DEAR SHAREHOLDERS,
 
The third quarter of 1998 ended on a mildly positive note with the Federal
Reserve Board (the Fed) reducing interest rates by 1/4 of a point to 5.25
percent. While some investors were disappointed by the small size of the
adjustment, it nevertheless provided a moment of relief after several stormy
months. Economic and political instability in Russia, terrorist bombings and
U.S. retaliation overseas, lingering effects of the "contagion" in Asia, not to
mention weak corporate profits and political scandal in the United States were
responsible for considerable uncertainty and market volatility. A series of
market dips and drops continued to fuel the debate about whether we would
finally see the end of our long-running bull market -- or even plummet into a
recession.
 
     The Fed's mid-September bank credit survey indicated that domestic banks
are tightening credit standards for both large and small borrowers. This
suggests a reduction in the supply of credit going forward with subsequent
negative impacts on employment growth and capital spending. In this sense, there
is the beginning of a credit crunch starting in U.S. bank credit markets.
 
     But investors should find comfort in the fact that economic fundamentals
continue to favor financial assets in the U.S. -- particularly Treasury bonds.
In a nutshell, the nation's economy remains strong despite its slowdown in the
second half of the year. Short-term interest rates are expected to remain low
for the remainder of the year. There are no major tax or regulatory threats
waiting in the wings. And our economy continues to draw investors from around
the world, although perhaps not as fervently as last year.
 
     The nation's gross domestic product (GDP), which represents the total value
of all goods and services produced within the U.S. economy, is expected to have
grown at an annualized rate of 2 percent in the third quarter of 1998. Faster
growth can be attributed to several one-time factors, including a domestic
correction in inventory levels and the end of the General Motors strike.

     Real capital spending and employment growth have remained solid. Consumer
confidence remains fairly high. Home sales remain robust. Economic policy
continues to support the nation's fiscal budget surplus projection of $65
billion.
 
     As far as inflation goes, there are two tales to be told. Prices for
consumer goods, as measured by the consumer price index (CPI), are steady.
Compare this to prices for services, which have risen between 2.5 and 3.5
percent. For investors, this difference in pricing flexibility translates into a
difference in profit expectations. Profits of domestic service firms should be
much stronger than commodity producers dependent on export markets.
 
     Across the Atlantic, Europe's economy appears to be growing at an even pace
as the region progresses toward the Economic and Monetary Union (EMU) slated for
January 1, 1999. One effect of the union may be a slight rise in short-term
interest rates in Europe -- not because there will be an overt change in policy,
but simply because of the convergence of some very disparate interest rates. The
average rate will likely be higher than the relatively attractive rate the
German Central Bank currently offers, for example.
 
     In Asia, which has been making headlines around the world for more than a
year now, the latest news is from Japan, which recently installed a new prime
minister as well as a new finance minister. Much discussion will be focused on
changes in Japan's economic policy, particularly in terms of taxation and
banking reform -- and patience is in order. Most of the changes in taxation will
impact Japan in the first half of 1999. But as far as banking reform goes, those
of us familiar with bank reform in the U.S. know that this will be a two- to
five-year process. Certainly, investors are looking to Japan to spark recovery
for Asia as a whole, which continues to suffer from the "contagion" of low
currency values, seriously reduced consumer spending and general economic
malaise.
 
     Indeed, while its full effects remain to be seen -- and felt -- by the
majority of American businesses and individuals, the Asian economic crisis has
contributed to the general uncertainty of the emotion-driven U.S. markets.
Whether it's an economic crisis abroad or political scandal at home, current
events move the investors who move the markets.

  One might conclude that, as a result of 1998's slow corporate profit growth
and turmoil in Russia and Asia, the psychology of the markets is
shifting -- even some of Wall Street's most resolute bulls appear to be
reconsidering their long-held convictions. But with the economy's strong
fundamentals in place, the outlook for a bear market is premature. In any case,
prudent investors are wise to watch for the following economic warning signs:
inflation in the form of rising wages and/or prices; residual fallout from Asia,
which could appear in the form of reduced sales and earnings for American
businesses; and a continued widening of our trade deficit, an imbalance caused
by heightened American demand for foreign goods and services. In the months to
come, investors are likely to maintain their bias in favor of investments that
have historically been considered more conservative: larger capitalization
stocks, U.S. Treasuries and only the highest-grade corporate bonds.
 
