       The Municipal  Fund's National  Municipal  Series seeks to provide to its
shareholders  maximum  income  exempt from regular  federal  income taxes to the
extent consistent with preservation of capital and with  consideration  given to
opportunities  for capital gain by investing in investment  grade securities the
interest on which is exempt from regular  federal  income taxes.  The investment
objective of each of the  individual  Municipal Fund State Series is to maximize
income exempt from regular  federal income taxes and from personal  income taxes
in  that  state,   consistent   with  the   preservation  of  capital  and  with
consideration given to opportunities for capital gain by investing in investment
grade municipal securities of the designated state, its political  subdivisions,
municipalities and public authorities.

       The Municipal  Trust State Series,  except for the  California  Municipal
High-Yield  Series,  each seek high income  exempt from regular  federal  income
taxes and from  personal  income  taxes in their  respective  state  (other than
Florida  which  does not  impose  an  individual  income  tax)  consistent  with
preservation  of  capital  and with  consideration  given to  capital  gain,  by
investing in municipal  securities rated in the four highest rating  categories,
except that the  California  Municipal  Quality  Series  pursues its  investment
objective by investing only in municipal  securities  rated in the three highest
rating categories of Moody's Investors Service, Inc. ("Moody's") or  Standard  &
Poor's Corporation ("S&P").

       The California  Municipal  High-Yield  Series seeks the maximum amount of
income exempt from regular  federal income taxes and California  personal income
taxes consistent with  preservation of capital and with  consideration  given to
capital gain by investing primarily in California  municipal securities that are
rated in the medium and lower rating  categories  of Moody's or S&P or which are
unrated. The Series may invest up to 100% of its portfolio in lower rated bonds,
commonly known as "junk bonds." Such securities generally offer a higher current
yield than those in the higher rating  categories but also involve greater price
volatility and risk of loss of principal and income.  The  California  Municipal
High-Yield  Series  invests  primarily in high-yield,  high risk  securities and
therefore  may not be suitable for all  investors.  Investors  should  carefully
assess the risks  associated with an investment in this Series.  See "Investment
Objectives and  Policies--Seligman  California  Municipal High-Yield Series," in
this Prospectus.

   
       The New Jersey Fund seeks to maximize  income exempt from regular federal
income tax and New Jersey personal  income tax consistent  with  preservation of
capital  and with  consideration  given to  opportunities  for  capital  gain by
investing in  "investment  grade" New Jersey  municipal  securities.  Investment
grade  securities  are  rated  within  the four  highest  rating  categories  of
"Moody's" or "S&P." Throughout this Prospectus,  the New Jersey gross income tax
is referred to as the New Jersey personal income tax.
    

     The  Pennsylvania  Fund seeks to provide a high level of income exempt from
regular federal and Pennsylvania  income taxes  consistent with  preservation of
capital by  investing  primarily  in  investment  grade  Pennsylvania  municipal
securities.  Capital  appreciation  is not a  consideration  in the selection of
investments.  The Fund may also invest in Pennsylvania municipal securities that
are  unrated  but are  believed  by the  Manager  (as  defined  below)  to be of
comparable quality to investment grade securities.

       There can be no assurance that a Series will achieve its objective.

       Investment  advisory and management services are provided to the Funds by
J. & W. Seligman & Co.  Incorporated (the "Manager") and each Fund's distributor
is Seligman Financial Services,  Inc., an affiliate of the Manager.  Each Series
offers  two  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 eighteen months 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.

                           SUMMARY OF SERIES EXPENSES

   
       The purpose of this table is to assist  investors  in  understanding  the
various  costs and  expenses  which  shareholders  of a 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.  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 CDSL,
a one-time  charge,  only if the shares are redeemed  within  eighteen months of
purchase.  The CDSL on Class D shares is a one-time  charge  paid only if shares
are  redeemed  within  one year of  purchase.  For more  information  concerning
reduction in sales loads and for more complete descriptions of the various costs
and expenses see "Purchase of Shares,"  "Redemption  of Shares" and  "Management
Services"  herein.  Each  Fund's   Administration,   Shareholder   Services  and
Distribution  Plan, to which the caption "12b-1 Fees" relates is discussed under
"Administration, Shareholder Services and Distribution Plans" herein.

     of  .25 of 1%.  Pursuant  to the  rules  of  the  National  Association  of
     Securities  Dealers,  Inc.,  the aggregate  deferred sales loads and annual
     distribution  fees on Class D shares of each 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 D shareholder of a 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 one year,
     the expenses on a $1,000 investment would be: NAT'L--$18; CO--$18; GA--$18.

An investor would pay

assuming (1) 5% annual 
return and (2) redemption
at the end of each time period:

   * Includes an annual  distribution fee of .75 of 1% and an annual service fee
     of  .25 of 1%.  Pursuant  to the  rules  of  the  National  Association  of
     Securities  Dealers,  Inc.,  the aggregate  deferred sales loads and annual
     distribution  fees on Class D shares of each 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 D shareholder of a 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 one year,
     the expenses on a $1,000 investment would be: PA--$20.

                              FINANCIAL HIGHLIGHTS
   

       Each Series' financial  highlights for 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  Funds,  should  be read in  conjunction  with the  fiscal  1997
financial  statements  and notes  contained in the fiscal 1997 Annual  Report of
each Fund which may be obtained by calling or writing the Funds at the telephone
numbers or address provided on the cover page of this Prospectus.

       "Per share operating  performance" data is designed to allow investors to
trace the operating  performance,  on a per share basis,  from the beginning net
asset value to the ending net asset value so that they can understand the effect
that individual items have on their investment,  assuming it was held throughout
the period.  Generally,  the per share  amounts are  derived by  converting  the
actual  dollar  amounts  incurred for each item,  as disclosed in the  financial
statements, to their equivalent per share amounts.

       "Total  return based on net asset value"  measures a Series'  performance
assuming  investors  purchased shares 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 net  asset  value per share on the last day of the
period. The total return computations do not reflect any sales charges investors
may incur in  purchasing  or selling  shares.  Total returns for periods of less
than one year are not annualized.

ALTERNATIVE DISTRIBUTION SYSTEM

    Each  Series  offers  two  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  charges.  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
charges,  as  discussed  below,  or to have the entire  initial  purchase  price
invested  in a Series with the  investment  thereafter  being  subject to higher
ongoing charges and, for a one-year period, a CDSL.

    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 fee of 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 a Series  will be reduced by the
initial  sales load  deducted at the time of purchase.  Furthermore,  the higher
distribution  fees on 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 sales load deducted at the time of purchase would be less or waived in full.
However,  investors  should consider the effect of the 1% CDSL imposed on shares
on which the initial sales load was waived in full because the amount of Class A
shares purchased reached $1,000,000 or more.
    

    Alternatively,  some  investors  might  choose  to have all of  their  funds
invested initially by purchasing Class D shares, although remaining subject to a
higher  continuing  distribution  fee  and,  for a  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 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 D shares' 1%  distribution  fee,
fluctuations  in net asset  value or the effect of the return on the  investment
over this period of time.

    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 load and higher  distribution
fees with  respect  to Class D shares in that the sales  loads and  distribution
fees applicable to a Class provide for the financing of the  distribution of the
shares of the Series.

    The two  classes  of  shares  of a Series  represent  interests  in the same
portfolio of  investments,  have the same rights and are generally  identical in
all  respects  except  that each  class  bears its  separate  distribution  and,
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 applicable state
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  fee of each
class.  Class D shares bear higher  distribution  expenses  which will cause the
Class D shares to pay lower  dividends than the Class A shares.  The two classes
also have separate exchange privileges.

    The  Directors or Trustees of each Fund believe that no conflict of interest
currently  exists  between the Class A and Class D shares of each Series.  On an
ongoing basis,  they, in the exercise of their  fiduciary  duties under the 1940
Act and applicable  state law, will seek to ensure that no such conflict arises.
For this purpose,  they will monitor the Funds 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 and
Class D shares are their sales load structures and ongoing expenses as set forth
below. Each class has advantages and disadvantages for different investors,  and
investors should choose the class that best suits their  circumstances and their
objectives.

INVESTMENT OBJECTIVES AND POLICIES

MUNICIPAL SECURITIES

    As used in this  Prospectus,  "municipal  securities"  refers to  short-term
notes,  commercial  paper and  intermediate  and long-term bonds issued by or on
behalf of states,  territories  and  possessions  of the  United  States and the
District  of  Columbia,  and their  political  subdivisions  (such as  counties,
cities, boroughs,  townships,  school districts and authorities),  agencies, and
instrumentalities,  the  interest  on which is, in the opinion of counsel to the
issuers,  exempt from regular  federal  income taxes and, in certain  instances,
applicable state or local income taxes. Such interest may,  however,  be subject
to the federal  alternative minimum tax. Such securities are traded primarily in
the over-the-counter market.

    Municipal  bonds are issued to obtain  funds for  various  public  purposes,
including  the  construction  of a wide  range  of  public  facilities  such  as
airports, bridges, highways,  housing, hospitals, mass transportation,  schools,
streets, water and sewer works, and gas and electric utilities.  Municipal bonds
also may be issued in connection with the refunding of outstanding  obligations,
obtaining funds to lend to other public  institutions and for general  operating
expenses.

    The two principal classifications of municipal bonds are "general obligation
bonds" and "revenue bonds." General obligation bonds are secured by the issuer's
pledge of its faith,  credit and taxing power for the payment of  principal  and
interest.  Revenue bonds are payable from the revenues derived from a particular
facility  or class of  facilities  or, in some  cases,  from the  proceeds  of a
special excise tax or other specific  revenue  source,  but not from the general
taxing power.  In addition,  certain  types of  "industrial  development  bonds"
issued   by  or  on  behalf  of   public   authorities   to  obtain   funds  for
privately-operated  facilities  are eligible  for  purchase,  provided  that the
interest paid thereon qualifies as exempt from regular federal income taxes and,
in certain instances, applicable state and/or local taxes. Tax-exempt industrial
development bonds do not generally carry the pledge of the credit of the issuing
municipality.  Interest  earned from  certain  municipal  securities  (including
certain  industrial  development  bonds) that are  private  activity  bonds,  as
defined in the  Internal  Revenue  Code of 1986,  as amended  (the  "Code"),  is
treated as a preference item for purposes of the  alternative  minimum tax. Each
Series may invest any portion of its assets in municipal securities the interest
on which is subject to the alternative minimum tax. Under normal  circumstances,
each Series will invest at least 80% of its net assets in  municipal  securities
the interest on which is exempt from regular  federal  income tax (although such
interest  may be subject to the federal  alternative  minimum  tax) and state or
local income tax.

    Municipal notes generally are issued to provide for short-term capital needs
and generally have  maturities of 5 years or less.  They include such securities
as Tax Anticipation Notes,  Revenue  Anticipation Notes, Bond Anticipation Notes
and  Construction  Loan  Notes.

                                       21

<PAGE>

Municipal   commercial  paper  are  short-term  obligations  generally  having a
maturity of less than nine months.

    It should be noted that municipal  securities  may be adversely  affected by
local  political and economic  conditions and  developments  within a particular
state. For example, adverse conditions in an industry that is significant to the
state could have a correspondingly adverse effect on specific issuers within the
state or on anticipated revenue of the issuing state;  conversely,  an improving
economic  outlook for a significant  industry may have a positive effect on such
issuers or revenue.  The value of municipal securities is dependent on a variety
of factors,  including general  conditions in the money markets or the municipal
bond markets,  political and economic factors  nationally or within a state, the
size of the particular offering,  the supply of municipal bonds, the maturity of
the  obligation,  the credit  quality and rating of the issue and the assistance
provided to the bond issuing  authority by the  applicable  state.  Under normal
market conditions,  if general market interest rates are increasing,  the prices
of bonds will decrease.  In a market of decreasing  interest rates, the opposite
will generally be true. In either case, the longer the maturity, the greater the
effect.  A more detailed  description of the municipal  securities in which each
Series may  invest and  special  factors  relating  to them is set forth in each
Series' Statement of Additional Information.

SELIGMAN MUNICIPAL FUND SERIES, INC.

    The Municipal  Fund is a  non-diversified,  open-end  management  investment
company, as defined in the 1940 Act, incorporated in Maryland on August 8, 1983.
The  Municipal  Fund consists of a National  Series and twelve state Series,  as
described  below.  The  Municipal  Fund State  Series offer  investments  in the
following states:

             Colorado                     Minnesota
             Georgia                      Missouri
             Louisiana                    New York
             Maryland                     Ohio
             Massachusetts                Oregon
             Michigan                     South Carolina

    NATIONAL  SERIES seeks to maximize income exempt from regular federal income
taxes  to  the  extent   consistent  with   preservation  of  capital  and  with
consideration  given to  opportunities  for capital  gain.  Under normal  market
conditions,  the National  Series  attempts to invest  100%,  and as a matter of
fundamental  policy  will invest at least 80%, of the value of its net assets in
securities of states,  territories  and possessions of the United States and the
District  of  Columbia,   and  their   political   subdivisions,   agencies  and
instrumentalities,  the interest on which is exempt from regular  federal income
taxes. Such interest, however, may be subject to the federal alternative minimum
tax. There can be no assurance that the National Series will be able to meet its
investment objective.

    MUNICIPAL FUND STATE SERIES each seek to maximize income exempt from regular
federal income taxes and from the personal income taxes of its designated  state
to the extent  consistent with  preservation  of capital and with  consideration
given to  opportunities  for capital  gain.  Each  Municipal  Fund State  Series
attempts to invest 100%, and as a matter of fundamental  policy invests at least
80%,  of the value of its net  assets in  securities  the  interest  on which is
exempt from regular  federal income taxes and from the personal  income taxes of
the  designated  state.  Such interest,  however,  may be subject to the federal
alternative  minimum tax.  Each  Municipal  Fund State Series may also invest in
municipal  securities of issuers outside its designated state if such securities
bear  interest  that is exempt from  regular  federal  income taxes and personal
income taxes of the state. If, in abnormal market conditions, in the judgment of
the Manager,  municipal securities satisfying the investment objective of any of
the  Municipal  Fund  State  Series  are not  available  or for other  defensive
purposes,  such Municipal Fund State Series may temporarily  invest up to 20% of
the value of its net assets in instruments  the interest on which is exempt from
regular  federal  income  taxes,  but not  State  personal  income  taxes.  Such
securities  would include those set forth under  "Municipal  Securities"  above,
that would otherwise meet the Series' objective.  There can be no assurance that
a Municipal Fund State Series will be able to meet its investment objective.

                                       22
<PAGE>

    Each  Municipal  Fund State Series and the  National  Series are expected to
invest principally, without percentage limitations, in municipal securities that
are rated  investment  grade on the date of  investment.  Each  Series  also may
invest in unrated  municipal  securities  if, based upon credit  analysis by the
Manager,  it is  believed  that such  securities  are of  comparable  quality to
investment grade securities.

   
    In unusual  circumstances,  the  Municipal  Fund may invest up to 20% of the
value of its net assets on a temporary  basis in  fixed-income  securities,  the
interest on which is subject to federal,  state or local income tax, pending the
investment  or  reinvestment  in  municipal  securities  of proceeds of sales of
shares or sales of portfolio  securities  or in order to avoid the  necessity of
liquidating  portfolio investments to meet redemptions of shares by investors or
where market  conditions due to rising  interest rates or other adverse  factors
warrant  temporary  investing for  defensive  purposes.  Investments  in taxable
securities will be substantially in securities  issued or guaranteed by the U.S.
Government (such as bills, notes and bonds), its agencies,  instrumentalities or
authorities;  highly-rated  corporate debt securities  (rated AA-, or better, by
S&P or Aa3, or better,  by Moody's);  prime  commercial paper (rated A-1+/A-1 by
S&P or P-1 by  Moody's)  and  certificates  of  deposit of  "Acceptable  Banking
Institutions."  Acceptable  Banking  Institutions are defined as the 100 largest
(based on assets) banks that are subject to regulatory  supervision  by the U.S.
Government or state  governments  and the 50 largest  (based on assets)  foreign
banks  with  branches  or  agencies  in  the  United   States.   Investments  in
certificates of deposit of foreign banks and foreign  branches of U.S. banks may
involve  certain  risks,  including  different  regulation,   use  of  different
accounting  procedures,  political  or  other  economic  developments,  exchange
controls, or possible seizure or nationalization of foreign deposits.
    

SELIGMAN MUNICIPAL SERIES TRUST

    The Municipal  Trust is a  non-diversified  open-end  management  investment
company,  organized  as an  unincorporated  business  trust  under  the  laws of
Massachusetts  on July 27, 1984. The Municipal  Trust consists of Seligman North
Carolina   Municipal  Series,   Seligman  Florida  Municipal  Series,   Seligman
California Municipal Quality Series and Seligman California Municipal High-Yield
Series.

    SELIGMAN NORTH CAROLINA  MUNICIPAL SERIES (the "North Carolina  Series") and
SELIGMAN FLORIDA  MUNICIPAL SERIES (the "Florida  Series") each seek high income
exempt from regular federal income taxes (and with respect to the North Carolina
Series,  North Carolina  personal income taxes)  consistent with preservation of
capital  and with  consideration  given to capital  gain by  investing  in North
Carolina or Florida municipal  securities,  as applicable,  and investment grade
commercial paper rated within the two highest rating categories,  on the date of
investment.  Each Series  also may invest in unrated  municipal  securities  if,
based upon  credit  analysis by the  Manager  and under the  supervision  of the
Trustees,  it is believed  that such  securities  are of  comparable  quality to
investment  grade  securities.  There can be no assurance  that a Series will be
able to meet its investment objective.

    Each  Series will  attempt to invest  100%,  and as a matter of  fundamental
policy  will  invest  at least  80%,  of the  value of its net  assets  in North
Carolina or Florida municipal securities,  as applicable,  the interest on which
is exempt from regular federal taxes and, if applicable, North Carolina personal
taxes. Such interest, however, may be subject to the federal alternative minimum
tax. In abnormal  market  conditions  if, in the judgment of the Manager,  North
Carolina or Florida municipal  securities  satisfying such Series' objective may
not be  purchased,  the  Municipal  Trust  may  make  temporary  investments  in
securities  issued by states  other than North  Carolina or  Florida.  Moreover,
under such  conditions and for defensive  purposes,  a Series may make temporary
investments in high-quality securities, the interest on which is not exempt from
federal income tax or, if applicable, North Carolina personal taxes. Investments
in taxable  securities will be substantially in securities  issued or guaranteed
by the  U.S.  Government  (such  as  bills,  notes  and  bonds),  its  agencies,
instrumentalities or authorities;  highly-rated corporate debt securities (rated
AA-, or better,  by S&P or Aa3, or bet-

                                       23

ter,  by  Moody's);  prime  commercial  paper  (rated  A-1+/A-1 by S&P or P-1 by
Moody's) and  certificates  of deposit of Acceptable  Banking  Institutions,  as
defined under "Seligman Municipal Fund Series, Inc." Investments in certificates
of deposit of foreign  banks and  foreign  branches  of U.S.  banks may  involve
certain risks, as described above.

    Each Series is permitted to purchase project notes and standby  commitments;
however,  neither  Series  has  any  present  intention  of  investing  in  such
securities.

    SELIGMAN  CALIFORNIA  MUNICIPAL  QUALITY  SERIES  (the  "California  Quality
Series") seeks high income exempt from regular federal income taxes and from the
personal income taxes of California  consistent with preservation of capital and
with  consideration  given to capital gain by investing in California  municipal
securities  that on the date of investment are within the three highest  ratings
of  Moody's  (Aaa,  Aa, A for  bonds;  MIG1,  MIG2,  MIG3,  for  notes;  P-1 for
commercial  paper) or S&P (AAA,  AA, A for bonds;  SP-1,  SP-2 for notes;  A-1+,
A-1/A-2 for commercial  paper). The Series also may invest in unrated California
municipal  securities  if,  based upon  credit  analysis by the  Manager,  it is
believed that such securities are of comparable  quality to the rated securities
in which the series may invest.  The securities  held by the California  Quality
Series  ordinarily will have  maturities in excess of one year.  There can be no
assurance that the California Quality Series will be able to meet its investment
objective.

    SELIGMAN CALIFORNIA MUNICIPAL HIGH-YIELD SERIES (the "California  High-Yield
Series") seeks the maximum  income exempt from regular  federal income taxes and
from the personal  income taxes of California  consistent  with  preservation of
capital and with consideration  given to capital gain by investing in California
municipal  securities that on the date of investment are rated within the medium
to lower rating categories of Moody's (Baa or lower for bonds; MIG3 or lower for
notes; P-2 or lower for commercial paper) or S&P (BBB or lower for bonds; A-2 or
lower for  commercial  paper).  The  Series  may  invest in  unrated  California
municipal  securities  if,  based upon  credit  analysis by the  Manager,  it is
believed that such  securities  are of comparable  quality to securities  with a
medium or low credit rating.  The securities held by the Series  ordinarily will
have maturities in excess of one year. There can be no assurance that the Series
will be able to meet its investment objective.

    The securities in which the California  High-Yield  Series invests generally
involve  greater  volatility  of price and risk of loss of principal  and income
than securities in higher rating categories. Shares of the California High-Yield
Series are  appropriate  only for those investors who can bear the risk inherent
in seeking the highest tax-exempt yields.
   
    During the fiscal year ended September 30, 1997 the weighted average ratings
of the California  municipal  long-term  securities held by the California High-
Yield Series were as follows:

                                                            PERCENTAGE OF TOTAL
                      S&P/MOODY'S RATINGS                       INVESTMENTS
                    -----------------------                --------------------
AAA/Aaa .......................................................     2%
AA/Aa .........................................................     9%
A/A ...........................................................    50%
BBB/Baa .......................................................    17%
BB/Ba .........................................................     --
B/B ...........................................................     --
CCC/Caa .......................................................     --
Unrated .......................................................    22%
    

    California municipal securities in the fourth rating category of Moody's and
S&P,   although  commonly  referred  to  as  investment  grade,  may  have  some
speculative characteristics that may affect the issuer's ability to pay interest
and repay  principal.  California  municipal  securities  rated below the fourth
category  are subject to greater risk of loss of  principal  and  interest  than
higher-rated securities,  as they are predominantly  speculative with respect to
the issuer's ability to pay interest and repay principal.  California  municipal
securities rated below BBB by S&P or Baa by Moody's are also more susceptible to
price  volatility  due to general  economic  conditions  and changes in interest
rates. Since municipal securities are purchased from and sold to dealers, prices
at which these securities are sold will be affected by the degree of interest of
dealers to bid for them.  In certain  markets,  dealers may be unwilling

                                       24

<PAGE>

to make bids for the  securities  of certain  issuers that the seller  considers
reasonable.   Furthermore,  because  the  net  asset  value  of  the  California
High-Yield  Series' shares  reflects the degree of willingness of dealers to bid
for California  municipal  securities,  the price of the  California  High-Yield
Series' shares may be subject to greater fluctuation.

    Moody's and S&P's  ratings are generally  accepted  measures of credit risk.
They are, however,  subject to certain  limitations.  The rating of an issuer is
based heavily on past  developments  and does not necessarily  reflect  probable
future  conditions.  Ratings also are not updated  continuously.  For a detailed
description  of  the  ratings,  see  Appendix  A to  the  Series'  Statement  of
Additional Information.

    The  Manager  attempts to minimize  the risks to the  California  High-Yield
Series inherent in the investment in lower-rated California municipal securities
through analysis of the particular issuer and security, trends in interest rates
and local and general economic conditions,  diversification and when appropriate
by investing a substantial portion of the Series' assets in California municipal
securities rated in the fourth rating category or higher.

    Each of the California  Quality Series and the California  High-Yield Series
will attempt to invest 100%, and as a matter of  fundamental  policy will invest
at least 80%, of the value of its net assets in securities the interest on which
is exempt from  regular  federal and  California  personal  income  taxes.  Such
interest,  however,  may be subject to the federal  alternative  minimum tax. In
abnormal  market  conditions  if,  in the  judgment  of the  Manager,  municipal
securities  satisfying a Series'  objective may not be  purchased,  a Series may
make  temporary  investments  in securities the interest on which is exempt only
from regular federal income tax, such as securities  issued by states other than
California.  Moreover,  under  such  conditions,  a Series  may  make  temporary
investments in high-quality  securities the interest on which is not exempt from
either  federal or  California  personal  income taxes.  Investments  in taxable
securities will be substantially in securities  issued or guaranteed by the U.S.
Government (such as bills, notes and bonds), its agencies,  instrumentalities or
authorities;  highly-rated  corporate debt securities  (rated AA-, or better, by
S&P or Aa3, or better,  by Moody's);  prime  commercial paper (rated A-1+/A-1 by
S&P or P-1 by  Moody's)  and  certificates  of  deposit  of  Acceptable  Banking
Institutions,  as defined above under  "Seligman  Municipal  Fund Series,  Inc."
Investments in certificates of deposit of foreign banks and foreign  branches of
U.S. banks may involve certain risks, as described above.

    Furthermore,  when economic or market  conditions  warrant,  the  California
High-Yield Series may assume a temporary defensive position and invest up to 25%
of the value of its net assets in California  municipal  securities rated within
the three highest rating  categories of Moody's or S&P. The securities which the
Series will hold under this  circumstance  may have  maturities of less than one
year.

    Each of the California  Quality Series and the California  High-Yield Series
may enter  into  stand-by  commitments.  Under a stand-by  commitment,  a Series
obligates a dealer to repurchase at the Series' option specified securities at a
specified price. The exercise of a stand-by commitment is subject to the ability
of the  dealer to make  payment  on  demand.  A Series  would  acquire  stand-by
commitments  solely  to  facilitate  portfolio  liquidity  and not  for  trading
purposes.  Prior to investing in stand-by commitments the Municipal Trust, if it
deems necessary  based upon the advice of counsel,  will apply to the Securities
and Exchange  Commission for an exemptive order relating to such commitments and
the  valuation  thereof.  There  can be no  assurance  that the  Securities  and
Exchange Commission will provide such authorization.

    The price which a Series would pay for  municipal  securities  with stand-by
commitments  generally  would be higher than the price which  otherwise would be
paid for the municipal securities alone. A Series will only purchase obligations
with stand-by commitments from sellers the Manager deems creditworthy.

    Stand-by  commitments with respect to portfolio  securities of a Series with
maturities of less than 60 days which are separate from the underlying portfolio
securities are not assigned a value. The cost of any such

                                       25

<PAGE>

stand-by  commitment is carried as an unrealized  loss from the time of purchase
until it is exercised or expires. Stand-by commitments with respect to portfolio
securities  of a Series with  maturities  of 60 days or more which are  separate
from the underlying portfolio securities and the underlying portfolio securities
are valued at fair value as determined in accordance with procedures established
by the Board of Trustees.  The Board of Trustees  would,  in connection with the
determination of the value of such a stand-by  commitment,  consider among other
factors  the  creditworthiness  of the writer of the  stand-by  commitment,  the
duration of the stand-by  commitment,  the dates on which or the periods  during
which the stand-by  commitment  may be exercised  and the  applicable  rules and

    The  New  Jersey  Fund is a non-diversified, open-end  management investment
company, as defined in the 1940 Act, or mutual fund, incorporated in Maryland on
March 13, 1987.

    The New Jersey Fund seeks to maximize  income  exempt from  regular  federal
income tax and New Jersey personal  income tax consistent  with  preservation of
capital  and with  consideration  given to  opportunities  for  capital  gain by
investing in New Jersey municipal  securities that are rated investment grade on
the date of  investment.  The New  Jersey  Fund also may  invest  in New  Jersey
municipal  securities that,  while not rated as investment  grade, are not rated
lower than B by S&P or Moody's, or if not rated, are believed, based upon credit
analysis  by the  Manager,  to  have  at  least  comparable  credit  to B  rated
securities.  There can be no assurance  that the New Jersey Fund will be able to
meet its investment objective.

    The New  Jersey  Fund  will  attempt  to  invest  100%,  and as a matter  of
fundamental  policy, will invest at least 80%, of the value of its net assets in
securities  the interest on which is exempt from regular  federal income tax and
New Jersey  personal income tax. Such interest may,  however,  be subject to the
federal  alternative  minimum  tax. In  abnormal  market  conditions  if, in the
judgment of the Manager,  municipal securities  satisfying the New Jersey Fund's
objective may not be purchased or for other temporary  defensive  purposes,  the
New Jersey Fund may make  investments  in  securities  the  interest on which is
exempt only from regular federal income tax, such as securities issued by states
other than New Jersey,  or is exempt only from New Jersey  personal  income tax,
such as securities issued by the U.S.  Government (such as Treasury bills, notes
and bonds), its agencies, instrumentalities or authorities. Moreover, under such
conditions,  the  New  Jersey  Fund  may  also  make  temporary  investments  in
fixed-income  securities the interest on which is not exempt from either federal
income  tax  or New  Jersey  personal  income  tax.  Such  investments  will  be
substantially in highly-rated  corporate debt securities  (rated AA-, or better,
by S&P or Aa3, or better, by Moody's), prime commercial paper (rated A-1+/A-1 by
S&P or P-1 by  Moody's),  and  certificates  of  deposit of  Acceptable  Banking
Institutions as defined under "Seligman Municipal Fund Series, Inc." Investments
in certificates  of deposit of foreign banks and foreign  branches of U.S. banks
may involve certain risks, as described above.

    The New Jersey Fund is  permitted to  purchase  project  notes  and  standby
commitments;  however, the New Jersey Fund has no present intention of investing
in such securities.

SELIGMAN PENNSYLVANIA MUNICIPAL FUND SERIES

    The Pennsylvania Fund is a non-diversified,  open-end management  investment
company organized as an unincorporated  trust under the laws of the Commonwealth
of Pennsylvania by a Declaration of Trust dated May 13, 1986.

    The  Pennsylvania  Fund seeks high income exempt from regular federal income
tax and  Pennsylvania  income taxes  consistent with  preservation of capital by
investing in Pennsylvania  municipal  securities that are rated investment grade
on the date of  investment.  The  Pennsylvania  Fund also may  invest in unrated
Pennsylvania municipal securities if, based upon credit analysis by the Manager,
it is believed  that such  securities  are of  comparable  quality to investment
grade  securities.   The  securities  which  the  Pennsylvania  Fund  will  hold
ordinarily will have maturities in excess of one year. There can be no assurance
that the Fund will be able to meet its investment objective.

                                       26

<PAGE>

    The  Pennsylvania  Fund  will  attempt  to invest  100%,  and as a matter of
fundamental  policy  will invest at least 80%, of the value of its net assets in
securities the interest on which is exempt from regular federal and Pennsylvania
income taxes. Such interest,  however, may be subject to the federal alternative
minimum tax. In abnormal  market  conditions if, in the judgment of the Manager,
municipal  securities  satisfying the Pennsylvania  Fund's objectives can not be
purchased,  the Pennsylvania  Fund may make temporary  investments in securities
the interest on which is exempt only from regular  federal  income tax,  such as
securities  issued by states  other than  Pennsylvania,  or is exempt  only from
Pennsylvania  income tax, such as securities issued by the U.S. Government (such
as bills,  notes and bonds),  its agencies,  instrumentalities  or  authorities.
Moreover,  under  such  conditions,  the  Pennsylvania  Fund may make  temporary
investments in fixed-income  securities the interest on which is not exempt from
either  federal  or  Pennsylvania   income  taxes.   Such  investments  will  be
substantially in highly-rated  corporate debt securities  (rated AA-, or better,
by S&P or Aa3, or better, by Moody's), prime commercial paper (rated A-1+/A-1 by
S&P or P-1 by  Moody's)  and  certificates  of  deposit  of  Acceptable  Banking
Institutions,   as  defined  under  "Seligman   Municipal  Fund  Series,   Inc."
Investments in certificates of deposit of foreign banks and foreign  branches of
U.S. banks may involve certain risks, as described above.

    Although the underlying  value and quality of particular  securities will be
considered  in  selecting   investments  for  the  Pennsylvania   Fund,  capital
appreciation  will not be a  factor.  However,  the  Pennsylvania  Fund may sell
securities held in its portfolio and, as a result, realize capital gain or loss,
in order to eliminate unsafe investments and investments not consistent with the
preservation  of the  capital  or tax  status of the  Pennsylvania  Fund;  honor
redemption  orders;  meet anticipated  redemption  requirements and negate gains
from discount purchases; reinvest the earnings from portfolio securities in like
securities; or defray normal administration expenses.

    The  Pennsylvania  Fund  is  authorized  to  purchase  standby  commitments;
however,  the  Pennsylvania  Fund has no present  intention of investing in such
securities.

GENERAL

    Each Fund, as a non-diversified  investment  company,  is not limited by the
1940  Act  as to the  proportion  of  its  assets  that  it  may  invest  in the
obligations  of a single  issuer.  However,  each  Series  will  comply with the
diversification  requirements of the Code, as amended, and has therefore adopted
an investment  restriction,  which may not be changed without  shareholder  vote
(except for the New Jersey Fund),  prohibiting  each Series from purchasing with
respect to 50% of the value of the respective  Series' total assets,  securities
of any  issuer if  immediately  thereafter  more than 5% of such  Series'  total
assets would be invested in the securities of any single issuer. Furthermore, as
a matter of policy,  with respect to 75% of each Series' assets,  the respective
Series may not purchase  any revenue  bonds if  thereafter  more than 5% of such
Series'  assets  would be invested  in revenue  bonds of a single  issuer.  This
policy is not  fundamental  and may be changed by the Directors or Trustees,  as
applicable,  without shareholder approval. In the view of the Manager, the above
restriction  and policy reduce the risk that might  otherwise be associated with
an investment in a non-diversified investment company.

    As a matter of policy,  the Directors or Trustees,  as applicable,  will not
change a  Series'  investment  objective  without  a vote of a  majority  of the
outstanding  voting  security of that  Series.  Under the 1940 Act, a "vote of a
majority of the outstanding voting securities" of a 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  shareholder's
meeting if more than 50% of the outstanding shares of the Series are represented
at the meeting in person or by proxy.

    A more detailed list of each Series' investment  policies,  including a list
of those restrictions or investment  activities that cannot be changed without a
vote of a majority of the outstanding  voting  securities of a Series appears in
the Series' Statement of Additional Information.

    Investment  grade bonds and notes are within the four highest  credit rating
categories,  and  investment  grade  commercial  paper is within the two highest
credit rating  categories,  of Moody's (Aaa, Aa, A, Baa for bonds;

                                       27

<PAGE>

MIG 1, MIG 2, MIG 3, MIG 4 for  notes;  P-1--P-2  for  commercial  paper) or S&P
(AAA, AA, A, BBB for bonds;  SP-1--SP-2 for notes;  A-1+, A-1/A-2 for commercial
paper).  Although bonds and notes rated in the fourth credit rating category are
commonly   referred   to  as   investment   grade  they  may  have   speculative
characteristics.  Such characteristics may under certain circumstances lead to a
greater degree of market  fluctuations  in the value of such  securities than do
higher rated municipal  securities of similar maturities.  A detailed discussion
of such  characteristics  and  circumstances  and their  effect upon each Series
appears  in  the  Statements  of  Additional   Information   under  the  heading
"Investment Objectives, Policies And Risks." A description of the credit ratings
is contained in Appendix A to the Statements of Additional Information.

