KEYSTONE STATE TAX FREE FUND
PROSPECTUS MAY 31, 1995
AS SUPPLEMENTED JUNE 1, 1995

  Keystone State Tax Free Fund (formerly  named Keystone  America State Tax Free
Fund) (the  "FUND") is a mutual fund that  currently  consists of five  separate
series of shares  evidencing  interests in different  portfolios  of  securities
("Fund(s)"):  the Keystone Florida Tax Free Fund ("Florida Fund"),  the Keystone
Massachusetts  Tax Free  Fund  ("Massachusetts  Fund"),  the  Keystone  New York
Insured Tax Free Fund ("New York Insured Fund"),  the Keystone  Pennsylvania Tax
Free Fund  ("Pennsylvania  Fund") and the  Keystone  Texas Tax Free Fund ("Texas
Fund").

  Each of the Funds  seeks the  highest  possible  current  income  exempt  from
federal income taxes, while preserving  capital.  In addition,  each Fund, other
than the Florida Fund and the Texas Fund,  also seeks to provide a maximum level
of income to its  shareholders  that is exempt from the personal income taxes of
the state for which such Fund is named.

  The Florida Fund also seeks to hold securities exempt from Florida  intangible
taxes. At the present time, Florida does not impose a personal income tax.

  The New York Insured Fund also seeks to hold  securities  exempt from New York
City personal income tax.

  The Pennsylvania  Fund also seeks to hold securities  exempt from Pennsylvania
property taxes.

  Texas does not  currently  impose a personal  income  tax.  In the event Texas
enacts a personal  income  tax,  the Texas Fund will seek the  highest  possible
current income exempt from such taxes, while preserving capital.

  Each Fund invests  principally  in municipal  obligations  exempt from federal
income tax and municipal  obligations  issued by the state for which it is named
and its political subdivisions, agencies and instrumentalities.  At least 80% of
the  municipal  securities  in the New York  Insured  Fund's  portfolio  will be
insured as to timely payment of both principal and interest.  All securities not
insured by the issuer will be insured by a  qualified  municipal  bond  insurer.
Each Fund's net asset value per share will  fluctuate  in response to changes in
the market value of its portfolio securities.

  Generally,  each Fund offers  three  classes of shares.  Information  on share
classes and their fee and sales  charge  structures  may be found in each Fund's
fee  table,  "How  to Buy  Shares,"  "Alternative  Sales  Options,"  "Contingent
Deferred Sales Charge and Waiver of Sales  Charges,"  "Distribution  Plans," and
"FUND Shares."

<F1> Class B shares purchased on or after June 1, 1995 convert tax free to Class A shares after eight calendar years. See "Class B
     Shares" for more information.
<F2> Class C shares are  available  only  through  dealers who have entered into special  distribution  agreements  with  Keystone
     Investment Distributors Company, the Fund's principal underwriter.
<F3> The sales charge applied to purchases of Class A shares declines as the amount invested  increases.  See  "Alternative  Sales
     Options."
<F4> Purchases of Class A shares in the amount of $1,000,000 or more and/or  purchases  made by certain  qualifying  retirement or
     other plans are not subject to a sales charge, but may be subject to a contingent deferred sales charge. See "Class A Shares"
     and "Contingent Deferred Sales Charge and Waiver of Sales Charges" for an explanation of the charge.
<F5> There is no fee for  individual  investors  making  exchanges  over the Keystone  Automated  Response Line  ("KARL").  (For a
     description of KARL, see "Shareholder Services.")
<F6> Expense ratios are for the fiscal year ended March 31, 1995 after giving effect to the  reimbursement by Keystone  Investment
     Management Company ("Keystone") of expenses in accordance with certain voluntary expense limitations. Currently, Keystone has
     voluntarily  limited  expenses of Class A Shares to 0.75% of average  daily net assets until  December  31, 1995.  Similarly,
     Keystone has  voluntarily  limited  expenses of Class B and C shares to 1.50% of average  daily net assets of each such class
     until December 31, 1995.  Keystone is under no obligation to maintain these limits.  Absent  voluntary  expense  limitations,
     expense ratios for the fiscal year ended March 31, 1995 for the Florida Fund's Class A, B and C shares,  respectively,  would
     have been 0.95%, 1.68%, and 1.70%.
<F7> Long term  shareholders may pay more than the economic  equivalent of the maximum front end sales charges  permitted by rules
     adopted by the National Association of Securities Dealers, Inc. ("NASD").
<F8> The Securities and Exchange Commission requires use of a 5% annual return figure for purposes of this example. Actual returns
     for the Funds may be greater or less than 5%.

<F1> Class B shares purchased on or after June 1, 1995 convert tax free to Class A shares after eight calendar years. See "Class B
     Shares" for more information.
<F2> Class C shares are  available  only  through  dealers who have entered into special  distribution  agreements  with  Keystone
     Investment Distributors Company, the Fund's principal underwriter.
<F3> The sales charge applied to purchases of Class A shares declines as the amount invested  increases.  See  "Alternative  Sales
     Options."
<F4> Purchases of Class A shares in the amount of $1,000,000 or more and/or  purchases  made by certain  qualifying  retirement or
     other plans are not subject to a sales charge, but may be subject to a contingent deferred sales charge. See "Class A Shares"
     and "Contingent Deferred Sales Charge and Waiver of Sales Charges" for an explanation of the charge.
<F5> There is no exchange fee for individual investors making exchanges over the Keystone Automated Response Line ("KARL"). (For a
     description of KARL, see "Shareholder Services.")
<F6> Expense ratios are estimated for the fiscal year ending March 31, 1996 after giving effect to the  reimbursement  by Keystone
     of expenses in accordance with certain voluntary expense limitations. Currently, Keystone has voluntarily limited expenses of
     Class A Shares to 0.75% of average daily net assets until  December 31, 1995.  Similarly,  Keystone has  voluntarily  limited
     expenses  of Class B and C shares to 1.50% of average  daily net assets of each such  class  until  December  31,  1995.  The
     estimated ratios above assume  Keystone's  extension of these expense limits until March 31, 1996, which Keystone is under no
     obligation to do. Absent voluntary expense limitations,  expense ratios for the fiscal year ending March 31, 1996 for the New
     York Insured Fund's Class A, B and C shares, respectively, are projected to be 1.59%, 2.35%, and 2.32%.
<F7> Long term  shareholders may pay more than the economic  equivalent of the maximum front end sales charges  permitted by rules
     adopted by the National Association of Securities Dealers, Inc.
<F8> The Securities and Exchange Commission requires use of a 5% annual return figure for purposes of this example.  Actual return
     for the Funds may be greater or less than 5%.

    Class A ............................................................      $55            $70           $ 87        $136
    Class B ............................................................      $15            $47           $ 82         N/A
    Class C ............................................................      $15            $47           $ 82        $179

<F1> Class B shares purchased on or after June 1, 1995 convert tax free to Class A shares after eight calendar years. See "Class B
     Shares" for more information.
<F2> Class C shares are  available  only  through  dealers who have entered into special  distribution  agreements  with  Keystone
     Investment Distributors Company, the Fund's principal underwriter.
<F3> The sales charge applied to purchases of Class A shares declines as the amount invested  increases.  See  "Alternative  Sales
     Options."
<F4> Purchases of Class A shares in the amount of $1,000,000 or more and/or  purchases  made by certain  qualifying  retirement or
     other plans are not subject to a sales charge, but may be subject to a contingent deferred sales charge. See "Class A Shares"
     and "Contingent Deferred Sales Charge and Waiver of Sales Charges" for an explanation of the charge.
<F5> There is no exchange fee for individual investors making exchanges over the Keystone Automated Response Line ("KARL"). (For a
     description of KARL, see "Shareholder Services.")
<F6> Expense ratios are for the fiscal year ended March 31, 1995 after giving effect to the  reimbursement by Keystone of expenses
     in accordance with certain voluntary expense  limitations.  Currently,  Keystone has voluntarily  limited expenses of Class A
     Shares to 0.75% of average daily net assets until December 31, 1995. Similarly,  Keystone has voluntarily limited expenses of
     Class B and C shares to 1.50% of average  daily net assets of each such class until  December 31, 1995.  Keystone is under no
     obligation to maintain these limits. Absent the voluntary expense limitations, expense ratios for the fiscal year ended March
     31, 1995 for the Texas Fund's Class A, B and C shares, respectively, would have been 2.57%, 3.36%, and 3.28%.
<F7> Long term  shareholders may pay more than the economic  equivalent of the maximum front end sales charges  permitted by rules
     adopted by the National Association of Securities Dealers, Inc. ("NASD").
<F8> The Securities and Exchange Commission requires use of a 5% annual return figure for purposes of this example.  Actual return
     for the Funds may be greater or less than 5%.

THE FUND AND ITS FUNDS

  The FUND is a non-diversified  open-end management investment company commonly
known as a mutual fund. The FUND was formed as a Massachusetts business trust on
September  13,  1990.  The FUND is one of thirty  funds  managed  or  advised by
Keystone Investment Management Company (formerly named Keystone Custodian Funds,
Inc.) ("Keystone"),  the FUND's investment adviser.  The FUND currently consists
of  five  separate  series  evidencing  interests  in  different  portfolios  of
securities.  The Florida  Fund and the  Pennsylvania  Fund were  established  on
September 19, 1990.  The  Massachusetts  Fund, the New York Insured Fund and the
Texas Fund were  established on February 21, 1992.  Shares of the  Massachusetts
Fund and the New York Insured  Fund were not offered  prior to February 4, 1994.
The FUND may offer additional Funds in the future.

INVESTMENT OBJECTIVES AND POLICIES

INVESTMENT OBJECTIVES

  Each of the Funds  seeks the  highest  possible  current  income  exempt  from
federal income taxes, while preserving capital.

FUNDS' PRINCIPAL INVESTMENTS

  Generally,  under ordinary circumstances,  each Fund invests substantially all
and at least 80% of its assets in federally  tax-exempt  obligations,  including
municipal bonds and notes and municipal tax-exempt  commercial paper obligations
that  are  obligations  issued  by or  on  behalf  of  states,  territories  and
possessions  of the United States  ("U.S."),  the District of Columbia and their
political subdivisions, agencies and instrumentalities,  the interest from which
is exempt from federal income taxes, including the alternative minimum tax. Thus
it is possible that up to 20% of a Fund's assets could be in securities  subject
to the alternative minimum tax and/or in taxable obligations.

  Municipal  bonds include fixed,  variable or floating rate general  obligation
and revenue bonds  (including  municipal lease  obligations,  resource  recovery
bonds and zero coupon bonds).  Municipal notes include tax  anticipation  notes,
bond anticipation notes, revenue anticipation notes and project notes. Municipal
commercial   paper   obligations  are  unsecured   promissory  notes  issued  by
municipalities to meet short term credit needs.

  The FLORIDA FUND seeks, in addition,  to hold  securities  exempt from Florida
intangible taxes.

  The PENNSYLVANIA FUND seeks, in addition,  the highest possible current income
exempt from  Pennsylvania  state and local taxes while preserving  capital.  The
Pennsylvania  Fund  also  seeks  to hold  securities  exempt  from  Pennsylvania
personal property taxes.

  The TEXAS FUND provides,  in addition,  an opportunity for investors to invest
in  municipal  securities  of the State of Texas,  its  political  subdivisions,
agencies and instrumentalities.  Texas currently imposes no personal income tax.
In the event Texas enacts a personal  income tax,  the Texas Fund will seek,  in
addition,  the highest possible current income exempt from Texas personal income
taxes while preserving capital.

FLORIDA FUND

  Under ordinary  circumstances,  the Florida Fund invests substantially all and
at least 80% of its assets in municipal  obligations  exempt from federal  taxes
and the Florida intangibles tax.

  For a further  discussion of Florida tax  treatment and the factors  affecting
investment in Florida municipal obligations, see Exhibit A.

MASSACHUSETTS FUND

  Under ordinary  circumstances,  the Massachusetts Fund invests at least 80% of
its assets in  securities  the interest  from which is exempt from federal taxes
and  Massachusetts  state income taxes. The  Massachusetts  Fund invests in debt
obligations of The Commonwealth of Massachusetts and its political subdivisions,
agencies,  authorities  and  instrumentalities  and  debt  obligations  of other
qualifying issuers, such as U.S. territories.

  The Massachusetts  Fund invests at least 80% of its assets in investment grade
municipal  obligations -- bonds rated at the date of investment  within the four
highest grades by Standard & Poor's Corporation ("S&P") (AAA, AA, A and BBB), by
Moody's  Investors  Service,  Inc.  ("Moody's")  (Aaa,  Aa, A and Baa), by Fitch
Investors Service, Inc. - Municipal Division ("Fitch") (AAA, AA, A and BBB), or,
if not rated or rated under a different  system,  are of  comparable  quality to
obligations  so rated as  determined  by  Keystone.  Securities  that are in the
lowest investment grade (BBB or Baa) may have speculative  characteristics.  The
Fund may seek to maximize  return with  respect to a portion (not to exceed 20%)
of its assets.  Such maximum  return is ordinarily  associated  with high yield,
high risk  municipal  bonds in the lower  rating  categories  of the  recognized
rating  agencies or that are unrated (high yield bonds).  Such high yield,  high
risk bonds generally  involve greater  volatility of price and risk of principal
and income  than bonds in the higher  rating  categories  and are,  on  balance,
considered predominantly  speculative.  High yield bonds are also commonly known
as "junk bonds."

  For a further  discussion  of  Massachusetts  tax  treatment  and the  factors
affecting investment in Massachusetts municipal obligations, see Exhibit A.


NEW YORK INSURED FUND

  Under ordinary  circumstances,  the New York Insured Fund invests at least 80%
of its assets in securities the interest from which is exempt from federal taxes
and New York state  income  taxes.  The New York  Insured  Fund  invests in debt
obligations of the State of New York and its political  subdivisions,  agencies,
authorities  and  instrumentalities  and debt  obligations  of other  qualifying
issuers, such as U.S. territories.

  As more fully  discussed below in the section  entitled  "Insurance," at least
80% of the  municipal  securities  in the  investment  portfolio of the New York
Insured  Fund  will be  insured  as to  timely  payment  of both  principal  and
interest.  The purpose of insuring these investments is to minimize credit risks
associated  with  defaults  in  municipal  securities  owned by the  Fund.  Such
insurance,  however,  does not insure against market risk and therefore will not
guarantee the market value of the securities in the Fund's  portfolio upon which
the net asset value of the Fund's shares is based.

  For a further  discussion of New York tax treatment and the factors  affecting
investment in New York municipal obligations, see Exhibit A.


PENNSYLVANIA FUND

  Under ordinary circumstances,  the Pennsylvania Fund invests substantially all
and at least 80% of its assets in  municipal  obligations  exempt  from  federal
taxes  and  Pennsylvania   state  income  taxes.  The  securities  include  debt
obligations of the Commonwealth of Pennsylvania and its political  subdivisions,
agencies,  authorities  and  instrumentalities  and  debt  obligations  of other
qualifying issuers, such as Puerto Rico and the Virgin Islands. In addition, the
Pennsylvania  Fund  attempts  to invest in  municipal  obligations  exempt  from
Pennsylvania  local  income  taxes and seeks to hold,  on the annual  assessment
date, municipal obligations exempt from Pennsylvania personal property taxes.

  Many of the municipal  obligations in which the  Pennsylvania  Fund intends to
invest generate income that is exempt from Pennsylvania state income taxes.

  For a  further  discussion  of  Pennsylvania  tax  treatment  and the  factors
affecting investment in Pennsylvania municipal obligations, see Exhibit A.


TEXAS FUND

  Under ordinary circumstances,  the Texas Fund invests substantially all and at
least 80% of its assets in municipal  obligations of the State of Texas that are
exempt from federal income taxes. The securities include debt obligations of the
State  of  Texas  and its  political  subdivisions,  agencies,  authorities  and
instrumentalities. Texas does not currently impose an income tax on individuals.

  For a further  discussion  of Texas tax  treatment  and the factors  affecting
investment in Texas municipal obligations, see Exhibit A.

MUNICIPAL OBLIGATIONS

  Municipal  obligations  include debt  obligations  issued by or on behalf of a
political  subdivision of the U.S. or any agency or  instrumentality  thereof to
obtain funds for various public  purposes.  In addition,  municipal  obligations
include certain types of industrial  development  bonds that have been or may be
issued by or on  behalf of public  authorities  to  finance  privately  operated
facilities.  General obligation bonds involve the credit of an issuer possessing
taxing power and are payable from the issuer's  general  unrestricted  revenues.
Their payment may be dependent upon an appropriation by the issuer's legislative
body and may be subject  to  quantitative  limitations  on the  issuer's  taxing
power. Limited obligation or revenue bonds are payable only from the revenues of
a  particular  facility  or class of  facilities  or,  in some  cases,  from the
proceeds of a special excise or other specific revenue source,  such as the user
of the facility.  Since each Fund considers  preservation  of capital as well as
the level of tax-exempt income,  each Fund may realize less income than a mutual
fund willing to expose shareholders' capital to greater risk.

  The Tax Reform Act of 1986 made significant  changes in the federal tax status
of certain  obligations  that were previously fully federally  tax-exempt.  As a
result,  three  categories of such  obligations  issued after August 7, 1986 now
exist:  (1) "public  purpose" bonds,  the income from which remains fully exempt
from federal income tax; (2) qualified "private activity" industrial development
bonds, the income from which, while exempt from federal income tax under Section
103 of the Internal Revenue Code (the "Code"),  is includable in the calculation
of the federal  alternative  minimum tax; and (3)  "private  activity"  (private
purpose)  bonds,  the income from which is not exempt from federal income tax. A
Fund will not invest in private  purpose  bonds and,  except as described  under
"Other Eligible  Investments,"  will not invest in qualified  "private activity"
industrial  development bonds whose distributions are subject to the alternative
minimum tax.

  Each Fund,  except the  Massachusetts  Fund,  invests  entirely  in  municipal
obligations  only if at the date of  investment  they are rated  within the four
highest  grades by S&P (AAA, AA, A and BBB), by Moody's (Aaa, Aa, A and Baa), by
Fitch (AAA,  AA, A and BBB) or, if not rated or rated under a different  system,
are of comparable quality to obligations so rated as determined by Keystone.

  While a Fund  may  invest  in  securities  of any  maturity,  it is  currently
expected that a Fund will not invest in securities  with maturities of more than
30 years or less than 5 years (other than certain money market securities).

OTHER ELIGIBLE INVESTMENTS

  A Fund may invest up to 20% of its assets under ordinary  circumstances and up
to 100% of its assets for temporary defensive purposes in the following types of
instruments:  (1) commercial  paper,  including master demand notes, that at the
date of  investment  is rated  A-1  (the  highest  grade by S&P),  PRIME- 1 (the
highest  grade by  Moody's)  or, if not rated by such  services,  is issued by a
company  that at the date of  investment  has an  outstanding  issue  rated A or
better by S&P or Moody's; (2) obligations, including certificates of deposit and
bankers'  acceptances,  of banks or savings and loan  associations  that have at
least $1  billion  in assets  as of the date of their  most  recently  published
financial   statements  and  are  members  of  the  Federal  Deposit   Insurance
Corporation,  including U.S.  branches of foreign banks and foreign  branches of
U.S. banks;  (3) corporate  obligations  (maturing in 13 months or less) that at
the date of investment are rated A or better by S&P or Moody's;  (4) obligations
issued or guaranteed by the U.S.  government or by any agency or instrumentality
of the U.S.; (5) qualified "private activity" industrial  development bonds, the
income from which, while exempt from federal income tax under Section 103 of the
Code, is includable in the calculation of the federal  alternative  minimum tax;
and (6)  municipal  obligations,  the income from which is exempt  from  federal
income tax, but not exempt from income tax, personal property tax or intangibles
tax in a state  for  which a Fund is named  and  where  such  taxes  apply.  For
example,  each Fund may assume a temporary  defensive  position upon  Keystone's
determination  that  market  conditions  so  warrant.  If a  Fund  is  investing
defensively, it is not pursuing its investment objectives.

  Each  Fund may  enter  into  repurchase  and  reverse  repurchase  agreements,
purchase and sell securities on a when issued and delayed delivery basis,  write
covered  call and put  options  and  purchase  call and put  options,  including
purchasing call and put options to close out existing positions,  and may employ
new  investment  techniques  with  respect to such  options.  Each Fund may also
engage in financial  futures  contracts  and related  options  transactions  for
hedging  purposes  and  not  for  speculation  and  may  employ  new  investment
techniques  with  respect to such  futures  contracts  and related  options.  In
addition,  each Fund may invest in municipal obligations  denominated in foreign
currencies and may use  subsequently  developed  investment  techniques that are
related to any of its  investment  policies.  None of the Funds are  expected to
enter into repurchase agreements in the ordinary course of business.

  In addition to the options and futures mentioned above, if consistent with its
investment  objectives,  the Fund may also  invest  in  certain  other  types of
"derivative investments," including structured securities.

  For  further  information  about  the  types  of  investments  and  investment
techniques  available  to  the  Funds,   including  the  associated  risks,  see
"Additional  Investment  Information" located at the back of this prospectus and
the statement of additional information.

  There can be no assurance that a Fund will achieve its  investment  objectives
since there is uncertainty in every investment.

INSURANCE

  At least 80% of the  municipal  securities  in the  portfolio  of the New York
Insured Fund will consist of obligations  that at all times are fully insured as
to the payment of all principal  and interest  when due ("Insured  Securities").
Each Insured  Security in the  portfolio  will be covered by either a "New Issue
Insurance Policy," "Portfolio  Insurance Policy" issued by a qualified municipal
bond insurer,  or a "Secondary  Insurance Policy." The insurance does not insure
against  market risk and  therefore  does not  guarantee the market value of the
securities in the New York Insured Fund's portfolio.  Similarly, because the net
asset value of the New York Insured Fund's shares is based upon the market value
of the securities in the  portfolio,  such insurance does not cover or guarantee
the value of the New York Insured Fund's shares.

NEW ISSUE INSURANCE POLICIES

  New Issue  Insurance  Policies are obtained by the  respective  issuers of the
municipal securities, and all premiums respecting such securities have been paid
in advance by such issuers.  Such policies are  noncancellable and will continue
in force so long as the municipal securities are outstanding, and the respective
insurers remain in business. Since New Issue Insurance Policies remain in effect
as long as the securities are  outstanding,  the insurance may have an effect on
the resale  value of the  Insured  Securities.  Therefore,  New Issue  Insurance
Policies may be  considered  to represent an element of market value with regard
to the Insured  Securities,  but the exact effect,  if any, of this insurance on
such market value cannot be  estimated.  The New York Insured Fund will purchase
municipal  securities subject to New Issue Insurance Policies only if the claims
paying ability of the insurer thereof is rated AAA by S&P or Aaa by Moody's.

PORTFOLIO INSURANCE POLICIES

  Portfolio  Insurance Policies are obtained by the New York Insured Fund from a
qualified  municipal  bond insurer and are effective only so long as the Fund is
in existence, the insurer is still in business and meeting its obligations,  and
the Insured Securities  described in the policy are held by the New York Insured
Fund. Premium rates for each issue of securities covered by the policy are fixed
for the  life of the New York  Insured  Fund and are  periodically  adjusted  to
reflect purchases and sales of covered securities.  The premium on the Portfolio
Insurance  Policy is an item of expense  and will be  reflected  in the New York
Insured  Fund's  average  annual  expenses.  Premiums are paid from the New York
Insured  Fund's  assets and reduce the  current  yield on its  portfolio  by the
amount thereof. The insurer cannot cancel coverage already in force with respect
to Insured  Securities  owned by the New York  Insured  Fund and  covered by the
policy, except for nonpayment of premiums.

SECONDARY INSURANCE POLICIES

  The New York Insured Fund may, at any time,  purchase  Secondary  Insurance on
any  municipal  security  held by the  Fund.  Such  insurance  coverage  will be
noncancellable  and will continue in force so long as the  securities so insured
are  outstanding.  Secondary  Insurance will likely be purchased by the New York
Insured Fund if, in the opinion of Keystone, the market value or net proceeds of
the sale of a  security  by the Fund  would  exceed  the  current  value of such
security (without insurance) plus the cost of such insurance.  When the New York
Insured Fund purchases Secondary  Insurance,  the single premium is added to the
cost basis of the security and is not considered an item of expense of the Fund.
One of the  purposes of such  insurance is to enable the  securities  covered by
such insurance to be sold as "AAA" or "Aaa" rated Insured Securities at a market
price higher than that which might  otherwise be  obtainable  if the  securities
were sold without the  insurance  coverage.  Therefore,  such  insurance  may be
considered  to represent an element of market value of such Insured  Securities,
although the exact effect, if any, on such market value cannot be estimated. Any
difference between the excess of such a security's market value as an AAA or Aaa
rated  security over its market value without such rating,  including the single
premium cost  thereof,  would inure to the New York Insured Fund in  determining
the net capital gain or loss  realized by the Fund upon the sale of such Insured
Security.

FUNDAMENTAL NATURE OF INVESTMENT OBJECTIVES

  The  investment  objectives  of each Fund and the  requirement  that each Fund
invest,  under ordinary  circumstances,  at least 80% of its assets in federally
tax-exempt municipal  obligations that are also exempt from certain taxes in the
state for which it is named, as set forth above,  are fundamental and may not be
changed without the vote of a majority of the affected Fund's outstanding shares
(as defined in the Investment Company Act of 1940 (the "1940 Act")).

INVESTMENT RESTRICTIONS

  Each Fund has adopted the following fundamental restrictions summarized below,
which may not be changed  without the vote of a 1940 Act majority of such Fund's
outstanding  shares.  These  restrictions  and  certain  other  fundamental  and
nonfundamental  restrictions  are  contained  in  the  statement  of  additional
information.  Unless otherwise stated,  all references to a Fund's assets are in
terms of current market value.

  Generally, each Fund may not do the following:

  (1)  purchase  any  security  of any  issuer  (other  than  issues of the U.S.
government,  its agencies or  instrumentalities) if as a result more than 25% of
its total assets would be invested in a single  industry,  including  industrial
development  bonds  from the  same  facility  or  similar  types of  facilities;
governmental  issuers  of  municipal  bonds are not  regarded  as  members of an
industry,  and the Fund may  invest  more than 25% of its  assets in  industrial
development bonds;

  (2) invest more than 10% of its assets in securities with legal or contractual
restrictions  on resale or in  securities  for which market  quotations  are not
readily available, or in repurchase agreements maturing in more than seven days;

  (3) borrow money or enter into reverse repurchase agreements, except that each
Fund may enter into reverse repurchase agreements or borrow money from banks for
temporary  or  emergency  purposes in  aggregate  amounts up to one-third of the
value of the Fund's net assets;  provided that while  borrowings from banks (not
including reverse repurchase agreements) exceed 5% of the Fund's net assets, any
such borrowings will be repaid before additional investments are made; and

  (4) make  loans,  except that each Fund may  purchase or hold debt  securities
consistent with its investment  objectives,  lend portfolio securities valued at
not more  than  15% of its  total  assets  to  broker-dealers,  and  enter  into
repurchase agreements.

  The  Funds  are   non-diversified   under  the  federal  securities  laws.  As
non-diversified  funds,  there  is no  restriction  under  the  1940  Act on the
percentage  of assets that may be invested at any time in the  securities of any
one issuer. The Funds intend to comply, however, with the Code's diversification
requirements  and  other  requirements   applicable  to  "regulated   investment
companies"  to ensure  they will not be  subject to U.S.  federal  income tax on
income and capital gain distributions to shareholders.

  For this reason,  each Fund has adopted the investment  restriction  set forth
below,  which may not be changed  without  the  approval  of a  majority  of its
outstanding  shares.  Specifically,  a Fund may not  purchase a security if more
than 25% of the Fund's  total assets  would be invested in the  securities  of a
single   issuer   (other   than   the  U.S.   government,   its   agencies   and
instrumentalities)  or, with respect to 50% of the Fund's total assets,  if more
than 5% of such assets would be invested in the  securities  of a single  issuer
(other than the U.S. government, its agencies and instrumentalities).

  As a matter of  practice,  a Fund  treats  reverse  repurchase  agreements  as
borrowings  for purposes of  compliance  with the  limitations  of the 1940 Act.
Reverse  repurchase  agreements will be taken into account along with borrowings
from  banks for  purposes  of the 5% limit  set  forth in the  third  investment
restriction above.

  The  foregoing  is only a summary of the Funds'  investment  restrictions  and
policies.  See the statement of additional  information for details and the full
text of the Funds' investment restrictions and related policies.

RISK FACTORS

GENERAL
  Investing in a Fund  involves  the risk common to  investing in any  security,
i.e.,  the net asset  value of a share of the Fund can  increase  or decrease in
response  to changes in economic  conditions,  interest  rates and the  market's
perception of the underlying portfolio securities of the Fund.

  By itself, a Fund does not constitute a balanced investment program and is not
designed for investors seeking capital appreciation or maximum tax-exempt income
irrespective  of fluctuations  in principal or  marketability.  Shares of a Fund
would not be suitable for  tax-exempt  institutions  and may not be suitable for
certain  retirement  plans that are unable to benefit from the Fund's  federally
tax-exempt dividends.  In addition, the Funds may not be appropriate investments
for entities that are "substantial  users" of facilities  financed by industrial
development bonds or related persons thereof.

  To the  extent  the  Funds  are  not  fully  diversified,  they  may  be  more
susceptible to adverse economic,  political or regulatory developments affecting
a  single  issuer  than  would  be the  case  if the  Funds  were  more  broadly
diversified.

  In addition,  the market value of the fixed income  securities in which a Fund
may invest may vary inversely to changes in prevailing interest rates.

MUNICIPAL OBLIGATIONS

  A Fund's  ability to achieve its  objectives  depends  partially on the prompt
payment by issuers of the interest on and principal of the municipal obligations
held by the Fund.  A  moratorium,  default or other  nonpayment  of  interest or
principal  when due on any  municipal  obligation,  in addition to affecting the
market value and liquidity of that particular security,  could affect the market
value and liquidity of other municipal  obligations held by a Fund. In addition,
the  market  for  municipal  obligations  is often  thin and can be  temporarily
affected by large purchases and sales, including those by a Fund.

  From time to time, proposals have been introduced before the U.S. Congress for
the purpose of restricting  or eliminating  the federal income tax exemption for
interest on municipal obligations,  and similar proposals may well be introduced
in the future.  If such a proposal were enacted,  the  availability of municipal
obligations  for investment by each Fund and the value of the Fund's  securities
could be materially  affected.  In such an event,  the FUND would reevaluate its
Funds' investment  objectives and policies and consider changes in the structure
of the Funds or dissolution.

  If and when a Fund invests in municipal  lease  obligations,  the  possibility
exists that a municipality may not appropriate the funds for lease payments. The
FUND's Board of Trustees  will be  responsible  for  determining,  on an ongoing
basis,  the credit  quality  of such  leases,  including  an  assessment  of the
likelihood of cancellation of any such lease.

NONINVESTMENT GRADE BONDS

  The Massachusetts Fund's investment policy allows the Fund to invest a portion
(not to exceed 20%) of its assets in high yield,  high risk municipal bonds. The
degree to which the Fund will hold such  securities  will,  among other  things,
depend upon Keystone's  economic forecast and its judgment as to the comparative
values  offered by high yield,  high risk bonds and higher  quality  bonds.  The
Massachusetts  Fund seeks to invest up to 20% of its assets  aggressively and to
maximize  return over time from a combination  of many factors,  including  high
current  income and  capital  appreciation  from high  yield,  high risk  bonds.
Although the total amount invested in high yield,  high risk securities will not
exceed  20%  of the  assets  of the  Massachusetts  Fund,  the  Fund  may  (as a
non-diversified  fund) invest as much as the entire 20% in the  securities  of a
single issuer. To that extent, the Massachusetts Fund may be more susceptible to
adverse economic, political or regulatory developments affecting a single issuer
than would be the case if the Fund were more broadly diversified.

  Such  aggressive  investing  involves risks that are greater than the risks of
investing  in higher  quality  debt  securities.  These risks are  discussed  in
greater detail below and include risks from (1) interest rate  fluctuation;  (2)
changes in credit status,  including  weaker overall credit condition of issuers
and risks of default; (3) industry,  market and economic risk; (4) volatility of
price  resulting  from  broad  and  rapid  changes  in the  value of  underlying
securities;  and (5) greater  price  variability  and credit  risks of such high
yield,  high  risk  securities  as zero  coupon  bonds and  pay-in-kind  ("PIK")
securities.

  Specifically, investors should be aware of the following:

  (1)  securities  rated  BB or  lower  by S&P or BA or  lower  by  Moody's  are
considered  predominantly  speculative with respect to the ability of the issuer
to meet principal and interest payments;

  (2) the value of high yield,  high risk securities may be more  susceptible to
real or perceived adverse economic,  company or industry  conditions than is the
case for higher quality securities;

  (3) adverse market,  credit or economic  conditions could make it difficult at
certain times to sell certain high yield, high risk securities held by the Fund;

  (4) the  secondary  market for high yield,  high risk  securities  may be less
liquid than the secondary market for higher quality securities, which may affect
the  value of  certain  high  yield,  high risk  securities  held by the Fund at
certain times; and

  (5) high  yield,  high risk zero coupon  securities  may be subject to greater
changes  in value due to  market  conditions,  the  absence  of a cash  interest
payment and the tendency of issuers of such  securities  to have weaker  overall
credit conditions than other high yield, high risk securities.

  These  characteristics of high yield, high risk securities make them generally
more appropriate for long term investment.

  If and when a Fund invests in zero coupon  bonds,  the Fund does not expect to
have enough zero coupon bonds to have a material  effect on dividends.  The FUND
has  undertaken  to a state  securities  authority to disclose  that zero coupon
securities  pay no interest to holders prior to maturity,  and that the interest
on these  securities  is  reported  as income to a Fund and  distributed  to its
shareholders.  These  distributions must be made from the Fund's cash assets or,
if necessary, from the proceeds of sales of portfolio securities.  The Fund will
not be able to purchase additional income producing securities with cash used to
make such  distributions,  and its current income ultimately may be reduced as a
result.

  These  risks  provide the  opportunity  for  maximizing  return over time on a
portion of the Massachusetts Fund's assets, but may result in greater upward and
downward  movement  of the net asset  value per share of the Fund.  As a result,
they should be carefully considered by investors.

  The maximum return sought by the Massachusetts  Fund with respect to up to 20%
of its assets is  ordinarily  associated  with  securities  in the lower  rating
categories  of the  recognized  rating  agencies  or with  securities  that  are
unrated.  Such high yield,  high risk securities are generally rated BB or lower
by S&P or Ba or lower by  Moody's.  The Fund may invest in  securities  that are
rated  as  low as D by  S&P  and C- by  Moody's.  These  rating  categories  are
described  in the section of this  prospectus  entitled  "Additional  Investment
Information." The Fund intends to invest in D rated debt only in cases where, in
Keystone's judgment, there is a distinct prospect of improvement in the issuer's
financial position as a result of the completion of reorganization or otherwise.
The Fund may also invest in unrated  securities  that, in  Keystone's  judgment,
offer comparable  yields and risks to those of securities that are rated as well
as non-investment quality zero coupon and PIK securities.

  Since the Fund takes an  aggressive  approach  to  investing  a portion of its
assets, Keystone tries to maximize the return by controlling the risk associated
with those  investments  through  diversification,  credit  analyses,  review of
sector and industry  trends,  interest  rate  forecasts  and economic  analysis.
Keystone's  analysis of  securities  focuses on values  based on factors such as
asset values,  earnings  prospects and the quality of management of the company.
In making  investment  recommendations,  Keystone also considers current income,
potential for capital  appreciation,  maturity  structure,  quality  guidelines,
coupon  structure,  average yield,  percentage of zeros and PIKs,  percentage of
non-accruing items and yield to maturity.

  Keystone  also  considers  the ratings of Moody's and S&P  assigned to various
securities,  but does not rely  solely on ratings  assigned  by Moody's  and S&P
because (1) Moody's and S&P  assigned  ratings are based  largely on  historical
financial data and may not accurately  reflect the current  financial outlook of
municipalities;  and (2)  there  can be  large  differences  among  the  current
financial conditions of issuers within the same rating category.

TAX CONSIDERATIONS

  For a discussion of the tax considerations for each state and special factors,
including the risks  associated with investing in the municipal  securities of a
single state,  see Exhibit A to this  prospectus and Appendix A to the statement
of additional information.

PRICING SHARES

  The net asset value of a Fund share is computed each day on which the New York
Stock  Exchange  (the  "Exchange")  is open as of the  close of  trading  on the
Exchange  (currently  4:00 p.m.  eastern  time for the  purpose of pricing  Fund
shares)  except  on  days  when  changes  in the  value  of a  Fund's  portfolio
securities do not affect the current net asset value of its shares. The Exchange
currently is closed on weekends,  New Year's Day,  Presidents' Day, Good Friday,
Memorial Day,  Independence Day, Labor Day,  Thanksgiving Day and Christmas Day.
The net asset  value per share of each Fund is  arrived  at by  determining  the
value of the Fund's assets,  subtracting its liabilities and dividing the result
by the number of its shares outstanding. Net asset value per share is calculated
to two decimal  places for purposes of  purchases  and  redemptions  of a Fund's
shares.

  The Funds value municipal obligations on the basis of valuations provided by a
pricing  service,   approved  by  the  FUND's  Board  of  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. Each Fund values its short-term  instruments as
follows: short-term instruments with maturities of sixty days or less are valued
at  amortized  cost  (original  purchase  cost as adjusted for  amortization  of
premium or accretion of discount),  which,  when combined with accrued interest,
approximates market; short-term instruments having maturities of more than sixty
days for which market  quotations  are readily  available  are valued at current
market value; and short-term  instruments  maturing in more than sixty days when
purchased  that are held on the  sixtieth  day prior to  maturity  are valued at
amortized  cost (market value on the sixtieth day adjusted for  amortization  of
premium or accretion of discount),  which,  when combined with accrued interest,
approximates  market;  and  which,  in  either  case,  reflects  fair  value  as
determined by the Board of Trustees.  All other investments are valued at market
value or, where market  quotations are not readily  available,  at fair value as
determined  in good faith  according to procedures  established  by the Board of
Trustees.

DIVIDENDS AND TAXES

  Each Fund intends to declare  dividends from net  investment  income daily and
distribute  to its  shareholders  such  dividends  monthly  and to  declare  and
distribute  all net realized  long-term  capital  gains  annually.  Shareholders
receive Fund  distributions  in the form of  additional  shares of that class of
shares upon which the distribution is based or, at the shareholder's  option, in
cash.  Shareholders  of a Fund who have not opted to  receive  cash prior to the
payable date for any dividend from net investment  income or the record date for
any capital gains distribution will have the number of such shares determined on
the basis of the Fund's net asset  value per share  computed  at the end of that
day after adjustment for the distribution.  Net asset value is used in computing
the  number  of  shares  in  both   capital   gains  and   income   distribution
reinvestments.  There is a possibility that shareholders may lose the tax-exempt
status on accrued income on municipal  bonds if shares of the Funds are redeemed
before a dividend has been declared.

