  Keystone  Intermediate Term Bond Fund (formerly Keystone America  Intermediate

classes and their fee and sales charge structures may be found in the Fund's fee
table,  "Alternative  Sales  Options,"  "Contingent  Deferred  Sales Charges and
Waiver of Sales Charges," "Distribution Plans," and "Fund Shares."

<FN>
<F1>Class B shares  purchased on or after June 1, 1995 convert tax free to Class A shares after eight years.  See "Class B Shares"
    for more information.
<F2>Class c shares are  available  only  through  dealers who have  entered into special  distribution  agreements  with  Keystone
    Investment Distributors Company, the Fund's principal underwriter.
<F3>The sales charge applied to purchases of Class A shares  declines as the amount invested  increases.  See  "Alternative  Sales
    Options."
<F4>Purchases of Class A shares in the amount of  $1,000,000 or more and/or  purchases  made by certain  qualifying  retirement or
    other plans are not subject to a sales  charge at the time of  purchase,  but may be subject to a  contingent  deferred  sales
    charge.  See the "Class A Shares" and the  "Contingent  Deferred  Sales Charge and Waiver of Sales  Charges"  sections of this
    prospectus for an explanation of the charge.
<F5>There is no fee for exchange orders received by the Fund directly from a shareholder  over the Keystone  Automated  Response
    Line ("KARL"). (For a description of KARL, see "Shareholder Services")
<F6>Expense  ratios are for the fiscal year ended July 31, 1994 after giving effect to Keystone's  reimbursement  of Fund expenses
    in accordance with certain voluntary expense limits. Prior to reimbursement, expense ratios for the fiscal year ended July 31,
    1994 for the Fund's Class A, B, and C shares,  respectively,  were 1.80%,  2.36%,  and 2.37%.  For an  explanation  of expense
    reimbursements,  see "Fund  Management  and  Expenses."  Until July 31, 1995,  the Fund's  investment  adviser  currently  has
    voluntarily limited expenses of Class A shares to 1.00% of their average daily net assets and expenses of Class B and C shares
    to 1.75% of each such class's average daily net assets.
<F7>Long term  shareholders  may pay more than the  equivalent of the maximum  front end sales  charges  permitted by the National
    Association of Securities Dealers, Inc. ("NASD").
<F8>The Securities and Exchange Commission  requires use of a 5% annual return figure for purposes of this example.  Actual return
    for the Fund may be greater or less than 5%.

<F2>Effective August 1, 1993, the Fund adopted Statement of Position 93-2:  "Determination,  Disclosure,  and Financial  Statement
    Presentation of Income, Capital Gain and Return of Capital Distributions by Investment  Companies." As a result,  distribution
    amounts  exceeding  book basis net income (or tax basis net income on a temporary  basis) are presented as  "Distributions  in
    excess of net investment  income."  Similarly,  capital gain distributions in excess of book basis capital gains (or tax basis

THE FUND
  The Fund is an open-end,  diversified,  management  investment company (mutual
fund).  The Fund was formed as a  Massachusetts  business  trust on October  24,
1986.  The Fund is one of twenty  funds  managed by  Keystone  Management,  Inc.
("Keystone  Management"),  the Fund's investment  manager,  and is one of thirty
funds advised by Keystone Investment Management Company (formerly named Keystone
Custodian Funds, Inc.) ("Keystone"), the Fund's investment adviser. Keystone and
Keystone  Management  are, from time to time, also  collectively  referred to as
"Keystone."

INVESTMENT OBJECTIVES AND POLICIES
  The Fund seeks  current  income by  investing  primarily  in a broad  range of
investment quality debt securities.  As a secondary objective, the Fund seeks to
protect capital. Where appropriate the Fund will take advantage of opportunities
to realize capital appreciation.

PRINCIPAL INVESTMENTS
  The Fund seeks current income by normally investing at least 80% of its assets
in debt securities  including United States ("U.S.")  Treasury bills,  notes and
bonds,  mortgage-backed  securities issued by the U.S.  government or one of its
agencies  or  instrumentalities,  mortgage-backed  securities  issued by private
issuers, corporate debt securities and commercial paper.

  Under ordinary  circumstances,  the Fund expects to invest at least 65% of its
assets in bonds and  debentures.  In  addition,  the Fund will only  invest  its
assets in securities  which at the time of investment  are rated 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) and 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.  Any  split-rated  bond in which
the Fund invests  will be rated at least the minimum  rating by both Moody's and
S&P. The Fund's  investments  are expected to have a minimum average rating of A
by Moody's, S&P or Fitch.

  It is currently expected that under normal circumstances,  the dollar weighted
average  maturity  of the  Fund's  investments  will  range  from 3 to 7  years.
However,  the Fund may invest in  securities  with  remaining  maturities of ten
years or less.

  The Fund's debt  securities may include fixed and adjustable  rate or stripped
bonds,  debentures,   notes,  equipment  trust  certificates,   debt  securities
convertible into, or exchangeable  for,  preferred or common stock. The Fund may
also invest in units,  which are debt  securities  with stock or warrants to buy
stock  attached,  and  preferred  stock.  The Fund will not invest in securities
judged to be speculative  or of poor quality but may invest in investment  grade
securities described above.

  Bonds  which  are  rated  BBB  or  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.  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.  Such bonds lack outstanding investment characteristics and may have
speculative  characteristics.  Keystone will dispose of any bond whose rating is
reduced below BAA by Moody's, BBB by S&P or BBB by Fitch.

  When the Fund buys  securities,  it will consider the ratings of Moody's,  S&P
and  Fitch  assigned  to  various  debt  securities.  In making  its  investment
decisions the Fund will also  consider  many factors  other than current  yield,
including the  preservation  of capital,  the  potential  for realizing  capital
appreciation,  maturity  and  yield  to  maturity.  The  Fund  will  adjust  its
investments in particular  securities or in types of debt securities in response
to its appraisal of changing economic  conditions and trends.  The Fund may sell
one security and purchase another security of comparable quality and maturity to
take  advantage  of what it believes to be  short-term  differentials  in market
values or yield disparities.

OTHER ELIGIBLE SECURITIES
  The Fund may invest up to 20% of its total assets under ordinary circumstances
and, when in Keystone's  opinion market  conditions  warrant,  up to 100% of its
assets for temporary defensive purposes,  in the following types of money market
instruments:  (1) commercial paper,  including master demand notes, which 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 which
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  having  at least $1
billion  in assets as of the date of their  most  recently  published  financial
statements and which 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  which at the date of investment are rated A or better by
S&P or Moody's;  and (4) obligations issued or guaranteed by the U.S. government
or by any agency or instrumentality of the U.S.

  The Fund may enter into repurchase and reverse repurchase agreements, purchase
and sell  securities and currencies on a when issued and delayed  delivery basis
and purchase or sell  securities on a forward  commitment  basis,  write covered
call and put options  and  purchase  call and put options to close out  existing
positions and may employ new investment techniques with respect to such options.
The Fund may also enter into currency and other 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,  the Fund may invest in foreign  securities  and
securities denominated in foreign currencies.

  In addition,  the Fund may also invest in inverse floating rate collateralized
mortgage obligations ("CMOs") and interest only ("IO") and principal only ("PO")
stripped mortgage obligations,  all of whose underlying securities are issued by
or  guaranteed  as to principal and interest by the full faith and credit of the
U.S. government.

  The Fund may also  invest in certain  other types of  derivative  instruments,
including  interest rate swaps,  equity swaps,  index swaps,  currency swaps and
caps and floors,  in addition to  forwards,  futures,  options,  mortgage-backed
securities and other  asset-backed  securities as mentioned  above.  These basic
vehicles  can also be combined to create more  complex  products  called  hybrid
derivatives or structured securities.

  For  further  information  about  the  types  of  investments  and  investment
techniques  available  to the Fund,  including  the  associated  risks,  see the
section of this prospectus entitled "Additional Investment  Information" and the
statement of additional information.

  Of course, there can be no assurance that the Fund will achieve its investment
objectives since there is uncertainty in every investment.

FUNDAMENTAL NATURE OF INVESTMENT OBJECTIVES
  The investment  objectives of the Fund 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 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
  The Fund has adopted the fundamental  restrictions summarized below, which may
not be changed without the vote of a 1940 Act majority of the Fund's outstanding
shares.  These  restrictions  and certain other  fundamental and  nonfundamental
restrictions  are set forth in the statement of additional  information.  Unless
otherwise  stated,  all  references to the Fund's assets are in terms of current
market value.

  Generally,  the Fund may not do the following:  (1) with respect to 75% of its
total assets,  invest more than 5% of its total assets in the  securities of any
one issuer (other than U.S.  government  securities);  (2) borrow money,  except
that the Fund may 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 and may
enter into reverse  repurchase  agreements,  and (3) invest more than 25% of its
total assets in securities of issuers in the same industry.

  The Fund intends to follow policies of the Securities and Exchange  Commission
as they are  adopted  from time to time with  respect  to  illiquid  securities,
including,  at this time, (1) treating as illiquid,  securities which may not be
sold or disposed of in the  ordinary  course of  business  within  seven days at
approximately the value at which the Fund has valued the investment on its books
and (2) limiting its holdings of such securities to 15% of net assets.

  As a matter of  practice  the 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  second  investment
restriction above.

  Although not fundamental  restrictions  or policies  requiring a shareholders'
vote to change, 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  (1) may not  write  or  sell  puts,  calls  or
combinations thereof, except that it may write covered put and call options, (2)
in  connection  with the purchase of debt  securities,  may acquire  warrants or
other rights to subscribe for  securities of issuers or securities of parents or
subsidiaries  of such issuers  (warrants),  provided that no more than 5% of its
total assets may be invested in warrants  (for the purpose of this  restriction,
warrants attached to securities acquired by the Fund may be deemed to be without
value),  and (3) may not  invest  in  interests  in oil,  gas or  other  mineral
exploration  or  development  programs,  except  publicly  traded  securities of
companies  engaging in such activities;  in any case,  unless  authorized by the
vote of a majority of the Fund's outstanding voting shares.

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

  By itself,  the Fund does not constitute a balanced  investment plan. The Fund
stresses  earning  income by  investing in fixed  income  securities,  which are
generally considered to be interest rate sensitive.  This means that their value
(and the Fund's share prices) will tend to decrease when interest rates rise and
increase  when  interest  rates fall.  Shorter term bonds are less  sensitive to
interest rate changes, but longer term bonds generally offer higher yields.

  When choosing  among bond funds,  you should  consider the  anticipated  yield
together with potential  changes in share price, as these two factors  determine
each fund's total return to investors.  The yield and potential price changes of
each  fund  depend  on  the  quality  and  maturity  of the  obligations  in its
portfolio,  as well as on market conditions.  The Fund is for investors who seek
income, but want a portfolio of primarily  investment grade bonds. To the extent
that  investments  are  made in debt  securities  (other  than  U.S.  government
securities),  derivatives or structured  securities,  such investments,  despite
favorable credit ratings, are subject to some risk of default.

  Investment  yields  on  relatively  short-term   investments  are  subject  to
substantial and rapid fluctuation. Specifically, the market value of traditional
fixed  income debt  securities  generally  will vary  inversely  with changes in
interest rates. For example, in the case of an investment in a traditional fixed
income  debt  security,  if  interest  rates  increase  after  the  security  is
purchased,  the  security,  if sold prior to maturity,  may return less than its
cost.  The  market  value  of  derivatives  or  structured  securities  may vary
depending upon the manner in which the investments  have been structured and may
fluctuate much more rapidly and to a much greater extent.  As a result the value
of  such  investments  may  change  at a rate in  excess  of the  rate at  which
traditional fixed income  securities  change and,  depending on the structure of
the  derivative,  would change in a manner  opposite to the change in the market
value  of a  traditional  fixed  income  security.  See  "Additional  Investment
Information"  for  further  discussion  of the  risks  inherent  in  the  use of
derivatives.

  Investing in securities of foreign  issuers  generally  involves  greater risk
than investing in securities of domestic issuers for the following reasons:

    (1) there may be less public  information  available about foreign companies
  than is available about U.S. companies;

    (2) foreign companies are not generally  subject to the uniform  accounting,
  auditing and financial  reporting  standards and practices  applicable to U.S.
  companies;

    (3) foreign  stock  markets have less volume than the U.S.  market,  and the
  securities  of some foreign  companies  are less liquid and more volatile than
  the securities of comparable U.S. companies;

    (4)  foreign   securities   transactions   may  involve   higher   brokerage
  commissions;

    (5) there may be less  government  regulation of stock  exchanges,  brokers,
  listed companies and banks in foreign countries than in the U.S.;

    (6)  the  Fund  may  incur  fees  on  currency  exchanges  when  it  changes
  investments from one country to another;

    (7) the Fund's  foreign  investments  could be  affected  by  expropriation,
  confiscatory  taxation,  nationalization,  establishment of exchange controls,
  political or social instability or diplomatic developments;

    (8) foreign governments may withhold income on investments; and

    (9)  fluctuations  in foreign  exchange  rates will  affect the value of the
  Fund's  investments,  the value of dividends  and interest  earned,  gains and
  losses  realized  on  the  sale  of  securities,  net  investment  income  and
  unrealized appreciation or depreciation of investments.

  Current yield levels should not be considered representative of yields for any
future period of time. Moreover,  should many shareholders change from this Fund
to some other  investment  at about the same  time,  the Fund might have to sell
portfolio  securities at a time when it would be disadvantageous to do so and at
a lower price than if such securities were held to maturity.

  If and when the 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 the interest on
these  securities  is  reported  as  income to the 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.

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 the  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 the 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.

  The Fund values publicly traded bonds 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. The Fund values short-term  instruments having
maturities  of more than  sixty days for which  market  quotations  are  readily
available at current  market  value;  the Fund values  money market  instruments
which are  purchased  with  maturities  of sixty days or less at amortized  cost
(original  purchase cost as adjusted for amortization of premium or accretion of
discount),  which, when combined with accrued interest  approximates market; and
money market  instruments  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;  and in any 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 Fund's Board of Trustees.

DIVIDENDS AND TAXES
  The Fund has  qualified  and  intends to qualify in the future as a  regulated
investment  company  under the  Internal  Revenue  Code (the  "Code").  The Fund
qualifies if, among other things,  it distributes to its  shareholders  at least
90% of its net  investment  income for its fiscal year. The 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  dividend  declared in October,  November or December to shareholders of
record in such month, and paid by the following January 31 will be includable in
the taxable income of the  shareholders as if paid on December 31 of the year in
which the dividend was declared. If the Fund qualifies and if it distributes all
of its net investment income and net capital gains, if any, to shareholders,  it
will be relieved of any federal income tax liability.

  The Fund  will  make  distributions  from its net  investment  income  and net
capital  gains,   if  any,  at  least   annually.   Shareholders   receive  Fund
distributions  in the form of  additional  shares of that  class of shares  upon
which the distribution is based or, at the  shareholder's  option, in cash. Fund
distributions  in the form of  additional  shares  are made at net  asset  value
without the imposition of a sales charge.

  Because Class A shares bear most of the costs of  distribution  of such shares
through  payment of a front end sales  charge,  while Class B and Class C shares
bear  such  expenses  through  a  higher  annual   distribution   fee,  expenses
attributable to Class B shares and Class C shares will generally be higher,  and
income  distributions  paid by the Fund  with  respect  to  Class A shares  will
generally be greater than those paid with respect to Class B and Class C shares.

  Dividends and  distributions  are taxable whether they are received in cash or
in shares.  Income  dividends and net short-term  gains dividends are taxable as
ordinary  income,  and net  long-term  dividends  are  taxable as capital  gains
regardless  of how long the Fund's shares are held. If Fund shares held for less
than six months are sold at a loss,  however,  such loss will be treated for tax
purposes  as a long-term  capital  loss to the extent of any  long-term  capital
gains dividends received.  The Fund advises its shareholders  annually as to the
federal tax status of all distributions made during the year.

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.
Subject to the authority of the Fund's Board of Trustees,  Keystone  Management,
located at 200  Berkeley  Street,  Boston  Massachusetts  02116-5034,  serves as
investment  manager to the Fund and is responsible for the overall management of
the Fund's business and affairs.

INVESTMENT MANAGER
  Keystone  Management,  the Fund's investment manager,  organized in 1989, is a
wholly-owned  subsidiary of Keystone,  and its directors and principal executive
officers have been affiliated with Keystone,  a seasoned investment adviser, for
a number of years. Keystone Management also serves as investment manager to most
of the other  Keystone  America Funds and to certain other funds in the Keystone
Investments Family of Funds.

