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

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

- ------------------------------------------------------------------------------
INVESTMENT OBJECTIVE AND POLICIES
- ------------------------------------------------------------------------------
INVESTMENT OBJECTIVE
     The Fund's investment objective is to provide shareholders with the highest
possible current income, exempt from federal income taxes, while preserving
capital.

     Since the Fund considers preservation of capital as well as the level of
tax exempt income, the Fund may realize less income than a fund willing to
expose shareholders' capital to greater risk.

     The investment objective of the Fund is fundamental and may not be changed
without the vote of a majority of the Fund's outstanding shares (as defined in
the 1940 Act).

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

PRINCIPAL INVESTMENTS AND INVESTMENT POLICIES
     Under ordinary circumstances, the Fund invests substantially all and at
least 80% of its assets in federally tax-exempt obligations. These obligations
include municipal bonds and notes and tax-exempt commercial paper obligations
that are issued by or on behalf of states, territories and possessions of the
United States ("U.S."), the District of Columbia and their political
subdivisions, agencies and instrumentalities, the interest from which is, in the
opinion of counsel to the issuers of such bonds, exempt from federal income
taxes, including the alternative minimum tax.

     Municipal bonds include debt obligations issued by or on behalf of a
political subdivision of the U.S. or any agency or instrumentality thereof to
obtain funds for various public purposes. In addition, municipal bonds include
certain types of industrial development bonds issued by or on behalf of public
authorities to finance privately operated facilities.

     The two principal classifications of municipal bonds are "general
obligation" and "limited obligation" or "revenue" bonds. General obligation
bonds involve the credit of an issuer possessing taxing power and are payable
from the issuer's general unrestricted revenues and not from any particular fund
or revenue source. Their payment may be dependent upon an appropriation by the
issuer's legislative body and may be subject to quantitative limitations on the
issuer's taxing power. Limited obligation or revenue bonds are payable only from
the revenues of a particular facility or class of facilities or, in some cases,
from the proceeds of a special excise or other specific revenue source, such as
the user of the facility.

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

     The Fund invests in municipal bonds only if, at the date of investment,
they are rated within the four highest grades by Standard & Poor's Corporation
("S&P") (AAA, AA, A and BBB), by Moody's Investors Service ("Moody's") (Aaa, Aa,
A and Baa) or by Fitch Investors Service, Inc. -- Municipal Division ("Fitch")
(AAA, AA, A and BBB) or, if not rated, are of comparable quality to obligations
so rated as determined by Keystone.

     However, Keystone expects that, under normal circumstances, at least 65% of
the Fund's total assets invested in municipal bonds will be within the three
highest ratings of such services or, if not rated, will be of comparable
quality.

     Debt rated BBB by S&P is regarded as having an adequate capacity to pay
interest and repay principal. While it normally exhibits adequate protection
parameters, adverse economic conditions or changing circumstances are generally
more likely to lead to a weakened capacity to pay interest and repay principal
for debt in this category than in high rated categories.

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

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

OTHER ELIGIBLE SECURITIES
     The Fund also may invest in securities that pay interest that is not exempt
from federal income taxes, such as corporate and bank obligations, obligations
issued or guaranteed by the U.S. government or by any of its agencies or
instrumentalities, commercial paper and repurchase agreements. Such securities
must be rated at least BBB by S&P or Baa by Moody's or, if not rated, must be
determined by Keystone to be of comparable quality. The Fund will not invest
more than 20% of its total assets under ordinary circumstances and up to 100% of
its total assets for temporary or defensive purposes in such securities.

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

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

     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
objective, policies and restrictions as the Fund. The Fund does not currently
intend to implement this policy and would do so only if the Trustees were to
determine such action to be in the best interest of the Fund and its
shareholders. In the event of such implementation, the Fund will comply with
such requirements as to written notice to shareholders as are then in effect.

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

- ------------------------------------------------------------------------------
INVESTMENT RESTRICTIONS
- ------------------------------------------------------------------------------
     The Fund has adopted the fundamental restrictions summarized below, which
may not be changed without the approval of a majority of the Fund's outstanding
shares (as defined in the 1940 Act). These restrictions and certain other
fundamental and nonfundamental restrictions are set forth in detail in the
statement of additional information.

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

- ------------------------------------------------------------------------------
RISK FACTORS
- ------------------------------------------------------------------------------
GENERAL
     Like any investment, your investment in the Fund involves an element of
risk. Before you invest in the Fund, you should carefully evaluate your ability
to assume the risks your investment in the Fund poses.

  Certain risks related to the Fund are discussed below. To the extent not
discussed in this section, specific risks attendant to individual securities or
investment practices are discussed in "Additional Investment Information."

FUND RISKS
     Investing in the Fund involves the risk common to investing in any
security, that is the value of the securities held by the Fund will fluctuate in
response to changes in economic conditions or public expectations about those
securities. For example, the market value of fixed income securities in which
the Fund may invest are likely to vary inversely to changes in prevailing
interest rates. In addition, the net asset value of the Fund's shares will
change according to the market's perception of the underlying portfolio
securities of the Fund.

     Should the Fund need to raise cash to meet a large number of redemptions,
it might have to sell portfolio securities at a time when it would be
disadvantageous to do so.

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

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

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

- ------------------------------------------------------------------------------
PRICING SHARES
- ------------------------------------------------------------------------------

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

     The Fund values municipal bonds on the basis of valuations provided by a
pricing service. The Fund's pricing service determines the value of such
municipal bonds using information with respect to transactions in bonds,
quotations from bond dealers, market transactions in comparable securities and
various relationships between securities. The Fund's pricing service has been
approved by its Board of Trustees.

     The Fund values short-term instruments with maturities of sixty days or
less at amortized cost (original purchase cost as adjusted for amortization of
premium or accretion of discount), which, when combined with accrued interest,
approximates market. Short-term instruments maturing in more than sixty days for
which market quotations are readily available are valued at current market
value. Short-term instruments maturing in more than sixty days when purchased
that are held on the sixtieth day prior to maturity are valued at amortized cost
(market value on the sixtieth day adjusted for amortization of premium or
accretion of discount), which, when combined with accrued interest, approximates
market and which, in any case, reflects fair value as determined by the Fund's
Board of Trustees. All other investments are valued at market value or, where
market quotations are not readily available, at fair value as determined in good
faith using methods prescribed by the Fund's Board of Trustees.

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

     The Fund has qualified and intends to continue to qualify as a regulated
investment company under the Code. The Fund qualifies if, among other things, it
distributes to its shareholders at least 90% of its net investment income for
its fiscal year. The Fund also intends to make timely distributions, if
necessary, sufficient in amount to avoid the nondeductible 4% excise tax imposed
on a regulated investment company to the extent that it fails to distribute,
with respect to each calendar year, at least 98% of its ordinary income for such
calendar year and 98% of its net capital gains for the one-year period ending on
October 31 of such calendar year. 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 distributes its net investment income to shareholders daily and
net realized long-term capital gains annually. Distributions are payable in
shares or, at the shareholder's option, (which must be exercised before the
record date for the distribution) in cash. Fund distributions in the form of
additional shares are made at net asset value without the imposition of a sales
charge.

