BELOW IS A DISCUSSION BY OPPENHEIMERFUNDS, INC., OF THE FUND'S PERFORMANCE DURING ITS FISCAL YEAR ENDED AUGUST 31, 2005, FOLLOWED BY A GRAPHICAL COMPARISON OF THE FUND'S PERFORMANCE TO AN APPROPRIATE BROAD-BASED MARKET INDEX. MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE. During its fiscal year ended August 31, 2005, Oppenheimer Main Street Fund produced slightly lower returns than its benchmark, the S&P 500 Index. We attribute the Fund's relative performance primarily to its focus on mega-cap stocks during a time in which large-, mid- and small-cap stocks provided higher returns. In March 2004, before the start of the reporting period, the Fund's quantitative models began to indicate that the cycle of small-cap outperformance that began in 1999 would probably end. Therefore, we gradually increased the Fund's weighted average market capitalization from $85.1 billion on February 28, 2004 to $112.2 billion as of November 30, 2004, an increase of 32%. Much of this increase was achieved through greater emphasis on mega-cap stocks. However, smaller stocks produced better performance, and the Fund's emphasis on mega-cap stocks detracted from its relative performance early in the reporting period. We subsequently reduced the Fund's weighted average market capitalization in anticipation of seasonal factors that tend to favor smaller stocks. However, instead of increasing the Fund's weighted average market capitalization to its previous level after these seasonal factors ran their course, we continued to move gradually toward a more moderate position. By the end of July, the Fund's weighted average market capitalization had fallen to $96.4 billion. This reduction did not represent a change in strategy; rather, we shifted some assets from the mega-cap category to the large-cap category in order to achieve a better balance relative to the benchmark. Weakness related to the Fund's larger weighted average market capitalization early in the reporting period was partially offset by stronger results from the Fund's security selection strategy in 2005. Of the Fund's top 10 contributions to positive performance for the reporting period, six were energy companies that benefited from higher oil and gas prices. The Fund also received positive contributions from the consumer discretionary sector, where we focused on retailers and de-emphasized lagging media companies. Conversely, the health care and financials area detracted modestly from the Fund's relative performance: Of the Fund's bottom 10 performers for the reporting period, five were health care or financial companies that had been the subjects of negative headlines. As of the end of the reporting period, our quantitative process has found a larger number of opportunities in the energy and financials sectors, but relatively few in the 10 | OPPENHEIMER MAIN STREET FUND consumer discretionary, information technology and industrials areas. In addition, the fund remains broadly diversified, with approximately 525 holdings as of August 31, 2005. COMPARING THE FUND'S PERFORMANCE TO THE MARKET. The graphs that follow show the performance of a hypothetical $10,000 investment in each class of shares of the Fund held until August 31, 2005. In the case of Class A, Class B, and Class C shares, performance is measured over a ten-fiscal-year period. In the case of Class N shares, performance is measured from inception of the class on March 1, 2001. In the case of Class Y shares, performance is measured from inception of the class on November 1, 1996. 