The Fund's Objective and Investment Strategies

- -------------------------------------------------------------------------------
What Is The Fund's Investment Objective? 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.
- -------------------------------------------------------------------------------

What Does the Fund Invest In? The Fund invests mainly in Pennsylvania municipal
securities that pay interest exempt from federal and Pennsylvania individual
income taxes, and, for residents of Philadelphia, income exempt from the
investment income tax of the school district of Philadelphia. These primarily
include municipal bonds (which are long-term obligations), municipal notes
(short-term obligations), interests in municipal leases, and tax-exempt
commercial paper. Most of the securities the Fund buys must be "investment
grade" (the four highest rating categories of national rating organizations,
such as Moody's), although the Fund can hold lower-grade securities as well.

The Fund does not limit its investments to securities of a particular
maturity range, and may hold both short- and long-term securities. However, it
currently focuses on longer-term securities to seek higher yields. The Fund may
also use hedging instruments and certain derivative investments to a limited
extent to try to manage investment risks. These investments are more fully
explained in "About the Fund's Investments," below.

|X| How Does the Manager Decide What Securities to Buy or Sell? In
selecting securities for the Fund, the Manager currently looks primarily
throughout Pennsylvania for municipal securities using a variety of factors
which may change over time and may vary in particular cases:
|_| Securities that provide high income
|_| The goal of spreading risk among a wide range of securities of
different issuers within the state, including different agencies
and municipalities
|_| Issues with favorable credit characteristics
|_| Special situations among issuers that provide opportunities
for value

Who Is the Fund Designed For? The Fund is designed for investors who are seeking
income exempt from federal and Pennsylvania income taxes. It does not seek
capital gains or growth. Because it invests in tax-exempt securities, the Fund
is not appropriate for retirement plan accounts or for investors who want to
pursue capital growth.

Main Risks of Investing in the Fund

All investments carry risks to some degree. For bond funds one risk is
that the market prices of the fund's investments will fluctuate when general
interest rates change (this is known as "interest rate risk"). Another risk is
that the issuer of the bond will experience financial difficulties and may
default on its obligation to pay interest and repay principal (this is referred
to as "credit risk"). These general investment risks and the special risks of
certain types of investments that the Fund may hold are described below.

These risks collectively form the risk profile of the Fund and can affect
the value of the Fund's investments, its investment performance, and the prices
of its shares. These risks mean that you can lose money by investing in the
Fund. When you redeem your shares, they may be worth more or less than what you
paid for them.

The Fund's investment Manager, OppenheimerFunds, Inc., tries to reduce
risks by selecting a wide variety of municipal investments, by carefully
researching securities before they are purchased and in some cases by using
hedging techniques. However, changes in the overall market prices of municipal
securities and the income they pay can occur at any time. The share price of the
Fund will change daily based on changes in interest rates and market conditions,
and in response to other economic events. There is no assurance that the Fund
will achieve its investment objective.

How Risky Is the Fund Overall? The value of the Fund's investments in municipal
securities will change over time due to a number of factors. They include
changes in general bond market movements, the change in value of particular
bonds because of an event affecting the issuer, or changes in interest rates
that can affect bond prices overall. The Fund focuses its investments in
Pennsylvania municipal securities and is non-diversified. It will therefore be
vulnerable to the effects of economic changes that affect Pennsylvania
governmental issuers. These changes can affect the value of the Fund's
investments and its price per share. The Fund may invest in derivative
investments. These have additional risks and can cause fluctuations in the
Fund's share prices. In the OppenheimerFunds spectrum, the Fund is more
conservative than some types of taxable bond funds, such as high yield bond
funds, but more aggressive than money market funds.

An investment in the Fund is not a deposit of any bank, and is not insured
or guaranteed by the Federal Deposit Insurance Corporation or any other
government agency.

|X| Credit Risk. Municipal securities are subject to credit risk. Credit
risk relates to the ability of the issuer of a municipal security to make
interest and principal payments on the security as they become due. If the
issuer fails to pay interest, the Fund's income may be reduced and if the issuer
fails to repay principal, the value of that bond and of the Fund's shares may be
reduced. Because the Fund can invest as much as 25% of its assets in municipal
securities below investment grade to seek higher income, the Fund's credit risks
are greater than those of funds that buy only investment grade bonds.

|X| Interest Rate Risks. In addition to credit risks, municipal securities
are subject to changes in value when prevailing interest rates change. When
interest rates fall, the values of outstanding municipal securities generally
rise, and the bonds may sell for more than their face amount. When interest
rates rise, the values of outstanding municipal securities generally decline,
and the bonds may sell at a discount from their face amount. The magnitude of
these price changes is generally greater for bonds with longer maturities. The
Fund currently focuses on longer term securities to seek higher income. When the
average maturity of the Fund's portfolio is longer, its share price may
fluctuate more when interest rates change.

|X| Risks of Non-Diversification -- Investments in Pennsylvania Municipal
Securities. The Fund is "non-diversified." That means that compared to funds
that are diversified, it can invest a greater portion of its assets in the
securities of one issuer, such as bonds issued by the Commonwealth of
Pennsylvania. Having a higher percentage of its assets invested in the
securities of fewer issuers, particularly government issuers of a single state,
could result in greater fluctuations of the Fund's share prices due to economic,
regulatory or political problems in Pennsylvania.

|X| There are Special Risks in Using Derivative Investments. The Fund may
use derivatives to seek increased returns or to try to hedge investment risks.
In general terms, a derivative investment is an investment contract whose value
depends on (or is derived from) the value of an underlying asset, interest rate
or index. Options, futures, "inverse floaters" and variable rate obligations are
examples of derivatives.

If the issuer of the derivative investment does not pay the amount due,
the Fund can lose money on its investment. Also, the underlying security or
investment on which the derivative is based, and the derivative itself, may not
perform the way the Manager expected it to perform. If that happens, the Fund
will get less income than expected or its share price could decline. To try to
preserve capital, the Fund has limits on the amount of particular types of
derivatives it can hold. However, using derivatives can cause the Fund to lose
money on its investments and/or increase the volatility of its share prices.

The Fund's Past Performance

The bar chart and table below show one measure of the risks of investing in the
Fund, by showing changes in the Fund's performance (for its Class A shares) from
year to year for the calendar years since the Fund's inception (9/18/89) and by
showing how the average annual total returns of the Fund's shares compare to
those of a broad-based market index. The Fund's past investment performance is
not necessarily an indication of how the Fund will perform in the future.

[See bar chart in Appendix to the Prospectus]

For the period from 1/1/98 through 9/30/98, the cumulative return (not
annualized) for Class A shares was 4.46%. Sales charges are not included in the
calculations of return in this bar chart, and if those charges were included,
the returns would be less than those shown. During the period shown in the bar
chart, the highest return (not annualized) for a calendar quarter was 7.22%
(1Q'95) and the lowest return for a calendar quarter was -5.35% (1Q'94).

The Fund's average annual total returns in the table include the applicable
sales charge: for Class A, the current maximum initial sales charge of 4.75%;
for Class B, the applicable contingent deferred sales charges of 5% (1-year) and
2% (life of class); for Class C, the 1% contingent deferred sales charge for the
1-year period.

The returns measure the performance of a hypothetical account and assume that
all dividends and capital gains distributions have been reinvested in additional
shares. Because the Fund invests in municipal securities, the Fund's performance
is compared to the Lehman Brothers Municipal Bond Index, an unmanaged index of a
broad range of investment grade municipal bonds that is a measure of the
performance of the general municipal bond market. However, it must be remembered
that the index includes municipal securities from many states while the Fund
focuses on Pennsylvania municipal securities, and the index performance does not
consider the effects of capital gains or transaction costs.

Fees and Expenses of the Fund

The Fund pays a variety of expenses directly for management of its assets,
administration, distribution of its shares and other services. Those expenses
are subtracted from the Fund's assets to calculate the Fund's net asset value
per share. All shareholders therefore pay those expenses indirectly.
Shareholders pay other expenses directly, such as sales charges and account
transaction charges. The following tables are provided to help you understand
the fees and expenses you may pay if you buy and hold shares of the Fund. The
numbers below are based on the Fund's expenses during the fiscal year ended July
31, 1998.

Numbers in the table are based on the Fund's expenses in the last fiscal year,
ended 7/31/98. However, the management fees shown are the amounts that would
have been paid by the Fund if the Manager had not absorbed some expenses under
its voluntary expense undertaking to the Fund. The actual management fees, after
the Manager's waiver, were 0.57% for each class of shares. The Manager can
withdraw that voluntary waiver at any time. Expenses may vary in future years.
"Other expenses" include transfer agent fees, custodial fees, and accounting and
legal expenses the Fund pays.

Examples. These examples are intended to help you compare the cost of
investing in the Fund with the cost of investing in other mutual funds.

The examples assume that you invest $10,000 in a class of shares of the Fund for
the time periods indicated, and reinvest your dividends and distributions. The
first example assumes that you redeem all of your shares at the end of those
periods. The second example assumes you keep your shares. Both examples also
assume that your investment has a 5% return each year and that the class's
operating expenses remain the same. Your actual costs may be higher or lower
because expenses will vary over time. Based on these assumptions your expenses
would be as follows:

- ----------------------------------------------------------------------
If shares are redeemed: 1 year 3 years 5 years
10 years1
- ----------------------------------------------------------------------
- ----------------------------------------------------------------------
Class A Shares $565 $757 $ 965 $1,564

Class B Shares $671 $830 $1,113 $1,604

Class B Shares $171 $530 $913 $1,604
- ----------------------------------------------------------------------
- ----------------------------------------------------------------------
Class C Shares $170 $526 $907 $1,976
- ----------------------------------------------------------------------

In the first example, expenses include the initial sales charge for Class A and
the applicable Class B or Class C contingent deferred sales charges. In the
second example, the Class A expenses include the sales charge, but Class B and
Class C expenses do not include contingent deferred sales charges.

1. Class B expense for years 7 through 10 are based on Class A expenses, since
Class B shares automatically convert to Class A after 6 years.

About the Fund's Investments

The Fund's Principal Investment Policies. The Fund's goal is to seek as high a
level of current interest income that is exempt from federal and Pennsylvania
personal income taxes for individual investors as is available from municipal
securities, consistent with preservation of capital. Under normal market
conditions, the Fund:

|_| attempts to invest 100% of its assets in municipal securities,

|_| as a matter of fundamental policy, invests at least 80%
of its assets in municipal securities, and

|_| invests at least 80% of its total assets in Pennsylvania municipal
securities.

The Statement of Additional Information contains more detailed information
about the Fund's investment policies and risks.

|X| What Municipal Securities Does the Fund Invest In? The Fund buys
municipal bonds and notes, tax-exempt commercial paper, certificates of
participation in municipal leases and other debt obligations.

Pennsylvania municipal securities, on which the Fund focuses its
investments, are municipal securities that are not subject (at the time they are
issued) to Pennsylvania personal income tax, in the opinion of bond counsel to
the issuer. These debt obligations are issued by the Commonwealth of
Pennsylvania and its political subdivisions (such as cities, towns, counties,
agencies and authorities). They also may include debt obligations of the
governments of certain possessions, territories and commonwealths of the United
States if the interest is not subject to Pennsylvania personal income tax.

The Fund may also buy other municipal securities, securities issued by the
governments of the District of Columbia and of other states, as well as their
political subdivisions, authorities and agencies, and securities issued by any
commonwealths, territories or possessions of the United States, or their
respective agencies, instrumentalities or authorities, if the interest paid on
the security is not subject to federal individual income tax (in the opinion of
bond counsel to the issuer at the time the security is issued).

The Fund can buy both long-term and short-term municipal securities.
Long-term securities have a maturity of more than one year. The Fund generally
focuses on longer-term securities, to seek higher income. The values of
longer-term bonds are more affected by changes in interest rates than short-term
bonds. Therefore, the longer the average maturity of the Fund's portfolio, the
more its share prices generally will be affected by changes in interest rates.

Municipal securities are issued to raise money for a variety of public or
private purposes, including financing state or local governments, financing
specific projects or public facilities. The Fund can invest in municipal
securities that are "general obligations," secured by the issuer's pledge of its
full faith, credit and taxing power for the payment of principal and interest.

The Fund can also buy "revenue obligations," payable only from the
revenues derived from a particular facility or class of facilities, or a
specific excise tax or other revenue source. Some of those revenue obligations
are private activity bonds that pay interest that may be a tax preference item
for investors subject to alternative minimum tax.

|X| Ratings of Municipal Securities the Fund Buys. Most of the municipal
securities the Fund buys are "investment grade" at the time of purchase. The
Fund limits its investments in municipal securities that at the time of purchase
are not "investment-grade" to not more than 25% of its total assets. "Investment
grade" securities are those rated within the four highest rating categories of
Moody's, Standard & Poor's, Fitch or Duff & Phelps or another nationally
recognized rating organization, or (if unrated) judged by the Manager to be
investment grade. Rating categories are described in the Statement of Additional
Information. If the securities are not rated, the Manager will use its judgment
to assign a rating category equivalent to that of a rating agency. A reduction
in the rating of a security after its purchase by the Fund will not
automatically require the Fund to dispose of that security. However, the Manager
will evaluate those securities to determine whether to keep them in the Fund's
portfolio.

The Manager may rely to some extent on credit ratings by nationally
recognized rating agencies in evaluating the credit risk of securities selected
for the Fund's portfolio. It may also use its own research and analysis. Many
factors affect an issuer's ability to make timely payments, and the credit risks
of a particular security may change over time.

|_| Special Credit Risks of Lower-Grade Securities. Lower-grade
municipal securities may be subject to greater market fluctuations and greater
risks of loss of income and principal than higher-rated municipal securities.
Securities that are (or that have fallen) below investment grade entail a
greater risk that the issuers of such securities may not meet their debt
obligations. However, by limiting its investments in non-investment grade
municipal securities to not more than 25% of its assets, the Fund may reduce the
effect of some of these risks on its share price and income.

|X| Municipal Lease Obligations. Municipal leases are used by state and
local government authorities to obtain funds to acquire land, equipment or
facilities. The Fund may invest in certificates of participation that represent
a proportionate interest in payments made under municipal lease obligations. If
the government stops making payments or transfers its payment obligations to a
private entity, the obligation could lose value or become taxable.

|X| Can the Fund's Investment Objective and Policies Change? The Fund's
Board of Trustees may change non-fundamental policies without shareholder
approval, although significant changes will be described in amendments to this
Prospectus. Fundamental policies are those that cannot be changed without the
approval of a majority of the Fund's outstanding voting shares. The Fund's
investment objective is a fundamental policy. An investment policy or technique
is not fundamental unless this Prospectus or the Statement of Additional
Information says that the particular policy is fundamental.

Other Investment Strategies. To seek its objective, the Fund may can also use
the investment techniques and strategies described below. These techniques
involve certain risks or are designed to help reduce some of the risks.

|X| Floating Rate/Variable Rate Obligations. Some of the municipal
securities the Fund can purchase have variable or floating interest rates.
Variable rates are adjustable at stated periodic intervals. Floating rates are
automatically adjusted according to a specified market rate for such
investments, such as the percentage of the prime rate of a bank, or the 91-day
U.S. Treasury Bill rate. These obligations may be secured by bank letters of
credit or other credit support arrangements.

Certain types of variable rate bonds known as "inverse floaters" pay
interest at rates that vary as the yields generally available on short-term
tax-exempt bonds change. However, the yields on inverse floaters move in the
opposite direction of yields on short-term bonds in response to market changes.
As interest rates rise, inverse floaters produce less current income, and their
market value can become volatile. Inverse floaters are a type of "derivative
security." Some have a "cap," so that if interest rates rise above the "cap,"
the security pays additional interest income. If rates do not rise above the
"cap," the Fund will have paid an additional amount for a feature that proves
worthless. The Fund anticipates that it will invest not more than 10% of its
total assets in inverse floaters.

|X| Other Derivatives. The Fund may also invest in municipal derivative
securities that pay interest that depends on an external pricing mechanism.
Examples of securities having external pricing mechanisms are interest rate
swaps, municipal bond indices or swap indices.

|X| When-Issued and Delayed Delivery Transactions. The Fund may purchase
municipal securities on a "when-issued" basis and may purchase or sell such
securities on a "delayed delivery" basis. These terms refer to securities that
have been created and for which a market exists, but which are not available for
immediate delivery. The Fund does not intend to make such purchases for
speculative purposes. During the period between the purchase and settlement, no
payment is made for the security and no interest accrues to the buyer from the
investment. There is a risk of loss to the Fund if the value of the security
declines prior to the settlement date.

|X| Puts and Stand-By Commitments. The Fund may acquire "stand-by
commitments" or "puts" with respect to municipal securities. The Fund would have
the right to sell specified securities at a set price on demand to the issuing
broker-dealer or bank. However, this feature may result in a lower interest rate
on the security. The Fund will acquire stand-by commitments or puts solely to
enhance portfolio liquidity.

|X| Illiquid Securities. Under the policies and procedures established by
the Fund's Board of Trustees, the Manager determines the liquidity of the Fund's
investments. Investments may be illiquid because of the absence of an active
trading market, making it difficult to value them or dispose of them promptly at
an acceptable price. The Fund will not invest more than 10% of its net assets in
illiquid securities (the Board may increase that limit to 15%). The Manager
monitors holdings of illiquid securities on an ongoing basis to determine
whether to sell any holdings to maintain adequate liquidity. The Fund cannot buy
a security that has a restriction on its resale.

|X| Hedging. The Fund may purchase and sell certain kinds of futures
contracts, put and call options, and options on futures and broadly-based
municipal bond indices, or enter into interest rate swap agreements. These are
all referred to as "hedging instruments." The Fund does not use hedging
instruments for speculative purposes, and has limits on its use of them. The
Fund does not use hedging instruments to a substantial degree and is not
required to use them in seeking its goal.

The Fund may buy and sell options and futures for a number of purposes. It
may do so to try to manage its exposure to the possibility that the prices of
its portfolio securities may decline, or to establish a position in the
securities market as a temporary substitute for purchasing individual
securities. It may do so to try to manage its exposure to changing interest
rates. Some of these strategies hedge the Fund's portfolio against price
fluctuations. Other hedging strategies, such as buying futures and call options,
tend to increase the Fund's exposure to the securities market.

If the Manager uses a hedging instrument at the wrong time or judges
market conditions incorrectly, the strategy may reduce the Fund's return. The
Fund could also experience losses if the prices of its futures and options
positions were not correlated with its other investments or if it could not
close out a position because of an illiquid market for the future or option.

Options trading involves the payment of premiums and has special tax
effects on the Fund. There are also special risks in particular hedging
strategies. For example, interest rate swaps are subject to credit risks (if the
other party fails to meet its obligations) and also to interest rate risks. The
Fund could be obligated to pay more under its swap agreements than it receives
under them, as a result of interest rate changes. The Fund may not enter into
swaps with respect to more than 25% of its total assets.

Temporary Defensive Investments. The Fund may invest up to 100% of its total
assets in temporary defensive investments from time to time. This may happen
during periods of unusual market conditions. Generally, they would be short-term
municipal securities, but could be U.S. government securities or highly-rated
corporate debt securities. The income from some of those temporary defensive
investments may not be tax-exempt, and therefore when making those investments
the Fund may not achieve its objective. The Fund may also hold these types of
temporary investments pending the investment of proceeds from the sale of Fund
shares or portfolio securities, or to meet anticipated redemptions of Fund
shares.

Year 2000 Risks. Because many computer software systems in use today cannot
distinguish the year 2000 from the year 1900, the markets for securities in
which the Fund invests could be detrimentally affected by computer failures
beginning January 1, 2000. Failure of computer systems used for securities
trading could result in settlement and liquidity problems for the Fund and other
investors. That failure could have a negative impact on handling securities
trades, pricing and accounting services. Data processing errors by government
issuers of securities could result in economic uncertainties, and those issuers
may incur substantial costs in attempting to prevent or fix such errors, all of
which could have a negative effect on the Fund's investments and returns.

The Manager, the Distributor and the Transfer Agent have been working on
necessary changes to their computer systems to deal with the year 2000 and
expect that their systems will be adapted in time for that event, although there
cannot be assurance of success. Additionally, the services they provide depend
on the interaction of their computer systems with those of brokers, information
services, the Fund's Custodian and other parties. Therefore, any failure of the
computer systems of those parties to deal with the year 2000 may also have a
negative affect on the services they provide to the Fund. The extent of that
risk cannot be ascertained at this time.

How the Fund is Managed

The Manager. The Fund's investment adviser is the Manager, OppenheimerFunds,
Inc., which is responsible for selecting the Fund's investments and handles its
day-to-day business. The Manager carries out its duties, subject to the policies
established by the Board of Trustees, under an Investment Advisory Agreement
which states the Manager's responsibilities. The Agreement sets forth the fees
paid by the Fund to the Manager and describes the expenses that the Fund is
responsible to pay to conduct its business.

The Manager has operated as an investment advisor since 1959. The Manager
(including subsidiaries) currently manages investment companies, including other
Oppenheimer funds, with assets of more than $85 billion as of September 30,
1998, and with more than 4 million shareholder accounts. The Manager is located
at Two World Trade Center, 34th Floor, New York, New York 10048-0203.

|X| Portfolio Manager. The Portfolio manager of the Fund is Robert
Patterson, a Senior Vice President of the Manager. Mr. Patterson is the
person principally responsible for the day-to-day management of the Fund's
portfolio, and has had this responsibility since September 18, 1989. Mr.
Patterson also serves as an officer and portfolio manager for other
Oppenheimer funds.

|X| Advisory Fees. Under the Investment Advisory Agreement, the Fund pays
the Manager an advisory fee at an annual rate which declines on additional
assets as the Fund grows: 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. The Fund's management fee for its
last fiscal year ended July 31, 1998, was 0.57% of average annual net assets for
Class A, Class B and Class C shares (after the Manager's waiver of a portion of
its fee).

About Your Account
- -------------------------------------------------------------------------------

How to Buy Shares

How Are Shares Purchased? You can buy shares several ways -- through any dealer,
broker or financial institution that has a sales agreement with the Fund's
Distributor, directly through the Distributor, or automatically through an Asset
Builder Plan under the OppenheimerFunds AccountLink service. The Distributor may
appoint certain servicing agents to accept purchase (and redemption) orders. The
Distributor, in its sole discretion, may reject any purchase order for the
Fund's shares.

|X| Buying Shares Through Your Dealer. Your dealer will place your
order with the Distributor on your behalf.

|X| Buying Shares Through the Distributor. Complete an OppenheimerFunds New
Account Application and return it with a check payable to "OppenheimerFunds
Distributor, Inc." Mail it to P.O. Box 5270, Denver, Colorado 80217. If you
don't list a dealer on the application, the Distributor will act as your agent
in buying the shares. However, we recommend that you discuss your investment
with a financial advisor before you make a purchase to be sure that the Fund is
appropriate for you.

|X| Buying Shares by Federal Funds Wire. Shares purchased through the
Distributor may be paid for by Federal Funds wire. The minimum investment is
$2,500. Before sending a wire, call the Distributor's Wire Department at
1-800-525-7048 to notify the Distributor of the wire, and to receive further
instructions.

|X| Buying Shares Through OppenheimerFunds AccountLink. With AccountLink,
shares are purchased for your account on the regular business day the
Distributor is instructed by you to initiate the Automated Clearing House (ACH)
transfer to buy the shares. You can provide those instructions automatically,
under an Asset Builder Plan, described below, or by telephone instructions using
OppenheimerFunds PhoneLink, also described below. Please refer to "AccountLink,"
below for more details.

|X| Buying Shares Through Asset Builder Plans. You may purchase shares of
the Fund (and up to four other Oppenheimer funds) automatically each month from
your account at a bank or other financial institution under an Asset Builder
Plan with AccountLink. Details are in the Asset Builder Application and the
Statement of Additional Information.

How Much Must You Invest? You can open a Fund account with a minimum initial
investment of $1,000 and make additional investments at any time with as little
as $25. There are reduced minimum investments under special investment plans.

|_| With Asset Builder Plans, Automatic Exchange Plans and military
allotment plans, you can make initial and subsequent investments for as little
as $25. Subsequent purchases of at least $25 can be made by telephone through
AccountLink.

|_| The minimum investment requirement does not apply to reinvesting
dividends from the Fund or other Oppenheimer funds (a list of them appears in
the Statement of Additional Information, or you can ask your dealer or call the
Transfer Agent), or reinvesting distributions from unit investment trusts that
have made arrangements with the Distributor.

At What Price Are Shares Sold? Shares are sold at their offering price (the net
asset value per share plus any initial sales charge that applies). The offering
price that applies to a purchase order is based on the next calculation of the
net asset value per share that is made after the Distributor receives the
purchase order at its offices in Denver, Colorado, or after any agent appointed
by the Distributor receives the order and sends it to the Distributor.

|_| The net asset value of each class of shares is determined as of the
close of The New York Stock Exchange, on each day the Exchange is open for
trading (referred to in this Prospectus as a "regular business day"). The
Exchange normally closes at 4:00 P.M., New York time, but may close earlier on
some days. (All references to time in this Prospectus mean "New York time").

The net asset value per share is determined by dividing the value of the
Fund's net assets attributable to a class by the number of shares of that class
that are outstanding. To determine net asset value, the Fund's Board of Trustees
has established procedures to value the Fund's securities, in general based on
market value. The Board has adopted special procedures for valuing illiquid
securities and obligations for which market values cannot be readily obtained.

|_| To receive the offering price for a particular day, in most cases the
Distributor or its designated agent must receive your order by the time of day
The New York Stock Exchange closes that day. If your order is received on a day
when the Exchange is closed or after it has closed, the order will receive the
next offering price that is determined after your order is received.

|_| If you buy shares through a dealer, your dealer must receive the order
by the close of The New York Stock Exchange and transmit it to the Distributor
so that it is received before the Distributor's close of business on a regular
business day (normally 5:00 P.M.) to receive that day's offering price.
Otherwise, the order will receive the next offering price that is determined.

- -------------------------------------------------------------------------------
What Classes of Shares Does the Fund Offer? The Fund offers investors three
different classes of shares. The different classes of shares represent
investments in the same portfolio of securities, but the classes are subject to
different expenses and will likely have different share prices. When you buy
shares, be sure to specify Class A, Class B or Class C shares. If you do not
choose a class, your investment will be made in Class A shares.
- -------------------------------------------------------------------------------
- -------------------------------------------------------------------------------

- -------------------------------------------------------------------------------
|X| Class A Shares. If you buy Class A shares, you pay an initial sales
charge (on investments up to $1 million). The amount of that sales charge will
vary depending on the amount you invest. The sales charge rates are listed in
"How Can I Buy Class A Shares?" below.

|X| Class B Shares. If you buy Class B shares, you pay no sales charge
at the time of purchase, but you will pay an annual asset-based sales charge,
and if you sell your shares within six years of buying them, you will
normally pay a contingent deferred sales charge. That sales charge varies
depending on how long you own your shares, as described in "How Can I Buy Class
B Shares?" below.
- -------------------------------------------------------------------------------

- -------------------------------------------------------------------------------
|X| Class C Shares. If you buy Class C shares, you pay no sales charge at
the time of purchase, but you will pay an annual asset-based sales charge, and
if you sell your shares within 12 months of buying them, you will normally pay a
contingent deferred sales charge of 1%, as described in "How Can I Buy Class C
Shares?" below.

