o A resilient domestic economy and low inflation have been good for U.S. bonds
of all kinds.

o Lower borrowing costs have caused states and municipalities to rush to finance
new projects and refinance existing debt at lower rates. As a result, the supply
of municipal bonds for the first half of 1998 was relatively high.

o Housing projects in both Pennsylvania and Guam, a U.S. territory whose
municipal bonds are tax-exempt for residents of all states, represented
attractive investment opportunities.

 Dear shareholder,

President
Oppenheimer
Pennsylvania
Municipal Fund

The performance of the financial markets over the past several months could be
viewed as "A Tale of Two Markets." Until mid-July, the excitement surrounding
the stock market's continued ascent to new record highs overshadowed the
favorable economic environment that existed for bonds: low inflation and
declining interest rates. However, since that time, stocks have declined sharply
amid heightened volatility. Yet, the bond market remains poised to benefit from
the same positive economic conditions that existed earlier in the year.

      Why have stocks faltered lately? The financial crises in Asia and Russia
have negatively affected the earnings of some large U.S. corporations and have
contributed to a slow-down in U.S. economic growth. Although slower economic
growth has been negative for stocks, it should not adversely impact bonds.
That's because slower economic growth generally means fewer inflationary
pressures and less likelihood that interest rates will rise.

      What should you do during this period of relative uncertainty? If you have
well-defined long-term financial goals and an investment strategy designed to
achieve them, we encourage you to stay the course. However, if you feel your
financial plan is out-of-date or incomplete, now is the time to make
improvements. The best way to cope with short-term volatility is to adhere to a
long-term plan that contains proven strategies, such as diversification among
various financial markets, geographic regions, investment styles and individual
securities. A long-term plan will give you the focus and perspective you need to
put short-term volatility in its proper context.

      As longstanding advocates of financial planning, we have been encouraged
by our shareholders' rational responses to the latest market events. Many of you
tell us that you have a long-term strategy in place, which includes diversifying
your investment portfolio among a number of different asset classes in
accordance with your tolerance for risk. At OppenheimerFunds, our portfolio
management teams include seasoned professionals who have encountered extreme
market volatility in the past, giving them the per spective required to address
risks and take advantage of opportunities in turbulent markets. In our view,
having a well-defined set of financial goals, a disciplined long-term strategy
and the help of experienced investment professionals are all fundamental parts
of The Right Way to Invest.

Sincerely,


/s/ Bridget A. Macaskill

 An interview with your Fund's manager
- --------------------------------------------------------------------------------

"For example, we've found opportunities in Pennsylvania's healthcare
industry..."

How has Oppenheimer Pennsylvania Municipal Fund performed over the past 12
months?

The Fund's Class Ashares provided an average annual total return, without
deducting sales charges, of 4.99% for the one-year period that ended July 31,
1998.(1) These results reflect both income payments and capital appreciation of
the tax-exempt fixed-income securities in which the Fund invests.

How have positive U.S. economic conditions over the past year affected
Pennsylvania's municipal bonds?

A resilient U.S. economy and low inflation have been good for domestic bonds of
all kinds, including those from Pennsylvania issuers. The state and national
economies have continued to expand, despite concerns that the Asian financial
crisis might cause growth to slow. So far, consumers appear to have picked up
any slack created by weak demand from Asia, spending freely for major purchases
such as cars, boats and second homes. Yet, inflation has remained at
historically low levels. Even the nation's record-high employment has failed to
rekindle inflationary pressures.

      These economic influences, which have prevailed in Pennsylvania as well as
the rest of the country, have allowed longer-term interest rates to move lower
relative to short-term interest rates. Because bond prices rise when interest
rates decline, most sectors of the U.S. bond market provided above-average total
returns over the past year. However, taxable bonds, such as U.S. Treasury
securities, generally provided higher returns than tax-exempt bonds.

Why did taxable bonds outperform municipal bonds?

It's a matter of supply and demand. When the supply of municipal bonds issued is
high relative to demand from investors, higher yields may be required to attract
a limited number of investors. Conversely, when supply is low, issuers can offer
bonds with lower yields because there are more than enough buyers.

      Particularly over the past six months, states and municipalities have
rushed to take advantage of lower borrowing costs by financing new projects and
refinancing existing debt at lower rates. As a result, the supply of municipal
bonds for the first half of 1998 was about 60% higher than it was in the first
half of 1997.

