BELOW IS A DISCUSSION BY OPPENHEIMERFUNDS, INC., OF THE FUND'S PERFORMANCE DURING ITS FISCAL YEAR ENDED OCTOBER 31, 2007, 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 ending October 31, 2007, Oppenheimer MidCap Fund produced positive absolute results but underperformed its benchmark, the S&P MidCap 400 Index. We attribute a majority of the underperformance to an unfavorable overweight position combined with weak stock selection in the financials sector. Unsuccessful stock selection in the industrials and materials sectors also hurt Fund results. In contrast, the Fund benefited from very strong stock selection in the consumer discretionary sector, despite maintaining an underweight position in the sector over the period. Additionally, the Fund advanced on the positive performance generated by individual stocks in such sectors as health care, energy and information technology. Over the period a management change occurred. John O'Hare managed the Fund through June 4, 2007. Effective June 5, 2007, Richard Royce was named portfolio manager and is principally responsible for the day-to-day management of the Fund's investments. Richard Royce joined OppenheimerFunds in May 2007. Prior to joining OppenheimerFunds, Mr. Royce worked at JPMorgan Asset Management as a vice president and co-portfolio manager of the America Equity Fund. During his almost 9-year tenure at JPMorgan, Mr. Royce also worked as a technology and media analyst. Prior to JPMorgan Asset Management, Mr. Royce worked as an analyst at Mark Asset Management, focusing on technology and real estate. In light of the management change, we would like to highlight our investment process for shareholders. We follow a bottom-up, research-driven stock selection process, meaning we emphasize company and industry analysis and de-emphasize macroeconomic analysis. The team's investment process focuses on identifying companies with sustainable competitive positioning and large addressable markets, management teams committed to increasing intrinsic value per share, and whose valuation does not reflect these factors. On a relative basis, the Fund's weakest performing sectors were the financials, industrials and materials. Within the financials sector, disappointing stock selection combined with an overweight position served as the major source of the Fund's relative underperformance. In general, the operating environment for many financial stocks was difficult given the flat to inverted slope of the yield curve and turmoil in the debt markets. As a result of this tough environment, many of the Fund's financial holdings were hurt. Top detractors included Ambac Financial Group, Inc., commercial real estate management and development companies Jones Lang LaSalle, Inc. and CB Richard Ellis Group, Inc. and three 10 | OPPENHEIMER MIDCAP FUND regional banks. We have reduced our positions in all three regional banks because we believed that their valuations were too high relative to the risks and growth rates seen in the market. In terms of the industrials and materials sectors, the Fund's underperformance can be attributed to not owning the export-oriented, cyclical companies which outperformed during the period. As a general rule, the Fund tends to be underweight in cyclical and commodity-oriented sectors because these areas of the market tend to lack the fundamental growth qualities we look for when investing. Given this, the Fund did not participate in the strong gains posted by many companies in the industrials and materials sectors. The Fund's best relative gains were achieved by holdings within the consumer discretionary sector. The top performing security within the sector, and for the Fund in general, was Las Vegas Sands Corp., a hotel, gaming and resort development company. Concern over the company's new property in China prevented the market from fully recognizing the value in the company's other properties, which resulted in our view of an undervaluation in its stock price. However, as the company's strong fundamentals became apparent to investors, its stock price rapidly increased. Other contributors included Tiffany & Co. and GameStop Corp. The outperformance by specialty retailer Tiffany & Co. was driven by the successful outcome of its reorganization which resulted in better growth in its retail operations, accelerated store openings and improved operating margins. GameStop, one of the largest retailers of new and used video games and hardware and entertainment software, benefited from its competitive positioning within its marketplace which drove its stock price up. The Fund also benefited from the strong absolute performance