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, 2003, followed
by a graphical comparison of the Fund's performance to an appropriate
broad-based market index.

Management's Discussion of Fund Performance. Over the 12-month period ended
October 31, 2003, the Fund delivered positive results, posting a 22.22% return
for its Class A shares (without sales charge). This compares with a 30.73% total
return for the S&P Mid-Cap 400 Index, the Fund's benchmark, during the same
period. The Fund's performance was driven primarily by the upturn in growth
stock prices that began in March 2003 and continued throughout the remainder of
the period, representing a major shift from the downward-trending stock market
of the previous three years.

   Throughout the period, the Fund's investment strategy remained focused on
companies generating real growth by increasing sales and revenues, rather than
those experiencing a temporary rise in earnings from acquisitions, accounting
gimmicks or cost-cutting methods. Specifically, we targeted companies producing
greater-than-average earnings and revenue growth that we believed were
sustainable. This approach enabled us to control some of the risks implicit in
growth-oriented stock investing. We also maintained the Fund's disciplined focus
on mid-cap stocks. Many mid-cap stocks offer higher growth rates than most large
companies, and greater stability and predictability than most small ones. As a
result, we believe they offer higher probabilities of success and lower
probabilities of failure than other segments of the equities market. In our
opinion, these intrinsic characteristics make mid-cap stocks particularly
attractive for disciplined growth investors seeking to build wealth over the
long term.

   Early in the period, we found a relatively large number of attractive
investment opportunities meeting the Fund's investment criteria in the health
care area. Biotechnology holdings, such as Gilead Sciences, Inc., delivered
exceptionally strong performance during the period, supported by a rapidly
increasing number of approved products with wide applications. The Fund's
performance was also boosted by its investments in medical products companies,
such as Varian Medical Systems, Inc., and generic drug producers, many of which
benefited from significant new drug approvals.

   As the reporting period progressed, we found increasing numbers of technology
stocks exhibiting attractive fundamentals. Accordingly, we gradually shifted a
growing percentage of the Fund's assets into such stocks, reducing the Fund's
holdings among less attractive health care and financial investments. Although a
few technology holdings, such as Concord EFS, Inc., delivered disappointing
returns, most of the Fund's technology positions generated strong gains. Top
performers included software companies, such as Symantec Corp.; communications
services providers, such as UTStarcom, Inc.; and


                           6 | OPPENHEIMER MIDCAP FUND



semiconductor producers, such as Marvell Technology Group Ltd. The Fund also
achieved strong gains with its investments in consumer discretionary stocks,
particularly among media companies, such as InterActiveCorp, Univision
Communications, Inc.

   Positive returns from these and other consumer-related holdings more than
offset some of the Fund's disappointments. Negative contributors to performance
included restaurant fast food chain Wendy's International, Inc., and healthcare
software vendor Cerner Corp. Significant underperformers in other areas included
SPX Corp. and Alliant Techsystems, Inc. The Fund's portfolio holdings,
allocations and strategies are subject to change.

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, 2003. 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.

   The Fund's performance is compared to that of the S&P Mid-Cap 400 Index. The
S&P Mid-Cap 400 is an unmanaged index of 400 domestic stocks chosen for market
size liquidity, and industry group representation. Index performance reflects
the reinvestment of dividends but does not consider the effect of capital gains
or transaction costs, and none of the data in the graphs shows the effect of
taxes. The Fund's performance reflects the effects of Fund 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 securities in the index.

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


In reviewing performance, please remember that past performance cannot guarantee
future results. 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 the original cost. Because of ongoing market volatility, the
Fund's performance may be subject to substantial fluctuations, and current
performance may be more or less than the results shown. For updates on the
Fund's performance, visit our website at www.oppenheimerfunds.com.

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. For more complete information

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. All classes of shares have identical rights
and voting privileges. Earnings, net assets and net asset value per share may
differ by minor amounts due to each class having its own expenses directly
attributable to that class. Classes 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. 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. Securities (including restricted securities)
for which quotations are not readily available are valued primarily using
dealer-supplied valuations, a portfolio pricing service authorized by the Board
of Trustees, or at their fair value. 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).

