The Fund

INVESTMENT OBJECTIVES


The Fund's investment objectives are high current income consistent with what is
believed to be prudent risk of capital and the possibility of improvement in
income and capital value over the longer term.


PRINCIPAL INVESTMENT STRATEGIES


The Fund uses the following principal investment strategies to seek its
investment objectives:


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

Subject to these requirements, the Fund may invest in many different types of
securities. Income-producing securities in which the Fund may invest include
money market instruments, fixed-income securities (such as notes, bonds,
debentures, and preferred stocks), 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
Fund's investment objectives and are diversified among many different types of
securities and market sectors.

The Fund allocates its assets between equity securities and fixed-income
securities. If equity valuations become excessive, then the Fund will invest
more of its assets in fixed-income securities. The Fund may also invest more of
its assets in fixed-income securities if the investment manager believes that
interest rates are at attractive levels.

Equity securities are chosen for purchase by the Fund using a bottom-up stock
selection approach. This means the investment manager concentrates on individual
company fundamentals, rather than on a particular industry. The Fund 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 Fund using a method that
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 Fund based on its evaluation of each security's particular
characteristics (for example, duration, yield, quality, relative value) and
total return opportunities.

The Fund 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
apply to ADRs or commercial paper and certificates of deposit issued by foreign
banks.

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


Except for its fundamental policy, the Fund may change its principal strategies
if the Fund's Board of Directors believes doing so is consistent with the Fund's
investment objectives. The Fund's objectives and its fundamental policy may be
changed only with shareholder approval.

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



                                       1
<PAGE>


PRINCIPAL RISKS

A significant portion of the Fund's assets are generally invested in common
stocks. Stock prices fluctuate. Therefore, as with any fund that invests in
stocks, the Fund'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.

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


Stocks of large US companies, like those in which the Fund 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 Fund's yield, net asset value, and total return.


The portion of the Fund'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 Fund. In general, the market value of fixed-income
securities move 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 Fund may affect the Fund's
net asset value. The extent to which the Fund is affected will depend on the
percentage of the Fund'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 Fund
holds securities that are downgraded, or default on payment, its performance
could be negatively affected.

Fixed-income securities, like those in which the Fund invests, are traded
principally by dealers in the over-the-counter market. The Fund'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 Fund may actively and frequently trade securities in its portfolio to carry
out its principal strategies. A high portfolio turnover rate increases
transaction costs which may increase the Fund's expenses.Frequent and active
trading may cause adverse tax consequences for investors in the Fund due to an
increase in short-term capital gains.


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

PAST PERFORMANCE


The Fund offers four Classes of shares. The information below provides some
indication of the risks of investing in the Fund by showing how the performance
of Class A shares has varied year to year, as well as how the performance of
each Class compares to three widely-used measures of performance.


The following performance information is designed to assist you in comparing the
returns of the Fund with the returns of other mutual funds. How the Fund has
performed in the past, however, is not necessarily an indication of how the Fund
will perform in the future. Total returns will vary between each Class of shares
due to the different fees and expenses of each Class.


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

FEES AND EXPENSES


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

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


                 1 Year       3 Years       5 Years       10 Years
                 ------       -------       -------       --------
Class A            $587         $823        $1,078        $1,806
Class B             693          897         1,226         2,027+
Class C             390          691         1,116         2,300
Class D             293          597         1,026         2,222


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


                 1 Year       3 Years       5 Years       10 Years
                 ------       -------       -------       --------
Class A           $587          $823        $1,078        $1,806

Shareholder Information

DECIDING WHICH CLASS OF SHARES TO BUY

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

     o    The amount you plan to invest.

     o    How long you intend to remain invested in the Fund, or another
          Seligman mutual fund.

     o    If you would prefer to pay an initial sales charge and lower ongoing
          12b-1 fees, or be subject to a CDSC and pay higher ongoing 12b-1 fees.

     o    Whether you may be eligible for reduced or no sales charges when you
          buy or sell shares.

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

          (2)  Your purchase of Class C shares must be for less than $1,000,000
               because if you invest $1,000,000 or more you will pay less in
               fees and charges if you buy Class A shares.

     o    A 1% CDSC on shares sold within eighteen months of purchase.

     o    Annual 12b-1 fee (for distribution and shareholder services) of 1.00%.

     o    No automatic conversion to Class Ashares, so you will be subject to
          higher ongoing 12b-1 fees indefinitely.


     o    No sales charge on reinvested dividends or capital gain distributions.


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

- --------------------------------------------------------------------------------
     Class D*

o    No initial sales charge on purchases.

o    A 1% CDSC on shares sold within one year of purchase.

o    Annual 12b-1 fee (for distribution and shareholder services) of 1.00%.

o    No automatic conversion to Class A shares, so you will be subject to higher
     ongoing 12b-1 fees indefinitely.

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


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


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


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


How CDSCs Are Calculated

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

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

PRICING OF FUND SHARES


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


- --------------------------------------------------------------------------------
NAV:

Computed separately for each Class by dividing that Class's share of the net
assets of the Fund (i.e., its assets less liabilities) by the total number of
outstanding shares of the Class.
- --------------------------------------------------------------------------------

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


The NAV of the Fund's shares is determined each day, Monday through Friday, on
days that the NYSE is open for trading. Because of their higher 12b-1 fees, the
NAV of Class B, Class C and Class D shares will generally be lower than the NAV
of Class A shares of the Fund.


Securities owned by the Fund 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.

OPENING YOUR ACCOUNT

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

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

The required minimum initial investments are:

     o    Regular (non-retirement) accounts: $1,000

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


- --------------------------------------------------------------------------------
You may buy shares of the Fund for all types of tax-deferred retirement plans.
Contact Retirement Plan Services at the address or phone number listed on the
inside back cover of this prospectus for information and to receive the proper
forms.
- --------------------------------------------------------------------------------

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

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

          If you want to be able to buy, sell, or exchange shares by
          telephone, you should complete an application when you open
          your account. This will prevent you from having to complete
          a supplemental election form (which may require a signature
          guarantee) at a later date.

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

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

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

Dividends From Other Investments. You may have your dividends from other
companies paid to the Fund. (Dividend checks must include your name, account
number, Fund name, and Class of shares.)

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

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


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


HOW TO EXCHANGE SHARES AMONG THE SELIGMAN MUTUAL FUNDS

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

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

If you exchange into a new fund, you must exchange enough to meet the new fund's
minimum initial investment.

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

HOW TO SELL SHARES

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

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

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


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


You may always send a written request to sell Fund shares; however, it may take
longer to get your money.

You will need to guarantee your signature(s) if the proceeds are:

     (1)  $50,000 or more;


     (2)  to be paid to someone other than the account owner; or


     (3)  mailed to other than your address of record.


- --------------------------------------------------------------------------------
Signature Guarantee: Protects you and the Fund from fraud. It guarantees that a
signature is genuine. A guarantee must be obtained from an eligible financial
institution. Notarization by a notary public is not an acceptable guarantee.
- --------------------------------------------------------------------------------


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

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

     o    a corporation;

     o    an executor or administrator;

     o    a trustee or custodian; or

     o    in a retirement plan.

