SEC 1913 (04-05) FOR SHAREHOLDERS OF JANUS RESEARCH FUND (THE "FUND") (JANUS LOGO) Dear Shareholder: Your Fund's Board of Trustees requests your vote on a proposal to change your Fund's benchmark index to the Morgan Stanley Capital International ("MSCI") World Growth Index instead of the Russell 1000(R) Index. Your vote is important since the benchmark index is used for purposes of calculating the performance-based investment advisory fee the Fund pays to Janus Capital Management LLC. This proposal will be presented to shareholders at a Special Meeting of Shareholders to be held December 14, 2006. We encourage you to read the Questions and Answers section at the beginning of the enclosed Proxy Statement as well as the entire Proxy Statement, which describes the proposal. Janus Research Fund (the "Fund") was launched in February 2005 with the flexibility to invest in the highest conviction ideas of the Janus equity research team that manages the Fund, regardless of where geographically those opportunities are found. Janus Capital's rationale for changing the benchmark index is based upon the fact that as the Fund pursued its "go-anywhere" strategy investing in domestic and international securities, the research team found increased opportunities for compelling investments in international markets. In recognition of the increasingly global character of the Fund's portfolio, Janus Capital proposed, and your Fund's Board of Trustees approved, (1) changing the name of the Fund to "Janus Global Research Fund" and (2) adopting an additional investment strategy so that the Fund will normally invest at least 40% of its net assets in securities of issuers from different countries located throughout the world, excluding the United States. As a result of these changes, the Fund's current benchmark index, the Russell 1000(R) Index, which measures the performance of only U.S. equities, may no longer be the most appropriate benchmark index for evaluating the Fund's performance. The proposed benchmark index, the MSCI World Growth Index, which measures the performance of growth stocks of developed countries around the world, is considered by Janus Capital and the Fund's Board of Trustees to be a more appropriate benchmark index for evaluating the Fund's performance, as it better reflects the Fund's investment policies and the research team's long-term expectations of finding investment opportunities throughout the world. The Fund's name will change to "Janus Global Research Fund" on or about December 31, 2006. The Fund's additional investment strategy will also become effective on or about December 31, 2006. YOUR FUND'S BOARD OF TRUSTEES HAS APPROVED THE BENCHMARK INDEX CHANGE AND BELIEVES THIS CHANGE IS IN THE BEST INTEREST OF SHAREHOLDERS. THE FUND'S BOARD OF TRUSTEES RECOMMENDS THAT SHAREHOLDERS VOTE "FOR" THE PROPOSAL. You can vote in one of four ways: - BY MAIL with the enclosed proxy card; - BY INTERNET through the website listed in the proxy voting instructions; - BY TELEPHONE using the toll-free number listed in the proxy voting instructions; or - IN PERSON at the Special Meeting of Shareholders on December 14, 2006.

THE FUND PROVIDES ANNUAL AND SEMIANNUAL REPORTS TO ITS SHAREHOLDERS THAT HIGHLIGHT RELEVANT INFORMATION, INCLUDING INVESTMENT RESULTS AND A REVIEW OF PORTFOLIO CHANGES. ADDITIONAL COPIES OF THE FUND'S MOST RECENT ANNUAL REPORT AND ANY MORE RECENT SEMIANNUAL REPORT ARE AVAILABLE, WITHOUT CHARGE, BY CALLING A JANUS REPRESENTATIVE AT 1-800-525-3713, VIA THE INTERNET AT WWW.JANUS.COM, OR BY SENDING A WRITTEN REQUEST TO THE SECRETARY OF THE TRUST AT 151 DETROIT STREET, DENVER, COLORADO 80206. QUESTIONS AND ANSWERS WHAT IS BEING PROPOSED? The proposal seeks approval of an amendment to the Fund's investment advisory agreement, which changes the Fund's benchmark index from the Russell 1000(R) Index to the Morgan Stanley Capital International ("MSCI") World Growth Index. The benchmark index is used to calculate any adjustment upward or downward to the investment advisory fee paid to Janus Capital Management LLC ("Janus Capital") by the Fund, based upon the investment performance of the Fund relative to the performance of the benchmark index. Janus Capital is the Fund's investment adviser pursuant to an Investment Advisory Agreement dated December 2, 2004, as amended January 1, 2006 and June 14, 2006, and which was approved by shareholders on December 29, 2005 (the "Current Investment Advisory Agreement"). The Current Investment Advisory Agreement contains a performance-based investment advisory fee structure. The investment advisory fee the Fund pays to Janus Capital decreases when the Fund is not performing well relative to its benchmark index and increases during periods when the Fund outperforms its benchmark index. WHAT IS THE RECOMMENDATION OF THE BOARD OF TRUSTEES? The Board of Trustees recommends that shareholders vote FOR the proposal. WHY IS JANUS CAPITAL PROPOSING TO CHANGE THE FUND'S BENCHMARK INDEX? Janus Capital's equity research analysts select investments for the Fund, which represent their high conviction investment ideas in all market capitalizations, styles, and geographies. The Fund was launched in February 2005 with the broad flexibility for the research team to invest in companies of any size and located anywhere in the world. While the Fund has always had the ability to have foreign exposure and was expected to have some foreign exposure as market conditions permitted, the "best ideas" strategies of the Fund combined with the global nature of Janus Capital's research have resulted in a higher emphasis on foreign stocks and a global strategy. Using the Fund's current investment objective and strategies, the research team has found, and continues to find compelling investment