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 11/1/00. Unless
otherwise noted, Class A returns include the current maximum initial sales
charge of 5.75%.

CLASS B shares of the Fund were first publicly offered on 11/1/00. 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 "since inception" 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 11/1/00. Unless
otherwise noted, Class C returns include the contingent deferred sales charge of
1% for the 1-year period. Class C shares are subject to an annual 0.75%
asset-based sales charge.

CLASS N shares of the Fund were first publicly offered on 3/1/01. Class N shares
are offered only through retirement plans. Unless otherwise noted, Class N
returns include the contingent deferred sales charge of 1% for the 1-year
period. Class N shares are subject to an annual 0.25% asset-based sales charge.


                      12 | OPPENHEIMER EMERGING GROWTH FUND



CLASS Y shares of the Fund were first publicly offered on 11/1/00. 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 EMERGING GROWTH 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 April 30, 2007.

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 exceptions
described in the Statement of Additional Information). Therefore,


                      14 | OPPENHEIMER EMERGING GROWTH FUND



the "hypothetical" lines of the table are useful in comparing ongoing costs
only, and will not help you determine the relative total costs of owning
different funds. In addition, if these transactional costs were included, your
costs would have been higher.

Class Y Hypothetical                1,000.00      1,020.13       4.72

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 181/365
(to reflect the one-half year period). Those annualized expense ratios,
excluding indirect expenses from affiliated fund, based on the 6-month period
ended April 30, 2007 are as follows:

CLASS          EXPENSE RATIOS
- -----------------------------
Class A             1.59%
- -----------------------------
Class B             2.40
- -----------------------------
Class C             2.38
- -----------------------------
Class N             1.84
- -----------------------------
Class Y             0.94

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 Emerging Growth Fund (the Fund) is an open-end management investment
company registered under the Investment Company Act of 1940, as amended. 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(R) are valued based on the
closing price provided by NASDAQ prior to the time when the Fund's assets are
valued. In the absence of a sale, the security is valued at the last sale price
on the prior trading day, if it is within the spread of the closing "bid" and
"asked" prices, and if not, at the closing bid price. Securities traded on
foreign exchanges are valued based on the last sale price on the principal
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
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


                      30 | OPPENHEIMER EMERGING GROWTH FUND



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. Options are
valued daily based upon the last sale price on the principal exchange on which
the option is traded. Securities (including restricted securities) for which
market quotations are not readily available are valued at their fair value.
Foreign and domestic securities whose values have been materially affected by
what the Manager identifies as a significant event occurring before the Fund's
assets are valued but after the close of their respective exchanges will be fair
valued. Fair value is determined in good faith using consistently applied
procedures under the supervision of the Board of Trustees. Investments in
open-end registered investment companies (including affiliated funds) are valued
at that fund's net asset value. Short-term "money market type" debt securities
with remaining maturities of sixty days or less are valued at amortized cost
(which approximates market value).

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

- --------------------------------------------------------------------------------
INVESTMENT IN OPPENHEIMER INSTITUTIONAL MONEY MARKET FUND. The Fund is permitted
to invest daily available cash balances in an affiliated money market fund. The
Fund may invest the available cash in Class E shares of Oppenheimer
Institutional Money Market Fund ("IMMF") which seeks current income and
stability of principal. IMMF is a registered open-end management investment
company, regulated as a money market fund under the Investment Company Act of
1940, as amended. The Manager is also the investment advisor of IMMF. The Fund's
investment in IMMF is included in the Statement of Investments. As a
shareholder, the Fund is subject to its proportional share of IMMF's


                      31 | OPPENHEIMER EMERGING GROWTH FUND



NOTES TO FINANCIAL STATEMENTS  Unaudited / Continued
- --------------------------------------------------------------------------------

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

Class E expenses, including its management fee. The Manager will waive fees
and/or reimburse Fund expenses in an amount equal to the indirect management
fees incurred through the Fund's investment in IMMF.

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

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

      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.

      During the fiscal year ended October 31, 2006, the Fund utilized $217,219
of capital loss carryforward to offset capital gains realized in that fiscal
year.

- --------------------------------------------------------------------------------
TRUSTEES' COMPENSATION. The Fund has adopted an unfunded retirement plan (the
"Plan") for the Fund's independent trustees. Benefits are based on years of
service and fees paid to each trustee during their period of service. The Plan
was frozen with respect to adding new participants effective December 31, 2006
(the "Freeze Date") and existing Plan Participants as of the Freeze Date will
continue to receive accrued benefits under the Plan. Active independent trustees
as of the Freeze Date have each elected a distribution method with respect to
their benefits under the Plan. During the six months ended April 30, 2007, the
Fund's projected benefit obligations were increased by $4,635 and payments of
$2,364 were made to retired trustees, resulting in an accumulated liability of
$11,023 as of April 30, 2007.

      The Board of Trustees has adopted a compensation deferral plan for
independent trustees that enables trustees to elect to defer receipt of all or a
portion of the annual compensation they are entitled to receive from the Fund.
For purposes of determining the amount owed to the Trustee under the plan,
deferred amounts are treated as though equal dollar amounts had been invested in
shares of the Fund or in other Oppenheimer funds selected by the Trustee. The
Fund purchases shares of the funds selected for 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


                      32 | OPPENHEIMER EMERGING GROWTH FUND



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 compensation deferral 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. Such interest expense and other custodian fees may be paid
with these earnings.

- --------------------------------------------------------------------------------
SECURITY TRANSACTIONS. Security transactions are recorded on the trade date.
Realized gains and losses on securities sold are determined on the basis of
identified cost.

