REPORT HIGHLIGHTS

The Fund avoided much of the market's high levels of volatility, and surpassed
the S&P 500's total rate of return for the reporting period ended August 31,
2000.
We reduced our technology holdings in late 1999, limiting the impact of the
downturn in technology that occurred in March, April and May of 2000.
We emphasized holdings in the energy sector, which benefited from rising prices
for oil and gas during most of 2000.

Dear Shareholder,

Over the past several decades, our investment teams have learned the importance
of avoiding complacency when it comes to navigating the financial
markets--especially when times are good. Right now, times appear particularly
good. The U.S. economy is in its tenth year of expansion. In the bond market,
U.S. Treasury issues have been performing favorably over the past year. In
addition, despite volatility in the second quarter, the stock market has been
providing attractive returns from a wide spectrum of industry sectors,
capitalization ranges and investment styles.
   We have arrived at this juncture after months of monitoring the rapid pace of
global economic growth and its implications for inflation, as well as the
Federal Reserve Board's evolving monetary policy. At this point, economic
indicators suggest a dampening of short-term inflationary pressures. While
recent increases in oil prices are certainly taking their toll, we don't believe
this signals a return to 1970's-style inflation. Accordingly, if the Fed
continues in its diligence, the economy could maintain its healthy rate of
growth.
   In the bond market, the achievement of a federal budget surplus has prompted
the Treasury to buy back many of its long-term securities. The resulting supply
shortage boosted these securities' returns, causing an inversion of the yield
curve--an unusual situation in which shorter term Treasuries yield more than
their longer term counterparts. Other bond sectors are offering many
opportunities in the form of attractive valuations.
   Perhaps most important is that we have begun to see encouraging signs in the
stock market. Formerly high-flying Internet stocks have generally come down to
earth, and investors have

PRESIDENT'S LETTER


begun to refocus on companies with strong business fundamentals and justifiable
valuations. Investors have also returned to long-neglected, value-oriented
companies.
    What else do these various trends tell us? They tell us that the ability to
discriminate between long-term potential and short-lived fads has become more
critical than ever. Trying to generate good long-term performance requires
tracking the best companies through intensive research, combined with
hard-earned experience.
    At OppenheimerFunds, our seasoned portfolio management teams fight
complacency by remaining constantly aware of the risks that face the economy and
financial markets. Virtually anything could affect the overall markets--a surge
in inflation, a decline in productivity, deteriorating corporate earnings, or
even the new Administration's proposals regarding tax reform, healthcare and
Social Security. However, by remaining vigilant in our quest for fundamentally
sound businesses, we believe we can find good investments that can weather
market volatility.
    In this environment, we encourage you to consult your financial advisor and
to stay on track with your long-term financial plan. For our part, we will
continue to monitor the opportunities and risks ever present in the financial
markets. Thank you for your confidence in OppenheimerFunds, The Right Way to
Invest.

Sincerely,
/s/ James C. Swain           /s/ Bridget A. Macaskill

AN INTERVIEW WITH YOUR FUND'S MANAGERS

Portfolio Management
Team (l to r)

Q How would you characterize the Fund's performance during the one-year period
that ended August 31, 2000?
A. We are pleased with Oppenheimer Main Street(R) Growth & Income Fund's
performance during the recent fiscal year. The Fund avoide much of the
volatility that characterized equity markets during the period. The Fund's Class
A shares generated a 17.74% average annual total return, without sales charge,
for the period that ended August 31, 2000, outperforming its benchmark for the
same one-year time period. The S&P 500 produced a 16.32% return.(1)
   We attribute these results to our disciplined investment approach, which uses
state-of-the-art quantitative analysis to help identify stocks that we believe
are well positioned to outperform the overall market over the long term. We made
several improvements to our stock-selection process and portfolio-management
techniques during the period, which we believe contributed to the Fund's
positive performance.