  Pursuant to its Investment  Management  Agreement  with the Fund  ("Management
Agreement"),   Keystone  Management  has  delegated  its  investment  management
functions, except for certain administrative and management services to Keystone
and has entered into an Investment  Advisory Agreement with Keystone  ("Advisory
Agreement") under which Keystone will provide investment advisory and management
services to the Fund.  Services  performed  by Keystone  Management  include (1)
performing research and planning with respect to (a) the Fund's qualification as
a regulated investment company under Subchapter M of the Code, (b) tax treatment
of the Fund's  portfolio  investments,  (c) tax  treatment of special  corporate
actions (such as reorganizations), (d) state tax matters affecting the Fund, and
(e) the Fund's  distributions  of income and capital  gains;  (2)  preparing the
Fund's  federal  and state tax  returns;  (3)  providing  services to the Fund's
shareholders in connection with federal and state taxation and  distributions of
income and  capital  gains;  and (4)  storing  documents  relating to the Fund's
activities.

  The Fund pays  Keystone  Management  a fee for its services at the annual rate
of:

                                                                     Aggregate

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 year  ended July 31,  1994,  the Fund paid or accrued to  Keystone
Management investment  management and administrative  services fees of $290,111,
which represented 0.60% of the Fund's average net assets on an annualized basis.
Of such amount paid to Keystone  Management,  $246,594  was paid to Keystone for
its services to the Fund.

  The Management Agreement continues in effect from year to year only so long as
such continuance is specifically  approved at least annually by the Fund's Board
of Trustees or by vote of a majority of the  outstanding  shares of the Fund. In
either case, the terms of the Management  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  Management
Agreement may be terminated,  without penalty, on 60 days' written notice by the
Fund or Keystone  Management,  or may be terminated by a vote of shareholders of
the  Fund.  The  Management  Agreement  will  terminate  automatically  upon its
assignment.

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

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

  Pursuant to the Advisory Agreement,  Keystone will receive for its services an
annual  fee  representing  85%  of  the  management  fee  received  by  Keystone
Management under its Management Agreement.

  The Advisory  Agreement  continues in effect from year to year only so long as
such continuance is specifically  approved at least annually by the Fund's Board
of Trustees or by vote of a majority of the  outstanding  shares of the 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,  without penalty, on 60 days' written notice by the
Fund, Keystone Management or Keystone, or by a vote of shareholders of the Fund.

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

FUND EXPENSES
  The Fund will pay all of its expenses.  In addition to the investment advisory
and management fees discussed  above,  the principal  expenses which the Fund is
expected to pay include  expenses of certain  Trustees;  its transfer,  dividend
disbursing and shareholder  servicing agent  expenses;  its custodian  expenses;
fees of the  independent  auditors;  as well as legal  counsel  to its  Board of
Trustees;  fees  payable to  government  agencies,  including  registration  and
qualification fees of the Fund and its shares under federal and state securities
laws; and certain extraordinary expenses. In addition each class will pay all of
the  expenses  attributable  to it.  Such  expenses  are  currently  limited  to
distribution  plan  expenses.  The Fund  also  pays its  brokerage  commissions,
interest  charges and taxes. For the fiscal year ended July 31, 1994, the Fund's
Class A shares paid 1.00% of its average net assets in expenses.  For the fiscal
year ended July 31, 1994,  the Fund's Class B and Class C shares each paid 1.75%
of their respective average net assets in expenses.

  For the Fund's  fiscal year ending July 31,  1995,  Keystone  has  voluntarily
limited  expenses of Class A shares to 1.00% of average net assets  annually and
each of Class B and  Class C shares to 1.75% of  average  net  assets  annually.
Thereafter a redetermination of whether to continue these expense limits and, if
so, at what  rates,  will be made.  Keystone  will not be  required  to make any
reimbursement  to the  extent  such  reimbursement  would  result in the  Fund's
inability  to qualify  as a  regulated  investment  company  under the Code.  In
accordance with voluntary  expense  limitations,  for the fiscal year ended July
31, 1994, Keystone reimbursed the Fund $129,577, 92,657 and $76,307 for Class A,
Class B and Class C shares, respectively.

  Capital  charges  and  certain  expenses,  including  a portion  of the Fund's
Distribution Plan fees, are not included in the calculation of the state expense
limitation. This limitation may be modified or eliminated in the future.

  During  the year  ended July 31,  1994,  the Fund paid or accrued to  Keystone
Investor Resource Center, Inc. ("KIRC"), the Fund's transfer and dividend paying
agent,  $18,880 for  certain  accounting  and  printing  services  and paid KIRC
$130,879  for  shareholder  services.  KIRC  is  a  wholly-owned  subsidiary  of
Keystone.

PORTFOLIO MANAGER
  Christopher P. Conkey has been the Fund's portfolio  manager since 1988. He is
a  Keystone  Senior  Vice  President  and Group Head with more than 11 years' of
investment experience.

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

  The Fund may pay higher  commissions to broker-dealers  which provide research
services.  Keystone  may use these  services in advising  the Fund as well as in
advising its other clients.

PORTFOLIO TURNOVER
  The portfolio  turnover rate will vary from year to year.  For the fiscal year
ended July 31, 1993, the portfolio  turnover rate for Class A, Class B and Class
C was 160%. The Portfolio turnover rate for each of Class A, Class B and Class C
for the fiscal  year  ended  July 31,  1994 was 280%.  High  portfolio  turnover
involves  correspondingly  greater  brokerage  commissions and other transaction
costs,  which will be borne  directly  by the Fund as well as  additional  gains
and/or  losses.  The Fund pays  brokerage  commissions  in  connection  with the
writing of options and effecting the closing purchase or sale  transactions,  as
well as for some purchases and sales of portfolio securities.

HOW TO BUY SHARES
  You may purchase shares of the Fund from any broker-dealer  that has a selling
agreement with Keystone Investment Distributors Company (formerly named Keystone
Distributors,   Inc.)  (the  "Principal  Underwriter"),   the  Fund's  principal
underwriter.  The Principal Underwriter,  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 the Fund by
mailing to the Fund c/o Keystone Investor Resource Center,  Inc., 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 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 the Fund will be confirmed at an offering
price equal to the net asset value per share next  determined  after  receipt of
the order in proper form by the Principal Underwriter (generally as of the close
of the Exchange on that day) plus, in the case of Class A shares,  the front end
sales  charge.  Orders  received by dealers or other firms prior to the close of
the Exchange and received by the Principal Underwriter prior to the close of its
business day will be confirmed at the offering  price  effective as of the close
of the  Exchange on that day.  Orders for shares  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.

  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.

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

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

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

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

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

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

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

  Each  class of  shares,  pursuant  to its  Distribution  Plan,  pays an annual
service fee of 0.25% of the Fund's average daily net assets attributable to that
class.  In addition to the 0.25%  service  fee,  the Class B and C  Distribution
Plans  provide for the payment of an annual  distribution  fee of up to 0.75% of
the average net assets  attributable to their respective  classes.  As a result,
income distributions paid by the Fund with respect to Class B and Class C shares
will generally be less than those paid with respect to Class A shares.

  Investors who would rather pay the entire cost of  distribution at the time of
investment,  rather than spreading  such 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 intended length of investment.

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

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

</TABLE>

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

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

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

  The sales charge is paid to the Principal Underwriter,  which in turn normally
reallows  a portion  to your  broker-dealer.  In  addition,  your  broker-dealer
currently will be paid periodic service fees at an annual rate of up to 0.25% of
the average daily net asset value of Class A shares maintained by such recipient
outstanding on the books of the Fund for specified periods.

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

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

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

  Since January 1, 1995 through December 31, 1995 and upon prior notification to
the Principal Underwriter, Class A shares may be purchased at net asset value by
clients of registered  representatives within six months after the redemption of
shares of any registered  open-end investment company not distributed or managed
by Keystone or its affiliates,  where the amount invested represents  redemption
proceeds from such unrelated  registered open-end  investment  company,  and the
shareholder  either (1) paid a front end sales  charge,  or (2) was at some time
subject to, but did not actually  pay, a contingent  deferred  sales charge with
respect to the redemption proceeds.

CLASS A DISTRIBUTION PLAN
  The Fund has adopted a  Distribution  Plan with  respect to its Class A shares
(the "Class A Distribution  Plan") that provides for  expenditures  by the Fund,
currently  limited to 0.25%  annually  of the  average  daily net asset value of
Class A shares,  in connection with the distribution of Class A shares.  Payment
under  the  Class A  Distribution  Plan  are  currently  made  to the  Principal
Underwriter  (which may  reallow  all or part to  others,  such as  dealers)  as
service  fees at an annual  rate of up to 0.25% of the  average  daily net asset
value of Class A shares maintained by the recipients outstanding on the books of
the Fund for specified periods.

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

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

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

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

No deferred sales charge is imposed on amounts redeemed thereafter.

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

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

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

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

  The Principal Underwriter generally reallows to brokers or others a commission
equal to 4.00% of the  price  paid for each  Class B share  sold  plus the first
year's  service fee in advance in the amount of 0.25% of the price paid for each
Class B share sold.  Beginning  approximately  12 months after the purchase of a
Class B share,  the broker or other party will receive service fees at an annual
rate of  0.25% of the  average  daily  net  asset  value  of such  Class B share
maintained by the recipient  outstanding  on the books of the Fund for specified
periods. See "Distribution Plans" below.

  With respect to the Fund's Class B shares only, for the period June 1, 1995 to
August 31, 1995, the Principal  Underwriter will reallow an increased commission
equal  to  4.75%  of the  price  paid  for  each  Class  B share  sold to  those
broker/dealers or others who allow their individual  selling  representatives to
participate in the additional 0.75% commission.

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

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

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

CONTINGENT  DEFERRED  SALES  CHARGE AND WAIVER OF SALES  CHARGES
  Any  contingent  deferred sales charge imposed upon the redemption of Class A,
Class B or Class C shares  is a  percentage  of the  lesser of (1) the net asset
value of the shares  redeemed or (2) the net asset value at the time of purchase
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 such
shares;  (2)  certain  shares  with  respect  to  which  the  Fund did not pay a
commission  on issuance,  including  shares  acquired  through  reinvestment  of
dividend income and capital gains distributions; (3) certain Class A shares held
for more than one or two years,  as the case may be, from the date of  purchase;
(4) Class B shares held more than four  consecutive  calendar years or more than
72 months after the month of purchase, as the case may be; or (5) Class C shares
held  for more  than one year  from  the  date of  purchase.  Upon  request  for
redemption,  shares not subject to the contingent  deferred sales charge will be
redeemed  first.  Thereafter,  shares held the  longest  will be the first to be
redeemed.

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

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

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

ARRANGEMENTS WITH BROKER-DEALERS AND OTHERS
  The  Principal  Underwriter  may,  from  time  to  time,  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 Fund shares.  In addition,  dealers may,  from time to time,  receive
additional  cash payments.  The Principal  Underwriter  may also 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 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 1933 Act.

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

  The Principal  Underwriter  may also pay a transaction fee (up to the level of
payments allowed to dealers for the sale of shares, as described above) to banks
and other financial services firms that facilitate transactions in shares of the
Fund for their clients.

  The   Glass-Steagall   Act  currently  limits  the  ability  of  a  depository
institution  (such as a commercial  bank or a savings and loan  association)  to
become an underwriter  or  distributor  of  securities.  In the event the Glass-
Steagall  Act is deemed  to  prohibit  depository  institutions  from  accepting
payments under the arrangement described above, or should Congress relax current
restrictions  on  depository  institutions,  the Board of Trustees will consider
what action, if any, is appropriate.

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

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

  The NASD limits the amount that a Fund may pay annually in distribution  costs
for the 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
the Fund may pay for such distribution costs to 6.25% of gross share sales since
the inception of the 12b-1  Distribution  Plan,  plus interest at the prime rate
plus 1% on such amounts (less any deferred sales charges paid by shareholders to
the Principal Underwriter) remaining unpaid from time to time.

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

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

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

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

  Unreimbursed  distribution  expenses  at July 31, 1994 for Class B shares were
$1,086,574 (6.10% of net class assets).  Unreimbursed  distribution  expenses at
July 31, 1994 for Class C shares were $995,039 (7.60% of net class assets).

  For the year ended July 31,  1994,  the Fund paid KDI  $43,683,  $152,644  and
$123,555  pursuant  to the  Class A,  Class B and  Class C  Distribution  Plans,
respectively.  The Fund makes no  payments  in  connection  with the sale of its
shares other than the fee paid to its Principal Underwriter.

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

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

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

REDEMPTION OF SHARES IN GENERAL
  At various times,  the Fund may be requested to redeem shares for which it has
not yet received good payment. In such a case, the Fund will mail the redemption
proceeds upon clearance of the purchase  check,  which may take up to 15 days or
more.  Any delay may be avoided by  purchasing  shares  either  with a certified
check or by  Federal  Reserve  or bank  wire of funds  or by EFT.  Although  the
mailing of a redemption check or the wiring or 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,  less any applicable  contingent deferred sales
charge (as described above), will be made within seven days thereafter except as
discussed herein.

  You  may  also  redeem  your  shares  through  broker-dealers.  The  Principal
Underwriter,  acting as agent  for the Fund,  stands  ready to  repurchase  Fund
shares upon orders from  dealers and will  calculate  the net asset value on the
same  terms  as  those  orders  for  the  purchase  of  shares   received   from
broker-dealers  and  described  under  "How  to Buy  Shares."  If the  Principal
Underwriter  has  received  proper  documentation,  it will  pay the  redemption
proceeds,  less any  applicable  deferred  sales  charge,  to the  broker-dealer
placing  the order  within  seven days  thereafter.  The  Principal  Underwriter
charges  no fee for this  service.  Your  broker-dealer,  however,  may charge a
service fee.

  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
EXCHANGE  ACT OF 1934 AND  KIRC'S  POLICIES.  The Fund or KIRC  may  waive  this
requirement,  but  also may  require  additional  documents  in  certain  cases.
Currently,  the  requirement  for a  signature  guarantee  has  been  waived  on
redemptions  of $50,000 or less when 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  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.  You must  complete  the
Telephone  Redemptions section of the application to enjoy 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 herein.

SMALL ACCOUNTS
  Due to the high cost of  maintaining  small  accounts,  the Fund  reserves the
right to redeem your account if its value has fallen below  $1,000,  the current
minimum  investment  level, as a result of your redemptions (but not as a result
of market  action).  You will be  notified  in  writing  and  allowed 60 days to
increase the value of your account to the minimum  investment level. No deferred
sales charges are applied to such redemptions.

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  presented  for  redemption  by any one
shareholder  up to the lesser of  $250,000 or 1% of the Fund's net assets in any
90-day period. 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
would,  to the extent  permitted  by law,  be readily  marketable.  Shareholders
receiving such securities would incur brokerage costs upon the securities' sale.

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 fees.

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

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

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

KEYSTONE AUTOMATED RESPONSE LINE
  KARL  offers  you  specific  fund  account  information  and  price  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
  A shareholder who has obtained the appropriate  prospectus may exchange shares
of the Fund for shares of certain  other  Keystone  America  Funds and  Keystone
Liquid Trust ("KLT") as follows:

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

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

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

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

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

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

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

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

  You may exchange shares for another  Keystone fund for a $10 fee by calling or
writing to Keystone.  The exchange fee is waived for  individual  investors  who
make an exchange using KARL. Shares purchased by check are eligible for exchange
after 15 days. If the shares being  tendered for exchange are still subject to a
deferred sales charge,  such charge will carry over to the shares being acquired
in the exchange  transaction.  The Fund reserves the right,  after providing the
required notice to  shareholders,  to terminate this exchange offer or to change
its terms, including the right to change the fee for any exchange.

  Orders to exchange a certain class of shares of the Fund for the corresponding
class of shares of KLT will be executed by redeeming  the shares of the Fund and
purchasing  the  corresponding  class of shares of KLT at the net asset value of
such 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. 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. 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  shares in any amount  and to redeem up to  $50,000  worth of
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.  You will receive  confirmation
from the Principal Underwriter for every transaction.

  To change the  amount of a Keystone  America  Money Line or to  terminate  the
service  (which  could take up to 30 days),  you must write to KIRC and  include
account numbers.

RETIREMENT PLANS
  The Fund has  various  pension  and  profit-sharing  plans  available  to you,
including  Individual  Retirement Accounts ("IRAs");  Rollover IRAs;  Simplified
Employee Pension Plans ("SEPs"),  Tax Sheltered  Annuity Plans ("TSAs"),  401(k)
Plans; Keogh Plans;  Corporate  Profit-Sharing Plans, Pension and Target Benefit
Plans; Money Purchase Plans and Salary-Reduction  Plans. For details,  including
fees and application forms, call toll free 1-800-247-4075 or write to KIRC.

AUTOMATIC WITHDRAWAL PLAN
  Under an Automatic  Withdrawal  Plan,  if your account 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.  Fixed  withdrawal
payments are not subject to a deferred sales charge.  Excessive  withdrawals may
decrease or deplete the value of your account.  Moreover,  because of the effect
of the applicable  sales charge,  a Class A investor  should not make continuous
purchases of the Fund's shares while  participating in the Automatic  Withdrawal
Plan.