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 S&P 500 Index. The S&P 500 Index is an unmanaged index of equity securities. 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 FUND FUND PERFORMANCE DISCUSSION - -------------------------------------------------------------------------------- CLASS A SHARES COMPARISON OF CHANGE IN VALUE OF $10,000 HYPOTHETICAL INVESTMENTS IN: Oppenheimer Main Street Fund(R)(Class A) S&P 500 Index [THE FOLLOWING TABLE WAS REPRESENTED BY A LINE CHART IN THE PRINTED MATERIAL.] Oppenheimer Main Street S&P 500 Index Fund(R)(Class A) 06/30/1995 9,425 10,000 09/30/1995 10,248 10,794 12/31/1995 10,651 11,443 03/31/1996 11,249 12,058 06/30/1996 11,523 12,598 08/31/1996 1 11,148 12,296 11/30/1996 12,560 14,353 02/28/1997 12,996 15,065 05/31/1997 13,722 16,245 08/31/1997 14,614 17,291 11/30/1997 15,289 18,445 02/28/1998 16,515 20,336 05/31/1998 17,427 21,225 08/31/1998 15,151 18,696 11/30/1998 18,132 22,813 02/28/1999 19,260 24,354 05/31/1999 20,366 25,689 08/31/1999 21,003 26,138 11/30/1999 21,532 27,579 02/29/2000 21,642 27,210 05/31/2000 22,802 28,378 08/31/2000 24,730 30,400 11/30/2000 20,597 26,414 02/28/2001 19,849 24,980 05/31/2001 20,398 25,385 08/31/2001 18,583 22,990 11/30/2001 18,531 23,188 02/28/2002 18,390 22,606 05/31/2002 18,419 21,873 08/31/2002 16,186 18,855 11/30/2002 15,994 19,360 02/28/2003 14,585 17,480 05/31/2003 16,601 20,108 08/31/2003 17,308 21,128 11/30/2003 18,494 22,280 02/29/2004 19,922 24,210 05/31/2004 19,475 23,792 08/31/2004 19,275 23,546 11/30/2004 20,357 25,142 02/28/2005 21,032 25,897 05/31/2005 20,890 25,750 08/31/2005 21,526 26,502 AVERAGE ANNUAL TOTAL RETURNS OF CLASS A SHARES WITH SALES CHARGE OF THE FUND AT 8/31/05 1-Year 5.26% 5-Year -3.88% 10-Year 7.37% 12 | OPPENHEIMER MAIN STREET FUND CLASS B SHARES COMPARISON OF CHANGE IN VALUE OF $10,000 HYPOTHETICAL INVESTMENTS IN: Oppenheimer Main Street Fund(R) (Class B) S&P 500 Index [THE FOLLOWING TABLE WAS REPRESENTED BY A LINE CHART IN THE PRINTED MATERIAL.] Oppenheimer Main Street S&P 500 Index Fund(R)(Class B) 06/30/1995 10,000 10,000 09/30/1995 10,850 10,794 12/31/1995 11,256 11,443 03/31/1996 11,867 12,058 06/30/1996 12,134 12,598 08/31/1996 1 11,721 12,296 11/30/1996 13,183 14,353 02/28/1997 13,613 15,065 05/31/1997 14,348 16,245 08/31/1997 15,251 17,291 11/30/1997 15,927 18,445 02/28/1998 17,170 20,336 05/31/1998 18,080 21,225 08/31/1998 15,688 18,696 11/30/1998 18,745 22,813 02/28/1999 19,874 24,354 05/31/1999 20,973 25,689 08/31/1999 21,589 26,138 11/30/1999 22,093 27,579 02/29/2000 22,157 27,210 05/31/2000 23,302 28,378 08/31/2000 25,224 30,400 11/30/2000 20,967 26,414 02/28/2001 20,176 24,980 05/31/2001 20,692 25,385 08/31/2001 18,847 22,990 11/30/2001 18,794 23,188 02/28/2002 18,651 22,606 05/31/2002 18,680 21,873 08/31/2002 16,415 18,855 11/30/2002 16,221 19,360 02/28/2003 14,792 17,480 05/31/2003 16,836 20,108 08/31/2003 17,553 21,128 11/30/2003 18,756 22,280 02/29/2004 20,205 24,210 05/31/2004 19,751 23,792 08/31/2004 19,549 23,546 11/30/2004 20,646 25,142 02/28/2005 21,331 25,897 05/31/2005 21,186 25,750 08/31/2005 21,832 26,502 AVERAGE ANNUAL TOTAL RETURNS OF CLASS B SHARES WITH SALES CHARGE OF THE FUND AT 8/31/05 1-Year 5.79% 5-Year -3.87% 10-Year 7.52% THE PERFORMANCE DATA QUOTED REPRESENTS PAST PERFORMANCE, WHICH DOES NOT GUARANTEE FUTURE RESULTS.

