- --------------------------------------------------------------------------------
                       VAN KAMPEN PRIME RATE INCOME TRUST
- --------------------------------------------------------------------------------
 
    The Van Kampen Prime Rate Income Trust's objective is to provide a high
level of current income, consistent with preservation of capital. The Fund
invests primarily in adjustable rate Senior Loans. Senior Loans are business
loans that have a senior right to payment. They are made to corporations and
other Borrowers and are often secured by specific assets of the Borrower. The
Fund believes that investing in adjustable rate Senior Loans should limit
fluctuations in net asset value caused by changes in interest rates. You should,
however, expect the Fund's net asset value to fluctuate as a result of changes
in Borrower credit quality and other factors.
 
  There is no assurance that the Fund will achieve its investment objective. You
should carefully consider the risks of investing in the Fund. See "Special Risk
Considerations."
 
   
  Pursuant to this Prospectus, the Fund is offering 250,000,000 common shares of
beneficial interest. The Fund's Shares have no trading market and no market is
expected to develop. You should consider your investment in the Fund to be
illiquid. In order to provide Shareholders an opportunity to sell their Shares,
the Fund currently intends to offer to repurchase at net asset value a portion
of its outstanding Shares each quarter. There is no guarantee that you will be
able to sell your Shares at any given time. If you hold your Shares for less
than five years, you will likely be charged an early withdrawal charge at the
time the Fund repurchases your Shares.
    
 
                               ------------------
 
NEITHER THE SECURITIES AND EXCHANGE COMMISSION NOR ANY STATE REGULATOR HAS
APPROVED OR DISAPPROVED OF THE SHARES OR PASSED ON THE ADEQUACY OF THIS
PROSPECTUS. A REPRESENTATION TO THE CONTRARY IS A CRIME.
 
                               ------------------
 
    SHARES ARE NOT DEPOSITS OR OBLIGATIONS OF, AND ARE NOT GUARANTEED OR
ENDORSED BY, ANY BANK OR DEPOSITORY INSTITUTION. SHARES ARE NOT INSURED BY THE
FEDERAL DEPOSIT INSURANCE CORPORATION, THE FEDERAL RESERVE BOARD, OR ANY OTHER
GOVERNMENT AGENCY. SHARES INVOLVE INVESTMENT RISKS, INCLUDING THE POSSIBLE LOSS
OF YOUR INVESTMENT.
 
    The Fund continuously offers its Shares through Van Kampen Funds Inc., as
principal underwriter, and through selected broker-dealers and financial
services firms, at a price per Share equal to net asset value. There is no
initial sales charge or underwriting discount on purchases of Shares. Van Kampen
Funds Inc. will pay the broker-dealers and financial services firms
participating in the continuous offering. The minimum initial investment is
$1,000. The minimum initial investment for tax sheltered retirement plans is
$250.
 
   
    The Fund's investment adviser is Van Kampen Investment Advisory Corp. This
prospectus sets forth the information about the Fund that you should know before
investing. You should keep it for future reference. More information about the
Fund, including a Statement of Additional Information dated May   , 1999, has
been filed with the Securities and Exchange Commission. This information is
available upon written or oral request without charge. The Fund's Statement of
Additional Information is incorporated herein by reference. You may get a copy
of it by calling 1-800-341-2911. A table of contents for the Statement of
Additional Information is on page 29. The SEC maintains a web site at
http://www.sec.gov that contains the Statement of Additional Information,
material incorporated by reference and other information about SEC registrants.

                               PROSPECTUS SUMMARY
- --------------------------------------------------------------------------------
 
  This summary is qualified by reference to the more detailed information
included elsewhere in this Prospectus and in the Statement of Additional
Information.
 
   
  THE FUND.  Van Kampen Prime Rate Income Trust is a non-diversified, closed-end
management investment company. The Fund completed an initial public offering of
its common shares of beneficial interest in October, 1989. Since November, 1989
the Fund has continuously offered its Shares through Van Kampen Funds Inc.
("VKF") as principal underwriter. As of February 28, 1999, the Fund had
805,734,260 Shares outstanding and had net assets of $8,001,641,490.
    
 
  THE OFFERING.  The Fund continuously offers Shares through VKF and through
selected broker-dealers and financial services firms at net asset value. There
is no initial sales charge or underwriting discount on purchases of Shares. VKF
pays the broker-dealers and financial services firms participating in the
continuous offering. The minimum initial investment is $1,000 and minimum
subsequent investment is $100. The minimum initial investment for tax sheltered
retirement plans is $250.
 
  INVESTMENT OBJECTIVE AND POLICIES.  The Fund's investment objective is to
provide a high level of current income, consistent with preservation of capital.
There is no assurance that the Fund will achieve its investment objective. You
should carefully consider the risks of investing in the Fund. See "Special Risk
Considerations."
 
  The Fund plans to invest at least 80% of its total assets in adjustable rate
Senior Loans. Senior Loans are business loans made to Borrowers that may be
corporations, partnerships or other entities. These Borrowers operate in a
variety of industries and geographic regions. The interest rates on Senior Loans
adjust periodically, and the Fund's portfolio of Senior Loans will at all times
have a dollar-weighted average time until the next interest rate adjustment of
90 days or less. The Fund believes that investing in adjustable rate Senior
Loans should limit fluctuations in its net asset value caused by changes in
interest rates.
 
  Senior Loans generally are negotiated between a Borrower and several financial
institution Lenders represented by one or more Lenders acting as agent of all
the Lenders. The Agent is responsible for negotiating the Loan Agreement that
establishes the terms and conditions of the Senior Loan and the rights of the
Borrower and the Lenders. The Fund may act as one of the group of Original
Lenders originating a Senior Loan, may purchase Assignments of portions of
Senior Loans from third parties and may invest in Participations in Senior
Loans. Senior Loans may include certain foreign senior debt that is in the form
of notes and not Loan Agreements.
 
  Senior Loans have the most senior position in a Borrower's capital structure
or share the senior position with other senior debt securities of the Borrower.
This capital structure position generally gives holders of Seniors Loans a
priority claim on some or all of the Borrower's assets in the event of default.
Most of the Fund's Senior Loan investments will be secured by specific assets of
the Borrower. Senior Loans also have contractual terms designed to protect
Lenders. The Fund will only acquire Senior Loans of Borrowers that, in the
Adviser's judgment, can make timely payments on their Senior Loans and that
satisfy other credit standards established by the Adviser. Because of their
protective features, the Fund and the Adviser believe that Senior Loans of
Borrowers that either are experiencing, or are more likely to experience,
financial difficulty may represent attractive investment opportunities.
Investing in Senior Loans does, however, involve investment risk, and some
Borrowers default on their Senior Loan payments. The Fund attempts to manage
these risks through selection of a varied portfolio of Senior Loans and careful
analyses and monitoring of Borrowers. Nevertheless, you should expect that the
Fund's net asset value will fluctuate as a result of changes in the credit
quality of Borrowers and other factors. See "Special Risk
Considerations -- Borrower Credit Risk."
 
   
  Following are some of the Fund's other important investment policies: The Fund
may invest up to 20% of its total assets in Senior Loans that are not secured by
any specific collateral. The Fund may invest up to 20% of its total assets in
Senior Loans made to non-U.S. Borrowers. These Senior Loans must, however, be
U.S. dollar denominated and pay principal and interest in U.S. dollars. The Fund
may invest up to 20% of its total assets in any combination of the following:
(1) warrants, equity securities and junior debt securities in each case that are
acquired in connection with the acquisition, restructuring or disposition of a
Senior Loan, and (2) high quality short-term debt securities.
    
 
  SHARE REPURCHASES.  The Fund currently intends, each quarter, to offer to
repurchase a portion of its outstanding Shares at their then current net asset
value. Each repurchase must be preapproved by the Fund's Board of Trustees. To
date, the Fund has repurchased Shares every quarter since it began operations.
The Fund will impose an early withdrawal charge
 
                                        4
<PAGE>   8
 
payable to VKF on most Shares accepted for repurchase that have been held for
less than five years. There is no assurance that the Fund will in fact offer to
repurchase any of its Shares. If the Fund does offer to repurchase Shares there
is no guarantee that all or any Shares tendered will be purchased. The Fund may
borrow to finance repurchases of Shares. Borrowings entail additional risks.
 
   
  INVESTMENT ADVISER.  Van Kampen Investment Advisory Corp. is the Fund's
investment adviser. The Adviser also serves as investment adviser to Van Kampen
Senior Income Trust, a closed-end investment company listed on the New York
Stock Exchange, and to Van Kampen Senior Floating Rate Fund, a closed-end
investment company engaged in a continuous offering. These funds also invest
primarily in Senior Loans. As of February 28, 1999, the Fund together with these
funds had over $11.5 billion in assets. See "Management of the Fund."
    
 
  ADMINISTRATOR.  Van Kampen Investments Inc. is the Fund's administrator (the
"Administrator"). See "Management of the Fund."
 
  FEES AND EXPENSES.  The Fund will pay the Adviser a fee at an annual rate of
0.95% of the average daily net assets of the Fund. This fee is reduced on assets
in excess of $4 billion. The Fund will pay the Administrator a fee at an annual
rate of 0.25% of the average daily net assets of the Fund. See "Management of
the Fund."
 
  DISTRIBUTIONS.  The Fund plans to make monthly distributions of substantially
all net investment income. Distributions cannot be assured, and the amount of
each distribution is likely to vary. Net realized long-term capital gains, if
any, will be distributed at least annually.
 
  DIVIDEND REINVESTMENT PLAN.  You may elect to have your dividends and capital
gain distributions automatically reinvested in additional Shares purchased from
the Fund at net asset value. If you do not elect to participate in this dividend
reinvestment plan you will receive distributions in cash.
 
SPECIAL RISK CONSIDERATIONS
 
  NO TRADING MARKET FOR SHARES.  The Fund is a closed-end investment company
designed primarily for long-term investors and not as a trading vehicle. The
Fund does not intend to list the Shares for trading on any national securities
exchange. There is no secondary trading market for Shares. An investment in the
Shares is illiquid. If the Fund's Board of Trustees does not authorize the Fund
to repurchase its Shares, you will not be able to sell your Shares. Even if the
Fund does make repurchases, there is no guarantee that you will be able to sell
all of the Shares that you desire to sell.
 
  SENIOR LOANS.  There is less readily available, reliable information about
most Senior Loans than is the case for many other types of securities. In
addition, there is no minimum rating or other independent evaluation of a
Borrower or its securities limiting the Fund's investments, and the Adviser
relies primarily on its own evaluation of Borrower credit quality rather than on
any available independent sources. As a result, the Fund is particularly
dependent on the analytical abilities of the Adviser.
 
  Senior Loans are not listed on any national securities exchange or automated
quotation system and no active trading market exists for many Senior Loans. As a
result, many Senior Loans are illiquid, meaning that the Fund may not be able to
sell them quickly at a fair price. The market for illiquid securities is more
volatile than the market for liquid securities. The market could be disrupted in
the event of an economic downturn or a substantial increase or decrease in
interest rates. Although the Fund believes that investing in adjustable rate
Senior Loans should limit fluctuations in net asset value as a result of changes
in interest rates, extraordinary and sudden changes in interest rates could
disrupt the market for Senior Loans and result in fluctuations in the Fund's net
asset value. However, many Senior Loans are of a large principal amount and are
held by a large number of owners. In the Adviser's opinion, this should enhance
their liquidity. In addition, in recent years the number of institutional
investors purchasing Senior Loans has increased. The risks of illiquidity are
particularly important when the Fund's operations require cash, and may in
certain circumstances require that the Fund borrow to meet short-term cash
requirements. Illiquid securities are also difficult to value. See "Investment
Objective and Policies."
 
  Selling Lenders and other persons positioned between the Fund and the Borrower
will likely conduct their principal business activities in the banking, finance
and financial services industries. The Fund may be more at risk to any single
economic, political or regulatory occurrence affecting such industries.
 
                                        5
<PAGE>   9
 
  BORROWER CREDIT RISK.  Senior Loans, like most other debt obligations, are
subject to the risk of default. Default in the payment of interest or principal
on a Senior Loan will result in a reduction in income to the Fund, a reduction
in the value of the Senior Loan and a potential decrease in the Fund's net asset
value and market value. The risk of default will increase in the event of an
economic downturn or a substantial increase in interest rates.
 
  The Fund may acquire Senior Loans of Borrowers that are experiencing, or are
more likely to experience, financial difficulty, including Senior Loans issued
in highly leveraged transactions. The Fund may even acquire and retain in its
portfolio Senior Loans of Borrowers that have filed for bankruptcy protection.
Because of the protective terms of Senior Loans, the Adviser believes that the
Fund is more likely to recover more of its investment in a defaulted Senior Loan
than would be the case for most other types of defaulted debt securities.
Nevertheless, even in the case of collateralized Senior Loans, there is no
assurance that sale of the collateral would raise enough cash to satisfy the
Borrower's payment obligation or that the collateral can or will be liquidated.
In the case of bankruptcy, liquidation may not occur and the court may not give
Lenders the full benefit of their senior position. Uncollateralized Senior Loans
involve a greater risk of loss.
 
   
  INVESTMENT IN NON-U.S. ISSUERS.  The Fund may invest up to 20% of its total
assets, measured at the time of investment, in U.S. dollar denominated Senior
Loans to Borrowers that are organized or located in countries other than the
United States. Although the Senior Loans will require payment of interest and
principal in U.S. dollars, these Borrowers may have significant non-U.S. dollar
revenues. Investment in non-U.S. issuers involves special risks, including that
non-U.S. issuers may be subject to less rigorous accounting and reporting
requirements than U.S. issuers, less rigorous regulatory requirements, differing
legal systems and laws relating to creditors' rights, the potential inability to
enforce legal judgments, fluctuations in currency values and the potential for
political, social and economic adversity.
    
 
  PARTICIPATIONS.  The Fund may purchase Participations in Senior Loans. Under a
Participation the Fund generally will have rights that are more limited than the
rights of Lenders or of persons who acquire a Senior Loan by Assignment. In a
Participation the Fund typically has a contractual relationship with the Lender
selling the Participation, but not with the Borrower. As a result, the Fund
assumes the credit risk of the Lender selling the Participation in addition to
the credit risk of the Borrower. In the event of the insolvency of the Lender
selling the Participation, the Fund may be treated as a general creditor of the
Lender and may not have a senior claim to the Lender's interest in the Senior
Loan.
 
  FUND BORROWINGS.  The Fund is authorized to borrow money in an amount up to
33 1/3% of the Fund's total assets (including the amount borrowed) to finance
repurchases of Shares. The rights of any lenders to the Fund to receive payments
of interest on and repayments of principal of any borrowings will be senior to
the rights of Shareholders. The loan agreement for any borrowing likely will
limit certain activities of the Fund, including the payment of dividends to
holders of Shares in certain circumstances. Interest payments and fees incurred
in connection with borrowings will reduce the amount of net income available for
payment to Shareholders. The Fund will not use borrowings for investment
leverage purposes. Accordingly, the Fund will not purchase additional portfolio
securities at any time that borrowings exceed 5% of the Fund's total assets
(including the amount borrowed). See "Repurchase of Shares."
 
  NON-DIVERSIFIED STATUS. The Fund has registered as a "non-diversified"
investment company. This means that it may invest more than 5% of the value of
its assets in the obligations of any single issuer, including Senior Loans of a
single Borrower and Participations purchased from a single Lender. Although the
Fund does not intend to invest more than 5% of the value of its assets in Senior
Loans of a single Borrower, it may invest more than 5% of its assets in
Participations purchased from a single Lender. If the Fund invests a relatively
high percentage of its assets in obligations of a limited number of issuers, the
Fund will be more at risk to any single corporate, economic, political or
regulatory event that impacts one or more of those issuers.
 
  CERTAIN INVESTMENT PRACTICES.  The Fund may use various investment practices
that involve special risks, including engaging in interest rate and other
hedging and risk management transactions. See "Investment Practices and Special
Risks."

- --------------------------------------------------------------------------------
 
  The Fund's investment objective is to provide a high level of current income,
consistent with preservation of capital. An investment in the Fund may not be
appropriate for all investors and should not be considered a complete investment
program. There is no assurance that the Fund will achieve its investment
objective. You should carefully consider the risks of investing in the Fund. See
"Special Risk Considerations."
 
DESCRIPTION OF SENIOR LOANS
 
  In normal market conditions, the Fund plans to invest at least 80% of its
assets in adjustable rate senior loans ("Senior Loans"). Because Senior Loans
have very large minimum investments, typically $5 million or more, the Fund
provides individual investors access to a market that normally is limited to
institutional investors.
 
  INTEREST RATES AND MATURITY.  Interest rates on Senior Loans adjust
periodically. The interest rates are adjusted based on a base rate plus a
premium or spread over the base rate. The base rate usually is the London
Inter-Bank Offered Rate ("LIBOR"), the prime rate offered by one or more major
United States banks (the "Prime Rate") or the certificate of deposit ("CD") rate
or other base lending rates used by commercial lenders. LIBOR, as provided for
in Loan Agreements, usually is an average of the interest rates quoted by
several designated banks as the rates at which they pay interest to major
depositors in the London interbank market on U.S. dollar denominated deposits.
The Adviser believes that changes in short-term LIBOR rates are closely related
to changes in the Federal Reserve federal funds rate, although the two are not
technically linked. The Prime Rate quoted by a major U.S. bank is generally the
interest rate at which that bank is willing to lend U.S. dollars to is most
creditworthy borrowers, although it may not be the bank's lowest available rate.
The Fund expects that at least 65% of its assets will be invested in Senior
Loans that at the time of investment provided the Borrower with the option of
selecting an interest rate that is based on the Prime Rate. The CD rate, as
provided for in Loan Agreements, usually is the average rate paid on large
certificates of deposit traded in the secondary market.
 
  Interest rates on Senior Loans may adjust daily, monthly, quarterly,
semi-annually or annually. The Fund will not invest more than 5% of its total
assets in Senior Loans with interest rates that adjust less often than
semi-annually. The Fund may use interest rate swaps and other investment
practices to shorten the effective interest rate adjustment period of Senior
Loans. If the Fund does so, it considers the shortened period to be the
adjustment period of the Senior Loan. The Fund's portfolio of Senior Loans will
at all times have a dollar-weighted average time until the next interest rate
adjustment of 90 days or less. As short term interest rates rise, interest
payable to the Fund should increase. As short term interest rates decline,
interest payable to the Fund should decrease. The amount of time that will pass
before the Fund experiences the effects of changing short-term interest rates
will depend on the dollar-weighted average time until the next interest rate
adjustment on the Fund's portfolio of Senior Loans.
 
  When interest rates rise, the values of fixed income securities generally
decline. When interest rates fall, the values of fixed income securities
generally increase. The Fund believes that investing in adjustable rate Senior
Loans should limit fluctuations in the Fund's net asset value caused by changes
in interest rates. The Fund expects the values of its Senior Loan investments to
fluctuate less than the values of fixed rate, longer-term income securities in
response to the changes in interest rates. Changes in interest rates can,
however, cause some fluctuation in the Fund's net asset value.
 
                                        8
<PAGE>   12
 
  The Fund expects that its Senior Loans will have stated maturities ranging
from three to ten years, although the Fund has no policy limiting the maturity
of Senior Loans that it purchases. Senior Loans usually have mandatory and
optional prepayment provisions. Because of prepayments, the actual remaining
maturity of Senior Loans may be considerably less than their stated maturity.
The Fund estimates that the actual maturity of the Senior Loans in its portfolio
will be approximately 18-24 months. Because the interest rates on Senior Loans
adjust periodically, the Fund and the Adviser believe that the reinvestment by
the Fund in Senior Loans after prepayment should not result in a significant
reduction in the interest payable to the Fund. Fees received by the Fund may
even enhance the Fund's income. See " -- The Senior Loan Process," below.
 
  PROTECTIVE PROVISIONS OF SENIOR LOANS.  Senior Loans have the most senior
position in a Borrower's capital structure or share the senior position with
other senior debt securities of the Borrower. This capital structure position
generally gives holders of Senior Loans a priority claim on some or all of the
Borrower's assets in the event of default. Most of the Fund's Senior Loan
investments will be secured by specific assets of the Borrower. These Senior
Loans will frequently be secured by all assets of the Borrower that qualify as
collateral, such as trademarks, accounts receivable, inventory, buildings, real
estate, franchises, and common and preferred stock in its subsidiaries and
affiliates. Collateral may also include guarantees or other credit support by
affiliates of the Borrower. In some cases, a collateralized Senior Loan may be
secured only by stock of the Borrower or its subsidiaries. The Loan Agreement
may or may not require the Borrower to pledge additional collateral to secure
the Senior Loan if the value of the initial collateral declines. In certain
circumstances, the Loan Agreement may authorize the Agent to liquidate the
collateral and to distribute the liquidation proceeds pro rata among the
Lenders. The Fund may invest up to 20% of its total assets in Senior Loans that
are not secured by specific collateral. Such unsecured Senior Loans involve a
greater risk of loss.
 
  Senior Loans also have contractual terms designed to protect Lenders. Loan
Agreements often include restrictive covenants that limit the activities of the
Borrower. These covenants may include mandatory prepayment out of excess cash
flows, restrictions on dividend payments, the maintenance of minimum financial
ratios, limits on indebtedness and other financial tests. Breach of these
covenants generally is an event of default and, if not waived by the Lenders,
may give Lenders the right to accelerate principal and interest payments.
 
   
  BORROWERS.  Senior Loans are loans made to corporations, partnerships and
other entities ("Borrowers"). Borrowers operate in a variety of industries and
geographic regions. The Fund does not intend to invest more than 5% of its total
assets in Senior Loans of a single Borrower. In addition, the Fund will not
invest more than 25% of its total assets in Borrowers that conduct their
principal businesses in the same industry. Most Senior Loans are made to U.S.
Borrowers. The Fund may, however, invest up to 20% of its total assets in Senior
Loans made to non-U.S. Borrowers. These Senior Loans must be U.S. dollar
denominated and pay principal and interest in U.S. dollars. Investing in Senior
Loans of non-U.S. Borrowers involves special risks. See "Special Risk
Considerations -- Investment in Non-U.S. Issuers."
    
 
  The capital structure of a Borrower may include Senior Loans, senior and
junior subordinated debt, preferred stock and common stock. Senior Loans
typically have the most senior claim on Borrower's assets and common stock the
most junior claim. The proceeds of Senior Loans that the Fund will purchase
usually will be used by Borrowers to finance leveraged buyouts,
recapitalizations, mergers, acquisitions, stock repurchases, debt refinancings
and, to a lesser extent, for general operating and other purposes.
 
  The Fund may purchase and retain in its portfolio Senior Loans of Borrowers
that have filed for protection under the federal bankruptcy laws or that have
had involuntary bankruptcy petitions filed against them by creditors. Because of
the protective features of Senior Loans, the Fund and the Adviser believe that
Senior Loans of Borrowers that either are experiencing, or are more likely to
experience, financial difficulty may represent attractive investment
opportunities. Investing in Senior Loans does, however, involve investment risk,
and some Borrowers default on their Senior Loan payments. The Fund attempts to
manage these risks through selection of a varied portfolio of Senior Loans and
analyses and monitoring of Borrowers.
 
  The Fund invests in a Senior Loan only if, in the Adviser's judgment, the
Borrower can meet its payment obligations. The Adviser performs its own
independent credit analysis of the Borrower in addition to utilizing information
prepared and supplied by the Agent or other Lenders. When evaluating a Borrower
the Adviser considers many factors, including the Borrower's past and future
projected financial performance. The Adviser also considers a Borrower's
management, collateral and industry. The Fund acquires a collateralized Senior
Loan only if the Adviser believes that the collateral coverage equals or exceeds
the outstanding principal amount of the Senior Loan. The Adviser continues to
monitor a
                                        9
<PAGE>   13
 
Borrower on an ongoing basis for so long as the Fund continues to own the Senior
Loan. Although the Adviser will use its best judgment in selecting Senior Loans,
there can be no assurance that such analysis will disclose factors that may
impair the value of a Senior Loan. You should expect the Fund's net asset value
to fluctuate as a result of changes in the credit quality of Borrowers and other
factors. A serious deterioration in the credit quality of a Borrower could cause
a permanent decrease in the Fund's net asset value. See "Special Risk
Considerations -- Borrower Credit Risk."
 
  The Adviser generally relies on its own credit analyses of Borrowers and not
on analyses prepared by ratings agencies or other independent parties. There is
no minimum rating or other independent evaluation of a Borrower or its
securities limiting the Fund's investments. Although a Senior Loan often is not
rated by any rating agency at the time the Fund purchases the Senior Loan,
rating agencies have become more active in rating an increasing number of Senior
Loans and at any given time a substantial portion of the Senior Loans in the
Fund's portfolio may be rated. The lack of a rating does not necessarily imply
that a Senior Loan is of lesser investment quality. There is no limit on the
percentage of the Fund's assets that may be invested in Senior Loans that are
rated below investment grade or that are unrated but of comparable quality.
 
   
  The following table sets forth the market value, based on the higher of
Standard & Poor's or Moody's Investors Service, Inc. rating categories, of the
Senior Loans held by the Fund as of January 31, 1999:

THE SENIOR LOAN PROCESS
 
  Senior Loans generally are negotiated between a Borrower and several financial
institutions ("Lenders") represented by one or more Lenders acting as agent
("Agent") of all the Lenders. The Agent is responsible for negotiating the loan
agreement ("Loan Agreement") that establishes the terms and conditions of the
Senior Loan and the rights of the Borrower and the Lenders. The Agent is paid a
fee by the Borrower for its services.
 
  The Agent generally is required to administer and manage the Senior Loan on
behalf of other Lenders. When evaluating Senior Loans, the Adviser may consider,
and may rely in part, on analysis performed by the Agent and other Lenders. This
analysis may include an evaluation of the value and sufficiency of any
collateral securing Senior Loans. As to collateralized Senior Loans, the Agent
usually is required to monitor the collateral. The Agent may rely on independent
appraisals of specific collateral. The Agent need not, however, obtain an
independent appraisal of assets pledged as collateral in all cases. The Agent
generally is also responsible for determining that the Lenders have obtained a
perfected security interest in the collateral securing a Senior Loan.
 
  The Fund normally relies on the Agent to collect principal of and interest on
a Senior Loan. Furthermore, the Fund also relies in part on the Agent to monitor
compliance by the Borrower with the restrictive covenants in the Loan Agreement
and to notify the Fund (or the Lender from who the Fund has purchased a
Participation) of any adverse change in the Borrower's financial condition. The
Fund acts as a Lender with respect to a syndicated Senior Loan only where the
Agent at the time of investment has outstanding debt or deposit obligations
rated investment grade by a rating agency or determined by the Adviser to be of
comparable quality. A rating agency's top four major rating categories generally
are considered to be investment grade. For a description of Moody's Investor's
Service, Inc. rating categories see Appendix A. The lowest tier of investment
grade rating is considered to have speculative characteristics. The Fund will
not purchase interests in Senior Loans unless the Agent, Lender and any other
person positioned between the Fund and the Borrower has entered into an
agreement that provides for the holding of assets in safekeeping for, or the
prompt disbursement of assets to, the Fund. Insolvency of the Agent or other
persons positioned between the Fund and the Borrower could result in losses for
the Fund. See "Special Risk Considerations -- Senior Loans."
 
  The Fund may be required to pay and may receive various fees and commissions
in connection with purchasing, selling and holding interests in Senior Loans.
The fees normally paid by Borrowers include three primary types: facility fees,
commitment fees and prepayment penalties. Facility fees are paid to Lenders when
a Senior Loan is originated. Commitment fees are paid to Lenders on an ongoing
basis based on the unused portion of a Senior Loan commitment. Lenders may
receive prepayment penalties when a Borrower prepays a Senior Loan. The Fund
receives these fees directly from the Borrower if the Fund is an Original Lender
(as defined below) or, in the case of commitment fees and
 
                                       10
<PAGE>   14
 
prepayment penalties, if the Fund acquires an Assignment. Whether the Fund
receives a facility fee in the case of an Assignment, or any fees in the case of
a Participation, depends on negotiations between the Fund and the Lender selling
such interests. When the Fund buys an Assignment, it may be required to pay a
fee, or forgo a portion of interest and fees payable to it, to the Lender
selling the Assignment. Occasionally, the assignor pays a fee to the assignee. A
person selling a Participation to the Fund may deduct a portion of the interest
and any fees payable to the Fund as an administrative fee. The Fund may be
required to pass along to a person that buys a Senior Loan from the Fund a
portion of any fees that the Fund is entitled to.
 
  The Fund may have obligations under a Loan Agreement, including the obligation
to make additional loans in certain circumstances. The Fund intends to reserve
against such contingent obligations by segregating cash, liquid securities and
liquid Senior Loans as a reserve. The Fund will not purchase a Senior Loan that
would require the Fund to make additional loans if as a result of such purchase
all of the Fund's additional loan commitments in the aggregate would exceed 20%
of the Fund's total assets or would cause the Fund to fail to meet the asset
composition requirements set forth under the heading "Investment Restrictions"
in the Statement of Additional Information.
 
