  Keystone  Tax Free Fund (the  "Fund") is a mutual  fund that seeks the highest
possible  current  income,  exempt from federal income taxes,  while  preserving
capital.  The Fund invests  primarily in municipal  bonds.  The Fund's net asset
value per share will fluctuate in response to changes in the market value of its
portfolio securities.

   
  Except  as noted  below,  the Fund  generally  offers  its  shares  by  direct
investment only to  shareholders  who  beneficially  own shares of the Fund. The
Fund also offers its shares through  exchanges to  shareholders of certain other
funds in the Keystone Investments Family of Mutual Funds. Beginning May 1, 1995,
the Fund will be reopen to new investors. It is presently intended that the Fund
remain  open  until  July 31,  1995 or until  the Fund  attains  $50,000,000  in
aggregate sales, whichever occurs first (the "Special Offering Period").
    

  Your purchase payment is fully invested. There is no sales charge when you buy
the Fund's shares.  The Fund may impose a deferred sales charge,  which declines
from 4% to 1%, if you redeem your shares within four years of purchase.

  The Fund has adopted a Distribution Plan (the "Distribution Plan") pursuant to
Rule 12b-1 under the Investment Company Act of 1940 (the "1940 Act") under which
it bears some of the costs of selling its shares to the public.

  This prospectus  sets forth concisely the information  about the Fund that you
should know before investing. Please read it and retain it for future reference.

   
  Additional  information  about  the  Fund  is  contained  in  a  statement  of
additional  information  dated  April 28,  1995,  which has been  filed with the
Securities and Exchange  Commission and is  incorporated  by reference into this
prospectus.  For a free copy, or for other  information about the Fund, write to
the address or call the telephone number listed above.
    

  SHARES  OF THE FUND ARE NOT  DEPOSITS  OR  OBLIGATIONS  OF, OR  GUARANTEED  OR
ENDORSED  BY,  ANY BANK,  AND SHARES ARE NOT  FEDERALLY  INSURED BY THE  FEDERAL
DEPOSIT INSURANCE CORPORATION, THE FEDERAL RESERVE BOARD, OR ANY OTHER AGENCY.

(1) The deferred sales charge declines from 4% to 1% of amounts  redeemed within
    four  calendar  years after  purchase.  No deferred  sales charge is imposed
    thereafter.
(2) There is no exchange  fee for exchange  orders  received by the Fund from an
    individual  shareholder over the Keystone  Automated Response Line ("KARL").
    (For a description of KARL, see "Shareholder Services.")
(3) To reflect current fees,  expense ratios are estimated for the Fund's fiscal
    year ending December 31, 1995. The estimated  expense ratios reflect certain
    actions  taken by the  Fund's  Board of  Trustees,  in  connection  with the
    reopening  of the Fund on May 1, 1995,  with  respect to the maximum  annual
    expenditures permitted under the Fund's Distribution Plan.
(4) Long-term  shareholders  may pay more than the  economic  equivalent  of the
    maximum  front end sales charge  permitted by rules  adopted by the National
    Association of Securities Dealers, Inc. ("NASD").
(5) 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%.

                        NOTES TO FINANCIAL HIGHLIGHTS

(a) Effective  January 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  investment
    income--net (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 gains (or tax basis capital gains on a
    temporary  basis) are  presented  as  "Distributions  in excess of  realized
    capital gains." For the fiscal years ended December 31, 1992, 1991 and 1990,
    distributions  in  excess  of  book  basis  net  income  were  presented  as
    "distribution from paid-in capital."
(b) Prior to June 30, 1987,  net  commissions  paid on new sales of shares under
    the Fund's Rule 12b-1  Distribution Plan had been treated for both financial
    statement  and tax  purposes  as  capital  charges.  On June 11,  1987,  the
    Securities  and  Exchange  Commission  adopted  a  rule  that  required  for
    financial  statements for the periods ended on or after June 30, 1987,  that
    net  commissions  paid under Rule  12b-1 be  treated as  operating  expenses
    rather than  capital  charges.  Accordingly,  beginning  with the year ended
    December  31,  1987,   the  Fund's   financial   statements   reflect  12b-1
    Distribution Plan expenses (i.e.,  shareholder service fees plus commissions
    paid net of deferred  sales charges  received by the Fund) as a component of
    net investment income.
(c) Excluding contingent deferred sales charges.

FUND DESCRIPTION
- ------------------------------------------------------------------------------

  The Fund is an open-end, diversified,  management investment company, commonly
known as a mutual fund. The Fund has been operating continuously since April 12,
1977 when it was created under  Massachusetts  law as a  Massachusetts  business
trust.  The Fund is one of twenty  funds  managed by Keystone  Management,  Inc.
("Keystone   Management"),   the  Fund's  investment  manager,  and  is  one  of
twenty-nine funds managed or advised by Keystone  Investment  Management Company
("Keystone"),  the Fund's investment  adviser.  Keystone and Keystone Management
are from time to time also collectively referred to as "Keystone."
    
- ------------------------------------------------------------------------------
FUND OBJECTIVE AND POLICIES
- ------------------------------------------------------------------------------

  The Fund's  investment  objective is to provide  shareholders with the highest
possible  current  income,  exempt from federal income taxes,  while  preserving
capital. The Fund invests  substantially all and, under ordinary  circumstances,
at least  80% of its  assets  in  federally  tax-exempt  obligations,  including
municipal bonds and notes and tax-exempt  commercial  paper  (municipal  bonds),
which  are  obligations  issued  by or on  behalf  of  states,  territories  and
possessions  of the United  States  ("U.S.),  the District of Columbia and their
political subdivisions, agencies and instrumentalities,  the interest from which
is, in the opinion of counsel to the issuers of such bonds,  exempt from federal
income taxes,  including the  alternative  minimum tax.  Municipal bonds include
debt obligations  issued by or on behalf of a political  subdivision of the U.S.
or any agency or  instrumentality  thereof to obtain  funds for  various  public
purposes.  In addition,  municipal  bonds  include  certain  types of industrial
revenue bonds issued by or on behalf of public  authorities to finance privately
operated  facilities.  General  obligation bonds involve the credit of an issuer
possessing  taxing power and are payable from the issuer's general  unrestricted
revenues.  Their payment may be dependent upon an  appropriation by the issuer's
legislative body and may be subject to quantitative  limitations on the issuer's
taxing  power.  Limited  obligation  or revenue  bonds are payable only from the
revenues of a particular facility or class of facilities or, in some cases, from
the proceeds of a special excise or other specific  revenue source,  such as the
user of the facility.  Since the Fund considers  preservation of capital as well
as the level of tax exempt income,  the Fund may realize less income than a fund
willing to expose shareholders" capital to greater risk.

   
  The Fund invests in municipal  bonds only if, at the date of investment,  they
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) or by Fitch Investors  Service,  Inc. -- Municipal Division
("Fitch")  (AAA, AA, A and BBB) or, if not rated,  are of comparable  quality to
obligations  so rated as determined by Keystone.  Bonds rated Baa by Moody's are
considered  to be  medium  grade  obligations,  i.e.,  they are  neither  highly
protected nor poorly secured.  Interest  payments and principal  security appear
adequate for the present,  but certain protective elements may be lacking or may
be characteristically  unreliable over any great length of time. Such bonds lack
outstanding investment  characteristics and have speculative  characteristics as
well.  Debt rated BBB by S&P is regarded  as having an adequate  capacity to pay
interest and repay principal.  While it normally  exhibits  adequate  protection
parameters,  adverse economic conditions or changing circumstances are generally
more likely to lead to a weakened  capacity to pay interest and repay  principal
for debt in this  category  than in high rated  categories.  Bonds  rated BBB by
Fitch are considered to be investment grade and of satisfactory  credit quality.
The obligator's  ability to pay interest and repay principal is considered to be
adequate. Adverse changes in economic conditions and circumstances, however, are
more likely to have adverse impact on these bonds,  and therefore  impair timely
payment.  The  likelihood  that the  ratings  of these  bonds  will  fall  below
investment grade is higher than for bonds with higher ratings.  Keystone expects
that under normal circumstances at least 65% of the Fund's total assets invested
in municipal bonds will be within the three highest ratings of such services or,
if not rated, will be of comparable quality.

  The Tax Reform Act of 1986 made significant  changes in the federal tax status
of certain  obligations  that previously were fully federally  tax-exempt.  As a
result,  three  categories of such  obligations  issued after August 7, 1986 now
exist:  (1) "public  purpose" bonds,  the income from which remains fully exempt
from  federal  income  taxes;  (2)  qualified  "private   activity"   industrial
development bonds, the income from which, while exempt from federal income taxes
under Section 103 of the Internal  Revenue Code ("the  Code"),  is includable in
the  calculation  of the  federal  alternative  minimum  tax;  and (3)  "private
activity"  (private  purpose)  bonds,  the income  from which is not exempt from
federal income taxes.  Investments in qualified  "private  activity"  industrial
development bonds will be limited by the Fund's policy of investing no more than
20% of its total assets in securities  that pay interest that is not exempt from
federal  taxation.  The Fund  currently  will not invest in  "private  activity"
(private purpose) bonds.
    

  The Fund also may invest in  securities  that pay interest  that is not exempt
from federal income taxes, such as corporate and bank  obligations,  obligations
issued  or  guaranteed  by the  U.S.  government  or by any of its  agencies  or
instrumentalities,  commercial paper and repurchase agreements.  Such securities
must be rated at least BBB by S&P or Baa by Moody's  or, if not  rated,  must be
determined  by  Keystone  to be  of  comparable  quality.  However,  except  for
temporary  defensive  purposes,  the Fund will not  invest  more than 20% of its
total assets in such securities.

   
  The Fund also may enter into reverse repurchase agreements and firm commitment
agreements  for  securities  and  currencies.  The Fund may enter  into  options
transactions  and may write covered call and put options,  purchase call and put
options,  including  purchasing  call  and put  options  to close  out  existing
positions,  and purchase call options to fix the interest  rates of  obligations
held by it. The Fund may also employ new  investment  techniques  involving such
options.  In  addition,  the Fund may enter into  currency  and other  financial
futures contracts and related options  transactions for hedging purposes and not
for  speculation  and  employ new  investment  techniques  with  respect to such
futures contracts and related options. In addition,  the Fund may also invest in
obligations  denominated  in foreign  currencies  that are exempt  from  federal
income tax.

  In addition to the options and futures  contracts  mentioned above, only if it
is consistent with its investment objective, the Fund may also invest in certain
other types of "derivative instruments," including structured securities.