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

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

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


Check Redemption Service. If you have at least $25,000 in the Fund, you may ask
SDC to provide checks which may be drawn against your account in amounts of $500
or more. You can elect this service on your initial application, or contact SDC
for the appropriate forms to establish this service. If you own Class A shares
that were bought at NAV because of the size of your purchase, or if you own
Class B shares, check redemptions may be subject to a CDSC. If you own Class D
or Class C shares, you may use this service only with respect to shares that you
have held for at least one year or eighteen months, respectively.

IMPORTANT POLICIES THAT MAY AFFECT YOUR ACCOUNT

To protect you and other shareholders, the Fund reserves the right to:

     o    Refuse an exchange request if:

          1.   you have exchanged twice from the same fund in any three-month
               period;

          2.   the amount you wish to exchange equals the lesser of $1,000,000
               or 1% of the Fund's net assets; or

          3.   you or your financial advisor have been advised that previous
               patterns of purchases and sales or exchanges have been considered
               excessive.

     o    Refuse any request to buy Fund shares;

     o    Reject any request received by telephone;

     o    Suspend or terminate telephone services;

     o    Reject a signature guarantee that SDC believes may be fraudulent;

     o    Close your fund account if its value falls below $500;

     o    Close your account if it does not have a certified taxpayer
          identification number.

Telephone Services

You and your broker/dealer or financial advisor will be able to place the
following requests by telephone, unless you indicate on your account application
that you do not want telephone services:

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

     o    Exchange shares between funds;

     o    Change dividend and/or capital gain distribution options;

     o    Change your address;

     o    Establish systematic withdrawals to address of record.

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

Restrictions apply to certain types of accounts:

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

     o    Corporations may not sell Fund shares by phone;

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

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

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

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

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

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

The Fund's NAV may fluctuate during this time. The Fund and SDC will not be
liable for processing requests received by phone as long as it was reasonable to
believe that the request was genuine.

Reinstatement Privilege

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

DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS

The Fund generally pays any dividends from its net investment income quarterly
and distributes any net capital gains realized on investments annually.


- --------------------------------------------------------------------------------
Dividend:

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

Capital Gain Distribution:

A payment to mutual fund shareholders which represents profits realized on the
sale of securities in a fund's portfolio.

Ex-dividend Date:

The day on which any declared distributions (dividends or capital gains) are
deducted from a fund's assets before it calculates its NAV.
- --------------------------------------------------------------------------------


You may elect to:

(1)  reinvest both dividends and capital gain distributions;

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

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

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

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

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

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

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

TAXES

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

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

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

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

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

                                  Fund History

The Fund was incorporated under the laws of the state of Maryland in 1947.

              Description of the Fund and its Investments and Risks

Classification

The Fund is a diversified open-end management investment company, or mutual
fund.

Investment Strategies and Risks

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

The Fund generally invests at least 65% of its total assets in income-producing
securities.


Convertible bonds. Convertible bonds are convertible at a stated exchange rate
or price into common stock. Before conversion, convertible securities are
similar to nonconvertible 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 nonconvertible debt securities 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 the Fund's 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
Fund may invest in debt securities convertible into equity securities rated as
low as CC by Standard & Poor's Ratings Service s (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 may 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, which tend to be more
speculative and riskier than higher rated debt securities, is set forth in
Appendix A to this document. 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 Fund's
investment objectives.


The Fund does not expect to invest more than 5% of its assets in nonconvertible
bonds, notes and debentures rated below investment grade (BB or lower by S&P or
Ba or lower by Moody's). Although bonds rated in the fourth credit rating
category (BBB or Baa) are commonly referred to as investment grade, they may
have speculative characteristics.

Collateralized Mortgage Obligations. The Fund 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 the
Government National Mortgage Association (GNMA), Federal National Mortgage
Association (FNMA) or Federal Home Loan


                                       2

<PAGE>


Mortgage Corporation (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 Fund 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.

Foreign Securities. The Fund may invest in commercial paper and certificates of
deposit issued by foreign banks and may invest either directly or through
American Depositary Receipts (ADRs), European Depositary Receipts (EDRs), or
Global Depositary Receipts (GDRs) (collectively, Depositary Receipts) in other
securities of foreign issuers. 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 and there may be delays and risks
attendant in local settlement procedures. 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 those in the
United States. Investments in foreign securities may also be subject to local
economic or political risks, political instability, the possible nationalization
of issuers and the risk of expropriation or restrictions on the repatriation of
proceeds of sale. In addition, foreign investments may be subject to withholding
and other taxes.

Depositary Receipts are instruments generally issued by domestic banks or trust
companies that represent the deposits of a security of a foreign issuer. 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. EDRs are typically traded in Europe. GDRs are typically traded in
both Europe and the United States. Depositary Receipts may be issued under
sponsored or unsponsored programs. In sponsored programs, the issuer has made
arrangements to have its securities traded in the form of a Depositary Receipt.
In unsponsored programs, the issuers may not be directly involved in the
creation of the program. Although regulatory requirements with respect to
sponsored and unsponsored Depositary Receipt programs are generally similar, the
issuers of securities represented by unsponsored Depositary Receipts are not
obligated to disclose material information in the United States, and therefore,
the import of such information may not be reflected in the market value of such
receipts. The Fund may invest up to 10% of its total assets in foreign
securities that it holds directly, but this 10% limit does not apply to foreign
securities held through Depositary Receipts which are traded in the United
States or to commercial paper and certificates of deposit issued by foreign
banks.

Investment income received by the Fund from sources within foreign countries may
be subject to foreign income taxes withheld at the source. The United States has
entered into tax treaties with many foreign countries which entitle the Fund to
a reduced rate of such taxes or exemption from taxes on such income. It is
impossible to determine the effective rate of foreign tax in advance since the
amounts of the Fund's assets to be invested within various countries is not
known.

Forward Foreign Currency Exchange Contracts. The investment manager will
consider changes in exchange rates in making investment decisions. As one way of
managing exchange rate risk, the Fund may enter into forward currency exchange
contracts. A forward foreign currency exchange contract is an agreement to
purchase or sell a specific currency at a future date and at a price set at the
time the contract is entered into. The Fund will


                                       3

<PAGE>


generally enter into these contracts to fix the US dollar value of a security
that it has agreed to buy or sell for the period between the date the trade was
entered into and the date the security is delivered and paid for.