Which Class of Shares Should You Choose? Once you decide that the Fund is an
appropriate investment for you, the decision as to which class of shares is best
suited to your needs depends on a number of factors that you should discuss with
your financial advisor. Some factors to consider are how much you plan to invest
and how long you plan to hold your investment. If your goals and objectives
change over time and you plan to purchase additional shares, you should
re-evaluate those factors to see if you should consider another class of shares.
The Fund's operating costs that apply to a class of shares and the effect of the
different types of sales charges on your investment will vary your investment
results over time.

The discussion below is not intended to be investment advice or a
recommendation, because each investor's financial considerations are different.
You should review these factors with your financial advisor. The discussion
below assumes that you will purchase only one class of shares, and not a
combination of shares of different classes.

|X| How Long Do You Expect to Hold Your Investment? While future financial
needs cannot be predicted with certainty, knowing how long you expect to hold
your investment will assist you in selecting the appropriate class of shares.
Because of the effect of class-based expenses, your choice will also depend on
how much you plan to invest. For example, the reduced sales charges available
for larger purchases of Class A shares may, over time, offset the effect of
paying an initial sales charge on your investment, compared to the effect over
time of higher class-based expenses on shares of Class B or Class C .

|_| Investing for the Short Term. If you have a relatively short-term
investment horizon (that is, you plan to hold your shares for not more than six
years), you should probably consider purchasing Class A or Class C shares rather
than Class B shares. That is because of the effect of the Class B contingent
deferred sales charge if you redeem within six years, as well as the effect of
the Class B asset-based sales charge on the investment return for that class in
the short-term. Class C shares might be the appropriate choice (especially for
investments of less than $100,000), because there is no initial sales charge on
Class C shares, and the contingent deferred sales charge does not apply to
amounts you sell after holding them one year.

However, if you plan to invest more than $100,000 for the shorter term,
then as your investment horizon increases toward six years, Class C shares might
not be as advantageous as Class A shares. That is because the annual asset-based
sales charge on Class C shares will have a greater impact on your account over
the longer term than the reduced front-end sales charge available for larger
purchases of Class A shares.

And for investors who invest $1 million or more, in most cases Class A
shares will be the most advantageous choice, no matter how long you intend to
hold your shares. For that reason, the Distributor normally will not accept
purchase orders of $500,000 or more of Class B shares or $1 million or more of
Class C shares from a single investor.

|_| Investing for the Longer Term. If you are investing less than $100,000
for the longer-term, for example for retirement, and do not expect to need
access to your money for seven years or more, Class B shares may be appropriate.

Of course, these examples are based on approximations of the effect of
current sales charges and expenses projected over time, and do not detail all of
the considerations in selecting a class of shares. You should analyze your
options carefully with your financial advisor before making that choice.

|X| Are There Differences in Account Features That Matter to You? Some
account features (such as checkwriting) may not be available to Class B or Class
C shareholders. Other features (such as Automatic Withdrawal Plans) may not be
advisable (because of the effect of the contingent deferred sales charge) for
Class B or Class C shareholders. Therefore, you should carefully review how you
plan to use your investment account before deciding which class of shares to
buy. Additionally, the dividends payable to Class B and Class C shareholders
will be reduced by the additional expenses borne by those classes that are not
borne by Class A shares, such as the Class B and Class C asset-based sales
charge described below and in the Statement of Additional Information. Share
certificates are not available for Class B and Class C shares, and if you are
considering using your shares as collateral for a loan, that may be a factor to
consider.

|X| How Does It Affect Payments to My Broker? A salesperson, such as a
broker, may receive different compensation for selling one class of shares than
for selling another class. It is important to remember that Class B and Class C
contingent deferred sales charges and asset-based sales charges have the same
purpose as the front-end sales charge on sales of Class A shares: to compensate
the Distributor for commissions and expenses it pays to dealers and financial
institutions for selling shares. The Distributor may pay additional compensation
from its own resources to securities dealers or financial institutions based
upon the value of shares of the Fund owned by the dealer or financial
institution for its own account or for its customers.

Special Sales Charge Arrangements and Waivers. The Statement of Additional
Information details the conditions for the waiver of sales charges that apply in
certain cases, and the special sales charge rates that apply to purchases of
shares of the Fund by certain groups, or under specified retirement plan
arrangements or in other special types of transactions.

How Can I Buy Class A Shares? Class A shares are sold at their offering price,
which is normally net asset value plus an initial sales charge. However, in some
cases, described below, purchases are not subject to an initial sales charge,
and the offering price will be the net asset value. In other cases, reduced
sales charges may be available, as described below or in the Statement of
Additional Information. Out of the amount you invest, the Fund receives the net
asset value to invest for your account.

The sales charge varies depending on the amount of your purchase. A
portion of the sales charge may be retained by the Distributor or allocated to
your dealer as commission. The Distributor reserves the right to reallow the
entire commission to dealers. The current sales charge rates and commissions
paid to dealers and brokers are as follows:

- ----------------------------------------------------------------------
Front-End Sales Front-End
Sales Commission As a
Charge As a Charge As
a Percentage of
Percentage of Percentage of Net Offering
Amount of Purchase Offering Price Amount Invested Price
- ----------------------------------------------------------------------

Less than $50,000 4.75% 4.98% 4.00%
- ----------------------------------------------------------------------

$50,000 or more but 4.50% 4.71% 4.00%
less than $100,000
- ----------------------------------------------------------------------
- ----------------------------------------------------------------------

$100,000 or more but 3.50% 3.63% 3.00%
less than $250,000
- ----------------------------------------------------------------------
- ----------------------------------------------------------------------

$250,000 or more but 2.50% 2.56% 2.25%
less than $500,000
- ----------------------------------------------------------------------
- ----------------------------------------------------------------------

$500,000 or more but 2.00% 2.04% 1.80%
less than $1 million
- ----------------------------------------------------------------------

|X| Class A Contingent Deferred Sales Charge. There is no initial sales
charge on purchases of Class A shares of any one or more of the Oppenheimer
funds aggregating $1 million or more. The Distributor pays dealers of record
commissions in an amount equal to 1.0% of purchases of $1 million or more other
than by retirement accounts. That commission will be paid only on purchases that
were not previously subject to a front-end sales charge and dealer commission.

If you redeem any of those shares within 18 months of the end of the
calendar month of their purchase, a contingent deferred sales charge (called the
"Class A contingent deferred sales charge") may be deducted from the redemption
proceeds. That sales charge will be equal to 1.0% of the lesser of (1) the
aggregate net asset value of the redeemed shares at the time of redemption
(excluding shares purchased by reinvestment of dividends or capital gain
distributions) or (2) the original net asset value of the redeemed shares.
However, the Class A contingent deferred sales charge will not exceed the
aggregate amount of the commissions the Distributor paid to your dealer on all
purchases of Class A shares of all Oppenheimer funds you made that were subject
to the Class A contingent deferred sales charge.

In determining whether a contingent deferred sales charge is payable when
shares are redeemed, the Fund will first redeem shares that are not subject to
the sales charge, including shares purchased by reinvestment of dividends and
capital gains. Then the Fund will redeem other shares in the order in which you
purchased them. The Class A contingent deferred sales charge is waived in
certain cases described in "Waivers of Class A Sales Charges" in the Statement
of Additional Information.

The Class A contingent deferred sales charge is not charged on exchanges
of shares under the Fund's Exchange Privilege (described below). However, if the
shares acquired by exchange are redeemed within 18 calendar months of the end of
the calendar month in which the exchanged shares were originally purchased, then
the sales charge will apply.

How Can I Reduce Sales Charges for Class A Share Purchases? You may be eligible
to buy Class A shares at reduced sales charge rates under the Fund's "Right of
Accumulation" or a Letter of Intent, as described in "Reduced Sales Charges" in
the Statement of Additional Information.

|X| Waivers of Class A Sales Charges. The Class A initial and contingent
deferred sales charges are not imposed in the circumstances described in
"Reduced Sales Charges" in the Statement of Additional Information. In order to
receive a waiver of the Class A contingent deferred sales charge, you must
notify the Transfer Agent when purchasing shares whether any of the special
conditions apply.

How Can I Buy Class B Shares? Class B shares are sold at net asset value per
share without an initial sales charge. However, if Class B shares are redeemed
within 6 years of their purchase, a contingent deferred sales charge will be
deducted from the redemption proceeds. The Class B contingent deferred sales
charge is paid to compensate the Distributor for its expenses of providing
distribution-related services to the Fund in connection with the sale of Class B
shares.

The contingent deferred sales charge will be based on the lesser of the
net asset value of the redeemed shares at the time of redemption or the original
net asset value. The contingent deferred sales charge is not imposed on:
|_| the amount of your account value represented by an increase in net
asset value over the initial purchase price, |_| shares purchased by the
reinvestment of dividends or capital gains distributions, or |_| shares
redeemed in the special circumstances described in the Appendix in the
Statement of Additional Information.

To determine whether the contingent deferred sales charge applies to a
redemption, the Fund redeems shares in the following order: (1) shares acquired
by reinvestment of dividends and capital gains
distributions,
(2) shares held for over 6 years, and
(3) shares held the longest during the 6-year period.

The amount of the contingent deferred sales charge will depend on the
number of years since you invested and the dollar amount being redeemed,
according to the following schedule:

- ----------------------------------------------------------------------
Years Since Beginning of Contingent Deferred Sales Charge
Month in which Purchase On Redemptions in That Year
Order Was Accepted (As % of Amount Subject to Charge)
- ----------------------------------------------------------------------
- ----------------------------------------------------------------------

0-1 5.0%
- ----------------------------------------------------------------------
- ----------------------------------------------------------------------

1-2 4.0%
- ----------------------------------------------------------------------
- ----------------------------------------------------------------------

2-3 3.0%
- ----------------------------------------------------------------------
- ----------------------------------------------------------------------

3-4 3.0%
- ----------------------------------------------------------------------
- ----------------------------------------------------------------------

4-5 2.0%
- ----------------------------------------------------------------------
- ----------------------------------------------------------------------

5-6 1.0%
- ----------------------------------------------------------------------
- ----------------------------------------------------------------------

6 and following None
- ----------------------------------------------------------------------

In the table, a "year" is a 12-month period. In applying the sales charge, all
purchases are considered to have been made on the first regular business day of
the month in which the purchase was made.

|X| Automatic Conversion of Class B Shares. Class B shares automatically
convert to Class A shares 72 months after you purchase them. This conversion
feature relieves Class B shareholders of the asset-based sales charge that
applies to Class B shares under the Class B Distribution and Service Plan,
described below. The conversion is based on the relative net asset value of the
two classes, and no sales load or other charge is imposed. When Class B shares
convert, any other Class B shares that were acquired by the reinvestment of
dividends and distributions on the converted shares will also convert to Class A
shares. The conversion feature is subject to the continued availability of a tax
ruling described in the Statement of Additional Information.

How Can I Buy Class C Shares? Class C shares are sold at net asset value per
share without an initial sales charge. However, if Class C shares are redeemed
within 12 months of their purchase, a contingent deferred sales charge of 1.0%
will be deducted from the redemption proceeds. The Class C contingent deferred
sales charge is paid to compensate the Distributor for its expenses of providing
distribution-related services to the Fund in connection with the sale of Class C
shares.

|_| the amount of your account value represented by the increase in net
asset value over the initial purchase price
|_| shares purchased by the reinvestment of dividends or capital gains
distributions, or
|_| shares redeemed in the special circumstances described in the Appendix
to the Statement of Additional Information.

To determine whether the contingent deferred sales charge applies to a
redemption, the Fund redeems shares in the following order: (1) shares acquired
by reinvestment of dividends and capital gains
distributions,
(2) shares held for over 12 months, and
(3) shares held the longest during the 12-month period.

Distribution and Service (12b-1) Plans.

|X| Service Plan for Class A Shares. The Fund has adopted a Service Plan
for Class A shares. It reimburses the Distributor for a portion of its costs
incurred for services provided to accounts that hold Class A shares.
Reimbursement is made quarterly at an annual rate of up to 0.15% of the average
annual net assets of Class A shares of the Fund. The Distributor currently uses
all of those fees to compensate dealers, brokers, banks and other financial
institutions quarterly for providing personal service and maintenance of
accounts of their customers that hold Class A shares.

|X| Distribution and Service Plans for Class B and Class C Shares. The
Fund has adopted Distribution and Service Plans for Class B and Class C shares
to compensate the Distributor for its services and costs in distributing Class B
and Class C shares and servicing accounts. Under the plans, the Fund pays the
Distributor an annual "asset-based sales charge" of 0.75% per year on Class B
shares and on Class C shares. The Distributor also receives a service fee of
0.15% per year under each plan.

The asset-based sales charge and service fees increase Class B and Class C
expenses by up to 0.90% of the net assets per year of the respective class.
Because these fees are paid out of the Fund's assets on an on-going basis, over
time these fees will increase the cost of your investment and may cost you more
than other types of sales charges.

The Distributor uses the service fees to compensate dealers for providing
personal services for accounts that hold Class B or Class C shares. The
Distributor pays the 0.15% service fees to dealers in advance for the first year
after the shares were sold by the dealer. After the shares have been held for a
year, the Distributor pays the service fees to dealers on a quarterly basis.

The Distributor currently pays sales commission of 3.85% of the purchase
price of Class B shares to dealers from its own resources at the time of sale.
Including the advance of the service fee, the total amount paid by the
Distributor to the dealer at the time of sales of Class B shares is therefore
4.00% of the purchase price. The Distributor retains the Class B asset-based
sales charge.

The Distributor currently pays sales commissions of 0.75% of the purchase
price of Class C shares to dealers from its own resources at the time of sale.
Including the advance of the service fee, the total amount paid by the
Distributor to the dealer at the time of sale of Class C shares is therefore
0.90% of the purchase price. The Distributor plans to pay the asset-based sales
charge as an ongoing commission to the dealer on Class C shares that have been
outstanding for a year or more.

service is not available within 30 days of changing the address on an account.

|X| Telephone Redemptions Through AccountLink. There are no dollar limits
on telephone redemption proceeds sent to a bank account designated when you
establish AccountLink. Normally the ACH transfer to your bank is initiated on
the business day after the redemption. You do not receive dividends on the
proceeds of the shares you redeemed while they are waiting to be transferred.

|_| Checks can be written to the order of whomever you wish, but may not
be cashed at the Fund's bank or Custodian.
|_| Checkwriting privileges are not available for accounts holding Class B
shares or Class C shares, or Class A shares that are subject to a contingent
deferred sales charge.
|_| Checks must be written for at least $100.
|_| Checks cannot be paid if they are written for more than your account
value. Remember: your shares fluctuate in value and you should not write a
check close to the total account value.
|_| You may not write a check that would require the Fund to redeem shares
that were purchased by check or Asset Builder Plan payments within the prior 10
days.
|_| Don't use your checks if you changed your Fund account number, until
you receive new checks.

Can I Sell Shares Through My Dealer? The Distributor has made arrangements to
repurchase Fund shares from dealers and brokers on behalf of their customers.
Brokers or dealers may charge for that service. If your shares are held in the
name of your dealer, you must redeem them through your dealer.

How to Exchange Shares

Shares of the Fund may be exchanged for shares of certain Oppenheimer funds at
net asset value per share at the time of exchange, without sales charge.
To exchange shares, you must meet several conditions:
|_| Shares of the fund selected for exchange must be available for sale in
your state of residence.
|_| The prospectuses of this Fund and the fund whose shares you want to
buy must offer the exchange privilege.
|_| You must hold the shares you buy when you establish your account for
at least 7 days before you can exchange them. After the account is open 7 days,
you can exchange shares every regular business day.
|_| You must meet the minimum purchase requirements for the fund you
purchase by exchange.
|_| Before exchanging into a fund, you should obtain and read its
prospectus.

Shares of a particular class of the Fund may be exchanged only for shares
of the same class in the other Oppenheimer funds. For example, you can exchange
Class A shares of this Fund only for Class A shares of another fund. In some
cases, sales charges may be imposed on exchange transactions. For tax purposes,
exchanges of shares involve a sale of the shares of the fund you own and a
purchase of the shares of the other fund, which may result in a capital gain or
loss. Please refer to "How to Exchange Shares" in the Statement of Additional
Information for more details.

How Do I Submit Exchange Requests? Exchanges may be requested in writing or
by telephone:

|X| Written Exchange Requests. Submit an OppenheimerFunds Exchange
Request form, signed by all owners of the account. Send it to the Transfer
Agent at the address on the Back Cover.

|X| Telephone Exchange Requests. Telephone exchange requests may be made
either by calling a service representative at 1-800-852-8457, or by using
PhoneLink for automated exchanges by calling 1-800-533-3310. Telephone exchanges
may be made only between accounts that are registered with the same name(s) and
address. Shares held under certificates may not be exchanged by telephone.

You can find a list of Oppenheimer funds currently available for exchanges
in the Statement of Additional Information or obtain one by calling a service
representative at 1-800-525-7048. That list can change from time to time.

Are There Limitations on Exchanges? There are certain exchange policies you
should be aware of:
|_| Shares are normally redeemed from one fund and purchased from the
other fund in the exchange transaction on the same regular business day on which
the Transfer Agent receives an exchange request that conforms to the policies
described above. It must be received by the close of The New York Stock Exchange
that day, which is normally 4:00 P.M. but may be earlier on some days. However,
either fund may delay the purchase of shares of the fund you are exchanging into
up to seven days if it determines it would be disadvantaged by a same-day
exchange. For example, the receipt of multiple exchange requests from a "market
timer" might require the Fund to sell securities at a disadvantageous time
and/or price.
|_| Because excessive trading can hurt fund performance and harm
shareholders, the Fund reserves the right to refuse any exchange request that it
believes will disadvantage it, or to refuse multiple exchange requests submitted
by a shareholder or dealer.
|_| The Fund may amend, suspend or terminate the exchange privilege at any
time. Although the Fund will attempt to provide you notice whenever it is
reasonably able to do so, it may impose these changes at any time.
|_| If the Transfer Agent cannot exchange all the shares you request
because of a restriction cited above, only the shares eligible for exchange will
be exchanged.

Shareholder Account Rules and Policies

|X| The offering of shares may be suspended during any period in which the
determination of net asset value is suspended, and the offering may be suspended
by the Board of Trustees at any time the Board believes it is in the Fund's best
interest to do so.

|X| Telephone Transaction Privileges for purchases, redemptions or
exchanges may be modified, suspended or terminated by the Fund at any time. If
an account has more than one owner, the Fund and the Transfer Agent may rely on
the instructions of any one owner. Telephone privileges apply to each owner of
the account and the dealer representative of record for the account unless the
Transfer Agent receives cancellation instructions from an owner of the account.

|X| The Transfer Agent will record any telephone calls to verify data
concerning transactions and has adopted other procedures to confirm that
telephone instructions are genuine, by requiring callers to provide tax
identification numbers and other account data or by using PINs, and by
confirming such transactions in writing. The Transfer Agent and the Fund will
not be liable for losses or expenses arising out of telephone instructions
reasonably believed to be genuine.

|X| Redemption or transfer requests will not be honored until the Transfer
Agent receives all required documents in proper form. From time to time, the
Transfer Agent in its discretion may waive certain of the requirements for
redemptions stated in this Prospectus.

|X| Dealers that can perform account transactions for their clients by
participating in NETWORKING through the National Securities Clearing Corporation
are responsible for obtaining their clients' permission to perform those
transactions, and are responsible to their clients who are shareholders of the
Fund if the dealer performs any transaction erroneously or improperly.

|X| The redemption price for shares will vary from day to day because the
value of the securities in the Fund's portfolio fluctuates. The redemption
price, which is the net asset value per share, will normally differ for Class A,
Class B and Class C shares. The redemption value of your shares may be more or
less than their original cost.

|X| Payment for redeemed shares ordinarily is made in cash. It is
forwarded by check or through AccountLink (as elected by the shareholder) within
seven days after the Transfer Agent receives redemption instructions in proper
form. However, under unusual circumstances determined by the Securities and
Exchange Commission, payment may be delayed or suspended. For accounts
registered in the name of a broker-dealer, payment will normally be forwarded
within three business days after redemption.

|X| The Transfer Agent may delay forwarding a check or processing a
payment via AccountLink for recently purchased shares, but only until the
purchase payment has cleared. That delay may be as much as 10 days from the date
the shares were purchased. That delay may be avoided if you purchase shares by
Federal Funds wire or certified check, or arrange with your bank to provide
telephone or written assurance to the Transfer Agent that your purchase payment
has cleared.

|X| Involuntary redemptions of small accounts may be made by the Fund if
the account value has fallen below $200 for reasons other than the fact that the
market value of shares has dropped. In some cases involuntary redemptions may be
made to repay the Distributor for losses from the cancellation of share purchase
orders.

|X| Shares may be "redeemed in kind" under unusual circumstances (such as
a lack of liquidity in the Fund's portfolio to meet redemptions). This means
that the redemption proceeds will be paid with securities from the Fund's
portfolio.

|X| "Backup Withholding" of federal income tax may be applied against
taxable dividends, distributions and redemption proceeds (including exchanges)
if you fail to furnish the Fund your correct, certified Social Security or
Employer Identification Number when you sign your application, or if you
under-report your income to the Internal Revenue Service.

|X| To avoid sending duplicate copies of materials to households, the Fund
will mail only one copy of each annual and semi-annual report to shareholders
having the same last name and address on the Fund's records. However, each
shareholder may call the Transfer Agent at 1-800-525-7048 to ask that copies of
those materials be sent personally to that shareholder.

Dividends and Tax Information

Dividends. The Fund intends to declare dividends separately for Class A, Class B
and Class C shares from net tax-exempt income and/or net investment income each
regular business day and to pay those dividends to shareholders monthly on a
date selected by the Board of Trustees. Daily dividends will not be declared or
paid on newly purchased shares until Federal Funds are available to the Fund
from the purchase payment for such shares.

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 level at any time, without prior notice to
shareholders. Additionally, the amount of those dividends and the distributions
paid on class B and 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 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.

Capital Gains. Although the Fund does not seek capital gains, it may realize
capital gains on the sale of portfolio securities. If it does, it may make
distributions out of any net short-term or long-term capital gains in December
of each year. The Fund may make supplemental distributions of dividends and
capital gains following the end of its fiscal year. Long-term capital gains will
be separately identified in the tax information the Fund sends you after the end
of the calendar year.

What Choices Do I Have for Receiving Distributions? When you open your account,
specify on your application how you want to receive your dividends and
distributions. You have four options:

|X| Reinvest All Distributions in the Fund. You can elect to reinvest
all dividends and long-term capital gains distributions in additional shares
of the Fund.

|X| Reinvest Long-Term Capital Gains Only. You can elect to reinvest
long-term capital gains distributions in the Fund while receiving dividends by
check or having them sent to your bank account through AccountLink.

|X| Receive All Distributions in Cash. You can elect to receive a check
for all dividends and long-term capital gains distributions or have them sent to
your bank through AccountLink.

|X| Reinvest Your Distributions in Another OppenheimerFunds Account.
You can reinvest all distributions in the same class of shares of another
Oppenheimer fund account you have established.

Taxes. Dividends paid from net investment income earned by the Fund on municipal
securities will be excludable from gross income for Federal income tax purposes.
A portion of a dividend that is derived from interest paid on certain "private
activity bonds" may be an item of tax preference if you are subject to the
alternative minimum tax. If the Fund earns interest on taxable investments, any
dividends derived from those earnings will be taxable as ordinary income to
shareholders.

Dividends paid by the Fund from interest on Pennsylvania municipal
securities will be exempt from Pennsylvania personal income taxes, and for
Philadelphia residents, from the investment income tax of the School District of
Philadelphia. Dividends paid from income from municipal securities of issuers
outside Pennsylvania will normally be subject to Pennsylvania individual income
taxes.

Shares of the Fund will be exempt from Pennsylvania county personal
property taxes to the extent that the Fund's portfolio securities consist of
Pennsylvania municipal securities on the annual assessment date.

Dividends and capital gains distributions may be subject to state or local
taxes. Long-term capital gains are taxable as long-term capital gains when
distributed to shareholders, and may be taxable at different rates depending on
how long the Fund holds the asset. It does not matter how long you have held
your shares. Dividends paid from short-term capital gains are taxable as
ordinary income. Whether you reinvest your distributions in additional shares or
take them in cash, the tax treatment is the same. Every year the Fund will send
you and the IRS a statement showing the amount of any taxable distribution you
received in the previous year as well as the amount of your tax-exempt income.

|X| Remember There May be Taxes on Transactions. Even though the Fund
seeks to distribute tax-exempt income to shareholders, you may have a capital
gain or loss when you sell or exchange your shares. A capital gain or loss is
the difference between the price you paid for the shares and the price you
received when you sold them. Any capital gain is subject to capital gains tax.

|X| Returns of Capital Can Occur. In certain cases, distributions made
by the Fund may be considered a non-taxable return of capital to
shareholders. If that occurs, it will be identified in notices to
shareholders.

This information is only a summary of certain federal and Pennsylvania tax
information about your investment. You should consult with your tax adviser
about the effect of an investment in the Fund on your particular tax situation.

Financial Highlights

The Financial Highlights Table is presented to help you understand the Fund's
financial performance for the past 5 fiscal years. Certain information reflects
financial results for a single Fund share. The total returns in the table
represent the rate that an investor would have earned [or lost] on an investment
in the Fund (assuming reinvestment of all dividends and distributions). This
information has been audited by KPMG Peat Marwick LLP, the Fund's independent
auditors, whose report, along with the Fund's financial statements, is included

ABOUT THE FUND
- -------------------------------------------------------------------------------

Additional Information About the Fund's Investment Policies and Risks

The investment objective and the principal investment policies of the Fund
are described in the Prospectus. This Statement of Additional Information
contains supplemental information about those policies and the types of
securities that the Fund's investment Manager, OppenheimerFunds, Inc., will
select for the Fund. Additional explanations are also provided about the
strategies the Fund may use to try to achieve its objective.

The Fund's Investment Policies. The Fund does not make investments with the
objective of seeking capital growth, since that would generally be inconsistent
with its goal of seeking tax-exempt income. However, the value of the securities
held by the Fund may be affected by changes in general interest rates. Because
the current value of debt securities varies inversely with changes in prevailing
interest rates, if interest rates increased after a security was purchased, that
security would normally decline in value. Conversely, should interest rates
decrease after a security was purchased, normally its value would rise.

However, those fluctuations in value will not generally result in realized
gains or losses to the Fund unless the Fund sells the security prior to
maturity. A debt security held to maturity is redeemable by its issuer at full
principal value plus accrued interest. The Fund does not usually intend to
dispose of securities prior to their maturity, but may do so for liquidity, or
because of other factors affecting the issuer that cause the Manager to sell the
particular security. In that case, the Fund could experience a capital gain or
loss on the sale.

There are variations in the credit quality of municipal securities, both
within a particular rating classification and between classifications. These
variations depend on numerous factors. The yields of municipal securities depend
on a number of factors, including general conditions in the municipal securities
market, the size of a particular offering, the maturity of the obligation and
rating (if any) of the issue. These factors are discussed in greater detail
below.

Portfolio Turnover. A change in the securities held by the Fund from
buying and selling investments is known as "portfolio turnover." Short-term
trading increases the rate of portfolio turnover and could increase the Fund's
transaction costs. However, the Fund ordinarily incurs little or no brokerage
expense because most of the Fund's portfolio transactions are principal trades
that do not require payment of brokerage commissions.

