The Fund and the Portfolio

OVERVIEW OF THE FUND

Seligman Portfolios, Inc. (the Fund) consists of 15 separate portfolios. This
Prospectus contains information about Seligman Bond Portfolio (the Portfolio).


The Portfolio is offering its shares only to separate accounts (Accounts) of
participating insurance companies to fund benefits of variable annuity and
variable life insurance contracts (Contracts). The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.

The Portfolio offers two classes of shares: Class 1 shares and Class 2 shares.
This Prospectus offers only Class 1 shares and is for use with Accounts that
make Class 1 shares available to Contract owners.


INVESTMENT OBJECTIVE

The Portfolio's objective is favorable current income.

PRINCIPAL INVESTMENT STRATEGIES

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

Generally, the Portfolio invests in fixed-income securities, diversified among a
number of market sectors. The Portfolio has a fundamental policy that at least
80% of the Portfolio's assets will be invested in securities that are rated
investment-grade when purchased by the Portfolio. The Portfolio may invest in
securities of any duration. Capital appreciation is a secondary consideration in
selecting securities for purchase by the Portfolio. The Portfolio may invest in
corporate debt securities (including bonds and debentures convertible into
common stock or with rights and warrants), securities issued or guaranteed by
the US Treasury, its agencies or instrumentalities, mortgage-backed securities
(including collateralized mortgage obligations and mortgage pass-through
securities), and high-grade money market instruments. The Portfolio may also
hold or sell any securities obtained through the exercise of conversion rights
or warrants, or as a result of a reorganization, recapitalization, or
liquidation proceeding of any issuer of securities owned by the Portfolio.

The Portfolio's investment approach combines macro analysis of the fixed-income
market with fundamental research into individual securities, customized by
market sector. This means that the investment manager considers the trends in
the fixed-income market and evaluates the long-term trends in interest rates,
and then selects individual securities for the Portfolio based on its evaluation
of each security's particular characteristics (for example, duration, yield,
quality, relative value). The average maturity of the Portfolio will vary in
response to what the investment manager believes to be the long-term trend in
interest rates. Generally, if rates are trending up, the Portfolio will tend to
hold securities with shorter maturities. If rates are trending down, the
Portfolio will tend to hold securities with longer maturities. Additionally, the
Portfolio's concentration in any particular market sector and the Portfolio's
individual security holdings will vary depending on the investment manager's
view of the relative value offered by certain sectors, as well as specific
securities within those sectors.

In selecting individual securities for purchase by the Portfolio, the investment
manager will seek to identify securities of various market sectors that it
believes offer better total return opportunities.

The Portfolio generally sells securities when the investment manager believes
that the direction of long-term interest rates is changing, better opportunities
exist in the market, or yield spreads (i.e., the yields offered on different
securities) have become too narrow to justify the added volatility of long-term
securities (which generally offer higher yields), or when the Portfolio must
meet cash requirements.


                                      P-1
<PAGE>


The Portfolio may invest up to 15% of its net assets in illiquid securities
(i.e., securities that cannot be readily sold), and may invest up to 10% of its
total assets directly in foreign securities. The Portfolio may purchase
securities on a when-issued or forward commitment basis (delivery of securities
and payment of the purchase price takes place after the commitment to purchase
the securities). The Portfolio generally does not invest a significant amount,
if any, in illiquid or foreign securities.

The Portfolio may change its principal strategies, except for stated fundamental
policies, if the Fund's Board of Directors believes doing so is consistent with
the Portfolio's objective. The Portfolio's objective and any fundamental
policies may be changed only with shareholder approval. If a change of objective
or fundamental policies is proposed, Contract owners will be asked to give
voting instructions to the participating insurance companies.

The Portfolio 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 Portfolio from achieving its objective.

There is no guarantee that the Portfolio will achieve its objective.

PRINCIPAL RISKS

The value of your investment in the Portfolio will fluctuate with fluctuations
in the value of the securities held by the Portfolio. The principal factors that
may affect the value of the Portfolio's securities holdings are changes in
interest rates and the credit worthiness of the issuers of securities held by
the Portfolio.

Interest rate risk. Changes in market interest rates will affect the value of
securities held by the Portfolio. The Portfolio invests mostly in fixed-income
securities. In general, the market value of fixed-income securities moves in the
opposite direction of interest rates: the market value decreases when interest
rates rise and increases when interest rates fall. The Portfolio's net asset
value per share generally moves in the same direction as the market value of the
securities it holds. Therefore, if interest rates rise, you should expect the
Portfolio's net asset value per share to fall, and if interest rates fall, the
Portfolio's net asset value should rise.

Long-term  securities are generally more sensitive to changes in interest rates,
and, therefore,  are subject to a greater degree of market price volatility.  To
the extent the Portfolio holds long-term securities, its net asset value will be
subject to a greater degree of fluctuation than if it held securities of shorter
duration.

Credit risk. A fixed-income security could deteriorate in quality to such an
extent that its rating is downgraded or its market value declines relative to
comparable securities. Credit risk also includes the risk that an issuer of a
debt security would be unable to make interest and principal payments. To the
extent the Portfolio holds securities that have been downgraded, or that default
on payment, its performance could be negatively affected.

While the Portfolio is required to invest a majority of its assets in securities
rated investment-grade on the date of purchase, there is no guarantee that these
securities are free from credit risk. Ratings by Moody's Investors Service and
Standard & Poor's Ratings Services are generally accepted measures of credit
risk. However, these ratings are subject to certain limitations. The rating of
an issuer is based heavily on past developments and does not necessarily reflect
probable future conditions. Ratings also are not updated continuously.

Fixed-income securities, like those in which the Portfolio invests, are traded
principally by dealers in the over-the-counter market. The Portfolio's ability
to sell securities it holds is dependent on the willingness and ability of
market participants to provide bids that reflect current market levels. Adverse
market conditions could reduce the number of ready buyers.


Due to differences of tax treatment and other considerations, there is a
possibility that the interests of various Contract owners who own shares of the
Portfolio may conflict. The Board of Directors monitors events in order to
identify any disadvantages or material irreconcilable conflicts and to determine
what action, if any, should be taken in response.


An investment in the Portfolio 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 information below provides some indication of the risks of investing in the
Portfolio by showing how the performance of Class 1 shares of the Portfolio has
varied year to year, as well as how its performance compares to two widely-used
measures of performance. How the Portfolio has performed in the past, however,
is not necessarily an indication of how it will perform in the future.

Class 1 annual total returns presented in the bar chart and average annual total
returns presented in the table do not reflect the effect of any administration
fees or sales charges imposed by the Contracts on their owners. If these
expenses were included, the returns would be lower. Both the bar chart and table
assume that all dividends and capital gain distributions were reinvested.

Shareholder Information

PRICING OF FUND SHARES

When you buy or sell shares, you do so at the Portfolio's net asset value (NAV)
next calculated after your request is received by participating insurance
companies. If your purchase or sell request is received by participating
insurance companies by the close of regular trading on the New York Stock
Exchange (NYSE) (normally 4:00 p.m. Eastern time), it will be executed at the
Portfolio's NAV calculated as of the close of regular trading on the NYSE on
that day.

If your purchase or sell request is received by participating insurance
companies after the close of regular trading on the NYSE, your request will be
executed at the Portfolio's NAV calculated as of the close of regular trading on
the next NYSE trading day.

The NAV of the Portfolio is computed each day, Monday through Friday, on days
that the NYSE is open for trading. Securities owned by the Portfolio are valued
at current market prices. If reliable market prices are unavailable, securities
are valued in accordance with procedures approved by the Fund's Board of
Directors.


HOW TO PURCHASE AND SELL SHARES

The Portfolio is offering its shares only to Accounts of participating insurance
companies to fund benefits of the Contracts. The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.

An Account may sell all or any portion of the Portfolio shares that it holds at
any time at the next computed NAV per share, as described above. Portfolio
shares that are sold are entitled to any dividends that have been declared as
payable to record owners up to and including the day the sale is effected. There
is no charge. Payment of the sale price will normally be made within seven days
after receipt of such sale. In addition, the right to sell your shares may be
suspended and the date of payment of the sale price may be postponed for any
period during which the NYSE is closed (other than customary weekend and holiday
closings) or during which the Securities and Exchange Commission (SEC)
determines that trading thereon is restricted, or for any period during which an
emergency (as determined by the SEC) exists as a result of which the sale of
Portfolio shares is not reasonably practicable or as a result of which it is not
reasonably practicable for the Portfolio to fairly determine the value of its
net assets, or for such other periods as the SEC may by order permit for the
protection of shareholders.

The Fund and the Portfolio

OVERVIEW OF THE FUND

Seligman Portfolios, Inc. (the Fund) consists of 15 separate portfolios. This
Prospectus contains information about Seligman Bond Portfolio (the Portfolio).


The Portfolio is offering its shares only to separate accounts (Accounts) of
participating insurance companies to fund benefits of variable annuity and
variable life insurance contracts (Contracts). The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.


The Portfolio offers two classes of shares: Class 1 shares and Class 2 shares.
This Prospectus offers only Class 2 shares and is for use with Accounts that
make Class 2 shares available to Contract owners.

INVESTMENT OBJECTIVE

The Portfolio's objective is favorable current income.

PRINCIPAL INVESTMENT STRATEGIES

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

Generally, the Portfolio invests in fixed-income securities, diversified among a
number of market sectors. The Portfolio has a fundamental policy that at least
80% of the Portfolio's assets will be invested in securities that are rated
investment-grade when purchased by the Portfolio. The Portfolio may invest in
securities of any duration. Capital appreciation is a secondary consideration in
selecting securities for purchase by the Portfolio.

The Portfolio may invest in corporate debt securities (including bonds and
debentures convertible into common stock or with rights and warrants),
securities issued or guaranteed by the US Treasury, its agencies or
instrumentalities, mortgage-backed securities (including collateralized mortgage
obligations and mortgage pass-through securities), and high-grade money market
instruments. The Portfolio may also hold or sell any securities obtained through
the exercise of conversion rights or warrants, or as a result of a
reorganization, recapitalization, or liquidation proceeding of any issuer of
securities owned by the Portfolio.

The Portfolio's investment approach combines macro analysis of the fixed-income
market with fundamental research into individual securities, customized by
market sector. This means that the investment manager considers the trends in
the fixed-income market and evaluates the long-term trends in interest rates,
and then selects individual securities for the Portfolio based on its evaluation
of each security's particular characteristics (for example, duration, yield,
quality, relative value). The average maturity of the Portfolio will vary in
response to what the investment manager believes to be the long-term trend in
interest rates. Generally, if rates are trending up, the Portfolio will tend to
hold securities with shorter maturities. If rates are trending down, the
Portfolio will tend to hold securities with longer maturities. Additionally, the
Portfolio's concentration in any particular market sector and the Portfolio's
individual security holdings will vary depending on the investment manager's
view of the relative value offered by certain sectors, as well as specific
securities within those sectors.

In selecting individual securities for purchase by the Portfolio, the investment
manager will seek to identify securities of various market sectors that it
believes offer better total return opportunities.

The Portfolio generally sells securities when the investment manager believes
that the direction of long-term interest rates is changing, better opportunities
exist in the market, or yield spreads (i.e., the yields offered on different
securities) have become too narrow to justify the added volatility of long-term
securities (which generally offer higher yields), or when the Portfolio must
meet cash requirements.

                                      P-1

<PAGE>


The Portfolio may invest up to 15% of its net assets in illiquid securities
(i.e., securities that cannot be readily sold), and may invest up to 10% of its
total assets directly in foreign securities. The Portfolio may purchase
securities on a when-issued or forward commitment basis (delivery of securities
and payment of the purchase price takes place after the commitment to purchase
the securities). The Portfolio generally does not invest a significant amount,
if any, in illiquid or foreign securities.

The Portfolio may change its principal strategies, except for stated fundamental
policies, if the Fund's Board of Directors believes doing so is consistent with
the Portfolio's objective. The Portfolio's objective and any fundamental
policies may be changed only with shareholder approval. If a change of objective
or fundamental policies is proposed, Contract owners will be asked to give
voting instructions to the participating insurance companies.

The Portfolio 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 Portfolio from achieving its objective.

There is no guarantee that the Portfolio will achieve its objective.

PRINCIPAL RISKS

The value of your investment in the Portfolio will fluctuate with fluctuations
in the value of the securities held by the Portfolio. The principal factors that
may affect the value of the Portfolio's securities holdings are changes in
interest rates and the credit worthiness of the issuers of securities held by
the Portfolio.

Interest rate risk. Changes in market interest rates will affect the value of
securities held by the Portfolio. The Portfolio invests mostly in fixed-income
securities. In general, the market value of fixed-income securities moves in the
opposite direction of interest rates: the market value decreases when interest
rates rise and increases when interest rates fall. The Portfolio's net asset
value per share generally moves in the same direction as the market value of the
securities it holds. Therefore, if interest rates rise, you should expect the
Portfolio's net asset value per share to fall, and if interest rates fall, the
Portfolio's net asset value should rise.

Long-term securities are generally more sensitive to changes in interest rates,
and, therefore, are subject to a greater degree of market price volatility. To
the extent the Portfolio holds long-term securities, its net asset value will be
subject to a greater degree of fluctuation than if it held securities of shorter
duration.

Credit risk. A fixed-income security could deteriorate in quality to such an
extent that its rating is downgraded or its market value declines relative to
comparable securities. Credit risk also includes the risk that an issuer of a
debt security would be unable to make interest and principal payments. To the
extent the Portfolio holds securities that have been downgraded, or that default
on payment, its performance could be negatively affected.

While the Portfolio is required to invest a majority of its assets in securities
rated investment-grade on the date of purchase, there is no guarantee that these
securities are free from credit risk. Ratings by Moody's Investors Service and
Standard & Poor's Ratings Services are generally accepted measures of credit
risk. However, these ratings are subject to certain limitations. The rating of
an issuer is based heavily on past developments and does not necessarily reflect
probable future conditions. Ratings also are not updated continuously.

Fixed-income securities, like those in which the Portfolio invests, are traded
principally by dealers in the over-the-counter market. The Portfolio's ability
to sell securities it holds is dependent on the willingness and ability of
market participants to provide bids that reflect current market levels. Adverse
market conditions could reduce the number of ready buyers.


Due to differences of tax treatment and other considerations, there is a
possibility that the interests of various Contract owners who own shares of the
Portfolio may conflict. The Board of Directors monitors events in order to
identify any disadvantages or material irreconcilable conflicts and to determine
what action, if any, should be taken in response.


An investment in the Portfolio 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

Class 2 shares are newly offered and have no performance history. The
information below provides some indication of the risks of investing in the
Portfolio by showing how the performance of Class 1 shares of the Portfolio has
varied year to year, as well as how its performance compares to two widely-used
measures of performance. How the Portfolio has performed in the past, however,
is not necessarily an indication of how it will perform in the future.


Total returns will vary between Class 1 shares and Class 2 shares due to
different expenses of the two Classes. Class 1 annual total returns presented in
the bar chart and average annual total returns presented in the table do not
reflect the effect of the shareholder servicing and distribution (12b-1) fees
associated with Class 2 shares or the effect of any administration fees or sales
charges imposed by the Contracts on their owners. If these expenses were
included, the returns would be lower. Both the bar chart and table assume that
all dividends and capital gain distributions were reinvested.

The NAV of the Portfolio is computed each day, Monday through Friday, on days
that the NYSE is open for trading. Securities owned by the Portfolio are valued
at current market prices. If reliable market prices are unavailable, securities
are valued in accordance with procedures approved by the Fund's Board of
Directors.

HOW TO PURCHASE AND SELL SHARES

The Portfolio is offering its shares only to Accounts of participating insurance
companies to fund benefits of the Contracts. The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.

An Account may sell all or any portion of the Portfolio shares that it holds at
any time at the next computed NAV per share, as described above. Portfolio
shares that are sold are entitled to any dividends that have been declared as
payable to record owners up to and including the day the sale is effected. There
is no charge. Payment of the sale price will normally be made within seven days
after receipt of such sale. In addition, the right to sell your shares may be
suspended and the date of payment of the sale price may be postponed for any
period during which the NYSE is closed (other than customary weekend and holiday
closings) or during which the Securities and Exchange Commission (SEC)
determines that trading thereon is restricted, or for any period during which an
emergency (as determined by the SEC) exists as a result of which the sale of
Portfolio shares is not reasonably practicable or as a result of which it is not
reasonably practicable for the Portfolio to fairly determine the value of its
net assets, or for such other periods as the SEC may by order permit for the
protection of shareholders.


SHAREHOLDER SERVICING AND DISTRIBUTION ARRANGEMENTS

Under a Rule 12b-1 plan adopted by the Fund with respect to the Portfolio, Class
2 shares pay an annual shareholder servicing and distribution (12b-1) fee of up
to 0.25% of average net assets. The Portfolio pays this fee to Seligman
Advisors, Inc., the principal underwriter of the Portfolio's shares. Seligman
Advisors uses this fee to make payments to participating insurance companies or
their affiliates for services that the participating insurance companies provide
to Contract owners of Class 2 shares, and for distribution related expenses.
Because these 12b-1 fees are paid out of the Portfolio's assets on an ongoing
basis, over time they will increase the cost of a Contract owner's investment
and may cost you more than other types of sales charges.



                                      P-5

<PAGE>


DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS

Dividends and capital gain distributions from the Portfolio will be declared and
paid annually and will be reinvested in additional shares, at NAV, of the
Portfolio. Dividends on Class 2 shares generally will be lower than the
dividends on Class 1 shares as a result of 12b-1 fees. Capital gain
distributions will be paid in the same amount for each Class.

TAXES

Further information regarding the tax consequences of an investment in the
Portfolio is contained in the separate prospectuses and disclosure documents
issued by the participating insurance companies and accompanying this
Prospectus.

Financial Highlights


The table below describes the Portfolio's performance for the past five years.
It is intended to help you understand the financial performance of the
Portfolio's Class 1 shares. Class 2 shares are a newly offered Class, effective
May 1, 2000, so financial highlights are not available. Certain information
reflects financial results for a single share of the Portfolio that was held
throughout the periods shown. "Total return" shows the rate that you would have
earned (or lost) on an investment in the Portfolio. Total returns do not reflect
the effect of the shareholder servicing and distribution (12b-1) fees associated
with Class 2 shares or any administration fees or sales charges imposed by the
Contracts on their owners. Ernst & Young LLP, independent auditors, have audited
this information. Their report, along with the Portfolio's financial statements,
is included in the Fund's annual report, which is available upon request.

The Fund and the Portfolio

OVERVIEW OF THE FUND

Seligman Portfolios, Inc. (the Fund) consists of 15 separate portfolios. This
Prospectus contains information about Seligman Capital Portfolio (the
Portfolio).


The Portfolio is offering its shares only to separate accounts (Accounts) of
participating insurance companies to fund benefits of variable annuity and
variable life insurance contracts (Contracts). The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.


The Portfolio offers two classes of shares: Class 1 shares and Class 2 shares.
This Prospectus offers only Class 1 shares and is for use with Accounts that
make Class 1 shares available to Contract owners.

INVESTMENT OBJECTIVE

The Portfolio's objective is capital appreciation.

PRINCIPAL INVESTMENT STRATEGIES

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

Generally, the Portfolio invests primarily in the common stock of medium-sized
US companies. The investment manager chooses common stocks for the Portfolio
using both quantitative and fundamental analysis. This means the investment
manager first screens companies for past growth in sales and earnings, as well
as a strong balance sheet (e.g., low ratio of debt to total capital). In
selecting individual securities for investment, the investment manager then
looks to identify medium-sized companies that it believes display one or more of
the following:

- --------------------------
Medium-Sized Companies:

Companies with market
capitalizations, at the
time of purchase by the
Portfolio, of between
$1 billion and $10 billion.
- --------------------------

o    Proven track record

o    Strong management

o    Multiple product lines

o    Potential for improvement in overall operations (a catalyst for growth in
     revenues and/or earnings)

o    Positive supply and demand outlook for its industry

The investment manager also looks at the forecasted earnings of a company
considered for investment to determine if the company has the potential for
above-average growth.

The Portfolio will generally sell a stock when the investment manager believes
that the company or industry fundamentals have deteriorated or the company's
catalyst for growth is already reflected in the stock's price (i.e., the stock
is fully valued).

The Portfolio primarily invests in common stocks. However, the Portfolio may
also invest in preferred stocks, securities convertible into common stocks,
common stock rights or warrants, and debt securities if the investment manager
believes they offer capital appreciation opportunities.


                                       P-1


<PAGE>



The Portfolio may invest up to 15% of its net assets in illiquid securities
(i.e., securities that cannot be readily sold) and may invest up to 10% of its
total assets directly in foreign securities. The Portfolio generally does not
invest a significant amount, if any, in illiquid or foreign securities. The
Portfolio may borrow money from time to time to purchase securities.

The Portfolio may change its principal strategies, except for stated fundamental
policies, if the Fund's Board of Directors believes doing so is consistent with
the Portfolio's objective. The Portfolio's objective and any fundamental
policies may be changed only with shareholder approval. If a change of objective
or fundamental policies is proposed, Contract owners will be asked to give
voting instructions to the participating insurance companies.

The Portfolio 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 Portfolio from achieving its objective.

The Fund's Board of Directors may change the parameters by which "medium-sized
companies" are defined if it concludes that such a change is appropriate.


There is no guarantee that the Portfolio will achieve its objective.

PRINCIPAL RISKS

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

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

The Portfolio may not invest more than 25% of its total assets in securities of
companies in any one industry. The Portfolio may, however, invest more heavily
in certain industries which the investment manager believes offer good
investment opportunities. If an industry in which the Portfolio is invested
falls out of favor, the Portfolio's performance may be negatively affected.


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


The Portfolio 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 Portfolio's expenses.


Due to differences of tax treatment and other considerations, there is a
possibility that the interests of various Contract owners who own shares of the
Portfolio may conflict. The Board of Directors monitors events in order to
identify any disadvantages or material irreconcilable conflicts and to determine
what action, if any, should be taken in response.


An investment in the Portfolio 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 information below provides some indication of the risks of investing in the
Portfolio by showing how the performance of Class 1 shares of the Portfolio has
varied year to year, as well as how its performance compares to two widely-used
measures of performance. How the Portfolio has performed in the past, however,
is not necessarily an indication of how it will perform in the future.

Class 1 annual total returns presented in the bar chart and average annual total
returns presented in the table do not reflect the effect of any administration
fees or sales charges imposed by the Contracts on their owners. If these
expenses were included, the returns would be lower. Both the bar chart and table
assume that all dividends and capital gain distributions were reinvested.

Shareholder Information

PRICING OF FUND SHARES

When you buy or sell shares, you do so at the Portfolio's net asset value (NAV)
next calculated after your request is received by participating insurance
companies. If your purchase or sell request is received by participating
insurance companies by the close of regular trading on the New York Stock
Exchange (NYSE) (normally 4:00 p.m. Eastern time), it will be executed at the
Portfolio's NAV calculated as of the close of regular trading on the NYSE on
that day.

If your purchase or sell request is received by participating insurance
companies after the close of regular trading on the NYSE, your request will be
executed at the Portfolio's NAV calculated as of the close of regular trading on
the next NYSE trading day.

The NAV of the Portfolio is computed each day, Monday through Friday, on days
that the NYSE is open for trading. Securities owned by the Portfolio are valued
at current market prices. If reliable market prices are unavailable, securities
are valued in accordance with procedures approved by the Fund's Board of
Directors.

HOW TO PURCHASE AND SELL SHARES

The Portfolio is offering its shares only to Accounts of participating insurance
companies to fund benefits of the Contracts. The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.

An Account may sell all or any portion of the Portfolio shares that it holds at
any time at the next computed NAV per share, as described above. Portfolio
shares that are sold are entitled to any dividends that have been declared as
payable to record owners up to and including the day the sale is effected. There
is no charge. Payment of the sale price will normally be made within seven days
after receipt of such sale. In addition, the right to sell your shares may be
suspended and the date of payment of the sale price may be postponed for any
period during which the NYSE is closed (other than customary weekend and holiday
closings) or during which the Securities and Exchange Commission (SEC)
determines that trading thereon is restricted, or for any period during which an
emergency (as determined by the SEC) exists as a result of which the sale of
Portfolio shares is not reasonably practicable or as a result of which it is not
reasonably practicable for the Portfolio to fairly determine the value of its
net assets, or for such other periods as the SEC may by order permit for the
protection of shareholders.

Financial Highlights

The table below describes the Portfolio's performance for the past five years.

The Fund and the Portfolio

OVERVIEW OF THE FUND

Seligman Portfolios, Inc. (the Fund) consists of 15 separate portfolios. This
Prospectus contains information about Seligman Capital Portfolio (the
Portfolio).


The Portfolio is offering its shares only to separate accounts (Accounts) of
participating insurance companies to fund benefits of variable annuity and
variable life insurance contracts (Contracts). The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.


The Portfolio offers two classes of shares: Class 1 shares and Class 2 shares.
This Prospectus offers only Class 2 shares and is for use with Accounts that
make Class 2 shares available to Contract owners.

INVESTMENT OBJECTIVE

The Portfolio's objective is capital appreciation.

PRINCIPAL INVESTMENT STRATEGIES

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

Generally, the Portfolio invests primarily in the common stock of medium-sized
US companies. The investment manager chooses common stocks for the Portfolio
using both quantitative and fundamental analysis. This means the investment
manager first screens companies for past growth in sales and earnings, as well
as a strong balance sheet (e.g., low ratio of debt to total capital). In
selecting individual securities for investment, the investment manager then
looks to identify medium-sized companies that it believes display one or more of
the following:

- --------------------------
Medium-Sized Companies:

Companies with market
capitalizations, at the
time of purchase by the
Portfolio, of between
$1 billion and $10 billion.
- --------------------------

o    Proven track record

o    Strong management

o    Multiple product lines

o    Potential for improvement in overall operations (a catalyst for growth in
     revenues and/or earnings)

o    Positive supply and demand outlook for its industry

The investment manager also looks at the forecasted earnings of a company
considered for investment to determine if the company has the potential for
above-average growth.

The Portfolio will generally sell a stock when the investment manager believes
that the company or industry fundamentals have deteriorated or the company's
catalyst for growth is already reflected in the stock's price (i.e., the stock
is fully valued).

The Portfolio primarily invests in common stocks. However, the Portfolio may
also invest in preferred stocks, securities convertible into common stocks,
common stock rights or warrants, and debt securities if the investment manager
believes they offer capital appreciation opportunities.

                                      P-1

<PAGE>


The Portfolio may invest up to 15% of its net assets in illiquid securities
(i.e., securities that cannot be readily sold) and may invest up to 10% of its
total assets directly in foreign securities. The Portfolio generally does not
invest a significant amount, if any, in illiquid or foreign securities. The
Portfolio may borrow money from time to time to purchase securities.


The Portfolio may change its principal strategies, except for stated fundamental
policies, if the Fund's Board of Directors believes doing so is consistent with
the Portfolio's objective. The Portfolio's objective and any fundamental
policies may be changed only with shareholder approval. If a change of objective
or fundamental policies is proposed, Contract owners will be asked to give
voting instructions to the participating insurance companies.

The Portfolio 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 Portfolio from achieving its objective.

The Fund's Board of Directors may change the parameters by which "medium-sized
companies" are defined if it concludes that such a change is appropriate.


There is no guarantee that the Portfolio will achieve its investment objective.

PRINCIPAL RISKS

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

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

The Portfolio may not invest more than 25% of its total assets in securities of
companies in any one industry. The Portfolio may, however, invest more heavily
in certain industries which the investment manager believes offer good
investment opportunities. If an industry in which the Portfolio is invested
falls out of favor, the Portfolio's performance may be negatively affected.


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

The Portfolio 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 Portfolio's expenses.

Due to differences of tax treatment and other considerations, there is a
possibility that the interests of various Contract owners who own shares of the
Portfolio may conflict. The Board of Directors monitors events in order to
identify any disadvantages or material irreconcilable conflicts and to determine
what action, if any, should be taken in response.


An investment in the Portfolio 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

Class 2 shares are newly offered and have no performance history. The
information below provides some indication of the risks of investing in the
Portfolio by showing how the performance of Class 1 shares of the Portfolio has
varied year to year, as well as how its performance compares to two widely-used
measures of performance. How the Portfolio has performed in the past, however,
is not necessarily an indication of how it will perform in the future.


Total returns will vary between Class 1 shares and Class 2 shares due to
different expenses of the two Classes. Class 1 annual total returns presented in
the bar chart and average annual total returns presented in the table do not
reflect the effect of the shareholder servicing and distribution (12b-1) fees
associated with Class 2 shares or the effect of any administration fees or sales
charges imposed by the Contracts on their owners. If these expenses were
included, the returns would be lower. Both the bar chart and table assume that
all dividends and capital gain distributions were reinvested.

Shareholder Information

PRICING OF FUND SHARES

When you buy or sell shares, you do so at the Portfolio's net asset value (NAV)
next calculated after your request is received by participating insurance
companies. If your purchase or sell request is received by participating
insurance companies by the close of regular trading on the New York Stock
Exchange (NYSE) (normally 4:00 p.m. Eastern time), it will be executed at the
Portfolio's NAV calculated as of the close of regular trading on the NYSE on
that day.

If your purchase or sell request is received by participating insurance
companies after the close of regular trading on the NYSE, your request will be
executed at the Portfolio's NAV calculated as of the close of regular trading on
the next NYSE trading day.

The NAV of the Portfolio is computed each day, Monday through Friday, on days
that the NYSE is open for trading. Securities owned by the Portfolio are valued
at current market prices. If reliable market prices are unavailable, securities
are valued in accordance with procedures approved by the Fund's Board of
Directors.

HOW TO PURCHASE AND SELL SHARES

The Portfolio is offering its shares only to Accounts of participating insurance
companies to fund benefits of the Contracts. The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.

An Account may sell all or any portion of the Portfolio shares that it holds at
any time at the next computed NAV per share, as described above. Portfolio
shares that are sold are entitled to any dividends that have been declared as
payable to record owners up to and including the day the sale is effected. There
is no charge. Payment of the sale price will normally be made within seven days
after receipt of such sale. In addition, the right to sell your shares may be
suspended and the date of payment of the sale price may be postponed for any
period during which the NYSE is closed (other than customary weekend and holiday
closings) or during which the Securities and Exchange Commission (SEC)
determines that trading thereon is restricted, or for any period during which an
emergency (as determined by the SEC) exists as a result of which the sale of
Portfolio shares is not reasonably practicable or as a result of which it is not
reasonably practicable for the Portfolio to fairly determine the value of its
net assets, or for such other periods as the SEC may by order permit for the
protection of shareholders.


SHAREHOLDER SERVICING AND DISTRIBUTION ARRANGEMENTS

Under a Rule 12b-1 plan adopted by the Fund with respect to the Portfolio, Class
2 shares pay an annual shareholder servicing and distribution (12b-1) fee of up
to 0.25% of average net assets. The Portfolio pays this fee to Seligman
Advisors, Inc., the principal underwriter of the Portfolio's shares. Seligman
Advisors uses this fee to make payments to participating insurance companies or
their affiliates for services that the participating insurance companies provide
to Contract owners of Class 2 shares, and for distribution related expenses.
Because these 12b-1 fees are paid out of the Portfolio's assets on an ongoing
basis, over time they will increase the cost of a Contract owner's investment
and may cost you more than other types of sales charges.



                                      P-5

<PAGE>


DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS

Dividends and capital gain distributions from the Portfolio will be declared and
paid annually and will be reinvested in additional shares, at NAV, of the
Portfolio. Dividends on Class 2 shares generally will be lower than the
dividends on Class 1 shares as a result of 12b-1 fees. Capital gain
distributions will be paid in the same amount for each Class.

TAXES

Further information regarding the tax consequences of an investment in the
Portfolio is contained in the separate prospectuses and disclosure documents
issued by the participating insurance companies and accompanying this
Prospectus.

Financial Highlights


The table below describes the Portfolio's performance for the past five years.
It is intended to help you understand the financial performance of the
Portfolio's Class 1 shares. Class 2 shares are a newly offered Class, effective
May 1, 2000, so financial highlights are not available. Certain information
reflects financial results for a single share of the Portfolio that was held
throughout the periods shown. "Total return" shows the rate that you would have
earned (or lost) on an investment in the Portfolio. Total returns do not reflect
the effect of the shareholder servicing and distribution (12b-1) fees associated
with Class 2 shares or any administration fees or sales charges imposed by the
Contracts on their owners. Ernst & Young LLP, independent auditors, have audited
this information. Their report, along with the Portfolio's financial statements,
is included in the Fund's annual report, which is available upon request.

The Fund and the Portfolio

OVERVIEW OF THE FUND

Seligman Portfolios, Inc. (the Fund) consists of 15 separate portfolios. This
Prospectus contains information about Seligman Cash Management Portfolio (the
Portfolio).


The Portfolio is offering its shares only to separate accounts (Accounts) of
participating insurance companies to fund benefits of variable annuity and
variable life insurance contracts (Contracts). The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.


The Portfolio offers two classes of shares: Class 1 shares and Class 2 shares.
This Prospectus offers only Class 1 shares and is for use with Accounts that
make Class 1 shares available to Contract owners.

INVESTMENT OBJECTIVES

The Portfolio's objectives are to preserve capital and to maximize liquidity and
current income.

PRINCIPAL INVESTMENT STRATEGIES

The Portfolio uses the following principal strategies to seek its objectives:


The Portfolio invests in US dollar-denominated high-quality money market
instruments. Such instruments include obligations of the US Treasury, its
agencies or instrumentalities, obligations of domestic and foreign banks (such
as certificates of deposit and fixed time deposits), commercial paper and
short-term corporate debt securities, and repurchase agreements with respect to
these types of instruments.


The Portfolio will invest only in US dollar-denominated securities having a
remaining maturity of 13 months (397) days or less and will maintain a US
dollar-weighted average portfolio maturity of 90 days or less.

In seeking to maintain a constant net asset value of $1.00, the Portfolio will
limit its investments to securities that, in accordance with guidelines approved
by the Fund's Board of Directors, present minimal credit risk. Accordingly, the
Portfolio will only purchase US Government securities or securities rated in one
of the two highest rating categories assigned to short-term debt securities by
at least two nationally recognized statistical rating organizations (such as
Moody's Investors Service (Moody's) or Standard & Poor's Ratings Services (S&P),
or if not so rated, determined to be of comparable quality).


Determination of quality is made at the time of investment, in accordance with
procedures approved by the Fund's Board of Directors. The investment manager
continuously monitors the quality of the Portfolio's investments. If the quality
of an investment declines, the Portfolio may, in certain limited circumstances,
continue to hold it.


Currently, the Portfolio invests only in US Government securities and in
securities that are rated in the top category by Moody's and S&P. However, the
Portfolio is permitted to invest up to 5% of its assets in securities rated in
the second rating category by two rating organizations. The Fund may not invest
more than the greater of 1% of its total assets or $1,000,000 in any one
security in the second rating category.


The Portfolio may change its principal strategies, except for stated fundamental
policies, if the Fund's Board of Directors believes doing so is consistent with
the Portfolio's objectives. The Portfolio's objectives and any fundamental
policies may be changed only with shareholder approval. If a change of objective
or fundamental policies is proposed, Contract owners will be asked to give
voting instructions to the participating insurance companies.

There is no guarantee that the Portfolio will achieve its objectives.


                                      P-1

PRINCIPAL RISKS

An investment in the Portfolio is not a deposit in a bank and is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other government
agency. Although the Portfolio seeks to preserve the value of your investment at
$1.00 per share, it is possible to lose money by investing in the Portfolio.


Yield and total return of the Portfolio will fluctuate with fluctuations in the
yields of the securities held by the Portfolio. In periods of declining interest
rates, the yields of the securities held by the Portfolio will tend to be
somewhat higher than prevailing market rates, and in periods of rising interest
rates, the yields of securities held by the Portfolio will tend to be lower than
market rates. Additionally, when interest rates are falling, the inflow of new
money to the Portfolio from sales of its shares will likely be invested in
securities producing lower yields than the balance of the Portfolio's assets,
reducing the current yield of the Portfolio. In periods of rising interest
rates, the opposite may be true.

Repurchase agreements in which the Portfolio invests could involve certain risks
in the event of the default by the seller, including possible delays and
expenses in liquidating the securities underlying the agreement, decline in the
value of the underlying securities and loss of interest.

Investments in foreign banks and foreign branches of US banks involve certain
risks not generally associated with investments in USbanks. While US banks and
US branches of foreign banks are required to maintain certain reserve and are
subject to other regulations, these requirements and regulations may not apply
to foreign banks or foreign branches of US banks. Investments in foreign banks
or foreign branches may also be subject to other risks, including political or
economic developments, the seizure or nationalization of foreign deposits and
the establishments of exchange controls or other restrictions.


Due to differences of tax treatment and other considerations, there is a
possibility that the interests of various Contract owners who own shares of the
Portfolio may conflict. The Board of Directors monitors events in order to
identify any disadvantages or material irreconcilable conflicts and to determine
what action, if any, should be taken in response.

PAST PERFORMANCE

The information below provides some indication of the risks of investing in the
Portfolio by showing how the performance of Class 1 shares of the Portfolio has
varied year to year. How the Portfolio has performed in the past, however, is
not necessarily an indication of how it will perform in the future.


Class 1 annual total returns presented in the bar chart and average annual total
returns presented in the table do not reflect the effect of any administration
fees or sales charges imposed by the Contracts on their owners. If these
expenses were included, the returns would be lower. Both the bar chart and table
assume that all dividends were reinvested.

MANAGEMENT OF THE FUND

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


J. & W. Seligman & Co. Incorporated (Seligman), 100 Park Avenue, New York, New
York 10017, is the manager of the Fund. Seligman provides investment management
services for the Portfolio, including making purchases and sales of securities
for the Portfolio, consistent with the Portfolio's investment objectives and
strategies, and administers the Portfolio's business and other affairs.

Established in 1864, Seligman currently serves as manager to 20 US registered
investment companies, which offer more than 50 investment portfolios with
approximately $30 billion in assets as of March 31, 2000. Seligman also provides
investment management or advice to institutional or other accounts having an
aggregate value at March 31, 2000 of approximately $12 billion.

The Portfolio pays Seligman a management fee for its services, equal to an
annual rate of .40% of the average daily net assets of the Portfolio. For the
period ended December 31, 1999, Seligman voluntarily waived its management fee
for the Portfolio. There is no assurance that Seligman will continue this policy
in the future.

Shareholder Information

PRICING OF FUND SHARES

When you buy or sell shares, you do so at the Portfolio's net asset value (NAV)
next calculated after your request is received by participating insurance
companies. If your purchase or sell request is received by participating
insurance companies by the close of regular trading on the New York Stock
Exchange (NYSE) (normally 4:00 p.m. Eastern time), it will be executed at the
Portfolio's NAV calculated as of the close of regular trading on the NYSE on
that day.

If your purchase or sell request is received by participating insurance
companies after the close of regular trading on the NYSE, your request will be
executed at the Portfolio's NAV calculated as of the close of regular trading on
the next NYSE trading day.

The NAV of the Portfolio is computed each day, Monday through Friday, on days
that the NYSE is open for trading. Securities owned by the Portfolio are valued
at current market prices. If reliable market prices are unavailable, securities
are valued in accordance with procedures approved by the Fund's Board of
Directors.

HOW TO PURCHASE AND SELL SHARES

The Portfolio is offering its shares only to Accounts of participating insurance
companies to fund benefits of the Contracts. The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.

An Account may sell all or any portion of the Portfolio shares that it holds at
any time at the next computed NAV per share, as described above. Portfolio
shares that are sold are entitled to any dividends that have been declared as
payable to record owners up to and including the day the sale is effected. There
is no charge. Payment of the sale price will normally be made within seven days
after receipt of such sale. In addition, the right to sell your shares may be
suspended and the date of payment of the sale price may be postponed for any
period during which the NYSE is closed (other than customary weekend and holiday
closings) or during which the Securities and Exchange Commission (SEC)
determines that trading thereon is restricted, or for any period during which an
emergency (as determined by the SEC) exists as a result of which the sale of
Portfolio shares is not reasonably practicable or as a result of which it is not
reasonably practicable for the Portfolio to fairly determine the value of its
net assets, or for such other periods as the SEC may by order permit for the
protection of shareholders.

DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS


Dividends from the Portfolio will be declared daily and reinvested monthly in
additional shares, at NAV, of the Portfolio. It is not expected that the
Portfolio will realize capital gains.


TAXES

Further information regarding the tax consequences of an investment in the
Portfolio is contained in the separate prospectuses and disclosure documents
issued by the participating insurance companies and accompanying this
Prospectus.

The Fund and the Portfolio

OVERVIEW OF THE FUND

Seligman Portfolios, Inc. (the Fund) consists of 15 separate portfolios. This
Prospectus contains information about Seligman Cash Management Portfolio (the
Portfolio).


The Portfolio is offering its shares only to separate accounts (Accounts) of
participating insurance companies to fund benefits of variable annuity and
variable life insurance contracts (Contracts). The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.


The Portfolio offers two classes of shares: Class 1 shares and Class 2 shares.
This Prospectus offers only Class 2 shares and is for use with Accounts that
make Class 2 shares available to Contract owners.

INVESTMENT OBJECTIVES

The Portfolio's objectives are to preserve capital and to maximize liquidity and
current income.

PRINCIPAL INVESTMENT STRATEGIES

The Portfolio uses the following principal strategies to seek its objectives:


The Portfolio invests in US dollar-denominated high-quality money market
instruments. Such instruments include obligations of the US Treasury, its
agencies or instrumentalities, obligations of domestic and foreign banks (such
as certificates of deposit and fixed time deposits), commercial paper and
short-term corporate debt securities, and repurchase agreements with respect to
these types of instruments.


The Portfolio will invest only in US dollar-denominated securities having a
remaining maturity of 13 months (397) days or less and will maintain a US
dollar-weighted average portfolio maturity of 90 days or less.

In seeking to maintain a constant net asset value of $1.00, the Portfolio will
limit its investments to securities that, in accordance with guidelines approved
by the Fund's Board of Directors, present minimal credit risk. Accordingly, the
Portfolio will only purchase US Government securities or securities rated in one
of the two highest rating categories assigned to short-term debt securities by
at least two nationally recognized statistical rating organizations (such as
Moody's Investors Service (Moody's) or Standard & Poor's Ratings Services (S&P),
or if not so rated, determined to be of comparable quality).


Determination of quality is made at the time of investment, in accordance with
procedures approved by the Fund's Board of Directors. The investment manager
continuously monitors the quality of the Portfolio's investments. If the quality
of an investment declines, the Portfolio may, in certain limited circumstances,
continue to hold it.


Currently, the Portfolio invests only in US Government securities and in
securities that are rated in the top category by Moody's and S&P. However, the
Portfolio is permitted to invest up to 5% of its assets in securities rated in
the second rating category by two rating organizations. The Fund may not invest
more than the greater of 1% of its total assets or $1,000,000 in any one
security in the second rating category.


The Portfolio may change its principal strategies, except for stated fundamental
policies, if the Fund's Board of Directors believes doing so is consistent with
the Portfolio's objective. The Portfolio's objective and any fundamental
policies may be changed only with shareholder approval. If a change of objective
or fundamental policies is proposed, Contract owners will be asked to give
voting instructions to the participating insurance companies.


There is no guarantee that the Portfolio will achieve its objectives.


                                      P-1

PRINCIPAL RISKS


An investment in the Portfolio is not a deposit in a bank and is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other government
agency. Although the Portfolio seeks to preserve the value of your investment at
$1.00 per share, it is possible to lose money by investing in the Portfolio.


Yield and total return of the Portfolio will fluctuate with fluctuations in the
yields of the securities held by the Portfolio. In periods of declining interest
rates, the yields of the securities held by the Portfolio will tend to be
somewhat higher than prevailing market rates, and in periods of rising interest
rates, the yields of securities held by the Portfolio will tend to be lower than
market rates. Additionally, when interest rates are falling, the inflow of new
money to the Portfolio from sales of its shares will likely be invested in
securities producing lower yields than the balance of the Portfolio's assets,
reducing the current yield of the Portfolio. In periods of rising interest
rates, the opposite may be true.

Repurchase agreements in which the Portfolio invests could involve certain risks
in the event of the default by the seller, including possible delays and
expenses in liquidating the securities underlying the agreement, decline in the
value of the underlying securities and loss of interest.

Investments in foreign banks and foreign branches of US banks involve certain
risks not generally associated with investments in US banks. While US banks and
US branches of foreign banks are required to maintain certain reserve and are
subject to other regulations, these requirements and regulations may not apply
to foreign banks or foreign branches of US banks. Investments in foreign banks
or foreign branches may also be subject to other risks, including political or
economic developments, the seizure or nationalization of foreign deposits and
the establishments of exchange controls or other restrictions.


Due to differences of tax treatment and other considerations, there is a
possibility that the interests of various Contract owners who own shares of the
Portfolio may conflict. The Board of Directors monitors events in order to
identify any disadvantages or material irreconcilable conflicts and to determine
what action, if any, should be taken in response.

PAST PERFORMANCE

Class 2 shares are newly offered and have no performance history. The
information below provides some indication of the risks of investing in the
Portfolio by showing how the performance of Class 1 shares of the Portfolio has
varied year to year. How the Portfolio has performed in the past, however, is
not necessarily an indication of how it will perform in the future.


Total returns will vary between Class 1 shares and Class 2 shares due to
different expenses of the two Classes. Class 1 annual total returns presented in
the bar chart and average annual total returns presented in the table do not
reflect the effect of the shareholder servicing and distribution (12b-1) fees
associated with Class 2 shares or the effect of any administration fees or sales
charges imposed by the Contracts on their owners. If these expenses were
included, the returns would be lower. Both the bar chart and table assume that
all dividends were reinvested.

MANAGEMENT OF THE FUND

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


J. & W. Seligman & Co. Incorporated (Seligman), 100 Park Avenue, New York, New
York 10017, is the manager of the Fund. Seligman provides investment management
services for the Portfolio, including making purchases and sales of securities
for the Portfolio, consistent with the Portfolio's investment objectives and
strategies, and administers the Portfolio's business and other affairs.

Established in 1864, Seligman currently serves as manager to 20 US registered
investment companies, which offer more than 50 investment portfolios with
approximately $30 billion in assets as of March 31, 2000. Seligman also provides
investment management or advice to institutional or other accounts having an
aggregate value at March 31, 2000 of approximately $12 billion.

The Portfolio pays Seligman a management fee for its services, equal to an
annual rate of .40% of the average daily net assets of the Portfolio. For the
period ended December 31, 1999, Seligman voluntarily waived its management fee
for the Portfolio. There is no assurance that Seligman will continue this policy
in the future.

Shareholder Information

PRICING OF FUND SHARES

When you buy or sell shares, you do so at the Portfolio's net asset value (NAV)
next calculated after your request is received by participating insurance
companies. If your purchase or sell request is received by participating
insurance companies by the close of regular trading on the New York Stock
Exchange (NYSE) (normally 4:00 p.m. Eastern time), it will be executed at the
Portfolio's NAV calculated as of the close of regular trading on the NYSE on
that day.

If your purchase or sell request is received by participating insurance
companies after the close of regular trading on the NYSE, your request will be
executed at the Portfolio's NAV calculated as of the close of regular trading on
the next NYSE trading day.

The NAV of the Portfolio is computed each day, Monday through Friday, on days
that the NYSE is open for trading. Securities owned by the Portfolio are valued
at current market prices. If reliable market prices are unavailable, securities
are valued in accordance with procedures approved by the Fund's Board of
Directors.

HOW TO PURCHASE AND SELL SHARES

The Portfolio is offering its shares only to Accounts of participating insurance
companies to fund benefits of the Contracts. The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.

An Account may sell all or any portion of the Portfolio shares that it holds at
any time at the next computed NAV per share, as described above. Portfolio
shares that are sold are entitled to any dividends that have been declared as
payable to record owners up to and including the day the sale is effected. There
is no charge. Payment of the sale price will normally be made within seven days
after receipt of such sale. In addition, the right to sell your shares may be
suspended and the date of payment of the sale price may be postponed for any
period during which the NYSE is closed (other than customary weekend and holiday
closings) or during which the Securities and Exchange Commission (SEC)
determines that trading thereon is restricted, or for any period during which an
emergency (as determined by the SEC) exists as a result of which the sale of
Portfolio shares is not reasonably practicable or as a result of which it is not
reasonably practicable for the Portfolio to fairly determine the value of its
net assets, or for such other periods as the SEC may by order permit for the
protection of shareholders.


SHAREHOLDER SERVICING AND DISTRIBUTION ARRANGEMENTS

Under a Rule 12b-1 plan adopted by the Fund with respect to the Portfolio, Class
2 shares pay an annual shareholder servicing and distribution (12b-1) fee of up
to 0.25% of average net assets. The Portfolio pays this fee to Seligman
Advisors, Inc., the principal underwriter of the Portfolio's shares. Seligman
Advisors uses this fee to make payments to participating insurance companies or
their affiliates for services that the participating insurance companies provide
to Contract owners of Class 2 shares, and for distribution related expenses.
Because these 12b-1 fees are paid out of the Portfolio's assets on an ongoing
basis, over time they will increase the cost of a Contract owner's investment
and may cost you more than other types of sales charges.



                                      P-5

<PAGE>


DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS


Dividends from the Portfolio will be declared daily and reinvested monthly in
additional shares, at NAV, of the Portfolio. Dividends on Class 2 shares
generally will be lower than the dividends on Class 1 shares as a result of
12b-1 fees. It is not expected that the Portfolio will realize capital gains.


TAXES

Further information regarding the tax consequences of an investment in the
Portfolio is contained in the separate prospectuses and disclosure documents
issued by the participating insurance companies and accompanying this
Prospectus.

Financial Highlights


The table below describes the Portfolio's performance for the past five years.
It is intended to help you understand the financial performance of the
Portfolio's Class 1 shares. Class 2 shares are a newly offered Class, effective
May 1, 2000, so financial highlights are not available. Certain information
reflects financial results for a single share of the Portfolio that was held
throughout the periods shown. "Total return" shows the rate that you would have
earned (or lost) on an investment in the Portfolio. Total returns do not reflect
the effect of the shareholder servicing and distribution (12b-1) fees associated
with Class 2 shares or any administration fees or sales charges imposed by the
Contracts on their owners. Ernst & Young llp, independent auditors, have audited
this information. Their report, along with the Portfolio's financial statements,
is included in the Fund's annual report, which is available upon request.

The Fund and the Portfolio

OVERVIEW OF THE FUND

Seligman Portfolios, Inc. (the Fund) consists of 15 separate portfolios. This
Prospectus contains information about Seligman Communications and Information
Portfolio (the Portfolio).


The Portfolio is offering its shares only to separate accounts (Accounts) of
participating insurance companies to fund benefits of variable annuity and
variable life insurance contracts (Contracts). The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.


The Portfolio offers two classes of shares: Class 1 shares and Class 2 shares.
This Prospectus offers only Class 1 shares and is for use with Accounts that
make Class 1 shares available to Contract owners.


INVESTMENT OBJECTIVE

The Portfolio's objective is capital gain.

PRINCIPAL INVESTMENT STRATEGIES

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

The Portfolio invests at least 80% of its net assets, exclusive of government
securities, short-term notes, and cash and cash equivalents, in securities of
companies operating in the communications, information and related industries.
The Portfolio generally invests at least 65% of its total assets in securities
of companies engaged in these industries. The Portfolio may invest in companies
of any size.

The Portfolio may invest in securities of large companies that now are well
established in the world communications and information market and can be
expected to grow with the market. The Portfolio may also invest in
small-to-medium size companies that the investment manager believes provide
opportunities to benefit from the rapidly changing technologies and the
expansion of the communications, information and related industries.