TYPES OF SENIOR LOAN INVESTMENTS
 
  The Fund may act as one of the group of Lenders originating a Senior Loan (an
"Original Lender"), may purchase assignments or novations ("Assignments") of
portions of Senior Loans from third parties, and may invest in participations
("Participations") in Senior Loans. Senior Loans also include certain foreign
debt obligations that are in the form of notes rather than Loan Agreements. All
of these interests in Senior Loans are sometimes referred to simply as Senior
Loans.
 
  ORIGINAL LENDER.  When the Fund acts as an Original Lender it may participate
in structuring the Senior Loan. When the Fund is an Original Lender it will have
a direct contractual relationship with the Borrower, may enforce compliance by
the Borrower with the terms of the Loan Agreement and may have rights with
respect to any funds acquired by other Lenders through set-off. Lenders also
have full voting and consent rights under the applicable Loan Agreement. Action
subject to Lender vote or consent generally requires the vote or consent of the
holders of some specified percentage of the outstanding principal amount of the
Senior Loan. Certain decisions, such as reducing the amount of interest on or
principal of a Senior Loan, releasing collateral, changing the maturity of a
Senior Loan or a change in control of the Borrower frequently require the
unanimous vote or consent of all Lenders affected. The Fund will never act as
the Agent or principal negotiator or administrator of a Senior Loan.
 
  ASSIGNMENTS.  The purchaser of an Assignment typically succeeds to all the
rights and obligations under the Loan Agreement of the assigning Lender and
becomes a Lender under the Loan Agreement. Assignments may, however, be arranged
through private negotiations, and the rights and obligations acquired by the
purchaser of an Assignment may differ from, and be more limited than, those held
by the assigning Lender.
 
  PARTICIPATIONS.  When the Fund purchases a Participation in a Senior Loan, the
Fund will usually have a contractual relationship only with the Lender selling
the Participation and not with the Borrower. The Fund may have the right to
receive payments of principal, interest and any fees to which it is entitled
only from the Lender selling the Participation and only upon receipt by the
Lender of such payments from the Borrower. As a result, the Fund may assume the
credit risk of both the Borrower and the Lender selling the Participation. In
the event of insolvency of the Lender selling a Participation, the Fund may be
treated as a general creditor of the Lender.
 
  The Fund has taken the following measures in an effort to minimize these
risks. The Fund will only acquire Participations if the Lender selling the
Participation and any other persons positioned between the Fund and the Lender
(i) at the time of investment has outstanding debt or deposit obligations rated
investment grade by a rating Agency or determined by the Adviser to be of
comparable quality and (ii) has entered into an agreement which provides for the
holding of assets in safekeeping for, or the prompt disbursement of assets to,
the Fund.
 
  The Fund generally will not have the right to enforce compliance by the
Borrower with the Loan Agreement, nor rights to any funds acquired by other
Lenders through set-off against the Borrower. In addition, when the Fund holds a
Participation in a Senior Loan it may not have the right to vote on whether to
waive enforcement of any restrictive covenant breached by a Borrower. Lenders
voting in connection with a potential waiver of a restrictive covenant may have
interests different from those of the Fund and may not consider the interests of
the Fund. The Fund may not benefit directly from the collateral supporting a
Senior Loan in which it has purchased the Participation, although Lenders that
 
                                       11
<PAGE>   15
 
sell Participations generally are required to distribute liquidation proceeds
received by them pro rata among the holders of such Participations.
 
  OTHER SENIOR DEBT SECURITIES.  The Fund may invest up to 5% of its total
assets in certain senior debt securities that are in the form of notes or
assignments rather than Loan Agreements. The Fund expects to purchase these
senior debt securities only in the case of non-U.S. Borrowers. The Fund will
only purchase senior debt securities if (i) the senior debt securities represent
the only form of senior debt financing of the Borrower or (ii) the senior debt
securities are pari passu in the capital structure with other Senior Loans of a
Borrower and the Adviser determines that the terms, conditions, covenants and
collateral package of the senior debt securities are substantially similar, or
more favorable to the Fund, compared to the other Senior Loans of such Borrower.
There may be no person performing the role of the Agent for senior debt
securities. As a result, the Fund may be more dependent on the ability of the
Adviser to monitor and administer these Senior Loans. Senior debt securities
will be treated as Senior Loans for purposes of the Fund's policy of normally
investing at least 80% of its total assets in Senior Loans.
 
  The Fund also may invest up to 5% of its total assets in structured notes with
rates of return determined by reference to the total rate of return on one or
more Senior Loans referenced in such notes. The rate of return on the structured
note may be determined by applying a multiplier to the rate of total return on
the referenced loan or loans. Application of a multiplier is comparable to the
use of financial leverage, a speculative technique. Leverage magnifies the
potential for gain and the risk of loss; as a result, a relatively small decline
in the value of a referenced Senior Loan could result in a relatively large loss
in the value of a structured note. Structured notes will be treated as Senior
Loans for purposes of the Fund's policy of normally investing at least 80% of
its total assets in Senior Loans.
 
OTHER IMPORTANT INVESTMENT POLICIES
 
  The Fund may invest up to 20% of its total asset in warrants, equity
securities and junior debt securities acquired in connection with the
acquisition, restructuring or disposition of Senior Loans. The Fund also may
convert a warrant into the underlying security. Although the Fund generally will
acquire interests in warrants, equity and junior debt securities only when the
Adviser believes that the value being given by the Fund in exchange for such
interests is substantially outweighed by their potential value, investment in
warrants, equity and junior debt securities entails certain risks in addition to
those associated with investments in Senior Loans. These risks include the
potential for increasing fluctuations in the Fund's net asset value. Any equity
securities and junior debt securities held by the Fund will not be treated as
Senior Loans and thus will not count toward the 80% of the Fund's total assets
that normally will be invested in Senior Loans.
 
  During normal market conditions, the Fund may invest up to 20% of its total
assets in high quality, short-term debt securities with remaining maturities of
one year or less. These may include commercial paper rated at least in the top
two rating categories, or unrated commercial paper considered by the Adviser to
be of similar quality; interests in short-term loans of Borrowers having
short-term debt obligations rated or a short-term credit rating at least in such
top two rating categories, or having no rating but determined by the Adviser to
be of comparable quality; certificates of deposit and bankers' acceptances; and
securities issued or guaranteed by the U.S. government, its agencies or
instrumentalities. These securities may pay interest at adjustable rates or at
fixed rates. If the Adviser determines that market conditions temporarily
warrant a defensive investment policy, the Fund may invest, subject to its
ability to liquidate its relatively illiquid portfolio of Senior Loans, up to
100% of its assets in cash and such high quality, short-term debt securities.
 
- --------------------------------------------------------------------------------
                          SPECIAL RISK CONSIDERATIONS
- --------------------------------------------------------------------------------
 
  NO TRADING MARKET FOR SHARES. The Fund is a closed-end investment company
designed for long-term investors. The Fund does not intend to list the Shares
for trading on any national securities exchange. There is not expected to be any
secondary trading market in the Shares. The Shares are illiquid. In the event
that the Fund's Board of Trustees does not authorize the Fund to make
repurchases of its Shares, you will not be able to otherwise sell your Shares.
Even if the Fund does make repurchases, there is no guarantee that you will be
able to resell to the Fund all of the Shares that you desire to sell at any
particular time.
 
  SENIOR LOANS. There is less readily available, reliable information about most
Senior Loans than is the case for many other types of securities. In addition,
there is no minimum rating or other independent evaluation of a Borrower or its
securities limiting the Fund's investments, and the Adviser relies primarily on
its own evaluation of Borrower credit quality
 
                                       12
<PAGE>   16
 
rather than on any available independent sources. As a result, the Fund is
particularly dependent on the analytical abilities of the Adviser.
 
  Senior Loans are not listed on any national securities exchange or automated
quotation system and no active trading market exists for many Senior Loans. As a
result, many Senior Loans are illiquid, meaning that the Fund may not be able to
sell them quickly at a fair price. The market for illiquid securities is more
volatile than the market for liquid securities. However, many Senior Loans are
of a large principal amount and are held by a large number of owners. In the
Adviser's opinion, this should enhance their liquidity. In addition, in recent
years the number of institutional investors purchasing Senior Loans has
increased. The risks of illiquidity are particularly important when the Fund's
operations require cash, and may in certain circumstances require that the Fund
borrow to meet short-term cash requirements. To the extent that a secondary
market does exist for certain Senior Loans, the market may be subject to
irregular trading activity, wide bid/ask spreads and extended trade settlement
periods. The Fund has no limitation on the amount of its assets that may be
invested in securities that are not readily marketable or that are subject to
restrictions on resale. The substantial portion of the Fund's assets invested in
Senior Loans may restrict the ability of the Fund to dispose of its investments
in a timely fashion and at a fair price, and could result in capital losses to
the Fund and holders of Shares. The market for Senior Loans could be disrupted
in the event of an economic downturn or a substantial increase or decrease in
interest rates. This could result in increased volatility in the market and in
the Fund's net asset value and market price per Share. Illiquid securities are
also difficult to value.
 
  If legislation or state or federal regulators impose additional requirements
or restrictions on the ability of financial institutions to make loans that are
considered highly leveraged transactions, the availability of Senior Loans for
investment by the Fund may be adversely affected. In addition, such requirements
or restrictions could reduce or eliminate sources of financing for certain
Borrowers. This would increase the risk of default. If legislation or federal or
state regulators require financial institutions to dispose of Senior Loans that
are considered highly leveraged transactions or subject such Senior Loans to
increased regulatory scrutiny, financial institutions may determine to sell such
Senior Loans. Such sales could result in prices that, in the opinion of the
Adviser, do not represent fair value. If the Fund attempts to sell a Senior Loan
at a time when a financial institution is engaging in such a sale, the price the
Fund could get for the Senior Loan may be adversely affected.
 
  Selling Lenders and other persons positioned between the Fund and the Borrower
will likely conduct their principal business activities in the banking, finance
and financial services industries. The Fund may be more at risk to any single
economic, political or regulatory occurrence affecting such industries. Persons
engaged in such industries may be more susceptible to, among other things,
fluctuations in interest rates, changes in the Federal Open Market Committee's
monetary policy, governmental regulations concerning such industries and
concerning capital raising activities generally and fluctuations in the
financial markets generally.
 
  Should an Agent or a Lender positioned between the Fund and a Borrower become
insolvent or enter FDIC receivership or bankruptcy, where the Fund is an
Original Lender or has purchased an Assignment any interest of such person in
the Senior Loan and in any loan payment held by such person for the benefit of
the Fund should not be included in the person's estate. If, however, these items
are included in their estate, the Fund would incur costs and delays in realizing
payment and could suffer a loss of principal or interest.
 
  Some Senior Loans are subject to the risk that a court, pursuant to fraudulent
conveyance or other similar laws, could subordinate the Senior Loans to
presently existing or future indebtedness of the Borrower or take other action
detrimental to Lenders. Such court action could under certain circumstances
include invalidation of Senior Loans.
 
  BORROWER CREDIT RISK. Senior Loans, like most other debt obligations, are
subject to the risk of default. Default in the payment of interest or principal
on a Senior Loan results in a reduction in income to the Fund, a reduction in
the value of the Senior Loan and a potential decrease in the Fund's net asset
value. The risk of default increases in the event of an economic downturn or a
substantial increase in interest rates. An increased risk of default could
result in a decline in the value of Senior Loans and in the Fund's net asset
value.
 
  The Fund may acquire Senior Loans of Borrowers that are experiencing, or are
more likely to experience, financial difficulty, including Senior Loans of
Borrowers that have filed for bankruptcy protection. Borrowers may have
outstanding debt obligations that are rated below investment grade. More
recently, rating agencies have begun rating Senior Loans, and Senior Loans in
the Fund's portfolio may themselves be rated below investment grade. The Fund
may invest a substantial portion of its assets in Senior Loans of Borrowers that
have outstanding debt obligations rated below investment
 
                                       13
<PAGE>   17
 
   
grade or that are unrated but of comparable quality to such securities. Debt
securities rated below investment grade are viewed by the rating agencies as
speculative and are commonly known as "junk bonds." Senior Loans generally are
not rated at the time that the Fund purchases them. If a Senior Loan is rated at
the time of purchase, the Adviser may consider the rating when evaluating the
Senior Loan but, in any event, does not view ratings as a determinative factor
in investment decisions. As a result, the Fund is more dependant on the
Adviser's credit analysis abilities. Because of the protective terms of Senior
Loans, the Adviser believes that the Fund is more likely to recover more of its
investment in a defaulted Senior Loan than would be the case for most other
types of defaulted debt securities. The values of Senior Loans of Borrowers that
have filed for bankruptcy protection or that are experiencing payment difficulty
will reflect, among other things, the Adviser's assessment of the likelihood
that the Fund ultimately will receive repayment of the principal amount of such
Senior Loans, the likely duration, if any, of a lapse in the scheduled payment
of interest and repayment of principal and prevailing interest rates. As of
January 31, 1999, the Fund held in its portfolio and had reduced the value of 5
Senior Loans (the aggregate value of which represented approximately 1.0% of the
value of the Fund's net assets on such date) of Borrowers that were subject to
protection under the federal bankruptcy laws.
    
 
  In the case of collateralized Senior Loans, there is no assurance that sale of
the collateral would raise enough cash to satisfy the Borrower's payment
obligation or that the collateral can or will be liquidated. In the event of
bankruptcy, liquidation may not occur and the court may not give Lenders the
full benefit of their senior positions. If the terms of a Senior Loan do not
require the Borrower to pledge additional collateral in the event of a decline
in the value of the original collateral, the Fund will be exposed to the risk
that the value of the collateral will not at all times equal or exceed the
amount of the Borrower's obligations under the Senior Loans. To the extent that
a Senior Loan is collateralized by stock in the Borrower or its subsidiaries,
such stock may lose all of its value in the event of bankruptcy of the Borrower.
Uncollateralized Senior Loans involve a greater risk of loss.
 
  YEAR 2000 READINESS DISCLOSURE. The following two paragraphs constitute "Year
2000 Readiness Disclosure" within the meaning of the Year 2000 Information and
Readiness Disclosure Act of 1998.
 
  Like other investment companies, financial and business organizations and
individuals around the world, the Fund could be adversely affected if the
computer systems used by the Fund's Adviser, Administrator and other service
providers do not properly process and calculate date-related information and
data from and after January 1, 2000. This is commonly known as the "Year 2000
Problem." The Adviser and Administrator are taking steps that they believe are
reasonably designed to address the Year 2000 Problem with respect to computer
systems that they use and to obtain reasonable assurances that comparable steps
are being taken by each of the Fund's other major service providers. At this
time, there can be no assurance that these steps will be sufficient to avoid any
adverse impact to the Fund.
 
  In addition, it is possible that the markets for Senior Loans and other
securities in which the Fund invests may be detrimentally affected by computer
failures throughout the financial services industry beginning January 1, 2000.
Improperly functioning trading systems may result in settlement problems and
liquidity issues. Moreover, corporate and governmental data processing errors
may result in production problems for individual companies and overall economic
uncertainties. Earnings of individual issuers will be affected by remediation
costs, which may be substantial and may be reported inconsistently in U.S. and
foreign financial statements. Accordingly, the Fund's investments may be
adversely affected.
 
   
  INVESTMENT IN NON-U.S. ISSUERS. The Fund may invest up to 20% of its total
assets, measured at the time of investment, in U.S. dollar denominated Senior
Loans to Borrowers that are organized or located in countries other than the
United States. Although the Senior Loans will require payment of interest and
principal in U.S. dollars, these Borrowers may have significant non-U.S. dollar
revenues. Investment in non-U.S. issuers involves special risks, including that
non-U.S. issuers may be subject to less rigorous accounting and reporting
requirements than U.S. issuers, less rigorous regulatory requirements, differing
legal systems and laws relating to creditors' rights, the potential inability to
enforce legal judgments, fluctuations in currency values and the potential for
political, social and economic adversity.
    
 
  EQUITY SECURITIES AND JUNIOR DEBT SECURITIES. Warrants, equity securities and
junior debt securities have a subordinate claim on a Borrower's assets as
compared with Senior Loans. As a result, the values of warrants, equity
securities and junior debt securities generally are more dependent on the
financial condition of the Borrower and less dependent on fluctuations in
interest rates than are the values of many debt securities. The values of
warrants, equity securities and junior debt securities may be more volatile than
those of Senior Loans and thus may increase the volatility of the Fund's net
asset value.
                                       14
<PAGE>   18
 
  PARTICIPATIONS. The Fund may purchase Participations in Senior Loans. Under a
Participation the Fund generally will have rights that are more limited than the
rights of Lenders or of persons who acquire a Senior Loan by Assignment. In a
Participation the Fund typically has a contractual relationship with the Lender
selling the Participation, but not with the Borrower. As a result, the Fund
assumes the credit risk of the Lender selling the Participation in addition to
the credit risk of the Borrower. In the event of the insolvency of the Lender
selling the Participation, the Fund may be treated as a general creditor of the
Lender and may not have a senior claim to the Lender's interest in the Senior
Loan.
 
  FUND BORROWINGS. The Fund is authorized to borrow money in an amount up to
33 1/3% of the Fund's total assets (including the amount borrowed) to finance
repurchases of Shares. The rights of any lenders to the Fund to receive payments
of interest on and repayments of principal of any borrowings will be senior to
the rights of Shareholders. The loan agreement for any borrowing likely will
limit certain activities of the Fund, including the payment of dividends to
holders of Shares in certain circumstances. Interest payments and fees incurred
in connection with borrowings will reduce the amount of net income available for
payment to Shareholders. Borrowings may also result in greater volatility in the
Fund's net asset value. The Fund will not use borrowings for investment leverage
purposes. Accordingly, the Fund will not purchase additional portfolio
securities at any time that borrowings exceed 5% of the Fund's total assets
(including the amount borrowed). See "Repurchase of Shares."
 
  NON-DIVERSIFIED STATUS. The Fund has registered as a "non-diversified"
investment company. This means that it may invest more than 5% of the value of
its assets in the obligations of any single issuer, including Senior Loans of a
single Borrower and Participations purchased from a single Lender. Although the
Fund does not intend to invest more than 5% of the value of its assets in Senior
Loans of a single Borrower, it may invest more than 5% of its assets in
Participations purchased from a single Lender. If the Fund invests a relatively
high percentage of its assets in obligations of a limited number of issuers, the
Fund will be more at risk to any single corporate, economic, political or
regulatory event that impacts one or more of those issuers.
 
  ANTI-TAKEOVER PROVISIONS. The Fund's Declaration of Trust includes provisions
that could limit the ability of other persons to acquire control of the Fund or
to change the composition of its Board of Trustees. See "Description of Capital
Structure -- Anti-Takeover Provisions in the Declaration of Trust."
 
- --------------------------------------------------------------------------------
INVESTMENT PRACTICES AND SPECIAL RISKS
- --------------------------------------------------------------------------------
 
  The Fund may: use interest rate and other hedging transactions, lend portfolio
holdings, purchase and sell Senior Loans and other securities on a "when issued"
or "delayed delivery" basis, and use repurchase and reverse repurchase
agreements. These investment practices involve risks. Although the Adviser
believes that these investment practices may aid the Fund in achieving its
investment objective, there is no assurance that these practices will achieve
this result.
 
INTEREST RATE AND OTHER HEDGING TRANSACTIONS
 
  The Fund may enter into various interest rate hedging and risk management
transactions. Certain of these interest rate hedging and risk management
transactions may be considered to involve derivative instruments. A derivative
is a financial instrument whose performance is derived at least in part from the
performance of an underlying index, security or asset. The values of certain
derivatives can be affected dramatically by even small market movements,
sometimes in ways that are difficult to predict. There are many different types
of derivatives, with many different uses. The Fund expects to enter into these
transactions primarily to seek to preserve a return on a particular investment
or portion of its portfolio, and may also enter into such transactions to seek
to protect against decreases in the anticipated rate of return on floating or
variable rate financial instruments the Fund owns or anticipates purchasing at a
later date, or for other risk management strategies such as managing the
effective dollar-weighted average duration of the Fund's portfolio. In addition,
the Fund may also engage in hedging transactions to seek to protect the value of
its portfolio against declines in net asset value resulting from changes in
interest rates or other market changes. The Fund does not intend to engage in
such transactions to enhance the yield on its portfolio to increase income
available for distributions. Market conditions will determine whether and in
what circumstances the Fund would employ any of the hedging and risk management
techniques described below. The Fund will not engage in any of the transactions
for speculative purposes and will use them only as a means to hedge or manage
the risks associated with assets held in, or anticipated to be purchased for,
the Fund's portfolio or obligations incurred by the Fund. The successful
utilization of hedging and risk management transactions requires skills
different from those
 
                                       15
<PAGE>   19
 
needed in the selection of the Fund's portfolio securities. The Fund believes
that the Adviser possesses the skills necessary for the successful utilization
of hedging and risk management transactions. The Fund will incur brokerage and
other costs in connection with its hedging transactions.
 
  The Fund may enter into interest rate swaps or purchase or sell interest rate
caps or floors. The Fund will not sell interest rate caps or floors that it does
not own. Interest rate swaps involve the exchange by the Fund with another party
of their respective obligations to pay or receive interest, e.g., an exchange of
an obligation to make floating rate payments for an obligation to make fixed
rate payments. For example, the Fund may seek to shorten the effective interest
rate redetermination period of a Senior Loan in its portfolio the Borrower to
which has selected an interest rate redetermination period of one year. The Fund
could exchange the Borrower's obligation to make fixed rate payments for one
year for an obligation to make payments that readjust monthly. In such event,
the Fund would consider the interest rate redetermination period of such Senior
Loan to be the shorter period.
 
  The purchase of an interest rate cap entitles the purchaser, to the extent
that a specified index exceeds a predetermined interest rate, to receive
payments of interest at the difference of the index and the predetermined rate
on a notional principal amount (the reference amount with respect to which
interest obligations are determined although no actual exchange of principal
occurs) from the party selling such interest rate cap. The purchase of an
interest rate floor entitles the purchaser, to the extent that a specified index
falls below a predetermined interest rate, to receive payments of interest at
the difference of the index and the predetermined rate on a notional principal
amount from the party selling such interest rate floor. The Fund will not enter
into swaps, caps or floors if, on a net basis, the aggregate notional principal
amount with respect to such agreements exceeds the net assets of the Fund.
 
  In circumstances in which the Adviser anticipates that interest rates will
decline, the Fund might, for example, enter into an interest rate swap as the
floating rate payor or, alternatively, purchase an interest rate floor. In the
case of purchasing an interest rate floor, if interest rates declined below the
floor rate, the Fund would receive payments from its counterparty which would
wholly or partially offset the decrease in the payments it would receive in
respect of the portfolio assets being hedged. In the case where the Fund
purchases such an interest rate swap, if the floating rate payments fell below
the level of the fixed rate payment set in the swap agreement, the Fund's
counterparty would pay the Fund amounts equal to interest computed at the
difference between the fixed and floating rates over the notional principal
amount. Such payments would offset or partially offset the decrease in the
payments the Fund would receive in respect of floating rate portfolio assets
being hedged.
 
  The successful use of swaps, caps and floors to preserve the rate of return on
a portfolio of financial instruments depends on the Adviser's ability to predict
correctly the direction and extent of movements in interest rates. Although the
Fund believes that use of the hedging and risk management techniques described
above will benefit the Fund, if the Adviser's judgment about the direction or
extent of the movement in interest rates in incorrect, the Fund's overall
performance would be worse than if it had not entered into any such
transactions. For example, if the Fund had purchased an interest rate swap or an
interest rate floor to hedge against its expectation that interest rates would
decline but instead interest rates rose, the Fund would lose part or all of the
benefit of the increased payments it would receive as a result of the rising
interest rates because it would have to pay amounts to its counterparty under
the swap agreement or would have paid the purchase price of the interest rate
floor.
 
  Inasmuch as these hedging transactions are entered into for good-faith risk
management purposes, the Adviser and the Fund believe such obligations do not
constitute senior securities. The Fund will usually enter into interest rate
swaps on a net basis, i.e., where the two parties make net payments with the
Fund receiving or paying, as the case may be, only the net amount of the two
payments. The net amount of the excess, if any, of the Fund's obligations over
its entitlements with respect to each interest rate swap will be accrued and an
amount of cash or liquid securities having an aggregate net asset value at least
equal to the accrued excess will be maintained in a segregated account by the
Fund's custodian. If the Fund enters into a swap on other than a net basis, the
Fund will maintain in the segregated account the full amount of the Fund's
obligations under each such swap. Accordingly, the Fund does not treat swaps as
senior securities. The Fund may enter into swaps, caps and floors with member
banks of the Federal Reserve System, members of the New York Stock Exchange or
other entities determined by the Adviser, pursuant to procedures adopted and
reviewed on an ongoing basis by the Board of Trustees, to be creditworthy. If a
default occurs by the other party to such transaction, the Fund will have
contractual remedies pursuant to the agreements related to the transaction but
such remedies may be subject to bankruptcy and insolvency laws which could
affect the Fund's rights as a creditor. The swap market has grown
 
                                       16
<PAGE>   20
 
substantially in recent years with a large number of banks and financial
services firms acting both as principals and as agents utilizing standardized
swap documentation. As a result, the swap market has become relatively liquid.
Caps and floors are more recent innovations and they are less liquid than swaps.
There can be no assurance, however, that the Fund will be able to enter into
interest rate swaps or to purchase interest rate caps or floors at prices or on
terms the Adviser believes are advantageous to the Fund. In addition, although
the terms of interest rate swaps, caps and floors may provide for termination,
there can be no assurance that the Fund will be able to terminate an interest
rate swap or to sell or offset interest rate caps or floors that it has
purchased.
 
  New financial products continue to be developed and the Fund may invest in any
such products as may be developed to the extent consistent with its investment
objective and the regulatory and federal tax requirements applicable to
investment companies.
 
LENDING OF PORTFOLIO HOLDINGS
 
  The Fund may seek to increase its income by lending financial instruments in
its portfolio in accordance with present regulatory policies, including those of
the Board of Governors of the Federal Reserve System and the SEC. Such loans may
be made, without limit, to brokers, dealers, banks or other recognized
institutional borrowers of financial instruments and would be required to be
secured continuously by collateral, including cash, cash equivalents or U.S.
Treasury bills maintained on a current basis at an amount at least equal to the
market value of the financial instruments loaned. The Fund would have the right
to call a loan and obtain the financial instruments loaned at any time on five
days' notice. For the duration of a loan, the Fund would continue to receive the
equivalent of the interest paid by the issuer on the financial instruments
loaned and also would receive compensation from the investment of the
collateral. The Fund would not have the right to vote any financial instruments
having voting rights during the existence of the loan, but the Fund could call
the loan in anticipation of an important vote to be taken among holders of the
financial instruments or in anticipation of the giving or withholding of their
consent on a material matter affecting the financial instruments. As with other
extensions of credit, risks of delay in recovery or even loss of rights in the
collateral exist should the borrower of the financial instruments fail
financially. However, the loans would be made only to firms deemed by the
Adviser to be of good standing and when, in the judgment of the Adviser, the
consideration which can be earned currently from loans of this type justifies
the attendant risk. The creditworthiness of firms to which the Fund lends its
portfolio holdings will be monitored on an ongoing basis by the Adviser pursuant
to procedures adopted and reviewed, on an ongoing basis, by the Board of
Trustees of the Fund. No specific limitation exists as to the percentage of the
Fund's assets which the Fund may lend.
 
"WHEN ISSUED" AND "DELAYED DELIVERY" TRANSACTIONS
 
  The Fund may also purchase and sell interests in Senior Loans and other
portfolio securities on a "when issued" and "delayed delivery" basis. No income
accrues to the Fund on such interests or securities in connection with such
purchase transactions prior to the date the Fund actually takes delivery of such
interests or securities. These transactions are subject to market fluctuation;
the value of the interests in Senior Loans and other portfolio debt securities
at delivery may be more or less than their purchase price, and yields generally
available on such interests or securities when delivery occurs may be higher or
lower than yields on the interests or securities obtained pursuant to such
transactions. Because the Fund relies on the buyer or seller, as the case may
be, to consummate the transaction, failure by the other party to complete the
transaction may result in the Fund missing the opportunity of obtaining a price
or yield considered to be advantageous. When the Fund is the buyer in such a
transaction, however, it will maintain, in a segregated account with its
custodian, cash or liquid securities having an aggregate value equal to the
amount of such purchase commitments until payment is made. The Fund will make
commitments to purchase such interests or securities on such basis only with the
intention of actually acquiring these interests or securities, but the Fund may
sell such interests or securities prior to the settlement date if such sale is
considered to be advisable. To the extent the Fund engages in "when issued" and
"delayed delivery" transactions, it will do so for the purpose of acquiring
interests or securities for the Fund's portfolio consistent with the Fund's
investment objective and policies and not for the purpose of investment
leverage. No specific limitation exists as to the percentage of the Fund's
assets which may be used to acquire securities on a "when issued" or "delayed
delivery" basis.
 
