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, 2006, FOLLOWED BY
A GRAPHICAL COMPARISON OF THE FUND'S PERFORMANCE TO AN APPROPRIATE BROAD-BASED
MARKET INDEX.

MANAGEMENT'S DISCUSSION OF FUND PERFORMANCE. For the 12-month period ended
August 31, 2006, the Fund produced flat performance and trailed behind its
benchmark, the S&P 500 Index. In a market environment, described below, where
investors reduced their appetite for risk, our technology and biotechnology
holdings underperformed.

      Shareholders should expect us to continue to adhere to our
research-driven, bottom-up long-term stock selection investment strategy. We
look for market leaders and emerging market leaders in high growth industries
across all market capitalizations. Our focus is on well-managed businesses with
strong financials and sustainable competitive advantages, which we have
determined are attractively valued. We invest with a minimum one-year time frame
and seek to identify a long-term investment thesis for each and every
investment. In situations where we believe our longer-term thesis has been
altered or compromised, we will exit or reduce our holding. If and when our
long-term, internally generated, price targets are reached, we will exit our
position. We believe that continuing to follow our investment process,
regardless of the market environment, is the best approach to serving our
shareholders over the long-term.

      Although we conduct intensive research on all of the companies that we
select for the portfolio, unanticipated events arise, as occurred over the
period with a number of the Fund's holdings. Underperformance was derived from
holdings within the technology, healthcare and consumer discretionary sectors.
Within technology, detractors included Maxim Integrated Products, Inc., and
eBay, Inc. Maxim Integrated Products, Inc., a leading supplier of mixed-signal
(analog and digital) semiconductors, declined as a result a cyclical downturn in
its niche market. eBay, Inc., the leading electronic auction marketplace, also
detracted from Fund performance as it underperformed due to negative market
reaction to its expanded business model--an idea conceived by management to
enhance its long-term business prospects. This company's proven management team
is focused on the long-term, something we as long-term investors, are attracted
to.

      Within biotechnology, Martek Biosciences Corp., a manufacturer and seller
of nutritional additives found in infant formula, detracted from the Fund's
results. Martek Biosciences Corp. came under pressure after a series of
management missteps and new lower cost competitive products came to market. Due
to the nature of these issues, we no longer had confidence in our long-term
investment thesis and sold our holdings. Lastly, specialty retailer, Urban
Outfitters, Inc., suffered as the company failed to correctly position its
apparel line for

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

the latest fashion trends. However, fashion misses are a reality of this
business, our confidence in management remains, and we have maintained our
position.

      On the positive side of performance, the Fund received strong
contributions from stocks in such diverse industries as telecommunication
services, IT services, capital markets and medical equipment. Within the
telecommunication services area, American Tower Corp. posted our strongest
performance. American Tower Corp., which manages and operates communication
towers for cellular phone transmission, benefited from the tremendous growth
seen in the cellular phone industry. Cognizant Technology Solutions Corp., an
offshore outsourcing IT services provider, posted strong results as this market
continued to grow rapidly. Google, Inc., gained market share and participated
fully in the rapidly expanding market for internet search.

      In the financials sector, Goldman Sachs Group, Inc. (The) benefited from a
high level of mergers and acquisition activity over the period. Lastly in
healthcare, Varian Medical Systems, Inc., a manufacturer and seller of x-ray and
oncology products, performed well over the reporting period. The company
continues to benefit from a successful product cycle as proven by its strong
product sales.

      Lastly, as a result of our bottom-up stock selection investment process,
we brought the Fund's average market capitalization down to levels that are now
below both the Russell 3000 Growth Index and the Lipper Multi Cap Growth Fund
peer group average. 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, 2006. In the case of Class A,
Class B and Class C shares, performance is measured over a ten-fiscal-year
period; 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


                        10 | OPPENHEIMER ENTERPRISE FUND


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.

Inc.

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

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 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.