opportunities for the Fund outside of the United States. Over the long-term, the Fund expects to continue and may increase its foreign exposure. As a result, the Fund's name will change to "Janus Global Research Fund" effective on or about December 31, 2006, and the Fund's investment polices will be revised so that the Fund will normally invest at least 40% of its net assets in securities of issuers from different countries located throughout the world, excluding the United States. The current benchmark index for evaluating the Fund's performance, the Russell 1000(R) Index, measures the performance of the 1,000 largest companies in the Russell 3000(R) Index, and is made up entirely of U.S. companies. The proposed benchmark, 2 the MSCI World Growth Index, measures the performance of growth stocks of developed countries around the world, and, as of [date], U.S. companies constituted [ %] of the index. Given the Fund's evolution to a more global strategy, Janus Capital believes the MSCI World Growth Index is a more appropriate benchmark for evaluating the Fund's performance and better reflects the research team's long-term expectations of locating investment opportunities throughout the world. WILL THE CHANGE IN THE BENCHMARK INDEX RESULT IN A CHANGE TO THE INVESTMENT OBJECTIVE OR STRATEGIES OF THE FUND? The investment objective will remain the same, which is to seek long-term growth of capital. The Fund expects to maintain its current investment parameters of investing in companies of any size and located anywhere in the world, from larger, well-established companies to smaller, emerging growth companies. Pursuant to the Fund's additional investment strategy, the Fund will normally invest at least 40% of its net assets in securities of issuers from different countries located throughout the world, excluding the United States. The risks of investment in foreign securities, including those in emerging markets, are described in the Fund's prospectus. WHAT EFFECT WILL THE BENCHMARK INDEX CHANGE HAVE UPON THE INVESTMENT ADVISORY FEE RATE THE FUND PAYS TO JANUS CAPITAL? The benchmark index change will not alter the base fee component of the investment advisory fee, which is an annualized rate of 0.64% of the average daily closing net asset value of the Fund. Whether the change in the benchmark index to the MSCI World Growth Index results in an increase or decrease in the performance fee component of the advisory fees that otherwise would have been paid by the Fund depends on whether the Fund's future performance compares more favorably with the MSCI World Growth Index or the Russell 1000(R) Index. As discussed in the Proxy Statement, based on a pro forma analysis of the Fund's past performance over comparable periods under identical assumptions, Janus Capital would have been paid less if the performance fee component was calculated using the MSCI World Growth Index. It is not possible to predict the effect of the performance adjustment on future overall compensation paid by the Fund to Janus Capital since any adjustment will depend on the cumulative performance of the Fund relative to the approved Fund benchmark index, as well as future changes to the size of the Fund over the specified period of time. WHAT WILL HAPPEN IF SHAREHOLDERS DO NOT APPROVE THE PROPOSAL? The Russell 1000(R) Index would remain the Fund's benchmark index for purposes of calculating the Fund's performance adjustment to the investment advisory fee paid to Janus Capital by the Fund. 3 HOW DO I VOTE MY SHARES? You can vote in any one of four ways: - By mail, by sending the enclosed proxy card (signed and dated) in the enclosed envelope; - Through the Internet by going to the website listed on your proxy card; - By telephone using the toll-free number listed on your proxy card; or - In person, by attending the Special Meeting of Shareholders on December 14, 2006 (or any adjournment or postponement thereof). Whichever method you choose, please take the time to read the full text of the Proxy Statement before you vote. IF I SEND MY PROXY IN NOW AS REQUESTED, CAN I CHANGE MY VOTE LATER? Yes. You may revoke your proxy vote at any time before it is voted at the Meeting by: (i) delivering a written revocation to the Secretary of the Fund at 151 Detroit Street, Denver, Colorado 80206; (ii) submitting a subsequently executed proxy vote; or (iii) attending the Meeting and voting in person. Even if you plan to attend the Meeting, we ask that you return the enclosed proxy. This will help us ensure that an adequate number of shares are present at the Meeting for consideration of the proposal. WHAT IS THE REQUIRED VOTE TO APPROVE THE PROPOSAL? Approval of the proposal will require the affirmative vote of a "majority of the outstanding voting securities" of the Fund within the meaning of the Investment Company Act of 1940, as amended (the "1940 Act"). This means the affirmative of the lesser of (i) 67% or more of the shares of the Fund present at the Meeting if the holders of more than 50% of the outstanding shares are present or represented by proxy, or (ii) more than 50% of the outstanding shares (a "1940 Act Majority"). WHOM SHOULD I CALL FOR ADDITIONAL INFORMATION ABOUT THIS PROXY STATEMENT? Please call D.F. King & Co., Inc. your Fund's proxy solicitor, at [ ]. 