LETTER TO SHAREHOLDERS

Dear Shareholder,


It is nearly impossible to reflect on the past six months without thinking about
the war with Iraq. We experienced a range of emotions in the days leading up to
the war and especially as the media brought the war into our homes, as never
before.
   At OppenheimerFunds, we face the difficult task of looking beyond the war to
see its long-term impact, together with other factors, on the global economy,
the financial markets and, in the end, your investment with us. It's a
responsibility that we take very seriously and becomes our primary focus during
uncertain times like these.
   It is our strong belief that investors can be well served by this
professional insight and by the guidance provided by a financial advisor. In
partnership with OppenheimerFunds, your financial advisor can help you navigate
through this volatile and sometimes unpredictable environment. We encourage you
to continue to work closely with your advisor to develop and implement an
investment plan that fits your goals and risk tolerance.
   On our end, we continue to be the home to some of the most experienced and
talented investment professionals in the industry. They remain focused on proven
methods that drive informed, intelligent investment decisions. It is an approach
we are proud of and one that has served investors well in a variety of market
conditions.
   We've found that in good times and bad, the fundamental principles of
investing remain key for financial success. These principles-- investing
according to your goals, diversifying your portfolio and benefiting from the
value of professional investment advice--are simple ideas that have proven
themselves over time, and, we believe, will prove themselves again.
   We thank you for your continued confidence in OppenheimerFunds and encourage
you to visit our website, www.oppenheimerfunds.com, or speak with your advisor
for up to date information on your investments and the markets.

Sincerely,

/S/ SIGNATURE

AN INTERVIEW WITH YOUR FUND'S MANAGER

Q

How would you characterize the Fund's performance during the six-month period
that ended April 30, 2003?

A. The Fund delivered slightly below average performance during a difficult
period. 1 Returns were undermined by high levels of market volatility generated
by unpredictable geopolitical events and a shaky transition from recession to
gradual growth. We believe these results generally reflect short-term market
fluctuations rather than the broader trends responsible for the Fund's
longer-term performance. We believe our long-term record of performance
demonstrates the enduring value of our disciplined approach to growth investing,
which focuses on a company's ability to sustain true internal revenue growth.

What made this such a challenging period for stocks?
Conflicting economic and political forces battered markets during the past six
months. On the positive side, the U.S. economy showed signs of modest growth,
while interest rates remained low and inflation remained in check. On the
negative side, corporate capital spending remained weak, consumer sentiment
declined and geopolitical uncertainties sapped investor confidence. These
conditions created high levels of volatility, with stock prices rising and
falling in response to international political developments as well as
company-specific business results.

   The market's volatility was also reflected in abrupt shifts in sentiment with
regard to various industries and sectors. For example, technology and health
care stocks tended to move in opposite directions at any one moment, depending
on whether the news of the day encouraged growth investors to hold a more
strongly positive or negative economic outlook. As optimism rose, investors
shifted assets into technology stocks they believed were more likely to benefit
from economic gains. As prospects for growth dimmed, growth investors sought
shelter

in the traditionally defensive health care area. These shifts drove individual
stock prices sharply higher and lower, often without any reference to a
company's underlying fundamentals.

How did you manage the Fund under these conditions? We focused on stocks of
companies with strong earnings growth generated by increasing sales. We believe
that sales-driven earnings growth is intrinsically more sustainable than growth
that is driven primarily by acquisitions or accounting gimmicks. Among stocks
that met our investment criteria, we emphasized those we believed could maintain
revenue growth during this difficult economic period. By focusing on the quality
rather than the magnitude of a company's growth, we cushioned the impact of
market volatility on the Fund, while avoiding many of the market's sharpest
losses. We also maintained the Fund's concentration on mid-cap stocks. Mid-cap
companies generally provide greater growth potential than larger companies and
lower risks of failure than smaller companies, thereby offering the best of both
worlds.