What made this such a volatile period?
Throughout the period, investors struggled to weigh the positive impact of
encouraging economic trends against the negative impact of rising interest
rates. In late 1999, equity markets were driven higher by continued strength in
the U.S. economy, low rates of inflation, growing evidence of global economic
recovery and diminishing fears of Y2K-related problems. However, concerned that
the U.S. economy's rate of growth could give rise to inflation, the Federal
Reserve Board (the Fed) began to raise interest rates. Rate hikes generally tend
to hurt the valuation of stocks, because they raise the cost of borrowed capital
and reduce the present value of earnings.

AN INTERVIEW WITH YOUR FUND'S MANAGERS


   Accordingly, as the Fed continued to raise interest rates in 2000, many
segments of the equity market sagged. Yet, despite interest-rate concerns,
investors seemed willing to pay increasingly higher prices for the high-growth
potential of many technology-related stocks. Market strength became increasingly
concentrated in a relatively small number of technology stocks, driving the
valuations of these companies to extremely high levels by March 2000.
   During the second quarter of 2000, interest rate concerns finally took their
toll on technology stocks, causing many of the highest flying stocks in the
sector to fall as rapidly as they had risen. Investors showed renewed concern
about company fundamentals and profitability, shifting the focus of market
strength from growth- to value-oriented stocks in April and May. In June, July
and August, however, better-than-expected corporate earnings reports--along with
preliminary signs that U.S. economic growth might be slowing in response to the
Fed's measures--helped bolster investor confidence and gave new impetus to the
broad equity markets. A number of sectors participated in this rally, including
technology, energy and healthcare.

How did you manage the Fund in light of these conditions?
Our quantitative cap-size model generally ranked large-cap stocks higher than
smaller stocks in the prevailing market environment. As a result, we raised the
cap size of our holdings from slightly smaller than the average of the S&P 500
Index at the beginning of the period to slightly larger at the end of the
period. This shift generally benefited the Fund's performance for the period as
a whole.
   Our analytical models also helped us limit the impact of technology stock
volatility on the Fund's performance. In late 1999, our models indicated that
technology stock valuations might be unsustainably high. We responded by
reducing our

contributed to the Fund's positive performance."

<PAGE>

technology holdings to a significantly lower proportion of the portfolio,
compared with the S&P 500. While we missed some of technology's upside
performance in early 2000, we also avoided some of the downturn that occurred
when the technology bubble deflated in March, April and May. As technology
prices fell, we took advantage of the opportunity to increase our holdings among
the sector's larger, better established companies.
   We achieved strong performance from investments in other sectors of the
economy as well. Our analytical models led us to allocate a considerably higher
percentage of the Fund's assets to energy than did the S&P 500 Index. We
achieved strong returns from these holdings, which benefited from steadily
rising prices for oil and gas, and consolidations among several of the
industry's key players.

Did any of the Fund's investments fail to meet your expectations?
Our financial industry holdings were pressured by the rising interest rate
environment. Rising rates tend to be detrimental to the profitability and asset
quality of banks and insurance companies, and thus have a disproportionately
negative impact on financial services stocks. However, the Fund's performance,
compared to the S&P 500, benefited from our decision to allocate a relatively
small portion of the portfolio to the financial sector.
   Of course, not all of our investment decisions proved equally effective. We
held relatively large positions in consumer cyclicals, a sector that generally
performed poorly. We also held relatively small positions in healthcare, which
showed surprising strength. In general, however, our investment decisions helped
enable the Fund to produce returns superior to our benchmark, while avoiding
some of the market's volatility. This helped the Fund's investors enjoy a
relatively smooth ride during the last fiscal year as a result.

AN INTERVIEW WITH YOUR FUND'S MANAGERS

What kinds of improvements did you make to the Fund's stock selection process
and portfolio management techniques?
We continually refine our investment process, emphasizing analytical factors we
believe are most likely to predict relative stock performance in the prevailing
environment. We implemented several such refinements during the recent fiscal
year. For example, successful companies often start as fast-growing enterprises
and later mature into slower growing, larger firms with more pronounced value
characteristics. As companies make this transition, investors' attitudes toward
the company change, causing changes in the behavior of the stock. We have
incorporated new predictive factors in our models that helped focus on the
pattern of these changes so that we can seek to better manage the Fund's
holdings in light of evolving investor psychology.