4 PROPOSAL APPROVE AN AMENDMENT TO THE FUND'S INVESTMENT ADVISORY AGREEMENT, WHICH CHANGES THE FUND'S BENCHMARK INDEX FOR PURPOSES OF CALCULATING THE PERFORMANCE-BASED INVESTMENT ADVISORY FEE. INTRODUCTION On September 6, 2006, the Fund's Board of Trustees, including the Trustees who are not "interested persons" of the Fund or Janus Capital, approved an amendment to the Current Investment Advisory Agreement between the Trust, on behalf of the Fund, and Janus Capital, ("Proposed Advisory Agreement") and authorized the submission of the Proposed Advisory Agreement to the Fund's shareholders for approval. The Proposed Advisory Agreement changes the performance benchmark index used to determine one component of the investment advisory fee that Janus Capital receives from the Fund. The investment advisory fee paid by the Fund currently is adjusted downward or upward based upon the Fund's performance relative to the Russell 1000(R) Index (the "Current Index"). Under the proposal, the fee would instead be adjusted based upon the Fund's performance relative to the MSCI World Growth Index (the "Proposed Index"). This means that if the Proposal is approved, the Fund's benchmark index will change from an index designed as a measure of performance of U.S. companies to an index designed to be a measure of growth stocks of companies located throughout the world. The Proposal is a result of how the Fund has evolved since its inception in February 2005. Janus Capital's equity research analysts select investments for the Fund, which represent their high conviction investment ideas in all market capitalizations, styles, and geographies. The Fund permits broad flexibility for the research team to invest in companies of any size, and which may be located anywhere in the world. While the Fund was initially expected to have some foreign exposure as permitted under its investment strategies, the "best ideas" strategies of the Fund, combined with the global nature of Janus Capital's research, have resulted in a higher emphasis on foreign stocks and a global strategy. Using the Fund's current investment objective and strategies, the research team has found, and continues to find compelling investment opportunities outside of the United States. In recognition of the increasingly global character of the Fund's portfolio, Janus Capital proposed, and the Fund's Board of Trustees approved, (1) changing the name of the Fund to "Janus Global Research Fund" and (2) adopting an additional investment strategy so that the Fund will normally invest at least 40% of its net assets in securities of issuers from different countries located throughout the world, excluding the United States. Accordingly, Janus Capital believes the proposed change of the benchmark index to the MSCI World Growth Index, which measures the performance of growth stocks of developed countries around the world, is a more appropriate benchmark index to evaluate the Fund's performance and better reflects the research team's long-term expectations of locating investment opportunities throughout the world. 5 The Fund's investment objective to seek long-term growth of capital remains the same. The strategy to invest in companies of any size and located anywhere in the world, from larger, well-established companies to smaller, emerging growth companies remains. The change of the Fund's name to "Janus Global Research Fund" and additional 40% investment strategy will become effective on or about December 31, 2006. The risks of investment in foreign securities, including those in emerging markets, are described in the Fund's prospectus. If approved, the Proposed Advisory Agreement will take effect on January 1, 2007 or as soon as practicable after shareholder approval is obtained. The Proposed Advisory Agreement will remain in effect through January 1, 2008, and thereafter, only as long as its continuance is approved at least annually by (i) the vote, cast in person at a meeting called for the purpose, of a majority of the Independent Trustees and (ii) the vote of either a majority of the Trustees or a majority of the outstanding shares of the Fund. If the Proposed Advisory Agreement is not approved, the Current Investment Advisory Agreement will continue in effect through January 1, 2007, and thereafter only as long as its continuance is approved at least annually as described above. Except for changes to reflect the name change to "Janus Global Research Fund" which will become effective on or about December 31, 2006 and the proposed change to the performance benchmark index, the Proposed Advisory Agreement is substantially similar to the Current Investment Advisory Agreement. A copy of the Proposed Advisory Agreement is included as Exhibit A. JANUS CAPITAL AS INVESTMENT ADVISER Janus Capital Management LLC, 151 Detroit Street, Denver, Colorado 80206- 4805, is the Fund's investment adviser pursuant to the Current Investment Advisory Agreement. Janus Capital is a direct subsidiary of Janus Capital Group Inc. ("JCGI"), a publicly-traded company with principal operations in financial asset management businesses. JCGI owns approximately 95% of Janus Capital, with the remaining 5% held by Janus Management Holdings Corporation. The principal executive officers and directors of Janus Capital, located at 151 Detroit Street, Denver, Colorado 80206, and their principal occupations are included in [Exhibit B] to this Proxy Statement. Certain employees of Janus Capital and/or its affiliates serve as officers of the Trust. Certain officers and interested Trustees of the Trust are shareholders of JCGI. Janus Capital (together with its predecessors) has served as an investment adviser since 1970. As of [September 1, 2006], the Janus funds that Janus Capital advises consisted of [ ] portfolios offering a broad range of investment objectives. Janus Capital also serves as subadviser for a number of private-label mutual funds and provides separate account advisory services for institutional accounts. As of [ , 2006], Janus Capital had approximately [$ billion] in assets under management. Janus Capital currently serves as an investment adviser to other funds that have similar investment objectives as the Fund, as described in detail in [Exhibit ] to this Proxy Statement. 