fees received
hereunder may not be used to pay any allocation of overhead of the  Distributor.
The fees of any particular  class of the Series may not be used to subsidize the

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

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

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

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

                  SECTION 8. This Plan may not be amended to increase materially

of a majority of the outstanding  voting securities of the relevant class and no
material  amendment  to this  Plan  shall be  approved  other  than by vote of a
majority of both (a) the Directors of the Fund and (b) the Qualified  Directors,
cast in person at a meeting  called for the purpose of voting on such  approval.
This Plan shall not be amended to reduce  the  distribution  fee  payable to the
Distributor  pursuant  to Section 2 hereof in respect of Class B shares,  unless
the  shareholder  servicing  fee  payable  pursuant  to  Section  2  hereof  for
compensation to Service Organizations for providing  administration,  accounting
and other shareholder services has been eliminated,  provided,  however that the
distribution  fee in respect of Class B shares may be reduced  without change to

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