The Portfolio uses a bottom-up stock selection approach. This means that the
investment manager uses extensive in-depth research into specific companies in
the communications, information and related industries to find those companies
that it believes offer the greatest prospects for future growth. In selecting
individual securities, the investment manager looks for companies that it
believes display or are expected to display:

     o    Robust growth prospects

     o    High profit margins or return on capital

     o    Attractive valuation relative to expected earnings or cash flow

     o    Quality management

     o    Unique competitive advantages

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

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


                                      P-1
<PAGE>


The Portfolio may purchase American Depositary Receipts (ADRs), which are
publicly traded instruments generally issued by domestic banks or trust
companies that represent a security of a foreign issuer. The Portfolio may
invest up to 15% of its net assets in illiquid securities (i.e., securities that
cannot be readily sold) and may invest up to 10% of its total assets directly in
foreign securities. The limit on foreign securities does not include ADRs, or
commercial paper and certificates of deposit issued by foreign banks. The
Portfolio may also purchase put options in an attempt to hedge against a decline
in the price of securities it holds. A put option gives the Portfolio the right
to sell an underlying security at a particular price during a fixed period.

The Portfolio may change its principal strategies, except for stated fundamental
policies, if the Fund's Board of Directors believes doing so is consistent with
the Portfolio's objective. The Portfolio's objective and any fundamental
policies may be changed only with shareholder approval. If a change of objective
or fundamental policies is proposed, Contract owners will be asked to give
voting instructions to the participating insurance companies. The Portfolio 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 Portfolio
from achieving its objective.


There is no guarantee that the Portfolio will achieve its objective.

PRINCIPAL RISKS

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

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


Stocks of companies in the technology sector, like those in which the Portfolio
may invest, have recently experienced a period of strong performance. However,
if investor sentiment changes, the value of technology stocks may decline. There
can be no assurances that the Portfolio will continue consistently to achieve,
by investing in initial public offerings or otherwise, substantially similar
performance that the Portfolio had previously experienced.


The Portfolio 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.

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

The Portfolio may actively and frequently trade stocks in its portfolio to carry
out its principal strategies. A high portfolio turnover rate increases
transaction costs which may increase the Portfolio's expenses.


Due to differences of tax treatment and other considerations, there is a
possibility that the interests of various Contract owners who own shares of the
Portfolio may conflict. The Board of Directors monitors events in order to
identify any disadvantages or material irreconcilable conflicts and to determine
what action, if any, should be taken in response.


An investment in the Portfolio 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 information below provides some indication of the risks of investing in the
Portfolio by showing how the performance of Class 1 shares of the Portfolio has
varied year to year, as well as how its performance compares to two widely-used
measures of performance. How the Portfolio has performed in the past, however,
is not necessarily an indication of how it will perform in the future.

Class 1 annual total returns presented in the bar chart and average annual total
returns presented in the table do not reflect the effect of any administration
fees or sales charges imposed by the Contracts on their owners. If these
expenses were included, the returns would be lower. Both the bar chart and table
assume that all dividends and capital gain distributions were reinvested.

Shareholder Information

PRICING OF FUND SHARES

When you buy or sell shares, you do so at the Portfolio's net asset value (NAV)
next calculated after your request is received by participating insurance
companies. If your purchase or sell request is received by participating
insurance companies by the close of regular trading on the New York Stock
Exchange (NYSE) (normally 4:00 p.m. Eastern time), it will be executed at the
Portfolio's NAV calculated as of the close of regular trading on the NYSE on
that day.

If your purchase or sell request is received by participating insurance
companies after the close of regular trading on the NYSE, your request will be
executed at the Portfolio's NAV calculated as of the close of regular trading on
the next NYSE trading day.

The NAV of the Portfolio is computed each day, Monday through Friday, on days
that the NYSE is open for trading. Securities owned by the Portfolio are valued
at current market prices. If reliable market prices are unavailable, securities
are valued in accordance with procedures approved by the Fund's Board of
Directors.


HOW TO PURCHASE AND SELL SHARES

The Portfolio is offering its shares only to Accounts of participating insurance
companies to fund benefits of the Contracts. The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.

An Account may sell all or any portion of the Portfolio shares that it holds at
any time at the next computed NAV per share, as described above. Portfolio
shares that are sold are entitled to any dividends that have been declared as
payable to record owners up to and including the day the sale is effected. There
is no charge. Payment of the sale price will normally be made within seven days
after receipt of such sale. In addition, the right to sell your shares may be
suspended and the date of payment of the sale price may be postponed for any
period during which the NYSE is closed (other than customary weekend and holiday
closings) or during which the Securities and Exchange Commission (SEC)
determines that trading thereon is restricted, or for any period during which an
emergency (as determined by the SEC) exists as a result of which the sale of
Portfolio shares is not reasonably practicable or as a result of which it is not
reasonably practicable for the Portfolio to fairly determine the value of its
net assets, or for such other periods as the SEC may by order permit for the
protection of shareholders.

Dividends and capital gain distributions from the Portfolio will be declared and
paid annually and will be reinvested in additional shares, at NAV, of the
Portfolio.


TAXES

Further information regarding the tax consequences of an investment in the
Portfolio is contained in the separate prospectuses and disclosure documents
issued by the participating insurance companies and accompanying this
Prospectus.

The Fund and the Portfolio

OVERVIEW OF THE FUND

Seligman Portfolios,  Inc. (the Fund) consists of 15 separate  portfolios.  This
Prospectus  contains  information about Seligman  Communications and Information
Portfolio (the Portfolio).



The Portfolio is offering its shares only to separate accounts (Accounts) of
participating insurance companies to fund benefits of variable annuity and
variable life insurance contracts (Contracts). The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.



The Portfolio offers two classes of shares: Class 1 shares and Class 2 shares.
This Prospectus offers only Class 2 shares and is for use with Accounts that
make Class 2 shares available to Contract owners.

INVESTMENT OBJECTIVE

The Portfolio's objective is capital gain.

PRINCIPAL INVESTMENT STRATEGIES

The Portfolio uses the following principal strategies to seek its objective: The
Portfolio invests at least 80% of its net assets, exclusive of government
securities, short-term notes, and cash and cash equivalents, in securities of
companies operating in the communications, information and related industries.
The Portfolio generally invests at least 65% of its total assets in securities
of companies engaged in these industries. The Portfolio may invest in companies
of any size.

The Portfolio may invest in securities of large companies that now are well
established in the world communications and information market and can be
expected to grow with the market. The Portfolio may also invest in
small-to-medium size companies that the investment manager believes provide
opportunities to benefit from the rapidly changing technologies and the
expansion of the communications, information and related industries.

The Portfolio uses a bottom-up stock selection approach. This means that the
investment manager uses extensive in-depth research into specific companies in
the communications, information and related industries to find those companies
that it believes offer the greatest prospects for future growth. In selecting
individual securities, the investment manager looks for companies that it
believes display or are expected to display:

     o    Robust growth prospects

     o    High profit margins or return on capital

     o    Attractive valuation relative to expected earnings or cash flow

     o    Quality management

     o    Unique competitive advantages

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

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


                                      P-1
<PAGE>


The Portfolio may purchase American Depositary Receipts (ADRs), which are
publicly traded instruments generally issued by domestic banks or trust
companies that represent a security of a foreign issuer. The Portfolio may
invest up to 15% of its net assets in illiquid securities (i.e., securities that
cannot be readily sold) and may invest up to 10% of its total assets directly in
foreign securities. The limit on foreign securities does not include ADRs, or
commercial paper and certificates of deposit issued by foreign banks. The
Portfolio may also purchase put options in an attempt to hedge against a decline
in the price of securities it holds. A put option gives the Portfolio the right
to sell an underlying security at a particular price during a fixed period.


The Portfolio may change its principal strategies, except for stated fundamental
policies, if the Fund's Board of Directors believes doing so is consistent with
the Portfolio's objective. The Portfolio's objective and any fundamental
policies may be changed only with shareholder approval. If a change of objective
or fundamental policies is proposed, Contract owners will be asked to give
voting instructions to the participating insurance companies.

The Portfolio 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 Portfolio from achieving its objective.


There is no guarantee that the Portfolio will achieve its objective.

PRINCIPAL RISKS

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

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


Stocks of companies in the technology sector, like those in which the Portfolio
may invest, have recently experienced a period of strong performance. However,
if investor sentiment changes, the value of technology stocks may decline. There
can be no assurances that the Portfolio will continue consistently to achieve,
by investing in initial public offerings or otherwise, substantially similar
performance that the Portfolio had previously experienced.


The Portfolio 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.

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

The Portfolio may actively and frequently trade stocks in its portfolio to carry
out its principal strategies. A high portfolio turnover rate increases
transaction costs which may increase the Portfolio's expenses.


Due to differences of tax treatment and other considerations, there is a
possibility that the interests of various Contract owners who own shares of the
Portfolio may conflict. The Board of Directors monitors events in order to
identify any disadvantages or material irreconcilable conflicts and to determine
what action, if any, should be taken in response.


An investment in the Portfolio 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

Class 2 shares are newly offered and have no performance history. The
information below provides some indication of the risks of investing in the
Portfolio by showing how the performance of Class 1 shares of the Portfolio has
varied year to year, as well as how its performance compares to two widely-used
measures of performance. How the Portfolio has performed in the past, however,
is not necessarily an indication of how it will perform in the future.

Total returns will vary between Class 1 shares and Class 2 shares due to
different expenses of the two Classes. Class 1 annual total returns presented in
the bar chart and average annual total returns presented in the table do not
reflect the effect of the shareholder servicing and distribution (12b-1) fees
associated with Class 2 shares or the effect of any administration fees or sales
charges imposed by the Contracts on their owners. If these expenses were
included, the returns would be lower. Both the bar chart and table assume that
all dividends and capital gain distributions were reinvested.

Shareholder Information

PRICING OF FUND SHARES

When you buy or sell shares, you do so at the Portfolio's net asset value (NAV)
next calculated after your request is received by participating insurance
companies. If your purchase or sell request is received by participating
insurance companies by the close of regular trading on the New York Stock
Exchange (NYSE) (normally 4:00 p.m. Eastern time), it will be executed at the
Portfolio's NAV calculated as of the close of regular trading on the NYSE on
that day.

If your purchase or sell request is received by participating insurance
companies after the close of regular trading on the NYSE, your request will be
executed at the Portfolio's NAV calculated as of the close of regular trading on
the next NYSE trading day.

The NAV of the Portfolio is computed each day, Monday through Friday, on days
that the NYSE is open for trading. Securities owned by the Portfolio are valued
at current market prices. If reliable market prices are unavailable, securities
are valued in accordance with procedures approved by the Fund's Board of
Directors.

HOW TO PURCHASE AND SELL SHARES

The Portfolio is offering its shares only to Accounts of participating insurance
companies to fund benefits of the Contracts. The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.

An Account may sell all or any portion of the Portfolio shares that it holds at
any time at the next computed NAV per share, as described above. Portfolio
shares that are sold are entitled to any dividends that have been declared as
payable to record owners up to and including the day the sale is effected. There
is no charge. Payment of the sale price will normally be made within seven days
after receipt of such sale. In addition, the right to sell your shares may be
suspended and the date of payment of the sale price may be postponed for any
period during which the NYSE is closed (other than customary weekend and holiday
closings) or during which the Securities and Exchange Commission (SEC)
determines that trading thereon is restricted, or for any period during which an
emergency (as determined by the SEC) exists as a result of which the sale of
Portfolio shares is not reasonably practicable or as a result of which it is not
reasonably practicable for the Portfolio to fairly determine the value of its
net assets, or for such other periods as the SEC may by order permit for the
protection of shareholders.

SHAREHOLDER SERVICING AND DISTRIBUTION ARRANGEMENTS

Under a Rule 12b-1 plan adopted by the Fund with respect to the Portfolio, Class
2 shares pay an annual shareholder servicing and distribution (12b-1) fee of up
to 0.25% of average net assets. The Portfolio pays this fee to Seligman
Advisors, Inc., the principal underwriter of the Portfolio's shares. Seligman
Advisors uses this fee to make payments to participating insurance companies or
their affiliates for services that the participating insurance companies provide
to Contract owners of Class 2 shares, and for distribution related expenses.
Because these 12b-1 fees are paid out of the Portfolio's assets on an ongoing
basis, over time they will increase the cost of a Contract owner's investment
and may cost you more than other types of sales charges.


                                       P-5
<PAGE>

DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS

Dividends and capital gain distributions from the Portfolio will be declared and
paid annually and will be reinvested in additional shares, at NAV, of the
Portfolio. Dividends on Class 2 shares generally will be lower than dividends on
Class 1 shares as a result of 12b-1 fees. Capital gain distributions will be
paid in the same amount for each Class.

TAXES

Further information regarding the tax consequences of an investment in the
Portfolio is contained in the separate prospectuses and disclosure documents
issued by the participating insurance companies and accompanying this
Prospectus.

Financial Highlights


The table below describes the Portfolio's performance for the past five years.
It is intended to help you understand the financial performance of the
Portfolio's Class 1 shares. Class 2 shares are a newly offered Class, effective
May 1, 2000, so financial highlights are not available. Certain information
reflects financial results for a single share of the Portfolio that was held
throughout the periods shown. "Total return" shows the rate that you would have
earned (or lost) on an investment in the Portfolio. Total returns do not reflect
the effect of the shareholder servicing and distribution (12b-1) fees associated
with Class 2 shares or any administration fees or sales charges imposed by the
Contracts on their owners. Ernst & Young llp, independent auditors, have audited
this information. Their report, along with the Portfolio's financial statements,
is included in the Fund's annual report, which is available upon request.

The Fund and the Portfolio

OVERVIEW OF THE FUND

Seligman Portfolios, Inc. (the Fund) consists of 15 separate portfolios. This
Prospectus contains information about Seligman Common Stock Portfolio (the
Portfolio).


The Portfolio is offering its shares only to separate accounts (Accounts) of
participating insurance companies to fund benefits of variable annuity and
variable life insurance contracts (Contracts). The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.


The Portfolio offers two classes of shares: Class 1 shares and Class 2 shares.
This Prospectus offers only Class 1 shares and is for use with Accounts that
make Class 1 shares available to Contract owners.

INVESTMENT OBJECTIVES

The Portfolio's objectives are to produce favorable, but not the highest,
current income and long-term growth of both income and capital value, without
exposing capital to undue risk.

PRINCIPAL INVESTMENT STRATEGIES

The Portfolio uses the following principal strategies to seek its objectives:

Generally, the Portfolio invests a majority of its assets in common stocks,
broadly diversified among a number of industries. The Portfolio usually invests
in the common stock of larger US companies; however, it may invest in companies
of any size. While common stocks have for many years been the predominant type
of security owned by the Portfolio, substantial portions of the Portfolio's
assets have been held, and may be held, in cash and fixed-income securities.

The Portfolio uses a bottom-up stock selection approach. This means the
investment manager concentrates on individual company fundamentals, rather than
on a particular industry. The Portfolio seeks to purchase strong, well-managed
companies that have the potential for solid earnings growth and dividend
increases.

The investment manager generally looks to identify companies that have
attractive dividend yields and that typically display relatively low valuations
based on one or more of the following measures: price-to-earnings, price-to-cash
flow, price-to-sales, and price-to-book value. The investment manager then uses
in-depth research into each company that meets its preliminary criteria to
identify those companies that it believes possess a catalyst for earnings
acceleration (i.e., a reason to expect a growth in earnings).

The Portfolio generally sells a stock if the investment manager believes one or
more of the following:

     o    The stock is over valued or fully valued

     o    Its dividend yield is not competitive compared to the yields offered
          by other securities in its industry

     o    Its earnings are disappointing or the catalyst for earnings
          acceleration no longer exists

     o    The company's underlying fundamentals have deteriorated

     o    There are more attractive investment opportunities

The Portfolio may purchase American Depositary Receipts (ADRs), which are
publicly traded instruments generally issued by domestic banks or trust
companies that represent a security of a foreign issuer. The Portfolio may
invest up to



                                      P-1
<PAGE>


15% of its net assets in illiquid securities (i.e., securities that
cannot be readily sold) and may invest up to 10% of its total assets directly in
foreign securities. The limit on foreign securities does not include ADRs, or
commercial paper and certificates of deposit issued by foreign banks. The
Portfolio generally does not invest a significant amount, if any, in illiquid or
foreign securities.

The Portfolio may change its principal strategies, except for stated fundamental
policies, if the Fund's Board of Directors believes doing so is consistent with
the Portfolio's objectives. The Portfolio's objectives and any fundamental
policies may be changed only with shareholder approval. If a change of objective
or fundamental policies is proposed, Contract owners will be asked to give
voting instructions to the participating insurance companies.

The Portfolio 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 Portfolio from achieving its objectives.

There is no guarantee that the Portfolio will achieve its objectives.


PRINCIPAL RISKS


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


The Portfolio may not invest more than 25% of its total assets in securities of
companies in any one industry. The Portfolio may, however, invest more heavily
in certain industries believed to offer good investment opportunities. If an
industry in which the Portfolio is invested falls out of favor, the Portfolio's
performance may be negatively affected.


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

Stocks of large US companies, like those in which the Portfolio generally
invests, have experienced an extended period of strong performance. However, if
investor sentiment changes, the value of large company stocks may decline. This
could have an adverse effect on the Portfolio's performance.

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


The Portfolio 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 Portfolio's expenses.


Due to differences of tax treatment and other considerations, there is a
possibility that the interests of various Contract owners who own shares of the
Portfolio may conflict. The Board of Directors monitors events in order to
identify any disadvantages or material irreconcilable conflicts and to determine
what action, if any, should be taken in response.


An investment in the Portfolio 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 information below provides some indication of the risks of investing in the
Portfolio by showing how the performance of Class 1 shares of the Portfolio has
varied year to year, as well as how its performance compares to two widely-used
measures of performance. How the Portfolio has performed in the past, however,
is not necessarily an indication of how it will perform in the future.

Class 1 annual total returns presented in the bar chart and average annual total
returns presented in the table do not reflect the effect of any administration
fees or sales charges imposed by the Contracts on their owners. If these
expenses were included, the returns would be lower. Both the bar chart and table
assume that all dividends and capital gain distributions were reinvested.

an unmanaged benchmark that assumes investment of dividends and excludes the

Shareholder Information

PRICING OF FUND SHARES

When you buy or sell shares, you do so at the Portfolio's net asset value (NAV)
next calculated after your request is received by participating insurance
companies. If your purchase or sell request is received by participating
insurance companies by the close of regular trading on the New York Stock
Exchange (NYSE) (normally 4:00 p.m. Eastern time), it will be executed at the
Portfolio's NAV calculated as of the close of regular trading on the NYSE on
that day.

If your purchase or sell request is received by participating insurance
companies after the close of regular trading on the NYSE, your request will be
executed at the Portfolio's NAV calculated as of the close of regular trading on
the next NYSE trading day.

The NAV of the Portfolio is computed each day, Monday through Friday, on days
that the NYSE is open for trading. Securities owned by the Portfolio are valued
at current market prices. If reliable market prices are unavailable, securities
are valued in accordance with procedures approved by the Fund's Board of
Directors.


HOW TO PURCHASE AND SELL SHARES

The Portfolio is offering its shares only to Accounts of participating insurance
companies to fund benefits of the Contracts. The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.

An Account may sell all or any portion of the Portfolio shares that it holds at
any time at the next computed NAV per share, as described above. Portfolio
shares that are sold are entitled to any dividends that have been declared as
payable to record owners up to and including the day the sale is effected. There
is no charge. Payment of the sale price will normally be made within seven days
after receipt of such sale. In addition, the right to sell your shares may be
suspended and the date of payment of the sale price may be postponed for any
period during which the NYSE is closed (other than customary weekend and holiday
closings) or during which the Securities and Exchange Commission (SEC)
determines that trading thereon is restricted, or for any period during which an
emergency (as determined by the SEC) exists as a result of which the sale of
Portfolio shares is not reasonably practicable or as a result of which it is not
reasonably practicable for the Portfolio to fairly determine the value of its
net assets, or for such other periods as the SEC may by order permit for the
protection of shareholders.

The table below describes the Portfolio's performance for the past five years.
It is intended to help you understand the financial performance of the
Portfolio's Class 1 shares. Certain information reflects financial results for a
single share of the Portfolio that was held throughout the periods shown. "Total
return" shows the rate that you would have earned (or lost) on an investment in
the Portfolio. Total returns do not reflect the effect of any administration
fees or sales charges imposed by the Contracts on their owners. Ernst & Young
LLP, independent auditors, have audited this information. Their report, along
with the Portfolio's financial statements, is included in the Fund's annual
report, which is available upon request.

The Fund and the Portfolio

OVERVIEW OF THE FUND

Seligman Portfolios, Inc. (the Fund) consists of 15 separate portfolios. This
Prospectus contains information about Seligman Common Stock Portfolio (the
Portfolio).


The Portfolio is offering its shares only to separate accounts (Accounts) of
participating insurance companies to fund benefits of variable annuity and
variable life insurance contracts (Contracts). The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.


The Portfolio offers two classes of shares: Class 1 shares and Class 2 shares.
This Prospectus offers only Class 2 shares and is for use with Accounts that
make Class 2 shares available to Contract owners.

INVESTMENT OBJECTIVES

The Portfolio's objectives are to produce favorable, but not the highest,
current income and long-term growth of both income and capital value, without
exposing capital to undue risk.

PRINCIPAL INVESTMENT STRATEGIES

The Portfolio uses the following principal strategies to seek its objectives:

Generally, the Portfolio invests a majority of its assets in common stocks,
broadly diversified among a number of industries. The Portfolio usually invests
in the common stock of larger US companies; however, it may invest in companies
of any size. While common stocks have for many years been the predominant type
of security owned by the Portfolio, substantial portions of the Portfolio's
assets have been held, and may be held, in cash and fixed-income securities.

The Portfolio uses a bottom-up stock selection approach. This means the
investment manager concentrates on individual company fundamentals, rather than
on a particular industry. The Portfolio seeks to purchase strong, well-managed
companies that have the potential for solid earnings growth and dividend
increases.

The investment manager generally looks to identify companies that have
attractive dividend yields and that typically display relatively low valuations
based on one or more of the following measures: price-to-earnings, price-to-cash
flow, price-to-sales, and price-to-book value. The investment manager then uses
in-depth research into each company that meets its preliminary criteria to
identify those companies that it believes possess a catalyst for earnings
acceleration (i.e., a reason to expect a growth in earnings).

The Portfolio generally sells a stock if the investment manager believes one or
more of the following:

     o    The stock is over valued or fully valued

     o    Its dividend yield is not competitive compared to the yields offered
          by other securities in its industry

     o    Its earnings are disappointing or the catalyst for earnings
          acceleration no longer exists

     o    The company's underlying fundamentals have deteriorated

     o    There are more attractive investment opportunities

The Portfolio may purchase American Depositary Receipts (ADRs), which are
publicly traded instruments generally issued by domestic banks or trust
companies that represent a security of a foreign issuer. The Portfolio may
invest up to


                                      P-1
<PAGE>


15% of its net assets in illiquid securities (i.e., securities that cannot be
readily sold) and may invest up to 10% of its total assets directly in foreign
securities. The limit on foreign securities does not include ADRs, or commercial
paper and certificates of deposit issued by foreign banks. The Portfolio
generally does not invest a significant amount, if any, in illiquid or foreign
securities.


The Portfolio may change its principal strategies, except for stated fundamental
policies, if the Fund's Board of Directors believes doing so is consistent with
the Portfolio's objectives. The Portfolio's objectives and any fundamental
policies may be changed only with shareholder approval. If a change of objective
or fundamental policies is proposed, Contract owners will be asked to give
voting instructions to the participating insurance companies.

The Portfolio 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 Portfolio from achieving its objectives.


There is no guarantee that the Portfolio will achieve its objectives.

PRINCIPAL RISKS


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


The Portfolio may not invest more than 25% of its total assets in securities of
companies in any one industry. The Portfolio may, however, invest more heavily
in certain industries believed to offer good investment opportunities. If an
industry in which the Portfolio is invested falls out of favor, the Portfolio's
performance may be negatively affected.

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


Stocks of large US companies, like those in which the Portfolio generally
invests, have experienced an extended period of strong performance. However, if
investor sentiment changes, the value of large company stocks may decline. This
could have an adverse effect on the Portfolio's performance.


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

The Portfolio 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 Portfolio's expenses.


Due to differences of tax treatment and other considerations, there is a
possibility that the interests of various Contract owners who own shares of the
Portfolio may conflict. The Board of Directors monitors events in order to
identify any disadvantages or material irreconcilable conflicts and to determine
what action, if any, should be taken in response.


An investment in the Portfolio 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

Class 2 shares are newly offered and have no performance history. The
information below provides some indication of the risks of investing in the
Portfolio by showing how the performance of Class 1 shares of the Portfolio has
varied year to year, as well as how its performance compares to two widely-used
measures of performance. How the Portfolio has performed in the past, however,
is not necessarily an indication of how it will perform in the future.


Total returns will vary between Class 1 shares and Class 2 shares due to
different expenses of the two Classes. Class 1 annual total returns presented in
the bar chart and average annual total returns presented in the table do not
reflect the effect of the shareholder servicing and distribution (12b-1) fees
associated with Class 2 shares or the effect of any administration fees or sales
charges imposed by the Contracts on their owners. If these expenses were
included, the returns would be lower. Both the bar chart and table assume that
all dividends and capital gain distributions were reinvested.

Shareholder Information

PRICING OF FUND SHARES

When you buy or sell shares, you do so at the Portfolio's net asset value (NAV)
next calculated after your request is received by participating insurance
companies. If your purchase or sell request is received by participating
insurance companies by the close of regular trading on the New York Stock
Exchange (NYSE) (normally 4:00 p.m. Eastern time), it will be executed at the
Portfolio's NAV calculated as of the close of regular trading on the NYSE on
that day.

If your purchase or sell request is received by participating insurance
companies after the close of regular trading on the NYSE, your request will be
executed at the Portfolio's NAV calculated as of the close of regular trading on
the next NYSE trading day.

The NAV of the Portfolio is computed each day, Monday through Friday, on days
that the NYSE is open for trading. Securities owned by the Portfolio are valued
at current market prices. If reliable market prices are unavailable, securities
are valued in accordance with procedures approved by the Fund's Board of
Directors.

HOW TO PURCHASE AND SELL SHARES

The Portfolio is offering its shares only to Accounts of participating insurance
companies to fund benefits of the Contracts. The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.

An Account may sell all or any portion of the Portfolio shares that it holds at
any time at the next computed NAV per share, as described above. Portfolio
shares that are sold are entitled to any dividends that have been declared as
payable to record owners up to and including the day the sale is effected. There
is no charge. Payment of the sale price will normally be made within seven days
after receipt of such sale. In addition, the right to sell your shares may be
suspended and the date of payment of the sale price may be postponed for any
period during which the NYSE is closed (other than customary weekend and holiday
closings) or during which the Securities and Exchange Commission (SEC)
determines that trading thereon is restricted, or for any period during which an
emergency (as determined by the SEC) exists as a result of which the sale of
Portfolio shares is not reasonably practicable or as a result of which it is not
reasonably practicable for the Portfolio to fairly determine the value of its
net assets, or for such other periods as the SEC may by order permit for the
protection of shareholders.


SHAREHOLDER SERVICING AND DISTRIBUTION ARRANGEMENTS

Under a Rule 12b-1 plan adopted by the Fund with respect to the Portfolio, Class
2 shares pay an annual shareholder servicing and distribution (12b-1) fee of up
to 0.25% of average net assets. The Portfolio pays this fee to Seligman
Advisors, Inc., the principal underwriter of the Portfolio's shares. Seligman
Advisors uses this fee to make payments to participating insurance companies or
their affiliates for services that the participating insurance companies provide
to Contract owners of Class 2 shares, and for distribution related expenses.
Because these 12b-1 fees are paid out of the Portfolio's assets on an ongoing
basis, over time they will increase the cost of a Contract owner's investment
and may cost you more than other types of sales charges.



                                      P-5
<PAGE>


DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS

Dividends and capital gain distributions from the Portfolio will be declared and
paid annually and will be reinvested in additional shares, at NAV, of the
Portfolio. Dividends on Class 2 shares generally will be lower than the
dividends on Class 1 shares as a result of 12b-1 fees. Capital gain
distributions will be paid in the same amount for each Class.

TAXES

Further information regarding the tax consequences of an investment in the
Portfolio is contained in the separate prospectuses and disclosure documents
issued by the participating insurance companies and accompanying this
Prospectus.

Financial Highlights


The table below describes the Portfolio's performance for the past five years.
It is intended to help you understand the financial performance of the
Portfolio's Class 1 shares. Class 2 shares are a newly offered Class, effective
May 1, 2000, so financial highlights are not available. Certain information
reflects financial results for a single share of the Portfolio that was held
throughout the periods shown. "Total return" shows the rate that you would have
earned (or lost) on an investment in the Portfolio. Total returns do not reflect
the effect of the shareholder servicing and distribution (12b-1) fees associated
with Class 2 shares or any administration fees or sales charges imposed by the
Contracts on their owners. Ernst & Young LLP, independent auditors, have audited
this information. Their report, along with the Portfolio's financial statements,
is included in the Fund's annual report, which is available upon request.

The Fund and the Portfolio

OVERVIEW OF THE FUND

Seligman Portfolios, Inc. (the Fund) consists of 15 separate portfolios. This
Prospectus contains information about Seligman Frontier Portfolio (the
Portfolio).


The Portfolio is offering its shares only to separate accounts (Accounts) of
participating insurance companies to fund benefits of variable annuity and
variable life insurance contracts (Contracts). The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.


The Portfolio offers two classes of shares: Class 1 shares and Class 2 shares.
This Prospectus offers only Class 1 shares and is for use with Accounts that
make Class 1 shares available to Contract owners.

INVESTMENT OBJECTIVE

The Portfolio's objective is growth of capital. Income may be considered but is
incidental to the Portfolio's investment objective.

PRINCIPAL INVESTMENT STRATEGIES

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

The Portfolio generally invests at least 65% of its total assets in the common
stock of small US companies. Companies are selected for their growth prospects.
The Portfolio uses a bottom-up stock selection approach. This means that the
investment manager concentrates on individual company fundamentals, rather than
on a particular market sector. The Portfolio maintains a disciplined investment
process that focuses on downside risks as well as upside potential. In selecting
investments, the investment manager looks to identify companies that typically
display one or more of the following:

     o    Positive operating cash flows

     o    Management ownership

     o    A unique competitive advantage

     o    Historically high returns on capital

- ------------------------------
Small Companies:

Companies with market
capitalizations, at the time
of purchase by the Portfolio,
of $1.25 billion or less.
- ------------------------------

The Portfolio generally sells a stock if its target price is reached, its
earnings are disappointing, its revenue growth slows, or its underlying
fundamentals deteriorate.

Although the Portfolio generally concentrates its investments in common stocks,
it may invest up to 35% of its assets in preferred stocks, securities
convertible into common stocks, and stock purchase warrants if the investment
manager believes they offer capital growth opportunities. The Portfolio may also
invest in American Depositary Receipts (ADRs), which are publicly-traded
instruments generally issued by domestic banks or trust companies that represent
a security of a foreign issuer. ADRs are quoted and settled in US dollars. The
Portfolio uses the same criteria in evaluating these securities as it does for
common stocks.

The Portfolio may invest up to 15% of its net assets in illiquid securities
(i.e., securities that cannot be readily sold), and may invest up to 10% of its
total assets directly in foreign securities. The limit on foreign securities
does not include ADRs, or commercial paper and certificates of deposit issued by
foreign banks. The Portfolio may also purchase put


                                      P-1
<PAGE>

options in an attempt to hedge against a decline in the price of securities it
holds in its portfolio and may lend portfolio securities. A put option gives the
Portfolio the right to sell an underlying security at a particular price during
a fixed period. The Portfolio generally does not invest a significant amount of
its assets, if any, in illiquid securities, foreign securities, or put options.


The Portfolio may change its principal strategies, except for stated fundamental
policies, if the Fund's Board of Directors believes doing so is consistent with
the Portfolio's objective. The Portfolio's objective and any fundamental
policies may be changed only with shareholder approval. If a change of objective
or fundamental policies is proposed, Contract owners will be asked to give
voting instructions to the participating insurance companies.

The Portfolio 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 Portfolio from achieving its objective.


The Fund's Board of Directors may change the definition of "small companies" if
it concludes that such a change is appropriate.

There is no guarantee that the Portfolio will achieve its objective.

PRINCIPAL RISKS

Stock prices fluctuate. Therefore, as with any portfolio that invests in stocks,
the Portfolio's net asset value will fluctuate, especially in the short term.
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.


Small company stocks, as a whole, may experience larger price fluctuations than
large-company stocks or other types of investments. Small companies tend to have
shorter operating histories, and may have less experienced management. During
periods of investor uncertainty, investor sentiment may favor large, well-known
companies over small, lesser-known companies.


The Portfolio may not invest more than 25% of its total assets in securities of
companies in any one industry. The Portfolio may, however, invest more heavily
in certain industries that the investment manager believes offer good investment
opportunities. If an industry in which the Portfolio is invested falls out of
favor, the Portfolio's performance may be negatively affected.

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

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

The Portfolio 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 Portfolio's expenses.


Due to differences of tax treatment and other considerations, there is a
possibility that the interests of various Contract owners who own shares of the
Portfolio may conflict. The Board of Directors monitors events in order to
identify any disadvantages or material irreconcilable conflicts and to determine
what action, if any, should be taken in response.

An investment in the Portfolio 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 information below provides some indication of the risks of investing in the
Portfolio by showing how the performance of Class 1 shares of the Portfolio has
varied year to year, as well as how its performance compares to three
widely-used measures of performance. How the Portfolio has performed in the
past, however, is not necessarily an indication of how it will perform in the
future.

Class 1 annual total returns presented in the bar chart and average annual total
returns presented in the table do not reflect the effect of any administration
fees or sales charges imposed by the Contracts on their owners. If these
expenses were included, the returns would be lower. Both the bar chart and table
assume that all dividends and capital gain distributions were reinvested.

Shareholder Information

PRICING OF FUND SHARES

When you buy or sell shares, you do so at the Portfolio's net asset value (NAV)
next calculated after your request is received by participating insurance
companies. If your purchase or sell request is received by participating
insurance companies by the close of regular trading on the New York Stock
Exchange (NYSE) (normally 4:00 p.m. Eastern time), it will be executed at the
Portfolio's NAV calculated as of the close of regular trading on the NYSE on
that day.

If your purchase or sell request is received by participating insurance
companies after the close of regular trading on the NYSE, your request will be
executed at the Portfolio's NAV calculated as of the close of regular trading on
the next NYSE trading day.

The NAV of the Portfolio is computed each day, Monday through Friday, on days
that the NYSE is open for trading. Securities owned by the Portfolio are valued
at current market prices. If reliable market prices are unavailable, securities
are valued in accordance with procedures approved by the Fund's Board of
Directors.


HOW TO PURCHASE AND SELL SHARES

The Portfolio is offering its shares only to Accounts of participating insurance
companies to fund benefits of the Contracts. The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.

An Account may sell all or any portion of the Portfolio shares that it holds at
any time at the next computed NAV per share, as described above. Portfolio
shares that are sold are entitled to any dividends that have been declared as
payable to record owners up to and including the day the sale is effected. There
is no charge. Payment of the sale price will normally be made within seven days
after receipt of such sale. In addition, the right to sell your shares may be
suspended and the date of payment of the sale price may be postponed for any
period during which the NYSE is closed (other than customary weekend and holiday
closings) or during which the Securities and Exchange Commission (SEC)
determines that trading thereon is restricted, or for any period during which an
emergency (as determined by the SEC) exists as a result of which the sale of
Portfolio shares is not reasonably practicable or as a result of which it is not
reasonably practicable for the Portfolio to fairly determine the value of its
net assets, or for such other periods as the SEC may by order permit for the
protection of shareholders.

DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS

Portfolio is contained in the separate prospectuses and disclosure documents
issued by the participating insurance companies and accompanying this

Financial Highlights

The table below describes the Portfolio's performance for the past five years.

The Fund and the Portfolio

OVERVIEW OF THE FUND

Seligman Portfolios, Inc. consists of 15 separate portfolios. This Prospectus
contains information about Seligman Frontier Portfolio (the Portfolio).


The Portfolio is offering its shares only to separate accounts (Accounts) of
participating insurance companies to fund benefits of variable annuity and
variable life insurance contracts (Contracts). The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.


The Portfolio offers two classes of shares: Class 1 shares and Class 2 shares.
This Prospectus offers only Class 2 shares and is for use with Accounts that
make Class 2 shares available to Contract owners.

INVESTMENT OBJECTIVE

The Portfolio's objective is growth of capital. Income may be considered but is
incidental to the Portfolio's investment objective.

PRINCIPAL INVESTMENT STRATEGIES

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

The Portfolio generally invests at least 65% of its total assets in the common
stock of small US companies. Companies are selected for their growth prospects.
The Portfolio uses a bottom-up stock selection approach. This means that the
investment manager concentrates on individual company fundamentals, rather than
on a particular market sector. The Portfolio maintains a disciplined investment
process that focuses on downside risks as well as upside potential. In selecting
investments, the investment manager looks to identify companies that typically
display one or more of the following:

o    Positive operating cash flows

o    Management ownership

o    A unique competitive advantage

o    Historically high returns on capital

- -----------------------------------------
Small Companies:

Companies with market capitalizations,
at the time of purchase by the Portfolio,
of $1.25 billion or less.
- -----------------------------------------

The Portfolio generally sells a stock if its target price is reached, its
earnings are disappointing, its revenue growth slows, or its underlying
fundamentals deteriorate.

Although the Portfolio generally concentrates its investments in common stocks,
it may invest up to 35% of its assets in preferred stocks, securities
convertible into common stocks, and stock purchase warrants if the investment
manager believes they offer capital growth opportunities. The Portfolio may also
invest in American Depositary Receipts (ADRs), which are publicly-traded
instruments generally issued by domestic banks or trust companies that represent
a security of a foreign issuer. ADRs are quoted and settled in USdollars. The
Portfolio uses the same criteria in evaluating these securities as it does for
common stocks.

The Portfolio may invest up to 15% of its net assets in illiquid securities
(i.e., securities that cannot be readily sold), and may invest up to 10% of its
total assets directly in foreign securities. The limit on foreign securities
does not include ADRs, or commercial paper and certificates of deposit issued by
foreign banks. The Portfolio may also purchase put


                                      P-1
<PAGE>

options in an attempt to hedge against a decline in the price of securities it
holds in its portfolio and may lend portfolio securities. A put option gives the
Portfolio the right to sell an underlying security at a particular price during
a fixed period. The Portfolio generally does not invest a significant amount of
its assets, if any, in illiquid securities, foreign securities, or put options.


The Portfolio may change its principal strategies, except for stated fundamental
policies, if the Fund's Board of Directors believes doing so is consistent with
the Portfolio's objective. The Portfolio's objective and any fundamental
policies may be changed only with shareholder approval. If a change of objective
or fundamental policies is proposed, Contract owners will be asked to give
voting instructions to the participating insurance companies.



The Portfolio 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 Portfolio from achieving its objective.


The Fund's Board of Directors may change the definition of "small companies" if
it concludes that such a change is appropriate.

There is no guarantee that the Portfolio will achieve its objective.

PRINCIPAL RISKS

Stock prices fluctuate. Therefore, as with any portfolio that invests in stocks,
the Portfolio's net asset value will fluctuate, especially in the short term.
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.


Small company stocks, as a whole, may experience larger price fluctuations than
large-company stocks or other types of investments. Small companies tend to have
shorter operating histories, and may have less experienced management. During
periods of investor uncertainty, investor sentiment may favor large, well-known
companies over smaller, lesser-known companies.


The Portfolio may not invest more than 25% of its total assets in securities of
companies in any one industry. The Portfolio may, however, invest more heavily
in certain industries that the investment manager believes offer good investment
opportunities. If an industry in which the Portfolio is invested falls out of
favor, the Portfolio's performance may be negatively affected.

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

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

The Portfolio 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 Portfolio's expenses.


Due to differences of tax treatment and other considerations, there is a
possibility that the interests of various Contract owners who own shares of the
Portfolio may conflict. The Board of Directors monitors events in order to
identify any disadvantages or material irreconcilable conflicts and to determine
what action, if any, should be taken in response.


An investment in the Portfolio 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

Class 2 shares are newly offered and have no performance history. The
information below provides some indication of the risks of investing in the
Portfolio by showing how the performance of Class 1 shares of the Portfolio has
varied year to year, as well as how its performance compares to three
widely-used measures of performance. How the Portfolio has performed in the
past, however, is not necessarily an indication of how it will perform in the
future.


Total returns will vary between Class 1 shares and Class 2 shares due to
different expenses of the two Classes. Class 1 annual total returns presented in
the bar chart and average annual total returns presented in the table do not
reflect the effect of the shareholder servicing and distribution (12b-1) fees
associated with Class 2 shares or the effect of any administration fees or sales
charges imposed by the Contracts on their owners. If these expenses were
included, the returns would be lower. Both the bar chart and table assume that
all dividends and capital gain distributions were reinvested.

Shareholder Information

PRICING OF FUND SHARES

When you buy or sell shares, you do so at the Portfolio's net asset value (NAV)
next calculated after your request is received by participating insurance
companies. If your purchase or sell request is received by participating
insurance companies by the close of regular trading on the New York Stock
Exchange (NYSE) (normally 4:00 p.m. Eastern time), it will be executed at the
Portfolio's NAV calculated as of the close of regular trading on the NYSE on
that day.

If your purchase or sell request is received by participating insurance
companies after the close of regular trading on the NYSE, your request will be
executed at the Portfolio's NAV calculated as of the close of regular trading on
the next NYSE trading day.

The NAV of the Portfolio is computed each day, Monday through Friday, on days
that the NYSE is open for trading. Securities owned by the Portfolio are valued
at current market prices. If reliable market prices are unavailable, securities
are valued in accordance with procedures approved by the Fund's Board of
Directors.

HOW TO PURCHASE AND SELL SHARES

The Portfolio is offering its shares only to Accounts of participating insurance
companies to fund benefits of the Contracts. The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.

An Account may sell all or any portion of the Portfolio shares that it holds at
any time at the next computed NAV per share, as described above. Portfolio
shares that are sold are entitled to any dividends that have been declared as
payable to record owners up to and including the day the sale is effected. There
is no charge. Payment of the sale price will normally be made within seven days
after receipt of such sale. In addition, the right to sell your shares may be
suspended and the date of payment of the sale price may be postponed for any
period during which the NYSE is closed (other than customary weekend and holiday
closings) or during which the Securities and Exchange Commission (SEC)
determines that trading thereon is restricted, or for any period during which an
emergency (as determined by the SEC) exists as a result of which the sale of
Portfolio shares is not reasonably practicable or as a result of which it is not
reasonably practicable for the Portfolio to fairly determine the value of its
net assets, or for such other periods as the SEC may by order permit for the
protection of shareholders.


SHAREHOLDER SERVICING AND DISTRIBUTION ARRANGEMENTS

Under a Rule 12b-1 plan adopted by the Fund with respect to the Portfolio, Class
2 shares pay an annual shareholder servicing and distribution (12b-1) fee of up
to 0.25% of average net assets. The Portfolio pays this fee to Seligman
Advisors, Inc., the principal underwriter of the Portfolio's shares. Seligman
Advisors uses this fee to make payments to participating insurance companies or
their affiliates for services that the participating insurance companies provide
to Contract owners of Class 2 shares, and for distribution related expenses.
Because these 12b-1 fees are paid out of the Portfolio's assets on an ongoing
basis, over time they will increase the cost of a Contract owner's investment
and may cost you more than other types of sales charges.



                                      P-5
<PAGE>


DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS

Dividends and capital gain distributions from the Portfolio will be declared and
paid annually and will be reinvested in additional shares, at NAV, of the
Portfolio. Dividends on Class 2 shares generally will be lower than the
dividends on Class 1 shares as a result of 12b-1 fees. Capital gain
distributions will be paid in the same amount for each Class.

TAXES

Further information regarding the tax consequences of an investment in the
Portfolio is contained in the separate prospectuses and disclosure documents
issued by the participating insurance companies and accompanying this
Prospectus.

Financial Highlights


The table below describes the Portfolio's performance for the past five years.
It is intended to help you understand the financial performance of the
Portfolio's Class 1 shares. Class 2 shares are a newly offered Class, effective
May 1, 2000, so financial highlights are not available. Certain information
reflects financial results for a single share of the Portfolio that was held
throughout the periods shown. "Total return" shows the rate that you would have
earned (or lost) on an investment in the Portfolio. Total returns do not reflect
the effect of the shareholder servicing and distribution (12b-1) fees associated
with Class 2 shares or any administration fees or sales charges imposed by the
Contracts on their owners. Ernst & Young LLP, independent auditors, have audited
this information. Their report, along with the Portfolio's financial statements,
is included in the Fund's annual report, which is available upon request.

The Fund and the Portfolio

OVERVIEW OF THE FUND

Seligman Portfolios, Inc. (the Fund) consists of 15 separate portfolios. This
Prospectus contains information about Seligman Global Growth Portfolio (the
Portfolio).


The Portfolio is offering its shares only to separate accounts (Accounts) of
participating insurance companies to fund benefits of variable annuity and
variable life insurance contracts (Contracts). The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.


The Portfolio offers two classes of shares: Class 1 shares and Class 2 shares.
This Prospectus offers only Class 1 shares and is for use with Accounts that
make Class 1 shares available to Contract owners.

INVESTMENT OBJECTIVE

The Portfolio's objective is long-term capital appreciation.

PRINCIPAL INVESTMENT STRATEGIES

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


The Portfolio 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 Portfolio may invest in companies of any size, domiciled in any
country. Typically, the Portfolio will invest in several countries in different
geographic regions.


The Portfolio uses an investment style that combines macro analysis of global
trends with in-depth research of individual companies. This means that the
investment manager analyzes the rapidly changing world to identify investment
themes that it believes will have the greatest impact on global markets, and
uses in-depth research to identify attractive companies around the world. The
Portfolio 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

     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 manager looks to identify
companies that it believes display one or more of the following:

     o    Attractive pricing relative to earnings forecasts or other valuation
          criteria (e.g., return on equity)

     o    Quality management and equity ownership by executives

     o    A unique competitive advantage (e.g., market share, proprietary
          products)

     o    Market liquidity

     o    Potential for improvement in overall operations

The Portfolio generally sells a stock if its target price is reached, its
earnings are disappointing, its revenue growth slows, or its underlying
fundamentals deteriorate. The Portfolio may also sell a stock if the investment
manager believes that a shifting in global trends may negatively affect a
company's outlook.


                                      P-1

<PAGE>


The Portfolio may invest in all types of securities, many of which will be
denominated in currencies other than the US dollar. Although the Portfolio
normally invests in equity securities, the Portfolio may invest up to 25% of its
assets in preferred stock and investment grade or comparable quality debt
securities. The Portfolio 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.

The Portfolio may invest up to 15% of its 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 Portfolio may also purchase put options in an
attempt to hedge against a decline in the price of securities it holds. A put
option gives the Portfolio the right to sell an underlying security at a
particular price during a fixed period.


The Portfolio may change its principal strategies, except for stated fundamental
policies, if the Fund's Board of Directors believes doing so is consistent with
the Portfolio's objective. The Portfolio's objective and any fundamental
policies may be changed only with shareholder approval. If a change of objective
or fundamental policies is proposed, contract owners will be asked to give
voting instructions to the participating insurance companies.

The Portolio 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 Portfolio from achieving its objective.


There is no guarantee that the Portfolio will achieve its objective.

PRINCIPAL RISKS

Stock prices fluctuate. Therefore, as with any portfolio that invests in stocks,
the Portfolio'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 currency fluctuations, foreign taxation, differences in
financial reporting practices, and changes in political conditions. There can be
no assurance that the Portfolio's foreign investments will present less risk
than a portfolio of solely US securities.

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


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


The Portfolio 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.

Options or illiquid securities in the Portfolio's investment portfolio involve
higher risk and may subject the Portfolio to higher price volatility.

The Portfolio 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 Portfolio's expenses.


Due to differences of tax treatment and other considerations, there is a
possibility that the interests of various Contract owners who own shares of the
Portfolio may conflict. The Board of Directors monitors events in order to
identify any disadvantages or material irreconcilable conflicts and to determine
what action, if any, should be taken in response.


An investment in the Portfolio 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 information below provides some indication of the risks of investing in the
Portfolio by showing how the performance of Class 1 shares of the Portfolio has
varied year to year, as well as how its performance compares to two widely-used
measures of performance. How the Portfolio has performed in the past, however,
is not necessarily an indication of how it will perform in the future.

Class 1 annual total returns presented in the bar chart and average annual total
returns presented in the table do not reflect the effect of any administration
fees or sales charges imposed by the Contracts on their owners. If these
expenses were included, the returns would be lower. Both the bar chart and table
assume that all dividends and capital gain distributions were reinvested.

Shareholder Information

PRICING OF FUND SHARES

When you buy or sell shares, you do so at the Portfolio's net asset value (NAV)
next calculated after your request is received by participating insurance
companies. If your purchase or sell request is received by participating
insurance companies by the close of regular trading on the New York Stock
Exchange (NYSE) (normally 4:00 p.m. Eastern time), it will be executed at the
Portfolio's NAV calculated as of the close of regular trading on the NYSE on
that day.

If your purchase or sell request is received by participating insurance
companies after the close of regular trading on the NYSE, your request will be
executed at the Portfolio's NAV calculated as of the close of regular trading on
the next NYSE trading day.

The NAV of the Portfolio is computed each day, Monday through Friday, on days
that the NYSE is open for trading. Securities owned by the Portfolio are valued
at current market prices. If reliable market prices are unavailable, securities
are valued in accordance with procedures approved by the Fund's Board of
Directors.


HOW TO PURCHASE AND SELL SHARES

The Portfolio is offering its shares only to Accounts of participating insurance
companies to fund benefits of the Contracts. The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.

An Account may sell all or any portion of the Portfolio shares that it holds at
any time at the next computed NAV per share, as described above. Portfolio
shares that are sold are entitled to any dividends that have been declared as
payable to record owners up to and including the day the sale is effected. There
is no charge. Payment of the sale price will normally be made within seven days
after receipt of such sale. In addition, the right to sell your shares may be
suspended and the date of payment of the sale price may be postponed for any
period during which the NYSE is closed (other than customary weekend and holiday
closings) or during which the Securities and Exchange Commission (SEC)
determines that trading thereon is restricted, or for any period during which an
emergency (as determined by the SEC) exists as a result of which the sale of
Portfolio shares is not reasonably practicable or as a result of which it is not
reasonably practicable for the Portfolio to fairly determine the value of its
net assets, or for such other periods as the SEC may by order permit for the
protection of shareholders.

Portfolio.


TAXES

Portfolio is contained in the separate prospectuses and disclosure documents
issued by the participating insurance companies and accompanying this

Financial Highlights

The Fund and the Portfolio

OVERVIEW OF THE FUND

Seligman Portfolios, Inc. (the Fund) consists of 15 separate portfolios. This
Prospectus contains information about Seligman Global Growth Portfolio (the
Portfolio).


The Portfolio is offering its shares only to separate accounts (Accounts) of
participating insurance companies to fund benefits of variable annuity and
variable life insurance contracts (Contracts). The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.


The Portfolio offers two classes of shares: Class 1 shares and Class 2 shares.
This Prospectus offers only Class 2 shares and is for use with Accounts that
make Class 2 shares available to Contract owners.

INVESTMENT OBJECTIVE

The Portfolio's objective is long-term capital appreciation.

PRINCIPAL INVESTMENT STRATEGIES

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


The Portfolio 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 Portfolio may invest in companies of any size, domiciled in any
country. Typically, the Portfolio will invest in several countries in different
geographic regions.


