FUND PERFORMANCE DISCUSSION
- --------------------------------------------------------------------------------

HOW HAS THE FUND PERFORMED? BELOW IS A DISCUSSION BY OPPENHEIMERFUNDS, INC., OF
THE FUND'S PERFORMANCE DURING ITS FISCAL YEAR ENDED OCTOBER 31, 2006, FOLLOWED
BY A GRAPHICAL COMPARISON OF THE FUND'S PERFORMANCE TO AN APPROPRIATE
BROAD-BASED MARKET INDEX.

MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE. For the 12-month period ending
October 31, 2006, Oppenheimer MidCap Fund's Class A shares (without sales
charge) produced positive results but underperformed its benchmark, the S&P
MidCap 400 Index. We attribute this relative underperformance to the Fund's
focus on higher-quality companies during a market environment that predominantly
favored lower-quality companies.

      In terms of industries, top contributors included industrials and IT
services. The Fund's underweight in the energy and household durables areas also
benefited performance. In contrast, bottom-performers included the consumer
discretionary and healthcare sectors.

      Regardless of broader market trends, we continue to follow a bottom-up,
research driven stock selection strategy that emphasizes higher-quality
securities. We target those companies we believe offer strong balance sheets,
stable earnings, sustainable growth rates and accomplished management teams. Due
to the Fund's focus on higher-quality stocks, the Fund tends to be negatively
impacted during investment environments that favor more speculative stocks, as
evidenced over the reporting period. Historically, during the end stages of a
bull market, many investors' appetite for risk increases and they tend to focus
on lower-quality companies in their pursuit of gaining higher investment
returns. As a result of this cyclical event, higher-quality companies, those
with strong balance sheets, stable earnings and sustainable growth rates, tend
to underperform. However, when economic growth slows, investors usually become
risk adverse and shift assets to higher-quality stocks, in which case
higher-quality issuers tend to outperform.

      Over the period we made a few notable adjustments to the Fund's sector
weightings. For example, we significantly decreased the Fund's exposure to the
consumer discretionary sector, primarily due to our concerns over slower
economic growth. We also reduced the Fund's weighting to the energy sector. We
believe companies in this space will begin to show a deceleration in their
earnings growth as commodity prices have started to weaken. Additionally, we
greatly increased the Fund's weighting to the financials sector. Over the next
18 months, we believe the current inverted yield curve will steepen, which
should benefit the Fund's financial securities.

      On the negative side of performance, in addition to higher quality stocks
falling out of favor, a number of individual holdings significantly detracted
from performance. In the consumer discretionary sector, specialty-retailers and
media stocks hurt results. Within specialty retailers, both Chico's FAS, Inc.
and Williams-Sonoma, Inc., suffered, as investors grew concerned over a slowdown
in consumer spending due to increasing oil prices. In


                          10 | OPPENHEIMER MIDCAP FUND


the media area, Getty Images, Inc., a leading provider of imagery, film and
digital services, declined as the company's business fundamentals deteriorated.
Also underperforming was NAVTEQ Corp., a manufacturer of digital maps used in
vehicle navigation systems. The company's sales were adversely affected as
higher oil prices negatively impacted the auto manufacturing industry, NAVTEQ's
primary customer. Top detractors in the healthcare sector included The Cooper
Companies, Inc., and PDL BioPharma, Inc. The Cooper Companies, Inc., a
manufacturer and marketer of specialty healthcare products, lost significant
market share as it failed to execute on its new contact lens product.
Biotechnology firm, PDL BioPharma, Inc., declined as it delayed a new product
launch and announced significantly higher costs to develop clinical drug trials.
As a result of the fundamental problems these securities incurred, we eliminated
all six of these stocks from the portfolio.

      On the positive side, top contributions to performance came predominantly
from securities within the industrials and technology sectors. Within
industrials the best performers were Expeditors International of Washington,
Inc., a freight forwarding company and Fastenal Co., a nuts and bolts
distributor. Both companies outperformed due to a strong global economy, which
drove up demand for their respective services and products. In the technology
sector, strong performance came from IT services providers Cognizant Technology
Solutions Corp., an offshore outsourcing IT services provider and Alliance Data
Systems Corp., a provider of transaction, credit and marketing services. Both
companies continued to benefit from the strong outsourcing trend and delivered
very favorable earnings results. Additionally, fashion retailer, Polo Ralph
Lauren Corp. bucked the negative trend that overshadowed the specialty retail
market by successfully managing its brand, which led to higher than expected
sales. Lastly, the Fund benefited from its underweight in the energy and
household durables areas. Both areas declined due to volatile commodity 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, 2006. 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

FUND PERFORMANCE DISCUSSION

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 Mid-Cap 400 Index.
The S&P Mid-Cap 400 Index is an unmanaged index of 400 domestic stocks chosen
for market size 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.