      In contrast, the supply of U.S. Treasury securities fell because of the
federal government's progress toward achieving a balanced budget. The strong
economy has bolstered tax revenues, requiring the government to borrow less.
Yet, demand for U.S. Treasury securities has remained high, especially from
overseas investors seeking a safe haven from volatile foreign markets.

account.

 An interview with your Fund's manager
- --------------------------------------------------------------------------------

"These economic influences have allowed longer-term interest rates...

Where did you find attractive investment opportunities under these market
conditions?

The Fund emphasized quality-rated bonds with the current tight yield spreads but
did seek out undervalued situations in higher-yielding, lower-rated credits.
Lower quality bonds usually offer higher yields than top quality bonds, and they
tend to appreciate more as the issuers' credit profiles improve. For example,
we've found opportunities in Pennsylvania's healthcare industry where
consolidation and heightened competition have benefited many hospitals. Early in
the 12-month period, we invested in bonds issued by hospitals that, in our view,
were most likely to meet successfully the challenges of the managed-care
marketplace. Through-out the period, we saw these bonds' value rise as the
healthcare industry restructured and their issuers' competitive positions
improved. We later sold some of these holdings at a profit, reinvesting the
proceeds in other areas.

      We also found attractive opportunities for income and diversification from
bonds issued by U.S. territories such as Puerto Rico and Guam. Under federal
law, income from these bonds is exempt from federal and state income taxes for
residents of all states. Most sig-nificantly, during the past six months we
established a position in insured tax-exempt bonds issued by housing projects in
Guam. These projects were built in response to a housing shortage for U.S.
military personnel, tourists and retirees. As a result, these residences are
100% occupied, giving them the revenues required to repay their bonds.

"...to move lower relative to short-term interest rates."

What types of projects do the Fund's holdings help to finance?

We've invested in bonds that support a wide variety of purposes, ranging from
airports to water works. Over the past year, however, we have found particularly
attractive values in certain industries. For example, the growing need for
senior citizen housing has spurred development of adult living facilities in
Pennsylvania and elsewhere across the country. The aging of America indicates
that demand for senior housing should remain high, enhancing these projects'
ability to meet their debt obligations.

Have you avoided any areas of the municipal bond market?

We have tended to favor revenue bonds over general obligation bonds. Revenue
bonds are repaid from income generated by the underlying facility, such as sewer
systems or highways supported by fees and tolls. General obligation bonds, on
the other hand, are repaid from general tax revenues, making them more
vulnerable to credit-rating downgrades if economic conditions deteriorate.

      We have also been careful with regard to electric utilities because
deregulation is changing the entire power-generation industry. We are waiting
for the competitive picture to become clearer before we invest more
substantially in this area.

 An interview with your Fund's manager
- --------------------------------------------------------------------------------

What is your outlook for Pennsylvania's municipal bond market?

We are optimistic because we expect the Pennsylvania municipal bond market to
perform in a manner consistent with the national market. First, tax-exempt bonds
are inexpensive relative to comparable taxable securities because of higher
supply. On average, municipal bonds have historically provided about 85% of the
pre-tax yield of U.S. Treasury securities. As of July 31, municipal bonds
provided almost 95% of taxable bonds' yield. We expect municipal bond prices to
rise as yields fall when the relationship between taxable and tax-exempt bonds
returns to more normal levels. Second, we expect demand for municipal bonds to
increase when common stocks lose their luster. Many individuals, including
Pennsylvania residents, have happily remained invested in equities because
stocks have generated stellar returns over the past three years. If the stock
market corrects, we believe many of these investors will turn to the relative
safety and stability of tax-exempt bonds.

      In addition, we are optimistic about the future of the U.S. economy. We
expect the slowdown in Asia to constrain U.S. economic growth, preventing the
Federal Reserve from raising short-term interest rates in an effort to forestall
an acceleration of inflation.

Pennsylvania personal income taxes, while attempting to preserve capital.

 Fund performance
- --------------------------------------------------------------------------------

How Has the Fund Performed? Below is a discussion by the Manager of the Fund's
performance during its fiscal year ended July 31, 1998, followed by a graphical
comparison of the Fund's performance to an appropriate broad-based market index.

      o Management's Discussion of Performance. During the Fund's fiscal year
that ended July 31, 1998, Oppenheimer Pennsylvania Municipal Fund's performance
was affected by positive domestic economic conditions and low inflation in a
declining interest-rate environment.

