 OVERVIEW

LETTER TO SHAREHOLDERS
June 20, 2000

Dear Shareholder,

Whether you have held your fund for years or just joined the Van Kampen family
of shareholders in the last few months, you are likely to have questions and
even some concerns about how recent market volatility has affected your
investment. I encourage you to review the following Q&A in which your portfolio
manager provides an update on how your fund is being managed in this
environment.

It is times like these when money-management experience may make a difference.
Toward that end, you should know that Van Kampen is one of the nation's oldest
investment-management firms, with a history of money management dating back to
1926. Our portfolio managers have invested in all types of market
conditions--during bull and bear markets, periods of inflation and rising
interest rates, and now a technology revolution. We have managed money long
enough to understand short-term market volatility and the value of investing for
the long term.

                  As we head into the second half of 2000, count on us to
                  continue to draw on the wisdom of our 76 years of experience.
                  Along those lines, Van Kampen's "Generations of Experience" is
the theme of a national advertising campaign that kicked off this spring. The
message emphasizes our depth of investment-management history, as well as our
firm belief that with the right investments, anyone can realize life's true
wealth.

Sincerely,

ECONOMIC SNAPSHOT

ECONOMIC GROWTH
ECONOMIC GROWTH CONTINUED TO BE STRONG WITH THE GROSS DOMESTIC PRODUCT (GDP),
THE PRIMARY MEASURE OF ECONOMIC GROWTH, INCREASING TO A 5.5 ANNUALIZED
PERCENTAGE RATE IN THE FIRST QUARTER OF 2000. THIS WAS THE THIRD CONSECUTIVE
QUARTER IN WHICH THE ECONOMY GREW FASTER THAN 5 PERCENT. HIGH LEVELS OF CONSUMER
CONFIDENCE, LOW LEVELS OF UNEMPLOYMENT, AND INCREASING PRODUCTIVITY WERE PRIMARY
FACTORS UNDERLYING THE HEALTHY ECONOMY.

CONSUMER SPENDING AND EMPLOYMENT
INFLATION FEARS CONTINUED TO MOUNT BECAUSE OF STRONG CONSUMER SPENDING AND THE
TIGHT LABOR MARKET. FOR MOST OF THE REPORTING PERIOD, RISING INTEREST RATES DID
LITTLE TO REIN IN ROBUST CONSUMER SPENDING. ALTHOUGH RETAIL SALES GROWTH
MODERATED IN APRIL AND MAY, THE FACTORS UNDERPINNING CONSUMER ACTIVITY--RISING
WAGES AND LOW UNEMPLOYMENT--REMAINED LARGELY UNCHANGED.

IN ADDITION, THE JOBLESS RATE HOVERED NEAR ITS LOWEST LEVEL IN THREE DECADES.
THE EMPLOYMENT COST INDEX ACCELERATED SHARPLY IN THE FIRST QUARTER OF 2000,
REFLECTING RISING WAGES AS EMPLOYERS VIED TO ATTRACT AND RETAIN SKILLED WORKERS.
THESE WAGE PRESSURES, IN TURN, BEGAN TO AFFECT PRICES, AS COMPANIES STARTED TO
RAISE THE COST OF GOODS AND SERVICES TO COMPENSATE FOR HIGHER LABOR COSTS.

INTEREST RATES AND INFLATION
STRONG GDP NUMBERS PROMPTED THE FEDERAL RESERVE BOARD TO RAISE INTEREST RATES
AND REMAIN ACTIVE IN GUARDING AGAINST INFLATION AND TEMPERING ECONOMIC GROWTH.
THE CONSUMER PRICE INDEX (CPI) ALSO ROSE TO HIGHER LEVELS DURING THE REPORTING
PERIOD. BOTH GDP AND CPI DATA WARRANTED AN INCREASE OF SHORT-TERM RATES BY 0.25
PERCENT IN NOVEMBER AND FEBRUARY AND BY 0.50 PERCENT IN MAY.

THE PERSONAL CONSUMPTION EXPENDITURES PRICE INDEX, A MEASURE OF INFLATION
WATCHED BY FEDERAL RESERVE POLICY MAKERS, ROSE TO 3.1 PERCENT IN THE FIRST
QUARTER OF 2000. GIVEN THE FEDERAL RESERVE'S AIM TO ACHIEVE AN ECONOMIC GROWTH
RATE BETWEEN 3 AND 4 PERCENT, A RANGE THAT WOULD BE CONSIDERED LESS LIKELY TO
PROMPT HIGHER INFLATION, FURTHER INTEREST RATE HIKES MAY BE LIKELY BEFORE THE
END OF THE YEAR.