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 and
may result in a lower average cost per share than a less  systematic  investment
approach.

  Prior to participating in dollar cost averaging, you must establish an account
in a  Keystone  America  Fund or a money  market  fund  managed  or  advised  by
Keystone.  You should designate on the application (1) the dollar amount of each
monthly or quarterly investment (minimum $100) you wish to make and (2) the fund
in which  the  investment  is to be made.  Thereafter,  on the  first day of the
designated  month,  an  amount  equal  to the  specified  monthly  or  quarterly
investment will automatically be redeemed from your initial account and invested
in shares of the designated fund. If you are a Class A investor and paid a sales
charge on your  initial  purchase,  the shares  purchased  will be eligible  for
Rights of Accumulation  and the sales charge  applicable to the purchase will be
determined  accordingly.  In  addition,  the value of shares  purchased  will be
included in the total amount required to fulfill a Letter of Intent.  If a sales
charge was not paid on the initial  purchase,  a sales charge will be imposed at
the time of subsequent purchases,  and the value of shares purchased will become
eligible for Rights of Accumulation and Letters of Intent.

TWO DIMENSIONAL INVESTING
  You may elect to have income and capital  gains  distributions  from any class
Keystone America Fund shares you may own automatically  invested to purchase the
same class of shares of any other  Keystone  America  Fund.  You may select this
service on your 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 in the same class of shares that you redeemed at current
net asset value.

PERFORMANCE DATA
  From time to time the Fund may advertise  "total return" and "current  yield".
ALL DATA IS BASED ON HISTORICAL  EARNINGS AND IS NOT INTENDED TO INDICATE FUTURE
PERFORMANCE.  Total return and current  yield are computed  separately  for each
class of shares of the Fund.  Total return refers to 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 or applicable contingent
deferred  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.

  The Fund may  also  include  comparative  performance  data for each  class of
shares in advertising  or marketing the Fund's shares,  such as data from Lipper
Analytical  Services,  Inc.,  Morningstar,  Inc., Standard & Poor's Corporation,
Ibbotson Associates or other industry publications.

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

  Shareholders are entitled to one vote for each full share owned and fractional
votes  for  fractional  shares.  Shares of the Fund vote  together  except  when
required by law to vote  separately  by series or 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  Declaration  of Trust of the  Fund,  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. However, the Fund's Declaration of
Trust provides that shareholders  shall not be subject to any personal liability
for the Fund's obligations and provides indemnification from Fund assets for any
shareholder held personally  liable for the Fund's  obligations.  Disclaimers of
such liability are included in each Fund agreement.

                      ADDITIONAL INVESTMENT INFORMATION

  The Fund may  engage  in the  following  investment  practices  to the  extent
described in the prospectus and the statement of additional information.

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 the 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 the 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.  The 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  purchased  by the 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 the 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 are 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,  the 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, the Fund will invest in them only
if the issuer meets the criteria  established for commercial  paper discussed in
the  Statement  of  Additional  Information  which  limit  such  investments  to
commercial  paper rated A-1 by S&P, Prime-1 by Moodys and F-1 by Fitch Investors
Service, Inc.

REPURCHASE AGREEMENTS
  The 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 Fund only  intends 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 Fund does
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,  the 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
the 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, the Fund would sell securities and agree
to repurchase them at a mutually agreed upon date and price. The 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 the 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
the 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 the 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 the 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  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.

FOREIGN SECURITIES
  The Fund may invest up to 25% of its assets in securities  principally  traded
in securities markets outside the U.S. While investment in foreign securities is
intended to reduce risk by providing further  diversification,  such investments
involve  sovereign  risk in  addition  to the credit and market  risks  normally
associated  with  domestic  securities.  Foreign  investments  may  be  affected
favorably  or  unfavorably  by changes in currency  rates and  exchange  control
regulations.  There may be less publicly  available  information about a foreign
company than about a U.S.  company,  and foreign companies may not be subject to
accounting,   auditing  and  financial   reporting  standards  and  requirements
comparable  to those  applicable to U.S.  companies.  Securities of some foreign
companies are less liquid or more volatile  than  securities of U.S.  companies,
and foreign  brokerage  commissions and custodian fees are generally higher than
in the United States.  Investments in foreign  securities may also be subject to
other risks  different from those  affecting U.S.  investments,  including local
political or economic developments,  expropriation or nationalization of assets,
imposition of  withholding  taxes on dividend or interest  payments and currency
blockage  (which would prevent cash from being brought back to the U.S.).  These
risks are  carefully  considered  by  Keystone  prior to the  purchase  of these
securities.

"WHEN ISSUED" SECURITIES
  The 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 the 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  the  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 the 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.  No  payment  or  delivery  is made by the Fund,
however,  until it  receives  payment or  delivery  from the other  party to the
transaction. The Fund will maintain a separate account of liquid assets equal to
the value of such purchase  commitments  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.  The Fund does not accrue any income on
such securities or currencies  prior to their  delivery.  To the extent the Fund
engages in when issued and delayed delivery transactions,  it will do so for the
purpose of acquiring  portfolio  securities  or currencies  consistent  with its
investment  objective  and  policies  and  not  for the  purpose  of  investment
leverage.  The Fund  currently  does not  intend to  invest  more than 5% of its
assets in when issued or delayed delivery transactions.

LOANS OF SECURITIES TO BROKER-DEALERS
  The Fund may lend  securities  to brokers or 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 the 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.  The 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 the 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,  however,  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
  The  Fund  may  use  derivatives  while  seeking  to  achieve  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  Fund 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. The Fund is permitted to use derivatives for one
or  more of  these  purposes,  although  the  Fund  generally  uses  derivatives
primarily as direct investments in order to enhance yields and broaden portfolio
diversification.  Each of these uses entails  greater  risk than if  derivatives
were used solely for  hedging  purposes.  The Fund uses  futures  contracts  and
related  options as well as forwards  for hedging  purposes.  Derivatives  are a
valuable tool which, when used properly, can provide significant benefit to Fund
shareholders.  Keystone is not an aggressive user of derivatives with respect to
the Fund.  However,  the 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 the 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,  futures, forwards and swaps,
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 "Indexed Commercial Paper" and
"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.  See "Mortgage
Related Securities,"  "Collateralized  Mortgage  Obligations,"  "Adjustable Rate
Mortgage Securities,"  "Stripped Mortgage  Securities,"  "Mortgage Securities --
Special  Considerations,"  and "Other  Asset-Backed  Securities"  and the Fund's
statement of additional information.

  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 the 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 the 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 the 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 the Fund as a
  result of the failure of another party to a derivative (usually referred to as
  a  "counterparty")  to comply with the terms of the derivative  contract.  The
  credit  risk  for  exchange-traded  derivatives  is  generally  less  than for
  privately  negotiated  derivatives,  since the  clearing  house,  which is the
  issuer  or  counterparty  to  each  exchange-traded  derivative,   provides  a
  guarantee of  performance.  This  guarantee  is  supported by a daily  payment
  system (i.e., margin requirements)  operated by the clearing house in order to
  reduce overall credit risk. For privately negotiated derivatives,  there is no
  similar  clearing  agency  guarantee.   Therefore,   the  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,  the Fund's use of
  derivatives  may not always be an effective  means of, and sometimes  could be
  counterproductive to, furthering the Fund's investment objective.

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

  The Fund may only write "covered" options. This means that so long as the 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
the Fund has written  options  against all of its securities  that 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. The Fund does not expect, however, that this will occur.

  The 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. The 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,  the 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. The 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 the 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
securities  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 the 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 the Fund's ability to
use such options to achieve its investment objective.

  OPTIONS  TRADING  MARKETS.  Options in which the Fund will trade are generally
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  the  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, the Fund is subject to the investment  restrictions  described
in this prospectus and in the statement of additional information.

  The staff of the  Securities  and Exchange  Commission is of the view that the
premiums  that the Fund pays for the purchase of unlisted  options and the value
of securities used to cover unlisted  options written by the Fund are considered
to be invested in illiquid  securities or assets for the purpose of  calculating
whether the Fund is in compliance with its policies on illiquid securities.

FUTURES TRANSACTIONS
  The Fund may enter into  currency and other  financial  futures  contracts and
write options on such  contracts.  The Fund intends to enter into such contracts
and related options for hedging  purposes.  The Fund will enter into securities,
currency 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. The 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.

  The Fund may sell or purchase  futures  contracts.  When a futures contract is
sold by the Fund,  the value of the contract will tend to rise when the value of
the underlying  securities or currencies  declines and to fall when the value of
such securities or currencies increases.  Thus, the 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 the 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. The Fund intends to purchase futures contracts in order to fix 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.

  The Fund also intends to purchase  put and call  options on futures  contracts
for hedging purposes. A put option purchased by the Fund would give it the right
to  assume a  position  as the  seller  of a  futures  contract.  A call  option
purchased  by the 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  the Fund to pay a  premium.  In  exchange  for the  premium,  the 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, the Fund's loss will be
limited to the amount of the premium and any transaction costs.

  The 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.  The 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 the Fund will be able to enter  into an  offsetting  transaction
with respect to a particular  contract at a particular  time. If the 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 related options  transactions are intended to enable the
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 the Fund's futures  position did not
correspond to changes in the value of its investments.  This lack of correlation
between the 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 the Fund's futures
position and the  securities  or  currencies  held by or to be purchased for the
Fund.  Keystone will attempt to minimize these risks through  careful  selection
and monitoring of the Fund's futures and options positions.

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

FOREIGN CURRENCY TRANSACTIONS
  As discussed above, the Fund may invest in securities of foreign issuers. When
the 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,  the 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 the Fund
will deliver or receive when the contract is  completed)  is fixed when the Fund
enters into the  contract.  The Fund usually will enter into these  contracts to
stabilize the U.S.  dollar value of a security it has agreed to buy or sell. The
Fund intends to use these contracts to hedge the U.S. dollar value of a security
it already owns, particularly if the Fund expects a decrease in the value of the
currency in which the foreign  security is  denominated.  Although the 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 the
Fund's investments denominated in foreign currencies will depend on the relative
strength of those currencies and the U.S.  dollar,  and the 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 the Fund.
Although the Fund does not currently intend to do so, the Fund may also purchase
and sell  options  related  to foreign  currencies.  The Fund does not intend to
enter into foreign currency transactions for speculation or leverage.

INTEREST RATE TRANSACTIONS (SWAPS, CAPS AND FLOORS).
  If the Fund enters into  interest  rate swap,  cap or floor  transactions,  it
expects to do so primarily for hedging purposes,  which may include preserving a
return or spread on a  particular  investment  or  portion of its  portfolio  or
protecting  against an increase in the price of securities the Fund  anticipates
purchasing at a later date.  The Fund does not intend to use these  transactions
in a speculative manner.

  Interest  rate swaps  involve the exchange by the Fund with  another  party of
their  respective  commitments to pay or receive  interest (e.g., an exchange of
floating rate payments for fixed rate  payments).  Interest rate caps and floors
are similar to options in that the  purchase  of an  interest  rate cap or floor
entitles the  purchaser,  to the extent that a specified  index  exceeds (in the
case of a cap) or falls below (in the case of a floor) a predetermined  interest
rate,  to  receive  payments  of  interest  on a  contractually-based  principal
("notional")  amount from the party selling the interest rate cap or floor.  The
Fund  may  enter  into  interest  rate  swaps,  caps and  floors  on  either  an
asset-based or liability-based  basis,  depending upon whether it is hedging its
assets or liabilities,  and will usually enter into interest rate swaps on a net
basis (i.e.,  the two payment streams are netted out, with the Fund receiving or
paying, as the case may be, only the net amount of the two payments).

  The swap market has grown  substantially in recent years,  with a large number
of banks  and  investment  banking  firms  acting  as  principals  and as agents
utilizing  standardized  swap  documentation.  As a result,  the swap market has
become more established and relatively  liquid.  Caps and floors are less liquid
than swaps.  These transactions also involve the delivery of securities or other
underlying assets and principal.  Accordingly, the risk of loss to the Fund from
interest  rate  transactions  is limited to the net amount of interest  payments
that the Fund is contractually obligated to make.

INDEXED COMMERCIAL PAPER.
  Indexed  commercial  paper may have its principal linked to changes in foreign
currency  exchange  rates  whereby its principal  amount is adjusted  upwards or
downwards (but not below zero) at maturity to reflect  changes in the referenced
exchange rate. A Fund will purchase such  commercial  paper with the currency in
which it is denominated  and, at maturity,  will receive  interest and principal
payments  thereon in that currency,  but the amount of principal  payable by the
issuer at  maturity  will  change in  proportion  to the  change (if any) in the
exchange  rate  between  the two  specified  currencies  between  the  date  the
instrument is issued and the date the instrument matures.  While such commercial
paper entails the risk of loss of principal,  the potential for realizing  gains
as a result of changes in foreign  currency  exchange  rates enables the Fund to
hedge (or cross-hedge) against a decline in the U.S. dollar value of investments
denominated in foreign  currencies  while  providing an attractive  money market
rate of return.

MORTGAGE-RELATED SECURITIES.
  The  mortgage-related  securities in which the Fund may  typically  invest are
securities  representing  interests  in pools  of  mortgage  loans  made to home
owners.  Mortgage-related  securities bear interest at either a fixed rate or an
adjustable  rate  determined  by reference to an index rate.  The mortgage  loan
pools may be assembled for sale to investors  (such as the Fund) by governmental
or private organizations.  Mortgage-related  securities issued by the Government
National Mortgage  Association  ("GNMA") are backed by the full faith and credit
of the U.S.  government;  those issued by Federal National  Mortgage  Associated
("FNMA") and Federal Home Loan Mortgage Corporation ("FHLMC") are not so backed.

  Securities   representing  interests  in  pools  created  by  private  issuers
generally offer a higher rate of interest than securities representing interests
in pools created by governmental issuers because there are no direct or indirect
governmental  guarantees of the underlying mortgage payments.  However,  private
issuers sometimes obtain committed loan facilities,  lines of credit, letters of
credit,  surety  bonds or other forms of  liquidity  and credit  enhancement  to
support  the timely  payment of interest  and  principal  with  respect to their
securities  if the  borrowers  on the  underlying  mortgages  fail to make their
mortgage payments. The ratings of such non-governmental securities are generally
dependent upon the ratings of the providers of such liquidity and credit support
and  would  be  adversely  affected  if the  rating  of  such an  enhancer  were
downgraded.  The  Fund  may  buy  mortgage-related   securities  without  credit
enhancement if the securities meet the Fund's investment standards. Although the
market for mortgage-related securities is becoming increasingly liquid, those of
certain private organizations may not be readily marketable.

  One type of mortgage-related  security is of the "pass-through"  variety.  The
holder of a pass-through  security is considered to own an undivided  beneficial
interest in the underlying  pool of mortgage loans and receives a pro rata share
of the monthly  payments made by the borrowers on their mortgage  loans,  net of
any fees paid to the  issuer or  guarantor  of the  securities.  Prepayments  of
mortgages resulting from the sale,  refinancing or foreclosure of the underlying
properties   are  also  paid  to  the   holders   of  these   securities.   Some
mortgage-related  securities, such as securities issued by GNMA, are referred to
as  "modified  pass-through"  securities.  The holders of these  securities  are
entitled  to the full and  timely  payment of  principal  and  interest,  net of
certain fees, regardless of whether payments are actually made on the underlying
mortgages.   Another  form  of   mortgage-related  security  is a  "pay-through"
security, which is a debt obligation of the issuer secured by a pool of mortgage
loans  pledged as collateral  that is legally  required to be paid by the issuer
regardless of whether payments are actually made on the underlying mortgages.

COLLATERALIZED  MORTGAGE  OBLIGATIONS.  ("CMOs")  are  the  predominant  type of
"pay-through" mortgage-related security. CMOs are designed to reduce the risk of
prepayment for investors by issuing multiple classes of securities,  each having
different  maturities,  interest  rates  and  payment  schedules,  and  with the
principal and interest on the underlying  mortgages  allocated among the several
classes in various  ways.  The  interest  rate may be fixed or  adjustable.  The
collateral  securing the CMOs may consist of a pool of  mortgages,  but may also
consist of  mortgage-backed  bonds or  pass-through  securities.  The  secondary
market  for CMOs is  actively  traded.  CMOs may be issued by a U.S.  government
instrumentality  or agency  or by a  private  issuer.  Although  payment  of the
principal  of, and interest on, the  underlying  collateral  securing  privately
issued  CMOs may be  guaranteed  by GNMA,  FNMA or FHLMC,  these CMOs  represent
obligations  solely of the private  issuer and are not insured or  guaranteed by
GNMA, FNMA, FHLMC, any other governmental agency or any other person or entity.

