                   SELIGMAN U.S. GOVERNMENT SECURITIES SERIES
                                   a series of

     Seligman  High Income Fund Series (the "Fund") is a  diversified,  open-end
management  investment  company that offers two  different  series which seek to
earn high  current  income by investing in debt  securities  but have  differing
investment   objectives  and  investment   policies.   Investment  advisory  and
management  services  are  provided  to  the  Fund  by J.  & W.  Seligman  & Co.
Incorporated  (the  "Manager");  the Fund's  distributor  is Seligman  Financial
Services, Inc., an affiliate of the Manager.
     The investment objective of the SELIGMAN U.S. GOVERNMENT  SECURITIES SERIES
(the  "Series") is to produce high current  income.  The Series seeks to achieve
its objective by investing primarily in debt obligations issued or guaranteed by
the United States Government,  its agencies or instrumentalities  and by writing
covered call options against such securities.  In order to reduce risks that may
be associated with changes in interest  rates,  the Series may also purchase put
options on such  securities and may engage in  transactions  involving  interest
rate  futures  contracts  and  options on such  contracts.  While  certain  debt
obligations  in the  Series  are  issued  or  guaranteed  by the  United  States
Government  or  by  United  States  Government-related  instrumentalities,  such
investments  are still subject to the risk of market value  fluctuations.  For a
description of the Series' investment objective and policies, including the risk
factors associated with an investment in the Series, see "Investment  Objective,
Policies  And Risks."  There can be no  assurance  that the  Series'  investment
objective will be achieved.

   
     The Series offers three classes of shares.  Class A shares are sold subject
to an initial  sales  load of up to 4.75% and an annual  service  fee  currently
charged  at a rate of up to .25% of the  average  daily net  asset  value of the
Class A shares.  Class A shares purchased in an amount of $1,000,000 or more are
sold  without an initial  sales load but are  subject to a  contingent  deferred
sales load ("CDSL") of 1% on redemptions  within 18 months of purchase.  Class B
shares  are sold  without an initial  sales load but are  subject to a CDSL,  if
applicable,  of 5% on  redemptions  in the first  year  after  purchase  of such
shares,  declining  to 1% in  the  sixth  year  and  0%  thereafter,  an  annual
distribution  fee of .75% and an annual service fee of up to .25% of the average
daily  net  asset  value of the  Class B  shares.  Class B shares  will  convert
automatically  to Class A shares on the last day of the month that  precedes the
eighth anniversary of their date of purchase. Class D shares are sold without an
initial  sales  load  but  are  subject  to a  CDSL  of 1%  imposed  on  certain
redemptions  within one year of purchase,  an annual  distribution  fee of up to
 .75% and an  annual  service  fee of up to .25% of the  average  daily net asset
value of the Class D shares.  Any CDSL payable upon redemption of shares will be
assessed on the lesser of the current net asset value or the  original  purchase
price of the shares redeemed. No CDSL will be imposed on shares acquired through
the  reinvestment  of  dividends  or  distributions  received  from any class of
shares.  See  "Alternative  Distribution  System."  Shares of the  Series may be
purchased through any authorized investment dealer.

</TABLE>


     The  purpose  of this table is to assist  investors  in  understanding  the
various  costs and expenses  which  shareholders  of the Series bear directly or
indirectly.  The sales load on Class A shares is a one-time  charge  paid at the
time of purchase of shares.  Reductions  in initial sales loads are available in
certain circumstances.  The contingent deferred sales loads on Class B and Class
D shares are one-time  charges paid only if shares are redeemed within six years
or one year of  purchase,  respectively.  Class A shares  are not  subject to an
initial sales load for purchases of $1,000,000 or more; however, such shares are
subject to a  contingent  deferred  sales load, a one-time  charge,  only if the
shares are redeemed  within eighteen  months of purchase.  The "Other  Expenses"
disclosed  for Class A and Class D shares  have been  restated  to  reflect  the
expense  allocation  methodology  currently  being used by the Series.  For more
information  concerning  reductions  in  sales  loads  and  for a more  complete
description  of the  various  costs and  expenses,  see  "Purchase  Of  Shares",
"Redemption  Of  Shares"  and   "Management   Services"   herein.   The  Series'
Administration,  Shareholder Services and Distribution Plan to which the caption
"12b-1 Fees" relates, is discussed under  "Administration,  Shareholder Services
and Distribution  Plan" herein.

EXAMPLE:                              1 YEAR     3 YEARS     5 YEARS    10 YEARS
                                      ------     -------     -------    --------

You would pay the following expenses
on  a  $1,000  investment,  assuming
(1)  5%  annual   return   and   (2)
redemption  at  the   end  of   each
time  period.................Class A    $59        $83        $108        $182
                             Class B+   $70        $91        $125        $207
                             Class D    $30++      $61        $105        $227

The  example  should  not be  considered  a  representation  of past  or  future
expenses.  Actual  expenses  may be greater or less than those  shown and the 5%
annual return used in this example is a hypothetical rate.

 * Expenses  for Class B shares  are  estimated  because no shares of that Class
   were outstanding in the year ended December 31, 1995.

** Includes an annual  distribution  fee of up to .75% and an annual service fee
   of up to  .25%.  Pursuant  to  the  Rules  of  the  National  Association  of
   Securities  Dealers,  Inc.  the  aggregate  deferred  sales  loads and annual
   distribution  fees on Class B and Class D shares of the Series may not exceed
   6.25%  of total  gross  sales,  subject  to  certain  exclusions.  The  6.25%
   limitation is imposed on the Series rather than on a per  shareholder  basis.
   Therefore,  a long-term  Class B or Class D shareholder of the Series may pay
   more in total sales loads  (including  distribution  fees) than the  economic
   equivalent of 6.25% of such shareholder's investment in such shares.
 + Assuming (1) 5% annual return and (2) no redemption at the end of the period,
   the expenses on a $1,000  investment  would be $20 for 1 year, 61 for 3 years
   and $105 for 5 years.
++ Assuming (1) 5% annual  return and (2) no  redemption at the end of one year,
   the expenses on a $1,000 investment would be $20.

                              FINANCIAL HIGHLIGHTS

   
     The financial highlights for the Series' Class A and Class D shares for the
periods presented below have been audited by Deloitte & Touche LLP,  independent
auditors.  This information,  which is derived from the financial and accounting
records  of the  Series  should  be  read  in  conjunction  with  the  financial
statements  and notes  contained  in the Fund's 1995 Annual  Report and June 30,
1996  Mid-Year  Report,  which  are  incorporated  by  reference  in the  Fund's
Statement of  Additional  Information,  copies of which may be obtained  free of
charge from the Fund at the telephone  numbers or address  provided on the cover
page of this Prospectus.  Financial Highlights are not presented for the Class B
shares because no shares of that Class were  outstanding  during the periods set
forth below.

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

ALTERNATIVE DISTRIBUTION SYSTEM

     The Series  offers  three  classes  of  shares.  Class A shares are sold to
investors who have concluded that they would prefer to pay an initial sales load
and have  the  benefit  of lower  continuing  fees.  Class B shares  are sold to
investors choosing to pay no initial sales load, a higher distribution fee and a
CDSL with  respect to  redemptions  within six years of purchase  and who desire
shares to convert  automatically  to Class A shares after eight  years.  Class D
shares are sold to  investors  choosing to pay no initial  sales load,  a higher
distribution fee and, with respect to redemptions within one year of purchase, a
CDSL. The Alternative  Distribution System allows investors to choose the method
of  purchasing  shares  that is most  beneficial  in light of the  amount of the
purchase,  the  length  of time the  shares  are  expected  to be held and other
relevant   circumstances.   Investors  should  determine   whether  under  their
particular  circumstances it is more advantageous to incur an initial sales load
and be subject to lower ongoing fees, as discussed  below, or to have the entire
initial  purchase price  invested in the Series with the  investment  thereafter
being  subject to higher  ongoing  fees and either a CDSL for a six-year  period
with  automatic  conversion  to Class A shares after eight years or a CDSL for a
one-year period with no automatic conversion to Class A shares.

     Investors who expect to maintain their investment for an extended period of
time might choose to purchase Class A shares  because over time the  accumulated
continuing  distribution  fees of Class B and  Class D  shares  may  exceed  the
initial  sales  load  and  lower  distribution  fee  of  Class  A  shares.  This
consideration  must be weighed  against the fact that the amount invested in the
Series will be reduced by the initial  sales load on Class A shares  deducted at
the time of purchase.  Furthermore,  the higher distribution fees on Class B and
Class D shares  will be offset to the  extent  any  return  is  realized  on the
additional  funds initially  invested  therein that would have been equal to the
amount of the initial sales load on Class A shares.

     Investors who qualify for reduced  initial sales loads,  as described under
"Purchase Of Shares" below, might also choose to purchase Class A shares because
the initial sales load deducted at the time of purchase would be less.  However,
investors  should  consider the effect of the 1% CDSL imposed on shares on which
the initial sales load was waived because the amount of Class A shares purchased
reached $1,000,000.  In addition,  Class B shares will be converted into Class A
shares after a period of  approximately  eight years,  and thereafter  investors
will be subject to lower ongoing fees. 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.

     Alternatively,  some  investors  might  choose  to have all of their  funds
invested initially in Class B or Class D shares, although remaining subject to a
higher  continuing  distribution  fee and, for a six-year or one-year  period, a
CDSL as  described  below.  For  example,  an investor  who does not qualify for
reduced  sales  loads would have to hold Class A shares for more than 6.33 years
for the Class B or Class D  distribution  fee to exceed the  initial  sales load
plus the  distribution  fee on Class A shares.  This  example does not take into
account the time value of money, which further reduces the impact of the Class B
and Class D shares' 1% distribution  fee, other expenses  charged to each class,
fluctuations  in net asset  value or the effect of the return on the  investment
over this period of time.

     Investors  should bear in mind that the total  asset  based  sales  charges
(i.e., the higher  continuing  distribution fee plus the CDSL) on Class B shares
that are redeemed  may exceed the total asset based sales  charges that would be
payable  on the same  amount of Class A or Class D shares,  particularly  if the
Class B shares are redeemed shortly after purchase or if the investor  qualifies
for a reduced sales load on the Class A shares.

     Investors  should  understand  that the purpose and function of the initial
sales load (and deferred sales load,  when  applicable)  with respect to Class A
shares is the same as those of the deferred sales loads and higher  distribution
fees with  respect  to Class B and  Class D shares  in that the sales  loads and
distribution  fees  applicable  to each class  provide for the  financing of the
distribution of the shares of the Series.

                                       4
<PAGE>

     Class B and Class D shares  are  subject to the same  ongoing  distribution
fees but Class D shares are subject to a CDSL for a shorter  period of time (one
year as opposed  to six years)  than  Class B shares.  However,  unlike  Class D
shares,  Class B shares  automatically  convert  to Class A  shares,  which  are
subject to lower ongoing distribution fees.

     The three classes of shares  represent  interests in the same  portfolio of
investments,  have the same rights and are  generally  identical in all respects
except that each class bears its separate distribution and, 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 Investment  Company Act
of 1940,  as amended  (the "1940  Act"),  or  Massachusetts  law. The net income
attributable  to each  class and  dividends  payable on the shares of each class
will be reduced by the amount of distribution  and other expenses of each class.
Class B and Class D shares bear higher  distribution  fees, which will cause the
Class B and Class D shares to pay lower  dividends than the Class A shares.  The
three classes also have separate exchange privileges.

     The  Trustees of the Fund  believe  that no conflict of interest  currently
exists  between  the Class A,  Class B and Class D shares of the  Series.  On an
ongoing basis, the Trustees, in the exercise of their fiduciary duties under the
1940 Act and  Massachusetts  law,  will  seek to  ensure  that no such  conflict
arises. For this purpose, the Trustees will monitor the Series for the existence
of any  material  conflict  among the  classes  and will take such  action as is
reasonably necessary to eliminate any such conflicts that may develop.

     DIFFERENCES BETWEEN CLASSES. The primary differences between Class A, Class
B and Class D shares are their sales load structures and ongoing expenses as set
forth below. The primary differences between Class B and Class D shares are that
Class D shares are  subject to a shorter  CDSL  period and a lower CDSL rate but
Class B  shares  automatically  convert  to Class A shares  after  eight  years,
resulting in a reduction  in ongoing  fees.  Investors in Class B shares  should
take into account  whether  they intend to redeem  their shares  within the CDSL
period and, if not,  whether they intend to remain invested until the end of the
conversion  period and thereby take  advantage of the  reduction in ongoing fees
resulting from the conversion to Class A shares.  Other investors,  however, may
elect to purchase Class D shares if they determine  that it is  advantageous  to
have all their assets invested initially and they are uncertain as to the length
of time they intend to hold their assets in the Series or another mutual fund in
the Seligman Group for which the exchange privilege is available. Although Class
D shareholders  are subject to a shorter CDSL period at a lower rate, they forgo
the Class B automatic  conversion  feature,  making their investment  subject to
higher  distribution  fees for an  indefinite  period  of time.  Each  class has
advantages  and  disadvantages  for different  investors,  and investors  should
choose the class that best suits their circumstances and their objectives.

*Conversion occurs at the end of the month which precedes the 8th anniversary of
 the purchase  date.  If Class B shares of the Series 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.

INVESTMENT OBJECTIVE, POLICIES AND RISKS

     The Fund is a diversified open-end management  investment company organized
under the laws of the  Commonwealth of  Massachusetts  by a Declaration of Trust
dated July 27, 1984. The Fund offers one other separate  investment  series: the
Seligman   High-Yield  Bond  Series.  The  High-Yield  Bond  Series'  investment
objective  and  policies  and other  important  information  with respect to its
operations are set forth in a separate Prospectus.

     The objective of the Series is to produce high current  income.  The Series
seeks to achieve its  objective  by  investing  at least 80% of the value of its
total assets in direct obligations of the U.S. Treasury, such as Treasury Bills,
Treasury Notes and Treasury Bonds,  and in debt securities  issued or guaranteed
by the U.S. Government, its agencies or instrumentalities and backed by the full
faith and credit of the U.S.  Government which have maturities  greater than one
year at the date of  purchase  by the  Series,  except for  temporary  defensive
purposes.  This investment policy is a fundamental policy and may not be changed
by the  Trustees  of the Fund  without  the vote of a  majority  of the  Series'
outstanding voting securities (as defined below). There can be no assurance that
the Series' investment objective will be obtained.

     The Series may invest up to 20% of the value of its total  assets in direct
obligations of the U.S.  Treasury and in securities  issued or guaranteed by the
United  States  Government,   its  agencies  or  instrumentalities   which  have
maturities  of less  than  one  year  at the  date of  purchase  by the  Series.
Obligations  issued by U.S.  Government  agencies include  obligations issued by
such entities as Federal Land Banks,  Federal Home Loan Banks and the Government
National  Mortgage  Association   ("GNMA").   "GNMA  Certificates"  or  "GNMAs,"
represent  interests in pools of  residential  mortgages.  The timely payment of
principal  and interest is  guaranteed  by GNMA and backed by the full faith and
credit of the U.S. Government.  GNMAs differ from other forms of debt securities
which  normally  provide for periodic  payment of interest in fixed amounts with
principal payments at maturity or specified call dates. Instead, GNMAs provide a
"pass  through"  of monthly  payments  of  interest  and  principal  made by the
borrowers on their residential mortgage loans, net of certain expenses. A pool's
stated  maturity may be shortened by  prepayments of principal on the underlying
mortgage  obligations.  Factors affecting mortgage  prepayments  include,  among
other  things,  the  level  of  interest  rates,  general  economic  and  social
conditions  and the  location  and age of the  mortgage.  Such  prepayments  may
shorten the effective  maturity of GNMAs.  High interest rate mortgages are more
likely to be prepaid  than lower rate  mortgages;  consequently,  the  effective
maturities  of GNMAs with pass  through  payments of higher rate  mortgages  are
likely to be shorter than those of  obligations  with pass  through  payments of
lower rate mortgages.

     LENDING OF PORTFOLIO  SECURITIES.  The Series may lend portfolio securities
to brokers or dealers,  banks, or other  institutional  borrowers of securities.
The borrower must maintain with the Series cash or equivalent collateral such as
Treasury  Bills,  equal to at least 100% of the market  value of the  securities
loaned.  During the time portfolio securities are on loan, the borrower pays the
Series any income  accruing on the loaned  securities  and the Series may invest
the cash  collateral  and earn  additional  income or may receive an agreed upon
amount of interest income from the borrower. The lending of portfolio securities
may involve  certain  risks such as: 1) an  increase in the market  value of the
borrowed securities without a corresponding  increase in the value of the posted
collateral might result in an imbalance in value between the borrowed securities
and the  collateral;  2) in the event the borrower sought  protection  under the
Federal bankruptcy laws,  repayment of the borrowed securities to the Fund might
be delayed;  and 3) the borrower might refuse to repay the borrowed  securities.
The Series may lend  portfolio  securities  to the extent that the Manager deems
appropriate in seeking to achieve the Series' investment objective and with only
a prudent degree of risk.

     REPURCHASE AGREEMENTS. The Series may enter into repurchase agreements with
commercial banks and with  broker/dealers  to invest cash for the short-term.  A

                                       6
<PAGE>

repurchase  agreement  is an agreement  under which the Series  acquires a money
market instrument, generally a U.S. Government obligation qualified for purchase
by the Series,  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 Series and is unrelated  to the interest  rate on the
instrument.  Repurchase  agreements  could involve certain risks in the event of
bankruptcy  or other  default  by the  seller,  including  possible  delays  and
expenses in  liquidating  the securities  underlying  the agreement,  decline in
value of the underlying  securities and loss of interest.  Repurchase agreements
usually are for short  periods,  such as one week or less, but may be for longer
periods.  Although the Series may enter into repurchase  agreements with respect
to  any  money  market  instruments  qualified  for  purchase,  such  agreements
generally involve U.S.  Government  securities and will only involve  securities
issued or guaranteed by the U.S. Government.  As a matter of fundamental policy,
the Series  will not enter into  repurchase  agreements  of more than one week's
duration  if more  than  10% of its  total  assets  would  be  invested  in such
agreements and in restricted and other illiquid securities.

     WHEN-ISSUED SECURITIES. The Series may purchase securities on a when-issued
basis,  in which case  delivery and payment  normally  take place within 45 days
after the date of the  commitment to purchase.  The payment  obligation  and the
interest rate that will be received on the securities are each fixed at the time
the buyer enters into the  commitment.  Although the Series will only purchase a
security on a  when-issued  basis with the  intention of actually  acquiring the
securities,  the Series may sell these securities before the purchase settlement
date if it is deemed advisable.

     Securities  held by the Series and  securities  purchased on a  when-issued
basis are subject to changes in market value based upon  investors'  perceptions
of the creditworthiness of the issuer and upon changes, real or anticipated,  in
the level of interest rates. If the Series remains  substantially fully invested
at the same time that it has purchased  securities on a when-issued  basis,  the
market value of the Series' assets may fluctuate  more than  otherwise  would be
the case.  Purchasing a security on a when-issued  basis can involve a risk that
the yields  available in the market when the delivery  takes place may be higher
than those obtained on the security so purchased.

     An account  for the Series  consisting  of cash or liquid  high-grade  debt
securities  equal  to  the  amount  of  the  when-issued   commitments  will  be
established  with the  Series'  Custodian,  and  marked  to market  daily,  with
additional cash or liquid high-grade debt securities added when necessary.  When
the time  comes to pay for  when-issued  securities,  the  Series  will meet its
respective obligations from then available cash flow, sale of securities held in
the separate  account,  sale of other  securities  or,  although  they would not
normally expect to do so, from the sale of the when-issued securities themselves
(which may have a value greater or less than the Series'  payment  obligations).
Sale of securities to meet such obligations  carries with it a greater potential
for the realization of capital gain or loss.

     GENERAL.   Except  as  noted  above  or  in  the  Statement  of  Additional
Information,  the  foregoing  investment  policies are not  fundamental  and the
Trustees of the Fund may change such policies  without the vote of a majority of
the  outstanding  voting  securities of the Series.  As a matter of policy,  the
Trustees  will not change the Series'  investment  objective of  producing  high
current income without such a vote.  Under the 1940 Act a "vote of a majority of
the outstanding  voting  securities" of the Series means the affirmative vote of
the lesser of (1) more than 50% of the  outstanding  shares of the Series or (2)
67% or more of the shares of the Series  present at a  shareholders'  meeting if
more than 50% of the  outstanding  shares of the Series are  represented  at the
meeting in person or by proxy.

MANAGEMENT SERVICES

     The Trustees  provide broad  supervision over the affairs of the Series and
the Fund as a whole. Pursuant

                                       7
<PAGE>

to a Management  Agreement  approved by the Trustees and the shareholders of the
Series,  the Manager  manages the  investments of the Series and administers the
business and other affairs of the Series. The address of the Manager is 100 Park
Avenue, New York, NY 10017.

   
     The Manager also serves as manager of sixteen  other  investment  companies
which,  together with the Fund,  comprise the "Seligman  Group." These companies
are: Seligman Capital Fund, Inc.,  Seligman Cash Management Fund, Inc., Seligman
Common Stock Fund, Inc.,  Seligman  Communications  and Information  Fund, Inc.,
Seligman  Frontier Fund, Inc.,  Seligman Growth Fund, Inc.,  Seligman  Henderson
Global Fund  Series,  Inc.,  Seligman  Income  Fund,  Inc.,  Seligman New Jersey
Tax-Exempt Fund, Inc., Seligman  Pennsylvania  Tax-Exempt Fund Series,  Seligman
Portfolios,  Inc.,  Seligman  Quality  Municipal  Fund,  Inc.,  Seligman  Select
Municipal Fund, Inc., Seligman Tax-Exempt Fund Series, Inc., Seligman Tax-Exempt
Series  Trust  and  Tri-Continental  Corporation.  The  aggregate  assets of the
Seligman  Group were  approximately  $14.4  billion at November  30,  1996.  The
Manager also provides investment management or advice to institutional  accounts
having an aggregate value at November 30, 1996 of approximately $4.2 billion.
    

     Mr. William C. Morris is Chairman and President of the Manager and Chairman
of the Board and Chief Executive Officer of the Fund. Mr. Morris owns a majority
of the outstanding voting securities of the Manager.

     The  Manager  provides  senior   management  for  Seligman  Data  Corp.,  a
wholly-owned  subsidiary of certain investment  companies in the Seligman Group,
which  performs,  at  cost,  certain  recordkeeping  functions  for the  Series,
maintains the records of shareholder accounts
and furnishes dividend paying, redemption and related services.

     The Manager is entitled to receive a management fee,  calculated  daily and
payable monthly,  equal to .50% of the daily average net assets of the Series on
an annual basis.  The Fund pays all of its expenses  other than those assumed by
the Manager. The Fund's expenses are allocated among the series of the Fund in a
manner  determined by the Trustees to be fair and  equitable.  Total expenses of
the  Series'  Class A and Class D shares for the year ended  December  31,  1995
amounted to 1.14% and 2.01%,  respectively,  of the average  daily net assets of
each class. No Class B shares of the Series were outstanding during this period.

     PORTFOLIO  MANAGER.  Mr. Leonard J. Lovito,  Vice President of the Manager,
has been Vice President and Portfolio  Manager of the Series since January 1994.
Mr. Lovito also serves as Vice President and Portfolio  Manager of Seligman Cash
Management  Fund, Inc. and Vice President of Seligman  Portfolios,  Inc. ("SPI")
and Portfolio  Manager of SPI's Seligman Cash Management  Portfolio and Seligman
Fixed Income Securities  Port-folio.  Mr. Lovito joined the Manager in 1984 as a
fixed  income  trader  and has more than 11 years of fixed  income  trading  and
portfolio management experience.

     The Manager's discussion of the Series' performance as well as a line graph
illustrating  comparative  performance  information  between  the Series and the
Lehman Brothers  Government/Mortgage  Index, the Lipper General U.S.  Government
Funds  Index and the Lehman  Brothers  Government  Bond Index is included in the
Fund's 1995 Annual Report to Shareholders.  Copies of the 1995 Annual Report may
be obtained,  without  charge,  by calling or writing the Fund at the  telephone
numbers or address listed on the cover page of this Prospectus.

     PORTFOLIO TRANSACTIONS. 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 Series 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,  the  Manager  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 the Manger for
its use in connection with its services to the Fund as well as to other clients.

                                       8
<PAGE>

     Consistent  with  the  Rules  of the  National  Association  of  Securities
Dealers,  Inc.  and subject to seeking the most  favorable  price and  execution
available and such other policies as the Trustees of the Fund may determine, the
Manager  may  consider  sales of shares of the Series and,  if  permitted  under
applicable  laws,  may consider sales of shares of the other mutual funds in the
Seligman  Group as a factor in the  selection  of  brokers or dealers to execute
portfolio transactions for the Series.

     PORTFOLIO  TURNOVER.  A change in securities held by the Series is known as
"portfolio  turnover"  which may  result in the  payment by the Series of dealer
spreads or underwriting  commissions and other transactions costs on the sale of
securities as well as on the  reinvestment of the proceeds in other  securities.
Although  it is the  policy of the  Series to hold  securities  for  investment,
changes  will be made from time to time when the Manager  believes  such changes
will  strengthen the Series'  portfolio.  The portfolio  turnover rate will vary
from year to year as well as within a year and may  exceed  100% and has done so
in prior years.

PURCHASE OF SHARES

     Seligman Financial  Services,  Inc. ("SFSI"),  an affiliate of the Manager,
acts as general  distributor  of the  Series'  shares.  Its  address is 100 Park
Avenue, New York, NY 10017.

     The Fund  issues  three  classes  of  shares:  Class A  shares  are sold to
investors  choosing the initial sales load alternative;  Class B shares are sold
to investors  choosing to pay no initial sales load, a higher  distribution  fee
and a CDSL with  respect to  redemptions  within six years of  purchase  and who
desire shares to convert  automatically to Class A shares after eight years; and
Class D shares are sold to  investors  choosing no initial  sales load, a higher
distribution  fee and a CDSL on  redemptions  within one year of  purchase.  See
"Alternative Distribution System" above.