N/A = Not Applicable

(1) Assumes reinvestment of all distributions for the period and does not
include payment of the maximum sales charge (4.75% for Class A shares) or
contingent deferred sales charge ("CDSC"). On purchases of Class A shares of $1
million or more, a CDSC of 1% may be imposed on certain redemptions made within
one year of purchase. Returns for Class B shares are calculated without the
effect of the maximum 4% CDSC, charged on certain redemptions made within one
year of purchase and declining thereafter to 0% after the fifth year. Returns
for Class C shares are calculated without the effect of the maximum 1.00% CDSC,
charged on certain redemptions made within one year of purchase. If the sales
charges were included, total returns would be lower.

(2) Standardized total return. Assumes reinvestment of all distributions for the
period and includes payment of the maximum sales charge (4.75% for Class A
shares) or contingent deferred sales charge ("CDSC"). On purchases of Class A
shares of $1 million or more, a CDSC of 1% may be imposed on certain redemptions
made within one year of purchase. Returns for Class B shares are calculated with
the effect of the maximum 4% CDSC, charged on certain redemptions made within
one year of purchase and declining thereafter to 0% after the fifth year.
Returns for Class C shares are calculated with the effect of the maximum 1.00%
CDSC, charged on certain redemptions made within one year of purchase.

(3) The total return reflects the conversion of Class B shares into Class A
shares six years after the end of the calendar month in which the shares were
purchased.

(4) Distribution rate represents the monthly annualized distributions of the
Fund at the end of the period and not the earnings of the Fund.

(5) Taxable-equivalent calculations reflect a federal income tax rate of 36%.

(6) SEC Yield is a standardized calculation prescribed by the Securities and
Exchange Commission for determining the amount of net income a portfolio should
theoretically generate for the 30-day period ending May 31, 2000.

A portion of the interest income may be subject to the federal alternative
minimum tax (AMT).

An investment in the Fund is subject to investment risks, and you could lose
money on your investment in the Fund. Please review the Risk/Return Summary of
the Prospectus for further details on investment risks. Fund shares, when
redeemed, may be worth more or less than their original cost. Past performance
is no guarantee of future results. Investment return and net asset value will
fluctuate with market conditions.

Q&A WITH YOUR PORTFOLIO MANAGERS

WE RECENTLY SPOKE WITH THE MANAGEMENT TEAM OF THE VAN KAMPEN HIGH YIELD
MUNICIPAL FUND ABOUT THE KEY EVENTS AND ECONOMIC FORCES THAT SHAPED THE MARKETS
DURING THE PAST SIX MONTHS. THE TEAM IS LED BY WAYNE D. GODLIN, PORTFOLIO
MANAGER, WHO HAS MANAGED THE FUND SINCE MARCH 1990 AND HAS WORKED IN THE
INVESTMENT INDUSTRY SINCE 1984. THE FOLLOWING DISCUSSION REFLECTS HIS VIEWS ON
THE FUND'S PERFORMANCE DURING THE SIX-MONTH PERIOD ENDED MAY 31, 2000.

Q   HOW WOULD YOU DESCRIBE THE
    MARKET ENVIRONMENT IN WHICH
    THE FUND HAS OPERATED DURING
    THE PAST SIX MONTHS?

A   Although the municipal market performed poorly over the past six months,
with slightly negative returns, municipals generally performed better than other
fixed-income investments. Most corporate bonds, government bonds, and mortgage-
backed securities fared worse.

    The reason for the lackluster performance among municipal bonds was
three-fold. First, the Federal Reserve Board raised interest rates several times
during the reporting period. When long-term interest rates rise, bond prices
fall, making it difficult for interest-rate sensitive bond funds to produce
attractive returns. Second, the participants in the municipal market were
unclear as to which direction interest rates were headed. This uncertainty
resulted in a choppy market. Third, credit spreads between higher-quality AAA
rated bonds and lower-quality BBB and lower-rated bonds widened due to fears of
a slowing economy. When spreads widen, lower-rated bonds, such as those held by
the fund, typically underperform higher-quality bonds, such as those that are
insured or rated AAA.

Q   HOW DID YOU POSITION THE FUND
    IN THIS ENVIRONMENT?