6 DESCRIPTION OF THE CURRENT INVESTMENT ADVISORY AGREEMENT Under the Current Investment Advisory Agreement, Janus Capital provides the Fund with continuing investment management services. Janus Capital is responsible for the day-to-day management of the Fund and provides continuous investment advice regarding the purchase and sale of securities held by the Fund, subject to the Trust's Amended and Restated Agreement and Declaration of Trust, its Amended and Restated Bylaws, the investment objective, the policies and restrictions set forth in the Fund's registration statement, the provisions of the 1940 Act and the Internal Revenue Code of 1986, as amended, and such other policies and instructions as the Trustees may determine from time to time. Janus Capital provides office space for the Fund and pays the salaries, fees and expenses of all Fund officers (splitting a portion of compensation and expenses of the Fund's Chief Compliance Officer with the Fund) and any Trustee who is considered an interested person of Janus Capital. Janus Capital provides certain administrative, compliance, accounting, and other services and is responsible for the other business affairs of the Fund. The Fund pays all expenses incident to its organization, operations, and business not specifically assumed by Janus Capital, including custodian and transfer agency fees and expenses, brokerage commissions and dealer spreads, and other expenses in connection with the execution of portfolio transactions, legal and accounting expenses, interest, taxes, a portion of trade association or other investment company organization dues and expenses, registration fees, expenses of shareholders' meetings, reports to shareholders, fees and expenses of Independent Trustees, and other costs of complying with applicable laws regulating the sale of Fund shares. Information concerning services provided by Janus Distributors LLC ("Janus Distributors"), the Fund's distributor, and Janus Services LLC ("Janus Services"), the Fund's transfer agent, each a wholly-owned subsidiary of Janus Capital, and a description of any fees paid by the Fund to Janus Distributors and Janus Services, is provided on page [ ] of this Proxy Statement. The Current Investment Advisory Agreement for Janus Research Fund was initially approved by the Trustees, including all of the Independent Trustees, on December 2, 2004 and subsequently amended on January 1, 2006 and June 14, 2006. The Fund's Current Investment Advisory Agreement continues in effect until January 1, 2007 and thereafter from year to year as long as such continuance is approved at least annually by a majority of the Independent Trustees, and by either a majority of the outstanding voting securities of the Fund or the Trustees of the Fund. The Current Investment Advisory Agreement: (i) may be terminated, without the payment of any penalty, by Janus Capital, the Trustees of the Trust, or the shareholders of the Fund acting by vote of at least a majority of its outstanding voting securities on 60 days advance written notice; (ii) terminates automatically in the event of its assignment; and (iii) generally, may not be amended without the approval by vote of a majority of the Trustees of the Fund, including a majority of the Independent Trustees 7 and, to the extent required by the 1940 Act, the vote of a majority of the outstanding voting securities of the Fund. The Current Investment Advisory Agreement was last submitted to a vote of shareholders on December 29, 2005 for purposes of approving a performance-based investment advisory fee structure and to make certain conforming changes to clarify Janus Capital's investment discretion in managing the Fund. WHAT IS THE SAME BETWEEN THE CURRENT INVESTMENT ADVISORY AGREEMENT AND THE PROPOSED ADVISORY AGREEMENT? The Current Investment Advisory Agreement and Proposed Advisory Agreement are substantially similar. Under both the Current Investment Advisory Agreement and the Proposed Advisory Agreement, the Fund pays Janus Capital an investment advisory fee that consists of two components: (i) a base management fee at the annual rate of 0.64% of the Fund's average daily net assets during the previous month ("Base Fee"), plus or minus (ii) a performance-fee adjustment ("Performance Adjustment") calculated by applying a variable rate of up to 0.15% (positive or negative) to the Fund's average daily net assets during the applicable performance measurement period. The performance measurement period generally will be the previous 36 months, although no Performance Adjustment is made until the Current Investment Advisory Agreement has been in effect for at least 12 months. The Current Investment Advisory Agreement became effective on January 1, 2006. The first calculation of a Performance Adjustment will occur in January 2007 for the prior 12-month performance measurement period. After January 2007 and until month 36 (or January 2009) that the Current Investment Advisory Agreement has been in effect, the performance measurement period will be equal to the time that has elapsed since the Current Investment Advisory Agreement took effect. The Base Fee is calculated and accrued daily. The Performance Adjustment is calculated monthly in arrears and is accrued evenly each day throughout the month. The investment advisory fee is paid monthly in arrears. Under both the Current Investment Advisory Agreement and the Proposed Advisory Agreement, the Performance Adjustment may result in an increase or decrease in the investment advisory fee paid by the Fund, depending upon the total return performance of the Fund after expenses relative to the performance of its benchmark index over the performance measurement period. No Performance Adjustment will be applied