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

    WHEN LSSUED SECURITIES.  Each Series may purchase municipal  securities on a
"when  issued"  basis,  which  means  that  delivery  of and  payment  for  such
securities  normally  take place  within 45 days  after the date of the  buyer's
purchase commitment. The payment obligation and the interest rate on when-issued
securities are each fixed at the time the purchase  commitment is made, although
no interest  accrues to a purchaser  prior to the  settlement of the purchase of
the  securities.  As a result the yields  obtained  and the market value on such
securities may be higher or lower on the date when the  instruments are actually
delivered to the buyer.  A Series will generally  purchase a municipal  security
sold on a when  issued  basis  with the  intention  of  actually  acquiring  the
securities  on the  settlement  date.  Any gain  realized  from any such sale of
securities will be subject to federal and state taxes.

    A separate account  consisting of cash or high-grade  liquid debt securities
equal to the amount of outstanding  purchase commitments is established with the
Funds' Custodian in connection with any purchase of when issued securities.  The
account is marked to market daily,  with  additional  cash or liquid  high-grade
debt securities added when necessary.  A Series meets its respective  obligation
to purchase  when-issued  securities  from  outstanding  cash balances,  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 greater or lesser value than the Series'
payment obligations).

   VARIABLE AND FLOATING RATE OBLIGATIONS. The interest rates payable on certain
securities  in which a Series may invest are not fixed and may  fluctuate  based
upon changes in market rates.  The interest rate on variable rate obligations is
adjusted at  predesignated  periods and on floating  rate  obligations  whenever
there is a change in the market rate of interest on which the  floating  rate is
based.

    The interest rate is set as a specific percentage of a designated base rate,
such as the  rate on a  Treasury  Bond  or  Bill  or the  prime  rate at a major
commercial bank. Such a bond generally provides that a Series can demand payment
of the bond upon  seven  days'  notice at an  amount  equal to par plus  accrued
interest,

                                       28

<PAGE>

which amount, in unusual circumstances,  may be more or less than the  amount  a
Series paid for the bond.

    The   maturity  of  floating  or  variable   rate   obligations   (including
participation  interests  therein)  is deemed to be the longer of (i) the notice
period required before a Series is entitled to receive payment of the obligation
upon demand or (ii) the period  remaining until the  obligation's  next interest
rate  adjustment.  If not redeemed by a Series through the demand  feature,  the
obligations  mature on a specified  date which may range up to thirty years from
the date of issuance.

    PARTICIPATION INTERESTS. From time to time, a Series may purchase from banks
participation  interests  in all or  part  of  specific  holdings  of  municipal
securities.  Each  participation  interest is backed by an irrevocable letter of
credit  or  guarantee  of the  selling  bank.  Participation  interests  will be
purchased only if, in the opinion of counsel,  interest income on such interests
will be tax-exempt when distributed as dividends to shareholders of a Series.

    BORROWING.  Each  Series  may  borrow  money  only  from  banks and only for
temporary  or  emergency  purposes  (but  not  for  the  purchase  of  portfolio
securities)  in an amount not in excess of 10% of the value of its total  assets
at the time the borrowing is made (not including the amount borrowed). Permitted
borrowings  may be secured or unsecured.  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.

MANAGEMENT SERVICES

    THE MANAGER.  The Board of Directors or Trustees,  as  applicable,  provides
broad  supervision  over  the  affairs  of the  Funds.  Pursuant  to  Management
Agreements  approved by the Directors or Trustees and the  shareholders  of each
Series,  the  Manager  manages the  investment  of the assets of each Series and
administers  its business and other  affairs.  The address of the Manager is 100
Park Avenue, New York, NY 10017.

   
    In addition to serving the Funds,  the Manager serves as manager of fourteen
other investment companies which, together with the Funds, make up 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 High Income Fund
Series, Seligman Income Fund, Inc., Seligman Portfolios,  Inc., Seligman Quality
Municipal Fund, Inc.,  Seligman Select Municipal Fund, Inc., Seligman Value Fund
Series,  Inc.  and  Tri-Continental  Corporation.  The  aggregate  assets of the
Seligman  Group were  approximately  $18.0  billion at December  31,  1997.  The
Manager also provides investment management or advice to institutional and other
accounts having a December 31, 1997 value of approximately $6.3 billion.
    

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

    The Manager also  provides  senior  management  for Seligman  Data Corp.,  a
wholly owned subsidiary of certain  investment  companies in the Seligman Group,
which  performs,  at cost,  certain  recordkeep-ing  functions  for  each  Fund,
maintains the records of shareholder  investment  accounts and provides  related
services.

   
    The Manager is entitled to receive a management fee from each Series for its
services,  calculated  daily and payable  monthly,  equal to .50% of the average
daily net assets of each Series on an annual basis. The Manager has from time to
time  voluntarily  waived a portion of its management fee with respect to one or
more of the Series.  Each Fund pays all its expenses other than those assumed by
the Manager;  expenses are allocated  among the Series of the Municipal Fund and
of the Municipal Trust in a manner determined by the Directors or Trustees to be
fair and  equitable.  The  management  fee paid by each  Series  expressed  as a
percentage  of  average  daily net  assets of that  Series is  presented  in the
following table for the fiscal year ended September 30,1997.  Total expenses for
each Series'  Class A and D shares,  expressed as an  annualized  percentage  of
average daily net assets, are also presented in the following table for the year
ended September 30, 1997.

     PORTFOLIO MANAGEMENT.  Thomas G. Moles, Vice President and Senior Portfolio
Manager of each of the Funds,  is a Managing  Director of J. & W. Seligman & Co.
Incorporated,  as well as  President  and Senior  Portfolio  Manager of Seligman
Quality  Municipal  Fund,  Inc. and Seligman  Select  Municipal Fund, Inc. He is
responsible for more than $1.8 billion in municipal securities.  Mr. Moles, with
more  than  25  years  of  experience,   has  spearheaded  Seligman's  municipal
investment efforts since joining the Manager in 1983.

    The Manager's discussion of each Series' performance as well as a line graph
illustrating  comparative  performance information between each Series of a Fund
and the Lehman  Brothers  Municipal  Bond Index is  included  in the  respective
Fund's  fiscal 1997 Annual  Report to  shareholders.  Copies of a Fund's  Annual
Report may be obtained,  without charge,  by calling or writing the Funds 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.  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.  In
underwritten offerings, securities are purchased at a fixed price which includes
an amount of compensation to the underwriter.

    The  Management  Agreements  recognize  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 Manager for
its use in connection with its services to the Funds as well as other clients.

    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 Directors or Trustees may determine,  the Manager may
consider sales of shares of the Funds (and,  under applicable laws, of the other
Seligman  Mutual  Funds) as a factor in the  selection  of  dealers  to  execute
portfolio transactions for the Funds.

    PORTFOLIO  TURNOVER.  A change in securities  held by any Series is known as
"portfolio  turnover"  and may  involve  the  payment  by such  Series of dealer
spreads or underwriting  commissions and other transactions costs on the sale of
the  securities  as  well  as on the  reinvestment  of  the  proceeds  in  other
securities.  While  it is the  policy  of each  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 of
any Series is not expected to exceed 100%.

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.

    Each  Series  issues  two  classes  of  shares:  Class A shares  are sold to
investors  choosing the initial sales load  alternative;  and Class D shares are
sold to investors choosing no initial sales load, a higher  distribution

                                       30

<PAGE>

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  IS $1,000  FOR EACH  SERIES;
SUBSEQUENT  INVESTMENTS  MUST  BE IN THE  MINIMUM  AMOUNT  OF $100  (EXCEPT  FOR
INVESTMENT OF DIVIDENDS AND CAPITAL GAIN  DISTRIBUTIONS).  THE FUNDS RESERVE THE
RIGHT TO RETURN  INVESTMENTS  THAT DO NOT SATISFY THESE MINIMUMS.  EXCEPTIONS TO
THESE MINIMUMS ARE AVAILABLE FOR ACCOUNTS BEING  ESTABLISHED  CONCURRENTLY  WITH
THE INVEST-A-CHECK(R)  SERVICE. THE MINIMUM AMOUNT FOR INITIAL INVESTMENT IN THE
SELIGMAN  TIME  HORIZON  MATRIXSM  ASSET  ALLOCATION  PROGRAM  IS  $10,000.  FOR
INFORMATION ABOUT THIS PROGRAM, CONTACT YOUR FINANCIAL ADVISOR.

     The  minimum  amount  for  initial  investment  in each  Series is $500 for
investors  who purchase  shares of the Fund through  Merrill  Lynch's MFA or MFA
Select Programs.

     There is no minimum  investment  required for investors who purchase shares
of the Series through wrap fee programs.

     Orders received by an authorized  dealer by the close of regular trading on
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 regular  trading  on 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
regular  trading on the NYSE,  or received by SFSI after the close of  business,
will be executed at the Series'  net asset value next  determined  plus,  in the
case of Class A shares, any applicable sales load. The authorized dealer through
which the 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
payments,  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  (Name of Fund and
Series) (A 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 Funds  make no charge for this
service, the transmitting bank may impose a wire service fee.

   
    Current  shareholders may purchase additional shares of the Fund at any time
through any authorized  dealer or by sending a check payable to "Seligman  Group
of Funds" in our  postage-paid  return  envelope or  directly  to SELIGMAN  DATA
CORP., P.O. BOX 3947, NEW YORK, NY 10008-3947.  Checks for investment must be in
U.S.  dollars drawn on a domestic  bank.  The checks should be accompanied by an
investment slip (provided on the bottom of shareholder  account  statements) and
include the shareholder's name, address, account number, Fund or Series name and
class of  shares  (A 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.  IF ONLY THE CLASS DESIGNATION IS
MISSING,  THE INVESTMENT WILL  AUTOMATICALLY  BE MADE IN CLASS A SHARES.  Credit
card  convenience  checks and third party checks  (i.e.,  checks made payable to
someone other than the "Seligman  Group of Funds") may not be used to open a new
fund account or purchase  additional shares of the Fund. Orders sent directly to
Seligman  Data Corp.  will be executed  at the 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. may charge a $10.00  processing fee for checks  returned
to it as  uncollectable.  This  charge may be  deducted  from the  shareholder's
account.  For the protection of the Funds and their shareholders,  no redemption
proceeds will be remitted to a shareholder  with respect to shares  purchased by
check  (unless  certified)  until the Fund  receives  notice  that the check has
cleared,  which  may be up to 15 days  from the  credit  of such  shares  to the
shareholder's account.

    VALUATION.  The net asset value of a Series'  shares is determined as of the
close of regular trading on the NYSE (normally,  4:00 p.m.  Eastern time),  each
day,  Monday through Friday,  except on days that the NYSE is closed.  Net asset
value is calculated separately for each class of a Series.  Municipal securities
and  short-term  holdings  maturing  in more  than 60 days are  valued  based on
quotations provided by an independent pricing service, approved by the Directors
or  Trustees,  or in the  absence  thereof,  at  fair  value  as  determined  in
accordance  with  procedures  approved by the Directors or Trustees.  Short-term
holdings  maturing in 60 days or less are  generally  valued at amortized  cost.
Taxable  securities are valued at market value, or in the absence thereof,  fair
value as determined in accordance with  procedures  approved by the Directors or
Trustees.
    

    Although  the legal  rights of Class A 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 D shares  will
generally be lower than the net asset value of Class A shares as a result of the
higher distribution fee charged to Class D shares. In addition,  net asset value
per share of the two  classes  will be  effected  to the extent any other  class
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 Plans" below.

be subject to  a  CDSL  of  1% if  redeemed  within  18 months of purchase.  See
"Purchase of Shares--Contingent Deferred Sales Load."
    
- --------------------------------------------------------------------------------

    There is no initial  sales load on purchases of Class A shares of $1,000,000
or more ("NAV  sales");  however,  such shares are subject  to  a CDSL  of 1% if
redeemed within eighteen months of purchase.

    SFSI shall pay broker/dealers,  from its own resources,  a fee on NAV sales,
calculated  as follows;  1.00% NAV of sales up to but not  including $2 million;
 .80% of NAV sales from $2 million up to but not  including  $3 million;  .50% of
NAV sales from $3 million up to but not  including  $5 million;  and .25% of NAV
sales from $5 million  and above.  The  calculation  of the fee will be based on
assets held by a "single person" as defined below.

   
    SFSI shall also pay broker/dealers, from its own resources, a fee in respect
of certain  investments  in Class A shares of the  Seligman  Mutual  Funds by an
"eligible  employee  benefit plan" (as defined below under  "Special  Programs")
which are attributable to the particular broker/dealer.  The shares eligible for
the fee are those on which an initial  front-end 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
for each Plan during a single  calendar  year, or portion  thereof.  The payment
schedule,  for each  calendar  year is as follows:  1.00% of sales up to but not
including $2 million;  .80% of sales from $2 million up to but not  including $3
million;  .50% of sales from $3 million up to but not including $5 million;  and
 .25% of sales from $5 million and above.
    

    REDUCED SALES LOADS. Reductions in 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.

                                       32
<PAGE>

   
    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 a Series  alone,  or in any  combination  of  shares  of the  other
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 any Seligman  Mutual Fund sold with an initial  sales load
with the total  net asset  value of shares  sold  with an  initial  sales  load,
including  shares of  Seligman  Cash  Management  Fund that were  acquired by an
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 an investor must  indicate if 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 over a
13-month period at reduced initial sales loads,  based upon the total amount 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  by the  investor  through an  exchange of shares of another
Seligman  Mutual Fund on which there was an initial sales load. An investor or a
dealer  purchasing shares on behalf of an investor must indicate if 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."
    

    SPECIAL PROGRAMS.  Each 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  Funds,  the other  investment
companies in the Seligman Group, the Manager and other companies affiliated with
the 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 plans 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;  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  financial
institution trust  departments;  to registered  investment  advisers  exercising
investment  discretionary  authority  with  respect  to the  purchase  of Series
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 Series;  to other
investment  companies in the Seligman  Group in  connection  with a deferred fee
arrangement  for outside  directors;  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 a 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
ter-

                                       33


<PAGE>

minations at the plan level only, on redemptions  of  shares   purchased  within
eighteen months prior to plan  termination.  Sales pursuant to a 401(k) alliance
program  which has an agreement  with SFSI are  available at net asset value and
are not subject to a CDSL.

    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.

    CONTINGENT  DEFERRED  SALES LOAD. A CDSL will be imposed on  redemptions  of
Class D shares which were  purchased  during the preceding  twelve  months.  The
amount of any CDSL will  initially  be used by SFSI to defray the expense of the
payment  of  1%  made  by  it  to  Service   Organizations   (as  defined  under
"Administration,  Shareholder  Services and  Distribution  Plan") at the time of
sale.

    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 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.

   
    The 1% CDSL normally imposed on redemptions of certain Class A shares (i.e.,
those purchased during the preceding eighteen months at net asset value pursuant
to the sales load schedule provided under "Class A Shares--Initial  Sales Load")
will be waived on shares that were purchased through Dean Witter Reynolds,  Inc.
("Dean Witter") by certain Chilean institutional investors (i.e., pension plans,
insurance  companies and mutual funds). Upon redemption of such shares within an
eighteen-month period, Dean Witter will reimburse SFSI a pro rata portion of the
fee it received from SFSI at the time of sale of such shares.

    To minimize  the  application  of a CDSL to a  redemption,  shares  acquired
pursuant to the  investment of dividends and capital gain  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  CDSL 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. No CDSL will be imposed on shares  acquired  through the  investment of
dividends or distributions from any Class A or Class D shares of mutual funds in
the Seligman Group.
    

    For example,  assume an investor  purchased 100 shares in January at a price
of $10.00 per share.  During the first year, 5 additional  shares were  acquired
through investment of dividends and  distributions.  In January of the following
year, an additional 50 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 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
                                                                      ==========
  Dividend/Distribution shares
    (5 @ $12.25)                                                         $ 61.25
  Shares over 1 year old
    (100 @ $12.25)                                                      1,225.00
  Shares less than 1 year old subject to

                                                                      ----------

  Less CDSL (17.449 shares @ $12.00 =
    $209.39 x 1% = $2.09)                                                 (2.09)
                                                                      ----------

    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.
    

                                       34

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

   
    (a) on redemptions  following the death or disability (as defined in section
72(m)(7) of the Code) of a shareholder  or beneficial  owner;  (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
(an "IRA") due to death,  disability,  minimum  distribution  requirements after
attainment of age 701/2, or, for accounts  established prior to January 1, 1998,
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  Directors  or Trustees  of the Funds;  (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) in whole or in part, in connection with automatic cash withdrawals;
(f) in connection  with  participation  in the Merrill Lynch Small Market 401(k)
Program;  and (g) in connection with the redemption of shares of a Fund if it 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 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 Seligman  Mutual Funds.  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 a  registered  representative  who has sold or may sell a
significant amount of shares of a Fund and/or certain other mutual funds managed
by the Manager during a specified  period of time. Such bonus or other incentive
may take the form of payment for travel expenses, including lodging, incurred in
connection with trips taken by qualifying registered representatives and members
of their  families to places  within or outside the United  States.  The cost to
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,   has  the  ability  to  effect  the   following
transactions  via telephone:  (i) redemption of Series shares with proceeds sent
to address or record (up to $50,000 per day per fund account),  (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.

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

                                       35
<PAGE>

   
    FOR  CORPORATIONS  OR GROUP  RETIREMENT  PLANS:  Telephone  services are not
permitted.
    

    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 telephone services election form.

    For accounts registered jointly (such as joint tenancies,  tenants in common
and community  property  registrations),  each owner, by accepting or requesting
telephone  transaction  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 should consider using other redemption
or  exchange  procedures.  (See  "Redemption  of  Shares.")  Use of these  other
redemption or exchange procedures may result in the request being processed at a
later time than if a  telephone  transaction  had been used,  and a Series'  net
asset value may fluctuate during such periods.
    

    Each 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
each 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 a 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 a Fund or Seligman Data
Corp. does not follow the procedures described above, such 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  transaction  services.  Telephone  services  may be
terminated by a shareholder at any time by sending a written request to Seligman
Data Corp.  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  ("uncertificated") 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, NY 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 without charge,  except a CDSL, if applicable,  by surrendering
certificates  in proper form to the same  address.  Certificates  should be sent
certified or registered mail,  return receipt is advisable (may increase mailing
time).  Share  certificates  must be endorsed for transfer or  accompanied by an
endorsed  stock  power  signed  by all  shareowners  exactly  as  their  name(s)
appear(s) on the account  registration.  The shareholder's letter of instruction
or endorsed  stock  power  should  specify  the name of the Series,  the account
number,  class of  shares (A or D) and  number of shares or dollar  amount to be
redeemed.  The  Funds  cannot  accept  conditional  redemption  requests  (i.e.,
requests to sell shares at a specific price or on a future date).
    

                                       36

    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) or the New York
Stock Exchange  Medallion  Signature Program (MSP). A 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 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 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 may also "sell" shares to a 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 Funds make 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 regular trading on
the NYSE (normally 4:00 p.m.  Eastern Time) 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 at 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 a 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 fund account. Proceeds will
be sent to the  address of record.  Telephone  redemption  requests  received by
Seligman  Data Corp.  at (800)  221-2450 by the close of regular  trading on the
NYSE (normally 4:00 p.m. Eastern Time) will be processed at the Fund's net asset
value determined as of the close of business on that day. Redemption requests by
telephone will not be accepted within 30 days following an address change. IRAs,
group  retirement  plans,  corporations  and  trusts  for  which the name of the
current trustee does not appear in the account registration are not eligible for
telephone redemptions.  Each Fund reserves the right to suspend or terminate its
telephone redemption service at any time without notice.
    

    For more  information  about telephone  redemptions,  and the  circumstances
under which shareholders 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

                                       37

<PAGE>

   
shares in a Series  worth  $25,000 or more to  request  Seligman  Data Corp.  to
provide  redemption checks to be drawn on the account associated with the Series
in  which  the  shareholder  is  invested,  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.
Holder 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 Mellon Bank, N.A. rules and regulations  covering checking  accounts.
Separate checkbooks will be furnished for each Series.

    There  is no  charge  for use of  checks.  When  honoring  a check  that was
processed for payment,  Mellon Bank,  N.A. will cause a 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
will need to be signed by all persons,  unless otherwise elected under Section 6
of 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  in a Series to
cover the amount of checks written on that Series. If insufficient shares are in
the account, the check will be returned marked  "insufficient  funds." THE FUNDS
WILL NOT REDEEM SHARES OF 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 Seligman Data Corp. has  a certified  Tax
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 a Fund or Mellon Bank, N.A. See "Terms and Conditions."
    

    FOR THE  PROTECTION  OF THE FUNDS AND THEIR  SHAREHOLDERS,  NO PROCEEDS OF A
CHECK  REDEMPTION  WILL BE  REMITTED  TO A  SHAREHOLDER  WITH  RESPECT TO SHARES
PURCHASED BY CHECK (UNLESS  CERTIFIED)  UNTIL  SELIGMAN DATA CORP.  HAS RECEIVED
NOTICE THAT THE CHECK HAS CLEARED, WHICH MAY BE UP TO 15 DAYS FROM THE CREDIT OF
SUCH SHARES TO THE SHAREHOLDER'S ACCOUNT.

   
    GENERAL. With respect to shares redeemed, a check for the proceeds, less any
applicable  CDSL,  will be sent to the  shareholder's  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,  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.  Payment of redemption  proceeds will be
delayed on redemptions  of 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 such  shares to the  shareholder's  account.  No
interest is paid on the redemption  proceeds after the redemption but before the
funds are paid.  The proceeds of a redemption or repurchase  may be more or less
than the shareholder's cost.
    

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

                                       38

<PAGE>

   
redemption to reinstate,  free of an initial sales load,  all or any part of the
investment in Class A shares of the Series or any 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  applicable  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  accepted.  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
RE-DEEMED;  AND THE FUND'S MINIMUM INITIAL  INVESTMENT AMOUNT 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 a 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 PLANS

    Under each Fund's Administration, Shareholder Services and Distribution Plan
(the  "Plan"),  each  Series  may  pay to SFSI  an  administration,  shareholder
services and  distribution  fee in respect of each  Series'  Class A 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 a 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 each
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 SFSl's costs incurred in connection with
its marketing  efforts with respect to shares of a 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 each Series.

    Under its Plan, each 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 a Series' 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 a Series' 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 Directors or Trustees of
the Funds.

   
    The Plan, as it relates to Class A shares of the Municipal  Fund,  was first
approved  by the  Directors  on July 21,  1992 and by the  shareholders  of each
Series on November  23, 1992.  The Plan,  as it relates to the Class A shares of
the California  High-Yield Series and the California  Quality Series,  was first
approved by the  Trustees on July 21, 1992 and by the  shareholders  on November
23, 1992.  The Plan, as it relates to the Class A shares of the Florida  Series,
was first approved by the Trustees on June 21, 1990 and by the  shareholders  on
December  7,  1990.  The  Plan,  as it  relates  to Class A shares  of the North
Carolina Series,  was first approved by the Trustees on June 21, 1990 and by the
shareholders on April 11, 1991. The Plan, as it relates to the Class A shares of
the New Jersey Fund, was first approved by the Directors on January 12, 1988 and
by the shareholders on December 16, 1988. The Plan, as it relates to the Class A
shares of the Pennsylvania  Fund, was first approved by the Trustees on June 10,
1986 and by the  shareholders  on April 23, 1987. The total amounts paid for the
year ended September 30, 1997 in respect of each Series' Class A shares' average
daily net assets pursuant to the Plan were as follows:

    Under its Plan, each Series reimburses SFSI for its expenses with respect to
Class D shares  at an  annual  rate of up to 1% of the  average  daily net asset
value of the Class D shares.  Proceeds from a Series' Class D  distribution  fee
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 a Series'
Class D shares  attributable to particular  Service  Organizations for providing
personal  services  and/or the  maintenance  of  shareholder  accounts) and will
initially  be used by SFSI to defray the expense of the 1% payment to be made by
it to  Service  Organizations  at the time of the sale of  Class D  shares.  The
amounts  expended by SFSI in any one year upon the  initial  purchase of Class D
shares  may exceed  the  amounts  received  by it from Plan  payments  retained.
Expenses of administration,  shareholder  services and distribution of a Series'
Class D shares in one fiscal  year may be paid from a Series'  Class D Plan fees
received in any other fiscal year.  Each Plan,  as it relates to Class D shares,
was  approved by the  Directors  or  Trustees  on  November  18, 1993 and became
effective  February 1, 1994. The total amount paid for the year ended  September
30,  1997,  in respect of each Series'  Class D shares  pursuant to the Plan was
1.00% per annum of each Series' Class D shares'  average daily net assets.  Each
Plan is reviewed by the Directors or Trustees annually.

    Seligman Services,  Inc. ("SSI"),  an affiliate of the Manager, is a limited
purpose  broker/dealer.  SSI acts as  broker/dealer  of record  for  shareholder
accounts  that do not have a  designated  broker/dealer  of record and  receives
compensation  from a Series pursuant to its Plan for providing  personal service
and account maintenance to such accounts and other distribution services.

EXCHANGE PRIVILEGE

    A shareholder may,  without charge,  exchange at net asset value any part or
all of an investment  in a Series for shares of another  Series or for shares 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 and Class D shares may  be  exchanged  only for  Class A and Class D
shares,  respectively, of another  Seligman Mutual Fund 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 period for which the original shares were held.
    

    Aside from the Series  described in this  Prospectus,  the  Seligman  Mutual
Funds available under the Exchange Privilege are:

    O SELIGMAN CAPITAL FUND, INC. seeks aggressive capital appreciation. Current
income is not an objective.

    O SELIGMAN CASH MANAGEMENT  FUND, INC.  invests in high quality money market
instruments. Shares are sold at net asset value.

    O SELIGMAN  COMMON  STOCK FUND,  INC.  seeks  favorable  current  income and
long-term  growth of both

                                       40

<PAGE>

income and capital value without  exposing  capital to undue risk.

    O SELIGMAN  COMMUNICATIONS  AND INFORMATION  FUND, INC. invests in shares of
companies in the  communications,  information and related industries to produce
capital gain. Income is not an objective.

    O SELIGMAN  FRONTIER  FUND,  INC.  seeks to produce growth in capital value,
income may be considered  but will only be  incidental to the fund's  investment
objective.

    O SELIGMAN GROWTH FUND, INC. seeks  longer-term  growth in capital value and
an increase in future income.

    O SELIGMAN  HENDERSON  GLOBAL FUND  SERIES,  INC.  consists of the  Seligman
Henderson  Emerging  Markets Growth Fund, the Seligman  Henderson  Global Growth
Opportunities  Fund, the Seligman  Henderson Global Smaller  Companies Fund, the
Seligman   Henderson   Global   Technology  Fund  and  the  Seligman   Henderson
International  Fund all of which seek long-term capital  appreciation  primarily
through investing in companies either globally or internationally.

    O SELIGMAN HIGH INCOME FUND SERIES seeks high current income by investing in
debt securities.  The Fund consists of the Seligman U.S.  Government  Securities
Series and the Seligman High-Yield Bond Series.

    O SELIGMAN  INCOME FUND,  INC. seeks high current income and the possibility
of improvement of future income and capital value.

   
    O SELIGMAN VALUE FUND SERIES,  INC. consists of the Seligman Large-Cap Value
Fund and the  Seligman  Small-Cap  Value  Fund,  each of which  seeks  long-term
capital  appreciation  by  investing  in equity  securities  of value  companies
primarily located in the U.S.

    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  by the close of regular  trading on the NYSE
(normally, 4:00 p.m. Eastern Time) by Seligman Data Corp. at (800) 221-2450 will
be processed as of the close of business on that day.  Requests  received  after
the close of  regular  trading  on the NYSE will be  processed  at the net asset
value per share  calculated the following  business 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 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 AND
AUTOMATIC  CASH  WITHDRAWAL  SERVICE,  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 an exchange  request
together with certificates representing shares to be exchanged in proper form.
    

    The terms of the  exchange  offer  described  herein may be  modified at any
time;  and not all of the mutual  funds in the Seligman  Group are  available to
residents of all states.  Before  making any exchange,  contact your  authorized
investment  dealer or Seligman Data Corp. to obtain  prospectuses  of any of the
Seligman Mutual Funds.

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

                                       41

<PAGE>

der may be processed by mail.  For more  information  about  telephone  exchange
privileges,  which,  unless  objected to, are  assigned to certain  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
and state income tax purposes.

FURTHER INFORMATION ABOUT
TRANSACTIONS IN THE FUNDS

    Because excessive trading  (including  short-term,  "market timing" trading)
can hurt a Series'  performance,  a Fund, on behalf of a Series,  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.  A 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,  each Fund  reserves  the right to
refuse any order for the purchase of shares.

   
DIVIDENDS AND GAIN DISTRIBUTIONS
    

    Each Series  intends to declare  dividends of net  investment  income daily.
Dividends  are paid on the 17th day of each month.  If the 17th day of the month
falls on a weekend or holiday on which the NYSE is closed,  the dividend will be
distributed on the previous  business day.  Payments vary in amount depending on
income received from portfolio securities,  expenses of operation and the number
of days in the period.

    Shares will begin  earning  dividends on the day on which a Series  receives
payment and shares are issued.  Shares  continue to earn  dividends  through the
date preceding the date they are redeemed or delivered subsequent to repurchase.

    Each Series  distributes  substantially all of any taxable net long-term and
short-term  gain realized on  investments to  shareholders  at least annually in
accordance  with  requirements  under  the  Internal  Revenue  Code of 1986,  as
amended, and other applicable statutory and regulatory requirements.

   
    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  distributions  are reinvested in additional  shares.  Unless
another election is made,  dividends and 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 gain distribution.
    

    The per share  dividends  from net  investment  income on a Series'  Class D
shares will be lower than the per share dividends on a Series' Class A shares as
a result of the higher  distribution  fee  applicable  with respect to a Series'
Class D shares.  Per share  dividends  of the two  classes  may also differ as a
result of differing class expenses, if any.  Distributions of net capital gains,
if any, will be paid in the same amount for Class A and Class D shares.

                                       42
<PAGE>

   
    Shareholders  exchanging  shares for shares of another  Seligman Mutual Fund
will  continue to receive  dividends and gains as elected prior to such exchange
unless otherwise specified.  In the event that a shareholder  redeems 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.  A transfer or exchange of all shares  (closing an account),
between the record date and payable date,  will result in the value of dividends
or gain distributions  being paid to the new fund account in accordance with the
option  on  the  closed  account,  unless  Seligman  Data  Corp.  is  instructed
otherwise.
    

TAXES

FEDERAL INCOME TAXES

    Each Series intends to continue to qualify as a regulated investment company
under the Code. Thus qualified,  each Series will be relieved of regular federal
income tax on income  distributed to  shareholders  provided that it distributes
each year to its shareholders at least 90% of its net investment  income and net
short-term capital gains, if any.

    If, at the close of each quarter of its taxable  year,  at least 50% of each
Series'  total assets is invested in  obligations  exempt from  regular  federal
income tax the Series will be eligible to pay dividends  that are  excludable by
shareholders  from gross income for regular federal income tax purposes ("exempt
interest  dividends").  The total amount of exempt interest  dividends paid by a
Series to shareholders with respect to any taxable year cannot exceed the amount
of federally  tax-exempt  interest received by a Series during the year less any
expenses allocable to such interest.

   
    Distributions of net capital gain (i.e., the excess of net long-term capital
gains over net short-term  capital losses  ("capital gain  distributions"))  are
taxable to shareholders as long-term capital gain, whether received in shares or
cash, regardless of how long a shareholder has held shares in the Series, except
that the portion of net capital gains  representing  accrued market  discount on
tax-exempt obligations acquired after April 30, 1993 will be taxable as ordinary
income.  Individual  shareholders  will be  subject  to  federal  income  tax on
distributions  of net capital  gains at a maximum rate of 28% if  designated  as
derived from the Series' capital gains from property held for more than one year
and at a maximum rate of 20% if designated  as derived from the Series'  capital
gains from property held for more than  eighteen  months.  Net capital gain of a
corporate   shareholder   is  taxed  at  the  same  rate  as  ordinary   income.
Distributions from a Series' other investment income (other than exempt interest
dividends) or from net realized  short-term gain will be taxable to shareholders
as  ordinary  income,   whether  received  in  cash  or  in  additional  shares.
Distributions  will  not,  generally,  be  eligible  for the  dividends-received
deduction for corporations.  Shareholders receiving distributions in the form of
additional  shares  issued by a Series will be treated  for  federal  income tax
purposes as having received a distribution in an amount equal to the fair market
value on the date of distribution of the shares received.
    

    Interest on  indebtedness  incurred or continued to purchase or carry shares
of any Series  will not be  deductible  for federal  income tax  purposes to the
extent that the Series' distributions are exempt from federal income tax.

   
    Any gain or loss realized upon a sale or redemption of shares of a Series by
a shareholder  who is not a dealer in securities  generally will be treated as a
long-term capital gain or loss if the shares have been held for more than twelve
months 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.  Moreover,  any loss  realized by a
shareholder  upon the sale of shares of a Series held six months or less will be
disallowed  to the  extent  of any  exempt-interest  dividends  received  by the
shareholders with respect to such shares.  In addition,  no loss will be allowed
on the sale or other  disposition  of  shares  of a 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.
Individual  shareholders  will be  subject to  federal  income tax as  long-term
capital  gains at a maximum  rate of 28% in respect of shares held for more than
one year and at a maximum  rate of 20% in respect  of shares  held for more than
eighteen months.
    

                                       43

<PAGE>

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

    Shareholders  are urged to consult their tax advisors  concerning the effect
of  federal  income  taxes in their  individual  circumstances.  In  particular,
persons who may be  "substantial  users" (or  "related  persons" of  substantial
users)  of  facilities  financed  by  industrial  development  bonds or  private
activity bonds should consult their tax advisors before purchasing shares of any
Series.

