PROXY STATEMENT VAN KAMPEN SENIOR INCOME TRUST 1221 AVENUE OF THE AMERICAS NEW YORK, NEW YORK 10020 TELEPHONE (800) 341-2929 ANNUAL MEETING OF SHAREHOLDERS JUNE 23, 2006 ------------------------------------------------------------------------------ INTRODUCTION ------------------------------------------------------------------------------ This Proxy Statement is furnished in connection with the solicitation by the Board of Trustees (the "Trustees" or the "Board") of the Van Kampen Senior Income Trust (the "Fund") of proxies to be voted at an Annual Meeting of Shareholders of the Fund, and all adjournments thereof (the "Meeting"), to be held at the offices of Van Kampen Investments Inc., 1 Parkview Plaza, Oakbrook Terrace, Illinois 60181-5555, on Friday, June 23, 2006, at 9:30 a.m. The Meeting will be an annual meeting for the Fund. The approximate mailing date of this Proxy Statement and accompanying form of proxy is May 24, 2006. Participating in the Meeting are holders of common shares of beneficial interest (the "Common Shares") and the holders of preferred shares of beneficial interest (the "Preferred Shares") of the Fund. The Common Shares and the Preferred Shares of the Fund are sometimes referred to herein as the "Shares." The purpose of the Meeting is to permit holders of the Fund's Common Shares to elect six Trustees and the holders of the Fund's Preferred Shares to elect one Trustee. The Board has fixed the close of business on May 12, 2006 as the record date (the "Record Date") for the determination of holders of Common Shares and holders of Preferred Shares of the Fund entitled to vote at the Meeting. Shareholders of the Fund on the Record Date are entitled to one vote per Share with respect to any proposal submitted to the shareholders of the Fund, with no Share having cumulative voting rights. At the close of business on May 12, 2006, there were issued and outstanding 180,010,000 Common Shares and 28,000 Preferred Shares of the Fund. THE FUND WILL FURNISH, WITHOUT CHARGE, A COPY OF ITS MOST RECENT ANNUAL REPORT AND SEMI-ANNUAL REPORT TO ANY SHAREHOLDER UPON REQUEST. ANY SUCH REQUEST SHOULD BE DIRECTED TO THE FUND BY CALLING 1-800-341-2929 (TDD USERS MAY CALL 1-800-421-2833) OR BY WRITING TO THE FUND AT 1 PARKVIEW PLAZA, PO BOX 5555, OAKBROOK TERRACE, ILLINOIS 60181-5555. VOTING AND SHAREHOLDER APPROVAL With respect to Proposal 1(a) through (c), as described in the Notice, holders of Common Shares and Preferred Shares will vote as separate classes for the respective nominee(s) to be elected by such class of shares. The affirmative vote of a plurality of the Common Shares of the Fund present at the Meeting in person or by proxy is required to elect each nominee for Trustee of the Fund designated to be elected by the holders of the Common Shares of the Fund. The affirmative vote of a plurality of the Preferred Shares of a Fund present at the Meeting in person or by proxy is required to elect such nominee for Trustee of the Fund designated to be elected by the holders of the Preferred Shares of the Fund. Election by plurality means those persons who receive the highest number of votes cast "FOR" up to the total number of persons to be elected as Trustees at the Meeting shall be elected. There is no cumulative voting with respect to the election of Trustees. THE BOARD OF TRUSTEES OF THE FUND RECOMMENDS THAT YOU CAST YOUR VOTE "FOR ALL" OF THE NOMINEES FOR THE BOARD OF TRUSTEES LISTED IN THE PROXY STATEMENT. All properly executed proxies received prior to the Meeting will be voted at the Meeting in accordance with the instructions marked thereon. Proxies received prior to the Meeting on which no vote is indicated will be voted "FOR" each proposal as to which they are entitled to be voted. Abstentions and broker non-votes (i.e., where a nominee such as a broker, holding shares for beneficial owners, indicates that instructions have not been received from the beneficial owners, and the nominee does not exercise discretionary authority) are not treated as votes "FOR" a proposal. With respect to the election of Trustees, abstentions and broker non-votes are disregarded since only votes "FOR" are considered in a plurality voting requirement. A majority of the outstanding Shares of the Fund entitled to vote must be present in person or by proxy to have a quorum for the Fund to conduct business at the Meeting. Abstentions and broker non-votes will be deemed present for quorum purposes. Shareholders who execute proxies may revoke them at any time before they are voted by filing with the Fund a written notice of revocation, by