Zack, Esq.

REPORTS TO STOCKHOLDERS. 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 July 31, 2003, followed by a graphical comparison of the Fund's performance to an appropriate broad-based market index. Management's Discussion of Fund Performance. For the 12-month period ended July 31, 2003, Oppenheimer Main Street Opportunity Fund(R) produced a total return of 15.30% for its Class A shares (without sales charge), compared with the 11.98% return for the Russell 3000 Index, over the same period. The primary factor supporting the Fund's strong relative performance during the 12-month reporting period was its emphasis on micro-, small- and mid-cap stocks, and its correspondingly light exposure to large- and mega-cap stocks compared to its benchmark. For some time now, our quantitative models have predicted that smaller-cap stocks would produce higher rates of return than larger-cap stocks. This continued to be the case throughout the reporting period, and the Fund benefited when smaller-cap stocks led the second-quarter 2003 market rally. In fact, the smallest stocks in the universe of U.S. companies (micro-cap) outperformed the largest stocks (mega-cap) by 25.4% during the reporting period. The Fund also benefited by remaining fully invested throughout the reporting period, enabling it to capture the benefits of the market's 2003 advance more completely. In addition, the Fund remained very broadly diversified, holding nearly 1,100 stocks as of July 31, 2003. At the end of the reporting period, no stock was on average overweighted by more than 0.40% relative to the Fund's benchmark. This risk-management strategy helped to prevent disappointments in any single stock from having a disproportionate effect on the overall portfolio. It may be interesting for shareholders to note that, while the list of the Fund's top ten holdings includes a number of the market's largest companies, the Fund's exposure to most of those large companies is substantially less than that of the benchmark. Instead, we believe that a better indicator of the Fund's strategic position is a view of its largest over-weights, which are concentrated among smaller companies, and its largest under-weights, which are all mega-cap stocks with market capitalizations of more than $48.2 billion. Although our bottom-up stock selection process led to modest over- and under-weights in the various economic sectors that comprise the Russell 3000 Index, the way assets were allocated among industry groups ultimately had little bearing on the Fund's performance during the reporting period. As of July 31, 2003, the Fund's greatest over-weights were in the consumer discretionary, industrials and energy groups. The Fund's greatest under-weights were in the financial and consumer staples areas. Similarly, neither growth- nor value-oriented stocks provided a clear advantage during the reporting period. As of July 31, 2003, the Fund featured growth characteristics that 5 | OPPENHEIMER MAIN STREET OPPORTUNITY FUND FUND PERFORMANCE DISCUSSION were 16% to 43% higher than those of the benchmark, and valuation ratios that were 2% to 4% lower than the market averages. As of July 31, 2003, the percentage of the Fund's assets allocated to small- and micro-cap stocks declined modestly to approximately 48% of the portfolio from 54.6% at the end of 2002. The allocation to mid-cap stocks was about 23.2% of the portfolio at period's end, down about 7% over the last seven months. At the same time, assets allocated to large- and mega-cap stocks rose to about 28.7% of the portfolio. These trends are a result of the cap size specific rankings generated by our quantitative models, suggesting that small stocks currently remain more attractive than large ones, but less so than at the start of the reporting period. It is important to understand that the Fund is not managed according to our view of market trends, industry conditions or macroeconomic forces. Instead, we base our investment decisions on the disciplined application of quantitative models combined with the judgment of experienced portfolio managers. Our bottom-up, multi-factor quantitative models help us identify the stocks that, in our view, are most likely to outperform the market. The Fund's holdings, allocations and management strategies are subject to change. Comparing the Fund's Performance to the Market. The graphs that follow show the performance of a hypothetical $10,000 investment in each Class of shares of the Fund held until July 31, 2003. For Class A, B, C and Y shares, performance is measured from commencement of the classes on September 25, 2000. 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 and the applicable contingent deferred sales charge for Class B, Class C and Class N shares. The graphs assume that all dividends and capital gains distributions were reinvested in additional shares. The Fund's performance is compared to the performance of the Russell 3000 Index. The Russell 3000 Index is composed of 3,000 large U.S. companies by market capitalization, representing approximately 98% of the U.S. equity market. The smallest company in the Russell 3000 Index has a market value of roughly $25 million. The largest has a market value of about $70 billion. Index performance reflects the reinvestment of dividends but does not consider the effect of capital gains or transaction costs, and none of the data in the graphs that follow shows the effect of taxes. The Fund's performance reflects the effects of Fund business and operating expenses. While index comparisons may be useful to provide a benchmark for the Fund's performance, it must be noted that the Fund's investments are not limited to the investments in the index. 6 | OPPENHEIMER MAIN STREET OPPORTUNITY FUND Class A Shares Comparison of Change in Value of $10,000 Hypothetical Investments in: Oppenheimer Main Street Opportunity Fund(R) (Class A) Russell 3000 Index [LINE CHART] Value of Investment Russell 3000 Date In Fund Index 09/25/2000 $9,425 $10,000 10/31/2000 9,218 9,858 01/31/2001 9,714 9,411 04/30/2001 9,638 8,635 07/31/2001 9,874 8,403 10/31/2001 9,214 7,377 01/31/2002 10,015 7,956 04/30/2002 10,459 7,708 07/31/2002 8,752 6,508 10/31/2002 8,544 6,318 01/31/2003 8,346 6,167 04/30/2003 8,931 6,629 07/31/2003 10,091 7,288 Average Annual Total Returns of Class A Shares of the Fund at 7/31/03* 1-Year 8.67% Since Inception 0.32% Class B Shares Comparison of Change in Value of $10,000 Hypothetical Investments in: Oppenheimer Main Street Opportunity Fund(R) (Class B) Russell 3000 Index [LINE CHART] Value of Investment Russell 3000 Date In Fund Index 09/25/2000 $10,000 $10,000 10/31/2000 9,780 9,858 01/31/2001 10,280 9,411 04/30/2001 10,180 8,635 07/31/2001 10,400 8,403 10/31/2001 9,700 7,377 01/31/2002 10,520 7,956 04/30/2002 10,960 7,708 07/31/2002 9,150 6,508 10/31/2002 8,920 6,318 01/31/2003 8,700 6,167 04/30/2003 9,290 6,629 07/31/2003 10,170 7,288 Average Annual Total Returns of Class B Shares of the Fund at 7/31/03* 1-Year 9.43% Since Inception 0.59% *See Notes on page 10 for further details.