generated by individual holdings within the industrials, health care, energy and information technology sectors. In the industrials sector, Stericycle, Inc., the large domestic medical waste treatment and disposal company, posted strong absolute returns. Stericycle's favorable results can be attributed to its strong management team, which led the company to post profitable financial results. Within the health care sector, Covance, Inc., a contract resource organization that develops and carries out preclinical and clinical trials of potential commercial drugs for pharmaceutical companies, benefited from a trend within the industry to outsource such work. Despite an underweight position in the energy sector, the Fund significantly outpaced its benchmark. We attribute the outperformance to strong stock selection. Leading the group was Smith International, Inc., a supplier of products and services to the oil and gas exploration and production industry. As global demand for oil grows, energy companies have increased capital spending on equipment supplies and services in order to uncover more reserves benefiting companies like Smith International. In the information technology 11 | OPPENHEIMER MIDCAP FUND FUND PERFORMANCE DISCUSSION - -------------------------------------------------------------------------------- sector, the top performer was Trimble Navigation Ltd. The company, which makes navigation systems and software based on the global positioning system (GPS) satellite network, advanced on growing demand for its products. MID-CAP STOCKS TEND TO BE MORE SENSITIVE TO CHANGES IN EARNINGS EXPECTATIONS, AND TEND TO HAVE LOWER TRADING VOLUMES THAN LARGE-CAP SECURITIES, AND THEREFORE THEY MAY EXPERIENCE MORE ABRUPT AND ERRATIC PRICE MOVEMENTS. 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 October 31, 2007. In the case of Class A, Class B, Class C and Class Y shares, performance is measured from the inception of each Class on December 1, 1997. In the case of Class N shares, performance is measured from inception of the Class on March 1, 2001. The Fund's performance reflects the deduction of the maximum initial sales charge on Class A shares, the applicable contingent deferred sales charge on Class B, Class C and Class N shares, and reinvestments of all dividends and capital gains distributions. Past performance cannot guarantee future results. The Fund's performance is compared to that of the S&P MidCap 400 Index and the Russell Midcap(R) Growth Index. The S&P MidCap 400 Index is an unmanaged index of 400 domestic stocks chosen for market size liquidity, and industry group representation. The Russell Midcap Growth Index is an unmanaged index that measures the performance of those Russell Midcap companies with higher price-to-book ratios and higher forecasted growth values. The stocks are also members of the Russell 1000 Growth Index, as ranked by total market capitalization. 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. 12 | OPPENHEIMER MIDCAP FUND CLASS A SHARES COMPARISON OF CHANGE IN VALUE OF $10,000 HYPOTHETICAL INVESTMENTS IN: Oppenheimer MidCap Fund (Class A) S&P MidCap 400 Index Russell Midcap Growth Index [THE FOLLOWING TABLE WAS REPRESENTED BY A LINE GRAPH IN THE PRINTED MATERIAL.] Oppenheimer Russell Midcap MidCap Fund (Class A) S&P MidCap 400 Index Growth Index 12/01/1997 $ 9,425 $ 10,000 $ 10,000 01/31/1998 $ 9,519 $ 10,190 $ 9,949 04/30/1998 $ 12,271 $ 11,743 $ 11,494 07/31/1998 $ 11,744 $ 10,848 $ 10,848 10/31/1998 $ 10,207 $ 10,515 $ 10,137 01/31/1999 $ 13,390 $ 11,892 $ 12,299 04/30/1999 $ 14,636 $ 12,498 $ 12,912 07/31/1999 $ 16,382 $ 12,943 $ 13,201 10/31/1999 $ 18,760 $ 12,731 $ 13,954 01/31/2000 $ 25,875 $ 13,795 $ 18,062 04/30/2000 $ 27,564 $ 15,438 $ 19,758 07/31/2000 $ 29,716 $ 15,713 $ 18,978 10/31/2000 $ 28,697 $ 16,760 $ 19,351 01/31/2001 $ 23,903 $ 17,052 $ 16,854 04/30/2001 $ 16,901 $ 16,525 $ 13,935 07/31/2001 $ 15,618 $ 16,591 $ 12,941 10/31/2001 $ 13,608 $ 14,674 $ 11,072 01/31/2002 $ 13,910 $ 16,493 $ 12,317 04/30/2002 $ 13,419 $ 17,611 $ 11,844 07/31/2002 $ 11,201 $ 14,491 $ 9,229 10/31/2002 $ 10,786 $ 13,972 $ 9,122 01/31/2003 $ 10,182 $ 13,759 $ 9,151 04/30/2003 $ 10,871 $ 14,528 $ 9,870 07/31/2003 $ 12,617 $ 16,498 $ 11,366 10/31/2003 $ 13,183 $ 18,266 $ 12,707 01/31/2004 $ 13,230 $ 19,638 $ 13,625 04/30/2004 $ 13,608 $ 19,532 $ 13,436 07/31/2004 $ 13,400 $ 19,440 $ 13,047 10/31/2004 $ 14,193 $ 20,283 $ 13,821 01/31/2005 $ 15,155 $ 21,819 $ 14,823 04/30/2005 $ 14,664 $ 21,434 $ 14,384 07/31/2005 $ 16,637 $ 24,473 $ 16,394 10/31/2005 $ 16,571 $ 23,863 $ 16,019 01/31/2006 $ 18,033 $ 26,686 $ 18,096 04/30/2006 $ 18,411 $ 27,505 $ 18,451 07/31/2006 $ 16,608 $ 25,521 $ 16,883 10/31/2006 $ 17,618 $ 27,067 $ 18,344 01/31/2007 $ 18,203 $ 28,812 $ 19,580 04/30/2007 $ 18,496 $ 30,309 $ 20,503 07/31/2007 $ 18,533 $ 29,792 $ 20,496 10/31/2007 $ 20,053 $ 31,674 $ 21,961 AVERAGE ANNUAL TOTAL RETURNS OF CLASS A SHARES WITH SALES CHARGE OF THE FUND AT 10/31/07 1-Year 7.27% 5-Year 11.87% Since Inception (12/1/97) 7.27% THE PERFORMANCE DATA QUOTED REPRESENTS PAST PERFORMANCE, WHICH DOES NOT GUARANTEE FUTURE RESULTS.