      These economic influences have allowed longer-term interest rates to move
lower relative to short-term interest rates. Because bond prices rise when
interest rates decline, most sectors of the U.S. bond market provided
above-average total returns over the past year. However, this has also caused
yields on most fixed-income securities, including many of the Fund's
investments, to decline during the period. As a result, the Fund reduced its
dividend in December of 1997. The Manager's emphasis on quality bonds, its
investments in higher yielding, lower-rated bonds, and investments in Puerto
Rico and Guam were all contributing factors to the Fund's performance. The
Fund's portfolio holdings, allocations and strategies are subject to change.

      During the Fund's fiscal year ended July 31, 1998, the Fund maintained the
practice, to the extent consistent with the amount of the Fund's net investment
income and other distributable income, of attempting to pay dividends on Class A
shares at a constant level. This practice required the Manager, consistent with
the Fund's investment objectives and investment restrictions, to monitor the
Fund's portfolio and select higher yielding securities when deemed appropriate
to maintain necessary net investment income levels.


                   10 Oppenheimer Pennsylvania Municipal Fund
<PAGE>

      o Comparing the Fund's Performance to the Market. The graphs that follow
show the performance of a hypothetical $10,000 investment in each class of
shares of the Fund held until July 31, 1998. In the case of Class A shares,
performance is measured from the Fund's inception on September 18, 1989, in the
case of Class B shares, from the inception of the Class on May 3, 1993, and in
the case of Class C shares, from the inception of the Class on August 29, 1995.

      The Fund's performance is compared to that of the Lehman Brothers
Municipal Bond Index, an unmanaged index of a broad range of investment grade
municipal bonds that is widely regarded as a measure of the performance of the
general municipal bond market. Index performance reflects the reinvestment of
income but does not consider the effect of capital gains or transaction costs,
and none of the following data shows the effect of taxes. Also, the Fund's
performance data reflects the effect of Fund business and operating expenses.
While index comparisons may be useful to provide a benchmark for the Fund's
performance, it must be noted that the Fund's investments are not limited to the
securities in any one index. Moreover, the index performance data does not
reflect an assessment of the risk of the investments included in the index.

1. Represents the current interest rate for a variable rate bond known as an
"inverse floater" which pays interest at a rate that varies inversely with
short-term interest rates. As interest rates rise, inverse floaters produce less
current income. Their price may be more volatile than the price of a comparable
fixed-rate security. Inverse floaters amount to $8,127,028 or 8.46% of the
Fund's net assets as of July 31, 1998.

2. For zero coupon bonds, the interest rate shown is the effective yield on the
date of purchase.

3. Identifies issues considered to be illiquid or restricted--See Note 6 of
Notes to Financial Statements.

================================================================================
1. Significant Accounting Policies

Oppenheimer Pennsylvania Municipal Fund (the Fund) is a separate series of
Oppenheimer Multi-State Municipal Trust, a non-diversified, open-end management
investment company registered under the Investment Company Act of 1940, as
amended. The Fund's investment objective is to seek as high a level of current
interest income exempt from Federal and Pennsylvania personal income taxes for
individual investors as is available from Municipal Securities and consistent
with preservation of capital. The Fund's investment advisor is OppenheimerFunds,
Inc. (the Manager). The Fund offers Class A, Class B and Class C shares. Class A
shares are sold with a front-end sales charge. Class B and Class C shares may be
subject to a contingent deferred sales charge. All classes of shares have
identical rights to earnings, assets and voting privileges, except that each
class has its own distribution and/or service plan, expenses directly
attributable to that class and exclusive voting rights with respect to matters
affecting that class. Class B shares will automatically convert to Class A
shares six years after the date of purchase. The following is a summary of
significant accounting policies consistently followed by the Fund.