unless the difference between the Fund's total return performance and the investment record of the Fund's benchmark index is 0.50% or greater (positive or negative) during the applicable performance measurement period. Because the Performance Adjustment is tied to the Fund's performance relative to its benchmark index (and not its absolute performance), the Performance Adjustment could increase Janus Capital's fee even if the Fund's total return has been negative during the performance measurement period and could decrease Janus Capital's fee even if the Fund's total return has been positive during the performance measurement period. For purposes of computing the Base Fee and the Performance Adjustment, net assets are averaged over different periods (average daily net assets during the previous month for the Base Fee, versus average daily net assets during the performance measurement 8 period for the Performance Adjustment). Performance of the Fund is calculated net of expenses whereas the Fund's benchmark index does not have any fees or expenses. Reinvestment of dividends and distributions are included in calculating the performance of both the Fund and the Fund's benchmark index. Should the Trustees subsequently decide to divide shares of the Fund into two or more separate classes, the oldest class of shares will be used for purposes of determining the Performance Adjustment. After Janus Capital determines whether the Fund's performance was above or below its benchmark index by comparing the investment performance of the Fund's oldest share class against the investment record of the Fund's benchmark index, Janus Capital will apply the same Performance Adjustment (positive or negative) across each other class of shares of the Fund. WHAT ARE THE SIGNIFICANT DIFFERENCES BETWEEN THE CURRENT INVESTMENT ADVISORY AGREEMENT AND THE PROPOSED ADVISORY AGREEMENT? Other than the change to reflect the name change to "Janus Global Research Fund," which automatically becomes effective on or about December 31, 2006, and the date of effectiveness, the primary difference between the Current Investment Advisory Agreement and the Proposed Advisory Agreement is the benchmark index used for purposes of measuring the Fund's performance and calculating the Performance Adjustment to the investment advisory fee the Fund pays to Janus Capital. Pursuant to the Current Investment Advisory Agreement, the investment advisory fee is linked to the Fund's performance relative to the Russell 1000(R) Index. Under the Proposed Advisory Agreement, the investment advisory fee is linked to the Fund's performance relative to the MSCI World Growth Index. The Russell 1000(R) Index is a U.S. equity index that measures the performance of the largest 1,000 companies in the Russell 3000(R) Index. The MSCI World Growth Index measures the performance of growth stocks in developed countries throughout the world. The Trustees and shareholders of the Fund previously approved the Current Index as the Fund's benchmark index for purposes of evaluating the Fund's performance and calculating the investment advisory fee the Fund pays to Janus Capital. Shareholders are now being asked to approve a change in the benchmark index to the Proposed Index. If approved, the Proposed Advisory Agreement will become effective on January 1, 2007 or as soon as practicable after shareholder approval is obtained. For performance measurement periods prior to the effective date of the Proposed Advisory Agreement, the Current Index will be used for purposes of evaluating the Fund's performance and calculating the investment advisory fee. For performance measurement periods after that date, the Proposed Index will be used for that purpose, and will be implemented on a transitional basis described under "Implementation of the Change in the Benchmark Index" on page . If shareholders do not approve the Proposed Advisory Agreement, the Performance Adjustment will be implemented in January 2007 by measuring the Fund's performance relative to the Current Index in accordance with the terms of the Current Investment Advisory Agreement. 9 The Trustees may from time to time determine that another securities index is a more appropriate benchmark index for purposes of evaluating the Fund's performance. In that event, the Trustees will approve the substitution of a successor index for the Fund's benchmark index. However, the calculation of the Performance Adjustment for any portion of the performance measurement period prior to the adoption of the successor index will still be based upon the Fund's performance compared to its former benchmark index. Any change to the Fund's benchmark index for purposes of calculating the Performance Adjustment is subject to applicable law. It is currently the position of the staff ("Staff") of the Securities and Exchange Commission ("SEC") that any changes to the Fund's benchmark index will require shareholder approval. If there is a change in the Staff's position, the Trustees will notify the shareholders of such change in position at such time as the Trustees may determine that a change in the Fund's benchmark index is appropriate. INVESTMENT ADVISORY FEE PAID BY THE FUND TO JANUS CAPITAL As described above, the Performance Adjustment to the investment advisory fee will be implemented in January 2007. From the date of commencement of operations of the Fund (February 25, 2005) and until January 2007, the Fund pays Janus Capital a fee calculated at the annual rate of 0.64% of average daily net assets. Through March 1, 2007, Janus Capital has agreed by contract to waive its advisory fee payable by the Fund in an amount equal to the amount, if any, that the Fund's normal operating expenses in any fiscal year (including the investment advisory