REPURCHASE AGREEMENTS
 
  The Fund may enter into repurchase agreements (a purchase of, and a
simultaneous commitment to resell, a financial instrument at an agreed upon
price on an agreed upon date) only with member banks of the Federal Reserve
System and
                                       17
<PAGE>   21
 
member firms of the New York Stock Exchange. When participating in repurchase
agreements, the Fund buys securities from a vendor, e.g., a bank or brokerage
firm, with the agreement that the vendor will repurchase the securities at a
higher price at a later date. Such transactions afford an opportunity for the
Fund to earn a return on available cash at minimal market risk, although the
Fund may be subject to various delays and risks of loss if the vendor is unable
to meet its obligation to repurchase. Under the 1940 Act, repurchase agreements
are deemed to be collateralized loans of money by the Fund to the seller. In
evaluating whether to enter into a repurchase agreement, the Adviser will
consider carefully the creditworthiness of the vendor. If the member bank or
member firm that is the party to the repurchase agreement petitions for
bankruptcy or otherwise becomes subject to the U.S. Bankruptcy Code, the law
regarding the rights of the Fund is unsettled. The securities underlying a
repurchase agreement will be marked to market every business day so that the
value of the collateral is at least equal to the value of the loan, including
the accrued interest thereon, and the Adviser will monitor the value of the
collateral. No specific limitation exists as to the percentage of the Fund's
assets which may be used to participate in repurchase agreements.
 
REVERSE REPURCHASE AGREEMENTS
 
  The Fund may enter into reverse repurchase agreements with respect to debt
obligations which could otherwise be sold by the Fund. A reverse repurchase
agreement is an instrument under which the Fund may sell an underlying debt
instrument and simultaneously obtain the commitment of the purchaser (a
commercial bank or a broker or dealer) to sell the security back to the Fund at
an agreed upon price on an agreed upon date. The Fund will maintain in a
segregated account with its custodian cash or liquid securities in an amount
sufficient to cover its obligations with respect to reverse repurchase
agreements. The Fund receives payment for such securities only upon physical
delivery or evidence of book entry transfer by its custodian. Regulations of the
SEC require either that securities sold by the Fund under a reverse repurchase
agreement be segregated pending repurchase or that the proceeds be segregated on
the Fund's books and records pending repurchase. Reverse repurchase agreements
could involve certain risks in the event of default or insolvency of the other
party, including possible delays or restrictions upon the Fund's ability to
dispose of the underlying securities. An additional risk is that the market
value of securities sold by the Fund under a reverse repurchase agreement could
decline below the price at which the Fund is obligated to repurchase them.
Reverse repurchase agreements will be considered borrowings by the Fund and as
such would be subject to the restrictions on borrowing described in the
Statement of Additional Information under "Investment Restrictions." The Fund
will not hold more than 5% of the value of its total assets in reverse
repurchase agreements.
 
- --------------------------------------------------------------------------------
TAXATION
- --------------------------------------------------------------------------------
 
  The Fund has qualified and intends to continue to qualify each year to be
treated as a regulated investment company under Subchapter M of the Code. If the
Fund so qualifies and distributes each year to its shareholders at least 90% of
its net investment income (including, among other things, interest and net
short-term capital gains, but not net capital gains, which are the excess of net
long-term capital gains over net short-term capital losses) in each year, the
Fund will not be required to pay federal income taxes on any income distributed
to shareholders. The Fund will not be subject to federal income tax on any net
capital gains distributed to shareholders. As a Massachusetts business trust,
the Fund will not be subject to any excise or income taxes in Massachusetts as
long as it qualifies as a regulated investment company for federal income tax
purposes.
 
  If the Fund failed to qualify as a regulated investment company or failed to
satisfy the 90% distribution requirement in any taxable year, the Fund would be
taxed as an ordinary corporation on its taxable income (even if such income were
distributed to its shareholders) and all distributions out of earnings and
profits would be taxed to shareholders as ordinary income.
 
  Distributions. Distributions of the Fund's net investment income are taxable
to holders of Shares as ordinary income, whether paid in cash or reinvested in
additional Shares. Distributions of the Fund's net capital gains ("capital gain
dividends"), if any, are taxable to holders of Shares at the rates applicable to
long-term capital gains regardless of the length of time shares of the Fund have
been held by such shareholders. For a summary of the tax rates applicable to
capital gains (including capital gain dividends), see "Capital Gains Rates"
below. The Fund will inform shareholders of the source and tax status of all
distributions promptly after the close of each calendar year.
 
                                       18
<PAGE>   22
 
  Sale of Shares. Except as discussed below, selling shareholders will generally
recognize gain or loss in an amount equal to the difference between their
adjusted tax basis in the Shares and the amount received. If such Shares are
held as a capital asset, the gain or loss will be a capital gain or loss. For a
summary of the tax rates applicable to capital gains, see "Capital Gains Rates"
below. It is possible, although the Fund believes it is unlikely, that, in
connection with a tender offer, distributions to tendering shareholders may be
subject to tax as ordinary income (rather than as gain or loss), which in turn
may result in deemed distributions subject to tax as ordinary income for
non-tendering shareholders. The federal income tax consequences of the
repurchase of Shares pursuant to tender offers will be disclosed in the related
offering documents. Any loss recognized upon a taxable disposition of Shares
held for six months or less will be treated as a long-term capital loss to the
extent of any capital gain dividends received with respect to such Shares. For
purposes of determining whether Shares have been held for six months or less,
the holding period is suspended for any periods during which the shareholder's
risk of loss is diminished as a result of holding one or more other positions in
substantially similar or related property or through certain options or short
sales.
 
  Capital Gains Rates. The maximum tax rate applicable to net capital gains
recognized by individuals and certain other non-corporate taxpayers is (i) the
same as the maximum ordinary income tax rate for capital assets held for one
year or less or (ii) 20% for capital assets held for more than one year. The
maximum long-term capital gains rate for corporations is 35%.
 
  General. The federal income tax discussion set forth above is for general
information only. Prospective investors should consult their advisors regarding
the specific federal and state tax consequences of purchasing, holding and
disposing of Shares, as well as the effects of other state, local and foreign
tax laws and any proposed tax law changes.

MANAGEMENT OF THE FUND
- --------------------------------------------------------------------------------
 
BOARD OF TRUSTEES
 
  The management of the Fund, including general supervision of the duties
performed by the Adviser under the Advisory Agreement, is the responsibility of
the Fund's Board of Trustees.
 
THE ADVISER
 
  Van Kampen Investment Advisory Corp. (the "Adviser") is the Fund's investment
adviser. The Adviser is a wholly-owned subsidiary of Van Kampen Investments Inc.
Van Kampen Investments Inc. is an indirect wholly-owned subsidiary of Morgan
Stanley Dean Witter & Co. The Adviser's principal office is located at 1
Parkview Plaza, P.O. Box 5555, Oakbrook Terrace, Illinois 60181-5555.
 
   
  Van Kampen Investments Inc. is a diversified asset management company with
more than two million retail investor accounts, extensive capabilities for
managing institutional portfolios, and more than $75 billion under management or
supervision. Van Kampen Investments Inc.'s more than 50 open-end and 39
closed-end funds and more than 2,500 unit investment trusts are professionally
distributed by leading financial advisers nationwide.
    
 
  Morgan Stanley Dean Witter & Co. and various of its directly or indirectly
owned subsidiaries, including Morgan Stanley Asset Management Inc., an
investment adviser, Morgan Stanley & Co. Incorporated, a registered
broker-dealer and investment adviser, and Morgan Stanley International are
engaged in a wide range of financial services. Their principal businesses
include securities underwriting, distribution and trading; merger, acquisition,
restructuring and other corporate finance advisory activities; merchant banking;
stock brokerage and research services; credit services; asset management;
trading of futures, options, foreign exchange, commodities and swaps (involving
foreign exchange, commodities, indices and interest rates); real estate advice,
financing and investing; and securities lending.
 
  INVESTMENT ADVISORY AGREEMENT. Subject to the authority of the Board of
Trustees, the Adviser and the Fund's officers will supervise and implement the
Fund's investment activities and will be responsible for overall management of
the Fund's business affairs. The investment advisory agreement (the "Advisory
Agreement") between the Adviser and the
 
                                       19
<PAGE>   23
 
Fund requires the Adviser to supply investment research and portfolio
management. The Adviser's responsibilities include, but are not limited to:
 
  - selecting which securities the Fund should purchase, hold or sell;
 
  - choosing the brokers through which the Fund will execute its portfolio
    transactions,
 
  - furnishing offices, necessary facilities and equipment, and
 
  - permitting the use of its officers and employees to serve without
    compensation as Trustees and officers of the fund.
 
  For the services provided by the Adviser under the Advisory Agreement, the
Fund will pay the Adviser an annualized fee (accrued daily and paid monthly)
equal to the percentage of the Fund's average net assets shown in the table
below. The advisory fee is higher than the fees paid by most management
investment companies, although it is comparable to the fees paid by several
publicly offered, closed-end management investment companies with investment
objectives and policies similar to those of the Fund.

  PORTFOLIO MANAGEMENT. Jeffrey W. Maillet is a Senior Vice President of the
Adviser and has been primarily responsible for the day to day management of the
Fund's portfolio since the Fund commenced investment operations. Mr. Maillet has
been employed by the Adviser since 1989. Mr. Maillet also has primary
responsibility for the day to day management of the portfolio of the Van Kampen
Senior Floating Rate Fund, a continuously offered closed-end investment company,
and Van Kampen Senior Income Trust, a closed-end investment company listed on
the New York Stock Exchange, both investing primarily in Senior Loans and having
investment objectives and policies substantially similar to those of the Fund.
 
  THE ADMINISTRATOR. The administrator for the Fund is Van Kampen Investments
Inc. ("Van Kampen" and in such capacity, the "Administrator"). Its principal
business address is 1 Parkview Plaza, P.O. Box 5555, Oakbrook Terrace, Illinois
60181-5555. The Administrator is the parent company of the Adviser.
 
  Pursuant to the administration agreement between the Fund and the
Administrator (the "Administration Agreement"), the Administrator (i) monitors
provisions of Loan Agreements and any Participations and Assignments and is
responsible for recordkeeping for Senior Loans; (ii) arranges for the printing
and dissemination of reports to holders of Shares; (iii) arranges for
dissemination of the Fund's proxy and any tender offer materials to holders of
Shares, and oversees the tabulation of proxies by the Fund's transfer agent;
(iv) negotiates the terms and conditions under which custodian services are
provided to the Fund and the fees to be paid by the Fund in connection
therewith; (v) negotiates the terms and conditions under which dividend
disbursing services are provided to the Fund, and the fees to be paid by the
Fund in connection therewith and reviews the provision of dividend disbursing
services to the Fund; (vi) provides the Fund's dividend disbursing agent and
custodian with such information as is required for them to effect payment of
dividends and distributions and to implement the Fund's dividend reinvestment
plan; (vii) makes such reports and recommendations to the Board of Trustees as
the Trustees reasonably request; and (viii) provides shareholder services to
holders or potential holders of the Fund's securities.
 
  For the services rendered to the Fund and related expenses borne by the
Administrator, the Fund pays the Administrator a fee, accrued daily and paid
monthly, at the annualized rate of 0.25% of the Fund's net assets.
 
- --------------------------------------------------------------------------------
DISTRIBUTIONS
- --------------------------------------------------------------------------------
 
  The Fund's present policy is to declare daily and pay monthly distributions to
holders of Shares of substantially all net investment income of the Fund. Net
investment income consists of all interest income, fee income and other ordinary
income earned by the Fund and net short-term capital gains, less all expenses of
the Fund. Expenses of the Fund are accrued each day. Distributions cannot be
assured, and the amount of each monthly distribution is likely to vary. Net
 
                                       20
<PAGE>   24
 
realized long-term capital gains, if any, generally will be distributed at least
annually. You may elect to have distributions automatically reinvested in
additional Shares. See "Dividend Reinvestment Plan."
 
- --------------------------------------------------------------------------------
DIVIDEND REINVESTMENT PLAN
- --------------------------------------------------------------------------------
 
  You may choose to have your dividend and capital gain distributions reinvested
in additional Shares at net asset value (without a sales charge). If you do not
make this election, all distributions will be made in cash.
 
  All correspondence concerning the dividend reinvestment plan should be
directed to the State Street Bank and Trust Company, as Plan Agent, c/o Van
Kampen Investor Services Inc., P.O. Box 418256, Kansas City, MO 64153-9256.
Please call (800) 341-2911 between the hours of 7:00 a.m. and 7:00 p.m. Central
Standard Time if you have questions regarding the Plan. See "Dividend
Reinvestment Plan" in the Statement of Additional Information.
 
  DIVIDEND DIVERSIFICATION. A shareholder also may, upon written request by
completing the appropriate section of the application form or by calling (800)
341-2911 ((800) 421-2833 for the hearing impaired), elect to have all dividends
and other distributions paid on Shares invested into shares of certain mutual
funds advised by the Adviser or its affiliates, so long as a pre-existing
account for such shares exists for the shareholder. A shareholder may call the
phone numbers shown above to obtain a list of the mutual funds available and to
request current prospectuses.
 
  If the qualified pre-existing account does not exist, the shareholder must
establish a new account subject to minimum investment and other requirements of
the fund into which distributions would be invested. Distributions are invested
into the selected fund at its net asset value as of the distribution payment
date. Purchases may be made only if shares of the selected fund are available
for sale in the investor's state.
- --------------------------------------------------------------------------------
REPURCHASE OF SHARES
- --------------------------------------------------------------------------------
  The Board of Trustees of the Fund currently intends, each quarter, to consider
authorizing the Fund to repurchase Shares through a tender offer for all or a
portion of the Fund's then outstanding Shares. Such repurchases would be made at
the net asset value of the Shares on the expiration date of the tender offer.
Management of the Fund expects to recommend that the Board of Trustees approve
such repurchases quarterly. Although tender offers, if undertaken and completed,
will provide some liquidity for holders of the Shares, there is no assurance
that tender offers will in fact be undertaken or completed or, if completed,
that they will provide sufficient liquidity for all holders of Shares who may
desire to sell such Shares. As such, investment in the Shares should be
considered illiquid. As of the date of this Prospectus, the Fund has commenced
and consummated tender offers in each quarter since the commencement of
investment operations. An early withdrawal charge payable to VKF will be imposed
on most Shares accepted for tender by the Fund which have been held for less
than five years, as described below.
 
  Although the Board of Trustees believes that tender offers for the Shares
generally would increase the liquidity of the Shares, the repurchase of Shares
by the Fund will decrease the total assets of the Fund and, therefore, increase
the Fund's expense ratio. Because of the nature of the Fund's portfolio, the
Adviser anticipates potential difficulty in disposing of portfolio securities in
order to consummate tender offers for the Shares. As a result, the Fund may be
required to borrow money in order to finance repurchases.
 
  Even if a tender offer has been made, the Trustees' announced policy, which
may be changed by the Trustees, is that the Fund cannot accept tenders if (1) in
the reasonable judgment of the Trustees, there is not sufficient liquidity of
the assets of the Fund; (2) such transactions, if consummated, would (a) impair
the Fund's status as a regulated investment company under the Code (which would
make the Fund a taxable entity, causing the Fund's taxable income to be taxed at
the Fund level, as more fully described in "Taxation") or (b) result in a
failure to comply with applicable asset coverage requirements; or (3) there is,
in the Board of Trustees' reasonable judgment, any (a) material legal action or
proceeding instituted or threatened challenging such transactions or otherwise
materially adversely affecting the Fund, (b) suspension of or limitation on
prices for trading securities generally on any United States national securities
exchange or in the over-the-counter market, (c) declaration of a banking
moratorium by federal or state authorities or any suspension of payment by banks
in the United States or New York State, (d) limitation affecting the Fund or the
issuers of its portfolio securities imposed by federal or state authorities on
the extension of credit by lending institutions, (e) commencement of war, armed
hostilities or other international or national calamity directly or indirectly
involving the United States or (f) other event or
 
                                       21

condition which would have a material adverse effect on the Fund or the holders
of its Shares if Shares were repurchased. The Trustees may modify these
conditions in light of experience. Any tender offer made by the Fund for its
Shares will be at a price equal to the net asset value of the Shares determined
at the close of business on the day the offer ends.
 
  The Fund's Declaration of Trust authorizes the Fund, without prior approval of
the holders of Shares, to borrow money in an amount up to 33 1/3% of the Fund's
total assets, for the purpose of, among other things, obtaining short-term
credits in connection with tender offers by the Fund for Shares. In this
connection, the Fund may issue notes or other evidence of indebtedness or secure
any such borrowings by mortgaging, pledging or otherwise subjecting as security
the Fund's assets. Under the requirements of the 1940 Act, the Fund, immediately
after any such borrowing, must have an "asset coverage" of at least 300%. With
respect to any such borrowing, asset coverage means the ratio which the value of
the total assets of the Fund, less all liabilities and indebtedness not
represented by senior securities (as defined in the 1940 Act), bears to the
aggregate amount of such borrowing by the Fund. The rights of lenders to the
Fund to receive interest on and repayment of principal of any such borrowings
will be senior to those of the holders of Shares, and the terms of any such
borrowings may contain provisions which limit certain activities of the Fund,
including the payment of dividends to holders of Shares in certain
circumstances. Further, the terms of any such borrowing may and the 1940 Act
does (in certain circumstances) grant to the lenders to the Fund certain voting
rights in the event of default in the payment of interest on or repayment of
principal. In the event that such provisions would impair the Fund's status as a
regulated investment company, the Fund, subject to its ability to liquidate its
relatively illiquid portfolio, intends to repay the borrowings. Any borrowing
will likely rank senior to or pari passu with all other existing and future
borrowings of the Fund. Interest payments and fees incurred in connection with
borrowings will reduce the amount of net income available for payment to the
holders of Shares. The Fund does not intend to use borrowings for long-term
financial leverage purposes. Accordingly, the Fund will not purchase additional
portfolio securities at any time that borrowings, including the Fund's
commitments, pursuant to reverse repurchase agreements, exceed 5% of the Fund's
total assets (after giving effect to the amount borrowed).
 
   
  The Fund may from time to time enter into one or more credit agreements to
provide the Fund with additional liquidity to meet its obligations to purchase
Common Shares pursuant to any tender offer it may make. The Fund has currently
entered into a Credit Agreement dated April 17, 1997, as amended and restated on
April 16, 1998 (the "Credit Agreement") among the Fund, as borrower, the banks
thereto (the "Financial Institutions"), and Bank of America National Trust and
Savings Association ("BofA"), as agent, pursuant to which the Financial
Institutions have committed to provide a credit facility of up to $500,000,000
to the Fund, which is not secured by the assets of the Fund or other collateral.
As of the date of this Prospectus, the Fund has not borrowed any amounts
available under the Credit Agreement which will terminate by its terms on April
15, 1999, unless extended by its terms. The Fund is currently evaluating
alternative credit arrangements to provide additional liquidity for tender
offers.
    
 
  Should the Fund determine to make a tender offer for its Shares, a notice
describing the tender offer, containing information shareholders should consider
in deciding whether to tender their Shares and including instructions on how to
tender Shares will be sent to shareholders of record. Information concerning the
purchase price to be paid by the Fund and the manner in which shareholders may
ascertain net asset value during the pendency of a tender offer will also be set
forth in the notice. The Fund will purchase Shares tendered in accordance with
the terms of the offer unless it determines to terminate the offer. Costs
associated with the tender will be charged against capital. See the Statement of
Additional Information for additional information concerning repurchase of
Shares.
 
  Upon the death of a holder of Shares, VKF will waive any early withdrawal
charge (discussed below) applicable to the first $100,000 worth of such holder's
Shares repurchased pursuant to a tender offer commenced within one year of such
holder's death; provided that the Fund's transfer agent has received, on VKF's
behalf, proper notice of the death of such holder. For this purpose, the
transfer agent will be deemed to have received proper notice of such holder's
death upon its receipt of (i) a duly executed Letter of Transmittal duly
submitted in connection with a tender offer, (ii) a written request for waiver
of the early withdrawal charge, in form satisfactory to the transfer agent,
signed by the holder's duly authorized representative or surviving tenant, (iii)
appropriate evidence of death and (iv) appropriate evidence of the authority of
the representative of the deceased holder or surviving tenant. Shares held in
joint tenancy or tenancy in common will be deemed to be held by a single holder
(which may be either tenant in the case of joint tenancy) and the death of any
such tenant will be deemed to be the death of such holder of Shares. Information
concerning the waiver of the early withdrawal charge may be obtained by
contacting the Fund.

  EARLY WITHDRAWAL CHARGE.  An early withdrawal charge designed to recover
offering expenses will be charged in connection with most Shares held for less
than five years which are accepted by the Fund for repurchase pursuant to tender
offers. The early withdrawal charge will be imposed on a number of Shares
accepted for cash tender from a record holder of Shares the value of which
exceeds the aggregate value at the time the tender is accepted of (a) all Shares
owned by such holder that were purchased more than five years prior to such
acceptance, (b) all Shares owned by such holder that were acquired through
reinvestment of distributions, and (c) the increase, if any, of value of all
other Shares owned by such holder (namely those purchased within the five years
preceding the acceptance) over the purchase price of such Shares. The early
withdrawal charge will be paid to VKF. For the fiscal years ended July 31, 1996,
1997 and 1998, VKF received payments totalling $5,721,300, $9,075,812 and
$16,169,200, respectively, pursuant to the early withdrawal charge. In
determining whether an early withdrawal charge is payable, it is assumed that
the acceptance of a repurchase offer would be made from the earliest purchase of
Shares. Any early withdrawal charge which is required to be imposed will be made
in accordance with the following schedule.

  EXCHANGES. Tendering shareholders may elect to receive, in lieu of cash, the
proceeds from the tender of Shares of the Fund in contingent deferred sales
charge shares ("Class B Shares") of certain open-end investment companies ("VK
Funds") distributed by VKF. The Early Withdrawal Charge will be waived for
Shares tendered in exchange for Class B Shares in the VK Funds; however, such
Class B Shares immediately become subject to a contingent deferred sales charge
schedule equivalent to the Early Withdrawal Charge schedule on Shares of the
Fund. Thus, shares of such VK Funds may be subject to a contingent deferred
sales charge upon a subsequent redemption from the VK Funds. The purchase of
shares of such VK Fund will be deemed to have occurred at the time of the
initial purchase of the Shares of the Fund for calculating the applicable
contingent deferred sales charge.
    
 
  The prospectus for each VK Fund describes its investment objectives and
policies. Shareholders can obtain, without charge, a prospectus by calling
1-800-341-2911 and should consider these objectives and policies carefully
before requesting an exchange. Each exchange must involve proceeds from Shares
which have a net asset value of at least $500. An exchange is a taxable event
and may result in a taxable gain or loss.
- --------------------------------------------------------------------------------
DESCRIPTION OF COMMON SHARES
- --------------------------------------------------------------------------------
 
  The Fund is an unincorporated business trust established under the laws of the
Commonwealth of Massachusetts by a Declaration of Trust dated July 14, 1989, as
amended to the date hereof (the "Declaration of Trust"). The Declaration of
Trust provides that the Trustees of the Fund may authorize separate classes of
shares of beneficial interest. The Trustees have authorized an unlimited number
of Shares. The Declaration of Trust also authorizes the Fund to borrow money or
otherwise obtain credit and in this connection issue notes or other evidence of
indebtedness. The Fund does not intend to hold annual meetings of the holders of
Shares.
 
  COMMON SHARES. The Declaration of Trust permits the Fund to issue an unlimited
number of full and fractional common shares of beneficial interest, $.01 par
value per common share. Each Share represents an equal proportionate interest in
the assets of the Fund with each other Share in the Fund. Holders of Shares will
be entitled to the payment of dividends when, as and if declared by the Board of
Trustees. The terms of any borrowings may limit the payment of dividends to the
holders of Shares. Each whole Share shall be entitled to one vote as to matters
on which it is entitled to vote pursuant to the terms of the Fund's Declaration
of Trust on file with the SEC. Upon liquidation of the Fund, after paying or
adequately providing for the payment of all liabilities of the Fund, and upon
receipt of such releases, indemnities and refunding agreements as they deem
necessary for their protection, the Trustees may distribute the remaining assets
of the Fund among the holders of the Shares. The Declaration of Trust provides
that shareholders are not liable for any liabilities of the Fund, requires
inclusion of a clause to that effect in every agreement entered into by the Fund
and
 
                                       23
<PAGE>   27
 
indemnifies shareholders against any such liability. Although shareholders of an
unincorporated business trust established under Massachusetts law, in certain
limited circumstances, may be held personally liable for the obligations of the
trust as though they were general partners, the provisions of the Declaration of
Trust described in the foregoing sentence make the likelihood of such personal
liability remote.
 
  As a rule, the Fund will not issue share certificates. However, upon written
request to the Fund's transfer agent, a share certificate will be issued for any
or all of the full Shares credited to an investor's account. Share certificates
which have been issued to an investor may be returned at any time.
 
  The Shares are not, and are not expected to be, listed for trading on any
national securities exchange nor, to the Fund's knowledge, is there, or is there
expected to be, any secondary trading market in the Shares. The following table
sets forth, since the commencement of the Fund's investment operations, for the
quarterly periods ending on the dates set forth below the high and low net asset
value per Share during such period.

  ANTI-TAKEOVER PROVISIONS IN THE DECLARATION OF TRUST. The Fund's Declaration
of Trust includes provisions that could have the effect of limiting the ability
of other entities or persons to acquire control of the Fund or to change the
composition of its Board of Trustees by discouraging a third party from seeking
to obtain control of the Fund. In addition, in the event a secondary market were
to develop in the Shares, such provisions could have the effect of depriving
holders of Shares of an opportunity to sell their Shares at a premium over
prevailing market prices.
 
  The Declaration of Trust requires the favorable vote of the holders of at
least two-thirds of the outstanding Shares then entitled to vote to approve,
adopt or authorize certain transactions with 5%-or-greater holders of Shares and
their associates, unless the Board of Trustees shall by resolution have approved
a memorandum of understanding with such holders, in which case normal voting
requirements would be in effect. For purposes of these provisions, a
5%-or-greater holder of Shares (a "Principal Shareholder") refers to any person
who, whether directly or indirectly and whether alone or together with its
affiliates and associates, beneficially owns 5% or more of the outstanding
Shares of the Fund. The transactions subject to these special approval
requirements are: (i) the merger or consolidation of the Fund or any subsidiary
of the Fund with or into any Principal Shareholder; (ii) the issuance of any
securities of the Fund to any Principal Shareholder for cash; (iii) the sale,
lease or exchange of all or any substantial part of the assets of the Fund to
any Principal Shareholder (except assets having an aggregate fair market value
of less than $1,000,000, aggregating for the purpose of such computation all
assets sold, leased or exchanged in any series of similar transactions within a
twelve-month period); or (iv) the sale, lease or exchange to the Fund or any
subsidiary thereof, in exchange for securities of the Fund, of any assets of any
Principal Shareholder (except assets having an aggregate fair market value of
less than $1,000,000, aggregating for the purposes of such computation all
assets sold, leased or exchanged in any series of similar transactions within a
twelve-month period).
 
  A Trustee may be removed from office (i) with cause by a written instrument
signed by at least two-thirds of the remaining Trustees or (ii) by a vote of the
holders of at least two-thirds of the Shares.
 
  The Board of Trustees has determined that the voting requirements described
above, which are greater than the minimum requirements under Massachusetts law
or the 1940 Act, are in the best interests of shareholders generally. Reference
should be made to the Declaration of Trust on file with the SEC for the full
text of these provisions.
- --------------------------------------------------------------------------------
PURCHASING SHARES OF THE FUND
- --------------------------------------------------------------------------------
 
  The Fund offers continuously its Shares through VKF, the principal
underwriter, whose offices are located at 1 Parkview Plaza, P.O. Box 5555,
Oakbrook Terrace, Illinois 60181-5555. The Shares will also be offered through
members of the National Association of Securities Dealers, Inc. ("NASD") or
eligible non-NASD members who are acting as brokers or agents for investors
("broker-dealers"). The Fund reserves the right to terminate or suspend the
continuous offering of its Shares at any time without prior notice.
 
  Except as discussed below under "Investments by Tax Sheltered Retirement
Plans," the minimum initial investment in the Fund is $1,000 and minimum
subsequent investment is $100.
 
  The Shares will be offered by the Fund at the public offering price next
computed after the Fund receives the order. Because the Fund determines the
public offering price once daily on each business day as of 5:00 p.m. Eastern
time, orders placed through an investor's broker-dealer must be transmitted to
the Fund by the broker-dealer prior to such time for the investor's order to be
executed at the public offering price to be determined that day. Any change in
price due to the failure of the Fund to receive an order prior to such time must
be settled between the investor and the broker-dealer placing the
 
                                       25
<PAGE>   29
 
order. The public offering price is equal to the net asset value per Share.
There will be no initial sales charge or underwriting discount on purchases of
Shares.
 
  VKF will compensate broker-dealers participating in the continuous offering at
a rate of 3.0% of the dollar value of Shares purchased from the Fund by such
broker-dealers. If the Shares remain outstanding after one year from the date of
their original purchase, VKF will compensate such broker-dealers at an annual
rate, paid quarterly, in an amount based on a percentage of the dollar value of
such Shares, in accordance with the following schedule:

At various times VKF may implement programs under which a broker-dealer's sales
force may be eligible to win nominal awards for certain sales efforts. The value
of any such non-cash awards will not exceed $50 per person annually. These
incentives will not change the price investors pay for Shares or the amount that
the Fund will receive from the sale of Shares. The compensation paid to
broker-dealers at the time of purchase and any quarterly payments mentioned
above will be paid by VKF out of its own assets, and not out of the assets of
the Fund. An early withdrawal charge payable to VKF will be imposed on most
Shares held for less than five years that are accepted for repurchase pursuant
to a tender offer by the Fund. See "Repurchase of Shares." The compensation paid
to broker-dealers and VKF, including the compensation paid at the time of
purchase, the quarterly payments mentioned above and the early withdrawal
charge, if any, will not in the aggregate exceed applicable limitations. VKF
will monitor the aggregate value of all such compensation on an ongoing basis.
 