INVERSE  FLOATING  RATE  COLLATERALIZED  MORTGAGE  OBLIGATIONS.  In  addition to
investing in fixed rate and  adjustable  rate CMOs,  the Fund may also invest in
CMOs 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.

ADJUSTABLE RATE MORTGAGE SECURITIES.  Another type of mortgage-related security,
known as adjustable-rate  mortgage securities ("ARMS"), bears interest at a rate
determined by reference to a predetermined interest rate or index. There are two
main  categories  of rates or  indices:  (1)  rates  based on the  yield on U.S.
Treasury  securities and (2) indices derived from a calculated measure such as a
cost of funds  index or a moving  average  of  mortgage  rates.  Some  rates and
indices closely mirror changes in market interest rate levels, while others tend
to lag changes in market rate levels and tend to be somewhat less volatile.

  ARMS may be secured by adjustable-rate mortgages or fixed-rate mortgages. ARMS
secured by fixed-rate mortgages generally have lifetime caps on the coupon rates
of the  securities.  To the extent that general  interest rates increase  faster
than the  interest  rates on the ARMS,  these ARMS will  decline  in value.  The
adjustable-rate  mortgages that secure ARMS will frequently have caps that limit
the  maximum  amount by which the  interest  rate or the monthly  principal  and
interest  payments on the mortgages may increase.  These payment caps can result
in negative  amortization  (i.e.,  an  increase  in the balance of the  mortgage
loan). Furthermore, since many adjustable-rate mortgages only reset on an annual
basis,  the  values of ARMS tend to  fluctuate  to the  extent  that  changes in
prevailing  interest rates are not  immediately  reflected in the interest rates
payable  on  the  underlying   adjustable-rate   mortgages.

STRIPPED MORTGAGE SECURITIES.  Stripped mortgage-related securities ("SMRS") are
mortgage-related  securities  that are  usually  structured  with two classes of
securities  collateralized by a pool of mortgages or a pool of  mortgaged-backed
bonds  or  pass-through   securities,   with  each  class  receiving   different
proportions of the principal and interest payments from the underlying assets. A
common type of SMRS has one class of interest-only  securities ("IOs") receiving
all of the interest payments from the underlying  assets,  while the other class
of securities,  principal-only securities ("POs"), receives all of the principal
payments from the  underlying  assets.  IOs and POs are  extremely  sensitive to
interest  rate changes and are more volatile  than  mortgage-related  securities
that are not stripped.  IOs tend to decrease in value as interst rates decrease,
while POs generally increase in value as interest rates decrease. If prepayments
of the underlying mortgages are greater than anticipated, the amount of interest
earned on the overall pool will decrease due to the decreasing principal balance
of the assets. Changes in the values of IOs and POs can be substantial and occur
quickly,  such as  occurred in the first half of 1994 when the value of many POs
dropped  precipitously  due to increase in interest  rates.  For this reason the
Fund  does not rely on IOs and POs as the  principal  means  of  furthering  its
investment objective.

  Determinations  of the  liquidity of SMRS issued by the U.S.  government,  its
agencies  and  instrumentalities  will  be  made by  ascertaining  whether  such
securities  can be  disposed  of within  seven  days in the  ordinary  course of
business at the value used in the  calculation of the Fund's net asset value per
share. In the event the Fund purchases Stripped Mortgage  Securities  determined
to be  illiquid  pursuant  to the  guidelines  established  by the  Board,  such
Stripped  Mortgage  Securities,  together  with  investments  in other  illiquid
securities,  will be limited to 15% of the Fund's assets. In any event, the Fund
currently  intends  to invest  no more than 15% of its net  assets in IOs and to
limit investment in POs so that its PO holdings do not exceed its IO holdings by
more than 5%.

MORTGAGE-RELATED   SECURITIES   --   SPECIAL   CONSIDERATIONS.   The   value  of
mortgage-related   securities  is  affected  by  a  number  of  factors.  Unlike
traditional debt securities,  which have fixed maturity dates,  mortgage-related
securities  may be paid earlier than  expected as a result of  prepayment of the
underlying mortgages.  If property owners make unscheduled  prepayments of their
mortgage  loans,  these  prepayments  will  result in the early  payment  of the
applicable mortgage-related  securities. In that event the Fund may be unable to
invest the proceeds from the early payment of the mortgage-related securities in
an investment that provides as high a yield as the mortgage-related  securities.
Consequently,  early payment associated with mortgage-related  securities causes
these securities to experience  significantly greater price and yield volatility
than  experienced  by  traditional  fixed-income  securities.  The occurrence of
mortgage prepayments is affected by the level of general interest rates, general
economic conditions and other social and demographic factors.  During periods of
falling  interest  rates,  the rate of mortgage  prepayments  tends to increase,
thereby  tending to decrease  the life of  mortgage-related  securities.  During
periods of rising  interest  rates,  the rate of  mortgage  prepayments  usually
decreases,  thereby tending to increase the life of mortgage-related securities.
If the life of a mortgage-related  security is inaccurately predicted,  the Fund
may not be able to realize the rate of return it expected.

  As with  fixed-income  securities  generally,  the  value of  mortgage-related
securities can also be adversely affected by increases in general interest rates
relative  to the yield  provided  by such  securities.  Such  adverse  effect is
especially possible with fixed-rate mortgage securities.  If the yield available
on other investments rises above the yield of the fixed-rate mortgage securities
as a result of general  increases  in  interest  rate  levels,  the value of the
mortgage-related  securities will decline. Although the negative effect could be
lessened  if the  mortgage-related  securities  were  to be paid  earlier  (thus
permitting the Fund to reinvest the prepayment proceeds in investments  yielding
the higher  current  interest  rate),  as  described  above the rate of mortgage
prepayments and earlier payment of mortgage-related  securities  generally tends
to decline during a period of rising interest rates.

  Although  the value of ARMS may not be  affected by rising  interest  rates as
much as the  value of  fixed-rate  mortgage  securities  is  affected  by rising
interest  rates,  ARMS may still decline in value as a result of rising interest
rates.  Although,  as described  above, the yield on ARMS varies with changes in
the applicable interest rate or index, there is often a lag between increases in
general  interest  rates  and  increases  in the  yield on ARMS as a  result  of
relatively  infrequent  interest rate reset dates. In addition,  adjustable-rate
mortgages  and ARMS often  have  interest  rate or  payment  caps that limit the
ability of the  adjustable-rate  mortgages or ARMS to fully reflect increases in
the general level of interest rates.

  OTHER ASSET-BACKED SECURITIES.  The securitization  techniques used to develop
mortgage-related  securities  are being  applied to a broad  range of  financial
assets.  Through the use of trusts and  special  purpose  corporations,  various
types of assets, including automobile loans and leases, credit card receivables,
home equity loans, equipment leases and trade receivables, are being securitized
in structures similar to the structures used in mortgage securitizations.  These
asset-backed securities are subject to risks associated with changes in interest
rates  and  prepayment  of  underlying  obligations  similar  to  the  risks  of
investment in mortgage-related securities discussed above.

  Each type of asset-backed  security also entails unique risks depending on the
type of assets involved and the legal  structure used. For example,  credit card
receivables  are generally  unsecured  obligations of the credit card holder and
the debtors  are  entitled  to the  protection  of a number of state and federal
consumer  credit  laws,  many of which  give such  debtors  the right to set off
certain  amounts  owed on the credit  cards,  thereby  reducing the balance due.
There  have also been  proposals  to cap the  interest  rate that a credit  card
issuer may charge. In some transactions,  the value of the asset-backed security
is dependent on the  performance  of a third party acting as credit  enhancer or
servicer.  Furthermore,  in some  transactions  (such  as  those  involving  the
securitization of vehicle loans or leases) it may be administratively burdensome
to perfect the interest of the security issuer in the underlying  collateral and
the underlying collateral may become damaged or stolen.

VARIABLE,   FLOATING  AND  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  represent interests in entities
organized and operated  solely for the purpose of  restructuring  the investment
characteristics of sovereign debt obligations or foreign government  securities.
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 or Brady  Bonds)  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.

BRADY BONDS. Brady Bonds are created through the exchange of existing commercial
bank loans to foreign  entities  for new  obligations  in  connection  with debt
restructurings under a plan introduced by former U.S. Secretary of the Treasury,
Nicholas  F.  Brady (the  "Brady  Plan").  Brady  Bonds  have been  issued  only
recently,  and,  accordingly,  do not have a long payment  history.  They may be
collateralized or  uncollateralized  and issued in various currencies  (although
most  are  U.S.   dollar-denominated)  and  they  are  actively  traded  in  the
over-the-counter secondary market.

  U.S.  dollar-denominated,  collateralized Brady Bonds, which may be fixed-rate
par bonds or floating rate discount bonds, are generally  collateralized in full
as to principal due at maturity by U.S.  Treasury zero coupon  obligations  that
have the same  maturity  as the Brady  Bonds.  Interest  payments on these Brady
Bonds generally are  collateralized  by cash or securities in an amount that, in
the case of fixed rate bonds, is equal to at least one year of rolling  interest
payments based on the  applicable  interest rate at that time and is adjusted at
regular  intervals  thereafter.  Certain  Brady  Bonds  are  entitled  to "value
recovery  payments"  in  certain  circumstances,   which  in  effect  constitute
supplemental  interest  payments,  but generally are not  collateralized.  Brady
Bonds  are  often  viewed  as  having  up  to  four  valuation  components:  (1)
collateralized  repayment  of principal at final  maturity,  (2)  collateralized
interest  payments,   (3)  uncollateralized   interest  payments,  and  (4)  any
uncollateralized  repayment  of principal  at maturity  (these  uncollateralized
amounts  constitute the "residual risk"). In the event of a default with respect
to  collateralized  Brady Bonds as a result of which the payment  obligations of
the issuer are accelerated,  the U.S.  Treasury zero coupon  obligations held as
collateral  for the payment of principal  will not be  distributed to investors,
nor will such obligations be sold and the proceeds  distributed.  The collateral
will be held by the collateral agent to the scheduled  maturity of the defaulted
Brady  Bonds,  which will  continue  to be  outstanding,  at which time the face
amount of the collateral will equal the principal  payments that would have then
been due on the Brady Bonds in the normal course.  In addition,  in light of the
residual risk of Brady Bonds and, among other  factors,  the history of defaults
with  respect  to  commercial  bank  loans by public  and  private  entities  of
countries  issuing Brady Bonds,  investments  in Brady Bonds are to be viewed as
speculative.

EQUIPMENT TRUST  CERTIFICATES.  Equipment Trust Certificates are a mechanism for
financing the purchase of  transportation  equipment,  such as railroad cars and
locomotives, trucks, airplanes and oil tankers.

  Under an equipment  trust  certificate,  the equipment is used as the security
for the debt and title to the  equipment  is vested in a  trustee.  The  trustee
leases the equipment to the user,  i.e. the railroad,  airline,  trucking or oil
company.  At the same time equipment trust  certificates in an aggregate  amount
equal to a certain  percentage  of the  equipment's  purchase  price are sold to
lenders.  The trustee pays the  proceeds  from the sale of  certificates  to the
manufacturer.  In addition,  the company  using the  equipment  makes an initial
payment of rent equal to the balance of the purchase price to the trustee, which
the trustee also pays to the  manufacturer.  The trustee collects lease payments
from the company and uses the  payments to pay  interest  and  principal  on the
certificates. At maturity, the certificates are redeemed and paid, the equipment
is sold to the  company  and the lease is  terminated.  These  certificates  are
typically traded in the over-the-counter market.

  Generally,  these certificates are regarded as obligations of the company that
is leasing the  equipment  and are shown as  liabilities  in its balance  sheet.
However,  the company does not own the equipment until all the  certificates are
redeemed  and paid.  In the event the  company  defaults  under its  lease,  the
trustee terminates the lease. If another lessee is available, the trustee leases
the equipment to another user and makes  payments on the  certificates  from new
lease rentals.

  The  principal  risk of  these  certificates  is the  decline  in value of the
equipment.  However, the equipment which is typically involved is not subject to
rapid decline in value.

ZERO COUPON "STRIPPED" BONDS. A zero coupon "stripped" bond represents ownership
in  serially  maturing  interest  payments  or  principal  payments  on specific
underlying notes and bonds,  including coupons relating to such notes and bonds.
The interest and principal payments are direct obligations of the issuer. Coupon
zero coupon bonds of any series  mature  periodically  from the date of issue of
such series through the maturity date of the securities  related to such series.
Principal zero coupon bonds mature on the date specified  therein,  which is the
final maturity date of the related  Treasury  securities.  Each zero coupon bond
entitles  the  holder to  receive a single  payment  at  maturity.  There are no
periodic  interest payments on a zero coupon bond. Zero coupon bonds are offered
at discounts from their face amounts.

  In general,  owners of zero coupon bonds have substantially all the rights and
privileges  of  owners  of  the  underlying  coupon   obligations  or  principal
obligations.  Owners of zero  coupon  bonds have the right  upon  default on the
underlying coupon  obligations or principal  obligations to proceed directly and
individually  against the issuers  and are not  required to act in concert  with
other holders of zero coupon bonds.

  For federal income tax purposes, a purchaser of principal zero coupon bonds or
coupon  zero coupon  bonds  (either  initially  or in the  secondary  market) is
treated  as if the buyer had  purchased  a  corporate  obligation  issued on the
purchase date with an original  issue discount equal to the excess of the amount
payable at maturity over the purchase  price.  The purchaser is required to take
into account each year as ordinary income an allocable portion of such discounts
determined on a "constant yield" method.  Any such income increases the holder's
tax basis for the zero coupon  bond,  and any gain or loss on a sale of the zero
coupon bonds relative to the holder's basis,  as so adjusted,  is a capital gain
or loss.  If the holder owns both  principal  zero coupon  bonds and coupon zero
coupon bonds representing interest in the same underlying issue of securities, a
special basis  allocation  rule  (requiring the aggregate  basis to be allocated
among the items sold and retained  based on their  relative fair market value at
the time of sale) may apply to determine  the gain or loss on a sale of any such
zero coupon bonds and the subsequent accrual of discount on the retained items.

                            REDUCED SALES CHARGES

  Initial  sales   charges  may  be  reduced  or   eliminated   for  persons  or
organizations purchasing Class A shares of the 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  below.  For example,  if a Purchaser  concurrently  invested
$75,000 in one of the other "Eligible  Funds" and $75,000 in the 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 the 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)"). 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 Sales
Charge  schedule.  KIRC  must be  notified  at the  time of  purchase  that  the
Purchaser is entitled to a reduced sales charge, which reduction will be granted
subject to confirmation of the Purchaser's  holdings.  The Right of Accumulation
may be modified or discontinued at any time.

LETTER OF INTENT
  A Purchaser  may qualify for a reduced  sales  charge on a purchase of Class A
shares of the Fund alone or in  combination  with purchases of Class A shares of
any of the other  Eligible  Funds by completing  the Letter of Intent section of
the  application.  By  so  doing,  the  Purchaser  agrees  to  invest  within  a
thirteen-month  period a specified  amount which, if invested at one time, would
qualify  for a reduced  sales  charge.  Each  purchase  will be made at a public
offering price applicable to a single transaction of the dollar amount specified
on the application,  as described in this prospectus.  The Letter of Intent does
not  obligate  the  Purchaser  to  purchase,  nor 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 the  Principal
Underwriter any difference  between the sales charge on the amount specified and
on the amount actually attained.  If the Purchaser does not within 20 days after
written  request by the Principal  Underwriter or his dealer pay such difference
in sales charge,  KIRC will redeem an appropriate  number of the escrowed shares
in order to realize such difference.  Shares remaining after any such redemption
will be released  by KIRC.  Any  redemptions  made by the  Purchaser  during the
thirteen-month  period will be  subtracted  from the amount of the purchases for
purposes of determining whether the Letter of Intent has been completed.  In the
event of a total  redemption of the account prior to completion of the Letter of
Intent,  the  additional  sales charge due will be deducted from the proceeds of
the redemption and the balance will be forwarded to the Purchaser.

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

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

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

         The Fund is an  open-end  diversified,  management  investment  company
commonly  known as a mutual  fund.  The Fund seeks  current  income by investing
primarily in investment quality debt securities.  As a secondary objective,  the
Fund seeks to protect capital.  The Fund was formed as a Massachusetts  business
trust on October  24,  1986.  The Fund is managed by Keystone  Management,  Inc.
("Keystone  Management") and advised by Keystone  Investment  Management Company
(formerly named Keystone Custodian Funds, Inc.)
("Keystone").

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


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

         The Fund invests  primarily  in  investment  quality  debt  securities.
Certain  investments and investment  techniques,  including the risks associated
with such investments and investment techniques, and ratings criteria applicable
to the Fund are more  fully  explained  in the  Appendix  to this  statement  of
additional information.