What is your outlook for the coming months?
The outlook for interest rates and economic growth remains cloudy. Until
conditions become clearer, we believe that market volatility is likely to remain
high. Our quantitative cap-size model now suggests that large-cap and mid-cap
stocks are generally likely to outperform mega-caps in the period ahead.
Additional models suggest maintaining a balance of growth and value factors in
identifying the stocks best able to weather market volatility and participate in
market strength. Of course, we seek to constantly evolve our models in response
not only to changing stock data, but also to changing market dynamics. Combining
our models with our many years of portfolio management experience helps provide
us with powerful tools for running a successful fund.

   Whatever the coming year brings, we remain committed to our balanced,
disciplined investment approach. We continue to sharpen the strategies that have
worked well for us in the past, and that, we believe, continue to make
Oppenheimer Main Street Growth & Income Fund a core part of The Right Way to
Invest.

FUND PERFORMANCE

How Has the Fund Performed?

Below is a discussion, by the Manager, of the Fund's performance during its
fiscal year ended August 31, 2000, followed by a graphical comparison of the
Fund's performance to an appropriate broad-based market index.

Management's discussion of performance. During the fiscal year that ended August
31, 2000, the U.S. economy enjoyed strong growth. Market strength was
concentrated in technology stocks in late 1999 and early 2000. Guided by our
quantitative investment models, we reduced the Fund's technology holdings as
valuations rose to extreme levels. We emphasized large-cap stocks and
energy-related holdings, and maintained a balance between value- and
growth-oriented stocks. In mid-March 2000, concerns over rising interest rates
caused technology stocks to fall sharply, and shifted the market's direction in
favor of value-oriented stocks until late May. Energy stocks performed well in
response to rising oil and gas prices. Broad markets rallied in June, July and
August in the face of strong earnings reports and mounting evidence that
economic growth was slowing to a sustainable rate. We achieved our strongest
returns from technology and energy, while consumer cyclicals detracted from our
overall performance. The Fund's portfolio holdings, allocations and strategies
are subject to change.
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, 2000. In the case of Class A shares, performance is
measured over a ten-year period; in the case of Class B shares, from the
inception of the class on October 3, 1994; in the case of Class C shares, from
the inception of the class on December 1, 1993; and in the case of Class Y
shares, from the


8 | OPPENHEIMER MAIN STREET GROWTH & INCOME FUND
<PAGE>



inception of the class on November 1, 1996. The graphs reflect the deduction of
the maximum initial sales charge on Class A shares and the applicable contingent
deferred sales charge for Class B and Class C shares, and reinvestment of all
dividends and capital distributions.
   The Fund's performance is compared to the performance of the Standard &
Poor's (S&P) 500 Index. The S&P 500 Index is a broad-based index of equity
securities widely regarded as a general measurement of the performance of the
U.S. equity securities market. Index performance reflects the reinvestment of
dividends but does not consider the effect of capital gains or transaction cost,
and none of the data in the graphs shows the effect of taxes. The Fund's
performance reflects the effects of Fund 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
securities in the S&P 500 Index, which tend to be securities of larger,
well-capitalized companies.

NOTES

In reviewing performance and rankings, please remember that past performance
does not guarantee future results. Investment return and principal value of an
investment in the Fund will fluctuate so that an investor's shares, when
redeemed, may be worth more or less than the original cost. Because of ongoing
market volatility, the Fund's performance may be subject to substantial
short-term changes. For quarterly updates on the Fund's performance, please
contact your financial advisor, call us at 1.800.525.7048 or visit our website
at www.oppenheimerfunds.com.

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 show the effects 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.