  Automatic Investment. Once an investor has opened an account in the Fund with
the minimum $1,000 investment, the automatic investment option may be utilized
to make regular monthly investments of $100 or more into such investor's account
with the Fund. In order to utilize this option, an investor must fill out and
sign the Automatic Investment application available from the transfer agent, the
Fund, such investor's broker or dealer, or VKF. Once the transfer agent has
received this application, such investor's checking account at his designated
bank will be debited each month in the amount authorized by such investor to
purchase shares of the Fund. Once enrolled in the Automatic Investment Program,
an investor may change the monthly amount or terminate participation at any time
by writing the transfer agent. Investors in the automatic investment program
will receive a confirmation of these transactions from the Fund quarterly and
their regular bank account statements will show the debit transaction each
month.
 
  Investments by Tax-Sheltered Retirement Plans. Shares are available for
purchase in connection with certain types of tax-sheltered retirement plans.
Eligible investors may establish individual retirement accounts ("IRAs");
Employee Pension Plans ("SEP's"); other pension and profit sharing plans; 401(k)
plans; or Section 403(b)(7) plans. Documents and forms containing detailed
information regarding these plans are available from the Distributor. Van Kampen
Trust Company serves as custodian under the IRA, 403(b)(7) and Keogh plans.
 
  The purchase of Shares may be limited by the plans' provisions and does not
itself establish such plans. The minimum initial investment in connection with a
tax-sheltered retirement plan is $250.
 
  Shareholders considering establishing a retirement plan or purchasing any Fund
shares in connection with a retirement plan, should consult with their attorney
or tax advisor with respect to plan requirements and tax aspects pertaining to
the shareholder.
 
  The illiquid nature of the Shares may affect the nature of distributions from
tax sheltered retirement plans and may affect the ability of participants in
such plans to rollover assets to other tax sheltered retirement plans.

  The Fund will send semi-annual and annual reports to shareholders, including a
list of the portfolio investments held by the Fund.

  From time to time advertisements and other sales materials for the Fund may
include information concerning the historical performance of the Fund. Any such
information may include a distribution rate and an average compounded
distribution rate of the Fund for specified periods of time. Such information
may also include performance rankings and similar information from independent
organizations such as Lipper Analytical Services, Inc., Business Week, Forbes or
other industry publications.
 
  The Fund's distribution rate generally is determined on a monthly basis with
respect to the immediately preceding monthly distribution period. The
distribution rate is computed by first annualizing the Fund's distributions per
Share during such a monthly distribution period and dividing the annualized
distribution by the Fund's maximum offering price per Share on the last day of
such period. The Fund calculates the compounded distribution rate by adding one
to the monthly distribution rate, raising the sum to the power of 12 and
subtracting one from the product. In circumstances in which the Fund believes
that, as a result of decreases in market rates of interest, its expected monthly
distributions may be less than the distributions with respect to the immediately
preceding monthly distribution period, the Fund reserves the right to calculate
the distribution rate on the basis of a period of less than one month.
 
  When utilized by the Fund, distribution rate and compounded distribution rate
figures are based on historical performance and are not intended to indicate
future performance. Distribution rate, compounded distribution rate and net
asset value per share can be expected to fluctuate over time.
 
  The following table is intended to provide investors with a comparison of
short-term money market rates. This comparison should not be considered a
representation of future money market rates, nor what an investment in the Fund
may earn or what an investor's yield or total return may be in the future. These
comparisons may be used in advertisements and in information furnished to
present or prospective shareholders.

                                   APPENDIX A
 
MOODY'S INVESTORS SERVICE
 
  A brief description of the applicable Moody's Investors Service (Moody's)
rating symbols and their meanings (as published by Moody's Investor Service)
follows:
 
  Aaa: Bonds which are rated Aaa are judged to be of the best quality. They
carry the smallest degree of investment risk and are generally referred to as
"gilt edged." Interest payments are protected by a large or by an exceptionally
stable margin and principal is secure. While the various protective elements are
likely to change, such changes as can be visualized are most unlikely to impair
the fundamentally strong position of such issues.
 
  Aa: Bonds which are rated Aa are judged to be of high quality by all
standards. Together with the Aaa group they comprise what are generally known as
high grade bonds. They are rated lower than the best bonds because margins of
protection may not be as large as in Aaa securities or fluctuation of protective
elements may be of greater amplitude or there may be other elements present
which make the long-term risk appear somewhat larger than the Aaa securities.
 
  A: Bonds which are rated A possess many favorable investment attributes and
are to be considered as upper-medium-grade obligations. Factors giving security
to principal and interest are considered adequate, but elements may be present
which suggest a susceptibility to impairment some time in the future.
 
   
  Baa: Bonds which are rated Baa are considered as medium-grade obligations,
(i.e., they are neither highly protected nor poorly secured). Interest payments
and principal security appear adequate for the present but certain protective
elements may be lacking or may be characteristically unreliable over any great
length of time. Such bonds lack outstanding investment characteristics and in
fact have speculative characteristics as well.
    
 
  Ba: Bonds which are rated Ba are judged to have speculative elements; their
future cannot be considered as well-assured. Often the protection of interest
and principal payments may be very moderate, and thereby not well safeguarded
during both good and bad times over the future. Uncertainty of position
characterizes bonds in this class.
 
  B: Bonds which are rated B generally lack characteristics of the desirable
investment. Assurance of interest and principal payments or of maintenance of
other terms of the contract over any long period of time may be small.
 
  Caa: Bonds which are rated Caa are of poor standing. Such issues may be in
default or there may be present elements of danger with respect to principal or
interest.
 
  Ca: Bonds which are rated Ca represent obligations which are speculative in a
high degree. Such issues are often in default or have other marked shortcomings.
 
  C: Bonds which are rated C are the lowest rated class of bonds, and issues so
rated can be regarded as having extremely poor prospects of ever attaining any
real investment standing.
 
   
  Note: Moody's applies numerical modifiers 1, 2, and 3 in each generic rating
category from Aa to Caa in the corporate finance sectors, and from Aa to B in
the public finance sectors. The modifier 1 indicates that the issuer is in the
higher end of its letter rating category; the modifier 2 indicates a mid-range
ranking; and the modifier 3 indicates that the issuer is in the lower end of the
letter ranking category.
    
 
  ABSENCE OF RATING: Where no rating has been assigned or where a rating has
been suspended or withdrawn, it may be for reasons unrelated to the quality of
the issue.
 
  Should no rating be assigned, the reason may be one of the following:
 
        1. An application for rating was not received or accepted.
 
        2. The issue or issuer belongs to a group of securities or companies
           that are not rated as a matter of policy.
 
        3. There is a lack of essential data pertaining to the issue or issuer.
 
        4. The issue was privately placed, in which case the rating is not
           published in Moody's publications.
 
  Suspension or withdrawal may occur if new and material circumstances arise,
the effects of which preclude satisfactory analysis; if there is no longer
available reasonable up-to-date data to permit a judgment to be formed; if a
bond is called for redemption; or for other reasons.
                                       A-1
<PAGE>   34
 
  Moody's short-term debt ratings are opinions of the ability of issuers to
repay punctually senior debt obligations. These obligations have an original
maturity not exceeding one year unless explicitly noted.
 
  Moody's employs the following three designations, all judged to be investment
grade, to indicate the relative repayment ability of rated issues:
 
  Issuers rated Prime-1 (or supporting institutions) have a superior ability for
repayment of senior short-term debt obligations. Prime-1 repayment ability will
often be evidenced by many of the following characteristics:
 
        -- Leading market positions in well-established industries.
 
        -- High rates of return on funds employed.
 
        -- Conservative capitalization structure with moderate reliance on debt
           and ample asset protection.
 
        -- Broad margins is earnings coverage of fixed financial charges and
           high internal cash generation.
 
        -- Well-established access to a range of financial markets and assured
           sources of alternate liquidity.
 
  Issuers rated Prime-2 (or supporting institutions) have a strong ability for
repayment of senior short-term debt obligations. This will normally be evidenced
by many of the characteristics cited above but to a lesser degree. Earnings
trends and coverage ratios, while sound, may be more subject to variation.
Capitalization characteristics, while still appropriate, may be more affected by
external conditions. Ample alternate liquidity is maintained.
 
  Issuers rated Prime-3 (or supporting institutions) have an acceptable ability
for repayment of senior short-term obligations. The effect of industry
characteristics and market compositions may be more pronounced. Variability in
earnings and profitability may result in changes of the level of debt protection
measurements and may require relatively high financial leverage. Adequate
alternate liquidity is maintained.
 
  Issuers rated Not Prime do not fall within any of the Prime rating categories.
 
STANDARD & POOR'S
 
   
  A Standard & Poor's issue credit rating is a current opinion of the
creditworthiness of an obligor with respect to a specific financial obligation,
a specific class of financial obligations, or a specific financial program
(including ratings on medium term note programs and commercial paper programs).
It takes into consideration the creditworthiness of guarantors, insurers, or
other forms of credit enhancement on the obligation and takes into account the
currency in which the obligation is denominated. The issue credit rating is not
a recommendation to purchase, sell, or hold a financial obligation, inasmuch as
it does not comment as to market price or suitability for a particular investor.
    
 
   
  Issue credit ratings are based on current information furnished by the
obligors or obtained by Standard & Poor's from other sources it considers
reliable. Standard & Poor's does not perform an audit in connection with any
credit rating and may, on occasion, rely on unaudited financial information.
Credit ratings may be changed, suspended, or withdrawn as a result of changes
in, or unavailability of, such information, or based on other circumstances.
    
 
   
  Issue credit ratings can be either long-term or short-term. Short-term ratings
are generally assigned to those obligations considered short-term in the
relevant market. In the U.S., for example, that means obligations with an
original maturity of no more than 365 days -- including commercial paper.
Short-term ratings are also used to indicate the creditworthiness of an obligor
with respect to put features on long-term obligations. The result is a dual
rating, in which the short-term rating addresses the put feature, in addition to
the usual long-term rating. Medium-term notes are assigned long-term ratings.
    
 
   
LONG TERM ISSUE CREDIT RATINGS
    
 
   
  Issue credit ratings are based, in varying degrees, on the following
considerations:
    
 
   
  1. Likelihood of payment -- capacity and willingness of the obligor to meet
its financial commitment on an obligation in accordance with the terms of the
obligation;
    
 
   
  2. Nature of and provisions of the obligation;
    
 
                                       A-2
<PAGE>   35
 
   
  3. Protection afforded by, and relative position of, the obligation in the
event of bankruptcy, reorganization, or other arrangement under the laws of
bankruptcy and other laws affecting creditors' rights.
    
 
   
  The issue rating definitions are expressed in terms of default risk. As such,
they pertain to senior obligations of an entity. Junior obligations are
typically rated lower than senior obligations, to reflect the lower priority in
bankruptcy, as noted above. (Such differentiation applies when an entity has
both senior and subordinated obligations, secured and unsecured obligations, or
operating company and holding company obligations.) Accordingly, in the case of
junior debt, the rating may not conform exactly with the category definition.
    
 
   
  AAA: An obligation rated 'AAA' has the highest rating assigned by Standard &
Poor's. The obligor's capacity to meet its financial commitment on the
obligation is extremely strong.
    
 
   
  AA: An obligation rated 'AA' differs from the highest rated obligations only
in small degree. The obligor's capacity to meet its financial commitment on the
obligation is very strong.
    
 
   
  A: An obligation rated 'A' is somewhat more susceptible to the adverse effects
of changes in circumstances and economic conditions than obligations in higher
rated categories. However, the obligor's capacity to meet its financial
commitment on the obligation is still strong.
    
 
   
  BBB: An obligation rated 'BBB' exhibits ADEQUATE protection parameters.
However, adverse economic conditions or changing circumstances are more likely
to lead to a weakened capacity of the obligor to meet its financial commitment
on the obligation.
    
 
   
  Obligations rated 'BB', 'B', 'CCC', 'CC', and 'C' are regarded as having
significant speculative characteristics. 'BB' indicates the least degree of
speculation and 'C' the highest. While such obligations will likely have some
quality and protective characteristics, these may be outweighed by large
uncertainties or major exposures to adverse conditions.
    
 
   
  BB: An obligation rated 'BB' is LESS VULNERABLE to nonpayment than other
speculative issues. However, it faces major ongoing uncertainties or exposure to
adverse business, financial, or economic conditions which could lead to the
obligor's inadequate capacity to meet its financial commitment on the
obligation.
    
 
   
  B: An obligation rated 'B' is MORE VULNERABLE to nonpayment than obligations
rated 'BB', but the obligor currently has the capacity to meet its financial
commitment on the obligation. Adverse business, financial, or economic
conditions will likely impair the obligor's capacity or willingness to meet its
financial commitment on the obligation.
    
 
   
  CCC: An obligation rated 'CCC' is CURRENTLY VULNERABLE to nonpayment, and is
dependent upon favorable business, financial, and economic conditions for the
obligor to meet its financial commitment on the obligation. In the event of
adverse business, financial, or economic conditions, the obligor is not likely
to have the capacity to meet its financial commitment on the obligation.
    
 
   
  CC: An obligation rated 'CC' is currently HIGHLY VULNERABLE to nonpayment.
    
 
   
  C: A subordinated debt or preferred stock obligation rated 'C' is CURRENTLY
HIGHLY VULNERABLE to nonpayment. The 'C' rating may be used to cover a situation
where a bankruptcy petition has been filed or similar action taken, but payments
on this obligation are being continued. A 'C' also will be assigned to a
preferred stock issue in arrears on dividends or sinking fund payments, but that
is currently paying.
    
 
   
  D: An obligation rated 'D' is in payment default. The 'D' rating category is
used when payments on an obligation are not made on the date due even if the
applicable grace period has not expired, unless Standard & Poor's believes that
such payments will be made during such grace period. The 'D' rating also will be
used upon the filing of a bankruptcy petition or the taking of a similar action
if payments on an obligation are jeopardized.
    
 
   
  Plus (+) or minus (-) ratings from 'AA' to 'CCC' may be modified by the
addition of a plus or minus sign to show relative standing within the major
rating categories.
    
 
   
  r: This symbol is attached to the ratings of instruments with significant
noncredit risks. It highlights risks to principal or volatility of expected
returns which are not addressed in the credit rating. Examples include:
obligations linked or indexed to equities, currencies, or commodities;
obligations exposed to severe prepayment risk -- such as interest-only or
principal-only mortgage securities; and obligations with unusually risky
interest terms, such as inverse floaters.

  N.R.: This indicates that no rating has been requested, that there is
insufficient information on which to base a rating, or that Standard & Poor's
does not rate a particular obligation as a matter of policy.
    
 
   
SHORT-TERM ISSUE CREDIT RATINGS
    
 
   
  A-1: A short-term obligation rated 'A-1' is rated in the highest category by
Standard & Poor's. The obligor's capacity to meet its financial commitment on
the obligation is strong. Within this category, certain obligations are
designated with a plus sign (+). This indicates that the obligor's capacity to
meet its financial commitment on these obligations is extremely strong.
    
 
   
  A-2: A short-term obligation rated 'A-2' is somewhat more susceptible to the
adverse effects of changes in circumstances and economic conditions than
obligations in higher rating categories. However, the obligor's capacity to meet
its financial commitment on the obligation is satisfactory.
    
 
   
  A-3: A short-term obligation rated 'A-3' exhibits adequate protection
parameters. However, adverse economic conditions or changing circumstances are
more likely to lead to a weakened capacity of the obligor to meet its financial
commitment on the obligation.
    
 
   
  B: A short-term obligation rated 'B' is regarded as having significant
speculative characteristics. The obligor currently has the capacity to meet its
financial commitment on the obligation; however, it faces major ongoing
uncertainties which could lead to the obligor's inadequate capacity to meet its
financial commitment on the obligation.
    
 
   
  C: A short-term obligation rated 'C' is currently vulnerable to nonpayment and
is dependent upon favorable business, financial, and economic conditions for the
obligor to meet its financial commitment on the obligation.
    
 
   
  D: A short-term obligation rated 'D' is in payment default. The 'D' rating
category is used when payments on an obligation are not made on the date due
even if the applicable grace period has not expired, unless Standard & Poor's
believes that such payments will be made during such grace period. The 'D'
rating also will be used upon the filing of a bankruptcy petition or the taking
of a similar action if payments on an obligation are jeopardized.
    
 
   
LOCAL CURRENCY AND FOREIGN CURRENCY RISKS
    
 
   
  Country risk considerations are a standard part of Standard & Poor's analysis
for credit ratings on any issuer or issue. Currency of repayment is a key factor
in this analysis. An obligor's capacity to repay foreign currency obligations
may be lower than its capacity to repay obligations in its local currency due to
the sovereign government's own relatively lower capacity to repay external
versus domestic debt. These sovereign risk considerations are incorporated in
the debt ratings assigned to specific issues. Foreign currency issuer ratings
are also distinguished from local currency issuer ratings to identify those
instances where sovereign risks make them different for the same issuer.

                       INVESTMENT OBJECTIVE AND POLICIES
                        AND SPECIAL RISK CONSIDERATIONS
 
   
  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
through investment primarily in a professionally managed portfolio of interests
in floating or variable rate Senior Loans. Although the Fund's net asset value
will vary, the Fund's policy of acquiring interests in floating or variable rate
Senior Loans should minimize the fluctuations in the Fund's net asset value as a
result of changes in interest rates. The Fund's net asset value may be affected
by changes in the credit quality of Borrowers. An investment in the Fund may not
be appropriate for all investors and is not intended to be a complete investment
program. No assurance can be given that the Fund will achieve its investment
objective. For further discussion of the characteristics of Senior Loan
interests and the associated special risk considerations, see "Investment
Objective and Policies" and "Special Risk Considerations" in the Prospectus.
    
 
                            INVESTMENT RESTRICTIONS
 
  The Fund's investment objective and the following investment restrictions are
fundamental and cannot be changed without the approval of the holders of a
majority (defined as the lesser of (i) 67% or more of the voting securities
present at a meeting of shareholders, if the holders of more than 50% of the
outstanding voting securities are present or represented by proxy at such
meeting, or (ii) more than 50% of the outstanding voting securities) of the
Fund's outstanding Shares. All other investment policies or practices are
considered by the Fund not to be fundamental and accordingly may be changed
without shareholder approval. If a percentage restriction on investment or use
of assets set forth below is adhered to at the time a transaction is effected,
later changes in percentage resulting from changing market values will not be
considered a deviation from policy. In accordance with the foregoing, the Fund
may not:
 
   1. Purchase any securities (other than obligations issued or guaranteed by
      the United States Government or by its agencies or instrumentalities), if
      as a result more than 5% of the Fund's total assets would then be invested
      in securities of a single issuer or if as a result the Fund would hold
      more than 10% of the outstanding voting securities of any single issuer;
      provided that, with respect to 50% of the Fund's assets, the Fund may
      invest up to 25% of its assets in the securities of any one issuer. For
      purposes of this restriction, the term issuer includes both the Borrower
      under a Loan Agreement and the Lender selling a Participation to the Fund
      together with any other persons interpositioned between such Lender and
      the Fund with respect to a Participation.
 
   2. Purchase any security if, as a result of such purchase, more than 25% of
      the Fund's total assets (taken at current value) would be invested in the
      securities of Borrowers and other issuers having their principal business
      activities in the same industry (the electric, gas, water and telephone
      utility industries, commercial banks, thrift institutions and finance
      companies being treated as separate industries for purposes of this
      restriction); provided, that this limitation shall not apply with respect
      to obligations issued or guaranteed by the U.S. Government or by its
      agencies or instrumentalities.
 
   3. Issue senior securities (including borrowing money or entering into
      reverse repurchase agreements) in excess of 33 1/3% of its total assets
      (including the amount of senior securities issued but excluding any
      liabilities and indebtedness not constituting senior securities) except
      that the Fund may borrow up to an additional 5% of its total assets for
      temporary purposes, or pledge its assets other than to secure such
      issuance or in connection with hedging transactions, when-issued and
      delayed delivery transactions and similar investment strategies. The Fund
      will not purchase additional portfolio securities at any time that
      borrowings, including the Fund's commitments pursuant to reverse
      repurchase agreements, exceed 5% of the Fund's total assets (after giving
      effect to the amount borrowed).
 
   4. Make loans of money or property to any person, except for obtaining
      interests in Senior Loans in accordance with its investment objective,
      through loans of portfolio securities or the acquisition of securities
      subject to repurchase agreements.
 
                                       B-2
<PAGE>   41
 
   5. Buy any security "on margin." Neither the deposit of initial or variation
      margin in connection with hedging transactions nor short-term credits as
      may be necessary for the clearance of such transactions is considered the
      purchase of a security on margin.
 
   6. Sell any security "short," write, purchase or sell puts, calls or
      combinations thereof, or purchase or sell financial futures or options,
      except to the extent that the hedging transactions in which the Fund may
      engage would be deemed to be any of the foregoing transactions.
 
   7. Act as an underwriter of securities, except to the extent the Fund may be
      deemed to be an underwriter in connection with the sale of or granting of
      interests in Senior Loans or other securities acquired by the Fund.
 
   8. Make investments for the purpose of exercising control or participation in
      management, except to the extent that exercise by the Fund of its rights
      under Loan Agreements would be deemed to constitute such control or
      participation.
 
   9. Invest in securities of other investment companies, except as part of a
      merger, consolidation or other acquisitions. The Fund will rely on
      representations of Borrowers in Loan Agreements in determining whether
      such Borrowers are investment companies.
 
  10. Buy or sell oil, gas or other mineral leases, rights or royalty contracts
      except pursuant to the exercise by the Fund of its rights under Loan
      Agreements. In addition, the Fund may purchase securities of issuers which
      deal in, represent interests in or are secured by interests in such
      leases, rights or contracts.
 
  11. Purchase or sell real estate, commodities or commodities contracts except
      pursuant to the exercise by the Fund of its rights under Loan Agreements,
      except to the extent the interests in Senior Loans the Fund may invest in
      are considered to be interests in real estate, commodities or commodities
      contracts and except to the extent that hedging instruments the Fund may
      invest in are considered to be commodities or commodities contracts.
 
  12. Notwithstanding the investment policies and restrictions of the Fund, upon
      approval of the Board of Trustees, the Fund may invest all or part of its
      investable assets in a management investment company with substantially
      the same investment objective, policies and restrictions as the Fund.
 
  For purposes of investment restriction number 2, the Fund has adopted
supplementally a more restrictive non-fundamental investment policy that in
effect changes the phrase "more than 25%" to "25% or more." For purposes of
investment restriction number 2 and the supplement just described, the Fund will
consider all relevant factors in determining whether to treat the Lender selling
a Participation and any persons interpositioned between such Lender and the Fund
as an issuer, including: the terms of the Loan Agreement and other relevant
agreements (including inter-creditor agreements and any agreements between such
person and the Fund's custodian); the credit quality of such Lender or
interpositioned person; general economic conditions applicable to such Lender or
interpositioned person; and other factors relating to the degree of credit risk,
if any, of such Lender or interpositioned person incurred by the Fund.
 
  The Fund generally will not engage in the trading of securities for the
purpose of realizing short-term profits, but it will adjust its portfolio as it
deems advisable in view of prevailing or anticipated market conditions to
accomplish the Fund's investment objective. For example, the Fund may sell
portfolio securities in anticipation of a movement in interest rates. Frequency
of portfolio turnover will not be a limiting factor if the Fund considers it
advantageous to purchase or sell securities. The Fund anticipates that the
annual portfolio turnover rate of the Fund will not be in excess of 100%. A high
rate of portfolio turnover involves correspondingly greater expenses than a
lower rate, which expenses must be borne by the Fund and its shareholders.
 
  FUND STRUCTURE. The Fund's fundamental investment policies and restrictions
give the Fund the flexibility to pursue its investment objective through a fund
structure commonly known as a "master-feeder" structure. If the Fund converts to
a master-feeder structure, the existing shareholders of the Fund would continue
to hold their shares of the Fund and the Fund would become a feeder-fund of the
master-fund. The value of a shareholder's shares would be the same immediately
after any conversion as the value immediately before such conversion. Use of
this master-feeder structure potentially would result in increased assets
invested among the collective investment vehicle of which the Fund would be a
part, thus allowing operating expenses to be spread over a larger asset base,
potentially achieving economies of scale. The Fund's Board of Trustees presently
does not intend to affect any conversion of the Fund to a master-feeder
structure.

     *Such trustees are "interested persons" as defined in the 1940 Act.
     Messrs. McDonnell and Powell are interested persons of the Adviser and
     the Fund by reason of their positions at the Adviser. Mr. Whalen is an
     interested person of the Fund by reason of his law firm having acted
     as legal counsel to the Fund.
 
The officers and Trustees hold the same positions with other funds in the Fund
Complex. The officers and Trustees as a group own less than 1% of the Fund's
outstanding Shares. The compensation of the officers and trustees who are
affiliated persons (as defined in the 1940 Act) of the Adviser, VKF or Van
Kampen is paid by the respective entity. The Fund pays the compensation of all
other officers and trustees of the Fund. Funds in the Fund Complex, including
the Fund, pay the Trustees who are not affiliated persons of the Adviser, VKF or
Van Kampen, an annual Fund Complex retainer (generally equal to the product of
$2,500 times the number of funds in the Fund Complex), which retainer is then
allocated among funds in the Fund Complex based on their relative net assets,
and $250 per fund per meeting of the Board of Trustees, as well as reimbursement
of expenses incurred in connection with such meetings. Under the Fund's
retirement plan, trustees who are not affiliated with the Adviser, VKF or Van
Kampen, have at least ten years of service (including years of service prior to
adoption of the retirement plan) and retire at or after attaining the age of 60,
are eligible to receive a retirement benefit equal to $2,500 for each of the ten
years following such trustee's retirement. Under certain conditions, reduced
benefits are available for early retirement. Under the Fund's deferred
compensation plan, a trustee who is not affiliated with the Adviser, VKF or Van
Kampen, can elect to defer receipt of all or a portion of the trustee's fees
earned by such trustee until such trustee's retirement. The deferred
compensation earns a rate of return determined by reference to the Fund or other
funds in the Fund Complex as selected by the trustee. To the extent permitted by
the 1940 Act, the Fund may invest in securities of other funds in the Fund
Complex in order to match the deferred compensation obligation. The deferred
compensation plan is not funded and obligations thereunder represent general
unsecured claims against the general assets of the Fund. Subject to certain
exceptions and limitations, as fully described in Section 5.3 of the Fund's
Declaration of Trust on file with the SEC, the Fund indemnifies every Trustee
and officer of the Fund against liabilities and expenses reasonably incurred or
paid in connection with any claim, action, suit or proceeding in which he
becomes involved by virtue of his being or having been a Trustee or officer.
Such indemnification is unavailable for any Trustee or officer who is deemed to
have engaged in willful misfeasance, bad faith, gross negligence or reckless
disregard of his duties or to not have acted in good faith in the reasonable
belief that his action was in the best interest of the Fund.

(2)  The amounts shown in this column are the Aggregate Compensation of the Fund
     before deferral by the trustees under the deferred compensation plan during
     its last completed fiscal year ended July 31, 1998. The following trustees
     deferred all or a portion of their compensation from the Fund during the
     fiscal year ended July 31, 1998: Mr. Dammeyer $25,312; Mr. Sonnenschein
     $25,312; Mr. Kerr $2,507; and Mr. Whalen $25,299. The cumulative deferred

                                       B-7
<PAGE>   46
 
each trustee from the Fund as of July 31, 1998 is as follows: Mr. Dammeyer
$41,486; Mr. Sonnenschein $41,451; Mr. Kerr $16,044; and Mr. Whalen $36,604. The
deferred compensation plan is described above the table. Amounts deferred are
    retained by the Fund and earn a rate of return determined by reference to
    either the return on the Common Shares of the Fund or other funds in the
    Fund Complex as selected by the respective trustee. To the extent permitted
    by the 1940 Act, the Fund may invest in securities of these funds selected
    by the trustees in order to match the deferred compensation obligation.
 
   
(3)  The amounts shown in this column represent the sum of the estimated Pension
     or Retirement Benefit Accruals expected to be accrued by the 41 operating
     investment companies in the Fund Complex as of December 31, 1998 for their
     respective fiscal year ends in 1998. The retirement plan is described above
     the table.
    
 
   
(4)  The amounts shown in this column represent the sum of the estimated annual
     benefits payable per year by the 41 operating investment companies in the
     Fund Complex as of December 31, 1998 for each year of the 10-year period
     commencing in the year of such trustee's anticipated retirement. The Fund
     is expected to pay benefits of $2,500 per year for each of the 10-year
     period commencing in the year of such trustee's retirement to those
     trustees who retire at or over the age of 60 and with at least ten years of
     service to the Fund. The retirement plan is described above the
     compensation table.
    