The Fund's total returns shown do not reflect the deduction of income taxes on an individual's investment. Taxes may reduce your actual investment returns on income or gains paid by the Fund or any gains you may realize if you sell your shares. INVESTORS SHOULD CONSIDER THE FUND'S INVESTMENT OBJECTIVES, RISKS, AND OTHER CHARGES AND EXPENSES CAREFULLY BEFORE INVESTING. THE FUND'S PROSPECTUS CONTAINS THIS AND OTHER INFORMATION ABOUT THE FUND, AND MAY BE OBTAINED BY ASKING YOUR FINANCIAL ADVISOR, CALLING US AT 1.800.525.7048 OR VISITING OUR WEBSITE AT WWW.OPPENHEIMERFUNDS.COM. READ THE PROSPECTUS CAREFULLY BEFORE INVESTING. The Fund's investment strategy and focus can change over time. The mention of specific fund holdings does not constitute a recommendation by OppenheimerFunds, Inc. CLASS A shares of the Fund were first publicly offered on 12/1/97. Unless otherwise noted, Class A returns include the current maximum initial sales charge of 5.75%. CLASS B shares of the Fund were first publicly offered on 12/1/97. Unless otherwise noted, Class B returns include the applicable contingent deferred sales charge of 5% (1-year) and 2% (5-year). Class B shares are subject to an annual 0.75% asset-based sales charge. Because Class B shares convert to Class A shares 72 months after purchase, the "since inception" return for Class B uses Class A performance for the period after conversion. CLASS C shares of the Fund were first publicly offered on 12/1/97. Unless otherwise noted, 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. 18 | OPPENHEIMER MIDCAP FUND NOTES - -------------------------------------------------------------------------------- CLASS Y shares of the Fund were first publicly offered on 12/1/97. Class Y shares are offered only to certain institutional investors under special agreement with the Distributor. An explanation of the calculation of performance is in the Fund's Statement of Additional Information. 19 | OPPENHEIMER MIDCAP 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 October 31, 2007. 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 the Statement of Additional Information). Therefore, the "hypothetical" 20 | OPPENHEIMER MIDCAP FUND 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 5/1/07 10/31/07 OCTOBER 31, 2007 - ------------------------------------------------------------------------------ Class A Actual $ 1,000.00 $ 1,084.20 $ 6.85 - ------------------------------------------------------------------------------ Class A Hypothetical 1,000.00 1,018.65 6.64 - ------------------------------------------------------------------------------ Class B Actual 1,000.00 1,080.40 10.54 - ------------------------------------------------------------------------------ Class B Hypothetical 1,000.00 1,015.12 10.21 - ------------------------------------------------------------------------------ Class C Actual 1,000.00 1,079.90 10.80 - ------------------------------------------------------------------------------ Class C Hypothetical 1,000.00 1,014.87 10.46 - ------------------------------------------------------------------------------ Class N Actual 1,000.00 1,083.40 8.01 - ------------------------------------------------------------------------------ Class N Hypothetical 1,000.00 1,017.54 7.76 - ------------------------------------------------------------------------------ Class Y Actual 1,000.00 1,086.60 4.74 - ------------------------------------------------------------------------------ Class Y Hypothetical 1,000.00 1,020.67 4.59 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). Those annualized expense ratios, excluding indirect expenses from affiliated fund, based on the 6-month period ended October 31, 2007 are as follows: CLASS EXPENSE RATIOS - ----------------------------- Class A 1.30% - ----------------------------- Class B 2.00 - ----------------------------- Class C 2.05 - ----------------------------- Class N 1.52 - ----------------------------- Class Y 0.90 The expense ratios reflect reduction to custodian expenses and voluntary waivers or reimbursements by the Fund's Manager and Transfer Agent that can be terminated at any time, without advance notice. The "Financial Highlights" tables