delivering a duly executed proxy bearing a later date or by attending the Meeting and voting in person. The Fund knows of no business other than the election of Trustees that will be presented for consideration at the Meeting. If any other matters are properly presented, it is the intention of the persons named on the enclosed proxy to vote proxies in accordance with their best judgment. In the event a quorum is present at the Meeting but sufficient votes to approve any of the proposals are not received, proxies (including abstentions and broker non-votes) would be voted in favor of one or more adjournments of the Meeting to permit further solicitation of proxies, provided they determine that such an adjournment and additional solicitation is reasonable and in the interest of 2 shareholders based on a consideration of all relevant factors, including the nature of the relevant proposal, the percentage of votes then cast, the percentage of negative votes then cast, the nature of the proposed solicitation activities and the nature of the reasons for such further solicitation. INVESTMENT ADVISER Van Kampen Asset Management serves as investment adviser to the Fund (the "Adviser"). The principal business address of the Adviser is 1221 Avenue of the Americas, New York, New York 10020. The Adviser is a wholly owned subsidiary of Van Kampen Investments Inc. ("Van Kampen"). Van Kampen is one of the nation's largest investment management companies, with more than $111 billion in assets under management or supervision as of April 30, 2006. Van Kampen is a wholly owned subsidiary of Morgan Stanley. OTHER SERVICE PROVIDERS The Fund has entered into an administration agreement and a legal services agreement with Van Kampen. Van Kampen's principal business address is 1221 Avenue of the Americas, New York, New York 10020. ------------------------------------------------------------------------------ BACKGROUND ON PROPOSAL 1 ------------------------------------------------------------------------------ NOMINATION OF TRUSTEES The business and affairs of the Fund are managed under the direction of the Fund's Board of Trustees. The tables below list the five incumbent Trustees and five new nominees for Trustee. A Trustee serves until reaching his/her retirement age or until a successor has been duly elected and qualified. All nominees have consented to being named in this Proxy Statement and have agreed to serve if elected. Five new Trustees are to be elected at the Meeting. Holders of Common Shares will vote with respect to five new nominees: Jerry D. Choate (as a Class I Trustee), Linda Hutton Heagy (as a Class II Trustee), R. Craig Kennedy (as a Class III Trustee), Jack E. Nelson (as a Class III Trustee) and Suzanne H. Woolsey (as a Class I Trustee). It is the intention of the persons named in the enclosed proxy to vote the Common Shares represented by them for the election of the respective nominees listed unless the proxy is marked otherwise. The five new nominees for Trustee proposed for the Fund reflect an effort to combine the Trustees of the Fund with the Trustees/Directors of boards of other Van Kampen funds managed by the Adviser. The incumbent Trustees of the Fund already serve as Trustees of the Fund and Trustees/Directors of these other Van Kampen funds; the five new nominees already serve as Trustees/Directors of other Van Kampen funds and seek shareholder election at this Meeting to serve as 3 Trustees of the Fund. The incumbent Trustees (and the nominees) believe that the addition of these five new Trustees will create efficiencies and improve the effectiveness of the Trustees' oversight of the Fund, as well as other Van Kampen funds, and the funds' management. The incumbent Trustees reviewed shareholder benefits and costs (as well as benefits and costs to the management company) of combining the Trustees/Directors of other Van Kampen funds into one board versus other alternatives to one board, including maintaining the status quo. The incumbent Trustees reviewed shareholder benefits in light of the changing environment for corporate governance. The incumbent Trustees considered the benefits of a combined board to include, among other things: increased number of independent board members compared to interested board members; greater efficiency and effectiveness in overseeing similarly-situated funds and service providers; broader experience, knowledge, diversity and expertise among board members; experienced board members at future retirements of other board members; and improved efficiencies among management resources. The