 
   
(5)  The amounts shown in this column are accumulated from the Aggregate
     Compensation of the 41 investment companies in the Fund Complex for the
     year ended December 31, 1998 before deferral by the trustees under the
     deferred compensation plan. Amounts deferred are retained by the respective
     fund and earn a rate of return determined by reference to either the return
     on the Common Shares of the Fund or common shares of other funds in the
     Fund Complex as selected by the respective trustee. To the extent permitted
     by the 1940 Act, the respective fund may invest in securities of the funds
     selected by the trustees in order to match the deferred compensation
     obligation. The Adviser also serves as investment adviser for other
     investment companies; however, with the exception of Messrs. McDonnell,
     Powell and Whalen, the Trustees are not trustees of other investment
     companies. Combining the Fund Complex with other investment companies
     advised by the Adviser or its affiliates, Mr. Whalen received Total
     Compensation of $285,825 for the year ended December 31, 1998.
    
 
                             PORTFOLIO TRANSACTIONS
 
   
  With respect to interests in Senior Loans, the Fund generally will engage in
privately negotiated transactions for purchase or sale in which the Adviser will
negotiate on behalf of the Fund, although a more developed market may exist for
certain Senior Loans. The Fund may be required to pay fees, or forgo a portion
of interest and any fees payable to the Fund, to the Lender selling
Participations or Assignments to the Fund. The Adviser will determine the
Lenders from whom the Fund will purchase Assignments and Participations by
considering their professional ability, level of service, relationship with the
Borrower, financial condition, credit standards and quality of management.
Although the Fund intends generally to hold interests in Senior Loans until
maturity or prepayment of the Senior Loan, the illiquidity of many Senior Loans
may restrict the ability of the Adviser to locate in a timely manner persons
willing to purchase the Fund's interests in Senior Loans at a fair price should
the Fund desire to sell such interests. See "Special Risk Considerations" in the
Prospectus. Affiliates of the Adviser may participate in the primary and
secondary market for Senior Loans. Because of certain limitations imposed by the
1940 Act, this may restrict the Fund's ability to acquire some Senior Loans. The
Adviser does not believe that this will have a material effect on the Fund's
ability to acquire Senior Loans consistent with its investment policies.
    
 
  With respect to investments other than in Senior Loans, the Adviser will place
orders for portfolio transactions for the Fund with broker-dealer firms giving
consideration to the quality, quantity and nature of each firm's professional
services. These services include execution, clearance procedures, wire service
quotations and statistical and other research information provided to the Fund
and the Adviser, including quotations necessary to determine the value of the
Fund's net assets. Any research benefits so obtained are available for all
clients of the Adviser. Because statistical and other research information only
supplements the research efforts of the Adviser and still must be analyzed and
reviewed by its staff, the receipt of research information is not expected to
reduce materially its expenses. In selecting among the firms believed to meet
the criteria for handling a particular transaction, the Adviser may take into
consideration the fact that certain
                                       B-8
<PAGE>   47
 
firms have sold Shares of the Fund and that certain firms provide market,
statistical or other research information to the Fund and the Adviser and may
select firms that are affiliated with the Fund, the Adviser, VKF or Van Kampen.
For the fiscal years ended July 31, 1996, 1997 and 1998, the Fund paid brokerage
commissions of $179,000, $51,563 and $0, respectively.
 
  If it is believed to be in the best interest of the Fund, the Adviser may
place portfolio transactions with brokers who provide the types of services
described above, even if the Fund will have to pay a higher commission (or, if
the broker's profit is part of the cost of the security, will have to pay a
higher price for the security) than would be the case if the Adviser did not
consider the broker's furnishing of such services. This will be done, however,
only if, in the opinion of the Adviser, the amount of additional commission or
increased cost is reasonable in relation to the value of the services.
 
  If purchases or sales of financial instruments for the Fund and for one or
more other investment companies or clients advised by the Adviser are considered
at or about the same time, transactions in such financial instruments will be
allocated among the several investment companies and clients, in a manner deemed
equitable by the Adviser, to each such investment company or client, taking into
account their respective sizes and the aggregate amount of financial instruments
to be purchased or sold. In this regard allocations of Senior Loans by the
Adviser will be made taking into account a variety of factors, including the
assets of such clients then available for investment in Senior Loans, such
clients' relative net asset value and such clients' investment objectives,
policies and limitations. Although in some cases this procedure could have a
detrimental effect on the price paid by the Fund for the financial instrument or
the volume of the financial instrument purchased by the Fund, the ability to
participate in volume transactions and to negotiate lower commissions, fees and
expenses possibly could benefit the Fund.
 
  Although the Adviser will be responsible for the management of the Fund's
portfolio, the policies and practices in this regard must be consistent with the
foregoing and will be subject at all times to review by the Trustees of the
Fund. The Fund anticipates that the annual portfolio turnover rate will not
exceed 100%.
 
  The Trustees have adopted certain policies incorporating the standards of Rule
17e-1 issued by the SEC under the 1940 Act, which requires that the commissions
paid to affiliates of the Fund, or to affiliates of such persons, be reasonable
and fair compared to the commissions, fees or other remuneration received or to
be received by other brokers in connection with comparable transactions
involving similar financial instruments during a comparable period of time. The
rule and procedures also contain review requirements and require the Adviser to
furnish reports to the Trustees and to maintain records in connection with such
reviews. After review of all factors deemed relevant, the Trustees will consider
from time to time whether the advisory fee will be reduced by all or a portion
of the brokerage commissions given to brokers that are affiliated with the Fund.

year to year, unless earlier terminated as described below, if approved annually
(a) by the Trustees of the Fund or by a majority of the Fund's Shares and (b) by
a majority of the Trustees who are not parties to the agreement or interested
persons of any such party, in compliance with the requirements of the 1940 Act.
The Advisory Agreement may be terminated without penalty upon 60 days written
notice by either party (in the case of the Fund, such termination may be
effected by the Board of Trustees or by a majority of the Shares) and will
automatically terminate in the event of assignment. The Adviser may in its sole
discretion from time to time waive all or a portion of the advisory fee or
reimburse the Fund for all or a portion of its other expenses.
 
  The investment advisory agreement (the "Advisory Agreement") between the
Adviser and the Fund provides that the Adviser will supply investment research
and portfolio management, including the selection of securities for the Fund to
purchase, hold or sell and the selection of financial institutions through whom
the Fund's portfolio transactions are executed. The Adviser also furnishes
necessary facilities and equipment, and permits its officers and employees to

to such positions. For the fiscal years ended July 31, 1996, 1997 and 1998, the

error of judgment or of law, or for any loss suffered by the Fund in connection
with the matters to which the Advisory Agreement relates, except a loss
resulting from willful misfeasance, bad faith or gross negligence on the part of
the Adviser in the performance of its obligations and duties, or by reason of
its reckless disregard of its obligations and duties under the Advisory
Agreement.
 
   
  The Trustees are responsible for the overall management and supervision of the
Fund's affairs. The Adviser's activities are subject to the review and
supervision of the Trustees to whom the Adviser renders periodic reports of the
Fund's investment activities. The Advisory Agreement continues in effect from
year to year only if specifically approved by the Trustees, and by the
disinterested Trustees, or the Fund's holders of Shares in compliance with the
requirements of the 1940 Act. The Advisory Agreement may be terminated without
penalty upon 60 days' written notice by either party and will terminate
automatically in the event of assignment.

                           DIVIDEND REINVESTMENT PLAN
 
  The Fund offers a Dividend Reinvestment Plan (the "Plan"). Under the Plan
Shareholders may elect to have all distributions of dividends and capital gains
automatically reinvested in additional Shares. Unless you elect to participate
in the Plan, you will receive distributions in cash.
 
  State Street Bank and Trust Company, as plan agent (the "Plan Agent"), serves
as agent for Shareholders in administering the Plan. Participants in the Plan
will receive Shares valued on the valuation date, at net asset value. The
valuation date will be the dividend or distribution payment date or, if that
date is not a business day, the next preceding business day.
 
  The Plan Agent maintains each Shareholder's account in the Plan and furnishes
monthly written confirmations of all transactions in the accounts, including
information needed by Shareholders for personal and tax records. Shares will be
held by the Plan Agent in non-certificated form in the name of the participant,
and each Shareholder's proxy will include those Shares purchased pursuant to the
Plan. The Plan Agent's fees for the handling of the reinvestment of dividends
and distributions will be paid by the Fund.
 
  In the case of Shareholders, such as banks, brokers or nominees, which hold
Shares for others who are the beneficial owners, the Plan Agent will administer
the Plan on the basis of the number of Shares certified from time to time by the
record Shareholders as representing the total amount registered in the record
Shareholder's name and held for the account of beneficial owners who are
participating in the Plan.
 
  The automatic reinvestment of dividends and distributions will not relieve
participants of any federal income tax that may be payable or required to be
withheld on such dividends or distributions.
 
  Experience under the Plan may indicate that changes are desirable.
Accordingly, the Fund reserves the right to amend or terminate the Plan as
applied to any dividend or distribution paid subsequent to written notice of the
change sent to all Shareholders of the Fund at least 90 days before the record
date for the dividend distribution. The Plan also may be amended or terminated
by the Plan Agent by at least 90 days written notice to all Shareholders of the
Fund.
 
  All registered Shareholders (other than brokers or nominees) will be mailed
information regarding the Plan, including a form with which they may elect to
participate in the Plan. Shareholders who intend to hold their Shares through a
broker or nominee should contact such person to confirm that they may
participate in the Plan and to determine the effect, if any, that a transfer of
the account by the shareholder to another broker or nominee will have on
continued participation in the Plan. A Shareholder may withdraw from the Plan at
 
                                      B-11
<PAGE>   50
 
any time by contacting the Plan Agent at the address or telephone number set
forth below. There is no penalty for non-participation in or withdrawal from the
Plan, and Shareholders who have previously withdrawn from the Plan may rejoin it
at any time. Changes in elections should be directed to the Plan Agent and
should include the name of the Fund and the Shareholder's name and address as
registered. An election to withdraw from the Plan will, until such election is
changed, be deemed to be an election by a Shareholder to take all subsequent
dividends and distributions in cash. Elections will only be effective for
dividends and distributions declared after, and with a record date of at least
ten days after, such elections are received by the Plan Agent. When a
participant withdraws from the Plan or upon termination of the Plan as provided
above, certificates for whole Shares credited to his or her account under the
Plan will be issued and a cash payment will be made for any fraction of a Share
credited to such account. All correspondence concerning the dividend
reinvestment plan should be directed to the State Street Bank and Trust Company,
as Plan Agent, c/o Van Kampen Investor Services Inc., P.O. Box 418256, Kansas
City, MO 64153-9256. Please call (800) 341-2911 between the hours of 7:00 a.m.
and 7:00 p.m. Central Standard Time if you have questions regarding the Plan.
 
                                NET ASSET VALUE
 
  The net asset value per share of the Fund's Shares is determined by
calculating the total value of the Fund's assets, deducting its total
liabilities, and dividing the result by the number of Shares outstanding. The
net asset value will be computed on each business day as of 5:00 p.m. Eastern
time. The Fund reserves the right to calculate the net asset value more
frequently if deemed desirable.
 
  The value of the Fund's portfolio will be determined by the Adviser, following
guidelines established and periodically reviewed by the Trustees. Interests in
Senior Loans will be valued by the Adviser on behalf of the Fund on the basis of
market quotations and transactions in instruments which the Adviser believes may
be comparable to Senior Loan interests with respect to the following
characteristics: credit quality, interest rate, interest rate redetermination
period and maturity. Such instruments may include commercial paper, negotiable
certificates of deposit and short-term variable rate securities which have
adjustment periods comparable to the Senior Loan interests in the Fund's
portfolio. In determining the relationship between such instruments and the
Senior Loan interests in the Fund's portfolio, the Adviser will consider on an
ongoing basis, among other factors, (i) the credit worthiness of the Borrower
and (ii) the current interest rate, the period until next interest rate
redetermination and maturity of such Senior Loan interests. It is expected that
the Fund's net asset value will fluctuate as a function of interest rate and
credit factors. Because of the short-term nature of such instruments, however,
the Fund's net asset value is expected to fluctuate less in response to changes
in interest rates than the net asset values of investment companies with
portfolios consisting primarily of fixed-income or longer term securities. The
Adviser believes that Lenders selling Senior Loan interests or otherwise
involved in a Senior Loan transaction may tend, in valuing Senior Loan interests
for their own account, to be less sensitive to interest rate and credit quality
changes and, accordingly, the Adviser does not intend to rely solely on such
valuations in valuing the Senior Loan interests for the Fund's account. In
addition, because a secondary trading market in Senior Loans has not yet fully
developed, in valuing Senior Loans, the Adviser may not rely solely on but may
consider, to the extent the Adviser believes such information to be reliable,
prices or quotations provided by banks, dealers or pricing services with respect
to secondary market transactions in Senior Loans. To the extent that an active
secondary market in Senior Loan interests develops to a reliable degree, the
Adviser may rely to an increasing extent on such market prices and quotations in
valuing the Senior Loan interests in the Fund's portfolio. In light of the
senior nature of Senior Loan interests included in the Fund's portfolio and
taking into account the Fund's access to non-public information with respect to
Borrowers relating to such Senior Loan interests, the Adviser does not currently
believe that consideration on a systematic basis of ratings provided by any
nationally recognized statistical rating organization or price fluctuations with
respect to long- or short-term debt of such Borrowers subordinate to the Senior
Loans of such Borrowers is necessary for the determination of the value of such
Senior Loan interests. Accordingly, the Adviser generally does not
systematically consider (but may consider in certain instances) and, in any
event, does not rely upon such ratings or price fluctuations in determining the
value of Senior Loan interests in the Fund's portfolio.
 
                                      B-12
<PAGE>   51
 
  Other portfolio securities (other than short-term obligations, but including
listed issues) may be valued on the basis of prices furnished by one or more
pricing services which determine prices for normal, institutional-size trading
units of such securities using market information, transactions for comparable
securities and various relationships between securities which are generally
recognized by institutional traders. In certain circumstances, portfolio
securities will be valued at the last sale price on the exchange that is the
primary market for such securities, or the last quoted bid price for those
securities for which the over-the-counter market is the primary market or for
listed securities in which there were no sales during the day. The value of
interest rate swaps will be determined in accordance with a discounted present
value formula and then confirmed by obtaining a bank quotation.
 
  Short-term obligations which mature in 60 days or less are valued at amortized
cost, if their original term to maturity when acquired by the Fund was 60 days
or less, or are valued at amortized cost using their value on the 61st day prior
to maturity, if their original term to maturity when acquired by the Fund was
more than 60 days, unless in each case this is determined not to represent fair
value. Repurchase agreements will be valued at cost plus accrued interest.
Securities for which there exist no price quotations or valuations and all other
assets are valued at fair value as determined in good faith by or on behalf of
the Trustees.
 
   
                                    TAXATION
    
 
FEDERAL INCOME TAXATION
 
  The Fund has qualified and intends to continue to qualify each year to be
treated as a regulated investment company under Subchapter M of the Code. To
qualify as a regulated investment company, the Fund must, among other things:
(a) derive at least 90% of its gross income from dividends, interest, payments
with respect to loans of securities and gains from the sale or other disposition
of securities or certain other related income; and (b) diversify its holdings so
that at the end of each quarter of the Fund's taxable year (i) at least 50% of
the value of the Fund's assets is represented by cash, U.S. government
securities, securities of other regulated investment companies, and other
securities which, with respect to any one issuer, do not represent more than 5%
of the value of the Fund's assets or more than 10% of the voting securities of
such issuer, and (ii) not more than 25% of the value of the Fund's assets is
invested in the securities of any one issuer (other than U.S. government
securities or the securities of other regulated investment companies).
 
  If the Fund so qualifies and distributes each year to its Shareholders at
least 90% of its net investment income (including among other things, interest
and net short-term capital gain, but not net capital gains, which are the excess
of net long-term capital gains over net short-term capital losses), in each
year, it will not be required to pay federal income taxes on any income
distributed to Shareholders. The Fund intends to distribute at least the minimum
amount of net investment income necessary to satisfy the 90% distribution
requirement. The Fund will not be subject to federal income tax on any net
capital gains distributed to Shareholders. As a Massachusetts business trust,
the Fund will not be subject to any excise or income taxes in Massachusetts as
long as it qualifies as a regulated investment company for federal income tax
purposes.
 
  In order to avoid a 4% excise tax, the Fund will be required to distribute, by
December 31 of each year, at least an amount equal to the sum of (a) 98% of its
ordinary income for such year and (b) 98% of its capital gain net income (which
generally is computed on the basis of the one-year period ending on October 31
of such year), plus any amounts that were not distributed in previous taxable
years. For purposes of the excise tax, any ordinary income or capital gain net
income retained by, and subject to federal income tax in the hands of, the Fund
will be treated as having been distributed.
 
  If the Fund failed to qualify as a regulated investment company or failed to
satisfy the 90% distribution requirement in any taxable year, the Fund would be
taxed as an ordinary corporation on its taxable income (even if such income was
distributed to its Shareholders) and all distributions out of earnings and
profits would be taxed to Shareholders as ordinary income. To qualify again as a
regulated investment company in a subsequent year, the Fund may be required to
pay an interest charge on 50% of its earnings and profits attributable to
non-regulated investment company years and would be required to distribute such
earnings and profits to Shareholders (less any interest charge). In addition, if
the Fund failed to qualify as a regulated investment company for its first
taxable year or, if immediately after qualifying as a regulated investment
company for any taxable year, it failed to qualify for a period greater than one
taxable year, the Fund would be
 
                                      B-13
<PAGE>   52
 
required to recognize any net built-in gains (the excess of aggregate gains,
including items of income, over aggregate losses that would have been realized
if it had been liquidated) in order to qualify as a regulated investment company
in a subsequent year.
 
  Some of the Fund's investment practices are subject to special provisions of
the Code that, among other things, may defer the use of certain losses of the
Fund and affect the holding period of the securities held by the Fund and the
character of the gains or losses realized by the Fund. These provisions may also
require the Fund to recognize income or gain without receiving cash with which
to make distributions in amounts necessary to satisfy the 90% distribution
requirement and the distribution requirements for avoiding income and excise
taxes. The Fund will monitor its transactions and may make certain tax elections
in order to mitigate the effect of these rules and prevent disqualification of
the Fund as a regulated investment company.
 
  Investments of the Fund in securities issued at a discount or providing for
deferred interest or payment of interest in kind are subject to special tax
rules that will affect the amount, timing and character of distributions to
Shareholders. For example, with respect to certain securities issued at a
discount, the Fund will be required to accrue as income each year a portion of
the discount and to distribute such income each year in order to maintain its
qualification as a regulated investment company and to avoid income and excise
taxes. In order to generate sufficient cash to make distributions necessary to
satisfy the 90% distribution requirement and to avoid income and excise taxes,
the Fund may have to dispose of securities that it would otherwise have
continued to hold.
 
  Income from investments in foreign securities received by the Fund may be
subject to income, withholding or other taxes imposed by foreign countries and
U.S. possessions. Such taxes will not be deductible or creditable by
shareholders. Tax conventions between certain countries and the United States
may reduce or eliminate such taxes.
 
DISTRIBUTIONS
 
  Distributions of the Fund's net investment income are taxable to Shareholders
as ordinary income, whether paid in cash or reinvested in additional Shares.
Distributions of the Fund's net capital gains ("capital gain dividends"), if
any, are taxable to Shareholders at the rates applicable to long-term capital
gains regardless of the length of time Shares of the Fund have been held by such
Shareholders. Distributions in excess of the Fund's earnings and profits will
first reduce the adjusted tax basis of a holder's Shares and, after such
adjusted tax basis is reduced to zero, will constitute capital gains to such
holder (assuming such Shares are held as a capital asset). For a summary of the
tax rates applicable to capital gains (including capital gain dividends), see
"Capital Gains Rate" below. It is not expected that any portion of the
distributions from the Fund will be eligible for the dividends received
deduction for corporations. The Fund will inform Shareholders of the source and
tax status of all distributions promptly after the close of each calendar year.
 
  Shareholders receiving distributions in the form of additional Shares issued
by the Fund will be treated for federal income tax purposes as receiving a
distribution in an amount equal to the fair market value of the Shares received,
determined as of the distribution date. The basis of such Shares will equal the
fair market value of such shares on the distribution date.
 
  Although dividends generally will be treated as distributed when paid,
dividends declared in October, November or December, payable to Shareholders of
record on a specified date in such a month and paid during January of the
following year will be treated as having been distributed by the Fund and
received by the Shareholders on the December 31 prior to the date of payment. In
addition, certain other distributions made after the close of a taxable year of
the Fund may be "spilled back" and treated as paid by the Fund (except for
purposes of the 4% excise tax) during such taxable year. In such case,
Shareholders will be treated as having received such dividends in the taxable
year in which the distribution was actually made.
 
  The Fund is required, in certain circumstances, to withhold 31% of taxable
dividends and certain other payments, including redemptions, paid to
Shareholders who do not furnish to the Fund their correct taxpayer
identification number (in the case of individuals, their social security number)
and certain required certifications, or who are otherwise subject to backup
withholding. Foreign shareholders, including shareholders who are nonresident
aliens, may be subject to U.S. withholding tax on certain distributions (whether
received in cash or shares) at a rate of 30% or such lower rate as prescribed by
an applicable income tax treaty.
                                      B-14
<PAGE>   53
 
SALE OF SHARES
 
   
  Except as discussed below, selling Shareholders will generally recognize gain
or loss in an amount equal to the difference between their adjusted tax basis in
the Shares and the amount received. If such Shares are held as a capital asset,
the gain or loss will be a capital gain or loss. For a summary of the tax rates
applicable to capital gains, see "Capital Gains Rates" below. It is possible,
although the Fund believes it is unlikely, that, in connection with a tender
offer, distributions to tendering shareholders may be subject to tax as ordinary
income (rather than gain or loss), which in turn may result in deemed
distributions subject to tax as ordinary income for non-tendering shareholders.
The federal income tax consequences of repurchase of Shares pursuant to tender
offers will be disclosed in the related offering documents. Any loss recognized
upon a taxable disposition of Shares held for six months or less will be treated
as a long-term capital loss to the extent of any capital gains dividends
received with respect to such Shares. For purposes of determining whether Shares
have been held for six months or less, the holding period is suspended for any
periods during which the Shareholder's risk of loss is diminished as a result of
holding one or more other positions in substantially similar or related property
or through certain options or short sales.
    
 
CAPITAL GAINS RATES
 
   
  The maximum tax applicable to net capital gains recognized by individuals and
other non-corporate taxpayers is (i) the same as the maximum ordinary income tax
rate for capital assets held for one year or less or (ii) 20% for capital assets
held for more than one year. The maximum long-term capital gains rate for
corporations is 35%.
    
 
GENERAL
 
   
  The federal income tax discussion set forth above is for general information
only. Prospective investors should consult their advisers regarding the specific
federal tax consequences of purchasing, holding and disposing of Common Shares,
as well as the effects of state, local and foreign tax laws and any proposed tax
law changes.
    
 
                              REPURCHASE OF SHARES
 
   
  The Fund may from time to time enter into one or more credit agreements to
provide the Fund with additional liquidity to meet its obligations to purchase
Common Shares pursuant to any tender offer it may make. The Fund has currently
entered into a Credit Agreement dated April 17, 1997, as amended and restated on
April 16, 1998 (the "Credit Agreement") among the Fund, as borrower, the banks
thereto (the "Financial Institutions"), and Bank of America National Trust and
Savings Association ("BofA"), as agent, pursuant to which the Financial
Institutions have committed to provide a credit facility of up to $500,000,000
to the Fund, which is not secured by the assets of the Fund or other collateral.
As of the date of this Prospectus, the Fund has not borrowed any amounts
available under the Credit Agreement which will terminate by its terms on April
15, 1999, unless extended by its terms. The Fund is currently evaluating
alternative credit arrangements to provide additional liquidity for tender
offers. [The Credit Agreement has terms and conditions substantially similar to
the following:
    
 
  a. The Fund is entitled to borrow loans ("Loans") from the Financial
     Institutions amounts which in the aggregate do not exceed the lesser of (i)
     the $500 million credit facility each or (ii) twelve and one half percent
     (12.5%) of the net asset value of the Fund (defined as total assets minus
     total liabilities minus assets subject to liens).
 
  b. Loans made under the Credit Agreement, if any, will bear interest daily, at
     the Fund's option, (i) at a rate per annum equal to the federal funds rate
     from time to time plus 0.375%, provided, however, that during any period
     the aggregate outstanding loans exceed $250 million, the rate shall be the
     federal funds rate plus 0.50%, or (ii) at a rate per annum equal to a
     reserve-adjusted interbank offered rate offered by BofA's Grand Cayman
     Branch ("IBOR") plus 0.375% per annum, provided, however, that during any
     period the aggregate outstanding loans exceed $250 million, the rate shall
     be IBOR plus 0.50%. Such interest will be due on the outstanding principal
     amount (i) as to any federal funds rate loan on the last business day of
     each calendar quarter and (ii) as any offshore rate loan, from one (1)
 
                                      B-15
<PAGE>   54
 
     day to sixty (60) days from the date of the loan, as selected by the Fund
     in advance. Overdue payments of principal and interest will bear interest,
     payable upon demand, at a penalty rate. No Loan shall be outstanding for a
     period of more than sixty (60) days, and there shall be no more than three
     Interest Periods in effect in respect of an offshore rate loan.
 
  c. The Fund paid approximately $107,000 of fees and expenses to BofA or its
     affiliates on the date the Credit Agreement was executed. In addition,
     during the term of the Credit Agreement, the Fund is obligated to pay a
     commitment fee computed at the rate of 0.07% per annum on the average daily
     unused amount of the facility.
 
  d. The principal amount of loans made under the Credit Agreement, if any, are
     required to be paid sixty (60) days from the date of the loan. The Fund is
     entitled to prepay a loan in multiples of $1,000,000, provided that the
     Fund gives sufficient notices of prepayment. On the Commitment Termination
     Date (as defined below), all outstanding principal and accrued interest
     under the Credit Agreement will be due and payable in full.
 
  e. The drawdown of the initial Loan, if any, under the Credit Agreement is
     subject to certain conditions, including, among other things, the Fund
     executing and delivering a promissory note made payable to the order of
     each Financial Institution, in the form attached to the Credit Agreement
     (the "Promissory Notes").
 
     The drawdown of each Loan, if any, is further conditioned upon the
     satisfaction of additional conditions, including, without limitation, (i)
     the providing of notice with respect to the Loan, (ii) the Fund's asset
     coverage ratio must be at least 8 to 1; (iii) there being no default or
     event of default in existence; (iv) the representations and warranties made
     in the Credit Agreement continuing to be true and (v) there are no loans
     outstanding for more than sixty (60) days on the day preceding the proposed
     borrowing date.
 
  f.  The Credit Agreement contains various affirmative and negative covenants
      of the Fund, including, without limitation, obligations: (i) to provide
      periodic financial information; (ii) with limited exceptions, to not
      consolidate with or merge into any other entity or have any other entity
      merge into it and to not sell all or any substantial part of its assets;
      (iii) to continue to engage in its current type of business and to
      maintain its existence as a business trust; (iv) to comply with applicable
      laws, rules and regulations and perform its obligations under the Credit
      Agreement; (v) to maintain insurance on its property and business; (vi) to
      limit the amount of its debt based upon 12.5% of the net asset value of
      the Fund; and (vii) to not create any lien on any of its assets, with
      certain exceptions.
 
  g. The Credit Agreement also contains various events of default (with certain
     specified grace periods), including, without limitation: (i) failure to pay
     when due any amounts required to be paid to Financial Institutions under
     the Credit Agreement or the Promissory Notes; (ii) any material
     misrepresentations in the Credit Agreement or documents delivered to
     Financial Institutions; (iii) failure to observe or perform certain terms,
     covenants and agreements contained in the Credit Agreement, the Promissory
     Notes or other documents delivered to the Financial Institutions; (iv)
     failure to comply with the Fund's fundamental investment policies or
     investment restrictions; (v) failure to comply with all material provisions
     of the Investment Company Act of 1940; (vi) the voluntary or involuntary
     bankruptcy of the Fund; (vii) the entry of judgments for the payment of
     money in excess of $5,000,000 in the aggregate which remains unsatisfied or
     unstayed for a period of 30 days; and (viii) a change in control of the
     Fund's investment adviser.
 
  h. The credit facility provided pursuant to the Credit Agreement will
     terminate on April 16, 1999 (the "Commitment Termination Date"), unless
     extended pursuant to the terms thereof, and all accrued interest and
     principal will be due thereon.
 
   
  The Fund intends to repay any loans under the Credit Agreement from proceeds
from the specified pay-downs from the interests in Senior Loans (as defined
below) which will be acquired and from proceeds from the sale of Shares.]
    
 
                                      B-16
<PAGE>   55
 
  During the pendency of any tender offer by the Fund, the Fund will calculate
daily the net asset value of the Shares and will establish procedures which will
be specified in the tender offer documents, to enable Shareholders to ascertain
readily such net asset value. The relative illiquidity of some of the Fund's
portfolio securities could adversely impact the Fund's ability to calculate net
asset value in connection with determinations of pricing for tender offers, if
any. Each offer will be made and Shareholders notified in accordance with the
requirements of the Securities Exchange Act of 1934, as amended, and the 1940
Act, either by publication or mailing or both. Each offering document will
contain such information as is prescribed by such laws and the rules and
regulations promulgated thereunder.
 