   Our company-by-company stock selection approach led us to concentrate a
relatively high percentage of assets in the areas of health care, consumer and
technology, each of which resulted in positive contributions to the Fund's
relative performance in the last six months. Health care proved to be the Fund's
largest single area of investment, because that's where we found the largest
number of companies generating the kind of sustainable, internal revenue growth
we target. Key holdings included equipment suppliers, such as Varian Medical
Systems, Inc., and biotechnology companies, such as Gilead Sciences, Inc. While
we sold some positions in drug distribution companies that experienced a
slowdown in revenue growth, we added to other positions, such as Biomet, Inc.,
that were generating above-average, sales-driven earnings growth. In the
consumer area, we succeeded in identifying several strong-performers despite
weakness in consumer sentiment and seasonally

AN INTERVIEW WITH YOUR FUND'S MANAGER

disappointing sales experienced by many leading companies. Above-average
holdings ranged from natural foods retailers, such as Whole Foods Market, Inc.,
to upscale apparel and accessories companies, such as Coach, Inc. Among
technology stocks, we emphasized companies that stand at a favorable point in
their product cycle, such as wireless equipment manufacturers (e.g., UTStarcom,
Inc.), semiconductor makers (Marvell Technology Group Ltd.), and software
security developers (Symantec Corp.).

   On the other hand, the Fund sustained steeper-than-average losses in the
areas of industrials and financials. Both of these areas were adversely affected
by the market volatility and sector rotation trends mentioned earlier, as well
as weakening fundamentals among some of the Fund's individual holdings. We
responded by reducing the Fund's exposure to companies that showed disappointing
levels of growth.

What is your outlook for the future?
While short-term growth prospects are likely to face continuing geopolitical and
economic pressures, longer-term prospects appear favorable. Many of the
inventory excesses that inhibited technology growth in the past two years have
run their course, while low interest rates are likely to encourage companies to
reinvest in their business infrastructure. On the health care front, positive
regulatory developments have opened the door to new drug approvals.

   As always, we remain sharply focused on the underlying fundamentals that we
believe are the most reliable indicators of a company's long-term growth
prospects. Our disciplined strategy of building the portfolio one company and
one investment at a time has earned Oppenheimer MidCap Fund its exceptional
record of performance, and makes the Fund a continuing part of The Right Way to
Invest.

NOTES TO FINANCIAL STATEMENTS  Unaudited

- --------------------------------------------------------------------------------
 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. 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 under consistently applied procedures
 under the supervision of the Board of Trustees. Short-term "money market type"
 debt securities with remaining maturities of sixty days or less are valued at
 amortized cost (which approximates market value).

- --------------------------------------------------------------------------------
 Joint Repurchase Agreements. The Fund, along with other affiliated funds of the
 Manager, may transfer uninvested cash balances into one or more joint
 repurchase agreement accounts. These balances are invested in one or more
 repurchase agreements, secured by U.S. government securities. 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;
 however, in the event of default by the other party to the agreement, retention
 of the collateral may be subject to legal proceedings.

18  |  OPPENHEIMER MIDCAP FUND

- --------------------------------------------------------------------------------
 Allocation of Income, Expenses, Gains and Losses. Income, expenses (other than
 those attributable to a specific class), gains and losses are allocated daily
 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 continue to comply with provisions of the
 Internal Revenue Code applicable to regulated investment companies and to
 distribute all of its 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.
    As of April 30, 2003, the Fund had available for federal income tax purposes
 an estimated unused capital loss carryforward of $1,236,791,274. This estimated
 capital loss carryforward represents the carryforward as of the end of the last
 fiscal year, increased for losses deferred under tax accounting rules for 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. During the six
 months ended April 30, 2003, the Fund did not use carryforward to offset
 capital gains realized. During the year ended October 31, 2002, the Fund did
 not use carryforward to offset capital gains realized.

 As of October 31, 2002, the Fund had available for federal income tax purposes
 unused capital loss carryforwards as follows:

                                      ==============

- --------------------------------------------------------------------------------
 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, 2003, the Fund's projected benefit obligations were decreased
 by $4,304 and payments of $3,871 were made to retired trustees, resulting in an
 accumulated liability of $139,896 as of April 30, 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, the compensation deferred is invested by the Fund in the
 fund(s) 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.

NOTES TO FINANCIAL STATEMENTS  Unaudited / 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.

- --------------------------------------------------------------------------------
 Classification of Dividends and Distributions to Shareholders. 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.
    No distributions were paid during the six months ended April 30, 2003 and
 the year ended October 31, 2002.

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

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


- --------------------------------------------------------------------------------
 2. Shares of Beneficial Interest

 beneficial interest of each class. Transactions in shares of beneficial

 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.

