BELOW IS A DISCUSSION BY OPPENHEIMERFUNDS, INC., OF THE FUND'S PERFORMANCE DURING ITS FISCAL YEAR ENDED OCTOBER 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. The Fund produced relatively strong performance relative to its benchmark, the S&P Mid-Cap 400 Index during its fiscal year. The Fund's competitive performance can be attributed to strong stock selection, particularly in the specialty retail, healthcare and financial sectors. On the negative side, the Fund's relative underweight in energy hurt performance, as energy was the best performing sector in the Index over the period. Outside of energy, the Fund's overweight in IT services combined with several holdings within the electronic equipment and software sectors hampered performance. The Fund's investment strategy focuses on high-growth companies that are industry leaders within their marketplace. We target those we believe possess competitive advantages, stable earnings, sustainable growth rates and experienced management teams with proven records. Our investment strategy succeeded in identifying high performing companies across many market sectors. During the period, specialty retail proved to be the Fund's best performing area, benefiting from a strong economy and a voracious consumer appetite. Top contributors to performance were Chico's FAS, Inc., Urban Outfitters, Inc. and Coach, Inc. Women's clothing retailer, Chico's FAS, Inc., benefited from very strong same-store sales growth and a highly attentive customer service philosophy. Urban Outfitters, Inc., a fashion retailer for young women and men, benefited from strong management, low cost overseas manufacturing and trendy fashion designs. Coach, Inc., a designer, manufacturer and marketer of fine leather goods and accessories, continued to profit from its handbag collection as well as its successful expansion into Japan. As of the end of the period, we have trimmed our exposure to this sector given our concern over the impact that rising energy prices will have on the consumer. Stocks within the healthcare sector also performed well for the Fund. During times of economic uncertainty, as was the case for part of the reporting period, investors tend to flock to defensive investments such as healthcare stocks. The Fund's strongest healthcare holding was Coventry Health Care, Inc., a firm that provides managed healthcare services. Coventry Health Care, Inc. successfully completed its acquisition of First Health Group Corp., which boosted profitability and produced greater margins. The financials sector also helped performance. The Fund benefited from its underweight in commercial banks, as the group was down overall. Among the best performing stocks in this sector were the Chicago Mercantile Exchange Holdings, Inc. and Legg 9 | OPPENHEIMER MIDCAP FUND FUND PERFORMANCE DISCUSSION - -------------------------------------------------------------------------------- Mason, Inc. The Chicago Mercantile Exchange Holdings, Inc., the largest U.S. futures exchange and diversified and innovative global financial services marketplace, profited from its new products and trading platform. Legg Mason, Inc., a financial services firm, sold its brokerage unit to Citi Corp. This strategic realignment has allowed the firm to focus on its more lucrative asset management business and as a result the company's stock has soared. Lastly, within the consumer staples sector, Whole Foods Market, Inc. outperformed. A strong management team that successfully executed on its corporate plan drove the company's stock price higher during the period. Despite strong performance from most of the Fund's holdings, there were some detractors. One of the primary detractors from Fund performance was being underweighted in energy versus the Index. Approximately half way through the reporting period the S&P Mid-Cap 400 Index increased its exposure to the energy sector. A reallocation