The Portfolio uses an investment style that combines macro analysis of global
trends with in-depth research of individual companies. This means that the
investment manager analyzes the rapidly changing world to identify investment
themes that it believes will have the greatest impact on global markets, and
uses in-depth research to identify attractive companies around the world. The
Portfolio 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

          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 manager looks to identify
companies that it believes display one or more of the following:

          o    Attractive pricing relative to earnings forecasts or other
               valuation criteria (e.g., return on equity)

          o    Quality management and equity ownership by executives

          o    A unique competitive advantage (e.g., market share, proprietary
               products)

          o    Market liquidity

          o    Potential for improvement in overall operations

The Portfolio generally sells a stock if its target price is reached, its
earnings are disappointing, its revenue growth slows, or its underlying
fundamentals deteriorate. The Portfolio may also sell a stock if the investment
manager believes that a shifting in global trends may negatively affect a
company's outlook.



                                      P-1
<PAGE>

The Portfolio may invest in all types of securities, many of which will be
denominated in currencies other than the US dollar. Although the Portfolio
normally invests in equity securities, the Portfolio may invest up to 25% of its
assets in preferred stock and investment grade or comparable quality debt
securities. The Portfolio 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.


The Portfolio may invest up to 15% of its 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 Portfolio may also purchase put options in an
attempt to hedge against a decline in the price of securities it holds. A put
option gives the Portfolio the right to sell an underlying security at a
particular price during a fixed period.

The Portfolio may change its principal strategies, except for stated fundamental
policies, if the Fund's Board of Directors believes doing so is consistent with
the Portfolio's objective. The Portfolio's objective and any fundamental
policies may be changed only with shareholder approval. If a change of objective
or fundamental policies is proposed, Contract owners will be asked to give
voting instructions to the participating insurance companies.

The Portfolio 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 Portfolio from achieving its objective.


There is no guarantee that the Portfolio will achieve its objective.

PRINCIPAL RISKS

Stock prices fluctuate. Therefore, as with any portfolio that invests in stocks,
the Portfolio'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 currency fluctuations, foreign taxation, differences in
financial reporting practices, and changes in political conditions. There can be
no assurance that the Portfolio's foreign investments will present less risk
than a portfolio of solely US securities.

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


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


The Portfolio 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.

Options or illiquid securities in the Portfolio's investment portfolio involve
higher risk and may subject the Portfolio to higher price volatility.


The Portfolio 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 Portfolio's expenses.

Due to differences of tax treatment and other considerations, there is a
possibility that the interests of various Contract owners who own shares of the
Portfolio may conflict. The Board of Directors monitors events in order to
identify any disadvantages or material irreconcilable conflicts and to determine
what action, if any, should be taken in response.


An investment in the Portfolio 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

Class 2 shares are newly offered and have no performance history. The
information below provides some indication of the risks of investing in the
Portfolio by showing how the performance of Class 1 shares of the Portfolio has
varied year to year, as well as how its performance compares to two widely-used
measures of performance. How the Portfolio has performed in the past, however,
is not necessarily an indication of how it will perform in the future.

Total returns will vary between Class 1 shares and Class 2 shares due to
different expenses of the two Classes. Class 1 annual total returns presented in
the bar chart and average annual total returns presented in the table do not
reflect the effect of the shareholder servicing and distribution (12b-1) fees
associated with Class 2 shares or the effect of any administration fees or sales
charges imposed by the Contracts on their owners. If these expenses were
included, the returns would be lower. Both the bar chart and table assume that
all dividends and capital gain distributions were reinvested.

Shareholder Information

PRICING OF FUND SHARES

When you buy or sell shares, you do so at the Portfolio's net asset value (NAV)
next calculated after your request is received by participating insurance
companies. If your purchase or sell request is received by participating
insurance companies by the close of regular trading on the New York Stock
Exchange (NYSE) (normally 4:00 p.m. Eastern time), it will be executed at the
Portfolio's NAV calculated as of the close of regular trading on the NYSE on
that day.

If your purchase or sell request is received by participating insurance
companies after the close of regular trading on the NYSE, your request will be
executed at the Portfolio's NAV calculated as of the close of regular trading on
the next NYSE trading day.

The NAV of the Portfolio is computed each day, Monday through Friday, on days
that the NYSE is open for trading. Securities owned by the Portfolio are valued
at current market prices. If reliable market prices are unavailable, securities
are valued in accordance with procedures approved by the Fund's Board of
Directors.

HOW TO PURCHASE AND SELL SHARES

The Portfolio is offering its shares only to Accounts of participating insurance
companies to fund benefits of the Contracts. The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.

An Account may sell all or any portion of the Portfolio shares that it holds at
any time at the next computed NAV per share, as described above. Portfolio
shares that are sold are entitled to any dividends that have been declared as
payable to record owners up to and including the day the sale is effected. There
is no charge. Payment of the sale price will normally be made within seven days
after receipt of such sale. In addition, the right to sell your shares may be
suspended and the date of payment of the sale price may be postponed for any
period during which the NYSE is closed (other than customary weekend and holiday
closings) or during which the Securities and Exchange Commission (SEC)
determines that trading thereon is restricted, or for any period during which an
emergency (as determined by the SEC) exists as a result of which the sale of
Portfolio shares is not reasonably practicable or as a result of which it is not
reasonably practicable for the Portfolio to fairly determine the value of its
net assets, or for such other periods as the SEC may by order permit for the
protection of shareholders.

SHAREHOLDER SERVICING AND DISTRIBUTION ARRANGEMENTS

Under a Rule 12b-1 plan adopted by the Fund with respect to the Portfolio, Class
2 shares pay an annual shareholder servicing and distribution (12b-1) fee of up
to 0.25% of average net assets. The Portfolio pays this fee to Seligman
Advisors, Inc., the principal underwriter of the Portfolio's shares. Seligman
Advisors uses this fee to make payments to participating insurance companies or
their affiliates for services that the participating insurance companies provide
to Contract owners of Class 2 shares, and for distribution related expenses.
Because these 12b-1 fees are paid out of the Portfolio's assets on an ongoing
basis, over time they will increase the cost of a Contract owner's investment
and may cost you more than other types of sales charges.


                                      P-5
<PAGE>

DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS

Dividends and capital gain distributions from the Portfolio will be declared and
paid annually and will be reinvested in additional shares, at NAV, of the
Portfolio. Dividends on Class 2 shares generally will be lower than the
dividends on Class 1 shares as a result of 12b-1 fees. Capital gain
distributions will be paid in the same amount for each Class.

TAXES

Further information regarding the tax consequences of an investment in the
Portfolio is contained in the separate prospectuses and disclosure documents
issued by the participating insurance companies and accompanying this
Prospectus.

Financial Highlights

The table below describes the Portfolio's performance for the period of the
Portfolio's operations. It is intended to help you understand the financial
performance of the Portfolio's Class 1 shares. Class 2 shares are a newly
offered Class, effective May 1, 2000, so financial highlights are not available.
Certain information reflects financial results for a single share of the
Portfolio that was held throughout the periods shown. "Total return" shows the
rate that you would have earned (or lost) on an investment in the Portfolio.
Total returns do not reflect the effect of the shareholder servicing and
distribution (12b-1) fees associated with Class 2 shares or any administration
fees or sales charges imposed by the Contracts on their owners. Ernst & Young
LLP, independent auditors, have audited this information. Their report, along
with the Portfolio's financial statements, is included in the Fund's annual
report, which is available upon request.

The Fund and the Portfolio

OVERVIEW OF THE FUND


Seligman Portfolios, Inc. (the Fund) consists of 15 separate portfolios. This
Prospectus contains information about Seligman Global Smaller Companies
Portfolio (the Portfolio).


The Portfolio is offering its shares only to separate accounts (Accounts) of
participating insurance companies to fund benefits of variable annuity and
variable life insurance contracts (Contracts). The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.


The Portfolio offers two classes of shares: Class 1 shares and Class 2 shares.
This Prospectus offers only Class 1 shares and is for use with Accounts that
make Class 1 shares available to Contract owners.

INVESTMENT OBJECTIVE

The Portfolio's objective is long-term capital appreciation.

PRINCIPAL INVESTMENT STRATEGIES

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

The Portfolio generally invests at least 65% of its assets in equity securities
of smaller US and non-US companies.

- ----------------------------------------
Smaller companies:

Companies with market capitalization, at
the time of purchase by the Portfolio,
equivalent to US $1 billion or less.
- ----------------------------------------

The Portfolio may invest in companies domiciled in any country, although it
typically invests in developed countries. The Portfolio will generally invest in
several countries in different geographic regions.

The Portfolio uses an investment style that combines macro analysis
with research into individual company attractiveness. This means that the
investment managers look to 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
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 to identify
companies that they believe display one or more of the following:

     o    Attractive pricing relative to earnings forecasts or other valuation
          criteria (e.g., return on equity)

     o    Quality management and equity ownership by executives

     o    A unique competitive advantage (e.g., market share, proprietary
          products)

     o    Market liquidity

     o    Potential for improvement in overall operations


                                      P-1

<PAGE>


The Portfolio generally sells a stock if its target price is reached, its
earnings are disappointing, its revenue growth slows, or its underlying
fundamentals deteriorate. The Portfolio anticipates that it will continue to
hold securities of companies that grow or expand so long as those investments
continue to offer prospects of long-term growth.


The Portfolio may invest in all types of securities, many of which will be
denominated in currencies other than the US dollar. Although the Portfolio
normally invests in equity securities, the Portfolio may invest up to 25% of its
assets in preferred stock and investment grade or comparable quality debt
securities. The Portfolio 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. Additionally, the
Portfolio may invest up to 35% of its assets in companies with market
capitalization of over $1 billion.


The Portfolio may invest up to 15% of its 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 Portfolio may also purchase put options in an
attempt to hedge against a decline in the price of securities it holds. A put
option gives the Portfolio the right to sell an underlying security at a
particular price during a fixed period.


The Portfolio may change its principal strategies, except for stated fundamental
policies, if the Fund's Board of Directors believes doing so is consistent with
the Portfolio's objective. The Portfolio's objective and any fundamental
policies may be changed only with shareholder approval. If a change of objective
or fundamental policies is proposed, Contract owners will be asked to give
voting instructions to the participating insurance companies.

The Portfolio 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 Portfolio from achieving its objective.


The Fund's Board of Directors may change the definition of "smaller companies"
if it concludes that such a change is appropriate.

There is no guarantee that the Portfolio will achieve its objective.

PRINCIPAL RISKS

Stock prices fluctuate. Therefore, as with any portfolio that invests in stocks,
the Portfolio'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 fluctuations, foreign
taxation, differences in financial reporting practices, and changes in political
conditions.


Small company stocks, as a whole, may experience larger price fluctuations than
large-company stocks or other types of investments. Small companies tend to have
shorter operating histories, and may have less experienced management. During
periods of investor uncertainty, investor sentiment may favor large, well-known
companies over small, lesser known companies.

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


Options or illiquid securities in the Portfolio's investment portfolio involve
higher risk and may subject the Portfolio to higher price volatility.

The Portfolio may actively and frequently trade stocks in its portfolio to carry
out its principal strategies. A high portfolio turnover rate increases
transaction costs which may increase the Portfolio's expenses.


Due to differences of tax treatment and other considerations, there is a
possibility that the interests of various Contract owners who own shares of the
Portfolio may conflict. The Board of Directors monitors events in order to
identify any disadvantages or material irreconcilable conflicts and to determine
what action, if any, should be taken in response.


An investment in the Portfolio 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 information below provides some indication of the risks of investing in the
Portfolio by showing how the performance of Class 1 shares of the Portfolio has
varied year to year, as well as how its performance compares to two widely-used
measures of performance. How the Portfolio has performed in the past, however,
is not necessarily an indication of how it will perform in the future.

Class 1 annual total returns presented in the bar chart and average annual total
returns presented in the table do not reflect the effect of any administration
fees or sales charges imposed by the Contracts on their owners. If these
expenses were included, the returns would be lower. Both the bar chart and table
assume that all dividends and capital gain distributions were reinvested.

Shareholder Information

PRICING OF FUND SHARES

When you buy or sell shares, you do so at the Portfolio's net asset value (NAV)
next calculated after your request is received by participating insurance
companies. If your purchase or sell request is received by participating
insurance companies by the close of regular trading on the New York Stock
Exchange (NYSE) (normally 4:00 p.m. Eastern time), it will be executed at the
Portfolio's NAV calculated as of the close of regular trading on the NYSE on
that day.

If your purchase or sell request is received by participating insurance
companies after the close of regular trading on the NYSE, your request will be
executed at the Portfolio's NAV calculated as of the close of regular trading on
the next NYSE trading day.

The NAV of the Portfolio is computed each day, Monday through Friday, on days
that the NYSE is open for trading. Securities owned by the Portfolio are valued
at current market prices. If reliable market prices are unavailable, securities
are valued in accordance with procedures approved by the Fund's Board of
Directors.

HOW TO PURCHASE AND SELL SHARES

The Portfolio is offering its shares only to Accounts of participating insurance
companies to fund benefits of the Contracts. The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.

An Account may sell all or any portion of the Portfolio shares that it holds at
any time at the next computed NAV per share, as described above. Portfolio
shares that are sold are entitled to any dividends that have been declared as
payable to record owners up to and including the day the sale is effected. There
is no charge. Payment of the sale price will normally be made within seven days
after receipt of such sale. In addition, the right to sell your shares may be
suspended and the date of payment of the sale price may be postponed for any
period during which the NYSE is closed (other than customary weekend and holiday
closings) or during which the Securities and Exchange Commission (SEC)
determines that trading thereon is restricted, or for any period during which an

Financial Highlights

The table below describes the Portfolio's performance for the past five years.
It is intended to help you understand the financial performance of the
Portfolio's Class 1 shares. Certain information reflects financial results for a
single share of the Portfolio that was held throughout the periods shown. "Total
return" shows the rate that you would have earned (or lost) on an investment in
the Portfolio. Total returns do not reflect the effect of any administration
fees or sales charges imposed by the Contracts on their owners. Ernst & Young
LLP, independent auditors, have audited this information. Their report, along
with the Portfolio's financial statements, is included in the Fund's annual
report, which is available upon request.

The Fund and the Portfolio

OVERVIEW OF THE FUND

Seligman Portfolios, Inc. (the Fund) consists of 15 separate portfolios. This
Prospectus contains information about Seligman Global Smaller Companies
Portfolio (the Portfolio).


The Portfolio is offering its shares only to separate accounts (Accounts) of
participating insurance companies to fund benefits of variable annuity and
variable life insurance contracts (Contracts). The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.


The Portfolio offers two classes of shares: Class 1 shares and Class 2 shares.
This Prospectus offers only Class 2 shares and is for use with Accounts that
make Class 2 shares available to Contract owners.

INVESTMENT OBJECTIVE

The Portfolio's objective is long-term capital appreciation.

PRINCIPAL INVESTMENT STRATEGIES

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

The Portfolio generally invests at least 65% of its assets in equity securities
of smaller US and non-US companies.

The Portfolio may invest in companies domiciled in any country, although it
typically invests in developed countries. The Portfolio will generally invest in
several countries in different geographic regions.

- ------------------------
Smaller companies:

Companies with market
capitalization, at the
time of purchase by the
Portfolio, equivalent to
US $1 billion or less.
- ------------------------

The Portfolio uses an investment style that combines macro analysis with
research into individual company attractiveness. This means that the investment
managers look to 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 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 to identify
companies that they believe display one or more of the following:

     o    Attractive pricing relative to earnings forecasts or other valuation
          criteria (e.g., return on equity)

     o    Quality management and equity ownership by executives

     o    A unique competitive advantage (e.g., market share, proprietary
          products)

     o    Market liquidity

     o    Potential for improvement in overall operations

The Portfolio generally sells a stock if its target price is reached, its
earnings are disappointing, its revenue growth slows, or its underlying
fundamentals deteriorate. The Portfolio anticipates that it will continue to
hold securities of companies that grow or expand so long as those investments
continue to offer prospects of long-term growth.


                                      P-1
<PAGE>



The Portfolio may invest in all types of securities, many of which will be
denominated in currencies other than the US dollar. Although the Portfolio
normally invests in equity securities, the Portfolio may invest up to 25% of its
assets in preferred stock and investment grade or comparable quality debt
securities. The Portfolio 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. Additionally, the
Portfolio may invest up to 35% of its assets in companies with market
capitalization of over $1 billion.


The Portfolio may invest up to 15% of its 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 Portfolio may also purchase put options in an
attempt to hedge against a decline in the price of securities it holds. A put
option gives the Portfolio the right to sell an underlying security at a
particular price during a fixed period.


The Portfolio may change its principal strategies, except for stated fundamental
policies, if the Fund's Board of Directors believes doing so is consistent with
the Portfolio's objective. The Portfolio's objective and any fundamental
policies may be changed only with shareholder approval. If a change of objective
or fundamental policies is proposed, Contract owners will be asked to give
voting instructions to the participating insurance companies.

The Portfolio 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 Portfolio from achieving its objective.


The Fund's Board of Directors may change the definition of "smaller companies"
if it concludes that such a change is appropriate.

There is no guarantee that the Portfolio will achieve its objective.

PRINCIPAL RISKS

Stock prices fluctuate. Therefore, as with any portfolio that invests in stocks,
the Portfolio'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 fluctuations, foreign
taxation, differences in financial reporting practices, and changes in political
conditions.


Small company stocks, as a whole, may experience larger price fluctuations than
large-company stocks or other types of investments. Small companies tend to have
shorter operating histories, and may have less experienced management. During
periods of investor uncertainty, investor sentiment may favor large, well-known
companies over small, lesser-known companies.


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

Options or illiquid securities in the Portfolio's investment portfolio involve
higher risk and may subject the Portfolio to higher price volatility.

The Portfolio may actively and frequently trade stocks in its portfolio to carry
out its principal strategies. A high portfolio turnover rate increases
transaction costs which may increase the Portfolio's expenses.


Due to differences of tax treatment and other considerations, there is a
possibility that the interests of various Contract owners who own shares of the
Portfolio may conflict. The Board of Directors monitors events in order to
identify any disadvantages or material irreconcilable conflicts and to determine
what action, if any, should be taken in response.


An investment in the Portfolio 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

Class 2 shares are newly offered and have no performance history. The
information below provides some indication of the risks of investing in the
Portfolio by showing how the performance of Class 1 shares of the Portfolio has
varied year to year, as well as how its performance compares to two widely-used
measures of performance. How the Portfolio has performed in the past, however,
is not necessarily an indication of how it will perform in the future.


Total returns will vary between Class 1 shares and Class 2 shares due to
different expenses of the two Classes. Class 1 annual total returns presented in
the bar chart and average annual total returns presented in the table do not
reflect the effect of the shareholder servicing and distribution (12b-1) fees
associated with Class 2 shares or the effect of any administration fees or sales
charges imposed by the Contracts on their owners. If these expenses were
included, the returns would be lower. Both the bar chart and table assume that
all dividends and capital gain distributions were reinvested.

Shareholder Information

PRICING OF FUND SHARES

When you buy or sell shares, you do so at the Portfolio's net asset value (NAV)
next calculated after your request is received by participating insurance
companies. If your purchase or sell request is received by participating
insurance companies by the close of regular trading on the New York Stock
Exchange (NYSE) (normally 4:00 p.m. Eastern time), it will be executed at the
Portfolio's NAV calculated as of the close of regular trading on the NYSE on
that day.

If your purchase or sell request is received by participating insurance
companies after the close of regular trading on the NYSE, your request will be
executed at the Portfolio's NAV calculated as of the close of regular trading on
the next NYSE trading day.

The NAV of the Portfolio is computed each day, Monday through Friday, on days
that the NYSE is open for trading. Securities owned by the Portfolio are valued
at current market prices. If reliable market prices are unavailable, securities
are valued in accordance with procedures approved by the Fund's Board of
Directors.

HOW TO PURCHASE AND SELL SHARES

The Portfolio is offering its shares only to Accounts of participating insurance
companies to fund benefits of the Contracts. The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.

An Account may sell all or any portion of the Portfolio shares that it holds at
any time at the next computed NAV per share, as described above. Portfolio
shares that are sold are entitled to any dividends that have been declared as
payable to record owners up to and including the day the sale is effected. There
is no charge. Payment of the sale price will normally be made within seven days
after receipt of such sale. In addition, the right to sell your shares may be
suspended and the date of payment of the sale price may be postponed for any
period during which the NYSE is closed (other than customary weekend and holiday
closings) or during which the Securities and Exchange Commission (SEC)
determines that trading thereon is restricted, or for any period during which an
emergency (as determined by the SEC) exists as a result of which the sale of
Portfolio shares is not reasonably practicable or as a result of which it is not
reasonably practicable for the Portfolio to fairly determine the value of its
net assets, or for such other periods as the SEC may by order permit for the
protection of shareholders.


SHAREHOLDER SERVICING AND DISTRIBUTION ARRANGEMENTS

Under a Rule 12b-1 plan adopted by the Fund with respect to the Portfolio, Class
2 shares pay an annual shareholder servicing and distribution (12b-1) fee of up
to 0.25% of average net assets. The Portfolio pays this fee to Seligman
Advisors, Inc., the principal underwriter of the Portfolio's shares. Seligman
Advisors uses this fee to make payments to participating insurance companies or
their affiliates for services that the participating insurance companies provide
to Contract owners of Class 2 shares, and for distribution related expenses.
Because these 12b-1 fees are paid out of the Portfolio's assets on an ongoing
basis, over time they will increase the cost of a Contract owner's investment
and may cost you more than other types of sales charges.



                                      P-5
<PAGE>


DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS

Dividends and capital gain distributions from the Portfolio will be declared and
paid annually and will be reinvested in additional shares, at NAV, of the
Portfolio. Dividends on Class 2 shares generally will be lower than the
dividends on Class 1 shares as a result of 12b-1 fees. Capital gain
distributions will be paid in the same amount for each Class.

TAXES

Further information regarding the tax consequences of an investment in the
Portfolio is contained in the separate prospectuses and disclosure documents
issued by the participating insurance companies and accompanying this
Prospectus.

Financial Highlights


The table below describes the Portfolio's performance for the past five years.
It is intended to help you understand the financial performance of the
Portfolio's Class 1 shares. Class 2 shares are a newly offered Class, effective
May 1, 2000, so financial highlights are not available. Certain information
reflects financial results for a single share of the Portfolio that was held
throughout the periods shown. "Total return" shows the rate that you would have
earned (or lost) on an investment in the Portfolio. Total returns do not reflect
the effect of the shareholder servicing and distribution (12b-1) fees associated
with Class 2 shares or any administration fees or sales charges imposed by the
Contracts on their owners. Ernst & Young LLP, independent auditors, have audited
this information. Their report, along with the Portfolio's financial statements,
is included in the Fund's annual report, which is available upon request.

comprises information technology and
communications, as well as medical,
environmental and biotechnology.
- ------------------------------------

The Portfolio may invest in companies domiciled in any country. The Portfolio
generally invests in several countries in different geographic regions.

The Portfolio 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 Portfolio. 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 Portfolio may invest in these companies as well.

The investment manager seeks to identify those technology companies that it
believes have the greatest prospects for future growth, no matter what their
country of origin. The Portfolio combines in-depth research into individual
companies with macro analysis. The investment manager looks for 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 manager looks for companies it believes display one or more of
the following:

     o    Robust growth prospects

     o    High profit margins

     o    Attractive valuation 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 Portfolio generally sells a stock if its target price is reached, its
earnings are disappointing, its revenue growth slows, or its underlying
fundamentals deteriorate.

The Portfolio may invest in all types of securities, many of which will be
denominated in currencies other than the US dollar. Although the Portfolio
normally invests in equity securities, the Portfolio may invest up to 25% of its
assets in preferred stock and investment grade or comparable quality debt
securities. The Portfolio 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.


The Portfolio may invest up to 15% of its 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 Portfolio may also purchase put options in an
attempt to hedge against a decline in the price of securities it holds. A put
option gives the Portfolio the right to sell an underlying security at a
particular price during a fixed period.

The Portfolio may change its principal strategies, except for stated fundamental
policies, if the Fund's Board of Directors believes doing so is consistent with
the Portfolio's objective. The Portfolio's objective and any fundamental
policies may be changed only with shareholder approval. If a change of objective
or fundamental policies is proposed, Contract owners will be asked to give
voting instructions to the participating insurance companies.

The Portfolio 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 Portfolio from achieving its objective.


There is no guarantee that the Portfolio will achieve its objective.


PRINCIPAL RISKS

Stock prices fluctuate. Therefore, as with any portfolio that invests in stocks,
the Portfolio'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 fluctuations, foreign
taxation, differences in financial reporting practices, and changes in political
conditions.


Stocks of companies in the technology sector, like those in which the Portfolio
may invest, have recently experienced a period of strong performance. However,
if investor sentiment changes, the value of technology stocks may decline. There
can be no assurances that the Portfolio will continue consistently to achieve,
by investing in initial public offerings or otherwise, substantially similar
performance that the Portfolio had previously experienced.


The Portfolio may be susceptible to factors affecting technology and
technology-related industries and the Portfolio's net asset value may fluctuate
more than a portfolio that invests in a wider range of portfolio securities.
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 Portfolio 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 Portfolio's entire investment
portfolio. However, a decline in the value of one of the Portfolio's investments
may offset potential gains from other investments.

The Portfolio 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.

Options or illiquid securities in the Portfolio's investment portfolio involve
higher risk and may subject the Portfolio to higher price volatility.

The Portfolio 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 Portfolio's expenses.


Due to differences of tax treatment and other considerations, there is a
possibility that the interests of various Contract owners who own shares of the
Portfolio may conflict. The Board of Directors monitors events in order to
identify any disadvantages or material irreconcilable conflicts and to determine
what action, if any, should be taken in response.


An investment in the Portfolio 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 information below provides some indication of the risks of investing in the
Portfolio by showing how the performance of Class 1 shares of the Portfolio has
varied year to year, as well as how its performance compares to three
widely-used measures of performance. How the Portfolio has performed in the
past, however, is not necessarily an indication of how it will perform in the
future.

Class 1 annual total returns presented in the bar chart and average annual total
returns presented in the table do not reflect the effect of any administration
fees or sales charges imposed by the Contracts on their owners. If these
expenses were included, the returns would be lower. Both the bar chart and table
assume that all dividends and capital gain distributions were reinvested.

MANAGEMENT OF THE FUND

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

J. & W. Seligman & Co. Incorporated (Seligman), 100 Park Avenue, New York, New

Portfolio based on the assets under HIML's supervision. This fee did not affect
the fees paid by the Portfolio.

Shareholder Information

PRICING OF FUND SHARES

When you buy or sell shares, you do so at the Portfolio's net asset value (NAV)
next calculated after your request is received by participating insurance
companies. If your purchase or sell request is received by participating
insurance companies by the close of regular trading on the New York Stock
Exchange (NYSE) (normally 4:00 p.m. Eastern time), it will be executed at the
Portfolio's NAV calculated as of the close of regular trading on the NYSE on
that day.

If your purchase or sell request is received by participating insurance
companies after the close of regular trading on the NYSE, your request will be
executed at the Portfolio's NAV calculated as of the close of regular trading on
the next NYSE trading day.

The NAV of the Portfolio is computed each day, Monday through Friday, on days
that the NYSE is open for trading. Securities owned by the Portfolio are valued
at current market prices. If reliable market prices are unavailable, securities
are valued in accordance with procedures approved by the Fund's Board of
Directors.


HOW TO PURCHASE AND SELL SHARES

The Portfolio is offering its shares only to Accounts of participating insurance
companies to fund benefits of the Contracts. The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.

An Account may sell all or any portion of the Portfolio shares that it holds at
any time at the next computed NAV per share, as described above. Portfolio
shares that are sold are entitled to any dividends that have been declared as
payable to record owners up to and including the day the sale is effected. There
is no charge. Payment of the sale price will normally be made within seven days
after receipt of such sale. In addition, the right to sell your shares may be
suspended and the date of payment of the sale price may be postponed for any
period during which the NYSE is closed (other than customary weekend and holiday
closings) or during which the Securities and Exchange Commission (SEC)
determines that trading thereon is restricted, or for any period during which an
emergency (as determined by the SEC) exists as a result of which the sale of
Portfolio shares is not reasonably practicable or as a result of which it is not
reasonably practicable for the Portfolio to fairly determine the value of its
net assets, or for such other periods as the SEC may by order permit for the
protection of shareholders.

DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS

Dividends and capital gain distributions from the Portfolio will be declared and
paid annually and will be reinvested in additional shares, at NAV, of the
Portfolio.


TAXES

Further information regarding the tax consequences of an investment in the
Portfolio is contained in the separate prospectuses and disclosure documents
issued by the participating insurance companies and accompanying this
Prospectus.

Financial Highlights

The table below describes the Portfolio's performance for the period of the
Portfolio's operations. It is intended to help you understand the financial
performance of the Portfolio's Class 1 shares. Certain information reflects
financial results for a single share of the Portfolio that was held throughout
the periods shown. "Total return" shows the rate that you would have earned (or
lost) on an investment in the Portfolio. Total returns do not reflect the effect
of any administration fees or sales charges imposed by the Contracts on their
owners. Ernst & Young LLP, independent auditors, have audited this information.
Their report, along with the Portfolio's financial statements, is included in
the Fund's annual report, which is available upon request.

The Securities and Exchange Commission has neither approved nor disapproved this
Fund, and it has not determined the prospectus to be accurate or adequate. Any
representation to the contrary is a criminal offense.

An investment in this Fund or any other fund cannot provide a complete

The Fund and the Portfolio

OVERVIEW OF THE FUND

Seligman Portfolios, Inc. (the Fund) consists of 15 separate portfolios. This
Prospectus contains information about Seligman Global Technology Portfolio (the
Portfolio).


The Portfolio is offering its shares only to separate accounts (Accounts) of
participating insurance companies to fund benefits of variable annuity and
variable life insurance contracts (Contracts). The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.


The Portfolio offers two classes of shares: Class 1 shares and Class 2 shares.
This Prospectus offers only Class 2 shares and is for use with Accounts that
make Class 2 shares available to Contract owners.

INVESTMENT OBJECTIVE

The Portfolio's objective is long-term capital appreciation.

PRINCIPAL INVESTMENT STRATEGIES

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

The Portfolio 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:

The use of science to create new
products and services. The industry
comprises information technology and
communications, as well as medical,
environmental and biotechnology.

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

The Portfolio may invest in companies domiciled in any country. The Portfolio
generally invests in several countries in different geographic regions.

The Portfolio 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 Portfolio. 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 Portfolio may invest in these companies as well.

The investment manager seeks to identify those technology companies that it
believes have the greatest prospects for future growth, no matter what their
country of origin. The Portfolio combines in-depth research into individual
companies with macro analysis. The investment manager looks for 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 manager looks for companies it believes display one or more of
the following:

     o    Robust growth prospects

     o    High profit margins

     o    Attractive valuation 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 Portfolio generally sells a stock if its target price is reached, its
earnings are disappointing, its revenue growth slows, or its underlying
fundamentals deteriorate.


                                      P-1
<PAGE>

The Portfolio may invest in all types of securities, many of which will be
denominated in currencies other than the US dollar. Although the Portfolio
normally invests in equity securities, the Portfolio may invest up to 25% of its
assets in preferred stock and investment grade or comparable quality debt
securities. The Portfolio 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.

The Portfolio may invest up to 15% of its 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 Portfolio may also purchase put options in an
attempt to hedge against a decline in the price of securities it holds. A put
option gives the Portfolio the right to sell an underlying security at a
particular price during a fixed period.


The Portfolio may change its principal strategies, except for stated fundamental
policies, if the Fund's Board of Directors believes doing so is consistent with
the Portfolio's objective. The Portfolio's objective and any fundamental
policies may be changed only with shareholder approval. If a change of objective
or fundamental policies is proposed, Contract owners will be asked to give
voting instructions to the participating insurance companies.

The Portfolio 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 Portfolio from achieving its objective.


There is no guarantee that the Portfolio will achieve its objective.

PRINCIPAL RISKS

Stock prices fluctuate. Therefore, as with any portfolio that invests in stocks,
the Portfolio'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 fluctuations, foreign
taxation, differences in financial reporting practices, and changes in political
conditions.


Stocks of companies in the technology sector, like those in which the Portfolio
may invest, have recently experienced a period of strong performance. However,
if investor sentiment changes, the value of technology stocks may decline. There
can be no assurances that the Portfolio will continue consistently to achieve,
by investing in initial public offerings or otherwise, substantially similar
performance that the Portfolio had previously experienced.


The Portfolio may be susceptible to factors affecting technology and
technology-related industries and the Portfolio's net asset value may fluctuate
more than a portfolio that invests in a wider range of portfolio securities.
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 Portfolio 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 Portfolio's entire investment
portfolio. However, a decline in the value of one of the Portfolio's investments
may offset potential gains from other investments.

The Portfolio 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.

Options or illiquid securities in the Portfolio's investment portfolio involve
higher risk and may subject the Portfolio to higher price volatility.

The Portfolio 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 Portfolio's expenses.


Due to differences of tax treatment and other considerations, there is a
possibility that the interests of various Contract owners who own shares of the
Portfolio may conflict. The Board of Directors monitors events in order to
identify any disadvantages or material irreconcilable conflicts and to determine
what action, if any, should be taken in response.


An investment in the Portfolio 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

Class 2 shares are newly offered and have no performance history. The
information below provides some indication of the risks of investing in the
Portfolio by showing how the performance of Class 1 shares of the Portfolio has
varied year to year, as well as how its performance compares to three
widely-used measures of performance. How the Portfolio has performed in the
past, however, is not necessarily an indication of how it will perform in the
future.


Total returns will vary between Class 1 shares and Class 2 shares due to
different expenses of the two Classes. Class 1 annual total returns presented in
the bar chart and average annual total returns presented in the table do not
reflect the effect of the shareholder servicing and distribution (12b-1) fees
associated with Class 2 shares or the effect of any administration fees or sales
charges imposed by the Contracts on their owners. If these expenses were
included, the returns would be lower. Both the bar chart and table assume that
all dividends and capital gain distributions were reinvested.

Shareholder Information

PRICING OF FUND SHARES

When you buy or sell shares, you do so at the Portfolio's net asset value (NAV)
next calculated after your request is received by participating insurance
companies. If your purchase or sell request is received by participating
insurance companies by the close of regular trading on the New York Stock
Exchange (NYSE) (normally 4:00 p.m. Eastern time), it will be executed at the
Portfolio's NAV calculated as of the close of regular trading on the NYSE on
that day.

If your purchase or sell request is received by participating insurance
companies after the close of regular trading on the NYSE, your request will be
executed at the Portfolio's NAV calculated as of the close of regular trading on
the next NYSE trading day.

The NAV of the Portfolio is computed each day, Monday through Friday, on days
that the NYSE is open for trading. Securities owned by the Portfolio are valued
at current market prices. If reliable market prices are unavailable, securities
are valued in accordance with procedures approved by the Fund's Board of
Directors.

HOW TO PURCHASE AND SELL SHARES

The Portfolio is offering its shares only to Accounts of participating insurance
companies to fund benefits of the Contracts. The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.

An Account may sell all or any portion of the Portfolio shares that it holds at
any time at the next computed NAV per share, as described above. Portfolio
shares that are sold are entitled to any dividends that have been declared as
payable to record owners up to and including the day the sale is effected. There
is no charge. Payment of the sale price will normally be made within seven days
after receipt of such sale. In addition, the right to sell your shares may be
suspended and the date of payment of the sale price may be postponed for any
period during which the NYSE is closed (other than customary weekend and holiday
closings) or during which the Securities and Exchange Commission (SEC)
determines that trading thereon is restricted, or for any period during which an
emergency (as determined by the SEC) exists as a result of which the sale of
Portfolio shares is not reasonably practicable or as a result of which it is not
reasonably practicable for the Portfolio to fairly determine the value of its
net assets, or for such other periods as the SEC may by order permit for the
protection of shareholders.


SHAREHOLDER SERVICING AND DISTRIBUTION ARRANGEMENTS

Under a Rule 12b-1 plan adopted by the Fund with respect to the Portfolio, Class
2 shares pay an annual shareholder servicing and distribution (12b-1) fee of up
to 0.25% of average net assets. The Portfolio pays this fee to Seligman
Advisors, Inc., the principal underwriter of the Portfolio's shares. Seligman
Advisors uses this fee to make payments to participating insurance companies or
their affiliates for services that the participating insurance companies provide
to Contract owners of Class 2 shares, and for distribution related expenses.
Because these 12b-1 fees are paid out of the Portfolio's assets on an ongoing
basis, over time they will increase the cost of a Contract owner's investment
and may cost you more than other types of sales charges.



                                      P-5
<PAGE>


DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS

Dividends and capital gain distributions from the Portfolio will be declared and
paid annually and will be reinvested in additional shares, at NAV, of the
Portfolio. Dividends on Class 2 shares generally will be lower than the
dividends on Class 1 shares as a result of 12b-1 fees. Capital gain
distributions will be paid in the same amount for each Class.

TAXES

Further information regarding the tax consequences of an investment in the
Portfolio is contained in the separate prospectuses and disclosure documents
issued by the participating insurance companies and accompanying this
Prospectus.

Financial Highlights


The table below describes the Portfolio's performance for the period of the
Portfolio's operations. It is intended to help you understand the financial
performance of the Portfolio's Class 1 shares. Class 2 shares are a newly
offered Class, effective May 1, 2000, so financial highlights are not available.
Certain information reflects financial results for a single share of the
Portfolio that was held throughout the periods shown. "Total return" shows the
rate that you would have earned (or lost) on an investment in the Portfolio.
Total returns do not reflect the effect of the shareholder servicing and
distribution (12b-1) fees associated with Class 2 shares or any administration
fees or sales charges imposed by the Contracts on their owners. Ernst & Young
LLP, independent auditors, have audited this information. Their report, along
with the Portfolio's financial statements, is included in the Fund's annual
report, which is available upon request.

The Fund and the Portfolio

OVERVIEW OF THE FUND

Seligman Portfolios, Inc. (the Fund) consists of 15 separate portfolios. This
Prospectus contains information about Seligman International Growth Portfolio
(the Portfolio).


The Portfolio is offering its shares only to separate accounts (Accounts) of
participating insurance companies to fund benefits of variable annuity and
variable life insurance contracts (Contracts). The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.


The Portfolio offers two classes of shares: Class 1 shares and Class 2 shares.
This Prospectus offers only Class 1 shares and is for use with Accounts that
make Class 1 shares available to Contract owners.

INVESTMENT OBJECTIVE

The Portfolio's objective is long-term capital appreciation.

PRINCIPAL INVESTMENT STRATEGIES

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

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

While the Portfolio may invest in companies of any size, it generally invests in
medium to large-sized companies in the principal international markets. It may
also invest in companies with lower market capitalization or in smaller regional
or emerging markets.

The Portfolio uses a top-down investment style when choosing securities to
purchase. This means the investment manager concentrates first on regional and
country allocations, then on industry sectors, followed by fundamental analysis
of individual companies. The Portfolio'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 pricing relative to earnings forecasts or other valuation
          criteria (e.g., return on equity)

     o    Quality management and equity ownership by executives

     o    A unique competitive advantage (e.g., market share, proprietary
          products)

     o    Market liquidity

     o    Potential for improvement in overall operations


                                       P-1

<PAGE>


The Portfolio generally sells a stock if its target price is reached, its
earnings are disappointing, its revenue growth slows, or its underlying
fundamentals deteriorate. The Portfolio may also sell a stock if the investment
manager believes that negative country or regional factors may affect a
company's outlook.

The Portfolio 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. Although the Portfolio normally invests in equity securities, the
Portfolio may invest up to 25% of its assets in preferred stock and investment
grade or comparable quality debt securities. The Portfolio 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.

The Portfolio may invest up to 15% of its 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 Portfolio may also purchase put options in an
attempt to hedge against a decline in the price of securities it holds in its
portfolio. A put option gives the Portfolio the right to sell an underlying
security at a particular price during a fixed period.


The Portfolio may change its principal strategies, except for stated fundamental
policies, if the Fund's Board of Directors believes doing so is consistent with
the Portfolio's objective. The Portfolio's objective and any fundamental
policies may be changed only with shareholder approval. If a change of objective
or fundamental policies is proposed, Contract owners will be asked to give
voting instructions to the participating insurance companies.

The Portfolio 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 Portfolio from achieving its objective.


There is no guarantee that the Portfolio will achieve its objective.

PRINCIPAL RISKS

Stock prices fluctuate. Therefore, as with any portfolio that invests in stocks,
the Portfolio'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 fluctuations, foreign
taxation, differences in financial reporting practices, and changes in political
conditions. There can be no assurance that the Portfolio's foreign investments
will present less risk than a portfolio of solely US securities.

The Portfolio 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
Portfolio's entire investment portfolio. However, a decline in the value of the
Portfolio's investments in one country may offset potential gains from
investments in another country.

The Portfolio 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.


Options or illiquid securities in the Portfolio's investment portfolio involve
higher risk and may subject the Portfolio to higher price volatility.


The Portfolio 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 Portfolio's expenses.


Due to differences of tax treatment and other considerations, there is a
possibility that the interests of various Contract owners who own shares of the
Portfolio may conflict. The Board of Directors monitors events in order to
identify any disadvantages or material irreconcilable conflicts and to determine
what action, if any, should be taken in response.


An investment in the Portfolio 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 information below provides some indication of the risks of investing in the
Portfolio by showing how the performance of Class 1 shares of the Portfolio has
varied year to year, as well as how its performance compares to two widely-used
measures of performance. How the Portfolio has performed in the past, however,
is not necessarily an indication of how it will perform in the future.

Class 1 annual total returns presented in the bar chart and average annual total
returns presented in the table do not reflect the effect of any administration
fees or sales charges imposed by the Contracts on their owners. If these
expenses were included, the returns would be lower. Both the bar chart and table
assume that all dividends and capital gain distributions were reinvested.

MANAGEMENT OF THE FUND

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

J. & W. Seligman & Co. Incorporated (Seligman), 100 Park Avenue, New York, New
York 10017, is the manager of the Fund. Seligman provides investment management
services for the Portfolio, including making purchases and sales of securities
for the Portfolio, consistent with the Portfolio's investment objective and
strategies, and administers the Portfolio's business and other affairs.


Established in 1864, Seligman currently serves as manager to 20 US registered
investment companies, which offer more than 50 investment portfolios with
approximately $30 billion in assets as of March 31, 2000. Seligman also provides
investment management or advice to institutional or other accounts having an
aggregate value at March 31, 2000 of approximately $12 billion.

The Portfolio pays Seligman a management fee for its services, equal to a
percentage of the Portfolio's average daily net assets, as follows: 1.00% on
first $1 billion; .95% on next $1 billion; and .90% thereafter. For the year
ended December 31, 1999, the Portfolio paid Seligman a management fee equal to
an annual rate of 1.00% of its average daily net assets.

Prior to March 31, 2000, Henderson Investment Management Limited (HIML) served
as a subadviser to the Portfolio. HIML, established in 1984, is a wholly owned
subsidiary of Henderson plc, a United Kingdom corporation. For the year ended
December 31, 1999, Seligman paid HIML a fee for its services in respect of the
Portfolio based on the assets under HIML's supervision. This fee did not affect
the fees paid by the Portfolio.

Portfolio Management

The Portfolio is managed by Mr. Jack P. Chang, co-leader of Seligman's Global
Growth Team.

Mr. Chang joined Seligman on September 20, 1999 as a Managing Director. He is a

Prior thereto, he was a Portfolio Manager with Columbia Management Company from

Shareholder Information

PRICING OF FUND SHARES

When you buy or sell shares, you do so at the Portfolio's net asset value (NAV)
next calculated after your request is received by participating insurance
companies. If your purchase or sell request is received by participating
insurance companies by the close of regular trading on the New York Stock
Exchange (NYSE) (normally 4:00 p.m. Eastern time), it will be executed at the
Portfolio's NAV calculated as of the close of regular trading on the NYSE on
that day.

If your purchase or sell request is received by participating insurance
companies after the close of regular trading on the NYSE, your request will be
executed at the Portfolio's NAV calculated as of the close of regular trading on
the next NYSE trading day.

The NAV of the Portfolio is computed each day, Monday through Friday, on days
that the NYSE is open for trading. Securities owned by the Portfolio are valued
at current market prices. If reliable market prices are unavailable, securities
are valued in accordance with procedures approved by the Fund's Board of
Directors.

HOW TO PURCHASE AND SELL SHARES

The Portfolio is offering its shares only to Accounts of participating insurance
companies to fund benefits of the Contracts. The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.

An Account may sell all or any portion of the Portfolio shares that it holds at
any time at the next computed NAV per share, as described above. Portfolio
shares that are sold are entitled to any dividends that have been declared as
payable to record owners up to and including the day the sale is effected. There
is no charge. Payment of the sale price will normally be made within seven days
after receipt of such sale. In addition, the right to sell your shares may be
suspended and the date of payment of the sale price may be postponed for any
period during which the NYSE is closed (other than customary weekend and holiday
closings) or during which the Securities and Exchange Commission (SEC)
determines that trading thereon is restricted, or for any period during which an
emergency (as determined by the SEC) exists as a result of which the sale of
Portfolio shares is not reasonably practicable or as a result of which it is not
reasonably practicable for the Portfolio to fairly determine the value of its
net assets, or for such other periods as the SEC may by order permit for the
protection of shareholders.

DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS

Dividends and capital gain distributions from the Portfolio will be declared and
paid annually and will be reinvested in additional shares, at NAV, of the
Portfolio.

TAXES

Further information regarding the tax consequences of an investment in the
Portfolio is contained in the separate prospectuses and disclosure documents
issued by the participating insurance companies and accompanying this
Prospectus.

Financial Highlights

The table below describes the Portfolio's performance for the past five years.
It is intended to help you understand the financial performance of the
Portfolio's Class 1 shares. Certain information reflects financial results for a
single share of the Portfolio that was held throughout the periods shown. "Total
return" shows the rate that you would have earned (or lost) on an investment in
the Portfolio. Total returns do not reflect the effect of any administration
fees or sales charges imposed by the Contracts on their owners. Ernst & Young
LLP, independent auditors, have audited this information. Their report, along
with the Portfolio's financial statements, is included in the Fund's annual
report, which is available upon request.

The Fund and the Portfolio

OVERVIEW OF THE FUND

Seligman Portfolios, Inc. (the Fund) consists of 15 separate portfolios. This
Prospectus contains information about Seligman International Growth Portfolio
(the Portfolio).


The Portfolio is offering its shares only to separate accounts (Accounts) of
participating insurance companies to fund benefits of variable annuity and
variable life insurance contracts (Contracts). The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.


The Portfolio offers two classes of shares: Class 1 shares and Class 2 shares.
This Prospectus offers only Class 2 shares and is for use with Accounts that
make Class 2 shares available to Contract owners.

INVESTMENT OBJECTIVE

The Portfolio's objective is long-term capital appreciation.

PRINCIPAL INVESTMENT STRATEGIES

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

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

While the Portfolio may invest in companies of any size, it generally invests in
medium to large-sized companies in the principal international markets. It may
also invest in companies with lower market capitalization or in smaller regional
or emerging markets.

The Portfolio uses a top-down investment style when choosing securities to
purchase. This means the investment manager concentrates first on regional and
country allocations, then on industry sectors, followed by fundamental analysis
of individual companies. The Portfolio'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 pricing relative to earnings forecasts or other valuation
          criteria (e.g., return on equity)

     o    Quality management and equity ownership by executives

     o    A unique competitive advantage (e.g., market share, proprietary
          products)

     o    Market liquidity

     o    Potential for improvement in overall operations


                                      P-1
<PAGE>


The Portfolio generally sells a stock if its target price is reached, its
earnings are disappointing, its revenue growth slows, or its underlying
fundamentals deteriorate. The Portfolio may also sell a stock if the investment
manager believes that negative country or regional factors may affect a
company's outlook.

The Portfolio 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. Although the Portfolio normally invests in equity securities, the
Portfolio may invest up to 25% of its assets in preferred stock and investment
grade or comparable quality debt securities. The Portfolio 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.

The Portfolio may invest up to 15% of its 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 Portfolio may also purchase put options in an
attempt to hedge against a decline in the price of securities it holds in its
portfolio. A put option gives the Portfolio the right to sell an underlying
security at a particular price during a fixed period.


The Portfolio may change its principal strategies, except for stated fundamental
policies, if the Fund's Board of Directors believes doing so is consistent with
the Portfolio's objective. The Portfolio's objective and any fundamental
policies may be changed only with shareholder approval. If a change of objective
or fundamental policies is proposed, Contract owners will be asked to give
voting instructions to the participating insurance companies.

The Portfolio 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 Portfolio from achieving its objective.


There is no guarantee that the Portfolio will achieve its objective.

PRINCIPAL RISKS

Stock prices fluctuate. Therefore, as with any portfolio that invests in stocks,
the Portfolio'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 fluctuations, foreign
taxation, differences in financial reporting practices, and changes in political
conditions. There can be no assurance that the Portfolio's foreign investments
will present less risk than a portfolio of solely US securities.

The Portfolio 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
Portfolio's entire investment portfolio. However, a decline in the value of the
Portfolio's investments in one country may offset potential gains from
investments in another country.

The Portfolio 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.

Options or illiquid securities in the Portfolio's investment portfolio involve
higher risk and may subject the Portfolio to higher price volatility.

The Portfolio 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 Portfolio's expenses.


Due to differences of tax treatment and other considerations, there is a
possibility that the interests of various Contract owners who own shares of the
Portfolio may conflict. The Board of Directors monitors events in order to
identify any disadvantages or material irreconcilable conflicts and to determine
what action, if any, should be taken in response.


An investment in the Portfolio 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

Class 2 shares are newly offered and have no performance history. The
information below provides some indication of the risks of investing in the
Portfolio by showing how the performance of Class 1 shares of the Portfolio has
varied year to year, as well as how its performance compares to two widely-used
measures of performance. How the Portfolio has performed in the past, however,
is not necessarily an indication of how it will perform in the future.


Total returns will vary between Class 1 shares and Class 2 shares due to
different expenses of the two Classes. Class 1 annual total returns presented in
the bar chart and average annual total returns presented in the table do not
reflect the effect of the shareholder servicing and distribution (12b-1) fees
associated with Class 2 shares or the effect of any administration fees or sales
charges imposed by the Contracts on their owners. If these expenses were
included, the returns would be lower. Both the bar chart and table assume that
all dividends and capital gain distributions were reinvested.

MANAGEMENT OF THE FUND

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

J. & W. Seligman & Co. Incorporated (Seligman), 100 Park Avenue, New York, New
York 10017, is the manager of the Fund. Seligman provides investment management
services for the Portfolio, including making purchases and sales of securities
for the Portfolio, consistent with the Portfolio's investment objective and
strategies, and administers the Portfolio's business and other affairs.


Established in 1864, Seligman currently serves as manager to 20 US registered
investment companies, which offer more than 50 investment portfolios with
approximately $30 billion in assets as of March 31, 2000. Seligman also provides
investment management or advice to institutional or other accounts having an
aggregate value at March 31, 2000 of approximately $12 billion.

The Portfolio pays Seligman a management fee for its services, equal to a
percentage of the Portfolio's average daily net assets, as follows: 1.00% on
first $1 billion; .95% on next $1 billion; and .90% thereafter. For the year
ended December 31, 1999, the Portfolio paid Seligman a management fee equal to
an annual rate of 1.00% of its average daily net assets.

Prior to March 31, 2000, Henderson Investment Management Limited (HIML) served
as a subadviser to the Portfolio. HIML, established in 1984, is a wholly owned
subsidiary of Henderson plc, a United Kingdom corporation. For the year ended
December 31, 1999, Seligman paid HIML a fee for its services in respect of the
Portfolio based on the assets under HIML's supervision. This fee did not affect
the fees paid by the Portfolio.

Portfolio Management

The Portfolio is managed by Mr. Jack P. Chang, co-leader of Seligman's Global
Growth Team.