    UNLESS A  SHAREHOLDER  INCLUDES A  TAXPAYER  IDENTIFICATION  NUMBER  (SOCIAL
SECURITY NUMBER FOR  INDIVIDUALS) ON THE ACCOUNT  APPLICATION AND CERTIFIES THAT
SUCH SHAREHOLDER IS NOT SUBJECT TO BACKUP WITHHOLDING,  EACH FUND IS REQUIRED TO
WITHHOLD AND REMIT TO THE U.S.  TREASURY A PORTION OF  NON-EXEMPT  DISTRIBUTIONS
AND OTHER REPORTABLE PAYMENTS TO THE SHAREHOLDER. THE RATE OF BACKUP WITHHOLDING
IS 31%. SHAREHOLDERS SHOULD BE AWARE THAT, UNDER REGULATIONS  PROMULGATED BY THE
INTERNAL  REVENUE  SERVICE,  A FUND  MAY BE FINED  UP TO $50  ANNUALLY  FOR EACH
ACCOUNT FOR WHICH A CERTIFIED TAXPAYER IDENTIFICATION NUMBER IS NOT PROVIDED. IN
THE EVENT THAT SUCH A FINE IS IMPOSED,  A FUND MAY CHARGE A SERVICE FEE OF UP TO
$50 THAT MAY BE DEDUCTED FROM THE  SHAREHOLDER'S  ACCOUNT AND OFFSET AGAINST ANY
UNDISTRIBUTED DIVIDENDS AND CAPITAL GAIN DISTRIBUTIONS.  EACH FUND ALSO RESERVES
THE  RIGHT TO CLOSE  ANY  ACCOUNT  WHICH  DOES  NOT  HAVE A  CERTIFIED  TAXPAYER
IDENTIFICATION  NUMBER WITH  RESPECT TO ANY  UNCERTIFIED  ACCOUNT IN ANY YEAR, A
CORRESPONDING CHARGE MAY BE MADE AGAINST THAT ACCOUNT.

CALIFORNIA TAXES

    In the opinion of Sullivan & Cromwell,  counsel to the Funds,  provided that
at the end of each  quarter of its taxable year at least 50% of the total assets
of the California  Quality or California  High-Yield Series consist of federally
tax-exempt obligations of the State of California and its political subdivisions
("California  Municipal  Securities"),  shareholders of each such Series who are
subject  to  California  State  taxation  on  dividends  will not be  subject to
California  personal income taxes on dividends from that Series  attributable to
interest received by each such Series on California Municipal Securities as well
as on certain other  federally  tax-exempt  obligations the interest on which is
exempt  from   California   personal  income  taxes.  To  the  extent  that  the
distributions  are derived  from other  income,  including  long- or  short-term
capital gains, such  distributions  will not be exempt from California  personal
income  taxation,  and,  further to the extent  that they  constitute  long-term
capital gain dividends they will be taxed as long-term gain to a shareholder.

    Interest on  indebtedness  incurred or continued to purchase or carry shares
of the California Quality or California High-Yield Series will not be deductible
for  California  personal  income  tax  purposes  to  the  extent  such  Series'
distributions are exempt from California personal income tax.

    Prospective investors should be aware that an investment in these Series may
not be suitable for persons who are not  residents of the State of California or
who do not receive income subject to income taxes of the State.

COLORADO TAXES

    In the opinion of Ireland,  Stapleton,  Pryor & Pascoe,  P.C.,  Colorado tax
counsel to the Municipal Fund, individuals, trusts, estates and corporations who
are holders of the Colorado  Series and who are subject to the  Colorado  income
tax will not be  subject to  Colorado  income  tax or the  Colorado  alternative
minimum  tax on Colorado  Series  dividends  to the extent  that such  dividends
qualify as  exempt-interest  dividends of a regulated  investment  company under
Section  852(b)(5) of the Code,  which are derived from interest income received
by the  Colorado  Series  on (a)  obligations  of the State of  Colorado  or its
political  subdivisions  which are issued on or after May  1,1980,  or if issued
before May 1,1980,  to the extent  such  interest  is  specifically  exempt from
income taxation un-

                                       44

<PAGE>

der  the  laws  of the  State  of  Colorado  authorizing  the  issuance  of such
obligations,  (b)  obligations  of the United States or its  possessions  to the
extent included in federal taxable income,  or (c) obligations of territories or
possessions of the United States to the extent  federal law exempts  interest on
such obligations from taxation by the states. To the extent that Colorado Series
distributions  are  attributable  to  sources  not  described  in the  preceding
sentence,  such as long or short-term capital gains, such distributions will not
be exempt from Colorado income tax and may be subject to Colorado's  alternative
minimum tax. There are no municipal  income taxes in Colorado.  As  intangibles,
shares in the Colorado Series are exempt from Colorado property taxes.

    Except during temporary defensive periods or when acceptable investments are
unavailable to the Colorado Series,  at least 80% of the value of the net assets
of the Colorado Series will be maintained in debt  obligations  which are exempt
from regular federal income tax and Colorado income tax.

    The Colorado Series will notify its  shareholders  within 60 days after  the
close of the year as to the  interest  derived  from  Colorado  obligations  and
exempt from the Colorado income tax.

FLORIDA TAXES

    Florida  does not  presently  impose an income tax on  individuals  and thus
individual shareholders of the Florida Series will not be subject to any Florida
state income tax on  distributions  received from the Florida  Series.  However,
Florida  imposes an  intangible  personal  property tax on shares of the Florida
Series owned by a Florida  resident on January 1 of each year unless such shares
qualify for an  exemption  from that tax.  The  Municipal  Trust has  received a
Technical  Assistance  Advisement  from the  State  of  Florida,  Department  of
Revenue,  to the effect  that shares of the  Florida  Series  owned by a Florida
resident  will be exempt from the Florida  Intangible  Personal  Property Tax so
long as the Florida  Series'  portfolio  includes on January 1 of each year only
assets,  such as Florida  tax-exempt  securities  and United  States  Government
securities,  that are exempt from the Florida Intangible  Personal Property Tax.
Corporate  shareholders  may be subject to Florida income taxes depending on the
portion of the income related to the Florida Series that is allocable to Florida
under applicable Florida law.

GEORGIA TAXES

    In the  opinion of King & Spalding,  Georgia  tax  counsel to the  Municipal
Fund, under existing Georgia law, shareholders of the Georgia Series will not be
subject to  Georgia  income  taxes on  dividends  with  respect to shares of the
Georgia Series to the extent that such distributions represent  "exempt-interest
dividends"   for  federal   income  tax  purposes  that  are   attributable   to
interest-bearing  obligations  issued by or on behalf of the State of Georgia or
its political  subdivisions,  or by the  governments  of Puerto Rico, the Virgin
Islands or Guam  (collectively,  "Georgia  Obligations"),  which are held by the
Georgia Series.  Dividends,  if any, derived from capital gains or other sources
generally  will be taxable to  shareholders  of the  Georgia  Series for Georgia
income tax purposes.

    Except during temporary defensive periods or when acceptable investments are
unavailable to the Georgia  Series,  at least 80% of the value of the net assets
of the Georgia  Series will be maintained in debt  obligations  which are exempt
from regular federal income tax and Georgia income taxes.

     The Georgia  Series will notify its  shareholders  within 60 days after the
close of the year as to the interest derived from Georgia Obligations and exempt
from Georgia income taxes.

LOUISIANA TAXES

    In the opinion of Liskow & Lewis,  Louisiana  tax  counsel to the  Municipal
Fund,  based upon a private  ruling  obtained from the  Louisiana  Department of
Revenue and Taxation (the "Department"),  and subject to the current policies of
the  Department,  shareholders  of the  Louisiana  Series who are  corporations;
individuals  and residents of the State of Louisiana;  and, for taxable  periods
beginning after December 31, 1996, trusts or estates;  all of whom are otherwise
subject to Louisiana  income tax, will not be subject to Louisiana income tax on
Louisiana Series dividends to the extent that such dividends are attributable to
interest on tax-exempt obligations of the State of Louisiana or its political or
governmental subdivisions, or its

                                       45

<PAGE>

governmental agencies or instrumentalities.  To the extent that distributions on
the Louisiana  Series are  attributable to sources other than those described in
the  preceding  sentence,  such  distributions,  including  but not  limited to,
long-term or short-term  capital gains, will not be exempt from Louisiana income
tax.

    Non-resident  individuals maintaining their domicile other than in the State
of  Louisiana  will not be subject to  Louisiana  income tax on their  Louisiana
Series dividends.

    Except during temporary defensive periods or when acceptable investments are
unavailable to the Louisiana  Series,  the Municipal Fund will maintain at least
80% of the value of the net assets of the Louisiana  Series in debt  obligations
which are exempt from federal income tax and exempt from Louisiana income tax.

    The Louisiana Series will notify its shareholders  within 60 days after  the
close of the year as to the interest derived from Louisiana  obligations and
exempt from Louisiana income tax.


MARYLAND TAXES

    In the opinion of Venable,  Baetjer and Howard, LLP, Maryland tax counsel to
the Municipal  Fund, as long as dividends paid by the Maryland Series qualify as
interest  excludable  under  Section  103 of the  Code and the  Maryland  Series
qualifies as a "regulated  investment  company"  under the Code,  the portion of
exempt-interest  dividends  that  represents  interest  received by the Maryland
Series  on  obligations  (a) of  Maryland  or  its  political  subdivisions  and
authorities,  or  (b)  of  the  United  States  or  an  authority,   commission,
instrumentality,  possession or territory of the United  States,  will be exempt
from Maryland  state and local income taxes when  allocated or  distributed to a
shareholder of the Maryland Series.

    Gain  realized  by the  Maryland  Series from the sale or exchange of a bond
issued by Maryland  or a political  subdivision  of  Maryland,  or of the United
States or an authority,  commission or instrumentality of the United States will
not be subject to Maryland state and local income taxes.

    To the extent that  distributions of the Maryland Series are attributable to
sources other than those described in the preceding sentences,  such as interest
received  by the  Maryland  Series on  obligations  issued by states  other than
Maryland,  income  earned  on  repurchase  contracts,  or  gains  realized  by a
shareholder  upon a  redemption  or  exchange of Maryland  Series  shares,  such
distributions will be subject to Maryland state and local income taxes.
       
    Interest on indebtedness incurred or continued (directly or indirectly) by a
shareholder  of the Maryland  Series to purchase or carry shares of the Maryland
Series will not be deductible  for Maryland  state and local income tax purposes
to the extent such interest is allocable to exempt-interest dividends.

    Except during temporary defensive periods or when acceptable investments are
unavailable to the Maryland Series,  at least 80% of the value of the net assets
of the Maryland Series will be maintained in debt  obligations  which are exempt
from regular  federal  income tax and are exempt from  Maryland  state and local
income taxes.

     The Maryland Series will notify its  shareholders  within 60 days after the
close of the year as to the  interest  derived  from  Maryland  obligations  and
exempt from Maryland state and local income taxes.


MASSACHUSETTS TAXES

    In the opinion of Palmer & Dodge, Massachusetts tax counsel to the Municipal
Fund, assuming that the Municipal Fund gives the notices described at the end of
this  section,  holders  of the  Massachusetts  Series  who are  subject  to the
Massachusetts  personal  income tax will not be subject to tax on  distributions
from the Massachusetts Series to the extent that these distributions  qualify as
exempt-interest  dividends  of a  regulated  investment  company  under  Section
852(b)(5) of the Code which are directly attributable to interest on obligations
issued  by the  Commonwealth  of  Massachusetts,  its  instrumentalities  or its
political  subdivisions or by the government of Puerto Rico or by its authority,
by the

                                       46


<PAGE>

government  of Guam or by its  authority,  or by the  government  of the  Virgin
Islands or its authority (collectively,  "Massachusetts Obligations"). Except to
the extent excluded as capital gain,  distributions  of income to  Massachusetts
holders of the Massachusetts  Series that are attributable to sources other than
those   described  in  the   preceding   sentence  will  be  includable  in  the
Massachusetts income of the holders of the Massachusetts  Series.  Distributions
will not be  subject  to tax to the extent  that they  qualify  as capital  gain
dividends which are  attributable to obligations  issued by the  Commonwealth of
Massachusetts,   its  instrumentalities  or  political  subdivisions  under  any
provision of law which exempts capital gain on the obligation from Massachusetts
income  taxation.  Distributions  which qualify as capital gain dividends  under
Section  852(b)(3)(C)  of the Code and which are  includable  in  Federal  gross
income  will be  includable  in the  Massachusetts  income  of a  holder  of the
Massachusetts Series as capital gain.

    Massachusetts   Series   dividends  are  not  excluded  in  determining  the
Massachusetts excise tax on corporations.

    Except during temporary defensive periods or when acceptable investments are
unavailable  to the  Massachusetts  Series,  the Municipal Fund will maintain at
least 80% of the value of the net  assets  of the  Massachusetts  Series in debt
obligations  which are exempt from regular federal income tax and  Massachusetts
personal income tax.

     The Massachusetts  Series will notify its shareholders within 60 days after
the  close  of the  year as to the  interest  and  capital  gains  derived  from
Massachusetts Obligations and exempt from Massachusetts personal income tax.

MICHIGAN TAXES

    In the opinion of Dickinson, Wright, Moon, Van Dusen & Freeman, Michigan tax
counsel to the Municipal Fund, holders of the Michigan Series who are subject to
the  Michigan  income  tax or single  business  tax will not be  subject  to the
Michigan income tax or single  business tax on Michigan Series  dividends to the
extent  that  such  distributions  qualify  as  exempt-interest  dividends  of a
regulated  investment  company  under  Section  852(b)(5)  of the Code which are
attributable to interest on tax-exempt  obligations of the State of Michigan, or
its  political  or  governmental  subdivisions,  its  governmental  agencies  or
instrumentalities  (as well as certain other federally  tax-exempt  obligations,
the interest on which is exempt from Michigan tax, such as, for example, certain
obligations  of Puerto  Rico)  (collectively,  "Michigan  Obligations").  To the
extent that  distributions  on the Michigan  Series are  attributable to sources
other  than those  described  in the  preceding  sentence,  such  distributions,
including,  but not limited to, long or short-term  capital  gains,  will not be
exempt from Michigan income tax or single business tax. The Michigan  Department
of Treasury has issued a bulletin stating that holders of interests in regulated
investment  companies  who are subject to the Michigan  intangibles  tax will be
exempt from the tax to the extent that the investment portfolio consists of U.S.
obligations  and  obligations  of the  State  of  Michigan  or of its  political
subdivisions.  In addition,  Michigan  Series shares owned by certain  financial
institutions or by certain other persons subject to the Michigan single business
tax  are  not  subject  to the  Michigan  intangibles  tax.  To the  extent  the
distributions  on the  Michigan  Series are not subject to Michigan  income tax,
they are not subject to the uniform city income tax imposed by certain  Michigan
cities.

    Except during temporary defensive periods or when acceptable investments are
unavailable to the Michigan Series,  at least 80% of the value of the net assets
of the Michigan Series will be maintained in debt  obligations  which are exempt
from regular federal income tax and Michigan income and single business taxes.

     The Michigan Series will notify its  shareholders  within 60 days after the
close of the year as to the  interest  derived  from  Michigan  Obligations  and
exempt from Michigan income tax.

MINNESOTA TAXES

   
    In the  opinion  of  Faegre &  Benson  LLP,  Minnesota  tax  counsel  to the
Municipal  Fund,  provided that the Minnesota  Series  qualifies as a "regulated
investment  company"  under the  Code,  and  subject  to the  discussion
    

                                       47

<PAGE>

in  the  paragraph   below,   shareholders  of  the  Minnesota  Series  who  are
individuals,  estates,  or trusts and who are subject to the  regular  Minnesota
personal  income  tax will  not be  subject  to such  regular  Minnesota  tax on
Minnesota  Series  dividends  to the extent that such  distributions  qualify as
exempt-interest  dividends  of a  regulated  investment  company  under  Section
852(b)(5)  of the Code which are  derived  from  interest  income on  tax-exempt
obligations  of the  State  of  Minnesota,  or  its  political  or  governmental
subdivisions,   municipalities,   governmental   agencies  or  instrumentalities
("Minnesota Sources"). The foregoing will apply, however, only if the portion of
the  exempt-interest  dividends from such Minnesota  Sources that is paid to all
shareholders  represents 95% or more of the  exempt-interest  dividends that are
paid by the Minnesota  Series.  If the 95% test is not met, all  exempt-interest
dividends  that are paid by the Minnesota  Series will be subject to the regular
Minnesota  personal  income tax. Even if the 95% test is met, to the extent that
exempt-interest  dividends that are paid by the Minnesota Series are not derived
from the Minnesota  Sources  described in the first sentence of this  paragraph,
such dividends  will be subject to the regular  Minnesota  personal  income tax.
Other  distributions of the Minnesota Series,  including  distributions from net
short-term  and  long-term  capital  gains,  are  generally  not exempt from the
regular Minnesota personal income tax.

   
    Legislation  enacted in 1995 provides that it is the intent of the Minnesota
legislature that interest income on obligations of Minnesota governmental units,
including   obligations  of  the  Minnesota   Sources   described   above,   and
exempt-interest  dividends  that  are  derived  from  interest  income  on  such
obligations,  be included in the net income of individuals,  estates, and trusts
for  Minnesota  income tax  purposes  if it is  judicially  determined  that the
exemption  by  Minnesota  of such  interest  or such  exempt-interest  dividends
unlawfully  discriminates against interstate commerce because interest income on
obligations of governmental  issuers located in other states, or exempt-interest
dividends derived from such obligations,  is so included. This provision applies
to  taxable  years that begin  during or after the  calendar  year in which such
judicial decision becomes final, regardless of the date on which the obligations
were issued,  and other  remedies apply for previous  taxable years.  The United
States Supreme Court in 1995 denied  certiorari in a case in which an Ohio state
court  upheld  an  exemption  for  interest   income  on   obligations  of  Ohio
governmental  issuers,  even though  interest  income on obligations of non-Ohio
governmental  issuers,  was subject to tax. In 1997,  the United States  Supreme
Court denied  certiorari  in a  subsequent  case from Ohio,  involving  the same
taxpayer  and the  same  issue,  in which  the Ohio  Supreme  Court  refused  to
reconsider  the merits of the case on the ground that the  previous  final state
court  judgment  barred any claim  arising out of the  transaction  that was the
subject of the previous  action.  It cannot be predicted  whether a similar case
will be brought in  Minnesota  or  elsewhere,  or what the  outcome of such case
would be.
    

    Minnesota  presently  imposes an  alternative  minimum  tax on  individuals,
estates,  and  trusts  that  is  based,  in  part,  on such  taxpayers'  federal
alternative minimum taxable income, which includes federal tax preference items.
The Code provides that interest on specified private activity bonds is a federal
tax  preference  item,  and  that an  exempt-interest  dividend  of a  regulated
investment  company  constitutes a federal tax preference  item to the extent of
its  proportionate  share  of the  interest  on  such  private  activity  bonds.
Accordingly,  exempt-interest  dividends that are  attributable  to such private
activity bond interest,  even though they are derived from the Minnesota Sources
described  above,  will be  included  in the  base  upon  which  such  Minnesota
alternative  minimum  tax is  computed.  In  addition,  the  entire  portion  of
exempt-interest  dividends  that is  received by such  shareholders  and that is
derived from sources other than the Minnesota  Sources  described  above is also
subject to the Minnesota  alternative minimum tax. Further,  should the 95% test
that is  described  above fail to be met, all of the  exempt-interest  dividends
that are paid by the Minnesota  Series,  including all of those that are derived
from the Minnesota  Sources  described  above,  will be subject to the Minnesota
alternative minimum tax, in the case of shareholders of the Minnesota Series who
are individuals, estates or trusts.


                                       48


<PAGE>

    Subject to certain  limitations  that are set forth in the Minnesota  rules,
Minnesota  Series  dividends,  if any, that are derived from interest on certain
United  States  obligations  are not subject to the regular  Minnesota  personal
income tax or the Minnesota alternative minimum tax, in the case of shareholders
of the Minnesota Series who are individuals, estates, or trusts.

    Minnesota Series distributions, including exempt-interest dividends, are not
excluded in  determining  the Minnesota  franchise tax on  corporations  that is
measured by taxable income and alternative  minimum  taxable  income.  Minnesota
Series  distributions  may  also be  taken  into  account  in  certain  cases in
determining the minimum fee that is imposed on corporations, S corporations, and
partnerships.

    Except during temporary defensive periods or when acceptable investments are
unavailable to the Minnesota Series, at least 80% of the value of the net assets
of the Minnesota Series will be maintained in debt obligations  which are exempt
from the regular  federal income tax. Such debt  obligations  may,  however,  be
subject  to the  federal  alternative  minimum  tax. A similar  percentage  will
generally also apply with respect to the regular Minnesota  personal income tax,
and such debt  obligations may likewise be subject to the Minnesota  alternative
minimum tax, in each case subject to the entire  discussion above. The Minnesota
Series will invest so that the 95% test described above is met.

    The Minnesota Series will notify its  shareholders  within 30 days after the
close of the year as to the interest  derived  from  Minnesota  obligations  and
exempt from the Minnesota personal income tax, subject to the discussion above.

MISSOURI TAXES

    In the  opinion of Bryan Cave LLP,  Missouri  tax  counsel to the  Municipal
Fund,  dividends  distributed to individual  shareholders of the Missouri Series
will be exempt from the Missouri  personal  income tax imposed by Chapter 143 of
the  Missouri  Revised  Statutes  to the extent that such  dividends  qualify as
exempt  interest  dividends  of a regulated  investment  company  under  Section
852(b)(5) of the Code and are derived from interest on  obligations of the State
of Missouri or any of its political  subdivisions  or authorities or obligations
issued  by  the  government  of  Puerto  Rico  or its  authority  (collectively,
"Missouri Obligations"). Capital gain dividends, as defined in Section 852(b)(3)
of the Code,  distributable by the Fund to individual  resident  shareholders of
the Missouri Series,  to the extent includable in federal adjusted gross income,
will be subject to Missouri income  taxation.  Shares in the Missouri Series are
not subject to Missouri personal property taxes.

    Dividends  paid by the Missouri  Series,  if any, that do not qualify as tax
exempt  dividends  under  Section  852 (b)(5) of the Code,  will be exempt  from
Missouri  income tax only to the extent that such  dividends  are  derived  from
interest on certain  U.S.  obligations  that the State of Missouri is  expressly
prohibited from taxing under the laws of the United States.  The portion of such
dividends  that is not  subject  to  taxation  by the State of  Missouri  may be
reduced by interest,  or other expenses, in excess of $500 paid or incurred by a
shareholder  in any taxable  year to purchase  or carry  shares of the  Missouri
Series of the  Municipal  Fund or other  investments  producing  income  that is
includable in federal gross income, but exempt from Missouri income tax.

    Except during temporary defensive periods or when acceptable investments are
unavailable to the Missouri Series,  at least 80% of the value of the net assets
of the Missouri Series will be maintained in debt  obligations  which are exempt
from regular federal income tax and Missouri personal income tax.

     The Missouri Series will notify its  shareholders  within 60 days after the
close of the year as to the  interest  derived  from  Missouri  Obligations  and
exempt from the Missouri personal income tax.

NEW JERSEY TAXES

    In the opinion of McCarter & English,  New Jersey  counsel to the New Jersey
Fund, income  distributions  paid from a "qualified  investment fund" are exempt
from  the  New  Jersey  personal  income  tax,  to the  extent  attributable  to
tax-exempt  obligations  specified  by New Jersey  law.  As defined in  N.J.S.A.
54A:6-14.1, a "qualified investment fund" is any investment or trust company, or
series of such  investment  company or trust  registered with the Securities and
Exchange  Commission,

                                       49


<PAGE>

which  for  the  calendar  year in  which a  distribution  is  paid,  has (i) no
investments other than  interest-bearing  obligations,  obligations  issued at a
discount, and cash and cash items, including receivables, and financial options,
futures,  forward contracts,  or other similar financial  instruments related to
interest-bearing  obligations,  obligations issued at a discount or bond indices
related  thereto  (such  financial  options,  etc.  being  referred to herein as
"Financial  Instruments"),  and (ii)  which  has at least  80% of the  aggregate
principal amount of all its investments, excluding Financial Instruments, to the
extent such  instruments  are authorized by section 851(b) of the Code, cash and
cash items, including receivables, invested in obligations issued by New Jersey,
or in  obligations  that are free from state or local  taxation under New Jersey
and federal laws such as obligations  issued by the  governments of Puerto Rico,
Guam or the Virgin Islands ("Municipal  Securities").  Interest income and gains
realized by the New Jersey Fund upon  disposition of obligations and distributed
to the  shareholders  are exempt from the New Jersey  personal income tax to the
extent attributable to Municipal Securities. Gains resulting from the redemption
or sale of shares  of the New  Jersey  Fund  would  also be exempt  from the New
Jersey personal income tax.

    The New Jersey  personal income tax is not applicable to  corporations.  For
all corporations subject to the New Jersey Corporation Business Tax, interest on
Municipal  Securities  is  included  in the net income tax base for  purposes of
computing  the  corporation  business  tax.  Furthermore,   any  gain  upon  the
redemption or sale of shares by a corporate  shareholder is also included in the
net income tax base for purposes of computing the Corporation Business Tax.

    The New Jersey Fund will notify shareholders by February 15 of each calendar
year as to the amounts of all such dividends and distributions  which are exempt
from federal income taxes and New Jersey personal income tax and the amounts, if
any,  which are  subject to such  taxes.  Shareholders  are,  however,  urged to
consult  with  their  own tax  advisors  as to the  federal,  state or local tax
consequences in their specific circumstances.

     Prospective  investors  should  be  aware  that  an  investment  in a state
municipal fund may not be suitable for persons who do not receive income subject
to income taxes of such state.


NEW YORK STATE AND CITY TAXES

    In the  opinion of  Sullivan &  Cromwell,  counsel to the Funds,  holders of
shares of the New York  Series who are subject to New York State and City tax on
dividends  will not be subject to New York State and City personal  income taxes
on New York Series  dividends to the extent that such  distributions  qualify as
exempt-interest  dividends  under  Section  852(b)(5) of the Code and  represent
interest income attributable to federally tax-exempt obligations of the State of
New York and its  political  subdivisions  (as well as certain  other  federally
tax-exempt  obligations  the interest on which is exempt from New York State and
City personal income taxes such as, for example,  certain  obligations of Puerto
Rico) (collectively,  "New York Obligations").  To the extent that distributions
on the New  York  Series  are  derived  from  other  income,  including  long or
short-term  capital gains, such  distributions  will not be exempt from State or
City personal income taxes.

    Dividends  on the New York Series are not excluded in  determining  New York
State or City franchise taxes on corporations and financial institutions.

    Except during temporary defensive periods or when acceptable investments are
unavailable  to the New York Series,  the Municipal  Fund will maintain at least
80% of the value of the net  assets of the New York  Series in debt  obligations
which are exempt  from  regular  federal  income tax and New York State and City
personal income taxes.

    The Series will notify its  shareholders  within 45 days after  the close of
the year as to the interest  derived from  New York  Obligations and exempt from
New York State and City personal income taxes.

NORTH CAROLINA TAXES

    In the opinion of Horack,  Talley, Pharr & Lowndes, P.A., tax counsel to the
North  Carolina  Series,   distributions  from  the  North  Carolina  Series  to
shareholders  subject 


                                       50


<PAGE>

to North Carolina income taxes will not be taxable for North Carolina income tax
purposes to the extent the distributions  either (i) qualify as  exempt-interest
dividends of a regulated  investment company under the Code and are attributable
to  interest  on  obligations  issued  by the  State of North  Carolina  and its
political  subdivisions or (ii) are dividends attributable to interest on direct
obligations of the U.S.  government  and agencies and  possessions of the United
States, so long as in both cases the North Carolina Series provides a supporting
statement to the  shareholders  designating  the portion of the dividends of the
North Carolina  Series  attributable  to interest on  obligations  issued by the
State of North Carolina and its political  subdivisions or direct obligations of
the U.S.  government and agencies and  possessions of the United States.  In the
absence of such a statement,  the total amount of the dividends  will be taxable
for North  Carolina  income tax purposes.  Distributions  attributable  to other
sources,   including  exempt-interest  dividends  attributable  to  interest  on
obligations of states other than North  Carolina and the political  subdivisions
of such  other  states  as well as  capital  gains,  will be  taxable  for North
Carolina income tax purposes.

    The North Carolina Series will notify its shareholders  within 60 days after
the close of its taxable year as to the amount of dividends and distributions to
the  shareholders  of the North  Carolina  Series  which are  exempt  from North
Carolina  income taxes and the dollar amount,  if any, which is subject to North
Carolina income taxes.

OHIO TAXES

   
    In the opinion of Squire,  Sanders & Dempsey L.L.P., Ohio tax counsel to the
Municipal Fund,  holders of the Ohio Series who are subject to the Ohio personal
income  tax,  the net income  base of the Ohio  corporation  franchise  tax,  or
municipal  income or school  district  taxes in Ohio will not be subject to such
taxes on  dividend  distributions  with  respect  to shares  of the Ohio  Series
("Distributions")   to  the  extent  that  such   distributions   are   properly
attributable  to  interest   (including  accrued  original  issue  discount)  on
obligations issued by or on behalf of the State of Ohio, political  subdivisions
thereof, or agencies or instrumentalities thereof ("Ohio Obligations"), provided
that the Ohio Series qualifies as a "regulated  investment  company" for federal
income tax purposes and that at all times at least 50% of the value of the total
assets of the Ohio Series consists of Ohio Obligations or similar obligations of
other  states  or  their  subdivisions.  It is  assumed  for  purposes  of  this
discussion of Ohio taxes that these  requirements  are satisfied.  Shares of the
Ohio  Series  will be  included  in a  corporation's  tax base for  purposes  of
computing the Ohio corporation franchise tax on the net worth basis.

    Distributions that are properly attributable to gain from the sale, exchange
or other disposition of Ohio Obligations held by the Ohio Series are not subject
to the Ohio  personal  income tax,  the net income base of the Ohio  corporation
franchise tax, or municipal income or school district taxes in Ohio.

    Distributions  properly  attributable  to interest on  obligations of Puerto
Rico,  the Virgin  Islands or Guam,  the  interest on which is exempt from state
income  taxes  under the laws of the  United  States  are  exempt  from the Ohio
personal income tax and municipal income and school district taxes in Ohio, and,
provided  such  interest is excluded  from gross  income for Federal  income tax
purposes,  are  excluded  from  the  net  income  base of the  Ohio  Corporation
franchise tax.

    The Ohio Series is not subject to the Ohio personal  income tax or municipal
income  or school  district  taxes in Ohio.  The Ohio  Series is not  subject to
corporation franchise tax or the Ohio dealers in intangibles tax, provided that,
if the Ohio Series has a significant nexus to the State of Ohio to be subject to
Ohio  taxation,  then such entity shall be exempt from taxes only if it complies
with certain reporting requirements.
    

    Except during temporary defensive periods or when acceptable investments are
unavailable to the Ohio Series, the Municipal Fund will maintain at least 80% of
the value of the net  assets of the Ohio  Series in debt  obligations  which are
exempt from regular  federal income tax and the Ohio personal income tax and the
net income base of the Ohio corporation franchise tax.

    The Ohio Series will notify its shareholders  within 60 days after the close
of the year as to the status for Ohio tax purposes of distributions with respect
to shares of the Ohio Series.

OREGON TAXES

    In the opinion of  Schwabe,  Williamson  & Wyatt,  Oregon tax counsel to the
Municipal Fund, under present law, individual  shareholders of the Oregon Series
will not be subject to Oregon  personal income taxes on  distributions  received
from the Oregon  Series to the extent  that such  distributions  (1)  qualify as
"exempt-interest  dividends"  under  Section  852 (b)(5) of the Code and (2) are
derived  from  interest  on  obligations  of the  State of  Oregon or any of its
political  subdivisions  or  authorities  or from interest on obligations of the
governments of Puerto Rico,  Guam,  the Virgin  Islands or the Northern  Mariana
Islands (collectively, "Oregon Obligations"). Other distributions, including any
long-term  and  short-term  capital  gains,  will  generally  not be exempt from
personal income taxes in Oregon.

    No portion of  distributions  from the Oregon  Series are exempt from Oregon
excise tax on corporations. However, shares of the Oregon Series are not subject
to Oregon property tax.

    Except during temporary defensive periods or when acceptable investments are
unavailable to the Oregon Series, at least 80% of the value of the net assets of
the Oregon Series will be maintained in debt obligations,  the interest payments
of which are exempt from regular  federal income tax and Oregon  personal income
taxes.

     The Oregon  Series  will notify its  shareholders  within 60 days after the
close of the year as to the interest derived from Oregon  Obligations and exempt
from Oregon personal income taxes.

PENNSYLVANIA TAXES

    In the  opinion of  Ballard  Spahr  Andrews &  Ingersoll,  Pennsylvania  tax
counsel to the Pennsylvania  Fund,  individual  shareholders of the Pennsylvania
Fund who are subject to the Pennsylvania personal income tax will not be subject
to Pennsylvania  personal income tax on distributions from the Pennsylvania Fund
to the extent that such  distributions  are  attributable  to  interest  paid on
Pennsylvania Municipal Securities or U.S. Government obligations.  Distributions
attributable to most other sources, including distributions attributable to gain
on the sale of such instruments,  will not be exempt from Pennsylvania  personal
income tax.

    The same  rules  apply  under the tax  imposed  by the  Philadelphia  School
District  on the  unearned  income of  Philadelphia  residents,  except that all
capital gain distributions are exempt from the School District tax regardless of
the source from which they are paid.

    Corporate  shareholders  who are subject to the  Pennsylvania  corporate net
income tax will not be subject to corporate net income tax on distributions from
the Pennsylvania  Fund that qualify as  "exempt-interest  dividends" for federal
income tax purposes or are derived from interest on U.S. Government obligations.

    Individual  shareholders  of the  Pennsylvania  Fund who are  subject to the
Pennsylvania  personal  property tax will be exempt from  Pennsylvania  personal
property  tax on their  shares of the  Pennsylvania  Fund to the extent that the
Pennsylvania Fund portfolio  consists of Pennsylvania  Municipal  Securities and
U.S. Government obligations on the annual assessment date.  Corporations are not
subject to Pennsylvania personal property taxes.

    Shareholders  will receive an annual  Statement  of Account and  information
regarding the federal and  Pennsylvania  income tax status of all  distributions
made  during  the  year.   Information  will  also  be  provided  to  individual
Pennsylvania shareholders regarding the portion of the value of their shares, if
any, subject to Pennsylvania personal property tax.

    Prospective investors should be aware that an investment in the Pennsylvania
Fund may not be  suitable  for  persons  who are not  residents  of the State of
Pennsylvania  or who do not receive income subject to income taxes of the State.
Investors  should  also be aware that there is  litigation  in  progress  in the
Pennsylvania  courts that may result in the personal property tax being declared
unconstitutional in whole or in part.

SOUTH CAROLINA TAXES

    In the  opinion  of  Sinkler  & Boyd,  South  Carolina  tax  counsel  to the
Municipal  Fund,  shareholders  of the South Carolina  Series who are subject to
South Carolina  individual or corporate income taxes will not be subject to such
taxes on South  Carolina  Series'  dividends  to the extent that such  dividends
qualify  as either  (1)  exempt-interest  dividends  of a  regulated

                                       52

<PAGE>

investment  company under Section  852(b)(5) of the Code, which are derived from
interest on tax-exempt  obligations of the State of South Carolina or any of its
political  subdivisions  or on obligations of the Government of Puerto Rico that
are exempt from federal  income tax; or (2)  dividends  derived from interest or
dividends  on  obligations  of the  United  States  and  its  possessions  or on
obligations  or  securities  of any  authority or  commission  exempt from state
income taxes under the laws of the United States (collectively,  "South Carolina
Obligations").  To the extent  that South  Carolina  Series'  distributions  are
attributable to other sources,  such as long or short-term  capital gains,  such
distributions will not be exempt from South Carolina taxes.

