The Fund
 
Investment Objective/Principal Strategies
 
 
The Fund's objectives are to preserve capital and to maximize liquidity and
current income.
 
The Fund uses the following principal strategies to seek its objectives:
 
The Fund invests in US-denominated high-quality money market instruments. Such
instruments include obligations of the US Treasury, its agencies or
instrumentalities, obligations of domestic and foreign banks (such as
certificates of deposit and fixed time deposits), commercial paper and short-
term corporate debt securities, and repurchase agreements with respect to these
types of instruments.
 
The Fund will invest only in US dollar-denominated securities having a
remaining maturity of 13 months (397) days or less and will maintain a US
dollar-weighted average portfolio maturity of 90 days or less.
 
In seeking to maintain a constant net asset value of $1.00, the Fund will limit
its investments to securities that, in accordance with guidelines approved by
the Fund's Board of Directors, present minimal credit risk. Accordingly, the
Fund will only purchase US Government securities, or securities rated in one of
the two highest rating categories assigned to short-term debt securities by at
least two nationally recognized statistical rating organizations (such as
Moody's Investors Service, Inc. (Moody's) or Standard and Poor's Rating Service
(S&P)), or if not so rated, determined to be of comparable quality.
 
Determination of quality is made at the time of investment, and is made in
accordance with procedures approved by the Fund's Board of Directors. If the
quality of investment later declines, the Fund may, in certain limited
circumstances, continue to hold the investment.
 
Presently, the Fund only invests in either US Government securities or
securities that are rated in the top category by Moody's and S&P. However, the
Fund is permitted to invest up to 5% of its assets in securities rated in the
second rating category by two nationally recognized statistical rating
organizations, provided that not more than the greater of 1% of its total
assets or $1,000,000 are invested in any one security.
 
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 are a fundamental policy and may be changed only with the
approval of shareholders. As with any mutual fund, the Fund may not achieve its
investment objectives.
 
                                       1
<PAGE>
 
Principal Risks
 
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. Although the Fund seeks to preserve the value of your investment at
$1.00 per share, it is possible to lose money by investing in the Fund.
 
Yield and total return of the Fund will fluctuate with fluctuations in the
yields of the securities held by the Fund. In periods of declining interest
rates, the yields of the securities held by the Fund will tend to be somewhat
higher than prevailing market rates, and in periods of rising interest rates,
the yields of securities held by the Fund will tend to be lower than market
rates. Additionally, when interest rates are falling, the inflow of new money
to the Fund from the continuous sale of its shares will likely be invested in
securities producing lower yields than the balance of the Fund's assets,
thereby reducing the current yield of the Fund. In periods of rising interest
rates, the opposite may be true.
 
Repurchase agreements in which the Fund invests could involve certain risks in
the event of the default by the seller, including possible delays and expenses
in liquidating the securities underlying the agreement, decline in the value of
the underlying securities and loss of interest.
 
Investments in foreign banks and foreign branches of US banks involve certain
risks not generally associated with investments in US banks. While US banks are
required to maintain certain reserves and are subject to other regulations,
these requirements and regulations may not apply to foreign banks or foreign
branches of US banks. Investments in foreign banks or foreign branches may also
be subject to other risks, including political or economic developments, the
seizure or nationalization of foreign deposits and the establishments of
exchange controls or other restrictions.

Past Performance
 
The Fund offers three Classes of shares. The information in the bar chart
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.
 
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 less. The bar chart assumes that all dividends and capital gain
distributions were reinvested.

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

Management
 
The Fund's Board of Directors provides broad supervision over the affairs of
the Fund.
 
The Fund's manager is J. & W. Seligman & Co. Incorporated (Seligman), 100 Park
Avenue, New York, New York 10017. Seligman manages the investment of the Fund's
assets, including making purchases and sales of portfolio securities consistent
with the Fund's investment objective and strategies, and administers the Fund's
business and other affairs.
 
Established in 1864, Seligman currently serves as manager to 18 US registered
investment companies, which offer more than 50 investment portfolios with
approximately $XX.X billion in assets as of March 31, 1999. Seligman also
provides investment management or advice to institutional or other accounts
having an aggregate value at March 31, 1999, of approximately $XX.X billion.
 
The Fund pays Seligman a fee for its management services. The fee rate equals a
percentage of the daily net assets of the Fund. The rate is calculated on a
sliding scale of 0.45% to 0.375% based on the average daily net assets of all
U.S. registered investment companies managed by Seligman. The fee paid by the
Fund to Seligman for the year ended December 31, 1998, was equal to an annual
rate of .40% of the Fund's average daily net assets.

Year 2000
 
As the millennium approaches, mutual funds, financial and business
organizations, and individuals could be adversely affected if their computer
systems do not properly process and calculate date-related information and data
on and after January 1, 2000. Like other mutual funds, the Fund relies upon
service providers and their computer systems for its day-to-day operations.
Many of the Fund's service providers in turn depend upon computer systems of
their vendors. Seligman and SDC have established a year 2000 project team. The
team's purpose is to assess the state of readiness of Seligman and SDC and the
Fund's other service providers and vendors. The team is comprised of several
information technology and business professionals as well as outside
consultants. The Project Manager of the team reports directly to the
Administrative Committee of Seligman. The Project Manager and other members of
the team also report to the Board of Directors of the Fund and its Audit
Committee.
 