THE PERFORMANCE DATA QUOTED REPRESENTS PAST PERFORMANCE, WHICH DOES NOT
GUARANTEE FUTURE RESULTS. THE INVESTMENT RETURN AND PRINCIPAL VALUE OF AN
INVESTMENT IN THE FUND WILL FLUCTUATE SO THAT AN INVESTOR'S SHARES, WHEN
REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST. CURRENT
PERFORMANCE MAY BE LOWER OR HIGHER THAN THE PER-FORMANCE QUOTED. FOR PERFORMANCE
DATA CURRENT TO THE MOST RECENT MONTH END, VISIT US AT WWW.OPPENHEIMERFUNDS.COM,
OR CALL US AT 1.800.525.7048. FUND RETURNS INCLUDE CHANGES IN SHARE PRICE,
REINVESTED DISTRIBUTIONS, AND THE APPLICABLE SALES CHARGE: FOR CLASS A SHARES,
THE CURRENT MAXIMUM INITIAL SALES CHARGE OF 5.75%; FOR CLASS B SHARES, THE
CON-TINGENT DEFERRED SALES CHARGE OF 5% (1-YEAR) AND 2% (5-YEAR); AND FOR CLASS
C AND N SHARES, THE CONTINGENT 1% DEFERRED SALES CHARGE FOR THE 1-YEAR PERIOD.
THERE IS NO SALES CHARGE FOR CLASS Y SHARES. 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. SEE PAGE 18 FOR
FURTHER INFORMATION.

AVERAGE ANNUAL TOTAL RETURNS OF CLASS Y SHARES OF THE FUND AT 10/31/06

THE PERFORMANCE DATA QUOTED REPRESENTS PAST PERFORMANCE, WHICH DOES NOT
GUARANTEE FUTURE RESULTS. THE INVESTMENT RETURN AND PRINCIPAL VALUE OF AN
INVESTMENT IN THE FUND WILL FLUCTUATE SO THAT AN INVESTOR'S SHARES, WHEN
REDEEMED, MAY BE WORTH MORE OR LESS THAN THEIR ORIGINAL COST. CURRENT
PERFORMANCE MAY BE LOWER OR HIGHER THAN THE PER-FORMANCE QUOTED. FOR PERFORMANCE
DATA CURRENT TO THE MOST RECENT MONTH END, VISIT US AT WWW.OPPENHEIMERFUNDS.COM,
OR CALL US AT 1.800.525.7048. FUND RETURNS INCLUDE CHANGES IN SHARE PRICE,
REINVESTED DISTRIBUTIONS, AND THE APPLICABLE SALES CHARGE: FOR CLASS A SHARES,
THE CURRENT MAXIMUM INITIAL SALES CHARGE OF 5.75%; FOR CLASS B SHARES, THE
CON-TINGENT DEFERRED SALES CHARGE OF 5% (1-YEAR) AND 2% (5-YEAR); AND FOR CLASS
C AND N SHARES, THE CONTINGENT 1% DEFERRED SALES CHARGE FOR THE 1-YEAR PERIOD.
THERE IS NO SALES CHARGE FOR CLASS Y SHARES. 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. SEE PAGE 18 FOR
FURTHER INFORMATION.

NOTES
- --------------------------------------------------------------------------------

Total returns and the ending account values in the graphs include changes in
share price and reinvestment of dividends and capital gains distributions in a
hypothetical investment for the periods shown. 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.

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, 2006.

ACTUAL EXPENSES. The "actual" lines of the table provide information about
actual account values and actual expenses. You may use the information on this
line for the class of shares you hold, together with the amount you invested, to
estimate the expense that you paid over the period. Simply divide your account
value by $1,000.00 (for example, an $8,600.00 account value divided by $1,000.00
= 8.60), then multiply the result by the number in the "actual" line under the
heading entitled "Expenses Paid During Period" to estimate the expenses you paid
on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES. The "hypothetical" lines of the
table provide information about hypothetical account values and hypothetical
expenses based on the Fund's actual expense ratio for each class of shares, and
an assumed rate of return of 5% per year before expenses, which is not the
Fund's actual return. The hypothetical account values and expenses may not be
used to estimate the actual ending account balance or expenses you paid for the
period. You may use this information to compare the ongoing costs of investing
in the Fund and other funds. To do so, compare this 5% hypothetical example for
the class of shares you hold with the 5% hypothetical examples that appear in
the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as front-end
or contingent deferred sales charges (loads), or a $12.00 fee imposed annually
on accounts valued at less than $500.00 (subject to exceptions described in


                          20 | 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.

Class Y Hypothetical            1,000.00         1,020.82         4.44

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 affiliated fund indirect expenses, based on the 6-month period ended
October 31, 2006 are as follows:

CLASS       EXPENSE RATIOS
- --------------------------
Class A          1.28%
- --------------------------
Class B          2.01
- --------------------------
Class C          2.02
- --------------------------
Class N          1.53
- --------------------------
Class Y          0.87

The expense ratios reflect voluntary waivers or reimbursements of expenses 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.

