                          KEYSTONE STATE TAX FREE FUND

March __, 1996


Dear Keystone Texas Tax Free Fund Shareholder:

We are writing to inform you of a proposal to effectively merge Keystone Texas
Tax Free Fund into Keystone Tax Free Income Fund. The Board of Trustees are
recommending this action because we believe it will result in improved operating
efficiencies and reduced operating expenses for your Keystone investment. The
proposed reorganization will be a tax-free transaction.

Keystone Tax Free Income Fund and Keystone Texas Tax Free Fund both pursue the
same investment objective, which is to provide the highest possible income
exempt from federal taxes while preserving capital. Keystone Tax Free Income
Fund is also managed by the same team of investment professionals as Keystone
Texas Tax Free Fund. Both Funds follow a similar investment strategy, the
principal difference being that Keystone Texas Tax Free Fund invests primarily
in Texas municipal bonds while Keystone Tax Free Income Fund has the flexibility
to invest in municipal bonds issued throughout the nation.

Keystone Texas Tax Free Fund has not grown sufficiently in size to achieve the
economies of scale that increasingly are necessary for successful mutual funds.
At the same time, it appears unlikely that Texas will enact a state income tax,
which would increase the viability of a state tax free fund in Texas.

We believe Keystone Tax Free Income Fund offers Keystone Texas Tax Free Fund
shareholders the following advantages:

(bullet) improved operating efficiencies;
(bullet) potential for lower operating expenses; and
(bullet) national diversification.

The Trustees of Keystone Texas Tax Free Fund have carefully reviewed this
proposal and believe it is in the best interest of shareholders. They recommend
that you vote FOR the proposal.

It is extremely important that you vote, no matter how many shares you own. This
is an opportunity to voice your opinion on a matter that affects your Fund.
Voting promptly helps to reduce the cost of additional mailings.

The accompanying Prospectus/Proxy Statement describes the proposal in detail.

To Vote Your Shares

A shareholder meeting has been scheduled for Tuesday, April 30, 1996, at 200
Berkeley Street, Boston, MA. You are welcome to attend this meeting. However, if

vote by completing the enclosed proxy card and returning it in the postage-paid

If you have any questions about this proposal, please call Keystone
Shareholder Services at 1-800-343-2898.  Our representatives are
available Monday through Friday from 9 a.m. to 7 p.m. Central time
and would be happy to answer your questions.

                           PROSPECTUS/PROXY STATEMENT

                                  March 4, 1996


                          Acquisition of the Assets of

                          KEYSTONE TEXAS TAX FREE FUND
                                 A Portfolio of
                          KEYSTONE STATE TAX FREE FUND
                200 Berkeley Street, Boston, Massachusetts 02116
                Telephone Number (800) 343-2898 or (617) 621-6100


                        By and in exchange for Shares of

                          KEYSTONE TAX FREE INCOME FUND
                200 Berkeley Street, Boston, Massachusetts 02116
                Telephone Number (800) 343-2898 or (617) 621-6100



         This Prospectus/Proxy Statement is being furnished to the shareholders
of Keystone Texas Tax Free Fund (the "Texas Fund"), a separate series or
portfolio of Keystone State Tax Free Fund ("KSTFF"), in connection with the
proposed tax-free reorganization of the Texas Fund into Keystone Tax Free Income
Fund ("KTFIF"), whereby KTFIF will (i) acquire all of the assets of the Texas
Fund in exchange for Class A, B, and C Shares (as said term is hereinafter
defined) of KTFIF; and (ii) assume the liabilities of the Texas Fund.
Immediately following this transfer, Class A, B, and C Shares of KTFIF will be
distributed to the Class A, B, and C shareholders of the Texas Fund,
respectively, in place of their Shares of the Texas Fund. The Texas Fund will
then be terminated and its Shares cancelled. As a result of the proposed
transaction, each class of shareholder of the Texas Fund will receive that
number of full and fractional Shares of the corresponding class of Shares of
KTFIF having a total net asset value, on the effective date of the proposed
transaction, equal to the total net asset value of that shareholder's Shares in
the Texas Fund.

         KTFIF is an open-end, diversified management investment company. KSTFF
is a open-end, non-diversified management investment company. The Texas Fund is
a non-diversified portfolio of KSTFF. Keystone Investment Management Company
("Keystone") serves as investment adviser to both Funds. Keystone Management,
Inc., a wholly-owned subsidiary of Keystone, provides certain administrative and
management services to KTFIF.

         Both Funds seek the highest possible current income exempt from federal
income taxes while preserving capital. KTFIF pursues this objective by investing
primarily in a relatively diverse pool

                                      - 1 -

<PAGE>

of municipal bonds, consisting of debt securities issued by or on behalf of a
number of different states, state agencies, or instrumentalities. In contrast,
the Texas Fund pursues the same objective by investing primarily in municipal
obligations of the State of Texas, its political subdivisions, agencies, and
instrumentalities. Texas does not impose an income tax on individuals.
Accordingly, unlike shareholders in other state municipal bond mutual funds
(such as mutual funds investing primarily in California or New York municipal
obligations), who are generally able to exclude their mutual fund earnings from
their state income taxes, shareholders in the Texas Fund have enjoyed no such
benefit. Consequently, the exchange of shares in the Texas Fund for shares in
KTFIF will not have any impact on the taxes an individual shareholder pays to
the State of Texas.

         This Prospectus/Proxy Statement sets forth concisely the information
about KTFIF that a prospective investor should know before investing and should
be retained for future reference. This Prospectus/Proxy Statement is accompanied
by the Prospectus of KTFIF dated March 31, 1995, as supplemented June 1, 1995,
which has been filed with the Securities and Exchange Commission (the
"Commission") and is incorporated by reference herein. Additional information
about KTFIF is contained in KTFIF's Statement of Additional Information ("SAI")
dated March 31, 1995, as supplemented June 1, 1995, and in an SAI dated March 4,
1996 relating specifically to the proposed transaction, each of which has been
filed with the Commission and is incorporated by reference herein. KTFIF's most
recent Annual Report as filed with the Commission is also incorporated by
reference herein.

         A Prospectus and SAI containing additional information about the Texas
Fund, each dated May 31, 1995, as supplemented June 1, 1995, have been filed
with the Commission and are incorporated by reference herein.

         Copies of any of the Prospectuses, SAIs, or Reports referred to above
may be obtained without charge by writing to KTFIF at the address listed above
or by calling the telephone numbers listed above.



THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.

                         Special Meeting of Shareholders
                            To be Held April 30, 1996



         This Prospectus/Proxy Statement is furnished to shareholders of
Keystone Texas Tax Free Fund (the "Texas Fund"), a separate series or portfolio
of Keystone State Tax Free Fund ("KSTFF"), in connection with the solicitation
of proxies by the Board of Trustees of KSTFF to be used at a special meeting of
the Texas Fund's shareholders (the "Meeting") to be held at the offices of
Keystone Investment Management Company, 200 Berkeley Street, Boston,
Massachusetts, on the 26th Floor, on Tuesday, April 30, 1996, at 3:00 p.m.
Eastern time. This document also serves as a prospectus of KTFIF and covers the
issuance of KTFIF Shares in connection with the proposed transaction.

         For any proxy that is properly executed and returned in time to be
voted at the Meeting, the Texas Fund Shares represented thereby will be voted in
accordance with the instructions thereon. In the absence of such instructions,
the proxy will be voted in favor of the approval of the Agreement and Plan of
Reorganization (the "Reorganization Agreement") and the transaction described
therein, whereby Keystone Tax Free Income Fund ("KTFIF") will (i) acquire all of
the assets of the Texas Fund in exchange for Shares of KTFIF; and (ii) assume
the liabilities of the Texas Fund.

         The individuals duly appointed as Proxies ("Proxies") may, in their
discretion, vote upon such other matters as may come before the Meeting or any
adjournments thereof. When voting proxies on a proposal to adjourn, the Proxies
will consider what is in the best interest of all shareholders at that time.

         Any shareholder may revoke his or her proxy at any time before it is
voted by delivering written notice of revocation or by executing and delivering
a later-dated proxy to Rosemary D. Van Antwerp, Keystone Investment Management
Company, 200 Berkeley Street, Boston, Massachusetts 02116, or by appearing in
person at the Meeting to vote his or her Shares.

         Each Texas Fund shareholder will be entitled to one vote for each Share
and a fractional vote for each fractional Share held by such shareholder.
Shareholders of the Texas Fund of record at the close of business on March 4,
1996 (the "Record Date") will be entitled to notice of and to vote at the
Meeting or any adjournment

                                      - 1 -

thereof.  On the Record Date, there were ___________ Shares of the
Texas Fund outstanding.

         Proxy material is expected to be mailed to the Texas Fund shareholders
on or about March 11, 1996.


VOTE REQUIRED

         Approval of the Reorganization Agreement will require the affirmative
vote of the holders of (i) 67% of the Shares represented at the Meeting, if the
holders of more than 50% of the outstanding Shares of the Texas Fund are
represented; or (ii) more than 50% of the Texas Fund's outstanding Shares,
whichever is less. Shareholders of KTFIF will not be voting on the approval of
the Reorganization Agreement since their approval is not required.

         Abstentions and broker "non-votes" will be counted for purposes of
determining a quorum, but will not be counted in determining approval of the
Reorganization Agreement. Broker "non-votes" are proxies from brokers or
nominees indicating that such persons have not received instructions from the
beneficial owner or other persons entitled to vote shares on a particular matter
with respect to which the brokers or nominees do not have discretionary power.

                                    SYNOPSIS


         The following is a summary of certain information contained in or
incorporated by reference in this Prospectus/Proxy Statement. This summary is
not intended to be a complete statement of all material features of the
Reorganization and is qualified in its entirety by reference to the full text of
this Prospectus/Proxy Statement and the documents referred to herein.

DESCRIPTION OF THE PROPOSED TRANSACTION

         The Board of Trustees of each Fund, including each Fund's Independent
Trustees, have unanimously approved the Reorganization Agreement, which provides
for the transfer of all of the assets of the Texas Fund to KTFIF in exchange for
Shares of KTFIF as well as the assumption of the Texas Fund's liabilities by
KTFIF.

         The aggregate net asset value of KTFIF Shares to be issued in exchange
for the assets of the Texas Fund will be equal to the net asset value of the
Texas Fund on the Effective Date. Immediately following the transfer of assets
and liabilities of the Texas Fund to KTFIF, Class A, B, and C Shares of KTFIF
will be distributed to the respective Class A, B, and C shareholders of the
Texas Fund, and the Texas Fund will be dissolved. The Texas Fund Shares will be
cancelled, and the Texas Fund will be terminated. Each shareholder in the Texas
Fund will receive that percentage of the total number of the corresponding class
of KTFIF Shares received by the Texas Fund equal in amount to that shareholder's
percentage interest in the Texas Fund on the Effective Date. For example, Class
A shareholders of the Texas Fund would receive Class A shares of KTFIF.

         The Reorganization will effectively combine the two Funds into a single
fund offering three classes of Shares.

         For the reasons set forth below in "The Reorganization Reasons for the
Proposed Transaction," the Board of Trustees of KSTFF, including the Independent
Trustees, has concluded that the Reorganization would be in the best interests
of the shareholders of the Texas Fund and has further determined that the
interests of the existing shareholders of the Texas Fund will not be diluted as
a result of the Reorganization.

         Accordingly, the Board of KSTFF recommends A VOTE FOR the approval of
the Reorganization.

Amounts shown in the example should not be considered a representation of past

* Please see footnotes following pro forma fee table.


         To summarize, for the fiscal year ended November 30, 1995, KTFIF's
Class A, B, and C Shares each paid 1.19%, 1.96%, and 1.96%, respectively, of
average daily net assets in expenses. After expense reimbursements made by
Keystone in connection with certain voluntary expense limitations, for the
fiscal year ended March 31, 1995, the Texas Fund's Class A, B, and C Shares each
paid 0.75%, 1.50%, and 1.50%, respectively, of average daily net assets in
expenses. Absent such voluntary expense limitations, expenses for the Texas
Fund's Class A, B, and C Shares would have been 2.57%, 3.36%, and 3.28%,
respectively .

         invested increases.

3        Purchases of Class A shares in the amount of $1,000,000 or more and/or
         purchases made by certain qualifying retirement or other plans are not
         subject to a sales charge, but may be subject to a contingent deferred
         sales charge.

4        There is no fee for exchange orders received by a Fund directly from a
         shareholder over the Keystone Automated Response Line.

5        Expense ratios for KTFIF are for the Fund's fiscal year ended November
         30, 1995. Expense ratios for the Texas Fund are for the Fund's fiscal
         year ended March 31, 1995 after giving effect to the reimbursement by
         Keystone of expenses in accordance with certain voluntary expense
         limitations. Currently, Keystone has voluntarily limited expenses of
         the Texas Fund's Class A, B, and C shares to 0.75%, 1.50%, and 1.50%
         (respectively) of average daily net assets of each such class. Keystone
         is under no obligation to maintain these limits. Keystone currently
         intends to continue the expense limits on a calendar month by month
         basis. Keystone will periodically evaluate the foregoing expense limits
         and may modify or terminate them in the future. Absent the voluntary
         expense limits, expense ratios for the fiscal year ended March 31, 1995
         for Texas Fund's Class A, B, and C shares would have been 2.57%, 3.36%,
         and 3.28%, respectively. The pro forma expense ratios for KTFIF after
         giving effect to the Reorganization are estimated for the Fund's fiscal
         year ending November 30, 1996. KTFIF Total Fund Operating Expenses
         include indirectly paid expenses.

6        Long term shareholders may pay more than the equivalent of the maximum
         front end sales charges permitted by the National Association of
         Securities Dealers, Inc. ("NASD").

7        The Securities and Exchange Commission requires use of a 5% annual
         return figure for purposes of this example. Actual return for the Fund
         may be greater or less than 5%.

Texas Fund Advisory Fees

         Keystone serves as the investment adviser to the Texas Fund. Pursuant
to an Investment Advisory and Management Agreement with KSTFF, Keystone provides
investment advisory and management services to the Texas Fund.

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

                                                Aggregate Net Asset
                                                Value of the Shares

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

         For the fiscal year ended March 31, 1995, the Texas Fund paid or
accrued to Keystone investment management and service fees of $25,402, which
represented 0.55% of the Texas Fund's average daily net assets.

         The Funds' investment advisory and management fees are
separate from and do not include the costs of custody, transfer
agency, and other expenses.  See "Other Significant Fees and
Expenses" below.


Other Significant Fees and Expenses

         In addition to the investment advisory and management fees described
above, each Fund's principal expenses include, but are not limited to, (i)
expenses of its transfer agent (KIRC), custodian bank (State Street Bank and
Trust Company ("State Street")), and independent auditors (KPMG Peat Marwick
LLP); (ii) expenses under its 12b-1 Plans; (iii) fees of its Independent
Trustees; (iv) fees payable to government agencies; (v) expenses of preparing,
printing, and mailing Fund prospectuses, notices, reports, and proxy material;
and (vi) certain extraordinary expenses. In addition to such expenses, each Fund
pays its brokerage commissions, interest charges, and taxes.

Performance Data

         The average annual total returns for the Texas Fund's Class A, B, and C
Shares for the fiscal year ended March 31, 1995 were 5.66%, 5.01%, and 5.14%,
respectively. Average annual total returns for KTFIF's Class A, B, and C Shares
for the fiscal year ended November 30, 1995 were 13.07%, 13.84%, and 17.84%,
respectively.


Investment Objectives and Policies

         The Funds have the same investment objective: each Fund seeks the
highest possible current income, exempt from federal income taxes, while
preserving capital. The Funds principally differ in that Keystone Tax Free
Income Fund, unlike the Texas Fund, does not seek to achieve its investment
objective by investing primarily in Texas municipal bonds.

         To achieve its investment objective, KTFIF generally invests in a
diverse portfolio of municipal bonds. More specifically, KTFIF invests
substantially all and, under ordinary circumstances, at least 80% of its assets
in federally tax-exempt obligations, including municipal bonds and notes and
tax-exempt commercial paper (municipal bonds), which are obligations issued by
or on behalf of states, territories, and possessions of the United States
("U.S."), the District of Columbia, and their political subdivisions, agencies,
and instrumentalities, the interest from which is, in the opinion of counsel to
the issuers of such bonds, exempt from federal income taxes.

         To achieve the same investment objective, the Texas Fund generally
invests in Texas municipal bonds. More specifically, under ordinary
circumstances, the Texas Fund invests substantially all and at least 80% of its
assets in municipal obligations of the State of Texas that are exempt from
federal income taxes. Such securities include debt obligations of the State of
Texas and its political subdivisions, agencies, authorities, and
instrumentalities. Unlike KTFIF, the Texas Fund is not "diversified" as that
term is defined under the 1940 Act.

         Texas does not currently impose an income tax on individuals.
Accordingly, the Texas Fund's emphasis on Texas municipal obligations does not
currently result in any tax savings on a state level to the Fund's individual
Texas shareholders.

         Generally speaking, KTFIF generates comparable tax advantages to those
currently enjoyed by the Texas Fund shareholders through its investment in a
significantly larger portfolio of securities, which is diversified across a
nationwide spectrum of issuers.



                                     - 12 -

<PAGE>



         In addition, each 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 (AAA, AA, A and BBB), by Moody's Investors Service, Inc.
(Aaa, Aa A and Baa), or by Fitch Investors Service, Inc. - Municipal Division
(AAA, AA, A and BBB), or, if not rated, are of comparable quality to obligations
so rated as determined by Keystone.

         Moreover, in furtherance of their investment objectives, both Funds may
use certain "derivative instruments," including structured securities.

         In summary, excepting the Texas Fund's strict geographic focus, both
Funds invest in the same kinds of securities and use the same types of
investment techniques.

         For a more complete discussion of the Funds' investment objectives,
policies, restrictions, permitted investments, and investment techniques, see
"Investment Restrictions" below, "Information About the Funds" and each Fund's
Prospectus and SAI.


Investment Restrictions

         Each of the Funds has certain fundamental investment restrictions that
may not be changed without the vote of a 1940 Act majority of the Fund's
outstanding voting shares. Except as noted below, KSTFF's and KTFIF's
fundamental investment restrictions are substantially the same. KTFIF differs
from KSTFF in that KTFIF is subject to the additional fundamental restrictions
set forth below.

         KTFIF may not:

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

         (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) pledge more than 15% of its net assets to secure indebtedness; the
purchase or sale of securities on a "when issued" basis, or collateral
arrangement with respect to the writing of options on securities, are not deemed
to be a pledge of assets; and



                                     - 13 -

<PAGE>



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

         For a more complete discussion of the Funds' investment restrictions,
see "Information About the Funds" and each Fund's Prospectus and SAI.


Purchase and Redemption Procedures, Deferred Sales Charges and
Exchange Rights

         Generally, each Fund offers three classes of shares:


Class A Shares - Front End Load Option

         Class A shares are sold with a sales charge at the time of purchase.
With certain exceptions, Class A shares are not subject to a deferred sales
charge when redeemed.

Class B Shares - Back End Load Option

         Class B shares are sold without a sales charge at the time of purchase,
but are, with certain exceptions, subject to a contingent deferred sales charge
when redeemed. Class B shares purchased on or after June 1, 1995 are subject to
a deferred sales charge upon redemption during the 72 month period commencing
from and including the month of purchase at rates ranging from a maximum of 5%
of amounts redeemed during the first 12 month period to 1% of amounts redeemed
during the sixth twelve month period after purchase.

Class C Shares - Level Load Option

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

         Shares of the Texas Fund and of KTFIF may be purchased in
exactly the same manner.  See "How to Buy Shares" in the
accompanying KTFIF Prospectus.

         With respect to Class B and Class C shares, no deferred sales charge is
imposed on amounts redeemed after the lapsing of the above described periods 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.


                                     - 14 -

<PAGE>




         Redemptions for both Funds may be made by submitting a redemption
request to KIRC or to the shareholder's broker-dealer. See "How to Redeem
Shares" in the accompanying KTFIF Prospectus.

         The Texas Fund Shares and KTFIF Shares have the same exchange rights.
Subject to certain limitations, such Shares may be exchanged for Shares of any
of the other funds in the Keystone America Fund Family on the basis of their
respective net asset values. See "Shareholder Services" in the accompanying
KTFIF Prospectus.

         In the proposed Reorganization, shareholders of the Texas Fund will
receive the corresponding class of Shares of KTFIF that they currently hold in
the Texas Fund. As indicated above, the Class A, B, and C Shares of KTFIF have
identical arrangements with respect to the imposition of initial and contingent
deferred sales charges as the comparable class of Shares of the Texas Fund.
Because the Reorganization will be effected at net asset value without the
imposition of an initial sales charge, Class A KTFIF Shares acquired by Class A
shareholders of the Texas Fund pursuant to the proposed Reorganization will not
be subject to any initial sales charge as a result of the Reorganization. KTFIF
Shares issued pursuant to the Reorganization that replace Texas Fund Shares
still subject to a contingent deferred sales charge will still be subject to
that charge.

Distribution Procedures and Payments

         The Texas Fund and KTFIF have adopted substantially similar 12b-1
Distribution Plans with regard to their respective Class A, B, and C Shares,
pursuant to which they incur certain distribution related expenses.

         Each Fund's Class A Distribution Plan provides for expenditures by the
Fund to pay costs related to sales of its Class A Shares, including shareholder
service fees. For KTFIF, expenses are currently limited to 0.25% annually of the
average daily net asset value of Class A Shares. For the Texas Fund, expenses
are currently limited to 0.15% annually of the average daily net asset value of
Class A Shares.

         Each Fund's Class B Distribution Plans provide for expenditures by the
Fund at an annual rate of up to 1.00% of the average daily net asset value of
Class B Shares to pay costs related to sales of its Class B Shares, including
shareholder service fees. For the Texas Fund, expenses incurred under its Class
B Distribution Plans are currently limited to 0.90% annually of the average
daily net asset value of Class B Shares.

         Each Fund's Class C Distribution Plan provides for expenditures by the
Fund at an annual rate of up to 1.00% of the average daily net asset value of 


                                     - 15 -

<PAGE>



Class C Shares to pay costs related to sales of its Class C Shares, including
shareholder service fees. For the Texas Fund, expenses incurred under its Class
C Distribution Plan are currently limited to 0.90% of the average daily net
asset value of Class C Shares.

         The NASD limits annual distribution expenditures to 1.00%, of which
0.75% may be used to pay distribution costs and 0.25% may be used to pay
shareholder service fees. The aggregate amount that each Fund may pay for such
distribution costs is limited to 6.25% of gross Share sales since the inception
of the Fund's Distribution Plan, plus interest at the prime rate plus 1.00% on
such amounts (less any contingent deferred sales charges paid by shareholders to
the Principal Underwriter) remaining unpaid from time to time.

         Payments under each Fund's Distribution Plans 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/or (2) as shareholder service fees
in respect of Shares maintained by the recipients on each of 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
discussed above.

         With respect to Class B Shares, the Principal Underwriter generally
reallows to brokers or others a commission in the amount of 4.00% of the price
paid for each Class B Share sold plus the first year's service fee in advance in
the amount of 0.25% of the price paid for each KTFIF Class B Share sold and
0.15% of the price paid for each Texas Fund Class B Share sold.

         With respect to Class C Shares, the Principal Underwriter generally
reallows to brokers or others a commission in the amount of 0.75% of the price
paid for each Class C Share sold plus the first year's service fee in advance in
the amount of 0.25% of the price paid for each Class C Share sold.

         After the Reorganization, it is anticipated that the commissions that
the Principal Underwriter will pay brokers or others for KTFIF Share sales and
shareholder service fees will remain the same as currently in effect for KTFIF
Shares.

         For more information, see "Distribution Plans" in the accompanying
KTFIF Prospectus.


Dividends and Distributions

         Each shareholder of the Texas Fund who becomes a shareholder of KTFIF
will be entitled to dividends and distributions of KTFIF.



                                     - 16 -

<PAGE>



         The Texas Fund declares dividends from net investment income daily and
distributes such dividends monthly and declares and distributes all net realized
long term capital gains annually.

         KTFIF declares dividends from net investment income monthly and
declares and distributes all net realized long term capital gains annually.

         For both Funds, distributions are payable in Shares of the relevant
Fund, 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.

         Unless a Texas Fund shareholder instructs or has instructed otherwise,
any distributions paid after the Effective Date will be automatically reinvested
in additional Shares of KTFIF without a sales charge. Texas Fund shareholders
will be deemed to have elected to receive dividends and distributions in the
same manner that he or she receives dividends and distributions on his or her
Texas Fund Shares. After the Reorganization, shareholders may elect, at any
time, to change the manner in which their dividends and distributions are paid.
See "Dividends and Taxes" in the accompanying KTFIF Prospectus.


Portfolio Manager

         Daniel A. Rabasco, the current portfolio manager of the Texas
Fund, is also responsible for the day to day portfolio management
of KTFIF.  Mr. Rabasco is a Keystone Vice President with more than
7 years of investment experience.


TAX CONSEQUENCES

Federal Income Taxes

         In the opinion of Sullivan & Worcester, legal counsel to the Texas
Fund, the Reorganization will constitute a tax free reorganization pursuant to
Section 368(a)(1)(C) of the Internal Revenue Code of 1986, as amended (the
"Internal Revenue Code"). No gain or loss will be recognized by the Texas Fund
or its shareholders as a result of the Reorganization. The tax basis and holding
period of the KTFIF Shares received by the Texas Fund shareholders will be the
same as the tax basis and holding period of the Texas Fund Shares surrendered
therefor. In addition, the tax basis and holding period of the assets of the
Texas Fund in the hands of KTFIF will be the same as the tax basis and holding
period of such assets in the hands of the Texas Fund prior to the
Reorganization. See "The Reorganization -- Federal Income Tax Consequences."

State Income Taxes

         Texas does not impose an income tax on individuals. Accordingly, unlike
shareholders in other state municipal bond mutual funds (such as mutual funds
investing primarily in California or New York municipal obligations), who are
generally able to exclude their mutual fund earnings from their state income
taxes, shareholders in the Texas Fund have enjoyed no such benefit.
Consequently, the exchange of shares in the Texas Fund for shares in KTFIF will
not have any impact on the taxes an individual shareholder pays to the State of
Texas.

         While Texas does not impose an income tax on corporations, it does
impose a corporate franchise tax on corporations that do business in Texas or
are chartered or authorized to do business in Texas. The corporate franchise tax
imposed on those corporations is based on the corporations "net taxable capital"
apportioned to Texas or the corporation's "net taxable earned surplus"
apportioned to Texas. Since neither earnings from the Texas Fund nor earnings
from KTFIF are considered gross receipts apportioned to Texas for purposes of
computing a corporation's "net taxable capital" apportioned to Texas, the
exchange of shares in the Texas Fund for shares in KTFIF will not have any
impact on the taxes a corporate shareholder pays to the State of Texas based on
"net taxable capital." The amount of "net taxable earned surplus" is based
generally on the corporation's "reportable federal taxable income" as computed
under the Internal Revenue Code. Since all "exempt interest dividends" excluded
from reportable federal taxable income by federal law are likewise excluded from
the net taxable earned surplus component upon which the Texas corporate
franchise tax may be imposed, the exchange of shares in the Texas Fund for
shares in KTFIF will not have any impact on the taxes a corporate shareholder
pays to the State of Texas based on "net taxable earned surplus."


                       PRINCIPAL RISK FACTORS


         Excepting the Texas Fund's emphasis on Texas debt securities and its
non-diversified status, the investment objectives, policies, and techniques of
the Texas Fund and KTFIF are substantially similar. Both Funds invest in the
same kinds of securities and use the same types of investment techniques.
Accordingly, the investment risks for both Funds are substantially similar.
Indeed, KTFIF's more broadly diversified portfolio may make it less susceptible
than the Texas Fund to adverse economic, political, or regulatory developments.

         The principal risk factor of investing in either the Texas Fund or
KTFIF is that the net asset value upon which the value of Shares is based will
increase or decrease in response to changes in


                                     - 18 -

<PAGE>



economic conditions, interest rates, and the market's perception of the Fund's
underlying portfolio securities.

         More specifically, the market value of the Funds' fixed income
securities investments may vary inversely to changes in prevailing interest
rates. In addition, the ability of each Fund to achieve its investment objective
is dependent upon the continuing ability of issuers of municipal bonds held in
the Fund's portfolio to meet their continuing obligation to pay interest and
principal when due. Furthermore, 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. Similar proposals
may be introduced in the future, which, if enacted, could materially affect the
availability of municipal bonds for investment by the Funds and the value of
each Fund's portfolio.

         Both Funds invest in securities with similar maturities, and both Funds
use substantially identical procedures for the valuation of portfolio
securities.

         Both Funds may enter into repurchase agreements and reverse repurchase
agreements, firm commitment agreements for securities and currencies, options
transactions, currency, and other financial futures contracts and related
options transactions for hedging purposes, and, in furtherance of their
investment objectives, certain other types of derivative instruments, including
structured securities. Both Funds may also invest in obligations denominated in
foreign currencies that are exempt from federal income tax. Each of these
investment techniques involve certain investment risks.

         There are risks associated with any investment program, and there can
be no assurance that KTFIF will achieve its investment objective.

         Each Fund's Prospectus contains a discussion of the Fund's investment
risks in the section entitled "Risk Factors." See also the "Additional
Investment Information" section at the back of the accompanying KTFIF
Prospectus.


                          THE REORGANIZATION


REASONS FOR THE PROPOSED TRANSACTION

          The Board of Trustees of the Texas Fund, including all of the Fund's
Independent Trustees, has determined that the tax-free Reorganization would be
in the best interests of the Fund, would not dilute the interests of the Fund's
shareholders, and would not impose an unfair burden on the Fund.


                                     - 19 -

<PAGE>


         The Board of Trustees has proposed the transaction in the interest of
providing a cost effective investment alternative for the Texas Fund
shareholders. As KTFIF shareholders, the Texas Fund shareholders can continue to
pursue the highest possible current income, exempt from federal income taxes,
while preserving capital. Continuity of investment management as well as all
other investor services (including exchange privileges with the other funds in
the Keystone America Fund Family) currently provided to the Texas Fund will be
maintained.

         The combination of the two Funds should permit the Texas Fund
shareholders, as shareholders of KTFIF, to pursue the same investment objective
in a larger fund with the following resulting advantages (although no assurance
can be given that these benefits will be obtained):

         1. Economies of scale - The proposed reorganization is expected to
reduce operating expenses for the Texas Fund. Investment management and
custodial fees are reduced as the asset base reaches certain levels, thus
decreasing as assets increase. Fixed expenses such as accounting, legal, and
printing costs will be spread over a larger asset base resulting in per share
expense reductions or economies of scale. For example, KTFIF's Class A, B, and C
pro forma annual operating expense ratios, after giving effect to the
Reorganization, are estimated to be 1.18%, 1.93, and 1.93%, respectively, of
each class's average net assets. In contrast, the Texas Fund's unsubsidized
Class A, B, and C annual operating expense ratios for its most recently
completed fiscal year were 2.57%, 3.36%, and 3.28%, respectively, of each
class's average net assets.

         As of December 31, 1995, the Texas Fund's net assets were approximately
$5.6 million, and KTFIF's net assets were approximately $147.0 million.

         2. Increased investment opportunities - It is expected that the
combined Fund will be more easily and efficiently managed. A larger single asset
base reduces transaction costs, might result in reduced portfolio turnover, and
provides the opportunity to obtain a wider variety of investments.

         3. Facilitate marketing and distribution efforts - It is expected that
the combined Fund will facilitate marketing and distribution efforts with a view
toward increasing the asset base, which in turn will benefit shareholders as
described in (1) and (2) above.

         The Board of Trustees of KSTFF based their decision to recommend the
Reorganization on a number of factors, including the following:



                                     - 20 -

<PAGE>



         1.       projected expense ratios and information regarding fees
                  and expenses of the Texas Fund and KTFIF;

         2.       the terms and conditions of the Reorganization and
                  whether it would result in dilution of the interests of
                  the Texas Fund shareholders;

         3.       the compatibility of the Texas Fund, its investment
                  objective, policies, and restrictions with those of
                  KTFIF;

         4.       the costs to the Texas Fund of the Reorganization;

         5.       the tax consequences to the Texas Fund and its
                  shareholders resulting from the Reorganization;

         6.       the availability to KTFIF shareholders of shareholder
                  services identical to those available to the Texas Fund
                  shareholders; and

         7.       the possible investment benefits to be gained from a
                  single larger fund.

         The above-cited benefits offset any loss to Texas Fund shareholders
that might arise from their ownership of Shares of KTFIF, which is not devoted
to investments in Texas municipal bonds, as opposed to their ownership of Shares
of the Texas Fund, which focuses primarily on such Texas bonds.

AGREEMENT ON THE TRANSFER OF ASSETS

         The terms and conditions under which the Reorganization are to be
consummated are set forth in the Reorganization Agreement. Significant
provisions of the Reorganization Agreement are summarized below. This summary,
however, is qualified in its entirety by reference to the Reorganization
Agreement, a copy of which is attached hereto as Exhibit A.

         The Reorganization Agreement provides that all of the assets of the
Texas Fund will be transferred to KTFIF in exchange for Shares of KTFIF and the
liabilities of the Texas Fund will be assumed by KTFIF on the Effective Date
(the later of (i) receipt of all necessary regulatory approvals, (ii) final
adjournment of the meeting of the shareholders of the Texas Fund at which the
Reorganization Agreement will be considered so long as the Reorganization
Agreement is approved by the shareholders, or (iii) such later date as the
parties to the Reorganization Agreement may mutually agree upon).

         The number of full and fractional Class A, B, and C KTFIF Shares to be
delivered to the Texas Fund shareholders will be determined on the basis of the
relative net asset values of the


                                     - 21 -

<PAGE>



Class A, B, and C Shares of KTFIF and the Texas Fund as of the close of business
on the New York Stock Exchange on the Effective Date. The net asset value of a
KTFIF Share will be determined in the manner set forth in KTFIF's Prospectus, a
copy of which accompanies this Prospectus/Proxy Statement, except that such
computation will be made to the nearest hundredth of a cent. The valuation
practices of KTFIF are described under "Pricing Shares" in KTFIF's Prospectus.
The assets and liabilities of the Texas Fund will be valued in the same manner
as that used with respect to the valuation of the assets and liabilities of
KTFIF. The valuation procedures of both Funds are substantially identical. The
value of the Shares of the Texas Fund will be computed to the nearest hundredth
of a cent.

         Under the Reorganization Agreement, (i) all of the assets and
liabilities of the Texas Fund will be exchanged for Class A, B, and C Shares of
KTFIF; (ii) KTFIF Class A, B, and C Shares will be distributed to the Class A,
B, and C shareholders of the Texas Fund, respectively, as of the close of
business on the Effective Date; and (iii) the Texas Fund will be liquidated. The
distribution of KTFIF Class A, B, and C Shares will be accomplished by the
establishment of open accounts on the records of KTFIF in the name of each Class
A, B, and C shareholder of the Texas Fund representing the respective pro rata
number of the appropriate Class of Shares of KTFIF due such shareholder.
Fractional Shares of KTFIF will be carried to the third decimal place. After the
Effective Date, KTFIF Share certificates will be issued only upon written
request, and such requests must be accompanied by any Share certificates issued
for Texas Fund Shares held by the investor.

         The Board of Trustees of KSTFF, including all of the Independent
Trustees, has determined that the interests of the existing shareholders of the
Texas Fund will not be diluted as a result of the Reorganization, and that the
Reorganization is in the best interests of the Texas Fund shareholders. The
Board of Trustees of KTFIF, including all of the Independent Trustees, has made
the same determinations with respect to the interests of the existing
shareholders of KTFIF.

         The consummation of the Reorganization is subject to a number of
conditions set forth in the Reorganization Agreement. Notwithstanding approval
by shareholders of the Texas Fund, the Reorganization Agreement may be
terminated at any time prior to the consummation of the Reorganization without
liability on the part of either party or its respective Trustees, officers or
shareholders, by either party on written notice to the other party if
circumstances should develop that, in the opinion of the Funds, make proceeding
with the Reorganization inadvisable. The Reorganization Agreement may be
amended, waived or supplemented in such manner as may be mutually agreed upon by
the authorized officers of the Funds; provided, however, that following the
Meeting, no such amendment, waiver or supplement may have the


                                     - 22 -

<PAGE>



effect of changing the provision for determining the number of KTFIF Shares to
be issued to Texas Fund shareholders to the detriment of such shareholders
without their approval.

         KTFIF will pay the expenses (consisting primarily of legal, accounting,
custodian, and transfer agents fees, as well as printing and mailing and other
expenses in connection with the registration of KTFIF Shares under the 1933 Act)
incurred by it in connection with the Reorganization. The Texas Fund will pay
the expenses of printing and mailing this Prospectus/Proxy Statement and other
material to the Texas Fund shareholders as well as the expenses of conducting
additional proxy solicitations.


DESCRIPTION OF THE SECURITIES TO BE ISSUED

         KTFIF is an open-end, diversified management investment company
organized as a Massachusetts business trust. KTFIF currently offers and issues
to the public Class A, B, and C Shares. After the Reorganization, KTFIF will
continue to offer and issue all three classes. Each class participates in
dividends and distributions. Each class has equal voting, liquidation, and other
rights, including rights of appraisal, except (i) expenses related to the
distribution of each class of Shares, or other expenses that the Board of
Trustees may designate as class expenses from time to time, are borne solely by
each class; (ii) each class of Shares has exclusive voting rights with respect
to its 12b-1 Plan; (iii) each class has different exchange privileges; and (iv)
each class generally has a different designation. Subject to certain
limitations, KTFIF Shares may be exchanged for the same class of Shares of other
members of the Keystone America Family and Keystone Liquid Trust, but will have
no other preference, conversion, exchange, or preemptive rights.

         KTFIF shareholders are entitled to one vote for each full Share owned
and fractional votes for fractional Shares. Shares of the Fund vote together
except when required by law to vote separately by series or class. The Fund is
not required to hold annual meetings. The Fund will hold special meetings from
time to time as required under its Declaration of Trust and the 1940 Act. A
special meeting of shareholders will be held when 10% of the outstanding shares
request a meeting for the purpose of removing a Trustee.

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

         The foregoing is only a summary of certain of the provisions of KTFIF's
Declaration of Trust and By-laws, Shareholders should refer to the provisions of
the Declaration of Trust Agreement and By-laws for their full terms.


FEDERAL INCOME TAX CONSEQUENCES

         The completion of the Reorganization is contingent upon the receipt by
the Texas Fund of an opinion from Sullivan & Worcester that, on the basis of the
existing provisions of the Internal Revenue Code, Treasury regulations, current
administrative rules, and court decisions, for federal income tax purposes: (i)
no gain or loss will be recognized by the Texas Fund or KTFIF as a result of the
Reorganization; (ii) the basis of the assets of the Texas Fund in the hands of
KTFIF will be the same as the basis of those assets in the hands of the Texas
Fund immediately prior to the Reorganization; (iii) the holding period of the
Texas Fund's assets in the hands of KTFIF will include the period during which
the assets were held by the Texas Fund; (iv) no gain or loss will be recognized
by shareholders of the Texas Fund as a result of the Reorganization; (v) the
basis of KTFIF Shares received by the Texas Fund shareholders will be the same
as the basis of the Texas Fund Shares surrendered therefor; and (vi) the holding
period of KTFIF Shares received by the Texas Fund shareholders will include the
holding period during which the Texas Fund Shares surrendered in exchange
therefor were held, provided that such Shares were held as a capital asset in
the hands of the Texas Fund shareholders on the date of the Reorganization.

         As of January 23, 1996, the Texas Fund had available, for federal
income tax purposes, unused capital loss carry forwards of $80,704 expiring in
2002. As a result of the Reorganization, the unused capital loss carryforwards
will become tax attributes of KTFIF, and the utilization of the carryforwards
will benefit all the shareholders of KTFIF. If the Reorganization is
consummated, KTFIF will be constrained, however, in the extent to which it can
use the capital loss carryforwards of the Texas Fund because of limitations
imposed by the Internal Revenue Code upon the occurrence of an "ownership
change." KTFIF should be able to use in each year from 1996 through 2002,
capital loss carryforwards in an amount equal to the value of the Texas Fund on
the date of the Reorganization multiplied by a long-term tax-exempt rate
calculated by the Internal Revenue Service (currently about 6%). If the amount
of such losses is not used in one year, it may be added to the amount available
for use in the next year.

         The Texas Fund shareholders should consult their tax advisers regarding
the tax effects, if any, of the proposed Reorganization in light of their
individual circumstances. Since the foregoing discussion relates only to the
federal income tax consequences of the Reorganization, shareholders of the Texas
Fund should also


                                     - 24 -

<PAGE>



consult their tax advisers as to the state and local tax
consequences, if any, of the Reorganization.

CAPITALIZATION

         The following table shows the capitalization of KTFIF and the Texas
Fund as of December 31, 1995 and on a pro forma basis as of that date after
giving effect to the proposed acquisition of assets of the Texas Fund at the
then net asset value per Share. The pro forma data reflects an exchange ratio of
1.07, 1.06, and 1.06 for the KTFIF Class A, B, and C Shares, respectively,
issued for each Class A, B, and C Share, respectively, of the Texas Fund:

         The table set forth above should not be relied on to reflect the number
of Shares to be received in the Reorganization; the actual number of Shares to
be received will depend upon the net asset value and number of Shares
outstanding of each Fund at the time of the Reorganization.

into as of _____________, by and between Keystone Tax Free Income Fund
("KTFIF"), a Massachusetts business trust, and Keystone State Tax Free Fund
("KSTFF"), a Massachusetts business trust (each, a "Fund," and together, the

         WHEREAS, KTFIF and KSTFF have agreed, subject to the receipt of the

Texas Fund to KTFIF in exchange for shares of KTFIF, with KTFIF assuming the
liabilities of the Texas Fund to the extent provided herein;

         WHEREAS, following the reorganization, shares of KTFIF will be

         WHEREAS, the reorganization described in this Agreement is intended to

         SECTION 1.                 EXCHANGE OF ASSETS FOR SHARES

         1.1 Terms of Exchange.

         (a) Upon the Effective Date (as defined in Subsection 1.2 below),
KSTFF, on behalf of the Texas Fund will sell, transfer, and deliver to KTFIF
good and marketable title to all of the then existing assets of the Texas Fund
free and clear of all liens, claims, charges, options, and encumbrances.

         (b) KTFIF will assume and pay, to the extent that they exist on the
Effective Date, all the liabilities of the Texas Fund, whether absolute,
accrued, contingent, or otherwise.

         (c) KTFIF will deliver to the Texas Fund that number of full and
fractional shares of KTFIF having an aggregate net asset value equal to the
aggregate net asset value of the Texas Fund, all determined as provided in
Section 1.1(d) below.

         (d) The following provisions shall apply to the determination of the
number of shares of KTFIF to be delivered:

                  (i) The net asset value per share of KTFIF shall be determined
as of the close of business on the New York Stock Exchange (the ""Exchange") on
the Effective Date.

                  (ii) The net value of the assets and liabilities of the Texas
Fund shall be determined as of the close of business on the Exchange on the
Effective Date.

                  (iii) The net asset value per share of the Texas Fund shall be
determined as of the close of business on the Exchange on the Effective Date.

                  (iv) The net asset value of KTFIF shall be computed in the
manner set forth in KTFIF's current Registration Statement under the Securities
Act of 1933 ("1933 Act") and the 1940 Act, except that such computation shall be
made to the nearest one-hundredth of a cent.

                  (v) The assets and liabilities of the Texas Fund shall be
valued in the same manner as that used with respect to the valuation of the
assets and liabilities of KTFIF in the computation of the net asset value per
share of KTFIF.

                  (vi) The net asset value per share of the Texas Fund shall be
computed by dividing the net value of the assets and liabilities of the Texas
Fund, determined as provided in (ii) and (v) above, by the number of shares of
the Texas Fund outstanding as of the close of business on the Exchange on the
Effective Date; and such computation shall be made to the nearest one-hundredth
of a cent.

<PAGE>




                  (vii) The net asset value per share of the Texas Fund
determined as provided in (vi) above shall be divided by the net asset value per
share of KTFIF determined as provided in (i) and (iv) above; and the result of
such division shall be calculated to six decimal places (the "Conversion
Ratio").

                  (viii) The number of shares of the Texas Fund outstanding at
the close of business on the Exchange on the Effective Date shall be multiplied
by the Conversion Ratio to determine the number of shares of KTFIF to be
delivered.

                  (ix) KPMG Peat Marwick LLP shall provide a written report to
each of KTFIF and KSTFF on procedures they will have performed to determine the
accuracy of the computations required by this Section 1.1(d).

                  1.2 Closing and Effective Date. The closing shall be held at

under this Agreement.

treasury of the Texas Fund immediately prior to the Effective Date shall be
cancelled upon the Effective Date without conversion into shares of KTFIF.

                  1.6 Transfer Taxes. Any transfer taxes payable upon issuance

                 MANAGEMENT'S DISCUSSION OF KTFIF'S PERFORMANCE
                   FOR THE FISCAL YEAR ENDED NOVEMBER 30, 1995


A Discussion With
Your Fund Manager

Betsy A. Blacher is the senior portfolio manager of your Fund and leads
Keystone's municipal bond investment team. Ms. Blacher is a professional with
16 years of investment experience specializing in municipal bonds. She holds
a Bachelor's degree from Wheaton College in economics and sociology.
Together, with portfolio managers Daniel Rabasco and George Kimball and
analyst David Moore, the team evaluates municipal bonds for Keystone tax free
funds.

Q What does the Fund offer investors?

A The Fund is designed for tax-sensitive investors. It seeks consistent,
attractive income that is exempt from federal income tax.(3) The Fund offers
professional management and diversification by investing in investment grade
municipal bonds. We manage the Fund with careful attention to credit quality
and financial stability.

Q How did municipal bonds perform over the past year?

A Municipal bonds rebounded strongly as a slowing economy reduced the threat
of higher interest rates and inflation. Most bond holders more than recovered
from their losses in 1994 and recorded double-digit total returns. This was a
reversal from 1994 when yields rose and bond prices declined. As growth
moderated at the start of 1995, municipal bonds rallied resulting in
unusually positive total returns.

Q How did the Fund perform?

A The Fund generated returns that paralleled the strong performance of the
municipal bond market. At the beginning of 1995 we expected economic growth
to moderate and interest rates to decline. So, we emphasized bonds that we
expected to benefit from declining rates: non-callable, discount and zero
coupon bonds. Since callable bonds are likely to be bought back by the issuer
in this type of environment, we emphasized noncallable bonds to preserve
income as rates declined. At the same time, these bonds became expensive
relative to other municipal bonds and this contributed to the Fund's price
appreciation.

   Discount bonds are sold at a discount from par, or value at maturity.
Historically these bonds have tended to provide more price appreciation in a
falling rate environment than bonds priced close to or above par.

   Zero coupon bonds represented a small portion of the portfolio. But, these
bonds were important contributors to the Fund's strong price recovery.
Because zeroes pay income at maturity, they have historically tended to be
the most sensitive to changes in interest rates. As rates declined, they were
among the best performing holdings in the portfolio.

   We were pleased with the results of this strategy which helped the Fund
participate in the strong recovery of municipal bonds this year.

Q Total returns were impressive, but municipal bond yields declined. Why?

A Yields declined for nearly every municipal bond investor, including
Keystone Tax Free Income Fund. Slower economic growth lessens the potential
for higher inflation which reduces net bond yields. We held a number of high
coupon bonds and attempted to lock-in income by emphasizing selected
non-callable bonds. While the Fund's income still declined, we believe the
portfolio's holdings of these bonds helped the portfolio to maintain income.

Keystone Tax Free Income Fund

In evaluating bonds for the Fund, Keystone looks for . . .

(bullet) Strong credit ratings; bonds rated in the top 4 categories (AAA, AA,
         A, BBB)
(bullet) Responsible fiscal policies
(bullet) Solid financial positions
(bullet) Attractive values

Keystone's municipal bond team also evaluates local economic conditions, the
state legislative climate, the taxing power of the issuer and expected cash
flows from the project.

Q Did talk about a 'flat tax' in Washington affect municipal bonds?

A Discussions about a 'flat tax' limited performance that otherwise would have
been stronger than the impressive returns of 1995. The 'flat tax' would have
been a negative for municipal bonds because it would have taxed municipal
bond income. At this writing, the possibility of such a tax appears remote.
But, the mere discussion of it caused municipal bonds to rise less in price
than comparable U.S. Treasuries. As a result, we believe that municipals are
still attractive values.

Q What is your outlook?

A We continue to be cautiously optimistic about the municipal bond market. We
expect the economy to continue slowing to a sustainable, non-inflationary
level. This should provide the potential for stable to declining interest
rates over the next six months. In particular, we expect short-term interest
rates to decline further, which could result in some price appreciation.

Q Why do you think growth will remain slow?

A Demographics are important to economic growth. With new home sales and new
family formation slowing, we think economic growth should remain moderate
compared to the 1980s and early 1990s. In addition, world economic growth is
a factor. In Europe, growth has been slow, even with cuts in interest rates.
Because U.S. growth is increasingly dependent on world growth, economic
growth should not be a threat to bond investors for some time. Combined with
a proposal to balance the federal budget, these could be strong positives for
municipal bond investors over the long term.

Q What should shareholders expect?

A We think shareholders should not expect a repeat of the unusually positive
performance of 1995; investors should look forward to returns to come
primarily from income rather than price appreciation in the months ahead.

Q Are municipal bond funds still a good value?

A Even after such a great year, we believe municipal bond yields are still
very attractive values compared to taxable bond yields. On November 30 the
yield on a 30-year AA-rated municipal bond equaled 93% of the yield on a
comparable U.S. Treasury bond. As rates declined, taxable bond yields
declined more than tax free yields. This increased the attractiveness of
municipal bonds compared to taxable bonds. As a result, the after-tax yield
of municipal bonds remains relatively high by historical standards.

Item 17.  Undertakings

         (1)      The undersigned Registrant agrees that prior to any
                  public reoffering of the securities registered through
                  the use of a prospectus that is part of this
                  Registration Statement by any person or party who is
                  deemed to be an underwriter within the meaning of Rule
                  145(c) of the Securities Act of 1933, the reoffering
                  prospectus will contain the information called for by
                  the applicable registration form for reofferings by
                  persons who may be deemed underwriters, in addition to
                  the information called for by the other items of the
                  applicable form.

         (2)      The undersigned Registrant agrees that every prospectus
                  that is filed under paragraph (1) above will be filed
                  as a part of an amendment to the Registration Statement
                  and will not be used until the amendment is effective,
                  and that, in determining any liability under the
                  Securities Act of 1933, each post-effective amendment

Keystone Tax Free Income Fund
200 Berkeley Street
Boston, MA  02116-5034


Gentlemen:

         I am a Senior Vice President of and General Counsel to Keystone
Investment Management Company (formerly named Keystone Custodian Funds, Inc.),
investment adviser to Keystone Tax Free Income Fund (the "Fund"), a
Massachusetts business trust. I have been asked to render an opinion with
respect to the issuance of certain shares of beneficial interest, without par
value, of the Fund (the "Shares") in connection with the proposed acquisition by
the Fund of substantially all of the assets of the Keystone Texas Tax Free Fund,
a portfolio of Keystone State Tax Free Fund (the "Reorganization"). The offering
of the Shares pursuant to the Reorganization is the subject of a certain
registration statement (the "Registration Statement") on Form N-14, which is
being filed by the Fund with the Securities and Exchange Commission under the
Securities Act of 1933, as amended.

         I have examined originals, or copies, certified or otherwise identified
to my satisfaction, of such certificates, records and other documents as I have
deemed necessary or appropriate for the purposes of this opinion.

         Based upon the foregoing, I am of the opinion that the Shares, when
issued and sold in accordance with the terms of the Registration Statement, will
be legally issued, fully paid and non-assessable by the Fund.

         I hereby consent to the filing of this opinion as an exhibit to the
Registration Statement.


                                               Sincerely yours,

                                               /s/ Rosemary D. Van Antwerp

                                                   Rosemary D. Van Antwerp
                                                   Senior Vice President and
                                                   General Counsel

         Re: Acquisition of Assets of Keystone Texas Tax Free Fund

Ladies and Gentlemen:

         You have asked for our opinion as to certain tax consequences of the
proposed acquisition of assets of Keystone Texas Tax Free Fund ("Selling Fund"),
a separate portfolio of Keystone State Tax Free Fund, a Massachusetts business
trust, by Keystone Tax Free Income Fund ("Acquiring Fund"), also a Massachusetts
business trust, in exchange for voting shares of Acquiring Fund (the
"Reorganization").