  Tendered Shares that have been accepted and repurchased by the Fund will be
held in treasury and may be retired by the Board of Trustees. Treasury Shares
will be recorded and reported as an offset to Shareholders' equity and
accordingly will reduce the Fund's total assets. If Treasury Shares are retired,
Shares issued and outstanding and capital in excess of par value will be reduced
accordingly.
 
  If the Fund must liquidate portfolio securities in order to repurchase Shares
tendered, the Fund may realize gains and losses.

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.
 
(a) This Senior Loan interest is non-income producing.
 
(b) This Borrower has filed for protection in federal bankruptcy court.
 
(c) Restricted security.
 
(d) Non-income producing security as this stock currently does not declare
dividends.
 
 *  Senior Loans in the Trust'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 Trust's portfolio may occur. As a
    result, the actual remaining maturity of Senior Loans held in the Trust's
    portfolio may be substantially less than the stated maturities shown.
    Although the Trust is unable to accurately estimate the actual remaining
    maturity of individual Senior Loans, the Trust 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 Trust 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 Trust 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 Prime Rate Income Trust (the "Trust") is registered as a
non-diversified closed-end management investment company under the Investment
Company Act of 1940, as amended. The Trust's investment objective is to provide
a high level of current income, consistent with preservation of capital. The
Trust seeks to achieve its objective by investing primarily in a portfolio of
interests in floating or variable rate senior loans to United States
corporations, partnerships and other entities. The Trust commenced investment
operations on October 4, 1989.

    The following is a summary of significant accounting policies consistently
followed by the Trust 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 value of the Trust's Variable Rate Senior Loan
interests, totaling $6,738,765,358 (85.8% of net assets) is determined in the
absence of actual market values by Van Kampen Investment Advisory Corp. (the
"Adviser") following guidelines and procedures established, and periodically
reviewed, by the Board of Trustees. The value of a Variable Rate Senior Loan
interest in the Trust's portfolio is determined with reference to changes in
market interest rates and to the creditworthiness of the underlying obligor. In
valuing Variable Rate Senior Loan interests, the Adviser considers market
quotations and transactions in instruments that the Adviser believes may be
comparable to such Variable Rate Senior Loan interests. In determining the
relationship between such instruments and the Variable Rate Senior Loan
interests, the Adviser considers such factors as the creditworthiness of the
underlying obligor, the current interest rate, the interest rate redetermination
period and maturity date. To the extent that reliable market transactions in
Variable Rate Senior Loan interests have occurred, the Adviser also considers
pricing information derived from such secondary market transactions in valuing
Variable Rate Senior Loan interests. Because of uncertainty inherent in the
valuation process, the estimated value of a Variable Rate Senior Loan interest
may differ significantly from the value that would have been used had there been
market activity for that Variable Rate Senior Loan interest. Equity securities
are valued on the basis of prices furnished by

- --------------------------------------------------------------------------------
 
pricing services or as determined in good faith by the Adviser. Short-term
securities with remaining maturities of 60 days or less are valued at amortized
cost.
 
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 recognized as income ratably over the expected life of the
loan. Facility fees on senior loans purchased after July 31, 1997, are treated
as market discounts. Market premiums and discounts are amortized over the stated
life of each applicable security.
 
D. FEDERAL INCOME TAXES--It is the Trust'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 Trust 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 such losses against any future realized capital
gains. At July 31, 1998, the Trust had an accumulated capital loss carryforward
for tax purposes of $3,873,769, which will expire between July 31, 2004 and July
31, 2006. Net realized gains or losses may differ for financial and tax
reporting purposes primarily as a result of wash sales, past October losses
which may not be recognized for tax purposes until the first day of the
following fiscal year and losses that were recognized for tax purposes but not
for book purposes at the end of the fiscal year.

    At January 31, 1999, for federal income tax purposes cost of long- and
short-term investments is $7,804,800,175, the aggregate gross unrealized
appreciation is $21,381,523 and the aggregate gross unrealized depreciation is
$50,083,221 resulting in net unrealized depreciation of $28,701,698.
 
E. DISTRIBUTION OF INCOME AND GAINS--The Trust 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.

Under the terms of the Trust's Investment Advisory Agreement, the Adviser will
provide investment advice and facilities to the Trust for an annual fee payable

</TABLE>
 
    In addition, the Trust will pay a monthly administrative fee to Van Kampen
Funds Inc., the Trust's Administrator, at an annual rate of .25% of the average
net assets of the Trust. 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
Trust's portfolio and providing certain services to the holders of the Trust's
securities.

    For the six months ended January 31, 1999, the Trust recognized expenses of
approximately $181,900 representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom (Illinois), counsel to the Trust, of which a trustee of
the Trust is an affiliated person.

    For the six months ended January 31, 1999, the Trust recognized expenses of
approximately $43,400 representing Van Kampen Funds Inc. or its affiliates'
(collectively "Van Kampen") cost of providing legal services to the Trust.

    Van Kampen Investor Services Inc., ("VKIS"), an affiliate of the Adviser,
serves as the shareholder servicing agent of the Trust. For the six months ended
January 31, 1999, the Trust recognized expenses for these services of
approximately $2,722,400. 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 Trust are also officers and directors
of Van Kampen. The Trust does not compensate its officers or trustees who are
officers of Van Kampen.

    The Trust 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

7. COMMITMENTS

Pursuant to the terms of certain of the Variable Rate Senior Loan agreements,
the Trust had unfunded loan commitments of approximately $355,102,634 as of
January 31, 1999. The Trust generally will maintain with its custodian
short-term investments having an aggregate value at least equal to the amount of
unfunded loan commitments.

    The 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
April 15, 1999. The proceeds of any borrowing by the Trust 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 Trust for
its shares. Annual commitment fees of .065% 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 .375%. There have been no borrowings
under this agreement to date. The Trust is currently evaluating alternative
credit arrangements to provide additional liquidity for tender offers. The Trust
expects that any such arrangements would have customary covenants and default
limitations. There can be no assurance that the Trust will enter into future
credit arrangements.

8. SENIOR LOAN PARTICIPATION COMMITMENTS

The Trust invests primarily in participations, assignments, or acts as a party
to the primary lending syndicate of a Variable Rate Senior Loan interest to
United States corporations, partnerships, and other entities. When the Trust
purchases a participation of a Senior Loan interest, the Trust 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 Trust assumes
the credit risk of the borrower, Selling Participant or other persons
interpositioned between the Trust and the borrower.

    At January 31, 1999, the following sets forth the selling participants with
respect to interests in Senior Loans purchased by the Trust on a participation
basis.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
The Board of Trustees and Shareholders of
 
Van Kampen Prime Rate Income Trust:
 
We have audited the accompanying statement of assets and liabilities of Van
Kampen Prime Rate Income Trust (the "Trust"), including the portfolio of
investments, as of July 31, 1998, and the related statements of operations and
cash flows for the year then ended, the statement of changes in net assets for
each of the two years in the period then ended, and the financial highlights for
each of the periods presented. These financial statements and financial
highlights are the responsibility of the Trust'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 generally accepted auditing
standards. 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 July
31, 1998, by correspondence with the custodian and selling or agent banks; where
replies were not received 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 Van Kampen Prime Rate Income Trust as of July 31, 1998, the results
of its operations and cash flows 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 periods presented, in conformity with generally
accepted accounting principles.

NR = Not rated
 
(a) This Senior Loan interest is non-income producing.
 
(b) This Borrower has filed for protection in federal bankruptcy court.
 
(c) Restricted security.
 
(d) Non-income producing security as this stock currently does not declare
    dividends.
 
+  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.
 
*  Senior Loans in the Trust'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 Trust's portfolio may occur. As a
   result, the actual remaining maturity of Senior Loans held in the Trust's
   portfolio may be substantially less than the stated maturities shown.
   Although the Trust is unable to accurately estimate the actual remaining
   maturity of individual Senior Loans, the Trust 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 Trust 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 prime rate offered by
   one or more major United States banks, (ii) the lending rate offered by one
   or more major European banks, such as the London Inter-Bank Offered Rate
   ('LIBOR') and (iii) the certificate of deposit rate. Senior loans are
   generally considered to be restricted in that the Trust 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 Prime Rate Income Trust, formerly known as Van Kampen American
Capital Prime Rate Income Trust, (the "Trust") is registered as a
non-diversified closed-end management investment company under the Investment
Company Act of 1940, as amended. The Trust's investment objective is to provide
a high level of current income, consistent with preservation of capital. The
Trust seeks to achieve its objective by investing primarily in a portfolio of
interests in floating or variable rate senior loans to United States
corporations, partnerships and other entities. The Trust commenced investment
operations on October 4, 1989.
 
       The following is a summary of significant accounting policies
consistently followed by the Trust 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 value of the Trust's Variable Rate Senior Loan
interests, totaling $6,617,436,013 (90.5% of net assets) is determined in the
absence of actual market values by Van Kampen Investment Advisory Corp. (the
"Adviser") following guidelines and procedures established, and periodically
reviewed, by the Board of Trustees. The value of a Variable Rate Senior Loan
interest in the Trust's portfolio is determined with reference to changes in
market interest rates and to the creditworthiness of the underlying obligor. In
valuing Variable Rate Senior Loan interests, the Adviser considers market
quotations and transactions in instruments that the Adviser believes may be
comparable to such Variable Rate Senior Loan interests. In determining the
relationship between such instruments and the Variable Rate Senior Loan
interests, the Adviser considers such factors as the creditworthiness of the
underlying obligor, the current interest rate, the interest rate redetermination
period and maturity date. To the extent that reliable market transactions in
Variable Rate Senior Loan interests have occurred, the Adviser also considers
pricing information derived from such secondary market transactions in valuing
Variable Rate Senior Loan interests. Because of uncertainty inherent in the
valuation process, the estimated value of a Variable Rate Senior Loan interest
may differ significantly from the value that would have been used had there been
market activity for that Variable Rate Senior Loan interest. Equity securities
are valued on the basis of prices furnished by pricing services or as determined
in good faith by the Adviser. Short-term securities with remaining maturities of
60 days or less are valued at amortized cost.
 
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 recognized as income ratably over the expected life of the
loan. Facilities fees on senior loans purchased after July 31, 1997, are treated
as market discounts. Market premiums and discounts are amortized over the stated
life of each applicable security.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
                                 July 31, 1998
- --------------------------------------------------------------------------------
 
D. FEDERAL INCOME TAXES--It is the Trust'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 Trust 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 such losses against any future
realized capital gains. At July 31, 1998, the Trust had an accumulated capital
loss carryforward for tax purposes of $3,873,769, which will expire between July
31, 2004 and July 31, 2006. Net realized gains or losses may differ for
financial and tax reporting purposes primarily as a result of wash sales, past
October losses which may not be recognized for tax purposes until the first day
of the following fiscal year and losses that were recognized for tax purposes
but not for book purposes at the end of the fiscal year.
 
       At July 31, 1998, for federal income tax purposes cost of long- and
short-term investments is $7,264,846,206, the aggregate gross unrealized
appreciation is $37,643,032 and the aggregate gross unrealized depreciation is
$48,564,348 resulting in net unrealized depreciation of $10,921,316.
 
E. DISTRIBUTION OF INCOME AND GAINS--The Trust 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.
 
       Due to inherent differences in the recognition of income, expenses and
realized gains/losses under generally accepted accounting principles and federal
income tax purposes, permanent differences between financial and tax basis
reporting for the 1998 fiscal year have been identified and appropriately
reclassified. Permanent differences relating to expenses which are not
deductible for tax purposes totaling $293,828 were reclassified from accumulated
undistributed net investment income to capital, $3,294,396 relating to losses
recognized on the sale of securities which are deferred for tax purposes were
reclassified from accumulated net realized gains/losses to capital and
$5,243,036 relating to income and gain/loss recognized on restructured
securities were reclassified from accumulated net investment income to
accumulated net realized gain/loss.
 
2. INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES
 
Under the terms of the Trust's Investment Advisory Agreement, the Adviser will
provide investment advice and facilities to the Trust for an annual fee payable
monthly as follows:

</TABLE>
 
       In addition, the Trust will pay a monthly administrative fee to Van
Kampen Funds Inc., the Trust's Administrator, at an annual rate of .25% of the
average net assets of the Trust. 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
Trust's portfolio and providing certain services to the holders of the Trust's
securities.

- --------------------------------------------------------------------------------
 
       For the year ended July 31, 1998, the Trust recognized expenses of
approximately $375,100 representing legal services provided by Skadden, Arps,
Slate, Meagher & Flom (Illinois), counsel to the Trust, of which a trustee of
the Trust is an affiliated person.
 
       For the year ended July 31, 1998, the Trust recognized expenses of
approximately $81,300 representing Van Kampen Funds Inc. or its affiliates'
(collectively "Van Kampen") cost of providing legal services to the Trust.
 
       Van Kampen Investor Services Inc., ("VKIS"), an affiliate of the Adviser,
serves as the shareholder servicing agent of the Trust. For the year ended July
31, 1998, the Trust recognized expenses for these services of approximately
$5,423,300. Beginning in 1998, the 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 Trust are also officers and
directors of Van Kampen. The Trust does not compensate its officers or trustees
who are officers of Van Kampen.
 
       The Trust 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 Trust. The maximum
annual benefit per trustee under the plan is $2,500.

7. COMMITMENTS
 
Pursuant to the terms of certain of the Variable Rate Senior Loan agreements,
the Trust had unfunded loan commitments of approximately $417,155,600 as of July
31, 1998. The Trust generally will maintain with its custodian short-term
investments having an aggregate value at least equal to the amount of unfunded
loan commitments.
    The Trust has entered into a revolving credit agreement with a syndicate led
by Bank of America for an aggregate of $500,000,000. The proceeds of any
borrowing by the Trust 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 Trust for its shares. Annual commitment
fees of .065% 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 .375%. There have been no borrowings under this agreement to
date.

8. SENIOR LOAN PARTICIPATION COMMITMENTS
 
The Trust invests primarily in participations, assignments, or acts as a party
to the primary lending syndicate of a Variable Rate Senior Loan interest to
United States corporations, partnerships, and other entities. When the Trust
purchases a participation of a Senior Loan interest, the Trust 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 Trust assumes
the credit risk of the borrower, Selling Participant or other persons
interpositioned between the Trust and the borrower.
    At July 31, 1998, the following sets forth the selling participants with
respect to interests in Senior Loans purchased by the Trust on a participation
basis.

9. YEAR 2000 COMPLIANCE (UNAUDITED)
 
Van Kampen utilizes a number of computer programs across its entire operation
relying on both internal software systems as well as external software systems
provided by third parties. In 1996 Van Kampen initiated a CountDown 2000 Project
to review both the internal systems and external vendor connections. The goal of
this project is to position our business to continue unaffected as a result of
the century change. At this time, there can be no assurance that the steps taken
will be sufficient to avoid any adverse impact to the Trust, but we do not
anticipate that the move to Year 2000 will have a material impact on our ability
to continue to provide the Trust with service at current levels. In addition, it
is possible that the securities markets in which the Trust invests may be
detrimentally affected by computer failures throughout the financial services
industry beginning January 1, 2000. Improperly functioning trading systems may
result in settlement problems and liquidity issues.

ITEM 29: INDEMNIFICATION
 
     Please see Article 5.3 of the Registrant's Amended and Restated Declaration
of Trust (Exhibit (a)(i)) for indemnification of officers and trustees.
Registrant's trustees and officers are also covered by an Errors and Omissions
Policy. Section 5 of the proposed Investment Advisory Agreement between the Fund
and the Adviser provides that in the absence of willful misfeasance, bad faith
or gross negligence in connection with the obligations or duties under the
Investment Advisory Agreement or on the part of the Adviser, the Adviser shall
not be liable to the Fund or to any Common Shareholder of the Fund for any act
or omission in the course of or connected in any way with rendering services or
for any losses that may be sustained in the purchase, holding or sale of any
security. The Distribution Agreement provides that the Registrant shall
indemnify the Distributor (as defined therein) and certain persons related
thereto for any loss or liability arising from any alleged misstatement of a
material fact (or alleged omission to state a material fact) contained in, among
other things, the Registration Statement or Prospectus except to the extent the
misstated fact or omission was made in reliance upon information provided by or
on behalf of the Distributor. (See Section 7 of the Distribution Agreement.)
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to trustees, officers and controlling persons of the
Registrant and the Adviser and any underwriter pursuant to the foregoing
provisions or otherwise, the Registrant has been advised that in the opinion of
the Securities and Exchange Commission such indemnification is against public
policy as expressed in such Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the Registrant of expenses incurred or paid by a trustee, officer, or
controlling person or the Registrant and the principal underwriter in connection
with the successful defense of any action, suit or proceeding) is asserted
against the Registrant by such trustee, officer or controlling person or the
Distributor in connection with the Common Shares being registered, the
Registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question whether such indemnification by it is against public policy as
expressed in such Act and will be governed by the final adjudication of such
issue.

ITEM 33: UNDERTAKINGS
 
     1. Registrant undertakes to suspend offering of its Shares until it amends

prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) to
reflect in the Prospectus any facts or events arising after the effective date
of the registration statement (or the most recent post-effective amendment
thereof) which, individually or in the aggregate, represent a fundamental change
in the information set forth in the registration statement; and (iii) to include
any material information with respect to the plan of distribution not previously
disclosed in the registration statement or any material change to such
information in the registration statement.
 
     (b) That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new

fide offering thereof.
 
     (c) To remove from registration by means of post-effective amendment any of
the securities being registered which remain unsold at the termination of the
offering.
 
     5. If applicable:
 
          (a) For purpose of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of a registration statement in reliance upon Rule 430A and contained in the
     form of prospectus filed by the Registrant pursuant to Rule 497(h) under
     the Securities Act of 1933, shall be deemed to be part of this Registration
     Statement as of the time it was declared effective.
 
          (b) For the purpose of determining any liability under the Securities
     Act of 1933, each post-effective amendment that contains a form of
     prospectus shall be deemed to be a new registration statement relating to
     the securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.
 
     6. The Registrant undertakes to send by first class mail or other means
designed to ensure equally prompt delivery, within two business days of receipt
of a written or oral request, its Statement of Additional Information.

                                DEALER AGREEMENT
                           WITH VAN KAMPEN FUNDS INC.
                              REGARDING VAN KAMPEN
                  OPEN-END AND CLOSED-END INVESTMENT COMPANIES


Ladies and Gentlemen:

     As dealer for our own account, we offer to sell to you shares of any of
the Van Kampen open-end investment companies (the "Open-End Funds" or,
individually, an "Open-End Fund") and Van Kampen closed-end investment
companies (the "Closed-End Funds" or, individually, a "Closed-End Fund")
distributed by Van Kampen Funds Inc. ("VK Funds") pursuant to the terms and
conditions contained herein. Collectively, the Open-End Funds and Closed-End
Funds sometimes are referred to herein as the "Funds" or, individually,
as a "Fund".

     VK Funds acts as the principal underwriter (as such term is defined in the
Investment Company Act of 1940, as amended) for each Fund with respect to its
offering of one or more classes of shares as described in each Fund's
Prospectus.  Pursuant to this Agreement, VK Funds offers to sell to you shares
of each Open-End Fund and each Closed-End Fund prior to the Effective Date (as
defined herein) of each Fund's Registration Statement (as defined herein) (the
"Initial Offering Period") and after the Effective Date of each Fund's
Registration Statement (the "Continuous Offering Period") (if any) as described
in each respective Fund's Prospectus.

     As used herein unless otherwise indicated, the term "Prospectus" means the
final prospectus and Statement of Additional Information included in the
registration statement for the fund on the effective date and as from time to
time thereafter amended or supplemented.  As used herein unless otherwise
indicated, the term "Preliminary Prospectus" means any preliminary prospectus
and any preliminary Statement of Additional Information included at any time as
a part of the registration statement for any Fund prior to the effective date
and which is authorized by VK Funds for use in connection with the offering
of shares.

     In consideration of the mutual obligations contained herein, the
sufficiency of which is hereby acknowledged by you, the terms of the Agreement
are as follows:

GENERAL TERMS AND CONDITIONS

     1.  Your acceptance of this Agreement constitutes a representation that
you are a broker-dealer registered with the Securities and Exchange Commission
(the "SEC") and a member in good standing of the National Association of
Securities Dealers, Inc. (the "NASD") or, in the alternative, that you are a
foreign dealer or bank, not required to be registered as a broker-dealer with
the SEC and not required or eligible for membership in the NASD.  If you are
such an NASD member, you agree that in making sales of shares of the one or
more classes of shares of each Fund you will comply with all applicable rules
of the NASD, including without limitation rules pertaining to the opening,
approval, supervision and monitoring of customer accounts, the NASD's
Interpretation with Respect to Free-Riding and Withholding and Sections 8, 24
and 36 of Article III of the NASD's Rules of Fair Practice.  If you are such an
unregistered foreign dealer or bank, you agree not to offer or sell, or to
agree to offer or sell, directly or indirectly, except through VK Funds,
any shares to any party to whom such shares may not be sold unless you are
so registered and a member of the NASD, and in making sales of such shares
you agree to comply with the NASD's Interpretation with Respect to Free-Riding
and Withholding and Sections 8, 24 and 36 of Article III of the NASD's Rules
of Fair Practice as though you were a member in


                                      1

<PAGE>   2





good standing of the NASD and to comply with Section 25 of such Article III as
it applies to a nonmember broker or dealer in a foreign country.  You and we
agree to abide by all other Rules and Regulations of the NASD, including
Section 26 of its Rules of Fair Practice, and all applicable state and Federal
laws, rules and regulations.  Your acceptance also constitutes a representation
that you have been duly authorized by proper corporate or partnership action to
enter into this Agreement and to perform your obligations hereunder.  You will
not accept any orders from any broker, dealer or financial institution who is
purchasing from you with a view toward distribution unless you have obtained
such person's or entity's written consent to be bound by the terms of this
Agreement.

     2.  In all sales of shares of the Funds to the public you shall act as
dealer for your own account, and you shall have no authority in any transaction
to act as agent for the Fund or for VK Funds.

     3.  Each Fund has filed with the SEC and the securities commissions of one
or more states a Registration Statement (the "Registration Statement") on the
SEC Form applicable to the respective Fund.  The date on which the Registration
Statement is declared effective by the SEC is referred to herein as the
"Effective Date".  Prior to the Effective Date of the Registration Statement
with respect to a particular Fund, you expressly acknowledge and understand
that with respect to such Fund:

     (a)  Shares of such Fund may not be sold, nor may offers to buy be
accepted, (i) in any state prior to the Effective Date of the Registration
Statement with respect thereto or (ii) in any state in which such offer or sale
would be unlawful prior to registration or qualification under the securities
laws of such state.

     (b)  The Fund's Preliminary Prospectus, together with any sales material
distributed for use in connection with the offering of shares of such Fund,
does not constitute an offer to sell or the solicitation of an offer to buy
shares of such Fund and is subject to completion and modification by the
Prospectus.  You agree that you will distribute to the public only (a) the
Preliminary Prospectus, the Prospectus and any amendment or supplement thereto
and (b) sales literature or other documents expressly authorized for such
distribution by VK Funds.

     (c)  In the event that you transmit indications of interest to VK Funds
for accumulation prior to the Effective Date, you will be responsible for
confirming such indications of interest with your customers following the
Effective Date.  Indications of interest with respect to shares of a class of a
Fund's shares transmitted to VK Funds prior to the Effective Date will be
conditioned upon the occurrence of the Effective Date and the registration or
qualification of the respective class of shares in the respective state.

     (d)  Indications of interest with respect to shares of a class of a Fund's
shares which are not canceled by you prior to the latter of the Effective Date
and the registration or qualification of the respective class of the Fund's
shares in the respective state, and accepted by VK Funds will be deemed by
VK Funds to be orders for shares of such class of shares of the Fund.

     (e)  All indications of interest and orders transmitted to VK Funds are
subject to the terms and conditions of the Prospectus and this Agreement.

     4.  After the Effective Date, you will not offer shares of a class of the
Fund's shares for sale in any state where they are not qualified for sale under
the "blue sky" laws and regulations of such state or where you are not
qualified to act as a dealer, except for states in which they are exempt from
qualification.

     5.  In the event that you offer shares of the Fund for sale outside the
United States, you agree to comply with the applicable laws, rules and
regulations of the foreign government having jurisdiction over such sales,
including any regulations of the United States military authorities applicable
to solicitations to military personnel.

                                      2

<PAGE>   3
     6.  Upon application to VK Funds, VK Funds will inform you as to the
jurisdictions in which VK Funds believes shares of a Fund have been qualified 
for sale under the respective securities or "blue sky" laws of such 
jurisdictions. VK Funds understands and agrees that qualification of any shares 
of a Fund for sale in such jurisdictions shall be solely VK Funds' 
responsibility and that you assume no responsibility or obligation with respect 
to such eligibility.  You understand and agree that your compliance with the 
requirements of the securities or "blue sky" laws in each jurisdiction with 
respect to your right to sell the shares in such jurisdiction shall be solely 
your responsibility.

     7.  No person is authorized to make any representations concerning any
class of shares of a Fund except those contained in the Fund's current
Preliminary Prospectus or Prospectus, as the case may be.  In purchasing shares
from us you shall rely solely on the representations contained in such
Prospectus. VK Funds will furnish additional copies of a Fund's current
Prospectus and sales literature issued by VK Funds in reasonable quantities upon
request.

     8.  Orders received from you will be accepted by VK Funds only at the
public offering price applicable to each order as specified in the then-current
Fund Prospectus.  The minimum dollar purchase of any shares of each Fund by any
person shall be the applicable minimum dollar amount described in the
then-current Fund Prospectus for that class of shares, and no order for less
than such amount will be accepted hereunder.  The procedures relating to the
handling of orders shall be subject to instructions that VK Funds shall
communicate from time to time to you.  All orders are subject to acceptance or
rejection by VKAC in its sole discretion.

     9.  Payment for Fund shares shall be made on or before the settlement date
specified in the VK Funds confirmation at the office of VK Funds' clearing
agent, or wire to the order of the Fund which reserves VK Funds' right to delay
issuance or transfer of shares until such check has cleared.  If such payment is
not received by VK Funds, VK Funds reserves the right, without notice, forthwith
either to cancel the sale or, at its option, to sell the shares ordered back to
the Fund, and in either case, VK Funds may hold you responsible for any loss
suffered by the Fund.  You agree that in transmitting investors' funds, you will
comply with Rule 15c2-4 under the Securities Exchange Act of 1934, as amended.

     10.  You shall not withhold placing orders with VK Funds from your
customers so as to profit yourself as a result of such withholding; e.g., by a
change in the net asset value from that used in determining the public offering
price to your customers.

     11.  VK Funds will not accept from you any conditioned orders for shares,
except at a definite, specified price.

     12.  You represent that you are familiar with Release No. 4968 under the
Securities Act of 1933, as amended, and Rule 15c2-8 under the Securities
Exchange Act of 1934, as amended, as it relates to the distribution of
Preliminary Prospectuses (and not Statements of Additional Information) and
Prospectuses (and not Statements of Additional Information) for each Fund and
agree that you will comply therewith.  You agree that if an investor or
potential investor places a request with you to receive a Statement of
Additional Information, you will (i) provide such person with a Statement of
Additional Information without charge and notify the Fund that you have done so,
(ii) notify the Fund of the request so that the Fund can fulfill the request or
(iii) tell such person to request a Statement of Additional Information by
telephoning the Fund at the number set forth on the cover of the current
Prospectus or Preliminary Prospectus.  You also agree to keep an accurate record
of your distribution (including dates, number of copies and persons to whom
sent) of copies of any Preliminary Prospectus (and any Statement of Additional
Information) and/or Prospectus (and any Statement of Additional Information) for
each Fund (or any amendment or supplement to either) and, promptly upon request
by VK Funds, to bring all subsequent changes to such Preliminary Prospectus or
Prospectus to the attention of anyone to whom such material shall have been
distributed.  You further agree to furnish to persons who receive a confirmation
of sale of shares of any Fund a copy of the Prospectus (and not the Statement of
Additional Information) for such Fund filed pursuant to Rule 497 under the
Securities Act of 1933, as amended.

     14.  VK Funds will have no liability to you, except for lack of good faith
and for obligations expressly assumed by VK Funds in this Agreement.

     15.  All communications to VK Funds shall be sent to 1 Parkview Plaza, 
PO Box 5555 Oakbrook Terrace, Illinois 60181-5555, Attention:  Mutual Fund

writing.

shall be considered to create a joint venture or partnership between VK Funds
and you.

     17.  This Agreement shall be construed in accordance with the laws of the
State of Illinois without reference to the choice-of-law principles thereof.

     18.  The Fund reserves the right in its discretion and VK Funds reserves
the right in its discretion, without notice, to suspend or withdraw the offering
of any shares of a Fund entirely.  VK Funds reserves the right, without notice,
to amend, modify or cancel the Agreement.  The Agreement may not be assigned by
either party without prior written consent of the other party.