The Fund may enter into a forward contract to sell or buy the amount of a
foreign currency it believes may experience a substantial movement against the
US dollar. In this case the contract would approximate the value of some or all
of the Fund's portfolio securities denominated in such foreign currency. Under
normal circumstances, the investment manager will limit forward currency
contracts to not greater than 75% of the Fund's portfolio position in any one
country as of the date the contract is entered into. This limitation will be
measured at the point the hedging transaction is entered into by the Fund. Under
extraordinary circumstances, the investment manager may enter into forward
currency contracts in excess of 75% of the Fund's portfolio position in any one
country as of the date the contract is entered into. The precise matching of the
forward contract amounts and the value of securities involved will not generally
be possible since the future value of such securities in foreign currencies will
change as a consequence of market involvement in the value of those securities
between the date the forward contract is entered into and the date it matures.
The projection of short-term currency market movement is extremely difficult,
and the successful execution of a short-term hedging strategy is highly
uncertain. Under certain circumstances, the Fund may commit up to the entire
value of its assets which are denominated in foreign currencies to the
consummation of these contracts. The investment manager will consider the effect
a substantial commitment of its assets to forward contracts would have on the
investment program of the Fund and its ability to purchase additional
securities.

Except as set forth above and immediately below, the Fund will also not enter
into such forward contracts or maintain a net exposure to such contracts where
the consummation of the contracts would oblige the Fund to deliver an amount of
foreign currency in excess of the value of the Fund's portfolio securities or
other assets denominated in that currency. The Fund, in order to avoid excess
transactions and transaction costs, may nonetheless maintain a net exposure to
forward contracts in excess of the value of the Fund's portfolio securities or
other assets denominated in that currency provided the excess amount is
"covered" by cash or liquid, high-grade debt securities, denominated in any
currency, having a value at least equal at all times to the amount of such
excess. Under normal circumstances, consideration of the prospect for currency
parities will be incorporated into the longer term investment decisions made
with regard to overall diversification strategies. However, the investment
manager believes that it is important to have the flexibility to enter into such
forward contracts when it determines that the best interests of the Fund will be
served.

At the maturity of a forward contract, the Fund may either sell the portfolio
security and make delivery of the foreign currency, or it may retain the
security and terminate its contractual obligation to deliver the foreign
currency by purchasing an "offsetting" contract obligating it to purchase, on
the same maturity date, the same amount of the foreign currency.

As indicated above, it is impossible to forecast with absolute precision the
market value of portfolio securities at the expiration of the forward contract.
Accordingly, it may be necessary for the Fund to purchase additional foreign
currency on the spot market (and bear the expense of such purchase) if the
market value of the security is less than the amount of foreign currency the
Fund is obligated to deliver and if a decision is made to sell the security and
make delivery of the foreign currency. Conversely, it may be necessary to sell
on the spot market some of the foreign currency received upon the sale of the
portfolio security if its market value exceeds the amount of foreign currency
the Fund is obligated to deliver. However, the Fund may use liquid, high-grade
debt securities, denominated in any currency, to cover the amount by which the
value of a forward contract exceeds the value of the securities to which it
relates.

If the Fund retains the portfolio security and engages in an offsetting
transaction, the Fund will incur a gain or a loss (as described below) to the
extent that there has been movement in forward contract prices. If the Fund
engages in an offsetting transaction, it may subsequently enter into a new
forward contract to sell the foreign currency. Should forward prices decline
during the period between the Fund's entering into a forward contract for the
sale of a foreign currency and the date it enters into an offsetting contract
for the purchase of the foreign currency, the Fund will realize a gain to the
extent the price of the currency it has agreed to sell exceeds the price of the
currency it has agreed to purchase. Should forward prices increase, the Fund
will suffer a loss to the extent the price of the currency it has agreed to
purchase exceeds the price of the currency it has agreed to sell.


                                       4

The Fund's dealing in forward foreign currency exchange contracts will be
limited to the transactions described above. Of course, the Fund is not required
to enter into forward contracts with regard to its foreign currency-denominated
securities and will not do so unless deemed appropriate by the investment
manager.

Although the Fund will seek to benefit by using forward contracts, anticipated
currency movements may not be accurately predicted and the Fund may therefore
incur a gain or loss on a forward contract. A forward contract may help reduce
the Fund's losses on securities denominated in a hedged currency, but it may
also reduce the potential gain on the securities which might result from an
increase in the value of that currency.

Investors should be aware of the costs of currency conversion. Although foreign
exchange dealers do not charge a fee for conversion, they do realize a profit or
"spread" based on the difference between the prices at which they are buying and
selling various currencies. Thus, a dealer may offer to sell a foreign currency
to the Fund at one rate, while offering a lesser rate of exchange should the
Fund desire to resell that currency to the dealer.

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

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, a decline in value of the
underlying securities and a loss of interest. Repurchase agreements are
typically entered into for periods of one week or less. As a matter of
fundamental policy, the Fund will not enter into repurchase agreements of more
than one week's duration if more than 10% of its net assets would be so
invested.

Illiquid Securities. The Fund may invest up to 15% of its net assets in illiquid
securities, including restricted securities (i.e., securities not readily
marketable without registration under the Securities Act of 1933 (1933 Act)) and
other securities that are not readily marketable. The Fund 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 the Fund, if and to the extent that
qualified institutional buyers become for a time uninterested in purchasing Rule
144A securities.

Borrowing. The Fund may borrow money for temporary or emergency purposes in an
amount not to exceed 15% of the value of its total assets. The Fund may pledge
its assets only to the extent necessary to effect permitted borrowings on a
secured basis.

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

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

Lending of Portfolio Securities. The Fund may lend portfolio securities to
broker/dealers or other institutions, if the investment manager believes such
loans will be beneficial to the Fund. The borrower must maintain with the Fund
cash or equivalent collateral equal to at least 100% of the market value of the
securities loaned. During the


                                       5

<PAGE>


time portfolio securities are on loan, the borrower pays the Fund any dividends
or interest paid on the securities. The Fund may invest the collateral and earn
additional income or receive an agreed upon amount of interest income from the
borrower. Loans made by the Fund will generally be short-term. Loans are subject
to termination at the option of the Fund or the borrower. The Fund may pay
reasonable administrative and custodial fees in connection with a loan and may
pay a negotiated portion of the interest earned on the collateral to the
borrower or placing broker. The Fund does not have the right to vote securities
on loan, but would terminate the loan and regain the right to vote if that were
considered important with respect to the investment. The Fund may lose money if
a borrower defaults on its obligation to return securities and the value of the
collateral held by the Fund is insufficient to replace the loaned securities. In
addition, the Fund is responsible for any loss that might result from its
investment of the borrower's collateral.