         In rendering our opinion, we have reviewed and relied upon the draft
Prospectus/Proxy Statement circulated January 21, 1996 and associated form of
Agreement and Plan of Reorganization (the "Reorganization Agreement") and
expected to be filed with the Securities and Exchange Commission on or about
February 2, 1996. We have relied, without independent verification, upon the
factual statements made therein, and assume that there will be no change in
material facts disclosed therein between the date of this letter and the date of
closing of the Reorganization. We further assume that the Reorganization will be
carried out in accordance with the Reorganization Agreement. We have also relied
upon the following representations, each of which has been made to us by
officers of Acquiring Fund or of Selling Fund:

         A. The Reorganization will be consummated substantially as described in
the Reorganization Agreement.

         B. Acquiring Fund will acquire from Selling Fund at least 90% of the
fair market value of the net assets and at least 70% of the fair market value of
the gross assets held by Selling Fund immediately prior to the Reorganization.
For purposes of this

<PAGE>

representation, assets of Selling Fund used to pay reorganization expenses, cash
retained to pay liabilities, and redemptions and distributions (except for
regular and normal distributions) made by Selling Fund immediately preceding the
transfer which are part of the plan of reorganization, will be considered as
assets held by Selling Fund immediately prior to the transfer.

         C. To the best knowledge of management of Selling Fund, there is
no plan or intention on the part of the shareholders of Selling Fund to sell,
exchange, or otherwise dispose of a number of Acquiring Fund shares received in
the Reorganization that would reduce the former Selling Fund shareholders'
ownership of Acquiring Fund shares to a number of shares having a value, as of
the date of the Reorganization (the "Closing Date"), of less than 50 percent of
the value of all of the formerly outstanding shares of Selling Fund as of the
same date. For purposes of this representation, Selling Fund shares exchanged
for cash or other property will be treated as outstanding Selling Fund shares on
the Closing Date. There are no dissenters' rights in the Reorganization, and no
cash will be exchanged for Selling Fund shares in lieu of fractional shares of
Acquiring Fund. Moreover, shares of Selling Fund and shares of Acquiring Fund
held by Selling Fund shareholders and otherwise sold, redeemed, or disposed of
prior or subsequent to the Reorganization will be considered in making this
representation, except for shares of Selling Fund or Acquiring Fund redeemed in
the ordinary course of business of Selling Fund or Acquiring Fund in accordance
with the requirements of section 22(e) of the Investment Company Act of 1940.

         D. Selling Fund has not redeemed and will not redeem the shares of any
of its shareholders in connection with the Reorganization except to the extent
necessary to comply with its legal obligation to redeem its shares.

         E. The management of Acquiring Fund has no plan or intention to redeem
or reacquire any of the Acquiring Fund shares to be received by Selling Fund
shareholders in connection with the Reorganization, except to the extent
necessary to comply with its legal obligation to redeem its shares.

         F. The management of Acquiring Fund has no plan or intention to sell or
dispose of any of the assets of Selling Fund which will be acquired by Acquiring
Fund in the Reorganization, except for dispositions made in the ordinary course
of business, and to the extent necessary to enable Acquiring Fund to comply with
its legal obligation to redeem its shares.

         G. Following the Reorganization, Acquiring Fund will continue the
historic business of Selling Fund in a substantially unchanged manner as part of
the regulated investment company business of Acquiring Fund, or will use a
significant portion of Selling Fund's historic business assets in a business.

         H. There is no intercorporate indebtedness between Acquiring Fund and
Selling Fund.

         I. Acquiring Fund does not own, directly or indirectly, and has not
owned in the last five years, directly or indirectly, any shares of Selling
Fund. Acquiring Fund will not acquire any shares of Selling Fund prior to the
Closing Date.

         J. Acquiring Fund will not make any payment of cash or of property
other than shares to Selling Fund or to any shareholder of Selling Fund in
connection with the Reorganization.

         K. Pursuant to the Reorganization Agreement, the shareholders of
Selling Fund will receive solely Acquiring Fund voting shares in exchange for
their voting shares of Selling Fund.

         L. The fair market value of the Acquiring Fund shares to be received by
the Selling Fund shareholders will be approximately equal to the fair market
value of the Selling Fund shares surrendered in exchange therefor.

         M. Subsequent to the transfer of Selling Fund's assets to Acquiring
Fund pursuant to the Reorganization Agreement, Selling Fund will distribute the
shares of Acquiring Fund, together with other assets it may have, in final
liquidation as expeditiously as possible.

         N. Selling Fund is not under the jurisdiction of a court in a Title 11
or similar case within the meaning of ss. 368(a)(3)(A) of the Internal Revenue
Code of 1986, as amended (the "Code").

         O. Selling Fund is treated as a corporation for federal income tax
purposes and at all times in its existence has qualified as a regulated
investment company, as defined in ss. 851 of the Code.

         P. Acquiring Fund is treated as a corporation for federal income tax
purposes and at all times in its existence has qualified as a regulated
investment company, as defined in ss. 851 of the Code.

         Q. The sum of the liabilities of Selling Fund to be assumed by
Acquiring Fund and the expenses of the Reorganization does not exceed twenty
percent of the fair market value of the assets of Selling Fund.

         R. The foregoing representations are true on the date of this letter
and will be true on the date of closing of the Reorganization.

         Based on and subject to the foregoing, and our examination of the legal
authority we have deemed to be relevant, it is our opinion that for federal
income tax purposes:

         1. The acquisition by Acquiring Fund of substantially all of the assets
of Selling Fund solely in exchange for voting shares of Acquiring Fund followed
by the distribution by Selling Fund of said Acquiring Fund shares to the
shareholders of Selling Fund in exchange for their Selling Fund shares will
constitute a reorganization within the meaning of ss. 368(a)(1)(C) of the Code,
and Acquiring Fund and Selling Fund will each be "a party to a reorganization"
within the meaning of ss. 368(b) of the Code.

         2. No gain or loss will be recognized to Selling Fund upon the transfer
of substantially all of its assets to Acquiring Fund solely in exchange for
Acquiring Fund voting shares and assumption by Acquiring Fund of certain
identified liabilities of Selling Fund, or upon the distribution of such
Acquiring Fund voting shares to the shareholders of Selling Fund in exchange for
all of their Selling Fund shares.

         3. No gain or loss will be recognized by Acquiring Fund upon the
receipt of the assets of Selling Fund (including any cash retained initially by
Selling Fund to pay liabilities but later transferred) solely in exchange for
Acquiring Fund voting shares and assumption by Acquiring Fund of certain
identified liabilities of Selling Fund.

         4. The basis of the assets of Selling Fund acquired by Acquiring Fund
will be the same as the basis of those assets in the hands of Selling Fund
immediately prior to the transfer, and the holding period of the assets of
Selling Fund in the hands of Acquiring Fund will include the period during which
those assets were held by Selling Fund.

         5. The shareholders of Selling Fund will recognize no gain or loss upon
the exchange of all of their Selling Fund shares solely for Acquiring Fund
voting shares. Gain, if any, will be realized by Selling Fund shareholders who
in exchange for their Selling Fund shares receive other property or money in
addition to Acquiring Fund shares, and will be recognized, but not in excess of
the amount of cash and the value of such other property received. If the
exchange has the effect of the distribution of a dividend, then the amount of
gain recognized that is not in excess of the ratable share of undistributed
earnings and profits of Selling Fund will be treated as a dividend.

         6. The basis of the Acquiring Fund voting shares to be received by the
Selling Fund shareholders will be the same as the basis of the Selling Fund
shares surrendered in exchange therefor.

         7. The holding period of the Acquiring Fund voting shares to be
received by the Selling Fund shareholders will include the period during which
the Selling Fund shares surrendered in exchange therefor were held, provided the
Selling Fund shares were held as a capital asset on the date of the exchange.

         This opinion letter is delivered to you in satisfaction of the
requirements of Paragraphs 6.9 and 7.9 of the Reorganization Agreement. We
hereby consent to the filing of this opinion as an exhibit to the Registration
Statement on Form N-14 and to use of our name and any reference to our firm in
the Registration Statement or in the Prospectus/Proxy Statement constituting a
part thereof. In giving such consent, we do not thereby admit that we come
within the category of persons whose consent is required under Section 7 of the
Securities Act of 1933, as amended, or the rules and regulations of the
Securities and Exchange Commission thereunder.

1  Class B shares purchased on or after June 1, 1995 convert tax free to Class A
   shares after eight years. See "Class B Shares" for more information.

2  Class C shares are available only through dealers who have entered into
   special distribution agreements with Keystone Investment Distributors
   Company, the Fund's principal underwriter.

3  The sales charge applied to purchases of Class A shares declines as the
   amount invested increases. See "Class A Shares."

4  Purchases of Class A shares in the amount of $1,000,000 or more and/or
   purchases made by certain qualifying retirement or other plans are not
   subject to a sales charge, but may be subject to a contingent deferred sales
   charge. See the "Class A Shares" and "Contingent Deferred Sales Charge and
   Waiver of Sales Charges" sections of this prospectus for an explanation of
   the charge.

5  There is no exchange fee for exchange orders received by the Fund directly
   from an individual shareholder over the Keystone Automated Response Line
   ("KARL"). (For a description of KARL, see "Shareholder Services.")

6  Expense ratios shown above are for the Fund's fiscal year ended November 30,
   1994.

7  Long term shareholders may pay more than the economic equivalent of the
   maximum front end sales charges permitted by rules adopted by the National
   Association of Securities Dealers, Inc. ("NASD").

8  The Securities and Exchange Commission requires use of a 5% annual return
   figure for purposes of this example. Actual return for the Fund may be
   greater or less than 5%.

THE FUND

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

INVESTMENT OBJECTIVE AND POLICIES

  The Fund seeks the highest possible current income, exempt from federal income
taxes, while preserving capital.

PRINCIPAL INVESTMENT
  The Fund invests substantially all and, under ordinary circumstances, at least
80% of its assets in federally tax-exempt obligations, including municipal bonds
and  notes  and  tax-exempt   commercial  paper  (municipal  bonds),   that  are
obligations issued by or on behalf of states, territories and possessions of the
United  States   ("U.S."),   the  District  of  Columbia  and  their   political
subdivisions, agencies and instrumentalities, the interest from which is, in the
opinion of counsel to the issuers of such  bonds,  exempt  from  federal  income
taxes.  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 that have been or may be issued by
or on behalf of public  authorities to finance  privately  operated  facilities.
General obligation bonds involve the credit of an issuer possessing taxing power
and are payable from the issuer's general unrestricted  revenues.  Their payment
may be dependent upon an appropriation by the issuer's  legislative body and may
be subject to  quantitative  limitations on the issuer's  taxing power.  Limited
obligation  or revenue  bonds are payable only from the revenues of a particular
facility  or class of  facilities  or, in some  cases,  from the  proceeds  of a
specific  revenue  source,  such as the  user of the  facility.  Since  the Fund
considers preservation of capital as well as the level of tax exempt income, the
Fund may realize less income than a fund willing to expose shareholders' capital
to greater risk.

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

  The Fund invests in municipal  bonds only if, at the date of investment,  they
are rated  within  the four  highest  grades by  Standard  & Poor's  Corporation
("S&P") (AAA, AA, A and BBB), by Moody's  Investors  Service,  Inc.  ("Moody's")
(AAA,  AA, A and BAA) by Fitch  Investor  Services,  Inc. -- Municipal  Division
("Fitch")  (AAA,  AA, A and BBB) or,  if not  rated or rated  under a  different
system,  are of  comparable  quality to  obligations  so rated as  determined by
Keystone.  Securities that are in the lowest  investment  grade (BBB or BAA) may
have some speculative characteristics.

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

OTHER ELIGIBLE SECURITIES
  The Fund may invest up to 20% of its assets under ordinary  circumstances  and
up to 100% of its assets for temporary defensive purposes in the following types
of instruments: (1) commercial paper, including master demand notes, that at the
date of investment is rated A-1, the highest  grade given by S&P,  PRIME-1,  the
highest grade given by Moody's or, if not rated by such services, is issued by a
company  that at the date of  investment  has an  outstanding  issue  rated A or
better by S&P or Moody's; (2) obligations, including certificates of deposit and
bankers' acceptances,  of banks or savings and loan associations having at least
$1 billion in assets as of the date of their most recently  published  financial
statements  that are  members  of the  Federal  Deposit  Insurance  Corporation,
including U.S. branches of foreign banks and foreign branches of U.S. banks; (3)
corporate  obligations  (maturing  in 13  months  or  less)  that at the date of
investment are rated A or better by S&P or Moody's;  (4)  obligations  issued or
guaranteed  by the U.S.  government or by any agency or  instrumentality  of the
U.S.; and (5) qualified  "private  activity"  industrial  development bonds, the
income from which, while exempt from federal income tax under Section 103 of the
Code, is includable in the calculation of the federal alternative minimum tax.

  The Fund may enter into repurchase and reverse repurchase agreements, purchase
and sell securities and currencies on a when issued and delayed  delivery basis,
write covered call and put options and purchase call and put options,  including
purchasing put or call options to close out existing  positions,  and may employ
new investment techniques with respect to such options. The Fund may also engage
in  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 and may use  subsequently
developed  investment  techniques  that  are  related  to any of its  investment
policies.

  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.

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

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

FUNDAMENTAL NATURE OF INVESTMENT OBJECTIVE
  The investment objective of the Fund and the requirement that the Fund invest,
under ordinary circumstances, at least 80% of its assets in federally tax-exempt
obligations  are  fundamental  and neither may be changed  without the vote of a
majority of the Fund's  outstanding shares (as defined in the Investment Company
Act of 1940  ("1940  Act"))  (which  means the  lesser of (1) 67% of the  shares
represented at a meeting at which more than 50% of the Fund's outstanding shares
are represented or (2) more than 50% of the outstanding shares).

INVESTMENT RESTRICTIONS

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

  Generally, the Fund may not do the following:

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

    (2) borrow money or enter into reverse  repurchase  agreements,  except that
  the Fund may enter into  reverse  repurchase  agreements  or borrow money from
  banks for temporary or emergency purposes in aggregate amounts up to one-third
  of the value of the Fund's net assets;  provided  that while  borrowings  from
  banks (not including reverse  repurchase  agreements)  exceed 5% of the Fund's
  net assets,  any such borrowings will be repaid before additional  investments
  are made;

    (3) purchase any security  (other than U.S.  government  securities)  of any
  issuer if as a result more than 25% of its total assets would be invested in a
  single industry 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; and

    (4)  invest  more  than  10% of its  assets  in  securities  with  legal  or
  contractual   restrictions  on  resale  or  in  securities  for  which  market
  quotations are not readily available,  or in repurchase agreements maturing in
  more than seven
   days.

  As a matter of practice,  the Fund treats  reverse  repurchase  agreements  as
borrowings  for purposes of  compliance  with the  limitations  of the 1940 Act.
Reverse  repurchase  agreements will be taken into account along with borrowings
from  banks for  purposes  of the 5% limit set  forth in the  second  investment
restriction above.

  The  foregoing  is only a summary of the Fund's  investment  restrictions  and
policies.  See the statement of additional  information for details and the full
text of the Fund's investment restrictions and related policies.

RISK FACTORS
GENERAL

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

  By itself,  the Fund does not constitute a balanced  investment 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
federally 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.

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  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.

OTHER CONSIDERATIONS
  The market value of fixed income  securities  in which the Fund may invest may
vary inversely to changes in prevailing interest rates.

  The Fund has undertaken to a state securities  authority to disclose that zero
coupon securities pay no interest to holders prior to maturity, and the interest
on these  securities  is reported as income to the Fund and  distributed  to its
shareholders.  These  distributions must be made from the Fund's cash assets or,
if necessary, from the proceeds of sales of portfolio securities.  The Fund will
not be able to purchase additional income producing securities with cash used to
make such  distributions  and its current income  ultimately may be reduced as a
result.  If and when the Fund  invests in zero coupon  bonds,  the Fund does not
expect to have enough zero coupon bonds to have a material effect on dividends.

PRICING SHARES

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

  The Fund  values  municipal  bonds on the basis of  valuations  provided  by a
pricing  service,   approved  by  the  Fund's  Board  of  Trustees,  which  uses
information with respect to transactions in bonds, quotations from bond dealers,
market transactions in comparable  securities and various  relationships between
securities in determining  value.  The Fund values  short-term  investments with
maturities  of sixty days or less when  purchased  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 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  according  to
procedures established by the Board of Trustees.

DIVIDENDS AND TAXES

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

  Because Class A shares bear most of the costs of  distribution  of such shares
through  payment of a front end sales  charge  while  Class B and Class C shares
bear  such  expenses  through  a  higher  annual   distribution   fee,  expenses
attributable to Class B shares and Class C shares will generally be higher.

  The Fund has  qualified  and  intends to qualify in the future as a  regulated
investment company under the Code. The Fund qualifies if, among other things, it
distributes to its  shareholders  at least 90% of its net investment  income for
its  fiscal  year.  The Fund  also  intends  to make  timely  distributions,  if
necessary, sufficient in amount to avoid the nondeductible 4% excise tax imposed
on a regulated  investment company when it fails to distribute,  with respect to
each calendar  year, at least 98% of its ordinary  income for such calendar year
and 98% of its net capital gains for the one-year period ending on October 31 of
such  calendar  year.  Any such  distribution  would be (1) declared in October,
November or December to shareholders of record in such a month,  (2) paid by the
following  January  31,  and  (3)  includable  in  the  taxable  income  of  the
shareholder for the year in which such distributions were declared.  If the Fund
qualifies and if it distributes  substantially  all of its net investment income
and net  capital  gains,  if any,  to  shareholders,  it will be relieved of any
federal income tax liability.

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

  The Fund  expects  that  substantially  all of its  dividends  will be "exempt
interest dividends," which will be treated by the shareholder as excludable from
federal gross income. In order to pay exempt interest dividends, at the close of
each  quarter,  at least 50% of the value of the Fund's  assets must  consist of
federally tax-exempt obligations. An exempt interest dividend is any dividend or
part thereof  (other than a capital gain dividend) paid by the Fund with respect
to its net federally  excludable  municipal  bond interest and  designated as an
exempt  interest  dividend in a written  notice mailed to each  shareholder  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 you receive an exempt interest  dividend
with  respect to any share and such  share is held for six  months or less,  any
loss on the sale or exchange of such share will be  disallowed  to the extent of
the exempt interest dividend amount.

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

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

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

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

  The  Fund  intends  to  distribute  its net  capital  gains  as  capital  gain
dividends;  such  dividends  are treated by  shareholders  as long-term  capital
gains.  Such  distributions  will be designated  as capital gain  dividends by a
written notice mailed to each  shareholder no later than 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 long-term
capital gains received by the shareholder.

  The Fund may acquire an option to "put" specified securities to municipal bond
dealers or issuers from whom the securities  are purchased.  It is expected that
the Fund will be treated  for  federal  income tax  purposes as the owner of the
municipal bonds acquired subject to the put. The interest on the municipal bonds
will be tax  exempt to the  Fund,  and the  purchase  prices  must be  allocated
between  such  securities  and the put based upon their  respective  fair market
values. The IRS has not issued a published ruling on this matter and could reach
a different conclusion.

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

  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 situation.

FUND MANAGEMENT AND EXPENSES

BOARD OF TRUSTEES

  Under  Massachusetts  law,  the Fund's  Board of  Trustees  has  absolute  and
exclusive control over the management and disposition of all assets of the Fund.
Subject  to  the  general  supervision  of  the  Board  of  Trustees,   Keystone
Management,  located at 200 Berkeley Street, Boston,  Massachusetts  02116-5034,
serves as  investment  manager to the Fund and is  responsible  for the  overall
management of the Fund's business and affairs.

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

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

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

0.25% of amounts over                                       $500,000,000

computed  as of the close of  business  each  business  day and paid or  accrued
daily.  During the fiscal year ended November 30, 1994, the Fund paid or accrued
to Keystone Management investment management and administrative services fees of
$1,005,305,  which  represented  0.61% of the Fund's average net assets. Of such
amount  paid to  Keystone  Management,  $854,509  was paid to  Keystone  for its
services to the Fund.

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

  Keystone  Investments  is a  corporation  predominantly  owned by current  and
former  members of  management  of Keystone  and its  affiliates.  The shares of
Keystone Investments common stock beneficially owned by management are held in a
number of voting trusts, the trustees of which are George S. Bissell,  Albert H.

provides  accounting,   bookkeeping,  legal,  personnel  and  general  corporate
services to Keystone  Management,  Keystone,  their  affiliates and the Keystone

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

  The Management  Agreement and the Advisory  Agreement  continue in effect from
year to year only so long as such continuance is specifically  approved at least
annually by the Board of  Trustees  or by vote of a majority of the  outstanding
shares of the Fund. In either case,  the terms of the  Management  Agreement and
the Advisory Agreement and continuance thereof must be approved by the vote of a
majority of the Fund's  Independent  Trustees in person at a meeting  called for
the  purpose  of  voting  on  such  approval.  The  Advisory  Agreement  may  be
terminated, without penalty, on 60 days' written notice by the Board of Trustees
of the Fund, Keystone  Management or Keystone,  or by a vote of the shareholders
of the Fund. The Management  Agreement and the Advisory Agreement will terminate
automatically upon assignment.

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

FUND EXPENSES
  The Fund will pay all of its expenses.  In addition to the investment advisory
and management  fees discussed  above,  the principal  expenses that the Fund is
expected  to pay  include  expenses  relating  to certain of its  Trustees,  its
transfer,  dividend  disbursing and shareholder  servicing agent, its custodian,
its  independent  auditors  and legal  counsel  to its Board of  Trustees;  fees
payable to government agencies, including registration and qualification fees of
the Fund and its shares under  federal and state  securities  laws;  and certain
extraordinary  expenses.  In  addition,  each class will pay all of the expenses
attributable  to it. Such expenses are currently  limited to  Distribution  Plan
expenses.  The Fund also pays its brokerage  commissions,  interest  charges and
taxes.

  For the fiscal year ended  November 30,  1994,  the Fund's Class A shares paid
1.13% of average net assets in expenses.  For the fiscal year ended November 30,
1994, the Fund's Class B and Class C shares paid 1.88% and 1.89%,  respectively,
of average net assets in expenses.

  During the fiscal year ended  November 30,  1994,  the Fund paid or accrued to
Keystone  Investor  Resource  Center,  Inc.  ("KIRC"),  the Fund's  transfer and
dividend disbursing agent, and Keystone Investments $18,676 as reimbursement for
certain  accounting  and printing  services and paid or accrued to KIRC $232,940

PORTFOLIO MANAGER
  Betsy A. Blacher has been the Fund's  portfolio  manager since 1990.  She is a
Keystone  Senior  Vice  President  and Group  Head and has more than 15 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 follow a policy of  considering as a factor the number of shares of
the Fund sold by the broker-dealer.  In addition,  broker-dealers may, from time
to time, be affiliated with the Fund, Keystone, the Fund's principal underwriter
or their affiliates.

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

PORTFOLIO TURNOVER
  The Fund's  portfolio  turnover  rates for the fiscal years ended November 30,
1994  and 1993  were 98% and 47%,  respectively.  High  portfolio  turnover  may
involve  correspondingly  greater  brokerage  commissions and other  transaction
costs,  which would be borne  directly by the Fund, as well as additional  gains
and/or losses to shareholders.  For additional  information  about brokerage and
distributions, see the statement of additional information.

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

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

  Orders for the purchase of Fund shares will be confirmed at the offering price
equal to the net asset  value per share  next  determined  after  receipt of the
order in proper form by the Principal Underwriter  (generally as of the close of
the Exchange on that day) plus,  in the case of Class A shares,  the  applicable
sales  charge.  Orders  received by dealers or other firms prior to the close of
the Exchange and received by the Principal Underwriter prior to the close of its
business day will be confirmed at the offering  price  effective as of the close
of the  Exchange on that day. The Fund  reserves the right to determine  the net
asset value more  frequently  than once a day if deemed  desirable.  Dealers and
other financial services firms are obligated to transmit orders promptly.

  Orders  for  shares  received  other than as stated  above  will  receive  the
offering price equal to the net asset value per share next determined (generally
the next business day's offering price) plus, in the case of Class A shares, the
applicable sales charge.

  The initial  purchase must be at least $1,000 for Class A, Class B and Class C
shares. There is no minimum amount for subsequent purchases.

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

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

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

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

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

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

  Each class of shares,  pursuant to its respective  Distribution  Plan, pays an
annual service fee of 0.25% of the Fund's average daily net assets  attributable
to  that  class.  In  addition  to the  0.25%  service  fee,  the  Class B and C
Distribution  Plans provide for the payment of an annual  distribution fee of up
to 0.75% of the  average  daily  net  assets  attributable  to their  respective
classes.

  Investors who would rather pay the entire cost of  distribution at the time of
investment,  rather  than  spread the cost over  time,  might  consider  Class A
shares.  Other investors might consider Class B or Class C shares,  depending on
the amount of the purchase and the intended length of investment; in which case,
100% of the purchase price is invested  immediately.  The Fund will not normally
accept any purchase of Class B shares in the amount of $250,000 or more and will
not normally  accept any purchase of Class C shares in the amount of  $1,000,000
or more.

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

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

  With respect to NAV  Purchases,  the  Principal  Underwriter  will pay broker/
dealers or others concessions based on (1) the investor's  cumulative  purchases
during the one-year  period  beginning with the date of the initial NAV Purchase
and (2) the investor's  cumulative  purchases  during each  subsequent  one-year
period  beginning  with the first NAV  Purchase  following  the end of the prior
period.  For such  purchases,  concessions  will be paid at the following  rate:
1.00% of the investment  amount up to  $2,999,999;  plus 0.50% of the investment
amount between  $3,000,000 and $4,999,999;  plus 0.25% of the investment  amount
over $4,999,999.

  Class A shares  acquired  on or after April 10,  1995 in an NAV  Purchase  are
subject to a contingent  deferred sales charge of 1.00% upon  redemption  during
the 24 month period commencing on the date the shares were originally purchased.
Certain Class A shares purchased without a front-end sales charge prior to April
10,  1995 are  subject  to a  contingent  deferred  sales  charge of 0.25%  upon
redemption  during the one year period  commencing  on the date such shares were
originally purchased.

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

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

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

  Since January 1, 1995 through June 30, 1995 and upon prior notification to the
Principal  Underwriter,  Class A shares may be  purchased  at net asset value by
clients of registered  representatives within six months after the redemption of
shares of any registered  open-end investment company not distributed or managed
by Keystone or its affiliates,  where the amount invested represents  redemption
proceeds from such unrelated  registered open-end  investment  company,  and the
shareholder  either (1) paid a front end sales  charge,  or (2) was at some time
subject to, but did not actually  pay, a contingent  deferred  sales charge with
respect to the redemption proceeds.

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

CLASS A DISTRIBUTION PLAN
  The Fund has adopted a  Distribution  Plan with  respect to its Class A shares
(the "Class A  Distribution  Plan") that  provides for  expenditures,  currently
limited  to 0.25%  annually  of the  average  daily net  asset  value of Class A
shares,  to pay expenses  associated  with the  distribution  of Class A shares.
Amounts  paid  by the  Fund  to the  Principal  Underwriter  under  the  Class A
Distribution  Plan are currently  used to pay others,  such as dealers,  service
fees at an annual  rate of up to 0.25% of the  average  daily net asset value of
Class A shares  maintained by such  recipients  outstanding  on the books of the
Fund for specified periods.

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

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

                                                 DEFERRED
                                                   SALES

REDEMPTION TIMING                                 IMPOSED
- -----------------                                 -------

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

No deferred sales charge is imposed on amounts redeemed thereafter.

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

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

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

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

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

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

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

CLASS C DISTRIBUTION PLAN
  The Fund has adopted a  Distribution  Plan with  respect to its Class C shares
("Class C Distribution  Plan") that provides for  expenditures at an annual rate
of up to 1.00% of the  average  daily net  asset  value of Class C shares to pay
expenses  of the  distribution  of Class C  shares.  Payments  under the Class C
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. Amounts paid or accrued to the
Principal  Underwriter  under (1) and (2) in the  aggregate  may not  exceed the
annual limitation referred to above.

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

CONTINGENT DEFERRED SALES CHARGE
AND WAIVER OF SALES CHARGES
  Any  contingent  deferred sales charge imposed upon the redemption of Class A,
Class B or Class C shares  is a  percentage  of the  lesser of (1) the net asset
value of the shares  redeemed or (2) the net asset value at the time of purchase
of such shares.  No contingent  deferred sales charge is imposed when you redeem
amounts  derived from (1)  increases in the value of your account  above the net
cost of such  shares due to  increases  in the net asset  value per share of the
Fund; (2) certain shares with respect to which the Fund did not pay a commission
on issuance,  including shares acquired through  reinvestment of dividend income
and capital gains  distributions;  (3) certain Class A shares held for more than
one or two years,  as the case may be,  from the date of  purchase;  (4) Class B
shares  held more than four  consecutive  calendar  years or more than 72 months
after the month of purchase,  as the case may be; or (5) Class C shares held for
more than one year  from the date of  purchase.  Upon  request  for  redemption,
shares not  subject to the  contingent  deferred  sales  charge will be redeemed
first. Thereafter, shares held the longest will be the first to be redeemed.

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

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

  In addition, no contingent deferred sales charge is imposed on a redemption of
shares of the Fund in the event of (1) death or disability  of the  shareholder;
(2) a lump-sum  distribution  from a 401(k) plan or other benefit plan qualified
under  the  Employee  Retirement  Income  Security  Act of 1974  ("ERISA");  (3)
automatic  withdrawals  from ERISA plans if the  shareholder  is at least 59 1/2
years old; (4) involuntary redemptions of accounts having an aggregate net asset
value  of less  than  $1,000;  (5)  automatic  withdrawals  under  an  automatic
withdrawal  plan of up to 1.5% per month of the  shareholder's  initial  account
balance;  (6)  withdrawals  consisting  of loan  proceeds to a  retirement  plan
participant;  (7)  financial  hardship  withdrawals  made by a  retirement  plan
participant; or (8) withdrawals consisting of returns of excess contributions or
excess deferral amounts made to a retirement plan participant.

ARRANGEMENTS WITH BROKER-DEALERS AND OTHERS
  From  time  to  time,  the  Principal   Underwriter  may  provide  promotional
incentives,  including  reallowance of up to the entire sales charge, to certain
dealers  whose  representatives  have sold or are  expected to sell  significant
amounts  of the Fund.  In  addition,  dealers  may,  from time to time,  receive
additional  cash  payments.   The  Principal  Underwriter  may  provide  written
information to dealers with whom it has dealer  agreements that relates to sales
incentive campaigns conducted by such dealers for their  representatives as well
as financial  assistance in connection with pre-approved  seminars,  conferences
and advertising.  No such programs or additional compensation will be offered to
the extent they are  prohibited by the laws of any state or any  self-regulatory
agency,  such as the NASD. Dealers to whom substantially the entire sales charge
on Class A shares is reallowed may be deemed to be  underwriters as that term is
defined under the Securities Act of 1933.

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

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

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

DISTRIBUTION PLANS

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

  The NASD limits the amount that a fund may pay annually in distribution  costs
for sale of its shares and  shareholder  service  fees.  NASD rules limit annual
expenditures  to 1% of the  aggregate  average daily net asset value of a fund's
shares, of which 0.75% may be used to pay such distribution  costs and 0.25% may
be used to pay shareholder service fees. The NASD rules also limit the aggregate
amount that the Fund may pay for such distribution costs to 6.25% of gross share
sales since the inception of the 12b-1  Distribution  Plan, plus interest at the
prime rate plus 1% on such amounts (less any  contingent  deferred sales charges
paid by shareholders to the Principal Underwriter) remaining unpaid from time to
time.

  The Principal Underwriter intends, but is not obligated, to continue to pay or
accrue distribution charges incurred in connection with the Class B Distribution
Plan that  exceed  current  annual  payments  permitted  to be  received  by the
Principal  Underwriter from the Fund. The Principal  Underwriter intends to seek
full  payment of such  charges  from the Fund  (together  with  annual  interest
thereon at the prime rate plus one  percent)  at such time in the future as, and
to the extent that,  payment  thereof by the Fund would be within the  permitted
limits. If the Fund's Independent  Trustees authorize such payments,  the effect
would be to extend the period of time  during  which the Fund incurs the maximum
amount of costs allowed by 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.

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

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

  Unreimbursed  distribution  expenses  under the Class B  Distribution  Plan at
November 30, 1994 were  $1,996,948  (6.92% of Class B net assets).  Unreimbursed
distribution  expenses under the Class C Distribution  Plan at November 30, 1994
were $2,087,302 (8.99% of Class C net assets).

  For the year ended November 30, 1994, the Fund paid the Principal  Underwriter
$269,046,  $241,979  and  $279,001  pursuant to its Class A, Class B and Class C
Distribution Plans, respectively.

  Dealers or others may receive  different  levels of compensation  depending on
which class of shares they sell.  Payments  pursuant to a Distribution  Plan are
included in the operating expenses of the class.

HOW TO REDEEM SHARES

  Fund shares may be redeemed  for cash at their  redemption  value upon written
order sent by you to the Fund,  c/o  Keystone  Investor  Resource  Center,  Inc.
("KIRC"),  and presentation to the Fund of a properly endorsed share certificate
if  certificates  have been issued.  Your  signature(s) on the written order and
certificates  must be guaranteed as described below. The redemption value is the
net asset value per share  adjusted  for  fractions of a cent and may be more or
less than your cost depending upon changes in the value of the Fund's  portfolio
securities between purchase and redemption.  In order to redeem by telephone you
must have completed the authorization in your account application.

REDEMPTION OF SHARES IN GENERAL
  At various times,  the Fund may be requested to redeem shares for which it has
not yet received good payment. In such a case, the Fund will mail the redemption
proceeds upon clearance of the purchase  check,  which may take up to 15 days or
more. Any delay may be avoided by purchasing shares with a certified check or by
bank wire of funds or EFT.  Although the mailing of a redemption check or wiring
or EFT of  redemption  proceeds  may be delayed,  the  redemption  value will be
determined and the redemption  processed in the ordinary course of business upon
receipt of proper documentation.  In such a case, after the redemption and prior
to the release of the proceeds,  no appreciation  or depreciation  will occur in
the value of the redeemed shares, and no interest will be paid on the redemption
proceeds.  If the payment of a redemption check has been delayed, the check will
be mailed promptly after good payment has been collected.

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

  You  may  also  redeem  your  shares  through  broker-dealers.  The  Principal
Underwriter,  acting as agent  for the Fund,  stands  ready to  repurchase  Fund
shares upon orders from dealers at the redemption value described above computed
on  the  day  the  Principal  Underwriter  receives  the  order.  The  Principal
Underwriter will pay the redemption proceeds, less any applicable deferred sales
charge,  to the  broker-dealer  placing the order within  seven days  thereafter
assuming it has received proper documentation. The Principal Underwriter charges
no fees for this service, but your broker-dealer may do so.

  For your protection,  SIGNATURES ON CERTIFICATES, STOCK POWERS AND ALL WRITTEN
ORDERS OR  AUTHORIZATIONS  MUST BE GUARANTEED BY A U.S. STOCK EXCHANGE MEMBER, A
BANK OR OTHER  PERSONS  ELIGIBLE TO GUARANTEE  SIGNATURES  UNDER THE  SECURITIES
EXCHANGE  ACT OF 1934 AND  KIRC'S  POLICIES.  The Fund and KIRC may  waive  this
requirement,  but may  also  require  additional  documents  in  certain  cases.
Currently,  the  requirement  for a  signature  guarantee  has  been  waived  on
redemptions of $50,000 or less where the account  address of record has been the
same for a minimum  period of 30 days.  The Fund and KIRC  reserve  the right to
withdraw this waiver at any time.

  If the Fund receives a redemption  order,  but you have not clearly  indicated
the amount of money or number of shares  involved,  the Fund cannot  execute the
order. In such cases, the Fund will request the missing information from you and
process the order on the day such information is received.

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

  In order to insure that  instructions  received  by KIRC are genuine  when you
initiate a telephone  transaction,  you will be asked to verify certain criteria
specific to your  account.  At the  conclusion of the  transaction,  you will be
given a transaction number confirming your request,  and written confirmation of
your   transaction  will  be  mailed  the  next  business  day.  Your  telephone
instructions will be recorded.  Redemptions by telephone are allowed only if the
address and bank account of record have been the same for a minimum period of 30
days.  If you  cannot  reach  the  Fund by  telephone,  you  should  follow  the
procedures for redeeming by mail or through a broker as set forth above.

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

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

GENERAL

  The Fund  reserves the right at any time to  terminate,  suspend or change the
terms of any redemption  method described in this prospectus,  except redemption
by mail, and to impose fees.

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

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

SHAREHOLDER SERVICES

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

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

EXCHANGES
  If you have obtained the  appropriate  prospectus,  you may exchange shares of
the Fund for shares of certain other Keystone  America Funds and Keystone Liquid
Trust ("KLT") as follows:

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

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

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

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

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

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

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

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

  You may exchange shares by calling KIRC at
1-800-343-2898,  by writing KIRC or by calling KARL at 1-800-346-3858.  However,
you must complete the Telephone  Exchanges  section of the  application to enjoy
the telephone  exchange  privileges.  Shares purchased by check are eligible for
exchange  after 15 days.  There is a $10.00 fee for each  exchange,  except that
there  is no fee for  exchange  orders  received  by the Fund  directly  from an
individual shareholder using KARL. If the shares being tendered for exchange are
still  subject to a deferred  sales  charge,  such charge will carry over to the
shares being acquired in the exchange transaction.  The Fund reserves the right,
after 60 days'  notice  to  shareholders,  to  terminate  this  exchange  offer,
including the right to change the fee for each exchange.

  Orders to exchange a certain class of shares of the Fund for the corresponding
class of shares of KLT will be executed by redeeming  the shares of the Fund and
purchasing  the  corresponding  class of shares of KLT at the net asset value of
KLT shares  next  determined  after the  proceeds  from such  redemption  become
available,  which may be up to seven days after  such  redemption.  In all other
cases, orders for exchanges received by the Fund prior to 4:00 p.m. eastern time
on any day the 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.

KEYSTONE AMERICA MONEY LINE

  Keystone  America  Money Line  eliminates  the delay of mailing a check or the
expense of wiring  funds.  You must  request  the  service on your  application.
Keystone  America  Money Line allows you to  authorize  electronic  transfers of
money to  purchase  shares in any amount  and to redeem up to  $50,000  worth of
shares.  You can use Keystone  America Money Line like an "electronic  check" to
move  money  between  your bank  account  and your  account in the Fund with one
telephone call. You must allow two business days after the call for the transfer
to take place. For money recently invested, you must allow normal check clearing
time before redemption proceeds are sent to your bank.

  You may also arrange for systematic  monthly or quarterly  investments in your
Keystone America account.  Once proper authorization is given, your bank account
will be debited to purchase  shares in the Fund.  You will receive  confirmation
from the Principal Underwriter for every transaction.

  To change the amount of a Keystone America Money Line or terminate the service
(which could take up to 30 days), you must write to KIRC, P.O. Box 2121, Boston,
Massachusetts 02106-2121, and include your account number.

AUTOMATIC WITHDRAWAL PLAN
  Under an Automatic  Withdrawal  Plan,  if your account has a value of at least
$10,000,  you may arrange  for regular  monthly or  quarterly  fixed  withdrawal
payments.  Each  payment  must be at  least  $100 and may be as much as 1.5% per
month or 4.5% per  quarter  of the total net asset  value of the Fund  shares in
your account when the  Automatic  Withdrawal  Plan is opened.  Fixed  withdrawal
payments are not subject to a deferred sales charge.  Excessive  withdrawals may
decrease  or  deplete  the value of your  account.  Because of the effect of the
applicable sales charge, a Class A investor should not make continuous purchases
of the Fund's shares while participating in an Automatic Withdrawal Plan.

DOLLAR COST AVERAGING

  Through  dollar cost averaging you can invest a fixed dollar amount each month
or each quarter in any Keystone  America Fund. This results in more shares being
purchased  when the selected  fund's net asset value is relatively low and fewer
shares being purchased when the fund's net asset value is relatively high, which
may cause a lower  average  cost per  share  than a less  systematic  investment
approach.

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

TWO DIMENSIONAL INVESTING
  You may elect to have income and capital gains distributions from any class of
Keystone America Fund shares you may own automatically  invested to purchase the
same class of shares of any other  Keystone  America  Fund.  You may select this
service on the application and indicate the Keystone  America Fund(s) into which
distributions are to be invested.

OTHER SERVICES
  Under  certain  circumstances,  you may,  within 30 days  after a  redemption,
reinstate  your account in the same class of shares that you redeemed at current
net asset value.

PERFORMANCE DATA

  From time to time, the Fund may advertise "total return,"  "current yield" and
a "tax equivalent  yield." ALL FIGURES ARE BASED ON HISTORICAL  EARNINGS AND ARE
NOT INTENDED TO INDICATE FUTURE PERFORMANCE. Total return and yield are computed
separately  for each  class of shares of the Fund.  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 the sales charge and 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 and general mutual
fund industry information for each class of shares when advertising or marketing
the  Fund's  shares,  such  as  data  from  Lipper  Analytical  Services,  Inc.,
Morningstar,  Inc.,  CDS-Weisenberger  and  Value  Line or other  financial  and
industry publications.

FUND SHARES

  Generally,   the  Fund  currently  issues  three  classes  of  shares,   which
participate in dividends and  distributions  and have equal voting,  liquidation
and other rights except that (1) expenses  related to the  distribution  of each
class of shares or other  expenses  that the Board of Trustees may  designate as
class  expenses,  from time to time,  are borne  solely by each class;  (2) each
class of shares has  exclusive  voting  rights with respect to its  Distribution
Plan;  (3) each  class has  different  exchange  privileges;  and (4) each class
generally has a different designation.

  Shareholders are entitled to one vote for each full share owned and fractional
votes  for  fractional  shares.  Shares of the Fund vote  together  except  when
required  by law to vote  separately  by class.  The Fund  does not have  annual
meetings.  The Fund will have special  meetings,  from time to time, as required
under its Declaration of Trust and under the 1940 Act. As provided in the Fund's
Declaration  of Trust,  shareholders  have the right to  remove  Trustees  by an
affirmative  vote of two-thirds of the outstanding  shares. A special meeting of
the  shareholders  will be held  when 10% of the  outstanding  shares  request a
meeting for the  purpose of  removing a Trustee.  The Fund is prepared to assist
shareholders  in  communications  with one another for the purpose of  convening
such 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.  The Fund's  Declaration of Trust
provides,  however,  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.

  The Fund is authorized to issue additional classes or series of shares.

                      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 is given a
     plus (+) designation.

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

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

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

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

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

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

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

    2. nature of and provisions of the obligation; and

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

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

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

D.  BOND RATINGS ARE AS FOLLOWS:
  1. AAA -- Debt rated AAA has the highest rating assigned by S&P. Capacity to
pay interest and repay principal is extremely strong.

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

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

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

MOODY'S CORPORATE AND MUNICIPAL BOND RATINGS

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

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

  The note ratings are as follows:

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

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

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

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

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

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

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

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

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

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

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

FITCH CORPORATE AND MUNICIPAL RATINGS

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

  The note ratings are as follows:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

OPTIONS TRANSACTIONS

  WRITING COVERED OPTIONS.  To the extent  permitted by its investment  policies
and restrictions,  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.  To the extent  permitted by its investment  policies and
restrictions,  the Fund may purchase put or call options,  including  purchasing
put or call options for the purpose of offsetting previously written put or call
options of the same series.

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

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

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

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

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

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

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

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

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

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

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

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

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

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.

                            REDUCED SALES CHARGES

  Initial  sales   charges  may  be  reduced  or   eliminated   for  persons  or
organizations purchasing Class A shares of the Fund alone or in combination with
Class A shares of other Keystone America Funds.

  For  purposes  of  qualifying  for reduced  sales  charges on  purchases  made
pursuant to Rights of  Accumulation or Letters of Intent,  the term  "Purchaser"
includes the following persons: an individual; an individual,  his or her spouse
and children under the age of 21; a trustee or other fiduciary of a single trust
estate  or  single  fiduciary   account   established  for  their  benefit;   an
organization  exempt from federal income tax under Section 501 (c)(3) or (13) of
the Internal Revenue Code; a pension,  profit-sharing  or other employee benefit
plan whether or not qualified under Section 401 of the Internal Revenue Code; or
other organized  groups of persons,  whether  incorporated or not,  provided the
organization  has been in existence for at least six months and has some purpose
other than the purchase of  redeemable  securities  of a  registered  investment
company at a discount.  In order to qualify for a lower sales charge, all orders
from an  organized  group  will  have to be placed  through a single  investment
dealer or other firm and identified as originating from a qualifying purchaser.

CONCURRENT PURCHASES
  For purposes of qualifying for a reduced sales charge, a Purchaser may combine
concurrent  direct  purchases of Class A shares of two or more of the  "Eligible
Funds," as defined  below.  For example,  if a Purchaser  concurrently  invested
$75,000 in one of the other "Eligible  Funds" and $75,000 in the Fund, the sales
charge  would be that  applicable  to a $150,000  purchase,  i.e.,  3.75% of the
offering price, as indicated in the sales charge schedule in the prospectus.

RIGHT OF ACCUMULATION
  In calculating the sales charge  applicable to current purchases of the Fund's
Class A shares, a Purchaser is entitled to accumulate current purchases with the
current  value of  previously  purchased  Class A shares of the Fund and Class A
shares of certain other  eligible funds that are still held in (or exchanged for
shares of and are still held in) the same or another  eligible  fund  ("Eligible
Fund(s)"). The Eligible Funds are the Keystone America Funds and Keystone Liquid
Trust.

  For example,  if a Purchaser  held shares  valued at $99,999 and  purchased an
additional $5,000, the sales charge for the $5,000 purchase would be at the next
lower sales  charge of 3.75% of the  offering  price as  indicated  in the sales
charge  schedule.  KIRC  must be  notified  at the  time of  purchase  that  the
Purchaser is entitled to a reduced sales charge, which reduction will be granted
subject to confirmation of the Purchaser's  holdings.  The Right of Accumulation
may be modified or discontinued at any time.

LETTER OF INTENT
  A Purchaser  may qualify for a reduced  sales  charge on a purchase of Class A
shares of the Fund alone or in  combination  with purchases of Class A shares of
any of the other  Eligible  Funds by completing  the Letter of Intent section of
the  application.  By  so  doing,  the  Purchaser  agrees  to  invest  within  a
thirteen-month  period a specified amount,  that, if invested at one time, would
qualify  for a reduced  sales  charge.  Each  purchase  will be made at a public
offering price applicable to a single transaction of the dollar amount specified
on the application,  as described in this prospectus.  The Letter of Intent does
not  obligate  the  Purchaser  to  purchase,  nor the Fund to sell,  the  amount
indicated.

  After the Letter of Intent is received by KIRC,  each  investment made will be
entitled to the sales charge applicable to the level of investment  indicated on
the  application.  The Letter of Intent may be  back-dated  up to ninety days so
that any  investments  made in any of the Eligible  Funds  during the  preceding
ninety-day  period,  valued  at the  Purchaser's  cost,  can be  applied  toward
fulfillment of the Letter of Intent.  However,  there will be no refund of sales
charges  already paid during the ninety-day  period.  No retroactive  adjustment
will be made if purchases  exceed the amount  specified in the Letter of Intent.
Income and capital gains distributions taken in additional shares will not apply
toward completion of the Letter of Intent.

  If total  purchases  made  pursuant  to the Letter of Intent are less than the
amount specified, the Purchaser will be required to remit an amount equal to the
difference  between the sales  charge paid and the sales  charge  applicable  to
purchases  actually made. Out of the initial purchase (or subsequent  purchases,
if necessary) 5% of the dollar amount  specified on the application will be held
in escrow by KIRC in the form of shares  registered in the Purchaser's name. The
escrowed shares will not be available for redemption, transfer or encumbrance by
the Purchaser until the Letter of Intent is completed or the higher sales charge
paid. All income and capital gains distributions on escrowed shares will be paid
to the Purchaser or his order.

  When the minimum  investment  specified  in the Letter of Intent is  completed
(either prior to or by the end of the thirteen-month period), the Purchaser will
be notified and the escrowed shares will be released. If the intended investment
is not  completed,  the  Purchaser  will be  asked  to  remit  to the  Principal
Underwriter any difference  between the sales charge on the amount specified and
on the amount actually attained.  If the Purchaser does not within 20 days after
written  request by the Principal  Underwriter or his dealer pay such difference
in sales charge,  KIRC will redeem an appropriate  number of the escrowed shares
in order to realize such difference.  Shares remaining after any such redemption
will be released  by KIRC.  Any  redemptions  made by the  Purchaser  during the
thirteen-month  period will be  subtracted  from the amount of the purchases for
purposes of determining whether the Letter of Intent has been completed.  In the
event of a total  redemption of the account prior to completion of the Letter of
Intent,  the  additional  sales charge due will be deducted from the proceeds of
the redemption and the balance will be forwarded to the Purchaser.

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

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

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

         The Fund is an  open-end,  diversified  management  investment  company
commonly  known as a mutual fund.  The Fund seeks the highest  possible  current
income, exempt from federal income taxes, while preserving capital. The Fund was
formed as a  Massachusetts  business  trust on  October  24,  1986.  The Fund is
managed by Keystone  Management,  Inc.  ("Keystone  Management")  and advised by
Keystone Investment Management Company (formerly named Keystone Custodian Funds,
Inc.) ("Keystone").

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

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

         The Fund invests  primarily in municipal  bonds, but also may invest in
certain other securities as described below.

MUNICIPAL BONDS

         Municipal  bonds include debt  obligations  issued by or on behalf of a
state, a territory or a possession of the United States  ("U.S."),  the District
of Columbia or any political subdivision, agency or instrumentality thereof (for
example,  counties, cities, towns, villages,  districts,  authorities) to obtain
funds for various public purposes, including the construction of a wide range of
public facilities, such as airports, bridges, highways, housing, hospitals, mass
transportation,  schools,  streets  and  water  and sewer  works.  Other  public
purposes  for which  municipal  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 fully exempt from federal income
tax. The income of certain types of industrial development bonds used to finance
certain  privately-operated  facilities  (qualified  "private  activity"  bonds)
issued after August 7, 1986,  while exempt from federal  income tax, is included
for the purposes of the calculation of the alternative  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. - Municipal Division  ("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 generally as extensive as those 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.

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

OTHER ELIGIBLE SECURITIES

         The  Fund  may  invest  up  to  20%  of  its  assets   under   ordinary
circumstances and up to 100% of its assets for temporary  defensive  purposes in
the following  types of  instruments:  (1) commercial  paper,  including  master
demand  notes,  that at the date of  investment  is rated A-1 (the highest grade
given by S&P),  Prime-1 (the highest grade given by Moody's) or, if not rated by
such  services,  is issued by a company  that at the date of  investment  has an
outstanding  issue  rated  A or  better  by S&P  or  Moody's;  (2)  obligations,
including certificates of deposit and bankers' acceptances, of banks, or savings
and loan  associations,  having at least $1  billion in assets as of the date of
their most  recently  published  financial  statements  that are  members of the
Federal Deposit Insurance Corporation,  including U.S. branches of foreign banks
and foreign branches of U.S. banks;  (3) corporate  obligations that at the date
of investment are rated A or better by S&P or Moody's; (4) obligations issued or
guaranteed  by the U.S.  government or by any agency or  instrumentality  of the
U.S.  government;  and (5) qualified "private activity"  industrial  development
bonds, the income from which, while exempt from federal income tax under Section
103 of the Code,  is included  in the  calculation  of the  federal  alternative
minimum tax.

FUNDAMENTAL NATURE OF INVESTMENT OBJECTIVE

         The  investment  objective  of the Fund is  fundamental  and may not be
changed  without  approval  of the  holders  of a  majority  as  defined  in the
Investment  Company Act of 1940 ("1940  Act") of the Fund's  outstanding  voting
shares (which means the lesser of (1) 67% of the shares represented at a meeting
at which more than 50% of the  outstanding  shares are  represented  or (2) more
than 50% of the outstanding shares).