    Except during temporary defensive periods or when acceptable investments are
unavailable to the South Carolina  Series,  at least 80% of the value of the net
assets of the South Carolina Series will be maintained in debt obligations which
are exempt from regular federal income tax and South Carolina income tax.

    The South Carolina Series will notify its shareholders  within 60-days after
the close of the year as to the interest derived from South Carolina Obligations
and exempt from South Carolina income taxes.

OTHER STATE AND LOCAL TAXES

    The  exemption of interest on municipal  securities  for federal  income tax
purposes does not  necessarily  result in exemption under the income tax laws of
any state or city.  Except as noted above with  respect to a  particular  state,
distributions  from a Series may be taxable to  investors  under state and local
law  even  though  all or a part  of  such  distributions  may be  derived  from
federally  tax-exempt  sources or from obligations  which, if received directly,
would be exempt  from such  income  tax.  In some  states,  shareholders  of the
National Series may be afforded  tax-exempt  treatment on  distributions  to the
extent they are derived from  municipal  securities  issued by that state or its
localities.  Prospective  investors  should  be aware  that an  investment  in a
certain  Series may not be suitable  for persons  who are not  residents  of the
designated  state or who do not receive  income  subject to income taxes in that
state. Shareholders should consult their own tax advisors.

ADVERTISING A SERIES' PERFORMANCE

    From time to time, a Series advertises its "yield," "tax equivalent  yield,"
"average  annual total  return" and "total


                                       54

<PAGE>

return,"  each of which is  calculated  separately  for each Series' Class A and
Class D shares.  THESE  FIGURES  ARE BASED ON  HISTORICAL  EARNINGS  AND ARE NOT
INTENDED TO INDICATE FUTURE  PERFORMANCE.  The "yield" of a Series' class refers
to the income  generated by an  investment  in the Series 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
"tax equivalent  yield" is calculated  similarly to the "yield," except that the
yield is increased  using a stated  income tax rate to  demonstrate  the taxable
yield  necessary to produce an after-tax  yield  equivalent  to the Series.  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 year, five years, and ten years or since the inception of
the Series),  i.e.,  the average  annual  compound rate of return,  assuming the
payment of the maximum sales load, if any,  when the  investment  was first made
and that all  distributions  and dividends by the Series were  reinvested on the
reinvestment  dates during the period.  "Total return" is calculated  with these
same assumptions and shows the aggregate return on an investment in a class over
a specified period (one year, five years and ten years or since the inception of
the Series).  Class A total return and average  annual total return  quoted from
time to time are not adjusted for periods prior to commencement dates,  December
27, 1990, in the case of the Florida Series, and January 1, 1993, in the case of
the California High-Yield Series,  California Quality Series, and each Series of
the Municipal  Fund,  for the annual  administration,  shareholder  services and
distribution fee. Such fee, if reflected,  would reduce the performance  quoted.
The waiver by the  Manager  of its fees and  reimbursement  of certain  expenses
during certain periods (as set forth under "Financial  Highlights" herein) would
positively affect the performance results quoted.

    From  time to time,  reference  may be made in  advertising  or  promotional
material to mutual fund rankings  prepared by Lipper  Analytical  Service,  Inc.
("Lipper"),  an independent  reporting  service that monitors the performance of
mutual funds.  Lipper ranks funds in various  categories  by making  comparative
calculations using total return. Each Series may quote its Lipper ranking in the
Municipal Bond Fund category or the Single State Municipal Bond Fund category or
its Lipper  ranking  for all  municipal  bond  funds  monitored  by  Lipper.  In
addition,  each class of a Series may  compare  its total  return over a certain
period with the average  performance of all funds in these Lipper categories for
the same period.  In calculating the total return of a Series' Class A and Class
D  shares,   the  Lipper  analysis  assumes  investment  of  all  dividends  and
distributions  paid but does not take into account  applicable  sales  loads.  A
Series may also refer in  advertisements,  or in other  promotional  material to
articles,  comments,  listings  and  columns in the  financial  and other  press
pertaining to a Series' performance.  Examples of such financial and other press
publications  include  BARRON'S,  BUSINESS WEEK,  CDA/WIESENBERGER  MUTUAL FUNDS

ORGANIZATION AND CAPITALIZATION

    Each Fund is a non-diversified,  open-end management  investment company, as
defined in the 1940 Act.  The  Municipal  Fund was  incorporated  in Maryland on
August  8,  1983.  The  Municipal  Trust was  established  under the laws of the
Commonwealth of Massachusetts by a Declaration of Trust dated July 27, 1984. The
New Jersey Fund was incorporated in Maryland on March 13, 1987. The Pennsylvania
Fund was organized as an unincorporated trust under the laws of the Commonwealth
of Pennsylvania by a Declaration of Trust dated May 13, 1986.

    The Directors or Trustees of the Funds have authority to create and classify
shares of capital  stock or  beneficial  interest  in separate  Series,  without
further action by  shareholders.  The  Declarations of Trust of the Penn-


                                       55


<PAGE>

sylvania Fund and the Municipal  Trust permit the Trustees to issue an unlimited
number of full and fractional shares of beneficial  interest in separate Series.
To date,  shares of thirteen  Series of the Municipal  Fund,  four Series of the
Municipal  Trust,  one  Series  of the New  Jersey  Fund and one  Series  of the
Pennsylvania Fund have been authorized, which shares constitute the interests in
the Series described herein.  Further series may be added in the future. Each of
the Series'  capital stock or shares of  beneficial  interest has a par value of
$.001 per share and is divided  into two  classes.  Each  share of each  Series'
Class A and Class D common stock or beneficial interest, as applicable, is equal
as to earnings,  assets and voting privileges,  except that each class bears its
own separate distribution and, potentially, certain other class expenses and has
exclusive  voting  rights with respect to any matter to which a separate vote of
any class is required  by the 1940 Act or  applicable  state law.  Each Fund has
adopted a plan (the "Multiclass Plan") pursuant to Rule 18f-3 under the 1940 Act
permitting  the  issuance  and sales of  multiple  classes of common  stock,  or
beneficial  interest.  In  accordance  with the  Articles  of  Incorporation  or
Declaration  of Trust of each  Fund,  the Board of  Directors  or  Trustees  may
authorize  the  creation of  additional  classes of common  stock or  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.  All shares have  noncumulative  voting  rights for the
election of directors or trustees,  as  applicable.  Each  outstanding  share is
fully paid and  non-assessable,  and each is freely  transferable.  There are no
liquidation, conversion or preemptive rights.

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

    The shareholders of a Massachusetts  business trust (the Municipal Trust) or
a   Pennsylvania   trust  (the   Pennsylvania   Fund),   could,   under  certain
circumstances,  be  held  personally  liable  as  partners  of its  obligations.
However,  the  Declaration  of  Trust  of each of the  Municipal  Trust  and the
Pennsylvania Fund,  contains an express disclaimer of shareholder  liability for
acts or  obligations  of the Trusts and also  provides for  indemnification  and
reimbursement  of  expenses  out of the  Trusts,  or  Series  thereof,  for  any
shareholder  held  personally  liable for  obligations  of the Trust,  or Series
thereof.

    THERE IS A POSSIBILITY  THAT ONE FUND MIGHT BE LIABLE FOR ANY  MISSTATEMENT,
INACCURACY,  OR INCOMPLETE  DISCLOSURE IN THIS  PROSPECTUS  CONCERNING ANY OTHER
FUND  CONTAINED  HEREIN.  BASED ON THE  ADVICE OF  COUNSEL,  HOWEVER,  THE FUNDS
BELIEVE THAT THE POTENTIAL LIABILITY OF EACH FUND WITH RESPECT TO THE DISCLOSURE
IN THIS PROSPECTUS EXTENDS ONLY TO THE DISCLOSURE RELATING TO SUCH FUND.

                              TERMS AND CONDITIONS
                           GENERAL ACCOUNT INFORMATION
      Investments  will  be  made  in as  many  shares  of a  Series,  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 your  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.  in writing at least five business
days prior to the payable  date.  Stock  certificates  will not be issued unless
requested.   Replacement  stock  certificates  and  certain  waiver  of  probate
procedures 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.  CheckS  in the  amount  specified  will  be  drawn  automatically  on the
shareholder's bank on the fifth day of each month unless otherwise specified (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 close of
business  on the same  date.  By  utilizing  the  Invest-A-Check(R)  Service  to
establish an account,  you are agreeing to continue the Service until the Fund's
minimum  investment  amount is met. If you elect to canceL the Service  prior to
meeting the minimum,  your account may be subject to closure.  If a check is not
honored by the  shareholder's  bank,  or if the value of shares held falls below
the required minimum,  the Service will be suspended.  In the event that a check
is returned  marked  "unpaid,"  Seligman  Data Corp.  will cancel the  purchase,
redeem  shares held in your  account  for an amount  sufficient  to  reimburse a
Series for any loss it may have incurred as a result, and charge a $10.00 return
check fee. This fee will be deducted  from the  shareholder's  account.  Service
will  be  reinstated  upon  written   request   indicating  that  the  cause  of
interruption  has  been  corrected.   The  Service  may  be  terminated  by  the
shareholder  or  Seligman  Data  Corp.  at  any  time  by  written  notice.  The
shareholder  agrees to hold the Funds and their  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 the shareholder  exchanges all of the shares from one
Seligman  Mutual  Fund  to  another,  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 Fund from which
the  exchange  was  made.   Accounts   established  in   conjunction   with  the
Invest-A-Check(R)  servicE must be  accompanied  by a check for at least $100 in
connection  with the monthly  investment  option or a check for at least $250 in
connection with the quarterly investment option.

                        AUTOMATIC CASH WITHDRAWAL SERVICE
      A  sufficient  number of full and  fractional  shares  will be redeemed to
provide the amount  required for a scheduled  payment and any  applicable  CDSL.
Redemptions  will be made at the  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 D 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 may be subject to a CDSL if made within 18 months of purchase
of such shares.  Under this  Service,  a Class D  shareholder  who requests both
dividends and capital gain distributions in additional shares may withdraw up to
10% of the value of the shareholder's fund account (at the time of election) per
annum,  without the  imposition of a CDSL. A minimum  payment  amount of $50 per
cycle is needed to establish this Service. The 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.  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 to you because of the payment
of duplicative sales loads, if applicable. For this reason, additional purchases
of Fund 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.  The  shareholder  may
include the total asset value of shares of the  Seligman  Mutual Funds (on which
an  initial  sales  load was  paid)  owned as of the date of a Letter  of Intent
toward the  completion of the Letter.  If the total amount  invested  within the
thirteen-month  period does not equal or exceed the specified  minimum purchase,
you 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 your 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
shareholder and that the required additional escrowed shares are being furnished
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 a sales
load may be taken into account in completing a Letter of Intent, or for Right of
Accumulation.  However,  shares  of the 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 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 redemption within 18 months of purchase 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  hereby authorizes Mellon Bank, N.A. to honor checks drawn
by the  shareholder  and to  effect a  redemption  of  sufficient  shares in the
shareholder's  account to cover  payment of the check and any  applicable  CDSL.
Shares in one  Series  cannot be  redeemed  to cover a check  written on another
Series.

      Mellon Bank, N.A. shall be liable only for its own negligence. A Fund will
not be liable for any loss,  expense or cost  arising out of check  redemptions.
Each 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 OF SHARES  PURCHASED BY
CHECK (UNLESS  CERTIFIED)  WILL BE PERMITTED UNTIL THE FUND RECEIVES NOTICE THAT
THE CHECK HAS CLEARED WHICH MAY BE UP TO 15 DAYS FROM THE CREDIT OF THOSE SHARES
TO A SHAREHOLDER'S ACCOUNT.

         This Statement of Additional  Information  expands upon and supplements
the  information  contained  in the  current  Prospectus  of the  Series,  dated
February 1, 1998. It should be read in conjunction  with the  Prospectus,  which

itself a Prospectus,  is  incorporated  by reference  into the Prospectus in its
entirety.
    

         The  High-Yield  Series and  Quality  Series  each offer two classes of
shares.  Class A shares may be purchased at net asset value plus a 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 eighteen
months of  purchase.  Class D shares may be purchased at net asset value and are
subject to a CDSL of 1% if redeemed within one year.

         Each  share  of  Class A and  Class D  represents  an  identical  legal
interest  in the  investment  portfolio  of each  Series and has the same rights
except for certain  class  expenses and except that Class D shares bear a higher
distribution  fee that  generally will cause the 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 and  Class D shares  have  identical  legal  rights,  the  different
expenses borne by each Class will result in different dividends. The two classes
also have different exchange privileges.

                         SELIGMAN MUNICIPAL SERIES TRUST

     The High-Yield  Series and Quality Series are series of Seligman  Municipal
Series Trust (the "Trust"),  a non-diversified  open-end  management  investment
company, or mutual fund, organized as an unincorporated business trust under the
laws of Massachusetts that commenced operations in 1984.

                    INVESTMENT OBJECTIVES, POLICIES AND RISKS

     The High-Yield Series and Quality Series each seek to provide income exempt
from regular  federal  income taxes and the personal  income taxes of California
consistent  with  preservation  of capital with  consideration  given to capital
gain.

CALIFORNIA MUNICIPAL SECURITIES

     California  Municipal  Securities include notes, bonds and commercial paper
issued by or on behalf of the State of California,  its political  subdivisions,
agencies,  and  instrumentalities,  the interest on which is exempt from regular
federal income taxes and California state personal income taxes. Such securities
are traded  primarily  in an  over-the-counter  market.  Each Series may invest,
without percentage limitations,  in certain private activity bonds, the interest
on which is treated as a preference item for purposes of the alternative minimum
tax. See "California Municipal Securities" in the Prospectus.

     Under  the   Investment   Company  Act  of  1940  (the  "1940  Act"),   the
identification  of the issuer of  municipal  bonds,  notes or  commercial  paper
depends  on the  terms and  conditions  of the  obligation.  If the  assets  and
revenues of an agency, authority, instrumentality or other political subdivision
are  separate  from those of the  government  creating the  subdivision  and the
obligation  is backed only by the assets and revenues of the  subdivision,  such
subdivision  is  regarded  as the  sole  issuer.  Similarly,  in the  case of an
industrial  development  revenue bond or pollution  control revenue bond, if the
bond is backed only by the assets and revenues of the nongovernmental  user, the
nongovernmental  user is  regarded  as the sole  issuer.  If in either  case the
creating government or another entity guarantees an obligation,  the security is
treated  as an  issue  of such  guarantor  to the  extent  of the  value  of the
guarantee.

     Municipal  bonds are issued to obtain  funds for various  public  purposes,
including  the  construction  of a wide  range  of  public  facilities  such  as
airports, bridges, highways,  housing, hospitals, mass transportation,  schools,
streets, water and sewer works, and gas and electric utilities.  Municipal bonds
also may be issued in connection with the refunding of outstanding  obligations,
obtaining funds to lend to other public institutions,  and for general operating
expenses.  Industrial development bonds, which are considered municipal bonds if
the  interest  paid  thereon is exempt  from  regular  federal  income tax (such
interest,  however,  may be subject to the federal alternative minimum tax), are
issued by or on behalf of public  authorities to obtain funds to provide various
privately-operated  facilities for business and manufacturing,  housing, sports,
pollution control, and for airport, mass transit, port and parking facilities.

     The  two  principal   classifications   of  municipal  bonds  are  "general
obligation" and "revenue."  General obligation bonds are secured by the issuer's
pledge of its full faith,  credit and taxing  power for the payment of principal
and interest.  Revenue  bonds are payable only from the revenues  derived from a
particular  facility or class of facilities or, in some cases, from the proceeds
of a special excise tax or other specific  revenue source.  Although  industrial
development  bonds  ("IDBs")  are  issued  by  municipal  authorities,  they are
generally  secured by the revenues derived from payments of the industrial user.
The payment of principal and interest on IDBs is dependent solely on the ability
of the user of the  facilities  financed  by the  bonds  to meet  its  financial
obligations and the pledge, if any, of real and personal property so financed as
security for such payment.

     Municipal Notes generally are used to provide for short-term  capital needs
and generally have maturities of one year or less. Municipal Notes include:

     1. TAX ANTICIPATION  NOTES.  Tax  Anticipation  Notes are issued to finance
working  capital  needs  of  municipalities.   Generally,  they  are  issued  in
anticipation of various tax revenues,  such as income,  sales,  use and business
taxes, and are payable from these specific future taxes.

                                       2
<PAGE>

     2. REVENUE  ANTICIPATION  NOTES.  Revenue  Anticipation Notes are issued in
expectation  of  receipt of other  kinds of  revenue,  such as federal  revenues
available under the Federal Revenue Sharing Programs.

     3. BOND ANTICIPATION  NOTES. Bond Anticipation  Notes are issued to provide
interim financing until long-term financing can be arranged.  In most cases, the
long-term bonds then provide the money for the repayment of the Notes.

     4.  CONSTRUCTION  LOAN NOTES.  Construction  Loan Notes are sold to provide
construction financing.  Permanent financing,  the proceeds of which are applied
to the payment of Construction Loan Notes, is sometimes provided by a commitment
by the Government  National Mortgage  Association  ("GNMA") to purchase the loan
notes,  accompanied  by a commitment by the Federal  Housing  Administration  to
insure mortgage advances thereunder. In other instances,  permanent financing is
provided by commitments of banks to purchase the loan notes.

     Issues  of  Municipal  COMMERCIAL  PAPER  typically  represent  short-term,
unsecured, negotiable promissory notes. These obligations are issued by agencies
of state and local  governments  to finance  seasonal  working  capital needs of
municipalities  or to provide interim  construction  financing and are paid from
general  revenues of  municipalities  or are refinanced  with long-term debt. In
most cases,  Municipal Commercial Paper is backed by letters of credit,  lending
agreements,  note  repurchase  agreements  or other credit  facility  agreements
offered by banks or other institutions.

WHEN-ISSUED  SECURITIES.  Each Series may  purchase  municipal  securities  on a
when-issued  basis, in which case delivery and payment normally take place 15 to
45 days after the date of the commitment to purchase. The payment obligation and
the interest  rate that will be received on the  municipal  securities  are each
fixed at the time the buyer enters into the  commitment.  Although a Series will
only purchase a municipal  security 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.

     Municipal  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
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 a Series'  assets will vary.  Purchasing a
municipal  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  Series  consisting  of cash or  liquid  debt
securities  equal  to  the  amount  of  the  when-issued   commitments  will  be
established with the Custodian and marked to market daily,  with additional cash
or liquid debt securities  added when necessary.  When the time comes to pay for
when-issued  securities,  the Series will meet their respective obligations from
then available cash, sale of securities  held in the separate  account,  sale of
other  securities or,  although they would not normally expect to do so, sale of
the when-issued  securities themselves (which may have a value greater or lesser
than  the  Series'  payment  obligations).  Sale  of  securities  to  meet  such
obligations  carries with it a potential  for the  realization  of capital gain,
which is not exempt from federal or California income taxes.

FLOATING RATE AND VARIABLE RATE  SECURITIES.  Each Series may purchase  floating
rate and variable rate securities,  including  participation  interests therein.
Investments  in floating or  variable  rate  securities  normally  will  involve
industrial  development or revenue bonds which provide that the rate of interest
is set as a specific  percentage  of a  designated  base rate,  such as rates on
Treasury Bonds or Bills or the prime rate at a major commercial bank, and that a
Series can demand payment of the obligations on short notice at par plus accrued
interest,  which  amount may be more or less than the  amount a Series  paid for
them.  Variable rate securities provide for a specified  periodic  adjustment in
the interest rate,  while floating rate  securities  have an interest rate which
changes  whenever  there is a  change  in the  designated  base  interest  rate.
Frequently  such  securities  are  secured by letters of credit or other  credit
support  arrangements  provided by banks. The quality of the underlying creditor
or of the bank,  as the case may be, must be  equivalent  to the  standards  set
forth with respect to taxable investments listed below.

STAND-BY  COMMITMENTS.  The Series may acquire stand-by commitments with respect
to  securities  they  hold.  These   commitments  would  obligate  a  dealer  to
repurchase, at the Series' option, specified securities at a specified price.

                                       3
<PAGE>

     The price which a Series would pay for municipal  securities  with stand-by
commitments  generally  would be higher than the price which  otherwise would be
paid for the municipal securities alone. A Series would use stand-by commitments
for liquidity  purposes in order to permit it to remain more fully invested than
would  otherwise  be the case by  providing  a ready  market for  certain of its
portfolio  securities at an acceptable price. The stand-by commitment  generally
is for a shorter term than the maturity of the security and does not restrict in
any way the Series' right to dispose of or retain the security.  There is a risk
that the seller may not be able to repurchase  the security upon the exercise of
the right to resell by the Series.  To minimize such risks,  a Series would only
purchase  obligations  with stand-by  commitments from sellers the Manager deems
creditworthy.

TAXABLE INVESTMENTS. Under normal market conditions, each Series will attempt to
invest  100% and as a matter of  fundamental  policy will invest at least 80% of
the value of its net assets in  securities  the interest on which is exempt from
regular  federal income tax and California  personal  income tax. Such interest,
however,  may be subject to the  federal  alternative  minimum  tax. In abnormal
market conditions,  if, in the judgment of the Manager, the municipal securities
satisfying the Series' investment objectives may not be purchased, a Series may,
for defensive purposes,  temporarily invest in instruments the interest on which
is exempt from regular federal income taxes, but not California  personal income
taxes. Such securities would include those described under "California Municipal
Securities" above that would otherwise meet the Series' objectives.

     Also,  in abnormal  market  conditions,  a Series may invest on a temporary
basis in fixed-income  securities,  the interest on which is subject to federal,
state or local income taxes, pending the investment or reinvestment in municipal
securities of proceeds of sales of shares or sales of portfolio  securities,  in
order to avoid  the  necessity  of  liquidating  portfolio  investments  to meet
redemptions  of shares by  investors or where  market  conditions  due to rising
interest  rates  or  other  adverse  factors  warrant  temporary  investing  for
defensive  purposes.  Investments in taxable securities will be substantially in
securities  issued or guaranteed by the United States Government (such as bills,
notes and bonds), its agencies,  instrumentalities or authorities;  highly-rated
corporate  debt  securities   (rated  AA-,  or  better,  by  Standard  &  Poor's
Corporation  ("S&P") or Aa3,  or  better,  by Moody's  Investors  Service,  Inc.
("Moody's"));  prime commercial paper (rated A-1+/A-1 by S&P or P-1 by Moody's);
and certificates of deposit of the 100 largest domestic banks in terms of assets
which are subject to  regulatory  supervision  by the U.S.  Government  or state
governments and the 50 largest foreign banks in terms of assets with branches or
agencies in the United States. Investments in certificates of deposit of foreign
banks and foreign  branches of U.S. banks may involve  certain risks,  including
different regulation, use of different accounting procedures, political or other
economic developments, exchange controls, or possible seizure or nationalization
of foreign deposits.

     Such temporary  investments in federal but not state  municipal  securities
and fully taxable  securities will be limited as a matter of fundamental  policy
to 20% of the value of a Series' net assets under normal market conditions.

PORTFOLIO  TURNOVER.  Portfolio  transactions will be undertaken  principally to
accomplish  a Series'  objective  in relation to  anticipated  movements  in the
general  level of  interest  rates but a Series  may also  engage in  short-term
trading consistent with its objective. Securities may be sold in anticipation of
a market decline (a rise in interest  rates) or purchased in  anticipation  of a
market  rise (a decline  in  interest  rates) and later  sold.  In  addition,  a
security  may be sold and another  purchased at  approximately  the same time to
take advantage of what the Manager  believes to be a temporary  disparity in the
normal yield relationship between the two securities.

   
     The  Series'   investment   policies  may  lead  to  frequent   changes  in
investments,  particularly in periods of rapidly  fluctuating  interest rates. A
change in securities  held by a Series is known as "portfolio  turnover" and may
involve the payment by the Series of dealer spreads or underwriting commissions,
and  other  transaction  costs,  on the  sale of  securities,  as well as on the
reinvestment of the proceeds in other securities.  Portfolio turnover rate for a
fiscal  year is the  ratio of the  lesser  of  purchases  or sales of  portfolio
securities  to  the  monthly  average  of the  value  of  portfolio  securities.
Securities whose maturity or expiration date at the time of acquisition were one
year or less are excluded from the calculation. The portfolio turnover rates for
the  High-Yield  Series for the fiscal years ended  September  30, 1997 and 1996
were  22.42% and  34.75%,  respectively.  For the same  periods,  the  portfolio
turnover  rates for the Quality Series were 12.16% and 12.84%,  respectively.  A
Series'  portfolio  turnover rate will not be a limiting factor when such Series
deems it desirable to sell or purchase securities.

                             INVESTMENT LIMITATIONS

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

- -   Borrow  money,  except from banks for  temporary  purposes  (such as meeting
    redemption  requests or for extraordinary or emergency  purposes but not for
    the purchase of portfolio  securities) in an amount not to exceed 10% of the
    value of its total assets at the time the  borrowing is made (not  including
    the  amount  borrowed).  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 secure permitted borrowings
    noted above;

- -   Invest more than 25% of total  assets at market  value in any one  industry;
    except that municipal securities and securities of the U.S. Government,  its
    agencies and  instrumentalities  are not considered an industry for purposes
    of this limitation;

- -   As to 50% of the  value of its  total  assets,  purchase  securities  of any
    issuer if  immediately  thereafter  more  than 5% of total  assets at market
    value would be invested in the  securities  of any issuer  (except that this
    limitation  does  not  apply  to  obligations  issued  or  guaranteed  as to
    principal   and  interest  by  the  U.S.   Government  or  its  agencies  or
    instrumentalities);

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

- -   Purchase  or hold any real  estate,  except  that the  Series  may invest in
    securities  secured by real estate or interests therein or issued by persons
    (other  than real  estate  investment  trusts)  which deal in real estate or
    interests therein;

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

- -   Write or purchase put, call, straddle or spread options; purchase securities
    on margin or sell "short";  or underwrite  the  securities of other issuers,
    except that the Series may be deemed an underwriter  in connection  with the
    purchase and sale of portfolio securities;

- -   Purchase  or sell  commodities  or  commodity  contracts  including  futures
    contracts; or

- -   Make loans,  except to the extent that the purchase of notes, bonds or other
    evidences of indebtedness or deposits with banks may be considered loans.

     As a matter of policy,  with respect to 75% of a Series' assets, no revenue
bond  will be  purchased  if as a result of such  purchase  more than 5% of such
Series'  assets would be invested in the  securities  of a single  issuer.  This
policy is not fundamental and may be changed by the Trustees without shareholder
approval.

     Under  the  1940  Act,  a "vote of a  majority  of the  outstanding  voting
securities"  of a 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.

     per meeting fee for  Trustees was  increased by $1,000,  which is allocated
     among all Funds in the Fund Complex.

(2)  As defined in the  Prospectus,  the Seligman Group of Investment  Companies

 (d) Deferred.

     The Trust has a compensation  arrangement  under which outside trustees may
elect to defer receiving their fees. Under this arrangement, interest is accrued
on the deferred balances.  The annual cost of such fees and interest is included
in the

                                       9
<PAGE>

   
Trustees' fees and expenses,  and the accumulated balance thereof is included in
"Liabilities" in the Trust's financial statements.  The total amount of deferred
compensation (including interest) payable in respect of the Trust to Mr. Whitson
as of September 30, 1997 was $13,448.  Messrs.  Merow and Pitney no longer defer
current  compensation;  however,  they have accrued deferred compensation in the
amounts of $39,026 and $28,133 as of September  30,  1997.  The Fund has applied
for and received  exemptive  relief that would permit a director who has elected
deferral  of his or her fees to choose a rate of return  equal to either (i) the
interest rate on short-term  Treasury  bills,  or (ii) the rate of return on the
shares of any of the investment  companies advised by the manager, as designated
by the director.  The Fund may, but is not obligated to, purchase shares of such
investment  companies to hedge its  obligations in connection with this deferral
arrangement.
    

     Trustees  and  officers  of the  Trust  are also  trustees,  directors  and
officers of some or all of the other investment companies in the Seligman Group.

   
     The Trustees and officers of the Trust as a group owned less than 1% of the
Class A shares of the  High-Yield  Series at  January 2, 1998.  No  Trustees  or
officers  owned any Class A shares  of the  Quality  Series or Class D shares of
either Series at that date.
    

                             MANAGEMENT AND EXPENSES

   
     Under the Management  Agreements,  each dated December 29, 1988, subject to
the control of the Trustees, the Manager manages the investment of the assets of
each  Series,  including  making  purchases  and sales of  portfolio  securities
consistent with the Series' investment objectives and policies,  and administers
its business and other affairs.  The Manager provides the Trust with such office
space,  administrative  and other services and executive and other  personnel as
are necessary for Trust operations.  The Manager pays all of the compensation of
Trustees of the Trust who are  employees or  consultants  of the Manager and the
officers and employees of the Trust. The Manager also provides senior management
for Seligman Data Corp., the Trust's  shareholder  service agent. The Manager is
entitled to receive a management  fee from each of the Series  calculated  daily
and payable  monthly equal to 0.50% of each Series'  average daily net assets on
an annual  basis.  The chart below  indicates the  management  fees paid by each
Series as well as the percentage such fee represents of each Series'  respective
average daily net assets for the fiscal years ended September 30, 1997, 1996 and
1995.

     The Trust pays all its  expenses  other than those  assumed by the  Manager
including  brokerage  commissions,  if any,  fees and  expenses  of  independent
attorneys and auditors,  taxes and governmental fees including fees and expenses
of qualifying the Trust 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 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 and  expenses of  Trustees of the Trust not  employed by or
serving as a Trustee of the Manager or its  affiliates,  insurance  premiums and
extraordinary  expenses such as litigation  expenses.  The Trust's  expenses are
allocated  between the Series in a manner  determined by the Trustees to be fair
and equitable.

     Each Series' Management  Agreement was unanimously approved by the Trustees
at a Meeting  held on October 11, 1988 and was approved by the  shareholders  of
each Series at a meeting held on December 15, 1988.  Each  Management  Agreement
will continue in effect until  December 31 of each year if (1) such  continuance
is  approved  in the  manner  required  by the  1940 

                                       10
<PAGE>

Act (i.e., by a vote of a majority of the Trustees or of the outstanding  voting
securities of the 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 the Series at least 60 days prior to
the anniversary  date of the previous  continuance  that it does not desire such
continuance.  A Management  Agreement  may be  terminated  by a 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 Appendix
B 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  Compliance  Officer,  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
Compliance  Officer,  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 PLAN

     An Administration,  Shareholder Services and Distribution Plan (the "Plan")
for the Series is in effect under  Section  12(b) of the 1940 Act and Rule 12b-1
thereunder.

     The Plan  was  approved  on July  16,  1992 by the  Trustees,  including  a
majority of the  Trustees  who are not  "interested  persons" (as defined in the
1940 Act) of the Trust and who have no direct or indirect  financial interest in
the  operation  of the  Plan  or in any  agreement  related  to  the  Plan  (the
"Qualified  Trustees")  and was  approved  by  shareholders  of each Series at a
Special  Meeting of  Shareholders  held on November  23,  1992.  The Plan became
effective on January 1, 1993 and 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 Trust,  cast in person at a
meeting  called for the purpose of voting on such  approval.  Amendments  to the
Plan were  approved in respect of the Class D shares on November 18, 1993 by the
Trustees,  including a majority of the Qualified Trustees,  and became effective
with  respect to the Class D shares on  February  1,  1994.  The Plan may not be
amended to  increase  materially  the amounts  payable to Service  Organizations
without the approval of a majority of the outstanding  voting  securities of the
Series and no material amendment to the Plan may be made except by a majority of
both the Trustees and Qualified Trustees.

                                       11
<PAGE>

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

                             PORTFOLIO TRANSACTIONS

   
     No brokerage commissions were paid by either Series during the fiscal years
ended  September 30, 1997, 1996 or 1995. When two or more Series of the Trust or
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 already obtainable or saleable.
    

                    PURCHASE AND REDEMPTION OF SERIES SHARES

     The High-Yield Series and Quality Series each issues two classes of shares:
Class A shares may be  purchased  at a price  equal to the next  determined  net
asset value per share,  plus a 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 of 1% if such shares are redeemed  within eighteen months 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 certain
redemptions within one year of purchase. See "Alternative  Distribution System,"
"Purchase of Shares," and "Redemption of Shares" in the Series' Prospectus.

SPECIMEN PRICE MAKE-UP

   
     Under  the  current  distribution  arrangements  between  the Trust and the
Distributor,  Class A shares are sold at a maximum sales load of 4.75% and Class
D shares are sold at net asset  value.*  Using each  Series'  net asset value at

*    Class D shares are subject to a CDSL of 1% on  redemptions  within one year
     of purchase. Class A shares purchased at net asset value due to the size of
     the purchase  are subject to a CDSL of 1% on  redemptions  within  eighteen
     months of  purchase  of such  shares.  See  "Redemption  of  Shares" in the
     Prospectus.
    

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 the High-Yield  Series and Quality  Series alone,  the other series of
the Trust 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 the Prospectuses.

   
     THE RIGHT OF  ACCUMULATION  allows an investor to combine the amount  being
invested in Class A shares of High-Yield  Series and Quality  Series,  the other
series of the  Trust and  shares of other  Seligman  Mutual  Funds  sold with an
initial  sales  load with the total  net asset  value of shares of those  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 Seligman Mutual Fund on which there was
an initial  sales load at the time of purchase to determine  reduced sales loads
in  accordance  with the schedule in the  Prospectuses.  The value of the shares
owned,  including the value of shares of Seligman Cash  Management Fund acquired
in an  exchange of shares of another  Seligman  Mutual Fund on which there 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 at the time
a  purchase  is  made  and  is  furnished   sufficient   information  to  permit
confirmation.

     A LETTER OF INTENT  allows an investor  to  purchase  Class A shares of the
High-Yield  Series and Quality Series over a 13-month  period at reduced initial
sales loads in accordance  with the schedule in the  Prospectuses,  based on the
total amount of Class A shares 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  series of the Trust and other  Seligman  Mutual  Funds
already  owned  and the  total  net  asset  value of  shares  of  Seligman  Cash
Management  Fund which were  acquired  through an  exchange of shares of another
Seligman  Mutual  Fund on which  there was an initial  sales load at the time of
purchase.  Reduced initial 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" in the Prospectus.
    