     Shares of the Series may be  purchased  through any  authorized  investment
dealer.  All  orders  will be  executed  at the net asset  value per share  next
computed  after  receipt  of the  purchase  order  plus,  in the case of Class A
shares, a sales load which, except for shares purchased under one of the reduced
sales  load  plans,  will  vary  with the size of the  purchase  as shown in the
schedule under "Class A Shares -- Initial Sales Load" below.

     THE  MINIMUM  AMOUNT  FOR  INITIAL  INVESTMENT  IN THE  SERIES  IS  $1,000;
SUBSEQUENT  INVESTMENTS  MUST  BE IN THE  MINIMUM  AMOUNT  OF $100  (EXCEPT  FOR
INVESTMENT OF DIVIDENDS AND CAPITAL GAIN  DISTRIBUTIONS).  THE FUND RESERVES THE
RIGHT TO RETURN  INVESTMENTS  WHICH DO NOT MEET THESE  MINIMUMS.  EXCEPTIONS  TO
THESE MINIMUMS ARE AVAILABLE FOR ACCOUNTS BEING  ESTABLISHED  CONCURRENTLY  WITH
THE INVEST-A-CHECK(R) SERVICE OR THE SELIGMAN TIME HORIZON MATRIXSM.

     No  purchase  order  may be  placed  for  Class B shares  for an  amount of
$250,000 or more.

     Orders  received by an  authorized  dealer before the close of the New York
Stock Exchange ("NYSE") (normally,  4:00 p.m. Eastern time) and accepted by SFSI
before the close of business  (5:00 p.m.  Eastern  time) on the same day will be
executed at the Series' net asset value  determined  as of the close of the NYSE
on that day plus,  in the case of Class A shares,  any  applicable  sales  load.
Orders  accepted  by dealers  after the close of the NYSE,  or  received by SFSI
after the close of business,  will be executed at the Series' net asset value as
next determined plus, in the case of Class A shares,  any applicable sales load.
The  authorized   dealer  through  which  a  shareholder   purchases  shares  is
responsible for forwarding the order to SFSI promptly.

     Payment  for  dealer  purchases  may be made by check  or by wire.  To wire
payment,  dealer  orders  must  first be placed  through  SFSI's  order desk and
assigned a purchase  confirmation  number.  Funds in payment of the purchase may
then be wired to Mellon Bank, N.A., ABA #043000261, A/C Seligman U.S. Government
Securities  Series (A, B or D), A/C  #107-1011.  WIRE TRANSFERS MUST INCLUDE THE
PURCHASE CONFIRMATION NUMBER AND CLIENT ACCOUNT REGISTRATION AND ACCOUNT NUMBER.
Persons other than dealers who wish to wire payment should contact Seligman Data
Corp. for specific wire instructions. Although the Fund makes no charge for this
service, the transmitting bank may impose a wire service fee.

                                       9

     Current  shareholders may purchase  additional shares of the Series through
any  authorized  dealer or by sending a check payable to the "Seligman  Group of
Funds" in our  postage-paid  return  envelope or directly to P.O. BOX 3947,  NEW
YORK, NY 10008-3947.  Checks for investment  must be in U.S.  dollars drawn on a
domestic bank.  The check should be accompanied by an investment  slip (provided
on the bottom of shareholder  account  statements or with periodic  reports) and
include the  shareholder's  name,  address,  account number,  name of Series and
class of shares (A, B or D). If a  shareholder  does not  provide  the  required
information,  Seligman  Data Corp.  will seek further  clarification  and may be
forced to return the check to the shareholder.  Orders sent directly to Seligman
Data Corp. will be executed at the Series' net asset value next determined after
the order is accepted plus, in the case of Class A shares,  any applicable sales
load.
    

     Seligman Data Corp. will charge a $10.00 service fee for checks returned to
it as uncollectable. This charge may be deducted from the shareholder's account.
For the protection of the Fund and its shareholders, no redemption proceeds will
be remitted to a shareholder  with respect to shares  purchased by check (unless
certified) until Seligman Data Corp. receives notice that the check has cleared,
which may be up to 15 days from the  credit of the  shares to the  shareholder's
account.

     VALUATION.  The net asset value of the Series'  shares is  determined  each
day,  Monday through  Friday,  as of the close of trading on the NYSE (normally,
4:00  p.m.  Eastern  time) on each day that the NYSE is open for  business.  Net
asset value is calculated  separately  for each class.  Securities are valued at
market  value  or,  in the  absence  thereof,  at fair  value as  determined  in
accordance with procedures approved by the Fund's Trustees.  Short-term holdings
maturing  in 60 days or less are  valued  at  amortized  cost if their  original
maturity was 60 days or less and securities  purchased with maturities in excess
of 60 days  which  currently  have  maturities  of 60 days or less are valued by
amortizing their fair market value on the 61st day prior to maturity.

     Although  the  legal  rights  of Class A,  Class B and  Class D shares  are
substantially  identical, the different expenses borne by each class will result
in different net asset values and dividends.  The net asset value of Class B and
Class D shares  will  generally  be lower  than the net  asset  value of Class A
shares as a result of the higher  distribution fees charged to Class B and Class
D shares.  In addition,  net asset value per share of the three  classes will be
affected to the extent any other expenses differ among classes.

     CLASS A  SHARES--INITIAL  SALES  LOAD.  Class A shares  are  subject  to an
initial  sales load which  varies with the size of the  purchase as shown in the
following schedule, and an annual service fee of up to .25% of the average daily
net asset value of Class A shares. See "Administration, Shareholder Services and
Distribution Plan" below. There is no initial sales load on purchases of Class A
shares of $1,000,000 or more;  however,  such shares are subject to a CDSL of 1%
if redeemed within 18 months of purchase.

     SFSI shall pay  broker/dealers,  from its own resources,  a fee on sales of
$1,000,000  or  more,  calculated  as  follows:  1.00%  of  sales  up to but not
including $2 million;  .80% of sales from $2 million up to but not  including $3
million; .50% of sales from $3 million up to

                                       10
<PAGE>

but not including $5 million;  and .25% of sales from $5 million and above.  The
calculation  of the fee will be based on  assets  held by a "single  person"  as
defined below.

   
     SFSI shall pay broker/dealers, from its own resources, an additional fee on
assets of certain  Class A shares of the Seligman  Mutual  Funds,  including the
Series,  participating in an "eligible  employee benefit plan" (as defined below
under "Special Programs") that are attributable to the particular broker/dealer.
The shares eligible for the fee are those on which an initial sales load was not
paid because  either the  participating  eligible  employee  benefit plan has at
least (i)  $500,000  invested in the  Seligman  Group of Mutual Funds or (ii) 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  during a calendar  year,  or  portion  thereof.  The  payment
schedule,  for each calendar  year, is as follows:  1.00% of sales up to but not
including $2 million;  .80% of sales from $2 million up to but not  including $3
million;  .50% of sales from $3 million up to but not including $5 million;  and
 .25% of sales from $5 million and above.
    

     REDUCED  SALES LOADS.  Reductions in initial sales loads apply to purchases
of Class A shares by a "single  person,"  including an individual,  members of a
family unit comprising husband,  wife, and minor children purchasing  securities
for their own account,  or a trustee or other fiduciary  purchasing for a single
fiduciary  account  or  single  trust.  Purchases  made by a  trustee  or  other
fiduciary for a fiduciary  account may not be aggregated  with purchases made on
behalf of any other fiduciary or individual account.

     Shares purchased without an initial sales load in accordance with the sales
load schedule or pursuant to a Volume Discount,  Right of Accumulation or Letter
of Intent are subject to a CDSL of 1% on redemptions  within  eighteen months of
purchase.

     o VOLUME DISCOUNTS are provided if the total amount being invested in Class
A shares of the Series alone,  or in any  combination  of shares of the Seligman
Mutual Funds that are sold with an initial sales load,  reaches levels indicated
in the above sales load schedule.

     o THE RIGHT OF ACCUMULATION  allows an investor to combine the amount being
invested in shares of the other Seligman Mutual Funds sold with an initial sales
load with the total net asset  value of shares of those  Seligman  Mutual  Funds
already  owned that were sold with an initial sales load and the total net asset
value of shares of  Seligman  Cash  Management  Fund that were  acquired  by the
investor  through an exchange of shares of another Seligman Mutual Fund on which
there was an initial  sales load to determine  reduced sales loads in accordance
with the sales load  schedule.  An  investor  or a dealer  purchasing  shares on
behalf of any investor  must  indicate  that the investor has existing  accounts
when making investments or opening new accounts.

     o A LETTER OF INTENT  allows an investor to purchase  Class A shares of the
Series over a 13-month period at reduced initial sales loads, based on the total
amount of shares the investor intends to purchase plus the total net asset value
of shares of the other  Seligman  Mutual Funds already owned that were sold with
an initial  sales load and the total net asset value of shares of Seligman  Cash
Management  Fund that were  acquired  through an  exchange  of shares of another
Seligman  Mutual Fund on which there was an initial sales load. An investor or a
dealer  purchasing  Class A shares on behalf of any investor  must indicate that
the  investor  has  existing  accounts  when making  investments  or opening new
accounts. For more information concerning terms of Letters of Intent, see "Terms
and Conditions" on page 27.

     SPECIAL PROGRAMS.  The Series may sell Class A shares at net asset value to
present and retired directors,  trustees,  officers, employees and their spouses
(and  family  members  of the  foregoing)  of the  Fund,  the  other  investment
companies in the Seligman Group, the Manager and other companies affiliated with
the

                                       11
<PAGE>

Manager.  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 also may be made to
employee  benefit  and  thrift  plans  for such  persons  and to any  investment
advisory,  custodial, trust or other fiduciary account managed or advised by the
Manager or any affiliate.

     Class A  shares  also  may be  issued  without  an  initial  sales  load in
connection with the acquisition of cash and securities owned by other investment
companies and personal  holding  companies;  to any registered  unit  investment
trust  which is the  issuer  of  periodic  payment  plan  certificates,  the net
proceeds  of  which  are  invested  in  Series  shares;   to  separate  accounts
established  and  maintained  by an  insurance  company  which are  exempt  from
registration   under   Section   3(c)(11)  of  the  1940  Act;   to   registered
representatives  and  employees  (and their  spouses and minor  children) of any
dealer that has a sales  agreement  with SFSI; to  shareholders  of mutual funds
with  objectives  and policies  similar to the Series who  purchase  shares with
redemption  proceeds of such funds; to financial  institution trust departments;
to registered investment advisers exercising  discretionary investment authority
with  respect  to the  purchase  of Series  shares;  to  accounts  of  financial
institutions or broker/dealers that charge account management fees, provided the
Manager or one of its  affiliates  has entered into an agreement with respect to
such accounts;  pursuant to sponsored arrangements with organizations which make
recommendations to or permit group  solicitations of, its employees,  members or
participants  in  connection  with the purchase of shares of the Series;  and to
"eligible  employee benefit plans" which have at least (i) $500,000  invested in
the Seligman  Group of Mutual  Funds or (ii) 50 eligible  employees to whom such
plan is made  available.  "Eligible  employee  benefit  plan"  means any plan or
arrangement,  whether or not tax  qualified,  which provides for the purchase of
Series 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.  Employee  benefit plans eligible for
net asset value sales, as described  above,  will be subject to a CDSL of 1% for
terminations at the plan level only, on redemptions of shares  purchased  within
eighteen months prior to plan  termination.  Sales pursuant to the Merrill Lynch
MLII  multi-manager  401(k) product are available at net asset value and are not
subject to a CDSL.
    

     CLASS B SHARES.  Class B shares are sold without an initial  sales load but
are subject to a CDSL 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                                  CDSL

5 years or more but less than 6 years.................   1%
6 years or more.......................................   0%

     Class B shares are also subject to an annual  distribution  fee of .75% and
an annual  service fee of up to .25% of the average daily net asset value of the
Class B shares.  SFSI will make a 4% payment to dealers in respect of  purchases
of Class B shares. Approximately eight years after purchase, Class B shares will
convert  automatically to Class A shares, which are subject to an annual service
fee of .25% but no distribution  fee. 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 Series 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


                                       12
<PAGE>


will  be  tacked  onto  the  holding  period  of the  shares  acquired.  Class B
shareholders of the Series exercising the exchange privilege will continue to be
subject to the Series' CDSL  schedule if such  schedule is higher or longer than
the CDSL  schedule  relating  to the new Class B shares.  In  addition,  Class B
shares of the Series  acquired by exchange  will be subject to the Series'  CDSL
schedule if such schedule is higher or longer than the CDSL schedule relating to
the original Class B shares.

     CLASS D SHARES.  Class D shares are sold without an initial  sales load but
are  subject  to a CDSL if the shares are  redeemed  within one year,  an annual
distribution  fee of up to .75% and an annual  service fee of up to .25%, of the
average daily net asset value of the Class D shares. SFSI will make a 1% payment
to dealers in respect of  purchases  of Class D shares.  Unlike  Class B shares,
Class D shares do not automatically convert to Class A shares after eight years.

     CONTINGENT DEFERRED SALES LOAD. A CDSL will be imposed on any redemption of
Class B or Class D shares which were  purchased  during the  preceding six years
(for Class B shares) or twelve  months  (for Class D shares).  The amount of any
CDSL will be used by SFSI to defray  the  expense  of the  payment of 4% (in the
case of Class B  shares)  or 1% (in the case of  Class D  shares)  made by it to
Service  Organizations (as defined under  "Administration,  Shareholder Services
and Distribution  Plan") at the time of sale.  Pursuant to an agreement with FEP
Capital,  L.P.  ("FEP") to fund payments in respect of Class B shares,  SFSI has
agreed to sell any Class B CDSL to FEP.

   
     A CDSL of 1% will  also be  imposed  on any  redemption  of  Class A shares
purchased  during the preceding  eighteen months if such shares were acquired at
net asset value  pursuant to the sales load  schedule  provided  under  "Class A
Shares--Initial Sales Load." Employee benefit plans eligible for net asset value
sales as described above under "Special Programs" may be subject to a CDSL of 1%
for  terminations  at the plan level only, on  redemptions  of shares  purchased
within  eighteen  months prior to plan  termination.  No CDSL will be imposed on
shares  acquired  though the investment of dividends or  distributions  from any
Class A, Class B or Class D shares of mutual funds in the Seligman Group.
    

     To minimize the  application  of a CDSL to a  redemption,  shares  acquired
pursuant to the investment of dividends and distributions (which are not subject
to a CDSL) will be redeemed first;  followed by shares held for a period of time
longer than the  applicable  CDSL period.  Shares held for the longest period of
time within the applicable period will then be redeemed. Additionally, for those
shares  determined  to be subject to a CDSL,  the CDSL will be  assessed  on the
current net asset value or original purchase price, whichever is less.


     For example,  assume an investor purchased 100 Class D shares in January at
a price of $10.00 per share.  During the first year, 5 additional Class D shares
were acquired through investment of dividends and  distributions.  In January of
the following year, an additional 50 Class D shares were purchased at a price of
$12.00  per  share.  In March of that  year,  the  investor  chooses  to  redeem
$1,500.00 from the account which now holds 155 Class D shares with a total value
of  $1,898.75  ($12.25  per  share).  The  CDSL for  this  transaction  would be
calculated as follows:

Total shares to be redeemed
  (122.449 @ $12.25) as follows:              $1,500.00

     For  Federal  income tax  purposes,  the amount of the CDSL will reduce the
gain or increase the loss,  as the case may be, on the amount  recognized on the
redemption of shares.

     The CDSL will be waived or reduced in the following instances:

     (a) on redemptions  following the death or disability of a shareholder,  as
defined in section 72 (m)(7) of the Internal  Revenue  Code of 1986,  as amended
(the "Code");  (b) in connection with (i)  distributions  from retirement  plans
qualified  under section 401(a) of the Code when such  redemptions are necessary
to make distributions to plan participants  (such payments include,  but are not
limited to death,  disability,  retirement,  or  separation  of  service),  (ii)
distributions  from a custodial  account under section 403 (b)(7) of the Code or
an individual retirement account ("IRA") due to death, disability, or attainment
of age 591/2,  and (iii) a tax-free return of an excess  contribution to an IRA;
(c) in whole or in part, in  connection  with shares sold to current and retired
Trustees of the Fund; (d) in whole or in part, in connection with shares sold to
any state, county, or city or any  instrumentality,  department,  authority,  or
agency thereof,  which is prohibited by applicable investment laws from paying a
sales  load or  commission  in  connection  with the  purchase  of shares of any
registered  investment  management  company;  (e) pursuant to an automatic  cash
withdrawal  service;  and (f) in connection with the redemption of shares of the
Series if the Series is combined with another mutual fund in the Seligman Group,
or another similar reorganization transaction.

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

     SFSI may from time to time assist dealers by, among other things, providing
sales  literature  to, and holding  informational  programs  for the benefit of,
dealers'  registered  representatives.  Dealers may limit the  participation  of
registered  representatives  in such  informational  programs  by means of sales
incentive  programs  which may  require  the sale of minimum  dollar  amounts of
shares of the mutual funds in the Seligman Group. SFSI 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 Series  and/or  certain other funds
managed by the Manager  during a specified  period of time.  Such bonus or other
incentive may take the form of payment for travel expenses,  including  lodging,
incurred in connection with trips taken by qualifying registered representatives
and members of their families to places within or outside the United States. The
cost to SFSI of such  promotional  activities  and payments  shall be consistent
with the Rules of the National Association of Securities Dealers,  Inc., as then
in effect.

TELEPHONE TRANSACTIONS

     A shareholder with telephone transaction privileges,  AND THE SHAREHOLDER'S
BROKER/DEALER  REPRESENTATIVE,  will have the  ability to effect  the  following
transactions  via telephone:  (i) redemption of Series shares,  (ii) exchange of
Series  shares for shares of the same class of  another  Seligman  Mutual  Fund,
(iii) change of a dividend  and/or capital gain  distribution  option,  and (iv)
change of address. All telephone transactions are effected through Seligman Data
Corp. at (800) 221-2450.

     FOR INVESTORS WHO PURCHASE  SHARES BY COMPLETING  AND SUBMITTING AN ACCOUNT
APPLICATION  (EXCEPT THOSE ACCOUNTS REGISTERED AS TRUSTS (UNLESS THE TRUSTEE AND
SOLE BENEFICIARY ARE THE SAME PERSON),  CORPORATIONS OR GROUP RETIREMENT PLANS):
Unless an election is made otherwise on the Account  Application,  a shareholder
and the  shareholder's  broker/dealer  of record,  as  designated on the Account
Application, will automatically receive telephone services.

     FOR  INVESTORS  WHO  PURCHASE  SHARES  THROUGH A  BROKER/DEALER:  Telephone
services for a shareholder and the shareholder's  representative  may be elected
by

                                       14
<PAGE>

completing a supplemental  election application available from the broker/dealer
of record.

     FOR  ACCOUNTS  REGISTERED  AS IRAS:  Telephone  services  will include only
exchanges or address changes.

     FOR ACCOUNTS  REGISTERED AS TRUSTS (UNLESS THE TRUSTEE AND SOLE BENEFICIARY
ARE  THE  SAME  PERSON),  CORPORATIONS  OR  GROUP  RETIREMENT  PLANS:  Telephone
redemptions  are not permitted.  Additionally,  group  retirement  plans are not
permitted to change a dividend or gain distribution option.

     All Seligman  Mutual Funds with the same account  number (i.e.,  registered
exactly the same) as an existing  account,  including  any new fund in which the
shareholder invests in the future, will automatically include telephone services
if the existing account has telephone  services.  Telephone services may also be
elected at any time on a supplemental election application.

     For accounts registered jointly (such as joint tenancies, tenants in common
and community  property  registrations),  each owner, by accepting or requesting
telephone  services,  authorizes  each of the other  owners to effect  telephone
transactions on his or her behalf.

     During times of drastic  economic or market  changes,  a shareholder or the
shareholder's  representative may experience  difficulty in contacting  Seligman
Data Corp. to request a redemption  or exchange of Series shares via  telephone.
In these  circumstances,  the  shareholder or the  shareholder's  representative
should consider using other redemption or exchange procedures.  (See "Redemption
Of Shares"  below.) Use of these other  redemption or exchange  procedures  will
result in the  request  being  processed  at a later  time  than if a  telephone
transaction had been used, and the Series' net asset value may fluctuate  during
such periods.

   
     The Fund and  Seligman  Data Corp.  will employ  reasonable  procedures  to
confirm that  instructions  communicated  by telephone  are genuine.  These will
include:  recording all telephone calls requesting  account activity,  requiring
that the caller provide certain requested personal and/or account information at
the time of the call for the purpose of establishing the caller's identity,  and
sending a written  confirmation of redemptions,  exchanges or address changes to
the address of record each time activity is initiated by  telephone.  As long as
the Fund and Seligman Data Corp. follow  instructions  communicated by telephone
that  were  reasonably  believed  to be  genuine  at the time of their  receipt,
neither  they nor any of their  affiliates  will be  liable  for any loss to the
shareholder  caused by an  unauthorized  transaction.  In any instance where the
Fund or  Seligman  Data Corp.  is not  reasonably  satisfied  that  instructions
received  by  telephone  are  genuine,  the  requested  transaction  will not be
executed,  and neither they nor any of their  affiliates  will be liable for any
losses which may occur due to a delay in implementing  the  transaction.  If the
Fund or Seligman Data Corp. does not follow the procedures  described above, the
Fund or Seligman Data Corp. may be liable for any losses due to  unauthorized or
fraudulent  instructions.  Telephone  transactions  must be  effected  through a
representative  of Seligman Data Corp.,  i.e.,  requests may not be communicated
via Seligman Data Corp.'s automated telephone answering system. Shareholders, of
course,  may refuse or cancel  telephone  services.  Telephone  services  may be
terminated by a shareholder at any time by sending a written request to Seligman
Data  Corp.  TELEPHONE  SERVICES  MAY  NOT  BE  ESTABLISHED  BY A  SHAREHOLDER'S
BROKER/DEALER  WITHOUT THE WRITTEN  AUTHORIZATION  OF THE  SHAREHOLDER.  Written
acknowledgment  of the addition of telephone  services to an existing account or
termination of telephone services will be sent to the shareholder at the address
of record.
    

REDEMPTION OF SHARES

   
     A shareholder  may redeem  shares held in book credit form without  charge,
(except a CDSL,  if  applicable)  at any time by  SENDING A WRITTEN  REQUEST  to
Seligman Data Corp.,  P.O. Box 3947, New York, NY  10008-3947;  or if request is
being sent by overnight  delivery  service,  to 100 Park  Avenue,  New York, N Y
10017.  The  redemption  request must be signed by all persons in whose name the
shares are  registered.  A  shareholder  may redeem  shares that are not in book
credit form by  surrendering  certificates  in proper form to the same  address.
Certificates  should be sent by  registered  mail.  Share  certifi-

                                       15
<PAGE>

cates must be endorsed for transfer or  accompanied  by an endorsed  stock power
signed by all share  owners  exactly as their  name(s)  appear(s) on the account
registration.  The  shareholder's  letter of instruction or endorsed stock power
should specify the Series name, account number,  class of shares (A, B or D) and
the number of shares or dollar  amount to be  redeemed.  The Fund cannot  accept
conditional  redemption  requests  (i.e.,  requests to sell shares at a specific
price or on a future date). If the redemption  proceeds are (i) $50,000 or more,
(ii) to be paid to someone other than the  shareholder of record  (regardless of
the  amount)  or (iii)  to be  mailed  to  other  than  the  address  of  record
(regardless  of the amount),  the  signature(s)  of the  shareholder(s)  must be
guaranteed by an eligible financial institution  including,  but not limited to,
the following:  banks,  trust companies,  credit unions,  securities brokers and
dealers,  savings  and loan  associations  and  participants  in the  Securities
Transfer  Association  Medallion Program (STAMP),  the Stock Exchanges Medallion
Program  (SEMP)  and the New York Stock  Exchange  Medallion  Signature  Program
(MSP).  The Fund reserves the right to reject a signature  guarantee where it is
believed  that the Fund will be placed at risk by accepting  such  guarantee.  A
signature   guarantee  is  also   necessary  in  order  to  change  the  account
registration.  Notarization  by a notary public is not an  acceptable  signature
guarantee.  ADDITIONAL DOCUMENTATION MAY ALSO BE REQUIRED BY SELIGMAN DATA CORP.
IN THE EVENT OF A REDEMPTION BY A CORPORATION, EXECUTOR, ADMINISTRATOR, TRUSTEE,
CUSTODIAN OR RETIREMENT PLAN. FOR FURTHER INFORMATION WITH RESPECT TO REDEMPTION
REQUIREMENTS,  PLEASE CONTACT THE  SHAREHOLDER  SERVICES  DEPARTMENT OF SELIGMAN
DATA CORP. FOR ASSISTANCE.
    

     In the case of Class A shares  (except  for  shares  purchased  without  an
initial sales load due to the size of the purchase),  and in the case of Class B
shares  redeemed  after six years and Class D shares  redeemed after one year, a
shareholder  will  receive the net asset value per share next  determined  after
receipt  of a request in good  order.  If Class A shares  which  were  purchased
without an initial  sales load because the  purchase  amount was  $1,000,000  or
more,  are redeemed  within  eighteen  months of purchase,  a  shareholder  will
receive the net asset value per share next determined after receipt of a request
in good order, less a CDSL of 1% as described under "Purchase Of Shares--Class A
Shares--  Initial Sales Load" above.  If Class B shares are redeemed  within six
years of purchase, A shareholder will receive the net asset value per share next
determined after receipt of a request in good order, less the applicable CDSL as
described  under  "Purchase Of  Shares--Class B Shares" above. If Class D shares
are redeemed  within one year of purchase,  a  shareholder  will receive the net
asset value per share next determined  after receipt of a request in good order,
less a CDSL of 1% as described under "Purchase Of Shares--Class D Shares" above.