FUNDAMENTAL NATURE OF INVESTMENT OBJECTIVE

         The  investment  objective  of the Fund is  fundamental  and may not be
changed without approval of the holders of a majority of the 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 and may
not be changed without the vote of a majority of the Fund's  outstanding  voting
shares. Unless otherwise stated, all references to the assets of the Fund are in
terms of current market value.

         The Fund may not do the following:

         (1) purchase any security (other than United States ("U.S.") government
securities) of any issuer, if as a result more than 5% of its total assets would
be invested  in  securities  of the  issuer,  except that up to 25% of its total
assets may be invested without regard to this limit;

         (2)  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;

         (3) 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;

         (4) borrow money or enter into reverse  repurchase  agreements,  except
that the 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
exceed 5% of the Fund's net assets,  any such  borrowings  will be repaid before
additional investments are made;

         (5) 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;

         (6) 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;

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

         (8) purchase any security  (other than U.S.  government  securities) of
any issuer if as a result more than 25% of its total assets would be invested in
a single  industry;  except  that (a) there is no  restriction  with  respect to
obligations  issued  or  guaranteed  by the U.S.  government,  its  agencies  or
instrumentalities;  (b) wholly-owned  finance companies will be considered to be
in the industries of their parents if their activities are primarily  related to
financing the  activities  of the parents;  (c) the industry  classification  of
utilities will be determined according to their services (for example,  gas, gas
transmission,  electric  and  telephone  will  each  be  considered  a  separate
industry);  and (d) the industry  classification of medically related industries
will be  determined  according  to  their  services  (for  example,  management,
hospital supply, medical equipment and pharmaceuticals will each be considered a
separate industry);

         (9)  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;

         (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;
and

         (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.

         The Fund  intends to follow  policies of the  Securities  and  Exchange
Commission  as they are  adopted  from time to time  with  respect  to  illiquid
securities,  including, at this time, (1) treating as illiquid, securities which
may not be sold or disposed of in the ordinary  course of business  within seven
days at  approximately  the value at which the Fund has valued the investment on
its books and (2) limiting its holdings of such securities to 15% of net assets.

         As a matter of practice the Fund treats reverse  repurchase  agreements
as borrowings for purposes of compliance  with the limitations of the Investment
Company Act of 1940 ("1940 Act.") Reverse  repurchase  agreements  will be taken
into account along with  borrowings  from banks for purposes of the 5% limit set
forth in Investment Restriction (4).

         Additional  restrictions  adopted by the Fund,  which may be changed by
the  Board  of  Trustees,  provide  that the Fund  may not  purchase  or  retain
securities of an issuer if, to the knowledge of the Fund,  any officer,  Trustee
or Director 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 the Fund may not be purchased  from or sold or
loaned to Keystone or any affiliate thereof or any of their Directors,  officers
or employees.

         Although  not  fundamental   restrictions   or  policies   requiring  a
shareholders'  vote to change,  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 (1) will not invest in interests
in oil,  gas or  other  mineral  exploration  or  development  programs,  except
publicly traded  securities of companies  engaging in such activities,  (2) will
not write or sell puts, calls or combinations thereof,  except that it may write
covered  put and call  options,  (3) in  connection  with the  purchase  of debt
securities,  may acquire warrants or other rights to subscribe for securities of
issuers or securities  of parents or  subsidiaries  of such issuers  (warrants),
provided  that no more than 5% of its total  assets may be  invested in warrants
(for the purpose of this restriction,  warrants attached to securities  acquired
by the Fund may be deemed to be without value);  in any case,  unless authorized
by the vote of a majority of the Fund's outstanding voting shares.

         As a continuing  condition of registration of the Fund in a state,  the
Fund has undertaken not to purchase any securities  (other than U.S.  government
securities)  of any  issuer  if, as a result,  more than 5% of its total  assets
would be invested in securities of the issuer.

         Although  not  fundamental   restrictions   or  policies   requiring  a
shareholders'  vote to change,  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 not (1) write  puts and
calls on  securities  unless  (a) the option is issued by the  Options  Clearing
Corporation,  (b)  the  security  underlying  the  put or  call  is  within  the
investment  policies of the Fund, and (c) the aggregate  value of the securities
underlying the calls or obligations  underlying the puts  determined,  as of the
date of sale,  does not exceed 25% of its net assets,  and (2) buy and sell puts
and calls  written  by others  unless (a) the  options  are listed on a national
securities or commodities  exchange or offered through certain approved national
securities  associations,  and (b) the  aggregate  premiums paid on such options
held at any time do not exceed 20% of the Fund's net assets.

         Although  not  fundamental   restrictions   or  policies   requiring  a
shareholders'  vote to change,  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) limit its purchase of
warrants to 5% of net assets,  of which 2% may be warrants not listed on the New
York  or  American  Stock  Exchange,  (2) not  invest  in  real  estate  limited
partnership interests and (3) not invest in oil, gas or other mineral leases.

         In order to permit the sale of Fund 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 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.


- --------------------------------------------------------------------------------
                              DIVIDENDS AND TAXES
- --------------------------------------------------------------------------------

         The Fund distributes to its shareholders  dividends from net investment
income and net realized  long-term and short-term  capital gains annually.  Fund
distributions  are made in additional  shares of that class of shares upon which
the  distribution  is based  or,  at the  option  of the  shareholder,  in cash.
Shareholders who have not opted,  prior to the record date for any distribution,
to receive cash will have the number of  distributed  shares  determined  on the
basis of the Fund's net asset value per share  computed at the end of the day on
the record date after adjustment for the  distribution.  Net asset value is used
in  computing  the  number  of  shares in both  gains  and  income  distribution
reinvestments. Account statements and/or checks as appropriate will be mailed to
shareholders within seven days after the Fund pays the distribution.  Unless the
Fund receives  instructions to the contrary from a shareholder before the record
date, it will assume that the  shareholder  wishes to receive that  distribution
and future gains and income  distributions in shares.  Instructions  continue in
effect until changed in writing.

         Distributed  long-term  capital  gains  are  taxable  as  such  to  the
shareholder  and  regardless of the period of time Fund shares have been held by
the  shareholder.  However,  if such  shares  are held less than six  months and
redeemed at a loss, the  shareholder  will recognize a long term capital loss on
such shares to the extent of the long term capital gain distribution received in
connection  with such  shares.  If the net asset  value of the Fund's  shares is
reduced  below  a  shareholder's  cost by a  capital  gains  distribution,  such
distribution,  to the extent of the  reduction,  would be a return of investment
though taxable as stated above. Since distributions of capital gains depend upon
profits  actually  realized from the sale of securities by the Fund, they may or
may not occur. The foregoing  comments relating to the taxation of dividends and
distributions  paid  on the  Fund's  shares  relate  solely  to  federal  income
taxation.  Such  dividends  and  distributions  may also be subject to state and
local taxes.

         When the Fund makes a  distribution,  it intends to distribute only the
Fund's net capital gains and such income as has been  predetermined  to the best
of the Fund's ability to be taxable as ordinary income. Shareholders of the Fund
will be advised annually of the federal income tax status of distributions.


- --------------------------------------------------------------------------------
                            VALUATION OF SECURITIES
- --------------------------------------------------------------------------------

         Current  values for the Fund's  portfolio  securities are determined as
follows:

         (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) 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  and  which  reflects  fair  value  as
determined by the Fund's Board of Trustees;

         (3)  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;

         (4) short-term  investments  having maturities of more than sixty days,
for which market quotations are readily available,  are valued at current market
value; and

         (5) the  following are valued at prices deemed in good faith to be fair
under  procedures  established by the Fund's Board of Trustees:  (a) securities,
including restricted  securities,  for which complete 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 fixed income securities.  As a result,
depending on the particular securities owned by the Fund, it is likely that most
of the  valuations  for such  securities  will be based  upon  their  fair value
determined  under  procedures  which have been  approved by the Fund's  Board of
Trustees.  The Fund's  Board of  Trustees  has  authorized  the use of a pricing
service to determine the fair value of its fixed income  securities  and certain
other  securities.  Securities for which market quotations are readily available
are valued on a consistent  basis at that price quoted which,  in the opinion of
the Board of Trustees or the person  designated by the Board of Trustees to make
the  determination,  most nearly  represents  the market value of the particular
security.  Any securities for which market  quotations are not readily available
or other assets are valued on a consistent  basis at fair value as determined in
good faith using methods prescribed by the Fund's Board of Trustees.

                                   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 the
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 the Fund, Keystone Management or Keystone is
considered  to be in  addition  to and not in lieu of  services  required  to be
performed  by Keystone  Management  under its  Investment  Management  Agreement
("Management Agreement") with the Fund or Keystone under its Investment Advisory
Agreement ("Advisory  Agreement") with Keystone Management.  The cost, value and
specific  application  of such  information  are  indeterminable  and  cannot be
practically allocated among the Fund and other clients of Keystone Management or
Keystone who may indirectly  benefit from the availability of such  information.
Similarly,  the Fund may indirectly benefit from information made available as a
result of  transactions  effected for such other  clients.  Under the Management
Agreement  and the  Advisory  Agreement,  Keystone  Management  and Keystone are
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  Management and Keystone do follow such a practice,
they will do so on a basis which is fair and equitable to the Fund.

         The Fund expects that purchases and sales of income securities  usually
will be principal transactions.  Such securities 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 the 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,  the Fund will deal with  primary  market  makers
unless more favorable prices are otherwise obtainable.

         The 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  Management,  Keystone  nor the Fund  intend to place
securities transactions with any particular  broker-dealer or group thereof. The
Fund's Board of Trustees  has  determined,  however,  that the Fund 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 Fund are made  independently  by Keystone
Management  or Keystone  from those of the other funds and  investment  accounts
managed by Keystone  Management or Keystone.  It may frequently develop that the
same  investment  decision  is  made  for  more  than  one  fund.   Simultaneous
transactions  are  inevitable  when  the  same  security  is  suitable  for  the
investment  objective  of more  than  one  account.  When  two or more  funds or
accounts  are  engaged  in the  purchase  or  sale  of the  same  security,  the
transactions  are allocated as to amount in  accordance  with a formula which is
equitable  to each fund or  account.  It is  recognized  that in some cases this
system could have a detrimental effect on the price or volume of the security as
far as the Fund is concerned.  In other cases,  however, it is believed that the
ability of the 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  Management,  Keystone,  the  Principal  Underwriter  or any  of  their
affiliated  persons, as defined in the 1940 Act and rules and regulations issued
thereunder.

         For the fiscal years ended July 31, 1992,  1993 and 1994, the Fund paid
no brokerage commissions.

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

GENERAL

         Generally,  the 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
("Front End Load Option"). Class B shares purchased on or after June 1, 1995 are
subject to a contingent deferred sales charge payable upon redemption during the
72 month period following the month of purchase.  Class B shares purchased prior
to June  1,  1995  are  subject  to a  contingent  deferred  sales  charge  upon
redemption within three calendar years following the year of purchase ("Back End
Load Option").  Class B shares purchased on or after June 1, 1995 that have been
outstanding  eight  years  following  the month of purchase  will  automatically
convert to Class A shares  without  imposition  of a front-end  sales  charge or
exchange  fee.  Class B shares  purchased  prior to June 1,  1995 that have been
outstanding  during  seven  calendar  years  will  similarly  convert to Class A
shares.  (Conversion of Class B shares  represented by stock  certificates  will
require  the return of the stock  certificates  to  Keystone  Investor  Resource
Center, Inc., the Fund's transfer and dividend disbursing agent ("KIRC").) Class
C shares are sold subject to a  contingent  deferred  sales charge  payable upon
redemption within one year after purchase ("Level Load Option").  Class C shares
are available  only through  dealers who have entered into special  distribution
agreements  with the Principal  Underwriter.  The 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 that may apply to subsequent purchases;  and a description of applicable
contingent deferred sales charges.

CONTINGENT DEFERRED SALES CHARGES

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

CLASS A SHARES

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

CLASS B SHARES

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

         With  respect to Class B shares  purchased  prior to June 1, 1995,  the
Fund,  with certain  exceptions,  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 you. The deferred sales charge is retained by the
Principal  Underwriter.  Amounts received by the Principal Underwriter under the
Class B Distribution Plans are reduced by deferred sales charges retained by the
Principal Underwriter. See "Calculation of Contingent Deferred Sales charges and
Waiver of Sales Charges" below.

CLASS C SHARES

         With certain  exceptions,  the Fund will 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 the  Principal  Underwriter.  See
"Calculation of Contingent Deferred Sales Charge" below.

CALCULATION OF CONTINGENT DEFERRED SALES CHARGE

         Any  contingent  deferred  sales charge  imposed upon the redemption of
Class A, Class B or Class C shares is a percentage  of the lesser of (1) the net
asset value of the shares redeemed or (2) the net 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 the Fund;  (2)
certain  shares  with  respect  to which  the Fund did not pay a  commission  on
issuance,  including shares acquired through reinvestment of dividend income and
capital gains  distributions;  (3) certain Class A shares held for more than one
or two years, as the case may be, from the date of purchase;  (4) Class B shares
held during  more than four  consecutive  calendar  years or more than 72 months
after the month of purchase,  as the case may be; or (5) Class C shares held for
more than one year from the date of purchase.

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

WAIVER OF SALES CHARGES

         Shares  of the Fund  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  certain  Directors,
Trustees,  officers,  full-time employees and sales representatives of the Fund,
Keystone   Management,   Keystone,   Keystone   Investments,   Inc.   ("Keystone
Investments"),  their subsidiaries and the Principal Underwriter,  who have been
such for not less than ninety days, and to the pension and profit-sharing  plans
established  by such  companies,  their  subsidiaries  and  affiliates,  for the
benefit of their officers,  Trustees,  Directors,  full-time employees and sales
representatives,  and to registered  representatives  of firms which have dealer
agreements with the Principal Underwriter, provided all such sales are made upon
the written  assurance of the purchaser 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 purchases of shares of the 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 the Fund or any fund
in the Keystone  Investments Family of Funds pursuant to this waiver is at least
$500,000 and any  commission  paid at the time of such purchase is not more than
1% of the amount invested.  In addition,  no contingent deferred sales charge is
imposed on redemptions of such shares.

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

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

REDEMPTION OF SHARES

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


- --------------------------------------------------------------------------------
                               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.

DISTRIBUTION PLANS IN GENERAL

         The NASD 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  which  the Fund may pay for  such  distribution  costs to 6.25% of gross
share sales since the  inception of the 12b-1 Plan,  plus  interest at the prime
rate plus 1% on such amounts (less any contingent deferred sales charges paid by
shareholders to the Principal Underwriter).

CLASS A DISTRIBUTION  PLAN. The Class A Distribution Plan provides that the Fund
may expend daily amounts at an annual rate, which is currently  limited to up to
0.25% 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  its  shares,  including,  without  limitation,  expenditures  consisting  of
payments to the  principal  underwriter  of the Fund  (currently  the  Principal
Underwriter)  to  enable  the  Principal  Underwriter  to pay 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 the  Fund  under  the  Class A  Distribution  Plan are
currently used to pay others, such as dealers, service fees at an annual rate of
up to 0.25% of the average net asset value of Class A shares  maintained by such
others outstanding on the books of the Fund for specific periods.

CLASS B DISTRIBUTION PLAN. The Fund has adopted Distribution Plans for its Class
B shares. Each 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 to finance any activity that is primarily
intended to result in the sale of Class B shares, including, without limitation,
expenditures consisting of payments to the Principal Underwriter,  (1) to enable
the Principal  Underwriter to pay to others (dealers)  commissions in respect of
Class B shares since inception of the  Distribution  Plan; and (2) to enable the
Principal  Underwriter  to pay or to have paid to others a service  fee, at such
intervals as the  Principal  Underwriter  may  determine,  in respect of Class B
shares  maintained by any such  recipients  outstanding on the books of the Fund
for specified periods.

         The  Principal  Underwriter  generally  reallows to brokers or others a
commission equal to 4.00% of the price paid for each Class B share sold plus the
first year's service fee in advance in the amount of 0.25% of the price paid for
each Class B share sold. Beginning approximately 12 months after the purchase of
a Class B share,  the broker or other party  receives  service fees at an annual
rate of  0.25% of the  average  daily  net  asset  value  of such  Class B share
maintained by the recipient  outstanding  on the books of the Fund for specified
periods.

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

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

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

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

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

DISTRIBUTION PLANS - GENERAL

         Whether any expenditure under a Distribution Plan is subject to a state
expense  limit will depend upon the nature of the  expenditure  and the terms of
the state law,  regulation or order  imposing the limit. A portion of the Fund's
Distribution  Plan  expenses may be  includable  in the Fund's  total  operating
expenses for purposes of determining compliance with the expense limit.

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

         Any change in a Distribution  Plan that would  materially  increase the
distribution  expenses of the Fund provided for in a Distribution  Plan requires
Shareholder  approval.  Otherwise,  a  Distribution  Plan may be  amended by the
Trustees,  including the Rule 12b-1 Trustees.  Unpaid distribution costs at July
31, 1994, for Class B and Class C shares were $1,086,574 (% of net class assets)
and $995,039 (% of net class assets), respectively.