Mr. Chang joined Seligman on September 20, 1999 as a Managing Director. He is a
Vice President of the Fund. Prior to joining Seligman, Mr. Chang was a Senior
Vice President and Portfolio Manager at Putnam Investment Management since 1997.
Prior thereto, he was a Portfolio Manager with Columbia Management Company from
1993 to 1997, and a Senior Analyst and Portfolio Manager with Scudder, Stevens &
Clark from 1989 to 1993. Mr. Chang also co-manages the Global Growth Portfolio
of the Fund. Mr. Chang is also a Vice President of Seligman Global Fund Series,
Inc. and manages its Seligman International Growth Fund and co-manages its
Seligman Global Growth Fund.

Shareholder Information

PRICING OF FUND SHARES

When you buy or sell shares, you do so at the Portfolio's net asset value (NAV)
next calculated after your request is received by participating insurance
companies. If your purchase or sell request is received by participating
insurance companies by the close of regular trading on the New York Stock
Exchange (NYSE) (normally 4:00 p.m. Eastern time), it will be executed at the
Portfolio's NAV calculated as of the close of regular trading on the NYSE on
that day.

If your purchase or sell request is received by participating insurance
companies after the close of regular trading on the NYSE, your request will be
executed at the Portfolio's NAV calculated as of the close of regular trading on
the next NYSE trading day.

The NAV of the Portfolio is computed each day, Monday through Friday, on days
that the NYSE is open for trading. Securities owned by the Portfolio are valued
at current market prices. If reliable market prices are unavailable, securities
are valued in accordance with procedures approved by the Fund's Board of
Directors.

HOW TO PURCHASE AND SELL SHARES

The Portfolio is offering its shares only to Accounts of participating insurance
companies to fund benefits of the Contracts. The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.

An Account may sell all or any portion of the Portfolio shares that it holds at
any time at the next computed NAV per share, as described above. Portfolio
shares that are sold are entitled to any dividends that have been declared as
payable to record owners up to and including the day the sale is effected. There
is no charge. Payment of the sale price will normally be made within seven days
after receipt of such sale. In addition, the right to sell your shares may be
suspended and the date of payment of the sale price may be postponed for any
period during which the NYSE is closed (other than customary weekend and holiday
closings) or during which the Securities and Exchange Commission (SEC)
determines that trading thereon is restricted, or for any period during which an
emergency (as determined by the SEC) exists as a result of which the sale of
Portfolio shares is not reasonably practicable or as a result of which it is not
reasonably practicable for the Portfolio to fairly determine the value of its
net assets, or for such other periods as the SEC may by order permit for the
protection of shareholders.

SHAREHOLDER SERVICING AND DISTRIBUTION ARRANGEMENTS


Under a Rule 12b-1 plan adopted by the Fund with respect to the Portfolio, Class
2 shares pay an annual shareholder servicing and distribution (12b-1) fee of up
to 0.25% of average net assets. The Portfolio pays this fee to Seligman
Advisors, Inc., the principal underwriter of the Portfolio's shares. Seligman
Advisors uses this fee to make payments to participating insurance companies or
their affiliates for services that the participating insurance companies provide
to Contract owners of Class 2 shares, and for distribution related expenses.
Because these 12b-1 fees are paid out of the Portfolio's assets on an ongoing
basis, over time they will increase the cost of a Contract owner's investment
and may cost you more than other types of sales charges.



                                      P-5
<PAGE>


DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS

Dividends and capital gain distributions from the Portfolio will be declared and
paid annually and will be reinvested in additional shares, at NAV, of the
Portfolio. Dividends on Class 2 shares generally will be lower than dividends on
Class 1 shares as a result of 12b-1 fees. Capital gain distributions will be
paid in the same amount for each Class.

TAXES

Further information regarding the tax consequences of an investment in the
Portfolio is contained in the separate prospectuses and disclosure documents
issued by the participating insurance companies and accompanying this
Prospectus.

Financial Highlights


The table below describes the Portfolio's performance for the past five years.
It is intended to help you understand the financial performance of the
Portfolio's Class 1 shares. Class 2 shares are a newly offered Class, effective
May 1, 2000, so financial highlights are not available. Certain information
reflects financial results for a single share of the Portfolio that was held
throughout the periods shown. "Total return" shows the rate that you would have
earned (or lost) on an investment in the Portfolio. Total returns do not reflect
the effect of the shareholder servicing and distribution (12b-1) fees associated
with Class 2 shares or any administration fees or sales charges imposed by the
Contracts on their owners. Ernst & Young llp, independent auditors, have audited
this information. Their report, along with the Portfolio's financial statements,
is included in the Fund's annual report, which is available upon request.

The Fund and the Portfolio

OVERVIEW OF THE FUND

Seligman Portfolios, Inc. (the Fund) consists of 15 separate portfolios. This
Prospectus contains information about Seligman High-Yield Bond Portfolio (the
Portfolio).


The Portfolio is offering its shares only to separate accounts (Accounts) of
participating insurance companies to fund benefits of variable annuity and
variable life insurance contracts (Contracts). The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.


The Portfolio offers two classes of shares: Class 1 shares and Class 2 shares.
This Prospectus offers only Class 1 shares and is for use with Accounts that
make Class 1 shares available to Contract owners.


INVESTMENT OBJECTIVE

The Portfolio's objective is to produce maximum current income.


PRINCIPAL INVESTMENT STRATEGIES

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

The Portfolio has a fundamental policy that requires that, except for temporary
defensive purposes, it invest at least 80% of the value of its total assets in
high-yielding, income-producing corporate bonds.

The Portfolio invests in a diversified range of high-yield, high-risk, medium
and lower quality corporate bonds and notes. Generally, bonds and notes
providing the highest yield are unrated or carry lower ratings (Baa or lower by
Moody's Investors Service, or BBB or lower by Standard & Poor's Ratings
Services). The Portfolio may purchase restricted securities that may be offered
and sold only to "qualified institutional buyers" under Rule 144A of the
Securities Act of 1933 (Rule 144A Securities).

The Portfolio uses a bottom-up security selection process. This means the
investment manager concentrates first on individual company fundamentals, before
industry considerations. The investment manager then looks at the particular
bond characteristics of the securities considered for purchase. In selecting
individual securities, the investment manager looks to identify companies that
it believes display one or more of the following:

     o    Strong operating cash flow and margins

     o    Improving financial ratios (i.e., creditworthiness)

     o    Leadership in market share or other competitive advantage

     o    Superior management

     o    Attractive relative pricing

The Portfolio will generally sell a security if the investment manager believes
that the company displays deteriorating cash flows, an ineffective management
team, or an unattractive relative valuation.

The Portfolio may invest up to 20% of its total assets in a range of high-yield,
medium and lower quality corporate notes; short-term money market instruments,
including certificates of deposit of FDIC member banks having total assets of
more than $1 billion; bankers' acceptances and interest-bearing savings or time
deposits of such banks; prime commercial paper; securities issued, guaranteed,
or insured by the US Government, its agencies or instrumentalities; and other
income-producing cash items, including repurchase agreements.

The Portfolio may invest up to 15% of its net assets in illiquid securities
(i.e., securities that cannot be readily sold). Rule 144A Securities deemed to
be liquid by the investment manager are not included in this limitation. The
Portfolio may invest up to 10% of its total assets in debt securities of foreign
issuers. In accordance with its objective of producing


                                      P-1

<PAGE>


maximum current income, the Portfolio may invest up to 10% of its total assets
in preferred stock, including non-investment-grade preferred stock. While the
Portfolio favors cash-paying bonds over deferred pay securities, it may invest
in "zero-coupon" bonds (interest payments accrue until maturity) and
"pay-in-kind" bonds (interest payments are made in additional bonds).

The Portfolio may change its principal strategies, except for stated fundamental
policies, if the Fund's Board of Directors believes doing so is consistent with
the Portfolio's objective. The Portfolio's objective and any fundamental
policies may be changed only with shareholder approval. If a change of objective
or fundamental policies is proposed, Contract owners will be asked to give
voting instructions to the participating insurance companies.

The Portfolio 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 Portfolio from achieving its objective.


There is no guarantee that the Portfolio will acheive its objective.

PRINCIPAL RISKS

The Portfolio's net asset value, yield and total return will fluctuate with
fluctuations in the yield and market value of the individual securities held by
the Portfolio. The types of securities in which the Portfolio invests are
generally subject to higher volatility in yield and market value than securities
of higher quality. Factors that may affect the performance of the securities
held by the Portfolio are discussed below.

Higher-yielding, higher-risk, medium and lower quality corporate bonds and
notes, like the securities in which the Portfolio invests, are subject to
greater risk of loss of principal and income than higher-rated bonds and notes
and are considered to be predominantly speculative with respect to the issuer's
capacity to pay interest and repay principal.

An economic downturn could adversely impact issuers' ability to pay interest and
repay principal and could result in issuers' defaulting on such payments. The
value of the Portfolio's bonds and notes will be affected, like all fixed-income
securities, by market conditions relating to changes in prevailing interest
rates. However, the value of lower rated or unrated corporate bonds and notes is
also affected by investors' perceptions. When economic conditions appear to be
deteriorating, lower-rated or unrated corporate bonds and notes may decline in
market value due to investors' heightened concerns and perceptions over credit
quality.

Lower-rated and unrated corporate bonds and notes are traded principally by
dealers in the over-the-counter market. The market for these securities may be
less active and less liquid than for higher rated securities. Under adverse
market or economic conditions, the secondary market for these bonds and notes
could contract further, causing the Portfolio difficulties in valuing and
selling its securities.

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

"Zero-coupon" and "pay-in-kind" securities may be subject to greater
fluctuations in value because they tend to be more speculative than
income-bearing securities. Fluctuations in the market prices of these securities
owned by the Portfolio will result in corresponding fluctuations and volatility
in the net asset value of the shares of the Portfolio. Additionally, because
they do not pay current income, they will detract from the Portfolio's objective
of producing maximum current income.

The Portfolio 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 Portfolio's expenses.


Due to differences of tax treatment and other considerations, there is a
possibility that the interests of various Contract owners who own shares of the
Portfolio may conflict. The Board of Directors monitors events in order to
identify any disadvantages or material irreconcilable conflicts and to determine
what action, if any, should be taken in response.


An investment in the Portfolio 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 information below provides some indication of the risks of investing in the
Portfolio by showing how the performance of Class 1 shares of the Portfolio has
varied year to year, as well as how its performance compares to two widely-used
measures of performance. How the Portfolio has performed in the past, however,
is not necessarily an indication of how it will perform in the future.

Class 1 annual total returns presented in the bar chart and average annual total
returns presented in the table do not reflect the effect of any administration
fees or sales charges imposed by the Contracts on their owners. If these
expenses were included, the returns would be lower. Both the bar chart and table
assume that all dividends and capital gain distributions were reinvested.

Shareholder Information

PRICING OF FUND SHARES

When you buy or sell shares, you do so at the Portfolio's net asset value (NAV)
next calculated after your request is received by participating insurance
companies. If your purchase or sell request is received by participating
insurance companies by the close of regular trading on the New York Stock
Exchange (NYSE) (normally 4:00 p.m. Eastern time), it will be executed at the
Portfolio's NAV calculated as of the close of regular trading on the NYSE on
that day.

If your purchase or sell request is received by participating insurance
companies after the close of regular trading on the NYSE, your request will be
executed at the Portfolio's NAV calculated as of the close of regular trading on
the next NYSE trading day.

The NAV of the Portfolio is computed each day, Monday through Friday, on days
that the NYSE is open for trading. Securities owned by the Portfolio are valued
at current market prices. If reliable market prices are unavailable, securities
are valued in accordance with procedures approved by the Fund's Board of
Directors.


HOW TO PURCHASE AND SELL SHARES

The Portfolio is offering its shares only to Accounts of participating insurance
companies to fund benefits of the Contracts. The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.

An Account may sell all or any portion of the Portfolio shares that it holds at
any time at the next computed NAV per share, as described above. Portfolio
shares that are sold are entitled to any dividends that have been declared as
payable to record owners up to and including the day the sale is effected. There
is no charge. Payment of the sale price will normally be made within seven days
after receipt of such sale. In addition, the right to sell your shares may be
suspended and the date of payment of the sale price may be postponed for any
period during which the NYSE is closed (other than customary weekend and holiday
closings) or during which the Securities and Exchange Commission (SEC)
determines that trading thereon is restricted, or for any period during which an
emergency (as determined by the SEC) exists as a result of which the sale of
Portfolio shares is not reasonably practicable or as a result of which it is not
reasonably practicable for the Portfolio to fairly determine the value of its
net assets, or for such other periods as the SEC may by order permit for the
protection of shareholders.

DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS

Dividends and capital gain distributions from the Portfolio will be declared and
paid annually and will be reinvested in additional shares, at NAV, of the
Portfolio.


TAXES

Portfolio is contained in the separate prospectuses and disclosure documents
issued by the participating insurance companies and accompanying this
Prospectus.

Financial Highlights

The table below describes the Portfolio's performance for the period of the
Portfolio's operations. It is intended to help you understand the financial
performance of the Portfolio's Class 1 shares. Certain information reflects
financial results for a single share of the Portfolio that was held throughout
the periods shown. "Total return" shows the rate that you would have earned (or
lost) on an investment in the Portfolio. Total returns do not reflect the effect
of any administration fees or sales charges imposed by the Contracts on their
owners. Ernst & Young LLP, independent auditors, have audited this information.

The Fund and the Portfolio

OVERVIEW OF THE FUND


Seligman Portfolios, Inc. (the Fund) consists of 15 separateportfolios. This
Prospectus contains information about Seligman High-Yield Bond Portfolio (the
Portfolio).

The Portfolio is offering its shares only to separate accounts (Accounts) of
participating insurance companies to fund benefits of variable annuity and
variable life insurance contracts (Contracts). The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.


The Portfolio offers two classes of shares: Class 1 shares and Class 2 shares.
This Prospectus offers only Class 2 shares and is for use with Accounts that
make Class 2 shares available to Contract owners.

INVESTMENT OBJECTIVE

The Portfolio's objective is to produce maximum current income.

PRINCIPAL INVESTMENT STRATEGIES

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

The Portfolio has a fundamental policy that requires that, except for temporary
defensive purposes, it invest at least 80% of the value of its total assets in
high-yielding, income-producing corporate bonds.

The Portfolio invests in a diversified range of high-yield, high-risk, medium
and lower quality corporate bonds and notes. Generally, bonds and notes
providing the highest yield are unrated or carry lower ratings (Baa or lower by
Moody's Investors Service or BBB or lower by Standard & Poor's Ratings
Services). The Portfolio may purchase restricted securities that may be offered
and sold only to "qualified institutional buyers" under Rule 144A of the
Securities Act of 1933 (Rule 144A Securities).

The Portfolio uses a bottom-up security selection process. This means the
investment manager concentrates first on individual company fundamentals, before
industry considerations. The investment manager then looks at the particular
bond characteristics of the securities considered for purchase. In selecting
individual securities, the investment manager looks to identify companies that
it believes display one or more of the following:

     o    Strong operating cash flow and margins

     o    Improving financial ratios (i.e., creditworthiness)

     o    Leadership in market share or other competitive advantage

     o    Superior management

     o    Attractive relative pricing

The Portfolio will generally sell a security if the investment manager believes
that the company displays deteriorating cash flows, an ineffective management
team, or an unattractive relative valuation.

The Portfolio may invest up to 20% of its total assets in a range of high-yield,
medium and lower quality corporate notes; short-term money market instruments,
including certificates of deposit of FDIC member banks having total assets of
more than $1 billion; bankers' acceptances and interest-bearing savings or time
deposits of such banks; prime commercial paper; securities issued, guaranteed,
or insured by the US Government, its agencies or instrumentalities; and other
income-producing cash items, including repurchase agreements.


The Portfolio may invest up to 15% of its net assets in illiquid securities
(i.e., securities that cannot be readily sold). Rule 144A Securities deemed to
be liquid by the investment manager are not included in this limitation. The
Portfolio may invest up to 10% of its total assets in debt securities of foreign
issuers. In accordance with its objective of producing maximum current income,
the Portfolio may invest up to 10% of its total assets in preferred stock,
including non-


                                      P-1
<PAGE>

investment-grade preferred stock. While the Portfolio favors cash-paying bonds
over deferred pay securities, it may invest in "zero-coupon" bonds (interest
payments accrue until maturity) and "pay-in-kind" bonds (interest payments are
made in additional bonds).

The Portfolio may change its principal strategies, except for stated fundamental
policies, if the Fund's Board of Directors believes doing so is consistent with
the Portfolio's objective. The Portfolio's objective and any fundamental
policies may be changed only with shareholder approval. If a change of objective
or fundamental policies is proposed, Contract owners will be asked to give
voting instructions to the participating insurance companies.

The Portfolio 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 Portfolio from achieving its objective.


There is no guarantee that the Portfolio will achieve its objective.

PRINCIPAL RISKS

The Portfolio's net asset value, yield and total return will fluctuate with
fluctuations in the yield and market value of the individual securities held by
the Portfolio. The types of securities in which the Portfolio invests are
generally subject to higher volatility in yield and market value than securities
of higher quality. Factors that may affect the performance of the securities
held by the Portfolio are discussed below.

Higher-yielding, higher-risk, medium and lower quality corporate bonds and
notes, like the securities in which the Portfolio invests, are subject to
greater risk of loss of principal and income than higher-rated bonds and notes
and are considered to be predominantly speculative with respect to the issuer's
capacity to pay interest and repay principal.

An economic downturn could adversely impact issuers' ability to pay interest and
repay principal and could result in issuers' defaulting on such payments. The
value of the Portfolio's bonds and notes will be affected, like all fixed-income
securities, by market conditions relating to changes in prevailing interest
rates. However, the value of lower rated or unrated corporate bonds and notes is
also affected by investors' perceptions. When economic conditions appear to be
deteriorating, lower-rated or unrated corporate bonds and notes may decline in
market value due to investors' heightened concerns and perceptions over credit
quality.

Lower-rated and unrated corporate bonds and notes are traded principally by
dealers in the over-the-counter market. The market for these securities may be
less active and less liquid than for higher rated securities. Under adverse
market or economic conditions, the secondary market for these bonds and notes
could contract further, causing the Portfolio difficulties in valuing and
selling its securities.

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

"Zero-coupon" and "pay-in-kind" securities may be subject to greater
fluctuations in value because they tend to be more speculative than
income-bearing securities. Fluctuations in the market prices of these securities
owned by the Portfolio will result in corresponding fluctuations and volatility
in the net asset value of the shares of the Portfolio. Additionally, because
they do not pay current income, they will detract from the Portfolio's objective
of producing maximum current income.


The Portfolio 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 Portfolio's expenses.

Due to differences of tax treatment and other considerations, there is a
possibility that the interests of various Contract owners who own shares of the
Portfolio may conflict. The Board of Directors monitors events in order to
identify any disadvantages or material irreconcilable conflicts and to determine
what action, if any, should be taken in response.


An investment in the Portfolio 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

Class 2 shares are newly offered and have no performance history. The
information below provides some indication of the risks of investing in the
Portfolio by showing how the performance of Class 1 shares of the Portfolio has
varied year to year, as well as how its performance compares to two widely-used
measures of performance. How the Portfolio has performed in the past, however,
is not necessarily an indication of how it will perform in the future.


Total returns will vary between Class 1 shares and Class 2 shares due to
different expenses of the two Classes. Class 1 annual total returns presented in
the bar chart and average annual total returns presented in the table do not
reflect the effect of the shareholder servicing and distribution (12b-1) fees
associated with Class 2 shares or the effect of any administration fees or sales
charges imposed by the Contracts on their owners. If these expenses were
included, the returns would be lower. Both the bar chart and table assume that
all dividends and capital gain distributions were reinvested.

Shareholder Information

PRICING OF FUND SHARES

When you buy or sell shares, you do so at the Portfolio's net asset value (NAV)
next calculated after your request is received by participating insurance
companies. If your purchase or sell request is received by participating
insurance companies by the close of regular trading on the New York Stock
Exchange (NYSE) (normally 4:00 p.m. Eastern time), it will be executed at the
Portfolio's NAV calculated as of the close of regular trading on the NYSE on
that day.

If your purchase or sell request is received by participating insurance
companies after the close of regular trading on the NYSE, your request will be
executed at the Portfolio's NAV calculated as of the close of regular trading on
the next NYSE trading day.

The NAV of the Portfolio is computed each day, Monday through Friday, on days
that the NYSE is open for trading. Securities owned by the Portfolio are valued
at current market prices. If reliable market prices are unavailable, securities
are valued in accordance with procedures approved by the Fund's Board of
Directors.

HOW TO PURCHASE AND SELL SHARES

The Portfolio is offering its shares only to Accounts of participating insurance
companies to fund benefits of the Contracts. The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.

An Account may sell all or any portion of the Portfolio shares that it holds at
any time at the next computed NAV per share, as described above. Portfolio
shares that are sold are entitled to any dividends that have been declared as
payable to record owners up to and including the day the sale is effected. There
is no charge. Payment of the sale price will normally be made within seven days
after receipt of such sale. In addition, the right to sell your shares may be
suspended and the date of payment of the sale price may be postponed for any
period during which the NYSE is closed (other than customary weekend and holiday
closings) or during which the Securities and Exchange Commission (SEC)
determines that trading thereon is restricted, or for any period during which an
emergency (as determined by the SEC) exists as a result of which the sale of
Portfolio shares is not reasonably practicable or as a result of which it is not
reasonably practicable for the Portfolio to fairly determine the value of its
net assets, or for such other periods as the SEC may by order permit for the
protection of shareholders.


SHAREHOLDER SERVICING AND DISTRIBUTION ARRANGEMENTS

Under a Rule 12b-1 plan adopted by the Fund with respect to the Portfolio, Class
2 shares pay an annual shareholder servicing and distribution (12b-1) fee of up
to 0.25% of average net assets. The Portfolio pays this fee to Seligman
Advisors, Inc., the principal underwriter of the Portfolio's shares. Seligman
Advisors uses this fee to make payments to participating insurance companies or
their affiliates for services that the participating insurance companies provide
to Contract owners of Class 2 shares, and for distribution related expenses.
Because these 12b-1 fees are paid out of the Portfolio's assets on an ongoing
basis, over time they will increase the cost of a Contract owner's investment
and may cost you more than other types of sales charges.



                                      P-5

<PAGE>

DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS

Dividends and capital gain distributions from the Portfolio will be declared and
paid annually and will be reinvested in additional shares, at NAV, of the
Portfolio. Dividends on Class 2 shares generally will be lower than the
dividends on Class 1 shares as a result of 12b-1 fees. Capital gain
distributions will be paid in the same amount for each Class.

TAXES

Further information regarding the tax consequences of an investment in the
Portfolio is contained in the separate prospectuses and disclosure documents
issued by the participating insurance companies and accompanying this
Prospectus.

Financial Highlights


The table below describes the Portfolio's performance for the period of the
Portfolio's operations. It is intended to help you understand the financial
performance of the Portfolio's Class 1 shares. Class 2 shares are a newly
offered Class, effective May 1, 2000, so financial highlights are not available.
Certain information reflects financial results for a single share of the
Portfolio that was held throughout the periods shown. "Total return" shows the
rate that you would have earned (or lost) on an investment in the Portfolio.
Total returns do not reflect the effect of the shareholder servicing and
distribution (12b-1) fees associated with Class 2 shares or any administration
fees or sales charges imposed by the Contracts on their owners. Ernst & Young
LLP, independent auditors, have audited this information. Their report, along
with the Portfolio's financial statements, is included in the Fund's annual
report, which is available upon request.

The Fund and the Portfolio

OVERVIEW OF THE FUND

Seligman Portfolios, Inc. (the Fund) consists of 15 separate portfolios. This
Prospectus contains information about Seligman Income Portfolio (the Portfolio).


The Portfolio is offering its shares only to separate accounts (Accounts) of
participating insurance companies to fund benefits of variable annuity and
variable life insurance contracts (Contracts). The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.


The Portfolio offers two classes of shares: Class 1 shares and Class 2 shares.
This Prospectus offers only Class 1 shares and is for use with Accounts that
make Class 1 shares available to Contract owners.

INVESTMENT OBJECTIVES

The Portfolio's objectives are high current income consistent with what is
believed to be prudent risk of capital and the possibility of improvement in
income over time.

PRINCIPAL INVESTMENT STRATEGIES

The Portfolio uses the following principal strategies to seek its objectives:

The Portfolio invests at least 80% of its assets in income-producing securities.
The Portfolio has a fundamental policy that, at all times, it must invest at
least 25% of the value of its gross assets in cash, bonds and/or preferred
stocks.

Subject to these requirements, the Portfolio may invest in many different types
of securities. Income-producing securities in which the Portfolio may invest
include money market instruments, fixed-income securities (such as notes, bonds,
debentures, and preferred stock), US Government securities, collateralized
mortgage obligations, senior securities convertible into common stocks, common
stocks, and American Depositary Receipts (ADRs). ADRs are publicly traded
instruments generally issued by domestic banks or trust companies that represent
securities of foreign issuers. Securities are carefully selected in light of the
Portfolio's investment objectives are are diversified among many different types
of securities and market sectors.

The Portfolio allocates its assets between equity securities and fixed-income
securities. If equity valuations become excessive, then the Portfolio will
invest more of its assets in fixed-income securities.

Equity securities are chosen for purchase by the Portfolio using a bottom-up
stock selection approach. This means the investment manager concentrates on
individual company fundamentals, rather than on a particular industry. The
Portfolio maintains a disciplined investment process that focuses on downside
risk as well as upside potential. The Portfolio seeks to purchase strong,
well-managed companies, generally large US companies, which have the potential
for solid earnings growth and dividend increases. The investment manager looks
to identify companies that it believes offer attractive dividend yields relative
to the market and, typically, that display relatively low valuations.

Fixed-income securities are chosen for purchase by the Portfolio using a method
that combines macro analysis of the fixed-income with fundamental research into
individual securities, customized by market sector. This means that the
investment manager considers the trends in the fixed-income market and evaluates
the long-term trends in interest rates, and then selects individual securities
for the Portfolio based on its evaluation of each security's particular
characteristics (for example, duration, yield, quality, relative value) and
total return opportunities.

The Portfolio may invest up to 15% of its net assets in illiquid securities
(i.e., securities that cannot be readily sold) and may invest up to 10% of its
total assets directly in foreign securities. The limit on foreign securities
does not include ADRs, or commercial paper and certificates of deposit issued by
foreign banks. The Portfolio generally does not invest a significant amount, if
any, in illiquid or foreign securities.


                                      P-1
<PAGE>



The Portfolio may change its principal strategies, except for stated fundamental
policies, if the Fund's Board of Directors believes doing so is consistent with
the Portfolio's objectives. The Portfolio's objectives and any fundamental
policies may be changed only with shareholder approval. If a change of objective
or fundamental policies is proposed, Contract owners will be asked to give
voting instructions to the participating insurance companies.

The Portfolio 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 Portfolio from achieving its objectives.


There is no guarantee that the Portfolio will achieve its objectives.

PRINCIPAL RISKS

A significant portion of the Portfolio's assets is generally invested in common
stocks. Stock prices fluctuate. Therefore, as with any portfolio that invests in
stocks, the Portfolio's net assets value will fluctuate, especially in the short
term. 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.

While the Portfolio maintains exposure to varied industry sectors over the
longer term, it may invest more heavily in certain industries believed to offer
good investment opportunities. To the extent that an industry in which the
Portfolio is invested falls out of favor, the Portfolio's performance may be
negatively affected.


Stocks of large US companies, like those in which the Portfolio may invest, have
experienced an extended period of strong performance. However, if investor
sentiment changes, the value of large company stocks may decline. This could
have an adverse effect on the Portfolio's yield, net asset value, and total
return.


The portion of the Portfolio's assets that are invested in fixed-income
securities will be subject to interest rate risk and credit risk, as discussed
below.

Changes in market interest rates will affect the value of the fixed-income
securities held by the Portfolio. In general, the market value of fixed-income
securities moves in the opposite direction of interest rates: the market value
decreases when interest rates rise and increases when interest rates fall.
Long-term securities are generally more sensitive to changes in interest rates,
and, therefore, subject to a greater degree of market price volatility. Changes
in the value of the fixed-income securities held by the Portfolio may affect the
Portfolio's net asset value. The extent to which the Portfolio is affected will
depend on the percentage of the Portfolio's assets that is invested in
fixed-income securities and the duration of the securities held.

A fixed-income security could deteriorate in quality to such an extent that its
rating is downgraded or its market value declines relative to comparable
securities. Credit risk also includes the risk that an issuer of a security
would be unable to make interest and principal payments. To the extent the
Portfolio holds securities that are downgraded, or default on payment, its
performance could be negatively affected.

Fixed-income securities, like those in which the Portfolio invests, are traded
principally by dealers in the over-the-counter market. The Portfolio's ability
to sell securities it holds is dependent on the willingness and ability of
market participants to provide bids that reflect current market levels. Adverse
market conditions could result in a lack of liquidity by reducing the number of
ready buyers.

The Portfolio 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 Portfolio's expenses.


Due to differences of tax treatment and other considerations, there is a
possibility that the interests of various Contract owners who own shares of the
Portfolio may conflict. The Board of Directors monitors events in order to
identify any disadvantages or material irreconcilable conflicts and to determine
what action, if any, should be taken in response.


An investment in the Portfolio 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 information below provides some indication of the risks of investing in the
Portfolio by showing how the performance of Class 1 shares of the Portfolio has
varied year to year, as well as how its performance compares to three
widely-used measures of performance. How the Portfolio has performed in the
past, however, is not necessarily an indication of how it will perform in the
future.

Class 1 annual total returns presented in the bar chart and average annual total
returns presented in the table do not reflect the effect of the any
administration fees or sales charges imposed by the Contracts on their owners.
If these expenses were included, the returns would be lower. Both the bar chart
and table assume that all dividends and capital gain distributions were
reinvested.

Shareholder Information

PRICING OF FUND SHARES

When you buy or sell shares, you do so at the Portfolio's net asset value (NAV)
next calculated after your request is received by participating insurance
companies. If your purchase or sell request is received by participating
insurance companies by the close of regular trading on the New York Stock
Exchange (NYSE) (normally 4:00 p.m. Eastern time), it will be executed at the
Portfolio's NAV calculated as of the close of regular trading on the NYSE on
that day.

If your purchase or sell request is received by participating insurance
companies after the close of regular trading on the NYSE, your request will be
executed at the Portfolio's NAV calculated as of the close of regular trading on
the next NYSE trading day.

The NAV of the Portfolio is computed each day, Monday through Friday, on days
that the NYSE is open for trading. Securities owned by the Portfolio are valued
at current market prices. If reliable market prices are unavailable, securities
are valued in accordance with procedures approved by the Fund's Board of
Directors.

HOW TO PURCHASE AND SELL SHARES

The Portfolio is offering its shares only to Accounts of participating insurance
companies to fund benefits of the Contracts. The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.

An Account may sell all or any portion of the Portfolio shares that it holds at
any time at the next computed NAV per share, as described above. Portfolio
shares that are sold are entitled to any dividends that have been declared as
payable to record owners up to and including the day the sale is effected. There
is no charge. Payment of the sale price will normally be made within seven days
after receipt of such sale. In addition, the right to sell your shares may be
suspended and the date of payment of the sale price may be postponed for any
period during which the NYSE is closed (other than customary weekend and holiday
closings) or during which the Securities and Exchange Commission (SEC)
determines that trading thereon is restricted, or for any period during which an
emergency (as determined by the SEC) exists as a result of which the sale of
Portfolio shares is not reasonably practicable or as a result of which it is not
reasonably practicable for the Portfolio to fairly determine the value of its
net assets, or for such other periods as the SEC may by order permit for the
protection of shareholders.

The Fund and the Portfolio

OVERVIEW OF THE FUND

Seligman Portfolios, Inc. (the Fund) consists of 15 separate portfolios. This
Prospectus contains information about Seligman Income Portfolio (the Portfolio).


The Portfolio is offering its shares only to separate accounts (Accounts) of
participating insurance companies to fund benefits of variable annuity and
variable life insurance contracts (Contracts). The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.


The Portfolio offers two classes of shares: Class 1 shares and Class 2 shares.
This Prospectus offers only Class 2 shares and is for use with Accounts that
make Class 2 shares available to Contract owners.

INVESTMENT OBJECTIVES

The Portfolio's objectives are high current income consistent with what is
believed to be prudent risk of capital and the possibility of improvement in
income over time.

PRINCIPAL INVESTMENT STRATEGIES

The Portfolio uses the following principal strategies to seek its objectives:

The Portfolio invests at least 80% of its assets in income-producing securities.
The Portfolio has a fundamental policy that, at all times, it must invest at
least 25% of the value of its gross assets in cash, bonds and/or preferred
stocks.

Subject to these requirements, the Portfolio may invest in many different types
of securities. Income-producing securities in which the Portfolio may invest
include money market instruments, fixed-income securities (such as notes, bonds,
debentures, and preferred stock), US Government securities, collateralized
mortgage obligations, senior securities convertible into common stocks, common
stocks, and American Depositary Receipts (ADRs). ADRs are publicly traded
instruments generally issued by domestic banks or trust companies that represent
securities of foreign issuers. Securities are carefully selected in light of the
Portfolio's investment objectives are are diversified among many different types
of securities and market sectors.

The Portfolio allocates its assets between equity securities and fixed-income
securities. If equity valuations become excessive, then the Portfolio will
invest more of its assets in fixed-income securities.

Equity securities are chosen for purchase by the Portfolio using a bottom-up
stock selection approach. This means the investment manager concentrates on
individual company fundamentals, rather than on a particular industry. The
Portfolio maintains a disciplined investment process that focuses on downside
risk as well as upside potential. The Portfolio seeks to purchase strong,
well-managed companies, generally large US companies, which have the potential
for solid earnings growth and dividend increases. The investment manager looks
to identify companies that it believes offer attractive dividend yields relative
to the market and, typically, that display relatively low valuations.

Fixed-income securities are chosen for purchase by the Portfolio using a method
that combines macro analysis of the fixed-income with fundamental research into
individual securities, customized by market sector. This means that the
investment manager considers the trends in the fixed-income market and evaluates
the long-term trends in interest rates, and then selects individual securities
for the Portfolio based on its evaluation of each security's particular
characteristics (for example, duration, yield, quality, relative value) and
total return opportunities.

The Portfolio may invest up to 15% of its net assets in illiquid securities
(i.e., securities that cannot be readily sold) and may invest up to 10% of its
total assets directly in foreign securities. The limit on foreign securities
does not include ADRs, or commercial paper and certificates of deposit issued by
foreign banks. The Portfolio generally does not invest a significant amount, if
any, in illiquid or foreign securities.


                                       P-1
<PAGE>


The Portfolio may change its principal strategies, except for stated fundamental
policies, if the Fund's Board of Directors believes doing so is consistent with
the Portfolio's objectives. The Portfolio's objectives and any fundamental
policies may be changed only with shareholder approval. If a change of objective
or fundamental policies is proposed, Contract owners will be asked to give
voting instructions to the participating insurance companies.

The Portfolio 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 Portfolio from achieving its objectives.


There is no guarantee that the Portfolio will achieve its objectives.

PRINCIPAL RISKS

A significant portion of the Portfolio's assets is generally invested in common
stocks. Stock prices fluctuate. Therefore, as with any portfolio that invests in
stocks, the Portfolio's net assets value will fluctuate, especially in the short
term. 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.

While the Portfolio maintains exposure to varied industry sectors over the
longer term, it may invest more heavily in certain industries believed to offer
good investment opportunities. To the extent that an industry in which the
Portfolio is invested falls out of favor, the Portfolio's performance may be
negatively affected.


Stocks of large US companies, like those in which the Portfolio may invest, have
experienced an extended period of strong performance. However, if investor
sentiment changes, the value of large company stocks may decline. This could
have an adverse effect on the Portfolio's yield, net asset value, and total
return.


The Portion of the Portfolio's assets that are invested in fixed-income
securities will be subject to interest rate risk and credit risk, as discussed
below.

Changes in market interest rates will affect the value of the fixed-income
securities held by the Portfolio. In general, the market value of fixed-income
securities moves in the opposite direction of interest rates: the market value
decreases when interest rates rise and increases when interest rates fall.
Long-term securities are generally more sensitive to changes in interest rates,
and, therefore, subject to a greater degree of market price volatility. Changes
in the value of the fixed-income securities held by the Portfolio may affect the
Portfolio's net asset value. The extent to which the Portfolio is affected will
depend on the percentage of the Portfolio's assets that is invested in
fixed-income securities and the duration of the securities held.

A fixed-income security could deteriorate in quality to such an extent that its
rating is downgraded or its market value declines relative to comparable
securities. Credit risk also includes the risk that an issuer of a security
would be unable to make interest and principal payments. To the extent the
Portfolio holds securities that are downgraded, or default on payment, its
performance could be negatively affected.

Fixed-income securities, like those in which the Portfolio invests, are traded
principally by dealers in the over-the-counter market. The Portfolio's ability
to sell securities it holds is dependent on the willingness and ability of
market participants to provide bids that reflect current market levels. Adverse
market conditions could result in a lack of liquidity by reducing the number of
ready buyers.

The Portfolio 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 Portfolio's expenses.


Due to differences of tax treatment and other considerations, there is a
possibility that the interests of various Contract owners who own shares of the
Portfolio may conflict. The Board of Directors monitors events in order to
identify any disadvantages or material irreconcilable conflicts and to determine
what action, if any, should be taken in response.


An investment in the Portfolio 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


Class 2 shares are newly offered and have no performance history. The
information below provides some indication of the risks of investing in the
Portfolio by showing how the performance of Class 1 shares of the Portfolio has
varied year to year, as well as how its performance compares to three
widely-used measures of performance. How the Portfolio has performed in the
past, however, is not necessarily an indication of how it will perform in the
future.

Total returns will vary between Class 1 shares and Class 2 shares due to
different expenses of the two Classes. Class 1 annual total returns presented in
the bar chart and average annual total returns presented in the table do not
reflect the effect of the shareholder servicing and distribution (12b-1) fees
associated with Class 2 shares or the effect of any administration fees or sales
charges imposed by the Contracts on their owners. If these expenses were
included, the returns would be lower. Both the bar chart and table assume that
all dividends and capital gain distributions were reinvested.

Shareholder Information

PRICING OF FUND SHARES

When you buy or sell shares, you do so at the Portfolio's net asset value (NAV)
next calculated after your request is received by participating insurance
companies. If your purchase or sell request is received by participating
insurance companies by the close of regular trading on the New York Stock
Exchange (NYSE) (normally 4:00 p.m. Eastern time), it will be executed at the
Portfolio's NAV calculated as of the close of regular trading on the NYSE on
that day.

If your purchase or sell request is received by participating insurance
companies after the close of regular trading on the NYSE, your request will be
executed at the Portfolio's NAV calculated as of the close of regular trading on
the next NYSE trading day.

The NAV of the Portfolio is computed each day, Monday through Friday, on days
that the NYSE is open for trading. Securities owned by the Portfolio are valued
at current market prices. If reliable market prices are unavailable, securities
are valued in accordance with procedures approved by the Fund's Board of
Directors.

HOW TO PURCHASE AND SELL SHARES

The Portfolio is offering its shares only to Accounts of participating insurance
companies to fund benefits of the Contracts. The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.

An Account may sell all or any portion of the Portfolio shares that it holds at
any time at the next computed NAV per share, as described above. Portfolio
shares that are sold are entitled to any dividends that have been declared as
payable to record owners up to and including the day the sale is effected. There
is no charge. Payment of the sale price will normally be made within seven days
after receipt of such sale. In addition, the right to sell your shares may be
suspended and the date of payment of the sale price may be postponed for any
period during which the NYSE is closed (other than customary weekend and holiday
closings) or during which the Securities and Exchange Commission (SEC)
determines that trading thereon is restricted, or for any period during which an
emergency (as determined by the SEC) exists as a result of which the sale of
Portfolio shares is not reasonably practicable or as a result of which it is not
reasonably practicable for the Portfolio to fairly determine the value of its
net assets, or for such other periods as the SEC may by order permit for the
protection of shareholders.

SHAREHOLDER SERVICING AND DISTRIBUTION ARRANGEMENTS


Under a Rule 12b-1 plan adopted by the Fund with respect to the Portfolio, Class
2 shares pay an annual shareholder servicing and distribution (12b-1) fee of up
to 0.25% of average net assets. The Portfolio pays this fee to Seligman
Advisors, Inc., the principal underwriter of the Portfolio's shares. Seligman
Advisors uses this fee to make payments to participating insurance companies or
their affiliates for services that the participating insurance companies provide
to Contract owners of Class 2 shares, and for distribution related expenses.
Because these 12b-1 fees are paid out of the Portfolio's assets on an ongoing
basis, over time they will increase the cost of a Contract owner's investment
and may cost you more than other types of sales charges.


                                       P-5
<PAGE>

DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS


Dividends and capital gain distributions from the Portfolio will be declared and
paid annually and will be reinvested in additional shares, at NAV, of the
Portfolio. Dividends on Class 2 shares generally will be lower than the
dividends on Class 1 shares as a result of 12b-1 fees. Capital gain
distributions will be paid in the same amount for each Class.


TAXES

Further information regarding the tax consequences of an investment in the
Portfolio is contained in the separate prospectuses and disclosure documents
issued by the participating insurance companies and accompanying this
Prospectus.

Financial Highlights


The table below describes the Portfolio's performance for the past five years.
It is intended to help you understand the financial performance of the
Portfolio's Class 1 shares. Class 2 shares are a newly offered Class, effective
May 1, 2000, so financial highlights are not available. Certain information
reflects financial results for a single share of the Portfolio that was held
throughout the periods shown. "Total return" shows the rate that you would have
earned (or lost) on an investment in the Portfolio. Total returns do not reflect
the effect of the shareholder servicing and distribution (12b-1) fees associated
with Class 2 shares or any administration fees or sales charges imposed by the
Contracts on their owners. Ernst & Young llp, independent auditors, have audited
this information. Their report, along with the Portfolio's financial statements,
is included in the Fund's annual report, which is available upon request.

The Fund and the Portfolio

OVERVIEW OF THE FUND

Seligman Portfolios, Inc. (the Fund) consists of 15 separate portfolios. This
Prospectus contains information about Seligman Large-Cap Growth Portfolio (the
Portfolio).


The Portfolio is offering its shares only to separate accounts (Accounts) of
participating insurance companies to fund benefits of variable annuity and
variable life insurance contracts (Contracts). The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.


The Portfolio offers two classes of shares: Class 1 shares and Class 2 shares.
This Prospectus offers only Class 1 shares and is for use with Accounts that
make Class 1 shares available to Contract owners.


INVESTMENT OBJECTIVE

The Portfolio's objective is longer-term growth in capital value.

PRINCIPAL INVESTMENT STRATEGIES

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

Generally, the Portfolio invests primarily in the common stock of large US
companies, selected for their growth prospects. The investment manager chooses
common stocks for the Portfolio using both quantitative and fundamental
analysis. This means the investment manager first screens companies for past
growth in sales and earnings, as well as a strong balance sheet. The investment
manager favors a low ratio of debt to total capital. In selecting individual
securities for investment, the investment manager then looks to identify large
companies that it believes display one or more of the following:

     o    Proven track record

     o    Strong management

     o    Multiple product lines

     o    Potential for improvement in overall operations (a catalyst for growth
          in revenues and/or earnings)

     o    Positive supply and demand outlook for its industry

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

Large Companies:

Companies with market
capitalizations, at the time
of purchase by the
Portfolio, of $5 billion or
more.

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

The investment manager also looks at the forecasted earnings of a company to
determine if it has the potential for above-average growth.

The Portfolio will generally sell a stock when the investment manager believes
that the company or industry fundamentals have deteriorated or the company's
catalyst for growth is already reflected in the stock's price (i.e., the stock
is fully valued).


Although the Portfolio generally concentrates its investments in common stocks,
it may also invest in preferred stocks, securities convertible into common
stocks, common stock rights or warrants, and debt securities if the investment
manager believes they offer opportunities for growth in capital value.


The Portfolio may invest up to 15% of its net assets in illiquid securities
(i.e., securities that cannot be readily sold) and


                                      P-1

<PAGE>


may invest up to 10% of its total assets directly in foreign securities. The
Portfolio generally does not invest a significant amount, if any, in illiquid or
foreign securities.


The Portfolio may change its principal strategies, except for stated fundamental
policies, if the Fund's Board of Directors believes doing so is consistent with
the Portfolio's objective. The Portfolio's objective and any fundamental
policies may be changed only with shareholder approval. If a change of objective
or fundamental policies is proposed, Contract owners will be asked to give
voting instructions to the participating insurance companies.

The Portfolio 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 Portfolio from achieving its objective.

The Fund's Board of Directors may change the parameters by which "large
companies" are defined if it concludes such a change is appropriate.


There is no guarantee that the Portfolio will achieve its objective.


PRINCIPAL RISKS

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

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

The Portfolio may not invest more than 25% of its total assets in securities of
companies in any one industry. The Portfolio may, however, invest more heavily
in certain industries believed to offer good investment opportunities. If an
industry in which the Portfolio is invested falls out of favor, the Portfolio's
performance may be negatively affected.

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

The Portfolio 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 Portfolio's expenses.


Due to differences of tax treatment and other considerations, there is a
possibility that the interests of various Contract owners who own shares of the
Portfolio may conflict. The Board of Directors monitors events in order to
identify any disadvantages or material irreconcilable conflicts and to determine
what action, if any, should be taken in response.


An investment in the Portfolio 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 Portfolio commenced operations on May 1, 1999 and has not completed a full
calendar year's performance. Therefore, no performance information is provided
for the Portfolio.

MANAGEMENT OF THE FUND

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

J. & W. Seligman & Co. Incorporated (Seligman), 100 Park Avenue, New York, New

strategies, and administers the Portfolio's business and other affairs.

investment management or advice to institutional or other accounts having an
aggregate value at March 31, 2000 of approximately $12 billion.

first $1 billion; .65% on next $1 billion; and .60% therafter. For the period
ended December 31, 1999, the Portfolio paid Seligman a management fee equal to
an annual rate of .70% of its average daily net assets.

Shareholder Information

PRICING OF FUND SHARES

When you buy or sell shares, you do so at the Portfolio's net asset value (NAV)
next calculated after your request is received by participating insurance
companies. If your purchase or sell request is received by participating
insurance companies by the close of regular trading on the New York Stock
Exchange (NYSE) (normally 4:00 p.m. Eastern time), it will be executed at the
Portfolio's NAV calculated as of the close of regular trading on the NYSE on
that day.

If your purchase or sell request is received by participating insurance
companies after the close of regular trading on the NYSE, your request will be
executed at the Portfolio's NAV calculated as of the close of regular trading on
the next NYSE trading day.

The NAV of the Portfolio is computed each day, Monday through Friday, on days
that the NYSE is open for trading. Securities owned by the Portfolio are valued
at current market prices. If reliable market prices are unavailable, securities
are valued in accordance with procedures approved by the Fund's Board of
Directors.


HOW TO PURCHASE AND SELL SHARES

The Portfolio is offering its shares only to Accounts of participating insurance
companies to fund benefits of the Contracts. The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.

An Account may sell all or any portion of the Portfolio shares that it holds at
any time at the next computed NAV per share, as described above. Portfolio
shares that are sold are entitled to any dividends that have been declared as
payable to record owners up to and including the day the sale is effected. There
is no charge. Payment of the sale price will normally be made within seven days
after receipt of such sale. In addition, the right to sell your shares may be
suspended and the date of payment of the sale price may be postponed for any
period during which the NYSE is closed (other than customary weekend and holiday
closings) or during which the Securities and Exchange Commission (SEC)
determines that trading thereon is restricted, or for any period during which an
emergency (as determined by the SEC) exists as a result of which the sale of
Portfolio shares is not reasonably practicable or as a result of which it is not
reasonably practicable for the Portfolio to fairly determine the value of its
net assets, or for such other periods as the SEC may by order permit for the
protection of shareholders.


DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS

Dividends and capital gain distributions from the Portfolio will be declared and
paid annually and will be reinvested in additional shares, at NAV, of the
Portfolio.


TAXES

Further information regarding the tax consequences of an investment in the
Portfolio is contained in the separate prospectuses and disclosure documents
issued by the participating insurance companies and accompanying this
Prospectus.

The Fund and the Portfolio

OVERVIEW OF THE FUND

Seligman Portfolios, Inc. (the Fund) consists of 15 separate portfolios. This
Prospectus contains information about Seligman Large-Cap Growth Portfolio (the
Portfolio).


The Portfolio is offering its shares only to separate accounts (Accounts) of
participating insurance companies to fund benefits of variable annuity and
variable life insurance contracts (Contracts). The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.


The Portfolio offers two classes of shares: Class 1 shares and Class 2 shares.
This Prospectus offers only Class 2 shares and is for use with Accounts that
make Class 2 shares available to Contract owners.

INVESTMENT OBJECTIVE

The Portfolio's objective is longer-term growth in capital value.

PRINCIPAL INVESTMENT STRATEGIES

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

Generally, the Portfolio invests primarily in the common stock of large US
companies, selected for their growth prospects. The investment manager chooses
common stocks for the Portfolio using both quantitative and fundamental
analysis. This means the investment manager first screens companies for past
growth in sales and earnings, as well as a strong balance sheet. The investment
manager favors a low ratio of debt to total capital. In selecting individual
securities for investment, the investment manager then looks to identify large
companies that it believes display one or more of the following:

- ------------------------------------------
Large Companies:

Companies with market capitalizations,
at the time of purchase by the Portfolio,
of $5 billion or more.
- ------------------------------------------

     o    Proven track record

     o    Strong management

     o    Multiple product lines

     o    Potential for improvement in overall operations (a catalyst for growth
          in revenues and/or earnings)

     o    Positive supply and demand outlook for its industry

The investment manager also looks at the forecasted earnings of a company to
determine if it has the potential for above-average growth.

The Portfolio will generally sell a stock when the investment manager believes
that the company or industry fundamentals have deteriorated or the company's
catalyst for growth is already reflected in the stock's price (i.e., the stock
is fully valued).

Although the Portfolio generally concentrates its investments in common stocks,
it may also invest in preferred stocks, securities convertible into common
stocks, common stock rights or warrants, and debt securities if the investment
manager believes they offer opportunities for growth in capital value.

The Portfolio may invest up to 15% of its net assets in illiquid securities
(i.e., securities that cannot be readily sold) and may invest up to 10% of its
total assets directly in foreign securities. The Portfolio generally does not
invest a significant amount, if any, in illiquid or foreign securities.


                                      P-1
<PAGE>



The Portfolio may change its principal strategies, except for stated fundamental
policies, if the Fund's Board of Directors believes doing so is consistent with
the Portfolio's objective. The Portfolio's objective and any fundamental
policies may be changed only with shareholder approval. If a change of objective
or fundamental policies is proposed, Contract owners will be asked to give
voting instructions to the participating insurance companies.

The Portfolio 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 Portfolio from achieving its objective.

The Fund's Board of Directors may change the parameters by which "large
companies" are defined if it concludes such a change is appropriate.


There is no guarantee that the Portfolio will achieve its objective.

PRINCIPAL RISKS

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

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

The Portfolio may not invest more than 25% of its total assets in securities of
companies in any one industry. The Portfolio may, however, invest more heavily
in certain industries believed to offer good investment opportunities. If an
industry in which the Portfolio is invested falls out of favor, the Portfolio's
performance may be negatively affected.

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

The Portfolio 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 Portfolio's expenses.


Due to differences of tax treatment and other considerations, there is a
possibility that the interests of various Contract owners who own shares of the
Portfolio may conflict. The Board of Directors monitors events in order to
identify any disadvantages or material irreconcilable conflicts and to determine
what action, if any, should be taken in response.


An investment in the Portfolio 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 Portfolio commenced operations on May 1, 1999 and has not completed a full
calendar year of performance. Therefore, no performance information is provided
for the Portfolio.

MANAGEMENT OF THE FUND

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

first $1 billion; .65% on next $1 billion; and .60% therafter. For the period
ended December 31, 1999, the Portfolio paid Seligman a management fee equal to
an annual rate of .70% of its average daily net assets.