in the Fund's financial statements, included in this report, also show the gross expense ratios, without such waivers or reimbursements and reduction to custodian expenses, if applicable. - -------------------------------------------------------------------------------- 21 | OPPENHEIMER MIDCAP FUND STATEMENT OF INVESTMENTS October 31, 2007 - -------------------------------------------------------------------------------- SHARES VALUE - -------------------------------------------------------------------------------- COMMON STOCKS--99.0% - -------------------------------------------------------------------------------- CONSUMER DISCRETIONARY--19.8% - -------------------------------------------------------------------------------- DIVERSIFIED CONSUMER SERVICES--1.1% ITT Educational Services, Inc. 1 84,200 $ 10,709,398 - -------------------------------------------------------------------------------- HOTELS, RESTAURANTS & LEISURE--2.2% Las Vegas Sands Corp. 1 168,800 22,463,904 - -------------------------------------------------------------------------------- HOUSEHOLD DURABLES--0.7% Harman International Industries, Inc. 87,100 7,333,820 - -------------------------------------------------------------------------------- INTERNET & CATALOG RETAIL--2.0% Liberty Media Holding Corp.-Interactive, Series A 1 967,600 20,542,148 - -------------------------------------------------------------------------------- MEDIA--4.9% Cablevision Systems Corp.

SEE ACCOMPANYING NOTES TO FINANCIAL STATEMENTS. 33 | OPPENHEIMER MIDCAP FUND NOTES TO FINANCIAL STATEMENTS - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 1. SIGNIFICANT ACCOUNTING POLICIES Oppenheimer MidCap 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 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(R) 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 trading session ending at, or most recently prior to, the time when the Fund's assets are 34 | OPPENHEIMER MIDCAP FUND valued. Options are valued daily based upon the last sale price on the principal exchange on which the option is traded. 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. Investments in open-end registered investment companies (including affiliated funds) are valued at that fund's net asset value. Short-term "money market type" debt securities with remaining maturities of sixty days or less are valued at amortized cost (which approximates market value). - -------------------------------------------------------------------------------- INVESTMENT IN OPPENHEIMER INSTITUTIONAL MONEY MARKET FUND. The Fund is permitted to invest daily available cash balances in an affiliated money market fund. The Fund may invest the available cash in Class E shares of Oppenheimer Institutional Money Market Fund ("IMMF") which seeks current income and stability of principal. IMMF is a registered open-end management investment company, regulated as a money market fund under the Investment Company Act of 1940, as amended. The Manager is also the investment advisor of IMMF. The Fund's investment in IMMF is included in the Statement of Investments, if applicable. As a shareholder, the Fund is subject to its proportional share of IMMF's Class E expenses, including its management fee. The Manager will waive fees and/or reimburse Fund expenses in an amount equal to the indirect management fees incurred through the Fund's investment in IMMF. - -------------------------------------------------------------------------------- ALLOCATION OF INCOME, EXPENSES, GAINS AND LOSSES. Income, expenses (other than those attributable to a specific class), gains and losses are allocated on a daily basis to each class of shares based upon the relative proportion of net assets represented by such class. Operating expenses directly attributable to a specific class are charged against the operations of that class. - -------------------------------------------------------------------------------- FEDERAL TAXES. The Fund intends to comply with provisions of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its investment company taxable income, including any net realized gain on investments not offset by capital loss carryforwards, if any, to shareholders, therefore, no federal income or excise tax provision is required. The tax components of capital shown in the table below represent distribution requirements the Fund must satisfy under the income tax regulations, losses the Fund may be 35 | OPPENHEIMER MIDCAP FUND NOTES TO FINANCIAL STATEMENTS Continued - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 1. SIGNIFICANT ACCOUNTING POLICIES Continued 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.