  As of April 1, 1995, in compliance with a recent ruling issued by the Internal
Revenue  Service  ("IRS"),  the FUND  treats its 12b-1 fees for tax  purposes as
operating expenses rather than capital charges.

  Account  statements  and/or checks as appropriate  will be mailed within seven
days after the Fund pays the distribution. Unless the FUND receives instructions
to the contrary  before the record or payable  date, as the case may be, it will
assume that a shareholder wishes to receive that distribution and future capital
gains and income distributions in shares.  Instructions continue in effect until
changed in writing.

  Each of the Funds  intends to qualify in the future as a regulated  investment
company under the Code.  Each Fund is a separate  taxable entity for purposes of
Code provisions applicable to regulated investment companies.  Each of the Funds
qualifies if, among other things,  it distributes to its  shareholders  at least
90% of its net investment  income for its fiscal year. Each Fund also intends to
make  timely  distributions,  if  necessary,  sufficient  in amount to avoid the
nondeductible  4% excise tax  imposed on a regulated  investment  company to the
extent that it fails to distribute, with respect to each calendar year, at least
98% of its  ordinary  income for such  calendar  year and 98% of its net capital
gains for the one-year  period ending on October 31 of such calendar  year.  Any
taxable  distribution (1) would be declared in October,  November or December to
shareholders  of  record  in such a month,  (2)  would be paid by the  following
January 31, and (3) would be  includable in the taxable  income of  shareholders
for the year in which such distribution was declared. If a Fund qualifies and if
it distributes  substantially  all of its net investment  income and net capital
gains,  if any, to  shareholders,  it will be relieved of any federal income tax
liability.

  Each Fund  expects that  substantially  all of its  dividends  will be "exempt
interest  dividends,"  which should be treated as excludable  from federal gross
income. In order to pay exempt interest dividends,  at least 50% of the value of
the Fund's assets must consist of federally tax-exempt  obligations at the close
of each  quarter.  An exempt  interest  dividend is any dividend or part thereof
(other than a capital  gain  dividend)  paid by the Fund with respect to its net
federally  excludable  municipal obligation interest and designated as an exempt
interest  dividend in a written notice mailed to each shareholder not later than
60 days  after  the  close of its  taxable  year.  The  percentage  of the total
dividends  paid by a Fund with  respect to any taxable  year that  qualifies  as
exempt  interest  dividends  will be the same for all  shareholders  of the Fund
receiving  dividends  with respect to such year.  If a  shareholder  receives an
exempt interest  dividend with respect to any share and such share has been held
for six months or less,  any loss on the sale or  exchange of such share will be
disallowed to the extent of the exempt interest dividend amount.

  Any  shareholder  of a Fund  who may be a  "substantial  user"  of a  facility
financed with an issue of tax-exempt obligations or a "related person" to such a
user should  consult his tax adviser  concerning  his  qualification  to receive
exempt  interest  dividends  should  the Fund hold  obligations  financing  such
facility.

  Interest on certain  "private  activity  bonds"  issued  after August 7, 1986,
although  otherwise  tax  exempt,  is  treated  as a  tax  preference  item  for
alternative minimum tax purposes. Under regulations to be promulgated,  a Fund's
exempt  interest   dividends  will  be  treated  the  same  way  to  the  extent
attributable  to  interest  paid  on  such  private  activity  bonds.  Corporate
shareholders  should also be aware that the receipt of exempt interest dividends
could subject them to  alternative  minimum tax under the  provisions of Section
56(g) of the Code (relating to "adjusted current earnings").

  Since  none of a  Fund's  income  will  consist  of  corporate  dividends,  no
distributions will qualify for the corporate dividends received deduction.

  Each  Fund  intends  to  distribute  its net  capital  gains as  capital  gain
dividends;  shareholders should treat such dividends as long-term capital gains.
Such  distributions  will be designated  as capital gain  dividends by a written
notice mailed to each  shareholder  no later than 60 days after the close of the
Fund's taxable year. If a shareholder receives a capital gain dividend and holds
his shares for six months or less,  then any allowable  loss on  disposition  of
such shares will be treated as a  long-term  capital  loss to the extent of such
capital gain dividend.

  Interest on indebtedness  incurred or continued by shareholders to purchase or
carry shares of a Fund will not be deductible for federal income tax purposes to
the extent of the portion of the interest  expense  relating to exempt  interest
dividends;  that  portion  is  determined  by  multiplying  the total  amount of
interest  paid or accrued on the  indebtedness  by a fraction,  the numerator of
which is the exempt interest  dividends received by a shareholder in his taxable
year and the  denominator of which is the sum of the exempt  interest  dividends
and the taxable  distributions out of the Fund's investment income and long-term
capital gains received by the shareholder.

  The Funds may acquire options to "put" specified  securities to municipal bond
dealers or issuers from whom the securities  are purchased.  It is expected that
each Fund will be treated  for federal  income tax  purposes as the owner of the
municipal bonds acquired subject to the put. The interest on the municipal bonds
will be tax-exempt to the Funds,  and the purchase prices paid by the Funds must
be allocated  between such  securities and the puts based upon their  respective
fair market values. The IRS has not issued a published ruling on this matter and
could reach a different conclusion.

STATE INCOME TAXES

  The exemption of interest on municipal  bonds for federal  income tax purposes
does not necessarily result in exemption under the income, corporate or personal
property tax laws of any state or city.  Generally,  individual  shareholders of
the Funds  receive  tax-exempt  treatment  at the state level for  distributions
derived from  municipal  securities of their state of residency.  Texas does not
currently  impose  any  income  tax on  individuals  or  corporate  shareholders
(although  Texas does  impose a corpo- rate  franchise  tax based,  in part,  on
reportable  federal  taxable  income on those  corporations  doing  business  in
Texas). Florida does not currently impose any individual income tax, although it
does impose a tax on corporate income.  Each Fund will report to shareholders on
a state by state  basis the  sources of its  exempt  interest  dividends.  For a
further  discussion of state tax treatment  relating to each Fund, see Exhibit A
to this prospectus.

  As mentioned above, at the end of each quarter, at least 50% of the value of a
Fund's  assets  must  be  invested  in  municipal   obligations   in  order  for
distributions  to  qualify  as exempt  interest  dividends.  Under  particularly
unusual  circumstances,  such  as  when  a  Fund  is  in a  prolonged  defensive
investment position, it is possible that no portion of a Fund's distributions of
income to its shareholders for a fiscal year would be exempt from federal income
tax.  The  FUND  does not  presently  anticipate,  however,  that  such  unusual
circumstances will occur.

  The foregoing is only a summary of some of the  important  tax  considerations
generally  affecting the FUND, its Funds and their  shareholders.  No attempt is
made to present a detailed  explanation  of the federal or state income or other
tax treatment of the FUND, its Funds or their shareholders,  and this discussion
is  not  intended  as  a  substitute  for  careful  tax  planning.  Accordingly,
shareholders are urged to consult their tax advisers with specific  reference to
their tax situation.

FUND MANAGEMENT AND EXPENSES
BOARD OF TRUSTEES
Under Massachusetts law, the FUND's Board of Trustees has absolute and exclusive
control over the  management  and  disposition of all assets of the FUND and its
Funds.  Subject to the  authority of the Board of Trustees,  Keystone  serves as
investment  adviser to the FUND and its Funds and is responsible for the overall
management of the FUND's business and affairs.


INVESTMENT ADVISER

  Keystone,  the FUND's  investment  adviser,  located at 200  Berkeley  Street,
Boston,   Massachusetts   02116-5034,   has  provided  investment  advisory  and
management  services to investment  companies and private  accounts since it was
organized  in  1932.   Keystone  is  a   wholly-owned   subsidiary  of  Keystone
Investments,  Inc.  (formerly  Keystone Group,  Inc.) ("Keystone  Investments"),
located at 200 Berkeley Street, Boston, Massachusetts 02116-5034.

  Keystone  Investments  is a  corporation  predominantly  owned by current  and
former  members of  management  of Keystone  and its  affiliates.  The shares of
Keystone Investments common stock beneficially owned by management are held in a
number of voting trusts, the trustees of which are George S. Bissell,  Albert H.

  Pursuant to its  Investment  Advisory and  Management  Agreement with the FUND
(the "Advisory Agreement"), Keystone provides investment advisory and management
services to the FUND and each Fund.

  Each Fund pays  Keystone a fee for its  services  at the annual rate set forth
below:

                                                                     Aggregate

0.25% of amounts over                                       $500,000,000

computed as of the close of business  each  business day and paid daily.  During
the year ended March 31, 1995, the Florida, Pennsylvania and Texas Funds paid or
accrued to Keystone  investment  management and administrative  services fees of
$515,205 (0.52% of the Fund's average annual net assets), $357,852 (0.54% of the
Fund's  average  annual net assets),  and $25,402  (0.55% of the Fund's  average
annual net assets), respectively.  During the year ended March 31, 1995, the New
York  Insured and  Massachusetts  Funds paid or accrued to  Keystone  investment
management  and  administrative  services  fees of $63,808  (0.55% of the Fund's
average  annual net assets) and $43,636  (0.55% of the Fund's average annual net
assets), respectively.

  The Advisory  Agreement  continues in effect from year to year only so long as
such  continuance  is  specifically  approved at least  annually by the Board of
Trustees or by vote of a majority  of the  outstanding  shares of each Fund.  In
either case, the terms of the Advisory Agreement and continuance thereof must be
approved  by the vote of a  majority  of  Independent  Trustees  in  person at a
meeting  called  for the  purpose  of  voting  on such  approval.  The  Advisory
Agreement may be terminated as to any Fund, without penalty, on 60 days' written
notice by the FUND or Keystone, or may be terminated as to a Fund by a vote of a
majority  of the shares of such Fund.  The  Advisory  Agreement  will  terminate
automatically upon its assignment.

  The FUND has  adopted  a Code of Ethics  incorporating  policies  on  personal
securities trading as recommended by the Investment Company Institute.

FUND EXPENSES

  Each Fund will pay all of its expenses. In addition to the investment advisory
and management fees discussed  above,  the principal  expenses that each Fund is
expected to pay include,  but are not limited to, transfer,  dividend disbursing
and  shareholder  servicing  agent  costs  and  expenses;  custodian  costs  and
expenses;  its  pro  rata  portion  of  certain  Trustees'  fees,  fees  of  its
independent auditors,  fees of the FUND's legal counsel and legal counsel to the
FUND's  Board of  Trustees,  fees  payable  to  government  agencies,  including
registration  and  qualification  fees of the FUND,  the Funds and their  shares
under federal and state securities laws; and certain extraordinary  expenses. In
addition,  each  class  of  shares  of a Fund  will  pay  all  of  the  expenses
attributable  to it. Such expenses are currently  limited to  Distribution  Plan
expenses.  Each Fund also pays its brokerage  commissions,  interest charges and
taxes and certain extraordinary expenses.

  Until December 31, 1995, Keystone has voluntarily agreed to limit the expenses
of the FUND's Class A, B, and C shares to 0.75%,  1.50%, and 1.50%, of each such
class's  respective average daily net assets.  Thereafter,  a redetermination of
whether to continue these expense limitations and, if so, at what rates, will be
made.

  Keystone  will not be  required to make such  reimbursements  to the extent it
would result in a Fund's inability to qualify as a regulated  investment company
under the Code. In accordance  with certain  voluntary  expense  limitations  in
place  during the fiscal  year ended March 31,  1995,  Keystone  reimbursed  the
Florida,  Pennsylvania,  Texas,  Massachusetts  and New York  Insured  Funds (1)
$89,179,  $91,489, $35,517, $26,169 and $22,366,  respectively,  with respect to
each Fund's Class A shares; (2) $68,953, $81,415, $38,490, $64,511, and $85,602,
respectively,  with  respect to each  Fund's  Class B shares;  and (3)  $31,739,
$27,453,  $10,643,  $24,181,  and  $18,786,  respectively,  with respect to each
Fund's  Class C shares.  Keystone  does not intend to seek  repayment  for these
amounts.

  Each Fund may be subject to certain annual state expense limitations.

  During the fiscal year ended March 31,  1995,  the Florida,  Pennsylvania  and
Texas Funds paid or accrued to Keystone Investor Resource Center, Inc. ("KIRC"),
the FUND's  transfer and dividend  disbursing  agent,  $116,367,  $108,073,  and
$6,215,  respectively,  for shareholder  services.  During the fiscal year ended
March 31, 1995,  the  Massachusetts  and New York Insured  Funds paid or accrued
$25,831  and  $15,568 to KIRC for  shareholder  services.  During the year ended
March 31, 1995, the Florida,  Pennsylvania,  Texas,  Massachusetts  and New York
Insured Funds paid or accrued to KIRC and Keystone Investments $13,052, $20,909,
$13,870,  $17,498  and  $17,698,  respectively,  as  reimbursement  for  certain
accounting services. KIRC is a wholly-owned subsidiary of Keystone.

  For the fiscal year ended March 31,  1995,  the Class A, B and C shares of the
Florida,  Pennsylvania  and Texas  Funds  each  paid  0.75%,  1.50%  and  1.50%,
respectively, of each Fund's average net assets in expenses.

  For the fiscal year ended March 31,  1995,  the Class A, B and C shares of the
Massachusetts  Fund paid 0.46%,  1.24% and 1.23%,  respectively,  of average net
assets in expenses. For the fiscal year ended March 31, 1995, the Class A, B and
C shares of the New York Insured Fund paid 0.50%, 1.25% and 1.26%, respectively,
of average net assets in expenses.

  The foregoing expenses are net of expense  reimbursements  made by Keystone in
connection  with  voluntary  expense   limitations.   See  also  the  "Financial
Highlights" tables beginning on page 8 of this prospectus.

PORTFOLIO MANAGER

  Betsy A. Blacher,  a Keystone  Senior Vice  President and Group Head, has been
primarily  responsible  for the  management  of each of the  Funds  since  their
inception and is responsible for the day-to-day  management of the Florida Fund.
Ms Blacher has more than 16 years of investment experience.

  Daniel A. Rabasco, a Keystone Vice President and Portfolio  Manager,  has been
responsible for the day-to-day  management of the Pennsylvania,  Texas, New York
Insured and  Massachusetts  Funds since May 1, 1994. Mr. Rabasco has more than 7

SECURITIES TRANSACTIONS

  Under  policies  established  by  the  Board  of  Trustees,  Keystone  selects
broker-dealers to execute transactions subject to the receipt of best execution.
When selecting  broker-dealers  to execute  portfolio  transactions  for a Fund,
Keystone may follow a policy of  considering as a factor the number of shares of
the Fund  sold by such  broker-dealer.  In  addition,  broker-dealers  executing
portfolio  transactions  from  time to time may be  affiliated  with  the  FUND,
Keystone, the FUND's principal underwriter or their affiliates.

  A Fund may pay higher  commissions  to  broker-dealers  that provide  research
services.  Keystone  may use these  services  in  advising  a Fund as well as in
advising its other clients.

PORTFOLIO TURNOVER

  For the fiscal year ended March 31, 1994,  the turnover rates for the Florida,
Pennsylvania and Texas Funds were 113%, 37% and 56%, respectively.

  For the fiscal year ended March 31, 1995, the portfolio turnover rates for the
Florida, Pennsylvania and Texas Funds were 129%, 97% and 58%, respectively.

  For the fiscal year ended March 31, 1995, the portfolio turnover rates for the
Massachusetts and New York Insured Funds were 77% and 77%, respectively.

HOW TO BUY SHARES

  Shares of each Fund may be purchased from any broker-dealer that has a selling
agreement with the Keystone  Investment  Distributors  Company  (formerly  named
Keystone Distributors, Inc.) (the "Principal Underwriter"), the Fund's principal
underwriter.  The Principal Underwriter is a wholly-owned subsidiary of Keystone
and is located at 200 Berkeley Street, Boston, Massachusetts 02116-5034.

  In  addition,  you may open an account for the purchase of shares of a Fund by
mailing to the FUND, c/o KIRC, P.O. Box 2121, Boston, Massachusetts 02106- 2121,
a completed  account  application  and a check payable to the FUND. You may also
open an account by telephoning 1-800-343-2898 to obtain the number of an account
to which you can wire or electronically  transfer funds. You must then send in a
completed  account  application.  Subsequent  investments in Fund shares, in any
amount,  may be made by check, by wiring federal funds or by an electronic funds
transfer ("EFT").

  Orders for the  purchase of shares of a Fund will be  confirmed at an offering
price equal to the net asset value per share next  determined  after  receipt of
the order in proper form by the Principal Underwriter (generally as of the close
of the Exchange on that day) plus, in the case of Class A shares, the applicable
sales  charge.  Orders  received by dealers or other firms prior to the close of
the Exchange and received by the Principal Underwriter prior to the close of its
business day will be confirmed at the offering  price  effective as of the close
of the  Exchange on that day. The FUND  reserves the right to determine  the net
asset value more  frequently  than once a day if deemed  desirable.  Dealers and
other financial services firms are obligated to transmit orders promptly.

  Orders for shares of a Fund  received  other than as stated above will receive
the  offering  price  equal to the net asset  value per  share  next  determined
(generally the next business day's offering  price) plus, in the case of Class A
shares, the applicable sales charge.

  Your initial purchase must be at least $1,000.  There is no minimum amount for
subsequent purchases.

  Shares become entitled to income distributions  declared on the first business
day following  receipt by KIRC of payment for the shares.  It is the  investor's
responsibility to see that his dealer promptly forwards payment to the Principal
Underwriter for shares being purchased through the dealer.

  The FUND  reserves the right to withdraw all or any part of the offering  made
by this prospectus and to reject purchase orders.

  Shareholder  inquiries  should be directed to KIRC by calling toll free 1-800-
343-2898  or  writing  to KIRC or to the  firm  from  which  you  received  this
prospectus.

ALTERNATIVE SALES OPTIONS
  Generally, each Fund offers three classes of shares:

CLASS A SHARES -- FRONT END LOAD OPTION
  Class A shares are sold with a sales charge at the time of  purchase.  Class A
shares are not subject to a deferred sales charge when they are redeemed  except
as follows: Class A shares purchased on or after April 10, 1995 (1) in an amount
equal to or exceeding $1,000,000 or (2) by a corporate qualified retirement plan
or a non-qualified  deferred compensation plan sponsored by a corporation having
100 or more eligible  employees (a "Qualifying  Plan"), in either case without a
front end sales charge,  will be subject to a contingent  deferred  sales charge
for the 24 month period  following the date of purchase.  Certain Class A shares
purchased prior to April 10, 1995 may be subject to a deferred sales charge upon
redemption during the one year period following the date of purchase.

CLASS B SHARES -- BACK END LOAD OPTION
  Class B shares are sold without a sales  charge at the time of  purchase,  but
are, with certain  exceptions,  subject to a contingent deferred sales charge if
they are redeemed. Class B shares purchased on or after June 1, 1995 are subject
to a deferred sales charge upon redemption  during the 72 month period following
the  month of  purchase.  Class B  shares  purchased  prior to June 1,  1995 are
subject to a deferred  sales  charge upon  redemption  during the four  calendar
years following purchase. Class B shares purchased on or after June 1, 1995 that
have been  outstanding  for eight years  following  the month of  purchase  will
automatically  convert to Class A shares  without the  imposition of a front-end
sales charge or exchange  fee.  Class B shares  purchased  prior to June 1, 1995
will retain their existing conversion rights.

CLASS C SHARES -- LEVEL LOAD OPTION
  Class C shares are sold without a sales  charge at the time of  purchase,  but
are  subject to a deferred  sales  charge if they are  redeemed  within one year
after the date of purchase.  Class C shares are available  only through  dealers
who have  entered  into  special  distribution  agreements  with  the  Principal
Underwriter.

  Class A and B shares,  pursuant to their Distribution Plans,  currently pay an
annual service fee of 0.15% of the Fund's average daily net assets  attributable
to that  class,  and Class C shares  pay an annual  service  fee of 0.25% of the
Fund's  average  daily net assets  attributable  to Class C. In  addition to the
service fee, the Class B and Class C Distribution  Plans provide for the payment
of an annual  distribution  fee of up to 0.75% of the  average  daily net assets
attributable to their respective classes.

  Investors who would rather pay the entire cost of  distribution at the time of
investment,  rather than  spreading the cost over time,  might  consider Class A
shares.  Other investors might consider Class B or Class C shares, in which case
100% of the purchase price is invested  immediately,  depending on the amount of
the purchase and the length of investment.

  The Fund will not normally accept any purchase of Class B shares in the amount
of $250,000 or more and will not normally  accept any purchase of Class C shares
in the amount of $1,000,000 or more.

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

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

  Purchases  of a Fund's  Class A shares  in the  amount of $1  million  or more
and/or  purchases  of Class A shares  made by a  Qualifying  Plan will be at net
asset  value  without the  imposition  of a front-end  sales  charge  (each such
purchase, an "NAV Purchase").

  With respect to NAV  Purchases,  the  Principal  Underwriter  will pay broker/
dealers or others concessions based on (1) the investor's  cumulative  purchases
during the one-year  period  beginning with the date of the initial NAV Purchase
and (2) the investor's  cumulative  purchases  during each  subsequent  one-year
period  beginning  with the first NAV  Purchase  following  the end of the prior
period.  For such  purchases,  concessions  will be paid at the following  rate:
0.50% of the investment  amount up to  $4,999,999,  plus 0.25% of the investment
amount over $4,999,999.

  Class A shares  acquired  on or after April 10,  1995 in an NAV  Purchase  are
subject to a contingent  deferred sales charge of 0.50% upon  redemption  during
the 24 month period commencing on the date the shares were originally purchased.
Certain Class A shares purchased without a front-end sales charge prior to April
10,  1995 are  subject  to a  contingent  deferred  sales  charge of 0.25%  upon
redemption  during the one-year  period  commencing on the date such shares were
originally purchased.

  The sales charge is paid to the Principal Underwriter,  which in turn normally
reallows  a portion  to your  broker-dealer.  In  addition,  your  broker-dealer
currently will be paid periodic service fees at an annual rate of up to 0.15% of
the average daily net asset value of Class A shares maintained by such recipient
outstanding on the books of the FUND for specified periods.

  Upon  written  notice to  dealers  with  whom it has  dealer  agreements,  the
Principal Underwriter may reallow up to the full applicable sales charge.

  Initial  sales   charges  may  be  reduced  or   eliminated   for  persons  or
organizations  purchasing  Class A shares of a Fund alone or in combination with
Class  A  shares  of  other  Keystone  America  Funds.  See  Exhibit  B to  this
prospectus.  Initial sales charges may also be eliminated for persons purchasing
Class A shares that are included in a managed fee based program  (wrap  account)
through  broker  dealers  who have  entered  into  special  agreements  with the
Principal Underwriter.

  Upon prior  notification to the Principal  Underwriter,  Class A shares may be
purchased at net asset value by clients of registered representatives within six
months after a change in the registered representative's  employment,  where the
amount  invested  represents  redemption  proceeds  from a  registered  open-end
management  investment  company  not  distributed  or managed by Keystone or its
affiliates; and the shareholder either (1) paid a front end sales charge, or (2)
was at some time  subject to, but did not actually  pay, a  contingent  deferred
sales charge with respect to the redemption proceeds.

  In  addition,  since  January 1, 1995 and through June 30, 1995 and upon prior
notification  to the Principal  Underwriter,  Class A shares may be purchased at
net asset value by clients of registered representatives within six months after
the  redemption  of shares of any  registered  open-end  investment  company not
distributed or managed by Keystone or its affiliates,  where the amount invested
represents   redemption   proceeds  from  such  unrelated   registered  open-end
investment  company,  and the  shareholder  either  (1) paid a front  end  sales
charge,  or (2) was at some  time  subject  to,  but did  not  actually  pay,  a
contingent deferred sales charge with respect to the redemption proceeds.

CLASS A DISTRIBUTION PLAN

  Each Fund has adopted a  Distribution  Plan with respect to its Class A shares
(the "Class A Distribution  Plan") that provides for  expenditures  by the Fund,
currently  limited to 0.15%  annually  of the  average  daily net asset value of
Class A shares, in connection with the distribution of Class A shares.  Payments
under  each  Class A  Distribution  Plan  are  currently  made to the  Principal
Underwriter  (which may  reallow  all or part to  others,  such as  dealers)  as
service  fees at an annual  rate of up to 0.15% of the  average  daily net asset
value of Class A shares maintained by the recipients outstanding on the books of
the Fund for specified periods.

CLASS B SHARES

  Class B shares are  offered  at net asset  value,  without  an  initial  sales
charge.

  With respect to Class B shares  purchased on or after June 1, 1995, each Fund,
with certain exceptions,  imposes a deferred sales charge in accordance with the
following schedule:

                                                                DEFERRED
                                                                 SALES
                                                                 CHARGE
REDEMPTION TIMING                                                IMPOSED
- -----------------                                                -------

First twelve month period following month of purchase .......     5.00%
Second twelve month period following month of purchase ......     4.00%
Third twelve month period following month of purchase .......     3.00%
Fourth twelve month period following month of purchase ......     3.00%
Fifth twelve month period following month of purchase .......     2.00%
Sixth twelve month period following month of purchase .......     1.00%

No deferred sales charge is imposed on amounts redeemed thereafter.

  With  respect to Class B shares  sold prior to June 1, 1995,  each Fund,  with
certain exceptions,  imposes a deferred sales charge of 3.00% on shares redeemed
during the calendar year of purchase and the first  calendar year after the year
of purchase;  2.00% on shares redeemed during the second calendar year after the
year of purchase;  and 1.00% on shares  redeemed  during the third calendar year
after the year of  purchase.  No  deferred  sales  charge is  imposed on amounts
redeemed thereafter.

  When  imposed,  the  deferred  sales  charge is deducted  from the  redemption
proceeds  otherwise payable to you. The deferred sales charge is retained by the
Principal  Underwriter.  Amounts received by the Principal Underwriter under the
Class B Distribution Plans are reduced by deferred sales charges retained by the
Principal Underwriter. See "Contingent Deferred Sales Charge and Waiver of Sales
Charges" below.

  Class B shares  purchased on or after June 1, 1995 that have been  outstanding
for eight years  following the month of purchase will  automatically  convert to
Class A shares (which are subject to a lower  Distribution  Plan charge) without
imposition of a front-end sales charge or exchange fee. Class B shares purchased
prior to June 1, 1995  will  similarly  convert  to Class A shares at the end of
seven calendar  years after the year of purchase.  (Conversion of Class B shares
represented  by  stock  certificates  will  require  the  return  of  the  stock
certificates to KIRC.) The Class B shares so converted will no longer be subject
to the higher expenses borne by Class B shares.  Because the net asset value per
share of the Class A shares may vary from that of the Class B shares at the time
of  conversion,  although the dollar value will be the same, a  shareholder  may
receive  more or  fewer  Class A  shares  than  the  number  of  Class B  shares
converted.  Under  current law, it is the FUND's  opinion that such a conversion
will not  constitute a taxable event under federal  income tax law. In the event
that this  ceases  to be the case,  the Board of  Trustees  will  consider  what
action,  if  any,  is  appropriate  and in the  best  interests  of the  Class B
shareholders.

CLASS B DISTRIBUTION PLANS

  Each Fund has adopted  Distribution  Plans with  respect to its Class B shares
(the "Class B Distribution  Plans") that provide for expenditures by the Fund at
an annual  rate of up to 1.00% of the  average  daily net asset value of Class B
shares (currently limited to 0.90%) to pay expenses of the distribution of Class
B shares.  Payments under the Class B  Distribution  Plans are currently made to
the  Principal  Underwriter  (which may reallow  all or part to others,  such as
dealers)  (1) as  commissions  for  Class B shares  sold and (2) as  shareholder
service fees. Amounts paid or accrued to the Principal Underwriter under (1) and
(2) in the aggregate may not exceed the annual limitation referred to above.

  The Principal Underwriter generally reallows to brokers or others a commission
equal to 4.00% of the  price  paid for each  Class B share  sold  plus the first
year's  service fee in advance in the amount of 0.15% of the price paid for each
Class B share sold.  Beginning  approximately  12 months after the purchase of a
Class B share,  the broker or other party will receive service fees at an annual
rate of  0.15% of the  average  daily  net  asset  value  of such  Class B share
maintained by the recipient  outstanding  on the books of the Fund for specified
periods. See "Distribution Plans" below.

  With respect to the FUND's Class B shares only, for the period June 1, 1995 to
August 31, 1995, the Principal  Underwriter will reallow an increased commission
equal  to  4.85%  of the  price  paid  for  each  Class  B share  sold to  those
broker/dealers or others who allow their individual  selling  representatives to
participate in the additional 0.85% commission.

CLASS C SHARES

  Class C shares are offered only through dealers who have special  distribution
agreements  with the  Principal  Underwriter.  Class C shares are offered at net
asset value, without an initial sales charge. With certain exceptions, each Fund
may impose a deferred sales charge of 1.00% on shares  redeemed  within one year
after the date of  purchase.  No  deferred  sales  charge is  imposed on amounts
redeemed thereafter.  If imposed, the deferred sales charge is deducted from the
redemption  proceeds  otherwise  payable to you.  The  deferred  sales charge is
retained by the Principal Underwriter. See "Contingent Deferred Sales Charge and
Waiver of Sales Charges" below.

CLASS C DISTRIBUTION PLAN

  Each Fund has adopted a  Distribution  Plan with respect to its Class C shares
(the "Class C Distribution  Plan") that provides for  expenditures  at an annual
rate of up to 1.00%  of the  average  daily  net  asset  value of Class C shares
(currently  limited to 0.90%) to pay  expenses  of the  distribution  of Class C
shares.  Payments under the Class C Distribution  Plan are currently made to the
Principal Underwriter (which may reallow all or part to others, such as dealers)
(1) as commissions for Class C shares sold and (2) as shareholder  service fees.
Amounts paid or accrued to the  Principal  Underwriter  under (1) and (2) in the
aggregate may not exceed the annual limitation  referred to above. The Principal
Underwriter  generally  reallows to brokers or others a commission in the amount
of 0.75% of the price paid for each Class C share  sold,  plus the first  year's
service fee in advance in the amount of 0.25% of the price paid for each Class C
share sold,  and,  beginning  approximately  fifteen  months after  purchase,  a
commission  at  an  annual  rate  of  0.75%   (subject  to  NASD  rules  --  see
"Distribution   Plans")   plus  service  fees  at  the  annual  rate  of  0.25%,
respectively,  of the  average  daily  net  asset  value  of each  Class C share
maintained by the recipients  outstanding on the books of the Fund for specified
periods. See "Distribution Plans" below.

CONTINGENT DEFERRED SALES CHARGE AND WAIVER OF SALES CHARGES

  Any  contingent  deferred sales charge imposed upon the redemption of Class A,
Class B or Class C shares  is a  percentage  of the  lesser of (1) the net asset
value of the shares  redeemed  or (2) the net asset value at time of purchase of
such  shares.  No  contingent  deferred  sales  charge is imposed  when  amounts
redeemed are derived from (1) increases in the value of an account above the net
cost of such  shares due to  increases  in the net asset value per share of such
shares; (2) certain shares with respect to which a Fund did not pay a commission
on issuance,  including shares acquired through  reinvestment of dividend income
and capital gains  distributions;  (3) certain Class A shares held for more than
one year or two years, as the case may be, from the date of purchase;  (4) Class
B shares held during more than four  consecutive  calendar years or more than 72
months  after the month of  purchase,  as the case may be; or (5) Class C shares
held for more than one year from date of purchase.  Upon request for redemption,
shares not  subject to the  contingent  deferred  sales  charge will be redeemed
first. Thereafter, shares held the longest will be the first to be redeemed.

  Each Fund may also sell Class A, Class B or Class C shares at net asset  value
without  any initial  sales  charge or a  contingent  deferred  sales  charge to
certain Directors, Trustees, officers and employees of the Fund and Keystone and
certain of their affiliates, to registered  representatives of firms with dealer
agreements with the Principal  Underwriter and to a bank or trust company acting
as a trustee for a single account.

  With respect to Class A shares  purchased  by a  Qualifying  Plan at net asset
value or Class C shares purchased by a Qualifying  Plan, no contingent  deferred
sales  charge  will  be  imposed  on any  redemptions  made  specifically  by an
individual  participant in the Qualifying  Plan. This waiver is not available in
the  event a  Qualifying  Plan (as a  whole)  redeems  substantially  all of its
assets.

  In addition, no contingent deferred sales charge is imposed on a redemption of
shares of a Fund in the event of (1) death or disability of the shareholder; (2)
a lump-sum distribution from a 401(k) plan or other benefit plan qualified under
the Employee  Retirement  Income Security Act of 1974  ("ERISA");  (3) automatic
withdrawals  from ERISA plans if the  shareholder  is at least 59 1/2 years old;
(4)  involuntary  redemptions of accounts having an aggregate net asset value of
less than $1,000; (5) automatic  withdrawals under an automatic  withdrawal plan
of up to 1 1/2% per month of the  shareholder's  initial  account  balance;  (6)
withdrawals  consisting of loan proceeds to a retirement plan  participant;  (7)
financial  hardship  withdrawals made by a retirement plan  participant;  or (8)
withdrawals  consisting of returns of excess  contributions  or excess  deferral
amounts made to a retirement plan participant.


ARRANGEMENTS WITH BROKER-DEALERS AND OTHERS

  From  time  to  time,  the  Principal   Underwriter  may  provide  promotional
incentives,  including  reallowance of up to the entire sales charge, to certain
dealers  whose  representatives  have sold or are  expected to sell  significant
amounts  of a  Fund.  In  addition,  from  time to  time,  dealers  may  receive
additional  cash  payments.   The  Principal  Underwriter  may  provide  written
information to dealers with whom it has dealer  agreements that relates to sales
incentive campaigns conducted by such dealers for their  representatives as well
as financial  assistance in connection with pre-approved  seminars,  conferences
and advertising.  No such programs or additional compensation will be offered to
the extent they are  prohibited by the laws of any state or any  self-regulatory
agency such as the National  Association of Securities  Dealers,  Inc. ("NASD").
Dealers  to whom  substantially  the  entire  sales  charge on Class A shares is
reallowed  may be deemed to be  underwriters  as that term is defined  under the
Securities Act of 1933.

  The Principal Underwriter may, at its own expense, pay concessions in addition
to those described above to dealers that satisfy  certain  criteria  established
from  time to time by the  Principal  Underwriter.  These  conditions  relate to
increasing  sales of shares of the  Keystone  funds over  specified  periods and
certain other factors. Such payments may, depending on the dealer's satisfaction
of the required  conditions,  be periodic and may be up to 0.25% of the value of
shares sold by such dealer.

  The Principal  Underwriter  may also pay a transaction fee (up to the level of
payments allowed to dealers for the sale of shares, as described above) to banks
and other financial  services firms that facilitate  transactions in shares of a
Fund for their clients. The Glass-Steagall Act currently limits the ability of a
depository  institution  (such  as a  commercial  bank  or a  savings  and  loan
association) to become an underwriter or distributor of securities. In the event
the  Glass-Steagall  Act is  deemed to  prohibit  depository  institutions  from
accepting  payments under the  arrangement  described  above, or should Congress
relax current  restrictions  on depository  institutions,  the Board of Trustees
will consider what action, if any, is appropriate.

  In  addition,  state  securities  laws on  this  issue  may  differ  from  the
interpretations  of  federal  law  expressed  herein,  and banks  and  financial
institutions may be required to register as dealers pursuant to state law.

DISTRIBUTION PLANS

  As  discussed  above,  each Fund bears some of the costs of selling its shares
under  Distribution Plans adopted with respect to its Class A, Class B and Class
C shares pursuant to Rule 12b-1 under the 1940 Act.

  The  NASD  currently  limits  the  amount  that a Fund  may  pay  annually  in
distribution costs for the sale of its shares and shareholder  service fees. The
rule limits annual  expenditures to 1% of the aggregate  average daily net asset
value of its shares, of which 0.75% may be used to pay such  distribution  costs
and 0.25% may be used to pay shareholder  service fees. The NASD also limits the
aggregate  amount  that a Fund may pay for such  distribution  costs to 6.25% of
gross  share  sales  since the  inception  of a 12b-1  Distribution  Plan,  plus
interest at the prime rate plus 1% on such amounts (less any contingent deferred
sales  charges paid by  shareholders  to the  Principal  Underwriter)  remaining
unpaid from time to time.

  The Principal Underwriter intends, but is not obligated, to continue to pay or
accrue distribution charges incurred in connection with the Class B Distribution
Plans that  exceed  current  annual  payments  permitted  to be  received by the
Principal  Underwriter  from a Fund. The Principal  Underwriter  intends to seek
full payment of such charges from a Fund (together with annual interest  thereon
at the prime  rate plus one  percent)  at such time in the future as, and to the
extent that, payment thereof by a Fund would be within the permitted limits.

  If the FUND's Independent  Trustees authorize such payments,  the effect would
be to extend the period of time during which the FUND incurs the maximum  amount
of costs allowed by a Distribution  Plan. If a Distribution  Plan is terminated,
the Principal  Underwriter  will ask the  Independent  Trustees to take whatever
action they deem appropriate under the circumstances  with respect to payment of
such amounts.

  In connection  with financing its  distribution  costs,  including  commission
advances  to  dealers  and  others,  the  Principal  Underwriter  has  sold to a
financial  institution  substantially all of its 12b-1 fee collection rights and
contingent  deferred sales charge collection rights in respect of Class B shares
sold during the two-year period commencing  approximately June 1, 1995. The FUND
has  agreed  not to reduce  the rate of payment of 12b-1 fees in respect of such
Class B shares unless it terminates such shares'  Distribution  Plan completely.
If it terminates  such  Distribution  Plan,  the FUND may be subject to possible
adverse distribution consequences.

  Each of the  Distribution  Plans may be  terminated at any time by vote of the
Independent  Trustees or by vote of a majority of the outstanding  voting shares
of the respective class.

  For the  Florida,  Pennsylvania,  Texas,  Massachusetts  and New York  Insured
Funds,  unreimbursed  Class B Distribution  Plan expenses at March 31, 1995 were
$3,196,058  (6.26%  of Class B net  assets),  $1,923,455  (6.27%  of Class B net
assets),  $145,495 (6.73% of Class B net assets), $384,672 (6.24% of Class B net
assets), and $728,940 (6.12% of Class B net assets), respectively.

  For  the  year  ended  March  31,  1995,  the  Florida,  Pennsylvania,  Texas,
Massachusetts  and New York Insured  Funds paid the  Principal  Underwriter  (1)
$66,246,  $44,697,  $2,847, $1,829, and $3,025,  respectively,  pursuant to each
Fund's Class A Distribution Plan; (2) $345,221,  $244,404, $18,613, $40,387, and
$70,227,  respectively,  pursuant to each Fund's Class B Distribution  Plan; and
(3) $140,405, $81,781, $5,377, $15,014, and $15,895,  respectively,  pursuant to
each Fund's Class C Distribution Plan.

