 OVERVIEW

LETTER TO SHAREHOLDERS
February 20, 2000

Dear Shareholder,

As we enter a new century--and 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 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. Some 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 this 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 welcome the
new millennium.

Sincerely,

ECONOMIC SNAPSHOT

ECONOMIC GROWTH REMAINED VIBRANT IN THE SECOND HALF OF 1999, DUE TO STRONG
CONSUMER SPENDING, INVENTORY BUILD-UP, AND EXPORTS. GROSS DOMESTIC PRODUCT
(GDP), THE PRIMARY MEASURE OF ECONOMIC GROWTH, INCREASED AT HISTORICALLY HIGH
ANNUALIZED RATES OF 5.7 PERCENT AND 6.9 PERCENT, RESPECTIVELY, IN THE LAST TWO
QUARTERS OF THE YEAR. WITH GDP MEASURING 4.1 PERCENT FOR 1999, THIS WAS THE
THIRD SUCCESSIVE YEAR IN WHICH GDP EXCEEDED 4 PERCENT. THE CLOSE OF THE
REPORTING PERIOD ALSO MARKED 107 CONSECUTIVE MONTHS OF ECONOMIC EXPANSION--THE
LONGEST STREAK IN U.S. HISTORY.

STRONG GDP DATA, AMONG OTHER FACTORS, PROMPTED THE FEDERAL RESERVE BOARD TO TAKE
AN ACTIVE STANCE IN TEMPERING ECONOMIC GROWTH AND WARDING OFF INFLATION.
ALTHOUGH THE CONSUMER PRICE INDEX (CPI) ROSE A MODEST 2.7 PERCENT DURING 1999,
THE FED INCREASED THE FEDERAL FUNDS RATE BY 0.25 PERCENT IN AUGUST AND NOVEMBER
1999 AND IN FEBRUARY 2000. FED POLICYMAKERS SUGGESTED THAT ADDITIONAL INCREASES
ARE LIKELY IN THE COMING MONTHS.

ALTHOUGH THE CPI REMAINED QUIET, HINTS OF INFLATION WERE PRESENT IN OTHER
ECONOMIC MEASURES SUCH AS THE EMPLOYMENT COST INDEX (ECI) AND CONSUMER SPENDING
RATES. THE JOB MARKET CONTINUED TO THRIVE AS UNEMPLOYMENT DROPPED TO ITS LOWEST
LEVEL IN 30 YEARS. CONSEQUENTLY, AT YEAR-END THE ECI RECORDED ITS SHARPEST
QUARTER-TO-QUARTER INCREASE SINCE 1991, AS EMPLOYERS WERE FORCED TO INCREASE
BENEFITS SUCH AS HEALTH INSURANCE AND PAID LEAVE TO ATTRACT WORKERS.

THE PROSPECT OF RISING INTEREST RATES APPEARED TO HAVE LITTLE IMPACT ON CONSUMER
SPENDING AND OPTIMISM. CONSUMERS SPENT FREELY IN THE LAST MONTHS OF 1999, WHICH
CULMINATED IN THE STRONGEST HOLIDAY SALES SINCE 1992. AND, THANKS TO PLENTIFUL
JOBS, LOW INFLATION, AND THE REJUVENATED STOCK MARKET, CONSUMER CONFIDENCE
REACHED AN ALL-TIME HIGH IN JANUARY.

Q&A WITH YOUR PORTFOLIO MANAGERS

WE RECENTLY SPOKE WITH REPRESENTATIVES OF THE ADVISER OF THE VAN KAMPEN SENIOR
FLOATING RATE FUND ABOUT THE KEY EVENTS AND ECONOMIC FORCES THAT SHAPED THE
MARKETS DURING THE PAST SIX MONTHS. ONE OF THE KEY EVENTS DURING THE PERIOD WAS
A CHANGE IN PORTFOLIO MANAGERS. ON DECEMBER 8, 1999, HOWARD TIFFEN ASSUMED
DAY-TO-DAY MANAGEMENT RESPONSIBILITIES FOR THE FUND. HE BRINGS MORE THAN 30
YEARS OF GLOBAL AND DOMESTIC INVESTMENT EXPERIENCE TO VAN KAMPEN'S SENIOR LOAN
TEAM.
    THE FOLLOWING DISCUSSION REFLECTS HIS VIEWS ON THE FUND'S PERFORMANCE DURING
THE SIX MONTHS ENDED JANUARY 31, 2000.