- --------------------------------------------------------------------------------
Investment Valuation. Portfolio securities are valued at the close of the New
York Stock Exchange on each trading day. Listed and unlisted securities for
which such information is regularly reported are valued at the last sale price
of the day or, in the absence of sales, at values based on the closing bid or
the last sale price on the prior trading day. Long-term and short-term
"non-money market" debt securities are valued by a portfolio pricing service
approved by the Board of Trustees. Such securities which cannot be valued by an
approved portfolio pricing service are valued using dealer-supplied valuations
provided the Manager is satisfied that the firm rendering the quotes is reliable
and that the quotes reflect current market value, or are valued under
consistently applied procedures established by the Board of Trustees to
determine fair value in good faith. Short-term "money market type" debt
securities having a remaining maturity of 60 days or less are valued at cost (or
last determined market value) adjusted for amortization to maturity of any
premium or discount.

 Notes to Financial Statements  (Continued)

================================================================================
1. Significant Accounting Policies  (continued)

Allocation of Income, Expenses, Gains and Losses. Income, expenses (other than
those attributable to a specific class), gains and losses are allocated daily to
each class of shares based upon the relative proportion of net assets
represented by such class. Operating expenses directly attributable to a
specific class are charged against the operations of that class.

- --------------------------------------------------------------------------------
Federal Taxes. The Fund intends to continue to comply with provisions of the
Internal Revenue Code applicable to regulated investment companies and to
distribute all of its taxable income, including any net realized gain on
investments not offset by loss carryovers, to shareholders. Therefore, no
federal income or excise tax provision is required. At July 31, 1998, the Fund
had available for federal income tax purposes an unused capital loss carryover
of approximately $1,446,000, which expires between 2002 and 2006.

- --------------------------------------------------------------------------------
Trustees' Fees and Expenses. The Fund has adopted a nonfunded retirement plan
for the Fund's independent trustees. Benefits are based on years of service and
fees paid to each trustee during the years of service. During the year ended
July 31, 1998, a provision of $38,681 was made for the Fund's projected benefit
obligations, and payments of $3,017 were made to retired trustees, resulting in
an accumulated liability of $65,313 at July 31, 1998.

            The Board of Trustees had adopted a deferred compensation plan for
independent Trustees that enables Trustees to elect to defer receipt of all or a
portion of annual fees they are entitled to receive from the Fund. Under the
plan, the compensation deferred is periodically adjusted as though an equivalent
amount had been invested for the Trustee in shares of one or more Oppenheimer
funds selected by the Trustee. The amount paid to the Trustee under the plan
will be determined based upon the performance of the selected funds. Deferral of
Trustees' fees under the plan will not affect the net assets of the Fund, and
will not materially affect the Fund's assets, liabilities or net income per
share.

- --------------------------------------------------------------------------------
Distributions to Shareholders. The Fund intends to declare dividends separately
for Class A, Class B and Class C shares from net investment income each day the
New York Stock Exchange is open for business and pay such dividends monthly.
Distributions from net realized gains on investments, if any, will be declared
at least once each year.


                   26 Oppenheimer Pennsylvania Municipal Fund
<PAGE>

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

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

================================================================================
Classification of Distributions to Shareholders. Net investment income (loss)
and net realized gain (loss) may differ for financial statement and tax
purposes. The character of the distributions made during the year from net
investment income or net realized gains may differ from its ultimate
characterization for federal income tax purposes. Also, due to timing of
dividend distributions, the fiscal year in which amounts are distributed may
differ from the fiscal year in which the income or realized gain was recorded by
the Fund.

            The Fund adjusts the classification of distributions to shareholders
to reflect the differences between financial statement amounts and distributions
determined in accordance with income tax regulations. Accordingly, during the
year ended July 31, 1998, amounts have been reclassified to reflect a decrease
in overdistributed net investment income of $83,433, a decrease in accumulated
net realized losses of $112,510, and a decrease in paid-in capital of $195,943.

- --------------------------------------------------------------------------------
Other. Investment transactions are accounted for on the date the investments are
purchased or sold (trade date). Original issue discount on securities purchased
is amortized over the life of the respective securities, in accordance with
federal income tax requirements. As of November 4, 1997, in order to conform
book and tax bases, the Fund began amortization of premiums on securities for
book purposes. Such cumulative change was limited to a reclassification
adjustment and had no impact on net assets or total increase (decrease) in net
assets. Accordingly, during the year ended July 31, 1998, amounts have been
reclassified to reflect an increase in net unrealized appreciation of
investments of $882,749. Paid-in capital was decreased for the same amount. For
bonds acquired after April 30, 1993, on disposition or maturity, taxable
ordinary income is recognized to the extent of the lesser of gain or market
discount that would have accrued over the holding period. Realized gains and
losses on investments and unrealized appreciation and depreciation are
determined on an identified cost basis, which is the same basis used for federal
income tax purposes.