  Dealers or others may receive  different  levels of compensation  depending on
which class of shares they sell.  Payments  pursuant to a Distribution  Plan are
included in the operating expenses of the class.

HOW TO REDEEM SHARES

  Your shares of a Fund may be  redeemed  for cash at their net asset value upon
written order by you to the FUND,  c/o KIRC, and  presentation  to the FUND of a
properly  endorsed share  certificate  if  certificates  have been issued.  Your
signature(s)  on the  written  order  and  certificates  must be  guaranteed  as
described  below.  In order to redeem  by  telephone  or to engage in  telephone
transactions   generally,   you  complete  the  authorization  in  your  account
application.  Proceeds for shares redeemed by telephonic order will be deposited
by wire or EFT only to the bank account designated in your account application.

  The redemption  value equals the net asset value per share then determined and
may be more or less than your cost  depending  upon  changes in the value of the
Fund's portfolio securities between purchase and redemption.

  If imposed, the deferred sales charge is deducted from the redemption proceeds
otherwise payable to you.

  At various times,  the FUND may be requested to redeem shares for which it has
not yet received good payment. In such a case, the FUND will mail the redemption
proceeds upon clearance of the purchase  check,  which may take up to 15 days or
more. Any delay may be avoided by purchasing shares with a certified check drawn
on a U.S.  bank or by bank wire of funds.  Although  the mailing of a redemption
check or the wiring of redemption proceeds may be delayed,  the redemption value
will be  determined  and the  redemption  processed  in the  ordinary  course of
business upon-receipt of proper documentation.  In such a case, after redemption
and prior to the release of the proceeds,  no appreciation or depreciation  will
occur in the value of the redeemed  shares,  and no interest will be paid on the
redemption proceeds. If the mailing of redemption proceeds has been delayed, the
check will be mailed or the proceeds  wired promptly after good payment has been
collected.

  The FUND  computes  the amount due you at the close of the Exchange at the end
of the day on which it has received all proper  documentation  from you. Payment
of the amount due on redemption  less any applicable  contingent  deferred sales
charge (as described above) will be made within seven days thereafter  except as
discussed herein.

  You  may  also  redeem  your  shares  through  broker-dealers.  The  Principal
Underwriter,  acting as agent for the FUND,  stands ready to repurchase a Fund's
shares upon orders from dealers at the redemption value described above computed
on the day the  Principal  Underwriter  receives  the  order.  If the  Principal
Underwriter  has  received  proper  documentation,  it will  pay the  redemption
proceeds to the  broker-dealer  placing the order within seven days  thereafter.
The Principal Underwriter charges no fees for this service.
However, your broker-dealer may do so.

  For your protection,  SIGNATURES ON CERTIFICATES, STOCK POWERS AND ALL WRITTEN
ORDERS OR  AUTHORIZATIONS  MUST BE GUARANTEED BY A U.S. STOCK EXCHANGE MEMBER, A
U.S.  COMMERCIAL  BANK OR TRUST COMPANY OR OTHER  PERSONS  ELIGIBLE TO GUARANTEE
SIGNATURES  UNDER THE SECURITIES ACT OF 1934 AND KIRC'S  POLICIES.  The FUND and
KIRC may waive this requirement,  but may also require  additional  documents in
certain cases.  Currently,  the requirement  for a signature  guarantee has been
waived on redemptions of $50,000 or less where the account address of record has
been the same for a minimum  period of 30 days.  The FUND and KIRC  reserve  the
right to withdraw this waiver at any time.

  If the FUND receives a redemption  order,  but you have not clearly  indicated
the amount of money or number of shares of the Fund  involved,  the FUND  cannot
execute the order. In such cases, the FUND will request the missing  information
from you and process the order on the day such information is received.

TELEPHONE

  Under ordinary  circumstances,  you may redeem up to $50,000 from your account
by telephone by calling toll free 1-800-343-2898.

  In order to insure that  instructions  received  by KIRC are genuine  when you
initiate a telephone  transaction,  you will be asked to verify certain criteria
specific to your  account.  At the  conclusion of the  transaction,  you will be
given a transaction number confirming your request,  and written confirmation of
your   transaction  will  be  mailed  the  next  business  day.  Your  telephone
instructions will be recorded.  Redemptions by telephone are allowed only if the
address and bank account of record have been the same for a minimum period of 30
days.

  If the redemption proceeds are less than $2,500, they will be mailed by check.
If they are $2,500 or more,  they will be  mailed,  wired or sent by EFT to your
previously  designated bank account as you direct. If you do not specify how you
wish your redemption proceeds to be sent, they will be mailed by check.

  If you cannot reach the FUND by telephone,  you should  follow the  procedures
for redeeming by mail or through a broker as set forth herein.

SMALL ACCOUNTS

  Due to the high cost of  maintaining  small  accounts,  the FUND  reserves the
right to redeem your account if its value has fallen below  $1,000,  the current
minimum  investment  level, as a result of your redemptions (but not as a result
of market  action).  You will be  notified  in  writing  and  allowed 60 days to
increase the value of your account to the minimum investment level.

REDEMPTIONS IN KIND

  If conditions arise that would make it undesirable for the FUND to pay for all
redemptions  in cash,  the FUND may  authorize  payment to be made in  portfolio
securities or other property. The FUND has obligated itself,  however, under the
1940 Act to redeem for cash all shares of a Fund presented for redemption by any
one  shareholder  in any 90-day period up to the lesser of $250,000 or 1% of the
Fund's net  assets.  Securities  delivered  in payment of  redemptions  would be
valued at the same value  assigned to them in computing  the net asset value per
share  and,  to the  extent  permitted  by law,  would  be  readily  marketable.
Shareholders  receiving such  securities  would incur brokerage costs when these
securities are sold.

GENERAL

  The FUND  reserves the right at any time to  terminate,  suspend or change the
terms of any redemption  method described in this prospectus,  except redemption
by mail,  and to impose or change fees including fees for services in connection
with exchanges.

  Except  as  otherwise  noted,   neither  the  FUND,  KIRC  nor  the  Principal
Underwriter  assumes  responsibility  for the  authenticity of any  instructions
received  by any of them  from a  shareholder  in  writing,  over  the  Keystone
Automated  Response Line ("KARL") or by telephone.  KIRC will employ  reasonable
procedures to confirm that  instructions  received over KARL or by telephone are
genuine.  Neither the FUND,  KIRC nor the Principal  Underwriter  will be liable
when  following  instructions  received  over  KARL or by  telephone  that  KIRC
reasonably believes to be genuine.

  The FUND may  temporarily  suspend the right to redeem its shares when (1) the
Exchange is closed,  other than  customary  weekend and  holiday  closings;  (2)
trading on the  Exchange is  restricted;  (3) an  emergency  exists and the FUND
cannot dispose of its  investments or fairly  determine  their value; or (4) the
Securities and Exchange Commission so orders.

SHAREHOLDER SERVICES

  Details on all shareholder services may be obtained from KIRC by writing or by
calling toll free 1-800-343-2898.

KEYSTONE AUTOMATED RESPONSE LINE

  KARL offers you specific fund account  information and price, total return and
yield  quotations as well as the ability to do account  transactions,  including
investments, exchanges and redemptions. You may access KARL by dialing toll free
1-800-346-3858 on any touch-tone telephone, 24 hours a day, seven days a week.

EXCHANGES

  If you have obtained the appropriate prospectus,  you may exchange shares of a
Fund for shares of certain  other  Keystone  America  Funds and Keystone  Liquid
Trust ("KLT") as follows:

    Class A shares may be exchanged for Class A shares of other Keystone America
  Funds and Class A shares of KLT;

    Class B shares may be exchanged for the same type of Class B shares of other
  Keystone America Funds and the same type of Class B shares of KLT; and

    Class C shares may be exchanged for Class C shares of other Keystone America
  Funds and Class C shares of KLT.

The  exchange  of Class B shares  and Class C shares  will not be  subject  to a
contingent  deferred  sales charge.  However,  if the shares being  tendered for
exchange are

    (1) Class A shares acquired in an NAV Purchase or otherwise without a
front end sales charge,

    (2)  Class B shares  that  have  been  held for less  than 72 months or four
years, as the case may be, or

    (3) Class C shares that have been held for less than one year,

and are still subject to a deferred sales charge, such charge will carry over to
the shares being acquired in the exchange transaction.

  You may exchange shares by calling toll free
1-800-343-2898,  by writing KIRC or by calling KARL.  Shares  purchased by check
are  eligible  for  exchange  after  15 days.  There  is a  $10.00  fee for each
exchange.  If an exchange  order is made by an individual  investor  using KARL,
there is no fee. The FUND reserves the right, after providing  shareholders with
any required  notice to  shareholders,  to terminate  this exchange  offer or to
change its terms, including the right to change the fee for any exchange.

  Orders to exchange a certain  class of shares of a Fund for the  corresponding
class of shares of KLT will be executed by redeeming  the shares of the Fund and
purchasing  the  corresponding  class of shares of KLT at the net asset value of
KLT shares  next  determined  after the  proceeds  from such  redemption  become
available,  which may be up to seven days after  such  redemption.  In all other
cases, orders for exchanges received by the FUND prior to 4:00 p.m. eastern time
on any day the FUND is open for business will be executed at the  respective net
asset  values  determined  as of the  close of  business  that day.  Orders  for
exchanges  received  after 4:00 p.m.  eastern  time on any  business day will be
executed at the respective net asset values  determined at the close of the next
business day.

  An  excessive  number  of  exchanges  may  be  disadvantageous  to  the  FUND.
Therefore,  the FUND, in addition to its right to reject any exchange,  reserves
the right to terminate the exchange  privilege of any shareholder who makes more
than five  exchanges  of  shares  of the Funds in a year or three in a  calendar
quarter.

  An exchange  order must  comply  with the  requirements  for a  redemption  or
repurchase  order and must  specify  the dollar  value or number of shares to be
exchanged. Exchanges are subject to the minimum initial purchase requirements of
the Fund being acquired.  An exchange  constitutes a sale for federal income tax
purposes.

  The exchange  privilege  is available  only in states where shares of the Fund
being acquired may legally be sold.

KEYSTONE AMERICA MONEY LINE

  Keystone  America  Money Line  eliminates  the delay of mailing a check or the
expense of wiring  funds.  You must  request  the  service on your  application.
Keystone  America  Money Line allows you to  authorize  electronic  transfers of
money to  purchase  a Fund's  shares in any  amount  and to redeem up to $50,000
worth of a Fund's  shares.  You can use  Keystone  America  Money  Line  like an
"electronic  check" to move money  between your bank account and your account in
the FUND with one  telephone  call.  You must allow two business  days after the
call for the transfer to take place. For money recently invested, you must allow
normal check clearing time before redemption proceeds are sent to your bank.

  You may also arrange for systematic  monthly or quarterly  investments in your
Keystone America account.  Once proper authorization is given, your bank account
will be  debited  to  purchase  shares  in the Fund  specified  in your  account
application.  You will receive  confirmation from the Principal  Underwriter for
every transaction.

  To change the amount of or  terminate a Keystone  America  Money Line  service
(which could take up to 30 days), you must write to KIRC, P.O. Box 2121, Boston,
Massachusetts 02106-2121, and include your account number.

AUTOMATIC WITHDRAWAL PLAN

  Under an Automatic  Withdrawal Plan, if your account for a Fund's shares has a
value of at least  $10,000,  you may arrange for  regular  monthly or  quarterly
fixed withdrawal payments. Each payment must be at least $100 and may be as much
as 1.5% per month or 4.5% per  quarter of the total net asset  value of the Fund
shares in your account when the Automatic  Withdrawal Plan is opened.  Excessive
withdrawals  may decrease or deplete the value of your  account.  Because of the
effect of the  applicable  sales  charge,  a Class A  investor  should  not make
continuous  purchases  of a Fund's  shares while  participating  in an Automatic
Withdrawal Program.

DOLLAR COST AVERAGING

  Through  dollar cost averaging you can invest a fixed dollar amount each month
or each quarter in any Keystone  America Fund. This results in more shares being
purchased  when the selected  fund's net asset value is relatively low and fewer
shares being purchased when the fund's net asset value is relatively high, which
may cause a lower  average  cost per  share  than a less  systematic  investment
approach.

  Prior to participating in dollar cost averaging,  you must have established an
account in a Keystone  America Fund or a money market fund managed or advised by
Keystone.  You should  designate on the  application  the dollar  amount of each
monthly or quarterly  investment (minimum $100) you wish to make and the fund in
which  the  investment  is to be  made.  Thereafter,  on  the  first  day of the
designated  month  an  amount  equal  to  the  specified  monthly  or  quarterly
investment will automatically be redeemed from your initial account and invested
in shares of the designated fund. If you are a Class A investor and paid a sales
charge on your  initial  purchase,  the shares  purchased  will be eligible  for
Rights of Accumulation  and the sales charge  applicable to the purchase will be
determined  accordingly.  In  addition,  the value of shares  purchased  will be
included in the total amount required to fulfill a Letter of Intent.  If a sales
charge was not paid on the initial  purchase,  a sales charge will be imposed at
the time of subsequent  purchases and the value of shares  purchased will become
eligible for Rights of Accumulation and Letters of Intent.

TWO DIMENSIONAL INVESTING

  You may elect to have income and capital gains distributions from any class of
Keystone America Fund shares you may own automatically  invested to purchase the
same class of shares of any other  Keystone  America  Fund.  You may select this
service on the application and indicate the Keystone  America Fund(s) into which
distributions  are to be  invested.  The  value  of  shares  purchased  will  be
ineligible for Rights of  Accumulation  and Letters of Intent.  Two  dimensional
investing  is available  only in states where shares of the Fund being  acquired
may legally be sold.

OTHER SERVICES

  Under  certain  circumstances,  you may,  within 30 days  after a  redemption,
reinstate  your account in the same class of shares that you redeemed at current
net asset value.

PERFORMANCE DATA

  From time to time a Fund may advertise  "total return,"  "current yield" and a
"tax equivalent yield." ALL FIGURES ARE BASED ON HISTORICAL EARNINGS AND ARE NOT
INTENDED TO INDICATE  FUTURE  PERFORMANCE.  Total  return and current  yield are
computed separately for each class of shares of a Fund. Total return refers to a
Fund's  average  annual  compounded  rates  of  return  over  specified  periods
determined by comparing the initial amount invested in a particular class to the
ending  redeemable  value  of  that  amount.   The  resulting  equation  assumes
reinvestment  of all  dividends and  distributions  and deduction of the maximum
sales charge and all recurring  charges,  if any,  applicable to all shareholder
accounts. The exchange fee is not included in the calculation.

  Current yield  quotations  represent  the yield on an investment  for a stated
30-day period computed by dividing net investment income earned per share during
the base period by the maximum  offering  price per share on the last day of the
base period.  Such yield will include  income from sources other than  municipal
obligations, if any.

  Tax  equivalent  yield is, in general,  the current  yield divided by a factor
equal to one minus a stated  income  tax rate and  reflects  the yield a taxable
investment  would  have to  achieve  in order to equal on an  after-tax  basis a
tax-exempt yield.

  Any  given  yield  or  total  return   quotation   should  not  be  considered
representative of a Fund's yield or total return for any future period.

  The FUND may also include comparative  performance  information for each class
of shares when  advertising  or marketing the FUND's  shares,  such as data from
Lipper Analytical Services, Inc., Morningstar, Inc., S&P, Ibbotson Associates
or other industry publications.

FUND SHARES

  The FUND currently issues shares of five separate series evidencing  interests
in different portfolio securities,  and each Fund generally issues three classes
of  shares.  The FUND is  authorized  to issue  additional  series or classes of
shares.  Shares of a Fund  participate in dividends and  distributions  and have
equal voting,  liquidation and other rights with other shares of the Fund except
that (1) expenses related to the distribution of each class of shares,  or other
expenses that the Board of Trustees may designate as class  expenses,  from time
to time, are borne solely by each class;  (2) each class of shares has exclusive
voting  rights  with  respect  to its  Distribution  Plan;  (3) each  class  has
different  exchange  privileges;  and (4) each class  generally  has a different
designation.  When  issued  and paid for,  the shares of each Fund will be fully
paid and  nonassessable  by the FUND.  Shares of each Fund may be  exchanged  as
explained  under  "Shareholder  Services,"  but will  have no other  preference,
conversion,  exchange or preemptive rights. Shares are redeemable,  transferable
and freely assignable as collateral. There are no sinking fund provisions.


  Shareholders  of a Fund are entitled to one vote for each full share owned and
fractional  votes for  fractional  shares on all  matters  subject to Fund vote.
Shares of a Fund vote together except when required by law to vote separately by
class.  The FUND does not have  annual  meetings.  The FUND  will  have  special
meetings,  from time to time,  as required  under its  Declaration  of Trust and
under the 1940 Act. As provided in the FUND's Declaration of Trust, shareholders
have the right to remove  Trustees by an  affirmative  vote of two-thirds of the
outstanding  shares. A special meeting of the shareholders will be held when 10%
of the  outstanding  shares  request a meeting  for the  purpose  of  removing a
Trustee.  As prescribed by Section  16(c) of the 1940 Act,  shareholders  may be
eligible for shareholder communication assistance in connection with the special
meeting.


  Under  Massachusetts  law, it is possible that a FUND  shareholder may be held
personally liable for the FUND's  obligations.  The FUND's  Declaration of Trust
provides,  however,  that  shareholders  shall not be  subject  to any  personal
liability  for the FUND's  obligations  and provides  indemnification  from FUND
assets for any shareholder  held personally  liable for the FUND's  obligations.
Disclaimers of such liability are included in each Fund agreement.

                      ADDITIONAL INVESTMENT INFORMATION
                     CORPORATE AND MUNICIPAL BOND RATINGS

S&P CORPORATE AND MUNICIPAL BOND RATINGS

A.  MUNICIPAL NOTES

  An S&P note rating  reflects the  liquidity  concerns and market  access risks
unique to notes.  Notes due in three  years or less will  likely  receive a note
rating.  Notes maturing  beyond three years will most likely receive a long-term
debt rating. The following criteria are used in making that assessment:

  1. amortization schedule (the larger the final maturity relative to other
maturities the more likely it will be treated as a note); and

  2. source of payment (the more dependent the issue is on the market for its
refinancing, the more likely it will be treated as a note).

  Note ratings are as follows:

  1. SP-1 -- Strong capacity to pay principal and interest. Those issues
     determined to possess a very strong capacity to pay debt service are
     given a plus (+                              ) designation.

  2. SP-2 --  Satisfactory  capacity to pay principal  and  interest,  with some
     vulnerability  to adverse  financial and economic changes over the terms of
     the notes.

  3. SP-3 -- Speculative capacity to pay principal and interest.

B.  TAX EXEMPT DEMAND BONDS

  S&P assigns  "dual"  ratings to all long-term debt issues that have as part of
their provisions a demand or double feature.

  The first rating  addresses  the  likelihood  of  repayment  of principal  and
interest as due, and the second rating  addresses only the demand  feature.  The
long-term  debt  rating  symbols  are used for  bonds to  denote  the  long-term
maturity  and the  commercial  paper  rating  symbols are used to denote the put
option (for example, "AAA/A-1+ "). For the newer "demand notes," S&P note rating
symbols,  combined with the commercial paper symbols, are used (for example, "SP
- -- 1+ / A-1+ ").

C.  CORPORATE AND MUNICIPAL BOND RATINGS

  An S&P  corporate  or  municipal  bond rating is a current  assessment  of the
creditworthiness  of an  obligor,  including  obligors  outside  the U.S.,  with
respect to a specific  obligation.  This assessment may take into  consideration
obligors such as guarantors, insurers or lessees. Ratings of foreign obligors do
not take into account currency exchange and related  uncertainties.  The ratings
are based on current information furnished by the issuer or obtained by S&P from
other sources it considers reliable.

  The ratings are based, in varying degrees, on the following considerations:

    1. likelihood of default capacity and willingness of the obligor as to the
  timely payment of interest and repayment of principal in accordance with the
  terms of the obligation;

    2. nature of and provisions of the obligation; and

    3. protection afforded by and relative position of the obligation in the
  event of bankruptcy, reorganization or other arrangement under the laws of
  bankruptcy and other laws affecting creditors' rights.

  PLUS (+ ) OR MINUS  (-):  To  provide  more  detailed  indications  of  credit
quality, ratings from "AA" to "BBB" may be modified by the addition of a plus or
minus sign to show relative standing within the major rating categories.

  A  provisional  rating is  sometimes  used by S&P. It assumes  the  successful
completion of the project  being  financed by the debt being rated and indicates
that payment of debt service  requirements is largely or entirely dependent upon
the successful and timely completion of the project. This rating, however, while
addressing  credit  quality  subsequent to  completion of the project,  makes no
comment on the  likelihood  of, or the risk of default  upon  failure  of,  such
completion.

D.  BOND RATINGS

  Bond ratings are as follows:

  1. AAA -- Debt rated AAA has the highest rating assigned by S&P. Capacity to
pay interest and repay principal is extremely strong.

  2. AA -- Debt rated AA has a very strong  capacity to pay  interest  and repay
principal and differs from the higher rated issues only in small degree.

  3. A -- Debt rated A has a strong capacity to pay interest and repay principal
although it is somewhat more  susceptible  to the adverse  effects of changes in
circumstances and economic conditions than debt in higher rated categories.

  4. BBB -- Debt rated BBB is  regarded  as having an  adequate  capacity to pay
interest and repay principal.  Whereas it normally exhibits adequate  protection
parameters,  adverse  economic  conditions  or changing  circumstances  are more
likely to lead to a weakened  capacity to pay interest and repay  principal  for
debt in this category than in higher rated categories.

MOODY'S CORPORATE AND MUNICIPAL BOND RATINGS

A.  MUNICIPAL NOTES

  A Moody's  rating for  municipal  short-term  obligations  will be  designated
Moody's  Investment  Grade or ("MIG").  These ratings  recognize the  difference
between  short-term  credit  risk and  long-term  risk.  Factors  affecting  the
liquidity of the borrower and the short-term  cyclical  elements are critical in
short-term ratings.

  A  short-term  rating may also be assigned on issues with a demand  feature --
variable  rate demand  obligation  ("VRDO").  Such ratings will be designated as
VMIG.  Short-term  ratings on issues with demand features are  differentiated by
the use of the VMIG  symbol to reflect  such  characteristics  as  payment  upon
periodic  demand  rather than fixed  maturity  dates and payment  relying on the
external liquidity.

  The note ratings are as follows:

  1.  MIG1/VMIG1  This  designation  denotes the best quality.  There is present
strong  protection by  established  cash flows,  superior  liquidity  support or
demonstrated broadbased access to the market for refinancing.

  2. MIG2/VMIG2  This designation denotes high quality. Margins of protection
are ample although not so large as in the preceding group.

  3.  MIG3/VMIG3  This  designation  denotes  favorable  quality.  All  security
elements are accounted for but there is lacking the  undeniable  strength of the
preceding  grades.  Liquidity and cash flow  protection may be narrow and market
access for refinancing is likely to be less well established.

  4. MIG4/VMIG4 This designation  denotes adequate quality.  Protection commonly
regarded as  required of an  investment  security  is present and  although  not
distinctly or predominantly speculative, there is specific risk.

B.  CORPORATE AND MUNICIPAL BOND RATINGS

  1. Aaa -- Bonds rated Aaa are judged to be of the best quality. They carry the
smallest  degree of  investment  risk and are  generally  referred  to as "gilt-
edge." 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.

  2. Aa -- Bonds  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 the best  bonds  because  margins  of
protection may not be as large as in Aaa securities or fluctuation of protective
elements may be of greater amplitude or there may be other elements present that
make the long term risks appear somewhat larger than in Aaa securities.

  3. A -- Bonds 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 that
suggest a susceptibility to impairment sometime in the future.

  4. Baa -- Bonds rated Baa are considered to be 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 lacking or may be  characteristically  unreliable over any great
length of time. Such bonds lack outstanding  investment  characteristics  and in
fact have speculative characteristics as well.

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

  CON.  (--) --  Municipal  bonds  for  which  the  security  depends  upon  the
completion  of  some  act  or  the  fulfillment  of  some  condition  are  rated
conditionally.  These  are bonds  secured  by (1)  earnings  of  projects  under
construction,  (2) earnings of projects unseasoned in operation experience,  (3)
rentals that begin when facilities are completed,  or (4) payments to which some
other limiting condition attaches.  Parenthetical rating denotes probable credit
stature upon completion of construction or elimination of basis of condition.

  Those  municipal  bonds in the Aa, A, and Baa  groups  that  Moody's  believes
possess the strongest investment  attributes are designated by the symbols Aa 1,
A 1, and Baa 1.

FITCH CORPORATE AND MUNICIPAL RATINGS

A.  MUNICIPAL NOTES

  Fitch's  short-term  ratings  apply to debt  obligations  that are  payable on
demand or have  original  maturities  of  generally  three years or less.  These
include  commercial  paper,  certificates  of deposit,  medium-term  notes,  and
municipal and investment notes. The short-term rating places greater emphasis on
the  existence of liquidity  necessary  to meet the  issuer's  obligations  in a
timely manner.

  The note ratings are as follows:

  1. F-1+ Exceptionally  Strong Credit Quality.  Issues assigned this rating are
regarded as having the strongest degree of assurance for timely payment.

  2. F-1  Very Strong Credit Quality. Issues assigned this rating reflect an
assurance   of   timely   payment only slightly less in degree than issues rated
F-1+                              .

  3. F-2  Good Credit Quality. Issues assigned this rating have a satisfactory
degree of assurance for timely payment, but the margin of safety is not as
great as for issues assigned the two higher ratings.

  4. F-3 Fair Credit Quality.  Issues assigned this rating have  characteristics
suggesting that the degree of assurance for timely payment is adequate, however,
near-term  adverse  changes  could  cause  these  securities  to be rated  below
investment grade.

B.  CORPORATE AND MUNICIPAL BOND RATINGS

AAA --  Bonds  considered  to be  investment  grade  and of the  highest  credit
quality.  The obligor has an  exceptionally  strong  ability to pay interest and
repay  principal,  which is unlikely to be  affected by  reasonably  foreseeable
events.

AA -- Bonds  considered to be investment  grade and of very high credit quality.
The  obligor's  ability to pay  interest  and repay  principal  is very  strong,
although not quite as strong as bonds rated AAA.

A -- Bonds  considered to be investment  grade and of high credit  quality.  The
obligor's  ability to pay  interest  and repay  principal  is  considered  to be
strong, but may be more vulnerable to adverse changes in economic conditions and
circumstances than bonds with higher ratings.

BBB -- Bonds  considered  to be  investment  grade  and of  satisfactory  credit
quality. The obligor's ability to pay interest and repay principal is considered
to be  adequate.  Adverse  changes in  economic  conditions  and  circumstances,
however,  are more likely to have adverse  impact on these bonds,  and therefore
impair timely payment.  The likelihood that the ratings of these bonds will fall
below investment grade is higher than for bonds with higher ratings.

PLUS (+ ) OR MINUS  (-) signs are used  with a rating  symbol  to  indicate  the
relative position of a credit within the rating category.  Plus and minus signs,
however, are not used in the AAA category.

A CONDITIONAL  rating is premised on the  successful  completion of a project or
the occurrence of a specific event.

  Debt  rated  BB,  B,  CCC,  CC  and C by  S&P  is  regarded,  on  balance,  as
predominantly  speculative  with  respect to capacity to pay  interest and repay
principal in  accordance  with the terms of the  obligation.  BB  indicates  the
lowest degree of speculation and C the highest degree of speculation. While such
debt will likely have some  quality and  protective  characteristics,  these are
outweighed by large uncertainties or major risk exposures to adverse conditions.
Debt rated C1 by S&P is debt (income  bonds) on which no interest is being paid.
Debt rated D by S&P is in default and payment of interest  and/ or  repayment of
principal  is in  arrears.  Bonds  that are  rated  Caa by  Moody's  are of poor
standing.  Such  issues may be in default  or there may be present  elements  of
danger with respect to principal or interest. Bonds that are rated Ca by Moody's
represent  obligations  that are  speculative in a high degree.  Such issues are
often in default or have other  market  shortcomings.  Bonds that are rated C by
Moody's  are the lowest  rated  bonds,  and issues so rated can be  regarded  as
having extremely poor prospects of ever attaining any real investment  standing.
Debt  rated BB, B, CCC,  CC,  and C by Fitch is  regarded  as  speculative  with
respect to capacity to pay interest and repay  principal in accordance  with the
terms of the  obligation.  BB indicates the lowest degree of  speculation  and C
represents the highest degree of  speculation.  Debt rated DDD, DD, and D are in
default on interest and/or principal payments.

OBLIGATIONS OF FOREIGN BRANCHES OF UNITED STATES BANKS
  The obligations of foreign  branches of U.S. banks may be general  obligations
of the parent bank in addition to the issuing  branch,  or may be limited by the
terms of a specific obligation and by government regulation. Payment of interest
and principal upon these obligations may also be affected by governmental action
in the  country of domicile of the branch  (generally  referred to as  sovereign
risk).  In  addition,  evidences of  ownership  of such  securities  may be held
outside  the U.S.  and a Fund may be  subject to the risks  associated  with the
holding of such property overseas. Examples of governmental actions would be the
imposition  of  currency  controls,  interest  limitations,  withholding  taxes,
seizure of assets or the  declaration  of a  moratorium.  Various  provisions of
federal law  governing  domestic  branches  do not apply to foreign  branches of
domestic banks.

OBLIGATIONS OF UNITED STATES BRANCHES OF FOREIGN BANKS

  Obligations  of U.S.  branches of foreign banks may be general  obligations of
the parent  bank in addition  to the  issuing  branch,  or may be limited by the
terms of a specific obligation and by federal and state regulation as well as by
governmental  action  in the  country  in which  the  foreign  bank has its head
office. In addition,  there may be less publicly  available  information about a
U.S. branch of a foreign bank than about a domestic bank.

MASTER DEMAND NOTES

  Master demand notes are unsecured  obligations  that permit the  investment of
fluctuating  amounts by a Fund at varying  rates of interest  pursuant to direct
arrangements  between the Fund,  as lender,  and the issuer as borrower.  Master
demand  notes may  permit  daily  fluctuations  in the  interest  rate and daily
changes in the amounts  borrowed.  A Fund has the right to  increase  the amount
under the note at any time up to the full amount provided by the note agreement,
or to decrease  the amount.  The borrower may repay up to the full amount of the
note without  penalty.  Notes acquired by a Fund permit a Fund to demand payment
of  principal  and  accrued  interest  at any time (on not more than seven days'
notice).  Notes  acquired by a Fund may have  maturities  of more than one year,
provided  that (1) the Fund is  entitled  to payment of  principal  and  accrued
interest  upon not more than seven days notice,  and (2) the rate of interest on
such notes is adjusted  automatically at periodic  intervals which normally will
not exceed 31 days,  but may extend up to one year.  The notes will be deemed to
have a maturity equal to the longer of the period remaining to the next interest
rate  adjustment or the demand notice  period.  Because these types of notes are
direct lending  arrangements  between the lender and borrower,  such instruments
are not  normally  traded  and there is no  secondary  market  for these  notes,
although they are  redeemable  and thus  repayable by the borrower at face value
plus  accrued  interest at any time.  Accordingly,  a Fund's  right to redeem is
dependent  on the  ability of the  borrower  to pay  principal  and  interest on
demand. In connection with master demand note arrangements,  Keystone considers,
under standards  established by the Board of Trustees,  earning power, cash flow
and other  liquidity  ratios of the borrower and will monitor the ability of the
borrower to pay principal and interest on demand.  These notes are not typically
rated by credit rating agencies. Unless rated, a Fund may invest in them only if
at the time of an  investment  the issuer  meets the  criteria  established  for
commercial paper discussed in the statement of additional information.

REPURCHASE AGREEMENTS

  A Fund may enter into  repurchase  agreements with member banks of the Federal
Reserve  System  having at least $1 billion in assets,  primary  dealers in U.S.
government securities or other financial institutions believed by Keystone to be
creditworthy.  Such persons must be  registered  as U.S.  government  securities
dealers with appropriate regulatory  organizations.  Under such agreements,  the
bank,  primary dealer or other financial  institution  agrees upon entering into
the  contract to  repurchase  the  security  at a mutually  agreed upon date and
price,  thereby  determining  the yield during the term of the  agreement.  This
results in a fixed rate of return insulated from market fluctuations during such
period. Under a repurchase agreement,  the seller must maintain the value of the
securities  subject to the agreement at not less than the repurchase price, such
value being determined on a daily basis by marking the underlying  securities to
their market value.  Although the securities subject to the repurchase agreement
might bear  maturities  exceeding  a year,  the Funds only  intend to enter into
repurchase  agreements  that  provide for  settlement  within a year and usually
within seven days.  Securities subject to repurchase  agreements will be held by
the FUND's  custodian or in the Federal Reserve book entry system.  The Funds do
not bear the risk of a decline in the value of the  underlying  security  unless
the  seller  defaults  under  its  repurchase  obligation.  In  the  event  of a
bankruptcy or other default of a seller of a repurchase agreement,  a Fund could
experience  both delays in  liquidating  the  underlying  securities and losses,
including (1) possible declines in the value of the underlying securities during
the period  while the Fund seeks to enforce  its rights  thereto;  (2)  possible
subnormal levels of income and lack of access to income during this period;  and
(3) expenses of  enforcing  its rights.  The Board of Trustees  has  established
procedures  to evaluate the  creditworthiness  of each party with whom each Fund
enters into repurchase  agreements by setting guidelines and standards of review
for  Keystone  and  monitoring  Keystone's  actions  with  regard to  repurchase
agreements.

REVERSE REPURCHASE AGREEMENTS

  Under a reverse repurchase  agreement,  a Fund would sell securities and agree
to repurchase them at a mutually  agreed upon date and price.  Each Fund intends
to enter into reverse  repurchase  agreements to avoid otherwise  having to sell
securities during unfavorable market conditions in order to meet redemptions. At
the time a Fund enters into a reverse repurchase agreement,  it will establish a
segregated  account with the FUND's custodian  containing  liquid assets such as
U.S.  government  securities or other high grade debt securities  having a value
not  less  than the  repurchase  price  (including  accrued  interest)  and will
subsequently  monitor the account to ensure  such value is  maintained.  Reverse
repurchase  agreements  involve the risk that the market value of the securities
that a Fund is obligated to repurchase may decline below the  repurchase  price.
Borrowing and reverse  repurchase  agreements  magnify the potential for gain or
loss  on  the  portfolio  securities  of a Fund  and,  therefore,  increase  the
possibility  of  fluctuation  in the Fund's net asset value.  Such practices may
constitute  leveraging.  In the event the  buyer of  securities  under a reverse
repurchase  agreement files for bankruptcy or becomes  insolvent,  such buyer or
its trustee or receiver may receive an extension of time to determine whether to
enforce a Fund's  obligation to repurchase  the securities and the Fund's use of
the proceeds of the reverse  repurchase  agreement may effectively be restricted
pending such determination.  The staff of the Securities and Exchange Commission
("SEC")  has taken the  position  that the 1940 Act  treats  reverse  repurchase
agreements as being included in the percentage limit on borrowings  imposed on a
fund.

"WHEN ISSUED" SECURITIES

  Each Fund may also  purchase  and sell  securities  and  currencies  on a when
issued and delayed delivery basis. When issued or delayed delivery  transactions
arise when securities or currencies are purchased or sold by a Fund with payment
and delivery taking place in the future in order to secure what is considered to
be an advantageous  price and yield to the Fund at the time of entering into the
transaction.   When  a  Fund  engages  in  when  issued  and  delayed   delivery
transactions,  the Fund  relies on the buyer or  seller,  as the case may be, to
consummate  the  sale.  Failure  to do so  may  result  in a  Fund  missing  the
opportunity  to  obtain a price or yield  considered  to be  advantageous.  When
issued and  delayed  delivery  transactions  may be expected to occur a month or
more before delivery is due.  However,  no payment or delivery is made by a Fund
until it receives payment or delivery from the other party to the transaction. A
separate  account  of  liquid  assets  equal  to  the  value  of  such  purchase
commitments  will be maintained  until payment is made.  When issued and delayed
delivery  agreements  are  subject  to risks from  changes  in value  based upon
changes in the level of interest rates, currency rates and other market factors,
both  before  and after  delivery.  A Fund does not  accrue  any  income on such
securities  or  currencies  prior to their  delivery.  To the  extent  each Fund
engages  in  when  issued  and  delayed  delivery  transactions,  it  will do so
consistent with its investment objective and policies and not for the purpose of
investment leverage.

LOANS OF SECURITIES TO BROKER-DEALERS

  Each Fund may lend  securities  to brokers and dealers  pursuant to agreements
requiring  that the loans be  continuously  secured by cash or securities of the
U.S. government,  its agencies or instrumentalities,  or any combination of cash
and such  securities,  as collateral equal at all times in value to at least the
market value of the securities  loaned.  Such securities  loans will not be made
with  respect  to a  Fund  if as a  result  the  aggregate  of  all  outstanding
securities  loans  exceeds 15% of the value of the Fund's  total assets taken at
their current value.  A Fund  continues to receive  interest or dividends on the
securities  loaned and  simultaneously  earns  interest on the investment of the
cash loan  collateral in U.S.  Treasury notes,  certificates  of deposit,  other
high-grade,   short-term  obligations  or  interest  bearing  cash  equivalents.
Although voting rights attendant to securities loaned pass to the borrower, such
loans may be called at any time and will be called so that the securities may be
voted by a Fund if, in the opinion of the Fund, a material  event  affecting the
investment  is to  occur.  There may be risks of delay in  receiving  additional
collateral or in recovering the securities  loaned or even loss of rights in the
collateral  should the borrower of the securities  fail  financially.  Loans may
only  be made to  borrowers  deemed  to be of  good  standing,  under  standards
approved  by the Board of  Trustees,  when the income to be earned from the loan
justifies the attendant risks.

DERIVATIVES

  Each Fund may use  derivatives in  furtherance  of its  investment  objective.
Derivatives are financial  contracts whose value depends on, or is derived from,
the value of an underlying asset,  reference rate or index. These assets, rates,
and indices may include bonds, stocks, mortgages,  commodities,  interest rates,
currency exchange rates, bond indices and stock indices. Derivatives can be used
to earn income or protect  against  risk, or both.  For example,  one party with
unwanted  risk may agree to pass that risk to  another  party who is  willing to
accept the risk, the second party being  motivated,  for example,  by the desire
either to earn income in the form of a fee or premium from the first  party,  or
to reduce its own unwanted  risk by  attempting to pass all or part of that risk
to the first party.