incumbent Trustees considered their goals on behalf of the Fund in pursuing a combination, their current relationship with management and the anticipated post-combination relationship with management, the qualitative and quantitative effects of a board combination on the Trustees, and efficiencies and improved effectiveness that may be achieved at the Fund level, board level, management level and among third-party service providers. After reviewing these considerations, the incumbent Trustees concluded that addition of these five new Trustees is likely to benefit the shareholders of the Fund. As discussed below, if the nominees are elected, the existing committees of the Board may be changed to better align the Board committees of the Fund with the Board committees of other Van Kampen funds. As in the past, only one class of incumbent Trustees is being submitted to shareholders of the Fund for election at the Meeting, however, all of the new nominees for Trustees are being submitted to shareholders of the Fund for election at the Meeting. The Declaration of Trust of the Fund provides that the Board of Trustees shall consist of Trustees divided into three classes, the classes to be as nearly equal in number as possible. The Trustees of only one class are elected at each annual meeting so that the regular term of only one class of Trustees will expire annually and any particular Trustee stands for election only once in each three-year period. Consistent with the foregoing, only one class of incumbent Trustees is up for election for the Fund; however, each of the new nominees for Trustee is up for election this year with staggered terms so that the new Trustees are divided into the existing three classes as nearly equal in number as possible. This type of classification may prevent replacement of a majority of Trustees of the Fund for up to a two-year period. The foregoing is subject to the provisions of the Investment Company Act of 1940, as amended (the "1940 Act"), Massachusetts state law, the Fund's Declaration of Trust and the Fund's Bylaws. 4 ------------------------------------------------------------------------------ PROPOSAL 1: ELECTION OF TRUSTEES ------------------------------------------------------------------------------ Trustees are to be elected by shareholders at the Meeting in the following manner: (a) two Class I Trustees are to be elected at the Meeting, each to serve until the later of the Fund's Annual Meeting of Shareholders in 2008 or until a successor has been duly elected and qualified. Holders of Common Shares will vote with respect to two Class I Trustees: Jerry D. Choate and Suzanne H. Woolsey. It is the intention of the persons named in the enclosed proxy to vote the Shares represented by them for the election of the respective nominees listed unless the proxy is marked otherwise. (b) three Class II Trustees are to be elected at the Meeting, each to serve until the later of the Fund's Annual Meeting of Shareholders in 2009 or until a successor has been duly elected and qualified. Holders of Common Shares, voting as a separate class, will vote with respect to two Class II Trustees designated to be elected by such class of shares: Linda Hutton Heagy and Wayne W. Whalen. Holders of Preferred Shares, voting as a separate class, will vote with respect to one Class II Trustee designated to be elected by such class of shares: Rod Dammeyer. It is the intention of the persons named in the enclosed proxy to vote the Shares represented by them for the election of the respective nominees listed unless the proxy is marked otherwise. (c) two Class III Trustees are to be elected at the Meeting, each to serve until the later of the Fund's Annual Meeting of Shareholders in 2007 or until a successor has been duly elected and qualified. Holders of Common Shares, voting as a separate class, will vote with respect to two Class III Trustees designated to be elected by such class of shares: Jack E. Nelson and R. Craig Kennedy. It is the intention of the persons named in the enclosed proxy to vote the Shares represented by them for the election of the respective nominees listed unless the proxy is marked otherwise. 5 INFORMATION REGARDING INCUMBENT TRUSTEES AND NOMINEES FOR ELECTION AS TRUSTEE The tables below list the incumbent Trustees and nominees for Trustee, their principal occupations during the last five years, other directorships held by them and their affiliations, if any, with the Adviser, Van Kampen Funds Inc., Van Kampen Advisors Inc., Van Kampen Exchange Corp. and Van Kampen Investor Services, Inc.

