PROSPECTUS MARCH 31, 1995
    

     Keystone  America State Tax Free Fund -- Series II (the "FUND") is a mutual
fund that  currently  consists  of two  separate  series  of  shares  evidencing
interests in different portfolios of securities ("Funds"):  the Keystone America
California  Insured Tax Free Fund  ("California  Insured Fund") and the Keystone
America Missouri Tax Free Fund ("Missouri Tax Free Fund").

     Each of the Funds seeks the highest  possible  current  income  exempt from
federal income taxes,  while  preserving  capital.  In addition,  each Fund also
seeks to provide a maximum  level of income to its  shareholders  that is exempt
from the personal income taxes of the shareholders' state of residence.

     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. The Missouri Tax
Free Fund also seeks to hold securities  exempt from Missouri  personal property
taxes. At least 80% of the municipal securities in the California 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.

<FN>
- ---------
<F1>  Class B Shares  convert tax free to Class A shares  after  seven  calendar
      years.
   
<F2> Class C shares are  available  only  through  dealers who have entered into
     special distribution agreements with Keystone Distributors, Inc. the Funds'
     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 are not
      subject to a sales  charge,  but may be subject to a  contingent  deferred
      sales charge of 0.25%. See "Contingent Deferred Sales Charge and Waiver of
      Sales Charges" for an explanation of the charge.
<F5>  There is no fee for exchange orders received by the Funds directly from an
      individual shareholder 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  November 30, 1995
     after giving effect to the reimbursement by Keystone  Custodian Funds, Inc.
     ("Keystone")  of expenses in  accordance  with  certain  voluntary  expense
     limitations.  Currently, Keystone has voluntarily limited expenses of Class
     A shares to 0.65% of average  daily net assets of such class  until May 15,
     1995.  Thereafter,  Keystone has  voluntarily  limited  Class A expenses to
     0.75%  until  December  31,  1995.   Similarly,   Keystone   currently  has
     voluntarily  limited  expenses  of Class B and C shares to 1.40% of average
     daily net  assets  of each  such  class  until  May 15,  1995.  Thereafter,
     Keystone has voluntarily limited expenses of each such class to 1.50% until
     December  31,  1995.  Keystone is under no  obligation  to  maintain  these
     limits. Absent these voluntary expense limitations,  expense ratios for the
     California Insured Fund's fiscal year ending November 30, 1995 for Class A,
     B and C shares are projected to be  approximately  1.54%,  2.29% and 2.29%,
     respectively.
    
<F7>  The Class B and Class C  Distribution  Plans  provide  for  payments at an
      annual rate of up to 1.00% of the average daily net asset value of Class B
      and Class C shares; however, such payments are currently limited to 0.90%.
      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  returns 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 December  15, 1993.  The FUND is one of  twenty-nine  funds  managed or
advised by Keystone  Custodian Funds, Inc.  ("Keystone"),  the FUND's investment
adviser. The FUND currently consists of two separate series evidencing interests
in different portfolios of securities:  the California Insured Fund and Missouri
Tax Free Fund. 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,
which  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   promisory  notes  issued  by
municipalities to meet short-term credit needs.

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

  The  California  Insured  Fund  invests  only 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.

  As more fully  discussed below in the section  entitled  "Insurance," at least
80% of the municipal  securities in the  investment  portfolio of the California
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 California tax treatment and the factors affecting
investment in California municipal obligations, see Exhibit A.

MISSOURI TAX FREE FUND
  Under ordinary circumstances,  the Missouri Tax Free Fund invests at least 80%
of its assets in  securities,  the  interest  from which is exempt from  federal
taxes and Missouri  state income  taxes,  as well as being exempt from  Missouri
personal  property taxes. The Missouri Tax Free Fund invests in debt obligations
of the State of Missouri and its political subdivisions,  agencies,  authorities
and  instrumentalities and debt obligations of other qualifying issuers, such as
U.S. territories.


  The Missouri  Tax Free 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 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. 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 Missouri tax treatment and the factors  affecting
investment in Missouri 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.

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


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 in  California  or income or personal
property tax in Missouri.  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.  Neither  Fund is expected to enter
into repurchase agreements in the ordinary course of its 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 instruments," 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  California
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,"  a  "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 California Insured Fund's portfolio. Similarly, because
the net asset value of the  California  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  California  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 California 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 California 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  California
Insured Fund.  Premium rates for each issue of securities  covered by the policy
are  fixed  for the life of the  California  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 California  Insured Fund's average annual  expenses.  Premiums are paid from
the  California  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 California  Insured Fund
and  covered  by the  policy,  except  for  nonpayment  of  premiums.

SECONDARY INSURANCE POLICIES
  The California  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 ordinarily  continue in force so long as the securities
so insured are outstanding.  Secondary Insurance will likely be purchased by the
California 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
California  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 California 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, as defined in the Investment Company Act
of 1940 ("1940 Act"), of the affected Fund's outstanding 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
  Each Fund has adopted the fundamental restrictions summarized below, which may
not be changed without the vote of a majority of such Fund's outstanding shares.
These   restrictions   and  certain  other   fundamental   and   non-fundamental
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 each Fund may invest  more than 25% of its  assets in  industrial
development bonds; and

  (2) 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.


  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  fifth  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
  Investing in a Fund  involves  the risk common to  investing in any  security,
i.e.,  net asset  value will  fluctuate  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 Missouri  Tax Free 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,  also  commonly  known as "junk 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 Missouri Tax Free 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 bonds will not exceed 20% of the Missouri Tax
Free 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 Missouri Tax Free
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 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 Missouri Tax Free 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 Missouri Tax Free 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:  money  market
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.  All dividends and
distributions will be payable in shares or, at the option of the shareholder, 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.


  Currently,  commissions  paid by the Funds on new  sales of  shares  under the
Funds'  Distribution Plans (see "Distribution  Plans") and deferred sales charge
receipts are treated as capital charges and capital  credits,  respectively,  in
determining  net  investment  income for tax purposes.  For financial  statement
purposes, however, these expenses and receipts are treated as operating expenses
and expense offsets. As a result, the amount of dividend  distributions required
to satisfy the  requirements of the Code might exceed net investment  income for
financial statement  purposes,  resulting in a portion of such dividends being a
distribution  in  excess  of  net  investment  income  for  financial  statement
purposes. Total investment return is equally affected by both treatments.

  Recently,  the  Internal  Revenue  Service  ("IRS")  issued a ruling that will
require the FUND,  effective April 1, 1995, to treat its 12b-1 fees as operating
expenses, instead of as capital charges. The Funds intend to comply with the IRS
ruling by that date. As a result,  after April 1, 1995,  dividend  distributions
are no longer expected to exceed net investment  income for financial  statement
purposes. Total investment return will not be affected.


  Differences in the operation of the  Distribution  Plan adopted by the Class A
shares of each Fund from that of the Class B and Class C Distribution Plans will
cause a variation in the net asset values of the respective classes of shares.

  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 distributions were 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 fiscal  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 must be  allocated
between  such  securities  and the put 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.  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.


  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 situations.

  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.

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 Group, Inc.
("Keystone Group"), 200 Berkeley Street, Boston, Massachusetts 02116-5034.

  Keystone  Group is a  corporation  predominantly  owned by current  and former
members of  management  of Keystone and its  affiliates.  The shares of Keystone
Group  common stock  beneficially  owned by  management  are held in a number of
voting  trusts,  the trustees of which are George S. Bissell,  Albert H. Elfner,
III,  Edward F.  Godfrey and Ralph J.  Spuehler,  Jr.  Keystone  Group  provides
accounting,  bookkeeping,  legal,  personnel and general  corporate  services to
Keystone, its affiliates and the Keystone Group of Mutual Funds.

  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 currently offered pays Keystone a fee for its services at the annual
rate set forth below:
                                                                       Aggregate
                                                                 Net Asset Value

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

  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 the vote of
a majority of the shares of such Fund.  The Advisory  Agreement  will  terminate
automatically upon its assignment.

  Keystone  and the  FUND  have  each  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.

  During the period  February 1, 1994  (Commencement  of Operations) to November
30,  1994,  the  California  Insured Fund and the Missouri Tax Free Fund paid or
accrued to Keystone  investment  management and administrative  services fees of
$49,627 and $47,930, respectively.

   
  During the period  February 1, 1994  (Commencement  of Operations) to November
30,  1994,  the  California  Insured Fund and the Missouri Tax Free Fund paid or
accrued to Keystone Investor Resource Center, Inc. ("KIRC"), the FUND's transfer
and  dividend  disbursing  agent,  $16,901,  and  $25,820,   respectively,   for
shareholder  services.  During  the period  February  1, 1994  (Commencement  of
Operations) to November 30, 1994,  the California  Insured Fund and the Missouri
Tax Free Fund paid or accrued to KGI  $11,753,  and  $10,954,  respectively,  as
reimbursement for certain accounting services.

  Currently,  Keystone has voluntarily limited the expenses of Class A shares of
each Fund to 0.65% of the  average  daily net assets of such class until May 15,
1995. Thereafter, Keystone has currently voluntarily limited Class A expenses to
0.75% until  December  31,  1995.  Keystone has  currently  voluntarily  limited
expenses  of Class B and C shares to 1.40% of the  average  daily net  assets of
each  such  class  until  May  15,  1995.  Thereafter,  Keystone  has  currently
voluntarily  limited the  expenses of such  classes to 1.50% until  December 31,
1995.  Thereafter,  a  redetermination  of whether  to  continue  these  expense
limitations  and,  if so,  at what  rate,  will be  made.  Keystone  will not be
required to make such  reimbursement  to the extent it would  result in a Fund's
inability to qualify as a regulated  investment  company under the provisions of
the Code. In accordance with expense limitations in effect for the fiscal period
ended November 30, 1994, Keystone reimbursed the California Insured Fund and the
Missouri  Tax Free Fund (1) $23,507 and $12,109,  respectively,  with respect to
each Fund's Class A shares; (2) $81,857 and $91,759, respectively,  with respect
to each Fund's Class B shares;  and (3) $4,427 and $10,208,  respectively,  with
respect to each Fund's Class C shares.
    

PORTFOLIO MANAGER
  Betsy Blacher,  a Keystone Vice President and Senior  Portfolio  Manager,  has
been the FUND's portfolio  manager since the FUND's inception and is responsible
for the day-to-day  management of the  California  Insured Fund. Ms. Blacher has
more than 15 years of investment experience.

  Daniel A  Rabasco,  a  Keystone  Vice  President  and  Portfolio  Manager,  is
responsible  for the  day-to-day  management of the Missouri Tax Free Fund.  Mr.
Rabasco has more than 8 years of investment experience.

SECURITIES TRANSACTIONS
  Under  policies   established  by  the  Board  ofTrustees,   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 period ended November 30, 1994, the portfolio turnover rate for
the California  Insured Fund was 104%. For the same period the turnover rate for
the  Missouri  Tax Free  Fund was  25%.  High  portfolio  turnover  may  involve
correspondingly greater brokerage commissions and other transaction costs, which
would be borne directly by a Fund, as well as additional  gains and/or losses to
shareholders. For additional information about brokerage and distributions,  see
the statement of additional information to this prospectus.
    