The Fund ordinarily does not trade securities to achieve short-term
capital gains, because they would not be tax-exempt income. To a limited degree,
the Fund may engage in short-term trading to attempt to take advantage of
short-term market variations. It may also do so to dispose of a portfolio
security prior to its maturity. That might be done if, on the basis of a revised
credit evaluation of the issuer or other considerations, the Fund believes such
disposition advisable or it needs to generate cash to satisfy requests to redeem
Fund shares. In those cases, the Fund may realize a capital gain or loss on its
investments. The Fund's annual portfolio turnover rate normally is not expected
to exceed 100%.

Municipal Securities. The types of municipal securities in which the Fund may
invest are described in the Prospectus under "About the Fund's Investments."
Municipal securities are generally classified as general obligation bonds,
revenue bonds and notes. A discussion of the general characteristics of these
principal types of municipal securities follows below.

|X| Municipal Bonds. We have classified longer term municipal securities
as "municipal bonds." The principal classifications of long-term municipal bonds
are "general obligation" and "revenue" (including "industrial development")
bonds. They may have fixed, variable or floating rates of interest, as described
below.

Some bonds may be "callable," allowing the issuer to redeem them before
their maturity date. To protect bondholders, callable bonds may be issued with
provisions that prevent them from being called for a period of time. Typically,
that is 5 to 10 years from the issuance date. When interest rates decline, if
the call provision of a bond has expired, it is more likely that the issuer may
call the bond. If that occurs, the Fund might have to reinvest the proceeds of
the called bond in bonds that have a lower rate of return.

|_| General Obligation Bonds. The basic security behind general
obligation bonds is the issuer's pledge of its full faith and credit and taxing
power, if any, for the repayment of principal and the payment of interest.
Issuers of general obligation bonds include states, counties, cities, towns, and
regional districts. The proceeds of these obligations are used to fund a wide
range of public projects, including construction or improvement of schools,
highways and roads, and water and sewer systems. The rate of taxes that can be
levied for the payment of debt service on these bonds may be limited or
unlimited. Additionally, there may be limits as to the rate or amount of special
assessments that can be levied to meet these obligations.

|_| Revenue Bonds. The principal security for a revenue bond is
generally the net revenues derived from a particular facility, group of
facilities, or, in some cases, the proceeds of a special excise tax or other
specific revenue source. Revenue bonds are issued to finance a wide variety of
capital projects. Examples include electric, gas, water and sewer systems;
highways, bridges, and tunnels; port and airport facilities; colleges and
universities; and hospitals.

Although the principal security for these types of bonds may vary
from bond to bond, many provide additional security in the form of a debt
service reserve fund that may be used to make principal and interest payments on
the issuer's obligations. Housing finance authorities have a wide range of
security, including partially or fully insured mortgages, rent subsidized and/or
collateralized mortgages, and/or the net revenues from housing or other public
projects. Some authorities provide further security in the form of a state's
ability (without obligation) to make up deficiencies in the debt service reserve
fund.

|_| Industrial Development Bonds. Industrial development bonds are
considered municipal bonds if the interest paid is exempt from federal income
tax. They are issued by or on behalf of public authorities to raise money to
finance various privately operated facilities for business and manufacturing,
housing, sports, and pollution control. These bonds may also be used to finance
public facilities such as airports, mass transit systems, ports, and parking.
The payment of the principal and interest on such bonds is dependent solely on
the ability of the facility's user to meet its financial obligations and the
pledge, if any, of real and personal property financed by the bond as security
for those payments.

|_| Private Activity Municipal Securities. The Tax Reform Act of 1986
(the "Tax Reform Act") reorganized, as well as amended, the rules governing tax
exemption for interest on certain types of municipal securities. The Tax Reform
Act generally did not change the tax treatment of bonds issued in order to
finance governmental operations. Thus, interest on general obligation bonds
issued by or on behalf of state or local governments, the proceeds of which are
used to finance the operations of such governments, continues to be tax-exempt.
However, the Tax Reform Act limited the use of tax-exempt bonds for
non-governmental (private) purposes. More stringent restrictions were placed on
the use of proceeds of such bonds. Interest on certain private activity bonds is
taxable under the revised rules. There is an exception for "qualified"
tax-exempt private activity bonds, for example, exempt facility bonds including
certain industrial development bonds, qualified mortgage bonds, qualified
Section 501(c)(3) bonds, and qualified student loan bonds.

In addition, limitations as to the amount of private activity bonds which
each state may issue were revised downward by the Tax Reform Act, which will
reduce the supply of such bonds. The value of the Fund's portfolio could be
affected if there is a reduction in the availability of such bonds.

Interest on certain private activity bonds issued after August 7, 1986,
which continues to be tax-exempt, will be treated as a tax preference item
subject to the alternative minimum tax (discussed below) to which certain
taxpayers are subject. The Fund may hold municipal securities the interest on
which (and thus a proportionate share of the exempt-interest dividends paid by
the Fund) will be subject to the Federal alternative minimum tax on individuals
and corporations. There are no limits on the amount of assets the Fund may
invest in private activity securities.

The Federal alternative minimum tax is designed to ensure that all persons
who receive income pay some tax, even if their regular tax is zero. This is
accomplished in part by including in taxable income certain tax preference items
that are used to calculate alternative minimum taxable income. The Tax Reform
Act made tax-exempt interest from certain private activity bonds a tax
preference item for purposes of the alternative minimum tax on individuals and
corporations. Any exempt-interest dividend paid by a regulated investment
company will be treated as interest on a specific private activity bond to the
extent of the proportionate relationship the interest the investment company
receives on such bonds bears to all its exempt interest dividends.

In addition, corporate taxpayers subject to the alternative minimum tax
may, under some circumstances, have to include exempt-interest dividends in
calculating their alternative minimum taxable income. That could occur in
situations where the "adjusted current earnings" of the corporation exceeds its
alternative minimum taxable income.

To determine whether a municipal security is treated as a taxable private
activity bond, it is subject to a test for: (a) a trade or business use and
security interest, or (b) a private loan restriction. Under the trade or
business use and security interest test, an obligation is a private activity
bond if: (i) more than 10% of the bond proceeds are used for private business
purposes and (ii) 10% or more of the payment of principal or interest on the
issue is directly or indirectly derived from such private use or is secured by
the privately used property or the payments related to the use of the property.
For certain types of uses, a 5% threshold is substituted for this 10% threshold.

The term "private business use" means any direct or indirect use in a
trade or business carried on by an individual or entity other than a state or
municipal governmental unit. Under the private loan restriction, the amount of
bond proceeds that may be used to make private loans is limited to the lesser of
5% or $5.0 million of the proceeds. Thus, certain issues of municipal securities
could lose their tax-exempt status retroactively if the issuer fails to meet
certain requirements as to the expenditure of the proceeds of that issue or the
use of the bond-financed facility. The Fund makes no independent investigation
of the users of such bonds or their use of proceeds of the bonds. If the Fund
should hold a bond that loses its tax-exempt status retroactively, there might
be an adjustment to the tax-exempt income previously distributed to
shareholders.

Additionally, a private activity bond that would otherwise be a qualified
tax-exempt private activity bond will not, under Internal Revenue Code Section
147(a), be a qualified bond for any period during which it is held by a person
who is a "substantial user" of the facilities or by a "related person" of such a
substantial user. This "substantial user" provision applies primarily to exempt
facility bonds, including industrial development bonds. The Fund may invest in
industrial development bonds and other private activity bonds. Therefore, the
Fund may not be an appropriate investment for entities which are "substantial
users" (or persons related to "substantial users") of such exempt facilities.
Those entities and persons should consult their tax advisers before purchasing
shares of the Fund.

A "substantial user" of such facilities is defined generally as a
"non-exempt person who regularly uses part of a facility" financed from the
proceeds of exempt facility bonds. Generally, an individual will not be a
"related person" under the Internal Revenue Code unless such individual or the
individual's immediate family (spouse, brothers, sisters and immediate
descendants) own directly or indirectly in the aggregate more than 50% in value
of the equity of a corporation or partnership which is a "substantial user" of a
facility financed from the proceeds of exempt facility bonds.

|X| Municipal Notes. Municipal securities having a maturity (when the
security is issued) of less than one year are generally known as municipal
notes. Municipal notes generally are used to provide for short-term working
capital needs. Some of the types of municipal notes the Fund can invest in are
described below.

|_| Tax Anticipation Notes. These are issued to finance working capital
needs of municipalities. Generally, they are issued in anticipation of various
seasonal tax revenue, such as income, sales, use or other business taxes, and
are payable from these specific future taxes.

|_| Revenue Anticipation Notes. These are notes issued in expectation
of receipt of other types of revenue, such as Federal revenues available
under Federal revenue-sharing programs.

|_| Bond Anticipation Notes. Bond anticipation notes are issued to provide
interim financing until long-term financing can be arranged. The long-term bonds
that are issued typically also provide the money for the repayment of the notes.

|_| Construction Loan Notes. These are sold to provide project
construction financing until permanent financing can be secured. After
successful completion and acceptance of the project, it may receive permanent
financing through public agencies, such as the Federal Housing Administration.

|X| Tax Exempt Commercial Paper. This type of short-term obligation
(usually having a maturity of 270 days or less) is issued by a municipality
to meet current working capital needs.

|X| Municipal Lease Obligations. The Fund's investments in municipal lease
obligations may be through certificates of participation that are offered to
investors by public entities. Municipal leases may take the form of a lease or
an installment purchase contract issued by a state or local government authority
to obtain funds to acquire a wide variety of equipment and facilities.

Some municipal lease securities may be deemed to be "illiquid" securities.
Their purchase by the Fund would be limited as described below in "Illiquid
Securities." From time to time the Fund may invest more than 5% of its net
assets in municipal lease obligations that the Manager has determined to be
liquid under guidelines set by the Board of Trustees.

Those guidelines require the Manager to evaluate: |_| the frequency of
trades and price quotations for such securities; |_| the number of dealers
or other potential buyers willing to purchase or sell such securities; |_|
the availability of market-makers; and |_| the nature of the trades for
such securities.

While the Fund holds such securities, the Manager will also evaluate the
likelihood of a continuing market for these securities and their credit quality.

Municipal leases have special risk considerations. Although lease
obligations do not constitute general obligations of the municipality for which
the municipality's taxing power is pledged, a lease obligation is ordinarily
backed by the municipality's covenant to budget for, appropriate and make the
payments due under the lease obligation. However, certain lease obligations
contain "non-appropriation" clauses which provide that the municipality has no
obligation to make lease or installment purchase payments in future years unless
money is appropriated for that purpose on a yearly basis. While the obligation
might be secured by the lease, it might be difficult to dispose of that property
in case of a default.

Projects financed with certificates of participation generally are not
subject to state constitutional debt limitations or other statutory requirements
that may apply to other municipal securities. Payments by the public entity on
the obligation underlying the certificates are derived from available revenue
sources. That revenue might be diverted to the funding of other municipal
service projects. Payments of interest and/or principal with respect to the
certificates are not guaranteed and do not constitute an obligation of a state
or any of its political subdivisions.

In addition to the risk of "non-appropriation," municipal lease securities
do not have as highly liquid a market as conventional municipal bonds. Municipal
leases, like other municipal debt obligations, are subject to the risk of
non-payment of interest or repayment of principal by the issuer. The ability of
issuers of municipal leases to make timely lease payments may be adversely
affected in general economic downturns and as relative governmental cost burdens
are reallocated among federal, state and local governmental units. A default in
payment of income would result in a reduction of income to the Fund. It could
also result in a reduction in the value of the municipal lease and that, as well
as a default in repayment of principal, could result in a decrease in the net
asset value of the Fund.

|X| Ratings of Municipal Securities. Ratings by ratings organizations such
as Moody's Investors Service, Standard & Poor's Corporation and Fitch IBCA, Inc.
represent the respective rating agency's opinions of the credit quality of the
municipal securities they undertake to rate. However, their ratings are general
opinions and are not guarantees of quality. Municipal securities that have the
same maturity, coupon and rating may have different yields, while other
municipal securities that have the same maturity and coupon but different
ratings may have the same yield.

Lower grade securities may have a higher yield than securities rated in
the higher rating categories. In addition to having a greater risk of default
than higher-grade, securities, there may be less of a market for these
securities. As a result they may be harder to sell at an acceptable price. The
additional risks mean that the Fund may not receive the anticipated level of
income from these securities, and the Fund's net asset value may be affected by
declines in the value of lower-grade securities. However, because the added risk
of lower quality securities might not be consistent with the Fund's policy of
preservation of capital, the Fund limits its investments in lower quality
securities.

Subsequent to its purchase by the Fund, a municipal security may cease to
be rated or its rating may be reduced below the minimum required for purchase by
the Fund. Neither event requires the Fund to sell the security, but the Manager
will consider such events in determining whether the Fund should continue to
hold the security. To the extent that ratings given by Moody's, Standard &
Poor's, or Fitch change as a result of changes in those rating organizations or
their rating systems, the Fund will attempt to use comparable ratings as
standards for investments in accordance with the Fund's investment policies.

The Fund may buy municipal securities that are "pre-refunded." The
issuer's obligation to repay the principal value of the security is generally
collateralized with U.S. government securities placed in an escrow account. This
causes the pre-refunded security to have essentially the same risks of default
as a AAA-rated security.
A list of the rating categories of Moody's, S&P and Fitch for municipal
securities is contained in Appendix A to this Statement of Additional
Information. Because the Fund may purchase securities that are unrated by
nationally recognized rating organizations, the Manager will make its own
assessment of the credit quality of unrated issues the Fund buys. The Manager
will use criteria similar to those used by the rating agencies, and assigning a
rating category to a security that is comparable to what the Manager believes a
rating agency would assign to that security. However, the Manager's rating does
not constitute a guarantee of the quality of a particular issue.

Special Risks of Investing Primarily in Pennsylvania Municipal Securities.
Because the Fund focuses its investments primarily on Pennsylvania municipal
securities, the value of its portfolio investments will be highly sensitive to
events affecting the fiscal stability of the Commonwealth of Pennsylvania and
its municipalities, authorities and other instrumentalities that issue
securities. Many different social, environmental and economic factors may affect
the financial condition of Pennsylvania and its political subdivisions. From
time to time Pennsylvania and certain of its political subdivisions have
encountered financial difficulties that have adversely affected their respective
credit standings. Other factors that may negatively effect economic conditions
in Pennsylvania include adverse changes in employment rates, federal revenue
sharing or laws with respect to tax-exempt financing.

It is not possible to predict the future impact of the legislation and
economic considerations described below on the long-term ability of the
Commonwealth of Pennsylvania or Pennsylvania municipal issuers to pay interest
or repay principal on their obligations. The information below about these
conditions is only a brief summary, based upon information the Fund has drawn
from sources that it believes are reliable, including official statements
relating to securities offerings of Pennsylvania issuers.

|_| The Effect of General Economic Conditions in the State. The
Commonwealth of Pennsylvania is one of the most populous states, ranking fifth
behind California, New York, Texas and Florida. Pennsylvania is an established
yet growing state with a diversified economy. It is the headquarters for many
major corporations. Pennsylvania had historically been identified as a heavy
industry state. That reputation has changed over the last 30 years as the coal,
steel and railroad industries declined and the Commonwealth's business
environment readjusted to reflect a more diversified industrial base. This
economic readjustment was a direct result of a long-term shift in jobs,
investment and workers away from the northeast part of the nation. Currently,
the major sources of growth in Pennsylvania are in the service sector, including
trade, medical and the health services, education and financial institutions.
Pennsylvania's 5.9 million-person work force ranks as the sixth largest labor
pool in the nation.

The Commonwealth uses the fund method of accounting. The General Fund, the
Commonwealth's largest fund, receives all tax revenues, non-tax revenues and
federal grants and entitlements that are not specified by law to be deposited
elsewhere. The majority of the Commonwealth's operating and administrative
expenses are payable from the General Fund. Debt service and all bonded
indebtedness of the Commonwealth, except that issued for highway purposes or for
the benefit of other special revenue funds, is payable from the General Fund.

The period from fiscal year 1993 through fiscal year 1997 was a time of
steady, modest economic growth and low rates of inflation. These economic
conditions, together with tax reductions in the several years following the tax
rate increases and tax base expansions enacted in fiscal year 1991 for the
General Fund, produced tax revenue gains averaging 4.1% per year during the
period. Total revenues during this same period increased at a 4.7% average rate.
Expenditures and other uses during the fiscal years 1993 through fiscal 1997
period rose at a 3.8% rate, led by an average 13.8% annual increase in costs for
programs for the protection of persons and property. The fund balance at June
30, 1997 totaled $1,364.9 million, a $729.7 million increase over the $635.2
million balance at June 30, 1996.

Operations during the 1998 fiscal year increased the unappropriated
balance of Commonwealth revenues during that period by $86.4 million to $488.7
million at June 30, 1998 (prior to reserves for transfer to the Tax
Stabilization Reserve Fund). Higher than estimated revenues, offset in part by
increased reserves for tax refunds, and slightly lower expenditures than
budgeted were responsible for the increase. Commonwealth revenues (prior to tax
refunds) during the fiscal year totaled $18,123.2 million, $676.1 million (3.9%)
above the estimate made at the time the budget was enacted. Expenditures from
all fiscal year 1998 appropriations of Commonwealth revenues totaled $17,229.8
million (excluding pooled financing expenditures and net of current year
lapses). This amount represents an increase of 4.5% over fiscal year 1997
appropriation expenditures.

The budget for fiscal year 1999 was enacted in April 1998 at which time
the official revenue estimate for the 1999 fiscal year was established at
$18,456.6 million. Only Commonwealth funds are included in the official revenue
estimate. The official revenue estimate is based on an economic forecast for
national gross domestic product, on a year-over-year basis, to slow from an
estimated annualized 3.9% rate in the fourth quarter of 1997 to a projected 1.8%
annualized growth rate by the second quarter of 1999. The forecast of slowing
economic activity is based on the expectation that consumers will reduce their
pace of spending, particularly on motor vehicles, housing and other durable
goods. Business is also expected to trim its spending on fixed investments.
Foreign demand for domestic goods is expected to decline in reaction to economic
difficulties in Asia and Latin America, while an economic recovery in Europe is
expected to proceed slowly. The underlying growth rate, excluding any effect of
scheduled or proposed tax changes, for the General Fund fiscal 1999 official
revenue estimate is 3.0% over actual fiscal year 1998 revenues. When adjusted to
include the estimated effect of enacted tax changes, fiscal year 1999
Commonwealth revenues are projected to increase by 1.66% over actual
Commonwealth revenues for fiscal year 1998. Tax reductions anticipated to be
included in the enacted 1999 fiscal year budget totaled an estimated $241.0
million for fiscal year 1999.

The Commonwealth's government funds receive over 57% of their revenues
from taxes levied by the Commonwealth. Interest earnings, licenses and fees,
lottery tickets, liquor store profits, miscellaneous revenues, augmentations and
federal government grants supply the balance of the receipts to these funds. The
major sources for the General Fund of the Commonwealth are the sales tax, the
personal income tax and the corporate net income tax.

The current constitutional provisions relating to Commonwealth debt permit
the issuance of the following types of debt: (i) debt to suppress insurrection
or rehabilitate areas affected by disaster, (ii) electorate approved debt, (iii)
debt for capital projects subject to an aggregate debt limit of 1.75 times the
annual average tax revenue of the preceding five fiscal years, and (iv) tax
anticipation notes payable in the fiscal year of issuance. All debt except tax
anticipation notes must be amortized in substantial and regular amounts.
Outstanding general obligation debt totaled $4,724.5 million at June 30, 1998, a
decrease of $70.6 million from June 30, 1997.

Other state-related obligations include "moral obligations." Moral
obligation indebtedness may be issued by the Pennsylvania housing financing
agency, a state-created agency which provides financing for housing for lower
and moderate income families, and the Hospitals and Higher Education Facilities
Authority of Philadelphia, a municipal authority organized by the City of
Philadelphia to, among other things, acquire and prepare various sites for use
as intermediate care facilities for the mentally retarded.

The Commonwealth, through several of its departments and agencies, has
entered into various agreements to lease, as lessee, certain real property and
equipment, and to make lease payments for the use of such property and
equipment. Some of these leases and their respective lease payments are, with
the Commonwealth's approval, pledged as security for debt obligations issued by
certain public authorities or other entities within the state.

In addition, certain Commonwealth-created organizations had statutory
authorization for the issuance of debt for which Commonwealth appropriations to
pay debt service thereon are not required. The debt of these agencies is funded
by the assets of, or revenues derived from, the various projects financed and is
not a statutory or moral obligation of the Commonwealth. Some of these agencies,
however, are indirectly dependent on Commonwealth operating appropriations. The
Commonwealth also maintains pension plans covering state employees, public
school employees and employees of certain state-related organizations.

Pennsylvania's annual average unemployment rate was below the national
average from 1986 until 1990. Slower economic growth caused the unemployment
rate to rise in 1991 and 1992. However, the resumption of faster economic growth
resulted in a decrease in the Commonwealth's unemployment rate in 1993. In 1994
and 1995, Pennsylvania's annual average unemployment rate was below the middle
Atlantic region's average, but slightly higher than that of the United States.
In June, 1998, the Pennsylvania unemployment rate was slightly below that of the
United States. For 1997, per capita income in Pennsylvania was slightly above
the per capita income in the United States.

As of August 1, 1998, Pennsylvania general obligation bonds were rated AA-
by Standard & Poor's Corporation, Aa3 by Moody's Investors Service and AA by
Fitch IBCA, Inc. Those ratings are subject to change.

|_| Local Tax Considerations. Pennsylvania municipalities and school
districts are, with certain limitations, authorized to impose a variety of
taxes. The real estate tax is the only tax authorized by law to be levied by all
classes of local government in the state. Thus, property owners pay real estate
taxes to three independent authorities - the county, the municipality and the
school district. It is the leading local revenue producer in Pennsylvania.

The Local Tax Enabling Act, applicable to almost all political
subdivisions in Pennsylvania, gives local governments (other than counties) and
school districts in Pennsylvania a broad range of non-real estate tax sources.
The taxes commonly in use include the earned income or wage tax, per capita
taxes, occupation taxes, occupational privilege taxes, real estate transfer
taxes, amusement and admission taxes and business gross receipts taxes (although
the authority of political subdivisions to impose new business gross receipts
taxes is limited). Counties are also permitted to impose intangible personal
property taxes (although the constitutional validity of such taxes is presently
the subject of litigation and no counties presently impose such taxes).

In addition, the City and School District of Philadelphia have separate
taxing authority to impose a variety of business taxes, wage taxes, income and
other various taxes.

There is various litigation pending against the Commonwealth, its officers
and employees. An adverse decision in one or more of these cases could
materially affect the Commonwealth's governmental operations.

Other Investment Techniques and Strategies. In seeking its objective, the Fund
may from time to time employ the types of investment strategies and investments
described below.

|X| Floating Rate and Variable Rate Obligations. Variable rate demand
obligations have a demand feature that allows the Fund to tender the obligation
to the issuer or a third party to its maturity. The tender may be at par value
plus accrued interest, according to the terms of the obligation.

The interest rate on a floating rate demand note is based on a stated
prevailing market rate, such as a bank's prime rate, the 91-day U.S. Treasury
Bill rate, or some other standard, and is adjusted automatically each time such
rate is adjusted. The interest rate on a variable rate demand note is also based
on a stated prevailing market rate but is adjusted automatically at specified
intervals of not less than one year. Generally, the changes in the interest rate
on such securities reduce the fluctuation in their market value. As interest
rates decrease or increase, the potential for capital appreciation or
depreciation is less than that for fixed-rate obligations of the same maturity.

The Manager may determine that an unrated floating rate or variable rate
demand obligation meets the Fund's quality standards by reason of being backed
by a letter of credit or guarantee issued by a bank that meets those quality
standards.

Floating rate and variable rate demand notes that have a stated maturity
in excess of one year may have features that permit the holder to recover the
principal amount of the underlying security at specified intervals not exceeding
one year and upon no more than 30 days' notice. The issuer of that type of note
normally has a corresponding right in its discretion, after a given period, to
prepay the outstanding principal amount of the note plus accrued interest.
Generally the issuer must provide a specified number of days' notice to the
holder. Floating rate or variable rate obligations that do not provide for the
recovery of principal and interest within seven days are subject to the Fund's
limitations on investments in illiquid securities.

|X| Inverse Floaters and Other Derivative Investments. Inverse floaters
may offer relatively high current income, reflecting the spread between
short-term and long-term tax exempt interest rates. As long as the municipal
yield curve remains relatively steep and short term rates remain relatively low,
owners of inverse floaters will have the opportunity to earn interest at
above-market rates because they receive interest at the higher long-term rates
but have paid for bonds with lower short-term rates. If the yield curve flattens
and shifts upward, an inverse floater will lose value more quickly than a
conventional long-term bond. The Fund will invest in inverse floaters to seek
higher tax-exempt yields than are available from fixed-rate bonds that have
comparable maturities and credit ratings. In some cases, the holder of an
inverse floater may have an option to convert the floater to a fixed-rate bond,
pursuant to a "rate-lock option."

Some inverse floaters have a feature known as an interest rate "cap" as
part of the terms of the investment. Investing in inverse floaters that have
interest rate caps might be part of a portfolio strategy to try to maintain a
high current yield for the Fund when the Fund has invested in inverse floaters
that expose the Fund to the risk of short-term interest rate fluctuations.
"Embedded" caps can be used to hedge a portion of the Fund's exposure to rising
interest rates. When interest rates exceed a pre-determined rate, the cap
generates additional cash flows that offset the decline in interest rates on the
inverse floater, and the hedge is successful. However, the Fund bears the risk
that if interest rates do not rise above the pre-determined rate, the cap (which
is purchased for additional cost) will not provide additional cash flows and
will expire worthless.

Inverse floaters are a form of derivative investment. Certain derivatives,
such as options, futures, indexed securities and entering into swap agreements,
can be used to increase or decrease the Fund's exposure to changing security
prices, interest rates or other factors that affect the value of securities.
However, these techniques could result in losses to the Fund, if the Manager
judges market conditions incorrectly or employs a strategy that does not
correlate well with the Fund's other investments. These techniques can cause
losses if the counterparty does not perform its promises. An additional risk of
investing in municipal securities that are derivative investments is that their
market value could be expected to vary to a much greater extent than the market
value of municipal securities that are not derivative investments but have
similar credit quality, redemption provisions and maturities.

|X| When-Issued and Delayed Delivery Transactions. The Fund can purchase
securities on a "when-issued" basis, and may purchase or sell such securities on
a "delayed delivery" basis. "When-issued" or "delayed delivery" refers to
securities whose terms and indenture are available and for which a market
exists, but which are not available for immediate delivery.

When such transactions are negotiated the price (which is generally
expressed in yield terms) is fixed at the time the commitment is made. Delivery
and payment for the securities take place at a later date. Normally the
settlement date is within six months of the purchase of municipal bonds and
notes. However, the Fund may, from time to time, purchase municipal securities
having a settlement date more than six months and possibly as long as two years
or more after the trade date. The securities are subject to change in value from
market fluctuation during the settlement period. The value at delivery may be
less than the purchase price. For example, changes in interest rates in a
direction other than that expected by the Manager before settlement will affect
the value of such securities and may cause loss to the Fund.

