Zack, Esq. OppenheimerFunds, Inc. Two World Financial Center, New York, New York 10281-1008 ----------------------------------------------------------- (Name and address of agent for service) Registrant's telephone number, including area code: (303) 768-3200 Date of fiscal year end: JULY 31 Date of reporting period: AUGUST 1, 2003 - JULY 31, 2004 ITEM 1. 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, 2004, FOLLOWED BY A GRAPHICAL COMPARISON OF THE FUND'S PERFORMANCE TO AN APPROPRIATE BROAD-BASED MARKET INDEX. MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE. We attribute the Fund's strong relative performance primarily to its focus on small-cap stocks during the first half of the reporting period. As had been the case since the Fund's inception in September 2000, small-cap stocks consistently outperformed their large-cap counterparts during the reporting period's first half. Accordingly, the Fund benefited from its relatively heavy exposure to smaller-capitalizations stocks and its relatively light holdings of mega-cap stocks during that time. In addition to benefiting from its allocation strategy across market capitalizations, the Fund's stock selection strategy contributed positively to its performance in all capitalization ranges except the mega-cap range, where stock selection detracted modestly from the Fund's returns compared to the Russell 3000 Index. We do not actively allocate by sector but rather our stock selection process leads to sector allocations. Although energy stocks achieved higher absolute returns than any other market sector over the reporting period, the Fund's security selection and sector allocation strategies provided the greatest relative value among consumer discretionary stocks, followed by health care and energy. The Fund's security selection strategy contributed positively to its relative performance in all market sectors except the information technology area. In contrast, the Fund's sector allocation exerted relatively little influence over the Fund's relative performance during the reporting period, making the most meaningfully positive difference in the energy sector, where the Fund's relatively heavy exposure benefited returns. The Fund currently is positioned to benefit from what we believe to be a fundamental shift in market leadership toward larger-cap stocks. Our models indicate that the five-year cycle of small-cap outperformance that began in 1999 has probably come to an end. After having correctly favored smaller stocks during most of this period, a number of factors considered by our models--including interest rate spread indicators and relative valuation components--now favor large stocks over small ones. As a result, during the second half of the reporting period we substantially increased the Fund's investments in mega-cap stocks, which accounted for more than 50% of the portfolio at the end of the reporting period. In fact, all of the Fund's top-10 overweighted positions relative to the Russell 3000 benchmark were mega-cap stocks as of the end of the reporting period. In contrast, at the end of the previous reporting period (January 31, 2004), none of the top 10-overweighted positions were mega-cap stocks. From a sector 9 | OPPENHEIMER MAIN STREET OPPORTUNITY FUND FUND PERFORMANCE DISCUSSION - -------------------------------------------------------------------------------- allocation standpoint, the Fund ended the reporting period with a larger percentage of assets invested in energy and financial stocks than the Fund's benchmark, the Russell 3000 Index, and a smaller percentage allocated to utilities and consumer discretionary stocks. However, it should be noted that fundamental changes of this nature, when they occur quickly, take some time to be reflected in our quantitative models. In addition, we tend to make such changes to the portfolio gradually, with an eye toward managing transaction costs. As always, we remain committed to remaining fully invested in equities and to attempting to reduce risk and minimize transaction costs through a well diversified portfolio of stocks in all capitalization ranges. 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, 2004. In the case of Class A, Class B, Class C, and Class Y, performance is measured from inception 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, 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 Russell 3000 Index. The Russell 3000 Index is an unmanaged index of large-capitalization U.S. companies. 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. 10 | 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 [THE FOLLOWING TABLE WAS REPRESENTED BY A LINE GRAPH IN THE PRINTED MATERIAL.] 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 10/31/2003 11,270 7,815 01/31/2004 12,345 8,457 04/30/2004 11,986 8,294 07/31/2004 11,968 8,258 AVERAGE ANNUAL TOTAL RETURNS OF CLASS A SHARES WITH SALES CHARGE OF THE FUND AT 7/31/04 1-Year Since Inception - ------ --------------- 11.78% 4.78% Inception Date 9/25/00 THE PERFORMANCE DATA QUOTED REPRESENTS PAST PERFORMANCE, WHICH DOES NOT GUARANTEE FUTURE RESULTS.

An explanation of the calculation of performance is in the Fund's Statement of Additional Information. 16 | OPPENHEIMER MAIN STREET OPPORTUNITY FUND FUND EXPENSES - -------------------------------------------------------------------------------- FUND EXPENSES. As a shareholder of the Fund, you incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments, reinvested dividends, or other distributions; redemption fees; and exchange fees; 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 July 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), or a $12.00 fee imposed annually on accounts valued at less than $500.00 (subject to exceptions described in 17 | OPPENHEIMER MAIN STREET OPPORTUNITY FUND FUND EXPENSES - -------------------------------------------------------------------------------- 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.