     Class A shares  purchased  without an initial sales load in accordance with
the sales load  schedule in the  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 sales loads apply to purchases of
Class A shares of each 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 (the "Code"),  tax-exempt  organizations  under Section 501 (c)(3) or
(13) of the Code, and non-qualified  employee benefit plans that satisfy uniform
criteria are considered "single persons" for this purpose.  The uniform criteria
are as follows:

1.  Employees  must  authorize  the  employer,  if requested by the Series',  to
    receive in bulk and to distribute to each  participant on a timely basis the
    Series' 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 Series 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 the  Prospectus
applies  to sales to  "eligible  employee  benefit  plans"  (as  defined  in the
Prospectus),  except  that each  Series  may sell  shares at net asset  value to
"eligible  employee benefit plans," which have at least (i) $500,000 invested in
the  Seligman  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 funding or other systems  acceptable to Seligman Data Corp.,  the
Trust'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.

   
FURTHER TYPES OF REDUCTIONS. Class A shares of each Series 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 financial
institution trust  departments,  to registered  investment  advisers  exercising
investment  discretionary  authority  with  respect  to the  purchase  of Series
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  Series,  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 financial  institution  trust
departments;   to  registered   investment  advisers  exercising   discretionary
investment authority with respect to the purchase of Fund 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 Fund;
to  other  investment  companies  in the  Seligman  Group in  connection  with a
deferred  fee  arrangement  for outside  directors;  and to  "eligible  employee
benefit plans" which have at least (i) $500,000  invested in the Seligman 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 Fund shares.  Sales of shares
to such plans must be made in connection with a payroll deduction system of plan
funding or other system acceptable to Seligman Data Corp.
    

    Class A shares of the  High-Yield  Series and Quality  Series may be sold at
net asset value to present and retired Trustees, directors,  officers, employees
(and  family  members,  as defined in the  Prospectus)  of the Trust,  the other
investment  companies in the  Seligman  Group,  the Manager and other  companies
affiliated  with the  Manager.  Such sales also may be made to employee  benefit
plans for such persons and to any investment advisory, custodial, trust or other
fiduciary  account  managed or advised by the  Manager or any  affiliate.  These
sales may be made for investment purposes only, and shares may be resold only to
the Series.

    Class A  shares  of the  Series'  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.

PAYMENT IN SECURITIES. In addition to cash, each Series may accept securities in
payment  for  Series  shares  sold  at the  applicable  public  offering  price.
Generally,  a Series will only consider accepting securities (1) to increase its
holdings in a portfolio security of the Series, or (2) if the Manager determines
that the offered securities are a suitable investment in a sufficient amount for
efficient management.  Although no minimum has been established,  it is expected
that each Series would not accept  securities with a value of less than $100,000
per issue in payment for shares.  A Series may reject in whole or in part offers
to pay for shares  with  securities,  may  require  partial  payment in cash for
applicable sales loads, and may discontinue  accepting securities as payment for
shares at any time  without  notice.  The Series  have no present  intention  of
accepting securities in payment for shares.

MORE ABOUT  REDEMPTIONS.  The  procedures  for  redemption of the Series' shares
under ordinary circumstances are set forth in the Prospectus. Whether shares are
redeemed pursuant to the Regular or the Expedited  Redemption Service (less than
$1,000), a check for the proceeds  ordinarily will be sent within seven calendar
days following redemption.  Payment may be made in securities,  or postponed, if
the orderly liquidation of portfolio  securities is prevented by the closing of,
or  restricted  trading  on,  the New York  Stock  Exchange,  during  periods of
emergency,  or during  such  other  periods as  ordered  by the  Securities  and
Exchange  Commission.  If payment  were to be made in  securities,  shareholders
receiving  securities could incur certain  transaction costs. The Trust will not
accept orders from securities dealers for the repurchase of shares.

                              DISTRIBUTION SERVICES

    SFSI, an affiliate of the Manager, acts as general distributor of the shares
of the Trust and of the other  mutual funds in the  Seligman  Group.  As general
distributor  of  the  Trust's  shares  of  beneficial   interest,   SFSI  allows
commissions  to all dealers of up to 4.25% on purchases of Class A shares of the
Series to which the 4.75% sales load applies. SFSI receives the balance of sales
loads and any CDSL, if  applicable,  paid by  investors.  The Trust and SFSI are
parties to a Distributing Agreement dated January 1, 1993.

   
    The total sales loads paid by shareholders of the High-Yield  Series and the
Quality Series for the fiscal year ended September 30, 1997 amounted to $146,934
and  $55,181,   respectively,   with  an  allowance  of  $129,666  and  $48,253,
respectively, as commissions to dealers; for the fiscal year ended September 30,
1996 amounted to $114,640 and $118,847, respectively, with allowance of $100,612
and $104,653,  respectively,  as commissions to dealers; and for the fiscal year
ended September 30, 1995 amounted to $103,824 and $136,990,  respectively,  with
allowance of $91,517 and $120,277,  respectively, as commissions to dealers. For
the fiscal years ended  September  30, 1997,  1996 and 1995,  SFSI retained CDSL
charges of $1,363, $443 and $288,  respectively,  for the High-Yield Series. For
the years ended September 30, 1997, 1996 and 1995, SFSI retained CDSL charges of
$1,420, $526 and $399, respectively, for the Quality Series.

    Effective April 1, 1995,  Seligman Services,  Inc. ("SSI"),  an affiliate of
the Manager, became eligible to receive commissions from certain sales of shares
of the Series,  as well as  distribution  and service fees pursuant to the Plan.
For the year ended  September 30, 1997,  SSI received  commissions  of $495 from
sales of the High-Yield Series and $1,571 from sales of the Quality Series.  SSI
also  received  distribution  and  service  fees of $1,414  with  respect to the
High-Yield  Series and $2,688 with respect to the Quality  Series.  For the year
ended  September  30, 1996,  SSI received  commissions  of $28 from sales of the
High-Yield Series and $2,241 from sales of the Quality Series. SSI also received
distribution  and services fees of $1,592 with respect to the High-Yield  Series
and $2,753 with respect to the Quality  Series.  For the period ended  September
30, 1995, SSI received  commissions of $218 from sales of the High-Yield  Series
and $282 from sales of the Quality Series.  SSI also received  distribution  and
service  fees of $465 with  respect to the  High-Yield  Series  and $1,141  with
respect to the Quality Series.
    

                                      TAXES

   
    Under the Code,  each  Series of the Trust  will be  treated  as a  separate
corporation for federal income tax purposes. As a result,  determinations of net
investment  income,  exempt-interest  dividends and net long-term and short-term
capital gain and loss will be made separately for each Series.

    Each  Series  intends  to qualify  and elect to be  treated  as a  regulated
investment  company under the Code and thus to be relieved of federal income tax
on amounts  distributed to  shareholders;  provided that it distributes at least
90% of its net investment income and net short-term capital gains, if any.

    Qualification  as a regulated  investment  company  under the Code  requires
among  other  things,  that (a) at least 90% of the annual  gross  income of the
Series be derived from dividends,  interest, payments with respect to securities
loans and gains from the sale or other  disposition  of stocks or  securities or
foreign  currencies,  or other income  (including  but not limited to gains from
options, futures, and forward contracts) derived with respect to its business of
investing  in  such  stocks,  securities  or  currencies;  and  (b)  the  Series
diversifies  its  holdings  so that,  at the end of each  quarter of the taxable
year,  (i) at least 50% of the market value of the Series assets is  represented
by cash,  United States  Government  securities and other securities  limited in
respect of any one issuer to an amount not greater than 5% of the Series  assets
and 10% of the outstanding  voting securities of such issuer,  and (ii) not more
than 25% of the value of its assets is  invested  in the  securities  of any one
issuer (other than U.S. Government securities).
    

                                    VALUATION

   
    The net asset value per share of each class of a Series Trust is  determined
as of the close of  regular  trading  on the New York  Stock  Exchange  ("NYSE")
(normally, 4:00 p.m. Eastern time), on each day that the NYSE is open. The Trust
and the NYSE are currently  closed on New Year's Day,  Martin  Luther King,  Jr.
Day,  Presidents' Day, Good Friday,  Memorial Day,  Independence Day, Labor Day,
Thanksgiving  Day and  Christmas  Day. The Trust will also  determine  net asset
value for each
    

                                       15
<PAGE>

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 D shares of a Series
will  generally  be lower  than the net  asset  value of Class A shares  of such
Series  as a result  of the  higher  distribution  fee with  respect  to Class D
shares. It is expected,  however,  that the net asset value per share of the two
classes will tend to converge  immediately  after the  recording  of  dividends,
which will  differ by  approximately  the amount of the  distribution  and other
class expenses accrual differential between the classes.

    The  High-Yield and Quality  Series  municipal  securities are valued on the
basis of quotations provided by an independent pricing service,  approved by the
Trustees,  which  uses  information  with  respect  to  transactions  in  bonds,
quotations from bond dealers,  market transactions in comparable  securities and
various relationships between securities in determining value. In the absence of
such quotations,  in accordance with fair value as determined in accordance with
procedures   approved  by  the  Trustees.   Short-term  notes  having  remaining
maturities of 60 days or less are generally valued at amortized cost.

    Generally,  trading  in certain  securities  such as  municipal  securities,
corporate bonds, U.S.  Government  securities,  and money market  instruments is
substantially  completed  each day at  various  times  prior to the close of the
NYSE. The values of such securities used in determining the net asset value of a
Series' shares are computed as of such times. Occasionally, events affecting the
value of such  securities may occur between such times and the close of the NYSE
which will not be reflected in the  computation of a Series' net asset value. If
events  materially  affecting  the value of such  securities  occur  during such
period,  then these  securities  and other  assets  will be valued at their fair
market value as determined in good faith by the Trustees.

                             PERFORMANCE INFORMATION

   
    The annualized yield for the Class A shares of the High-Yield Series and the
Quality  Series for the 30-day  period  ended  September  30, 1997 was 4.15% and
4.08%,  respectively.  The annualized yield was computed by dividing the 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 September 30, 1997,  which was the last
day of this  period.  The  average  number of Class A shares  of the  High-Yield
Series and Quality Series was 7,970,961 and 12,644,829,  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 the
Prospectus.

    The  tax  equivalent  annualized  yields  for  the  Class  A  shares  of the
High-Yield  Series and the Quality Series for the 30-day period ended  September
30, 1997 were 7.57% and 7.44%, respectively. The tax equivalent annualized yield
was computed by first computing the annualized  yield as discussed  above.  Then
the  portion of the yield  attributable  to  securities  the income of which was
exempt for federal and state income tax purposes was determined. This portion of
the yield was then divided by one minus 45.22% (45.22% being the assumed maximum
combined  federal and state income tax rate for  individual  taxpayers  that are
subject to  California  personal  income  taxes).  Then the small portion of the
yield attributable to securities the income of which was exempt only for federal
income tax purposes was  determined.  This portion of the yield was then divided
by one minus 39.6% (39.6% being the maximum federal income tax rate).  These two
calculations  were then added to the portion of the yield,  if any, that was not
attributable to securities, the income of which was NOT tax exempt.

    The average annual total returns for the one-year period ended September 30,
1997 for the Class A shares of the High-Yield Series and the Quality Series were
3.64% and 3.66%, respectively; for the five-year period ended September 30, 1997
were 5.94% and 5.79%, respectively;  and for the ten-year period ended September
30, 1997 were 8.06% and 8.07%,  respectively.  These  returns  were  computed by
assuming a hypothetical initial payment of $1,000. From this $1,000, the maximum
sales load of $47.50 (4.75% of public offering price) was deducted.  It was then
assumed that all of the  dividends and  distributions  paid by a Series over the
relevant time period were reinvested. It was then assumed that at the end of the
one-year period,  five-year period and ten-year period of the Series, the entire
amount was redeemed. The average annual
    

                                       16
<PAGE>

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 annualized  yields for the 30-day period ended September 30, 1997 or the
Class D shares of the High-Yield Series and Quality Series were 3.47% and 3.40%,
respectively.  The  annualized  yield was  computed  by  dividing a Series'  net
investment  income per share  earned  during this  30-day  period by the maximum
offering  price per share (i.e.,  the net asset  value) on  September  30, 1997,
which  was the last day of this  period.  The  average  number of Class D shares
were: High-Yield-499,114, and Quality-282,802 which was the average daily number
of shares  outstanding  during the 30-day  period that were  eligible to receive
dividends.

    The tax equivalent  annualized  yields for the 30-day period ended September
30, 1997 for the Class D shares of the High-Yield Series and Quality Series were
6.33% and 6.20%, respectively.  The tax equivalent annualized yield was computed
as discussed above for Class A shares.

    The average  annual total  returns for the Class D shares of the  High-Yield
Series and the Quality Series for the one-year  period ended  September 30, 1997
were 6.60% and 6.75%, respectively, and since inception through the period ended
September  30,  1997 were  4.95% and 3.98%,  respectively.  These  returns  were
computed by assuming a hypothetical  initial payment of $1,000 in Class D shares
of each Series and that all of the  dividends and  distributions  by the Series'
Class D shares  over the  relevant  time  period  were  reinvested.  It was then
assumed  that  at the  end of each  period,  the  entire  amount  was  redeemed,
subtracting the 1% CDSL, if applicable .

    The tables below  illustrate  the total  returns on a $1,000  investment  in
Class A shares of each of the Series for the ten years ended September 30, 1997,
and in the  Class D  shares  of each of the  Series  from  the  commencement  of
operations through September 30, 1997,  assuming investment of all dividends and
capital gain distributions.

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

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 or CDSL, if applicable; 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;  and finally,  by dividing
    the difference between the amount of the hypothetical  initial investment at
    the  beginning  of the  period and its value at the end of the period by the
    amount of the hypothetical initial investment.

     A Series' Class A total return and average  annual total return quoted does
not  reflect the  deduction  of the  administration,  shareholder  services  and
distribution  fee for period  prior to January 1, 1993,  which fee if  reflected
would reduce the performance quoted.

                               GENERAL INFORMATION

     The Trustees are  authorized to classify or reclassify and issue any shares
of  beneficial  interest of the Trust into any number of other  classes  without
further action by  shareholders.  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.

     As a general  matter,  the Trust 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 Trust or any series, including the Fund, 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 Trust 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 Code, 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 Trust or the  shareholders,  and (f) with
respect to such additional  matters  relating to the Trust as may be required by
the  1940  Act,  the  Declaration  of  Trust,  the  By-laws  of the  Trust,  any
registration  of the Trust 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 Trust have the  right,  upon the  declaration  in
writing or vote of more than two-thirds of the Trust'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 Trustee  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 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  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
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  to be
submitted  by the  provisions  of the  1940  Act or  applicable  state  law,  or
otherwise,  to the holders of the outstanding voting securities of an investment
company  such as the Trust  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 each 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  public  accountants,  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.

                  SPECIAL CONSIDERATIONS REGARDING INVESTMENTS
                       IN CALIFORNIA MUNICIPAL SECURITIES

         The following  information as to certain  California  considerations is
given to  investors  in view of the  Fund's  policy of  investing  primarily  in
securities of California issuers.  Such information is derived from sources that
are  generally  available  to  investors  and is  believed  by the Manager to be
accurate. Such information constitutes only a brief summary, does not purport to
be a complete  description and is based on information from official  statements
relating to securities offerings of California issuers.

   
         California's  economy,  the largest  among the 50 states and one of the
largest in the world, has major components in agriculture,  manufacturing,  high
technology,   trade,   entertainment,   tourism,   construction   and  services.
California's  economy is  approaching  a major  milestone in 1997 as gross state
domestic  product is  expected to pass the $1  trillion  mark.  As a stand alone
economy,  California's economy would rank seventh in the world, ahead of China's
and behind the United  Kingdom.  The State's  August 1, 1996  population of 32.4
million represents over 12 percent of the total United States  population,  with
total employment over 14 million.

         From  1990-1993,  the State suffered  through a severe  recession,  the
worst   since   the   1930's,   heavily   influenced   by  large   cutbacks   in
defense/aerospace industries and military base closures and a major drop in real
estate  construction.  California's  economy  has been  recovering  and  growing
steadily  stronger  since the  start of 1994,  to the  point  where the  State's
economic  growth is outpacing the rest of the nation.  More than 300,000 nonfarm
jobs were added in the State in 1996,  while  personal  income grew by more than
$55  billion.  Another  380,000  jobs are  expected  to be created in 1997.  The
unemployment rate, while still higher than the national average, fell to the low
6% range in mid-1997, compared to over 10% at the worst of the recession.

         California's  economic  expansion is being  fueled by strong  growth in
high-technology   industries,    including   computer   software,    electronics
manufacturing and motion picture/television production; growth is also strong in
business  services,  export trade,  and  manufacturing,  with even the aerospace
sector now showing  increased  employment.  The State's economy is now much more
balanced  and  diversified  than it was during the 1980's.  Nonresidential  real
estate  construction has grown rapidly in response to the growth in the economy.
Residential  construction  has been  growing  slowly  since  the  depths  of the
recession,  but remains much lower (as measured by annual new unit permits) than
the late 1980's.
    

         The State is  subject  to an annual  appropriations  limit  imposed  by
Article  XIII B of the State  Constitution  (the  "Appropriations  Limit").  The
Appropriations Limit does not restrict appropriations to pay debt service on the
Bonds or other  voter-authorized  bonds. Article XIII B prohibits the State from
spending  "appropriations subject to limitation" in excess of the Appropriations
Limit.  "Appropriations  subject to limitation",  with respect to the State, are
authorizations to spend "proceeds of taxes", which consist of tax revenues,  and
certain other funds,  including proceeds from regulatory licenses,  user charges
or other fees to the extent that such proceeds exceed "the cost reasonably borne
by that entity in providing the regulation,  product or service",  but "proceeds
of taxes" exclude most state subventions to local  governments,  tax refunds and
some benefit  payments such as  unemployment  insurance.  No limit is imposed on
appropriations  of funds which are not  "proceeds of taxes",  such as reasonable
user charges or fees and certain other non-tax funds.

         Not included in the  Appropriations  Limit are  appropriations  for the
debt  service  costs of bonds  existing  or  authorized  by January 1, 1979,  or
subsequently  authorized by the voters,  appropriations  required to comply with
mandates  of courts or the  federal  government,  appropriations  for  qualified
capital outlay projects, appropriations of revenues derived from any increase in
gasoline taxes and motor vehicle  weight fees above January 1, 1990 levels,  and
appropriation  of certain special taxes imposed by initiative  (e.g.  cigarettes
and tobacco taxes).  The  Appropriations  Limit may also be exceeded in cases of
emergency.

         The State's Appropriations Limit in each year is based on the limit for
the prior year,  adjusted annually for changes in California per capita personal
income  and  changes in  population,  and  adjusted,  when  applicable,  for any
transfer of financial  responsibility  of providing  services to or from another
unit of government. The Appropriations Limit is tested over consecutive two-year
periods.  Any excess of the  aggregate  "proceeds of taxes"  received  over such
two-year period above the combined  Appropriations Limits for those two years is
divided equally between transfers to local school and community college ("K-14")
districts and refunds to taxpayers.

                                       20
<PAGE>

         The  Legislature  has enacted  legislation to implement  Article XIII B
which  defines  certain  terms used in Article XIII B and sets forth the methods
for determining the Appropriations Limit.  Government Code Section 7912 requires
an estimate of the Appropriations Limit to be included in the Governor's Budget,
and thereafter to be subject to the budget process and established in the Budget
Act.

   
         For the 1996-1997 Fiscal Year, the State  Appropriations  Limit and the
Appropriations  Subject to Limit were  estimated to be $42.0 and $35.3  billion,
respectively,  resulting  in an amount  under the  limit of  approximately  $6.7
billion.  For the  1997-1998  Fiscal Year,  the State  Appropriations  Limit and
Appropriations  Subject to Limit are  estimated  to be $44.8 and $38.0  billion,
respectively,  resulting  in an amount  under the  limit of  approximately  $6.8
billion.
    

PROPOSITION 98

   
         On November 8, 1988,  voters of the State  approved  Proposition  98, a
combined initiative  constitutional  amendment and statute called the "Classroom
Instructional  Improvement and Accountability Act".  Proposition 98 (as modified
by Proposition 111, which was enacted on June 5, 1990), changed State funding of
public  education  below the  university  level,  and the operation of the State
Appropriations Limit,  primarily by guaranteeing K-14 schools a minimum share of
General Fund  revenues.  Proposition 98 permits the  Legislature,  by two-thirds
vote of both  houses and with the  Governor's  concurrence,  to suspend the K-14
schools'  minimum  funding  formula for a one-year  period.  Proposition 98 also
contains  provisions  transferring  certain  State tax revenues in excess of the
Article XIII B limit to K-14 schools.  The 1997-1998 Budget Act contains a large
increase in funding for K-14 education under  Proposition 98,  reflecting strong
revenues which have exceeded initial budgeted amounts.  Part of the nearly $1.75
billion increased spending is allocated to prior fiscal years.
    


FISCAL YEARS PRIOR TO 1995-96

   
         Pressures  on the State's  budget in the late  1980's and early  1990's
were caused by a combination of external  economic  conditions and growth of the
largest   General   Fund   Programs--K-14   education,   health,   welfare   and
corrections--at  rates  faster  than the revenue  base.  These  pressures  could
continue as the State's overall population and school age population continue to
grow, and as the State's  corrections  program responds to a "Three Strikes" law
enacted  in 1994,  which  requires  mandatory  life  prison  terms  for  certain
third-time  felony  offenders.  In  addition,  the  State's  health and  welfare
programs  are in a  transition  period as a result of recent  federal  and State
welfare reform initiatives.

         As a result of these  factors  and  others,  and  especially  because a
severe recession between  1990-1994 reduced revenues and increased  expenditures
for social welfare programs, from the late 1980's until 1992-93, the State had a
period of budget imbalance.  During this period,  expenditures exceeded revenues
in four out of six  years,  and the State  accumulated  and  sustained  a budget
deficit in its reserve  the Special  Fund for  Economic  Uncertainties  ("SFEU")
approaching  $2.8  billion at its peak at June 30,  1993.  Between  1991-92  and
1994-95 Fiscal Years, each budget required  multibillion dollar actions to bring
projected revenues and expenditures into balance,  including significant cuts in
health and welfare program expenditures;  transfers of program  responsibilities
and  funding  from  the  State  to  local  governments;   transfers  of  program
responsibilities  and funding from State to local  governments;  transfers of or
about  $3.6  billion in annual  local  property  tax  revenues  to local  school
districts,  thereby reducing State funding for schools under Proposition 98; and
revenue increases (particularly in the 1991-92 Fiscal Year budget),most of which
were for a short duration.
    

         Despite these budget  actions,  as noted,  the effects of the recession
led to large,  unanticipated  deficits  in the  budget  reserve,  the  SFEU,  as
compared to  projected  positive  balances.  By the  1993-94  Fiscal  Year,  the
accumulated  deficit was so large that it was impractical to budget to retire it
in one year,  so a two-year  program  was  implemented,  using the  issuance  of
revenue anticipation  warrants to carry a portion of the deficit over the end of
the fiscal year. When the economy failed to recover  sufficiently in 1993-94,  a
second two-year plan was implemented in 1994-95,  again using  cross-fiscal year
revenue  anticipation  warrants to partly  finance the deficit  into the 1995-96
fiscal year.

         Another  consequence of the accumulated budget deficits,  together with
other factors such as disbursement of funds to local school districts "borrowed"
from  future  fiscal  years and hence not  shown in the  annual  budget,  was to
significantly  reduce the State's  cash  resources  available to pay its ongoing
obligations.  When the Legislature and the Governor failed to adopt a budget for
the 1992-93  Fiscal Year by July 1, 1992,  which would have allowed the State to
carry out its normal 

                                       21
<PAGE>

annual cash flow borrowing to replenish its cash reserves,  the State Controller
issued registered  warrants to pay a variety of obligations  representing  prior
years' or continuing  appropriations,  and mandates from court orders. Available
funds were used to make constitutionally-mandated payments, such as debt service
on bonds and warrants. Between July 1 and September 4, 1992, when the budget was
adopted,  the State Controller  issued a total of approximately  $3.8 billion of
registered warrants.

   
         For several fiscal years during the recession,  the State was forced to
rely  increasingly  on  external  debt  markets  to meet  its cash  needs,  as a
succession of notes and revenue anticipation  warrants were issued in the period
from June 1992 to July 1994,  often needed to pay  previously  maturing notes or
warrants. These borrowings were used also in part to spread out the repayment of
the  accumulated  budget  deficit  over the end of a fiscal  year.  The last and
largest of these  borrowings was $4.0 billion of revenue  anticipation  warrants
issued in July, 1994 and maturing on April 25, 1996.
    

1995-96 AND 1996-97 FISCAL YEARS

   
         With the end of the recession,  and a growing economy starting in 1994,
the State's financial  condition improved markedly in the last two fiscal years,
with a  combination  of better  than  expected  revenues,  slowdown in growth of
social welfare programs,  and continued  spending restraint based on the actions
taken in earlier years.  The last of the  recession-induced  budget deficits was
repaid,  allowing the State's  budget reserve (the SEFU) to post a positive cash
balance for only the second time in the 1990's, totaling $281 million as of June
30,  1997.  The State's  cash  position  also  returned to health,  as cash flow
borrowing  was limited to $3 billion in 1996-97,  and no deficit  borrowing  has
occurred over the end of these last two fiscal years.

         In each of these two  fiscal  years,  the State  budget  contained  the
following major features:

         1.  Expenditures  for  K-14  schools  grew  significantly,  as the  new
revenues were directed to school  spending under  Proposition 98. This new money
allowed  several  new  education  initiatives  to be  funded,  and  raised  K-12
per-pupil spending to around $4,900 by Fiscal Year 1996-97.

         2. The budgets  restrained health and welfare spending levels,  holding
to the reduced benefit levels enacted in earlier years,  and attempted to reduce
General  Fund  spending  by  calling  for  greater   support  from  the  federal
government. The State also attempted to shift to the federal government a larger
share of the cost of incarceration and social services for illegal aliens.  Some
of these efforts were successful, and federal welfare reform also helped, but as
a whole the  federal  support  never  reached  the levels  anticipated  when the
budgets were enacted.  These funding  shortfalls  were,  however,  filled by the
strong revenue collections, which exceeded expectations.

         3. General Fund support for the University of California and California
State  Universities  grew by an average of 5.2 percent and 3.3 percent per year,
respectively, and there were no increases in student fees.

         4. General  Fund  support for the  Department  of  Corrections  grew as
needed to meet increased  prison  populations.  No new prisons were approved for
construction, however.

         5. There were no tax increases, and starting January 1, 1997, there was
a 5 percent cut in corporate  taxes.  The suspension of the Renter's Tax Credit,
first taken as a cost-saving measure during the recession, was continued.

         As noted, the economy grew strongly during these fiscal years, and as a
result, the General Fund took in substantially greater tax revenues (around $2.2
billion in 1995-96 and $1.6 billion in 1996-97) than were initially planned when
the budgets were enacted. These additional funds were largely directed to school
spending as mandated by Proposition  98, and to make up shortfalls  from reduced
federal health and welfare aid. As a result, there was not any dramatic increase
in budget reserves,  although the accumulated  budget deficit from the recession
years was finally eliminated in the past fiscal year.
    

CURRENT STATE BUDGET

         THE  DISCUSSION  BELOW OF THE  1997-98  FISCAL  YEAR BUDGET IS BASED ON
ESTIMATES AND  PROJECTIONS OF REVENUES AND  EXPENDITURES  FOR THE CURRENT FISCAL
YEAR AND MUST NOT BE  CONSTRUED  AS  STATEMENTS  OF FACT.  THESE  ESTIMATES  AND
PROJECTIONS ARE

                                       22
<PAGE>
   
BASED UPON  VARIOUS  ASSUMPTIONS  WHICH MAY BE  AFFECTED  BY  NUMEROUS  FACTORS,
INCLUDING FUTURE ECONOMIC  CONDITIONS IN THE STATE AND THE NATION, AND THERE CAN
BE NO ASSURANCE THAT THE ESTIMATES WILL BE ACHIEVED.

         1997-98 FISCAL YEAR

         On January 9, 1997, the Governor  released his proposed  budget for the
1997-98  Fiscal Year (the  "Proposed  Budget").  The Proposed  Budget  estimated
General  Fund  revenues  and  transfers  of about $50.7  billion,  and  proposed
expenditures of $50.3 billion, which would leave a budget reserve in the SFEU of
about $500 million.  The Proposed Budget  included  provisions for a further 10%
cut in Bank  and  Corporate  Taxes,  which  ultimately  was not  enacted  by the
Legislature.

         At the  time  of the  May  Revision,  released  on May  14,  1997,  the
Department  of Finance  increased its revenue  estimate for the upcoming  fiscal
year by $1.3 billion,  in response to the continued strong growth in the State's
economy.  Budget negotiations continued into the summer, with major issued to be
resolved  including final  agreement on State welfare reform,  increase in State
employee salaries and consideration of a tax cut proposed by the Governor.

         In May, 1997,  action was taken by the  California  Supreme Court in an
ongoing lawsuit,  PERS v. Wilson,  which made final a judgment against the State
requiring  an immediate  payment  from the General Fund to the Public  Employees
Retirement Fund ("PERF") to make up certain  deferrals in annual retirement fund
contributions which had been legislated in earlier years for budget savings, and
which the courts found to be  unconstitutional.  On July 30,  1997,  following a
direction from the Governor,  the Controller transferred $1.235 billion from the
General  Fund to the PERF in  satisfaction  of the  judgment,  representing  the
principle amount of the improperly deferred payments from 1995-96 and 1996-97.

         FISCAL YEAR 1997-98 BUDGET ACT

         Once the pension  payment  eliminated  essentially  all the "increased"
revenue in the budget,  final  agreement  was reached  within a few weeks on the
welfare  package and the  remainder of the budget.  The  Legislature  passed the
Budget Bill on August 11, 1997,  along with numerous  related bills to implement
its  provisions.  On August 18, 1997,  the  Governor  signed the Budget Act, but
vetoed about $314 million of specific  spending  items,  primarily in health and
welfare and education areas from both the General Fund and Special Funds.

         The Budget Act anticipates General Fund revenues and transfers of $52.5
billion (a 6.8 percent increase over the final 1996-97 amount), and expenditures
of $52.8  billion  (an 8.0  percent  increase  from the  1996-97  levels).  On a
budgetary  basis,  the budget  reserve (SFEU) is projected to decrease from $408
million at June 30, 1997 to $112 million at June 30,  1998.  The Budget Act also
includes  Special  Fund  expenditures  of $14.4  billion (as  against  estimated
Special Fund revenues of $14.0 billion),  and $2.1 billion of expenditures  from
various Bond Funds. Following enactment of the Budget Act, the State implemented
its normal annual cash flow borrowing program, issuing $3 billion of notes which
mature on June 30, 1998.

         The following are major features of the 1997-98 Budget Act:

         1. For the second year in a row, the Budget  contains a large  increase
in funding for K-14 education under  Proposition 98,  reflecting strong revenues
which have exceeded initial budgeted  amounts.  Part of the nearly $1.75 billion
in increased  spending is allocated to prior fiscal years. Funds are provided to
fully pay for the  cost-of-living-increase  component of Proposition  98, and to
extend the class size reduction and reading initiatives.

         2. The Budget Act reflects  the $1.235  billion  pension case  judgment
payment,  and brings  funding of the State's  pension  contribution  back to the
quarterly  basis  which  existed  prior  to  the  deferral  actions  which  were
invalidated  by the courts.  There is no provision for any  additional  payments
relating to this court case.

         3.  Continuing  the  third  year of a  four-year  "compact"  which  the
Administration  has made with higher education  units,  funding from the General
Fund for the  University of  California  and  California  State  University  has
increased by about 6 percent ($121 million and $107 million, respectively),  and
there was no increase in student fees.

         4.  Because  of the effect of the  pension  payment,  most other  State
programs were continued at 1996-97 levels, adjusted for caseload changes.
    

                                       23
<PAGE>
   
         5. Health and welfare  costs are  contained,  continuing  generally the
grant levels from prior years, as part of the initial  implementation of the new
CalWORKs program.

         6. Unlike  prior  years,  this Budget Act does not depend on  uncertain
federal budget actions. About $300 million in federal funds, already included in
the federal FY 1997 and 1998 budgets,  are included in the Budget Act, to offset
incarceration costs for illegal aliens.

         7. The Budget Act contains no tax increases, and no tax reductions. The
Renters Tax Credit was  suspended for another year,  saving  approximately  $500
million.

         Prior to the end of the Legislative  Session on September 13, 1997, the
Legislature   passed  a  bill  restoring   $203  million  of   education-related
expenditures  which the Governor had vetoed in the original Budget Act, based on
agreement with the Governor on an education testing program. The Governor signed
several bills  implementing a new education testing program,  and is expected to
sign the bill to restore  the  funding.  The  Legislature  also passed a bill to
restore  $48  million of  welfare  cost  savings  which had been part of earlier
legislation  vetoed by the  Governor.  This bill was signed by the  Governor  in
early October.

         Also  prior  to the end of the  Legislative  Session,  the  Legislature
passed  several  bills  encompassing  a coordinated  package of fiscal  reforms,
mostly to take effect after the 1997-98 Fiscal Year. Included in the package are
a variety of  phased-in  tax cuts,  conformity  with certain  provisions  of the
federal  tax reform law passed  earlier in the year,  and reform of funding  for
county trial courts, with the State to assume greater financial  responsibility.
The  Governor  signed  most of these  bills in early  October,  with a few bills
remaining  to be signed.  The  Department  of Finance  estimates  that the major
impact of these fiscal  reforms will occur in Fiscal Year 1998-99 and subsequent
years. The Department  further  estimates that a small projected revenue loss in
Fiscal Year 1997-98 will be more than offset by  increased  Personal  Income Tax
receipts  which will be generated by the new, more  favorable  federal state and
state capital gains tax rate.
    

LITIGATION

   
         Certain  litigation  is pending  against  California  or its officer or
employees  that,  if  decided  adversely,   could  require  the  State  to  make
significant  future  expenditures or could impair future revenue sources.  Among
the more  significant  of these cases are those that involve:  (i) liability for
damages  stemming  from the 1986 Yuba  River  flood.  Damages of  $500,000  were
awarded  to a sample of  plaintiffs.  The  State's  potential  liability  to the
remaining  plaintiffs  ranges from $800 million to $1.5  billion.  An appeal has
been  filed;  (ii) two cases  concerning  AFDC grant  payments,  one  seeking to
invalidate grant reductions and the other challenging the authority of the State
to grant reductions,  with potential liability estimated at $831 million;  (iii)
lawsuits  seeking  reimbursement  for alleged  state-mandated  costs for special
education programs for handicapped  students with potential liability of over $1
billion;  (iv) lawsuits related to contamination at the Stringfellow toxic waste
site  seeking  recovery  for past cost of clean-up  estimated at $200 million to
$800 million;  (v)  challenges to the transfer of over $900 million from Special
fund accounts  within the State Treasury to the State's General Fund pursuant to
the Budget Acts of 1993 - 1996;  (vi)  challenges  to the  amendment of statutes
prescribing  specific  percentages  of  tobacco  tax  revenues  to be  placed in
accounts  to be  used  for  health  education,  research  programs  and  medical
treatment programs involving appropriations of approximately $166 million.
    