Shareholder Information

PRICING OF FUND SHARES

When you buy or sell shares, you do so at the Portfolio's net asset value (NAV)
next calculated after your request is received by participating insurance
companies. If your purchase or sell request is received by participating
insurance companies by the close of regular trading on the New York Stock
Exchange (NYSE) (normally 4:00 p.m. Eastern time), it will be executed at the
Portfolio's NAV calculated as of the close of regular trading on the NYSE on
that day.

If your purchase or sell request is received by participating insurance
companies after the close of regular trading on the NYSE, your request will be
executed at the Portfolio's NAV calculated as of the close of regular trading on
the next NYSE trading day.

The NAV of the Portfolio is computed each day, Monday through Friday, on days
that the NYSE is open for trading. Securities owned by the Portfolio are valued
at current market prices. If reliable market prices are unavailable, securities
are valued in accordance with procedures approved by the Fund's Board of
Directors.

HOW TO PURCHASE AND SELL SHARES

The Portfolio is offering its shares only to Accounts of participating insurance
companies to fund benefits of the Contracts. The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.

An Account may sell all or any portion of the Portfolio shares that it holds at
any time at the next computed NAV per share, as described above. Portfolio
shares that are sold are entitled to any dividends that have been declared as
payable to record owners up to and including the day the sale is effected. There
is no charge. Payment of the sale price will normally be made within seven days
after receipt of such sale. In addition, the right to sell your shares may be
suspended and the date of payment of the sale price may be postponed for any
period during which the NYSE is closed (other than customary weekend and holiday
closings) or during which the Securities and Exchange Commission (SEC)
determines that trading thereon is restricted, or for any period during which an
emergency (as determined by the SEC) exists as a result of which the sale of
Portfolio shares is not reasonably practicable or as a result of which it is not
reasonably practicable for the Portfolio to fairly determine the value of its
net assets, or for such other periods as the SEC may by order permit for the
protection of shareholders.


SHAREHOLDER SERVICING AND DISTRIBUTION ARRANGEMENTS

Under a Rule 12b-1 plan adopted by the Fund with respect to the Portfolio, Class
2 shares pay an annual shareholder servicing and distribution (12b-1) fee of up
to 0.25% of average net assets. The Portfolio pays this fee to Seligman
Advisors, Inc., the principal underwriter of the Portfolio's shares. Seligman
Advisors uses this fee to make payments to participating insurance companies or
their affiliates for services that the participating insurance companies provide
to Contract owners of Class 2 shares, and for distribution related expenses.
Because these 12b-1 fees are paid out of the Portfolio's assets on an ongoing
basis, over time they will increase the cost of a Contract owner's investment
and may cost you more than other types of sales charges.



                                      P-4
<PAGE>


DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS

Dividends and capital gain distributions from the Portfolio will be declared and
paid annually and will be reinvested in additional shares, at NAV, of the
Portfolio. Dividends on Class 2 shares generally will be lower than the
dividends on Class 1 shares as a result of 12b-1 fees. Capital gain
distributions will be paid in the same amount for each Class.

TAXES

Further information regarding the tax consequences of an investment in the
Portfolio is contained in the separate prospectuses and disclosure documents
issued by the participating insurance companies and accompanying this
Prospectus.

Financial Highlights


The table below describes the Portfolio's performance for the period of the
Portfolio's operations. It is intended to help you understand the financial
performance of the Portfolio's Class 1 shares. Class 2 shares are a newly
offered Class, effective May 1, 2000, so financial highlights are not available.
Certain information reflects financial results for a single share of the
Portfolio that was held throughout the period shown. "Total return" shows the
rate that you would have earned (or lost) on an investment in the Portfolio.
Total returns do not reflect the effect of the shareholder servicing and
distribution (12b-1) fees associated with Class 2 shares or any administration
fees or sales charges imposed by the Contracts on their owners. Ernst & Young
LLP, independent auditors, have audited this information. Their report, along
with the Portfolio's financial statements, is included in the Fund's annual

The Fund and the Portfolio

OVERVIEW OF THE FUND

Seligman Portfolios, Inc. (the Fund) consists of 15 separate portfolios. This
Prospectus contains information about Seligman Large-Cap Value Portfolio (the
Portfolio).


The Portfolio is offering its shares only to separate accounts (Accounts) of
participating insurance companies to fund benefits of variable annuity and
variable life insurance contracts (Contracts). The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.


The Portfolio offers two classes of shares: Class 1 shares and Class 2 shares.
This Prospectus offers only Class 1 shares and is for use with Accounts that
make Class 1 shares available to Contract owners.


INVESTMENT OBJECTIVE

The Portfolio's objective is long-term capital appreciation.


PRINCIPAL INVESTMENT STRATEGIES

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

The Portfolio generally invests at least 65% of its total assets in the common
stocks of "value" companies with large market capitalization ($2 billion or
more) at the time of purchase by the Portfolio.

The Portfolio uses a bottom-up stock selection approach. This means that the
investment manager concentrates on individual company fundamentals, rather than
on a particular industry. In selecting investments, the investment manager seeks
to identify value companies that it believes display one or more of the
following:


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

Value Companies:

Those companies believed by the
investment manager to be
undervalued, either historically,
by the market, or by their peers.

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


     o    A low price-to-earnings and/or low price-to-book ratio

     o    Positive change in senior management

     o    Positive corporate restructuring

     o    Temporary setback in price due to factors that no longer exist

The Portfolio generally holds a small number of securities because the
investment manager believes doing so allows it to adhere to its disciplined
value investment approach. The investment manager maintains close contact with
the management of each company in which the Portfolio invests and continually
monitors portfolio holdings, remaining sensitive to overvaluation and
deteriorating fundamentals.

The Portfolio generally sells a stock if the investment manager believes it has
become fully valued, its fundamentals have deteriorated, or ongoing evaluation
reveals that there are more attractive investment opportunities available.

The Portfolio invests primarily in equity-related securities of domestic
issuers. These securities may include common stock, preferred stock and stock
convertible into or exchangeable for such securities. The Portfolio expects that
no more than 15% of its assets will be invested in cash or fixed-income
securities, except as a temporary defensive measure. The Portfolio may also
invest in American Depository Receipts (ADRs). ADRs are publicly traded
instruments generally issued by domestic banks or trust companies that represent
a security of a foreign issuer. ADRs are quoted and settled in US dollars. The
Portfolio uses the same criteria in evaluating these securities as it does for
common stocks.


                                      P-1

<PAGE>


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


The Portfolio may change its principal strategies, except for stated fundamental
policies, if the Fund's Board of Directors believes doing so is consistent with
the Portfolio's objective. The Portfolio's objective and any fundamental
policies may be changed only with shareholder approval. If a change of objective
or fundamental policies is proposed, Contract owners will be asked to give
voting instructions to the participating insurance companies.

The Portfolio 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 Portfolio from achieving its objective.


The Fund's Board of Directors may change the parameters by which large market
capitalization is defined if it concludes such a change is appropriate.

There is no guarantee that the Portfolio will achieve its objective.


PRINCIPAL RISKS

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

The Portfolio holds a small number of securities. Consequently, if one or more
of the securities held in its portfolio declines in value or underperforms
relative to the market, it may have a greater impact on the Portfolio's
performance than if the Portfolio held a larger number of securities. The
Portfolio may experience more volatility, especially over the short term, than a
fund with a greater number of holdings.

The Portfolio may not invest more than 25% of its total assets in securities of
companies in any one industry. However, the Portfolio may invest more heavily in
certain industries believed to offer good investment opportunities. If an
industry in which the Portfolio is invested falls out of favor, the Portfolio's
performance may be negatively affected. This effect may be heightened because
the Portfolio holds a smaller number of securities.

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

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


Due to differences of tax treatment and other considerations, there is a
possibility that the interests of various Contract owners who own shares of the
Portfolio may conflict. The Board of Directors monitors events in order to
identify any disadvantages or material irreconcilable conflicts and to determine
what action, if any, should be taken in response.


An investment in the Portfolio 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 information below provides some indication of the risks of investing in the
Portfolio by showing how the performance of Class 1 shares over the periods
compares to three widely-used measures of performance. How the Portfolio has
performed in the past, however, is not necessarily an indication of how it will
perform in the future.


Class 1 annual total return presented in the bar chart and average annual total
returns presented in the table do not reflect the effect of any administration
fees or sales charges imposed by the Contracts on their owners. If these
expenses were included, the returns would be lower. Both the bar chart and table
assume that all dividends and capital gain distributions were reinvested.

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

The Standard & Poor's 500 Composite Stock Price Index (S&P 500 Index), the
Russell 1000 Value Index and the Russell 1000 Index are unmanaged benchmarks
that assume the reinvestment of dividends and exclude the effect of fees and
sales charges.

In the future, the Portfolio will no longer be compared to the Russell 1000
Index, as it measures the performance of 1,000 widely held large capitalization
stocks. Instead, the Portfolio will be compared to the Russell 1000 Value Index,
which the investment manager believes is a more appropriate benchmark because it
measures the performance of large-cap value stocks, and the Portfolio invests
primarily in these types of stocks. Therefore, the Portfolio will continue to be
compared to the Russell 1000 Value Index and the S&P 500 Index.

Shareholder Information

PRICING OF FUND SHARES

When you buy or sell shares, you do so at the Portfolio's net asset value (NAV)
next calculated after your request is received by participating insurance
companies. If your purchase or sell request is received by participating
insurance companies by the close of regular trading on the New York Stock
Exchange (NYSE) (normally 4:00 p.m. Eastern time), it will be executed at the
Portfolio's NAV calculated as of the close of regular trading on the NYSE on
that day.

If your purchase or sell request is received by participating insurance
companies after the close of regular trading on the NYSE, your request will be
executed at the Portfolio's NAV calculated as of the close of regular trading on
the next NYSE trading day.

The NAV of the Portfolio is computed each day, Monday through Friday, on days
that the NYSE is open for trading. Securities owned by the Portfolio are valued
at current market prices. If reliable market prices are unavailable, securities
are valued in accordance with procedures approved by the Fund's Board of
Directors.


HOW TO PURCHASE AND SELL SHARES

The Portfolio is offering its shares only to Accounts of participating insurance
companies to fund benefits of the Contracts. The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.

An Account may sell all or any portion of the Portfolio shares that it holds at
any time at the next computed NAV per share, as described above. Portfolio
shares that are sold are entitled to any dividends that have been declared as
payable to record owners up to and including the day the sale is effected. There
is no charge. Payment of the sale price will normally be made within seven days
after receipt of such sale. In addition, the right to sell your shares may be
suspended and the date of payment of the sale price may be postponed for any
period during which the NYSE is closed (other than customary weekend and holiday
closings) or during which the Securities and Exchange Commission (SEC)
determines that trading thereon is restricted, or for any period during which an
emergency (as determined by the SEC) exists as a result of which the sale of
Portfolio shares is not reasonably practicable or as a result of which it is not
reasonably practicable for the Portfolio to fairly determine the value of its
net assets, or for such other periods as the SEC may by order permit for the
protection of shareholders.

Financial Highlights

The table below describes the Portfolio's performance for the period of the
Portfolio's operations. It is intended to help you understand the financial
performance of the Portfolio's Class 1 shares. Certain information reflects
financial results for a single share of the Portfolio that was held throughout
the periods shown. "Total return" shows the rate that you would have earned (or
lost) on an investment in the Portfolio. Total returns do not reflect the effect
of any administration fees or sales charges imposed by the Contracts on their
owners. Ernst & Young LLP, independent auditors, have audited this information.
Their report, along with the Portfolio's financial statements, is included in
the Fund's annual report, which is available upon request.

The Fund and the Portfolio

OVERVIEW OF THE FUND

Seligman Portfolios, Inc. (the Fund) consists of 15 separate portfolios. This
Prospectus contains information about Seligman Large-Cap Value Portfolio (the
Portfolio).


The Portfolio is offering its shares only to separate accounts (Accounts) of
participating insurance companies to fund benefits of variable annuity and
variable life insurance contracts (Contracts). The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.


The Portfolio offers two classes of shares: Class 1 shares and Class 2 shares.
This Prospectus offers only Class 2 shares and is for use with Accounts that
make Class 2 shares available to Contract owners.

INVESTMENT OBJECTIVE

The Portfolio's objective is long-term capital appreciation.

PRINCIPAL INVESTMENT STRATEGIES

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

The Portfolio generally invests at least 65% of its total assets in the common
stocks of "value" companies with large market capitalization ($2 billion or
more) at the time of purchase by the Portfolio. The Portfolio uses a bottom-up
stock selection approach. This means that the investment manager concentrates on
individual company fundamentals, rather than on a particular industry. In
selecting investments, the investment manager seeks to identify value companies
that it believes display one or more of the following:

          o    A low price-to-earnings and/or low price-to-book ratio

          o    Positive change in senior management

          o    Positive corporate restructuring

          o    Temporary setback in price due to factors that no longer exist

- -------------------------------------
Value Companies:

Those companies believed by the
investment manager to be undervalued,
either historically, by the market,
or by their peers.
- -------------------------------------

The Portfolio generally holds a small number of securities because the
investment manager believes doing so allows it to adhere to its disciplined
value investment approach. The investment manager maintains close contact with
the management of each company in which the Portfolio invests and continually
monitors portfolio holdings, remaining sensitive to overvaluation and
deteriorating fundamentals.

The Portfolio generally sells a stock if the investment manager believes it has
become fully valued, its fundamentals have deteriorated, or ongoing evaluation
reveals that there are more attractive investment opportunities available.

The Portfolio invests primarily in equity-related securities of domestic
issuers. These securities may include common stock, preferred stock and stock
convertible into or exchangeable for such securities. The Portfolio expects that
no more than 15% of its assets will be invested in cash or fixed-income
securities, except as a temporary defensive measure. The Portfolio may also
invest in American Depository Receipts (ADRs). ADRs are publicly traded
instruments generally issued by domestic banks or trust companies that represent
a security of a foreign issuer. ADRs are quoted and settled in US dollars. The
Portfolio uses the same criteria in evaluating these securities as it does for
common stocks.


                                      P-1

<PAGE>


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


The Portfolio may change its principal strategies, except for stated fundamental
policies, if the Fund's Board of Directors believes doing so is consistent with
the Portfolio's objective. The Portfolio's objective and any fundamental
policies may be changed only with shareholder approval. If a change of objective
or fundamental policies is proposed, Contract owners will be asked to give
voting instructions to the participating insurance companies.

The Portfolio 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 Portfolio from achieving its objective.


The Fund's Board of Directors may change the parameters by which large market
capitalization is defined if it concludes such a change is appropriate.

There is no guarantee that the Portfolio will achieve its objective.

PRINCIPAL RISKS

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

The Portfolio holds a small number of securities. Consequently, if one or more
of the securities held in its portfolio declines in value or underperforms
relative to the market, it may have a greater impact on the Portfolio's
performance than if the Portfolio held a larger number of securities. The
Portfolio may experience more volatility, especially over the short term, than a
fund with a greater number of holdings.

The Portfolio may not invest more than 25% of its total assets in securities of
companies in any one industry. However, the Portfolio may invest more heavily in
certain industries believed to offer good investment opportunities. If an
industry in which the Portfolio is invested falls out of favor, the Portfolio's
performance may be negatively affected. This effect may be heightened because
the Portfolio holds a smaller number of securities.

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

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


Due to differences of tax treatment and other considerations, there is a
possibility that the interests of various Contract owners who own shares of the
Portfolio may conflict. The Board of Directors monitors events in order to
identify any disadvantages or material irreconcilable conflicts and to determine
what action, if any, should be taken in response.


An investment in the Portfolio 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

Class 2 shares are newly offered and have no performance history. The
information below provides some indication of the risks of investing in the
Portfolio by showing how the performance of Class 1 shares over the periods
compares to three widely-used measures of performance. How the Portfolio has
performed in the past, however, is not necessarily an indication of how it will
perform in the future.


Total returns will vary between Class 1 shares and Class 2 shares due to
different expenses of the two Classes. Class 1 annual total return presented in
the bar chart and average annual total returns presented in the table do not
reflect the effect of the shareholder servicing and distribution (12b-1) fees
associated with Class 2 shares or the effect of any administration fees or sales
charges imposed by the Contracts on their owners. If these expenses were
included, the returns would be lower. Both the bar chart and table assume that
all dividends and capital gain distributions were reinvested.

The Standard & Poor's 500 Composite Stock Price Index (S&P 500 Index), the
Russell 1000 Value Index and the Russell 1000 Index are unmanged benchmarks that
assume the reinvestment of dividends and exclude the effect of fees and sales
charges. In the future, the Portfolio will no longer be compared to the Russell
1000 Index, as it measures the performance of 1,000 widely held large
capitalization stocks. Instead, the Portfolio will be compared to the Russell
1000 Value Index, which the investment manager believes is a more appropriate
benchmark because it measures the performance of large-cap value stocks, and the
Portfolio invests primarily in these types of stocks. Therefore, the Portfolio
will continue to be compared to the Russell 1000 Value Index and the S&P 500
Index.

Shareholder Information

PRICING OF FUND SHARES

When you buy or sell shares, you do so at the Portfolio's net asset value (NAV)
next calculated after your request is received by participating insurance
companies. If your purchase or sell request is received by participating
insurance companies by the close of regular trading on the New York Stock
Exchange (NYSE) (normally 4:00 p.m. Eastern time), it will be executed at the
Portfolio's NAV calculated as of the close of regular trading on the NYSE on
that day.

If your purchase or sell request is received by participating insurance
companies after the close of regular trading on the NYSE, your request will be
executed at the Portfolio's NAV calculated as of the close of regular trading on
the next NYSE trading day.

The NAV of the Portfolio is computed each day, Monday through Friday, on days
that the NYSE is open for trading. Securities owned by the Portfolio are valued
at current market prices. If reliable market prices are unavailable, securities
are valued in accordance with procedures approved by the Fund's Board of
Directors.

HOW TO PURCHASE AND SELL SHARES

The Portfolio is offering its shares only to Accounts of participating insurance
companies to fund benefits of the Contracts. The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.

An Account may sell all or any portion of the Portfolio shares that it holds at
any time at the next computed NAV per share, as described above. Portfolio
shares that are sold are entitled to any dividends that have been declared as
payable to record owners up to and including the day the sale is effected. There
is no charge. Payment of the sale price will normally be made within seven days
after receipt of such sale. In addition, the right to sell your shares may be
suspended and the date of payment of the sale price may be postponed for any
period during which the NYSE is closed (other than customary weekend and holiday
closings) or during which the Securities and Exchange Commission (SEC)
determines that trading thereon is restricted, or for any period during which an
emergency (as determined by the SEC) exists as a result of which the sale of
Portfolio shares is not reasonably practicable or as a result of which it is not
reasonably practicable for the Portfolio to fairly determine the value of its
net assets, or for such other periods as the SEC may by order permit for the
protection of shareholders.


SHAREHOLDER SERVICING AND DISTRIBUTION ARRANGEMENTS

Under a Rule 12b-1 plan adopted by the Fund with respect to the Portfolio, Class
2 shares pay an annual shareholder servicing and distribution (12b-1) fee of up
to 0.25% of average net assets. The Portfolio pays this fee to Seligman
Advisors, Inc., the principal underwriter of the Portfolio's shares. Seligman
Advisors uses this fee to make payments to participating insurance companies or
their affiliates for services that the participating insurance companies provide
to Contract owners of Class 2 shares, and for distribution related expenses.
Because these 12b-1 fees are paid out of the Portfolio's assets on an ongoing
basis, over time they will increase the cost of a Contract owner's investment
and may cost you more than other types of sales charges.

DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS

Dividends and capital gain distributions from the Portfolio will be declared and
paid annually and will be reinvested in additional shares, at NAV, of the
Portfolio. Dividends on Class 2 shares generally will be lower than the
dividends on Class 1 shares as a result of 12b-1 fees. Capital gain
distributions will be paid in the same amount for each Class.

TAXES

Further information regarding the tax consequences of an investment in the
Portfolio is contained in the separate prospectuses and disclosure documents
issued by the participating insurance companies and accompanying this
Prospectus.

Financial Highlights


The table below describes the Portfolio's performance for the period of the
Portfolio's operations. It is intended to help you understand the financial
performance of the Portfolio's Class 1 shares. Class 2 shares are a newly
offered Class, effective May 1, 2000, so financial highlights are not available.
Certain information reflects financial results for a single share of the
Portfolio that was held throughout the periods shown. "Total return" shows the
rate that you would have earned (or lost) on an investment in the Portfolio.
Total returns do not reflect the effect of the shareholder servicing and
distribution (12b-1) fees associated with Class 2 shares or any administration
fees or sales charges imposed by the Contracts on their owners. Ernst & Young
LLP, independent auditors, have audited this information. Their report, along
with the Portfolio's financial statements, is included in the Fund's annual
report, which is available upon request.

The Fund and the Portfolio

OVERVIEW OF THE FUND

Seligman Portfolios, Inc. (the Fund) consists of 15 separate portfolios. This
Prospectus contains information about Seligman Small-Cap Value Portfolio (the
Portfolio).


The Portfolio is offering its shares only to separate accounts (Accounts) of
participating insurance companies to fund benefits of variable annuity and
variable life insurance contracts (Contracts). The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.


The Portfolio offers two classes of shares: Class 1 shares and Class 2 shares.
This Prospectus offers only Class 1 shares and is for use with Accounts that
make Class 1 shares available to Contract owners.

INVESTMENT OBJECTIVE

The Portfolio's objective is long-term capital appreciation.

PRINCIPAL INVESTMENT STRATEGIES

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

The Portfolio generally invests at least 65% of its total assets in the common
stocks of "value" companies with small market capitalization (up to $1 billion)
at the time of purchase by the Portfolio.

The Portfolio uses a bottom-up stock selection approach. This means that the
investment manager concentrates on individual company fundamentals, rather than
on a particular industry. In selecting investments, the investment manager seeks
to identify value companies that it believes display one or more of the
following:

- ------------------------------------
Value Companies:

Those companies believed by the
investment manager to be undervalued
either historically, by the market,
or by their peers.
- ------------------------------------

o    A low price-to-earnings and/or low price-to-book ratio

o    Positive change in senior management

o    Positive corporate restructuring

o    Temporary setback in price due to factors that no longer exist

The Portfolio generally holds a small number of securities because the
investment manager believes doing so allows it to adhere to its disciplined
value investment approach. The investment manager maintains close contact with
the management of each company in which the Portfolio invests and continually
monitors portfolio holdings, remaining sensitive to overvaluation and
deteriorating fundamentals.

The Portfolio generally sells a stock if the investment manager believes it has
become fully valued, its fundamentals have deteriorated, or ongoing evaluation
reveals that there are more attractive investment opportunities available.

The Portfolio invests primarily in equity-related securities of domestic
issuers. These securities may include common stock, preferred stock and stock
convertible into or exchangeable for such securities. The Portfolio expects that
no more than 15% of its assets will be invested in cash or fixed-income
securities, except as a temporary defensive measure. The Portfolio may also
invest in American Depository Receipts (ADRs). ADRs are publicly traded
instruments generally issued by domestic banks or trust companies that represent
a security of a foreign issuer. ADRs are quoted and settled in US dollars. The
Portfolio uses the same criteria in evaluating these securities as it does for
common stocks.


                                      P-1
<PAGE>


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


The Portfolio may change its principal strategies, except for stated fundamental
policies, if the Fund's Board of Directors believes doing so is consistent with
the Portfolio's objective. The Portfolio's objective and any fundamental
policies may be changed only with shareholder approval. If a change of objective
or fundamental policies is proposed, Contract owners will be asked to give
voting instructions to the participating insurance companies.

The Portfolio 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 Portfolio from achieving its objective.


The Fund's Board of Directors may change the parameters by which small market
capitalization is defined if it concludes such a change is appropriate.

There is no guarantee that the Portfolio will achieve its objective.

PRINCIPAL RISKS

Stock prices fluctuate. Therefore, as with any portfolio that invests in stocks,
the Portfolio's net asset value will fluctuate, especially in the short term.
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.


Small company stocks, as a whole, may experience larger price fluctuations than
large company stocks or other types of investments. Small companies tend to have
shorter operating histories, and may have less experienced management. During
periods of investor uncertainty, investor sentiment may favor large, well-known
companies over small, lesser-known companies.


The Portfolio holds a small number of securities. Consequently, if one or more
of the securities held in its portfolio declines in value or underperforms
relative to the market, it may have a greater impact on the Portfolio's
performance than if the Portfolio held a larger number of securities. The
Portfolio may experience more volatility, especially over the short term, than a
fund with a greater number of holdings.

The Portfolio may not invest more than 25% of its total assets in securities of
companies in any one industry. However, the Portfolio may invest more heavily in
certain industries that the investment manager believes offer good investment
opportunities. If an industry in which the Portfolio is invested falls out of
favor, the Portfolio's performance may be negatively affected. This effect may
be heightened because the Portfolio holds a smaller number of securities.

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

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


Due to differences of tax treatment and other considerations, there is a
possibility that the interests of various Contract owners who own shares of the
Portfolio may conflict. The Board of Directors monitors events in order to
identify any disadvantages or material irreconcilable conflicts and to determine
what action, if any, should be taken in response.


An investment in the Portfolio 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 information below provides some indication of the risks of investing in the
Portfolio by showing how the performance of Class 1 shares over the periods
compares to two widely-used measures of performance. How the Portfolio has
performed in the past, however, is not necessarily an indication of how it will
perform in the future.

Class 1 annual total return presented in the bar chart and average annual total
returns presented in the table do not reflect the effect of any administration
fees or sales charges imposed by the Contracts on their owners. If these
expenses were included, the returns would be lower. Both the bar chart and table
assume that all dividends and capital gain distributions were reinvested.

Shareholder Information

PRICING OF FUND SHARES

When you buy or sell shares, you do so at the Portfolio's net asset value (NAV)
next calculated after your request is received by participating insurance
companies. If your purchase or sell request is received by participating
insurance companies by the close of regular trading on the New York Stock
Exchange (NYSE) (normally 4:00 p.m. Eastern time), it will be executed at the
Portfolio's NAV calculated as of the close of regular trading on the NYSE on

If your purchase or sell request is received by participating insurance
companies after the close of regular trading on the NYSE, your request will be
executed at the Portfolio's NAV calculated as of the close of regular trading on
the next NYSE trading day.

The NAV of the Portfolio is computed each day, Monday through Friday, on days
that the NYSE is open for trading. Securities owned by the Portfolio are valued
at current market prices. If reliable market prices are unavailable, securities
are valued in accordance with procedures approved by the Fund's Board of
Directors.

HOW TO PURCHASE AND SELL SHARES

The Portfolio is offering its shares only to Accounts of participating insurance
companies to fund benefits of the Contracts. The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.

An Account may sell all or any portion of the Portfolio shares that it holds at
any time at the next computed NAV per share, as described above. Portfolio
shares that are sold are entitled to any dividends that have been declared as
payable to record owners up to and including the day the sale is effected. There
is no charge. Payment of the sale price will normally be made within seven days
after receipt of such sale. In addition, the right to sell your shares may be
suspended and the date of payment of the sale price may be postponed for any
period during which the NYSE is closed (other than customary weekend and holiday
closings) or during which the Securities and Exchange Commission (SEC)
determines that trading thereon is restricted, or for any period during which an
emergency (as determined by the SEC) exists as a result of which the sale of
Portfolio shares is not reasonably practicable or as a result of which it is not
reasonably practicable for the Portfolio to fairly determine the value of its
net assets, or for such other periods as the SEC may by order permit for the
protection of shareholders.

The Fund and the Portfolio

OVERVIEW OF THE FUND


Seligman Portfolios, Inc. (the Fund) consists of 15 separate portfolios. This
Prospectus contains information about Seligman Small-Cap Value Portfolio (the
Portfolio).

The Portfolio is offering its shares only to separate accounts (Accounts) of
participating insurance companies to fund benefits of variable annuity and
variable life insurance contracts (Contracts). The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.


The Portfolio offers two classes of shares: Class 1 shares and Class 2 shares.
This Prospectus offers only Class 2 shares and is for use with Accounts that
make Class 2 shares available to Contract owners.

INVESTMENT OBJECTIVE

The Portfolio's objective is long-term capital appreciation.

PRINCIPAL INVESTMENT STRATEGIES

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

The Portfolio generally invests at least 65% of its total assets in the common
stocks of "value" companies with small market capitalization (up to $1 billion)
at the time of purchase by the Portfolio. The Portfolio uses a bottom-up stock
selection approach. This means that the investment manager concentrates on
individual company fundamentals, rather than on a particular industry. In
selecting investments, the investment manager seeks to identify value companies
that it believes display one or more of the following:

     o    A low price-to-earnings and/or low price-to-book ratio

     o    Positive change in senior management

     o    Positive corporate restructuring

     o    Temporary setback in price due to factors that no longer exist

- ---------------------------------------
Value Companies:

Those companies believed by the
investment manager to be undervalued,
either historically, by the market,
or by their peers.
- ---------------------------------------

The Portfolio generally holds a small number of securities because the
investment manager believes doing so allows it to adhere to its disciplined
value investment approach. The investment manager maintains close contact with
the management of each company in which the Portfolio invests and continually
monitors portfolio holdings, remaining sensitive to overvaluation and
deteriorating fundamentals.

The Portfolio generally sells a stock if the investment manager believes it has
become fully valued, its fundamentals have deteriorated, or ongoing evaluation
reveals that there are more attractive investment opportunities available.

The Portfolio invests primarily in equity-related securities of domestic
issuers. These securities may include common stock, preferred stock and stock
convertible into or exchangeable for such securities. The Portfolio expects that
no more than 15% of its assets will be invested in cash or fixed-income
securities, except as a temporary defensive measure. The Portfolio may also
invest in American Depository Receipts (ADRs). ADRs are publicly traded
instruments generally issued by domestic banks or trust companies that represent
a security of a foreign issuer. ADRs are quoted and settled in US dollars. The
Portfolio uses the same criteria in evaluating these securities as it does for
common stocks.


                                      P-1
<PAGE>

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


The Portfolio may change its principal strategies, except for stated fundamental
policies, if the Fund's Board of Directors believes doing so is consistent with
the Portfolio's objective. The Portfolio's objective and any fundamental
policies may be changed only with shareholder approval. If a change of objective
or fundamental policies is proposed, Contract owners will be asked to give
voting instructions to the participating insurance companies.

The Portfolio 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 Portfolio from achieving its objective.


The Fund's Board of Directors may change the parameters by which small market
capitalization is defined if it concludes such a change is appropriate.

There is no guarantee that the Portfolio will achieve its objective.

PRINCIPAL RISKS

Stock prices fluctuate. Therefore, as with any portfolio that invests in stocks,
the Portfolio's net asset value will fluctuate, especially in the short term.
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.


Small company stocks, as a whole, may experience larger price fluctuations than
large company stocks or other types of investments. Small companies tend to have
shorter operating histories, and may have less experienced management. During
periods of investor uncertainty, investor sentiment may favor large, well-known
companies over small, lesser-known companies.


The Portfolio holds a small number of securities. Consequently, if one or more
of the securities held in its portfolio declines in value or underperforms
relative to the market, it may have a greater impact on the Portfolio's
performance than if the Portfolio held a larger number of securities. The
Portfolio may experience more volatility, especially over the short term, than a
fund with a greater number of holdings.

The Portfolio may not invest more than 25% of its total assets in securities of
companies in any one industry. However, the Portfolio may invest more heavily in
certain industries that the investment manager believes offer good investment
opportunities. If an industry in which the Portfolio is invested falls out of
favor, the Portfolio's performance may be negatively affected. This effect may
be heightened because the Portfolio holds a smaller number of securities.

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

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


Due to differences of tax treatment and other considerations, there is a
possibility that the interests of various Contract owners who own shares of the
Portfolio may conflict. The Board of Directors monitors events in order to
identify any disadvantages or material irreconcilable conflicts and to determine
what action, if any, should be taken in response.


An investment in the Portfolio 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


Class 2 shares are newly offered and have no performance history. The
information below provides some indication of the risks of investing in the
Portfolio by showing how the performance of Class 1 shares over the periods
compares to two widely-used measures of performance. How the Portfolio has
performed in the past, however, is not necessarily an indication of how it will
perform in the future.

Total returns will vary between Class 1 shares and Class 2 shares due to
different expenses of the two Classes. Class 1 annual total return presented in
the bar chart and average annual total returns presented in the table do not
reflect the effect of the shareholder servicing and distribution (12b-1) fees
associated with Class 2 shares or the effect of any administration fees or sales
charges imposed by the Contracts on their owners. If these expenses were
included, the returns would be lower. Both the bar chart and table assume that
all dividends and capital gain distributions were reinvested.

Portfolio's NAV calculated as of the close of regular trading on the NYSE on
that day.

If your purchase or sell request is received by participating insurance
companies after the close of regular trading on the NYSE, your request will be
executed at the Portfolio's NAV calculated as of the close of regular trading on
the next NYSE trading day.

The NAV of the Portfolio is computed each day, Monday through Friday, on days
that the NYSE is open for trading. Securities owned by the Portfolio are valued
at current market prices. If reliable market prices are unavailable, securities
are valued in accordance with procedures approved by the Fund's Board of
Directors.

HOW TO PURCHASE AND SELL SHARES

The Portfolio is offering its shares only to Accounts of participating insurance
companies to fund benefits of the Contracts. The Accounts may invest in shares
of the Portfolio in accordance with allocation instructions received from the
owners of the Contracts. Such allocations rights and information on how to
purchase or surrender a Contract, as well as sales charges and other expenses
imposed by the Contracts on their owners, are further described in the separate
prospectuses and disclosure documents issued by the participating insurance
companies and accompanying this Prospectus. The Fund reserves the right to
reject any order for the purchase of shares of the Portfolio.

An Account may sell all or any portion of the Portfolio shares that it holds at
any time at the next computed NAV per share, as described above. Portfolio
shares that are sold are entitled to any dividends that have been declared as
payable to record owners up to and including the day the sale is effected. There
is no charge. Payment of the sale price will normally be made within seven days
after receipt of such sale. In addition, the right to sell your shares may be
suspended and the date of payment of the sale price may be postponed for any
period during which the NYSE is closed (other than customary weekend and holiday
closings) or during which the Securities and Exchange Commission (SEC)
determines that trading thereon is restricted, or for any period during which an
emergency (as determined by the SEC) exists as a result of which the sale of
Portfolio shares is not reasonably practicable or as a result of which it is not
reasonably practicable for the Portfolio to fairly determine the value of its
net assets, or for such other periods as the SEC may by order permit for the
protection of shareholders.


SHAREHOLDER SERVICING AND DISTRIBUTION ARRANGEMENTS

Under a Rule 12b-1 plan adopted by the Fund with respect to the Portfolio, Class
2 shares pay an annual shareholder servicing and distribution (12b-1) fee of up
to 0.25% of average net assets. The Portfolio pays this fee to Seligman
Advisors, Inc., the principal underwriter of the Portfolio's shares. Seligman
Advisors uses this fee to make payments to participating insurance companies or
their affiliates for services that the participating insurance companies provide
to Contract owners of Class 2 shares, and for distribution related expenses.
Because these 12b-1 fees are paid out of the Portfolio's assets on an ongoing
basis, over time they will increase the cost of a Contract owner's investment
and may cost you more than other types of sales charges.

DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS

Dividends and capital gain distributions from the Portfolio will be declared and
paid annually and will be reinvested in additional shares, at NAV, of the
Portfolio. Dividends on Class 2 shares generally will be lower than the
dividends on Class 1 shares as a result of 12b-1 fees. Capital gain
distributions will be paid in the same amount for each Class.

TAXES

Further information regarding the tax consequences of an investment in the
Portfolio is contained in the separate prospectuses and disclosure documents
issued by the participating insurance companies and accompanying this
Prospectus.

Financial Highlights


The table below describes the Portfolio's performance for the period of the
Portfolio's operations. It is intended to help you understand the financial
performance of the Portfolio's Class 1 shares. Class 2 shares are a newly
offered Class, effective May 1, 2000, so financial highlights are not available.
Certain information reflects financial results for a single share of the
Portfolio that was held throughout the periods shown. "Total return" shows the
rate that you would have earned (or lost) on an investment in the Portfolio.
Total returns do not reflect the effect of the shareholder servicing and
distribution (12b-1) fees associated with Class 2 shares or any administration
fees or sales charges imposed by the Contracts on their owners. Ernst & Young
LLP, independent auditors, have audited this information. Their report, along
with the Portfolio's financial statements, is included in the Fund's annual
report, which is available upon request.

The Fund's Portfolios are offering their shares only to separate accounts
(Accounts) of participating insurance companies to fund benefits of variable
annuity and variable life insurance contracts (Contracts). The Accounts may
invest in shares of the Portfolios in accordance with allocation instructions
received from the owners of the Contracts. Such allocations rights and
information on how to purchase or surrender a Contract, as well as sales charges
and other expenses imposed by the Contracts on their owners, are further
described in the separate prospectuses and disclosure documents issued by the
participating insurance companies and accompanying each Portfolio's Prospectus.
The Fund reserves the right to reject any order for the purchase of shares of
the Fund's Portfolios.


Investment Strategies and Risks

The Prospectuses discuss the investment objectives of each of the Fund's
Portfolios and the policies each Portfolio employs to achieve its objectives.
The following information regarding the Fund's Portfolios' investment policies
supplements the information contained in the Prospectuses.

Convertible Bonds

Each Portfolio, other than Seligman Cash Management Portfolio, may purchase
convertible bonds. Convertible bonds are convertible at a stated exchange rate
or price into common stock. Before conversion, convertible securities are
similar to non-convertible debt securities in that they provide a steady stream
of income with generally higher yields than an issuer's equity securities. The
market value of all debt securities, including convertible securities, tends to
decline as interest rates increase and to increase as interest rates decline. In
general, convertible securities may provide lower interest or dividend yields
than non-convertible debt securities

                                       2
<PAGE>

of similar quality, but they may also allow investors to benefit from increases
in the market price of the underlying common stock. When the market price of the
underlying common stock increases, the price of the convertible security tends
to reflect the increase. When the market price of the underlying common stock
declines, the convertible security tends to trade on the basis of yield, and may
not depreciate to the same extent as the underlying common stock. In an issuer's
capital structure, convertible securities are senior to common stocks. They are
therefore of higher quality and involve less risk than the issuer's common
stock, but the extent to which risk is reduced depends largely on the extent to
which the convertible security sells above its value as a fixed-income security.
In selecting convertible securities for a Portfolio, the investment manager
evaluates such factors as economic and business conditions involving the issuer,
future earnings growth potential of the issuer, potential for price appreciation
of the underlying equity, the value of individual securities relative to other
investment alternatives, trends in the determinants of corporate profits, and
capability of management. In evaluating a convertible security, the investment
manager gives emphasis to the attractiveness of the underlying common stock and
the capital appreciation opportunities that the convertible security presents.
Convertible securities can be callable or redeemable at the issuer's discretion,
in which case the investment manager would be forced to seek alternative
investments. The Portfolios may invest in debt securities convertible into
equity securities rated as low as CC by Standard & Poor's Ratings Services (S&P)
or Ca by Moody's Investors Service (Moody's). Debt securities rated below
investment-grade (frequently referred to as "junk bonds") often have speculative
characteristics and will be subject to greater market fluctuations and risk of
loss of income and principal than higher-rated securities. A description of
credit ratings and risks associated with lower-rated debt securities is set
forth in Appendix A to this SAI. The investment manager does not rely on the
ratings of these securities in making investment decisions but performs its own
analysis, based on the factors described above, in light of the Portfolio's
investment objectives.


Derivatives

Each of the Portfolios, other than Seligman Cash Management Portfolio and
Seligman Bond Portfolio, may invest in financial instruments commonly known as
"derivatives" only for hedging or investment purposes. A Portfolio will not
invest in derivatives for speculative purposes, i.e., where the derivative
investment exposes the Portfolio 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 Portfolio will
not invest in a specific type of derivative without prior approval from its
Board of Directors, after consideration of, among other things, how the
derivative instrument serves the Portfolio's investment objective, and the risk
associated with the investment. The only types of derivatives in which the
Portfolios are currently permitted to invest, as described more fully below, are
forward currency exchange contracts, put options, and rights and warrants.

Forward Foreign Currency Exchange Contracts

Each of Seligman Global Growth Portfolio, Seligman Global Smaller Companies
Portfolio, Seligman Global Technology Portfolio and Seligman International
Growth Portfolio (collectively, the Global Portfolios) will generally enter into
forward foreign currency exchange contracts to fix the US dollar value of a
security it has agreed to buy or sell for the period between the date the trade
was entered into and the date the security is delivered and paid for, or, to
hedge the US dollar value of securities it owns. 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 Portfolio may enter into a forward contract to sell or buy the amount of a
foreign currency it believes may experience a substantial movement against the
US dollar. In this case the contract would approximate the value of some or all
of the Portfolio's securities denominated in such foreign currency. Under normal
circumstances, the investment manager will limit forward currency contracts to
not greater than 75% of a Portfolio's position in any one country as of the date
the contract is entered into. This limitation will be measured at the point the
hedging transaction is entered into by the Portfolio. Under extraordinary
circumstances, the Fund's investment manager (or subadviser, in the case of
Seligman Global Smaller Companies Portfolio) may enter into forward currency
contracts in excess of 75% of a Portfolio's position in any one country as of
the date the contract is entered into. The precise matching of the forward
contract amounts and the value of securities involved will not generally be
possible since the

                                       3
<PAGE>

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 Portfolio may commit a substantial portion or the entire value
of its assets to the consummation of these contracts. The Fund's investment
manager (or subadviser, in the case of Seligman Global Smaller Companies
Portfolio) will consider the effect a substantial commitment of its assets to
forward contracts would have on the investment program of a Portfolio and its
ability to purchase additional securities.


Except as set forth above and immediately below, each Portfolio will not enter
into forward contracts or maintain a net exposure to such contracts where the
consummation of the contracts would oblige the Portfolio to deliver an amount of
foreign currency in excess of the value of the Portfolio's securities or other
assets denominated in that currency. A Portfolio, in order to avoid excess
transactions and transaction costs, may nonetheless maintain a net exposure to
forward contracts in excess of the value of the Portfolio's securities or other
assets denominated in that currency provided the excess amount is "covered" by
cash and/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 Fund's investment manager (and
subadviser, in the case of Seligman Global Smaller Companies Portfolio) believe
that it is important to have the flexibility to enter into such forward
contracts when they determine that the best interests of the Portfolio will be
served.

At the maturity of a forward contract, a Portfolio may either sell the 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 Portfolio 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 the
Portfolio 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 Portfolio is obligated to deliver. However, a Portfolio 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 Portfolio retains the portfolio security and engages in offsetting
transactions, the Portfolio will incur a gain or a loss (as described below) to
the extent that there has been movement in forward contract prices. If the
Portfolio engages in an offsetting transaction, it may subsequently enter into a
new forward contract to sell the foreign currency. Should forward prices decline
during the period between the Portfolio's entering into a forward contract for
the sale of a foreign currency and the date it enters into an offsetting
contract for the purchase of the foreign currency, the Portfolio will realize a
gain to the extent the price of the currency it has agreed to sell exceeds the
price of the currency it has agreed to purchase. Should forward prices increase,
the Portfolio 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.

Each Portfolio's dealing in forward foreign currency exchange contracts will be
limited to the transactions described above. A Portfolio 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 Fund's investment
manager (or subadviser, in the case of Seligman Global Smaller Companies
Portfolio). It also should be realized that this method of hedging against a
decline in the value of a currency does not eliminate fluctuations in the
underlying prices of the securities. It simply establishes a rate of exchange at
a future date. Additionally, although such contracts tend to minimize the risk
of loss due to a decline in the value of a hedged currency, at the same time,
they tend to limit any potential gain which might result from an increase in the
value of that currency.

Shareholders should be aware of the costs of currency conversion. Although
foreign exchange dealers do not charge a fee for conversion, they do realize a
profit based on the difference (the "spread") between the prices at which they
are buying and selling various currencies. Thus, a dealer may offer to sell a
foreign currency to a

                                       4
<PAGE>


Portfolio at one rate, while offering a lesser rate of exchange should the
Portfolio desire to resell that currency to the dealer.

Put Options

Each Portfolio, other than Seligman Cash Management Portfolio, Seligman Bond
Portfolio, and Seligman High-Yield Bond Portfolio, may purchase put options in
an attempt to provide a hedge against a decrease in the market price of an
underlying security held by a Portfolio. A Portfolio will not purchase options
for speculative purposes. Purchasing a put option gives a Portfolio 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 a Portfolio, 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 Portfolio 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 Portfolio would let the option expire
resulting in a reduced profit on the underlying security equal to the cost of
the put option premium and transaction costs.

When a Portfolio 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 a Portfolio, 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. A Portfolio's maximum financial exposure will
be limited to these costs.

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

Portfolio and Seligman High-Yield Bond Portfolio, 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 each Portfolio's investment restrictions regarding such
securities.

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

Foreign Securities


Each of the Portfolios may invest up to 10% of its total assets in foreign
securities (except the Global Portfolios, which may invest up to 100% of their
total assets in foreign securities), except that this 10% limit does not apply
to foreign securities held through Depositary Receipts which are traded in the
United States or to commercial paper and certificates of deposit issued by
foreign banks. Foreign investments may be affected favorably or unfavorably by
changes in currency rates and exchange control regulations. There may be less
information available about a foreign company than about a US company, and
foreign companies may not be subject to reporting standards and requirements
comparable to those applicable to US companies. Foreign securities may not be as
liquid as US securities. Securities of foreign companies may involve greater
market risk than securities of US companies, and foreign brokerage commissions
and custody fees are generally higher than in the United

                                       5

States. Investments in foreign securities may also be subject to local economic
or political risks, political instability and possible nationalization of
issuers.


By investing in foreign securities, the Portfolios 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. During certain periods, the return on equity investments in some
countries has exceeded the return on similar investments in the United States.
The Fund's investment manager (and subadviser, in the case of Seligman Global
Smaller Companies Portfolio) believe 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. Global diversification reduces the effect
that events in any one country will have on the entire investment portfolio. Of
course, a decline in the value of a Portfolio's investments in one country may
offset potential gains from investments in another country.


Investments in securities of foreign issuers may involve risks that are not
associated with domestic investments, and there can be no assurance that the
Portfolios' 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 settlements may in some instances be subject to delays and
related administrative uncertainties which could result in temporary periods
when assets of a Portfolio are uninvested and no return is earned thereon and
may involve a risk of loss to a Portfolio. Foreign securities markets may have
substantially less 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 nationalization, expropriation or confiscatory taxation (in which
a Portfolio could lose its entire investment in a certain market), limitations
on the removal of monies or other assets of the Portfolios, higher rates of
inflation, 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.


Some of the risks described in the preceding paragraph may be more severe for
investments in emerging or developing countries. By comparison with the United
States and other developed countries, emerging or developing 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
experienced and more recently organized than many domestic companies. Prices of
securities traded in the securities markets of emerging or developing countries
tend to be volatile. Furthermore, foreign investors are subject to many
restrictions in emerging or developing countries. These restrictions may
require, among other things, governmental approval prior to making investments
or repatriating income or capital, 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
developing 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.

Investments in foreign securities will usually be denominated in foreign
currencies, and each Portfolio may temporarily hold funds in foreign currencies.
The value of a Portfolio's investments denominated in foreign currencies may be
affected, favorably or unfavorably, by the relative strength of the US dollar,
changes in foreign

                                       6
<PAGE>


currency and US dollar exchange rates and exchange control regulations. A
Portfolio may incur costs in connection with conversions between various
currencies. A Portfolio'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 the Portfolios. 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 (which in turn are affected by interest rates,
trade flows and numerous other factors, including, in some countries, local
governmental intervention).

Depositary Receipts

Depositary Receipts are instruments generally issued by domestic banks or trust
companies that represent the deposits of a security of a foreign issuer.
American Depositary Receipts (ADRs), which are traded in dollars on US Exchanges
or over-the-counter, are issued by domestic banks and evidence ownership of
securities issued by foreign corporations. European Depositary Receipts (EDRs)
are typically traded in Europe. Global Depositary Receipts (GDRs) are typically
traded in both Europe and the United States. Depositary Receipts may be issued
as sponsored or unsponsored programs. In sponsored programs, the issuer has made
arrangements to have its securities trade in the form of Depositary Receipts. 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
US, and therefore, the import of such information may not be reflected in the
market value of such instruments.

IIliquid Securities


Each Portfolio, other than Seligman Cash Management Portfolio, 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 Portfolio, other than Seligman Cash Management Portfolio, may
purchase restricted securities that can be offered and sold to "qualified
institutional buyers" under Rule 144A of the 1933 Act, and the Fund's Board of
Directors may determine, when appropriate, that specific Rule 144A securities
are liquid and not subject to the 15% limitation on illiquid securities. Should
the Board of Directors make this determination, it will carefully monitor the
security (focusing on such factors, among others, as trading activity and
availability of information) to determine that the Rule 144A security continues
to be liquid. It is not possible to predict with assurance exactly how the
market for Rule 144A securities will further evolve. This investment practice
could have the effect of increasing the level of illiquidity in a Portfolio, if
and to the extent that qualified institutional buyers become for a time
uninterested in purchasing Rule 144A securities.


Money Market Instruments

Each of the Portfolios, other than Seligman Cash Management Portfolio, which
intends to invest primarily in the money market instruments described below, may
invest a portion of their assets in the following money market instruments.

US Government Obligations


US Government Obligations are obligations issued or guaranteed as to both
principal and interest by the US Government or backed by the full faith and
credit of the United States, such as US Treasury Bills, securities issued or
guaranteed by a US Government agency or instrumentality, and securities
supported by the right of the issuer to borrow from the US Treasury.


                                       7
<PAGE>


Bank Obligations

Bank obligations include US dollar-denominated certificates of deposit, banker's
acceptances, fixed time deposits and commercial paper of domestic banks,
including their branches located outside the United States, and of domestic
branches of foreign banks. 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.

Commercial Paper and Short-Term Corporate Debt Securities

Commercial paper and short-term debt securities include short-term unsecured
promissory notes with maturities not exceeding nine months issued in bearer form
by bank holding companies, corporations and finance companies. Investments in
commercial paper issued by bank holding companies will be limited at the time of
investment to the 100 largest US bank holding companies in terms of assets.

Mortgage Related Securities

Mortgage Pass-Through Securities. Each Portfolio may invest in mortgage
pass-through securities. Mortgage pass-through securities include securities
that represent interests in pools of mortgage loans made by lenders such as
savings and loan institutions, mortgage bankers, and commercial banks. Such
securities provide a "pass-through" of monthly payments of interest and
principal made by the borrowers on their residential mortgage loans (net of any
fees paid to the issuer or guarantor of such securities). Although the
residential mortgages underlying a pool may have maturities of up to 30 years, a
pool's effective maturity may be reduced by prepayments of principal on the
underlying mortgage obligations. Factors affecting mortgage prepayments include,
among other things, the level of interest rates, general economic and social
conditions and the location and age of the mortgages. High interest rate
mortgages are more likely to be prepaid than lower-rate mortgages; consequently,
the effective maturities of mortgage-related obligations that pass-through
payments of higher-rate mortgages are likely to be shorter than those of
obligations that pass-through payments of lower-rate mortgages. If such
prepayment of mortgage-related securities in which the Portfolio invests occurs,
the Portfolio may have to invest the proceeds in securities with lower yields.