         While a  Distribution  Plan is 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 the Fund under the foregoing arrangements may
not exceed the maximum Plan limit specified  above.  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 the 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
the Fund's shares  resulting  from payments  under the Plans have  benefited the
Fund.

         For the fiscal  year ended  July 31,  1994 the Fund paid the  Principal
Underwriter $43,683,  $152,644 and $123,555 under the Class A, Class B and Class
C Distribution Plans, respectively.  This amount was used to pay commissions and
service fees.

                               INVESTMENT MANAGER
- --------------------------------------------------------------------------------

         Subject to the general  supervision  of the Fund's  Board of  Trustees,
Keystone  Management,  located at 200  Berkeley  Street,  Boston,  Massachusetts
02116-5034,  serves as investment manager to the Fund and is responsible for the
overall  management  of the Fund's  business and affairs.  Keystone  Management,
organized in 1989,  is a  wholly-owned  subsidiary of Keystone and its directors
and principal executive officers have been affiliated with Keystone,  a seasoned
investment  adviser,  for a number of years.  Keystone Management also serves as
investment manager to most of the other funds in the Keystone Fund Family and to
certain other funds in the Keystone Investments Family of Funds.

         Except as otherwise noted below,  pursuant to the Management  Agreement
with the Fund,  and subject to the  supervision of the Fund's Board of Trustees,
Keystone  Management  manages and  administers  the  operation of the Fund,  and
manages the investment and  reinvestment of the Fund's assets in conformity with
the Fund's  investment  objectives and  restrictions.  The Management  Agreement
stipulates that Keystone  Management  shall provide office space,  all necessary
office facilities, equipment and personnel in connection with its services under
the Management  Agreement and pay or reimburse the Fund for the  compensation of
Fund officers and trustees who are affiliated  with the  investment  manager and
will pay all expenses of Keystone  Management  incurred in  connection  with its
investment  advisory  services.  All  charges  and  expenses  other  than  those
specifically  referred to as being borne by Keystone  Management 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
Plan; taxes and trust fees payable to governmental  agencies;  the cost 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  shareholder's  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.

         The Management  Agreement permits Keystone  Management to enter into an
agreement with Keystone or another investment  adviser,  under which Keystone or
such other investment adviser, as investment adviser, will provide substantially
all the  services to be provided by  Keystone  Management  under the  Management
Agreement. The Management Agreement also permits Keystone Management to delegate
to Keystone or another  investment  adviser  substantially all of the investment
manager's  rights,  duties  and  obligations  under  the  Management  Agreement.
Services performed by Keystone  Management  include (1) performing  research and
planning with respect to (a) the Fund's  qualification as a regulated investment
company  under  Subchapter  M of the  Code,  (b)  tax  treatment  of the  Fund's
portfolio  investments,  (c) tax treatment of special corporate actions (such as
reorganizations),  (d) state tax matters  affecting the Fund, and (e) the Fund's
distributions  of income and capital gains; (2) preparing the Fund's federal and
state  tax  returns;  (3)  providing  services  to the  Fund's  shareholders  in
connection  with  federal and state  taxation  and  distributions  of income and
capital gains; and (4) storing documents relating to the Fund's activities.

         The Fund pays Keystone  Management a fee for its services at the annual
rate of:

                                                       Aggregate Net Asset Value
Management                                                         of the Shares
Fee                            Income                                of the Fund
- --------------------------------------------------------------------------------
                              2.0% of
                         Gross Dividend and
                          Interest Income
                                Plus
0.50%     of the first                                     $  100,000,000, 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.

         For one year beginning January 1, 1994, Keystone will limit expenses of
Class A shares to 1.00% annually and each of Class B and Class C shares to 1.75%
annually.  Thereafter a  redetermination  of whether to continue  these  expense
limits  and,  if so, at what  rates,  will be made.  In  accordance  with  these
voluntary expense limitations, for the fiscal year ended July 31, 1994, Keystone
reimbursed the Fund $129,577,  $92,657,  and $76,307  respectively,  for Class A
Shares, Class B Shares and Class C Shares.

         As a  continuing  condition  of  registration  of  shares  in a  state,
Keystone  has  agreed to  reimburse  the Fund  annually  for  certain  operating
expenses  incurred  by the Fund in excess of certain  percentages  of the Fund's
average  daily net  assets.  Keystone  is not  required,  however,  to make such
reimbursements  to an extent  which  would  result in the  Fund's  inability  to
qualify as a regulated  investment  company  under  provisions  of the  Internal
Revenue Code. This condition may be modified or eliminated in the future.

         The Management  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,  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 Management 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.  The  Management
Agreement will terminate  automatic-ally  upon its  "assignment" as that term is
defined in the 1940 Act.

         For  additional  discussion  of fees paid to Keystone  Management,  see
"Investment Adviser" below.

subject to the supervision of the Fund's Board of Trustees, Keystone manages and
administers   the  operation  of  the  Fund,  and  manages  the  investment  and

or reimburse the Fund for the compensation of Fund officers and trustees who are
affiliated  with the  investment  manager and will pay all  expenses of Keystone
incurred in connection with its investment  advisory  services.  All charges and

charges and  expenses of legal  counsel for the Fund and for the Trustees of the

         During the fiscal years ended July 31,  1992,  the Fund paid or accrued
to Keystone Management investment management and administrative services fees of
$140,733,  which  represented  0.70%, of the Fund's average net assets.  Of such
amount  paid  to  Keystone  Management,  $119,623,  was  paid  to  Keystone  for
investment  advisory  services under the Investment  Advisory  Agreement between
Keystone Management and Keystone.

         During the fiscal year ended July 31, 1993, the Fund paid or accrued to
Keystone Management  investment  management and administrative  services fees of

to Keystone for its services to the Fund.

         During the fiscal year ended July 31, 1994, the Fund paid or accrued to

and  Class  C  shares,  respectively.  From  time  to  time  in  the  future,  a
redetermination  of whether to continue the expense  limitations  and, if so, at
what rate,  will be made. In any event,  Keystone  would not be required to make
such  reimbursement  to the extent which would result in the Fund's inability to
qualify as a regulated investment company under the Internal Revenue Code.


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

         The Fund has  entered  into a  Principal  Underwriting  Agreement  (the
"Underwriting  Agreement")  with  the  Principal  Underwriter,   a  wholly-owned
subsidiary of Keystone.

         The  Principal  Underwriter,  located at 200 Berkeley  Street,  Boston,
Massachusetts, 02116-5034, is a Delaware corporation. The Principal Underwriter,
as agent, currently has the right to obtain subscriptions for and to sell shares
of the Fund to the public. In so doing, the Principal Underwriter may retain and
employ  representatives  to  promote  distribution  of the shares and may obtain
orders  from  brokers,  dealers or others,  acting as  principals,  for sales of
shares.  No such  representative,  dealer or broker has any  authority to act as
agent for the Fund.  The Principal  Underwriter  has not undertaken to buy or to
find purchasers for any specific number of shares. The Principal Underwriter may
receive payments from the Fund pursuant to the Distribution Plans.

         All subscriptions and sales of shares by the Principal  Underwriter are
at the offering  price of the shares,  such price being 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 its shares with the Commission and
auditing and filing fees in connection with registration of its shares under the
various state "blue-sky" laws.

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

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

         The  Underwriting  Agreement  provides that it will remain in effect as
long as its terms and  continuance  are  approved  by a  majority  of the Fund's
Independent Trustees at least annually at a meeting called for that purpose, and
if its continuance is approved annually by vote of a majority of Trustees, or by
vote of a majority of the outstanding shares.

         The Underwriting  Agreement may be terminated,  without penalty,  on 60
days'  written  notice by the Board of  Trustees  or by a vote of a majority  of
outstanding shares. The Underwriting Agreement will terminate automatically upon
its "assignment" as that term is defined in the 1940 Act.


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

MASSACHUSETTS BUSINESS TRUST

         The  Fund  is  a  Massachusetts  business  trust  established  under  a
Declaration  of Trust  dated  October  24,  1986.  The Fund is  similar  in most
respects to a business  corporation.  The principal distinction between the Fund
and a corporation  relates to the shareholder  liability described below. A copy
of the Declaration of Trust is filed as an exhibit to the Registration Statement
of which this  statement of additional  information  is a part.  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 the Fund
represents an equal proportionate  interest with each other share of that class.
Upon  liquidation,  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  redeemable  and  transferable.   The  Fund  is
authorized to issue additional classes or series of shares.  Generally, the Fund
currently issues three classes of shares,  but may issue  additional  classes or
series of shares.

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. Even if, however, 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  contains  an express  disclaimer  of
shareholder  liability for  obligations  of the Fund and 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 because the  Declaration  of
Trust 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.
However at meetings  called for the initial  election of trustees or to consider
other matters,  shares are entitled to one vote per share. Shares generally vote
together as one class on all  matters.  Classes of shares of the Fund have equal
voting rights except that each class of shares has exclusive  voting rights with
respect to its respective  Distribution Plan.  However, no amendment may be made
to the Declaration of Trust which adversely  affects any class of shares without
the  approval  of  a  majority  of  the  shares  of  that  class.   Shares  have
non-cumulative  voting rights,  which means that the holders of more than 50% of
the shares voting for the election of Trustees can elect 100% of the Trustees to
be elected at a meeting and, in such event,  the holders of the remaining 50% or
less of the shares voting will not be able to elect any Trustees.

         After an initial  meeting as described  above,  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 will not be liable for
errors of judgment or mistakes of fact or law, but nothing in the Declaration of
Trust  protects a Trustee  against any liability to which he would  otherwise be
subject  by reason of  willful  misfeasance,  bad  faith,  gross  negligence  or
reckless disregard of his duties involved in the conduct of his office.

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

         Total return  quotations  for a class of shares of the 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 the maximum  sales
charge 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  cumulative  total  return  of Class A  annualized  for the  period
beginning April 14, 1987  (commencement of investment  operations)  through July
31, 1994 was 48.52%. The cumulative total return of Class A for the one and five
years ended July 31, 1994 were (5.02)% and 35.45%, respectively.  The compounded
average  annual rate of return for Class A for the period April 14, 1987 through
July 31, 1994 was 5.57%. The compounded  average annual rate of return for Class
A for the five years ended July 31, 1994 was 6.26%.  The cumulative total return
of Class B and Class C  annualized  for the period  beginning  February  1, 1993
(commencement  of  operations)  through  July 31,  1994  was  0.48%  and  3.32%,
respectively.  The  cumulative  total  return of Class B and Class C for the one
year  period  ended July 31, 1994 was (3.86)%  and  (0.95)%,  respectively.  The
compounded  average  annual  rate of return for the  Fund's  Class B and Class C
annualized  for the period from February 1, 1993  (commencement  of  operations)
through July 31, 1994 was (1.05)% and (0.95)%, 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 the 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.  The Fund's  current  yields
for Class A, Class B and Class C for the 30-day  period ended July 31, 1994 were
5.83%, 5.36% and 5.36%, respectively.

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

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

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.

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.

    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,  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,  or of savings and loan associations
and have at least $1  billion  in assets as of the date of their  most  recently
published financial statements.

    The Fund  will not  acquire  time  deposits  or  obligations  issued  by the
International  Bank for  Reconstruction  and Development,  the Asian Development
Bank or the  Inter-American  Development Bank.  Additionally,  the Fund does not
currently intend to purchase such 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 the Fund  must have  been  accepted  by U.S.
commercial banks,  including foreign branches of U.S.  commercial banks,  having
total assets 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 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  passthrough  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 Series 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,  the 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
<PAGE>
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.

                             CORPORATE BOND RATINGS

S&P CORPORATE BOND RATINGS

    An S&P corporate 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-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.  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 BOND RATINGS

    Moody's ratings are as follows:

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

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


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

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

    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.

                              OPTIONS TRANSACTIONS

WRITING COVERED OPTIONS

    The Fund  writes  only  covered  options.  Options  written by the Fund will
normally  have  expiration  dates of not more  than  nine  months  from the date
written.  The exercise price of the options may be below, equal to, or above the
current market values of the underlying  securities at the times the options are
written.

    Unless the option  has been  exercised,  the Fund may close out an option it
has written by effecting a closing purchase transaction, whereby it purchases an
option covering the same underlying  security and having the same exercise price
and  expiration  date ("of the same  series") as the one it has written.  If the
Fund  desires  to sell a  particular  security  on which it has  written  a call
option,  it will effect a closing purchase  transaction prior to or concurrently
with the sale of the  security.  If the  Fund is able to  enter  into a  closing
purchase  transaction,  the Fund  will  realize  a profit  (or  loss)  from such
transaction  if the cost of such  transaction is less (or more) than the premium
received from the writing of the option.

    An option  position  may be closed  out only in a  secondary  market  for an
option of the same  series.  Although the Fund will  generally  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.  If the Fund as a  covered  call  option  writer  is  unable to effect a
closing  purchase  transaction,  it will  not be able  to  sell  the  underlying
securities  until the option  expires or it delivers the  underlying  securities
upon exercise.

    Because the Fund intends to qualify as a regulated  investment company under
the Internal  Revenue Code,  the extent to which the Fund may write covered call
options and enter into so-called "straddle"  transactions involving put and call
options may be limited.

    Many options are traded on registered securities  exchanges.  Options traded
on such  exchanges  are issued by the  Options  Clearing  Corporation  (OCC),  a
clearing corporation which assumes  responsibility for the completion of options
transactions.


PURCHASING PUT AND CALL OPTIONS

    The Fund can close out a put option it has  purchased by effecting a closing
sale  transaction;  for  example,  the Fund may  close  out a put  option it has
purchased  by selling a put option.  If,  however,  a secondary  market does not
exist at a time the Fund wishes to effect a closing sale  transaction,  the Fund
will have to  exercise  the option to realize  any  profit.  In  addition,  in a
transaction in which the Fund does not own the security  underlying a put option
it has  purchased,  the Fund would be  required,  in the  absence of a secondary
market, to purchase the underlying security before it could exercise the option.
In each such instance, the Fund would incur additional transaction costs.

    The Fund may also  purchase  call  options  for the  purpose  of  offsetting
previously written call options of the same series.

    The Fund will not  purchase a put  option if, as a result of such  purchase,
more  than 10% of its  total  assets  would be  invested  in  premiums  for such
options.  The Fund's  ability to purchase put and call options may be limited by
the  Internal  Revenue  Code's  requirements  for  qualification  as a regulated
investment company.

OPTION WRITING AND RELATED RISKS

    The Fund may write  covered  call and put  options.  A call option gives the
purchaser of the option the right to buy, and the writer the obligation to sell,
the  underlying  security  at the  exercise  price  during  the  option  period.
Conversely,  a put option gives the purchaser the right to sell,  and the writer
the obligation to buy, the underlying  security at the exercise price during the
option period.

    So long  as the  obligation  of the  writer  continues,  the  writer  may be
assigned an exercise  notice by the  broker-dealer  through  whom the option was
sold. The exercise notice would require the writer to deliver,  in the case of a
call, or take delivery of, in the case of a put, the underlying security against
payment of the exercise price. This obligation terminates upon expiration of the
option,  or at such  earlier  time as the  writer  effects  a  closing  purchase
transaction  by  purchasing  an option of the same series as the one  previously
sold.  Once an option has been  exercised,  the writer may not execute a closing
purchase  transaction.  For  options  traded on  national  securities  exchanges
(Exchanges),  to secure the obligation to deliver the underlying security in the
case of a call option, the writer of the option is required to deposit in escrow
the underlying security or other assets in accordance with the rules of the OCC,
an  institution  created to  interpose  itself  between  buyers  and  sellers of
options.  Technically, the OCC assumes the order side of every purchase and sale
transaction  on an  Exchange  and,  by doing  so,  gives  its  guarantee  to the
transaction. 

    The  principal  reason for writing  options on a securities  portfolio is to
attempt to realize, through the receipt of premiums, a greater return than would
be realized on the underlying  securities alone. In return for the premium,  the
covered call option writer has given up the  opportunity for profit from a price
increase in the  underlying  security  above the  exercise  price so long as the
option  remains  open,  but  retains  the risk of loss  should  the price of the
security decline.  Conversely, the put option writer gains a profit, in the form
of a premium,  so long as the price of the underlying security remains above the
exercise  price,  but assumes an obligation to purchase the underlying  security
from the buyer of the put option at the exercise price, even though the price of
the  security  may fall below the  exercise  price at any time during the option
period.  If an option  expires,  the writer realizes a gain in the amount of the
premium.  Such a gain may, in the case of a covered call option,  be offset by a
decline in the market value of the underlying security during the option period.
If a call option is exercised,  the writer realizes a gain or loss from the sale
of the  underlying  security.  If a put option is  exercised,  the  writer  must
fulfill his  obligation  to purchase  the  underlying  security at the  exercise
price,  which  will  usually  exceed  the then  market  value of the  underlying
security.  In addition,  the premium paid for the put effectively  increases the
cost of the underlying  security,  thus reducing the yield  otherwise  available
from such securities.