ORANGE COUNTY BANKRUPTCY

         On December 6, 1994, Orange County, California (the "County"), together
with its  pooled  investment  funds (the  "Pools")  filed for  protection  under
Chapter 9 of the  federal  Bankruptcy  Code,  after  reports  that the Pools had
suffered  significant  market losses in their  investments,  causing a liquidity
crisis for the Pools and the County.  More than 180 other public entities,  most
of which,  but not all, are located in the County,  were also  depositors in the
Pools. The County has reported the Pools' loss at about $1.69 billion,  or about
23 percent of their initial deposits of approximately $7.5 billion.  Many of the
entities  which  deposited  moneys in the Pools,  including  the  County,  faced
interim and/or extended cash flow difficulties  because of the bankruptcy filing
and may be required to reduce programs or capital projects.

The State has no existing obligation with respect to any outstanding obligations
or securities of the County or any of the other participating entities.

Moody's Investors Service, Inc. ("Moody's")
MUNICIPAL BONDS

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

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

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

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

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

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

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

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

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

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

MUNICIPAL NOTES

     Moody's  ratings  for  Municipal  notes  and  other  short-term  loans  are
designated Moody's Investment Grade (MIG). This distinction is in recognition of
the differences  between short-term and long-term credit risk. Loans bearing the
designation  MIG 1 are  of the  best  quality,  enjoying  strong  protection  by
established  cash  flows of funds  for their  servicing  or by  established  and
broad-based access to the market for refinancing.  Loans bearing the designation
MIG 2 are of high  quality,  with margins of  protection  ample  although not so
large as in the  preceding  group.  Loans bearing the  designation  MIG 3 are of
favorable  quality,  with all security  elements  accounted  for but lacking the
undeniable  strength of the preceding  grades.  Market access for refinancing in
particular, is likely to be less well established. Notes bearing the designation
MIG 4 are 

                                       26
<PAGE>

judged to be of adequate  quality,  carrying specific risk but having protection
commonly  regarded as required of an investment  security and not  distinctly or
predominantly speculative.

COMMERCIAL PAPER

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

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

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

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

STANDARD & POOR'S CORPORATION ("S&P")

MUNICIPAL BONDS

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

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

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

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

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

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

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

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


                                       27
<PAGE>

MUNICIPAL NOTES

     SP-1: Very strong or strong  capacity to pay principal and interest.  Those
issues determined to possess overwhelming safety characteristics will be given a
plus (+) designation.

     SP-2:  Satisfactory capacity to pay principal and interest.

COMMERCIAL PAPER

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

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

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

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

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

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

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

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

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

         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.

         This Statement of Additional  Information  expands upon and supplements
the  information  contained  in  the  current  Prospectus  of  Seligman  Florida
Municipal  Series (the  "Fund"),  dated  February 1, 1998.  It should be read in
conjunction with the Prospectus, 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 the Prospectus in its entirety.
    

         The Fund offers two classes of shares.  Class A shares may be purchased
at net asset value plus a 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 eighteen months of purchase. Class D shares may be purchased
at net asset value and are subject to a CDSL of 1% if redeemed within one year.

         Each  share  of  Class A and  Class D  represents  an  identical  legal
interest in the investment  portfolio of the Fund and has the same rights except
for  certain  class  expenses  and  except  that  Class D  shares  bear a higher
distribution  fee that  generally will cause the 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 and  Class D shares  have  identical  legal  rights,  the  different
expenses borne by each Class will result in different dividends. The two classes
also have different exchange privileges.

                        SELIGMAN FLORIDA MUNICIPAL SERIES

    The Fund is a series of Seligman  Municipal  Series Trust (the  "Trust"),  a
non-diversified   open-end  management   investment  company,  or  mutual  fund,
organized as an  unincorporated  business trust under the laws of  Massachusetts
that commenced operations in 1984.

                    INVESTMENT OBJECTIVE, POLICIES AND RISKS

    The Fund seeks to provide  high income  exempt from regular  federal  income
taxes  consistent  with  preservation  of capital.  The Fund also  invests  with
consideration given to capital gain.

    The Fund is expected to invest principally,  without percentage limitations,
in  municipal  securities  which on the date of  investment  are within the four
highest ratings of Moody's Investors Service,  Inc. ("Moody's") (Aaa, Aa, A, Baa
for bonds;  MIG 1, MIG 2, MIG 3, MIG 4 for notes;  P-1 for commercial  paper) or
Standard & Poor's  Corporation  ("S&P") (AAA, AA, A, BBB for bonds;  SP-1 - SP-2
for notes; A-1+, A-1/A-2 for commercial  paper).  Municipal  securities rated in
these  categories  are commonly  referred to as investment  grade.  The Fund may
invest in municipal  securities  which are not rated,  or which do not fall into
the credit ratings noted above if, based upon credit analysis by the Manager, it
is believed that such  securities  are of  comparable  quality.  In  determining
suitability of investment in a lower rated or unrated security, the Manager will
take into  consideration  asset and debt  service  coverage,  the purpose of the
financing,  history of the issuer,  existence of other rated  securities  of the
issuer and other considerations as may be relevant,  including  comparability to
other issuers.

    Although  securities  rated  in the  fourth  rating  category  are  commonly
referred to as investment  grade,  investment in such  securities  could involve
risks not usually  associated  with bonds  rated in the first three  categories.
Bonds  rated  BBB by S&P  are  more  likely  as a  result  of  adverse  economic
conditions  or  changing  circumstance  to  exhibit a weakened  capacity  to pay
interest and re-pay  principal than bonds in higher rating  categories and bonds
rated Baa by Moody's lack  outstanding  investment  characteristics  and in fact
have speculative  characteristics according to Moody's.  Municipal securities in
the fourth  rating  category of S&P or Moody's will  generally  provide a higher
yield than do higher rated municipal securities of similar maturities;  however,
they are  subject  to a greater  degree of  fluctuation  in value as a result of
changing  interest  rates  and  economic  conditions.  The  market  value of the
municipal  securities will also be affected by the degree of interest of dealers
to bid for them, and in certain  markets  dealers may be more unwilling to trade
municipal  securities  rated in the fourth rating  categories than in the higher
rating categories.

    A  description  of the rating  categories is contained in Appendix A to this
Statement.

    From time to time,  proposals have been  introduced  before Congress for the
purpose of  restricting  or  eliminating  the federal  income tax  exemption for
interest on municipal  securities and for providing state and local  governments
with federal credit assistance. Reevaluation of the Fund's investment objectives
and structure  might be necessary in the future due to market  conditions  which
may result from future changes in the tax laws.

FLORIDA MUNICIPAL SECURITIES.  Florida Municipal Securities include notes, bonds
and  commercial  paper  issued  by or on behalf  of the  State of  Florida,  its
political subdivisions,  agencies, and instrumentalities,  the interest on which
is exempt  from  regular  federal  income  taxes.  Such  securities  are  traded
primarily in an over-the-counter market. The Fund may invest, without percentage
limitations, in certain private activity bonds, the interest on which is treated
as a preference item for purposes of the  alternative  minimum tax. See "Florida
Municipal Securities" in the Prospectus.

    Under  the   Investment   Company  Act  of  1940  (the  "1940   Act"),   the
identification  of the issuer of  municipal  bonds,  notes or  commercial  paper
depends  on the  terms and  conditions  of the  obligation.  If the  assets  and
revenues of an agency, authority, instrumentality or other political subdivision
are  separate  from those of the  government  creating the  subdivision  and the
obligation  is backed only by the assets and revenues of the  subdivision,  such
subdivision  is  regarded  as the  sole  issuer.  Similarly,  in the  case of an
industrial  development  revenue bond or pollution  control revenue bond, if the
bond is backed only by the assets and revenues of the nongovernmental  user, the
nongovernmental  user is  regarded  as the sole  issuer.  If in either  case the
creating government or another entity guarantees an obligation,  the security is
treated  as an  issue  of such  guarantor  to the  extent  of the  value  of the
guarantee.

                                      -2-
<PAGE>

    Municipal  bonds are issued to obtain  funds for  various  public  purposes,
including  the  construction  of a wide  range  of  public  facilities  such  as
airports, bridges, highways,  housing, hospitals, mass transportation,  schools,
streets, water and sewer works, and gas and electric utilities.  Municipal bonds
also may be issued in connection with the refunding of outstanding  obligations,
obtaining funds to lend to other public institutions,  and for general operating
expenses.  Industrial development bonds, which are considered municipal bonds if
the  interest  paid  thereon is exempt  from  regular  federal  income tax (such
interest,  however,  may be subject to the federal alternative minimum tax), are
issued by or on behalf of public  authorities to obtain funds to provide various
privately-operated  facilities for business and manufacturing,  housing, sports,
pollution control, and for airport, mass transit, port and parking facilities.

    The  two  principal   classifications   of  municipal   bonds  are  "general
obligation" and "revenue."  General obligation bonds are secured by the issuer's
pledge of its full faith,  credit and taxing  power for the payment of principal
and interest.  Revenue  bonds are payable only from the revenues  derived from a
particular  facility or class of facilities or, in some cases, from the proceeds
of a special excise tax or other specific  revenue source.  Although  industrial
development  bonds  ("IDBs")  are  issued  by  municipal  authorities,  they are
generally  secured by the revenues derived from payments of the industrial user.
The payment of principal and interest on IDBs is dependent solely on the ability
of the user of the  facilities  financed  by the  bonds  to meet  its  financial
obligations and the pledge, if any, of real and personal property so financed as
security for such payment.

    Municipal Notes  generally are used to provide for short-term  capital needs
and generally have maturities of one year or less. Municipal Notes include:

    1. TAX  ANTICIPATION  NOTES.  Tax  Anticipation  Notes are issued to finance
working  capital  needs  of  municipalities.   Generally,  they  are  issued  in
anticipation of various tax revenues,  such as income,  sales,  use and business
taxes, and are payable from these specific future taxes.

    2. REVENUE  ANTICIPATION  NOTES.  Revenue  Anticipation  Notes are issued in
expectation  of  receipt of other  kinds of  revenue,  such as federal  revenues
available under the Federal Revenue Sharing Programs.

    3. BOND ANTICIPATION  NOTES.  Bond Anticipation  Notes are issued to provide
interim financing until long-term financing can be arranged.  In most cases, the
long-term bonds then provide the money for the repayment of the Notes.

    4.  CONSTRUCTION  LOAN  NOTES.  Construction  Loan Notes are sold to provide
construction financing.  Permanent financing,  the proceeds of which are applied
to the payment of Construction Loan Notes, is sometimes provided by a commitment
by the Government  National Mortgage  Association  ("GNMA") to purchase the loan
notes,  accompanied  by a commitment by the Federal  Housing  Administration  to
insure mortgage advances thereunder. In other instances,  permanent financing is
provided by commitments of banks to purchase the loan notes.

    Issues  of  Municipal  COMMERCIAL  PAPER  typically  represent   short-term,
unsecured, negotiable promissory notes. These obligations are issued by agencies
of state and local  governments  to finance  seasonal  working  capital needs of
municipalities  or to provide interim  construction  financing and are paid from
general  revenues of  municipalities  or are refinanced  with long-term debt. In
most cases,  Municipal Commercial Paper is backed by letters of credit,  lending
agreements,  note  repurchase  agreements  or other credit  facility  agreements
offered by banks or other institutions.

WHEN-ISSUED  SECURITIES.  The  Fund  may  purchase  municipal  securities  on  a
when-issued  basis, in which case delivery and payment normally take place 15 to
45 days after the date of the commitment to purchase. The payment obligation and
the interest  rate that will be received on the  municipal  securities  are each
fixed at the time the buyer enters into the  commitment.  Although the Fund will
only purchase a municipal  security on a when-issued basis with the intention of
actually acquiring the securities, the Fund may sell these securities before the
settlement date if it is deemed advisable.

    Municipal  securities  purchased on a when-issued  basis and the  securities
held in the Fund 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
similar changes in value,  I.E., both  experiencing  appreciation  when interest
rates decline and  depreciation  when interest  rates rise).  Therefore,  to the
extent the Fund 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 

                                      -3-
<PAGE>

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

FLOATING RATE AND VARIABLE RATE SECURITIES.  The Fund may purchase floating rate
and  variable  rate  securities,   including  participation  interests  therein.
Investments  in floating or  variable  rate  securities  normally  will  involve
industrial  development or revenue bonds which provide that the rate of interest
is set as a specific  percentage  of a  designated  base rate,  such as rates on
Treasury Bonds or Bills or the prime rate at a major  commercial  bank, and that
the Fund can  demand  payment  of the  obligations  on short  notice at par plus
accrued interest, which amount may be more or less than the amount the Fund paid
for them.  Variable rate securities provide for a specified periodic  adjustment
in the interest rate, while floating rate securities have an interest rate which
changes  whenever  there is a  change  in the  designated  base  interest  rate.
Frequently  such  securities  are  secured by letters of credit or other  credit
support  arrangements  provided by banks. The quality of the underlying creditor
or of the bank,  as the case may be, must be  equivalent  to the  standards  set
forth with respect to taxable investments on page 5.

STAND-BY COMMITMENTS.  Under a stand-by commitment,  the Fund obligates a dealer
to repurchase at the Fund's option  specified  securities at a specified  price.
The exercise of a stand-by commitment is subject to the ability of the dealer to
make payment on demand.  The Fund would acquire stand-by  commitments  solely to
facilitate portfolio liquidity and not for trading purposes.  Prior to investing
in stand-by commitments the Fund, if it deems necessary based upon the advice of
counsel,  will apply to the Securities and Exchange  Commission for an exemptive
order relating to such  commitments and the valuation  thereof.  There can be no
assurance  that the  Securities  and  Exchange  Commission  will  issue  such an
authorization.

    The price which the Fund would pay for  municipal  securities  with stand-by
commitments  generally  would be higher than the price which  otherwise would be
paid for the municipal securities alone. The Fund will only purchase obligations
with stand-by commitments from sellers the Manager deems creditworthy.

    Stand-by  commitments with respect to portfolio  securities of the Fund with
maturities of less than 60 days which are separate from the underlying portfolio
securities are not assigned a value. The cost of any such stand-by commitment is
carried as an unrealized loss from the time of purchase until it is exercised or
expires.  Stand-by  commitments with respect to portfolio securities of the Fund
with  maturities  of 60 days or more  which  are  separate  from the  underlying
portfolio  securities and the underlying portfolio securities are valued at fair
value as determined in accordance  with  procedures  established by the Board of
Trustees.  The Board of Trustees would, in connection with the  determination of
the value of such a  stand-by  commitment,  consider  among  other  factors  the
creditworthiness of the writer of the stand-by  commitment,  the duration of the
stand-by commitment, the dates on which or the periods during which the stand-by
commitment  may be exercised and the  applicable  rules and  regulations  of the
Securities and Exchange Commission.

TAXABLE  INVESTMENTS.  Under normal market conditions,  the Fund will attempt to
invest  100% and as a matter of  fundamental  policy will invest at least 80% of
the value of its net assets in Florida  Municipal  Securities  the  interest  on
which is exempt from regular federal tax. Such interest, however, may be subject
to the federal  alternative  minimum tax. In abnormal market conditions,  if, in
the judgment of the Manager,  Florida Municipal Securities satisfying the Fund's
investment objectives may not be purchased, the Fund may, for defensive purposes
invest in securities  other than Florida  Municipal  Securities  including those
described under "Florida  Municipal  Securities" above that would otherwise meet
the Fund's objectives.

    Also,  in  abnormal  market  conditions,  the Fund may invest on a temporary
basis in  fixed-income  securities,  the interest on which is subject to regular
federal,  state or local income taxes, pending the investment or reinvestment in
municipal  securities  of  proceeds  of sales of  shares  or sales of  portfolio
securities, in order to avoid the necessity of liquidating portfolio investments
to meet  redemption  of shares by investors or where  market  conditions  due to
rising interest rates or other adverse factors warrant  temporary  investing for
defensive  purposes.  Investments in taxable securities will be substantially in
securities

                                      -4-
<PAGE>

issued or guaranteed by the United States  Government (such as bills,  notes and
bonds), its agencies,  instrumentalities or authorities;  highly-rated corporate
debt securities  (rated AA-, or better,  by Standard & Poor's or Aa3, or better,
by Moody's);  prime commercial paper (rated A-1+/A-1 by Standard & Poor's or P-1
by Moody's);  and  certificates of deposit of the 100 largest  domestic banks in
terms  of  assets  which  are  subject  to  regulatory  supervision  by the U.S.
Government  or state  governments  and the 50 largest  foreign banks in terms of
assets  with  branches  or  agencies  in  the  United  States.   Investments  in
certificates of deposit of foreign banks and foreign  branches of U.S. banks may
involve  certain  risks,  including  different  regulation,   use  of  different
accounting  procedures,  political  or  other  economic  developments,  exchange
controls, or possible seizure or nationalization of foreign deposits.

PORTFOLIO  TURNOVER.  Portfolio  transactions will be undertaken  principally to
accomplish  the Fund's  objective  in relation to  anticipated  movements in the
general  level of  interest  rates but the Fund may also  engage  in  short-term
trading consistent with its objective. Securities may be sold in anticipation of
a market decline (a rise in interest  rates) or purchased in  anticipation  of a
market  rise (a decline  in  interest  rates) and later  sold.  In  addition,  a
security  may be sold and another  purchased at  approximately  the same time to
take advantage of what the Manager  believes to be a temporary  disparity in the
normal yield relationship between the two securities.

   
    The Fund's investment  policies may lead to frequent changes in investments,
particularly  in periods  of rapidly  fluctuating  interest  rates.  A change in
securities held by the Fund is known as "portfolio turnover" and may involve the
payment by the Fund of dealer  spreads or  underwriting  commissions,  and other
transaction costs, on the sale of securities,  as well as on the reinvestment of
the proceeds in other securities.  Portfolio  turnover rate for a fiscal year is
the ratio of the lesser of  purchases or sales of  portfolio  securities  to the
monthly average of the value of portfolio securities.  Securities whose maturity
or expiration date at the time of acquisition were one year or less are excluded
from the calculation.  The Fund's portfolio  turnover rates for the fiscal years
ended  September  30,  1997 and 1996,  respectively,  were  33.68%  and  18.53%,
respectively.  The Fund's portfolio  turnover rate will not be a limiting factor
when the Fund deems it desirable to sell or purchase securities.
    

                             INVESTMENT LIMITATIONS

    Under the Fund's  fundamental  policies,  which cannot be changed  except by
vote of a majority of the  outstanding  voting  securities of the Fund, the Fund
may not:

- -  Borrow  money,  except  from banks for  temporary  purposes  (such as meeting
   redemption  requests or for  extraordinary or emergency  purposes but not for
   the purchase of portfolio  securities)  in an amount not to exceed 10% of the
   value of its total assets at the time the  borrowing  is made (not  including
   the  amount  borrowed).  The Fund  will  not  purchase  additional  portfolio
   securities  if the Fund has  outstanding  borrowings  in  excess of 5% of the
   value of its total assets;

- -  Mortgage or pledge any of its assets,  except to secure permitted  borrowings
   noted above;

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

   agencies and instrumentalities are not considered an industry for purposes of
   this limitation;

- -  As to 50% of the value of its total assets, purchase securities of any issuer
   if immediately  thereafter more than 5% of total assets at market value would
   be invested in the securities of any issuer (except that this limitation does
   not apply to obligations issued or guaranteed as to principal and interest by
   the U.S. Government or its agencies or instrumentalities);

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

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

- -  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  issuer  own in the  aggregate  more than 5% of such
   securities;

                                      -5-
<PAGE>

(d)  Deferred.

   
    The Trust has a compensation  arrangement  under which outside  trustees may
elect to defer receiving their fees. Under this arrangement, interest is accrued
on the deferred balances.  The annual cost of such fees and interest is included
in the  trustees'  fees and expenses,  and the  accumulated  balance  thereof is
included in "Liabilities" in the Trust's financial statements.  The total amount
of deferred compensation (including interest) payable in respect of the Trust to
Mr.  Whitson as of September 30, 1997 was $13,448.  Messrs.  Merow and Pitney no
longer  defer  current   compensation;   however,  they  have  accrued  deferred
compensation  in  the  amounts  of  $39,026  and  $28,133,  respectively,  as of
September 30, 1997. The Fund has applied for and received  exemptive relief that
would permit a director who has elected  deferral of his or her fees to choose a
rate of return  equal to either (i) the  interest  rate on  short-term  Treasury
bills,  or (ii)  the  rate of  return  on the  shares  of any of the  investment
companies advised by the manager,  as designated by the director.  The Fund may,
but is not obligated to, purchase  shares of such investment  companies to hedge
its obligations in connection with this deferral arrangement.
    

    Trustees and officers of the Trust are also trustees, directors and officers
of some or all of the other investment companies in the Seligman Group.

   
    Trustees  and  officers  of the Trust as a group  owned  less than 1% of the
Class A shares of the Fund at January 2, 1998.  No Trustees  or  officers  owned
Class D shares of the Fund at that date.
    

                             MANAGEMENT AND EXPENSES

    Under the Management Agreement,  dated June 21, 1990, subject to the control
of the Trustees,  the Manager  manages the investment of the assets of the Fund,
including making purchases and sales of portfolio securities consistent with the
Fund's  investment  objectives and policies,  and  administers  its business and
other  affairs.   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 Trust 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  the  Fund,
calculated daily and payable monthly, equal to 0.50% of the Fund's average daily
net assets on an annual basis. For the fiscal years ended September 30, 1995 and
1996, the Manager in its discretion, waived all or a portion of its fee from the
Fund, and in some cases also elected to reimburse  certain  expenses of the Fund
for certain  expenses  incurred  during the  periods.  For the fiscal year ended
September 30, 1997,  the management fee paid amounted to $228,202 or .50% of the
Fund's average net assets.
    

    The Fund pays all its  expenses  other  than those  assumed  by the  Manager
including  brokerage  commissions,  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 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 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 Trust's  expenses are
allocated  between  each  series  of the  Trust  in a manner  determined  by the
Trustees to be fair and equitable.

    The Fund's  Management  Agreement  was approved by the Trustees at a meeting
held on June 21, 1990 and was approved by the Florida  shareholders at a Special
Meeting of the Fund held on December 7, 1990.  The  Agreement  will  continue in
effect until December 31 of each year if (1) such continuance is approved in the
manner required by the 1940 Act (i.e., by a


                                      -10-
<PAGE>

vote of a majority of the Trustees or of the  outstanding  voting  securities of
the Fund 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) the
Manager  shall not have  notified the Fund at least 60 days prior to December 31
of any year that it does not  desire  such  continuance.  The  Agreement  may be
terminated  by the Fund,  without  penalty,  on 60 days'  written  notice to the
Manager and will terminate  automatically  in the event of its  assignment.  The
Fund 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 Appendix
B 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  Compliance  Officer,  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
Compliance  Officer,  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 PLAN

    As indicated in the Prospectus, an Administration,  Shareholder Services and
Distribution  Plan (the  "Plan")  for the Fund  will be in effect  from the date
hereof under Section 12(b) of the 1940 Act and Rule 12b-1 thereunder.

    The Plan was approved on June 21, 1990 by the Trustees, including a majority
of the Trustees who are not "interested persons" (as defined in the 1940 Act) of
the Fund and who have no direct or indirect  financial interest in the operation
of the Plan or in any Agreement  related to the Plan (the "Qualified  Trustees")
and by the shareholders of the Fund on December 7, 1990.  Amendments to the Plan
were  approved  in respect  of the Class D shares on  November  18,  1993 by the
Trustees,  including a majority of the Qualified  Trustees and became  effective
with respect to the Class D shares on February 1, 1994.  The Plan will  continue
in effect until December 31 of each year so long as such continuance is approved
annually by a majority  vote of both the Trustees of the Fund and the  Qualified
Trustees,  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  without the approval of a majority of the outstanding
voting securities of the Fund and no material  amendment to the Plan may be made
except by a majority of both the Trustees and the Qualified Trustees.

    The Plan  requires  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)  under the Plan.  Rule 12b-1 also
requires that the selection and  nomination of Trustees who are not  "interested
persons" of the Trust be made by such disinterested Trustees.

                             PORTFOLIO TRANSACTIONS

   
    No brokerage commissions were paid by the Fund during the fiscal years ended
September 30, 1997, 1996 or 1995. When the Fund or 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  already  obtainable
or saleable.
    

                     PURCHASE AND REDEMPTION OF FUND SHARES

    The Fund issues two classes of shares:  Class A shares may be purchased at a
price equal to the next determined net asset value per share, plus a 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 of 1% if such shares are redeemed
within eighteen  months 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 certain  redemptions  within one year of purchase.  See
"Alternative  Distribution  System,"  "Purchase of Shares," and  "Redemption  of
Shares" in the Fund's Prospectus.

SPECIMEN PRICE MAKE-UP

   
    Under  the  current  distribution  arrangements  between  the  Trust and the
Distributor,  Class A shares are sold at a maximum sales load of 4.75% and Class
D shares  are sold at net asset  value.*  Using the  Fund's  net asset  value at
September  30,  1997,  the  maximum  offering  price of the Fund's  shares is as
follows:

    CLASS A

     Net asset value per share......................................    $7.80

     Maximum sales load (4.75% of offering price)...................      .39

- --------------
*    Class D shares are subject to a CDSL of 1% on  redemptions  within one year
     of purchase. Class A shares purchased at net asset value due to the size of
     the  purchase  are subject to a CDSL of 1% on  redemption  within  eighteen
     months of  purchase  of such  shares.  See  "Redemption  of  Shares" in the
     Prospectus.
    

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 the Fund alone, the other series of the Trust 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 the Prospectuses.

   
     THE RIGHT OF  ACCUMULATION  allows an investor to combine the amount  being
invested in Class A shares of the Fund, the other series of the Trust and shares
of 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 which were acquired  through an exchange of shares
of another Seligman
    

                                      -12-
<PAGE>

   
Mutual Fund on which there was an initial  sales load at the time of purchase to
determine   reduced  sales  loads  in  accordance   with  the  schedule  in  the
Prospectuses.  The value of the shares  owned,  including the value of shares of
Seligman  Cash  Management  Fund  acquired  in an  exchange of shares of another
Seligman  Mutual  Fund on which  there 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
dealer of the  amount  owned at the time of  purchase  is made and is  furnished
sufficient information to permit confirmation.

     A LETTER OF INTENT  allows an investor  to  purchase  Class A shares of the
Fund over a 13-month  period at reduced  initial sales loads in accordance  with
the  schedule in the  Prospectuses,  based on the total amount of Class A shares
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 series of
the Trust and other Seligman  Mutual Funds already owned and the total net asset
value of shares of Seligman Cash Management Fund which were acquired  through an
exchange of shares of another Seligman Mutual Fund on which there was an initial
sales load at the time of purchase.  Reduced  initial 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 -
Class A Shares" in the Prospectus.
    

     Class A shares  purchased  without an initial sales load in accordance with
the sales  load  schedule  in the 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 the Fund 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 (the "Code"),  tax-exempt  organizations  under
Section 501 (c)(3) or (13) of the Code, and non-qualified employee benefit plans
that satisfy uniform criteria are considered  "single persons" for this purpose.
The uniform criteria are as follows:

1.  Employees must authorize the employer,  if requested by the Fund, to receive
    in bulk and to  distribute  to each  participant  on a timely basis the Fund
    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 the  Prospectus
applies  to sales to  "eligible  employee  benefit  plans"  (as  defined  in the
Prospectus),  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  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 funding or other systems  acceptable to Seligman Data Corp.,  the
Trust'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.

FURTHER  TYPES OF  REDUCTIONS.  Class A shares 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  financial
institution trust  departments,  to registered  investment  advisers  exercising
investment  discretionary 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

                                      -13-

agreement with SFSI; to financial  institution trust departments;  to registered
investment advisers exercising  discretionary  investment authority with respect
to the  purchase  of Fund  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  Fund;  to  other  investment
companies in the Seligman  Group in connection  with a deferred fee  arrangement
for outside  directors;  and to "eligible  employee benefit plans" which have at
least (i)  $500,000  invested in the  Seligman  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 Fund  shares.  Sales of shares to such  plans  must be made in
connection  with a payroll  deduction  system of plan  funding  or other  system
acceptable to Seligman Data Corp.
    

    Class A  shares  may be sold at net  asset  value  to  present  and  retired
trustees, directors,  officers, employees (and family members, as defined in the
Prospectus) of the Fund, the other  investment  companies in the Seligman Group,
the Manager and other companies affiliated with the Manager. Such sales also may
be made to  employee  benefit  plans  for  such  persons  and to any  investment
advisory,  custodial, trust or other fiduciary account managed or advised by the
Manager 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.

PAYMENT IN SECURITIES.  In addition to cash,  the Fund may accept  securities in
payment for Fund shares sold at the applicable public offering price. Generally,
the Fund will only consider accepting securities (1) to increase its holdings in
a portfolio  security of the Fund,  or (2) if the  Manager  determines  that the
offered  securities  are  a  suitable  investment  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  with  securities,  may  require  partial  payment  in cash  for
applicable sales loads, and may discontinue  accepting securities as payment for
shares  at any  time  without  notice.  The  Fund has no  present  intention  of
accepting securities in payment for shares.

MORE ABOUT  REDEMPTIONS.  The  procedures  for  redemption  of Fund shares under
ordinary  circumstances are set forth in the Prospectus.  Payment may be made in
securities  or postponed,  or the right of redemption  may be suspended for more
than seven days, if the orderly liquidation of portfolio securities is prevented
by the closing of, or restricted  trading on, the New York Stock Exchange during
periods of emergency,  or during such other periods as ordered by the Securities
and Exchange Commission.  If payment were to be made in securities  shareholders
receiving  securities could incur certain  transaction  costs. The Fund will not
accept orders from securities dealers for the repurchase of shares.

                              DISTRIBUTION SERVICES

    SFSI, an affiliate of the Manager, acts as general distributor of the shares
of the Trust and of the other  mutual funds in the  Seligman  Group.  As general
distributor of the Fund's shares of beneficial interest, SFSI allows commissions
to all dealers of up to 4.25% on  purchases of Class A shares to which the 4.75%
sales load  applies.  SFSI  receives the balance of sales loads or any CDSL,  if
applicable,  paid by investors. The Trust and SFSI are parties to a Distributing
Agreement dated January 1, 1993.

   
    Total sales loads paid by  shareholders  of the Fund for fiscal  years ended
September 30, 1997, 1996 and 1995,  respectively,  amounted to $76,147,  $82,207
and $106,160, respectively, of which $66,804, $72,852 and $93,763, respectively,
were paid as  commissions  to dealers.  For the years ended  September 30, 1997,
1996 and 1995, SFSI retained CDSL charges of $0, $138 and $189, respectively.

    Effective April 1, 1995,  Seligman Services,  Inc. ("SSI"),  an affiliate of
the Manager,  became eligible to receive  commissions from certain sales of Fund
shares,  as well as distribution  and service fees pursuant to the Plan. For the
fiscal  years  ended  September  30,  1997 and 1996,  and for the  period  ended
September  30,  1995,  SSI  received  commissions  of  $1,118,  $1,101 and $213,
respectively,  from sales of Fund shares.  SSI also  received  distribution  and
service fees of $5,302, $5,070 and $2,225, respectively, pursuant to the Plan.

                                      TAXES

   
    Under the Code,  each  Series of the Trust  will be  treated  as a  separate
corporation for federal income tax purposes. As a result,  determinations of net
investment  income,  exempt interest  dividends and net long-term and short-term
capital gain and loss will be made separately for each Series.

    As indicated in the Prospectus,  the Fund intends to qualify and elect to be
treated as a regulated investment company under the Code and thus to be relieved
of federal income tax on amounts  distributed to shareholders;  provided that it
distributes at least 90% of its net investment income and net short-term capital
gains, if any.

    Qualification  as a regulated  investment  company  under the Code  requires
among other things, that (a) at least 90% of the annual gross income of the Fund
be derived from dividends,  interest,  payments with respect to securities loans
and  gains  from  the  sale  or  other  disposition  of  stocks,  securities  or
currencies,  or other income  (including  but not limited to gains from options,
futures,  and  forward  contracts)  derived  with  respect  to its  business  of
investing in such stocks, securities or currencies; and (b) the Fund diversifies
its  holdings so that,  at the end of each quarter of the taxable  year,  (i) at
least 50% of the  market  value of the  Fund's  assets is  represented  by cash,
United States Government  securities and other securities  limited in respect of
any one issuer to an amount not greater than 5% of the Fund's  assets and 10% of
the outstanding  voting securities of such issuer, and (ii) not more than 25% of
the value of its assets is invested in the  securities  of any one issuer (other
than U.S. Government securities).
    

                                    VALUATION

   
    The net asset value per share of each class of the Fund is  determined as of
the close of regular trading on the New York Stock Exchange ("NYSE")  (normally,
4:00  p.m.,  Eastern  time) on each day that the NYSE is open.  The Fund and the
NYSE are  currently  closed on New Year's  Day,  Martin  Luther  King,  Jr. Day,
Presidents'  Day,  Good  Friday,  Memorial  Day,  Independence  Day,  Labor Day,
Thanksgiving  Day, and  Christmas  Day. The Fund will also  determine  net asset
value  for  each  class on each day in which  there is a  sufficient  degree  of
trading  in the Fund's  portfolio  securities  that the net asset  value of Fund
shares might be materially affected. Net asset value per share for each class is
computed  by dividing  such  class'  share of the value of the net assets of the
Fund (i.e.,  the value of its assets less  liabilities)  by the total  number of
outstanding  shares of such  class.  All  expenses  of the Fund,  including  the
Manager's  fee,  are  accrued  daily and taken into  account  for the purpose of
determining  its net asset  value.  The net asset  value of Class D shares  will
generally be lower than the net asset value of Class A shares as a result of the
higher distribution fee with respect to Class D shares. It is expected, however,
that the net  asset  value per share of the two  classes  will tend to  converge
immediately after the recording of dividends, which will differ by approximately
the amount of the  distribution  and other class expenses  accrual  differential
between the classes.
    

    Florida  municipal  securities  will be valued  on the  basis of  quotations
provided by an independent pricing service, approved by the Trustees, which uses
information with respect to transactions in bonds, quotations from bond dealers,
market transactions in comparable  securities and various  relationships between
securities  in  determining  value.  In  the  absence  of  such  quotations,  in
accordance with fair value as determined in accordance with procedures  approved
by the Trustees. Short-term notes having remaining maturities of 60 days or less
are generally valued at amortized cost.

    Generally,  trading  in certain  securities  such as  municipal  securities,
corporate bonds, U.S.  Government  securities,  and money market  instruments is
substantially  completed  each day at  various  times  prior to the close of the
NYSE. The values of such  securities  used in determining the net asset value of
the Fund shares are computed as of such times.  Occasionally,  events  affecting
the value of such  securities  may occur between such times and the close of the
NYSE  which will not be  reflected  in the  computation  of the Fund's net asset
value. If events materially  affecting the value of such securities occur during
such period, then these securities and other assets will be valued at their fair
market value as determined in good faith by the Trustees.