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

         The investment restrictions set forth below are fundamental and may not
be changed  without the vote of a 1940 Act  majority  of the Fund's  outstanding
voting shares. Unless otherwise stated, all references to the assets of the Fund
are in terms of current market value. The Fund may not do the following:

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

         (2) purchase  securities on margin except that it may obtain such short
term credit as may be necessary  for the  clearance  of  purchases  and sales of
securities;

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

         (4) borrow money or enter into reverse  repurchase  agreements,  except
that the Fund may enter into reverse repurchase  agreements or borrow money from
banks for temporary or emergency  purposes in aggregate  amounts up to one-third
of the value of the Fund's net assets; provided that while borrowings from banks
(not  including  reverse  repurchase  agreements)  exceed 5% of the  Fund's  net
assets,  any such  borrowings will be repaid before  additional  investments are
made;

         (5) pledge more than 15% of its net assets to secure indebtedness;  the
purchase  or  sale  of  securities  on a  "when  issued"  basis,  or  collateral
arrangement with respect to the writing of options on securities, are not deemed
to be a pledge of assets;

         (6) issue senior  securities;  the purchase or sale of  securities on a
"when  issued" basis or  collateral  arrangement  with respect to the writing of
options on securities, are not deemed to be the issuance of a senior security;

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

         (8) purchase any security  (other than U.S.  government  securities) of
any issuer if as a result more than 25% of its total assets would be invested in
a single industry, 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;

         (9) invest more than 10% of its total assets in  securities  with legal
or  contractual  restrictions  on  resale  or in  securities  for  which  market
quotations are not readily available,  or in repurchase  agreements  maturing in
more than seven days;

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

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

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

         (13) underwrite  securities of other issuers,  except that the Fund may
purchase  securities from the issuer or others and dispose of such securities in
a manner consistent with its investment objective.

         Additional  restrictions  adopted by the Fund,  which may be changed by
the  Board  of  Trustees,  provide  that the Fund  may not  purchase  or  retain
securities of an issuer if, to the knowledge of the Fund, officers,  Trustees or
Directors of the Fund or Keystone each owning  beneficially  more than 1/2 of 1%
of the  securities  of such  issuer  own in the  aggregate  more  than 5% of the
securities of such issuer,  or such persons or management  personnel of the Fund
or Keystone have a  substantial  beneficial  interest in the  securities of such
issuer.  Portfolio  securities of the Fund may not be purchased  from or sold or
loaned to Keystone or any affiliate thereof or any of their Directors,  officers
or employees.

         Although  not  fundamental   restrictions   or  policies   requiring  a
shareholders'  vote to change,  the Fund has  undertaken  to a state  securities
authority that, so long as the state  authority  requires and shares of the Fund
are registered for sale in that state, the Fund (1) will not invest in interests
in oil,  gas or  other  mineral  exploration  or  development  programs,  except
publicly traded  securities of companies  engaging in such activities;  (2) will
not write, purchase or sell puts, calls or combinations thereof,  except that it
may  purchase  "stand-by  commitments"  and  master  demand  notes;  and  (3) in
connection  with the  purchase of debt  securities,  it may acquire  warrants or
other rights to subscribe for  securities of issuers or securities of parents or
subsidiaries  of such issuers  (warrants),  provided that no more than 5% of its
total assets may be invested in warrants  (for the purpose of this  restriction,
warrants attached to securities acquired by the Fund may be deemed to be without
value),  in all cases  unless  authorized  by a vote of a majority of the Fund's
outstanding voting shares.

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

         Although  not  a  fundamental   restriction   or  policy   requiring  a
shareholders'  vote to  change,  the Fund  has  undertaken  to state  securities
authorities  that,  so long as the state  authorities  require and shares of the
Fund are  registered  for sale in those  states,  the Fund  will not  invest  in
securities  (other  than U.S.  government  securities)  of any  issuer  if, as a
result,  more than 5% of its total assets would be invested in  securities  of a
single 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.

         For the purpose of  limitations  1, 10 and 13, 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 multi-state  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  1 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.

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

         Although  not  a  fundamental  restriction  or  a  policy  requiring  a
shareholders'  vote to change,  the Fund has  undertaken  to a state  securities
authority that, so long as the state  authority  requires and shares of the Fund
are  registered  for sale in that  state,  the Fund  will  maintain  300%  asset
coverage with respect to any bank borrowings.

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

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

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

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

         (1)  securities for which market  quotations are readily  available are
valued at the mean of the bid and asked prices at the time of valuation;

         (2) 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;

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

         (4)  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

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

         The Fund  believes that reliable  market  quotations  are generally not
readily  available  for  purposes  of  valuing  municipal  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 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  securities  and certain other  securities.  Non-tax
exempt  securities for which market  quotations are readily available are valued
on a consistent  basis at that price quoted that, in the opinion of the Board of
Trustees  or the  person  designated  by the  Board  of  Trustees  to  make  the
determination,  most  nearly  represents  the  market  value  of the  particular
security.  Any securities for which market  quotations are not readily available
or other assets are valued on a consistent  basis at fair value as determined in
good faith using methods prescribed by the Fund's Board of Trustees.

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

GENERAL

         Generally,  the Fund offers three classes of shares. Class A shares are
offered with a maximum  front end sales  charge of 4.75%  payable at the time of
purchase ("Front End Load Option"). Class B shares purchased on or after June 1,
1995 are subject to a contingent  deferred sales charge payable upon  redemption
during  the 72 month  period  following  the month of  purchase.  Class B shares
purchased  prior to June 1, 1995 are  subject  to a  contingent  deferred  sales
charge payable upon redemption  within four calendar years after purchase ("Back
End Load Option").  Class B shares  purchased on or after June 1, 1995 that have
been outstanding eight years following the month of purchase will  automatically
convert to Class A shares  without  imposition  of a front-end  sales  charge or
exchange  fee.  Class B shares  purchased  prior to June 1,  1995 that have been
outstanding  during  seven  calendar  years  will  similarly  convert to Class A
shares.  (Conversion of Class B shares  represented by stock  certificates  will
require the return of stock  certificates to Keystone  Investor Resource Center,
Inc.,  the Fund's  transfer and dividend  disbursing  agent  ("KIRC").)  Class C
shares are sold  subject to a  contingent  deferred  sales  charge  payable upon
redemption within one year after purchase ("Level Load Option").  Class C shares
are available  only through  dealers who have entered into special  distribution
agreements  with the Principal  Underwriter.  The prospectus  contains a general
description  of how  investors may buy shares of the Fund, as well as a table of
applicable  sales  charges for Class A shares,  a  discussion  of reduced  sales
charges that may apply to subsequent  purchases and a description  of applicable
contingent deferred sales charges.

CONTINGENT DEFERRED SALES CHARGES

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

CLASS A SHARES

         With certain  exceptions,  purchases of Class A shares made on or after
April 10, 1995 (1) in an amount equal to or exceeding $1,000,000 and/or (2) by a
corporate  qualified  retirement plan or a non-qualified  deferred  compensation
plan  sponsored  by a  corporation  having  100 or more  eligible  employees  (a
"Qualifying  Plan"),  in either case without a front-end  sales charge,  will be
subject  to a  contingent  deferred  sales  charge of 1.00%  during the 24 month
period following the date of purchase.  Certain Class A shares purchased without
a front-end  sales charge prior to April 10, 1995 may be subject to a contingent
deferred  sales  charge of 0.25%  upon  redemption  during the  one-year  period
commencing on the date such shares were  originally  purchased.  The  contingent
deferred  sales  charge  will be  retained  by the  Principal  Underwriter.  See
"Calculation of Contingent Deferred Sales Charge" below.

CLASS B SHARES

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

         With certain  exceptions,  the Fund will impose a deferred sales charge
of 3.00% on shares  redeemed during the calendar year of purchase and during the
first calendar year after the year of purchase;  2.00% on shares redeemed during
the  second  calendar  year  after  the year of  purchase;  and  1.00% on shares
redeemed during the third calendar year after the year of purchase.  No deferred
sales charge is imposed on amounts redeemed thereafter.

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

CLASS C SHARES

         With certain exceptions, the Fund may impose a deferred sales charge of
1% on shares  redeemed  within one year after the date of purchase.  No deferred
sales charge is imposed on amounts redeemed thereafter. If imposed, the deferred
sales charge is deducted from the redemption  proceeds otherwise payable to you.
The  deferred  sales  charge  is  retained  by the  Principal  Underwriter.  See
"Calculation of Contingent Deferred Sales Charge" below.

CALCULATION OF CONTINGENT DEFERRED SALES CHARGE

         Any  contingent  deferred  sales charge  imposed upon the redemption of
Class A, Class B or Class C shares is a percentage  of the lesser of (1) the net
asset value of the shares redeemed or (2) the net cost of such shares.

         No contingent  deferred sales charge is imposed when you redeem amounts
derived from (1)  increases  in the value of your account  above the net cost of
such shares due to increases  in the net asset value per share of the Fund;  (2)
certain  shares  with  respect  to which  the Fund did not pay a  commission  on
issuance,  including shares acquired through reinvestment of dividend income and
capital gains  distributions;  (3) certain Class A shares held for more than one
or two years, as the case may be, from the date of purchase;  (4) Class B shares
held during  more than four  consecutive  calendar  years or more than 72 months
after the month of purchase,  as the case may be; or (5) Class C shares held for
more than one year from the date of purchase.

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

WAIVER OF SALES CHARGES

         Shares  of the Fund  also  may be  sold,  to the  extent  permitted  by
applicable law, regulations,  interpretations or exemptions,  at net asset value
without the  imposition  of an initial  sales  charge to (1)  certain  officers,
Directors,  Trustees, full-time employees and sales representatives of the Fund,
Keystone  Management,  Keystone,  Keystone  Investments,  Inc.  (formerly  names
Keystone Group,  Inc.)  ("Keystone  Investments"),  their  subsidiaries  and the
Principal  Underwriter who have been such for not less than ninety days; (2) the
pension  and   profit-sharing   plans  established  by  such  companies,   their
subsidiaries  and  affiliates,  for the  benefit  of their  officers,  Trustees,
Directors,  full-time  employees and sales  representatives;  and (3) registered
representatives of firms with dealer agreements with the Principal  Underwriter,
provided  all such sales are made upon the written  assurance  of the  purchaser
that the purchase is made for investment  purposes and that the securities  will
not be resold except through redemption by the Fund.

         No initial  sales  charge is charged on purchases of shares of the Fund
by a bank or trust company in a single account in the name of such bank or trust
company as trustee if the initial  investment in shares of the Fund, or any fund
in the Keystone Investments Family of Funds, pursuant to this waiver is at least
$500,000 and any  commission  paid at the time of such purchase is not more than
1% of the amount invested.

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

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

- ------------------------------------------------------------------------------
                               DISTRIBUTION PLANS
- ------------------------------------------------------------------------------

         Rule 12b-1 under the 1940 Act permits investment companies, such as the
Fund, to use their assets to bear expenses of distributing  their shares if they
comply  with  various  conditions,  including  adoption of a  distribution  plan
containing certain provisions set forth in the Rule. The Fund's Class A, B and C
Distribution Plans have been approved by the Fund's Board of Trustees, including
a majority of the Trustees who are not interested persons of the Fund as defined
in the 1940 Act ("Independent  Trustees") and the Trustees who have no direct or
indirect  financial  interest in the Distribution  Plan or any agreement related
thereto  (the  "Rule  12b-1  Trustees"  who  are  the  same  as the  Independent
Trustees).  (The Class A, B and C Distribution Plans each a "Distribution Plan,"
and collectively "Distribution Plans.")

         The National Association of Securities Dealers, Inc. ("NASD") currently
limits the amount  that a fund may pay  annually in  distribution  costs for the
sale of its  shares  and  shareholder  service  fees.  The  NASD  limits  annual
expenditures to 1% of the aggregate average daily net asset value of its shares,
of which 0.75% may be used to pay such distribution  costs and 0.25% may be used
to pay shareholder  service fees. The NASD also limits the aggregate amount that
the Fund may pay for such distribution costs to 6.25% of gross share sales since
the inception of the 12b-1 Plan, plus interest at the prime rate plus 1% on such
amounts (less any contingent  deferred sales charges paid by shareholders to the
Principal Underwriter).

CLASS A DISTRIBUTION PLAN

         The Class A  Distribution  Plan provides that the Fund may expend daily
amounts at an annual  rate,  currently  limited  to 0.25% of the Fund's  average
daily net asset value  attributable  to Class A shares,  to finance any activity
that is  primarily  intended to result in the sale of Class A shares,  including
without  limitation,   expenditures   consisting  of  payments  to  a  principal
underwriter  of the Fund  (currently  the Principal  Underwriter)  to enable the
Principal Underwriter to pay or to have paid to others who sell Class A shares a
service  or other  fee,  at such  intervals  as the  Principal  Underwriter  may
determine,   in  respect  of  Class  A  shares  maintained  by  such  recipients
outstanding on the books of the Fund for specified periods.

         Amounts  paid by the  Fund  under  the  Class A  Distribution  Plan are
currently used to pay others, such as dealers, service fees at an annual rate of
up to 0.25% of the average net asset value of Class A shares  maintained by such
recipients outstanding on the books of the Fund for specified periods.

CLASS B DISTRIBUTION PLANS

         The Fund has  adopted  Distribution  Plans for its Class B shares  that
provide that the Fund may expend daily  amounts at an annual rate of up to 1.00%
of the Fund's  average daily net asset value  attributable  to Class B shares to
finance any activity that is primarily intended to result in the sale of Class B
shares,  including,  without limitation,  expenditures consisting of payments to
the principal underwriter of the Fund (currently the Principal  Underwriter) (1)
to enable the Principal  Underwriter to pay to others  (dealers)  commissions in
respect of Class B shares sold since inception of the Distribution Plan; and (2)
to enable the Principal  Underwriter  to pay or to have paid to others a service
fee, at such intervals as the Principal Underwriter may determine, in respect of
Class B shares maintained by any such recipients outstanding on the books of the
Fund for specified periods.

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

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

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

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

CLASS C DISTRIBUTION PLAN

         The Class C  Distribution  Plan provides that the Fund may expend daily
amounts at an annual rate of up to 1.00% of the Fund's  average  daily net asset
value  attributable  to Class C shares to finance any activity that is primarily
intended to result in the sale of Class C shares, including, without limitation,
expenditures  consisting  of payments to the principal  underwriter  of the Fund
(currently the Principal Underwriter) (1) to enable the Principal Underwriter to
pay to others  (dealers)  commissions  in respect  of Class C shares  sold since
inception of the Distribution Plan; and (2) to enable the Principal  Underwriter
to pay or to have  paid to  others  a  service  fee,  at such  intervals  as the
Principal Underwriter may determine,  in respect of Class C shares maintained by
any such recipients outstanding on the books of the Fund for specified periods.

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

DISTRIBUTION PLANS IN GENERAL

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

         The total amounts paid by the Fund under the foregoing arrangements may
not exceed the maximum  Distribution Plan limit specified above, and the amounts
and purposes of expenditures  under a Distribution  Plan must be reported to the
Rule 12b-1  Trustees  quarterly.  The Rule 12b-1 Trustees may require or approve
changes in the  implementation or operation of a Distribution Plan, and may also
require that total  expenditures  by the Fund under a Distribution  Plan be kept
within limits lower than the maximum amount permitted by the  Distribution  Plan
as stated above.

         During the year ended  November 30, 1994,  the Fund paid the  Principal
Underwriter  $269,046,  $241,979 and $279,001  under the Fund's Class A, B and C
Distribution Plans,  respectively.  Unreimbursed distribution expenses under the
Class B and Class C  Distribution  Plans at November  30,  1994 were  $1,996,948
(6.92% of Class B net assets at  November  30,  1994) and  $2,087,302  (8.99% of
Class C net assets at November 30, 1994), respectively.

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

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

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

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

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

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

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

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

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

         Subject to the general  supervision  of the Fund's  Board of  Trustees,
Keystone  Management,  located at 200  Berkeley  Street,  Boston,  Massachusetts
02116-5034,  serves as investment manager to the Fund and is responsible for the
overall  management  of the Fund's  business and affairs.  Keystone  Management,
organized in 1989,  is a  wholly-owned  subsidiary of Keystone and its directors
and principal executive officers have been affiliated with Keystone,  a seasoned
investment  adviser,  for a number of years.  Keystone Management also serves as
investment manager to each of the other 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 (the  "Management  Agreement"),  and subject to the supervision of the
Fund's  Board  of  Trustees,  Keystone  Management  has  agreed  to  manage  and
administer the operation of the Fund and manage the investment and  reinvestment
of the Fund's assets in conformity  with the Fund's  investment  objectives  and
restrictions. The Management Agreement stipulates that Keystone Management shall
provide office space, all necessary office  facilities,  equipment and personnel
in  connection  with its services as well as pay or  reimburse  the Fund for the
compensation  of  Fund  officers  and  Trustees  who  are  affiliated  with  the
investment  manager  and pay all  expenses of  Keystone  Management  incurred in
connection  with its  services.  All  charges  and  expenses  other  than  those
specifically  referred to as being borne by Keystone  Management will be paid by
the Fund,  including,  but not  limited  to,  custodian  charges  and  expenses;
bookkeeping  and  auditors'  charges and  expenses;  transfer  agent charges and
expenses; fees of Independent Trustees; brokerage commissions, brokers' fees and
expenses;  issue and transfer taxes;  costs and expenses under the  Distribution
Plans; taxes and trust fees payable to governmental  agencies; the cost of share
certificates;  fees and expenses of the  registration  and  qualification of the
Fund and its shares  with the  Securities  and  Exchange  Commission  (sometimes
referred  to herein as the "SEC" or the  "Commission")  or under  state or other
securities  laws;  expenses of  preparing,  printing  and mailing  prospectuses,
statements of additional  information,  notices,  reports and proxy materials to
shareholders  of the Fund;  expenses of  shareholders'  and Trustees'  meetings;
charges and  expenses of legal  counsel for the Fund and for the Trustees of the
Fund on matters relating to the Fund;  charges and expenses of filing annual and
other reports with the SEC and other authorities;  and all extraordinary charges
and expenses of the Fund.

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

         Keystone   Management   currently   provides   the  Fund  with  certain
administrative  and management  services,  which services include (1) performing
research  and  planning  with  respect  to (a)  the  Fund's  qualification  as a
regulated  investment  company under Subchapter M of the Code, (b) tax treatment
of the Fund's  portfolio  investments,  (c) tax  treatment of special  corporate
actions (such as reorganizations), (d) state tax matters affecting the Fund, and
(e) the Fund's  distributions  of income and capital  gains;  (2)  preparing the
Fund's  federal  and state tax  returns;  (3)  providing  services to the Fund's
shareholders in connection with federal and state taxation and  distributions of
income and  capital  gains;  and (4)  storing  documents  relating to the Fund's
activities.

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

                                                           Aggregate Net Asset
Management                                                 Value of the Shares
Fee                            Income                              of the Fund
                         2.0% of Gross Dividend
                           and Interest Income
                                   Plus
0.50%    of the first                                      $  100,000,000, plus
0.45%    of the next                                       $  100,000,000, plus
0.40%    of the next                                       $  100,000,000, plus
0.35%    of the next                                       $  100,000,000, plus
0.30%    of the next                                       $  100,000,000, plus
0.25%    of amounts over                                   $  500,000,000;

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

         As a  continuing  condition  of  registration  of  shares  in a  state,
Keystone  Management  has agreed to  reimburse  the Fund  annually  for  certain
operating expenses incurred by the Fund in excess of certain  percentages of the
Fund's  average  daily net assets.  Keystone  Management is not required to make
such  reimbursements to the extent such reimbursement 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 from year to year only if
approved  at least  annually  by the Fund's  Board of Trustees or by a vote of a
majority of the  outstanding  shares,  and such renewal has been approved by the
vote of a  majority  of the  Independent  Trustees  cast in  person at a meeting
called for the purpose of voting on such approval.  The Management Agreement may
be terminated,  without penalty,  on 60 days' written notice by the Fund's Board
of Trustees or by a vote of a majority of  outstanding  shares.  The  Management
Agreement will terminate  automatically  upon its  "assignment"  as that term is
defined in the 1940 Act.

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

* This Trustee may be considered an  "interested  person"  within the meaning of
the 1940 Act.

         Mr. Elfner and Mr. Bissell are "interested  persons" by virtue of their
positions as officers  and/or  Directors of Keystone  Investments and several of
its affiliates including Hartwell Keystone,  the Principal Underwriter and KIRC.
Mr.  Elfner and Mr.  Bissell own shares of Keystone  Investments.  Mr. Elfner is
Chairman  of the  Board,  Chief  Executive  Officer  and  Director  of  Keystone
Investments. Mr. Bissell is a Director of Keystone Investments.

         During the fiscal year ended  November 30, 1994, no Trustee  affiliated
with Keystone or any officer of Keystone  received any direct  remuneration from
the Fund. During the same period the nonaffiliated  Trustees were paid $8,485 in
retainers and fees.  For the 12 month fiscal period ending of November 30, 1994,
fees  paid  to   Independent   Trustees  on  a  fund  complex  wide  basis  were
approximately  $585,975.  On February 28, 1995, the Trustees and officers of the
Fund beneficially owned less than 1% of the Fund's then outstanding shares.

         The address of the Fund's Trustees and officers is 200 Berkeley Street,
Boston, Massachusetts 02116-5034.

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

         Pursuant to a Principal  Underwriting  Agreement dated August 19, 1993,
between the Fund and the Principal  Underwriter (the "Underwriting  Agreement"),
the  Principal  Underwriter  acts  as  the  Fund's  principal  underwriter.  The
Principal  Underwriter,  located at 200 Berkeley Street,  Boston,  Massachusetts
02116-5034,  is a Delaware corporation  wholly-owned by Keystone.  The Principal
Underwriter, as agent, has agreed to use its best efforts to find purchasers for
the shares. The Principal  Underwriter may retain and employ  representatives to
promote  distribution of the shares and may obtain orders from brokers,  dealers
and others, acting as principals,  for sales of shares to them. The Underwriting
Agreement  provides  that the  Principal  Underwriter  will bear the  expense of
preparing,  printing  and  distributing  advertising  and sales  literature  and
prospectuses used by it. In its capacity as principal underwriter, the Principal
Underwriter  may  receive   payments  from  the  Fund  pursuant  to  the  Fund's
Distribution Plans.

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

         The  Fund  has  agreed  under  the  Underwriting  Agreement  to pay all
expenses in connection  with  registration of its shares with the Commission and
auditing and filing fees in connection with registration of its shares under the
various state "blue-sky" laws, and the Principal Underwriter assumes the cost of
sales  literature and preparation of  prospectuses  used by it and certain other
expenses.

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

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

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

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


- ------------------------------------------------------------------------------
                                   BROKERAGE
- ------------------------------------------------------------------------------

         It is the policy of the Fund,  in effecting  transactions  in portfolio
securities,  to seek best execution of orders at the most favorable prices.  The
determination  of what may constitute  best execution and price in the execution
of a securities  transaction  by a broker  involves a number of  considerations,
including,  without  limitation,  the overall direct net economic  result to the
Fund,  involving both price paid or received and any commissions and other costs
paid, the  efficiency  with which the  transaction  is effected,  the ability to
effect the transaction at all where a large block is involved,  the availability
of the broker to stand ready to execute  potentially  difficult  transactions in
the future and the financial  strength and  stability of the broker.  Management
weighs  such  considerations  in  determining  the  overall   reasonableness  of
brokerage commissions paid.

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

         The Fund  expects  that  purchases  and  sales of  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. There usually will be no
brokerage  commissions  paid by the  Fund  for such  purchases.  Purchases  from
underwriters  will  include  the  underwriting  commission  or  concession,  and
purchases from dealers  serving as market makers will include a dealer's mark up
or  reflect  a  dealer's  mark  down.   Where   transactions  are  made  in  the
over-the-counter  market,  the Fund will deal with primary  market makers unless
more favorable prices are otherwise obtainable.

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

         Neither  Keystone  Management,  Keystone  nor the Fund  intend to place
securities  transactions  with any  particular  broker-dealer  or group thereof.
However,  the Fund's Board of Trustees has determined that the Fund may follow a
policy  of  considering  sales  of  shares  as a  factor  in  the  selection  of
broker-dealers to execute portfolio transactions, subject to the requirements of
best execution, including best price, described above.

         The  policy  of the  Fund  with  respect  to  brokerage  is and will be
reviewed  by the  Fund's  Board of  Trustees  from time to time.  Because of the
possibility  of  further  regulatory   developments   affecting  the  securities
exchanges  and brokerage  practices  generally,  the foregoing  practices may be
changed, modified or eliminated.

         Investment  decisions for the Fund are made  independently  by Keystone
Management  or Keystone  from those of the other funds and  investment  accounts
managed by Keystone  Management or Keystone.  It may frequently develop that the
same  investment  decision  is  made  for  more  than  one  fund.   Simultaneous
transactions  are  inevitable  when  the  same  security  is  suitable  for  the
investment  objective  of more  than  one  account.  When  two or more  funds or
accounts  are  engaged  in the  purchase  or  sale  of the  same  security,  the
transactions  are  allocated as to amount in  accordance  with a formula 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.

         During the fiscal years ended  November 30,  1992,  1993 and 1994,  the
Fund did not pay any brokerage commissions.

         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.

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

MASSACHUSETTS BUSINESS TRUST

         The  Fund  is  a  Massachusetts  business  trust  established  under  a
Declaration of Trust dated October 24, 1986, (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. A copy of the  Declaration of Trust was filed as an
exhibit to the Fund's Registration  Statement.  This summary is qualified in its
entirety by reference to the Declaration of Trust.

DESCRIPTION OF SHARES

         The Declaration of Trust authorizes the issuance of an unlimited number
of shares of beneficial  interest of classes of shares, each of which represents
an equal proportionate interest in the Fund with each other share of that class.
Shares are entitled upon liquidation of the Fund to a pro-rata share of the Fund
based on the relative net assets of each class.  Shareholders have no preemptive
or conversion rights.  Shares are transferable,  redeemable and fully assignable
as  collateral.  There  are no  sinking  fund  provisions.  Generally,  the Fund
currently issues three classes of shares,  but may issue  additional  classes or
series of shares.

SHAREHOLDER LIABILITY

         Pursuant  to  certain  decisions  of  the  Supreme  Judicial  Court  of
Massachusetts, shareholders of a Massachusetts business trust may, under certain
circumstances,  be held personally liable as partners for the obligations of the
trust. Even if, however, the Fund were held to be a partnership, the possibility
of the  shareholders  incurring  financial  loss for that reason  appears remote
because the Fund's  Declaration  of Trust (1) contains an express  disclaimer of
shareholder  liability for  obligations of the Fund; (2) requires that notice of
such  disclaimer be given in each  agreement,  obligation or instrument  entered
into  or  executed  by  the  Fund  or  the   Trustees;   and  (3)  provides  for
indemnification  out of Fund property for any shareholder held personally liable
for the obligations of the Fund.

VOTING RIGHTS

         Under the Declaration of Trust the Fund does not hold annual  meetings.
Shares are entitled to one vote per share. Shares generally vote together as one
class on all  matters.  Classes of shares of the Fund have equal  voting  rights
except that each class of shares has exclusive voting rights with respect to its
respective  Distribution  Plan. 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. Shares have non-cumulative  voting rights,
which  means  that the  holders  of more than 50% of the  shares  voting for the
election of Trustees  can elect 100% of the  Trustees to be elected at a meeting
and,  in such  event,  the  holders of the  remaining  50% or less of the shares
voting will not be able to elect any Trustees.

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

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

LIMITATION OF TRUSTEES' LIABILITY

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

         The Trustees have absolute and  exclusive  control over the  management
and  disposition of all assets of the 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.

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

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

         The cumulative total return of Class A of the Fund for the period April
14, 1987 (commencement of investment  operations)  through November 30, 1994 was
47.99%.  The total cumulative return of Class A of the Fund for the one and five
year periods ended November 30, 1994 were (12.19)% and 21.47%, respectively. The
compounded  average  annual rate of return of Class A of the Fund for the period
April 14, 1987 (commencement of investment  operations) to November 30, 1994 was
5.27%.  The compounded  average annual rate of return of Class A of the Fund for
the one and five year periods ended November 30, 1994 were (12.19)% and 3.97%.

         The  cumulative  total  returns  for  Class B and C of the Fund for the
period from February 1, 1993  (inception of Class B and C) through  November 30,
1994 were (4.98)% and (2.39)%,  respectively.  The cumulative  total returns for
Class B and Class C of the Fund for the one year period ended  November 30, 1994
were (11.03)% and (8.52)%,  respectively. The compounded average annual rates of
return for Class B and Class C for the one year period  ended  November 30, 1994
were (11.03)% and (8.52)%, 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  standardized  yield of
Class A, B and C of the Fund for the 30-day period ended  November 30, 1994 were
5.77%, 5.29% and 5.27%, respectively.

         Tax  equivalent  yield is, in general,  the current  yield divided by a
factor  equal to one minus a stated  income  tax rate and  reflects  the yield a
taxable investment would have to achieve in order to equal on an after-tax basis
a tax-exempt  yield. The federal tax equivalent  yields for Class A, Class B and
Class C shares of the Fund for an  investor  in the 31%  federal tax bracket for
the  30-day  period  ended  November  30,  1994 were  8.36%,  7.67%  and  7.64%,
respectively.

                                    APPENDIX
- --------------------------------------------------------------------------------
                            MONEY MARKET INSTRUMENTS
- --------------------------------------------------------------------------------

     Money market  securities are instruments  with remaining  maturities of one
year  or less  such  as bank  certificates  of  deposit,  bankers'  acceptances,
commercial paper  (including  variable rate master demand notes) and obligations
issued or guaranteed by the U.S. government,  its agencies or instrumentalities,
some of which may be subject to repurchase agreements.

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

A. S&P RATINGS
     An S&P commercial paper rating is a current assessment of the likelihood of
timely  payment of debt  having an  original  maturity of no more than 365 days.
Ratings  are  graded  into four  categories,  ranging  from "A" for the  highest
quality obligations to "D" for the lowest. The top category is as follows:

     1. A:  Issues  assigned  this  highest  rating are  regarded  as having the
     greatest  capacity  for  timely  payment.   Issues  in  this  category  are
     delineated  with the numbers 1, 2 and 3 to indicate the relative  degree of
     safety.

     2. A-1:  This  designation  indicates  that the degree of safety  regarding
     timely  payment  is  either  overwhelming  or  very  strong.  Those  issues
     determined to possess overwhelming safety  characteristics are denoted with
     a plus (+) sign designation.

B. MOODY'S RATINGS
     The term "commercial paper" as used by Moody's means promissory obligations
not having an original  maturity in excess of nine  months.  Moody's  commercial
paper  ratings  are  opinions  of the  ability of  issuers  to repay  punctually
promissory obligations not having an original maturity in excess of nine months.
Moody's  employs the following  designation,  judged to be investment  grade, to
indicate the relative repayment capacity of rated issuers.

     1. The rating Prime-1 is the highest  commercial  paper rating  assigned by
Moody's.  Issuers rated Prime-1 (or related supporting  institutions) are deemed
to have a superior capacity for repayment of short term promissory  obligations.
Repayment  capacity of Prime-1  issuers is normally  evidenced by the  following
characteristics:

     1)   leading market positions in well-established industries;
     2)   high rates of return on funds employed;
     3)   conservative  capitalization structures with moderate reliance on debt
          and ample asset protection;
     4)   broad margins in earnings coverage of fixed financial charges and high
          internal cash generation; and
     5)   well  established  access to a range of financial  markets and assured
          sources of alternate liquidity.

     In assigning  ratings to issuers whose  commercial  paper  obligations  are
supported by the credit of another  entity or entities,  Moody's  evaluates  the
financial strength of the affiliated  corporations,  commercial banks, insurance
companies,  foreign governments or other entities, but only as one factor in the
total rating assessment.

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

   
     Certificates  of  deposit  will  be  limited  to  U.S.   dollar-denominated
certificates  of  U.S.  banks,  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;
or of savings and loan  associations that are members of the Federal Savings and
Loan Insurance  Corporation,  and have at least $1 billion in deposits as of the
date of their most recent financial statements.
    

     The Fund  will not  acquire  time  deposits  or  obligations  issued by the
International Bank for  Reconstruction and Development,  (the "World Bank"), the
Asian Development Bank or the Inter-American Development Bank. Additionally, the
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.

U.S. GOVERNMENT SECURITIES
     Securities issued or guaranteed by the U.S. government include a variety of
Treasury  securities  that differ only in their interest  rates,  maturities and
dates of issuance and  securities  issued by the  Government  National  Mortgage
Association  ("GNMA").  Treasury  bills  have  maturities  of one  year or less.
Treasury notes have  maturities of one to ten years and Treasury bonds generally
have  maturities  of  greater  than  ten  years at the  date of  issuance.  GNMA
securities include GNMA mortgage pass-through certificates.  Such securities are
supported by the full faith and credit of the U.S.

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

     Some obligations of U.S. government agencies and instrumentalities, such as
securities of Federal Home Loan Banks,  are supported by the right of the issuer
to  borrow  from the  Treasury.  Others,  such as bonds  issued  by the  Federal
National Mortgage Association, a private corporation,  are supported only by the
credit of the  instrumentality.  Because the U.S. government is not obligated by
law to provide support to an instrumentality  it sponsors,  the Fund will invest
in  the  securities  issued  by  such  an  instrumentality  only  when  Keystone
determines under standards  established by the Board of Trustees that the credit
risk with respect to the instrumentality does not make its securities unsuitable
investments. U.S. government securities do not include international agencies or
instrumentalities   in   which   the   U.S.   government,    its   agencies   or
instrumentalities participate, such as the World Bank, Asian Development Bank or
the  Inter-American  Development  Bank, or issues insured by the Federal Deposit
Insurance Corporation or Federal Savings and Loan Insurance Corporation.

                      CORPORATE AND MUNICIPAL BOND RATINGS

S&P CORPORATE AND MUNICIPAL BOND RATINGS

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

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

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

     Note ratings are as follows:

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

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

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

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

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

C.  CORPORATE AND MUNICIPAL BOND RATINGS
     An S&P  corporate or municipal  bond rating is a current  assessment of the
credit  worthiness  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 a 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 which 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.

               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 to the Fund or as a hedge  against  changes in the prices of securities
or currencies held by the Fund or to be acquired by the Fund. The Fund's hedging
may  include  sales of  futures  as an offset  against  the  effect of  expected
increases  in interest  or  currency  exchange  rates or  securities  prices and
purchases  of futures as an offset  against the effect of  expected  declines in
interest or currency exchange rates.

     For  example,  when the Fund  anticipates  a  significant  market or market
sector  advance,  it will  purchase a stock  index  futures  contract as a hedge
against not  participating  in such advance at a time when the Fund is not fully
invested.  The purchase of a futures  contract serves as a temporary  substitute
for the  purchase of  individual  securities  which may then be  purchased in an
orderly fashion. As such purchases are made, an equivalent amount of index based
futures contracts would be terminated by offsetting sales. In contrast, the Fund
would sell stock index  futures  contracts  in  anticipation  of or in a general
market or market sector  decline that may  adversely  affect the market value of
the Fund's  portfolio.  To the extent that the Fund's portfolio changes in value
in correlation with a given index,  the sale of futures  contracts on that index
would  substantially  reduce the risk to the  portfolio  of a market  decline or
change in  interest  rates,  and,  by doing so,  provide an  alternative  to the
liquidation  of the Fund's  securities  positions and the resulting  transaction
costs.

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

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

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

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

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

     Currently  interest  rate  futures  contracts  can be  purchased or sold on
90-day U.S.  Treasury  bills,  U.S.  Treasury  bonds,  U.S.  Treasury notes with
maturities between 6 1/2 and 10 years, GNMA  certificates,  90-day domestic bank
certificates  of  deposit,   90-day  Commercial  paper,  and  90-day  Eurodollar
certificates  of  deposit.  It is expected  that  futures  contracts  trading in
additional financial instruments will be authorized.  The standard contract size
is $100,000 for futures  contracts in U.S.  Treasury bonds,  U.S. Treasury notes
and GNMA certificates,  and $1,000,000 for the other designated contracts. While
U.S.  Treasury bonds,  U.S. Treasury bills and U.S. Treasury notes are backed by
the full  faith and  credit of the U.S.  government  and GNMA  certificates  are
guaranteed by a U.S. government agency, the futures contracts in U.S. government
securities are not obligations of the U.S. Treasury.

INDEX BASED FUTURES CONTRACTS

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

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

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

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

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

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

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

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

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

     There can be no assurance, however, that the Fund will be ableto 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 futures  are  similar to options on stocks  except that an
option on a futures  contract  gives the purchaser the right,  in return for the
premium paid, to assume a position in a futures contract (a long position if the
option is a call and a short  position  if the option is a put)  rather  than to
purchase or sell stock,  at a  specified  exercise  price at any time during the
period of the option.  Upon exercise of the option,  the delivery of the futures
position  by the  writer of the  option  to the  holder  of the  option  will be
accompanied  by  delivery of the  accumulated  balance in the  writer's  futures
margin account.  This amount  represents the amount by which the market price of
the  futures  contract at exercise  exceeds,  in the case of a call,  or is less
than,  in the case of a put,  the  exercise  price of the option on the  futures
contract. If an option is exercised the last trading day prior to the expiration
date of the option,  the  settlement  will be made entirely in cash equal to the
difference  between  the  exercise  price of the option and value of the futures
contract.

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

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

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

USE OF NEW INVESTMENT  TECHNIQUES INVOLVING CURRENCY AND OTHER FINANCIAL FUTURES
CONTRACTS OR RELATED OPTIONS
     The Fund may employ new investment  techniques involving currency and other
financial  futures  contracts  and  related  options.  The Fund  intends to take
advantage of new  techniques in these areas which may be developed  from time to
time and which are consistent  with the Fund's  investment  objective.  The Fund
believes that no additional  techniques  have been  identified for employment by
the Fund in the foreseeable future other than those described above.

LIMITATIONS  ON PURCHASE AND SALE OF FUTURES  CONTRACTS  AND RELATED  OPTIONS ON
SUCH FUTURES CONTRACTS
     The Fund will not enter into a futures  contract  if, as a result  thereof,
more than 5% of the Fund's  total  assets  (taken at market value at the time of
entering  into the  contract)  would be  committed  to margin  deposits  on such
futures contracts.

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

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

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

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

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

     At best, the correlation between changes in prices of futures contracts and
of  the  securities  being  hedged  can  be  only  approximate.  The  degree  of
imperfection of correlation  depends upon  circumstances,  such as variations in
speculative  market demand for futures  contracts and for securities,  including
technical  influences  in futures  contracts  trading;  differences  between the
securities being hedged and the financial instruments and indexes underlying the
standard futures contracts  available for trading,  in such respects as interest
rate levels,  maturities  and credit  worthiness  of issuers,  or  identities of
securities  comprising the index and those in the Fund's portfolio.  In addition
futures contract  transactions involve the remote risk that a party be unable to
fulfill its obligations and that the amount of the obligation will be beyond the
ability of the clearing broker to satisfy.  A decision of whether,  when and how
to hedge involves the exercise of skill and judgment,  and even a well-conceived
hedge  may be  unsuccessful  to  some  degree  because  of  market  behavior  or
unexpected interest rate trends.

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

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

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

                         FOREIGN CURRENCY TRANSACTIONS

     The Fund may invest in securities of foreign issuers. When the Fund invests
in foreign securities they usually will be denominated in foreign currencies and
the Fund temporarily may hold funds in foreign currencies.  Thus, the value of a
Fund share will be affected by changes in exchange rates.

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

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

     Currently,  currency  futures  contracts  for the British  Pound  Sterling,
Canadian Dollar, Dutch Guilder, Deutsche Mark, Japanese Yen, Mexican Peso, Swiss
Franc,  and French Franc can be purchased or sold for U.S.  dollars  through the
International  Monetary Market. It is expected that futures contracts trading in
additional  currencies  will be  authorized.  The  standard  contract  sizes are
L125,000  for the  Pound,  125,000  for the  Guilder,  Mark  and  Swiss  Francs,
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,
purchase  of a call option may be less risky than the  ownership  of the foreign
currency or the foreign  securities.  The Fund would purchase a call option on a
foreign  currency to hedge  against an  increase  in the  foreign  currency or a
foreign market advance when the Fund is not fully invested.

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

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

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

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

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

CREDIT RISK
     Whenever the Fund enters into a foreign exchange contract, it faces a risk,
however small, that the counter party 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 credit  worthiness  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  counter  party may be unable or
unwilling to fulfill its  contractual  obligations  as a result of bankruptcy or
insolvency or when foreign exchange controls  prohibit  payment.  In any foreign
exchange transaction,  each party agrees to deliver a certain amount of currency
to the other on a particular  date. In establishing its hedges, a Fund relies on
each contract being completed. If the contract is not performed, then the Fund's
hedge is  eliminated,  and the Fund is exposed to any changes in exchange  rates
since the contract was  originated.  To put itself in the same position it would
have  been in had the  contract  been  performed,  the Fund  must  arrange a new
transaction.  However, the new transaction may have to be arranged at an adverse
exchange  rate.  The trustee for a bankrupt  company may elect to perform  those
contracts 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  counter  party  earlier  in the day than it will be  credited  with
dollars in New York. In the intervening  hours, the buyer can go into bankruptcy
or can be  declared  insolvent.  Thus,  the dollars may never be credited to the
Fund.

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

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

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

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

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

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

NOTES TO SCHEDULE OF INVESTMENTS:

(a) Effective yield is the yield at which the bond accretes on an annual
basis until its maturity date. All zero coupon bonds are non-callable.

(b) Security is a variable or floating rate instrument with periodic demand
features. The Fund is entitled to full payment of principal and accrued
interest upon surrendering the security to the issuing agent according to the
terms of the demand features.

(c) All or a portion of these securities are restricted (i.e., securities
which may not be publicly sold without registration under the Federal
Securities Act of 1933) which are valued at fair value in the opinion of
management--in the case of bonds, at estimated value considering quality,
coupon, term, call feature, yield to maturity of the security and similar
issues which are actively traded, sinking fund, marketability, plus
adjustment, if any, for equity features or other special factors. The Fund
may make investments in an amount up to 10% of the value of the Fund's net
assets in such securities. Dates of acquisition and costs are set forth in
parentheses after the titles of the restricted securities. On the date of
acquisition there was no market quotation or similar securities and the above
securities were valued at acquisition costs. At November 30, 1994, the fair
value of these restricted securities was $947,200 (0.6% of net assets). The
Fund will not pay the costs of disposition of the above restricted securities
other than ordinary brokerage fees, if any.

(d) The cost of investments for federal tax purposes amounted to
$152,232,717. Gross unrealized appreciation and depreciation of investments,
based on identified tax cost, at November 30, 1994 are as follows:


Gross unrealized appreciation                                 $ 2,216,503
Gross unrealized depreciation                                  (9,496,476)
Net unrealized depreciation                                  ($ 7,279,973)

NOTES TO FINANCIAL STATEMENTS

(1.) Significant Accounting Policies

Keystone America Tax Free Income Fund (the "Fund") is a Massachusetts
business trust for which Keystone Management, Inc. ("KMI") is the Investment
Manager and Keystone Custodian Funds, Inc. ("Keystone") is the Investment
Adviser. The Fund was organized on October 24, 1986 and had no operations
prior to February 13, 1987. It is registered under the Investment Company Act
of 1940 as a diversified open-end investment company.

The Fund currently issues three classes of shares. Class A shares are sold
subject to a maximum sales charge of 4.75% payable at the time of purchase.
Class B shares are sold subject to a contingent deferred sales charge payable
upon redemption within three calendar years after the year of purchase. Class
C shares are sold subject to a contingent deferred sales charge payable upon
redemption within one year after purchase. Class C shares are available only
through dealers who have entered into special distribution agreements with
Keystone Distributors, Inc. ("KDI"), the Fund's principal underwriter.

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

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

A. 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 and
market transactions in various relationships between securities in
determining value. Non-tax-exempt securities for which market quotations are
readily available are valued at the price quoted which, in the opinion of the
Board of Trustees or their representative, most nearly represents their
market value. Short-term investments which are purchased with maturities of
sixty days or less are valued at amortized cost (original purchase cost as
adjusted for amortization of premium or accretion of discount) which when
combined with accrued interest approximates market. Short-term investments
maturing in more than sixty days for which market quotations are readily
available are valued at current market value. Short-term investments maturing
in more than sixty days when purchased which are held on the sixtieth day
prior to maturity are valued at amortized cost (market value on the sixtieth
day adjusted for amortization of premium or accretion of discount) which when
combined with accrued interest approximates market. All other securities and
other assets are valued at fair value as determined in good faith using
methods prescribed by the Board of Trustees.

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

Keystone America Tax Free Income Fund

B. Securities transactions are accounted for on the trade date. Realized
gains and losses are recorded on the identified cost basis. Interest income
is recorded on the accrual basis. All premiums and original issue discounts
are amortized/accreted for both financial reporting and federal income tax
purposes. Distributions to shareholders are recorded by the the Fund at the
close of business on the ex-dividend date.

C. The Fund has qualified and intends to qualify in the future as a regulated
investment company under the Internal Revenue Code of 1986, as amended
("Internal Revenue Code"). Thus the Fund is relieved of any federal income
tax liability by distributing all of its net taxable investment income and
net taxable capital gains, if any, to its shareholders. The tax-exempt
interest portion of each dividend is declared uniformly based on the ratio of
the Fund's tax-exempt and taxable income for the entire year. Any
distribution which is declared in December and paid before the next February
1 will be taxable to shareholders in the year declared. The Fund intends to
avoid excise tax liability by making the required distributions under the
Internal Revenue Code.

D. 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 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.

E. The Fund distributes net investment income monthly and net capital gains,
if any, annually. Distributions from net investment income are based on tax
basis net income. From time to time the Fund may distribute dividends which
exceed book basis net income. Excess distributions were previously charged to
paid-in capital. Effective December 1, 1993, the Fund adopted Statement of
Position 93-2: Determination, Disclosure, and Financial Statement
Presentation of Income, Capital Gain and Return of Capital Distributions by
Investment Companies. As a result of this statement, the Fund changed the
classification of distributions to shareholders to better disclose the
differences between financial statement amounts and distributions determined
in accordance with income tax regulations. Accordingly, the following
reclassifications have been made as of November 30, 1993: an increase in paid
in capital of $132,111, an increase in accumulated distributions in excess of
investment income--net of $326,527, and an increase in accumulated realized

<PAGE>

gain (loss) on investments--net of $194,416. Differences between book basis
investment income--net available for distribution and tax basis investment
income--net available for distribution are primarily attributable to
differences in the treatment of 12b-1 Distribution Plan charges and tax basis
returns of capital.

(2.) Capital Share Transactions

The Declaration of Trust authorizes the issuance of an unlimited number of
shares of beneficial interest without par value. Transactions in shares of
the Fund were as follows:

Keystone America Tax Free Income Fund

The Fund bears some of the costs of selling its shares under Distribution
Plans adopted with respect to its Class A, Class B and Class C shares.

The Class A Distribution Plan provides for payments which are currently
limited to 0.25% annually of the average daily net asset value of Class A
shares to pay expenses of the distribution of Class A shares. Amounts paid by
the Fund to KDI under the Class A Distribution Plan are currently used to pay
others, such as dealers, service fees at an annual rate of 0.25% of the
average net asset value of shares sold by such others and remaining
outstanding on the books of the Fund for specified periods.

The Class B Distribution Plan provides for payments at an annual rate of
1.00% of the average daily net asset value of Class B shares to pay expenses
of the distribution of Class B shares. Amounts paid by the Fund under the
Class B Distribution Plan are currently used to pay others (dealers) (i) a
commission at the time of purchase normally equal to 3.00% of the value of
each share sold; and/or (ii) service fees currently at an annual rate of
0.25% of the average net asset value of shares sold by such others and
remaining outstanding on the books of the Fund for specified periods.

The Class C Distribution Plan provides for payments at an annual rate of up
to 1.00% of the average daily net asset value of Class C shares to pay
expenses of the distribution of Class C shares. Amounts paid by the Fund
under the Class C Distribution Plan are currently used to pay others
(dealers) (i) a payment at the time of purchase of 1.00% of the value of each
share sold, such payment to consist of a commission in the amount of 0.75%
and the first year's service fee in advance in the amount of 0.25%, and (ii)
beginning approximately fifteen months after purchase, a commission at an
annual rate of 0.75% (subject to applicable limitations imposed by the rules
of National Association of Securities Dealers, Inc.) and service fees at the
annual rate of 0.25% of the average net asset value of shares sold by such
others and remaining outstanding on the books of the Fund for specified
periods.

Each of the Distribution Plans may be terminated at any time by vote of the
Independent Trustees or by a vote of a majority of the outstanding voting
shares of the respective class. However, after the termination of the Class B
Distribution Plan, payments to KDI will continue at the annual rate of 1.00%
of the average daily net asset value of Class B shares, as compensation for
its services which had been earned while the Class B Distribution Plan was in
effect. Unreimbursed distribution expenses at November 30, 1994 were
$719,756.

For the year ended November 30, 1994 the Fund paid KDI $269,046, $241,979 and

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

Agreement with Keystone, dated December 30, 1989, under which Keystone
provides investment advisory and management services to the Fund and receives
for its services an annual fee representing 85% of the management fee

Keystone Tax Free Income Fund
Seeks current income, exempt from federal income taxes, while
preserving capital by investing in high quality municipal bonds.



Dear Shareholder:

We are writing to report to you on activities in Keystone Tax Free Income
Fund for the twelve-month period which ended November 30, 1995.

Performance

Your Fund provided the following returns, including reinvestment of
dividends, for the twelve-month period:

   Class A shares returned 18.71%,

   Class B shares returned 17.84%, and

   Class C shares returned 17.84%.

   Your Fund's strong performance during the fiscal year represented a
significant recovery from the weak municipal bond market environment of 1994.
We were pleased with this performance which resulted in significant price
appreciation for shareholders. This return was in line with municipal bond
benchmarks during the period. We attribute that performance to our careful
credit analysis and the positive performance of the municipal bond market in
1995.

Municipal bond market rebound

This was an unusually strong year for municipal bonds. After an unsettled
market in 1994, patience rewarded municipal bond investors in 1995. Interest
rates declined and bond prices rose as the slow growth economy kept inflation
under control. This 'soft landing' for the economy created a very positive
environment for bond investors, resulting in unusually strong one-year total
returns. The Lehman Municipal Bond Index--a widely recognized benchmark of
municipal bond performance--returned 18.91% for the twelve-month period which
ended November 30, 1995.

   The efforts of the Federal Reserve Board in 1994 to engineer a soft
landing for the U.S. economy appeared to succeed in 1995. Economic growth
slowed throughout the year, inflation remained under control and interest
rates declined--generally favorable indicators for municipal bonds. While
growth slowed, the fiscal condition of many municipalities generally
improved. Limited supply also had a positive influence on the municipal bond
market. New issue supply continued to decline from $298 billion in 1993 to
approximately half that amount in 1995.

Portfolio strategy

During the twelve-month period, we emphasized bonds that we believed would
benefit from a declining interest rate environment. We concentrated on
non-callable, discount and zero coupon bonds which typically tend to perform
better when rates decline. This strategy resulted in a lengthening of the
Fund's average maturity to 20 years as of November 30, 1995. We continued to
focus on bonds with maturities in the 20-year area for their attractive
income and lower risk characteristics than longer term bonds. We also
maintained an average portfolio quality of AA- as of November 30, 1995.

Relatively attractive values

Despite the strong performance of municipal bonds in 1995, they remained
attractive versus comparable U.S. Treasury securities. In fact, municipal
bond yields averaged about 93% of the yields on comparable long-term U.S.
Treasury bonds, a historically high level.(1) This meant that many investors
could obtain significantly better yields from municipal bonds than Treasuries
on an after-tax basis.

Outlook

We anticipate a continuation of the positive environment for municipal bonds
over the next twelve months. Interest rates should trend down as the economy
continues to slow and level off. However, we do not expect a recession in
1996. A slow growth environment could result in some price appreciation for
shareholders, but we believe most of the returns should come from income.
Municipal bond supply should remain tight in 1996. With the possibility of
rising demand, we think these factors should continue to provide positive
support for municipal bond prices and your Fund.

   We encourage you to maintain a long-term perspective about your Fund. Over
time, investment returns have tended to even out, rewarding municipal bond
investors who are able to tolerate short-term price fluctuations. This has
been particularly true for investors over the past couple of years. In all
market environments, we will continue to manage Keystone Tax Free Income Fund
to seek valuable tax-free income from a portfolio of quality municipal
obligations.(2)

   We appreciate your continued support of Keystone funds. If you have any
questions or comments, please feel free to write to us.

A Discussion With
Your Fund Manager

Betsy A. Blacher is the senior portfolio manager of your Fund and leads
Keystone's municipal bond investment team. Ms. Blacher is a professional with
16 years of investment experience specializing in municipal bonds. She holds
a Bachelor's degree from Wheaton College in economics and sociology.
Together, with portfolio managers Daniel Rabasco and George Kimball and
analyst David Moore, the team evaluates municipal bonds for Keystone tax free
funds.

Q What does the Fund offer investors?

A The Fund is designed for tax-sensitive investors. It seeks consistent,
attractive income that is exempt from federal income tax.(3) The Fund offers
professional management and diversification by investing in investment grade
municipal bonds. We manage the Fund with careful attention to credit quality
and financial stability.