The Fund will engage in when-issued transactions in order to secure what
is considered to be an advantageous price and yield at the time of entering into
the obligation. When the Fund engages in when-issued or delayed delivery
transactions, it relies on the buyer or seller, as the case may be, to complete
the transaction. Their failure to do so may cause the Fund to lose the
opportunity to obtain the security at a price and yield it considers
advantageous.

When the Fund engages in when-issued and delayed delivery transactions, it
does so for the purpose of acquiring or selling securities consistent with its
investment objective and policies for its portfolio or for delivery pursuant to
options contracts it has entered into, and not for the purposes of investment
leverage. Although the Fund will enter into when-issued or delayed-delivery
purchase transactions to acquire securities, the Fund may dispose of a
commitment prior to settlement. If the Fund chooses to dispose of the right to
acquire a when-issued security prior to its acquisition or to dispose of its
right to deliver or receive against a forward commitment, it may incur a gain or
loss.
At the time the Fund makes a commitment to purchase or sell a security on
a when-issued or forward commitment basis, it records the transaction on its
books and reflects the value of the security purchased. In a sale transaction,
it records the proceeds to be received, in determining its net asset value. The
Fund will identify to its Custodian cash, U.S. Government securities or other
high grade debt obligations at least equal to the value of purchase commitments
until the Fund pays for the investment.

When-issued transactions and forward commitments can be used by the Fund
as a defensive technique to hedge against anticipated changes in interest rates
and prices. For instance, in periods of rising interest rates and falling
prices, the Fund might sell securities in its portfolio on a forward commitment
basis to attempt to limit its exposure to anticipated falling prices. In periods
of falling interest rates and rising prices, the Fund might sell portfolio
securities and purchase the same or similar securities on a when-issued or
forward commitment basis, to obtain the benefit of currently higher cash yields.

|X| Zero-Coupon Securities. The Fund may buy zero-coupon and delayed
interest municipal securities. Zero-coupon securities do not make periodic
interest payments and are sold at a deep discount from their face value. The
buyer recognizes a rate of return determined by the gradual appreciation of the
security, which is redeemed at face value on a specified maturity date. This
discount depends on the time remaining until maturity, as well as prevailing
interest rates, the liquidity of the security and the credit quality of the
issuer. In the absence of threats to the issuer's credit quality, the discount
typically decreases as the maturity date approaches. Some zero-coupon securities
are convertible, in that they are zero-coupon securities until a predetermined
date, at which time they convert to a security with a specified coupon rate.

Because zero-coupon securities pay no interest and compound semi-annually
at the rate fixed at the time of their issuance, their value is generally more
volatile than the value of other debt securities. Their value may fall more
dramatically than the value of interest-bearing securities when interest rates
rise. When prevailing interest rates fall, zero-coupon securities tend to rise
more rapidly in value because they have a fixed rate of return.

The Fund's investment in zero-coupon securities may cause the Fund to
recognize income and make distributions to shareholders before it receives any
cash payments on the zero-coupon investment. To generate cash to satisfy those
distribution requirements, the Fund may have to sell portfolio securities that
it otherwise might have continued to hold or to use cash flows from other
sources such as the sale of Fund shares.

|X| Puts and Standby Commitments. When the Fund buys a municipal security
subject to a standby commitment to repurchase the security, the Fund is entitled
to same-day settlement from the purchaser. The Fund receives an exercise price
equal to the amortized cost of the underlying security plus any accrued interest
at the time of exercise. A put purchased in conjunction with a municipal
security enables the Fund to sell the underlying security within a specified
period of time at a fixed exercise price.

The Fund might purchase a standby commitment or put separately in cash or
it might acquire the security subject to the standby commitment or put (at a
price that reflects that additional feature). The Fund will enter into these
transactions only with banks and securities dealers that, in the Manager's
opinion, present minimal credit risks. The Fund's ability to exercise a put or
standby commitment will depend on the ability of the bank or dealer to pay for
the securities if the put or standby commitment is exercised. If the bank or
dealer should default on its obligation, the Fund might not be able to recover
all or a portion of any loss sustained from having to sell the security
elsewhere.

Puts and standby commitments are not transferable by the Fund. They
terminate if the Fund sells the underlying security to a third party. The Fund
intends to enter into these arrangements to facilitate portfolio liquidity,
although such arrangements might enable the Fund to sell a security at a
pre-arranged price that may be higher than the prevailing market price at the
time the put or standby commitment is exercised. However, the Fund might refrain
from exercising a put or standby commitment if the exercise price is
significantly higher than the prevailing market price, to avoid imposing a loss
on the seller that could jeopardize the Fund's business relationships with the
seller.

A put or standby commitment increases the cost of the security and reduces
the yield otherwise available from the security. Any consideration paid by the
Fund for the put or standby commitment will be reflected on the Fund's books as
unrealized depreciation while the put or standby commitment is held, and a
realized gain or loss when the put or commitment is exercised or expires.
Interest income received by the Fund from municipal securities subject to puts
or stand-by commitments may not qualify as tax exempt in its hands if the terms
of the put or stand-by commitment cause the Fund not to be treated as the tax
owner of the underlying municipal securities.

|X| Repurchase Agreements. The Fund may acquire securities subject to
repurchase agreements. It may do so for liquidity purposes to meet anticipated
redemptions of Fund shares, or pending the investment of the proceeds from sales
of Fund shares, or pending the settlement of portfolio securities. In a
repurchase transaction, the Fund acquires a security from, and simultaneously
resells it to an approved vendor for delivery on an agreed upon future date. The
resale price exceeds the purchase price by an amount that reflects an
agreed-upon interest rate effective for the period during which the repurchase
agreement is in effect. Approved vendors include U.S. commercial banks, U.S.
branches of foreign banks or broker-dealers that have been designated a primary
dealer in government securities, which meet the credit requirements set by the
Fund's Board of Trustees from time to time.

The majority of these transactions run from day to day. Delivery pursuant
to resale typically will occur within one to five days of the purchase.
Repurchase agreements having a maturity beyond seven days are subject to the
Fund's limits on holding illiquid investments. There is no limit on the amount
of the Fund's net assets that may be subject to repurchase agreements of seven
days or less.

Repurchase agreements, considered "loans" under the Investment Company
Act, are collateralized by the underlying security. The Fund's repurchase
agreements require that at all times while the repurchase agreement is in
effect, the collateral's value must equal or exceed the repurchase price to
fully collateralize the repayment obligation. Additionally, the Manager will
impose creditworthiness requirements to confirm that the vendor is financially
sound and will continuously monitor the collateral's value. However, if the
vendor fails to pay the resale price on the delivery date, the Fund may incur
costs in disposing of the collateral and may experience losses if there is any
delay in its ability to do so.

|X| Illiquid Securities. The Fund has percentage limitations that apply to
purchases of illiquid securities, as stated in the Prospectus. As a matter of
fundamental policy, the Fund cannot purchase any securities that are subject to
restrictions on resale.

|X| Loans of Portfolio Securities. To attempt to raise income or raise
cash for liquidity purposes, the Fund may lend its portfolio securities to
brokers, dealers and other financial institutions. These loans are limited to
not more than 25% of the value of the Fund's total assets. There are risks in
connection with securities lending. The Fund might experience a delay in
receiving additional collateral to secure a loan, or a delay in recovery of the
loaned securities. The Fund presently does not intend to engage in loans of
securities that will exceed 5% of the value of the Fund's total assets in the
coming year. Income from securities loans does not constitute exempt-interest
income for the purpose of paying tax-exempt dividends.

The Fund must receive collateral for a loan. Under current applicable
regulatory requirements (which are subject to change), on each business day the
loan collateral must be at least equal to the value of the loaned securities. It
must consist of cash, bank letters of credit, securities of the U.S. government
or its agencies or instrumentalities, or other cash equivalents in which the
Fund is permitted to invest. To be acceptable as collateral, letters of credit
must obligate a bank to pay amounts demanded by the Fund if the demand meets the
terms of the letter. The terms of the letter of credit and the issuing bank both
must be satisfactory to the Fund.

When it lends securities, the Fund receives amounts equal to the dividends
or interest on the loaned securities, It also receives one or more of (a)
negotiated loan fees, (b) interest on securities used as collateral, and (c)
interest on short-term debt securities purchased with the loan collateral.
Either type of interest may be shared with the borrower. The Fund may pay
reasonable finder's, administrative or other fees in connection with these
loans. The terms of the Fund's loans must meet applicable tests under the
Internal Revenue Code and must permit the Fund to reacquire loaned securities on
five days' notice or in time to vote on any important matter.

|X| Hedging. The Fund may use hedging to attempt to protect against
declines in the market value of its portfolio, to permit the Fund to retain
unrealized gains in the value of portfolio securities that have appreciated, or
to facilitate selling securities for investment reasons. To do so the Fund may:
|_| sell interest rate futures or municipal bond index futures, |_| buy
puts on such futures or securities, or |_| write covered calls on
securities, interest rate futures or municipal bond index futures. Covered
calls may also be written on debt securities to attempt to increase the
Fund's income, but that income would not be tax-exempt. Therefore it is
unlikely that the Fund would write covered calls for that purpose.

The Fund may also use hedging to establish a position in the debt
securities market as a temporary substitute for purchasing individual debt
securities. In that case the Fund will normally seek to purchase the securities,
and then terminate that hedging position. For this type of hedging, the Fund
may:
|_| buy interest rate futures or municipal bond index futures, or |_| buy
calls on such futures or on securities.

The Fund is not obligated to use hedging instruments, even though it is
permitted to use them in the Manager's discretion, as described below. The
Fund's strategy of hedging with futures and options on futures will be
incidental to the Fund's investment activities in the underlying cash market.
The particular hedging instruments the Fund can use are described below. The
Fund may employ new hedging instruments and strategies when they are developed,
if those investment methods are consistent with the Fund's investment objective
and are permissible under applicable regulations governing the Fund.

|_| Futures. The Fund may buy and sell futures contracts relating to debt
securities (these are called "interest rate futures") and municipal bond indices
(these are referred to as "municipal bond index futures").

An interest rate future obligates the seller to deliver (and the purchaser
to take) cash or a specific type of debt security to settle the futures
transaction. Either party could also enter into an offsetting contract to close
out the futures position.

A "municipal bond index" assigns relative values to the municipal bonds in
the index, and is used as the basis for trading long-term municipal bond futures
contracts. Municipal bond index futures are similar to interest rate futures
except that settlement is made only in cash. The obligation under the contract
may also be satisfied by entering into an offsetting contract. The strategies
which the Fund employs in using municipal bond index futures are similar to
those with regard to interest rate futures.

Upon entering into a futures transaction, the Fund will be required to
deposit an initial margin payment in cash or U.S. government securities with the
futures commission merchant (the "futures broker"). Initial margin payments will
be deposited with the Fund's Custodian in an account registered in the futures
broker's name. However, the futures broker can gain access to that account only
under certain specified conditions. As the future is marked to market (that is,
its value on the Fund's books is changed) to reflect changes in its market
value, subsequent margin payments, called variation margin, will be paid to or
by the futures broker daily.

At any time prior to the expiration of the Future, the Fund may elect to
close out its position by taking an opposite position at which time a final
determination of variation margin is made and additional cash is required to be
paid by or released to the Fund. Any gain or loss is then realized by the Fund
on the Future for tax purposes. Although Interest Rate Futures by their terms
call for settlement by the delivery of debt securities, in most cases the
obligation is fulfilled without such delivery by entering into an offsetting
transaction. All futures transactions are effected through a clearing house
associated with the exchange on which the contracts are traded.

The Fund may concurrently buy and sell futures contracts in a strategy
anticipating that the future the Fund purchased will perform better than the
future the Fund sold. For example, the Fund might buy municipal bond futures and
concurrently sell U.S. Treasury Bond futures (a type of interest rate future).
The Fund would benefit if municipal bonds outperform U.S. Treasury Bonds on a
duration-adjusted basis.

Duration is a volatility measure that refers to the expected percentage
change in the value of a bond resulting from a change in general interest rates
(measured by each 1% change in the rates on U.S. Treasury securities). For
example, if a bond has an effective duration of three years, a 1% increase in
general interest rates would be expected to cause the value of the bond to
decline about 3%. There are risks that this type of futures strategy will not be
successful. U.S. Treasury bonds might perform better on a duration-adjusted
basis than municipal bonds, and the assumptions about duration that were used
might be incorrect (in this case, the duration of municipal bonds relative to
U.S. Treasury Bonds might have been greater than anticipated).

|_| Put and Call Options. The Fund may buy and sell certain kinds of put
options (puts) and call options (calls). These strategies are described below.

|_| Writing Covered Call Options. The Fund may write (that is, sell)
call options. The Fund's call writing is subject to a number of restrictions:
(1) After the Fund writes a call, not more than 25% of the Fund's total
assets may be subject to calls.
(2) Calls the Fund sells must be listed on a securities or commodities
exchange or quoted on NASDAQ, the automated quotation system of The
Nasdaq Stock Market, Inc. or traded in the over-the-counter market.
(3) Each call the Fund writes must be "covered" while it is outstanding.
That means the Fund must own the investment on which the call was
written.
(4) The Fund may write calls on futures contracts that it owns, but these
calls must be covered by securities or other liquid assets that the Fund
owns and segregates to enable it to satisfy its obligations if the call
is exercised.

When the Fund writes a call on a security, it receives cash (a premium).
The Fund agrees to sell the underlying investment to a purchaser of a
corresponding call on the same security during the call period at a fixed
exercise price regardless of market price changes during the call period. The
call period is usually not more than nine months. The exercise price may differ
from the market price of the underlying security. The Fund has retained the risk
of loss that the price of the underlying security may decline during the call
period. That risk may be offset to some extent by the premium the Fund receives.
If the value of the investment does not rise above the call price, it is likely
that the call will lapse without being exercised. In that case the Fund would
keep the cash premium and the investment.

The Fund's Custodian, or a securities depository acting for the Custodian,
will act as the Fund's escrow agent through the facilities of the Options
Clearing Corporation ("OCC"), as to the investments on which the Fund has
written calls traded on exchanges, or as to other acceptable escrow securities.
In that way, no margin will be required for such transactions. OCC will release
the securities on the expiration of the calls or upon the Fund's entering into a
closing purchase transaction.

When the Fund writes an over-the-counter ("OTC") option, it will enter
into an arrangement with a primary U.S. Government securities dealer which will
establish a formula price at which the Fund will have the absolute right to
repurchase that OTC option. The formula price would generally be based on a
multiple of the premium received for the option, plus the amount by which the
option is exercisable below the market price of the underlying security (that
is, the option is "in-the-money"). When the Fund writes an OTC option, it will
treat as illiquid (for purposes of its restriction on illiquid securities) the
mark-to-market value of any OTC option held by it, unless the option is subject
to a buy-back agreement by the executing broker. The Securities and Exchange
Commission is evaluating whether OTC options should be considered liquid
securities. The procedure described above could be affected by the outcome of
that evaluation.

To terminate its obligation on a call it has written, the Fund may
purchase a corresponding call in a "closing purchase transaction." The Fund will
then realize a profit or loss, depending upon whether the net of the amount of
the option transaction costs and the premium received on the call the Fund wrote
was more or less than the price of the call the Fund purchased to close out the
transaction. A profit may also be realized if the call lapses unexercised,
because the Fund retains the underlying investment and the premium received. Any
such profits are considered short-term capital gains for Federal tax purposes,
as are premiums on lapsed calls. When distributed by the Fund they are taxable
as ordinary income.

The Fund may also write calls on futures contracts without owning the
futures contract or securities deliverable under the contract. To do so, at the
time the call is written, the Fund must cover the call by segregating in escrow
an equivalent dollar value of liquid assets. The Fund will segregate additional
liquid assets if the value of the escrowed assets drops below 100% of the
current value of the future. Because of this escrow requirement, in no
circumstances would the Fund's receipt of an exercise notice as to that future
put the Fund in a "short" futures position.

When the Fund purchases a call (other than in a closing purchase
transaction), it pays a premium. For calls on securities that the Fund buys, it
has the right to buy the underlying investment from a seller of a corresponding
call on the same investment during the call period at a fixed exercise price.
The Fund benefits only if (1) the call is sold at a profit or (2) the call is
exercised when the market price of the underlying investment is above the sum of
the exercise price plus the transaction costs and premium paid for the call. If
the call is not either exercised or sold (whether or not at a profit), it will
become worthless at its expiration date. In that case the Fund will lose its
premium payment and the right to purchase the underlying investment.

Calls on municipal bond indices, interest rate futures and municipal bond
index futures are settled in cash rather than by delivering the underlying
investment. Gain or loss depends on changes in the securities included in the
index in question (and thus on price movements in the debt securities market
generally) rather than on changes in price of the individual futures contract.

The Fund may buy only those puts that relate to securities that the Fund
owns, broadly-based municipal bond indices, municipal bond index futures or
interest rate futures (whether or not the Fund owns the futures). The Fund may
not sell puts other than puts it has previously purchased.

When the Fund purchases a put, it pays a premium. The Fund then has the
right to sell the underlying investment to a seller of a corresponding put on
the same investment during the put period at a fixed exercise price. Puts on
municipal bond indices are settled in cash. Buying a put on a debt security,
interest rate future or municipal bond index future the Fund owns enables it to
protect itself during the put period against a decline in the value of the
underlying investment below the exercise price. If the market price of the
underlying investment is equal to or above the exercise price and as a result
the put is not exercised or resold, the put will become worthless at its
expiration date. In that case the Fund will lose its premium payment and the
right to sell the underlying investment. A put may be sold prior to expiration
(whether or not at a profit).

|_| Risks of Hedging with Options and Futures. The use of hedging
instruments requires special skills and knowledge of investment techniques that
are different than what is required for normal portfolio management. If the
Manager uses a hedging instrument at the wrong time or judges market conditions
incorrectly, hedging strategies may reduce the Fund's returns.

The Fund's option activities may affect its portfolio turnover rate and
brokerage commissions. The exercise of calls written by the Fund may cause the
Fund to sell related portfolio securities, thus increasing its turnover rate.
The exercise by the Fund of puts on securities will cause the sale of underlying
investments, increasing portfolio turnover. Although the decision whether to
exercise a put it holds is within the Fund's control, holding a put might cause
the Fund to sell the related investments for reasons that would not exist in the
absence of the put.

The Fund may pay a brokerage commission each time it buys a call or put,
sells a call, or buys or sells an underlying investment in connection with the
exercise of a call or put. Such commissions may be higher on a relative basis
than the commissions for direct purchases or sales of the underlying
investments. Premiums paid for options are small in relation to the market value
of the underlying investments. Consequently, put and call options offer large
amounts of leverage. The leverage offered by trading in options could result in
the Fund's net asset value being more sensitive to changes in the value of the
underlying investment.

If a covered call written by the Fund is exercised on an investment that
has increased in value, the Fund will be required to sell the investment at the
call price. It will not be able to realize any profit if the investment has
increased in value above the call price.

There is a risk in using short hedging by selling interest rate futures
and municipal bond index futures or purchasing puts on municipal bond indices or
futures to attempt to protect against declines in the value of the Fund's
securities. The risk is that the prices of such futures or the applicable index
will correlate imperfectly with the behavior of the cash (that is, market)
prices of the Fund's securities. It is possible for example, that while the Fund
has used hedging instruments in a short hedge, the market may advance and the
value of debt securities held in the Fund's portfolio may decline. If that
occurred, the Fund would lose money on the hedging instruments and also
experience a decline in value of its debt securities. However, while this could
occur over a brief period or to a very small degree, over time the value of a
diversified portfolio of debt securities will tend to move in the same direction
as the indices upon which the hedging instruments are based.

The risk of imperfect correlation increases as the composition of the
Fund's portfolio diverges from the securities included in the applicable index.
To compensate for the imperfect correlation of movements in the price of debt
securities being hedged and movements in the price of the hedging instruments,
the Fund may use hedging instruments in a greater dollar amount than the dollar
amount of debt securities being hedged. It might do so if the historical
volatility of the prices of the debt securities being hedged is greater than the
historical volatility of the applicable index.

The ordinary spreads between prices in the cash and futures markets are
subject to distortions due to differences in the natures of those markets. All
participants in the futures markets are subject to margin deposit and
maintenance requirements. Rather than meeting additional margin deposit
requirements, investors may close out futures contracts through offsetting
transactions which could distort the normal relationship between the cash and
futures markets. From the point of view of speculators, the deposit requirements
in the futures markets are less onerous than margin requirements in the
securities markets. Therefore, increased participation by speculators in the
futures markets may cause temporary price distortions.

The Fund may use hedging instruments to establish a position in the
municipal securities markets as a temporary substitute for the purchase of
individual securities (long hedging). It is possible that the market may
decline. If the Fund then concludes not to invest in such securities because of
concerns that there may be further market decline or for other reasons, the Fund
will realize a loss on the hedging instruments that is not offset by a reduction
in the purchase price of the securities.

An option position may be closed out only on a market that provides
secondary trading for options of the same series. There is no assurance that a
liquid secondary market will exist for a particular option. If the Fund could
not effect a closing purchase transaction due to a lack of a market, it would
have to hold the callable investment until the call lapsed or was exercised.

|_| Interest Rate Swap Transactions. In an interest rate swap, the Fund
and another party exchange their right to receive or their obligation to pay
interest on a security. For example, they may swap a right to receive floating
rate payments for fixed rate payments. The Fund enters into swaps only on
securities it owns. The Fund may not enter into swaps with respect to more than
25% of its total assets. Also, the Fund will segregate liquid assets (such as
cash or U.S. Government securities) to cover any amounts it could owe under
swaps that exceed the amounts it is entitled to receive, and it will adjust that
amount daily, as needed. Income from interest rate swaps may be taxable.

Swap agreements entail both interest rate risk and credit risk. There is a
risk that, based on movements of interest rates in the future, the payments made
by the Fund under a swap agreement will have been greater than those received by
it. Credit risk arises from the possibility that the counterparty will default.
If the counterparty to an interest rate swap defaults, the Fund's loss will
consist of the net amount of contractual interest payments that the Fund has not
yet received. The Manager will monitor the creditworthiness of counterparties to
the Fund's interest rate swap transactions on an ongoing basis.

The Fund will enter into swap transactions with appropriate counterparties
pursuant to master netting agreements. A master netting agreement provides that
all swaps done between the Fund and that counterparty under the master agreement
shall be regarded as parts of an integral agreement. If on any date amounts are
payable under one or more swap transactions, the net amount payable on that date
shall be paid. In addition, the master netting agreement may provide that if one
party defaults generally or on one swap, the counterparty may terminate the
swaps with that party. Under master netting agreements, if there is a default
resulting in a loss to one party, that party's damages are calculated by
reference to the average cost of a replacement swap with respect to each swap.
The gains and losses on all swaps are then netted, and the result is the
counterparty's gain or loss on termination. The termination of all swaps and the
netting of gains and losses on termination is generally referred to as
"aggregation."

|_| Regulatory Aspects of Hedging Instruments. When using futures and
options on futures, the Fund is required to operate within certain guidelines
and restrictions established by the Commodity Futures Trading Commission (the
"CFTC"). In particular, the Fund is exempted from registration with the CFTC as
a "commodity pool operator" if the Fund complies with the requirements of Rule
4.5 adopted by the CFTC. That Rule does not limit the percentage of the Fund's
assets that may be used for Futures margin and related options premiums for a
bona fide hedging position. However, under the Rule the Fund must limit its
aggregate initial futures margin and related options premiums to no more than 5%
of the Fund's net assets for hedging strategies that are not considered bona
fide hedging strategies under the Rule. Under the Rule, the Fund also must use
short futures and options on futures positions solely for bona fide hedging
purposes within the meaning and intent of the applicable provisions of the
Commodity Exchange Act.

Transactions in options by the Fund are subject to limitations established
by the option exchanges. The exchanges limit the maximum number of options that
may be written or held by a single investor or group of investors acting in
concert. Those limits apply regardless of whether the options were written or
purchased on the same or different exchanges, or are held in one or more
accounts or through one or more different exchanges or through one or more
brokers. Thus, the number of options that the Fund may write or hold may be
affected by options written or held by other entities, including other
investment companies having the same adviser as the Fund (or an adviser that is
an affiliate of the Fund's adviser). The exchanges also impose position limits
on futures transactions. An exchange may order the liquidation of positions
found to be in violation of those limits and may impose certain other sanctions.

Under the Investment Company Act, when the Fund purchases an interest rate
future or municipal bond index future, it must maintain cash or readily
marketable short-term debt instruments in an amount equal to the market value of
the investments underlying the future, less the margin deposit applicable to it.
The account must be a segregated account or accounts held by its custodian bank.

|X| Temporary Defensive Investments. The securities the Fund may invest
in for temporary defensive purposes include the following:
|_| short-term municipal securities;
|_| obligations issued or guaranteed by the U.S. Government or its
agencies or instrumentalities; |_| corporate debt securities rated
within the three highest grades by a nationally recognized rating
agency; |_| commercial paper rated "A-1" by S&P, or a comparable rating
by another nationally recognized rating agency; and |_| certificates of
deposit of domestic banks with assets of $1 billion or more.

|X| Taxable Investments. While the Fund can invest up to 20% of its total
assets in investments that generate income subject to income taxes, it does not
anticipate investing substantial amounts of its assets in taxable investments
under normal market conditions or as part of its normal trading strategies and
policies. To the extent it invests in taxable securities, the Fund would not be
able to meet its objective of providing tax exempt income to its shareholders.
Taxable investments include, for example, hedging instruments, repurchase
agreements, and the types of securities it would buy for temporary defensive
purposes.

Investment Restrictions

|X| What Are "Fundamental Policies?" Fundamental policies are those
policies that the Fund has adopted to govern its investments that can be changed
only by the vote of a "majority" of the Fund's outstanding voting securities.
Under the Investment Company Act, such a "majority" vote is defined as the vote
of the holders of the lesser of:
|_| 67% or more of the shares present or represented by proxy at a
shareholder meeting, if the holders of more than 50% of the outstanding
shares are present or represented by proxy, or |_| more than 50% of the
outstanding shares.