A   Our approach is very similar in nature to that of many equity mutual funds,
which focus on the fundamental value of the underlying companies in which they
invest, rather than economic forecasts. We primarily evaluate municipal bonds on
an individual basis--regardless of whether credit spreads are tight or wide--and
we continue to position the fund for the long term. Our research team of eight
analysts, located throughout the country, helps us continue to maintain a highly
diversified portfolio by geography and sector, which is an important strategy
when investing in high-yield, high-risk municipal bonds. Diversification allows
us to help minimize the effects of weakness in a specific municipality or
economic sector.

                                        8
<PAGE>   10

    There was a subtle shift in the makeup of the portfolio during this
reporting period. We reduced the fund's exposure to nonrated credits at the
beginning of the period by approximately 6 to 7 percent and reallocated the
proceeds to higher-yielding, rated bonds with longer durations, without changing
the fund's distribution rate.

Q   WHAT PERCENTAGE OF THE FUND'S
    ASSETS ARE INVESTED IN NONRATED
    BONDS, AND WHY?

A   As of May 31, 2000, 80 percent of the fund's long-term investments were
invested in nonrated bonds. We believe these bonds continue to provide
exceptional value to shareholders, particularly when compared to rated municipal
bonds. The difference in yield between Aaa rated bonds and higher-risk Baa rated
bonds was only 73 basis points--5.91 percent compared to 6.64 percent as of May
31, 2000. However, by making the jump to nonrated bonds, we have the potential
to pick up another 75 to 100 basis points in yield. In addition, we've found
over the last 10 years that these bonds have tangible upside potential for three
primary reasons.

    First, there are fewer participants in the nonrated municipal market. Most
investors, including institutional and mutual fund investors, lack the
significant analytical resources and experience necessary to evaluate municipals
that haven't been rated. With fewer skilled participants, investors are in a
better position to negotiate higher yields from the issuers. Second, the risks
associated with non-rated bonds are often greater, which means the issuers must
offer potentially higher yields to investors. Third, many of the nonrated
municipals purchased by our group have improved in credit quality over long
periods of time. Their price has increased in lockstep with their real and
perceived credit quality, benefiting the fund's shareholders with capital
appreciation in addition to yield. As a result of this strategy, the fund
benefited from significant improvements in the credit quality of its holdings,
which helped to offset the effects of weakness in the overall municipal bond
market.

Q   WHAT OTHER FACTORS CONTRIBUTED
    TO THE FUND'S PERFORMANCE?

A   One factor contributing to the fund's performance was from our investments
in life-care projects. Life-care centers typically offer a mix of independent
housing, assisted living, and long-term care facilities for elderly people.
Life-care facilities, which have private payments as their primary source of
revenues, were largely unaffected by cutbacks in Medicare and Medicaid payments.
For additional fund portfolio highlights, please refer to page 6.

Q   HOW DID THE FUND PERFORM
    DURING THE PAST SIX MONTHS?

A   Considering the poor market conditions we faced during the period, the
fund's performance fared well relative to its benchmark, the Lehman Brothers
Municipal Bond Index. For the six months ended May 31, 2000, the fund's total
return

                                        9
<PAGE>   11

was -0.76 percent (Class A shares at net asset value; if the maximum sales
charge of 4.75 percent were included, the return would have been lower). The
fund's net asset value closed the reporting period at $10.54 per Class A share,
down from $10.96 at the beginning of the period. As of May 31, 2000, the fund's
Class A share tax-exempt distribution rate was 6.07 percent, representing a
taxable equivalent distribution rate of 9.48 percent for an investor in the 36
percent federal income tax bracket.

    By comparison, the Lehman Brothers Municipal Bond Index returned 1.02
percent during the same six-month period. This broad-based index of municipal
bonds does not reflect any commissions or sales charges that would be paid by an
investor purchasing the securities it represents. Such costs would lower the
performance of the index. It is not possible to invest directly in an index.
Please refer to the footnotes and chart on page 4 for additional fund
performance results. Past performance is no guarantee of future results.

Q   HOW DID THE FUND'S PERFORMANCE
    COMPARE TO THAT OF ITS PEERS?

A   As of May 2000, the fund had been rated five stars by Morningstar for 99
consecutive months--the eighth- longest five-star track record of any fund in
any Morningstar category.

