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

Total returns include changes in share price and reinvestment of dividends and
capital gains distributions in a hypothetical investment for the periods shown.
Cumulative total returns are not annualized. The Fund's total returns shown do
not reflect the deduction of income taxes on an individual's investment. Taxes
may reduce your actual investment returns on income or gains paid by the Fund or
any gains you may realize if you sell your shares. INVESTORS SHOULD CONSIDER THE
FUND'S INVESTMENT OBJECTIVES, RISKS, AND OTHER CHARGES AND EXPENSES CAREFULLY
BEFORE INVESTING. THE FUND'S PROSPECTUS CONTAINS THIS AND OTHER INFORMATION
ABOUT THE FUND, AND MAY BE OBTAINED BY ASKING YOUR FINANCIAL ADVISOR, CALLING US
AT 1.800.525.7048 OR VISITING OUR WEBSITE AT WWW.OPPENHEIMERFUNDS.COM. READ THE
PROSPECTUS CAREFULLY BEFORE INVESTING.

The Fund's investment strategy and focus can change over time. The mention of
specific fund holdings does not constitute a recommendation by OppenheimerFunds,
Inc.

CLASS A shares of the Fund were first publicly offered on 9/11/86. Unless
otherwise noted, Class A returns include the current maximum initial sales
charge of 5.75%. The Fund's maximum sales charge for Class A shares was lower
prior to 4/4/91, so actual performance may have been higher.

CLASS B shares of the Fund were first publicly offered on 4/4/94. Unless
otherwise noted, Class B returns include the applicable contingent deferred
sales charge of 5% (1-year) and 2% (5-year). Because Class B shares convert to
Class A shares 72 months after purchase, the 10-year return for Class B uses
Class A performance for the period after conversion. Class B shares are subject
to an annual 0.75% asset-based sales charge.

CLASS C shares of the Fund were first publicly offered on 10/2/95. 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.


                         12 | OPPENHEIMER DISCOVERY FUND



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.

CLASS Y shares of the Fund were first publicly offered on 6/1/94. Class Y shares
are offered only to certain institutional investors under special agreement with
the Distributor.

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


                         13 | OPPENHEIMER DISCOVERY FUND



FUND EXPENSES
- --------------------------------------------------------------------------------

FUND EXPENSES. As a shareholder of the Fund, you incur two types of costs:  1
transaction costs, which may include sales charges (loads) on purchase payments,
contingent deferred sales charges on redemptions; and redemption fees, if any;
and (2) ongoing costs, including management fees; distribution and service fees;
and other Fund expenses. These examples are intended to help you understand your
ongoing costs (in dollars) of investing in the Fund and to compare these costs
with the ongoing costs of investing in other mutual funds.

The examples are based on an investment of $1,000.00 invested at the beginning
of the period and held for the entire 6-month period ended March 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), redemption fees, or a $12.00 fee
imposed annually on accounts valued at less than $500.00 (subject to


                         14 | OPPENHEIMER DISCOVERY FUND



exceptions described in 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      1,019.90       5.10

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 182/365
(to reflect the one-half year period). Those annualized expense ratios based on
the 6-month period ended March 31, 2006 are as follows:

CLASS          EXPENSE RATIOS
- -----------------------------
Class A             1.26%
- -----------------------------
Class B             2.09
- -----------------------------
Class C             2.07
- -----------------------------
Class N             1.54
- -----------------------------
Class Y             1.01

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 Discovery 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 Fund assesses a 2% fee on the proceeds of
fund shares that are redeemed (either by selling or exchanging to another
Oppenheimer fund) within 30 days of their purchase. The fee, which is retained
by the Fund, is accounted for as an addition to paid-in capital.

      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 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 exchange 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


                         30 | OPPENHEIMER DISCOVERY FUND



will be valued at the mean between the "bid" and "asked" prices. Futures
contracts traded on a commodities or futures exchange will be valued at the
final settlement price or official closing price on the principal exchange as
reported by such principal exchange at its trading session ending at, or most
recently prior to, the time when the Fund's assets are valued. Securities
(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. 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. The values of securities denominated in foreign currencies and
amounts related to the purchase and sale of foreign securities and foreign
investment income are translated into U.S. dollars 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. Foreign exchange rates may be valued
primarily using dealer supplied valuations or a portfolio pricing service
authorized by the Board of Trustees.