N/A--Not applicable to nominees for Trustees. * Mr. Whalen is an interested person of funds in the Fund Complex by reason of he and his firm currently providing legal services as legal counsel to such funds in the Fund Complex. ** Messrs. Dammeyer and Sonnenschein are elected by the holders of the Fund's Preferred Shares. 12 REMUNERATION OF TRUSTEES The compensation of Trustees and executive officers who are affiliated persons (as defined in 1940 Act) of the Adviser or Van Kampen is paid by the respective affiliated entity. The funds in the Fund Complex, including the Fund, pay the non-affiliated Trustees an annual retainer and meeting fees. Each fund in the Fund Complex (except the Van Kampen Exchange Fund) provides a deferred compensation plan to its non-affiliated Trustees that allows such Trustees to defer receipt of compensation and earn a return on such deferred amounts based upon the return of the common shares of the funds in the Fund Complex as selected by the respective non-affiliated Trustees. Each fund in the Fund Complex (except the Van Kampen Exchange Fund) also provides a retirement plan to its non-affiliated Trustees that provides non-affiliated Trustees with compensation after retirement, provided that certain eligibility requirements are met as more fully described below. Each non-affiliated Trustee generally can elect to defer receipt of all or a portion of the compensation earned by such non-affiliated Trustee until retirement. Amounts deferred are retained by the respective fund and earn a rate of return determined by reference to the return on the common shares of such fund or other funds in the Fund Complex as selected by the respective non-affiliated Trustee, with the same economic effect as if such non-affiliated Trustee had invested in one or more funds in the Fund Complex, including the Funds. To the extent permitted by the 1940 Act, the Fund may invest in securities of those funds selected by the non-affiliated Trustees 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. The Fund has adopted a retirement plan. Under the retirement plan, a non-affiliated Trustee who is receiving Trustee's compensation from the Fund prior to such non-affiliated Trustee's retirement, has at least 10 years of service (including years of service prior to adoption of the retirement plan) for the Fund and retires at or after attaining the age of 60, is eligible to receive a retirement benefit each year for ten years following such Trustee's retirement from the Fund. Non-affiliated Trustees retiring prior to the age of 60 or with fewer than 10 years but more than 5 years of service may receive reduced retirement benefits from the Fund. Each Trustee has served as a member of each Fund's Board of Trustees since the year of such Trustee's appointment or election as set forth in the "Information Regarding Incumbent Trustees and Nominees for Election as Trustee" section of this Proxy Statement. Additional information regarding compensation and benefits for incumbent Trustees is set forth below. As indicated in the notes accompanying the table, the amounts relate to either the Fund's most recently completed fiscal year ended 13 July 31, 2005, the Fund Complex's most recently completed calendar year ended December 31, 2005 or the date of this Proxy Statement.