    We typically have maintained a greater percentage of fund assets in
higher-yielding, lower-rated securities than other funds in our peer group,
which has historically helped the fund outpace its peer average. As of May 31,
2000, the fund's performance earned an overall rating of five stars from
Morningstar in the Municipal Bond Fund Category, which means it was ranked in
the top 10 percent of funds within its category. The fund's Class A shares
received five stars in each of the 3, 5, and 10-year periods, which were
calculated among 1,690, 1,441, and 408 funds in the municipal bond fund
category, respectively, as of May 31, 2000.

    Morningstar is an independent rating company, and the five-star composite
rating is the highest rating it assigns in its monthly mutual fund reviews.
Morningstar ratings are calculated from the fund's 3, 5, and 10-year average
annual returns (if applicable) in excess of 90-day Treasury bill returns with
appropriate fee adjustments, and a risk factor that reflects fund performance
below 90-day T-bill returns. While past performance is no guarantee of future
results, Morningstar ratings provide a means to measure a fund's ability to
achieve its investment goals. Ten percent of the funds receive five stars, 22.5
percent receive four stars, 35 percent receive three stars, 22.5 percent receive
two stars, and 10 percent receive one star.

<PAGE>   12

Q   WHAT IS YOUR OUTLOOK FOR THE
    FUND IN THE NEXT SIX MONTHS?

A   We are optimistic. Investors have been comforted by the Federal Reserve's
aggressive stance in fighting inflation, which may bring institutional investors
back into the municipal market. In addition, credit spreads are narrowing again,
which may indicate that the market is growing confident that the Fed has
inflation and economic growth under control. Yields are also back up to a level
that might capture the attention of equity investors and yield seekers.
Certainly things could change, but we believe the indicators are pointing toward
a healthier municipal market ahead.

    We will continue to focus on our strengths: conducting primary market
research and finding value in nonrated bonds. Historically, the fund has
succeeded over the long run by utilizing this strategy, and we will continue to
invest this way because we believe it works. Over time, we believe these
strengths should continue to help the fund as it seeks to achieve its investment
objective--providing shareholders with as high a level of interest income exempt
from federal income tax as is consistent with the investment policies of the
fund.

GLOSSARY OF TERMS

A HELPFUL GUIDE TO SOME OF THE COMMON TERMS YOU'RE LIKELY TO SEE IN THIS REPORT
AND OTHER FINANCIAL PUBLICATIONS.

BOND: A debt security issued by a government or corporation that pays a
bondholder a stated rate of interest and repays the principal at the maturity
date.

CLASS A SHARES: A division of mutual fund shares, which are generally divided
into three groupings, called Class A, Class B, and Class C shares. The specific
features of each are dependent on varying fees and sales charges. In most cases,
Class A shares will have no redemption fee (contingent deferred sales charge).

CREDIT RATING: An evaluation of an issuer's credit history and capability of
repaying obligations. Standard & Poor's and Moody's Investors Service are two
companies that assign bond ratings. Standard & Poor's ratings range from a high
of AAA to a low of D, while Moody's ratings range from a high of Aaa to a low of
C.

CREDIT SPREAD: Also called quality spread, the difference in yield between
higher-quality issues (such as Treasury securities) and lower-quality issues.
Normally, lower-quality issues provide higher yields to compensate investors for
the additional credit risk.

DURATION: A measure of the sensitivity of a bond's price to changes in interest
rates, expressed in years. Each year of duration represents an expected 1
percent change in the price of a bond for every 1 percent change in interest
rates. The longer a bond's duration, the greater the effect of interest rate
movements on its price. Typically, funds with shorter durations perform better
in rising rate environments, while funds with longer durations perform better
when rates decline.

MATURITY LENGTH: The time it takes for a bond to mature. A bond issued in 1999
and maturing in 2009 is a 10-year bond. For corporate bonds, short-term bonds
usually mature in five years or less, intermediate-term bonds mature in five to
ten years, and long-term bonds mature after ten years.

MUNICIPAL BOND: A debt security issued by a state, municipality, or other state
or local government entity to finance capital expenditures of public projects,
such as the construction of highways, public works, or school buildings.
Interest on public-purpose municipal bonds is exempt from federal income taxes
and, in some states, from state and local income taxes.

YIELD: The annual rate of return on an investment, expressed as a percentage.

FINANCIAL STATEMENTS

May 31, 2000 (Unaudited)

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen High Yield Municipal Fund (the "Fund") is organized as a series of
the Van Kampen Tax-Exempt Trust, a Delaware business trust, and is registered as
a diversified open-end management investment company under the Investment
Company Act of 1940, as amended. The Fund's investment objective is to seek to
provide investors with as high a level of interest income exempt from federal
income tax as is consistent with the investing policies of the Fund. The Fund's
investment advisor generally seeks to achieve the Fund's investment objective by
investing primarily in a portfolio of medium- and lower-grade municipal
securities. The Fund commenced investment operations on January 2, 1986. The
distribution of the Fund's Class B and Class C shares commenced on July 20, 1992
and December 10, 1993, respectively.