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


                        19 | OPPENHEIMER ENTERPRISE FUND


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

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 184/365
(to reflect the one-half year period). Those annualized expense ratios based on
the 6-month period ended August 31, 2006 are as follows:

CLASS                EXPENSE RATIOS
- -----------------------------------
Class A                   1.42%
- -----------------------------------
Class B                   2.19
- -----------------------------------
Class C                   2.17

Class N                   1.58
- -----------------------------------
Class Y                   0.93

The expense ratios reflect voluntary waivers or 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
waivers or 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 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 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.


                        34 | OPPENHEIMER ENTERPRISE FUND


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.

The tax components of capital shown in the table below represent distribution
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.

2. During the fiscal year ended August 31, 2006, the Fund utilized $6,552,115 of
capital loss carryforward to offset capital gains realized in that fiscal year.

3. During the fiscal year ended August 31, 2005, the Fund utilized $15,837,193
of capital loss carryforward to offset capital gains realized in that fiscal
year.

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, 2006. Net assets of the
Fund were unaffected by the reclassifications.

1. SIGNIFICANT ACCOUNTING POLICIES Continued

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, 2006 are noted below. The primary
difference between book and tax appreciation or depreciation of securities and
other investments, if applicable, is attributable to the tax deferral of losses
or tax realization of financial statement unrealized gain or loss.

           Federal tax cost of securities        $211,532,675
                                                 =============

           Gross unrealized appreciation         $ 31,014,330
           Gross unrealized depreciation          (11,284,014)

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

Certain foreign countries impose a tax on capital gains which is accrued by the
Fund based on unrealized appreciation, if any, on affected securities. The tax
is paid when the gain is realized.

- --------------------------------------------------------------------------------
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, 2006, the Fund's projected benefit obligations were decreased by $13,550 and
payments of $4,846 were made to retired trustees, resulting in an accumulated
liability of $42,833 as of August 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 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

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.

investment advisory agreement with the Fund which provides for a fee at an
average annual rate as shown in the following table:

        FEE SCHEDULE
        ----------------------------------------------
        Up to $200 million of net assets         0.75%

        Over $1.5 billion of net assets          0.58

$688,050 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.


                        38 | OPPENHEIMER ENTERPRISE FUND


- --------------------------------------------------------------------------------
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 August 31, 2006 for Class B, Class C
and Class N shares were $907,276, $408,988 and $46,897, 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.

4. FEES AND OTHER TRANSACTIONS WITH AFFILIATES Continued

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 year ended August 31, 2006, OFS
waived $184,577, $3,253, $20,151, $87,159 and $739 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. RECENT ACCOUNTING PRONOUNCEMENT

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
August 31, 2006, the Manager is evaluating the implications of FIN 48. Its
impact in the Fund's financial statements has not yet been determined.

- --------------------------------------------------------------------------------
6. LITIGATION

A consolidated amended complaint was filed as a putative class action against
the Manager and the Transfer Agent and other defendants (including 51 of the
Oppenheimer funds including the Fund) 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 the allegations contained in the complaint are
without merit and that there are substantial grounds to sustain the district
court's rulings. The Manager also believes that it is premature to render any
opinion as to the likelihood of an outcome unfavorable to it, 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.

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, 2006, and the related statement of operations for the year then
ended, the statements of changes in net assets for each of the years in the
two-year period then ended, and the financial highlights for each of the years
in the five-year 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, 2006, 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, 2006, the results of its operations
for the year then ended, the changes in its net assets for each of the years in
the two-year period then ended, and the financial highlights for each of the
years in the five-year period then ended, in conformity with U.S. generally
accepted accounting principles.

ITEM 2. CODE OF ETHICS.

The registrant has adopted a code of ethics that applies to the registrant's
principal executive officer, principal financial officer, principal accounting
officer or controller or persons performing similar functions.

ITEM 3. AUDIT COMMITTEE FINANCIAL EXPERT.

