FUND PERFORMANCE DISCUSSION
- --------------------------------------------------------------------------------

HOW HAS THE FUND PERFORMED? BELOW IS A DISCUSSION BY OPPENHEIMERFUNDS, INC., OF
THE FUND'S PERFORMANCE DURING ITS FISCAL YEAR ENDED AUGUST 31, 2004, FOLLOWED BY
A GRAPHICAL COMPARISON OF THE FUND'S PERFORMANCE TO AN APPROPRIATE BROAD-BASED
MARKET INDEX.

MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE. As discussed earlier
in this report, the Fund's performance over the fiscal year that ended August
31, 2004 compared very favorably to that of its peers and its benchmark. Given
our significant positions in Brazil and India--over 30% of the portfolio's value
at the end of the reporting period--our returns certainly reflected the overall
strength of these markets during this reporting period.

     It is important to note that the Fund's geographical and industry sector
weightings were the result of individual stock selection rather than an attempt
to replicate an index. Our goal is to invest in businesses with good managements
and exciting prospects, ideally, before they are widely recognized--regardless
of location or industry. Consequently, the Fund's performance doesn't
necessarily track with an index or broad market trends.

     In terms of significant individual contributors to performance over the
last twelve months, Grupo Financiero Inbursa SA de CV proved exceptional.
Inbursa is a Mexico-based financial group whose companies include some of the
country's highly profitable and well-run banking, insurance and private equities
businesses. We had owned Inbursa for years and, with the demand for credit in
Mexico growing, we were optimistic about the stock.

     Another top holding and our single best performer over this period was SK
Corp. The leading oil refiner and marketer in South Korea, SK Corp. also owns
the largest network of gas stations in the country and is the biggest
shareholder of SK Telecom Co. Ltd, a major wireless communication services
provider. A combination of events last year--including the upsurge in oil prices
which lifted the company's refining margins--turned out to be very favorable for
the stock price.

     Brazilian retailer, Lojas Americanas SA, Preference also continued to
shine. A restructuring play when we acquired the stock a few years ago, the
Brazilian company has refocused the business, improved efficiency and increased
sales. They are now generating substantial cash returns and have become Brazil's
leading Internet shopping site.

     Among our larger investments that disappointed were Sinotrans, Ltd. and SM
Prime Holdings, Inc. Sinotrans, Ltd., a Chinese freight forwarding company, lost
ground this year as competition intensified which negatively impacted its profit
margins. We think this development is a temporary phenomenon and the longer term
outlook for both the company and its business remains bright. SM Prime Holdings,
which we also believe was undervalued, is a shopping mall owner, developer and
operator in the Philippines. It was the dominant player in a growing industry
and may continue to enjoy

FUND PERFORMANCE DISCUSSION
- --------------------------------------------------------------------------------

very favorable economic circumstances. We feel the market is misunderstanding
the long-term value of this business, creating even more opportunity for us.

     Regarding some of the more strategic decisions made during this reporting
period, the Fund boosted allocations in countries where we believe interest
rates will likely continue to decline, such as Brazil and South Africa. We also
built our position in undervalued commodities, particularly those produced by
major companies located in areas likely to experience a shortage or price
squeeze. For example, we recently purchased two platinum stocks based in South
Africa. Seventy-five percent of the world's platinum supply comes from South
Africa, and these two companies are the leading producers. Based on their
underlying fundamentals, the metal's limited availability, growing world demand
and other factors, we believe these stocks could benefit over the next few
years.

     In closing, we remind shareholders that investing in foreign markets,
especially in the securities of emerging countries, poses considerable risks,
including heightened volatility, political and economic uncertainty, currency
fluctuations and higher expenses.