     Any taxable dividend declared in October, November, or December to
shareholders of record in such a month and paid by the following January 31 will
be includable in the taxable income of the shareholders as if paid on December
31 of the year in which the dividend was declared.

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

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

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

     Some or all of the Fund's exempt interest dividends may be subject to state
income taxes. The Fund will report to shareholders on a state by state basis the
sources of its exempt interest dividends. Under particularly unusual
circumstances, such as when the Fund is in a prolonged defensive investment
position, it is possible that no portion of the Fund's distributions of income
to its shareholders for a fiscal year would be exempt from federal income tax;
however, the Fund does not presently anticipate that such unusual circumstances
will occur.

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

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

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

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

and (2) an amount equal to the amount of reimbursable expenses of Keystone
Management accrued during such calendar month.

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

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

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

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

     For the fiscal year ended December 31, 1995, the Fund paid or accrued to
Keystone Management investment management fees of $5,327,202, which represented
0.44% of the Fund's average net assets. Of such amount paid to Keystone
Management, $4,528,122 was paid to Keystone for its services to the Fund. In
addition, the Fund reimbursed Keystone Management $736,118, which represented
0.06% of the Fund's average net assets, in connection with reimbursable expenses
paid by Keystone Management on behalf of the Fund under the Management
Agreement. For the fiscal year ended December 31, 1995, the total fee paid to
Keystone Management by the Fund for investment management and administrative
services fees was $6,063,320, which represented 0.50% of the Fund's average net
assets.

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

FUND EXPENSES
     In addition to the investment advisory and management fees discussed above,
the principal expenses that the Fund is expected to pay include, but are not
limited to: expenses of its transfer agent, its custodian and its independent
auditors; expenses under its Distribution Plan; fees of its Trustees who are not
interested persons of the Fund, as defined in the 1940 Act (the "Independent
Trustees"); expenses of shareholders' and Trustees' meetings; fees payable to
government agencies, including registration and qualification fees of the Fund
and its shares under federal and state securities laws; expenses of preparing,
printing and mailing Fund prospectuses, notices, reports and proxy material; and
certain extraordinary expenses. In addition to such expenses, the Fund pays its
brokerage commissions, interest charges and taxes. For the fiscal year ended
December 31, 1995, the Fund paid 0.95% of its average net assets in expenses.

     During the fiscal year ended December 31, 1995, the Fund paid or accrued to
Keystone Investments $21,661 for certain accounting services and $1,433,700 to
Keystone Investor Resource Center, Inc. ("KIRC"), the Fund's transfer and
dividend disbursing agent, for certain shareholder services.

Keystone Senior Vice President and Senior Portfolio Manager and has more than 17
years of investment experience.

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

PORTFOLIO TURNOVER
     The Fund's portfolio turnover rates for the fiscal years ended December 31,
1995 and 1994 were 56% and 84%, respectively. For further information about

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

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

     In addition, you may open an account for the purchase of shares of the Fund
by mailing to the Fund, c/o Keystone Investor Resource Center, Inc., P.O. Box
2121, Boston, Massachusetts 02106-2121, a completed account application and a
check payable to the Fund. You may also call 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 investment in the Fund's
shares 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 the Fund receives the purchase order. The initial purchase must be at
least $1,000. 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 deferred sales charge may be imposed at rates
ranging from a maximum of 4% of amounts redeemed during the calendar year of
purchase to 1% of amounts redeemed during the third calendar year after the year
of purchase. No deferred sales charge is imposed on amounts redeemed thereafter
or on shares purchased through reinvestment of dividends and distributions. If
imposed, the deferred sales charge is deducted from the redemption proceeds
otherwise payable to the shareholder. To the extent permitted by NASD rules, the
deferred sales charge is paid to the Principal Underwriter.

     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. In determining whether a contingent deferred sales charge is
payable and, if so, the percentage charge applicable, it is assumed that shares
held the longest are the first to be redeemed.

     There is no deferred sales charge imposed on permitted exchanges of shares
between funds in the Keystone Fund Family that have adopted distribution plans
pursuant to Rule 12b-1 under the 1940 Act. 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 purchase of the shares
being exchanged is deemed to be the year shares being acquired by exchange were
originally purchased.

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

WAIVER OF DEFERRED SALES CHARGE
     Shares also may be sold, to the extent permitted by applicable law, at net
asset value without the payment of commissions or the imposition of a deferred
sales charge to (1) certain Directors, Trustees, officers, and employees of the
Fund, Keystone Management, Keystone and certain of their affiliates; (2)
registered representatives of firms with dealer agreements with the Principal
Underwriter; and (3) a bank or trust company acting as trustee for a single
account. For more details, see the statement of additional information.

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

     The Fund bears some of the costs of selling its shares under a Distribution
Plan adopted 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
service fees. The NASD also limits the aggregate amount that the Fund may pay
for such distribution costs to 6.25% of gross share sales since the inception of
the Fund's Distribution Plan, plus interest at the prime rate plus 1% on such
amounts (less any contingent deferred sales charges paid by shareholders to the
Principal Underwriter) remaining unpaid from time to time.

     Payments under the Distribution Plan are currently made to the Principal
Underwriter (which may reallow all or part to others, such as dealers) (1) as
commissions for Fund shares sold and (2) as shareholder service fees of respect
to shares maintained by the recipients on the Fund's books for specified
periods. Amounts paid or accrued to the Principal Underwriter under (1) and (2)
in the aggregate may not exceed the annual limitations referred to above. The
Principal Underwriter generally reallows to brokers or others a commission equal
to 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 on the books of the Fund for specified periods.

     If the Fund is unable to pay the Principal Underwriter a commission on a
new sale because the annual maximum (0.75% of average daily net assets) has been
reached, the Principal Underwriter intends, but is not obligated, to continue to
accept new orders for the purchase of Fund shares and to pay or accrue
commissions and service fees to dealers in excess of the amount it currently
receives from the Fund. While the Fund is under no contractual obligation to pay
the Principal Underwriter for advances made by the Principal Underwriter in
excess of the Distribution Plan limitation, the Principal Underwriter intends to
seek full payment of such charges from the Fund (together with interest at the
rate of prime plus 1%) at such time in the future as, and to the extent that,
payment thereof by the Fund would be within permitted limits. The Principal
Underwriter currently intends to seek payment of interest only on such charges
paid or accrued by the Principal Underwriter subsequent to July 7, 1992. If the
Fund's Independent Trustees authorize such payments, the effect would be to
extend the period of time during which the Fund incurs the maximum amount of
costs allowed by the Distribution Plan. If the Distribution Plan is terminated,
the Principal Underwriter will ask the Independent Trustees to take whatever
action they deem appropriate under the circumstances with respect to payment of
such amounts.

