FUND PERFORMANCE DISCUSSION
- --------------------------------------------------------------------------------

HOW HAS THE FUND PERFORMED? BELOW IS A DISCUSSION BY OPPENHEIMERFUNDS, INC., OF
THE FUND'S PERFORMANCE DURING ITS FISCAL YEAR ENDED AUGUST 31, 2004, FOLLOWED BY
A GRAPHICAL COMPARISON OF THE FUND'S PERFORMANCE TO AN APPROPRIATE BROAD-BASED
MARKET INDEX.

MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE. Over the 12-month period ended
August 31, 2004, the Fund's performance trailed that of its benchmarks. Despite
relatively strong gains from several technology holdings, disappointing results
among individual stock selections in other sectors undermined returns.

      The Fund's investment strategy focuses on the market's higher growth
companies, regardless of their size. In particular, we target companies that we
believe are distinguished by proven management, innovative products or services,
strong earnings and revenue growth, and sustainable growth rates.

      During the reporting period, we found a relatively large number of
investment opportunities meeting these criteria in technology. Although the
technology sector proved to be one of the market's weakest performing areas
during the period, the Fund's technology holdings delivered slightly better
returns, albeit the performance was still negative. In fact, four of the Fund's
top six performers were technology stocks. These included software developers
Symantec Corp. and AutoDesk, Inc.; semiconductor maker Marvell Technology Group
Ltd.; and Internet service provider Yahoo!, Inc. Other technology holdings, such
as EMC Corp., declined along with the sector, but on average the Fund's gains in
technology surpassed its losses.

      Unfortunately, the Fund's individual stock selections in other sectors
proved less favorable. For example, among consumer discretionary holdings, the
strong performance of retailer Urban Outfitter, Inc. was undermined by
disappointing performance from various media and entertainment related holdings
including: Marvel Enterprises, Inc. and InterActiveCorp. Similarly, in the
health care area, the Fund's positive returns from its investment in
biotechnology company Genentech, Inc. were overbalanced by declines in other
biotechnology holdings, such as Gilead Sciences, Inc. Finally, among financial
stocks, the Fund's holding in mortgage guarantee provider Radian Group, Inc. was
hurt by a drop in refinancing activity resulting from an increase in interest
rates.

      As of the end of the period, we have trimmed the Fund's exposure to
technology, although the Fund continues to hold an overweighted position in that
sector. We have also reduced the Fund's consumer discretionary holdings,
primarily among media companies, an area the Fund has had a relatively light
exposure. We have increased the Fund's industrial exposure, focusing on
conglomerates, such as General Electric Co., a diversified company that has
recently moved to emphasize growth-oriented areas of its business, such as
entertainment and medical.

COMPARING THE FUND'S PERFORMANCE TO THE MARKET. The graphs that follow show the
performance of a hypothetical $10,000 investment in each class of shares of the
Fund held until August 31, 2004. In the case of Class A, Class B, and Class C
shares, performance is measured from the inception date of November 7, 1995; in
the case of Class N shares, from the inception of the Class on March 1, 2001,
and in the case of Class Y shares, from the inception of the Class on April 1,
1999. The Fund's performance reflects the deduction of the maximum initial sales
charge on Class A shares, the applicable contingent deferred sales charge on
Class B, Class C, and Class N shares, and reinvestments of all dividends and
capital gains distributions. Past performance cannot guarantee future results.

      The Fund has changed its secondary benchmark index from the Russell 2000
Index to the Russell 3000 Growth Index. The Fund believes that the Russell 3000
Growth Index, a multi-cap index, is a more appropriate benchmark reflecting the
types of multi-cap securities in which the Fund invests. The Fund will continue
to compare its performance to the Standard & Poor's (S&P) 500 Index.

      The Fund's performance is compared to the performance of the S&P 500
Index, the Russell 3000 Growth Index, and its previous secondary benchmark, the
Russell 2000 Index. The S&P 500 Index is a broad-based index of equity
securities widely regarded as a general measure of the performance of the U.S.
equity securities market. The Russell 3000 Growth index is a multi-cap index of
U.S. equity securities with greater-than-average growth orientation. The Russell
2000 Index is a capitalization-weighted index of 2,000 U.S. issuers whose common
stocks are traded on The New York and American Stock Exchanges and NASDAQ, and
is widely recognized as a measure of the performance of mid-capitalization
stocks. Index performance reflects the reinvestment of income but does not
consider the effect of transaction costs, and none of the data in the graphs
shows the effect of taxes. The Fund's performance reflects the effects of the
Fund's business and operating expenses. While index comparisons may be useful to
provide a benchmark for the Fund's performance, it must be noted that the Fund's
investments are not limited to the investments in the indices.