  Thank you for your continued support. We appreciate the opportunity to serve
your investment needs.
 
Sincerely,

MUNICIPAL BONDS IN GENERAL AND THE KEMPER STATE TAX-FREE INCOME SERIES IN
PARTICULAR PERFORMED WELL DURING THE PAST TWELVE MONTHS. BELOW, CO-PORTFOLIO
MANAGER CHRIS MIER DISCUSSES THE FORCES THAT AFFECTED THE MUNICIPAL BOND MARKET,
AND HOW THE FUNDS WERE POSITIONED IN RESPONSE.
 
Q     CHRIS, THE LAST YEAR APPEARS TO HAVE BEEN A PERIOD OF UNUSUALLY STRONG
PERFORMANCE FOR MUNICIPAL BONDS. IN FACT, THE AVERAGE MUNICIPAL BOND FUND
RETURNED 8.20 PERCENT AS MEASURED BY THE LIPPER GENERAL MUNICIPAL DEBT CATEGORY,
WHICH WAS EVEN BETTER THAN THE STOCK MARKET'S 8.12 PERCENT AS MEASURED BY THE
S&P 500*. WHAT FACTORS WERE RESPONSIBLE FOR THIS PERFORMANCE?
 
A     The last year was somewhat unusual because factors outside the U.S. played
a significant role in the performance of municipal bonds. The market was
impacted first by developments in Asia, then in Latin America and Russia.
 
      Before the fiscal year began, news about potential economic and currency
problems in Asian countries had been circulating for a while. Investors began to
realize that the outsized growth experienced by these countries -- particularly
Hong Kong, Thailand, Malaysia and Indonesia -- was fueled largely by intense
speculation by investors worldwide. This support reversed itself in the summer
of 1997 and came to a head in October as the Hong Kong stock market imploded. A
series of foreign currency devaluations followed.
 
      However, the problems abroad led to strong performance by government bonds
here in the U.S. Investors opted for the relatively safe haven of Treasuries,
and demand drove Treasury bond prices sharply higher. At the same time,
investors expected cheaper foreign goods to put a damper on U.S. inflation, and
lower exports to impede U.S. economic growth. This suggested lower interest
rates in the future, a positive for bonds.
 
      In 1998, Latin American countries also started to experience problems, and
most recently, Russia effectively devalued the ruble. This continuing turmoil
further increased demand for U.S. government bonds, and the result was that
Treasuries staged a powerful rally in August as the fiscal year drew to a close.

  CONSIDERED REPRESENTATIVE OF THE U.S. STOCK MARKET.
 
Q     DID MUNICIPAL BONDS ENJOY THE SAME KIND OF RALLY?
 
A     To an extent, yes. But one factor that impeded the muni market's progress
was very heavy issuance. Lower interest rates increased the supply of municipal
bonds in two ways:
 
1)    New issues -- new bond offerings flooded the market as local governments
      tried to capitalize on low interest rates to beef up infrastructure such
      as highways and water/sewer projects.
 
2)    Refinancing bonds -- when rates decline, municipal issuers look to 
      refinance their debt, just like private homeowners refinance their
      mortgages when rates fall. So municipal governments issued new
      lower-yielding bonds to replace the higher-yielding ones.
 
      If the current rate of issuance keeps up, 1998 will be a record year in
terms of municipal bond issuance.
 
      Much of this supply has been sopped up by hedge funds and "crossover"
buyers, primarily

PERFORMANCE UPDATE 


investors who usually buy taxable bonds, but who have recognized the outstanding
value in municipals. Such "non-traditional" buyers have helped offset the glut
of issuance.
 
Q     HOW DID YOU RESPOND TO THE MARKET'S CONDITIONS?
 
A     Primarily, we adjusted the duration of the funds to help position them to
perform. Duration, as you may know, is an indication of a portfolio's
sensitivity to changes in interest rates. If you expect the market to rally and
interest rates go down, you want to lengthen duration to help the funds
participate as much as possible. If you expect interest rates to trend up, you
want to shorten duration to help lessen the negative effects.
 
      As the fiscal year began, we had been keeping the duration of the funds
neutral. That continued through October, when global stock markets went into a
tailspin. After that, we began to lengthen duration because we expected a flight
to quality to increase demand for government bonds and to force interest rates
lower.
 