Significant Accounting Policies Oppenheimer Main Street Opportunity 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 seek long-term capital appreciation. The Fund's investment advisor is OppenheimerFunds, Inc. (the Manager). The Fund offers Class A, Class B, Class C, Class N and Class Y 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. Class Y shares are sold to certain institutional investors without either a front-end sales charge or a CDSC. All classes of shares have identical rights and voting privileges. Earnings, net assets and net asset value per share may differ by minor amounts due to each class having its own expenses directly attributable to that class. Classes A, B, C and N have separate distribution and/or service plans. No such plan has been adopted for Class Y shares. Class B shares will automatically convert to Class A shares six years after the date of purchase. The following is a summary of significant accounting policies consistently followed by the Fund. - -------------------------------------------------------------------------------- Securities Valuation. Securities 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. Securities (including restricted securities) for which quotations are not readily available are valued primarily using dealer-supplied valuations, a portfolio pricing service authorized by the Board of Trustees, or at their fair value. Fair value is determined in good faith using consistently applied procedures under the supervision of the Board of Trustees. Short-term "money market type" debt securities with remaining maturities of sixty days or less are valued at 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 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. 41 | OPPENHEIMER MAIN STREET OPPORTUNITY FUND NOTES TO FINANCIAL STATEMENTS Continued - -------------------------------------------------------------------------------- 1. Significant Accounting Policies Continued 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. Secured by U.S. government securities, 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 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 investment for federal income tax purposes. Net Unrealized Undistributed Appreciation Based Net Undistributed Accumulated on Cost of Securities Investment Long-Term Loss for Federal Income Income Gain Carryforward 1,2,3 Tax Purposes ------------------------------------------------------------------------------ $-- $-- $103,602,101 $145,915,578 1. As of July 31, 2003, the Fund had $79,504,753 of net capital loss carryforwards available to offset future realized capital gains, if any, and thereby reduce future taxable gain distributions. As of July 31, 2003, details of the capital loss carryforwards were as follows: Expiring ---------------------- 2009 $ 66,509 2010 8,390,169 2011 71,048,075 ----------- Total $79,504,753 =========== 2. During the fiscal years ended July 31, 2003 and July 31, 2002, the Fund did not utilize any capital loss carryforwards. 3. As of July 31, 2003, the Fund had $24,097,348 of post-October losses available to offset future capital gains, if any. Such losses, if unutilized, will expire in 2012. 42 | OPPENHEIMER MAIN STREET OPPORTUNITY FUND 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 July 31, 2003. Net assets of the Fund were unaffected by the reclassifications. From To Net Ordinary Capital Tax Return Investment Loss Loss of Capital Loss - ------------------------------------------------------------------------------------------ $2,866,138 $209,393 $-- $2,656,747 No distributions were paid during the years ended July 31, 2003 and July 31, 2002. The aggregate cost of investments and the composition of unrealized appreciation and depreciation of investments for federal income tax purposes as of July 31, 2003 are noted below. The primary difference between book and tax appreciation or depreciation of investments, if applicable, is attributable to the tax deferral of losses or tax realization of financial statement unrealized gain or loss. Federal Tax Cost $812,551,245 ============ Gross unrealized appreciation $160,595,716 Gross unrealized depreciation (14,680,138) ------------ Net unrealized appreciation $145,915,578 ============ - -------------------------------------------------------------------------------- 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 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 accounting principles generally accepted in the United States of America 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.

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 gain or loss. Such realized gains and losses are reported with all other foreign currency gains and losses in the Statement of Operations. As of July 31, 2003, the Fund had no outstanding foreign currency contracts. 46 | OPPENHEIMER MAIN STREET OPPORTUNITY FUND - -------------------------------------------------------------------------------- 6. Illiquid or Restricted Securities As of July 31, 2003, investments in securities included issues that are illiquid or restricted. Restricted securities are purchased in private placement transactions, are not registered under the Securities Act of 1933, may have contractual restrictions on resale, and are valued under methods approved by the Board of Trustees as reflecting fair value. A security may also be considered illiquid if it lacks a readily available market or if its valuation has not changed for a certain period of time. The Fund intends to invest no more than 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 limitation. The aggregate value of illiquid or restricted securities subject to this limitation as of July 31, 2003 was $660,694, which represents 0.07% of the Fund's net assets, of which $651,481 is considered restricted.

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 auditing standards generally accepted in the United States of America. 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, 2003, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. 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 Main Street Opportunity Fund as of July 31, 2003, 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 the periods indicated, in conformity with accounting principles generally accepted in the United States of America.