(2) The amounts shown in this column are the aggregate compensation payable by the Fund for its fiscal year ended in July 31, 2005 before deferral by the Trustees under the deferred compensation plan. The following Trustees deferred compensation from the Fund during the fiscal year ended July 31, 2005: Mr. Dammeyer, $17,814; Mr. Sonnenschein, $17,814; and Mr. Whalen, $17,814. The cumulative deferred compensation (including interest) accrued with respect to each Trustee, including former Trustees, from the Fund as of the Fund's fiscal year ended July 31, 2005 is as follows: Mr. Dammeyer, $119,366; Mr. Kerr, $10,423; Mr. Sonnenschein, $123,220; and Mr. Whalen, $134,492. (3) The amounts shown in this column represent the sum of the estimated pension or retirement benefit accruals expected to be accrued by the operating funds in the Fund Complex for their respective fiscal years ended in 2005. The retirement plan is described above the compensation table. (4) For each Trustee, this is the sum of the estimated maximum annual benefits payable by the current (i.e., as of the date of this Proxy Statement) operating funds in the Fund Complex for each year of the 10-year period commencing in the year of such Trustee's anticipated retirement. The retirement plan is described above the compensation table. (5) The amounts shown in this column are accumulated from the aggregate compensation of the operating investment companies in the Fund Complex for the calendar year ended December 31, 2005 before deferral by the Trustees under the deferred compensation plan. Because the funds in the Fund Complex have different fiscal year ends, the amounts shown in this column are presented on a calendar year basis. BOARD COMMITTEES AND MEETINGS The Fund's Board of Trustees has one standing committee (an audit and governance committee). This committee is comprised solely of "Independent Trustees", which is defined for purposes herein as trustees who: (1) are not "interested persons" of the Fund as defined by the 1940 Act and (2) are 14 "independent" of the Fund as defined by the New York Stock Exchange, American Stock Exchange and Chicago Stock Exchange listing standards. The Board's audit committee consists of Messrs. Arch, Dammeyer, Kerr and Sonnenschein. In addition to being Independent Trustees as defined above, each of these Trustees also meets the additional independence requirements for audit committee members as defined by the New York Stock Exchange, American Stock Exchange and Chicago Stock Exchange listing standards. The audit committee makes recommendations to the Board of Trustees concerning the selection of the Fund's independent public auditors, reviews with such auditors the scope and results of the Fund's annual audit and considers any comments which the auditors may have regarding the Fund's financial statements, books of account or internal controls. The Board of Trustees has adopted a formal written charter for the audit committee which sets forth the audit committee's responsibilities. The audit committee has reviewed and discussed the financial statements of the Fund with management as well as with the independent auditors of the Fund, and discussed with the independent auditors the matters required to be discussed under the Statement of Auditing Standards No. 61. The audit committee has received the written disclosures and the letter from the independent auditors required under Independence Standards Board Standard No. 1 and has discussed with the independent auditors their independence. Based on this review, the audit committee recommended to the Board of Trustees of the Fund that the Fund's audited financial statements be included in the Fund's annual report to shareholders for the most recent fiscal year for filing with the Securities and Exchange Commission ("SEC"). The Fund's audit committee financial expert is Mr. Dammeyer. In accordance with proxy rules promulgated by the SEC, a fund's audit committee charter is required to be filed at least once every three years as an exhibit to a fund's proxy statement. The audit committee charter for the Fund was attached as Annex A to the Fund's 2004 Proxy Statement. The Board's governance committee consists of Messrs. Arch, Dammeyer, Kerr and Sonnenschein. In addition to being Independent Trustees as defined above, each of these Trustees also meets the additional independence requirements for nominating committee members as defined by the New York Stock Exchange, American Stock Exchange and Chicago Stock Exchange listing standards. The governance committee identifies individuals qualified to serve as Independent Trustees on the Board and on committees of the Board, advises the Board with respect to Board composition, procedures and committees, develops and recommends to the Board a set of corporate governance principles applicable to the respective Fund, monitors corporate governance matters and makes recommendations to the Board, and acts as the administrative committee with respect to Board policies and procedures, committee policies and procedures and codes of ethics. The Independent Trustees of the Fund select and nominate any 15 other nominee Independent Trustees for the respective Fund. While the Independent Trustees of the Fund expect to be able to continue to identify from their own resources an ample number of qualified candidates for the Board of Trustees as they deem appropriate, they will consider nominations from shareholders to the Board. Nominations from shareholders should be in writing and sent to the Independent Trustees as described below. In accordance with proxy rules promulgated by the SEC, a fund's nominating committee charter is required to be filed at least