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

Fund Policies

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

- -    Borrow money, except for temporary or emergency purposes in an amount not
     to exceed 15% of the value of its total assets;

- -    Mortgage or pledge any of its assets, except to the extent necessary to
     effect permitted borrowings on a secured basis and except to enter into
     escrow arrangements in connection with the sales of permitted call options.
     The Fund has no present intention of selling call options, and will not do
     so without the prior approval of the Fund's Board of Directors;

- -    Purchase securities (other than closing call options) except for
     investment, buy on "margin," or sell "short";

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

- -    Invest more than 5% of its total assets (taken at market) in securities of
     any one issuer, other than the US Government, its agencies or
     instrumentalities, buy more than 10% of the outstanding voting securities
     or more than 10% of all the securities of any issuer, or invest to control
     or manage any company;

- -    Invest more than 25% of total assets at market value in any one industry;


- -    Invest in securities issued by other investment companies, except in
     connection with a merger, consolidation, acquisition or reorganization or
     for the purpose of hedging the Fund's obligations under its deferred
     compensation plan for directors;


- -    Purchase or hold any real estate, including limited partnership interests
     in real property, except the Fund may invest in securities secured by real
     estate or interests therein or issued by persons (including real estate
     investment trusts) which deal in real estate or interests therein;

- -    Purchase or hold the securities of any issuer, if to its knowledge,
     directors or officers of the Fund individually owning beneficially more
     than 0.5% of the securities of that other company own in the aggregate more
     than 5% of such securities;

- -    Deal with its directors or officers, or firms they are associated with, in
     the purchase or sale of securities of other issuers, except as broker;

- -    Purchase or sell commodities and commodity contracts;


                                       6

<PAGE>



- -    Underwrite the securities of other issuers, except insofar as the Fund may
     be deemed an underwriter under the 1933 Act in disposing of a portfolio
     security;


- -    Make loans, except loans of portfolio securities and except to the extent
     the purchase of notes, bonds or other evidences of indebtedness, the entry
     into repurchase agreements or deposits with banks may be considered loans;
     or

- -    Write or purchase put, call, straddle or spread options except that the
     Fund may sell covered call options listed on a national securities exchange
     or quoted on NASDAQ and purchase closing call options so listed or quoted.
     The Fund has no present intention of entering into these types of
     transactions, and will not do so without the prior approval of the Fund's
     Board of Directors.

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

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

Temporary Defensive Position

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

Portfolio Turnover


The Fund's portfolio turnover rate is 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 Fund's portfolio turnover rates for the years
ended December 31, 1999 and 1998 were 72.46% and 124.79%%, respectively.

- ----------

(1)  For the Fund's year ended December 31, 1999. Effective January 21, 2000,
     the per meeting fee for Directors was increased by $1,000, which is
     allocated among all Funds in the Fund Complex.

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

(3)  Deferred.

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
directors' fees and expenses, and the accumulated balance thereof is included in
other liabilities in the Fund's financial statements. The total amount of
deferred compensation (including earnings) payable in respect of the Fund to Mr.
Whitson as of December 31, 1999 was $19,616.

Messrs. Merow and Pitney no longer defer current compensation; however, they
have accrued deferred compensation (including earnings) in the amounts of
$61,517 and $28,670, 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.

Sales Charges

Class A shares of the Fund may be issued without a sales charge to present and
retired directors, trustees, officers, employees (and their family members) of
the Fund, the other investment companies in the Seligman Group, and Seligman and
its affiliates. Family members are defined to include lineal descendants and
lineal ancestors, siblings (and their spouses and children) and any company or
organization controlled by any of the foregoing. Such sales may also be made to
employee benefit plans and thrift plans for such persons and to any investment
advisory, custodial, trust or other fiduciary account managed or advised by
Seligman or any affiliate. The sales may be made for investment purposes only,
and shares may be resold only to the Fund.


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

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, or knows of
another's intention, to purchase or sell a 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.

The Management Agreement provides that Seligman 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 its duties under the
Agreement, except for willful misfeasance, bad faith, gross negligence, or
reckless disregard of its obligations and duties under the Agreement.

The Management Agreement was initially approved by the Board of Directors at a
Meeting held on September 30, 1988 and by the shareholders at a special meeting
held on December 16, 1988. Amendments to the Management Agreement, effective

at a special meeting held on April 10, 1991. The amendments to the Management
Agreement, effective January 1, 1996 to increase the fee rate payable to
Seligman by the Fund were approved by the Board of Directors on September 21,
1995 and by the shareholders at a special meeting held on December 12, 1995. The
Management Agreement will continue in effect until December 31 of each year if
(1) such continuance is approved in the manner required by the 1940 Act (i.e.,
by a vote of a majority of the Board of Directors or of the outstanding voting
securities of the Fund and by a vote of a majority of the Directors who are not
parties to the Management Agreement or interested persons of any such party) and
(2) Seligman shall not have notified the Fund at least 60 days prior to December
31 of any year that it does not desire such continuance. The Management
Agreement may be terminated by the Fund, without penalty, on 60 days' written
notice to Seligman and will terminate automatically in the event of its
assignment. The Fund has agreed to change its name upon termination of the
Management Agreement if continued use of the name would cause confusion in the
context of Seligman's business.

Rule 12b-1 Plan

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

Under the 12b-1 Plan, the Fund may pay to Seligman Advisors an administration,
shareholder services and distribution fee in respect of the Fund's Class A,
Class B, Class C, and Class D shares. Payments under the 12b-1 Plan may include,
but are not limited to: (1) compensation to securities dealers and other
organizations (Service Organizations) for providing distribution assistance with
respect to assets invested in the Fund; (2) compensation to Service
Organizations for providing administration, accounting and other shareholder
services with respect to Fund shareholders; and (3) otherwise promoting the sale
of shares of the Fund, including paying for the preparation of advertising and
sales literature and the printing and distribution of such promotional materials
and prospectuses to prospective investors and defraying Seligman Advisors' costs
incurred in connection with its marketing efforts with respect to shares of the
Fund. Seligman, in its sole discretion, may also make similar payments to
Seligman Advisors from its own resources, which may include the management fee
that Seligman receives from the Fund. Payments made by the Fund under the 12b-1
Plan are intended to be used to encourage sales of the Fund, as well as to
discourage redemptions.

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

Class A


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



                                       15

<PAGE>



Advisors in respect of Class A shares for the year ended December 31, 1999 was
$572,874, equivalent to .25% per annum of the Class A shares' average daily net
assets.


Class B


Under the 12b-1 Plan, the Fund, with respect to Class B shares, pays monthly a
12b-1 fee at an annual rate of up to 1% of the average daily net asset value of
the Class B shares. This fee is comprised of (1) a distribution fee equal to
 .75% per annum, which is paid directly to a third party, FEP Capital, L.P., to
compensate it for having funded, at the time of sale of Fund shares (i) a 4%
commission payment to Service Organizations in connection with the sale of the
Class B shares and (ii) a payment of up to .25% of sales to Seligman Advisors to
help defray its costs of distributing Class B shares; and (2) a service fee of
up to .25% per annum which is paid to Seligman Advisors. The service fee is used
by Seligman Advisors exclusively to make payments to Service Organizations which
have entered into agreements with Seligman Advisors. Such Service Organizations
receive from Seligman Advisors a continuing service fee of up to .25% on an
annual basis, payable quarterly, of the average daily net assets of Class B
shares attributable to the particular Service Organization for providing
personal service and/or maintenance of shareholder accounts. The amounts
expended by Seligman Advisors or FEP Capital, L.P. in any one year upon the
initial purchase of Class B shares of the Fund may exceed the 12b-1 fees paid by
the Fund in that year. The Fund's 12b-1 Plan permits expenses incurred in
respect of Class B shares in one year to be paid from Class B 12b-1 fees
received from the Fund in any other year; however, in any fiscal year the Fund
is not obligated to pay any 12b-1 fees in excess of the fees described above.
Seligman Advisors and FEP Capital, L.P. are not reimbursed for expenses which
exceed such fees. If the Fund's 12b-1 Plan is terminated in respect of Class B
shares, no amounts (other than amounts accrued but not yet paid) would be owed
by that Fund to Seligman Advisors or FEP Capital, L.P. with respect to Class B
shares. The total amount paid by the Fund in respect of Class B shares for the
year ended December 31, 1999 was $219,064, equivalent to 1% per annum of the
Class B shares' average daily net assets.