Q How did municipal bonds perform over the past year?

A Municipal bonds rebounded strongly as a slowing economy reduced the threat
of higher interest rates and inflation. Most bond holders more than recovered
from their losses in 1994 and recorded double-digit total returns. This was a
reversal from 1994 when yields rose and bond prices declined. As growth
moderated at the start of 1995, municipal bonds rallied resulting in
unusually positive total returns.

Q How did the Fund perform?

A The Fund generated returns that paralleled the strong performance of the
municipal bond market. At the beginning of 1995 we expected economic growth
to moderate and interest rates to decline. So, we emphasized bonds that we
expected to benefit from declining rates: non-callable, discount and zero
coupon bonds. Since callable bonds are likely to be bought back by the issuer
in this type of environment, we emphasized noncallable bonds to preserve
income as rates declined. At the same time, these bonds became expensive
relative to other municipal bonds and this contributed to the Fund's price
appreciation.

   Discount bonds are sold at a discount from par, or value at maturity.
Historically these bonds have tended to provide more price appreciation in a
falling rate environment than bonds priced close to or above par.

   Zero coupon bonds represented a small portion of the portfolio. But, these
bonds were important contributors to the Fund's strong price recovery.
Because zeroes pay income at maturity, they have historically tended to be
the most sensitive to changes in interest rates. As rates declined, they were
among the best performing holdings in the portfolio.

   We were pleased with the results of this strategy which helped the Fund
participate in the strong recovery of municipal bonds this year.

Q Total returns were impressive, but municipal bond yields declined. Why?

A Yields declined for nearly every municipal bond investor, including
Keystone Tax Free Income Fund. Slower economic growth lessens the potential
for higher inflation which reduces net bond yields. We held a number of high
coupon bonds and attempted to lock-in income by emphasizing selected
non-callable bonds. While the Fund's income still declined, we believe the
portfolio's holdings of these bonds helped the portfolio to maintain income.

Keystone Tax Free Income Fund

In evaluating bonds for the Fund, Keystone looks for . . .

(bullet) Strong credit ratings; bonds rated in the top 4 categories (AAA, AA,
         A, BBB)
(bullet) Responsible fiscal policies
(bullet) Solid financial positions
(bullet) Attractive values

Keystone's municipal bond team also evaluates local economic conditions, the
state legislative climate, the taxing power of the issuer and expected cash
flows from the project.

Q Did talk about a 'flat tax' in Washington affect municipal bonds?

A Discussions about a 'flat tax' limited performance that otherwise would have
been stronger than the impressive returns of 1995. The 'flat tax' would have
been a negative for municipal bonds because it would have taxed municipal
bond income. At this writing, the possibility of such a tax appears remote.
But, the mere discussion of it caused municipal bonds to rise less in price
than comparable U.S. Treasuries. As a result, we believe that municipals are
still attractive values.

Q What is your outlook?

A We continue to be cautiously optimistic about the municipal bond market. We
expect the economy to continue slowing to a sustainable, non-inflationary
level. This should provide the potential for stable to declining interest
rates over the next six months. In particular, we expect short-term interest
rates to decline further, which could result in some price appreciation.

Q Why do you think growth will remain slow?

A Demographics are important to economic growth. With new home sales and new
family formation slowing, we think economic growth should remain moderate
compared to the 1980s and early 1990s. In addition, world economic growth is
a factor. In Europe, growth has been slow, even with cuts in interest rates.
Because U.S. growth is increasingly dependent on world growth, economic
growth should not be a threat to bond investors for some time. Combined with
a proposal to balance the federal budget, these could be strong positives for
municipal bond investors over the long term.

Q What should shareholders expect?

A We think shareholders should not expect a repeat of the unusually positive
performance of 1995; investors should look forward to returns to come
primarily from income rather than price appreciation in the months ahead.

Q Are municipal bond funds still a good value?

A Even after such a great year, we believe municipal bond yields are still
very attractive values compared to taxable bond yields. On November 30 the
yield on a 30-year AA-rated municipal bond equaled 93% of the yield on a
comparable U.S. Treasury bond. As rates declined, taxable bond yields
declined more than tax free yields. This increased the attractiveness of
municipal bonds compared to taxable bonds. As a result, the after-tax yield
of municipal bonds remains relatively high by historical standards.

Class A share performance is from the commencement of investment operations
on April 14, 1987. Performance is reported at the current maximum front-end
sales charge of 4.75%.

   Class B share performance is from the commencement of investment
operations on February 1, 1993. Shares purchased after June 1, 1995 are
subject to a contingent deferred sales charge (CDSC) that declines from 5% to
1% over six years from the month purchased. Performance assumes that shares
were redeemed after the end of a one-year holding period and reflects the
deduction of a 4% CDSC.

   Class C share performance is from the commencement of investment
operations on February 1, 1993. Performance reflects the return you would
have received for holding shares for one year and redeeming after the end of
the period.

   The investment return and principal value will fluctuate so that your
shares, when redeemed, may be worth more or less than the original cost.

   You may exchange your shares for another Keystone fund by phone or in
writing for a $10 fee. The exchange fee is waived for individual investors
who make an exchange using Keystone's Automated Response Line (KARL). The
Fund reserves the right to change or terminate the exchange offer.

- --------------------------------------------------------------------------------
   This chart graphically compares your Fund's total return performance to
certain investment indexes. It is the result of fund performance guidelines
issued by the Securities and Exchange Commission. The intent is to provide
investors with more information about their investment.

Components of the Chart

The chart is composed of three lines that represent the accumulated value of
an initial $10,000 investment for the period indicated. The lines illustrate
a hypothetical investment in:

1. Keystone Tax Free Income Fund

Your Fund seeks current income, exempt from federal income taxes, while
preserving capital by investing in high quality municipal bonds. The return
is quoted after deducting sales charges (if applicable), fund expenses, and
transaction costs and assumes reinvestment of all distributions.

2. Lehman Municipal Bond Index (LMBI)

The LMBI is a broad-based, unmanaged market index of securities issued by
state and local governments. It represents the price change and coupon income
of several thousand securities with various maturities and qualities.
Securities are selected and compiled by Lehman Brothers, Inc. according to
criteria that may be unrelated to your Fund's investment objective.

3. Consumer Price Index (CPI)

The CPI is a widely recognized measure of the cost of goods and services
produced in the U.S. The index contains factors such as the prices of
services, housing, food, transportation and electricity which are compiled by
the U.S. Bureau of Labor Statistics. The CPI is generally considered a
valuable benchmark for investors who seek to outperform increases in the cost
of living.

   The indexes do not include transaction costs associated with buying and
selling securities, and do not hold cash to meet redemptions. It would be
difficult for most individual investors to duplicate these indexes.

Understanding What the Chart Means

The chart demonstrates your Fund's total return performance in relation to a
well known investment index and to increases in the cost of living. It is
important to understand what the chart shows and does not show.

   This illustration is useful because it charts Fund and index performance
over the same time frame and over a long period. Long-term performance is a
more reliable and useful measure of performance than measurements of
short-term returns or temporary swings in the market. Your financial adviser
can help you evaluate fund performance in conjunction with the other
important financial considerations such as safety, stability and consistency.

<PAGE>



Keystone Tax Free Income Fund

Limitations of the Chart

The chart, however, limits the evaluation of Fund performance in several
ways. Because the measurement is based on total returns over an extended
period of time, the comparison often favors those funds which emphasize
capital appreciation when the market is rising. Likewise, when the market is
declining, the comparison usually favors those funds which take less risk.

Performance Can Be Distorted

Funds which are more conservative in their orientation and which place an
emphasis on capital preservation will tend to compare less favorably when the
market is rising. In addition, funds which have income as one of their
objectives also will tend to compare less favorably to relevant indexes.

   Indexes may also reflect the performance of some securities which a fund
may be prohibited from buying. A bond fund, for example, may be limited to
investments in only high quality bonds, or a stock fund may only be able to
buy stocks that have been traded on a stock exchange for a minimum number of
years or of a certain company size. Indexes usually do not have the same
investment restrictions as your Fund.

Indexes Do Not Include Costs of Investing

The comparison is further limited in its utility because the indexes do not
take into account any deductions for sales charges, transaction costs or
other fund expenses. Your Fund's performance figures do reflect such
deductions. Sales charges--whether up-front or deferred--pay for the cost of
the investment advice of your financial adviser. Transaction costs pay for
the costs of buying and selling securities for your Fund's portfolio. Fund
expenses pay for the costs of investment management and various shareholder
services. None of these costs are reflected in index total returns. The
comparison is not completely realistic because an index cannot be duplicated
by an investor--even an unmanaged index--without incurring some charges and
expenses.

One of Several Measures

The chart is one of several tools you can use to understand your investment.
It should be read in conjunction with the Fund's prospectus, and annual and
semiannual reports. Also, your financial adviser, who understands your
personal financial situation, can best explain the features of your Keystone
fund and how it applies to your financial needs.

Future Returns May Be Different

Shareholders also should be mindful that the long-run performance of either
the Fund or the indexes is not representative of what shareholders should
expect to receive from their Fund investment in the future; it is presented
to illustrate only past performance and is not a guarantee of future returns.

Keystone Tax Free Income Fund

NOTES TO FINANCIAL STATEMENTS

(1.) Significant Accounting Policies

Keystone Tax Free Income Fund (formerly Keystone America Tax Free Income
Fund) ("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 was organized on October 24, 1986 and had no
operations prior to February 13, 1987. It is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as a diversified open-end
investment company.

   The Fund currently issues three classes of shares. Class A shares are sold
subject to a maximum sales charge of 4.75% payable at the time of purchase.
Class B shares are sold subject to a contingent deferred sales charge which
varies depending on when shares were purchased and how long they have been
held. Class C shares are sold subject to a contingent deferred sales charge
payable upon redemption within one year of purchase, and available only
through dealers who have entered into special distribution agreements with
Keystone Investment Distributors Company (formerly Keystone Distributors,
Inc.) ("KIDC"), the Fund's principal underwriter.

   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 members of current and
former members of management of Keystone and its affiliates.

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

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



                                       21

NOTES TO FINANCIAL STATEMENTS

101% of the repurchase price. The Fund monitors the value of the collateral
on a daily basis, and if the value of the collateral falls below required
levels, the Fund intends to seek additional collateral from the seller or
terminate the repurchase agreement. If the seller defaults, 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 of 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.

   Pursuant to an exemptive order issued by the Securities and Exchange
Commission, the Fund, along with certain other Keystone funds, may transfer
uninvested cash balances into a joint trading account. These balances are
invested in one or more repurchase agreements that are fully collateralized
by U.S. Treasury and/or Federal Agency obligations.

C. The Fund may enter into currency or financial futures contracts as a hedge
against changes in interest or currency exchange rates. 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 the Fund's taxable income. In addition to market risk,
the Fund is subject to the credit risk that the other party will not complete
the obligations of the contract.

D. When-issued or delayed delivery transactions arise when securities or
currencies are purchased or sold by a Fund with payment and delivery taking
place in the future in order to secure what is considered to be an
advantageous price and yield to the Fund at the time of entering into the
transaction. A separate account of liquid assets equal to the value of such
purchase commitments will be maintained until payment is made. When-issued
and delayed delivery agreements are subject to risks from changes in value
based upon changes in the level of interest rates and other market factors,
both before and after delivery.

E. Securities transactions are accounted for no later than one business day
after 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.

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

NOTES TO FINANCIAL STATEMENTS

G. The Fund declares dividends from net investment income monthly and
distributes to its shareholders such dividends monthly. The Fund declares and
distributes all net realized long-term capital gains, if any, at least
annually. Distributions are determined in accordance with income tax
regulations. Distributions from tax basis net investment income and net
capital gains can exceed book basis net investment income and net capital
gains. Differences between book basis investment income distributions and tax
basis investment income distributions are primarily attributable to
differences in the treatment of 12b-1 Distribution Plan charges and tax basis
returns of capital.

(2.) Capital Share Transactions

The Declaration of Trust authorizes the issuance of an unlimited number of
shares of beneficial interest without par value. Transactions in shares of
the Fund were as follows:

======================================================

   The Fund bears some of the costs of selling its shares under a
Distribution Plan adopted with respect to its Class A, Class B, and Class C
shares pursuant to Rule 12b-1 under the 1940 Act.

   The Class A Distribution Plan provides for payments at an annual rate of
0.25% of the average daily net asset value of Class A shares to pay expenses
for the distribution of Class A shares. Amounts paid by the Fund to KIDC
under the Class A Distribution Plan are currently used to pay others (such as
dealers), service fees at an annual rate of 0.25% of the average net asset
value of Class A shares maintained by such others and remaining outstanding
on the books of the Fund for specified periods.

   The Class B Distribution Plan provides for payments at an annual rate of
up to 1.00% of the average daily net asset value of Class B shares to pay
expenses for the distribution of Class B shares. Amounts paid by the Fund
under the Class B Distribution Plan are currently used to pay others
(dealers) a commission at the time of purchase normally equal to 4.00% of the
price paid for each Class B share sold plus the first year's service fee in
advance in the amount of 0.25% of the price paid for each Class B share sold.
Beginning approximately 12 months after the purchase of a Class B share, the
dealer or other party will receive



                                       23

Keystone Tax Free Income Fund

NOTES TO FINANCIAL STATEMENTS

service fees at an annual rate of 0.25% of the average daily net asset value
of each Class B shares maintained by such others and remaining outstanding on
the Fund's books for specified periods. A contingent deferred sales charge
will be imposed, if applicable, on Class B shares purchased after June 1,
1995 at rates ranging from a maximum of 5% of amounts redeemed during the
first twelve months following the date of purchase to 1% of amounts redeemed
during the sixth twelve month period following the date of purchase. Class B
shares purchased on or after June 1, 1995 that have been outstanding for
eight years following the month of purchase will automatically convert to
Class A shares without a front-end sales charge or exchange fee. Class B
shares purchased prior to June 1, 1995 will retain their existing conversion
rights.

   The Class C Distribution Plan provides for payments at an annual rate of
up to 1.00% of the average daily net asset value of Class C shares to pay
expenses for the distribution of Class C shares. Amounts paid by each Fund
under the Class C Distribution Plan are currently used to pay others
(dealers) a commission at the time of purchase normally equal to 0.75% of the
price paid for each share sold plus the first year's service fee in advance
in the amount of 0.25% of the price paid for each Class C share. Beginning
approximately 15 months after purchase date, the dealer or other party will
receive a commission at an annual rate of 0.75% (subject to applicable
limitations imposed by a rule of the National Association of Securities
Dealers, Inc. ("NASD Rule")) plus service fees at an annual rate of 0.25%,
respectively, of the average net asset value of each Class C share sold by
such others and remaining outstanding on the books of the Fund for specified
periods.

   Each of the Distribution Plans may be terminated at any time by vote of
the Independent Trustees or by a vote of a majority of the outstanding voting
shares of the respective class. However, after the termination of any of the
Distribution Plans, at the discretion of the Board of Trustees, payments to
KIDC may continue as compensation for its services which had been earned
while the Distribution Plan was in effect.

   For the year ended November 30, 1995, the Fund paid KIDC $229,818,
$320,355 and $216,296, pursuant to the Fund's Class A, Class B and Class C
Distribution Plans, respectively.

   Under the NASD Rule, the maximum uncollected amounts for which KIDC may
seek payment from the Fund under its Class B Distribution Plans at November
30, 1995 are $1,945,004 for shares purchased prior to June 1, 1995 and
$162,557 for shares purchased on or after June 1, 1995. The maximum
uncollected amounts for which KIDC may seek payment from the Fund under its
Class C Distribution Plans is $2,197,650 as of November 30, 1995.

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

(3.) Securities Transactions

As of November 30, 1995, the Fund had capital loss carryovers for federal
income tax purposes of approximately $6,698,000 which expire as follows:
2002-$5,831,000, 2003-$867,000.

   Cost of purchases and proceeds from sales of investment securities,
excluding short-term securities, during the year ended November 30, 1995 were
$44,461,072 and $63,089,275, respectively.

NOTES TO FINANCIAL STATEMENTS

(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 at a
rate of 2.0% of the Fund's gross investment income plus an amount determined
by applying annual percentage rates, which start at 0.50% and decline to
0.25% as net assets increase, 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 November 30, 1995, the
Fund paid or accrued to Keystone investment management and administrative
service fees of $919,802 which represented 0.61% of the average net assets of
the Fund. Of such amount paid to KMI, $781,832 was paid to Keystone for its
services to the Fund.

   Keystone Investor Resource Center, Inc. ("KIRC"), a wholly-owned
subsidiary of Keystone, serves as the Fund's transfer agent. During the year
ended November 30, 1995, the Fund paid or accrued to KIRC $211,525 for
transfer agent fees.

   During the year ended November 30, 1995, the Fund paid or accrued to KII
$19,338 for certain accounting services.

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

   The Fund has entered into an expense offset arrangement with its
custodian. For the year ended November 30, 1995, the Fund paid custody fees
in the amount of $78,426 and received a credit of $20,278 pursuant to the
expense offset arrangement, resulting in a total expense of $98,704. The
assets deposited with the custodian under this expense offset arrangement
could have been invested in an income-producing asset.

   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.

(5.) Distributions to Shareholders

Distributions of $0.043, $0.037 and $0.037 per share were declared payable
January 5, 1996 to shareholders of record on December 22, 1995 for Class A,
Class B and Class C shares, respectively. These distributions are not
reflected in the accompanying financial statements.

and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits provide
a reasonable basis for our opinion.

KEYSTONE STATE TAX FREE FUND
PROSPECTUS MAY 31, 1995
AS SUPPLEMENTED JUNE 1, 1995

  Keystone State Tax Free Fund (formerly  named Keystone  America State Tax Free
Fund) (the  "FUND") is a mutual fund that  currently  consists of five  separate
series of shares  evidencing  interests in different  portfolios  of  securities
("Fund(s)"):  the Keystone Florida Tax Free Fund ("Florida Fund"),  the Keystone
Massachusetts  Tax Free  Fund  ("Massachusetts  Fund"),  the  Keystone  New York
Insured Tax Free Fund ("New York Insured Fund"),  the Keystone  Pennsylvania Tax
Free Fund  ("Pennsylvania  Fund") and the  Keystone  Texas Tax Free Fund ("Texas
Fund").

  Each of the Funds  seeks the  highest  possible  current  income  exempt  from
federal income taxes, while preserving  capital.  In addition,  each Fund, other
than the Florida Fund and the Texas Fund,  also seeks to provide a maximum level
of income to its  shareholders  that is exempt from the personal income taxes of
the state for which such Fund is named.

  The Florida Fund also seeks to hold securities exempt from Florida  intangible
taxes. At the present time, Florida does not impose a personal income tax.

  The New York Insured Fund also seeks to hold  securities  exempt from New York
City personal income tax.

  The Pennsylvania  Fund also seeks to hold securities  exempt from Pennsylvania
property taxes.

  Texas does not  currently  impose a personal  income  tax.  In the event Texas
enacts a personal  income  tax,  the Texas Fund will seek the  highest  possible
current income exempt from such taxes, while preserving capital.

  Each Fund invests  principally  in municipal  obligations  exempt from federal
income tax and municipal  obligations  issued by the state for which it is named
and its political subdivisions, agencies and instrumentalities.  At least 80% of
the  municipal  securities  in the New York  Insured  Fund's  portfolio  will be
insured as to timely payment of both principal and interest.  All securities not
insured by the issuer will be insured by a  qualified  municipal  bond  insurer.
Each Fund's net asset value per share will  fluctuate  in response to changes in
the market value of its portfolio securities.

  Generally,  each Fund offers  three  classes of shares.  Information  on share
classes and their fee and sales  charge  structures  may be found in each Fund's
fee  table,  "How  to Buy  Shares,"  "Alternative  Sales  Options,"  "Contingent
Deferred Sales Charge and Waiver of Sales  Charges,"  "Distribution  Plans," and
"FUND Shares."

  This prospectus concisely states information about the FUND and its Funds that
you  should  know  before  investing.  Please  read it and  retain it for future
reference.

  Additional  information  about  the  FUND  and its  Funds  is  contained  in a
statement of additional  information dated May 31, 1995, as supplemented June 1,
1995,  which has been filed with the Securities  and Exchange  Commission and is
incorporated  by reference into this  prospectus.  For a free copy, or for other
information  about  the FUND and its  Funds,  write to the  address  or call the

AMOUNTS SHOWN IN THE EXAMPLE SHOULD NOT BE CONSIDERED A REPRESENTATION OF PAST
OR FUTURE EXPENSES. ACTUAL EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN.
- ---------

(1) Class B shares purchased on or after June 1, 1995 convert tax free to Class
    A shares after eight calendar years. See "Class B Shares" for more
    information.

(2) Class C shares are available only through dealers who have entered into
    special distribution agreements with Keystone Investment Distributors
    Company, the Fund's principal underwriter.

(3) The sales charge applied to purchases of Class A shares declines as the
    amount invested increases. See "Alternative Sales Options."

(4) Purchases of Class A shares in the amount of $1,000,000 or more and/or
    purchases made by certain qualifying retirement or other plans are not
    subject to a sales charge, but may be subject to a contingent deferred sales
    charge. See "Class A Shares" and "Contingent Deferred Sales Charge and
    Waiver of Sales Charges" for an explanation of the charge.

(5) There is no fee for individual investors making exchanges over the Keystone
    Automated Response Line ("KARL"). (For a description of KARL, see
    "Shareholder Services.")

(6) Expense ratios are for the fiscal year ended March 31, 1995 after giving
    effect to the reimbursement by Keystone Investment Management Company
    ("Keystone") of expenses in accordance with certain voluntary expense
    limitations. Currently, Keystone has voluntarily limited expenses of Class A
    Shares to 0.75% of average daily net assets until December 31, 1995.
    Similarly, Keystone has voluntarily limited expenses of Class B and C shares
    to 1.50% of average daily net assets of each such class until December 31,
    1995. Keystone is under no obligation to maintain these limits. Absent
    voluntary expense limitations, expense ratios for the fiscal year ended
    March 31, 1995 for the Florida Fund's Class A, B and C shares, respectively,
    would have been 0.95%, 1.68%, and 1.70%.

(7) Long term shareholders may pay more than the economic equivalent of the
    maximum front end sales charges permitted by rules adopted by the National
    Association of Securities Dealers, Inc. ("NASD").

(8) The Securities and Exchange Commission requires use of a 5% annual return
    figure for purposes of this example. Actual returns for the Funds may be
    greater or less than 5%.

AMOUNTS SHOWN IN THE EXAMPLE SHOULD NOT BE CONSIDERED A REPRESENTATION OF PAST

- ---------

(1) Class B shares purchased on or after June 1, 1995 convert tax free to Class
    A shares after eight calendar years. See "Class B Shares" for more
    information.

(2) Class C shares are available only through dealers who have entered into
    special distribution agreements with Keystone Investment Distributors
    Company, the Fund's principal underwriter.

(3) The sales charge applied to purchases of Class A shares declines as the
    amount invested increases. See "Alternative Sales Options."

(4) Purchases of Class A shares in the amount of $1,000,000 or more and/or
    purchases made by certain qualifying retirement or other plans are not
    subject to a sales charge, but may be subject to a contingent deferred sales
    charge. See "Class A Shares" and "Contingent Deferred Sales Charge and
    Waiver of Sales Charges" for an explanation of the charge.

(5) There is no exchange fee for individual investors making exchanges over the
    Keystone Automated Response Line ("KARL"). (For a description of KARL, see
    "Shareholder Services.")

(6) Expense ratios are estimated for the fiscal year ending March 31, 1996 after
    giving effect to the reimbursement by Keystone of expenses in accordance
    with certain voluntary expense limitations. Currently, Keystone has
    voluntarily limited expenses of Class A Shares to 0.75% of average daily net
    assets until December 31, 1995. Similarly, Keystone has voluntarily limited
    expenses of Class B and C shares to 1.50% of average daily net assets of
    each such class until December 31, 1995. The estimated ratios above assume
    Keystone's extension of these expense limits until March 31, 1996, which
    Keystone is under no obligation to do. Absent voluntary expense limitations,
    expense ratios for the fiscal year ending March 31, 1996 for the New York
    Insured Fund's Class A, B and C shares, respectively, are projected to be
    1.59%, 2.35%, and 2.32%.

(7) Long term shareholders may pay more than the economic equivalent of the
    maximum front end sales charges permitted by rules adopted by the National
    Association of Securities Dealers, Inc.

(8) The Securities and Exchange Commission requires use of a 5% annual return
    figure for purposes of this example. Actual return for the Funds may be
    greater or less than 5%.

THE FUND AND ITS FUNDS

  The FUND is a non-diversified  open-end management investment company commonly
known as a mutual fund. The FUND was formed as a Massachusetts business trust on
September  13,  1990.  The FUND is one of thirty  funds  managed  or  advised by
Keystone Investment Management Company (formerly named Keystone Custodian Funds,
Inc.) ("Keystone"),  the FUND's investment adviser.  The FUND currently consists
of  five  separate  series  evidencing  interests  in  different  portfolios  of
securities.  The Florida  Fund and the  Pennsylvania  Fund were  established  on
September 19, 1990.  The  Massachusetts  Fund, the New York Insured Fund and the
Texas Fund were  established on February 21, 1992.  Shares of the  Massachusetts
Fund and the New York Insured  Fund were not offered  prior to February 4, 1994.
The FUND may offer additional Funds in the future.

INVESTMENT OBJECTIVES AND POLICIES

INVESTMENT OBJECTIVES

  Each of the Funds  seeks the  highest  possible  current  income  exempt  from
federal income taxes, while preserving capital.

FUNDS' PRINCIPAL INVESTMENTS

  Generally,  under ordinary circumstances,  each Fund invests substantially all
and at least 80% of its assets in federally  tax-exempt  obligations,  including
municipal bonds and notes and municipal tax-exempt  commercial paper obligations
that  are  obligations  issued  by or  on  behalf  of  states,  territories  and
possessions  of the United States  ("U.S."),  the District of Columbia and their
political subdivisions, agencies and instrumentalities,  the interest from which
is exempt from federal income taxes, including the alternative minimum tax. Thus
it is possible that up to 20% of a Fund's assets could be in securities  subject
to the alternative minimum tax and/or in taxable obligations.

  Municipal  bonds include fixed,  variable or floating rate general  obligation
and revenue bonds  (including  municipal lease  obligations,  resource  recovery
bonds and zero coupon bonds).  Municipal notes include tax  anticipation  notes,
bond anticipation notes, revenue anticipation notes and project notes. Municipal
commercial   paper   obligations  are  unsecured   promissory  notes  issued  by
municipalities to meet short term credit needs.

  The FLORIDA FUND seeks, in addition,  to hold  securities  exempt from Florida
intangible taxes.

  The PENNSYLVANIA FUND seeks, in addition,  the highest possible current income
exempt from  Pennsylvania  state and local taxes while preserving  capital.  The
Pennsylvania  Fund  also  seeks  to hold  securities  exempt  from  Pennsylvania
personal property taxes.

  The TEXAS FUND provides,  in addition,  an opportunity for investors to invest
in  municipal  securities  of the State of Texas,  its  political  subdivisions,
agencies and instrumentalities.  Texas currently imposes no personal income tax.
In the event Texas enacts a personal  income tax,  the Texas Fund will seek,  in
addition,  the highest possible current income exempt from Texas personal income
taxes while preserving capital.

FLORIDA FUND

  Under ordinary  circumstances,  the Florida Fund invests substantially all and
at least 80% of its assets in municipal  obligations  exempt from federal  taxes
and the Florida intangibles tax.

  For a further  discussion of Florida tax  treatment and the factors  affecting
investment in Florida municipal obligations, see Exhibit A.

MASSACHUSETTS FUND

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

  The Massachusetts  Fund invests at least 80% of its assets in investment grade
municipal  obligations -- bonds rated at the date of investment  within the four
highest grades by Standard & Poor's Corporation ("S&P") (AAA, AA, A and BBB), by
Moody's  Investors  Service,  Inc.  ("Moody's")  (Aaa,  Aa, A and Baa), by Fitch
Investors Service, Inc. - Municipal Division ("Fitch") (AAA, AA, A and BBB), or,
if not rated or rated under a different  system,  are of  comparable  quality to
obligations  so rated as  determined  by  Keystone.  Securities  that are in the
lowest investment grade (BBB or Baa) may have speculative  characteristics.  The
Fund may seek to maximize  return with  respect to a portion (not to exceed 20%)
of its assets.  Such maximum  return is ordinarily  associated  with high yield,
high risk  municipal  bonds in the lower  rating  categories  of the  recognized
rating  agencies or that are unrated (high yield bonds).  Such high yield,  high
risk bonds generally  involve greater  volatility of price and risk of principal
and income  than bonds in the higher  rating  categories  and are,  on  balance,
considered predominantly  speculative.  High yield bonds are also commonly known
as "junk bonds."

  For a further  discussion  of  Massachusetts  tax  treatment  and the  factors
affecting investment in Massachusetts municipal obligations, see Exhibit A.


NEW YORK INSURED FUND

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

  As more fully  discussed below in the section  entitled  "Insurance," at least
80% of the  municipal  securities  in the  investment  portfolio of the New York
Insured  Fund  will be  insured  as to  timely  payment  of both  principal  and
interest.  The purpose of insuring these investments is to minimize credit risks
associated  with  defaults  in  municipal  securities  owned by the  Fund.  Such
insurance,  however,  does not insure against market risk and therefore will not
guarantee the market value of the securities in the Fund's  portfolio upon which
the net asset value of the Fund's shares is based.

  For a further  discussion of New York tax treatment and the factors  affecting
investment in New York municipal obligations, see Exhibit A.


PENNSYLVANIA FUND

  Under ordinary circumstances,  the Pennsylvania Fund invests substantially all
and at least 80% of its assets in  municipal  obligations  exempt  from  federal
taxes  and  Pennsylvania   state  income  taxes.  The  securities  include  debt
obligations of the Commonwealth of Pennsylvania and its political  subdivisions,
agencies,  authorities  and  instrumentalities  and  debt  obligations  of other
qualifying issuers, such as Puerto Rico and the Virgin Islands. In addition, the
Pennsylvania  Fund  attempts  to invest in  municipal  obligations  exempt  from
Pennsylvania  local  income  taxes and seeks to hold,  on the annual  assessment
date, municipal obligations exempt from Pennsylvania personal property taxes.

  Many of the municipal  obligations in which the  Pennsylvania  Fund intends to
invest generate income that is exempt from Pennsylvania state income taxes.

  For a  further  discussion  of  Pennsylvania  tax  treatment  and the  factors
affecting investment in Pennsylvania municipal obligations, see Exhibit A.


TEXAS FUND

  Under ordinary circumstances,  the Texas Fund invests substantially all and at
least 80% of its assets in municipal  obligations of the State of Texas that are
exempt from federal income taxes. The securities include debt obligations of the
State  of  Texas  and its  political  subdivisions,  agencies,  authorities  and
instrumentalities. Texas does not currently impose an income tax on individuals.

  For a further  discussion  of Texas tax  treatment  and the factors  affecting
investment in Texas municipal obligations, see Exhibit A.

MUNICIPAL OBLIGATIONS

  Municipal  obligations  include debt  obligations  issued by or on behalf of a
political  subdivision of the U.S. or any agency or  instrumentality  thereof to
obtain funds for various public  purposes.  In addition,  municipal  obligations
include certain types of industrial  development  bonds that have been or may be
issued by or on  behalf of public  authorities  to  finance  privately  operated
facilities.  General obligation bonds involve the credit of an issuer possessing
taxing power and are payable from the issuer's  general  unrestricted  revenues.
Their payment may be dependent upon an appropriation by the issuer's legislative
body and may be subject  to  quantitative  limitations  on the  issuer's  taxing
power. Limited obligation or revenue bonds are payable only from the revenues of
a  particular  facility  or class of  facilities  or,  in some  cases,  from the
proceeds of a special excise or other specific revenue source,  such as the user
of the facility.  Since each Fund considers  preservation  of capital as well as
the level of tax-exempt income,  each Fund may realize less income than a mutual
fund willing to expose shareholders' capital to greater risk.

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

  Each Fund,  except the  Massachusetts  Fund,  invests  entirely  in  municipal
obligations  only if at the date of  investment  they are rated  within the four
highest  grades by S&P (AAA, AA, A and BBB), by Moody's (Aaa, Aa, A and Baa), by
Fitch (AAA,  AA, A and BBB) or, if not rated or rated under a different  system,
are of comparable quality to obligations so rated as determined by Keystone.

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

OTHER ELIGIBLE INVESTMENTS

  A Fund may invest up to 20% of its assets under ordinary  circumstances and up
to 100% of its assets for temporary defensive purposes in the following types of
instruments:  (1) commercial  paper,  including master demand notes, that at the
date of  investment  is rated  A-1  (the  highest  grade by S&P),  PRIME- 1 (the
highest  grade by  Moody's)  or, if not rated by such  services,  is issued by a
company  that at the date of  investment  has an  outstanding  issue  rated A or
better by S&P or Moody's; (2) obligations, including certificates of deposit and
bankers'  acceptances,  of banks or savings and loan  associations  that have at
least $1  billion  in assets  as of the date of their  most  recently  published
financial   statements  and  are  members  of  the  Federal  Deposit   Insurance
Corporation,  including U.S.  branches of foreign banks and foreign  branches of
U.S. banks;  (3) corporate  obligations  (maturing in 13 months or less) that at
the date of investment are rated A or better by S&P or Moody's;  (4) obligations
issued or guaranteed by the U.S.  government or by any agency or instrumentality
of the U.S.; (5) qualified "private activity" industrial  development bonds, the
income from which, while exempt from federal income tax under Section 103 of the
Code, is includable in the calculation of the federal  alternative  minimum tax;
and (6)  municipal  obligations,  the income from which is exempt  from  federal
income tax, but not exempt from income tax, personal property tax or intangibles
tax in a state  for  which a Fund is named  and  where  such  taxes  apply.  For
example,  each Fund may assume a temporary  defensive  position upon  Keystone's
determination  that  market  conditions  so  warrant.  If a  Fund  is  investing
defensively, it is not pursuing its investment objectives.

  Each  Fund may  enter  into  repurchase  and  reverse  repurchase  agreements,
purchase and sell securities on a when issued and delayed delivery basis,  write
covered  call and put  options  and  purchase  call and put  options,  including
purchasing call and put options to close out existing positions,  and may employ
new  investment  techniques  with  respect to such  options.  Each Fund may also
engage in financial  futures  contracts  and related  options  transactions  for
hedging  purposes  and  not  for  speculation  and  may  employ  new  investment
techniques  with  respect to such  futures  contracts  and related  options.  In
addition,  each Fund may invest in municipal obligations  denominated in foreign
currencies and may use  subsequently  developed  investment  techniques that are
related to any of its  investment  policies.  None of the Funds are  expected to
enter into repurchase agreements in the ordinary course of business.

  In addition to the options and futures mentioned above, if consistent with its
investment  objectives,  the Fund may also  invest  in  certain  other  types of
"derivative investments," including structured securities.

  For  further  information  about  the  types  of  investments  and  investment
techniques  available  to  the  Funds,   including  the  associated  risks,  see
"Additional  Investment  Information" located at the back of this prospectus and
the statement of additional information.

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

INSURANCE

  At least 80% of the  municipal  securities  in the  portfolio  of the New York
Insured Fund will consist of obligations  that at all times are fully insured as
to the payment of all principal  and interest  when due ("Insured  Securities").
Each Insured  Security in the  portfolio  will be covered by either a "New Issue
Insurance Policy," "Portfolio  Insurance Policy" issued by a qualified municipal
bond insurer,  or a "Secondary  Insurance Policy." The insurance does not insure
against  market risk and  therefore  does not  guarantee the market value of the
securities in the New York Insured Fund's portfolio.  Similarly, because the net
asset value of the New York Insured Fund's shares is based upon the market value
of the securities in the  portfolio,  such insurance does not cover or guarantee
the value of the New York Insured Fund's shares.

NEW ISSUE INSURANCE POLICIES

  New Issue  Insurance  Policies are obtained by the  respective  issuers of the
municipal securities, and all premiums respecting such securities have been paid
in advance by such issuers.  Such policies are  noncancellable and will continue
in force so long as the municipal securities are outstanding, and the respective
insurers remain in business. Since New Issue Insurance Policies remain in effect
as long as the securities are  outstanding,  the insurance may have an effect on
the resale  value of the  Insured  Securities.  Therefore,  New Issue  Insurance
Policies may be  considered  to represent an element of market value with regard
to the Insured  Securities,  but the exact effect,  if any, of this insurance on
such market value cannot be  estimated.  The New York Insured Fund will purchase
municipal  securities subject to New Issue Insurance Policies only if the claims
paying ability of the insurer thereof is rated AAA by S&P or Aaa by Moody's.

PORTFOLIO INSURANCE POLICIES

  Portfolio  Insurance Policies are obtained by the New York Insured Fund from a
qualified  municipal  bond insurer and are effective only so long as the Fund is
in existence, the insurer is still in business and meeting its obligations,  and
the Insured Securities  described in the policy are held by the New York Insured
Fund. Premium rates for each issue of securities covered by the policy are fixed
for the  life of the New York  Insured  Fund and are  periodically  adjusted  to
reflect purchases and sales of covered securities.  The premium on the Portfolio
Insurance  Policy is an item of expense  and will be  reflected  in the New York
Insured  Fund's  average  annual  expenses.  Premiums are paid from the New York
Insured  Fund's  assets and reduce the  current  yield on its  portfolio  by the
amount thereof. The insurer cannot cancel coverage already in force with respect
to Insured  Securities  owned by the New York  Insured  Fund and  covered by the
policy, except for nonpayment of premiums.

SECONDARY INSURANCE POLICIES

  The New York Insured Fund may, at any time,  purchase  Secondary  Insurance on
any  municipal  security  held by the  Fund.  Such  insurance  coverage  will be
noncancellable  and will continue in force so long as the  securities so insured
are  outstanding.  Secondary  Insurance will likely be purchased by the New York
Insured Fund if, in the opinion of Keystone, the market value or net proceeds of
the sale of a  security  by the Fund  would  exceed  the  current  value of such
security (without insurance) plus the cost of such insurance.  When the New York
Insured Fund purchases Secondary  Insurance,  the single premium is added to the
cost basis of the security and is not considered an item of expense of the Fund.
One of the  purposes of such  insurance is to enable the  securities  covered by
such insurance to be sold as "AAA" or "Aaa" rated Insured Securities at a market
price higher than that which might  otherwise be  obtainable  if the  securities
were sold without the  insurance  coverage.  Therefore,  such  insurance  may be
considered  to represent an element of market value of such Insured  Securities,
although the exact effect, if any, on such market value cannot be estimated. Any
difference between the excess of such a security's market value as an AAA or Aaa
rated  security over its market value without such rating,  including the single
premium cost  thereof,  would inure to the New York Insured Fund in  determining
the net capital gain or loss  realized by the Fund upon the sale of such Insured
Security.

FUNDAMENTAL NATURE OF INVESTMENT OBJECTIVES

  The  investment  objectives  of each Fund and the  requirement  that each Fund
invest,  under ordinary  circumstances,  at least 80% of its assets in federally
tax-exempt municipal  obligations that are also exempt from certain taxes in the
state for which it is named, as set forth above,  are fundamental and may not be
changed without the vote of a majority of the affected Fund's outstanding shares
(as defined in the Investment Company Act of 1940 (the "1940 Act")).

INVESTMENT RESTRICTIONS

  Each Fund has adopted the following fundamental restrictions summarized below,
which may not be changed  without the vote of a 1940 Act majority of such Fund's
outstanding  shares.  These  restrictions  and  certain  other  fundamental  and
nonfundamental  restrictions  are  contained  in  the  statement  of  additional
information.  Unless otherwise stated,  all references to a Fund's assets are in
terms of current market value.

  Generally, each Fund may not do the following:

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

  (2) invest more than 10% of its assets in securities with legal or contractual
restrictions  on resale or in  securities  for which market  quotations  are not
readily available, or in repurchase agreements maturing in more than seven days;

  (3) borrow money or enter into reverse repurchase agreements, except that each
Fund may enter into reverse repurchase agreements or borrow money from banks for
temporary  or  emergency  purposes in  aggregate  amounts up to one-third of the
value of the Fund's net assets;  provided that while  borrowings from banks (not
including reverse repurchase agreements) exceed 5% of the Fund's net assets, any
such borrowings will be repaid before additional investments are made; and

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

  The  Funds  are   non-diversified   under  the  federal  securities  laws.  As
non-diversified  funds,  there  is no  restriction  under  the  1940  Act on the
percentage  of assets that may be invested at any time in the  securities of any
one issuer. The Funds intend to comply, however, with the Code's diversification
requirements  and  other  requirements   applicable  to  "regulated   investment
companies"  to ensure  they will not be  subject to U.S.  federal  income tax on
income and capital gain distributions to shareholders.

  For this reason,  each Fund has adopted the investment  restriction  set forth
below,  which may not be changed  without  the  approval  of a  majority  of its
outstanding  shares.  Specifically,  a Fund may not  purchase a security if more
than 25% of the Fund's  total assets  would be invested in the  securities  of a
single   issuer   (other   than   the  U.S.   government,   its   agencies   and
instrumentalities)  or, with respect to 50% of the Fund's total assets,  if more
than 5% of such assets would be invested in the  securities  of a single  issuer
(other than the U.S. government, its agencies and instrumentalities).

  As a matter of  practice,  a Fund  treats  reverse  repurchase  agreements  as
borrowings  for purposes of  compliance  with the  limitations  of the 1940 Act.
Reverse  repurchase  agreements will be taken into account along with borrowings
from  banks for  purposes  of the 5% limit  set  forth in the  third  investment
restriction above.

  The  foregoing  is only a summary of the Funds'  investment  restrictions  and
policies.  See the statement of additional  information for details and the full
text of the Funds' investment restrictions and related policies.

RISK FACTORS

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

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

  To the  extent  the  Funds  are  not  fully  diversified,  they  may  be  more
susceptible to adverse economic,  political or regulatory developments affecting
a  single  issuer  than  would  be the  case  if the  Funds  were  more  broadly
diversified.

  In addition,  the market value of the fixed income  securities in which a Fund
may invest may vary inversely to changes in prevailing interest rates.

MUNICIPAL OBLIGATIONS

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

  From time to time, proposals have been introduced before the U.S. Congress for
the purpose of restricting  or eliminating  the federal income tax exemption for
interest on municipal obligations,  and similar proposals may well be introduced
in the future.  If such a proposal were enacted,  the  availability of municipal
obligations  for investment by each Fund and the value of the Fund's  securities
could be materially  affected.  In such an event,  the FUND would reevaluate its
Funds' investment  objectives and policies and consider changes in the structure
of the Funds or dissolution.

  If and when a Fund invests in municipal  lease  obligations,  the  possibility
exists that a municipality may not appropriate the funds for lease payments. The
FUND's Board of Trustees  will be  responsible  for  determining,  on an ongoing
basis,  the credit  quality  of such  leases,  including  an  assessment  of the
likelihood of cancellation of any such lease.

NONINVESTMENT GRADE BONDS

  The Massachusetts Fund's investment policy allows the Fund to invest a portion
(not to exceed 20%) of its assets in high yield,  high risk municipal bonds. The
degree to which the Fund will hold such  securities  will,  among other  things,
depend upon Keystone's  economic forecast and its judgment as to the comparative
values  offered by high yield,  high risk bonds and higher  quality  bonds.  The
Massachusetts  Fund seeks to invest up to 20% of its assets  aggressively and to
maximize  return over time from a combination  of many factors,  including  high
current  income and  capital  appreciation  from high  yield,  high risk  bonds.
Although the total amount invested in high yield,  high risk securities will not
exceed  20%  of the  assets  of the  Massachusetts  Fund,  the  Fund  may  (as a
non-diversified  fund) invest as much as the entire 20% in the  securities  of a
single issuer. To that extent, the Massachusetts Fund may be more susceptible to
adverse economic, political or regulatory developments affecting a single issuer
than would be the case if the Fund were more broadly diversified.

  Such  aggressive  investing  involves risks that are greater than the risks of
investing  in higher  quality  debt  securities.  These risks are  discussed  in
greater detail below and include risks from (1) interest rate  fluctuation;  (2)
changes in credit status,  including  weaker overall credit condition of issuers
and risks of default; (3) industry,  market and economic risk; (4) volatility of
price  resulting  from  broad  and  rapid  changes  in the  value of  underlying
securities;  and (5) greater  price  variability  and credit  risks of such high
yield,  high  risk  securities  as zero  coupon  bonds and  pay-in-kind  ("PIK")
securities.

  Specifically, investors should be aware of the following:

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

  (2) the value of high yield,  high risk securities may be more  susceptible to
real or perceived adverse economic,  company or industry  conditions than is the
case for higher quality securities;

  (3) adverse market,  credit or economic  conditions could make it difficult at
certain times to sell certain high yield, high risk securities held by the Fund;

  (4) the  secondary  market for high yield,  high risk  securities  may be less
liquid than the secondary market for higher quality securities, which may affect
the  value of  certain  high  yield,  high risk  securities  held by the Fund at
certain times; and

  (5) high  yield,  high risk zero coupon  securities  may be subject to greater
changes  in value due to  market  conditions,  the  absence  of a cash  interest
payment and the tendency of issuers of such  securities  to have weaker  overall
credit conditions than other high yield, high risk securities.

  These  characteristics of high yield, high risk securities make them generally
more appropriate for long term investment.

  If and when a Fund invests in zero coupon  bonds,  the Fund does not expect to
have enough zero coupon bonds to have a material  effect on dividends.  The FUND
has  undertaken  to a state  securities  authority to disclose  that zero coupon
securities  pay no interest to holders prior to maturity,  and that the interest
on these  securities  is  reported  as income to a Fund and  distributed  to its
shareholders.  These  distributions must be made from the Fund's cash assets or,
if necessary, from the proceeds of sales of portfolio securities.  The Fund will
not be able to purchase additional income producing securities with cash used to
make such  distributions,  and its current income ultimately may be reduced as a
result.

  These  risks  provide the  opportunity  for  maximizing  return over time on a
portion of the Massachusetts Fund's assets, but may result in greater upward and
downward  movement  of the net asset  value per share of the Fund.  As a result,
they should be carefully considered by investors.

  The maximum return sought by the Massachusetts  Fund with respect to up to 20%
of its assets is  ordinarily  associated  with  securities  in the lower  rating
categories  of the  recognized  rating  agencies  or with  securities  that  are
unrated.  Such high yield,  high risk securities are generally rated BB or lower
by S&P or Ba or lower by  Moody's.  The Fund may invest in  securities  that are
rated  as  low as D by  S&P  and C- by  Moody's.  These  rating  categories  are
described  in the section of this  prospectus  entitled  "Additional  Investment
Information." The Fund intends to invest in D rated debt only in cases where, in
Keystone's judgment, there is a distinct prospect of improvement in the issuer's
financial position as a result of the completion of reorganization or otherwise.
The Fund may also invest in unrated  securities  that, in  Keystone's  judgment,
offer comparable  yields and risks to those of securities that are rated as well
as non-investment quality zero coupon and PIK securities.

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

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

TAX CONSIDERATIONS

  For a discussion of the tax considerations for each state and special factors,
including the risks  associated with investing in the municipal  securities of a
single state,  see Exhibit A to this  prospectus and Appendix A to the statement
of additional information.

PRICING SHARES

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

  The Funds value municipal obligations on the basis of valuations provided by a
pricing  service,   approved  by  the  FUND's  Board  of  Trustees,  which  uses
information with respect to transactions in bonds, quotations from bond dealers,
market transactions in comparable  securities and various  relationships between
securities in determining value. Each Fund values its short-term  instruments as
follows: short-term instruments with maturities of sixty days or less are valued
at  amortized  cost  (original  purchase  cost as adjusted for  amortization  of
premium or accretion of discount),  which,  when combined with accrued interest,
approximates market; short-term instruments having maturities of more than sixty
days for which market  quotations  are readily  available  are valued at current
market value; and short-term  instruments  maturing in more than sixty days when
purchased  that are held on the  sixtieth  day prior to  maturity  are valued at
amortized  cost (market value on the sixtieth day adjusted for  amortization  of
premium or accretion of discount),  which,  when combined with accrued interest,
approximates  market;  and  which,  in  either  case,  reflects  fair  value  as
determined by the Board of Trustees.  All other investments are valued at market
value or, where market  quotations are not readily  available,  at fair value as
determined  in good faith  according to procedures  established  by the Board of
Trustees.

DIVIDENDS AND TAXES

  Each Fund intends to declare  dividends from net  investment  income daily and
distribute  to its  shareholders  such  dividends  monthly  and to  declare  and
distribute  all net realized  long-term  capital  gains  annually.  Shareholders
receive Fund  distributions  in the form of  additional  shares of that class of
shares upon which the distribution is based or, at the shareholder's  option, in
cash.  Shareholders  of a Fund who have not opted to  receive  cash prior to the
payable date for any dividend from net investment  income or the record date for
any capital gains distribution will have the number of such shares determined on
the basis of the Fund's net asset  value per share  computed  at the end of that
day after adjustment for the distribution.  Net asset value is used in computing
the  number  of  shares  in  both   capital   gains  and   income   distribution
reinvestments.  There is a possibility that shareholders may lose the tax-exempt
status on accrued income on municipal  bonds if shares of the Funds are redeemed
before a dividend has been declared.

  As of April 1, 1995, in compliance with a recent ruling issued by the Internal
Revenue  Service  ("IRS"),  the FUND  treats its 12b-1 fees for tax  purposes as
operating expenses rather than capital charges.

  Account  statements  and/or checks as appropriate  will be mailed within seven
days after the Fund pays the distribution. Unless the FUND receives instructions
to the contrary  before the record or payable  date, as the case may be, it will
assume that a shareholder wishes to receive that distribution and future capital
gains and income distributions in shares.  Instructions continue in effect until
changed in writing.

  Each of the Funds  intends to qualify in the future as a regulated  investment
company under the Code.  Each Fund is a separate  taxable entity for purposes of
Code provisions applicable to regulated investment companies.  Each of the Funds
qualifies if, among other things,  it distributes to its  shareholders  at least
90% of its net investment  income for its fiscal year. Each Fund also intends to
make  timely  distributions,  if  necessary,  sufficient  in amount to avoid the
nondeductible  4% excise tax  imposed on a regulated  investment  company to the
extent that it fails to distribute, with respect to each calendar year, at least
98% of its  ordinary  income for such  calendar  year and 98% of its net capital
gains for the one-year  period ending on October 31 of such calendar  year.  Any
taxable  distribution (1) would be declared in October,  November or December to
shareholders  of  record  in such a month,  (2)  would be paid by the  following
January 31, and (3) would be  includable in the taxable  income of  shareholders
for the year in which such distribution was declared. If a Fund qualifies and if
it distributes  substantially  all of its net investment  income and net capital
gains,  if any, to  shareholders,  it will be relieved of any federal income tax
liability.

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

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

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

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

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

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

  The Funds may acquire options to "put" specified  securities to municipal bond
dealers or issuers from whom the securities  are purchased.  It is expected that
each Fund will be treated  for federal  income tax  purposes as the owner of the
municipal bonds acquired subject to the put. The interest on the municipal bonds
will be tax-exempt to the Funds,  and the purchase prices paid by the Funds must
be allocated  between such  securities and the puts based upon their  respective
fair market values. The IRS has not issued a published ruling on this matter and
could reach a different conclusion.

STATE INCOME TAXES

  The exemption of interest on municipal  bonds for federal  income tax purposes
does not necessarily result in exemption under the income, corporate or personal
property tax laws of any state or city.  Generally,  individual  shareholders of
the Funds  receive  tax-exempt  treatment  at the state level for  distributions
derived from  municipal  securities of their state of residency.  Texas does not
currently  impose  any  income  tax on  individuals  or  corporate  shareholders
(although  Texas does  impose a corporate  franchise  tax based,  in part,  on
reportable  federal  taxable  income on those  corporations  doing  business  in
Texas). Florida does not currently impose any individual income tax, although it
does impose a tax on corporate income.  Each Fund will report to shareholders on
a state by state  basis the  sources of its  exempt  interest  dividends.  For a
further  discussion of state tax treatment  relating to each Fund, see Exhibit A
to this prospectus.

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

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

FUND MANAGEMENT AND EXPENSES
BOARD OF TRUSTEES
Under Massachusetts law, the FUND's Board of Trustees has absolute and exclusive
control over the  management  and  disposition of all assets of the FUND and its
Funds.  Subject to the  authority of the Board of Trustees,  Keystone  serves as
investment  adviser to the FUND and its Funds and is responsible for the overall
management of the FUND's business and affairs.