As of October 31, 2007, the Fund had $725,704,087 of net capital loss carryforwards available to offset future realized capital gains, if any, and thereby reduce future taxable gain distributions. As of October 31, 2007, details of the capital loss carryforwards were as follows: EXPIRING ---------------------------- 2009 $ 420,157,455 2010 237,910,335 2011 67,636,297 ------------- Total $ 725,704,087 ============= 2. During the fiscal year ended October 31, 2007, the Fund utilized $241,392,441 of capital loss carryforward to offset capital gains realized in that fiscal year. 3. During the fiscal year ended October 31, 2006, the Fund utilized $98,062,815 of capital loss carryforward to offset capital gains realized in that fiscal year. 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 October 31, 2007. Net assets of the Fund were unaffected by the reclassifications. REDUCTION TO INCREASE TO ACCUMULATED ACCUMULATED NET REDUCTION TO NET INVESTMENT REALIZED LOSS PAID-IN CAPITAL LOSS ON INVESTMENTS -------------------------------------------------- $10,047,271 $10,307,931 $260,660 No distributions were paid during the years ended October 31, 2007 and October 31, 2006. 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 October 31, 2007 are noted below. The primary difference between book and tax appreciation or depreciation of securities and other investments, if applicable, 36 | OPPENHEIMER MIDCAP FUND is attributable to the tax deferral of losses or tax realization of financial statement unrealized gain or loss. Federal tax cost of securities $ 862,404,193 ============= Gross unrealized appreciation $ 171,762,530 Gross unrealized depreciation (29,167,924) ------------- Net unrealized appreciation $ 142,594,606 ============= - -------------------------------------------------------------------------------- TRUSTEES' COMPENSATION. The Fund has adopted an unfunded retirement plan for the Fund's independent trustees. Benefits are based on years of service and fees paid to each trustee during the years of service. During the year ended October 31, 2007, the Fund's projected benefit obligations were increased by $16,886 and payments of $6,859 were made to retired trustees, resulting in an accumulated liability of $154,778 as of October 31, 2007. The Board of Trustees has adopted a compensation deferral 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 compensation deferral 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 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. 37 | OPPENHEIMER MIDCAP FUND NOTES TO FINANCIAL STATEMENTS Continued - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 1. SIGNIFICANT ACCOUNTING POLICIES Continued 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 no par value shares of beneficial interest of each class.

OppenheimerFunds Services (OFS), a division of the Manager, acts as the transfer and shareholder servicing agent for the Fund. The Fund pays OFS a per account fee. For the year ended October 31, 2007, the Fund paid $3,688,659 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.

Fees incurred by the Fund under the plan are detailed in the Statement of Operations. 39 | OPPENHEIMER MIDCAP FUND NOTES TO FINANCIAL STATEMENTS Continued - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 4. FEES AND OTHER TRANSACTIONS WITH AFFILIATES Continued 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 determines its uncompensated expenses under the plan at calendar quarter ends. The Distributor's aggregate uncompensated expenses under the plan at September 30, 2007 for Class B, Class C and Class N shares were $16,964,500, $5,260,405 and $753,805, respectively. Fees incurred by the Fund under the plans are detailed in the Statement of Operations. - -------------------------------------------------------------------------------- SALES CHARGES.