Class C


Under the 12b-1 Plan, the Fund, with respect to Class C shares, pays monthly to
Seligman Advisors a 12b-1 fee at an annual rate of up to 1% of the average daily
net asset value of the Class C shares. This fee is used by Seligman Advisors as
follows: During the first year following the sale of Class C shares, a
distribution fee of .75% of the average daily net assets attributable to Class C
shares is used, along with any CDSC proceeds during the first eighteen months,
to (1) reimburse Seligman Advisors for its payment at the time of sale of Class
C shares of a 1.25% sales commission to Service Organizations, and (2) pay for
other distribution expenses, including paying for the preparation of advertising
and sales literature and the printing and distribution of such promotional
materials and prospectuses to prospective investors and other marketing costs of
Seligman Advisors. In addition, during the first year following the sale of
Class C shares, a service fee of up to .25% of the average daily net assets
attributable to such Class C shares is used to reimburse Seligman Advisors for
its prepayment to Service Organizations at the time of sale of Class C shares of
a service fee of .25% of the net asset value of the Class C share sold (for
shareholder services to be provided to Class C shareholders over the course of
the one year immediately following the sale). The payment of service fees to
Seligman Advisors is limited to amounts Seligman Advisors actually paid to
Service Organizations at the time of sale as service fees. After the initial
one-year period following a sale of Class C shares, the entire 12b-1 fee
attributable to such Class C shares is paid to Service Organizations for
providing continuing shareholder services and distribution assistance in respect
of the Fund. The total amount paid by the Fund to Seligman Advisors in respect
of Class C shares for the year ended December 31, 1999 was $4,927, equivalent to
1% per annum of the Class C shares' average daily net assets.

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

As of December 31, 1999, Seligman Advisors incurred $34,055 of unreimbursed
expenses in respect of the Fund's Class C shares. This amount is equal to 2.03%
of the net assets of Class C shares at December 31, 1999.

If the Fund's 12b-1 Plan is terminated in respect of Class C shares of the Fund,
no amounts (other than amounts accrued but not yet paid) would be owed by the
Fund to Seligman Advisors with respect to Class C shares.

Class D


Under the 12b-1 Plan, the Fund, with respect to Class D shares, pays monthly to
Seligman Advisors a 12b-1 fee at an annual rate of up to 1% of the average daily
net asset value of the Class D shares. This fee is used by Seligman Advisors as
follows: During the first year following the sale of Class D shares, a
distribution fee of .75% of the average daily net assets attributable to such
Class D shares is used, along with any CDSC proceeds, to (1) reimburse Seligman
Advisors for its payment at the time of sale of Class D shares of a .75% sales
commission to Service Organizations, and (2) pay for other distribution
expenses, including paying for the preparation of advertising and sales
literature and the printing and distribution of such promotional materials and
prospectuses to prospective investors and other marketing costs of Seligman
Advisors. In addition, during the first year following the sale of Class D
shares, a service fee of up to .25% of the average daily net assets attributable
to such Class D shares is used to reimburse Seligman Advisors for its prepayment
to Service Organizations at the time of sale of Class D shares of a service fee
of .25% of the net asset value of the Class D shares sold (for shareholder
services to be provided to Class D shareholders over the course of the one year
immediately following the sale). The payment of service fees to Seligman
Advisors is limited to amounts Seligman Advisors actually paid to Service
Organizations at the time of sale as service fees. After the initial one-year
period following a sale of Class D shares, the entire 12b-1 fee attributable to
such Class D shares is paid to Service Organizations for providing continuing
shareholder services and distribution assistance in respect of the Fund. The
total amount paid by the Fund to Seligman Advisors in respect of Class D shares
for the year ended December 31, 1999 was $679,448, equivalent to 1% per annum of
the Class D shares' average daily net .


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


As of December 31, 1999, Seligman Advisors incurred $177,690 of unreimbursed
expenses in respect of the Fund's Class D shares. This amount is equal to .33%
of the net assets of Class D shares at December 31, 1999.


If the Fund's 12b-1 Plan is terminated in respect of Class D shares of the Fund,
no amounts (other than amounts accrued but not yet paid) would be owed by the
Fund to Seligman Advisors with respect to Class D shares.


Payments made by the Fund under the 12b-1 Plan for its year ended December 31,
1999, were spent on the following activities in the following amounts:

                                   Class A     Class B*    Class C**    Class D

**   From May 27, 1999 (inception) to December 31, 1999.

The 12b-1 Plan was approved on July 16, 1992 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 have no direct or indirect
financial interest in the operation of the 12b-1 Plan or in any agreement
related to the 12b-1 Plan ( "Qualified Directors) and was approved by
shareholders of the Fund at a Special Meeting of the Shareholders held on
November 23, 1992. The 12b-1 Plan became effective in respect of the Class A
shares on January 1, 1993. The 12b-1 Plan was approved in respect of the Class B
shares on March 21, 1996 by the Board of Directors of the Fund, including a
majority of the Qualified Directors, and became effective in respect of the
Class B shares on April 22, 1996. The 12b-1 Plan was approved in respect of the
Class C shares on May 20, 1999 by the Board of Directors, including a majority
of the Qualified Directors, and became effective in respect of the Class C
shares on June 1, 1999. The 12b-1 Plan was approved in respect of the Class D
shares on March 18, 1993 by the Board of Directors, including a majority of the
Qualified Directors, and became effective in respect of the Class D shares on
May 1, 1993. 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 of the Fund and the Qualified Directors, cast in person at a
meeting called for the purpose of voting on such approval. The 12b-1 Plan may
not



                                       17

<PAGE>



be amended to increase materially the amounts payable to Service Organizations
with respect to a class without the approval of a majority of the outstanding
voting securities of the class. If the amount payable in respect of Class A
shares under the 12b-1 Plan is proposed to be increased materially, the Fund
will either (1) permit holders of Class B shares to vote as a separate class on
the proposed increase or (2) establish a new class of shares subject to the same
payment under the 12b-1 Plan as existing Class A shares, in which case the Class
B shares will thereafter convert into the new class instead of into Class A
shares. No material amendment to the 12b-1 Plan may be made except by vote of a
majority of both the Directors and the Qualified Directors.