     A  shareholder  also may "sell"  shares to the Fund  through an  investment
dealer and, in that way, be certain, providing the order is timely, of receiving
the net asset  value  established  at the end of the day on which the  dealer is
given the repurchase order (less any applicable  CDSL). The Fund makes no charge
for this  transaction,  but the  dealer  may  charge a  service  fee.  "Sell" or
repurchase  orders  received from an  authorized  dealer before the close of the
NYSE and received by SFSI, the repurchase agent, before the close of business on
the same day will be executed at the net asset value per share  determined as of
the close of the NYSE on that day, less any applicable CDSL.  Repurchase  orders
received from authorized  dealers after the close of the NYSE or not received by
SFSI prior to the close of  business,  will be  executed  at the net asset value
determined  as of the  close  of the  NYSE on the  next  trading  day,  less any
applicable CDSL. Shares held in a "street name" account with a broker/dealer may
be sold to the Fund only through a broker/dealer.

     TELEPHONE  REDEMPTIONS.  Telephone redemptions of uncertificated shares may
be made once per day,  in an  amount of up to  $50,000  per  account.  Telephone
redemption  requests  received by Seligman Data Corp. at (800) 221-2450  between
8:30 a.m. and 4:00 p.m.  Eastern  time, on any business day will be processed as
of the close of business on that day.  Redemption requests by telephone will not
be accepted  within 30 days follow-

                                       16
<PAGE>

   
ing an address  change.  Keogh  Plans,  IRAs or other  retirement  plans are not
eligible for  telephone  redemptions.  The Fund reserves the right to suspend or
terminate the telephone  redemption service at any time without notice.


For more information  about telephone  redemptions and the  circumstances  under
which a shareholder may bear the risk of loss for a fraudulent transaction,  see
"Telephone Transactions" above.

     CHECK REDEMPTION SERVICE. The Check Redemption Service allows a shareholder
who owns or  purchases  shares in the  Series  worth  $25,000 or more to request
Seligman  Data  Corp.  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
Seligman Data Corp.  Shares for which  certificates have been issued will not be
available for  redemption  under this service.  Holders of Class A shares should
bear in mind that  check  redemptions  of Class A shares  acquired  at net asset
value due to the size of the purchase may be subject to a CDSL. Holders of Class
B shares may use this service  although check  redemptions of Class B shares may
be  subject  to a CDSL.  Holders  of Class D shares  may use this  service  with
respect to shares that have been held for at least one year.  Dividends continue
to be earned  through the date  preceding the date the check clears for payment.
Use of this  service is subject to Boston Safe  Deposit and Trust Co.  rules and
regulations  covering checking accounts.  Separate  checkbooks will be furnished
for each series of the Fund.

     There is no  charge  for use of  checks.  When  honoring  a check  that was
processed  for payment,  Boston Safe Deposit and Trust Co. will cause the Series
to redeem exactly enough full and fractional shares from an account to cover the
amount of the check  and any  applicable  CDSL.  If  shares  are owned  jointly,
redemption checks must be signed by all persons, unless otherwise elected on the
Account Application, in which case a single signature will be acceptable.
    

     In view of daily  fluctuations in share value,  the  shareholder  should be
certain  that the  amount of shares in the  account is  sufficient  to cover the
amount of checks written. If insufficient  shares are in the account,  the check
will be returned,  marked "insufficient  funds." THE FUND WILL NOT REDEEM SHARES
IN ONE SERIES TO COVER A CHECK  WRITTEN ON ANOTHER  SERIES.  SELIGMAN DATA CORP.
WILL CHARGE A $10.00  PROCESSING FEE FOR ANY CHECK  REDEMPTION DRAFT RETURNED AS
UNCOLLECTABLE. THIS CHARGE MAY BE DEDUCTED FROM THE SHAREHOLDER'S
ACCOUNT.

     Check redemption books cannot be reordered unless the shareholder's account
has  a  value  of  $25,000  or  more  and  the  Fund  has a  certified  Taxpayer
Identification Number on file.

     Cancelled checks will be returned to a shareholder under separate cover the
month after they clear.  The Check  Redemption  Service may be terminated at any
time by the Fund or Boston Safe Deposit and Trust Co. See "Terms and Conditions"
on page 27.

     GENERAL.  With respect to shares redeemed, a check for the proceeds will be
sent to the  shareholders'  address of record  within seven  calendar days after
acceptance  of the  redemption  order  and  will be made  payable  to all of the
registered  owners on the  account.  With respect to shares  repurchased  by the
Fund,  a check for the proceeds  will be sent to the  investment  dealer  within
seven calendar days after  acceptance of the  repurchase  order and will be made
payable to the investment dealer. The Fund will not permit redemptions of shares
with respect to shares purchased by check (unless certified) until Seligman Data
Corp.  receives  notice that the check has  cleared,  which may be up to 15 days
from the credit of the shares to the  shareholder's  account.  The proceeds of a
redemption or repurchase may be more or less than the shareholder's cost.

     The Fund reserves the right to redeem  shares owned by a shareholder  whose
investment in the Series has a value of less than a minimum amount  specified by
the Fund's  Trustees,  which is  presently  $500.  Shareholders  would be sent a
notice before such redemption is processed stating that the value of their

                                       17
<PAGE>

investment in the Series is less than the  specified  minimum and that they have
sixty days to make an additional investment.

   
     REINSTATEMENT  PRIVILEGE.  If a shareholder redeems Class A shares and then
decides  to  reinvest  them,  or to shift  the  investment  to one of the  other
Seligman Mutual Funds, the shareholder may, within 120 calendar days of the date
of  redemption,  use  all or any  part  of the  proceeds  of the  redemption  to
reinstate,  free of an initial sales load,  all or any part of the investment in
shares of the Series or in shares of one of the other Seligman  Mutual Funds. If
a  shareholder  redeems  shares and the  redemption  was subject to a CDSL,  the
shareholder  may  reinstate  the  investment  in shares of the same class of the
Series or any of the other Seligman Mutual Funds within 120 calendar days of the
date of redemption and receive a credit for the CDSL paid.  Such investment will
be  reinstated at the net asset value per share  established  as of the close of
the  NYSE on the day the  request  is  received.  Seligman  Data  Corp.  must be
informed that the purchase is a reinstated investment. REINSTATED SHARES MUST BE
REGISTERED  EXACTLY AND BE OF THE SAME CLASS AS THE SHARES PREVIOUSLY  REDEEMED;
AND THE MINIMUM INVESTMENT MUST BE MET AT THE TIME OF REINSTATEMENT.
    

     Generally,  exercise  of the  Reinstatement  Privilege  does not  alter the
Federal  income  tax status of any  capital  gain  realized  on a sale of Series
shares,  but to the extent  that any shares are sold at a loss and the  proceeds
are reinvested in shares of the same Series, some or all of the loss will not be
allowed  as  a  deduction,   depending  upon  the  percentage  of  the  proceeds
reinvested.


ADMINISTRATION, SHAREHOLDER SERVICES AND DISTRIBUTION PLAN

     Under the Series'  Administration,  Shareholder  Services and  Distribution
Plan (the  "Plan"),  the Series may pay to SFSI an  administration,  shareholder
services  and  distribution  fee in respect of the Series'  Class A, Class B and
Class D shares. Payments under the Plan may include, but are not limited to: (i)
compensation   to   securities   dealers  and  other   organizations   ("Service
Organizations")  for providing  distribution  assistance  with respect to assets
invested in the Series, (ii) compensation to Service Organizations for providing
administration, accounting and other shareholder services with respect to Series
shareholders,  and (iii)  otherwise  promoting the sale of shares of the Series,
including paying for the preparation of advertising and sales literature and the
printing and  distribution  of such  promotional  materials and  prospectuses to
prospective investors and defraying SFSI's costs incurred in connection with its
marketing efforts with respect to shares of the Series. The Manager, in its sole
discretion, may also make similar payments to SFSI from its own resources, which
may include the management fee that the Manager receives from the Series.

     Under the Plan, the Series reimburses SFSI for its expenses with respect to
Class A shares at an annual  rate of up to .25% of the  average  daily net asset
value of Class A  shares.  It is  expected  that  the  proceeds  from the fee in
respect  of  Class A  shares  will  be  used  primarily  to  compensate  Service
Organizations which enter into agreements with SFSI. Such Service  Organizations
will  receive  from  SFSI a  continuing  fee of up to .25% on an  annual  basis,
payable  quarterly,   of  the  average  daily  net  assets  of  Class  A  shares
attributable  to the  particular  Service  Organization  for providing  personal
service and/or the  maintenance of  shareholder  accounts.  The fee payable from
time to time is, within such limit, determined by the Trustees of the Fund.

     The Plan, as it relates to Class A shares,  was approved by the Trustees on
October 9, 1984 and was approved by the  shareholders of the Series on April 10,
1986. The Plan is reviewed by the Trustees  annually.  The total amount paid for
the year  ended  December  31,  1995 in respect  of the  Series'  Class A shares
pursuant to the Plan was equal to .21% of the Class A shares'  average daily net
assets.

     Under the Plan, the Series reimburses SFSI for its expenses with respect to
Class B and  Class D  shares  at an  annual  rate of up to 1% of the  respective
average  daily net asset value of the Class B and Class D shares.  Proceeds from
the Class B distribution fees

                                       18
<PAGE>

are  used to pay  Service  Organizations  a  continuing  fee of up to .25% on an
annual basis of the average daily net asset value of Class B shares attributable
to particular  Service  Organizations for providing  personal service and/or the
maintenance of shareholder  accounts and will also be used by SFSI to defray the
expense of the payment of 4% made by it to Service  Organizations at the time of
the sale of Class B shares. Proceeds from the Class D distribution fees are used
primarily to compensate Service  Organizations for  administration,  shareholder
services and distribution  assistance  (including a continuing fee of up to .25%
on an  annual  basis of the  average  daily  net  asset  value of Class D shares
attributable to particular Service  Organizations for providing personal service
and/or  maintenance of shareholder  accounts) and will initially be used by SFSI
to defray the expense of the  payment of 1% made by it to Service  Organizations
at the time of sale of Class D shares.  The amounts  expended by SFSI in any one
year upon the  initial  purchase  of Class B and Class D shares  may  exceed the
amounts received by it from Plan payments retained.  Expenses of administration,
shareholder  services  and  distribution  of Class B and  Class D shares  in one
fiscal  year  may be paid  from  Class B and  Class D Plan  fees,  respectively,
received in any other fiscal year.

     The Plan, as it relates to Class B shares,  was approved by the Trustees on
September 19, 1996.  The Plan,  as it relates to Class D shares,  was amended by
the Trustees of the Fund on July 15, 1993.  The Plan is reviewed by the Trustees
annually.  The total  amount  paid for the year ended  December  31, 1995 by the
Series'  Class D shares  pursuant  to the Plan was 1% per  annum of the  average
daily net assets of the Class D shares.

     Seligman Services,  Inc. ("SSI"), an affiliate of the Manager, is a limited
purpose broker/dealer.  SSI acts as broker/dealer of record for most shareholder
accounts that do not have a designated  broker/dealer  of record,  including all
such  shareholder  accounts  established  after  April 1, 1995 and will  receive
compensation  for  providing  personal  service and account  maintenance  to its
accounts of record.

EXCHANGE PRIVILEGE

     A  shareholder  of the Series may,  without  charge,  exchange at net asset
value any part or all of an  investment  in the  Series  for shares of the other
series  of the  Fund or for  shares  of any of the  other  mutual  funds  in the
Seligman  Group.  Exchanges  may  be  made  by  mail,  or by  telephone  if  the
shareholder has telephone services.

     Class A,  Class B and  Class D shares  may be  exchanged  only for Class A,
Class B and Class D  shares,  respectively,  of the other  series of the Fund or
another  mutual fund in the  Seligman  Group on the basis of relative  net asset
value.

     If shares  that are subject to a CDSL are  exchanged  for shares of another
Seligman  Mutual  Fund,  then for  purposes of  assessing  the CDSL payable upon
disposition  of the exchanged  shares,  the  applicable  holding period shall be
reduced by the holding period of the original shares.

     Class B shareholders of the Series  exercising the exchange  privilege will
continue to be subject to the Series' CDSL  schedule if such  schedule is higher
or  longer  than  the CDSL  schedule  relating  to the new  Class B  shares.  In
addition, Class B shares of the Series acquired through exchange will be subject
to the Series' CDSL  schedule if such schedule is higher or longer than the CDSL
schedule  relating to the Class B shares of the Fund from which the exchange has
been made.

     The Seligman Mutual Funds available under the Exchange Privilege are:

      o SELIGMAN  CAPITAL FUND,  INC.  seeks  aggressive  capital  appreciation.

     All  permitted  exchanges  will be based  on the net  asset  values  of the
respective  funds  determined  at the close of the NYSE on that  day.  Telephone
requests for exchanges received between 8:30 a.m. and 4:00 p.m. Eastern time, on
any business day, by Seligman Data Corp. at (800) 221-2450, will be processed as
of the close of business on that day. The  registration of an account into which
an exchange is made must be  identical to the  registration  of the account from
which shares are  exchanged.  When  establishing a new account by an exchange of
shares,  the shares  being  exchanged  must have a value of at least the minimum
initial investment  required by the mutual fund into which the exchange is being
made. THE METHOD OF RECEIVING DISTRIBUTIONS, UNLESS OTHERWISE INDICATED, WILL BE
CARRIED  OVER TO THE NEW  FUND  ACCOUNT,  AS WILL  TELEPHONE  SERVICES.  ACCOUNT
SERVICES, SUCH AS INVEST-A-CHECK(R) SERVICE, DIRECTED DIVIDENDS,  AUTOMATIC CASH
WITHDRAWAL  SERVICE AND CHECK WRITING  PRIVILEGE WILL NOT BE CARRIED OVER TO THE
NEW FUND ACCOUNT  UNLESS  SPECIFICALLY  REQUESTED AND PERMITTED BY THE NEW FUND.
Exchange  orders may be placed to effect an  exchange  of a  specific  number of
shares,  an exchange of shares equal to a specific  dollar amount or an exchange
of all shares held.  Shares for which  certificates  have been issued may not be
exchanged  via  telephone  and may be  exchanged  only upon receipt of a written
exchange request together with certificates  representing shares to be exchanged
in proper form.

     The Exchange  Privilege via mail is generally  applicable to investments in
group retirement  plans,  although some restrictions may apply. The terms of the
exchange offers described herein may be modified at any time;

                                       20
<PAGE>

and not all of the mutual funds in the Seligman Group are available to residents
of all states.  Before making any  exchange,  a  shareholder  should  contact an
authorized  investment  dealer or Seligman Data Corp. to obtain  prospectuses of
any of the Seligman Mutual Funds.

     A broker/dealer  representative  of record will be able to effect exchanges
on behalf of a shareholder only if the shareholder has telephone services or the
broker/dealer has entered into a Telephone  Exchange Agreement with SFSI wherein
the  broker/dealer  must agree to indemnify  SFSI and the Seligman  Mutual Funds
from any loss or liability  incurred as a result of the  acceptance of telephone
exchange orders.

     Written  confirmation of all exchanges will be forwarded to the shareholder
to whom the exchanged shares are registered and a duplicate confirmation will be
sent to the  broker/dealer  of record  listed on the account.  SFSI reserves the
right to reject any telephone exchange request.  Any rejected telephone exchange
order may be processed by mail. For more  information  about telephone  exchange
privileges,  which  unless  objected  to,  are  assigned  to  most  shareholders
automatically,  and the circumstances under which shareholders may bear the risk
of loss for a fraudulent transaction, see "Telephone Transactions" above.

     Exchanges  of shares are sales and may result in a gain or loss for Federal
income tax purposes.


FURTHER INFORMATION ABOUT TRANSACTIONS IN THE SERIES

     Because excessive trading (including  short-term,  "market timing" trading)
can hurt the series' performance,  the fund may refuse any exchange (1) from any
shareholder  account from which there have been two  exchanges in the  preceding
three month period,  or (2) where the exchanged shares equal in value the lesser
of  $1,000,000  or 1% of the series'  net  assets.  The fund may also refuse any
exchange or purchase order from any  shareholder  account if the  shareholder or
the  shareholder's  broker/dealer  has been  advised that  previous  patterns of
purchases and redemptions or exchanges have been considered excessive.  Accounts
under common  ownership or control,  including  those with the same  taxpayer id
number and those  administered  so as to redeem or  purchase  shares  based upon
certain predetermined market indicators, will be considered one account for this
purpose.  Additionally,  the fund reserves the right to refuse any order for the
purchase of shares.


DIVIDENDS AND DISTRIBUTIONS

     The Series' net investment income is distributed to shareholders monthly in
the form of additional shares, unless the shareholder elects otherwise. Payments
vary in amount depending on income received from the Series' investments and the
costs of operations. Shares begin earning dividends on the day on which the Fund
receives  payment.  Shares continue to earn dividends through the date preceding
the date they are redeemed.

     The Series  distributes  substantially all of any taxable net long-term and
short-term gain realized on investments to  shareholders  at least annually.  In
determining  amounts  of  capital  gains to be  distributed,  any  capital  loss
carryforwards from prior years will offset capital gains. For Federal income tax
purposes,  the Series had a capital loss carryforward as of December 31, 1995 of
$16,299,262 (including $2,420,836 transferred from the Seligman Secured Mortgage
Income Series), of which $1,652,560 expires in 1996, $2,286,339 expires in 1997,
$3,877,110  expires in 1998,  $12,467 expires in 2001 and $8,470,786  expires in
2002.  Accordingly,  the Series may not distribute  capital gains (short-term or
long-term) to  shareholders  until net gains have been realized in excess of the
capital loss carryforward.

     Shareholders   may  elect:   (1)  to  receive  both   dividends   and  gain
distributions in shares; (2) to receive dividends in cash and gain distributions
in shares;  (3) to receive both dividends and gain  distributions  in cash. Cash
dividends  and gain  distributions  are paid by check.  In the case of prototype
retirement plans,  dividends and gain

                                       21
<PAGE>

distributions  are reinvested in additional  shares.  Unless another election is
made,  dividends and capital gain  distributions will be credited to shareholder
accounts  in  additional  shares.  Shares  acquired  through a dividend  or gain
distribution  and  credited  to a  shareholder's  account  are not subject to an
initial sales load or a CDSL.  Dividends and gain  distributions  paid in shares
are  invested on the payable  date using the net asset value of the  ex-dividend
date.  Shareholders  may elect to change their  dividend  and gain  distribution
options by writing  Seligman  Data Corp.  at the address  listed  below.  If the
shareholder has telephone  services,  changes may also be telephoned to Seligman
Data  Corp.  between  8:30  a.m.  and 6:00 p.m.  Eastern  time,  by  either  the
shareholder or the broker/dealer of record on the account. For information about
telephone  services,  see  "Telephone  Transactions."  These  elections  must be
received  by  Seligman  Data Corp.  before the record  date for the  dividend or
distribution in order to be effective for such dividend or distribution.

     The per share  dividends from net investment  income on Class B and Class D
shares will be lower than the per share  dividends on Class A shares as a result
of the higher  distribution  fees applicable with respect to Class B and Class D
shares.  Per share dividends of the three classes may also differ as a result of
differing  class expenses.  Distributions  of net capital gains, if any, will be
paid in the same amount for Class A, Class B and Class D shares.  See  "Purchase
Of Shares--Valuation."

   
     Shareholders  exchanging  shares of one  mutual  fund for shares of another
mutual fund in the Seligman  Group will continue to receive  dividends and gains
as elected prior to such exchange unless otherwise specified.  In the event that
a shareholder redeems,  transfers, or exchanges all shares in an account between
the  record  date and the  payable  date,  the  value of any  dividends  or gain
distributions declared will be paid in cash regardless of the existing election.
    


FEDERAL INCOME TAXES

     The Series intends to continue to qualify as a regulated investment company
under the Code.  For each year so  qualified,  the Series 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.

     Dividends from net investment income and distributions  from net short-term
capital  gains are  taxable  as  ordinary  income to the  shareholders,  whether
received in cash or reinvested in additional  shares,  and are,  generally,  not
eligible for the dividends received deduction for corporations.

     Distributions  of net  capital  gain,  i.e.,  the  excess of net  long-term
capital gains over any net short-term  losses,  are taxable as long-term capital
gain, whether received in cash or invested in additional  shares,  regardless of
how long shares have been held by the shareholders;  such  distributions are not
eligible for the dividends received deduction allowed to corporate shareholders.
As noted above, the Series must exhaust its capital loss carry forward before it
may make capital gain distributions to shareholders.

     Any gain or loss realized upon a sale or redemption of shares in the Series
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.  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 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  Series  if,  within a period
beginning 30 days before the date of such sale or disposition and ending 30 days
after such date,  the holder  acquires (such as through  dividend  reinvestment)
securities that are substantially identical to the shares of the Series.

     In  determining  gain or loss on  shares  of the  Series  that  are sold or
exchanged within 90 days after acquisition,  a shareholder generally will not be
permitted to

                                       22
<PAGE>

include in the tax basis  attributable to such shares the sales load incurred in
acquiring  such shares to the extent of any  subsequent  reduction  in the sales
load by reason of the Exchange or Reinstatement Privilege offered by the Series.
Any sales load not taken into  account  in  determining  the tax basis of shares
sold or  exchanged  within  90 days  after  acquisition  will  be  added  to the
shareholder's  tax basis in the shares  acquired  pursuant  to the  Exchange  or
Reinstatement Privilege.

     The Series 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. 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 Series 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 advisers  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 U.S.  TREASURY A PORTION OF  DISTRIBUTIONS
AND OTHER REPORTABLE PAYMENTS TO THE SHAREHOLDER. THE RATE OF BACKUP WITHHOLDING
IS 31%. SHAREHOLDERS SHOULD BE AWARE THAT, UNDER REGULATIONS  PROMULGATED BY THE
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 GAINS DISTRIBUTIONS.  THE FUND ALSO RESERVES
THE  RIGHT TO CLOSE  ANY  ACCOUNT  WHICH  DOES  NOT  HAVE A  CERTIFIED  TAXPAYER
IDENTIFICATION NUMBER.

ADVERTISING THE SERIES' PERFORMANCE

     From time to time the Series  advertises  its "yield,"  "total  return" and
"average annual total return," each of which are calculated separately for Class
A, Class B and Class D shares.  THESE FIGURES ARE BASED ON  HISTORICAL  EARNINGS
AND ARE NOT INTENDED TO INDICATE FUTURE  PERFORMANCE.  The "yield" of a class of
the Series refers to the income  generated by an investment in that class over a
30-day period.  This income is then  "annualized." That is, the amount of income
generated by the investment during that 30-day period is assumed to be generated
each  30-day  period  for twelve  periods  and is shown as a  percentage  of the
investment. The income earned on the investment is also assumed to be reinvested
at the  end of the  sixth  30-day  period.  The  "total  return"  shows  what an
investment in shares of a class of the Series would have earned over a specified
period  of time (for  example,  one,  five and ten years or from the  inception)
assuming the payment of the maximum sales load, if any, when the  investment was
first  made  and  that  all  distributions  and  dividends  by that  class  were
reinvested  on the  reinvestment  dates during the period.  The "average  annual
total return" is the annual rate required for the initial payment to grow to the
amount which would be received at the end of the specified period (one, five and
ten years or from the  inception);  i.e.,  the average  annual  compound rate of
return.  Total  return and average  annual  total  return may also be  presented
without the effect of the initial sales load or CDSL, as applicable.

     From time to time,  reference  may be made in  advertising  or  promotional
material to performance information, including mutual fund rankings, prepared by
Lipper Analytical Service,  Inc.  ("Lipper"),  an independent  reporting service
which monitors the  performance of mutual funds. In calculating the total return
of the Series' Class A, Class B and Class D shares,  the Lipper analysis assumes
investment  of all  dividends  and  distributions  paid but  does not take  into
account  applicable sales loads. The Series may also refer in  advertisements or
in other promotional material to articles, comments, listings and columns in the
financial  press  pertaining  to  the  Series'  performance.  Examples  of  such
financial  and  other  press  publications  include  BARRON'S,   BUSINESS  WEEK,
CDA/WEISENBERGER  MUTUAL FUNDS  INVESTMENT  REPORT,  CHRISTIAN  SCIENCE MONITOR,
FINANCIAL  PLANNING,   FINANCIAL  TIMES,   FINANCIAL  WORLD,  FORBES,   FORTUNE,

ORGANIZATION AND CAPITALIZATION

     The Fund is a diversified, open-end management investment company organized
under the laws of the  Commonwealth of  Massachusetts  by a Declaration of Trust
dated July 27, 1984.  The  Declaration of Trust permits the Trustees to issue an
unlimited number of full and fractional shares of beneficial interest, $.001 par
value. The Trustees also have the power to create additional series of shares.

     Shares of  beneficial  interest of two series have been  authorized,  which
shares  of  beneficial  interest  constitute  interests  in the  Series  and the
Seligman High-Yield Bond Series. Shares of beneficial interest of the Series and
the Seligman  High-Yield  Bond Series are divided into three  classes  (Class A,
Class B and Class D). Each share of  beneficial  interest of the Series' and the
Seligman  High-Yield  Bond Series'  respective  classes 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

law. The Fund has adopted a plan (the `Multiclass  Plan") pursuant to Rule 18f-3
under the 1990 Act  permitting  the  issuance  and sale of  multiple  classes of
shares of beneficial interest.  In accordance with the Declaration of Trust, the
Trustees  may  authorize  the  creation  of  additional  classes  of  shares  of
beneficial interest with such characteristics as are permitted by the Multiclass
Plan and Rule  18f-3.  The 1940 Act  requires  that  where  more  than one class
exists, each class must be preferred over all other classes in respect of assets
specifically  allocated to such class.  Shares entitle their holders to one vote
per share.  Shares have  noncumulative  voting rights, do not have preemptive or
subscription rights and are transferable. It is the intention of the Fund not to
hold Annual Meetings of Shareholders.  The Trustees may call Special Meetings of
Shareholders  for action by shareholder  vote as may be required by the 1940 Act
or Declaration of Trust.  Pursuant to the 1940 Act, shareholders have to approve
the adoption of any management  contract,  distribution  plan and any changes in
fundamental  investment  policies.  Shareholders  also  have the right to call a
meeting of shareholders  for the purpose of voting on the removal of one or more
Trustees.  Such  removal can be effected  upon the action of  two-thirds  of the
outstanding shares of the Fund.