     During the fiscal year ended December 31, 1995, the Fund recovered $684,386
in contingentdeferred sales charges. During the same year, the Fund paid the
Principal Underwriter $4,719,697 under the Distribution Plan. The amount paid by
the Fund under its Distribution Plan, net of contingent deferred sales charges,
was $4,035,311. During the same year, the Principal Underwriter paid commissions
on new sales and service fees to dealers and others of $3,962,258.

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

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

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

ARRANGEMENTS WITH BROKER-DEALERS AND OTHERS
     Upon written notice to dealers, the Principal Underwriter may at its own
expense periodically sponsor programs which offer additional compensation in
connection with sales of Fund shares. Participation in such programs may be
available to all dealers or to selected dealers who have sold or are expected to
sell significant amounts of Fund shares. Additional compensation may also
include financial assistance to dealers in connection with preapproved seminars,
conferences and advertising. No such programs or additional compensation will be
offered to the extent they are prohibited by the laws of any state or any
self-regulatory agency, such as the NASD.

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

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

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

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

- ------------------------------------------------------------------------------
HOW TO REDEEM SHARES
- ------------------------------------------------------------------------------
REDEMPTION OF SHARES IN GENERAL
     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 redemption value equals 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 computes the redemption value at the close of the Exchange at the end
of the day on which it has received all proper documentation from the
shareholder. Payment of the amount due on redemption, less any applicable
deferred sales charge, will be made within seven days thereafter, except as
discussed herein.

     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.

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

     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 drawn on a U.S. bank or by bank wire of funds. Although the
mailing of a redemption check or the wiring of redemption proceeds may be
delayed, the redemption value will be determined and the redemption processed in
the ordinary course of business upon receipt of proper documentation. In such a
case, after redemption and prior to the release of the proceeds, no appreciation
or depreciation will occur in the value of the redeemed shares, and no interest
will be paid on the redemption proceeds. If the mailing of a redemption check
has been delayed, the check will be mailed promptly after good payment has been
collected.

     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.

     For the protection of shareholders, SIGNATURES ON CERTIFICATES, STOCK
POWERS AND ALL WRITTEN ORDERS OR AUTHORIZATIONS MUST BE GUARANTEED BY A U.S.
STOCK EXCHANGE MEMBER, A BANK OR OTHER PERSONS ELIGIBLE TO GUARANTEE SIGNATURES
UNDER THE SECURITIES EXCHANGE ACT OF 1934 AND KIRC'S POLICIES. The Fund and KIRC
may not only 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.

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

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

     If 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 redemptions 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 the Principal
Underwriter assumes responsibility for the authenticity of any instructions
received by any of them from a shareholder in writing, over KARL or by
telephone. KIRC will employ reasonable procedures to confirm that instructions
received over KARL or by telephone are genuine. Neither the Fund, KIRC nor the
Principal Underwriter will be liable when following instructions received over
KARL or by telephone that KIRC reasonably believes to be genuine.

     The Fund may temporarily suspend the right to redeem its shares when (1)
the Exchange is closed, other than customary weekend and holiday closings; (2)
trading on the Exchange is restricted; (3) 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
     KARL 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. You may access KARL by dialing
toll-free 1-800-346-3858 on any touch-tone telephone, 24 hours a day, seven days
a week.

EXCHANGES
     A shareholder who has obtained the appropriate prospectus may exchange
shares of the Fund for shares of any of the other funds in the Keystone Fund
Family, 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. (See "How to Redeem Shares" for additional information on telephone
transactions.)

     Fund shares purchased by check may be exchanged for shares of any fund in
the Keystone Fund Family other than Keystone Precious Metal Holdings, Inc.
("KPMH"), 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, a
shareholder must have held Fund shares for a period of at least six months. You
may exchange your shares for another Keystone fund for a $10 fee by calling or
writing to Keystone. The exchange fee will be waived for individual investors
who make an exchange using KARL. If the shares being tendered for exchange have
been held for less than four years and are still subject to a deferred sales
charge, such charge will carry over to the shares being acquired in the exchange
transaction. The Fund reserves the right, after 60 days' notice to shareholders,
to terminate this exchange offer or to change its terms, including the right to
change the fee for any exchange.

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

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

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

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

AUTOMATIC 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.

SYSTEMATIC INCOME PLAN
     Under a Systematic Income 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 Systematic Income
Plan is opened. Fixed withdrawal payments are not subject to a deferred sales
charge. Excessive withdrawals may decrease or deplete the value of a
shareholder's account.

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

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

     Current yield quotations represent the yield on an investment for a stated
30-day period computed by dividing net investment income earned per share during
the base period by the maximum offering price per share on the last day of the
base period.

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

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

- ------------------------------------------------------------------------------
FUND SHARES
- ------------------------------------------------------------------------------
     The Fund currently issues one class of shares, which participate equally in
dividends and distributions and have equal voting, liquidation and other rights.
When issued and paid for, the shares will be fully paid and nonassessable by the
Fund. Shares may be exchanged as explained under "Shareholder Services," but
will have no other preference, conversion, exchange or preemptive rights.
Shareholders of the Fund 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.

     The Fund does not hold annual meetings. The Fund will have special meetings
from time to time as required under its Declaration of Trust and under the 1940
Act. As provided in the Fund's Declaration of Trust, shareholders have the right
to remove Trustees by an affirmative vote of two-thirds of the outstanding
shares. A special meeting of the shareholders will be held when holders of 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.

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

                      ADDITIONAL INVESTMENT INFORMATION

CORPORATE AND MUNICIPAL BOND RATINGS

S&P CORPORATE AND MUNICIPAL BOND RATINGS

A.  MUNICIPAL NOTES

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

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

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

     Note ratings are as follows:

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

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

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

B.  TAX EXEMPT DEMAND BONDS

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

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

C.  CORPORATE AND MUNICIPAL BOND RATINGS

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

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

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

     2. nature of and provisions of the obligation; and

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

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

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

D.  BOND RATINGS

     Bond ratings are as follows:

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

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

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

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

MOODY'S CORPORATE AND MUNICIPAL BOND RATINGS
A.  MUNICIPAL NOTES

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

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

     The note ratings are as follows:

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

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

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

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

B.  CORPORATE AND MUNICIPAL BOND RATINGS

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

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

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

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

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

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

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

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

     The note ratings are as follows:

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

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

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

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

B.  CORPORATE AND MUNICIPAL BOND RATINGS

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

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

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

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

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

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

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

DESCRIPTIONS OF CERTAIN TYPES OF INVESTMENTS AND INVESTMENT TECHNIQUES
AVAILABLE TO THE FUND
     The Fund may engage in the following investment practices to the extent
described in the prospectus and statement of additional information.