The Fund's investment objective is a fundamental policy. Other policies
described in the Prospectus or this Statement of Additional Information are
"fundamental" only if they are identified as such. The Fund's Board of Trustees
can change non-fundamental policies without shareholder approval. However,
significant changes to investment policies will be described in supplements or
updates to the Prospectus or this Statement of Additional Information, as
appropriate. The Fund's most significant investment policies are described in
the Prospectus.

|X| Does the Fund Have Additional Fundamental Policies? The following
investment restrictions are fundamental policies of the Fund:

|_| The Fund cannot invest in securities or other investments other than
municipal securities, the temporary investments described in its Prospectus,
repurchase agreements, covered calls, private activity municipal securities and
hedging instruments described in "About the Fund" in the Prospectus or this
Statement of Additional Information.

|_| The Fund cannot make loans. However, repurchase agreements and the
purchase of debt securities in accordance with the Fund's other investment
policies and restrictions are permitted. The Fund may also lend its portfolio
securities as described in "Loans of Portfolio Securities."

|_| The Fund cannot borrow money in excess of 10% of the value of its
total assets. It cannot buy any additional investments when borrowings exceed 5%
of its assets. The Fund may borrow only from banks as a temporary measure for
extraordinary or emergency purposes, and not for the purpose of leveraging its
investments.

|_| The Fund cannot pledge, mortgage or otherwise encumber, transfer or
assign its assets to secure a debt. However, the use of escrow or other
collateral arrangements in connection with hedging instruments is permitted.

|_| The Fund cannot concentrate its investments to the extent of 25% of
its total assets in any industry. However, there is no limitation as to the
Fund's investments in municipal securities in general or in Pennsylvania
municipal securities, or in obligations issued by the U.S. Government and its
agencies or instrumentalities.

|_| The Fund cannot invest in real estate. This restriction shall not
prevent the Fund from investing in municipal securities or other permitted
securities that are secured by real estate or interests in real estate.

|_| The Fund cannot purchase securities other than hedging instruments on
margin. However, the Fund may obtain short-term credits that may be necessary
for the clearance of purchases and sales of securities.

|_| The Fund cannot sell securities short.

|_| The Fund cannot underwrite securities or invest in securities that are
subject to restrictions on resale.

|_| The Fund cannot invest in or hold securities of any issuer if officers
and Trustees of the Fund or the Manager individually beneficially own more than
1/2 of 1% of the securities of that issuer and together own more than 5% of the
securities of that issuer.

|_| The Fund cannot invest in securities of any other investment company,
except in connection with a merger with another investment company.

|_| The Fund cannot buy or sell futures contracts other than interest rate
futures and municipal bond index futures.

Unless the Prospectus or Statement of Additional Information states that a
percentage restriction applies on an ongoing basis, it applies only at the time
the Fund makes an investment. In that case the Fund need not sell securities to
meet the percentage limits if the value of the investment increases in
proportion to the size of the Fund.

The Fund currently has an operating policy (which is not a fundamental
policy but will not be changed without the approval of a shareholder vote) that
prohibits the Fund from issuing senior securities. However, that policy does not
prohibit certain activities that are permitted by the Fund's other policies,
including borrowing money for emergency purposes as permitted by its other
investment policies and applicable regulations, entering into delayed-delivery
and when-issued arrangements for portfolio securities transactions, and entering
into contracts to buy or sell derivatives, hedging instruments, options, futures
and the related margin, collateral or escrow arrangements permitted under its
other investment policies.

Non-Diversification of the Fund's Investments. The Fund is a series of a trust
that is "non-diversified," as defined in the Investment Company Act. Funds that
are diversified have restrictions against investing too much of their assets in
the securities of any one "issuer." That means that the Fund can invest more of
its assets in the securities of a single issuer than a fund that is diversified.

Being non-diversified poses additional investment risks, because if the
Fund invests more of its assets in fewer issuers, the value of its shares is
subject to greater fluctuations from adverse conditions affecting any one of
those issuers. However, the Fund does limit its investments in the securities of
any one issuer to qualify for tax purposes as a "regulated investment company"
under the Internal Revenue Code. By qualifying, it does not have to pay federal
income taxes if more than 90% of its earnings are distributed to shareholders.
To qualify, the Fund must meet a number of conditions. First, not more than 25%
of the market value of the Fund's total assets may be invested in the securities
of a single issuer. Second, with respect to 50% of the market value of its total
assets, (1) no more than 5% of the market value of its total assets may be
invested in the securities of a single issuer, and (2) the Fund must not own
more than 10% of the outstanding voting securities of a single issuer.

The identification of the issuer of a municipal security depends on the
terms and conditions of the security. When the assets and revenues of an agency,
authority, instrumentality or other political subdivision are separate from
those of the government creating it and the security is backed only by the
assets and revenues of the subdivision, agency, authority or instrumentality,
the latter would be deemed to be the sole issuer. Similarly, if an industrial
development bond is backed only by the assets and revenues of the
non-governmental user, then that user would be deemed to be the sole issuer.
However, if in either case the creating government or some other entity
guarantees a security, the guarantee would be considered a separate security and
would be treated as an issue of such government or other entity.

Applying the Restriction Against Concentration. To implement its policy not to
concentrate its investments, the Fund has adopted the industry classifications
set forth in Appendix B to this Statement of Additional Information. Those
industry classifications are not a fundamental policy.

In implementing the Fund's policy not to concentrate its investments, the
Manager will consider a non-governmental user of facilities financed by
industrial development bonds as being in a particular industry. That is done
even though the bonds are municipal securities, as to which the Fund has no
concentration limitation. Although this application of the concentration
restriction is not a fundamental policy of the Fund, it will not be changed
without shareholder approval. The Manager has no present intention of investing
more than 25% of the Fund's total assets in securities paying interest from
revenues of similar type projects or in industrial development bonds. This is
not a fundamental policy and therefore could be changed without shareholder
approval. However, if that change were made, the Prospectus or this Statement of
Additional Information would be supplemented to reflect the change.

How the Fund Is Managed

Organization and History. The Fund was originally organized in 1989 as a
Massachusetts business trust having one series, the Fund. In 1993 it was
reorganized to be a multi-series business trust (now called Oppenheimer
Multi-State Municipal Trust) and the Fund became a separate series of that
Trust. The Trust is an open-end, non-diversified management investment company
with an unlimited number of authorized shares of beneficial interest. Each of
the three series of the Trust is a separate fund that issues its own shares, has
its own investment portfolio, and has its own assets and liabilities.

The Fund is governed by a Board of Trustees, which is responsible for
protecting the interests of shareholders under Massachusetts law. The Trustees
meet periodically throughout the year to oversee the Fund's activities, review
its performance, and review the actions of the Manager. Although the Fund will
not normally hold annual meetings of its shareholders, it may hold shareholder
meetings from time to time on important matters, and shareholders have the right
to call a meeting to remove a Trustee or to take other action described in the
Fund's Declaration of Trust.

o has its own dividends and distributions,
o pays certain expenses which may be different for the different
classes,
o may have a different net asset value,
o may have separate voting rights on matters in which the interests of one
class are different from the interests of another class, and
o votes as a class on matters that affect that class alone.

|_| Meetings of Shareholders. As a series of a Massachusetts business
trust, the Fund is not required to hold, and does not plan to hold, regular
annual meetings of shareholders. The Fund will hold meetings when required to do
so by the Investment Company Act or other applicable law. It will also do so
when a shareholder meeting is called by the Trustees or upon proper request of
the shareholders.

Shareholders have the right, upon the declaration in writing or vote of
two-thirds of the outstanding shares of the Fund, to remove a Trustee. The
Trustees will call a meeting of shareholders to vote on the removal of a Trustee
upon the written request of the record holders of 10% of its outstanding shares.
If the Trustees receive a request from at least 10 shareholders stating that
they wish to communicate with other shareholders to request a meeting to remove
a Trustee, the Trustees will then either make the Fund's shareholder list
available to the applicants or mail their communication to all other
shareholders at the applicants' expense. The shareholders making the request
must have been shareholders for at least six months and must hold shares of the
Fund valued at $25,000 or more or constituting at least 1% of the Fund's
outstanding shares, whichever is less. The Trustees may also take other action
as permitted by the Investment Company Act.

|_| Shareholder and Trustee Liability. The Fund's Declaration of Trust
contains an express disclaimer of shareholder or Trustee liability for the
Fund's obligations. It also provides for indemnification and reimbursement of
expenses out of the Fund's property for any shareholder held personally liable
for its obligations. The Declaration of Trust also states that upon request, the
Fund shall assume the defense of any claim made against a shareholder for any
act or obligation of the Fund and shall satisfy any judgment on that claim.
Massachusetts law permits a shareholder of a business trust (such as the trust
of which the Fund is a series) to be held personally liable as a "partner" under
certain circumstances. However, the risk that a Fund shareholder will incur
financial loss from being held liable as a "partner" of the Fund is limited to
the relatively remote circumstances in which the Fund would be unable to meet
its obligations.

The Fund's contractual arrangements state that any person doing business
with the Fund (and each shareholder of the Fund) agrees under its Declaration of
Trust to look solely to the assets of the Fund for satisfaction of any claim or
demand that may arise out of any dealings with the Fund. The contracts further
state that the Trustees shall have no personal liability to any such person, to
the extent permitted by law.

3 Committee position held during a portion of the period shown. 4 Includes $168
deferred under Deferred Compensation Plan described below.

|X| Retirement Plan for Trustees. The Fund has adopted a retirement plan
that provides for payments to retired Trustees. Payments are up to 80% of the
average compensation paid during a Trustee's five years of service in which the
highest compensation was received. A Trustee must serve as trustee for any of
the New York-based Oppenheimer funds for at least 15 years to be eligible for
the maximum payment. Each Trustee's retirement benefits will depend on the
amount of the Trustee's future compensation and length of service. Therefore the
amount of those benefits cannot be determined at this time, nor can we estimate
the number of years of credited service that will be used to determine those
benefits.

|X| Deferred Compensation Plan for Trustees. The Board of Trustees has
adopted a Deferred Compensation Plan for disinterested trustees that enables
them to elect to defer receipt of all or a portion of the annual fees they are
entitled to receive from the Fund. Under the plan, the compensation deferred by
a Trustee is periodically adjusted as though an equivalent amount had been
invested 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 materially affect the
Fund's assets, liabilities or net income per share. The plan will not obligate
the Fund to retain the services of any Trustee or to pay any particular level of
compensation to any Trustee. Pursuant to an Order issued by the Securities and
Exchange Commission, the Fund may invest in the funds selected by the Trustee
under the plan without shareholder approval for the limited purpose of
determining the value of the Trustee's deferred fee account.

|X| Major Shareholders. As of November 2, 1998, the only persons who owned
of record or who were known by the Fund to own beneficially 5% or more of the
Fund's outstanding Class A, Class B or Class C shares were:

James E. Beasley
c/o Beasley Casey & Erbstein
1125 Walnut Street
Philadelphia, PA 19107
363,918.832 Class A shares (approximately 6.38% of the Class A shares
then outstanding)

Merrill Lynch Pierce Fenner & Smith Inc. (which advised the Fund that such
shares were held beneficially for its customers) 4800 Deer Lake Drive
East, Floor 3, Jacksonville, Florida 32246 132,406.743 Class B shares
(approximately 7.17% of the Class B shares then outstanding) 147,250.525
Class C shares (approximately 32.25% of the Class C shares then
outstanding)

The Manager. The Manager is wholly-owned by Oppenheimer Acquisition Corp., a
holding company controlled by Massachusetts Mutual Life Insurance Company. The
Manager and the Fund have a Code of Ethics. It is designed to detect and prevent
improper personal trading by certain employees, including portfolio managers,
that would compete with or take advantage of the Fund's portfolio transactions.
Compliance with the Code of Ethics is carefully monitored and strictly enforced
by the Manager.

The portfolio manager of the Fund is principally responsible for the
day-to-day management of the Fund's investment portfolio. Other members of the
Manager's fixed-income portfolio department, particularly security analysts,
traders and other portfolio managers have broad experience with fixed-income
securities. They provide the Fund's portfolio manager with research and support
in managing the Fund's investments.

|X| The Investment Advisory Agreement. The Manager provides investment
advisory and management services to the Fund under an investment advisory
agreement between the Manager and the Fund. The Manager selects securities for
the Fund's portfolio and handles its day-to day business. That agreement
requires the Manager, at its expense, to provide the Fund with adequate office
space, facilities and equipment. It also requires the Manager to provide and
supervise the activities of all administrative and clerical personnel required
to provide effective corporate administration for the Fund. Those
responsibilities include the compilation and maintenance of records with respect
to the Fund's operations, the preparation and filing of specified reports, and
the composition of proxy materials and registration statements for continuous
public sale of shares of the Fund.

Expenses not expressly assumed by the Manager under the advisory agreement
are paid by the Fund. The investment advisory agreement lists examples of
expenses paid by the Fund. The major categories relate to interest, taxes, fees
to disinterested Trustees, legal and audit expenses, custodian and transfer
agent expenses, share issuance costs, certain printing and registration costs,
brokerage commissions, and non-recurring expenses, including litigation cost.
The management fees paid by the Fund to the Manager are calculated at the rates
described in the Prospectus, which are applied to the assets of the Fund as a
whole. The fees are allocated to each class of shares based upon the relative
proportion of the Fund's net assets represented by that class.

The investment advisory agreement contains no limitation of the Fund's
expenses by the Manager. The Manager has voluntarily agreed to waive receipt of
a portion of its annual management fee to the extent necessary to limit the
annual management fee to not more than 0.57% of average annual net assets of
each class of shares. The Manager may withdraw that waiver at any time. The
management fees paid by the Fund to the Manager during its last three fiscal
years are listed below. Also shown is the amount the management fee would have
been without the waiver. Under its voluntary expense waiver, the Manager
absorbed $8,996 of the Fund's expenses in the Fund's 1996 fiscal year, $33,555
in its 1997 fiscal year, and $53,282 in the Fund's 1998 fiscal year.

The investment advisory agreement contains an indemnity of the Manager. In
the absence of willful misfeasance, bad faith, gross negligence in the
performance of its duties, or reckless disregard for its obligations and duties
under the investment advisory agreement, the Manager is not liable for any loss
sustained by reason of any investment of the Fund assets made with due care and
in good faith. The agreement permits the Manager to act as investment adviser
for any other person, firm or corporation and to use the name "Oppenheimer" in
connection with other investment companies for which it may act as investment
adviser or general distributor. If the Manager shall no longer act as investment
adviser to the Fund, the Manager may withdraw the Fund's right to use the name
"Oppenheimer" as part of its name.

Brokerage Policies of the Fund

Brokerage Provisions of the Investment Advisory Agreement. One of the duties of
the Manager under the investment advisory agreement is to buy and sell portfolio
securities for the Fund. The investment advisory agreement allows the Manager to
use broker-dealers to effect the Fund's portfolio transactions. Under the
agreement, the Manager may employ those broker-dealers (including "affiliated"
brokers, as that term is defined in the Investment Company Act) that, in the
Manager's best judgment based on all relevant factors, will implement the Fund's
policy to obtain, at reasonable expense, the "best execution" of portfolio
transactions. "Best execution" refers to prompt and reliable execution at the
most favorable price obtainable. The Manager need not seek competitive
commission bidding. However, the Manager is expected to minimize the commissions
paid to the extent consistent with the interest and policies of the Fund as
established by its Board of Trustees.

Under the investment advisory agreement, the Manager may select brokers
that provide brokerage and/or research services for the Fund and/or the other
accounts over which the Manager or its affiliates have investment discretion.
The commissions paid to such brokers may be higher than another qualified broker
would charge, if the Manager makes a good faith determination that the
commission is fair and reasonable in relation to the services provided. Subject
to those other considerations, as a factor in selecting brokers for the Fund's
portfolio transactions, the Manager may also consider sales of shares of the
Fund and other investment companies managed by the Manager or its affiliates.

Brokerage Practices Followed by the Manager. The Manager allocates brokerage for
the Fund subject to the provisions of the investment advisory agreement and the
procedures and rules described above. Generally the Manager's portfolio traders
allocate brokerage upon recommendations from the Manager's portfolio managers.
In certain instances, portfolio managers may directly place trades and allocate
brokerage. In either case, the Manager's executive officers supervise the
allocation of brokerage.

Most securities purchases made by the Fund are in principal transactions
at net prices. The Fund usually deals directly with the selling or purchasing
principal or market maker without incurring charges for the services of a broker
on its behalf unless the Manager determines that a better price or execution may
be obtained by using the services of a broker. Therefore, the Fund does not
incur substantial brokerage costs. Portfolio securities purchased from
underwriters include a commission or concession paid by the issuer to the
underwriter in the price of the security. Portfolio securities purchased from
dealers include a spread between the bid and asked price.

The Fund seeks to obtain prompt execution of orders at the most favorable
net prices. In an option transaction, the Fund ordinarily uses the same broker
for the purchase or sale of the option and any transaction in the investment to
which the option relates. When possible, the Manager tries to combine concurrent
orders to purchase or sell the same security by more than one of the accounts
managed by the Manager or its affiliates. The transactions under those combined
orders are averaged as to price and allocated in accordance with the purchase or
sale orders actually placed for each account.

The investment advisory agreement permits the Manager to allocate
brokerage for research services. The research services provided by a particular
broker may be useful only to one or more of the advisory accounts of the Manager
and its affiliates. Investment research received by the Manager for the
commissions paid by those other accounts may be useful both to the Fund and one
or more of the Manager's other accounts. Investment research services may be
supplied to the Manager by a third party at the instance of a broker through
which trades are placed. Investment research services include information and
analyses on particular companies and industries as well as market or economic
trends and portfolio strategy, market quotations for portfolio evaluations,
information systems, computer hardware and similar products and services. If a
research service also assists the Manager in a non-research capacity (such as
bookkeeping or other administrative functions), then only the percentage or
component that provides assistance to the Manager in the investment
decision-making process may be paid in commission dollars.

The Board of Trustees has permitted the Manager to use concessions on
fixed-price offerings to obtain research, in the same manner as is permitted for
agency transactions. The Board has also permitted the Manager to use stated
commissions on secondary fixed-income agency trades to obtain research if the
broker represents to the Manager that: (i) the trade is not from or for the
broker's own inventory, (ii) the trade was executed by the broker on an agency
basis at the stated commission, and (iii) the trade is not a riskless principal
transaction.

The research services provided by brokers broaden the scope and supplement
the research activities of the Manager. That research provides additional views
and comparisons for consideration and helps the Manager to obtain market
information for the valuation of securities that are either held in the Fund's
portfolio or are being considered for purchase. The Manager provides information
to the Board of the Fund about the commissions paid to brokers furnishing
research services, together with the Manager's representation that the amount of
such commissions was reasonably related to the value or benefit of such
services.

Other funds advised by the Manager have investment objectives and policies
similar to those of the Fund. Those other funds may purchase or sell the same
securities as the Fund at the same time as the Fund, which could affect the
supply and price of the securities. If two or more of funds advised by the
Manager purchase the same security on the same day from the same dealer, the
Manager may average the price of the transactions and allocate the average among
the funds.

Distribution and Service Plans

The Distributor. Under its General Distributor's Agreement with the Fund, the
Distributor acts as the Fund's principal underwriter in the continuous public
offering of the Fund's Class A, Class B and Class C shares. The Distributor is
not obligated to sell a specific number of shares. Expenses normally
attributable to sales are borne by the Distributor. They exclude payments under
the Distribution and Service Plans but include advertising and the cost of
printing and mailing prospectuses (other than those furnished to existing
shareholders).

The compensation paid to (or retained by) the Distributor from the sale of
shares or on the redemption of shares is discussed in the table below:

For additional information about distribution of the Fund's shares,
including fees and expenses, please refer to "Distribution and Service Plans."

Distribution and Service Plans. The Fund has adopted a Service Plan for its
Class A shares and Distribution and Service Plans for its Class B and Class C
shares under Rule 12b-1 of the Investment Company Act. Under those plans, the
Fund makes payments to the Distributor in connection with the distribution
and/or servicing of the shares of the particular class.

Each plan has been approved by a vote of the Board of Trustees of the
Fund, including a majority of the Independent Trustees, cast in person at a
meeting called for the purpose of voting on that plan. Each plan has also been
approved by a vote of the holders of a "majority" (as defined in the Investment
Company Act) of the shares of each class. The Manager cast the vote to approve
the Class C plan as the sole initial holder of Class C shares.

Under the plans the Manager and the Distributor, in their sole discretion,
from time to time may use their own resources to make payments to brokers,
dealers or other financial institutions for distribution and administrative
services they perform at no cost to the Fund. The Manager may use profits from
the advisory fee it receives from the Fund. The Distributor and the Manager may,
in their sole discretion, increase or decrease the amount of payments they make
to plan recipients from their own resources.

Unless a plan is terminated as described below, the plan continues in
effect from year to year, but only if the Fund's Board of Trustees and its
Independent Trustees specifically vote annually to approve its continuance.
Approval must be by a vote cast in person at a meeting called for the purpose of
voting on continuing the plan. A plan may be terminated at any time by the vote
of a majority of the Independent Trustees or by the vote of the holders of a
"majority" (as defined in the Investment Company Act) of the outstanding shares
of that class.

The Board and the Independent Trustees must approve all material
amendments to a plan. An amendment to increase materially the amount of payments
to be made under the plan must be approved by shareholders of the class affected
by the amendment. Because Class B shares automatically convert into Class A
shares after six years, the Fund must obtain the approval of both Class A and
Class B shareholders for an amendment to the Class A plan that would materially
increase the amount to be paid under that plan. That approval must be by a
"majority" (as defined in the Investment Company Act) of the shares of each
class, voting separately by Class.

While the plans are in effect, the Treasurer of the Fund shall provide
separate written reports on the plans to the Fund's Board of Trustees at least
quarterly for its review. The reports shall detail the amount of all payments
made under a plan, the purpose for which the payments were made and the identity
of each recipient of a payment. The report on the Class B and Class C plans
shall also include the Distributor's distribution costs for the quarter, and any
costs for previous fiscal periods that have been carried forward. Those reports
are subject to the review and approval of the Independent Trustees in the
exercise of their fiduciary duty.

Each plan states that while it is in effect, the selection or replacement
and nomination of those Trustees of the Fund who are not "interested persons" of
the Fund is committed to the discretion of the Independent Trustees. This
provision does not prevent the involvement of others in the selection and
nomination process as long as the final decision as to selection or nomination
is approved by a majority of the Independent Trustees.

Under the plans, no payment will be made to any recipient in any quarter
in which the aggregate net asset value of all Fund shares held by the recipient
for itself and its customers does not exceed a minimum amount, if any, that may
be set from time to time by a majority of the Fund's Independent Trustees.
Initially, the Board of Trustees has set the fees at the maximum rate allowed
under the plans and has set no minimum asset amount needed to qualify for
payments.

|_| 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 (they are referred to as "recipients")
for personal services and account maintenance services they provide for their
customers who hold Class A shares. The services include, among others, answering
customer inquiries about the Fund, assisting in establishing and maintaining
accounts in the Fund, making the Fund's investment plans available and providing
other services at the request of the Fund or the Distributor. The Distributor
makes payments to plan recipients quarterly at an annual rate not to exceed
0.15% of the average annual net assets of Class A shares held in accounts of the
service providers or their customers.

For the fiscal year ended July 31, 1998, payments under the Plan for Class
A shares totaled $101,032, all of which was paid by the Distributor to
recipients. That included $6,691 paid to an affiliate of the Distributor. Any
unreimbursed expenses the Distributor incurs with respect to Class A shares for
any fiscal year may not be recovered in subsequent years. The Distributor may
not use payments received under the Class A plan to pay any of its interest
expenses, carrying charges, other financial costs, or allocation of overhead.

|_| Class B and Class C Service and Distribution 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 plans during that period. The Class B and Class C plans
permit the Distributor to retain both the asset-based sales charges and the
service fee on shares or to pay recipients the service fee on a quarterly basis,
without payment in advance.

The Distributor is entitled under the service plans for Class B and Class
C shares to receive a service fee of up to 0.25% per year. The Board of Trustees
has set that fee at 0.15% per year. The Distributor presently intends to pay
recipients the service fee on Class B and Class C shares in advance for the
first year the shares are outstanding. After the first year shares are
outstanding, the Distributor makes payments quarterly on those shares. The
advance payment is based on the net asset value of shares sold. Shares purchased
by exchange do not qualify for an advance service fee payment. If Class B or
Class C shares are redeemed during the first year after their purchase, the
recipient of the service fees on those shares will be obligated to repay the
Distributor a pro rata portion of the advance payment made on those shares.

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. It pays the asset-based sales charge
as an ongoing commission to the dealer on Class C shares outstanding for a year
or more. If a dealer has a special agreement with the Distributor, the
Distributor will pay the Class B and/or Class C service fees and the asset-based
sales charge to the dealer quarterly in lieu of paying the sales commission and
service fee in advance at the time of purchase.

|_| pays sales commissions to authorized brokers and dealers at the time of
sale and pays service fees as described in the Prospectus,
|_| may finance payment of sales commissions and/or the advance of the service
fee payment to recipients under the plans, or may provide such financing
from its own resources or from the resources of an affiliate,
|_| employs personnel to support distribution of shares, and |_| bears the costs
of sales literature, advertising and prospectuses (other
than those furnished to current shareholders) and state "blue sky"
registration fees and certain other distribution expenses.

Payments made under the Class B plan for the fiscal year ended July 31,
1998, totaled $209,616 (including $1,930 paid to an affiliate of the
Distributor). The Distributor retained $164,757 of the total paid. Payments made
under the Class C Plan for the fiscal year ended July 31, 1998 totaled $40,557,
of which $27,981 was retained by the Distributor. At July 31, 1998, the
Distributor had incurred unreimbursed expenses under the Class B plan in the
amount of $597,509 (equal to 2.7% of the Fund's net assets represented by Class
B shares on that date). At July 31, 1998, the Distributor had incurred
unreimbursed expenses under the Class C plan of $51,599 (equal to 0.99% of the
Fund's net assets represented by Class C shares on that date). 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 the Distributor for distributing
shares before the plan was terminated.

All payments under the Class B and Class C plans are subject to the
limitations imposed by the Conduct Rules of the National Association of
Securities Dealers, Inc. on payments of asset-based sales charges and service
fees to NASD members.

Performance of the Fund

Explanation of Performance Terminology. The Fund uses a variety of terms to
illustrate its performance. These terms include "standardized yield,"
"tax-equivalent yield," "dividend yield," "average annual total return,"
"cumulative total return," "average annual total return at net asset value" and
"total return at net asset value." An explanation of how yields and total
returns are calculated is set forth below. The charts below show the Fund's
performance during its most recent fiscal year end. You can obtain current
performance information by calling the Fund's Transfer Agent at 1-800-525-7048
or by visiting the OppenheimerFunds Internet web site at
http://www.oppenheimerfunds.com.

The Fund's illustrations of its performance data in advertisements must
comply with rules of the Securities and Exchange Commission. Those rules
describe the types of performance data that may be used and how it is to be
calculated. In general, any advertisement by the Fund of its performance data
must include the average annual total returns for the advertised class of shares
of the Fund. Those returns must be shown for the 1, 5 and 10-year periods (or
the life of the class, if less) ending as of the most recently ended calendar
quarter prior to the publication of the advertisement (or its submission for
publication). Certain types of yields may also be shown, provided that they are
accompanied by standardized average annual total returns.

Use of standardized performance calculations enables an investor to
compare the Fund's performance to the performance of other funds for the same
periods. However, a number of factors should be considered before using the
Fund's performance information as a basis for comparison with other investments:

|_| Yields and total returns measure the performance of a hypothetical
account in the Fund over various periods and do not show the performance of each
shareholder's account. Your account's performance will vary from the model
performance data if your dividends are received in cash, or you buy or sell
shares during the period, or you bought your shares at a different time and
price than the shares used in the model.
|_| The Fund's performance returns do not reflect the effect of taxes
on distributions.
|_| An investment in the Fund is not insured by the FDIC or any other
government agency.
|_| The principal value of the Fund's shares, and its yields and total
returns are not guaranteed and normally will fluctuate on a daily basis.
|_| When an investor's shares are redeemed, they may be worth more or less
than their original cost.
|_| Yields and total returns for any given past period represent
historical performance information and are not, and should not be considered, a
prediction of future yields or returns.