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

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.

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 11/7/95. Class A
returns include the current maximum initial sales charge of 5.75%.

CLASS B shares of the Fund were first publicly offered on 11/7/95. 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 11/7/95. 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.

CLASS Y shares of the Fund were first publicly offered on 4/1/99. Class Y shares
are offered only to certain institutional investors under special agreements
with the Distributor.

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


                        17 | OPPENHEIMER ENTERPRISE 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 August 31, 2004.

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), or a $12.00 fee imposed annually
on accounts valued at less than $500.00 (subject to exceptions described in


                         18 | OPPENHEIMER ENTERPRISE FUND


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.

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 184/366
(to reflect the one-half year period). Those expense ratios for the 6-month
period ended August 31, 2004 are as follows:

CLASS    EXPENSE RATIOS
- -----------------------
Class A      1.43%
- -----------------------
Class B      2.24
- -----------------------
Class C      2.18
- -----------------------
Class N      1.68
- -----------------------
Class Y      0.98

The expense ratios reflect voluntary reimbursements of expenses by the Fund's
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 reimbursements.

1. SIGNIFICANT ACCOUNTING POLICIES

Oppenheimer Enterprise 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 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 listed
or traded on National Stock Exchanges or other domestic or foreign exchanges are
valued based on the last sale price of the security traded on that exchange
prior to the time when the Fund's assets are valued. Securities traded on NASDAQ
are valued based on the closing price provided by NASDAQ prior to the time when
the Fund's assets are valued. In the absence of a sale, the security is valued
at the last sale price on the prior trading day, if it is within the spread of
the closing bid and asked prices, and if not, at the closing bid price.
Corporate, government and municipal debt instruments having a remaining maturity
in excess of 60 days and all mortgage-backed securities will be valued at the
mean between the "bid" and "asked" prices. Securities may be valued primarily
using dealer-supplied valuations or a portfolio pricing service authorized by
the Board of Trustees. 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


                        32 | OPPENHEIMER ENTERPRISE FUND



remaining maturities of sixty days or less are valued at amortized cost (which
approximates market value).

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

requirements the Fund must satisfy under the income tax regulations, losses the
Fund may be able to offset against income and gains realized in future years and
unrealized appreciation or depreciation of securities and other investments for
federal income tax purposes.

1. As of August 31, 2004, the Fund had $367,000,131 of net capital loss
carryforwards available to offset future realized capital gains, if any, and
thereby reduce future taxable gain distributions. As of August 31, 2004, details
of the capital loss carryforwards were as follows:

2. During the fiscal year ended August 31, 2004, the Fund utilized $16,574,046
of capital loss carryforward to offset capital gains realized in that fiscal
year.

3. During the fiscal year ended August 31, 2003, the Fund did not utilize any
capital loss carryforward.

Net investment income (loss) and net realized gain (loss) may differ for
financial statement and tax purposes. The character of dividends and
distributions made during the fiscal year from net investment income or net
realized gains may differ from their ultimate characterization for federal
income tax purposes. Also, due to timing of dividends and distributions, the
fiscal year in which amounts are distributed may differ from the fiscal year in
which the income or net realized gain was recorded by the Fund. Accordingly, the
following amounts have been reclassified for August 31, 2004. Net assets of the
Fund were unaffected by the reclassifications.

No distributions were paid during the years ended August 31, 2004 and August 31,
2003.

The aggregate cost of securities and other investments and the composition of
unrealized appreciation and depreciation of securities and other investments for
federal income tax purposes as of August 31, 2004 are noted below. The primary
difference between book and tax appreciation or depreciation of securities and
other investments,


                        34 | OPPENHEIMER ENTERPRISE FUND


if applicable, is attributable to the tax deferral of losses or tax realization

- --------------------------------------------------------------------------------
TRUSTEES' COMPENSATION. The Fund has adopted an unfunded retirement plan for the
Fund's independent trustees. Benefits are based on years of service and fees
paid to each trustee during the years of service. During the year ended August
31, 2004, the Fund's projected benefit obligations were increased by $4,119 and
payments of $4,391 were made to retired trustees, resulting in an accumulated
liability of $71,775 as of August 31, 2004.