once every three years as an exhibit to a fund's proxy statement. The governance committee charter for the Fund, which includes the Fund's nominating policies, was attached as Annex B to the Fund's 2004 Proxy Statement. During the fiscal year ended July 31, 2005, the Board of Trustees of the Fund held 16 meetings. During the Fund's last fiscal year, the audit and governance committee held 4 meetings. During the last fiscal year, each of the Trustees of the Fund during the period such Trustee served as a Trustee attended at least 75% of the meetings of the Board of Trustees and all committee meetings thereof of which such Trustee was a member. If the new nominees are elected to the Board, it is anticipated that the Board will change its committee structure to better align the Board committees of the Fund with the Board committees of the other Van Kampen funds that are overseen by the same Trustees. Accordingly, the Board is expected to split the current audit and governance committee into two separate standing committees of the Board. The membership of the audit committee would be changed to include Messrs. Choate, Dammeyer and Kennedy. The membership of the governance committee would be changed to include Messrs. Arch, Kerr and Nelson. A new committee, entitled the brokerage and services committee, would be created and its members would include Mesdames Heagy and Woolsey and Mr. Sonnenschein. The brokerage and services committee would review the Fund's allocation of brokerage transactions, if any, and review transfer agency and shareholder servicing arrangements. If structured in this way, all committees of the Fund would be comprised of "Independent Trustees" as defined above. SHAREHOLDER COMMUNICATIONS Shareholders may send communications to the Fund's Board of Trustees. Shareholders should send communications intended for the Board by addressing the communication directly to the Board (or individual Board members) and/or otherwise clearly indicating in the salutation that the communication is for the Board (or individual Board members) and by sending the communication to either the Fund's office or directly to such Board member(s) at the address specified for such Trustee above. Other shareholder communications received by the Fund not directly addressed and sent to the Board will be reviewed and generally responded to by management, and will be forwarded to the Board only at management's discretion based on the matters contained therein. 16 SHAREHOLDER APPROVAL With respect to this proposal, the holders of Common Shares and Preferred Shares, voting as a separate class, will vote on the respective nominees designated to be elected by such class of shares. The affirmative vote of a plurality of the Common Shares of each Fund present at the Meeting in person or by proxy is required to elect each nominee for Trustee designated to be elected by the Common Shares and the affirmative vote of a plurality of the Preferred Shares of the Fund present at the Meeting in person or by proxy is required to elect each nominee for Trustee designated to be elected by the Preferred Shares. THE BOARD OF TRUSTEES RECOMMENDS A VOTE "FOR ALL" OF THE NOMINEES. 17 -------------------------------------------------------------------------------- OTHER INFORMATION -------------------------------------------------------------------------------- EXECUTIVE OFFICERS OF THE FUND The following information relates to the executive officers of the Fund.

As of May 12, 2006, the following Trustees beneficially owned Common Shares of the Fund, in the amounts shown: Mr. Sonnenschein, 793 Common Shares; and Mr. Whalen, 500 Common Shares. As of May 12, 2006, the Trustees and executive officers of the Fund individually and as a group owned less than 1% of the outstanding Common Shares of the Fund. SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE Section 30(f) of the 1940 Act and Section 16(a) of the Securities Exchange Act of 1934, as amended, require the Fund's Trustees, officers, Adviser, affiliated 21 persons of the Adviser and persons who own more than 10% of a registered class of the Fund's equity securities to file forms with the SEC and the New York Stock Exchange reporting their affiliation with the Fund and reports of ownership and changes in ownership of shares of the Fund. These persons and entities are required by SEC regulation to furnish the Fund with copies of all such forms they file. Based on a review of these forms furnished to the Fund, the Fund believes that during its last fiscal year, its Trustees, officers, the Adviser and affiliated persons of the Adviser complied with the applicable filing requirements. INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM The Board of Trustees of the Fund, including a majority of the Trustees who are not "interested persons" of the Fund (as defined by the 1940 Act), has selected Deloitte & Touche LLP ("D&T") as the independent registered public accounting firm to examine the financial statements for the current fiscal year of the Fund. The selection of D&T for the current fiscal year was recommended and approved by the Fund's audit committee and approved by the Fund's Board. The Fund knows of no direct or indirect financial interest of D&T in the Fund. AUDIT AND OTHER FEES The Fund and certain "covered entities" were billed the following amounts by D&T during the Fund's most recent two fiscal years. FISCAL YEAR ENDED JULY 31, 2005 NON-AUDIT FEES -------------------------------------- AUDIT AUDIT- ALL TOTAL ENTITY FEES RELATED TAX OTHER NON-AUDIT TOTAL ------ ----- ------- --- ----- --------- ----- Fund................. $73,550 $ 10,000(2) $2,400(4) $0 $ 12,400 $ 85,950 Covered Entities(1)........

