Cumulative total returns are not annualized. 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. 10 | OPPENHEIMER MIDCAP FUND 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. 11 | 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 April 30, 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 12 | OPPENHEIMER MIDCAP FUND 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 (11/1/04) (4/30/05) APRIL 30, 2005 - ------------------------------------------------------------------------------ Class A Actual $1,000.00 $1,033.20 $ 6.78 - ------------------------------------------------------------------------------ Class A Hypothetical 1,000.00 1,018.15 6.73 - ------------------------------------------------------------------------------ Class B Actual 1,000.00 1,029.40 10.77 - ------------------------------------------------------------------------------ Class B Hypothetical 1,000.00 1,014.23 10.69 - ------------------------------------------------------------------------------ Class C Actual 1,000.00 1,029.40 10.62 - ------------------------------------------------------------------------------ Class C Hypothetical 1,000.00 1,014.38 10.54 - ------------------------------------------------------------------------------ Class N Actual 1,000.00 1,032.20 7.84 - ------------------------------------------------------------------------------ Class N Hypothetical 1,000.00 1,017.11 7.78 - ------------------------------------------------------------------------------ Class Y Actual 1,000.00 1,035.50 4.60 - ------------------------------------------------------------------------------ Class Y Hypothetical 1,000.00 1,020.28 4.57 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 181/365 (to reflect the one-half year period). Those annualized expense ratios based on the 6-month period ended April 30, 2005 are as follows: CLASS EXPENSE RATIOS - --------------------------------------------- Class A 1.34% - --------------------------------------------- Class B 2.13 - --------------------------------------------- Class C 2.10 - --------------------------------------------- Class N 1.55 - --------------------------------------------- Class Y 0.91 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. - -------------------------------------------------------------------------------- 13 | OPPENHEIMER MIDCAP FUND STATEMENT OF INVESTMENTS April 30, 2005 / Unaudited - -------------------------------------------------------------------------------- VALUE SHARES SEE NOTE 1 - -------------------------------------------------------------------------------- COMMON STOCKS-99.2% - -------------------------------------------------------------------------------- CONSUMER DISCRETIONARY-23.3% - -------------------------------------------------------------------------------- AUTO COMPONENTS-1.2% Gentex Corp. 364,500 $ 11,831,670 - -------------------------------------------------------------------------------- AUTOMOBILES-0.6% Harley-Davidson, Inc. 132,200 6,216,044 - -------------------------------------------------------------------------------- HOTELS, RESTAURANTS & LEISURE-5.2% Cheesecake Factory, Inc.

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 listed or traded on National Stock Exchanges or other domestic or foreign exchanges are valued based on the last sale price of the security traded on that exchange prior to the time when the Fund's assets are valued. Securities traded on NASDAQ are valued based on the closing price provided by NASDAQ prior to the time when the Fund's assets are valued. In the absence of a sale, the security is valued at the last sale price on the prior trading day, if it is within the spread of the closing "bid" and "asked" prices, and if not, at the closing bid price. Corporate, government and municipal debt instruments having a remaining maturity in excess of sixty days and all mortgage-backed securities will be valued at the mean between the "bid" and "asked" prices. Futures contracts traded on a commodities or futures exchange will be valued at the final settlement price or official closing price on the principal exchange as reported by such principal exchange at its trading session ending at, or most recently prior to, the time when the Fund's assets are valued. Securities may be valued primarily using dealer-supplied valuations or a portfolio pricing service authorized by the Board of Trustees. Securities (including restricted securities) for which market quotations are not readily available are valued at their fair value. Foreign and domestic securities whose values have been materially affected by what the Manager 26 | OPPENHEIMER MIDCAP FUND 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). Reported net realized foreign exchange gains or losses arise from sales of portfolio securities, sales and maturities of short-term securities, sales of foreign currencies, currency gains or losses realized between the trade and settlement dates on securities transactions, and the difference between the amounts of dividends, interest, and foreign withholding taxes recorded on the Fund's books and the U.S. dollar equivalent of the amounts actually received or paid. Net unrealized foreign exchange gains and losses arise from changes in the values of assets and liabilities, including investments in securities at fiscal period end, resulting from changes in exchange rates. The effect of changes in foreign currency exchange rates on investments is separately identified from the fluctuations arising from changes in market values of securities held and reported with all other foreign currency gains and losses in the Fund's Statement of Operations. - -------------------------------------------------------------------------------- JOINT REPURCHASE AGREEMENTS. Pursuant to an Exemptive Order issued by the Securities and Exchange Commission, the Fund, along with other affiliated funds advised by the Manager, may transfer uninvested cash balances into joint trading accounts on a daily basis. These balances are invested in one or more repurchase agreements. Securities pledged as collateral for repurchase agreements are held by a custodian bank until the agreements mature. Each agreement requires that the market value of the collateral be sufficient to cover payments of interest and principal. In the event of default by the other party to the agreement, retention of the collateral may be subject to legal proceedings. - -------------------------------------------------------------------------------- ALLOCATION OF INCOME, EXPENSES, GAINS AND LOSSES. Income, expenses (other than those attributable to a specific class), gains and losses are allocated on a daily basis to each class of shares based upon the relative proportion of net assets represented by such class. Operating expenses directly attributable to a specific class are charged against the operations of that class. - -------------------------------------------------------------------------------- FEDERAL TAXES. The Fund intends to comply with provisions of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its investment company taxable income, including any net realized gain on investments not offset by capital loss carryforwards, if any, to shareholders, therefore, no federal income or excise tax provision is required. 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. 27 | OPPENHEIMER MIDCAP FUND NOTES TO FINANCIAL STATEMENTS Unaudited / Continued - -------------------------------------------------------------------------------- 1. SIGNIFICANT ACCOUNTING POLICIES Continued As of April 30, 2005, the Fund had available for federal income tax purposes an estimated capital loss carryforward of $1,093,809,366. This estimated capital loss carryforward represents carryforward as of the end of the last fiscal year, increased for losses deferred under tax accounting rules to the current fiscal year and is increased or decreased by capital losses or gains realized in the first six months of the current fiscal year. As of April 30, 2005, it is estimated that the Fund will utilize $31,939,384 of capital loss carryforward to offset realized capital gains. During the year ended October 31, 2004, the Fund utilized $93,361,075 of capital loss carryforward to offset capital gains realized in that fiscal year. As of October 31, 2004, the Fund had available for federal income tax purposes unused capital loss carryforwards as follows: EXPIRING ----------------------------- 2008 $ 54,968,709 2009 765,251,646 2010 237,892,098 2011 67,636,297 --------------- Total $ 1,125,748,750 =============== - -------------------------------------------------------------------------------- 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 six months ended April 30, 2005, the Fund's projected benefit obligations were increased by $2,678 and payments of $4,153 were made to retired trustees, resulting in an accumulated liability of $156,801 as of April 30, 2005. 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. 28 | OPPENHEIMER MIDCAP FUND - -------------------------------------------------------------------------------- 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. - -------------------------------------------------------------------------------- 2.

