o Oppenheimer World Bond Fund converted from a closed-end fund to an open-end
fund at the close of business on April 24, 1998.

o Developed bond markets in the U.S. and Europe generally performed well, but
the emerging markets declined sharply.

o We are finding compelling values in Latin American bonds, which in our opinion
were unfairly punished in the wake of the Asian crisis.

 Dear shareholder,

Bridget A. Macaskill
President
Oppenheimer
World Bond Fund

As we move further into 1998, we remain impressed by the remarkable resilience
of the financial markets. Recent efforts by the United States to help support
the Japanese Yen have inspired hope that the fallout of the Asian economic
crisis can be contained. In general, the U.S. and world markets have continued
to build wealth for investors at a virtually unprecedented pace.

     At OppenheimerFunds, we are pleased to help our fund shareholders
participate in the potential rewards of today's markets, but we also recognize
that this rate of growth cannot last forever. Because no one can predict exactly
when the next correction or bear market might occur, we think it is prudent to
continually identify, evaluate and manage the risks that may affect our fund
shareholders.

     We believe that one of the leading risks facing investors today is that
stock valuations are at the high end of their historical range, while U.S.
corporate earnings growth is slowing. Given these facts, we believe it is
unlikely that stocks will sustain the growth rate of the past three years. Stock
prices could continue trading near current levels until earnings "catch up," or
there could be a market correction. However, we believe that either scenario
would be only a temporary pause on the way to potentially greater long-term
gains.

     We are also examining the potential economic effects of the "millennium
problem" that may render many computer systems unable to recognize the year 2000
when it arrives. Solving this problem has required companies to divert
substantial human and financial resources from their core businesses, possibly
constraining global economic growth during 1999 and 2000.

     For our part, we can report that OppenheimerFunds has made solid progress
toward ensuring that our shareholder accounting systems are fully "year 2000
compliant," and that all shareholder accounts will make a seamless transition
into the 21st century.

     We encourage you to meet with your financial advisor to discuss how a
possible market correction or the millennium problem may affect your
investments. Together, you can prepare your investment portfolio for the
challenges and opportunities of the new century.

Sincerely,


/s/ Bridget A. Macaskill

The Fund's performance was negatively impacted by the decline in the Asian
markets which occurred in October 1997. Though the Fund had very little exposure
to Asia in general at the time, the Fund's investments in Latin America, Eastern
Europe, Australia, New Zealand, Russia and other emerging markets were
negatively affected by a "spill-over" effect from the Asian crisis. Accordingly,
when the Asian crisis erupted at the start of the six-month reporting period, we
quickly worked to reduce our emerging-markets exposure. As this area began to
recover toward the end of the six-month period, we slowly and selectively
rebuilt our emerging-markets position.

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

"The Fund had very little exposure to Asia."


How has the Fund performed during the period?

Oppenheimer World Bond Fund's Class A shares provided a cumulative total return,
without sales charges, of 2.87% for the six months ended April 30, 1998.(1) We
attribute this weak performance primarily to the effects of the Asian crisis,
which occurred toward the beginning of the six-month period.

International markets experienced sharp declines after the Asian crisis in late
October. What happened?

Although Asian markets sold off sharply between July and November, 1997, the
forces underlying the decline had developed slowly over the past five years.
During that time, so much investment capital flowed into the region that local
businesses began to use the money for speculative purposes, such as building
excess industrial capacity and office buildings.

      Unfortunately, the region's economy failed to support these excesses.
Sales of Asian goods began to slow in 1997 when a stronger U.S. dollar made the
Asia's exports more expensive for consumers in the U.S. and Europe. At the same
time, the Japanese yen weakened, making Japan more competitive relative to other
Asian exporters. As a result, several countries were forced to devalue their
currencies. Many Asian companies, already overextended in the debt markets,
incurred severe losses in foreign exchange markets. When investors attempted to
take their money out of the region, securities prices plunged.

How did the Asian crisis affect the Fund's investments?