Q   CAN YOU TALK ABOUT MARKET
    CONDITIONS DURING THE LAST SIX MONTHS?

A   The last six months could be
described as a game of two halves in the senior loan market. In the summer and
fall of 1999, the supply of loans in the senior loan market was extremely
favorable to investors, providing many new loans with relatively favorable yield
and credit terms. The winter months of 1999 and early 2000 were the reverse,
with sparse offerings and lower relative yields, making it a more difficult
environment for investors.

    Credit deterioration, however, had a much larger impact on investors than
did the supply of senior loans. Defaults reached levels not seen since 1992, and
that was unusual and unexpected by us given the strength of the economy.

Q   HOW DID THESE CONDITIONS AFFECT
    THE FUND, AND WHAT OTHER FACTORS HAD A SIGNIFICANT IMPACT ON THE FUND'S
    PERFORMANCE?

A   The rise in defaults hurt the
entire senior loan industry during the six-month period. Much of the Fund's
loss, approximately 2.6 percent of NAV, was due to its concentration in Iridium
Operating LLC, a telecommunications firm in bankruptcy, and the Fund's modest
holdings in the health-care industry.

    Iridium Operating LLC filed for Chapter 11 bankruptcy protection during the
period, shortly after defaulting on $1.55 billion in bank loans. The company's
primary business relied on building a global satellite network to provide
cellular phone access almost anywhere in the world.

                                        6
<PAGE>   8

Demand for the relatively large and expensive phones fell short of expectations,
and revenues failed to cover debt expenses. The value of these loans were marked
down considerably during the period as new information became available.

    With respect to health care, or to be more precise, nursing homes, we first
mentioned this situation in your last report dated July 31, 1999. At that time,
it was clear that the Balanced Budget Act of 1997 was having more of a negative
effect on nursing homes than initially expected. One component of the act
changed how nursing homes are reimbursed by Medicare. The new policy was
originally projected to save Medicare $8 billion in nursing-home costs over a
five-year period. In 1999, it was discovered that the savings had been
underestimated by nearly half, and that Medicare's new policy would realize
savings of approximately $17 billion over the same period--a difference of $9
billion--siphoned out of nursing-home revenues.

    For many nursing homes, most of which rely on Medicare for about 60 percent
of their revenues, this result put a significant strain on their businesses. As
of January 31, 2000, three of the seven largest providers of long-term care
facilities were operating under bankruptcy protection. [Editor's note: As of
February 20, 2000, four of the seven largest providers were operating under
bankruptcy protection.]

    During 1999, Congress amended the Act to provide some relief from these
negative effects on nursing-home providers. The Balanced Budget Refinement Act
of 1999 revised again the Medicare reimbursement policy to reduce the burden on
the nursing-home sector by approximately $3 billion over the next 5 years, and
this should relieve some of the stress that has been placed on these businesses.

    It was Iridium Operating LLC and, to a lesser extent, the health-care sector
that had the largest adverse impact on the NAV. The Fund's NAV fell from $10.09
on July 31, 1999, to $9.83 as of January 31, 2000.

Q   WHY DID DEFAULTS AFFECT THE
    FUND? AREN'T THE LOANS BACKED BY COLLATERAL?

A   Defaults affect all holders of
interests in senior loans, even those that are collateralized. At least 80
percent of the Fund's loans are required to be "collateralized"--backed by the
borrowers' assets. As a result, the Fund is likely to recover more of its
investment in a defaulted senior loan than it would if it were invested in other
types of securities. Recovery on defaulted senior loans, however, takes time.
When a senior loan defaults (i.e., the borrower is unable to make a scheduled
payment of interest or principal), lenders typically engage in negotiations with
the borrower and, in many cases, other participants in the borrower's capital
structure, to seek to recover the value of the loans. This usually takes the
form of an out-of-court restructuring or bankruptcy proceeding, either of which
can last for several years. During this period, the value of the defaulted
senior loan may decrease, which may result in a decline in the Fund's NAV.