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


Seligman Services acts as a broker/dealer of record for shareholder accounts
that do not have a designated financial advisor and receives compensation
pursuant to the Fund's 12b-1 Plan for providing personal services and account
maintenance to such accounts and other distribution services. For the years
ended December 31, 1999, 1998 and 1997, Seligman Services received distribution
and service fees pursuant to the Fund's 12b-1 Plan of $46,574, $50,371 and
$51,665, respectively.


                    Brokerage Allocation and Other Practices

Brokerage Transactions

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

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


For the years ended December 31, 1999, 1998 and 1997, the Fund paid total
brokerage commissions to others for execution, research and statistical services
in the amounts of $192,862, $677,449 and $298,513 , respectively. The amount of
brokerage commissions paid by the Fund were materially higher from 1997 to 1998
due to both a realignment of the Fund, which decreased its convertible debt
holdings and increased its equity holdings, and the Fund's sale of international
securities.


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, or Seligman Advisors.


Brokerage Selection

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


                                       18

although such research and analysis may be useful to Seligman in connection with
its services to clients other than the Fund.

Directed Brokerage


During the year ended December 31, 1999, neither the Fund nor Seligman, 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 year ended December 31, 1999, the Fund did not acquire securities 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 500,000,000 shares of capital stock, each with a
par value of $1.00, divided into four classes, designated Class A common stock,
Class B common stock, Class C common stock and Class D common stock. Each share
of the Fund's Class A, Class B, Class C and Class D common stock is equal as to
earnings, assets, and voting privileges, except that each class bears its own
separate distribution and, potentially, certain other class expenses and has
exclusive voting rights with respect to any matter to which a separate vote of
any class is required by the 1940 Act or Maryland law. The Fund has adopted a
multiclass plan pursuant to Rule 18f-3 under the 1940 Act permitting the
issuance and sale of multiple classes of common stock. In accordance with the
Articles of Incorporation, the Board of Directors may authorize the creation of
additional classes of common stock with such characteristics as are permitted by
the multiclass plan and Rule 18f-3. The 1940 Act requires that where more than
one class exists, each class must be preferred over all other classes in respect
of assets specifically allocated to such class. All shares have noncumulative
voting rights for the election of directors. Each outstanding share is fully
paid and non-assessable, and each is freely transferable. There are no
liquidation, conversion, or preemptive rights.

Other Securities

The Fund has no authorized securities other than common stock.

                   Purchase, Redemption, and Pricing of Shares

Purchase of Shares

Class A

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

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

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

The Right of Accumulation allows an investor to combine the amount being
invested in Class A shares of the Fund and shares of the other Seligman mutual
funds sold with an initial sales charge with the total net asset value of shares
of those mutual funds already owned that were sold with an initial sales charge
and the total net asset value of shares of Seligman Cash Management Fund which
were acquired through an exchange of shares of another Seligman mutual fund on
which there was an initial sales charge at the time of purchase to determine


                                       19

<PAGE>


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

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

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

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

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

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

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

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

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

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


                                       20

<PAGE>


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

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

(4)  to financial institution trust departments;

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

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

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

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

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

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

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

CDSC Applicable to Class A Shares. Class A shares purchased without an initial
sales charge due to a purchase of $1,000,000 or more either alone or through a
Volume Discount, Right of Accumulation, or Letter of Intent are subject to a
CDSC of 1% on redemptions of such shares within eighteen months of purchase.
Employee benefit plans eligible for net asset value sales may be subject to a
CDSC of 1% for terminations at the plan level only, on redemptions of shares
purchased within eighteen months prior to plan termination. The 1% CDSC will be
waived on shares that were purchased through Morgan Stanley Dean Witter & Co. by
certain Chilean institutional investors (i.e., pension plans, insurance
companies, and mutual funds). Upon redemption of such shares within an
eighteen-month period, Morgan Stanley Dean Witter will reimburse Seligman
Advisors a pro rata portion of the fee it received from Seligman Advisors at the
time of sale of such shares.

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

Class B

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

Years Since Purchase                                         CDSC
- --------------------                                         ----
Less than 1 year ..........................................   5%
1 year or more but less than 2 years ......................   4%
2 years or more but less than 3 years .....................   3%
3 years or more but less than 4 years .....................   3%
4 years or more but less than 5 years .....................   2%
5 years or more but less than 6 years .....................   1%
6 years or more ...........................................   0%


                                       21

<PAGE>


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

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

Class C

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

Class D

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

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

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

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

(2)  in connection with (1) distributions from retirement plans qualified under
     Section 401(a) of the Internal Revenue Code when such redemptions are
     necessary to make distributions to plan participants (such payments
     include, but are not limited to, death, disability, retirement, or
     separation of service), (2) distributions from a custodial account under
     Section 403(b)(7) of the Internal Revenue Code or an IRA due to death,
     disability, minimum distribution requirements after attainment of age 70
     1/2 or, for accounts established prior to January 1, 1998, attainment of
     age 59 1/2, and (3) a tax-free return of an excess contribution to an IRA;

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

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

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

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


                                       22

<PAGE>


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

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

Fund Reorganizations

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

Offering Price

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

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

Portfolio securities are valued at the last sales price on the securities
exchange or securities market on which such securities primarily are traded.
Securities not listed on an exchange or securities market, or securities in
which there were no transactions, are valued at the average of the most recent
bid and asked price, except in the case of open short positions where the asked
price is available. Securities traded on a foreign exchange or over-the-counter
market are valued at the last sales price on the primary exchange or market on
which they are traded. United Kingdom securities and securities for which there
are no recent sales transactions are valued based on quotations provided by
primary market makers in such securities. Any securities or other assets for
which recent market quotations are not readily available are valued at fair
value as determined in accordance with procedures approved by the Board of
Directors. Short-term obligations with less than 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 determines that this
amortized cost value does not represent fair market value. Expenses and fees,
including the investment management fee, are accrued daily and taken into
account for the purpose of determining the net asset value of Fund shares.


                                       23

<PAGE>


Generally, trading in foreign securities, as well as US Government securities,
money market instruments and repurchase agreements, is substantially completed
each day at various times prior to the close of the NYSE. The values of such
securities used in computing the net asset value of the shares of the Fund are
determined as of such times. Foreign currency exchange rates are also generally
determined prior to the close of the NYSE.

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

Specimen Price Make-Up


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

Class A
     Net asset value per share ....................................       $13.57

     Maximum sales charge (4.75% of offering price) ...............          .68
                                                                          ------

     Offering price to public .....................................       $14.25
                                                                          ======

Class B
     Net asset value and offering price per share(2) ..............       $13.52
                                                                          ======

     Offering price to public .....................................       $13.66
                                                                          ======

Class D
     Net asset value and offering price per share(2) ..............       $13.52
                                                                          ======
- ----------
(1)  In addition to the front-end sales charge of 1.00%, Class C shares are
     subject to a 1% CDSC if you redeem your shares within 18 months of
     purchase.

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


Redemption in Kind


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


                              Taxation of the Fund

The Fund is qualified and intends to continue to qualify as a regulated
investment company under Subchapter M of the Internal Revenue Code. For each
year so qualified, the Fund will not be subject to federal income taxes on its
net investment income and capital gains, if any, realized during any taxable
year, which it distributes to its shareholders, provided that at least 90% of
its net investment income and net short-term capital gains are distributed to
shareholders each year.