Expenses are equal to the Fund's annualized expense ratio for that class, multiplied by the average account value over the period, multiplied by 182/366 (to reflect the one-half year period).

SEE ACCOMPANYING NOTES TO FINANCIAL STATEMENTS. 47 | OPPENHEIMER MAIN STREET OPPORTUNITY FUND NOTES TO FINANCIAL STATEMENTS - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 1. 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, however, the institutional investor 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. 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. 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 remaining maturities of sixty days or less are valued at amortized cost (which approximates market value). 48 | OPPENHEIMER MAIN STREET OPPORTUNITY FUND - -------------------------------------------------------------------------------- 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. 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. 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 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. 49 | OPPENHEIMER MAIN STREET OPPORTUNITY FUND NOTES TO FINANCIAL STATEMENTS Continued - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 1. SIGNIFICANT ACCOUNTING POLICIES Continued NET UNREALIZED APPRECIATION BASED ON COST OF SECURITIES AND UNDISTRIBUTED UNDISTRIBUTED ACCUMULATED OTHER INVESTMENTS NET INVESTMENT LONG-TERM LOSS FOR FEDERAL INCOME INCOME GAIN CARRYFORWARD 1,2 TAX PURPOSES ------------------------------------------------------------------------ $16,842,145 $106,612,843 $-- $72,959,058 1. During the fiscal year ended July 31, 2004, the Fund utilized $79,504,753 of capital loss carryforward to offset capital gains realized in that fiscal year. 2. During the fiscal year ended July 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 July 31, 2004. Net assets of the Fund were unaffected by the reclassifications. REDUCTION TO REDUCTION TO ACCUMULATED ACCUMULATED NET INCREASE TO NET INVESTMENT REALIZED GAIN PAID-IN CAPITAL LOSS ON INVESTMENTS 3 ----------------------------------------------------------------- $11,679,874 $3,356,403 $15,036,277 3. $11,679,874, including $10,086,466 of long-term capital gain, was distributed in connection with Fund share redemptions. No distributions were paid during the years ended July 31, 2004 and July 31, 2003. The aggregate cost of securities and other investments and the composition of unrealized appreciation and depreciation of securities and other investments for federal income tax purposes as of July 31, 2004 are noted below. The primary difference between book and tax appreciation or depreciation of securities and other investments, if applicable, is attributable to the tax deferral of losses or tax realization of financial statement unrealized gain or loss. Federal tax cost of securities $ 1,887,214,282 Federal tax cost of other investments 403,458 ---------------- Total federal tax cost $ 1,887,617,740 ================ Gross unrealized appreciation $ 142,472,776 Gross unrealized depreciation (69,513,718) ---------------- Net unrealized appreciation $ 72,959,058 ================ - -------------------------------------------------------------------------------- TRUSTEES' COMPENSATION. 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 50 | OPPENHEIMER MAIN STREET OPPORTUNITY FUND 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. - -------------------------------------------------------------------------------- 2.

The Class Y shares are subject to the minimum fees in the event that the 52 | OPPENHEIMER MAIN STREET OPPORTUNITY FUND per account fee does not equal or exceed the applicable minimum fees. OFS may voluntarily waive the minimum fees. - -------------------------------------------------------------------------------- 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 Distributor's aggregate uncompensated expenses under the plan at July 31, 2004 for Class B, Class C and Class N shares were $7,177,069, $3,302,368 and $450,211, respectively.

FEES AND OTHER TRANSACTIONS WITH AFFILIATES Continued PAYMENTS AND WAIVERS OF EXPENSES.

Subsequently, the Manager paid the Fund $106,541, an amount equivalent to certain of such commissions incurred in prior years.