We began to avoid Asian securities more than two years ago because we became
wary of the region's speculative use of capital. Consequently, the Fund had very
little exposure to Asia in general, and held no securities issued in the nations
hit hardest by currency devaluations, such as Thailand and Malaysia.

      However, the Fund's investments in Latin America, Eastern Europe,
Australia, New Zealand, Russia and other emerging markets were negatively
affected by a "spillover" effect from the Asian crisis. Accordingly, when the
Asian crisis erupted at the start of the six-month reporting period, we quickly
worked to reduce our emerging-markets exposure. As this area began to recover
toward the end of the six-month period, we slowly and selectively rebuilt our
emerging-markets position.

How did the U.S. bond markets fare?

The U.S. bond market continued to perform quite well. Although U.S. bond prices
fell in the immediate aftermath of the Asian crisis, they quickly rebounded.
That's because the Asian crisis helped cool off the rate of U.S. economic
growth, which calmed inflation fears and produced lower long-term interest
rates. In addition, the Asian crisis caused a "flight to quality," in which
international fixed-income investors shifted their investments away from
emerging-market debt and into developed-market debt. This shift created a surge
in demand for a limited supply of bonds from U.S. issuers, causing their prices
to rise.

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

"Slower economic growth in the U.S. and European markets is expected to help
keep global inflation pressures at bay..."


Within the U.S. bond market, high-yield corporate bonds have experienced a
dramatic rally over the past six months. That's primarily because investors have
chased higher yielding securities in a declining interest-rate environment. This
demand from investors caused the difference in yields between high-yield
corporate bonds and U.S. government securities to narrow to the low end of its
range. Consequently, we took profits in many of our high-yield corporate bond
positions, reducing our high-yield corporate
holdings over the period.

How were the Fund's assets allocated across geographic regions?

As of March 31, 1998, the Fund's assets were allocated 39% to U.S. bonds and 61%
to international bonds. Within the portfolio's international component, 23% was
developed-market debt and approximately 34% was emerging market debt.

The Fund converted from a closed-end fund to an open-end fund. How will this
affect shareholders?

We believe the effect will be positive for shareholders. Prior to conversion,
the Fund traded at a discount to its net asset value. At the time of conversion,
that discount disappeared and shares traded at their net asset value. Existing
shareholders should notice very few changes in the way the Fund is managed. We
intend to employ the same investment strategies that have proven successful
in the past.


                          8 Oppenheimer World Bond Fund
<PAGE>

"...contributing to higher bond prices over the coming months."


What is your outlook for the future?

We are optimistic regarding the global bond markets in 1998, particularly for
U.S. investors. Although domestic interest rates have already declined
substantially over the past year or so, the U.S. bond market appears to continue
to offer higher yields than are available from most comparable European bonds.
If domestic economic growth slows and European economic growth accelerates as we
expect, yields on long-term U.S. bonds could decline further.

      In addition, we are finding very attractive values in the emerging
markets. As more investors realize that non-Asian securities were punished too
severely during last fall's sell-off, their prices could rise substantially. We
are especially bullish about Latin American debt, because compared to Asian
markets, we believe many of Latin America's sovereign issuers have strong
banking systems, manageable fiscal deficits and reasonable borrowing
requirements in the capital markets.

      To prepare for this environment, we have gradually extended our U.S. bond
portfolio's average duration, a measure of sensitivity to changes in interest
rates, to maintain current yields for as long as possible and to take advantage
of opportunities for capital appreciation. Overall, we intend to continue to
manage Oppenheimer World Bond Fund according to the approach that has guided us
since the Fund's inception: investing in a diversified portfolio of bonds issued
primarily by U.S. and foreign governments in emerging and developed markets. We
use intensive analysis to help find fixed-income securities that provide income
advantages. In addition, we attempt to manage the risks of global fixed-income
investing by diversifying the Fund's assets across a broad array of countries
and currencies worldwide. In our view, this approach may continue to provide
high income and growth potential for shareholders.