                                        7
<PAGE>   9

    If the borrower is unable to get back on its feet during that period, its
assets would typically be sold, if possible, and the creditors--including the
Fund--are then paid out of the proceeds. However, even in the case of
collateralized senior loans, there is no certainty that the sale of the
collateral will be sufficient to repay all or part of the loan or that the
collateral can or will be sold.

    A July 1999 report by rating agency Moody's Investor Services Inc.
summarized the advantages of senior loans in bankruptcy situations. The report
found that, in the event of a bankruptcy, the median recovery for senior secured
and senior unsecured obligations, such as those held by the Fund, was
significantly higher than it was for other investments such as senior
subordinated debt, subordinated debt (such as bonds), and preferred and common
stock.

    Although this Moody's report may not be indicative of future recoveries for
defaulted senior loans in general or those held in the Fund, it lends support to
our view that long-term investors in senior loans have historically recovered
more of their investments following bankruptcies than have investors in other
securities because of the loan's senior position in a borrower's capital
structure--demonstrating one of the principal benefits of this asset class.

Q   THE FEDERAL RESERVE RAISED
    INTEREST RATES SEVERAL TIMES DURING THE PERIOD. HOW DID THIS AFFECT THE
    FUND?

A   Senior loans are one of the few
fixed-income asset classes with the potential to benefit from rising interest
rates, demonstrating another advantage of this asset class. Interest rates on
senior loans are reset periodically to reflect trends in prevailing short-term
interest rates, such as the Prime Rate and London InterBank Offered Rate. In
January, the Fund raised its dividend from $0.0575 to $0.061 per share. Of
course, while the loans have the ability to pay investors higher yields when
interest rates rise, they also can pay lower rates when interest rates fall.

    Shareholders often ask, "If borrowers are required to pay higher yields to
investors when interest rates rise, doesn't the risk of default increase with
their higher debt costs?" The answer is typically no, at least not directly.
Borrowers are often required to purchase interest-rate insurance from a
third-party bank or insurer. The insurance does not guarantee the solvency of
the borrower, but, subject to the insurer's financial condition, it protects
borrowers from the rising interest cost of their senior loan in rising
interest-rate environments by paying the excess interest cost over a contractual
interest cost cap.

Q   VAN KAMPEN RECENTLY ANNOUNCED
    THAT IT BEGAN MAKING GREATER USE OF INDEPENDENT MARKET INDICATORS PROVIDED
    BY LOAN PRICING CORPORATION (LPC), AN INDEPENDENT PRICING SERVICE, IN
    VALUING CERTAIN OF THE SENIOR LOANS IN THE FUND'S PORTFOLIO. WHAT IMPACT
    MIGHT THIS HAVE ON THE PERFORMANCE?

A   Making greater use of market
indicators, which was implemented on January 26, 2000, has had an insignificant
impact on the NAV of the Fund. The Fund's use of market indicators in valuing
senior loans is not new; we've used these indicators as a factor in valuing
senior loans throughout the life of the Fund, as set forth in the Fund's
disclosure documents. As of January 31, 2000, approximately 37 percent of the
Fund's senior loan assets were priced based on market indicators provided by
LPC.

    As stated in the Fund's disclosure documents, the NAV of the Fund will
fluctuate as a function of interest rate and credit factors. Moreover, the
Fund's greater use of independent market indicators in valuing certain senior
loans has no affect on the yield of the Fund. Yield is determined based upon the
income earned on assets held in the Fund.

    The Fund will continue to value senior loans for which reliable market
indicators are not available in a manner consistent with the Board of Trustees'
long-standing fair value methodology and with pricing policies governed by
procedures adopted by the Board.

Q   TO SUMMARIZE, HOW DID THE
    FUND PERFORM DURING THE REPORTING PERIOD?

A   The Fund's total return for the six-
month period was 1.02 percent at NAV. Based on the January 25, 2000, public
offering price of $9.90 per share, the Fund's current monthly dividend of $0.061
represents a distribution rate of 7.39 percent. For more information on the
Fund's performance, please refer to the chart and footnotes on page 3. Also,
please remember that past performance does not guarantee future results.

Q   WHAT IS YOUR OUTLOOK FOR THE
    SENIOR LOAN MARKET AND FOR THE FUND?