The team has identified the service providers and vendors who furnish critical
services or software systems to the Fund, including securities firms that
execute portfolio transactions for the Fund and firms responsible for
shareholder account recordkeeping. The team is working with these critical
service providers and vendors to evaluate the impact year 2000 issues may have
on their ability to provide uninterrupted services to the Fund. The team will
assess the feasibility of their year 2000 plans. The team has made progress on
its year 2000 contingency plans - recovery efforts the team will employ in the
event that year 2000 issues adversely affect the Fund. The team anticipates
finalizing these plans in the near future.
 
The Fund anticipates the team will implement all significant components of the
team's year 2000 plans by mid-1999, including appropriate testing of critical
systems and receipt of satisfactory assurances from critical service providers
and vendors regarding their year 2000 compliance. The Fund believes that the
critical systems on which it relies will function properly on and after the
year 2000, but this is not guaranteed. If these systems do not function
properly, or the Fund's critical service providers are not successful in
implementing their year 2000 plans, the Fund's operations may be adversely
affected, including pricing, securities trading and settlement, and the
provision of shareholder services.
 
In addition, the Fund may hold securities of issuers whose underlying business
leaves them susceptible to year 2000 issues. The Fund may also hold securities
issued by governmental or quasi-governmental issuers, which, like other
organizations, are also susceptible to year 2000 concerns. Year 2000 issues may
affect an issuer's operations, creditworthiness, and ability to make timely
payment on any indebtedness and could have an adverse impact on the value of
its securities. If the Fund holds these securities, the Fund's performance
could be negatively affected. Seligman seeks to identify an issuer's state of
year 2000 readiness as part of the research it employs. However, the perception
of an issuer's year 2000 preparedness is only one of the many factors
considered in determining whether to buy, sell, or continue to hold a security.
Information provided by issuers concerning their state of readiness may or may
not be accurate or readily available. Further, the Fund may be adversely
affected if the exchanges, markets, depositories, clearing agencies, or
government or third parties responsible for infrastructure needs do not address
their year 2000 issues in a satisfactory manner.
 
SDC has informed the Fund that it does not expect the cost of its services to
increase materially as a result of the modifications to its computer systems
necessary to prepare for the year 2000. The Fund will not pay to remediate the
systems of Seligman or bear directly the costs to remediate the systems of any
other service providers or vendors, other than SDC.

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 is
subject to different ongoing 12b-1 fees. You may only purchase Class B or
Class D shares of the Fund by exchanging shares of the same class of another
Seligman mutual fund or through you broker or financial advisor to facilitate
periodic investments in Class B or Class D shares of other Seligman mutual
funds.
 
When deciding which Class of shares to purchase, you should consider, among
other things:
  . If you would like to participate in a periodic investment program.
  . How long you plan to remain invested in the Fund, or another Seligman
    mutual fund.
  . Whether you may be eligible for reduced or no sales charges when you sell
    shares of the Fund.
 
Your financial advisor will be able to help you decide which Class of shares
best meets your needs.
 
Class A
  . No initial sales charge on purchases. (If you exchange Class A shares of
    the Fund for Class A shares of another Seligman mutual fund, you will be
    subject to an initial sales charge at the time of the exchange.)
 
  . Annual 12b-1 fee (for shareholder services) of up to 0.25%. This fee is
    currently not being charged through April 30, 2000.
 
  . A CDSC of 1% will be imposed on redemptions of Class A shares that were
    acquired by exchange from Class A Shares of another Seligman mutual fund
    purchased within the past 18 months.
 
Class B
  .No initial sales charge on purchases.
  . A declining CDSC on shares sold within 6 years of purchase (or, in the
    case of Class B shares acquired upon exchange, within six years of the
    original Class B shares purchased).

Class D
  . No initial sales charge on purchases.
  . A 1% CDSC on shares sold within one year of purchase (or in the case of
    Class D Shares acquired upon exchange, within one year of the original
    Class D Shares purchased).
  . Annual 12b-1 fee (for distribution and shareholder services) of 1.00%.
  . No automatic conversion to Class A shares, so you will be subject to
    higher ongoing 12b-1 fees indefinitely.
  . No CDSC on redemptions of shares purchased with reinvested dividends or
    capital gain distributions.
 
Because 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, 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 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. 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.

                       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.

The Fund's shares are sold through authorized broker/dealers or financial

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 Fund purchase, and any subsequent
transactions in your account. You will also be sent at least annually, a
statement detailing all your transactions in the Fund and all other Seligman
funds you own. Duplicate account statements will be sent to you free of charge
for the current year and most recent prior year. Copies of year-end statements
for prior years are available for a fee of $10 per year, per account, with a
maximum charge of $150 per account. Send your request and a check for the fee
to SDC.
 
   If you want to be able to buy, sell, or exchange shares by telephone,
    you should complete an application when you open your account. This
   will prevent you from having to complete a supplemental election form
          which may require a signature guarantee at a later date.

How to Buy Additional Shares
 
After you have made your initial investment, there are many options available
to make additional purchases of Fund shares. Shares may be purchased through
your authorized financial advisor, or you may send a check directly to SDC.
Please provide either an investment slip or a note that provides your name(s),
Fund name, and account number. Your investment will be made in the Class you
already own. Send investment checks to:
      Seligman Data Corp.
      P.O. Box 9766
      Providence, RI 02940-5051
 
Your check must be in US dollars and be drawn on a US bank. You may not use
third party or credit card convenience checks for investment.
 