COMPARING THE FUND'S PERFORMANCE TO THE MARKET. The graphs that follow show the
performance of a hypothetical $10,000 investment in each class of shares of the
Fund held until August 31, 2004. In the case of Class A, Class B and Class C
shares, performance is measured from the inception of the Classes on November
18, 1996. In the case of Class N shares, performance is measured from inception
of the Class on March 1, 2001. The Fund's performance reflects the deduction of
the maximum initial sales charge on Class A shares, the applicable contingent
deferred sales charge on Class B, Class C, and Class N shares, and reinvestments
of all dividends and capital gains distributions. Past performance cannot
guarantee future results.

     The Fund's performance is compared to the performance of the Morgan Stanley
Capital International (MSCI) Emerging Markets Free Index, an unmanaged
capitalization-weighted equity index of issuers located in 25 developing
markets. The MSCI Emerging Markets Free Index is widely recognized as a measure
of performance in developing markets. Index performance reflects the
reinvestment of income but does not consider the effect of transaction costs,
and none of the data in the graphs shows the effect of taxes. The Fund's
performance reflects the effects of the Fund's business and operating expenses.
While index comparisons may be useful to provide a benchmark for the Fund's
performance, it must be noted that the Fund's investments are not limited to the
investments in the index.

NOTES
- --------------------------------------------------------------------------------

Total returns and the ending account values in the graphs include changes in
share price and reinvestment of dividends and capital gains distributions in a
hypothetical investment for the periods shown. The Fund's total returns shown do
not reflect the deduction of income taxes on an individual's investment. Taxes
may reduce your actual investment returns on income or gains paid by the Fund or
any gains you may realize if you sell your shares.

Investors should consider the Fund's investment objectives, risks, and other
charges and expenses carefully before investing. The Fund's prospectus contains
this and other information about the Fund, and may be obtained by asking your
financial advisor, calling us at 1.800.525.7048 or visiting our website at
www.oppenheimerfunds.com. Read the prospectus carefully before investing.

The Fund's investment strategy and focus can change over time. The mention of
specific fund holdings does not constitute a recommendation by OppenheimerFunds,
Inc.

CLASS A shares of the Fund were first publicly offered on 11/18/96. Unless
otherwise noted, Class A returns include the maximum initial sales charge of
5.75%.

CLASS B shares of the Fund were first publicly offered on 11/18/96. Unless
otherwise noted, Class B returns include the applicable contingent deferred
sales charge of 5% (1-year) and 2% (5-year). Because Class B shares convert to
Class A shares 72 months after purchase, the "since inception" return for Class
B uses Class A performance for the period after conversion. Class B shares are
subject to an annual 0.75% asset-based sales charge.

CLASS C shares of the Fund were first publicly offered on 11/18/96. Unless
otherwise noted, Class C returns include the contingent deferred sales charge of
1% for 1-year period. Class C shares are subject to a 0.75% annual asset-based
sales charge.

CLASS N shares of the Fund were first publicly offered on 3/1/01. Class N shares
are offered only through retirement plans. Unless otherwise noted, Class N
returns include the contingent deferred sales charge of 1% for the 1-year
period. Class N shares are subject to an annual 0.25% asset-based sales charge.

An explanation of the calculation of performance is in the Fund's Statement of
Additional Information.

FUND EXPENSES
- --------------------------------------------------------------------------------

FUND EXPENSES. As a shareholder of the Fund, you incur two types of costs: (1)
transaction costs, which may include sales charges (loads) on purchase payments;
contingent deferred sales charges on redemptions; and redemption fees, if any;
and (2) ongoing costs, including management fees; distribution and service fees;
and other Fund expenses. These examples are intended to help you understand your
ongoing costs (in dollars) of investing in the Fund and to compare these costs
with the ongoing costs of investing in other mutual funds.

The examples are based on an investment of $1,000.00 invested at the beginning
of the period and held for the entire 6-month period ended August 31, 2004.