      Reported net realized foreign exchange gains or losses arise from sales of
portfolio securities, sales and maturities of short-term securities, sales of
foreign currencies, currency gains or losses realized between the trade and
settlement dates on securities transactions, and the difference between the
amounts of dividends, interest, and foreign withholding taxes recorded on the
Fund's books and the U.S. dollar equivalent of the amounts actually received or
paid. Net unrealized foreign exchange gains and losses arise from changes in the
values of assets and liabilities, including investments in securities at fiscal
period end, resulting from changes in exchange rates.

      The effect of changes in foreign currency exchange rates on investments is
separately identified from the fluctuations arising from changes in market
values of securities held and reported with all other foreign currency gains and
losses in the Fund's Statement of Operations.

- --------------------------------------------------------------------------------
JOINT REPURCHASE AGREEMENTS. Pursuant to an Exemptive Order issued by the
Securities and Exchange Commission, the Fund, along with other affiliated funds
advised by the Manager, may transfer uninvested cash balances into joint trading
accounts on a daily basis. These balances are invested in one or more repurchase
agreements. Securities pledged as collateral for repurchase agreements are held
by a custodian bank until the agreements mature. Each agreement requires that
the market value of the collateral be sufficient to cover payments of interest
and principal. In the event of default by the other party to the agreement,
retention of the collateral may be subject to legal proceedings.

- --------------------------------------------------------------------------------
ALLOCATION OF INCOME, EXPENSES, GAINS AND LOSSES. Income, expenses (other than
those attributable to a specific class), gains and losses are allocated on a
daily basis to each class of shares based upon the relative proportion of net
assets represented by such class.

- --------------------------------------------------------------------------------
1. SIGNIFICANT ACCOUNTING POLICIES Continued

Operating expenses directly attributable to a specific class are charged against
the operations of that class.

- --------------------------------------------------------------------------------
FEDERAL TAXES. The Fund intends to comply with provisions of the Internal
Revenue Code applicable to regulated investment companies and to distribute
substantially all of its investment company taxable income, including any net
realized gain on investments not offset by capital loss carryforwards, if any,
to shareholders, therefore, no federal income or excise tax provision is
required.

      Net investment income (loss) and net realized gain (loss) may differ for
financial statement and tax purposes. The character of dividends and
distributions made during the fiscal year from net investment income or net
realized gains may differ from their ultimate characterization for federal
income tax purposes. Also, due to timing of dividends and distributions, the
fiscal year in which amounts are distributed may differ from the fiscal year in
which the income or net realized gain was recorded by the Fund.

      As of March 31, 2006, the Fund had available for federal income tax
purposes an estimated capital loss carryforward of $97,328,995. This estimated
capital loss carryforward represents carryforward as of the end of the last
fiscal year, increased for losses deferred under tax accounting rules to the
current fiscal year and is increased or decreased by capital losses or gains
realized in the first six months of the current fiscal year. As of March 31,
2006, it is estimated that the Fund will utilize $52,314,508 of capital loss
carry-forward to offset realized capital gains. During the year ended September
30, 2005, the Fund utilized $84,188,783 of capital loss carryforward to offset
capital gains realized in that fiscal year.

As of September 30, 2005, 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
March 31, 2006, the Fund's projected benefit obligations were decreased by
$14,892 and payments of $15,887 were made to retired trustees, resulting in an
accumulated liability of $161,602 as of March 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


                         32 | OPPENHEIMER DISCOVERY FUND



selected for deferral by the Trustee in amounts equal to his or her deemed
investment, resulting in a Fund asset equal to the deferred compensation
liability. Such assets are included as a component of "Other" within the asset
section of the Statement of Assets and Liabilities. Deferral of trustees' fees
under the plan will not affect the net assets of the Fund, and will not
materially affect the Fund's assets, liabilities or net investment income per
share. Amounts will be deferred until distributed in accordance to the Plan.

- --------------------------------------------------------------------------------
DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions to
shareholders, which are determined in accordance with income tax regulations,
are recorded on the ex-dividend date. Income and capital gain distributions, if
any, are declared and paid annually.