  Derivatives  can be used by  investors  such as the Funds to earn  income  and
enhance  returns,  to hedge or adjust  the risk  profile of the  portfolio,  and
either in place of more traditional  direct investments or to obtain exposure to
otherwise  inaccessible  markets.  Each Fund is permitted to use derivatives for
one or more of these  purposes.  Each of these uses entails greater risk than if
derivatives  were used  solely  for  hedging  purposes.  The  Funds use  futures
contracts and related options for hedging  purposes.  Derivatives are a valuable
tool which,  when used  properly,  can provide  significant  benefit to a Fund's
shareholders.  Keystone is not an aggressive user of derivatives with respect to
the Funds.  However,  a Fund may take  positions in those  derivatives  that are
within its investment policies if, in Keystone's  judgement,  this represents an
effective response to current or anticipated  market conditions.  Keystone's use
of  derivatives  is subject to continuous  risk  assessment and control from the
standpoint of a Fund's investment objectives and policies.

  Derivatives  may  be  (1)  standardized,   exchange-traded  contracts  or  (2)
customized,  privately negotiated contracts. Exchange-traded derivatives tend to
be more liquid and  subject to less  credit risk than  those that are  privately
negotiated.

  There are four principal types of derivative instruments -- options,  futures,
forwards and swaps -- from which  virtually any type of  derivative  transaction
can be created.  Further information  regarding options and futures, is provided
later in this  section  and is provided in the FUND's  statement  of  additional
information.

  Debt instruments that incorporate one or more of these building blocks for the
purpose of determining the principal  amount of and/or rate of interest  payable
on the debt  instruments  are often referred to as "structured  securities."  An
example of this type of structured  security is indexed  commercial  paper.  The
term is also used to describe certain  securities  issued in connection with the
restructuring of certain foreign obligations. See "Structured Securities" below.
The term  "derivative" is also sometimes used to describe  securities  involving
rights to a portion of the cash flows from an  underlying  pool of  mortgages or
other  assets from which  payments  are passed  through to the owner of, or that
collateralize, the securities.

  While the judicious use of derivatives by experienced investment managers such
as Keystone can be beneficial,  derivatives  also involve risks  different from,
and, in certain  cases,  greater than, the risks  presented by more  traditional
investments.  Following is a general  discussion  of important  risk factors and
issues concerning the use of derivatives that investors should understand before
investing in a Fund.

* Market Risk -- This is the general risk attendant to all investments  that the
  value of a particular  investment  will  decline or otherwise  change in a way
  detrimental to a Fund's interest.

* Management Risk -- Derivative products are highly specialized instruments that
  require   investment   techniques  and  risk  analyses  different  from  those
  associated  with  stocks  and  bonds.  The  use of a  derivative  requires  an
  understanding  not  only  of  the  underlying  instrument,  but  also  of  the
  derivative  itself,  without the benefit of observing the  performance  of the
  derivative under all possible market  conditions.  In particular,  the use and
  complexity of  derivatives  require the  maintenance  of adequate  controls to
  monitor the  transactions  entered into, the ability to assess the risk that a
  derivative  adds to a Fund's  portfolio  and the  ability to  forecast  price,
  interest rate or currency exchange rate movements correctly.

* Credit  Risk -- This is the risk that a loss may be  sustained  by a Fund as a
  result of the failure of another party to a derivative (usually referred to as
  a  "counterparty")  to comply with the terms of the derivative  contract.  The
  credit  risk for  exchange  traded  derivatives  is  generally  less  than for
  privately  negotiated  derivatives,  since the  clearing  house,  which is the
  issuer  or  counterparty  to  each  exchange-traded  derivative,   provides  a
  guarantee of  performance.  This  guarantee  is  supported by a daily  payment
  system (i.e., margin requirements)  operated by the clearing house in order to
  reduce overall credit risk. For privately negotiated derivatives,  there is no
  similar   clearing  agency   guarantee.   Therefore,   a  Fund  considers  the
  creditworthiness of each counterparty to a privately negotiated  derivative in
  evaluating potential credit risk.

* Liquidity  Risk --  Liquidity  risk exists  when a  particular  instrument  is
  difficult to purchase or sell.  If a derivative  transaction  is  particularly
  large  or if the  relevant  market  is  illiquid  (as is the  case  with  many
  privately  negotiated  derivatives),  it may not be  possible  to  initiate  a
  transaction or liquidate a position at an advantageous price.

* Leverage Risk -- Since many  derivatives  have a leverage  component,  adverse
  changes  in the  value or level of the  underlying  asset,  rate or index  can
  result  in a loss  substantially  greater  than  the  amount  invested  in the
  derivative itself. In the case of swaps, the risk of loss generally is related
  to a notional principal amount,  even if the parties have not made any initial
  investment.  Certain  derivatives  have  the  potential  for  unlimited  loss,
  regardless of the size of the initial investment.

* Other Risks -- Other risks in using derivatives include the risk of mispricing
  or improper valuation and the inability of derivatives to correlate  perfectly
  with underlying  assets,  rates and indices.  Many derivatives,  in particular
  privately negotiated  derivatives,  are complex and often valued subjectively.
  Improper  valuations  can result in  increased  cash payment  requirements  to
  counterparties  or a loss  of  value  to a  Fund.  Derivatives  do not  always
  perfectly or even highly correlate or track the value of the assets,  rates or
  indices  they are  designed to closely  track.  Consequently,  a Fund's use of
  derivatives  may not always be an effective  means of, and sometimes  could be
  counterproductive to, furthering the Fund's investment objective.

OPTIONS TRANSACTIONS

  WRITING COVERED OPTIONS.  The Fund may write (i.e., sell) covered call and put
options. By writing a call option, the Fund becomes obligated during the term of
the option to deliver the  securities  underlying the option upon payment of the
exercise price.  By writing a put option,  a Fund becomes  obligated  during the
term of the  option to  purchase  the  securities  underlying  the option at the
exercise  price if the option is  exercised.  The Fund also may write  straddles
(combinations of covered puts and calls on the same underlying security).

  Each Fund may only write "covered" options.  This means that so long as a Fund
is  obligated  as the  writer  of a call  option,  it will  own  the  underlying
securities  subject  to the  option  or,  in the  case of call  options  on U.S.
Treasury bills, the Fund might own substantially similar U.S. Treasury bills. If
a Fund has written options against all of its securities which are available for
writing options,  the Fund may be unable to write  additional  options unless it
sells a portion of its portfolio holdings to obtain new securities against which
it can write  options.  If this were to occur,  higher  portfolio  turnover  and
correspondingly  greater  brokerage  commissions and other transaction costs may
result. However, the Funds do not expect that this will occur.

  Each Fund will be considered  "covered" with respect to a put option it writes
if, so long as it is obligated as the writer of the put option,  it deposits and
maintains  with its  custodian in a segregated  account  liquid  assets having a
value equal to or greater than the exercise price of the option.

  The principal  reason for writing call or put options is to obtain,  through a
receipt of  premiums,  a greater  current  return  than would be realized on the
underlying  securities  alone.  A Fund receives a premium from writing a call or
put option, which it retains whether or not the option is exercised.  By writing
a call  option,  a Fund  might  lose the  potential  for gain on the  underlying
security  while the  option is open,  and by writing a put option the Fund might
become  obligated to purchase the underlying  security for more than its current
market price upon exercise.

  PURCHASING OPTIONS.  Each Fund may purchase put or call options, including
purchasing put or call options for the purpose of offsetting previously
written put or call options of the same series.

  If a Fund is unable to effect a closing  purchase  transaction with respect to
covered options it has written, the Fund will not be able to sell the underlying
security or dispose of assets  held in a  segregated  account  until the options
expire or are exercised.

  An option position may be closed out only in a secondary  market for an option
of the same series.  Although a Fund generally will write only those options for
which there appears to be an active secondary market, there is no assurance that
a liquid secondary market will exist for any particular option at any particular
time,  and for some options no  secondary  market may exist.  In such event,  it
might not be possible to effect a closing transaction in a particular option.

  Options on some securities are relatively new, and it is impossible to predict
the amount of trading interest that will exist in such options.  There can be no
assurance  that viable  markets will  develop or  continue.  The failure of such
markets to develop or continue  could  significantly  impair a Fund's ability to
use such options to achieve its investment objective.

  OPTIONS TRADING  MARKETS.  Options in which each Fund will trade generally are
listed  on  national  securities  exchanges.  Exchanges  on which  such  options
currently  are traded  include the Chicago  Board  Options  Exchange and the New
York,  American,  Pacific  and  Philadelphia  Stock  Exchanges.  Options on some
securities may not be listed on any Exchange, but traded in the over-the-counter
market.  Options  traded in the  over-the-counter  market involve the additional
risk that securities  dealers  participating in such transactions  could fail to
meet  their   obligations   to  a  Fund.  The  use  of  options  traded  in  the
over-the-counter  market may be subject to limitations  imposed by certain state
securities  authorities.  In  addition  to  the  limits  on its  use of  options
discussed herein, each Fund is subject to the investment  restrictions described
in this prospectus and in the statement of additional information.

  The staff of the SEC is of the view that the premiums that a Fund pays for the
purchase of unlisted options, and the value of securities used to cover unlisted
options written by a Fund, are considered to be invested in illiquid  securities
or assets for the purpose of calculating  whether the Fund is in compliance with
its investment restriction relating to illiquid investments.

FUTURES TRANSACTIONS

  Each Fund may enter into currency and other  financial  futures  contracts and
write options on such contracts.  Each Fund intends to enter into such contracts
and related options for hedging  purposes.  Each Fund will enter into futures on
securities  or  currencies or  index-based  futures  contracts in order to hedge
against  changes in interest or exchange rates or securities  prices.  A futures
contract on securities  or currencies is an agreement to buy or sell  securities
or currencies at a specified price during a designated month. A futures contract
on a securities  index does not involve the actual  delivery of securities,  but
merely  requires  the  payment  of a cash  settlement  based on  changes  in the
securities  index.  A Fund does not make  payment  or  deliver  securities  upon
entering into a futures contract.  Instead, it puts down a margin deposit, which
is adjusted to reflect  changes in the value of the contract and which continues
until the contract is terminated.

  Each Fund may sell or purchase futures  contracts.  When a futures contract is
sold by a Fund,  the value of the  contract  will tend to rise when the value of
the underlying  securities or currencies  declines and to fall when the value of
such securities or currencies increases. Thus, each Fund sells futures contracts
in order  to  offset a  possible  decline  in the  value  of its  securities  or
currencies.  If a futures  contract  is  purchased  by a Fund,  the value of the
contract  will  tend to rise  when the  value of the  underlying  securities  or
currencies increases and to fall when the value of such securities or currencies
declines.  Each Fund intends to purchase futures contracts in order to establish
what is believed  by  Keystone  to be a  favorable  price and rate of return for
securities  or  favorable  exchange  rate for  currencies  the Fund  intends  to
purchase.

  Each Fund also intends to purchase  put and call options on futures  contracts
for hedging  purposes.  A put option purchased by a Fund would give it the right
to  assume a  position  as the  seller  of a  futures  contract.  A call  option
purchased  by a Fund  would  give it the  right  to  assume  a  position  as the
purchaser of a futures contract. The purchase of an option on a futures contract
requires a Fund to pay a premium.  In exchange for the  premium,  a Fund becomes
entitled to exercise the benefits, if any, provided by the futures contract, but
is not required to take any action under the  contract.  If the option cannot be
exercised  profitably  before it  expires,  a Fund's loss will be limited to the
amount of the premium and any transaction costs.

  Each Fund may enter into closing  purchase and sale  transactions  in order to
terminate a futures  contract  and may sell put and call options for the purpose
of closing out its options  positions.  A Fund's  ability to enter into  closing
transactions  depends on the development  and maintenance of a liquid  secondary
market.  There is no assurance that a liquid secondary market will exist for any
particular  contract or at any  particular  time.  As a result,  there can be no
assurance that a Fund will be able to enter into an offsetting  transaction with
respect to a particular  contract at a particular time. If a Fund is not able to
enter into an offsetting  transaction,  the Fund will continue to be required to
maintain  the margin  deposits  on the  contract  and to complete  the  contract
according to its terms,  in which case it would  continue to bear market risk on
the transaction.

  Although  futures and options  transactions  are  intended to enable a Fund to
manage  market,  interest rate or exchange rate risk,  unanticipated  changes in
interest  rates,  exchange  rates  or  market  prices  could  result  in  poorer
performance than if it had not entered into these transactions. Even if Keystone
correctly  predicts  interest  or  exchange  rate  movements,  a hedge  could be
unsuccessful  if  changes  in the  value of a Fund's  futures  position  did not
correspond to changes in the value of its investments.  This lack of correlation
between a Fund's futures and securities or currencies positions may be caused by
differences  between the  futures and  securities  or  currencies  markets or by
differences  between the  securities or currencies  underlying a Fund's  futures
position and the securities or currencies held by or to be purchased for a Fund.
Keystone  will attempt to minimize  these risks  through  careful  selection and
monitoring of the Fund's futures and options positions.

  The  Funds do not  intend  to use  futures  transactions  for  speculation  or
leverage.  Each Fund has the ability to write options on futures,  but currently
intends to write such options only to close out options purchased by a Fund. The
Funds will not change these policies  without  supplementing  the information in
the FUND's prospectus and statement of additional information.

FOREIGN CURRENCY TRANSACTIONS

  As discussed  above,  if permitted by its investment  policies,  each Fund may
invest  in  securities  of  foreign  issuers.  When a Fund  invests  in  foreign
securities they usually will be denominated in foreign currencies,  and the Fund
temporarily may hold funds in foreign currencies. Thus, the value of Fund shares
will be affected by changes in exchange rates.

  As one way of managing  exchange  rate risk,  in  addition  to  entering  into
currency  futures  contracts,  a Fund may enter into forward  currency  exchange
contracts  (agreements to purchase or sell  currencies at a specified  price and
date). The exchange rate for the transaction (the amount of currency a Fund will
deliver or receive when the contract is  completed)  is fixed when a Fund enters
into the contract.  A Fund usually will enter into these  contracts to stabilize
the U.S.  dollar  value of a security  it has  agreed to buy or sell.  Each Fund
intends to use these  contracts to hedge the U.S.  dollar value of a security it
already  owns,  particularly  if a Fund  expects a decrease  in the value of the
currency in which the  foreign  security  is  denominated.  Although a Fund will
attempt to benefit  from using  forward  contracts,  the  success of its hedging
strategy  will depend on  Keystone's  ability to predict  accurately  the future
exchange rates between foreign  currencies and the U.S.  dollar.  The value of a
Fund's investments denominated in foreign currencies will depend on the relative
strength of those  currencies  and the U.S.  dollar,  and a Fund may be affected
favorably or unfavorably  by changes in the exchange  rates or exchange  control
regulations  between  foreign  currencies  and the  dollar.  Changes  in foreign
currency  exchange  rates also may affect the value of  dividends  and  interest
earned,  gains and losses  realized on the sale of securities and net investment
income and gains, if any, to be distributed to shareholders by a Fund. Each Fund
may also purchase and sell options  related to foreign  currencies in connection
with hedging strategies.

VARIABLE AND FLOATING RATE INSTRUMENTS.  Fixed-income securities may have fixed,
variable or floating  rates of interest.  Variable and floating rate  securities
pay interest at rates that are adjusted  periodically,  according to a specified
formula.  A "variable"  interest rate adjusts at predetermined  intervals (e.g.,
daily,  weekly or monthly),  while a "floating" interest rate adjusts whenever a
specified benchmark rate (such as the bank prime lending rate) changes.

  If permitted by its  investment  policies,  a Fund may invest in  fixed-income
securities  that pay  interest  at a coupon  rate  equal  to a base  rate,  plus
additional  interest for a certain  period of time if short-term  interest rates
rise above a  predetermined  level or "cap."  The  amount of such an  additional
interest  payment  typically is calculated under a formula based on a short-term
interest rate index multiplied by a designated factor.

INVERSE FLOATING RATE  SECURITIES.  If permitted by its investment  policies,  a
Fund may also  invest in  securities  with rates that move  inversely  to market
rates  ("inverse  floaters").  An inverse  floater  bears an interest  rate that
resets in the  opposite  direction  of the change in a specified  interest  rate
index.  As market  interest rates rise, the interest rate on the inverse floater
goes down,  and vice  versa.  Inverse  floaters  tend to exhibit  greater  price
volatility than  fixed-rate  bonds of similar  maturity and credit quality.  The
interest rates on inverse floaters may be significantly  reduced,  even to zero,
if interest rates rise. Moreover,  the secondary market for inverse floaters may
be limited in rising interest rate environments.

  An inverse  floater may be  considered  to be leveraged to the extent that its
interest rate varies by a magnitude  that exceeds the magnitude of the change in
the index rate of interest.  The higher  degree of leverage  inherent in inverse
floaters is associated with greater volatility in market value.

STRUCTURED  SECURITIES.  Structured  securities generally represent interests in
entities  organized  and operated  solely for the purpose of  restructuring  the
investment  characteristics  of debt  obligations.  This  type of  restructuring
involves the deposit  with or purchase by an entity,  such as a  corporation  or
trust, of specified instruments (such as commercial bank loans) and the issuance
by that entity of one or more  classes of  structured  securities  backed by, or
representing  interests  in, the  underlying  instruments.  The cash flow on the
underlying  instruments  may be  apportioned  among the newly issued  structured
securities to create securities with different  investment  characteristics such
as varying maturities,  payment priorities and interest rate provisions, and the
extent of the payments made with respect to  structured  securities is dependent
on the extent of the cash flow on the underlying instruments. Because structured
securities typically involve no credit enhancement,  their credit risk generally
will be equivalent to that of the underlying instruments.  Structured securities
of a given class may be either  subordinated or  unsubordinated  to the right of
payment of another  class.  Subordinated  structured  securities  typically have
higher  yields  and  present  greater  risks  than   unsubordinated   structured
securities.

                        KEYSTONE FLORIDA TAX FREE FUND
DESCRIPTION OF STATE AND LOCAL TAX TREATMENT
  Florida  does not  presently  impose an  income  tax on  individuals  and thus
individual  shareholders  of the Florida Fund will not be subject to any Florida
state income tax on distributions  received from the Florida Fund. Shares of the
Florida Fund may, however,  be subject to Florida  intangible  personal property
tax  imposed on  certain  property  held on  January 1 of each  year.  Corporate
shareholders,  depending on the domicile of the  corporation,  may be subject to
Florida  corporate  income taxes  depending on the portion of the Florida Fund's
income that is allocable to Florida under applicable Florida law.

  According  to a  technical  assistance  advisement  from the State of Florida,
Department  of Revenue,  shares of the Florida Fund owned by a Florida  resident
will  be  exempt  from  the  intangible  personal  property  tax so  long as its
portfolio  assets consist 100% of securities that are exempt from the intangible
personal property tax,  including Florida municipal bonds and/or municipal bonds
issued by the U.S.  Government or the  governments  of Puerto Rico or Guam.  The
technical assistance advisement will not be binding on the Department of Revenue
for any  shareholder  of the Fund;  however,  such  advisements  are  considered
helpful in understanding the Department's position on any particular tax issue.

SPECIAL FACTORS AFFECTING THE FLORIDA FUND

  Under  current  law,  the State of Florida is  required to maintain a balanced
budget so that current expenses are met from current revenues.  Florida does not
currently  impose a tax on personal  income.  It does impose a tax on  corporate
income derived from activities within the State. In addition, Florida imposes an
ad valorem tax on certain  intangible  property (see above) as well as sales and
use taxes. These taxes are the principal source of funds to meet State expenses,
including  repayment of, and interest on,  obligations backed solely by the full
faith and credit of the State.

  Florida's  Constitution permits the issuance of state or municipal obligations
pledging the full faith and credit of the State,  with a concurring  vote by the
respective electors,  to finance or refinance capital projects authorized by the
Legislature.  The State  Constitution  also provides that the Legislature  shall
appropriate  monies  sufficient to pay debt service on state bonds  pledging the
full faith and credit of the State as they become due.  All State tax  revenues,
other than trust funds dedicated by the State  Constitution  for other purposes,
are available for such an appropriation, if required.

  On the other hand,  municipalities  and other  political  subdivisions  of the
State  principally  rely on a combination  of ad valorem taxes on real property,
user  fees and  occupational  license  fees to meet  their  day-to-day  expenses
including  the  repayment  of principal  of, and interest on, their  obligations
backed by their full faith and credit.  (Revenue bonds, of course, are dependent
on the revenue generated by a specific facility or enterprise.)

  Florida  has  experienced  substantial  population  increases  as a result  of
migration to Florida  from other areas of the U.S.  and from foreign  countries.
This  population  growth is expected to  continue,  and it is  anticipated  that
corresponding  increases in State  revenues  will be  necessary  during the next
decade to meet  increased  burdens on the  various  public  and social  services
provided by the State.

  Florida's  ability to meet increasing  expenses will be dependent in part upon
the State's  continued  ability to foster business and economic growth.  Florida
has experienced  significant  increases in the  technology-based and other light
industries and in the service  sector.  This growth has  diversified the State's
overall  economy,  which at one time was  dominated  by the citrus  and  tourism
industries.  The State's  economic  and  business  growth  could be  restricted,
however, by the natural limitations on Florida's water supplies.

                     KEYSTONE MASSACHUSETTS TAX FREE FUND
DESCRIPTION OF STATE AND LOCAL TAX TREATMENT
  Under Massachusetts law, individual shareholders of the Massachusetts Fund who
are  subject  to  Massachusetts  personal  income  tax  will not be  subject  to
Massachusetts personal income tax on dividends paid by the Massachusetts Fund to
the extent such  dividends  are exempt from  federal  income tax and are derived
from interest payments on Massachusetts municipal securities.  Long term capital
gains  distributions  are taxable as long term capital  gains,  except that such
distributions  derived from the sale of certain  Massachusetts  obligations  are
exempt from Massachusetts personal income tax. These obligations,  which are few
in number,  are those issued pursuant to legislation that  specifically  exempts
gain on their  sale from  Massachusetts  income  taxation.  Dividends  and other
distributions are not exempt from Massachusetts corporate excise tax.

SPECIAL FACTORS AFFECTING THE MASSACHUSETTS FUND

  During the past decade, the Massachusetts economy shifted from labor intensive
manufacturing to services,  especially in the medical and  biotechnology  areas.
Although The Commonwealth experienced an economic slowdown during the recession,
especially in high  technology,  real estate,  banking,  and defense,  there are
signs of improvement. While roughly 9.5% of the employment base was lost between
1989 and 1991, employment rose 0.4% between November,  1992 and November,  1993.
Although job losses continued in high tech manufacturing and finance during 1992
and 1993,  strong gains were registered in services,  construction and high tech
non-manufacturing.  The December,  1993  unemployment  rate was 6.3% compared to
6.4% for the nation.  In addition,  per capita  personal income averaged 118% of
the national average in 1992.

  Although The  Commonwealth  experienced  quite a slowdown during the recession
with  spending  exceeding  revenues,  beginning  in 1991  the  Commonwealth  has
experienced a turn-around  in its finances  with  revenues  exceeding  spending.
Budgeted  expenditures for fiscal 1989, 1990 and 1991 were approximately $12.643
billion,  $13.260  billion  and $13.659  billion,  respectively  while  budgeted
revenues and other sources for those years were  approximately  $11.970 billion,
$12.008  billion and $13.634  billion,  respectively.  By  comparison,  budgeted
revenues and other sources  increased by approximately  0.7% from fiscal 1991 to
fiscal 1992, while tax revenues increased by 5.4% for the same period.  Budgeted
expenditures   in  fiscal  1992  were  1.7%  lower  than  fiscal  1991  budgeted
expenditures.  Furthermore,  total  revenues  and other  sources for fiscal 1993
increased  approximately  6.9% from fiscal 1992, while tax revenues increased by
4.7% for the same period.  Budgeted  expenditures  and other uses in fiscal 1993
were  approximately  9.6% higher than fiscal 1992  expenditures  and other uses.
Fiscal 1993 ended with  positive fund  balances of $562.5  million,  including a
combined balance of $452.1 million in the stabilization and undesignated general
funds.  By  comparison,  The  Commonwealth  ended the 1989 fiscal year with fund
balances in deficit by $319.3 million.

  The fiscal 1994  budget,  as signed into law by the Governor on July 19, 1993,
provides for expenditures of approximately  $15.500 billion, an increase of 5.5%
over fiscal 1993 levels.  Budgeted  revenues for fiscal 1994 are estimated to be
approximately   $15.483   billion,   which  is  5.3%  higher  than  fiscal  1993
expenditures.  This amount  includes  estimated  tax  revenues of  approximately
$10.560 billion,  which is 6.3% higher than fiscal 1993 tax revenues. For fiscal
1994, a combined balance of $541.4 million is expected in the  stabilization and
undesignated  general  funds.  The fiscal  1994  budget is based  upon  numerous
spending and revenue estimates, the achievement of which cannot be assured.

  In June 1993, new comprehensive  education reform legislation was enacted.  It
is expected that this  legislation will require annual increases in expenditures
for education  purposes  above fiscal 1993 base spending of $1.289  billion,  of
approximately  $175 million in fiscal 1994, $141 million in fiscal 1995 and $662
million  in fiscal  1996.  The  fiscal  1994  budget  includes  $175  million in
appropriations to satisfy this legislation.

  In November 1980, voters in The Commonwealth  approved a state-wide limitation
initiative  petition,  commonly  known as  Proposition  2 1/2, to constrain  the
levels of property  taxation and to limit the charges and fees imposed on cities
and towns by certain governmental  entities.  Many communities have responded to
the limitations of Proposition 2 1/2 through statutorily permitted overrides and
exclusions.  Override activity peaked in fiscal 1991 when 100 of 182 communities
had successful votes,  adding $58.5 million to their levy limits.  During fiscal
years 1992 and 1993,  123  communities  had  successful  votes  totalling  $47.4
million.  Although  Proposition 2 1/2 will continue to constrain  local property
tax revenues, significant capacity exists for overrides in nearly all cities and
towns.

  An  expanded   discussion   is  contained  in  the   statement  of  additional
information.

                   KEYSTONE NEW YORK INSURED TAX FREE FUND
DESCRIPTION OF STATE AND LOCAL TAX TREATMENT
  Individual  shareholders  of the New York  Insured Fund who are subject to New
York State and New York City personal income tax will not be subject to New York
State or City personal income tax on dividends paid by the New York Insured Fund
to the extent that they are derived from interest on obligations of the State of
New York and its political  subdivisions that is exempt from federal income tax.
In addition,  dividends  derived  from  interest on debt  obligations  issued by
certain other governmental entities (for example, U.S.
territories) will be similarly exempt.

  For New York State and City personal  income tax  purposes,  long term capital
gain  distributions  are taxable as long term capital  gains  regardless  of the
length of time  shareholders  have owned their shares.  Short term capital gains
and any other taxable income are taxable as ordinary income.

  To the extent that investors are obligated to pay state or local taxes outside
of the State of New York,  dividends  earned  by an  investment  in the New York
Insured Fund may represent taxable income.  Distributions from investment income
and capital gains, including  exempt-interest  dividends,  may be subject to New
York State franchise taxes and to the New York City General  Corporation Tax, if
received by a corporation subject to those taxes, to state taxes in states other
than New York and to local taxes in cities other than New York City.

SPECIAL FACTORS AFFECTING THE NEW YORK FUND

  The New York economy was severely impacted by the recession,  but it has begun
to show signs of recovery.  The  recession has been more severe in New York than
in  other  parts  of the  nation,  owing to a  significant  retrenchment  in the
financial services industry, cutbacks in defense spending, and an overbuilt real
estate  market.   More  than  564,000  jobs  were  lost  during  the  recession,
representing 7% of the pre-recession base. During 1993,  employment continued to
decline but at  diminishing  rates (a 0.3% decline  during  1993),  indicating a
stabilizing  economy.  A modest job growth of approximately  0.8% is anticipated
for 1994. It is  anticipated  that New York's  service and trade sectors will be
the  major  contributors  to this  growth,  while  the  manufacturing  sector is
expected to continue to contract.  The State's economy is significantly affected
by New York City's economy by virtue of New York City's  dominance in population
and  economic  activity.  New York City  accounts for  approximately  41% of the
State's population and personal income.

  The revised 1993-1994 State Financial Plan is based on an economic  projection
that New  York  will  perform  more  poorly  than the  nation  as a whole.  Many
uncertainties  exist in  forecasts of the State's  economy,  which could have an
adverse  effect  on the  State,  and there  can be no  assurance  that the State
economy  will not  experience  worse-than-predicted  results in the 1994  fiscal
year, with corresponding material and adverse effects on the State's projections
of receipts and disbursements.

  For fiscal 1993, State financial operations produced a $671 million surplus on
a general fund budget of nearly $31 billion. This surplus followed four years of
operating deficits. On a GAAP basis, the accumulated general fund deficit peaked
in 1991 at $6.2 billion and then decreased to $2.6 billion for fiscal 1993. Debt
reform is the principal  cause for this  improvement.  Short- term  borrowing is
only $850 million for the current  fiscal year,  the lowest level since 1969. To
reduce  borrowing  costs and improve market access,  the Governor is proposing a
constitutional  amendment to limit issuance of appropriation bonds and to create
tax-backed debt.

  The State's updated  financial plan estimates that fiscal 1994 will achieve an
ending cash balance of approximately $299 million.  This larger than anticipated
surplus is a result of a  stabilizing  economy,  improving tax  collections  and
slowing  expenditure  growth. The 1993 and 1994 budgets were enacted in a timely
manner and were based on  realistic  economic  forecasts,  conservative  revenue
assumptions  and some spending  restraint.  The Governor's  proposed  budget for
fiscal  1995  provides  for general  fund  spending  growth of 4.3%,  use of the
current  year  surplus,  modest  tax  cuts and a small  level  of  non-recurring
measures. The fiscal 1995 financial plan is based on a forecast of slow economic
growth and projects increases in the personal income tax and user taxes and fees
of 5.3% and 4.1%, respectively.

  Significant  litigation exists at the State level of government.  A suit filed
by a taxpayer activist  challenges the  constitutionality  of the transportation
financing  plan.  Also, in November 1993, the Court of Appeals  affirmed a lower
court's  decision,  declaring that a change in the actuarial  funding method for
determining  contributions  by the  State  and its  local  governments  to their
respective retirement systems was unconstitutional. The State may also be liable
for  significant  payments  related to a U.S.  Supreme Court decision  involving
abandoned property.

  An  expanded   discussion   is  contained  in  the   statement  of  additional
information.

                     KEYSTONE PENNSYLVANIA TAX FREE FUND
DESCRIPTION OF STATE AND LOCAL TAX TREATMENT
  Individual  shareholders  of the  Pennsylvania  Fund  who are  subject  to the
Pennsylvania  personal income tax, as either  residents or  non-residents of the
Commonwealth  of  Pennsylvania,  will not be  subject to  Pennsylvania  personal
income tax on distributions  of interest made by the Pennsylvania  Fund that are
attributable to (1) obligations issued by the Commonwealth of Pennsylvania,  any
public  authority,  commission,  board or agency created by the  Commonwealth of
Pennsylvania,  any political  subdivision of the Commonwealth of Pennsylvania or
any public authority  created by any such political  subdivision  (collectively,
"Pennsylvania  Obligations");  and (2)  obligations  of the  United  States  and
certain qualifying agencies,  instrumentalities,  territories and possessions of
the United  States,  the  interest  from which are  statutorily  free from state
taxation in the Commonwealth of Pennsylvania  under the laws of the Commonwealth
or the U.S. (collectively,  "U.S. Obligations").  Distributions  attributable to
most other  sources will not be exempt from  Pennsylvania  personal  income tax.
Distributions  of  gains  attributable  to  Pennsylvania  Obligations  and  U.S.
Obligations   (collectively   "Exempt  Obligations")  will  be  subject  to  the
Pennsylvania personal income tax.

  Shares of the Pennsylvania  Fund that are held by individual  shareholders who
are Pennsylvania  residents subject to the Pennsylvania county personal property
tax will be exempt  from such tax to the  extent  that the  Pennsylvania  Fund's
portfolio  consists  of  Exempt  Obligations  on  the  annual  assessment  date.
Nonresidents  of  the  Commonwealth  of  Pennsylvania  are  not  subject  to the
Pennsylvania  county  personal  property  tax.  Corporations  are not subject to
Pennsylvania  personal property taxes. For shareholders who are residents of the
City of Philadelphia,  distributions of interest derived from Exempt Obligations
are not taxable for  purposes of the  Philadelphia  School  District  investment
income tax provided  that the  Pennsylvania  Fund reports to its  investors  the
percentage of Exempt  Obligations held by it for the year. The Pennsylvania Fund
will report such percentage to its shareholders.

  Distributions of interest,  but not gains,  realized on Exempt Obligations are
not  subject to the  Pennsylvania  corporate  net income tax.  The  Pennsylvania
Department  of Revenue also takes the position  that shares of funds  similar to
the Pennsylvania  Fund are not considered exempt assets of a corporation for the
purpose of  determining  its capital stock value  subject to the  Commonwealth's
capital stock and franchise taxes.

SPECIAL FACTORS AFFECTING THE PENNSYLVANIA FUND

  Historically,  Pennsylvania is among the leading states in  manufacturing  and
mining,  and its steel and coal  industries  have been of  national  importance.
However,  due in  part  to  the  decline  in  the  steel  and  coal  industries,
Pennsylvania's  economy has become more  diversified,  with major new sources of
growth in the service and trade sectors. The Commonwealth's unemployment rate is
below the  national  average,  and its per capita  income is slightly  above the
national  average.  The  Commonwealth's  General  Fund,  through which taxes are
received and debt service is made, had unappropriated  balance surpluses for the
years ended June 30, 1992 and June 30, 1993.

  The  Pennsylvania  Fund's yield and share price  stability are tied in part to
conditions  within  the  Commonwealth.  Changes  in  economic  conditions  in or
governmental policies of the Commonwealth could have a significant impact on the
performance  of  Pennsylvania  Obligations  held by the  Pennsylvania  Fund. For
example, the Commonwealth's  continued  dependence on manufacturing,  mining and
steel has made the Commonwealth  vulnerable to cyclical  industry  fluctuations,
foreign  imports  and  environmental  concerns.  Growth in the service and trade
sectors, however, has helped diversify the Commonwealth's economy and reduce its
unemployment  rate  below  the  national  average.  Changes  in  local  economic
conditions or local  governmental  policies within the  Commonwealth,  which can
vary  substantially  by  region,  could  also have a  significant  impact on the
performance of municipal  obligations held by the  Pennsylvania  Fund. Also, the
Pennsylvania  Fund will invest in obligations that are secured by obligors other
than  the  Commonwealth  or  its  political  subdivisions  (such  as  hospitals,
universities,  corporate obligors and corporate credit and liquidity  providers)
and  obligations  limited to specific  revenue  pledges (such as sewer authority
bonds).  The  creditworthiness  of  these  obligors  may  be  wholly  or  partly
independent  of the  creditworthiness  of  the  Commonwealth  or  its  municipal
authorities.  The Trustees of the Pennsylvania Fund have the power,  however, to
eliminate unsafe investments.

  An  expanded   discussion   is  contained  in  the   statement  of  additional
information.

                         KEYSTONE TEXAS TAX FREE FUND

DESCRIPTION OF STATE AND LOCAL TAX TREATMENT

  Texas does not presently  impose an income tax on individuals or corporations.
Consequently,  neither individual nor corporate  shareholders will be subject to
any Texas state income tax on distributions  received from the Texas Fund. Texas
does, however, impose a corporate franchise tax on corporations that do business
in Texas or are chartered or  authorized to do business in Texas.  The corporate
franchise tax imposed on those corporations is an amount equal to the greater of
(1) 1/4 of 1% of the corporation's  "taxable capital" apportioned to Texas, less
certain  deductions,  or (2) 4.5% of the corporation's  "taxable earned surplus"
apportioned to Texas, less certain deductions and loss carryforwards. The amount
of "taxable earned surplus" is based generally on the corporation's  "reportable
federal  taxable income" as computed under the Code.  Exempt interest  dividends
distributed  by the Texas  Fund are  expected  to be  excluded  from  reportable
federal  taxable  income by federal law and likewise  excluded  from the taxable
earned  surplus  component upon which the Texas  corporate  franchise tax may be
imposed.  Corporations  that do business in Texas or are chartered or authorized
to do business in Texas should consult their own tax advisors regarding the full
impact of the Texas franchise tax.

  Under  present  law,  the Texas Fund will not be  subject  to Texas  corporate
franchise tax.

SPECIAL FACTORS AFFECTING THE TEXAS FUND

  Texas'  economy  continues  to recover  from the  recession  that began in the
mid-1980s  after a collapse in oil  prices,  and the State  comptroller  expects
continued growth in the early 1990s. Also, since the mid-1980's, the economy has
diversified,  with the oil and gas industry  diminishing in relative  importance
while service-producing sectors provide the major sources of job growth.

  Based on information from the Texas Employment Commission, non-farm employment
has reached an all-time high of 7.8 million.  The unemployment  rate for 1994 is
estimated  at 6.4 percent  compared to a national  average of 6.1  percent.  The
Texas State  Government  ended fiscal year 1994 with a positive  cash balance in
the General  Fund.  This was the seventh  consecutive  year that the Texas State
Government had ended a fiscal year with a positive balance.

  On January 30, 1995, the Texas Supreme Court upheld the constitutionality of a
comprehensive  legislative revision to the system for financing the operation of
public  schools.  The  legislative  revisions  resulted  from a series  of court
decisions  commonly referred to as Edgewood v. Kirby, in which Texas courts have
declared the Texas school finance system  unconstitutional  under Texas law. The
Supreme Court's ruling  suggested that further changes might be needed in Texas'
school  finance  system in the near  future to  equalize  access to funding  for
capital  projects,  as well as  operations.  The Texas  Legislature is currently
considering  legislation  which  attempts  to  provide  such  equalization.  The
legislative  revision and further  efforts to equalize school funding may affect
the financial  condition of the Texas State  Government and certain Texas school
districts.

  Although it is anticipated  that most of the bonds held by the Texas Fund will
be  revenue   obligations  or  general   obligations  of  local  governments  or
authorities,  rather than general  obligations of the State of Texas itself, any
circumstances  that adversely affect the State's credit standing may also affect
the market value of these other bonds held by the Texas Fund, either directly or
indirectly,  as  a  result  of a  dependency  of  local  governments  and  other
authorities upon State aid and reimbursement programs.

  An  expanded   discussion   is  contained  in  the   statement  of  additional
information.

                                                                       EXHIBIT B

                             REDUCED SALES CHARGES

  Initial  sales   charges  may  be  reduced  or   eliminated   for  persons  or
organizations  purchasing  Class A shares of a Fund alone or in combination with
Class A shares of other Keystone America Funds.