of this kind is very uncommon and as a result the Fund, which had been overweighted in energy versus the Index, became underweighted. In addition to energy, holdings within the information technology sector held performance back. Disappointments included information technology services providers, such as Affiliated Computer Services, Inc. and Alliance Data Systems Corp. Also hampering performance were the Fund's holdings in the electronic equipment and instruments sector, specifically CDW Corp. and National Instruments Corp. Lastly, in the consumer discretionary sector, Brunswick Corp., a global leader in the leisure products industry, suffered from weak sales due to consumer concerns over rising energy prices. 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, 2005. 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. 10 | OPPENHEIMER MIDCAP FUND The Fund's performance is compared to that of the S&P Mid-Cap 400 Index. The S&P Mid-Cap 400 Index is an unmanaged index of 400 domestic stocks chosen for market size, market size/liquidity or market size and liquidity, and industry group representation. 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 MIDCAP FUND FUND PERFORMANCE DISCUSSION - -------------------------------------------------------------------------------- CLASS A SHARES COMPARISON OF CHANGE IN VALUE OF $10,000 HYPOTHETICAL INVESTMENTS IN: Oppenheimer MidCap Fund (Class A) S&P Mid-Cap 400 Index [THE FOLLOWING TABLE WAS REPRESENTED BY A LINE GRAPH IN THE PRINTED MATERIAL.] Oppenheimer S&P Midcap MidCap Fund (Class A) 400 Index 12/01/1997 9,425 10,000 01/31/1998 9,519 10,190 04/30/1998 12,271 11,743 07/31/1998 11,744 10,848 10/31/1998 10,207 10,515 01/31/1999 13,390 11,892 04/30/1999 14,636 12,498 07/31/1999 16,382 12,943 10/31/1999 18,760 12,731 01/31/2000 25,875 13,795 04/30/2000 27,564 15,438 07/31/2000 29,716 15,713 10/31/2000 28,697 16,760 01/31/2001 23,903 17,052 04/30/2001 16,901 16,525 07/31/2001 15,618 16,591 10/31/2001 13,608 14,674 01/31/2002 13,910 16,493 04/30/2002 13,419 17,611 07/31/2002 11,201 14,491 10/31/2002 10,786 13,972 01/31/2003 10,182 13,759 04/30/2003 10,871 14,528 07/31/2003 12,617 16,498 10/31/2003 13,183 18,266 01/31/2004 13,230 19,638 04/30/2004 13,608 19,532 07/31/2004 13,400 19,440 10/31/2004 14,193 20,283 01/31/2005 15,155 21,819 04/30/2005 14,664 21,434 07/31/2005 16,637 24,473 10/31/2005 16,571 23,863 AVERAGE ANNUAL TOTAL RETURN OF CLASS A SHARES WITH SALES CHARGE OF THE FUND AT 10/31/05 1 Year 10.04% 5 Year -11.46% Since Inception (12/1/97) 6.59% 12 | OPPENHEIMER MIDCAP FUND CLASS B SHARES COMPARISON OF CHANGE IN VALUE OF $10,000 HYPOTHETICAL INVESTMENTS IN: Oppenheimer MidCap Fund (Class B) S&P Mid-Cap 400 Index [THE FOLLOWING TABLE WAS REPRESENTED BY A LINE GRAPH IN THE PRINTED MATERIAL.] Oppenheimer S&P Midcap MidCap Fund (Class B) 400 Index 12/01/1997 10,000 10,000 01/31/1998 10,080 10,190 04/30/1998 12,980 11,743 07/31/1998 12,390 10,848 10/31/1998 10,770 10,515 01/31/1999 14,097 11,892 04/30/1999 15,379 12,498 07/31/1999 17,181 12,943 10/31/1999 19,644 12,731 01/31/2000 27,043 13,795 04/30/2000 28,766 15,438 07/31/2000 30,948 15,713 10/31/2000 29,827 16,760 01/31/2001 24,801 17,052 04/30/2001 17,502 16,525 07/31/2001 16,150 16,591 10/31/2001 14,037 14,674 01/31/2002 14,318 16,493 04/30/2002 13,787 17,611 07/31/2002 11,494 14,491 10/31/2002 11,034 13,972 01/31/2003 10,393 13,759 04/30/2003 11,084 14,528 07/31/2003 12,846 16,498 10/31/2003 13,387 18,266 01/31/2004 13,431 19,638 04/30/2004 13,815 19,532 07/31/2004 13,604 19,440 10/31/2004 14,409 20,283 01/31/2005 15,386 21,819 04/30/2005 14,888 21,434 07/31/2005 16,890 24,473 10/31/2005 16,823 23,863 AVERAGE ANNUAL TOTAL RETURN OF CLASS B SHARES WITH SALES CHARGE OF THE FUND AT 10/31/05 1 Year 10.89% 5 Year -11.44% Since Inception (12/1/97) 6.79% THE PERFORMANCE DATA QUOTED REPRESENTS PAST PERFORMANCE, WHICH DOES NOT GUARANTEE FUTURE RESULTS.