- --------------------------------------------------------------------------------
INVESTMENT INCOME. Dividend income is recorded on the ex-dividend date or upon
ex-dividend notification in the case of certain foreign dividends where the
ex-dividend date may have passed. Non-cash dividends included in dividend
income, if any, are recorded at the fair market value of the securities
received. Interest income, which includes accretion of discount and amortization
of premium, is accrued as earned.

- --------------------------------------------------------------------------------
CUSTODIAN FEES. "Custodian fees and expenses" in the Statement of Operations may
include interest expense incurred by the Fund on any cash overdrafts of its
custodian account during the period. Such cash overdrafts may result from the
effects of failed trades in portfolio securities and from cash outflows
resulting from unanticipated shareholder redemption activity. The Fund pays
interest to its custodian on such cash overdrafts, 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. At March 31, 2006, the Fund had $16,834 of such earnings on
cash balances available to offset future custodian fees or interest expenses
incurred during the next fiscal year.

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

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

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,
0.72% of the next $200 million, 0.69% of the next $200 million, 0.66% of the
next $200 million, 0.60% of the next $700 million, and 0.58% of average annual
net assets in excess of $1.5 billion.

- --------------------------------------------------------------------------------
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 per account fee. For the six months ended March 31, 2006, the Fund paid
$1,335,586 to OFS for services to the Fund.

      Additionally, Class Y shares are subject to minimum fees of $10,000 per
annum for assets of $10 million or more. The Class Y shares are subject to the
minimum fees in the event that the per account fee does not equal or exceed the
applicable minimum fees. OFS may voluntarily waive the minimum fees.

- --------------------------------------------------------------------------------
DISTRIBUTION AND SERVICE PLAN (12b-1) FEES. Under its General Distributor's
Agreement with the Fund, OppenheimerFunds Distributor, Inc. (the Distributor)
acts as the Fund's principal underwriter in the continuous public offering of
the Fund's classes of shares.

- --------------------------------------------------------------------------------
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
periodically at an annual rate of up to 0.25% of the average annual net assets
of Class A shares of the Fund. The Distributor currently uses all of those fees
to pay dealers, brokers, banks and other financial institutions periodically for
providing personal services and maintenance of accounts of their customers that
hold Class A shares. Any unreimbursed expenses the Distributor incurs with
respect to Class A shares in any fiscal year cannot be recovered in subsequent
periods. Fees incurred by the Fund under the plan are detailed in the Statement
of Operations.

- --------------------------------------------------------------------------------
DISTRIBUTION AND SERVICE PLANS FOR CLASS B, CLASS C AND CLASS N SHARES. The Fund
has adopted Distribution and Service Plans for Class B, Class C and Class N
shares to compensate the Distributor for its services in connection with the
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 0.25% per year under each plan. If either the Class B, Class C or
Class N plan is terminated by the Fund or by the shareholders of a class, the
Board of Trustees and its independent trustees must determine whether the
Distributor shall be entitled to payment from the Fund of all or a portion of
the service fee and/or asset-based sales charge in respect to shares sold prior
to the effective date of such termination. The Distributor's aggregate
uncompensated expenses under the plan at March 31, 2006 for Class B, Class C and
Class N shares were $4,248,710, $1,339,438 and $134,445, respectively. Fees
incurred by the Fund under the plans are detailed in the Statement of
Operations.

WAIVERS AND REIMBURSEMENTS OF EXPENSES. Effective January 1, 2005, the Manager
has voluntarily agreed to reduce its advisory fee rate for any quarter during
the calendar year ending December 31, 2005, by 0.05% of the Fund's average daily
net assets if the Fund's trailing one-year total return performance, measured at
the end of the prior calendar quarter, was in the fourth or fifth quintile of
the Fund's Lipper peer group if the Fund's performance was in the third quintile
or higher for a calendar quarter. However, the advisory fee reduction would be
terminated for the remainder of the calendar year. During the six months ended
March 31, 2006, the Manager waived $104,389 of its fees. The advisory fee
reduction is a voluntary undertaking and may be terminated by the Manager at any
time.