TERMS AND CONDITIONS APPLICABLE ONLY TO OPEN-END FUNDS

     20.  Each of the Open-End Fund's is subject to an alternative distribution
plan (the "Alternative Distribution Plan") as described in such Fund's
then-current Prospectus pursuant to which the Open-End Fund may sell multiple
classes of its shares with varying combinations of front-end service charges
(each a "FESC"), distributions fees, service fees, contingent deferred sales
charges (each a "CDSC"), exchange features, conversion rights, voting rights,
expenses allocations and investment requirements.  As used herein, classes of
shares of a Fund subject to a FESC will be referred to as FESC Shares, and
classes of shares of a Fund subject to a CDSC will be referred to as CDSC
Shares.
+
     21.(a)  With respect to any shares of a class of FESC Shares of an
Open-End Fund, the public offering price for such shares shall be the net asset
value per share plus a FESC, expressed as a percentage of the applicable public
offering price, as determined and effective as of the time specified in the
then-current Prospectus of such Open-End Fund.  The dealer discount applicable
to any sale of shares of a class of FESC Shares of an Open-End Fund shall be a
percentage of the applicable public offering price for such shares as provided
for in the then-current Prospectus of such Open-End Fund or, if not so
provided, as provided to you from time to time in writing by VK Funds.

     (b)  With respect to any shares of a class of CDSC Shares of an Open-End
Fund, the public offering price for such shares shall be the net asset value per
share as determined and effective as of the time specified in the then-current
Prospectus of such Open-End Fund.  The dealer sales compensation payable by VK
Funds applicable to any sale of shares of a class of CDSC Shares of an Open-End
Fund shall be the percentage of the applicable public offering price for such
shares as provided for in the then-current Prospectus of such Open-End Funds or,
if not so provided, as provided to you from time to time in writing by VK Funds.

     22.  Should you wish to participate in the Distribution Plan with respect
to a class of shares adopted by an Open-End Fund pursuant to Rule 12b-1 ("Rule
12b-1 Plan") under the Investment Company Act of 1940, as amended, or the
Service Plan with respect to a class of shares, it is understood that you must
be approved by the Board of Directors of such Open-End Fund and execute a
Distribution Assistance Agreement.

                                      4

     23.  With respect to the Open-End Funds, your acceptance of this Agreement
constitutes a representation that you will adopt policies and procedures to
comply with Rule 18f-3 under the Investment Company Act of 1940, with respect to
when you may appropriately sell the various classes of shares of the Open-End
Funds to investors and that you will sell such shares only in accordance
therewith.

     24.(a)  You agree to purchase shares of an Open-End Fund only from VK Funds
or from your customers.  If you purchase shares of an Open-End Fund from VK
Funds, you agree that all such purchases shall be made only:  (i) to cover
orders already received by you from your customers or (ii) for your own bona
fide investment. If you purchase shares of an Open-End Fund from your customers,
you agree to pay such customers not less than the applicable repurchase price
for such shares as established by the then-current Prospectus for such Open-End
Fund. VK Funds in turn agrees that it will not purchase any shares from an
Open-End Fund except for the purpose of covering purchase orders that it has
already received.

             (b)  With respect to shares of a class of CDSC Shares of an
Open-End Fund purchased from your customers, you additionally agree to resell
such shares only to VK Funds as agent for the Fund at the repurchase price for
such shares as established by the then-current Prospectus of such Open-End Fund.
You acknowledge and understand that shares of a class of CDSC Shares of an
Open-End Fund may be subject to a CDSC payable to VK Funds as set forth in the
Prospectus for such Open-End Fund in effect at the time of the original purchase
of such shares from the Open-End Fund and that the repurchase price for such
shares that will be paid by VK Funds will reflect the imposition of any
applicable CDSC.

     25.(a)  You shall sell shares of a class of shares of an Open-End Fund
only:  (i) to customers at the applicable public offering price or (ii) to VK
Funds as agent for the Open-End Fund at the repurchase price in the then-current
Prospectus of such Open-End Fund.  In such a sale to VK Funds, you may act
either as principal for your own account or as agent for your customer.  If you
act as principal for your own account in purchasing shares of a class of shares
of an Open-End Fund for resale to VK Funds, you agree to pay your customer not
less than the price that you receive from VK Funds.  If you act as agent for
your customer in selling shares of a class of shares of an Open-End Fund to VK
Funds, you agree not to charge your customer more than a fair commission for
handling the transaction.  You acknowledge and understand that CDSC Shares of an
Open-End Fund may be subject to a CDSC payable to VK Funds as set forth in the
Prospectus of such Open-End Fund in effect at the time of the original purchase
of such CDSC Shares and that the repurchase price that will be paid by VK Funds
for such CDSC Shares will reflect the imposition of any such CDSC.

     26.  If any shares of a class of FESC Shares of an Open-End Fund sold to or
by you under the terms of this Agreement are repurchased by the Fund or by VK
Funds as agent for the Fund or are tendered for redemption within seven business
days after the date of VK Funds' confirmation of the original purchase, it is
agreed that you shall forfeit your right to any dealer discount received by you
on such FESC Shares.  VK Funds will notify you of any such repurchase or
redemption within ten business days from the date on which the repurchase or
redemption order in proper form is delivered to VK Funds or to the Fund, and you
shall forthwith refund to VK Funds the full dealer discount allowed to you on
such sale. VK Funds agrees, in the event of any such repurchase or redemption,
to refund to the Fund its share of any discount allowed to VK Funds and, upon
receipt from you of the refund of the discount allowed to you, to pay such
refund forthwith to the Fund.

TERMS AND CONDITIONS APPLICABLE TO CLOSED END-FUNDS

     27.  No Closed-End Fund will issue fractional shares.

     28.  VK Funds may, in its sole discretion, allocate shares of a Closed-End
Fund among brokers and dealers participating in the Initial Offering Period or
among brokers, dealers and banks in the Continuous Offering Period, as the case
may be, on other than a pro rata basis, which may result in

                                      5

<PAGE>   6

certain brokers, dealers and banks not being allocated the full amount of
shares of such fund sold by them while certain other brokers, dealers and banks
may receive their full allocation.

     29.  You agree that with respect to orders for shares of a Closed-End Fund,
you will transmit such orders received during the Initial Offering Period to VK
Funds within the time period as specified in such Closed-End Fund's Prospectus
(or in the time period as extended by VK Funds in writing).  You also agree to
transmit any customer order received during the Continuous Offering Period to VK
Funds prior to the time that the public offering price for such Closed-End Fund
is next determined after your receipt of such order as set forth in the
Closed-End Fund's Prospectus.  There is no assurance that each Closed-End Fund
will engage in a continuous offering of shares.

     30.  On each order accepted by VK Funds for shares of a Closed-End Fund,
you will be entitled to receive a concession paid out of VK Funds' own assets
as set forth in the then-current Prospectus of such Closed-End Fund (exclusive
of additional compensation that may be payable pursuant to sales programs, if
any, that may be established from time to time as described in the Prospectus
for such Closed-End Fund, which will be payable only as and to the extent the
requirements of such programs are satisfied).  In no event will any Closed-End
Fund reimburse VK Funds for any such sales concessions or other additional
compensation or pay any such concession or other additional compensation or
allowance directly to you. VK Funds will specify for each Closed-End Fund a
period after the date that the shares of such Closed-End Fund are listed on the
New York Stock Exchange, the American Stock Exchange or another national
securities market system (which period will end no later that the first dividend
payment date with respect to such Closed-End Fund) during which sales
concessions and other additional compensation are subject to forfeiture as
provided in the following sentence (the "Forfeiture Period").  During the
Forfeiture Period for any Closed-End Fund, physical delivery of certificates
representing shares will be required to transfer ownership of such shares.  In
the event that any shares of a Closed-End Fund sold through an order received
from you in the Initial Offering Period or the Continuous Offering Period are
resold in the open market or otherwise during the Forfeiture Period, VK Funds
reserves the right to require you to forfeit any sales concessions and other
additional compensation with respect to such shares.  In the event of a
forfeiture, VK Funds may withhold any forfeited sales concessions and other
additional compensation that has not yet been paid or from other amounts yet to
be paid to you (whether or not payable with respect to such shares) and you
agree to repay to VK Funds, promptly upon demand, any forfeited sales
concessions and other compensation that has been paid.  Determinations of the
amounts to be paid to you or by you to VK Funds shall be made by VK Funds and
shall be conclusive.

     31.  During the Initial Offering Period and any Continuous Offering Period
for any Closed-End Fund, you agree to supply VK Funds, not less frequently than
once a week by Friday, 5:00 p.m. Eastern Time, during such Closed-End Fund's
Initial Offering Period, a list setting forth by state and in the aggregate all
indications of interest and, during any Continuous Offering Period, all shares
sold by you of such Closed-End Fund during such week (or lesser period of time),
and a list setting forth by name and location each registered representative
making said sales and indicating the amount of all sales per Closed-End Fund to
date.

     32.  You expressly acknowledge and understand that there is no Rule 12b-1
Plan for the Closed-End Funds.

     33.  You expressly acknowledge and understand that shares of the Closed-End
Funds will not be repurchased by either the Closed-End Funds (other than through
tender offers from time to time, if any) or by VK Funds and that no secondary
market for such shares is expected to develop until the shares have begun
trading on a national exchange or national market system.  You hereby covenant
that, until notified by VK Funds that the distribution of such shares has been
completed or that the Forfeiture Period has ended, you (a) will not make a
secondary market in any shares of such a Closed-End Fund, (b) will not purchase
or hold shares of such Closed-End Fund in inventory for the purpose of resale in
the open market or to your customers and (c) without VK Funds' consent, will
not repurchase shares of such Closed-End Fund in the open market or from your
customers for any account in which you have a beneficial interest.

                                      6

<PAGE>   7




     34.  Unlike the other Closed-End Funds, the Continuous Offering period with
respect to the Van Kampen Prime Rate Income Trust (the "Prime Rate Fund") may
continue indefinitely.  The offer to sell shares of the Prime Rate Fund is
subject to further terms and conditions in addition to those set forth above as
follows:

              (a)  You expressly acknowledge and understand that shares of the
Prime Rate Fund will not be repurchased by either the Prime Rate Fund (other 
than through tender offers from time to time, if any) or VK Funds, and that no 
secondary market for the shares of the Prime Rate Fund exists currently, or is
expected to develop.  You also expressly acknowledge and agree that, in the 
event your customer cancels their order for shares after confirmation, such 
shares may not be repurchased, remarketed or otherwise disposed of by or 
through VK Funds.

              (b)  You acknowledge and understand that, while the Board of
Trustees of the Prime Rate Fund intends to consider tendering for all or a
portion of the Prime Rate Fund's shares on a quarterly basis, there is no
assurance the Prime Rate Fund will tender for shares at any time or, following
such a tender offer, that shares so tendered will be repurchased by the Prime
Rate Fund.  You acknowledge and understand that an early withdrawal charge
payable to VK Funds will be imposed on most shares accepted for tender by the
Prime Rate Fund which have been held for less than five years, as set forth in
the Prime Rate Fund's Prospectus.  ANY REPRESENTATION AS TO A TENDER OFFER BY
THE PRIME RATE FUND, OTHER THAN THAT WHICH IS SET FORTH IN THE PRIME RATE FUND'S
CURRENT PROSPECTUS IS EXPRESSLY PROHIBITED.

     Please accept the foregoing by signing this Dealer Agreement, keeping a
copy for your files and returning the original to us.

                   BROKER FULLY DISCLOSED CLEARING AGREEMENT
                           WITH VAN KAMPEN FUNDS INC.
                              REGARDING VAN KAMPEN
                  OPEN-END AND CLOSED-END INVESTMENT COMPANIES



Ladies and Gentlemen:

     As dealer for our own account, we offer to make available to you shares of
any of the Van Kampen open-end investment companies (the "Open-End Funds" or,
individually, an "Open-End Fund") and Van Kampen closed-end investment companies
(the "Closed-End Funds" or, individually, a "Closed-End Fund") distributed by
Van Kampen Funds Inc. ("VK Funds") pursuant to the terms and conditions
contained herein.  Collectively, the Open-End Funds and Closed-End Funds
sometimes are referred to herein as the "Funds" or, individually, as a "Fund".
You are a broker-dealer that desires to make available shares of such Funds to
your customers on a fully disclosed basis wherein VK Funds would confirm
transactions of your customers in a Fund directly to them.

     VK Funds acts as the principal underwriter (as such term is defined in the
Investment Company Act of 1940, as amended) for each Fund with respect to its
offering of one or more classes of shares as described in each Fund's
Prospectus.  Pursuant to this Agreement, VK Funds offers to make available to
you shares of each Open-End Fund and each Closed-End Fund, prior to the
Effective Date (as defined herein) of each Fund's Registration Statement (the
"Initial Offering Period") and after the Effective Date of each Fund's
Registration Statement (as defined herein) (the "Continuous Offering Period")
(if any) as described in each respective Fund's Prospectus.

     As used herein unless otherwise indicated, the term "Prospectus" means the
final prospectus and Statement of Additional Information included in the
registration statement for the fund on the effective date and as from time to
time thereafter amended or supplemented.  As used herein unless otherwise
indicated, the term "Preliminary Prospectus" means any preliminary prospectus
and any preliminary Statement of Additional Information included at any time as
a part of the registration statement for any Fund prior to the effective date
and that is authorized by VK Funds for use in connection with the offering of
shares.

     In consideration of the mutual obligations contained herein, the
sufficiency of which is hereby acknowledged by you, the terms of the Agreement
are as follows:

GENERAL TERMS AND CONDITIONS

     1.  Your acceptance of this Agreement constitutes a representation that
you are a securities broker-dealer registered with the Securities and Exchange
Commission (the "SEC") and a member in good standing of the National
Association of Securities Dealers, Inc. (the "NASD").  You agree to abide by
the laws, rules and regulations of the SEC and NASD, including without
limitation rules pertaining to the opening, approval, supervision and
monitoring of customer accounts, the NASD's Interpretation with Respect to
Free-Riding and Withholding and Sections 8, 24 and 36 of Article III of the
NASD's Rules of Fair Practice.  You and we agree to abide by all other Rules
and Regulations of the NASD, including Section 26 of its Rules of Fair
Practice.  Your acceptance also constitutes a representation that you have been
duly authorized by proper corporate or partnership action to enter into this
Agreement and to perform your obligations hereunder.  You will not accept any
orders from any broker, dealer or financial institution who is purchasing from
you with a view toward distribution unless you have obtained such person's or
entity's written consent to be bound by the terms of this Agreement.



                                      1
<PAGE>   2
     2.  For the purposes of the Securities and Exchange Commission's Financial
Responsibility Rules and the Securities Investor's Protection Act, your
customers will be considered customers of VK Funds and not of your firm.  VK
Funds has been granted an exemption from the NASD rules of Fair Practice,
Article III Section 45 requirements to send customer statements and thus will
not do so. Customer statements showing account activity and balances will be
mailed to the customer by the Funds each time a financial transaction occurs in
their account and on a monthly or quarterly basis.  Nothing herein shall cause
your firm's customers to be interpreted as customers of VK Funds for any other
purpose, or to negate the intent of any other section of this agreement,
including, but not limited to, the delineation of responsibilities as set forth
elsewhere in this agreement.

     3.  In transactions where you make available shares of the Funds to the
public, you shall have no authority to act as agent for the Fund or for VK
Funds.

     4.  Each Fund has filed with the SEC and the securities commissions of one
or more states a Registration Statement (the "Registration Statement") on the
SEC form applicable to the respective Fund.  The date on which the Registration
Statement is declared effective by the SEC is referred to herein as the
"Effective Date".  Prior to the Effective Date of the Registration Statement
with respect to a particular Fund, you expressly acknowledge and understand
that with respect to such Fund:

     (a)  Shares of such Fund may not be sold, nor may offers to buy be
accepted, (i) prior to the Effective Date of the Registration Statement or (ii)
in any state in which such offer or sale would be unlawful prior to
registration or qualification under the securities laws of such state.

     (b)  The Fund's Preliminary Prospectus, together with any sales material
distributed for use in connection with the offering of shares of such Fund,
does not constitute an offer to sell or the solicitation of an offer to buy
shares of such Fund and is subject to completion and modification by the
Prospectus.

     (c)  In the event that you transmit indications of interest to VK Funds for
accumulation prior to the Effective Date, upon your instruction VK Funds will
send confirmation of such indications of interest directly to your customers in
writing, together with copies of the Preliminary Prospectus for the Fund, and
send copies of the confirmations to you.  Indications of interest with respect
to shares of a class of a Fund's shares transmitted to VK Funds prior to the
Effective Date are subject to acceptance or rejection by VK Funds in its sole
discretion and are conditioned upon the occurrence of (i) the Effective Date and
(ii) the registration or qualification of the respective class of shares in the
respective state.

     (d)  Indications of interest with respect to shares of a class of a Fund's
shares not cancelled by you prior to or on the later of (i) the Effective Date
and (ii) the registration or qualification of the respective class of shares in
the respective state, and accepted by VK Funds will be deemed by VK Funds to be
orders for Shares.

     (e)  Upon your instruction, VK Funds will send confirmations of orders
accepted by VK Funds (including indications of interest deemed orders) directly
to your customers in writing, together with copies of the Prospectus for the
Fund, and send copies of the confirmations to you.

     (f)  Upon receipt of duplicate confirmations you will examine the same and
promptly notify VK Funds of any errors or discrepancies that you discover and
will promptly bring to VK Funds' attention any errors in such confirmations
claimed by your customers.  All confirmations to your customers will indicate
that orders were placed on a fully disclosed basis.

     (g)  All indications of interest and orders transmitted to VK Funds are
subject to the terms and conditions of the Fund's Prospectus and this Agreement
and are subject to acceptance or rejection by VK Funds in its sole discretion.

     5.  After the Effective Date, you will not make shares of a class of the
Fund's shares available in any state where they are not qualified for sale
under the "blue sky" laws and regulations of such state, except for states in
which they are exempt from qualification.



                                      2

<PAGE>   3
     6.  In the event that you make shares of the Funds available outside the
United States, you agree to comply with the applicable laws, rules and
regulations of the foreign government having jurisdiction over such sales,
including any regulations of the United States military authorities applicable
to solicitations to military personnel.

     7.  Upon application to VK Funds, VK Funds will inform you as to the
jurisdictions in which VK Funds believes shares of a Fund have been qualified
for sale under the respective securities or "blue sky" laws of such
jurisdictions. VK Funds understands and agrees that qualification of any shares
of a Fund for sale in such jurisdictions shall be solely VK Funds'
responsibility and that you assume no responsibility or obligation with respect
to such eligibility.  You understand and agree that your compliance with the
requirements of the securities or "blue sky" laws in each jurisdiction with
respect to your right to make the shares available in such jurisdiction shall be
solely your responsibility.

     8.  No person is authorized to make any representations concerning any
class of shares of a Fund except those contained in the Funds' current
Preliminary Prospectus or Prospectus, as the case may be. In purchasing shares
from us you shall rely solely on the representations contained in such
Prospectus. VK Funds will furnish additional copies of a Funds' current
Prospectus and sales literature issued by VK Funds in reasonable quantities upon
request.

     9.  You agree that you will distribute to the public only (a) the
Preliminary Prospectus, the Prospectus and any amendment or supplement thereto
and (b) sales literature or other documents expressly authorized for such
distribution by VK Funds.

     10.  Orders received from you will be accepted by VK Funds only at the
public offering price applicable to each order as specified in the then-current
Fund Prospectus.  The minimum dollar purchase of any shares of each Fund by any
person shall be the applicable minimum dollar amount described in the
then-current Fund Prospectus for that class of shares, and no order for less
than such amount will be accepted hereunder.  The procedures relating to the
handling of orders shall be subject to instructions that VK Funds shall
communicate from time to time to you.  All orders are subject to acceptance or
rejection by VK Funds in its sole discretion.  Upon acceptance of an order, we
shall confirm directly to the customer in writing upon your instruction and send
a copy of the confirmation to you.  In addition, we will send a Fund Prospectus
with the confirmation.  You agree that upon receipt of duplicate confirmations
you will examine the same and promptly notify VK Funds of any errors or
discrepancies that you discover and shall promptly bring to VK Funds' attention
any errors in such confirmations claimed by your customers.  All confirmations
to your customers will indicate that orders were placed on a fully disclosed
basis.

     11.  Payment for Fund shares shall be made on or before the settlement date
specified in the VK Funds confirmation at the office of VK Funds' clearing
agent, or wire to the order of the Fund which reserves VK Funds' right to delay
issuance of transfer of shares until such check has cleared.  If such payment is
not received by VK Funds, VK Funds reserves the right, without notice, forthwith
either to cancel the trade at our option or as required by the provisions of
Regulation T, and in either case, VK Funds may hold you responsible for any loss
suffered by the Fund.  You agree that in transmitting investors' funds, you will
comply with Rule 15c2-4 under the Securities Exchange Act of 1934, as amended.

     12.  You shall not withhold placing orders with VK Funds from your
customers so as to profit yourself as a result of such withholding; e.g., by a
change in the net asset value from that used in determining the public offering
price to your customers.

     13.  VK Funds will not accept from you any conditioned orders for shares,
except at a definite, specified price.

     14.  You represent that you are familiar with Release No. 4968 under the
Securities Act of 1933, as amended, and Rule 15c2-8 under the Securities
Exchange Act of 1934, as amended, as it relates to the distribution of
Preliminary Prospectuses (and not Statements of Additional Information) and
Prospectuses (and not Statements of Additional Information) for each Fund and
agree that you will comply therewith.  You agree that if an investor or
potential investor places a request with you to receive a Statement of
Additional Information, you will (i) provide such person with a Statement of
Additional Information without charge and notify the Fund that you have done so,
(ii) notify the Fund of the request so that the Fund can fulfill the request or
(iii) tell such person to request a Statement of Additional Information by
telephoning the Fund at the number set forth on the cover of the current
Prospectus or Preliminary Prospectus.  You also agree to keep an accurate record
of your distribution (including dates,

<PAGE>   4

number of copies and persons to whom sent) of copies of any Preliminary
Prospectus (and any Statement of Additional Information) and/or Prospectus (and
any Statement of Additional Information) for each Fund (or any amendment or
supplement to either) and, promptly upon request by VK Funds, to bring all
subsequent changes to such Preliminary Prospectus or Prospectus to the
attention of anyone to whom such material shall have been distributed.  You
further agree to furnish to persons who receive a confirmation of sale of
shares of any Fund a copy of the Prospectus for such Fund filed pursuant to
Rule 497 under the Securities Act of 1933, as amended.  Upon your request,
VK Funds will furnish to such persons a copy of the Prospectus for such Fund
filed pursuant to Rule 497 Under the Securities Act of 1993, as amended.

     15.  The names of your customers shall remain your sole property and shall
not be used by VK Funds for any purpose except for servicing and informational
mailings in the normal course of business to Fund shareholders.

     16.  Unless otherwise indicated in a Fund's Prospectus, stock certificates
for shares sold will be issued to your customers only if specifically
requested.

     17.  VK Funds will have no liability to you, except for lack of good faith
and for obligations expressly assumed by VK Funds in this Agreement.

     18.  All communications to VK Funds shall be sent to 1 Parkview Plaza, P.O.
Box 5555, Oakbrook Terrace, Illinois 60181-5555, Attention:  Mutual Fund
Department. Any notice to you shall be duly given if sent to you at the address
specified by you below or such other address as you may designate to VK Funds in
writing.

     19.  Neither this Agreement nor the performance of the services hereunder
shall be considered to create a joint venture or partnership between VK Funds
and you.

     20.  This Agreement shall be construed in accordance with the laws of the
State of Illinois without reference to the choice-of-law principles thereof.

     21.  The Fund reserves the right in its discretion and VK Funds reserves
the right in its discretion, without notice, to suspend or withdraw the offering
of any shares of a Fund entirely. VK Funds reserves the right, without notice,
to amend, modify or cancel the Agreement.  The Agreement may not be assigned by
either party without prior written consent of the other party.
   
     22.  This Agreement may be terminated at any time by either party.

TERMS AND CONDITIONS APPLICABLE TO OPEN-END FUNDS

     23.  Each of the Open-End Funds is subject to an alternative distribution
plan (the "Alternative Distribution Plan") as described in such Fund's
then-current Prospectus pursuant to which the Open-End Fund may sell multiple
classes of its shares with varying combinations of front-end service charges
(each a "FESC"), distributions fees, service fees, contingent deferred sales
charges (each a "CDSC"), exchange features, conversion rights, voting rights,
expenses allocations and investment requirements.  As used herein, classes of
shares of a Fund subject to a FESC will be referred to as FESC Shares, and
classes of shares of a Fund subject to a CDSC will be referred to as CDSC
Shares.

     24.(a)  With respect to any shares of a class of FESC Shares of an
Open-End Fund, the public offering price for such shares shall be the net asset
value per share plus a FESC, expressed as a percentage of the applicable public
offering price, as determined and effective as of the time specified in the
then-current Prospectus of such Open-End Fund.  On each order for shares of a
class of FESC Shares of an Open-End Fund accepted by us, you will be entitled
to receive the applicable agency commission for such shares as provided for in
the then-current Prospectus of such Open-End Fund or, if not so provided, as
provided to you from time to time in writing by VK Funds.

(b)  With respect to any shares of a class of CDSC Shares of an Open-End Fund,
the public offering price for such shares shall be the net asset value per
share as determined and effective as of the time specified in the then-current
Prospectus of such Open-End Fund.  You will remit payment of the aggregate
public offering price to VK Funds for the CDSC Shares sold, and on each order
accepted by us, you will be entitled to receive the applicable selling
compensation for such shares as 

                                      4
<PAGE>   5
provided for in the then-current Prospectus of such Open-End Fund or,
if not so provided, as provided to you from time to time in writing by VK Funds.

     25.  Should you wish to participate in the Distribution Plan with respect
to a class of shares adopted by an Open-End Fund pursuant to Rule 12b-1 ("Rule
12b-1 Plan") under the Investment Company Act of 1940, as amended, or the
Service Plan with respect to a class of shares, it is understood that you must
be approved by the Board of Directors of such Open-End Fund and execute a
Distribution Assistance Agreement.

     26.  With respect to the Open-End Funds, your acceptance of this Agreement
constitutes a representation that you will adopt policies and procedures to
comply with Rule 18f-3 under the Investment Company Act of 1940, with respect
to when you may appropriately make available the various classes of shares of
the Open-End Funds to investors and that you will make available such shares
only in accordance therewith.

     27.  You agree to make shares of an Open-End Fund available to your
customers only:  (i) at the applicable public offering price, (ii) from VK Funds
and (iii) to cover orders already received by you from your customers.  VK Funds
in turn agrees that it will not purchase any shares from an Open-End Fund except
for the purpose of covering purchase orders that it has already received.

     28.(a)  If any shares of a class of FESC Shares of an Open-End Fund sold
to your customers under the terms of this Agreement are repurchased by the Fund
or by VK Funds as agent for the Fund or are tendered for redemption within seven
business days after the date of VK Funds' confirmation of the original purchase,
it is agreed that you shall forfeit your right to any agency commission
received by you on such FESC Shares.  VK Funds will notify you of any such
repurchase or redemption within ten business days from the date on which the
repurchase or redemption order in proper form is delivered to VK Funds or to the
Fund, and you shall forthwith refund to VK Funds the full agency commission
allowed to you on such sale.  VK Funds agrees, in the event of any such
repurchase or redemption, to refund to the Fund its share of any discount
allowed to VK Funds and, upon receipt from you of the refund of the agency
commission allowed to you, to pay such refund forthwith to the Fund.

     (b)  If any shares of a class of CDSC Shares sold to your customers under
the terms of this Agreement are repurchased by the Fund or by VK Funds as agent
for the Fund or are tendered for redemption within seven business days after the
date of VK Funds' confirmation of the original purchase, it is agreed that you
shall forfeit your right to any sales compensation received by you on such CDSC
Shares.  We will notify you of any such repurchase or redemption within ten
business days from the date on which the repurchase or redemption order in
proper form is delivered to VK Funds or to the Fund, and you shall forthwith
refund to VK Funds the full sales compensation paid to you.

TERMS AND CONDITIONS APPLICABLE TO CLOSED END-FUNDS

     29.  No Closed-End Fund will issue fractional shares.

     30.  VK Funds may, in its sole discretion, allocate shares of a Closed-End
Fund among brokers, dealers and, if permitted by applicable laws, banks
participating in the Initial Offering Period or among brokers, dealers and
banks in the Continuous Offering Period, as the case may be, on other than a
pro rata basis, which may result in certain brokers, dealers and banks not
being allocated the full amount of shares of such Fund sold by them while
certain other brokers, dealers and banks may receive their full allocation.

     31.  You agree that with respect to orders for shares of a Closed-End
Fund, you will transmit such orders received during the Initial Offering Period
to VK Funds within the time period as specified in such Closed-End Fund's
Prospectus (or in the time period as extended by VK Funds in writing).  You also
agree to transmit any customer order received during the Continuous Offering
Period to VK Funds prior to the time that the public offering price for such
Closed-End Fund is next determined after your receipt of such order, as set
forth in the Closed-End Fund's Prospectus.  There is no assurance that each
Closed-End Fund will engage in a continuous offering of shares.

