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.

   Class A shares were introduced on December 28, 1990. Performance is 
reported at the current maximum front-end sales charge of 4.75%. 

   Class B shares were introduced 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 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

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.

   Class A, Class B, and Class C shares were introduced on February 4, 1994. 

   Class A share performance is reported at the current maximum front-end 
sales charge of 4.75%. 

   Class B 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 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.

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 
than expected

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.

(11) For investors in certain tax situations, a portion of income may be 
     subject to the federal alternative minimum tax (AMT). 
(12) Where Standard & Poor's ratings were not available, we have used ratings 
     from Moody's Investor Service, Inc., Fitch Investors' Service, Inc., or 
     ratings assigned by another nationally recognized statistical rating

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.

   Class B shares were introduced 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 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.

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.

                             but more risk.

Because the difference in yield between 20-year and 30-year bonds was small, we
emphasized 20 year bonds.

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,

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,

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

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.