A   We believe the outlook for the
senior loan market is very good, particularly when compared to our outlook six
months ago. In the primary or "new loans" market, we've seen a large number of
mergers and acquisitions (M&A) in recent months. M&A activity often leads to an
increase in new senior loans coming to market, as many companies use senior
loans to help finance these activities. We believe this may lead to an abundance
of offerings with strong credit protection and higher relative yields. In the
developing secondary market, we believe there may be growing opportunities for
the Fund to acquire senior loans from other investors at prices lower than and
at yields higher than we could expect to receive in the primary or new loans
markets.

                                        9
<PAGE>   11

    In terms of credit quality, we believe the rate of defaults during 2000 may
be lower than in 1999. We anticipate that defaults during 2000 may fall to
approximately 2 to 3 percent from 7.5 percent during 1999. The principal reason
for our optimism is that we believe the negative effects of the Balanced Budget
Act of 1997 on the health-care sector were reflected primarily during 1999 and
that most of the defaults by nursing-home providers have already occurred. Of
course, there can be no assurance that our forecast will be accurate, but we are
hopeful the industry-wide problem that occurred in the health-care sector is
behind us.

    As the Fed raises interest rates, we may also see a rise in investors'
demand for senior loan funds, as investors seek to take advantage of one of the
few asset classes with the potential to benefit from rising interest rates and
inflation.

    With regard to the Fund, our goal is to further diversify the loans we hold.

average of nearly 15 years of experience, we believe that we have the resources
to manage a significantly larger number of loans than we currently hold. In the
long run, we believe that improved diversification will add strength and
stability to the Fund's NAV and dividends.

GLOSSARY OF TERMS

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

FEDERAL RESERVE BOARD (THE FED): The governing body of the Federal Reserve
System, which is the central bank of the United States. Its policy-making
committee, called the Federal Open Market Committee, meets eight times a year to
establish monetary policy and monitor the economic pulse of the United States.

FUNDAMENTALS: Characteristics of a company, such as revenue growth, earnings
growth, financial strength, market share, and quality of management.

NET ASSET VALUE (NAV): The value of a mutual fund share, calculated by deducting
a fund's liabilities from the total assets in its portfolio and dividing this
amount by the number of shares outstanding. The NAV does not include any initial
or contingent deferred sales charge; if these charges were included, the NAV
would decrease.

SENIOR LOANS: Loans or other debt securities that are given preference to junior
securities of the borrower. In the event of bankruptcy, payments to holders of
senior loan obligations are given priority over payments to shareholders of
subordinated debt, as well as shareholders of preferred and common stock. Senior
loans may share priority status with other senior securities of the borrower,
and such status is not a guarantee that monies to which the Trust is entitled
will be paid.

A FOCUS ON SENIOR LOANS

    The Senior Floating Rate Fund invests primarily in senior collateralized
loans to corporations, partnerships, and other business entities that operate in
a variety of industries and geographic locations. Senior loans have a number of
characteristics that, in the opinion of the Fund's management team, are
important to the integrity of the Fund's portfolio. These include:

SENIOR STANDING

    With respect to interest payments, senior loans generally have priority over
other classes of loans, preferred stock, or common stocks, though they may have
equal status with other securities of the borrower. This status is not a
guarantee, however, that monies to which the Fund is entitled will be paid. If
they are not fully paid, it potentially could have a negative effect on the
Fund's net asset value. For more details, please refer to the prospectus.

COLLATERAL BACKING

    Senior loans are often secured by collateral that has been pledged by the
borrower under the terms of a loan agreement. Forms of collateral include
trademarks, accounts receivable or inventory, buildings, real estate,
franchises, and common and preferred stock in subsidiaries and affiliates. Under
certain circumstances, collateral might not be entirely sufficient to satisfy
the borrower's obligations in the event of non-payment of scheduled interest or
principal, and in some instances may be difficult to liquidate on a timely
basis.

    Additionally, a decline in the value of the collateral could cause the loan
to become substantially undersecured, and circumstances could arise (such as
bankruptcy of a borrower) that could cause the Fund's security interest in the
loan's collateral to be invalidated. This could potentially have a negative
effect on the Fund's net asset value.