The Fund's prospectus contains this and other information about the Fund, and may be obtained by asking your financial advisor, calling us at 1.800.525.7048 or visiting our website at www.oppenheimerfunds.com. Read the prospectus carefully before investing. The Fund's investment strategy and focus can change over time. The mention of specific fund holdings does not constitute a recommendation by OppenheimerFunds, Inc. CLASS A shares of the Fund were first publicly offered on 2/3/88. Class A returns include the current maximum initial sales charge of 5.75%. CLASS B shares of the Fund were first publicly offered on 10/3/94. Class B returns include the applicable contingent deferred sales charge of 5% (1-year) and 2% (5-year). Because Class B shares convert to Class A shares 72 months after purchase, the 10-year return for Class B uses Class A performance for the period after conversion. Class B shares are subject to an annual 0.75% asset-based sales charge. CLASS C shares of the Fund were first publicly offered on 12/1/93. Class C returns include the contingent deferred sales charge of 1% for the 1-year period. Class C shares are subject to an annual 0.75% asset-based sales charge. CLASS N shares of the Fund were first publicly offered on 3/1/01. Class N shares are offered only through retirement plans. Unless otherwise noted, Class N returns include the contingent deferred sales charge of 1% for the 1-year period. Class N shares are subject to an annual 0.25% asset-based sales charge. 17 | OPPENHEIMER MAIN STREET FUND NOTES - -------------------------------------------------------------------------------- CLASS Y shares of the Fund were first publicly offered on 11/1/96. Class Y shares are offered only to certain institutional investors under special agreements with the Distributor. An explanation of the calculation of performance is in the Fund's Statement of Additional Information. 18 | OPPENHEIMER MAIN STREET 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 August 31, 2005. 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 19 | OPPENHEIMER MAIN STREET 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. - -------------------------------------------------------------------------------- BEGINNING ENDING EXPENSES ACCOUNT ACCOUNT PAID DURING VALUE VALUE 6 MONTHS ENDED (3/1/05) (8/31/05) AUGUST 31, 2005 - -------------------------------------------------------------------------------- Class A Actual $1,000.00 $1,023.50 $4.70 - -------------------------------------------------------------------------------- Class A Hypothetical 1,000.00 1,020.57 4.70 - -------------------------------------------------------------------------------- Class B Actual 1,000.00 1,019.50 8.69 - -------------------------------------------------------------------------------- Class B Hypothetical 1,000.00 1,016.64 8.68 - -------------------------------------------------------------------------------- Class C Actual 1,000.00 1,019.80 8.49 - -------------------------------------------------------------------------------- Class C Hypothetical 1,000.00 1,016.84 8.47 - -------------------------------------------------------------------------------- Class N Actual 1,000.00 1,021.70 6.44 - -------------------------------------------------------------------------------- Class N Hypothetical 1,000.00 1,018.85 6.43 - -------------------------------------------------------------------------------- Class Y Actual 1,000.00 1,026.00 2.51 - -------------------------------------------------------------------------------- Class Y Hypothetical 1,000.00 1,022.74 2.50 Hypothetical assumes 5% annual return before expenses. Expenses are equal to the Fund's annualized expense ratio for that class, multiplied by the average account value over the period, multiplied by 184/365 (to reflect the one-half year period).

SIGNIFICANT ACCOUNTING POLICIES Oppenheimer Main Street Fund (the Fund) is a separate series of Oppenheimer Main Street Funds, Inc., an open-end management investment company registered under the Investment Company Act of 1940, as amended. The Fund's investment objective is to seek a high total return. 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 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, in the country that is 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 trading session ending at, or most recently prior to, the time when the Fund's assets are valued. Securities may be valued primarily 43 | OPPENHEIMER MAIN STREET FUND NOTES TO FINANCIAL STATEMENTS Continued - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 1. SIGNIFICANT ACCOUNTING POLICIES Continued using dealer-supplied valuations or a portfolio pricing service authorized by the Board of Directors. 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 Directors. 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 Directors. 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 44 | OPPENHEIMER MAIN STREET FUND 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. 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 1,2,3 TAX PURPOSES --------------------------------------------------------------------------- $66,708,960 $-- $669,112,569 $2,048,256,170 1. As of August 31, 2005, the Fund had $669,112,569 of net capital loss carryforwards available to offset future realized capital gains, if any, and thereby reduce future taxable gain distributions. As of August 31, 2005, details of the capital loss carryforward were as follows: EXPIRING ----------------------------- 2011 $669,112,569 2. During the fiscal year ended August 31, 2005, the Fund utilized $557,605,412 of capital loss carryforward to offset capital gains realized in that fiscal year. a a. Includes $489,935 of capital loss carryforwards acquired in the September 4, 2003 merger of Oppenheimer Trinity Core Fund. 3. During the fiscal year ended August 31, 2004, the Fund utilized $941,293,880 of capital loss carryforward to offset capital gains realized in that fiscal year. b b. Includes $485,908 of capital loss carryforwards acquired in the September 4, 2003 merger of Oppenheimer Trinity Core 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 August 31, 2005. Net assets of the Fund were unaffected by the reclassifications.

