  Keystone  Custodian Fund,  Series B-4 (the "Fund") is a mutual fund whose goal
is generous  income.  The Fund invests  primarily in  corporate  bonds,  and its
portfolio  ordinarily  includes a substantial  number of bonds that, as a class,
sell at  discounts  from par value.  The generous  income  sought by the Fund is
ordinarily associated with high yield, high risk bonds and similar securities in
the lower rating categories of the recognized rating agencies or with securities
that are unrated.

  Your purchase payment is fully invested. There is no sales charge when you buy
the Fund's shares. The Fund may impose,  however, 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 November 30, 1994,  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.

  THE FUND MAY INVEST UP TO 100% OF ITS ASSETS IN LOWER  RATED  BONDS,  COMMONLY
KNOWN AS "JUNK BONDS," WHICH ENTAIL  GREATER  RISKS,  INCLUDING  DEFAULT  RISKS,
UNTIMELY INTEREST AND PRINCIPAL PAYMENTS AND PRICE VOLATILITY,  THAN THOSE FOUND
IN HIGHER RATED SECURITIES, AND MAY PRESENT PROBLEMS OF LIQUIDITY AND VALUATION.
INVESTORS  SHOULD  CAREFULLY  CONSIDER THESE RISKS BEFORE  INVESTING.  SEE "FUND
OBJECTIVE AND POLICIES," PAGE 4; "RISK FACTORS," PAGE 5.

<F1>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 July 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.
<F2>Effective August 1, 1993, the Fund adopted Statement of Position 93-2:  ``Determination,  Disclosure,  and Financial  Statement

    amounts  exceeding  book basis  investment  income  ~=m 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 net realized  ~capital
    gains.'' From January 31, 1990 until the date of adoption of the Statement of Position,  distribution  amounts  exceeding  book
    basis investment ~income -- net were charged to paid-in capital.

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

  The Fund is an open-end,  diversified management investment company,  commonly
known as a mutual fund. The Fund was created under  Pennsylvania law as a common
law trust and has been  offering its shares  continuously  since  September  11,
1935.  The Fund is one of twenty  funds  managed by  Keystone  Management,  Inc.
("Keystone Management"), the Fund's investment manager, and is one of thirty-one
funds managed or advised by Keystone  Custodian Funds,  Inc.  ("Keystone"),  the
Fund's investment  adviser.  Keystone and Keystone  Management are, from time to
time, collectively referred to as "Keystone."

- ------------------------------------------------------------------------------
FUND OBJECTIVE AND POLICIES
- ------------------------------------------------------------------------------

  The Fund's  investment  objective  is to provide  shareholders  with  generous
income. To achieve this objective the Fund invests primarily in corporate bonds,
and its portfolio ordinarily includes a substantial number of bonds, which, as a
class,  sell at  discounts  from par value and are  rated by  Standard  & Poor's
Corporation  ("S&P") or Moody's  Investors  Service,  Inc.  ("Moody's") as below
investment  grade,  i.e., S&P rating below BBB and Moody's rating below Baa. The
Fund may purchase securities with any rating or may purchase unrated securities,
which are not necessarily of lower quality than rated securities, but may not be
as attractive to as many buyers. While Keystone performs its own credit analyses
of the  Fund's  investments  and does not rely on  ratings  assigned  by  rating
services,   bonds  rated  below  investment  grade  generally   involve  greater
volatility  of price and risk of  principal  and income than bonds in the higher
rating categories and are, on balance,  considered predominantly speculative. In
addition  to its  other  investment  options,  the Fund may  invest  in  limited
partnerships, including master limited partnerships, and may invest up to 25% of
its assets in foreign securities.  The Fund may also invest in participations in
bank loans.

  When market  conditions  warrant,  the Fund may adopt a defensive  position to
preserve  shareholders'  capital by investing in money market instruments.  Such
instruments,  which must mature  within one year of their  purchase,  consist of
United   States   ("U.S.")   government   securities;   instruments,   including
certificates of deposit,  demand and time deposits and bankers' acceptances,  of
banks which are members of the Federal  Deposit  Insurance  Corporation and have
assets of at least $1 billion,  including  U.S.  branches  of foreign  banks and
foreign branches of U.S. banks; prime commercial paper,  including master demand
notes; and repurchase agreements secured by U.S. government securities.

  The Fund's  investments  may  include  fixed and  adjustable  rate or stripped
bonds,  including  zero coupon bonds and  payment-in-kind  securities  ("PIKs"),
debentures, notes, equipment trust certificates,  U.S. government securities and
debt securities  convertible into or exchangeable for preferred or common stock.
The Fund may continue to hold  preferred or common stock  received in connection
with convertible or exchangeable  securities.  The Fund may also invest in units
consisting  of debt  securities  with stock or warrants  to buy stock  attached.
Under ordinary circumstances, at least 65% of the Fund's assets will be invested
in bonds and debentures.

  The Fund may also invest in preferred stock,  including  convertible preferred
stock and adjustable rate preferred stock, warrants, which may be used to create
other permissible  investments,  and common stock of issuers that are objects of
acquisition  attempts,  are  undergoing  reorganization  through  bankruptcy  or
otherwise, or are in the process of refinancing. Investments in common stocks of
such  issuers are expected to provide the Fund with the  opportunity  to receive
high-yielding,  fixed-income  securities.  Investments  in common stocks will be
limited to those stocks that Keystone believes will assist the Fund in achieving
its investment objective.

  The Fund may write  covered call and put options.  The Fund may also  purchase
call and put  options,  including  call and put  options  to close out  existing
positions,  and employ new investment  techniques  with respect to such options.
The Fund  currently  does not  intend  to invest  more than 5% of its  assets in
options transactions.

  The Fund may enter into reverse repurchase  agreements and firm commitment and
when-issued  transactions for securities and currencies.  In addition,  the Fund
may enter into  currency and other  financial  futures  contracts  and engage in
related options  transactions  for hedging  purposes and not for speculation and
may employ new investment  techniques with respect to such futures contracts and
related options transactions.

  In addition to the options,  futures  contracts and forwards  mentioned above,
the Fund may also  invest in  certain  other  types of  derivative  instruments,
including  collateralized mortgage obligations,  structured notes, interest rate
swaps, index swaps, currency swaps and caps and floors. These basic vehicles can
also be combined to create more complex  products  called hybrid  derivatives or
structured securities.

  Investments in foreign securities,  options  transactions and other complex or
derivative  securities involve certain risks. For an explanation of these risks,
see the section of this prospectus entitled "Additional Investment  Information"
and the statement of additional  information.  For further information generally
about the types of investments and investment  techniques  available to the Fund
and the  associated  risks,  see  "Additional  Investment  Information"  and the
statement of additional information.

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

  Of course, there can be no assurance that the Fund will achieve its investment
objective  since  there is  uncertainty  in  every  investment.  The  investment
objective  of the Fund  cannot be  changed  without a vote of the  holders  of a
majority (as defined in the 1940 Act) of the Fund's outstanding shares.

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

  Since 1935, the Fund has had continuous  experience investing in bonds selling
at a substantial discount from par, convertible bonds, noninvestment grade bonds
and other  securities  that as a class may be considered  high yield,  high risk
securities.  Prior to the  1980's,  corporate  bonds  were  primarily  issued to
finance growth and  development.  Noninvestment  grade bonds were  predominantly
bonds that often  traded at  discounts  from par  because the  company's  credit
ratings had been downgraded.  The rapid growth of the noninvestment grade sector
of the bond market during the 1980's was largely attributable to the issuance of
such bonds to finance  corporate  reorganizations.  An economic  downturn  could
severely disrupt the market for high yield, high risk bonds and adversely affect
the value of outstanding bonds and the ability of issuers to repay principal and
interest.  Although the change in the size and characteristics of the market may
result in higher risks associated with individual bonds,  Keystone believes that
an effective program of broad  diversification  can over time enable the Fund to
successfully  achieve  its  investment  objective  while  reducing  the  risk of
investing in individual noninvestment grade bonds.

  The Fund seeks to maximize  investment  return to its  shareholders  over time
from a combination  of many factors,  including  high current income and capital
appreciation  from high yielding,  high risk bonds and other similar  securities
commonly  referred to as "junk bonds."  Realizing this objective  involves risks
that are greater than the risks of investing in higher  quality debt  securities
and may result in greater  upward and downward  movements in the net asset value
per share of the Fund. These risks should be carefully  considered by investors.
These  risks are  discussed  in  greater  detail  below and  include  risks from
interest rate fluctuations;  changes in credit status,  including weaker overall
credit condition of issuers and risks of default;  industry, market and economic
risk; volatility of price resulting from broad and rapid changes in the value of
underlying securities; and greater price variability and credit risks of certain
high yield, high risk securities such as zero coupon bonds and PIKs.

  While  investment in the Fund provides  opportunities  to maximize return over
time,  investors  should  be  aware  of  the  following  risks  associated  with
noninvestment grade bonds:

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

  (2) The lower ratings of certain securities held by the Fund reflect a greater
possibility that adverse changes in the financial  condition of the issuer or in
general economic conditions, or both, or an unanticipated rise in interest rates
may impair the ability of the issuer to make payments of interest and principal,
especially if the issuer is highly leveraged.  Such issuer's ability to meet its
debt  obligations  may  also  be  adversely   affected  by  specific   corporate
developments,  the  issuer's  inability  to  meet  specific  projected  business
forecasts,  or the  unavailability  of additional  financing.  Also, an economic
downturn or an increase in interest rates may increase the potential for default
by the issuers of these securities.

  (3) The value of certain  securities held by the Fund may be more  susceptible
to real or  perceived  adverse  economic,  company or  industry  conditions  and
publicity than is the case for higher quality securities.

  (4) The  values  of  certain  securities,  like  those of other  fixed  income
securities,  fluctuate in response to changes in interest  rates.  When interest
rates  decline,  the value of a  portfolio  invested in bonds can be expected to
rise. Conversely, when interest rates rise, the value of a portfolio invested in
bonds can be expected to decline. For example, in the case of an investment in a
fixed-income  security,  if  interest  rates  increase  after  the  security  is
purchased,  the  security,  if sold prior to maturity,  may return less than its
cost.  The prices of  noninvestment  grade bonds,  however,  are generally  less
sensitive  to  interest  rate  changes  than the prices of  higher-rated  bonds;
noninvestment  grade bonds are more  sensitive  to adverse or positive  economic
changes or individual corporate developments.