NOTES TO FINANCIAL STATEMENTS

================================================================================
1. Significant Accounting Policies
Oppenheimer Main Street(R) Growth & Income Fund (the Fund) is a separate series
of Oppenheimer Main Street Funds, Inc., an open-end management investment
company registered under the Investment Company Act of 1940, as amended. The
Fund's investment objective is to seek a high total return, which includes
current income and capital appreciation in the value of its shares, from equity
and debt securities. The Fund's investment advisor is OppenheimerFunds, Inc.
(the Manager).
     The Fund offers Class A, Class B, Class C 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 and Class C shares are sold without a
front-end sales charge but may be subject to a contingent deferred sales charge
(CDSC). Class Y shares are sold to certain institutional investors without
either a front-end sales charge or a CDSC. All classes of shares have identical
rights to earnings, assets and voting privileges, except that each class has its
own expenses directly attributable to that class and exclusive voting rights
with respect to matters affecting that class. Classes A, B and C 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. Securities listed or traded on National Stock Exchanges or
other domestic or foreign exchanges are valued based on the last sale price of
the security traded on that exchange prior to the time when the Fund's assets
are valued. In the absence of a sale, the security is valued at the last sale
price on the prior trading day, if it is within the spread of the closing bid
and asked prices, and if not, at the closing bid price. Securities (including
restricted securities) for which quotations are not readily available are valued
primarily using dealer-supplied valuations, a portfolio pricing service
authorized by the Board of Directors, or at their fair value. Fair value is
determined in good faith under consistently applied procedures under the
supervision of the Board of Directors. 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 accounting records of the Fund are maintained
in U.S. dollars. Prices of securities denominated in foreign currencies are
translated into U.S. dollars at the closing rates of exchange. 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.
     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.


36 | OPPENHEIMER MAIN STREET GROWTH & INCOME FUND
<PAGE>


--------------------------------------------------------------------------------
Repurchase Agreements. The Fund requires the custodian to take possession, to
have legally segregated in the Federal Reserve Book Entry System or to have
segregated within the custodian's vault, all securities held as collateral for
repurchase agreements. The market value of the underlying securities is required
to be at least 102% of the resale price at the time of purchase. If the seller
of the agreement defaults and the value of the collateral declines, or if the
seller enters an insolvency proceeding, realization of the value of the
collateral by the Fund may be delayed or limited.
--------------------------------------------------------------------------------
Allocation of Income, Expenses, Gains and Losses. Income, expenses (other than
those attributable to a specific class), gains and losses are allocated daily 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 continue to comply with provisions of the
Internal Revenue Code applicable to regulated investment companies and to
distribute all of its taxable income, including any net realized gain on
investments not offset by loss carryovers, to shareholders. Therefore, no
federal income or excise tax provision is required.
--------------------------------------------------------------------------------
Dividends and Distributions to Shareholders. Dividends and distributions to
shareholders, which are determined in accordance with income tax regulations,
are recorded on the ex-dividend date.
--------------------------------------------------------------------------------
Classification of Dividends and Distributions to Shareholders. Net investment
income (loss) and net realized gain (loss) may differ for financial statement
and tax purposes. The character of dividends and distributions made during the
fiscal year from net investment income or net realized gains may differ from its
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 realized gain was
recorded by the Fund.
     The Fund adjusts the classification of distributions to shareholders to
reflect the differences between financial statement amounts and distributions
determined in accordance with income tax regulations. Accordingly, during the
year ended August 31, 2000, amounts have been reclassified to reflect an
increase in paid-in capital of $84,966,366, a decrease in undistributed net
investment income of $785,963, and a decrease in accumulated net realized gain
on investments of $84,180,403. This reclassification includes $84,966,366
distributed in connection with Fund share redemptions which increased paid-in
capital and reduced accumulated net realized gain. Net assets of the Fund were
unaffected by the reclassifications.
--------------------------------------------------------------------------------
Expense Offset Arrangements. Expenses paid indirectly represent a reduction of
custodian fees for earnings on cash balances maintained by the Fund.