The Fund has adopted a Service Plan for Class A 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 April 30, 2005 for Class B, Class C and Class N shares were $16,298,528, $3,918,277 and $452,062, respectively.

ILLIQUID OR RESTRICTED SECURITIES As of April 30, 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: ACQUISITION VALUATION AS OF UNREALIZED SECURITY DATES COST APRIL 30, 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 5,000,000 173,606 4,826,394 - -------------------------------------------------------------------------------- 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. 32 | OPPENHEIMER MIDCAP FUND PORTFOLIO PROXY VOTING POLICIES AND PROCEDURES; UPDATES TO STATEMENTS OF INVESTMENTS Unaudited - -------------------------------------------------------------------------------- - -------------------------------------------------------------------------------- The Fund has adopted Portfolio Proxy Voting Policies and Procedures under which the Fund votes proxies relating to securities ("portfolio proxies") held by the Fund.

The Investment Company Act of 1940, as amended, requires that the Board request and evaluate, and that the Manager provide, such information as may be reasonably necessary to evaluate the terms of the advisory agreement. The Board employs an independent consultant to prepare a report that provides information, including comparative information, that the Board requests for this purpose. In addition, the Board receives information throughout the year regarding Fund services, fees, expenses and performance. NATURE AND EXTENT OF SERVICES. In considering the renewal of the Fund's advisory agreement for the current year, the Board evaluated the nature and extent of the services provided by the Manager and its affiliates. The Manager provides the Fund with office space, facilities and equipment; administrative, accounting, clerical, legal and compliance personnel; securities trading services; oversight of third party service providers and the services of the portfolio manager and the Manager's investment team, who provide research, analysis and other advisory services in regard to the Fund's investments. QUALITY OF SERVICES. The Board also considered the quality of the services provided and the quality of the Manager's resources that are available to the Fund. The Board noted that the Manager has had over forty years of experience as an investment adviser and that its assets under management rank it among the top mutual fund managers in the United States. The Board evaluated the Manager's administrative, accounting, legal and compliance services and information the Board received regarding the experience and professional qualifications of the Manager's personnel and the size and functions of its staff. The Board members also considered their experiences as directors or trustees of the Fund and other funds advised by the Manager. The Board received and reviewed information regarding the quality of services provided by affiliates of the Manager, which it also reviews at other times during the year in connection with the renewal of the Fund's service agreements. The Board noted that the relatively low redemption rate for funds advised by the Manager provided an indication of shareholder satisfaction with the overall level of services provided by the Manager. PORTFOLIO MANAGEMENT SERVICES AND PERFORMANCE. In its evaluation of the quality of the portfolio management services provided, the Board considered the experience of John O'Hare and the Manager's Growth Equity investment team and analysts. Mr. O'Hare has had over 17 years of experience managing equity investments and has been primarily responsible for the day-to-day management of the Fund's portfolio since October 29, 2003. Mr. O'Hare, a Chartered Financial Analyst, has been a Vice President of the Manager since September 2003 and was Executive Vice President and Portfolio Manager from June 34 | OPPENHEIMER MIDCAP FUND 2000 through August 2003 and Portfolio Manager and Senior Vice President from August 1997 through June 2000 at Geneva Capital Management, Ltd.. He is an officer of two portfolios in the OppenheimerFunds complex. The Board 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 mid-cap growth funds (including both funds advised by the Manager and funds advised by other investment advisers). The Board also receives and reviews comparative performance information regarding the Fund and other funds at each Board meeting. The Board noted that the Fund's one-year performance was slightly better than its peer group average. However its three- and five-year performance was disappointing. MANAGEMENT FEES AND EXPENSES. The Board also reviewed information, including comparative information, regarding the fees paid to the Manager and its affiliates and the other expenses borne by the Fund. The independent consultant provided comparative data in regard to the fees and expenses of the Fund, other mid-cap growth funds and other funds with comparable assets levels and distribution features. The Board noted that the Fund's contractual and actual management fees and its total expenses are all lower than its peer group average. In addition, the Board evaluated the