INVESTMENT ADVISER

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

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

  Pursuant to its  Investment  Advisory and  Management  Agreement with the FUND
(the "Advisory Agreement"), Keystone provides investment advisory and management
services to the FUND and each Fund.

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

                                                                     Aggregate

0.25% of amounts over                                       $500,000,000

computed as of the close of business  each  business day and paid daily.  During
the year ended March 31, 1995, the Florida, Pennsylvania and Texas Funds paid or
accrued to Keystone  investment  management and administrative  services fees of
$515,205 (0.52% of the Fund's average annual net assets), $357,852 (0.54% of the
Fund's  average  annual net assets),  and $25,402  (0.55% of the Fund's  average
annual net assets), respectively.  During the year ended March 31, 1995, the New
York  Insured and  Massachusetts  Funds paid or accrued to  Keystone  investment
management  and  administrative  services  fees of $63,808  (0.55% of the Fund's
average  annual net assets) and $43,636  (0.55% of the Fund's average annual net
assets), respectively.

  The Advisory  Agreement  continues in effect from year to year only so long as
such  continuance  is  specifically  approved at least  annually by the Board of
Trustees or by vote of a majority  of the  outstanding  shares of each Fund.  In
either case, the terms of the Advisory Agreement and continuance thereof must be
approved  by the vote of a  majority  of  Independent  Trustees  in  person at a
meeting  called  for the  purpose  of  voting  on such  approval.  The  Advisory
Agreement may be terminated as to any Fund, without penalty, on 60 days' written
notice by the FUND or Keystone, or may be terminated as to a Fund by a vote of a
majority  of the shares of such Fund.  The  Advisory  Agreement  will  terminate
automatically upon its assignment.

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

FUND EXPENSES

  Each Fund will pay all of its expenses. In addition to the investment advisory
and management fees discussed  above,  the principal  expenses that each Fund is
expected to pay include,  but are not limited to, transfer,  dividend disbursing
and  shareholder  servicing  agent  costs  and  expenses;  custodian  costs  and
expenses;  its  pro  rata  portion  of  certain  Trustees'  fees,  fees  of  its
independent auditors,  fees of the FUND's legal counsel and legal counsel to the
FUND's  Board of  Trustees,  fees  payable  to  government  agencies,  including
registration  and  qualification  fees of the FUND,  the Funds and their  shares
under federal and state securities laws; and certain extraordinary  expenses. In
addition,  each  class  of  shares  of a Fund  will  pay  all  of  the  expenses
attributable  to it. Such expenses are currently  limited to  Distribution  Plan
expenses.  Each Fund also pays its brokerage  commissions,  interest charges and
taxes and certain extraordinary expenses.

  Until December 31, 1995, Keystone has voluntarily agreed to limit the expenses
of the FUND's Class A, B, and C shares to 0.75%,  1.50%, and 1.50%, of each such
class's  respective average daily net assets.  Thereafter,  a redetermination of
whether to continue these expense limitations and, if so, at what rates, will be
made.

  Keystone  will not be  required to make such  reimbursements  to the extent it
would result in a Fund's inability to qualify as a regulated  investment company
under the Code. In accordance  with certain  voluntary  expense  limitations  in
place  during the fiscal  year ended March 31,  1995,  Keystone  reimbursed  the
Florida,  Pennsylvania,  Texas,  Massachusetts  and New York  Insured  Funds (1)
$89,179,  $91,489, $35,517, $26,169 and $22,366,  respectively,  with respect to
each Fund's Class A shares; (2) $68,953, $81,415, $38,490, $64,511, and $85,602,
respectively,  with  respect to each  Fund's  Class B shares;  and (3)  $31,739,
$27,453,  $10,643,  $24,181,  and  $18,786,  respectively,  with respect to each
Fund's  Class C shares.  Keystone  does not intend to seek  repayment  for these
amounts.

  Each Fund may be subject to certain annual state expense limitations.

  During the fiscal year ended March 31,  1995,  the Florida,  Pennsylvania  and
Texas Funds paid or accrued to Keystone Investor Resource Center, Inc. ("KIRC"),
the FUND's  transfer and dividend  disbursing  agent,  $116,367,  $108,073,  and
$6,215,  respectively,  for shareholder  services.  During the fiscal year ended
March 31, 1995,  the  Massachusetts  and New York Insured  Funds paid or accrued
$25,831  and  $15,568 to KIRC for  shareholder  services.  During the year ended
March 31, 1995, the Florida,  Pennsylvania,  Texas,  Massachusetts  and New York
Insured Funds paid or accrued to KIRC and Keystone Investments $13,052, $20,909,
$13,870,  $17,498  and  $17,698,  respectively,  as  reimbursement  for  certain
accounting services. KIRC is a wholly-owned subsidiary of Keystone.

  For the fiscal year ended March 31,  1995,  the Class A, B and C shares of the
Florida,  Pennsylvania  and Texas  Funds  each  paid  0.75%,  1.50%  and  1.50%,
respectively, of each Fund's average net assets in expenses.

  For the fiscal year ended March 31,  1995,  the Class A, B and C shares of the
Massachusetts  Fund paid 0.46%,  1.24% and 1.23%,  respectively,  of average net
assets in expenses. For the fiscal year ended March 31, 1995, the Class A, B and
C shares of the New York Insured Fund paid 0.50%, 1.25% and 1.26%, respectively,
of average net assets in expenses.

  The foregoing expenses are net of expense  reimbursements  made by Keystone in
connection  with  voluntary  expense   limitations.   See  also  the  "Financial
Highlights" tables beginning on page 8 of this prospectus.

PORTFOLIO MANAGER

  Betsy A. Blacher,  a Keystone  Senior Vice  President and Group Head, has been
primarily  responsible  for the  management  of each of the  Funds  since  their
inception and is responsible for the day-to-day  management of the Florida Fund.
Ms Blacher has more than 16 years of investment experience.

  Daniel A. Rabasco, a Keystone Vice President and Portfolio  Manager,  has been

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 a Fund,
Keystone may follow a policy of  considering as a factor the number of shares of
the Fund  sold by such  broker-dealer.  In  addition,  broker-dealers  executing
portfolio  transactions  from  time to time may be  affiliated  with  the  FUND,
Keystone, the FUND's principal underwriter or their affiliates.

  A Fund may pay higher  commissions  to  broker-dealers  that provide  research
services.  Keystone  may use these  services  in  advising  a Fund as well as in
advising its other clients.

PORTFOLIO TURNOVER

  For the fiscal year ended March 31, 1994,  the turnover rates for the Florida,
Pennsylvania and Texas Funds were 113%, 37% and 56%, respectively.

  For the fiscal year ended March 31, 1995, the portfolio turnover rates for the
Florida, Pennsylvania and Texas Funds were 129%, 97% and 58%, respectively.

  For the fiscal year ended March 31, 1995, the portfolio turnover rates for the
Massachusetts and New York Insured Funds were 77% and 77%, respectively.

HOW TO BUY SHARES

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

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

  Orders for the  purchase of shares of a Fund will be  confirmed at an offering
price equal to the net asset value per share next  determined  after  receipt of
the order in proper form by the Principal Underwriter (generally as of the close
of the Exchange on that day) plus, in the case of Class A shares, the applicable
sales  charge.  Orders  received by dealers or other firms prior to the close of
the Exchange and received by the Principal Underwriter prior to the close of its
business day will be confirmed at the offering  price  effective as of the close
of the  Exchange on that day. The FUND  reserves the right to determine  the net
asset value more  frequently  than once a day if deemed  desirable.  Dealers and
other financial services firms are obligated to transmit orders promptly.

  Orders for shares of a Fund  received  other than as stated above will receive
the  offering  price  equal to the net asset  value per  share  next  determined
(generally the next business day's offering  price) plus, in the case of Class A
shares, the applicable sales charge.

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

  Shares become entitled to income distributions  declared on the first business
day following  receipt by KIRC of payment for the shares.  It is the  investor's
responsibility to see that his dealer promptly forwards payment to the Principal
Underwriter for shares being purchased through the dealer.

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

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

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

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

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

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

  Class A and B shares,  pursuant to their Distribution Plans,  currently pay an
annual service fee of 0.15% of the Fund's average daily net assets  attributable
to that  class,  and Class C shares  pay an annual  service  fee of 0.25% of the
Fund's  average  daily net assets  attributable  to Class C. In  addition to the
service fee, the Class B and Class C Distribution  Plans provide for the payment
of an annual  distribution  fee of up to 0.75% of the  average  daily net assets
attributable to their respective classes.

  Investors who would rather pay the entire cost of  distribution at the time of
investment,  rather than  spreading the cost over time,  might  consider Class A
shares.  Other investors might consider Class B or Class C shares, in which case
100% of the purchase price is invested  immediately,  depending on the amount of
the purchase and the length of investment.

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

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

  Class A shares are offered at net asset value plus an initial  sales charge as

 *Rounded to the nearest one-hundredth percent.

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

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

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

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

  The sales charge is paid to the Principal Underwriter,  which in turn normally
reallows  a portion  to your  broker-dealer.  In  addition,  your  broker-dealer
currently will be paid periodic service fees at an annual rate of up to 0.15% of
the average daily net asset value of Class A shares maintained by such recipient
outstanding on the books of the FUND for specified periods.

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

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

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

  In  addition,  since  January 1, 1995 and through June 30, 1995 and upon prior
notification  to the Principal  Underwriter,  Class A shares may be purchased at
net asset value by clients of registered representatives within six months after
the  redemption  of shares of any  registered  open-end  investment  company not
distributed or managed by Keystone or its affiliates,  where the amount invested
represents   redemption   proceeds  from  such  unrelated   registered  open-end
investment  company,  and the  shareholder  either  (1) paid a front  end  sales
charge,  or (2) was at some  time  subject  to,  but did  not  actually  pay,  a
contingent deferred sales charge with respect to the redemption proceeds.

CLASS A DISTRIBUTION PLAN

  Each Fund has adopted a  Distribution  Plan with respect to its Class A shares
(the "Class A Distribution  Plan") that provides for  expenditures  by the Fund,
currently  limited to 0.15%  annually  of the  average  daily net asset value of
Class A shares, in connection with the distribution of Class A shares.  Payments
under  each  Class A  Distribution  Plan  are  currently  made to the  Principal
Underwriter  (which may  reallow  all or part to  others,  such as  dealers)  as
service  fees at an annual  rate of up to 0.15% of the  average  daily net asset
value of Class A shares maintained by the recipients outstanding on the books of
the Fund for specified periods.

CLASS B SHARES

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

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

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

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

No deferred sales charge is imposed on amounts redeemed thereafter.

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

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

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

CLASS B DISTRIBUTION PLANS

  Each Fund has adopted  Distribution  Plans with  respect to its Class B shares
(the "Class B Distribution  Plans") that provide for expenditures by the Fund at
an annual  rate of up to 1.00% of the  average  daily net asset value of Class B
shares (currently limited to 0.90%) to pay expenses of the distribution of Class
B shares.  Payments under the Class B  Distribution  Plans are currently made to
the  Principal  Underwriter  (which may reallow  all or part to others,  such as
dealers)  (1) as  commissions  for  Class B shares  sold and (2) as  shareholder
service fees. Amounts paid or accrued to the Principal Underwriter under (1) and
(2) in the aggregate may not exceed the annual limitation referred to above.

  The Principal Underwriter generally reallows to brokers or others a commission
equal to 4.00% of the  price  paid for each  Class B share  sold  plus the first
year's  service fee in advance in the amount of 0.15% of the price paid for each
Class B share sold.  Beginning  approximately  12 months after the purchase of a
Class B share,  the broker or other party will receive service fees at an annual
rate of  0.15% of the  average  daily  net  asset  value  of such  Class B share
maintained by the recipient  outstanding  on the books of the Fund for specified
periods. See "Distribution Plans" below.

  With respect to the FUND's Class B shares only, for the period June 1, 1995 to
August 31, 1995, the Principal  Underwriter will reallow an increased commission
equal  to  4.85%  of the  price  paid  for  each  Class  B share  sold to  those
broker/dealers or others who allow their individual  selling  representatives to
participate in the additional 0.85% commission.

CLASS C SHARES

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

CLASS C DISTRIBUTION PLAN

  Each Fund has adopted a  Distribution  Plan with respect to its Class C shares
(the "Class C Distribution  Plan") that provides for  expenditures  at an annual
rate of up to 1.00%  of the  average  daily  net  asset  value of Class C shares
(currently  limited to 0.90%) to pay  expenses  of the  distribution  of Class C
shares.  Payments under the Class C Distribution  Plan are currently made to the
Principal Underwriter (which may reallow all or part to others, such as dealers)
(1) as commissions for Class C shares sold and (2) as shareholder  service fees.
Amounts paid or accrued to the  Principal  Underwriter  under (1) and (2) in the
aggregate may not exceed the annual limitation  referred to above. The Principal
Underwriter  generally  reallows to brokers or others a commission in the amount
of 0.75% of the price paid for each Class C share  sold,  plus the first  year's
service fee in advance in the amount of 0.25% of the price paid for each Class C
share sold,  and,  beginning  approximately  fifteen  months after  purchase,  a
commission  at  an  annual  rate  of  0.75%   (subject  to  NASD  rules  --  see
"Distribution   Plans")   plus  service  fees  at  the  annual  rate  of  0.25%,
respectively,  of the  average  daily  net  asset  value  of each  Class C share
maintained by the recipients  outstanding on the books of the Fund for specified
periods. See "Distribution Plans" below.

CONTINGENT DEFERRED SALES CHARGE AND WAIVER OF SALES CHARGES

  Any  contingent  deferred sales charge imposed upon the redemption of Class A,
Class B or Class C shares  is a  percentage  of the  lesser of (1) the net asset
value of the shares  redeemed  or (2) the net asset value at time of purchase of
such  shares.  No  contingent  deferred  sales  charge is imposed  when  amounts
redeemed are derived from (1) increases in the value of an account above the net
cost of such  shares due to  increases  in the net asset value per share of such
shares; (2) certain shares with respect to which a Fund did not pay a commission
on issuance,  including shares acquired through  reinvestment of dividend income
and capital gains  distributions;  (3) certain Class A shares held for more than
one year or two years, as the case may be, from the date of purchase;  (4) Class
B shares held during more than four  consecutive  calendar years or more than 72
months  after the month of  purchase,  as the case may be; or (5) Class C shares
held for more than one year from date of purchase.  Upon request for redemption,
shares not  subject to the  contingent  deferred  sales  charge will be redeemed
first. Thereafter, shares held the longest will be the first to be redeemed.

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

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

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


ARRANGEMENTS WITH BROKER-DEALERS AND OTHERS

  From  time  to  time,  the  Principal   Underwriter  may  provide  promotional
incentives,  including  reallowance of up to the entire sales charge, to certain
dealers  whose  representatives  have sold or are  expected to sell  significant
amounts  of a  Fund.  In  addition,  from  time to  time,  dealers  may  receive
additional  cash  payments.   The  Principal  Underwriter  may  provide  written
information to dealers with whom it has dealer  agreements that relates to sales
incentive campaigns conducted by such dealers for their  representatives as well
as financial  assistance in connection with pre-approved  seminars,  conferences
and advertising.  No such programs or additional compensation will be offered to
the extent they are  prohibited by the laws of any state or any  self-regulatory
agency such as the National  Association of Securities  Dealers,  Inc. ("NASD").
Dealers  to whom  substantially  the  entire  sales  charge on Class A shares is
reallowed  may be deemed to be  underwriters  as that term is defined  under the
Securities Act of 1933.

  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 a transaction fee (up to the level of
payments allowed to dealers for the sale of shares, as described above) to banks
and other financial  services firms that facilitate  transactions in shares of a
Fund for their clients. The Glass-Steagall Act currently limits the ability of a
depository  institution  (such  as a  commercial  bank  or a  savings  and  loan
association) to become an underwriter or distributor of securities. In the event
the  Glass-Steagall  Act is  deemed to  prohibit  depository  institutions  from
accepting  payments under the  arrangement  described  above, or should Congress
relax current  restrictions  on depository  institutions,  the Board of Trustees
will consider what action, if any, is appropriate.

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

DISTRIBUTION PLANS

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

  The  NASD  currently  limits  the  amount  that a Fund  may  pay  annually  in
distribution costs for the sale of its shares and shareholder  service fees. The
rule limits annual  expenditures to 1% of the aggregate  average daily net asset
value of its shares, of which 0.75% may be used to pay such  distribution  costs
and 0.25% may be used to pay shareholder  service fees. The NASD also limits the
aggregate  amount  that a Fund may pay for such  distribution  costs to 6.25% of
gross  share  sales  since the  inception  of a 12b-1  Distribution  Plan,  plus
interest at the prime rate plus 1% on such amounts (less any contingent deferred
sales  charges paid by  shareholders  to the  Principal  Underwriter)  remaining
unpaid from time to time.

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

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

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

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

  For the  Florida,  Pennsylvania,  Texas,  Massachusetts  and New York  Insured
Funds,  unreimbursed  Class B Distribution  Plan expenses at March 31, 1995 were
$3,196,058  (6.26%  of Class B net  assets),  $1,923,455  (6.27%  of Class B net
assets),  $145,495 (6.73% of Class B net assets), $384,672 (6.24% of Class B net
assets), and $728,940 (6.12% of Class B net assets), respectively.

  For  the  year  ended  March  31,  1995,  the  Florida,  Pennsylvania,  Texas,
Massachusetts  and New York Insured  Funds paid the  Principal  Underwriter  (1)
$66,246,  $44,697,  $2,847, $1,829, and $3,025,  respectively,  pursuant to each
Fund's Class A Distribution Plan; (2) $345,221,  $244,404, $18,613, $40,387, and
$70,227,  respectively,  pursuant to each Fund's Class B Distribution  Plan; and
(3) $140,405, $81,781, $5,377, $15,014, and $15,895,  respectively,  pursuant to
each Fund's Class C Distribution Plan.

  Dealers or others may receive  different  levels of compensation  depending on
which class of shares they sell.  Payments  pursuant to a Distribution  Plan are
included in the operating expenses of the class.

HOW TO REDEEM SHARES

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

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

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

  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 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 redemption proceeds has been delayed, the
check will be mailed or the proceeds  wired promptly after good payment has been
collected.

  The FUND  computes  the amount due you at the close of the Exchange at the end
of the day on which it has received all proper  documentation  from you. Payment
of the amount due on redemption  less any applicable  contingent  deferred sales
charge (as described above) will be made within seven days thereafter  except as
discussed herein.

  You  may  also  redeem  your  shares  through  broker-dealers.  The  Principal
Underwriter,  acting as agent for the FUND,  stands ready to repurchase a Fund's
shares upon orders from dealers at the redemption value described above computed
on the day the  Principal  Underwriter  receives  the  order.  If the  Principal
Underwriter  has  received  proper  documentation,  it will  pay the  redemption
proceeds to the  broker-dealer  placing the order within seven days  thereafter.
The Principal Underwriter charges no fees for this service.
However, your broker-dealer may do so.

  For your protection,  SIGNATURES ON CERTIFICATES, STOCK POWERS AND ALL WRITTEN
ORDERS OR  AUTHORIZATIONS  MUST BE GUARANTEED BY A U.S. STOCK EXCHANGE MEMBER, A
U.S.  COMMERCIAL  BANK OR TRUST COMPANY OR OTHER  PERSONS  ELIGIBLE TO GUARANTEE
SIGNATURES  UNDER THE SECURITIES ACT OF 1934 AND KIRC'S  POLICIES.  The FUND and
KIRC may waive this requirement,  but may also require  additional  documents in
certain cases.  Currently,  the requirement  for a signature  guarantee has been
waived on redemptions of $50,000 or less where the account address of record has
been the same for a minimum  period of 30 days.  The FUND and KIRC  reserve  the
right to withdraw this waiver at any time.

  If the FUND receives a redemption  order,  but you have not clearly  indicated
the amount of money or number of shares of the Fund  involved,  the FUND  cannot
execute the order. In such cases, the FUND will request the missing  information
from you and process the order on the day such information is received.

TELEPHONE

  Under ordinary  circumstances,  you may redeem up to $50,000 from your account
by telephone by calling toll free 1-800-343-2898.

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

  If the redemption proceeds are less than $2,500, they will be mailed by check.
If they are $2,500 or more,  they will be  mailed,  wired or sent by EFT to your
previously  designated bank account as you direct. If you do not specify how you
wish your redemption proceeds to be sent, they will be mailed by check.

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

SMALL ACCOUNTS

  Due to the high cost of  maintaining  small  accounts,  the FUND  reserves the
right to redeem your account if its value has fallen below  $1,000,  the current
minimum  investment  level, as a result of your redemptions (but not as a result
of market  action).  You will be  notified  in  writing  and  allowed 60 days to
increase the value of your account to the minimum investment level.

REDEMPTIONS IN KIND

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

GENERAL

  The FUND  reserves the right at any time to  terminate,  suspend or change the
terms of any redemption  method described in this prospectus,  except redemption
by mail,  and to impose or change fees including fees for services in connection
with exchanges.

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

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

SHAREHOLDER SERVICES

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

KEYSTONE AUTOMATED RESPONSE LINE

  KARL offers you specific fund account  information and price, total return and
yield  quotations as well as the ability to do account  transactions,  including
investments, exchanges and redemptions. You may access KARL by dialing toll free
1-800-346-3858 on any touch-tone telephone, 24 hours a day, seven days a week.

EXCHANGES

  If you have obtained the appropriate prospectus,  you may exchange shares of a
Fund for shares of certain  other  Keystone  America  Funds and Keystone  Liquid
Trust ("KLT") as follows:

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

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

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

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

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

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

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

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

  You may exchange shares by calling toll free
1-800-343-2898,  by writing KIRC or by calling KARL.  Shares  purchased by check
are  eligible  for  exchange  after  15 days.  There  is a  $10.00  fee for each
exchange.  If an exchange  order is made by an individual  investor  using KARL,
there is no fee. The FUND reserves the right, after providing  shareholders with
any required  notice to  shareholders,  to terminate  this exchange  offer or to
change its terms, including the right to change the fee for any exchange.

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

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

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

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

KEYSTONE AMERICA MONEY LINE

  Keystone  America  Money Line  eliminates  the delay of mailing a check or the
expense of wiring  funds.  You must  request  the  service on your  application.
Keystone  America  Money Line allows you to  authorize  electronic  transfers of
money to  purchase  a Fund's  shares in any  amount  and to redeem up to $50,000
worth of a Fund's  shares.  You can use  Keystone  America  Money  Line  like an
"electronic  check" to move money  between your bank account and your account in
the FUND with one  telephone  call.  You must allow two business  days after the
call for the transfer to take place. For money recently invested, you must allow
normal check clearing time before redemption proceeds are sent to your bank.

  You may also arrange for systematic  monthly or quarterly  investments in your
Keystone America account.  Once proper authorization is given, your bank account
will be  debited  to  purchase  shares  in the Fund  specified  in your  account
application.  You will receive  confirmation from the Principal  Underwriter for
every transaction.

  To change the amount of or  terminate a Keystone  America  Money Line  service
(which could take up to 30 days), you must write to KIRC, P.O. Box 2121, Boston,
Massachusetts 02106-2121, and include your account number.

AUTOMATIC WITHDRAWAL PLAN

  Under an Automatic  Withdrawal Plan, if your account for a Fund's shares has a
value of at least  $10,000,  you may arrange for  regular  monthly or  quarterly
fixed withdrawal payments. Each payment must be at least $100 and may be as much
as 1.5% per month or 4.5% per  quarter of the total net asset  value of the Fund
shares in your account when the Automatic  Withdrawal Plan is opened.  Excessive
withdrawals  may decrease or deplete the value of your  account.  Because of the
effect of the  applicable  sales  charge,  a Class A  investor  should  not make
continuous  purchases  of a Fund's  shares while  participating  in an Automatic
Withdrawal Program.

DOLLAR COST AVERAGING

  Through  dollar cost averaging you can invest a fixed dollar amount each month
or each quarter in any Keystone  America Fund. This results in more shares being
purchased  when the selected  fund's net asset value is relatively low and fewer
shares being purchased when the fund's net asset value is relatively high, which
may cause a lower  average  cost per  share  than a less  systematic  investment
approach.

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

TWO DIMENSIONAL INVESTING

  You may elect to have income and capital gains distributions from any class of
Keystone America Fund shares you may own automatically  invested to purchase the
same class of shares of any other  Keystone  America  Fund.  You may select this
service on the application and indicate the Keystone  America Fund(s) into which
distributions  are to be  invested.  The  value  of  shares  purchased  will  be
ineligible for Rights of  Accumulation  and Letters of Intent.  Two  dimensional
investing  is available  only in states where shares of the Fund being  acquired
may legally be sold.

OTHER SERVICES

  Under  certain  circumstances,  you may,  within 30 days  after a  redemption,
reinstate  your account in the same class of shares that you redeemed at current
net asset value.

PERFORMANCE DATA

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

  Current yield  quotations  represent  the yield on an investment  for a stated
30-day period computed by dividing net investment income earned per share during
the base period by the maximum  offering  price per share on the last day of the
base period.  Such yield will include  income from sources other than  municipal
obligations, if any.

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

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

  The FUND may also include comparative  performance  information for each class
of shares when  advertising  or marketing the FUND's  shares,  such as data from
Lipper Analytical Services, Inc., Morningstar, Inc., S&P, Ibbotson Associates
or other industry publications.

FUND SHARES

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


  Shareholders  of a Fund are entitled to one vote for each full share owned and
fractional  votes for  fractional  shares on all  matters  subject to Fund vote.
Shares of a Fund vote together except when required by law to vote separately by
class.  The FUND does not have  annual  meetings.  The FUND  will  have  special
meetings,  from time to time,  as required  under its  Declaration  of Trust and
under the 1940 Act. As provided in the FUND's Declaration of Trust, shareholders
have the right to remove  Trustees by an  affirmative  vote of two-thirds of the
outstanding  shares. A special meeting of the shareholders will be held when 10%
of the  outstanding  shares  request a meeting  for the  purpose  of  removing a
Trustee.  As prescribed by Section  16(c) of the 1940 Act,  shareholders  may be
eligible for shareholder communication assistance in connection with the special
meeting.


  Under  Massachusetts  law, it is possible that a FUND  shareholder may be held
personally liable for the FUND's  obligations.  The FUND's  Declaration of Trust
provides,  however,  that  shareholders  shall not be  subject  to any  personal
liability  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 FUNDS

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

OBLIGATIONS OF UNITED STATES BRANCHES OF FOREIGN BANKS

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

MASTER DEMAND NOTES

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

REPURCHASE AGREEMENTS

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

REVERSE REPURCHASE AGREEMENTS

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

"WHEN ISSUED" SECURITIES

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

LOANS OF SECURITIES TO BROKER-DEALERS

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

DERIVATIVES

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

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

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

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

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

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

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

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

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

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

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

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

OPTIONS TRANSACTIONS

  WRITING COVERED OPTIONS.  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,  a Fund becomes  obligated  during the
term of the  option to  purchase  the  securities  underlying  the option at the
exercise  price if the option is  exercised.  The Fund also may write  straddles
(combinations of covered puts and calls on the same underlying security).

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

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

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

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

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

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

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

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

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

FUTURES TRANSACTIONS

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

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

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

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

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

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

FOREIGN CURRENCY TRANSACTIONS

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

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

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

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

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

                        KEYSTONE FLORIDA TAX FREE FUND
DESCRIPTION OF STATE AND LOCAL TAX TREATMENT
  Florida  does not  presently  impose an  income  tax on  individuals  and thus
individual  shareholders  of the Florida Fund will not be subject to any Florida
state income tax on distributions  received from the Florida Fund. Shares of the
Florida Fund may, however,  be subject to Florida  intangible  personal property
tax  imposed on  certain  property  held on  January 1 of each  year.  Corporate
shareholders,  depending on the domicile of the  corporation,  may be subject to
Florida  corporate  income taxes  depending on the portion of the Florida Fund's
income that is allocable to Florida under applicable Florida law.

  According  to a  technical  assistance  advisement  from the State of Florida,
Department  of Revenue,  shares of the Florida Fund owned by a Florida  resident
will  be  exempt  from  the  intangible  personal  property  tax so  long as its
portfolio  assets consist 100% of securities that are exempt from the intangible
personal property tax,  including Florida municipal bonds and/or municipal bonds
issued by the U.S.  Government or the  governments  of Puerto Rico or Guam.  The
technical assistance advisement will not be binding on the Department of Revenue
for any  shareholder  of the Fund;  however,  such  advisements  are  considered
helpful in understanding the Department's position on any particular tax issue.

SPECIAL FACTORS AFFECTING THE FLORIDA FUND

  Under  current  law,  the State of Florida is  required to maintain a balanced
budget so that current expenses are met from current revenues.  Florida does not
currently  impose a tax on personal  income.  It does impose a tax on  corporate
income derived from activities within the State. In addition, Florida imposes an
ad valorem tax on certain  intangible  property (see above) as well as sales and
use taxes. These taxes are the principal source of funds to meet State expenses,
including  repayment of, and interest on,  obligations backed solely by the full
faith and credit of the State.

  Florida's  Constitution permits the issuance of state or municipal obligations
pledging the full faith and credit of the State,  with a concurring  vote by the
respective electors,  to finance or refinance capital projects authorized by the
Legislature.  The State  Constitution  also provides that the Legislature  shall
appropriate  monies  sufficient to pay debt service on state bonds  pledging the
full faith and credit of the State as they become due.  All State tax  revenues,
other than trust funds dedicated by the State  Constitution  for other purposes,
are available for such an appropriation, if required.

  On the other hand,  municipalities  and other  political  subdivisions  of the
State  principally  rely on a combination  of ad valorem taxes on real property,
user  fees and  occupational  license  fees to meet  their  day-to-day  expenses
including  the  repayment  of principal  of, and interest on, their  obligations
backed by their full faith and credit.  (Revenue bonds, of course, are dependent
on the revenue generated by a specific facility or enterprise.)

  Florida  has  experienced  substantial  population  increases  as a result  of
migration to Florida  from other areas of the U.S.  and from foreign  countries.
This  population  growth is expected to  continue,  and it is  anticipated  that
corresponding  increases in State  revenues  will be  necessary  during the next
decade to meet  increased  burdens on the  various  public  and social  services
provided by the State.

  Florida's  ability to meet increasing  expenses will be dependent in part upon
the State's  continued  ability to foster business and economic growth.  Florida
has experienced  significant  increases in the  technology-based and other light
industries and in the service  sector.  This growth has  diversified the State's
overall  economy,  which at one time was  dominated  by the citrus  and  tourism
industries.  The State's  economic  and  business  growth  could be  restricted,
however, by the natural limitations on Florida's water supplies.

                     KEYSTONE MASSACHUSETTS TAX FREE FUND
DESCRIPTION OF STATE AND LOCAL TAX TREATMENT
  Under Massachusetts law, individual shareholders of the Massachusetts Fund who
are  subject  to  Massachusetts  personal  income  tax  will not be  subject  to
Massachusetts personal income tax on dividends paid by the Massachusetts Fund to
the extent such  dividends  are exempt from  federal  income tax and are derived
from interest payments on Massachusetts municipal securities.  Long term capital
gains  distributions  are taxable as long term capital  gains,  except that such
distributions  derived from the sale of certain  Massachusetts  obligations  are
exempt from Massachusetts personal income tax. These obligations,  which are few
in number,  are those issued pursuant to legislation that  specifically  exempts
gain on their  sale from  Massachusetts  income  taxation.  Dividends  and other
distributions are not exempt from Massachusetts corporate excise tax.

SPECIAL FACTORS AFFECTING THE MASSACHUSETTS FUND

  During the past decade, the Massachusetts economy shifted from labor intensive
manufacturing to services,  especially in the medical and  biotechnology  areas.
Although The Commonwealth experienced an economic slowdown during the recession,
especially in high  technology,  real estate,  banking,  and defense,  there are
signs of improvement. While roughly 9.5% of the employment base was lost between
1989 and 1991, employment rose 0.4% between November,  1992 and November,  1993.
Although job losses continued in high tech manufacturing and finance during 1992
and 1993,  strong gains were registered in services,  construction and high tech
non-manufacturing.  The December,  1993  unemployment  rate was 6.3% compared to
6.4% for the nation.  In addition,  per capita  personal income averaged 118% of
the national average in 1992.

  Although The  Commonwealth  experienced  quite a slowdown during the recession
with  spending  exceeding  revenues,  beginning  in 1991  the  Commonwealth  has
experienced a turn-around  in its finances  with  revenues  exceeding  spending.
Budgeted  expenditures for fiscal 1989, 1990 and 1991 were approximately $12.643
billion,  $13.260  billion  and $13.659  billion,  respectively  while  budgeted
revenues and other sources for those years were  approximately  $11.970 billion,
$12.008  billion and $13.634  billion,  respectively.  By  comparison,  budgeted
revenues and other sources  increased by approximately  0.7% from fiscal 1991 to
fiscal 1992, while tax revenues increased by 5.4% for the same period.  Budgeted
expenditures   in  fiscal  1992  were  1.7%  lower  than  fiscal  1991  budgeted
expenditures.  Furthermore,  total  revenues  and other  sources for fiscal 1993
increased  approximately  6.9% from fiscal 1992, while tax revenues increased by
4.7% for the same period.  Budgeted  expenditures  and other uses in fiscal 1993
were  approximately  9.6% higher than fiscal 1992  expenditures  and other uses.
Fiscal 1993 ended with  positive fund  balances of $562.5  million,  including a
combined balance of $452.1 million in the stabilization and undesignated general
funds.  By  comparison,  The  Commonwealth  ended the 1989 fiscal year with fund
balances in deficit by $319.3 million.

  The fiscal 1994  budget,  as signed into law by the Governor on July 19, 1993,
provides for expenditures of approximately  $15.500 billion, an increase of 5.5%
over fiscal 1993 levels.  Budgeted  revenues for fiscal 1994 are estimated to be
approximately   $15.483   billion,   which  is  5.3%  higher  than  fiscal  1993
expenditures.  This amount  includes  estimated  tax  revenues of  approximately
$10.560 billion,  which is 6.3% higher than fiscal 1993 tax revenues. For fiscal
1994, a combined balance of $541.4 million is expected in the  stabilization and
undesignated  general  funds.  The fiscal  1994  budget is based  upon  numerous
spending and revenue estimates, the achievement of which cannot be assured.

  In June 1993, new comprehensive  education reform legislation was enacted.  It
is expected that this  legislation will require annual increases in expenditures
for education  purposes  above fiscal 1993 base spending of $1.289  billion,  of
approximately  $175 million in fiscal 1994, $141 million in fiscal 1995 and $662
million  in fiscal  1996.  The  fiscal  1994  budget  includes  $175  million in
appropriations to satisfy this legislation.

  In November 1980, voters in The Commonwealth  approved a state-wide limitation
initiative  petition,  commonly  known as  Proposition  2 1/2, to constrain  the
levels of property  taxation and to limit the charges and fees imposed on cities
and towns by certain governmental  entities.  Many communities have responded to
the limitations of Proposition 2 1/2 through statutorily permitted overrides and
exclusions.  Override activity peaked in fiscal 1991 when 100 of 182 communities
had successful votes,  adding $58.5 million to their levy limits.  During fiscal
years 1992 and 1993,  123  communities  had  successful  votes  totalling  $47.4
million.  Although  Proposition 2 1/2 will continue to constrain  local property
tax revenues, significant capacity exists for overrides in nearly all cities and
towns.

  An  expanded   discussion   is  contained  in  the   statement  of  additional
information.

                   KEYSTONE NEW YORK INSURED TAX FREE FUND
DESCRIPTION OF STATE AND LOCAL TAX TREATMENT
  Individual  shareholders  of the New York  Insured Fund who are subject to New
York State and New York City personal income tax will not be subject to New York
State or City personal income tax on dividends paid by the New York Insured Fund
to the extent that they are derived from interest on obligations of the State of
New York and its political  subdivisions that is exempt from federal income tax.
In addition,  dividends  derived  from  interest on debt  obligations  issued by
certain other governmental entities (for example, U.S.
territories) will be similarly exempt.

  For New York State and City personal  income tax  purposes,  long term capital
gain  distributions  are taxable as long term capital  gains  regardless  of the
length of time  shareholders  have owned their shares.  Short term capital gains
and any other taxable income are taxable as ordinary income.

  To the extent that investors are obligated to pay state or local taxes outside
of the State of New York,  dividends  earned  by an  investment  in the New York
Insured Fund may represent taxable income.  Distributions from investment income
and capital gains, including  exempt-interest  dividends,  may be subject to New
York State franchise taxes and to the New York City General  Corporation Tax, if
received by a corporation subject to those taxes, to state taxes in states other
than New York and to local taxes in cities other than New York City.

SPECIAL FACTORS AFFECTING THE NEW YORK FUND

  The New York economy was severely impacted by the recession,  but it has begun
to show signs of recovery.  The  recession has been more severe in New York than
in  other  parts  of the  nation,  owing to a  significant  retrenchment  in the
financial services industry, cutbacks in defense spending, and an overbuilt real
estate  market.   More  than  564,000  jobs  were  lost  during  the  recession,
representing 7% of the pre-recession base. During 1993,  employment continued to
decline but at  diminishing  rates (a 0.3% decline  during  1993),  indicating a
stabilizing  economy.  A modest job growth of approximately  0.8% is anticipated
for 1994. It is  anticipated  that New York's  service and trade sectors will be
the  major  contributors  to this  growth,  while  the  manufacturing  sector is
expected to continue to contract.  The State's economy is significantly affected
by New York City's economy by virtue of New York City's  dominance in population
and  economic  activity.  New York City  accounts for  approximately  41% of the
State's population and personal income.

  The revised 1993-1994 State Financial Plan is based on an economic  projection
that New  York  will  perform  more  poorly  than the  nation  as a whole.  Many
uncertainties  exist in  forecasts of the State's  economy,  which could have an
adverse  effect  on the  State,  and there  can be no  assurance  that the State
economy  will not  experience  worse-than-predicted  results in the 1994  fiscal
year, with corresponding material and adverse effects on the State's projections
of receipts and disbursements.

  For fiscal 1993, State financial operations produced a $671 million surplus on
a general fund budget of nearly $31 billion. This surplus followed four years of
operating deficits. On a GAAP basis, the accumulated general fund deficit peaked
in 1991 at $6.2 billion and then decreased to $2.6 billion for fiscal 1993. Debt
reform is the principal  cause for this  improvement.  Short-term  borrowing is
only $850 million for the current  fiscal year,  the lowest level since 1969. To
reduce  borrowing  costs and improve market access,  the Governor is proposing a
constitutional  amendment to limit issuance of appropriation bonds and to create
tax-backed debt.

  The State's updated  financial plan estimates that fiscal 1994 will achieve an
ending cash balance of approximately $299 million.  This larger than anticipated
surplus is a result of a  stabilizing  economy,  improving tax  collections  and
slowing  expenditure  growth. The 1993 and 1994 budgets were enacted in a timely
manner and were based on  realistic  economic  forecasts,  conservative  revenue
assumptions  and some spending  restraint.  The Governor's  proposed  budget for
fiscal  1995  provides  for general  fund  spending  growth of 4.3%,  use of the
current  year  surplus,  modest  tax  cuts and a small  level  of  non-recurring
measures. The fiscal 1995 financial plan is based on a forecast of slow economic
growth and projects increases in the personal income tax and user taxes and fees
of 5.3% and 4.1%, respectively.

  Significant  litigation exists at the State level of government.  A suit filed
by a taxpayer activist  challenges the  constitutionality  of the transportation
financing  plan.  Also, in November 1993, the Court of Appeals  affirmed a lower
court's  decision,  declaring that a change in the actuarial  funding method for
determining  contributions  by the  State  and its  local  governments  to their
respective retirement systems was unconstitutional. The State may also be liable
for  significant  payments  related to a U.S.  Supreme Court decision  involving
abandoned property.

  An  expanded   discussion   is  contained  in  the   statement  of  additional
information.

                     KEYSTONE PENNSYLVANIA TAX FREE FUND
DESCRIPTION OF STATE AND LOCAL TAX TREATMENT
  Individual  shareholders  of the  Pennsylvania  Fund  who are  subject  to the
Pennsylvania  personal income tax, as either  residents or  non-residents of the
Commonwealth  of  Pennsylvania,  will not be  subject to  Pennsylvania  personal
income tax on distributions  of interest made by the Pennsylvania  Fund that are
attributable to (1) obligations issued by the Commonwealth of Pennsylvania,  any
public  authority,  commission,  board or agency created by the  Commonwealth of
Pennsylvania,  any political  subdivision of the Commonwealth of Pennsylvania or
any public authority  created by any such political  subdivision  (collectively,
"Pennsylvania  Obligations");  and (2)  obligations  of the  United  States  and
certain qualifying agencies,  instrumentalities,  territories and possessions of
the United  States,  the  interest  from which are  statutorily  free from state
taxation in the Commonwealth of Pennsylvania  under the laws of the Commonwealth
or the U.S. (collectively,  "U.S. Obligations").  Distributions  attributable to
most other  sources will not be exempt from  Pennsylvania  personal  income tax.
Distributions  of  gains  attributable  to  Pennsylvania  Obligations  and  U.S.
Obligations   (collectively   "Exempt  Obligations")  will  be  subject  to  the
Pennsylvania personal income tax.

  Shares of the Pennsylvania  Fund that are held by individual  shareholders who
are Pennsylvania  residents subject to the Pennsylvania county personal property
tax will be exempt  from such tax to the  extent  that the  Pennsylvania  Fund's
portfolio  consists  of  Exempt  Obligations  on  the  annual  assessment  date.
Nonresidents  of  the  Commonwealth  of  Pennsylvania  are  not  subject  to the
Pennsylvania  county  personal  property  tax.  Corporations  are not subject to
Pennsylvania  personal property taxes. For shareholders who are residents of the
City of Philadelphia,  distributions of interest derived from Exempt Obligations
are not taxable for  purposes of the  Philadelphia  School  District  investment
income tax provided  that the  Pennsylvania  Fund reports to its  investors  the
percentage of Exempt  Obligations held by it for the year. The Pennsylvania Fund
will report such percentage to its shareholders.

  Distributions of interest,  but not gains,  realized on Exempt Obligations are
not  subject to the  Pennsylvania  corporate  net income tax.  The  Pennsylvania
Department  of Revenue also takes the position  that shares of funds  similar to
the Pennsylvania  Fund are not considered exempt assets of a corporation for the
purpose of  determining  its capital stock value  subject to the  Commonwealth's
capital stock and franchise taxes.

SPECIAL FACTORS AFFECTING THE PENNSYLVANIA FUND

  Historically,  Pennsylvania is among the leading states in  manufacturing  and
mining,  and its steel and coal  industries  have been of  national  importance.
However,  due in  part  to  the  decline  in  the  steel  and  coal  industries,
Pennsylvania's  economy has become more  diversified,  with major new sources of
growth in the service and trade sectors. The Commonwealth's unemployment rate is
below the  national  average,  and its per capita  income is slightly  above the
national  average.  The  Commonwealth's  General  Fund,  through which taxes are
received and debt service is made, had unappropriated  balance surpluses for the
years ended June 30, 1992 and June 30, 1993.

  The  Pennsylvania  Fund's yield and share price  stability are tied in part to
conditions  within  the  Commonwealth.  Changes  in  economic  conditions  in or
governmental policies of the Commonwealth could have a significant impact on the
performance  of  Pennsylvania  Obligations  held by the  Pennsylvania  Fund. For
example, the Commonwealth's  continued  dependence on manufacturing,  mining and
steel has made the Commonwealth  vulnerable to cyclical  industry  fluctuations,
foreign  imports  and  environmental  concerns.  Growth in the service and trade
sectors, however, has helped diversify the Commonwealth's economy and reduce its
unemployment  rate  below  the  national  average.  Changes  in  local  economic
conditions or local  governmental  policies within the  Commonwealth,  which can
vary  substantially  by  region,  could  also have a  significant  impact on the
performance of municipal  obligations held by the  Pennsylvania  Fund. Also, the
Pennsylvania  Fund will invest in obligations that are secured by obligors other
than  the  Commonwealth  or  its  political  subdivisions  (such  as  hospitals,
universities,  corporate obligors and corporate credit and liquidity  providers)
and  obligations  limited to specific  revenue  pledges (such as sewer authority
bonds).  The  creditworthiness  of  these  obligors  may  be  wholly  or  partly
independent  of the  creditworthiness  of  the  Commonwealth  or  its  municipal
authorities.  The Trustees of the Pennsylvania Fund have the power,  however, to
eliminate unsafe investments.

  An  expanded   discussion   is  contained  in  the   statement  of  additional
information.

                         KEYSTONE TEXAS TAX FREE FUND

DESCRIPTION OF STATE AND LOCAL TAX TREATMENT

  Texas does not presently  impose an income tax on individuals or corporations.
Consequently,  neither individual nor corporate  shareholders will be subject to
any Texas state income tax on distributions  received from the Texas Fund. Texas
does, however, impose a corporate franchise tax on corporations that do business
in Texas or are chartered or  authorized to do business in Texas.  The corporate
franchise tax imposed on those corporations is an amount equal to the greater of
(1) 1/4 of 1% of the corporation's  "taxable capital" apportioned to Texas, less
certain  deductions,  or (2) 4.5% of the corporation's  "taxable earned surplus"
apportioned to Texas, less certain deductions and loss carryforwards. The amount
of "taxable earned surplus" is based generally on the corporation's  "reportable
federal  taxable income" as computed under the Code.  Exempt interest  dividends
distributed  by the Texas  Fund are  expected  to be  excluded  from  reportable
federal  taxable  income by federal law and likewise  excluded  from the taxable
earned  surplus  component upon which the Texas  corporate  franchise tax may be
imposed.  Corporations  that do business in Texas or are chartered or authorized
to do business in Texas should consult their own tax advisors regarding the full
impact of the Texas franchise tax.

  Under  present  law,  the Texas Fund will not be  subject  to Texas  corporate
franchise tax.

SPECIAL FACTORS AFFECTING THE TEXAS FUND

  Texas'  economy  continues  to recover  from the  recession  that began in the
mid-1980s  after a collapse in oil  prices,  and the State  comptroller  expects
continued growth in the early 1990s. Also, since the mid-1980's, the economy has
diversified,  with the oil and gas industry  diminishing in relative  importance
while service-producing sectors provide the major sources of job growth.

  Based on information from the Texas Employment Commission, non-farm employment
has reached an all-time high of 7.8 million.  The unemployment  rate for 1994 is
estimated  at 6.4 percent  compared to a national  average of 6.1  percent.  The
Texas State  Government  ended fiscal year 1994 with a positive  cash balance in
the General  Fund.  This was the seventh  consecutive  year that the Texas State
Government had ended a fiscal year with a positive balance.

  On January 30, 1995, the Texas Supreme Court upheld the constitutionality of a
comprehensive  legislative revision to the system for financing the operation of
public  schools.  The  legislative  revisions  resulted  from a series  of court
decisions  commonly referred to as Edgewood v. Kirby, in which Texas courts have
declared the Texas school finance system  unconstitutional  under Texas law. The
Supreme Court's ruling  suggested that further changes might be needed in Texas'
school  finance  system in the near  future to  equalize  access to funding  for
capital  projects,  as well as  operations.  The Texas  Legislature is currently
considering  legislation  which  attempts  to  provide  such  equalization.  The
legislative  revision and further  efforts to equalize school funding may affect
the financial  condition of the Texas State  Government and certain Texas school
districts.

  Although it is anticipated  that most of the bonds held by the Texas Fund will
be  revenue   obligations  or  general   obligations  of  local  governments  or
authorities,  rather than general  obligations of the State of Texas itself, any
circumstances  that adversely affect the State's credit standing may also affect
the market value of these other bonds held by the Texas Fund, either directly or
indirectly,  as  a  result  of a  dependency  of  local  governments  and  other
authorities upon State aid and reimbursement programs.

  An  expanded   discussion   is  contained  in  the   statement  of  additional
information.

<PAGE>
                                                                       EXHIBIT B

                             REDUCED SALES CHARGES

  Initial  sales   charges  may  be  reduced  or   eliminated   for  persons  or
organizations  purchasing  Class A shares of a Fund alone or in combination with
Class A shares of other Keystone America Funds.

  For  purposes  of  qualifying  for reduced  sales  charges on  purchases  made
pursuant to Rights of  Accumulation or Letters of Intent,  the term  "Purchaser"
includes the following persons: an individual; an individual,  his or her spouse
and children under the age of 21; a trustee or other fiduciary of a single trust
estate  or  single  fiduciary   account   established  for  their  benefit;   an
organization  exempt from federal income tax under Section 501 (c)(3) or (13) of
the Code; a pension,  profit-sharing  or other employee  benefit plan whether or
not qualified under Section 401 of the Internal Revenue Code; or other organized
groups of persons,  whether  incorporated or not,  provided the organization has
been in existence  for at least six months and has some  purpose  other than the
purchase  of  redeemable  securities  of a  registered  investment  company at a
discount.  In order to qualify  for a lower  sales  charge,  all orders  from an
organized  group will have to be placed  through a single  investment  dealer or
other firm and identified as originating from a qualifying purchaser.

CONCURRENT PURCHASES

  For purposes of qualifying for a reduced sales charge, a Purchaser may combine
concurrent  direct  purchases of Class A shares of two or more of the  "Eligible
Funds," as defined  below.  For example,  if a Purchaser  concurrently  invested
$75,000 in one of the other  "Eligible  Funds" and $75,000 in a Fund,  the sales
charge  would be that  applicable  to a $150,000  purchase,  i.e.,  3.75% of the
offering price, as indicated in the Sales Charge schedule in the prospectus.

RIGHT OF ACCUMULATION

  In calculating  the sales charge  applicable to current  purchases of a Fund's
shares, a Purchaser is entitled to accumulate current purchases with the current
value of previously  purchased  Class A shares of the Fund and Class A shares of
certain other  eligible funds that are still held in (or exchanged for shares of
and are still held in) the same or another  eligible fund ("Eligible  Fund(s)").
The Eligible Funds presently  consist of the Keystone America Funds and Keystone
Liquid Trust.

  For example,  if a Purchaser  held shares  valued at $99,999 and  purchased an
additional $5,000, the sales charge for the $5,000 purchase would be at the next
lower sales  charge of 3.75% of the  offering  price as  indicated  in the Sales
Charge  schedule.  KIRC  must be  notified  at the  time of  purchase  that  the
Purchaser is entitled to a reduced sales charge, which reduction will be granted
subject to confirmation of the Purchaser's  holdings.  The Right of Accumulation
may be modified or discontinued at any time.

LETTER OF INTENT

  A Purchaser  may qualify for a reduced  sales  charge on a purchase of Class A
shares of the Fund alone or in  combination  with purchases of Class A shares of
any of the other  Eligible  Funds by completing  the Letter of Intent section of
the  application.  By  doing  so,  the  Purchaser  agrees  to  invest  within  a
thirteen-month  period a specified amount, which, if invested at one time, would
qualify  for a reduced  sales  charge.  Each  purchase  will be made at a public
offering price applicable to a single transaction of the dollar amount specified
on the application,  as described in this prospectus.  The Letter of Intent does
not  obligate  the  Purchaser  to  purchase,  nor a Fund  to  sell,  the  amount
indicated.

  After the Letter of Intent is received by KIRC,  each  investment made will be
entitled to the sales charge applicable to the level of investment  indicated on
the  application.  The Letter of Intent may be  back-dated  up to ninety days so
that any  investments  made in any of the Eligible  Funds  during the  preceding
ninety-day  period,  valued  at the  Purchaser's  cost,  can be  applied  toward
fulfillment of the Letter of Intent.  However,  there will be no refund of sales
charges  already paid during the ninety-day  period.  No retroactive  adjustment
will be made if purchases  exceed the amount  specified in the Letter of Intent.
Income and capital gains distributions taken in additional shares will not apply
toward completion of the Letter of Intent.

  If total  purchases  made  pursuant  to the Letter of Intent are less than the
amount specified, the Purchaser will be required to remit an amount equal to the
difference  between the sales  charge paid and the sales  charge  applicable  to
purchases  actually made. Out of the initial purchase (or subsequent  purchases,
if necessary), 5% of the dollar amount specified on the application will be held
in escrow by KIRC in the form of shares  registered in the Purchaser's name. The
escrowed shares will not be available for redemption, transfer or encumbrance by
the Purchaser until the Letter of Intent is completed or the higher sales charge
paid. All income and capital gains distributions on escrowed shares will be paid
to the Purchaser or his order.