      In January, market yields appeared to be near a low, so we moved back to a
neutral stance until late into the summer of 1998. During the first half of the
year, the domestic economy still appeared strong, and the Federal Reserve's
policy reflected a bias to keep interest rates stable to help guard against
inflation. But in June, investors began to see signs that U.S. economic growth
was slowing and that troubles abroad would likely impede strong domestic growth.
So we lengthened durations of the funds through July and August, which put us in
a position to benefit when the market rallied strongly in August.
 
      Overall, we did well adjusting duration in advance of the market's moves,
which helped us post good returns despite an overabundance of supply. In fact,
all four funds (Class A shares, unadjusted for any sales charge) covered in this
report significantly outpaced their Lipper category average for the year. (See
page 2 for one-year Total Returns).
 
Q     YOU MENTIONED THAT CROSSOVER BUYERS HAVE BEGUN TO "RECOGNIZE THE
OUTSTANDING VALUE IN MUNICIPALS." WHAT OUTSTANDING VALUE DO YOU MEAN?
 
A     Municipal bonds offer attractive value right now for several reasons.
First, the heavy supply of municipal bonds has kept yields from declining as
fast as Treasuries. Thus, at the end of August, municipal bonds offered nearly
the same yield as Treasuries. Second, that relatively high yield doesn't even
take into account the tax advantage. And third, because municipal bonds give you
a better real return, that is, what you have left after taking into account the
effects of inflation.
 
      Finally, municipal bonds are not currently experiencing some of the credit
problems other markets -- such as those for corporate bonds or emerging markets
bonds -- are facing.
 
Q     SO YOUR OUTLOOK FOR THE MUNI MARKET IS PRETTY BRIGHT AT THIS POINT.
 
A     We're very optimistic about the prospects for municipal bonds. Municipal
bonds not only performed well during the year, they still represent an extremely
attractive investment. Their value versus other fixed income securities is only
one reason. There are others. For example, the strong economy and low interest
rates have increased tax revenues and allowed municipal government to strengthen
their balance sheets. In our experience, credit quality has never been better
for many states.
 
      In addition, the Federal Reserve may lower interest rates in the near
future if the U.S. economy appears to be stalling. That would mean lower rates
for money market fund investors, and investors who currently have billions of
dollars in assets on the sidelines may recognize that munis appear to be the
best value in the fixed-income market right now. Demand from such investors
could spark a significant rally.
 
      And finally, the volatility in other markets over the last 12 months has
shown the importance of diversification. Because the stock market has advanced
strongly over the last three years, many investors' portfolios may have become a
little stock-heavy. They may want to take some money out of stocks and put it in
bonds to rebalance their portfolios, and muni bonds right now may be a smart
choice for many such investors.

Past performance is not a guarantee of future results. Investment returns and
principal values will fluctuate so that shares when redeemed may be worth more
or less than original cost.
 
*   Average annual total return and total return measure net investment income 
    and capital gain or loss from portfolio investments over the periods
    specified, assuming reinvestment of dividends and, where indicated,
    adjustment for the maximum sales charge. The maximum sales charge for Class
    A shares is 4.5%. For Class B shares, the maximum contingent deferred sales
    charge is 4%. Class C shares have no sales adjustment, but redemptions
    within one year of purchase may be subject to a contingent deferred sales
    charge of 1%. Share classes invest in the same underlying portfolio. Average
    annual total return reflects annualized change while total return reflects
    aggregate change. During the periods noted, securities prices fluctuated.
 
(1) Performance includes reinvestment of dividends and adjustment for the
    maximum sales charge for Class A shares and the contingent deferred sales
    charge in effect at the end of the period for Class B shares. In comparing
    the Kemper State Tax-Free Income Funds to the Lehman Brothers Municipal Bond
    Index, you should note that the funds' performance reflects the maximum
    sales charges, while no such charges are reflected in the performance of the
    index.
 
+   The Lehman Brothers Municipal Bond Index includes approximately 15,000
    bonds. To be included in the index a municipal bond must meet the following
    criteria: a minimum credit rating of BBB, have been issued as a part of an
    issue of at least $50 million, have been issued within the last 5 years, and
    have a maturity of at least 2 years. Bonds subject to Alternative Minimum
    Tax (AMT), variable rate bonds and zero coupon bonds are excluded from the
    index. Source is Towers Data Systems.
 