ACTUAL EXPENSES. The "actual" lines of the table provide information about
actual account values and actual expenses. You may use the information on this
line for the class of shares you hold, together with the amount you invested, to
estimate the expense that you paid over the period. Simply divide your account
value by $1,000.00 (for example, an $8,600.00 account value divided by $1,000.00
= 8.60), then multiply the result by the number in the "actual" line under the
heading entitled "Expenses Paid During Period" to estimate the expenses you paid
on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES. The "hypothetical" lines of the
table provide information about hypothetical account values and hypothetical
expenses based on the Fund's actual expense ratio for each class of shares, and
an assumed rate of return of 5% per year before expenses, which is not the
Fund's actual return. The hypothetical account values and expenses may not be
used to estimate the actual ending account balance or expenses you paid for the
period. You may use this information to compare the ongoing costs of investing
in the Fund and other funds. To do so, compare this 5% hypothetical example for
the class of shares you hold with the 5% hypothetical examples that appear in
the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as front-end
or contingent deferred sales charges (loads), redemption fees, or a $12.00 fee
imposed annually on accounts valued at less than $500.00 (subject to


                    18 | OPPENHEIMER DEVELOPING MARKETS FUND



exceptions described in the Statement of Additional Information). Therefore, the
"hypothetical" lines of the table are useful in comparing ongoing costs only,
and will not help you determine the relative total costs of owning different
funds. In addition, if these transactional costs were included, your costs would
have been higher.

Hypothetical assumes 5% annual return before expenses.

Expenses are equal to the Fund's annualized expense ratio for that class,
multiplied by the average account value over the period, multiplied by 184/366
(to reflect the one-half year period). Those expense ratios for the 6-month
period ended August 31, 2004 are as follows:

The expense ratios reflect voluntary reimbursements of expenses by the Fund's
Transfer Agent that can be terminated at any time, without advance notice. The
"Financial Highlights" tables in the Fund's financial statements, included in
this report, also show the gross expense ratios, without such reimbursements.

NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
1. SIGNIFICANT ACCOUNTING POLICIES

Oppenheimer Developing Markets Fund (the Fund) is registered under the
Investment Company Act of 1940, as amended, as an open-end management investment
company. The Fund's investment objective is to aggressively seek capital
appreciation. The Fund's investment advisor is OppenheimerFunds, Inc. (the
Manager).

     The Fund offers Class A, Class B, Class C and Class N shares. Class A
shares are sold at their offering price, which is normally net asset value plus
a front-end sales charge. Class B, Class C and Class N shares are sold without a
front-end sales charge but may be subject to a contingent deferred sales charge
(CDSC). Class N shares are sold only through retirement plans. Retirement plans
that offer Class N shares may impose charges on those accounts. All classes of
shares have identical rights and voting privileges with respect to the Fund in
general and exclusive voting rights on matters that affect that class alone.
Earnings, net assets and net asset value per share may differ due to each class
having its own expenses, such as transfer and shareholder servicing agent fees
and shareholder communications, directly attributable to that class. Class A, B,
C and N have separate distribution and/or service plans. Class B shares will
automatically convert to Class A shares six years after the date of purchase.
The Fund assesses a 2% fee on the proceeds of fund shares that are redeemed
(either by selling or exchanging to another Oppenheimer fund) within 30 days of
their purchase. The fee, which is retained by the Fund, is accounted for as an
addition to paid-in capital.

     The following is a summary of significant accounting policies consistently
followed by the Fund.