  When the minimum  investment  specified  in the Letter of Intent is  completed
(either prior to or by the end of the thirteen-month period), the Purchaser will
be notified and the escrowed shares will be released. If the intended investment
is not  completed,  the  Purchaser  will be  asked  to  remit  to the  Principal
Underwriter any difference  between the sales charge on the amount specified and
on the amount actually attained.  If the Purchaser does not within 20 days after
written  request by the Principal  Underwriter or his dealer pay such difference
in sales charge,  KIRC will redeem an appropriate  number of the escrowed shares
in order to realize such difference.  Shares remaining after any such redemption
will be released  by KIRC.  Any  redemptions  made by the  Purchaser  during the
thirteen-month  period will be  subtracted  from the amount of the purchases for
purposes of determining whether the Letter of Intent has been completed.  In the
event of a total  redemption of the account prior to completion of the Letter of
Intent,  the  additional  sales charge due will be deducted from the proceeds of
the redemption and the balance will be forwarded to the Purchaser.

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

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

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

         The FUND is a non-diversified,  open-end management  investment company
commonly known as a mutual fund. The FUND was formed as a Massachusetts business
trust on  September  13, 1990.  The FUND is one of the thirty  funds  managed or
advised by Keystone  Investment  Management  Company  (formerly  named  Keystone
Custodian Funds, Inc.)  ("Keystone"),  the FUND's investment  adviser.  The FUND
currently consists of the following five separate series evidencing interests in
different  portfolios of securities:  Keystone  Florida Tax Free Fund,  Keystone
Massachusetts Tax Free Fund,  Keystone New York Insured Tax Free Fund,  Keystone
Pennsylvania Tax Free Fund and Keystone Texas Tax Free Fund (each, a "Fund," and
collectively,   the   "Funds").   The  Keystone   Pennsylvania   Tax  Free  Fund
("Pennsylvania  Fund") and the Keystone  Florida Tax Free Fund ("Florida  Fund")
were established on September 19, 1990. The Keystone Massachusetts Tax Free Fund
("Massachusetts  Fund"),  the Keystone New York Insured Tax Free Fund ("New York
Insured  Fund")  and the  Keystone  Texas  Tax Free  Fund  ("Texas  Fund")  were
established  on  February  21,  1992.  The  Massachusetts  Fund and the New York
Insured Fund were not offered to the public prior to February 4, 1994.

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

         For  special  factors  affecting  each  Fund,  see  Appendix  A to this
statement of additional information.

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

         Each Fund invests  primarily in municipal  obligations  that are exempt
from  federal  income tax and also exempt from  certain  specified  taxes in the
state for which it is named.  In  addition,  the Funds  invest in certain  other
securities as described below.

MUNICIPAL OBLIGATIONS

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

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

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

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

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

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

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

OTHER ELIGIBLE INVESTMENTS

         A Fund may invest up to 20% of its assets under ordinary circumstances,
and up to 100% of its assets for temporary  defensive  purposes in the following
types of instruments:  (1) commercial paper, including master demand notes, that
at the date of investment is rated A-1 (the highest grade by S&P),  PRIME-1 (the
highest  grade by  Moody's)  or, if not rated by such  services,  is issued by a
company  that at the date of  investment  has an  outstanding  issue  rated A or
better by S&P or Moody's; (2) obligations, including certificates of deposit and
bankers' acceptances,  of banks, or savings and loan associations,  that have at
least $1  billion  in assets  as of the date of their  most  recently  published
financial   statements  that  are  members  of  the  Federal  Deposit  Insurance
Corporation,  including U.S.  branches of foreign banks and foreign  branches of
U.S. banks;  (3) corporate  obligations  (maturing in 13 months or less) that at
the date of investment are rated A or better by S&P or Moody's;  (4) obligations
issued or guaranteed by the U.S.  government or by any agency or instrumentality
of the U.S.; (5) qualified "private activity"  industrial  development bonds the
income from which, while exempt from federal income tax under Section 103 of the
Code, is includable in the calculation of the federal  alternative  minimum tax;
and (6) municipal obligations, the income of which is exempt from federal income
tax,  but not exempt  from income tax in  Pennsylvania,  or which are not exempt
from personal  property or intangibles  tax in Florida or  Pennsylvania,  as the
case may be. Each Fund will  assume a temporary  defensive  position  when,  for
example,  Keystone  determines that market  conditions so warrant.  If a Fund is
investing defensively, it is not pursuing its objectives.

FUNDAMENTAL NATURE OF INVESTMENT OBJECTIVES

         The investment  objectives of each Fund are  fundamental and may not be
changed without approval of the holders of a majority of such Fund's outstanding
voting shares (which means the lesser of (1) 67% of the shares  represented at a
meeting at which more than 50% of the outstanding  shares are represented or (2)
more than 50% of the outstanding shares).

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

         The investment  restrictions  as summarized  below are  fundamental for
each Fund and may not be changed  without  the vote of a majority of such Fund's
outstanding voting shares. Unless otherwise stated, all references to the assets
of a Fund  are in  terms  of  current  market  value.  Each  Fund may not do the
following:

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

         (2)  invest  more than 10% of its  assets in  securities  with legal or
contractual  restrictions on resale or in securities for which market quotations
are not readily  available,  or in repurchase  agreements  maturing in more than
seven days;

         (3) issue senior  securities;  the purchase or sale of  securities on a
"when issued" basis,  or collateral  arrangement  with respect to the writing of
options on securities, are not deemed to be the issuance of a senior security;

         (4) borrow money or enter into reverse  repurchase  agreements,  except
that a Fund may enter into reverse  repurchase  agreements  or borrow money from
banks for temporary or emergency  purposes in aggregate  amounts up to one-third
of the value of the Fund's net assets; provided that while borrowings from banks
(not  including  reverse  repurchase  agreements)  exceed 5% of the  Fund's  net
assets,  any such  borrowings will be repaid before  additional  investments are
made;

         (5)  purchase  securities  on margin  except  that it may  obtain  such
short-term  credit as may be necessary  for the clearance of purchases and sales
of securities;

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

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

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

         (9) underwrite  securities of other  issuers,  except that the Fund may
purchase  securities from the issuer or others and dispose of such securities in
a manner consistent with its investment objective.

         The Funds are  non-diversified  under the federal  securities  laws. As
non-diversified  Funds, there is no restriction under the Investment Company Act
of 1940  ("1940  Act") on the  percentage  of assets that may be invested at any
time in the securities of any one issuer.  The Funds intend to comply,  however,
with the Code's diversification  requirements and other requirements  applicable
to  "regulated  investment  companies"  so that they will not be subject to U.S.
federal income tax on income and capital gain distributions to shareholders. For
this reason,  each Fund has adopted the additional  investment  restriction  set
forth  below,  which may not be changed  without the  approval of  shareholders.
Specifically,  a Fund may not (1)  purchase a  security  if more than 25% of the
Fund's  total  assets  would be invested in the  securities  of a single  issuer
(other than the U.S.  government,  its agencies and  instrumentalities);  or (2)
with respect to 50% of the Fund's total  assets,  if more than 5% of such assets
would be  invested in the  securities  of a single  issuer  (other than the U.S.
government, its agencies and instrumentalities).

         To the  extent  the Funds are not fully  diversified,  they may be more
susceptible to adverse economic,  political or regulatory developments affecting
a  single  issuer  than  would  be the  case  if the  Funds  were  more  broadly
diversified.

         As a matter of practice, each Fund treats reverse repurchase agreements
as borrowings for purposes of compliance  with the  limitations of the 1940 Act.
Reverse  repurchase  agreements will be taken into account along with borrowings
from  banks for  purposes  of the 5% limit set forth in the  fourth  fundamental
investment restriction above.

         Additional  restrictions adopted for each Fund, which may be changed by
the Board of Trustees, provide that a Fund may not purchase or retain securities
of an issuer if, to the knowledge of the FUND,  officers,  Trustees or Directors
of the FUND or  Keystone  each  owning  beneficially  more than 1/2 of 1% of the
securities of such issuer own in the aggregate more than 5% of the securities of
such  issuer,  or such persons or  management  personnel of the FUND or Keystone
have a  substantial  beneficial  interest  in the  securities  of  such  issuer.
Portfolio  securities  of a Fund may not be purchased  from or sold or loaned to
Keystone  or any  affiliate  thereof  or any of  their  Directors,  officers  or
employees.

         None of the Funds  presently  intends  to  invest  more than 25% of its
total assets in municipal  obligations  the payment of which depends on revenues
derived from a single  facility or similar  types of  facilities.  Since certain
municipal obligations may be related in such a way that an economic, business or
political  development  or change  affecting  one such security  could  likewise
affect the other  securities,  a change in this policy could result in increased
investment risk, but no change is presently contemplated.

         For  the  purposes  of  the  first  and  ninth  fundamental  investment
restrictions set forth above, each Fund will treat (1) each state, territory and
possession of the U.S., the District of Columbia and, if its assets and revenues
are separate  from those of the entity or entities  creating it, each  political
subdivision, agency and instrumentality of any one (or more, as in the case of a
multistate  authority or agency) of the foregoing as an issuer of all securities
that are backed  primarily  by its assets or  revenues;  (2) each  company as an
issuer of all  securities  that are backed  primarily by its assets or revenues;
and (3) each of the foregoing  entities as an issuer of all  securities  that it
guarantees;  provided,  however,  that for the purpose of the first  fundamental
investment  restriction  no entity shall be deemed to be an issuer of a security
that it  guarantees  so long as no more than 10% of a Fund's total assets (taken
at current  value)  are  invested  in  securities  guaranteed  by the entity and
securities of which it is otherwise deemed to be an issuer.

         The Texas Fund has undertaken to a state securities  authority that, so
long as the state  authority  requires and shares of the Fund are registered for
sale in that  state,  (1) the Fund will not  purchase  puts,  calls,  straddles,
spreads or combinations thereof, if by reason thereof the value of its aggregate
investment in such  securities will exceed 5% of its total assets except that it
may purchase  "stand-by  commitments"  and master demand notes; and (2) the Fund
will maintain 300% asset coverage on any leverage or bank borrowings.

         The FUND has undertaken to a state  securities  authority that, so long
as the state authority  requires and shares of a Fund are registered for sale in
that state,  the Fund will (1) not invest in real estate  limited  partnerships;
and (2) not invest in oil, gas or other mineral leases.

         Further,  the FUND has undertaken to a state securities authority that,
so long as the state authority  requires and shares of a Fund are registered for
sale in that state, all loans of portfolio securities will be made in accordance
with fair,  just and equitable  practice and the collateral  values of portfolio
securities loaned will be maintained at no less than 100% by "marking to market"
daily.

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

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

- -------------------------------------------------------------------------------
                    VALUATION AND REDEMPTION OF SECURITIES
- -------------------------------------------------------------------------------

         Current values for each Fund's  portfolio  securities may be determined
in the following manner:

         1.  securities for which market  quotations  are readily  available are
valued at the mean of the bid and asked prices at the time of valuation;

         2.  (a)  instruments  having  maturities  of  sixty  days or less  when
purchased are valued at amortized cost  (original  purchase cost as adjusted for
amortization  of premium or accretion of  discount),  which,  when combined with
accrued interest, approximates market;

            (b) investments maturing in more than sixty days when purchased that
are held on the  sixtieth  day prior to maturity  are valued at  amortized  cost
(market  value on the  sixtieth  day  adjusted  for  amortization  of premium or
accretion of discount), which, when combined with accrued interest, approximates
market;  and which,  in either case,  reflects  fair value as  determined by the
FUND's Board of Trustees;

         3. short-term instruments having maturities of more than sixty days for
which  market  quotations  are readily  available  are valued at current  market
value; and

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

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

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

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

GENERAL

         Generally, each Fund offers three classes of shares. Class A shares are
offered with a maximum  front end sales  charge of 4.75%  payable at the time of
purchase of Fund shares ("Front End Load Option").  Class B shares  purchased on
or after June 1, 1995 are subject to a contingent  deferred sales charge payable
upon  redemption  during the 72 month  period  following  the month of purchase.
Class B shares  purchased prior to June 1, 1995 are sold subject to a contingent
deferred sales charge payable upon redemption  within three calendar years after
the first year of purchase ("Back End Load Option"). Class B shares purchased on
or after June 1, 1995 that have been outstanding eight years following the month
of purchase will automatically convert to Class A shares without imposition of a
front-end  sales charge or exchange fee. Class B shares  purchased prior to June
1, 1995 that have been  outstanding  during seven  calendar years will similarly
convert to Class A shares.  (Conversion  of Class B shares  represented by stock
certificates  will  require  the return of the stock  certificates  to  Keystone
Investment Resource Center, Inc. ("KIRC").) Class C shares are sold subject to a
contingent  deferred sales charge payable upon redemption  within one year after
purchase  ("Level  Load  Option").  Class C shares are  available  only  through
dealers who have entered into special  distribution  agreements  with the FUND's
Principal  Underwriter.  The FUND's prospectus contains a general description of
how investors may buy shares of the FUND as well as a table of applicable  sales
charges for Class A shares, a discussion of reduced sales charges  applicable to
subsequent purchases,  and a description of applicable contingent deferred sales
charges.

CONTINGENT DEFERRED SALES CHARGES

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

CLASS A SHARES

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

CLASS B SHARES

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

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

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

CLASS C SHARES

         With certain  exceptions,  a Fund may impose a deferred sales charge of
1% on shares  redeemed  within one year after the date of purchase.  No deferred
sales charge is imposed on amounts redeemed thereafter.

         When imposed, the deferred sales charge is deducted from the redemption
proceeds  otherwise payable to you. The deferred sales charge is retained by the
Principal  Underwriter.  See  "Calculation of Contingent  Deferred Sales Charge"
below.

CALCULATION OF CONTINGENT DEFERRED SALES CHARGE

         Any  contingent  deferred  sales charge  imposed upon the redemption of
Class A, Class B or Class C shares is a percentage  of the lesser of (1) the net
asset  value  of the  shares  redeemed  or (2) the net  asset  value  at time of
purchase of such shares.

         No contingent  deferred  sales charge is imposed when amounts  redeemed
are derived from (1)  increases in the value of an account above the net cost of
such shares due to  increases  in the net asset  value per share of a Fund;  (2)
certain  shares  with  respect  to  which a Fund  did not  pay a  commission  on
issuance,  including shares acquired through reinvestment of dividend income and
capital gains  distributions;  (3) Certain Class A shares held for more than one
year or two years,  as the case may be, from the date of  purchase;  (4) Class B
shares  held during more than four  consecutive  calendar  years or more than 72
months  after the month of  purchase,  as the case may be; or (5) Class C shares
held for more than one year from date of purchase.

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

WAIVER OF SALES CHARGES

         Class A,  Class B or Class C shares of each  Fund may also be sold,  to
the  extent  permitted  by  applicable  law,  regulations,   interpretations  or
exemptions, at net asset value without the imposition of an initial sales charge
to (1) certain  officers,  Directors,  Trustees,  full-time  employees and sales
representatives   of  the  FUND,   Keystone   Management,   Keystone,   Keystone
Investments, Inc. (formerly Keystone Group, Inc.), ("Keystone Investments"), one
of their subsidiaries or the Principal  Underwriter,  who have been such for not
less than ninety days; (2) a pension and profit-sharing plan established by such
companies, their subsidiaries and affiliates, for the benefit of their officers,
Directors,  Trustees,  full-time employees and sales  representatives;  or (3) a
registered  representative  of a firm with a dealer agreement with the Principal
Underwriter,  provided,  however,  that all such sales are made upon the written
assurance  that  the  purchase  is made  for  investment  purposes  and that the
securities will not be resold except through redemption by the FUND.

         No initial sales charge is charged on a purchase of shares of a Fund by
a bank or trust  company  in a single  account in the name of such bank or trust
company as trustee if the  initial  investment  in shares of one of the Funds or
any fund in the Keystone Investments Family of Funds is at least $500,000.

         In  addition,  no  contingent  deferred  sales  charge is  imposed on a
redemption  of shares of a Fund in the event of (1) death or  disability  of the

                             DISTRIBUTION PLANS
- --------------------------------------------------------------------------------

         Rule 12b-1 under the 1940 Act permits investment companies, such as the
FUND, to use their assets to bear expenses of distributing  their shares if they
comply  with  various  conditions,  including  adoption of a  distribution  plan
containing  certain  provisions set forth in Rule 12b-1.  Each Fund's Class A, B
and C  Distribution  Plans have been  approved by the FUND's  Board of Trustees,
including a majority of the Trustees who are not interested persons of the FUND,
as defined in the 1940 Act ("Independent  Trustees"),  and the Trustees who have
no  direct  or  indirect  financial  interest  in the  Distribution  Plan or any
agreement  related  thereto (the "Rule 12b-1  Trustees," who are the same as the
Independent Trustees). Each Class A, B, and C Distribution Plan, a "Distribution
Plan," and collectively, "Distribution Plans".

DISTRIBUTION PLANS IN GENERAL

         The National Association of Securities Dealers, Inc. ("NASD") currently
limits the amount that a Fund may pay annually in distribution costs for sale of
its shares and shareholder  service fees. The rule limits annual expenditures to
1% of the aggregate  average daily net asset value of its shares, of which 0.75%
may be  used  to pay  such  distribution  costs  and  0.25%  may be  used to pay
shareholder  service fees. The NASD rule also limits the aggregate amount that a
Fund may pay for such distribution costs to 6.25% of gross share sales since the
inception  of the 12b-1  Plan,  plus  interest at the prime rate plus 1% on such
amounts (less any contingent  deferred sales charges paid by shareholders to the
Principal Underwriter).

CLASS A DISTRIBUTION PLAN

         The Class A  Distribution  Plan  provides  that a Fund may expend daily
amounts at an annual rate currently limited to up to 0.15% of the Fund's average
daily net asset value  attributable  to Class A shares to finance  any  activity
that is primarily  intended to result in the sale of Class A shares,  including,
without  limitation,   expenditures   consisting  of  payments  to  a  principal
underwriter  (currently  the  Principal  Underwriter)  of a Fund to  enable  the
Principal Underwriter to pay or to have paid to others who sell Class A shares a
service  or other  fee,  at such  intervals  as the  Principal  Underwriter  may
determine,  in respect of Class A shares  previously sold by any such others and
remaining  outstanding  during the period in respect of which such fee is or has
been paid.

         Amounts  paid  by a Fund  under  its  Class  A  Distribution  Plan  are
currently used to pay others, such as dealers, service fees at an annual rate of
up to 0.15% of the average net asset value of Class A shares sold by such others
and remaining outstanding on the books of the Fund for specific periods.

CLASS B DISTRIBUTION PLANS

         Each Fund has  adopted  Distribution  Plans for its Class B shares that
provide  that a Fund may expend  daily  amounts at an annual rate of up to 1.00%
(currently  limited  to  0.90%) of the  Fund's  average  daily  net asset  value
attributable  to  Class B shares  to  finance  any  activity  that is  primarily
intended to result in the sale of Class B shares, including, without limitation,
expenditures  consisting  of payments to the principal  underwriter  of the Fund
(currently the Principal Underwriter) (1) to enable the Principal Underwriter to
pay to others  (dealers)  commissions  in respect  of Class B shares  sold since
inception of the Distribution Plans; and (2) to enable the Principal Underwriter
to pay or to have  paid to  others  a  service  fee,  at such  intervals  as the
Principal Underwriter may determine,  in respect of Class B shares maintained by
any such recipients outstanding on the books of the Fund for specified periods.

         The  Principal  Underwriter  generally  reallows to brokers or others a
commission equal to 4.00% of the price paid for each Class B share sold plus the
first year's service fee in advance in the amount of 0.15% of the price paid for
each Class B share sold. Beginning approximately 12 months after the purchase of
a Class B share,  the broker or other party  receives  service fees at an annual
rate of  0.15% of the  average  daily  net  asset  value  of such  Class B share
maintained by the recipient  outstanding  on the books of the Fund for specified
periods.

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

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

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

CLASS C DISTRIBUTION PLAN

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

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

DISTRIBUTION PLANS - GENERAL

         Each of the Distribution Plans may be terminated at any time by vote of
the Rule 12b-1  Trustees  or by a vote of a majority of the  outstanding  voting
shares of the respective Class. For the Florida Fund, the Pennsylvania Fund, the
Texas Fund, the  Massachusetts  Fund and the New York Insured Fund  unreimbursed
Class B Distribution  Plan expenses at March 31, 1995 were $3,196,058  (6.12% of
net assets),  $1,923,455 (6.27% of net assets),  $145,495 (6.73% of net assets),
$384,672 (6.24% of net assets) and $728,940 (6.26% of net assets), respectively.

         Any change in a Distribution  Plan that would  materially  increase the
distribution  expenses of the affected Fund provided for in a Distribution  Plan
requires the Fund's shareholders'  approval.  Otherwise,  the Distribution Plans
may be amended by the Trustees, including the Rule 12b-1 Trustees.

         While the Distribution  Plans are in effect,  the FUND will be required
to commit the selection and nomination of candidates for Independent Trustees to
the discretion of the Independent Trustees.

         The total amounts paid by a Fund under the foregoing  arrangements  may
not exceed the maximum  Distribution Plan limit specified above, and the amounts
and purposes of expenditures  under a Distribution  Plan must be reported to the
Rule 12b-1  Trustees  quarterly.  The Rule 12b-1 Trustees may require or approve
changes in the  implementation  or operation of a Distribution Plan and may also
require  that total  expenditures  by a Fund under a  Distribution  Plan be kept
within limits lower than the maximum amount permitted by a Distribution  Plan as
stated above.

         During  the  fiscal  year  ended  March 31,  1995,  the  Florida  Fund,
Pennsylvania Fund, Texas Fund,  Massachusetts Fund and the New York Insured Fund
paid the Principal Underwriter (1) $66,246,  $44,697, $2,847, $1,829 and $3,025,
respectively,  pursuant to each Fund's Class A Distribution  Plan; (2) $345,221,
$244,404,  $18,613, $40,387 and $70,227,  respectively,  pursuant to each Fund's
Class B  Distribution  Plan; and (3) $140,405,  $81,781,  $5,377,  $15,014,  and
$15,895, respectively, pursuant to each Fund's Class C Distribution Plan.

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

0.35%             of the next                                $ 100,000,000, plus

0.25%             of amounts over                            $ 500,000,000

         The  Advisory  Agreement  continues in effect from year to year only if

majority  of the  outstanding  shares of each Fund,  and such  renewal  has been
approved by the vote of a majority of the Independent Trustees cast in person at
a meeting  called  for the  purpose  of voting on such  approval.  The  Advisory
Agreement may be terminated,  without penalty, on 60 days' written notice by the
FUND's  Board of Trustees or by a vote of a majority  of  outstanding  shares of
each  Fund.  The  Advisory  Agreement  will  terminate  automatically  upon  its
"assignment" as that term is defined in the 1940 Act.

         During  the  year  ended  March  31,  1993,  the  Florida  Fund and the
Pennsylvania  Fund  paid  or  accrued  to  Keystone  investment  management  and
administrative services fees of $199,288 and $138,570, respectively.  During the
period  ended  March 31,  1993,  the  Texas  Fund paid or  accrued  to  Keystone
investment management and administrative services fees of $8,092.

Pennsylvania  Fund,  and the Texas Fund paid or accrued to  Keystone  investment
management and administrative services fees of $363,939,  $291,982, and $22,246,

expenses  of the FUND's  Class A, B and C shares to 0.75%,  1.50%,  and 1.50% of
average daily net assets, respectively. Thereafter, a redetermination of whether
to  continue  these  expense  limitations  will be made.  Keystone  would not be
required to make such reimbursement to any Fund to the extent it would result in
the Fund's  inability  to qualify as a regulated  investment  company  under the
Code. In accordance  with  voluntary  expense  limitations  in effect during the
fiscal year ended March 31, 1994,  Keystone  reimbursed  the Florida  Fund,  the

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

         The FUND has  entered  into a  Principal  Underwriting  Agreement  (the
"Underwriting  Agreement") dated August 19, 1993 with the Principal Underwriter,
a wholly-owned subsidiary of Keystone. The Principal Underwriter,  as agent, has
agreed to use its best efforts to find purchasers for the shares.  The Principal
Underwriter may retain and employ representatives to promote distribution of the
shares and may  obtain  orders  from  brokers,  dealers  and  others,  acting as
principals,  for sales of shares to them. The  Underwriting  Agreement  provides
that the Principal Underwriter will bear the expense of preparing,  printing and
distributing  advertising and sales literature and  prospectuses  used by it. In
its capacity as principal  underwriter,  the Principal  Underwriter  may receive
payments from each Fund pursuant to such Fund's Distribution Plan.

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

         The  FUND  has  agreed  under  the  Underwriting  Agreement  to pay all
expenses in  connection  with  registration  of the shares of its Funds with the
Commission as well as auditing and filing fees in connection  with  registration
of such shares  under the  various  state  "blue-sky"  laws,  and the  Principal
Underwriter assumes the cost of sales literature and preparation of prospectuses
used by it and certain other expenses.

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

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

         The  Underwriting  Agreement  provides that it will remain in effect as
long as its terms and  continuance are approved by a majority of the FUND's Rule
12b-1 Trustees at least annually at a meeting called for that purpose and if its
continuance  is  approved  annually  by vote of a  majority  of the  Rule  12b-1
Trustees  or by vote of a majority  of the  outstanding  shares of the  affected
Funds.

         The Underwriting  Agreement may be terminated,  without penalty,  on 60
days'  written  notice  by the  FUND's  Rule  12b-1  Trustees  or the  Principal
Underwriter  or terminated as to any Fund by a vote of a majority of outstanding
shares of such Fund. The  Underwriting  Agreement  will terminate  automatically
upon its "assignment" as that term is defined in the 1940 Act.

- --------------------------------------------------------------------------------
                                  BROKERAGE
- --------------------------------------------------------------------------------

         It is the policy of the FUND,  in effecting  transactions  in portfolio
securities,  to seek best execution of orders at the most favorable prices.  The
determination  of what may constitute  best execution and price in the execution
of a securities  transaction  by a broker  involves a number of  considerations,
including, without limitation, the overall direct net economic result to a Fund,
involving both price paid or received and any  commissions and other costs paid,
the efficiency with which the transaction is effected, the ability to effect the
transaction  at all where a large block is  involved,  the  availability  of the
broker to stand  ready to  execute  potentially  difficult  transactions  in the
future and the financial strength and stability of the broker. Management weighs
such  considerations  in  determining  the overall  reasonableness  of brokerage
commissions paid.

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

         The FUND expects that purchases and sales of municipal  obligations and
temporary  instruments  usually  will  be  principal   transactions.   Municipal
obligations and temporary  instruments are normally  purchased directly from the
issuer or from an underwriter or market maker for the securities.  There usually
will be no brokerage  commissions  paid by a Fund for such purchases.  Purchases
from  underwriters will include the underwriting  commission or concession,  and
purchases from dealers  serving as market makers will include a dealer's mark up
or  reflect  a  dealer's  mark  down.   Where   transactions  are  made  in  the
over-the-counter  market,  each Fund will deal with primary market makers unless
more favorable prices are otherwise obtainable.

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

         Neither Keystone nor the Funds intend to place securities  transactions
with any particular broker-dealer or group thereof. The FUND's Board of Trustees
has determined, however, that the Funds may follow a policy of considering sales
of shares as a factor in the selection of  broker-dealers  to execute  portfolio
transactions,  subject to the  requirements  of best  execution,  including best
price, described above.

         The  policy  of the  FUND  with  respect  to  brokerage  is and will be
reviewed  by the  FUND's  Board of  Trustees  from time to time.  Because of the
possibility  of  further  regulatory   developments   affecting  the  securities
exchanges  and brokerage  practices  generally,  the foregoing  practices may be
changed, modified or eliminated.

         Investment  decisions for the Funds are made  independently by Keystone
from those of the other funds and investment  accounts  managed by Keystone.  It
may frequently  develop that the same investment  decision is made for more than
one fund.  Simultaneous  transactions  are inevitable  when the same security is
suitable for the investment objective of more than one account. When two or more
funds or accounts are engaged in the purchase or sale of the same security,  the
transactions  are allocated as to amount in  accordance  with a formula which is
equitable  to each fund or  account.  It is  recognized  that in some cases this
system could have a detrimental effect on the price or volume of the security as
far as the Funds are concerned. In other cases, however, it is believed that the
ability of a Fund to  participate  in volume  transactions  will produce  better
executions for the Fund.

         For the fiscal  years and/or  periods,  as the case may be, ended March
31, 1993, March 31, 1994 and March 31, 1995, the
Funds did not pay any brokerage commissions.

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

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

MASSACHUSETTS BUSINESS TRUST

         The  FUND  is  a  Massachusetts  business  trust  established  under  a
Declaration of Trust dated September 13, 1990 ("Declaration of Trust"). The FUND
is similar in most respects to a business corporation. The principal distinction
between  the  FUND  and a  corporation  relates  to  the  shareholder  liability
described  below.  A copy of the  Declaration of Trust is filed as an exhibit to
the FUND's Registration Statement.  This summary is qualified in its entirety by
reference to the Declaration of Trust.

DESCRIPTION OF SHARES

         The Declaration of Trust authorizes the issuance of an unlimited number
of shares of  beneficial  interest  of classes  of shares.  Each share of a Fund
represents an equal proportionate interest in such Fund with each other share of
the Fund. Generally, each Fund currently issues three classes of shares, but may
issue additional classes or series of shares. Upon liquidation,  Fund shares are
entitled  to a pro rata  share of the Fund based on the  relative  net assets of
each class.  Shareholders  have no preemptive or conversion  rights.  Shares are
transferable,  redeemable  and  fully  assignable  as  collateral.  There are no
sinking fund provisions.

SHAREHOLDER LIABILITY

         Pursuant  to  certain  decisions  of  the  Supreme  Judicial  Court  of
Massachusetts, shareholders of a Massachusetts business trust may, under certain
circumstances,  be held personally liable as partners for the obligations of the
trust.  If the  FUND  were  held to be a  partnership,  the  possibility  of the
shareholders incurring financial loss for that reason appears remote because the
FUND's  Declaration  of Trust (1) contains an express  disclaimer of shareholder
liability  for  obligations  of the  FUND;  (2)  requires  that  notice  of such
disclaimer be given in each agreement,  obligation or instrument entered into or
executed by the FUND or the Trustees;  and (3) provides for  indemnification out
of FUND property for any shareholder held personally  liable for the obligations
of the FUND.

VOTING RIGHTS

         Under the Declaration of Trust, the FUND does not hold annual meetings.
Shares of a Fund are  entitled  to one vote per  share.  Shares  generally  vote
together as one class on all matters, except that each Fund has exclusive voting
rights with respect to matters which affect only that Fund. Classes of shares of
a Fund have equal voting  rights  except that each class of shares has exclusive
voting rights with respect to its respective Distribution Plan. No amendment may
be made to the  Declaration of Trust that adversely  affects any class of shares
without the  approval  of a majority  of the shares of that  class.  Shares have
non-cumulative  voting rights,  which means that the holders of more than 50% of
the shares voting for the election of Trustees can elect 100% of the Trustees to
be elected at a meeting and, in such event,  the holders of the remaining 50% or
less of the shares voting will not be able to elect any Trustees.

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

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

LIMITATION OF TRUSTEES' LIABILITY

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

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

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

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

cumulative total return (including contingent deferred sales charge) for Class C
of  the  Massachusetts  and  New  York  Insured  Fund  was  -2.39%  and  -0.21%,
respectively.

CURRENT YIELD AND TAX EQUIVALENT YIELD

         Current  yield  quotations  as they  may  appear  from  time to time in
advertisements  will  consist of a quotation  based on a 30-day period ended on
the date of the most recent  balance  sheet of a Fund,  computed by dividing the
net investment income per share earned during the period by the maximum offering
price per share on the last day of the base  period.  Such  yield  will  include
income from sources other than municipal obligations, if any.

         For the 30-day period ended March 31, 1995,  the current yield of Class
A of the Florida Fund, the Pennsylvania  Fund, the Texas Fund, the Massachusetts
Fund and the New York Insured  Fund was 5.37%,  5.33%,  5.32%,  5.61% and 5.15%,
respectively.

         For the 30-day period ended March 31, 1995,  the current yield of Class
B of the Florida Fund, the Pennsylvania  Fund, the Texas Fund, the Massachusetts
Fund and the New York Insured  Fund was 4.89%,  4.85%,  4.84%,  5.13% and 4.65%,
respectively.

         For the 30-day period ended March 31, 1995,  the current yield of Class
C of the Florida Fund, the Pennsylvania  Fund, the Texas Fund, the Massachusetts
Fund and the New York Insured  Fund was 4.89%,  4.85%,  4.83%,  5.14% and 4.64%,
respectively.

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

         The tax equivalent yield for the 30-day period ended March 31, 1995 for
Class A of the  Florida  Fund,  the  Pennsylvania  Fund,  the  Texas  Fund,  the
Massachusetts Fund and the New York Insured Fund was 7.78%,  7.72%, 7.71%, 8.13%
and 7.46%, respectively.

         The tax equivalent yield for the 30-day period ended March 31, 1995 for
Class B of the  Florida  Fund,  the  Pennsylvania  Fund,  the  Texas  Fund,  the
Massachusetts Fund and the New York Insured Fund was 7.09%,  7.03%, 7.01%, 7.43%
and 6.74%, respectively.

         The tax equivalent yield for the 30-day period ended March 31, 1995 for
Class C of the  Florida  Fund,  the  Pennsylvania  Fund,  the  Texas  Fund,  the
Massachusetts Fund and the New York Insured Fund was 7.09%,  7.03%, 7.00%, 7.45%
and 6.72%, respectively.

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

                         KEYSTONE FLORIDA TAX FREE FUND

REVENUES

     The  State  accounts  for  its  receipts  using  fund  accounting.  It  has
established the General Revenue Fund, the Working Capital Fund and various other
trust funds,  which are  maintained for the receipt of monies which under law or
trust agreements must be maintained separately.

   
     The General  Revenue Fund consists of all monies received by the State from
every  source  whatsoever  which are not  allocable  to the other  funds.  Major
sources of tax revenues for the General  Revenue Fund are the sales and use tax,
the corporate  income tax, and the intangible  personal  property tax, which are
projected for fiscal year 1995-96 to amount to 71%, 8% and 4%, respectively,  of
the total receipts of that fund.
    

     The Florida  Constitution and its statutes mandate that the State budget as
a whole and each  separate  fund within the State budget be kept in balance from
currently available revenues for each fiscal year.

SALES AND USE TAX

   
     The greatest  single source of tax receipts in Florida is the sales and use
tax,  which is  projected  to amount to 10.3  billion  dollars  for fiscal  year
1995-96.  The sales tax is 6% of the sales price of tangible  personal  property
sold at retail in the state.  The use tax is 6% of the cash price or fair market
value of tangible  personal  property when it is not sold but is used, or stored
for  use,  in the  State.  In other  words,  the use tax  applies  to the use of
tangible personal property in Florida,  which was purchased in another state but
would have been subject to the sales tax if purchased in Florida.  Approximately
10% of the sales tax is designated for local  governments  and is distributed to
the  respective  counties  in  which  collected  for  use by such  counties  and
municipalities therein. In addition to this distribution,  local governments may
(by referendum) assess a 1% sales surtax within their county. Proceeds from this
local option sales surtax can be earmarked for funding  countywide bus and rapid
transit systems, local infrastructure construction and maintenance,  and medical
care for indigents, as set forth in Section 212.055(2), of the Florida Statutes.
    

     The two taxes, sales and use, stand as complements to each other, and taken
together  provide a uniform tax upon either the sale at retail or the use of all
tangible personal property irrespective of where it may have been purchased. The
sales  tax also  includes  a levy on the  following:  (i)  rentals  on  tangible
personal  property  and  accommodations  in  hotels,  motels,  some  apartments,
offices,  real estate,  parking and storage places in parking lots,  garages and
marinas for motor  vehicles or boats;  (ii)  admissions to places of amusements,
most sports and recreation events; (iii) utilities,  except those used in homes;
and  (iv)  restaurant  meals  and  expendables  used  in  radio  and  television
broadcasting.  Exemptions  include:  groceries;  medicines;  hospital  rooms and
meals; seeds, feeds,  fertilizers and farm crop protection materials;  purchases
by religious,  charitable and educational nonprofit  institutions;  professional
services,  insurance  and certain  personal  service  transactions;  newspapers;
apartments  used as permanent  dwellings;  and  kindergarten  through  community
college athletic contests or amateur plays.

OTHER STATE TAXES

     Other  taxes which  Florida  levies  include the motor fuel tax,  corporate
income tax,  intangible  property tax,  documentary  stamp tax,  gross  receipts
utilities tax and severance tax on the  production of oil and gas and the mining
of solid minerals, such as phosphate and sulfur.

LOCAL GOVERNMENT DEBT

     Numerous government units,  counties,  cities, school districts and special
taxing districts,  issue general  obligation bonds backed by their taxing power.
State  and local  government  units may  issue  revenue  obligations,  which are
supported by the revenues generated from the particular projects or enterprises.
Examples  include  obligations  issued to finance the  construction of water and
sewer systems, health care facilities and educational facilities. In some cases,
sewer or water revenue obligations may be additionally secured by the full faith
and credit of the State.

OTHER FACTORS

     The performance of the obligations issued by Florida,  its  municipalities,
subdivisions and instrumentalities are in part tied to state-wide,  regional and
local  conditions  within Florida.  Adverse  changes to state-wide,  regional or
local  economies  may  adversely  affect the  creditworthiness  of Florida,  its
municipalities,  etc. Also,  some revenue  obligations  may be issued to finance
construction of capital projects which are leased to  nongovernmental  entities.
Adverse  economic  conditions  might affect those lessees' ability to meet their
obligations  to the  respective  governmental  authority  which  in  turn  might
jeopardize  the  repayment of the  principal of, or the interest on, the revenue
obligations.


                      KEYSTONE MASSACHUSETTS TAX FREE FUND

GENERAL

     The  Commonwealth's  constitution  requires,  in effect,  that its  budget,
though not necessarily its operating  expenditures and revenue, be balanced each
year. In addition,  the Commonwealth has certain budgetary procedures and fiscal
controls in place that are designed to ensure that  sufficient cash is available
to meet the Commonwealth's  obligations,  that state expenditures are consistent
with  periodic  allotments  of  annual  appropriations  and that the  funds  are
expended  consistent  with  statutory and public  purposes.  The General Fund is
generally  regarded as the  principal  indicator  of whether the  Commonwealth's
operating  revenues and expenses are in balance.  The other principal  operating
funds (the Local Aid Fund and the  Highway  Fund) are  customarily  funded to at
least a zero balance.

     Although the Commonwealth experienced quite a slowdown during the recession
with  spending  exceeding  revenues,  beginning  in 1991  the  Commonwealth  has
experienced a turn-around  in its finances  with  revenues  exceeding  spending.
Budgeted  expenditures for fiscal 1989, 1990 and 1991 were approximately $12.643
billion,  $13.260  billion  and $13.659  billion,  respectively  while  budgeted
revenues and other sources for those years were approximately  $11.970,  $12.008
billion and $13.634 billion, respectively. By comparison,  budgeted revenues and
other sources  increased by approximately  0.7% from fiscal 1991 to fiscal 1992,
while tax revenues increased by 5.4% for the same period.  Budgeted expenditures
in  fiscal  1992  were  1.7%  lower  than  fiscal  1991  budgeted  expenditures.
Furthermore,  total  revenues  and  other  sources  for  fiscal  1993  increased
approximately  6.9% from fiscal 1992,  while tax revenues  increased by 4.7% for
the same  period.  Budgeted  expenditures  and other  uses in  fiscal  1993 were
approximately  9.6% higher than fiscal 1992  expenditures  and other uses. As of
1993  fiscal  year  end,  the  Commonwealth  showed a year-end cash  position of
approximately  $622.2  million,  as compared  to a projected  position of $485.1
million.  By comparison,  the Commonwealth  ended the 1989 fiscal year with fund
balances in deficit by $319.3 million.

     The fiscal  1994  budget,  as signed  into law by the  Governor on July 19,
1993, provides for expenditures of approximately $15.500 billion, an increase of
5.5% over fiscal 1993 levels. Budgeted revenues for fiscal 1994 are estimated to
be  approximately  $15.483  billion,  which  is 5.3%  higher  than  fiscal  1993
expenditures.  This amount  includes  estimated  tax  revenues of  approximately
$10.560 billion,  which is 6.3% higher than fiscal 1993 tax revenues. For fiscal
1994, a combined balance of $541.4 million is expected in the  stabilization and
undesignated  general  funds.  The fiscal  1994  budget is based  upon  numerous
spending and revenue estimates, the achievement of which cannot be assured.

     In June 1993, new comprehensive  education reform  legislation was enacted.
It  is  expected  that  this   legislation  will  require  annual  increases  in
expenditures  for education  purposes  above fiscal 1993 base spending of $1.289
billion of  approximately  $175 million in fiscal  1994,  $141 million in fiscal
1995 and $662  million in fiscal  1996.  The fiscal  1994 budget  includes  $175
million  in  appropriations  to satisfy  this  legislation.  Municipalities  and
agencies  of the  Commonwealth  are  experiencing  the  same  economic  effects.
Moreover,  they are affected by the  financial  condition  of the  Commonwealth,
because they receive substantial funding from the Commonwealth.

LIMITATIONS ON TAX REVENUES

     In Massachusetts,  efforts to limit and reduce levels of taxation have been
underway for several  years.  Limits were  established  on state tax revenues by
legislation  enacted on October 25, 1986 and by an initiative  petition approved
by the voters on November 4, 1986. The two measures are  inconsistent in several
respects.

     Chapter 62F, which was added to the General Laws by initiative  petition in
November 1986, establishes a state tax revenue growth limit for each fiscal year
equal to the average  positive rate of growth in total wages and salaries in the
Commonwealth,  as reported by the federal government,  during the three calendar
years  immediately  preceding  the end of such  fiscal  year.  Chapter  62F also
requires that  allowable  state tax revenues be reduced by the aggregate  amount
received by local  governmental  units from any newly  authorized  or  increased
local option taxes or excises. Any excess in state tax revenue collections for a
given fiscal year over the prescribed limit, as determined by the State Auditor,
is to be  applied  as a credit  against  the then  current  personal  income tax
liability of all  taxpayers in the  Commonwealth  in  proportion to the personal
income tax liability of all taxpayers in the  Commonwealth  for the  immediately
preceding tax year. The legislation enacted in October 1986, which added Chapter
29B to the General Laws,  also  establishes  an allowable  state revenue  growth
factor by reference to total wages and  salaries in the  Commonwealth.  However,
rather than utilizing a three-year  average wage and salary growth rate, as used
by Chapter 62F,  Chapter 29B utilizes an allowable  state revenue  growth factor
equal to 1/3 o the positive  percentage gain in Massachusetts wages and salaries
during the three calendar years immediately  preceding the end of a given fiscal
year.

     Tax revenues in fiscal 1989  through  fiscal 1993 were lower than the limit
set  by  either   Chapter  62F  or  Chapter  29B.  The   Executive   Office  for
Administration and Finance currently estimates that state tax revenues in fiscal
1994 will not reach the limit imposed by either of these statutes.

     In January 1992, the Governor  announced his intention to seek an amendment
to the state  constitution  that would require any  Commonwealth tax increase to
receive at least a two-thirds majority vote in each house of the Legislature. No
action has yet been taken on this proposal.

PROPOSITION 2 1/2

     In November  1980,  voters in the  Commonwealth  approved a  statewide  tax
limitation  initiative  petition,  commonly  known  as  Proposition  2  1/2,  to
constrain levels of property  taxation and to limit the charges and fees imposed
on  cities  and  towns  by  certain  governmental  entities,   including  county
governments.  Proposition 2 1/2 is not a provision of the state constitution and
accordingly is subject to amendment or repeal by the legislature.  Proposition 2
1/2,  as amended to date,  limits the  property  taxes that may be levied by any
city or town in any  fiscal  year to the lesser of (i) 2.5% of the full and fair
cash valuation of the real estate and personal property  therein,  and (ii) 2.5%
over the previous year's levy limit plus any growth in the tax base from certain
new  construction  and parcel  subdivisions.  Proposition  2 1/2 also limits any
increase  in the charges and fees  assessed  by certain  governmental  entities,
including county governments,  on cities and towns to the sum of (i) 2.5% of the
total  charges  and fees  imposed in the  preceding  fiscal  year,  and (ii) any
increase  in charges  for  services  customarily  provided  locally or  services
obtained by the city or town at its option.

     Many communities have responded to the limitations imposed by Proposition 2
1/2 through statutorily  permitted  overrides and exclusions.  Override activity
peaked in fiscal 1991, when 182 communities  attempted votes on one of the three
types of referenda questions (override of levy limit, exclusion of debt service,
or  exclusion  of capital  expenditures)  and 100 passed at least one  question,
adding $58.5 million to their levy limits. In fiscal 1992, 67 of 143 communities
had successful  votes  totalling  $31.0 million.  In fiscal 1993, 83 communities
attempted a vote;  two-thirds of them (56) passed  questions  aggregating  $16.4
million.  Although  Proposition 2 1/2 will continue to constrain  local property
tax revenues, significant capacity exists for overrides in every community.

LOCAL AID

     During the  1980's,  the  Commonwealth  increased  payments  to its cities,
towns,  and regional  school  districts  ("Local Aid") to mitigate the impact of
Proposition 2 1/2 on local programs and services. In fiscal 1994,  approximately
28.7% of the  Commonwealth's  budget is  estimated to be allocated to Local Aid.
Local Aid payments to cities, towns, and regional school districts take the form
of both direct and indirect assistance.

     Direct  local aid  decreased  from $2.961  billion in fiscal 1989 to $2.328
billion in fiscal 1992 and  increased to $2.547  billion in fiscal  1993.  It is
estimated  that fiscal  1994  expenditures  for direct  Local Aid will be $2.737
billion, which is an increase of approximately 7.5% above the fiscal 1993 level.
The additional amount of indirect Local Aid provided over and above direct Local
Aid was  approximately  $1.717  billion in fiscal 1993. It is estimated  that in
fiscal 1994  approximately  $1.717  billion of  indirect  Local Aid will also be
paid.

     A  statute  adopted  by voter  initiative  petition  at the  November  1990
statewide  election regulates the distribution of Local Aid to cities and towns,
by requiring,  subject to  appropriation,  that no less than 40% of  collections
from personal income taxes,  sales and use taxes,  corporate  excise taxes,  and
lottery fund  proceeds be  distributed  to cities and towns.  Under the law, the
Local Aid distribution to each city or town would equal no less than 100% of the
total Local Aid received for fiscal 1989. Distributions in excess of fiscal 1989
levels would be based on new formulas.  By its terms, the new formula would have
called for a substantial  increase in direct Local Aid in fiscal 1992, and would
call for such an increase in fiscal 1993 and subsequent  years.  However,  Local
Aid payments expressly remain subject to annual  appropriation,  and fiscal 1992
and fiscal  1993  appropriations  for Local Aid did not meet,  and  fiscal  1994
appropriations for Local Aid do not meet, the levels set forth in the initiative
law.

COMMONWEALTH EXPENDITURES

     From  fiscal  1989  to  fiscal  1991,  total  program  expenditures  of the
Commonwealth  (which  excludes  interfund  transfers) in its budgeted  operating
funds  increased at an average annual rate of  approximately  4.0%.  Fiscal 1992
program  expenditures  were  $13.420  billion,  or 1.7% lower  than 1992  fiscal
program expenditures.

     For fiscal 1993, program expenditures were $14.696 billion,  representing a
9.6%  increase  from fiscal  1992.  It is  estimated  that  fiscal 1994  program
expenditures  will total $15.500  billion,  an increase of 5.5% over fiscal 1993
levels.

     Commonwealth  expenditures  since fiscal 1989 largely  reflect  significant
growth  in  several  programs  and  services   provided  by  the   Commonwealth,
principally Local Aid,  Medicaid and group health  insurance,  public assistance
programs,  debt  service,  pensions,  higher  education  and  assistance  to the
Massachusetts Bay Transportation Authority and regional transit authorities.

     The  Commonwealth  is responsible  for the payment of pension  benefits for
state employees and for school teachers  throughout the state.  The Commonwealth
is also  responsible for cost of living  increases  payable to local  government
retirees. State pension expenditures have risen dramatically as the Commonwealth
has appropriated  moneys to partially address the unfunded  liabilities that had
accumulated  over  several  decades  of  "pay-as-you-go"  administration  of the
pension systems for which it is responsible. For several years during the 1980s,
the Commonwealth made substantial direct  appropriations to pension reserves, in
addition to paying current benefits. In 1988, the Commonwealth adopted a funding
schedule under which it is required to fund future pension liabilities currently
and to  amortize  the  accumulated  unfunded  liabilities  over 40 years.  Total
pension  expenditures  increased  at an average  annual rate of 7.1% from $659.7
million in fiscal 1989 to $868.2 million in fiscal 1993.  The estimated  pension
expenditures for fiscal 1994 are $951.0 million representing an increase of 9.5%
over fiscal 1993 expenditures.

OTHER FACTORS

     Many factors affect the financial condition of the Commonwealth,  including
many  social,  environmental,  and  economic  conditions,  which are  beyond the
control of the Commonwealth. As with most urban states, the continuation of many
of the Commonwealth's programs,  particularly its human service programs, is, in
significant part,  dependent upon continuing federal  reimbursements  which have
been declining.


                        KEYSTONE NEW YORK TAX FREE FUND

GENERAL

     During the 1980's,  New York's  economy  underperformed  the nation's.  The
State's  economic  performance was reflected in a contracting  economic base and
dwindling  economic  growth that resulted in an erosion of the State's  relative
economic  influence.  A review of the decade's  employment trends indicates that
the State  consistently  lagged the nation in employment  growth. In contrast to
the State's  relative  underperformance,  New York City's economy grew steadily.
Economic  growth was  attributed to a 14.4%  overall  employment  increase.  The
service  sector  increased  3.5% per year and the finance and real estate sector
experienced an annual 2.9% increase. The bull markets of the 1980s gave powerful
economic  impetus  to the  financial  sector.  The  boom in the  finance  sector
aggravated  local  inflationary  pressure.  Between  1980 and  1989  the  City's
consumer  price index  increased  4.6% per year versus a 3.6%  increase  for the
nation  and  overall  wage  rates  climbed  7.1%  per  year,  approximately  3.5
percentage points above the U.S. rate. The 1987 stock market crash was a turning
point in the City's  economic  direction.  The ripple  effect of the  post-crash
layoffs in the finance, insurance and real estate sectors resulted in a stagnant
city economy.

     The New York economy was  severely  impacted by the  recession,  but it has
begun to show signs of recovery.  The recession has been more severe in New York
than in other parts of the nation,  owning to a significant  retrenchment in the
financial services industry, cutbacks in defense spending, and an overbuilt real
estate  market.   More  than  564,000  jobs  were  lost  during  the  recession,
representing 7% of the pre-recession  base. During 1993 employment  continued to
decline but at  diminishing  rates (a 0.3% decline  during  1993),  indicating a
stabilizing  economy.  A modest job growth of approximately  0.8% is anticipated
for 1994.  Through  the year 1988 New York's  employment  growth is  expected to
average  approximately  1.4% per year,  compared  to the 2.3%  annual  expansion
experienced  during  1983-1988.  It is  anticipated  that New York's service and
trade  sectors  will  be the  major  contributors  to  this  growth,  while  the
manufacturing sector is expected to continue to contract. The State's economy is
significantly  affected by New York City's  economy by virtue of New York City's
dominance  in  population  and  economic  activity.  New York City  accounts for
approximately 41% of the State's population and personal income.

     The  revised  1993-1994  State  Financial  Plan  is  based  on an  economic
projection  that New York will  perform  more poorly than the nation as a whole.
Real gross  domestic  product grew  modestly  during  calendar  year 1992 and is
expected to show increased growth in calendar 1993. Many uncertainties  exist in
forecasts  of the State's  economy,  which  could have an adverse  effect on the
State,  and there can be no assurance that the State economy will not experience
worse-than-predicted  results  in  the  1994  fiscal  year,  with  corresponding
material  and  adverse  effects  on the  State's  projections  of  receipts  and
disbursements.

     For fiscal 1993, State financial operations produced a $671 million surplus
on a general fund budget of nearly $31 billion. This surplus followed four years
of operating  deficits.  The accumulated  general fund deficit peaked in 1991 at
$6.2  billion and has since  decreased  to $2.6  billion for fiscal  1993.  Debt
reform is the principal cause for this improvement. Short-term borrowing is only
$850 million for the current fiscal year, the lowest level since 1969. To reduce
borrowing  costs  and  improve  market  access,  the  Governor  is  proposing  a
constitutional  amendment to limit issuance of appropriation bonds and to create
tax-backed debt.