NOTES TO FINANCIAL STATEMENTS  Continued


================================================================================
1. Significant Accounting Policies Continued
Other. Investment transactions are accounted for as of trade date and dividend
income is recorded on the ex-dividend date. Certain dividends from foreign
securities will be recorded as soon as the Fund is informed of the dividend if
such information is obtained subsequent to the ex-dividend date. Realized gains
and losses on investments and unrealized appreciation and depreciation are
determined on an identified cost basis, which is the same basis used for federal
income tax purposes.
     The preparation of financial statements in conformity with 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.
================================================================================
2. Capital Stock
The Fund has authorized 840 million shares of $.01 par value capital stock (400
million for Class A, 300 million for Class B, 100 million for Class C and 40
million for Class Y). Transactions in shares of capital stock were as follows:

the first $200 million of average annual net assets of the Fund, 0.60% of the
next $150 million, 0.55% of the next $150 million and 0.45% of average annual
net assets in excess of $500 million. The Fund's management fee for the year
ended August 31, 2000, was an annualized rate of 0.45%, before any waiver by the
Manager if applicable.
--------------------------------------------------------------------------------
Transfer Agent Fees. OppenheimerFunds Services (OFS), a division of the Manager,
acts as the transfer and shareholder servicing agent for the Fund on an
"at-cost" basis. OFS also acts as the transfer and shareholder servicing agent
for the other Oppenheimer funds.
--------------------------------------------------------------------------------
Distribution and Service Plan Fees. Under its General Distributor's Agreement
with the Manager, the Distributor acts as the Fund's principal underwriter in
the continuous public offering of the different classes of shares of the Fund.

servicing of the shares of the particular class.

NOTES TO FINANCIAL STATEMENTS  Continued

================================================================================
4. Fees and Other Transactions with Affiliates Continued
Class A Service Plan Fees. Under the Class A service plan, the Distributor
currently uses the fees it receives from the Fund to pay brokers, dealers and
other financial institutions. The Class A service plan permits reimbursements to
the Distributor at a rate of up to 0.25% of average annual net assets of Class A
shares purchased. The Distributor makes payments to plan recipients quarterly at
an annual rate not to exceed 0.25% of the average annual net assets consisting
of Class A shares of the Fund. For the year ended August 31, 2000, payments
under the Class A plan totaled $20,566,486 prior to Manager waivers if
applicable, all of which were paid by the Distributor to recipients, and
included $1,142,760 paid to an affiliate of the Manager. Any unreimbursed
expenses the Distributor incurs with respect to Class A shares in any fiscal
year cannot be recovered in subsequent years.
--------------------------------------------------------------------------------
Class B and Class C Distribution and Service Plan Fees. Under each plan, service
fees and distribution fees are computed on the average of the net asset value of
shares in the respective class, determined as of the close of each regular
business day during the period. The Class B and Class C plans provide for the
Distributor to be compensated at a flat rate, whether the Distributor's
distribution expenses are more or less than the amounts paid by the Fund under
the plan during the period for which the fee is paid.
     The Distributor retains the asset-based sales charge on Class B shares. The
Distributor retains the asset-based sales charge on Class C shares during the
first year the shares are outstanding. The asset-based sales charges on Class B
and Class C shares allow investors to buy shares without a front-end sales
charge while allowing the Distributor to compensate dealers that sell those
shares.
     The Distributor's actual expenses in selling Class B and Class C shares may
be more than the payments it receives from the contingent deferred sales charges
collected on redeemed shares and asset-based sales charges from the Fund under
the plans. If any plan is terminated by the Fund, the Board of Directors may
allow the Fund to continue payments of the asset-based sales charge to the
Distributor for distributing shares before the plan was terminated. The plans
allow for the carry-forward of distribution expenses, to be recovered from
asset-based sales charges in subsequent fiscal periods.