                              TERMS AND CONDITIONS

                           GENERAL ACCOUNT INFORMATION

    Investments will be made in as many shares, including fractions to the third
decimal place,  as can be purchased at the net asset value plus a sales load, if
applicable,  at the close of business on the day payment is received. If a check
received  in payment  of a  purchase  of shares is  dishonored  for any  reason,
Seligman  Data Corp.  may cancel the  purchase  and may also  redeem  additional
shares,  if any, held in the  shareholder's  account in an amount  sufficient to
reimburse  the Fund for any loss it may have incurred and charge a $10.00 return
check fee.  Shareholders  will receive  dividends from investment income and any
distributions  from gain realized on  investments in shares or in cash according
to the option  elected.  Dividend  and gain  options may be changed by notifying
Seligman Data Corp. These option changes must be received by Seligman Data Corp.
before the record date for the dividend or distribution to be effective for such
dividend  or  distribution.   Stock  certificates  will  not  be  issued  unless
requested. Replacement stock certificates will be subject to a surety fee.


                            INVEST-A-CHECK(R) SERVICE

    The  Invest-A-Check(R)  Service  is  available  to  all  shareholders.   The
application is subject to acceptance by the shareholder's banK and Seligman Data
Corp. The electronic funds transfer ("ACH debit") or preauthorized  check in the
amount specified will be drawn  automatically on the  shareholder's  bank on the
fifth day (unless  otherwise  specified) of each month (or on the prior business
day if such  day of the  month  falls  on a  weekend  or  holiday)  in  which an
investment is scheduled and invested at the public  offering  price at the close
of business on the same date. After the initial investment,  the value of shares
held in the  shareholder's  account  must  equal  not less  than  two  regularly
scheduled  investments.  If a check is not honored by the shareholder's bank, or
if  the  value  of  shares  held  falls   below  the   required   minimum,   the
Invest-A-Check(R)  Service  may be  suspended.  In the event that a check or ACH
debit iS  returned  as  uncollectable,  Seligman  Data  Corp.  will  cancel  the
purchase,  redeem  shares  held  in the  shareholder's  account  for  an  amount
sufficient  to reimburse the Fund for any loss it may have incurred as a result,
and  charge  a $10.00  return  check  fee.  This  fee may be  deducted  from the
shareholder's  account.  The  Invest-A-Check(R)  Service may be reinstated  upon
written request  indicating  thaT the cause of interruption  has been corrected.
The Invest-A-Check(R) Service may be terminated by the shareholder's or Seligman
DatA Corp. at any time by written  notice.  The  shareholder  agrees to hold the
Fund and its agents free from all  liability  which may result from acts done in
good  faith  and  pursuant  to  these  terms.   Instructions   for  establishing
Invest-A-Check(R)  Service are given on thE Account Application.  In the event a
shareholder  exchanges  all of the  shares  from  one  Seligman  Mutual  Fund to
another, the Invest-A-Check(R) Service will be terminated in the Seligman Mutual
Fund  that  was  closed  as a  result  of the  exchange  of all  shares  anD the
shareholder  must  re-apply  for the  Invest-A-Check(R)  Service in the Seligman
Mutual  Fund  into  which  the  exchange  was  made.  In thE  event of a partial
exchange, the Invest-A-Check(R) Service will be continued,  subject to the above
conditions,  in the  Seligman  MutuaL  Fund from  which the  exchange  was made.
Accounts established in conjunction with the  Invest-A-Check(R)  Service must be
accompanied  by A minimum  initial  investment  of $100 in  connection  with the
monthly  investment  option or $250 in connection with the quarterly  investment
option.  If a  shareholder  uses the  Invest-A-Check(R)  Service  to make an IRA
investment,  the purchase will be credited as A current year contribution.  If a
shareholder  uses the  Invest-A-Check(R)  to make an  investment in a pension or
profit  sharing  plan,  thE purchase will be credited as a current year employer
contribution.
                        AUTOMATIC CASH WITHDRAWAL SERVICE

    The Automatic Cash Withdrawal  Service is available to Class A shareholders,
to Class B  shareholders  and to Class D  shareholders  with  respect to Class D
shares held for one year or more.  A  sufficient  number of full and  fractional
shares will be redeemed to provide the amount required for a scheduled  payment.
Redemptions  will be made at the net asset value at the close of business on the
specific  day  designated  by the  shareholder  of each  month  (or on the prior
business day if the day specified  falls on a weekend or holiday),  less, in the
case of Class B shares,  any applicable CDSL.  Automatic  withdrawals of Class A
shares which were  purchased at net asset value because the purchase  amount was
$1,000,000  or more  will be  subject  to a CDSL if made  within  18  months  of
purchase  of such  shares.  A  shareholder  may change  the amount of  scheduled
payments or may suspend  payments by written  notice to Seligman  Data Corp.  at
least ten days prior to the effective date of such a change or  suspension.  The
Service may be terminated by the  shareholder or Seligman Data Corp. at any time
by written notice.  It will be terminated upon proper  notification of the death
or legal incapacity of the shareholder. This Service is considered terminated in
the event a  withdrawal  of  shares,  other  than to make  scheduled  withdrawal
payments,  reduces the value of shares remaining on deposit to less than $5,000.
Continued  payments  in excess of  dividend  income  invested  will  reduce  and
ultimately exhaust capital. Withdrawals,  concurrent with purchases of shares of
this or any other investment  company,  will be  disadvantageous  because of the
payment of duplicative sales loads, if applicable.  For this reason,  additional
purchases of Series shares are  discouraged  when the  Withdrawal  Service is in
effect.

                     LETTER OF INTENT -- CLASS A SHARES ONLY

    Seligman Financial Services,  Inc. will hold in escrow shares equal to 5% of
the minimum  purchase  amount  specified.  Dividends  and  distributions  on the
escrowed shares will be paid to the shareholder or credited to the shareholder's
account.   Upon  completion  of  the  specified   minimum  purchase  within  the
thirteen-month  period,  all shares  held in escrow will be  deposited  into the
shareholder's account or delivered to the shareholder. A shareholder may include
toward the  completion  of a Letter of Intent the total asset value of shares of
the Seligman Mutual Funds on which an initial sales load was paid as of the date
of the Letter.  If the total amount  invested within the  thirteen-month  period
does not equal or exceed the specified minimum purchase, the shareholder will be
requested  to pay the  difference  between the amount of the sales load paid and
the amount of the sales load  applicable to the total  purchase made. If, within
20 days following the mailing of a written request, the shareholder has not paid
this  additional  sales load to Seligman  Financial  Services  Inc.,  sufficient
escrowed  shares will be  redeemed  for  payment of the  additional  sales load.
Shares  remaining  in  escrow  after  this  payment  will  be  released  to  the
shareholder's account. The intended purchase amount may be increased at any time
during  the  thirteen-month  period by filing a revised  Agreement  for the same
period,  provided that a Dealer furnishes  evidence that an amount  representing
the reduction in sales load under the new Agreement, which becomes applicable on
purchases  already  made under the original  Agreement,  will be refunded to the
Fund and that the required  additional  escrowed shares will be purchased by the
shareholder.

    Shares of Seligman Cash Management Fund, Inc. which have been acquired by an
exchange of shares of another  Seligman Mutual Fund on which there is an initial
sales load may be taken into account in  completing  a Letter of Intent,  or for
Right of  Accumulation.  However,  shares of the Seligman Cash  Management  Fund
which have been  purchased  directly may not be used for purposes of determining
reduced sales loads on additional purchases of the other Seligman Mutual Funds.


                            CHECK REDEMPTION SERVICE

   
    The Check Redemption Service is available to Class A shareholders,  to Class
B shareholders  and to Class D shareholders  with respect to Class D shares held
for one year or more. For Class A shares which were purchased at net asset value
because the purchase amount was $1,000,000 or more, check redemptions  within 18
months of purchase may be subject to a CDSL. Check redemptions of Class B shares
also  may be  subject  to a CDSL.  If  shares  are  held  in  joint  names,  all
shareholders must sign the Check Redemption section of the Account  Application.
All checks will require all  signatures  unless a lesser  number is indicated in
the Check Redemption  section.  Accounts in the names of  corporations,  trusts,
partnerships,  etc. must list all  authorized  signatories.  In all cases,  each
signature guarantees the genuineness of the other signatures.  Checks may not be
drawn for less than $500.

    The shareholder authorizes Boston Safe Deposit and Trust Co. to honor checks
drawn by the shareholder on the account of Seligman U.S.  Government  Securities
Series and to effect a redemption of sufficient shares in the shareholder's Fund
account to cover payment of the check and any applicable  CDSL. The  shareholder
understands  that  shares  in one  series  cannot be  redeemed  to cover a check
written on another series.
    


    Boston  Safe  Deposit  and  Trust  Co.  shall  be  liable  only  for its own
negligence.  The Fund will not be liable for any loss,  expense or cost  arising
out of check  redemptions.  The Fund  reserves  the right to  change,  modify or
terminate  this service at any time upon  notification  mailed to the address of
record of the shareholder(s).

    Seligman  Data  Corp.  will  charge a $10.00  processing  fee for any  check
redemption draft returned as uncollectable. This charge may be deducted from the
account  against  which the check was  drawn.  No  redemption  proceeds  will be
remitted to a  shareholder  with respect to shares  purchased  by check  (unless
certified) until Seligman Data Corp.  receives notice that the check has cleared
which may be up to 15 days from the  credit of the  shares to the  shareholder's
account.
                                                                            1/97

         This Statement of Additional  Information  expands upon and supplements
the information  contained in the current Prospectus for each series of Seligman
High  Income Fund Series  (the  "Fund"),  dated April 22, 1996 for the  Seligman
High-Yield  Bond Series  ("High-Yield  Bond Series") and January 1, 1997 for the
Seligman  U.S.  Government   Securities  Series  ("U.S.   Government  Securities
Series").  It should be read in conjunction with the Prospectuses,  which may be
obtained  by  writing  or calling  the Fund at the above  address  or  telephone
numbers.  This  Statement of  Additional  Information,  although not in itself a
Prospectus, is incorporated by reference into each Prospectus in its entirety.

         Each Series of the Fund offers three classes of shares.  Class A shares
may be purchased  at net asset value plus an initial  sales load of up to 4.75%.
Class A shares  purchased in an amount of $1,000,000 or more are sold without an
initial sales load but are subject to a contingent  deferred sales load ("CDSL")
of 1% (of the current net asset value or the original purchase price,  whichever
is less) if such  shares  are  redeemed  within 18 months of  purchase.  Class B
shares  may be  purchased  at net asset  value  and are  subject  to a CDSL,  if
applicable,  in the  following  amount (as a percentage of the current net asset
value or the original  purchase price,  whichever is less, if redemption  occurs
within the indicated number of years of purchase of such shares: 5% (less than 1
year),  4% (1 but less  than 2 years),  3% (2 but less than 4 years),  2% (4 but
less than 5 years), 1% (5 but less than 6 years) and 0% (6 or more years). Class
B shares automatically convert to class A shares after approximately eight years
resulting in lower  ongoing  fees.  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. Class
D shares may be purchased at net asset value and are subject to a CDSL of 1% (of
the current net asset value or the original  purchase price,  whichever is less)
if redeemed within one year of purchase.

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

                    INVESTMENT OBJECTIVES, POLICIES AND RISKS

      The  investment  objective of each Series is a fundamental  policy and may
not be changed by the  Trustees  of the Fund  without  the vote of a majority of
such Series'  outstanding voting securities.  The objective of each Series is as
follows:

      The U.S.  Government  Securities  Series  seeks to  produce  high  current
income.  To  achieve  its  objective,  the  Series  invests  primarily  in  debt
obligations  issued or  guaranteed  by the U.S.  Government  or its  agencies or
instrumentalities and backed by the full faith and credit of the U.S. Government
which have  maturities  of greater  than one year at the date of purchase by the
Series.

      The High-Yield Bond Series seeks to produce  maximum  current  income.  To
achieve its objective, the Series invests primarily in high-yielding,  high-risk
corporate  bonds and notes,  which  generally are unrated or carry lower ratings
(Baa or lower by Moody's Investors Service,  Inc. ("Moody's") or BBB or lower by
Standard & Poor's Corporation  ("S&P")) than those assigned by S&P or Moody's to
investment grade bonds and notes. Except for temporary  defensive purposes,  the
Series  will  invest at least 80% of the value of its  assets in  high-yielding,
income-producing  corporate  bonds and  notes.  Investments  other  than in such
corporate  bonds  will be in  short-term  money  market  instruments,  including
certificates of deposit,  commercial  paper,  securities  issued,  guaranteed or
insured by the U.S. Government,  its agencies and  instrumentalities,  and other
income  producing cash items. The High-Yield Bond Series may invest up to 10% of
its total assets in debt 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 U.S.  company,  and foreign companies may not be subject to
reporting  standards and  requirements  comparable  to those  applicable to U.S.
companies.  Foreign debt  securities  and their  markets may not be as liquid as
U.S.  securities  and their markets.  Securities and some foreign  companies may
involve  greater  market risk than  securities  of U.S.  companies,  and foreign
brokerage  commissions and custody fees are generally  higher than in the United
States.  Investments  in foreign  debt  securities  may also be subject to local
economic or  political  risks,  such as  political  instability  of some foreign
governments and the possibility of nationalization of issuers.

      The following information regarding the investment policies of each Series
supplements the information contained in each Series' Prospectus.

LENDING OF SECURITIES.  Each Series of the Fund may lend portfolio securities to
certain institutional borrowers of securities and may invest the cash collateral
and obtain  additional  income or receive an agreed upon amount of interest from
the  borrower.  Loans  will  generally  be  short-term.  Loans  are  subject  to
termination  at the option of the Series or the  borrower.  Each  Series 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.  Loaned  securities  may not be
returned by a borrower;  however,  a borrower must maintain with the Series from
which it has borrowed securities,  cash, or equivalent  collateral,  equal to at
least 100% of the market value of the securities borrowed.

REPURCHASE  AGREEMENTS.  Each  Series  of the Fund  may  enter  into  repurchase
agreements with commercial banks and with  broker/dealers to invest cash for the
short-term.  A  repurchase  agreement  is an  agreement  under  which the Series
acquires a money  market  instrument,  generally a U.S.  Government  obligation,
qualified for purchase by the Series,  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 Series 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. As a matter of
fundamental  policy, a Series will not enter into repurchase  agreements of more
than one week's  duration if more than 10% of its total assets would be invested
in such agreements and in "restricted" and other illiquid securities.

WHEN-ISSUED  SECURITIES.  Each Series may purchase  securities  on a when-issued
basis,  in which case  delivery and payment  normally  take place within 45 days
after the date of the  commitment to purchase.  The payment  obligation  and the
interest rate that will be received on the securities are each fixed at the time
the buyer  enters  into the  commitment.  Although a Series  will only  purchase
securities on a when-issued  basis with the intention of actually  acquiring the
securities,  the Series may sell these securities  before the settlement date if
it is deemed advisable.

      Securities  purchased on a when-issued  basis and the  securities  held in
each  Series are  subject to changes  in market  value  based upon the  public's
perception  of  the  creditworthiness  of  the  issuer  and  changes,   real  or
anticipated,  in the level of interest  rates  (which will  generally  result in

                                      -2-


<PAGE>


similar changes in value,  i.e., both  experiencing  appreciation  when interest
rates decline and  depreciation  when interest  rates rise).  Therefore,  to the
extent a Series  remains  substantially  fully invested at the same time that it
has  purchased  securities  on a  when-issued  basis,  there  will be a  greater
possibility  that the market  value of the  Series'  assets  will vary more than
otherwise.  Purchasing a security on a when-issued basis can involve a risk that
the yields  available in the market when the delivery  takes place may be higher
than those obtained on the security so purchased.

      A  separate  account of each of the  Series  consisting  of cash or liquid
high-grade  debt securities  equal to the amount of the when-issued  commitments
will be established with Investors Fiduciary Trust Company, the Fund's portfolio
securities custodian, and marked to market daily, with additional cash or liquid
high grade debt securities added when necessary.  When the time comes to pay for
when-issued  securities,  each Series will meet its respective  obligations from
then available cash flow, sale of securities held in the separate account,  sale
of other  securities or,  although they would not normally expect to do so, from
the  sale of the  when-issued  securities  themselves  (which  may  have a value
greater or less than the Series'  payment  obligations).  Sale of  securities to
meet such obligations carries with it a greater potential for the realization of
capital gain or loss.

      Except as described  above and under  Investment  Limitations  below,  the
foregoing  investment  policies are not fundamental and the Trustees of the Fund
may change  such  policies  without  the vote of a majority  of the  outstanding
voting securities of the Fund or any Series (as defined on page 4).

PORTFOLIO  TURNOVER.  Each Series'  portfolio  turnover  rate is  calculated  by
dividing the lesser of purchases or sales of portfolio  securities of the Series
for the fiscal year by the monthly average value of the portfolio  securities of
the Series owned during the fiscal year.  The portfolio  turnover  rates for the
U.S. Government  Securities Series and the High-Yield Bond Series for the fiscal
years ended 1995 and 1994 were  213.06% and  445.18%,  and 173.39% and  184.75%,
respectively.  Securities  whose  maturities or expiration  dates at the time of
acquisition  were one  year or less are  excluded  from  the  calculation.  High
portfolio  turnover involves  correspondingly  greater  transactions costs and a
possible increase in short-term capital gains or losses.

                             INVESTMENT LIMITATIONS

      Under each Series' fundamental policies, which cannot be changed except by
a vote of a majority of its outstanding voting securities, a Series may not:

- -  Borrow money,  except from banks for temporary or emergency purposes (but not
   for the purchase of portfolio  securities)  in an amount not to exceed 15% of
   the  value of the total  assets of the  Series.  A Series  will not  purchase
   additional portfolio securities if such Series has outstanding  borrowings in
   excess of 5% of the value of its total assets;

- -  Mortgage  or pledge  any of its  assets,  except to the extent  necessary  to
   effect borrowings permitted by the preceding paragraph and provided that this
   limitation  does not prohibit  escrow,  collateral or margin  arrangements in
   connection  with  (a)  the  writing  of  covered  call  options  by the  U.S.
   Government  Securities  Series;  (b) the  purchase of put options by the U.S.
   Government  Securities  Series  or (c) the  sale  of  interest  rate  futures
   contracts  and the purchase or sale of options on such  contracts by the U.S.
   Government Securities Series;

- -  Make "short" sales of securities,  or purchase  securities on "margin" except
   that for  purposes  of this  limitation,  initial and  variation  payments or
   deposits in  connection  with  interest  rate futures  contracts  and related
   options by the U.S. Government Securities Series will not be deemed to be the
   purchase  of  securities  on margin;  write or purchase  put or call  options
   except that the U.S.  Government  Securities  Series may write  covered  call
   options and the U.S.  Government  Securities  Series may purchase put options
   and may purchase and sell options on interest  rate futures and may engage in
   closing  transactions with respect to such options. The Series has no present
   intention  of  investing  in these  types of  securities,  and will not do so
   without the prior approval of the Fund's Board of Trustees;

- -  Purchase  securities of any issuer if immediately  thereafter more than 5% of
   total assets at market would be invested in the securities of any one issuer,
   other than the U.S. Government,  its agencies or instrumentalities;  buy more
   than  10% of the  voting  securities  of any  one  issuer,  other  than  U.S.
   Government agencies or instrumentalities;  or invest to control or manage any
   company;

- -  Invest more than 25% of the market value of its total assets in securities of
   issuers  in  any  one   industry;   for  the  purpose  of  this   limitation,
   mortgage-related securities do not constitute an industry;

                                      -3-

- -  Invest  in  securities  issued  by  other  investment  companies,  except  in
   connection with a merger, consolidation, acquisition or reorganization;

- -  Purchase or hold any real estate including limited partnership  interests  in
   real property;

- -  Purchase or sell commodities and commodity  futures contracts except that the
   U.S.  Government  Securities  Series may sell interest rate futures contracts
   and may write call  options and may purchase put options with respect to such
   contracts  and may engage in closing  transactions  with  respect to all such
   transactions. The Series has no present intention of investing in these types
   of  securities,  and will not do so without the prior  approval of the Fund's
   Board of Trustees;

- -  Invest more than 5% of the value of its total  assets,  at market  value,  in
   securities of any company which, with its predecessors, has 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;

- -  Purchase or hold the securities of any issuer, if to its knowledge,  Trustees
   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;

- -  Engage in  transactions  with its  Trustees and  officers,  or firms they are
   associated  with,  in  connection  with the  purchase or sale of  securities,
   except as broker;

- -  Underwrite the securities of other  issuers,  except that in connection  with
   the  disposition of a security a Series may be deemed to be an underwriter as
   defined in the Securities Act of 1933; or

- -  Make loans, except loans of securities of the Series and except to the extent
   the purchase of notes, bonds or other evidences of indebtedness, or the entry
   into repurchase agreements may be considered loans.

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

(1) Based on  remuneration  received  by the  Trustees  of the Fund for the year
ended December 31, 1995.

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

* Retired May 18, 1995.

(d)  Deferred.   As  of  December  31,  1995,  the  total  amounts  of  deferred
compensation  (including interest) payable by the Fund to Messrs.  Merow, Pitney
and Whitson were $29,945, $23,316 and $7,516, respectively. Mr. Pitney no longer
defers current compensation.

      The Fund has a compensation  arrangement  under which outside Trustees may
elect to defer receiving their fees. Under this  arrangement,  interest would be
accrued on the deferred  balances.  The actual cost of such interest is included
in the  Trustee's  fees and expenses,  and the  accumulated  balance  thereof is
included in "Liabilities" in the Fund's financial statements.

   
      Trustees  and  officers  of the  Fund  are also  directors,  trustees  and
officers of some or all of the other investment companies in the Seligman Group.
Trustees and officers of the Fund as a group owned less than 1% of both the U.S.
Government  Securities  Series' and the High-Yield  Bond Series' Class A capital
stock as of December 16, 1996.  As of that date,  no Trustees or officers  owned
shares of either Series' Class B or Class D capital stock.

      As of December 16, 1996,  7,769,918  Class A shares of the High-Yield Bond
Series,  which  equaled  14.42% of the  High-Yield  Bond Series' Class A capital
stock then  outstanding  and 13,169,787  Class D shares of the  High-Yield  Bond
Series,  which  equaled  37.59% of the  High-Yield  Bond Series' Class D capital
stock then  outstanding,  were owned of record by MLPF&S For the Sole Benefit of
Its Customers, 4800 Deer Lake Drive East, 3rd Floor, Jacksonville, FL 32246.

                             MANAGEMENT AND EXPENSES

      Under each Series' Management  Agreement,  dated December 29, 1988 for the
U.S.  Government  Securities Series and December 29, 1988, as amended January 1,
1996, for the High-Yield Bond Series, subject to the control of the Trustees, J.
& W. Seligman & Co.  Incorporated (the "Manager")  manages the investment of the
assets  of each  Series,  including  making  purchases  and  sales of  portfolio
securities consistent with each Series' investment objectives and policies,  and
administers the business and other affairs of each Series.  The Manager provides
the Fund with such office space, administrative and other services and executive
and other personnel as are necessary for Fund  operations.  The Manager pays all
of the  compensation of Trustees of the Fund who are employees or consultants of
the  Manager and the  officers  and  employees  of the Fund.  The  Manager  also
provides  senior  management  for Seligman  Data Corp.,  the Fund's  shareholder
service agent.

      The Manager is entitled to receive a  management  fee from each Series for
its services to such Series,  calculated daily and payable monthly. For the U.S.
Government  Securities Series, the fee is equal to .50% of the average daily net
assets  of the  Series  on an annual  basis.  Effective  January  1,  1996,  the
management  fee for the  High-Yield  Bond Series is equal to .65% of the Series'
average  daily net  assets on the first $1 billion of net assets and .55% of the
Series'  average daily net assets in excess of $1 billion.  The management  fees
paid by each Series for each of 1995,  1994 and 1993 equaled .50% of the average
daily net assets of each Series;  or for the U.S.  Government  Securities Series
and the High-Yield Bond Series,  $301,343,  $338,362 and $296,325; and $723,340,
$329,652 and $251,812, respectively.

      The Fund pays all its  expenses  other than those  assumed by the  Manager
including  brokerage  commissions,  administration,   shareholder  services  and
distribution  fees,  if any,  fees and  expenses of  independent  attorneys  and
auditors,  taxes and governmental fees including fees and expenses of qualifying
the Fund and its shares under federal and state  securities  laws, cost of stock
certificates  and expenses of repurchase  or  redemption of shares,  expenses of
printing and distributing reports,  notices and proxy materials and prospectuses
to existing  shareholders,  expenses of  printing  and filing  reports and other
documents filed with governmental agencies,  expenses of shareholders' meetings,
expenses  of  corporate  data  processing  and  related  services,   shareholder
recordkeeping  and  shareholder  account  services,  fees and  disbursements  of
transfer   agents  and   custodians,   expenses  of  disbursing   dividends  and
distributions,  fees payable under the Administration,  Shareholder Services and
Distribution Plan described below, fees and expenses of Trustees of the Fund not
employed  by (or  serving  as a  Trustee  of)  the  Manager  or its  affiliates,
insurance premiums and extraordinary  expenses such as litigation expenses.  The
Fund's  expenses are  allocated  among the Series in a manner  determined by the
Trustees to be fair and equitable.

      The Manager has undertaken to one state securities administrator,  so long
as required, to reimburse each Series for each year in the amount by which total
expenses,  including the management fee but excluding interest, taxes, brokerage
commissions,  distribution fees and extraordinary expenses, exceed 2 1/2% of the
first  $30,000,000 of average net assets,  2% of the next $70,000,000 of average
net assets,  and 1 1/2%  thereafter.  Such  reimbursement,  if any, will be paid
monthly.