The performance of each class of shares is shown separately, because the
performance of each class of shares will usually be different. That is because
of the different kinds of expenses each class bears. The yields and total
returns of each class of shares of the Fund are affected by market conditions,
the quality of the Fund's investments, the maturity of those investments, the
types of investments the Fund holds, and its operating expenses that are
allocated to the particular class.

|X| Yields. The Fund uses a variety of different yields to illustrate its
current returns. Each class of shares calculates its yield separately because of
the different expenses that affect each class.

|_| Standardized Yield. The "standardized yield" (sometimes referred to
just as "yield") is shown for a class of shares for a stated 30-day period. It
is not based on actual distributions paid by the Fund to shareholders in the
30-day period, but is a hypothetical yield based upon the net investment income
from the Fund's portfolio investments for that period. It may therefore differ
from the "dividend yield" for the same class of shares, described below.

Standardized yield is calculated using the following formula set forth in
rules adopted by the Securities and Exchange Commission, designed to assure
uniformity in the way that all funds calculate their yields:

Standardized Yield = 2[(a-b
--- + 1)6 - 1]
cd

The symbols above represent the following factors:
a =dividends and interest earned during the 30-day period.
b =expenses accrued for the period (net of any expense assumptions).
c =the average daily number of shares of that class outstanding during
the 30-day period that were entitled to receive dividends.
d =the maximum offering price per share of that class on the last day of
the period, adjusted for undistributed net investment income.

The standardized yield for a particular 30-day period may differ from the
yield for other periods. The SEC formula assumes that the standardized yield for
a 30-day period occurs at a constant rate for a six-month period and is
annualized at the end of the six-month period. Additionally, because each class
of shares is subject to different expenses, it is likely that the standardized
yields of the Fund's classes of shares will differ for any 30-day period.

|_| Dividend Yield. The Fund may quote a "dividend yield" for each class
of its shares. Dividend yield is based on the dividends paid on a class of
shares during the actual dividend period. To calculate dividend yield, the
dividends of a class declared during a stated period are added together, and the
sum is multiplied by 12 (to annualize the yield) and divided by the maximum
offering price on the last day of the dividend period. The formula is shown
below:

Dividend Yield = dividends paid x 12/maximum offering price
(payment date)

The maximum offering price for Class A shares includes the current maximum
initial sales charge. The maximum offering price for Class B and Class C shares
is the net asset value per share, without considering the effect of contingent
deferred sales charges. The Class A dividend yield may also be quoted without
deducting the maximum initial sales charge.

|_| Tax-Equivalent Yield. The "tax-equivalent yield" of a class of shares
is the equivalent yield that would have to be earned on a taxable investment to
achieve the after-tax results represented by the Fund's tax-equivalent yield. It
adjusts the Fund's standardized yield, as calculated above, by a stated Federal
tax rate. Using different tax rates to show different tax equivalent yields
shows investors in different tax brackets the tax equivalent yield of the Fund
based on their own tax bracket.

The tax-equivalent yield is based on a 30-day period, and is computed by
dividing the tax-exempt portion of the Fund's current yield (as calculated
above) by one minus a stated income tax rate. The result is added to the portion
(if any) of the Fund's current yield that is not tax-exempt.

The tax-equivalent yield may be used to compare the tax effects of income
derived from the Fund with income from taxable investments at the tax rates
stated. Your tax bracket is determined by your Federal and state taxable income
(the net amount subject to Federal and state income tax after deductions and
exemptions). The tax-equivalent yield table assumes that the investor is taxed
at the highest bracket, regardless of whether a switch to non-taxable
investments would cause a lower bracket to apply.

|X| Total Return Information. There are different types of "total returns"
to measure the Fund's performance. Total return is the change in value of a
hypothetical investment in the Fund over a given period, assuming that all
dividends and capital gains distributions are reinvested in additional shares
and that the investment is redeemed at the end of the period. Because of
differences in expenses for each class of shares, the total returns for each
class are separately measured. The cumulative total return measures the change
in value over the entire period (for example, ten years). An average annual
total return shows the average rate of return for each year in a period that
would produce the cumulative total return over the entire period. However,
average annual total returns do not show actual year-by-year performance. The
Fund uses standardized calculations for its total returns as prescribed by the
SEC. The methodology is discussed below.

In calculating total returns for Class A shares, the current maximum sales
charge of 4.75% (as a percentage of the offering price) is deducted from the
initial investment ("P") (unless the return is shown without sales charge, as
described below). For Class B shares, payment of the applicable contingent
deferred sales charge is applied, depending on the period for which the return
is shown: 5.0% in the first year, 4.0% in the second year, 3.0% in the third and
fourth years, 2.0% in the fifth year, 1.0% in the sixth year and none
thereafter. For Class C shares, the 1% contingent deferred sales charge is
deducted for returns for the 1-year period.

|_| Average Annual Total Return. The "average annual total return" of each
class is an average annual compounded rate of return for each year in a
specified number of years. It is the rate of return based on the change in value
of a hypothetical initial investment of $1,000 ("P" in the formula below) held
for a number of years ("n") to achieve an Ending Redeemable Value ("ERV" in the
formula) of that investment, according to the following formula:

ERV 1/n
--- - 1 = Average Annual Total Return
P

|_| Cumulative Total Return. The "cumulative total return" calculation
measures the change in value of a hypothetical investment of $1,000 over an
entire period of years. Its calculation uses some of the same factors as average
annual total return, but it does not average the rate of return on an annual
basis. Cumulative total return is determined as follows:

ERV-P
----- = Total Return
P

|_| Total Returns at Net Asset Value. From time to time the Fund may also
quote a cumulative or an average annual total return "at net asset value"
(without deducting sales charges) for Class A, Class B or Class C shares. Each
is based on the difference in net asset value per share at the beginning and the
end of the period for a hypothetical investment in that class of shares (without
considering front-end or contingent deferred sales charges) and takes into
consideration the reinvestment of dividends and capital gains distributions.

|_| Lipper Rankings. From time to time the Fund may publish the ranking of
the performance of its Class A, Class B or Class C shares by Lipper Analytical
Services, Inc. ("Lipper"). Lipper is a widely-recognized independent mutual fund
monitoring service. Lipper monitors the performance of regulated investment
companies, including the Fund, and ranks their performance for various periods
based on categories relating to investment objectives. The performance of the
Fund is ranked by Lipper against all other bond funds, other than money market
funds, and other municipal bond funds. The Lipper performance rankings are based
on total returns that include the reinvestment of capital gain distributions and
income dividends but do not take sales charges or taxes into consideration.
Lipper also publishes "peer-group" indices of the performance of all mutual
funds in a category that it monitors and averages of the performance of the
funds in particular categories.

|_| Morningstar Rankings. From time to time the Fund may publish the star
ranking of the performance of its Class A, Class B or Class C shares by
Morningstar, Inc., an independent mutual fund monitoring service. Morningstar
ranks mutual funds in broad investment categories: domestic stock funds,
international stock funds, taxable bond funds and municipal bond funds. The Fund
is ranked among municipal bond funds.

Morningstar star rankings are based on risk-adjusted total investment
return. Investment return measures a fund's (or class's) one, three, five and
ten-year average annual total returns (depending on the inception of the fund or
class) in excess of 90-day U.S. Treasury bill returns after considering the
fund's sales charges and expenses. Risk measures a fund's (or class's)
performance below 90-day U.S. Treasury bill returns. Risk and investment return
are combined to produce star rankings reflecting performance relative to the
average fund in a fund's category. Five stars is the "highest" ranking (top 10%
of funds in a category), four stars is "above average" (next 22.5%), three stars
is "average" (next 35%), two stars is "below average" (next 22.5%) and one star
is "lowest" (bottom 10%). The current star ranking is the fund's (or class's)
3-year ranking or its combined 3- and 5-year ranking (weighted 60%/40%
respectively), or its combined 3-, 5-, and 10-year ranking (weighted 40%, 30%
and 30%, respectively), depending on the inception date of the fund (or class).
Rankings are subject to change monthly.

The Fund may also compare its performance to that of other funds in its
Morningstar category. In addition to its star rankings, Morningstar also
categorizes and compares a fund's 3-year performance based on Morningstar's
classification of the fund's investments and investment style, rather than how a
fund defines its investment objective. Morningstar's four broad categories
(domestic equity, international equity, municipal bond and taxable bond) are
each further subdivided into categories based on types of investments and
investment styles. Those comparisons by Morningstar are based on the same risk
and return measurements as its star rankings but do not consider the effect of
sales charges.

|_| Performance Rankings and Comparisons by Other Entities and
Publications. From time to time the Fund may include in its advertisements and
sales literature performance information about the Fund cited in newspapers and
other periodicals such as The New York Times, the Wall Street Journal, Barron's,
or similar publications. That information may include performance quotations
from other sources, including Lipper and Morningstar. The performance of the
Fund's Class A, Class B or Class C shares may be compared in publications to the
performance of various market indices or other investments, and averages,
performance rankings or other benchmarks prepared by recognized mutual fund
statistical services.

Investors may also wish to compare the Fund's Class A, Class B or Class C
returns to the return on fixed-income investments available from banks and
thrift institutions. Those include certificates of deposit, ordinary
interest-paying checking and savings accounts, and other forms of fixed or
variable time deposits, and various other instruments such as Treasury bills.
However, the Fund's returns and share price are not guaranteed or insured by the
FDIC or any other agency and will fluctuate daily, while bank depository
obligations may be insured by the FDIC and may provide fixed rates of return.
Repayment of principal and payment of interest on Treasury securities is backed
by the full faith and credit of the U.S. government.

From time to time, the Fund may publish rankings or ratings of the Manager
or Transfer Agent, and of the investor services provided by them to shareholders
of the Oppenheimer funds, other than performance rankings of the Oppenheimer
funds themselves. Those ratings or rankings of shareholder and investor services
by third parties may include comparisons of their services to those provided by
other mutual fund families selected by the rating or ranking services. They may
be based upon the opinions of the rating or ranking service itself, using its
research or judgment, or based upon surveys of investors, brokers, shareholders
or others.

How to Buy Shares

Additional information is presented below about the methods that can be
used to buy shares of the Fund. Appendix C contains more information about the
special sales charge arrangements offered by the Fund, and the circumstances in
which sales charges may be reduced or waived for certain classes of investors.

AccountLink. When shares are purchased through AccountLink, each purchase must
be at least $25. Shares will be purchased on the regular business day the
Distributor is instructed to initiate the Automated Clearing House ("ACH")
transfer to buy the shares. Dividends will begin to accrue on shares purchased
with the proceeds of ACH transfers on the business day the Fund receives Federal
Funds for the purchase through the ACH system before the close of The New York
Stock Exchange. The Exchange normally closes at 4:00 P.M., but may close earlier
on certain days. If Federal Funds are received on a business day after the close
of the Exchange, the shares will be purchased and dividends will begin to accrue
on the next regular business day. The proceeds of ACH transfers are normally
received by the Fund 3 days after the transfers are initiated. The Distributor
and the Fund are not responsible for any delays in purchasing shares resulting
from delays in ACH transmissions.

Reduced Sales Charges. As discussed in the Prospectus, a reduced sales charge
rate may be obtained for Class A shares under Right of Accumulation and Letters
of Intent because of the economies of sales efforts and reduction in expenses
realized by the Distributor, dealers and brokers making such sales. No sales
charge is imposed in certain other circumstances described in Appendix C to this
Statement of Additional Information because the Distributor or dealer or broker
incurs little or no selling expenses.

|X| Right of Accumulation. To qualify for the lower sales charge rates
that apply to larger purchases of Class A shares, you and your spouse can add
together:
|_| Class A and Class B shares you purchase for your individual
accounts, or for your joint accounts, or for trust or custodial
accounts on behalf of your children who are minors, and
|_|current purchases of Class A and Class B shares of the Fund and other
Oppenheimer funds to reduce the sales charge rate that applies to
current purchases of Class A shares, and
|_|Class A and Class B shares of Oppenheimer funds you previously
purchased subject to an initial or contingent deferred sales charge
to reduce the sales charge rate for current purchases of Class A
shares, provided that you still hold your investment in one of the
Oppenheimer funds.

A fiduciary can count all shares purchased for a trust, estate or other
fiduciary account (including one or more employee benefit plans of the same
employer) that has multiple accounts. The Distributor will add the value, at
current offering price, of the shares you previously purchased and currently own
to the value of current purchases to determine the sales charge rate that
applies. The reduced sales charge will apply only to current purchases. You must
request it when you buy shares.

There is an initial sales charge on the purchase of Class A shares of each
of the Oppenheimer funds except the money market funds. Under certain
circumstances described in this Statement of Additional Information, redemption
proceeds of certain money market fund shares may be subject to a contingent
deferred sales charge.

Letters of Intent. Under a Letter of Intent, if you purchase Class A shares or
Class A and Class B shares of the Fund and other Oppenheimer funds during a
13-month period, you can reduce the sales charge rate that applies to your
purchases of Class A shares. The total amount of your intended purchases of both
Class A and Class B shares will determine the reduced sales charge rate for the
Class A shares purchased during that period. You can include purchases made up
to 90 days before the date of the Letter.

A Letter of Intent is an investor's statement in writing to the
Distributor of the intention to purchase Class A shares or Class A and Class B
shares of the Fund (and other Oppenheimer funds) during a 13-month period (the
"Letter of Intent period"). At the investor's request, this may include
purchases made up to 90 days prior to the date of the Letter. The Letter states
the investor's intention to make the aggregate amount of purchases of shares
which, when added to the investor's holdings of shares of those funds, will
equal or exceed the amount specified in the Letter. Purchases made by
reinvestment of dividends or distributions of capital gains and purchases made
at net asset value without sales charge do not count toward satisfying the
amount of the Letter.

A Letter enables an investor to count the Class A and Class B shares
purchased under the Letter to obtain the reduced sales charge rate on purchases
of Class A shares of the Fund (and other Oppenheimer funds) that applies under
the Right of Accumulation to current purchases of Class A shares. Each purchase
of Class A shares under the Letter will be made at the public offering price
(including the sales charge) that applies to a single lump-sum purchase of
shares in the amount intended to be purchased under the Letter.

In submitting a Letter, the investor makes no commitment to purchase
shares. However, if the investor's purchases of shares within the Letter of
Intent period, when added to the value (at offering price) of the investor's
holdings of shares on the last day of that period, do not equal or exceed the
intended purchase amount, the investor agrees to pay the additional amount of
sales charge applicable to such purchases. That amount is described in "Terms of
Escrow," below (those terms may be amended by the Distributor from time to
time). The investor agrees that shares equal in value to 5% of the intended
purchase amount will be held in escrow by the Transfer Agent subject to the
Terms of Escrow. Also, the investor agrees to be bound by the terms of the
Prospectus, this Statement of Additional Information and the Application used
for a Letter of Intent. If those terms are amended, as they may be from time to
time by the Fund, the investor agrees to be bound by the amended terms and that
those amendments will apply automatically to existing Letters of Intent.

If the total eligible purchases made during the Letter of Intent period do
not equal or exceed the intended purchase amount, the commissions previously
paid to the dealer of record for the account and the amount of sales charge
retained by the Distributor will be adjusted to the rates applicable to actual
total purchases. If total eligible purchases during the Letter of Intent period
exceed the intended purchase amount and exceed the amount needed to qualify for
the next sales charge rate reduction set forth in the Prospectus, the sales
charges paid will be adjusted to the lower rate. That adjustment will be made
only if and when the dealer returns to the Distributor the excess of the amount
of commissions allowed or paid to the dealer over the amount of commissions that
apply to the actual amount of purchases. The excess commissions returned to the
Distributor will be used to purchase additional shares for the investor's
account at the net asset value per share in effect on the date of such purchase,
promptly after the Distributor's receipt thereof.

In determining the total amount of purchases made under a Letter, shares
redeemed by the investor prior to the termination of the Letter of Intent period
will be deducted. It is the responsibility of the dealer of record and/or the
investor to advise the Distributor about the Letter in placing any purchase
orders for the investor during the Letter of Intent period. All of such
purchases must be made through the Distributor.

|_| Terms of Escrow That Apply to Letters of Intent.

1. Out of the initial purchase (or subsequent purchases if necessary) made
pursuant to a Letter, shares of the Fund equal in value up to 5% of the intended
purchase amount specified in the Letter shall be held in escrow by the Transfer
Agent. For example, if the intended purchase amount is $50,000, the escrow shall
be shares valued in the amount of $2,500 (computed at the public offering price
adjusted for a $50,000 purchase). Any dividends and capital gains distributions
on the escrowed shares will be credited to the investor's account.

2. If the total minimum investment specified under the Letter is completed
within the thirteen-month Letter of Intent period, the escrowed shares will be
promptly released to the investor.

3. If, at the end of the thirteen-month Letter of Intent period the total
purchases pursuant to the Letter are less than the intended purchase amount
specified in the Letter, the investor must remit to the Distributor an amount
equal to the difference between the dollar amount of sales charges actually paid
and the amount of sales charges which would have been paid if the total amount
purchased had been made at a single time. That sales charge adjustment will
apply to any shares redeemed prior to the completion of the Letter. If the
difference in sales charges is not paid within twenty days after a request from
the Distributor or the dealer, the Distributor will, within sixty days of the
expiration of the Letter, redeem the number of escrowed shares necessary to
realize such difference in sales charges. Full and fractional shares remaining
after such redemption will be released from escrow. If a request is received to
redeem escrowed shares prior to the payment of such additional sales charge, the
sales charge will be withheld from the redemption proceeds.

4. By signing the Letter, the investor irrevocably constitutes and
appoints the Transfer Agent as attorney-in-fact to surrender for redemption any
or all escrowed shares.

5. The shares eligible for purchase under the Letter (or the holding of
which may be counted toward completion of a Letter) include:
(a) Class A shares sold with a front-end sales charge or subject to a
Class A contingent deferred sales charge,
(b) Class B shares of other Oppenheimer funds acquired subject to a
contingent deferred sales charge, and
(c) Class A or Class B shares acquired by exchange of either (1) Class A
shares of one of the other Oppenheimer funds that were acquired
subject to a Class A initial or contingent deferred sales charge or
(2) Class B shares of one of the other Oppenheimer funds that were
acquired subject to a contingent deferred sales charge.

6. Shares held in escrow hereunder will automatically be exchanged for
shares of another fund to which an exchange is requested, as described in the
section of the Prospectus entitled "How to Exchange Shares" and the escrow will
be transferred to that other fund.

Asset Builder Plans. To establish an Asset Builder Plan to buy shares directly
from a bank account, you must enclose a check (minimum $25) for the initial
purchase with your application. Shares purchased by Asset Builder Plan payments
from bank accounts are subject to the redemption restrictions for recent
purchases described in the Prospectus. Asset Builder Plans also enable
shareholders of Oppenheimer Cash Reserves to use their fund account to make
monthly automatic purchases of shares of up to four other Oppenheimer funds.

If you make payments from your bank account to purchase shares of the
Fund, your bank account will be automatically debited, normally four to five
business days prior to the investment dates selected in the Application. Neither
the Distributor, the Transfer Agent nor the Fund shall be responsible for any
delays in purchasing shares resulting from delays in ACH transmission.

Before initiating Asset Builder payments, obtain a prospectus of the
selected fund(s) from the Distributor or your financial advisor and request an
application from the Distributor, complete it and return it. The amount of the
Asset Builder investment may be changed or the automatic investments may be
terminated at any time by writing to the Transfer Agent. The Transfer Agent
requires a reasonable period (approximately 15 days) after receipt of such
instructions to implement them. The Fund reserves the right to amend, suspend,
or discontinue offering Asset Builder plans at any time without prior notice.

Cancellation of Purchase Orders. Cancellation of purchase orders for the Fund's
shares (for example, when a purchase check is returned to the Fund unpaid)
causes a loss to be incurred when the net asset value of the Fund's shares on
the cancellation date is less than on the purchase date. That loss is equal to
the amount of the decline in the net asset value per share multiplied by the
number of shares in the purchase order. The investor is responsible for that
loss. If the investor fails to compensate the Fund for the loss, the Distributor
will do so. The Fund may reimburse the Distributor for that amount by redeeming
shares from any account registered in that investor's name, or the Fund or the
Distributor may seek other redress.

Classes of Shares. Each class of shares of the Fund represents an interest in
the same portfolio of investments of the Fund. However, each class has different
shareholder privileges and features. The net income attributable to Class B or
Class C shares and the dividends payable on Class B or Class C shares will be
reduced by incremental expenses borne solely by that class. Those expenses
include the asset-based sales charges to which Class B and Class C are subject.

The availability of three classes of shares permits an investor to choose
the method of purchasing shares that is more appropriate for the investor. That
may depend on the amount of the purchase, the length of time the investor
expects to hold shares, and other relevant circumstances. Class A shares in
general are sold subject to an initial sales charge. While Class B and Class C
shares have no initial sales charge, the purpose of the deferred sales charge
and asset-based sales charge on Class B and Class C shares is the same as that
of the initial sales charge on Class A shares - to compensate the Distributor
and brokers, dealers and financial institutions that sell shares of the Fund. A
salesperson who is entitled to receive compensation for selling Fund shares may
receive different levels of compensation for selling to one class of shares than
another.

The Distributor will not accept any order in the amount of $500,000 or
more for Class B shares or $1 million or more for Class C shares on behalf of a
single investor (not including dealer "street name" or omnibus accounts). That
is because generally it will be more advantageous for that investor to purchase
Class A shares of the Fund.

|_| Class B Conversion. The conversion of Class B shares to Class A shares
after six years is subject to the continuing availability of a private letter
ruling from the Internal Revenue Service, or an opinion of counsel or tax
adviser, to the effect that the conversion of Class B shares does not constitute
a taxable event for the holder under Federal income tax law. If such a revenue
ruling or opinion is no longer available, the automatic conversion feature may
be suspended, in which event no further conversions of Class B shares would
occur while such suspension remained in effect. Although Class B shares could
then be exchanged for Class A shares on the basis of relative net asset value of
the two classes, without the imposition of a sales charge or fee, such exchange
could constitute a taxable event for the holder, and absent such exchange, Class
B shares might continue to be subject to the asset-based sales charge for longer
than six years. Shareholders should consult their tax advisors regarding the
state and local tax consequences of the conversion of Class B shares into Class
A shares, or any other conversion or exchange of shares.

|_| Allocation of Expenses. The Fund pays expenses related to its daily
operations, such as custodian fees, trustees' fees, transfer agency fees, legal
fees and auditing costs. Those expenses are paid out of the Fund's assets and
are not paid directly by shareholders. However, those expenses reduce the net
asset value of shares, and therefore are indirectly borne by shareholders
through their investment.

The methodology for calculating the net asset value, dividends and
distributions of the Fund's share classes recognizes two types of expenses.
General expenses that do not pertain specifically to any one class are allocated
pro rata to the shares of all classes. The allocation is based on the percentage
of the Fund's total assets that is represented by the assets of each class, and
then equally to each outstanding share within a given class. Such general
expenses include management fees, legal, bookkeeping and audit fees, printing
and mailing costs of shareholder reports, Prospectuses, Statements of Additional
Information and other materials for current shareholders, fees to unaffiliated
Trustees, custodian expenses, share issuance costs, organization and start-up
costs, interest, taxes and brokerage commissions, and non-recurring expenses,
such as litigation costs.

Other expenses that are directly attributable to a particular class are
allocated equally to each outstanding share within that class. Examples of such
expenses include distribution and service plan (12b-1) fees, transfer and
shareholder servicing agent fees and expenses, share registration fees and
shareholder meeting expenses (to the extent that such expenses pertain only to a
specific class).

Determination of Net Asset Values Per Share. The net asset values per share of
each class of shares of the Fund are determined as of the close of business of
The New York Stock Exchange on each day that the Exchange is open. It is done by
dividing the value of the Fund's net assets attributable to that class by the
number of shares of that class that are outstanding. The Exchange normally
closes at 4:00 P.M., New York time, but may close earlier on some other days
(for example, in case of weather emergencies or on days falling before a
holiday). The Exchange's most recent annual announcement (which is subject to
change) states that it will close on New Year's Day, Martin Luther King, Jr.
Day, Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day,
Thanksgiving Day and Christmas Day. It may also close on other days.

Dealers other than Exchange members may conduct trading in municipal
securities on days on which the Exchange is closed (including weekends and
holidays) or after 4:00 P.M. on a regular business day. Because the Fund's net
asset values will not be calculated on those days, the Fund's net asset values
per share may be significantly affected on such days when shareholders may not
purchase or redeem shares.

|X| Securities Valuation. The Fund's Board of Trustees has established
procedures for the valuation of the Fund's securities. In general those
procedures are as follows:

|_| Long-term debt securities having a remaining maturity in excess of 60
days are valued based on the mean between the "bid" and "asked" prices
determined by a portfolio pricing service approved by the Fund's Board of
Trustees or obtained by the Manager from two active market makers in the
security on the basis of reasonable inquiry.
|_| The following securities are valued at the mean between the "bid" and
"asked" prices determined by a pricing service approved by the Fund's Board of
Trustees or obtained by the Manager from two active market makers in the
security on the basis of reasonable inquiry: (1) debt instruments that have a
maturity of more than 397 days when issued, (2) debt instruments that had a
maturity of 397 days or less when issued and
have a remaining maturity of more than 60 days, and (3) non-money market
debt instruments that had a maturity of 397 days or
less when issued and which have a remaining maturity of 60 days or less.
|_| The following securities are valued at cost, adjusted for
amortization of premiums and accretion of discounts:
(1) money market debt securities held by a non-money market fund that had a
maturity of less than 397 days when issued that have a remaining
maturity of 60 days or less, and
(2) debt instruments held by a money market fund that have a remaining
maturity of 397 days or less.
|_| Securities not having readily-available market quotations are valued
at fair value determined under the Board's procedures.

If the Manager is unable to locate two market makers willing to give
quotes, a security may be priced at the mean between the "bid" and "asked"
prices provided by a single active market maker (which in certain cases may be
the "bid" price if no "asked" price is available).

In the case of municipal securities, when last sale information is not
generally available, the Manager may use pricing services approved by the Board
of Trustees. The pricing service may use "matrix" comparisons to the prices for
comparable instruments on the basis of quality, yield, maturity. Other special
factors may be involved (such as the tax-exempt status of the interest paid by
municipal securities). The Manager will monitor the accuracy of the pricing
services. That monitoring may include comparing prices used for portfolio
valuation to actual sales prices of selected securities.

Puts, calls, Interest Rate Futures and Municipal Bond Index Futures are
valued at the last sale price on the principal exchange on which they are traded
or on NASDAQ, as applicable, as determined by a pricing service approved by the
Board of Trustees or by the Manager. If there were no sales that day, they shall
be valued at the last sale price on the preceding trading day if it is within
the spread of the closing "bid" and "asked" prices on the principal exchange or
on NASDAQ on the valuation date. If not, the value shall be the closing bid
price on the principal exchange or on NASDAQ on the valuation date. If the put,
call or future is not traded on an exchange or on NASDAQ, it shall be valued by
the mean between "bid" and "asked" prices obtained by the Manager from two
active market makers. In certain cases that may be at the "bid" price if no
"asked" price is available.