The Government National Mortgage Association (GNMA) is a US Government
corporation within the Department of Housing and Urban Development, authorized
to guarantee, with the full faith and credit of the US Government, the timely
payment of principal and interest on securities issued by institutions approved
by GNMA (such as savings and loan institutions, commercial banks and mortgage
bankers) and backed by pools of Federal Housing Administration insured or
Veterans Administration guaranteed residential mortgages. These securities
entitle the holder to receive all interest and principal payments owed on the
mortgages in the pool, net of certain fees, regardless of whether or not the
mortgagors actually make the payments. Other government-related issuers of
mortgage-related securities include the Federal National Mortgage Association
(FNMA), a government-sponsored corporation subject to general regulation by the
Secretary of Housing and Urban Development but owned entirely by private
stockholders, and the Federal Home Loan Mortgage Corporation (FHLMC), a
corporate instrumentality of the US Government created for the purpose of
increasing the availability of mortgage credit for residential housing that is
owned by the twelve Federal Home Loan Banks. FHLMC issues Participation
Certificates (PCs), which represent interests in mortgages from FHLMC's national
portfolio. FHLMC guarantees the timely payment of interest and ultimate
collection of principal, but PCs are not backed by the full faith and credit of
the US Government. Pass-through securities issued by FNMA are backed by
residential mortgages purchased from a list of approved seller/servicers and are
guaranteed as to timely payment of principal and interest by FNMA, but are not
backed by the full faith and credit of the US Government.

Commercial banks, savings and loan institutions, private mortgage insurance
companies, mortgage bankers and other secondary market issuers also create
pass-through securities based on pools of conventional residential mortgage
loans. Securities created by such non-governmental issuers may offer a higher
rate of interest than government-related securities; however, timely payment of
interest and principal may or may not be supported by insurance or guarantee
arrangements, and there can be no assurance that the private issuers can meet
their obligations.

                                       8

Collateralized Mortgage Obligations. Seligman Income Portfolio may invest in
Collateralized Mortgage Obligations (CMOs), including certain CMOs that have
elected to be treated as Real Estate Mortgage Investment Conduits (REMICs). CMOs
are fixed-income securities collateralized by pooled mortgages and separated
into short-, medium-, and long-term positions (called tranches). Tranches pay
different rates of interest depending upon their maturity. CMOs may be
collateralized by (a) pass through securities issued or guaranteed by GNMA, FNMA
or FHLMC, (b) unsecuritized mortgage loans insured by the Federal Housing
Administration or guaranteed by the Department of Veteran's Affairs, (c)
unsecuritized conventional Mortgages, (d) other mortgage related securities or
(e) any combination thereof.

Each tranche of a CMO is issued at a specific coupon rate and has a stated
maturity. As the payments on the underlying mortgage loans are collected, the
CMO issuer generally pays the coupon rate of interest to the holders of each
tranche. In a common structure referred to as a "Pay" CMO, all scheduled and
unscheduled principal payments generated by the collateral, as loans are repaid
or prepaid, go initially to investors in the first tranches. Investors in later
tranches do not start receiving principal payments until the prior tranches are
paid in full. Sometimes, CMOs are structured so that the prepayment and/or
market risks are transferred from one tranche to another.

Most CMOs are issued by Federal agencies. However, the only CMOs backed by the
full faith and credit of the US Government are CMOs collateralized by
pass-through securities guaranteed by GNMA. All CMOs are subject to reinvestment
risk; that is, as prepayments on the underlying pool of mortgages increase, the
maturity of the tranches in the CMO will decrease. As a result, the Portfolio
may have to invest the proceeds that were invested in such CMOs in securities
with lower yields. Factors affecting reinvestment risk include the level of
interest rates, general economic and social conditions and the location and age
of the mortgages.

Repurchase Agreements

Each Portfolio may hold cash or cash equivalents and may enter into repurchase
agreements with respect to securities; normally repurchase agreements relate to
money market obligations backed by the full faith and credit of the US
Government. Repurchase agreements are transactions in which an investor (e.g.,
any of the Fund's Portfolios) purchases a security from a bank, recognized
securities dealer, or other financial institution and simultaneously commits to
resell that security to such institution at an agreed upon price, date and
market rate of interest unrelated to the coupon rate or maturity of the
purchased security. A repurchase agreement thus involves the obligation of the
bank or securities dealer to pay the agreed upon price on the date agreed to,
which obligation is in effect secured by the value of the underlying security
held by the Portfolio. Repurchase agreements could involve certain risks in the
event of bankruptcy or other default by the seller, including possible delays
and expenses in liquidating the securities underlying the agreement, decline in
value of the underlying securities and loss of interest. Although repurchase
agreements carry certain risks not associated with direct investments in
securities, each Portfolio intends to enter into repurchase agreements only with
financial institutions believed to present minimum credit risks in accordance
with guidelines established by the investment manager. The investment manager
has implemented measures to review and monitor the creditworthiness of such
institutions. The Portfolios will invest only in repurchase agreements
collateralized in an amount at least equal at all times to the purchase price
plus accrued interest. Repurchase agreements usually are for short periods, such
as one week or less, but may be for longer periods. No Portfolio will enter into
a repurchase agreement with a maturity of more than seven days if, as a result,
more than 15% of the value of its net assets would then be invested in such
repurchase agreements and other illiquid investments.

When-Issued and Forward Commitment Securities

Seligman Bond Portfolio and Seligman High-Yield Bond Portfolio may purchase
securities on a when-issued or forward commitment basis. Settlement of such
transactions (i.e., delivery of securities and payment of purchase price)
normally takes place within 45 days after the date of the commitment to
purchase. Although Seligman Bond Portfolio and Seligman High-Yield Bond
Portfolio will purchase a security on a when-issued or forward commitment basis
only with the intention of actually acquiring the securities, the Portfolios may
sell these securities before the purchase settlement date if it is deemed
advisable.

                                       9
<PAGE>


At the time a Portfolio enters into such a commitment both payment and interest
terms will be established prior to settlement; there is a risk that prevailing
interest rates on the settlement date will be greater than the interest rate
terms established at the time the commitment was entered into. When-issued and
forward commitment securities are subject to changes in market value prior to
settlement based upon changes, real or anticipated, in the level of interest
rates or creditworthiness of the issuer. If a Portfolio remains substantially
fully invested at the same time that it has purchased securities on a
when-issued or forward commitment basis, the market value of that Portfolio's
assets may fluctuate more than otherwise would be the case. For this reason,
accounts for each Portfolio will be established with the Fund's custodian
consisting of cash and/or liquid high-grade debt securities equal to the amount
of each Portfolio's when-issued or forward commitment obligations; these
accounts will be valued each day and additional cash and/or liquid high-grade
debt securities will be added to an account in the event that the current value
of the when-issued or forward commitment obligations increase. When the time
comes to pay for when-issued or forward commitment securities, a Portfolio will
meet its respective obligations from then available cash flow, sale of
securities held in the separate account, sale of other securities, or from the
sale of the when-issued or forward commitment securities themselves (which may
have a value greater or less than a Portfolio's payment obligations). Sale of
securities to meet when-issued and forward commitment obligations carries with
it a greater potential for the realization of capital gain or loss.

Short Sales

Each of the Global Portfolios may sell securities short "against-the-box." A
short sale "against-the-box" is a short sale in which the Portfolio 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
issue as, and equal in amount to, the securities sold short.

Lending of Portfolio Securities

Other than Seligman Cash Management Portfolio, each of the Portfolios may lend
portfolio securities to broker/dealers, banks or other institutional borrowers,
provided that securities loaned by each of the Global Portfolios may not exceed
33 1/3% of the Portfolios' total assets taken at market value. The Portfolios
will not lend portfolio securities to any institutions affiliated with the Fund.
The borrower must maintain with the Fund's custodian bank 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 lending
Portfolio an amount equal to any dividends or interest paid on the securities.
The lending Portfolio may invest the collateral and earn additional income or
receive an agreed upon amount of interest income from the borrower. Loans made
by the Portfolios will generally be short-term. Loans are subject to termination
at the option of the lending Portfolio or the borrower. The lending Portfolio
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 lending Portfolio does not have the right to
vote securities on loan, but would terminate the loan and regain the right to
vote if that were considered important with respect to the investment. The
lending Portfolio may lose money if a borrower defaults on its obligation to
return securities and the value of the collateral held by the lending Portfolio
is insufficient to replace the loaned securities. In addition, the lending
Portfolio is responsible for any loss that might result from its investment of
the borrower's collateral.

Borrowing

Except as noted below, a Portfolio may borrow money only from banks for
temporary purposes (but not for the purpose of purchasing portfolio securities)
in an amount not to exceed 10% of the value of the total assets of that
Portfolio. In addition, Seligman Frontier Portfolio, Seligman High-Yield Bond
Portfolio, Seligman Large-Cap Growth Portfolio, Seligman Large-Cap Value
Portfolio, and Seligman Small-Cap Value Portfolio will not purchase additional
portfolio securities if such Portfolios have outstanding borrowings in excess of
5% of the value of their total assets.

Seligman Capital Portfolio, Seligman Common Stock Portfolio, Seligman
Communications and Information Portfolio, Seligman Large-Cap Growth Portfolio,
Seligman Large-Cap Value Portfolio, and Seligman Small-Cap Value Portfolio may
from time to time borrow money in order to purchase securities. Borrowings may
be made only from banks and each of these Portfolios may not borrow in excess of
one-third of the market value of its assets, less liabilities other than such
borrowing, or pledge more than 10% (15% for Seligman Large-Cap Growth

                                       10
<PAGE>


Portfolio, Seligman Large-Cap Value Portfolio, and Seligman Small-Cap Value
Portfolio) of its total assets, taken at cost, to secure the borrowing. Current
asset value coverage of three times any amount borrowed by the respective
Portfolio is required at all times. Borrowed money creates an opportunity for
greater capital appreciation, but at the same time increases exposure to capital
risk. The net cost of any money borrowed would be an expense that otherwise
would not be incurred, and this expense will reduce the Portfolio's net
investment income in any given period. Any gain in the value of securities
purchased with money borrowed to an amount in excess of amounts borrowed plus
interest would cause the net asset value of the Portfolio's shares to increase
more than otherwise would be the case. Conversely, any decline in the value of
securities purchased to an amount below the amount borrowed plus interest would
cause the net asset value to decrease more than would otherwise be the case.

Each of the Global Portfolios may from time to time borrow money for temporary,
extraordinary or emergency purposes and may invest the funds in additional
securities. Borrowings for the purchase of securities will not exceed 5% of the
Portfolio's total assets and will be made at prevailing interest rates.

Except as otherwise specifically noted above, each of the Fund's Portfolios'
investment strategies are not fundamental and the Fund, with the approval of the
Board of Directors, may change such strategies without the vote of a majority of
a Portfolio's outstanding voting securities.

Fund Policies

The Fund is subject to fundamental policies that place restrictions on certain
types of investments. Except as otherwise indicated below, restrictions No. 1
through 9 may not be changed without the affirmative vote of the holders of a
majority of a Portfolio's outstanding voting securities; restrictions No. 10
through 16 may be changed by the Fund's Board of Directors without such a vote.
Under these restrictions, none of the Portfolios may:

1.   Borrow money, except from banks for temporary purposes (but not for the
     purpose of purchasing portfolio securities) in an amount not to exceed 10%
     (15% for Seligman Large-Cap Growth Portfolio, Seligman Large-Cap Value
     Portfolio, and Seligman Small-Cap Value Portfolio) of the value of the
     total assets of the Portfolio; except that Seligman Capital Portfolio,
     Seligman Common Stock Portfolio, Seligman Communications and Information
     Portfolio, Seligman Large-Cap Growth Portfolio, Seligman Large-Cap Value
     Portfolio, and Seligman Small-Cap Value Portfolio may borrow to purchase
     securities provided that such borrowings are made only from banks, do not
     exceed one-third of the respective Portfolio's net assets (taken at market)
     and are secured by not more than 10% (15% for Seligman Large-Cap Growth
     Portfolio, Seligman Large-Cap Value Portfolio, and Seligman Small-Cap Value
     Portfolio) of such assets (taken at cost); except that Seligman Frontier
     Portfolio, Seligman High-Yield Bond Portfolio, Seligman Large-Cap Growth
     Portfolio, Seligman Large-Cap Value Portfolio and Seligman Small-Cap Value
     Portfolio will not purchase additional portfolio securities if it has
     outstanding borrowings in excess of 5% of the value of its total assets;
     and except that each of the Global Portfolios may borrow money from banks
     to purchase securities in amounts not in excess of 5% of its total assets.

2.   Mortgage, pledge or hypothecate any of its assets, except to secure
     borrowings permitted by paragraph 1 and provided that this limitation does
     not prohibit escrow, collateral or margin arrangements in connection with
     (a) the purchase or sale of covered options (including stock index
     options), (b) the purchase or sale of interest rate or stock index futures
     contracts or options on such contracts by any of the Fund's Portfolios
     otherwise permitted to engage in transactions involving such instruments or
     (c) in connection with the Fund's purchase of fidelity insurance and errors
     and omissions insurance, and provided, further, that Seligman High-Yield
     Bond Portfolio may mortgage, pledge or hypothecate its assets, but the
     value of such encumbered assets may not exceed 10% of that Portfolio's net
     asset value. This investment restriction No. 2 may be changed, with respect
     to Seligman High-Yield Bond Portfolio, by the Fund's Board of Directors.

3.   Make "short" sales of securities (except that each of the Global Portfolios
     may make short sales "against-the-box"), or purchase securities on "margin"
     except for short-term credits necessary for the purchase or sale of
     securities, provided that for purposes of this limitation, initial and
     variation payments or deposits in connection with transactions involving
     interest rate or stock index futures contracts and options on such
     contracts by any Portfolio permitted to engage in transactions involving
     such instruments will not be deemed to be the purchase of securities on
     margin.

                                       11
<PAGE>


4.   With respect to 75% of its securities portfolio (or 100% of its securities
     portfolio, in the case of Seligman High-Yield Bond Portfolio), purchase
     securities of any issuer if immediately thereafter more than 5% of its
     total assets valued at market would be invested in the securities of any
     one issuer, other than securities issued or guaranteed by the US
     Government, its agencies or instrumentalities; or buy more than 10% of the
     voting securities of any one issuer.

5.   Invest more than 25% of the market value of its total assets in securities
     of issuers in any one industry (except securities issued or guaranteed by
     the US Government, its agencies or instrumentalities), provided that for
     the purpose of this limitation, mortgage-related securities do not
     constitute an industry; provided further that Seligman Communications and
     Information Portfolio will invest at least 65% of the value of its total
     assets in securities of companies principally engaged in the
     communications, information and related industries, except when investing
     for temporary defensive purposes; and provided further that Seligman Cash
     Management Portfolio may invest more than 25% of its gross assets: (i) in
     the banking industry; (ii) in the personal credit institution or business
     credit institution industries; or (iii) in any combination of (i) and (ii).

6.   Purchase or hold any real estate, except that Seligman Bond Portfolio,
     Seligman Common Stock Portfolio, Seligman Income Portfolio, Seligman
     Large-Cap Growth Portfolio, Seligman Large-Cap Value Portfolio, Seligman
     Small-Cap Value Portfolio, and each of the Global Portfolios may engage in
     transactions involving securities secured by real estate or interests
     therein, and each of the Global Portfolios may purchase securities issued
     by companies or investment trusts that invest in real estate or interests
     therein.

7.   Purchase or sell commodities and commodity futures contracts; except that
     the Board of Directors may authorize any Portfolio other than Seligman Cash
     Management Portfolio and Seligman High-Yield Bond Portfolio to engage in
     transactions involving interest rate and/or stock index futures and related
     options solely for the purposes of reducing investment risk and not for
     speculative purposes.

8.   Underwrite the securities of other issuers, provided that the disposition
     of investments otherwise permitted to be made by any Portfolio (such as
     investments in securities that are not readily marketable without
     registration under the 1933 Act and repurchase agreements with maturities
     in excess of seven days) will not be deemed to render a Portfolio engaged
     in an underwriting investment if not more than 10% of the value of such
     Portfolio's total assets (taken at cost) would be so invested and except
     that in connection with the disposition of a security a Portfolio may be
     deemed to be an underwriter as defined in the 1933 Act.

9.   Make loans, except loans of securities, provided that purchases of notes,
     bonds or other evidences of indebtedness, including repurchase agreements,
     are not considered loans for purposes of this restriction; provided further
     that each of the Global Portfolios may not make loans of money or
     securities other than (a) through the purchase of securities in accordance
     with its 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.

10.  Purchase illiquid securities for any Portfolio including repurchase
     agreements maturing in more than seven days and securities that cannot be
     sold without registration or the filing of a notification under Federal or
     state securities laws, if, as a result, such investment would exceed 15% of
     the value of such Portfolio's net assets.

11.  Invest in oil, gas or other mineral exploration or development programs;
     provided, however, that this investment restriction shall not prohibit a
     Portfolio from purchasing publicly-traded securities of companies engaging
     in whole or in part in such activities.

12.  Purchase securities of any other investment company, except in connection
     with a merger, consolidation, acquisition or reorganization or for the
     purpose of hedging the Portfolio's obligations under its deferred
     compensation plan for directors, and except to the extent permitted by
     Section 12 of the 1940 Act.

13.  Purchase securities of companies which, together with predecessors, have a
     record of less than three years' continuous operation, if as a result of
     such purchase, more than 5% of such Portfolio's net assets would then be
     invested in such securities; except that Seligman Communications and
     Information Portfolio, Seligman Frontier Portfolio, each of the Global
     Portfolios and Seligman High-Yield Bond Portfolio may each invest no more
     than 5% of total assets, at market value, in securities of companies which,
     with their predecessors, have

                                       12
<PAGE>


     been in operation less than three continuous years, excluding from this
     limitation securities guaranteed by a company that, including predecessors,
     has been in operation at least three continuous years. This restriction
     does not apply to Seligman Large-Cap Growth Portfolio, Seligman Large-Cap
     Value Portfolio or Seligman Small-Cap Value Portfolio.

14.  Purchase securities of companies for the purpose of exercising control.

15.  Purchase securities from or sell securities to any of its officers or
     Directors, except with respect to its own shares and as permissible under
     applicable statutes, rules and regulations. In addition, Seligman
     High-Yield Bond Portfolio may not purchase or hold the securities of any
     issuer if, to its knowledge, directors or officers of the Fund individually
     owning beneficially more than 0.5% of the securities of that issuer own in
     the aggregate more than 5% of such securities.

16.  Invest more than 5% of the value of its net assets, valued at the lower of
     cost or market, in warrants, of which no more than 2% of net assets may be
     invested in warrants and rights not listed on the New York or American
     Stock Exchange. For this purpose, warrants acquired by the Fund in units or
     attached to securities may be deemed to have been purchased without cost.

If a percentage restriction is adhered to at the time of an investment, a later
increase or decrease in such percentage resulting from a change in the value of
assets will not constitute a violation of such restriction. In order to permit
the sale of the Fund's shares in certain states, the Fund may make commitments
more restrictive than the investment restrictions described above. Should the
Fund determine that any such commitment is no longer in the best interest of the
Fund it will revoke the commitment by terminating sales in the state involved.
The Fund also intends to comply with the diversification requirements under
Section 817(h) of the Internal Revenue Code of 1986, as amended. For a
description of these requirements, see the separate account prospectuses or
disclosure documents of the participating insurance companies.

Under the 1940 Act, a "vote of a majority of the outstanding voting securities"
of the Fund or of a particular Portfolio means the affirmative vote of the
lesser of (1) more than 50% of the outstanding shares of the Fund or of such
Portfolio or (2) 67% or more of the shares of the Fund or of such Portfolio
present at a shareholder's meeting if more than 50% of the outstanding shares of
the Fund or of such Portfolio are represented at the meeting in person or by
proxy.

Temporary Defensive Position

Each Portfolio may, from time to time, take a temporary defensive position in
seeking to minimize extreme volatility caused by adverse market, economic, or
other conditions, or in anticipation of significant withdrawals. When the
investment manager believes that market conditions warrant a temporary defensive
position, a Portfolio 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. A Portfolio'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. In addition, the High-Yield Bond Portfolio may
also invest in high-yield, medium and lower quality corporate notes.

Portfolio Turnover

The portfolio turnover rates for each Portfolio are calculated by dividing the
lesser of purchases or sales of portfolio securities for the year by the monthly
average of the value of the portfolio securities owned during the year.
Securities whose maturity or expiration date at the time of acquisition were one
year or less are excluded from the calculation. The portfolio turnover rates for
each Portfolio (except Seligman Cash Management Portfolio) for the years ended
December 31, 1999 and, if applicable, 1998 were as follows:

(1) For the Fund's year ended December 31, 1999. Effective Janaury 21, 2000, the
    per meeting fee for Directors was increased by $1,000, which is allocated
    among all the Funds in the Fund Complex.

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

(3) Deferred.
</TABLE>


The Fund has a compensation arrangement under which outside directors may elect
to defer receiving their fees. The Fund has adopted a deferred compensation plan
under which a director who has elected deferral of his or her fees may choose a
rate of return equal to either (1) the interest rate on short-term Treasury
Bills, or (2) the rate of return on the shares of certain of the investment
companies advised by J. & W. Seligman & Co. Incorporated (Seligman), as
designated by the director. The cost of such fees and earnings is included in
the directors' fees and expenses, and the accumulated balance thereof is
included in other liabilities in the Fund's financial statements.

                                       18
<PAGE>


The total amount of deferred compensation (including earnings) payable in
respect of the Fund to Mr. Whitson as of December 31, 1999 was $36,159. Messrs.
Merow and Pitney no longer defer current compensation; however, they have
accrued deferred compensation (including earnings) in the amounts of $17,746 and
$2,589, respectively, as of December 31, 1999.



The Fund may, but is not obligated to, purchase shares of the other funds in the
Seligman Group of investment companies to hedge its obligations in connection
with the Fund's deferred compensation plan (except Seligman Cash Management
Portfolio, which is obligated to purchase shares of the Seligman Group of
investment companies).


Code of Ethics

Seligman, Seligman Advisors, Inc. (Seligman Advisors), their subsidiaries and
affiliates, and the Seligman Group of Investment Companies have adopted a Code
of Ethics that sets forth the circumstances under which officers, directors and
employees (collectively, Employees) are permitted to engage in personal
securities transactions. 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 Director of Compliance, and sets forth a procedure of identifying,
for disciplinary action, those individuals who violate the Code of Ethics. The
Code of Ethics prohibits Employees (including all investment team members) from
purchasing or selling any security or an equivalent security that is being
purchased or sold by any client, or where the Employee intends, knows of
another's intention, to purchase or sell the security on behalf of a client. The
Code also prohibits all Employees from acquiring securities in a private
placement or in an initial or secondary public offering unless an exemption has
been obtained from Seligman's Director of Compliance.

The Code of Ethics 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) that the portfolio manager or investment team
manages; (2) each Employee from engaging in short-term trading (a purchase and
sale or vice-versa within 60 days); and (3) each member of an investment team
from engaging in short sales of a security if, at that time, any client managed
by that team has a long position in that security. Any profit realized pursuant
to any of these prohibitions must be disgorged.

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 Employees are also required to disclose all
securities beneficially owned by them upon commencement of employment and at the
end of each calendar year.

A copy of the Code of Ethics is on public file with, and is available upon
request from, the Securities and Exchange Commission (SEC). You can access it
through the SEC's Internet site, http://www.sec.gov.

Under a Subadvisory Agreement dated July 1, 1998, HIML furnishes investment
advice, research and assistance with respect to the Seligman Global Smaller
Companies Portfolio's non-US investments. Prior to March 31, 2000, HIML also
served as a subadviser with respect to each of the other Global Portfolios.

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.

HIML receives a fee from Seligman, equal to an annual rate of .50% of the
Seligman Global Smaller Companies Portfolio's average daily net assets under the
supervision of HIML. The Subadvisory Agreement will continue until December 31,
2000 and from year to year thereafter (1) if such continuance is approved in the
manner required by the 1940 Act (by a vote of a majority of the Board of
Directors or of the outstanding voting securities of the Portfolio and by a vote
of a majority of the Directors who are not parties to the Subadvisory Agreement
or interested persons of any such party) and (2) HIML shall not have notified
Seligman in writing at least 60 days prior to such December 31 or prior to
December 31 of any year thereafter that it does not desire such continuance. The
Subadvisory Agreement may be terminated at any time by the Fund, on 60 days
written notice to HIML. The Subadvisory Agreement will terminate automatically
in the event of its assignment or upon the termination of the relevant
Management Agreement.

The Management Agreements (and Subadvisory Agreement, in the case of the
Seligman Global Smaller Companies Portfolio) provide that Seligman (and HIML, in
the case of the Seligman Global Smaller Companies Portfolio) will not be liable
to the Fund for any error of judgment or mistake of law, or for any loss arising
out of any investment, or for any act or omission in performing their duties
under the Management Agreements (or Subadvisory Agreement), except for willful
misfeasance, bad faith, gross negligence, or reckless disregard of their
obligations and duties under the Management Agreements (or Subadvisory
Agreement).

The Fund pays all its expenses other than those assumed by Seligman or HIML,
including brokerage commissions, fees and expenses of independent attorneys and
auditors, taxes and governmental fees, including fees and expenses of qualifying
the Fund and its shares under Federal securities laws, 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, fees and expenses of
Directors of the Fund not employed by or serving as a Director of Seligman or
its affiliates, insurance premiums and extraordinary expenses such as litigation
expenses.

The Management Agreement with respect to Seligman Bond Portfolio, Seligman
Capital Portfolio, Seligman Cash Management Portfolio, Seligman Common Stock
Portfolio and Seligman Income Portfolio was approved by the Board of Directors
on September 30, 1988 and by shareholders at a Special Meeting held on December
16, 1988. The Management Agreement with respect to the Seligman International
Growth Portfolio was approved by the Board of Directors on March 18, 1993. The
Management Agreements with respect to Seligman Communications and Information
Portfolio, Seligman Frontier Portfolio, and Seligman Global Smaller Companies
Portfolio were approved by the Board of Directors on July 21, 1994. The
Management Agreement with respect to Seligman High-Yield Bond Portfolio was
approved by the Board of Directors on March 16, 1995. The Management Agreement
with respect to Seligman Global Growth Portfolio and Seligman Global Technology
Portfolio was approved by the Board of Directors on March 21, 1996. The
Management Agreement with respect to Seligman Large-Cap Value Portfolio and
Seligman Small-Cap Value Portfolio was approved by the Board of Directors on
March 19, 1998 and by the sole shareholder of each Portfolio on April 30, 1998.
The Management Agreement with respect to Seligman Large-Cap Growth Portfolio was
approved by the Board of Directors on March 18, 1999. The Management Agreements
will continue in effect until December 31 of each year, with respect to each
Portfolio if (1) such continuance is approved in the manner required by the 1940
Act (by a vote of a majority of the Board of Directors or of the outstanding
voting securities of the Portfolios and by a vote of a majority of the Directors
who are not parties to the Management Agreements or interested persons of any
such party) and (2) Seligman shall not have notified the Fund at least 60 days
prior to the anniversary date of the previous continuance that it does not
desire such continuance. The Management Agreements may be terminated at any time
with respect to any or all Portfolios, by the Fund, without penalty, on 60 days
written notice to Seligman. Seligman may terminate the Management Agreements at
any time upon 60 days written notice to the Fund. The Management Agreements will
terminate

                                       21

automatically in the event of their assignment. The Fund has agreed to
change its name upon termination of the Management Agreements if continued use
of the name would cause confusion in the context of Seligman's business.



Principal Underwriter

Seligman Advisors, an affiliate of Seligman, 100 Park Avenue, New York, New York
10017, acts a general distributor of the shares of the Portfolios and of each of
the mutual funds in the Seligman Group. Seligman Advisors is an "affiliated
person" (as defined in the 1940 Act) of Seligman, which is itself an affiliated
person of the Fund. Those individuals identified above under "Management
Information" as directors or officers of both the Fund and Seligman Advisors are
affiliated persons of both entities.



Services Provided by the Investment Manager

Pursuant to Management Agreements between the Fund and Seligman in respect of
the Portfolios and subject to the control of the Board of Directors, Seligman
manages the investment of the assets of the Fund's Portfolios, including making
purchases and sales of portfolio securities consistent with each Portfolio's
investment objectives and policies, and administers the Fund's business and
other affairs. Seligman provides the Fund with such office space, administrative
and other services and executive and other personnel as are necessary for Fund
operations. Seligman pays all of the compensation of directors and/or officers
of the Fund who are employees or consultants of Seligman except as otherwise
provided by HIML.

Service Agreements

There are no other management-related service contracts under which services are
provided to the Fund.



Other Investment Advice

No person or persons, other than directors, officers, or employees of Seligman,
or HIML with respect to Seligman Global Smaller Companies Portfolio, regularly
advise the Fund's Portfolios with respect to their investments.

Rule 12b-1 Plan

Each Portfolio has adopted a Shareholder Servicing and Distribution Plan (12b-1
Plan) with respect to the Portfolio's Class 2 shares in accordance with Section
12(b) of the 1940 Act and Rule 12b-1 thereunder.

Under the 12b-1 Plan, Class 2 shares of each Portfolio pay monthly to Seligman
Advisors, an annual shareholder servicing and distribution fee of up to 0.25% of
the average daily net assets attributable to Class 2 shares. Seligman Advisors
uses this fee to make payments to participating insurance companies or their
affiliates for services that the participating insurance companies provide to
Contract owners of Class 2 shares including, but not limited to, (1) the
printing and delivering of prospectuses, statements of additional information,
shareholder reports, proxy statements and marketing materials related to the
Portfolios to current Contract owners, (2) providing facilities to answer
questions from current Contract owners about the Portfolios, (3) receiving and
answering correspondence, (4) providing information to Seligman and to Contract
owners with respect to shares of the Portfolios attributable to Contract owner
Accounts, (5) complying with federal and state securities laws pertaining to the
sale of shares of the Portfolios, (6) assisting Contract owners in completing
application forms and selecting dividend and other Account options, and (7)
other distribution related services. The participating insurance companies will
also provide such office space and equipment, telephone facilities, and
personnel as may be reasonably necessary or beneficial in order to provide such
services to owners.

Seligman, in its sole discretion, may also make similar payments to Seligman
Advisors and participating insurance companies from its own resources, which may
include the management fee that Seligman receives from the Portfolios. Payments
made by the Portfolios under the 12b-1 Plan are intended to be used to encourage
sales of Class 2 shares to Contract owners, as well as to discourage redemptions
and/or exchanges.

Fees paid by each Portfolio under the 12b-1 Plan for Class 2 shares may not be
used to pay expenses incurred solely in respect of Class 1 shares or any other
Seligman fund.


                                       22
<PAGE>

The amounts expended by participating insurance companies in any one year with
respect to Class 2 shares of a Portfolio may exceed the 12b-1 fees paid by the
Portfolio in that year. Each Portfolio's 12b-1 Plan permits expenses incurred by
participating insurance companies in respect of Class 2 shares in one fiscal
year to be paid from Class 2 12b-1 fees in any other fiscal year; however, in
any fiscal year the Portfolios are not obligated to pay any 12b-1 fees in excess
of those described above.



The 12b-1 Plan was approved with respect to the Class 2 shares of each Portfolio
on March 16, 2000 by the Board of Directors, including a majority of the
Directors who are not "interested persons" (as defined in the 1940 Act) of the
Fund and who had no direct or indirect financial interest in the operation of
the 12b-1 Plan or in any agreement related to the Plan (Qualified Directors).
The 12b-1 Plan will continue in effect until December 31 of each year, so long
as such continuance is approved annually by a majority vote of both the
Directors and the Qualified Directors of the Fund, cast in person at a meeting
called for the purpose of voting on such approval. The 12b-1 Plans may not be
amended to increase materially the amounts payable to Seligman Advisors without
the approval of a majority of the outstanding voting securities of the relevant
class. 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 require that the Treasurer of the Fund shall provide to the
Directors, and the Directors shall review, at least quarterly, a written report
of the amounts expended (and purposes therefor) under the Plans. Rule 12b-1 also
requires that the selection and nomination of Directors who are not "interested
persons" of the Fund be made by such disinterested Directors. The 12b-1 Plans
will be reviewed by the Directors annually.



No Class 2 shares were outstanding during the year ended December 31, 1999, and
no Portfolio paid any fees to Seligman Advisors under the 12b-1 Plan.



                    Brokerage Allocation and Other Practices

Portfolio Transactions

In directing transactions involving exchange-listed securities, Seligman (or in
the case of Seligman Global Smaller Companies Portfolio, Seligman or HIML) will
seek the most favorable price and execution, and consistent with that policy may
give consideration to the research, statistical, and other services furnished by
brokers or dealers to Seligman or HIML for its use. In addition, Seligman and
HIML are authorized to place orders with brokers who provide supplemental
investment and market research and security and economic analysis, although the
use of such brokers may result in a higher brokerage charge to a Portfolio than
the use of brokers selected solely on the basis of seeking the most favorable
price and execution although such research and analysis received may be useful
to Seligman or HIML in connection with their services to other clients as well
as to the Portfolios.

Portfolio transactions for Seligman Bond Portfolio, Seligman Cash Management
Portfolio and Seligman High-Yield Bond Portfolio, which invest in debt
securities generally traded in the over-the-counter market, and transactions by
any of the other Portfolios in debt securities traded on a "principal basis" in
the over-the-counter market are normally directed by Seligman or HIML to dealers
in the over-the-counter market acting as principal, except dealers with which
their directors or officers are affiliated.

Brokerage commissions of each Portfolio (except Seligman Bond Portfolio,
Seligman Cash Management Portfolio and Seligman High-Yield Bond Portfolio) for
the years 1999, and if applicable, 1998 and 1997, are set forth in the following
table:

*   Commissions paid from May 1, 1999 (commencement of operations).
**  Commissions paid from May 1, 1998 (commencement of operations).

The amount of brokerage commissions paid by Seligman Capital Portfolio has
increased materially from 1997 due to the Portfolio's increase in portfolio
turnover and the Portfolio's increase in portfolio transactions on public
exchanges as opposed to over-the-counter markets.

Commissions

For the years ended December 31, 1999, 1998 and 1997, the Fund did not execute
any portfolio transactions with, and therefore did not pay any commissions to,
any broker affiliated with either the Fund, Seligman, HIML, or Seligman
Advisors.

Brokerage Selection

Consistent with the rules of the National Association of Securities Dealers,
Inc. and other applicable laws, and subject to seeking the most favorable price
and execution available and such other policies as the Directors may determine,
Seligman or HIML may consider sales of the other Funds in the Seligman Group as
a factor in the selection of brokers or dealers to execute portfolio
transactions for the Fund.

Directed Brokerage

During the Fund's year ended December 31, 1999, neither the Fund, Seligman, nor
HIML, through an agreement or understanding with a broker, or otherwise through
an internal allocation procedure, directed any of the Fund's brokerage
transactions to a broker because of research services provided.

Regular Broker-Dealers

During the Fund's year ended December 31, 1999, the Fund 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

The Fund is authorized to issue, create and classify shares of capital stock in
separate series without further action by shareholders. The Fund presently has
fifteen separate series of common stock, each of which maintains a separate
investment portfolio, designated as follows: Seligman Bond Portfolio, Seligman
Capital Portfolio, Seligman Cash Management Portfolio, Seligman Common Stock
Portfolio, Seligman Communications

                                       24
<PAGE>


and Information Portfolio, Seligman Frontier Portfolio, Seligman Global Growth
Portfolio, Seligman Global Smaller Companies Portfolio, Seligman Global
Technology Portfolio, Seligman International Growth Portfolio, Seligman
High-Yield Bond Portfolio, Seligman Income Portfolio, Seligman Large-Cap Growth
Portfolio, Seligman Large-Cap Value Portfolio, and Seligman Small-Cap Value
Portfolio. Shares of capital stock of each Portfolio have a par value of $.001
and are divided into two classes, designated as Class 1 common stock and Class 2
common stock. Each share of a Fund's Class 1 and Class 2 common stock is equal
as to earnings, assets and voting privileges, except that each class bears its
own separate shareholder servicing and, potentially, certain other class
expenses and has exclusive voting rights with respect to any matter to which a
separate vote of any class is required by the 1940 Act or Maryland law. The
Series has adopted a Plan (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. Shares have non-cumulative voting rights for the election of directors.
Each outstanding share will be fully paid and non-assessable, and freely
transferable. There are no liquidation, conversion or prescriptive rights.

In accordance with current policy of the SEC, holders of the Accounts have the
right to instruct the applicable participating insurance companies as to voting
of Fund shares held by such Accounts on all matters to be voted on by Fund
shareholders. Such rights may change in accordance with changes in policies of
the SEC. Voting rights of the participants in the Accounts of participating
insurance companies are more fully set forth in the prospectuses or disclosure
documents relating to those Accounts, which should be read together with each
Portfolio's Prospectus. The Directors of the Fund have authority to create
additional portfolios and to classify and reclassify shares of capital stock
without further action by shareholders, and additional series may be created in
the future. Under Maryland corporate law, the Fund is not required to hold
annual meetings and it is the intention of the Fund's Directors not to do so.
However, special meetings of shareholders will be held for action by
shareholders as may be required by the 1940 Act, the Fund's Articles of
Incorporation and By-Laws, or Maryland corporate law.

Other Securities

The Fund has no authorized securities other than the above-mentioned common
stock.

                   Purchase, Redemption, and Pricing of Shares

Purchase of Shares

The Fund's Portfolios are offering their shares only to the Accounts of
participating insurance companies to fund benefits of the Contracts. The
Accounts may invest in shares of the Portfolios in accordance with allocation
instructions received from the owners of the Contracts. Such allocations rights
and information on how to purchase or surrender a Contract, as well as sales
charges and other expenses imposed by the Contracts on their owners, are further
described in the separate prospectuses and disclosure documents issued by the
participating insurance companies and accompanying each Portfolio's Prospectus.
The Fund reserves the right to reject any order for the purchase of shares of
the Fund's Portfolios.

Offering Price

The net asset value per share of each Portfolio is determined as of the close of
regular trading on the New York Stock Exchange (NYSE) (normally, 4:00 p.m.
Eastern time) each day that the NYSE is open. Currently, the NYSE is 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.


It is the policy of Seligman Cash Management Portfolio to use its best efforts
to maintain a constant per share price equal to $1.00. Instruments held by
Seligman Cash Management Portfolio are valued on the basis of amortized cost.
This involves valuing an instrument at its cost initially and, thereafter,
assuming a constant amortization to maturity of any discount or premium,
regardless of the impact of fluctuating interest rates on the market value of
the instrument. While this method provides certainty in valuation, it may result
in periods during

                                       25
<PAGE>

which the value, as determined by amortized cost, is higher or lower than the
price the Portfolio would receive if it sold the instrument.

The foregoing method of valuation is permitted by Rule 2a-7 adopted by the SEC.
Under this rule, Seligman Cash Management Portfolio must maintain an
average-weighted portfolio maturity of 90 days or less, purchase only
instruments having remaining maturities of 397 days or less, and invest only in
securities determined by the Fund's Directors to be of high quality with minimal
credit risks. In accordance with the rule, the Directors have established
procedures designed to stabilize, to the extent reasonably practicable, the
price per share as computed for the purpose of sales and redemptions of Seligman
Cash Management Portfolio at $1.00. Such procedures include review of the
portfolio holdings by Seligman Cash Management Portfolio and determination as to
whether the net asset value of Seligman Cash Management Portfolio, calculated by
using available market quotations or market equivalents, deviates from $1.00 per
share based on amortized cost. The rule also provides that the extent of any
deviation between the net asset value based upon available market quotations or
market equivalents, and $1.00 per share net asset value, based on amortized
cost, must be examined by the Directors. In the event that a deviation of .5 of
1% or more exists between the Portfolio's $1.00 per share net asset value and
the net asset value calculated by reference to market gestations, or if there is
any deviation which the Board of Directors believes would result in a material
dilution to shareholders or purchasers, the Board of Directors will promptly
consider what action, if any, should be initiated. Any such action may include:
selling portfolio instruments prior to maturity to realize capital gains or
losses or to shorten average portfolio maturity; withholding dividends or paying
distributions from capital or capital gains; redeeming shares in kind; or
establishing a net asset value per share by using available market quotations.

With respect to each of the Global Portfolios, portfolio securities, including
open short positions, 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 makers in
such securities. Any securities for which recent market quotations are not
readily available, including restricted securities, are valued at fair value
determined in accordance with procedures approved by the Board of Directors.
Short-term obligations with less than 60 days remaining to maturity are
generally valued at amortized cost. Short-term obligations with more than 60
days remaining to maturity will be valued at current market value until the
sixtieth day prior to maturity, and will then be valued on an amortized cost
basis based on the value on such date unless the Board of Directors 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
the Portfolio are determined as of such times. Foreign currency exchange rates
are also generally determined prior to the close of regular trading on the NYSE.
Occasionally, events affecting the value of such securities and such exchange
rates may occur between the times at which they are determined and the close of
regular trading on the NYSE, which will not be reflected in the computation of
net asset value. If during such periods events occur which materially affect the
value of such securities, the securities will be valued at their fair market
value as determined in accordance with procedures approved by the Board of
Directors.

For purposes of determining the net asset value per share of the Portfolio 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.

Purchase or redemption requests received by participating insurance companies by
the close of regular trading on the NYSE (normally, 4:00 p.m. Eastern time) are
effected at the applicable Portfolio's net asset value per share calculated on
the date such purchase or redemption requests are received.

Redemption in Kind

The procedures for redemption of Fund shares under ordinary circumstances are
set forth in each Portfolio's Prospectus. In unusual circumstances, payment may
be postponed, if the orderly liquidation of portfolio securities is prevented by
the closing of, or restricted trading on the NYSE during periods of emergency,
or such other periods as ordered by the SEC. It is not anticipated that shares
will be redeemed for other than cash or its equivalent. However, the Fund
reserves the right to pay the redemption price to the Accounts in whole or in
part, by a distribution in kind from the Fund's investment portfolio, in lieu of
cash, taking the securities at their value employed for determining such
redemption price, and selecting the securities in such manner as the Board of
Directors may deem fair and equitable. If shares are redeemed in this way,
brokerage costs will ordinarily be incurred by the Accounts in converting such
securities into cash.


                              Taxation of the Fund

Each Portfolio of the Fund intends to continue to qualify as a "regulated
investment company" under certain provisions of the Internal Revenue Code of
1986, as amended. Under such provisions, the Fund's Portfolios will be subject
to federal income tax only with respect to undistributed net investment income
and net realized capital gain. Each of the Fund's Portfolios will be treated as
a separate entity. Dividends on Seligman Cash Management Portfolio will be
declared daily and reinvested monthly in additional full and fractional shares
of Seligman Cash Management Portfolio; it is not expected that this Portfolio
will realize capital gains. Dividends and capital gain distributions from each
of the other Portfolios will be declared and paid annually and will be
reinvested at the net asset value of such shares of the Portfolio that declared
such dividend or capital gain distribution. Information regarding the tax
consequences of an investment in the Fund's Portfolios is contained in the
separate prospectuses or disclosure documents of the Accounts, which should be
read together with this SAI.


                                  Underwriters


Distribution of Securities

The Fund and Seligman Advisors are parties to a Distribution and Shareholder
Servicing Agreement, dated March 16, 2000, under which Seligman Advisors acts as
the exclusive agent for distribution of shares of the Portfolios. Seligman
Advisors accepts orders for the purchase of Portfolio shares, which are offered
continuously.


Compensation

Seligman Advisors, which is an affiliated person of Seligman, which is an
affiliated person of the Fund, did not receive any commissions or other
compensation from the Fund during the fiscal year ended December 31, 1999.


                         Calculation of Performance Data

From time to time the average annual total return and other total return data,
as well as yield, of one or more of the Portfolios may be included in
advertisements or information furnished to present or prospective Contract
owners. Total return and yield figures are based on each Portfolio's historical
performance and are not intended to indicate future performance. Average annual
total return and yield are determined in accordance with formulas specified by
the SEC.

The average annual total returns for each Portfolio are computed by assuming a
hypothetical initial investment of $1,000 in the Portfolio, and assuming that
all of the dividends and capital gain distributions paid by the Portfolio, if
any, are reinvested over the relevant time period. It is then assumed that at
the end of each period, the entire amount is redeemed. The average annual total
return is 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).

Annualized yield quotations (with respect to Seligman Bond Portfolio and
Seligman High-Yield Bond Portfolio) are computed by dividing each Portfolio's
net investment income per share earned during the 30-day period by the offering
price per share on the last day of the period. Income is computed by totaling
the dividends and interest earned on all portfolio investments during the 30-day
period and subtracting from that amount the total of all


                                       27
<PAGE>




recurring expenses incurred during the period. The 30-day yield is then
annualized on a bond-equivalent basis assuming semi-annual reinvestment and
compounding of net investment income. The annualized yield for the 30-day period
ended December 31, 1999 for Class 1 shares of Seligman Bond Portfolio and
Seligman High-Yield Bond Portfolio was 6.73% and 12.07%, respectively. The
average number of Class 1 shares of Seligman Bond Portfolio and Seligman
High-Yield Bond Portfolio was 557,563 and 2,727,751, respectively, which was the
average daily number of shares outstanding during the 30-day period that were
eligible to receive dividends. Yield quotations may be of limited use for
comparative purposes because they do not reflect charges imposed at the Account
level which, if included, would decrease the yield. There were no Class 2 shares
of Seligman Bond Portfolio or Seligman High-Yield Bond Portfolio outstanding
during the period shown, so no yield data is presented with respect to Class 2
shares.

The average annual total returns for each of the Portfolio's (except Seligman
Cash Management Portfolio and Seligman Large-Cap Growth Portfolio, which
commenced operations on May 1, 1999) Class 1 shares for the one-, five- and
ten-year periods ended December 31, 1999 (or for the period the Portfolio has
been in operation) are presented below. The returns for periods of less than one
year are not annualized. The average annual total return quotations may be of
limited use for comparative purposes because they do not reflect charges imposed
at the Account level which, if included, would decrease average annual total
return. There were no Class 2 shares outstanding during the periods shown, so no
performance data is presented with respect to Class 2 shares.

* Since inception.

The current yield of Seligman Cash Management Portfolio is computed by
determining the net change exclusive of capital changes in the value of a
hypothetical pre-existing account having a balance of 1 share at the beginning
of a seven-day calendar period, dividing the net change in account value by the
value of the account at the beginning of the period, and multiplying the return
over the seven-day period by 365/7. For purposes of the calculation, net change
in account value reflects the value of additional shares purchased with
dividends from the original share and dividends declared on both the original
share and any such additional shares, but does not reflect realized gains or
losses or unrealized appreciation or depreciation. Effective yield is computed
by annualizing the seven-day return with all dividends reinvested in additional
Portfolio shares.

The following are examples of the yield calculations for Class 1 shares of
Seligman Cash Management Portfolio for the seven-day period ended December 31,
1999. Yield quotations may be of limited use for comparative purposes because
they do not reflect charges imposed at the Account level which, if included,
would decrease the yield. There were no Class 2 shares of Seligman Cash
Portfolio outstanding during the period shown, so no yield data is presented
with respect to Class 2 shares.

MOODY'S INVESTORS SERVICE (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 the 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" indicates the highest
quality repayment ability of the rated issue.

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 RATINGS SERVICES (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 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
capacity to pay interest and repay principal although it is somewhat more
susceptible 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 an adequate 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."

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.

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.

The Seligman Complex:

     unnecessary.

     Mutual Gas Light Company, later part of Consolidated Edison.

     assets, and one of its oldest.

                    filed on April 28, 1998.)

                    Powers  of   Attorney.   (Incorporated   by   reference   to
                    Registrant's  Post-Effective Amendment No. 20 filed on April
                    17, 1997.)

Item 24. Persons Controlled by or Under Common Control with Registrant. None.

Item 25. Indemnification.  Reference  is  made  to the  provisions  of  Article
         Eleventh   of   Registrant's   Amended   and   Restated   Articles  of
         Incorporation filed as Exhibit 24(b)(1) of Registrant's Post-Effective
         Amendment  No. 22 to the  Registration  Statement  and  Article  IV of
         Registrant's Amended and Restated By-laws filed as Exhibit 24(b)(2) to
         Registrant's  Post-Effective  Amendment  No.  20 to  the  Registration
         Statement.

         Insofar  as   indemnification   for  liabilities   arising  under  the
         Securities  Act of 1933,  as amended,  may be permitted to  directors,
         officers and  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 OF AMENDMENT AND RESTATEMENT

                                       of

                            SELIGMAN PORTFOLIOS, INC.


     THIS IS TO CERTIFY that SELIGMAN  PORTFOLIOS,  INC., a Maryland corporation
having its principal office in Baltimore City, Maryland  (hereinafter called the
"Corporation"),  hereby  certifies to the State  Department of  Assessments  and
Taxation of Maryland that:

     FIRST: (a) The total number of shares of capital stock of the Seligman Bond
Portfolio  Class of the  Corporation  (the "Bond  Portfolio  Series")  which the
Corporation has authority to issue is 80,000,000  shares,  which were previously
classified by the Board of Directors of the Corporation as one class of the Bond
Portfolio Series.

     (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 Common  Stock of the Bond
Portfolio 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 stock  which the Bond  Portfolio
     Series  has  authority  to issue  is  80,000,000  shares  of  common  stock
     ("Shares")  of the par value of $.001 each having an aggregate par value of
     $80,000.  The  Common  Stock of the Bond  Portfolio  Series  shall have two
     subclasses of shares,  which shall be  designated  Class 1 Common Stock and
     Class 2 Common  Stock.  The number of  authorized  shares of Class 1 Common
     Stock and of Class 2 Common Stock of the Bond  Portfolio  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-half  of the  authorized  but
     unissued  shares of Common Stock of both  subclasses;  provided that at all
     times the aggregate  authorized,  issued and outstanding  shares of Class 1
     and Class 2 Common Stock of the Bond Portfolio  Series shall not exceed the
     authorized  number of shares of Common Stock of the Bond  Portfolio  Series
     (i.e., 80,000,000 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.  Each
     subclass of Common Stock of the Bond Portfolio  Series shall be referred to
     herein individually as a "Bond Portfolio Class" and collectively,  together
     with any further subclass or subclasses from time to time  established,  as
     the "Bond Portfolio Classes".

          (2) Each Bond Portfolio Class shall represent the same interest in the
     Corporation and have identical  voting,  dividend,  liquidation,  and other
     rights; provided, however, that notwithstanding anything in the Articles of
     Amendment and Restatement of the Corporation to the contrary:

               (A) Expenses  related solely to a particular Bond Portfolio Class
          (including, without limitation, shareholder servicing expenses under a
          Rule 12b-1  plan,  agreement  or other  arrangement,  which may differ
          between  the Bond  Portfolio  Classes)  shall  be  borne by that  Bond
          Portfolio  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
          Bond Portfolio Class.

               (B) As to any matter  with  respect  to which a separate  vote of
          either Bond Portfolio 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


                                       1
<PAGE>


          arrangement  referred to in subsection (A) above), such requirement as
          to a separate vote by the Bond Portfolio  Class shall apply in lieu of
          single  Bond  Portfolio  Class  voting,   and,  if  permitted  by  the
          Investment Company Act or any rules,  regulations or orders thereunder
          and the Maryland General  Corporation Law, the Bond Portfolio  Classes
          shall  vote  together  as a single  Bond  Portfolio  Class on any such
          matter  that  shall have the same  effect on each such Bond  Portfolio
          Class.  As to any  matter  that  does not  affect  the  interest  of a
          particular  Bond  Portfolio  Class,  only the holders of shares of the
          affected Bond Portfolio Class shall be entitled to vote.

     SECOND:  (a) The total  number of shares of capital  stock of the  Seligman
Capital  Portfolio Class of the  Corporation  (the "Capital  Portfolio  Series")
which the  Corporation has authority to issue is 80,000,000  shares,  which were
previously  classified by the Board of Directors of the Corporation as one class
of the Capital Portfolio Series.