     The State's updated  financial plan estimates that fiscal 1994 will achieve
an  ending  cash  balance  of  approximately  $299  million.  This  larger  than
anticipated  surplus  is  a  result  of a  stabilizing  economy,  improving  tax
collections  and slowing  expenditure  growth.  The 1993 and 1994  budgets  were
enacted  in a timely  manner  and were based on  realistic  economic  forecasts,
conservative  revenue  assumptions and some spending  restraint.  The Governor's
proposed  budget for fiscal 1995  provides for general fund  spending  growth of
4.3%,  use of the  current  year  surplus,  modest tax cuts and a small level of
non-recurring  measures.  The fiscal 1995 budget  relies on modest growth of the
economy and includes growth in personal income withholding and sales and use tax
receipts of 5.3% and 4.1%, respectively.

     Significant  litigation  exists at the State  level of  government.  A suit
filed  by  a  taxpayer  activist   challenges  the   constitutionality   of  the
transportation  financing  plan.  Also, in November  1993,  the Court of Appeals
affirmed a lower court's  decision,  declaring that certain  accounting  changes
made in funding methods of the State  retirement  system were  unconstitutional.
The State may also be liable for significant  payments related to a U.S. Supreme
Court decision involving abandoned property.

STATE FINANCING ACTIVITIES

     For the four fiscal  years prior to fiscal  year 1992,  the State  incurred
operating  deficits in the general  fund.  In fiscal  1993,  the State began the
process  of  financial  reform.   Based  upon  realistic  economic  and  revenue
estimates,  the fiscal year 1993 financial plan exceeded expectations and closed
the year with a general  fund  operating  surplus of $671 million in the General
Fund. The surplus  revenues were  deposited  into a tax refund reserve  account,
which typically had been funded in the  $300-$350 million range.  Overfunding of
this reserve allows some additional fiscal  flexibility which was not present in
recent prior State budgets.

     New York, for the second  consecutive  year,  passed its fiscal 1994 budget
essentially  on time.  The State faced a $3.7 billion budget gap for fiscal year
1994,  as  determined  by  baseline  projections.  The  Governor's  1994  budget
addressed  this gap by reducing  expenditures  by $1.6  billion  and  increasing
revenues  by $2.1  billion.  The  budget  is based  upon  conservative  economic
assumptions,  which fall  below  those  forecasted  by the  leading  independent
forecasters.

     During the past  several  years,  the State has been  forced to borrow on a
seasonal  basis  due to cash  flow  timing  problems.  In June  1990,  the Local
Government  Assistance  Corporation  ("LGAC")  was  formed  as a public  benefit
corporation  for the  purpose  of  issuing  long term  obligations  designed  to
eliminate this need. The  legislation  which created the LGAC specified that the
obligations  will be amortized over no more than 30 years and put a $4.7 billion
cap, net of LGAC proceeds,  on the seasonal borrowing  program.  This cap may be
exceeded in cases where the Governor and the legislature have certified the need
for  additional  borrowing and have devised a method for reducing it back to the
cap no later than the fourth  fiscal year after the limit is  exceeded.  If this
cap were to be exceeded,  it could result in action by the rating agencies which
could  adversely  affect  prices of bonds  held by the Fund.  To date,  LGAC has
issued  its  bonds to  provide  net  proceeds  of  $3.281  billion  and has been
authorized  to issue its bonds to provide net  proceeds  of up to an  additional
$703 million during the State's 1994 fiscal year.

     In April 1993,  legislation  was also  enacted  providing  for  significant
changes in the long term financing  practices of the State and the  Authorities.
The Legislature passed a proposed constitutional amendment that would permit the
State,  without a voter  referendum,  but within a  formula-based  cap, to issue
revenue  bonds,  which would be debt of the State secured  solely by a pledge of
certain State tax receipts  (including  those allocated to State funds dedicated
for transportation  purposes) and not by the full faith and credit of the State.
In addition,  the proposed  amendment  would require that State debt be incurred
only for capital projects  included in a multi-year  capital  financing plan and
would prohibit  lease-purchase and contractual  obligation  financing mechanisms
for State  facilities.  The Governor and the Legislative  leaders have indicated
that public  hearings  will be held on the  proposed  constitutional  amendment.
Before becoming effective,  the proposed constitutional  amendment must first be
passed again by the next  separately-elected  Legislature  and then  approved by
voters at a general election,  so that it could not become effective until after
the general election in November 1995.

THE CITY OF NEW YORK

     The fiscal  health of the State is closely  related to the fiscal health of
its  localities,  particularly  the City of New  York,  which has  required  and
continues to require significant financial assistance from the State. During the
1990 and 1991 fiscal  years,  the City  experienced  significant  shortfalls  in
almost all of its major tax sources and increases in social service  costs,  and
has been required to take actions to close  substantial  budget gaps in order to
maintain  balanced  budgets in accordance  with its financial  plan.  For fiscal
1993, the City achieved balanced operating results.

     In response to the City's financial crisis in 1975, the State took a number
of steps to assist  the City in  returning  to  fiscal  stability.  Among  these
actions, the State created the Municipal Assistance  Corporation for the City of
New York ("MAC") to provide  financing  assistance  to the City.  The State also
enacted the New York State Financial Emergency Act for the City of New York (the
"Financial  Emergency Act") which, among other things,  established the New York
State  Financial  Control  Board (the  "Control  Board")  to oversee  the City's
financial  affairs.  The State also  established  the Office of the State Deputy
Comptroller  for New York  ("OSDC")  in the Office of the State  Comptroller  to
assist the Control Board in exercising its powers and responsibilities.

     The City  operates  under a four  year  Financial  Plan  which is  prepared
annually and is  periodically  updated.  On June 30, 1986,  the Control  Board's
powers of approval over the City's Financial Plan were suspended pursuant to the
Financial  Emergency Act.  However,  the Control Board, MAC and OSDC continue to
exercise various monitoring functions relating to the City's financial position.
The City  submits its  financial  plans as well as the  periodic  updates to the
Control Board for its review.  In August 1993, the City submitted to the Control
Board its  1994-1997  Financial  Plan.  The  Financial  Plan projects a balanced
budget in fiscal 1994,  based on revenues of approximately  31.250 billion.  The
Financial Plan also predicts budget gaps of approximately $1.3 billion in fiscal
year 1995,  $1.8  billion in fiscal  year 1996 and $2.0  billion in fiscal  year
1997.

     Estimates  of the City's  revenues and  expenditures  are based on numerous
assumptions  and are subject to various  uncertainties.  If expected  federal or
State  aid  are not  forthcoming,  if  unforeseen  developments  in the  economy
significantly  reduce  revenues  derived from  economically  sensitive  taxes or
necessitate  increased  expenditures for public  assistance,  if the City should
negotiate wage increases for its employees greater than the amounts provided for
in the City's Financial Plan or if other  uncertainties  materialize that reduce
expected revenues or increase projected  expenditures,  then, to avoid operating
deficits,  the City may be required to implement  additional actions,  including
increases in taxes and  reductions in essential  City  services.  The City might
also seek additional assistance from the State.

AUTHORITIES

`New  York  State's   authorities  are  generally   responsible  for  financing,
constructing and operating  revenue-producing  public benefit facilities.  As of
September 30, 1992,  there were 18 Authorities that had outstanding debt of $100
million or more. The aggregate  outstanding debt,  including refunding bonds, of
these 18  Authorities  was $62.2  billion as of  September  30,  1992,  of which
approximately  $8.2 billion was moral  obligation debt and  approximately  $17.1
billion was financed under  lease-purchase or  contractual-obligation  financing
arrangements.  While Authorities are generally  supported by revenues generated,
financed or operated by projects of the Authorities,  in recent years, the State
has provided  financial  assistance  through  appropriations  to enable  certain
Authorities (in particular, the New York State Urban Development Corporation and
the New York State Housing Finance Agency) to meet their financial  obligations.
Further  assistance to these  Authorities is expected to be required to continue
in the future.

     The  Metropolitan   Transportation   Authority  (the  "MTA")  oversees  the
operation of New York City's bus and subway systems and,  through its affiliates
and  subsidiaries,  operates  certain  commuter  rail and bus  lines and a rapid
transit line.  Through an affiliate,  the MTA operates  certain  intrastate toll
bridges  and  tunnels.  The MTA has  depended  and will  continue to depend upon
Federal,  State, local government and agency support to operate the mass transit
portion of these operations because fare revenues are insufficient.  The MTA and
the commuter  railroads ended their 1991 fiscal year with their budgets balanced
on a cash basis. For 1993, a $69.8 million cash surplus has been projected.  The
1994 operating budget proposal projects a $66 million cash surplus.

     In 1981 the Legislature  authorized  procedures for the adoption,  approval
and amendment of a five year plan for a capital program  designed to upgrade the
performance of the MTA's transportation  systems and to supplement,  replace and
rehabilitate  facilities  and  equipment,  and also granted  certain  additional
bonding  authorization  for the capital  program.  The MTA has  submitted to the
State several 1992-96 Capital Program proposals which have been rejected.  A one
year  program of  approximately  $1.6  billion has been  deemed  approved in the
interim.

AGENCIES AND LOCALITIES

     Certain  localities  in  addition  to New York City  could  have  financial
problems leading to requests for additional State assistance  during the State's
1993-1994 fiscal year and thereafter.  The potential impact on the State of such
requests by localities is not included in the  projections of the State receipts
and disbursements in the State's 1993-1994 fiscal year.

     Fiscal difficulties experienced by the City of Yonkers ("Yonkers") resulted
in the  creation  of the  Financial  Control  Board of the City of Yonkers  (the
"Yonkers  Board")  by the  State in 1984.  The  Yonkers  Board is  charged  with
oversight of the fiscal affairs of Yonkers. Future actions taken by the Governor
or the State  Legislature  to assist Yonkers could result in allocation of State
resources in amounts that cannot yet be determined.

     Municipalities  and school districts have engaged in substantial short term
and long term  borrowing.  In 1991, the total  indebtedness of all localities in
the State was  approximately  $32.2 billion,  of which $16.8 billion was debt of
New York City (excluding $6.7 billion in Municipal Assistance Corporation debt);
a small portion of this indebtedness  represented borrowing to finance budgetary
deficits  and was issued  pursuant  to  enabling  State  legislation.  State law
requires  the  Comptroller  to review and make  recommendations  concerning  the
budgets of these local  government  units other than New York City authorized by
State law to finance  deficits during the period that such deficit  financing is
outstanding.   Fifteen  localities  had  outstanding  indebtedness  for  deficit
financing at the close of their fiscal years ending 1991.  In 1992, an unusually
large  number of local  government  units  requested  authorization  for deficit
financing.  According  to the  Comptroller,  ten local  governmental  units were
authorized to issue deficit financing in the aggregate amount of $131.1 million,
including  Nassau  County for $65 million in six-year  deficit bonds and Suffolk
County for $36 million in  six-year  deficit  bonds.  Certain  proposed  federal
expenditure reductions would reduce, or in some cases eliminate, federal funding
of some local  programs  and  accordingly  might  impose  substantial  increased
expenditure requirements on affected localities.  If the State, New York City or
any  of  the  Authorities   were  to  suffer  serious   financial   difficulties
jeopardizing  their  respective  access  to  the  public  credit  markets,   the
marketability of notes and bonds issued by localities  within the State could be
adversely  affected.  Localities also face  anticipated  and potential  problems
resulting from certain pending litigation,  judicial  decisions,  and long range
economic  trends.   The  longer  range  potential  problems  of  declining  city
population,  increasing  expenditures  and other economic trends could adversely
affect localities and require increasing State assistance in the future.

LITIGATION

     Certain  litigation  pending against the State or its officers or employees
could have a substantial  long term adverse effect on State finances.  Among the
more  significant  of these cases are those that  involve:  (1) the  validity of
agreements and treaties by which various Indian tribes  transferred title to the
state of certain  land in central and upstate New York;  (2) certain  aspects of
the State's  Medicaid rates and regulations;  (3) treatment  provided at several
state mental  health  facilities;  (4)  contamination  in the Love Canal area of
Niagara  Falls;  (5)  alleged  responsibility  of State  officials  to assist in
remedying  racial  segregation  in the City of Yonkers;  and (6)  challenges  to
certain public authority financial programs.

     Adverse  developments  in  those  proceedings  or  the  initiation  of  new
proceedings  could  affect  the  ability  of the State to  maintain  a  balanced
1993-1994 State  Financial  Plan. An adverse  decision in any of the above cited
proceedings  could exceed the amount of the Revised  1993-1994  State  Financial
Plan  reserve for the payment of  judgments  and,  therefore,  could  affect the
ability of the State to maintain a balanced 1993-1994 State Financial Plan.


                      KEYSTONE PENNSYLVANIA TAX FREE FUND

GENERAL

   
     The   Commonwealth  of   Pennsylvania,   the  fifth  most  populous  state,
historically  has been  identified  as a heavy  industry  state,  although  that
reputation  has  changed  with the  decline  of the  coal,  steel  and  railroad
industries and the resulting  diversification of the  Commonwealth's  industrial
composition.  The  major  new  sources  of  growth  are in the  service  sector,
including  trade,  medical  and  health  services,   educational  and  financial
institutions. Manufacturing has fallen behind in both the service sector and the
trade sector as a source of employment in Pennsylvania.  The Commonwealth is the
home  for  more  than  268,600  businesses  and the  headquarters  for 64  major
corporations.  Pennsylvania's  average  annual  unemployment  rate for the years
1988,  1989 and  1990  remained  slightly  below  the  nation's  annual  average
unemployment rate, and Pennsylvania's  average annual  unemployment rate for the
years 1991,  1992 and 1993 remained  slightly above the nation's  annual average
unemployment  rate. The unadjusted  unemployment  rate for both Pennsylvania and
the United States for April,  1995 was 5.8%.  The  population  of  Pennsylvania,
12,026  million  people in 1994  according  to the U.S.  Bureau  of the  Census,
represents  an increase  from the 1985  estimate of 11,772  million.  Per capita
income in Pennsylvania for 1993 of $20,352 was higher than the per capita income
of the United States of $20,817. The Commonwealth's General Fund, which receives
all tax receipts and most other  revenues and through  which debt service on all
general obligations of the Commonwealth are made, closed fiscal years ended June
30,  1991,  June 30,  1992 and June 30,  1993 with  fund  balances  of  negative
$980,936, positive $87,455 and positive $698,945, respectively.
    

DEBT

   
     The Commonwealth may incur debt to rehabilitate areas affected by disaster,
debt approved by the electorate, debt for certain capital projects (for projects
such as highways, public improvements, transportation assistance, flood control,
redevelopment  assistance,  site development and industrial development) and tax
anticipation  debt payable in the fiscal year of issuance.  The Commonwealth had
outstanding  general  obligation  debt of $5,075  million at June 30, 1994.  The
Commonwealth  is not  permitted to fund deficits  between  fiscal years with any
form of debt. All year-end deficit balances must be funded within the succeeding
fiscal year's budget. At November 29, 1994, all outstanding  general  obligation
bonds of the  Commonwealth  were rated AA- by Standard & Poor's  Corporation and
A-1 by  Moody's  Investors  Service,  Inc.  (see  Appendix  B).  There can be no
assurance  that these  ratings  will  remain in effect in the  future.  Over the
five-year  period ending June 30, 1999, the  Commonwealth  has projected that it
will issue notes and bonds totaling $2,293 million and retire bonded debt in the
principal amount of $2,448 million.

     Certain agencies created by the Commonwealth  have statutory  authorization
to incur debt for which Commonwealth  appropriations to pay debt service thereon
are not required. As of June 30, 1994, total combined debt outstanding for these
agencies was $5,995  million.  The debt of these agencies is supported by assets
of, or revenues  derived  from,  the  various  projects  financed  and is not an
obligation of the Commonwealth.  Some of these agencies, however, are indirectly
dependent on Commonwealth  appropriations.  The only  obligations of agencies in
the  Commonwealth  that bear a moral  obligation of the  Commonwealth  are those
issued by the  Pennsylvania  Housing  Finance Agency  ("PHFA"),  a state-created
agency which provides  housing for lower and moderate income  families,  and The
Hospitals  and  Higher  Education  Facilities  Authority  of  Philadelphia  (the
"Hospital Authority"),  an agency created by the City of Philadelphia to acquire
and  prepare  various  sites for use as  intermediate  care  facilities  for the
mentally retarded.
    

LOCAL GOVERNMENT DEBT

     Numerous local  government units in Pennsylvania  issue general  obligation
(i.e.,  backed by taxing  power) debt,  including  counties,  cities,  boroughs,
townships  and school  districts.  School  district  obligations  are  supported
indirectly by the Commonwealth. The issuance of non-electoral general obligation
debt is limited by  constitutional  and statutory  provisions.  Electoral  debt,
i.e., that approved by the voters, is unlimited.  In addition,  local government
units and municipal and other authorities may issue revenue obligations that are
supported by the revenues  generated from  particular  projects or  enterprises.
Examples include  municipal  authorities  (frequently  operating water and sewer
systems),   municipal  authorities  formed  to  issue  obligations   benefitting
hospitals and educational institutions,  and industrial development authorities,
whose obligations  benefit  industrial or commercial  occupants.  In some cases,
sewer or water revenue  obligations are guaranteed by taxing bodies and have the
credit characteristics of general obligations debt.

OTHER FACTORS

     The  performance  of  the  obligations  held  by  the  Fund  issued  by the
Commonwealth, its agencies,  subdivisions and instrumentalities are in part tied
to state-wide,  regional and local conditions within the Commonwealth and to the
creditworthiness of certain  non-Commonwealth  related obligors,  depending upon
the Pennsylvania  Fund's portfolio mix at any given time. Adverse changes to the
state-wide,  regional or local  economies or changes in government may adversely
affect   the   creditworthiness   of  the   Commonwealth,   its   agencies   and
municipalities,   and  certain   other   non-government   related   obligors  of
Pennsylvania tax-free obligations (e.g., a university, a hospital or a corporate
obligor).  The City of Philadelphia,  for example,  experienced severe financial
problems which  impaired its ability to borrow money and adversely  affected the
ratings of its obligations and their marketability. Conversely, some obligations
held by the Fund will be almost exclusively dependent on the creditworthiness of
one  underlying  obligor,  such as a project  occupant  or provider of credit or
liquidity support.


                          KEYSTONE TEXAS TAX FREE FUND

GENERAL

   
     The collapse of oil prices in the  mid-1980s  adversely  affected the Texas
economy due to the State's heavy  dependence on oil production.  The economy has
become more stable due to the  decreased  role of the oil and gas  industry  and
increased  diversification  into other  employment  sectors  such as the service
producing  sectors,  including  transportation  and public  utilities,  finance,
insurance, real estate, services, trade and government,  which are currently the
major sources of job growth in Texas.  Unlike the rest of the U.S., in Texas the
manufacturing  and  construction  industries  are growing  nearly as fast as the
service-producing  sector.  Construction  was the State's  fastest growing major
industry   through  1994.   Based  on  information  from  the  Texas  Employment
Commission,  non-farm  employment  in Texas has reached an all-time high of 7.82
million. Texas' jobless rate was 6.4% in 1994, compared to a national average of
6.1%.

     The  Comptroller of Public Accounts of the State of Texas predicts that the
overall Texas economy will out-pace national economic growth in the long term by
an annual average of more than one-half  percentage point. Of course,  there can
be no assurances  that this forecast will be realized.  Moreover,  even if it is
realized,  the State's economic  performance as a whole would not necessarily be
indicative  of the  financial  performance  of the  State or local  governments,
especially  in regions of the State which do not perform as well as the State as
a whole.

STATE GOVERNMENT REVENUES

     The state  government  ended  each of the past six  fiscal  years with cash
surpluses.  At the end of  fiscal  1994,  the State  had a $2,225  million  cash
balance in the general  revenue  fund,  as compared  with a $1,693  million cash
balance at the end of fiscal 1993.

     Historically,  the primary sources of the state government's  revenues have
been sales taxes,  mineral  severance taxes and federal  grants.  Federal grants
were the State's main revenue  source,  accounting  for 28.7% of state  revenues
during fiscal 1994,  while sales tax accounted for 26.7% of state revenue during
fiscal  1994.  The  remainder  of the State  government's  revenues  are derived
primarily from the motor fuels tax and other excise taxes, licenses, fees, fines
and  penalties,   and  interest  and  investment  income.   Much  of  the  State
government's  revenues  are special  revenues  which are  dedicated by the State
constitution or statute to specific  purposes which may be inconsistent with the
payment of debt service on State obligations.  In addition, the State government
manages two important trust funds--the  Permanent  University Fund and Permanent
School  Fund--endowed  with  proceeds  of the sale or lease of  dedicated  State
lands,  including mineral interests,  the income from which is  constitutionally
dedicated to the support of State  universities and public primary and secondary
schools, respectively.
    

     The State  constitution  prohibits  the State  government  from  levying ad
valorem taxes on property for general revenue purposes.  The State  constitution
also limits the rate of growth of appropriations from tax revenues not dedicated
by the constitution  during any biennium to the estimated rate of growth for the
State's economy.  The Legislature may avoid the constitutional  limitation if it
finds, by a majority vote of both houses,  that an emergency  exists.  The State
constitution authorizes the Legislature to provide by law for the implementation
of this restriction,  and the Legislature,  pursuant to such authorization,  has
defined  the  estimated  rate of  growth  in the  State's  economy  to mean  the
estimated increase in State personal income.

STATE GOVERNMENT DEBT

     With certain exceptions,  the Constitution generally prohibits the creation
of debt by or for the State. The limitations of the Constitution do not prohibit
the  issuance of revenue  bonds,  since the Texas  courts have held that certain
obligations which are not payable from tax sources do not create a "debt" within
the meaning of the  Constitution.  The State and  various  state  agencies  have
issued revenue bonds payable from the revenues  produced by various  facilities.
Furthermore,  obligations  which are payable from funds expected to be available
during the current budget period do not constitute  "debt" within the meaning of
the Constitution.  Short term obligations,  such as tax and revenue anticipation
notes which the  Treasurer  is  authorized  to issue  solely to  coordinate  the
State's  cash flow  within a fiscal  year,  and which must mature and be paid in
full during the  biennium in which they were  issued,  are not deemed to be debt
within  the  meaning  of the  constitutional  prohibition.  In  addition,  State
agencies may issue  revenue  bonds payable from payments to be made by the State
government for a lease or purchase of financed  facilities,  subject to biennial
appropriations.  These bonds are  considered  "moral  obligations"  of the State
government,  since failure to appropriate  funds could injure the State's credit
in the marketplace, although the State government is not legally obligated to do
so.

   
     At times, the voters of Texas, by constitutional amendment, have authorized
the issuance of debt by the State,  including general obligation bonds backed by
the full  faith and  credit of the  State.  In some  cases the  authorized  debt
requires the approval of the Legislature, but in other cases, the constitutional
amendments permit the debt to be issued without specific  legislative action. Of
the general  obligation  bonds authorized by the State's voters through November
30, 1994, $4.5 billion then remained outstanding and an additional $3.86 billion
were yet to be  issued.  These  bonds  include  bonds  that may be issued by the
Veterans'  Land Board for  veterans  to  purchase  land and  housing,  the Water
Development Board for conservation and development of water resources, the Parks
and Wildlife  Department for  acquisition  and  development of state parks,  the
Texas  Higher  Education  Coordinating  Board  to  finance  student  loans,  the
Department of Agriculture for the purchase of farm and ranch real estate,and the
Texas Public Finance Authority to finance,  repair and construct facilities such
as  corrections  and mental health  institutions.  In addition,  the voters have
authorized  the  respective  Boards of Regents of the University of Texas System
and the Texas A&M University  System to issue bonds payable from income from the
Permanent  University  Fund  up to 30%  of  the  book  value  of  the  Permanent
University  Fund,  exclusive of real estate at the time of issuance.  The voters
have also authorized the appropriation of the first $100 million coming into the
State Treasury, and not otherwise appropriated by the Constitution,  to pay debt
service on bonds issued by other state colleges and universities in the State.
    

LOCAL GOVERNMENT REVENUES

     Various  state laws place limits upon the amounts of tax that can be levied
upon the property subject to ad valorem taxes within various taxing units,  such
as cities, counties and districts which have ad valorem taxing powers (including
without limitation, school and hospital districts). Because ad valorem taxes are
computed upon the appraised  property  valuations  and property  appraisals  are
required to be conducted only every three years,  it may be several years before
any  decline  in  property   values  will  be  reflected  in  decreases  in  tax
collections.  Conversely,  there  may be a  similar  lag  time  before a rise in
property values results in increased ad valorem tax collections.

FUNDING OF PUBLIC EDUCATION

   
     On May 31, 1993,  the Texas  governor  signed a  comprehensive  legislative
revision to the school  finance  provisions  of the Texas  Education  Code.  The
legislative revision resulted from a series of court decisions commonly referred
to as Edgewood v. Kirby, in which Texas courts declared the Texas school finance
system  unconstitutional  under Texas law.  Generally,  the courts  declared the
school finance system unconstitutional because there must be a "direct and close
correlation  between a  district's  tax  effort  and the  educational  resources
available to it," and because districts must have "substantially equal access to
similar revenues per pupil at similar levels of tax effort."

     The Texas  school  finance  system is funded  from a  combination  of local
school  district ad valorem  taxes,  State funds from the Permanent  School Fund
endowment and certain designated tax revenues,  and state  appropriation.  "Tier
one" funding  guarantees a school  district a basic  allotment per pupil;  "tier
two"  funding  guarantees  a school  district a certain  amount of  "enrichment"
revenue  per  student to the extent the local  school  district  sets a tax rate
above $0.86 per $100 assessed valuation.

     As under prior law, the legislative  revision  retains a two tier system of
finance.  Under the  legislative  revision,  if a  district's  adjusted  taxable
property wealth per student exceeds $280,000,  the district must exercise one of
five operations to reduce its wealth per student to that level:  consolidate the
district  with a  property-poor  district  for  all  purposes;  consolidate  the
district  with a  property-poor  district  solely for  purposes  of levying  and
distributing  either  maintenance,  taxes or both  maintenance  and debt service
taxes;  detach  property  from the district for  annexation  by a  property-poor
district;  purchase an attendance credit by paying tax revenues to the State for
redistribution to property-poor  districts; or contract to educate students in a
property-poor district at the wealthy district's expense. If a district fails to
exercise a permitted option,  the Commissioner of Education must detach mineral,
utility,  industrial,  or  commercial  property  from the district and annex the
property to a property-poor district or, if necessary,  consolidate the district
with a property-poor district.

     On January 30, 1995,  the Texas  Supreme  Court ruled that the  legislative
revision is constitutional in all respects. It suggested,  however, that further
changes may be needed in the near future to provide  equal access to funding for
capital projects as well as for operations.  The Texas  Legislature is currently
considering  legislation  which  attempts  to  provide  such  equalization.  The
legislative  revision and future  efforts to equalize  school funding may affect
the financial  condition of the Texas State  Government and certain Texas school
districts.
    

     Public higher  education in the State is funded  through a  combination  of
tuition,  student fees and other local funds (including gifts from benefactors),
income  from  the  Permanent  University  Fund  and  appropriations  made by the
Legislature.  Tuition rates are set by the Legislature, except that institutions
may double the tuition rate for graduate students.  Many student fees are set by
the boards of regents of the various colleges and universities.

OTHER FACTORS

   
     The Texas Fund  expects to invest its assets in general  obligation  bonds,
moral  obligation  bonds,  and  revenue  bonds  issued  by the  State  and local
governments  to  finance  their own  works or to  finance  private  enterprises.
Payment of the revenue  bonds will depend on the  financial  performance  of the
enterprises  financed,  which may include  public  water,  sewer,  and  electric
utility  systems,   municipal  airports,   nonprofit   hospitals,   multi-family
residential  housing  developments,  portfolios  of  single-family  mortgages or
student loans, and other  enterprises.  The performance of these enterprises may
be  affected  by  industry  trends,  competition,  labor  relations,  prevailing
interest  rates,  and similar  factors which cannot be predicted with certainty.
Payment of  general  and moral  obligation  bonds  will  depend  upon the future
financial  condition  of the issuing  governments  and their other  obligations,
including   obligations   concerning   public  education,   criminal   detention
facilities, and other matters which have been or hereafter may be imposed by the
courts. The financial  performance of financed enterprises and local governments
could be adversely affected not only by any downturn in the State's economy as a
whole, but also by regional or local factors such as closings of military bases,
any layoffs by large employers.

                      CORPORATE AND MUNICIPAL BOND RATINGS

S&P CORPORATE AND MUNICIPAL BOND RATINGS

A.       MUNICIPAL NOTES

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

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

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

         Note ratings are as follows:

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

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

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

B.       TAX EXEMPT DEMAND BONDS

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

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

C.       CORPORATE AND MUNICIPAL BOND RATINGS

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

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

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

         b. Nature of and provisions of the obligation; and

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

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

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

C.       BOND RATINGS ARE AS FOLLOWS:

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

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

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

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

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

D.       MOODY'S CORPORATE AND MUNICIPAL BOND RATINGS

         Moody's ratings are as follows:

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

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

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

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

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

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

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

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

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


                            MONEY MARKET INSTRUMENTS

         Money market  securities are instruments  with remaining  maturities of
one year or less such as bank  certificates  of deposit,  bankers'  acceptances,
commercial paper (including  variable rate master demand notes), and obligations
issued or guaranteed by the U.S. government,  its agencies or instrumentalities,
some of which may be subject to repurchase agreements.

COMMERCIAL PAPER

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

A.       S&P RATINGS

         An  S&P  commercial  paper  rating  is  a  current  assessment  of  the
likelihood of timely payment of debt having an original maturity of no more than
365 days.  Ratings are graded  into four  categories,  ranging  from "A" for the
highest  quality  obligations  to "D" for the  lowest.  The top  category  is as
follows:

         1. A: Issues  assigned  this highest  rating are regarded as having the
greatest  capacity for timely  payment.  Issues in this category are  delineated
with the numbers 1, 2 and 3 to indicate the relative degree of safety.

         2. A-1: This designation  indicates that the degree of safety regarding
timely payment is either overwhelming or very strong. Those issues determined to
possess  overwhelming  safety  characteristics  are denoted with a plus (+) sign
designation.

B.       MOODY'S RATINGS

         The  term  "commercial  paper"  as used  by  Moody's  means  promissory
obligations  not having an original  maturity in excess of nine months.  Moody's
commercial  paper  ratings  are  opinions  of the  ability  of  issuers to repay
punctually  promissory  obligations not having an original maturity in excess of
nine months. Moody's employs the following designation,  judged to be investment
grade, to indicate the relative repayment capacity of rated issuers.

         1. The rating PRIME-1 is the highest  commercial  paper rating assigned
by Moody's.  Issuers  rated  PRIME-1 (or related  supporting  institutions)  are
deemed to have a  superior  capacity  for  repayment  of short  term  promissory
obligations.  Repayment capacity of Prime-1 issuers is normally evidenced by the
following characteristics:

         1)       leading market positions in well-established industries;
         2)       high rates of return on funds employed;

         3)       conservative  capitalization structures with moderate reliance
                  on debt and ample asset protection;

         4)       broad margins in earnings  coverage of fixed financial charges
                  and high internal cash generation; and

         5)       well  established  access to a range of financial  markets and
                  assured sources of alternate liquidity.

         In assigning  ratings to issuers whose commercial paper obligations are
supported by the credit of another  entity or entities,  Moody's  evaluates  the
financial strength of the affiliated  corporations,  commercial banks, insurance
companies,  foreign governments or other entities, but only as one factor in the
total rating assessment.

CERTIFICATES OF DEPOSIT

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

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

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

BANKERS' ACCEPTANCES

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

U.S. GOVERNMENT SECURITIES

         Securities  issued  or  guaranteed  by the U.S.  government  include  a
variety  of  Treasury  securities  that  differ  only in their  interest  rates,
maturities  and  dates of  issuance  and  securities  issued  by the  Government
National Mortgage Association (GNMA). Treasury bills have maturities of one year
or less.  Treasury notes have  maturities of one to ten years and Treasury bonds
generally  have  maturities  of greater  than ten years at the date of issuance.
GNMA securities include GNMA mortgage pass-through certificates. Such securities
are supported by the full faith and credit of the U.S.

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

         Some  obligations of U.S.  government  agencies and  instrumentalities,
such as securities of Federal Home Loan Banks, are supported by the right of the
issuer to borrow from the Treasury.  Others, such as bonds issued by the Federal
National Mortgage Association, a private corporation,  are supported only by the
credit of the  instrumentality.  Because the U.S. government is not obligated by
law to provide support to an instrumentality it sponsors,  a Fund will invest in
the securities issued by such an instrumentality  only when Keystone  determines
under  standards  established by the Board of Trustees that the credit risk with
respect  to  the  instrumentality  does  not  make  its  securities   unsuitable
investments. U.S. government securities do not include international agencies or
instrumentalities   in   which   the   U.S.   government,    its   agencies   or
instrumentalities participate, such as the World Bank, Asian Development Bank or
the  Inter-American  Development  Bank, or issues insured by the Federal Deposit
Insurance Corporation.

MUNICIPAL LEASE OBLIGATIONS

         Municipal lease obligations purchased primarily through Certificates of
Participation  ("CPO's") are used by state and local  governments to finance the
purchase of property,  and function much like installment purchase  obligations.
The payments made by the municipality under the lease are used to repay interest
and  principal on the bonds issued to purchase  the  property.  Once these lease
payments are completed,  the municipality  gains ownership of the property for a
nominal sum. The lessor is, in effect,  a lender  secured by the property  being
leased. A feature which distinguishes CPOs from municipal debt is that the lease
which is the subject of the  transaction  must contain a  "nonappropriation"  or
"abatement" clause. A nonappropriation clause provides that provides that, while
the  municipality  will  use its  best  efforts  to  make  lease  payments,  the
municipality  may  terminate  the lease  without  penalty if the  municipality's
appropriating body does not allocate the necessary funds. Local administrations,
being faced with increasingly  tight budgets,  therefore have more discretion to
curtail  payments under COPs than they do to curtail  payments on  traditionally
funded  debt  obligations.   If  the  government  lessee  does  not  appropriate
sufficient  monies to make lease payments,  the lessor or its agent is typically
entitled to repossess the property.  In most cases,  however, the private sector
value of the  property  will be less than the amount the  government  lessee was
paying.

         Criteria  considered  by the rating  agencies and Keystone in assessing
the risk of  appropriation  include the issuing  municipality's  credit  rating,
evaluation of how essential the leased property is to the  municipality and term
of the lease  compared to the useful life of the leased  property.  The Board of
Trustees  reviews  the COPs held in each  Fund's  portfolio  to assure that they
constitute liquid  investments based on various factors reviewed by Keystone and
monitored  by the Board.  Such  factors  include (a) the credit  quality of such
securities  and the extent to which they are rated or, if  unrated,  comply with
existing  criteria  and  procedures  followed to ensure that they are of quality
comparable  to the ratings  required  for each Fund's  investment,  including an
assessment of the likelihood that the leases will not be cancelled; (b) the size
of the municipal  securities  market,  both in general and with respect to COPs;
and (c) the extent to which the type of COPs held by each Fund trade on the same
basis and with the same degree of dealer  participation as other municipal bonds
of comparable credit rating or quality.


               FUTURES CONTRACTS AND RELATED OPTIONS TRANSACTIONS

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

         For example,  when a Fund  anticipates a  significant  market or market
sector  advance,  it will  purchase a stock  index  futures  contract as a hedge
against  not  participating  in such  advance at a time when a Fund is not fully
invested.  The purchase of a futures  contract serves as a temporary  substitute
for the  purchase of  individual  securities  which may then be  purchased in an
orderly fashion. As such purchases are made, an equivalent amount of index based
futures contracts would be terminated by offsetting  sales. In contrast,  a Fund
would sell stock index  futures  contracts  in  anticipation  of or in a general
market or market sector  decline that may  adversely  affect the market value of
the Fund's  portfolio.  To the extent that the Fund's portfolio changes in value
in correlation with a given index,  the sale of futures  contracts on that index
would  substantially  reduce the risk to the  portfolio  of a market  decline or
change in  interest  rates,  and,  by doing so,  provide an  alternative  to the
liquidation  of the Fund's  securities  positions and the resulting  transaction
costs.

         The Funds intend to engage in options transactions which are related to
financial  futures  contracts for hedging  purposes and in  connection  with the
hedging strategies described above.

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

FUTURES CONTRACTS

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

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


INTEREST RATE FUTURES CONTRACTS

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

         Currently,  interest rate futures contracts can be purchased or sold on
90-day U.S.  Treasury  bills,  U.S.  Treasury  bonds,  U.S.  Treasury notes with
maturities between 6 1/2 and 10 years,  Government National Mortgage Association
(GNMA)  certificates,  90-day  domestic  bank  certificates  of deposit,  90-day
commercial paper, and 90-day Eurodollar  certificates of deposit. It is expected
that futures  contracts  trading in  additional  financial  instruments  will be
authorized. The standard contract size is $100,000 for futures contracts in U.S.
Treasury bonds,  U.S. Treasury notes and GNMA  certificates,  and $1,000,000 for
the other designated  contracts.  While U.S. Treasury bonds, U.S. Treasury bills
and U.S.  Treasury  notes are  backed by the full  faith and  credit of the U.S.
government and GNMA certificates are guaranteed by a U.S. government agency, the
futures contracts in U.S.
government securities are not obligations of the U.S. Treasury.

INDEX BASED FUTURES CONTRACTS, OTHER THAN STOCK INDEX BASED

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

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

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

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

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

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

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

OPTIONS ON FINANCIAL FUTURES

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

         The Funds  intend to use  options on  financial  futures  contracts  in
connection with hedging strategies. In the future the Funds may use such options
for other purposes.

PURCHASE OF PUT OPTIONS ON FUTURES CONTRACTS

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

PURCHASE OF CALL OPTIONS ON FUTURES CONTRACTS

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

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

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

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

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

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

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

FEDERAL INCOME TAX TREATMENT

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

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

RISKS OF FUTURES CONTRACTS

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

         At best, the correlation between changes in prices of futures contracts
and of the  securities  being  hedged  can be only  approximate.  The  degree of
imperfection of correlation  depends upon  circumstances,  such as variations in
speculative  market demand for futures  contracts and for securities,  including
technical  influences  in futures  contracts  trading;  differences  between the
securities being hedged and the financial instruments and indexes underlying the
standard futures contracts  available for trading,  in such respects as interest
rate levels,  maturities  and  creditworthiness  of issuers,  or  identities  of
securities  comprising the index and those in a Fund's  portfolio.  In addition,
futures contract  transactions involve the remote risk that a party be unable to
fulfill its obligations and that the amount of the obligation will be beyond the
ability of the clearing broker to satisfy.  A decision of whether,  when and how
to hedge involves the exercise of skill and judgment,  and even a well conceived
hedge  may be  unsuccessful  to  some  degree  because  of  market  behavior  or
unexpected interest rate trends.

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

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

RISKS OF OPTIONS ON FUTURES CONTRACTS

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

Keystone State Tax Free Fund

NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies

Keystone State Tax Free Fund (formerly Keystone America State Tax Free Fund)
("FUND") was formed as a Massachusetts business trust on September 13, 1990.
Keystone Investment Management Company (formerly Keystone Custodian Funds,
Inc.) ("Keystone") is the Investment Adviser and Manager. The FUND currently
offers shares of five separate series evidencing interests in different
portfolios of securities: the Keystone Florida Tax Free Fund (formerly
Keystone America Florida Tax Free Fund) ("Florida Fund"), which was
established on September 19, 1990 and had no operations prior to December 28,
1990; the Keystone Massachusetts Tax Free Fund (formerly Keystone America
Massachusetts Tax Free Fund) ("Massachusetts Fund"), and the Keystone New
York Insured Tax Free Fund (formerly Keystone America New York Insured Tax
Free Fund) ("New York Fund"), which were established February 21, 1992 and
had no operations prior to February 4, 1994; the Keystone Pennsylvania Tax
Free Fund (formerly Keystone America Pennsylvania Tax Free Fund)
("Pennsylvania Fund"), which was established September 19, 1989 and had no
operations prior to December 27, 1990; and the Keystone Texas Tax Free Fund
(formerly Keystone America Texas Tax Free Fund) ("Texas Fund"), which was
established on February 21, 1992 and had no operations prior to March 2, 1992
(together the "Funds" and each individually a "Fund"). The FUND is registered
under the Investment Company Act of 1940 as an open-end investment company
and each of the Funds is registered as a nondiversified fund.

   Each Fund issues Class A, Class B and Class C shares. Class A shares are
sold subject to a maximum sales charge of 4.75% payable at the time of
purchase. Class B shares are sold subject to a contingent deferred sales
charge payable upon redemption within three calendar years after the year of
purchase. Class C shares are sold subject to a contingent deferred sales
charge payable upon redemption within one year of purchase. Class C shares
are available only through dealers who have entered into special distribution
agreements with Keystone Investment Distributors Company (formerly Keystone
Distributors, Inc.) ("KIDC"), the FUND's principal underwriter.

   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 members of current
management. Keystone Investor Resource Center, Inc. ("KIRC"), a wholly-owned
subsidiary of Keystone, is the FUND's transfer agent.

   The following is a summary of significant accounting policies consistently
followed by the FUND, in conformity with generally accepted accounting
principles.

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

<PAGE>

zation 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.

   Each Fund enters into currency and other financial futures contracts as a
hedge against changes in interest or currency exchange rates. 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 the Fund's taxable income. In
addition to market risk, the Fund is subject to the credit risk that the
other party will not complete the obligations of the contract.

B. When-issued or delayed delivery transactions arise when securities or
currencies are purchased or sold by a Fund with payment and delivery taking
place in the future in order to secure what is considered to be an
advantageous price and yield to the Fund at the time of entering into the
transaction. A separate account of liquid assets equal to the value of such
purchase commitments will be maintained until payment is made. When-issued
and delayed agreements are subject to risks from changes in value based upon
changes in the level of interest rates and other market factors, both before
and after delivery.

C. Securities transactions are accounted for no later than one business day
after the trade date. Realized gains and losses are recorded on the
identified cost basis. Interest income is recorded on the accrual basis.

D. Each Fund has qualified, and intends to qualify in the future, as a
regulated investment company under the Internal Revenue Code of 1986, as
amended ("Internal Revenue Code"). Thus, each Fund 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 tax-exempt interest portion of each dividend is declared uniformly based
on the ratio of each Fund's tax-exempt and taxable income for the entire
year. Each Fund intends to avoid excise tax liability by making the required
distributions under the Internal Revenue Code.

E. Organization expenses are being amortized to operations over a five-year
period on a straight-line basis. In the event any of the initial shares are
redeemed by any holder thereof during the five-year amortization period,
redemption proceeds will be reduced by any unamortized organization expenses
in the same proportion as the number of initial shares being redeemed bears
to the number of initial shares outstanding at the time of redemption.

2. Capital Share Transactions

The Trust agreement authorizes the issuance of an unlimited number of shares
of beneficial interest without par value. Transactions in shares of the FUND
were as follows:

   Each Fund bears some of the costs of selling its shares under a
Distribution Plan adopted with respect to its Class A, Class B, and Class C
shares pursuant to Rule 12b-1 under the Investment Company Act of 1940. Under
the Distribution Plan, the Fund pays KIDC, the principal underwriter and a
wholly-owned subsidiary of Keystone, amounts which in total may not exceed
the Distribution Plan maximum.

   Each Class A Distribution Plan provides for payments which are currently
limited to 0.15% annually of the average daily net asset value of Class A
shares to pay expenses of the distribution of Class A shares. Amounts paid by
each Fund to KIDC under the Class A Distribution Plan are currently used to
pay others such as brokers or dealers, service fees at an annual rate of
0.15% of the average net asset value of the shares sold by such others and
remaining outstanding on the books of the Funds for specified periods.

   Each Class B Distribution Plan provides for payments at an annual rate of
0.90% of the average daily net asset value of Class B shares to pay expenses
of the distribution of Class B shares. Amounts paid by each Fund under the
Class B Distribution Plan are currently used to pay others (dealers) (i) a
commission at the time of purchase normally equal to 3.00% of the value of
each share sold; and/or (ii) service fees currently at an annual rate of
0.15% of the average net asset value of shares sold by such others and
remaining outstanding on the books of the Funds for specified periods.

   Each Class C Distribution Plan provides for payments at an annual rate of
up to 0.90% of the average daily net asset value of Class C shares to pay
expenses of the distribution of Class C shares. Amounts paid by each Fund
under the Class C Distribution Plan are currently used to pay others
(dealers) (i) a commission at the time of purchase normally equal to 1.00% of
the value of each share sold; and (ii) beginning approximately fifteen months
after purchase a commission at an annual rate of 0.75% (subject to applicable
limitations imposed by the rules of the National Association of Securities
Dealers, Inc. ("NASD")) plus service fees at an annual rate of 0.15% of the
average net asset value of each share sold by such others and

remaining outstanding on the books of the Funds for specified periods.

   Each of the Distribution Plans may be terminated at any time by vote of
the Independent Trustees or by vote of a majority of the outstanding voting
shares of the respective class. However, after the termination of any of the
Distribution Plans, at the discretion of the Board of Trustees, payments to
KIDC may continue as compensation for its services which had been earned
while the distribution Plan was in effect.

   For the year ended March 31, 1995, the Florida Fund paid KIDC $66,246,
$345,221 and $140,405, the Massachusetts Fund paid KIDC $1,829, $40,387 and
$15,014, the New York Fund paid KIDC $3,025, $70,227, and $15,895, the

Class A, Class B, and Class C Distribution Plans.

4. Investment Management and Transactions with Affiliates

Under the terms of the Investment Management Agreement between Keystone and
the FUND, dated November 29, 1990, Keystone provides investment management
and administrative services to the FUND and its Funds. In return, Keystone is
paid a management fee computed and paid daily. The management fee is
calculated by applying percentage rates, which start at 0.55% and decline, as
net assets increase, to 0.25% per annum, to the net asset value of each Fund.

   During the year ended March 31, 1995, the Florida Fund, the Massachusetts
Fund, the New York Fund, the Pennsylvania Fund and the Texas Fund paid or
accrued to Keystone investment management and administrative services fees of
$515,205, $43,636, $63,808, $357,852 and $25,402, respectively, which
represented 0.52%, 0.55%, 0.55%, 0.54%, and 0.55%, respectively, of the
average net assets of the Funds on an annualized basis.

   During the year ended March 31, 1995, the Florida Fund, the Massachusetts
Fund, the New York Fund, the Pennsylvania Fund and the Texas Fund paid or
accrued to KII $13,052, $17,498, $17,698, $20,909 and $13,870, respectively,
for certain accounting and printing services and to KIRC $116,367, $15,568,
$25,831, $108,073, and $6,215, respectively, for transfer agent fees.

   Keystone has voluntarily agreed to limit all expenses incurred including
management fee of the Class A Shares of the Florida Fund, the Pennsylvania
Fund and the Texas Fund to 0.75% of average daily net assets and has limited
annual expenses of the Class B Shares and Class C Shares to 1.50% of average
daily net asset value.

   Keystone voluntarily limited the expenses, including the management fee,
of the Class A Shares of the Massachusetts Fund and the New York Fund to
0.35% until August 15, 1994, after which the expense limitation is being
increased by 0.10% every three months until May 15, 1995 when expenses will
be limited to 0.75% until December 31, 1995. Expenses of Class B Shares and
Class C Shares of those Funds were limited to 1.10% until August 15, 1994,
after which the expense limitations are being similarly increased until May
15, 1995 when expenses will be limited to 1.50% until December 31, 1995.
Keystone will not be required to make such reimbursement to an extent which
would result in a Fund's inability to qualify as a regulated investment
company under the provisions of the Internal Revenue Code. In accordance with
this voluntary expense limitation, Keystone reimbursed the Florida Fund, the
Massachusetts Fund, the New York Fund, the Pennsylvania Fund and the Texas
Fund (i) $89,179, $26,169, $22,366, $91,489 and $35,517, respectively, with
respect to each Fund's Class A Shares, (ii) $68,953, $64,511, $85,602,
$81,415 and $38,490, respectively, with respect to each Fund's Class B
Shares; and (iii) $31,739, $24,181, $18,786, $27,453 and $10,643,
respectively, with respect to each Fund's Class C Shares. Keystone does not
intend to seek repayment of these amounts.
<PAGE>

Certain officers and/or Directors of Keystone are also officers and/or
Trustees of the FUND. Officers of Keystone and affiliated Trustees receive no
compensation directly from the FUND. Currently, the Independent Trustees of
the FUND receive no compensation for their services.

5. Distributions to Shareholders

Each Fund intends to declare dividends from net investment income daily and
distribute to its shareholders such dividends monthly and to declare and
distribute all net realized long-term capital gains, if any, at least
annually. Distributions are determined in accordance with income tax
regulations. Distributions from tax basis net investment income and net
capital gains can exceed book basis net investment income and net capital
gains.

We have audited the financial statements, including the schedules of

statements. These financial statements and financial highlights are the
responsibility of the Funds' management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements and
financial highlights are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures
in the financial statements. Our procedures included confirmation of
securities owned as of March 31, 1995 by correspondence with the custodian
and brokers. An audit also includes assessing the accounting principles used
and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits provide
a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
portfolios of Keystone State Tax Free Fund as of March 31, 1995, the results
of their operations, the changes in their net assets and the financial
highlights for each of the periods specified in the index to financial

Free Fund for the twelve-month period which ended March 31, 1995.

   Following this letter we have included a performance summary for each
state fund and an interview with Keystone's municipal bond managers,
discussing the market's performance.

The year in review

In 1994, short-term interest rates rose more sharply than they had at any
time in the last five years. This had a significant impact on municipal bond
prices which declined as rates increased. Rates continued to rise throughout
most of the year, but by December the market had begun to stabilize. Since
January 1, 1995 bond prices have continued to advance, paving the way for a
return to performance that we believe should be closer to long-term
historical averages. Municipal bond returns, as represented by the Lehman
Municipal Bond Index, returned 7.46% for your Fund's twelve-month fiscal
period which ended March 31, 1995. The majority of this return was achieved
in the last four months of the period.(1)

The interest rate environment

The first few months of the fiscal year, which began April 1, 1994, were
difficult for all municipal bond investors. The Federal Reserve Bank (the
Fed) increased short-term rates in an effort to slow the growth of the
economy and to control inflation. The markets reacted strongly to the initial
change in the direction of interest rates. This reaction is not uncommon
during expansionary periods. During the twelve-month period, investors began
to adjust to the higher rate environment and price changes became more
moderate. Since the start of the new year, prices have rebounded slightly, an
indication that investors believe the Fed has brought inflation under
control.

Portfolio strategy

During the year, our strategy focused on maintaining tax-free income and
price stability. We selected higher coupon issues in an effort to take
advantage of greater potential income and the price stability they have
historically provided. We also emphasized bonds with maturities in the 15- to
20-year range, which have tended to be more stable than longer-term bonds.

Outlook

We believe the most dramatic interest rate increases are behind us. We
believe this may lead to improved price stability for municipal bonds in
1995. This is supported by our belief that the economy is slowing to a
sustainable, low inflation level. We also expect the decrease in the supply
of municipal bonds, coupled with level or rising demand for these bonds, to
be a positive factor for municipal bonds.

We believe municipal investors who weathered last year's storm can expect
to see a return to more normal market conditions over the coming year, with
less price fluctuation and attractive levels of income. We will continue to
manage Keystone State Tax Free Funds to seek valuable state and federal
tax-free income from a portfolio of quality municipal obligations.(2) We
appreciate your continued support of Keystone funds. If you have any
questions or comments, please feel free to write to us.

Sincerely,

/s/ Albert H. Elfner, III                   /s/ George S. Bissell

Keystone Florida Tax Free Fund Your Fund's objective is to earn generous
income, exempt from federal income tax, while preserving capital.(3) In
addition, your Fund seeks to ensure that its shares are exempt from the
Florida intangibles tax. The Fund is managed by Betsy Blacher, vice president
and head of Keystone's municipal bond department.

Performance

Class A shares returned 6.42% for the twelve-month period.

Class B shares returned 5.61% for the twelve-month period.

Class C shares returned 5.61% for the twelve-month period.

Portfolio Strategy

In response to the rising interest rate environment throughout the year, Fund
strategy focused on selecting high quality, higher coupon bonds in an attempt
to take advantage of their income potential. To increase the stability of the
portfolio, we favored bonds with call protection. We shortened the average
maturity from 22.5 years on March 31, 1994 to 19.5 years by March 31, 1995 to
lower our interest rate risk. As of March 31, 1995 the average quality of the
Fund's holdings was AA+, with 40.9% of the bonds rated AAA, the highest
possible rating.

Economic Environment

Florida's economy continues to diversify beyond tourism to include
international business development, particularly in Miami and Orlando. The
state has been able to attract manufacturing firms due to its low business
costs. The employment situation compares favorably to the national average;
Florida ranks second in the number of jobs generated in 1994. The state's
fiscal position remains strong as well; overall debt levels are moderate and
the general fund balance has posted a healthy surplus for three years in a
row.