      Each Series'  Management  Agreement was initially approved by the Board of
Trustees on September 30, 1988 and by the shareholders at a special meeting held
on  December  16,  1988.  The  amendments  to the  Management  Agreement  of the
High-Yield  Bond Series,  to increase the fee rate payable to the Manager by the
Series,  were approved by the Board of Trustees on September 21, 1995 and by the
shareholders  at a special  meeting held on December 12,  1995.  The  Management
Agreements will continue until December 31 of each year (1) if such  continuance
is approved  in the manner  required by the 1940 Act (by a vote of a majority of
the Trustees or of the  outstanding  voting  securities  of each Series and by a
vote  of a  majority  of the  Trustees  who are not  parties  to the  Management
Agreement or interested  persons of any such party) and (2) if the Manager shall
not have  notified  a Series at least 60 days prior to  December  31 of any year
that it does not desire  such  continuance.  Each  Management  Agreement  may be
terminated  by the  appropriate  Series,  without  penalty,  on 60 days' written
notice  to the  Manager  and will  terminate  automatically  in the event of its
assignment.  Each Series has agreed to change its name upon  termination  of its
Management  Agreement if continued use of the name would cause  confusion in the
context of the Manager's business.

      The Manager is a successor firm to an investment  banking business founded
in 1864  which has  thereafter  provided  investment  services  to  individuals,
families, institutions and corporations. On December 29, 1988, a majority of the
outstanding  voting  securities of the Manager was  purchased by Mr.  William C.
Morris and a  simultaneous  recapitalization  of the Manager  occurred.  See the
Appendix for further history of the Manager.

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

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

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

           ADMINISTRATION, SHAREHOLDER SERVICES AND DISTRIBUTION PLANS

      Each  Series  of the  Fund  has  adopted  an  Administration,  Shareholder
Services and  Distribution  Plan for each Class (the "Plan") under Section 12(b)
of the 1940 Act and Rule 12b-1 thereunder.

      The Plan was  originally  approved with respect to each Series on April 8,
1986 by the Board of Trustees of the Fund,  including a majority of the Trustees
who are not  "interested  persons"  (as defined in the 1940 Act) of the Fund and
who had no direct or indirect financial interest in the operation of the Plan or
in any  agreement  related  to the Plan (the  "Qualified  Trustees")  and by the
shareholders  of each Series at a meeting of shareholders on April 10, 1986. The
Plan was  approved  in respect of the Class D shares of both  Series on July 15,
1993 by the Board of Trustees of the Fund, including a majority of the Qualified
Trustees,  and became  effective in respect of the Class D shares of both Series
on September 21, 1993. The Plan was approved in respect of the Class B shares of
the  High-Yield  Bond  Series on March 21,  1996 by the Board of Trustees of the
Fund,  including a majority of the Qualified  Trustees,  and became effective in
respect of the Class B shares of the  High-Yield  Bond Series on April 22, 1996.
The Plan was  approved  in respect of the Class B shares of the U.S.  Government
Securities  Series on  September  19, 1996 by the Board of Trustees of the Fund,
including a majority of the Qualified Trustees,  and became effective in respect
of the Class B shares of the U.S.  Government  Securities  Series on  January 1,
1997.  The Plans 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 Trustees
and the Qualified  Trustees of the Fund,  cast in person at a meeting called for
the purpose of voting on such approval.  The Plan may not be amended to increase
materially  the  amounts  payable to Service  Organizations  (as defined in each
Series'  Prospectus)  with respect to a class without the approval of a majority
of the  outstanding  voting  securities of such class.  If the amount payable in
respect  of  Class  A  shares  under  the  Plans  is  proposed  to be  increased
materially, the Fund will either (i) permit holders of Class B shares to vote as
a separate  class on the  proposed  increase  or (ii)  establish  a new class of
shares  subject to the same payment under the Plans 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 Plans may be made
except by a majority of both the Trustees and Qualified Trustees.

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

                             PORTFOLIO TRANSACTIONS

      No brokerage commissions were paid by the Fund during 1995, 1994 and 1993.
When two or more of the  investment  companies  in the  Seligman  Group or other
investment  advisory  clients  of the  Manager  desire  to buy or sell  the same
security at the same time, the securities purchased or sold are allocated by the
Manager 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.

                     PURCHASE AND REDEMPTION OF FUND SHARES

      Each  Series  offers  three  classes  of  shares.  Class A  shares  may be
purchased  at a price  equal to the next  determined  net asset value per share,
plus an initial sales load.  Class A shares purchased at net asset value without
an initial  sales load due to the size of the  purchase are subject to a CDSL if
such shares are redeemed within eighteen months of purchase.  Class B shares may
be purchased at a price equal to the next  determined net asset value without an
initial sales load, but a CDSL may be charged on  redemptions  within 6 years of
purchase.  Class  D  shares  may be  purchased  at a  price  equal  to the  next
determined  net asset value  without an initial  sales  load,  but a CDSL may be
charged  on  redemptions   within  one  year  of  purchase.   See   "Alternative
Distribution  System,"  "Purchase  Of  Shares,"  and  "Redemption  Of Shares" as
applicable, in each Series' Prospectus.

SPECIMEN PRICE MAKE-UP

      Under  the  current  distribution  arrangements  between  the Fund and the
Distributor,  Class A shares are sold at a maximum sales load of 4.75% and Class
B and Class D shares are sold at net asset  value.* Using the net asset value at
June 30, 1996 for each class of the Series,  the maximum  offering price of each
Series' shares is as follows:

CLASS A SHARES - REDUCED INITIAL SALES LOADS

REDUCTIONS  AVAILABLE.  Shares of any Seligman  Mutual Fund sold with an initial
sales  load  in a  continuous  offering  will  be  eligible  for  the  following
reductions:

     VOLUME DISCOUNTS are provided if the total amount being invested in Class A
shares of a Series or in any  combination of shares of the other mutual funds in
the Seligman  Group which are sold with an initial  sales load,  reaches  levels
indicated in the sales load schedule set forth in each Series' Prospectus.

     THE RIGHT OF  ACCUMULATION  allows an investor to combine the amount  being
invested in Class A shares of the other mutual funds in the Seligman  Group sold
with an  initial  sales  load with the total net asset  value of shares of those
Seligman  Mutual Funds  already  owned that were sold with an initial sales load
and the total net asset value of shares of Seligman Cash  Management  Fund which
were  acquired  through  an  exchange  of shares of another  mutual  fund in the
Seligman  Group on which there was an initial sales load at the time of purchase
to determine reduced sales loads in accordance with the schedule in each Series'
Prospectus.  The value of the  shares  owned,  including  the value of shares of
Seligman  Cash  Management  Fund  acquired  in an  exchange of shares of another
mutual fund in the Seligman Group on which there is an initial sales load at the
time of purchase,  will be taken into account in orders placed through a dealer,
however,  only if Seligman Financial  Services,  Inc. ("SFSI") 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 of a
Series'  shares  over a  13-month  period  at  reduced  initial  sales  loads in
accordance  with the  schedule in each  Series'  Prospectus,  based on the total
amount of Class A shares of the  Series  that the  letter  states  the  investor
intends to purchase plus the total net asset value of shares that were sold with
an initial  sales load of the other mutual funds in the Seligman  Group  already
owned and the total net asset value of shares of Seligman Cash  Management  Fund
which were acquired  through an exchange of shares of another mutual fund in the
Seligman Group on which there was an initial sales load at the time of purchase.
Reduced  sales loads also may apply to purchases  made within a 13-month  period
starting up to 90 days before the date of execution  of a letter of intent.  For
more  information  concerning the terms of the letter of intent,  see "Terms and
Conditions -- Letter of Intent" accompanying the Account Application.

     Class A shares  purchased  without an initial sales load in accordance with
the sales load  schedule  in each  Series'  Prospectus,  or pursuant to a Volume
Discount,  Right of Accumulation or Letter of Intent are subject to a CDSL of 1%
on redemptions of such shares within eighteen months of purchase.

PERSONS  ENTITLED  TO  REDUCTIONS.  Reductions  in initial  sales loads apply to
purchases  of Class A shares  of a Series  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,  tax-exempt  organizations  under Section 501
(c)(3) or (13), and  non-qualified  employee  benefit plans that satisfy uniform
criteria are considered "single persons" for this purpose.  The uniform criteria
are as follows:

1. Employees  must authorize the employer,  if requested by the Fund, to receive
in bulk  and to  distribute  to each  participant  on a  timely  basis  the Fund
prospectuses, 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  loads in each  Series'
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 (i)  $500,000  invested  in the  Seligman  Group of
Mutual Funds or (ii) 50 eligible  employees to whom such plan is made available.
Such sales must be made in connection  with a payroll  deduction  system of plan

                                      -12-


<PAGE>


funding  or  other  systems  acceptable  to  Seligman  Data  Corp.,  the  Fund's
shareholder  service  agent.  Such sales are believed to require  limited  sales
effort and sales  related  expenses and  therefore  are made at net asset value.
Contributions  or account  information  for plan  participation  also  should be
transmitted  to Seligman  Data Corp.  by methods  which it  accepts.  Additional
information about "eligible employee benefit plans" is available from investment
dealers or SFSI.  The term  "eligible  employee  benefit plan" means any plan or
arrangement,  whether or not tax  qualified,  which provides for the purchase of
Fund shares.

PAYMENT IN SECURITIES.  In addition to cash,  the Fund may accept  securities in
payment for shares of a Series sold at the applicable public offering price (net
asset value plus any applicable sales load) although the Fund does not presently
intend to accept  securities in payment for Series shares.  Generally,  the Fund
will only  consider  accepting  securities  (l) to  increase  its  holdings in a
portfolio  security  of a  Series,  or (2) if the  Manager  determines  that the
offered  securities  are a suitable  investment for a Series 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 shares of a Series with  securities,  may require partial
payment  in cash for  applicable  sales  loads,  and may  discontinue  accepting
securities as payment for shares of the Series at any time without  notice.  The
Fund will not accept  restricted  securities in payment for Series  shares.  The
Fund will value accepted securities in the manner provided for valuing portfolio
securities of the Fund. Any securities  accepted by the Fund in payment for Fund
shares  will have an active and  substantial  market  and have a value  which is
readily  ascertainable  (See  "Valuation").  In accordance with Texas securities
regulations,  should the Fund accept  securities  in payment  for  shares,  such
transactions would be limited to a bona fide  reorganization,  statutory merger,
or to other  acquisitions  of portfolio  securities  (except for municipal  debt
securities  issued  by  state  political   subdivisions  or  their  agencies  or
instrumentalities)  which meet the  investment  objectives  and  policies of the
investment  company;  are acquired for investment and not for resale; are liquid
securities which are not restricted as to transfer either by law or liquidity of
market;  and have a value which is readily  ascertainable  (and not  established
only by evaluation  procedures)  as evidenced by a listing on the American Stock
Exchange, the New York Stock Exchange ("NYSE") or NASDAQ.

FURTHER TYPES OF REDUCTIONS. Class A shares of each Series may be issued without
a sales load in connection with the acquisition of cash and securities  owned by
other  investment   companies  and  personal  holding   companies  to  financial
institution trust  departments,  to registered  investment  advisers  exercising
discretionary  investment authority with respect to the purchase of Fund shares,
or  pursuant  to   sponsored   arrangements   with   organizations   which  make
recommendations  to, or permit group solicitation of, its employees,  members or
participants  in connection with the purchase of shares of the Fund, to separate
accounts  established  and  maintained by an insurance  company which are exempt
from  registration  under  Section  3(c)(11)  of the  1940  Act,  to  registered
representatives  and  employees  (and their  spouses and minor  children) of any
dealer that has a sales  agreement  with SFSI, to  shareholders  of mutual funds
with investment objectives and policies similar to a Series' who purchase shares
with redemption  proceeds of such funds and to certain unit investment trusts as
described in each Series' Prospectus.

     Class A shares of each  Series  also may be issued  without a sales load to
present and retired directors,  trustees,  officers, employees (and their family
members,  as  defined  in each  Series'  Prospectus)  of the  Funds,  the  other
investment  companies in the  Seligman  Group,  the Manager and other  companies
affiliated  with the  Manager.  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 the Manger or
any affiliate.  These 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.

MORE ABOUT  REDEMPTIONS.  The  procedures  for  redemption  of Fund shares under
ordinary  circumstances  are set forth in each  Series'  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.  Payment  may be made in  securities,  subject to the review of some
state securities  commissions.  If payment is made in securities,  a shareholder
may incur brokerage expenses in converting these securities to cash.

                              DISTRIBUTION SERVICES

SFSI, an affiliate of the Manager,  acts as a general  distributor of the shares
of the Fund and of the other mutual funds in the  Seligman  Group.  The Fund and
SFSI are parties to a Distributing  Agreement  dated January 1, 1993. As general
distributor of the Fund's shares of beneficial interest, SFSI allows commissions
to dealers as indicated in each Series' Prospectus. SFSI receives the balance of
sales loads and any CDSL, if applicable,  paid by investors. The following table
sets  forth the  concessions  received  by SFSI,  dealer  commissions,  and CDSL
retained for each Series for 1995, 1994 and 1993.

                                    VALUATION

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

    Portfolio  securities,  including open short positions and options  written,
are  valued at the last sale  price on the  securities  exchange  or  securities
market on which such securities  primarily are traded.  Securities not listed on
an  exchange  or  securities  market,  or  securities  in  which  there  were no
transactions,  are valued at the average of the most recent bid and asked price,
except in the case of open short  positions  where the asked price is available.
Any  securities for which recent market  quotations  are not readily  available,
including  restricted  securities,  are  valued at fair value as  determined  in
accordance with procedures approved by the Fund's Trustees. This value generally
is  determined as the amount which a Series could  reasonably  expect to receive
from an orderly  disposition  of these  securities  over a reasonable  period of
time. Short-term obligations with less than sixty days remaining to maturity are

                                      -14-

generally valued at amortized cost. Short-term  obligations with more than sixty
days  remaining  to maturity  will be valued at current  market  value until the
sixtieth  day prior to maturity,  and will then be valued on an  amortized  cost
basis  based on the value on such date  unless  the Board  determines  that this
amortized cost value does not represent fair market value.  Premiums received on
the sale of call options  will be included in the net asset  value,  and current
market value of the options sold by a Series will be  subtracted  from net asset
value.

                                   PERFORMANCE

    The  annualized  yield for the 30-day period ended December 31, 1995 for the
Class A shares of the U.S. Government  Securities Series and the High-Yield Bond
Series was 5.09% and 8.99%,  respectively.  The annualized yield was computed by
dividing each Series' net  investment  income per share earned during the 30-day
period by the maximum  offering price per share (i.e.,  the net asset value plus
the maximum  sales load of 4.75% of the net amount  invested)  on  December  31,
1995,  which  was the last day of this  period.  The  average  number of Class A
shares of the U.S.  Government  Securities Series and the High-Yield Bond Series
was 7,762,497 and 25,045,807,  respectively,  which was the average daily number
of shares  outstanding  during the 30-day  period that were  eligible to receive
dividends.  The  annualized  yield for the 30-day period ended December 31, 1995
for the  Class  D  shares  of the  U.S.  Government  Securities  Series  and the
High-Yield Bond Series was 4.50% and 8.66%,  respectively.  The annualized yield
was  computed by dividing  each Series' net  investment  income per share earned
during the 30-day period by the maximum  offering price per share (i.e., the net
asset value) on December 31,  1995,  which was the last day of this period.  The
average number of Class D shares of the U.S.  Government  Securities  Series and
the High-Yield Bond Series was 1,122,691 and 12,328,074, respectively, which was
the average  daily number of shares  outstanding  during the 30-day  period that
were eligible to receive dividends. Income was computed by totaling the interest
earned on all debt  obligations  during the 30-day period and  subtracting  from
that amount the total of all recurring  expenses incurred during the period. The
30-day yield was then annualized on a bond-equivalent basis assuming semi-annual
reinvestment  and  compounding  of net investment  income,  as described in each
Series' Prospectus.

    The  average  annual  total  returns  for the  Class A  shares  of the  U.S.
Government  Securities  Series and the High-Yield  Bond Series for the one-year,
five-year and ten-year periods ended on December 31, 1995 were 12.58%, 7.01% and
7.09%; and 14.92%, 16.73% and 10.73%, respectively.  These returns were computed
by  subtracting  the maximum  sales load of 4.75% of public  offering  price and
assuming  that all of the  dividends  and  distributions  by the Series 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 redemption  (i.e., the
average annual compound rate of return). The total return for the Class D shares
of the U.S. Government  Securities Series and the High-Yield Bond Series for the
one-year  period and since inception  through  December 31, 1995 were 16.10% and
4.47%; and 18.67% and 10.19%, respectively. These amounts were computed assuming
that all of the dividends and distributions paid by each Series' 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%
CDSL, if applicable.  Performance information is not provided for Class B shares
because no Class B shares were outstanding during the quoted periods.

    Table A below  illustrates  the total return (income and capital) on Class A
shares of each Series of the Fund with dividends invested and gain distributions
taken in shares. It shows that a $1,000 investment in Class A shares of the U.S.
Government Securities Series,  assuming payment of the 4.75% sales load, made on
January 1, 1986 had a value of $1,983 on  December  31,  1995,  resulting  in an
aggregate total return of 98.33%;  and a $1,000  investment in Class A shares of
the High-Yield  Bond Series,  assuming  payment of the 4.75% sales load, made on
September  21,  1993  (commencement  of  operations)  had a value of  $2,772  on
December 31, 1995,  resulting in an aggregate  total return of 177.17%.  Table B
illustrates  the total return (income and capital) on Class D shares of the U.S.
Government  Securities  Series and the  High-Yield  Bond Series  with  dividends
invested and gain distributions taken in shares.

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

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

   Each of the  Series  may also  include  its  aggregate  total  return  over a
specified  period in  advertisements  or in information  furnished to present or
prospective shareholders.

                               GENERAL INFORMATION

INFORMATION ABOUT BUSINESS TRUSTS. As indicated in each Series' Prospectus,  the
Fund is  organized  as a business  trust under the laws of the  Commonwealth  of
Massachusetts.   Under  the  Declaration  of  Trust,  the  Fund's  Trustees  are
authorized to classify or reclassify and issue any shares of beneficial interest
of the  Fund  into  any  number  of  other  Series  without  further  action  by
shareholders. The 1940 Act requires that where more than one Series exists, each
Series must be preferred over all other Series in respect of assets specifically
allocated to such Series.

   As a general  matter,  the Fund will not hold annual or other meetings of the
shareholders.  This is because the Declaration of Trust provides for shareholder
voting only (a) for the election or removal of one or more Trustees if a meeting
is  called  for that  purpose,  (b) with  respect  to any  contract  as to which
shareholder  approval  is  required  by the 1940 Act,  (c) with  respect  to any
termination  or  reorganization  of the Fund or any  Series to the extent and as
provided in the  Declaration of Trust,  (d) with respect to any amendment of the
Declaration of Trust (other than  amendments  establishing  and  designating new
Series, abolishing Series when there are no units thereof outstanding,  changing
the name of the Fund or the name of any Series,  supplying any omission,  curing
any ambiguity or curing, correcting or supplementing any provision thereof which
is  internally  inconsistent  with  any  other  provision  thereof  or  which is
defective  or  inconsistent  with the 1940 Act or with the  requirements  of the
Internal  Revenue Code of 1986, as amended,  or applicable  regulations  for the
Fund's obtaining the most favorable treatment  thereunder available to regulated
investment  companies),  which amendments  require approval by a majority of the
shares  entitled  to  vote,  (e) to the same  extent  as the  stockholders  of a
Massachusetts  business  corporation  as  to  whether  or  not a  court  action,
proceeding,  or claim should or should not be brought or maintained derivatively
or as a class  action on behalf  of the Fund or the  shareholders,  and (f) with
respect to such  additional  matters  relating to the Fund as may be required by
the  1940  Act,  the  Declaration  of  Trust,  the  By-laws  of  the  Fund,  any
registration  of the Fund  with the  Securities  and  Exchange  Commission  (the
"Commission")  or any  state,  or as the  Trustees  may  consider  necessary  or
desirable.  Each Trustee serves until the next meeting of shareholders,  if any,
called for the purpose of considering the election or reelection of such Trustee
or of a successor to such Trustee,  and until the election and  qualification of
his  successor,  if any,  elected at such meeting,  or until such Trustee sooner
dies,  resigns,  retires or is removed by the  shareholders or two-thirds of the
Trustees.

   The shareholders of the Fund have the right,  upon the declaration in writing
or vote of more than two-thirds of the Fund's  outstanding  shares,  to remove a
Trustee. The Trustees will call a meeting of shareholders to vote on the removal
of a Trustee  upon the written  request of the record  holders of ten percent of
its shares.  In addition,  whenever ten or more  shareholders of record who have
been such for at least six months  preceding  the date of  application,  and who
hold in the aggregate either shares having a net asset value of at least $25,000
or at least 1 per centum of the  outstanding  shares,  whichever is less,  shall
apply to the  Trustees in writing,  stating that they wish to  communicate  with
other  shareholders  with a view to  obtaining  signatures  to a  request  for a
meeting for the purpose of voting upon the question of removal of any Trustee or
Trustees and accompanied by a form of communication  and request which they wish
to transmit,  the Trustees shall within five business days after receipt of such
application  either: (1) afford to such applicants access to a list of the names
and addresses of all  shareholders  as recorded on the books of the Fund; or (2)
inform such applicants as to the  approximate  number of shareholders of record,
and the approximate cost of mailing to them the proposed  communication and form
of requests.  If the Trustees elect to follow the latter  course,  the Trustees,
upon the  written  request of such  applicants,  accompanied  by a tender of the
material to be mailed and of the  reasonable  expenses of mailing,  shall,  with
reasonable promptness, mail such material to all shareholders of record at their
addresses as recorded on the books,  unless within five business days after such

                                      -17-


<PAGE>


tender the Trustees shall mail to such  applicants and file with the Commission,
together with a copy of the material to be mailed, a written statement signed by
at least a majority of the Trustees to the effect that in their  opinion  either
such  material  contains  untrue  statements  of fact or omits  to  state  facts
necessary to make the statements  contained therein not misleading,  or would be
in violation of applicable law, and specifying the basis of such opinion.  After
opportunity for hearing upon the objections  specified in the written  statement
so filed,  the  Commission  may,  and if  demanded  by the  Trustees  or by such
applicants  shall,  enter  an  order  either  sustaining  one or  more  of  such
objections or refusing to sustain any of them. If the Commission  shall enter an
order refusing to sustain any of such  objections,  or if, after the entry of an
order  sustaining one or more of such  objections,  the  Commission  shall find,
after notice and opportunity for hearing,  that all objections so sustained have
been met, and shall enter an order so declaring,  the Trustees shall mail copies
of such material to all shareholders with reasonable  promptness after the entry
of such order and the renewal of such tender.

   Rule  18f-2  under the 1940 Act  provides  that any  matter  required  by the
provisions  of the  1940  Act or  applicable  state  law,  or  otherwise,  to be
submitted 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
Series affected by such matter.  Rule 18f-2 further provides that a Series shall
be deemed to be affected by a matter  unless it is clear that the  interests  of
such Series in the matter are  substantially  identical  or that the matter does
not significantly affect any interest of such Series.  However, the Rule exempts
the selection of independent  auditors,  the approval of principal  distributing
contracts and the election of trustees from the separate voting  requirements of
the Rule.

   The  shareholders  of a  Massachusetts  business  trust could,  under certain
circumstances,  be held  personally  liable  as  partners  for its  obligations.
However,  the Declaration of Trust contains an express disclaimer of shareholder
liability for acts or  obligations of the Trust.  The  Declaration of Trust also
provides  for  indemnification  and  reimbursement  of expenses out of a Series'
assets  for any  shareholder  held  personally  liable for  obligations  of such
Series.

CUSTODIAN. Investors Fiduciary Trust Company, 127 West 10th Street, Kansas City,
Missouri 64105,  serves as custodian for the Fund. It also maintains,  under the
general  supervision of the Manager,  the accounting  records and determines the
net asset values for the Fund.

AUDITORS. Deloitte & Touche LLP, independent auditors, have been selected as
auditors of the Fund. Their address is Two World Financial Center, New York, New
York 10281.

         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.

                                   ARTICLE II

                                    TRUSTEES


         SECTION 2.1.  NUMBER OF TRUSTEES.  The number of Trustees shall be such
number as shall be fixed from time to time by a written  instrument  signed by a
majority of the Trustees then in office,  provided,  however, that the number of
Trustees shall in no event be less than two.

         SECTION  2.2.  ELECTION AND TERM.  The  Trustees  shall be elected by a
Majority  Shareholder  Vote at the first meeting of  Shareholders  following the
initial  offering of Shares of the Trust.  The Trustees  shall have the power to
set and alter the terms of the office of the Trustees,  and they may at any time
lengthen or lessen  their own terms or make their terms of  unlimited  duration,
subject to the resignation and removal provisions of Section 2.3 hereof. Subject
to Section 16 (a) of the 1940 Act, the  Trustees may elect their own  successors
and may, pursuant to Section 2.4 hereof, appoint Trustees to fill vacancies. The
Trustees  shall adopt  By-Laws not  inconsistent  with this  Declaration  or any
provision  of law to provide for  election of Trustees by  Shareholders  at such
time or times as the Trustees shall determine to be necessary or advisable.

         SECTION 2.3.  RESIGNATION AND REMOVAL. Any Trustee may resign his trust
(without  need for prior or subsequent  accounting)  by an instrument in writing
signed by him and delivered to the other Trustees and such resignation  shall be
effective upon such  delivery,  or at a later date according to the terms of the
instrument. Any of the Trustees may be removed (provided the aggregate number of
Trustees  after  such  removal  shall not be less than the  number  required  by
Section 2.1 hereof) with cause,  by the action of  two-thirds  of the  remaining
Trustees. Upon the resignation or removal of a Trustee, or his otherwise ceasing
to be a Trustee,  he shall  execute and deliver such  documents as the remaining
Trustees shall require for the purpose of conveying to the Trust (or appropriate
series thereof) or the remaining  Trustees any Trust Property or property of any
series  thereof held in the name of the resigning or removed  Trustee.  Upon the
incapacity or death of any Trustee,  his legal  representative shall execute and
deliver on his behalf such documents as the remaining  Trustees shall require as
provided in the preceding sentence.