HOW TO BUY SHARES
  Shares of each Fund may be purchased from any broker-dealer that has a selling
agreement  with  Keystone  Distributors,  Inc.  ("KDI"),  the  FUND's  principal
underwriter.  KDI, a  wholly-owned  subsidiary  of  Keystone,  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.  Or you may
telephone  1-800-343-2898  to obtain  the  number of an account to which you can
wire or  electronically  transfer  funds  and then send in a  completed  account
application. Subsequent investments in a Fund's 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 KDI  (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 KDI 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 KDI 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
  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 sales  charge when they are  redeemed  (except  that
shares  sold in a single  purchase in excess of  $1,000,000  without a front end
sales  charge  will be subject to a  contingent  deferred  sales  charge for one
year).

CLASS B SHARES -- BACK END LOAD OPTION
  Class B shares are sold without a sales  charge at the time of  purchase,  but
are subject to a deferred sales charge if they are redeemed  during the calendar
year of purchase or within  three  calendar  years  after the  calendar  year of
purchase. Class B shares will automatically convert to Class A shares at the end
of seven calendar years after purchase.

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 KDI.

   
  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 their respective  classes.  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 Funds 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.
                  -----------------------------------------

  charge of 0.25%.  See  "Contingent  Deferred  Sales Charge and Waiver of Sales
  Charges."
                 -------------------------------------------


   
  The sales charge is paid to KDI, 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 outstanding shares of Class A maintained outstanding on the books
of the FUND for specified period.
    

  Upon  written  notice to dealers with whom it has dealer  agreements,  KDI 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 to be included in a managed fee based  program  ("wrap  account")
through broker dealers who have entered into special agreements with KDI.

   
  Beginning  January 1, 1995 through June 30, 1995 ("offering  period") and upon
prior notification to KDI, 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 KDI 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.
    

  In addition,  upon prior  notification to KDI, Class A shares may be purchased
at net asset  value by clients of  registerd  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 KDI 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.

   With  certain  exceptions,  purchases  of Class A  shares  in the  amount  of
$1,000,000  or more on which no sales  charge has been paid will be subject to a
contingent  deferred sales charge of 0.25% upon  redemption  during the one year
period  commencing  on the  date  the  shares  were  originally  purchased.  The
contingent  deferred sales charge is retained by KDI. See  "Contingent  Deferred
Sales Charges and Waiver of Sales Charges" below.

CLASS A DISTRIBUTION PLAN
  Each Fund has adopted a  Distribution  Plan with respect to its Class A shares
(the "Class A  Distribution  Plan"),  which  provides  for  payments  (currently
limited  to 0.15%  annually  of the  average  daily net  asset  value of Class A
shares) to pay  expenses  associated  with the  distribution  of Class A shares.
Amounts  paid by each  Fund to KDI  under  the  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 daily net asset value of Class A shares maintained by
such others  outstanding on the books of a Fund for specified  periods.

CLASS B SHARES
  Class B shares are  offered  at net asset  value,  without  an  initial  sales
charge.  With certain  exceptions,  a Fund may impose 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. If imposed, the deferred sales
charge  is  deducted  from the  redemption  proceeds  otherwise  payable  to the
shareholder.  The deferred sales charge is retained by KDI.  Amounts received by
KDI under the Class B  Distribution  Plan are reduced by deferred  sales charges
retained by KDI.  See  "Contingent  Deferred  Sales  Charges and Waiver of Sales
Charges" below.

  Class B shares that have been  outstanding  during seven  calendar  years 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.  (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 PLAN
  Each Fund has adopted a  Distribution  Plan with respect to its Class B shares
(the "Class B Distribution  Plan") that provides for  expenditures  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  Plan are currently made to KDI
(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 KDI under (1) and (2) in the  aggregate  may not  exceed  the annual
limitation  referred  to above.  KDI  generally  reallows to brokers or others a
commission  equal to 3% of the price  paid for each  Class B share  sold and the
shareholder service fee, which is paid at the rate of 0.15% per annum of the net
asset value of Class B shares  maintained by the  recipients  outstanding on the
books of the Fund for specified periods. See "Distribution Plans" below.
    

CLASS C SHARES
  Class C shares are offered only through dealers who have special  distribution
agreements  with KDI. 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 KDI. See
"Contingent  Deferred Sales Charges 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 KDI
(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 KDI under (1) and (2) in the  aggregate  may not  exceed  the annual
limitation  referred  to above.  KDI  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 the NASD
rule -- see "Distribution Plans") plus service fees which are paid 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 cost 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) Class C shares and certain Class A shares held for more than
one year from the date of purchase;  or (4) Class B shares held during more than
four consecutive calendar years. 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 KDI; and to a bank or trust  company  acting as a trustee for a
single account.

  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 5912 years old; (4)
involuntary  redemptions of accounts having an aggregate net asset value of less
than $1,000; or (5) automatic  withdrawals under an automatic withdrawal plan of
up to 112% per month of the shareholder's initial account balance.

ARRANGEMENTS WITH BROKER-DEALERS AND OTHERS
  From  time  to  time,  KDI  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.
KDI  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.

  KDI 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
KDI. 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 up to 0.25% of the
value of shares sold by such dealer.

  KDI 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
  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. Payments under the Class A Distribution  Plans
are  currently  limited to up to 0.15%  annually of the average  daily net asset
value  of  Class A  shares.  The  Class B  Distribution  Plans  and the  Class C
Distribution  Plans  provide for the payment at an annual rate of up to 1.00% of
the  average  daily  net  asset  value  of Class B shares  and  Class C  shares,
respectively, although payments under the Class B and Class C Distribution Plans
are currently limited to 0.90%.

  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 KDI).

  KDI 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 KDI from a Fund. KDI 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,
KDI  will  ask the  Independent  Trustees  to take  whatever  action  they  deem
appropriate under the circumstances with respect to payment of such amounts.

  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.

   
  Unreimbursed  distribution  expenses at  November  30, 1994 for Class B shares
were  $784,751  (6.87% of Class B net assets at November  30, 1994) and $862,192
(6.88% of Class B net assets at November  30, 1994) for the  California  Insured
Fund and the Missouri Tax Free Fund, respectively.
    

  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.  The redemption value of a Fund's share is its net asset value
per share  adjusted  for  fractions  of a cent and may be more or less than your
cost  depending  upon  changes  in the  value of a Fund's  portfolio  securities
between  purchase and redemption.  In order to redeem by telephone you must have
completed the authorization in your account application.

  At various times the FUND may be requested to redeem a Fund's shares for which
it has not yet received good payment.  In such a case, the FUND will mail,  wire
or send by EFT 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 either with a certified check or bank wire of funds or EFT.  Although the
mailing of a redemption check or wiring or sending by EFT 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 the 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
payment  of a  redemption  has been  delayed,  the  check  will be mailed or the
proceeds wired or sent EFT 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 will be made within seven days thereafter except
as discussed herein.

  You may also redeem your shares through  broker-dealers.  KDI, 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 KDI receives
the order. If KDI has received proper documentation,  it will pay the redemption
proceeds to the  broker-dealer  placing the order within seven days  thereafter.
KDI 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
BANK 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. However, you must complete the
Telephone   Redemption  section  of  the  application  to  enjoy  the  telephone
redemption privileges.

  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 above.

SMALL ACCOUNTS
  Because of 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.

REDEMPTION OF CERTAIN CLASS A SHARES
  Certain  purchases of Class A Shares in the amount of  $1,000,000  or more, on
which no  initial  sales  charge  has been paid,  are  subject  to a  contingent
deferred  sales  charge of 0.25%.  See the  section  entitled  "Class A Shares."

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  KDI  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 KDI 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  Class B shares  of other  Keystone
   America Funds and 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 where the original purchase was for $1,000,000 or more and
no sales charge was paid,

   (2) Class B shares that have been held for less than four years, 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.  However,  you must complete the Telephone Exchanges section
of the application to enjoy the telephone exchange privileges.  Shares purchased
by check are eligible for exchange after 15 days. There is a $10.00 fee for each
exchange;  however, there is no exchange fee for exchange orders received by the
FUND directly from an individual  shareholder  over KARL.  The FUND reserves the
right,  after providing  shareholders  with any required  notice,  to change the
terms of or to terminate this exchange offer,  including the right to change the
service charge for any exchange.

  Orders to  exchange  shares of a Fund for  shares of KLT will be  executed  by
redeeming the shares of the Fund and  purchasing  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 KDI 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 of your
Keystone America Funds automatically  invested to purchase Class A 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.

OTHER SERVICES
  Under  certain  circumstances  you may,  within  30 days  after a  redemption,
reinstate your account 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 total  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., CDS-Weisenberger and Value
Line or other industry publications.

FUND SHARES
  The FUND currently issues shares of two separate series  evidencing  interests
in different portfolio securities. Each Fund 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 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  forthe  FUND's  obligations  and provides  indemnification  from FUND
assets for any shareholder held personally liable for the FUND's obligations.

ADDITIONAL INFORMATION
  KIRC, located at 101 Main Street,  Cambridge,  Massachusetts  02142-1519, is a
wholly-owned subsidiary of Keystone. As previously mentioned, KIRC serves as the
FUND's transfer agent and dividend disbursing agent.

  When the FUND  determines  from its records  that more than one account in the
FUND is registered in the name of a shareholder or shareholders  having the same
address,  upon notice to those  shareholders,  the FUND intends,  when an annual
report or a semi-annual report of the FUND is required to be furnished,  to mail
one copy of such report to that address.

  Except as  otherwise  stated in this  prospectus  or required by law, the FUND
reserves  the right to change the terms of the offer  stated in this  prospectus
without shareholder  approval,  including the right to impose or change fees for
services provided.

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 is 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 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.  The Funds  intend  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.
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.

DESCRIPTIONS OF CERTAIN TYPES OF INVESTMENTS AND INVESTMENT TECHNIQUES AVAILABLE
TO THE FUNDS

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 the 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 a 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. Each 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.  Each 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 the 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 the  Fund,  the  value of a Fund's  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 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,  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.

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.

VARIABLE, FLOATING AND LEVERAGED INVERSE 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.

  The 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.

  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 AMERICA CALIFORNIA INSURED TAX FREE FUND



   
DESCRIPTION OF STATE AND LOCAL TAX TREATMENT
  In the opinion of Messrs.  Orrick,  Herrington  &  Sutcliffe,  California  tax
counsel to the California Insured Fund, dividends paid by the California Insured
Fund that are  derived  from  interest on debt  obligations  that is exempt from
regular federal and California personal income tax will not be subject to either
federal or California personal income tax when received by the California Fund's
shareholders.  The pass through of exempt- interest dividends is allowed only if
the California  Insured Fund meets its federal and California  requirements that
at least 50% of its total assets are invested in such exempt  obligations at the
end of each quarter of its fiscal year. Distributions to individual shareholders
derived from interest on state or municipal  obligations  issued by governmental
authorities in states other than California,  short term capital gains and other
taxable  income will be taxed as dividends for purposes of  California  personal
income taxation.  The Fund's long term capital gains distributed to shareholders
will be taxed as long  term  capital  gains to  individual  shareholders  of the
California  Insured Fund for purposes of California  personal  income  taxation.
Present  California law taxes both long term and short term capital gains at the
rates applicable to ordinary income.  Generally, for corporate taxpayers subject
to the California franchise tax, all distributions will be fully taxable.
    

