                             LETTER TO SHAREHOLDERS

December 20, 1999

Dear Shareholder,

    As we approach the end of the century--and the millennium--it seems
appropriate to take a look back at the progress that's been made over the last
100 years and how the world of investing has changed over the generations.
Although rapid advances in technology and science have dramatically altered the
world that we live in today, one of the greatest shifts we've seen this century
is the increasing importance of investing for many Americans.

    Once considered primarily for the wealthy, investing in the stock market is
now available to most people. In fact, almost 79 million individuals--who
represent almost half of all U.S. households--own stocks either directly or
through mutual funds. This is even more impressive when considering that just 16
years earlier, only 19 percent of households owned stocks. Another important
shift has been the need for retirement planning beyond a pension plan or Social
Security. The Investment Company Institute, the leading mutual fund industry
association, reports that 77 percent of all mutual fund shareholders earmarked
retirement as their primary financial goal in 1998.

    Through all the changes in the investment environment over the past century,
the general principles that have made generations of investors successful remain
the same. Those that have stood the test of time include:
          - Investing for the long-term
          - Basing investment decisions on sound research
          - Building a diversified portfolio
          - Believing in the value of professional investment advice

    While no one can predict the future, at Van Kampen, we believe that these
ideas will remain important tenets for investors well into the next century. As
we continue to focus on these principles, we hope that our decades of investment
experience can help bring you closer to your financial goals as we enter the new
millennium.

Sincerely,


[SIG]

                               ECONOMIC SNAPSHOT

ECONOMIC GROWTH

    Americans continued their spending spree, keeping the economy growing at a
brisk pace. High levels of consumer confidence fueled this heavy retail
activity, which pushed the personal savings rate to a record low in September as
spending rates outpaced income growth. Although the U.S. economy experienced a
slowdown during the second quarter of 1999, growth rebounded in the third
quarter with gross domestic product increasing an annualized 5.7 percent.

EMPLOYMENT

    The strong job market helped support the strength of the economy. During the
reporting period, the unemployment rate reached its lowest level in almost 30
years, and wages continued to climb. Wage pressures pushed the cost of labor
higher in the second quarter, as the employment cost index (ECI) recorded its
biggest gain in eight years. However, productivity gains offset rising wages in
the third quarter, bringing the ECI back to a more moderate level.

INFLATION AND INTEREST RATES

    Although the Consumer Price Index continued to reflect historically low
inflation, concerns about future increases in inflation were prevalent
throughout the reporting period. The Federal Reserve Board remained active in
guarding against inflation and tempering economic growth. The Fed reversed its
three interest-rate cuts from the fall of 1998 by raising rates in June, August,
and November 1999 in an attempt to keep the economy from overheating.

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 A shares) or contingent deferred
sales charge for early withdrawal (4% for B shares and 1% for C shares). If the
sales charge was included, total return would be lower.

(2)Standardized total return. Assumes reinvestment of all distributions for the
period and includes payment of the maximum sales charge (A shares) or contingent
deferred sales charge for early withdrawal (B shares and C shares).

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

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

(5)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 November 30, 1999.

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

See the Comparative Performance section of the current prospectus. Past
performance does not guarantee future results. Investment return and net asset
value will fluctuate with market conditions. Fund shares, when redeemed, may be
worth more or less than their original cost.

Investing in high-yield, lower rated securities involves certain risks, which
may include the potential for greater sensitivity to general economic downturns
and greater market price volatility.

                 PUTTING YOUR FUND'S PERFORMANCE IN PERSPECTIVE

    As you evaluate your progress toward achieving your financial goals, it is
important to track your investment performance at regular intervals. A
comparison of your Fund's performance to an applicable benchmark can:

    - Illustrate the market environment in which your Fund is being managed.

    - Reflect the impact of favorable market trends or difficult market
      conditions.

    - Help you evaluate how your Fund's investment adviser has responded to
      opportunities and challenges.

    The following graph compares your Fund's performance to that of the Lehman
Brothers Municipal Bond Index over time. The index is a broad-based, statistical
composite that does not include any commissions or sales charges that would be
paid by an investor purchasing the securities it represents.

The above chart reflects the performance of Class A shares of the Fund. The
performance of Class A shares will differ from that of other share classes of
the Fund because of the difference in sales charges and/or expenses paid by
shareholders investing in the different share classes. The Fund's performance
assumes reinvestment of all distributions, and includes payment of the maximum
sales charge (4.75% for A shares).