SIGNIFICANT ACCOUNTING POLICIES Continued The tax character of distributions paid during the years ended August 31, 2005 and August 31, 2004 was as follows: YEAR ENDED YEAR ENDED AUGUST 31, 2005 AUGUST 31, 2004 ---------------------------------------------------------------- Distributions paid from: Ordinary income $116,737,394 $52,898,285 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 August 31, 2005 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 $9,564,994,238 Federal tax cost of other investments (39,358) --------------- Total federal tax cost $9,564,954,880 =============== Gross unrealized appreciation $2,207,793,783 Gross unrealized depreciation (159,537,613) --------------- Net unrealized appreciation $2,048,256,170 =============== - -------------------------------------------------------------------------------- DIRECTORS' COMPENSATION. The Board of Directors has adopted a deferred compensation plan for independent directors that enables directors 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 Director 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 Director. The Fund purchases shares of the funds selected for deferral by the Director 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 directors' 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.

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 at a rate equal to the Federal Funds Rate plus 0.50%. The Reduction to Custodian Expenses line item, if applicable, represents earnings on cash balances maintained by the Fund during the period.

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.

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 August 31, 2005, the Fund had outstanding foreign currency contracts as follows: CONTRACT VALUATION AS OF EXPIRATION AMOUNT AUGUST 31, UNREALIZED CONTRACT DESCRIPTION DATE (000S) 2005 DEPRECIATION - ------------------------------------------------------------------------------------------- CONTRACTS TO SELL Canadian Dollar [CAD] 9/1/05 47CAD $39,358 $221 - -------------------------------------------------------------------------------- 6. ILLIQUID SECURITIES As of August 31, 2005, investments in securities included issues that are illiquid. A security may be considered illiquid if it lacks a readily available market or if its valuation has not changed for a certain period of time. The Fund will not invest more than 10% of its net assets (determined at the time of purchase and reviewed periodically) in illiquid securities. Securities that are illiquid are marked with the applicable footnote on the Statement of Investments. 50 | OPPENHEIMER MAIN STREET FUND - -------------------------------------------------------------------------------- 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 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 August 31, 2005, the Fund had on loan securities valued at $11,027,306. Collateral of $11,092,279 was received for the loans, all of which was received in cash and subsequently invested in approved instruments. - -------------------------------------------------------------------------------- 8.

LITIGATION A consolidated amended complaint has been filed as putative derivative and class actions against the Manager, OFS and the Distributor, as well as 51 of the Oppenheimer funds (as "Nominal Defendants") including the Fund, 30 present and former Directors or Trustees and 8 present and former officers of the funds. This complaint, initially filed in the U.S. District Court for the Southern District of New York on January 10, 2005 and amended on March 4, 2005, consolidates into a single action and amends six individual previously-filed putative derivative and class action complaints. Like those prior complaints, the complaint alleges 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 assets of the funds to make those payments in violation of the Investment Company Act of 1940 and the Investment Advisers Act of 1940. Also, like those prior complaints, the complaint further alleges that by permitting and/or participating in those actions, the Directors/Trustees and the Officers breached their fiduciary duties to shareholders of the funds under the Investment Company Act of 1940 and at common law. The complaint seeks unspecified compensatory and punitive damages, rescission of the funds' investment advisory agreements, an accounting of all fees paid, and an award of attorneys' fees and litigation expenses. The defendants believe that the allegations contained in the Complaints are without merit and that they have meritorious defenses against the claims asserted. The defendants intend to defend these lawsuits vigorously and to contest any claimed liability. The defendants believe that it is premature to render any opinion as to the likelihood of an outcome unfavorable to them and that no estimate can yet be made with any degree of certainty as to the amount or range of any potential loss. 52 | OPPENHEIMER MAIN STREET FUND REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- TO THE BOARD OF DIRECTORS AND SHAREHOLDERS OF OPPENHEIMER MAIN STREET FUND: We have audited the accompanying statement of assets and liabilities of Oppenheimer Main Street Fund, a series of Oppenheimer Main Street Funds, Inc., including the statement of investments, as of August 31, 2005, 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 August 31, 2005, 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 Fund as of August 31, 2005, 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 October 17, 2005 53 | OPPENHEIMER MAIN STREET FUND FEDERAL INCOME TAX INFORMATION Unaudited - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- In early 2006, if applicable, shareholders of record will receive information regarding all dividends and distributions paid to them by the Fund during calendar year 2005. Regulations of the U.S. Treasury Department require the Fund to report this information to the Internal Revenue Service. Dividends of $0.4118, $0.0924, $0.1597, $0.3281 and $0.5285 per share were paid to Class A, Class B, Class C, Class N and Class Y shareholders, respectively, on December 3, 2004, none of which was designated as a "capital gain distribution" for federal income tax purposes. Dividends, if any, paid by the Fund during the fiscal year ended August 31, 2005 which are not designated as capital gain distributions should be multiplied by 100% 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 August 31, 2005 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. $261,552,326 of the Fund's fiscal year taxable income may be eligible for the lower individual income tax rates. In early 2006, 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. 54 | OPPENHEIMER MAIN STREET 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.