You may also use the following account services to make additional investments:
 
Invest-A-Check(R). You may buy Fund shares electronically from a savings or
checking account of an Automated Clearing House (ACH) member bank. If your bank
is not a member of ACH, the Fund will debit your checking account by
preauthorized checks. You may buy Fund shares at regular monthly intervals in
fixed amounts of $100 or more, or regular quarterly intervals in fixed amounts
of $250 or more. If you use Invest-A-Check(R), you must continue to make
automatic investments until the Fund's minimum initial investment of $1,000 is
met or your account may be closed.
 
Automatic Dollar-Cost-Averaging. If you have at least $5,000 in the Fund, you
may exchange uncertificated shares of the 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, you may pay an initial sales charge to
buy Fund shares, depending on whether the exchanged Class A Shares were owned
as a result of an exchange of shares from another Seligman mutual fund on which
an initial sales charge was paid, in which event you may not pay an initial
sales charges or the initial charge may be reduced.
 
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 MatrixSM. (Requires an initial total investment of
$10,000.) This is a needs-based investment process, designed to help you and
your financial advisor plan to seek your long-term financial goals. It
considers your financial needs, and helps frame a personalized asset allocation
strategy around the cost of your future commitments and the time you have to
meet them. Contact your financial advisor for more information.
 
Seligman Harvester. If you are a retiree or nearing retirement, this program is
designed to help you establish an investment strategy that seeks to meet your
needs throughout your retirement. The strategy is customized to your personal
financial situation by allocating your assets to seek to address your income
requirements, prioritizing your expenses, and establishing a prudent withdrawal
schedule. Contact your financial advisor for more information.

How to Exchange Shares Between 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. An initial sales
charge will be imposed when you exchange Class A shares of the Fund for Class A
shares of another Seligman mutual fund. You may be entitled to a reduced sales
charge on such exchange in certain circumstances. Contact your financial
advisor for more information.
 
Only your dividend 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), which you should read and understand before
investing.

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 always send a written request to sell Fund shares. It may take longer
to get your money if you send your request by mail.
 
You will need to guarantee your signature(s) if the proceeds are:
      (1) $50,000 or more;
      (2) to be paid to someone other than all account owners, or
      (3) mailed to other than your address of record.
 
 
   Signature Guarantee:
   Protects you and the 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.
 
You may need to provide additional documents to sell Fund shares if you are:
 .a corporation;
 .an executor or administrator;
 .a trustee or custodian; or
 .in a retirement plan.
If your Fund shares are represented by certificates, you will need to surrender
the certificates to SDC before you sell your shares.
 
Contact your financial advisor or SDC's Shareholder Services Department for
information on selling your shares under any of the above circumstances.
 
You may also use the following account services to sell Fund shares:
 
Systematic Withdrawal Plan. If you have at least $5,000 in the Fund, you may
withdraw (sell) a fixed 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 initially bought $1,000,000 or more of class
A shares of another Seligman mutual fund without an initial sales charge and
exchanged into class A shares of the Fund your withdrawals may be subject to a
1% CDSC if they occur within 18 months of the original purchase. If you own
Class B or Class D shares and reinvest your dividend distributions, you may
withdraw 12% or 10%, respectively, of the value of your Fund account (at the
time of election) annually without a CDSC.
 
Check Redemption Service. The Check Redemption Service allows a shareholder to
request SDC to provide redemption checks to be drawn on the shareholder's
account in amounts of $500 or more. The shareholder may elect to use this
service on the Account Application or by later written request to SDC Shares
for which certificates have been issued will not be available for redemption
under this service. Contact your financial advisor for more information.

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.

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 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.

all or a part of the proceeds to buy shares of another Seligman mutual fund

exchange of shares from another Seligman mutual fund on which an initial sales
charge was paid you will be eligible to use part or all of the proceeds to buy
shares of another Seligman mutual fund without paying an initial sales charge.
You should consult your tax advisor concerning possible tax consequences of
exercising this privilege.

                         your financial advisor may call SDC. Your request must
                         be received by SDC before the record date to be

                         Dividend distributions are reinvested to buy

                         NAV of the ex-dividend date.
 
                         Dividends on Class B and Class D shares will be lower
                         than the dividends on Class A shares as a result of
                         their higher 12b-1 fees.
 
Taxes
 
The tax treatment of dividend 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.
 
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 on July 12,
1976.


              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 will invest only in US dollar-denominated securities having a remaining
maturity  of 13 months  (397 days) or less and will  maintain a  dollar-weighted
average  portfolio  maturity  of 90  days or  less.  The  Fund  will  limit  its
investments to those securities  that, in accordance with guidelines  adopted by
the Board of Directors, present minimal credit risks. Accordingly, the Fund will
not purchase any security (other than a U.S. Government  security) unless (i) it
is rated in one of the two highest rating categories assigned to short-term debt
securities   by  at  least  two   nationally   recognized   statistical   rating
organizations ("NRSRO's) such as Moody's Investors Service, Inc. ("Moody's") and
Standard  &  Poor's  Rating  Service  ("S&P"),  or (ii) if not so  rated,  it is
determined to be of comparable quality. Determinations of the comparable quality
will be made in accordance with procedures  established by the Directors.  These
standards must be satisfied at the time an investment is made. If the quality of
the investment  later  declines,  the Fund may continue to hold the  investment,
subject in certain  circumstances  to a finding by the Board of  Directors  that
disposing of the investment would not be in the Fund's best interest.