SPECIAL FACTORS AFFECTING CALIFORNIA
  Through popular initiative and legislative activity,  the ability of the State
and its local  governments to raise money through property taxes and to increase
spending has been the subject of considerable debate and change in recent years.
Various State  Constitutional  amendments,  for example,  have been adopted that
have  the  effect  of  limiting  property  tax  and  spending  increases,  while
legislation  has  sometimes  added to these  limitations  and has at other times
sought to reduce their  impact.  It can be expected  that similar types of State
legislation or Constitutional proposals will continue to be introduced. To date,
these  developments do not appear to have severely  decreased the ability of the
State and local governments to pay principal and interest on their  obligations.
Because of the uncertain impact of the  aforementioned  efforts and legislation,
the  possible  inconsistencies  in the  terms  of  existing  statutes,  and  the
impossibility of predicting the level of future appropriations and applicability
of related statutes to such questions,  it is not currently  possible to predict
the results of such  legislation  and policies on the long term ability of State
and municipal issuers to pay principal and interest on their obligations.

  California's  economy  is large  and  diverse,  accounting  for  about  13% of
national  personal  income.  Growth  was rapid in the 1980s and is  expected  to
continue,  although more moderately.  California's economy is the eighth largest
in the  world  and the  State  ranks  number  one  among  the  fifty  states  in
manufacturing, foreign trade, agriculture, construction and tourism. Through the
1980s,  the rate of state  population  growth  was more than  twice that for the
nation.

  Currently,  California  is  experiencing  the  effects of the  recession  more
severely than the nation.  Personal  income growth has been below national rates
for the past two years and in first  quarter  1993.  Deep  defense  budget cuts,
overbuilt  commercial  real  estate,  consolidation  and  decline in the State's
financial  services  industry  and high  business and living  costs,  especially
compared to neighboring  Western  states,  are expected to produce slower growth
for several years.

  An  expanded   discussion   is  contained  in  the   Statement  of  Additional
Information.

                   KEYSTONE AMERICA MISSOURI TAX FREE FUND


   
DESCRIPTION OF STATE AND LOCAL TAX TREATMENT
  In the opinion of Messrs. Bryan Cave, Missouri tax counsel to the Missouri Tax
Free Fund,  dividends  paid by the  Missouri  Tax Free Fund that  qualify as tax
exempt  dividends  under  Section  852(b)(5)  of the Code  will be  exempt  from
Missouri  income tax to the extent that such dividends are derived from interest
on  obligations  issued  by the  State  of  Missouri  or  any  of its  political
subdivisions,  or interest on  obligations of the U.S. and its  territories  and
possessions  to the extent exempt from  Missouri  income taxes under the laws of
the U.S.

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

  Dividends  and  distributions  derived from the Missouri Tax Free Fund's other
investment  income and its capital  gains,  to the extent  includable in Federal
adjusted  gross income,  will be subject to Missouri  income tax.  Dividends and
distributions paid by the Missouri Tax Free Fund,  including  dividends that are
exempt from  Missouri  income tax as  described  above,  may be subject to state
taxes in states other than  Missouri or to local  taxes.  Shares in the Missouri
Fund are not subject to Missouri personal property taxes.

SPECIAL FACTORS AFFECTING MISSOURI
  Missouri's  economic base is diversified and includes  agriculture,  commerce,
manufacturing,  services,  trade  and  mining.  The  State's  proximity  to  the
geographical and population  centers of the nation makes the State an attractive
location for business and  industry.  The State has  experienced  a  significant
increase in tourism.

  In recent years,  Missouri's  wealth indicators have grown at a rate below the
1980s.  The State's per capita  personal  income has been  growing at a somewhat
slower  rate than the nation as a whole.  Missouri's  unemployment  levels  have
equaled or exceeded the national average in recent years.  Defense contracts are
important to the State's economy and adverse changes in military  appropriations
could contribute to the continuation of this pattern.

  The State  operates  from a General  Revenue  Fund.  The General Fund includes
funds received from tax revenues and federal grants.  The Missouri  Constitution
imposes  a limit on the  amount  of taxes  that may be  imposed  by the  General
Assembly  during any fiscal year. No assurances  can be given that the amount of
revenue  derived from taxes will remain at its current  level or that the amount
of federal grants previously provided to the State will continue.

  An  expanded   discussion   is  contained  in  the   Statement  of  Additional
Information.

<PAGE>
                                                                       EXHIBIT B

                             REDUCED SALES CHARGES


  Initial  sales   charges  may  be  reduced  or   eliminated   for  persons  or
organizations  purchasing  Class A shares of either 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 Internal Revenue 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 under "Rights of Accumulation."  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
Class A 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)")  irrespective  of class.  The Eligible Funds are 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 Class A
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 a 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 so doing, the Purchaser agrees to invest within a thirteen-month
period a specified  amount that,  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 the 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 KDI 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 KDI
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 KDI or KIRC that a Letter of Intent is
in effect each time a purchase is made.

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

   
     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 December 15, 1993. The FUND is one of the twenty-nine  funds managed or
advised by Keystone  Custodian Funds, Inc.  ("Keystone"),  the FUND's investment
adviser.  The FUND  currently  consists of the  following  two  separate  series
evidencing  interests in different  portfolios of securities:  Keystone  America
California  Insured  Tax Free Fund  ("California  Insured  Fund")  and  Keystone
America  Missouri  Tax Free Fund  ("Missouri  Tax Free Fund") (each a "Fund" and
collectively, the "Funds").
    

     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, the 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. -- Municipal  Division
("Fitch"),  as described herein and in the prospectus,  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  generally  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  objectives  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.
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  (as  defined in the
Investment  Company Act of 1940 ("1940 Act")) 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  set forth below are fundamental for each Fund
and may not be changed  without  the vote of a 1940 Act  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 15% of its assets in securities  which may not be sold
or  disposed  of in the  ordinary  course  of  business  within  seven  days  at
approximately the value at which a Fund has valued such securities on its books;

     (3) invest more than 5% of its total assets in securities of any
company  having a record,  together  with its  predecessors,  of less than three
years of continuous operation;

     (4)  pledge  more than 15% of its net  assets to secure  indebtedness;  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 a pledge of assets;

     (5) 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;

     (6) 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;

     (7) 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;

     (8) make short sales of securities or maintain a short position,  unless at
all  times  when a short  position  is open it  owns  an  equal  amount  of such
securities or of securities which, without payment of any further consideration,
are convertible  into or  exchangeable  for securities of the same issue as, and
equal in amount to, the securities sold short;

     (9) 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;

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

     (11) 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;

     (12)  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; or

     (13)  participate on a joint, or a joint and several,  basis in any trading
account in  securities;  the  "bunching"  of orders for the sale or  purchase of
portfolio  securities  with other funds advised by Keystone or its affiliates to
reduce brokerage  commissions or otherwise to achieve best overall  execution is
not considered participation in a trading account in securities.

     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" 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
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,  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 sixth  fundamental
investment restriction above.

     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.

     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,  third, and twelfth  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 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, 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 the 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 that,  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.

REINVESTMENT PRIVILEGE

   
     A shareholder  may elect to make a  reinvestment  purchase with any part of
the proceeds of a total or partial  redemption of Fund shares.  Upon making such
an election,  the FUND will waive the applicable sales charge.  Such an election
must be made within 30 days of the date of such redemption and the purchase must
be of shares of the same Fund.  The number of shares  credited upon  reinvesting
will be  based  on the net  asset  value  of the  Fund's  shares  next  computed
following receipt of the proceeds and request for reinvestment. If a shareholder
exercises this reinvestment  privilege,  any tax loss realized upon the original
sale of Fund shares will not be recognized for federal income tax purposes.  Any
capital  gains,  however,  would be recognized  for federal income tax purposes.
This  reinvestment  privilege  may  be  used  only  once  with  respect  to  any
shareholder.  For tax reporting  purposes,  the FUND will treat a redemption and
subsequent reinvestment purchase as separate transactions.

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

GENERAL

   
     Each Fund offers three classes of shares. Class A shares are offered with a
maximum  sales  charge of 4.75%  payable at the time of  purchase of Fund shares
("Front  End Load  Option").  Class B shares are sold  subject  to a  contingent
deferred  sales charge  payable  upon  redemption  during the  calendar  year of
purchase  and the three  calendar  years  following  calendar  year of purchase.
("Back End Load Option"). Class B shares that have been outstanding during seven
calendar years will automatically convert to Class A shares,  without imposition
of a front end sales charge.  (Conversion of Class B shares represented by stock
certificates  will  require  the return of the stock  certificates  to  Keystone
Investor  Resource  Center,  Inc.  ("KIRC"),  the FUND's  transfer  and dividend
disbursing  agent.)  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 KDI, 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  Plan"), a contingent deferred sales charge may be
imposed at the time of redemption of certain Fund shares as follows:

CLASS A SHARES

     With  certain  exceptions,  purchases  of Class A shares  in the  amount of
$1,000,000  on  which  no  sales  charge  has been  paid  will be  subject  to a
contingent  deferred sales charge of 0.25% upon  redemption  during the one year
period  commencing  on the  date  the  shares  were  originally  purchased.  The
contingent  deferred sales charge will be retained by KDI. See  "Calculation  of
Contingent Deferred Sales Charge" below.

CLASS B SHARES

   
     With certain exceptions, a Fund may 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 the year 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 KDI. 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. If imposed, the deferred sales
charge is deducted from the redemption  proceeds  otherwise  payable to you. The
deferred  sales  charge is  retained  by KDI.  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 cost of such shares.  No contingent
deferred  sales  charge is imposed  when you  redeem  amounts  derived  from (1)
increases in the value of your 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) Class C shares and  certain  Class A shares held during more
than one year;  or (4) Class B shares  held  during  more than four  consecutive
calendar  years.  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

     Shares  also  may 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,  Inc.  ("Keystone  Management"),   Keystone,  Keystone  Group,  Inc.
("Keystone Group"),  Harbor Capital Management  Company,  Inc., any one of their
subsidiaries  or KDI,  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 KDI,  provided 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 Keystone mutual fund 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; or (5) automatic withdrawals under an automatic withdrawal plan of up to
1 1/2% per month of the shareholder's initial account balance.

                               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.  On December 15, 1993,
each  Fund's  Class A, B and C  Distribution  Plans were  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).


     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 NASD 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  Plan,  plus  interest  at the prime  rate plus 1% on such
amounts (less any  contingent  deferred  sales charges paid by  shareholders  to
KDI).


CLASS A DISTRIBUTION PLAN

   
     The Class A Distribution Plan provides that a Fund may expend daily amounts
at an annual rate  currently  limited 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 of a
Fund (currently KDI) 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 maintained
by such recipients outstanding on the books of the FUND for specified periods.
    

     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  maintained  by such
recipients outstanding on the books of the FUND for specified periods.