OBLIGATIONS OF FOREIGN BRANCHES OF UNITED STATES BANKS

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

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

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

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

REVERSE REPURCHASE AGREEMENTS
     Under a reverse repurchase agreement, the Fund would sell securities and
agree to repurchase them at a mutually agreed upon date and price. The Fund
intends to enter into reverse repurchase agreements to avoid otherwise having to
sell securities during unfavorable market conditions in order to meet
redemptions. At the time the Fund enters into a reverse repurchase agreement, it
will establish a segregated account with the Fund's custodian containing liquid
assets such as U.S. government securities or other high grade debt securities
having a value not less than the repurchase price (including accrued interest)
and will subsequently monitor the account to ensure such value is maintained.
Reverse repurchase agreements involve the risk that the market value of the
securities that the Fund is obligated to repurchase may decline below the
repurchase price. Borrowing and reverse repurchase agreements magnify the
potential for gain or loss on the portfolio securities of the Fund and,
therefore, increase the possibility of fluctuation in the Fund's net asset
value. Such practices may constitute leveraging. In the event the buyer of
securities under a reverse repurchase agreement files for bankruptcy or becomes
insolvent, such buyer or its trustee or receiver may receive an extension of
time to determine whether to enforce the Fund's obligation to repurchase the
securities and the Fund's use of the proceeds of the reverse repurchase
agreement may effectively be restricted pending such determination. The staff of
the Securities and Exchange Commission ("SEC") has taken the position that a
fully secured or collateralized reverse repurchase agreement is not subject to
the percentage limit on borrowings imposed under Section 18 of the 1940 Act.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

     If permitted by its investment policies, 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.

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

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

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

                        INVESTMENT OBJECTIVE AND POLICIES
- --------------------------------------------------------------------------------
         The Fund is an open-end diversified management investment company. The
Fund's investment objective is to provide shareholders with the highest possible
current income, exempt from federal income taxes, while preserving capital.

         The Fund invests primarily in municipal bonds, but also may invest in
certain other securities as described in the Appendix hereto and the "Additional
Investment Information" section of the Fund's prospectus.

- --------------------------------------------------------------------------------
                             INVESTMENT RESTRICTIONS
- --------------------------------------------------------------------------------
         The Fund has adopted the fundamental investment restrictions set forth
below, which may not be changed without a vote of the holders of a majority of
the Fund's outstanding shares (as defined in the Investment Company Act of 1940
(the "1940 Act")). Unless otherwise stated, all references to the assets of the
Fund are in terms of current market value.

The Fund may not do the following:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

         (15) purchase securities of foreign issuers.

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

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


         Notwithstanding the eighth investment restriction enumerated above or
any of the other limitations above, the Fund may 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. See "Investment Objective and Policies" in the prospectus.

         Although not a fundamental restriction or policy requiring a
shareholders' vote to change, the Fund has undertaken to a state securities
authority that the Fund will not invest more than 15% of its total assets in the
securities of issuers, which together with any predecessors, have a record of
less than three years continuous operation or securities of issuers which are
restricted as to disposition.



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

         The Fund believes that reliable market quotations generally are not
readily available for purposes of valuing municipal bonds. As a result,
depending on the particular municipal bonds owned by the Fund, it is likely that
most of the valuations for such bonds will be based upon their fair value
determined under procedures that have been approved by the Fund's Board of
Trustees. The Fund's Board of Trustees has authorized the use of a pricing
service to determine the fair value of its municipal bonds and other securities.

         Non-tax exempt securities for which market quotations are readily
available are valued on a consistent basis at that price quoted that, in the
opinion of the Board of Trustees or the person designated by the Board of
Trustees to make the determination, most nearly represents the market value of
the particular security.

         Short-term investments that are purchased with maturities of sixty days
or less are valued at amortized cost (original purchase cost as adjusted for
amortization of premium or accretion of discount), which, when combined with
accrued interest, approximates market; short-term investments maturing in more
than sixty days for which market quotations are readily available are valued at
current market value; and short-term investments maturing in more than sixty
days when purchased that are held on the sixtieth day prior to maturity are
valued at amortized cost (market value on the sixtieth day adjusted for
amortization of premium or accretion of discount), which, when combined with
accrued interest, approximates market and which, in any case, reflects fair
value as determined by the Board of Trustees.

         Any securities for which market quotations are not readily available
are valued on a consistent basis at fair value as determined in good faith using
methods prescribed by the Fund's Board of Trustees.


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


         In order to reimburse the Fund for certain expenses relating to the
sale of its shares (see "Distribution Plan"), a 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. To the extent
permitted by National Association of Securities Dealers, Inc. ("NASD") rules,
the deferred sales charge attributable is paid to the Principal Underwriter.
Accordingly, for the fiscal year ended December 31, 1995, the Fund recovered
$684,386 and the Principal Underwriter received $95,377 in deferred sales
charges.


         The contingent deferred sales charge is a declining percentage of the
lesser of (1) the net asset value of the shares redeemed or (2) the total cost
of such shares. No contingent deferred sales charge is imposed when the
shareholder redeems amounts derived from (1) increases in the value of his
account above the total cost of such shares due to increases in the net asset
value per share of the Fund; (2) certain shares with respect to which the Fund
did not pay a commission on issuance, including shares acquired through
reinvestment of dividend income and capital gains distributions; or (3) shares
held in all or part of more than four consecutive calendar years.

         Subject to the limitations stated above, the Fund imposes the
contingent deferred sales charge according to the following schedule: 4% of
amounts redeemed during the calendar year of purchase; 3% of amounts redeemed
during the calendar year after the year of purchase; 2% of amounts redeemed
during the second calendar year after the year of purchase; and 1% of amounts
redeemed during the third calendar year after the year of purchase. No
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 1996 and on a given date in 1997 the value of
the investor's account has grown through investment performance and reinvestment
of distributions to $12,000. On such date in 1997, the investor could redeem up
to $2,000 ($12,000 minus $10,000) without incurring a deferred sales charge. If,
on such date, the investor should redeem $3,000, a deferred sales charge would
be imposed on $1,000 of the redemption (the amount by which the investor's
account was reduced by the redemption below the amount of the initial purchase
payment). The charge would be imposed at the rate of 3% because the redemption
is made during the calendar year after the calendar year of purchase, for a
total deferred sales charge of $30.


         In determining whether a contingent deferred sales charge is payable
and, if so, the percentage charge applicable, it is assumed that shares held the
longest are the first to be redeemed. There is no contingent deferred sales
charge on exchanges of shares between funds in the Keystone Fund Family 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 deferred sales charge, the calendar year
of purchase of the shares of the Fund exchanged into is deemed to be the year
shares being tendered for exchange were originally purchased.

         Shares also may be sold, to the extent permitted by applicable law,
regulations, interpretations or exemptions, at net asset value without the
imposition of a deferred sales charge upon redemption of shares by (1)
Directors, Trustees, officers, full-time employees and sales representatives of
the Keystone Management, Inc. ("Keystone Management"), Keystone Investment
Management Company (formerly known as Keystone Custodian Funds, Inc.)
("Keystone"), Keystone Investments, Inc. (formerly known as Keystone Group,
Inc.) ("Keystone Investments"), their subsidiaries and affiliates and the
Principal Underwriter who have been such for not less than ninety days; and (2)
the pension and profit-sharing plans established by such companies, their
subsidiaries and affiliates, for the benefit of their Directors, Trustees,
officers, full-time employees and sales representatives, provided, however, that
all such sales are made upon the written assurance of the purchaser that the
purchase is made for investment purposes and that the securities will not be
resold except through redemption by the Fund.