         SECTION 2.4. VACANCIES. The term of office of a Trustee shall terminate
and a vacancy  shall  occur in the  event of the  death,  resignation,  removal,
bankruptcy,  adjudicated  incompetence or other incapacity to perform the duties
of the  office  of a  Trustee.  No such  vacancy  shall  operate  to  annul  the
Declaration or to revoke any existing  agency  created  pursuant to the terms of
the  Declaration.  In the  case of an  existing  vacancy,  including  a  vacancy
existing  by reason of an  increase  in the number of  Trustees,  subject to the
provisions of Section 16 (a) of the 1940 Act, the  remaining  Trustees or, prior
to the public  offering of Shares of the Trust,  if only one Trustee  shall them
remain  in  office,  the  remaining  Trustee,  shall  fill such  vacancy  by the
appointment  of such  other  person as they or he,  in their or his  discretion,
shall  see  fit,  made by a  written  instrument  signed  by a  majority  of the
remaining  Trustees or by the  remaining  Trustee,  as the case may be. Any such
appointment shall not become effective,  however,  until the person named in the
written   instrument  of  appointment   shall  have  accepted  in  writing  such
appointment  and agreed in writing to be bound by the terms of the  Declaration.
An appointment of a Trustee may be made in anticipation of a vacancy to occur at
a later date by reason of  retirement,  resignation or increase in the number of
Trustees,  provided that such  appointment  shall not become  effective prior to
such retirement,  resignation or increase in the number of Trustees.  Whenever a
vacancy in the number of Trustees  shall occur,  until such vacancy is filled as
provided in this Section 2.4, the Trustee in office, regardless of their number,
shall have all the powers  granted to the Trustees and shall  discharge  all the
duties  imposed  upon the  Trustees  by the  Declaration.  A written  instrument
certifying  the  existence of such vacancy  signed by a majority of the Trustees
shall be conclusive evidence of the existence of such vacancy.

         SECTION 2.5. DELEGATION OF POWER TO OTHER TRUSTEES. Any Trustee may, by
power of attorney,  delegate his power for a period not exceeding six (6) months
at any one time to any other Trustee or Trustees; provided that in no case shall
less  than two (2)  Trustees  personally  exercise  the  powers  granted  to the
Trustees under the Declaration except as herein otherwise expressly provided.

                                   ARTICLE III

                                POWER OF TRUSTEES



         SECTION 3.1.  GENERAL.  The Trustees  shall have exclusive and absolute
control  over the Trust  Property,  including  the property of any series of the
Trust,  and over the business of the Trust to the same extent as if the Trustees
were the sole owners of such property and business in their own right,  but with
such powers of delegation as may be permitted by the  Declaration.  The Trustees
shall  have  power  to  conduct  the  business  of the  Trust  and  carry on its
operations  in any and all of its branches and maintain  offices both within and
without the Commonwealth of  Massachusetts,  in any and all states of the United
States of America, in the District of Columbia,  in foreign countries and in any
and  all  commonwealths,   territories,   dependencies,  colonies,  possessions,
agencies  or  instrumentalities  of the United  States of America and of foreign
governments, and to do all such other things and execute all such instruments as
they deem  necessary,  proper or desirable in order to promote the  interests of
the Trust  although  such  things are not  herein  specifically  mentioned.  Any
determination  as to what is in the  interests of the Trust made by the Trustees
in  good  faith  shall  be  conclusive.  In  construing  the  provisions  of the
Declaration,  the  presumption  shall  be in  favor  of a grant  of power to the
Trustees.

         The  enumeration of any specific power herein shall not be construed as
limiting  the  aforesaid  power.  Such powers of the  Trustees  may be exercised
without order of or resort to any court.

         SECTION 3.2.  INVESTMENTS.  The Trustees shall have the power to:

         (a)  conduct,  operate  and  carry  on the  business  of an  investment
         company;

         (b)  subscribe  for,  invest in,  reinvest  in,  purchase or  otherwise
         acquire, hold, pledge, sell, assign,  transfer,  exchange,  distribute,
         lend or  otherwise  deal in or dispose  of  securities,  negotiable  or
         non-negotiable  instruments,  obligations,  evidences of  indebtedness,
         certificates of deposit or indebtedness,  commercial paper,  repurchase
         agreements, reverse repurchase agreements, options and other securities
         and  commodities  and  commodities   futures  contracts  of  any  kind,
         including without limitation,  those issued, guaranteed or sponsored by
         any and all Persons including, without limitation,  states, territories
         and possessions of the United States,  the District of Columbia and any
         of the political subdivisions,  agencies or instrumentalities  thereof,
         and   by  the   United   States   Government   or   its   agencies   or
         instrumentalities,  or international instrumentalities,  or by any bank
         or savings institution, or by any corporation or organization organized
         under the laws of the  United  States  or of any  state,  territory  or
         possession  thereof,  and of  corporations or  organizations  organized
         under foreign laws, or in "when issued" or "delayed delivery" contracts
         for any such  securities,  or retain Trust assets in cash and from time
         to time  change the  investments  of the  assets of the  Trust;  and to
         exercise  any and all rights,  powers and  privileges  of  ownership of
         interest in respect of any and all such  investments  of every kind and
         description,  including,  without limitation,  the right to consent and
         otherwise act with respect thereto, with power to designate one or more
         persons,  firms,  associations  or corporations to exercise any of said
         rights,  powers and  privileges in respect of any of said  instruments;
         and the  Trustees  shall be deemed to have the  foregoing  powers  with
         respect  to any  additional  securities  in which the Trust may  invest
         should the Fundamental Policies be amended.

<PAGE>

The Trustees  shall not be limited to investing in obligations  maturing  before
the possible  termination of the Trust, nor shall the Trustees be limited by any
law limiting the investments which may be made by fiduciaries.

         SECTION  3.3.  LEGAL  TITLE.  Legal  title to all the  Trust  Property,
including the Property, including the property of any series of the Trust, shall
be vested in the Trustees as joint tenants  except that the Trustees  shall have
power to cause legal title to any Trust Property to be held by or in the name of
one or more of the Trustees,  or in the name of the Trust, or in the name of any
other Person as nominee,  on such terms as the Trustees may determine,  provided
that the interest of the Trust therein is  appropriately  protected.  The right,
title and  interest of the  Trustees in the Trust  Property  and the property of
each  series  of the Trust  shall  vest  automatically  in each  Person  who may
hereafter become a Trustee. Upon the resignation,  removal or death of a Trustee
he shall  automatically cease to have any right, title or interest in any of the

                                    ARTICLE V

                           LIMITATIONS OF LIABILITY OF
                        SHAREHOLDERS, TRUSTEES AND OTHERS



         SECTION 5.1. NO PERSONAL LIABILITY OF SHAREHOLDERS,  TRUSTEES,  ETC. No
Shareholder shall be subject to any personal liability  whatsoever to any Person
in connection  with Trust  Property or the acts,  obligations  or affairs of the
Trust. No Trustee,  officer,  employee or agent of the Trust shall be subject to
any personal  liability  whatsoever  to any Person,  other than the Trust or its
Shareholders,  in  connection  with Trust  Property or the affairs of the Trust,
save only that arising from bad faith, wilful  misfeasance,  gross negligence or
reckless  disregard  for his or its duty to such  Person;  and all such  Persons
shall look solely to the Trust Property for satisfaction of claims of any nature
arising  in  connection  with the  affairs  of the  Trust.  If any  Shareholder,
Trustee,  officer,  employee or agent,  as such, of the Trust is made a party to
any suit or  proceeding  to enforce any such  liability,  he or it shall not, on
account thereof,  be held to any personal  liability.  The Trust shall indemnify
and hold each  Shareholder  harmless from and against all claims and liabilities
to which such  Shareholder  may become  subject by reason of his being or having
been a Shareholder, and shall reimburse such Shareholder for all legal and other
expenses  reasonably  incurred  by him in  connection  with  any  such  claim or
liability,  and,  upon request of such  Shareholder,  the Trust shall assume the
defense of any claim made  against  such  Shareholder  by reason of his being or
having been a Shareholder;  provided that any such expenses shall be paid solely
out of the funds and  property of the series of the Trust with  respect to which
such Shareholder's Shares are issued. The rights accruing to a Shareholder under
this Section 5.1 shall not exclude any other right to which such Shareholder may
be lawfully entitled,  nor shall anything herein contained restrict the right of
the Trust to indemnify or reimburse a Shareholder in any  appropriate  situation
even though not specifically provided herein.

         SECTION  5.2.  NON-LIABILITY  OF  TRUSTEES,  ETC. No Trustee,  officer,
employee or agent of the Trust shall be liable to the Trust,  its  Shareholders,
or to any  Shareholder,  Trustee,  officer,  employee,  or agent thereof for any
action or failure to act (including  without limitation the failure to compel in
any way any former or acting  Trustee to redress any breach of trust) except for
his or its own bad faith,  wilful  misfeasance,  gross  negligence  or  reckless
disregard of his or its duties.

         SECTION 5.3.  INDEMNIFICATION.

         (a) The  Trustees  shall  provide for  indemnification  by the Trust of
         every  person  who is, or has been,  a Trustee  or officer of the Trust
         against all liability and against all expenses  reasonably  incurred or
         paid by him in connection with any claim, action, suit or proceeding in
         which he  becomes  involved  as a party or  otherwise  by virtue of his
         being or having been a Trustee or officer and against  amounts  paid or
         incurred by him in the settlement thereof, in such manner not otherwise
         prohibited  or limited by law as the  Trustees may provide from time to
         time in the By-Laws.

<PAGE>

         (b) The words "claim," "action," "suit," or "proceeding" shall apply to
         all claims,  actions, suits or proceedings (civil,  criminal, or other,
         including appeals), actual or threatened; and the words "liability" and
         "expenses" shall include,  without limitation,  attorneys' fees, costs,
         judgments,  amounts  paid in  settlement,  fines,  penalties  and other
         liabilities.

         SECTION  5.4.  NO BOND  REQUIRED  OF  TRUSTEES.  No  Trustee  shall  be
obligated to give any bond or other  security for the  performance of any of his
duties hereunder.

         SECTION  5.5. NO DUTY OF  INVESTIGATION;  NOTICE IN TRUST  INSTRUMENTS,
ETC. No  purchaser,  lender,  transfer  agent or other  Person  dealing with the
Trustees or any  officer,  employee or agent of the Trust shall be bound to make
any inquiry concerning the validity of any transaction  purporting to be made by
the  Trustees  or by said  officer,  employee  or  agent  or be  liable  for the
application of money or property paid,  loaned,  or delivered to or on the order
of the  Trustees  or of  said  officer  employee  or  agent.  Every  obligation,
contract,  instrument,  certificate,  Share,  other  security  of the  Trust  or
undertaking,  and  every  other  act or  thing  whatsoever  executed  or done in
connection with the Trust shall be  conclusively  presumed to have been executed
or done by the executors  thereof only in their  capacity as Trustees  under the
Declaration or in their capacity as officers,  employees or agents of the Trust.
Every  written  obligation,  contract,  instrument,  certificate,  Share,  other
security of the Trust or undertaking made or issued by the Trustees shall recite
that the same is  executed  or made by them not  individually,  but as  Trustees
under the  Declaration,  and that the obligations of any such instrument are not
binding upon any of the Trustees or  Shareholders,  individually,  but bind only
the Trust Estate,  and may contain any further recital which they or he may deem
appropriate,  but the  omission  of such  recital  shall not operate to bind the
Trustees or Shareholders individually.  The Trustees shall at all times maintain
insurance for the protection of the Trust Property, its Shareholders,  Trustees,
officers,  employees  and  agents in such  amount  as the  Trustees  shall  deem
adequate to cover  possible  tort  liability,  and such other  insurance  as the
Trustees in their sole judgment shall deem advisable.

         SECTION  5.6.  RELIANCE ON EXPERTS,  ETC.  Each  Trustee and officer or
employee of the Trust  shall,  in the  performance  of his duties,  be fully and
completely  justified and protected with regard to any act or any failure to act
resulting from reliance in good faith upon the books of account or other records
of the Trust,  upon an opinion of counsel,  or upon reports made to the Trust by
any of its  officers  or  employees  or by the  Adviser,  the  Distributor,  the
Custodian,  the Transfer  Agent,  accountants,  appraisers  or other  experts or
consultants selected with reasonable care by the Trustees, officers or employees
of the  Trust,  regardless  of  whether  such  counsel  or expert  may also be a
Trustee.

                                   ARTICLE VI

                          SHARES OF BENEFICIAL INTEREST


         SECTION 6.1.  BENEFICIAL  INTEREST.  The interest of the  beneficiaries
hereunder shall be divided into  transferable  shares of beneficial  interest of
$.001 par value of two  separate  investment  series,  designated  as " Seligman
High-Yield Bond Series: and "Seligman U.S. Government  Securities  Series".  The
number of shares of beneficial  interest  authorized  hereunder is limited.  The
Trustees may initially issue whole and fractional shares of three classes within
each  series,  designated  " Class A  Shares",  "Class B  Shares"  and  "Class D
Shares",  each of which  shall  represent  an equal  proportionate  share in the
series of the Trust with each other  Share.  The  Trustees may divide or combine
the shares into a greater or lesser number of shares  without  thereby  changing
the proportionate  beneficial  interests in the Trust. Subject to the provisions
of Section  6.9 hereof,  the  Trustees  may also  authorize  the  creation of an
additional  series of shares (the proceeds of which may be invested in separate,
independently  managed  portfolios) and additional  classes of shares within any
series. All Shares issued hereunder including, without limitation, Shares issued
in  connection  with a dividend  in Shares or a split in Shares,  shall be fully
paid and nonassessable.

         SECTION  6.2.  RIGHTS  OF  SHAREHOLDERS.  The  ownership  of the  Trust
Property and the property of each series of the Trust of every  description  and
the right to conduct any business hereinbefore  described are vested exclusively
in the Trustees,  and the Shareholders shall have no interest therein other than
the beneficial  interest conferred by their Shares, and they shall have no right
to call for any  partition  or  division  of any  property,  profits,  rights or
interests  of the Trust nor can they be called  upon to assume any losses of the
Trust or  suffer an  assessment  of any kind by  virtue  of their  ownership  of
Shares.  The Shares  shall be  personal  property  giving only the rights in the
Declaration  specifically  set forth. The Shares shall not entitle the holder to
preference,  preemptive, appraisal, conversion or exchange rights, except as the
Trustees  may  determine  with  respect to any  series or class of Shares.  Upon
liquidation  of the Trust,  holders of the Shares are entitled to share pro rata
in the net assets of the Trust available for  distribution to the holders except
as provided by Section 6.9 (f) with respect to the holders of  different  series
or classes of Shares as provided in Section 6.9.

         SECTION 6.3.  TRUST ONLY. It is the intention of the Trustees to create
only the  relationship of Trustee and beneficiary  between the Trustees and each
Shareholder from time to time. It is not the intention of the Trustees to create
a  general   partnership,   limited   partnership,   joint  stock   association,
corporation,  bailment  or any form of legal  relationship  other  than a trust.
Nothing in the Declaration shall be construed to make the  Shareholders,  either
by  themselves  or with the  Trustees,  partners  or  members  of a joint  stock
association.

<PAGE>

         SECTION 6.4.  ISSUANCE OF SHARES.  The Trustees,  in their  discretion,
may,  from time to time  without  vote of the  Shareholders,  issue  Shares,  in
addition  to the then  issued and  outstanding  Shares  and  Shares  held in the
Treasury,   to  such  party  or  parties   and  for  such  amount  and  type  of
consideration,  including  cash or property,  at such time or times  (including,
without  limitation,  each business day in accordance  with the maintenance of a
constant net asset value per Share),  and on such terms as the Trustees may deem
best, and may in such manner acquire other assets  (including the acquisition of
assets  subject to, and in connection  with the assumption of  liabilities)  and
businesses.  In connection  with any issuance of Shares,  the Trustees may issue
fractional  Shares.  The  Trustees  may from time to time  divide or combine the
Shares  into  a  greater  or  lesser  number   without   thereby   changing  the
proportionate  beneficial  interests in the Trust.  Reductions  in the number of
outstanding  Shares may be made  pursuant  to the  provisions  of Section 8.3 in
order to maintain a constant net asset value per Share of any series  attempting
to maintain such a constant net asset value.  Contributions  to the Trust may be
accepted for, and the Shares shall be redeemed as, whole Shares and/or fractions
of a Share as described in the Prospectus.

         SECTION  6.5.  REGISTER  OF  SHARES.  A  register  shall be kept at the
principal  office of the Trust or at an office of the Transfer Agent which shall
contain the names and  addresses  of the  Shareholders  and the number of Shares
held by them respectively and a record of all transfers  thereof.  Such register
may be in written form or any other form capable of being converted into written
form within a reasonable  time for visual  inspection.  Such  register  shall be
conclusive  as to who are the holders of the Shares and who shall be entitled to
receive  dividends or distributions or otherwise to exercise or enjoy the rights
of  Shareholders.  No  Shareholder  shall be entitled to receive  payment of any
dividend or  distribution,  nor to have notice  given to him as herein or in the
By-Laws  provided,  until he has given his address to the Transfer Agent or such
other officer or agent of the Trustees as shall keep the said register for entry
thereon. It is not contemplated that certificates will be issued for the Shares;
however, the Trustees, in their discretion,  may authorize the issuance of Share
certificates and promulgate appropriate rules and regulations as to their use.

         SECTION 6.6.  TRANSFER OF SHARES.  Shares shall be  transferable on the
records of the Trust only by the record holder thereof or by his agent thereunto
duly authorized in writing,  upon delivery to the Trustees or the Transfer Agent
of a duly executed  instrument  of transfer,  together with such evidence of the
genuineness of each such execution and authorization and of other matters as may
reasonably be required. Upon such delivery the transfer shall be recorded on the
register of the Trust.  Until such  record is made,  the  Shareholder  of record
shall be deemed to be the holder of such Shares for all purposes  hereunder  and
neither the  Trustees  nor any  Transfer  Agent or  registrar  nor any  officer,
employee or agent of the Trust  shall be affected by any notice of the  proposed
transfer.

         Any person becoming entitled to any Shares in consequence of the death,
bankruptcy,  or  incompetence of any  Shareholder,  or otherwise by operation of
law,  shall be recorded  on the  register of Shares as the holder of such Shares
upon production of the proper  evidence  thereof to the Trustees or the Transfer
Agent,  but until such record is made, the Shareholder of record shall be deemed
to be the holder of such  Shares for all  purposes  hereunder  and  neither  the
Trustees  nor any Transfer  Agent or  registrar  nor any officer or agent of the
Trust shall be affected by any notice of such death, bankruptcy or incompetence,
or other  operation of law,  except as may  otherwise be provided by the laws of
the Commonwealth of Massachusetts.

<PAGE>

         SECTION 6.7. NOTICES.  Any and all notices to which any Shareholder may
be entitled and any and all communications  shall be deemed duly served or given
if mailed,  postage prepaid,  addressed to any Shareholder of record at his last
known address as recorded on the register of the Trust.

         SECTION 6.8. VOTING POWERS.  The Shareholders  shall have power to vote
only (i) for the  election of  Trustees as provided in Section 2.2 hereof,  (ii)
with  respect to any  investment  advisory  contract as provided in Section 4.2,
(iii) with respect to  termination of the Trust as provided in Section 9.2, (iv)
with respect to any amendment of the  Declaration  to the extent and as provided
in Section 9.3, (v) with respect to any merger,  consolidation or sale of assets
as provided in Section 9.4, (vi) with respect to  incorporation  of the Trust to
the  extent and as  provided  in Section  9.5,  (vii) to the same  extent as the
stockholders  of a  Massachusetts  business  corporation  as to whether or not a
court action,  proceeding or claim should or should not be brought or maintained
derivatively  or as a class  action on behalf of the Trust or the  Shareholders,
and (viii) with respect to such additional  matters relating to the Trust as may
be required by law,  the  Declaration,  the By-Laws or any  registration  of the
Trust with the Commission (or any successor agency) or any state, or as and when
the  Trustees may consider  necessary  or  desirable.  Each whole Share shall be
entitled  to one vote as to any matter on which it is  entitled to vote and each
fractional Share shall be entitled to a proportionate  fractional  vote,  except
that  Shares  held in the  Treasury  of the  Trust  as of the  record  date,  as
determined  in accordance  with the By-Laws,  shall not be voted and except that
the Trustees may, in conjunction with the establishment of any series or classes
of Shares,  establish conditions under which the several series or classes shall
have separate  voting rights or no voting  rights.  There shall be no cumulative
voting in the  election of Trustees.  Until Shares are issued,  the Trustees may
exercise all rights of Shareholders and may take any action required by law, the
Declaration or the By-Laws to be taken by Shareholders.  The By-Laws may include
further provisions for Shareholders' votes and meetings and related matters.

         SECTION 6.9. SERIES OR CLASSES OF SHARES.  If the Trustees shall divide
the  Shares of the Trust into two or more  series or two or more  classes of any
series,  as provided in Section 6.1 hereof,  the following  provisions  shall be
applicable:

         (a) All provisions  herein relating to the Trust shall apply equally to
         each series of the Trust except as the context otherwise requires.

<PAGE>

         (b) The  number of  authorized  Shares and the number of Shares of each
         series or of each  class  that may be issued  shall be  unlimited.  The
         Trustees may classify or reclassify  any unissued  Shares or any Shares
         previously  issued  and  reacquired  of any series or class into one or
         more  series  or one or  more  classes  that  may  be  established  and
         designated  from time to time. The Trustees may hold as treasury shares
         (of the  same  or  some  other  series  or  class),  reissue  for  such
         consideration  and on such terms as they may  determine,  or cancel any
         Shares  of any  series or any  class  reacquired  by the Trust at their
         discretion from time to time.

         (c) The power of the Trustees to invest and reinvest the Trust Property
         shall be governed by Section 3.2 of this  Declaration  with  respect to
         any one or more series which  represents the interests in the assets of
         the Trust  immediately prior to the establishment of two or more series
         and the power of the Trustees to invest and reinvest assets  applicable
         to any  other  series  shall be as set forth in the  instrument  of the
         Trustees establishing such series.

         (d) All  consideration  received  by the Trust for the issue or sale of
         Shares of a  particular  series or class  together  with all  assets in
         which  such  consideration  is  invested  or  reinvested,  all  income,
         earnings, profits, and proceeds thereof, including any proceeds derived
         from the sale, exchange or liquidation of such assets, and any funds or
         payments  derived from any  reinvestment  of such  proceeds in whatever
         form the same may be, shall irrevocably  belong to that series or class
         for all  purposes,  subject  only to the  rights or  creditors  of such
         series,  and  shall be so  recorded  upon the books of  account  of the
         Trust.  In the event  that  there  are any  assets,  income,  earnings,
         profits, and proceeds thereof, funds, or payments which are not readily
         identifiable  as  belonging  to any  particular  series or  class,  the
         Trustees  shall  allocate  them  among any one or more of the series or
         classes established and designated from time to time in such manner and
         on such  basis  as  they,  in  their  sole  discretion,  deem  fair and
         equitable. Each such allocation by the Trustees shall be conclusive and
         binding  upon  the  Shareholders  of all  series  or  classes  for  all
         purposes.

         (e) The assets  belonging  to each  particular  series shall be charged
         with the  liabilities  of the Trust in respect  of that  series and all
         expenses,  costs, charges and reserves attributable to that series, and
         any general  liabilities,  expenses,  costs, charges or reserves of the
         Trust which are not readily identifiable as belonging to any particular
         series  shall be  allocated  among  the  series  on the  basis of their
         relative  average daily net assets except where  allocations  of direct
         expenses can  otherwise  be fairly made.  The Trustees may from time to
         time in  particular  cases  make  specific  allocations  of  assets  or
         liablilities  among series.  Each allocation of liabilities,  expenses,
         costs,  charges and reserves by the Trustees  shall be  conclusive  and
         binding upon the holders of all series for all  purposes.  The Trustees
         shall have full  discretion,  to the extent not  inconsistent  with the
         1940 Act, to determine which items shall be treated as income and which
         items as capital;  and each such  determination and allocation shall be
         conclusive  and  binding  upon  the  Shareholders.   The  assets  of  a
         particular  series of the Trust shall under no circumstances be charged
         with  liabilities  attributable  to any other series of the Trust.  All
         persons  extending  credit to, or contracting  with or having any claim
         against a particular  series of the Trust shall look only to the assets
         of that  particular  series for  payment of such  credit,  contract  or
         claim.

<PAGE>

         (f) Each Share of a series of the Trust shall  represent  a  beneficial
         interest in the net assets of such  series.  Each holder of Shares of a
         series shall be entitled to receive his pro rata share of distributions
         of income and  capital  gains made with  respect to such  series.  Upon
         redemption of his Shares or indemnification for liabilities incurred by
         reason of his  being or having  been a  Shareholder  of a series,  such
         shareholder  shall be paid solely out of the funds and property of such
         series of the Trust. Upon liquidation or termination of a series of the
         Trust,  Shareholders  of such series shall be entitled to receive a pro
         rata  share  of the net  assets  of such  series.  A  Shareholder  of a
         particular  series of the Trust shall not be entitled to participate in
         a  derivative  or class  action on  behalf  of any other  series or the
         Shareholders of any other series of the Trust.

         (g)   Notwithstanding  any  other  provisions  hereof,  on  any  matter
         submitted  to a vote of  Shareholders  of the Trust,  all  Shares  then
         entitled to vote shall be voted by individual  series,  except that (1)
         when  required by the 1940 Act,  Shares shall be voted in the aggregate
         and not by individual series, and (2) when the Trustees have determined
         that the matter affects only the interests of Shareholders of a limited
         number of series,  then only the  Shareholders  of such series shall be
         entitled to vote thereon.  Classes  within a series shall vote with all
         other  Shares of the series  except that the  Trustees may provide that
         any Class  shall vote  separately  as a Class as to any matter when (i)
         required by law, rule or exemptive order, (ii) they determine that such
         matter affects only the interest of Shares of such Class or affects the
         interests  of Shares of such Class in a manner  different  from that of
         the other Classes or (iii) they  otherwise  determine  that to do so is
         desirable and in the best interests of the  Shareholders  of such Class
         under the circumstances.