CLASS B DISTRIBUTION PLAN

   
     The Class B  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 B shares (currently limited to 0.90%) to finance any
activity  that is  primarily  intended  to result in the sale of Class B shares.
Payments  under the Class B  Distribution  Plan are currently made to KDI (which
may  reallow  all or part to others,  such as  dealers)  (1) as  commissions  in
respect of Class B shares sold and (2) as shareholder service fees. Amounts paid
or accrued to KDI under (1) and (2) in the  aggregate  may not exceed the annual
limitation  referred to above.  KDI  generally  reallows to brokers a commission
equal to  3.00% of the  price  paid  for  each  Class B share  sold as well as a
service  fee at the rate of  0.15% of the  average  net  asset  value of Class B
shares  maintained by such  recipients  outstanding on the books of the Fund for
specified periods.
    

     KDI  intends,  but  is  not  obligated,   to  continue  to  pay  or  accrue
distribution  charges incurred in connection with the Class B Distribution  Plan
that exceed  current  annual  payments  permitted to be received by KDI from the
Fund.  KDI 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 the Fund would be
within the permitted limits.

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 (currently limited to 0.90%) to finance any
activity  that is  primarily  intended  to result in the sale of Class C shares.
Payments  under the Class C  Distribution  Plan are currently made to KDI (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
KDI under (1) and (2) in the  aggregate  may not exceed  the  annual  limitation
referred to above. KDI generally  reallows to brokers or others (1) a commission
in the amount of 0.75% of the price paid for each Class C share  sold,  plus the
first  year's  service  fees in advance in the amount of 0.25% of the price paid
for each Class C share sold and (2) beginning approximately fifteen months after
purchase,  a commission at an annual rate of 0.75%  (subject to NASD rules) plus
service fees at an annual rate of 0.25%, respectively,  of the average daily net
asset value of each Class C share  maintained by such recipients  outstanding on
the books of the Fund for specified periods.

DISTRIBUTION PLANS IN GENERAL

   
     Each of the  Distribution  Plans may be terminated as to a Fund at any time
by vote of the Rule 12b-1 Trustees or by a vote of a majority of the appropriate
outstanding voting shares of the Fund.

     Unreimbursed  distribution expenses at November 30, 1994 for Class B shares
were  $784,751  (6.87% of Class B net assets at November  30, 1994) and $862,192
(6.88% of Class B net assets at November  30, 1994) for the  California  Insured
Fund and the Missouri Tax Free Fund, 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 shareholder 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 limits 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.

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

     During the period February 1, 1994 (Commencement of Operations) to November
30, 1994,  the  California  Insured Fund and the Missouri Tax Free Fund paid KDI
(i)  $2,813,  and  $1,634,  respectively,   pursuant  to  each  Fund's  Class  A
Distribution  Plan; (ii) $60,793,  and $61,502,  respectively,  pursuant to each
Fund's Class B Distribution  Plan; and (iii) $3,259,  and $6,508,  respectively,
pursuant to each Fund's Class C Distribution Plan.

     Presently,  a Fund's  class-specific  expenses are limited to  Distribution
Plan  expenses  incurred  by a  class  of  shares  pursuant  to  its  respective
Distribution Plan.

                               INVESTMENT ADVISER

     Subject  to the  general  supervision  of the  FUND's  Board  of  Trustees,
Keystone  serves as investment  adviser to the FUND and is  responsible  for the
overall management of the FUND's business and affairs.

     Keystone, 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  Group,  200  Berkeley  Street,  Boston,  Massachusetts
02116-5034.  Keystone  Group,  a corporation  predominantly  owned by former and
current  members  of  management  of  Keystone  and  its  affiliates,   provides
accounting,  bookkeeping,  legal,  personnel and general  corporate  services to
Keystone,  its affiliates and the Keystone Group of Mutual Funds.  The shares of
Keystone  Group  common stock  beneficially  owned by  management  are held in a
number of voting  trusts,  the  trustees of which are George  Bissel,  Albert H.
Elfner, III, Edward F. Godfrey and Ralph J. Spuehler, Jr.


     Pursuant to its Investment Advisory and Management  Agreement with the FUND
(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  reinvestment  of each Fund's assets in
conformity with such Fund's investment 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 expenses  incurred in  connection  with its
services.  All charges and expenses other than those specifically referred to as
being borne by Keystone will be paid by the FUND, including, but not limited to,
custodian charges and expenses;  bookkeeping and auditors' charges and expenses;
transfer  agent charges and expenses;  fees of Independent  Trustees;  brokerage
commissions,  brokers' fees and expenses;  issue and transfer  taxes;  costs and
expenses  under  the  Distribution  Plans;  taxes  and  trust  fees  payable  to
governmental agencies; the costs of share certificates; fees and expenses of the
registration  and  qualification  of the FUND and its shares with the Securities
and  Exchange  Commission  (sometimes  referred  to  herein  as the "SEC" or the
"Commission") or under state or other  securities  laws;  expenses of preparing,
printing  and  mailing  prospectuses,   statements  of  additional  information,
notices,  reports and proxy materials to  shareholders of the FUND;  expenses of
shareholders' and Trustees' meetings;  charges and expenses of legal counsel for
the FUND and for the  Trustees  of the FUND on  matters  relating  to the  FUND;
charges and expenses of filing  annual and other  reports with the SEC and other
authorities; and all extraordinary charges and expenses of the FUND.

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

Management                                Aggregate Net Asset Value
Fee                                       of the 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.

     During the period February 1, 1994 (commencement of operations) to November
30,  1994,  the  California  Insured Fund and the Missouri Tax Free Fund paid or
accrued to Keystone  investment  management and  administative  services fees of
$49,627 and $47,930, respectively.


     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.



   
     Previously,Keystone  had voluntarily limited the expenses of Class A shares
of each Fund to 0.35% of the average daily net assets of such class until August
15,  1994;  after  which the expense  limitation  was  increased  to 0.45% until
November  15,  1994;  0.55% until  February  15,  1995.  Currently  Keystone has
voluntarily  limited  expenses  of Class A shares to 0.65% of average  daily net
assets until May 15, 1995. Thereafter, Keystone has voluntarily limited expenses
of Class A shares to 0.75% until  December  31, 1995.  Previously,  expenses for
Class B and C shares were  limited to 1.10% of the  average  daily net assets of
such  Class for each Fund until  August  15,  1994;  after  which  such  expense
limitations  were  increased to 1.20% until  November 15, 1994;  and 1.30% until
February 15, 1995.  Currently,  Keystone has voluntarily limited the expenses of
the Class B and C shares to 1.40% of each Class's average daily net assets until
May 15, 1995.  Thereafter,  Keystone has voluntarily limited expenses of Class B
and  Class  C  shares  to  1.50%  until   December  15,  1995.   Thereafter,   a
redetermination of whether to continue these expense  limitations and, if so, at
what  rate,  will  be  made.   Keystone  will  not  be  required  to  make  such
reimbursement  to the extent it would result in a Fund's inability to qualify as
a regulated  investment  company under the provisions of the Code. In accordance
with these expense limitations,  Keystone reimbursed the California Insured Fund
and the  Missouri  Tax Free Fund (i) $23,507  and  $12,109,  respectively,  with
respect to each Fund's Class A shares;  (ii) $81,857 and $91,759,  respectively,
with  respect to each  Fund's  Class B shares;  and (iii)  $4,427  and  $10,208,
respectively, with respect to each Fund's Class C shares.
    

     Each Fund is subject to certain annual state expense limitations,  the most
restrictive of which is as follows:

     2.5% of the first $30 million of Fund average net assets;  2.0% of the next
     $70 million of Fund average net assets; and 1.5% of Fund average net assets
     over $100 million.

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

   
     The  FUND  has  entered  into  a  Principal   Underwriting  Agreement  (the
"Underwriting Agreement"), with KDI, a wholly-owned subsidiary of Keystone. KDI,
as agent,  has agreed to use its best efforts to find purchasers for the shares.
KDI 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 KDI will
bear the expense of preparing,  printing and distributing  advertising and sales
literature  and   prospectuses   used  by  it.  In  its  capacity  as  principal
underwriter,  KDI may receive  payments  from each Fund  pursuant to such Fund's
Distribution Plans.
    

     All  subscriptions  and sales of shares by KDI 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 KDI  assumes the cost of sales
literature  and  preparation  of  prospectuses  used  by it  and  certain  other
expenses.

     From time to time,  if in KDI's  judgment  it could  benefit the sales of a
Fund's  shares,  KDI 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.

     KDI 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,  that  arises out of or is alleged to arise
out of any misrepresentation or omission to state a material fact on the part of
KDI or any other  person for whose acts KDI 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 Trustees of the
FUND and a majority  of the FUND's  Rule 12b-1  Trustees  at least  annually  in
accordance with the 1940 Act and rules and regulations thereunder.

     The Underwriting Agreement may be terminated,  without penalty, on 60 days'
written  notice by a  majority  of the  FUND's  Rule  12b-1  Trustees  or KDI 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 the Advisory
Agreement.  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 that 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.

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


     During the fiscal period ended  November 30, 1994, the FUND did not pay any
brokerage commissions.

                              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  was  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.  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;  and (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 that 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  adversely that 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,  unless  and 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,  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.


     The total returns for the Class A shares of the California Insured Fund and
the  Missouri  Tax Free Fund for the period  February 1, 1994  (commencement  of
operations) to November 30, 1994 were (13.12)% and (12.89)%,  respectively.  The
total  returns  for the Class B shares of the  California  Insured  Fund and the
Missouri  Tax  Free  Fund for the  period  February  1,  1994  (commencement  of
operations) to November 30, 1994 were (11.60)% and (11.66)%,  respectively.  The
total  returns  for the Class C shares of the  California  Insured  Fund and the
Missouri  Tax  Free  Fund for the  period  February  1,  1994  (commencement  of
operations) to November 30, 1994 were (9.95)% and (10.11)%, respectively.

     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.

     The current  yields for the Class A shares of the  California  Insured Fund
and the  Missouri Tax Free Fund for the 30-day  period  ended  November 30, 1994
were 6.19% and 6.12%, respectively. The current yields for the Class B shares of
the California Insured Fund and the Missouri Tax Free Fund for the 30-day period
ended November 30, 1994 were 5.73% and 5.62%,  respectively.  The current yields
for the Class C shares of the California  Insured Fund and the Missouri Tax Free
Fund for the  30-day  period  ended  November  30,  1994 were  5.73% and  5.64%,
respectively.

     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 yields for the Class A shares of the California  Insured
Fund and the  Missouri  Tax Free Fund for an  investor  in the 31%  federal  tax
bracket  for the 30-day  period  ended  November  30, 1994 were 8.97% and 8.87%,
respectively. The tax equivalent yields for the Class B shares of the California
Insured  Fund and the  Missouri Tax Free Fund for an investor in the 31% federal
tax bracket for the 30-day period ended  November 30, 1994 were 8.30% and 8.14%,
respectively. The tax equivalent yields for the Class C shares of the California
Insured  Fund and the  Missouri Tax Free Fund for an investor in the 31% federal
tax bracket for the 30-day period ended  November 30, 1994 were 8.30% and 8.17%,
respectively.

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

               KEYSTONE AMERICA CALIFORNIA INSURED TAX FREE FUND
GENERAL

   
     California's  economy  is the  largest  among the 50 states  and one of the
largest in the world.  The State's  population  of almost 32 million  represents
12.3% of the total U.S. population and grew by 27% in the 1980's. Total personal
income in the State,  at an estimated $683 billion in 1993,  accounts for almost
13% of all personal income in the nation. Total employment is almost 14 million,
the majority of which is in the service, trade and manufacturing sectors.
    