            The Fund concentrates its investments in Pennsylvania and,
therefore, may have more credit risks related to the economic conditions of
Pennsylvania than a portfolio with a broader geographical diversification.

            The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of income and expenses during the reporting
period. Actual results could differ from those estimates.

4. Management Fees and Other Transactions with Affiliates

Management fees paid to the Manager were in accordance with the investment
advisory agreement with the Fund which provides for a fee of 0.60% of the first
$200 million of average annual net assets, 0.55% of the next $100 million, 0.50%
of the next $200 million, 0.45% of the next $250 million, 0.40% of the next $250
million and 0.35% of average annual net assets in excess of $1 billion.
Effective January 1, 1997, the Manager has voluntarily undertaken to waive a
portion of its management fee, whereby the Fund pays a fee not to exceed 0.57%
of average annual net assets.

            For the year ended July 31, 1998, commissions (sales charges paid by
investors) on sales of Class A shares totaled $250,587, of which $48,212 was
retained by OppenheimerFunds Distributor, Inc. (OFDI), a subsidiary of the
Manager, as general distributor, and by an affiliated broker/dealer. Sales
charges advanced to broker/dealers by OFDI on sales of the Fund's Class B and
Class C shares totaled $205,688 and $24,690, respectively, of which $4,164 was
paid to an affiliated broker/dealer for Class B. During the year ended July 31,
1998, OFDI received contingent deferred sales charges of $48,900 upon redemption
of Class B shares as reimbursement for sales commissions advanced by OFDI at the
time of sale of such shares.

            OppenheimerFunds Services (OFS), a division of the Manager, is the
transfer and shareholder servicing agent for the Fund and for other registered
investment companies. OFS's total costs of providing such services are allocated
ratably to these companies.

            Expenses paid indirectly represent a reduction of custodian fees for
earnings on cash balances maintained by the Fund.

            The Fund has adopted a Service Plan for Class A shares to reimburse
OFDI for a portion of its costs incurred in connection with the personal service
and maintenance of shareholder accounts that hold Class A shares. Reimbursement
is made quarterly at an annual rate that may not exceed 0.15% of the average
annual net assets of Class A shares of the Fund. OFDI uses the service fee to
reimburse brokers, dealers, banks and other financial institutions quarterly for
providing personal service and maintenance of accounts of their customers that
hold Class A shares. During the year ended July 31, 1998, OFDI paid $6,691 to an
affiliated broker/dealer as reimbursement for Class A personal service and
maintenance expenses.

================================================================================
4. Management Fees and Other Transactions with Affiliates  (continued)

The Fund has adopted Distribution and Service Plans for Class B and Class C
shares to compensate OFDI for its costs in distributing Class B and Class C
shares and servicing accounts. Under the Plans, the Fund pays OFDI an annual
asset-based sales charge of 0.75% per year on Class B and Class C shares, for
its services rendered in distributing Class B and Class C shares. OFDI also
receives a service fee of 0.25% (voluntarily reduced to 0.15% by the Fund's
Board) per year to compensate dealers for providing personal services for
accounts that hold Class B and Class C shares. Each fee is computed on the
average annual net assets of Class B and Class C shares, determined as of the
close of each regular business day. During the year ended July 31, 1998, OFDI
paid $1,930 to an affiliated broker/dealer as compensation for Class B personal
service and maintenance expenses and retained $164,757 and $27,981,
respectively, as compensation for Class B and Class C sales commissions and
service fee advances, as well as financing costs. If either Plan is terminated
by the Fund, the Board of Trustees may allow the Fund to continue payments of
the asset-based sales charge to OFDI for distributing shares before the Plan was
terminated. At July 31, 1998, OFDI had incurred excess distribution and
servicing costs of $597,509 for Class B and $51,599 for Class C.

================================================================================
5. Futures Contracts

The Fund may buy and sell interest rate futures contracts in order to gain
exposure to or protect against changes in interest rates. The Fund may also buy
or write put or call options on these futures contracts.

            The Fund generally sells futures contracts to hedge against
increases in interest rates and the resulting negative effect on the value of
fixed rate portfolio securities. The Fund may also purchase futures contracts to
gain exposure to changes in interest rates as it may be more efficient than
actually buying fixed income securities.