Information on the operation of the Public Reference Room may be obtained by calling 1-800-SEC-0330. 55 | OPPENHEIMER MAIN STREET FUND BOARD APPROVAL OF THE FUND'S INVESTMENT ADVISORY AGREEMENT Unaudited - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- Each year, the Board of Directors (the "Board"), including a majority of the independent Directors, is required to determine whether to renew the Fund's advisory agreement. The Investment Company Act of 1940, as amended, requires that the Board request and evaluate, and that the Manager provide, such information as may be reasonably necessary to evaluate the terms of the advisory agreement. The Board employs an independent consultant to prepare a report that provides information, including comparative information, that the Board requests for this purpose. In addition, the Board receives information throughout the year regarding Fund services, fees, expenses and performance. NATURE AND EXTENT OF SERVICES. In considering the renewal of the Fund's advisory agreement for the current year, the Board evaluated the nature and extent of the services provided by the Manager and its affiliates. The Manager provides the Fund with office space, facilities and equipment; administrative, accounting, clerical, legal and compliance personnel; securities trading services; oversight of third party service providers and the services of the portfolio managers and the Manager's investment team, who provide research, analysis and other advisory services in regard to the Fund's investments. QUALITY OF SERVICES. The Board also considered the quality of the services provided and the quality of the Manager's resources that were available to the Fund. The Board noted that the Manager has had over forty years of experience as an investment adviser and that its assets under management rank it among the top mutual fund managers in the United States. The Board evaluated the Manager's administrative, accounting, legal and compliance services and information the Board received regarding the experience and professional qualifications of the Manager's personnel and the size and functions of its staff. The Board members also considered their experiences as directors or trustees of the Fund and other funds advised by the Manager. The Board received and reviewed information regarding the quality of services provided by affiliates of the Manager, which it also reviews at other times during the year in connection with the renewal of the Fund's service agreements. The Board was aware that there are alternatives to retaining the Manager. PORTFOLIO MANAGEMENT SERVICES AND PERFORMANCE. In its evaluation of the quality of the portfolio management services to be provided, the Board considered the experience of Nikolaos Monoyios and Marc Reinganum and the Manager's Equity Growth investment team and analysts. Mr. Monoyios and Mr. Reinganum have been primarily responsible for the day-to-day management of the Fund's investments since April 1998 and October 2003, respectively. Mr. Monoyios is a Certified Financial Analyst and a Senior Vice President of the Manager and a Vice President of the Fund. Mr. Reinganum is a Vice President of the Fund and of the Manager. Mr. Monoyios has had over 27 years 56 | OPPENHEIMER MAIN STREET FUND of experience and Mr. Reinganum has had over 25 years of experience managing equity investments and they are both portfolio managers and officers of other portfolios in the OppenheimerFunds complex. The Board also reviewed information, prepared by the Manager and by the independent consultant, comparing the Fund's historical performance to relevant market indices and to the performance of other large-cap core funds advised by other investment advisers. The Board also receives and reviews comparative performance information regarding the Fund and other funds at each Board meeting. The Board noted that the Fund's one-year, three-year and five-year performance were all better than its peer group average. However, its ten-year performance was below its peer group average. MANAGEMENT FEES AND EXPENSES. The Board also reviewed information, including comparative information, regarding the fees paid to the Manager and its affiliates and the other expenses borne by the Fund. The independent consultant provided comparative data in regard to the fees and expenses of the Fund and other large-cap core funds with comparable asset levels and distribution features. The Board noted that the Fund's contractual and actual management fees and its total expenses are all lower than its peer group average. In addition, the Board evaluated the comparability of the fees charged and the services provided to the Fund to the fees charged and services provided