  (5) The secondary  market for certain  securities held by the Fund may be less
liquid at certain  times than the  secondary  market  for  higher  quality  debt
securities,  which may have an  adverse  effect on market  price and the  Fund's
ability to dispose of particular  issues and may also make it more difficult for
the Fund to obtain  accurate  market  quotations  for  purposes  of valuing  its
assets.

  (6) Zero coupon bonds and PIKs involve additional special considerations. Zero
coupon bonds do not require the periodic payment of interest. PIK bonds are debt
obligations  that  provide  that the issuer may, at its option,  pay interest on
such  bonds  in  cash  or in the  form  of  additional  debt  obligations.  Such
investments  may  experience  greater  fluctuation  in value due to  changes  in
interest rates than debt  obligations that pay interest  currently.  Even though
these  investments do not pay current  interest in cash, the Fund is nonetheless
required  by tax laws to  accrue  interest  income  on such  investments  and to
distribute such amounts at least annually to shareholders.  Thus, the Fund could
be required at times to liquidate  investments in order to fulfill its intention
to distribute substantially all of its net income as dividends.

  The  generous  income  sought  by  the  Fund  is  ordinarily  associated  with
securities in the lower rating  categories of the recognized  rating agencies or
with  securities  that are unrated.  Such  securities are generally  rated BB or
lower by S&P or Ba or lower by Moody's.  The Fund may invest in securities  that
are rated as low as D by S&P and C- by Moody's.  It is possible  for  securities
rated D or C-,  respectively,  to have defaulted on payments of principal and/or
interest  at the time of  investment.  The section of this  prospectus  entitled
"Additional Investment Information" describes these rating categories.  The Fund
intends to invest in D rated debt only in cases when,  in  Keystone's  judgment,
there is a distinct prospect of improvement in the issuer's  financial  position
as a result of the completion of reorganization or otherwise.  The Fund may also
invest in unrated  securities  that, in Keystone's  judgment,  offer  comparable
yields  and  risks  to  those  of  securities  that  are  rated,  as  well as in
non-investment quality zero coupon bonds or PIKs.

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

  The  following  table shows the  weighted  average  percentages  of the Fund's
assets  invested  at the  end of each  month  during  the  last  fiscal  year in
securities  assigned  to the  various  rating  categories  by S&P and in unrated
securities  determined  by  Keystone  to be of  comparable  quality.  Since  the
percentages in this table are based on month-end averages  throughout the Fund's
fiscal year,  they do not reflect the Fund's  holdings at any one point in time.
The  percentages  in each  category may be higher or lower on any day than those
shown in the table.

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

  Income and yields on high yield,  high risk securities,  as on all securities,
will fluctuate over time.

  The Fund may invest in restricted  securities,  including  securities eligible
for resale  pursuant  to Rule 144A under the  Securities  Act of 1933 (the "1933
Act").  Generally,  Rule 144A  establishes  a safe harbor from the  registration
requirements  of the 1933 Act for resales by large  institutional  investors  of
securities  not  publicly  traded in the U.S.  The Fund may  purchase  Rule 144A
securities when such securities present an attractive investment opportunity and
otherwise meet the Fund's selection criteria.  The Board of Trustees has adopted
guidelines  and  procedures  pursuant to which the  liquidity of the Fund's Rule
144A  securities is  determined  by Keystone and the Board of Trustees  monitors
Keystone's implementation of such guidelines and procedures.

  At the present time, the Fund cannot accurately predict exactly how the market
for Rule 144A  securities  will  develop.  A Rule 144A security that was readily
marketable upon purchase may subsequently become illiquid. In such an event, the
Board of Trustees will consider what action, if any, is appropriate.

  With respect to derivative or structured securities,  the market value of such
securities may vary depending on the manner in which such  securities  have been
structured.  As a result,  the value of such  investments  may  change at a more
rapid rate than that of traditional fixed income securities.

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

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

  Generally,  the Fund may not do the following:  (1) invest more than 5% of its
assets,  computed at market value at the time of purchase,  in the securities of
any one issuer (other than U.S. government securities) except that not more than
25% of its assets  may be  invested  without  regard to this  limit;  (2) borrow
money,  except  that the Fund may  borrow  money  from  banks for  temporary  or
emergency purposes in aggregate amounts up to 10% of the value of the Fund's net
assets  (computed at cost) or enter into  reverse  repurchase  agreements  (bank
borrowings and reverse repurchase agreements, in aggregate, shall not exceed 10%
of the value of the Fund's  net  assets);  and (3)  invest  more than 25% of its
assets in securities of issuers in the same industry.

  Although not fundamental  restrictions  or policies  requiring a shareholders'
vote to change, the Fund has undertaken to a state securities authority that, so
long as the state  authority  requires and shares of the Fund are registered for
sale in that  state,  the Fund will (1) limit its  purchase of warrants to 5% of
net assets,  of which 2% may be warrants  not listed on the New York or American
Stock Exchange; (2) not invest in real estate limited partnership interests; and
(3) not invest in oil, gas or other mineral leases.

  In 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.

- ------------------------------------------------------------------------------
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 is  currently
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  the  money  market  instruments  it  purchases  as  follows:
short-term money market  instruments  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; money market instruments maturing in more
than sixty days for which market  quotations are readily available are valued at
current market value; and money market  instruments  maturing in more than sixty
days when purchased,  which are held on the sixtieth day prior to maturity,  are
valued  at  amortized  cost  (market  value on the  sixtieth  day  adjusted  for
amortization  of premium or accretion of  discount),  which,  when combined with
accrued interest,  approximates  market and, in any case, reflects fair value as
determined by the Board of Trustees.  All other investments are valued at market
value or, where market  quotations are not readily  available,  at fair value as
determined in good faith by the Board of Trustees.

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

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

  The Fund has  qualified  and  intends to qualify in the future as a  regulated
investment company under the Internal Revenue Code. The 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  when  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 such distributions  would
be (1) declared in October,  November,  or December to shareholders of record in
such month,  (2) paid by the  following  January 31, and (3)  includable  in the
taxable income of the shareholder 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.  The Fund will make  distributions
from its net  investment  income to its  shareholders  by the 15th day of March,
June,  September and December each year and net capital gains,  if any, at least
annually.

  Currently,  commissions  paid by the Fund on new  sales of  shares  under  the
Fund's  Distribution  Plan (see  "Distribution  Plan") and deferred sales charge
receipts are treated as capital charges and capital  credits,  respectively,  in
determining  net  investment  income for tax purposes.  For financial  statement
purposes, however, these expenses and receipts are treated as operating expenses
and expense offsets. As a result, the amount of dividend  distributions required
to satisfy  the  requirements  of the  Internal  Revenue  Code might  exceed net
investment income for financial  statement  purposes,  resulting in a portion of
such  dividends  being a  distribution  in excess of net  investment  income for
financial  statement  purposes.  Total investment  return is equally affected by
both treatments.  Recently, the Internal Revenue Service ("IRS") issued a ruling
that will require the Fund,  effective April 1, 1995, to treat its 12b-1 fees as
operating  expenses,  instead of as capital  charges.  The Fund intends to be in
compliance  with the IRS ruling by that date. As a result,  after April 1, 1995,
dividend  distributions  are no longer expected to exceed net investment  income
for financial statement purposes. Total investment return will not be affected.

  The Fund  makes  distributions  in  additional  shares  of the Fund or, at the
shareholder's  election  (which  must be made  before  the  record  date for the
distribution),  in cash. Income dividends and net short-term gains distributions
are taxable as ordinary  income and net  long-term  gains are taxable as capital
gains regardless of how long the shareholder has held the Fund's shares. If Fund
shares held for less than six months are sold at a loss, however, such loss will
be treated for tax  purposes as a  long-term  capital  loss to the extent of any
long-term capital gains dividends received. Dividends and distributions also may
be subject to state and local taxes. The Fund advises its shareholders  annually
as to the federal tax status of all distributions made during the year.

provides  accounting,   bookkeeping,  legal,  personnel  and  general  corporate
services to Keystone  Management,  Keystone,  their  affiliates and the Keystone
Group 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 its Investment Management Agreement with the Fund.

  During  the year  ended July 31,  1994,  the Fund paid or accrued to  Keystone
Management investment management and administrative services fees of $4,829,247,
which represented 0.52% of the Fund's average net assets. Of such amount paid to
Keystone  Management,  $4,104,859 was paid to Keystone for  investment  advisory
services to the Fund.

  Keystone   Management  and  Keystone  have  each  adopted  a  Code  of  Ethics
incorporating  policies on personal  securities  trading as  recommended  by the
Investment  Company Institute  ("ICI"),  and it is anticipated that the Board of
Trustees of the Fund will adopt a Code of Ethics  containing the ICI recommended
policies at its next Board meeting to be held in December, 1994.

FUND EXPENSES
  In addition to the investment  advisory and management  fees discussed  above,
the principal expenses 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 July 31,  1994,  the Fund paid  1.84% of its  average  net assets in
expenses.

  During  the  fiscal  year  ended  July 31,  1994,  the Fund paid or accrued to
Keystone  Investor  Resource  Center,  Inc.  ("KIRC"),  the Fund's  transfer and
dividend  disbursing  agent,  and Keystone Group $20,922 for certain  accounting
services  and  $2,391,954  for  transfer  agent  fees.  KIRC  is a  wholly-owned

  The Fund's  portfolio  turnover rates for the fiscal years ended July 31, 1993
and 1994 were 125% and 110%,  respectively.  High portfolio turnover may involve
correspondingly greater brokerage commissions and other transaction costs, which
would be borne directly by the Fund, as well as additional realized gains and/or
losses  to   shareholders.   For  further   information   about   brokerage  and
distributions, see the statement of additional information.