(3). Interest-Only Strips represent the right to receive the monthly interest
payments on an underlying pool of mortgage loans. These securities typically
decline in price as interest rates decline. Most other fixed income securities
increase in price when interest rates decline. The principal amount of the
underlying pool represents the notional amount on which current interest is
calculated. The price of these securities is typically more sensitive to changes
in prepayment rates than traditional mortgage-backed securities (for example,
GNMA pass-throughs). Interest rates disclosed represent current yields based
upon the current cost basis and estimated timing and amount of future cash
flows.

(4). When-issued security to be delivered and settled after April 30, 1998.

(5). A sufficient amount of securities has been designated to cover outstanding
forward foreign currency exchange contracts. See Note 5 of Notes to Financial
Statements.

(6). Represents the current interest rate for a variable rate security.

(7). Identifies issues considered to be illiquid or restricted--See Note 8 of
Notes to Financial Statements.

(8). Represents securities sold under Rule 144A, which are exempt from
registration under the Securities Act of 1933, as amended. These securities have
been determined to be liquid under guidelines established by the Board of
Trustees. These securities amount to $1,066,327 or 2.08% of the Fund's net
assets as of April 30, 1998.

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

(10). Securities with an aggregate market value of $143,225 are held in
collateralized accounts to cover initial margin requirements on open futures
sales contracts. See Note 6 of Notes to Financial Statements.

(11). Represents the current interest rate for an increasing rate security.

(12). Issuer is in default.

(13). Non-income producing--issuer is in default of interest payment.

(14). Denotes a step bond: a zero coupon bond that converts to a fixed or
variable interest rate at a designated future date.

(15). Interest or dividend is paid-in-kind.

(16). Non-income producing security.

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

Oppenheimer World Bond Fund (the Fund) was initially registered under the
Investment Company Act of 1940, as amended, as a diversified, closed-end
management investment company. Effective April 27, 1998, the Fund began
operating as an open-end fund. The Fund's investment objective is to seek high
current income consistent with preservation of capital through investments in
debt securities. 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. Forward foreign currency contracts are valued based on the
closing prices of the forward currency contract rates in the London foreign
exchange markets on a daily basis as provided by a reliable bank or dealer.
Options are valued based upon the last sale price on the principal exchange on
which the option is traded or, in the absence of any transactions that day, the
value is based upon the last sale price on the prior trading date if it is
within the spread between the closing bid and asked prices. If the last sale
price is outside the spread, the closing bid is used.


                         28 Oppenheimer World Bond Fund
<PAGE>

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

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


================================================================================
Structured Notes. The Fund invests in foreign currency-linked structured notes
whereby the market value and redemption price are linked to foreign currency
exchange rates. The structured notes may be leveraged, which increases the
notes' volatility relative to the face of the security. Fluctuations in values
of the securities are recorded as unrealized gains and losses in the
accompanying financial statements. During the six months ended April 30, 1998,
the market value of these securities comprised an average of 5.27% of the Fund's
net assets, and resulted in realized and unrealized losses of $164,020.

- --------------------------------------------------------------------------------
Securities Purchased on a When-Issued Basis. Delivery and payment for securities
that have been purchased by the Fund on a forward commitment or when-issued
basis can take place a month or more after the transaction date. During this
period, such securities do not earn interest, are subject to market fluctuation
and may increase or decrease in value prior to their delivery. The Fund
maintains, in a segregated account with its custodian, assets with a market
value equal to the amount of its purchase commitments. The purchase of
securities on a when-issued or forward commitment basis may increase the
volatility of the Fund's net asset value to the extent the Fund makes such
purchases while remaining substantially fully invested. As of April 30, 1998,
the Fund had entered into outstanding when-issued or forward commitments of
$4,063,875.