      OFS has voluntarily agreed to limit transfer and shareholder servicing
agent fees for all classes to 0.35% of average annual net assets per class.
During the six months ended March 31, 2006, OFS waived $7,918, $22,540, $14,047,
$3,344 and $8,620 for Class A, Class B, Class C, Class N and Class Y shares,
respectively. This undertaking may be amended or withdrawn at any time.

- --------------------------------------------------------------------------------
5. ILLIQUID OR RESTRICTED SECURITIES

As of March 31, 2006, investments in securities included issues that are
illiquid or restricted. Restricted securities are purchased in private placement
transactions, are not registered under the Securities Act of 1933, may have
contractual restrictions on resale, and are valued under methods approved by the
Board of Trustees as reflecting fair value. A security may also be considered
illiquid if it lacks a readily available market or if its valuation has not
changed for a certain period of time. The Fund will not invest more than 10% of
its net assets (determined at the time of purchase and reviewed periodically) in
illiquid or restricted securities. Certain restricted securities, eligible for
resale to qualified institutional investors, are not subject to that limitation.
Securities that are illiquid or restricted are marked with the applicable
footnote on the Statement of Investments. Information concerning restricted
securities is as follows:

6. LITIGATION

A complaint was filed as a putative class action against the Manager and the
Transfer Agent (and other defendants) 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.

      The Manager believes that it is premature to render any opinion as to the
likelihood of an outcome unfavorable to them, 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. However, the Manager believes that the allegations
contained in the complaints are without merit and that there are substantial
grounds to sustain the district court's rulings.

BOARD APPROVAL OF THE FUND'S INVESTMENT
ADVISORY AGREEMENT  Unaudited
- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------
Each year, the Board of Trustees (the "Board"), including a majority of the
independent Trustees, is required to determine whether to renew the Fund's
investment advisory agreement (the "Agreement"). The Investment Company Act of
1940, as amended, requires that the Board request and evaluate, and that the
Manager provide, such information as may be reasonably necessary to evaluate the
terms of the Agreement. The Board employs an independent consultant to prepare a
report that provides information, including comparative information that the
Board requests for that purpose. In addition, the Board receives information
throughout the year regarding Fund services, fees, expenses and performance.

      The Manager and the independent consultant provided information to the
Board on the following factors: (i) the nature, quality and extent of the
Manager's services, (ii) the investment performance of the Fund and the Manager,
(iii) the fees and expenses of the Fund, including comparative expense
information, (iv) the profitability of the Manager and its affiliates, including
an analysis of the cost of providing services by the Manager and its affiliates,
(v) the extent to which economies of scale are realized as the Fund grows and
whether fee levels reflect these economies of scale for Fund investors and (vi)
other benefits to the Manager from its relationship with the Fund. The Board was
aware that there are alternatives to retaining the Manager.

      NATURE AND EXTENT OF SERVICES. The Board considered information on the
nature and extent of the services provided to the Fund and information regarding
the Manager's key personnel that provide such services. The Manager's duties
include providing the Fund with the services of the portfolio manager and the
Manager's investment team, who provide research, analysis and other advisory
services in regard to the Fund's investments; securities trading services;
oversight of third party service providers; monitoring compliance with
applicable Fund policies and procedures and adherence to the Fund's investment
restrictions. The Manager is responsible for providing certain administrative
services to the Fund as well. Those services include providing, and supervising
the activities of, all administrative and clerical personnel that are necessary
in order to provide effective corporate administration for the Fund; compiling
and maintaining records with respect to the Fund's operations; preparing and
filing reports required by the Securities and Exchange Commission; preparing
periodic reports regarding the operations of the Fund for its shareholders;
preparing proxy materials for shareholder meetings; and preparing the
registration statements required by Federal and state securities laws for the
sale of the Fund's shares. The Manager also provides the Fund with office space,
facilities and equipment.

