BELOW IS A DISCUSSION BY OPPENHEIMERFUNDS, INC., OF THE FUND'S PERFORMANCE DURING ITS FISCAL YEAR ENDED JULY 31, 2006, 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, 2006, Oppenheimer Main Street Opportunity Fund produced total returns that were greater than that of its benchmark, the Russell 3000 Index, and higher than the average return of the funds reported in its peer group, the Lipper Multi-Cap Core category. We attribute the Fund's strong relative performance to the success of our market-capitalization allocation and security selection strategies. From a market capitalization standpoint, the Fund began the reporting period with an emphasis on stocks at the larger end of the capitalization range and a corresponding de-emphasis on smaller-cap stocks. This position reflected results from our statistical models suggesting that the cycle of small-cap outperformance that began in 1999 was likely to come to an end. While this positioning proved to be relatively costly over much of the reporting period, when smaller, lower-quality stocks continued to outperform their larger counterparts, it positioned the Fund well for the shift in investor sentiment that began in May 2006. The Fund's emphasis on larger stocks enabled it to weather the ensuing market correction better than its benchmark, offsetting earlier allocation-related weakness and contributing positively to the Fund's performance for the reporting period overall. The Fund's stock selection strategy produced higher returns than the benchmark in nine of the ten economic sectors represented in the Russell 3000 Index. Only the telecommunications services areas detracted mildly from the Fund's relative performance. Our sector allocation decisions were especially successful in the energy and consumer discretionary sectors. An overweighted position in the energy sector helped the Fund participate more fully in its gains, while relatively light exposure to consumer discretionary stocks sheltered the Fund from the full brunt of weakness in that sector. Finally, it is worth noting that although the Fund remains very well diversified, the number of stocks in the Fund's portfolio has declined from 834 at the start of the reporting period to 496 at the end. This reflects the Fund's sale of a number of micro-, small- and mid-cap issues as we increased the proportion of assets invested in large- and mega-cap stocks. 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, 2006. 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 10 | OPPENHEIMER MAIN STREET OPPORTUNITY FUND 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. 11 | OPPENHEIMER MAIN STREET OPPORTUNITY FUND FUND PERFORMANCE DISCUSSION -------------------------------------------------------------------------------- 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 CHART IN THE PRINTED MATERIAL.] Oppenheimer Main Street Opportunity Fund(R) Russell 3000 (Class A) 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 10/31/2004 $12,383 $ 8,557 01/31/2005 $13,062 $ 9,027 04/30/2005 $12,816 $ 8,873 07/31/2005 $13,901 $ 9,654 10/31/2005 $13,758 $ 9,465 01/31/2006 $14,902 $10,171 04/30/2006 $15,360 $10,477 07/31/2006 $14,945 $10,150 AVERAGE ANNUAL TOTAL RETURNS OF CLASS A SHARES WITH SALES CHARGE OF THE FUND AT 7/31/06 1-Year 1.33% 5-Year 7.36% Since Inception (9/25/00) 7.11% 12 | OPPENHEIMER MAIN STREET OPPORTUNITY FUND 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 [THE FOLLOWING TABLE WAS REPRESENTED BY A LINE CHART IN THE PRINTED MATERIAL.] Oppenheimer Main Street Opportunity Fund(R) Russell 3000 (Class B) 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 $10,470 $ 7,288 10/31/2003 $11,670 $ 7,815 01/31/2004 $12,760 $ 8,457 04/30/2004 $12,360 $ 8,294 07/31/2004 $12,310 $ 8,258 10/31/2004 $12,720 $ 8,557 01/31/2005 $13,378 $ 9,027 04/30/2005 $13,107 $ 8,873 07/31/2005 $14,178 $ 9,654 10/31/2005 $14,016 $ 9,465 01/31/2006 $15,142 $10,171 04/30/2006 $15,578 $10,477 07/31/2006 $15,019 $10,150 AVERAGE ANNUAL TOTAL RETURNS OF CLASS B SHARES WITH SALES CHARGE OF THE FUND AT 7/31/06 1-Year 1.64% 5-Year 7.47% Since Inception (9/25/00) 7.20% 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. 17 | OPPENHEIMER MAIN STREET OPPORTUNITY FUND 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 July 31, 2006. 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 18 | OPPENHEIMER MAIN STREET OPPORTUNITY FUND 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.