Class N shares are subject to an annual 0.25% asset-based sales charge. 17 | 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. 18 | 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, 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 MIDCAP 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 (5/1/05) (10/31/05) OCTOBER 31, 2005 - ------------------------------------------------------------------------------ Class A Actual $1,000.00 $ 1,130.00 $ 7.27 - ------------------------------------------------------------------------------ Class A Hypothetical 1,000.00 1,018.40 6.89 - ------------------------------------------------------------------------------ Class B Actual 1,000.00 1,125.80 11.42 - ------------------------------------------------------------------------------ Class B Hypothetical 1,000.00 1,014.52 10.82 - ------------------------------------------------------------------------------ Class C Actual 1,000.00 1,125.80 11.20 - ------------------------------------------------------------------------------ Class C Hypothetical 1,000.00 1,014.72 10.62 - ------------------------------------------------------------------------------ Class N Actual 1,000.00 1,128.80 8.35 - ------------------------------------------------------------------------------ Class N Hypothetical 1,000.00 1,017.39 7.91 - ------------------------------------------------------------------------------ Class Y Actual 1,000.00 1,132.60 4.74 - ------------------------------------------------------------------------------ Class Y Hypothetical 1,000.00 1,020.77 4.49 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 based on the 6-month period ended October 31, 2005 are as follows: CLASS EXPENSE RATIOS - ----------------------------- Class A 1.35% - ----------------------------- Class B 2.12 - ----------------------------- Class C 2.08 - ----------------------------- Class N 1.55 - ----------------------------- Class Y 0.88 The expense ratios reflect voluntary waivers or reimbursements of expenses by the Fund's 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. - -------------------------------------------------------------------------------- 20 | OPPENHEIMER MIDCAP FUND STATEMENT OF INVESTMENTS October 31, 2005 - -------------------------------------------------------------------------------- VALUE SHARES SEE NOTE 1 - ----------------------------------------------------------------------- COMMON STOCKS--99.4% - ----------------------------------------------------------------------- CONSUMER DISCRETIONARY--19.8% - ----------------------------------------------------------------------- HOTELS, RESTAURANTS & LEISURE--2.5% Cheesecake Factory, Inc.

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 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 34 | OPPENHEIMER MIDCAP FUND such principal exchange at its trading session ending at, or most recently prior to, the time when the Fund's assets are valued. Securities (including restricted securities) for which market quotations are not readily available are valued at their fair value. Foreign and domestic securities whose values have been materially affected by what the Manager identifies as a significant event occurring before the Fund's assets are valued but after the close of their respective exchanges will be fair valued. Fair value is determined in good faith using consistently applied procedures under the supervision of the Board of Trustees. Short-term "money market type" debt securities with remaining maturities of sixty days or less are valued at amortized cost (which approximates market value). - -------------------------------------------------------------------------------- JOINT REPURCHASE AGREEMENTS. Pursuant to an Exemptive Order issued by the Securities and Exchange Commission, the Fund, along with other affiliated funds advised by the Manager, may transfer uninvested cash balances into joint trading accounts on a daily basis. These balances are invested in one or more repurchase agreements. Securities pledged as collateral for repurchase agreements are held by a custodian bank until the agreements mature. Each agreement requires that the market value of the collateral be sufficient to cover payments of interest and principal. In the event of default by the other party to the agreement, retention of the collateral may be subject to legal proceedings. - -------------------------------------------------------------------------------- ALLOCATION OF INCOME, EXPENSES, GAINS AND LOSSES. Income, expenses (other than those attributable to a specific class), gains and losses are allocated on a daily basis to each class of shares based upon the relative proportion of net assets represented by such class. Operating expenses directly attributable to a specific class are charged against the operations of that class. - -------------------------------------------------------------------------------- FEDERAL TAXES. The Fund intends to comply with provisions of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its investment company taxable income, including any net realized gain on investments not offset by capital loss carryforwards, if any, to shareholders, therefore, no federal income or excise tax provision is required. The tax components of capital shown in the table below represent distribution requirements the Fund must satisfy under the income tax regulations, losses the Fund may be able to offset against income and gains realized in future years and unrealized appreciation or depreciation of securities and other investments for federal income tax purposes. 