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

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

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

  The  Fund's  shares are sold at the net asset  value per share  next  computed
after it receives  the purchase  order.  The initial  purchase  must be at least
$1,000  except for purchases by  participants  in certain  retirement  plans for
which the  minimum is  waived.  There is no minimum  for  subsequent  purchases.
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 same 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. If
imposed,  the  contingent  deferred sales charge is deducted from the redemption
proceeds  otherwise payable to you. Prior to July 8, 1992, the Fund retained the
deferred   sales  charge.   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 the NASD,  paid to KDI. For the
fiscal year ended July 31, 1994, the Fund  recovered  $179,947 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 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 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.

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

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 contingent
deferred sales charge 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 KDI; and (3) a
bank or trust company acting as a trustee for a single account.

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

  The Fund bears some of the costs of selling its shares under its  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 the 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  services 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 KDI).

  Payments  under the  Distribution  Plan are  currently  made to KDI (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 of shares maintained
by the recipients outstanding on the Fund's books for specified periods. Amounts
paid or  accrued  to KDI under (1) and (2) in the  aggregate  may not exceed the
annual limitation referred to above. KDI generally reallows to brokers or others
a commission equal to 4% 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.

  If the Fund is unable to pay KDI a commission on a new sale because the annual
maximum (0.75% of average daily net assets) has been reached,  KDI 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 in excess of the amount
it  currently  receives  from the Fund.  While the Fund is under no  contractual
obligation to pay KDI such amounts that exceed the Distribution Plan limitation,
KDI 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.  KDI currently  intends to seek payment of interest only on such charges
paid or accrued by KDI  subsequent  to July 7, 1992.  If the Fund's  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. If the  Distribution  Plan is  terminated,  KDI will ask the
Independent  Trustees to take whatever  action they deem  appropriate  under the
circumstances with respect to payment of such amounts.

  During the year ended July 31, 1994, the Fund recovered $179,947 in contingent
deferred sales charges.  During the year, the Fund paid KDI $9,079,585 under the
Distribution  Plan. The amount paid by the Fund under its Distribution Plan, net
of  contingent  deferred  sales  charges,  was  $8,899,638  (0.96% of the Fund's
average  daily net asset  value).  For the year ended July 31, 1994,  KDI earned
$4,485,981  in  commissions  and  service  fees,  of which  amount KDI  actually
received  $2,334,230 after payments of commissions on new sales and service fees
to  dealers  and  others  of  $6,745,355.  During  the year,  KDI also  received
$1,014,043 in contingent  deferred sales charges.  At July 31, 1994, KDI's total
unreimbursed  12b-1 expenses amounted to $10,565,436  (1.38% of net assets as of
July 31,  1994).  The right to  certain  portions  of this  amount,  if and when
receivable,  was  assigned  by KDI  in  1988  in  connection  with  a  financial
transaction.  As of July 31, 1994,  $7,396,647 of the amount  assigned  remained
outstanding.

  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 Rule
12b-1 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,  KDI, at its own expense,  may  periodically
sponsor programs that 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   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 Fund's  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.  The  Fund  may  impose  a  deferred  sales  charge  at the  time of
redemption  of certain  shares as  explained in "How to Buy Shares." If imposed,
the  Fund  deducts  the  deferred  sales  charge  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 will mail the redemption
proceeds upon clearance of the purchase  check,  which may take up to 15 days or
more.  Any delay may be avoided by  purchasing  shares  either  with a certified
check or by bank wire of funds.  Although the mailing of a redemption  check 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 check has been delayed,  the check will be mailed 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.

  Shareholders also may redeem their shares through their  broker-dealers.  KDI,
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.  KDI
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.  KDI 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 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.

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

  If the redemption proceeds are less than $2,500, they will be mailed by check.
If they are $2,500 or more,  they will be  mailed,  wired or sent by EFT to your
previously  designated bank account as you direct. If you do not specify how you
wish your  redemption  proceeds to be sent, they will be mailed by check. If you
cannot  reach the Fund by  telephone,  you  should  follow  the  procedures  for
redeeming by mail or through a broker as set forth above.


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

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

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

- ------------------------------------------------------------------------------
SHAREHOLDER SERVICES
- ------------------------------------------------------------------------------

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

KEYSTONE AUTOMATED RESPONSE LINE
  The Keystone Automated Response Line offers shareholders specific fund account
information  and price and yield  quotations  as well as the  ability  to effect
account  transactions,   including   investments,   exchanges  and  redemptions.
Shareholders  may  access  KARL  by  dialing  toll  free  1-800-346-3858  on any
touch-tone telephone, 24 hours a day, seven days a week.

EXCHANGES
  A shareholder who has obtained the appropriate  prospectus may exchange shares
of the Fund for  shares  of any of the other  seven  Keystone  Custodian  Funds,
Keystone Precious Metals Holdings,  Inc. ("KPMH"),  Keystone  International Fund
Inc.  ("KIF"),  Keystone  Tax Free Fund  ("KTFF"),  Keystone  Tax  Exempt  Trust
("KTET") or Keystone  Liquid Trust ("KLT") on the basis of their  respective net
asset values by calling toll free 1-800-343-2898 or by writing KIRC at Box 2121,
Boston,  Massachusetts  02106-2121.  Fund  shares  purchased  by  check  may  be
exchanged for shares of the named funds, other than KPMH, KTET or KTFF, after 15
days provided  good payment for the purchase of Fund shares has been  collected.
In order to exchange Fund shares for shares of KPMH, KTET or KTFF, a shareholder
must have  held Fund  shares  for a period of at least six  months.  There is no
exchange fee for  exchanges  initiated by an individual  investor  through KARL;
other  exchanges  made by phone are subject to a $10 exchange fee. 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
to terminate this exchange offer or to change its terms,  including the right to
change the service charge 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. 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. 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.

RETIREMENT PLANS
  The Fund has various pension and profit-sharing  plans available to investors,
including  Individual  Retirement Accounts ("IRAs");  Rollover IRAs;  Simplified
Employee Pension Plans ("SEPs");  Tax Sheltered  Annuity Plans ("TSAs");  401(k)
Plans; Keogh Plans;  Corporate  Profit-Sharing Plans; Pension and Target Benefit
Plans;  Money Purchase  Pension Plans and  Salary-Reduction  Plans. For details,
including fees and application  forms,  call KIRC toll free at 1-800-247-4075 or
write to KIRC at P.O. Box 2121, Boston, Massachusetts 02106- 2121.

AUTOMATIC INVESTMENT PLAN
  Shareholders  may  take  advantage  of  investing  on an  automatic  basis  by
establishing an automatic  investment  plan.  Funds are drawn on a shareholder's
checking account monthly and used to purchase Fund shares.

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" and "current  yield."
BOTH 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.

  The Fund may include  comparative  performance  information  in advertising or
marketing the Fund's shares, such as data from Lipper Analytical Services,  Inc.
or other 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.
Shareholders  are entitled to one vote for each full share owned and  fractional
votes for fractional  shares.  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 are entitled to
one vote for each full share owned and fractional votes for fractional shares.

  The Fund does not have annual  meetings.  The Fund will have special  meetings
from time to time as required under its Restatement of Trust Agreement and under
the 1940  Act.  As  provided  in the  Fund's  Restatement  of  Trust  Agreement,
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.   The  Fund  is   prepared  to  assist   shareholders   in
communications  with one another for the purpose of convening  such a meeting as
prescribed by Section 16(c) of the 1940 Act.

                      ADDITIONAL INVESTMENT INFORMATION
- ------------------------------------------------------------------------------

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

CORPORATE BOND RATINGS
  Higher yields are usually available on securities that are lower rated or that
are  unrated.  Bonds  rated  Baa by  Moody's  are  considered  as  medium  grade
obligations  which are neither highly  protected nor poorly secured.  Debt rated
BBB by S&P is regarded as having an adequate  capacity to pay interest and repay
principal,  although  adverse  economic  conditions 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.  Lower rated securities are usually defined as
Baa or lower by Moody's or BBB or lower by S&P.  The Fund may  purchase  unrated
securities, which are not necessarily of lower quality than rated securities but
may not be attractive to as many buyers.  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 CI 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 which 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 which are rated Ca by Moody's represent  obligations which are speculative
in a high  degree.  Such  issues  are  often in  default  or have  other  market
shortcomings.  Bonds which are rated C by Moody's are the lowest  rated class of
bonds, and issues so rated can be regarded as having extremely poor prospects of
ever attaining any real investment standing.

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

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

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

PAYMENT-IN-KIND SECURITIES
  Payment-in-kind   securities   pay  interest  in  either  cash  or  additional
securities,  at the issuer's option, for a specified period. The issuer's option
to pay in additional securities typically ranges from one to six years, compared
to an average  maturity for all PIK securities of eleven years.  Call protection
and sinking fund features are  comparable to those offered on  traditional  debt
issues.

  PIKs,  like zero coupon bonds,  are designed to give an issuer  flexibility in
managing cash flow. Several PIKs are senior debt. In other cases, where PIKs are
subordinated, most senior lenders view them as equity equivalents.

  An  advantage of PIKs for the issuer -- as with zero coupon  securities  -- is
that interest payments are automatically  compounded  (reinvested) at the stated
coupon rate, which is not the case with cash-paying  securities.  However,  PIKs
are  gaining  popularity  over  zeros  since  interest  payments  in  additional
securities can be monetized and are more tangible than accretion of a discount.

  As a group, PIK bonds trade flat (i.e., without accrued interest). Their price
is expected to reflect an amount  representing  accreted interest since the last
payment.  PIKs  generally  trade at higher yields than  comparable  cash- paying
securities  of the same issuer.  Their premium yield is the result of the lesser
desirability of non-cash interest, the more limited audience for non-cash paying
securities, and the fact that many PIKs have been issued to equity investors who
do not normally own or hold such securities.

  Calculating  the true yield on a PIK security  requires a discounted cash flow
analysis if the  security  (ex  interest)  is trading at a premium or a discount
because  the  realizable  value of  additional  payments is equal to the current
market value of the underlying security, not par.

  Regardless  of  whether  PIK  securities  are  senior or deeply  subordinated,
issuers are highly  motivated to retire them because they are usually their most
costly form of capital.