fee, but excluding any brokerage commissions, interest, taxes and extraordinary expenses) exceed 1.25% of the Fund's average daily net asset value. The following table shows the advisory fee paid by the Fund to Janus Capital before any waiver and the amount waived, if any, including any applicable advisory fee waiver, for the period February 25, 2005 (commencement of operations) to April 30, 2006. <Table> <Caption> ADVISORY FEE WAIVERS ------------ ------- $349,639 $70,326 </Table> IMPACT OF PROPOSED CHANGE TO THE BENCHMARK INDEX ON THE INVESTMENT ADVISORY FEE RATE Because the change in the Fund's benchmark index will be implemented prospectively, the future impact on the investment advisory fee rate paid by the Fund to Janus Capital will depend upon the Fund's future performance relative to the Proposed Index. In addition, the Fund has not completed a 12-month performance measurement period. However, the past performance of the Current Index, the Proposed Index, and the Fund can be used to show what the impact would have been on the investment advisory fee rate for the period from March 1, 2006 through July 31, 2006 if the advisory fee had been adjusted based upon the Fund's performance relative to the performance of either the Current Index or the Proposed Index during that 10 period. This hypothetical example assumes that each index was in place during the entire period and is based upon a performance measurement period beginning with the Fund's inception on February 25, 2005 (such that the first Performance Adjustment is based upon an initial 12-month performance measurement period). The following table shows: (i) the dollar amount of the pro forma advisory fee that would have been paid by the Fund, before and after all applicable waivers, for the period from March 1, 2006 through July 31, 2006 using the Current Index as the benchmark index; (ii) the dollar amount of the pro forma advisory fee that would have been paid by the Fund, before and after all applicable waivers, using the Proposed Index as the benchmark index; and (iii) the difference between the pro forma fees of each index, net of any waivers. Such difference is positive when the amount of the pro forma Proposed Index advisory fees would have been larger than the amount of the pro forma Current Index advisory fees and negative when the amount of the pro forma Proposed Index advisory fees would have been smaller than the amount of the pro forma Current Index advisory fees. <Table> <Caption> DIFFERENCE PRO FORMA ADVISORY FEE PRO FORMA ADVISORY FEE BETWEEN BASED UPON CURRENT INDEX BASED UPON PROPOSED INDEX PRO FORMA ----------------------------------------- ----------------------------------------- CURRENT AND ADVISORY FEE ADVISORY FEE ADVISORY FEE ADVISORY FEE PROPOSED BEFORE AFTER BEFORE AFTER INDEX WAIVERS ($) WAIVERS ($) WAIVERS ($) WAIVERS ($) WAIVERS ($) WAIVERS ($) ADVISORY FEES ------------ ----------- ------------ ------------ ----------- ------------ ------------- 520,250 70,326 449,924 501,326 70,326 431,000 (18,924) </Table> As reflected above in the table, the Fund would have paid $18,924 less to Janus Capital had the Proposed Index been in place during this hypothetical period, as compared to the Current Index during the same hypothetical period. Please keep in mind that under the terms of the Proposed Advisory Agreement, the change in the Fund's benchmark index will actually occur on a gradual basis over the 36-month period following shareholder approval of the Proposed Advisory Agreement. See "Implementation of the Change in the Benchmark Index" on page . COMPARISON OF PROPOSED AND CURRENT BENCHMARK INDICES If the proposal is approved by shareholders, the Fund will change its benchmark index from the Current Index, the Russell 1000(R) Index to the Proposed Index, the MSCI World Growth Index. The MSCI World Growth Index is a market capitalization weighted index composed of companies which exhibit growth attributes that are representative of the market structure of developed market countries in North America, Europe, and the Asia/Pacific Region. MSCI World Growth Index securities are classified as "growth" securities because of the high price to book valuation, relative to each MSCI country index. As of [date], U.S. companies constituted [ %] of the index. The Current Index, the Russell 1000(R) Index, measures the performance of the 1,000 largest companies in the Russell 3000(R) Index, and is made up entirely of U.S. companies. Janus Capital's research is global in nature and Janus Capital has 11 continued to find compelling investment opportunities for the Fund outside the United States. Janus Capital believes the Proposed Index better reflects the investment universe of the Fund, as the Proposed Index measures the performance of global growth stocks and is therefore believed to be more appropriate for evaluating the Fund's performance. The following chart shows how the returns of the Fund, the Current Index, and the Proposed Index have performed for the period of March 1, 2005 through August 31, 2006. (CHART) <Table> <Caption> PROPOSED INDEX- MSCI CURRENT INDEX - RUSSELL WORLD GROWTH INDEX (%) JANUS RESEARCH FUND (%) 1000(R) INDEX (%) ---------------------- ----------------------- ----------------------- 03/05 -1.91 -1.80 -1.82 04/05 -2.20 -2.44 -1.90 05/05 2.60 4.49 4.84 06/05 0.47 2.70 -0.37 07/05 4.14 5.35 4.89 08/05 0.89 1.75 -1.29 09/05 2.21 2.81 0.46 10/05 -2.13 -1.94 -0.97 11/05 3.24 4.14 4.31 12/05 2.18 2.50 -0.31 01/06 4.61 6.99 1.76 02/06 -1.02 -0.97 -0.16 03/06 2.49 2.93 1.48 04/06 2.31 1.50 -0.14 05/06 -3.85 -4.91 -3.39 06/06 -0.16 0.16 -0.39 07/06 -0.81 -1.15 -1.90 08/06 2.65 3.89 3.12 </Table> The following chart compares the calendar year performance of both the Current Index and the Proposed Index