N/A $230,000(3) $ 0 $0 $230,000 $230,000 --------------- (1) Covered Entities include the Adviser and any entity controlling, controlled by or under common control with the Adviser that provides ongoing services to the Fund. 22 (2) Audit-Related Fees represent agreed upon procedures related to the maintenance of preferred shares of the Fund. (3) Audit-Related Fees represent assurance and related services provided that are reasonably related to the performance of the audit of the financial statements of the Covered Entities and funds advised by the Adviser or its affiliates, specifically attestation services provided in connection with a SAS 70 Report. (4) Tax Fees represent tax advice and compliance services provided in connection with the review of the Fund's tax return. (5) Audit-Related Fees represent agreed upon procedures, and letters provided to underwriters related to the offering, issuance and maintenance of preferred shares by the Fund. The audit committee of the Board has considered whether the provision of non- audit services performed by D&T to the Fund and "covered entities" is compatible with maintaining D&T's independence in performing audit services. The audit committee also is required to pre-approve services to "covered entities" to the extent that the services are determined to have a direct impact on the operations or financial reporting of the Fund. 100% of such services were pre-approved by the audit committee pursuant to the audit committee's pre-approval policies and procedures. The Board's pre-approval policies and procedures are included as part of the Board's audit committee charter, which was filed as Annex A to the Fund's 2004 Proxy Statement. Representatives of D&T will attend the Meeting, will have the opportunity to make a statement if they desire to do so and will be available to answer appropriate questions. EXPENSES The Fund will bear the expense of preparing, printing and mailing the enclosed form of proxy, the accompanying Notice and this Proxy Statement and all other costs, in connection with the solicitation of proxies. The Fund will also reimburse banks, brokers and others for their reasonable expenses in forwarding proxy solicitation material to the beneficial owners of the shares of the Fund. In order to obtain the necessary quorum at the Meeting, additional solicitation may be made by mail, telephone, telegraph, facsimile or personal interview by representatives of the Fund, the Adviser or Van Kampen, by the transfer agents of the Fund, by dealers or their representatives or by Computershare Fund Services, a solicitation firm that may be engaged to assist in proxy solicitation at an estimated cost of approximately $2,000. 23 SHAREHOLDER PROPOSALS To be considered for presentation at a shareholders' meeting, rules promulgated by the SEC generally require that, among other things, a shareholder's proposal must be received at the offices of the Fund a reasonable time before a solicitation is made. Shareholder proposals intended to be presented at the year 2007 Annual Meeting of Shareholders for the Fund pursuant to Rule 14a-8 under the Exchange Act of 1934, as amended (the "Exchange Act"), must be received by the Fund at the Fund's principal executive offices by January 24, 2007. In order for proposals made outside of Rule 14a-8 under the Exchange Act to be considered "timely" within the meaning of Rule 14a-4(c) under the Exchange Act, such proposals must be received by the Fund at the Fund's principal executive offices not later than April 10, 2007. Timely submission of a proposal does not necessarily mean that such proposal will be included. Any shareholder who wishes to submit a proposal for consideration at a meeting of the Fund should send such proposal to the Fund at 1 Parkview Plaza, PO Box 5555, Oakbrook Terrace, Illinois 60181-5555. GENERAL Management of the Fund does not intend to present and does not have reason to believe that others will present any other items of business at the Meeting. However, if other matters are properly presented to the Meeting for a vote, the proxies will be voted upon such matters in accordance with the judgment of the persons acting under the proxies. A list of shareholders of the Fund entitled to be present and vote at the Meeting will be available at the offices of the Fund, 1 Parkview Plaza, Oakbrook Terrace, Illinois 60181-5555, for inspection by any shareholder during regular business hours for ten days prior to the date of the Meeting.