32.  On each order accepted by VK Funds for shares of a Closed-End Fund, you
will be entitled to receive a concession paid out of VK Funds' own assets as
set forth in the then-current Prospectus of such Closed-End Fund (exclusive of
additional compensation that may be payable pursuant to sales programs, if any,
that may be established from time to time as described in the Prospectus for
such Closed-End Fund, which will be payable only as and to the extent the
requirements


                                      5
<PAGE>   6
of such programs are satisfied).  In no event will any Closed-End Fund reimburse
VK Funds for any such sales concessions or other additional compensation or pay
any such concession or other additional compensation or allowance directly to
you.  VK Funds will specify for each Closed-End Fund a period after the date
that the shares of such Closed-End Fund are listed on the New York Stock
Exchange, the American Stock Exchange or another national securities market
system (which period will end no later than the first dividend payment date with
respect to such Closed-End Fund) during which sales concessions and other
additional compensation are subject to forfeiture as provided in the following
sentence (the "Forfeiture Period").  During the Forfeiture Period for any
Closed-End Fund, physical delivery of certificates representing shares will be
required to transfer ownership of such shares.  In the event that any shares of
a Closed-End Fund sold through an order received from you in the Initial
Offering Period or the Continuous Offering Period are resold in the open market
or otherwise during the Forfeiture Period, VK Funds reserves the right to
require you to forfeit any sales concessions and other additional compensation
with respect to such shares.  In the event of a forfeiture, VK Funds may
withhold any forfeited sales concessions and other additional compensation that
has not yet been paid or from other amounts yet to be paid to you (whether or
not payable with respect to such shares), and you agree to repay to VK Funds,
promptly upon demand, any forfeited sales concessions and other compensation
that has been paid. Determinations of the amounts to be paid to you or by you to
VK Funds shall be made by VK Funds and shall be conclusive.

     33.  During the Initial Offering Period and any Continuous Offering Period
for any Closed-End Fund, you agree to supply VK Funds, not less frequently than
once a week by Friday, 5:00 p.m. Eastern Time, during such Closed-End Fund's
Initial Offering Period, a list setting forth by state and in the aggregate all
indications of interest and, during any Continuous Offering Period, all shares
sold by you of such Closed-End Fund during such week (or lesser period of time)
and a list setting forth by name and location each registered representative
making said sales and indicating the amount of all sales per Closed-End Fund to
date.

     34.  You expressly acknowledge and understand that there is no Rule 12b-1
Plan for the Closed-End Funds.

     35.  You expressly acknowledge and understand that shares of the Closed-End
Funds will not be repurchased by either the Closed-End Funds (other than through
tender offers from time to time, if any) or by VK Funds and that no secondary
market for such shares is expected to develop until the shares have begun
trading on a national exchange or national market system.  You hereby covenant
that, until notified by VK Funds that the distribution of such shares has been
completed or that the Forfeiture Period has ended, you (a) will not make a
secondary market in any shares of such a Closed-End Fund, (b) will not purchase
or hold shares of such Closed-End Fund in inventory for the purpose of resale in
the open market or to your customers and, (c) without VK Funds' consent, will
not repurchase shares of such Closed-End Fund in the open market or from your
customers for any account in which you have a beneficial interest.

     36.  Unlike the other Closed-End Funds, the Continuous Offering period with
respect to the Van Kampen Prime Rate Income Trust (the "Prime Rate Fund") may
continue indefinitely.  The offer to make available to you shares of the Prime
Rate Fund is subject to further terms and conditions in addition to those set
out above, as follows:

     (a)  You expressly acknowledge and understand that shares of the Prime Rate
Fund will not be repurchased by either the Prime Rate Fund (other than through
tender offers from time to time, if any) or VK Funds and that no secondary
market for the shares of the Prime Rate Fund exists currently or is expected to
develop.  You also expressly acknowledge and agree that, in the event your
customer cancels their order for shares after confirmation, such shares may not
be repurchased, remarketed or otherwise disposed of by or through VK Funds.

     (b)  You acknowledge and understand that, while the Board of Trustees of
the Prime Rate Fund intends to consider tendering for all or a portion of the
Prime Rate Fund's shares on a quarterly basis, there is no assurance the Prime
Rate Fund will tender for shares at any time or, following such a tender offer,
that shares so tendered will be repurchased by the Prime Rate Fund.  You
acknowledge and understand that an early withdrawal charge payable to VK Funds
will be imposed on most shares accepted for tender by the Prime Rate Fund that
have been held for less than five years, as set forth in the Prime Rate Fund's
Prospectus.  ANY REPRESENTATION AS TO A TENDER OFFER BY


                                      6
<PAGE>   7
THE PRIME RATE FUND, OTHER THAN THAT WHICH IS SET FORTH IN THE PRIME RATE FUND'S
CURRENT PROSPECTUS, IS EXPRESSLY PROHIBITED.

Clearing Agreement, keeping a copy for your files and returning the original to

                    BANK FULLY DISCLOSED CLEARING AGREEMENT
                           WITH VAN KAMPEN FUNDS INC.
                              REGARDING VAN KAMPEN
                  OPEN-END AND CLOSED-END INVESTMENT COMPANIES


Ladies and Gentlemen:

     As dealer for our own account, we offer to make available to you shares of
any of the Van Kampen open-end investment companies (the "Open-End Funds" or,
individually, an "Open-End Fund") and Van Kampen Funds closed-end investment
companies (the "Closed-End Funds" or, individually, a "Closed-End Fund")
distributed by Van Kampen Funds, Inc. ("VK Funds") pursuant to the terms and
conditions contained herein.  Collectively, the Open-End Funds and Closed-End
Funds sometimes are referred to herein as the "Funds" or, individually, as a
"Fund".  You are a bank that desires to make available shares of such Funds to
your customers on a fully disclosed basis wherein VK Funds would confirm
transactions of your customers in a Fund directly to them.  You agree not to
make available shares of such Funds during any fixed price offering of such
shares.

     VK Funds acts as the principal underwriter (as such term is defined in the
Investment Company Act of 1940, as amended) for each Fund with respect to its
offering of one or more classes of shares as described in each Fund's
Prospectus.  Pursuant to this Agreement, VK Funds offers to make available to
you shares of each Open-End Fund and each Closed-End Fund prior to the Effective
Date (as defined herein) of each Fund's Registration Statement (as defined
herein) (the "Initial Offering Period"), to the extent permitted by applicable
law, and after the Effective Date of each Fund's Registration Statement (the
"Continuous Offering Period") (if any) as described in such Closed-End Fund's
Prospectus.

     As used herein unless otherwise indicated, the term "Prospectus" means the
final prospectus and Statement of Additional Information included in the
Registration Statement for the Fund on the Effective Date and as from time to
time thereafter amended or supplemented.  As used herein unless otherwise
indicated, the term "Preliminary Prospectus" means any preliminary prospectus
and any Statement of Additional Information included at any time as a part of
the Registration Statement for any Fund prior to the Effective Date and that is
authorized by VK Funds for use in connection with the offering of shares.

     In consideration of the mutual obligations contained herein, the
sufficiency of which is hereby acknowledged by you, the terms of the Agreement
are as follows:

GENERAL TERMS AND CONDITIONS

     1.  Your acceptance of this Agreement constitutes a representation that you
are a bank as defined in Section 3(a)(6) of the Securities Exchange Act of 1934,
as amended, and have been duly authorized to enter into this Agreement and
perform your obligations hereunder.  This Agreement as well as your authority to
make shares available to your customers will automatically terminate if you
shall cease to be a bank as defined above.  You agree not to offer or sell
shares of any Fund except through VK Funds.  You will not accept any orders from
any broker, dealer or financial institution who is purchasing from you with a
view toward distribution unless you have obtained such person's or entity's
written consent to be bound by the terms of this Agreement.

     2.  For the purposes of the Securities and Exchange Commission's Financial
Responsibility Rules and the Securities Investor's Protection Act, your
customers will be considered customers of VK Funds and not of your firm.  VK
Funds has been granted an exemption from the NASD rules of Fair Practice,
Article III Section 45 requirements to send customer statements and thus will
not do so. Customer statements showing account activity and balances will be
mailed to the customer by the Funds each time a financial transaction occurs in
their account and on a monthly or quarterly basis.  Nothing



                                      1
<PAGE>   2
herein shall cause your firm's customers to be interpreted as customers of VK
Funds for any other purpose, or to negate the intent of any other section of
this agreement, including, but not limited to, the delineation of
responsibilities as set forth elsewhere in this agreement.

     3.  In transactions where you make available shares of the Funds to the
public, you shall have no authority to act as agent for the Fund or for VK
Funds. The customers in question are for all purposes your customers and not
customers of VK Funds.  We will clear transactions for each of your customers
only upon your authorization, it being understood in all cases that (a) you are
acting as the agent for the customer; (b) the transactions are without recourse
against you by the customer except to the extent that your failure to transmit
orders in a timely fashion results in a loss to your customer; (c) as between
you and the customer, the customer will have full beneficial ownership of the
Fund shares; (d) each transaction is initiated solely upon the order of the
customer; and (e) each transaction is for the account of the customer and not
for your account.

     4.  Each Fund has filed with the Securities and Exchange Commission (the
"SEC") and the securities commissions of one or more states a Registration
Statement (the "Registration Statement") on the SEC form applicable to the
respective Fund.  The date on which the Registration Statement is declared
effective by the SEC is hereinafter referred to as the "Effective Date".  Prior
to the Effective Date of the Registration Statement with respect to a particular
Fund, you expressly acknowledge and understand that with respect to such Fund:
        
             (a)  Shares of such Fund may not be sold, nor may offers to buy be
accepted, (i) prior to the Effective Date of the Registration Statement or (ii)
in any state in which such offer or sale would be unlawful prior to registration
or qualification under the securities laws of such state.

             (b)  Except to the extent permitted by law, you will not solicit or
transmit to VK Funds any indications of interest to purchase shares during any
fixed-price offering.

             (c)  The Fund's Preliminary Prospectus, together with any sales
material distributed for use in connection with the offering of shares of such
Fund, does not constitute an offer to sell or the solicitation of an offer to
buy shares of such Fund and is subject to completion and modification by the
Prospectus.

             (d)  In the event and to the extent permitted by applicable law you
transmit indications of interest to VK Funds for accumulation prior to the
Effective Date, upon your instruction VK Funds will send confirmation of such
indications of interest directly to your customers in writing, together with
copies of the Preliminary Prospectus for the Fund, and send copies of the
confirmations to you.  Indications of interest with respect to shares of a class
of a Fund's shares transmitted to VK Funds prior to the Effective Date are
subject to acceptance or rejection by VK Funds in its sole discretion and are
conditioned upon the occurrence of (i) the Effective Date and (ii) the
registration or qualification of the respective class of shares in the
respective state.

             (e)  Indications of interest with respect to shares of a class of a
Fund's shares not canceled by you prior to or on the later of (i) the Effective
Date and (ii) the registration or qualification of the respective class of
shares in the respective state, and accepted by VK Funds will be deemed by VK
Funds to be orders for Shares solely to the extent permitted by applicable law.

             (f)  Upon your instruction, VK Funds will send confirmations of
orders accepted by VK Funds (including indications of interest deemed orders)
directly to your customers in writing, together with copies of the Prospectus
for the Fund, and send copies of the confirmations to you.

             (g)  Upon receipt of duplicate confirmations you will examine the
same and promptly notify VK Funds of any errors or discrepancies that you
discover and will promptly bring to VK Funds' attention any errors in such
confirmations claimed by your customers.  All confirmations to your customers
will indicate that orders were placed on a fully disclosed basis.

             (h)  All indications of interest and orders transmitted to VK Funds
are subject to the terms and conditions of the Fund's Prospectus and this
Agreement and are subject to acceptance or rejection by VK Funds in its sole
discretion.


                                      2

<PAGE>   3

     5.  After the Effective Date, you will not make shares of a class of the
Fund's shares available in any state where they are not qualified for sale
under the "blue sky" laws and regulations of such state, except for states in
which they are exempt from qualification.

     6.  In the event that you make shares of the Fund available outside the
United States, you agree to comply with the applicable laws, rules and
regulations of the foreign government having jurisdiction over such sales,
including any regulations of the United States military authorities applicable
to solicitations to military personnel.

     7.  Upon application to VK Funds, VK Funds will inform you as to the
jurisdictions in which VK Funds believes shares of a Fund have been qualified
for sale under the respective securities or "blue sky" laws of such
jurisdictions.  VK Funds understands and agrees that qualification of any shares
of a Fund for sale in such jurisdictions shall be solely VK Funds'
responsibility and that you assume no responsibility or obligation with respect
to such eligibility.  You understand and agree that your compliance with the
requirements of the securities or "blue sky" laws in each jurisdiction with
respect to your right to make the shares available in such jurisdiction shall be
solely your responsibility.

     8.  No person is authorized to make any representations concerning any
class of shares of a Fund except those contained in the Fund's current
Preliminary Prospectus or Prospectus, as the case may be.  In purchasing shares
from us you shall rely solely on the representations contained in such
Prospectus.  VK Funds will furnish additional copies of a Fund's current
Prospectus and sales literature issued by VK Funds in reasonable quantities
upon request.

     9.  You agree that you will distribute to the public only (i) the
Prospectus and any amendment or supplement thereto and (ii) sales literature or
other documents expressly authorized for such distribution by VK Funds.

     10.  Orders received from you will be accepted by VK Funds only at the
public offering price applicable to each order as specified in the then-current
Fund Prospectus.  The minimum dollar purchase of any shares of each Fund by any
person shall be the applicable minimum dollar amount described in the
then-current Fund Prospectus for that class of shares, and no order for less
than such amount will be accepted hereunder.  The procedures relating to the
handling of orders shall be subject to instructions that VK Funds shall
communicate from time to time to you.  All orders are subject to acceptance
or rejection by VK Funds in its sole discretion.  Upon acceptance of an order,
we shall confirm directly to the customer in writing upon your instruction and
send a copy of the confirmation to you.  In addition, we will send a Fund
Prospectus with the confirmation.  You agree that upon receipt of duplicate
confirmations you will examine the same and promptly notify VK Funds of any
errors or discrepancies that you discover and shall promptly bring to VK Funds'
attention any errors in such confirmations claimed by your customers.  All
confirmations to your customers will indicate that orders were placed on a fully
disclosed basis.

     11.  Payment for Fund shares shall be made on or before the settlement
date specified in the VK Funds confirmation at the office of VK Funds' clearing
agent, or wire to the order of the Fund which reserves VK Funds' right to delay
issuance or transfer of shares until such check has cleared.  If such payment
is not received by VK Funds, VK Funds reserves the right, without notice,
forthwith either to cancel the trade at our option or as required by the
provisions of Regulation T, and in either case, VK Funds may hold you
responsible for any loss suffered by the Fund.  You agree that in transmitting
investors' funds, you will comply with Rule 15c2-4 under the Securities Exchange
Act of 1934, as amended.

     12.  You shall not withhold placing orders with VK Funds from your
customers so as to profit yourself as a result of such withholding; e.g., by
a change in the net asset value from that used in determining the public
offering price to your customers.

     13.  VK Funds will not accept from you any conditioned orders for shares,

TERMS AND CONDITIONS APPLICABLE TO OPEN-END FUNDS

     23.  Each of the Open-End Funds is subject to an alternative distribution
plan (the "Alternative Distribution Plan") as described in such Fund's
then-current Prospectus pursuant to which the Open-End Fund may sell multiple
classes of its shares with varying combinations of front-end service charges
(each a "FESC"), distributions fees, service fees, contingent deferred sales
charges (each a "CDSC"), exchange features, conversion rights, voting rights,
expenses allocations and investment requirements.  As used herein, classes of
shares of a Fund subject to a FESC will be referred to as FESC Shares, and
classes of shares of a Fund subject to a CDSC will be referred to as CDSC
Shares.

     24.  (a)  With respect to any shares of a class of FESC Shares of an
Open-End Fund, the public offering price for such shares shall be the net asset
value per share plus a FESC, expressed as a percentage of the applicable public
offering price, as determined and effective as of the time specified in the
then-current Prospectus of such Open-End Fund.  On each order for shares of a
class of FESC Shares of an Open-End Fund accepted by us, you will be entitled
to receive the applicable agency commission for such shares as provided for in
the then-current Prospectus of such Open-End Fund or, if not so provided, as
provided to you from time to time in writing by VK Funds.




                                      4

<PAGE>   5
     (b)  With respect to any shares of a class of CDSC Shares of an Open-End
Fund, the public offering price for such shares shall be the net asset value per
share as determined and effective as of the time specified in the then-current
Prospectus of such Open-End Fund.  You will remit payment of the aggregate
public offering price to VK Funds for the CDSC Shares sold, and on each order
accepted by us, you will be entitled to receive the applicable selling
compensation for such shares as provided for in the then-current Prospectus of
such Open-End Fund or, if not so provided, as provided to you from time to time
in writing by VK Funds.

     25.  Should you wish to participate in the Distribution Plan with respect
to a class of shares adopted by an Open-End Fund pursuant to Rule 12b-1 ("Rule
12b-1 Plan") under the Investment Company Act of 1940, as amended, or the
Service Plan with respect to a class of shares, it is understood that you must
be approved by the Board of Directors of such Open-End Fund and execute an
Administrative Service Agreement.

     26.  With respect to the Open-End Funds, your acceptance of this Agreement
constitutes a representation that you will adopt policies and procedures to
comply with Rule 18f-3 under the Investment Company Act of 1940, with respect
to when you may appropriately make available the various classes of shares of
the Open-End Funds to investors and that you will make available such shares
only in accordance therewith.

     27.  You agree to make shares of an Open-End Fund available to your
customers only:  (i) at the applicable public offering price, (ii) from VK Funds
and (iii) to cover orders already received by you from your customers.  VK Funds
in turn agrees that it will not purchase any shares from an Open-End Fund except
for the purpose of covering purchase orders that it has already received.

     28.  (a)  If any shares of a class of FESC Shares of an Open-End Fund sold
to your customers under the terms of this Agreement are repurchased by the Fund
or by VK Funds as agent for the Fund or are tendered for redemption within seven
business days after the date of VK Funds' confirmation of the original purchase,
it is agreed that you shall forfeit your right to any agency commission received
by you on such FESC Shares.  VK Funds will notify you of any such repurchase or
redemption within ten business days from the date on which the repurchase or
redemption order in proper form is delivered to VK Funds or to the Fund, and you
shall forthwith refund to VK Funds the full agency commission allowed to you on
such sale.  VK Funds agrees, in the event of any such repurchase or redemption,
to refund to the Fund its share of any discount allowed to VK Funds and, upon
receipt from you of the refund of the agency commission allowed to you, to pay
such refund forthwith to the Fund.

           (b)  If any shares of a class of CDSC Shares sold to your customers 
under the terms of this Agreement are repurchased by the Fund or by VK Funds as 
agent for the Fund or are tendered for redemption within seven business days 
after the date of VK Funds' confirmation of the original purchase, it is agreed 
that you shall forfeit your right to any sales compensation received by you on 
such CDSC Shares.  We will notify you of any such repurchase or redemption 
within ten business days from the date on which the repurchase or redemption 
order in proper form is delivered to VK Funds or to the Fund, and you shall 
forthwith refund to VK Funds the full sales compensation paid to you.

TERMS AND CONDITIONS APPLICABLE TO CLOSED END-FUNDS

     29.  No Closed-End Fund will issue fractional shares.

     30.  VK Funds may, in its sole discretion, allocate shares of a Closed-End
Fund among brokers, dealers and, to the extent permitted by applicable law,
banks participating in the Initial Offering Period or among brokers, dealers and
banks participating in the Continuous Offering Period, as the case may be, on
other than a pro rata basis, which may result in certain brokers, dealers and
banks not being allocated the full amount of shares of such Fund sold by them
while certain other brokers, dealers and banks may receive their full
allocation.

     31.  You agree that with respect to orders for shares of a Closed-End Fund,
you will transmit such orders received, to the extent permitted by applicable
law, during the Initial Offering Period to VK Funds within the time period as
specified in such Closed-End Fund's Prospectus (or in the time period as
extended by VK Funds in writing).  You also agree to transmit any customer order
received during the 


                                      5

<PAGE>   6
Continuous Offering Period to VK Funds prior to the time that the public 
offering price for such Closed-End Fund is next determined after your receipt
of such order, as set forth in the Closed-End Fund's Prospectus. There is
no assurance that each Closed-End Fund will engage in a continuous offering of 
shares.

     32.  On each order accepted by VK Funds for shares of a Closed-End
Fund,  you will be entitled to receive a concession paid out of VK Funds' own
assets as  set forth in the then-current Prospectus of such Closed-End Fund
(exclusive of additional compensation that may be payable pursuant to sales
programs, if any, that may be established from time to time as described in the
Prospectus for such Closed-End Fund, which will be payable only as and to the
extent the requirements of such programs are satisfied).  In no event will any
Closed-End Fund reimburse VK Funds for any such sales concessions or other
additional compensation or pay any such concession or other additional
compensation or allowance directly to you.  VK Funds will specify for each
Closed-End Fund a period after the date that the shares of such Closed-End Fund
are listed on the New York Stock Exchange, the American Stock Exchange or
another national securities market system (which period will end no later than
the first dividend payment date with respect to such Closed-End Fund) during
which sales concessions and other additional compensation are subject to
forfeiture as provided in the following sentence (the "Forfeiture Period"). 
During the Forfeiture Period for any Closed-End Fund, physical delivery of
certificates representing shares will be required to transfer ownership of such
shares.  In the event that any shares of a Closed-End Fund sold through an
order received from you, to the extent permitted by applicable law, in the
Initial Offering Period or the Continuous Offering Period are resold in the
open market or otherwise during the Forfeiture Period, VK Funds reserves the
right to require you to forfeit any sales concessions and other additional
compensation with respect to such shares.  In the event of a forfeiture, VK
Funds may withhold any forfeited sales concessions and other additional
compensation that has not yet been paid or from other amounts yet to be paid to
you (whether or not payable with respect to such shares), and you agree to
repay to VK Funds, promptly upon demand, any forfeited sales concessions and
other compensation that has been paid.  Determinations of the amounts to be
paid to you or by you to VK Funds shall be made by VK Funds and shall be
conclusive.

     33.  During the Initial Offering Period or any Continuous Offering Period
for any Closed-End Fund, you agree to supply VK Funds, not less frequently than
once a week by Friday, 5:00 p.m. Eastern Time, during such Closed-End Fund's
Initial Offering Period, a list setting forth by state and in the aggregate all
indications of interest and, during any Continuous Offering Period, all shares
sold by you of such Closed-End Fund during such week (or lesser period of time)
and a list setting forth by name and location each registered representative
making said sales and indicating the amount of all sales per Closed-End Fund to
date.

     34.  You expressly acknowledge and understand that there is no Rule 12b-1
Plan for the Closed-End Funds.

     35.  You expressly acknowledge and understand that shares of the Closed-End
Funds will not be repurchased by either the Closed-End Funds (other than through
tender offers from time to time, if any) or by VK Funds and that no secondary
market for such shares is expected to develop until the shares have begun
trading on a national exchange or national market system.  You hereby covenant
that, until notified by VK Funds that the distribution of such shares has been
completed or that the Forfeiture Period has ended, you (a) will not make a
secondary market in any shares of such a Closed-End Fund, (b) will not purchase
or hold shares of such Closed-End Fund in inventory for the purpose of resale in
the open market or to your customers and, (c) without VK Funds' consent, will
not repurchase shares of such Closed-End Fund in the open market or from your
customers for any account in which you have a beneficial interest.

     36.  Unlike the other Closed-End Funds, the Continuous Offering period with
respect to the Van Kampen Prime Rate Income Trust (the "Prime
Rate Fund") may continue indefinitely.  The offer to make available to you
shares of the Prime Rate Fund is subject to further terms and conditions in
addition to those set out above, as follows:

             (a)  You expressly acknowledge and understand that shares of the
Prime Rate Fund will not be repurchased by either the Prime Rate Fund (other
than through tender offers from time to time, if any) or VK Funds and that no
secondary market for the shares of the Prime Rate Fund exists currently or is
expected to develop.  You also expressly acknowledge and agree that, in the
event your 

                                      6

<PAGE>   7

customer cancels their order for shares after confirmation, such
shares may not be repurchased, remarketed or otherwise disposed of by or
through VK Funds.

              (b)  You acknowledge and understand that, while the Board of
Trustees of the Prime Rate Fund intends to consider tendering for all or a
portion of the  Prime Rate Fund's shares on a quarterly basis, there is no
assurance the Prime Rate Fund will tender for shares at any time or, following
such a tender offer, that shares so tendered will be repurchased by the Prime
Rate Fund.  You acknowledge and understand that an early withdrawal charge
payable to VK Funds will be imposed on most shares accepted for tender by the
Prime Rate Fund that have been held for less than five years, as set forth in
the Prime Rate Fund's Prospectus.  ANY REPRESENTATION AS TO A TENDER OFFER BY
THE PRIME RATE FUND, OTHER THAN THAT WHICH IS SET FORTH IN THE PRIME RATE FUND'S
CURRENT PROSPECTUS, IS EXPRESSLY PROHIBITED.

     Please accept the foregoing by signing this Bank Fully Disclosed Clearing
Agreement, keeping a copy for your files and returning the original to us.

               Re:     Van Kampen Prime Rate Income Trust
                       Registration Statement on Form N-2

Ladies and Gentlemen:

     We have acted as special counsel to Van Kampen Prime Rate Income Trust (the
"Fund"), a voluntary association with transferable shares organized and existing
under and by virtue of the laws of the Commonwealth of Massachusetts (a
"Massachusetts Business Trust"), in connection with the preparation of the
Fund's Registration Statement on Form N-2 (the "Registration Statement") under
the Securities Act of 1933, as amended (the "1933 Act"), and the Investment
Company Act of 1940, as amended (the "1940 Act"), which will be filed by the
Fund with the Securities and Exchange Commission (the "Commission") on or about
April 8, 1999. The Registration Statement relates to the registration under the
1933 Act of the number of common shares of beneficial interest, par value of
$.01 per share, of the Fund named therein (the "Common Shares").

     The Common Shares are to be sold pursuant to an offering agreement (the 
"Offering Agreement") between the Fund and Van Kampen Funds Inc. (formerly known
as Van Kampen American Capital Distributors, Inc.).

     This opinion is delivered in accordance with the requirements of Item 
24(2)(1) of Form N-2 under the 1933 Act and 1940 Act.

     In connection with this opinion, we have examined originals or copies, 
certified or otherwise identified to our satisfaction, of (i) the Registration


<PAGE>   2

April 8,1999
Page 2


   
Statement, (ii) the Declaration of Trust and By-Laws of the Fund (the
"Declaration of Trust" and "By-Laws", respectively), (iii) the Offering
Agreement between the Fund and Van Kampen Funds Inc., (iv) resolutions adopted
by the Board of Trustees of the Fund pursuant to an action by written consent,
dated as of March 26, 1999, with respect to the filing of the Registration
Statement, the offer and issuance of the Common Shares and other related matters
(the "Resolutions") and (v) such other documents as we have deemed necessary or
appropriate as a basis for the opinion set forth herein. In such examination, we
have assumed the genuineness of all signatures, the legal capacity of natural
persons, the authenticity of all documents submitted to us as originals, the
conformity to original documents of all documents submitted to us as certified,
conformed or photostatic copies and the authenticity of the originals of such
copies. As to any facts material to the opinion expressed herein which we have
not independently established or verified, we have relied upon statements and
representations of officers and other representatives of the Fund.
    

     Members of our firm are admitted to the Bar in the Commonwealth of
Massachusetts, and we express no opinion as to the laws of any other
jurisdiction.

     Based upon and subject to the foregoing, we are of the opinion that when
(i) the Registration Statement shall have become effective, and (ii)
certificates for the Common Shares have been duly executed, countersigned,
registered, delivered and paid for in accordance with the Offering Agreement,
the Common Shares will be duly authorized, validly issued, fully paid and,
subject to the statements set forth below regarding the liability of a
shareholder of a Massachusetts Business Trust, nonassessable.

     Pursuant to certain decisions of the Supreme Judicial Court of
Massachusetts, shareholders of a Massachusetts Business Trust may, in certain
circumstances, be assessed or held personally liable as partners for the
obligations of the Fund.  Even if the Fund were held to be a partnership, 
however, the possibility of the holders of Common Shares incurring personal
liability for financial losses of the Fund appears remote because (i) Article V,
Section 5.1 of the Declaration of Trust contains an express disclaimer of
liability for holders of Common Shares for the obligations of the Fund and
provides that the Fund shall hold each holder of Common Shares harmless from,
and shall indemnify such holder against, all loss and


<PAGE>   3

April 8, 1999
Page 3




expense arising solely from being or having been a holder of Common Shares and
(ii) Article V, Section 5.5 requires that a recitation of such disclaimer be
included in every written obligation, contract, instrument, certificate, common
share of beneficial interest, other security of the Fund or undertaking made or
issued by the trustees of the Fund.

     We hereby consent to the filing of this opinion with the Commission as
Exhibit (1) to the Registration Statement. We also consent to the reference to
our firm under the heading "Legal Opinions" in the Registration Statement. In
giving this consent, we do not thereby admit that we are in the category of
persons whose consent is required under Section 7 of the 1933 Act or the rules
and regulations of the Commission.

                                   Very truly yours,