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

  From time to time,  proposals  have been  introduced  before  Congress for the
purpose of  restricting  or  eliminating  the federal  income tax  exemption for
interest on municipal  bonds,  and similar  proposals  may be  introduced in the
future. If such a proposal were enacted, the availability of municipal bonds for
investment by the Fund and the value of the Fund's portfolio could be materially
affected, in which event the Fund would re-evaluate its investment objective and
policies and consider changes in the structure of the Fund or dissolution.

  Investment in some securities may involve special considerations. For example,
the Fund may invest in master demand notes,  a type of commercial  paper that is
redeemable on demand,  but for which there is no secondary market.  Furthermore,
the  Fund  may  enter  into  repurchase   agreements  with  domestic  banks  and
broker-dealers. The payment of interest accrued by the Fund under its repurchase
agreements is dependent on the ability of the seller to perform its  obligations
to the Fund. If the seller of a repurchase  agreement  refused to repurchase the
securities  underlying  the  agreement,  the  Fund  would  suffer  a loss if the
proceeds from the sale of the  underlying  securities  were less than the agreed
upon  repurchase  price,  and the loss would be increased by any cost of selling
the  securities.  If the  defaulting  seller  filed  for  bankruptcy  or  became
insolvent,  sale of the securities might be delayed by pending court action.  In
such a case,  it is not clear that the Fund would have the right,  against other
claimants, to keep the securities.

   
  In addition,  the Fund may,  notwithstanding  any other  investment  policy or
restriction,  invest all of its assets in the  securities  of a single  open-end
management investment company with substantially the same fundamental investment
objectives,  policies and  restrictions as the Fund. The Fund does not currently
intend to  implement  this policy and would do so only if the  Trustees  were to
determine  such  action  to  be in  the  best  interest  of  the  Fund  and  its
shareholders.  In the event of such  implementation,  the Fund will  comply with
such requirements as to written notice to shareholders as are then in effect.
    

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

FUNDAMENTAL NATURE OF INVESTMENT OBJECTIVE

  The investment  objective of the Fund set forth above is  fundamental  and may
not be changed without the vote of a majority 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).  Of course,  there can be no assurance that the
Fund will achieve its investment  objective  since there is uncertainty in every
investment.
- ------------------------------------------------------------------------------
INVESTMENT RESTRICTIONS
- ------------------------------------------------------------------------------

   
  The Fund has adopted the fundamental  restrictions summarized below, which may
not be changed  without the  approval  of a majority  of the Fund's  outstanding
shares.  These  restrictions and certain other fundamental  restrictions are set
forth in detail in the statement of additional information.

  Generally  the Fund may not do the  following:  (1) invest more than 5% of its
total assets in the securities of any one issuer; (2) borrow money,  except that
the Fund may borrow money from banks for emergency or extraordinary  purposes in
aggregate amounts up to one-third  (normally less than 5%) of its net assets and
enter into reverse repurchase agreements;  (3) pledge more than 15% of its total
assets to secure  borrowings;  (4) invest  more than 25% of its total  assets in
securities of issuers in the same industry;  and (5) invest more than 10% of its
total assets in repurchase agreements maturing in more than seven days.
    

- ------------------------------------------------------------------------------
RISK FACTORS
- ------------------------------------------------------------------------------

  The  risk  inherent  in  investing  in the  Fund is that  risk  common  to any
security,  that the net asset  value will  fluctuate  in  response to changes in
economic  conditions,   interest  rates  and  the  market's  perception  of  the
underlying portfolio securities of the Fund.

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

- ------------------------------------------------------------------------------
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 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 is  arrived  at by  determining  the value of all of the  Fund's
assets,  subtracting  all  liabilities  and dividing the result by the number of
shares outstanding.

  The Fund  values  municipal  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 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.  Short-term  instruments
maturing  in more  than  sixty  days for which  market  quotations  are  readily
available are valued at current market value.  Short- term instruments  maturing
in more than sixty days when  purchased  that are held on the sixtieth day prior
to maturity  are valued at  amortized  cost  (market  value on the  sixtieth day
adjusted for  amortization  of premium or accretion of  discount),  which,  when
combined  with  accrued  interest,  approximates  market  and  which in any case
reflects  fair value as  determined  by the Fund's 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  using  methods
prescribed 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 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 distribution would be (1) declared
in October, November, or December to shareholders of record in such a month, (2)
paid by the following  January 31, and (3)  includable in the taxable  income of
shareholders for the year in which such distributions were declared. If the Fund
qualifies and if it distributes  substantially  all of its net investment income
and net  capital  gains,  if any,  to  shareholders,  it will be relieved of any
federal income tax liability.

  As of April 1,  1995,  in  compliance  with the  recent  ruling  issued by the
Internal  Revenue  Service  ("IRS") the Fund treats its 12b-1 fees as  operating
expenses, instead of as capital charges.

  The Fund intends to declare  dividends  from net  investment  income daily and
distribute  to its  shareholders  such  dividends  monthly  and to  declare  and
distribute all net realized long-term capital gains annually.  All dividends and
distributions will be payable in shares or, at the option of the shareholder, in
cash. All shareholders may receive  dividends in shares without being subject to
a deferred sales charge when such shares are redeemed. Shareholders who have not
opted prior to the record date for any  distribution  to receive  cash will have
the number of such shares  determined on the basis of the Fund's net asset value
per share computed at the end of the day on the record date after adjustment for
the  distribution.  Net asset value is used in computing the number of shares in
both capital gains and income distribution reinvestments. There is a possibility
that  shareholders may lose the tax-exempt status on accrued income on municipal
bonds if shares of the Fund are redeemed  before a dividend  has been  declared.
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
capital  gains and income  distributions  in shares.  Instructions  continue  in
effect until changed in writing.

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

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

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

  Some or all of the Fund's  exempt  interest  dividends may be subject to state
income taxes. The Fund will report to shareholders on a state by state basis the
sources of its exempt interest dividends.

  Since none of the  Fund's  income  will  consist of  corporate  dividends,  no
distributions will qualify for the 70% corporate dividends received deduction.

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

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

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

  For the fiscal year ended December 31, 1994,  approximately 100% of the Fund's
income  distributions  were designated as exempt from federal income taxes.  The
Fund  advises  its  shareholders  annually  as to the  federal tax status of all
distributions made during the year.

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

  Pursuant to its Investment Management Agreement with the Fund (the "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
(the "Investment Advisory Agreement"),  under which Keystone provides 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.

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

  Keystone  Investments  is a  corporation  predominantly  owned by  former  and
current  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 Mutual Funds.

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

  For the  fiscal  year ended  December  31,  1994,  the Fund paid or accrued to
Keystone Management investment management fees of $5,941,545,  which represented
0.43%  of the  Fund's  average  net  assets.  Of such  amount  paid to  Keystone
Management,  $5,050,313  was paid to Keystone for its  services to the Fund.  In
addition, the Fund reimbursed Keystone Management $2,029,000,  which represented
0.15% of the Fund's average net assets, in connection with reimbursable expenses
paid  by  Keystone  Management  on  behalf  of the  Fund  under  the  Management
Agreement.  For the fiscal year ended  December 31, 1994,  the total fee paid to
Keystone  Management by the Fund for investment  management  and  administrative
services fees was $7,970,545,  which represented 0.58% of the Fund's average net
assets.

  Keystone, Keystone Management and the Fund have each adopted a Code of
Ethics incorporating policies on personal securities trading as recommended by
the Investment Company Institute.

FUND EXPENSES
  In addition to the investment  advisory and management  fees discussed  above,
the  principal  expenses  that the Fund is expected to pay include,  but are not
limited to,  expenses of its transfer  agent,  its custodian and its independent
auditors, expenses under its Distribution Plan, fees of its independent Trustees
("Independent Trustees"), expenses of shareholders' and Trustees' meetings, fees
payable to government agencies, including registration and qualification fees of
the Fund and its shares under  federal and state  securities  laws,  expenses of
preparing,  printing and mailing Fund prospectuses,  notices,  reports and proxy
material and certain extraordinary  expenses. In addition to such expenses,  the
Fund pays its brokerage commissions,  interest charges and taxes. For the fiscal
year ended  December 31, 1994,  the Fund paid 1.55% of its average net assets in
expenses.

  During the fiscal year ended  December 31,  1994,  the Fund paid or accrued to
Keystone  Investments  $23,917 for certain  accounting  services and to Keystone
Investor  Resource  Center,  Inc.  ("KIRC"),  the Fund's  transfer  and dividend
disbursing  agent,  $1,418,000 for certain  transfer agent  services.  KIRC is a
wholly-owned  subsidiary of Keystone.  The amount for transfer agent services is
included in the amount of  reimbursable  expenses  paid on behalf of the Fund by
Keystone Management.

PORTFOLIO MANAGER

addition,  broker-dealers  may from  time to time be  affiliated  with the Fund,
Keystone  Management,  Keystone,  the  Fund's  principal  underwriter  or  their

- ------------------------------------------------------------------------------
HOW TO BUY SHARES
- ------------------------------------------------------------------------------

  Except as  noted  below,  the Fund  generally  offers  its  shares  by  direct
investment only to  shareholders  who  beneficially  own shares of the Fund. The
Fund also offers its shares through  exchanges to  shareholders of certain other
funds in Keystone  Investments family of mutual Funds. As previously  mentioned,
the Fund will be open  however,  to new  investors  during the Special  Offering
Period.

  Shares of the Fund may be purchased from any broker-dealer  that has a selling
agreement   with   Keystone   Investment    Distributors   Company   ("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.

  Shares become entitled to income distributions  declared on the first business
day following receipt by the Fund's transfer agent of payment for the shares. It
is the  investor's  responsibility  to see that  his  dealer  promptly  forwards
payment to the  Principal  Underwriter  for shares being  purchased  through the
dealer.
    
  Orders for shares  received  by  broker-dealers  prior to that day's  close of
trading  on the  Exchange  and  transmitted  to the Fund  prior to its  close of
business  that day will receive the offering  price equal to the net asset value
per share  computed  at the close of  trading on the  Exchange  on the same day.
Orders  received  by  broker-dealers  after that  day's  close of trading on the
Exchange and  transmitted to the Fund prior to the close of business on the next
business day will receive the next business  day's offering  price.  The initial
purchase  must be at least  $10,000.  During the Special  Offering  Period,  the
minimum initial investment will be $1,000.  Purchase payments are fully invested
at net asset  value.  There are no sales  charges on purchases of Fund shares at
the time of purchase.