                             PERFORMANCE INFORMATION

   
    The annualized  yield for the 30-day period ended September 30, 1997 for the
Fund's Class A shares was 4.07%.  The annualized  yield was computed by dividing
the Fund's net  investment  income per share earned during this 30-day period by
    

                                      -15-
<PAGE>

   
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 September 30, 1997 which was
the last day of the period. The average number of Class A shares of the Fund was
5,441,808  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  (which  includes  fees  charged  pursuant to the Fund's 12b-1
plan). 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 the Prospectus.

    The tax equivalent  annualized  yield for the 30-day period ended  September
30, 1997 for the Fund's Class A shares was 6.74%. The tax equivalent  annualized
yield was computed by first computing the annualized  yield as discussed  above.
Then the portion of the yield attributable to securities the income of which was
exempt for federal income tax purposes was determined. This portion of the yield
was then  divided by one minus 39.6% (39.6%  being the assumed  maximum  federal
income tax rate for individual taxpayers).

    The  average  annual  total  return  for the  Fund's  Class A shares for the
one-year  period ended  September 30, 1997 was 2.91%;  for the five-year  period
ended September 30, 1997 was 5.89%;  and for the ten-year period ended September
30, 1997 was 8.76%.  These  returns  were  computed  by assuming a  hypothetical
initial  payment of $1,000.  From this $1,000,  the maximum sales load of $47.50
(4.75% of public offering  price) was deducted.  It was then assumed that all of
the dividends and  distributions  paid by the Fund over the relevant time period
were  reinvested.  It was  then  assumed  that at the  end of each of the  above
periods,  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 annualized  yield for the 30-day period ended September 30, 1997 for the
Fund's Class D shares was 3.53%.  The annualized yield was computed as for Class
A shares by dividing a Series' net  investment  income per share  earned  during
this 30-day period by the maximum  offering price per share (i.e., the net asset
value) on September 30, 1997, which was the last day of this period. The average
number of Class D shares  was  212,904  which was the  average  daily  number of
shares  outstanding  during  the 30-day  period  that were  eligible  to receive
dividends.

    The tax equivalent  annualized  yield for the 30-day period ended  September
30,  1997 for each the  Fund's  Class D shares  was  5.84%.  The tax  equivalent
annualized yield was computed as discussed above for Class A shares.

    The  average  annual  total  return  for the  Fund's  Class D shares for the
one-year period ended  September 30, 1997 was 6.18% and since inception  through
the period ended  September  30, 1997 was 3.98%.  These returns were computed by
assuming a hypothetical initial payment of $1,000 in Class D shares and that all
of the  dividends  and  distributions  by the  Fund's  Class D  shares  over the
relevant  time periods were  reinvested.  It was then assumed that at the end of
each  period,  the  entire  amount was  redeemed,  subtracting  the 1% CDSL,  if
applicable.

    The following tables  illustrate the total returns on a $1,000 investment in
Class A and Class D shares of the Fund from the commencement of their operations
through  September  30, 1997,  assuming  investment of all dividends and capital
gain distributions.

2   The "Value of Initial  Investment"  as of the dates  indicated  reflects the
    effect of the maximum sales load and CDSL, if  applicable,  assumes that all
    dividends  and capital  gain  distributions  were taken in cash and reflects
    changes in the net asset value of the shares purchased with the hypothetical
    initial investment.  "Total Value of Investment"  reflects the effect of the
    CDSL,  if  applicable,  and assumes  investment of all dividends and capital
    gain distributions.
    

3   Total return for the Fund is calculated by assuming a  hypothetical  initial
    investment of $1,000 at the beginning of the period  specified,  subtracting
    the maximum sales load or CDSL, if  applicable;  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; and finally, by dividing the difference
    between the amount of the hypothetical  initial  investment at the beginning
    of the  period  and its value at the end of the  period by the amount of the
    hypothetical initial investment.

    The  waiver  by  the  Manager  of all  or a  portion  of  its  fee  and  the
reimbursement  of certain Fund  expenses  during the periods (as set forth under
"Management and Expenses"  herein and "Financial  Highlights" in the Prospectus)
positively affected the performance results provided in this section.

    The Fund's total return and average  annual total return quoted from time to
time  through   December  27,  1990  does  not  reflect  the  deduction  of  the
administration,   shareholder  services  and  distribution  fee,  which  fee  if
reflected would reduce the performance quoted.

                               GENERAL INFORMATION

    The Trustees are  authorized to classify or reclassify  and issue any shares
of  beneficial  interest of the Trust into any number of other  classes  without
further action by  shareholders.  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.

    As a general matter, the Trust 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 Trust or any series, including the Fund, 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 Trust 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 Trust or the  shareholders,  and (f) with
respect to such additional  matters  relating to the Trust as may be required by
the  1940  Act,  the  Declaration  of  Trust,  the  By-laws  of the  Trust,  any
registration  of the Trust 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 Trust  have the  right,  upon the  declaration  in
writing or vote of more than two-thirds of the Trust'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 Trustee  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 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  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
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  to be
submitted  by the  provisions  of the  1940  Act or  applicable  state  law,  or
otherwise,  to the holders of the outstanding voting securities of an investment
company  such as the Trust  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 each 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  public  accountants,  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.

       RISK FACTORS REGARDING INVESTMENTS IN FLORIDA MUNICIPAL SECURITIES

    The following  information as to certain Florida  considerations is given to
investors  in view of the Fund's  policy of  concentrating  its  investments  in
Florida  issues.  This  information  is derived from sources that are  generally
available  to  investors  and  is  believed  to be  accurate.  This  information
constitutes only a brief summary,  does not purport to be a complete description
and has not been independently verified.

    Florida's  financial  operations are considerably  different than most other
states because, under the State's constitution,  there is no state income tax on
individuals.  Florida's  constitution prohibits the levy, under the authority of
the State,  of an individual  income tax upon the income of natural  persons who
are  residents or citizens of Florida in excess of amounts which may be credited
against or  deducted  from any  similar  tax levied by the United  States or any
other  state.  Accordingly,  a  constitutional  amendment  would be necessary to
impose a state individual  income tax in excess of the foregoing  constitutional
limitations.  The lack of an income tax exposes total State tax  collections  to
more  volatility  than  would  otherwise  be the case  and,  in the  event of an
economic  downswing,  could  affect the  State's  ability to pay  principal  and
interest in a timely  manner.  Florida has a  proportionally  greater  number of
persons of retirement age; a factor that makes  Florida's  property and transfer
payment  taxes a relatively  more  important  source of State  funding.  Because
transfer  payments are  typically  less  sensitive  to the  business  cycle than
employment income, they may act as a stabilizing force in weak economic periods.

   
    Florida imposes an income tax on corporate income allocable to the State, as
well as an ad valorem tax on intangible  personal property,  sales and use taxes
and other  miscellaneous  taxes. These taxes are a major source of funds to meet
state  expenses,  including  repayment of, and interest on,  obligations  of the
State.  Financial  operations of the State of Florida  covering all receipts and
expenditures  are maintained  through the use of four funds (the General Revenue
Fund, Trust Funds, the Working Capital Fund and The Budget  Stabilization Fund).
The General Revenue Fund receives the majority of State tax revenues.  The Trust
Funds consist of monies received by the State which under law or trust agreement
are segregated for a purpose  authorized by law. Revenues in the General Revenue
Fund  which are in excess of the  amount  needed to meet  appropriations  may be
transferred to the Working Capital Fund. The Florida  Constitution  and Statutes
mandate  that the  State  budget be kept in  balance  from  currently  available
revenues each State fiscal year (July 1 - June 30). For fiscal year 1997-98, the
estimated  total funds  available are reported to be $42 billion.  The estimated
General   Revenue   plus   Working   Capital  and  Budget   Stabilization   Fund
appropriations  at July 1997 are estimated at $17.114 billion with  unencumbered
reserves at the end of fiscal year  1997-98  estimated  at $1.036  million.  For
fiscal year 1997-98,  the  estimated  General  Revenue plus Working  Capital and
Budget  Stabilization  Funds are projected to be $18.110 billion,  a 9% increase
over the estimated $16.6 billion  available in fiscal year 1996-97.  The Florida
and U.S.  unemployment  rates  for  1996  were  5.05%  and  5.4%,  respectively.
Unemployment  figures at the end of third quarter 1997 showed U.S.  unemployment
rates  hitting  a  twenty-four  year  low  of  4.7%  with  the  average  Florida
unemployment rate for the year at 4.88%.
    

    In 1993,  Florida's  constitution  was amended to limit the annual growth in
the assessed  valuation of residential  property,  and which,  over time,  could
constrain  growth  in  property  taxes,  a major  source  of  revenue  for local
governments. While no immediate ratings implications are expected, the amendment
could have a negative impact on the financial  performance of local  governments
over time and lead to ratings  revisions which may have a negative impact on the
prices of affected bonds. In 1994, the Florida constitution was amended to limit
state revenue  collections  in any fiscal year to,  subject to  exception,  that
which  was  allowed  in the  prior  fiscal  year  plus a  growth  factor,  to be
determined by reference to the average  annual  growth rate in Florida  personal
income over the previous five years.

   
    Florida has historically  experienced  substantial population increases as a
result of migration  to Florida  from other areas of the United  States and from
foreign  countries,  although  recent  population  growth  has  been  modest  by
historical  standards.  Between 1960 and 1995,  Florida's population grew by 9.2
million people,  a 185% increase or more than 4 times the 46% growth rate in the
U.S.  population over the same period.  However,  after rising from 1992 to 1993
from 1.4% to 2.1% in 1993-94,  population growth has leveled off, moving from an
estimated  1.9% in  1994-95  to 1.85% in  1996-97;  the  general  population  is
expected to grow at 1.8% in 1997-98. As a result of population growth, the State
may experience a need for additional  revenues to meet increased  burdens on the
various public and social services  provided by the State.  Florida's ability to
obtain  increased  revenues to meet these burdens will be dependent in part upon
the State's ability to foster business and economic growth. The State's business
and  economic  growth  could  be  restricted  by  the  natural   limitations  of
environmental  resources  and the  State's  ability to finance  adequate  public
facilities such as roads and schools.

    Despite  increases in other sectors of its economy,  Florida remains heavily
dependent on tourism. Three years ago Florida tourism was negatively impacted by
the effects of publicity regarding crime against tourists in the state,  product
maturity,  higher  prices and more  aggressive  marketing by competing  vacation
destinations.  In 1994, slightly less than 40 million persons visited Florida on
an  annual  basis.   Since  then  tourism  has  been   improving.   In  1996-97,
approximately  43 million visitors were recorded and the forecast for 1997-98 is
44.6 million  visitors,  an increase of 3.7%.  Estimates for 1998-99 call for an
additional  900,000  visitors  annually,  rising to 45.5  million.  Despite such
optimism,  the tourism  industry  can be very  volatile  predicated  on numerous
uncontrolled  factors  such  as  good  public  relations,   weather,  access  to
reasonably priced transportation and disposable income.

    Housing starts from 1991 through 1996 averaged 111,279 units annually in the
State of Florida.  Results for 1995 showed 119,775 units  constructed;  in 1996,
122,380  units were  built.  Estimates  show  increasing  numbers of units being
constructed  in the next two years.  Housing starts are,  however,  reliant upon
interest rates and disposable income,  which can significantly  impact demand in
the  event of an  economic  downturn.  There  has been a  decline  in  Florida's
dependence   on   highly   cyclical   construction   and    construction-related
manufacturing  sectors. For example, the total contract construction  employment
as a share of total non-farm  employment reached a peak of 10% in 1973. In 1980,
the share was roughly 7.5% and in 1997 the share had  reportedly  edged downward
to nearly  2.5%.  This  trend is  expected  to  continue  as  Florida's  economy
continues to diversify.
    

    The  ability of the State and its local units of  government  to satisfy its
debt  obligations  may be  affected  by  numerous  factors  which  impact on the
economic vitality of the State in general and the particular region of the State
in which  the  issuer of the debt  obligations  in  located.  South  Florida  is
particularly  susceptible to international  trade and currency imbalances and to
economic  dislocations  in Central and South  America,  due to its  geographical
location and its involvement with foreign trade, tourism and investment capital.
North and central Florida are impacted by problems in the  agricultural  sector,
particularly with regard to the citrus and sugar industries.  Short-term adverse
economic  conditions may be created in these areas, and in the State as a whole,
due to crop  failures,  severe weather  conditions or other  agriculture-related
problems.  The State economy also has historically been dependent on the tourism
and  construction  industries  and is,  therefore,  sensitive to trends in those
sectors.

    The Fund's  investment  values are expected to vary in  accordance  with the
Fund's  investment  ratings,  the issuer's  ability to satisfy  interest  and/or
principal  payment  obligations,  the relative interest rates payable on similar
investments,  and the  legal  environment  relating  to  creditors'  rights.  In
addition to the foregoing risk factors,  the Fund's policy of concentrating  its
investments  in Florida  municipal  securities  may make it more  susceptible to
risks of adverse  economic,  political or regulatory  developments than would be
the case if the Fund were more diversified as to geographic region and/or source
of revenue.

                                   APPENDIX A

MOODY'S INVESTORS SERVICE, INC. ("MOODY'S")
MUNICIPAL BONDS

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

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

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

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

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

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

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

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

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

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

MUNICIPAL NOTES

    Moody's  ratings  for  municipal  notes  and  other   short-term  loans  are
designated Moody's Investment Grade (MIG). This distinction is in recognition of
the differences  between short-term and long-term credit risk. Loans bearing the
designation  MIG 1 are  of the  best  quality,  enjoying  strong  protection  by
established  cash  flows of funds  for their  servicing  or by  established  and
broad-based access to the market for refinancing.  Loans bearing the designation
MIG 2 are of high  quality,  with margins of  protection  ample  although not so
large as in the  preceding  group.  Loans bearing the  designation  MIG 3 are of
favorable  quality,  with all security  elements  accounted  for but lacking the
undeniable  strength of the preceding  grades.  Market access for refinancing in
particular, is likely to be less well established. Notes bearing the designation
MIG 4 are 

                                      -21-
<PAGE>

judged to be of adequate  quality,  carrying specific risk but having protection
commonly  regarded as required of an investment  security and not  distinctly or
predominantly speculative.

COMMERCIAL PAPER

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

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

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

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

STANDARD & POOR'S CORPORATION ("S&P")
MUNICIPAL BONDS

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

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

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

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

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

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

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

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

                                      -22-
<PAGE>

MUNICIPAL NOTES

    SP-1:  Very strong or strong  capacity to pay principal and interest.  Those
issues determined to possess overwhelming safety characteristics will be given a
plus (+) designation.

    SP-2:  Satisfactory capacity to pay principal and interest.

COMMERCIAL PAPER

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

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

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

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

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

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

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

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

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

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

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

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

THE SELIGMAN COMPLEX:

 ...Prior to 1900

o     Helps finance America's fledgling railroads through underwritings.
o     Is admitted to the New York Stock  Exchange in 1869.  Seligman  remained a
      member of the NYSE until 1993,  when the evolution of its business made it
      unnecessary.
o     Becomes a prominent  underwriter  of corporate  securities,  including New
      York Mutual Gas Light Company, later part of Consolidated Edison.
o     Provides financial assistance to Mary Todd Lincoln and urges the Senate to
      award her a pension.

      some of the  Country's  largest  companies:  Briggs  Manufacturing,  Dodge
      Brothers, General Motors, Minneapolis-Honeywell Regulatory Company, Maytag
      Company United Artists Theater Circuit and Victor Talking Machine Company.
o     Forms  Tri-Continental  Corporation in 1929,  today the nation's  largest,
      diversified  closed-end equity investment company, with over $2 billion in
      assets and one of its oldest.

 ...1930s

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

         This Statement of Additional  Information  expands upon and supplements
the information  contained in the current  Prospectus of Seligman North Carolina
Municipal  Series (the  "Fund"),  dated  February 1, 1998.  It should be read in
conjunction with the Prospectus, 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 the Prospectus in its entirety.
    

         The Fund offers two classes of shares.  Class A shares may be purchased
at net asset value plus a 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 eighteen months of purchase. Class D shares may be purchased
at net asset value and are subject to a CDSL of 1% if redeemed within one year.

         Each  share  of  Class A and  Class D  represents  an  identical  legal
interest in the investment  portfolio of the Fund and has the same rights except
for  certain  class  expenses  and  except  that  Class D  shares  bear a higher
distribution  fee that  generally will cause the 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 and  Class D shares  have  identical  legal  rights,  the  different
expenses borne by each Class will result in different dividends. The two classes
also have different exchange privileges.

                    SELIGMAN NORTH CAROLINA MUNICIPAL SERIES

    The Fund is a series of Seligman  Municipal  Series Trust (the  "Trust"),  a
non-diversified   open-end  management   investment  company,  or  mutual  fund,
organized as an  unincorporated  business trust under the laws of  Massachusetts
that commenced operations in 1984.

                    INVESTMENT OBJECTIVE, POLICIES AND RISKS

    The Fund seeks to provide  high income  exempt from regular  federal  income
taxes  and  the  personal  income  taxes  of  North  Carolina   consistent  with
preservation  of capital.  The Fund also  invests  with  consideration  given to
capital gain.

    The Fund is expected to invest principally,  without percentage limitations,
in  municipal  securities  which on the date of  investment  are within the four
highest ratings of Moody's Investors Service,  Inc. ("Moody's") (Aaa, Aa, A, Baa
for bonds;  MIG 1, MIG 2, MIG 3, MIG 4 for notes;  P-1 for commercial  paper) or
Standard & Poor's  Corporation  ("S&P") (AAA, AA, A, BBB for bonds;  SP-1 - SP-2
for notes; A-1+, A-1/A-2 for commercial  paper).  Municipal  securities rated in
these  categories  are commonly  referred to as investment  grade.  The Fund may
invest in municipal  securities  which are not rated,  or which do not fall into
the credit ratings noted above if, based upon credit analysis by the Manager, it
is believed that such  securities  are of  comparable  quality.  In  determining
suitability of investment in a lower rated or unrated security, the Manager will
take into  consideration  asset and debt  service  coverage,  the purpose of the
financing,  history of the issuer,  existence of other rated  securities  of the
issuer and other considerations as may be relevant,  including  comparability to
other issuers.

    Although  securities  rated  in the  fourth  rating  category  are  commonly
referred to as investment  grade,  investment in such  securities  could involve
risks not usually  associated  with bonds  rated in the first three  categories.
Bonds  rated  BBB by S&P  are  more  likely  as a  result  of  adverse  economic
conditions  or  changing  circumstance  to  exhibit a weakened  capacity  to pay
interest and re-pay principal than bonds in higher rating categories,  and bonds
rated Baa by Moody's lack  outstanding  investment  characteristics  and in fact
have speculative  characteristics according to Moody's.  Municipal securities in
the fourth  rating  category of S&P or Moody's will  generally  provide a higher
yield than do higher rated municipal securities of similar maturities;  however,
they are  subject  to a greater  degree of  fluctuation  in value as a result of
changing  interest  rates  and  economic  conditions.  The  market  value of the
municipal  securities will also be affected by the degree of interest of dealers
to bid, for them, and in certain  markets dealers may be more unwilling to trade
municipal  securities  rated in the fourth rating  categories than in the higher
rating categories.

    A description of the credit rating  categories is contained in Appendix A to
this Statement.

    From time to time,  proposals have been  introduced  before Congress for the
purpose of  restricting  or  eliminating  the federal  income tax  exemption for
interest on municipal  securities and for providing state and local  governments
with federal credit assistance. Reevaluation of the Fund's investment objectives
and structure  might be necessary in the future due to market  conditions  which
may result from future changes in the tax laws.

NORTH CAROLINA MUNICIPAL SECURITIES. North Carolina Municipal Securities include
notes,  bonds and commercial  paper issued by or on behalf of the State of North
Carolina,  its political  subdivisions,  agencies,  and  instrumentalities,  the
interest on which is exempt from regular federal income taxes and North Carolina
state  personal  income  taxes.  Such  securities  are  traded  primarily  in an
over-the-counter market. The Fund may invest, without percentage limitations, in
certain private activity bonds, the interest on which is treated as a preference
item for purposes of the alternative  minimum tax. See "North Carolina Municipal
Securities" in the Prospectus.

    Under  the   Investment   Company  Act  of  1940  (the  "1940   Act"),   the
identification  of the issuer of  municipal  bonds,  notes or  commercial  paper
depends  on the  terms and  conditions  of the  obligation.  If the  assets  and
revenues of an agency, authority, instrumentality or other political subdivision
are  separate  from those of the  government  creating the  subdivision  and the
obligation  is backed only by the assets and revenues of the  subdivision,  such
subdivision  is  regarded  as the  sole  issuer.  Similarly,  in the  case of an
industrial  development  revenue bond or pollution  control revenue bond, if the
bond is backed only 

                                      -2-
<PAGE>

by the assets and revenues of the nongovernmental user, the nongovernmental user
is regarded as the sole  issuer.  If in either case the creating  government  or
another entity guarantees an obligation,  the security is treated as an issue of
such guarantor to the extent of the value of the guarantee.

    Municipal  bonds are issued to obtain  funds for  various  public  purposes,
including  the  construction  of a wide  range  of  public  facilities  such  as
airports, bridges, highways,  housing, hospitals, mass transportation,  schools,
streets, water and sewer works, and gas and electric utilities.  Municipal bonds
also may be issued in connection with the refunding of outstanding  obligations,
obtaining funds to lend to other public institutions,  and for general operating
expenses.  Industrial development bonds, which are considered municipal bonds if
the  interest  paid  thereon is exempt  from  regular  federal  income tax (such
interest,  however,  may be subject to the federal alternative minimum tax), are
issued by or on behalf of public  authorities to obtain funds to provide various
privately-operated  facilities for business and manufacturing,  housing, sports,
pollution control, and for airport, mass transit, port and parking facilities.

    The  two  principal   classifications   of  municipal   bonds  are  "general
obligation" and "revenue."  General obligation bonds are secured by the issuer's
pledge of its full faith,  credit and taxing  power for the payment of principal
and interest.  Revenue  bonds are payable only from the revenues  derived from a
particular  facility or class of facilities or, in some cases, from the proceeds
of a special excise tax or other specific  revenue source.  Although  industrial
development  bonds  ("IDBs")  are  issued  by  municipal  authorities,  they are
generally  secured by the revenues derived from payments of the industrial user.
The payment of principal and interest on IDBs is dependent solely on the ability
of the user of the  facilities  financed  by the  bonds  to meet  its  financial
obligations and the pledge, if any, of real and personal property so financed as
security for such payment.

    Municipal Notes  generally are used to provide for short-term  capital needs
and generally have maturities of one year or less. Municipal Notes include:

1.  TAX ANTICIPATION NOTES. Tax Anticipation Notes are issued to finance working
    capital needs of municipalities.  Generally, they are issued in anticipation
    of various tax revenues,  such as income, sales, use and business taxes, and
    are payable from these specific future taxes.

2.  REVENUE  ANTICIPATION  NOTES.  Revenue  Anticipation  Notes  are  issued  in
    expectation of receipt of other kinds of revenue,  such as federal  revenues
    available under the Federal Revenue Sharing Programs.

3.  BOND  ANTICIPATION  NOTES.  Bond  Anticipation  Notes are  issued to provide
    interim financing until long-term financing can be arranged.  In most cases,
    the long-term bonds then provide the money for the repayment of the Notes.

4.  CONSTRUCTION  LOAN  NOTES.  Construction  Loan  Notes  are  sold to  provide
    construction  financing.  Permanent  financing,  the  proceeds  of which are
    applied to the payment of Construction Loan Notes, is sometimes  provided by
    a commitment by the Government  National  Mortgage  Association  ("GNMA") to
    purchase the loan notes,  accompanied by a commitment by the Federal Housing
    Administration to insure mortgage advances  thereunder.  In other instances,
    permanent financing is provided by commitments of banks to purchase the loan
    notes.

    Issues  of  Municipal  COMMERCIAL  PAPER  typically  represent   short-term,
unsecured, negotiable promissory notes. These obligations are issued by agencies
of state and local  governments  to finance  seasonal  working  capital needs of
municipalities  or to provide interim  construction  financing and are paid from
general  revenues of  municipalities  or are refinanced  with long-term debt. In
most cases,  Municipal Commercial Paper is backed by letters of credit,  lending
agreements,  note  repurchase  agreements  or other credit  facility  agreements
offered by banks or other institutions.

WHEN-ISSUED  SECURITIES.  The  Fund  may  purchase  municipal  securities  on  a
when-issued  basis, in which case delivery and payment normally take place 15 to
45 days after the date of the commitment to purchase. The payment obligation and
the interest  rate that will be received on the  municipal  securities  are each
fixed at the time the buyer enters into the  commitment.  Although the Fund will
only purchase a municipal  security on a when-issued basis with the intention of
actually acquiring the securities, the Fund may sell these securities before the
settlement date if it is deemed advisable.

                                      -3-
<PAGE>

    Municipal  securities  purchased on a when-issued  basis and the  securities
held in the Fund 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
similar changes in value,  I.E., both  experiencing  appreciation  when interest
rates decline and  depreciation  when interest  rates rise).  Therefore,  to the
extent the Fund 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 Fund's assets will vary.  Purchasing a
municipal  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  consisting of cash or liquid  high-grade debt securities
equal to the amount of the when-issued  commitments will be established with the
Custodian  and  marked to market  daily,  with  additional  cash or liquid  debt
securities  added when  necessary.  When the time  comes to pay for  when-issued
securities, the Fund will meet its obligations from then available cash, sale of
securities held in the separate  account,  sale of other securities or, although
it would  not  normally  expect  to do so,  sale of the  when-issued  securities
themselves  (which may have a value  greater or lesser  than the Fund's  payment
obligations).  Sale of  securities  to meet such  obligations  carries with it a
potential for the realization of capital gain,  which is not exempt from federal
or North Carolina income taxes.

FLOATING RATE AND VARIABLE RATE SECURITIES.  The Fund may purchase floating rate
and  variable  rate  securities,   including  participation  interests  therein.
Investments  in floating or  variable  rate  securities  normally  will  involve
industrial  development or revenue bonds which provide that the rate of interest
is set as a specific  percentage  of a  designated  base rate,  such as rates on
Treasury Bonds or Bills or the prime rate at a major  commercial  bank, and that
the Fund can  demand  payment  of the  obligations  on short  notice at par plus
accrued interest, which amount may be more or less than the amount the Fund paid
for them.  Variable rate securities provide for a specified periodic  adjustment
in the interest rate, while floating rate securities have an interest rate which
changes  whenever  there is a  change  in the  designated  base  interest  rate.
Frequently  such  securities  are  secured by letters of credit or other  credit
support  arrangements  provided by banks. The quality of the underlying creditor
or of the bank,  as the case may be, must be  equivalent  to the  standards  set
forth with respect to taxable investments on page 5.

STAND-BY COMMITMENTS.  Under a stand-by commitment,  the Fund obligates a dealer
to repurchase at the Fund's option  specified  securities at a specified  price.
The exercise of a stand-by commitment is subject to the ability of the dealer to
make payment on demand.  The Fund would acquire stand-by  commitments  solely to
facilitate portfolio liquidity and not for trading purposes.  Prior to investing
in stand-by commitments the Fund, if it deems necessary based upon the advice of
counsel,  will apply to the Securities and Exchange  Commission for an exemptive
order relating to such  commitments and the valuation  thereof.  There can be no
assurance that the Securities and Exchange Commission will issue such an order.

    The price which the Fund would pay for  municipal  securities  with stand-by
commitments  generally  would be higher than the price which  otherwise would be
paid for the municipal securities alone. The Fund will only purchase obligations
with stand-by commitments from sellers the Manager deems creditworthy.

    Stand-by  commitments with respect to portfolio  securities of the Fund with
maturities of less than 60 days which are separate from the underlying portfolio
securities are not assigned a value. The cost of any such stand-by commitment is
carried as an unrealized loss from the time of purchase until it is exercised or
expires.  Stand-by  commitments with respect to portfolio securities of the Fund
with  maturities  of 60 days or more  which  are  separate  from the  underlying
portfolio  securities and the underlying portfolio securities are valued at fair
value as determined in accordance  with  procedures  established by the Board of
Trustees.  The Board of Trustees would, in connection with the  determination of
the value of such a  stand-by  commitment,  consider  among  other  factors  the
creditworthiness of the writer of the stand-by  commitment,  the duration of the
stand-by commitment, the dates on which or the periods during which the stand-by
commitment  may be exercised and the  applicable  rules and  regulations  of the
Securities and Exchange Commission.

TAXABLE  INVESTMENTS.  Under normal market conditions,  the Fund will attempt to
invest  100% and as a matter of  fundamental  policy will invest at least 80% of
the value of its net assets in  securities  the interest on which is exempt from
regular federal and North Carolina personal income tax. Such interest,  however,
may be subject to the  federal  alternative  minimum  tax.  However in  abnormal
market conditions,  if, in the judgment of the Manager, the municipal securities
satisfying the Fund's investment objectives may not be purchased,  the Fund may,
for defensive  purposes  temporarily invest in instruments the interest 

                                      -4-
<PAGE>

on which is exempt from regular  federal  income taxes,  but not North  Carolina
personal  income taxes.  Such  securities  would include those  described  under
"North Carolina Municipal Securities" above that would otherwise meet the Fund's
objectives.

    Also,  in  abnormal  market  conditions,  the Fund may invest on a temporary
basis in fixed-income  securities,  the interest on which is subject to federal,
state or local income taxes, pending the investment or reinvestment in municipal
securities of proceeds of sales of shares or sales of portfolio  securities,  in
order to avoid  the  necessity  of  liquidating  portfolio  investments  to meet
redemption  of shares by  investors  or where  market  conditions  due to rising
interest  rates  or  other  adverse  factors  warrant  temporary  investing  for
defensive  purposes.  Investments in taxable securities will be substantially in
securities  issued or guaranteed by the United States Government (such as bills,
notes and bonds), its agencies,  instrumentalities or authorities;  highly-rated
corporate debt securities (rated AA-, or better, by Standard & Poor's or Aa3, or
better, by Moody's); prime commercial paper (rated A-1+/A-1 by Standard & Poor's
or P-1 by  Moody's);  and  certificates  of deposit of the 100 largest  domestic
banks in terms of assets which are subject to regulatory supervision by the U.S.
Government  or state  governments  and the 50 largest  foreign banks in terms of
assets  with  branches  or  agencies  in  the  United  States.   Investments  in
certificates of deposit of foreign banks and foreign  branches of U.S. banks may
involve  certain  risks,  including  different  regulation,   use  of  different
accounting  procedures,  political  or  other  economic  developments,  exchange
controls, or possible seizure or nationalization of foreign deposits.

PORTFOLIO  TURNOVER.  Portfolio  transactions will be undertaken  principally to
accomplish  the Fund's  objective  in relation to  anticipated  movements in the
general  level of  interest  rates but the Fund may also  engage  in  short-term
trading consistent with its objective. Securities may be sold in anticipation of
a market decline (a rise in interest  rates) or purchased in  anticipation  of a
market  rise (a decline  in  interest  rates) and later  sold.  In  addition,  a
security  may be sold and another  purchased at  approximately  the same time to
take advantage of what the Manager  believes to be a temporary  disparity in the
normal yield relationship between the two securities.

   
    The Fund's investment  policies may lead to frequent changes in investments,
particularly  in periods  of rapidly  fluctuating  interest  rates.  A change in
securities held by the Fund is known as "portfolio turnover" and may involve the
payment by the Fund of dealer  spreads or  underwriting  commissions,  and other
transaction costs, on the sale of securities,  as well as on the reinvestment of
the proceeds in other securities.  Portfolio  turnover rate for a fiscal year is
the ratio of the lesser of  purchases or sales of  portfolio  securities  to the
monthly average of the value of portfolio securities.  Securities whose maturity
or expiration date at the time of acquisition were one year or less are excluded
from the  calculation.  The  portfolio  turnover rate for the fiscal years ended
September  30,  1997  and 1996  were  13.04%  and  15.12%,  respectively.  It is
estimated that the portfolio turnover rate of the Fund will not exceed 100%. The
Fund's portfolio turnover rate will not be a limiting factor when the Fund deems
it desirable to sell or purchase securities.
    

                             INVESTMENT LIMITATIONS

    Under the Fund's  fundamental  policies,  which cannot be changed  except by
vote of a majority of the  outstanding  voting  securities of the Fund, the Fund
may not:

- -  Borrow  money,  except  from banks for  temporary  purposes  (such as meeting
   redemption  requests or for  extraordinary or emergency  purposes but not for
   the purchase of portfolio  securities)  in an amount not to exceed 10% of the
   value of its total assets at the time the  borrowing  is made (not  including
   the  amount  borrowed).  The Fund  will  not  purchase  additional  portfolio
   securities  if the Fund has  outstanding  borrowings  in  excess of 5% of the
   value of its total assets;

- -  Mortgage or pledge any of its assets,  except to secure permitted  borrowings
   noted above;

- -  Invest  more than 25% of total  assets at market  value in any one  industry;
   except that municipal securities and securities of the U.S.  Government,  its
   agencies and instrumentalities are not considered an industry for purposes of
   this limitation.

- -  As to 50% of the value of its total assets, purchase securities of any issuer
   if immediately  thereafter more than 5% of total assets at market value would
   be invested in the securities of any issuer (except that this limitation does
   not apply to obligations issued or guaranteed as to principal and interest by
   the U.S. Government or its agencies or instrumentalities);

                                      -5-
<PAGE>

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

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

- -  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  issuer  own in the  aggregate  more than 5% of such
   securities;

- -  Write or purchase put, call, straddle or spread options;  purchase securities
   on margin or sell "short";  or underwrite  the  securities of other  issuers,
   except  that the Fund may be deemed an  underwriter  in  connection  with the
   purchase and sale of portfolio securities;

- -  Purchase  or  sell  commodities  or  commodity  contracts  including  futures
   contracts; or

- -  Make loans,  except to the extent that the purchase of notes,  bonds or other
   evidences of indebtedness or deposits with banks may be considered loans.

    As a matter of policy,  with respect to 75% of the Fund's assets, no revenue
bond will be purchased by the Fund if as a result of such  purchase more than 5%
of the Fund's  assets would be invested in the  securities  of a single  issuer.
This  policy is not  fundamental  and may be  changed  by the  Trustees  without
shareholder approval.

    Under  the  1940  Act,  a "vote  of a  majority  of the  outstanding  voting
securities"  of the Trust or of a  particular  series of the Trust,  such as the
Fund,  means  the  affirmative  vote of the  lesser  of (1) more than 50% of the
outstanding  shares of the Trust or of a series or (2) 67% or more of the shares
of the Trust or of a series present at a shareholders'  meeting if more than 50%
of the  outstanding  shares of the Trust or of a series are  represented  at the
meeting in person or by proxy.