comparability of the fees charged and the services provided to the Fund to the fees charged and services provided to other types of entities advised by the Manager. PROFITABILITY OF THE MANAGER AND AFFILIATES. The Board also reviewed information regarding the cost of services provided by the Manager and its affiliates and the Manager's profitability. The Board considered that the Manager must be able to pay and retain experienced professional personnel at competitive rates to provide services to the Fund and that maintaining the financial viability of the Manager is important in order for the Manager to continue to provide significant services to the Fund and its shareholders. In addition the Board considered information that was provided regarding the direct and indirect benefits the Manager receives as a result of its relationship with the Fund, including compensation paid to the Manager's affiliates and research provided to the Manager in connection with permissible brokerage arrangements (soft dollar arrangements). ECONOMIES OF SCALE. The Board reviewed the extent to which the Manager may realize economies of scale in managing and supporting the Fund and the current level of Fund assets in relation to the Fund's breakpoint schedule for its management fees. The Board noted that the fund has recently experienced moderate asset growth and that, based on current asset levels, the Fund is not yet approaching its last management fee breakpoint. 35 | OPPENHEIMER MIDCAP FUND BOARD APPROVAL OF THE FUND'S INVESTMENT ADVISORY AGREEMENT Unaudited / Continued - -------------------------------------------------------------------------------- CONCLUSIONS. These factors were also considered by the independent Trustees meeting separately from the full Board, assisted by experienced counsel to the Fund. Fund counsel is independent of the Manager within the meaning and intent of the Securities and Exchange Commission Rules. The Board was aware that there are alternatives to retaining the Manager. 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 investment advisory 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 advisory agreement, including the management fee, in light of all of the surrounding circumstances. 36 | OPPENHEIMER MIDCAP ITEM 2.

SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS The Board is responsible for approving nominees for election as trustees. To assist in this task, the Board has designated the Audit Committee as the nominating committee for the Board. It reviews and recommends nominees to the Board. The Committee is comprised entirely of disinterested trustees as defined in Section 2(a)(19) of the Investment Company Act of 1940. The Audit Committee charter describes the responsibilities of the Committee in nominating candidates for election as independent Trustees of the Registrant. The Registrant's Board has adopted a written charter for the Committee. A current copy of the Audit Committee charter is available to shareholders on the OppenheimerFunds website at WWW.OPPENHEIMERFUNDS.COM. Under the current policy, if the Board determines that a vacancy exists or is likely to exist on the Board, the Audit Committee of the Board will consider candidates for Board membership including recommended by Registrant shareholders. The Audit Committee will consider nominees recommended by independent Board members or recommended by any other Board members including Board members affiliated with the Registrant's investment advisors. The Committee may, upon Board approval, retain an executive search firm to assist in screening potential candidates. Upon Board approval, the Audit Committee may also use the services of legal, financial, or other external counsel that it deems necessary or desirable in the screening process. Shareholders wishing to submit a nominee for election to the Board may do so by mailing their submission to the offices of OppenheimerFunds, Inc., 6803 South Tucson Way, Centennial, CO 80112, to the attention of the Board of Trustees of the named Registrant, c/o the Secretary of the Registrant. The Committee's process for identifying and evaluating nominees for trustees includes a number of factors. In screening candidates for board membership, whether the candidate is suggested by Board members, shareholders or others, the Committee considers the candidate's professional experience, soundness of judgment, integrity, ability to make independent, analytical inquiries, collegiality, willingness and ability to devote the time required to perform Board activities adequately, ability to represent the interests of all shareholders of the Registrant, and diversity relative to the board's composition. Candidates are expected to provide a mix of attributes, experience, perspective and skills necessary to effectively advance the interests of shareholders. ITEM 11. CONTROLS AND PROCEDURES (a) Based on their evaluation of 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 April 30, 2005, registrant's principal executive officer and principal financial officer found registrant's disclosure controls and procedures to provide reasonable assurances that information required to be disclosed by 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.