    Because the Fund can write only covered  options,  it may at times be unable
to write additional  options unless it sells a portion of its portfolio holdings
to obtain  new debt  securities  against  which it can write  options.  This may
result  in higher  portfolio  turnover  and  correspondingly  greater  brokerage
commissions and other transaction costs.

    To the extent  that a secondary  market is  available,  the  covered  option
writer  may close out  options  it has  written  prior to the  assignment  of an
exercise notice by purchasing,  in a closing purchase transaction,  an option of
the same series as the option previously  written. If the cost of such a closing
purchase,  plus  transaction  costs,  is greater than the premium  received upon
writing the original option, the writer will incur a loss on the transaction.

OPTIONS TRADING MARKETS

    Options  which  the  Fund  will  trade  are  generally  listed  on  national
securities  exchanges.  Exchanges on which such options currently are traded are
the Chicago  Board  Options  Exchange  and the New York,  American,  Pacific and
Philadelphia Stock Exchanges (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 would fail to meet their obligations
to the 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,  the Fund is
subject to the  investment  restrictions  described  in the  prospectus  and the
statement of additional information.

    The staff of the  Commission is of the view that the premiums which the Fund
pays for the purchase of unlisted  options,  and the value of securities used to
cover  unlisted  options  written by the Fund are  considered  to be invested in
illiquid securities or assets for the purpose of calculating whether the Fund is
in compliance with its fundamental  investment  restriction  prohibiting it from
investing  more than 10% of its total  assets  (taken at  current  value) in any
combination of illiquid assets and securities.  The Fund intends to request that
the  Commission  staff  reconsider  its view. It is the intention of the Fund to
comply   with  the   staff's   current   position   and  the   outcome  of  such
reconsideration.

SPECIAL CONSIDERATIONS APPLICABLE TO OPTIONS

    ON TREASURY BONDS AND NOTES. Because trading interest in U.S. Treasury bonds
and notes tends to center on the most recently  auctioned issues,  new series of
options with expirations to replace  expiring options on particular  issues will
not be  introduced  indefinitely.  Instead,  the  expirations  introduced at the
commencement  of options  trading on a  particular  issue will be allowed to run
their course,  with the possible addition of a limited number of new expirations
as the original  ones expire.  Options  trading on each series of bonds or notes
will thus be phased out as new options are listed on the more recent issues, and
a full range of  expiration  dates will not  ordinarily  be available  for every
series on which options are traded.

    ON TREASURY BILLS.  Because the deliverable U.S.  Treasury bill changes from
week to week,  writers of U.S.  Treasury  bill call  options  cannot  provide in
advance for their  potential  exercise  settlement  obligations by acquiring and
holding the underlying  security.  However, if the Fund holds a long position in
U.S. Treasury bills with a principal amount corresponding to the option contract
size, the Fund may be hedged from a risk standpoint.  In addition, the Fund will
maintain in a segregated  account with its Custodian  liquid assets  maturing no
later than those which would be  deliverable in the event of an assignment of an
exercise notice to ensure that it can meet its open option obligations.

    ON GNMA CERTIFICATES.  Options on GNMA certificates are not currently traded
on any  Exchange.  However,  the Fund may purchase and write such options in the
over-the-counter market, or should they commence trading, on any Exchange.

    Since the remaining  principal  balance of GNMA  certificates  declines each
month as a result of mortgage payments,  the Fund, as a writer of a covered GNMA
call holding GNMA certificates as "cover" to satisfy its delivery  obligation in
the  event  of  assignment  of an  exercise  notice,  may  find  that  its  GNMA
certificates no longer have a sufficient  remaining  principal  balance for this
purpose.  Should  this  occur,  the Fund  will  enter  into a  closing  purchase
transaction or will purchase additional GNMA certificates from the same pool (if
obtainable)  or  replacement  GNMA  certificates  in the cash market in order to
remain covered.

    A GNMA  certificate  held by the Fund to cover an option position in any but
the nearest  expiration  month may cease to present  cover for the option in the
event of a decline  in the GNMA  coupon  rate at which new pools are  originated
under the FHA/VA loan  ceiling in effect at any given  time.  Should this occur,
the Fund will no longer  be  covered,  and the Fund  will  either  enter  into a
closing purchase  transaction or replace the GNMA certificate with a certificate
which represents  cover.  When the Fund closes its position or replaces the GNMA
certificate, it may realize an unanticipated loss and incur transaction costs.

    RISKS PERTAINING TO THE SECONDARY  MARKET.  An option position may be closed
out only in a secondary  market for an option of the same  series.  Although the
Fund will generally purchase or 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 closing  transactions in particular options,  with the result that the
Fund would have to exercise its options in order to realize any profit and might
incur transaction costs in connection  therewith.  If the Fund as a covered call
option writer is unable to effect a closing purchase  transaction in a secondary
market,  it will not be able to sell the  underlying  security  until the option
expires or it delivers the underlying security upon exercise.

    Reasons for the absence of a liquid  secondary market include the following:
(i) insufficient trading interest in certain options;  (ii) restrictions imposed
on transactions;  (iii) trading halts, suspensions or other restrictions imposed
with  respect  to  particular   classes  or  series  of  options  or  underlying
securities;  (iv)  interruption of the normal  operations on an Exchange or by a
broker; (v) inadequacy of the facilities of an Exchange,  the OCC or a broker to
handle current trading volume;  or (vi) a decision by one or more Exchanges or a
broker to discontinue the trading of options (or a particular class or series of
options), in which event the secondary market in that class or series of options
would cease to exist,  although  outstanding  options  that had been issued as a
result of trades would  generally  continue to be exercisable in accordance with
their terms.

    The hours of trading  for  options  on U.S.  government  securities  may not
conform to the hours during which the underlying  securities are traded.  To the
extent that the option  markets  close  before the  markets  for the  underlying
securities,  significant  price  and  rate  movements  can  take  place  in  the
underlying markets that cannot be reflected in the option markets.

               FUTURES CONTRACTS AND RELATED OPTIONS TRANSACTIONS

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

    For example, when the 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 the 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,  the 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 Fund  intends to engage in  options  transactions  which are  related to
currency  and other  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 Fund's  exposure  to
interest  rate  and/or  market  fluctuations,  the Fund may be able to hedge its
exposure  more  effectively  and perhaps at a lower cost through  using  futures
contracts and related  options  transactions.  While the Fund does not intend to
take delivery of the instruments underlying futures contracts it holds, the Fund
does not intend to enter into 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  currencies,   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 the
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 the 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

STOCK INDEX FUTURES CONTRACTS

    A stock index assigns  relative  values to the common stocks included in the
index.  The index  fluctuates  with  changes in the market  values of the common
stocks so included.  A stock index futures contract is a bilateral  agreement by
which two parties agree to take or make delivery of an amount of cash equal to a
specified  dollar amount times the  difference  between the closing value of the
stock index on the  expiration  date of the  contract and the price at which the
futures  contract is  originally  made. No physical  delivery of the  underlying
stocks in the index is made.

    Currently, stock index futures contracts can be purchased or sold on the S&P
Index of 500 Stocks,  the S&P Index of 100 Stocks,  the New York Stock  Exchange
Composite Index, the Value Line Index and the Major Market Index. It is expected
that futures  contracts  trading in additional stock indices will be authorized.
The standard contract size is $500 times the value of the index.

    The Fund does not believe that  differences  between  existing stock indices
will create any  differences  in the price  movements of the stock index futures
contracts  in  relation  to  the  movements  in  such  indices.   However,  such
differences  in the  indices may result in  differences  in  correlation  of the
futures with movements in the value of the securities being hedged.

OTHER INDEX BASED FUTURES CONTRACTS

    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 Fund will sell interest rate index and
other index based futures  contracts to hedge against changes which are expected
to affect the Fund's portfolio.

    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 the 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 the 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 the
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 the 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,   the  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 its initial  margin 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 the 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 the 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 the Fund.

    There can be no assurance, however, that the Fund will be able to enter into
an offsetting  transaction with respect to a particular contract at a particular
time. If the 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 CURRENCY AND OTHER FINANCIAL FUTURES

    The Fund  intends to  purchase  call and put  options on  currency  or other
financial  futures  contracts  and sell such  options to  terminate  an existing
position.  Options on currency or other financial futures are similar to options
on stocks  except  that an  option  on a  currency  or other  financial  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
currency  or  other  instruments  making  up a  financial  futures  index,  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 Fund  intends to use options on  currency  and other  financial  futures
contracts in connection with hedging strategies.  In the future the Fund may use
such options for other purposes.

PURCHASE OF PUT OPTIONS ON FUTURES CONTRACTS

    The  purchase of  protective  put  options on  currency  or other  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 the 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 a call  option on a currency  or other  financial  futures
contract   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
the Fund is not fully invested.

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

    The Fund may employ new investment  techniques  involving currency and other
financial  futures  contracts  and  related  options.  The Fund  intends 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 Fund in the foreseeable future other than those described above.

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

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

    The 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 the Fund owns, or futures contracts will be purchased to protect
the Fund against an increase in the price of  securities it intends to purchase.
The Fund does not intend to enter into futures contracts for speculation.

    In instances  involving  the purchase of futures  contracts by the 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, the 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 the  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 the  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,  the 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

    Currency and other 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 the 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,  the 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 the 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 currency and other  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.  The 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 the 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 the 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.

                         FOREIGN CURRENCY TRANSACTIONS

    The Fund may invest in securities of foreign issuers.  When the 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 a
Fund share will be affected by changes in exchange rates.


FORWARD CURRENCY CONTRACTS

    As one way of managing  exchange  rate risk,  the Fund may engage in forward
currency  exchange  contracts  (agreements  to purchase or sell  currencies at a
specified  price  and  date).  Under the  contract,  the  exchange  rate for the
transaction  (the amount of currency  the Fund will  deliver or receive when the
contract is completed) is fixed when the Fund enters into the contract. The Fund
usually will enter into these  contracts to stabilize the U.S. dollar value of a
security it has agreed to buy or sell. The Fund also may use these  contracts to
hedge the U.S.  dollar value of a security it already owns,  particularly if the
Fund  expects a  decrease  in the  value of the  currency  in which the  foreign
security is  denominated.  Although  the 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 the Fund's investments  denominated
in foreign  currencies will depend on the relative  strength of those currencies
and the U.S.  dollar,  and the Fund may be affected  favorably or unfavorably by
changes in the exchange rate 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 the Fund.

CURRENCY FUTURES CONTRACTS

    Currency futures contracts are bilateral  agreements under which two parties
agree  to take  or make  delivery  of a  specified  amount  of a  currency  at a
specified  future  time for a  specified  price.  Trading  of  currency  futures
contracts in the United States is regulated under the Commodity  Exchange Act by
the Commodity Futures Trading Commission (CFTC) and National Futures Association
(NFA).  Currently the only national  futures  exchange on which currency futures
are  traded  is the  International  Monetary  Market of the  Chicago  Mercantile
Exchange.  Foreign  currency futures trading is conducted in the same manner and
subject to the same  regulations  as trading in  interest  rate and index  based
futures.  The Fund  intends to only engage in  currency  futures  contracts  for
hedging  purposes,  and not for  speculation.  The Fund may  engage in  currency
futures  contracts for other  purposes if authorized to do so by the Board.  The
hedging  strategies  which will be used by the Fund in  connection  with foreign
currency  futures  contracts  are similar to those  described  above for forward
foreign currency exchange contracts.

    Currently,  currency  futures  contracts  for the  British  Pound  Sterling,
Canadian Dollar, Dutch Guilder, Deutsche Mark, Japanese Yen, Mexican Peso, Swiss
Franc,  and French Franc can be purchased or sold for U.S.  dollars  through the
International  Monetary Market. It is expected that futures contracts trading in
additional  currencies  will be  authorized.  The  standard  contract  sizes are
L125,000  for the Pound,  125,000  for the  Guilder,  Mark and Swiss  Francs and
French Francs,  C$100,000 for the Canadian Dollar,  Y12,500,000 for the Yen, and
1,000,000 for the Peso. In contrast to Forward Currency Exchange Contracts which
can be traded at any time,  only four value  dates per year are  available,  the
third Wednesday of March, June, September and December.

FOREIGN CURRENCY OPTIONS TRANSACTIONS

    Foreign  currency  options (as opposed to futures) are traded ina variety of
currencies  in both the United  States and  Europe.  On the  Philadelphia  Stock
Exchange, for example,  contracts for half the size of the corresponding futures
contracts  on the  Chicago  Board  Options  Exchange  are traded with up to nine
months  maturity  in Marks,  Sterling,  Yen,  Swiss  Francs,  French  Francs and
Canadian Dollars. Options can be exercised at any time during the contract life,
and require a deposit  subject to normal  margin  requirements.  Since a futures
contract  must be  exercised,  the  Fund  must  continually  make up the  margin
balance.  As a result,  a wrong price move could  result in the Fund losing more
than the original  investment,  as it cannot walk away from the futures contract
as it can an option contract.

    The Fund  will  purchase  call and put  options  and sell  such  options  to
terminate  an  existing  position.  Options on foreign  currency  are similar to
options on stocks  except that an option on an interest  rate and/or index based
future  contract gives the purchaser the right,  in return for the premium paid,
to purchase or sell foreign currency,  rather than to purchase or sell stock, at
a specified exercise price at any time during the period of the option.

    The Fund intends to use foreign  currency option  transactions in connection
with hedging strategies.

PURCHASE OF PUT OPTIONS ON FOREIGN CURRENCIES

    The purchase of protective put options on a foreign currency 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 the Fund. Put options may be purchased to hedge a portfolio of foreign stocks
or foreign debt instruments or a position in the foreign currency upon which the
put option is based.


PURCHASE OF CALL OPTIONS ON FOREIGN CURRENCIES

    The purchase  of a call  option on foreign  currency  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 foreign  currency upon which it is
based,  or upon the price of the  foreign  stock or  foreign  debt  instruments,
purchase  of a call option may be less risky than the  ownership  of the foreign
currency or the foreign  securities.  The Fund would purchase a call option on a
foreign  currency to hedge  against an  increase  in the  foreign  currency or a
foreign market advance when the Fund is not fully invested.

    The Fund may employ new  investment  techniques  involving  forward  foreign
currency exchange  contracts,  foreign currency futures contracts and options on
foreign  currencies in order 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 Fund in the foreseeable  future other
than those described above.

CURRENCY TRADING RISKS

    Currency  exchange  trading may involve  significant  risks.  The four major
types of risk the Fund faces are exchange rate risk,  interest rate risk, credit
risk and country risk.

EXCHANGE RATE RISK

    Exchange rate risk results from the movement up and down of foreign currency
values in response to shifting  market supply and demand.  When the Fund buys or
sells a foreign currency, an exposure called an open position is created.  Until
the time that  position  can be  "covered"  by selling  or buying an  equivalent
amount of the same  currency,  the Fund is exposed to the risk that the exchange
rate might move against it. Since  exchange rate changes can readily move in one
direction,  a  position  carried  overnight  or over a number  of days  involves
greater risk than one carried a few minutes or hours. Techniques such as foreign
currency  forward and futures  contracts  and  options on foreign  currency  are
intended to be used by the Fund to reduce exchange rate risk.


MATURITY GAPS AND INTEREST RATE RISK

    Interest  rate risk  arises  whenever  there are  mismatches  or gaps in the
maturity  structure of the Fund's foreign exchange currency  holdings,  which is
the total of its outstanding spot and forward or futures contracts.

    Foreign currency transactions often involve borrowing short term and lending
longer term to benefit from the normal  tendency of interest  rates to be higher
for longer maturities.  However in foreign exchange trading,  while the maturity
pattern of interest rates for one currency is important,  it is the differential
between interest rates for two currencies that is decisive.


CREDIT RISK

    Whenever the Fund enters into a foreign exchange contract,  it faces a risk,
however small, that the counterparty  will not perform under the contract.  As a
result there is a credit risk, although no extension of "credit" is intended. To
limit credit risk,  the Fund  intends to evaluate the  creditworthiness  of each
other  party.  The Fund does not  intend to trade more than 5% of its net assets
under foreign exchange contracts with one party.

    Credit  risk  exists  because  the  Fund's  counterparty  may be  unable  or
unwilling to fulfill its  contractual  obligations  as a result of bankruptcy or
insolvency or when foreign exchange controls  prohibit  payment.  In any foreign
exchange transaction,  each party agrees to deliver a certain amount of currency
to the other on a particular  date. In establishing  its hedges a Fund relies on
each contract being completed. If the contract is not performed, then the Fund's
hedge is  eliminated,  and the Fund is exposed to any changes in exchange  rates
since the contract was  originated.  To put itself in the same position it would
have  been in had the  contract  been  performed,  the Fund  must  arrange a new
transaction.  However, the new transaction may have to be arranged at an adverse
exchange  rate.  The trustee for a bankrupt  company may elect to perform  those
contracts  which are  advantageous  to the company but disclaim those  contracts
which are disadvantageous, resulting in losses to the Fund.