         From  mid-1990 to late 1993,  the State  suffered a recession  with the
worst economic,  fiscal and budget  conditions  since the 1930's.  Construction,
manufacturing (especially aerospace), and financial services, among others, were
all severely affected,  particularly in Southern California. Job losses were the
worst of any post-war  recession.  Employment levels stabilized by late 1993 and
steady growth  occurred in 1994 and is expected in 1995, but  pre-recession  job
levels are not  expected  to be reached for  several  more years.  Unemployment,
while higher than the national average, has come down about 3% in 1994. Economic
indicators  show a steady  recovery  underway in  California  since the start of
1994.

CONSTITUTIONAL LIMITATIONS ON TAXES AND APPROPRIATIONS

   
         LIMITATION ON TAXES.  Certain California  municipal  obligations may be
obligations of issuers that rely in whole or in part, directly or indirectly, on
ad  valorem  property  taxes  as a source  of  revenue.  The  taxing  powers  of
California  local  governments and districts are limited by Article XIIIA of the
California  Constitution,  enacted by the voters in 1978 and  commonly  known as
"Proposition  13."  Briefly,  Article  XIIIA limits to 1% of full cash value the
rate of ad valorem  property taxes on real property and generally  restricts the
reassessment of property to 2% per year,  except upon new construction or change
of ownership (subject to a number of exemptions).  Taxing entities may, however,
raise ad valorem taxes above the 1% limit to pay debt service on  voter-approved
bonded indebtedness.
    

         Under  Article  XIIIA,  the  basic 1% ad  valorem  tax levy is  applied
against the assessed value of property as of the owner's date of acquisition (or
as of March 1, 1975, if acquired earlier), subject to certain adjustments.  This
system has  resulted  in widely  varying  amounts of tax on  similarly  situated
properties.  Several lawsuits have been filed challenging the  acquisition-based
assessment system of Proposition 13, and on June 18, 1992 the U.S. Supreme Court
announced a decision upholding Proposition 13.

   
         Article XIIIA prohibits local governments from raising revenues through
ad valorem  property  taxes above the 1% limit;  it also requires  voters of any
governmental  unit to give two-thirds  approval to levy any "special tax." Court
decisions,  however,  allowed  non-voter  approved levy of "general  taxes" that
were not dedicated to a specific use. In response to these decisions, the voters
of the State in 1986 adopted an initiative statute that imposed  significant new
limits on the ability of local entities to raise or levy general  taxes,  except
by  receiving  majority  local  voter  approval.  Significant  elements  of this
initiative,  "Proposition  62," have been  overturned in recent court cases.  An
initiative   proposed  to  re-enact  the  provisions  of  Proposition  62  as  a
constitutional amendment was defeated by the voters in November 1990, but such a
proposal may be renewed in the future.

         APPROPRIATION  LIMITS.  The State and its local governments are subject
to an annual  "appropriations  limit" imposed by Article XIIIB of the California
Constitution,  enacted  by the  voters  in 1979  and  significantly  amended  by
Propositions 98 and 111 in 1988 and 1990, respectively.  Article XIIIB prohibits
the State or any covered local government from spending  "appropriations subject
to limitation" in excess of the  appropriations  limit imposed.  "Appropriations
subject to limitation"  are  authorizations  to spend "proceeds of taxes," which
consist of tax  revenues  and  certain  other  funds,  including  proceeds  from
regulatory  licenses,  user  charges  or other  fees,  to the  extent  that such
proceeds  exceed the cost of providing the product or service,  but "proceeds of
taxes" excludes most State subventions to local governments. No limit is imposed
on appropriations  of funds that are not "proceeds of taxes," such as reasonable
user charges or fees, and certain other non-tax funds, including bond proceeds.
    

         Among the expenditures not included in the Article XIIIB appropriations
limit  are (1) the debt  service  cost of bonds  issued or  authorized  prior to
January 1, 1979, or subsequently  authorized by the voters,  (2)  appropriations
arising from certain  emergencies  declared by the Governor,  (3) appropriations
for certain capital outlay  projects,  (4)  appropriations  by the State of post
1989 increases in gasoline taxes and vehicle weight fees, and (5) appropriations
made in certain cases of emergency.

         The appropriations  limit for each year is adjusted annually to reflect
changes  in  cost  of  living  and  population  and  any  transfers  of  service
responsibilities   between   governmental   units.   The  definitions  for  such
adjustments  were  liberalized  in 1990 to  follow  more  closely  growth in the
State's economy.

         "Excess" revenues are measured over a two year cycle. Local governments
must return any excess to  taxpayers by rate  reductions.  The State must refund
50% paid to schools and community colleges.  With more liberal annual adjustment
factors since 1988, and depressed  revenues since 1990 because of the recession,
few  governments,  including  the  State,  are  currently  operating  near their
spending limits,  but this condition may change over time. Local governments may
by voter approval exceed their spending limits for up to four years.

   
         Because  of the  complex  nature  of  Articles  XIIIA  and XIIIB of the
California  Constitution,  the ambiguities and possible inconsistencies of their
terms, and the impossibility of predicting  future  appropriations or changes in
population  and  cost  of  living,  and  the  probability  of  continuing  legal
challenges,  it is not  currently  possible  to  determine  fully the  impact of
Article XIIIA or Article XIIIB on California  municipal  obligations.  It is not
presently possible to predict the outcome of any pending litigation with respect
to the ultimate scope,  impact or  constitutionality  of either Article XIIIA or
Article XIIIB, or the impact of any such  determinations  upon State agencies or
local  governments,  or  upon  their  ability  to  pay  debt  service  on  their
obligations. Future initiatives or legislative changes in laws or the California
Constitution  may also affect the ability of the State or local issuers to repay
their obligations.
    

OBLIGATIONS OF THE STATE OF CALIFORNIA

         As of March 1,  1995,  the State had  approximately  $18.9  billion  of
general obligation bonds outstanding,  and $3.7 billion remained  authorized but
unissued.   In  addition,  at  June  30,  1994,  the  State  had  lease-purchase
obligations,  payable  from the State's  General  Fund,  of  approximately  $5.1
billion. In fiscal year 1993-1994,  debt service on general obligation bonds and
lease-purchase  debt was approximately 5.2% of General Fund revenues.  The State
has  paid  the  principal  of and  interest  on its  general  obligation  bonds,
lease-purchase debt and short-term obligations when due.

RECENT FINANCIAL RESULTS

         The principal  sources of General Fund  revenues in 1993-1994  were the
California  personal  income tax (44% of total  revenues),  the sales tax (35%),
bank and corporation  taxes (12%),  and the gross premium tax on insurance (3%).
The State  maintains a Special  Fund for Economic  Uncertainties,"  derived from
General Fund revenues, as a reserve to meet cash needs of the General Fund.

         GENERAL. Throughout the 1980's, State spending increased rapidly as the
State population and economy also grew rapidly, including increased spending for
many  assistance  programs  to local  governments,  which  were  constrained  by
Proposition  13 and other laws. The largest State program is assistance to local
public school  districts.  In 1988, an initiative  (Proposition  98) was enacted
which  (subject to suspension by a two-thirds  vote of the  Legislature  and the
Governor)  guarantees local school districts and community  college  districts a
minimum share of State General Fund revenues (currently 35%).

         Since the start of 1990-91  Fiscal  Year,  the State has faced  adverse
economic,  fiscal,  and budget  conditions.  The  economic  recession  seriously
affected State tax revenues.  It also caused  increased  expenditures for health
and welfare  programs.  The State is also facing a  structural  imbalance in its
budget with the largest  programs  supported  by the  General  Fund  (education,
health,  welfare and corrections)  growing at rates higher than the growth rates
for the principal  revenue  sources of the General Fund. As a result,  the State
entered a period of budget imbalance,  with expenditures  exceeding revenues for
four of the five fiscal years ending in 1991-92;  revenues and expenditures were
about equal in 1992-93. The General Fund had an operating surplus in 1993-94. By
June 30, 1994, the State's General Fund had an accumulated  deficit, on a budget
basis, of approximately $1.8 billion.

   
         CASH FLOW REQUIREMENTS.  Because of the budget deficit accumulated over
the past  several  years,  the  payment of certain  unbudgeted  expenditures  to
schools to maintain constant  per-pupil aid levels, and a reduction of the level
of  available  internal   borrowing,   the  State's  cash  resources  have  been
significantly  depleted.  This has  required  the  State to rely on a series  of
external  borrowings  for the past  several  years to pay its  normal  expenses,
including  repayment of previous cash flow borrowings.  Since June 1992, some of
these  borrowings have gone past the end of the fiscal year. In February,  1994,
the State borrowed $3.2 billion,  maturing by December, 1994. In July, 1994, the
State  borrowed a total of $7.0 billion to meet its cash flow  requirements  for
the 1994-95  fiscal  year,  and to fund a part of its  deficit  into the 1995-96
fiscal year. A total of $4.0 billion of this borrowing  matures in April,  1996.
The State will  continue to have to rely on external  borrowing to meet its cash
needs for the foreseeable future.
    

         RECENT BUDGETS. The State failed to enact its 1992-93 budget by July 1,
1992.  Although  the State had no legal  authority  to pay many of its  vendors,
certain  obligations  (such  as debt  service,  school  apportionments,  welfare
payments,  and employee  salaries) were payable because of continuing or special
appropriations,  or court orders.  However,  the State  Controller  did not have
enough cash to pay, as they came due, all of these ongoing obligations,  as well
as valid obligations incurred in the prior fiscal year.

         Starting  on July  1,  1992,  the  Controller  was  required  to  issue
"registered  warrants"  in lieu of  normal  warrants  backed by cash to pay many
State obligations.  Available cash was used to pay constitutionally mandated and
priority  obligations.  Between  July 1 and  September 3, 1992,  the  Controller
issued an aggregate of approximately $3.8 billion of registered  warrants all of
which were called for redemption by September 4, 1992 following enactment of the
1992-93 Budget Act and issuance by the State of short-term notes.

         The  1992-93  Budget  Act,  when  finally  adopted,  was  projected  to
eliminate the State's accumulated deficit, with additional  expenditure cuts and
a $1.3 billion transfer of State education funding costs to local governments by
shifting  local property taxes to school  districts.  However,  as the recession
continued  longer and deeper than  expected,  revenues once again were far below
projections,  and only reached a level just equal to the amount of expenditures.
Thus,  the State  continued to carry its $2.8 billion budget deficit at June 30,
1993.

         The  1993-94  Budget  Act  represented  a  third  consecutive  year  of
difficult  budget  choices.  As in the prior  year,  the budget  cccontained  no
general  state tax  increases,  and  relied  principally  on  expenditure  cuts,
particularly for health and welfare and higher education,  a two-year suspension
of the renters' tax credit, some one-time and accounting adjustments, and -- the
largest  component -- an additional $2.6 billion transfer of property taxes from
local  government,  particularly  counties,  to school districts to reduce State
education funding requirements.  A temporary state sales tax scheduled to expire
on June 30, 1993 was extended  for six months,  and  dedicated to support  local
government safety costs.