  For  purposes  of  qualifying  for reduced  sales  charges on  purchases  made
pursuant to Rights of  Accumulation or Letters of Intent,  the term  "Purchaser"
includes the following persons: an individual; an individual,  his or her spouse
and children under the age of 21; a trustee or other fiduciary of a single trust
estate  or  single  fiduciary   account   established  for  their  benefit;   an
organization  exempt from federal income tax under Section 501 (c)(3) or (13) of
the Code; a pension,  profit-sharing  or other employee  benefit plan whether or
not qualified under Section 401 of the Internal Revenue Code; or other organized
groups of persons,  whether  incorporated or not,  provided the organization has
been in existence  for at least six months and has some  purpose  other than the
purchase  of  redeemable  securities  of a  registered  investment  company at a
discount.  In order to qualify  for a lower  sales  charge,  all orders  from an
organized  group will have to be placed  through a single  investment  dealer or
other firm and identified as originating from a qualifying purchaser.

CONCURRENT PURCHASES

  For purposes of qualifying for a reduced sales charge, a Purchaser may combine
concurrent  direct  purchases of Class A shares of two or more of the  "Eligible
Funds," as defined  below.  For example,  if a Purchaser  concurrently  invested
$75,000 in one of the other  "Eligible  Funds" and $75,000 in a Fund,  the sales
charge  would be that  applicable  to a $150,000  purchase,  i.e.,  3.75% of the
offering price, as indicated in the Sales Charge schedule in the prospectus.

RIGHT OF ACCUMULATION

  In calculating  the sales charge  applicable to current  purchases of a Fund's
shares, a Purchaser is entitled to accumulate current purchases with the current
value of previously  purchased  Class A shares of the Fund and Class A shares of
certain other  eligible funds that are still held in (or exchanged for shares of
and are still held in) the same or another  eligible fund ("Eligible  Fund(s)").
The Eligible Funds presently  consist of the Keystone America Funds and Keystone
Liquid Trust.

  For example,  if a Purchaser  held shares  valued at $99,999 and  purchased an
additional $5,000, the sales charge for the $5,000 purchase would be at the next
lower sales  charge of 3.75% of the  offering  price as  indicated  in the Sales
Charge  schedule.  KIRC  must be  notified  at the  time of  purchase  that  the
Purchaser is entitled to a reduced sales charge, which reduction will be granted
subject to confirmation of the Purchaser's  holdings.  The Right of Accumulation
may be modified or discontinued at any time.

LETTER OF INTENT

  A Purchaser  may qualify for a reduced  sales  charge on a purchase of Class A
shares of the Fund alone or in  combination  with purchases of Class A shares of
any of the other  Eligible  Funds by completing  the Letter of Intent section of
the  application.  By  doing  so,  the  Purchaser  agrees  to  invest  within  a
thirteen-month  period a specified amount, which, if invested at one time, would
qualify  for a reduced  sales  charge.  Each  purchase  will be made at a public
offering price applicable to a single transaction of the dollar amount specified
on the application,  as described in this prospectus.  The Letter of Intent does
not  obligate  the  Purchaser  to  purchase,  nor a Fund  to  sell,  the  amount
indicated.

  After the Letter of Intent is received by KIRC,  each  investment made will be
entitled to the sales charge applicable to the level of investment  indicated on
the  application.  The Letter of Intent may be  back-dated  up to ninety days so
that any  investments  made in any of the Eligible  Funds  during the  preceding
ninety-day  period,  valued  at the  Purchaser's  cost,  can be  applied  toward
fulfillment of the Letter of Intent.  However,  there will be no refund of sales
charges  already paid during the ninety-day  period.  No retroactive  adjustment
will be made if purchases  exceed the amount  specified in the Letter of Intent.
Income and capital gains distributions taken in additional shares will not apply
toward completion of the Letter of Intent.

  If total  purchases  made  pursuant  to the Letter of Intent are less than the
amount specified, the Purchaser will be required to remit an amount equal to the
difference  between the sales  charge paid and the sales  charge  applicable  to
purchases  actually made. Out of the initial purchase (or subsequent  purchases,
if necessary), 5% of the dollar amount specified on the application will be held
in escrow by KIRC in the form of shares  registered in the Purchaser's name. The
escrowed shares will not be available for redemption, transfer or encumbrance by
the Purchaser until the Letter of Intent is completed or the higher sales charge
paid. All income and capital gains distributions on escrowed shares will be paid
to the Purchaser or his order.

  When the minimum  investment  specified  in the Letter of Intent is  completed
(either prior to or by the end of the thirteen-month period), the Purchaser will
be notified and the escrowed shares will be released. If the intended investment
is not  completed,  the  Purchaser  will be  asked  to  remit  to the  Principal
Underwriter any difference  between the sales charge on the amount specified and
on the amount actually attained.  If the Purchaser does not within 20 days after
written  request by the Principal  Underwriter or his dealer pay such difference
in sales charge,  KIRC will redeem an appropriate  number of the escrowed shares
in order to realize such difference.  Shares remaining after any such redemption
will be released  by KIRC.  Any  redemptions  made by the  Purchaser  during the
thirteen-month  period will be  subtracted  from the amount of the purchases for
purposes of determining whether the Letter of Intent has been completed.  In the
event of a total  redemption of the account prior to completion of the Letter of
Intent,  the  additional  sales charge due will be deducted from the proceeds of
the redemption and the balance will be forwarded to the Purchaser.

  By signing the application, the Purchaser irrevocably constitutes and appoints
KIRC his attorney to surrender for  redemption  any or all escrowed  shares with
full power of substitution.

  The Purchaser or his dealer must inform the Principal Underwriter or KIRC that
a Letter of Intent is in effect each time a purchase is made.

                             THE FUND
- -------------------------------------------------------------------------------

         The FUND is a non-diversified,  open-end management  investment company
commonly known as a mutual fund. The FUND was formed as a Massachusetts business
trust on  September  13, 1990.  The FUND is one of the thirty  funds  managed or
advised by Keystone  Investment  Management  Company  (formerly  named  Keystone
Custodian Funds, Inc.)  ("Keystone"),  the FUND's investment  adviser.  The FUND
currently consists of the following five separate series evidencing interests in
different  portfolios of securities:  Keystone  Florida Tax Free Fund,  Keystone
Massachusetts Tax Free Fund,  Keystone New York Insured Tax Free Fund,  Keystone
Pennsylvania Tax Free Fund and Keystone Texas Tax Free Fund (each, a "Fund," and
collectively,   the   "Funds").   The  Keystone   Pennsylvania   Tax  Free  Fund
("Pennsylvania  Fund") and the Keystone  Florida Tax Free Fund ("Florida  Fund")
were established on September 19, 1990. The Keystone Massachusetts Tax Free Fund
("Massachusetts  Fund"),  the Keystone New York Insured Tax Free Fund ("New York
Insured  Fund")  and the  Keystone  Texas  Tax Free  Fund  ("Texas  Fund")  were
established  on  February  21,  1992.  The  Massachusetts  Fund and the New York
Insured Fund were not offered to the public prior to February 4, 1994.

         The essential  information about the FUND and its Funds is contained in
its prospectus.  This statement of additional  information  provides  additional
information  about  the  FUND and its  Funds  that  may be of  interest  to some
investors.

         For  special  factors  affecting  each  Fund,  see  Appendix  A to this
statement of additional information.

                            INVESTMENT POLICIES
- -------------------------------------------------------------------------------

         Each Fund invests  primarily in municipal  obligations  that are exempt
from  federal  income tax and also exempt from  certain  specified  taxes in the
state for which it is named.  In  addition,  the Funds  invest in certain  other
securities as described below.

MUNICIPAL OBLIGATIONS

         Municipal  obligations  include debt obligations issued by or on behalf
of a state,  a territory  or a possession  of the United  States  ("U.S."),  the
District of Columbia or any  political  subdivision,  agency or  instrumentality
thereof (for example, counties, cities, towns, villages, districts, authorities)
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 and water and sewer  works.
Other public purposes for which municipal  obligations may be issued include the
refunding of  outstanding  obligations,  obtaining  funds for general  operating
expenses and obtaining funds to lend to public or private  institutions  for the
construction  of  facilities,   such  as   educational,   hospital  and  housing
facilities. In addition, certain types of industrial development bonds have been
or may be  issued  by or on behalf of  public  authorities  to  finance  certain
privately-operated  facilities,  and certain local  facilities for water supply,
gas,  electricity  or sewage  or solid  waste  disposal.  Such  obligations  are
included  within the term  municipal  obligations  if the interest  paid thereon
qualifies as fully exempt from federal  income tax. The income of certain  types
of  industrial  development  bonds  used to finance  certain  privately-operated
facilities (qualified private activity bonds) issued after August 7, 1986, while
exempt  from  federal  income  tax,  is  includable  for  the  purposes  of  the
calculation  of  the   alternative   minimum  tax.  Other  types  of  industrial
development  bonds,  the  proceeds  from  which  are used for the  construction,
equipment,  repair or improvement of privately operated industrial or commercial
facilities,  may constitute municipal obligations,  although the current federal
tax laws place substantial limitations on the size of such issues.

         The two principal classifications of municipal obligations are "general
obligation" and limited obligation or "revenue" bonds.  General obligation bonds
are obligations  involving the credit of an issuer  possessing  taxing power and
are payable from the  issuer's  general  unrestricted  revenues and not from any
particular  fund or revenue  source.  Their  payment  may be  dependent  upon an
appropriation   by  the  issuer's   legislative  body  and  may  be  subject  to
quantitative  limitations on the issuer's taxing power. The  characteristics and
methods of  enforcement  of general  obligation  bonds vary according to the law
applicable to the  particular  issuer.  Limited  obligation or 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 or other
specific  revenue  source,  such  as  the  user  of  the  facility.   Industrial
development  bonds that are municipal  obligations  are, in most cases,  revenue
bonds and  generally  are not  payable  from the  unrestricted  revenues  of the
issuer.  The credit quality of industrial  development  revenue bonds is usually
directly  related to the credit standing of the owner or user of the facilities.
There are, of course, variations in the security of municipal obligations,  both
within a particular  classification  and between  classifications,  depending on
numerous factors.

         The  yields on  municipal  obligations  are  dependent  on a variety of
factors,  including general money market conditions,  the financial condition of
the issuer,  general conditions of the municipal  obligations  market, size of a
particular offering, and the maturity of the obligation and rating of the issue.
The ratings of Moody's Investors Service,  Inc.  ("Moody's"),  Standard & Poor's
Corporation ("S&P") and Fitch Investor Services,  Inc,  ("Fitch"),  as described
below,  represent their opinions as to the quality of the municipal  obligations
that they undertake to rate. It should be emphasized,  however, that ratings are
general  and  not  absolute  standards  of  quality.   Consequently,   municipal
obligations with the same maturity,  interest rate and rating may have different
yields while  municipal  obligations of the same maturity and interest rate with
different  ratings  may have the same  yield.  It should  also be noted that the
standards of disclosure  applicable to and the amount of information relating to
the financial condition of issuers of municipal obligations are not as extensive
as those generally relating to corporations.

         Subsequent to its purchase by a Fund, an issue of municipal obligations
or other investment may cease to be rated or its rating may be reduced below the
minimum  rating  required for purchase by the Fund.  Neither event  requires the
elimination  of such  obligation  from the Fund's  portfolio,  but Keystone will
consider such an event in its  determination of whether the Fund should continue
to hold such obligation in its portfolio.

         The  ability  of each Fund to  achieve  its  investment  objectives  is
dependent  upon the  continuing  ability of issuers of municipal  obligations to
meet their  obligations to pay interest and principal  when due.  Obligations of
issuers of municipal  obligations  are subject to the  provisions of bankruptcy,
insolvency and other laws  affecting the rights and remedies of creditors,  such
as the federal Bankruptcy Act, and laws, if any, that may be enacted by Congress
or state  legislatures  extending the time for payment of principal or interest,
or both, or imposing other  constraints  upon  enforcement of such  obligations.
There  is  also  the  possibility  that  as a  result  of  litigation  or  other
conditions,  the power or ability of any one or more  issuers to pay,  when due,
principal  of  and  interest  on  its  or  their  municipal  obligations  may be
materially affected. In addition,  the market for municipal obligations is often
thin and can be  temporarily  affected by large  purchases and sales,  including
those by a Fund.

         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 obligations,  and similar proposals may well be introduced
in the future.  If such a proposal were enacted,  the  availability of municipal
obligations  for investment by the Funds and the value of the Funds'  portfolios
could be  materially  affected,  in which  event the FUND would  reevaluate  the
investment  objective  and  policies  of its Funds and  consider  changes in the
structure of the Funds or dissolution.

         The Tax Reform Act of 1986 made significant  changes in the federal tax
status of certain  obligations that were previously fully federally  tax-exempt.
As a result,  three categories of such  obligations  issued after August 7, 1986
now exist: (1)"public purpose" bonds, the income from which remains fully exempt
from federal income tax; (2) qualified "private activity" industrial development
bonds, the income from which, while exempt from federal income tax under Section
103 of the Internal  Revenue Code of 1986, as amended (the "Code") is includable
in the  calculation  of the federal  alternative  minimum  tax; and (3) "private
activity"  (private  purpose)  bonds,  the income  from which is not exempt from
federal income tax. A Fund will not invest in private  purpose bonds and, except
as described  under "Other Eligible  Investments,"  will not invest in qualified
"private activity" industrial  development bonds whose distributions are subject
to the alternative minimum tax.

OTHER ELIGIBLE INVESTMENTS

         A Fund may invest up to 20% of its assets under ordinary circumstances,
and up to 100% of its assets for temporary  defensive  purposes in the following
types of instruments:  (1) commercial paper, including master demand notes, that
at the date of investment is rated A-1 (the highest grade by S&P),  PRIME-1 (the
highest  grade by  Moody's)  or, if not rated by such  services,  is issued by a
company  that at the date of  investment  has an  outstanding  issue  rated A or
better by S&P or Moody's; (2) obligations, including certificates of deposit and
bankers' acceptances,  of banks, or savings and loan associations,  that have at
least $1  billion  in assets  as of the date of their  most  recently  published
financial   statements  that  are  members  of  the  Federal  Deposit  Insurance
Corporation,  including U.S.  branches of foreign banks and foreign  branches of
U.S. banks;  (3) corporate  obligations  (maturing in 13 months or less) that at
the date of investment are rated A or better by S&P or Moody's;  (4) obligations
issued or guaranteed by the U.S.  government or by any agency or instrumentality
of the U.S.; (5) qualified "private activity"  industrial  development bonds the
income from which, while exempt from federal income tax under Section 103 of the
Code, is includable in the calculation of the federal  alternative  minimum tax;
and (6) municipal obligations, the income of which is exempt from federal income
tax,  but not exempt  from income tax in  Pennsylvania,  or which are not exempt
from personal  property or intangibles  tax in Florida or  Pennsylvania,  as the
case may be. Each Fund will  assume a temporary  defensive  position  when,  for
example,  Keystone  determines that market  conditions so warrant.  If a Fund is
investing defensively, it is not pursuing its objectives.

FUNDAMENTAL NATURE OF INVESTMENT OBJECTIVES

         The investment  objectives of each Fund are  fundamental and may not be
changed without approval of the holders of a majority of such Fund's outstanding
voting shares (which means the lesser of (1) 67% of the shares  represented at a
meeting at which more than 50% of the outstanding  shares are represented or (2)
more than 50% of the outstanding shares).

- -------------------------------------------------------------------------------
                        INVESTMENT RESTRICTIONS
- -------------------------------------------------------------------------------

         The investment  restrictions  as summarized  below are  fundamental for
each Fund and may not be changed  without  the vote of a majority of such Fund's
outstanding voting shares. Unless otherwise stated, all references to the assets
of a Fund  are in  terms  of  current  market  value.  Each  Fund may not do the
following:

         (1) purchase any security of any issuer  (other than issues of the U.S.
government,  its agencies or  instrumentalities) if as a result more than 25% of
its total assets would be invested in a single industry, including in industrial
development  bonds  from the  same  facility  or  similar  types of  facilities;
governmental  issuers  of  municipal  bonds are not  regarded  as  members of an
industry  and a Fund may  invest  more  than  25% of its  assets  in  industrial
development bonds;

         (2)  invest  more than 10% of its  assets in  securities  with legal or
contractual  restrictions on resale or in securities for which market quotations
are not readily  available,  or in repurchase  agreements  maturing in more than
seven days;

         (3) issue senior  securities;  the purchase or sale of  securities on a
"when issued" basis,  or collateral  arrangement  with respect to the writing of
options on securities, are not deemed to be the issuance of a senior security;

         (4) borrow money or enter into reverse  repurchase  agreements,  except
that a Fund may enter into reverse  repurchase  agreements  or borrow money from
banks for temporary or emergency  purposes in aggregate  amounts up to one-third
of the value of the Fund's net assets; provided that while borrowings from banks
(not  including  reverse  repurchase  agreements)  exceed 5% of the  Fund's  net
assets,  any such  borrowings will be repaid before  additional  investments are
made;

         (5)  purchase  securities  on margin  except  that it may  obtain  such
short-term  credit as may be necessary  for the clearance of purchases and sales
of securities;

         (6) make loans, except that a Fund may purchase or hold debt securities
consistent with its investment  objectives,  lend portfolio securities valued at
not  more  than  15% of its  total  assets  to  broker-dealers  and  enter  into
repurchase agreements;

         (7) purchase securities of other investment  companies,  except as part
of a merger, consolidation, purchase of assets or similar transaction;

         (8) purchase or sell commodities or commodity contracts or real estate,
except  that it may  purchase  and sell  securities  secured by real  estate and
securities of companies which invest in real estate,  and may engage in currency
or other financial futures contracts and related options transactions; or

         (9) underwrite  securities of other  issuers,  except that the Fund may
purchase  securities from the issuer or others and dispose of such securities in
a manner consistent with its investment objective.

         The Funds are  non-diversified  under the federal  securities  laws. As
non-diversified  Funds, there is no restriction under the Investment Company Act
of 1940  ("1940  Act") on the  percentage  of assets that may be invested at any
time in the securities of any one issuer.  The Funds intend to comply,  however,
with the Code's diversification  requirements and other requirements  applicable
to  "regulated  investment  companies"  so that they will not be subject to U.S.
federal income tax on income and capital gain distributions to shareholders. For
this reason,  each Fund has adopted the additional  investment  restriction  set
forth  below,  which may not be changed  without the  approval of  shareholders.
Specifically,  a Fund may not (1)  purchase a  security  if more than 25% of the
Fund's  total  assets  would be invested in the  securities  of a single  issuer
(other than the U.S.  government,  its agencies and  instrumentalities);  or (2)
with respect to 50% of the Fund's total  assets,  if more than 5% of such assets
would be  invested in the  securities  of a single  issuer  (other than the U.S.
government, its agencies and instrumentalities).

         To the  extent  the Funds are not fully  diversified,  they may be more
susceptible to adverse economic,  political or regulatory developments affecting
a  single  issuer  than  would  be the  case  if the  Funds  were  more  broadly
diversified.

         As a matter of practice, each Fund treats reverse repurchase agreements
as borrowings for purposes of compliance  with the  limitations of the 1940 Act.
Reverse  repurchase  agreements will be taken into account along with borrowings
from  banks for  purposes  of the 5% limit set forth in the  fourth  fundamental
investment restriction above.

         Additional  restrictions adopted for each Fund, which may be changed by
the Board of Trustees, provide that a Fund may not purchase or retain securities
of an issuer if, to the knowledge of the FUND,  officers,  Trustees or Directors
of the FUND or  Keystone  each  owning  beneficially  more than 1/2 of 1% of the
securities of such issuer own in the aggregate more than 5% of the securities of
such  issuer,  or such persons or  management  personnel of the FUND or Keystone
have a  substantial  beneficial  interest  in the  securities  of  such  issuer.
Portfolio  securities  of a Fund may not be purchased  from or sold or loaned to
Keystone  or any  affiliate  thereof  or any of  their  Directors,  officers  or
employees.

         None of the Funds  presently  intends  to  invest  more than 25% of its
total assets in municipal  obligations  the payment of which depends on revenues
derived from a single  facility or similar  types of  facilities.  Since certain
municipal obligations may be related in such a way that an economic, business or
political  development  or change  affecting  one such security  could  likewise
affect the other  securities,  a change in this policy could result in increased
investment risk, but no change is presently contemplated.

         For  the  purposes  of  the  first  and  ninth  fundamental  investment
restrictions set forth above, each Fund will treat (1) each state, territory and
possession of the U.S., the District of Columbia and, if its assets and revenues
are separate  from those of the entity or entities  creating it, each  political
subdivision, agency and instrumentality of any one (or more, as in the case of a
multistate  authority or agency) of the foregoing as an issuer of all securities
that are backed  primarily  by its assets or  revenues;  (2) each  company as an
issuer of all  securities  that are backed  primarily by its assets or revenues;
and (3) each of the foregoing  entities as an issuer of all  securities  that it
guarantees;  provided,  however,  that for the purpose of the first  fundamental
investment  restriction  no entity shall be deemed to be an issuer of a security
that it  guarantees  so long as no more than 10% of a Fund's total assets (taken
at current  value)  are  invested  in  securities  guaranteed  by the entity and
securities of which it is otherwise deemed to be an issuer.

         The Texas Fund has undertaken to a state securities  authority that, so
long as the state  authority  requires and shares of the Fund are registered for
sale in that  state,  (1) the Fund will not  purchase  puts,  calls,  straddles,
spreads or combinations thereof, if by reason thereof the value of its aggregate
investment in such  securities will exceed 5% of its total assets except that it
may purchase  "stand-by  commitments"  and master demand notes; and (2) the Fund
will maintain 300% asset coverage on any leverage or bank borrowings.

         The FUND has undertaken to a state  securities  authority that, so long
as the state authority  requires and shares of a Fund are registered for sale in
that state,  the Fund will (1) not invest in real estate  limited  partnerships;
and (2) not invest in oil, gas or other mineral leases.

         Further,  the FUND has undertaken to a state securities authority that,
so long as the state authority  requires and shares of a Fund are registered for
sale in that state, all loans of portfolio securities will be made in accordance
with fair,  just and equitable  practice and the collateral  values of portfolio
securities loaned will be maintained at no less than 100% by "marking to market"
daily.

         In order to permit the sale of a Fund's shares in certain  states,  the
FUND may make  commitments  more  restrictive  than the investment  restrictions
described above. Should the FUND determine that any such commitment is no longer
in the best  interests of the affected  Fund,  it will revoke the  commitment by
terminating sales of its shares in the state involved.

         If a  percentage  limit  is  satisfied  at the  time of  investment  or
borrowing,  a later increase or decrease  resulting from a change in asset value
is not a violation of the limit.

- -------------------------------------------------------------------------------
                    VALUATION AND REDEMPTION OF SECURITIES
- -------------------------------------------------------------------------------

         Current values for each Fund's  portfolio  securities may be determined
in the following manner:

         1.  securities for which market  quotations  are readily  available are
valued at the mean of the bid and asked prices at the time of valuation;

         2.  (a)  instruments  having  maturities  of  sixty  days or less  when
purchased are valued at amortized cost  (original  purchase cost as adjusted for
amortization  of premium or accretion of  discount),  which,  when combined with
accrued interest, approximates market;

            (b) investments maturing in more than sixty days when purchased that
are held on the  sixtieth  day prior to maturity  are valued at  amortized  cost
(market  value on the  sixtieth  day  adjusted  for  amortization  of premium or
accretion of discount), which, when combined with accrued interest, approximates
market;  and which,  in either case,  reflects  fair value as  determined by the
FUND's Board of Trustees;

         3. short-term instruments having maturities of more than sixty days for
which  market  quotations  are readily  available  are valued at current  market
value; and

         4. the following  securities  are valued at prices deemed in good faith
to  be  fair  under  procedures  established  by  the  Board  of  Trustees:  (a)
securities, including restricted securities, for which market quotations are not
readily available; and (b) other assets.

         The FUND  believes that reliable  market  quotations  are generally not
readily  available for purposes of valuing municipal  obligations.  As a result,
depending on the particular municipal  obligations owned by a Fund, it is likely
that most of the valuations for such  obligations  will be based upon their fair
value determined under procedures  approved by the Board of Trustees.  The Board
of Trustees has  authorized  the use of a pricing  service to determine the fair
value of each Fund's  municipal  obligations and certain other  securities.  Non
tax-exempt  securities  for which market  quotations  are readily  available are
valued on a consistent  basis at that price quoted which,  in the opinion of the
Board of Trustees or the person  designated by the Board of Trustees to make the
determination,  most  nearly  represents  the  market  value  of the  particular
security.  Any securities for which market  quotations are not readily available
or other assets are valued on a consistent  basis at fair value as determined in
good faith using methods prescribed by the FUND's Board of Trustees.

         The FUND has obligated itself under the 1940 Act to redeem for cash all
shares  presented for redemption by any one  shareholder in any 90 day period up
to the lesser of $250,000 or 1% of a Fund's assets.

- -------------------------------------------------------------------------------
                                SALES CHARGES
- -------------------------------------------------------------------------------

GENERAL

         Generally, each Fund offers three classes of shares. Class A shares are
offered with a maximum  front end sales  charge of 4.75%  payable at the time of
purchase of Fund shares ("Front End Load Option").  Class B shares  purchased on
or after June 1, 1995 are subject to a contingent  deferred sales charge payable
upon  redemption  during the 72 month  period  following  the month of purchase.
Class B shares  purchased prior to June 1, 1995 are sold subject to a contingent
deferred sales charge payable upon redemption  within three calendar years after
the first year of purchase ("Back End Load Option"). Class B shares purchased on
or after June 1, 1995 that have been outstanding eight years following the month
of purchase will automatically convert to Class A shares without imposition of a
front-end  sales charge or exchange fee. Class B shares  purchased prior to June
1, 1995 that have been  outstanding  during seven  calendar years will similarly
convert to Class A shares.  (Conversion  of Class B shares  represented by stock
certificates  will  require  the return of the stock  certificates  to  Keystone
Investment Resource Center, Inc. ("KIRC").) Class C shares are sold subject to a
contingent  deferred sales charge payable upon redemption  within one year after
purchase  ("Level  Load  Option").  Class C shares are  available  only  through
dealers who have entered into special  distribution  agreements  with the FUND's
Principal  Underwriter.  The FUND's prospectus contains a general description of
how investors may buy shares of the FUND as well as a table of applicable  sales
charges for Class A shares, a discussion of reduced sales charges  applicable to
subsequent purchases,  and a description of applicable contingent deferred sales
charges.

CONTINGENT DEFERRED SALES CHARGES

         In order to reimburse a Fund for certain expenses  relating to the sale
of its shares (See "Distribution  Plans"), a contingent deferred sales charge is
imposed at the time of redemption of certain Fund shares, as follows:

CLASS A SHARES

         With certain  exceptions,  purchases of Class A shares made on or after
April 10, 1995 (1) in an amount equal to or exceeding $1,000,000 and/or (2) by a
corporate  qualified  retirement plan or a non-qualified  deferred  compensation
plan  sponsored  by a  corporation  having  100 or more  eligible  employees  (a
"Qualifying  Plan"),  in either case without a front-end  sales charge,  will be
subject  to a  contingent  deferred  sales  charge of 0.50%  during the 24 month
period following the date of purchase.  Certain Class A shares purchased without
a front-end  sales charge prior to April 10, 1995 may be subject to a contingent
deferred  sales  charge of 0.25%  upon  redemption  during the  one-year  period
commencing on the date such shares were  originally  purchased.  The  contingent
deferred  sales  charge  will be  retained  by the  Principal  Underwriter.  See
"Calculation of Contingent Deferred Sales Charge" below.

CLASS B SHARES

         With respect to Class B shares purchased on or after June 1, 1995, each
Fund,  with  certain  exceptions,  will  impose a  deferred  sales  charge  as a
percentage  of the lesser of net asset  value or net cost of such Class B shares
redeemed during succeeding  twelve-month periods following the month of purchase
as follows:  5% during the first period;  4% during the second period; 3% during
the third period; 3% during the fourth period;  2% during the fifth period,  and
1% during  the sixth  period.  No  deferred  sales  charge is imposed on amounts
redeemed thereafter.

         With respect to Class B shares  purchased  prior to June 1, 1995,  each
Fund, with certain  exceptions,  will impose a deferred sales charge of 3.00% on
shares  redeemed  during  the  calendar  year of  purchase  and during the first
calendar  year  after  purchase;  2.00% on shares  redeemed  during  the  second
calendar  year after  purchase;  and 1.00% on shares  redeemed  during the third
calendar  year after  purchase.  No deferred  sales charge is imposed on amounts
redeemed thereafter.

         When imposed, the deferred sales charge is deducted from the redemption
proceeds otherwise payable to you. Amounts received by the Principal Underwriter
under the Class B  Distribution  Plans are  reduced by  deferred  sales  charges
retained by the Principal  Underwriter.  See "Calculation of Contingent Deferred
Sales Charge" below.

CLASS C SHARES

         With certain  exceptions,  a Fund may impose a deferred sales charge of
1% on shares  redeemed  within one year after the date of purchase.  No deferred
sales charge is imposed on amounts redeemed thereafter.

         When imposed, the deferred sales charge is deducted from the redemption
proceeds  otherwise payable to you. The deferred sales charge is retained by the
Principal  Underwriter.  See  "Calculation of Contingent  Deferred Sales Charge"
below.

CALCULATION OF CONTINGENT DEFERRED SALES CHARGE

         Any  contingent  deferred  sales charge  imposed upon the redemption of
Class A, Class B or Class C shares is a percentage  of the lesser of (1) the net
asset  value  of the  shares  redeemed  or (2) the net  asset  value  at time of
purchase of such shares.

         No contingent  deferred  sales charge is imposed when amounts  redeemed
are derived from (1)  increases in the value of an account above the net cost of
such shares due to  increases  in the net asset  value per share of a Fund;  (2)
certain  shares  with  respect  to  which a Fund  did not  pay a  commission  on
issuance,  including shares acquired through reinvestment of dividend income and
capital gains  distributions;  (3) Certain Class A shares held for more than one
year or two years,  as the case may be, from the date of  purchase;  (4) Class B
shares  held during more than four  consecutive  calendar  years or more than 72
months  after the month of  purchase,  as the case may be; or (5) Class C shares
held for more than one year from date of purchase.

         Upon  request  for  redemption,  shares not  subject to the  contingent
deferred  sales  charge  will be  redeemed  first.  Thereafter,  shares held the
longest will be the first to be redeemed.  There is no contingent deferred sales
charge when the shares of a class are exchanged for the shares of the same class
of another Keystone America Fund.  Moreover,  when shares of one such class of a
fund  have been  exchanged  for  shares of  another  such  class of a fund,  the
calendar  year of the  exchange  is assumed to be the year shares  tendered  for
exchange were originally purchased.

WAIVER OF SALES CHARGES

         Class A,  Class B or Class C shares of each  Fund may also be sold,  to
the  extent  permitted  by  applicable  law,  regulations,   interpretations  or
exemptions, at net asset value without the imposition of an initial sales charge
to (1) certain  officers,  Directors,  Trustees,  full-time  employees and sales
representatives   of  the  FUND,   Keystone   Management,   Keystone,   Keystone
Investments, Inc. (formerly Keystone Group, Inc.), ("Keystone Investments"), one
of their subsidiaries or the Principal  Underwriter,  who have been such for not
less than ninety days; (2) a pension and profit-sharing plan established by such
companies, their subsidiaries and affiliates, for the benefit of their officers,
Directors,  Trustees,  full-time employees and sales  representatives;  or (3) a
registered  representative  of a firm with a dealer agreement with the Principal
Underwriter,  provided,  however,  that all such sales are made upon the written
assurance  that  the  purchase  is made  for  investment  purposes  and that the
securities will not be resold except through redemption by the FUND.

         No initial sales charge is charged on a purchase of shares of a Fund by
a bank or trust  company  in a single  account in the name of such bank or trust
company as trustee if the  initial  investment  in shares of one of the Funds or
any fund in the Keystone Investments Family of Funds is at least $500,000.

         In  addition,  no  contingent  deferred  sales  charge is  imposed on a
redemption  of shares of a Fund in the event of (1) death or  disability  of the
shareholder; (2) a lump-sum distribution from a benefit plan qualified under the
Employee  Retirement  Income  Security  Act of  1974  ("ERISA");  (3)  automatic
withdrawals  from ERISA plans if the  shareholder  is at least 59 1/2 years old;
(4) involuntary redemptions of an account having an aggregate net asset value of
less than $1,000; (5) automatic  withdrawals under an automatic  withdrawal plan
of up to 1 1/2% per month of the  shareholder's  initial  account  balance;  (6)
withdrawals  consisting of loan proceeds to a retirement plan  participant;  (7)
financial  hardship  withdrawals made by a retirement plan  participant;  or (8)
withdrawals  consisting of returns of excess  contributions  or excess  deferral
amounts made to a retirement plan participant.

                             DISTRIBUTION PLANS
- --------------------------------------------------------------------------------

         Rule 12b-1 under the 1940 Act permits investment companies, such as the
FUND, to use their assets to bear expenses of distributing  their shares if they
comply  with  various  conditions,  including  adoption of a  distribution  plan
containing  certain  provisions set forth in Rule 12b-1.  Each Fund's Class A, B
and C  Distribution  Plans have been  approved by the FUND's  Board of Trustees,
including a majority of the Trustees who are not interested persons of the FUND,
as defined in the 1940 Act ("Independent  Trustees"),  and the Trustees who have
no  direct  or  indirect  financial  interest  in the  Distribution  Plan or any
agreement  related  thereto (the "Rule 12b-1  Trustees," who are the same as the
Independent Trustees). Each Class A, B, and C Distribution Plan, a "Distribution
Plan," and collectively, "Distribution Plans".

DISTRIBUTION PLANS IN GENERAL

         The National Association of Securities Dealers, Inc. ("NASD") currently
limits the amount that a Fund may pay annually in distribution costs for sale of
its shares and shareholder  service fees. The rule limits annual expenditures to
1% of the aggregate  average daily net asset value of its shares, of which 0.75%
may be  used  to pay  such  distribution  costs  and  0.25%  may be  used to pay
shareholder  service fees. The NASD rule also limits the aggregate amount that a
Fund may pay for such distribution costs to 6.25% of gross share sales since the
inception  of the 12b-1  Plan,  plus  interest at the prime rate plus 1% on such
amounts (less any contingent  deferred sales charges paid by shareholders to the
Principal Underwriter).

CLASS A DISTRIBUTION PLAN

         The Class A  Distribution  Plan  provides  that a Fund may expend daily
amounts at an annual rate currently limited to up to 0.15% of the Fund's average
daily net asset value  attributable  to Class A shares to finance  any  activity
that is primarily  intended to result in the sale of Class A shares,  including,
without  limitation,   expenditures   consisting  of  payments  to  a  principal
underwriter  (currently  the  Principal  Underwriter)  of a Fund to  enable  the
Principal Underwriter to pay or to have paid to others who sell Class A shares a
service  or other  fee,  at such  intervals  as the  Principal  Underwriter  may
determine,  in respect of Class A shares  previously sold by any such others and
remaining  outstanding  during the period in respect of which such fee is or has
been paid.

         Amounts  paid  by a Fund  under  its  Class  A  Distribution  Plan  are
currently used to pay others, such as dealers, service fees at an annual rate of
up to 0.15% of the average net asset value of Class A shares sold by such others
and remaining outstanding on the books of the Fund for specific periods.

CLASS B DISTRIBUTION PLANS

         Each Fund has  adopted  Distribution  Plans for its Class B shares that
provide  that a Fund may expend  daily  amounts at an annual rate of up to 1.00%
(currently  limited  to  0.90%) of the  Fund's  average  daily  net asset  value
attributable  to  Class B shares  to  finance  any  activity  that is  primarily
intended to result in the sale of Class B shares, including, without limitation,
expenditures  consisting  of payments to the principal  underwriter  of the Fund
(currently the Principal Underwriter) (1) to enable the Principal Underwriter to
pay to others  (dealers)  commissions  in respect  of Class B shares  sold since
inception of the Distribution Plans; and (2) to enable the Principal Underwriter
to pay or to have  paid to  others  a  service  fee,  at such  intervals  as the
Principal Underwriter may determine,  in respect of Class B shares maintained by
any such recipients outstanding on the books of the Fund for specified periods.

         The  Principal  Underwriter  generally  reallows to brokers or others a
commission equal to 4.00% of the price paid for each Class B share sold plus the
first year's service fee in advance in the amount of 0.15% of the price paid for
each Class B share sold. Beginning approximately 12 months after the purchase of
a Class B share,  the broker or other party  receives  service fees at an annual
rate of  0.15% of the  average  daily  net  asset  value  of such  Class B share
maintained by the recipient  outstanding  on the books of the Fund for specified
periods.

         The Principal Underwriter intends, but is not obligated, to continue to
pay or accrue  distribution  charges  incurred  in  connection  with the Class B
Distribution  Plans that exceed current annual payments permitted to be received
by the Principal Underwriter from the Fund. The Principal Underwriter intends to
seek full payment of such charges from the Fund (together  with annual  interest
thereon at the prime rate plus one  percent)  at such time in the future as, and
to the extent that,  payment  thereof by the Fund would be within the  permitted
limits.

         If the FUND's Independent Trustees authorize such payments,  the effect
would be to extend the period of time  during  which the Fund incurs the maximum
amount  of  costs  allowed  by  a  Class  B  Distribution  Plan.  If a  Class  B
Distribution  Plan  is  terminated,  the  Principal  Underwriter  will  ask  the
Independent  Trustees to take whatever  action they deem  appropriate  under the
circumstances with respect to payment of such amounts.

         In  connection  with  financing  its  distribution   costs,   including
commission advances to dealers and others, the Principal Underwriter has sold to
a financial institution substantially all of its 12b-1 fee collection rights and
contingent  deferred sales charge collection rights in respect of Class B shares
sold during the two-year period commencing  approximately June 1, 1995. The FUND
has  agreed  not to reduce  the rate of payment of 12b-1 fees in respect of such
Class B shares unless it terminated such shares'  Distribution  Plan completely.
If it terminated  such  Distribution  Plan,  the FUND may be subject to possible
adverse distribution consequences.

CLASS C DISTRIBUTION PLAN

         The Class C  Distribution  Plan provides that the Fund may expend daily
amounts at an annual rate of up to 1.00% of the Fund's  average  daily net asset
value  attributable  to Class C shares to finance any activity that is primarily
intended to result in the sale of Class C shares, including, without limitation,
expenditures  consisting  of payments to the principal  underwriter  of the Fund
(currently the Principal Underwriter) to enable the Principal Underwriter to pay
to  others  (dealers)  commissions  in  respect  of  Class C shares  sold  since
inception of the Distribution Plan; and (2) to enable the Principal  Underwriter
to pay or to have  paid to  others  a  service  fee,  at such  intervals  as the
Principal Underwriter may determine,  in respect of Class C shares maintained by
any such recipients outstanding on the books of the Fund for specified periods.

         The  Principal  Underwriter  generally  reallows to brokers or others a
commission  in the amount of 0.75% of the price paid for each Class C share sold
plus the first year's service fee in advance in the amount of 0.25% of the price
paid for each Class C share sold. Beginning  approximately  fifteen months after
purchase,  brokers or others  receive a  commission  at an annual  rate of 0.75%
(subject  to NASD rules)  plus  service  fees at the annual rate of 0.25% of the
average daily net asset value of each Class C share maintained by the recipients
outstanding on the books of the Fund for specified periods.