 Written option activity for the six months ended April 30, 2003 was as follows:

                                                          Call Options

 6. Illiquid or Restricted Securities
 As of April 30, 2003, investments in securities included issues that are
 illiquid or restricted. Restricted securities are often 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 April 30, 2003 was
 $543,874, which represents 0.08% of the Fund's net assets, all of which is
 considered restricted. Information concerning restricted securities is as
 follows:

 7. Borrowing and Lending Arrangements
 Bank Borrowings. The Fund had the ability to borrow from banks for temporary or
 emergency purposes. Asset coverage for borrowings must be at least 300%. The
 Fund and other Oppenheimer funds participated in a $400 million unsecured line
 of credit from a bank, for liquidity purposes. Under that line of credit, each
 fund was charged interest on its borrowings at a rate equal to the Federal
 Funds rate plus 0.45%. The Fund paid a commitment fee on its pro rata share of
 the average unutilized amount of the credit facility at a rate of 0.08% per
 annum. The credit facility was terminated on November 12, 2002, when the Fund
 entered into the interfund borrowing and lending arrangements described below.
    The Fund had no outstanding borrowings under the credit facility through
 November 12, 2002.

24  |  OPPENHEIMER MIDCAP FUND

- --------------------------------------------------------------------------------
 Interfund Borrowing and Lending Arrangements. Commencing November 12, 2002, 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 investment 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 six
 months ended or at April 30, 2003.

PRIVACY POLICY NOTICE

As an Oppenheimer fund shareholder, you are entitled to know how we protect your
personal information and how we limit its disclosure.

Information Sources

 We obtain nonpublic personal information about our shareholders from the
 following sources:
o Applications or other forms
o When you create a user ID and password for online account access
o When you enroll in eDocs Direct, our electronic document delivery service
o Your transactions with us, our  affiliates or others
o A software program on our website, often referred to as a "cookie," which
  indicates which parts of our site you've visited

If you visit www.oppenheimerfunds.com and do not log on to the secure account
information areas, we do not obtain any personal information about you. When you
do log on to a secure area, we do obtain your user ID and password to identify
you.

We also use this information to provide you with products and services you have
requested, to inform you about products and services that you may be interested
in and to assist you in other ways.

Protection of Information
We do not disclose any nonpublic personal information (such as names on a
customer list) about current or former customers to anyone, except as permitted
by law.

Disclosure of Information
We send your financial advisor (as designated by you) copies of confirmations,
account statements and other documents reporting activity in your fund accounts.
We may also use details about you and your investments to help us, our financial
service affiliates or firms that jointly market their financial products and
services with ours, to better serve your investment needs or suggest financial
services or educational material that may be of interest to you.

Right of Refusal
We will not disclose your personal information to unaffiliated third parties
(except as permitted by law), unless we first offer you a reasonable opportunity
to refuse or "opt out" of such disclosure.

Security
In the coming months, an Internet browser that supports 128-bit encryption will
be required to view the secure pages of www.oppenheimerfunds.com. These areas
include:
 o Account access
 o Create a user ID and profile
 o User profile
 o eDocs Direct, our electronic document delivery service

To find out if your Internet browser supports 128-bit encryption, or for
instructions on how to upgrade your browser, visit the Help section of
www.oppenheimerfunds.com.

Emails and Encryption
As a security measure, we do not include personal or account information in
nonsecure emails, and we advise you not to send such information to us in
nonsecure emails. Instead, you may take advantage of the secure features of our
website to encrypt your email correspondence. To do this, you will need to use
an Internet browser that supports 128-bit encryption. If you are not sure if
your Internet browser supports 128-bit encryption, or need instructions on how
to upgrade your browser, visit the Help section of www.oppenheimerfunds.com for
assistance.

o All transactions, including redemptions, exchanges and purchases are secured
  by Secure Socket Layers (SSL) and encryption. SSL is used to establish a
  secure connection between your PC and OppenheimerFunds' server. It transmits
  information in an encrypted and scrambled format.

o Encryption is achieved through an electronic scrambling technology that uses a
  "key" to code and then decode the data. Encryption acts like the cable
  converter box you may have on your television set. It scrambles data with
  secret code so that no one can make sense of it while it is being transmitted.
  When the data reaches its destination, the same software unscrambles the data.

o You can exit the secure area by either closing your browser, or for added
  security, you can use the Log Out of Account Area button before you close your
  browser.

Other Security Measures
We maintain physical, electronic and procedural safeguards to protect your
personal account information. Our employees and agents have access to that
information only so that they may offer you products or provide services to you,
for example, when responding to your account questions.

How You Can Help
You can also do your part to keep your account information private, and to
prevent unauthorized transactions. If you obtain a user ID and password for your
account, do not allow it to be used by anyone else. Also, take special
precautions when accessing your account on a computer used by others.

         Act of 1940 (17 CFR 270.30a-2(c)) as of April 30, 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.