         No contingent deferred sales charge is imposed on a redemption of
shares of the Fund purchased by a bank or trust company in a single account in
the name of such bank or trust company as trustee, if the initial investment in
shares of the Fund, any other fund in the Keystone Fund Family, Keystone
Precious Metals Holdings, Inc., Keystone International Fund Inc., Keystone
Liquid Trust and/or any Keystone America Fund is at least $500,000 and any
commission paid by the Fund and such other funds at the time of such purchase is
not more than 1% of the amount invested.


         In addition, no contingent deferred sales charge is imposed on a
redemption of shares of the Fund in the event of (1) death or disability of the
shareholder; (2) 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 591/2 years old; (4) involuntary redemptions of accounts having an
aggregate net asset value of less than $1,000; (5) automatic withdrawals under
an automatic withdrawal plan of up to 11/2% per month of the shareholder's
initial account balance; (6) withdrawals consisting of loan proceeds to a
retirement plan participant; (7) financial hardship withdrawals made by a
retirement plan participant; or (8) withdrawals consisting of returns of excess
contributions or excess deferral amounts made to a retirement plan participant.

REDEMPTION OF SHARES

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

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

         Rule 12b-1 under the 1940 Act permits investment companies, such as the
Fund to use their assets to bear the 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 NASD also limits the aggregate amount that the
Fund may pay for such distribution costs to 6.25% of gross share sales since the
inception of the Fund's Distribution Plan plus interest at the prime rate plus
1% on such amounts (less any contingent deferred sales charge paid by
shareholders to the Principal Underwriter).


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

     If the Fund is unable to pay the Principal Underwriter a commission on a
new sale because the annual maximum (0.75% of average daily net assets) has been
reached, the Principal Underwriter intends, but is not obligated, to continue to
accept new orders for the purchase of Fund shares and to pay or accrue
commissions and service fees to dealers in excess of the amount it currently
receives from the Fund. While the Fund is under no contractual obligation to
reimburse the Principal Underwriter for advances made by the Principal
Underwriter in excess of the Distribution Plan limitation, the Principal
Underwriter intends to seek full payment of such amounts from the Fund, together
with interest at the prime rate plus 1%, at such time in the future as, and to
the extent that, payment thereof by the Fund would be within permitted limits.
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,
the Principal Underwriter will ask the Independent Trustees to take whatever
action they deem appropriate under the circumstances with respect to payment of
such amounts.

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

         The Distribution Plan may be terminated at any time by vote of the
Independent 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 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 will be required to
commit the selection and nomination of candidates for Independent Trustees to
the discretion of the Independent Trustees.

         During the fiscal year ended December 31, 1995, the Fund paid the
Principal Underwriter $4,719,697 under the Distribution Plan. For the same year,
the Principal Underwriter received $757,439, after payments of commissions on
new sales and service fees to dealers and others of $3,962,258.

         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.


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

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

DESCRIPTION OF SHARES

         The Declaration of Trust authorizes the issuance of an unlimited number
of shares of beneficial interest and the creation of additional series and/or
classes of series of Fund shares. 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.

SHAREHOLDER LIABILITY

         Pursuant to certain decisions of the Supreme Judicial Court of
Massachusetts, shareholders of a Massachusetts business trust may, under certain
circumstances, be held personally liable as partners for the obligations of the
Fund. If the Fund were held to be a partnership, the possibility of Fund
shareholders incurring financial loss for that reason appears remote because
the Declaration of Trust (1) contains an express disclaimer of shareholder
liability for obligations of the Fund; (2) 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 Declaration of Trust, 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 Declaration of Trust 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 meeting as described above, no further meetings of shareholders
for the purpose of electing Trustees will be held, unless required by law or
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
shareholder's 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 Declaration of Trust provides that a Trustee will not be liable for
errors of judgment or mistakes of fact or law, but nothing in the Declaration of
Trust protects a Trustee against any liability to which he would otherwise be
subject by any reason of willful misfeasance, bad faith, gross negligence or
reckless disregard of his duties involved in the conduct of his office.

         The Trustees have absolute and exclusive control over the management
and disposition of 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. As investment manager,
Keystone Management 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 funds in the Keystone Fund Family and to certain other funds in the
Keystone Investments Family of Funds.

         Except as otherwise noted below, pursuant to an Investment Management
Agreement with the Fund (the "Management Agreement") and subject to the
supervision of the Fund's Board of Trustees, Keystone Management manages and
administers the operation of the Fund and manages the investment and
reinvestment of the Fund's assets in conformity with the Fund's investment
objectives and restrictions. The Management Agreement stipulates that Keystone
Management shall provide office space and all necessary office facilities,
equipment and personnel in connection with its services under the Management
Agreement. The Management Agreement also stipulates that Keystone Management
shall pay or reimburse the Fund for the compensation of Fund officers and
Trustees who are affiliated with the investment manager and shall pay all
expenses of Keystone Management incurred in connection with the provision of its
services. All charges and expenses other than those specifically referred to as
being borne by Keystone Management will be paid by the Fund, including, but not
limited to, custodian charges and expenses; bookkeeping and auditors' charges
and expenses; transfer agent charges and expenses; fees of the Independent
Trustees; brokerage commissions, brokers' fees and expenses; issue and transfer
taxes; costs and expenses under the Distribution Plan; taxes and trust fees
payable to governmental agencies; the cost of share certificates; fees and
expenses of the registration and qualification of the Fund and its shares with
the Securities and Exchange Commission (sometimes referred to herein as the
"SEC" or the "Commission") or under state or other securities laws; expenses of
preparing, printing and mailing prospectuses, statements of additional
information, notices, reports and proxy materials to shareholders of the Fund;
expenses of shareholders' and Trustees' meetings; charges and expenses of legal
counsel for the Fund and for its Independent Trustees on matters relating to the
Fund; charges and expenses of filing annual and other reports with the SEC and
other authorities; and all extraordinary charges and expenses of the Fund;
provided, however, that Keystone Management pays all charges and expenses
relating to these items subject to reimbursement by the Fund.

         The Management Agreement permits Keystone Management to enter into an
agreement with Keystone or another investment adviser, under which Keystone or
such other investment adviser, as investment adviser, will provide substantially
all the services to be provided by Keystone Management under the Management
Agreement. The Management Agreement also permits Keystone Management to delegate
to Keystone or another investment adviser substantially all of the investment
manager's rights, duties and obligations under the Management Agreement.

