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.

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. For more complete information
about the Fund, including charges, expenses and risks, please refer to the
prospectus. To obtain a copy, call your financial advisor or call
OppenheimerFunds Distributor, Inc. at 1.800.CALL OPP (1.800.225.5677). Read the
prospectus carefully before you invest or send money.

Class A shares of the Fund were first publicly offered on 4/27/01. Unless
otherwise noted, Class A returns include the current maximum initial sales
charge of 5.75%. Class A shares were the only class offered during the reporting
period.

An explanation of the calculation of performance is in the Fund's Statement of
Additional Information.

NOTES TO FINANCIAL STATEMENTS  UNAUDITED

- --------------------------------------------------------------------------------
 1. Significant Accounting Policies
 Oppenheimer Concentrated Growth Fund (the Fund) is registered under the
 Investment Company Act of 1940, as amended, as a non-diversified, 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). As of April 30, 2003, the majority of Class A shares were owned
 by the Manager.
    The Fund offers Class A shares. Class A shares are sold at their offering
 price, which is normally net asset value plus a front-end sales charge.
    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.
- --------------------------------------------------------------------------------
 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 $2,868,795. 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 increased
 by $35 and payments of $5 were made to retired trustees, resulting in an
 accumulated liability of $34 as of April 30, 2003.


7  |  OPPENHEIMER CONCENTRATED GROWTH FUND


NOTES TO FINANCIAL STATEMENTS  Unaudited / Continued

- --------------------------------------------------------------------------------
 1. Significant Accounting Policies Continued
    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.
- --------------------------------------------------------------------------------
 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 primarily because of the recognition of certain foreign
 currency gains (losses) as ordinary income (loss) for 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
 The Fund has authorized an unlimited number of no par value shares of
 beneficial interest. Transactions in shares of beneficial interest were as

                       Shares           Amount       Shares              Amount

- --------------------------------------------------------------------------------
 4. Fees and Other Transactions with Affiliates
 Management Fees. Management fees paid to the Manager were in accordance with
 the investment advisory agreement with the Fund which provides for a fee at an
 annual rate of 0.75% of the first $200 million of average annual net assets of
 the Fund, 0.72% of the next $200 million, 0.69% of the next $200 million, and
 0.66% of net assets over $600 million.
- --------------------------------------------------------------------------------
 Transfer Agent Fees. OppenheimerFunds Services (OFS), a division of the
 Manager, acts as the transfer and shareholder servicing agent for the Fund. The
 Fund pays OFS a $19.75 per account fee.
    OFS has voluntarily agreed to limit transfer and shareholder servicing agent
 fees, up to an annual rate of 0.35% of average net assets of Class A shares.
 This undertaking may be amended or withdrawn at any time.
- --------------------------------------------------------------------------------
 Distribution and Service Plan (12b-1) Fees. Under its General Distributor's
 Agreement with the Manager, OppenheimerFunds Distributor, Inc. (the
 Distributor) acts as the Fund's principal underwriter in the continuous public
 offering of the Class A shares of the Fund.
- --------------------------------------------------------------------------------
 Service Plan for Class A Shares. The Fund has adopted a Service Plan for Class
 A shares. It reimburses the Distributor for a portion of its costs incurred for
 services provided to accounts that hold Class A shares. Reimbursement is made
 quarterly at an annual rate of up to 0.25% of the average annual net assets of
 Class A shares of the Fund. For the six months ended April 30, 2003, payments
 under the Class A plan totaled $5,662 prior to the voluntary waiver of all such
 current period fees by the Manager, all of which were paid by the Distributor
 to recipients, none of which was paid to an affiliate of the Manager. Any
 unreimbursed expenses the Distributor incurs with respect to Class A shares in
 any fiscal year cannot be recovered in subsequent years.

- --------------------------------------------------------------------------------
 5. Borrowing and Lending Arrangements
 Bank Borrowings. The Fund has 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.
- --------------------------------------------------------------------------------
 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.
- --------------------------------------------------------------------------------
 6. Subsequent Event
 The Fund will be liquidated in May, 2003.

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

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

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.

         principal executive officer and principal financial officer found

         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

         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.