     (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 Common Stock of the Capital
Portfolio 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 stock which the  Capital  Portfolio
     Series  has  authority  to issue  is  80,000,000  shares  of  common  stock
     ("Shares")  of the par value of $.001 each having an aggregate par value of
     $80,000.  The Common Stock of the Capital  Portfolio  Series shall have two
     subclasses of shares,  which shall be  designated  Class 1 Common Stock and
     Class 2 Common  Stock.  The number of  authorized  shares of Class 1 Common
     Stock and of Class 2 Common  Stock of the Capital  Portfolio  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-half of the authorized
     but unissued  shares of Common Stock of both  subclasses;  provided that at
     all times the aggregate authorized,  issued and outstanding shares of Class
     1 and Class 2 Common Stock of the Capital Portfolio Series shall not exceed
     the  authorized  number of shares of Common Stock of the Capital  Portfolio
     Series  (i.e.,  80,000,000  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.
     Each  subclass of Common  Stock of the Capital  Portfolio  Series  shall be
     referred  to  herein  individually  as  a  "Capital  Portfolio  Class"  and
     collectively, together with any further subclass or subclasses from time to
     time established, as the "Capital Portfolio Classes".

          (2) Each Capital  Portfolio Class shall represent the same interest in
     the Corporation and have identical voting, dividend, liquidation, and other
     rights; provided, however, that notwithstanding anything in the Articles of
     Amendment and Restatement of the Corporation to the contrary:

               (A) Expenses  related  solely to a particular  Capital  Portfolio
          Class (including,  without limitation,  shareholder servicing expenses
          under a Rule 12b-1 plan,  agreement  or other  arrangement,  which may
          differ between the Capital  Portfolio  Classes) shall be borne by that
          Capital  Portfolio 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
          Capital Portfolio Class.

               (B) As to any matter  with  respect  to which a separate  vote of
          either Capital  Portfolio 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  (A)  above),  such  requirement  as to a
          separate  vote by the Capital  Portfolio  Class shall apply in lieu of
          single  Capital  Portfolio  Class  voting,  and, if  permitted  by the
          Investment Company Act or any rules,  regulations or orders thereunder
          and the  Maryland  General  Corporation  Law,  the  Capital  Portfolio
          Classes shall vote


                                       2
<PAGE>


          together as a single Capital  Portfolio  Class on any such matter that
          shall have the same effect on each such Capital Portfolio Class. As to
          any matter that does not affect the interest of a  particular  Capital
          Portfolio  Class,  only the holders of shares of the affected  Capital
          Portfolio Class shall be entitled to vote.

     THIRD: (a) The total number of shares of capital stock of the Seligman Cash
Management  Portfolio Class of the Corporation (the "Cash  Management  Portfolio
Series") which the  Corporation  has authority to issue is  100,000,000  shares,
which were previously classified by the Board of Directors of the Corporation as
one class of the Cash Management Portfolio Series.

     (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 Common  Stock of the Cash
Management Portfolio 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 stock  which the Cash  Management
     Portfolio  Series has  authority to issue is  100,000,000  shares of common
     stock  ("Shares")  of the par value of $.001 each having an  aggregate  par
     value of $100,000. The Common Stock of the Cash Management Portfolio Series
     shall have two  subclasses  of shares,  which shall be  designated  Class 1
     Common Stock and Class 2 Common Stock.  The number of authorized  shares of
     Class 1 Common  Stock  and of Class 2 Common  Stock of the Cash  Management
     Portfolio  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-half of
     the  authorized  but unissued  shares of Common  Stock of both  subclasses;
     provided that at all times the aggregate authorized, issued and outstanding
     shares of Class 1 and Class 2 Common Stock of the Cash Management Portfolio
     Series shall not exceed the authorized  number of shares of Common Stock of
     the Cash Management  Portfolio Series (i.e.,  100,000,000  shares of Common
     Stock  until  changed  by  further  action  of the  Board of  Directors  in
     accordance with Section 2-208.1 of the Maryland General Corporation Law, 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. Each subclass of Common Stock
     of the Cash  Management  Portfolio  Series  shall  be  referred  to  herein
     individually  as a "Cash  Management  Portfolio  Class"  and  collectively,
     together  with  any  further  subclass  or  subclasses  from  time  to time
     established, as the "Cash Management Portfolio Classes".

          (2) Each Cash  Management  Portfolio  Class shall  represent  the same
     interest  in  the   Corporation  and  have  identical   voting,   dividend,
     liquidation,  and other rights;  provided,  however,  that  notwithstanding
     anything in the Articles of Amendment and Restatement of the Corporation to
     the contrary:

               (A)  Expenses  related  solely to a  particular  Cash  Management
          Portfolio Class (including, without limitation,  shareholder servicing
          expenses  under a Rule 12b-1  plan,  agreement  or other  arrangement,
          which may differ between the Cash Management  Portfolio Classes) shall
          be  borne  by that  Cash  Management  Portfolio  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 Cash  Management  Portfolio
          Class.

               (B) As to any matter  with  respect  to which a separate  vote of
          either Cash  Management  Portfolio 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 (A) above), such requirement as
          to a separate vote by the Cash Management  Portfolio Class shall apply
          in lieu of single Cash  Management  Portfolio  Class  voting,  and, if
          permitted by the Investment  Company Act or any rules,  regulations or
          orders  thereunder and the Maryland General  Corporation Law, the Cash
          Management  Portfolio  Classes  shall vote  together  as a single Cash
          Management Portfolio Class on any such matter that shall have the same
          effect on each such Cash


                                       3
<PAGE>


          Management  Portfolio Class. As to any matter that does not affect the
          interest of a particular Cash  Management  Portfolio  Class,  only the
          holders of shares of the  affected  Cash  Management  Portfolio  Class
          shall be entitled to vote.

     FOURTH:  (a) The total  number of shares of capital  stock of the  Seligman
Common Stock  Portfolio  Class of the  Corporation  (the "Common Stock Portfolio
Series") which the  Corporation  has authority to issue is  100,000,000  shares,
which were previously classified by the Board of Directors of the Corporation as
one class of the Common Stock Portfolio Series.

     (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 Common Stock of the Common
Stock  Portfolio  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 stock  which  the  Common  Stock
     Portfolio  Series has  authority to issue is  100,000,000  shares of common
     stock  ("Shares")  of the par value of $.001 each having an  aggregate  par
     value of $100,000.  The Common Stock of the Common Stock  Portfolio  Series
     shall have two  subclasses  of shares,  which shall be  designated  Class 1
     Common Stock and Class 2 Common Stock.  The number of authorized  shares of
     Class 1  Common  Stock  and of Class 2 Common  Stock  of the  Common  Stock
     Portfolio  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-half of
     the  authorized  but unissued  shares of Common  Stock of both  subclasses;
     provided that at all times the aggregate authorized, issued and outstanding
     shares of Class 1 and Class 2 Common  Stock of the Common  Stock  Portfolio
     Series shall not exceed the authorized  number of shares of Common Stock of
     the Common Stock Portfolio Series (i.e., 100,000,000 shares of Common Stock
     until  changed by further  action of the Board of Directors  in  accordance
     with  Section  2-208.1 of the  Maryland  General  Corporation  Law,  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. Each subclass of Common Stock of the Common
     Stock  Portfolio  Series  shall be  referred  to herein  individually  as a
     "Common Stock Portfolio Class" and collectively,  together with any further
     subclass or subclasses from time to time established,  as the "Common Stock
     Portfolio Classes".

          (2)  Each  Common  Stock  Portfolio  Class  shall  represent  the same
     interest  in  the   Corporation  and  have  identical   voting,   dividend,
     liquidation,  and other rights;  provided,  however,  that  notwithstanding
     anything in the Articles of Amendment and Restatement of the Corporation to
     the contrary:

               (A)  Expenses  related  solely  to  a  particular   Common  Stock
          Portfolio Class (including, without limitation,  shareholder servicing
          expenses  under a Rule 12b-1  plan,  agreement  or other  arrangement,
          which may differ between the Common Stock Portfolio  Classes) shall be
          borne by that Common Stock Portfolio 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 Common Stock Portfolio Class.

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

          Portfolio  Class,  only the holders of shares of the  affected  Common
          Stock Portfolio Class shall be entitled to vote.

     FIFTH:  (a) The total  number of shares of  capital  stock of the  Seligman
Communications   and  Information   Portfolio  Class  of  the  Corporation  (the
"Communications  and  Information  Portfolio  Series") which the Corporation has
authority to issue is 100,000,000  shares,  which were previously  classified by
the Board of Directors of the Corporation as one class of the Communications and
Information Portfolio Series.

     (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  Common  Stock  of  the
Communications and Information  Portfolio 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 stock which the  Communications  and
     Information  Portfolio Series has authority to issue is 100,000,000  shares
     of  common  stock  ("Shares")  of the par  value of $.001  each  having  an
     aggregate par value of $100,000. The Common Stock of the Communications and
     Information  Portfolio  Series shall have two  subclasses of shares,  which
     shall be  designated  Class 1 Common  Stock and Class 2 Common  Stock.  The
     number of  authorized  shares of Class 1 Common Stock and of Class 2 Common
     Stock of the  Communications  and Information  Portfolio  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-half  of the  authorized  but
     unissued  shares of Common Stock of both  subclasses;  provided that at all
     times the aggregate  authorized,  issued and outstanding  shares of Class 1
     and Class 2 Common Stock of the  Communications  and Information  Portfolio
     Series shall not exceed the authorized  number of shares of Common Stock of
     the  Communications  and Information  Portfolio  Series (i.e.,  100,000,000
     shares of Common  Stock  until  changed by  further  action of the Board of
     Directors  in  accordance  with  Section  2-208.1 of the  Maryland  General
     Corporation Law, 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.  Each  subclass of
     Common Stock of the Communications  and Information  Portfolio Series shall
     be referred to herein  individually  as a  "Communications  and Information
     Portfolio  Class" and  collectively,  together with any further subclass or
     subclasses  from  time  to time  established,  as the  "Communications  and
     Information Portfolio Classes".

          (2)  Each   Communications  and  Information   Portfolio  Class  shall
     represent the same interest in the Corporation  and have identical  voting,
     dividend,   liquidation,   and  other  rights;   provided,   however,  that
     notwithstanding  anything in the Articles of Amendment and  Restatement  of
     the Corporation to the contrary:

               (A) Expenses  related solely to a particular  Communications  and
          Information   Portfolio   Class   (including,    without   limitation,
          shareholder  servicing expenses under a Rule 12b-1 plan,  agreement or
          other  arrangement,  which may differ between the  Communications  and
          Information  Portfolio Classes) shall be borne by that  Communications
          and Information  Portfolio 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 Communications and Information Portfolio Class.

               (B) As to any matter  with  respect  to which a separate  vote of
          either  Communications and Information  Portfolio 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  (A)  above),   such
          requirement  as  to  a  separate  vote  by  the   Communications   and
          Information   Portfolio   Class   shall   apply  in  lieu  of   single
          Communications  and  Information   Portfolio  Class  voting,  and,  if
          permitted by the Investment  Company Act or any rules,  regulations or
          orders  thereunder  and the  Maryland  General  Corporation  Law,  the
          Communications  and Information  Portfolio Classes shall vote together
          as a single Communications and Information


                                       5
<PAGE>


          Portfolio  Class on any such matter that shall have the same effect on
          each such  Communications  and Information  Portfolio Class. As to any
          matter   that  does  not  affect   the   interest   of  a   particular
          Communications  and Information  Portfolio Class,  only the holders of
          shares of the affected  Communications and Information Portfolio Class
          shall be entitled to vote.

which the Corporation has authority to issue is 100,000,000  shares,  which were
previously  classified by the Board of Directors of the Corporation as one class
of the Frontier Portfolio Series.

     (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 Common Stock of the Frontier
Portfolio Series into the following subclasses, has provided for the issuance of

          (1) The total number of shares of stock which the  Frontier  Portfolio
     Series  has  authority  to issue is  100,000,000  shares  of  common  stock
     ("Shares")  of the par value of $.001 each having an aggregate par value of
     $100,000.  The Common Stock of the Frontier Portfolio Series shall have two
     subclasses of shares,  which shall be  designated  Class 1 Common Stock and
     Class 2 Common  Stock.  The number of  authorized  shares of Class 1 Common
     Stock and of Class 2 Common  Stock of the Frontier  Portfolio  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-half of the authorized
     but unissued  shares of Common Stock of both  subclasses;  provided that at
     all times the aggregate authorized,  issued and outstanding shares of Class
     1 and  Class 2 Common  Stock of the  Frontier  Portfolio  Series  shall not
     exceed  the  authorized  number of shares of Common  Stock of the  Frontier
     Portfolio Series (i.e., 100,000,000 shares of Common Stock until changed by
     further action of the Board of Directors in accordance with Section 2-208.1
     of the Maryland General Corporation Law, 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.
     Each  subclass of Common  Stock of the Frontier  Portfolio  Series shall be
     referred  to  herein  individually  as a  "Frontier  Portfolio  Class"  and
     collectively, together with any further subclass or subclasses from time to
     time established, as the "Frontier Portfolio Classes".

          (2) Each Frontier Portfolio Class shall represent the same interest in
     the Corporation and have identical voting, dividend, liquidation, and other
     rights; provided, however, that notwithstanding anything in the Articles of
     Amendment and Restatement of the Corporation to the contrary:

               (A) Expenses  related solely to a particular  Frontier  Portfolio
          Class (including,  without limitation,  shareholder servicing expenses
          under a Rule 12b-1 plan,  agreement  or other  arrangement,  which may
          differ between the Frontier  Portfolio Classes) shall be borne by that
          Frontier Portfolio 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
          Frontier Portfolio Class.

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


                                       6
<PAGE>


          interest of a particular Frontier Portfolio Class, only the holders of
          shares of the affected  Frontier  Portfolio Class shall be entitled to
          vote.

Income Portfolio Class of the Corporation (the "Income Portfolio  Series") which
the  Corporation  has  authority  to  issue is  80,000,000  shares,  which  were
previously  classified by the Board of Directors of the Corporation as one class
of the Income Portfolio Series.

     (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 Common Stock of the Income
Portfolio Series into the following subclasses, has provided for the issuance of

     $80,000.  The Common  Stock of the Income  Portfolio  Series shall have two
     subclasses of shares,  which shall be  designated  Class 1 Common Stock and
     Class 2 Common  Stock.  The number of  authorized  shares of Class 1 Common
     Stock and of Class 2 Common Stock of the Income Portfolio 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-half  of the  authorized  but
     unissued  shares of Common Stock of both  subclasses;  provided that at all
     times the aggregate  authorized,  issued and outstanding  shares of Class 1
     and Class 2 Common  Stock of the Income  Portfolio  Series shall not exceed
     the  authorized  number of shares of Common  Stock of the Income  Portfolio
     Series  (i.e.,  80,000,000  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.
     Each  subclass  of Common  Stock of the Income  Portfolio  Series  shall be
     referred  to  herein   individually  as  a  "Income  Portfolio  Class"  and
     collectively, together with any further subclass or subclasses from time to

          (2) Each Income  Portfolio  Class shall represent the same interest in
     the Corporation and have identical voting, dividend, liquidation, and other
     rights; provided, however, that notwithstanding anything in the Articles of
     Amendment and Restatement of the Corporation to the contrary:

               (A)  Expenses  related  solely to a particular  Income  Portfolio
          Class (including,  without limitation,  shareholder servicing expenses
          under a Rule 12b-1 plan,  agreement  or other  arrangement,  which may
          differ  between the Income  Portfolio  Classes) shall be borne by that
          Income  Portfolio 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
          Income Portfolio Class.

               (B) As to any matter  with  respect  to which a separate  vote of
          either Income  Portfolio  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  (A)  above),  such  requirement  as to a
          separate  vote by the Income  Portfolio  Class  shall apply in lieu of
          single  Income  Portfolio  Class  voting,  and,  if  permitted  by the
          Investment Company Act or any rules,  regulations or orders thereunder
          and the Maryland General Corporation Law, the Income Portfolio Classes
          shall vote  together as a single  Income  Portfolio  Class on any such
          matter that shall have the same  effect on each such Income  Portfolio
          Class.  As to any  matter  that  does not  affect  the  interest  of a
          particular  Income Portfolio Class,  only the holders of shares of the
          affected Income Portfolio Class shall be entitled to vote.

     stock  ("Shares")  of the par value of $.001 each having an  aggregate  par
     value of $80,000.  The Common Stock of the  International  Growth Portfolio

     shall have two  subclasses  of shares,  which shall be  designated  Class 1
     Common Stock and Class 2 Common Stock.  The number of authorized  shares of
     Class 1 Common  Stock and of Class 2 Common  Stock of the  High-Yield  Bond
     Portfolio  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-half of
     the  authorized  but unissued  shares of Common  Stock of both  subclasses;
     provided that at all times the aggregate authorized, issued and outstanding

          (2) Each  High-Yield  Bond  Portfolio  Class shall  represent the same
     interest  in  the   Corporation  and  have  identical   voting,   dividend,
     liquidation,  and other rights;  provided,  however,  that  notwithstanding
     anything in the Articles of Amendment and Restatement of the Corporation to
     the contrary:

               (A)  Expenses  related  solely to a  particular  High-Yield  Bond

          which may differ between the High-Yield Bond Portfolio  Classes) shall
          be  borne  by that  High-Yield  Bond  Portfolio  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  High-Yield  Bond  Portfolio
          Class.

          either  High-Yield  Bond Portfolio 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 (A) above), such requirement as
          to a separate vote by the High-Yield  Bond Portfolio Class shall apply
          in lieu of single  High-Yield  Bond  Portfolio  Class voting,  and, if
          permitted by the Investment  Company Act or any rules,  regulations or
          orders  thereunder  and the  Maryland  General  Corporation  Law,  the
          High-Yield  Bond  Portfolio  Classes  shall vote  together as a single
          High-Yield Bond Portfolio Class on any such matter that shall have the
          same effect on each such  High-Yield  Bond Portfolio  Class. As to any
          matter that does not affect the  interest of a  particular  High-Yield
          Bond  Portfolio  Class,  only the  holders  of shares of the  affected
          High-Yield Bond Portfolio Class shall be entitled to vote.

to issue is 20,000,000 shares, which were previously  classified by the Board of
Directors of the Corporation as one class of the Global Growth Portfolio Series.

     (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 Common Stock of the Global
Growth  Portfolio  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 stock  which  the  Global  Growth
     Portfolio  Series has  authority  to issue is  20,000,000  shares of common
     stock  ("Shares")  of the par value of $.001 each having an  aggregate  par
     value of $20,000.  The Common Stock of the Global Growth  Portfolio  Series
     shall have two  subclasses  of shares,  which shall be  designated  Class 1
     Common Stock and Class 2 Common Stock.  The number of authorized  shares of
     Class 1  Common  Stock  and of Class 2 Common  Stock of the  Global  Growth
     Portfolio  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-half of
     the  authorized  but unissued  shares of Common  Stock of both  subclasses;
     provided that at all times the aggregate authorized, issued and outstanding
     shares of Class 1 and Class 2 Common Stock of the Global  Growth  Portfolio
     Series shall not exceed the authorized  number of shares of Common Stock of
     the Global Growth Portfolio Series (i.e., 20,000,000 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. Each subclass of Common Stock of the Global
     Growth  Portfolio  Series  shall be  referred to herein  individually  as a
     "Global Growth Portfolio Class" and collectively, together with any further
     subclass or subclasses from time to time established, as the "Global Growth
     Portfolio Classes".

          (2) Each  Global  Growth  Portfolio  Class  shall  represent  the same
     interest  in  the   Corporation  and  have  identical   voting,   dividend,
     liquidation,  and other rights;  provided,  however,  that  notwithstanding
     anything in the Articles of Amendment and Restatement of the Corporation to
     the contrary:

               (A)  Expenses  related  solely  to  a  particular  Global  Growth
          Portfolio Class (including, without limitation,  shareholder servicing
          expenses  under a Rule 12b-1  plan,  agreement  or other  arrangement,
          which may differ between the Global Growth Portfolio Classes) shall be
          borne by that Global Growth Portfolio 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 Portfolio Class.

               (B) As to any matter  with  respect  to which a separate  vote of
          either Global  Growth  Portfolio  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 (A) above), such requirement as
          to a separate vote by the Global Growth Portfolio Class shall apply in
          lieu of single Global Growth Portfolio 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
          Portfolio  Classes  shall  vote  together  as a single  Global  Growth
          Portfolio  Class on any such matter that shall have the same effect on
          each such Global Growth  Portfolio  Class.  As to any matter that does
          not affect the interest of a particular Global Growth Portfolio Class,
          only the holders of shares of the  affected  Global  Growth  Portfolio
          Class shall be entitled to vote.

     ELEVENTH:  (a) The total number of shares of capital  stock of the Seligman
Global Smaller Companies Portfolio Class of the Corporation (the "Global Smaller
Companies  Portfolio  Series") which the  Corporation  has authority to issue is
80,000,000 shares, which were previously classified by the Board of Directors of
the Corporation as one class of the Global Smaller Companies Portfolio Series.

     (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 Common Stock of the Global
Smaller Companies Portfolio 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 stock  which the  Global  Smaller
     Companies  Portfolio Series has authority to issue is 80,000,000  shares of
     common stock  ("Shares") of the par value of $.001 each having an aggregate
     par value of  $80,000.  The Common  Stock of the Global  Smaller  Companies
     Portfolio  Series  shall  have two  subclasses  of shares,  which  shall be
     designated  Class 1 Common  Stock and Class 2 Common  Stock.  The number of
     authorized  shares of Class 1 Common  Stock and of Class 2 Common  Stock of
     the Global Smaller Companies Portfolio 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-half of the  authorized  but unissued  shares of
     Common Stock of both  subclasses;  provided that at all times the aggregate
     authorized,  issued  and  outstanding  shares of Class 1 and Class 2 Common
     Stock of the Global Smaller Companies Portfolio Series shall not exceed the
     authorized number of shares of Common Stock of the Global Smaller Companies
     Portfolio Series (i.e.,  80,000,000 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.
     Each  subclass of Common Stock of the Global  Smaller  Companies  Portfolio
     Series  shall be  referred  to herein  individually  as a  "Global  Smaller
     Companies  Portfolio  Class" and  collectively,  together  with any further
     subclass  or  subclasses  from  time to time  established,  as the  "Global
     Smaller Companies Portfolio Classes".

          (2) Each Global Smaller Companies  Portfolio Class shall represent the
     same  interest in the  Corporation  and have  identical  voting,  dividend,
     liquidation,  and other rights;  provided,  however,  that  notwithstanding
     anything in the Articles of Amendment and Restatement of the Corporation to
     the contrary:

               (A)  Expenses  related  solely  to a  particular  Global  Smaller
          Companies Portfolio Class (including, without limitation,  shareholder
          servicing  expenses  under  a Rule  12b-1  plan,  agreement  or  other
          arrangement,  which may differ  between the Global  Smaller  Companies
          Portfolio  Classes)  shall be borne by that Global  Smaller  Companies
          Portfolio  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 Portfolio Class.

               (B) As to any matter  with  respect  to which a separate  vote of
          either Global  Smaller  Companies  Portfolio  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  (A)  above),   such
          requirement  as to a  separate  vote by the Global  Smaller  Companies
          Portfolio Class shall apply in lieu of single Global Smaller Companies
          Portfolio  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  Portfolio
          Classes  shall vote  together  as a single  Global  Smaller  Companies
          Portfolio  Class on any such matter that shall have the same effect on
          each such Global Smaller  Companies  Portfolio Class. As to any matter
          that does not affect  the  interest  of a  particular  Global  Smaller
          Companies  Portfolio Class, only the holders of shares of the affected
          Global Smaller Companies Portfolio Class shall be entitled to vote.

     TWELFTH:  (a) The total  number of shares of capital  stock of the Seligman
Global  Technology  Portfolio Class of the Corporation  (the "Global  Technology
Portfolio  Series") which the  Corporation  has authority to issue is 20,000,000
shares,  which  were  previously  classified  by the Board of  Directors  of the

     (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 Common Stock of the Global
Technology Portfolio 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 stock  which the Global  Technology
     Portfolio  Series has  authority  to issue is  20,000,000  shares of common
     stock  ("Shares")  of the par value of $.001 each having an  aggregate  par
     value of  $20,000.  The  Common  Stock of the Global  Technology  Portfolio
     Series shall have two subclasses of shares, which shall be designated Class
     1 Common Stock and Class 2 Common Stock. The number of authorized shares of
     Class 1 Common Stock and of Class 2 Common  Stock of the Global  Technology
     Portfolio  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-half of
     the  authorized  but unissued  shares of Common  Stock of both  subclasses;
     provided that at all times the aggregate authorized, issued and outstanding
     shares  of  Class 1 and  Class 2  Common  Stock  of the  Global  Technology
     Portfolio Series shall not exceed the authorized number of shares of Common
     Stock of the Global Technology Portfolio Series (i.e., 20,000,000 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. Each subclass of Common Stock
     of the Global  Technology  Portfolio  Series  shall be  referred  to herein
     individually as a "Global  Technology  Portfolio  Class" and  collectively,
     together  with  any  further  subclass  or  subclasses  from  time  to time
     established, as the "Global Technology Portfolio Classes".

          (2) Each Global  Technology  Portfolio  Class shall represent the same
     interest  in  the   Corporation  and  have  identical   voting,   dividend,
     liquidation,  and other rights;  provided,  however,  that  notwithstanding
     anything in the Articles of Amendment and Restatement of the Corporation to
     the contrary:

               (A) Expenses  related  solely to a particular  Global  Technology
          Portfolio Class (including, without limitation,  shareholder servicing
          expenses  under a Rule 12b-1  plan,  agreement  or other  arrangement,
          which may differ  between  the Global  Technology  Portfolio  Classes)
          shall be borne by that Global Technology  Portfolio 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 Technology  Portfolio
          Class.

               (B) As to any matter  with  respect  to which a separate  vote of
          either Global Technology Portfolio 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 (A) above), such requirement as
          to a separate  vote by the Global  Technology  Portfolio  Class  shall
          apply in lieu of single Global Technology Portfolio 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  Portfolio  Classes shall vote together as a single
          Global  Technology  Portfolio Class on any such matter that shall have
          the same effect on each such Global Technology  Portfolio Class. As to
          any matter that does not affect the  interest of a  particular  Global
          Technology Portfolio Class, only the holders of shares of the affected
          Global Technology Portfolio Class shall be entitled to vote.

Large-Cap  Growth  Portfolio  Class of the Corporation  (the  "Large-Cap  Growth
Portfolio  Series") which the  Corporation  has authority to issue is 20,000,000
shares,  which  were  previously  classified  by the Board of  Directors  of the
Corporation as one class of the Large-Cap Growth Portfolio Series.

     stock  ("Shares")  of the par value of $.001 each having an  aggregate  par
     value of $20,000. The Common Stock of the Large-Cap Growth Portfolio Series
     shall have two  subclasses  of shares,  which shall be  designated  Class 1
     Common Stock and Class 2 Common Stock.  The number of authorized  shares of
     Class 1 Common  Stock and of Class 2 Common Stock of the  Large-Cap  Growth
     Portfolio  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-half of
     the  authorized  but unissued  shares of Common  Stock of both  subclasses;
     provided that at all times the aggregate authorized, issued and outstanding
     shares  of  Class 1 and  Class  2  Common  Stock  of the  Large-Cap  Growth
     Portfolio Series shall not exceed the authorized number of shares of Common
     Stock of the Large-Cap Growth Portfolio Series (i.e.,  20,000,000 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

     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. Each subclass of Common Stock
     of the  Large-Cap  Growth  Portfolio  Series  shall be  referred  to herein
     individually  as a "Large-Cap  Growth  Portfolio  Class" and  collectively,
     together  with  any  further  subclass  or  subclasses  from  time  to time
     established, as the "Large-Cap Growth Portfolio Classes".

          (2) Each Large-Cap  Growth  Portfolio  Class shall  represent the same
     interest  in  the   Corporation  and  have  identical   voting,   dividend,
     liquidation,  and other rights;  provided,  however,  that  notwithstanding
     anything in the Articles of Amendment and Restatement of the Corporation to
     the contrary:

               (A)  Expenses  related  solely to a particular  Large-Cap  Growth
          Portfolio Class (including, without limitation,  shareholder servicing
          expenses  under a Rule 12b-1  plan,  agreement  or other  arrangement,
          which may differ between the Large-Cap Growth Portfolio Classes) shall
          be  borne  by that  Large-Cap  Growth  Portfolio  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 Large-Cap  Growth  Portfolio
          Class.

               (B) As to any matter  with  respect  to which a separate  vote of
          either  Large-Cap Growth Portfolio 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 (A) above), such requirement as
          to a separate vote by the Large-Cap Growth Portfolio Class shall apply
          in lieu of single  Large-Cap  Growth  Portfolio Class voting,  and, if
          permitted by the Investment  Company Act or any rules,  regulations or
          orders  thereunder  and the  Maryland  General  Corporation  Law,  the
          Large-Cap  Growth  Portfolio  Classes  shall vote together as a single
          Large-Cap  Growth  Portfolio  Class on any such matter that shall have
          the same effect on each such Large-Cap  Growth  Portfolio Class. As to
          any matter that does not affect the interest of a particular Large-Cap
          Growth  Portfolio  Class,  only the holders of shares of the  affected
          Large-Cap Growth Portfolio Class shall be entitled to vote.

     FOURTEENTH  (a) The total number of shares of capital stock of the Seligman
Large-Cap  Value  Portfolio  Class  of the  Corporation  (the  "Large-Cap  Value

     stock  ("Shares")  of the par value of $.001 each having an  aggregate  par
     value of $20,000.  The Common Stock of the Large-Cap Value Portfolio Series
     shall have two  subclasses  of shares,  which shall be  designated  Class 1
     Common Stock and Class 2 Common Stock.  The number of authorized  shares of
     Class 1 Common  Stock and of Class 2 Common  Stock of the  Large-Cap  Value
     Portfolio  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-half of

     shares of Class 1 and Class 2 Common Stock of the Large-Cap Value Portfolio
     Series shall not exceed the authorized  number of shares of Common Stock of
     the Large-Cap Value  Portfolio  Series (i.e.,  20,000,000  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

     above would  result,  at any time,  in fractional  shares,  the  applicable

     nearest whole number of shares of such class. Each subclass of Common Stock
     of the  Large-Cap  Value  Portfolio  Series  shall be  referred  to  herein
     individually  as a  "Large-Cap  Value  Portfolio  Class" and  collectively,
     together  with  any  further  subclass  or  subclasses  from  time  to time
     established, as the "Large-Cap Value Portfolio Classes".

          (2) Each  Large-Cap  Value  Portfolio  Class shall  represent the same
     interest  in  the   Corporation  and  have  identical   voting,   dividend,
     liquidation,  and other rights;  provided,  however,  that  notwithstanding
     anything in the Articles of Amendment and Restatement of the Corporation to
     the contrary:

               (A)  Expenses  related  solely to a  particular  Large-Cap  Value
          Portfolio Class (including, without limitation,  shareholder servicing
          expenses  under a Rule 12b-1  plan,  agreement  or other  arrangement,
          which may differ between the Large-Cap Value Portfolio  Classes) shall
          be  borne  by that  Large-Cap  Value  Portfolio  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  Large-Cap  Value  Portfolio
          Class.

               (B) As to any matter  with  respect  to which a separate  vote of
          either  Large-Cap  Value Portfolio 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 (A) above), such requirement as
          to a separate vote by the Large-Cap  Value Portfolio Class shall apply
          in lieu of single  Large-Cap  Value  Portfolio  Class voting,  and, if
          permitted by the Investment  Company Act or any rules,  regulations or
          orders  thereunder  and the  Maryland  General  Corporation  Law,  the
          Large-Cap  Value  Portfolio  Classes  shall vote  together as a single
          Large-Cap Value Portfolio Class on any such matter that shall have the
          same effect on each such Large-Cap  Value  Portfolio  Class. As to any
          matter  that does not affect the  interest of a  particular  Large-Cap
          Value  Portfolio  Class,  only the  holders of shares of the  affected
          Large-Cap Value Portfolio Class shall be entitled to vote.

     FIFTEENTH:  (a) The total number of shares of capital stock of the Seligman
Small-Cap  Value  Portfolio  Class  of the  Corporation  (the  "Small-Cap  Value
Portfolio  Series") which the  Corporation  has authority to issue is 20,000,000
shares,  which  were  previously  classified  by the Board of  Directors  of the

Common  Stock  of the  Small-Cap  Value  Portfolio  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 stock  which the  Small-Cap  Value
     Portfolio  Series has  authority  to issue is  20,000,000  shares of common
     stock  ("Shares")  of the par value of $.001 each having an  aggregate  par
     value of $20,000.  The Common Stock of the Small-Cap Value Portfolio Series
     shall have two  subclasses  of shares,  which shall be  designated  Class 1
     Common Stock and Class 2 Common Stock.  The number of authorized  shares of
     Class 1 Common  Stock and of Class 2 Common  Stock of the  Small-Cap  Value
     Portfolio  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-half of
     the  authorized  but unissued  shares of Common  Stock of both  subclasses;
     provided that at all times the aggregate authorized, issued and outstanding
     shares of Class 1 and Class 2 Common Stock of the Small-Cap Value Portfolio
     Series shall not exceed the authorized  number of shares of Common Stock of
     the Small-Cap Value  Portfolio  Series (i.e.,  20,000,000  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. Each subclass of Common Stock
     of the  Small-Cap  Value  Portfolio  Series  shall be  referred  to  herein
     individually  as a  "Small-Cap  Value  Portfolio  Class" and  collectively,
     together  with  any  further  subclass  or  subclasses  from  time  to time
     established, as the "Small-Cap Value Portfolio Classes".

          (2) Each  Small-Cap  Value  Portfolio  Class shall  represent the same
     interest  in  the   Corporation  and  have  identical   voting,   dividend,
     liquidation,  and other rights;  provided,  however,  that  notwithstanding
     anything in the Articles of Amendment and Restatement of the Corporation to
     the contrary:

               (A)  Expenses  related  solely to a  particular  Small-Cap  Value
          Portfolio Class (including, without limitation,  shareholder servicing
          expenses  under a Rule 12b-1  plan,  agreement  or other  arrangement,
          which may differ between the Small-Cap Value Portfolio  Classes) shall
          be  borne  by that  Small-Cap  Value  Portfolio  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  Small-Cap  Value  Portfolio
          Class.

               (B) As to any matter  with  respect  to which a separate  vote of
          either  Small-Cap  Value Portfolio 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 (A) above), such requirement as
          to a separate vote by the Small-Cap  Value Portfolio Class shall apply
          in lieu of single  Small-Cap  Value  Portfolio  Class voting,  and, if
          permitted by the Investment  Company Act or any rules,  regulations or
          orders  thereunder  and the  Maryland  General  Corporation  Law,  the
          Small-Cap  Value  Portfolio  Classes  shall vote  together as a single
          Small-Cap Value Portfolio Class on any such matter that shall have the
          same effect on each such Small-Cap  Value  Portfolio  Class. As to any
          matter  that does not affect the  interest of a  particular  Small-Cap
          Value  Portfolio  Class,  only the  holders of shares of the  affected
          Small-Cap Value Portfolio Class shall be entitled to vote.

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

                DISTRIBUTION AND SHAREHOLDER SERVICING AGREEMENT


     DISTRIBUTION  AND SHAREHOLDER  SERVICING  AGREEMENT,  dated as of March 16,
2000, between SELIGMAN  PORTFOLIOS,  INC., a Maryland  corporation (the "Fund"),
and SELIGMAN ADVISORS, INC., a Delaware corporation ("Seligman Advisors").

     WHEREAS,  the Fund is registered under the Investment  Company Act of 1940,
as amended  ("1940  Act"),  as an open-end,  diversified  management  investment
company  and  has  established   several  separate  series  of  shares  (each  a
"Portfolio"), with each Portfolio having its own assets and investment policies;

     WHEREAS,  the Portfolios  propose to issue and sell their shares of capital
stock ("Shares") to separate  accounts of participating  insurance  companies to
fund  benefits  of  variable  annuity  contracts  and,  upon the  receipt  of an
exemptive order from the Securities and Exchange  Commission  ("SEC"),  variable
life insurance contracts; and

     WHEREAS,   the  Fund  desires  to  retain  Seligman   Advisors  to  furnish
distribution  services  to each  Portfolio  of the Fund  listed  in  Schedule  A
attached hereto, and Seligman Advisors is willing to furnish such services.

     NOW THEREFORE,  in consideration of the mutual  agreements herein made, the
parties hereto agree as follows:

1.   Exclusive Distributor.  The Fund hereby agrees that Seligman Advisors shall
     be for the period of this Agreement exclusive agent for distribution within
     the United States and its territories,  and Seligman Advisors agrees to use
     its best efforts during such period to effect such  distribution  of Shares
     of the Portfolios. The Fund understands that Seligman Advisors also acts as
     agent  for  distribution  of the  shares  of  capital  stock or  beneficial
     interest of other  open-end  investment  companies  which have entered into
     management  agreements  with  J.  & W.  Seligman  & Co.  Incorporated  (the
     "Manager").

2.   Sales of Shares. Seligman Advisors is authorized, as agent for the Fund and
     not as principal, to sell Shares of the Portfolios to (a) separate accounts
     of  participating  insurance  companies in  accordance  with  participation
     agreements between the Fund and participating  insurance  companies to fund
     variable  annuity  contracts  and, upon receipt by the Fund of an exemptive
     order from the SEC,  variable life insurance  contracts;  or (b) pension or
     retirement  plans intended to qualify under  Sections  401(a) and 501(c) of
     the Internal Revenue Code of 1986, as amended;  provided,  however, that no
     sales of Shares shall be  confirmed by Seligman  Advisors at any time when,
     according  to advice  received  by  Seligman  Advisors  from the Fund,  the
     officers of the Fund have for any reason  sufficient to them temporarily or
     permanently  suspended or discontinued the sale and issuance of the Shares.
     Each sale of Shares of a Portfolio shall be effected by Seligman


<PAGE>


     Advisors only at net asset value,  determined in accordance with the Fund's
     then current  prospectus  relating to such Shares.  Seligman Advisors shall
     comply with all applicable laws, rules and regulations  including,  without
     limiting the generality of the foregoing,  all rules or regulations made or
     adopted  pursuant to Section 22 of the Investment  Company Act of 1940 (the
     "1940 Act") by the  Securities  and Exchange  Commission or any  securities
     association registered under the Securities Exchange Act of 1934.

     The Fund agrees,  as long as its Shares may legally be issued,  to fill all
     orders confirmed by Seligman  Advisors in accordance with the provisions of
     this Agreement.

3.   Repurchase Agent.  Seligman  Advisors is authorized,  as agent for the Fund
     and not as  principal,  to  accept  offers  for  resale  to the Fund and to
     repurchase  on behalf of the Fund  Shares  of the  Portfolios  at net asset
     values  determined  by  the  Fund  in  conformity  with  its  then  current
     prospectus relating to such Shares.

4.   Compensation.  In accordance with the terms of the Portfolios'  Shareholder
     Servicing  and  Distribution  Plan (the  "Plan"),  each  Portfolio may make
     payments  from time to time to  Seligman  Advisors in  accordance  with the
     terms  and  limitations  of,  and for the  purposes  set forth in the Plan.
     Seligman Advisors may use such payments,  in its discretion,  to compensate
     participating   insurance   companies   or  other   entities   who  provide
     distribution assistance and/or shareholder services to the extent permitted
     by  the  Plan.  Seligman  Advisors  will  not  be  entitled  to  any  other
     compensation under this Agreement.

5.   Expenses.  Except as provided in this Agreement and in accordance  with the
     Plan,  Seligman  Advisors shall pay all its own costs and expenses incurred
     in connection with the sale of Shares. Seligman Advisors also agrees to pay
     all fees and related  expenses  connected with its own  qualification  as a
     broker or dealer under Federal or State laws.

     The Fund  agrees  to pay all  fees  and  expenses  in  connection  with the
     preparation,  printing  and  distribution  of  copies  of  any  prospectus,
     statement  of  additional  information,  report or other  communication  to
     shareholders, or any other material used by Seligman Advisors in connection
     with offering Shares of the Portfolios for sale, all expenses in connection
     with the  registration of Shares of the Portfolios under the Securities Act
     of 1933 (the "Act"), all fees and related expenses which may be incurred in
     connection with the  qualification  of Shares of the Portfolios for sale in
     such  States (as well as the  District of  Columbia,  Puerto Rico and other
     territories)  as  Seligman  Advisors  may  designate,  and all  expenses in
     connection  with  maintaining  facilities  for the  issue and  transfer  of
     Shares, of


                                       2
<PAGE>


     supplying  information,  prices  and  other  data  to  be  furnished  by it
     hereunder,  and through  [Seligman Data Corp.],  of all data processing and
     related services related to the share  distribution  activity  contemplated
     hereby.

     The Fund agrees to execute such  documents and to furnish such  information
     as may be reasonably  necessary,  in the discretion of the Directors of the
     Fund, in connection with the  qualification of Shares of the Portfolios for
     sale in such States (as well as the District of  Columbia,  Puerto Rico and
     other  territories)  as Seligman  Advisors  may  designate,  and to pay all
     expenses  of  qualifying  the Fund as a dealer or broker  under the laws of
     such States as may be designated by Seligman Advisors,  if deemed necessary
     or advisable by the Fund.

     It is  understood  and agreed that any payments  made to Seligman  Advisors
     pursuant  to the Plan  may be used to  defray  some or all of the  expenses
     incurred by Seligman Advisors pursuant to this Agreement.

6.   Prospectus and Other  Information.  The Fund represents and warrants to and
     agrees with Seligman Advisors that:

     (a)  A  registration  statement,  including  prospectuses  relating  to the
          Shares of the Portfolios, has been filed by the Fund under the Act and
          has become effective.  Such registration  statement,  as now in effect
          and as  from  time to time  hereafter  amended,  and  also  any  other
          registration  statement  relating to the Shares  which may be filed by
          the Fund  under  the Act  which  shall  become  effective,  is  herein
          referred  to as the  "Registration  Statement",  and any  prospectuses
          filed  by the  Fund as a part of the  Registration  Statement,  as the
          "Prospectuses".

     (b)  At all  times  during  the  term of this  Agreement,  except  when the
          officers  of the Fund  have  suspended  or  discontinued  the sale and
          issuance  of Shares of the  Portfolios  as  contemplated  by Section 2
          hereof,  the Registration  Statement and Prospectuses  will conform in
          all  respects  to the  requirements  of the  Act  and  the  rules  and
          regulations of the Securities and Exchange Commission,  and neither of
          such documents will include any untrue statement of a material fact or
          omit to state any  material  fact  required  to be stated  therein  or
          necessary to make the statement  therein not  misleading,  except that
          the foregoing  does not apply to any statements or omissions in either
          of such documents based upon written information furnished to the Fund
          by Seligman Advisors specifically for use therein.

     The Fund agrees to prepare and  furnish to Seligman  Advisors  from time to
     time a copy of its  Prospectuses,  and authorizes  Seligman Advisors to use
     such


                                       3
<PAGE>


     Prospectuses, in the form furnished to Seligman Advisors from time to time,
     in connection with the sale of the Portfolios' Shares. The Fund also agrees
     to furnish Seligman  Advisors from time to time, for use in connection with
     the sale of such Shares,  such  information  with respect to the Portfolios
     and their Shares as Seligman Advisors may reasonably request.

7.   Reports. Seligman Advisors will prepare and furnish to the Directors of the
     Fund at least quarterly a written report complying with the requirements of
     Rule 12b-1 under the 1940 Act setting forth all amounts  expended under the
     Plan and the purposes for which such expenditures were made.

8.   Indemnification.

     (a)  The Fund will indemnify and hold harmless  Seligman  Advisors and each
          person,  if any, who controls  Seligman Advisors within the meaning of
          the Act against any losses,  claims,  damages or  liabilities to which
          Seligman Advisors or such controlling person may become subject, under
          the Act or  otherwise,  insofar  as such  losses,  claims,  damages or
          liabilities (or actions in respect  thereof) arise out of or are based
          upon any untrue  statement or alleged  untrue  statement of a material
          fact contained in the Fund's Registration  Statement or any Prospectus
          or any other  written  sales  material  prepared  by the Fund which is
          utilized by Seligman Advisors in connection with the sale of Shares or
          arise out of or are based upon the  omission  or alleged  omission  to
          state therein a material fact required to be stated therein or (in the
          case of the  Registration  Statement and any Prospectus)  necessary to
          make the  statements  therein not  misleading  or (in the case of such
          other sales  material)  necessary to make the  statements  therein not
          misleading  in the light of the  circumstances  under  which they were
          made; and will reimburse  Seligman  Advisors and each such controlling
          person for any legal or other expenses reasonably incurred by Seligman
          Advisors or such controlling  person in connection with  investigating
          or  defending  any such  loss,  claim,  damage,  liability  or action;
          provided,  however,  that the Fund will not be liable in any such case
          to the extent that any such loss,  claim,  damage or liability  arises
          out of or is  based  upon  any  untrue  statement  or  alleged  untrue
          statement or omission or alleged  omission  made in such  Registration
          Statement  or  Prospectus  in  conformity  with  written   information
          furnished  to the  Fund  by  Seligman  Advisors  specifically  for use
          therein;  and  provided,  further,  that  nothing  herein  shall be so
          construed as to protect Seligman Advisors against any liability to the
          Fund  or  its  security  holders  to  which  Seligman  Advisors  would
          otherwise  be subject by reason of willful  misfeasance,  bad faith or
          gross  negligence,  in the performance of its duties,  or by reason of


                                       4
<PAGE>


          the reckless  disregard by Seligman  Advisors of its  obligations  and
          duties  under this  Agreement.  This  indemnity  agreement  will be in
          addition to any liability which the Fund may otherwise have.

     (b)  Seligman  Advisors will indemnify and hold harmless the Fund,  each of
          its Directors  and officers and each person,  if any, who controls the
          Fund  within  the  meaning of the Act,  against  any  losses,  claims,
          damages or liabilities to which the Fund or any such Director, officer
          or controlling person may become subject,  under the Act or otherwise,
          insofar as such losses,  claims, damages or liabilities (or actions in
          respect  thereof) arise out of or are based upon any untrue  statement
          or alleged  untrue  statement  of a  material  fact  contained  in the
          Registration  Statement or any  Prospectus  or any sales  material not
          prepared by the Fund which is utilized in connection  with the sale of
          Shares or arise out of or are based upon the  omission  or the alleged
          omission  to state  therein  a  material  fact  required  to be stated
          therein or (in the case of the Registration  Statement and Prospectus)
          necessary to make the  statements  therein not  misleading  or (in the
          case of such other sales  material)  necessary to make the  statements
          therein not misleading in the light of the  circumstances  under which
          they were  made,  in the case of the  Registration  Statement  and any
          Prospectus  to the extent,  but only to the  extent,  that such untrue
          statement or alleged untrue  statement or omission or alleged omission
          was made in conformity with written information  furnished to the Fund
          by  Seligman  Advisors  specifically  for use  therein;  and  Seligman
          Advisors  will  reimburse  any  legal  or  other  expenses  reasonably
          incurred  by the Fund or any such  Director,  officer  or  controlling
          person in connection  with  investigating  or defending any such loss,
          claim,  damage,  liability or action. This indemnity agreement will be
          in addition to any  liability  which  Seligman  Advisors may otherwise
          have.

     (c)  Promptly after receipt by an  indemnified  party under this Section of
          notice of the commencement of any action, such indemnified party will,
          if a claim in respect  thereof is to be made against the  indemnifying
          party  under  this  Section,  notify  the  indemnifying  party  of the
          commencement  thereof;  but the omission so to notify the indemnifying
          party  will not  relieve  it from  liability  which it may have to any
          indemnified party otherwise than under this Section.  In case any such
          action is brought against any indemnified  party,  and it notifies the
          indemnifying party of the commencement thereof, the indemnifying party
          will be entitled to participate therein and, to the extent that it may
          wish, to assume the defense thereof, with counsel satisfactory to such
          indemnified  party,  and after notice from the  indemnifying  party to
          such indemnified  party of its


                                       5
<PAGE>


          election to assume the defense thereof,  the  indemnifying  party will
          not be liable to such  indemnified  party  under this  Section for any
          legal or other  expenses  subsequently  incurred  by such  indemnified
          party in connection  with the defense  thereof  other than  reasonable
          costs of investigation.

9.   Effective Date. This Agreement shall become effective upon its execution by
     an authorized officer of the respective  parties to this Agreement,  but in
     no event prior to shareholder approval of the Plan.

10.  Term of Agreement.  This Agreement  shall continue in effect until December
     31,  2001  and  through  December  31  of  each  year  thereafter  if  such
     continuance  is  approved  in the manner  required  by the 1940 Act and the
     rules thereunder and Seligman  Advisors shall not have notified the Fund in
     writing  at least 60 days  prior to the  anniversary  date of the  previous
     continuance that it does not desire such continuance. This Agreement may be
     terminated  with  respect to a Portfolio  at any time,  without  payment of
     penalty on 60 days' written notice to the other party by vote of a majority
     of the Directors of the Fund who are not interested  persons (as defined in
     the 1940 Act) of the Fund and have no direct or indirect financial interest
     in the operation of the Plan or any agreement  related thereto,  or by vote
     of a majority of the  outstanding  voting  securities of such Portfolio (as
     defined in the 1940 Act). This Agreement shall  automatically  terminate in
     the event of its assignment (as defined in the 1940 Act).

11.  Miscellaneous.  This  Agreement  shall  be  governed  by and  construed  in
     accordance  with the laws of the State of New York.  Anything herein to the
     contrary notwithstanding, this Agreement shall not be construed to require,
     or to  impose  any duty  upon,  either of the  parties  to do  anything  in
     violation of any applicable laws or regulations.

                              W I T N E S S E T H :


     WHEREAS,  the Fund is a registered open-end  management  investment company
under the Investment  Company Act of 1940, as amended (the "1940 Act"),  and has
filed a  currently  effective  registration  statement  to offer and sell of its
shares under the Securities Act of 1933, as amended (the "1933 Act"); and

     WHEREAS,  the Fund  desires to act as an  investment  vehicle for  separate
accounts  established for variable life insurance  policies and variable annuity
contracts  to  be  offered  by  insurance   companies  that  have  entered  into
participation   agreements   with  the  Fund   (the   "Participating   Insurance
Companies"); and

     WHEREAS,  the shares of the Fund are divided into several series of shares,
each series  representing  an  interest in a  particular  managed  portfolio  of
securities and other assets (the "Portfolios"); and

     WHEREAS, the Fund has applied for an order from the Securities and Exchange
Commission ("SEC") granting Participating Insurance Companies (as defined in the
Fund's  application for such order) and their separate accounts  exemptions from
the  provisions of sections  9(a),  13(a),  15(a) and 15(b) of the 1940 Act, and
Rules  6e-2(b)(15) and  6e-3(T)(b)(15)  thereunder,  to the extent  necessary to
permit  shares  of the  Fund to be sold to and  held  by  variable  annuity  and
variable life insurance  separate  accounts of both affiliated and  unaffiliated
life insurance companies and certain qualified pension and retirement plans (the
"Exemptive Order"); and

     WHEREAS,  the Company has registered or will register certain variable life
insurance  policies  and/or variable  annuity  contracts under the 1933 Act (the
"Contracts"); and

     WHEREAS, the Company has registered or will register each Account as a unit
investment trust under the 1940 Act; and

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


                                   ARTICLE I.
                               Sale of Fund Shares

     1.1.  The Fund  shall  make  [Class  1/Class  2] shares  of its  Portfolios
available to the Accounts at the net asset value next computed  after receipt of
such purchase  order by the Fund (or its agent),  as  established  in accordance
with  the  provisions  of  the  then  current  prospectus  of the  Portfolio  or
Portfolios.  Shares of a  particular  Portfolio  of the Fund shall be ordered in
such  quantities  and at such times as determined by the Company to be necessary
to meet the  requirements  of the  Contracts.  The  Directors  of the Fund  (the
"Directors")  may  refuse to sell  shares of any  Portfolio  to any  person,  or
suspend or terminate  the offering of shares of any  Portfolio if such action is
required by law or by regulatory  authorities having  jurisdiction or is, in the
sole  discretion  of the  Directors  acting in good  faith and in light of their
fiduciary duties under federal and any applicable  state laws,  necessary in the
best interests of the shareholders of such Portfolio.

