 SHAREHOLDERS TO VOTE ON MONTHLY REPURCHASE POLICY, CHANGES TO BORROWING POLICY
        AND THE ELECTION OF NEW TRUSTEES FOR VAN KAMPEN SENIOR LOAN FUND

At Van Kampen Investments, we believe a commitment to excellence is essential
for consistent, long-term success. Rigorous evaluation of our product line--with
an eye toward the overall competitive landscape--is, therefore, a vital part of
our management process.

Toward this end, the Board of Trustees of the Van Kampen Senior Loan Fund (the
"Fund") recently approved several changes to the Fund. These changes are
described in a proxy statement being sent to the shareholders of the Fund. As
described in the proxy statement, shareholders are being asked to vote to
increase the frequency of the repurchase offers from quarterly to monthly, to
approve changes to the Fund's borrowing policy in order to provide for the
ability to use financial leverage for investment purposes and to nominate five
new trustees to the Board of Trustees.

Here is some information on these changes:

     CHANGE THE QUARTERLY REPURCHASE OFFERS TO MONTHLY REPURCHASE OFFERS
     Currently, the Fund makes quarterly offers to repurchase its shares. The
     Board of Trustees has approved changing the Fund's current quarterly
     repurchase policy to one where the Fund would make monthly offers to
     repurchase its shares and has filed an exemptive application with the
     Securities and Exchange Commission (the "SEC") to permit such a policy
     change.

     The Board of Trustees and the Fund's investment adviser believe that
     monthly repurchase offers may provide shareholders with increased
     liquidity, potentially better management of investments and better planning
     of transactions. Rather than planning for liquidity months in advance,
     shareholders would be able to liquidate their shares on a monthly basis.

     If the Fund obtains exemptive relief from the SEC, and if shareholders
     approve the changes, the Fund would provide notification to shareholders of
     an upcoming monthly repurchase offer at least seven calendar days in
     advance of the repurchase request deadline. The Fund anticipates that each
     repurchase offer will be up to 5% of shares outstanding on the repurchase
     request deadline. Shareholders are referred to the proxy materials for a
     complete description of this proposal as well as the potential benefits and
     costs associated with monthly repurchase offers.


     FINANCIAL LEVERAGE
     The Board approved a measure that will allow the Fund to utilize financial
     leverage to the maximum extent permitted under applicable law and to use
     such leverage to purchase additional portfolio securities. The Fund
     currently employs borrowings only to provide the Fund with additional
     liquidity to meet its obligations to



     repurchase its shares pursuant to its repurchase offers (and does not
     purchase additional portfolio securities at any time that borrowings exceed
     5% of the Fund's total assets). The Board of Trustees and the Fund's
     investment adviser believe that the use of financial leverage for
     investment purposes may provide the Fund with several potential benefits
     including enhanced income and distributions to shareholders, increased
     investment flexibility, additional investment capital and a more
     competitive fund structure similar to other closed-end funds in the
     marketplace. Generally speaking, if the Fund can invest the proceeds from
     financial leverage (i.e., money from borrowings or issuing preferred
     shares) in portfolio securities that have higher rates of return than the
     costs of such financial leverage and other expenses of the Fund, then the
     holders of common shares would have a net benefit. Shareholders are
     referred to the proxy materials for a complete description of this proposal
     as well as other potential benefits and the risks associated with leverage.

     ELECT 5 NEW TRUSTEES
     The business and affairs of the Fund are managed under the direction of the
     Fund's Board of Trustees. The Board is proposing to combine the Trustees of
     the Fund with the Trustees/Directors of boards of other Van Kampen funds.
     The incumbent Trustees believe that the addition of five new Trustees will
     create efficiencies and improve the effectiveness of the oversight of the
     Fund and other Van Kampen products.

Shareholders will receive the proxy materials related to all of these proposals
in May and are asked to vote at a shareholder meeting scheduled for June, 23
2006.