SEE ACCOMPANYING NOTES TO FINANCIAL STATEMENTS. 41 | 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 may be valued primarily using dealer-supplied valuations or a portfolio pricing service authorized by the Board of Trustees. Securities listed or traded on National Stock Exchanges or other domestic 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 traded on foreign exchanges are valued based on the last sale price on the principal exchange on which the security is traded, as identified by the portfolio pricing service, prior to the time when the Fund's assets are valued. In the absence of a sale, the security is valued at the official closing price on the principal exchange. Corporate, government and municipal debt instruments having a remaining maturity in excess of sixty days and all mortgage-backed securities will be valued at the mean between the "bid" and "asked" prices. Futures contracts traded on a commodities or futures exchange will be valued at the final settlement price or official closing price on the principal exchange as reported by such principal exchange at its 42 | OPPENHEIMER MAIN STREET OPPORTUNITY FUND trading session ending at, or most recently prior to, the time when the Fund's assets are valued. 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). -------------------------------------------------------------------------------- FOREIGN CURRENCY TRANSLATION. The Fund's accounting records are maintained in U.S. dollars. The values of securities denominated in foreign currencies and amounts related to the purchase and sale of foreign securities and foreign investment income 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. 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. 43 | OPPENHEIMER MAIN STREET OPPORTUNITY FUND NOTES TO FINANCIAL STATEMENTS Continued -------------------------------------------------------------------------------- 1. SIGNIFICANT ACCOUNTING POLICIES Continued 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. 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 -------------------------------------------------------------------------- $69,225,526 $57,883,739 $-- $322,497,609 1. During the fiscal year ended July 31, 2006, the Fund did not utilize any capital loss carryforward. 2. During the fiscal year ended July 31, 2005, 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, 2006. Net assets of the Fund were unaffected by the reclassifications.

The tax character of distributions paid during the years ended July 31, 2006 and July 31, 2005 was as follows: YEAR ENDED YEAR ENDED JULY 31, 2006 JULY 31, 2005 ------------------------------------------------------------------- Distributions paid from: Ordinary income $ 52,090,254 $ 56,154,423 Long-term capital gain 62,412,943 124,619,088 ----------------------------------- Total $ 114,503,197 $ 180,773,511 =================================== 44 | OPPENHEIMER MAIN STREET OPPORTUNITY FUND 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, 2006 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 $ 3,228,683,227 Federal tax cost of other investments (1,281,188) --------------- Total federal tax cost $ 3,227,402,039 =============== Gross unrealized appreciation $ 391,522,404 Gross unrealized depreciation (69,024,795) --------------- Net unrealized appreciation $ 322,497,609 =============== -------------------------------------------------------------------------------- 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 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. -------------------------------------------------------------------------------- CUSTODIAN FEES. "Custodian fees and expenses" in the Statement of Operations may include interest expense incurred by the Fund on any cash overdrafts of its custodian account during the period. Such cash overdrafts may result from the effects of failed trades in portfolio securities and from cash outflows resulting from unanticipated shareholder redemption activity. The Fund pays interest to its custodian on such cash overdrafts, to the extent they are not offset by positive cash balances maintained by the Fund, at a rate equal to the Federal Funds Rate plus 0.50%. The "Reduction to custodian 45 | OPPENHEIMER MAIN STREET OPPORTUNITY FUND NOTES TO FINANCIAL STATEMENTS Continued -------------------------------------------------------------------------------- -------------------------------------------------------------------------------- 1. SIGNIFICANT ACCOUNTING POLICIES Continued expenses" line item, if applicable, represents earnings on cash balances maintained by the Fund during the period. Such interest expense and other custodian fees may be paid with these earnings. -------------------------------------------------------------------------------- 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. -------------------------------------------------------------------------------- INDEMNIFICATIONS. The Fund's organizational documents provide current and former trustees and officers with a limited indemnification against liabilities arising in connection with the performance of their duties to the Fund. In the normal course of business, the Fund may also enter into contracts that provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against the Fund. The risk of material loss from such claims is considered remote. -------------------------------------------------------------------------------- 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. SHARES OF BENEFICIAL INTEREST The Fund has authorized an unlimited number of $0.001 par value shares of beneficial interest of each class. Transactions in shares of beneficial interest were as follows:

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 47 | OPPENHEIMER MAIN STREET OPPORTUNITY FUND NOTES TO FINANCIAL STATEMENTS Continued -------------------------------------------------------------------------------- -------------------------------------------------------------------------------- 4. FEES AND OTHER TRANSACTIONS WITH AFFILIATES Continued account fee. For the year ended July 31, 2006, the Fund paid $5,859,519 to OFS for services to the Fund. Additionally, Class Y shares are subject to minimum fees of $10,000 per annum for assets of $10 million or more. The Class Y shares are subject to the minimum fees in the event that the 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 periodically 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 periodically 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 periods. 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% on Class B and Class C shares and 0.25% on Class N shares. The Distributor also receives a service fee of 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, 2006 for Class B, Class C and Class N shares were $5,931,247, $5,255,295 and $1,163,144, respectively. Fees incurred by the Fund under the plans are detailed in the Statement of Operations. -------------------------------------------------------------------------------- SALES CHARGES. Front-end sales charges and contingent deferred sales charges (CDSC) do not represent expenses of the Fund. They are deducted from the proceeds of sales of Fund shares prior to investment or from redemption proceeds prior to remittance, as applicable. The sales charges retained by the Distributor from the sale of shares and the CDSC retained by the Distributor on the redemption of shares is shown in the following table for the period indicated. 48 | OPPENHEIMER MAIN STREET OPPORTUNITY FUND

OFS has voluntarily agreed to limit transfer and shareholder servicing agent fees for all classes to 0.35% of average annual net assets per class. 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, 2006, the Fund had outstanding foreign currency contracts as follows:

ILLIQUID OR RESTRICTED SECURITIES As of July 31, 2006, 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 49 | OPPENHEIMER MAIN STREET OPPORTUNITY FUND NOTES TO FINANCIAL STATEMENTS Continued -------------------------------------------------------------------------------- -------------------------------------------------------------------------------- 6. ILLIQUID OR RESTRICTED SECURITIES Continued 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.

-------------------------------------------------------------------------------- 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 securities, letters of credit 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 each day. If the Fund is undercollateralized at the close of business due to an increase in market value of securities on loan, additional collateral is requested from the borrowing counterparty and is delivered to the Fund on the next business day. Cash collateral may be invested in approved investments and the Fund bears the risk of any loss in value of these investments. The Fund retains a portion of the interest earned from the collateral. 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. The Fund continues to receive the economic benefit of interest or dividends paid on the securities loaned in the form of a substitute payment received from the borrower. As of July 31, 2006, the Fund had on loan securities valued at $8,716,546 , which are included in the Statement of Assets and Liabilities as "Investments, at value" and, when applicable, as "Investments sold." Collateral of $9,228,200 was received for the loans, all of which was received in cash and subsequently invested in approved investments or held as cash. -------------------------------------------------------------------------------- 8. RECENT ACCOUNTING PRONOUNCEMENT In June 2006, the Financial Accounting Standards Board ("FASB") issued FASB Interpretation No. 48 ("FIN 48"), ACCOUNTING FOR UNCERTAINTY IN INCOME TAXES. FIN 48 clarifies the accounting for uncertainty in income taxes recognized in an enterprise's financial statements in accordance with FASB Statement No. 109, Accounting for Income Taxes. FIN 48 requires the evaluation of tax positions taken in the course of preparing the Fund's tax returns to determine whether it is "more-likely-than-not" that tax positions taken in the Fund's tax return will be ultimately sustained. A tax liability and expense 50 | OPPENHEIMER MAIN STREET OPPORTUNITY FUND must be recorded in respect of any tax position that, in Management's judgment, will not be fully realized. FIN 48 is effective for fiscal years beginning after December 15, 2006. As of July 31, 2006, the Manager is evaluating the implications of FIN 48. Its impact in the Fund's financial statements has not yet been determined. -------------------------------------------------------------------------------- 9. LITIGATION A consolidated amended complaint was filed as a putative class action against the Manager and the Transfer Agent and other defendants (including 51 of the Oppenheimer funds including the Fund) in the U.S. District Court for the Southern District of New York on January 10, 2005 and was amended on March 4, 2005. The complaint alleged, among other things, that the Manager charged excessive fees for distribution and other costs, and that by permitting and/or participating in those actions, the Directors/Trustees and the Officers of the funds breached their fiduciary duties to fund shareholders under the Investment Company Act of 1940 and at common law. The plaintiffs sought unspecified damages, an accounting of all fees paid, and an award of attorneys' fees and litigation expenses. In response to the defendants' motions to dismiss the suit, seven of the eight counts in the complaint, including the claims against certain of the Oppenheimer funds, as nominal defendants, and against certain present and former Directors, Trustees and Officers of the funds, and the Distributor, as defendants, were dismissed with prejudice, by court order dated March 10, 2006, and the remaining count against the Manager and the Transfer Agent was dismissed with prejudice by court order dated April 5, 2006. The plaintiffs filed an appeal of those dismissals on May 11, 2006. The Manager believes that the allegations contained in the complaint are without merit and that there are substantial grounds to sustain the district court's rulings. The Manager also believes that it is premature to render any opinion as to the likelihood of an outcome unfavorable to it, the funds, the Directors/Trustees or the Officers on the appeal of the decisions of the district court, and that no estimate can yet be made with any degree of certainty as to the amount or range of any potential loss. 51 | 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, 2006, 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. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audit includes consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of July 31, 2006, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures.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, 2006, 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 accounting principles generally accepted in the United States of America. DELOITTE & TOUCHE LLP Denver, Colorado September 14, 2006 52 | OPPENHEIMER MAIN STREET OPPORTUNITY FUND FEDERAL INCOME TAX INFORMATION Unaudited -------------------------------------------------------------------------------- -------------------------------------------------------------------------------- In early 2007, if applicable, shareholders of record will receive information regarding all dividends and distributions paid to them by the Fund during calendar year 2006. Regulations of the U.S. Treasury Department require the Fund to report this information to the Internal Revenue Service. Capital gain distributions of $0.2827 per share were paid to Class A, Class B, Class C, Class N and Class Y shareholders, respectively, on December 9, 2005. Whether received in stock or in cash, the capital gain distribution should be treated by shareholders as a gain from the sale of the capital assets held for more than one year (long-term capital gains). Dividends, if any, paid by the Fund during the fiscal year ended July 31, 2006 which are not designated as capital gain distributions should be multiplied by 41.33% 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, 2006 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. $51,872,981 of the Fund's fiscal year taxable income may be eligible for the lower individual income tax rates. In early 2007, shareholders of record will receive information regarding the percentage of distributions that are eligible for lower individual income tax rates. Recent tax legislation allows a regulated investment company to designate distributions not designated as capital gain distributions, as either interest related dividends or short-term capital gain dividends, both of which are exempt from the U.S. withholding tax applicable to non U.S. taxpayers. For the fiscal year ended July 31, 2006, $440,714 or 3.89% of the ordinary distributions paid by the Fund qualifies as an interest related dividend and $106,584,520 or 100% of the short-term capital gain distribution paid by the Fund qualifies as a short-term capital gain dividend. 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. 53 | OPPENHEIMER MAIN STREET OPPORTUNITY FUND PORTFOLIO PROXY VOTING POLICIES AND PROCEDURES; UPDATES TO STATEMENTS OF INVESTMENTS 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.