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

REPURCHASE AGREEMENTS
  The Fund may enter into repurchase agreements with member banks of the Federal
Reserve  System  having at least $1 billion in assets,  primary  dealers in U.S.
government securities or other financial institutions believed by Keystone to be
creditworthy.  Such persons must be  registered  as U.S.  government  securities
dealers with an appropriate regulatory organization.  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 having a
value not less than the repurchase price (including  accrued  interest) and will
subsequently  monitor the account to ensure  such value is  maintained.  Reverse
repurchase  agreements  involve the risk that the market value of the securities
the Fund is obligated to  repurchase  may decline  below the  repurchase  price.
Borrowing and reverse  repurchase  agreements  magnify the potential for gain or
loss on the  portfolio  securities  of the Fund  and,  therefore,  increase  the
possibility  of  fluctuation  in the Fund's net asset value.  Such practices may
constitute  leveraging.  In the event the  buyer of  securities  under a reverse
repurchase  agreement files for bankruptcy or becomes  insolvent,  such buyer or
its trustee or receiver may receive an extension of time to determine whether to
enforce the Fund's obligation to repurchase the securities and the Fund's use of
the proceeds of the reverse  repurchase  agreement may effectively be restricted
pending such determination.  The staff of the Securities and Exchange Commission
has taken the position that the 1940 Act treats reverse repurchase agreements as
being included in the percentage limit on borrowings imposed on the Fund.

"WHEN ISSUED" AND "FORWARD COMMITMENT" TRANSACTIONS
  The Fund may also  purchase  securities  on a when issued or delayed  delivery
basis and may purchase or sell securities on a forward  commitment  basis.  When
issued and delayed delivery  transactions arise when securities are purchased 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 purchase.  A forward  commitment  transaction  is an agreement by the Fund to
purchase or sell securities at a specified  future date. The Fund may also enter
into foreign  currency  forward  contracts which are described in more detail in
the Section of this Exhibit entitled "Foreign Currency  Transactions."  When the
Fund engages in these  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, delayed delivery and forward commitment 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.  The Securities and Exchange Commission
has established  certain  requirements to assure that a Fund is able to meet its
obligations  under these  contracts,  for  example a separate  account of liquid
assets equal to the value of such purchase  commitments may be maintained  until
payment is made. When issued, delayed delivery and firm commitment  transactions
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 any of these
transactions, it will do so for the purpose of acquiring portfolio securities or
currencies consistent with its investment objective and policies and not for the
purpose of investment  leverage.  The Fund  currently  does not intend to invest
more than 5% of its assets in when issued or delayed delivery transactions.

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

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

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

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

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

  Debt instruments that incorporate one or more of these building blocks for the
purpose of determining the principal  amount of and/or rate of interest  payable
on the debt  instruments  are often referred to as "structured  securities."  An
example of this type of structured  security is indexed  commercial  paper.  The
term is also used to describe certain  securities  issued in connection with the
restructuring of certain foreign obligations. See "Indexed Commercial Paper" and
"Structured  Securities"  below. The term "derivative" is also sometimes used to
describe  securities  involving  rights to a portion  of the cash  flows from an
underlying  pool of  mortgages  or other  assets from which  payments are passed
through to the owner of, or that  collateralize,  the securities.  See "Mortgage
Related Securities,"  "Collateralized  Mortgage  Obligations,"  "Adjustable Rate
Mortgage  Securities,"  "Stripped Mortgage  Securities,"  "Mortgage Securities -
Special  Considerations,"  and "Other  Asset-Backed  Securities"  and the Fund's
statement of additional information.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

FOREIGN CURRENCY TRANSACTIONS
  As discussed above, the Fund may invest in securities of foreign issuers. When
the Fund invests in foreign  securities,  they usually  will be  denominated  in
foreign  currencies,  and  the  Fund  temporarily  may  hold  funds  in  foreign
currencies.  Thus,  the value of Fund  shares  will be  affected  by  changes in
exchange rates.

  As one way of managing  exchange  rate risk,  in  addition  to  entering  into
currency futures  contracts,  the Fund may enter into forward currency  exchange
contracts  (agreements to purchase or sell  currencies at a specified  price and
date).  The exchange rate for the  transaction  (the amount of currency the Fund
will deliver or receive when the contract is  completed)  is fixed when the Fund
enters into the  contract.  The Fund usually will enter into these  contracts to
stabilize the U.S.  dollar value of a security it has agreed to buy or sell. The
Fund intends to use these contracts to hedge the U.S. dollar value of a security
it already owns, particularly if the Fund expects a decrease in the value of the
currency in which the foreign  security is  denominated.  Although the Fund will
attempt to benefit  from using  forward  contracts,  the  success of its hedging
strategy  will depend on  Keystone's  ability to predict  accurately  the future
exchange rates between foreign  currencies and the U.S. dollar. The value of the
Fund's investments denominated in foreign currencies will depend on the relative
strength of those currencies and the U.S.  dollar,  and the Fund may be affected
favorably or unfavorably  by changes in the exchange  rates or exchange  control
regulations  between  foreign  currencies  and the  dollar.  Changes  in foreign
currency  exchange  rates also may affect the value of  dividends  and  interest
earned,  gains and losses  realized on the sale of securities and net investment
income  and  gains,  if any,  to be  distributed  to  shareholders  by the Fund.
Although the Fund does not currently intend to do so, the Fund may also purchase
and sell  options  related  to foreign  currencies.  The Fund does not intend to
enter into foreign currency  transactions for speculation or leverage.

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

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

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

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

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

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

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

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

INVERSE  FLOATING  RATE  COLLATERALIZED  MORTGAGE  OBLIGATIONS.  In  addition to
investing in fixed rate and  adjustable  rate CMOs,  the Fund may also invest in
CMOs with rates that move inversely to market rates ("inverse floaters").

  An inverse floater bears an interst rate that resets in the opposite direction
of the change in a specified interest rate index. As market interest rates rise,
the  interest  rate on the inverse  floater goes down,  and vice versa.  Inverse
floaters  tend to exhibit  greater price  volatility  than  fixed-rate  bonds of
similar maturity and credit quality.  The interest rates on inverse floaters may
be significantly  reduced,  even to zero, if interest rates rise. Moreover,  the
secondary  market for inverse  floaters may be limited in rising  interest  rate
environments.

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

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

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

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

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

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

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

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

VARIABLE,  FLOATING AND  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.

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

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

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

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

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

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

   The Fund is an  open-end,  diversified  management  investment  company.  The
Fund's investment  objective is to provide shareholders with generous income. To
achieve this objective,  the Fund invests  primarily in corporate bonds, and its
portfolio  ordinarily  includes a substantial  number of bonds that, as a class,
sell at discounts from par value and are rated by Standard & Poor's  Corporation
("S&P")  as below  investment  grade  (BBB).  While  Keystone  Management,  Inc.
("Keystone  Management") and Keystone  Custodian Funds, Inc.  ("Keystone"),  the
Fund's investment  manager and adviser,  respectively,  perform their own credit
analyses of the Fund's investments and do not rely on ratings assigned by rating
services,  bonds  rated  below  investment  grade are,  on  balance,  considered
predominantly speculative.

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

   The following  restrictions  are fundamental and may not be changed without a
vote of the holders of a majority,  as defined in the Investment  Company Act of
1940 (the "1940 Act"), of the Fund's  outstanding  shares. The Fund shall not do
any of the following:

   (1) invest more than 5% of its total assets, computed at market value, in the
securities of any one issuer,  other than securities issued or guaranteed by the
United States ("U.S.") government, its agencies or instrumentalities;

   (2) invest more than 5% of the value of its total assets in  companies  which
have been in operation for less than three years;

   (3) borrow  money,  except that the Fund may (a) borrow  money from banks for
temporary or emergency  purposes in aggregate  amounts up to 10% of the value of
the Fund's net assets  (computed at cost); or (b) enter into reverse  repurchase
agreements (bank  borrowings and reverse  repurchase  agreements,  in aggregate,
shall not exceed 10% of the value of the Fund's net assets);

   (4) underwrite securities,  except that the Fund may purchase securities from
issuers thereof or others and dispose of such securities in a manner  consistent
with its other investment policies;  in the disposition of restricted securities
the Fund may be deemed to be an underwriter, as defined in the Securities Act of
1933 (the "1933 Act");

   (5) purchase or sell real estate or interests in real estate,  except that it
may  purchase  and sell  securities  secured by real  estate and  securities  of
companies which invest in real estate, and will not purchase or sell commodities
or  commodity  contracts,  except  that the Fund may engage in currency or other
financial futures contracts and related options transactions;

   (6) invest for the primary  purpose of exercising  control over or management
of any issuer;

   (7) make margin purchases or short sales of securities;

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

   (9) invest  more than 25% of its assets in the  securities  of issuers in any
single  industry,  other than  securities  issued by banks and  savings and loan
associations  or securities  issued or guaranteed  by the U.S.  government,  its
agencies or instrumentalities; and

   (10) purchase the  securities of any other  investment  company except in the
open market and at customary brokerage rates and in no event more than 3% of the
voting securities of any investment company.

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

   Although not fundamental  restrictions or policies  requiring a shareholders'
vote to change,  the Fund has undertaken to a securities  authority of a foreign
country that, so long as the shares of the Fund are  registered for sale in that
country  (1) the Fund will not  invest  in the  securities  of other  investment
companies,  including unit  investment  trusts;  (2) the Fund will not invest in
real  estate  investment  trusts or  limited  partnerships  whose  purpose is to
acquire real estate for investment  purposes only, in accordance with principles
of  diversification;   (3)  upon  payment  of  the  purchase  price,  shares  of
corresponding  value shall be issued without undue delay in accordance with Rule
22(c)(1) of the 1940 Act; (4) the Fund will suspend the right of redemption only
in  accordance  with Rule 22(e) of the 1940 Act; (5) all cash and  securities of
the Fund shall be  received  by and  disbursed  or  delivered  by or through the
Fund's  custodian  or  transfer  agent;  (6)  amounts  borrowed  from the Fund's
custodian bank for  extraordinary  or emergency  purposes  pursuant to the third
fundamental  investment restriction enumerated above shall not exceed 10% of the
Fund's net asset value;  (7) the Fund will maintain its present  election  under
Rule  18(f)  of the 1940  Act to  redeem  in kind  only in  accordance  with the
provisions  of such  Rule;  and (8)  assets  of the Fund may not be  pledged  or
otherwise  encumbered nor be transferred or assigned for the purpose of securing
a debt except in the course of portfolio trading.