          In connection with its ability to purchase securities on a when-issued
or forward commitment basis, the Fund may enter into mortgage dollar-rolls in
which the Fund sells securities for delivery in the current month and
simultaneously contracts with the same counterparty to repurchase similar (same
type, coupon and maturity) but not identical securities on a specified future
date. The Fund records each dollar-roll as a sale and a new purchase
transaction.

- --------------------------------------------------------------------------------
Security Credit Risk. The Fund invests in high yield securities, which may be
subject to a greater degree of credit risk, greater market fluctuations and risk
of loss of income and principal, and may be more sensitive to economic
conditions than lower yielding, higher rated fixed income securities. The Fund
may acquire securities in default, and is not obligated to dispose of securities
whose issuers subsequently default. At April 30, 1998, securities with an
aggregate market value of $180,161, representing 0.35% of the Fund's net assets,
were in default.

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

Foreign Currency Translation. The accounting records of the Fund are maintained
in U.S. dollars. Prices of securities denominated in foreign currencies are
translated into U.S. dollars at the closing rates of exchange. Amounts related
to the purchase and sale of foreign securities and investment income are
translated at the rates of exchange prevailing on the respective dates of such
transactions.

          The effect of changes in foreign currency exchange rates on
investments is separately identified from the fluctuations arising from changes
in market values of securities held and reported with all other foreign currency
gains and losses in the Fund's Statement of Operations.

- --------------------------------------------------------------------------------
Repurchase Agreements. The Fund requires the custodian to take possession, to
have legally segregated in the Federal Reserve Book Entry System or to have
segregated within the custodian's vault, all securities held as collateral for
repurchase agreements. The market value of the underlying securities is required
to be at least 102% of the resale price at the time of purchase. If the seller
of the agreement defaults and the value of the collateral declines, or if the
seller enters an insolvency proceeding, realization of the value of the
collateral by the Fund may be delayed or limited.

- --------------------------------------------------------------------------------
Federal Taxes. The Fund intends to continue to comply with provisions of the
Internal Revenue Code applicable to regulated investment companies and to
distribute all of its taxable income, including any net realized gain on
investments not offset by loss carryovers, to shareholders. Therefore, no
federal income or excise tax provision is required. At October 31, 1997, the
Fund had available for federal income tax purposes an unused capital loss
carryover of approximately $5,093,000, which expires between 2001 and 2003.

- --------------------------------------------------------------------------------
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 six months
ended April 30, 1998, a provision of $16,470 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 $54,031 at April 30, 1998.

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

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

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


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

- --------------------------------------------------------------------------------
Classification of Distributions to Shareholders. Net investment income (loss)
and net realized gain (loss) may differ for financial statement and tax purposes
primarily because of paydown gains and losses and the recognition of certain
foreign currency gains (losses) as ordinary income (loss) for 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 that 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) and dividend income is recorded on the
ex-dividend date. Discount on securities purchased is amortized over the life of
the respective securities, in accordance with federal income tax requirements.
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. Dividends in kind are recognized as income
on the ex-dividend date, at the current market value of the underlying security.
Interest on payment-in-kind debt instruments is accrued as income at the coupon
rate and a market adjustment is made periodically.

          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 and Administrative 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 0.75% of the first
$200 million of average annual net assets, 0.72% of the next $200 million, 0.69%
of the next $200 million, 0.66% of the next $200 million, 0.60% of the next $200
million and 0.58% of average annual net assets in excess of $1 billion. Prior to
April 27, 1998, when the Fund was still organized as a closed-end investment
company, management fees were paid to the Manager at an annual fee of 0.65% on
the Fund's average annual net assets.

          Mitchell Hutchins Asset Management Inc. served as the Fund's
Administrator until April 24, 1998. The Fund paid the Administrator an annual
fee of 0.20% of the Fund's average annual net assets.

          The Manager acts as the accounting agent for the Fund at an annual fee
of $18,000, plus out-of-pocket costs and expenses reasonably incurred.