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 -------------------------------------------------------------------------- $-- $-- $1,064,638,023 $258,835,713 1. As of October 31, 2005, the Fund had $1,064,638,023 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, 2005, details of the capital loss carryforwards were as follows: 35 | OPPENHEIMER MIDCAP FUND NOTES TO FINANCIAL STATEMENTS Continued - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 1. SIGNIFICANT ACCOUNTING POLICIES Continued EXPIRING -------------------------- 2009 $ 759,109,628 2010 237,892,098 2011 67,636,297 -------------- TOTAL $1,064,638,023 ============== 2. During the fiscal year ended October 31, 2005, the Fund utilized $61,371,387 of capital loss carryforward to offset capital gains realized in that fiscal year. 3. During the fiscal year ended October 31, 2004, the Fund utilized $93,361,075 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, 2005. 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 ------------------------------------------------------ $12,924,131 $13,445,451 $521,320 No distributions were paid during the years ended October 31, 2005 and October 31, 2004. 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, 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 $ 878,724,748 ============== Gross unrealized appreciation $ 280,919,532 Gross unrealized depreciation (22,083,819) -------------- Net unrealized appreciation $ 258,835,713 ============== - -------------------------------------------------------------------------------- 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, 2005, the Fund's projected benefit obligations were decreased by $8,812 and payments of $4,152 were made to retired trustees, resulting in an accumulated liability of $145,312 as of October 31, 2005. 36 | OPPENHEIMER MIDCAP FUND The Board of Trustees has adopted a deferred compensation plan for independent trustees that enables trustees to elect to defer receipt of all or a portion of the annual compensation they are entitled to receive from the Fund. For purposes of determining the amount owed to the Trustee under the plan, deferred amounts are treated as though equal dollar amounts had been invested in shares of the Fund or in other Oppenheimer funds selected by the Trustee. The Fund purchases shares of the funds selected for deferral by the Trustee in amounts equal to his or her deemed investment, resulting in a Fund asset equal to the deferred compensation liability. Such assets are included as a component of "Other" within the asset section of the Statement of Assets and Liabilities. Deferral of trustees' fees under the plan will not affect the net assets of the Fund, and will not materially affect the Fund's assets, liabilities or net investment income per share. Amounts will be deferred until distributed in accordance to the Plan. - -------------------------------------------------------------------------------- DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions to shareholders, which are determined in accordance with income tax regulations, are recorded on the ex-dividend date. Income and capital gain distributions, if any, are declared and paid annually. - -------------------------------------------------------------------------------- INVESTMENT INCOME. Dividend income is recorded on the ex-dividend date or upon ex-dividend notification in the case of certain foreign dividends where the ex-dividend date may have passed. Non-cash dividends included in dividend income, if any, are recorded at the fair market value of the securities received. Interest income, which includes accretion of discount and amortization of premium, is accrued as earned. - -------------------------------------------------------------------------------- CUSTODIAN FEES. Custodian Fees and Expenses in the Statement of Operations may include interest expense incurred by the Fund on any cash overdrafts of its custodian account during the period. Such cash overdrafts may result from the effects of failed trades in portfolio securities and from cash outflows resulting from unanticipated shareholder redemption activity. The Fund pays interest to its custodian on such cash overdrafts 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. - -------------------------------------------------------------------------------- SECURITY TRANSACTIONS. Security transactions are recorded on the trade date. Realized gains and losses on securities sold are determined on the basis of identified cost. - -------------------------------------------------------------------------------- OTHER. The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates. 37 | OPPENHEIMER MIDCAP FUND NOTES TO FINANCIAL STATEMENTS Continued - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 2.