CREDIT QUALITY

    Many senior loans carry provisions designed to protect the lender in certain
circumstances. In addition, the variable-rate nature of the portfolio is
expected to lessen the fluctuation in the Fund's net asset value. However, the
net asset value will still be subject to the influence of changes in the real or
perceived credit quality of the loans in which the Fund invests. This may occur,
for example, in the event of a sudden or extreme increase in prevailing interest
rates, a default in a loan in which the Fund holds an interest, or a substantial
deterioration in the borrower's creditworthiness. From time to time, the Fund's
net asset value may be more or less than at the time of the investment.

SPECIAL CONSIDERATIONS

    Under normal market conditions, the Fund may invest up to 20 percent of its
assets in senior loans that are not secured by any specific collateral. In
addition, up to 20 percent of its assets may be invested in senior loans made to
non-U.S. borrowers, although these loans must be U.S.-dollar denominated.

NR=Not Rated

 +  Bank loans rated below Baa by Moody's Investor Service, Inc. or BBB by
    Standard & Poor's Group are considered to be below investment grade.

 1  Industry percentages are calculated as a percentage of net assets.

(a) This Senior Loan interest is non-income producing.

(b) This Borrower has filed for protection in federal bankruptcy court.

 *  Senior Loans in the Fund's portfolio generally are subject to mandatory
    and/or optional prepayment. Because of these mandatory prepayment conditions
    and because there may be significant economic incentives for a Borrower to
    prepay, prepayments of Senior Loans in the Fund's portfolio may occur. As a
    result, the actual remaining maturity of Senior Loans held in the Fund's
    portfolio may be substantially less than the stated maturities shown.
    Although the Fund is unable to accurately estimate the actual remaining
    maturity of individual Senior Loans, the Fund estimates that the actual
    average maturity of the Senior Loans held in its portfolio will be
    approximately 18-24 months.

 **  Senior Loans in which the Fund invests generally pay interest at rates
     which are periodically redetermined by reference to a base lending rate
     plus a premium. These base lending rates are generally (i) the lending rate
     offered by one or more major European banks, such as the London Inter-Bank
     Offered Rate ("LIBOR"), (ii) the prime rate offered by one or more major
     United States banks and (iii) the certificate of deposit rate. Senior loans
     are generally considered to be restricted in that the Fund ordinarily is
     contractually obligated to receive approval from the Agent Bank and/or
     borrower prior to the disposition of a Senior Loan.

1. SIGNIFICANT ACCOUNTING POLICIES

Van Kampen Senior Floating Rate Fund (the "Fund") is registered as a non-
diversified closed-end management investment company under the Investment
Company Act of 1940, as amended. The Fund's investment objective is to provide a
high level of current income, consistent with preservation of capital. The Fund
seeks to achieve its objective by investing primarily in a portfolio of
interests in floating or variable rate senior loans to corporations,
partnerships and other entities which operate in a variety of industries and
geographical regions. The Fund commenced investment operations on March 27,
1998.

    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 The Fund's Variable Rate Senior Loan interests ("Loan
interests") are valued by the Fund following guidelines established and
periodically reviewed by the Fund's Board of Trustees. Subject to criteria
established by the Fund's Board of Trustees about the availability and
reliability of market indicators obtained from independent pricing sources,
certain Loan interests are valued at the mean of bid and ask market indicators
supplied by independent pricing sources approved by the Fund's Board of
Trustees. All other Loan interests are valued by considering a number of factors
including consideration of market indicators, transactions in instruments which
Van Kampen Investment Advisory Corp. (the "Adviser") believes may be comparable
(including comparable credit quality, interest rate, interest rate
redetermination period and maturity), the credit worthiness of the Borrower, the
current interest rate, the period until next interest rate redetermination and
the maturity of such Loan interests. Consideration of comparable instruments may
include commercial paper, negotiable certificates of deposit and short-term
variable rate securities which have adjustment periods comparable to the Loan
interests in the Fund's portfolio. The fair value of Loan interests are reviewed
and approved by the Fund's Valuation Committee and by the Fund's Board of
Trustees. The fair value of a Loan interest may differ significantly from the
market value that would have been used had there been a ready and reliable
market for that Loan interest.