to other types of entities advised by the Manager. PROFITABILITY OF THE MANAGER AND AFFILIATES. The Board also reviewed information regarding the cost of services provided by the Manager and its affiliates and the Manager's profitability. The Board considered that the Manager must be able to pay and retain experienced professional personnel at competitive rates to provide services to the Fund and that maintaining the financial viability of the Manager is important in order for the Manager to continue to provide significant services to the Fund and its shareholders. In addition the Board considered information that was provided regarding the direct and indirect benefits the Manager receives as a result of its relationship with the Fund, including compensation paid to the Manager's affiliates and research provided to the Manager in connection with permissible brokerage arrangements (soft dollar arrangements). ECONOMIES OF SCALE. The Board reviewed the extent to which the Manager may realize economies of scale in managing and supporting the Fund and the current level of Fund assets in relation to the Fund's breakpoint schedule for its management fees. The Board considered that the Fund has recently experienced moderate asset growth and that, based on current asset levels, the Fund has passed its last management fee breakpoint. 57 | OPPENHEIMER MAIN STREET FUND BOARD APPROVAL OF THE FUND'S INVESTMENT ADVISORY AGREEMENT Unaudited / Continued - -------------------------------------------------------------------------------- CONCLUSIONS. These factors were also considered by the independent Directors meeting separately from the full Board, assisted by experienced counsel, both to the Fund and to the independent Directors. Fund counsel and the independent Directors' counsel are both independent of the Manager within the meaning and intent of the Securities and Exchange Commission Rules. Based on its review of the information it received and its evaluations and considerations described above, the Board, including a majority of the independent Directors, concluded that the nature, extent and quality of the services provided to the Fund by the Manager are a benefit to the Fund and in the best interest of the Fund's shareholders and that the amount and structure of the compensation received by the Manager and its affiliates from the Fund are reasonable in relation to the services provided. Accordingly, the Board elected to continue the advisory agreement for another year.

SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS. THE FUND'S GOVERNANCE COMMITTEE PROVISIONS WITH RESPECT TO NOMINATIONS OF DIRECTORS/TRUSTEES TO THE RESPECTIVE BOARDS 1. The Fund's Governance Committee (the "Committee") will evaluate potential Board candidates to assess their qualifications. The Committee shall have the authority, upon approval of the Board, to retain an executive search firm to assist in this effort. The Committee may consider recommendations by business and personal contacts of current Board members and by executive search firms which the Committee may engage from time to time and may also consider shareholder recommendations. The Committee may consider the advice and recommendation of the Funds' investment manager and its affiliates in making the selection. 2. The Committee shall screen candidates for Board membership. The Committee has not established specific qualifications that it believes must be met by a trustee nominee. 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. ITEM 11. CONTROLS AND PROCEDURES. Based on their evaluation of the registrant's disclosure controls and procedures (as defined in rule 30a-3(c) under the Investment Company Act of 1940 (17 CFR 270.30a-3(c)) as of August 31, 2005, the registrant's principal executive officer and principal financial officer found the registrant's disclosure controls and procedures to provide reasonable assurances that information required to be disclosed by the registrant in the reports that it files under the Securities Exchange Act of 1934 (a) is accumulated and communicated to registrant's management, including its principal executive officer and principal financial officer, to allow timely decisions regarding required disclosure, and (b) is recorded, processed, summarized and reported, within the time periods specified in the rules and forms adopted by the U.S. Securities and Exchange Commission. There have been no changes in the registrant's internal controls over financial reporting that occurred during the registrant's second fiscal quarter of the period covered by this report that have materially affected, or are reasonably likely to materially affect, the registrant's internal control over financial reporting.