During the year ended July 31, 2004, OFS waived $7,821, $4,676, $2,742 and $17,495 for Class A, Class B, Class C and Class N shares, respectively. This undertaking may be amended or withdrawn at any time. - -------------------------------------------------------------------------------- 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. As of July 31, 2004, the Fund had outstanding foreign currency contracts as follows: CONTRACT EXPIRATION AMOUNT VALUATION AS OF UNREALIZED CONTRACT DESCRIPTION DATE (000s) JULY 31, 2004 APPRECIATION - -------------------------------------------------------------------------------- CONTRACTS TO SELL Canadian Dollar [CAD] 8/3/04 536CAD $403,458 $1,173 - -------------------------------------------------------------------------------- 6. ILLIQUID OR RESTRICTED SECURITIES As of July 31, 2004, 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 will not invest 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 54 | OPPENHEIMER MAIN STREET OPPORTUNITY FUND investors, are not subject to that limitation. The aggregate value of illiquid or restricted securities subject to this limitation as of July 31, 2004 was $978,052, which represents 0.05% of the Fund's net assets, all of which is considered restricted. Information concerning restricted securities is as follows: ACQUISITION VALUATION AS OF UNREALIZED SECURITY DATE COST JULY 31, 2004 APPRECIATION - -------------------------------------------------------------------------------- STOCKS AND/OR WARRANTS Esprit Exploration Ltd. 6/4/02 $661,668 $978,052 $316,384 - -------------------------------------------------------------------------------- 7. SECURITIES LENDING The Fund lends portfolio securities from time to time in order to earn additional income. In return, the Fund receives collateral in the form of US Treasury obligations or cash, against the loaned securities and maintains collateral in an amount not less than 100% of the market value of the loaned securities during the period of the loan. The market value of the loaned securities is determined at the close of business of the funds and any additional required collateral is delivered to the Fund on the next business day. If the borrower defaults on its obligation to return the securities loaned because of insolvency or other reasons, the Fund could experience delays and cost in recovering the securities loaned or in gaining access to the collateral. Cash collateral is invested in cash equivalents. The Fund retains a portion of the interest earned from the collateral. The Fund also continues to receive interest or dividends paid on the securities loaned. As of July 31, 2004, the Fund had on loan securities valued at approximately $3,784,000. Cash of $3,773,307 was received as collateral for the loans, and has been invested in approved instruments. - -------------------------------------------------------------------------------- 8. SUBSEQUENT EVENTS - LITIGATION Three 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. 55 | OPPENHEIMER MAIN STREET OPPORTUNITY FUND REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- TO THE BOARD OF TRUSTEES AND SHAREHOLDERS OF OPPENHEIMER MAIN STREET OPPORTUNITY FUND: We have audited the accompanying statement of assets and liabilities of Oppenheimer Main Street Opportunity Fund, including the statement of investments, as of July 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 the periods presented. 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 July 31, 2004, 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, 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 the periods presented, in conformity with accounting principles generally accepted in the United States of America. DELOITTE & TOUCHE LLP Denver, Colorado September 21, 2004 56 | OPPENHEIMER MAIN STREET OPPORTUNITY FUND 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, if any, paid by the Fund during the fiscal year ended July 31, 2004 which are not designated as capital gain distributions should be multiplied by 97.38% to arrive at the amount eligible for the corporate dividend-received deduction. A portion, if any, of the dividends paid by the Fund during the fiscal year ended July 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. $18,106,732 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 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. 57 | OPPENHEIMER MAIN STREET OPPORTUNITY FUND PORTFOLIO PROXY VOTING POLICIES AND PROCEDURES Unaudited - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- The Fund has adopted Portfolio Proxy Voting Policies and Procedures under which the Fund votes proxies relating to securities ("portfolio proxies") held by the Fund.

SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS The Board is responsible for approving nominees for election as trustees. To assist in this task, the Board has designated the Audit Committee as the nominating committee for the Board. It reviews and recommends nominees to the Board. The Committee is comprised entirely of disinterested trustees as defined in Section 2(a)(19) of the Investment Company Act of 1940. The Audit Committee charter describes the responsibilities of the Committee in nominating candidates for election as independent Trustees of the Registrant. The Registrant's Board has adopted a written charter for the Committee. A current copy of the Audit Committee charter is available to shareholders on the OppenheimerFunds website at WWW.OPPENHEIMERFUNDS.COM. Under the current policy, if the Board determines that a vacancy exists or is likely to exist on the Board, the Audit Committee of the Board will consider candidates for Board membership including recommended by Registrant shareholders. The Audit Committee will consider nominees recommended by independent Board members or recommended by any other Board members including Board members affiliated with the Registrant's investment advisors. The Committee may, upon Board approval, retain an executive search firm to assist in screening potential candidates. Upon Board approval, the Audit Committee may also use the services of legal, financial, or other external counsel that it deems necessary or desirable in the screening process. Shareholders wishing to submit a nominee for election to the Board may do so by mailing their submission to the offices of OppenheimerFunds, Inc., 6803 South Tucson Way, Centennial, CO 80112, to the attention of the Board of Trustees of the named Registrant, c/o the Secretary of the Registrant. The Committee's process for identifying and evaluating nominees for trustees includes a number of factors. In screening candidates for board membership, whether the candidate is suggested by Board members, shareholders or others, the Committee considers the candidate's professional experience, soundness of judgment, integrity, ability to make independent, analytical inquiries, collegiality, willingness and ability to devote the time required to perform Board activities adequately, ability to represent the interests of all shareholders of the Registrant, and diversity relative to the board's composition. Candidates are expected to provide a mix of attributes, experience, perspective and skills necessary to effectively advance the interests of shareholders. ITEM 10.