    Short-term securities with remaining maturities of 60 days or less are
valued at amortized cost. Short-term loan participations are valued at cost in
the absence of any indication of impairment.

B. SECURITY TRANSACTIONS Investment transactions are recorded on a trade date
basis. Realized gains and losses are determined on an identified cost basis.

C. INVESTMENT INCOME Interest income is recorded on an accrual basis. Facility
fees received are treated as market discounts. Market premiums and discounts are
amortized over the stated life of each applicable security. Other income is
comprised primarily of amendment fees. Amendment fees are earned as compensation
for agreeing to changes in loan agreements.

D. ORGANIZATIONAL COSTS The Fund has agreed to reimburse Van Kampen Funds Inc.
or its affiliates (collectively "Van Kampen") for costs incurred in connection
with the Fund's organization in the amount of $140,000. These costs normally are
amortized over a 60 month period beginning on the date of the Fund's initial
public offering of its shares. However, AICPA Statement of Position 98-5, which
is effective for fiscal years beginning after December 15, 1998, requires that
unamortized organizational costs on the Fund's statement of assets and
liabilities be written off. Therefore, the Fund wrote off the remaining
unamortized organizational costs in August 1999.

E. 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.

    Net realized gains or losses may differ for financial reporting and tax
purposes primarily as a result of the deferral of losses relating to wash sale
transactions.

    At January 31, 2000, for federal income tax purposes the cost of long- and
short-term investments is $1,725,004,944, the aggregate gross unrealized
appreciation is $7,278,392 and the aggregate gross unrealized depreciation is
$52,828,571 resulting in net unrealized depreciation on long- and short-term
investments of $45,550,179.

F. 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. Distributions from net realized gains for book purposes
may include short-term capital gains, which are included as ordinary income for
tax purposes.

monthly as follows:

Next $2.5 billion...........................................    .875 of 1%
Over $10.0 billion..........................................    .850 of 1%
</TABLE>

    In addition, the Fund will pay a monthly administrative fee to Van Kampen
Funds Inc., the Fund's Administrator, at an annual rate of .25% of the average
net assets of the Fund. The administrative services to be provided by the
Administrator include monitoring the provisions of the loan agreements and any
agreements with respect to participations and assignments, record keeping
responsibilities with respect to interests in Variable Rate Senior Loans in the
Fund's portfolio and providing certain services to the holders of the Fund's
securities.

    For the six months ended January 31, 2000, the Fund recognized expenses of
approximately $115,200 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 January 31, 2000, the Fund recognized expenses of
approximately $9,100 representing Van Kampen's cost of providing legal services
to the Fund.

    Van Kampen Investor Services Inc., an affiliate of the Adviser, serves as
the shareholder servicing agent of the Fund. For the six months ended January
31, 2000, the Fund recognized expenses for their services of approximately
$447,700. 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 based upon each trustee's years of service to the Fund. The maximum
annual benefit per trustee under the plan is $2,500.

investments having an aggregate value at least equal to the amount of unfunded
loan commitments.

    The Fund, along with the Van Kampen Prime Rate Income Trust, has entered
into a revolving credit agreement with a syndicate led by Bank of America for an
aggregate of $500,000,000, which will terminate on June 13, 2000. The proceeds
of any borrowing by the Fund under the revolving credit agreement may only be
used, directly or indirectly, for liquidity purposes in connection with the
consummation of a tender offer by the Fund for its shares. Annual commitment
fees of .09% are charged on the unused portion of the credit line. Borrowings
under this facility will bear interest at either the LIBOR rate or the Federal
Funds rate plus .45%. There have been no borrowings under this agreement to
date.

8. SENIOR LOAN PARTICIPATION COMMITMENTS

The Fund invests primarily in participations, assignments, or acts as a party to
the primary lending syndicate of a Variable Rate Senior Loan interest to
corporations, partnerships, and other entities. When the Fund purchases a
participation of a Senior Loan interest, the Fund typically enters into a
contractual agreement with the lender or other third party selling the
participation, but not with the borrower directly. As such, the Fund assumes the
credit risk of the Borrower, Selling Participant or other persons
interpositioned between the Fund and the Borrower.

    At January 31, 2000, the following sets forth the selling participants with
respect to interests in Senior Loans purchased by the Fund on a participation
basis.