for the past five years. The chart shows that the two benchmarks have performed differently at times over this period. (CHART) <Table> <Caption> RUSSELL 1000(R) INDEX (%) MSCI WORLD GROWTH INDEX (%) ------------------------- --------------------------- 2001 -12.45 -19.38 2002 -21.65 -19.90 2003 29.89 28.08 2004 11.40 10.90 2005 6.27 9.41 </Table> 12 IMPLEMENTATION OF THE CHANGE IN THE BENCHMARK INDEX If the proposal is approved, the change in the Fund's benchmark index will be implemented on a prospective basis beginning January 1, 2007 or as soon as practicable following the date of shareholder approval. However, because the Performance Adjustment is based upon a rolling 36-month performance measurement period, comparisons to the Proposed Index will not be fully implemented for 36 months after the effective date of the Proposed Advisory Agreement. During this transition period, the Fund's returns will be compared to a 36-month blended index return that reflects the performance of the Current Index for the portion of the performance measurement period prior to adoption of the Proposed Index, and the performance of the Proposed Index for the remainder of the period. For periods following the first full 36-month performance measuring period, the performance measurement period would reflect one less month of the Current Index's performance. At the conclusion of the transition period, the performance of the Current Index would be eliminated from the Performance Adjustment calculation, and the calculation would include only the performance of the Proposed Index. HOW THE PERFORMANCE ADJUSTMENT WORKS If the average daily net assets of the Fund remain constant during a 36 month performance measurement period, current net assets will be the same as average net assets over the performance measurement period and the maximum Performance Adjustment will be equivalent to an annual rate of 0.15% of current net assets. When current net assets vary from net assets over the 36 month performance measurement period, the Performance Adjustment, as a percentage of current assets, may vary significantly, including at a rate more or less than 0.15%, depending upon whether the net assets of the Fund had been increasing or decreasing (and the amount of such increase or decrease) during the performance measurement period. Note that if net assets for the Fund were increasing during the performance measurement period, the total positive or negative Performance Adjustment, measured in dollars, would be greater than if the net assets of the Fund had not increased during the performance measurement period. The Fund is a newer fund that commenced operations on February 25, 2005 and, accordingly, the net assets of the Fund are expected to be increasing during the initial performance measurement periods, which is likely to result in a Performance Adjustment that will be a smaller percentage of the Fund's current assets than would be the case if the Fund's net assets remained constant during the entire performance measurement period. The net assets of the Fund as of August 31, 2006 were $ . The following hypothetical examples illustrate the application of the Performance Adjustment for the Fund. The examples assume that the average daily net assets of the Fund remain constant during a 36-month performance measurement period. The Performance Adjustment would be a smaller percentage of current assets if the net assets of the Fund were increasing during the performance measurement period, and a 13 greater percentage of current assets if the net assets of the Fund were decreasing during the performance measurement period. All numbers in the examples are rounded to the nearest hundredth percent. The monthly maximum positive or negative Performance Adjustment of 1/12th of 0.15% of average net assets during the prior 36 months occurs if the Fund outperforms or underperforms its benchmark index by 6.00% or more over the same period. The Performance Adjustment is made in even increments for every 0.50% difference in the total return performance of the Fund compared to the investment record of its benchmark index (applying either the Current Index or Proposed Index). EXAMPLE 1: FUND OUTPERFORMS ITS BENCHMARK BY 6% If the Fund has outperformed its benchmark index by 6% during the preceding 36 months, the Fund would calculate the investment advisory fee as follows: <Table> <Caption> MONTHLY MONTHLY PERFORMANCE TOTAL ADVISORY FEE RATE BASE FEE RATE ADJUSTMENT RATE FOR THAT MONTH --------------- ------------------- ----------------------- 1/12th of 0.64% 1/12th of 0.15% 1/12th of 0.79% </Table> EXAMPLE 2: FUND PERFORMANCE TRACKS ITS BENCHMARK If the Fund has tracked the performance of its benchmark index during the preceding 36 months, the Fund would calculate the investment advisory fee as follows: <Table> <Caption> MONTHLY MONTHLY PERFORMANCE TOTAL ADVISORY FEE RATE BASE FEE RATE ADJUSTMENT RATE FOR THAT MONTH --------------- ------------------- ----------------------- 1/12th of 0.64% 0.00 1/12th of 0.64% </Table> EXAMPLE 3: FUND UNDERPERFORMS ITS BENCHMARK BY 6% If the Fund has underperformed its benchmark index by 6% during the preceding 36 months, the Fund would calculate the investment advisory fee as follows: <Table> <Caption> MONTHLY MONTHLY PERFORMANCE TOTAL ADVISORY FEE RATE BASE FEE RATE ADJUSTMENT RATE FOR THAT MONTH --------------- ------------------- ----------------------- 1/12th of 0.64% 1/12th of -0.15% 1/12th of 0.49% </Table> Under extreme circumstances, involving underperformance and a rapidly shrinking asset base, the dollar amount of the Performance Adjustment could be more than the dollar amount of the Base Fee. In such circumstances, Janus Capital would reimburse the Fund. COMPARISON OF CURRENT AND PRO FORMA EXPENSES