Presently,  the  Fund  only  invests  in  either  US  Government  securities  or
securities that are rated in the top category by Moody's and S&P.  However,  the
Fund is  permitted to invest up to 5% of its assets in  securities  rated in the
second highest rating  category by two NRSRO's,  provided that not more than the
greater of 1% of its total  assets or  $1,000,000  are  invested in any one such
security. A description of the debt securities ratings appears in Appendix "A".

Commercial Paper and Short-Term  Corporate Debt Securities.  The Fund may invest
in commercial paper and short-term  corporate debt securities.  Commercial paper
includes  short-term  unsecured  promissory  notes with maturities not exceeding
nine months issued in bearer form by bank holding  companies,  corporations  and
finance companies to finance short-term credit needs.  Corporate debt securities
include bonds and notes issued by  corporations  to finance  longer-term  credit
needs.  Investments in commercial paper issued by bank holding companies will be
limited at the time of investment  to the 100 largest US bank holding  companies
in terms of assets.

Money  Market  Instruments.  The  Fund  invests  in  high-quality  money  market
instruments  having  a  remaining  maturity  of 13  months  (397  days) or less,
including the following:

US Government,  Agency and  Instrumentality  Obligations.  These  securities are
issued  or  guaranteed  as to  principal  and  interest  by  the  United  States
government or by agencies or instrumentalities  thereof and include a variety of
obligations,  which differ in their  interest  rates,  maturities,  and dates of
issue.  Some of these  obligations  are issued  directly  by the  United  States
Treasury such as U.S. Treasury bills, notes, and bonds; others are guaranteed by
the  U.S.   Treasury,   such  as  securities   issued  by  the  Small   Business
Administration,   the  General   Services   Administration,   and  Farmers  Home
Administration;  others are  supported by the right of the issuer to borrow from
the Treasury, such as securities issued by Federal Home Loan Banks; while others
are supported only by the credit of the agency or instrumentality and not by the
Treasury,   such  as  securities   issued  by  the  Federal  National   Mortgage
Association. There can be


                                       2
<PAGE>

no assurance that the U.S.  Government will provide financial support to such an
agency or instrumentality if it is not obligated to do so by law.

Bank  Obligations.  These  instruments  include  obligations  of domestic  banks
(including  foreign branches) and foreign banks with maturities not exceeding 13
months (397 days)  including  negotiable  certificates  of deposit,  bank notes,
bankers' acceptances,  fixed time deposits and commercial paper.  Investments in
such 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.

Negotiable  certificates  of  deposit  are  certificates  issued  against  funds
deposited  in a bank.  They are for a definite  period of time,  earn a specific
rate of return, and are negotiable.  Bankers'  acceptances are short-term credit
instruments primarily used to finance the import, export, transfer or storage of
goods.  They are  termed  "accepted"  when a bank  guarantees  their  payment at
maturity.  Fixed time deposits represent funds deposited in a bank. They are for
a definite  period of time earn a specific  rate of return.  Fixed time deposits
are made in foreign branches of domestic banks and in foreign banks.  Fixed time
deposits,  unlike  negotiable  certificates of deposit,  generally do not have a
market and may be subject to penalties for early withdrawal of funds.

Investments in foreign banks and foreign branches of United States banks involve
certain risks not generally associated with investments in domestic banks. While
domestic  banks are  required to maintain  certain  reserves  and are subject to
other  regulations,  such  requirements and regulations may not apply to foreign
branches. Investments in foreign banks and branches may also be subject to other
risks,  including  future  political and economic  developments,  the seizure or
nationalization  of foreign deposits and the  establishment of exchange controls
or other restrictions.

Repurchase Agreements. The Fund may enter into repurchase agreements under which
it  acquires a money  market  instrument,  qualified  for  purchase by the Fund,
subject to resale at an agreed upon price and date.  Such resale price  reflects
an agreed upon interest rate  effective for the period of time the instrument is
held by the  Fund  and is  unrelated  to the  interest  rate on the  instrument.
Repurchase  agreements usually are for short periods,  such as one week or less,
but may be for  longer  periods.  Although  the Fund may enter  into  repurchase
agreements with respect to any money market instruments  qualified for purchase,
such agreements generally involve US Government  securities.  The Fund may enter
into repurchase agreements with broker/dealers and commercial banks.  Repurchase
agreements  could  involve  certain  risks in the event of  bankruptcy  or other
default by the seller, including possible delays and expenses in liquidating the
securities  underlying  the  agreement,  decline  in  value  of  the  underlying
securities and loss of interest.

The Fund will not invest more than 10% of its assets in repurchase agreements of
more than one week's  duration and in fixed time deposits,  other than overnight
deposits, subject to withdrawal penalties.

Lending of  Portfolio  Securities.  The Fund may lend  portfolio  securities  to
brokers,  dealers and financial  institutions  provided that cash, or equivalent
collateral,  equal to at least 100% of the market value of the securities loaned
is maintained by the borrower with the Fund. During the time such securities are
on loan, the borrower will pay the Fund any income accruing thereon and the Fund
may invest the cash  collateral  and earn  additional  income or may  receive an
agreed upon fee from the borrower who has delivered equivalent collateral. Loans
are subject to termination  at the option of the Fund or the borrower.  The Fund
may pay reasonable  administrative  and custodial fees in connection with a loan
and  may  pay a  negotiated  portion  of the  interest  earned  on the  cash  or
equivalent  collateral to the borrower or placing broker. The Fund will not lend
more than 25% of the  value of its total  assets,  and it is not  intended  that
payments  received on account of interest paid on securities  loaned will exceed
10% of the  annual  gross  income  of  the  Fund  without  offset  for  realized
short-term  capital  losses,  if any.  The Fund  has not  loaned  any  portfolio
securities to date.