      QUALITY OF SERVICES. The Board also considered the quality of the services
provided and the quality of the Manager's resources that are available to the
Fund. The Board took

BOARD APPROVAL OF THE FUND'S INVESTMENT
ADVISORY AGREEMENT  Unaudited / Continued
- --------------------------------------------------------------------------------

account of the facts that the Manager has had over forty years of experience as
an investment adviser and that its assets under management rank it among the top
mutual fund managers in the United States. The Board evaluated the Manager's
administrative, accounting, legal and compliance services, and information the
Board has received regarding the experience and professional qualifications of
the Manager's personnel and the size and functions of its staff. In its
evaluation of the quality of the portfolio management services provided, the
Board considered the experience of Laura Granger and the Manager's Growth
investment team and analysts. Ms. Granger has had over 22 years of experience
managing equity investments. The Board members also considered their experiences
with the Manager and its officers and other personnel through their service as
directors or trustees of the Fund and other funds advised by the Manager. The
Board considered information regarding the quality of services provided by
affiliates of the Manager, which it also reviews at other times during the year
in connection with the renewal of the Fund's service agreements. In light of the
foregoing, the Board concluded that the Fund benefits from the services provided
under the Agreement as a result of the Manager's experience, reputation,
personnel, operations, and resources.

      INVESTMENT PERFORMANCE OF THE MANAGER AND THE FUND. During the year, the
Manager provided information on the performance of the Fund and the Manager at
each Board meeting, including comparative performance information. The Board
also reviewed information, prepared by the Manager and by the independent
consultant, comparing the Fund's historical performance to relevant market
indices and to the performance of other small-cap growth funds advised by the
Manager and other investment advisers. The Board noted that the Fund's one-year,
three-year, five-year and ten-year performance were below its peer group
average.

      MANAGEMENT FEES AND EXPENSES. The Board reviewed the fees paid to the
Manager and its affiliates and the other expenses borne by the Fund. The Board
also evaluated the comparability of the fees charged and the services provided
to the Fund to those of other clients or accounts advised by the Manager. The
independent consultant provided comparative data in regard to the fees and
expenses of the Fund, other small-cap growth funds and other funds with
comparable asset levels and distribution features. The Board noted that the
Fund's contractual and actual management fees and total expenses were all lower
than its peer group median and average.

      ECONOMIES OF SCALE. The Board reviewed the extent to which the Manager may
realize economies of scale in managing and supporting the Fund, to what extent
those economies of scale benefit the Fund shareholders and the current level of
Fund assets in relation to the Fund's breakpoint schedule for its management
fees. The Board also noted


                         40 | OPPENHEIMER DISCOVERY FUND



the Fund's breakpoints, which are intended to share economies of scale that may
exist as the Fund grows with its shareholders.

      PROFITS AND OTHER BENEFITS TO THE MANAGER. The Board considered
information regarding the Manager's costs in serving as the Fund's investment
adviser, including the costs associated with the personnel and systems necessary
to manage the Fund, and information regarding the Manager's profitability from
its relationship with the Fund. The Board considered that the Manager must be
able to pay and retain experienced professional personnel at competitive rates
to provide services to the Fund and that maintaining the financial viability of
the Manager is important in order for the Manager to continue to provide
significant services to the Fund and its shareholders. In addition to
considering the profits realized by the Manager, the Board considered
information regarding the direct and indirect benefits the Manager receives as a
result of its relationship with the Fund, including compensation paid to the
Manager's affiliates for services provided and research provided to the Manager
in connection with permissible brokerage arrangements (soft dollar
arrangements).

      CONCLUSIONS. These factors were also considered by the independent
Trustees meeting separately from the full Board, assisted by experienced counsel
to the Fund and the independent Trustees. Fund counsel is independent of the
Manager within the meaning and intent of the Securities and Exchange Commission
Rules.

      Based on its review of the information it received and its evaluations
described above, the Board, including a majority of the independent Trustees,
concluded that the nature, extent and quality of the services provided to the
Fund by the Manager are a benefit to the Fund and in the best interest of the
Fund's shareholders and that the amount and structure of the compensation
received by the Manager and its affiliates are reasonable in relation to the
services provided. Accordingly, the Board elected to continue the advisory
agreement for another year. In arriving at this decision, the Board did not
single out any factor or factors as being more important than others, but
considered all of the factors together. The Board judged the terms and
conditions of the advisory agreement, including the management fee, in light of
all of the surrounding circumstances.

THE FUND'S GOVERNANCE COMMITTEE PROVISIONS WITH RESPECT TO NOMINATIONS OF
DIRECTORS/TRUSTEES TO THE RESPECTIVE BOARDS

1.    The Fund's Governance 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.

likely to materially affect, the registrant's internal control over financial