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 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 October 31, 2007, the Manager has evaluated the implications of FIN 48 and does not currently anticipate a material impact to the Fund's financial statements. The Manager will continue to monitor the Fund's tax positions prospectively for potential future impacts. In September 2006, ("FASB") issued Statement of Financial Accounting Standards ("SFAS") No. 157, FAIR VALUE MEASUREMENTS. This standard establishes a single authoritative definition of fair value, sets out a framework for measuring fair value and expands disclosures about fair value measurements. SFAS No. 157 applies to fair value measurements already required or permitted by existing standards. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. As of October 31, 2007, the Manager does not believe the adoption of SFAS No. 157 will materially impact the financial statement amounts; however, additional disclosures may be required about the inputs used to develop the measurements and the effect of certain of the measurements on changes in net assets for the period. - -------------------------------------------------------------------------------- 6. SUBSEQUENT EVENT On November 19, 2007, the Fund's Board of Trustees voted to freeze participation in the retirement plan for the Board's independent trustees by not adding new participants to the plan after December 31, 2007. Active independent trustees who have accrued benefits under the plan prior to the freeze date will elect a distribution method with respect to their benefits. Benefits already accrued under the plan for Trustees who were participants prior to that freeze date are not affected. 41 | OPPENHEIMER MIDCAP FUND REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- THE BOARD OF TRUSTEES AND SHAREHOLDERS OF OPPENHEIMER MIDCAP FUND: We have audited the accompanying statement of assets and liabilities of Oppenheimer MidCap Fund, including the statement of investments, as of October 31, 2007, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the years in the two-year period then ended, and the financial highlights for each of the years in the five-year period then ended. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of October 31, 2007, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Oppenheimer MidCap Fund as of October 31, 2007, the results of its operations for the year then ended, the changes in its net assets for each of the years in the two-year period then ended, and the financial highlights for each of the years in the five-year period then ended, in conformity with U.S. generally accepted accounting principles.

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 Agreement. The Board employs an independent consultant to prepare a report that provides information, including comparative information, that the Board requests for that purpose. In addition, the Board receives information throughout the year regarding Fund services, fees, expenses and performance. The Manager and the independent consultant provided information to the Board on the following factors: (i) the nature, quality and extent of the Manager's services, (ii) the investment performance of the Fund and the Manager, (iii) the fees and expenses of the Fund, including comparative expense information, (iv) the profitability of the Manager and its affiliates, including an analysis of the cost of providing services by the Manager and its affiliates, (v) the extent to which economies of scale are realized as the Fund grows and whether fee levels reflect these economies of scale for Fund investors and (vi) other benefits to the Manager from its relationship with the Fund. The Board was aware that there are alternatives to retaining the Manager. NATURE AND EXTENT OF SERVICES. The Board considered information about the nature and extent of the services provided to the Fund and information regarding the Manager's key personnel who provide such services. The Manager's duties include providing the Fund with the services of the portfolio manager and the Manager's investment team, who provide research, analysis and other advisory services in regard to the Fund's investments; securities trading services; oversight of third party service providers; monitoring compliance with applicable Fund policies and procedures and adherence to the Fund's investment restrictions. The Manager is responsible for providing certain administrative services to the Fund as well. Those services include providing and supervising all administrative and clerical personnel who are necessary in order to provide effective corporate administration for the Fund; compiling and maintaining records with respect to the Fund's operations; preparing and filing reports required by the Securities and Exchange Commission; preparing periodic reports regarding the operations of the Fund for its shareholders; preparing proxy materials for shareholder meetings; and preparing the registration statements required by Federal and state securities laws for the sale of the Fund's shares. The Manager also provides the Fund with office space, facilities and equipment. QUALITY OF SERVICES. The Board also considered the quality of the services provided and the quality of the Manager's resources that are available to the Fund. The Board took account of the fact that the Manager has had over