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:

     purposes in an amount not to exceed 5% of the value of the total  assets of
     the Fund;

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

- -    Mortgage or pledge any of its assets, except to the extent, up to a maximum
     of 5% of its total  assets,  necessary  to secure  borrowings  permitted by
     paragraph 1;

     of issuers in any one  industry,  provided that the Fund reserves the right

     Government  or its agencies or  instrumentalities  or banks or bank holding
     companies;

- -    Invest more than 5% of its gross assets (taken at market) in the securities
     of any one  issuer,  other  than  the  U.S.  Government,  its  agencies  or
     instrumentalities, or buy more than 10% of the voting securities of any one
     issuer, other than U.S. Government agencies or instrumentalities;

- -    Buy or hold any real estate or securities of  corporations  or trusts whose

     oil or gas interests, or buy or hold any commodity or commodity contracts;

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.  The  amendments  to the  Management  Agreement,  to
increase the fee rate payable to the Manager by the Fund,  were  approved by the
Board of  Directors on January 17, 1991,  and by the  shareholders  at a special
meeting on April 10, 1991.  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
or by Seligman, 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.

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

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

Officers,  directors,  and  employees  are  required,  except under very limited
circumstances,  to engage in personal securities transactions through Seligman's

employees are also  required to disclose all  securities  beneficially  owned by
them on December 31 of each year.

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, 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 will be  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 over the prior  quarter,  in
accordance with a methodology approved by the Board.

Class A 

Under the  12b-1  Plan,  the  Fund,  with  respect  to Class A  shares,  may pay
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.  Such payments are not
currently being made but may commence after April 30, 2000.  These fees would be
used by Seligman Advisors exclusively to make payments to Service  Organizations
which  have  entered  into  agreements  with  Seligman  Advisors.  Such  Service
Organizations will 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 Fund did not make
payments  under the 12b-1 Plan with  respect  to Class A shares  during the year
ended December 31, 1998.

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. The fee is comprised of (1) a distribution fee equal to .75%
per annum,  which is paid  directly to a third  party,  FEP  Capital,  L.P.,  to
compensate  it for having  funded,  at the time of sale of 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 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, 1998 was $___, equivalent to __% per annum of the average daily net
assets of Class B 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.  The Fee is used by Seligman  Advisors as
follows: During the first year following the sale of Class D shares,


                                       13
<PAGE>


a distribution fee of .75% of the average daily net assets attributable to 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 up to .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 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 assets  invested in the Fund.  The total
amount paid by the Fund in respect of Class D shares for the year ended December
31, 1998 was $___,  equivalent  to __% per annum of the average daily net assets
of Class D shares.

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, 1998  Seligman  Advisors has  incurred  $___ of  unreimbursed
expenses in respect of the Fund's Class D shares. This amount is equal to __% of
the net assets of Class D shares at December 31, 1998.

If the 12b-1 Plan is  terminated  in  respect of Class D shares of the Fund,  no
amounts  (other than amounts  accrued by 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  fiscal  year  ended
December 31,  1998,  were spent on the  following  activities  in the  following
amounts:


                                      Class A(1)      Class B       Class D
                                      ----------      -------       -------

Compensation to underwriters                           $             $

Compensation to broker/dealers          $              $             $

Other*                                                 $

(1)  The Fund did not make payments under the Plan for fiscal year ended 1998.

*    Payment is made to FEP Capital, L. P. to compensate it for having funded at
     the time of sale, payments to broker/dealers and underwriters.

The 12b-1 Plan was  approved  on July 16,  1992 by the  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 Plan or in any  agreement  related to the 12b-1 Plan (the
"Qualified Directors") and was approved by shareholders of the Fund at a Special
Meeting of the Shareholders  held on November 23, 1992.  Although the 12b-1 Plan
became  effective  in respect  of the Class A shares on  January  1,  1993,  the
manager  elected to waive the fee  through  April 30,  1999.  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 D shares on March 18,


                                       14
<PAGE>


1993 by the  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 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.

Seligman  Services acts as a broker/dealer  of record for  shareholder  accounts
that do not have a designated  financial advisor and receives  compensation from
the Fund pursuant to the 12b-1 Plan for providing  personal services and account
maintenance  to such  accounts and other  distribution  services.  For the years
ended December 31, 1998, 1997, and 1996, Seligman Services received distribution
and service fees from the Fund  pursuant to its 12b-1 Plan of $___,  $22,937 and
$10,159, respectively.

                   Portfolio Transactions and Other Practices

Portfolio 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.

Corporate bonds and other  fixed-income  securities are generally  traded on the
over-the-counter  market on a "net" basis without a stated  commission,  through
dealers acting for their own account and not as brokers. The Fund will engage in
transactions with these dealers or deal directly with the issuer. Prices paid to
dealers will generally  include a "spread,"  i.e.,  the  difference  between the
prices at which a dealer is willing to purchase or to sell the  security at that
time.  The  Management  Agreement  recognizes  that in the  purchase and sale of
portfolio securities,  Seligman will seek the most favorable price and execution
and,  consistent  with that  policy,  may give  consideration  to the  research,
statistical  and other services  furnished by dealers to Seligman for its use in
connection with its services to the Fund as well as to other clients.