The Fund pays the Manager a fee of $1,500 per year for preparing and filing the Fund's tax returns. - -------------------------------------------------------------------------------- TRANSFER AGENT FEES. 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, 2005, the Fund paid $3,710,067 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 quarterly at an annual rate of up to 0.25% of the average annual net assets of Class A shares of the Fund. The Distributor currently uses all of those fees to pay dealers, brokers, banks and other financial institutions quarterly for providing personal services and maintenance of accounts of their customers that hold Class A shares. Any unreimbursed expenses the Distributor incurs with respect to Class A shares in any fiscal year cannot be recovered in subsequent years. Fees incurred by the Fund under the plan are detailed in the Statement of Operations. - -------------------------------------------------------------------------------- DISTRIBUTION AND SERVICE PLANS FOR CLASS B, CLASS C AND CLASS N SHARES. The Fund has adopted Distribution and Service Plans for Class B, Class C and Class N shares to compensate the Distributor for its services in connection with the distribution of those shares and servicing accounts. Under the plans, the Fund pays the Distributor an annual asset-based sales charge of 0.75% on Class B and Class C shares and 0.25% on Class N shares. The Distributor also receives a service fee of 0.25% per year under each plan. If either the Class B, Class C or Class N plan is terminated by the Fund or by the shareholders of a class, the Board of Trustees and its independent trustees must determine whether the Distributor shall be entitled to payment from the Fund of all or a portion of the service fee and/or asset-based sales charge in respect to shares sold prior to the effective date of such termination. The Distributor's aggregate uncompensated expenses under the plan at October 31, 2005 for Class B, Class C and Class N shares were $16,443,602, $4,410,856 and $487,197, respectively. Fees incurred by the Fund under the plans are detailed in the Statement of Operations. - -------------------------------------------------------------------------------- SALES CHARGES. Front-end sales charges and contingent deferred sales charges (CDSC) do not represent expenses of the Fund. They are deducted from the proceeds of sales of Fund shares prior to investment or from redemption proceeds prior to remittance, 39 | OPPENHEIMER MIDCAP FUND NOTES TO FINANCIAL STATEMENTS Continued - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- 4.

ILLIQUID OR RESTRICTED SECURITIES As of October 31, 2005, investments in securities included issues that are illiquid or restricted. Restricted securities are purchased in private placement transactions, are not registered under the Securities Act of 1933, may have contractual restrictions on resale, and are valued under methods approved by the Board of Trustees as reflecting fair value. A security may also be considered illiquid if it lacks a readily available market or if its valuation has not changed for a certain period of time. The Fund will not invest more than 10% of its net assets (determined at the time of purchase and reviewed periodically) in illiquid or restricted securities. Certain restricted securities, eligible for resale to qualified institutional investors, are not subject to that limitation. Securities that are illiquid or restricted are marked with the applicable footnote on the Statement of Investments. Information concerning restricted securities is as follows: VALUATION AS OF ACQUISITION OCTOBER 31, UNREALIZED SECURITY DATES COST 2005 DEPRECIATION - ---------------------------------------------------------------------------------------------------- Centerpoint Broadband Technologies, Inc., Cv., Series D 10/23/00 $ 5,999,997 $ -- $ 5,999,997 ITF Optical Technologies, Inc. 4/7/00 5,000,000 125,000 4,875,000 ----------------------------------------------- $ 10,999,997 $125,000 $ 10,874,997 =============================================== 40 | OPPENHEIMER MIDCAP FUND - -------------------------------------------------------------------------------- 6. 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. 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, 2005, 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, 2005, by correspondence with the custodian. 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, 2005, 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 FUND'S STATEMENT OF ADDITIONAL INFORMATION CONTAINS ADDITIONAL INFORMATION ABOUT THE FUND'S TRUSTEES AND OFFICERS AND IS AVAILABLE WITHOUT CHARGE UPON REQUEST, BY CALLING 1.800.525.7048. 