    The following is a summary of significant accounting policies consistently
followed by the Fund in the preparation of its financial statements. 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 revenues and expenses during the reporting period.
Actual results could differ from those estimates.

A. SECURITY VALUATION Municipal bonds are valued by independent pricing services
or dealers using the mean of the bid and asked prices or, in the absence of
market quotations, at fair value based upon yield data relating to municipal
bonds with similar characteristics and general market conditions. Securities
which are not valued by independent pricing services are valued at fair value
using procedures established in good faith by the Board of Trustees. Short-term
securities with remaining maturities of 60 days or less are valued at amortized
cost, which approximates market value.

    The Fund's investments include lower-rated and unrated debt securities which
may be more susceptible to adverse economic conditions than investment grade
holdings. These securities are often subordinated to the prior claims of other
senior lenders and uncertainties exist as to an issuer's ability to meet
principal and interest payments. Securities rated below investment grade and
comparable unrated securities represented approximately 68% of the Fund's
investment portfolio at the end of the period.

B. SECURITY TRANSACTIONS Security transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis. The
Fund may purchase and sell securities on a "when-issued" or "delayed delivery"
basis,

NOTES TO

with settlement to occur at a later date. The value of the security so purchased
is subject to market fluctuations during this period. The Fund will maintain, in
a segregated account with its custodian, assets having an aggregate value at
least equal to the amount of the when-issued or delayed delivery purchase
commitments until payment is made.

    The Fund may invest in repurchase agreements, which are short-term
investments in which the Fund acquires ownership of a debt security and the
seller agrees to repurchase the security at a future time and specified price.
The Fund may invest independently in repurchase agreements, or transfer
uninvested cash balances into a pooled cash account along with other investment
companies advised by Van Kampen Asset Management Inc. (the "Adviser") or its
affiliates, the daily aggregate of which is invested in repurchase agreements.
Repurchase agreements are fully collateralized by the underlying debt
securities. The Fund will make payment for such securities only upon physical
delivery or evidence of book entry transfer to the account of the custodian
bank. The seller is required to maintain the value of the underlying security at
not less than the repurchase proceeds due the Fund.

C. INCOME AND EXPENSES Interest income is recorded on an accrual basis. Bond
premium is amortized and original issue discount is accreted over the life of
each applicable security. Income and expenses of the Fund are allocated on a pro
rata basis to each class of shares, except for distribution and service fees and
transfer agency costs which are unique to each class of shares.

D. FEDERAL INCOME TAXES It is the Fund's policy to comply with the requirements
of the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no provision for federal income taxes is required.

    The Fund intends to utilize provisions of the federal income tax laws which
allow it to carry a realized capital loss forward for eight years following the
year of the loss and offset these losses against any future realized capital
gains. At November 30, 1999, the Fund had an accumulated capital loss
carryforward for tax purposes of $9,025,107 which expires between November 30,
2003 and November 30, 2005. Net realized gains or losses differ for financial
reporting and tax purposes primarily as a result of the deferral of losses
relating to wash sale transactions.

    At May 31, 2000, for federal income tax purposes, cost of long- and
short-term investments is $1,492,447,386; the aggregate gross unrealized
appreciation is $18,659,998 and the aggregate gross unrealized depreciation is
$97,509,332, resulting in net unrealized depreciation on long- and short-term
investments of $78,849,334.

E. DISTRIBUTION OF INCOME AND GAINS The Fund declares daily and pays monthly
dividends from net investment income. Net realized gains, if any, are
distributed annually.

    Due to inherent differences in the recognition of expenses under generally
accepted accounting principles and federal income tax purposes, the amount of
distributed net investment income may differ for a particular period. These
differences are temporary in nature, but may result in book basis distribution
in excess of net investment income for certain periods.

2. INVESTMENT ADVISORY AGREEMENT AND
OTHER TRANSACTIONS WITH AFFILIATES

Under the terms of the Fund's Investment Advisory Agreement, the Adviser and Van
Kampen Advisors Inc. (the "Subadvisers") will provide investment advice and
facilities to the Fund for an annual fee payable monthly as follows:

    For the six months ended May 31, 2000, the Fund recognized expenses of
approximately $22,000 representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom (Illinois), counsel to the Fund, of which a trustee of the
Fund is an affiliated person.