Commissions

For the fiscal  years ended  December  31, 1998,  1997,  and 1996,  no brokerage
commissions were paid by the Fund.

Dealer 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 dealers to Seligman for its use, as
well as the general attitude toward and support of investment


                                       15
<PAGE>


companies  demonstrated  by such  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  dealers who provide  supplemental
investment and market research and security and economic  analysis  although the
use of such dealers may result in the Fund paying a higher spread,  than the use
of dealers  selected solely on the basis of seeking the most favorable price and
execution  and although  such research and analysis may be useful to Seligman in
connection with its services to clients other than the Fund.

Directed Brokerage

During the year ended  December 31, 1998 neither the Fund nor Seligman  directed
any of the  Fund's  portfolio  transactions  to a  dealer  because  of  research
services provided.

Regular Broker-Dealers

During the year ended December 31, 1998, 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 1,400,000,000  shares of common stock, each with
a par value of $0.01 per share, divided into three classes,  designated Class A,
Class B, and Class D shares. Each share of the Fund's Class A, Class B 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.

The Board of Directors is  authorized  to classify or  reclassify  and issue and
issue any  unissued  common  stock of the Fund into any number of other  classes
without further action by shareholders.

It is the intention of the Fund not to hold Annual Meetings of Shareholders. The
Directors may call Special  Meetings of  Shareholders  for action by shareholder
vote as may be required by the 1940 Act or the Fund's Articles of Incorporation.

Rule 18f-2 under the 1940 Act provides that any matter  required to be submitted
by the provisions of the 1940 Act or applicable state law, or otherwise,  to the
holders of the outstanding  voting  securities of an investment  company such as
the Fund shall not be deemed to have been effectively acted upon unless approved
by the holders of a majority of the outstanding shares of each class affected by
such  matter.  Rule 18f-2  further  provides  that a class shall be deemed to be
affected by a matter  unless it is clear that the interests of each class in the
matter are  substantially  identical  or that the matter does not  significantly
affect any interest of such class.  However,  the Rule exempts the  selection of
independent auditors,  the approval of principal  distributing contracts and the
election of directors from the separate voting requirements of the Rule.

Other Securities

The Fund has no authorized securities other than common stock.

                   Purchase, Redemption, and Pricing of Shares

Purchase of Shares

The Fund issues  three  classes of shares:  Class A shares may be purchased at a
price equal to the next determined net asset value per share. Class B shares and
Class D shares,  which are  available  only  through  an  exchange  of shares of
another  Seligman  Mutual  Fund  offering  Class B  shares  or  Class D  shares,
respectively,  at net  asset  value,  or  through  securities  dealers  or other
financial  intermediaries,  to facilitate periodic investments in Class B shares
or Class D shares, respectively, of other mutual funds in the Seligman Group.

Class A

Since Class A shares of the Fund are offered to  investors  at net asset  value,
only those  shares of the Fund owned as a result of an  exchange  of shares from
another  Seligman  Mutual Fund on which an initial sales charge was paid will be
included for purposes of determining a  shareholder's  eligibility for a reduced
sales charge on additional  investments in Class A shares of the Seligman Mutual
Funds sold with an  initial  sales  charge,  as  described  in each of the other
Seligman  Mutual Funds'  prospectuses  and SAIs. To receive the reduced  initial
sales charge on such additional investments, the shareholder or dealer will have
to notify  Seligman  Advisors at the time of such  additional  investment of the
value of the shares of the Fund  acquired  through an exchange  and the value of
the  additional  investment  to be  included in the  calculation  of the reduced
initial sales charge.

A CDSC of 1% will also be imposed on the  redemption of Class A shares  acquired
by exchange which were  originally  purchased at net asset value due to the size
of the purchase,  if such Class A shares are redeemed  within eighteen months of
the original purchase date.

Class A shares  acquired  by  exchange  which were  originally  purchased  by an
"eligible employee benefit plan" may be subject to a CDSC of 1% for terminations
at the plan level only, on redemptions  of shares  originally  purchased  within
eighteen  months prior to plan  termination.  "Eligible  employee  benefit plan"
means any plan or arrangement,  whether or not tax qualified, which provides for
the  purchase  of Fund  shares  and has at least (i)  $500,000  invested  in the
Seligman  Mutual  Funds or (ii) 50 eligible  employees to whom such plan is made
available.

The 1% CDSC  normally  imposed on  redemptions  of certain  Class A shares (i.e.
those acquired by exchange which were originally  purchased during the preceding
eighteen  months at net asset  value  due to the size of the  purchase)  will be
waived on shares that were purchased through Morgan Stanley Dean Witter & Co. by
certain Chilean investors (i.e.  pension plans,  insurance  companies and mutual
funds).  Upon redemption of such shares within an eighteen month period,  Morgan
Stanley  will  reimburse  Seligman  Advisors  a pro rata  portion  of the fee it
received from Seligman Advisors at the time of sale of such shares.

Class B

Class B shares are sold  without an initial  sales  charge but are  subject to a
CDSC if the shares are redeemed within six years of purchase (or, in the case of
Class B shares  acquired upon exchange,  within six years of the purchase of the
original  Class B Shares)  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%

Approximately   eight  years  after  purchase,   Class  B  shares  will  convert
automatically  into Class A shares of the Fund,  which are  subject to an annual
service  fee of .25% but no  distribution  fee.  Shares  purchased  through  the
reinvestment of dividends on Class B shares also will convert  automatically  to
Class A shares  together 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 on to 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  through  use of the  exchange  privilege  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 Fund from  which the
exchange has been made.