++  The Consumer Price Index is a statistical measure of change, over time,
    in the prices of goods and services in major expenditure groups for all
    urban consumers. It is generally considered to be a measure of inflation.
    Source is Towers Data Systems.

Past performance is not a guarantee of future results. Investment returns and
principal values will fluctuate so that shares when redeemed may be worth more
or less than original cost.
 
*   Average annual total return and total return measure net investment income
    and capital gain or loss from portfolio investments over the periods
    specified, assuming reinvestment of dividends and, where indicated,
    adjustment for the maximum sales charge. The maximum sales charge for Class
    A shares is 4.5%. For Class B shares, the maximum contingent deferred sales
    charge is 4%. Class C shares have no sales adjustment, but redemptions
    within one year of purchase may be subject to a contingent deferred sales
    charge of 1%. Share classes invest in the same underlying portfolio. Average
    annual total return reflects annualized change while total return reflects
    aggregate change. During the periods noted, securities prices fluctuated.
 
(1) Performance includes reinvestment of dividends and adjustment for the
    maximum sales charge for Class A shares and the contingent deferred sales
    charge in effect at the end of the period for Class B shares. In comparing
    the Kemper State Tax-Free Income Funds to the Lehman Brothers Municipal Bond
    Index, you should note that the funds' performance reflects the maximum
    sales charges, while no such charges are reflected in the performance of the
    index.
 
+   The Lehman Brothers Municipal Bond Index includes approximately 15,000
    bonds. To be included in the index a municipal bond must meet the following
    criteria: a minimum credit rating of BBB, have been issued as a part of an
    issue of at least $50 million, have been issued within the last 5 years, and
    have a maturity of at least 2 years. Bonds subject to Alternative Minimum
    Tax (AMT), variable rate bonds and zero coupon bonds are excluded from the
    index. Source is Towers Data Systems.
 
++  The Consumer Price Index is a statistical measure of change, over time, in
    the prices of goods and services in major expenditure groups for all urban
    consumers. It is generally considered to be a measure of inflation. Source
    is Towers Data Systems.

Past performance is not a guarantee of future results. Investment returns 
and principal values will fluctuate so that shares when redeemed may be
worth more or less than original cost.
 
 *   Average annual total return and total return measure net investment income 
     and capital gain or loss from portfolio investments over the periods
     specified, assuming reinvestment of dividends and, where indicated,
     adjustment for the maximum sales charge. The maximum sales charge for Class
     A shares is 4.5%. For Class B shares, the maximum contingent deferred sales
     charge is 4%. Class C shares have no sales adjustment, but redemptions
     within one year of purchase may be subject to a contingent deferred sales
     charge of 1%. Share classes invest in the same underlying portfolio.
     Average annual total return reflects annualized change while total return
     reflects aggregate change. During the periods noted, securities prices
     fluctuated.
 
 (1) Performance includes reinvestment of dividends and adjustment for the
     maximum sales charge for Class A shares and the contingent deferred sales
     charge in effect at the end of the period for Class B shares. In comparing
     the Kemper State Tax-Free Income Funds to the Lehman Brothers Municipal
     Bond Index, you should note that the funds' performance reflects the
     maximum sales charges, while no such charges are reflected in the
     performance of the index.
 
 +   The Lehman Brothers Municipal Bond Index includes approximately 15,000
     bonds. To be included in the index a municipal bond must meet the following
     criteria: a minimum credit rating of BBB, have been issued as a part of an
     issue of at least $50 million, have been issued within the last 5 years,
     and have a maturity of at least 2 years. Bonds subject to Alternative
     Minimum Tax (AMT), variable rate bonds and zero coupon bonds are excluded
     from the index. Source is Towers Data Systems.
 
++   The Consumer Price Index is a statistical measure of change, over time, in
     the prices of goods and services in major expenditure groups for all urban
     consumers. It is generally considered to be a measure of inflation. Source
     is Towers Data Systems.

Past performance is not a guarantee of
future results. Investment returns and
principal values will fluctuate so that
shares when redeemed may be worth more
or less than original cost.
 