The Board of Trustees of the registrant has determined that the registrant does
not have an audit committee financial expert serving on its Audit Committee. In
this regard, no member of the Audit Committee was identified as having all of
the technical attributes identified in Instruction 2(b) to Item 3 of Form N-CSR
to qualify as an "audit committee



financial expert," whether through the type of specialized education or
experience described in that Instruction. The Board has concluded that while the
members of the Audit Committee collectively have the necessary attributes and
experience required to serve effectively as an Audit Committee, no single member
possesses all of the required technical attributes through the particular
methods of education or experience set forth in the Instructions to be
designated as an audit committee financial expert.

ITEM 4. PRINCIPAL ACCOUNTANT FEES AND SERVICES.

(a)   Audit Fees

The principal accountant for the audit of the registrant's annual financial
statements billed $13,000 in fiscal 2006 and $13,000 in fiscal 2005.

(b)   Audit-Related Fees

The principal accountant for the audit of the registrant's annual financial
statements billed no such fees during the last two fiscal years.

The principal accountant for the audit of the registrant's annual financial
statements billed $75,000 in fiscal 2006 and $132,059 in fiscal 2005 to the
registrant's investment adviser or any entity controlling, controlled by, or
under common control with the adviser that provides ongoing services to the
registrant.

Such services include: internal control reviews.

(c)   Tax Fees

The principal accountant for the audit of the registrant's annual financial
statements billed no such fees to the registrant during the last two fiscal
years.

The principal accountant for the audit of the registrant's annual financial
statements billed no such fees in fiscal 2006 and $5,000 in fiscal 2005 to the
registrant's investment adviser or any entity controlling, controlled by, or
under common control with the adviser that provides ongoing services to the
registrant.

Such services include: filing form 5500.

(d)   All Other Fees

The principal accountant for the audit of the registrant's annual financial
statements billed no such fees during the last two fiscal years.

The principal accountant for the audit of the registrant's annual financial
statements billed $8,000 in fiscal 2006 and no such fees in 2005 to the
registrant's investment



adviser or any entity controlling, controlled by, or under common control with
the adviser that provides ongoing services to the registrant.

Such fees would include the cost to the principal accountant of attending audit
committee meetings and consultations regarding the registrant's retirement plan
with respect to its trustees.

(e)   (1) During its regularly scheduled periodic meetings, the registrant's
      audit committee will pre-approve all audit, audit-related, tax and other
      services to be provided by the principal accountants of the registrant.

      The audit committee has delegated pre-approval authority to its Chairman
      for any subsequent new engagements that arise between regularly scheduled
      meeting dates provided that any fees such pre-approved are presented to
      the audit committee at its next regularly scheduled meeting.

      Under applicable laws, pre-approval of non-audit services maybe waived
      provided that: 1) the aggregate amount of all such services provided
      constitutes no more than five percent of the total amount of fees paid by
      the registrant to it principal accountant during the fiscal year in which
      services are provided 2) such services were not recognized by the
      registrant at the time of engagement as non-audit services and 3) such
      services are promptly brought to the attention of the audit committee of
      the registrant and approved prior to the completion of the audit.

      (2) 100%

(f)   Not applicable as less than 50%.

(g)   The principal accountant for the audit of the registrant's annual
      financial statements billed $83,000 in fiscal 2006 and $137,059 in fiscal
      2005 to the registrant and the registrant's investment adviser or any
      entity controlling, controlled by, or under common control with the
      adviser that provides ongoing services to the registrant related to
      non-audit fees. Those billings did not include any prohibited non-audit
      services as defined by the Securities Exchange Act of 1934.

(h)   The registrant's audit committee of the board of trustees has considered
      whether the provision of non-audit services that were rendered to the
      registrant's investment adviser, and any entity controlling, controlled
      by, or under common control with the investment adviser that provides
      ongoing services to the registrant that were not pre-approved pursuant to
      paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with
      maintaining the principal accountant's independence.

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 08/31/2006, 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.

(a)   (1)   Exhibit attached hereto.

      (2)   Exhibits attached hereto.

      (3)   Not applicable.

(b)   Exhibit attached hereto.