         A major  feature of the budget was a  two-year  plan to  eliminate  the
accumulated  deficit  by  borrowing  into  the  1994-95  fiscal  year.  With the
recession  still  continuing  longer than  expected,  the General  Fund had $800
million less revenue and $800 million higher  expenditures  than budgeted.  As a
result, revenues only exceeded expenditures by about $500 million. However, this
was the first  operating  surplus  in four  years and  reduced  the  accumulated
deficit to $2.0 billion at June 30, 1994 (after taking  account of certain other
accounting reserves).

         CURRENT BUDGET.  The 1994-95 Budget Act was passed on July 8, 1994, and
provides for an estimated  $41.9  billion of General  Fund  revenues,  and $40.9
billion of expenditures. The budget assumed receipt of about $750 million of new
federal assistance for the costs of incarceration, education, health and welfare
related to undocumented immigrants. Other major components of the budget include
further  reductions  in health and welfare  costs and  miscellaneous  government
costs, some additional  transfers of funds from local government,  and a plan to
defer retirement of $1 billion of the accumulated  budget deficit to the 1995-96
fiscal year. The federal government has apparently  budgeted only $33 million of
the expected  immigration aid. However,  this shortfall is expected to be almost
fully  offset by higher  than  projected  revenues,  and  lower  than  projected
caseload growth, as the economy improves.

         As noted above under "Cash Flow  Requirements,"  the State  issued $7.0
billion  of  short-term  debt in July,  1994 to meet its cash flow  needs and to
finance the deferral of part of the  accumulated  budget  deficit to the 1995-96
fiscal year.  In order to assure  repayment of the $4 billion,  22-month part of
this borrowing, the State enacted legislation (the "Trigger Law") which can lead
to automatic,  across-the-board  cuts in General Fund expenditures in either the
1994-95 or 1995-96 fiscal years if cash flow  projections  made at certain times
during those years show  deterioration  from the  projections  made in July 1994
when the borrowings  were made. On November 15, 1994, the State  Controller,  as
part of the Trigger Law,  reported that the cash position of the General Fund on
June 30, 1995 would be about $580 million better than earlier  projected,  so no
automatic budget adjustments were required in 1994-95.  The Controller's  report
showed  that  loss of  federal  funds  was  offset  by  higher  revenues,  lower
expenditures, and certain other increases in cash resources.

         The proposed  Governor's  Budget for the 1995-96  fiscal year  projects
General Fund revenues of $42.5 billion and  expenditures  of $41.7 billion.  The
Governor's  Budget  projects that all the  accumulated  budget  deficits will be
repaid by June 30, 1996,  with a small balance ($92 million) in the Special Fund
for Economic  Uncertainties,  the budget  reserve.  The proposed  budget assumes
receipt of about $830 million of new federal aid for undocumented aliens' costs,
and also  assumes  success in certain  ongoing  litigation  concerning  previous
budget  actions.  The  Governor  has  proposed a 15% cut in personal  income and
corporate taxes, to be phased in over three years starting in 1996.

         The State's  financial  difficulties for the current and upcoming years
will  result  in  continued   pressure   upon  almost  all  local   governments,
particularly  school  districts and counties which depend on State aid.  Despite
efforts in recent years to increase taxes and reduce governmental  expenditures,
there  can be no  assurance  that the  State  will not face  budget  gaps in the
future.

   
         ORANGE  COUNTY.  On December 6, 1994,  Orange County,  California  (the
"County"),  together with its pooled  investment  funds (the "Pools")  filed for
protection  under Chapter 9 of the federal  Bankruptcy  Code, after reports that
the Pools had suffered  significant market losses in their investments causing a
liquidity  crisis  for the Pools  and the  County.  More  than 180 other  public
entities,  most but not all located in the County,  were also  depositors in the
Pools.  As of mid-January,  1995, the County  estimated the Pools' loss at about
$1.7 billion, or 22% of its initial deposits of around $7.5 billion. Many of the
entities that kept moneys in the Pools,  including  the County,  are facing cash
flow difficulties because of the bankruptcy filing and may be required to reduce
programs or capital  projects.  The County and some of these  entities have, and
others may in the future,  default in payment of their obligations.  Moody's and
Standard & Poor's have suspended,  reduced to below investment grade levels,  or
placed on "Credit  Watch"  various  securities  of the  County and the  entities
participating in the Pool.
    

         The State of California has no existing  obligation with respect to any
obligations  or  securities  of the  County  or any of the  other  participating
entities. However, the State may be obligated to intervene to ensure that school
districts   have   sufficient   funds  to  operate,   or  to  maintain   certain
countyadministered state programs.

BOND RATINGS

         State general  obligation bonds are currently rated "A1" by Moody's and
"A" by S&P. Both of these ratings were reduced from "AAA" levels which the State
held  until late  1991.  There can be no  assurance  that such  ratings  will be
maintained  in the  future.  It should  be noted  that the  creditworthiness  of
obligations  issued  by  local  California  issuers  may  be  unrelated  to  the
creditworthiness  of  obligations  issued by the State of  California,  and that
there  is no  obligation  on the  part  of the  State  to make  payment  on such
obligations in the event of default.

LEGAL PROCEEDING.

         The State is involved in certain  legal  proceedings  (described in the
State's recent  financial  statements)  that, if decided against the State,  may
require the State to make significant  future  expenditures or may substantially
impair revenues.

OBLIGATIONS OF OTHER ISSUERS

         OTHER ISSUERS OF CALIFORNIA MUNICIPAL  OBLIGATIONS.  There are a number
of state  agencies,  instrumentalities  and political  subdivisions of the State
that  issue  Municipal  Obligations,  some  of  which  may  be  conduit  revenue
obligations  payable from payments from private  borrowers.  These  entities are
subject to various economic risks and  uncertainties,  and the credit quality of
the securities  issued by them may vary  considerably from the credit quality of
obligations backed by the full faith and credit of the State.

         STATE  ASSISTANCE.  Property tax revenues received by local governments
declined more than 50% following  passage of Proposition 13.  Subsequently,  the
California Legislature enacted measures to provide for the redistribution of the
State's  General Fund surplus to local  agencies,  the  reallocation  of certain
State  revenues to local  agencies and the  assumption  of certain  governmental
functions by the State to assist  municipal  issuers to raise revenues.  Through
1990-91, local assistance (including public schools) accounted for around 75% of
General  Fund  spending.  To  reduce  State  General  Fund  support  for  school
districts,  the 1992-93 and 1993-94  Budget  Acts caused  local  governments  to
transfer a total of $3.9 billion of property  tax revenues to school  districts,
representing  loss of all the  post-Proposition  13  "bailout"  aid. The largest
share of these  transfers  came from  counties,  and the  balance  from  cities,
special districts and redevelopment  agencies.  In order to make up part of this
shortfall, the Legislature proposed, and voters approved, dedicating 0.5% of the
sales tax to counties and cities for public safety  purposes.  In addition,  the
Legislature has changed laws to relieve local  governments of certain  mandates,
allowing them to reduce costs.

         To the extent the State  should be  constrained  by its  Article  XIIIB
appropriations  limit,  or its obligation to conform to Proposition 98, or other
fiscal  considerations,  the  absolute  level,  or the rate of growth,  of State
assistance to local governments may continue to be reduced.  Any such reductions
in State aid could compound the serious fiscal constraints  already  experienced
by many local  governments,  particularly  counties.  At least one rural  county
(Butte) publicly announced that it might enter bankruptcy  proceedings in August
1990,  although such plans were put off after the Governor approved  legislation
to provide  additional funds for the county.  Other counties have also indicated
that their budgetary  condition is extremely  grave. The Richmond Unified School
District  (Contra Cost County) entered  bankruptcy  proceedings in May 1991, but
the proceedings have been dismissed.

   
     ASSESSMENT  BONDS.  California  municipal  obligations  that are assessment
bonds may be adversely  affected by a general decline in real estate values or a
slowdown in real estate sales activity. In many cases, such bonds are secured by
land  that  is  undeveloped  at the  time of  issuance,  but  anticipated  to be
developed  within a few years after issuance.  In the event of such reduction or
slowdown,  such development may not occur or may be delayed,  thereby increasing
the risk of a default on the bonds.  Because  the special  assessments  or taxes
securing  these  bonds  are not the  personal  liability  of the  owners  of the
property assessed,  the lien on the property is the only security for the bonds.
Moreover,  in most  cases the  issuer  of these  bonds is not  required  to make
payments on the bonds in the event of  delinquency in the payment of assessments
or taxes,  except from amounts,  if any, in a reserve fund  established  for the
bonds.
    

         CALIFORNIA  LONG-TERM LEASE OBLIGATIONS.  Certain California  long-term
lease  obligations,  though  typically  payable  from  the  general  fund of the
municipality,  are subject to "abatement" in the event the facility being leased
use and occupancy by the municipality during the term of the lease. Abatement is
not a default,  and there may be no  remedies  available  to the  holders of the
certificates  evidencing the lease obligation in the event abatement occurs. The
most common  cases of  abatement  are failure to  complete  construction  of the
facility  before the end of the period  during  which lease  payments  have been
capitalized  and  uninsured  casualty  losses  to  the  facility  (e.g.  due  to
earthquake).  In the event abatement occurs with respect to a lease  obligation,
lease  payments may be  interrupted  (if all  available  insurance  proceeds and
reserves are exhausted) and the certificates may not be paid when due.

         Several years ago the Richmond Unified School District (the "District")
entered into a lease  transaction  in which certain  existing  properties of the
District  were sold and leased back in order to obtain funds to cover  operating
deficits.  Following a fiscal crisis in which the District's finances were taken
over by a State  receiver  (including  a brief  period  under  bankruptcy  court
protection),  the  District  failed  to make  rental  payments  on  this  lease,
resulting  in a lawsuit by the  Trustee  for the  Certificate  of  Participation
holders,  in which the  State  was a named  defendant  (on the  grounds  that it
controlled the  District's  finances).  One of the defenses  raised in answer to
this lawsuit was the invalidity of the District's  lease. The trial court upheld
the  validity of the lease,  and the case has  subsequently  been  settled.  Any
judgment in a similar case  against the  position  taken by the Trustee may have
adverse  implications  for  lease  transactions  of a  similar  nature  by other
California entities.

OTHER CONSIDERATIONS

         The  repayment of  industrial  development  securities  secured by real
property  may be affected by  California  laws  limiting  foreclosure  rights of
creditors.  Securities  backed  by  health  care and  hospital  revenues  may be
affected by changes in State regulations governing cost reimbursements to health
care providers under Medi-Cal (the State's  Medicaid  program),  including risks
related to the policy of awarding exclusive contracts to certain hospitals.

         Limitations on ad valorem property taxes may  particularly  affect "tax
allocation" bonds issued by California  redevelopment  agencies.  Such bonds are
secured solely by the increase in assessed valuation of a redevelopment  project
area  after the start of  redevelopment  activity.  In the event  that  assessed
values in the  redevelopment  project  decline  (e.g.  because of major  natural
disaster such as an earthquake),  the tax increment  revenue may be insufficient
to make  principal  and interest  payments on these bonds.  Both Moody's and S&P
suspended  ratings on  California  tax  allocation  bonds after the enactment of
Articles XIIIA and XIIIB, and only resumed such ratings on a selective basis.