         Services performed by Keystone Management include (1) performing
research and planning with respect to (a) the Fund's qualification as a
regulated investment company under Subchapter M of the Internal Revenue Code
(the "Code"), (b) tax treatment of the Fund's portfolio investments, (c) tax
treatment of special corporate actions (such as reorganizations), (d) state tax
matters affecting the Fund, and (e) the Fund's distributions of income and
capital gains; (2) preparing the Fund's federal and state tax returns; and (3)
providing services to the Fund's shareholders in connection with federal and
state taxation and distributions of income and capital gains.

         The Fund pays Keystone Management at the end of each calendar month a
fee for its services consisting of (1) an amount calculated as set forth below:

ANNUAL                                                      AGGREGATE NET
MANAGEMENT                                                  ASSET VALUE OF THE
FEE                                INCOME                   SHARES OF THE FUND
- --------------------------------------------------------------------------------
                             2.0% of Gross Dividend
                               and Interest Income
                                      Plus
0.50%    of the first                                       $100,000,000, plus
0.45%    of the next                                        $100,000,000, plus
0.40%    of the next                                        $100,000,000, plus
0.35%    of the next                                        $100,000,000, plus
0.30%    of the next                                        $100,000,000, plus
0.25%    of amounts over                                    $500,000,000; and

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

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

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

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

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

         The Management Agreement continues 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, by the Fund's Board of Trustees or by a vote of a majority of
outstanding shares on 60 days' written notice to Keystone, and by Keystone on 90
days' written notice to the Fund. The Management Agreement will terminate
automatically upon its "assignment," as that term is defined in the 1940 Act.

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


- --------------------------------------------------------------------------------
                               INVESTMENT ADVISER
- --------------------------------------------------------------------------------

         Pursuant to the Management Agreement, Keystone Management has delegated
its investment management functions, except for certain administrative and
management services, to Keystone and has entered into an Investment Advisory
Agreement with Keystone (the "Advisory Agreement") under which Keystone provides
investment advisory and management services to the Fund.

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

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

         Pursuant to a Principal Underwriting Agreement (the "Underwriting
Agreement"), Keystone Investment Distributors Company acts as the Fund's
principal underwriter. The Principal Underwriter, located at 200 Berkeley
Street, Boston, Massachusetts 02116-5034, is a Delaware corporation wholly-owned
by Keystone.

         The Principal Underwriter, as agent, currently has the right to obtain
subscriptions for and to sell shares of the Fund to the public. In so doing,
the Principal Underwriter may retain and employ representatives to promote
distribution of the Fund's shares and may obtain orders from brokers, dealers or
others, acting as principals, for sales of shares to them. No such
representative, dealer or broker has any authority to act as agent for the Fund.
The Principal Underwriter has not undertaken to buy or to fund purchasers for
any specific number of shares. The Principal Underwriter may receive payments
from the Fund pursuant to the Fund's Distribution Plan.

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

         The Underwriting Agreement provides that it will remain in effect as
long as its terms and continuance are approved by (1) a majority of the Fund's
Independent Trustees at least annually at a meeting called for that purpose and
(2) by vote of a majority of Trustees or by vote of a majority of the
outstanding shares.

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

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

         For the fiscal year ended December 31, 1993 the Principal Underwriter
earned commissions of $4,969,409 (amount represents commissions earned during
the fiscal year ended December 31, 1993 and excludes recapture by the Principal
Underwriter during said fiscal year of $4,272,087 in advances made during
previous fiscal years) after paying commissions of $3,705,342 (amount represents
sales commissions only and excludes $3,661,327 in maintenance fees paid during
the fiscal year) to retail dealers under the Distribution Plan.

         For the fiscal year ended December 31, 1994 the Principal Underwriter
earned commissions of $9,126,418 after paying commissions of $4,197,774 to
retail dealers under the Distribution Plan.

         During the fiscal year ended December 31, 1995, the Fund paid the
Principal Underwriter $4,719,697 under the Distribution Plan. The amount paid by
the Fund under its Distribution Plan, net of deferred sales charges, was
$4,035,311 (0.33% of the Fund's average daily net asset value during the
period). During the year, the Principal Underwriter received $757,439 after
payments of commissions on new sales and service fees to dealers and others of
$3,962,258. See the "Distribution Plan."

- --------------------------------------------------------------------------------
                                    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 broker's
ability to effect the transaction at all where a large block is involved; the
availability of the broker to stand ready to execute potentially difficult
transactions in the future; and the financial strength and stability of the
broker. Management weighs such considerations in determining the overall
reasonableness of brokerage commissions paid.

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

         The Fund expects that purchases and sales of municipal bonds and
temporary instruments usually will be principal transactions. Municipal bonds
and temporary instruments are normally purchased directly from the issuer or
from an underwriter or market maker for the securities. Accordingly, the Fund
does not usually pay brokerage commissions. Purchases from underwriters will
include the underwriting commission or concession, and purchases from dealers
serving as market makers will include a dealer's mark up or reflect a dealer's
mark down. Where transactions are made in the over-the-counter market, the Fund
will deal with primary market makers unless more favorable prices are otherwise
obtainable.

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

         Neither Keystone Management, Keystone nor the Fund intend to place
securities transactions with any particular broker-dealer or group thereof.
However, the Fund's Board of Trustees has determined that the Fund may consider
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 that is
equitable to each fund or account. It is recognized that in some cases this
system could have a detrimental effect on the price or volume of the security as
far as the Fund is concerned. In other cases, however, it is believed that the
ability of the Fund to participate in volume transactions will produce better
executions for the Fund.

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

         For the fiscal years ended December 31, 1993, 1994 and 1995, the Fund
did not pay any brokerage commissions for securities transactions.

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

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

         The cumulative total returns of the Fund for the one, five and ten
years ended December 31, 1995 were 13.61% (including contingent deferred sales
charge), 43.13% and 118.15%, respectively. The average annual total returns for
the one, five and ten year periods ended December 31, 1995 were 13.61%, 7.44%
and 8.11%, respectively.

         Current yield quotations as they may appear from time to time in
advertisements will consist of a quotation based on a 30-day period ended on the
date of the most recent balance sheet of the Fund, computed by dividing the net
investment income per share earned during the period by the maximum offering
price per share on the last day of the base period. The current yield for the
30-day period ended December 31, 1995 was 5.00%.

         Tax equivalent yield is, in general, the current yield divided by a
factor equal to one minus a stated income tax rate and reflects the yield a
taxable investment would have to achieve in order to equal on an after tax-basis
a tax exempt yield. The tax equivalent yield for an investor in the 31% federal
tax bracket for the 30-day period ended December 31, 1995 was 7.25%.