DISTRIBUTION PLANS - GENERAL

         Each of the Distribution Plans may be terminated at any time by vote of
the Rule 12b-1  Trustees  or by a vote of a majority of the  outstanding  voting
shares of the respective Class. For the Florida Fund, the Pennsylvania Fund, the
Texas Fund, the  Massachusetts  Fund and the New York Insured Fund  unreimbursed
Class B Distribution  Plan expenses at March 31, 1995 were $3,196,058  (6.12% of
net assets),  $1,923,455 (6.27% of net assets),  $145,495 (6.73% of net assets),
$384,672 (6.24% of net assets) and $728,940 (6.26% of net assets), respectively.

         Any change in a Distribution  Plan that would  materially  increase the
distribution  expenses of the affected Fund provided for in a Distribution  Plan
requires the Fund's shareholders'  approval.  Otherwise,  the Distribution Plans
may be amended by the Trustees, including the Rule 12b-1 Trustees.

         While the Distribution  Plans are in effect,  the FUND will be required
to commit the selection and nomination of candidates for Independent Trustees to
the discretion of the Independent Trustees.

         The total amounts paid by a Fund under the foregoing  arrangements  may
not exceed the maximum  Distribution Plan limit specified above, and the amounts
and purposes of expenditures  under a Distribution  Plan must be reported to the
Rule 12b-1  Trustees  quarterly.  The Rule 12b-1 Trustees may require or approve
changes in the  implementation  or operation of a Distribution Plan and may also
require  that total  expenditures  by a Fund under a  Distribution  Plan be kept
within limits lower than the maximum amount permitted by a Distribution  Plan as
stated above.

         During  the  fiscal  year  ended  March 31,  1995,  the  Florida  Fund,
Pennsylvania Fund, Texas Fund,  Massachusetts Fund and the New York Insured Fund
paid the Principal Underwriter (1) $66,246,  $44,697, $2,847, $1,829 and $3,025,
respectively,  pursuant to each Fund's Class A Distribution  Plan; (2) $345,221,
$244,404,  $18,613, $40,387 and $70,227,  respectively,  pursuant to each Fund's
Class B  Distribution  Plan; and (3) $140,405,  $81,781,  $5,377,  $15,014,  and
$15,895, respectively, pursuant to each Fund's Class C Distribution Plan.

         The Independent  Trustees of the FUND have determined that the sales of
each Fund's shares  resulting  from  payments  under its  Distribution  Plan are
expected to benefit such Fund.

02116-5034,   has  provided  investment  advisory  and  management  services  to
investment  companies  and  private  accounts  since it was  organized  in 1932.
Keystone is a  wholly-owned  subsidiary  of Keystone  Investments,  200 Berkeley
Street, Boston, Massachusetts 02116-5034.

         Keystone  Investments is a corporation  predominantly  owned by current
and former members of Keystone's  management and its  affiliates.  The shares of
Keystone  Investments  common  stock  beneficially  owned by current  and former
members of  management  are held in a number of voting  trusts,  the trustees of

personnel and general corporate services to Keystone Management, Keystone, their
affiliates and the Keystone Investments Family of Funds.

         Pursuant to the Investment  Advisory and Management  Agreement with the
FUND  dated  August  19,  1993 (the  "Advisory  Agreement")  and  subject to the
supervision of the FUND's Board of Trustees,  Keystone  manages and  administers
the  operation  of the  FUND and its  Funds,  and  manages  the  investment  and

objectives and  restrictions.  The Advisory  Agreement  stipulates that Keystone
shall provide  office  space,  all necessary  office  facilities,  equipment and
personnel in  connection  with its services as well as pay or reimburse the FUND
for the  compensation  of FUND officers and Trustees who are affiliated with the
investment  adviser.  The Advisory Agreement requires Keystone to pay all of its

Management                                                          Value of the
Fee                                                           Shares of the Fund
- --------------------------------------------------------------------------------
0.55%             of the first                               $  50,000,000, plus
0.50%             of the next                                $  50,000,000, plus
0.45%             of the next                                $ 100,000,000, plus
0.40%             of the next                                $ 100,000,000, plus
0.35%             of the next                                $ 100,000,000, plus
0.30%             of the next                                $ 100,000,000, plus
0.25%             of amounts over                            $ 500,000,000

         Computed as of the close of business each business day and paid daily.

         The  Advisory  Agreement  continues in effect from year to year only if
approved  at least  annually  by the FUND's  Board of Trustees or by a vote of a
majority  of the  outstanding  shares of each Fund,  and such  renewal  has been
approved by the vote of a majority of the Independent Trustees cast in person at
a meeting  called  for the  purpose  of voting on such  approval.  The  Advisory
Agreement may be terminated,  without penalty, on 60 days' written notice by the
FUND's  Board of Trustees or by a vote of a majority  of  outstanding  shares of
each  Fund.  The  Advisory  Agreement  will  terminate  automatically  upon  its
"assignment" as that term is defined in the 1940 Act.

         During  the  year  ended  March  31,  1993,  the  Florida  Fund and the
Pennsylvania  Fund  paid  or  accrued  to  Keystone  investment  management  and
administrative services fees of $199,288 and $138,570, respectively.  During the
period  ended  March 31,  1993,  the  Texas  Fund paid or  accrued  to  Keystone
investment management and administrative services fees of $8,092.

         During  the  year  ended  March  31,  1994,   the  Florida  Fund,   the
Pennsylvania  Fund,  and the Texas Fund paid or accrued to  Keystone  investment
management and administrative services fees of $363,939,  $291,982, and $22,246,
respectively.  During the period ended March 31, 1994, the Massachusetts and the
New York  Insured  Fund paid or accrued to Keystone  investment  management  and
service fees of $2,167 and $1,473, respectively.

         During  the  year  ended  March  31,  1995,   the  Florida  Fund,   the
Pennsylvania  Fund and the Texas  Fund paid or accrued  to  Keystone  investment
management and administrative  services fees of $515,205,  $357,852 and $25,402,
respectively.  During the year ended March 31, 1995, the Massachusetts  Fund and
the New York Insured Fund paid or accrued to Keystone investment  management and
administrative services fees of $43,636 and $63,808, respectively.

         Until December 31, 1995,  Keystone has voluntarily  agreed to limit the
expenses  of the FUND's  Class A, B and C shares to 0.75%,  1.50%,  and 1.50% of
average daily net assets, respectively. Thereafter, a redetermination of whether
to  continue  these  expense  limitations  will be made.  Keystone  would not be
required to make such reimbursement to any Fund to the extent it would result in
the Fund's  inability  to qualify as a regulated  investment  company  under the
Code. In accordance  with  voluntary  expense  limitations  in effect during the
fiscal year ended March 31, 1994,  Keystone  reimbursed  the Florida  Fund,  the
Pennsylvania  Fund,  the Texas  Fund,  the  Massachusetts  Fund and the New York
Insured Fund (1) $89,179,  $91,489,  $35,517,  $26,169 and $22,366 respectively,

respect to each Fund's Class C shares.

- --------------------------------------------------------------------------------
                               PRINCIPAL UNDERWRITER
- --------------------------------------------------------------------------------

         The FUND has  entered  into a  Principal  Underwriting  Agreement  (the
"Underwriting  Agreement") dated August 19, 1993 with the Principal Underwriter,
a wholly-owned subsidiary of Keystone. The Principal Underwriter,  as agent, has
agreed to use its best efforts to find purchasers for the shares.  The Principal
Underwriter may retain and employ representatives to promote distribution of the
shares and may  obtain  orders  from  brokers,  dealers  and  others,  acting as
principals,  for sales of shares to them. The  Underwriting  Agreement  provides
that the Principal Underwriter will bear the expense of preparing,  printing and
distributing  advertising and sales literature and  prospectuses  used by it. In
its capacity as principal  underwriter,  the Principal  Underwriter  may receive
payments from each Fund pursuant to such Fund's Distribution Plan.

         All subscriptions and sales of shares by the Principal  Underwriter are
at the offering  price of the shares in  accordance  with the  provisions of the
FUND's  Declaration of Trust,  By-Laws,  the current prospectus and statement of
additional information. All orders are subject to acceptance by the FUND and the
FUND  reserves the right in its sole  discretion  to reject any order  received.
Under the Underwriting  Agreement,  the FUND is not liable to anyone for failure
to accept any order.

         The  FUND  has  agreed  under  the  Underwriting  Agreement  to pay all
expenses in  connection  with  registration  of the shares of its Funds with the
Commission as well as auditing and filing fees in connection  with  registration
of such shares  under the  various  state  "blue-sky"  laws,  and the  Principal
Underwriter assumes the cost of sales literature and preparation of prospectuses
used by it and certain other expenses.

         From time to time, if in the Principal  Underwriter's judgment it could
benefit the sales of a Fund's  shares,  the  Principal  Underwriter  may use its
discretion in providing to selected  dealers  promotional  materials and selling
aids,  including,  but not limited to, personal computers,  related software and
Fund data files.

         The Principal  Underwriter has agreed that it will in all respects duly
conform with all state and federal laws applicable to the sale of the shares and
will  indemnify and hold harmless the FUND,  and each person who has been, is or
may be a Trustee or officer of the FUND, against expenses reasonably incurred by
any of them in connection with any claim, or in connection with any action, suit
or  proceeding  to which any of them may be a party,  which  arises out of or is
alleged to arise out of any  misrepresentation  or  omission to state a material
fact on the part of the Principal Underwriter or any other person for whose acts
the Principal Underwriter is responsible or is alleged to be responsible, unless
such misrepresentation or omission was made in reliance upon written information
furnished by the FUND.

         The  Underwriting  Agreement  provides that it will remain in effect as
long as its terms and  continuance are approved by a majority of the FUND's Rule
12b-1 Trustees at least annually at a meeting called for that purpose and if its
continuance  is  approved  annually  by vote of a  majority  of the  Rule  12b-1
Trustees  or by vote of a majority  of the  outstanding  shares of the  affected
Funds.

         The Underwriting  Agreement may be terminated,  without penalty,  on 60
days'  written  notice  by the  FUND's  Rule  12b-1  Trustees  or the  Principal
Underwriter  or terminated as to any Fund by a vote of a majority of outstanding
shares of such Fund. The  Underwriting  Agreement  will terminate  automatically
upon its "assignment" as that term is defined in the 1940 Act.

- --------------------------------------------------------------------------------
                                  BROKERAGE
- --------------------------------------------------------------------------------

         It is the policy of the FUND,  in effecting  transactions  in portfolio
securities,  to seek best execution of orders at the most favorable prices.  The
determination  of what may constitute  best execution and price in the execution
of a securities  transaction  by a broker  involves a number of  considerations,
including, without limitation, the overall direct net economic result to a Fund,
involving both price paid or received and any  commissions and other costs paid,
the efficiency with which the transaction is effected, the ability to effect the
transaction  at all where a large block is  involved,  the  availability  of the
broker to stand  ready to  execute  potentially  difficult  transactions  in the
future and the financial strength and stability of the broker. Management weighs
such  considerations  in  determining  the overall  reasonableness  of brokerage
commissions paid.

         Subject to the  foregoing,  a factor in the selection of brokers is the
receipt of research services,  such as analyses and reports concerning  issuers,
industries,  securities,  economic factors and trends and other  statistical and
factual  information.  Any such  research  and  other  statistical  and  factual
information provided by brokers to a Fund is considered to be in addition to and
not in lieu of services  required to be performed by Keystone under its Advisory
Agreement  with the FUND.  The  cost,  value and  specific  application  of such
information  are  indeterminable  and cannot be practically  allocated among the
Funds  and  other  clients  of  Keystone  who may  indirectly  benefit  from the
availability of such information.  Similarly, a Fund may indirectly benefit from
information  made available as a result of transactions  effected for such other
clients.  Under the  Advisory  Agreement,  Keystone is  permitted  to pay higher
brokerage  commissions  for brokerage and research  services in accordance  with
Section 28(e) of the Securities Exchange Act of 1934. In the event Keystone does
follow such a practice,  it will do so on a basis that is fair and  equitable to
the Funds.

         The FUND expects that purchases and sales of municipal  obligations and
temporary  instruments  usually  will  be  principal   transactions.   Municipal
obligations and temporary  instruments are normally  purchased directly from the
issuer or from an underwriter or market maker for the securities.  There usually
will be no brokerage  commissions  paid by a Fund for such purchases.  Purchases
from  underwriters will include the underwriting  commission or concession,  and
purchases from dealers  serving as market makers will include a dealer's mark up
or  reflect  a  dealer's  mark  down.   Where   transactions  are  made  in  the
over-the-counter  market,  each Fund will deal with primary market makers unless
more favorable prices are otherwise obtainable.

         Each Fund may participate,  if and when  practicable,  in group bidding
for the purchase  directly from an issuer of certain  securities  for the Fund's
portfolio in order to take advantage of the lower  purchase  price  available to
members of such a group.

         Neither Keystone nor the Funds intend to place securities  transactions
with any particular broker-dealer or group thereof. The FUND's Board of Trustees
has determined, however, that the Funds may follow a policy of considering sales
of shares as a factor in the selection of  broker-dealers  to execute  portfolio
transactions,  subject to the  requirements  of best  execution,  including best
price, described above.

         The  policy  of the  FUND  with  respect  to  brokerage  is and will be
reviewed  by the  FUND's  Board of  Trustees  from time to time.  Because of the
possibility  of  further  regulatory   developments   affecting  the  securities
exchanges  and brokerage  practices  generally,  the foregoing  practices may be
changed, modified or eliminated.

         Investment  decisions for the Funds are made  independently by Keystone
from those of the other funds and investment  accounts  managed by Keystone.  It
may frequently  develop that the same investment  decision is made for more than
one fund.  Simultaneous  transactions  are inevitable  when the same security is
suitable for the investment objective of more than one account. When two or more
funds or accounts are engaged in the purchase or sale of the same security,  the
transactions  are allocated as to amount in  accordance  with a formula which is
equitable  to each fund or  account.  It is  recognized  that in some cases this
system could have a detrimental effect on the price or volume of the security as
far as the Funds are concerned. In other cases, however, it is believed that the
ability of a Fund to  participate  in volume  transactions  will produce  better
executions for the Fund.

         For the fiscal  years and/or  periods,  as the case may be, ended March
31, 1993, March 31, 1994 and March 31, 1995, the
Funds did not pay any brokerage commissions.

         In no  instance  are  portfolio  securities  purchased  from or sold to
Keystone,  the Principal  Underwriter  or any of their  affiliated  persons,  as
defined in the 1940 Act and rules and regulations issued thereunder.

- --------------------------------------------------------------------------------
                              DECLARATION OF TRUST
- --------------------------------------------------------------------------------

MASSACHUSETTS BUSINESS TRUST

         The  FUND  is  a  Massachusetts  business  trust  established  under  a
Declaration of Trust dated September 13, 1990 ("Declaration of Trust"). The FUND
is similar in most respects to a business corporation. The principal distinction
between  the  FUND  and a  corporation  relates  to  the  shareholder  liability
described  below.  A copy of the  Declaration of Trust is filed as an exhibit to
the FUND's Registration Statement.  This summary is qualified in its entirety by
reference to the Declaration of Trust.

DESCRIPTION OF SHARES

         The Declaration of Trust authorizes the issuance of an unlimited number
of shares of  beneficial  interest  of classes  of shares.  Each share of a Fund
represents an equal proportionate interest in such Fund with each other share of
the Fund. Generally, each Fund currently issues three classes of shares, but may
issue additional classes or series of shares. Upon liquidation,  Fund shares are
entitled  to a pro rata  share of the Fund based on the  relative  net assets of
each class.  Shareholders  have no preemptive or conversion  rights.  Shares are
transferable,  redeemable  and  fully  assignable  as  collateral.  There are no
sinking fund provisions.

SHAREHOLDER LIABILITY

         Pursuant  to  certain  decisions  of  the  Supreme  Judicial  Court  of
Massachusetts, shareholders of a Massachusetts business trust may, under certain
circumstances,  be held personally liable as partners for the obligations of the
trust.  If the  FUND  were  held to be a  partnership,  the  possibility  of the
shareholders incurring financial loss for that reason appears remote because the
FUND's  Declaration  of Trust (1) contains an express  disclaimer of shareholder
liability  for  obligations  of the  FUND;  (2)  requires  that  notice  of such
disclaimer be given in each agreement,  obligation or instrument entered into or
executed by the FUND or the Trustees;  and (3) provides for  indemnification out
of FUND property for any shareholder held personally  liable for the obligations
of the FUND.

VOTING RIGHTS

         Under the Declaration of Trust, the FUND does not hold annual meetings.
Shares of a Fund are  entitled  to one vote per  share.  Shares  generally  vote
together as one class on all matters, except that each Fund has exclusive voting
rights with respect to matters which affect only that Fund. Classes of shares of
a Fund have equal voting  rights  except that each class of shares has exclusive
voting rights with respect to its respective Distribution Plan. No amendment may
be made to the  Declaration of Trust that adversely  affects any class of shares
without the  approval  of a majority  of the shares of that  class.  Shares have
non-cumulative  voting rights,  which means that the holders of more than 50% of
the shares voting for the election of Trustees can elect 100% of the Trustees to
be elected at a meeting and, in such event,  the holders of the remaining 50% or
less of the shares voting will not be able to elect any Trustees.

         After the  initial  meeting to elect  Trustees  no further  meetings of
shareholders for the purpose of electing  Trustees will be held, unless required
by law,  until such time as less than a majority of the Trustees  holding office
have been elected by  shareholders,  at which time the  Trustees  then in office
will call a shareholders' meeting for election of Trustees.

         Except as set forth above,  the Trustees  shall continue to hold office
indefinitely,  unless  otherwise  required  by law,  and may  appoint  successor
Trustees. A Trustee may be removed from or cease to hold office (as the case may
be) (1) at any time by two-thirds vote of the remaining Trustees;  (2) when such
Trustee  becomes  mentally  or  physically  incapacitated;  or (3) at a  special
meeting of  shareholders by a two-thirds  vote of the  outstanding  shares.  Any
Trustee may voluntarily resign from office.

LIMITATION OF TRUSTEES' LIABILITY

         The  Declaration  of Trust provides that a Trustee shall be liable only
for his own willful  defaults and, if reasonable  care has been exercised in the
selection of officers,  agents,  employees or investment advisers,  shall not be
liable for any neglect or wrongdoing of any such person; provided, however, that
nothing  in the  Declaration  of Trust  shall  protect  a  Trustee  against  any
liability for his willful  misfeasance,  bad faith, gross negligence or reckless
disregard of his duties.

         The Trustees have absolute and  exclusive  control over the  management
and disposition of all assets of the Funds and may perform such acts as in their
sole  judgment  and  discretion  are  necessary  and proper for  conducting  the
business and affairs of the FUND or promoting  the interests of the FUND and its
Funds and the shareholders.

- --------------------------------------------------------------------------------
                   STANDARDIZED TOTAL RETURN AND YIELD QUOTATIONS
- --------------------------------------------------------------------------------

         Total  return  quotations  for a class of  shares of a Fund as they may
appear from time to time in advertisements are calculated by finding the average
annual compounded rates of return over one, three, five and ten year periods, or
the time periods for which such class of shares has been effective, whichever is
relevant,  on a  hypothetical  $1,000  investment  that would equate the initial
amount  invested  in the class to the ending  redeemable  value.  To the initial
investment  all dividends and  distributions  are added,  and all recurring fees
charged to all shareholder  accounts are deducted.  The ending  redeemable value
assumes a complete redemption at the end of the relevant periods.

respectively.

CURRENT YIELD AND TAX EQUIVALENT YIELD

         Current  yield  quotations  as they  may  appear  from  time to time in
advertisements  will  consist of a quotation  based on a 30- day period ended on
the date of the most recent  balance  sheet of a Fund,  computed by dividing the
net investment income per share earned during the period by the maximum offering
price per share on the last day of the base  period.  Such  yield  will  include
income from sources other than municipal obligations, if any.

         For the 30-day period ended March 31, 1995,  the current yield of Class
A of the Florida Fund, the Pennsylvania  Fund, the Texas Fund, the Massachusetts
Fund and the New York Insured  Fund was 5.37%,  5.33%,  5.32%,  5.61% and 5.15%,

         Tax  equivalent  yield is, in general,  the current  yield divided by a
factor  equal to one minus a stated  income  tax rate and  reflects  the yield a
taxable investment would have to achieve in order to equal on an after-tax basis
a tax-exempt yield.

         The tax equivalent yield for the 30-day period ended March 31, 1995 for
Class A of the  Florida  Fund,  the  Pennsylvania  Fund,  the  Texas  Fund,  the
Massachusetts Fund and the New York Insured Fund was 7.78%,  7.72%, 7.71%, 8.13%
and 7.46%, respectively.

         The tax equivalent yield for the 30-day period ended March 31, 1995 for
Class B of the  Florida  Fund,  the  Pennsylvania  Fund,  the  Texas  Fund,  the
Massachusetts Fund and the New York Insured Fund was 7.09%,  7.03%, 7.01%, 7.43%
and 6.74%, respectively.

         The tax equivalent yield for the 30-day period ended March 31, 1995 for
Class C of the  Florida  Fund,  the  Pennsylvania  Fund,  the  Texas  Fund,  the
Massachusetts Fund and the New York Insured Fund was 7.09%,  7.03%, 7.00%, 7.45%

                         KEYSTONE FLORIDA TAX FREE FUND

REVENUES

     The  State  accounts  for  its  receipts  using  fund  accounting.  It  has
established the General Revenue Fund, the Working Capital Fund and various other
trust funds,  which are  maintained for the receipt of monies which under law or
trust agreements must be maintained separately.

   
     The General  Revenue Fund consists of all monies received by the State from
every  source  whatsoever  which are not  allocable  to the other  funds.  Major
sources of tax revenues for the General  Revenue Fund are the sales and use tax,
the corporate  income tax, and the intangible  personal  property tax, which are
projected for fiscal year 1995-96 to amount to 71%, 8% and 4%, respectively,  of
the total receipts of that fund.
    

     The Florida  Constitution and its statutes mandate that the State budget as
a whole and each  separate  fund within the State budget be kept in balance from
currently available revenues for each fiscal year.

SALES AND USE TAX

   
     The greatest  single source of tax receipts in Florida is the sales and use
tax,  which is  projected  to amount to 10.3  billion  dollars  for fiscal  year
1995-96.  The sales tax is 6% of the sales price of tangible  personal  property
sold at retail in the state.  The use tax is 6% of the cash price or fair market
value of tangible  personal  property when it is not sold but is used, or stored
for  use,  in the  State.  In other  words,  the use tax  applies  to the use of
tangible personal property in Florida,  which was purchased in another state but
would have been subject to the sales tax if purchased in Florida.  Approximately
10% of the sales tax is designated for local  governments  and is distributed to
the  respective  counties  in  which  collected  for  use by such  counties  and
municipalities therein. In addition to this distribution,  local governments may
(by referendum) assess a 1% sales surtax within their county. Proceeds from this
local option sales surtax can be earmarked for funding  countywide bus and rapid
transit systems, local infrastructure construction and maintenance,  and medical
care for indigents, as set forth in Section 212.055(2), of the Florida Statutes.
    

     The two taxes, sales and use, stand as complements to each other, and taken
together  provide a uniform tax upon either the sale at retail or the use of all
tangible personal property irrespective of where it may have been purchased. The
sales  tax also  includes  a levy on the  following:  (i)  rentals  on  tangible
personal  property  and  accommodations  in  hotels,  motels,  some  apartments,
offices,  real estate,  parking and storage places in parking lots,  garages and
marinas for motor  vehicles or boats;  (ii)  admissions to places of amusements,
most sports and recreation events; (iii) utilities,  except those used in homes;
and  (iv)  restaurant  meals  and  expendables  used  in  radio  and  television
broadcasting.  Exemptions  include:  groceries;  medicines;  hospital  rooms and
meals; seeds, feeds,  fertilizers and farm crop protection materials;  purchases
by religious,  charitable and educational nonprofit  institutions;  professional
services,  insurance  and certain  personal  service  transactions;  newspapers;
apartments  used as permanent  dwellings;  and  kindergarten  through  community
college athletic contests or amateur plays.

OTHER STATE TAXES

     Other  taxes which  Florida  levies  include the motor fuel tax,  corporate
income tax,  intangible  property tax,  documentary  stamp tax,  gross  receipts
utilities tax and severance tax on the  production of oil and gas and the mining
of solid minerals, such as phosphate and sulfur.

LOCAL GOVERNMENT DEBT

     Numerous government units,  counties,  cities, school districts and special
taxing districts,  issue general  obligation bonds backed by their taxing power.
State  and local  government  units may  issue  revenue  obligations,  which are
supported by the revenues generated from the particular projects or enterprises.
Examples  include  obligations  issued to finance the  construction of water and
sewer systems, health care facilities and educational facilities. In some cases,
sewer or water revenue obligations may be additionally secured by the full faith
and credit of the State.

OTHER FACTORS

     The performance of the obligations issued by Florida,  its  municipalities,
subdivisions and instrumentalities are in part tied to state-wide,  regional and
local  conditions  within Florida.  Adverse  changes to state-wide,  regional or
local  economies  may  adversely  affect the  creditworthiness  of Florida,  its
municipalities,  etc. Also,  some revenue  obligations  may be issued to finance
construction of capital projects which are leased to  nongovernmental  entities.
Adverse  economic  conditions  might affect those lessees' ability to meet their
obligations  to the  respective  governmental  authority  which  in  turn  might
jeopardize  the  repayment of the  principal of, or the interest on, the revenue
obligations.


                      KEYSTONE MASSACHUSETTS TAX FREE FUND

GENERAL

     The  Commonwealth's  constitution  requires,  in effect,  that its  budget,
though not necessarily its operating  expenditures and revenue, be balanced each
year. In addition,  the Commonwealth has certain budgetary procedures and fiscal
controls in place that are designed to ensure that  sufficient cash is available
to meet the Commonwealth's  obligations,  that state expenditures are consistent
with  periodic  allotments  of  annual  appropriations  and that the  funds  are
expended  consistent  with  statutory and public  purposes.  The General Fund is
generally  regarded as the  principal  indicator  of whether the  Commonwealth's
operating  revenues and expenses are in balance.  The other principal  operating
funds (the Local Aid Fund and the  Highway  Fund) are  customarily  funded to at
least a zero balance.

     Although the Commonwealth experienced quite a slowdown during the recession
with  spending  exceeding  revenues,  beginning  in 1991  the  Commonwealth  has
experienced a turn-around  in its finances  with  revenues  exceeding  spending.
Budgeted  expenditures for fiscal 1989, 1990 and 1991 were approximately $12.643
billion,  $13.260  billion  and $13.659  billion,  respectively  while  budgeted
revenues and other sources for those years were approximately  $11.970,  $12.008
billion and $13.634 billion, respectively. By comparison,  budgeted revenues and
other sources  increased by approximately  0.7% from fiscal 1991 to fiscal 1992,
while tax revenues increased by 5.4% for the same period.  Budgeted expenditures
in  fiscal  1992  were  1.7%  lower  than  fiscal  1991  budgeted  expenditures.
Furthermore,  total  revenues  and  other  sources  for  fiscal  1993  increased
approximately  6.9% from fiscal 1992,  while tax revenues  increased by 4.7% for
the same  period.  Budgeted  expenditures  and other  uses in  fiscal  1993 were
approximately  9.6% higher than fiscal 1992  expenditures  and other uses. As of
1993  fiscal  year  end,  the  Commonwealth  showed a year-end cash  position of
approximately  $622.2  million,  as compared  to a projected  position of $485.1
million.  By comparison,  the Commonwealth  ended the 1989 fiscal year with fund
balances in deficit by $319.3 million.

     The fiscal  1994  budget,  as signed  into law by the  Governor on July 19,
1993, provides for expenditures of approximately $15.500 billion, an increase of
5.5% over fiscal 1993 levels. Budgeted revenues for fiscal 1994 are estimated to
be  approximately  $15.483  billion,  which  is 5.3%  higher  than  fiscal  1993
expenditures.  This amount  includes  estimated  tax  revenues of  approximately
$10.560 billion,  which is 6.3% higher than fiscal 1993 tax revenues. For fiscal
1994, a combined balance of $541.4 million is expected in the  stabilization and
undesignated  general  funds.  The fiscal  1994  budget is based  upon  numerous
spending and revenue estimates, the achievement of which cannot be assured.

     In June 1993, new comprehensive  education reform  legislation was enacted.
It  is  expected  that  this   legislation  will  require  annual  increases  in
expenditures  for education  purposes  above fiscal 1993 base spending of $1.289
billion of  approximately  $175 million in fiscal  1994,  $141 million in fiscal
1995 and $662  million in fiscal  1996.  The fiscal  1994 budget  includes  $175
million  in  appropriations  to satisfy  this  legislation.  Municipalities  and
agencies  of the  Commonwealth  are  experiencing  the  same  economic  effects.
Moreover,  they are affected by the  financial  condition  of the  Commonwealth,
because they receive substantial funding from the Commonwealth.

LIMITATIONS ON TAX REVENUES

     In Massachusetts,  efforts to limit and reduce levels of taxation have been
underway for several  years.  Limits were  established  on state tax revenues by
legislation  enacted on October 25, 1986 and by an initiative  petition approved
by the voters on November 4, 1986. The two measures are  inconsistent in several
respects.

     Chapter 62F, which was added to the General Laws by initiative  petition in
November 1986, establishes a state tax revenue growth limit for each fiscal year
equal to the average  positive rate of growth in total wages and salaries in the
Commonwealth,  as reported by the federal government,  during the three calendar
years  immediately  preceding  the end of such  fiscal  year.  Chapter  62F also
requires that  allowable  state tax revenues be reduced by the aggregate  amount
received by local  governmental  units from any newly  authorized  or  increased
local option taxes or excises. Any excess in state tax revenue collections for a
given fiscal year over the prescribed limit, as determined by the State Auditor,
is to be  applied  as a credit  against  the then  current  personal  income tax
liability of all  taxpayers in the  Commonwealth  in  proportion to the personal
income tax liability of all taxpayers in the  Commonwealth  for the  immediately
preceding tax year. The legislation enacted in October 1986, which added Chapter
29B to the General Laws,  also  establishes  an allowable  state revenue  growth
factor by reference to total wages and  salaries in the  Commonwealth.  However,
rather than utilizing a three-year  average wage and salary growth rate, as used
by Chapter 62F,  Chapter 29B utilizes an allowable  state revenue  growth factor
equal to 1/3 o the positive  percentage gain in Massachusetts wages and salaries
during the three calendar years immediately  preceding the end of a given fiscal
year.

     Tax revenues in fiscal 1989  through  fiscal 1993 were lower than the limit
set  by  either   Chapter  62F  or  Chapter  29B.  The   Executive   Office  for
Administration and Finance currently estimates that state tax revenues in fiscal
1994 will not reach the limit imposed by either of these statutes.

     In January 1992, the Governor  announced his intention to seek an amendment
to the state  constitution  that would require any  Commonwealth tax increase to
receive at least a two-thirds majority vote in each house of the Legislature. No
action has yet been taken on this proposal.

PROPOSITION 2 1/2

     In November  1980,  voters in the  Commonwealth  approved a  statewide  tax
limitation  initiative  petition,  commonly  known  as  Proposition  2  1/2,  to
constrain levels of property  taxation and to limit the charges and fees imposed
on  cities  and  towns  by  certain  governmental  entities,   including  county
governments.  Proposition 2 1/2 is not a provision of the state constitution and
accordingly is subject to amendment or repeal by the legislature.  Proposition 2
1/2,  as amended to date,  limits the  property  taxes that may be levied by any
city or town in any  fiscal  year to the lesser of (i) 2.5% of the full and fair
cash valuation of the real estate and personal property  therein,  and (ii) 2.5%
over the previous year's levy limit plus any growth in the tax base from certain
new  construction  and parcel  subdivisions.  Proposition  2 1/2 also limits any
increase  in the charges and fees  assessed  by certain  governmental  entities,
including county governments,  on cities and towns to the sum of (i) 2.5% of the
total  charges  and fees  imposed in the  preceding  fiscal  year,  and (ii) any
increase  in charges  for  services  customarily  provided  locally or  services
obtained by the city or town at its option.

     Many communities have responded to the limitations imposed by Proposition 2
1/2 through statutorily  permitted  overrides and exclusions.  Override activity
peaked in fiscal 1991, when 182 communities  attempted votes on one of the three
types of referenda questions (override of levy limit, exclusion of debt service,
or  exclusion  of capital  expenditures)  and 100 passed at least one  question,
adding $58.5 million to their levy limits. In fiscal 1992, 67 of 143 communities
had successful  votes  totalling  $31.0 million.  In fiscal 1993, 83 communities
attempted a vote;  two-thirds of them (56) passed  questions  aggregating  $16.4
million.  Although  Proposition 2 1/2 will continue to constrain  local property
tax revenues, significant capacity exists for overrides in every community.

LOCAL AID

     During the  1980's,  the  Commonwealth  increased  payments  to its cities,
towns,  and regional  school  districts  ("Local Aid") to mitigate the impact of
Proposition 2 1/2 on local programs and services. In fiscal 1994,  approximately
28.7% of the  Commonwealth's  budget is  estimated to be allocated to Local Aid.
Local Aid payments to cities, towns, and regional school districts take the form
of both direct and indirect assistance.

     Direct  local aid  decreased  from $2.961  billion in fiscal 1989 to $2.328
billion in fiscal 1992 and  increased to $2.547  billion in fiscal  1993.  It is
estimated  that fiscal  1994  expenditures  for direct  Local Aid will be $2.737
billion, which is an increase of approximately 7.5% above the fiscal 1993 level.
The additional amount of indirect Local Aid provided over and above direct Local
Aid was  approximately  $1.717  billion in fiscal 1993. It is estimated  that in
fiscal 1994  approximately  $1.717  billion of  indirect  Local Aid will also be
paid.

     A  statute  adopted  by voter  initiative  petition  at the  November  1990
statewide  election regulates the distribution of Local Aid to cities and towns,
by requiring,  subject to  appropriation,  that no less than 40% of  collections
from personal income taxes,  sales and use taxes,  corporate  excise taxes,  and
lottery fund  proceeds be  distributed  to cities and towns.  Under the law, the
Local Aid distribution to each city or town would equal no less than 100% of the
total Local Aid received for fiscal 1989. Distributions in excess of fiscal 1989
levels would be based on new formulas.  By its terms, the new formula would have
called for a substantial  increase in direct Local Aid in fiscal 1992, and would
call for such an increase in fiscal 1993 and subsequent  years.  However,  Local
Aid payments expressly remain subject to annual  appropriation,  and fiscal 1992
and fiscal  1993  appropriations  for Local Aid did not meet,  and  fiscal  1994
appropriations for Local Aid do not meet, the levels set forth in the initiative
law.

COMMONWEALTH EXPENDITURES

     From  fiscal  1989  to  fiscal  1991,  total  program  expenditures  of the
Commonwealth  (which  excludes  interfund  transfers) in its budgeted  operating
funds  increased at an average annual rate of  approximately  4.0%.  Fiscal 1992
program  expenditures  were  $13.420  billion,  or 1.7% lower  than 1992  fiscal
program expenditures.

     For fiscal 1993, program expenditures were $14.696 billion,  representing a
9.6%  increase  from fiscal  1992.  It is  estimated  that  fiscal 1994  program
expenditures  will total $15.500  billion,  an increase of 5.5% over fiscal 1993
levels.

     Commonwealth  expenditures  since fiscal 1989 largely  reflect  significant
growth  in  several  programs  and  services   provided  by  the   Commonwealth,
principally Local Aid,  Medicaid and group health  insurance,  public assistance
programs,  debt  service,  pensions,  higher  education  and  assistance  to the
Massachusetts Bay Transportation Authority and regional transit authorities.

     The  Commonwealth  is responsible  for the payment of pension  benefits for
state employees and for school teachers  throughout the state.  The Commonwealth
is also  responsible for cost of living  increases  payable to local  government
retirees. State pension expenditures have risen dramatically as the Commonwealth
has appropriated  moneys to partially address the unfunded  liabilities that had
accumulated  over  several  decades  of  "pay-as-you-go"  administration  of the
pension systems for which it is responsible. For several years during the 1980s,
the Commonwealth made substantial direct  appropriations to pension reserves, in
addition to paying current benefits. In 1988, the Commonwealth adopted a funding
schedule under which it is required to fund future pension liabilities currently
and to  amortize  the  accumulated  unfunded  liabilities  over 40 years.  Total
pension  expenditures  increased  at an average  annual rate of 7.1% from $659.7
million in fiscal 1989 to $868.2 million in fiscal 1993.  The estimated  pension
expenditures for fiscal 1994 are $951.0 million representing an increase of 9.5%
over fiscal 1993 expenditures.

OTHER FACTORS

     Many factors affect the financial condition of the Commonwealth,  including
many  social,  environmental,  and  economic  conditions,  which are  beyond the
control of the Commonwealth. As with most urban states, the continuation of many
of the Commonwealth's programs,  particularly its human service programs, is, in
significant part,  dependent upon continuing federal  reimbursements  which have
been declining.


                        KEYSTONE NEW YORK TAX FREE FUND

GENERAL

     During the 1980's,  New York's  economy  underperformed  the nation's.  The
State's  economic  performance was reflected in a contracting  economic base and
dwindling  economic  growth that resulted in an erosion of the State's  relative
economic  influence.  A review of the decade's  employment trends indicates that
the State  consistently  lagged the nation in employment  growth. In contrast to
the State's  relative  underperformance,  New York City's economy grew steadily.
Economic  growth was  attributed to a 14.4%  overall  employment  increase.  The
service  sector  increased  3.5% per year and the finance and real estate sector
experienced an annual 2.9% increase. The bull markets of the 1980s gave powerful
economic  impetus  to the  financial  sector.  The  boom in the  finance  sector
aggravated  local  inflationary  pressure.  Between  1980 and  1989  the  City's
consumer  price index  increased  4.6% per year versus a 3.6%  increase  for the
nation  and  overall  wage  rates  climbed  7.1%  per  year,  approximately  3.5
percentage points above the U.S. rate. The 1987 stock market crash was a turning
point in the City's  economic  direction.  The ripple  effect of the  post-crash
layoffs in the finance, insurance and real estate sectors resulted in a stagnant
city economy.

     The New York economy was  severely  impacted by the  recession,  but it has
begun to show signs of recovery.  The recession has been more severe in New York
than in other parts of the nation,  owning to a significant  retrenchment in the
financial services industry, cutbacks in defense spending, and an overbuilt real
estate  market.   More  than  564,000  jobs  were  lost  during  the  recession,
representing 7% of the pre-recession  base. During 1993 employment  continued to
decline but at  diminishing  rates (a 0.3% decline  during  1993),  indicating a
stabilizing  economy.  A modest job growth of approximately  0.8% is anticipated
for 1994.  Through  the year 1988 New York's  employment  growth is  expected to
average  approximately  1.4% per year,  compared  to the 2.3%  annual  expansion
experienced  during  1983-1988.  It is  anticipated  that New York's service and
trade  sectors  will  be the  major  contributors  to  this  growth,  while  the
manufacturing sector is expected to continue to contract. The State's economy is
significantly  affected by New York City's  economy by virtue of New York City's
dominance  in  population  and  economic  activity.  New York City  accounts for
approximately 41% of the State's population and personal income.