 *Average annual total return and total
  return measure net investment income
  and capital gain or loss from
  portfolio investments over the periods
  specified, assuming reinvestment of
  dividends and, where indicated,
  adjustment for the maximum sales
  charge. The maximum sales charge for
  Class A shares is 4.5%. For Class B
  shares, the maximum contingent
  deferred sales charge is 4%. Class C
  shares have no sales adjustment, but
  redemptions within one year of
  purchase may be subject to a
  contingent deferred sales charge of
  1%. Share classes invest in the same
  underlying portfolio. Average annual
  total return reflects annualized
  change while total return reflects
  aggregate change. During the periods
  noted, the securities prices
  fluctuated.
 
 (1)Performance includes reinvestment of
    dividends and adjustment for the
    maximum sales charge for Class A
    shares and the contingent deferred
    sales charge in effect at the end of
    the period for Class B shares. In
    comparing the Kemper State Tax-Free
    Income Funds to the Lehman Brothers
    Municipal Bond Index, you should
    note that the funds' performance
    reflects the maximum sales charges,
    while no such charges are reflected
    in the performance of the index.
 
 +The Lehman Brothers Municipal Bond
  Index includes approximately 15,000
  bonds. To be included in the index a
  municipal bond must meet the following
  criteria: a minimum credit rating of
  BBB, have been issued as a part of an
  issue of at least $50 million, have
  been issued within the last 5 years,
  and have a maturity of at least 2
  years. Bonds subject to Alternative
  Minimum Tax (AMT), variable rate bonds
  and zero coupon bonds are excluded
  from the index. Source is Towers Data
  Systems.
 
++The Consumer Price Index is a
  statistical measure of change, over
  time, in the prices of goods and
  services in major expenditure groups
  for all urban consumers. It is
  generally considered to be a measure
  of inflation. Source is Towers Data
  Systems.

REPORT OF INDEPENDENT AUDITORS

THE BOARD OF TRUSTEES AND SHAREHOLDERS
KEMPER STATE TAX-FREE INCOME SERIES
 
  We have audited the accompanying statement of assets and liabilities,
including the portfolios of investments, of Kemper California Tax-Free Income
Fund, Kemper Michigan Tax-Free Income Fund, Kemper Ohio Tax-Free Income Fund,
and Kemper Texas Tax-Free Income Fund, four of the eight investment portfolios
comprising Kemper State Tax-Free Income Series (the Trust), as of August 31,
1998, the related statements of operations for the year then ended and changes
in net assets for each of the two years in the period then ended and the
financial highlights for each of the fiscal periods since 1994. These financial
statements and financial highlights are the responsibility of the Trust's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of investments owned as of
August 31, 1998, by correspondence with the custodian. 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 each
of the above mentioned Funds of the Kemper State Tax-Free Income Series at
August 31, 1998, the results of their operations for the year then ended, the
changes in their net assets for each of the two years in the period then ended,
and the financial highlights for each of the fiscal periods since 1994, in
conformity with generally accepted accounting principles.

     DESCRIPTION OF THE
     FUNDS                   Kemper California Tax-Free Income Fund, Kemper
                             Michigan Tax-Free Income Fund, Kemper Ohio Tax-Free
                             Income Fund and Kemper Texas Tax-Free Income Fund
                             (collectively the Funds) are four of eight
                             investment portfolios comprising the Kemper State
                             Tax-Free Income Series (the Trust). The remaining
                             portfolios are Kemper Florida, Kemper New Jersey,
                             Kemper New York and Kemper Pennsylvania Tax-Free
                             Income Funds. The Trust is an open-end management
                             investment company organized as a business trust
                             under the laws of Massachusetts.
 
                             Each Fund offers three classes of shares. Class A
                             shares are sold to investors subject to an initial
                             sales charge. Class B shares are sold without an
                             initial sales charge but are subject to higher
                             ongoing expenses than Class A shares and a
                             contingent deferred sales charge payable upon
                             certain redemptions. Class B shares automatically
                             convert to Class A shares six years after issuance.
                             Class C shares are sold without an initial sales
                             charge but are subject to higher ongoing expenses
                             than Class A shares and a contingent deferred sales
                             charge payable upon certain redemptions within one
                             year of purchase. Class C shares do not convert
                             into another class. Differences in class expenses
                             will result in the payment of different per share
                             income dividends by class. Each share of a Fund has
                             equal rights with respect to voting, dividends and
                             assets, subject to class specific preferences.