            Upon entering into a futures contract, the Fund is required to
deposit either cash or securities (initial margin) in an amount equal to a
certain percentage of the contract value. Subsequent payments (variation margin)
are made or received by the Fund each day. The variation margin payments are
equal to the daily changes in the contract value and are recorded as unrealized
gains and losses. The Fund recognizes a realized gain or loss when the contract
is closed or expires.

            Risks of entering into futures contracts (and related options)
include the possibility that there may be an illiquid market and that a change
in the value of the contract or option may not correlate with changes in the
value of the underlying securities.

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

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

================================================================================
6. Illiquid and Restricted Securities

At July 31, 1998, investments in securities included issues that are illiquid or
restricted. Restricted securities are often purchased in private placement
transactions, are not registered under the Securities Act of 1933, may have
contractual restrictions on resale, and are valued under methods approved by the
Board of Trustees as reflecting fair value. A security may be considered
illiquid if it lacks a readily available market or if its valuation has not
changed for a certain period of time. The Fund intends to invest no more than
10% of its net assets (determined at the time of purchase and reviewed
periodically) in illiquid and restricted securities. Certain restricted
securities, eligible for resale to qualified institutional investors, are not
subject to that limit. The aggregate value of illiquid or restricted securities
subject to this limitation at July 31, 1998, was $4,265,000, which represents
4.44% of the Fund's net assets.

================================================================================
7. Bank Borrowings

The Fund may borrow from a bank for temporary or emergency purposes including,
without limitation, funding of shareholder redemptions provided asset coverage
for borrowings exceeds 300%. The Fund has entered into an agreement which
enables it to participate with other Oppenheimer funds in an unsecured line of
credit with a bank, which permits borrowings up to $400 million, collectively.
Interest is charged to each fund, based on its borrowings, at a rate equal to
the Federal Funds Rate plus 0.35%. Borrowings are payable 30 days after such
loan is executed. The Fund also pays a commitment fee equal to its pro rata
share of the average unutilized amount of the credit facility at a rate of
0.0575% per annum.

            The Fund had no borrowings outstanding during the year ended July
31, 1998.

 Independent Auditors' Report
- --------------------------------------------------------------------------------

================================================================================
The Board of Trustees and Shareholders of
Oppenheimer Pennsylvania Municipal Fund:

We have audited the accompanying statements of investments and assets and
liabilities of Oppenheimer Pennsylvania Municipal Fund (a series of Oppenheimer
Multi-State Municipal Trust) as of July 31, 1998, the related statement of
operations for the year then ended, the statements of changes in net assets for
each of the years in the two-year period then ended, and the financial
highlights for each of the years in the two-year period then ended, the
seven-month period ended July 31, 1996 and for each of the years in the
three-year period ended December 31, 1995. These financial statements and
financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits.

            We conducted our audits in accordance with generally accepted
auditing standards. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements and
financial highlights are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. Our procedures included confirmation of securities
owned as of July 31, 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 Oppenheimer Pennsylvania Municipal Fund as of July 31, 1998, the
results of its operations for the year then ended, the changes in its net assets
for each of the years in the two-year period then ended, and the financial
highlights for each of the years in the two-year period then ended, the
seven-month period ended July 31, 1996, and for each of the years in the
three-year period ended December 31, 1995, in conformity with generally accepted
accounting principles.

 Federal Income Tax Information  (Unaudited)
- --------------------------------------------------------------------------------

================================================================================
In early 1999, shareholders will receive information regarding all dividends and
distributions paid to them by the Fund during calendar year 1998. Regulations of
the U.S. Treasury Department require the Fund to report this information to the
Internal Revenue Service.

            None of the dividends paid by the Fund during the fiscal year ended
July 31, 1998, are eligible for the corporate dividend-received deduction. The
dividends were derived from interest on municipal bonds and are not subject to
federal income tax. To the extent a shareholder is subject to any state or local
tax laws, some or all of the dividends received may be taxable.

            The foregoing information is presented to assist shareholders in
reporting distributions received from the Fund to the Internal Revenue Service.
Because of the complexity of the federal regulations which may affect your
individual tax return and the many variations in state and local tax
regulations, we recommend that you consult your tax advisor for specific
guidance.