     The  revised  1993-1994  State  Financial  Plan  is  based  on an  economic
projection  that New York will  perform  more poorly than the nation as a whole.
Real gross  domestic  product grew  modestly  during  calendar  year 1992 and is
expected to show increased growth in calendar 1993. Many uncertainties  exist in
forecasts  of the State's  economy,  which  could have an adverse  effect on the
State,  and there can be no assurance that the State economy will not experience
worse-than-predicted  results  in  the  1994  fiscal  year,  with  corresponding
material  and  adverse  effects  on the  State's  projections  of  receipts  and
disbursements.

     For fiscal 1993, State financial operations produced a $671 million surplus
on a general fund budget of nearly $31 billion. This surplus followed four years
of operating  deficits.  The accumulated  general fund deficit peaked in 1991 at
$6.2  billion and has since  decreased  to $2.6  billion for fiscal  1993.  Debt
reform is the principal cause for this improvement. Short-term borrowing is only
$850 million for the current fiscal year, the lowest level since 1969. To reduce
borrowing  costs  and  improve  market  access,  the  Governor  is  proposing  a
constitutional  amendment to limit issuance of appropriation bonds and to create
tax-backed debt.

     The State's updated  financial plan estimates that fiscal 1994 will achieve
an  ending  cash  balance  of  approximately  $299  million.  This  larger  than
anticipated  surplus  is  a  result  of a  stabilizing  economy,  improving  tax
collections  and slowing  expenditure  growth.  The 1993 and 1994  budgets  were
enacted  in a timely  manner  and were based on  realistic  economic  forecasts,
conservative  revenue  assumptions and some spending  restraint.  The Governor's
proposed  budget for fiscal 1995  provides for general fund  spending  growth of
4.3%,  use of the  current  year  surplus,  modest tax cuts and a small level of
non-recurring  measures.  The fiscal 1995 budget  relies on modest growth of the
economy and includes growth in personal income withholding and sales and use tax
receipts of 5.3% and 4.1%, respectively.

     Significant  litigation  exists at the State  level of  government.  A suit
filed  by  a  taxpayer  activist   challenges  the   constitutionality   of  the
transportation  financing  plan.  Also, in November  1993,  the Court of Appeals
affirmed a lower court's  decision,  declaring that certain  accounting  changes
made in funding methods of the State  retirement  system were  unconstitutional.
The State may also be liable for significant  payments related to a U.S. Supreme
Court decision involving abandoned property.

STATE FINANCING ACTIVITIES

     For the four fiscal  years prior to fiscal  year 1992,  the State  incurred
operating  deficits in the general  fund.  In fiscal  1993,  the State began the
process  of  financial  reform.   Based  upon  realistic  economic  and  revenue
estimates,  the fiscal year 1993 financial plan exceeded expectations and closed
the year with a general  fund  operating  surplus of $671 million in the General
Fund. The surplus  revenues were  deposited  into a tax refund reserve  account,
which typically had been funded in the  $300-$350 million range.  Overfunding of
this reserve allows some additional fiscal  flexibility which was not present in
recent prior State budgets.

     New York, for the second  consecutive  year,  passed its fiscal 1994 budget
essentially  on time.  The State faced a $3.7 billion budget gap for fiscal year
1994,  as  determined  by  baseline  projections.  The  Governor's  1994  budget
addressed  this gap by reducing  expenditures  by $1.6  billion  and  increasing
revenues  by $2.1  billion.  The  budget  is based  upon  conservative  economic
assumptions,  which fall  below  those  forecasted  by the  leading  independent
forecasters.

     During the past  several  years,  the State has been  forced to borrow on a
seasonal  basis  due to cash  flow  timing  problems.  In June  1990,  the Local
Government  Assistance  Corporation  ("LGAC")  was  formed  as a public  benefit
corporation  for the  purpose  of  issuing  long term  obligations  designed  to
eliminate this need. The  legislation  which created the LGAC specified that the
obligations  will be amortized over no more than 30 years and put a $4.7 billion
cap, net of LGAC proceeds,  on the seasonal borrowing  program.  This cap may be
exceeded in cases where the Governor and the legislature have certified the need
for  additional  borrowing and have devised a method for reducing it back to the
cap no later than the fourth  fiscal year after the limit is  exceeded.  If this
cap were to be exceeded,  it could result in action by the rating agencies which
could  adversely  affect  prices of bonds  held by the Fund.  To date,  LGAC has
issued  its  bonds to  provide  net  proceeds  of  $3.281  billion  and has been
authorized  to issue its bonds to provide net  proceeds  of up to an  additional
$703 million during the State's 1994 fiscal year.

     In April 1993,  legislation  was also  enacted  providing  for  significant
changes in the long term financing  practices of the State and the  Authorities.
The Legislature passed a proposed constitutional amendment that would permit the
State,  without a voter  referendum,  but within a  formula-based  cap, to issue
revenue  bonds,  which would be debt of the State secured  solely by a pledge of
certain State tax receipts  (including  those allocated to State funds dedicated
for transportation  purposes) and not by the full faith and credit of the State.
In addition,  the proposed  amendment  would require that State debt be incurred
only for capital projects  included in a multi-year  capital  financing plan and
would prohibit  lease-purchase and contractual  obligation  financing mechanisms
for State  facilities.  The Governor and the Legislative  leaders have indicated
that public  hearings  will be held on the  proposed  constitutional  amendment.
Before becoming effective,  the proposed constitutional  amendment must first be
passed again by the next  separately-elected  Legislature  and then  approved by
voters at a general election,  so that it could not become effective until after
the general election in November 1995.

THE CITY OF NEW YORK

     The fiscal  health of the State is closely  related to the fiscal health of
its  localities,  particularly  the City of New  York,  which has  required  and
continues to require significant financial assistance from the State. During the
1990 and 1991 fiscal  years,  the City  experienced  significant  shortfalls  in
almost all of its major tax sources and increases in social service  costs,  and
has been required to take actions to close  substantial  budget gaps in order to
maintain  balanced  budgets in accordance  with its financial  plan.  For fiscal
1993, the City achieved balanced operating results.

     In response to the City's financial crisis in 1975, the State took a number
of steps to assist  the City in  returning  to  fiscal  stability.  Among  these
actions, the State created the Municipal Assistance  Corporation for the City of
New York ("MAC") to provide  financing  assistance  to the City.  The State also
enacted the New York State Financial Emergency Act for the City of New York (the
"Financial  Emergency Act") which, among other things,  established the New York
State  Financial  Control  Board (the  "Control  Board")  to oversee  the City's
financial  affairs.  The State also  established  the Office of the State Deputy
Comptroller  for New York  ("OSDC")  in the Office of the State  Comptroller  to
assist the Control Board in exercising its powers and responsibilities.

     The City  operates  under a four  year  Financial  Plan  which is  prepared
annually and is  periodically  updated.  On June 30, 1986,  the Control  Board's
powers of approval over the City's Financial Plan were suspended pursuant to the
Financial  Emergency Act.  However,  the Control Board, MAC and OSDC continue to
exercise various monitoring functions relating to the City's financial position.
The City  submits its  financial  plans as well as the  periodic  updates to the
Control Board for its review.  In August 1993, the City submitted to the Control
Board its  1994-1997  Financial  Plan.  The  Financial  Plan projects a balanced
budget in fiscal 1994,  based on revenues of approximately  31.250 billion.  The
Financial Plan also predicts budget gaps of approximately $1.3 billion in fiscal
year 1995,  $1.8  billion in fiscal  year 1996 and $2.0  billion in fiscal  year
1997.

     Estimates  of the City's  revenues and  expenditures  are based on numerous
assumptions  and are subject to various  uncertainties.  If expected  federal or
State  aid  are not  forthcoming,  if  unforeseen  developments  in the  economy
significantly  reduce  revenues  derived from  economically  sensitive  taxes or
necessitate  increased  expenditures for public  assistance,  if the City should
negotiate wage increases for its employees greater than the amounts provided for
in the City's Financial Plan or if other  uncertainties  materialize that reduce
expected revenues or increase projected  expenditures,  then, to avoid operating
deficits,  the City may be required to implement  additional actions,  including
increases in taxes and  reductions in essential  City  services.  The City might
also seek additional assistance from the State.

AUTHORITIES

`New  York  State's   authorities  are  generally   responsible  for  financing,
constructing and operating  revenue-producing  public benefit facilities.  As of
September 30, 1992,  there were 18 Authorities that had outstanding debt of $100
million or more. The aggregate  outstanding debt,  including refunding bonds, of
these 18  Authorities  was $62.2  billion as of  September  30,  1992,  of which
approximately  $8.2 billion was moral  obligation debt and  approximately  $17.1
billion was financed under  lease-purchase or  contractual-obligation  financing
arrangements.  While Authorities are generally  supported by revenues generated,
financed or operated by projects of the Authorities,  in recent years, the State
has provided  financial  assistance  through  appropriations  to enable  certain
Authorities (in particular, the New York State Urban Development Corporation and
the New York State Housing Finance Agency) to meet their financial  obligations.
Further  assistance to these  Authorities is expected to be required to continue
in the future.

     The  Metropolitan   Transportation   Authority  (the  "MTA")  oversees  the
operation of New York City's bus and subway systems and,  through its affiliates
and  subsidiaries,  operates  certain  commuter  rail and bus  lines and a rapid
transit line.  Through an affiliate,  the MTA operates  certain  intrastate toll
bridges  and  tunnels.  The MTA has  depended  and will  continue to depend upon
Federal,  State, local government and agency support to operate the mass transit
portion of these operations because fare revenues are insufficient.  The MTA and
the commuter  railroads ended their 1991 fiscal year with their budgets balanced
on a cash basis. For 1993, a $69.8 million cash surplus has been projected.  The
1994 operating budget proposal projects a $66 million cash surplus.

     In 1981 the Legislature  authorized  procedures for the adoption,  approval
and amendment of a five year plan for a capital program  designed to upgrade the
performance of the MTA's transportation  systems and to supplement,  replace and
rehabilitate  facilities  and  equipment,  and also granted  certain  additional
bonding  authorization  for the capital  program.  The MTA has  submitted to the
State several 1992-96 Capital Program proposals which have been rejected.  A one
year  program of  approximately  $1.6  billion has been  deemed  approved in the
interim.

AGENCIES AND LOCALITIES

     Certain  localities  in  addition  to New York City  could  have  financial
problems leading to requests for additional State assistance  during the State's
1993-1994 fiscal year and thereafter.  The potential impact on the State of such
requests by localities is not included in the  projections of the State receipts
and disbursements in the State's 1993-1994 fiscal year.

     Fiscal difficulties experienced by the City of Yonkers ("Yonkers") resulted
in the  creation  of the  Financial  Control  Board of the City of Yonkers  (the
"Yonkers  Board")  by the  State in 1984.  The  Yonkers  Board is  charged  with
oversight of the fiscal affairs of Yonkers. Future actions taken by the Governor
or the State  Legislature  to assist Yonkers could result in allocation of State
resources in amounts that cannot yet be determined.

     Municipalities  and school districts have engaged in substantial short term
and long term  borrowing.  In 1991, the total  indebtedness of all localities in
the State was  approximately  $32.2 billion,  of which $16.8 billion was debt of
New York City (excluding $6.7 billion in Municipal Assistance Corporation debt);
a small portion of this indebtedness  represented borrowing to finance budgetary
deficits  and was issued  pursuant  to  enabling  State  legislation.  State law
requires  the  Comptroller  to review and make  recommendations  concerning  the
budgets of these local  government  units other than New York City authorized by
State law to finance  deficits during the period that such deficit  financing is
outstanding.   Fifteen  localities  had  outstanding  indebtedness  for  deficit
financing at the close of their fiscal years ending 1991.  In 1992, an unusually
large  number of local  government  units  requested  authorization  for deficit
financing.  According  to the  Comptroller,  ten local  governmental  units were
authorized to issue deficit financing in the aggregate amount of $131.1 million,
including  Nassau  County for $65 million in six-year  deficit bonds and Suffolk
County for $36 million in  six-year  deficit  bonds.  Certain  proposed  federal
expenditure reductions would reduce, or in some cases eliminate, federal funding
of some local  programs  and  accordingly  might  impose  substantial  increased
expenditure requirements on affected localities.  If the State, New York City or
any  of  the  Authorities   were  to  suffer  serious   financial   difficulties
jeopardizing  their  respective  access  to  the  public  credit  markets,   the
marketability of notes and bonds issued by localities  within the State could be
adversely  affected.  Localities also face  anticipated  and potential  problems
resulting from certain pending litigation,  judicial  decisions,  and long range
economic  trends.   The  longer  range  potential  problems  of  declining  city
population,  increasing  expenditures  and other economic trends could adversely
affect localities and require increasing State assistance in the future.

LITIGATION

     Certain  litigation  pending against the State or its officers or employees
could have a substantial  long term adverse effect on State finances.  Among the
more  significant  of these cases are those that  involve:  (1) the  validity of
agreements and treaties by which various Indian tribes  transferred title to the
state of certain  land in central and upstate New York;  (2) certain  aspects of
the State's  Medicaid rates and regulations;  (3) treatment  provided at several
state mental  health  facilities;  (4)  contamination  in the Love Canal area of
Niagara  Falls;  (5)  alleged  responsibility  of State  officials  to assist in
remedying  racial  segregation  in the City of Yonkers;  and (6)  challenges  to
certain public authority financial programs.

     Adverse  developments  in  those  proceedings  or  the  initiation  of  new
proceedings  could  affect  the  ability  of the State to  maintain  a  balanced
1993-1994 State  Financial  Plan. An adverse  decision in any of the above cited
proceedings  could exceed the amount of the Revised  1993-1994  State  Financial
Plan  reserve for the payment of  judgments  and,  therefore,  could  affect the
ability of the State to maintain a balanced 1993-1994 State Financial Plan.


                      KEYSTONE PENNSYLVANIA TAX FREE FUND

GENERAL

   
     The   Commonwealth  of   Pennsylvania,   the  fifth  most  populous  state,
historically  has been  identified  as a heavy  industry  state,  although  that
reputation  has  changed  with the  decline  of the  coal,  steel  and  railroad
industries and the resulting  diversification of the  Commonwealth's  industrial
composition.  The  major  new  sources  of  growth  are in the  service  sector,
including  trade,  medical  and  health  services,   educational  and  financial
institutions. Manufacturing has fallen behind in both the service sector and the
trade sector as a source of employment in Pennsylvania.  The Commonwealth is the
home  for  more  than  268,600  businesses  and the  headquarters  for 64  major
corporations.  Pennsylvania's  average  annual  unemployment  rate for the years
1988,  1989 and  1990  remained  slightly  below  the  nation's  annual  average
unemployment rate, and Pennsylvania's  average annual  unemployment rate for the
years 1991,  1992 and 1993 remained  slightly above the nation's  annual average
unemployment  rate. The unadjusted  unemployment  rate for both Pennsylvania and
the United States for April,  1995 was 5.8%.  The  population  of  Pennsylvania,
12,026  million  people in 1994  according  to the U.S.  Bureau  of the  Census,
represents  an increase  from the 1985  estimate of 11,772  million.  Per capita
income in Pennsylvania for 1993 of $20,352 was higher than the per capita income
of the United States of $20,817. The Commonwealth's General Fund, which receives
all tax receipts and most other  revenues and through  which debt service on all
general obligations of the Commonwealth are made, closed fiscal years ended June
30,  1991,  June 30,  1992 and June 30,  1993 with  fund  balances  of  negative
$980,936, positive $87,455 and positive $698,945, respectively.
    

DEBT

   
     The Commonwealth may incur debt to rehabilitate areas affected by disaster,
debt approved by the electorate, debt for certain capital projects (for projects
such as highways, public improvements, transportation assistance, flood control,
redevelopment  assistance,  site development and industrial development) and tax
anticipation  debt payable in the fiscal year of issuance.  The Commonwealth had
outstanding  general  obligation  debt of $5,075  million at June 30, 1994.  The
Commonwealth  is not  permitted to fund deficits  between  fiscal years with any
form of debt. All year-end deficit balances must be funded within the succeeding
fiscal year's budget. At November 29, 1994, all outstanding  general  obligation
bonds of the  Commonwealth  were rated AA- by Standard & Poor's  Corporation and
A-1 by  Moody's  Investors  Service,  Inc.  (see  Appendix  B).  There can be no
assurance  that these  ratings  will  remain in effect in the  future.  Over the
five-year  period ending June 30, 1999, the  Commonwealth  has projected that it
will issue notes and bonds totaling $2,293 million and retire bonded debt in the
principal amount of $2,448 million.

     Certain agencies created by the Commonwealth  have statutory  authorization
to incur debt for which Commonwealth  appropriations to pay debt service thereon
are not required. As of June 30, 1994, total combined debt outstanding for these
agencies was $5,995  million.  The debt of these agencies is supported by assets
of, or revenues  derived  from,  the  various  projects  financed  and is not an
obligation of the Commonwealth.  Some of these agencies, however, are indirectly
dependent on Commonwealth  appropriations.  The only  obligations of agencies in
the  Commonwealth  that bear a moral  obligation of the  Commonwealth  are those
issued by the  Pennsylvania  Housing  Finance Agency  ("PHFA"),  a state-created
agency which provides  housing for lower and moderate income  families,  and The
Hospitals  and  Higher  Education  Facilities  Authority  of  Philadelphia  (the
"Hospital Authority"),  an agency created by the City of Philadelphia to acquire
and  prepare  various  sites for use as  intermediate  care  facilities  for the
mentally retarded.
    

LOCAL GOVERNMENT DEBT

     Numerous local  government units in Pennsylvania  issue general  obligation
(i.e.,  backed by taxing  power) debt,  including  counties,  cities,  boroughs,
townships  and school  districts.  School  district  obligations  are  supported
indirectly by the Commonwealth. The issuance of non-electoral general obligation
debt is limited by  constitutional  and statutory  provisions.  Electoral  debt,
i.e., that approved by the voters, is unlimited.  In addition,  local government
units and municipal and other authorities may issue revenue obligations that are
supported by the revenues  generated from  particular  projects or  enterprises.
Examples include  municipal  authorities  (frequently  operating water and sewer
systems),   municipal  authorities  formed  to  issue  obligations   benefitting
hospitals and educational institutions,  and industrial development authorities,
whose obligations  benefit  industrial or commercial  occupants.  In some cases,
sewer or water revenue  obligations are guaranteed by taxing bodies and have the
credit characteristics of general obligations debt.

OTHER FACTORS

     The  performance  of  the  obligations  held  by  the  Fund  issued  by the
Commonwealth, its agencies,  subdivisions and instrumentalities are in part tied
to state-wide,  regional and local conditions within the Commonwealth and to the
creditworthiness of certain  non-Commonwealth  related obligors,  depending upon
the Pennsylvania  Fund's portfolio mix at any given time. Adverse changes to the
state-wide,  regional or local  economies or changes in government may adversely
affect   the   creditworthiness   of  the   Commonwealth,   its   agencies   and
municipalities,   and  certain   other   non-government   related   obligors  of
Pennsylvania tax-free obligations (e.g., a university, a hospital or a corporate
obligor).  The City of Philadelphia,  for example,  experienced severe financial
problems which  impaired its ability to borrow money and adversely  affected the
ratings of its obligations and their marketability. Conversely, some obligations
held by the Fund will be almost exclusively dependent on the creditworthiness of
one  underlying  obligor,  such as a project  occupant  or provider of credit or
liquidity support.


                          KEYSTONE TEXAS TAX FREE FUND

GENERAL

   
     The collapse of oil prices in the  mid-1980s  adversely  affected the Texas
economy due to the State's heavy  dependence on oil production.  The economy has
become more stable due to the  decreased  role of the oil and gas  industry  and
increased  diversification  into other  employment  sectors  such as the service
producing  sectors,  including  transportation  and public  utilities,  finance,
insurance, real estate, services, trade and government,  which are currently the
major sources of job growth in Texas.  Unlike the rest of the U.S., in Texas the
manufacturing  and  construction  industries  are growing  nearly as fast as the
service-producing  sector.  Construction  was the State's  fastest growing major
industry   through  1994.   Based  on  information  from  the  Texas  Employment
Commission,  non-farm  employment  in Texas has reached an all-time high of 7.82
million. Texas' jobless rate was 6.4% in 1994, compared to a national average of
6.1%.

     The  Comptroller of Public Accounts of the State of Texas predicts that the
overall Texas economy will out-pace national economic growth in the long term by
an annual average of more than one-half  percentage point. Of course,  there can
be no assurances  that this forecast will be realized.  Moreover,  even if it is
realized,  the State's economic  performance as a whole would not necessarily be
indicative  of the  financial  performance  of the  State or local  governments,
especially  in regions of the State which do not perform as well as the State as
a whole.

STATE GOVERNMENT REVENUES

     The state  government  ended  each of the past six  fiscal  years with cash
surpluses.  At the end of  fiscal  1994,  the State  had a $2,225  million  cash
balance in the general  revenue  fund,  as compared  with a $1,693  million cash
balance at the end of fiscal 1993.

     Historically,  the primary sources of the state government's  revenues have
been sales taxes,  mineral  severance taxes and federal  grants.  Federal grants
were the State's main revenue  source,  accounting  for 28.7% of state  revenues
during fiscal 1994,  while sales tax accounted for 26.7% of state revenue during
fiscal  1994.  The  remainder  of the State  government's  revenues  are derived
primarily from the motor fuels tax and other excise taxes, licenses, fees, fines
and  penalties,   and  interest  and  investment  income.   Much  of  the  State
government's  revenues  are special  revenues  which are  dedicated by the State
constitution or statute to specific  purposes which may be inconsistent with the
payment of debt service on State obligations.  In addition, the State government
manages two important trust funds--the  Permanent  University Fund and Permanent
School  Fund--endowed  with  proceeds  of the sale or lease of  dedicated  State
lands,  including mineral interests,  the income from which is  constitutionally
dedicated to the support of State  universities and public primary and secondary
schools, respectively.
    

     The State  constitution  prohibits  the State  government  from  levying ad
valorem taxes on property for general revenue purposes.  The State  constitution
also limits the rate of growth of appropriations from tax revenues not dedicated
by the constitution  during any biennium to the estimated rate of growth for the
State's economy.  The Legislature may avoid the constitutional  limitation if it
finds, by a majority vote of both houses,  that an emergency  exists.  The State
constitution authorizes the Legislature to provide by law for the implementation
of this restriction,  and the Legislature,  pursuant to such authorization,  has
defined  the  estimated  rate of  growth  in the  State's  economy  to mean  the
estimated increase in State personal income.

STATE GOVERNMENT DEBT

     With certain exceptions,  the Constitution generally prohibits the creation
of debt by or for the State. The limitations of the Constitution do not prohibit
the  issuance of revenue  bonds,  since the Texas  courts have held that certain
obligations which are not payable from tax sources do not create a "debt" within
the meaning of the  Constitution.  The State and  various  state  agencies  have
issued revenue bonds payable from the revenues  produced by various  facilities.
Furthermore,  obligations  which are payable from funds expected to be available
during the current budget period do not constitute  "debt" within the meaning of
the Constitution.  Short term obligations,  such as tax and revenue anticipation
notes which the  Treasurer  is  authorized  to issue  solely to  coordinate  the
State's  cash flow  within a fiscal  year,  and which must mature and be paid in
full during the  biennium in which they were  issued,  are not deemed to be debt
within  the  meaning  of the  constitutional  prohibition.  In  addition,  State
agencies may issue  revenue  bonds payable from payments to be made by the State
government for a lease or purchase of financed  facilities,  subject to biennial
appropriations.  These bonds are  considered  "moral  obligations"  of the State
government,  since failure to appropriate  funds could injure the State's credit
in the marketplace, although the State government is not legally obligated to do
so.

   
     At times, the voters of Texas, by constitutional amendment, have authorized
the issuance of debt by the State,  including general obligation bonds backed by
the full  faith and  credit of the  State.  In some  cases the  authorized  debt
requires the approval of the Legislature, but in other cases, the constitutional
amendments permit the debt to be issued without specific  legislative action. Of
the general  obligation  bonds authorized by the State's voters through November
30, 1994, $4.5 billion then remained outstanding and an additional $3.86 billion
were yet to be  issued.  These  bonds  include  bonds  that may be issued by the
Veterans'  Land Board for  veterans  to  purchase  land and  housing,  the Water
Development Board for conservation and development of water resources, the Parks
and Wildlife  Department for  acquisition  and  development of state parks,  the
Texas  Higher  Education  Coordinating  Board  to  finance  student  loans,  the
Department of Agriculture for the purchase of farm and ranch real estate,and the
Texas Public Finance Authority to finance,  repair and construct facilities such
as  corrections  and mental health  institutions.  In addition,  the voters have
authorized  the  respective  Boards of Regents of the University of Texas System
and the Texas A&M University  System to issue bonds payable from income from the
Permanent  University  Fund  up to 30%  of  the  book  value  of  the  Permanent
University  Fund,  exclusive of real estate at the time of issuance.  The voters
have also authorized the appropriation of the first $100 million coming into the
State Treasury, and not otherwise appropriated by the Constitution,  to pay debt
service on bonds issued by other state colleges and universities in the State.
    

LOCAL GOVERNMENT REVENUES

     Various  state laws place limits upon the amounts of tax that can be levied
upon the property subject to ad valorem taxes within various taxing units,  such
as cities, counties and districts which have ad valorem taxing powers (including
without limitation, school and hospital districts). Because ad valorem taxes are
computed upon the appraised  property  valuations  and property  appraisals  are
required to be conducted only every three years,  it may be several years before
any  decline  in  property   values  will  be  reflected  in  decreases  in  tax
collections.  Conversely,  there  may be a  similar  lag  time  before a rise in
property values results in increased ad valorem tax collections.

FUNDING OF PUBLIC EDUCATION

   
     On May 31, 1993,  the Texas  governor  signed a  comprehensive  legislative
revision to the school  finance  provisions  of the Texas  Education  Code.  The
legislative revision resulted from a series of court decisions commonly referred
to as Edgewood v. Kirby, in which Texas courts declared the Texas school finance
system  unconstitutional  under Texas law.  Generally,  the courts  declared the
school finance system unconstitutional because there must be a "direct and close
correlation  between a  district's  tax  effort  and the  educational  resources
available to it," and because districts must have "substantially equal access to
similar revenues per pupil at similar levels of tax effort."

     The Texas  school  finance  system is funded  from a  combination  of local
school  district ad valorem  taxes,  State funds from the Permanent  School Fund
endowment and certain designated tax revenues,  and state  appropriation.  "Tier
one" funding  guarantees a school  district a basic  allotment per pupil;  "tier
two"  funding  guarantees  a school  district a certain  amount of  "enrichment"
revenue  per  student to the extent the local  school  district  sets a tax rate
above $0.86 per $100 assessed valuation.

     As under prior law, the legislative  revision  retains a two tier system of
finance.  Under the  legislative  revision,  if a  district's  adjusted  taxable
property wealth per student exceeds $280,000,  the district must exercise one of
five operations to reduce its wealth per student to that level:  consolidate the
district  with a  property-poor  district  for  all  purposes;  consolidate  the
district  with a  property-poor  district  solely for  purposes  of levying  and
distributing  either  maintenance,  taxes or both  maintenance  and debt service
taxes;  detach  property  from the district for  annexation  by a  property-poor
district;  purchase an attendance credit by paying tax revenues to the State for
redistribution to property-poor  districts; or contract to educate students in a
property-poor district at the wealthy district's expense. If a district fails to
exercise a permitted option,  the Commissioner of Education must detach mineral,
utility,  industrial,  or  commercial  property  from the district and annex the
property to a property-poor district or, if necessary,  consolidate the district
with a property-poor district.

     On January 30, 1995,  the Texas  Supreme  Court ruled that the  legislative
revision is constitutional in all respects. It suggested,  however, that further
changes may be needed in the near future to provide  equal access to funding for
capital projects as well as for operations.  The Texas  Legislature is currently
considering  legislation  which  attempts  to  provide  such  equalization.  The
legislative  revision and future  efforts to equalize  school funding may affect
the financial  condition of the Texas State  Government and certain Texas school
districts.
    

     Public higher  education in the State is funded  through a  combination  of
tuition,  student fees and other local funds (including gifts from benefactors),
income  from  the  Permanent  University  Fund  and  appropriations  made by the
Legislature.  Tuition rates are set by the Legislature, except that institutions
may double the tuition rate for graduate students.  Many student fees are set by
the boards of regents of the various colleges and universities.

OTHER FACTORS

   
     The Texas Fund  expects to invest its assets in general  obligation  bonds,
moral  obligation  bonds,  and  revenue  bonds  issued  by the  State  and local
governments  to  finance  their own  works or to  finance  private  enterprises.
Payment of the revenue  bonds will depend on the  financial  performance  of the
enterprises  financed,  which may include  public  water,  sewer,  and  electric
utility  systems,   municipal  airports,   nonprofit   hospitals,   multi-family
residential  housing  developments,  portfolios  of  single-family  mortgages or
student loans, and other  enterprises.  The performance of these enterprises may
be  affected  by  industry  trends,  competition,  labor  relations,  prevailing
interest  rates,  and similar  factors which cannot be predicted with certainty.
Payment of  general  and moral  obligation  bonds  will  depend  upon the future
financial  condition  of the issuing  governments  and their other  obligations,
including   obligations   concerning   public  education,   criminal   detention
facilities, and other matters which have been or hereafter may be imposed by the
courts. The financial  performance of financed enterprises and local governments
could be adversely affected not only by any downturn in the State's economy as a
whole, but also by regional or local factors such as closings of military bases,
any layoffs by large employers.

                                   APPENDIX B


                      CORPORATE AND MUNICIPAL BOND RATINGS

S&P CORPORATE AND MUNICIPAL BOND RATINGS

A.       MUNICIPAL NOTES

         An S&P note rating  reflects the  liquidity  concerns and market access
risks  unique to notes.  Notes due in three years or less will likely  receive a
note  rating.  Notes  maturing  beyond  three years will most  likely  receive a
long-term  debt  rating.   The  following  criteria  are  used  in  making  that
assessment:

         a.  Amortization  schedule (the larger the final  maturity  relative to
other maturities the more likely it will be treated as a note), and

         b. Source of payment (the more dependent the issue is on the market for
its refinancing, the more likely it will be treated as a note).

         Note ratings are as follows:

         1. 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.

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

         3. SP-3 - Speculative capacity to pay principal and interest.

B.       TAX EXEMPT DEMAND BONDS

         S&P assigns  "dual"  ratings to all long-term  debt issues that have as
part of their provisions a demand or double feature.

         The first rating addresses the likelihood of repayment of principal and
interest as due, and the second rating  addresses only the demand  feature.  The
long-term  debt  rating  symbols  are used for  bonds to  denote  the  long-term
maturity  and the  commercial  paper  rating  symbols are used to denote the put
option (for example,  "AAA/A-1+"). For the newer "demand notes," S&P note rating
symbols,  combined with the  commercial  paper  symbols,  are used (for example,
"SP-1+/A-1+" ).

C.       CORPORATE AND MUNICIPAL BOND RATINGS

         An S&P  corporate or municipal  bond rating is a current  assessment of
the  creditworthiness  of an obligor,  including obligors outside the U.S., with
respect to a specific  obligation.  This assessment may take into  consideration
obligors such as guarantors, insurers or lessees. Ratings of foreign obligors do
not take into account currency exchange and related  uncertainties.  The ratings
are based on current information furnished by the issuer or obtained by S&P from
other sources it considers reliable.

         The  ratings  are  based,   in  varying   degrees,   on  the  following
considerations:

         a. Likelihood of default and capacity and willingness of the obligor as
to the timely payment of interest and repayment of principal in accordance  with
the terms of the obligation;

         b. Nature of and provisions of the obligation; and

         c.  Protection  afforded by and relative  position of the obligation in
the event of bankruptcy  reorganization  or other  arrangement under the laws of
bankruptcy and other laws affecting creditors' rights.

         PLUS (+) OR MINUS (-): To provide more detailed  indications  of credit
quality, ratings from "AA" to "BBB" may be modified by the addition of a plus or
minus sign to show relative standing within the major rating categories.

         A  provisional  rating  is  sometimes  used  by  S&P.  It  assumes  the
successful  completion of the project being financed by the debt being rated and
indicates  that  payment of debt  service  requirements  is largely or  entirely
dependent upon the successful and timely completion of the project. This rating,
however,  while  addressing  credit  quality  subsequent  to  completion  of the
project,  makes no comment  on the  likelihood  of, or the risk of default  upon
failure of, such completion.

C.       BOND RATINGS ARE AS FOLLOWS:

         a.  AAA - Debt  rated  AAA  has the  highest  rating  assigned  by S&P.
Capacity to pay interest and repay principal is extremely strong.

         b. AA - Debt rated AA has a very strong  capacity to pay  interest  and
repay principal and differs from the higher rated issues only in small degree.

         3. A - Debt rated A has a strong  capacity  to pay  interest  and repay
principal  although it is somewhat more  susceptible  to the adverse  effects of
changes in  circumstances  and  economic  conditions  than debt in higher  rated
categories.

         4. BBB - Debt rated BBB is regarded  as having an adequate  capacity to
pay  interest  and  repay  principal.  Whereas  it  normally  exhibits  adequate
protection parameters, adverse economic conditions or changing circumstances are
more likely to lead to a weakened  capacity to pay interest and repay  principal
for debt in this category than in higher rated categories.

         5. BB, B, CCC, CC and C - Debt rated BB, B, CCC, CC and C is  regarded,
on  balance,  as  predominantly  speculative  with  respect to  capacity  to pay
interest and repay prncipal in accordance with the terms of teh  obligation.  BB
indicates  the  lowest  degree  of  speculation  and C  the  highest  degree  of
speculation.  While  such debt will  likely  have some  quality  and  protective
characteristics,  these are  outweighed  by large  uncertainties  or major  risk
exposures to adverse conditions.

D.       MOODY'S CORPORATE AND MUNICIPAL BOND RATINGS

         Moody's ratings are as follows:

         1.  Aaa - Bonds  which  are  rated  Aaa are  judged  to be of the  best
quality.  They carry the smallest  degree of  investment  risk and are generally
referred to as "gilt-edge."  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.

         2. Aa - Bonds  which are rated Aa are  judged to be of high  quality by
all  standards.  Together  with the Aaa group they  comprise  what are generally
known as high grade  bonds.  They are rated  lower  than the best bonds  because
margins of protection may not be as large as in Aaa securities 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.

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

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

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

         6. B - Bonds which are rated B generally  lack  characteristics  of the
desirable  investment.  Assurance  of  interst  and  principal  payments  or  of
maintenance  of other terms of the contract  over any long period of time may be
small.

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

         Con.  (---) - Municipal  bonds for which the security  depends upon the
completion  of  some  act  or  the  fulfillment  of  some  condition  are  rated
conditionally.  These  are bonds  secured  by (a)  earnings  of  projects  under
construction,  (b) earnings of projects unseasoned in operation experience,  (c)
rentals which begin when facilities are completed, or (d) payments to which some
other limiting condition attaches.  Parenthetical rating denotes probable credit
stature upon completion of construction or elimination of basis of condition.

         Those  municipal  bonds in the Aa,  A,  and Baa  groups  which  Moody's
believes  possess the  strongest  investment  attributes  are  designated by the
symbols Aa 1, A 1, and Baa 1.


                            MONEY MARKET INSTRUMENTS

         Money market  securities are instruments  with remaining  maturities of
one year or less such as bank  certificates  of deposit,  bankers'  acceptances,
commercial paper (including  variable rate master demand notes), and obligations
issued or guaranteed by the U.S. government,  its agencies or instrumentalities,
some of which may be subject to repurchase agreements.

COMMERCIAL PAPER

         Commercial  paper will  consist of issues rated at the time of purchase
A-1, by Standard & Poor's  Corporation  (S&P),  or Prime-1 by Moody's  Investors
Service, Inc., (Moody's) or F-1 by Fitch Investors Services, Inc. (Fitch's); or,
if not rated,  will be issued by companies which have an outstanding  debt issue
rated at the time of purchase  Aaa, Aa or A by Moody's,  or AAA, AA or A by S&P,
or will be determined by Keystone to be of comparable quality.

A.       S&P RATINGS

         An  S&P  commercial  paper  rating  is  a  current  assessment  of  the
likelihood of timely payment of debt having an original maturity of no more than
365 days.  Ratings are graded  into four  categories,  ranging  from "A" for the
highest  quality  obligations  to "D" for the  lowest.  The top  category  is as
follows:

         1. A: Issues  assigned  this highest  rating are regarded as having the
greatest  capacity for timely  payment.  Issues in this category are  delineated
with the numbers 1, 2 and 3 to indicate the relative degree of safety.

         2. A-1: This designation  indicates that the degree of safety regarding
timely payment is either overwhelming or very strong. Those issues determined to
possess  overwhelming  safety  characteristics  are denoted with a plus (+) sign
designation.

B.       MOODY'S RATINGS

         The  term  "commercial  paper"  as used  by  Moody's  means  promissory
obligations  not having an original  maturity in excess of nine months.  Moody's
commercial  paper  ratings  are  opinions  of the  ability  of  issuers to repay
punctually  promissory  obligations not having an original maturity in excess of
nine months. Moody's employs the following designation,  judged to be investment
grade, to indicate the relative repayment capacity of rated issuers.

         1. The rating PRIME-1 is the highest  commercial  paper rating assigned
by Moody's.  Issuers  rated  PRIME-1 (or related  supporting  institutions)  are
deemed to have a  superior  capacity  for  repayment  of short  term  promissory
obligations.  Repayment capacity of Prime-1 issuers is normally evidenced by the
following characteristics:

         1)       leading market positions in well-established industries;
         2)       high rates of return on funds employed;

         3)       conservative  capitalization structures with moderate reliance
                  on debt and ample asset protection;

         4)       broad margins in earnings  coverage of fixed financial charges
                  and high internal cash generation; and

         5)       well  established  access to a range of financial  markets and
                  assured sources of alternate liquidity.

         In assigning  ratings to issuers whose commercial paper obligations are
supported by the credit of another  entity or entities,  Moody's  evaluates  the
financial strength of the affiliated  corporations,  commercial banks, insurance
companies,  foreign governments or other entities, but only as one factor in the
total rating assessment.

CERTIFICATES OF DEPOSIT

         Certificates  of deposit are receipts  issued by a bank in exchange for
the  deposit  of funds.  The  issuer  agrees to pay the  amount  deposited  plus
interest to the bearer of the receipt on the date specified on the  certificate.
The certificate usually can be traded in the secondary market prior to maturity.