      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 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.

- --------------------------------------------------------------------------------
EXPENSE OFFSET ARRANGEMENT. The reduction of custodian fees, if applicable,
represents earnings on cash balances maintained by the Fund.

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

OTHER. The preparation of financial statements in conformity with 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 over $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 year ended August 31, 2004, the Fund paid
$702,371 to OFS for services to the Fund.

      Additionally, Class Y shares are subject to minimum fees of $10,000 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
quarterly 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 quarterly 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
years. 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% per year on
Class B and Class C shares and 0.25% per year on Class N shares. The Distributor
also receives a service fee of up to 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 August 31, 2004
for Class B, Class C and Class N shares were $1,157,182, $335,644 and $11,475,
respectively. Fees incurred by the Fund under the plans are detailed in the
Statement of Operations.

PAYMENTS AND WAIVERS OF EXPENSES. Following a review of its use of brokerage
commissions for sales that is permitted under its investment advisory agreement,
the Fund's Manager terminated that practice in July 2003. Subsequently, the
Manager paid the Fund $34,012, an amount equivalent to certain of such
commissions incurred in prior years.

      OFS has voluntarily agreed to limit transfer and shareholder servicing
agent fees for all classes to 0.35% of average daily net assets per fiscal year
for all classes. During the year ended August 31, 2004, OFS waived $245,427,
$164,669, $54,577 and $3,162 for Class A, Class B, Class C and Class N shares,
respectively. This undertaking may be amended or withdrawn at any time.

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

As of August 31, 2004, 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.
The aggregate value of illiquid or restricted securities subject to this
limitation as of August 31, 2004 was $317,105, which represents 0.18% of the
Fund's net assets, all of which is considered restricted. Information concerning
restricted securities is as follows:

6. LITIGATION

Six complaints have been filed as putative derivative and class actions against
the Manager, OFS and the Distributor (collectively, "OppenheimerFunds"), as well
as 51 of the Oppenheimer funds (collectively, the "Funds") including this Fund,
and nine directors/trustees of certain of the Funds (collectively, the
"Directors/Trustees"). The complaints allege that the Manager charged excessive
fees for distribution and other costs, improperly used assets of the Funds in
the form of directed brokerage commissions and 12b-1 fees to pay brokers to
promote sales of the Funds, and failed to properly disclose the use of Fund
assets to make those payments in violation of the Investment Company Act of 1940
and the Investment Advisers Act of 1940. The complaints further allege that by
permitting and/or participating in those actions, the Directors/Trustees
breached their fiduciary duties to Fund shareholders under the Investment
Company Act of 1940 and at common law.

      OppenheimerFunds believes that it is premature to render any opinion as to
the likelihood of an outcome unfavorable to them, the Funds or the
Directors/Trustees and that no estimate can yet be made with any degree of
certainty as to the amount or range of any potential loss. However,
OppenheimerFunds, the Funds and the Directors/Trustees believe that the
allegations contained in the complaints are without merit and intend to defend
these lawsuits vigorously.

THE BOARD OF TRUSTEES AND SHAREHOLDERS OF OPPENHEIMER ENTERPRISE FUND:

We have audited the accompanying statement of assets and liabilities of
Oppenheimer Enterprise Fund, including the statement of investments, as of
August 31, 2004, and the related statement of operations for the year then
ended, the statements of changes in net assets for each of the two years in the
period then ended, and the financial highlights for each of the five years in
the period then ended. These financial statements and financial highlights are
the responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

      We conducted our audits in accordance with the standards of the Public
Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material misstatement.
An audit includes examining, on a test basis, evidence supporting the amounts
and disclosures in the financial statements. Our procedures included
confirmation of securities owned as of August 31, 2004, by correspondence with
the custodian. An audit also includes assessing the accounting principles used
and significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

      In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of
Oppenheimer Enterprise Fund as of August 31, 2004, the results of its operations
for the year then ended, the changes in its net assets for each of the two years
in the period then ended, and the financial highlights for each of the five
years in the period then ended, in conformity with U.S. generally accepted
accounting principles.