- --------------------------------------------------------------------------------
SECURITIES VALUATION. The Fund calculates the net asset value of its shares as
of the close of The New York Stock Exchange (the Exchange), normally 4:00 P.M.
Eastern time, on each day the Exchange is open for business. Securities listed
or traded on National Stock Exchanges or other domestic or foreign exchanges are
valued based on the last sale price of the security traded on that exchange
prior to the time when the Fund's assets are valued. Securities traded on NASDAQ
are valued based on the closing price provided by NASDAQ prior to the time when
the Fund's assets are valued. In the absence of a sale, the security is valued
at the last sale price on the prior trading day, if it is within the spread of
the closing bid and asked prices, and if not, at the closing bid price.
Corporate, government and municipal debt instruments having a remaining maturity
in excess of 60 days and all mortgage-backed securities will be valued at the
mean between the "bid" and "asked" prices. Securities may be valued primarily
using dealer-supplied valuations or a portfolio pricing service authorized by
the Board of Trustees. Securities (including restricted securities) for which
market quotations are not readily available are valued at their fair value.
Foreign and domestic securities whose values have been materially affected by
what the Manager identifies as a significant event occurring before the Fund's
assets are valued but after the close of their respective exchanges will be fair
valued. Fair value is determined in good faith using consistently applied
procedures under the supervision of the Board of Trustees. Short-term "money
market type" debt securities with

- --------------------------------------------------------------------------------
1. SIGNIFICANT ACCOUNTING POLICIES Continued

remaining maturities of sixty days or less are valued at amortized cost (which
approximates market value).

- --------------------------------------------------------------------------------
FOREIGN CURRENCY TRANSLATION. The Fund's accounting records are maintained in
U.S. dollars. Prices of securities denominated in foreign currencies are
translated into U.S. dollars as of the close of The New York Stock Exchange (the
Exchange), normally 4:00 P.M. Eastern time, on each day the Exchange is open for
business. 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. Foreign exchange rates may be valued
primarily using dealer supplied valuations or a portfolio pricing service
authorized by the Board of Trustees.

     Reported net realized foreign exchange gains or losses arise from sales of
portfolio securities, sales and maturities of short-term securities, sales of
foreign currencies, currency gains or losses realized between the trade and
settlement dates on securities transactions, and the difference between the
amounts of dividends, interest, and foreign withholding taxes recorded on the
Fund's books and the U.S. dollar equivalent of the amounts actually received or
paid. Net unrealized foreign exchange gains and losses arise from changes in the
values of assets and liabilities, including investments in securities at fiscal
period end, resulting from changes in exchange rates.

     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.

- --------------------------------------------------------------------------------
JOINT REPURCHASE AGREEMENTS. Pursuant to an Exemptive Order issued by the
Securities and Exchange Commission, the Fund, along with other affiliated funds
advised by the Manager, may transfer uninvested cash balances into joint trading
accounts on a daily basis. These balances are invested in one or more repurchase
agreements. Securities pledged as collateral for repurchase agreements are held
by a custodian bank until the agreements mature. Each agreement requires that
the market value of the collateral be sufficient to cover payments of interest
and principal. In the event of default by the other party to the agreement,
retention of the collateral may be subject to legal proceedings.

- --------------------------------------------------------------------------------
ALLOCATION OF INCOME, EXPENSES, GAINS AND LOSSES. Income, expenses (other than
those attributable to a specific class), gains and losses are allocated on a
daily basis to each class of shares based upon the relative proportion of net
assets represented by such class. Operating expenses directly attributable to a
specific class are charged against the operations of that class.

- --------------------------------------------------------------------------------
FEDERAL TAXES. The Fund intends to comply with provisions of the Internal
Revenue Code applicable to regulated investment companies and to distribute
substantially all of its investment company taxable income, including any net
realized gain on investments


                    36 | OPPENHEIMER DEVELOPING MARKETS FUND



not offset by capital loss carryforwards, if any, to shareholders, therefore, no
federal income or excise tax provision is required.

The tax components of capital shown in the table below represent distribution
requirements the Fund must satisfy under the income tax regulations, losses the
Fund may be able to offset against income and gains realized in future years and
unrealized appreciation or depreciation of securities and other investments for
federal income tax purposes.

1. The Fund had $594,538 of post-October foreign currency losses which were
deferred.

2. The Fund had $8,691,799 of post-October passive foreign investment company
losses which were deferred.

3. During the fiscal year ended August 31, 2004, the Fund utilized $19,295,605
of capital loss carryforward to offset capital gains realized in that fiscal
year.