    Another form of credit risk stems from the time zone differences between the
U.S.  and foreign  nations.  If the Fund sells  sterling it  generally  must pay
pounds  to a  counterparty  earlier  in the day  than it will be  credited  with
dollars in New York. In the intervening  hours, the buyer can go into bankruptcy
or can be  declared  insolvent.  Thus,  the dollars may never be credited to the
Fund.

COUNTRY RISK

    At one  time  or  another,  virtually  every  country  has  interfered  with
international  transactions in its currency.  Interference has taken the form of
regulation of the local exchange market,  restrictions on foreign  investment by
residents,  or limits on inflows of  investment  funds from abroad.  Governments
take such measures,  for example,  to improve control over the domestic  banking
system,  or to influence the pattern of receipts and payments between  residents
and  foreigners.  In those  cases,  restrictions  on the  exchange  market or on
international  transactions  are intended to affect the level or movement of the
exchange rate.  Occasionally  a serious  foreign  exchange  shortage may lead to
payments  interruptions or debt servicing delays, as well as interference in the
exchange market.  It has become  increasingly  difficult to distinguish  foreign
exchange or credit risk from country risk.

    Changes in regulations or restrictions usually do have an important exchange
market impact.  Most  disruptive  are changes in rules which  interfere with the
normal payments mechanism.  If government  regulations change and a counterparty
is either  forbidden to perform or is required to do something  extra,  then the
Fund might be left with an unintended  open  position or an unintended  maturity
mismatch.  Dealing with such  unintended long or short positions could result in
unanticipated costs to the Fund.

    Other changes in official  regulations  influence  international  investment
transactions.  If one of the  factors  affecting  the  buying  or  selling  of a
currency  changes,  the  exchange  rate is likely to  respond.  Changes  in such
controls  often are  unpredictable  and can create a  significant  exchange rate
response.

    Many major  countries  have moved  toward  liberalization  of  exchange  and
payments   restrictions   in  recent  years  or  accepted  the  principle   that
restrictions  should be relaxed.  A few  industrial  countries have moved in the
other direction.  Important liberalizations were carried out by Switzerland, the
United Kingdom and Japan.  They  dismantled  mechanisms for  restricting  either
foreign exchange inflows (Switzerland),  outflows (Britain), or elements of both
(Japan).  By  contrast,  France  and  Mexico  have  tightened  foreign  exchange
controls.

    Overall,  many  exchange  markets  are  still  heavily  restricted.  Several
countries limit access to the forward market to companies  financing  documented
export or import  transactions  in an effort to insulate  the market from purely
speculative  activities.  Some of these countries  permit local traders to enter
into forward contracts with residents but prohibit certain forward  transactions
with  nonresidents.  By  comparison,  other  countries  have strict  controls on
exchange  transactions  by  residents,  but permit  free  exchange  transactions
between local traders and non-residents. A few countries have established tiered
markets,  funneling  commercial  transactions  through one market and  financial
transactions through another. Outside the major industrial countries, relatively
free  foreign  exchange  markets  are  rare and  controls  on  foreign  currency
transactions are extensive.

    Another aspect of country risk has to do with the possibility  that the Fund
may be dealing  with a foreign  trader  whose home  country is facing a payments
problem.  Even  though the  foreign  trader  intends  to perform on its  foreign
exchange  contracts,  the contracts are tied to other external  liabilities  the
country has incurred. As a result,  performance may be delayed and can result in
unanticipated  cost to the Fund.  This aspect of country risk is a major element
in the Fund's credit judgment as to with whom it will deal and in what amounts.

    CLOSING  SALE  TRANSACTION.  A  transaction  in which an investor who is the
holder or buyer of an  outstanding  option or futures  contract  liquidates  his
position  as a holder or a buyer by selling an option of the same  series as the

contract  previously  purchased.  (Such  sale does not  result  in the  investor
assuming the obligations of a writer or seller.)

    COVERED  CALL  OPTION  WRITER.  A writer of a call option who, so long as he
remains  obligated as a writer,  owns the shares of the  underlying  security or
holds on a share for share basis a call on the same security  where the exercise
price of the call held is equal to or less than the  exercise  price of the call
written,  or,  if  greater  than the  exercise  price of the call  written,  the

(b) Figures are net of expense reimbursement by Keystone in connection with 
    voluntary expense limitations. Before the expense reimbursement, the 
    "Ratio of net operating and management expenses to average net assets" 
    would have been 2.37% and 2.61% for the year ended July 31, 1994 and the 
    period February 1, 1993 (Date of Initial Public Offering) to July 31, 
    1993. 
(c) Effective August 1, 1993, the Fund adopted Statement of Position 93-2: 
    "Determination, Disclosure and Financial Statement Presentation of 
    Income, Capital Gain and Return of Capital Distributions by Investment 
    Companies." As a result, distribution amounts exceeding book basis net 
    investment income (or tax basis net income on a temporary basis) are 
    presented as "Distributions in excess of investment income--net." 
    Similarly, capital gain distributions in excess of book basis capital 
    gains (or tax basis capital gains on a temporary basis) are presented as 
    "Distributions in excess of net realized capital gains." 
(d) Excluding sales charges. 
(e) Calculation based on average shares outstanding.

Keystone America Intermediate Term Bond Fund 
NOTES TO FINANCIAL STATEMENTS 

(1.) Significant Accounting Policies 

Keystone America Intermediate Term Bond Fund (the "Fund") is a Massachusetts 
business trust for which Keystone Management, Inc. ("KMI") is the Investment 
Manager and Keystone Custodian Funds, Inc. ("Keystone") is the Investment 
Adviser. The Fund was organized on October 24, 1986 and had no operations 
prior to February 13, 1987. It is registered under the Investment Company Act 
of 1940 as a diversified open-end investment company, issuing three classes 
of shares, specifically Class A, Class B, and Class C shares. 

Class A shares are sold subject to a maximum sales charge of 4.75% payable at 
the time of purchase. Class B shares are sold subject to a contingent 
deferred sales charge payable upon redemption within three calendar years 
after the year of purchase. Class C shares are sold subject to a contingent 
deferred sales charge payable upon redemption within one year of purchase. 
Class C shares are available only through dealers who have entered into 
special distribution agreements with Keystone 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 of Keystone and its affiliates. 
KMI is a wholly-owned subsidiary of Keystone. Keystone Investor Resource 
Center, Inc. ("KIRC") a wholly-owned subsidiary of Keystone, is the Fund's 
transfer agent. 

The following is a summary of significant accounting policies consistently 
followed by the Fund in the preparation of its financial statements. The 
policies are in conformity with generally accepted accounting 
principles. 

A. Investments are usually valued at the closing sales price, or in the 
absence of sales and for over-the-counter securities, the mean of bid and 
asked quotations. Management values the following securities at prices it 
deems in good faith to be fair: (i) securities (including restricted 
securities) for which complete quotations are not readily available and (ii) 
listed securities if, in the opinion of management, the last sales price does 
not reflect a current value, or if no sale occurred. 

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. Short- term investments denominated in 
a foreign currency are adjusted daily to reflect changes in exchange rates. 
Market quotations are not considered to be readily available for long-term 
corporate bonds and notes; such investments are stated at fair value on the 
basis of valuations furnished by a pricing service, approved by the Trustees, 
which determines valuations for normal, institutional-size trading units of 
such securities using methods based on market transactions for comparable 
securities and various relationships between securities that are generally 
recognized by institutional traders. 

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 
<PAGE>
 
into a futures contract the Fund is required to deposit with a broker an 
amount ("initial margin") equal to a certain percentage of the purchase price 
indicated in the futures contract. Subsequent payments ("variation margin") 
are made or received by the Fund each day, as the value of the underlying 
instrument or index fluctuates, and are recorded for book purposes as 
unrealized gains or losses by the Fund. For federal tax purposes, any futures 
contracts which remain open at fiscal year end are marked-to-market and the 
resultant net gain or loss is included in federal taxable income. 

B. Securities transactions are accounted for on the trade date. Interest 
income is recorded on the accrual basis and dividend income is recorded on 
the ex-dividend date. Distributions to the shareholders are recorded by the 
Fund at the close of business on the record date. 

C. The 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, the Fund is relieved of any federal 
income or excise tax liability by distributing all of its net taxable net 
investment income and net taxable capital gains, if any, to its shareholders. 
The Fund intends to avoid excise tax liability by making the required 
distributions under the Internal Revenue Code. 

D. For the year ended July 31, 1993, the Fund used the accounting practice 
known as equalization by which a portion of the proceeds from sales and the 
costs of redemptions of capital shares (equivalent on a per share basis to 
the amount of undistributed net investment income on the date of the 
transactions) was credited or charged to undistributed income. As a result, 
undistributed net investment income per share was not affected by sales or 
redemptions of shares. Effective August 1, 1993 the Fund discontinued 
equalization accounting. 

E. When the 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. The Fund monitors the value of 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, the 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 the 
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 the 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. From time to time the Fund may enter into forward foreign currency 
exchange contracts to hedge certain foreign currency assets. Contracts are 
recorded at market value. Realized gains and losses arising from such 
transactions are included in realized gain (loss) on foreign currency related 
transactions. The Fund is subject to the credit risk that the other party 
will not complete the obligations of the contract.

G. The Fund distributes net investment income monthly, and net capital gains, 
if any, annually. 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. Excess distributions were previously charged to 
paid-in-capital. Effective August 1, 1993, the Fund adopted Statement of 
Position 93-2: Determination, Disclosure, and Financial Statement 
Presentation of Income, Capital Gain and Return of Capital Distributions by 
Investment Companies (the "Statement"). As a result of this statement, the 
Fund changed the financial statement classification of distributions to 
shareholders to more clearly reflect the differences between financial 
statement amounts available for distributions and amounts distributed to 
comply with income tax regulations. Accordingly, amounts as of July 31, 1993 
have been restated to reflect a decrease to undistributed investment 
income--net and accumulated realized gains (losses) of $97,683 and $58,515, 
respectively, and a corresponding increase to paid-in capital of $156,198. 

(2.) Capital Share Transactions 

The Trust Agreement authorizes the issuance of an unlimited number of shares 
of beneficial interest without par value. 

Transactions in shares of the Fund were as follows:

The 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 Investment Company Act of 1940 ("1940 Act"). 

The Class A Distribution Plan provides for payments which are currently 
limited to 0.25% 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 
the 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 0.25% of the 
average net asset value of the 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 
1.00% of the average daily net asset value of Class B shares to pay expenses 
of the distribution of Class B shares. Amounts paid by the 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 
0.25% of the average net asset value of shares sold by such others and 
remaining outstanding on the books of the Fund for specified periods. 

The Class C Distribution Plan provides for payments at an annual rate of 1.00%
of the average daily net asset value of Class C shares to pay expenses of the
distribution of Class C shares. Amounts paid by the Fund under the Class C
Distribution Plan are currently used to pay others (dealers) (i) a commission at
the time of purchase normally equal to 1.00% of the value of each share sold;
and (ii) a commission at an annual rate of 0.75% (subject to applicable
limitations imposed by the rules of the National Association of Securities
Dealers, Inc.) and service fees at an annual rate of 0.25% of the average net
asset value of each share sold by such others and remaining outstanding on the
books for specified periods, beginning approximately 15 months after purchase.
Unreimbursed distribution expenses at July 31, 1994 for Class C shares were
$995,039.

Each of the Distribution Plans may be terminated at any time by a vote of the 
Independent Trustees or by a vote of a majority of the outstanding voting 
shares of the respective class. However, after termination of the Class B 
Distribution Plan, payments to KDI will continue at the annual rate of 1.00% 
of the average daily net asset value of Class B shares, as compensation for 
its services which had been earned while the Class B Distribution Plan was in 
effect. Such unreimbursed distribution expenses for the year ended July 31, 
1994 for Class B shares were $1,086,574. 

During the year ended July 31, 1994, the Fund paid or accrued to KDI $43,683, 
$152,644, and $123,555 for Class A, Class B, and Class C Distribution Plans, 
respectively. 

(3.) Securities Transactions 

Realized gains and losses are computed on the identified cost basis. As of 
July 31, 1994, the Fund had a capital loss carryover for federal income tax 
purposes of approximately $970,000 which expires in 1999. Purchases and sales 
of investment securities (including proceeds received at maturity) for the 
year ended July 31, 1994 were as follows:

(4.) Investment Management and Transactions with Affiliates 

Under the terms of the Investment Management Agreement between KMI and the 
Fund, dated December 29, 1989, KMI provides investment management and 
administrative services to the Fund. In return, KMI is paid a management fee 
computed and paid daily calculated at a rate of 2.0% of the Fund's gross 
investment income plus an amount determined by applying percentage rates, 
which start at 0.50% and decline, as net assets increase, to 0.25% per annum, 
to the net asset value of the Fund. KMI has entered into an Investment 
Advisory Agreement with Keystone, dated December 30, 1989 under which 
Keystone provides investment advisory and management services to the Fund and 
receives for its services an annual fee representing 85% of the management 
fee received by KMI. During the year ended July 31, 1994, the Fund paid or 
accrued to KMI investment management and administrative service fees of 
$290,111, which represented 0.60% of the Fund's average net assets on an 
annualized basis. Of such amount paid to KMI, $246,594 was paid to Keystone 
for its services to the Fund. 

During the year ended July 31, 1994, the Fund paid or accrued to KIRC $18,880 
as reimbursement for certain accounting and printing services provided to the 
Fund. 

During the year ended July 31, 1994, $130,879 was paid or accrued to KIRC for 
shareholder services. 

The Fund is subject to certain state annual expense limits, the most 
restrictive of which is as follows: 2.5% of the first $30 million of Fund 
assets, 2.0% of the next $70 million of Fund assets, and 1.5% of Fund assets 
over $100 million. 

Beginning January 1, 1993, Keystone has voluntarily agreed to reimburse all 
expenses, including the management fee, incurred by the Fund in excess of 
1.0% on Class A shares, and 1.75% on Class B and Class C shares beginning 
February 1, 1993. Keystone would not be required to make such reimbursement 
to an extent which would result in the Fund's inability to qualify as a 
regulated investment company under the provisions of the Internal Revenue 
Code. In accordance with these voluntary expense limitations, Keystone 
reimbursed the Fund during the year ended July 31, 1994, $129,577, $92,657, 
and $76,307 for Class A, Class B, and Class C shares, respectively. Keystone 
does not intend to seek repayment of these amounts. 

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 
receive no compensation for their services. 

(5.) Class Level Expenses 

Presently, the Fund's class-specific expenses are limited to expenses 
incurred by a class of shares pursuant to its respective Distribution Plan. 
For the year ended July 31, 1994, the total amount of expenses incurred by 
each class's Distribution Plan is set forth in Note (2). "Capital Share 
Transactions." 

(6.) Distribution to Shareholders 

Distributions of $0.05 per share for Class A, $0.044 for Class B, and $0.044 
for Class C from net investment income was declared payable by September 7, 
1994 to shareholders of record August 25, 1994. This distribution is not 
reflected in the accompanying financial statements. 

The Fund intends to distribute to its shareholders dividends from net 
investment income monthly and all net taxable realized long-term capital 
gains, if any, annually. Any distribution which is declared in December and 
paid before the next February 1 will be taxable to shareholders in the year 
declared.

The Trustees and Shareholders 
Keystone America Intermediate Term Bond Fund

each of the years in the seven-year period ended July 31, 1994, and the 
period from February 13, 1987 (Commencement of Operations) to July 31, 1987 
for Class A shares and for the year ended July 31, 1994 and for the period 
from February 1, 1993 to July 31, 1993 for Class B and Class C shares. These 
financial statements and financial highlights are the responsibility of the 
Fund's management. Our responsibility is to express an opinion on these 
financial statements and financial highlights based on our audits. 

We conducted our audits in accordance with generally accepted auditing

obtain reasonable assurance about whether the financial statements and 
financial highlights are free of material misstatement. An audit includes 
examining, on a test basis, evidence supporting the amounts and disclosures 
in the financial statements. Our procedures included confirmation of 
securities owned as of July 31, 1994, by correspondence with the custodian 
and brokers. An audit also includes assessing the accounting principles used 
and significant estimates made by management, as well as evaluating the 
overall financial statement presentation. We believe that our audits provide 
a reasonable basis for our opinion.

above present fairly, in all material respects, the financial position of 
Keystone America Intermediate Term Bond Fund as of July 31, 1994, the results 
of its operations for the year then ended, the changes in its net assets for