   
CONTINGENT DEFERRED SALES CHARGE
  With certain  exceptions,  when shares are redeemed within four calendar years
after their purchase, a contingent deferred sales charge may be imposed at rates
ranging from a maximum of 4% of amounts  redeemed  during the  calendar  year of
purchase to 1% of amounts redeemed during the third calendar year after the year
of purchase.  No contingent deferred sales charge is imposed on amounts redeemed
thereafter  or  on  shares  purchased  through  reinvestment  of  dividends  and
distributions. If imposed, the contingent deferred sales charge is deducted from
the redemption  proceeds  otherwise  payable to the  shareholder.  Since July 8,
1992, the  contingent  deferred sales charge  attributable  to shares  purchased
prior to  January  1, 1992 has been  retained  by the Fund,  and the  contingent
deferred sales charge attributable to shares purchased after January 1, 1992 is,
to the  extent  permitted  by NASD  rules,  paid to the  Principal  Underwriter.
Accordingly,  for the fiscal year ended  December  31, 1994,  the Fund  retained
$97,865 and the  Principal  Underwriter  received  $745,076,  in deferred  sales
charges.
    

  The contingent  deferred sales charge is a declining  percentage of the lesser
of (1) the net asset value of the shares  redeemed or (2) the total cost of such
shares.  No  contingent  deferred  sales  charge is imposed  when a  shareholder
redeems amounts derived from (1) increases in the value of his account above the
total 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;  or (3) shares held in all or
part of more than four consecutive calendar years.

   
  In determining  whether a contingent  deferred sales charge is payable and, if
so, the percentage charge applicable, it is assumed that shares held the longest
are the first to be  redeemed.  There is no  deferred  sales  charge  imposed on
permitted   exchanges  of  shares  between  Keystone  funds  that  have  adopted
distribution  plans  pursuant to Rule 12b-1 under the 1940 Act.  Moreover,  when
shares of one such fund have been exchanged for shares of another such fund, for
purposes of any future  contingent  deferred sales charge,  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 DEFERRED SALES CHARGE
  Shares also may be sold,  to the extent  permitted by  applicable  law, at net
asset value without the payment of  commissions  or the imposition of a deferred
sales charge upon redemption of Fund shares to (1) certain officers,  Directors,
Trustees and employees of the Fund, Keystone Management, Keystone and certain of
their affiliates; (2) registered representatives of firms with dealer agreements
with the  Principal  Underwriter;  and (3) a bank or  trust  company  acting  as
trustee for a single account.

  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)  involuntary  redemptions of accounts having an aggregate net asset value of
less than $1,000; (3) automatic  withdrawals under an automatic  withdrawal plan
of up to 1 1/2% per month of the  shareholder's  initial  account  balance;  (4)
withdrawals  consisting of loan proceeds to a retirement plan  participant;  (5)
financial  hardship  withdrawals made by a retirement plan  participant;  or (6)
withdrawals  consisting of returns of excess  contributions  or excess  deferral
amounts made to a retirement plan participant.

- ------------------------------------------------------------------------------
DISTRIBUTION PLAN
- ------------------------------------------------------------------------------

  The Fund bears some of the costs of selling  its shares  under a  Distribution
Plan  adopted on June 1, 1983  pursuant  to Rule 12b-1  under the 1940 Act.  The
Fund's  Distribution  Plan  provides  that  the Fund may  expend  up to  0.3125%
quarterly (approximately 1.25% annually) of average daily net asset value of its
shares to pay distribution  costs for sales of its shares and to pay shareholder
service fees. The NASD currently limits such annual expenditures to 1%, of which
0.75%  may be used to pay such  distribution  costs and 0.25% may be used to pay
shareholder  service fees.  The aggregate  amount that the Fund may pay for such
distribution  costs is limited to 6.25% of gross share sales since the inception
of the  Fund's  Distribution  Plan plus  interest  at the prime  rate plus 1% on
unpaid  amounts  thereof  (less any  contingent  deferred  sales charges paid by
shareholders to the Principal Underwriter).

  Payments  under the  Distribution  Plan are  currently  made to the  Principal
Underwriter  (which may reallow  all or part to others  such as dealers)  (1) as
commissions for Fund shares sold and (2) as shareholder  service fees in respect
to shares  maintained  by the  recipients  outstanding  on the Fund's  books for
specified  periods.  Amounts paid or accrued to the Principal  Underwriter under
(1) and (2) in the aggregate may not exceed the annual  limitations  referred to
above.  The  Principal  Underwriter  generally  reallows  to brokers or others a
commission  equal to 3% of the price  paid for each Fund share sold as well as a
shareholder  service  fee at a rate of 0.25% per annum of the net asset value of
shares  maintained by such  recipients  outstanding on the books of the Fund for
specified periods.

  During the Special Offering Period, the Principal  Underwriter will reallow an
increased  commission  equal to 4% of the price paid for each Fund share sold to
those   broker/dealers   or  others   who   allow   their   individual   selling
representatives  to participate in the additional 1% commission.  Broker/dealers
or  others  not  allowing  their  individual   selling   representatives  to  so
participate will receive the normal 3% commission.

  If the Fund is unable to pay the  Principal  Underwriter a commission on a new
sale  because the annual  maximum  (0.75% of average  daily net assets) has been
reached, the Principal Underwriter intends, but is not obligated, to continue to
accept  new  orders  for  the  purchase  of  Fund  shares  and to pay or  accrue
commissions  and  service  fees to dealers in excess of the amount it  currently
receives from the Fund. While the Fund is under no contractual obligation to pay
the  Principal  Underwriter  such  amounts  that  exceed the  Distribution  Plan
limitation,  the  Principal  Underwriter  intends  to seek full  payment of such
charges  from the Fund  (together  with  interest  at the rate of prime plus one
percent) at such time in the future as, and to the extent that,  payment thereof
by the  Fund  would  be  within  permitted  limits.  The  Principal  Underwriter
currently  intends to seek  payment of  interest  only on such  charges  paid or
accrued by the Principal  Underwriter  subsequent to July 7, 1992. 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 the Distribution Plan. If the 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.  If
under  changing  conditions  the Principal  Underwriter  were to seek payment of
interest  on such  amounts,  any such  interest  payments  also would have to be
approved by the Independent Trustees (and possibly the shareholders).

  During the fiscal year ended December 31, 1994, the Fund recovered  $97,865 in
deferred sales charges. During the year, the Fund paid the Principal Underwriter
$13,324,192  (0.98% of the Fund's average daily net asset value during the year)
under the Distribution  Plan. The amount paid by the Fund under its Distribution
Plan,  net of  deferred  sales  charges,  was  $13,227,327  (0.97% of the Fund's
average daily net asset value during the year).  During the year,  the Principal
Underwriter received $9,126,418,  after payments of commissions on new sales and
service fees to dealers and others of $4,197,774.

  The amounts and purposes of expenditures  under the Distribution  Plan must be
reported to the Independent  Trustees  quarterly.  The Independent  Trustees may
require or approve  changes in the  operation of the  Distribution  Plan and may
require that total  expenditures by the Fund under the Distribution Plan be kept
within limits lower than the maximum amount permitted by the  Distribution  Plan
as stated above. If such costs are not limited by the Independent Trustees, such
costs  could,  for some period of time,  be higher than such costs  permitted by
most other plans presently adopted by other investment companies.
    

  The  Distribution  Plan may be  terminated  at any time by vote of the  Fund's
Independent  Trustees or by vote of a majority of the outstanding  voting shares
of the Fund. Any change in the Distribution Plan that would materially  increase
the  distribution  expenses of the Fund  provided for in the  Distribution  Plan
requires shareholder approval.  Otherwise,  the Distribution Plan may be amended
by votes of the majority of both (1) the Fund's Trustees and (2) the Independent
Trustees,  cast in person at a meeting  called for the purpose of voting on such
amendment.

  While the Distribution  Plan is in effect,  the Fund is required to commit the
selection  and  nomination  of  candidates  for  Independent   Trustees  to  the
discretion of the Independent Trustees.

  Whether  any  expenditure  under the  Distribution  Plan is subject to a state
expense  limit depends 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 state expense limits.

   
  Upon written notice to dealers, the Principal Underwriter,  at its own expense
may  periodically  sponsor  programs  which  offer  additional  compensation  in
connection  with sales of Fund  shares.  Participation  in such  programs may be
available to all dealers or to selected dealers who have sold or are expected to
sell  significant  amounts of shares.  Additional  compensation may also include
financial  assistance  to  dealers  in  connection  with  preapproved  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.

  The Principal  Underwriter  may also pay a transaction fee (up to the level of
payment allowed to dealers for the sale of shares,  as described above) to banks
and other financial service 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.

- ------------------------------------------------------------------------------
HOW TO REDEEM SHARES
- ------------------------------------------------------------------------------

  Fund  shares may be redeemed  for cash at the  redemption  value upon  written
order by the  shareholder(s) to the Fund, c/o Keystone Investor Resource Center,
Inc., Box 2121, Boston,  Massachusetts 02106-2121,  and presentation to the Fund
of a properly endorsed share  certificate if certificates have been issued.  The
signature(s) of the shareholder(s) on the written order and certificates must be
guaranteed.  The redemption  value is the net asset value adjusted for fractions
of a cent and may be more or less than the  shareholder's  cost  depending  upon
changes in the value of the Fund's  portfolio  securities  between  purchase and
redemption.  A deferred  sales  charge may be imposed by the Fund at the time of
redemption  of certain  shares as  explained in "How to Buy Shares." If imposed,
the deferred  sales charge is deducted from the  redemption  proceeds  otherwise
payable to the shareholder.

  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 may delay the mailing of
a redemption  check or the wiring of redemption  proceeds until good payment has
been  collected for the purchase of such shares.  This may take up to 15 days or
more. Any delay may be avoided by purchasing shares with a certified check drawn
on a U.S.  bank or by bank wire of funds.  Although  the mailing of a redemption
check or the wiring of redemption proceeds may be delayed,  the redemption value
will be  determined  and the  redemption  processed  in the  ordinary  course of
business upon receipt of proper documentation.  In such a case, after redemption
and prior to the release of the proceeds,  no appreciation or depreciation  will
occur in the value of the redeemed  shares,  and no interest will be paid on the
redemption proceeds.  If the mailing of a redemption has been delayed, the check
will be mailed or the  proceeds  wired  promptly  after  good  payment  has been
collected.

   
  The Fund computes the redemption value at the close of the Exchange at the end
of  the  day  on  which  it has  received  all  proper  documentation  from  the
shareholder.  Payment  of the  amount  due on  redemption,  less any  applicable
deferred  sales  charge,  will be made within seven days  thereafter,  except as
noted above.

  Shareholders  also may redeem their shares through their  broker-dealers.  The
Principal Underwriter,  acting as agent for the Fund, stands ready to repurchase
Fund shares upon orders from dealers as follows: redemption requests received by
broker-dealers  prior  to that  day's  close  of  trading  on the  Exchange  and
transmitted to the Fund prior to its close of business that day will receive the
net asset value per share  computed  at the close of trading on the  Exchange on
the same day.  Redemption  requests received by broker-dealers  after that day's
close of trading on the Exchange and  transmitted to the Fund prior to the close
of business on the next  business day will receive the next  business  day's net
asset value price. The Principal  Underwriter will pay the redemption  proceeds,
less any  applicable  deferred  sales  charge,  to the dealer  placing the order
within seven days thereafter, assuming it has received proper documentation. The
Principal  Underwriter  charges no fees for this service,  but the shareholder's
broker-dealer may do so.