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

                      Over $600 million           0.75

- --------------------------------------------------------------------------------
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 April 30, 2007, the Fund paid
$197,922 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

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 determines its uncompensated expenses under the
plan at calendar quarter ends. The Distributor's aggregate uncompensated
expenses under the plan at March 31, 2007 for Class B, Class C and Class N
shares were $16,862, $282,182 and $83,541, respectively. Fees incurred by the
Fund under the plans are detailed in the Statement of Operations.

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

WAIVERS AND REIMBURSEMENTS OF EXPENSES. 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 April 30, 2007,
OFS waived $8,289, $11,370, $9,506 and $5,897 for Class A, Class B, Class C and
Class N shares, respectively. This undertaking may be amended or withdrawn at
any time.

      The Manager will waive fees and/or reimburse Fund expenses in an amount
equal to the indirect management fees incurred through the Fund's investment in
IMMF. During the six months ended April 30, 2007, the Manager waived $899 for
IMMF management fees.

- --------------------------------------------------------------------------------
5. FOREIGN CURRENCY CONTRACTS

A foreign currency contract is a commitment to purchase or sell a foreign
currency at a future date, at a negotiated rate. The Fund may enter into foreign
currency contracts to settle specific purchases or sales of securities
denominated in a foreign currency and for protection from adverse exchange rate
fluctuation. Risks to the Fund include the potential inability of the
counterparty to meet the terms of the contract.


                      36 | OPPENHEIMER EMERGING GROWTH FUND



      The net U.S. dollar value of foreign currency underlying all contractual
commitments held by the Fund and the resulting unrealized appreciation or
depreciation are determined using prevailing foreign currency exchange rates.
Unrealized appreciation and depreciation on foreign currency contracts are
reported in the Statement of Assets and Liabilities as a receivable or payable
and in the Statement of Operations with the change in unrealized appreciation or
depreciation.

      The Fund may realize a gain or loss upon the closing or settlement of the
foreign transaction. Contracts closed or settled with the same broker are
recorded as net realized gains or losses. Such realized gains and losses are
reported with all other foreign currency gains and losses in the Statement of
Operations.

      As of April 30, 2007, the Fund had no outstanding foreign currency
contracts.

- --------------------------------------------------------------------------------
6. RECENT ACCOUNTING PRONOUNCEMENTS

In June 2006, the Financial Accounting Standards Board ("FASB") issued FASB
Interpretation No. 48 ("FIN 48"), ACCOUNTING FOR UNCERTAINTY IN INCOME TAXES.
FIN 48 clarifies the accounting for uncertainty in income taxes recognized in an
enterprise's financial statements in accordance with FASB Statement No. 109,
ACCOUNTING FOR INCOME TAXES. FIN 48 requires the evaluation of tax positions
taken in the course of preparing the Fund's tax returns to determine whether it
is "more-likely-than-not" that tax positions taken in the Fund's tax return will
be ultimately sustained. A tax liability and expense must be recorded in respect
of any tax position that, in Management's judgment, will not be fully realized.
FIN 48 is effective for fiscal years beginning after December 15, 2006. As of
April 30, 2007, the Manager has evaluated the implications of FIN 48 and does
not currently anticipate a material impact to the Fund's financial statements.
The Manager will continue to monitor the Fund's tax positions prospectively for
potential future impacts.

      In September 2006, the FASB issued Statement of Financial Accounting
Standards ("SFAS") No. 157, FAIR VALUE MEASUREMENTS. This standard establishes a
single authoritative definition of fair value, sets out a framework for
measuring fair value and expands disclosures about fair value measurements. SFAS
No. 157 applies to fair value measurements already required or permitted by
existing standards. SFAS No. 157 is effective for financial statements issued
for fiscal years beginning after November 15, 2007, and interim periods within
those fiscal years. As of April 30, 2007, the Manager does not believe the
adoption of SFAS No. 157 will materially impact the financial statement amounts;
however, additional disclosures may be required about the inputs used to develop
the measurements and the effect of certain of the measurements on changes in net
assets for the period.

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 about the
nature and extent of the services provided to the Fund and information regarding
the Manager's key personnel who 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
all administrative and clerical personnel who 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.

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

      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 account of the fact 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 Robert
Corbett and the Manager's Growth investment team and analysts. The Board members
also considered their experiences with the Manager and its officers and other
personnel through their service on the boards 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 its members have become
knowledgeable about 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 and from 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 investment 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 retail front-end load and no-load
small-cap growth funds advised by the Manager and by other investment advisers.
The Board noted that the Fund's three-year and five-year performance were below
its peer group median. However its one-year performance was better than its peer
group median.

      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 the fees and services for 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 are lower than
its peer median.


                      40 | OPPENHEIMER EMERGING GROWTH FUND



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

      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 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 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.


ITEM 11. CONTROLS AND PROCEDURES.






Based on their evaluation of the registrant's disclosure controls and procedures
(as defined in rule 30a-3(c) under the Investment Company Act of 1940 (17 CFR
270.30a-3(c)) as of 04/30/2007, the registrant's principal executive officer and
principal financial officer found the registrant's disclosure controls and
procedures to provide reasonable assurances that information required to be
disclosed by the registrant in the reports that it files under the Securities
Exchange Act of 1934 (a) is accumulated and communicated to registrant's
management, including its principal executive officer and principal financial
officer, to allow timely decisions regarding required disclosure, and (b) is
recorded, processed, summarized and reported, within the time periods specified
in the rules and forms adopted by the U.S. Securities and Exchange Commission.

There have been no changes in the registrant's internal controls over financial
reporting that occurred during the registrant's second fiscal quarter of the
period covered by this report that have materially affected, or are reasonably
likely to materially affect, the registrant's internal control over financial
reporting.