4. During the fiscal year ended August 31, 2003, the Fund did not utilize any
capital loss carryforward.

Net investment income (loss) and net realized gain (loss) may differ for
financial statement and tax purposes. The character of dividends and
distributions made during the fiscal year from net investment income or net
realized gains may differ from their ultimate characterization for federal
income tax purposes. Also, due to timing of dividends and distributions, the
fiscal year in which amounts are distributed may differ from the fiscal year in
which the income or net realized gain was recorded by the Fund. Accordingly, the
following amounts have been reclassified for August 31, 2004. Net assets of the
Fund were unaffected by the reclassifications.

Certain foreign countries impose a tax on capital gains which is accrued by the
Fund based on unrealized appreciation, if any, on affected securities. The tax
is paid when the gain is realized.

- --------------------------------------------------------------------------------
TRUSTEES' COMPENSATION. The Fund has adopted an unfunded 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 August
31, 2004, the Fund's projected benefit obligations were increased by $13,214 and
payments of $3,812 were made to retired trustees, resulting in an accumulated
liability of $53,767 as of August 31, 2004.

     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 the annual compensation they are entitled to receive from the Fund.
For purposes of determining the amount owed to the Trustee under the plan,
deferred amounts are treated as though equal dollar amounts had been invested in
shares of the Fund or in other Oppenheimer funds selected by the Trustee. The
Fund purchases shares of the funds selected for deferral by the Trustee in
amounts equal to his or her deemed investment, resulting in a Fund asset equal
to the deferred compensation liability. Such assets are included as a component
of "Other" within the asset section of the Statement of Assets and Liabilities.
Deferral of trustees' fees under the plan will not affect the net assets of the
Fund, and will not materially affect the Fund's assets, liabilities or net
investment income per share. Amounts will be deferred until distributed in
accordance to the Plan.

- --------------------------------------------------------------------------------
DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions to
shareholders, which are determined in accordance with income tax regulations,
are recorded on the ex-dividend date. Income and capital gain distributions, if
any, are declared and paid annually.

- --------------------------------------------------------------------------------
INVESTMENT INCOME. Dividend income is recorded on the ex-dividend date or upon
ex-dividend notification in the case of certain foreign dividends where the
ex-dividend date may have passed. Non-cash dividends included in dividend
income, if any, are recorded at the fair market value of the securities
received. Interest income, which includes accretion of discount and amortization
of premium, is accrued as earned.

- --------------------------------------------------------------------------------
EXPENSE OFFSET ARRANGEMENT. The reduction of custodian fees, if applicable,
represents earnings on cash balances maintained by the Fund.

- --------------------------------------------------------------------------------
SECURITY TRANSACTIONS. Security transactions are recorded on the trade date.
Realized gains and losses on securities sold are determined on the basis of
identified cost.

- --------------------------------------------------------------------------------
OTHER. The preparation of financial statements in conformity with U.S. 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.

3. PURCHASES AND SALES OF SECURITIES

The aggregate cost of purchases and proceeds from sales of securities, other
than short-term obligations, for the year ended August 31, 2004, were
$1,015,247,737 and $196,431,554, respectively.

- --------------------------------------------------------------------------------
4. FEES AND OTHER TRANSACTIONS WITH AFFILIATES

MANAGEMENT FEES. Management fees paid to the Manager were in accordance with the
investment advisory agreement with the Fund which provides for a fee at an
annual rate of 1.00% of the first $250 million of average annual net assets of
the Fund, 0.95% of the next $250 million, 0.90% of the next $500 million and
0.85% of average annual net assets over $1 billion.

- --------------------------------------------------------------------------------
TRANSFER AGENT FEES. OppenheimerFunds Services (OFS), a division of the Manager,
acts as the transfer and shareholder servicing agent for the Fund. The Fund pays
OFS a per account fee. For the year ended August 31, 2004, the Fund paid
$3,384,804 to OFS for services to the Fund.