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

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

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

   Current  values for the Fund's  portfolio  securities  are  determined in the
following manner:

   (1) Securities  traded on an established  exchange are valued on the basis of
the last sales price on the exchange where primarily traded prior to the time of
the  valuation.  Securities  traded in the  over-the-counter  market,  for which
complete quotations are readily available, are valued at the mean of the bid and
asked prices at the time of valuation.

   (2) Short-term  instruments  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. In any case, such valuation reflects fair
value as determined by the Board of Trustees.

   (3) Short-term money market  instruments having maturities of 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. In any case, such valuation reflects fair
value as determined by the Board of Trustees.

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

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

- ------------------------------------------------------------------------------
                           DISTRIBUTIONS AND TAXES
- ------------------------------------------------------------------------------

   The Fund  ordinarily  distributes its net capital gains in shares of the Fund
or, at the option of the  shareholder,  in cash. All  shareholders  may reinvest
dividends and  distributions  without  being subject to a deferred  sales charge
when shares so purchased are redeemed.  Shareholders who have opted prior to the
record  date to receive  shares  with  regard to  capital  gains  and/or  income
distributions will have the number of such shares determined on the basis of the
share value  computed at the end of the day on the record date after  adjustment
for the  distribution.  Net asset  value is used in  computing  the  appropriate
number of shares in both a capital gains distribution and an income distribution
reinvestment.  Account statements and/or checks as appropriate will be mailed to
shareholders  by the 15th of the  appropriate  month.  Unless the Fund  receives
instructions to the contrary from a shareholder  before the record date, it will
assume that the shareholder  wishes to receive both capital gains  distributions
and  income  distributions  in shares.  Instructions  continue  in effect  until
changed in writing.

   The Fund's income  distributions  are largely  derived from interest on bonds
and thus are not to any significant  degree  eligible,  in whole or in part, for
the corporate 70% dividends received  deduction.  Distributed  long-term capital
gains are  taxable as such to the  shareholder  whether  received  in cash or in
additional  Fund  shares and  regardless  of the period of time Fund shares have
been held by the  shareholder.  Distributions  designated by the Fund as capital
gains dividends are not eligible for the corporate dividends received deduction.
If the net asset  value of shares  was  reduced  below a  shareholder's  cost by
distribution of capital gains realized on sales of securities, such distribution
to the extent of the reduction would be a return of investment though taxable as
stated  above.  Since  distributions  of capital  gains  depend upon  securities
profits actually  realized,  they may or may not occur.  The foregoing  comments
relating  to the  taxation of  dividends  and  distributions  paid on the Fund's
shares  relate  solely  to  federal   income   taxation.   Such   dividends  and
distributions may also be subject to state and local taxes.

   When the Fund makes a  distribution,  it intends to  distribute  only its net
capital  gains  and such  income as has been  predetermined,  to the best of the
Fund's  ability,  to be taxable as ordinary  income.  Therefore,  net investment
income  distributions  will not be made on the basis of distributable  income as
computed  on the books of the Fund,  but will be made on a  federal  income  tax
basis.  Shareholders of the Fund will be advised  annually of the federal income
tax status of distributions.

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

   In order to reimburse the Fund for certain  expenses  relating to the sale of
its shares (see "Distribution  Plan"), a 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 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 the
National Association of Securities Dealers, Inc. ("NASD"),  paid to KDI. For the
year ended July 31, 1994, the Fund recovered $179,947 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 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 contingent deferred sales charge
is imposed  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 deferred sales charge is imposed on
amounts redeemed thereafter.

   The following  example  illustrates the operation of the contingent  deferred
sales charge. Assume that an investor makes a purchase payment of $10,000 during
the calendar  year 1994 and on a given date in 1995 the value of the  investor's
account  has  grown  through   investment   performance   and   reinvestment  of
distributions to $12,000.  On such date in 1995, 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 proceeds (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) and would
total $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 deferred  sales  charge 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.

   Shares  also  may be  sold,  to  the  extent  permitted  by  applicable  law,
regulations,  interpretations  or  exemptions,  at net asset  value  without the
payment of  commissions  or the  imposition  of a  deferred  sales  charge  upon
redemption of shares by (1) officers,  Directors,  Trustees, full-time employees
and sales representatives of Keystone Management, Keystone, Keystone Group, Inc.
("Keystone Group"),  Harbor Capital Management Company, Inc., their subsidiaries
and KDI 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 deferred  sales  charge is imposed on a  redemption  of Fund
shares  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 other  Keystone  Custodian Fund (as  hereinafter  defined),  Keystone
Precious Metals Holdings,  Inc., Keystone  International Fund Inc., Keystone Tax
Exempt Trust,  Keystone Tax Free Fund, Keystone Liquid Trust and/or any Keystone
America Fund (as  hereinafter  defined) 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.

- ------------------------------------------------------------------------------
                           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. 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 (the "Distribution Plan").

   The Fund's  Distribution Plan provides that the Fund may expend up to 0.3125%
quarterly (approximately 1.25% annually) of the 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 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 KDI).

   Payments  under the  Distribution  Plan are currently  made to KDI (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 of shares maintained
by the recipients outstanding on the Fund's books for specific periods.  Amounts
paid or  accrued  to KDI under (1) and (2) in the  aggregate  may not exceed the
annual limitation referred to above. KDI generally reallows to brokers or others
a commission equal to 4% 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.

   If the Fund is  unable  to pay KDI a  commission  on a new sale  because  the
annual  maximum  (0.75% of  average  daily net  assets)  has been  reached,  KDI
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 pay KDI such amounts that exceed the Distribution Plan
limitation,  KDI  intends  to seek full  payment of such  amounts  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.  KDI currently intends to seek payment of interest only
on such charges paid or accrued by KDI subsequent to July 7, 1992. If the Fund's
independent  Trustees  ("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. If the  Distribution
Plan is  terminated,  KDI will ask the  Independent  Trustees  to take  whatever
action they deem appropriate under the circumstances  with respect to payment of
such amounts.

   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 ("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 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 Rule 12b-1 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 is required to commit the
selection  and  nomination  of  candidates  for  Independent   Trustees  to  the
discretion of the Independent Trustees.

   During the fiscal  year ended  July 31,  1994,  the Fund paid KDI  $9,079,585
under the  Distribution  Plan. KDI earned  $4,485,981 in commissions and service
fees,  of which  amount  KDI  actually  received  $2,334,230  after  payment  of
commissions and service fees to others of $6,745,355.

   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. 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.

   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.

- ------------------------------------------------------------------------------
                             REDEMPTIONS IN KIND
- ------------------------------------------------------------------------------

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

- ------------------------------------------------------------------------------
                               THE TRUST AGREEMENT
- ------------------------------------------------------------------------------

   The  Fund  is a  Pennsylvania  common  law  trust  established  under a Trust
Agreement dated July 15, 1935, as amended and restated on December 19, 1989 (the
"Restatement   of  Trust   Agreement").   The  Restatement  of  Trust  Agreement
restructured  the Fund so that its operation would be  substantially  similar to
that of most other mutual funds. The Restatement of Trust Agreement provides for
a Board of  Trustees  and enables  the Fund to enter into an  agreement  with an
investment manager and/or adviser to provide the Fund with investment  advisory,
management  and  administrative  services.  A copy of the  Restatement  of Trust
Agreement is filed as an exhibit to the Fund's Registration  Statement, of which
this statement of additional information is a part. This summary is qualified in
its entirety by reference to the Restatement of Trust Agreement.

DESCRIPTION OF SHARES

   The  Restatement of Trust  Agreement  authorizes the issuance of an unlimited
number of shares of beneficial  interest and the creation of  additional  series
and/or classes of series of shares of the Fund.  Each share  represents an equal
proportionate  interest in the Fund with each other  share of that  class.  Upon
liquidation,  shares are entitled to a pro rata share in the net assets of their
class of Fund  shares.  Shareholders  shall  have no  preemptive  or  conversion
rights.  Shares are  transferable.  The Fund currently intends to issue only one
class of shares.

SHAREHOLDER LIABILITY

   Pursuant  to court  decisions  or other  theories of law,  shareholders  of a
Pennsylvania  common law trust could possibly be held personally  liable for the
obligations  of  the  Fund.  The  possibility  of  Fund  shareholders  incurring
financial loss under such circumstances appears to be remote,  however,  because
the  Restatement  of Trust  Agreement  (1)  contains  an express  disclaimer  of
shareholder  liability for  obligations of the Fund; (2) requires that notice of
such  disclaimer be given in each  agreement,  obligation or instrument  entered
into  or  executed  by  the  Fund  or  the   Trustees;   and  (3)  provides  for
indemnification  out of Fund property for any shareholder held personally liable
for the obligations of the Fund.

VOTING RIGHTS

   Under the terms of the Restatement of Trust Agreement, the Fund does not hold
annual  meetings.  At meetings called for the initial election of Trustees or to
consider  other  matters,  shares are  entitled  to one vote per  share.  Shares
generally vote together as one class on all matters. No amendment may be made to
the  Restatement of Trust  Agreement that adversely  affects any class of shares
without the  approval of a majority of the shares of that class.  There shall be
no cumulative voting in the election of Trustees.

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

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


LIMITATION OF TRUSTEES' LIABILITY
   The  Restatement of Trust  Agreement  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  Restatement  of Trust  Agreement  shall  protect a Trustee
against any liability for his willful  misfeasance,  bad faith, gross negligence
or reckless disregard of his duties.

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

- ------------------------------------------------------------------------------
                             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 other Keystone Custodian Funds and to certain other funds
in the Keystone Group of Mutual Funds.