When the Fund writes an option, an amount equal to the premium received is
included in the Fund's Statement of Assets and Liabilities as an asset. An
equivalent credit is included in the liability section. The credit is adjusted
("marked-to-market") to reflect the current market value of the option. In
determining the Fund's gain on investments, if a call or put written by the Fund
is exercised, the proceeds are increased by the premium received. If a call or
put written by the Fund expires, the Fund has a gain in the amount of the
premium. If the Fund enters into a closing purchase transaction, it will have a
gain or loss, depending on whether the premium received was more or less than
the cost of the closing transaction. If the Fund exercises a put it holds, the
amount the Fund receives on its sale of the underlying investment is reduced by
the amount of premium paid by the Fund.

How to Sell Shares

The information below supplements the terms and conditions for redeeming
shares set forth in the Prospectus.

In choosing to take advantage of the Checkwriting privilege by signing the
Account Application or by completing a Checkwriting card, each individual who
signs: (1) for individual accounts, represents that they are the registered
owner(s) of the shares of the Fund in that account;
(2) for accounts for corporations, partnerships, trusts and other entities,
represents that they are an officer, general partner, trustee or other
fiduciary or agent, as applicable, duly authorized to act on behalf of
such registered owner(s);
(3) authorizes the Fund, its Transfer Agent and any bank through which the
Fund's drafts (checks) are payable to pay all checks drawn on the Fund
account of such person(s) and to redeem a sufficient amount of shares
from that account to cover payment of each check;
(4) specifically acknowledges that if they choose to permit checks to be
honored if there is a single signature on checks drawn against joint
accounts, or accounts for corporations, partnerships, trusts or other
entities, the signature of any one signatory on a check will be
sufficient to authorize payment of that check and redemption from the
account, even if that account is registered in the names of more than
one person or more than one authorized signature appears on the
Checkwriting card or the Application, as applicable;
(5) understands that the Checkwriting privilege may be terminated or amended
at any time by the Fund and/or the Fund's bank; and
(6) acknowledges and agrees that neither the Fund nor its bank shall incur
any liability for that amendment or termination of checkwriting
privileges or for redeeming shares to pay checks reasonably believed by
them to be genuine, or for returning or not paying checks that have not
been accepted for any reason.

The reinvestment may be made without sales charge only in Class A shares
of the Fund or any of the other Oppenheimer funds into which shares of the Fund
are exchangeable as described in "How to Exchange Shares" below. Reinvestment
will be at the net asset value next computed after the Transfer Agent receives
the reinvestment order. The shareholder must ask the Transfer Agent for that
privilege at the time of reinvestment. This privilege does not apply to Class C
shares. The Fund may amend, suspend or cease offering this reinvestment
privilege at any time as to shares redeemed after the date of such amendment,
suspension or cessation.

Any capital gain that was realized when the shares were redeemed is
taxable, and reinvestment will not alter any capital gains tax payable on that
gain. If there has been a capital loss on the redemption, some or all of the
loss may not be tax deductible, depending on the timing and amount of the
reinvestment. Under the Internal Revenue Code, if the redemption proceeds of
Fund shares on which a sales charge was paid are reinvested in shares of the
Fund or another of the Oppenheimer funds within 90 days of payment of the sales
charge, the shareholder's basis in the shares of the Fund that were redeemed may
not include the amount of the sales charge paid. That would reduce the loss or
increase the gain recognized from the redemption. However, in that case the
sales charge would be added to the basis of the shares acquired by the
reinvestment of the redemption proceeds.

Payments "In Kind". The Prospectus states that payment for shares tendered for
redemption is ordinarily made in cash. However, the Board of Trustees of the
Fund may determine that it would be detrimental to the best interests of the
remaining shareholders of the Fund to make payment of a redemption order wholly
or partly in cash. In that case, the Fund may pay the redemption proceeds in
whole or in part by a distribution "in kind" of securities from the portfolio of
the Fund, in lieu of cash.

The Fund has elected to be governed by Rule 18f-1 under the Investment
Company Act. Under that rule, the Fund is obligated to redeem shares solely in
cash up to the lesser of $250,000 or 1% of the net assets of the Fund during any
90-day period for any one shareholder. If shares are redeemed in kind, the
redeeming shareholder might incur brokerage or other costs in selling the
securities for cash. The Fund will value securities used to pay redemptions in
kind using the same method the Fund uses to value its portfolio securities
described above under "Determination of Net Asset Values Per Share." That
valuation will be made as of the time the redemption price is determined.

Involuntary Redemptions. The Fund's Board of Trustees has the right to cause the
involuntary redemption of the shares held in any account if the aggregate net
asset value of those shares is less than $200 or such lesser amount as the Board
may fix. The Board of Trustees will not cause the involuntary redemption of
shares in an account if the aggregate net asset value of such shares has fallen
below the stated minimum solely as a result of market fluctuations. If the Board
exercises this right, it may also fix the requirements for any notice to be
given to the shareholders in question (not less than 30 days). The Board may
alternatively set requirements for the shareholder to increase the investment,
or set other terms and conditions so that the shares would not be involuntarily
redeemed.

Transfers of Shares. A transfer of shares to a different registration is not an
event that triggers the payment of sales charges. Therefore, shares are not
subject to the payment of a contingent deferred sales charge of any class at the
time of transfer to the name of another person or entity. It does not matter
whether the transfer occurs by absolute assignment, gift or bequest, as long as
it does not involve, directly or indirectly, a public sale of the shares. When
shares subject to a contingent deferred sales charge are transferred, the
transferred shares will remain subject to the contingent deferred sales charge.
It will be calculated as if the transferee shareholder had acquired the
transferred shares in the same manner and at the same time as the transferring
shareholder.

If less than all shares held in an account are transferred, and some but
not all shares in the account would be subject to a contingent deferred sales
charge if redeemed at the time of transfer, the priorities described in the
Prospectus under "How to Buy Shares" for the imposition of the Class B or Class
C contingent deferred sales charge will be followed in determining the order in
which shares are transferred.

Special Arrangements for Repurchase of Shares from Dealers and Brokers. The
Distributor is the Fund's agent to repurchase its shares from authorized dealers
or brokers on behalf of their customers. Shareholders should contact their
broker or dealer to arrange this type of redemption. The repurchase price per
share will be the net asset value next computed after the Distributor receives
an order placed by the dealer or broker. However, if the Distributor receives a
repurchase order from a dealer or broker after the close of The New York Stock
Exchange on a regular business day, it will be processed at that day's net asset
value if the order was received by the dealer or broker from its customers prior
to the time the Exchange closes. Normally, the Exchange closes at 4:00 P.M., but
may do so earlier on some days. Additionally, the order must have been
transmitted to and received by the Distributor prior to its close of business
that day (normally 5:00 P.M.).

Ordinarily, for accounts redeemed by a broker-dealer under this procedure,
payment will be made within three business days after the shares have been
redeemed upon the Distributor's receipt of the required redemption documents in
proper form. The signature(s) of the registered owners on the redemption
documents must be guaranteed as described in the Prospectus.

Automatic Withdrawal and Exchange Plans. Investors owning shares of the Fund
valued at $5,000 or more can authorize the Transfer Agent to redeem shares
(having a value of at least $50) automatically on a monthly, quarterly,
semi-annual or annual basis under an Automatic Withdrawal Plan. Shares will be
redeemed three business days prior to the date requested by the shareholder for
receipt of the payment. Automatic withdrawals of up to $1,500 per month may be
requested by telephone if payments are to be made by check payable to all
shareholders of record. Payments must also be sent to the address of record for
the account and the address must not have been changed within the prior 30 days.
Required minimum distributions from OppenheimerFunds-sponsored retirement plans
may not be arranged on this basis.

Payments are normally made by check, but shareholders having AccountLink
privileges (see "How To Buy Shares") may arrange to have Automatic Withdrawal
Plan payments transferred to the bank account designated on the Account
Application or by signature-guaranteed instructions to the Transfer Agent.
Shares are normally redeemed pursuant to an Automatic Withdrawal Plan three
business days before the payment transmittal date you select in the Account
Application. If a contingent deferred sales charge applies to the redemption,
the amount of the check or payment will be reduced accordingly.

The Fund cannot guarantee receipt of a payment on the date requested. The
Fund reserves the right to amend, suspend or discontinue offering these plans at
any time without prior notice. Because of the sales charge assessed on Class A
share purchases, shareholders should not make regular additional Class A share
purchases while participating in an Automatic Withdrawal Plan. Class B and Class
C shareholders should not establish withdrawal plans, because of the imposition
of the contingent deferred sales charge on such withdrawals (except where the
contingent deferred sales charge is waived as described in "Waivers of Class B
and Class C Sales Charges" below).

By requesting an Automatic Withdrawal or Exchange Plan, the shareholder
agrees to the terms and conditions that apply to such plans, as stated below.
These provisions may be amended from time to time by the Fund and/or the
Distributor. When adopted, any amendments will automatically apply to existing
Plans.

|X| Automatic Exchange Plans. Shareholders can authorize the Transfer
Agent to exchange a pre-determined amount of shares of the Fund for shares (of
the same class) of other Oppenheimer funds automatically on a monthly,
quarterly, semi-annual or annual basis under an Automatic Exchange Plan. The
minimum amount that may be exchanged to each other fund account is $25.
Instructions should be provided on the OppenheimerFunds Application or
signature-guaranteed instructions. Exchanges made under these plans are subject
to the restrictions that apply to exchanges as set forth in "How to Exchange
Shares" in the Prospectus and below in this Statement of Additional Information.

|X| Automatic Withdrawal Plans. Fund shares will be redeemed as necessary
to meet withdrawal payments. Shares acquired without a sales charge will be
redeemed first. Shares acquired with reinvested dividends and capital gains
distributions will be redeemed next, followed by shares acquired with a sales
charge, to the extent necessary to make withdrawal payments. Depending upon the
amount withdrawn, the investor's principal may be depleted. Payments made under
these plans should not be considered as a yield or income on your investment.

The Transfer Agent will administer the investor's Automatic Withdrawal
Plan as agent for the shareholder(s) (the "Planholder") who executed the Plan
authorization and application submitted to the Transfer Agent. Neither the Fund
nor the Transfer Agent shall incur any liability to the Planholder for any
action taken or not taken by the Transfer Agent in good faith to administer the
Plan. Share certificates will not be issued for shares of the Fund purchased for
and held under the Plan, but the Transfer Agent will credit all such shares to
the account of the Planholder on the records of the Fund. Any share certificates
held by a Planholder may be surrendered unendorsed to the Transfer Agent with
the Plan application so that the shares represented by the certificate may be
held under the Plan.

For accounts subject to Automatic Withdrawal Plans, distributions of
capital gains must be reinvested in shares of the Fund, which will be done at
net asset value without a sales charge. Dividends on shares held in the account
may be paid in cash or reinvested.

Shares will be redeemed to make withdrawal payments at the net asset value
per share determined on the redemption date. Checks or AccountLink payments
representing the proceeds of Plan withdrawals will normally be transmitted three
business days prior to the date selected for receipt of the payment, according
to the choice specified in writing by the Planholder. Receipt of payment on the
date selected cannot be guaranteed.

The amount and the interval of disbursement payments and the address to
which checks are to be mailed or AccountLink payments are to be sent may be
changed at any time by the Planholder by writing to the Transfer Agent. The
Planholder should allow at least two weeks' time after mailing such notification
for the requested change to be put in effect. The Planholder may, at any time,
instruct the Transfer Agent by written notice to redeem all, or any part of, the
shares held under the Plan. That notice must be in proper form in accordance
with the requirements of the then-current Prospectus of the Fund. In that case,
the Transfer Agent will redeem the number of shares requested at the net asset
value per share in effect and will mail a check for the proceeds to the
Planholder.

The Planholder may terminate a Plan at any time by writing to the Transfer
Agent. The Fund may also give directions to the Transfer Agent to terminate a
Plan. The Transfer Agent will also terminate a Plan upon its receipt of evidence
satisfactory to it that the Planholder has died or is legally incapacitated.
Upon termination of a Plan by the Transfer Agent or the Fund, shares that have
not been redeemed will be held in uncertificated form in the name of the
Planholder. The account will continue as a dividend-reinvestment, uncertificated
account unless and until proper instructions are received from the Planholder,
his or her executor or guardian, or another authorized person.

To use shares held under the Plan as collateral for a debt, the Planholder
may request issuance of a portion of the shares in certificated form. Upon
written request from the Planholder, the Transfer Agent will determine the
number of shares for which a certificate may be issued without causing the
withdrawal checks to stop. However, should such uncertificated shares become
exhausted, Plan withdrawals will terminate.

If the Transfer Agent ceases to act as transfer agent for the Fund, the
Planholder will be deemed to have appointed any successor transfer agent to act
as agent in administering the Plan.

How to Exchange Shares

As stated in the Prospectus, shares of a particular class of Oppenheimer
funds having more than one class of shares may be exchanged only for shares of
the same class of other Oppenheimer funds. Shares of Oppenheimer funds that have
a single class without a class designation are deemed "Class A" shares for this
purpose. You can obtain a current list showing which funds offer which classes
by calling the Distributor at 1-800-525-7048.
|_| All of the Oppenheimer funds currently offer Class A, B and C shares
except Oppenheimer Money Market Fund, Inc., Centennial Money Market Trust,
Centennial Tax Exempt Trust, Centennial Government Trust, Centennial New York
Tax Exempt Trust, Centennial California Tax Exempt Trust, and Centennial America
Fund, L.P., which only offer Class A shares.
|_| Oppenheimer Main Street California Municipal Fund currently offers
only Class A and Class B shares.
|_| Class B and Class C shares of Oppenheimer Cash Reserves are generally
available only by exchange from the same class of shares of other Oppenheimer
funds or through OppenheimerFunds sponsored 401 (k) plans
|_| Class Y shares of Oppenheimer Real Asset Fund are not exchangeable.

Shares of Oppenheimer Money Market Fund, Inc. purchased with the
redemption proceeds of shares of other mutual funds (other than funds managed by
the Manager or its subsidiaries) redeemed within the 30 days prior to that
purchase may subsequently be exchanged for shares of other Oppenheimer funds
without being subject to an initial or contingent deferred sales charge. To
qualify for that privilege, the investor or the investor's dealer must notify
the Distributor of eligibility for this privilege at the time the shares of
Oppenheimer Money Market Fund, Inc. are purchased. If requested, they must
supply proof of entitlement to this privilege.

For accounts established on or before March 8, 1996 holding Class M shares
of Oppenheimer Convertible Securities Fund, Class M shares can be exchanged only
for Class A shares of other Oppenheimer funds. Exchanges to Class M shares of
Oppenheimer Convertible Securities Fund are permitted from Class A shares of
Oppenheimer Money Market Fund, Inc. or Oppenheimer Cash Reserves that were
acquired by exchange of Class M shares. No other exchanges may be made to Class
M shares.

|_| How Exchanges Affect Contingent Deferred Sales Charges. No contingent
deferred sales charge is imposed on exchanges of shares of any class purchased
subject to a contingent deferred sales charge. However, when Class A shares
acquired by exchange of Class A shares of other Oppenheimer funds purchased
subject to a Class A contingent deferred sales charge are redeemed within 18
months of the end of the calendar month of the initial purchase of the exchanged
Class A shares, the Class A contingent deferred sales charge is imposed on the
redeemed shares. The Class B contingent deferred sales charge is imposed on
Class B shares acquired by exchange if they are redeemed within 6 years of the
initial purchase of the exchanged Class B shares. The Class C contingent
deferred sales charge is imposed on Class C shares acquired by exchange if they
are redeemed within 12 months of the initial purchase of the exchanged Class C
shares.

When Class B or Class C shares are redeemed to effect an exchange, the
priorities described in "How To Buy Shares" in the Prospectus for the imposition
of the Class B or the Class C contingent deferred sales charge will be followed
in determining the order in which the shares are exchanged. Before exchanging
shares, shareholders should take into account how the exchange may affect any
contingent deferred sales charge that might be imposed in the subsequent
redemption of remaining shares. Shareholders owning shares of more than one
Class must specify whether they intend to exchange Class A, Class B or Class C
shares.

|_| Limits on Multiple Exchange Orders. The Fund reserves the right to
reject telephone or written exchange requests submitted in bulk by anyone on
behalf of more than one account. The Fund may accept requests for exchanges of
up to 50 accounts per day from representatives of authorized dealers that
qualify for this privilege.

|_| Telephone Exchange Requests. When exchanging shares by telephone, a
shareholder must have an existing account in the fund to which the exchange is
to be made. Otherwise, the investors must obtain a Prospectus of that fund
before the exchange request may be submitted. For full or partial exchanges of
an account made by telephone, any special account features such as Asset Builder
Plans and Automatic Withdrawal Plans will be switched to the new account unless
the Transfer Agent is instructed otherwise. If all telephone lines are busy
(which might occur, for example, during periods of substantial market
fluctuations), shareholders might not be able to request exchanges by telephone
and would have to submit written exchange requests.

|_| Processing Exchange Requests. Shares to be exchanged are redeemed on
the regular business day the Transfer Agent receives an exchange request in
proper form (the "Redemption Date"). Normally, shares of the fund to be acquired
are purchased on the Redemption Date, but such purchases may be delayed by
either fund up to five business days if it determines that it would be
disadvantaged by an immediate transfer of the redemption proceeds. The Fund
reserves the right, in its discretion, to refuse any exchange request that may
disadvantage it. For example, if the receipt of multiple exchange requests from
a dealer might require the disposition of portfolio securities at a time or at a
price that might be disadvantageous to the Fund, the Fund may refuse the
request.

In connection with any exchange request, the number of shares exchanged
may be less than the number requested if the exchange or the number requested
would include shares subject to a restriction cited in the Prospectus or this
Statement of Additional Information, or would include shares covered by a share
certificate that is not tendered with the request. In those cases, only the
shares available for exchange without restriction will be exchanged.

The different Oppenheimer funds available for exchange have different
investment objectives, policies and risks. A shareholder should assure that the
fund selected is appropriate for his or her investment and should be aware of
the tax consequences of an exchange. For federal income tax purposes, an
exchange transaction is treated as a redemption of shares of one fund and a
purchase of shares of another. "Reinvestment Privilege," above, discusses some
of the tax consequences of reinvestment of redemption proceeds in such cases.
The Fund, the Distributor, and the Transfer Agent are unable to provide
investment, tax or legal advice to a shareholder in connection with an exchange
request or any other investment transaction.

Dividends, Capital Gains and Taxes

Dividends and Distributions. Dividends will be payable on shares held of record
at the time of the previous determination of net asset value, or as otherwise
described in "How to Buy Shares." Daily dividends will not be declared or paid
on newly purchased shares until such time as Federal Funds (funds credited to a
member bank's account at the Federal Reserve Bank) are available from the
purchase payment for such shares. Normally, purchase checks received from
investors are converted to Federal Funds on the next business day. Shares
purchased through dealers or brokers normally are paid for by the third business
day following the placement of the purchase order.

Shares redeemed through the regular redemption procedure will be paid
dividends through and including the day on which the redemption request is
received by the Transfer Agent in proper form. Dividends will be declared on
shares repurchased by a dealer or broker for three business days following the
trade date (that is, up to and including the day prior to settlement of the
repurchase). If all shares in an account are redeemed, all dividends accrued on
shares of the same class in the account will be paid together with the
redemption proceeds.

The Fund's practice of attempting to pay dividends on Class A shares at a
constant level requires the Manager to monitor the Fund's portfolio and, if
necessary, to select higher-yielding securities when it is deemed appropriate to
seek income at the level needed to meet the target. Those securities must be
within the Fund's investment parameters, however. The Fund expects to pay
dividends at a targeted level from its net investment income and other
distributable income without any impact on the net asset values per share.

The amount of a distribution paid on a class of shares may vary from time
to time depending on market conditions, the composition of the Fund's portfolio,
and expenses borne by the Fund or borne separately by a class. Dividends are
calculated in the same manner, at the same time and on the same day for shares
of each class. However, dividends on Class B and Class C shares are expected to
be lower than dividends on Class A shares. That is due to the effect of the
asset-based sales charge on Class B and Class C shares. Those dividends will
also differ in amount as a consequence of any difference in net asset value
among Class A, Class B and Class C shares.

Dividends, distributions and the proceeds of the redemption of Fund shares
represented by checks returned to the Transfer Agent by the Postal Service as
undeliverable will be invested in shares of Oppenheimer Money Market Fund, Inc.
Reinvestment will be made as promptly as possible after the return of such
checks to the Transfer Agent, to enable the investor to earn a return on
otherwise idle funds. Unclaimed accounts may be subject to state escheatment
laws, and the Fund and the Transfer Agent will not be liable to shareholders or
their representatives for compliance with those laws in good faith.

Tax Status of the Fund's Dividends and Distributions. The Fund intends to
qualify under the Internal Revenue Code during each fiscal year to pay
"exempt-interest dividends" to its shareholders. Exempt-interest dividends that
are derived from net investment income earned by the Fund on municipal
securities will be excludable from gross income of shareholders for Federal
income tax purposes.

A portion of the exempt-interest dividends paid by the Fund may be an item
of tax preference for shareholders subject to the alternative minimum tax. The
amount of any dividends attributable to tax preference items for purposes of the
alternative minimum tax will be identified when tax information is distributed
by the Fund.

A shareholder receiving a dividend from income earned by the Fund from one
or more of the following sources treats the dividend as a receipt of either
ordinary income or long-term capital gain in the computation of gross income,
regardless of whether the dividend is reinvested: (1) certain taxable temporary
investments (such as certificates of deposit,
repurchase agreements, commercial paper and obligations of the U.S.
government, its agencies and instrumentalities);
(2) income from securities loans; (3) income or gains from options or futures;
or (4) an excess of net short-term capital gain over net long-term capital loss
from the Fund.

The Fund's dividends will not be eligible for the dividends-received
deduction for corporations. Shareholders receiving Social Security benefits
should be aware that exempt-interest dividends are a factor in determining
whether such benefits are subject to Federal income tax. Losses realized by
shareholders on the redemption of Fund shares within six months of purchase
(which period may be shortened by regulation) will be disallowed for Federal
income tax purposes to the extent of exempt-interest dividends received on such
shares.

Shares of the Fund will be exempt from Pennsylvania county personal
property taxes to the extent that on the annual assessment date the Fund's
portfolio securities consist of :
|_| Pennsylvania municipal securities,
|_| obligations of the U.S. government (and certain of its territories,
agencies and instrumentalities), and
|_| certain other obligations that are not subject to such personal property
taxes.

To the extent that distributions paid by the Fund are derived from
interest on Pennsylvania municipal securities, qualifying obligations of the
U.S. government and certain U.S. territories, agencies and instrumentalities,
those distributions will also be exempt from Pennsylvania personal income tax,
and in the case of residents of Philadelphia, exempt from the investment income
tax of the School District of Philadelphia. Distributions from the Fund
attributable to income from sources other than those will generally be subject
to Pennsylvania personal income tax.

Corporations that are subject to the Pennsylvania corporate net income tax
will not be subject to tax on distributions received from the Fund provided that
such distributions are not included in federal taxable income determined before
net operating loss deductions and special deductions. As a result of a
pronouncement by the Pennsylvania Department of Revenue, an investment in the
Fund by a corporate shareholder will apparently qualify as an exempt asset for
purposes of the single asset apportionment fraction available in computing the
Pennsylvania capital stock/foreign franchise tax to the extent that the Fund's
portfolio securities comprise investments in Pennsylvania and/or U.S. government
securities that would be exempt assets if owned directly by the corporation.

Under the Internal Revenue Code, by December 31 each year the Fund must
distribute 98% of its taxable investment income earned from January 1 through
December 31 of that year and 98% of its capital gains realized in the period
from November 1 of the prior year through October 31 of the current year. If it
does not, the Fund must pay an excise tax on the amounts not distributed. It is
presently anticipated that the Fund will meet those requirements. However, the
Fund's Board of Trustees and the Manager might determine in a particular year
that it would be in the best interest of shareholders not to make distributions
at the required levels and to pay the excise tax on the undistributed amounts.
That would reduce the amount of income or capital gains available for
distribution to shareholders.

Dividend Reinvestment in Another Fund. Shareholders of the Fund may elect to
reinvest all dividends and/or capital gains distributions in shares of the same
class of any of the other Oppenheimer funds listed above. Reinvestment will be
made at net asset value without sales charge. To elect this option, the
shareholder must notify the Transfer Agent in writing and must have an existing
account in the fund selected for reinvestment. Otherwise the shareholder must
first obtain a prospectus for that fund and an application from the Transfer
Agent to establish an account. The investment will be made at the net asset
value per share in effect at the close of business on the payable date of the
dividend or distribution. Dividends and/or distributions from certain of the
other Oppenheimer funds may be invested in shares of this Fund on the same
basis.

Additional Information About the Fund

The Transfer Agent. The Fund's Transfer Agent, OppenheimerFunds Services, is a
division of the Manager. It is responsible for maintaining the Fund's
shareholder registry and shareholder accounting records, and for paying
dividends and distributions to shareholders of the Fund. It also handles
shareholder servicing and administrative functions. It is paid on an "at-cost"
basis.

The Custodian. Citibank, N.A. is the Custodian of the Fund's assets. The
Custodian's responsibilities include safeguarding and controlling the Fund's
portfolio securities, and handling the delivery of such securities to and from
the Fund. It will be the practice of the Fund to deal with the Custodian in a
manner uninfluenced by any banking relationship the Custodian may have with the
Manager and its affiliates. The Fund's cash balances with the Custodian in
excess of $100,000 are not protected by Federal Deposit Insurance. Those
uninsured balances may at times be substantial.

Independent Auditors. KPMG Peat Marwick LLP are the independent auditors of the
Fund. They audit the Fund's financial statements and perform other related audit
services. They also act as auditors for certain other funds advised by the
Manager and its affiliates.

================================================================================
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.

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.

25 Oppenheimer Pennsylvania Municipal Fund
<PAGE>

- --------------------------------------------------------------------------------
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.

- --------------------------------------------------------------------------------
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.

- --------------------------------------------------------------------------------
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.

- --------------------------------------------------------------------------------
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.

Descriptions of Municipal Bond Ratings Categories
- -------------------------------------------------------------------------------
- -------------------------------------------------------------------------------
Of Principal Rating Agencies
- -------------------------------------------------------------------------------

Municipal Bonds

Moody's Investor Services, Inc. The ratings of Moody's Investors Service, Inc.
("Moody's") for municipal bonds are Aaa, Aa, A, Baa, Ba, B, Caa, Ca and C. Those
bonds in the Aa, A, Baa, Ba and B groups which Moody's believes possess the
strongest investment attributes are designated Aa1, A1, Baa1, Ba1 and B1
respectively.

|_| Aaa. Municipal bonds rated "Aaa" are judged to be of the "best quality." |_|
Aa. The rating "Aa" is assigned to bonds which are judged of "high quality by
all standards," but as to which margins of protection or other elements make
long-term risks appear somewhat larger than "Aaa" rated municipal bonds. "Aaa"
and "Aa" rated bonds are generally known as "high grade bonds." |_| A. Municipal
bonds rated "A" by Moody's possess many favorable investment attributes and are
considered "upper medium grade obligations." Factors giving security to
principal and interest of A rated bonds are considered adequate, but elements
may be present which suggest a susceptibility to impairment at some time in the
future. |_| Baa. Municipal bonds rated "Baa" are considered "medium grade"
obligations. They are neither highly protected nor poorly secured. Interest
payments and principal security appear adequate for the present but certain
protective elements may be lacking or may be characteristically unreliable over
any great length of time. These bonds lack outstanding investment
characteristics and have speculative characteristics as well. |_| Ba. Bonds
rated "Ba" are judged to have speculative elements. Their future cannot be
considered as well assured. Often the protection of interest and principal
payments may be very moderate and thereby not well safeguarded during both good
and bad times over the future. Uncertainty of position characterizes bonds in
this class. |_| B. Bonds rated "B" generally lack characteristics of the
desirable investment. Assurance of interest and principal payments or of
maintenance of other terms of the contract over any long period of time may be
small. |_| Caa. Bonds rated "Caa" are in poor standing. Such issues may be in
default or there may be present elements of danger with respect to principal or
interest. |_| Ca. Bonds rated "Ca" represent obligations which are speculative
in a high degree. Such issues are often in default or have other marked
shortcomings. |_| C. Bonds rated "C" are the lowest rated class of bonds. Issues
so rated can be regarded as having extremely poor prospects of ever attaining
any real investment standing.