While past performance is not indicative of future performance, the above
information provides a broader vantage point from which to evaluate the

                          PORTFOLIO MANAGEMENT REVIEW

                      VAN KAMPEN HIGH YIELD MUNICIPAL FUND

We recently spoke with representatives of the adviser of the Van Kampen High
Yield Municipal Fund about the key events and economic forces that shaped the
markets during the past 12 months. The representatives are led by Wayne D.
Godlin, portfolio manager, who has managed the Fund since March 1990 and has
worked in the investment industry since 1984.

    Mr. Godlin is joined by Peter W. Hegel, chief investment officer for
fixed-income investments. The following discussion reflects their views on the
Fund's performance during the 12-month period ended November 30, 1999.

   Q  HOW WOULD YOU DESCRIBE THE MARKET ENVIRONMENT IN WHICH THE FUND HAS
      OPERATED DURING THE PAST 12 MONTHS?

   A  Overall, the past 12 months were terrible for both taxable and tax-exempt
      bond markets as long-term U.S. interest rates rose by nearly one percent.
      When long-term interest rates rise, bond prices go down, making this a
difficult environment for bond funds to achieve favorable returns. Generally,
municipal bonds--the type of bonds the Fund invests in--underperformed taxable
bonds during the reporting period.

    The tight credit spread between high- and low-quality bonds was the story of
the first six months of the period--with interest rates paid on low-quality
bonds not much higher than those paid on higher-quality bonds. When this
happens, the lower-quality, higher yielding municipal bonds that we prefer
become less attractive for investors, who can get comparable yields from
higher-quality bonds, which bring less risk. During the remainder of the period,
we saw credit spreads become wider as interest rates rose. For the year, the
supply of high-yield municipal bonds increased compared to 1998, particularly in
the new issue or primary market.

   Q  HOW DID YOU POSITION THE FUND IN THIS ENVIRONMENT?

   A  We evaluate municipal bonds on an individual basis--regardless of whether
      credit spreads are tight or wide--and we continued to position the Fund
      for the long term. To do so, we seek to maintain a highly diversified
portfolio, by geography and sector, which is an important strategy when
investing in high-yield, high-risk municipal bonds. Diversity allows us to help
reduce the effects of weakness in a specific municipality or economic sector.
Our research team of seven analysts--located throughout the country--focused on
uncovering value in small to mid-size new issues, particularly among
higher-yielding nonrated bonds. Despite poor performance among municipal bond
funds, we believe it was our strategy that helped the Fund outperform its peers.

   Q  DISCUSS THE FUND'S PERFORMANCE COMPARED TO THAT OF ITS PEERS.

   A  We were pleased with the Fund's favorable performance compared to its
      peers. We typically have maintained a greater percentage of assets in
      higher-yielding, lower-rated securities than other funds in our peer
group, which has historically helped us outpace our peer average. The Fund's
performance earned an overall rating of five stars from Morningstar in the
Municipal Bond Fund Category, which means it ranked in the top 10 percent of
funds within its category. The Fund's Class A shares received five stars in each
of the three-, five-, and ten-year periods, which were calculated among 1610,
1330, and 383 funds in the municipal bond fund category, respectively, as of
November 30, 1999.

    Morningstar is an independent rating company and the five-star composite
rating is the highest rating it assigns in its monthly mutual fund reviews.*
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.

   Q  WHAT PERCENTAGE OF THE FUND IS INVESTED IN NONRATED BONDS AND WHY?

   A  As of November 30, 1999, 83.0 percent of the Fund was invested in nonrated
      bonds. We prefer to invest in nonrated bonds because we believe there has
      been a significant improvement in the overall credit quality of these
types of bonds in a broad range of sectors. As a result of this strategy, the
Fund benefited from significant improvements in the credit quality of our
holdings, which counteracted the effects of weakness in the overall municipal
bond market.

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

   A  Generally, we look for opportunities to invest in bonds that typically
      have had low sensitivity to changes in the economy--such as health care
      and low- to moderate-income housing. We believe these sectors will
cultivate demand in a strong or weak economy.

    Although the Fund's sector weightings reflect where we found opportunity on
a bond-by-bond basis, we did benefit from purchases in life-care projects and
utility district deals. One disappointment that hurt the Fund's performance was
our exposure to pollution control revenue bonds in the steel industry. For
additional Fund portfolio highlights, please refer to page 9.

   Q  HOW DO YOU FEEL ABOUT THE FUND'S PERFORMANCE DURING THE PAST 12 MONTHS?

   A  Strictly speaking, the Fund's performance was disappointing. Considering
      the poor market conditions we faced during the period, however, we are
      pleased with the Fund's performance compared to its benchmark, the Lehman
Brothers Municipal Bond Index. The total return for the 12 months ended November
30, 1999, was -0.37 percent(1) (Class A

                                        6
<PAGE>   8

shares at net asset value), and the Fund's net asset value closed the reporting
period at $10.96 per Class A share, down from $11.66 at the beginning of the
period. The Fund's Class A share tax-exempt distribution rate as of November 30,
1999, was 5.84 percent(3), representing a taxable equivalent distribution rate
of 9.13 percent(4) for an investor in the 36-percent federal income tax bracket.