         (h) The power of the Trustees to pay dividends  and make  distributions
         shall be governed by Section 8.2 of this  Declaration  with  respect to
         any one or more series or classes which represents the interests in the
         assets of the Trust  immediately  prior to the  establishment of two or
         more  series or  classes.  With  respect to any other  series or class,
         dividends and  distributions on Shares of a particular  series or class
         may be paid with such  frequency as the Trustees may  determine,  which
         may be  daily  or  otherwise,  pursuant  to a  standing  resolution  or
         resolutions  adopted  only once or with such  frequency as the Trustees
         may determine,  to the holders of Shares of that series or class,  from
         such of the income and capital  gains,  accrued or  realized,  from the
         assets  belonging  to  that  series  or  class,  as  the  Trustees  may
         determine, after providing for actual and accrued liabilities belonging
         to that series or class. All dividends and distributions on Shares of a
         particular series or class shall be distributed pro rata to the holders
         of that series or class in  proportion  to the number of Shares of that
         series  or class  held by such  holders  at the date and time of record
         established for the payment of such dividends or distributions.

<PAGE>

         (i) The Trustees  shall have the power to determine  the  designations,
         preferences,  privileges,  limitations and rights, including voting and
         dividend  rights,  of each  class and series of  Shares.  The  Trustees
         (including any successor Trustees) shall have the right at any time and
         from time to time to  reallocate  assets and  expenses or to change the
         designation  of any series now or  hereafter  created,  or to otherwise
         change the special and  relative  rights of any such  series,  provided
         that such change shall not adversely  affect the rights of shareholders
         of a series.

         (j) The  establishment and designation of any series or class of Shares
         shall  be  effective  upon  the  execution  by a  majority  of the then
         Trustees  of  an  instrument   setting  forth  such  establishment  and
         designation  and the relative  rights and preferences of such series or
         class, or as otherwise  provided in such  instrument.  At any time that
         there  are no  Shares  outstanding  of any  particular  series or class
         previously   established  and  designated,   the  Trustees  may  by  an
         instrument  executed by a majority of their number  abolish that series
         or class and the establishment and designation thereof. Each instrument
         referred to in this paragraph  shall have the status of an amendment to
         this Declaration.

                                   ARTICLE VII

                                   REDEMPTIONS


         SECTION 7.1. REDEMPTIONS. All outstanding Shares may be redeemed at the
option of the  holders  thereof,  upon and  subject to the terms and  conditions
provided  in  this  Article  VII.  The  Trust  shall,  upon  application  of any
Shareholder  or  pursuant  to  authorization  from any  Shareholder,  redeem  or
repurchase  from such  Shareholder  outstanding  Shares  for an amount per share
determined  by  the  Trustees  in  accordance   with  any  applicable  laws  and
regulations;  provided  that (a) such amount per share shall not exceed the cash
equivalent of the proportionate interest of each Share of any class or series of
Shares in the  assets of the Trust  attributable  to such class or series at the
time of the  redemption or repurchase  and (b) if so authorized by the Trustees,
the Trust may, at any time and from time to time, charge fees for effecting such
redemption or repurchase, at such rates as the Trustees may establish, as and to
the extent  permitted  under the 1940 Act, and may, at any time and from time to
time, pursuant to the 1940 Act, suspend such right of redemption. The procedures
for and fees, if any,  chargeable in connection  with  effecting and  suspending
redemption  shall be as set forth in the Prospectus  from time to time.  Payment
will be made in such manner as described in the Prospectus.

         SECTION 7.2.  REDEMPTION  OF SHARES;  DISCLOSURE  OF  HOLDINGS.  If the
Trustees  shall, at any time and in good faith, be of the opinion that direct or
indirect  ownership of Shares or other securities of the Trust has or may become
concentrated in any Person to an extent which would  disqualify the Trust or any
series  thereof as a regulated  investment  company  under the Internal  Revenue
Code,  then the  Trustees  shall  have the  power by lot or other  means  deemed
equitable  by them (i) to call for  redemption  by any such Person a number,  or
principal  amount,  of Shares  or other  securities  of the Trust or the  series
sufficient,  in the opinion of the Trustees,  to maintain or bring the direct or
indirect ownership of Shares or other securities of the Trust or the series into
conformity with the  requirements for such  qualification  and (ii) to refuse to
transfer or issue Shares or other  securities  of the Trust or the series to any
Person  whose  acquisition  of the  Shares or other  securities  of the Trust in
question could in the opinion of the Trustees  result in  disqualification.  The
redemption shall be effected at a redemption price determined in accordance with
Section 7.1.

         The  holders of Shares or other  securities  of the Trust or any series
thereof shall upon demand  disclose to the Trustees in writing such  information
with respect to direct and indirect  ownership of Shares or other  securities of
the Trust as the Trustees  deem  necessary to comply with the  provisions of the
Internal  Revenue  Code,  or to  comply  with  the  requirements  of  any  other
authority.

<PAGE>

         SECTION 7.3. REDEMPTIONS OF ACCOUNTS. The Trustees may redeem Shares of
any Shareholder at a redemption  price determined in accordance with Section 7.1
if the aggregate net asset value of the Shares in such Shareholder's  account is
less than an amount set from time to time by the Trustees, subject to such terms
and  conditions as the Trustees may approve,  and subject to the Trust's  giving
general  notice to all  Shareholders  of its  intention  to avail itself of such
right , either by  publication  in the  Trust's  Prospectus,  if any, or by such
means as the Trustees may determine.  Similarly,  the Trustees may redeem Shares
of any  Shareholder at a redemption  price  determined in accordance with 7.1 to
recover  any  account  charges,  as  permitted  by or  disclosed  in the Trust's
Prospectus.

         SECTION  7.4.   REDEMPTIONS   PURSUANT  TO  CONSTANT  NET  ASSET  VALUE
PROVISIONS.  The Trust may also reduce the number of  outstanding  Shares of any
series pursuant to the provisions of Section 8.3.

                                  ARTICLE VIII

                        DETERMINATION OF NET ASSET VALUE,
                          NET INCOME AND DISTRIBUTIONS


         SECTION 8.1. NET ASSET VALUE.  The net asset value of each  outstanding
Share of the Trust shall be determined on such days and at such time or times as
the Trustees may determine. The method of determination of net asset value shall
be determined by the Trustees and shall be as set forth in the  Prospectus.  The
power and duty to make the daily  calculations  may be delegated by the Trustees
to the  Administrator,  the Adviser,  the Custodian,  the Transfer Agent or such
other  person as the  Trustees by  resolution  may  determine.  The Trustees may
suspend the daily  determination  of net asset value to the extent  permitted by
the 1940 Act.

         SECTION 8.2.  DISTRIBUTIONS  TO  SHAREHOLDERS.  The Trustees shall from
time to time distribute  ratably among the  Shareholders  such proportion of the
net profits, surplus (including paid-in surplus), capital, or assets held by the
Trustees  as they  may deem  proper.  Such  distribution  may be made in cash or
property  (including  without limitation any type of obligations of the Trust or
any  assets  thereof),  and  the  Trustees  may  distribute  ratably  among  the
Shareholders additional Shares issuable hereunder in such manner, at such times,
and on such terms as the  Trustees may deem proper.  Such  distributions  may be
among the  Shareholders  of record at the time of  declaring a  distribution  or
among the  Shareholders  of record at the time of  declaring a  distribution  or
among the  Shareholders  of  record at such  later  date as the  Trustees  shall
determine.  The Trustees  may always  retain from the net profits such amount as
they  may  deem  necessary  to pay the  debts or  expenses  attributable  to the
relevant  series of the Trust or to meet  obligations  of such series or as they
may deem  desirable to use in the conduct of its affairs or to retain for future
requirements or extensions of the business.  The Trustees may adopt and offer to
Shareholders  such dividend  reinvestment  plans,  cash dividend payout plans or
related plans as the Trustees shall deem appropriate.

         Inasmuch as the  computation of net income and gains for Federal income
tax  purposes  may vary from the  computation  thereof on the  books,  the above
provisions  shall  be  interpreted  to give  the  Trustees  the  power  in their
discretion  to  distribute  for any fiscal  year as  ordinary  dividends  and as
capital gains  distributions,  respectively,  additional  amounts  sufficient to
enable the Trust to avoid or reduce liability for taxes.

<PAGE>

         SECTION 8.3.  DETERMINATION OF NET INCOME;  CONSTANT NET ASSET VALUE OF
SHARES OF CERTAIN SERIES;  REDUCTION OF OUTSTANDING  SHARES.  The Trustees shall
have the power to  determine  the net income of each  series of the Trust one or
more times on each business day and at each such determination  declare such net
income as dividends in additional  Shares of such series.  The  determination of
net income and the resultant  declaration of dividends  shall be as set forth in
the Prospectus. In the event that any series of the Trust attempts to maintain a
constant net asset value per share of such series,  if, for any reason,  the net
income of such series of the Trust  determined at any time is a negative amount,
the Trustees shall have the power to (i) to offset each  Shareholder's  pro rata
share  of such  negative  amount  from  the  accrued  dividend  account  of such
Shareholder,  or (ii) to reduce the number of outstanding  shares of such series
of the Trust by reducing the number of Shares in the account of such Shareholder
by that number of full and fractional Shares which represents the amount of such
excess negative net income, or (iii) to cause to be recorded on the books of the
Trust an asset account in the amount of such negative net income,  which account
may be reduced by the amount,  provided that the same shall thereupon become the
property  of the Trust and shall not be paid to any  Shareholder,  of  dividends
declared  thereafter  upon the  outstanding  shares on the day such negative net
income is  experienced,  until such asset account is reduced to zero, or (iv) to
combine  the  methods  described  in  clauses  (i) and  (ii)  and  (iii) of this
sentence,  in order to cause the net asset value per Share of such series of the
Trust to remain at a constant amount per  outstanding  share  immediately  after
each such determination and declaration.  The Trustees shall also have the power
to fail to declare a dividend  out of net income for the purposes of causing the
net asset  value per Share of any such  series  to be  increased  to a  constant
amount. The Trustees shall have full discretion to determine whether any cash or
property  received  shall be treated as income or as  principal  and whether any
item of expense  shall be charged to the income or the  principal  account,  and
their   determination   made  in  good  faith  shall  be  conclusive   upon  the
Shareholders.  In the case of stock dividends received,  the Trustees shall have
full discretion to determine, in the light of the particular circumstances,  how
much, if any, of the value thereof shall be treated as income,  the balance,  if
any, to be treated as  principal.  The Trustees  shall not be required to adopt,
but may at any time adopt,  discontinue or amend the practice of maintaining the
net asset value per Share of any series of the Trust at a constant amount.

         SECTION 8.4. POWER TO MODIFY FOREGOING PROCEDURES.  Notwithstanding any
of the foregoing provisions of this Article VIII, the Trustees may prescribe, in
their absolute  discretion,  such other bases and times for  determining the per
Share net  asset  value of the  Shares or net  income,  or the  declaration  and
payment of dividends and distributions,  as they may deem necessary or desirable
to enable the Trust to comply with any provisions of the 1940 Act, including any
rule or  regulation  adopted  pursuant  to  Section  22 of the  1940  Act by the
Commission  or  any  securities  association  registered  under  the  Securities
Exchange Act of 1934, or any order of exemption issued by said  Commission,  all
as in  effect  now or  hereafter  amended  or  modified.  Without  limiting  the
generality of the  foregoing,  the Trustees may  establish  classes or series of
Shares in accordance with Section 6.9.

                                   ARTICLE IX

                         DURATION; TERMINATION OF TRUST;
                            AMENDMENT; MERGERS, ETC.


         SECTION 9.1 DURATION.  The Trust shall continue  without  limitation of
time but subject to the provisions of this Article IX.

         SECTION 9.2.  TERMINATION OF TRUST. (a) The Trust may be terminated (i)
by the affirmative vote of the holders of not less than two-thirds of the Shares
outstanding and entitled to vote at any meeting of  Shareholders,  or (ii) by an
instrument in writing,  without a meeting,  signed by a majority of the Trustees
and consented to by the holders of not less than  two-thirds of such Shares,  or
by such other vote as may be  established  by the  Trustees  with respect to any
class or series of Shares,  or (iii) by the  Trustees  by written  notice to the
Shareholders. Upon the termination of the Trust:

         (i) The Trust  shall  carry on no  business  except for the  purpose of
         winding up its affairs.

         (ii) The Trustees shall proceed to wind up the affairs of the Trust and
         all of the powers of the Trustees under this Declaration shall continue
         until the affairs of the Trust shall have been wound up,  including the
         power to fulfill or discharge the  contracts of the Trust,  collect its
         assets, sell, convey, assign,  exchange,  transfer or otherwise dispose
         of all or any  part  of the  remaining  Trust  Property  to one or more
         persons at public or private sale for  consideration  which may consist
         in whole or in part of cash,  securities or other property of any kind,
         discharge or pay its liabilities,  and to do all other acts appropriate
         to  liquidate  its  business;   provided  that  any  sale,  conveyance,
         assignment,   exchange,   transfer  or  other  disposition  of  all  or
         substantially all the Trust Property shall require Shareholder approval
         in accordance with Section 9.4 hereof.

         (iii)  After  paying or  adequately  providing  for the  payment of all
         liabilities,  and  upon  receipt  of  such  releases,  indemnities  and
         refunding agreements, as they deem necessary for their protection,  the
         Trustees may distribute  the remaining  Trust  Property,  in cash or in
         kind  or  partly  each,  among  the  Shareholders  according  to  their
         respective rights.

         (b) After termination of the Trust and distribution to the Shareholders
         as herein provided,  a majority of the Trustees shall execute and lodge
         among the records of the Trust an instrument  in writing  setting forth
         the fact of such  termination,  and the  Trustees  shall  thereupon  be
         discharged from all further  liabilities and duties hereunder,  and the
         rights and interests of all Shareholders shall thereupon cease.

<PAGE>

         SECTION 9.3. AMENDMENT  PROCEDURE.  (a) This Declaration may be amended
by a Majority  Shareholder  Vote.  The Trustees may also amend this  Declaration
without the vote or consent of  Shareholders to change the name of the Trust, to
supply any omission, to cure, correct or supplement any ambiguous,  defective or
inconsistent  provision  hereof,  or if they deem it  necessary  to conform this
Declaration  to the  requirements  of, or to reduce or eliminate  the payment of
taxes by the Trust or any series thereof under applicable  federal or state laws
or  regulations  or  the  requirements  of  the  regulated   investment  company
provisions of the Internal  Revenue Code,  but the Trustees  shall not be liable
for failing so to do.

         (b) No amendment  may be made under this Section 9.3 which would change
any  rights  with  respect  to any  Shares of the Trust by  reducing  the amount
payable  thereon upon  liquidation of the Trust or by diminishing or eliminating
any voting  rights  pertaining  thereto,  except with the vote or consent of the
holders of two-thirds of the Shares outstanding and entitled to vote, or by such
other vote as may be  established  by the Trustees with respect to any series or
class  of  Shares.  Nothing  contained  in this  Declaration  shall  permit  the
amendment of this Declaration to impair the exemption from personal liability of
the Shareholders,  Trustees,  officers,  employees and agents of the Trust or to
permit assessments upon Shareholders.

         (c) A certificate  signed by a majority of the Trustees or by Secretary
or any Assistant Secretary of the Trust, setting forth an amendment and reciting
that it was duly adopted by the  Shareholders or by the Trustees as aforesaid or
a copy of the  Declaration,  as  amended,  and  executed  by a  majority  of the
Trustees or certified by the Secretary or any Assistant  Secretary of the Trust,
shall be conclusive  evidence of such amendment when lodged among the records of
the Trust.

         Notwithstanding  any  other  provision  hereof,  until  such  time as a
Registration  Statement  under the Securities Act of 1933, as amended,  covering
the  first  public  offering  of  securities  of the  Trust  shall  have  become
effective,  this  Declaration may be terminated or amended in any respect by the
affirmative  vote of a majority of the Trustees or by an instrument  signed by a
majority of the Trustees.

         SECTION 9.4. MERGER,  CONSOLIDATION  AND SALE OF ASSETS.  The Trust may
merge or consolidate  with any other  corporation,  association,  trust or other
organization  or may sell,  lease or exchange  all or  substantially  all of the
Trust Property,  including its goodwill,  upon such terms and conditions and for
such consideration when and as authorized, at any meeting of Shareholders called
for the  purpose,  by the  affirmative  vote of the  holders  of not  less  than
two-thirds of the Shares  outstanding  and entitled to vote, or by an instrument
or instruments in writing without a meeting,  consented to by the holders of not
less than two-thirds of such Shares, or by such other vote as may be established
by the  Trustees  with  respect  to any  series  or class of  Shares;  provided,
however,  that,  if such  merger,  consolidation,  sale,  lease or  exchange  is
recommended  by the Trustees,  a Majority  Shareholder  Vote shall be sufficient
authorization; and any such merger, consolidation, sale, lease or exchange shall
be deemed for all purposes to have been  accomplished  under and pursuant to the
statutes of the  Commonwealth of  Massachusetts.  In respect of any such merger,
consolidation,  sale or exchange of assets, any Shareholder shall be entitled to
rights of  appraisal  of his  Shares to the same  extent as a  shareholder  of a
Massachusetts business corporation in respect of a merger,  consolidation,  sale
or exchange of assets of a Massachusetts  business corporation,  and such rights
shall be his exclusive remedy in respect of his dissent from any such action.

<PAGE>

         SECTION 9.5.  INCORPORATION.  With  approval of a Majority  Shareholder
Vote, or by such other vote as may be  established  by the Trustees with respect
to any series or class of Shares,  the  Trustees  may cause to be  organized  or
assist  in  organizing  a  corporation  or  corporations  under  the laws of any
jurisdiction or any other trust, partnership,  association or other organization
to take over all of the Trust  Property or to carry on any business in which the
Trust shall directly or indirectly  have any interest,  and to sell,  convey and
transfer  the Trust  Property to any such  corporation,  trust,  association  or
organization in exchange for the shares or securities thereof or otherwise,  and
to lend money to,  subscribe for the shares or securities of, and enter into any
contracts  with  any  such  corporation,  trust,  partnership,   association  or
organization in which the Trust holds or is about to acquire shares or any other
interest.  The  Trustees  may also cause a merger or  consolidation  between the
Trust  or any  successor  thereto  any  such  corporation,  trust,  partnership,
association  or other  organization  if and to the extent  permitted  by law, as
provided  under  the law  then in  effect.  Nothing  contained  herein  shall be
construed as requiring  approval of Shareholders for the Trustees to organize or
assist  in  organizing   one  or  more   corporations,   trusts,   partnerships,
associations  or other  organizations  and selling,  conveying or transferring a
portion of the Trust Property to such organizations or entities.

                                    ARTICLE X

                             REPORTS TO SHAREHOLDERS


         The Trustees shall at least semi-annually  submit to the Shareholders a
written financial report of the transactions of the Trust,  including  financial
statements  which shall at least  annually be  certified by  independent  public
accountants.

                                   ARTICLE XI

                                  MISCELLANEOUS


         SECTION 11.1.  FILING.  This Declaration and any amendment hereto shall
be filed in the office of the Secretary of the Commonwealth of Massachusetts and
in such other places as may be required under the laws of Massachusetts  and may
also be filed or recorded in such other places as the Trustees deem appropriate.
Each  amendment  so filed  shall be  accompanied  by a  certificate  signed  and
acknowledged by a Trustee or by the Secretary or any Assistant  Secretary of the
Trust stating that such action was duly taken in a manner provided  herein,  and
unless such  amendment  or such  certificate  sets forth some later time for the
effectiveness  of such  amendment,  such  amendment  shall be effective upon its
filing. A restated Declaration,  integrating into a single instrument all of the
provisions of the  Declaration  which are then in effect and  operative,  may be
executed from time to time by a majority of the Trustees and shall,  upon filing
with the Secretary of the Commonwealth of Massachusetts,  be conclusive evidence
of all amendments contained therein and may thereafter be referred to in lieu of
the original Declaration and the various amendments thereto.

         SECTION 11.2. RESIDENT AGENT. The name of the Trust's resident agent is
CT Corporation  System, and its post office address is 2 Oliver Street,  Boston,
Massachusetts 02109.

         SECTION  11.3.  GOVERNING  LAW.  This  Declaration  is  executed by the
Trustees with reference to the laws of the  Commonwealth of  Massachusetts,  and
the rights of all parties and the validity and  construction  of every provision
hereof shall be subject to and construed according to the laws of said State.

         SECTION  11.4.  COUNTERPARTS.  The  Declaration  may be  simultaneously
executed  in  several  counterparts,  each of  which  shall be  deemed  to be an
original,  and such  counterparts,  together,  shall constitute one and the same
instrument,   which  shall  be  sufficiently  evidenced  by  any  such  original
counterpart.

         SECTION 11.5. RELIANCE BY THIRD PARTIES. Any certificate executed by an
individual who,  according to the records of the Trust,  appears to be a Trustee
hereunder,  or Secretary or Assistant Secretary of the Trust, certifying to: (a)
the number or identity of Trustees or Shareholders, (b) the due authorization of
the execution of any instrument or writing, (c) the form of any vote passed at a
meeting of Trustees or Shareholders, (d) the fact that the number of Trustees or
Shareholders  present  at  any  meeting  or  executing  any  written  instrument
satisfies  the  requirements  of this  Declaration,  (e) the form of any By-Laws
adopted by or the identity of any officers  elected by the Trustees,  or (f) the
existence of any fact or facts which in any manner  relate to the affairs of the
Trust,  shall be conclusive  evidence as to the matters so certified in favor of
any Person dealing with the Trustees and their successors.

<PAGE>

         SECTION 11.6. PROVISIONS IN CONFLICT WITH LAWS OR REGULATIONS.  (a) The
provisions  of  the  Declaration  are  severable,  and  if  the  Trustees  shall
determine,  with  the  advice  of  counsel,  that any of such  provisions  is in
conflict with the 1940 Act, the regulated  investment  company provisions of the
Internal  Revenue  Code or with  other  applicable  laws  and  regulations,  the
conflicting  provisions  shall be deemed never to have constituted a part of the
Declaration;  provided, however, that such determination shall not affect any of
the remaining  provisions of the  Declaration  or render invalid or improper any
action taken or omitted prior to such determination.

         (b) If any  provision  of the  Declaration  shall  be held  invalid  or
unenforceable in any  jurisdiction,  such invalidity or  unenforceability  shall
attain only to such provision in such  jurisdiction  and shall not in any manner
affect such provision in any other  jurisdiction  or any other  provision of the
Declaration in any jurisdiction.

                                    ARTICLE I

                                  SHAREHOLDERS

         SECTION 1. PLACE OF MEETING.  All meetings of the Shareholders shall be
held at the principal  office of the Trust in the  Commonwealth of Massachusetts
or at such other  place  within  the  United  States as may from time to time be
designated by the Trustees and stated in the notice of such meeting.

         SECTION 2. SPECIAL OR EXTRAORDINARY MEETINGS.  Special or extraordinary
meetings of the  Shareholders  for any purpose or purposes  may be called by the
Chairman or a majority  of the  Trustees,  and shall be called by the  Secretary
upon receipt of the request in writing signed by  Shareholders  holding not less
than  twenty-five  per cent  (25%) of the  Shares  issued  and  outstanding  and
entitled to vote  thereat.  Such request  shall state the purpose or purposes of
the  proposed  meeting.  The  Secretary  shall inform such  Shareholders  of the
reasonably  estimated  costs of preparing and mailing such notice of meeting and
upon payment to the Trust of such costs, the Secretary shall give notice stating
the purpose or purposes of the meeting as required in this Article and By-Law to
all Shareholders  entitled to notice of such meeting. No special meeting need be
called upon the  request of the  holders of Shares  entitled to cast less than a
majority of all votes entitled to be cast at such meeting to consider any matter
which is substantially the same as a matter voted upon at any special meeting of
Shareholders held during the preceding twelve months.

         SECTION  3.  NOTICE OF  MEETINGS.  Not less than ten days' or more than
ninety days' written or printed notice of every meeting of Shareholders, stating
the time and place thereof (and the general  nature of the business  proposed to
be transacted at any special or extraordinary  meeting),  shall be given to each
Shareholder  entitled  to vote  thereat by  leaving  the same with him or at his
residence  or usual  place of  business  by mailing  it,  postage  prepaid,  and
addressed  to him at his address as it appears  upon the books of the Trust.  If
mailed,  notice shall be deemed to be given when  deposited in the United Stated
mail addressed to the Shareholder as aforesaid.

         No notice of the time,  place or purpose of any meeting of Shareholders
need be given to any  Shareholder  who  attends  in person or by proxy or to any
Shareholder who executes a written waiver of such notice, either before or after
the meeting is held, and which notice is filed with the records of the meeting.

         SECTION 4. RECORD DATES.  The Trustees may fix, in advance,  a date not
more  than  ninety  (90) or less than ten (10)  days  preceding  the date of any
meeting  of  Shareholders  as  a  record  date  for  the  determination  of  the
Shareholders  entitled  to  notice  of and to  vote at such  meeting;  and  only
Shareholders  of record on such date shall be  entitled to notice of and to vote
at such meeting.

         SECTION 5. QUORUM AND  ADJOURNMENT OF MEETINGS.  The presence in person
or by proxy of the  holders of record of a  majority  of the Shares of the Trust
issued and outstanding and entitled to vote thereat shall constitute a quorum at
<PAGE>

all meetings of the Shareholders except as otherwise provided in the Declaration
of Trust.  If,  however,  such quorum shall not be present or represented at any
meeting of the Shareholders,  the holders of a majority of the Shares present in
person or by proxy shall have power to adjourn  the  meeting  from time to time,
without  notice  other than  announcement  at the meeting,  until the  requisite
amount of Shares  entitled to vote at such  meeting  shall be  present.  At such
adjourned  meeting  at which the  requisite  amount of Shares  entitled  to vote
thereat shall be  represented  any business may be  transacted  which might have
been transacted at the meeting as originally notified.