Municipal bonds rated by Moody's that have a demand feature that provides
the holder with the ability to periodically tender ("put") the portion of the
debt covered by the demand feature, may also have a short-term rating assigned
to such demand feature. The short-term rating uses the symbol "VMIG" to
distinguish characteristics that include payment upon periodic demand rather
than fund or scheduled maturity dates and potential reliance upon external
liquidity, as well as other factors. The highest investment quality is
designated by the VMIG 1 rating and the lowest by VMIG 4.

Standard & Poor's Corporation. Bonds rated in the top four categories (AAA, AA,
A, BBB) are commonly referred to as "investment grade." The ratings from AA to
CCC may be modified by the addition of a plus or minus sign to show relative
standing within the major rating categories. Ratings of BB, B, CCC and CC are
regarded as having significant speculative characteristics.

|_| AAA. Obligors of municipal bonds rated AAA have "extremely strong capacity"
to meet financial commitments. |_| AA. The rating AA is given to obligors with
"very strong capacity" to meet financial commitments. |_| A. The rating A is
given to obligors with a "strong capacity" to meet financial commitments but is
somewhat more susceptible to adverse effects of changes in circumstances and
economic conditions than obligors in higher categories. |_| BBB. The BBB rating
is given to an obligor that has "adequate capacity" to meet its financial
commitments. However, adverse economic conditions or changing circumstances are
more likely to lead to a weakened capacity of the obligor to meet its financial
commitments. |_| BB. Obligors rated BB are less vulnerable in the near-term than
other lower-rated obligations to default than other speculative issues. However,
they face major ongoing uncertainties or exposure to adverse business,
financial, or economic conditions which would lead to inadequate capacity to
meet financial commitments. |_| B. Obligors rated B have a greater vulnerability
than obligors rated BB, but currently has the capacity to meet its financial
commitments. Adverse business, financial, or economic conditions will likely
impair the obligor's capacity or willingness to meet its financial commitments.
|_| CCC. Obligors rated CCC are currently vulnerable and are dependent upon
favorable business, financial, and economic conditions to meet financial
commitments. |_| CC. Obligors rated CC are currently highly vulnerable. |_| C.
Bonds rated C typically are debt subordinated to senior debt that is assigned an
actual or implied CCC- debt rating. The C rating may be used to cover a
situation where a bankruptcy petition has been filed, but debt service payments
are continued. |_| D. Bonds rated D are in payment default. The D rating
category is used when interest payments or principal payments are not made on
the date due even if the applicable grace period has not expired, unless S&P
believes that such payments will be made during the grace period. The D rating
also will be used upon the filing of a bankruptcy petition if debt service
payments are jeopardized. Fitch. The ratings of Fitch IBCA, Inc. for municipal
bonds are AAA, AA, A, BBB, BB, B, CCC, CC, C, DDD, DD, and D. Bonds rated AAA,
AA, A and BBB are considered to be of investment grade quality. Bonds rated
below BBB are considered to be of speculative quality. |_| AAA. Municipal Bonds
rated AAA are judged to be of the "highest credit quality." |_| AA. The rating
of AA is assigned to bonds of "very high credit quality." |_| A. Municipal bonds
rated A are considered to be of "high credit quality." |_| BBB. The rating BBB
is assigned to bonds of "satisfactory credit quality." A and BBB rated bonds are
more vulnerable to adverse changes in economic conditions than bonds with higher
ratings. |_| BB. The rating BB is assigned to bonds considered to be
"speculative." |_| B. The rating B is assigned to bonds considered to be "highly
speculative." |_| CCC. Bonds rated CCC have certain identifiable characteristics
which, if not remedied, may lead to default. |_| CC. Bonds rated CC are
considered minimally protected. Default in payment of interest and/or principal
seems probable over time. |_| C. Bonds rated C are in imminent default in
payment of interest or principal. |_| DDD and below. Bonds rated DDD, DD and D
are in default on interest and/or principal payments. DDD represents the highest
potential for recovery on these bonds, and D represents the lowest potential for
recovery.

Duff & Phelps. The ratings of Duff & Phelps are as follows:
|_| AAA. These are judged to be the "highest credit quality". The risk
factors are negligible, being only slightly more than for risk-free U.S.
Treasury debt.
|_| AA+, AA & AA-. High credit quality. Protection factors are strong. Risk is
modest but may vary slightly from time to time because of economic conditions.
|_| A+, A & A-. Protection factors are average but adequate. However, risk
factors are more variable and greater in periods of economic stress. |_| BBB+,
BBB & BBB-. These have below average protection factors but are still considered
sufficient for prudent investment. They have considerable variability in risk
during economic cycles. |_| BB+, BB & BB-. These are below investment grade but
are deemed to be able to meet obligations when due. Present or prospective
financial protection factors fluctuate according to industry conditions or
company fortunes. Overall quality may move up or down frequently within the
category. |_| B+, B & B-. These are below investment grade and possess risk that
obligations will not be met when due. Financial protection factors will
fluctuate widely according to economic cycles, industry conditions and/or
company fortunes. Potential exists for frequent changes in the rating within
this category or into a higher of lower rating grade. |_| CCC. Well below
investment grade securities. Considerable uncertainty exists as to timely
payment of principal interest or preferred dividends. Protection factors are
narrow and risk can be substantial with unfavorable economic industry
conditions, and/or with unfavorable company developments. |_| DD. These are
defaulted debt obligations. The issuer failed to meet scheduled principal and/or
interest payments.

Municipal Notes

Moody's. Moody's ratings for state and municipal notes and other short-term
loans are designated Moody's Investment Grade ("MIG"). Notes bearing the
designation MIG-1 are of the best quality, enjoying strong protection from
established cash flows of funds for their servicing or from established and
broad-based access to the market for financing. Notes bearing the designation
"MIG-2" are of high quality with ample margins of protection, although not as
large as notes rated "MIG-1." Such short-term notes that have demand features
may also carry a rating using the symbol VMIG as described above, with the
designation MIG-1/VMIG 1 denoting best quality, with superior liquidity support
in addition to those characteristics attributable to the designation MIG-1.

Standard & Poor's. S&P's ratings for municipal notes due in three years or less
are SP-1, SP-2, and SP-3. SP-1 describes issues with a very strong capacity to
pay principal and interest and compares with bonds rated A by S&P. If modified
by a plus sign, it compares with bonds rated AA or AAA by S&P. SP-2 describes
issues with a satisfactory capacity to pay principal and interest, and compares
with bonds rated BBB by S&P. SP-3 describes issues that have a speculative
capacity to pay principal and interest.

Fitch. Fitch's rating for municipal notes due in three years or less are F-1+,
F-1, F-2, F-3, F-S and D. F-1+ describes notes with an exceptionally strong
credit quality and the strongest degree of assurance for timely payment. F-1
describes notes with a very strong credit quality and assurance of timely
payment is only slightly less in degree than issues rated F-1+. F-2 describes
notes with a good credit quality and a satisfactory assurance of timely payment,
but the margin of safety is not as great for issues assigned F-1+ or F-1
ratings. F-3 describes notes with a fair credit quality and an adequate
assurance of timely payment, but near-term adverse changes could cause such
securities to be rated below investment grade. F-S describes notes with weak
credit quality. Issues rated D are in actual or imminent payment default.

Corporate Debt

The other debt securities included in the definition of temporary
defensive investments the Fund may hold are corporate (as opposed to
municipal) debt obligations. The Moody's, S&P and Fitch corporate debt
ratings do not differ materially from those set forth above for municipal
bonds.
Commercial Paper

Moody's. The ratings of commercial paper by Moody's are Prime-1, Prime-2,
Prime-3 and Not Prime. Issuers rated Prime-1 have a superior capacity for
repayment of short-term promissory obligations. Issuers rated Prime-2 have a
strong capacity for repayment of short-term promissory obligations. Issuers
rated Prime-3 have an acceptable capacity for repayment of short-term promissory
obligations. Issuers rated Not Prime do not fall within any of the Prime rating
categories.

S&P. The ratings of commercial paper by S&P are A-1, A-2, A-3, B, C, and D. A-1
indicates that the degree of safety regarding timely payment is strong. A-2
indicates capacity for timely payment is satisfactory. However, the relative
degree of safety is not as high as for issues designated A-1. A-3 indicates an
adequate capacity for timely payments. These issues are, however, more
vulnerable to the adverse effects of changes in circumstances than obligations
carrying the higher designations. B indicates only speculative capacity for
timely payment. C indicates a doubtful capacity for payment. D is assigned to
issues in default.

Fitch. The ratings of commercial paper by Fitch are similar to its ratings
of Municipal Notes, above.

OppenheimerFunds Special Sales Charge Arrangements and Waivers
- -------------------------------------------------------------------------------

In certain cases, the initial sales charge that applies to purchases of
Class A shares of the Oppenheimer funds or the contingent deferred sales charge
that may apply to Class A, Class B or Class C shares may be waived. That is
because of the economies of sales efforts realized by the Distributor or the
dealers or other financial institutions offering those shares to certain classes
of investors or in certain transactions.

Not all waivers apply to all funds. For example, waivers relating to
Retirement Plans do not apply to Oppenheimer municipal funds, because shares of
those funds are not available for purchase by or on behalf of retirement plans.
Other waivers apply only to shareholders of certain funds that were merged into
or became Oppenheimer funds.

For the purposes of some of the waivers described below and in the
Prospectus and Statement of Additional Information of the applicable Oppenheimer
funds, the term "Retirement Plan" refers to the following types of plans: (1)
plans qualified under Sections 401(a) or 401(k) of the Internal Revenue
Code,
(2) non-qualified deferred compensation plans, (3) employee benefit plans1 (4)
Group Retirement Plans2 (5) 403(b)(7) custodial plan accounts (6) SEP-IRAs,
SARSEPs or SIMPLE plans

The interpretation of these provisions as to the applicability of a waiver
in a particular case is determined solely by the Distributor or the Transfer
Agent of the fund. These waivers and special arrangements may be amended or
terminated at any time by the applicable Fund and/or the Distributor. Waivers
that apply at the time shares are redeemed must be requested by the shareholder
and/or dealer in the redemption request.
- --------------
1. An "employee benefit plan" means any plan or arrangement, whether or not it
is "qualified" under the Internal Revenue Code, under which Class A shares of
an Oppenheimer fund or funds are purchased by a fiduciary or other
administrator for the account of participants who are employees of a single
employer or of affiliated employers. These may include, for example, medical
savings accounts, payroll deduction plans or similar plans. The fund accounts
must be registered in the name of the fiduciary or administrator purchasing
the shares for the benefit of participants in the plan.
2. The term "Group Retirement Plan" means any qualified or non-qualified
retirement plan for employees of a corporation or sole proprietorship,
members and employees of a partnership or association or other organized
group of persons (the members of which may include other groups), if the
group has made special arrangements with the Distributor and all members of
the group participating in (or who are eligible to participate in) the plan
purchase Class A shares of an Oppenheimer fund or funds through a single
investment dealer, broker or other financial institution designated by the
group. Such plans include 457 plans, SEP-IRAs, SARSEPs, SIMPLE plans and
403(b) plans other than plans for public school employees. The term "Group
Retirement Plan" also includes qualified retirement plans and non-qualified
deferred compensation plans and IRAs that purchase Class A shares of an
Oppenheimer fund or funds through a single investment dealer, broker or other
financial institution that has made special arrangements with the Distributor
enabling those plans to purchase Class A shares at net asset value but
subject to the Class A contingent deferred sales charge.

<PAGE>

- -------------------------------------------------------------------------------
Applicability of Class A Contingent Deferred Sales Charges in Certain Cases
- -------------------------------------------------------------------------------

Purchases of Class A Shares of Oppenheimer Funds That Are Not Subject to Initial
Sales Charge but May Be Subject to the Class A Contingent Deferred Sales Charge
(unless a waiver applies).

There is no initial sales charge on purchases of Class A shares of any of
the Oppenheimer funds in the cases listed below. However, these purchases may be
subject to the Class A contingent deferred sales charge if redeemed within 18
months of the end of the calendar month of their purchase, as described in the
Prospectus (unless a waiver described elsewhere in this Appendix applies to the
redemption). Additionally, on these purchases the Distributor will pay the
applicable commission described in the Prospectus under "Class A Contingent
Deferred Sales Charge": |_| Purchases of Class A shares aggregating $1 million
or more. |_| Purchases by a Retirement Plan that: (1) buys shares costing
$500,000 or more, or (2) has, at the time of purchase, 100 or more eligible
participants or total
plan assets of $500,000 or more, or
(3) certifies to the Distributor that it projects to have annual plan
purchases of $200,000 or more.
|_| Purchases by an OppenheimerFunds-sponsored Rollover IRA, if the
purchases are made:
(1) through a broker, dealer, bank or registered investment adviser that
has made special arrangements with the Distributor for those
purchases, or
(2) by a direct rollover of a distribution from a qualified Retirement
Plan if the administrator of that Plan has made special arrangements
with the Distributor for those purchases.
|_| Purchases of Class A shares by Retirement Plans that have any of the
following record-keeping arrangements:
(1) The record keeping is performed by Merrill Lynch Pierce Fenner & Smith,
Inc. ("Merrill Lynch") on a daily valuation basis for the
Retirement Plan. On the date the plan sponsor signs the
record-keeping service agreement with Merrill Lynch, the Plan must
have $3 million or more of its assets invested in (a) mutual funds,
other than those advised or managed by Merrill Lynch Asset
Management, L.P. ("MLAM"), that are made available under a Service
Agreement between Merrill Lynch and the mutual fund's principal
underwriter or distributor, and (b) funds advised or managed by
MLAM (the funds described in (a) and (b) are referred to as
"Applicable Investments").
(2) The record keeping for the Retirement Plan is performed on a daily
valuation basis by a record keeper whose services are provided
under a contract or arrangement between the Retirement Plan and
Merrill Lynch. On the date the plan sponsor signs the record
keeping service agreement with Merrill Lynch, the Plan must have $3
million or more of its assets (excluding assets invested in money
market funds) invested in Applicable Investments.
(3) The record keeping for a Retirement Plan is handled under a service
agreement with Merrill Lynch and on the date the plan sponsor signs
that agreement, the Plan has 500 or more eligible employees (as
determined by the Merrill Lynch plan conversion manager).

? A qualified Retirement Plan that had agreed with the former Quest for
Value Advisors to purchase shares of any of the Former Quest for Value Funds at

purchases commenced by December 31, 1996.

Waivers of Initial and Contingent Deferred Sales Charges in Certain
Transactions.

Class A shares issued or purchased in the following transactions are not subject
to sales charges (and no commissions are paid by the Distributor on such

|_| Shares purchased and paid for with the proceeds of shares redeemed in
the prior 30 days from a mutual fund (other than a fund managed by the Manager
or any of its subsidiaries) on which an initial sales charge or contingent
deferred sales charge was paid. This waiver also applies to shares purchased by

to no more than 12% of the original account value.
|_| Involuntary redemptions of shares by operation of law or involuntary
redemptions of small accounts (see "Shareholder Account Rules and Policies," in
the Prospectus).
? For distributions from Retirement Plans, deferred compensation plans

Prior Class A CDSC and Class A Sales Charge Waivers

? Class A Contingent Deferred Sales Charge. Certain shareholders of a Fund
and the other Former Connecticut Mutual Funds are entitled to continue to make
additional purchases of Class A shares at net asset value without a Class A

charge that was in effect prior to March 18, 1996 (the "prior Class A CDSC").
Under the prior Class A CDSC, if any of those shares are redeemed within one
year of purchase, they will be assessed a 1% contingent deferred sales charge on
an amount equal to the current market value or the original purchase price of
the shares sold, whichever is smaller (in such redemptions, any shares not
subject to the prior Class A CDSC will be redeemed first).

Those shareholders who are eligible for the prior Class A CDSC are: (1)
persons whose purchases of Class A shares of a Fund and other Former
Connecticut Mutual Funds were $500,000 prior to March 18, 1996, as a

Former Connecticut Mutual Funds to purchase shares valued at $500,000 or
more over a 13-month period entitled those persons to purchase shares at
net asset value without being subject to the Class A initial sales
charge.

Any of the Class A shares of a Fund and the other Former Connecticut
Mutual Funds that were purchased at net asset value prior to March 18, 1996,
remain subject to the prior Class A CDSC, or if any additional shares are
purchased by those shareholders at net asset value pursuant to this arrangement
they will be subject to the prior Class A CDSC.

? Class A Sales Charge Waivers. Additional Class A shares of a Fund may be
purchased without a sales charge, by a person who was in one (or more) of the
categories below and acquired Class A shares prior to March 18, 1996, and still
holds Class A shares: (1) any purchaser, provided the total initial amount
invested in the Fund or
any one or more of the Former Connecticut Mutual Funds totaled $500,000
or more, including investments made pursuant to the Combined Purchases,
Statement of Intention and Rights of Accumulation features available at
the time of the initial purchase and such investment is still held in
one or more of the Former Connecticut Mutual Funds or a Fund into which
such Fund merged;
(2) any participant in a qualified plan, provided that the total initial
amount invested by the plan in the Fund or any one or more of the Former
Connecticut Mutual Funds totaled $500,000 or more;
(3) Directors of the Fund or any one or more of the Former Connecticut
Mutual Funds and members of their immediate families;

individuals, if such institution was directly compensated by the
individual(s) for recommending the purchase of the shares of the Fund or
any one or more of the Former Connecticut Mutual Funds, provided the
institution had an agreement with CMFS.

Purchases of Class A shares made pursuant to (1) and (2) above may be
subject to the Class A CDSC of the Former Connecticut Mutual Funds described
above.

Additionally, Class A shares of a Fund may be purchased without a sales
charge by any holder of a variable annuity contract issued in New York State by
Connecticut Mutual Life Insurance Company through the Panorama Separate Account

fund a qualified plan, if that holder exchanges the variable annuity contract
proceeds to buy Class A shares of the Fund.

In addition to the waivers set forth in the Prospectus and in this Appendix,
above, the contingent deferred sales charge will be waived for redemptions of
Class A and Class B shares of a Fund and exchanges of Class A or Class B shares
of a Fund into Class A or Class B shares of a Former Connecticut Mutual Fund

The Fund's Objective and Investment Strategies

- -------------------------------------------------------------------------------
What Is the Fund's Investment Objective? The Fund's investment objective is
to seek as high a level of current interest income exempt from federal and
New Jersey income taxes for individual investors as is consistent with
preservation of capital.
- -------------------------------------------------------------------------------

What Does the Fund Invest In? The Fund invests mainly in New Jersey municipal
securities that pay interest exempt from federal and New Jersey individual
income taxes. These primarily include municipal bonds (which are long-term
obligations), municipal notes (short-term obligations), interests in municipal
leases, and tax-exempt commercial paper. Most of the securities the Fund buys
must be "investment grade" (the four highest rating categories of national
rating organizations, such as Moody's).

|X| How Does the Manager Decide What Securities to Buy or Sell? In
selecting securities for the Fund, the Manager currently looks primarily
throughout New Jersey for municipal securities using a variety of factors which
may change over time and may vary in particular cases:
|_| Securities that provide high income
|_| The goal of spreading risk among a wide range of securities of
different issuers within the state, including different agencies and
municipalities |_| Issues with favorable credit characteristics |_|
Special situations among issuers that provide opportunities for value

Who Is the Fund Designed For? The Fund is designed for investors who are seeking
income exempt from federal and New Jersey income taxes. It does not seek capital
gains or growth. Because it invests in tax-exempt securities, the Fund is not
appropriate for retirement plan accounts or for investors who want to pursue
capital growth.

Main Risks of Investing in the Fund

How Risky Is the Fund Overall? The value of the Fund's investments in municipal
securities will change over time due to a number of factors. They include
changes in general bond market movements, the change in value of particular
bonds because of an event affecting the issuer, or changes in interest rates
that can affect bond prices overall. The Fund focuses its investments in New
Jersey municipal securities and is non-diversified. It will therefore be
vulnerable to the effects of economic changes that affect New Jersey
governmental issuers. These changes can affect the value of the Fund's
investments and its price per share. The Fund may invest in derivative
investments. These have additional risks and can cause fluctuations in the
Fund's share prices. In the OppenheimerFunds spectrum, the Fund is more
conservative than some types of taxable bond funds, such as high yield bond
funds, but more aggressive than money market funds.

An investment in the Fund is not a deposit of any bank, and is not insured
or guaranteed by the Federal Deposit Insurance Corporation or any other
government agency.

|X| Risks of Non-Diversification -- Investments in New Jersey Municipal
Securities. The Fund is "non-diversified." That means that compared to funds
that are diversified, it can invest a greater portion of its assets in the
securities of one issuer, such as bonds issued by the State of New Jersey.
Having a higher percentage of its assets invested in the securities of fewer
issuers, particularly government issuers of a single state, could result in
greater fluctuations of the Fund's share prices due to economic, regulatory or
political problems in New Jersey.

The Fund's Past Performance

The bar chart and table below show one measure of the risks of investing in the
Fund, by showing changes in the Fund's performance (for its Class A shares) from
year to year for the calendar years since the Fund's inception (3/1/94) and by
showing how the average annual total returns of the Fund's shares compare to
those of a broad-based market index. The Fund's past investment performance is
not necessarily an indication of how the Fund will perform in the future.

[See bar chart in Appendix]

For the period from 1/1/98 through 9/30/98, the cumulative return (not
annualized) for Class A shares was 5.94%. Sales charges are not included in the
calculations of return in this bar chart, and if those charges were included,
the returns would be less than those shown. During the period shown in the bar
chart, the highest return (not annualized) for a calendar quarter was 6.81%
(1Q'95) and the lowest return for a calendar quarter was 0.03% (1Q'96).

* Inception dates of classes: Class A: 3/1/94; Class B: 3/1/94; Class C:
8/29/95. The index performance is shown from 2/28/94.

The Fund's average annual total returns in the table include the applicable
sales charge: for Class A, the current maximum initial sales charge of 4.75%;
for Class B, the applicable contingent deferred sales charges of 5% (1-year) and
3% (life of class); for Class C, the 1% contingent deferred sales charge for the
1-year period.

The returns measure the performance of a hypothetical account and assume that
all dividends and capital gains distributions have been reinvested in additional
shares. Because the Fund invests in municipal securities, the Fund's performance
is compared to the Lehman Brothers Municipal Bond Index, an unmanaged index of a
broad range of investment grade municipal bonds that is a measure of the
performance of the general municipal bond market. However, it must be remembered
that the index includes municipal securities from many states while the Fund
focuses on New Jersey municipal securities, and the index performance does not
consider the effects of capital gains or transaction costs.

Numbers in the table are based on the Fund's expenses in the last fiscal year,
ended 7/31/98. However, the management fees shown are the amounts that would
have been paid by the Fund if the Manager had not absorbed some expenses under
its voluntary expense undertaking to the Fund. After the Manager's waiver, the
Fund paid no management fees for the fiscal year. The Manager can withdraw that
voluntary waiver at any time. Expenses may vary in future years. "Other
expenses" include transfer agent fees, custodial fees, and accounting and legal
expenses the Fund pays.

Examples. These examples are intended to help you compare the cost of
investing in the Fund with the cost of investing in other mutual funds.

About the Fund's Investments

The Fund's Principal Investment Policies. The Fund's goal is to seek as high a
level of current interest income that is exempt from federal and New Jersey
income taxes for individual investors as is available from municipal securities,
consistent with preservation of capital. Under normal market conditions, the
Fund:
|_| attempts to invest 100% of its assets in municipal securities, |_| as
a fundamental policy, attempts to invest at least 80% of its assets in
municipal securities, and |_| invests at least 80% of its total assets in
New Jersey municipal
securities.

The Statement of Additional Information contains more detailed information
about the Fund's investment policies and risks.

New Jersey municipal securities, on which the Fund focuses its
investments, are municipal securities that are not subject (at the time they are
issued) to New Jersey individual income tax, in the opinion of bond counsel to
the issuer. These debt obligations are issued by the State of New Jersey and its
political subdivisions (such as cities, towns, counties, agencies and
authorities). They also may include debt obligations of the governments of
certain possessions, territories and commonwealths of the United States if the
interest is not subject to New Jersey individual income tax.

The Fund may also buy other municipal securities, issued by the
governments of the District of Columbia and of other states, as well as their
political subdivisions, authorities and agencies, and securities issued by any
commonwealths, territories or possessions of the United States, or their
respective agencies, instrumentalities or authorities, if the interest paid on
the security is not subject to federal individual income tax (in the opinion of
bond counsel to the issuer at the time the security is issued).

|_| Special Credit Risks of Lower-Grade Securities. Lower-grade municipal
securities may be subject to greater market fluctuations and greater risks of
loss of income and principal than higher-rated municipal securities. Securities
that are (or that have fallen) below investment grade entail a greater risk that
the issuers of such securities may not meet their debt obligations. However, by
limiting its investments in non-investment grade municipal securities to not
more than 25% of its assets, the Fund may reduce the effect of some of these
risks on its share price and income.

Other Investment Strategies. To seek its objective, the Fund can also use the
investment techniques and strategies described below. These techniques involve
certain risks or are designed to help reduce some of the risks.

Temporary Defensive Investments. The Fund may invest up to 100% of its total
assets in temporary defensive investments from time to time. This may happen
during periods of unusual market conditions. Generally, they would be short-term
municipal securities but could be U.S. government securities or highly-rated
corporate debt securities. The income from some of those temporary defensive
investments may not be tax-exempt, and therefore when making those investments
the Fund may not achieve its objective. The Fund may also hold these types of
temporary investments pending the investment of proceeds from the sale of Fund
shares or portfolio securities, or to meet anticipated redemptions of Fund
shares.

How the Fund is Managed

|X| Portfolio Manager. The Portfolio manager of the Fund is Caryn
Halbrecht, a Vice President of the Manager. Ms. Halbrecht is the person
principally responsible for the day-to-day management of the Fund's
portfolio, and has had this responsibility since July 8, 1996. Ms. Halbrecht
also serves as an officer and portfolio manager for other Oppenheimer funds.
Prior to joining OppenheimerFunds, Ms. Halbrecht was a Vice President of
Fixed Income Portfolio Management at Bankers Trust Company.

|X| Advisory Fees. Under the Investment Advisory Agreement, the Fund pays
the Manager an advisory fee at an annual rate which declines on additional
assets as the Fund grows: 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. As a result of the Manager's
voluntary assumption of certain Fund expenses, the Fund paid no management fee
for its last fiscal year ended July 31, 1998.