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
exch-ange 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


                          34 | OPPENHEIMER MIDCAP FUND


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. Investments in open-end
registered investment companies 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).

- --------------------------------------------------------------------------------
AFFILIATED FUNDS. The Fund is permitted to invest daily available cash balances
in affiliated money market funds. Each day, the Fund invests the available cash
in Oppenheimer Institutional Money Market Fund ("IMMF") which seeks current
income and stability of principal. The Manager is also the investment advisor of
IMMF. The Fund's investment in IMMF is included in the Statement of Investments.
Included in the net earnings received from IMMF is a 0.10% management fee paid
to the Manager by IMMF. 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 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.

1. As of October 31, 2006, the Fund had $966,835,868 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, 2006,
details of the capital loss carryforwards were as follows:

of capital loss carryforward to offset capital gains realized in that fiscal
year. a

      September 4, 2003 merger of Oppenheimer Select Managers-Gartmore
      Millennium Growth Fund II.

      September 4, 2003 merger of Oppenheimer Select Managers-Gartmore

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, 2006. Net assets of the
Fund were unaffected by the reclassifications.

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, 2006 are noted below. The primary
difference between book and tax appreciation or depreciation of securities and

                          36 | OPPENHEIMER MIDCAP FUND


- --------------------------------------------------------------------------------
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, 2006, the Fund's projected benefit obligations were increased by $6,211 and
payments of $6,772 were made to retired trustees, resulting in an accumulated
liability of $144,751 as of October 31, 2006.

      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 defer-ral 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 mat-erially affect the Fund's assets, liabilities or net
investment in-come 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 sec-urities and from cash outflows
resulting from unanticipated shareholder redemption activity. The Fund pays
interest to its custodian on such cash over-drafts, 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.

- --------------------------------------------------------------------------------
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.

1. SIGNIFICANT ACCOUNTING POLICIES Continued

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.

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 up to 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,
2006 for Class B, Class C and Class N shares were $16,589,015, $4,731,847 and
$663,583, respectively. Fees incurred by the Fund under the plans are detailed
in the Statement of Operations.

SALES CHARGES. Front-end sales charges and contingent deferred sales charges
(CDSC) do not represent expenses of the Fund. They are deducted from the
proceeds of sales of Fund shares prior to investment or from redemption proceeds
prior to remittance, as applicable. The sales charges retained by the
Distributor from the sale of shares and the CDSC retained by the Distributor on
the redemption of shares is shown in the following table for the period
indicated.

5. RECENT ACCOUNTING PRONOUNCEMENTS

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 accoun-ting 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, 2006, the Manager is evaluating the implications of FIN 48. Its
impact in the Fund's financial statements has not yet been determined.

      In September 2006, the Financial Accounting Standards Board 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, 2006, 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. LITIGATION

A consolidated amended complaint was filed as a putative class action against
the Manager and the Transfer Agent and other defendants (including 51 of the
Oppenheimer funds including the Fund) in the U.S. District Court for the
Southern District of New York on January 10, 2005 and was amended on March 4,
2005. The complaint alleged, among other things, that the Manager charged
excessive fees for distribution and other costs, and that by permitting and/or
participating in those actions, the Directors/Trustees and the Officers of the
funds breached their fiduciary duties to fund shareholders under the Investment
Company Act of 1940 and at common law. The plaintiffs sought unspecified
damages, an accounting of all fees paid, and an award of attorneys' fees and
litigation expenses.

      In response to the defendants' motions to dismiss the suit, seven of the
eight counts in the complaint, including the claims against certain of the
Oppenheimer funds, as nominal defendants, and against certain present and former
Directors, Trustees and Officers of the funds, and the Distributor, as
defendants, were dismissed with prejudice, by court order dated March 10, 2006,
and the remaining count against the Manager and the Transfer Agent was dismissed
with prejudice by court order dated April 5, 2006. The plaintiffs filed an
appeal of those dismissals on May 11, 2006.

6. LITIGATION Continued

      The Manager believes that the allegations contained in the complaint are
without merit and that there are substantial grounds to sustain the district
court's rulings. The Manager also believes that it is premature to render any
opinion as to the likelihood of an outcome unfavorable to it, the funds, the
Directors/Trustees or the Officers on the appeal of the decisions of the
district court, and that no estimate can yet be made with any degree of
certainty as to the amount or range of any potential loss.

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, 2006, 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, 2006, 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, 2006, 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 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, 2006, 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.

      (2) Exhibits attached hereto.

      (3) Not applicable.

(b)   Exhibit attached hereto.




                                   SIGNATURES

Pursuant to the requirements of the Securities Exchange Act of 1934 and the
Investment Company Act of 1940, the registrant has duly caused this report to be
signed on its behalf by the undersigned, thereunto duly authorized.