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

                                    APPENDIX
- --------------------------------------------------------------------------------

                                 MUNICIPAL BONDS

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

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

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

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

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

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

DESCRIPTION OF BOND RATINGS

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

                      CORPORATE AND MUNICIPAL BOND RATINGS

S&P CORPORATE AND MUNICIPAL BOND RATINGS

A. MUNICIPAL NOTES

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

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

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

         Note ratings are as follows:

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

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

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

B.  TAX EXEMPT DEMAND BONDS

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

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

C.  CORPORATE AND MUNICIPAL BOND RATINGS

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

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

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

         b. Nature of and provisions of the obligation; and

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

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

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

Bond ratings are as follows:

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

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

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

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

MOODY'S CORPORATE AND MUNICIPAL BOND RATINGS

         Moody's ratings are as follows:

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

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

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

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

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

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

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

                            MONEY MARKET INSTRUMENTS

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

COMMERCIAL PAPER RATINGS

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

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

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

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

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

UNITED STATES GOVERNMENT SECURITIES

         Securities issued or guaranteed by the U.S. 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 U.S. Government or its agencies
or instrumentalities include direct obligations of the U.S. Treasury and
securities issued or guaranteed by the Federal Housing Administration, Farmers
Home Administration, Export-Import Bank of the U.S., 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 U.S. Government agencies and instrumentalities,
such as Treasury bills and Government National Mortgage Association ("GNMA")
pass-through certificates, are supported by the full faith and credit of the
U.S.; 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 U.S. Government is not
obligated by law to provide support to an instrumentality it sponsors, the Fund
will invest in the securities issued by such an instrumentality only when
Keystone determines that the credit risk with respect to the instrumentality
does not make its securities unsuitable investments. U.S. Government securities
will not include international agencies or instrumentalities in which the U.S.
Government, its agencies or instrumentalities participate, such as the
International Bank for Reconstruction and Development (the "World Bank"), the
Asian Development Bank or the Inter-American Development Bank, or issues insured
by the Federal Deposit Insurance Corporation.

CERTIFICATES OF DEPOSITS

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

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

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

BANKERS' ACCEPTANCES

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

                              OPTIONS TRANSACTIONS

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

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

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

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

         Because the Fund intends to qualify as a regulated investment company
under the 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 that assumes responsibility for the completion of options
transactions.

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

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

         The Fund will not purchase a put option if, as a result of such
purchase, more than 10% of its total assets would be invested in premiums for
such options. The Fund's ability to purchase put and call options may be limited
by the 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 must purchase the underlying security from the buyer of the
put option at the exercise price, even though the price of the security may fall
below the exercise price, at any time during the option period. If an option
expires, the writer realizes a gain in the amount of the premium. Such a gain
may, in the case of a covered call option, be offset by a decline in the market
value of the underlying security during the option period. If a call option is
exercised, the writer realizes a gain or loss from the sale of the underlying
security. If a put option is exercised, the writer must fulfill his obligation
to purchase the underlying security at the exercise price, which will usually
exceed the then market value of the underlying security. In addition, the
premium paid for the put effectively increases the cost of the underlying
security, thus reducing the yield otherwise available from such securities.

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

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

OPTIONS TRADING MARKETS

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

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

SPECIAL CONSIDERATIONS APPLICABLE TO OPTIONS

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

         ON TREASURY BILLS. Because the deliverable U.S. Treasury bill changes
from week to week, writers of U.S. Treasury bills call options cannot provide in
advance for their potential exercise settlement obligations by acquiring and
holding the underlying security. However, if the Fund holds a long position in
U.S. Treasury bills with a principal amount corresponding to the option contract
size, the Fund may be hedged from a risk standpoint. In addition, the Fund will
maintain in a segregated account with its custodian able in the event of an
assignment of an exercise notice to ensure that it can meet its open option
obligations.

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

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

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

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

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

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

               FUTURES CONTRACTS AND RELATED OPTIONS TRANSACTIONS

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

         For example, a fund anticipates a significant market or market sector
advance, it will purchase a stock index futures contract as a hedge against not
participating in such advance at a time when 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, a fund would sell stock
index futures contracts in anticipation of or in a general market or market
sector decline that may adversely affect the market value of the fund's
portfolio. To the extent that the Fund's portfolio changes in value in
correlation with a given index, the sale of futures contracts on that index
would substantially reduce the risk to the portfolio of a market decline or
change in interest rates, and, by so doing, provide an alternative to the
liquidation of the Fund's securities positions and the resulting transaction
costs.

         The Fund intends to engage in options transactions that are related to
commodity futures contracts for hedging purposes and in connection with the
hedging strategies described above.

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

FUTURES CONTRACTS

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

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

INTEREST RATE FUTURES CONTRACTS

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

         Currently, interest rate futures contracts can be purchased or sold on
90-day U.S. Treasury bills, U.S. Treasury bonds, U.S. Treasury notes with
maturities between 6 1/2 and 10 years, certificates, 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 and U.S. Treasury
notes, 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, the futures contracts in U.S. government
securities are not obligations of the U.S. Treasury.

INDEX BASED FUTURES CONTRACTS

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

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

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

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

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

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

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

OPTIONS ON CURRENCY AND OTHER FINANCIAL FUTURES

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

         The Fund intends to use options on currency and other financial futures
contracts in connection with hedging strategies. In the future the Fund may use
such options for other purposes.

PURCHASE OF PUT OPTIONS ON FUTURES CONTRACTS

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

PURCHASE OF CALL OPTIONS ON FUTURES CONTRACTS

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

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

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

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

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

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

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

FEDERAL INCOME TAX TREATMENT

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

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

RISKS OF FUTURES CONTRACTS

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

         At best, the correlation between changes in prices of futures contracts
and of the securities being hedged can be only approximate. The degree of
imperfection of correlation depends upon circumstances, such as variations in
speculative market demand for futures contracts and for securities, including
technical influences in futures contracts trading; and differences between the
securities being hedged and the financial instruments and indexes underlying the
standard futures contracts available for trading, in such respects as interest
rate levels, maturities and creditworthiness of issuers, or identities of
securities comprising the index and those in the Fund's portfolio. A decision of
whether, when and how to hedge involves the exercise of skill and judgment, and
even a well-conceived hedge may be unsuccessful to some degree because of market
behavior or unexpected interest rate trends.

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

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

RISKS OF OPTIONS ON FUTURES CONTRACTS

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

                          FOREIGN CURRENCY TRANSACTIONS

         The Fund may invest in securities denominated in foreign currencies,
and the Fund temporarily may hold funds in foreign currencies. Thus, the Fund's
share value will be affected by changes in exchange rates.

FORWARD CURRENCY CONTRACTS

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

CURRENCY FUTURES CONTRACTS

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

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

FOREIGN CURRENCY OPTIONS TRANSACTIONS

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

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

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

PURCHASE OF PUT OPTIONS ON FOREIGN CURRENCIES

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

PURCHASE OF CALL OPTIONS ON FOREIGN CURRENCIES

         The purchase of a call option on foreign currency represents a means of
obtaining temporary exposure to market appreciation at limited risk. It is
analogous to the purchase of a call option on an individual stock which can be
used as a substitute for a position in the stock itself. Depending on the
pricing of the option compared to either the foreign currency upon which it is
based, or upon the price of the foreign stock or foreign debt instruments, the
purchase of a call option may be less risky than the ownership of the foreign
currency or the foreign securities. The Fund would purchase a call option on a
foreign currency to hedge against an increase in the foreign currency or a
foreign market advance when the Fund is not fully invested.