    Our total return record continues to outpace the Lehman Brothers Municipal
Bond Index, which returned -1.07 percent during the same 12-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 or
investments it represents. Please refer to the footnotes and chart on page 3 for
additional Fund performance results. Past performance does not guarantee future
results.

   Q  WHAT OTHER FACTORS HAVE ADDED TO THE FUND'S LONG-TERM SUCCESS?

   A  We believe our strengths, particularly in primary market research, have
      helped the Fund's performance. For the second consecutive year, one of our
      analysts was recognized for research capabilities in the latest Smith's
Research & Ratings Review analyst survey. This industry publication surveys
1,000 of the largest institutional investors in order to recognize the
industry's top bond analysts. Historically, the Fund has had particularly strong
performance in health-care related issues. Therefore, it comes as no surprise
that our award-winning analyst specializes in the tax-exempt health-care sector.

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

   A  Overall, we expect a more positive environment for municipal bonds, but we
      don't plan to change our investment approach. We will continue to focus on
      our strengths: doing 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 achieve
its investment objective--providing shareholders with a high level of interest
income exempt from federal income tax.

* The five-star rating is a composite rating. Morningstar is an independent
  mutual fund performance monitor. Morningstar proprietary ratings reflect
  historical risk-adjusted performance as of November 30, 1999. The ratings are
  subject to change every month. Past performance is no guarantee of future
  results. Morningstar ratings are calculated from the fund's three-, five-, and
  ten-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. Ratings are for Class A shares
  and may vary for other class shares.

                               GLOSSARY OF TERMS

CLASS A SHARES: When Class A shares of a fund are purchased, the share price
    includes the net asset value plus a one-time sales charge (or "load"). In
    most cases, there is 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 form
    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.

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.

PRIMARY MARKET: The dealer-conducted process of buying new issues from local
    municipalities and selling them to the public.

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

                         NOTES TO FINANCIAL STATEMENTS

                               November 30, 1999
- --------------------------------------------------------------------------------

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 as high a level of interest income exempt from federal income tax as is
consistent with investing in medium- to lower-rated high yielding 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.
    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 67% 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, with settlement to occur at a later date. The value of the security so
purchased is subject to

                                       58

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

                               November 30, 1999
- --------------------------------------------------------------------------------

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 and original issue discount are amortized 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 November 30, 1999, for federal income tax purposes, cost of long- and
short-term investments is $1,505,466,558; the aggregate gross unrealized
appreciation is

$36,184,193 and the aggregate gross unrealized depreciation is $56,372,274,
resulting in net unrealized depreciation of $20,188,081.

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 will
provide investment advice and facilities to the Fund for an annual fee payable
monthly as follows:

1999, the Fund recognized expenses of approximately $675,600. Transfer agency
fees are determined through negotiations with the Fund's Board of Trustees and
are based on competitive market benchmarks.

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 based upon each trustee's years of service to the Fund. The maximum
annual benefit per trustee under the plan is $2,500.

4. INVESTMENT TRANSACTIONS
During the period, the cost of purchases and proceeds from sales of investments,
excluding short-term investments, were $464,105,455 and $325,638,418,
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.
    During the period the Fund invested 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 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).
    Transactions in futures contracts, each with a par value of $100,000, for
the year ended November 30, 1999, were as follows:

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 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 year ended November 30, 1999, are payments retained by Van Kampen
of approximately $3,328,300.

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 made no borrowings on November 30, 1999. The Fund
has not borrowed against the credit facility during the period.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Shareholders and Board of Trustees of
Van Kampen High Yield Municipal Fund

In our opinion, the accompanying statement of assets and liabilities, including
the portfolio of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Van Kampen High Yield Municipal
Fund (the "Fund"), a series of the Van Kampen Tax-Exempt Trust, at November 30,
1999, and the results of its operations, the changes in its net assets and the
financial highlights for each of the periods presented, in conformity with
accounting principles generally accepted in the United States. These financial
statements and financial highlights (hereafter referred to as "financial
statements") are the responsibility of the Fund's management; our responsibility
is to express an opinion on these financial statements based on our audits. We
conducted our audits of these financial statements in accordance with auditing
standards generally accepted in the United States, which require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits, which included confirmation of securities at
November 30, 1999 by correspondence with the custodian and brokers, provide a
reasonable basis for the opinion expressed above.