     SIGNIFICANT
     ACCOUNTING POLICIES     INVESTMENT VALUATION. Investments are stated at
                             value. Fixed income securities are valued by using
                             market quotations, or independent pricing services
                             that use prices provided by market makers or
                             estimates of market values obtained from yield data
                             relating to instruments or securities with similar
                             characteristics. Financial futures and options are
                             valued at the settlement price established each day
                             by the board of trade or exchange on which they are
                             traded. Over-the-counter traded options are valued
                             based upon prices provided by market makers. Other
                             securities and assets are valued at fair value as
                             determined in good faith by the Board of Trustees.
 
                             INVESTMENT TRANSACTIONS AND INVESTMENT
                             INCOME. Investment transactions are accounted for
                             on the trade date. Interest income is recorded on
                             the accrual basis and includes premium and original
                             issue discount amortization on fixed income
                             securities. Realized gains and losses from
                             investment transactions are reported on an
                             identified cost basis.
 
                             EXPENSES. Expenses arising in connection with a
                             specific Fund are allocated to that Fund. Other
                             Trust expenses are allocated among the Funds in
                             proportion to their relative net assets.
 
                             FUND SHARE VALUATION. Fund shares are sold and
                             redeemed on a continuous basis at net asset value
                             (plus an initial sales charge on most sales of
                             Class A shares). Proceeds payable on redemption of
                             Class B and Class C shares will be reduced by the
                             amount of any applicable contingent deferred sales
                             charge. On each day the New York Stock Exchange is
                             open for trading, the net asset value per share is
                             determined as of the close of the Exchange. The net
                             asset value per share is determined separately for
                             each class by dividing the Fund's net assets
                             attributable to that class by the number of shares
                             of the class outstanding.
 
                             FEDERAL INCOME TAXES. Each Fund's policy is to
                             comply with the requirements of the Internal
                             Revenue Code, as amended, which are applicable to
                             regulated investment companies, and to distribute
                             all of its taxable income to its

 NOTES TO FINANCIAL STATEMENTS

                             shareholders. Accordingly, each Fund paid no
                             federal income taxes and no federal income tax
                             provision was required.
 
                             DIVIDENDS TO SHAREHOLDERS. Each Fund declares and
                             records a daily dividend equal to its net
                             investment income for that day, to holders of
                             shares for which payment has been received. Income
                             dividends are distributed monthly. Net realized
                             capital gains, if any, are distributed at least
                             annually. Dividends are determined in accordance
                             with income tax principles which may treat certain
                             transactions differently from generally accepted
                             accounting principles.

     TRANSACTIONS
     WITH AFFILIATES         MANAGEMENT AGREEMENT. Each Fund has a management

                             assets in excess of $12.5 billion. Management fees
                             incurred for the year ended August 31, 1998 are as

                             For the year ended August 31, 1998, Scudder Kemper
                             has agreed to waive a portion of its management fee
                             and to absorb certain operating expenses of the
                             Michigan Fund. Under this arrangement, Scudder
                             Kemper waived and absorbed expenses of $9,000 for
                             the year ended August 31, 1998.
 
                             ZURICH/B.A.T MERGER. On September 7, 1998, Zurich
                             Insurance Company (Zurich), majority owner of
                             Scudder Kemper, entered into an agreement with
                             B.A.T Industries p.l.c. (B.A.T) pursuant to which
                             the financial services businesses of B.A.T were
                             combined with Zurich's businesses to form a new
                             global insurance and financial services company
                             known as Zurich Financial Services. Upon
                             consummation of the transaction, each Fund's
                             investment management agreement with Scudder Kemper
                             was deemed to have been assigned and, therefore,
                             terminated. The Board of Trustees of each Fund has
                             approved new investment management agreements with
                             Scudder Kemper, which are substantially identical
                             to the former investment management agreements,
                             except for the dates of execution and termination.
                             The Board of Trustees of each Fund will seek
                             shareholder approval of the new investment
                             management agreements through a proxy solicitation
                             that is currently scheduled to conclude in mid-
                             December.
 
                             UNDERWRITING AND DISTRIBUTION SERVICES AGREEMENT.
                             The Trust has an underwriting and distribution
                             services agreement with Kemper Distributors, Inc.
                             (KDI). Underwriting commissions paid in connection
                             with the distribution of each Fund's Class A shares
                             for the year ended August 31, 1998 are as follows:
