As of January 31, 2000, Oppenheimer Pennsylvania Municipal Fund's Class A shares
provided a dividend yield, at Net Asset Value, of 5.92%!(1)

Oppenheimer Pennsylvania Municipal Fund announced three dividend increases for
Class A shares since this report last year--$.002 per share starting with the
June distribution, $.003 per share starting with the September distribution, and
an additional $.002 per share starting with the February, 2000 distribution.
That's three dividend increases--raising the dividend by over 14%--just since
January, 1999!

30-day SEC yield was 6.16%. Dividend yield at NAV (based on last distribution)
is annualized and divided by period-end Net Asset Value. Standardized yield is
based on net investment income for the 30-day period ended 1/31/00. Falling net
asset values will tend to artificially raise yields.

4. This assumes shares were purchased and held for the entire accrual period.
Since dividends accrue daily, your actual distributions will vary depending on
the date you purchased your shares and any account activity during the month.
Income distributions include all accrued income earned by the Fund during the
reporting period. The Fund attempts to pay dividends on Class A shares at a
constant level. There is no assurance that it will be able to do so. The Board
of Trustees may change the targeted dividend rate at any time without prior
notice to shareholders. Additionally, the amount of those dividends and the
dividends paid on Class B and Class C shares may vary over time, depending on
market conditions, the composition of the Fund's portfolio, and expenses borne
by the particular class of shares. Dividends and distributions paid on Class A
shares will generally be higher than dividends for Class B and Class C shares,
which normally have higher expenses than Class A. The Fund cannot guarantee that
it will pay any dividends or distributions. The Fund's policy of seeking to
maintain a steady dividend for its Class A shares did not materially affect
portfolio strategies during this reporting period.

PRESIDENT'S LETTER

[photo with caption]

[Bridget A. Macaskill
President,
Oppenheimer
Pennsylvania
Municipal Fund}


Dear shareholder,

Whenever a new year begins--let alone a new decade or century--it makes sense to
pause a moment to assess where we've been and where we're going.

In retrospect, U.S. stocks and bonds in 1999 were subject to sudden and
substantial swings in investor sentiment because of economic uncertainty. When
the year began, investors were concerned that growth in the United States might
slow in response to economic weakness overseas. At mid-year, investors were
concerned that the economy was too strong, potentially rekindling inflationary
pressures. Yet, by year end, it became clearer that while the U.S. economy grew
robustly in 1999, inflation remained at low levels. Indeed, investors appeared
more comfortable with the economy after the Federal Reserve Board demonstrated
its inflation-fighting resolve by raising interest rates three times between
June and November.

As is normal in a rising-interest-rate environment, bond prices generally
declined in 1999, led lower by U.S. Treasury bonds. In the stock market, while
most major indices advanced, strong performance was mostly limited to a handful
of large-capitalization growth companies, principally in the technology arena.
Smaller and value-oriented stocks provided particularly lackluster returns, and
overall, foreign stocks outperformed U.S. stocks in 1999.

Looking forward, we expect the U.S. economy to remain on a moderate-growth,
low-inflation course. As recent revisions of 1999's economic statistics
demonstrated, the economy has defied many analysts' forecasts by growing at a
strong rate, which should be positive for the bond market. Similarly, positive
economic forces could help the stock market's performance broaden to include
value-oriented and smaller stocks.

We see particularly compelling opportunities outside of the U.S. market. Many
foreign stocks also ended 1999 more attractively valued than large-cap U.S.
stocks, and economic trends in overseas markets could lead to higher stock
prices. In Europe, corporate restructuring has just begun, giving companies
there the same potential for cost-cutting and

- --------------------------------------------------------------------------------
PRESIDENT'S LETTER
- --------------------------------------------------------------------------------

productivity improvements that U.S. companies enjoyed 10 years ago. In Japan and
Asia, economic recovery is expected to gain strength, which could allow stocks
to rally from relatively low levels.

Another 1999 trend that should remain in force in 2000 is the growth of
businesses related to the Internet. The rise of e-commerce has been good for
consumers and the economy because of greater price competition, which has helped
keep inflation under control. The Internet has also been good for investors, as
even companies with no earnings have seen their stock prices soar. Clearly,
while the Internet is here to stay, not all "dot-com" companies will survive,
and many of these high-flying Internet stocks will eventually--and perhaps very
suddenly--return to more reasonable levels. The long-term winners are most
likely to be companies that support the Internet's growth with content or
infrastructure.

What else is in store for investors in 2000? While we do not have an infallible
crystal ball, we believe that in almost any investment environment, consistent
success stems from an unwavering focus on fundamental investment principles such
as maintaining a long-term perspective, using diversification to manage risks,
and availing oneself of the services of a knowledgeable financial advisor.
Indeed, these principles serve as the foundation for every investment we offer,
helping to make OppenheimerFunds The Right Way to Invest in 2000 and beyond.


Sincerely,

How has Oppenheimer Pennsylvania Municipal Fund performed during
the six-month period ended January 31, 2000?

The big news in the past six-month period was the Fund's two dividend
increases--$.003 per share, announced last August, and an additional $.002
announced on January 31, 2000. Together with a $.002 increase announced last
May, the Fund's dividend has gone from 4.9 cents per share to 5.6 cents per
share--a dividend increase of over 14% since this report last year!

The Fund's Class A shares provided an annualized tax-free dividend yield of
5.92% (computed without sales charges) as of January 31, 2000. This tax-free
dividend yield is the equivalent of 8.82% in taxable yield for a Pennsylvania
taxpayer in the 32.9% combined Pennsylvania State and federal income tax
bracket. For taxpayers subject to higher federal tax rates, or additional local
income taxes, the equivalent yield would make your Fund investment even more
attractive.

What is the current state of the Pennsylvania municipal bond market?

Conditions in the Pennsylvania municipal bond market have mirrored those of the
national municipal bond market during this reporting period. The nation's
healthy economy has impacted positively on municipal finances, helping the
overall credit quality of municipal bond issuers to remain solid. However, this
vigorous national economic activity has also led the Federal Reserve to increase
short-term interest rates, leading to higher interest rates across the yield
curve. As a result, municipal bond prices have been on the decline
nationally--as well as in Pennsylvania. Since heightened interest rates increase
the cost of borrowing money, municipalities have scaled back on the number of
new bonds that they issue. During 1999, for example, 28% fewer new municipal
bonds were issued in Pennsylvania than during 1998.

Rising interest rates have also produced widened credit yield spreads throughout
the municipal market. This means that the yield on bonds issued by smaller, BBB
and unrated municipalities has risen at a greater rate than the yield on insured
bonds, and bonds issued by larger municipalities. Stated differently, the price
of municipal bonds of smaller, BBB and unrated municipalities has decreased more
than the others. This is a normal part of the interest rate cycle, and does not
reflect a decline in the general credit quality of lower-rated issuers--in fact,
the Fund did not experience any credit losses during this period of volatility.
Changes in credit spreads are cyclical by nature--they typically widen when
interest rates increase and narrow when interest rates decrease. What widening
credit yield spreads can provide investors is the opportunity to earn higher
income on each dollar invested in municipal bonds and bond funds--by buying
when they're "on sale."

Municipal bond prices have declined steadily since October, 1998, but the bulk
of the decline began in June of 1999 when the Fed made the first of four, .25%
increases in the bank overnight borrowing rate. While these interest rate
increases have hurt short-term bond market performance, they potentially produce
two long-term benefits. First, they have helped keep inflation in
check--allowing fixed-income investors to maintain their purchasing power.
Second, the difference between long-term municipal bond yields and inflation has
widened--resulting in higher "real interest rates" for municipal bond and bond
fund investors. Under current circumstances, a well-diversified municipal bond
fund can offer income-oriented investors superior yield and total return
potential.

How do you plan to manage the portfolio to take advantage of these conditions?

Current market conditions play right into our research-driven portfolio
management style. We have historically used our rigorous in-house research
capability to uncover the true value of precisely those bonds whose yields have
recently increased the most. Our sharp focus on smaller municipal issuers helps
us





                                 6 OPPENHEIMER PENNSYLVANIA MUNICIPAL FUND
<PAGE>

to find bonds which represent good credit quality that are often overlooked
by our competitors. Current prices now enable us to capture the increased yield
advantages offered by smaller and lower-rated issues while broadening
diversification in the Fund. As a result, we have increased the breadth of our
holdings of smaller, BBB-rated issues and improved the Fund's tax-free yield.

For example, we recently purchased bonds issued by the Northumberland County
Authority to finance construction of a career and arts center. These bonds do
not carry an institutional credit rating because the small size of the issue
made the cost of obtaining a bond rating prohibitive. However, payment on the
bonds is unconditionally guaranteed by the County. Through our research, we were
able to learn that Northumberland County has a comparatively low debt burden and
historically successful financial management. Analyzing these factors, and
similar facts that rating agencies evaluate, we concluded that these bonds
possessed credit characteristics similar to those that receive an investment
grade rating. The Northumberland County Authority bonds had an effective
maturity of 13 years, and yielded 6.75%. This represented a yield premium of
1.00 percent over insured general obligation bonds with similar effective
maturities. A year earlier, such a bond would have paid investors only half of
that yield premium. Over the longer term, our strategy of pursuing small issuers
like this should benefit shareholders by securing an above average rate of
tax-free income while creating the opportunity for greater total returns should
these bonds return to their historic average pricing levels.

Have you been finding value in other areas?

With the backdrop of rising interest rates, we began to reduce our holdings of
lower coupon bonds that are more sensitive to interest rates, replacing them
with less volatile issues. During the last six-month period we have been able to
purchase some high quality bonds which we feel carry very low interest rate
risk--strengthening the foundation of the portfolio. We have been successfully
combing the secondary markets for premium coupon callable bonds, seeking those
with characteristics that

indicate the bond issuer may continue to pay interest, rather than redeem the
bond at the first possible redemption date. We have found such bonds in the
housing sector. Adding them to the portfolio at current prices has provided
above-market yields with very low price volatility.

Is now a good time for me to add to my investment in Oppenheimer
Pennsylvania Municipal Fund?

If you like to buy things when they're on sale, now is a good time to add to
your investment in Oppenheimer Pennsylvania Municipal Fund. Recent declines
in municipal bond prices have been due primarily to rising interest rates. The
effect of interest rate increases on "real interest rates," as discussed
earlier, has made the Oppenheimer Pennsylvania Municipal Bond Fund an attractive
value for investors.

In our experience, we can remember few other times when the market has so
clearly favored municipals--especially considering that municipal income is
generally free of federal, Pennsylvania state and, if applicable, local personal
income taxes. Our management style is positioned to generate yield, and yield,
over the long term, comprises the single greatest component of total return on a
fixed-income investment. In other words, yield is total return in the making.

Municipal bond investing, like most other types of investing, should be
undertaken with this type of long-term view. As always, we recommend that you
consult with your financial advisor to review your municipal bond allocation. We
feel that market conditions have generated some outstanding values which can
contribute to this portfolio, and we are very positive on the possibilities for
the municipal bond market going forward. We hope that you are, as well.

1. Dividend Yield at Maximum Offering Price (based on last distribution) and
Standardized Yield (based on net investment income for the 30-day period ended
1/31/00) are annualized and divided by period-end offering price. Dividend yield
at NAV does not include sales charges. Falling share prices may artificially
increase yields.

2. This performance is not annualized. Total returns include changes in
share price and reinvestment of dividends and capital gains distributions in a
hypothetical investment for the periods shown. Class A return at maximum
offering price includes the current maximum initial sales charge of 4.75%. Class
B return at maximum offering price includes the applicable contingent deferred
sales charge of 5% (1-year) and 1% (5 years). Because Class B shares convert to
Class A shares 72 months after purchase, the "life-of-class" return for Class B
uses Class A performance for the period after conversion. Class C return at
maximum offering price includes the contingent deferred sales charge of 1%
(1-year). An explanation of the different performance calculations is in the
Fund's prospectus. Class B and C shares are subject to an annual 0.75%
asset-based sales charge. Performance without sales charges includes changes in
net asset value per share without deducting any sales charges. Such performance
would have been lower if sales charges had been taken into account. Inception
dates: Class A - 9/18/89; Class B - 5/3/93; Class C - 8/29/95.

invested assets and are subject to change. The Fund may invest up to 25% of its
assets in below-investment-grade securities which carry greater risk that an
issuer may default on repayment of principal or interest. Securities rated by
any rating organization are included in the equivalent Standard and Poor's
rating category. Average credit quality and allocation include securities rated
by a national rating organization as well as unrated securities (22% of total

periods shown. Class A returns at MOP include the current maximum initial sales
charge of 4.75%. Class B returns at MOP include the applicable contingent
deferred sales charge of 5%(1-year) and 1% (5-year). Because Class B shares
convert to Class A shares 72 months after purchase, the "life-of-class" return
for Class B uses Class A performance for the period after conversion. Class C

 1. Identifies issues considered to be illiquid or restricted--see Note 5 of
 Notes to Financial Statements.
 2. 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 $11,148,388 or
 12.10% of the Fund's net assets as of January 31, 2000.
 3. For zero coupon bonds, the interest rate shown is the effective yield on the
 date of purchase.

 As of January 31, 2000, securities subject to the alternative minimum tax
 amount to $32,544,268 or 35.32% of the Fund's net assets.

 Distribution of investments by industry of issue, as a percentage of total
 investments at value, is as follows:

 NOTES TO FINANCIAL STATEMENTS Unaudited

 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 as
 is available from municipal securities, 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 at their offering price, which is normally net asset value plus an initial
 sales charge. Class B and Class C shares are sold without an initial sales
 charge but may be subject to a contingent deferred sales charge (CDSC). All
 classes of shares have identical rights to earnings, assets and voting
 privileges, except that each class has its own expenses directly attributable
 to that class and exclusive voting rights with respect to matters affecting
 that class. Classes A, B and C shares have separate distribution and/or service
 plans. 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.
- --------------------------------------------------------------------------------
 Securities Valuation. Securities for which quotations are readily available
 are valued at the last sale price, or if in the absence of a sale, at the last
 sale price on the prior trading day if it is within the spread of the closing
 bid and asked prices, and if not, at the closing bid price. Securities (includ-
 ing restricted securities) for which quotations are not readily available are
 valued primarily using dealer-supplied valuations, a portfolio pricing service
 authorized by the Board of Trustees, or at their fair value. Fair value is
 determined in good faith under consistently applied procedures under the
 supervision of the Board of Trustees. Short-term "money market type" debt
 securities with remaining maturities of sixty days or less are valued at cost
 (or last determined market value) and adjusted for amortization or accretion to
 maturity of any premium or discount.
- --------------------------------------------------------------------------------
 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. As of July 31, 1999, the
 Fund had available for federal tax purposes an unused capital loss carryover
 of approximately $1,552,000, which expires between 2002 and 2007.


                                 26 OPPENHEIMER PENNSYLVANIA MUNICIPAL FUND
<PAGE>
- --------------------------------------------------------------------------------
 Trustees' Compensation. The Fund has adopted an unfunded retirement plan for
 the Fund's independent Board of Trustees. Benefits are based on years of
 service and fees paid to each trustee during the years of service. During the
 six months ended January 31, 2000, a provision of $1,861 was made for the
 Fund's projected benefit obligations, resulting in an accumulated liability of
 $62,795 as of January 31, 2000.
       The Board of Trustees has adopted a deferred compensation plan for
 independent trustees that enables trustees to elect to defer receipt of all or
 a portion of annual compensation 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 Board of Trustees in shares of one
 or more Oppenheimer funds selected by the trustee. The amount paid to the Board
 of Trustees 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 investment income per share.
- --------------------------------------------------------------------------------
 Dividends and Distributions to Shareholders. Dividends and distributions to
 shareholders, which are determined in accordance with income tax regulations,
 are recorded on the ex-dividend date.
- --------------------------------------------------------------------------------
 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 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.
- --------------------------------------------------------------------------------
 Expense Offset Arrangements. Expenses paid indirectly represent a reduction of
 custodian fees for earnings on cash balances maintained by the Fund.
- --------------------------------------------------------------------------------
 Other. Investment transactions are accounted for as of trade date. Original
 issue discount is accreted and premium is amortized in accordance with federal
 income tax requirements. For municipal 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 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. Fees and Other Transactions with Affiliates

 Management Fees. 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. The Fund's management fee
 for the six months ended January 31, 2000 was 0.60% of the average annual net
 assets of each class of shares, annualized for periods of less than one full
 year, before the voluntary waiver by the Manager.
- --------------------------------------------------------------------------------
 Transfer Agent Fees. OppenheimerFunds Services (OFS), a division of the
 Manager, is the transfer and shareholder servicing agent for the Fund and for
 other Oppenheimer funds. OFS's total costs of providing such services are
 allocated ratably to these funds.
- --------------------------------------------------------------------------------
 Distribution and Service Plan Fees. Under its General Distributor's Agreement
 with the Manager, the Distributor acts as the Fund's principal underwriter in
 the continuous public offering of the different classes of shares of the Fund.

 4. Fees and Other Transactions with Affiliates  Continued

 Class A Service Plan Fees. Under the Class A service plan, the Distributor
 currently uses the fees it receives from the Fund to pay brokers, dealers and
 other financial institutions. The Class A service plan permits reimbursements
 to the Distributor at a rate of up to 0.15% of average annual net assets of
 Class A shares purchased. The Distributor makes payments to plan recipients
 quarterly at an annual rate not to exceed 0.15% of the average annual net
 assets consisting of Class A shares of the Fund. For the six months ended
 January 31, 2000, payments under the Class A Plan totaled $52,333, all of which
 was paid by the Distributor to recipients. That included $2,940 paid to an
 affiliate of the Manager. Any unreimbursed expenses the Distributor incurs with
 respect to Class A shares in any fiscal year cannot be recovered in subsequent
 years.
- --------------------------------------------------------------------------------
 Class B and Class C Distribution and Service Plan Fees. Under each plan,
 service fees and distribution fees are computed on the average of the net asset
 value of shares in the respective class, determined as of the close of each
 regular business day during the period. The Class B and Class C plans provide
 for the Distributor to be compensated at a flat rate, whether the Distributor's
 distribution expenses are more or less than the amounts paid by the Fund under
 the plan during the period for which the fee is paid.
       The Distributor retains the asset-based sales charge on Class B shares.
 The Distributor retains the asset-based sales charge on Class C shares during
 the first year the shares are outstanding. The asset-based sales charges on
 Class B and Class C shares allow investors to buy shares without a front-end
 sales charge while allowing the Distributor to compensate dealers that sell
 those shares.
       The Distributor's actual expenses in selling Class B and Class C shares
 may be more than the payments it receives from the contingent deferred sales
 charges collected on redeemed shares and asset-based sales charges from the
 Fund under the plans. If any plan is terminated by the Fund, the Board of
 Trustees may allow the Fund to continue payments of the asset-based sales
 charge to the Distributor for distributing shares before the plan was
 terminated. The plans allow for the carry-forward of distribution expenses, to
 be recovered from asset-based sales charges in subsequent fiscal periods.

 Distribution fees paid to the Distributor for the six months ended January 31,
 2000:

 5. Illiquid or Restricted Securities

 As of January 31, 2000, 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 also
 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 15% of its net assets (determined at the time of purchase
 and reviewed periodically) in illiquid securities and no more than 10% of its
 net assets in restricted securities. Certain restricted securities, eligible
 for resale to qualified institutional investors, are not subject to that
 limitation. The aggregate value of illiquid or restricted securities subject to
 this limitation as of January 31, 2000, was $7,006,320, which represents 7.60%
 of the Fund's net assets.

================================================================================
 6. Bank Borrowings

 The Fund may borrow up to 10% of its total assets from a bank to purchase
 portfolio securities, or for temporary and emergency purposes. The Fund has
 entered into an agreement which enables it to participate with certain other
 Oppenheimer funds in an unsecured line of credit with a bank, which permits
 borrowings up to $100 million, collectively. Interest is charged to each fund,
 based on its borrowings, at a rate equal to the Federal Funds Rate plus 0.625%.
 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 0.09% per annum. The
 commitment fee allocated to the Fund for the six months ended January 31, 2000,
 was $2,421.
       The Fund had $4,400,000 borrowings outstanding at January 31, 2000. For
 the year ended January 31, 2000, the average monthly loan balance was
 $2,440,000 at an average interest rate of 5.95%.