In evaluating trustee nominees, the Committee considers, among other things, an individual's background, skills, and experience; whether the individual is an "interested person" as defined in the Investment Company Act of 1940; and whether the individual would be deemed an "audit committee financial expert" within the meaning of applicable SEC rules. The Committee also considers whether the individual's background, skills, and experience will complement the background, skills, and experience of other nominees and will contribute to the Board. There are no differences in the manner in which the Committee evaluates nominees for trustees based on whether the nominee is recommended by a shareholder. 3. The Committee may consider nominations from shareholders for the Board at such times as the Committee meets to consider new nominees for the Board. The Committee shall have the sole discretion to determine the candidates to present to the Board and, in such cases where required, to shareholders. Recommendations for trustee nominees should, at a minimum, be accompanied by the following: o the name, address, and business, educational, and/or other pertinent background of the person being recommended; o a statement concerning whether the person is an "interested person" as defined in the Investment Company Act of 1940; o any other information that the Funds would be required to include in a proxy statement concerning the person if he or she was nominated; and o the name and address of the person submitting the recommendation and, if that person is a shareholder, the period for which that person held Fund shares. The recommendation also can include any additional information which the person submitting it believes would assist the Committee in evaluating the recommendation. 4. Shareholders should note that a person who owns securities issued by Massachusetts Mutual Life Insurance Company (the parent company of the Funds' investment adviser) would be deemed an "interested person" under the Investment Company Act of 1940. In addition, certain other relationships with Massachusetts Mutual Life Insurance Company or its subsidiaries, with registered broker-dealers, or with the Funds' outside legal counsel may cause a person to be deemed an "interested person." 5. Before the Committee decides to nominate an individual as a trustee, Committee members and other directors customarily interview the individual in person. In addition, the individual customarily is asked to complete a detailed questionnaire which is designed to elicit information which must be disclosed under SEC and stock exchange rules and to determine whether the individual is subject to any statutory disqualification from serving as a trustee of a registered investment company.