- --------------------------------------------------------------------------------
Foreign Currency Translation. The Fund's accounting records are maintained in
U.S. dollars. Prices of securities denominated in foreign currencies are
translated into U.S. dollars at the closing rates of exchange. Amounts related
to the purchase and sale of foreign securities and investment income are
translated at the rates of exchange prevailing on the respective dates of such
transactions.
   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.

advised by the Manager, may transfer uninvested cash balances into joint trading
accounts on a daily basis. Secured by U.S. government securities, 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 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, 2003.
Net assets of the Fund were unaffected by the reclassifications.

No distributions were paid during the years ended October 31, 2003 and October
31, 2002.

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, 2003 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.

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, 2003, the Fund's projected benefit obligations were increased by $2,296 and
payments of $3,871 were made to retired trustees, resulting in an accumulated
liability of $146,496 as of October 31, 2003.
   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.
Under the plan, deferred amounts are treated as though equal dollar amounts had
been invested in shares of the Fund or are invested in other Oppenheimer funds
selected by the Trustee. 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.

NOTES TO FINANCIAL STATEMENTS  Continued
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
1. Significant Accounting Policies Continued
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.

- --------------------------------------------------------------------------------
Expense Offset Arrangement. The reduction of custodian fees represents earnings
on cash balances maintained by the Fund.

- --------------------------------------------------------------------------------
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 accounting
principles generally accepted in the United States of America 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.

5. Option Activity
The Fund may buy and sell put and call options, or write put and covered call
options on portfolio securities in order to produce incremental earnings or
protect against changes in the value of portfolio securities.
   The Fund generally purchases put options or writes covered call options to
hedge against adverse movements in the value of portfolio holdings. When an
option is written, the Fund receives a premium and becomes obligated to sell or
purchase the underlying security at a fixed price, upon exercise of the option.
   Options are valued daily based upon the last sale price on the principal
exchange on which the option is traded and unrealized appreciation or
depreciation is recorded. The Fund will realize a gain or loss upon the
expiration or closing of the option transaction. When an option is exercised,
the proceeds on sales for a written call option, the purchase cost for a written
put option, or the cost of the security for a purchased put or call option is
adjusted by the amount of premium received or paid.
   Securities designated to cover outstanding call options are noted in the
Statement of Investments where applicable. Shares subject to call, expiration
date, exercise price, premium received and market value are detailed in a note
to the Statement of Investments. Options written are reported as a liability in
the Statement of Assets and Liabilities. Realized gains and losses are reported
in the Statement of Operations.
   The risk in writing a call option is that the Fund gives up the opportunity
for profit if the market price of the security increases and the option is
exercised. The risk in writing a put option is that the Fund may incur a loss if
the market price of the security decreases and the option is exercised. The risk
in buying an option is that the Fund pays a premium whether or not the option is
exercised. The Fund also has the additional risk of not being able to enter into
a closing transaction if a liquid secondary market does not exist.

6. Illiquid or Restricted Securities
As of October 31, 2003, 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 intends to invest no more than
15% 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. The aggregate value of illiquid or restricted
securities subject to this limitation as of October 31, 2003 was $553,730, which
represents 0.06% of the Fund's net assets, all of which are considered
restricted. Information concerning restricted securities is as follows:

7. Acquisition of Oppenheimer Select Managers Gartmore Millennium Growth Fund II
On September 4, 2003, the Fund acquired all of the net assets of Oppenheimer
Select Managers Gartmore Millennium Growth Fund II, pursuant to an Agreement and
Plan of Reorganization approved by the Oppenheimer Select Managers Gartmore
Millennium Growth Fund II shareholders on August 29, 2003. The Fund issued (at
an exchange ratio of 0.525672 for Class A, 0.537854 for Class B, 0.538216 for
Class C, 0.524906 for Class N and 0.515156 for Class Y of the Fund to one share
of Oppenheimer MidCap Fund 317,478; 38,399; 33,708; 11,483 and 52 shares of
beneficial interest for Class A, Class B, Class C, Class N and Class Y,
respectively, valued at $4,460,569, $517,234, $453,714, $160,308 and $743 in
exchange for the net assets, resulting in combined Class A net assets of
$430,352,457, Class B net assets of $328,027,097, Class C net assets of
$102,832,057, Class N net assets of $15,671,309 and Class Y net assets of
$16,967,112 on September 4, 2003. The net assets acquired included net
unrealized appreciation of $858,837 and an unused capital loss carryforward of
$1,913,251, potential utilization subject to tax limitations. The exchange
qualified as a tax-free reorganization for federal income tax purposes.


- --------------------------------------------------------------------------------
8. Borrowing and Lending Arrangements
The Fund entered into an "interfund borrowing and lending arrangement" with
other funds in the Oppenheimer funds complex, to allow funds to borrow for
liquidity purposes. The arrangement was initiated pursuant to exemptive relief
granted by the Securities and Exchange Commission to allow these affiliated
funds to lend money to, and borrow money from, each other, in an attempt to
reduce borrowing costs below those of bank loan facilities. Under the
arrangement the Fund may lend money to other Oppenheimer funds and may borrow
from other Oppenheimer funds at a rate set by the Fund's Board of Trustees,
based upon a recommendation by the Manager. The Fund's borrowings, if any, are
subject to asset coverage requirements under the Investment Company Act and the
provisions of the SEC order and other applicable regulations. If the Fund
borrows money, there is a risk that the loan could be called on one day's
notice, in which case the Fund might have to borrow from a bank at higher rates
if a loan were not available from another Oppenheimer fund. If the Fund lends
money to another fund, it will be subject to the risk that the other fund might
not repay the loan in a timely manner, or at all.
   The Fund had no interfund borrowings or loans outstanding during the year
ended or at October 31, 2003.

INDEPENDENT AUDITORS' REPORT
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
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, 2003, and the related statement of operations for the year then ended, the
statements of changes in net assets for each of the two years in the period then
ended, and the financial highlights for each of the four years in the period
then ended. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits. The financial highlights for the year ended October 31, 1999 were
audited by other auditors whose report dated November 19, 1999, expresses an
unqualified opinion on this information.

   We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. 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, 2003, 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, 2003, the results of its operations
for the year then ended, the changes in its net assets for each of the two years
in the period then ended, and the financial highlights for each of the four
years in the period then ended, in conformity with accounting principles
generally accepted in the United States of America.

In early 2004, if applicable, shareholders of record will receive information
regarding all dividends and distributions paid to them by the Fund during
calendar year 2003. Regulations of the U.S. Treasury Department require the Fund
to report this information to the Internal Revenue Service.
   A portion, if any, of the dividends paid by the Fund during the fiscal year

are eligible for lower individual income tax rates to the extent that the Fund
has received qualified dividend income as stipulated by recent tax legislation.
$1,371,241 of the Fund's fiscal year taxable income may be eligible for the
lower individual income tax rates. In early 2004, shareholders of record will
receive information regarding the percentage of distributions that are eligible
for lower individual income tax rates.
   The foregoing information is presented to assist shareholders in reporting
distributions received from the Fund to the Internal Revenue Service. Because of

ITEM 2.  CODE OF ETHICS

ITEM 3.  AUDIT COMMITTEE FINANCIAL EXPERT

The Board of Trustees of the Fund has determined that the Fund 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.

         Act of 1940 (17 CFR 270.30a-2(c)) as of October 31, 2003, registrant's
         principal executive officer and principal financial officer found
         registrant's disclosure controls and procedures to be appropriately
         designed to ensure 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.

          (b) There have been no significant changes in registrant's internal
         controls or in other factors that could significantly affect
         registrant's internal controls subsequent to the date of the most
         recent evaluation as indicated, including no significant deficiencies
         or material weaknesses that required corrective action.