- --------------------------------------------------------------------------------
DISTRIBUTION AND SERVICE PLAN (12b-1) FEES. Under its General Distributor's
Agreement with the Fund, OppenheimerFunds Distributor, Inc. (the Distributor)
acts as the Fund's principal underwriter in the continuous public offering of
the Fund's classes of shares.

- --------------------------------------------------------------------------------
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 0.25% of the average annual net assets of
Class A shares of the Fund. The Distributor currently uses all of those fees
to pay dealers, brokers, banks and other financial institutions quarterly for
providing personal services and maintenance of accounts of their customers that
hold Class A shares. Any unreimbursed expenses the Distributor incurs with
respect to Class A shares in any fiscal year cannot be recovered in subsequent
years. Fees incurred by the Fund under the Plan are detailed in the Statement of
Operations.

- --------------------------------------------------------------------------------
DISTRIBUTION AND SERVICE PLANS FOR CLASS B, CLASS C AND CLASS N SHARES. The Fund
has adopted Distribution and Service Plans for Class B, Class C and Class N
shares to compensate the Distributor for its services in connection with the
distribution of those 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 and Class C shares and 0.25% per year on Class N shares. The Distributor
also receives a service fee of up to 0.25% per year under each plan. If either
the Class B, Class C or Class N plan is terminated by the Fund or by the
shareholders of a class, the Board of Trustees and its independent trustees must
determine whether the Distributor shall be entitled to payment from the Fund of
all or a portion of the service fee and/or asset-based sales charge in respect
to shares sold prior to the effective date of such termination. The
Distributors's aggregate uncompensated expenses under the plan at August 31,
2004 for Class B, Class C and Class N shares were

- --------------------------------------------------------------------------------
5. FOREIGN CURRENCY CONTRACTS

A foreign currency contract is a commitment to purchase or sell a foreign
currency at a future date, at a negotiated rate. The Fund may enter into foreign
currency contracts to settle specific purchases or sales of securities
denominated in a foreign currency and for protection from adverse exchange rate
fluctuation. Risks to the Fund include the potential inability of the
counterparty to meet the terms of the contract.

     The net U.S. dollar value of foreign currency underlying all contractual
commitments held by the Fund and the resulting unrealized appreciation or
depreciation are determined using prevailing foreign currency exchange rates.
Unrealized appreciation and depreciation on foreign currency contracts are
reported in the Statement of Assets and Liabilities as a receivable or payable
and in the Statement of Operations with the change in unrealized appreciation or
depreciation.

     The Fund may realize a gain or loss upon the closing or settlement of the
foreign transaction. Contracts closed or settled with the same broker are
recorded as net realized gains or losses. Such realized gains and losses are
reported with all other foreign currency gains and losses in the Statement of
Operations.

6. ILLIQUID SECURITIES

As of August 31, 2004, investments in securities included issues that are
illiquid. 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 will not invest more than 15% of its net assets (determined at the time of
purchase and reviewed periodically) in illiquid securities. The aggregate value
of illiquid securities subject to this limitation as of August 31, 2004 was
$27,364,963, which represents 1.46% of the Fund's net assets.

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

7. LITIGATION

Six complaints have been filed as putative derivative and class actions against
the Manager, OFS and the Distributor (collectively, "OppenheimerFunds"), as well
as 51 of the Oppenheimer funds (collectively, the "Funds") including this Fund,
and nine directors/trustees of certain of the Funds (collectively, the
"Directors/Trustees"). The complaints allege that the Manager charged excessive
fees for distribution and other costs, improperly used assets of the Funds in
the form of directed brokerage commissions and 12b-1 fees to pay brokers to
promote sales of the Funds, and failed to properly disclose the use of Fund
assets to make those payments in violation of the Investment Company Act of 1940
and the Investment Advisers Act of 1940. The complaints further allege that by
permitting and/or participating in those actions, the Directors/Trustees
breached their fiduciary duties to Fund shareholders under the Investment
Company Act of 1940 and at common law.