   Except  as  otherwise  noted  below,  pursuant  to an  Investment  Management
Agreement  with the Fund dated  August 19, 1993  ("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

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

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

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

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

   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. Keystone Management is not required,  however, to make
such  reimbursements  to the extent it 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  will continue in effect only if approved at least
annually  by the Fund's  Board of  Trustees  or by a vote of a  majority  of the
outstanding shares, and such renewal has been approved by the vote of a majority
of the  Independent  Trustees cast in person at a meeting called for the purpose
of voting on such approval. The Management Agreement may be terminated,  without
penalty, on 60 days' written notice by the Fund's Board of Trustees or by a vote
of a majority of outstanding  shares.  The  Management  Agreement will terminate
automatically upon its "assignment" as that term is defined in the 1940 Act.

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

   Pursuant to a Principal  Underwriting  Agreement  dated  August 19, 1993 (the
"Underwriting  Agreement"),  KDI acts as the Fund's Principal Underwriter.  KDI,
located  at  200  Berkeley  Street,  Boston,   Massachusetts  02116-5034,  is  a
wholly-owned  subsidiary of Keystone.  KDI, as agent, has agreed to use its best
efforts  to find  purchasers  for the Fund's  shares.  KDI may retain and employ
representatives to promote distribution of the shares and may obtain orders from
brokers, dealers and others, acting as principals,  for sales of shares to them.
The Underwriting Agreement provides that KDI will bear the expense of preparing,
printing and distributing advertising and sales literature and prospectuses used
by it. In its capacity as Principal  Underwriter,  KDI may receive payments from
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 KDI's  judgment it could  benefit the sales of Fund
shares, KDI may use its discretion in providing to selected dealers  promotional
materials and selling aids,  including,  but not limited to, personal computers,
related software and Fund data files.

   During  the  year  ended  July  31,  1994,  the Fund  recovered  $179,947  in
contingent  deferred  sales  charges.  During the same  year,  the Fund paid KDI
$9,079,585  under the  Distribution  Plan. The amount paid by the Fund under its
Distribution  Plan, net of contingent  deferred  sales  charges,  was $8,899,638
(0.96% of the Fund's  average daily net asset value).  For the fiscal year ended
July 31, 1994, KDI earned  $4,485,981 in commissions  and service fees, of which
amount KDI actually  received  $2,334,230  after  payments of commissions on new
sales and service fees to dealers and others of $6,745,355. During the year, KDI
also received $1,014,043 in contingent deferred sales charges. At July 31, 1994,
KDI's total unreimbursed expenses amounted to $10,565,436 (1.38% of net assets).
The right to  certain  portions  of this  amount,  if and when  receivable,  was
assigned by KDI in 1988 in connection with a financial  transaction.  As of July
31, 1994, $7,396,647 of the amount remained outstanding.

                              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 or Keystone
under the Advisory Agreement.  The cost, value and specific  application of such
information  are  indeterminable  and cannot be practically  allocated among the
Fund and other  clients of Keystone  Management  or Keystone who may  indirectly
benefit  from the  availability  of such  information.  Similarly,  the Fund may
indirectly  benefit from  information made available as a result of transactions
effected for such other clients. Under the Management Agreement and the Advisory
Agreement,  Keystone  Management  and  Keystone  are  permitted  to  pay  higher
brokerage  commissions  for brokerage and research  services in accordance  with
Section  28(e) of the  Securities  Exchange Act of 1934.  In the event  Keystone
Management  and  Keystone do follow such a practice,  they will do so on a basis
which is fair and equitable to the Fund.

   The  Fund  expects  that  purchases  and  sales  of bonds  and  money  market
instruments  usually  will be  principal  transactions.  Bonds and money  market
instruments  are  normally  purchased  directly  from  the  issuer  or  from  an
underwriter  or  market  maker  for the  securities.  There  usually  will be no
brokerage  commissions  paid by the  Fund  for such  purchases.  Purchases  from
underwriters  will  include  the  underwriting   commission  or  concession  and
purchases from dealers  serving as market makers will include 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. The
Fund's Board of Trustees,  however,  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 July 31,  1992,  1993 and 1994 the Fund paid no
brokerage commissions.

   In no instance are portfolio  securities  purchased  from or sold to Keystone
Management,  Keystone, KDI 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 five and ten year periods
ending July 31,  1994 were  40.52% and  121.91%,  respectively.  The  compounded
average  rates of return for the one,  five and ten year periods  ended July 31,
1994 were (3.14)%, 7.04% and 8.30%, respectively.

   Current   yield   quotations  as  they  may  appear  from  time  to  time  in
advertisements will consist of a quotation based on a 30-day period ended on the
date of the most recent balance sheet of the Fund,  computed by dividing the net
investment  income per share  earned  during the period by the maximum  offering
price per share on the last day of the base period. The Fund's current yield for
the 30-day period ended July 31, 1994 was 8.07%.

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

                         CORPORATE BOND RATINGS

A.  S&P CORPORATE BOND RATINGS

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

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

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

   b. Nature of and provisions of the obligation; and

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

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

   Bond ratings are as follows:

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

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

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

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

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

   6. CI - The rating CI is  reserved  for income  bonds on which no interest is
being paid.

   7. D - Debt rated D is in default,  and payment of interest and/or  repayment
of principal is in arrears.

B.  MOODY'S CORPORATE BOND RATINGS

   Moody's ratings are as follows:

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

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

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

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


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

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

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

   8. Ca - Bonds which are rated Ca represent  obligations which are speculative
in a high  degree.  Such  issues  are  often in  default  or have  other  market
shortcomings.

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

   Moody's  applies  numerical  modifiers,  1, 2 AND 3 in  each  generic  rating
classification  from Aa  through B in its  corporate  bond  rating  system.  The
modifier 1 indicates  that the  security  ranks in the higher end of its generic
rating category;  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.

                     ZERO COUPON "STRIPPED" BONDS

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

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

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

                         PAYMENT-IN-KIND SECURITIES

   Payment-in-kind  ("PIK") securities pay interest in either cash or additional
securities,  at the issuer's option, for a specified period. The issuer's option
to pay in additional securities typically ranges from one to six years, compared
to an average  maturity for all PIK securities of eleven years.  Call protection
and sinking fund features are  comparable to those offered on  traditional  debt
issues.

   PIKs, like zero coupon bonds, are designated to give an issuer flexibility in
managing cash flow. Several PIKs are senior debt. In other cases, where PIKs are
subordinated, most senior lenders view them as equity equivalents.

   An  advantage  of PIKs for the issuer - as with zero coupon  securities  - is
that interest payments are automatically  compounded  (reinvested) at the stated
coupon rate, which is not the case with cash-paying  securities.  However,  PIKs
are  gaining  popularity  over  zeros  since  interest  payments  in  additional
securities can be monetized and are more tangible than accretion of a discount.

   As a group,  PIK bonds trade flat (i.e.,  without  accrued  interest).  Their
price is expected to reflect an amount representing  accreted interest since the
last payment. PIKs generally trade at higher yields than comparable  cash-paying
securities  of the same issuer.  Their premium yield is the result of the lesser
desirability of non-cash interest, the more limited audience for non-cash paying
securities, and the fact that many PIKs have been issued to equity investors who
do not normally own or hold such securities.

   Calculating the true yield on a PIK security  requires a discounted cash flow
analysis if the  security  (ex  interest) is trading at a premium or a discount,
because  the  realizable  value of  additional  payments is equal to the current
market value of the underlying security, not par.

   Regardless  of whether  PIK  securities  are  senior or deeply  subordinated,
issuers are highly  motivated to retire them because they are usually their most
costly form of capital.  Sixty-eight  percent of the PIK debentures issued prior
to 1987  have  already  been  redeemed,  and  approximately  35% of the over $10
billion PIK debentures issued through year-end 1988 have been retired.

                         EQUIPMENT TRUST CERTIFICATES

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

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

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

                             LIMITED PARTNERSHIPS

   The Fund may invest in limited  and master  limited  partnerships.  A limited
partnership is a partnership consisting of one or more general partners, jointly
and  severally  responsible  as ordinary  partners,  and by whom the business is
conducted,  and one or more limited  partners who contribute  cash as capital to
the  partnership  and  who  generally  are  not  liable  for  the  debts  of the
partnership beyond the amounts contributed. Limited partners are not involved in
the day-to-day management of the partnership. They receive income, capital gains
and other tax benefits  associated  with the  partnership  project in accordance
with  terms   established  in  the   partnership   agreement.   Typical  limited
partnerships  are in real estate,  oil and gas and equipment  leasing,  but they
also finance movies, research and development and other projects.

   For an organization  classified as a partnership  under the Internal  Revenue
Code, each item of income,  gain, loss, deduction and credit is not taxed at the
partnership  level but flows through to the holder of the partnership unit. This
allows the  partnership  to avoid  taxation  and to pass  through  income to the
holder of the partnership unit at lower individual rates.

   A master limited  partnership is a publicly traded limited  partnership.  The
partnership units are registered with the Securities and Exchange Commission and
are freely exchanged on a securities exchange or in the over-the-counter market.

                           MOODY'S PREFERRED STOCK RATINGS

   Preferred stock ratings and their definitions are as follows:

   1.  aaa:  An issue  which  is rated  aaa is  considered  to be a  top-quality
preferred stock.  This rating indicates good asset protection and the least risk
of dividend impairment within the universe of preferred stocks.

   2. aa: An issue which is rated aa is considered a high-grade preferred stock.
This rating  indicates  that there is a reasonable  assurance  that earnings and
asset  protection  will remain  relatively  well  maintained in the  foreseeable
future.

   3. a: An issue which is rated a is  considered  to be an  upper-medium  grade
preferred  stock.  While risks are judged to be somewhat greater then in the aaa
and aa classification, earnings and asset protection are, nevertheless, expected
to be  maintained  at  adequate  levels.

   4.  baa:  An issue  which is rated  baa is  considered  to be a  medium-grade
preferred stock, neither highly protected nor poorly secured. Earnings and asset
protection  appear  adequate at present but may be  questionable  over any great
length of time.