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

CURRENCY TRADING RISKS

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

EXCHANGE RATE RISK

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

MATURITY GAPS AND INTEREST RATE RISK

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

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

CREDIT RISK

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

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

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

COUNTRY RISK

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

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

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

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

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

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

NOTES TO FINANCIAL STATEMENTS

(1.) Significant Accounting Policies

Keystone Tax Free Fund (the "Fund") is a Massachusetts business trust for
which Keystone Management, Inc. ("KMI") is the Investment Manager and
Keystone Investment Management Company (formerly Keystone Custodian Funds,
Inc.) ("Keystone") is the Investment Adviser. The Fund is registered under
the Investment Company Act of 1940, as amended (the "1940 Act"). The Fund
seeks current income, exempt from federal income taxes, while preserving
capital by investing in high quality municipal bonds.

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

The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. The
policies are in conformity with generally accepted accounting principles
which requires management to make estimates and assumptions that affect
amounts reported herein. Although actual results could differ from these
estimates, any such differences are expected to be immaterial to the net
assets of the Fund.

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

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

B. The Fund may enter into futures contracts. A futures contract is an
agreement between two parties to buy and sell a specific amount of a
commodity, security, financial instrument, or, in the case of a stock index,
cash at a set price on a future date. Upon entering into a futures contract,
the Fund is required to deposit with a broker an amount ("initial margin")
equal to a certain percentage of the purchase price indicated in the futures
contract. Subsequent payments ("variation margin") are made or received by
the Fund each day, as the value of the underlying instrument or index
fluctuates, and are recorded for book purposes as unrealized gains or losses
by the Fund. For federal tax purposes, any futures contracts which remain
open at fiscal year-end are marked-to-market and the resultant net gain or
loss is included in federal taxable income. In addition to the market risk,
the Fund is subject to

<PAGE>

PAGE 26

Keystone Tax Free Fund

the credit risk that the other party will not be able to complete the
obligations of the contract.

C. 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.

D. Securities transactions are accounted for no later than the day following
the trade date. Realized gains and losses are recorded on the identified cost
basis. Interest income is recorded on the accrual basis. All premiums and
original issue discounts are amortized/ accreted for both financial reporting
and federal income tax purposes.

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

F. The Fund distributes net investment income monthly and capital gains, if
any, annually. Distributions are determined in accordance with income tax
regulations. The significant differences between financial statement amounts
available for distribution and distributions made in accordance with income
tax regulations are the differences in treatment of 12b-1 Distribution Plan
charges for financial statement and federal tax purposes.

(2.) Capital Share Transactions

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

</TABLE>
  The Fund bears some of the costs of selling its shares under a Distribution
Plan adopted pursuant to Rule 12b-1 under the 1940 Act. Under the
Distribution Plan, the Fund pays Keystone Investment Distributors Company
(formerly Keystone Distributors, Inc.) ("KIDC"),


PAGE 27

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 KIDC in connection
with the Distribution Plan, and subject to the limitations discussed below,
KIDC generally pays brokers or others a commission equal to 3.00% 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 4.00%, 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 1.00% of
which 0.75% may be used to pay such distribution expenses and 0.25% may be
used to pay shareholder service fees. The NASD Rule also limits the aggregate
amount which the Fund may pay for such distribution costs to 6.25% of gross
share sales since the inception of the Fund's Distribution Plan, plus
interest at the prime rate plus 1.00% on unpaid amounts thereof (less any
contingent deferred sales charges paid by the shareholders to KIDC).

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 KIDC rather than to the Fund. During the year, KIDC
received $95,377 in deferred sales charges.

KIDC intends, but is not obligated, to continue to pay or accrue distribution
charges which exceed current annual payments permitted to be received by KIDC
from the Fund. KIDC intends to seek full payment of such charges from the
Fund (together with annual interest thereon at the prime rate plus 1.00%) at
such time in the future as, and to the extent that, payment thereof by the
Fund would be within permitted limits. KIDC currently intends to seek payment
of interest only on such charges paid or accrued by KIDC since January 1,
1992.

During the year ended December 31, 1995, the Fund recovered $684,386 in
contingent deferred sales charges. During the year ended December 31, 1995,
the Fund paid KIDC $4,719,697 under the Distribution Plan. The amount paid by
the Fund under its Distribution Plan, net of deferred sales charges, was
$4,035,311 (1.00% of the Fund's average daily net assets). During the year
ended December 31, 1995, KIDC received $757,439, after payments of
commissions on new sales and service fees to dealers and others of
$3,962,258.

(3.) Securities Transactions

As of December 31, 1995, the Fund had a capital loss carryover for federal

<PAGE>

Keystone Tax Free Fund

income tax purposes of approximately $28,660,000 which expires as follows: 
$25,307,000 in 2002 and $3,353,000 in 2003.

For the year ended December 31, 1995, cost of purchases and proceeds from
sales of investment securities (excluding short-term securities) were
$657,975,531 and $789,712,237, respectively.

(4.) Investment Management Agreement and Other Transactions

Under the terms of the Investment Management Agreement between KMI and the
Fund, KMI provides investment management and administrative services to the
Fund. In return, KMI is paid a management fee computed and paid daily. The
management fee is calculated at an annual rate of 2.0% of the Fund's gross
investment income plus an amount determined by applying percentage rates,
starting at 0.50% and declining as net assets increase to 0.25% per annum, to
the net asset value of the Fund.

  KMI has entered into an Investment Advisory Agreement with Keystone under
which Keystone provides investment advisory and management services to the
Fund and receives for its services an annual fee representing 85% of the
management fee received by KMI.

  During the year ended December 31, 1995, the Fund paid or accrued a
management fee of $5,327,202 which represented 0.44% of the Fund's average
net assets. Of such amount paid to KMI, $4,528,122 was paid to Keystone for
its services to the Fund.

  Included in the administrative services fee paid by the Fund were the
following amounts incurred by KMI (and reimbursed by the Fund) in providing
or obtaining for the Fund additional operating services, facilities and
supplies: audit and legal--$77,500, custodian fees--$503,476, printing and
supplies-- $94,700, registration fees--$54,450, and other-- $5,992. In
addition during the year ended December 31, 1995, the Fund paid to KIRC
$1,433,700 for shareholder services. This amount for shareholder services is
included in the payments made by KMI.

  The Fund has entered into an expense offset arrangement with its custodian.
For the year ended December 31, 1995, the Fund paid custody fees in the
amount of $355,325 and received a credit of $148,151 pursuant to the expense
offset arrangement, resulting in a total expense of $503,476. The assets
deposited with the custodian under the expense offset arrangement could have
been invested in income-producing assets.

  For the year ended December 31, 1995, the Fund paid to KII $21,661 for
certain accounting services.

  Certain officers and/or Directors of Keystone are also officers and/or
Trustees of the Fund. Officers of Keystone and affiliated Trustees receive no
compensation directly from the Fund.