Distribution fees paid to the Distributor for the year ended August 31, 2000,
were as follows:

================================================================================
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 for operational purposes and to seek to protect against
adverse exchange rate fluctuations. Risks to the Fund include the potential
inability of the counterparty to meet the terms of the contract.
     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 foreign currency exchange rates as provided by
a reliable bank, dealer or pricing service. Unrealized appreciation and
depreciation on foreign currency contracts are reported in the Statement of
Assets and Liabilities.
     The Fund may realize a gain or loss upon the closing or settlement of the
foreign currency transactions. Realized gains and losses are reported with all
other foreign currency gains and losses in the Statement of Operations.
     Securities denominated in foreign currency to cover net exposure on
outstanding foreign currency contracts are noted in the Statement of Investments
where applicable.
================================================================================
6. Bank Borrowings
The Fund may borrow from a bank for temporary or emergency purposes including,
without limitation, funding of shareholder redemptions provided asset coverage
for borrowings exceeds 300%. The Fund has entered into an agreement which
enables it to participate with other Oppenheimer funds in an unsecured line of
credit with a bank, which permits borrowings up to $400 million, collectively.
Interest is charged to each fund, based on its borrowings, at a rate equal to
the Federal Funds Rate plus 0.45%. Borrowings are payable 30 days after such
loan is executed. The Fund also pays a commitment fee equal to its pro rata
share of the average unutilized amount of the credit facility at a rate of 0.08%
per annum.
     The Fund had no borrowings outstanding during the year ended August 31,
2000.
================================================================================
7. Other Matters
On April 13, 2000, the Board of Directors approved the reorganization of
Oppenheimer Disciplined Value Fund with and into Oppenheimer Main Street Growth
& Income Fund. Shareholders of the Oppenheimer Disciplined Value Fund will be
asked to approve a reorganization whereby shareholders would receive shares of
Oppenheimer Main Street Growth & Income Fund. If shareholder approval is
received, it is expected that the reorganization will occur during the fourth
quarter of calendar 2000.

INDEPENDENT AUDITORS' REPORT


================================================================================
To the Board of Directors and Shareholders of
Oppenheimer Main Street Growth & Income Fund:

We have audited the accompanying statement of assets and liabilities of
Oppenheimer Main Street Growth & Income Fund, including the statement of
investments, as of August 31, 2000, 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
four years in the period then ended, the two-month period ended August 31, 1996,
and the one-year ended June 30, 1996. 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 auditing standards generally
accepted in the United States of America. 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, 2000, by correspondence with the custodian and
brokers; where replies were not received from brokers, we performed other
auditing procedures. 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 Main Street Growth & Income Fund as of August 31, 2000, 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 four years in the period then ended, the two-month period ended
August 31, 1996, and the one-year ended June 30, 1996, in conformity with
accounting principles generally accepted in the United States of America.

FEDERAL INCOME TAX INFORMATION  Unaudited


================================================================================
In early 2001 shareholders will receive information regarding all dividends and
distributions paid to them by the Fund during calendar year 2000. Regulations of
the U.S. Treasury Department require the Fund to report this information to the
Internal Revenue Service.
     Dividends and distributions of $4.4805 per share were paid to Class A,
Class B, Class C and Class Y shareholders, on December 3, 1999, of which $4.0105
was designated as a "capital gain distribution" for federal income tax purposes.
Whether received in stock or in cash, the capital gain distribution should be
treated by shareholders as a gain from the sale of capital assets held for more
than one year (long-term capital gains).
     Dividends paid by the Fund during the fiscal year ended August 31, 2000,
which are not designated as capital gain distributions should be multiplied by
100% to arrive at the net amount eligible for the corporate dividend-received
deduction.
     The foregoing information is presented to assist shareholders in reporting
distributions received from the Fund to the Internal Revenue Service. Because of
the complexity of the federal regulations which may affect your individual tax
return and the many variations in state and local tax regulations, we recommend
that you consult your tax advisor for specific guidance.