(d)  Deferred.

   
    The Trust has a compensation  arrangement  under which outside  Trustees may
elect to defer receiving their fees. Under this arrangement, interest is accrued
on the deferred balances.  The annual cost of such fees and interest is included
in the  trustees'  fees and expenses,  and the  accumulated  balance  thereof is
included in "Liabilities" in the Fund's financial  statements.  The total amount
of deferred compensation (including interest) payable in respect of the Trust to
Mr.  Whitson as of September 30, 1997 was $13,448.  Messrs.  Merow and Pitney no
longer  defer  current   compensation;   however,  they  have  accrued  deferred
compensation in the amounts of $39,026 and $28,133 as of September 30, 1997. The
Fund has applied for and received  exemptive relief that would permit a director
who has elected  deferral of his or her fees to choose a rate of return equal to
either (i) the interest rate on short-term  Treasury  bills, or (ii) the rate of
return on the shares of any of the investment  companies advised by the manager,
as designated by the director.  The Fund may, but is not obligated to,  purchase
shares of such investment  companies to hedge its obligations in connection with
this deferral arrangement.
    

    Trustees and officers of the Trust are also trustees, directors and officers
of some or all of the other investment companies in the Seligman Group.

   
    No Trustees  or officers of the Fund owned  shares of the Fund at January 2,
1998.

                             MANAGEMENT AND EXPENSES

    Under the Management Agreement,  dated June 21, 1990, subject to the control
of the Trustees,  the Manager  manages the investment of the assets of the Fund,
including making purchases and sales of portfolio securities consistent with the
Fund's  investment  objectives and policies,  and  administers  its business and
other  affairs.   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 Trust 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 the Fund calculated
daily and payable  monthly equal to .50% of the Fund's  average daily net assets
on an annual  basis.  During the fiscal years ended  September 30, 1995 and 1996
the  Manager,  in its  discretion,  waived  all or a portion of its fee from the
Fund, and in some cases also elected to reimburse the Fund for certain  expenses
incurred  during the periods.  For the fiscal year ended September 30, 1997, the
Management fee amounted to $176,659 or .50% of the Fund's average net assets.
    

    The Fund pays all its  expenses  other  than those  assumed  by the  Manager
including  brokerage  commissions,  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 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 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 Trust's  expenses are
allocated  between  each  series  of the  Trust  in a manner  determined  by the
Trustees to be fair and equitable.

    The Fund's  Management  Agreement  was approved by the Trustees at a meeting
held on June 12, 1990, and was  unanimously  approved by the  shareholders  at a
meeting  held on April 11, 1991.  The  Agreement  will  continue in effect until
December  29 of each year if (1) such  continuance  is  approved  in the  manner
required by the 1940 Act (i.e.,  by a vote of a majority  of the  Trustees or of
the outstanding voting securities of the Fund 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) the Manager shall not have notified the Fund at least
60  days  prior  to  December  29 of any  year  that  it does  not  desire  such
continuance. The Agreement may be terminated by the Fund, without penalty, on 60
days'  written  notice to the Manager and will  terminate  automatically  in the
event of its assignment. The Fund 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 Appendix
B 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  Compliance  Officer,  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
Compliance  Officer,  or (vi) is being  acquired  during an initial or 
    
                                      -11-

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 PLAN

    As indicated in the Prospectus, an Administration,  Shareholder Services and
Distribution  Plan (the  "Plan")  for the Fund  will be in effect  from the date
hereof under Section 12(b) of the 1940 Act and Rule 12b-1 thereunder.

    The Plan was approved on June 21, 1990 by the Trustees, including a majority
of the Trustees who are not "interested persons" (as defined in the 1940 Act) of
the Fund and who have no direct or indirect  financial interest in the operation
of the Plan or in any agreement  related to the Plan (the "Qualified  Trustees")
and on April 11, 1991 by the  shareholders  of the Fund.  Amendments to the Plan
were  approved  in respect  of the Class D shares on  November  18,  1993 by the
Trustees,  including a majority of the Qualified Trustees,  and became effective
with respect to the Class D shares on February 1, 1994.  The Plan will  continue
in effect until December 31 of each year so long as such continuance is approved
annually by a majority vote of both the 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 with respect to a class of shares without the approval
of a majority of the outstanding  voting securities of the Class and no material
amendment  to the Plan may be made except by a majority of both the Trustees and
the Qualified Trustees.

    The Plan  requires  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)  under the Plan.  Rule 12b-1 also
requires that the selection and  nomination of Trustees who are not  "interested
persons" of the Trust be made by such disinterested Trustees.

                             PORTFOLIO TRANSACTIONS

   
    No brokerage commissions were paid by the Fund during the fiscal years ended
September 30, 1997, 1996 or 1995. When the Fund or 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  already  obtainable
or saleable.
    

                     PURCHASE AND REDEMPTION OF FUND SHARES

    The Fund issues two classes of shares:  Class A shares may be purchased at a
price equal to the next determined net asset value per share, plus a 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 of 1% if such shares are redeemed
within eighteen  months 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 certain  redemptions  within one year of purchase.  See
"Alternative  Distribution  System,"  "Purchase of Shares," and  "Redemption  of
Shares" in the Fund's Prospectus.

SPECIMEN PRICE MAKE-UP

    Under  the  current  distribution  arrangements  between  the  Trust and the
Distributor,  Class A shares are sold at a maximum sales load of 4.75% and Class
D shares  are sold at net asset  value.*  Using the  Fund's  net asset  value at
September  30,  1997,  the  maximum  offering  price of the Fund's  shares is as
follows:

    CLASS A

   
     Net asset value per share....................................        $ 8.05

- ---------
*    Class D shares are subject to a CDSL of 1% on  redemptions  within one year
     of purchase. Class A shares purchased at net asset value due to the size of
     the  purchase  are subject to a CDSL of 1% on  redemption  within  eighteen
     months of  purchase  of such  shares.  See  "Redemption  of  Shares" in the
     Prospectus.
    

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 the Fund alone, the other series of the Trust 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 the Prospectuses.

   
     THE RIGHT OF  ACCUMULATION  allows an investor to combine the amount  being
invested in Class A shares of the Fund, the other series of the Trust and shares
of other  Seligman  Mutual Funds sold with an initial  sales load with the total
net asset value of shares of those other  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  Seligman Mutual Fund on which there was an initial sales load at the
time of  purchase  to  determine  reduced  sales  loads in  accordance  with the
schedule in the Prospectuses. The value of the shares owned, including the value
of shares of Seligman Cash  Management Fund acquired in an exchange of shares of
another Seligman Mutual Fund on which there 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 the
investor or a dealer of the amount owned 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 the
Fund over a 13-month  period at reduced  initial sales loads in accordance  with
the  schedule in the  Prospectuses,  based on the total amount of Class A shares
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 series of
the Trust and other Seligman  Mutual Funds already owned and the total net asset
value of shares of Seligman Cash Management Fund which were acquired  through an
exchange of shares of another Seligman Mutual Fund on which there was an initial
sales load at the time of purchase.  Reduced  initial 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 -
Class A shares" in the Fund's Prospectus.
    

                                      -13-
<PAGE>

     Class A shares  purchased  without an initial sales load in accordance with
the sales  load  schedule  in the 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 sales loads apply to purchases of
Class A shares  of the  Fund 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 (the "Code),  tax-exempt  organizations  under  Section 501 (c)(3) or
(13) of the Code, and non-qualified  employee benefit plans that satisfy uniform
criteria are considered "single persons" for this purpose.  The uniform criteria
are as follows:

1.  Employees must authorize the employer,  if requested by the Fund, to receive
    in bulk and to  distribute  to each  participant  on a timely basis the Fund
    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 the  Prospectus
applies  to sales to  "eligible  employee  benefit  plans"  (as  defined  in the
Prospectus),  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  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 funding or other systems  acceptable to Seligman Data Corp.,  the
Trust'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.

   
FURTHER  TYPES OF  REDUCTIONS.  Class A shares 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  financial
institution trust  departments,  to registered  investment  advisers  exercising
investment  discretionary 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 financial  institution  trust
departments;   to  registered   investment  advisers  exercising   discretionary
investment authority with respect to the purchase of Fund 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 Fund;
to  other  investment  companies  in the  Seligman  Group in  connection  with a
deferred  fee  arrangement  for outside  directors;  and to  "eligible  employee
benefit plans" which have at least (i) $500,000  invested in the Seligman 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 Fund shares.  Sales of shares
to such plans must be made in connection with a payroll deduction system of plan
funding or other system acceptable to Seligman Data Corp.
    

    Class A  shares  may be sold at net  asset  value  to  present  and  retired
Trustees, directors,  officers, employees (and family members, as defined in the
Prospectus) of the Fund, the other  investment  companies in the Seligman Group,
the Manager and other companies affiliated with the Manager. Such sales also may
be made to  employee  benefit  plans  for  such  persons  and to 

                                      -14-
<PAGE>

any investment advisory,  custodial, trust or other fiduciary account managed or
advised by the Manager 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.

PAYMENT IN SECURITIES.  In addition to cash,  the Fund may accept  securities in
payment for Fund shares sold at the applicable public offering price. Generally,
the Fund will only consider accepting securities (1) to increase its holdings in
a portfolio  security of the Fund,  or (2) if the  Manager  determines  that the
offered  securities  are  a  suitable  investment  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  with  securities,  may  require  partial  payment  in cash  for
applicable sales loads, and may discontinue  accepting securities as payment for
shares  at any  time  without  notice.  The  Fund has no  present  intention  of
accepting securities in payment for shares.

MORE ABOUT  REDEMPTIONS.  The  procedures  for  redemption  of Fund shares under
ordinary  circumstances are set forth in the Prospectus.  Payment may be made in
securities or postponed,  if the orderly liquidation of portfolio  securities is
prevented  by the  closing  of, or  restricted  trading  on,  the New York Stock
Exchange during periods of emergency, or during such other periods as ordered by
the  Securities  and  Exchange  Commission.  If  payment  were  to  be  made  in
securities,  shareholders  receiving  securities could incur certain transaction
costs.  The  Fund  will  not  accept  orders  from  securities  dealers  for the
repurchase of shares.

                              DISTRIBUTION SERVICES

    SFSI, an affiliate of the Manager, acts as general distributor of the shares
of the Trust and of the other  mutual funds in the  Seligman  Group.  As general
distributor  of  the  Trust's  shares  of  beneficial   interest,   SFSI  allows
commissions  to all  dealers  of up to 4.25% on  purchases  of Class A shares to
which the 4.75% sales load applies. SFSI receives the balance of sales loads and
any CDSL, if applicable,  paid by investors. The Trust and SFSI are parties to a
Distributing Agreement dated January 1, 1993.

   
    The total  sales load paid by  shareholders  of the Fund for the fiscal year
ended  September 30, 1997  amounted to $51,778,  with an allowance of $45,457 as
commissions to dealers; for the fiscal year ended September 30, 1996 amounted to
$104,210, with an allowance of $91,647 as commissions to dealers; for the fiscal
year ended  September 30, 1995 amounted to $130,611,  with allowance of $115,498
as  commissions  to dealers.  For the years ended  September 30, 1997,  1996 and
1995, SFSI retained CDSL charges amounting to $0, $5 and $276, respectively.

    Effective April 1, 1995,  Seligman Services,  Inc. ("SSI"),  an affiliate of
the Manager,  became eligible to receive  commissions from certain sales of Fund
shares,  as well as distribution  and service fees pursuant to the Plan. For the
years ended  September 30, 1997 and 1996, and for the period ended September 30,
1995, SSI received commission of $0, $171 and $85,  respectively,  from sales of
Fund shares. SSI also received  distribution and service fees of $1,858,  $1,638
and $743, respectively, pursuant to the Plan.
    

                                      TAXES

   
    Under the Code,  each  Series of the Trust  will be  treated  as a  separate
corporation for federal income tax purposes. As a result,  determinations of net
investment  income,  exempt interest  dividends and net long-term and short-term
capital gain and loss will be made separately for each Series.

    The  Fund  intends  to  qualify  and  elect  to be  treated  as a  regulated
investment  company under the Code and thus to be relieved of federal income tax
on amounts  distributed to  shareholders;  provided that it distributes at least
90% of its net investment income and net short-term capital gains, if any.
    

                                      -15-
<PAGE>

   
    Qualification  as a regulated  investment  company  under the Code  requires
among  other  things,  that (a) at least 90% of the annual  gross  income of the
Trust, be derived from dividends,  interest, payments with respect to securities
loans and gains  from the sale or other  disposition  of stocks,  securities  or
currencies,  or other income  (including  but not limited to gains from options,
futures,  and  forward  contracts)  derived  with  respect  to its  business  of
investing in such stocks, securities or currencies; and (b) the Fund diversifies
its  holdings so that,  at the end of each quarter of the taxable  year,  (i) at
least 50% of the  market  value of the  Fund's  assets is  represented  by cash,
United States Government  securities and other securities  limited in respect of
any one issuer to an amount not greater than 5% of the Fund's  assets and 10% of
the outstanding  voting securities of such issuer, and (ii) not more than 25% of
the value of its assets is invested in the  securities  of any one issuer (other
than U.S. Government securities).
    

                                    VALUATION

   
    The net asset value per share of each class of the Fund is  determined as of
the close of regular trading on the New York Stock Exchange ("NYSE")  (normally,
4:00 p.m. Eastern time) on each day that the NYSE is open. The Fund and the NYSE
are currently closed on New Year's Day, Martin Luther King, Jr. Day, Presidents'
Day, Good Friday,  Memorial Day,  Independence Day, Labor Day, Thanksgiving Day,
and  Christmas  Day. The Fund will also  determine net asset value per share for
each class on each day in which there is a  sufficient  degree of trading in the
Fund's  portfolio  securities  that the net asset value of Fund shares  might be
materially  affected.  Net asset  value per  share  for a class is  computed  by
dividing such class' share of the value of the net assets of the Fund (i.e., the
value of its assets less liabilities) by the total number of outstanding  shares
of such class.  All  expenses of the Fund,  including  the  Manager's  fee,  are
accrued  daily and taken into account for the purpose of  determining  net asset
value.  The net asset value of Class D shares will  generally  be lower than the
net asset  value of Class A shares as a result of the  higher  distribution  fee
with  respect to Class D shares.  It is  expected,  however,  that the net asset
value per share of the two classes will tend to converge  immediately  after the
recording of  dividends,  which will differ by  approximately  the amount of the
distribution and other class expenses accrual differential between the classes.
    

    North  Carolina  municipal  securities  will  be  valued  on  the  basis  of
quotations provided by an independent pricing service, approved by the Trustees,
which uses  information  with respect to transactions in bonds,  quotations from
bond  dealers,   market  transactions  in  comparable   securities  and  various
relationships  between  securities in determining  value. In the absence of such
quotations, fair value will be determined in accordance with procedures approved
by the Trustees. Short-term notes having remaining maturities of 60 days or less
are generally valued at amortized cost.

    Generally,  trading  in certain  securities  such as  municipal  securities,
corporate bonds, U.S.  Government  securities,  and money market  instruments is
substantially  completed  each day at  various  times  prior to the close of the
NYSE. The values of such  securities  used in determining the net asset value of
the Fund's shares are computed as of such times. Occasionally,  events affecting
the value of such  securities  may occur between such times and the close of the
NYSE  which will not be  reflected  in the  computation  of the Fund's net asset
value. If events materially  affecting the value of such securities occur during
such period, then these securities and other assets will be valued at their fair
market value as determined in good faith by the Trustees.

                             PERFORMANCE INFORMATION

   
    The annualized  yield for the 30-day period ended September 30, 1997 for the
Fund's Class A shares was 4.05%.  The annualized  yield was computed by dividing
the Fund's net investment  income per share earned during a 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 September 30, 1997, the last
day of the  period.  The  average  number of Class A shares of the Fund used was
4,100,176  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  (which  includes  fees  charged  pursuant to the Fund's 12b-1
plan). 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 the Prospectus.

    The tax equivalent  annualized  yield for the 30-day period ended  September
30, 1997 for the Fund's Class A shares was 7.27%. The tax equivalent  annualized
yield was computed by first computing the annualized  yield as discussed  above.
Then the portion of the yield attributable to securities the income of which was
exempt for federal and state income tax purposes was determined. This portion of
the yield was then divided by one minus 44.28% (44.28% being the assumed maximum
combined federal and state income tax rate for individual  taxpayers  subject to
North  Carolina  personal  income  taxes).  Then the small  portion of the yield
attributable  to  securities,  the income of which was exempt  only for  federal
income tax purposes was  determined.  This portion of the yield was then divided
by one minus 39.6% (39.6% being the maximum federal income tax rate).  These two
calculations  were then added to the portion of the yield,  if any, that was not
attributable to securities, the income of which was not tax exempt.

    The  average  annual  total  return  for the  Fund's  Class A shares for the
one-year  period ended  September 30, 1997 was 2.89%,  for the five-year  period
ended September 30, 1997 was 5.72%, and since inception through the period ended
September  30,  1997 was  6.77%.  These  returns  were  computed  by  assuming a
hypothetical initial payment of $1,000. From this $1,000, the maximum sales load
of $47.50 (4.75% of public  offering  price) was  deducted.  It was then assumed
that all of the dividends and distributions  paid by the Class A shares over the
relevant  time period were  reinvested.  It was then  assumed that at the end of
each of the above  periods,  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 annualized  yield for the 30-day period ended September 30, 1997 for the
Fund's Class D shares was 3.50%.  The annualized  yield was computed by dividing
the net  investment  income per share  earned  during this 30-day  period by the
maximum  offering  price per share (i.e.,  the net asset value) on September 30,
1997,  which  was the last day of this  period.  The  average  number of Class D
shares was 157,610  which was the  average  daily  number of shares  outstanding
during the 30-day period that were eligible to receive dividends.

    The tax equivalent  annualized  yield for the 30-day period ended  September
30, 1997 for the Fund's Class D shares was 6.28%. The tax equivalent  annualized
yield was computed by first computing the annualized  yield as discussed  above.
Then the portion of the yield attributable to securities the income of which was
exempt for federal and state income tax purposes was determined. This portion of
the yield was then divided by one minus  44.28%,  which  percentages  assume the
maximum combined federal and state income tax rate for individual taxpayers that
are subject to such personal income taxes.

    The average  annual  return for the Fund's  Class D shares for the  one-year
period ended September 30, 1997 was 6.33% and since inception through the period
ended  September  30, 1997 was 4.04%.  These returns were computed by assuming a
hypothetical  initial  payment  of $1,000 in Class D shares  and that all of the
dividends and  distributions by the Fund's Class D shares over the relevant time
period were reinvested.  It was then assumed that at the end of each period, the
entire amount was redeemed, subtracting the 1% CDSL, if applicable.
    

    The tables below  illustrate  the total  returns on a $1,000  investment  in
Class A and Class D shares of the Fund from the commencement of their operations
through  September  30, 1997,  assuming  investment of all dividends and capital
gain distributions.

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

    gain distributions.
    

3   Total return for the Fund is calculated by assuming a  hypothetical  initial
    investment of $1,000 at the beginning of the period  specified,  subtracting
    the maximum sales load or CDSL, if  applicable;  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; and finally, by dividing the difference
    between the amount of the hypothetical  initial  investment at the beginning
    of the  period  and its  value at the end of  period  by the  amount  of the
    hypothetical initial investment.

    The  waiver  by the  Manager  of all of its  fees and the  reimbursement  of
certain Fund  expenses  during the periods (as set forth under  "Management  and
Expenses " herein  and  "Financial  Highlights"  in the  Prospectus)  positively
affected the performance results provided in this section.

                               GENERAL INFORMATION

    The Trustees are  authorized to classify or reclassify  and issue any shares
of  beneficial  interest of the Trust into any number of other  classes  without
further action by  shareholders.  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.

    As a general matter, the Trust 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 Trust or any series, including the Fund, 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 Trust 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 Code, 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

                                      -18-
<PAGE>

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  Trust or the  shareholders,  and (f)  with  respect  to such  additional
matters  relating  to the  Trust  as may  be  required  by  the  1940  Act,  the
Declaration of Trust,  the By-laws of the Trust,  any  registration of the Trust
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 Trust  have the  right,  upon the  declaration  in
writing or vote of more than two-thirds of the Trust'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 Trustee  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 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  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
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  to be
submitted  by the  provisions  of the  1940  Act or  applicable  state  law,  or
otherwise,  to the holders of the outstanding voting securities of an investment
company  such as the Trust  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 each 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  public  accountants,  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,  801 Pennsylvania,  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 value 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, NY

    RISK FACTORS REGARDING INVESTMENTS IN NORTH CAROLINA MUNICIPAL SECURITIES

   
    While North Carolina has been moving from an  agricultural  to a service and
goods producing economy in recent years,  agriculture remains a basic element in
the economy of North Carolina,  with tobacco production being the leading single
source of agricultural  income.  Although there is diversity in the agricultural
business in North Carolina,  major legislative or regulatory  measures affecting
the  production  and marketing of tobacco or other  negative  factors  affecting
tobacco could  adversely  impact the  agricultural  sector of the North Carolina
economy.  A strong  agribusiness  sector also supports  farmers with farm inputs
(fertilizer,  insecticide,  pesticide  and farm  machinery)  and  processing  of
commodities produced by farmers (vegetable canning and cigarette manufacturing).
Manufacturing,  tourism and mining also remain important to the State's economy.
North Carolina's manufacturing employment is among the largest in the Southeast,
with textiles  being the largest  single source of  manufacturing  employment in
North Carolina.  However,  certain portions of the North Carolina  manufacturing
sector, particularly the textile industry, have been hurt by foreign competition
and textiles and apparel continue to experience  declines.  Tourist spending has
become a larger factor in the North Carolina economy in recent years. While most
sectors of the North Carolina  economy,  excluding  textiles,  have  experienced
growth in the last few years, the rate of future growth is expected to be slowed
by a limited increase in available new labor. In fact, while continued  economic
growth for North  Carolina  is  projected  for 1998,  the rate of that growth is
forecast to slow  statewide and in most regions of the State. A major reason for
the expected  slower growth is a reduction in retail sales growth  together with
slower residential construction.

    The North Carolina State  Constitution  requires that the total expenditures
of the State for each  fiscal  period  covered by the budget must not exceed the
total receipts during the fiscal period and the surplus in the State Treasury at
the beginning of the period.  During the State's  1990-1991  fiscal year,  North
Carolina began facing a substantial budget shortfall  resulting from the failure
of revenues received by the State to meet projected levels.  While the State was
successful  in dealing with the problem,  pressure on State  revenues will be an
ongoing  problem.  Because of taxpayer  litigation  concerning  the now repealed
intangibles  tax, North Carolina is facing having to pay a multi-million  dollar
tax refund of the  intangibles  tax for certain  years.  The State has set aside
certain funds in anticipation of having to pay these refunds.
    

    General  obligations of the State are currently rated "AAA" and "Aaa" by S&P
and  Moody's,  respectively.  There  can  be  no  assurance  that  the  economic
conditions  on which these  ratings are based will  continue or that  particular
bond issues may not be adversely  affected by changes in economic,  political or
other  conditions,  including the State's response to any future budget problem.
When the budget shortfall  problem first  developed,  the State was cautioned by
S&P and Moody's  that a failure to respond  adequately  to the budget  shortfall
could  result in a  reevaluation  of the ratings  given to the  State's  general
obligations  and the State's  response  to any future  budget  problems  will be
important to the  maintenance  of its current  ratings.  Moreover,  such ratings
apply  only to  obligations  of the  State  and not to  those  of its  political
subdivisions, and the economic information provided above may not be relevant to
obligations issued by such political subdivisions.

                              FINANCIAL STATEMENTS

   
  The Annual Report to Shareholders for the fiscal year ended September 30, 1997

MOODY'S INVESTORS SERVICE, INC. ("MOODY'S")
MUNICIPAL BONDS

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

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

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

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

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

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

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

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

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

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

MUNICIPAL NOTES

  Moody's ratings for municipal notes and other  short-term loans are designated
Moody's  Investment  Grade (MIG).  This  distinction  is in  recognition  of the
differences  between  short-term  and long-term  credit risk.  Loans bearing the
designation  MIG 1 are  of the  best  quality,  enjoying  strong  protection  by
established  cash  flows of funds  for their  servicing  or by  established  and
broad-based access to the market for refinancing.  Loans bearing the designation
MIG 2 are of high  quality,  with margins of  protection  ample  although not so
large as in the  preceding  group.  Loans bearing the  designation  MIG 3 are of
favorable  quality,  with all security  elements  accounted  for but lacking the
undeniable  strength of the preceding  grades.  Market access for refinancing in
particular, is likely to be less well established. Notes bearing the designation
MIG 4 are 

                                      -21-
<PAGE>

judged to be of adequate  quality,  carrying specific risk but having protection
commonly  regarded as required of an investment  security and not  distinctly or
predominantly speculative.

COMMERCIAL PAPER

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

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

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

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

STANDARD & POOR'S CORPORATION ("S&P")
MUNICIPAL BONDS

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

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

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

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

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

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

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

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

                                      -22-
<PAGE>

MUNICIPAL NOTES

  SP-1:  Very strong or strong  capacity to pay principal  and  interest.  Those
issues determined to possess overwhelming safety characteristics will be given a
plus (+) designation.

  SP-2:  Satisfactory capacity to pay principal and interest.

COMMERCIAL PAPER

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

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

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

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

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

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

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

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

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

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

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

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

THE SELIGMAN COMPLEX:

      York Mutual Gas Light Company, later part of Consolidated Edison.

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

 ...1930s

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

Notes to Financial Statements

1. Multiple Classes of Shares -- Seligman Municipal Series Trust (the "Trust")
consists of four separate series: the "California High-Yield Series," the
"California Quality Series," the "Florida Series," and the "North Carolina
Series." Each Series of the Trust offers two classes of shares. All shares
existing prior to February 1, 1994, the commencement date of Class D shares,
were classified as Class A shares. Class A shares are sold with an initial sales
charge of up to 4.75% and a continuing service fee of up to 0.25% on an annual
basis. Class A shares purchased in an amount of $1,000,000 or more are sold
without an initial sales charge but are subject to a contingent deferred sales
load ("CDSL") of 1% on redemptions within 18 months of purchase. Class D shares
are sold without an initial sales charge but are subject to a distribution fee
of up to 0.75% and a service fee of up to 0.25% on an annual basis, and a CDSL
of 1% imposed on redemptions made within one year of purchase. The two classes
of shares for each Series represent interests in the same portfolio of
investments, have the same rights and are generally identical in all respects
except that each class bears its separate distribution and certain other class
expenses, and has exclusive voting rights with respect to any matter on which a
separate vote of any class is required.

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

a.  Security Valuation -- All municipal securities and other short-term holdings
    maturing in more than 60 days are valued based upon quotations provided by
    an independent pricing service or, in their absence, at fair value
    determined in accordance with procedures approved by the Trustees.
    Short-term holdings maturing in 60 days or less are generally valued at
    amortized cost.

b.  Federal Taxes -- There is no provision for federal income tax. Each Series
    has elected to be taxed as a regulated investment company and intends to
    distribute substantially all taxable net income and net gain realized.

c.  Security Transactions and Related Investment Income -- Investment
    transactions are recorded on trade dates. Identified cost of investments
    sold is used for both financial statement and federal income tax purposes.
    Interest income is recorded on the accrual basis. The Trust amortizes
    original issue discounts and premiums paid on purchases of portfolio
    securities. Discounts other than original
    issue discounts are not amortized.

d.  Multiple Class Allocations -- All income, expenses (other than
    class-specific expenses), and realized and unrealized gains or losses are
    allocated daily to each class of shares based upon the relative value of the
    shares of each class. Class-specific expenses, which include distribution
    and service fees and any other items that are specifically attributable to
    a particular class, are charged directly to such class. For the year ended
    September 30, 1997, distribution and service fees were the only
    class-specific expenses.

e.  Distributions to Shareholders -- Dividends are declared daily and paid
    monthly. Other distributions paid by the Trust are recorded on the
    ex-dividend date. The treatment for financial statement purposes of
    distributions made to shareholders during the year from net investment
    income or net realized gains may differ from their ultimate treatment for
    federal income tax purposes. These differences are caused primarily by
    differences in the timing of the recognition of certain components of
    income, expense, or realized capital gain for federal income tax purposes.
    Where such differences are permanent in nature, they are reclassified in the
    components of net assets based on their ultimate characterization for
    federal income tax purposes. Any such reclassifications will have no effect
    on net assets, results of operations, or net asset value per share of any
    series of the Trust.

3. Purchases and Sales of Securities -- Purchases and sales of portfolio
securities, excluding short-term investments, for the year ended September 30,
1997, were as follows:

  SERIES                    PURCHASES                SALES
- ----------                ------------           ------------

Florida                     15,089,050              18,279,160
North Carolina               4,549,405              10,481,680

    At September 30, 1997, the cost of investments for federal income tax
purposes was substantially the same as the cost for financial reporting
purposes, and the tax basis gross unrealized appreciation and depreciation of
portfolio securities were as follows:

                               TOTAL                  TOTAL
                            UNREALIZED             UNREALIZED

California Quality           5,958,601               30,570
Florida                      1,668,548               82,555

such fees to the Trust pursuant to the Plan. For the year ended September 30,
1997, for the California High-Yield, California Quality, Florida, and North

Class D shares occurring within one year of purchase and on certain redemptions
of Class A shares occurring within 18 months of purchase. For the year ended

Financial Highlights

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

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

Report of Independent Auditors

The Trustees and Shareholders,
Seligman Municipal Series Trust:

We have audited the accompanying statements of assets and liabilities, including
the portfolios of investments, of the California High-Yield, California Quality,
Florida, and North Carolina Series of Seligman Municipal Series Trust, as of
September 30, 1997, the related statements of operations for the year then ended
and of changes in net assets for each of the years in the two-year period then
ended, and the financial highlights for each of the periods presented. These
financial statements and financial highlights are the responsibility of the
Trust's management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements.

Our procedures included confirmation of securities owned as of September 30,
1997 by correspondence with the Trust's custodian and brokers; where replies
were not received from brokers, we performed other auditing procedures. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, such financial statements and financial highlights present
fairly, in all material respects, the financial position of the California
High-Yield, California Quality, Florida, and North Carolina Series of Seligman
Municipal Series Trust as of September 30, 1997, the results of their
operations, the changes in their net assets, and the financial highlights for
the respective stated periods, in conformity with generally accepted accounting
principles.

ITEM 27.     INDEMNIFICATION

   
             Reference is made to the provisions of Article VII of  Registrant's
             Amended and Restated Declaration of Trust filed as Exhibit 24(b)(1)
             and Article VII of Registrant's  Amended and Restated By-Laws filed
             as Exhibit 24(b)(2) to Registrant's Post-Effective Amendment No. 25
             to the Registration Statement.
    

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

Seligman Municipal Series Trust,
100 Park Avenue, 8th Floor,
New York, New York 10017.

Ladies and Gentlemen:

          We have acted as counsel to Seligman Municipal Series Trust (the
"Trust"), and you have requested our opinion regarding the California personal
income tax consequences to holders of certain of the series of shares of
beneficial interest in the Trust.

          The Trust, an unincorporated business trust organized under the laws
of Massachusetts pursuant to a Declaration of Trust (the "Declaration"), is an
open-end, non-diversified management investment company. Article VI of the
Declaration authorizes the issuance of shares or units of beneficial interest in
the Trust. The shares may be divided into series of shares, the proceeds of
which may be invested in separate investment portfolios. Each share in a series
represents a beneficial interest in the net assets of the series, and each
shareholder in a series is entitled to receive such shareholder's pro rata share
of the distributions of income and capital gains with respect to such series.
Upon redemption of a shareholder's shares in a series, the shareholder is paid
solely out of the funds and property of such series, and, upon liquidation or
termination of a series, a shareholder is entitled only to such shareholder's
pro rata share of the net assets of such series.

<PAGE>

          All consideration received by the Trust for the issue or sale of
shares in a series, all assets in which such consideration is invested, and all
income from such assets, including any proceeds derived from the sale, exchange,
or liquidation of such assets, belong to that series, subject only to the rights
of creditors of the series. The assets belonging to each series are charged with
the liabilities attributable to that series only and with all expenses, costs,
charges, and reserves attributable to that series.

          At present, the Trust offers separate investment series, each with
different investment objectives and policies and each composed of different
types of assets and having different shareholders. The Quality Series seeks high
tax-exempt income consistent with preservation of capital and with consideration
given to capital gain by investing in obligations of the state of California and
its political subdivisions the interest on which is exempt from Federal and
California personal income tax ("California tax-exempt securities") rated within
or of quality comparable to the three highest rating categories of Moody's
Investors Service ("Moody's") or Standard & Poor's Rating Service ("S&P"). The
High-Yield Series seeks the maximum amount of tax-exempt income consistent with
preservation of capital and with consideration given to capital gain by
investing primarily in California tax-exempt securities which are rated in the
medium and lower rating categories of Moody's or S&P or which are unrated (the
Quality Series and the High-Yield Series are collectively referred to herein as
"Series").

          It is expected that any further series to be established under the
Declaration and offered by the Trust will have investment objectives and
policies, types of assets, and shareholders that are different from those of the
Series and any other series currently established under the Declaration. Section
6.9 of the Declaration provides that if the Trustees divide shares of the 

<PAGE>


Trust into two or more series of classes, then all provisions of the Declaration
shall apply equally to each series.

          The income of each Series will consist primarily of interest on
California tax-exempt securities, and the balance will consist in part of
interest on certain other securities which is excluded from gross income for
Federal and California personal income tax purposes (Non-California tax-exempt
securities").

          In connection with this opinion we have assumed, with your consent,
that each series of the Trust is a separate regulated investment company taxable
under Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code")
and that dividends paid by each Series will constitute in whole or in part
"exempt-interest dividends" within the meaning of Section 852(b)(5) of the Code.

          On the basis of the foregoing, and our consideration of such matters
as we have considered necessary, we advise you that, in our opinion, for
California personal income tax purposes:

                  (1) Dividends received by a shareholder who is subject to
         California personal income tax are generally includable in California
         gross income. However, dividends received from each Series attributable
         to interest received by the Series during its taxable year on
         California tax-exempt securities and on Non-California tax-exempt
         securities are excludable from California gross income provided that at
         the end of each quarter of its taxable year, at least 50 percent of the
         value of the total assets of the Series consists of such securities.
         Section 17145 of the California Revenue and Taxation Code. Because each
         Series will be treated as a separate regulated investment company, the
         determination under Section 17145 with respect to a Series will be made
         solely on the basis of the 

<PAGE>

         proportion of the value of the total assets of that Series constituting
         California tax-exempt securities and Non-California tax-exempt
         securities.

                  (2) Capital gain dividends of each Series, as defined in
         Section 852(b)(3) of the Code, will be taxed as long-term capital gain
         to a shareholder. Section 17088(a) of the California Revenue and
         Taxation Code.


          We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement for the Trust. In giving such consent we do not thereby