     OppenheimerFunds believes that it is premature to render any opinion as to
the likelihood of an outcome unfavorable to them, the Funds or the
Directors/Trustees and that no estimate can yet be made with any degree of
certainty as to the amount or range of any potential loss. However,
OppenheimerFunds, the Funds and the Directors/Trustees believe that the
allegations contained in the complaints are without merit and intend to defend
these lawsuits vigorously.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
- --------------------------------------------------------------------------------

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

THE BOARD OF TRUSTEES AND SHAREHOLDERS OF OPPENHEIMER DEVELOPING MARKETS FUND:

We have audited the accompanying statement of assets and liabilities of
Oppenheimer Developing Markets Fund, including the statement of investments, as
of August 31, 2004, and the related statement of operations for the year then
ended, the statements of changes in net assets for each of the two years in the
period then ended, and the financial highlights for each of the five years in
the period then ended. 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 the standards of the Public
Company Accounting Oversight Board (United States). 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 August 31, 2004, by correspondence with
the custodian and brokers or by other appropriate auditing procedures where
replies from brokers were not received. 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 Developing Markets Fund as of August 31, 2004, the results of its
operations for the year then ended, the changes in its net assets for each of
the two years in the period then ended, and the financial highlights for each of
the five years in the period then ended, in conformity with U.S. generally
accepted accounting principles.

FEDERAL INCOME TAX INFORMATION Unaudited
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
In early 2005, if applicable, shareholders of record will receive information
regarding all dividends and distributions paid to them by the Fund during
calendar year 2004. Regulations of the U.S. Treasury Department require the Fund
to report this information to the Internal Revenue Service.

     Dividends of $0.6183, $0.4981, $0.5284 and $0.6026 per share were paid to
Class A, Class B, Class C and Class N shareholders, respectively, on December
11, 2003, all of which was designated as ordinary income for federal income tax
purposes.

     None of the dividends paid by the Fund during the year ended August 31,
2004 are eligible for the corporate dividend-received deduction.

     A portion, if any, of the dividends paid by the Fund during the fiscal year
ended August 31, 2004 which are not designated as capital gain distributions are
eligible for lower individual income tax rates to the extent that the Fund has
received qualified dividend income as stipulated by recent tax legislation.
$28,058,119 of the Fund's fiscal year taxable income may be eligible for the
lower individual income tax rates. In early 2005, shareholders of record will
receive information regarding the percentage of distributions that are eligible
for lower individual income tax rates.

     The Fund has elected the application of Section 853 of the Internal Revenue
Code to permit shareholders to take a federal income tax credit or deduction, at
their option, on a per share basis for an aggregate amount of $7,617,623 of
foreign income taxes paid by the Fund during the fiscal year ended August 31,
2004. A separate notice will be mailed to each shareholder, which will reflect
the proportionate share of such foreign taxes which must be treated by
shareholders as gross income for federal income tax purposes.

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

              regularly scheduled meeting.

              Pre-approval of non-audit services is waived provided that: 1) the
              aggregate amount of all such services provided constitutes no more
              than five percent of the total amount of fees paid by the
              registrant to it principal accountant during the fiscal year in
              which services are provided 2) such services were not recognized
              by the registrant at the time of engagement as non-audit services
              and 3) such services are promptly brought to the attention of the
              audit committee of the registrant and approved prior to the
              completion of the audit.

              control with the adviser that provides ongoing services to the
              registrant related to non-audit fees. Those billings did not
              include any prohibited non-audit services as defined by the

         (h)  The registrant's audit committee of the board of directors has
              considered whether the provision of non-audit services that were
              rendered to the registrant's investment adviser, and any entity
              controlling, controlled by, or under common control with the

              compatible with maintaining the principal account's independence.
              No such services were rendered.

              Securities Exchange Act of 1934 (a) is accumulated and
              communicated to registrant's management, including its principal