         Certificates  of deposit  will be  limited  to U.S.  dollar-denominated
certificates of U.S. banks or of savings and loan associations,  including their
branches abroad, and of U.S. branches of foreign banks, which are members of the
Federal Reserve System or the Federal Deposit Insurance Corporation, and have at
least $1 billion in  deposits  as of the date of their most  recently  published
financial statements.

         The Funds will not acquire time deposits or  obligations  issued by the
International  Bank for  Reconstruction  and Development,  the Asian Development
Bank or the  Inter-American  Development  Bank.  Additionally,  the Funds do not
currently  intend to  purchase  foreign  securities  (except to the extent  that
certificates of deposit of foreign  branches of U.S. banks may be deemed foreign
securities) or purchase  certificates of deposit,  bankers' acceptances or other
similar obligations issued by foreign banks.

BANKERS' ACCEPTANCES

         Bankers'   acceptances   typically   arise   from   short-term   credit
arrangements designed to enable businesses to obtain funds to finance commercial
transactions.  Generally,  an  acceptance  is a time draft drawn on a bank by an
exporter or an importer to obtain a stated  amount of funds to pay for  specific
merchandise.  The  draft  is  then  "accepted"  by the  bank  that,  in  effect,
unconditionally  guarantees  to pay the  face  value  of the  instrument  on its
maturity  date.  The  acceptance  may then be held by the  accepting  bank as an
earning  asset or it may be sold in the  secondary  market at the going  rate of
discount for a specific maturity.  Although maturities for acceptances can be as
long as 270  days,  most  acceptances  have  maturities  of six  months or less.
Bankers'  acceptances  acquired  by a Fund  must  have  been  accepted  by  U.S.
commercial banks,  including foreign branches of U.S.  commercial banks,  having
total  deposits  at the time of  purchase  in excess of $1  billion  and must be
payable in U.S. dollars.

U.S. GOVERNMENT SECURITIES

         Securities  issued  or  guaranteed  by the U.S.  government  include  a
variety  of  Treasury  securities  that  differ  only in their  interest  rates,
maturities  and  dates of  issuance  and  securities  issued  by the  Government
National Mortgage Association (GNMA). Treasury bills have maturities of one year
or less.  Treasury notes have  maturities of one to ten years and Treasury bonds
generally  have  maturities  of greater  than ten years at the date of issuance.
GNMA securities include GNMA mortgage pass-through certificates. Such securities
are supported by the full faith and credit of the U.S.

         Securities  issued  or  guaranteed  by  U.S.   government  agencies  or
instrumentalities include securities issued or guaranteed by the Federal Housing
Administration,  Farmers Home  Administration,  Export-Import  Bank of the U.S.,
Small Business Administration, General Services Administration, Central Bank for
Cooperatives,  Federal  Home Loan  Banks,  Federal  Loan  Mortgage  Corporation,
Federal Intermediate Credit Banks, Federal Land Banks, Maritime  Administration,
The Tennessee  Valley  Authority,  District of Columbia Armory Board and Federal
National Mortgage Association.

         Some  obligations of U.S.  government  agencies and  instrumentalities,
such as securities of Federal Home Loan Banks, are supported by the right of the
issuer to borrow from the Treasury.  Others, such as bonds issued by the Federal
National Mortgage Association, a private corporation,  are supported only by the
credit of the  instrumentality.  Because the U.S. government is not obligated by
law to provide support to an instrumentality it sponsors,  a Fund will invest in
the securities issued by such an instrumentality  only when Keystone  determines
under  standards  established by the Board of Trustees that the credit risk with
respect  to  the  instrumentality  does  not  make  its  securities   unsuitable
investments. U.S. government securities do not include international agencies or
instrumentalities   in   which   the   U.S.   government,    its   agencies   or
instrumentalities participate, such as the World Bank, Asian Development Bank or
the  Inter-American  Development  Bank, or issues insured by the Federal Deposit
Insurance Corporation.

MUNICIPAL LEASE OBLIGATIONS

         Municipal lease obligations purchased primarily through Certificates of
Participation  ("CPO's") are used by state and local  governments to finance the
purchase of property,  and function much like installment purchase  obligations.
The payments made by the municipality under the lease are used to repay interest
and  principal on the bonds issued to purchase  the  property.  Once these lease
payments are completed,  the municipality  gains ownership of the property for a
nominal sum. The lessor is, in effect,  a lender  secured by the property  being
leased. A feature which distinguishes CPOs from municipal debt is that the lease
which is the subject of the  transaction  must contain a  "nonappropriation"  or
"abatement" clause. A nonappropriation clause provides that provides that, while
the  municipality  will  use its  best  efforts  to  make  lease  payments,  the
municipality  may  terminate  the lease  without  penalty if the  municipality's
appropriating body does not allocate the necessary funds. Local administrations,
being faced with increasingly  tight budgets,  therefore have more discretion to
curtail  payments under COPs than they do to curtail  payments on  traditionally
funded  debt  obligations.   If  the  government  lessee  does  not  appropriate
sufficient  monies to make lease payments,  the lessor or its agent is typically
entitled to repossess the property.  In most cases,  however, the private sector
value of the  property  will be less than the amount the  government  lessee was
paying.

         Criteria  considered  by the rating  agencies and Keystone in assessing
the risk of  appropriation  include the issuing  municipality's  credit  rating,
evaluation of how essential the leased property is to the  municipality and term
of the lease  compared to the useful life of the leased  property.  The Board of
Trustees  reviews  the COPs held in each  Fund's  portfolio  to assure that they
constitute liquid  investments based on various factors reviewed by Keystone and
monitored  by the Board.  Such  factors  include (a) the credit  quality of such
securities  and the extent to which they are rated or, if  unrated,  comply with
existing  criteria  and  procedures  followed to ensure that they are of quality
comparable  to the ratings  required  for each Fund's  investment,  including an
assessment of the likelihood that the leases will not be cancelled; (b) the size
of the municipal  securities  market,  both in general and with respect to COPs;
and (c) the extent to which the type of COPs held by each Fund trade on the same
basis and with the same degree of dealer  participation as other municipal bonds
of comparable credit rating or quality.


               FUTURES CONTRACTS AND RELATED OPTIONS TRANSACTIONS

         The Funds intend to enter into financial  futures  contracts as a hedge
against  changes  in  prevailing  levels  of  interest  rates  to seek  relative
stability of principal and to establish more definitely the effective  return on
securities  held or  intended  to be  acquired  by a Fund or as a hedge  against
changes in the prices of securities  held by a Fund or to be acquired by a Fund.
A Fund's hedging may include sales of futures as an offset against the effect of
expected  increases  in interest  rates or  securities  prices and  purchases of
futures as an offset against the effect of expected declines in interest rates.

         For example,  when a Fund  anticipates a  significant  market or market
sector  advance,  it will  purchase a stock  index  futures  contract as a hedge
against  not  participating  in such  advance at a time when a Fund is not fully
invested.  The purchase of a futures  contract serves as a temporary  substitute
for the  purchase of  individual  securities  which may then be  purchased in an
orderly fashion. As such purchases are made, an equivalent amount of index based
futures contracts would be terminated by offsetting  sales. In contrast,  a Fund
would sell stock index  futures  contracts  in  anticipation  of or in a general
market or market sector  decline that may  adversely  affect the market value of
the Fund's  portfolio.  To the extent that the Fund's portfolio changes in value
in correlation with a given index,  the sale of futures  contracts on that index
would  substantially  reduce the risk to the  portfolio  of a market  decline or
change in  interest  rates,  and,  by doing so,  provide an  alternative  to the
liquidation  of the Fund's  securities  positions and the resulting  transaction
costs.

         The Funds intend to engage in options transactions which are related to
financial  futures  contracts for hedging  purposes and in  connection  with the
hedging strategies described above.

         Although techniques other than sales and purchases of futures contracts
and related options  transactions could be used to reduce the Funds' exposure to
interest rate and/or market  fluctuations,  the Funds may be able to hedge their
exposure  more  effectively  and perhaps at a lower cost through  using  futures
contracts  and related  options  transactions.  While the Funds do not intend to
take delivery of the  instruments  underlying  futures  contracts they hold, the
Funds do not intend to engage in such futures contracts for speculation.

FUTURES CONTRACTS

         Futures  contracts are  transactions in the commodities  markets rather
than in the securities  markets. A futures contract creates an obligation by the
seller to deliver to the buyer the  commodity  specified  in the  contract  at a
specified  future time for a specified  price.  The futures  contract creates an
obligation  by the buyer to accept  delivery  from the  seller of the  commodity
specified at the specified future time for the specified  price. In contrast,  a
spot transaction  creates an immediate  obligation for the seller to deliver and
the buyer to accept delivery of and pay for an identified commodity. In general,
futures contracts involve  transactions in fungible goods such as wheat,  coffee
and  soybeans.  However,  in the last  decade an  increasing  number of  futures
contracts have been developed which specify financial instruments or financially
based indexes as the underlying commodity.

         U.S. futures  contracts are traded only on national  futures  exchanges
and are  standardized as to maturity date and underlying  financial  instrument.
The principal  financial futures exchanges in the United States are The Board of
Trade of the City of Chicago, the Chicago Mercantile Exchange, the International
Monetary Market (a division of the Chicago  Mercantile  Exchange),  the New York
Futures  Exchange and the Kansas City Board of Trade.  Each exchange  guarantees
performance  under  contract  provisions  through  a  clearing  corporation,   a
nonprofit  organization  managed  by the  exchange  membership,  which  is  also
responsible for handling daily  accounting of deposits or withdrawals of margin.
A futures commission  merchant ("Broker") effects each transaction in connection
with futures  contracts  for a  commission.  Futures  exchanges  and trading are
regulated  under the  Commodity  Exchange Act by the Commodity  Futures  Trading
Commission ("CFTC") and National Futures Association ("NFA").


INTEREST RATE FUTURES CONTRACTS

         The sale of an interest rate futures  contract creates an obligation by
a Fund, as seller, to deliver the type of financial  instrument specified in the
contract at a specified  future time for a specified  price.  The purchase of an
interest rate futures contract creates an obligation by a Fund, as purchaser, to
accept  delivery of the type of  financial  instrument  specified at a specified
future  time  for a  specified  price.  The  specific  securities  delivered  or
accepted,  respectively, at settlement date, are not determined until at or near
that date. The  determination is in accordance with the rules of the exchange on
which the futures contract sale or purchase was made.

         Currently,  interest rate futures contracts can be purchased or sold on
90-day U.S.  Treasury  bills,  U.S.  Treasury  bonds,  U.S.  Treasury notes with
maturities between 6 1/2 and 10 years,  Government National Mortgage Association
(GNMA)  certificates,  90-day  domestic  bank  certificates  of deposit,  90-day
commercial paper, and 90-day Eurodollar  certificates of deposit. It is expected
that futures  contracts  trading in  additional  financial  instruments  will be
authorized. The standard contract size is $100,000 for futures contracts in U.S.
Treasury bonds,  U.S. Treasury notes and GNMA  certificates,  and $1,000,000 for
the other designated  contracts.  While U.S. Treasury bonds, U.S. Treasury bills
and U.S.  Treasury  notes are  backed by the full  faith and  credit of the U.S.
government and GNMA certificates are guaranteed by a U.S. government agency, the
futures contracts in U.S.
government securities are not obligations of the U.S. Treasury.

INDEX BASED FUTURES CONTRACTS, OTHER THAN STOCK INDEX BASED

         It is  expected  that  bond  index and other  financially  based  index
futures  contracts will be developed in the future.  It is anticipated that such
index based futures  contracts will be structured in the same way as stock index
futures  contracts  but will be measured by changes in interest  rates,  related
indexes or other  measures,  such as the consumer price index. In the event that
such futures  contracts are  developed,  the Funds will sell interest rate index
and other index based  futures  contracts  to hedge  against  changes  which are
expected to affect the Funds' portfolios.

         The purchase or sale of a futures contract differs from the purchase or
sale of a security, in that no price or premium is paid or received. Instead, to
initiate trading an amount of cash, cash equivalents,  money market instruments,
or U.S.  Treasury bills equal to approximately 1 1/2% (up to 5%) of the contract
amount  must be  deposited  by a Fund with the  Broker.  This amount is known as
initial  margin.  The  nature of  initial  margin  in  futures  transactions  is
different from that of margin in security transactions.  Futures contract margin
does not  involve  the  borrowing  of  funds  by the  customer  to  finance  the
transactions.  Rather, the initial margin is in the nature of a performance bond
or  good  faith  deposit  on the  contract  which  is  returned  to a Fund  upon
termination of the futures  contract  assuming all contractual  obligations have
been satisfied.  The margin required for a particular futures contract is set by
the exchange on which the contract is traded and may be  significantly  modified
from time to time by the exchange during the term of the contract.

         Subsequent  payments,  called variation  margin, to the Broker and from
the Broker, are made on a daily basis as the value of the underlying  instrument
or index fluctuates  making the long and short positions in the futures contract
more or less valuable,  a process known as mark-to-market.  For example,  when a
Fund has purchased a futures contract and the price of the underlying  financial
instrument or index has risen,  that position will have increased in value,  and
the Fund will receive from the Broker a variation  margin  payment equal to that
increase in value. Conversely, where a Fund has purchased a futures contract and
the price of the  underlying  financial  instrument or index has  declined,  the
position  would be less  valuable  and the  Fund  would  be  required  to make a
variation  margin payment to the Broker.  At any time prior to expiration of the
futures contract,  a Fund may elect to close the position. A final determination
of variation  margin is then made,  additional cash is required to be paid to or
released by the Broker, and the Fund realizes a loss or gain.

         The FUND intends to enter into arrangements with its custodian and with
Brokers to enable the initial  margin of a Fund and any  variation  margin to be
held in a segregated account by its custodian on behalf of the Broker.

         Although interest rate futures contracts by their terms call for actual
delivery  or  acceptance  of  financial  instruments,  and index  based  futures
contracts  call for the  delivery  of cash equal to the  difference  between the
closing value of the index on the expiration  date of the contract and the price
at which the futures  contract is  originally  made,  in most cases such futures
contracts are closed out before the settlement date without the making or taking
of delivery.  Closing out a futures  contract  sale is effected by an offsetting
transaction in which a Fund enters into a futures contract purchase for the same
aggregate amount of the specific type of financial  instrument or index and same
delivery  date.  If the price in the sale  exceeds  the price in the  offsetting
purchase,  the Fund is paid the  difference  and thus  realizes  a gain.  If the
offsetting  purchase price exceeds the sale price,  the Fund pays the difference
and realizes a loss.  Similarly,  the closing out of a futures contract purchase
is effected by an offsetting  transaction  in which a Fund enters into a futures
contract sale. If the offsetting sale price exceeds the purchase price, the Fund
realizes a gain.  If the purchase  price exceeds the  offsetting  sale price the
Fund realizes a loss.  The amount of the Fund's gain or loss on any  transaction
is reduced or increased,  respectively,  by the amount of any transaction  costs
incurred by the Fund.

         As an example of an offsetting transaction, the contractual obligations
arising  from the sale of one contract of September  U.S.  Treasury  bills on an
exchange  may be  fulfilled  at any time  before  delivery  of the  contract  is
required  (i.e. on a specified date in September,  the "delivery  month") by the
purchase of one contract of September U.S.  Treasury bills on the same exchange.
In such instance the difference  between the price at which the futures contract
was sold and the price paid for the  offsetting  purchase,  after  allowance for
transaction costs, represents the profit or loss to a Fund.

         There can be no assurance,  however,  that a Fund will be able to enter
into an  offsetting  transaction  with  respect to a  particular  contract  at a
particular time. If a Fund is not able to enter into an offsetting  transaction,
the Fund will  continue to be required  to maintain  the margin  deposits on the
contract and to complete the contract according to its terms.

OPTIONS ON FINANCIAL FUTURES

         The Funds intend to purchase call and put options on financial  futures
contracts  and sell such options to terminate an existing  position.  Options on
futures  are  similar to options  on stocks  except  that an option on a futures
contract  gives the  purchaser  the right,  in return for the premium  paid,  to
assume a position in a futures contract (a long position if the option is a call
and a short  position  if the option is a put)  rather  than to purchase or sell
stock at a specified exercise price at any time during the period of the option.
Upon exercise of the option,  the delivery of the futures position by the writer
of the option to the holder of the option will be accompanied by delivery of the
accumulated  balance  in  the  writer's  futures  margin  account.  This  amount
represents  the  amount by which the market  price of the  futures  contract  at
exercise exceeds,  in the case of a call, or is less than, in the case of a put,
the  exercise  price of the  option  on the  futures  contract.  If an option is
exercised the last trading day prior to the expiration  date of the option,  the
settlement  will be made  entirely in cash equal to the  difference  between the
exercise price of the option and value of the futures contract.

         The Funds  intend to use  options on  financial  futures  contracts  in
connection with hedging strategies. In the future the Funds may use such options
for other purposes.

PURCHASE OF PUT OPTIONS ON FUTURES CONTRACTS

         The purchase of protective put options on financial  futures  contracts
is analogous to the purchase of protective puts on individual  stocks,  where an
absolute  level of protection is sought below which no additional  economic loss
would be incurred by a Fund.  Put options may be  purchased to hedge a portfolio
of stocks or debt  instruments or a position in the futures  contract upon which
the put option is based.

PURCHASE OF CALL OPTIONS ON FUTURES CONTRACTS

         The purchase of call options on financial futures contracts  represents
a means of obtaining  temporary exposure to market appreciation at limited risk.
It is analogous to the purchase of a call option on an individual  stock,  which
can be used as a substitute for a position in the stock itself. Depending on the
pricing of the option  compared to either the futures  contract upon which it is
based, or upon the price of the underlying financial instrument or index itself,
purchase of a call option may be less risky than the  ownership  of the interest
rate or index based futures contract or the underlying securities.  Call options
on commodity  futures  contracts  may be purchased to hedge  against an interest
rate increase or a market advance when a Fund is not fully invested.

USE OF  NEW  INVESTMENT  TECHNIQUES  INVOLVING  FINANCIAL  FUTURES  CONTRACTS OR
RELATED OPTIONS

         The Funds may  employ new  investment  techniques  involving  financial
futures contracts and related options. The Funds intend to take advantage of new
techniques in these areas which may be developed from time to time and which are
consistent  with the Fund's  investment  objective.  The FUND  believes  that no
additional  techniques  have been  identified for employment by the Funds in the
foreseeable future other than those described above.

LIMITATIONS  ON  PURCHASE  AND  SALE OF FUTURES CONTRACTS AND RELATED OPTIONS ON
SUCH FUTURES CONTRACTS

         A Fund will not enter into a futures  contract if, as a result thereof,
more than 5% of the Fund's  total  assets  (taken at market value at the time of
entering  into the  contract)  would be  committed  to margin  deposits  on such
futures contracts.

         The  Funds  intend  that its  futures  contracts  and  related  options
transactions  will be entered into for traditional  hedging  purposes.  That is,
futures  contracts  will be sold to  protect  against a decline  in the price of
securities that a Fund owns, or futures contracts will be purchased to protect a
Fund against an increase in the price of securities it intends to purchase.  The
Funds do not intend to enter into futures contracts for speculation.

         In instances  involving the purchase of futures contracts by a Fund, an
amount of cash and cash  equivalents,  equal to the market  value of the futures
contracts  will be deposited in a segregated  account with the FUND's  custodian
and/or in a margin  account  with a Broker to  collateralize  the  position  and
thereby insure that the use of such futures is unleveraged.

FEDERAL INCOME TAX TREATMENT

         For federal  income tax  purposes,  a Fund is required to  recognize as
income  for each  taxable  year its net  unrealized  gains and losses on futures
contracts as of the end of the year as well as those  actually  realized  during
the year.  Any gain or loss  recognized  with  respect to a futures  contract is
considered to be 60% long term and 40% short term, without regard to the holding
period of the  contract.  In the case of a futures  transaction  classified as a
"mixed  straddle," the  recognition of losses may be deferred to a later taxable
year. The federal income tax treatment of gains or losses from  transactions  in
options on futures is unclear.

         In order for a Fund to  continue  to  qualify  for  federal  income tax
treatment as a regulated  investment  company,  at least 90% of its gross income
for a taxable year must be derived from qualifying income. Any net gain realized
from the closing out of futures contracts,  for purposes of the 90% requirement,
will be  qualifying  income.  In addition,  gains  realized on the sale or other
disposition  of  securities  held for less than three  months must be limited to
less  than 30% of a  Fund's  annual  gross  income.  The  1986  Tax Act  added a
provision   which   effectively   treats  both  positions  in  certain   hedging
transactions as a single transaction for the purpose of the 30% requirement. The
provision  provides that, in the case of any "designated  hedge,"  increases and
decreases  in the value of  positions  of the  hedge  are to be  netted  for the
purposes of the 30% requirement.  However,  in certain  situations,  in order to
avoid  realizing a gain within a three month  period,  a Fund may be required to
defer the closing out of a contract  beyond the time when it would  otherwise be
advantageous to do so.

RISKS OF FUTURES CONTRACTS

         Financial  futures  contracts  prices are volatile and are  influenced,
among other things, by changes in stock prices,  market  conditions,  prevailing
interest  rates and  anticipation  of future stock prices,  market  movements or
interest rate changes, all of which in turn are affected by economic conditions,
such as government  fiscal and monetary  policies and actions,  and national and
international political and economic events.

         At best, the correlation between changes in prices of futures contracts
and of the  securities  being  hedged  can be only  approximate.  The  degree of
imperfection of correlation  depends upon  circumstances,  such as variations in
speculative  market demand for futures  contracts and for securities,  including
technical  influences  in futures  contracts  trading;  differences  between the
securities being hedged and the financial instruments and indexes underlying the
standard futures contracts  available for trading,  in such respects as interest
rate levels,  maturities  and  creditworthiness  of issuers,  or  identities  of
securities  comprising the index and those in a Fund's  portfolio.  In addition,
futures contract  transactions involve the remote risk that a party be unable to
fulfill its obligations and that the amount of the obligation will be beyond the
ability of the clearing broker to satisfy.  A decision of whether,  when and how
to hedge involves the exercise of skill and judgment,  and even a well conceived
hedge  may be  unsuccessful  to  some  degree  because  of  market  behavior  or
unexpected interest rate trends.

         Because of the low margin deposits  required,  futures trading involves
an extremely  high degree of  leverage.  As a result,  a relatively  small price
movement in a futures contract may result in immediate and substantial  loss, as
well as gain, to the investor.  For example, if at the time of purchase,  10% of
the value of the futures  contract is deposited as margin, a 10% decrease in the
value  of the  futures  contract  would  result  in a total  loss of the  margin
deposit,  before any deduction for the  transaction  costs,  if the account were
then closed out, and a 15% decrease  would result in a loss equal to 150% of the
original  margin  deposit.  Thus,  a purchase or sale of a futures  contract may
result  in losses in excess of the  amount  invested  in the  futures  contract.
However, a Fund would presumably have sustained comparable losses if, instead of
entering into the futures contract,  it had invested in the underlying financial
instrument.  Furthermore,  in order  to be  certain  that a Fund has  sufficient
assets  to  satisfy  its  obligations  under a futures  contract,  the Fund will
establish a segregated  account in connection  with its futures  contracts which
will hold cash or cash  equivalents  equal in value to the current  value of the
underlying instruments or indices less the margins on deposit.

         Most U.S. futures  exchanges limit the amount of fluctuation  permitted
in  futures  contract  prices  during a single  trading  day.  The  daily  limit
establishes  the maximum  amount that the price of a futures  contract  may vary
either  up or down  from the  previous  day's  settlement  price at the end of a
trading  session.  Once the daily limit has been reached in a particular type of
contract,  no trades may be made on that day at a price  beyond that limit.  The
daily limit  governs only price  movement  during a  particular  trading day and
therefore  does not limit  potential  losses  because  the limit may prevent the
liquidation of unfavorable positions.  Futures contract prices have occasionally
moved to the daily limit for several  consecutive trading days with little or no
trading,   thereby  preventing  prompt  liquidation  of  futures  positions  and
subjecting some futures traders to substantial losses.

RISKS OF OPTIONS ON FUTURES CONTRACTS

         In  addition  to  the  risks  described  above  for  financial  futures
contracts,  there are  several  special  risks  relating  to  options on futures
contracts. The ability to establish and close out positions on such options will
be subject to the  development  and  maintenance of a liquid  secondary  market.
There  is no  assurance  that a  liquid  secondary  market  will  exist  for any
particular  contract or at any particular time. A Fund will not purchase options
on any futures  contract  unless and until it believes  that the market for such
options  has  developed  sufficiently  that the  risks in  connection  with such
options are not greater than the risks in connection with the futures contracts.
Compared  to the use of  futures  contracts,  the  purchase  of  options on such
futures  involves less  potential  risk to a Fund because the maximum  amount at
risk is the premium  paid for the options  (plus  transaction  costs).  However,
there may be circumstances when the use of an option on a futures contract would
result in a loss to a Fund, even though the use of a futures contract would not,
such as when there is no movement in the level of the futures contract.

Keystone State Tax Free Fund 

NOTES TO FINANCIAL STATEMENTS 

1. Significant Accounting Policies 

Keystone State Tax Free Fund (formerly Keystone America State Tax Free Fund) 
("FUND") was formed as a Massachusetts business trust on September 13, 1990. 
Keystone Investment Management Company (formerly Keystone Custodian Funds, 
Inc.) ("Keystone") is the Investment Adviser and Manager. The FUND currently 
offers shares of five separate series evidencing interests in different 
portfolios of securities: the Keystone Florida Tax Free Fund (formerly 
Keystone America Florida Tax Free Fund) ("Florida Fund"), which was 
established on September 19, 1990 and had no operations prior to December 28, 
1990; the Keystone Massachusetts Tax Free Fund (formerly Keystone America 
Massachusetts Tax Free Fund) ("Massachusetts Fund"), and the Keystone New 
York Insured Tax Free Fund (formerly Keystone America New York Insured Tax 
Free Fund) ("New York Fund"), which were established February 21, 1992 and 
had no operations prior to February 4, 1994; the Keystone Pennsylvania Tax 
Free Fund (formerly Keystone America Pennsylvania Tax Free Fund) 
("Pennsylvania Fund"), which was established September 19, 1989 and had no 
operations prior to December 27, 1990; and the Keystone Texas Tax Free Fund 
(formerly Keystone America Texas Tax Free Fund) ("Texas Fund"), which was 
established on February 21, 1992 and had no operations prior to March 2, 1992 
(together the "Funds" and each individually a "Fund"). The FUND is registered 
under the Investment Company Act of 1940 as an open-end investment company 
and each of the Funds is registered as a nondiversified fund. 

   Each Fund issues Class A, Class B and Class C shares. Class A shares are 
sold subject to a maximum sales charge of 4.75% payable at the time of 
purchase. Class B shares are sold subject to a contingent deferred sales 
charge payable upon redemption within three calendar years after the year of 
purchase. Class C shares are sold subject to a contingent deferred sales 
charge payable upon redemption within one year of purchase. Class C shares 
are available only through dealers who have entered into special distribution 
agreements with Keystone Investment Distributors Company (formerly Keystone 
Distributors, Inc.) ("KIDC"), the FUND's principal underwriter. 

   Keystone is a wholly-owned subsidiary of Keystone Investments, Inc. 
(formerly Keystone Group, Inc.) ("KII"), a Delaware corporation. KII is 
privately owned by an investor group consisting of members of current 
management. Keystone Investor Resource Center, Inc. ("KIRC"), a wholly-owned 
subsidiary of Keystone, is the FUND's transfer agent. 

   The following is a summary of significant accounting policies consistently 
followed by the FUND, in conformity with generally accepted accounting 
principles. 

A. Tax-exempt bonds are stated on the basis of valuations provided by a 
pricing service, approved by the Board of Trustees, that 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. Non-tax-exempt securities for which market 
quotations are readily available are valued at the price quoted which, in the 
opinion of the Board of Trustees or their representative, most nearly 
represents their market value. Short-term investments which are purchased 
with maturities of sixty days or less are valued at amortized cost (original 
cost as adjusted for amortization of premium or accretion of discount) which 
when combined with accrued interest approximates market. Short term 
investments maturing in more than sixty days for which market quotations are 
readily available are valued at current market value. Short-term investments 
maturing in more than sixty days when purchased which are held on the 
sixtieth day prior to maturity are valued at amortized cost (market value on 
the sixtieth day adjusted for amorti- 

<PAGE> 

zation of premium or accretion of discount) which when combined with accrued 
interest approximates market. All other securities and other assets are 
valued at fair value as determined in good faith using methods prescribed by 
the Board of Trustees. 

   Each Fund enters into currency and other financial futures contracts as a 
hedge against changes in interest or currency exchange rates. A futures 
contract is an agreement between two parties to buy and sell a specific 
amount of a commodity, security, financial instrument, or, in the case of a 
stock index, cash at a set price on a future date. Upon entering into a 
futures contract the Fund is required to deposit with a broker an amount 
("initial margin") equal to a certain percentage of the purchase price 
indicated in the futures contract. Subsequent payments ("variation margin") 
are made or received by the Fund each day, as the value of the underlying 
instrument or index fluctuates, and are recorded for book purposes as 
unrealized gains or losses by the Fund. For federal tax purposes, any futures 
contracts which remain open at fiscal year end are marked-to-market and the 
resultant net gain or loss is included in the Fund's taxable income. In 
addition to market risk, the Fund is subject to the credit risk that the 
other party will not complete the obligations of the contract. 

B. When-issued or delayed delivery transactions arise when securities or 
currencies are purchased or sold by a Fund with payment and delivery taking 
place in the future in order to secure what is considered to be an 
advantageous price and yield to the Fund at the time of entering into the 
transaction. A separate account of liquid assets equal to the value of such 
purchase commitments will be maintained until payment is made. When-issued 
and delayed agreements are subject to risks from changes in value based upon 
changes in the level of interest rates and other market factors, both before 
and after delivery. 

C. Securities transactions are accounted for no later than one business day 
after the trade date. Realized gains and losses are recorded on the 
identified cost basis. Interest income is recorded on the accrual basis. 

D. Each Fund has qualified, and intends to qualify in the future, as a 
regulated investment company under the Internal Revenue Code of 1986, as 
amended ("Internal Revenue Code"). Thus, each Fund expects to be relieved of 
any federal income tax liability by distributing all of its net taxable 
investment income and net taxable capital gains, if any, to its shareholders. 
The tax-exempt interest portion of each dividend is declared uniformly based 
on the ratio of each Fund's tax-exempt and taxable income for the entire 
year. Each Fund intends to avoid excise tax liability by making the required 
distributions under the Internal Revenue Code. 

E. Organization expenses are being amortized to operations over a five-year 
period on a straight-line basis. In the event any of the initial shares are 
redeemed by any holder thereof during the five-year amortization period, 
redemption proceeds will be reduced by any unamortized organization expenses 
in the same proportion as the number of initial shares being redeemed bears 
to the number of initial shares outstanding at the time of redemption. 

2. Capital Share Transactions 

The Trust agreement authorizes the issuance of an unlimited number of shares 
of beneficial interest without par value. Transactions in shares of the FUND 
were as follows:

   Each Fund bears some of the costs of selling its shares under a 
Distribution Plan adopted with respect to its Class A, Class B, and Class C 
shares pursuant to Rule 12b-1 under the Investment Company Act of 1940. Under 
the Distribution Plan, the Fund pays KIDC, the principal underwriter and a 
wholly-owned subsidiary of Keystone, amounts which in total may not exceed 
the Distribution Plan maximum. 

   Each Class A Distribution Plan provides for payments which are currently 
limited to 0.15% annually of the average daily net asset value of Class A 
shares to pay expenses of the distribution of Class A shares. Amounts paid by 
each Fund to KIDC under the Class A Distribution Plan are currently used to 
pay others such as brokers or dealers, service fees at an annual rate of 
0.15% of the average net asset value of the shares sold by such others and 
remaining outstanding on the books of the Funds for specified periods. 

   Each Class B Distribution Plan provides for payments at an annual rate of 
0.90% of the average daily net asset value of Class B shares to pay expenses 
of the distribution of Class B shares. Amounts paid by each Fund under the 
Class B Distribution Plan are currently used to pay others (dealers) (i) a 
commission at the time of purchase normally equal to 3.00% of the value of 
each share sold; and/or (ii) service fees currently at an annual rate of 
0.15% of the average net asset value of shares sold by such others and 
remaining outstanding on the books of the Funds for specified periods. 

   Each Class C Distribution Plan provides for payments at an annual rate of 
up to 0.90% of the average daily net asset value of Class C shares to pay 
expenses of the distribution of Class C shares. Amounts paid by each Fund 
under the Class C Distribution Plan are currently used to pay others 
(dealers) (i) a commission at the time of purchase normally equal to 1.00% of 
the value of each share sold; and (ii) beginning approximately fifteen months 
after purchase a commission at an annual rate of 0.75% (subject to applicable 
limitations imposed by the rules of the National Association of Securities 
Dealers, Inc. ("NASD")) plus service fees at an annual rate of 0.15% of the 
average net asset value of each share sold by such others and 
<PAGE> 

remaining outstanding on the books of the Funds for specified periods. 

   Each of the Distribution Plans may be terminated at any time by vote of 
the Independent Trustees or by vote of a majority of the outstanding voting 
shares of the respective class. However, after the termination of any of the 
Distribution Plans, at the discretion of the Board of Trustees, payments to 
KIDC may continue as compensation for its services which had been earned 
while the distribution Plan was in effect. 

   For the year ended March 31, 1995, the Florida Fund paid KIDC $66,246, 
$345,221 and $140,405, the Massachusetts Fund paid KIDC $1,829, $40,387 and 
$15,014, the New York Fund paid KIDC $3,025, $70,227, and $15,895, the 
Pennsylvania Fund paid KIDC $44,697, $244,404 and $81,781, and the Texas Fund 
paid KIDC $2,847, $18,613 and $5,377, respectively, pursuant to each Fund's 
Class A, Class B, and Class C Distribution Plans. 

   Under a Rule of the NASD, the maximum uncollected amounts for which KIDC 
may seek payment from the FUND under its Class B Distribution Plans are 
$3,196,058, $384,672, $728,940, $1,923,455, and $145,495, respectively, for 
the Florida Fund, the Massachusetts Fund, the New York Fund, the Pennsylvania 
Fund and the Texas Fund as of March 31, 1995. The maximum uncollected amounts 
for which KIDC may seek payment from the FUND under its Class C Distribution 
Plans are $1,218,232, $118,845, $176,106, $743,501, and $58,326, 
respectively, for the Florida Fund, the Massachusetts Fund, the New York

4. Investment Management and Transactions with Affiliates 

Under the terms of the Investment Management Agreement between Keystone and 
the FUND, dated November 29, 1990, Keystone provides investment management 
and administrative services to the FUND and its Funds. In return, Keystone is 
paid a management fee computed and paid daily. The management fee is 
calculated by applying percentage rates, which start at 0.55% and decline, as 
net assets increase, to 0.25% per annum, to the net asset value of each Fund. 

   During the year ended March 31, 1995, the Florida Fund, the Massachusetts 
Fund, the New York Fund, the Pennsylvania Fund and the Texas Fund paid or 
accrued to Keystone investment management and administrative services fees of 
$515,205, $43,636, $63,808, $357,852 and $25,402, respectively, which 
represented 0.52%, 0.55%, 0.55%, 0.54%, and 0.55%, respectively, of the 
average net assets of the Funds on an annualized basis. 

   During the year ended March 31, 1995, the Florida Fund, the Massachusetts 
Fund, the New York Fund, the Pennsylvania Fund and the Texas Fund paid or 
accrued to KII $13,052, $17,498, $17,698, $20,909 and $13,870, respectively, 
for certain accounting and printing services and to KIRC $116,367, $15,568, 
$25,831, $108,073, and $6,215, respectively, for transfer agent fees. 

   Keystone has voluntarily agreed to limit all expenses incurred including 
management fee of the Class A Shares of the Florida Fund, the Pennsylvania 
Fund and the Texas Fund to 0.75% of average daily net assets and has limited 
annual expenses of the Class B Shares and Class C Shares to 1.50% of average 
daily net asset value. 

   Keystone voluntarily limited the expenses, including the management fee, 
of the Class A Shares of the Massachusetts Fund and the New York Fund to 
0.35% until August 15, 1994, after which the expense limitation is being 
increased by 0.10% every three months until May 15, 1995 when expenses will 
be limited to 0.75% until December 31, 1995. Expenses of Class B Shares and 
Class C Shares of those Funds were limited to 1.10% until August 15, 1994, 
after which the expense limitations are being similarly increased until May 
15, 1995 when expenses will be limited to 1.50% until December 31, 1995. 
Keystone will not be required to make such reimbursement to an extent which 
would result in a Fund's inability to qualify as a regulated investment 
company under the provisions of the Internal Revenue Code. In accordance with 
this voluntary expense limitation, Keystone reimbursed the Florida Fund, the 
Massachusetts Fund, the New York Fund, the Pennsylvania Fund and the Texas 
Fund (i) $89,179, $26,169, $22,366, $91,489 and $35,517, respectively, with 
respect to each Fund's Class A Shares, (ii) $68,953, $64,511, $85,602, 
$81,415 and $38,490, respectively, with respect to each Fund's Class B 
Shares; and (iii) $31,739, $24,181, $18,786, $27,453 and $10,643, 
respectively, with respect to each Fund's Class C Shares. Keystone does not 
intend to seek repayment of these amounts. 
<PAGE> 

Certain officers and/or Directors of Keystone are also officers and/or 
Trustees of the FUND. Officers of Keystone and affiliated Trustees receive no 
compensation directly from the FUND. Currently, the Independent Trustees of 
the FUND receive no compensation for their services. 

5. Distributions to Shareholders 

Each Fund intends to declare dividends from net investment income daily and 
distribute to its shareholders such dividends monthly and to declare and 
distribute all net realized long-term capital gains, if any, at least 
annually. Distributions are determined in accordance with income tax 
regulations. Distributions from tax basis net investment income and net 
capital gains can exceed book basis net investment income and net capital 
gains.

Keystone State Tax Free Fund 

Independent Auditors' Report 

The Trustees and Shareholders of 
Keystone State Tax Free Fund (formerly Keystone America State Tax Free Fund) 

We have audited the financial statements, including the schedules of 
investments and the financial highlights for the portfolios of Keystone State 
Tax Free Fund ("the Funds") as listed in the accompanying index to financial 
statements. These financial statements and financial highlights are the 
responsibility of the Funds' 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 March 31, 1995 by correspondence with the custodian 
and brokers. 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, the financial statements and financial highlights referred to 
above present fairly, in all material respects, the financial position of the 
portfolios of Keystone State Tax Free Fund as of March 31, 1995, the results 
of their operations, the changes in their net assets and the financial 
highlights for each of the periods specified in the index to financial 
statements in conformity with generally accepted accounting principles.