    For the six months ended May 31, 2000, the Fund recognized expenses of
approximately $41,500 representing Van Kampen Funds Inc. or its affiliates'
(collectively "Van Kampen") cost of providing accounting services to the Fund.

    Van Kampen Investor Services Inc., an affiliate of the Adviser, serves as
the shareholder servicing agent for the Fund. For the six months ended May 31,
2000, the Fund recognized expenses of approximately $329,400. Transfer agency
fees are determined through negotiations with the Fund's Board of Trustees and
are based on competitive market benchmarks.

    Certain officers and trustees of the Fund are also officers and directors of
Van Kampen. The Fund does not compensate its officers or trustees who are
officers of Van Kampen.

    The Fund provides deferred compensation and retirement plans for its
trustees who are not officers of Van Kampen. Under the deferred compensation
plan, trustees may elect to defer all or a portion of their compensation to a
later date. Benefits under the retirement plan are payable for a ten-year period
and are

approximately $78,000 and CDSC on the redeemed shares of Classes B and C of
approximately $504,600. Sales charges do not represent expenses of the Fund.

4. INVESTMENT TRANSACTIONS

During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $107,104,675 and $152,945,846,
respectively.

5. DERIVATIVE FINANCIAL INSTRUMENTS

A derivative financial instrument in very general terms refers to a security
whose value is "derived" from the value of an underlying asset, reference rate
or index.

    The Fund has a variety of reasons to use derivative instruments, such as to
attempt to protect the Fund against possible changes in the market value of its
portfolio and to manage the portfolio's effective yield, maturity and duration.
All of the Fund's portfolio holdings, including derivative instruments, are
marked to market each day with the change in value reflected in the unrealized
appreciation/depreciation. Upon disposition, a realized gain or loss is
recognized accordingly, except when taking delivery of a security underlying a
futures contract. In this instance the recognition of gain or loss is postponed
until the disposal of the security underlying the futures contract.

    The Fund may invest in future contracts, a type of derivative. A futures
contract is an agreement involving the delivery of a particular asset on a
specified future date at an agreed upon price. The Fund generally invests in
futures on U.S. Treasury Bonds and the Municipal Bond Index and typically closes
the contract

                                       64
<PAGE>   66

NOTES TO
FINANCIAL STATEMENTS

May 31, 2000 (Unaudited)

prior to the delivery date. These contracts are generally used to manage the
portfolio's effective maturity and duration.

    Upon entering into future contracts, the Fund maintains, in a segregated
account with its custodian, cash or liquid securities with a value equal to its
obligation under the futures contracts. During the period the futures contract
is open, payments are received from or made to the broker based upon changes in
the value of the contract (the variation margin).

    There were no transactions in futures contracts during the period ended May
31, 2000.

6. DISTRIBUTION AND SERVICE PLANS

The Fund and its shareholders have adopted a distribution plan pursuant to Rule
12b-1 under the Investment Company Act of 1940, as amended, and a service plan
(collectively the "Plans"). The Plans govern payments for the distribution of
the Fund's shares, ongoing shareholder services and maintenance of shareholder
accounts.

    Annual fees under the Plans of up to .25% for Class A net assets and 1.00%
each for Class B and Class C net assets are accrued daily. Included in these
fees for the six months ended May 31, 2000, are payments retained by Van Kampen
of approximately $1,437,700.

7. BORROWINGS

In accordance with its investment policies, the Fund may borrow from banks for
temporary purposes and is subject to certain other customary restrictions.
Effective November 30, 1999, the Fund, in conjunction with certain other funds
of Van Kampen, has entered in to a $650,000,000 committed line of credit
facility with a group of banks which expires on November 28, 2000, but is
renewable with the consent of the participating banks. Each Fund is permitted to
utilize the facility in accordance with the restrictions of its prospectus. In
the event the demand for the credit facility meets or exceeds $650 million on a
complex-wide basis, each Fund will be limited to its pro-rata percentage based
on the net assets of each participating fund. Interest on borrowings is charged
under the agreement at a rate of 0.50% above the federal funds rate per annum.
An annual commitment fee of 0.09% per annum is charged on the unused portion of
the credit facility, which each fund incurs based on its pro-rate percentage of
quarterly net assets. The Fund has not borrowed against the credit facility
during the period.