  For the protection of shareholders,  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 and KIRC may
waive this  requirement  but may also  require  additional  documents in certain
cases.  Currently,  the requirement for a signature guarantee has been waived on
redemptions of $50,000 or less where the account  address of record has been the
same for a minimum  period of 30 days.  The Fund and KIRC  reserve  the right to
withdraw this waiver at any time.
    

  If the Fund receives a redemption or repurchase order but the shareholder
has 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 the shareholder and process the order the day it
receives such information.

TELEPHONE
  Under ordinary  circumstances,  you may redeem up to $50,000 from your account
by  telephone  by  calling  toll free  1-800-343-2898.  To  engage in  telephone
transactions generally, you must complete the appropriate sections of the Fund's
application.

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

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.

SMALL ACCOUNTS
  Because of the high cost of maintaining small accounts,  the Fund reserves the
right to redeem your account if its value has fallen below  $1,000,  the current
minimum  investment  level, as a result of your redemptions (but not as a result
of market  action).  You will be  notified  in  writing  and  allowed 60 days to
increase the value of your account to the minimum  investment level. 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.  However,  the Fund has obligated itself under the
1940 Act to redeem for cash all shares of the Fund  presented for  redemption by
any one  shareholder  in any 90 day period up to the lesser of $250,000 or 1% of
the Fund's net assets at the beginning of such 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 when these securities are sold.

1-800-343-2898  or by writing  KIRC at Box 2121,  Boston,  Massachusetts  02106-
2121.  (See "How to Redeem  Shares"  for  additional  information  on  telephone
transactions.)

   
  Fund shares purchased by check may be exchanged for shares of the named funds,
other than KPMH or KTET,  after 15 days.  In order to  exchange  Fund shares for
shares of KPMH or KTET, a shareholder must have held Fund shares for a period of
at least six months. There is a $10.00 exchange fee for each exchange;  however,
there is no fee for  exchange  orders  received  by the Fund from an  individual
shareholder  over KARL. If the shares being tendered for exchange have been held
for less than four years and 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  shares of the Fund for shares of KLT will be  executed by
redeeming the shares of the Fund and  purchasing  shares of KLT at the net asset
value of KLT shares  determined  after the proceeds from such redemption  become
available,  which may be up to seven days after  such  redemption.  In all other
cases, orders for exchanges received by the Fund prior to 4:00 p.m. eastern time
on any day the funds are open for  business  will be executed at the  respective
net asset values  determined  as of the close of business  that day.  Orders for
exchanges  received  after 4:00 p.m.  eastern  time on any  business day will be
executed at the respective net asset values  determined at the close of the next
business day.
    

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

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

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

AUTOMATIC WITHDRAWAL PLAN
  Under an  Automatic  Withdrawal  Plan,  shareholders  may  arrange for regular
monthly or quarterly fixed  withdrawal  payments.  Each payment must be at least
$100 and may be as much as 1% per month or 3% per quarter of the total net asset
value  of the Fund  shares  in the  shareholder's  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 a shareholder's account.

OTHER SERVICES
  Under  certain  circumstances   shareholders  may,  within  30  days  after  a
redemption, reinstate their accounts at current net asset value.

PERFORMANCE DATA
- ------------------------------------------------------------------------------

  From time to time, the Fund may advertise "total return,"  "current yield" and
"tax equivalent yield." ALL FIGURES ARE BASED ON HISTORICAL EARNINGS AND ARE NOT
INTENDED TO  INDICATE  FUTURE  PERFORMANCE.  Total  return  refers to the Fund's
average annual compounded rates of return over specified  periods  determined by
comparing the initial  amount  invested to the ending  redeemable  value of that
amount.  The  resulting  equation  assumes  reinvestment  of all  dividends  and
distributions  and  deduction  of  all  recurring  charges   applicable  to  all
shareholder  accounts.  The deduction of the contingent deferred sales charge is
reflected  in the  applicable  years.  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.

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

   
  The Fund may also  include  comparative  performance  and general  mutual fund
industry information in advertising or marketing the Fund's shares, such as data
from Lipper Analytical Services, Inc., Morningstar,  Inc., CDS- Weisenberger and
Value Line or other financial and industry publications.

FUND SHARES
- ------------------------------------------------------------------------------

  The Fund  currently  issues one class of shares which  participate  equally in
dividends and distributions and have equal voting, liquidation and other rights.
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 redeemable,  transferable and freely assignable as collateral.  There are no
sinking fund provisions.  The Fund may establish additional classes or series of
shares.

  Shareholders  of the Fund are  entitled  to one vote for each full share owned
and fractional votes for fractional  shares. The Fund will have special meetings
from time to time as required under its  Declaration of Trust and under the 1940
Act. As provided in the Fund's Declaration of Trust, shareholders have the right
to remove  Trustees by an  affirmative  vote of  two-thirds  of the  outstanding
shares.  A  special  meeting  of the  shareholders  will be held when 10% of the
outstanding  shares request a meeting for the purpose of removing a Trustee.  As
prescribed  by Section 16(c) of the 1940 Act,  shareholders  may be eligible for
shareholder communication assistance in connection with the special meeting.

  Under  Massachusetts  law it is possible that a Fund  shareholder  may be held
personally liable for the Fund's obligations. 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.

CORPORATE AND MUNICIPAL BOND RATINGS

S&P CORPORATE AND MUNICIPAL BOND RATINGS

A.  MUNICIPAL NOTES

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

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

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

  Note ratings are as follows:

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

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

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

B.  TAX EXEMPT DEMAND BONDS

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

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

C. CORPORATE AND MUNICIPAL BOND RATINGS

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

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

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

  2. nature of and provisions of the obligation; and

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

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

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

D. BOND RATINGS ARE AS FOLLOWS:

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

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

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

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

  MOODY'S CORPORATE AND MUNICIPAL BOND RATINGS

A.  MUNICIPAL NOTES

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

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

  The note ratings are as follows:

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

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

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

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

B.  CORPORATE AND MUNICIPAL BOND RATINGS

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

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

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

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

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

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

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

FITCH CORPORATE AND MUNICIPAL RATINGS

A.  MUNICIPAL NOTES

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

  The note ratings are as follows:

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

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

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

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

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

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

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

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

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

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

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

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

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  acquired  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 will be deemed to
have a maturity equal to the longer of the period remaining to the next interest
rate  adjustment or the demand notice  period.  Because these types of notes are
direct lending  arrangements  between the lender and borrower,  such instruments
are not  normally  traded  and there is no  secondary  market  for these  notes,
although they are  redeemable  and thus  repayable by the borrower at face value
plus accrued  interest at any time.  Accordingly,  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 may invest in them only
if at the time of an investment  the issuer meets the criteria  established  for
commercial   paper  discussed  in  the  statement  of  additional   information.

REPURCHASE AGREEMENTS
  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
that 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
("SEC")  has taken the  position  that the 1940 Act  treats  reverse  repurchase
agreements as being included in the percentage limit on borrowings  imposed on a
fund.

"WHEN ISSUED" SECURITIES
  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. However, no payment or delivery is made by the Fund
until it receives payment or delivery from the other party to the transaction. A
separate  account  of  liquid  assets  equal  to  the  value  of  such  purchase
commitments  will be maintained  until payment is made.  When issued and delayed
delivery  agreements  are  subject  to risks from  changes  in value  based upon
changes in the level of interest rates, currency rates and other market factors,
both  before  and after  delivery.  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 consistent with
its  investment  objective  and policies  and not for the purpose of  investment
leverage.

LOANS OF SECURITIES TO BROKER-DEALERS
  The Fund may lend  securities  to brokers and dealers  pursuant to  agreements
requiring  that the loans be  continuously  secured by cash or securities of the
U.S. government,  its agencies or instrumentalities,  or any combination of cash
and such  securities,  as collateral equal at all times in value to at least the
market value of the securities  loaned.  Such securities  loans will not be made
with  respect  to 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 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  in  furtherance  of its  investment  objective.
Derivatives are financial  contracts whose value depends on, or is derived from,
the value of an underlying asset,  reference rate or index. These assets, rates,
and indices may include bonds, stocks, mortgages,  commodities,  interest rates,
currency exchange rates, bond indices and stock indices. Derivatives can be used
to earn income or protect  against  risk, or both.  For example,  one party with
unwanted  risk may agree to pass that risk to  another  party who is  willing to
accept the risk, the second party being  motivated,  for example,  by the desire
either to earn income in the form of a fee or premium from the first  party,  or
to reduce its own unwanted  risk by  attempting to pass all or part of that risk
to the first party.

  Derivatives  can be used by  investors  such as the  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.  Each of these  uses  entails  greater  risk than if
derivatives  were used  solely  for  hedging  purposes.  The Fund  uses  futures
contracts and related options 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 and futures, is provided
later in this  section  and is provided in the Fund's  statement  of  additional
information.

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

  While the judicious use of derivatives by experienced investment managers such
as Keystone can be beneficial,  derivatives  also involve risks  different from,
and, in certain  cases,  greater than, the risks  presented by more  traditional
investments.  Following is a general  discussion  of important  risk factors and
issues concerning the use of derivatives that investors should understand before
investing in 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  which are available
for writing options,  the Fund may be unable to write additional  options unless
it sells a portion of its portfolio  holdings to obtain new  securities  against
which it can write options. If this were to occur, higher portfolio turnover and
correspondingly  greater  brokerage  commissions and other transaction costs may
result. However, the Fund does not expect 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
security or dispose of assets  held in a  segregated  account  until the options
expire or are exercised.

  An option position may be closed out only in a secondary  market for an option
of the same series.  Although 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 generally are
listed  on  national  securities  exchanges.  Exchanges  on which  such  options
currently  are traded  include the Chicago  Board  Options  Exchange and the New
York,  American,  Pacific  and  Philadelphia  Stock  Exchanges.  Options on some
securities may not be listed on any Exchange, but traded in the over-the-counter
market.  Options  traded in the  over-the-counter  market involve the additional
risk that securities  dealers  participating in such transactions  could fail to
meet  their  obligations  to  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 SEC 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 investment restriction relating to illiquid investments.

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 futures on
securities  or  currencies or  index-based  futures  contracts in order to hedge
against  changes in interest or exchange rates or securities  prices.  A futures
contract on securities  or currencies is an agreement to buy or sell  securities
or currencies at a specified price during a designated month. A futures contract
on a securities  index does not involve the actual  delivery of securities,  but
merely  requires  the  payment  of a cash  settlement  based on  changes  in the
securities  index.  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 establish
what is believed  by  Keystone  to be a  favorable  price and rate of return for
securities  or  favorable  exchange  rate for  currencies  the Fund  intends  to
purchase.