                                       24

<PAGE>


Dividends from net investment income and distributions from net short-term
capital gains are taxable as ordinary income to shareholders, whether received
in cash or reinvested in additional shares. To the extent designated as derived
from the Fund's dividend income that would be eligible for the dividends
received deduction if the Fund were not a regulated investment company, they are
eligible, subject to certain restrictions, for the 70% dividends received
deduction for corporations.

Distributions of net capital gains (i.e., the excess of net long-term capital
gains over any net short-term losses) are taxable as long-term capital gain,
whether received in cash or invested in additional shares, regardless of how
long the shares have been held by a shareholder. Such distributions are not
eligible for the dividends received deduction allowed to corporate shareholders.
Shareholders receiving distributions in the form of additional shares issued by
the Fund will be treated for federal income tax purposes as having received a
distribution in an amount equal to the fair market value on the date of
distribution of the shares received. Individual shareholders generally will be
subject to federal tax on distributions of net capital gains at a maximum rate
of 20% if designated as derived from the Fund's capital gains from property held
for more than one year.

Any gain or loss realized upon a sale or redemption of shares in the Fund by a
shareholder who is not a dealer in securities will generally be treated as a
long-term capital gain or loss if the shares have been held for more than one
year and otherwise as a short-term capital gain or loss. Individual shareholders
will be subject to federal income tax on net capital gains at a maximum rate of
20% in respect of shares held for more than one year. Net capital gain of a
corporate shareholder is taxed at the same rate as ordinary income. However, if
shares on which a long-term capital gain distribution has been received are
subsequently sold or redeemed and such shares have been held for six months or
less, any loss realized will be treated as a long-term capital loss to the
extent that it offsets the long-term capital gain distribution. In addition, no
loss will be allowed on the sale or other disposition of shares of the Fund if,
within a period beginning 30 days before the date of such sale or disposition
and ending 30 days after such date, the holder acquires (including shares
acquired through dividend reinvestment) securities that are substantially
identical to the shares of the Fund.

In determining gain or loss on shares of the Fund that are sold or exchanged
within 90 days after acquisition, a shareholder generally will not be permitted
to include in the tax basis attributable to such shares the sales charge
incurred in acquiring such shares to the extent of any subsequent reduction of
the sales charge by reason of the Exchange or Reinstatement Privilege offered by
the Fund. Any sales charge not taken into account in determining the tax basis
of shares sold or exchanged within 90 days after acquisition will be added to
the shareholder's tax basis in the shares acquired pursuant to the Exchange or
Reinstatement Privilege.

The Fund will generally be subject to an excise tax of 4% on the amount of any
income or capital gains, above certain permitted levels, distributed to
shareholders on the basis such that such income or gain is not taxable to
shareholders in the calendar year in which it was earned by the Fund.
Furthermore, dividends declared in October, November or December, payable to
shareholders of record on a specified date in such a month and paid in the
following January will be treated as having been paid by the Fund and received
by each shareholder in December. Under this rule, therefore, shareholders may be
taxed in one year on dividends or distributions actually received in January of
the following year.

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

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

Distribution of Securities

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

Total initial sales charges paid by shareholders of Class A shares of the Fund
for the years ended December 31, 1999, 1998 and 1997 amounted to $124,745,

(1)  Seligman Advisors has sold its rights to collect the distribution fees paid
     by the Fund in respect of Class B shares and any CDSC imposed on
     redemptions of Class B shares to FEP Capital, L.P., in connection with an
     arrangement with FEP Capital, L.P. as discussed above under "12b-1 Plan."
     In connection with this arrangement, Seligman Advisors receives payments
     from FEP Capital, L.P. based on the value of Class B shares sold. Such
     payments received for the year ended December 31, 1999 are reflected in the
     table.


Other Payments

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

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


                                       26

<PAGE>


of sales from $2 million up to but not including $3 million; .50% of sales from
$3 million up to but not including $5 million; and .25% of sales from $5 million
and above.


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


                         Calculation of Performance Data


Class A

The average annual total returns for the Fund's Class A shares for the one-,
five-, and ten-year periods December 31, 1999, were (6.46)%, 8.36% and 8.68%,
respectively. These returns were computed by subtracting the maximum sales
charge of 4.75% of public offering price and assuming that all of the dividends
and capital gain distributions paid by the Fund over the relevant time period
were reinvested. It was then assumed that at the end of each period, the entire
amount was redeemed. The average annual total return was then calculated by
calculating the annual rate required for the initial payment to grow to the
amount which would have been received upon such redemption (i.e., the average
annual compound rate of return). Table A below illustrates the total return
(income and capital) on Class A shares of the Fund, assuming all dividend and
capital gain distributions are reinvested in additional shares. It shows that a
$1,000 investment in Class A shares made on December 31, 1989 had a value of
$2,2982,693 on December 31, 1999, resulting in an aggregate total return of
129.82%.

Class B

The average annual total returns for the Fund's Class B shares for the one-year
period ended December 31, 1999 and for the period from April 22, 1996
(inception) through December 31, 1999, were (7.20)% and 5.88%, respectively.
These returns were computed assuming that all of the dividends and capital gain
distributions paid by the Fund's Class B shares, if any, were reinvested over
the relevant time period. It was then assumed that at the end of each period,
the entire amount was redeemed, subtracting the applicable CDSC. Table B
illustrates the total return (income and capital) on Class B shares of the Fund,
assuming all dividends and capital gain distributions are reinvested in
additional shares. It shows that a $1,000 investment in Class B shares on April
22, 1996 (commencement of operations of Class B shares) had a value of $1,235 on
December 31, 1999, resulting in an aggregate total return of 23.49%.

Class C

The total return for the Fund's Class C shares for the period from May 27, 1999
(inception) through December 31, 1999, was (4.04)%. This return was computed
assuming that all of the dividends and capital gain distributions paid by the
Fund's Class C shares, if any, were reinvested over the period. It was then
assumed that at the end of the period, the entire amount was redeemed,
subtracting the 1% CDSC, if applicable. Table C illustrates the total return
(income and capital) on Class C shares of the Fund, assuming all dividends and
capital gain distributions are reinvested in additional shares. It shows that a
$1,000 investment in Class C shares made on May 27, 1999 (commencement of
operations of Class C shares) had a value of $960 on December 31, 1999,
resulting in an aggregate total return of (4.04)%.



                                       27

<PAGE>



Class D

The average annual total returns for the Fund's Class D shares for the one- and
five-year periods ended December 31, 1999 and for the period from May 3, 1993
(inception) through December 31, 1999, were (3.42)%, 8.58% and 6.58%,
respectively. These returns were computed assuming that all of the dividends and
capital gain distributions paid by the Fund's Class D shares, if any, were
reinvested over the relevant time period. It was then assumed that at the end of
each period, the entire amount was redeemed, subtracting the 1% CDSC, if
applicable. Table D illustrates the total return (income and capital) on Class D
shares of the Fund, assuming all dividends and capital gain distributions are
reinvested in additional shares. It shows that a $1,000 investment in Class D
shares made on May 3, 1993 (commencement of operations of Class D shares) had a
value of $1,529 on December 31, 1999, resulting in an aggregate total return of
52.90%.