Class D

Class D shares may be  purchased  at a price  equal to the next  determined  net
asset value,  without an initial sales  charge.  Class D shares are subject to a
CDSC of 1% imposed on certain  redemptions  within one year of purchase  (or, in
the  case of Class D  shares  acquired  upon  exchange,  within  one year of the
purchase of the original Class D Shares).

Systematic Withdrawals. Class B and Class D shareholders who reinvest both their
dividends and capital gain  distributions to purchase  additional  shares of the
Fund, may use the Fund's  Systematic  Withdrawal  Plan to withdraw up to 12% 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;


                                       18
<PAGE>


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

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

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

If, with respect to a redemption of any Class A, Class B, 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.

Regardless of the method of redemption, a check for the proceeds ordinarily will
be sent within seven calendar days following

Payment in Securities.  Payment may be made in securities, subject to the review
of some state securities  commissions,  or postponed, if the orderly liquidation
of portfolio  securities is prevented by the closing of, or  restricted  trading
on, the New York Stock  Exchange  during  periods of  emergency,  or during such
other periods as ordered by the Securities and Exchange  Commission.  If payment
were to be made in securities,  shareholders  receiving  securities  could incur
certain transaction costs.

Fund Reorganizations

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.

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 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.

Pursuant to Rule 2a-7 under the 1940 Act, the Fund's  portfolio  securities  are
valued by the amortized cost method. This method of valuation involves valuing a
security at its cost at the time of purchase and thereafter  assuming a constant
amortization to maturity of any discount or premium, regardless of the impact of
fluctuating  interest  rates on the  market  value of the  security.  While this
method  provides  certainty in valuation,  it may result in periods during which
value,  as determined  by amortized  cost, is higher or lower than the price the
Fund would receive if it sold the security. During periods of declining interest
rates, the quoted yield on shares of the Fund may tend to be higher than that of
a fund with  identical  investments  which uses a method of  valuation  based on
market prices and  estimates of market prices for all its portfolio  securities.
Thus, if the use of amortized cost resulted in lower  aggregate  portfolio value
on a particular  day, a prospective  investor would be able to obtain a somewhat
higher


                                       19
<PAGE>


yield if he purchased shares on that day than he would be able to receive from a
fund using  solely  market  values and  existing  investors  would  receive less
investment income. The converse is true in a period of rising interest rates.

The order  permitting  the Fund to use the  amortized  cost method of  valuation
requires that, under the direction of the Board of Directors, certain procedures
be adopted to monitor and stabilize the price per share.  Calculations  are made
to compare the value of its  investments  valued at  amortized  cost with market
values.  Market valuations are obtained by using actual  quotations  provided by
market  markers,  values  obtained  from yield data relating to classes of money
market instruments or US Government securities published by reputable sources at
the mean between the bid and asked prices for the instruments. The Fund will not
maintain a dollar-weighted  average portfolio  maturity in excess of 90 days. In
the event that a  deviation  of 1/2 of 1% or more  exists  between the $1.00 per
share net asset value and the net asset value  calculated by reference to market
quotations,  or if there is any other  deviation  which  the Board of  Directors
believes would result in a material dilution to shareholders or purchasers,  the
Board of  Directors  will  promptly  consider  what  action,  if any,  should be
initiated.

Specimen Price Make-Up

Under  the  current  distribution  arrangements  between  the Fund and  Seligman
Advisors,  Class A, Class B and Class D shares  are sold at  NAV(1).  Using each
Class's NAV at December  31,  1998,  the  maximum  offering  price of the Fund's
shares is as follows:

Class A
     Net asset value and offering price per share(1)..................     $1.00

Class B
     Net asset value and offering price per share(1) .................     $1.00

Class D
     Net asset value and offering price per share(1) .................     $1.00

- --------------
(1)  Class A shares acquired by exchange that were  originally  purchased at net
     asset value due to the size of the  purchase  are subject to a 1% CDSC,  if
     such shares are redeemed within 18 months of the original purchase. 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 subject to a CDSC of 1%
     on redemptions within one year of purchase.

Redemption in Kind

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

                              Taxation of the Fund

The Fund intends to continue to qualify as a regulated  investment company under
the Code.  For each year so  qualified,  the Fund will not be subject to federal
income taxes on its net  investment  income  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.  Dividends  from net  investment  income  are taxed at
ordinary  income  rates  to  the  shareholders,  whether  received  in  cash  or
reinvested in additional shares, and are not eligible for the dividends received
deduction for corporations.


                                       20
<PAGE>


The Fund will  generally  be subject to an excise tax of 4% on the amount of any
income  or  capital  gains,  above  certain  permitted  levels,  distributed  to
shareholders  on a basis  such  that  such  income  or gain  is not  taxable  to
shareholders in the calendar year in which it was earned by the Fund.

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.

      $                              $                      $

(1)  Seligman  Advisors  has sold its  rights to  collect  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, 1998 are reflected in the
     table.

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. Seligman Advisors may from time
to time pay a bonus or other  incentive  to  dealers  that  sell  shares  of the
Seligman  mutual  funds.  Such  bonus  or other  incentive  may take the form of
payment for travel  expenses,  including  lodging,  incurred in connection  with
trips  taken by  qualifying  registered  representatives  and  members  of their
families  to places  within or outside the United  States.  The cost to Seligman
Advisors of such  promotional  activities and payments shall be consistent  with
the rules of the National  Association of Securities  Dealers,  Inc., as then in
effect.