  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 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. The
Fund may also  purchase  and sell  options  related  to  foreign  currencies  in
connection  with  hedging  strategies.

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

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

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

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

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

                       THE FUND'S OBJECTIVE AND POLICIES
- --------------------------------------------------------------------------------

         The Fund's  investment  objective is to provide  shareholders  with the
highest  possible  current  income,  exempt from  federal  income  taxes,  while
preserving  capital.  The Fund invests primarily in municipal bonds but also may
invest in certain other  securities as described in the Appendix  hereto and the
"Additional Investment Information" section of the Fund's prospectus.

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,  as  defined in the
Investment  Company  Act of 1940 (the "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
- --------------------------------------------------------------------------------

   
         None of the  restrictions  enumerated in this  paragraph may be changed
without a vote of the holders of a 1940 Act  majority of the Fund's  outstanding
shares. The Fund will not do the following:
    

         (1)  purchase  securities  on  margin,  but the  Fund may  obtain  such
short-term  credits as may be necessary for the clearance of purchases and sales
of securities;

   
         (2) 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  that 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;
    

         (3) borrow money,  except that the Fund may (a) borrow money from banks
for emergency or extraordinary  purposes in aggregate amounts up to one-third of
its net assets, and (b) enter into reverse repurchase agreements;

         (4)  pledge,  mortgage  or  hypothecate  its  assets  except  to secure
indebtedness  permitted by subparagraph (3) above,  with pledged assets to be no
more than 15% of its total assets;  the Fund  understands that pledges in excess
of  approximately  6% of its net assets  would  result in its  inability to sell
additional  shares in one state;  however,  the Fund has no present intention of
exceeding this limit;

         (5) purchase any security other than United States ("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,  including  industrial  development bonds from
the same  facility  or  similar  types of  facilities;  governmental  issuers of
municipal  bonds are not  regarded  as members of an  industry  and the Fund may
invest more than 25% of its assets in industrial development bonds;

         (6) purchase any security, other than U.S. government securities, if as
a result more than 5% of the Fund's total assets would be invested in securities
of the issuer,  or the Fund would hold more than 10% of the voting securities of
the issuer;

         (7) invest for the purpose of exercising  control over or management of
any company;

         (8) invest in securities of other investment companies,  except as part
of a merger,  consolidation,  purchase of assets or similar transaction approved
by the Fund's shareholders;

   
         (9) 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  that invest in real estate,  and may engage in currency
or other financial futures and related options transactions;

         (10) act as an  underwriter  except to the extent that,  in  connection
with the  disposition  of its portfolio  investments,  it may be deemed to be an
underwriter under federal  securities laws; or purchase  securities that are not
readily marketable except for repurchase agreements;
    

         (11) purchase or retain securities of an issuer if, to the knowledge of
the  Fund,  an  officer,  Trustee  or  Director  of the  Fund or  Keystone  owns
beneficially  more than 1/2 of 1% of the shares or securities of such issuer and
all such  officers,  Trustees and  Directors  owning more than 1/2 of 1% of such
shares or securities together own more than 5% of such shares or securities;

         (12) purchase  securities of any issuer if the person  responsible  for
payment,  together  with any  predecessor,  has been in operation  for less than
three years if, as a result,  the aggregate of such investments  would exceed 5%
of the Fund's total assets;  provided,  however, that this restriction shall not
apply to U.S.  government  securities or to any  obligation the payment of which
involves the credit and taxing power of any person authorized to issue municipal
bonds;

         (13) invest in interests in oil, gas or other  mineral  exploration  or
development programs;

         (14)  make  loans,  except  to the  extent  that the  purchase  of debt
instruments  or  repurchase  agreements  may be deemed  to be loans;  repurchase
agreements  maturing  in more than  seven days will not exceed 10% of the Fund's
total assets; and

         (15) purchase securities of foreign issuers.

         The  foregoing  percentage  restrictions  will apply at the time of the
purchase of a security and shall not be considered  violated unless an excess or
deficiency  occurs or exists  immediately after and as a result of a purchase of
such security.  For the purpose of limitations  (5) and (6), the Fund will treat
each state,  territory and possession of the U.S., the District of Columbia and,
if its assets and  revenues  are  separate  from those of the entity or entities
creating it, each political  subdivision,  agency and instrumentality of any one
(or more,  as in the case of a multistate  authority or agency) of the foregoing
as an  issuer of all  securities  that are  backed  primarily  by its  assets or
revenues;  each company as an issuer of all securities that are backed primarily
by its assets or revenues;  and each of the  foregoing  entities as an issuer of
all securities that it guarantees;  provided,  however,  that for the purpose of
limitation  (6) no entity shall be deemed to be an issuer of a security  that it
guarantees  so long as no more than 10% of the  Fund's  total  assets  (taken at
current  value)  are  invested  in  securities  guaranteed  by  the  entity  and
securities of which it is otherwise deemed to be an issuer.

         The Fund does not presently intend to invest more than 25% of its total
assets in (1) municipal bonds of a single state and its  subdivisions,  agencies
and  instrumentalities;  of a single territory or possession of the U.S. and its
subdivisions, agencies or instrumentalities;  or of the District of Columbia and
any subdivision,  agency or instrumentality  thereof; or (2) municipal bonds the
payment of which depends on revenues  derived from a single  facility or similar
types of facilities.  Since certain municipal bonds may be related in such a way
that an economic, business or political development or change affecting one such
security could  likewise  affect the other  securities,  a change in this policy
could  result  in  increased   investment  risk,  but  no  change  is  presently
contemplated.  The  Fund  may  invest  more  than  25% of its  total  assets  in
industrial development bonds.


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

   
         The Fund  believes that reliable  market  quotations  generally are not
readily  available  for  purposes  of  valuing  municipal  bonds.  As a  result,
depending on the particular municipal bonds owned by the Fund, it is likely that
most of the  valuations  for such  bonds  will be based  upon  their  fair value
determined  under  procedures  that have been approved by the Board of Trustees.
Non-tax exempt  securities for which market quotations are readily available are
valued on a consistent  basis at that price  quoted that,  in the opinion of the
Board of Trustees or the person  designated by the Board of Trustees to make the
determination,  most  nearly  represents  the  market  value  of the  particular
security.  Short-term  investments  that 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;  and short-term  investments  maturing in more than sixty
days when  purchased  that are held on the  sixtieth  day prior to maturity  are
valued  at  amortized  cost  (market  value on the  sixtieth  day  adjusted  for
amortization  of premium or accretion of  discount),  which,  when combined with
accrued  interest,  approximates  market and which,  in 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 using methods  prescribed by the Fund's Board
of Trustees.


- --------------------------------------------------------------------------------
                                 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
may be imposed at the time of  redemption  of certain  Fund  shares  within four
calendar years after their purchase.  If imposed,  the contingent deferred sales
charge  is  deducted  from the  redemption  proceeds  otherwise  payable  to the
shareholder.  Since July 8, 1992,  the  deferred  sales charge  attributable  to
shares purchased prior to January 1, 1992 has been retained by the Fund, and the
deferred sales charge attributable to shares purchased after January 1, 1992 is,
to the extent  permitted by National  Association  of Securities  Dealers,  Inc.
("NASD") rules, paid to the Principal Underwriter.  Accordingly,  for the fiscal
year ended  December  31,  1994,  the Fund  retained  $97,865 and the  Principal
Underwriter received $745,076 in deferred sales charges.

         The contingent  deferred sales charge is a declining  percentage of the
lesser of (1) the net asset  value of the shares  redeemed or (2) the total cost
of such  shares.  No  contingent  deferred  sales  charge  is  imposed  when the
shareholder  redeems  amounts  derived  from (1)  increases  in the value of his
account  above the total 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;  or (3) shares
held in all or part of more than four consecutive calendar years.
    

         Subject to the limitations  stated above, the Fund imposes a contingent
deferred  sales  charge  according  to the  following  schedule:  4% of  amounts
redeemed during the calendar year of purchase; 3% of amounts redeemed during the
calendar  year after the year of  purchase;  2% of amounts  redeemed  during the
second  calendar  year after the year of  purchase;  and 1% of amounts  redeemed
during  the third  calendar  year  after  the year of  purchase.  No  contingent
deferred sales charge is imposed on amounts redeemed thereafter.

   
         The following  example will  illustrate the operation of the contingent
deferred  sales  charge.  Assume  that an investor  makes a purchase  payment of
$10,000  during the calendar  year 1995 and on a given date in 1996 the value of
the investor's account has grown through investment performance and reinvestment
of distributions  to $12,000.  On such date in 1996 the investor could redeem up
to $2,000 ($12,000 minus $10,000) without incurring a deferred sales charge. If,
on such date, the investor  should redeem $3,000,  a deferred sales charge would
be  imposed  on $1,000 of the  redemption  (the  amount by which the  investor's
account was reduced by the redemption  below the amount of the initial  purchase
payment).  The charge would be imposed at the rate of 3% because the  redemption
is made during the  calendar  year after the calendar  year of  purchase,  for a
total deferred sales charge of $30.


         In  determining  whether a contingent  deferred sales charge is payable
and, if so, the percentage charge applicable, it is assumed that shares held the
longest are the first to be  redeemed.  There is no  contingent  deferred  sales
charge  imposed on permitted  exchanges of shares  between funds in the Keystone
Investments Family of Mutual Funds that have adopted distribution plans pursuant
to Rule 12b-1  under the 1940 Act.  Moreover,  when shares of one such fund have
been  exchanged  for shares of another  such fund,  for  purposes  of any future
contingent  deferred  sales  charge,  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.

         Shares also may be sold,  to the extent  permitted by  applicable  law,
regulations,  interpretations  or  exemptions,  at net asset  value  without the
imposition of a deferred sales charge upon redemption of shares to (1) officers,
Directors,  Trustees,  full-time employees and sales representatives of Keystone
Management, Inc. ("Keystone Management"), Keystone Investment Management Company
("Keystone")  (formerly  known as  Keystone  Custodian  Funds,  Inc.),  Keystone
Investments,  Inc. ("Keystone  Investments")  (formerly known as Keystone Group,
Inc.),  Harbor Capital  Management  Company,  Inc.,  their  subsidiaries and the
Principal  Underwriter who have been such for not less than ninety days; and (2)
the  pension and  profit-sharing  plans  established  by said  companies,  their
subsidiaries  and  affiliates,  for the  benefit of their  officers,  Directors,
Trustees, full-time employees and sales representatives, 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.