         Proposition  87, approved by California  voters in 1988,  requires that
all revenues  produced by a tax rate  increase go directly to the taxing  entity
that  increased  such  tax  rate  to  repay  that  entity's  general  obligation
indebtedness.  As a result,  redevelopment  agencies  (which  typically  are the
issuers of tax  allocation  securities)  no longer  receive an  increase  in tax
increment  when taxes on  property in the project  area are  increased  to repay
voter-approved bonded indebtedness.

   
         The effect of these various  constitutional  and statutory changes upon
the ability of  California  municipal  securities  issuers to pay  interest  and
principal on their  obligations  remains  unclear.  Furthermore,  other measures
affecting  the taxing or  spending  authority  of  California  or its  political
subdivisions  may be approved or enacted in the future.  Legislation has been or
may be introduced  that would modify  existing  taxes or other  revenue  raising
measures or that either would further limit or,  alternatively,  would  increase
the  abilities  of state and local  governments  to impose new taxes or increase
existing taxes. It is not presently  possible to predict the extent to which any
such legislation will be enacted.  Nor is it presently possible to determine the
impact of any such legislation on California Municipal  Obligations in which the
Fund may invest,  future  allocations of state revenues to local  governments or
the abilities of state or local governments to pay the interest on, or repay the
principal of, such California municipal obligations.
    

         Substantially  all of  California is within an active  geologic  region
subject to major  seismic  activity.  Northern  California  in 1989 and Southern
California in 1994 experienced major earthquakes  causing billions of dollars in
damages.  The federal government  provided more than $13 billion in aid for both
earthquakes,  and  neither  event is  expected  to have any  long-term  negative
economic impact.  Any security in the California  Insured Fund could be affected
by an interruption of revenues because of damaged facilities,  or, consequently,
income tax deductions for casualty losses or property tax assessment reductions.
Compensatory  financial  assistance could be constrained by the inability of (i)
an issuer to have obtained  earthquake  insurance  coverage at reasonable rates;
(ii) an  insurer  to  perform  on its  contracts  of  insurance  in the event of
widespread  losses;  or (iii) the federal or State  governments  to  appropriate
sufficient funds within their respective budget limitations.


                    KEYSTONE AMERICA MISSOURI TAX FREE FUND

GENERAL

         Missouri's economy includes manufacturing,  commerce,  trade, services,
agriculture,  tourism and mining. The State's economy is diversified and closely
resembles that of the nation's although growth prospects are less favorable than
in the past. It is the nation's  fifteenth  largest state.  The State employment
sectors, services, trade and manufacturing, also account for the primary sources
of national  employment.  Recent growth in the manufacturing sector has outpaced
the nation as a whole.  Labor force growth has remained  steady,  totaling  2.65
million  in 1993,  up from 2.3  million  in 1980.  Through  the 1980's and early
1990's the State's  unemployment  rate essentially  mirrored that of the nation;
however,  adverse  changes in military  appropriations,  which play an important
role in the State's  economy,  could  contribute  to a  significant  increase in
unemployment.  In 1991,  according to the Bureau of Labor Statistics,  the State
ranked fifteenth among the states in unadjusted  nonagricultural  employment and
estimated  the November 1992 adjusted  unemployment  rate to be 4.9%,  below the
national  rate of 7.2%.  In December  1994,  the State's  unemployment  rate was
estimated  to be 4.3% as against the  national  rate of 5.1%.  In recent  years,
Missouri's  wealth  indicators  have grown at a slower rate than national levels
and in 1993 the State's per capita  personal income was  approximately  94.1% of
the average for the nation as a whole.

   
         Missouri displayed strong fiscal performance during most of the 1980's.
However,  Missouri has recently experienced difficulties in balancing its budget
as a result of increased  expenses  and  declining  sources of  revenues.  Other
factors  contributing to Missouri's weak fiscal position relate to the reduction
of large  manufacturing  companies,  including  those in aerospace  and the auto
industry.  The Missouri  portions of the St. Louis and Kansas City  metropolitan
areas together contain over 50% of Missouri's population.  Economic reversals in
either of these two areas  would  have a major  impact on the  overall  economic
condition  of the State of Missouri.  Additionally,  the State of Missouri has a
significant  agricultural sector, which may  experience  problems  comparable to
those which are occurring in other states.  To the extent that any such problems
intensify,  there could  possibly be an adverse  impact on the overall  economic
condition of the State.
    

         Currently,  general  obligations of Missouri are rated "AAA," "Aaa" and
"AAA," by S&P, Moody's and Fitch,  respectively.  There can be no assurance that
the economic  conditions  on which these ratings are based will continue or that
particular  bond issues may not be  adversely  affected by changes in  economic,
political or other conditions.

REVENUES AND LIMITATIONS THEREON

         Approximately 55% of total state revenues are derived from state taxes.
The  major  components  are the  sales and use tax,  individual  income  tax and
corporate  income  tax.  For the  fiscal  year  ended  June  30,  1994,  revenue
collections  were $4,963.6  million,  representing an increase of  approximately
10.1% percent over revenue collections from the previous fiscal year.

         Article  X,  Sections  16-24 of the  Constitution  of  Missouri  (often
referred to as the "Hancock  Amendment")  imposes  limitations  on the amount of
State  taxes that may be  collected  by the State of  Missouri as well as on the
amount of local taxes,  licenses and fees  (including  taxes,  licenses and fees
used to meet debt service  commitments on debt  obligations) that may be imposed
by local governmental units (such as cities,  counties,  school districts,  fire
protection  districts and other similar  bodies) in the State of Missouri in any
fiscal year. The limit is tied to total State revenues for the fiscal year ended
June 30,  1981,  as defined in the  Hancock  Amendment,  adjusted  annually,  in
accordance with the formula set forth in the Amendment,  which adjusts the limit
based on increases  in the average  personal  income of Missouri for  designated
periods.  The details of the  Amendment are too complex and  clarification  from
subsequent legislation and further judicial decisions may be necessary. If total
State  revenues  exceed the State  revenue  limit by more than one percent,  the
State is required to refund the excess.  The revenue  limit can only be exceeded
if the  General  Assembly  approves,  by a  two-thirds  vote of each  House,  an
emergency declared by the Governor.  The revenue limit can also be exceeded by a
constitutional  amendment authorizing new or increased taxes or revenues adopted
by the voters of the State of Missouri.  The revenue limit has not been exceeded
in any past year and current projections  indicate the revenue limit will not be
exceeded in fiscal year 1995.

         The  Hancock   Amendment  further  provides  that  the  State  financed
proportion of the costs of any existing activity or service required of counties
and  other  political  subdivisions  cannot  be  reduced.  In  addition,   State
government  expenses  cannot  exceed the sum of a State's  revenues  (limited as
described above) plus Federal funds and any surplus from a previous year.

         The Missouri  Constitution also limits new taxes, licenses and fees and
increases in taxes,  licenses and fees by local  governmental units in Missouri.
It prohibits  counties and other political  subdivisions  (essentially all local
governmental units) from levying new taxes,  licenses and fees or increasing the
current  levy of an existing  tax,  license or fee  "without the approval of the
required  majority of the  qualified  voters of that  county or other  political
subdivision voting thereon." The Missouri Supreme Court has ruled that the voter
approval requirement on new or increased taxes, licenses and fees does not apply
to traditional user fees such as those charged to customers of municipally owned
utilities.

         If the required  majority of qualified  electors voting on the issuance
of debt  obligations  approves the issuance of the debt obligations and the levy
of taxes or  imposition  of licenses or fees  necessary  to meet the payments of
principal and interest on such debt obligations,  taxes, licenses or fees may be
imposed  or  existing  taxes,  licenses  or fees may be  increased  to cover the
principal and interest on such debt  obligations  without  violating the Hancock
Amendment.  Missouri  constitutional  or  statutory  provisions  other  than the
Hancock  Amendment may require  greater than majority  voter  approval for valid
issuance of certain debt obligations.

         Taxes  may  also  be  increased   by  counties   and  other   political
subdivisions  (but not by the State),  without regard to the  limitations of the
Hancock  Amendment,  for the purpose of paying  principal  and  interest on such
bonds,  other evidences of indebtedness,  and obligations issued in anticipation
of the issuance of bonds, if such bonds and other obligations were authorized to
be issued prior to the adoption of the Hancock Amendment.

         When a local government unit's tax base with respect to certain fees or
taxes is  broadened,  the Hancock  Amendment  requires the tax levy or fee to be
reduced "to yield the same  estimated  gross  revenue as on the prior  base." It
also effectively limits any percentage  increase in property tax revenues to the
percentage  increase  in  the  general  price  level  (plus  the  value  of  new
construction and  improvements),  even if the assessed  valuation of property in
the  local  governmental  unit,  excluding  the  value of new  construction  and
improvements,  increases at a rate  exceeding  the increase in the general price
level.

         To the extent that the payment of general  obligation  bonds  issued by
the State of Missouri or a unit of local  government  in the Missouri  State Tax
Free Fund's  portfolio is dependent on revenues  from the levy of taxes and such
obligations have been issued  subsequent to the date of the Hancock  Amendment's
adoption  (November 4, 1980), the ability of the State or the appropriate  local
unit to levy  sufficient  taxes to pay the debt  service  on such  bonds  may be
affected,  unless there has been specific voter approval of the issuance of such
bonds  and the levy of such  taxes as are  necessary  to pay the  principal  and
interest on such bonds and obligations.

         Debt  obligations  issued by certain state  issuers are payable  either
solely or primarily from the rentals,  incomes and revenues of specific projects
financed with the proceeds of the debt  obligations and are not supported by the
taxing powers of the State or of the issuer of the bonds. The Hancock  Amendment
may most strongly  affect such State revenue bonds,  since they are dependent in
whole or in part on appropriations of the General Assembly to provide sufficient
revenues to pay principal  and  interest.  Unless such bonds are approved by the
voters of Missouri, under the Hancock Amendment, taxes cannot be raised to cover
the State  appropriations  necessary to provide  revenues to pay  principal  and
interest on the bonds.  Consequently,  payment of principal and interest on such
state revenue bonds or other obligations,  relating to specific projects and not
supported by the taxing  power of the State of Missouri,  may not be made or may
not be made in a timely  fashion  because of (i) the  inability  of the  General
Assembly  to  appropriate   sufficient  funds  for  the  payment  of  such  debt
obligations  (or to make up shortfalls  therein) due to the limitations on State
taxes and expenditures  imposed by the Hancock Amendment;  (ii) the inability of
the issuer to  generate  sufficient  income or revenue  from the project to make
such payment; or (iii) a combination of the above.

         As described  above,  general  obligations  bonds and revenue  bonds of
local governmental units, including counties, cities and similar municipalities,
sewer  districts,  school  districts  and  other  similar  issuers,  may also be
affected by the tax,  license  and fee  limitations  of the  Hancock  Amendment.
Unless the required voter approval of such debt  obligations  and the imposition
of taxes to pay them is obtained prior to their issuance,  the Hancock Amendment
imposes  limitations on the imposition of new taxes and the increase of existing
taxes which may be necessary to pay principal and interest on general obligation
bonds of local issuers.  The limitations  contained in the Hancock Amendment may
also affect the payment of principal and interest on bonds and other obligations
issued by local  governmental units and supported by the revenues generated from
user fees,  licenses  or other fees and  charges,  unless  the  requisite  voter
approval of the issuance of such bonds or other obligations, and the approval of
the  assessment  of such fees or other  charges as may be  necessary  to pay the
principal  and interest on such bonds or other  obligations,  has been  obtained
prior to their issuance.