   5. ba: An issue which is rated ba is considered to have speculative  elements
and its future cannot be considered well assured.  Earnings and asset protection
may  be  very  moderate  and  not  well  safeguarded   during  adverse  periods.
Uncertainty of position characterizes preferred stocks in this class.

   Moody's applies numerical modifiers 1, 2 and 3 in each rating classification.
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.

                           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 Investors Service,  Inc. (Fitch).  These
ratings and other money market instruments are described as follows:

COMMERCIAL PAPER RATINGS

   Commercial   paper  rated  A-1  by  Standard  &  Poor's  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.

   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 which exist with the issuer; and (8) recognition by the management
of  obligations  which  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.

   The rating F-1 is the highest  rating  assigned  by Fitch.  Among the factors
considered  by Fitch in assigning  this rating are: (1) the issuer's  liquidity;
(2) its standing in the industry;  (3) the size of its debt;  (4) its ability to
service  its debt;  (5) its  profitability;  (6) its return on  equity;  (7) its
alternative  sources of  financing;  and (8) its  ability to access the  capital
markets.  Analysis of the  relative  strength  or weakness of these  factors and
others determines whether an issuer's commercial paper is rated F-1.

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 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  World  Bank,  the  Asian  Development  Bank  or the  InterAmerican
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 which are members of the Federal  Reserve System
or the Federal  Deposit  Insurance  Corporation  and have at least $1 billion in
deposits as of the date of their most recently published financial statements.

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

BANKERS' ACCEPTANCES

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

                            OPTIONS TRANSACTIONS

WRITING COVERED OPTIONS

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

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

   An option position may be closed out only in a secondary market for an option
of the same series.  Although the Fund will  generally  write only those options
for which there appears to be an active secondary market,  there is no assurance
that a liquid  secondary  market  will  exist for any  particular  option at any
particular  time,  and for some options no secondary  market may exist.  In such
event it might not be possible to effect a closing  transaction  in a particular
option.  If the Fund as a  covered  call  option  writer  is  unable to effect a
closing  purchase  transaction,  it will  not be able  to  sell  the  underlying
securities  until the option  expires or it delivers the  underlying  securities
upon exercise.

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

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

PURCHASING PUT AND CALL OPTIONS

   The Fund can close out a put or call  option it has  written by  effecting  a
closing purchase transaction;  for example, the Fund may close out a put or call
option it has written by buying an option  identical  to the one it has written.
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.  If a covered  call option  writer  cannot  effect a closing
transaction,  it cannot sell the underlying  securities until the option expires
or is exercised.  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,  thereby  incurring  additional
transaction costs.

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

OPTION WRITING AND RELATED RISKS

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

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

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

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

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

OPTIONS TRADING MARKETS

   Options  which  the Fund  will  trade  are  generally  listed  on  Exchanges.
Exchanges  on which such  options  currently  are traded are the  Chicago  Board
Options Exchange and the American,  New York,  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  the  statement  of  additional
information.

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

SPECIAL CONSIDERATIONS APPLICABLE TO OPTIONS

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

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

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

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

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

   RISKS  PERTAINING TO THE SECONDARY  MARKET.  An option position may be closed
out only in a secondary  market for an option of the same  series.  Although the
Fund will generally purchase or write only those options for which there appears
to be an active secondary market,  there is no assurance that a liquid secondary
market will exist for any particular option at any particular time, and for some
options no secondary  market may exist.  In such event, it might not be possible
to effect closing  transactions in particular options,  with the result that the
Fund would have to exercise its options in order to realize any profit and might
incur transaction costs in connection  therewith.  If the Fund as a covered call
option writer is unable to effect a closing purchase  transaction in a secondary
market,  it will not be able to sell the  underlying  security  until the option
expires or it delivers the underlying security upon exercise.

   Reasons for the absence of a liquid  secondary  market include the following:
(i) insufficient trading interest in certain options;  (ii) restrictions imposed
on transactions;  (iii) trading halts, suspensions or other restrictions imposed
with  respect  to  particular   classes  or  series  of  options  or  underlying
securities;  (iv)  interruption of the normal  operations on an Exchange or by a
broker;  (v)  inadequacy of the  facilities of an Exchange,  the OCC or a broker
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  which 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  which  specify  currencies,   financial   instruments  or
financially based indices 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,  Government National Mortgage  Association  ("GNMA")
certificates,  90-day domestic bank  certificates of deposit,  90-day commercial
paper,  and 90-day  Eurodollar  certificates  of deposit.  It is  expected  that
futures   contracts  trading  in  additional   financial   instruments  will  be
authorized. The standard contract size is $100,000 for futures contracts in U.S.
Treasury bonds,  U.S. Treasury notes and GNMA  certificates,  and $1,000,000 for
the other designated  contracts.  While U.S. Treasury bonds, U.S. Treasury bills
and U.S.  Treasury  notes are  backed by the full  faith and  credit of the U.S.
government and GNMA certificates are guaranteed by a U.S. government agency, the
futures contracts in U.S. government  securities are not obligations of the U.S.
Treasury.

INDEX BASED FUTURES CONTRACTS

STOCK INDEX FUTURES CONTRACTS

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

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

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

OTHER INDEX BASED FUTURES CONTRACTS

   It is expected  that bond index and other  financially  based  index  futures
contracts  will be developed in the future.  It is  anticipated  that such index
based  futures  contracts  will be  structured  in the same  way as stock  index
futures  contracts  but will be measured by changes in interest  rates,  related
indices 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 a specified dollar amount times
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 commodity  futures  contracts is
analagous 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 or 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 CURRENCY AND OTHER FINANCIAL FUTURES
CONTRACTS OR RELATED OPTIONS

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

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

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

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

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

FEDERAL INCOME TAX TREATMENT

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

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

RISKS OF FUTURES CONTRACTS

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

   At best, the correlation  between changes in prices of futures  contracts and
of  the  securities  being  hedged  can  be  only  approximate.  The  degree  of
imperfection of correlation  depends upon  circumstances,  such as variations in
speculative  market demand for futures  contracts and for securities,  including
technical  influences  in futures  contracts  trading;  differences  between the
securities being hedged and the financial instruments and indices 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 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 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  rate  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 engage in currency futures contracts only for
hedging  purposes,  and not for  speculation.  The Fund may enter into  currency
futures  contracts for other  purposes if authorized to do so by the Board.  The
hedging  strategies  which will be used by the Fund in  connection  with foreign
currency  futures  contracts  are similar to those  described  above for forward
foreign currency exchange contracts.

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

FOREIGN CURRENCY OPTIONS TRANSACTIONS

   Foreign  currency  options (as opposed to futures) are traded 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 analagous 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
which may be  developed  from time to time and  which  are  consistent  with the
Fund's  investment  objective.  The Fund believes that no additional  techniques
have been identified for employment by the Fund in the foreseeable  future other
than those described above.


CURRENCY TRADING RISKS

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

EXCHANGE RATE RISK

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

MATURITY GAPS AND INTEREST RATE RISK

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

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

CREDIT RISK

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

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

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

COUNTRY RISK

   At  one  time  or  another,  virtually  every  country  has  interfered  with
international  transactions in its currency.  Interference has taken the form of
regulation of the local exchange market,  restrictions on foreign  investment by
residents or limits on inflows of investment funds from abroad. Governments take
such measures for example,  to improve control over the domestic  banking system
or to  influence  the pattern of receipts  and payments  between  residents  and
foreigners.   In  those  cases,  restrictions  on  the  exchange  market  or  on
international  transactions  are intended to affect the level or movement of the
exchange rate.  Occasionally  a serious  foreign  exchange  shortage may lead to
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 which  interfere with the
normal payments mechanism.  If government  regulations change and a counterparty
is either  forbidden to perform or is required to do something  extra,  then the
Fund might be left with an unintended  open  position or an unintended  maturity
mismatch.  Dealing with such  unintended long or short positions could result in
unanticipated costs to the Fund.

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

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

NOTES TO SCHEDULE OF INVESTMENTS 
(a) Securities which have defaulted on payment of interest and/or principal. The Fund has ceased accruing income on these 
    so identified. 
(b) All or a portion of these securities are restricted securities (i.e., securities which may not be publicly sold 
    without registration under the Federal Securities Act of 1933) which are valued using market quotations where readily 
    available. In the absence of market quotations, the securities are valued based upon their fair value determined under 
    procedures approved by the Board of Trustees. The Fund may make investments in an amount up to 15% of the value of the 
    Fund's net assets in such securities. Dates of acquisition and costs are set forth in parentheses after the title of 
    the restricted securities. On the date of acquisition there were no market quotations on similar securities and the 
    above securities were valued at acquisition cost. At July 31, 1994, the fair value of these restricted securities was 
    $102,262,224 (13% of net assets). The Fund will not pay the cost of disposition of the above restricted securities 
    other than ordinary brokerage fees, if any. 
(c) Effective yield (calculated at date of purchase) is the yield at which the bond accretes on an annual basis until 
    maturity date. 
(d) Non-income-producing security. 
(e) Affiliated issuers are those in which the Fund's holdings of an issuer represent 5% or more of the outstanding voting 
    securities of the issuer. The Fund has never owned enough of the outstanding voting securities of any issuer to have 
    control (as defined in the Investment Company Act of 1940) of that issuer. 
(f) The cost of investments for federal income tax purposes amounted to $812,674,775. Gross unrealized appreciation and 
    depreciation of investments, based on identified tax cost, at July 31, 1994, are as follows: 

    Gross unrealized appreciation          $  77,669,105 
    Gross unrealized depreciation           (128,837,785) 
    Net unrealized depreciation            $ (51,168,680)

(a) 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 July 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. 
(b) Effective August 1, 1993, the Fund adopted Statement of Position 93-2: "Determination, Disclosure, and Financial 
    Statement Presentation of Income, Capital Gain and Return of Capital Distributions by Investment Companies." As a 
    result, distribution amounts exceeding book basis 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 net realized capital gains." From January 31, 1990 until the date of adoption of the Statement of 
    Position, distribution amounts exceeding book basis investment income--net were charged to paid-in capital. 
(c) Portfolio turnover rate for periods ended on or after July 31, 1985 includes certain U.S. Government obligations. 
(d) Without contingent deferred sales charge (CDSC).