     1.2. The Fund will redeem any full or  fractional  shares of any  Portfolio
when  requested  by the  Company on behalf of an Account at the net asset  value
next  computed  after  receipt  by the Fund (or its  agent) of the  request  for
redemption, as established in accordance with the provisions of the then current
prospectus  of the Fund.  The Fund shall  make  payment  for such  shares in the
manner  established from time to time by the Fund, but in no event shall payment
be delayed for a greater period than is permitted by the 1940 Act.

     1.3. For the purposes of Sections 1.1 and 1.2, the Fund hereby appoints the
Company as its agent for the limited purpose of receiving and accepting purchase
and  redemption  orders  resulting  from  investment  in and payments  under the
Contracts.  Receipt by the Company shall constitute receipt by the Fund provided
that (i) such orders are received by the Company in good order prior to the time
the net  asset  value  of each  Portfolio  is  priced  in  accordance  with  its
prospectus  and (ii) the Fund  receives  notice of such orders by 10:00 a.m. New
York time on the next following  Business Day. "Business Day" shall mean any day
on which the New York Stock  Exchange  is open for trading and on which the Fund
calculates its net asset value pursuant to the rules of the SEC.

     1.4.  Purchase  orders that are  transmitted to the Fund in accordance with
Section 1.3 shall be paid for on the same  Business  Day that the Fund  receives
notice of the order.  Payments  shall be made in federal  funds  transmitted  by
wire.


                                       2

     1.5. Issuance and transfer of the Fund's shares will be by book entry only.

ordered from the Fund will be recorded in the appropriate title for each Account
or the appropriate subaccount of each Account.

     1.6.  The Fund shall  furnish  prompt  notice to the  Company of any income
dividends  or capital  gain  distributions  payable on the  Fund's  shares.  The
Company  hereby  elects to receive all such income  dividends  and capital  gain
distributions  as are payable on a Portfolio's  shares in  additional  shares of
that  Portfolio.  The Fund shall  notify the  Company of the number of shares so
issued as payment of such dividends and distributions.

     1.7.  The Fund shall make the net asset value per share for each  Portfolio
available to the Company on a daily basis as soon as reasonably  practical after
the net asset  value per share is  calculated  and shall us its best  efforts to

     1.8.  The Fund agrees  that its shares  will be sold only to  Participating
Insurance Companies and their separate accounts and to certain qualified pension
and retirement  plans to the extent  permitted by the Exemptive Order. No shares
of any Portfolio will be sold directly to the general public. The Company agrees
that Fund shares will be used only for the purposes of funding the Contracts and
Accounts listed in Schedule A, as amended from time to time.

     1.9. The Fund and the Company  agree that they shall amend any provision of
this Agreement to the extent that it is inconsistent  with any condition imposed

     2.1. The Fund shall prepare and be responsible  for filing with the SEC and
any state  regulators  requiring such filing all shareholder  reports,  notices,

to which an issuer is subject on the issuance and transfer of its shares.

     2.2. At the option of the  Company,  the Fund shall  either (i) provide the
Company  (at the  Company's  expense)  with as many  copies of the Fund's or the
relevant Portfolio's current prospectus,  annual reports, semi-annual report and
other shareholder communications, including any amendments or supplements to any
of the foregoing,  as the Company shall reasonably  request; or (ii) provide the
Company  with a camera  ready  copy of such  documents  in a form  suitable  for
printing.  The Fund shall  provide the Company  with a copy of its  statement of
additional  information in a form suitable for  duplication by the Company.  The
Fund  (at  its   expense)   shall   provide  the  Company  with  copies  of  any
Fund-sponsored  proxy materials in such quantity as the Company shall reasonably

     2.3.  The Company  shall bear the costs of printing  and  distributing  the
Fund's  or  the  relevant  Portfolio's   prospectus,   statement  of  additional
information,  shareholder reports and other shareholder communications to owners
of and  applicants  for policies for which the Fund is serving or is to serve as
an investment  vehicle.  The Company shall bear the costs of distributing  proxy
materials (or similar  materials such as voting  solicitation  instructions)  to
Contract owners. The Company assumes sole  responsibility for ensuring that such
materials are delivered to Contract owners in accordance with applicable federal
and state securities laws.

     2.4 The Company agrees and  acknowledges  that the Fund's manager,  J. & W.
Seligman & Co. Incorporated ("Seligman"), is the sole owner of the name and mark
"Seligman"  and that all use of any  designation  comprised  in whole or part of
Seligman (a "Seligman  Mark") under this Agreement shall inure to the benefit of
Seligman.  Except as provided  in section  2.5,  the  Company  shall not use any
Seligman Mark on its own behalf or on behalf of the Accounts or Contracts in any
registration  statement,  advertisement,  sales  literature  or other  materials
relating to the  Accounts or  Contracts  without  the prior  written  consent of
Seligman.  Upon termination of this Agreement for any reason,  the Company shall
cease all use of any Seligman Mark(s) as soon as reasonably practicable.

     2.5. The Company shall fully disclose in each Contract  prospectus any fees
paid or to be paid by the relevant  Portfolio  under a plan adopted  pursuant to
Rule 12b-1 of the 1940 Act. The Company shall furnish, or cause to be furnished,
to the Fund or its designee,  a copy of each Contract prospectus or statement of
additional  information  in which  the Fund or  Seligman  is named  prior to the
filing of such document with the SEC. The Company shall furnish,  or shall cause
to be furnished, to the Fund or its designee,  each piece of advertising,  sales
literature or other promotional material in which the Fund or Seligman is named,
at least fifteen  Business Days prior to its use. No such material shall be used
if the  Fund or its  designee  reasonably  objects  to such use  within  fifteen
Business Days after receipt of such material.

     2.6. The Company shall not give any information or make any representations
or  statements  on  behalf of the Fund or  concerning  the Fund or  Seligman  in
connection   with  the  sale  of  the  Contracts   other  than   information  or
representations  contained  in and  accurately  derived  from  the  registration
statement or prospectus for the Fund shares (as such registration  statement and
prospectus  may be amended or  supplemented  from time to time),  reports of the
Fund,  Fund-sponsored  proxy  statements,   or  in  any  advertisements,   sales
literature or other  promotional  material approved by the Fund or its designee,
except as  required  by legal  process  or  regulatory  authorities  or with the
written permission of the Fund or its designee.

     2.7. The Fund shall not give any information or make any representations or
statements on behalf of the Company, or concerning the Company,  the Accounts or
the  Contracts  other  than  information  or  representations  contained  in and
accurately  derived  from  the  registration  statement  or  prospectus  for the
Contracts  (as such  registration  statement  and  prospectus  may be amended or
supplemented  from time to time),  or in  materials  approved by the Company for
distribution  including  advertisements,  sales literature or other  promotional


                                       4

materials, except as required by legal process or regulatory authorities or with
the written permission of the Company.

     2.8. So long as, and to the extent that the SEC  interprets the 1940 Act to
require  pass-through voting privileges for variable  policyowners,  the Company
will provide  pass-through  voting  privileges to owners of policies  whose cash
values are invested, through the Accounts, in shares of the Fund. The Fund shall
require all Participating  Insurance Companies to calculate voting privileges in
the same manner and the  Company  shall be  responsible  for  assuring  that the
Accounts calculate voting privileges in the manner established by the Fund. With
respect to each  Account,  the Company  will vote shares of the Fund held by the
Account  and for  which no  timely  voting  instructions  for  policyowners  are
received  as well as shares it owns that are held by that  Account,  in the same
proportion  as those  shares for which voting  instructions  are  received.  The
Company and its agents will in no way recommend or oppose or interfere  with the
solicitation  of proxies for Fund shares  held by  Contract  owners  without the
prior written  consent of the Fund,  which consent may be withheld in the Fund's
sole discretion.

     2.9  The  Company  shall  establish  and  disclose  to  Contract  owners  a
reasonable policy designed to discourage  frequent and disruptive  purchases and
redemptions of Fund shares by Contract  owners and shall cooperate with the Fund
to minimize the impact on the Fund of such transactions.

                                  ARTICLE III.

                                   ARTICLE IV.
                               Potential Conflicts

     4.1. The parties  acknowledge  that the Fund's shares may be made available
for investment to other Participating  Insurance Companies and qualified pension
and retirement  plans  ("Qualified  Plans").  In such event,  the Directors will
monitor  the Fund for the  existence  of any  material  irreconcilable  conflict
between the  interests of the  contract  owners of all  Participating  Insurance
Companies and of Qualified Plans. An irreconcilable  material conflict may arise
for a variety  of  reasons,  including:  (a) an  action  by any state  insurance
regulatory  authority;  (b) a change in applicable  federal or state  insurance,
tax, or securities  laws or  regulations,  or a public  ruling,  private  letter
ruling,  no-action or interpretative letter, or any similar action by insurance,
tax, or securities  regulatory  authorities;  (c) an  administrative or judicial
decision in any relevant proceeding;  (d) the manner in which the investments of
any Portfolio are being managed;  (e) a difference in voting  instructions given
by variable annuity contract and variable life insurance contract owners; or (f)
a decision  by an insurer to  disregard  the  voting  instructions  of  contract
owners.  The Directors  shall promptly inform the Company if they determine that
an irreconcilable material conflict exists and the implications thereof.

     4.2.  The  Company  agrees to  promptly  report any  potential  or existing
conflicts  of which it is aware to the  Directors.  The Company  will assist the
Directors in carrying out their  responsibilities  under the Exemptive  Order by
providing  the  Directors  with all  information  reasonably  necessary  for the
Directors  to  consider  any  issues  raised  including,  but  not  limited  to,
information  as to a decision by the Company to disregard  Contact  owner voting
instructions.

     4.3 If it is  determined by a majority of the  Directors,  or a majority of
its disinterested Directors, that a material irreconcilable conflict exists that
affects the interests of Contract owners, the Company shall, in cooperation with
other Participating Insurance Companies whose contract owners are also affected,
at its expense and to the extent  reasonably  practicable  (as determined by the
Directors)  take  whatever  steps  are  necessary  to remedy  or  eliminate  the
irreconcilable material conflict, which steps could include: (i) withdrawing the
assets  allocable to some or all of the Accounts  from the Fund or any Portfolio
and reinvesting such assets in a


                                       6
<PAGE>


different investment medium, including (but not limited to) another Portfolio of
the Fund, or submitting the question of whether or not such  segregation  should
be implemented to a vote of all affected  Contract  owners and, as  appropriate,
segregating the assets of any appropriate group (i.e., variable annuity contract
owners or variable,  life insurance  contract owners that votes in favor of such
segregation,  or offering to the affected  Contract  owners the option of making
such a change;  and (ii)  establishing  a new registered  management  investment
company or managed separate account.

     4.4. If a material  irreconcilable conflict arises because of a decision by
the Company to disregard  Contract owner voting  instructions  and that decision
represents a minority  position or would  preclude a majority  vote, the Company
may be required,  at the Fund's  election,  to withdraw the affected  Account if
requested by the Fund's Directors, terminate this Agreement with respect to such
Account within six months after the Directors inform the Company in writing that
it has  determined  that such  decision  has  created a material  irreconcilable
conflict;  provided,  however  that such  withdrawal  and  termination  shall be
limited to the extent required by the foregoing material irreconcilable conflict
as determined  by a majority of the  disinterested  Directors.  Until the end of
such six month period, the Fund shall continue to accept and implement orders by
the Company for the purchase and redemption of shares of the Fund.

     4.5. If a material  irreconcilable  conflict  arises  because a  particular
state insurance  regulator's  decision  applicable to the Company conflicts with
the  majority of other state  regulators,  then the Company  will  withdraw  the
affected  Account's  investment  in the Fund and,  if  requested  by the  Fund's
Directors,  terminate  this  Agreement  with respect to such Account  within six
months after the Directors  inform the Company in writing that it has determined
that such decision has created an irreconcilable  material  conflict;  provided,
however,  that such  withdrawal and  termination  shall be limited to the extent
required by the foregoing  material  irreconcilable  conflict as determined by a
majority of the disinterested Directors. Until the end of such six month period,
the Fund shall  continue to accept and  implement  orders by the Company for the
purchase and redemption of shares of the Fund.

     4.6. For purposes of Sections 4.3 through 4.6 of this Agreement, a majority
of the  disinterested  Directors  shall  determine  whether any proposed  action
adequately remedies any irreconcilable  material conflict,  but in no event will
the Company be required to establish a new funding  medium for the  Contracts if
an offer to do so has been  declined by vote of a majority  of  Contract  owners
materially  adversely affected by the irreconcilable  material conflict.  In the
event that the Directors  determine that any proposed action does not adequately
remedy any irreconcilable  material conflict, then the Company will withdraw the
Account's  investment in the Fund and terminate  this  Agreement  within six (6)
months  after the  Directors  inform the  Company  in  writing of the  foregoing
determination;  provided, however, that such withdrawal and termination shall be
limited to the extent required by any such material  irreconcilable  conflict as
determined by a majority of the disinterested Directors.

     4.7.  The  Company  and  Seligman  shall at least  annually  submit  to the
Directors  such  reports,  materials  or data as the  Directors  may  reasonable
request so that the Directors  may fully


                                       7
<PAGE>


carry out the duties imposed upon them by the Exemptive Order, and said reports,
materials and data shall be submitted more  frequently if deemed  appropriate by
the Directors.

     4.8. If and to the extent that Rule 6e-2 and Rule 6e-3(T) are  amended,  or
Rule 6e-3 is adopted, to provide exemptive relief from any provision of the 1940
Act or the rules promulgated  thereunder with respect to mixed or shared funding
(as defined in the Exemptive Order) on terms and conditions materially different
from  those  contained  in  the  Exemptive  Order,  then  the  Fund  and/or  the
Participating Insurance Companies, as appropriate,  shall take such steps as may
be necessary to comply with Rules 6e-2 and 6e-3(T),  as amended,  and Rule 6e-3,
as adopted, to the extent such rules are applicable.

                                   ARTICLE V.

and each person,  if any, who controls the Company within the meaning of Section

     and accurately derived from written information furnished to the Company by
     or on behalf of the Fund; or

          (d) arise out of or result from any failure by the Fund to provide the
     services  or  furnish  the  materials  required  under  the  terms  of this
     Agreement; or

     Fund.

     5.3.   Neither  the  Company  nor  the  Fund  shall  be  liable  under  the
indemnification  provisions of sections 5.1 or 5.2, as applicable,  with respect
to any Losses incurred or assessed against an Indemnified  Party that arise from
such Indemnified Party's willful  misfeasance,  bad faith or gross negligence in
the  performance  of  such  Indemnified  Party's  duties  or by  reason  of such
Indemnified  Party's  reckless  disregard  of  obligations  or duties under this
Agreement.

shall have  notified the other party in writing  within a reasonable  time after
the summons,  or other first written  notification,  giving  information  of the
nature of the claim shall have been served  upon or  otherwise  received by such
Indemnified Party (or after such Indemnified Party shall have received notice of
service upon or other  notification  to any  designated  agent),  but failure to
notify the party against whom  indemnification is sought of any such claim shall
not relieve that party from any liability  which it may have to the  Indemnified
Party in the absence of sections 5.1 and 5.2.

     5.5. In case any such action is brought  against the  Indemnified  Parties,
the indemnifying party shall be entitled to participate,  at its own expense, in
the defense of such  action.  The  indemnifying  party also shall be entitled to

named in the action. After notice from the indemnifying party to the Indemnified
Party of an election to assume such defense,  the  Indemnified  Party shall bear

indemnifying  party  will not be  liable to the  Indemnified  Party  under  this
Agreement for any legal or other  expenses  subsequently  incurred by such party
independently in connection with the defense thereof other than reasonable costs
of investigation.

Seligman Portfolios, Inc.,
100 Park Avenue,
New York, N.Y. 10017.

Dear Sirs:

     In connection with Post-Effective Amendment No. 27 to the Registration
Statement on Form N-1A (File No. 33-15253) of Seligman Portfolios, 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 2 shares (the "Shares"), we, as your counsel, have examined
such corporate records, certificates and other documents, and such questions of
law, as we have considered necessary or appropriate for the purposes of this
opinion.

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

Seligman Portfolios, Inc.                                                  - 2 -


between the number of shares that the Fund is authorized to issue and the total
number of shares of all classes outstanding at such time.

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

     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,

                                                          /s/SULLIVAN & CROMWELL

                         CONSENT OF INDEPENDENT AUDITORS

Highlights" and "General Information - Independent Auditors" and to the

                   SHAREHOLDER SERVICING AND DISTRIBUTION PLAN

                                 March 16, 2000

     Section 1. Each series of Seligman Portfolios,  Inc. (the "Fund") listed in
Schedule A hereto  (each,  a "Portfolio"  and  collectively,  the  "Portfolios")
offers its shares to separate accounts  ("Accounts") of participating  insurance
companies to fund benefits of variable  annuity  contracts and, upon the receipt
of an exemptive order from the Securities and Exchange Commission, variable life
insurance contracts  (collectively,  the "Contracts").  Each Portfolio may pay a
fee to Seligman  Advisors,  Inc.,  the principal  underwriter of its shares (the
"Distributor"),  for shareholder  services and distribution  assistance provided
with respect to Class 2 shares of such Portfolio. As a result, each Portfolio is
adopting this Shareholder  Servicing 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,  each  Portfolio  may pay a  shareholder
servicing and  distribution  fee to the  Distributor  of up to .25% on an annual
basis,  payable monthly, of the average daily net assets attributable to Class 2
shares of such Portfolio.  The Distributor will use this fee to make payments to
participating  insurance  companies or their  affiliates  for services  that the
participating  insurance companies provide to Contract owners of Class 2 shares,
including,  but not limited to (i) the printing and delivering of  prospectuses,
statements of additional information,  shareholder reports, proxy statements and
marketing  materials related to the Portfolios to current Contract owners,  (ii)
providing facilities to answer questions from current Contract owners of Class 2
shares about the Portfolios, (iii) receiving and answering correspondence,  (iv)
providing  information  to J.  & W.  Seligman  & Co.  Incorporated,  the  Fund's
investment manager (the "Manager"), and to Contract owners with respect to Class
2  shares  of the  Portfolios  attributable  to  Contract  owner  Accounts,  (v)
complying with federal and state securities laws pertaining to the sale of Class
2 shares of the  Portfolios,  and (vi) assisting  Contract  owners in completing
application  forms and  selecting  dividend and other Account  options,  and for
distribution  related services.  Fees received  hereunder may not be used to pay
any allocation of overhead of the Distributor.  Fees paid by Class 2 shares of a
Portfolio  may not be used to pay  expenses  incurred  solely in  respect of any
other  class of any  Portfolio.  The fees  payable  to  participating  insurance
companies  from time to time shall,  within such limits,  be  determined  by the
Directors of the Fund.

     Section 3. 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 Portfolios.

     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 Fund  with  respect  to a
Portfolio 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  Portfolio's
Class 2 shares. If this Plan is terminated in respect of a Portfolio, no amounts
(other than amounts accrued but not yet paid) would be owed by such Portfolio to
the Distributor.

     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  participating  insurance company 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 a Portfolio 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 2 shares of that  Portfolio,  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


                                       1
<PAGE>


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.

     Section  9.  The  Portfolios  are  not  obligated  to pay  any  shareholder
servicing or  distribution  expenses in excess of the fee described in Section 2
hereof.

     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.

          to  Owners  with  respect  to  Class 2  shares  attributable  to Owner
          accounts;  complying with federal and state securities laws pertaining
          to the  sale  of  Class  2  shares;  assisting  Owners  in  completing
          application   forms  and   selecting   account   options;   and  other
          distribution related services.

     2.   The Company will provide  such office space and  equipment,  telephone
          facilities, and personnel as may be reasonably necessary or beneficial
          in order to provide such services to Owners.

     3.   Neither the Company nor any of its employees or agents are  authorized
          to  make  any   representation   concerning   the  Portfolios  or  the
          Portfolios'  Class 2 shares except those contained in the then current
          Prospectus, copies of which will be supplied by Seligman Advisors. The
          Company shall have no authority to act as agent for Seligman  Advisors
          or the Portfolios.

     4.   In consideration of the services and facilities  described herein, the
          Company  shall be  entitled  to receive a  shareholder  servicing  and
          distribution  fee in an amount  up to .25% on an  annual  basis of the
          average  daily  net  assets  attributable  to  Class 2  shares  of the
          Portfolios.  Seligman  Advisors  has no  obligation  to make  any such
          payment  and the  Company  agrees  to waive  payment  of its fee until
          Seligman  Advisors is in receipt of the fee from the  Portfolios.  The
          payment  of  fees  has  been  authorized  pursuant  to  a  Shareholder
          Servicing and Distribution Plan (the "Plan") approved by the Directors
          of the Fund and the  shareholders  of the  Portfolios  pursuant to the
          requirements  of Rule 12b-1 under the  Investment  Company Act of 1940
          (the "Act") and such authorizations may be withdrawn at any time.

     5.   It is understood  that the Fund reserves the right,  at its discretion
          and without notice,  to suspend or withdraw the sale of Class 2 shares
          of the Portfolios.  This Agreement shall not be construed to authorize
          the Company to perform  any act that  Seligman  Advisors  would not be
          permitted to perform under the Distribution and Shareholder  Servicing
          Agreement between the Fund and Seligman Advisors.

     6.   Subject to the proviso in Section 6 of the Plan,  this Agreement shall
          continue  until  December  31 of the year in which  the Plan has first
          been  approved by  shareholders  and through  December 31 of each year
          thereafter provided such continuance is specifically approved at least
          annually by a vote of a majority of (i) the Fund's  Directors and (ii)
          the  Qualified  Directors  cast in person at a meeting  called for the
          purpose  of voting on such  approval  and  provided  further  that the
          Company shall not have notified  Seligman Advisors in writing at least
          60 days prior to the anniversary date of the previous continuance that
          it does not desire such continuance.  This Agreement may be terminated
          at any  time  without  payment  of any  penalty  with  respect  to any
          Portfolio by vote of a majority of the Qualified Directors, or by vote
          of a majority of the outstanding voting securities of such Portfolio's
          Class 2 shares, on 60 days' written notice to the Company and Seligman
          Advisors. Notwithstanding anything contained herein, in the event that
          the  Plan  shall be  terminated  or any  part  thereof  shall be found
          invalid or ordered terminated by any regulatory or judicial authority,
          or the Company shall fail to perform the services contemplated by this
          Agreement,  such  determination  to be made in good faith by  Seligman
          Advisors,  this Agreement may be terminated  effective upon receipt of
          written  notice  thereof  by the  Company.  This  Agreement  will also
          terminate automatically in the event of its assignment.

          100 Park Avenue,  New York, New York 10017.  Any notice to the Company
          shall be duly  given if mailed  or  telegraphed  to it at the  address
          shown below.

     8.   As used in this Agreement, the terms "assignment", "interested person"
          and "vote of a majority of the outstanding  voting  securities"  shall
          have the respective meanings specified in the Act and in the rules and
          regulations  thereunder and the term "Qualified  Directors" 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 Plan or in
          any agreements related to the Plan.

     9.   This Agreement  shall be governed by and construed in accordance  with
          the laws of the State of New  York.  Anything  herein to the  contrary
          notwithstanding,  this Agreement shall not be construed to require, or
          to  impose  any  duty  upon,  any of the  parties  to do  anything  in

                                   SCHEDULE A

                                   PORTFOLIOS

                   [Portfolios being serviced by the Company]


















                            SELIGMAN PORTFOLIOS, INC.

                Plan for Multiple Classes of Shares (two classes)


     THIS PLAN, as it may be amended from time to time,  sets forth the separate
arrangement  and expense  allocation of each class of shares (a "Class") of each
Portfolio listed on Schedule I hereto (each, a "Portfolio" and collectively, the
"Portfolios"),  of Seligman  Portfolios,  Inc. (the  "Fund").  The Plan has been
adopted  pursuant to Rule 18f-3(d) under the Investment  Company Act of 1940, as
amended (the "Act"),  by a majority of the Board of Directors  ("Directors")  of
the Fund,  including a majority of the Directors who are not interested  persons
of the Fund  within the meaning of Section  2(a)(19) of the Act  ("Disinterested
Directors").  Any  material  amendment  to this  Plan is  subject  to the  prior
approval  of the Board of  Directors  of the Fund,  including  a majority of the
Disinterested Directors.

1.   General

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

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

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

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

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

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

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

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

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


                                      -1-
<PAGE>


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

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

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

          ii.  Income and  expenses  of a Portfolio  not  charged  directly to a
               particular  Class  shall  be  allocated  to  each  Class  of that
               Portfolio on the following basis:

                    (a) Except for Cash  Management  Portfolio,  on the basis of
               the  aggregate net asset value of the Record Shares of each Class
               in relation to the  aggregate net asset value of Record Shares of
               the Portfolio.

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

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

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

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


                                      -2-
<PAGE>


          relating to the Classes  will be borne  exclusively  by each Class and
          except that any Class Level  Expenses shall be borne by the applicable
          Class.

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

2.   Specific Arrangements for Each Class

     The  following  arrangements  regarding  shareholder  services  and expense
allocation  shall be in effect  with  respect  to the Class 1 shares and Class 2
shares of each Portfolio.  The following descriptions are qualified by reference
to  the  more  detailed  description  of  such  arrangements  set  forth  in the
prospectuses and statement of additional information relating to the Portfolios,
as the same may from time to time be amended or  supplemented,  provided that no
relevant  prospectus  or  statement  of  additional  information  may modify the
provisions of this Plan applicable to Rule 12b-1 fees or Class Level Expenses.

(a)  Class 1 Shares

     i.   Class 1  shares  shall  not be  subject  to a Rule  12b-1  shareholder
          servicing and distribution fee.

     ii.  Special  Expenses  attributable  to the Class 1 shares,  except  those
          determined  by the  Directors  not to be Class  Level  Expenses of the
          Class 1 shares in accordance  with paragraph  1.B.iv.,  shall be Class
          Level Expenses and attributed  solely to the Class 1 shares.  No other
          expenses  shall be  treated  as Class  Level  Expenses  of the Class 1
          shares.

(b)  Class 2 Shares

     i.   Class 2 shares shall be subject to a Rule 12b-1 shareholder  servicing
          and distribution fee of up to 0.25% of average daily net assets.

     ii.  Special  Expenses  attributable  to the Class 2 shares,  except  those
          determined  by the  Directors  not to be Class  Level  Expenses of the
          Class 2 shares in accordance  with paragraph  1.B.iv.,  shall be Class
          Level Expenses and attributed  solely to the Class 2 shares.  No other
          expenses  shall be  treated  as Class  Level  Expenses  of the Class 2
          shares.

                                 CODE OF ETHICS

                       J. & W. Seligman & Co. Incorporated
                             Seligman Advisors, Inc.
                             Seligman Services, Inc.
                               Seligman Data Corp.
                          Seligman International, Inc.
                        Seligman International UK Limited
                   The Seligman Group of Investment Companies

                                 I. Introduction

A  primary  duty  of  all  directors,   officers  and  employees   (collectively
"Employees")  of J. & W.  Seligman  & Co.  Incorporated,  its  subsidiaries  and
affiliates  (collectively,  "Seligman") is to be faithful to the interest of the
various  Seligman  advisory  clients,  including the registered and unregistered
companies  advised  by  Seligman  (collectively,  "Clients").  Directors  of the
Seligman  Registered  Investment  Companies  also  have a duty  to the  Seligman
Registered  Investment  Companies  and  their  shareholders.   Persons  who  are
Disinterested Directors are "Employees" for purposes of this Code of Ethics.

Through  the  years,  Seligman  and its  predecessor  organizations  have  had a
reputation of maintaining  the highest  business and ethical  standards and have
been favored with the confidence of investors and the financial community.  Such
a  reputation  and  confidence  are not  easily  gained  and are  among the most
precious assets of Seligman.  In large measure,  they depend on the devotion and
integrity with which each Employee discharges his or her responsibilities. Their
preservation and development  must be a main concern of each Employee,  and each
Employee  has a primary  obligation  to avoid any action or activity  that could
produce  conflict  between  the  interest  of the  Clients  and that  Employee's
self-interest.

The  purpose of this Code of Ethics  ("Code")  is to set forth the  policies  of
Seligman in the matter of conflicts  of interest and to provide a formal  record
for each  Employee's  reference  and  guidance.  This Code is also  designed  to
prevent  any act,  practice or course of  business  prohibited  by the rules and
regulations governing our industry.

Each Employee  owes a fiduciary  duty to each Client.  Therefore,  all Employees
must  avoid  activities,  interests  and  relationships  that  might  appear  to
interfere with making decisions in the best interest of the Clients.

As an Employee, you must at all times:

1.   Avoid  serving  your  own  personal  interests  ahead of the  interests  of
     Clients.  You may not cause a Client to take action, or not to take action,
     for your personal benefit rather than the Client's benefit.

2.   Avoid  taking  inappropriate  advantage  of your  position.  The receipt of
     investment  opportunities,   perquisites  or  gifts  from  persons  seeking
     business  with  Clients  or with  Seligman  could  call into  question  the
     exercise of your better judgment.  Therefore,  you must not give or receive
     benefits that would  compromise your ability to act in the best interest of
     the Clients.

3.   Conduct all personal  Securities  Transactions  in full compliance with the
     Code,  including  the  pre-authorization  and reporting  requirements,  and
     comply fully with the Seligman Insider Trading Policies and Procedures (See
     Appendix A).

While Seligman  encourages you and your families to develop personal  investment
programs, you must not take any action that could cause even the appearance that
an unfair or improper  action has been taken.  Accordingly,  you must follow the
policies set forth below with respect to trading in your  Account(s).  This Code
places  reliance on the good sense and judgment of you as an Employee;  however,
if you are unclear as to the Code's  meaning,  you should seek the advice of the

any trades that indicate a violation of your fiduciary duties.

Application of the Code to Disinterested Directors

Disinterested  Directors  are only  subject  to the  reporting  requirements  in
Section III.5(b) of the Code.  Disinterested  Directors are not subject to other
provisions  of the Code  but are  subject  to the  requirements  of the  federal

securities of an issuer while in possession of material non-public information.

                      III. Personal Securities Transactions

1.   Prohibited Transactions

     These apply to all of your Accounts.

     (a)  Seven-Day  Blackout:  If  you  are a  member  of an  Investment  Team,
          Securities  Transactions  are  prohibited  within seven  calendar days
          either  before or after the purchase or sale of the relevant  security
          (or an  Equivalent  Security) by a Client whose  Account is managed by
          your Investment Team.

     (b)  Intention  to Buy or Sell for  Clients:  Securities  Transactions  are
          prohibited at a time when you intend, or know of another's  intention,
          to purchase  or sell that  Security  (or an  Equivalent  Security)  on
          behalf of a Client.

     (c)  Sixty-Day  Holding  Period:  Profits on Securities  Transactions  made
          within a sixty-day  period are prohibited and must be disgorged.  This
          is a prohibition of short term trading. Specifically,

          o    Purchase  of a  Security  within  60  days  of  your  sale of the
               Security  (or an  Equivalent  Security),  at a price that is less
               than the price in the previous  sale is  prohibited.

          o    Sale of a Security  within the 60 day period of your  purchase of
               the  Security  (or an  Equivalent  Security),  at a price that is
               greater  than the price in the previous  purchase is  prohibited.
               Examples are as follows:

          1.   Employee  purchases 100 shares of XYZ ($10 a share) on January 1.
               Employee  sells 100 shares of XYZ ($15 a share) on  February  15.
               Employee must disgorge $500.

          2.   Employee  purchases 100 shares of XYZ ($10 a share) on January 1.
               Employee  purchases 50 shares of XYZ ($12 a share) on January 30.
               Employee  sells  50  shares  of XYZ ($15 a  share)  on March  15.
               Employee  must  disgorge  $150.  (The  March  15 sale  may not be
               matched to the January 1 purchase).

          3.   Employee purchases 100 shares of XYZ ($10 a share) on January 1.
               Employee sells 100 shares of XYZ ($10 a share) on February 1.
               Employee purchases 100 shares of XYZ ($9 a share) on March 1
               Employee must disgorge $100.
               (The February 1 sale is  permissible  because no profit was made.
               However,  the March 1 purchase is matched  against the February 1
               sale resulting in a $100 profit).

     (d)  Restricted Transactions: Transactions in a Security are prohibited (i)
          on the day of a purchase or sale of the Security by a Client,  or (ii)
          anytime a Client's  order in the Security is open on the trading desk.
          Other  Securities  may be  restricted  from  time to  time  as  deemed
          appropriate by the Law and Regulation Department.


<PAGE>


     (e)  Short Sales:  If you are a member of an Investment  Team,  you may not
          engage  in any  short  sale  of a  Security  if,  at the  time  of the
          transaction,  any Client  managed by your Team has a long  position in
          that same Security.  However,  this  prohibition  does not prevent you
          from engaging short sales against the box and covered call writing, as
          long as these  personal  trades are in  accordance  with the sixty-day
          holding period described above.

     (f)  Public Offerings:  Acquisitions of Securities in initial and secondary
          public  offerings are  prohibited,  unless granted an exemption by the
          Director of Compliance.  An exemption for an initial  public  offering
          will only be granted in certain  limited  circumstances,  for example,
          the demutualization of a savings bank.

     (g)  Private  Placements:  Acquisition of Securities in a private placement
          is  prohibited  absent  prior  written  approval  by the  Director  of
          Compliance.

     (h)  Market  Manipulation:   Transactions  intended  to  raise,  lower,  or
          maintain the price of any Security or to create a false  appearance of
          active trading are prohibited.

     (i)  Inside Information:  You may not trade, either personally or on behalf
          of  others,  on  material,   non-public   information  or  communicate
          material,  non-public  information to another in violation of the law.
          This policy  extends to  activities  within and outside your duties at
          Seligman. (See Appendix A).

2.   Maintenance of Accounts

     All  Accounts  that have the ability to engage in  Securities  Transactions
     must be  maintained  at Ernst &  Company  (Investec)  and/or  the  specific
     Merrill Lynch branch office located at 712 Fifth Avenue,  New York, NY. You
     are  required to notify the  Director of  Compliance  of any change to your
     account  status.   This  includes   opening  a  new  Account,   converting,
     transferring  or  closing  an  existing  account  or  acquiring  Beneficial
     Interest in an Account  through  marriage or otherwise.  You must place all
     orders for  Securities  Transactions  in these  Account(s)  with the Equity
     Trading Desk or the  appropriate  Fixed Income Team as set forth in Section
     III.3 ("Trade Pre-authorization Requirements").

     The  Director  of  Compliance   may  grant   exceptions  to  the  foregoing
     requirements  on a case by case basis.  All requests for exceptions must be
     applied  for in writing  and  submitted  for  approval  to the  Director of
     Compliance and will be subject to certain conditions.

3.   Trade Pre-authorization Requirements

     All  Securities  Transactions  in an Employee  Account or Employee  Related
     Account must be  pre-authorized,  except for  Securities  Transactions  set
     forth in Section III.4 ("Exempt Transactions").

     (a)  Trade  Authorization  Request  Form:  Prior to entering an order for a
          Securities  Transaction  in an Employee  Account or  Employee  Related
          Account,  which is subject to  pre-authorization,  you must complete a
          Trade Authorization  Request Form (set forth in Appendix B) and submit
          the  completed  Form  (faxed or hand  delivered)  to the  Director  of
          Compliance (or designee).

     (b)  Review of the Form and Trade Execution:  After receiving the completed
          Trade  Authorization  Request  Form,  the Director of  Compliance  (or
          designee)  will  review the  information  and,  as soon as  practical,
          determine  whether to authorize the proposed  Securities  Transaction.
          The  authorization,  date  and  time  of  the  authorization  must  be
          reflected on the Form. Once approved the order may then be executed by
          Equity Trading Desk or the appropriate  Fixed Income Team,  except for
          accounts for which an exemption was granted under Section III.2.


<PAGE>


     (c)  Length of Trade Authorization Approval: Any authorization, if granted,
          is effective until the earliest of (i) its revocation,  (ii) the close
          of business on the day from which  authorization  was granted or (iii)
          your discovery that the information in the Trade Authorization Request
          Form is no longer  accurate.  If the  Securities  Transaction  was not
          placed or executed within that period, a new pre-authorization must be
          obtained.  A new  pre-authorization  need not be  obtained  for orders
          which cannot be filled in one day due to an illiquid  market,  so long
          as such  order  was  placed  for  execution  on the  day the  original
          pre-authorization was given.

     No order for a Securities  Transaction  may be placed prior to the Director
     of Compliance (or designee) receiving the completed Trade Pre-authorization
     Form and approving the transaction.  In some cases,  trades may be rejected
     for a reason that is confidential.

4.   Exempt Transactions

     The  prohibitions of this Code shall not apply to the following  Securities
     Transactions in your Account(s):

     (a)  Purchases or sales of Securities which are  non-volitional  (i.e., not
          involving any investment decision or recommendation).

     (b)  Purchases of Securities  through  certain  corporate  actions (such as
          stock  dividends,  dividend  reinvestments,   stock  splits,  mergers,
          consolidations,  spin-offs, or other similar corporate reorganizations
          or distributions generally applicable to all holders of the same class
          of Securities).

     (c)  Purchases of Securities effected upon the exercise of rights issued by
          an issuer pro rata to all holders of a class of its Securities, to the
          extent such rights were acquired from the issuer.

     (d)  Purchases or sales of open-end registered investment  companies,  U.S.
          Government   Securities  and  money  market  instruments  (e.g.,  U.S.
          Treasury  Securities,   bankers  acceptances,   bank  certificates  of
          deposit, commercial paper and repurchase agreements).

     (e)  Purchases  of  Securities  which  are  part of an  automatic  dividend
          reinvestment  plan or  stock  accumulation  plan;  however,  quarterly
          account  statement  of such  plans  must be  sent to the  Director  of
          Compliance.

     (f)  Securities  Transactions  that are  granted a prior  exemption  by the
          Director of Compliance,  the General Counsel or the Associate  General
          Counsel.

5.   Reporting

     (a)  You must  arrange for the Director of  Compliance  to receive from the
          executing broker, dealer or bank duplicate copies of each confirmation
          and account  statement for each Securities  Transaction in an Employee
          Account or Employee Related Account.

     (b)  If you are a  Disinterested  Director  you are  required to report the
          information specified below with respect to any Securities Transaction
          in any Securities  Account in which you have Beneficial  Interest,  if
          you knew, or in the ordinary course of fulfilling your official duties
          as a Disinterested  Director,  should have known,  that during 15 days
          immediately before or after the date of your transaction, the Security
          (or  Equivalent   Security)  was  purchased  or  sold  by  a  Seligman
          Registered  Investment Company or considered for purchase or sale by a
          Seligman Registered  Investment Company. Such report shall be made not
          later than 10 days after the end of the calendar  quarter in which the
          Transaction was effected and shall contain the following information:


<PAGE>


          (i)  The date of the transaction,  the name of the company, the number
               of shares, and the principal amount of each Security involved;

          (ii) The nature of the transaction (i.e., purchase,  sale or any other
               type of acquisition or disposition);

          (iii) The price at which the transaction was effected;

          (iv) The name of the broker,  dealer or bank with or through  whom the
               transaction was effected; and

          (v)  The date the report is submitted.

     (c)  You are required to disclose all Securities  beneficially owned by you
          within ten days of  commencement  of employment and at the end of each
          calendar year within 10 days thereafter (See Appendix C).

     (d)  You are also  required to disclose all  Employee and Employee  Related
          Securities  Accounts,  Private  Securities  Transactions  and  Outside
          Activities,   Affiliations  and  Investments   upon   commencement  of
          employment and annually thereafter (See Appendix D).

     (e)  Any  report  may  contain a  statement  that the  report  shall not be
          construed as an admission by you, that you have any direct or indirect
          beneficial ownership in the Security to which the report relates.

     (f)  The Director of Compliance or his designee will review all reports.

6.   Dealings with the Clients

     You should  not have any  direct or  indirect  investment  interest  in the
     purchase or sale of any Security or property from or to Clients.  This is a
     prohibition  against  dealings  between  you  and  the  Clients  and is not
     intended to preclude or limit investment  transactions by you in Securities
     or  property,  provided  such  transactions  are not in  conflict  with the
     provisions of this Code.

7.   Preferential Treatment, Favors and Gifts

     You are prohibited from giving and receiving gifts of significant  value or
     cost from any person or entity that does  business with or on behalf of any
     Client. You should also avoid  preferential  treatment,  favors,  gifts and
     entertainment  which  might,  or might  appear to,  influence  adversely or
     restrict the  independent  exercise of your best efforts and best judgments
     on  behalf  of the  Clients  or  which  might  tend  in any  way to  impair
     confidence  in Seligman  by Clients.  Cash Gifts that do not exceed $100 in
     value per person for a calendar year are permissible.  Ordinary  courtesies
     of  business  life,  or  ordinary  business  entertainment,  and  gifts  of
     inconsequential value are also permissible.  However, they should not be so
     frequent nor so extensive as to raise any question of impropriety.

8.   Outside  Business  Activities  and Service as a  Director,  Trustee or in a
     Fiduciary Capacity of any Organization

     You may not  engage  in any  outside  business  activities  or  serve  as a
     Director,  Trustee or in a fiduciary capacity of any organization,  without
     the prior written consent of the Director of Compliance.

     trading rights and/or employment.

     As part of any  sanction,  you may be  required to absorb any loss from the
     trade. Any profits realized,  as a result of your personal transaction that

  J. & W. Seligman & Co. Incorporated - Insider Trading Policies and Procedures

SECTION I.  BACKGROUND

Introduction

     United States law creates an affirmative duty on the part of broker-dealers
and investment advisers to establish,  maintain and enforce written policies and
procedures   that  provide  a  reasonable  and  proper  system  of  supervision,
surveillance and internal control to prevent the misuse of material,  non-public
information by the  broker-dealer,  investment  adviser or any person associated
with them. The purpose of these  procedures is to meet those  requirements.  The
following  procedures  apply  to  J.  & W.  Seligman  &  Co.  Incorporated,  its
subsidiaries  and  affiliates  (collectively,   "Seligman")  and  all  officers,
directors and employees (collectively, "Employees") thereof.

Statement of Policy

     No  Employee  may  trade,  either  personally  or on behalf of  others,  on
material, non-public information or communicate material, non-public information
to another in violation of the law. This policy extends to activities within and
outside their duties at Seligman.  Each Employee must read,  acknowledge receipt
and retain a copy of these procedures.

Inside Information

     The term "insider  trading" is not defined in the federal  securities laws,
but generally is used to refer to the use of material, non-public information to
trade in  securities  or to  communicate  material,  non-public  information  to
others.

     While the law concerning  insider  trading is not static,  it is understood
that the law generally prohibits:

     A.   trading by an insider,  while in  possession  of material,  non-public
          information, or

     B.   trading by a non-insider,  while  knowingly in possession of material,
          non-public information,  where the information either was disclosed to
          the  non-insider  in  violation  of  an  insider's  duty  to  keep  it
          confidential or was misappropriated, or

     C.   communicating material, non-public information to others.

     The elements of insider trading and the penalties for such unlawful conduct
are discussed below. If you have any questions after reviewing these procedures,
you should  consult the  Director of  Compliance,  General  Counsel or Associate
General Counsel.

1.   Who Is An Insider?

     The concept of "insider" is broad. It includes  Employees of a company.  In
     addition,  a person can be a "temporary insider" if he or she enters into a
     special confidential relationship in the conduct of a company's affairs and
     as a  result  is given  access  to  information  solely  for the  company's
     purposes.  A  temporary  insider can  include,  among  others,  a company's
     attorneys,  accountants,   consultants,  bank  lending  officers,  and  the
     Employees  of such  organizations.  In  addition,  Seligman  may  become  a
     temporary  insider of a company it advises or for which it  performs  other
     services.  According  to the Supreme  Court,  the  company  must expect the
     outsider to keep the disclosed non-public information


<PAGE>


confidential  and the  relationship  must at least  imply such a duty before the
outsider will be considered an insider.

2.   What Is Material Information?

     Trading  on inside  information  is not a basis for  liability  unless  the
     information  is material.  "Material  information"  generally is defined as
     information  for which there is a substantial  likelihood that a reasonable
     investor  would  consider  it  important  in making  his or her  investment
     decisions,  or information that is reasonably certain to have a substantial
     affect on the price of a company's  securities.  Information that Employees
     should consider material includes, but is not limited to: dividend changes,
     earnings  estimates,  changes in previously  released  earnings  estimates,
     significant   merger  or  acquisition   proposals  or   agreements,   major
     litigation, liquidation problems and extraordinary management developments.
     In addition,  information about major contracts or new customers could also
     qualify as material,  depending upon the importance of such developments to
     the company's financial condition or anticipated performance.

     Material  information does not have to relate to a company's business.  For
     example,  in Carpenter  v. U.S.,  408 U.S.  316 (1987),  the Supreme  Court
     considered  as  material  certain  information  about  the  contents  of  a
     forthcoming  newspaper  column that was expected to affect the market price
     of a Security.  In that case,  a Wall  Street  Journal  reporter  was found
     criminally  liable  for  disclosing  to others  the dates  that  reports on
     various  companies  would appear in the Journal and whether  those  reports
     would be favorable or not.

3.   What Is Non-Public Information?

     Information is non-public until it has been effectively communicated to the
     market  place.  One  must be able to point  to some  fact to show  that the
     information is generally public. For example, information found in a report
     filed with the SEC, or appearing in Dow Jones,  Reuters Economic  Services,
     The Wall Street Journal or other publications of general  circulation would
     be considered public. However, see Section II, Paragraph 2.

4.   Penalties for Insider Trading

     Penalties for trading on or communicating material,  non-public information
     are severe,  both for  individuals  involved in such  unlawful  conduct and
     their  employers.  A person can be subject to some or all of the  penalties
     below even if he or she does not  personally  benefit  from the  violation.
     Penalties include:

     -    Civil injunctions

     -    Disgorgement of profits

     -    Jail sentences

     -    Fines for the person who  committed the violation of up to three times
          the profit gained or loss avoided,  whether or not the person actually
          benefited, and

     -    Fines  for the  employer  or  other  controlling  person  of up to the
          greater of  $1,000,000  or three times the amount of the profit gained
          or loss avoided.

     In addition,  any violation of policies and procedures set forth herein can
be expected to result in serious sanctions by Seligman,  including  dismissal of
the persons involved.

SECTION II.  PROCEDURES

Procedures to Implement Policy Against Insider Trading.

     The following  procedures have been  established to assist the Employees of
Seligman  in  avoiding  insider  trading,  and to aid  Seligman  in  preventing,
detecting and imposing  sanctions  against  insider  trading.  Every Employee of
Seligman  must follow  these  procedures  or risk serious  sanctions,  including
dismissal,  substantial  personal liability and criminal penalties.  If you have
any  questions  about  these  procedures  you should  consult  the  Director  of
Compliance, the General Counsel or Associate General Counsel.

1.   Identifying Inside Information.

     Before trading for yourself or others (including  investment  companies and
     private Accounts managed by Seligman), in the securities of a company about
     which you may have potential inside information, ask yourself the following
     questions:

     a.   Is the  information  material?  Is this  information  that an investor
          would consider important in making his or her investment decisions? Is
          this information that would  substantially  affect the market price of
          the securities if generally disclosed?

     b.   Is the  information  non-public?  To whom  has this  information  been
          provided?  Has the information  been  effectively  communicated to the
          marketplace  in a publication  of general  circulation or does it fall
          within the circumstances set forth in paragraph 2 below.

     If, after  consideration  of the above, you believe that the information is
material and non-public,  or if you have questions as to whether the information
is material and non-public, you should take the following steps:

     c.   Report the matter  immediately to the Director of Compliance,  General
          Counsel or Associate General Counsel.

     d.   Do not  purchase  or sell the  securities  on  behalf of  yourself  or
          others,  including investment companies or private Accounts managed by
          Seligman.

     e.   Do not communicate the  information  inside or outside  Seligman other
          than to the  Director  of  Compliance,  General  Counsel or  Associate
          General Counsel.

     f.   After the Director of Compliance, General Counsel or Associate General
          Counsel has reviewed the issue, you will be instructed to continue the
          prohibitions against trading and communication, or you will be allowed
          to trade and communicate the information.

2.   Important Specific Examples

     a.   If you have a telephone  or  face-to-face  conversation  with a senior
          executive of a  publicly-traded  company and are provided  information
          about the  company  that you have  reason to believe  has not yet been
          disclosed  in  a  widely-disseminated  publication  such  as  a  press
          release,  quarterly  report or other public filing,  you have received
          non-public information. This information is considered non-public even
          if you  believe  that the  company  executive  would  provide the same
          information  to other  analysts  or  portfolio  managers  who call the
          company.  Until  information has been disclosed in a manner that makes
          it  available  to (or  capable of being  accessed  by) the  investment
          community as a whole, it is considered non-public.  If the information
          is material, as described above, you may not trade while in possession
          of this  information  unless you first  discuss  the matter and obtain
          approval from the Director of Compliance, General Counsel or Associate
          General  Counsel.  Although  it may be lawful for an analyst to act on
          the basis of material  information  that the company's  management has
          chosen to disclose selectively to that analyst,  where the information
          is provided in a one-on-one context,


<PAGE>


          regulators are likely to question such conduct.  Approval from the Law
          and  Regulation  Department  will  therefore  depend  on the  specific
          circumstances of the information and the disclosure. Under the Supreme
          Court's  important  decision  of Dirks v. SEC,  463 U.S.  646  (1983),
          securities  analysts  may be  free  to act  on  selectively  disclosed
          material   information  if  it  is  provided  by  company   executives
          exclusively to achieve proper corporate purposes.

     b.   If you  obtain  material  information  in the  course of an  analysts'
          conference call or meeting conducted by a  publicly-traded  company in
          the  ordinary  course  of its  business  in which  representatives  of
          several  other firms or investors  are also present (as  distinguished
          from the one-on-one  situation described in the preceding  paragraph),
          you may act on the basis of that  information  without need to consult
          with the Director of Compliance,  General Counsel or Associate General
          Counsel,  even if the  information  has not yet been  published by the
          news media. You should be aware,  however,  that if there is something
          highly unusual about the meeting or conference  call that leads you to
          question whether it has been authorized by the company or is otherwise
          suspect,  you should first  consult  with the Director of  Compliance,
          General Counsel or Associate General Counsel.

     c.   If  you  are  provided  material  information  by a  company  and  are
          requested  to keep such  information  confidential,  you may not trade
          while in possession  of that  information  before first  obtaining the
          approval  of  the  Director  of  Compliance,  General  Counsel  or the
          Associate General Counsel.

     As these examples  illustrate,  the legal  requirements  governing  insider
trading are not always  obvious.  You should  therefore  always consult with the
Director of Compliance, General Counsel or Associate General Counsel if you have
any question at all about the appropriateness of your proposed conduct.

3.   Restricting Access To Material, Non-Public Information

     Information in your possession that you identify as material and non-public
     may not be  communicated  to anyone,  including  persons  within  Seligman,
     except as provided in paragraphs 1 and 2 above. In addition, care should be
     taken so that such  information is secure.  For example,  files  containing
     material, non-public information should be sealed; access to computer files
     containing material, non-public information should be restricted.

4.   Resolving Issues Concerning Insider Trading

     If, after consideration of the items set forth in paragraphs 1 and 2, doubt
     remains as to whether information is material or non-public, or if there is
     any unresolved  question as to the  applicability or  interpretation of the
     foregoing  procedures,  or as to the  propriety  of any action,  it must be
     discussed  with the  Director  of  Compliance,  General  Counsel and or the
     Associate  General Counsel before trading or communicating  the information
     to anyone.

5.   Personal Securities Trading

     All Employees shall follow with respect to personal  Securities trading the
     procedures set forth in the Code of Ethics. In addition,  no Employee shall
     establish  a  brokerage  Account  with a Firm other  than those  previously
     approved  without the prior consent of the Director of Compliance and every
     Employee shall be subject to reporting  requirements under Section III.5 of
     the Code of Ethics.  The Director of  Compliance,  or his  designee,  shall
     monitor the personal Securities trading of all Employees.