         In  addition,  no  contingent  deferred  sales  charge is  imposed on a
redemption  of  shares of the Fund  purchased  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, any fund in the Keystone Fund Family,
Keystone  Precious Metals  Holdings,  Inc.,  Keystone  International  Fund Inc.,
Keystone Tax Exempt Trust, Keystone Liquid Trust and/or any fund in the Keystone
America Fund Family is at least $500,000 and any commission paid by the Fund and
such other funds 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 a
redemption  of shares of the Fund in the event of (1) death or disability of the
shareholder;  (2)  involuntary  redemptions of accounts  having an aggregate net
asset value of less than $1,000;  (3) automatic  withdrawals  under an automatic
withdrawal plan of up to 1 1/2% per month of the  shareholder's  initial account
balance;  (4)  withdrawals  consisting  of loan  proceeds to a  retirement  plan
participant;  (5)  financial  hardship  withdrawals  made by a  retirement  plan
participant; or (6) withdrawals consisting of returns of excess contributions or
excess deferral amounts made to a retirement plan participant.
    


- --------------------------------------------------------------------------------
                               DISTRIBUTION PLAN
- --------------------------------------------------------------------------------

         Rule 12b-1 under the 1940 Act permits investment companies, such as the
Fund to use their assets to bear expenses of  distributing  their shares if they
comply  with  various  conditions,  including  adoption of a  distribution  plan
containing  certain provisions set forth in Rule 12b-1. On January 19, 1983, the
Fund's  Distribution  Plan  described  below was approved by the Fund's Board of
Trustees, including a majority of the Trustees who are not interested persons of
the Fund as defined in the 1940 Act  ("Independent  Trustees")  and the Trustees
who have no direct or indirect  financial  interest in the Distribution  Plan or
any agreement related thereto (the "Rule 12b-1 Trustees" who are the same as the
Independent  Trustees).  On May 27, 1983, the Distribution  Plan was approved by
the Fund's shareholders, and it became effective on June 1, 1983.

   
         The Fund's  Distribution  Plan  provides that the Fund may expend up to
0.3125%  quarterly  (approximately  1.25%  annually) of average  daily net asset
value of its shares to pay distribution costs for sales of its shares and to pay
shareholder  service fees. The NASD currently limits such annual expenditures to
1%, of which 0.75% may be used to pay such  distribution  costs and 0.25% may be
used to pay shareholder service fees. The aggregate amount that the Fund may pay
for such  distribution  costs is limited to 6.25% of gross share sales since the
inception of the Fund's  Distribution  Plan plus interest at the prime rate plus
1% on unpaid amounts thereof (less any contingent  deferred sales charge paid by
shareholders to the Principal  Underwriter).  The Fund operates its Distribution
Plan in accordance with both the Distribution Plan and the NASD rules.

         In connection with the  Distribution  Plan, Fund shares are offered for
sale at net asset value without any initial  sales charge,  and the Fund pays or
accrues to the Principal  Underwriter a commission for each sale.  Specifically,
payments  under  the  Distribution  Plan  are  currently  made to the  Principal
Underwriter  (which may reallow  all or part to others  such as dealers)  (1) as
commissions for Fund shares sold and (2) as shareholder  service fees in respect
to shares  maintained  by the  recipients  outstanding  on the Fund's  books for
specified  periods.  Amounts paid or accrued to the Principal  Underwriter under
(1) and (2) in the aggregate may not exceed the annual  limitations  referred to
above.  The  Principal  Underwriter  generally  reallows  to brokers or others a
commission  equal to 3% of the price  paid for each Fund share sold as well as a
shareholder  service  fee at a rate of 0.25% per annum of the net asset value of
shares  maintained by such  recipients  outstanding on the books of the Fund for
specified periods.  Such commissions and service fees are included in the Fund's
operating expenses.

  Beginning  May 1,  1995  until  July  31,  1995  or  until  the  Fund  attains
$50,000,000 in aggregate sales,  whichever occurs first (the "Offering Period"),
the Fund will reopen to new investors. During the Offering Period, the Principal
Underwriter will reallow an increase to those  brokers or others who allow their
individual   selling   representatives  to  participate  in  the  additional  1%
commission.

  In connection with the reopening of the Fund, the maximum annual  expenditures
permitted  under the Fund's  Distribution  Plan have been  temporarily  fixed at
0.65% of the Fund's  average  daily net assets until such time as the  Principal
Underwriter shall have been fully paid all amounts due the Principal Underwriter
that may have arisen during the Offering  Period.  The Fund's Board of Trustees,
in its sole  discretion,  may  increase or  otherwise  modify or  eliminate  the
maximum percentage rate described above.

         If the Fund is unable to pay the Principal  Underwriter a commission on
a  new  sale  because  the  annual  maximum  has  been  reached,  the  Principal
Underwriter intends, but is not obligated,  to continue to accept new orders for
the purchase of Fund shares and to pay  commissions  and service fees to dealers
in excess of the amount it currently  receives from the Fund.  While the Fund is
under no  contractual  obligation  to reimburse the  Principal  Underwriter  for
advances made by the Principal  Underwriter in excess of the  Distribution  Plan
limitation,  the  Principal  Underwriter  intends  to seek full  payment of such
charges  from the Fund  (together  with  interest  at the rate of prime plus one
percent) at such time in the future as, and to the extent that,  payment thereof
by the  Fund  would  be  within  permitted  limits.  The  Principal  Underwriter
currently  intends to seek  payment of  interest  only on such  charges  paid or
accrued  by the  Principal  Underwriter  subsequent  to  July  7,  1992.  If the
Independent  Trustees authorize such payments,  the effect will be to extend the
period of time during which the Fund incurs the maximum  amount of costs allowed
by the Distribution Plan. The Independent Trustees have agreed to cause the Fund
to  reimburse  the  Principal  Underwriter  such  portion of this amount at such
future time when the payment of such amounts  would not cause the Fund to exceed
the Distribution Plan limitation.  If the 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.
    

         The total amounts paid by the Fund under the foregoing arrangements may
not exceed the maximum  Distribution Plan limit specified above, and the amounts
and purposes of expenditures under the Distribution Plan must be reported to the
Fund's Rule 12b-1 Trustees quarterly. The Fund's Rule 12b-1 Trustees may require
or approve changes in the  implementation or operation of the Distribution Plan,
and may also require that total  expenditures by the Fund under the Distribution
Plan be kept  within  limits  lower than the  maximum  amount  permitted  by the
Distribution  Plan as  stated  above.  If such  costs  are  not  limited  by the
Independent Trustees,  such costs could, for some period of time, be higher than
such costs permitted by most other plans presently  adopted by other  investment
companies.

   
         The Distribution Plan may be terminated at any time by vote of the Rule
12b-1 Trustees, or by vote of a majority of the outstanding voting securities of
the Fund. Any change in the Distribution Plan that would materially increase the
distribution expenses of the Fund provided for in the Distribution Plan requires
shareholder  approval.  Otherwise,  the Distribution  Plan may be amended by the
Trustees, including the Fund's Rule 12b-1 Trustees.
    

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

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

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

         Whether any  expenditure  under the  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.  Any  expenditure
subject to such a limit will be included in the Fund's total operating  expenses
for purposes of determining  compliance with the expense 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 state expense
limits.

         Commissions  paid on new sales of shares are treated as capital charges
and deferred sales charges  received by the Fund are treated as capital credits,
respectively, in determining net investment income for tax purposes.

         The Independent  Trustees of the Fund have determined that the sales of
the Fund's shares  resulting  from  payments  under the  Distribution  Plan have
benefited the Fund.


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

   
         Pursuant  to a  Principal  Underwriting  Agreement  (the  "Underwriting
Agreement"),  Keystone  Investment  Distributors  Company  acts  as  the  Fund's
principal  underwriter.  The  Principal  Underwriter,  located  at 200  Berkeley
Street, Boston, Massachusetts 02116-5034, is a Delaware corporation wholly-owned
by Keystone.  The Principal  Underwriter,  as agent,  has agreed to use its best
efforts to find purchasers for the shares. The Principal  Underwriter may retain
and employ  representatives to promote distribution of the shares and may obtain
orders from  brokers,  dealers and others,  acting as  principals,  for sales of
shares  to  them.  The  Underwriting   Agreement  provides  that  the  Principal
Underwriter  will bear the  expense  of  preparing,  printing  and  distributing
advertising and sales literature and prospectuses used by it. In its capacity as
principal  underwriter,  the Principal Underwriter may receive payments from the
Fund pursuant to the Fund's Distribution Plan.

         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.

   
         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.

         For the fiscal  years ended  December  31, 1992 and 1993 the  Principal
Underwriter  earned  commissions of $7,972,003 and $4,969,409 (amount represents
commissions  earned during the fiscal year ended  December 31, 1993 and excludes
recapture by the Principal  Underwriter during said fiscal year of $4,272,087 in
advances  made  during  previous  fiscal  years),  respectively,   after  paying
commissions of $7,260,876 and $3,705,342  (amount  represents sales  commissions
only and excludes  $3,661,327 in maintenance  fees paid during the fiscal year),
respectively,  to retail dealers under the Distribution  Plan. During the fiscal
year  ended  December  31,  1994,  the  Fund  paid  the  Principal   Underwriter
$13,324,192  under the Distribution  Plan. The amount paid by the Fund under its
Distribution Plan, net of deferred sales charges,  was $13,226,327 (0.97% of the
Fund's  average daily net asset value during the period).  During the year,  the
Principal  Underwriter  received $9,126,418 after payments of commissions on new
sales  and  service  fees  to  dealers  and  others  of   $4,197,774.   See  the
"Distribution Plan" section of this document for additional information.

                               TRUSTEES AND OFFICERS
- --------------------------------------------------------------------------------

         The Trustees of the Fund, their principal occupations and some of their
affiliations  over the last  five  years,  and the  Officers  of the Fund are as

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

         The Fund is a Massachusetts business trust originally established under
a  Declaration  of Trust  dated April 12,  1977.  On July 27,  1993,  the Fund's
Declaration of Trust was amended and restated in its entirety (the  "Declaration
of Trust"). The Fund is similar in most respects to a business corporation.  The
principal  distinction  between  the  Fund  and a  corporation  relates  to  the
shareholder liability described below. This summary is qualified in its entirety
by reference to the Declaration of Trust.
    

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 the trust property for any shareholder
held personally liable for the obligations of the Fund.

VOTING RIGHTS

         Under the terms of the  Declaration  of Trust,  shares are  entitled to
vote in the  election of Trustees and on other  matters and no amendment  may be
made to the Declaration of Trust without the approval of the shareholders of the
Fund. 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  less  than  50% of the  shares  will  not be able to  elect  any
Trustees.