The results shown below should not be considered a representation of the
dividend income or gain or loss in capital value which may be realized from an
investment made in a class of shares of the Fund today.

(1)  For the ten-year period ended December 31, 1998 for Class A shares, from
     commencement of operations of Class B shares on April 22, 1996, from
     commencement of operations of Class C shares on May 27, 1999 and from
     commencement of operations of Class D shares on May 3, 1993.

(2)  The "Value of Initial Investment" as of the date indicated (1) reflects the
     effect of the maximum initial sales charge or CDSC, if applicable, (2)
     assumes that all dividends and capital gain distributions were taken in
     cash, and (3) reflects changes in the net asset value of the shares
     purchased with the hypothetical initial investment. "Total Value of
     Investment" (1) reflects the effect of the CDSC, if applicable, and (2)
     assumes investment of all dividends and capital gain distributions.

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


The total returns and average annual total returns of Class A shares quoted from
time to time for periods through December 31, 1992, do not reflect the deduction
of 12b-1 fees because the 12b-1 Plan was implemented on January 1, 1993. The
total returns and average annual total returns of Class A shares quoted from
time to time for periods through April 10, 1991, do not reflect the increased
management fee approved by shareholders on April 10, 1991. The total returns and
average annual returns of the Class A and Class D shares quoted from time to
time for periods through December 31, 1995, do not reflect the increased
management fee approved by shareholders on December 12, 1995, and effective on
January 1, 1996. These fees, if reflected, would reduce the performance quoted.


From time to time, reference may be made in advertising or promotional material
to performance information, including mutual fund rankings, prepared by Lipper
Analytical Services, Inc., an independent reporting service which monitors the
performance of mutual funds. In calculating the total return of the Fund's Class
A, Class B, Class C and Class D shares, the Lipper analysis assumes investment
of all dividends and distributions paid but does not take into account
applicable sales charges. The Fund may also refer in advertisements in other
promotional material to articles, comments, listings and columns in the
financial press pertaining to the Fund's performance. Examples of such financial
and other press publications include BARRON'S, BUSINESS WEEK, CDA/WIESENBERGER

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

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 re-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.

                    Powers of Attorney. (Incorporated by reference to
                    Registrant's Post-Effective Amendment No.74 filed on April
                    29, 1997.)

Item 24.  Persons Controlled by or Under Common Control with Registrant.
          Seligman Data Corp. ("SDC"), a New York corporation, is owned by the
          Registrant and certain associated investment companies. The
          Registrant's investment in SDC is recorded at a cost of $3,553.

Item 25.  Indemnification. Reference is made to the provisions of Articles
          Twelfth and Thirteenth of Registrant's Amended and Restated Articles
          of Incorporation filed as Exhibit 24(b)(1) and Article IV of
          Registrant's Amended and Restated By-laws filed as Exhibit 24(b)(2) to

          Statement.


          Insofar as indemnification for liabilities arising under the

          officers and controlling persons of the Registrant pursuant to the
          foregoing provisions, or otherwise, the Rregistrant 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.

Item 26.  Business and Other Connections of Investment Adviser. J. & W. Seligman
          & Co. Incorporated, a Delaware corporation,), is the Registrant's
          investment manager. Seligman also serves as investment manager to

                                 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
Law and Regulation Department and assume the Code will be interpreted in the
most restrictive manner. Questionable situations should be resolved in favor of
Clients.

<PAGE>


Technical compliance with the Code's procedures will not insulate from scrutiny
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 laws and other applicable laws, such as the prohibition on trading in
securities of an issuer while in possession of material non-public information.

                                 II. Definitions

     (a)  "Accounts" means all Employee Accounts and Employee Related Accounts.

     (b)  "Beneficial Interest" is broadly interpreted. The SEC has said that
          the final determination of Beneficial Interest is a question to be
          determined in the light of the facts of each particular case. The
          terms Employee Account and Employee Related Account, as defined below,
          generally define Beneficial Interest. However, the meaning of
          "Beneficial Interest" may be broader than that described below. If
          there are any questions as to Beneficial Interest, please contact the
          Director of Compliance, General Counsel or Associate General Counsel.

          (i)  "Employee Account" means the following securities Accounts: (i)
               any of your personal account(s); (ii) any joint or
               tenant-in-common account in which you have an interest or are a
               participant; (iii) any account for which you act as trustee,
               executor, or custodian; (iv) any account over which you have
               investment discretion or otherwise can exercise control,
               including the accounts of entities controlled directly or
               indirectly by you; (v) any account in which you have a direct or
               indirect interest through a contract, arrangement or otherwise
               (e.g., economic, voting power, power to buy or sell, or
               otherwise); (vi) any account held by pledges, or for a
               partnership in which you are a member, or by a corporation which
               you should regard as a personal holding company; (vii) any
               account held in the name of another person in which you do not
               have benefits of ownership, but which you can vest or revest
               title in yourself at once or some future time; (viii) any account
               of which you have benefit of ownership; and (ix) accounts
               registered by custodians, brokers, executors or other fiduciaries
               for your benefit.

          (ii) "Employee Related Account" means any Account of (i) your spouse
               and minor children and (ii) any account of relatives or any other
               persons to whose support you materially contribute, directly or
               indirectly.

     (c)  "Disinterested Director" means a director or trustee of a Seligman
          Registered Investment Company who is not an "interested person" of
          such investment company within the meaning of Section 2(a)(19) of the
          Investment Company Act of 1940.

     (d)  "Equivalent Security" includes, among other things, an option to
          purchase or sell a Security or an instrument convertible or
          exchangeable into a Security.

     (e)  "Investment Team" means one or more Investment Teams formed by the
          Manager in various investment disciplines to review and approve
          Securities for purchase and sale by Client Accounts. This includes a
          team's leader, portfolio managers, research analysts, traders and
          their direct supervisors.

     (f)  "Security" includes, among other things, stocks, notes, bonds,
          debentures, and other evidences of indebtedness (including loan
          participation and assignments), limited partnership interests,
          investment contracts, and all derivative instruments (e.g., options
          and warrants).

<PAGE>


     (g)  "Securities Transaction" means a purchase or sale of a Security.

     (h)  "Seligman Registered Investment Company" means an investment company
          registered under the Investment Company Act of 1940 for which Seligman
          serves as investment manager or adviser.

                      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.

<PAGE>


9.   Remedies of the Code

     Upon discovering a violation of this Code, sanctions may be imposed against
     the person concerned as may be deemed appropriate, including, among other
     things, a letter of censure, fines, suspension or termination of personal
     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
     violates the Code must be disgorged to a charitable organization, which you

  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.