                              Calculation of Yield

The current and  effective  yields of the Class A, Class B and Class D shares of
the  Fund  may be  quoted  in  reports,  sales  literature,  and  advertisements
published by the Fund. The current yield of Class A shares


                                       21
<PAGE>


is computed by determining  the net change  exclusive of capital  changes in the
value of a hypothetical  pre-existing account having a balance of 1 share at the
beginning  of a seven-day  calendar  period,  dividing the net change in account
value  by the  value  of  the  account  at the  beginning  of  the  period,  and
multiplying the return over the seven-day  period by 365/7.  For purposes of the
calculation, net change in account value reflects the value of additional shares
purchased with dividends from the original share and dividends  declared on both
the original share and any such additional shares, but does not reflect realized
gains or losses or unrealized  appreciation or depreciation.  Effective yield is
computed by annualizing  the seven-day  return with all dividends  reinvested in
additional Fund shares.  The current and effective  yields of the Fund's Class B
shares and Class D shares are  computed in the same  manner.  Class B shares and
Class D shares are  subject to a CDSC if shares are held for less than six years
(for Class B shares) or less than one year (for Class D shares). Because Class B
shares  and  Class D shares  bear a  higher  distribution  fee than the  Class A
shares,  the yield of Class B shares  and Class D shares  will be lower than the
yield of Class A shares.

The  following are examples of the yield  calculations  for Class A, Class B and
Class D shares for the seven-day period ended December 31, 1998.

                                   Appendix A

MOODY'S INVESTORS SERVICE, INC. (MOODY'S)
DEBT SECURITIES

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

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

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

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

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

B: Bonds  which are rated B  generally  lack  characteristics  of 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 RATING SERVICE ("S&P")
DEBT SECURITIES

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

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

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

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

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

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

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

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

COMMERCIAL PAPER

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


                                       25
<PAGE>


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

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

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

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

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

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

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

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

Seligman's  beginnings  date back to 1837, when Joseph  Seligman,  the oldest of
eight brothers,  arrived in the United States from Germany. He earned his living
as a pack  peddler in  Pennsylvania,  and began  sending for his  brothers.  The
Seligmans became successful merchants,  establishing businesses in the South and
East.

Backed by nearly thirty years of business  success - culminating  in the sale of
government securities to help finance the Civil War - Joseph Seligman,  with his
brothers,  established the international  banking and investment firm of J. & W.
Seligman & Co. In the years that followed,  the Seligman  Complex played a major
role in the  geographical  expansion and  industrial  development  of the United
States.

The Seligman Complex:

 ...Prior to 1900

o    Helps finance America's fledgling railroads through underwritings.

o    Is admitted to the New York Stock  Exchange  in 1869.  Seligman  remained a
     member of the NYSE until 1993,  when the  evolution of its business made it
     unnecessary.

o    Becomes a prominent underwriter of corporate securities, including New York
     Mutual Gas Light Company, later part of Consolidated Edison.

o    Provides financial  assistance to Mary Todd Lincoln and urges the Senate to
     award her a pension.

o    Is appointed U.S. Navy fiscal agent by President Grant.

o    Becomes a leader in raising  capital  for  America's  industrial  and urban
     development.

 ...1900-1910

     some  of the  Country's  largest  companies:  Briggs  Manufacturing,  Dodge
     Brothers, General Motors,  Minneapolis-Honeywell Regulatory Company, Maytag
     Company, United Artists Theater Circuit and Victor Talking Machine Company.

o    Forms  Tri-Continental  Corporation  in 1929,  today the nation's  largest,
     diversified  closed-end equity investment company,  with over $2 billion in
     assets, and one of its oldest.

 ...1930s

o    Assumes  management of Broad Street  Investing  Co. Inc.,  its first mutual
     fund, today known as Seligman Common Stock Fund, Inc.

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.  Registrant's
          investment in SDC is recorded at a cost of $3,719.

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
          Registrant's  Post-Effective  Amendment  No.  30 to  the  Registration
          Statement.

          Insofar  as   indemnification   for  liabilities   arising  under  the
          Securities  Act of 1933 may be  permitted to  directors,  officers and
          controlling  persons  of the  registrant  pursuant  to  the  foregoing
          provisions,  or  otherwise,  the  registrant  has been  advised by the
          Securities and Exchange  Commission  such  indemnification  is against
          public   policy   as   expressed   in  the  Act  and  is,   therefore,
          unenforceable.  In the event that a claim for indemnification  against
          such liabilities (other than the payment by the registrant of expenses
          incurred or paid by a director,  officer or controlling  person of the
          registrant  in  the  successful   defense  of  any  action,   suit  or
          proceeding)  is  asserted  by such  director,  officer or  controlling
          person  in  connection  with  the  securities  being  registered,  the
          registrant  will,  unless in the opinion of its counsel the matter has
          been  settled  by  controlling   precedent,   submit  to  a  court  of
          appropriate  jurisdiction the question whether such indemnification by
          it is  against  public  policy  as  expressed  in the Act and  will be
          governed by the final adjudication of such issue.

          &  Co.  Incorporated,  a  Delaware  corporation  ("Manager"),  is  the
          Registrant's investment manager. The Manager also serves as investment