         Debt  obligations  of  certain  other  state  and  local  agencies  and
authorities  are not,  by the terms of their  respective  authorizing  statutes,
obligations of the State or any political subdivision, public instrumentality or
authority,  county,  municipality  or other  state or local unit of  government.
Illustrative of such issuers are the Missouri  Housing  Development  Commission,
the State Environmental  Improvement and Energy Resources Authority,  the Health
and  Educational  Facilities  Authority of the State of  Missouri,  the Missouri
Higher Education Loan Authority,  the Industrial  Development Board of the State
of Missouri,  the Missouri Agricultural and Small Business Development Authority
and  other  similar  bodies  organized  on a local  level  under  similar  state
authorizing   statutes  such  as  the  various  local   industrial   development
authorities,  planned  industrial  expansion  authorities and land clearance for
redevelopment authorities. The debt obligations of such issuers are payable only
from the revenues generated by the project or program financed from the proceeds
of  the  debt  obligations  they  issue,  and  the  Hancock   Amendment  has  no
application.

INDUSTRY AND EMPLOYMENT

         While Missouri has a diverse  economy with a  distribution  of earnings
and  employment   among   manufacturing,   trade  and  service  sectors  closely
approximating the average national distribution, the national economic recession
of the early 1980's had a  disproportionately  adverse  impact on the economy of
Missouri.  During  the  1970's,  Missouri  characteristically  had a pattern  of
unemployment levels well below the national averages. However, since the 1980 to
1983 recession periods Missouri  unemployment  levels generally  approximated or
slightly  exceeded  the  national  average.  A  return  to  a  pattern  of  high
unemployment  could adversely affect the Missouri debt  obligations  acquired by
the Missouri Fund and, consequently, the value of the shares of the Fund.

         The  Missouri  portions of the St.  Louis and Kansas City  metropolitan
areas  contain  approximately  1,939,500  and 975,241  residents,  respectively,
constituting  over  fifty  percent  of  Missouri's  1994  population  census  of
approximately  5,278,000.  St.  Louis  is an  important  site  for  banking  and
manufacturing  activity,  as well as a distribution and  transportation  center,
with eight Fortune 500 industrial companies (as well as other major educational,
financial,   insurance,  retail,  wholesale  and  transportation  companies  and
institutions)  headquartered  there.  Kansas City is a major agribusiness center
and an important center for finance and industry.  Economic  reversals in either
of these two areas would have a major impact on the overall  economic  condition
of the State of Missouri.  Additionally, the State of Missouri has a significant
agricultural  sector which is experiencing  farm-related  problems comparable to
those which are  occurring in other  states.  To the extent that these  problems
were to  intensify,  there could  possibly  be an adverse  impact on the overall
economic condition of the State of Missouri.

         Defense related business plays an important role in Missouri's economy.
In addition to the large  number of civilians  employed at the various  military
installations and training bases in the State,  aircraft and related  businesses
in Missouri are the recipients of  substantial  annual dollar volumes of defense
contract awards.  McDonnell Douglas Corporation is the State's largest employer,
currently  employing  approximately  24,000 employees in Missouri.  In the past,
Missouri  has ranked in the top six states in total  military  contract  awards,
however due to recent  large cuts in the  defense  budget,  Missouri  dropped to
tenth in 1992 in the dollar  volume of defense  contracts.  This compares to its
population  ranking as the nation's  fifteenth largest state.  Recent changes in
the levels of military  appropriations  and the cancellation of the A-12 program
has affected  McDonnell Douglas  Corporation in Missouri and over the last three
years it has reduced its Missouri work force by approximately  30%. There can be
no  assurances  that  there will be  further  changes in the levels of  military
appropriations,   and,   to  the  extent  that   further   changes  in  military
appropriations  are enacted by the United  States  Congress,  Missouri  could be
disproportionately affected.

OTHER FACTORS

         Desegregation lawsuits in St. Louis and Kansas City, and a U.S. Supreme
Court decision continue to require  significant  levels of state funding and are
sources of uncertainty.  Litigation  continues on many issues,  court orders are
unpredictable,  and school district  spending  patterns have proven difficult to
predict.  The State paid $277.5 million for  desegregation  costs in fiscal 1994
and the budget for fiscal 1995 provides  $358.9 million.  This expense  accounts
for close to 7% of total state General Revenue Fund spending.

                      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 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.

D.   MOODY'S CORPORATE AND MUNICIPAL BOND RATINGS

         Moody's ratings are as follows:

         1. Aaa - Bonds that 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 that 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  that  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  that  suggest a  susceptibility  to  impairment  sometime in the
future.

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

         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 that 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 that 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 "World Bank", 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  ("CPOs") 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 that  distinguishes CPOs from municipal debt is that the lease
that 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 that 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, 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 CON-
TRACTS 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.

         Each Fund  intends  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 America State Tax Free Fund-Series II 

NOTES TO FINANCIAL STATEMENTS 

(1.) Significant Accounting Policies 

Keystone America State Tax Free Fund-Series II ("FUND") was formed as a 
Massachusetts business trust on December 15, 1993 and is registered under the 
Investment Company Act of 1940 (the Act) as an open-end management investment 
company. Keystone Custodian Funds, Inc. ("Keystone") is the Investment 
Adviser. The FUND currently offers shares of two separate series evidencing 
interests in different portfolios of securities ("Fund(s)"), the Keystone 
America California Insured Tax Free Fund ("California Fund") and the Keystone 
America Missouri Tax Free Fund ("Missouri Fund") which had no operations 
prior to February 1, 1994. The Funds are registered under the Act as 
non-diversified open-end investment companies. 

Each Fund currently issues three classes of shares. Class A shares are 
charged a 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 Distributors, Inc. ("KDI"), the FUND's principal underwriter. 

Keystone is a wholly-owned subsidiary of Keystone Group, Inc. ("KGI"), a 
Delaware corporation. KGI is privately owned by an investor group consisting 
of members of current and former 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 Funds in the preparation of their financial statements. The 
policies are in conformity with generally accepted accounting principles. 

A.  Tax-exempt bonds are valued 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 
purchase 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 amortization 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. 

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, each 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 a 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 a 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 federal taxable income.
<PAGE>
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 the 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 on the trade date. Interest 
income is recorded on the accrual basis. All premiums and original issue 
discounts are amortized/accreted for both financial reporting and federal 
income tax purposes. Realized gains and losses are recorded on the identified 
cost 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 is 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. When a Fund enters into a repurchase agreement (a purchase of securities 
whereby the seller agrees to repurchase the securities at a mutually agreed 
upon date and price) the repurchase price of the securities will generally 
equal the amount paid by the Fund plus a negotiated interest amount. The 
seller under the repurchase agreement will be required to provide securities 
("collateral") to the Fund whose value will be maintained at an amount not 
less than the repurchase price and which generally will be maintained at 101% 
of the repurchase price. A Fund monitors the value of the collateral on a 
daily basis, and if the value of the collateral falls below required levels, 
the Fund intends to seek additional collateral from the seller or terminate 
the repurchase agreement. If the seller defaults, a Fund would suffer a loss 
to the extent that the proceeds from the sale of the underlying securities 
were less than the repurchase price. Any such loss would be increased by any 
cost incurred on disposing of such securities. If bankruptcy proceedings are 
commenced against the seller under the repurchase agreement, the realization 
on the collateral may be delayed or limited. Repurchase agreements entered 
into by a Fund will be limited to transactions with dealers or domestic banks 
believed to present minimal credit risks, and the Fund will take constructive 
receipt of all securities underlying repurchase agreements until such 
agreements expire. 

F. 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.

<PAGE>
G. Distributions from net investment income are based on tax basis net 
income. From time to time, the Fund may distribute dividends which exceed 
book basis net income. Differences between book basis investment income--net 
available for distribution and tax basis investment income--net available for 
distribution are primarily attributable to differences in the treatment of 
12b-1 Distribution Plan charges and tax basis returns of capital. 

(2.) Capital Share Transactions 

The Declaration of Trust 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 cost of selling its shares under a Distribution 
Plan adopted with respect to its Class A, Class B and Class C shares. 

The 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 KDI under the 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 daily net asset value of shares sold by such others and remaining 
outstanding on the books of the Fund for specified periods. 

The Class B Distribution Plan provides for payments at an annual rate of up 
to 1.00% (currently limited to 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 share sold by 
such others and remaining outstanding on the books of the Fund for specified 
periods. 

The Class C Distribution Plan provides for payments at an annual rate of up 
to 1.00% (currently limited 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 payment at the time of purchase of 1.00% of the 
value of each share sold, such payment to consist of a commission in the 
amount of 0.75% and the first year's service fee in advance in the amount of 
up to 0.25% (currently limited to 0.15%); (ii) beginning approximately 15 
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 
Security Dealers, Inc.) and service fees at an annual rate of up to 0.25% of 
the average net asset value of shares sold by such others and remaining 
outstanding on the books of the Fund for specified periods. 

Each of the Distribution Plans may be terminated at any time by vote of the 
Independent Trustees or by majority of the outstanding voting shares of the 
respective class. However, after the termination of the Class B Distribution 
Plan, payments to KDI will continue at the annual rate of 1.00% of the 
average daily

(4.) Investment Management and Transactions with Affiliates 

Under the terms of the Investment Advisory and Management Agreement between 
Keystone and the FUND, dated December 15, 1993, Keystone provided investment 
advisory and management services to the FUND and its Funds. 

In return, Keystone was paid an amount computed and paid daily by applying 
percentage rates, which start at 0.55% and decline, as net assets increase, 
to 0.25%, to the average annual net asset value of each Fund. 

During the period February 1, 1994 (Commencement of Operations) to November 
30, 1994, the California Fund and the Missouri Fund paid or accrued to 
Keystone investment management and administrative services fees of $49,627, 
and $47,930, respectively. 

During the period February 1, 1994 (Commencement of Operations) to November 
30, 1994, the California Fund and the Missouri Fund paid or accrued to KIRC

period February 1, 1994 (Commencement of Operations) to November 30, 1994, 
the California Fund and the Missouri Fund paid or accrued to KGI $11,753, and

Keystone had voluntarily limited the expenses of Class A Shares of each Fund 
to 0.35% for six months, after which the expense limitation was increased by 
0.10% per month until November 1, 1994 when expenses were limited to 0.75%; 
expenses for Class B and C shares were limited to 1.10% for the Fund's first 
six months, after which the expense limitations were similarly increased 
until November 1, 1994 when expenses were limited to 1.50%. These expense 
limitations will continue until December 31, 1995. Keystone will not be 
required to make such reimbursement to the extent it 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 these expense limitations, 
Keystone reimbursed the California Fund and the Missouri Fund (i) $23,507 and 
$12,109, respectively, with respect to each Fund's Class A Shares; (ii) 
$81,857 and $91,759, respectively, with respect to each Fund's Class B 
Shares; and (iii) $4,427 and $10,208, respectively, with respect to each 
Fund's Class C Shares. Keystone does not intend to seek repayment for these 
amount. 

 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.