LIMITATION OF TRUSTEES' LIABILITY

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


- --------------------------------------------------------------------------------
                              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 each of the funds in the  Keystone  Fund  Family  and to
certain other Keystone Investments Family of Funds.
    

         Except as otherwise noted below,  pursuant to an Investment  Management
Agreement  with  the  Fund  (the  "Management  Agreement")  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 as well as pay all
expenses of Keystone Management incurred in connection with the provision of its
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
shareholders' and Trustees' meetings;  charges and expenses of legal counsel for
the Fund and for the  Trustees  of the Fund on  matters  relating  to the  Fund;
charges and expenses of filing  annual and other  reports with the SEC and other
authorities;  and all extraordinary  charges and expenses of the Fund.  Keystone
Management  pays all charges  and  expenses  relating to these items  subject to
reimbursement by 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.
Keystone Management provides the Fund with certain administrative and management
services,  which  services  include (1)  performing  research and planning  with
respect to (a) the Fund's  qualification as a regulated investment company under
Subchapter  M of the  Internal  Revenue  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; and (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 at the end of each calendar  month a
fee for its services consisting of (1) an amount calculated as set forth below:

ANNUAL                                          AGGREGATE NET
MANAGEMENT                                      ASSET VALUE OF THE
FEE                            INCOME           SHARES 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; and

(2) an amount  equal to  Keystone  Management's  reimbursable  expenses  accrued
during such calendar month.

         As a  continuing  condition  of  registration  of  shares  in a  state,
Keystone  Management  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. However, Keystone Management is not required 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 by the Fund's Board of Trustees or by a vote of a
majority of outstanding  shares on 60 days' written  notice to Keystone,  and by
Keystone on 90 days' written notice to the Fund.  The Management  Agreement will
terminate  automatically  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.

                                   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.  Such
considerations  are judgmental and are weighed by management 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 the Management Agreement with the Fund or
Keystone under the Advisory Agreement with Keystone Management.  The cost, value
and specific  application of such information are  indeterminable  and cannot be
practicably 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's securities transactions are generally principal transactions
with the issuer of the  security  or with major  underwriters  and  dealers  for
municipal  bonds.  Accordingly,  the  Fund  does not pay  significant  brokerage
commissions.  The cost of securities  purchased  from  underwriters  includes an
underwriting  commission or concession  and the prices at which  securities  are
purchased  from and sold to  dealers  include a dealer's  mark-up or  mark-down.
Purchases  from  underwriters  will  include  the  underwriting   commission  or
concession and purchases from dealers  serving as market makers will include the
spread  between the bid and asked  prices.  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.
However,  the Fund's Board of Trustees has determined 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.

   
         For the fiscal years ended  December 31, 1992,  1993 and 1994, the Fund
did not pay any brokerage commissions for securities transactions.

         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.
    


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

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

   
         The  cumulative  total  returns  of the Fund for the one,  five and ten
years ended December 31, 1994 were (9.96)% (including  contingent deferred sales
charge), 30.92% and 124.42%,  respectively. The average annual total returns for
the one, five and ten year periods ended  December 31, 1994 were (9.96)%,  5.54%
and 8.42%, 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 current  yield for the
30-day period ended December 31, 1994 was 5.59%.

         Tax  equivalent  yield is, in general,  the current  yield divided by a
factor  equal to one minus a stated  income  tax rate and  reflects  the yield a
taxable investment would have to achieve in order to equal on an after tax-basis
a tax exempt yield.  The tax equivalent yield for an investor in the 31% federal
tax bracket for the 30-day period ended December 31, 1994 was 8.10%.
    

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

                                MUNICIPAL BONDS

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

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

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

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

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

         From time to time,  proposals have been introduced  before Congress for
the purpose of restricting  or eliminating  the federal income tax exemption for
interest on municipal bonds, and similar proposals may well be introduced in the
future. If such a proposal were enacted, the availability of municipal bonds for
investment by the Fund and the value of the Fund's portfolio could be materially
affected; in which event, the Fund would reevaluate its investment objective and
policies and consider changes in the structure of the Fund or dissolution.

DESCRIPTION OF BOND RATINGS

         The Tax Reform Act of 1986 made significant  changes in the federal tax
status of certain  obligations  that were previously fully federally tax exempt.
As a result,  three categories of such  obligations  issued after August 7, 1986
now exist:  (1) "public purpose" bonds, the income of which remains fully exempt
from federal income tax; (2) qualified "private activity" industrial development
bonds,  the income of which,  while exempt from federal income tax under section
103 of the Internal  Revenue Code of 1954 as amended (Code) is includable in the
calculation of the federal  alternative  minimum tax; and (3) "private activity"
(private  purpose) bonds,  the income of which is not exempt from federal income
tax. The Fund will not invest in private activity  (private purpose) bonds, and,
except as  described  under  "Other  Eligible  Securities,"  will not  invest in
qualified "private activity" industrial development bonds.
    


                      CORPORATE AND MUNICIPAL BOND RATINGS

S&P CORPORATE AND MUNICIPAL BOND RATINGS

A. MUNICIPAL NOTES

         An S&P note rating  reflects the  liquidity  concerns and market access
risks unique to notes.  Notes due in 3 years or less will likely  receive a note
rating.  Notes maturing beyond 3 years will most likely receive a long term debt
rating. The following criteria are used in making that assessment:

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

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

         Note ratings are as follows:

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

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

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

B.  TAX EXEMPT DEMAND BONDS

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

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

C.  CORPORATE AND MUNICIPAL BOND RATINGS

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

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

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

         b.       Nature of and provisions of the obligation; and

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

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

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

Bond ratings are as follows:

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

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

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

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

MOODY'S CORPORATE AND MUNICIPAL BOND RATINGS

         Moody's ratings are as follows:

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

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

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

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

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

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

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


                            MONEY MARKET INSTRUMENTS

         The Fund's  investments in commercial  paper are limited to those rated
A-1 by S&P, Prime-1 by Moody's,  or F-1 by Fitch.  These ratings and other money
market instruments are described as follows:

COMMERCIAL PAPER RATINGS

         Commercial  paper rated A-1 by S&P has the  following  characteristics.
Liquidity ratios are adequate to meet cash requirements.  The issuer's long-term
senior debt is rated "A" or better,  although in some cases "BBB" credits may be
allowed. The issuer has access to at least two additional channels of borrowing.
Basic  earnings  and cash flow  have an upward  trend  with  allowance  made for
unusual circumstances.  Typically, the issuer's industry is well established and
the issuer has a strong position within the industry.
    

         Commercial paper rated A-2 by S&P has the same  characteristics as that
rated A-1 except that the relative degree of safety is not as overwhelming.

         Commercial  paper  rated A-3 has a  satisfactory  capacity  for  timely
payment.  However,  it is somewhat  more  vulnerable  to the adverse  effects of
changes in circumstances than obligations rated A-1 or A-2.

   
         The rating Prime-1 is the highest  commercial  paper rating assigned by
Moody's.  Among the factors  considered by Moody's in assigning  ratings are the
following:  (1)  evaluation  of the  management  of  the  issuer;  (2)  economic
evaluation  of  the  issuer's   industry  or  industries  and  an  appraisal  of
speculative-type risks which may be inherent in certain areas; (3) evaluation of
the issuer's  products in relation to competition and customer  acceptance;  (4)
liquidity;  (5) amount and quality of long-term debt; (6) trend of earnings over
a period of ten  years;  (7)  financial  strength  of a parent  company  and the
relationships  that exist with the issuer; and (8) recognition by the management
of  obligations  that  may be  present  or  may  arise  as a  result  of  public
preparations  to meet such  obligations.  Relative  strength  or weakness of the
above  factors  determines  how the  issuer's  commercial  paper is rated within
various categories.

         Commercial paper rated Prime-2 by Moody's is considered  somewhat lower
than the best commercial paper because margins of protection may not be as large
or because  fluctuations  of protective  elements over the near or  intermediate
term may be of greater amplitude.

UNITED STATES GOVERNMENT SECURITIES

         Securities issued or guaranteed by the United States Government include
a variety of  Treasury  securities  that differ  only in their  interest  rates,
maturities and dates of issuance.  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.
    

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

   
         Some   obligations   of   United   States   Government   agencies   and
instrumentalities,  such as  Treasury  bills and  Government  National  Mortgage
Association ("GNMA") pass-through certificates,  are supported by the full faith
and credit of the United States; others, such as securities of Federal Home Loan
Banks,  by the right of the issuer to borrow from the  Treasury;  still  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 United States  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 that the credit risk with
respect  to  the  instrumentality  does  not  make  its  securities   unsuitable
investments.  United States Government securities will not include international
agencies  or  instrumentalities  in which  the  United  States  Government,  its
agencies or  instrumentalities  participate,  such as the International Bank for
Reconstruction and Development (the "World Bank"), the Asian Development Bank or
the  Inter-American  Development  Bank, or issues insured by the Federal Deposit
Insurance Corporation.
    

CERTIFICATES OF DEPOSITS

         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 United States banks  (including  their branches  abroad) and of
U.S. branches of foreign banks that are members of the Federal Reserve System or
the  Federal  Deposit  Insurance  Corporation,  and have at least $1  billion in
deposits as of the date of their most recently published financial statements.

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

BANKERS' ACCEPTANCES

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


                              OPTIONS TRANSACTIONS

         The Fund may enter into options  transactions.  Any premium paid by the
Fund in  connection  with an option  transaction  may be forfeited if the option
expires unexercised.

         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  purchase  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  purchase  call  options  for the  purpose  of  offsetting
previously  written call options of the same series.  The Fund also may purchase
call options to fix the interest rates of obligations held by it.

         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 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 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 in the transaction.

   
OPTIONS TRADING MARKETS

         Options  that 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.  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 statement of additional
information.

         The staff of the  Securities  and  Exchange  Commission  ("Commission")
currently 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
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 current 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 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 bills 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  able 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 so doing,  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 that are related to
commodity  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 engage in such futures contracts for speculation.

FUTURES CONTRACTS

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

         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 and other
financial  futures  contracts  and sell such  options to  terminate  an existing
position.  Options on currency and other financial futures contracts 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 stock,  currency or other  financial  instruments  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 a currency or other financial
futures  contract 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, the 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 currency and other financial 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  COMMODITY  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 that may be developed  from time to
time and that 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  again 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;  and 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. 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  denominated  in foreign  currencies,
and the Fund temporarily may hold funds in foreign currencies.  Thus, the Fund's
share value 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 CFTC and 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  that 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,
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 in a
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 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
futures  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,  the
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
that may be developed from time to time and that 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 the 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 that are advantageous to the company but disclaim those contracts that
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
payment  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 that 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 recently 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.