forty years of experience as an invest- 45 | OPPENHEIMER MIDCAP FUND BOARD APPROVAL OF THE FUND'S INVESTMENT ADVISORY AGREEMENT Unaudited - -------------------------------------------------------------------------------- ment 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 has received regarding the experience and professional qualifications of the Manager's personnel and the size and functions of its staff. In its evaluation of the quality of the portfolio management services provided, the Board considered the experience of Richard Royce, the portfolio manager for the Fund, and the Manager's Growth investment team and analysts. The Board members also considered their experiences with the Manager and its officers and other personnel through their service on the Boards of the Fund and other funds advised by the Manager. The Board considered information regarding the quality of services provided by affiliates of the Manager, which its members have become knowledgeable about in connection with the renewal of the Fund's service agreements. In light of the foregoing, the Board concluded that the Fund benefits from the services provided under the Agreement and from the Manager's experience, reputation, personnel, operations, and resources. INVESTMENT PERFORMANCE OF THE MANAGER AND THE FUND. During the year, the Manager provided information on the investment performance of the Fund and the Manager at each Board meeting, including comparative performance information. 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 retail front-end load and no-load mid-cap growth funds advised by the Manager and by other investment advisers. The Board noted that the Fund's one-year, three-year, and five-year performance were below its peer group median. The Board also noted the recent changes of the Fund's portfolio manager and to the Manager's Growth investment team and analysts. MANAGEMENT FEES AND EXPENSES. The Board reviewed the fees paid to the Manager and its affiliates and the other expenses borne by the Fund. The Board also considered the comparability of the fees charged and the services provided to the Fund to the fees and services for other clients or accounts advised by the Manager. The independent consultant provided comparative data in regard to the fees and expenses of the Fund, other mid-cap growth funds and other funds with comparable asset levels and distribution features. The Board noted that the Fund's contractual and actual management fees are lower than its peer group median although its total expenses are higher than its peer group median. ECONOMIES OF SCALE. The Board reviewed the extent to which the Manager may realize economies of scale in managing and supporting the Fund, the extent to which those economies of scale benefit the Fund's shareholders and the current level of Fund assets in relation to the Fund's breakpoint schedule for its management fees. The Board also noted 46 | OPPENHEIMER MIDCAP FUND the Fund's breakpoints, which are intended to share economies of scale that may exist as the Fund grows with its shareholders. BENEFITS TO THE MANAGER. The Board considered information regarding the Manager's costs in serving as the Fund's investment adviser, including the costs associated with the personnel and systems necessary to manage the Fund, and information regarding the Manager's profitability from its relationship with the Fund. 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 to considering the profits realized by the Manager, the Board considered information 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 for services provided and research provided to the Manager in connection with permissible brokerage arrangements (soft dollar arrangements). CONCLUSIONS. These factors were also considered by the independent Trustees meeting separately from the full Board, assisted by experienced counsel to the Fund and the independent Trustees. Fund counsel is 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 described above, the Board, including a majority of the independent Trustees, 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 are reasonable in relation to the services provided. Accordingly, the Board elected to continue the Agreement for another year. In arriving at this decision, the Board did not single out any factor or factors as being more important than others, but considered all of the factors together. The Board judged the terms and conditions of the Agreement, including the management fee, in light of all of the surrounding circumstances. 47 | OPPENHEIMER MIDCAP FUND TRUSTEES AND OFFICERS Unaudited - -------------------------------------------------------------------------------- - ---------------------------------------------------------------------------------------------------------------------------------- NAME, POSITION(S) HELD WITH THE PRINCIPAL OCCUPATION(S) DURING THE PAST 5 YEARS; OTHER TRUSTEESHIPS/DIRECTORSHIPS HELD; NUMBER FUND, LENGTH OF SERVICE, AGE OF PORTFOLIOS IN THE FUND COMPLEX CURRENTLY OVERSEEN INDEPENDENT THE ADDRESS OF EACH TRUSTEE IN THE CHART BELOW IS 6803 S.

SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS. THE FUND'S AUDIT COMMITTEE PROVISIONS WITH RESPECT TO NOMINATIONS OF DIRECTORS/TRUSTEES TO THE RESPECTIVE BOARDS 1. The Fund's Audit 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 10/31/2007, 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.