         SECTION 6. VOTING AND  INSPECTORS.  At all  meetings,  Shareholders  of
record  entitled to vote thereat shall have one vote for each Share  standing in
his name on the books of the  Trust  (and such  Shareholders  of record  holding
fractional shares, if any, shall have  proportionate  voting rights) on the date
of the determination of Shareholders entitled to vote at such meeting, either in
person  or by proxy  appointed  by  instrument  in  writing  subscribed  by such
Shareholder  or his duly  authorized  attorney.  No proxy shall be valid  eleven
months after its date.  Pursuant to a resolution  of a majority of the Trustees,
proxies may be solicited in the name of one or more  Trustees or officers of the
Trust.

         All elections  shall be had and all questions  decided by a majority of
the votes cast at a duly constituted  meeting,  except as otherwise  provided by
statute or by the Declaration of Trust or by these By-Laws.

         At any election of Trustees,  the Chairman of the meeting may, and upon
the request of the holders of ten percent  (10%) of the Shares  entitled to vote
at such  election  shall,  appoint two  inspectors  of election  who shall first
subscribe an oath or affirmation to execute  faithfully the duties of inspectors
at such  election  with strict  impartiality  and according to the best of their
ability,  and shall after the election make a  certificate  of the result of the
vote taken.
No candidate for the office of Trustee shall be appointed such inspector.

         SECTION 7. CONDUCT OF MEETINGS.  The meetings of the Shareholders shall
be presided over by the Chairman, or if he is not present, by the President,  or
if none of them is  present,  by a Chairman  to be elected at the  meeting.  The
Secretary of the Trust,  if present,  shall act as a Secretary of such meetings,
or if he is not  present,  an Assistant  Secretary  shall so act; if neither the
Secretary nor any Assistant  Secretary is present,  then the meeting shall elect
its Secretary.

         SECTION 8.  CONCERNING  VALIDITY  OF  PROXIES,  BALLOTS,  ETC. At every
meeting of the  Shareholders,  all proxies shall be required and taken in charge
of and all ballots  shall be required  and  canvassed  by the  Secretary  of the
meeting,  who shall decide all questions  touching the  qualification of voters,
the validity of the proxies and the  acceptance  or  rejection of votes,  unless
inspectors of election shall have been appointed by the Chairman of the meeting,
in which event such inspectors of election shall decide all such questions.

         SECTION 9. ACTION  WITHOUT  MEETINGS.  Except as otherwise  provided by
law, the  provisions  of these  By-Laws  relating to notices and meetings to the
contrary  notwithstanding,  any action  required or permitted to be taken at any
meeting of  Shareholders  may be taken  without a meeting  if a majority  of the
Shareholders  entitled to vote upon the action  consent to the action in writing

                                       2
<PAGE>

and such consents are filed with the records of the Trust. Such consent shall be
treated for all purposes as a vote taken at a meeting of Shareholders.


                                   ARTICLE II

                                    TRUSTEES

         SECTION 1. NUMBER AND TENURE OF OFFICE. The property of the Trust shall
be  controlled  by and the  business and affairs of the Trust shall be conducted
and managed by not less than two (2) or more than thirteen (13) Trustees, as may
be fixed from time to time by a written  instrument  signed by a majority of the
Trustees then in office. Trustees need not be Shareholders. The tenure of office
of each Trustee  shall be set by  resolution  of the  Trustees,  except that any
Trustee may resign his office or be removed  from  office for cause  pursuant to
the provisions of the Declaration of Trust.

         SECTION 2.  VACANCIES.  In the case of any vacancy or  vacancies in the
office of Trustee  through  death,  resignation  or other  cause,  other than an
increase  in the  number of  Trustees,  a  majority  of the  remaining  Trustees
although a majority is less than a quorum,  by an affirmative  vote, or the sole
remaining Trustee,  may elect a successor or successors,  as the case may be, to
hold office.

         SECTION 3. INCREASE OR DECREASE IN NUMBER OF  DIRECTORS.  The Trustees,
by the vote of a majority of all the Trustees  then in office,  may increase the
number of Trustees and may elect  Trustees to fill the vacancies  created by any
such increase in the number of Trustees. The Trustees, by the vote of a majority
of all the Trustees then in office, may likewise decrease the number of Trustees
to a number not less than two.

         SECTION 4 PLACE OF MEETING. The Trustees may hold their meetings,  have
one or more offices,  and keep the books of the Trust,  outside the Commonwealth
of Massachusetts, at any office or offices of the Trust or at any other place as
they may from time to time by resolution determine,  or in the case of meetings,
as they may from time to time by  resolution  determine or as shall be specified
or fixed in the respective notices or waivers of notice thereof.

         SECTION 5. REGULAR MEETINGS.  Regular meetings of the Trustees shall be
held at such  time and on such  notice  as the  Trustees  may from  time to time
determine.

         SECTION 6. SPECIAL  MEETINGS.  Special  meetings of the Trustees may be
held from time to time upon call of the  Chairman,  the Secretary or two or more
of the Trustees, by oral or telegraphic or written notice duly served on or sent
or mailed to each Trustee not less than one day before such  meeting.  No notice
of any special  meeting need be given to any Trustee who attends in person or to
any Trustee who executes a written waiver of such notice, either before or after
the meeting is held,  and which notice is filed with the records of the meeting.
Such  notice or waiver of notice  need not state the purpose or purposes of such
meeting.

         SECTION 7.  QUORUM.  One-third  of the  Trustees  then in office  shall
constitute  a quorum for the  transaction  of business,  provided  that a quorum
shall in no case be less than two Trustees.  If at any meeting of Trustees there
shall be less than a quorum present, a majority of those present may adjourn the
meeting  from time to time until a quorum shall have been  obtained.  The act of
the majority of the  Trustees  present at any meeting at which there is a quorum

                                       3
<PAGE>

shall be the act of the Trustees,  except as otherwise  specifically provided by
statute or by the Declaration of Trust or by these By-Laws.

         SECTION 8.  COMMITTEES.  The Trustees,  by the majority vote of all the
Trustees then in office, may appoint from the Trustees committees which shall in
each case consist of such number of Trustees  (not less than two) and shall have
and may exercise  such powers as the Trustees  may  determine in the  resolution
appointing  them.  A  majority  of all the  members  of any such  committee  may
determine  its  action  and fix the time and place of its  meetings,  unless the
Trustees shall otherwise  provide.  The Trustees shall have power at any time to
change the members and powers of any such  committee,  to fill  vacancies and to
discharge any such committee.

         SECTION 9. TELEPHONE MEETINGS.  Trustees or a committee of the Trustees
may  participate  in a meeting  by means of a  conference  telephone  or similar
communications  equipment if all persons  participating  in the meeting can hear
each  other  at the  same  time.  Participation  in a  meeting  by  these  means
constitute presence in person at the meeting.

         SECTION 10. ACTION WITHOUT A MEETING.  Any action required or permitted
to be taken at any meeting of the Trustees or any committee thereof may be taken
without a  meeting,  if a written  consent  to such  action is signed by all the
Trustees  then in office or all members of such  committee,  as the case may be,
and such  written  consent is filed with the minutes of the  proceedings  of the
Trustees or committee.

         SECTION 11. COMPENSATION. No Trustee shall receive any stated salary or
fees from the Trust for his services as such if such trustee is,  otherwise than
by reason of being such Trustee,  an interested  person (as such term is defined
by the Investment Company Act of 1940) of the Trust or of its investment adviser
or principal underwriter. Except as provided in the preceding sentence, Trustees
shall be entitled to receive such compensation from the Trust for their services
as may from time to time be voted by the Trustees.

                                   ARTICLE III

                                    OFFICERS

         SECTION 1.  EXECUTIVE  OFFICERS.  The  executive  officers of the Trust
shall be chosen by the Trustees.  These shall include a Chairman (who shall be a
Trustee),  a President,  one or more Vice  Presidents  (the number thereof to be
determined by the Trustees), a Secretary and a Treasurer.  The Trustees may also
in their discretion  appoint  Assistant  Secretaries,  Assistant  Treasurers and
other officers,  agents and employees, who shall have such authority and perform
such duties as the  Trustees  may  determine.  The Trustees may fill any vacancy
which may occur in any office. Any two offices, except those of Chairman and any
President,  may be  held by the  same  person,  but no  officer  shall  execute,
acknowledge  or  verify  any  instrument  in more  than  one  capacity,  if such
instrument is required by law or these By-Laws to be executed,  acknowledged  or
verified by two or more officers.

         SECTION 2. TERM OF OFFICE.  The term of office of all officers shall be
one year and until their  respective  successors are chosen and  qualified.  Any
officer may be removed from office at any time with or without cause by the vote
of a majority of all the Trustees then in office.

                                       4
<PAGE>

         SECTION 3. POWERS AND DUTIES. The officers of the Trust shall have such
powers and duties as generally pertain to their respective  offices,  as well as
such powers and duties as may from time to time be conferred by the Trustees.

                                   ARTICLE IV

                                 SHARE INTERESTS

         SECTION 1.  CERTIFICATES  FOR SHARES.  Shareholders are not entitled to
receive certificates evidencing their Share ownership, unless the Trustees shall
by resolution otherwise determine.

         SECTION  2.   TRANSFER  OF  SHARES.   Shares  of  the  Trust  shall  be
transferable  on the register of the Trust by the holder thereof in person or by
his agent duly  authorized  in writing,  upon  delivery  to the  Trustees or the
Transfer  Agent of a duly executed  instrument  of transfer,  together with such
evidence of the  genuineness  of each such execution and  authorization  of such
other matters as the Trust or its agents may reasonably require.

         SECTION 3. REGISTER OF SHARES. A register of the Trust,  containing the
names and  addresses of the  Shareholders  and the number of Shares held by them
respectively  and a  record  of all  transfers  thereof,  shall  be  kept at the

offices of the Transfer Agent of the Trust.

                                      SEAL

         The Trustees may provide for a suitable  seal, in such form and bearing

                                   ARTICLE VI

                                   FISCAL YEAR

      The fiscal  year of the Trust  shall begin on the first day of January and
shall end on the last day of December in each year.

                                   ARTICLE VII

                                 INDEMNIFICATION

         A  representative  of the Trust shall be  indemnified by the Trust with
respect to each  proceeding  against  such  representative,  except a proceeding
brought by or on behalf of the Trust,  against  expenses  (including  attorneys'
fees),  judgments,  fines and amounts paid in settlement actually and reasonably
incurred by such  representative  in connection with such  proceeding,  provided
that such  representative  to be in or not opposed to the best  interests of the

                                       5

Trust and, with respect to any criminal  proceeding,  had no reasonable cause to
believe his conduct was unlawful. The termination of any proceeding by judgment,
order,  settlement,  conviction  or  upon  a  plea  of  nolo  contendere  or its
equivalent,  shall not, of itself,  create a presumption that the person did not
act in good faith in a manner which reasonably  believed to be in or not opposed
to the best interests of the Trust and, with respect to any criminal proceeding,
had reasonable cause to believe that his conduct was unlawful.

         A representative  of the Trust shall be indemnified by the Trust,  with
respect  to each  proceeding  brought  by or on  behalf of the Trust to obtain a
judgment or decree in its favor,  against expenses  (including  attorneys' fees)
actually  and  reasonably  incurred  by him in  connection  with the  defense or
settlement  of such  proceeding,  if he acted in good  faith  and in a manner he
reasonably  believed to be in or not opposed to the best interests of the Trust;
except that no indemnification  shall be made in respect of any claim, issue, or
matter as to which  such  representative  has been  adjudged  to be  liable  for
negligence or misconduct in the performance of his duty to the Trust, unless and
only to the extent  that the court in which the  proceeding  was  brought,  or a
court of equity in the  county  in which  the  Trust has its  principal  office,
determines upon application  that,  despite the adjudication of liability but in
view of all  circumstances of the case, such corporate  representative is fairly
and reasonably  entitled to indemnity for the expenses which the court considers
proper.

         To the extent that the  representative of the Trust has been successful
on the  merits or  otherwise  in defense of any  proceeding  referred  to in the
preceding two paragraphs,  or in defense of any claim,  issue or matter therein,
the Trust shall indemnify him against all expenses  (including  attorneys' fees)
actually and reasonably incurred by him in connection therewith.

         Except as provided in the preceding paragraph any indemnification under
the first two  paragraphs of this Article  (unless  ordered by a court) shall be
made by the Trust only as authorized  in the specific case upon a  determination
that  indemnification  of the  representative  of the  Trust  is  proper  in the
circumstances because he has met the applicable standard of conduct set forth in
such  paragraphs.  The  determination  shall  be made (1) by the  Trustees  by a
majority  vote of a quorum  consisting  of Trustees  who were not parties to the
proceeding, or (2) if a quorum is not obtainable or if a quorum of disinterested
Trustees so directs,  by independent legal counsel in a written opinion,  or (3)
by the Shareholders.

         Expenses (including attorneys' fees) incurred in defending a proceeding
may be paid by the Trust in  advance  of the final  disposition  thereof  if (1)
authorized by the Trustees in the specific  case,  and (2) the Trust receives an
undertaking  by or on  behalf  of the  representative  of the Trust to repay the
advance if it is not ultimately determined that he is entitled to be indemnified
by the Trust as authorized in this Article.

         The  indemnification  provided  by this  Article  shall  not be  deemed
exclusive  of any other rights to which a  representative  of the Trust or other
person  may  be  entitled  under  any  agreement,   vote  of   Shareholders   or
disinterested Trustees or otherwise,  both as to action in his official capacity
and as to action  in  another  capacity  while  holding  the  office,  and shall
continue  as to a person who has ceased to be a Trustee,  officer,  employee  or
agent and inure to the benefit of his heirs and personal representatives.

         The Trust may purchase  and maintain  insurance on behalf of any person
who is or was a Trustee,  officer,  employee or agent of the Trust, or is or was
serving at the request of the Trust as a trustee, director, officer, employee or

                                       6
<PAGE>

agent  of  another  trust,  corporation,  partnership,  joint  venture  or other
enterprise against any liability asserted against him and incurred by him in any
such  capacity or arising out of his status as such,  regardless  of whether the
Trust would have the power to  indemnify  him against  the  liability  under the
provisions of this Article.

         Nothing  contained in the Section  shall be construed to indemnify  any
representative  of the  Trust  against  any  liability  to the  Trust  or to its
security   holders  to  which  he  would  otherwise  be  subject  by  reason  of
misfeasance,  bad faith,  gross  negligence or reckless  disregard of the duties
involved in the conduct of his office.

         As  used  in  this  Article  "representative  of the  Trust"  means  an
individual (1) who is a present or former Trustee, officer, agent or employee of
the Trust or who serves or has served  another trust  corporation,  partnership,
joint venture or other  enterprise  in one of such  capacities at the request of
the Trust,  and (2) who by reason of his position is, has been or is  threatened
to be made a party to a proceeding;  and  "proceeding"  includes any threatened,
pending or  completed  action,  suit or  proceeding,  whether  civil,  criminal,
administrative or investigative.

                                  ARTICLE VIII

                                    CUSTODIAN

         SECTION 1. The Trust shall have as custodian or custodians  one or more
trust  companies or banks of good standing,  each having a capital,  surplus and
undivided profits aggregating not less than fifty million dollars ($50,000,000),
and, to the extent required by the Investment Company Act of 1940, the funds and
securities  held by the Trust  shall be kept in the  custody of one or more such
custodians, provided such custodian or custodians can be found ready and willing
to act, and further  provided that the Trust may use as  subcustodians,  for the
purpose of holding any foreign  securities  and related  funds of the Trust such
foreign banks as the Trustees may approve and as shall be permitted by law.

         SECTION 2. The Trust shall upon the  resignation  or inability to serve
of its custodian or upon change of the custodian:

            (i)   in case of such  resignation  or inability  to serve,  use its
                  best efforts to obtain a successor custodian;

            (ii)  require  that the cash and  securities  owned by the  Trust be
                  delivered directly to the successor custodian; and

            (iii) in the event that no successor  custodian can be found, submit
                  to the Shareholders before permitting delivery of the cash and
                  securities  owned by the Trust  otherwise  than to a successor
                  custodian,  the question whether the Trust shall be liquidated
                  or shall function without a custodian.

                                   ARTICLE IX

                       REMOVAL OF TRUSTEES BY SHAREHOLDERS

         SECTION 1.  REMOVAL BY  SHAREHOLDERS.  No person shall serve as Trustee
after the  holders  of record of not less  than  two-thirds  of the  outstanding
shares of  beneficial  interest  in the Trust  (without  regard to Series)  have
declared  that he be removed from the office  either by  declaration  in writing
filed with the  Secretary of the Trust or by votes cast in person or by proxy at
a meeting called for the purpose.

         SECTION 2.  MEETING.  The  Trustees  shall  promptly  call a meeting of
shareholders  for the  purpose  of voting  upon the  question  of removal of any
Trustee or Trustees when  requested in writing so to do by the record holders of
not less than 10 per centum of outstanding shares.

         SECTION 3. PROCEDURES.  Whenever ten or more Shareholders of record who
have been such for at least six months  preceding the date of  application,  and
who hold in the  aggregate  either  shares  having a net asset value of at least
$25,000 or at least 1 per centum of the outstanding  shares,  whichever is less,
shall apply to the Trustees in writing,  stating  that they wish to  communicate
with other  shareholders with a view to obtaining  signatures to a request for a
meeting  pursuant to this Article IX and accompanied by a form of  communication
and request which they wish to transmit, the Trustees shall within five business
days after receipt of such applications either --

            (1)   afford to such applications  access to a list of the names and
                  addresses of all  Shareholders as recorded on the books of the
                  Trust; or

            (2)   inform  such  applicants  as  to  the  approximate  number  of
                  Shareholders of record and the approximate  cost of mailing to
                  them the proposed communications and form of request.

            (3)   If the  Trustees  elect to  follow  the  course  specified  in
                  paragraph (2) of Section (3) of this Article IX, the Trustees,
                  upon the written request of such applicants,  accompanied by a
                  tender  of the  material  to be mailed  and of the  reasonable
                  expenses of mailing,  shall, with reasonable promptness,  mail
                  such material to all Shareholders of record at their addresses
                  as recorded on the books,  unless  within five  business  days
                  after such the Trustees shall mail to such applicants and file
                  with the Securities and Exchange Commission (the "Commission")
                  together  with a copy of the material to be mailed,  a written
                  statement signed by at least a majority of the Trustees to the
                  effect that in their  opinion  either such  material  contains
                  untrue statements of fact or omits to state facts necessary to
                  make the statements contained therein not misleading, or would
                  be in violation of applicable law, and specifying the basis of
                  such  opinion.  The  trustees  shall  have a right to demand a
                  hearing before the Commission with regard to such material and
                  shall comply with an order of the Commission relating thereto.

                         SELIGMAN GROUP OF MUTUAL FUNDS

               PLAN FOR MULTIPLE CLASSES OF SHARES (THREE CLASSES)


         THIS  PLAN,  as it may be  amended  from time to time,  sets  forth the
separate  arrangement and expense allocation of each class of shares (a "Class")
of each registered open-end management investment company, or series thereof, in
the Seligman Group of Mutual Funds that offers multiple classes of shares (each,
a  "Fund").  The Plan has been  adopted  pursuant  to Rule  18f-3(d)  under  the
Investment  Company Act of 1940,  as amended (the  "Act"),  by a majority of the
Board of Directors or Trustees, as applicable ("Directors"), of each Fund listed
on  Schedule  I  hereto,  including  a  majority  of the  Directors  who are not
interested  persons of such Fund within the  meaning of Section  2(a)(19) of the
Act ("Disinterested  Directors"). Any material amendment to this Plan is subject
to the  prior  approval  of the  Board  of  Directors  of each  Fund to which it
relates, including a majority of the Disinterested Directors.

1. GENERAL

      A.    Any Fund may issue  more than one  Class of voting  stock,  provided
            that each Class:

            i.    Shall have a different arrangement for shareholder services or
                  the  distribution  of securities or both, and shall pay all of
                  the expenses of that arrangement;

            ii.   May pay a different  share of other  expenses,  not  including
                  advisory or custodial  fees or other  expenses  related to the
                  management  of  the  Fund's  assets,  if  these  expenses  are
                  actually  incurred in a different  amount by that Class, or if
                  the  Class  receives  services  of a  different  kind  or to a
                  different  degree than other  Classes of the same Fund ("Class
                  Level Expenses");

            iii.  May  pay a  different  advisory  fee to the  extent  that  any
                  difference in amount paid is the result of the  application of
                  the same  performance fee provisions in the advisory  contract
                  of the Fund to the different  investment  performance  of each
                  Class;

            iv.   Shall have exclusive  voting rights on any matter submitted to
                  shareholders that relates solely to its arrangement;

                                      -1-
<PAGE>


            v.    Shall have separate  voting rights on any matter  submitted to
                  shareholders  in which the  interests of one Class differ from
                  the interests of any other Class; and

            vi.   Shall  have  in  all  other   respects  the  same  rights  and
                  obligations as each other Class of the Fund.

      B.    i.    Except as  expressly  contemplated  by this  paragraph  B., no
                  types or  categories  of expenses  shall be  designated  Class
                  Level Expenses.

            ii.   The  Directors  recognize  that  certain  expenses  arising in
                  certain sorts of unusual situations are properly  attributable
                  solely  to one  Class  and  therefore  should be borne by that
                  Class.  These expenses ("Special  Expenses") may include,  for
                  example: (i) the costs of preparing a proxy statement for, and
                  holding, a special meeting of shareholders to vote on a matter
                  affecting only one Class;  (ii) the costs of holding a special
                  meeting of  Directors  to  consider  such a matter;  (iii) the
                  costs of preparing a special  report  relating  exclusively to
                  shareholders  of one Class;  and (iv) the costs of  litigation
                  affecting  one  Class  exclusively.  J.  & W.  Seligman  & Co.
                  Incorporated   (the   "Manager")   shall  be  responsible  for
                  identifying expenses that are potential Special Expenses.

            iii.  Subject to clause iv. below, any Special Expense identified by
                  the Manager shall be treated as a Class Level Expense.

            iv.   Any Special Expense identified by the Manager that is material
                  to the  Class in  respect  of which  it is  incurred  shall be
                  submitted by the Manager to the Directors of the relevant Fund
                  on a case by case basis with a  recommendation  by the Manager
                  as to whether it should be treated as a Class  Level  Expense.
                  If approved by the  Directors,  such Special  Expense shall be
                  treated as a Class Level Expense of the affected class.

      C.    i.    Realized and unrealized  capital gains and losses  of  a  Fund
                  shall be  allocated to each class of that Fund on the basis of
                  the  aggregate  net  asset  value  of all  outstanding  shares
                  ("Record  Shares") of the Class in  relation to the  aggregate
                  net asset value of Record Shares of the Fund.

                                      -2-
<PAGE>


            ii.   Income  and  expenses  of a Fund  not  charged  directly  to a
                  particular Class shall be allocated to each Class of that Fund
                  on the following basis:

                  a.    For  periodic  dividend  funds,  on  the  basis  of  the
                        aggregate net asset value of Record Shares of each Class
                        in relation to the  aggregate  net asset value of Record
                        Shares of the Fund.

                  b.    For daily dividend  funds, on the basis of the aggregate
                        net  asset  value of  Settled  Shares  of each  Class in
                        relation  to the  aggregate  net asset  value of Settled
                        Shares of the Fund. "Settled Shares" means Record Shares
                        minus the  number  of shares of that  Class or Fund that
                        have been  issued but for which  payment has not cleared
                        and plus the  number  of  shares  of that  Class or Fund
                        which have been  redeemed but for which  payment has not
                        yet been issued.

      D.    On an ongoing  basis,  the  Directors,  pursuant to their  fiduciary
            responsibilities under the Act and otherwise, will monitor each Fund
            for the existence of any material  conflicts  among the interests of
            its  several  Classes.  The  Directors,  including a majority of the
            Disinterested  Directors,  shall take such  action as is  reasonably
            necessary  to eliminate  any such  conflicts  that may develop.  The
            Manager and Seligman Financial  Services,  Inc. (the  "Distributor")
            will  be  responsible   for  reporting  any  potential  or  existing
            conflicts to the Directors.  If a conflict  arises,  the Manager and
            the  Distributor  will be  responsible  at  their  own  expense  for
            remedying  such  conflict by  appropriate  steps up to and including
            separating the classes in conflict by  establishing a new registered
            management company to operate one of the classes.

      E.    The plan of each Fund  adopted  pursuant to Rule 12b-1 under the Act
            (the "Rule 12b-1 Plan")  provides  that the  Directors  will receive
            quarterly and annual statements  complying with paragraph (b)(3)(ii)
            of Rule 12b-1, as it may be amended from time to time. To the extent
            that  the  Rule  12b-1  Plan in  respect  of a  specific  Class is a
            reimbursement  plan, then only  distribution  expenditures  properly
            attributable to the sale of shares of that Class will be used in the
            statements to support the Rule 12b-1 fee charged to  shareholders of
            such Class. In such cases  expenditures not related to the sale of a
            specific  Class will not be  presented  to the  Directors to support
            Rule  12b-1  fees  charged  to  shareholders  of  such  Class.   The
            statements,  including  the  allocations  upon which they are based,
            will be subject to the review of the Disinterested Directors.

      F.    Dividends  paid by a Fund with respect to each Class,  to the extent
            any  dividends are paid,  will be calculated in the same manner,  at
            the same  time  and on the same day and will be in the same  amount,
            except that fee payments  made under the Rule 12b-1 Plan relating to
            the Classes will be borne  exclusively by each Class and except that
            any Class Level Expenses shall be borne by the applicable Class.

      G.    The Directors of each Fund hereby  instruct such Fund's  independent
            auditors to review  expense  allocations  each year as part of their
            regular  audit  process,  to inform the Directors and the Manager of
            any  irregularities  detected and, if specifically  requested by the
            Directors,  to prepare a written report thereon. In addition, if any
            Special  Expense is incurred by a Fund and is  classified as a Class
            Level Expense in the manner  contemplated by paragraph B. above, the
            independent  auditors for such Fund,  in addition to reviewing  such
            allocation,  are hereby  instructed  to report  thereon to the Audit
            Committee of the relevant Fund and to the Manager.  The Manager will
            be responsible  for taking such steps as are necessary to remedy any
            irregularities so detected, and will do so at its own expense to the
            extent such irregularities  should reasonably have been detected and
            prevented by the Manager in the  performance  of its services to the
            Fund.