</TABLE>

(a) Effective January 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 investment income--net (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 realized capital gains."
For the fiscal years ended December 31, 1992, 1991, and 1990, distributions in
excess of book basis net income were presented as "distribution from paid-in
capital".
(b) Prior to June 30, 1987, net commissions paid on new sales of shares under
the Fund's Rule 12b-1 Distribution Plan had been treated for both financial
statement and tax purposes as capital charges. On June 11, 1987, the
Securities and Exchange Commission adopted a rule which required for financial
statements for the periods ended on or after June 30, 1987, that net
commissions paid under Rule 12b-1 be treated as operating expenses rather than
capital charges. Accordingly, beginning with the year ended December 31, 1987,
the Fund's financial statements reflect 12b-1 Distribution Plan expenses
(i.e., shareholder servicing fees plus commissions paid net of deferred sales
charges received by the Fund) as a component of net investment income.
(c) Excluding contingent deferred sales charges.
(d) Calculation based on average shares outstanding.

Keystone Tax Free Fund
NOTES TO FINANCIAL STATEMENTS
1. Significant Accounting Policies

Keystone Tax Free 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 is
registered under the Investment Company Act of 1940 as a diversified open-end
investment company.

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. 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. Tax-exempt bonds are stated on the basis of valuations provided by a
pricing service, approved by the Board of Trustees, that uses information with
respect to transactions in bonds, quotations from bond dealers, market
transactions in comparable securities and various relationships between
securities in determining value. Non- tax-exempt securities for which market
quotations are readily available are valued at the price quoted which, in the
opinion of the Board of Trustees or their representative, most nearly
represents their market value.

Short-term investments which are purchased with maturities of sixty days or
less are valued at amortized cost (original purchase cost as adjusted for
amortization of premium or accretion of discount) which when combined with
accrued interest approximates market. Short- term investments maturing in more
than sixty days for which market quotations are readily available are valued
at current market value. Short-term investments maturing in more than sixty
days when purchased which are held on the sixtieth day prior to maturity are
valued at amortized cost (market value on the sixtieth day adjusted for
amortization of premium or accretion of discount) which when combined with
accrued interest approximates market. All other securities and other assets
are valued at fair value as determined in good faith using methods prescribed
by the Board of Trustees.

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

C. Securities transactions are accounted for on the trade date. Realized gains
and losses are recorded on the identified cost basis. Interest income is
recorded on the accrual basis. All premiums and original issue discounts are
amortized/accreted for both financial reporting and federal income tax
purposes.

D. 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 expects to

<PAGE>
be relieved of any federal income tax liability by distributing all of its tax
basis income and net 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.

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 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 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.  The Fund distributes net investment income to shareholders monthly and net
capital gains, if any, annually. Distributions from net investment income are
determined in accordance with income tax regulations. Dividends from net
investment income can exceed the Fund's book basis net investment income.
Effective January 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, the Fund changed the financial statement classification of
distributions to shareholders to better disclose the differences between
financial statement amounts available for distribution and amounts distributed
to comply with income tax regulations. The significant difference between
financial statement amounts available for distribution and distributions made
in accordance with income tax regulations is due to the difference in the
treatment of 12b-1 Distribution Plan charges.
2. Capital Share Transactions

The Declaration of Trust authorizes the issuance of an unlimited number of
shares of beneficial interest with no par value. Transactions in shares of the
Fund were as follows:

<PAGE>

                                     Year Ended December 31,
                                    1994                1993
Shares sold                       16,871,171          20,470,708
Shares redeemed                  (43,806,889)        (20,802,266)
Shares issued in
  reinvestment of:
  Distributions from
  investment income-- net
  and Distributions in
  excess of investment
  income--net                      5,031,307           5,196,577
Distributions from
  realized gains--net                      0           5,110,384
Net increase                     (21,904,411)          9,975,403

 The Fund bears some of the costs of selling its shares under a Distribution
Plan adopted pursuant to Rule 12b-1 under the Investment Company Act of 1940.
The Distribution Plan provides that the Fund may incur certain expenses which
may not exceed a maximum amount equal to 0.3125% of the Fund's average daily
net assets for any quarter occurring after the inception of the Distribution
Plan. Under the Distribution Plan, the Fund pays Keystone Distributors, Inc.
("KDI"), the principal underwriter and a wholly- owned subsidiary of Keystone,
amounts which in total may not exceed the Distribution Plan maximum.

In connection with the Distribution Plan and subject to the limitations
discussed below, Fund shares are offered for sale at net asset value without
any initial sales charge. From the amounts received by KDI in connection with
the Distribution Plan, and subject to the limitations discussed below, KDI
generally pays brokers or others a commission equal to 3% of the price paid to
the Fund for each sale of Fund shares as well as a shareholder service fee at
a rate of 0.25% per annum of the net asset value of the shares sold by such
brokers or others and remaining outstanding on the books of the Fund for
specified periods.

To the extent Fund shares purchased prior to July 8, 1992 are redeemed within
four calendar years of original issuance, the Fund may be eligible to receive
a deferred sales charge from the investor as partial reimbursement for sales
commissions previously paid on those shares. This charge is based on declining
rates, which begin at 4.0%, applied to the lesser of the net asset value of
shares redeemed or the total cost of such shares.

Since July 8, 1992, contingent deferred sales charges applicable to shares of
the fund issued after January 1, 1992 have, to the extent permitted by the
NASD Rule, been paid to KDI rather than to the Fund. During the fiscal year
ended December 31, 1994, KDI received $745,076 in contingent deferred sales
charges.

A rule of the National Association of Securities Dealers, Inc. ("NASD Rule")
limits the annual expenditures, which the Fund may incur under the
Distribution Plan to 1%, of which 0.75% may be used to pay such distribution
expenses and 0.25% may be used to pay shareholder service fees. The NASD Rule
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 Fund's 12b-1
Distribution Plan, plus interest at the prime rate plus 1% on unpaid amounts
thereof (less any contingent deferred sales charges paid by the shareholders
to KDI).

KDI intends, but is not obligated, to continue to pay or accrue distribution
charges which exceed current annual payments permitted to be received by KDI
from the Fund. KDI intends to seek full pay

<PAGE>
ment 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 permitted limits. KDI
currently intends to seek payment of interest only on such charges paid or
accrued by KDI subsequent to January 1, 1992.

During the year ended December 31, 1994, the Fund recovered $97,865 in
contingent deferred sales charges. During the year, the Fund paid KDI
$13,324,192 under the Distribution Plan. The amount paid by the Fund under its
Distribution Plan, net of deferred sales charge, was $13,226,327 (0.97% of the
Fund's average daily net assets). During the year, KDI received $9,126,418,
after payments of commissions on new sales and service fees to dealers and
others of $4,197,774.
3. Securities Transactions

As of December 31, 1994, the Fund had a capital loss carryover for Federal tax
purposes of approximately $25,307,000 which expires in 2002. Additionally, the
Fund has incurred capital losses of approximately $11,617,000 in the current
fiscal year which, under the Tax Reform Act of 1986 are treated for tax
purposes as occurring on the first day of the Fund's next fiscal year and are
available as an offset to capital gains that may be recognized in the next
fiscal year.

For the year ended December 31, 1994, purchases and sales of investment
securities 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, as well as certain additional operating
services, facilities and supplies. In return, KMI is paid monthly, (i) a
management fee calculated daily at a rate of 2.0% of the Fund's gross
investment income plus an amount determined by applying percentage rates
starting at 0.50% and declining as net assets increase, to 0.25% per annum, to
the net asset value of the Fund, and (ii) an amount equal to KMI's
reimbursable expenses accrued during the year in providing such additional
services. 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 December 31, 1994, the Fund paid or accrued to KMI
investment management and administrative services fees of $7,970,545. Included
in this amount is the management fee of $5,941,545, which represented 0.43% of
the Fund's average net assets. Of such management fee paid to KMI, $5,050,313
was paid to Keystone for its services to the Fund.

Also included in the total investment management and administrative services
fee paid by the Fund were the following approximate amounts incurred by KMI
(and reimbursed by the Fund) in providing or obtaining for the Fund the
additional operating services, facilities and supplies required by the
Agreement: transfer agent fee, $1,418,400; audit and legal fees,

$86,200; custodian fees, $264,100; printing and supplies, $43,100;
registration fees, $106,450; and other, $110,750.

During the year ended December 31, 1994, the Fund paid or accrued to KGI
$23,917 for certain accounting services and to KIRC $1,418,000 for transfer
agent fees. This amount for transfer agent fees is included in the payments
made by KMI described in the preceding paragraph.
5. Distributions to Shareholders

The net investment income of the Fund (interest income accrued as earned, less
expenses of the Fund) is determined as of the normal close of trading on the
New York Stock Exchange each business day on which the exchange is open. The
net investment income so determined each day is declared as a dividend to
shareholders of record at the time of such determination and is distributed
promptly after the end of each calendar month. Any net realized short-term and
long- term capital gains in excess of carried-over losses, will be distributed
annually. All distributions of net investment income will be paid in cash
unless the shareholder has directed that they be reinvested, in which case
such reinvestment will be at the net asset value on the last business day of
the month in which declared. Any distributions of capital gains will be
reinvested in additional shares of the Fund at net asset value on the record
date of the month in which declared unless the shareholder has specified that
they wish to receive cash. Shares acquired through reinvestment of net
investment income or capital gains are not subject to contingent deferred
sales charges.

INDEPENDENT AUDITORS' REPORT
The Trustees and Shareholders
Keystone Tax Free Fund

We have audited the accompanying statement of assets and liabilities of
Keystone Tax Free Fund, including the schedule of investments, as of December
31, 1994, and the related statement of operations for the year then ended, the
statements of changes in net assets for each of the years in the two-year
period then ended and the financial highlights for each of the years in the
ten-year period then ended. 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
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements and
financial highlights are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. Our procedures included confirmation of securities
owned as of December 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.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Keystone Tax Free Fund, as of December 31, 1994, the results of its operations
for the year then ended, the changes in its net assets for each of the years
in the two-year period then ended, and the financial highlights for each of
the years in the ten-year period then ended in conformity with generally
accepted accounting principles.

                  CALCULATION OF FEDERAL TAX EQUIVALENT YIELD

Fund:   Keystone Tax Free Fund

Calculation Period:                 30 days ended December 31, 1994

Yield:            5.59%

         The Keystone Tax Free Fund intends to advertise  tax  equivalent  yield
based on the yield of the Fund over a 30-day period.  The  calculation  includes
the tax equivalent yield from an investment which is exempt from federal taxes.

Calculation below assumes:

                           Joint return, 31% tax bracket

Method:

         Subtract federal rate from 1 and divide yield by the result:

                                    1.00
                                    0.31
                                    ----
                                    0.69

         30 day yield   5.59% = 8.10% Federal Tax Equivalent Yield
                        -----
                        0.69