          Effective April 27, 1998, 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. Shareholder Financial
Services, Inc. (SFSI), a wholly-owned subsidiary of the Manager, was the
transfer agent and registrar for the Fund until April 27, 1998. Fees paid to
SFSI were based on the number of accounts and the number of shareholder
transactions, plus out-of-pocket costs and expenses.

          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 0.25% 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.

          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 shares 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% per year to compensate dealers for
providing personal services for accounts that hold Class B and C shares. Each
fee is computed on the average annual net assets of Class B or Class C shares,
determined as of the close of each regular business day. 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.

5. Forward Contracts

A forward foreign currency exchange contract (forward contract) is a commitment
to purchase or sell a foreign currency at a future date, at a negotiated rate.
The Fund uses forward contracts to seek to manage foreign currency risks. They
may also be used to tactically shift portfolio currency risk. The Fund generally
enters into forward contracts as a hedge upon the purchase or sale of a security
denominated in a foreign currency. In addition, the Fund may enter into such
contracts as a hedge against changes in foreign currency exchange rates on
portfolio positions.

          Forward contracts are valued based on the closing prices of the
forward currency contract rates in the London foreign exchange markets on a
daily basis as provided by a reliable bank or dealer. The Fund will realize a
gain or loss upon the closing or settlement of the forward transaction.

          Securities held in segregated accounts to cover net exposure on
outstanding forward contracts are noted in the Statement of Investments where
applicable. Unrealized appreciation or depreciation on forward contracts is
reported in the Statement of Assets and Liabilities. Realized gains and losses
are reported with all other foreign currency gains and losses in the Fund's
Statement of Operations.

          Risks include the potential inability of the counterparty to meet the
terms of the contract and unanticipated movements in the value of a foreign
currency relative to the U.S. dollar.

At April 30, 1998, the Fund had outstanding forward contracts as follows:

6. 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 or cost
effective 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.

          Securities held in collateralized accounts to cover initial margin
requirements on open futures contracts are noted in the Statement of
Investments. The Statement of Assets and Liabilities reflects a receivable
and/or payable for the daily mark to market for variation margin.

          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.

At April 30, 1998, the Fund had outstanding futures contracts as follows:

================================================================================
7. Option Activity

The Fund may buy and sell put and call options, or write put and covered call
options on portfolio securities in order to produce incremental earnings or
protect against changes in the value of portfolio securities.

          The Fund generally purchases put options or writes covered call
options to hedge against adverse movements in the value of portfolio holdings.
When an option is written, the Fund receives a premium and becomes obligated to
sell or purchase the underlying security at a fixed price, upon exercise of the
option.

          Options are valued daily based upon the last sale price on the
principal exchange on which the option is traded and unrealized appreciation or
depreciation is recorded. The Fund will realize a gain or loss upon the
expiration or closing of the option transaction. When an option is exercised,
the proceeds on sales for a written call option, the purchase cost for a written
put option, or the cost of the security for a purchased put or call option is
adjusted by the amount of premium received or paid.

          Securities designated to cover outstanding call options are noted in
the Statement of Investments where applicable. Shares subject to call,
expiration date, exercise price, premium received and market value are detailed
in a footnote to the Statement of Investments. Options written are reported as a
liability in the Statement of Assets and Liabilities. Gains and losses are
reported in the Statement of Operations.

          The risk in writing a call option is that the Fund gives up the
opportunity for profit if the market price of the security increases and the
option is exercised. The risk in writing a put option is that the Fund may incur
a loss if the market price of the security decreases and the option is
exercised. The risk in buying an option is that the Fund pays a premium whether
or not the option is exercised. The Fund also has the additional risk of not
being able to enter into a closing transaction if a liquid secondary market does
not exist.

Written option activity for the six months ended April 30, 1998 was as follows:

                             Call Options               Put Options

8. Illiquid and Restricted Securities

At April 30, 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 or 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 April 30, 1998 was $5,108,319, which represents
9.95% of the Fund's net assets.

================================================================================
9. 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 period ended April
30, 1998.