Outlook

We believe Florida's long-term outlook is stable. Due to its historical
popularity as a retirement area, Florida continues to have a high
concentration of retirees living on fixed incomes. This has somewhat
cushioned Floridians from the ups and downs of the business cycle.

capital.(6) The Fund is managed by Daniel R. Rabasco, vice president in
Keystone's municipal bond department.

Performance

Class A shares returned 6.23% for the twelve-month period.

Class B shares returned 5.41% for the twelve-month period.

Class C shares returned 5.20% for the twelve-month period.

Portfolio Strategy

The life of your Fund has coincided with a period of unusual price
fluctuations in the municipal bond market. In response to the rising interest
rate environment throughout the year, Fund strategy focused on selecting high
quality, higher coupon bonds in an attempt to take advantage of their income
potential. To increase the stability of the portfolio, we favored bonds with
call protection. The average maturity of the Fund's holdings was 19.4 years
on March 31, 1995 and the average quality was A, with 20.7% of the bonds
rated AAA, the highest possible rating.

Economic Environment

The Commonwealth's credit trend has been stable. Improved economic conditions
and more conservative fiscal management have produced positive fund bal ances
for the state treasury in each of the past five years. The governor's
proposed 1996 budget contains moderate increases in spending and a
significant surplus is expected for that year. Bond issuance for capital
improvements, including MBTA bonds, is expected to total $6.3 billion over
the next five years.

The Massachusetts unemployment rate has been close to the national average.
Much of the job growth has been in business services such as accounting,
engineering, non-hospital health care and software development. Employment in
defense and computer manufacturing have continued to decrease.

Outlook

Long-term, we believe the highly educated Massachusetts work force should
help in developing new high technology industries. The economy should also
receive a boost from increases in international trade--Massachusetts
currently ranks eleventh in the nation in exports. Public infrastructure
projects, specifically the Central Artery and Boston Harbor cleanup projects,
should also continue to provide job opportunities.

Class B shares returned 6.28% for the twelve-month period.
Class C shares returned 6.18% for the twelve-month period.

Portfolio Strategy

The life of your Fund has coincided with a period of unusual price
fluctuations in the municipal bond market. In response to the rising interest
rate environment throughout the year, Fund strategy focused on selecting high
quality, higher coupon bonds in an effort to take advantage of their income
potential. To increase the stability of the portfolio, we favored bonds with
call protection. The average maturity of the Fund's holdings was 19.6 years
on March 31, 1995 and the average quality was AA+, with 93.2% of the bonds
rated AAA, the highest possible rating.

Economic Environment

New York's economic recovery slowed in 1994, due primarily to a downturn in
the securities industry. After improving moderately throughout 1993,
employment growth virtually ceased after mid-1994. The state's unemployment
rate continued to exceed the national average.

   While New York posted general fund operating surpluses in fiscal 1993 and
1994, current projections call for a $259 million shortfall in fiscal 1995
and a deficit of $5.0 billion for 1996. The primary components of the 1996
deficit are revenue and expenditure imbalances. The governor's budget
proposes to eliminate the projected gap through social welfare cost
containment, state agency restructuring, freezes in local aid and various
revenue increases.

Outlook

Given the weakness of the state's budget, we believe it is unlikely that the
governor's full tax cut plan will be approved, although a significant portion
of it may pass. Any tax cut package would add further stress to the budget.
Under these circumstances, we believe that your Fund's emphasis on insured
bonds should provide additional protection and stability.

Economic Environment

Over the past ten years, Pennsylvania has succeeded in diversifying its
economy to offset losses in manufacturing and mining. Pittsburgh and
Philadelphia, which account for about half of the Commonwealth's population,
have increased their roles as trade, financial and medical centers. The
Pittsburgh area has also benefited from growth in the high technology sector.
Pennsylvania's large agricultural base adds further breadth to the economy.

   Pennsylvania has posted positive general fund balances for the past three
years through conservative fiscal management. Although the new governor
called for significant tax cuts during his campaign, the 1996 budget proposes
only modest cuts, to be funded primarily through reductions in Medicaid
spending.

Outlook

In the long term, Pennsylvania could become an attractive lower-cost
environment for industry. The Commonwealth's highly educated work force,
strong distribution network and ample natural resources all are assets. We
expect Pennsylvania's conservative and consistent fiscal policies to continue
to be favorable to municipal bond investors.

Economic Environment

The Texas economy has performed better than the national economy since 1989.
The state has had a record of strong economic growth and financial
performance. The Lone Star state has also continued to diversify from its
reliance on the energy industry and job growth has been steady since
September 1990.

   Continued improvement in the economy has produced strong revenue growth in
the face of rising expenditures. Texas finished fiscal year 1994 with a
general fund surplus of approximately $2.2 billion, and has ended each
of the past six years with significant surpluses.

Outlook

We believe Texas should continue to enjoy strong economic performance because
of its growing high tech sector and its role as a low cost alternative for
business. The state also benefits from its role as a transportation and
distribution center due to its central US location. While rising costs for
Medicaid, education and prison facilities present future fiscal challenges,
we believe the state's strong economic growth combined with its prudent
fiscal management should enable it to maintain its record of strong fiscal
performance.

Class A shares were introduced on March 2, 1992. Performance is reported at
the current maximum front-end sales charge of 4.75%.

Class B shares were introduced on February 1, 1993. Performance reflects the
deduction of the contingent deferred sales charge, a maximum of 3%. If you
have not redeemed, the returns under "w/o (without) sales charge" are more
appropriate for the period.

Class C shares were introduced on February 1, 1993. Performance reflects the
return you would have received after holding shares for one year or more and
redeeming after the end of that period.

The investment return and principal value will fluctuate so that your shares,
when redeemed, may be worth more or less than the original cost. Performance
for each class will differ.

You may exchange your shares for another Keystone fund by phone or in writing
for a $10 fee. The exchange fee is waived for individual investors who make
an exchange using Keystone's Automated Response Line (KARL). The Fund
reserves the right to change or terminate the exchange offer.

                                A Discussion With
                             Your Fund's Management

         The Keystone State Tax Free Funds are managed by Keystone's
     municipal bond team, which includes portfolio managers Betsy Blacher
 and Daniel R. Rabasco. The team is comprised of six investment professionals
          who are dedicated to researching, analyzing and evaluating
        municipal bonds for each fund. We asked them several questions
        about the market's recent performance. Their responses follow.

Q What do Keystone State Tax Free Funds offer investors?

A The Funds are designed for tax-sensitive investors. Each portfolio seeks
  consistent, attractive income that is exempt from federal income and state
  taxes as applicable.(17) In states that tax personal property or intangible
  assets (Florida and Pennsylvania), we also seek tax-exempt status. The
  Funds offer professional management and diversification from a portfolio of
  quality municipal bonds. We manage each state fund with careful attention
  to credit quality and financial stability.

Q How did municipal bonds perform over the past year?

A Municipal bonds had their worst performance in over five years. The Federal
  Reserve Bank's program of raising short-term interest rates to control
  inflation caused municipal bond yields to rise and prices to fall for most
  of 1994. But while it was a difficult year for investors, it was also a
  textbook example of the value of investing for the long term. One year
  after the rate increases began, rates have finally leveled off and
  municipal bond prices have recovered significantly. Price appreciation
  since the first day of 1995 has made up for more than half of the declines
  experienced in 1994.

Q What was your investment strategy during the year?

A When interest rates were rising, we generally shortened the maturity of the
  Funds' holdings to minimize price volatility. We focused on high quality
  bonds with higher coupons to increase tax-free income, and kept more cash
  on hand. While this strategy did not prevent price declines, it helped
  reduce share price fluctuations.

  Throughout the year we emphasized "non-callable" bonds--bonds which cannot
  be called back by their issuers and repaid early. This tends to increase
  portfolio stability because we can count on a steady stream of income.
  Toward the end of the fiscal year, we lengthened maturities slightly, in an
  effort to increase return potential. We also reduced our cash position
  during the second half of the period and became more fully invested again.

Q What is your outlook for the municipal bond market?

A While we believe the worst effects of rising rates are behind us, we are
  still cautious in the short-term. We believe there may be brief periods of
  declining bond prices as the economy settles to a level of sustainable, low
  inflation growth. We will most likely use these periods as buying
  opportunities, because we also believe the long-term outlook for municipal
  bonds is positive. We expect the combination of higher yields and
  relatively low inflation should continue to provide investors with very
  attractive after-tax returns.

Q How are supply and demand?

A The supply of new municipal bonds has been shrinking. We expect this to
  continue because a large number of bonds will likely be called and redeemed
  this year. Demand has remained strong for municipal

  bonds as investors are finding them one of the few remaining tax shelters.
  We think these factors should provide support for municipal bond prices in
  1995.

Q What types of bonds do you favor in today's environment?


A We are extremely selective about fund holdings. We prefer bonds rated A or
  better. We maintain core positions of relatively high coupon bonds to
  generate strong income streams. Our current sector emphasis is on quality
  essential services and general obligation bonds--sectors that we believe
  should do well in a slowing economy. We always evaluate how a potential
  holding will fit with the existing composition of each portfolio, and
  strive to build portfolios that are diversified across industry sectors and
  maturities.

Q Is this a good time for investors to buy tax free funds?

A Yes, we believe it is. For tax-sensitive investors, municipal bond funds
  are one of the few remaining investments for tax-free income. While it is
  impossible to know how the market will perform, share prices remain at
  attractive levels, and this may be a smart time to consider adding to
  tax-exempt holdings. Of course, there is always risk associated with
  investing, but we think the portfolios of Keystone State Tax Free Fund will
  continue to offer investors a diversified, professionally managed
  opportunity for income that is exempt from federal and state (and city)
  taxes as applicable.(18)

This chart graphically compares your Fund's total return performance to
certain investment indexes. It is the result of fund performance guidelines
issued by the Securities and Exchange Commission. The intent is to provide
investors with more information about their investment.

Components of the Chart

The chart is composed of several lines that represent the accumulated value
of an initial $10,000 investment for the period indicated. The lines
illustrate a hypothetical investment in:

1. Your Keystone State Tax Free Fund

Your Fund seeks high current income, exempt from federal income taxes, while
preserving capital by investing in high quality municipal bonds. In addition,
each Fund also seeks to provide a maximum level of income that is exempt from
state and local income or personal property taxes, as applicable. Returns are
quoted after deducting front-end or contingent deferred sales charges (if
applicable), fund expenses, and transaction costs. The return also includes
reinvestment of all distributions.

2. Lehman Municipal Bond Index (LMBI)

The LMBI is a broad-based, unmanaged market index of securities issued by
state and local governments. It represents the price change and coupon income
of several thousand securities with various maturities and qualities.
Securities are selected and compiled by Lehman Brothers, Inc. according to
criteria that may be unrelated to your Fund's investment objective. The index
does not include transaction costs associated with buying and selling
securities, and does not hold cash to meet redemptions. It would be difficult
for most individual investors to duplicate this index.

*******************************************************************************

3. Consumer Price Index (CPI)

This index is a widely recognized measure of the cost of goods and services
produced in the U.S. The index contains factors such as prices of services,
housing, food, transportation and electricity which are compiled by the US
Bureau of Labor Statistics. The CPI is generally considered a valuable
benchmark for investors who seek to outperform increases in the cost of
living.

These indexes do not include transaction costs associated with buying and
selling securities, and do not hold cash to meet redemptions. It would be
difficult for most individual investors to duplicate these indexes.

Understanding What the Chart Means

The chart demonstrates your Fund's total return performance in relation to a
well known investment index and to increases in the cost of living. It is
important to understand what the chart shows and does not show.

This illustration is useful because it charts Fund and index performance over
the same time frame and over a long period. Long-term performance is a more
reliable and useful measure of performance than measurements of short-term
returns or temporary swings in the market. Your financial adviser can help
you evaluate fund performance in conjunction with the other important
financial considerations such as safety, stability and consistency.

Limitations of the Chart

The chart, however, limits the evaluation of Fund performance in several
ways. Because the measurement is based on total returns over an extended
period of time, the comparison often favors those funds which emphasize
capital appreciation when the market is rising. Likewise, when the market is
declining, the comparison usually favors those funds which take less risk.

Performance Can Be Distorted

Funds which are more conservative in their orientation and which place an
emphasis on capital preservation will tend to compare less favorably when the
market is rising. In addition, funds which have income as one of their
objectives also will tend to compare less favorably to relevant indexes.

Past performance is no guarantee of future
results. The Lehman Municipal Bond Index
and the Consumer Price Index are from
February 28, 1992.
*******************************************************************************

Indexes may also reflect the performance of some securities which a fund may
be prohibited from buying. A bond fund, for example, may be limited to
investments in only high quality bonds, or a stock fund may only be able to
buy stocks that have been traded on a stock exchange for a minimum number of
years or of a certain company size. Indexes usually do not have the same
investment restrictions as your Fund.

Indexes Do Not Include Costs of Investing

The comparison is further limited in its utility because the indexes do not
take into account any deductions for sales charges, transaction costs or
other fund expenses. Your Fund's performance figures do reflect such
deductions. Sales charges--whether up-front or deferred--pay for the cost of
the investment advice of your financial adviser. Transaction costs pay for
the costs of buying and selling securities for your Fund's portfolio. Fund
expenses pay for the costs of investment management and various shareholder
services. None of these costs are reflected in index total returns. The
comparison is not completely realistic because an index cannot be duplicated
by an investor--even an unmanaged index--without incurring some charges and
expenses.

One of Several Measures

The chart is one of several tools you can use to understand your investment.
It should be read in conjunction with the Fund's prospectus, and annual and
semiannual reports. Also, your financial adviser, who understands your
personal financial situation, can best explain the features of your Keystone
fund and how it applies to your financial needs.

Future Returns May Be Different

Shareholders also should be mindful that the long-run performance of either
the Fund or the indexes is not representative of what shareholders should
expect to receive from their Fund investment in the future; it is presented
to illustrate only past performance and is not a guarantee of future returns.

Keystone State Tax Free Fund

NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies

Keystone State Tax Free Fund (formerly Keystone America State Tax Free Fund)
("FUND") was formed as a Massachusetts business trust on September 13, 1990.
Keystone Investment Management Company (formerly Keystone Custodian Funds,
Inc.) ("Keystone") is the Investment Adviser and Manager. The FUND currently
offers shares of five separate series evidencing interests in different
portfolios of securities: the Keystone Florida Tax Free Fund (formerly
Keystone America Florida Tax Free Fund) ("Florida Fund"), which was
established on September 19, 1990 and had no operations prior to December 28,
1990; the Keystone Massachusetts Tax Free Fund (formerly Keystone America
Massachusetts Tax Free Fund) ("Massachusetts Fund"), and the Keystone New
York Insured Tax Free Fund (formerly Keystone America New York Insured Tax
Free Fund) ("New York Fund"), which were established February 21, 1992 and
had no operations prior to February 4, 1994; the Keystone Pennsylvania Tax
Free Fund (formerly Keystone America Pennsylvania Tax Free Fund)
("Pennsylvania Fund"), which was established September 19, 1989 and had no
operations prior to December 27, 1990; and the Keystone Texas Tax Free Fund
(formerly Keystone America Texas Tax Free Fund) ("Texas Fund"), which was
established on February 21, 1992 and had no operations prior to March 2, 1992
(together the "Funds" and each individually a "Fund"). The FUND is registered
under the Investment Company Act of 1940 as an open-end investment company
and each of the Funds is registered as a nondiversified fund.

   Each Fund issues Class A, Class B and Class C shares. Class A shares are
sold subject to a maximum sales charge of 4.75% payable at the time of
purchase. Class B shares are sold subject to a contingent deferred sales
charge payable upon redemption within three calendar years after the year of
purchase. Class C shares are sold subject to a contingent deferred sales
charge payable upon redemption within one year of purchase. Class C shares
are available only through dealers who have entered into special distribution
agreements with Keystone Investment Distributors Company (formerly Keystone
Distributors, Inc.) ("KIDC"), the FUND's principal underwriter.

   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 members of current
management. Keystone Investor Resource Center, Inc. ("KIRC"), a wholly-owned
subsidiary of Keystone, is the FUND's transfer agent.

   The following is a summary of significant accounting policies consistently
followed by the FUND, in conformity with generally accepted accounting
principles.

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

                                      60
<PAGE>

zation 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.

   Each Fund enters into currency and other financial futures contracts as a
hedge against changes in interest or currency exchange rates. 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 the Fund's taxable income. In
addition to market risk, the Fund is subject to the credit risk that the
other party will not complete the obligations of the contract.

B. When-issued or delayed delivery transactions arise when securities or
currencies are purchased or sold by a Fund with payment and delivery taking
place in the future in order to secure what is considered to be an
advantageous price and yield to the Fund at the time of entering into the
transaction. A separate account of liquid assets equal to the value of such
purchase commitments will be maintained until payment is made. When-issued
and delayed agreements are subject to risks from changes in value based upon
changes in the level of interest rates and other market factors, both before
and after delivery.

C. Securities transactions are accounted for no later than one business day
after the trade date. Realized gains and losses are recorded on the
identified cost basis. Interest income is recorded on the accrual basis.

D. Each Fund has qualified, and intends to qualify in the future, as a
regulated investment company under the Internal Revenue Code of 1986, as
amended ("Internal Revenue Code"). Thus, each Fund 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 tax-exempt interest portion of each dividend is declared uniformly based
on the ratio of each Fund's tax-exempt and taxable income for the entire
year. Each Fund intends to avoid excise tax liability by making the required
distributions under the Internal Revenue Code.

E. Organization expenses are being amortized to operations over a five-year
period on a straight-line basis. In the event any of the initial shares are
redeemed by any holder thereof during the five-year amortization period,
redemption proceeds will be reduced by any unamortized organization expenses
in the same proportion as the number of initial shares being redeemed bears
to the number of initial shares outstanding at the time of redemption.

2. Capital Share Transactions

The Trust agreement authorizes the issuance of an unlimited number of shares
of beneficial interest without par value. Transactions in shares of the FUND
were as follows:

   Each Fund bears some of the costs of selling its shares under a
Distribution Plan adopted with respect to its Class A, Class B, and Class C
shares pursuant to Rule 12b-1 under the Investment Company Act of 1940. Under
the Distribution Plan, the Fund pays KIDC, the principal underwriter and a
wholly-owned subsidiary of Keystone, amounts which in total may not exceed
the Distribution Plan maximum.

   Each Class A Distribution Plan provides for payments which are currently
limited to 0.15% annually of the average daily net asset value of Class A
shares to pay expenses of the distribution of Class A shares. Amounts paid by
each Fund to KIDC under the Class A Distribution Plan are currently used to
pay others such as brokers or dealers, service fees at an annual rate of
0.15% of the average net asset value of the shares sold by such others and
remaining outstanding on the books of the Funds for specified periods.

   Each Class B Distribution Plan provides for payments at an annual rate of
0.90% of the average daily net asset value of Class B shares to pay expenses
of the distribution of Class B shares. Amounts paid by each Fund under the
Class B Distribution Plan are currently used to pay others (dealers) (i) a
commission at the time of purchase normally equal to 3.00% of the value of
each share sold; and/or (ii) service fees currently at an annual rate of
0.15% of the average net asset value of shares sold by such others and
remaining outstanding on the books of the Funds for specified periods.

   Each Class C Distribution Plan provides for payments at an annual rate of
up to 0.90% of the average daily net asset value of Class C shares to pay
expenses of the distribution of Class C shares. Amounts paid by each Fund
under the Class C Distribution Plan are currently used to pay others
(dealers) (i) a commission at the time of purchase normally equal to 1.00% of
the value of each share sold; and (ii) beginning approximately fifteen months
after purchase a commission at an annual rate of 0.75% (subject to applicable
limitations imposed by the rules of the National Association of Securities
Dealers, Inc. ("NASD")) plus service fees at an annual rate of 0.15% of the
average net asset value of each share sold by such others and

                                      64

remaining outstanding on the books of the Funds for specified periods.

   Each of the Distribution Plans may be terminated at any time by vote of
the Independent Trustees or by vote of a majority of the outstanding voting
shares of the respective class. However, after the termination of any of the
Distribution Plans, at the discretion of the Board of Trustees, payments to
KIDC may continue as compensation for its services which had been earned
while the distribution Plan was in effect.

   For the year ended March 31, 1995, the Florida Fund paid KIDC $66,246,
$345,221 and $140,405, the Massachusetts Fund paid KIDC $1,829, $40,387 and
$15,014, the New York Fund paid KIDC $3,025, $70,227, and $15,895, the
Pennsylvania Fund paid KIDC $44,697, $244,404 and $81,781, and the Texas Fund
paid KIDC $2,847, $18,613 and $5,377, respectively, pursuant to each Fund's
Class A, Class B, and Class C Distribution Plans.

   Under a Rule of the NASD, the maximum uncollected amounts for which KIDC
may seek payment from the FUND under its Class B Distribution Plans are
$3,196,058, $384,672, $728,940, $1,923,455, and $145,495, respectively, for
the Florida Fund, the Massachusetts Fund, the New York Fund, the Pennsylvania
Fund and the Texas Fund as of March 31, 1995. The maximum uncollected amounts
for which KIDC may seek payment from the FUND under its Class C Distribution
Plans are $1,218,232, $118,845, $176,106, $743,501, and $58,326,

4. Investment Management and Transactions with Affiliates

Under the terms of the Investment Management Agreement between Keystone and
the FUND, dated November 29, 1990, Keystone provides investment management
and administrative services to the FUND and its Funds. In return, Keystone is
paid a management fee computed and paid daily. The management fee is
calculated by applying percentage rates, which start at 0.55% and decline, as
net assets increase, to 0.25% per annum, to the net asset value of each Fund.

   During the year ended March 31, 1995, the Florida Fund, the Massachusetts
Fund, the New York Fund, the Pennsylvania Fund and the Texas Fund paid or
accrued to Keystone investment management and administrative services fees of
$515,205, $43,636, $63,808, $357,852 and $25,402, respectively, which
represented 0.52%, 0.55%, 0.55%, 0.54%, and 0.55%, respectively, of the
average net assets of the Funds on an annualized basis.

   During the year ended March 31, 1995, the Florida Fund, the Massachusetts
Fund, the New York Fund, the Pennsylvania Fund and the Texas Fund paid or
accrued to KII $13,052, $17,498, $17,698, $20,909 and $13,870, respectively,
for certain accounting and printing services and to KIRC $116,367, $15,568,
$25,831, $108,073, and $6,215, respectively, for transfer agent fees.

   Keystone has voluntarily agreed to limit all expenses incurred including
management fee of the Class A Shares of the Florida Fund, the Pennsylvania
Fund and the Texas Fund to 0.75% of average daily net assets and has limited
annual expenses of the Class B Shares and Class C Shares to 1.50% of average
daily net asset value.

   Keystone voluntarily limited the expenses, including the management fee,
of the Class A Shares of the Massachusetts Fund and the New York Fund to
0.35% until August 15, 1994, after which the expense limitation is being
increased by 0.10% every three months until May 15, 1995 when expenses will
be limited to 0.75% until December 31, 1995. Expenses of Class B Shares and
Class C Shares of those Funds were limited to 1.10% until August 15, 1994,
after which the expense limitations are being similarly increased until May
15, 1995 when expenses will be limited to 1.50% until December 31, 1995.
Keystone will not be required to make such reimbursement to an extent which
would result in a Fund's inability to qualify as a regulated investment
company under the provisions of the Internal Revenue Code. In accordance with
this voluntary expense limitation, Keystone reimbursed the Florida Fund, the
Massachusetts Fund, the New York Fund, the Pennsylvania Fund and the Texas
Fund (i) $89,179, $26,169, $22,366, $91,489 and $35,517, respectively, with

Keystone State Tax Free Fund
Seeks generous tax-free income from high quality municipal bonds

Dear Shareholder:

We are pleased to report on the performance of Keystone State Tax Free Fund
for the six-month period which ended September 30, 1995. Following this
letter we have included a performance summary for each state fund and an
interview with Keystone's municipal bond department, discussing the market's
performance.

Municipal bond market rebounded

After an unsettled market in 1994, municipal bond investors were rewarded for
their patience over the past six months. Interest rates trended down during
the period and bond prices rose. Low inflation combined with slow but steady
economic growth to create a more positive investment environment. The Lehman
Municipal Bond Index(1) returned 5.36% for the six-month period and 11.19%
for the twelve-month period which ended September 30, 1995.

   The Federal Reserve Board succeeded in engineering a soft landing for the
U.S. economy which created a favorable environment for municipal bonds.
Compared to taxable Treasury bonds, municipals were relatively cheap. In
fact, municipal bond yields averaged about 92% of the yield on comparable
long-term U.S. Treasury bonds, making them especially attractive on an
after-tax basis.

   During the six months, we continued to emphasize bonds with maturities in
the 20-year range to pursue higher income with lower risk than longer term
bonds. We selected higher coupon issues to take advantage of greater
potential income and stability, and favored non-callable bonds for their
price appreciation potential and predictable income flow.

   We expect the interest rate environment to remain stable over the coming
months as the economy adjusts to a slower pace of economic growth.
Shareholders should not be surprised to see modest declines in yields
consistent with lower interest rates, but tight municipal bond supply and
steady to rising demand should continue to be a positive factor for municipal
bond prices. Keystone State Tax Free Funds maintain their objective of
seeking valuable state and federal tax-free income from a portfolio of
quality municipal obligations.(1)
   We appreciate your continued support of Keystone funds. If you have any
questions or comments, please feel free to write to us.

Sincerely,

/s/ Albert H. Elfner, III

Keystone Florida Tax Free Fund

Your Fund's Performance

Your Fund's objective is to earn generous income, exempt from federal income
tax, while preserving capital.(2) In addition, your Fund seeks to ensure that
its shares are exempt from the Florida intangibles tax. Your Fund is managed
by Betsy Blacher, senior vice president and head of Keystone's municipal bond
department.

Performance

Class A shares returned 5.21% for the six-month period and 10.89% for the
twelve-month period.

Class B shares returned 4.93% for the six-month period and 10.19% for the
twelve-month period.

Class C shares returned 4.82% for the six-month period and 10.13% for the
twelve-month period.

Portfolio Strategy

Your Fund's portfolio was well positioned to take advantage of the declining
interest rate environment during the six-month period. We continued to use a
"barbell" strategy, with a heavy weighting in AAA- rated bonds for stability
and in BBB-rated issues (the lowest investment grade category) for yield and
price appreciation potential. We also invested in some industrial revenue
bonds for attractive income. Your Fund's average maturity was 20.8 years on
September 30, 1995, up from 19.5 years on March 31, 1995. As of September 30,
1995, your Fund's average quality was AA, the second highest bond rating.

Economic Environment

Florida is now the fourth largest state in the nation due to rapid population
growth. Tourism has improved considerably after a slight decline last year,
and the

employment situation compares favorably with the national average.
Offsetting this are slower income and household growth. Estimates project
this trend to continue which may affect other areas of growth, such as
construction activity. Tax revenues have been higher than expected, however,
and the state continues to experience a surplus in the general fund.

Outlook

We believe Florida's long-term outlook is stable, but it faces challenges in
funding for school construction, prison facilities and other infrastructure
needs. Floridians are reluctant to approve sales tax increases for these
purposes, so revenues will need to be generated in other ways. We will be
monitoring political and budgetary news as well as household and income
growth in the coming months.

    ratings assigned by another nationally recognized statistical rating
    organization.

Keystone Massachusetts Tax Free Fund

Your Fund's Performance

Your Fund's objective is to earn generous income, exempt from federal and
state income tax, while preserving capital.(5) It is managed by Daniel A.
Rabasco, vice president in Keystone's municipal bond department.

Performance

Class A shares returned 4.20% for the six-month period and 9.66% for the
twelve-month period.

Class B shares returned 3.91% for the six-month period and 8.99% for the
twelve-month period.

Class C shares returned 3.91% for the six-month period and 8.96% for the
twelve-month period.

Portfolio Strategy

Your Fund's portfolio was well positioned to take advantage of the declining
interest rate environment during the six-month period. We maintained our
emphasis on high quality, higher coupon bonds and favored bonds with call
protection. We are also invested in several industrial revenue bonds for
attractive income. Your Fund's average maturity was 19.4 years on September
30, 1995, unchanged from March 31, 1995. As of September 30, 1995, your
Fund's average quality was A, the third highest bond rating.

Economic Environment

The Commonwealth's economy is fairly stable. Job losses due to declines in
defense spending and consolidation in the banking industry have been
generally offset by growth in the service sector. Improving eco-

nomic conditions and more conservative fiscal management have resulted in
positive fund balances for the state treasury in each of the past five years,
a trend that is expected to continue. Medicaid expenditures are expected to
increase only marginally for fiscal year 1995.

Outlook

We don't expect to see significant growth in Massachusetts. However, we
continue to see economic opportunities for the Bay State from increases in
international trade and the ongoing public infrastructure projects. The
central artery and Boston Harbor cleanup projects should continue to be a
positive influence on the economy.

Keystone New York Insured Tax Free Fund

Your Fund's Performance

Your Fund's objective is to earn generous income, exempt from federal, state,
and New York City income tax, while preserving capital.(8) It is managed by
Daniel A. Rabasco, vice president in Keystone's municipal bond department.

Performance

Class A shares returned 4.67% for the six-month period and 10.41% for the
twelve-month period.

Class B shares returned 4.28% for the six-month period and 9.66% for the
twelve-month period.

Class C shares returned 4.39% for the six-month period and 9.62% for the
twelve-month period.

Portfolio Strategy

Your Fund's portfolio was well positioned to take advantage of the declining
interest rate environment during the six-month period. We maintained our
emphasis on high quality, higher coupon insured bonds and favored bonds with
call protection. Your Fund's average maturity was 20.1 years on September 30,
1995, up slightly from 19.6 years on March 31, 1995. As of September 30,
1995, your Fund's average quality was AA+, the second highest bond rating.

Economic Environment
New York's economy continued to lag that of the nation, affected in part by
contraction in the banking and manufacturing sectors. For August 1995, the
state's unemployment rate was 7.1% compared to the

national average of 5.6%. A recent development is that New York ended fiscal
year 1995 with a positive fund balance and expects another positive balance
for 1996.

Outlook

Implementation of tax cuts that were part of the 1995 fiscal year budget may
strain the long term finances of the state. In addition, economic performance
is not expected to rebound appreciably, weighed down by significant social
service costs. With the challenging years that lie ahead for New York, we
believe that your Fund's emphasis on insured bonds should provide valuable
protection and stability.

Keystone Pennsylvania Tax Free Fund

Your Fund's Performance

Your Fund's objective is to earn generous income, exempt from federal, state,
and city income tax, while preserving capital.(11) In addition, your Fund
seeks to ensure that its shares are exempt from Pennsylvania's personal
property tax. It is managed by Daniel A. Rabasco, vice president in
Keystone's municipal bond department.

Performance

Class A shares returned 4.76% for the six-month period and 8.80% for the
twelve-month period.

Class B shares returned 4.31% for the six-month period and 7.95% for the
twelve-month period.

Class C shares returned 4.40% for the six-month period and 7.99% for the
twelve-month period.

Portfolio Strategy

Your Fund's portfolio was well positioned to take advantage of the declining
interest rate environment during the six-month period. We continued to use a
"barbell" strategy, with a heavy weighting in AAA- rated bonds for price
appreciation potential and in BBB-rated issues (the lowest investment grade
category) for yield. We also invested in some industrial revenue bonds for
attractive income. Your Fund's average maturity was 20.6 years on September
30, 1995, basically unchanged from 20.8 years on March 31, 1995. As of
September 30, 1995, your Fund's average quality was AA+, the second highest
bond rating.

Economic Environment

Pennsylvania's well diversified economy includes strong financial, medical
and technology sectors as well as its historical agricultural base. Stronger

business taxes in fiscal year 1994 resulted in a $540 million general fund
surplus. Between $54 million and $111 million of the surplus will be
transferred to the budget stabilization fund, a positive indicator of
longer-term fiscal strength. Pennsylvania's unemployment rate of 5.5% as of
July, 1995 is roughly the same as the national rate.

Outlook
We expect Pennsylvania's conservative and consistent fiscal policies to
continue to be favorable to municipal bond investors. Even though job growth
has slowed recently, the new diversified Pennsylvania economy should track
the nation. Additionally, Pittsburgh and Philadelphia, which account for
about half of the Commonwealth's population may also experience a boost from
strength in the high technology and financial services sectors.

Keystone Texas Tax Free Fund

Your Fund's Performance

Your Fund's objective is to earn generous income, exempt from federal income
tax, while preserving capital.(14) Your Fund seeks to achieve its objective
by investing primarily in Texas municipal securities. It is managed by Daniel
A. Rabasco, vice president in Keystone's municipal bond department.

Performance

Class A shares returned 5.44% for the six-month period and 9.58% for the
twelve-month period.

Class B shares returned 5.05% for the six-month period and 8.82% for the
twelve-month period.

Class C shares returned 5.16% for the six-month period and 9.12% for the
twelve-month period.

Portfolio Strategy

Your Fund's portfolio was well positioned to take advantage of the declining
interest rate environment during the six-month period. We maintained our
emphasis on high quality, higher coupon bonds and favored bonds with call
protection. We also invested in some industrial revenue bonds for attractive
income. Your Fund's average maturity was 17.6 years on September 30, 1995,
down slightly from 18.1 years on March 31, 1995. As of September 30, 1995,
your Fund's average quality was AA, the second highest bond rating.

Economic Environment

Texas continues to experience strong employment growth. Between August 1994
and August 1995 the Lone Star state added almost 250,000 jobs and employment
increased 3.2%. Texas recently passed

New York as the second most populous state in the nation. Continued
improvement in the economy has produced strong revenue growth in the face of
rising expenditures. Texas finished fiscal year 1995 with a general fund
surplus of approximately $2.1 billion, and has ended each of the past seven
years with significant surpluses.

Outlook

We believe Texas should continue to enjoy strong employment growth. Its plan
to save on Medicaid costs through use of managed care is currently awaiting
federal waiver, and its program for education reform was finally upheld by
the State Supreme Court. We believe the state's large, growing and
increasingly diversified economy and its prudent and innovative fiscal
management should help it maintain its record of strong fiscal performance.

Keystone State Tax Free Fund

                              A Discussion With
                            Your Fund's Management
           Keystone State Tax Free Funds are managed by Keystone's
             municipal bond team, headed by senior vice president
           Betsy Blacher. The team is comprised of five investment
        professionals who are dedicated to researching, analyzing and
           evaluating municipal bonds for each fund. We asked them
           several questions about the market's recent performance.
                           Their responses follow.

Q  What do Keystone State Tax Free Funds offer investors?

A  The Funds are designed for tax-sensitive investors. The Funds offer
professional management and diversification from a portfolio of quality
municipal bonds. We manage each state fund with careful attention to credit
quality and financial stability. Each portfolio seeks consistent, attractive
income that is exempt from federal income and state (and city) taxes as
applicable.(17) In states that tax intangible assets or personal property
(Florida and Pennsylvania), we also seek tax-exempt status.

Q  How did economic conditions affect the municipal bond market over the past
six months?

A  1995 has been a much improved environment for municipal bonds. Lower
interest rates contributed to a nice rebound for municipal bond prices, in
sharp contrast to 1994. Combined with low inflation, real after-tax yields
for municipal bond investors were quite attractive.

Q  How did the Funds perform?

A  All five Keystone funds posted positive total returns for the six months
which ended September 30, 1995. Shares prices rose during the period and
paralleled the performance of the municipal bond market. The Funds continued
to provide shareholders with attractive tax-free income. Considering all the
talk about a flat tax in Congress, we were pleased with the Funds'
performance.

Q  What effect would a flat tax have on municipal bond investments?

A  Enactment of a flat tax would eliminate the tax advantage of municipal
bonds because the income they pay would no longer be tax-exempt. As a result,
states and local governments would lose an important source of inexpensive
financing.

Q  Do you believe a flat tax will be enacted?

A  No, we believe the enactment of a flat tax is highly unlikely. But,
discussions in Washington held back performance that would otherwise have
been even stronger for municipal bonds. We would not be surprised to see some
minor changes to the tax code, but we see significant hurdles to
implementation of a flat tax. On the national level, any decrease in tax
revenues would make it even more difficult to balance the federal budget. On
the local level, many state governments are already strained to pay for a
greater portion of federally mandated services, such as Medicaid. Eliminating
states' ability to issue tax-free bonds would make this problem even worse.
Because of this, we think passage of a flat tax is highly unlikely.

Q  What were the key components of your investment strategy?

A  Based on the yield curve (see chart), we concentrated on bonds with
20-year maturities because they provided yields close to those of 30-year
bonds but with less risk. We continued to focus on high quality bonds with
higher coupons to maximize tax-free income.We continued our emphasis on
"non-callable" bonds--bonds which cannot be called back by their issures and
repaid early--to increase the potential for price appreciation. We also
invested selectively in industrial development bonds to take advantage of
their higher yields.

Because the difference in yield between 20-year and 30-year bonds was small, we
emphasized 20 year bonds.

Source: Goldman Sachs
- --------------------------------------------------------------------

Q  What types of bonds do you favor in today's environment?

A  We are extremely selective about fund holdings and generally prefer bonds
rated A or better. We continue to emphasize high quality essential services
and general obligation bonds--bonds that we believe should do well in a slow
growth economy. We maintain core positions of relatively high coupon bonds to
generate strong income streams, and invest in a small percentage of lower
quality bonds for their high yields or price appreciation potential. We
always evaluate how a potential holding will fit with the existing
composition of each portfolio, and strive to build portfolios that are
diversified across credit sectors and maturities.

Q  What is your outlook for the municipal bond market?

A  We are cautiously positive on the market. The trend in rates is down,
inflation is low, the dollar is stronger against foreign currencies and the
economy seems to have adjusted to slower growth. While we will continue to
monitor Washington's discussions on a flat tax, we believe these are all
positive factors for municipal bond performance over the long term. We are
also watching other economic indicators performance over the long-term
direction of the economy which could have an impact on interest rates and
bond prices.

Q  Is this a good time for investors to buy tax free funds?

A  Yes, we believe it is. Municipal bond funds remain one of the few sources
of tax-free income for investors, and with inflation so low, real after-tax
returns are very attractive. Of course there is always risk associated with
investing, but our emphasis on high quality municipal bonds helps improve the
stability of the Funds' portfolios. We think the portfolios of Keystone State
Tax Free Fund will continue to offer investors a diversified, professionally
managed opportunity for income that is exempt from federal and state (and
city) taxes as applicable.(18)

Keystone State Tax Free Fund

   MUTUAL FUND--A company which combines the investment money of many people
whose financial goals are similar, and invests that money in a variety of
securities. A mutual fund allows the smaller investor the benefits of
diversification, professional management and constant supervision usually
available only to large investors.

   PORTFOLIO MANAGER--An investment professional who is responsible for
managing a portfolio's assets prudently and making appropriate investment
decisions, such as which securities to buy, hold and sell, based on the
investment objectives of the portfolio.

   STOCK--Equity or ownership interest in a corporation, which represents a
claim on the corporation's assets and earnings.

   BOND--Security issued by a government or corporation to those from whom it
has borrowed money. A bond usually promises to pay interest income to the
bondholder at regular intervals and to repay the entire amount borrowed at
maturity date.

   CONVERTIBLE SECURITY--A corporate security (usually preferred stock or
bonds) that is exchangeable for a set number of another security type
(usually common stocks) at a pre-stated price.

   MONEY MARKET FUND--A mutual fund whose assets are invested in a
diversified portfolio of short- term securities, including commercial paper,
bankers' acceptances, certificates of deposit and other short-term
instruments. The fund pays income which can fluctuate daily. Liquidity and
safety of principal are primary objectives.

   NET ASSET VALUE (NAV) PER SHARE--The value of one share of a mutual fund.
The NAV per share is determined by subtracting a fund's total liabilities
from its total assets, and dividing that amount by the number of fund shares
outstanding.

   DIVIDEND--A per share distribution of the income earned from the fund's
portfolio holdings. When a dividend distribution is made, the fund's net
asset value drops by the amount of the distribution because the distribution
is no longer considered part of the fund's assets.

   CAPITAL GAIN--The profit from the sale of securities, less any losses.
Capital gains are paid to fund shareholders on a per share basis. When a
capital gain distribution is made, the fund's net asset value drops by the
amount of the distribution because the distribution is no longer considered
part of the fund's assets.

   YIELD--The annualized rate of income as measured against the current net
asset value of fund shares.

   TOTAL RETURN--The change in value of a fund investment over a specified
period of time, taking into account the change in a fund's market price and
the reinvestment of all fund distributions.

   SHORT-TERM--An investment with a maturity of one year or less.

   LONG-TERM--An investment with a maturity of greater than one year.

   AVERAGE MATURITY--The average number of days until the notes, drafts,
acceptances, bonds or other debt instruments in a portfolio become due and
payable.

   OFFERING PRICE--The offering price of a share of a mutual fund is the
price at which the share is sold to the public.

Keystone State Tax Free Fund

NOTES TO FINANCIAL STATEMENTS
(Unaudited)

1. Significant Accounting Policies

Keystone State Tax Free Fund (formerly Keystone America State Tax Free Fund)
("FUND") was formed as a Massachusetts business trust on September 13, 1990.
Keystone Investment Management Company (formerly Keystone Custodian Funds,
Inc.) ("Keystone") is the Investment Adviser and Manager. The FUND currently
offers shares of five separate series evidencing interests in different
portfolios of securities: the Keystone Florida Tax Free Fund (formerly
Keystone America Florida Tax Free Fund) ("Florida Fund"), which was
established on September 19, 1990 and had no operations prior to December 27,
1990; the Keystone Massachusetts Tax Free Fund (formerly Keystone America
Massachusetts Tax Free Fund) ("Massachusetts Fund"), and the Keystone New
York Insured Tax Free Fund (formerly Keystone America New York Insured Tax
Free Fund) ("New York Fund"), which were established February 21, 1992 and
had no operations prior to February 4, 1994; the Keystone Pennsylvania Tax
Free Fund (formerly Keystone America Pennsylvania Tax Free Fund)
("Pennsylvania Fund"), which was established September 19, 1990 and had no
operations prior to December 27, 1990; and the Keystone Texas Tax Free Fund
(formerly Keystone America Texas Tax Free Fund) ("Texas Fund"), which was
established on February 21, 1992 and had no operations prior to March 2, 1992
(together the "Funds" and each individually a "Fund"). The FUND is registered
under the Investment Company Act of 1940 ("1940 Act") as an open-end
investment company and each of the Funds is registered as a nondiversified
fund.

   Each Fund currently offers three classes of shares. Class A shares are
sold subject to a maximum sales charge of 4.75% payable at the time of
purchase. Class B shares are sold subject to a contingent deferred sales
charge which varies depending on when shares were purchased and how long they
have been held. Class C shares are sold subject to a contingent deferred
sales charge payable upon redemption within one year of purchase, and
available only through dealers who have entered into special distribution
agreements with Keystone Investment Distributors Company ("KIDC") (formerly
Keystone Distributors, Inc.), the FUND's principal underwriter.

   Keystone is a wholly-owned subsidiary of Keystone Investments, Inc.
("KII") (formerly Keystone Group, Inc.), a Delaware corporation. KII is
privately owned by an investor group consisting of members of current and
former management of Keystone and its affiliates. 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 conformity with generally accepted accounting
principles.

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

<PAGE>

PAGE 53
- -----------------------------------------------------------------------------

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.

   Each Fund enters into currency and other financial futures contracts as a
hedge against changes in interest or currency exchange rates. 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 the Fund's taxable income. In
addition to market risk, the Fund is subject to the credit risk that the
other party will not complete the obligations of the contract.

B. When-issued or delayed delivery transactions arise when securities or
currencies are purchased or sold by a Fund with payment and delivery taking
place in the future in order to secure what is considered to be an
advantageous price and yield to the Fund at the time of entering into the
transaction. A separate account of liquid assets equal to the value of such
purchase commitments will be maintained until payment is made. When-issued
and delayed agreements are subject to risks from changes in value based upon
changes in the level of interest rates and other market factors, both before
and after delivery.

C. Securities transactions are accounted for no later than one business day
after the trade date. Realized gains and losses are recorded on the
identified cost basis. Interest income is recorded on the accrual basis.

D. Each Fund has qualified, and intends to qualify in the future, as a
regulated investment company under the Internal Revenue Code of 1986, as
amended ("Internal Revenue Code"). Thus, each Fund 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 tax-exempt interest portion of each dividend is declared uniformly based
on the ratio of each Fund's tax-exempt and taxable income for the entire
year. Each Fund intends to avoid excise tax liability by making the required
distributions under the Internal Revenue Code.

E. Organization expenses are being amortized to operations over a five-year
period on a straight-line basis. In the event any of the initial shares are
redeemed by any holder thereof during the five-year amortization period,
redemption proceeds will be reduced by any unamortized organization expenses
in the same proportion as the number of initial shares being redeemed bears
to the number of initial shares outstanding at the time of redemption.

2. Capital Share Transactions

The Trust agreement authorizes the issuance of an unlimited number of shares
of beneficial interest without par value. Transactions in shares of the FUND
were as follows:

   Each Fund bears some of the costs of selling its shares under a
Distribution Plan adopted with respect to its Class A, Class B, and Class C
shares pursuant to Rule 12b-1 under the 1940 Act.

   Each Class A Distribution Plan provides for payments which are currently
limited to 0.15% annually of the average daily net asset value of Class A
shares to pay expenses of the distribution of Class A shares. Amounts paid by
each Fund to KIDC under the Class A Distribution Plan are currently used to
pay others such as dealers, service fees at an annual rate of 0.15% of the
average net asset value of Class A shares maintained by such others and
remaining outstanding on the books of the Funds for specified periods.

   Each Class B Distribution Plan provides for payments at an annual rate of
0.90% of the average daily net asset value of Class B shares to pay expenses
of the distribution of Class B shares. Amounts paid by each Fund under the
Class B Distribution Plan are currently used to pay others (dealers) (i) a
commission at the time of purchase normally equal to 4.00% of the price paid
for each Class B share sold plus the first year's service fee in advance in
the amount of 0.15% of the price paid for each Class B share sold. Beginning
approximately 12 months after the purchase of a Class B share, the dealer or
other party will receive service fees at an annual rate of 0.15% of the
average daily net asset value of each Class B share maintained by such others
outstanding on the Fund's books for specified periods. A contingent deferred
sales charge will be imposed, if applicable, on Class B shares purchased
after June 1, 1995 at rates ranging from a maximum of 5.00% of amounts
redeemed during the first twelve months following the date of purchase to
1.00% of amounts redeemed during the sixth twelve-month period following the
date of purchase. Class B shares purchased on or after June 1, 1995 that have
been outstanding for eight years following the month of purchase will
automatically convert to Class A shares without a front end sales charge or
exchange fee. Class B shares purchased prior to June 1, 1995 will retain
their existing conversion rights.

   Each Class C Distribution Plan provides for payments at an annual rate of
up to 0.90% of the average daily net asset value of Class C shares to pay
expenses

of the distribution of Class C shares. Amounts paid by each Fund under the
Class C Distribution Plan are currently used to pay others (dealers) a
commission at the time of purchase normally equal to 0.75% of the price paid
for each share sold plus the first year's service fee in advance in the
amount of 0.15% of the price paid for each Class C share. Beginning
approximately 15 months after purchase, the dealer or other party will
receive a commission at an annual rate of 0.75% (subject to applicable
limitations imposed by the rules of the National Association of Securities
Dealers, Inc. ("NASD rule") plus service fees at an annual rate of 0.15%,
respectively, of the average net asset value of each Class C share sold by
such others and remaining outstanding on the books of the Funds for specified
periods.

   Each of the Distribution Plans may be terminated at any time by vote of
the Independent Trustees or by vote of a majority of the outstanding voting
shares of the respective class. However, after the termination of any of the
Distribution Plans, at the discretion of the Board of Trustees, payments to
KIDC may continue as compensation for its services which had been earned
while the distribution Plan was in effect.

   For the six months ended September 30, 1995, the Florida Fund paid KIDC
$30,113, $238,600 and $55,449, the Massachusetts Fund paid KIDC $1,244,
$29,762 and $9,042, the New York Fund paid KIDC $2,721, $62,533, and $11,527,
the Pennsylvania Fund paid KIDC $22,965, $149,952 and $43,690, and the Texas
Fund paid KIDC $1,202, $11,946 and $1,248, respectively, pursuant to each
Fund's Class A, Class B, and Class C Distribution Plans.

   Under a Rule of the NASD, the maximum uncollected amounts for which KIDC
may seek payment from the FUND under its Class B Distribution Plans are
$3,119,763, $382,667, $788,515, $1,920,879, and $139,964 for shares purchased
prior to June 1, 1995 and $229,596, $47,184, $159,081, $265,961 and $93,126
for shares purchased after June 1, 1995, respectively, for the Florida Fund,
the Massachusetts Fund, the New York Fund, the Pennsylvania Fund and the
Texas Fund as of September 30, 1995. The maximum uncollected amounts for
which KIDC may seek payment from the FUND under its Class C Distribution
Plans are $1,254,939, $121,460, $187,290, $772,302, and $63,746,
respectively, for the Florida Fund, the Massachusetts Fund, the New York
Fund, the Pennsylvania Fund and the Texas Fund as of September 30, 1995.

4. Investment Management and Transactions with Affiliates

Under the terms of the Investment Management Agreement between Keystone and
the FUND, dated November 29, 1990, Keystone provides investment management
and administrative services to the FUND and its Funds. In return, Keystone is
paid a management fee computed and paid daily. The management fee is
calculated by applying percentage rates, which start at 0.55% and decline, as
net assets increase, to 0.25% per annum, to the net asset value of each Fund.

   During the six months ended September 30, 1995, the Florida Fund,
Massachusetts Fund, New York Fund, Pennsylvania Fund and Texas Fund paid or
accrued to Keystone investment management and administrative services fees of
$277,231, $29,992, $55,234, $196,952 and $12,483, respectively, which
represented 0.52%, 0.55%, 0.55%, 0.53%, and 0.55%, respectively, of the
average net assets of the Funds on an annualized basis.

   During the six months ended September 30, 1995, the Florida Fund,
Massachusetts Fund, New York Fund, Pennsylvania Fund and Texas Fund paid or
accrued to KII $9,273, $9,874, $9,563, $9,934 and $9,816, respectively, for
certain accounting and to KIRC $59,925, $9,401, $14,666, $55,494, and $2,570,
respectively, for transfer agent fees.

   Keystone has voluntarily agreed to limit all expenses incurred including
management fee of the Class A Shares of the Florida Fund, the Pennsylvania
Fund and the Texas Fund to 0.75% of average daily net assets and has limited
annual expenses of the Class B Shares and Class C Shares to 1.50% of average
daily net asset value.

   Keystone voluntarily limited the expenses, including the management fee,
of the Class A Shares of the Massachusetts Fund and the New York Fund to
0.35% until August 15, 1994, after which the expense limitation was increased
by 0.10% every three months until May 15, 1995 since which date expenses were
limited to 0.75% until December 31, 1995. Expenses of Class B Shares and
Class C Shares of those Funds were limited to 1.10% until August 15, 1994,
after which the expense limitations were similarly increased until May 15,
1995 since which date expenses were limited to 1.50% until December 31, 1995.
Keystone will not be required to make such reimbursement to an extent which
would result in a Fund's inability to qualify as a regulated investment
company under the provisions of the Internal Revenue Code. In accordance with
this voluntary expense limitation, Keystone reimbursed the Florida Fund, the
Massachusetts Fund, the New York Fund, the Pennsylvania Fund and the Texas
Fund (i) $33,827, $11,143, $10,401, $38,806 and $14,391, respectively, with
respect to each Fund's

<PAGE>

PAGE 59
- -----------------------------------------------------------------------------

Class A Shares, (ii) $59,703, $33,524, $39,404, $51,176 and $22,732,
respectively, with respect to each Fund's Class B Shares; and (iii) $13,932,
$10,266, $7,476, $14,976 and $2,484, respectively, with respect to each
Fund's Class C Shares. Keystone does not intend to seek repayment of these
amounts.

   Certain officers and/or Directors of Keystone are also officers and/or
Trustees of the FUND. Officers of Keystone and affiliated Trustees receive no
compensation directly from the FUND. Currently, the Independent Trustees of
the FUND receive no compensation for their services.

5. Distributions to Shareholders

Each Fund intends to declare dividends from net investment income daily and
distribute to its shareholders such dividends monthly and to declare and
distribute all net realized long-term capital gains, if any, at least
annually. Distributions are determined in accordance with income tax
regulations. Distributions from tax basis net investment income and net
capital gains can exceed book basis net investment income and net capital
gains.