NOTES TO FINANCIAL STATEMENTS 

(1.) Significant Accounting Policies 

Keystone  B-4 High Income Bond Fund (the "Fund") is a common law 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  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. Investments are usually valued at the closing sales price, or, in the absence
of  sales  and for  over-the-counter  securities,  the  mean  of bid  and  asked
quotations.  Management  values the  following  securities at prices it deems in
good faith to be fair:  (a) securities  (including  restricted  securities)  for
which complete  quotations are not readily  available and (b) listed  securities
if, in the  opinion  of  management,  the last sales  price  does not  reflect a
current value or if no sale occurred.  Short-term  investments maturing in sixty
days when  purchased  which are held on the  sixtieth  day prior to maturity are
valued  at  amortized  cost  (market  value on the  sixtieth  day  adjusted  for
amortization  of premium or accretion of  discount),  which when  combined  with
accrued interest,  approximates market.  Short-term investments denominated in a
foreign currency are adjusted daily to reflect changes in exchange rates. Market
quotations  are not considered to be readily  available for long-term  corporate
bonds and  notes;  such  investments  are  stated at fair  value on the basis of
valuations  furnished  by a pricing  service,  approved by the  Trustees,  which
determines  valuations  for  normal  institutional-size  trading  units  of such
securities using methods based on market transactions for comparable  securities
and various  relationships  between securities which are generally recognized by
institutional traders.

A  futures  contract  is an  agreement  between  two  parties  to buy and sell a
specific amount of a commodity,  security, financial instrument, or, in the case
of a stock index,  cash at a set price on a future date.  Upon  entering  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.

Foreign  currency  amounts are translated into United States dollars as follows:
market  value of  investments,  assets  and  liabilities  at the  daily  rate of
exchange, purchases and sales of investments, income and expenses at the rate of
exchange prevailing on the respective dates of such transactions. Net unrealized
foreign    exchange    gains/losses    are    a    component    of    unrealized
appreciation/depreciation of investments.

B. 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 and dividend income is recorded on the ex-dividend
date.  All original issue  discounts are amortized for both financial  reporting
and federal income tax purposes.  Distributions  to shareholders are recorded at
the close of business on the record date.

C. The Fund has qualified,  and intends to qualify in the future, as a regulated
investment  company  under  the  Internal  Revenue  Code  of  1986,  as  amended
("Internal Revenue Code").  Thus, the Fund is relieved of any federal income tax
liability  by  distributing  all of its net  taxable  investment  income and net
taxable  capital gains, if any, to its  shareholders.  The Fund intends to avoid
excise tax  liability  by making the required  distributions  under the Internal
Revenue Code.

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

E. When the Fund enters into a repurchase  agreement  (a purchase of  securities
whereby the seller agrees to repurchase the securities at a mutually agreed upon
date and price) the repurchase  price of the securities will generally equal the
amount paid by the Fund plus a negotiated  interest amount. The seller under the
repurchase  agreement will be required to provide  securities  ("collateral") to
the  Fund  whose  value  will be  maintained  at an  amount  not  less  than the
repurchase  price,  and  which  generally  will  be  maintained  at  101% of the
repurchase  price.  The Fund  monitors the value of collateral on a daily basis,
and if the value of 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. In connection with portfolio purchases and sales of securities denominated in
a foreign  currency,  the Fund may enter into forward foreign currency  exchange
contracts ("contracts"). Additionally, from time to time the Fund may enter into
contracts to hedge certain foreign  currency  assets.  Contracts are recorded at
market  value.  Realized  gains and losses  arising from such  transactions  are
included in net realized gain (loss) on foreign currency  related  transactions.
The Fund is subject to the credit  risk that the other  party will not  complete
the obligations of the contract.

G. The Fund  distributes  net investment  income to  shareholders  quarterly and
capital gains, if any, annually. Distributions are determined in accordance with
income tax regulations. Distributions from taxable net investment income and net
capital gains can exceed book basis net investment income and net capital gains.
Effective  August  1,  1993,  the  Fund  adopted  Statement  of  Position  93-2:
Determination,  Disclosure,  and  Financial  Statement  Presentation  of Income,
Capital Gain and Return of Capital Distributions by Investment  Companies.  As a
result of this statement,  the Fund changed the  classification of distributions
to shareholders to better disclose the differences  between financial  statement
amounts and distributions  determined in accordance with income tax regulations.
Accordingly,  amounts as of July 31, 1994 have been  reclassified  to reflect an
increase in undistributed investment income--net  (accumulated  distributions in
excess of investment  income--net)  of $9,781,768  and decreases in  accumulated
realized   gains   (losses)  on  investments   and  foreign   currency   related
transactions--net and paid-in capital of $9,212,167 and $569,601,  respectively,
to reflect adoption of the statement.

(2.) Capital Share Transactions 

The Trust agreement  authorizes the issuance of an unlimited number of shares of
beneficial  interest  with a par value of $1.00.  Transactions  in shares of the
Fund were as follows:

                                  Year Ended           Year Ended 
                                July 31, 1994        July 31, 1993 
Shares sold                        79,109,683          63,295,616 
Shares redeemed                  (114,282,869)        (61,949,194) 
Shares issued in 
  reinvestment of 
  distributions from: 
  investment income--net 
  and in excess of 
  investment income--net           9,447,901          10,663,481 
Net increase (decrease)           (25,725,285)         12,009,903 

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. 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 4% 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 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.

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 calendar quarter  (approximately  1.25% annually) occurring after
the inception of the  Distribution  Plan. 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 new 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).

The Fund has operated its Distribution Plan in accordance with both the Plan and
the NASD Rule since July 8, 1992, except that until July 7, 1993, maximum annual
payments with respect to Net Asset Value as  represented by shares sold prior to
January  1,  1992  remained  at the  then  current  rate  of  0.3125%  quarterly
(approximately 1.25% annually).

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  payment of such  charges from the Fund
(together  with annual  interest  thereon at the prime rate plus one percent) at
such time in the future as, and to the extent that,  payment thereof by the Fund
would be within  permitted  limits.  KDI  currently  intends to seek  payment of
interest only on such charges paid or accrued by KDI since January 1, 1992.

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 year ended July 31, 1994, the Fund  recovered  $179,947 in contingent
deferred sales charges.  During the year, the Fund paid KDI $9,079,585 under the
Distribution  Plan,  of  which  $1,339,027   represented  repayment  of  amounts
("advances")  paid by KDI  during  the year or in  previous  years in  excess of
amounts received by KDI under the Distribution Plan. The amount paid by the Fund
under its  Distribution  Plan, net of contingent  deferred  sales  charges,  was
$8,899,638 (0.96% of the Fund's average daily net asset value). During the year,
KDI retained  $4,485,981 and paid  commissions on new sales and maintenance fees
to dealers and others of $6,745,355,  of which $2,151,751 was an advance. During
the year, KDI received $1,014,043 in contingent deferred sales charges, reducing
the total advances  outstanding  to  $10,565,436  (1.38% of the Fund's net asset
value as of July 31, 1994). The right to certain portions of this amount, if and
when  receivable,  was  assigned by KDI in 1988 in  connection  with a financial
transaction.  As of July 31, 1994,  $7,396,647 of the amount  assigned  remained
outstanding.

(3.) Securities Transactions 

As of July 31, 1994,  the Fund had a capital loss  carryover for federal  income
tax purposes of  approximately  $411,209,000  which  expires as follows:  1996--
$17,290,000;  1997--$43,981,000;  1998-- $93,048,000;  1999--$91,149,000; 2000--
$122,350,000; and 2002--$43,391,000. For the year ended July 31, 1994, purchases
and sales of investment securities were as follows:

                                  Cost of            Proceeds 
                                 Purchases          from Sales 
Portfolio securities          $  969,258,277      $1,280,552,574 
Short-term investments         5,205,104,554       5,171,854,752 
                              $6,174,362,831      $6,452,407,326 

(4.) Investment Management and Transactions with Affiliates 

Under the terms of the Investment Management Agreement between KMI and the Fund,
dated December 29, 1989, KMI provides  investment  management and administrative
services to the Fund. In return,  KMI is paid a management fee computed and paid
daily and is based  upon both Fund net  assets  and gross  income  earned by the
Fund.  The fee is  calculated  at a rate of 2.0% of the Fund's gross  investment
income plus an amount  determined by applying  percentage  rates,  that start at
0.50% and decline,  as net assets  increase to 0.25% per annum, to the net asset
value of the Fund.  KMI has entered into an Investment  Advisory  Agreement with
Keystone,  dated  December 30, 1989,  under which Keystone  provides  investment
advisory  and  management  services to the Fund and receives for its services an
annual fee  representing  85% of the management fee received by KMI.  During the
year ended July 31, 1994, the Fund paid or accrued to KMI investment  management
and  administrative  services fees of $4,829,247 which  represented 0.52% of the
Fund's  average net assets.  Of such amount paid to KMI,  $4,104,859 was paid to
Keystone for its services to the Fund.

During the year ended  July 31,  1994,  the Fund paid or accrued to KIRC and KGI
$20,922 for certain accounting services and $2,391,954 for transfer agent fees.

(5.) Distributions to Shareholders 

A distribution of net investment  income of $.105 per share was declared payable
by  September  7,  1994 to  shareholders  of record on  August  25,  1994.  This
distribution is not reflected in the accompanying financial statements.

INDEPENDENT AUDITORS' REPORT

The Trustees and Shareholders 
Keystone Custodian Fund, Series B-4 

We have audited the accompanying statement of assets and liabilities of Keystone
Custodian Fund,  Series B-4,  including the schedule of investments,  as of July
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 July
31,  1994 by  correspondence  with the  custodian  and  brokers.  An audit  also
includes assessing the accounting principles used and significant estimates made
by  management,   as  well  as  evaluating  the  overall   financial   statement
presentation.  We believe  that our audits  provide a  reasonable  basis for our
opinion.

In our opinion,  the financial  statements and financial  highlights referred to
above  present  fairly,  in all material  respects,  the  financial  position of
Keystone  Custodian  Fund,  Series B-4, as of July 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.