47 | OPPENHEIMER MIDCAP FUND ITEM 2. CODE OF ETHICS. The registrant has adopted a code of ethics that applies to the registrant's principal executive officer, principal financial officer, principal accounting officer or controller or persons performing similar functions. ITEM 3. AUDIT COMMITTEE FINANCIAL EXPERT. The Board of Trustees of the registrant has determined that the registrant does not have an audit committee financial expert serving on its Audit Committee. In this regard, no member of the Audit Committee was identified as having all of the technical attributes identified in Instruction 2(b) to Item 3 of Form N-CSR to qualify as an "audit committee financial expert," whether through the type of specialized education or experience described in that Instruction. The Board has concluded that while the members of the Audit Committee collectively have the necessary attributes and experience required to serve effectively as an Audit Committee, no single member possesses all of the required technical attributes through the particular methods of education or experience set forth in the Instructions to be designated as an audit committee financial expert. ITEM 4. PRINCIPAL ACCOUNTANT FEES AND SERVICES. (a) Audit Fees The principal accountant for the audit of the registrant's annual financial statements billed $17,000 in fiscal 2005 and $15,000 in fiscal 2004. (b) Audit-Related Fees The principal accountant for the audit of the registrant's annual financial statements billed no such fees during the last two fiscal years. The principal accountant for the audit of the registrant's annual financial statements billed $156,805 in fiscal 2005 and $39,500 in fiscal 2004 to the registrant's investment adviser or any entity controlling, controlled by, or under common control with the adviser that provides ongoing services to the registrant. Such services: internal control reviews. (c) Tax Fees The principal accountant for the audit of the registrant's annual financial statements billed no such fees during the last two fiscal years. The principal accountant for the audit of the registrant's annual financial statements billed $5,000 in fiscal 2005 and $6,000 in fiscal 2004 to the registrant's investment adviser or any entity controlling, controlled by, or under common control with the adviser that provides ongoing services to the registrant. Such services: Computations of capital gain tax liability, preparation of tax returns, preparation of Form 5500 and tax consultations on pass through of foreign withholding taxes and mortgage dollar roll transactions. (d) All Other Fees The principal accountant for the audit of the registrant's annual financial statements billed no such fees in fiscal 2005 and $103 in fiscal 2004. Such services: the cost to the principal accountant of attending audit committee meetings. The principal accountant for the audit of the registrant's annual financial statements billed no such fees during the last two fiscal years to the registrant's investment adviser or any entity controlling, controlled by, or under common control with the adviser that provides ongoing services to the registrant. (e) (1) During its regularly scheduled periodic meetings, the registrant's audit committee will pre-approve all audit, audit-related, tax and other services to be provided by the principal accountants of the registrant. The audit committee has delegated pre-approval authority to its Chairman for any subsequent new engagements that arise between regularly scheduled meeting dates provided that any fees such pre-approved are presented to the audit committee at its next regularly scheduled meeting. Under applicable laws, pre-approval of non-audit services maybe waived provided that: 1) the aggregate amount of all such services provided constitutes no more than five percent of the total amount of fees paid by the registrant to it principal accountant during the fiscal year in which services are provided 2) such services were not recognized by the registrant at the time of engagement as non-audit services and 3) such services are promptly brought to the attention of the audit committee of the registrant and approved prior to the completion of the audit. (2) 100% (f) Not applicable as less than 50%. (g) The principal accountant for the audit of the registrant's annual financial statements billed $161,805 in fiscal 2005 and $45,603 in fiscal 2004 to the registrant and the registrant's investment adviser or any entity controlling, controlled by, or under common control with the adviser that provides ongoing services to the registrant related to non-audit fees. Those billings did not include any prohibited non-audit services as defined by the Securities Exchange Act of 1934. The registrant's audit committee of the board of trustees has considered whether the provision of non-audit services that were rendered to the registrant's investment adviser, and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with maintaining the principal accountant's independence.

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 October 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.