The following tables describe the shareholder fees and annual fund operating expenses that you may pay if you buy and hold shares of the Fund under the current fee structure and the pro forma fee structure applying both the Current Index and Proposed Index, without giving effect to any fee waivers. For purposes of pro forma calculations, it is assumed the Performance Adjustment would have been in effect and 14 calculated over the period February 25, 2005 to April 30, 2006 (from Fund inception through the end of the most recent semiannual period). The fees and expenses shown were determined based upon net assets as of April 30, 2006. For the February 25, 2005 to April 30, 2006 period, the Fund outperformed the Current Index and the April 30, 2006 daily net assets were higher than the trailing 14-month average daily net assets, resulting in the pro forma management fee shown in the Annual Fund Operating Expenses table below for the Fund. For the February 25, 2005 to April 30, 2006 period, the Fund outperformed the Proposed Index and the fiscal year end average daily net assets were higher than the trailing 14-month average daily net assets, resulting in the pro forma management fee shown in the Annual Fund Operating Expenses table below for the Fund. Shareholder fees are those paid directly from your investment and may include sales loads, redemption fees, or exchange fees. The Fund is a no-load investment, so you will generally not pay any fees when you buy or sell shares of the Fund. Annual fund operating expenses are paid out of the Fund's assets and include fees for portfolio management, maintenance of shareholder accounts, shareholder servicing, accounting, and other services. You do not pay these fees directly but, as the examples show, these costs are borne indirectly by all shareholders. The Trust, on behalf of the Fund, has entered into an expense waiver agreement with Janus Capital. In the expense waiver agreement, Janus Capital has agreed to reduce certain annual fund operating expenses to the extent that total operating expenses exceed a specific percentage of average daily net assets, subject to certain limitations described in the expense waiver agreement. Additional details with respect to the expense waiver agreement are described in the footnotes to the Annual Fund Operating Expenses table listed below. As a result of the expense waiver agreement, the actual Total Annual Operating Expenses may be less than the amount listed in the table. SHAREHOLDER FEES (PAID DIRECTLY FROM INVESTMENT)(1) (CURRENT AND PRO FORMA STRUCTURE) <Table> Maximum Sales Charge (Load) Imposed on Purchases........ None Redemption Fee (as a % of amount redeemed).............. None(2) </Table> --------------- (1) For shares purchased through an intermediary, your financial intermediary may charge a separate fee for purchases and sales of shares. (2) The Fund may charge a fee to cover the cost of sending a wire transfer for redemptions, and your bank may charge an additional fee to receive the wire. 15 ANNUAL FUND OPERATING EXPENSES (DEDUCTED FROM FUND ASSETS) <Table> <Caption> TOTAL ANNUAL MANAGEMENT OTHER OPERATING FEE EXPENSES EXPENSES(1) ---------- -------- ------------ Current as of 4/30/06 (unaudited)............... 0.64% 0.50% 1.14% Pro Forma Based upon Current Index..................... 0.66% 0.50% 1.16% Pro Forma Based upon Proposed Index............ 0.65% 0.50% 1.15% </Table> EXAMPLES: THE FOLLOWING EXAMPLES ARE BASED UPON EXPENSES WITHOUT WAIVERS AS SHOWN IN THE TABLES ABOVE. These examples are intended to help you compare the cost of investing in the Fund under both the current fee structure and the pro forma fee structure applying both the Current Index and the Proposed Index with the cost of investing in other mutual funds. The examples assume that you invest $10,000 in the Fund for the time periods indicated. Since no sales load applies, the results apply whether or not you redeem your shares at the end of the periods shown. The examples also assume that your investment has a 5% return each year and that the Fund's operating expenses without waivers remain the same. Although your actual costs may be higher or lower, based upon these assumptions, your costs would be: <Table> <Caption> 1 YEAR 3 YEARS 5 YEARS 10 YEARS ------ ------- ------- -------- Current....................... $116 $362 $628 $1,386 Pro Forma Based upon Current Index....................... $118 $368 $638 $1,409 Pro Forma Based upon Proposed Index....................... $117 $365 $633 $1,394 </Table> --------------- (1) Total Annual Operating Expenses do not reflect the application of a contractual expense waiver by Janus Capital. Janus Capital has contractually agreed to waive the Fund's total operating expenses (excluding items not normally considered operating expenses such as brokerage commissions, interest, taxes, and extraordinary expenses) to the extent such operating expenses exceed 1.25% of average daily net assets on the fiscal year ending date in which the agreement is in effect. Because a fee waiver will have a positive effect on a Fund's performance, a fee waiver that is in place during a given Performance Measurement Period when the Performance Adjustment applies may affect the Performance Adjustment in a way that is favorable to Janus Capital. It is possible that the cumulative dollar amount of additional compensation ultimately payable to Janus Capital for that period will, under some circumstances, exceed the cumulative dollar amount of fees waived by Janus Capital for that period. The current agreement will be in effect until [March 1, 2007], unless terminated, revised, or extended. Additionally, the current agreement does not contain any provisions allowing for the recoupment of any fees waived. Currently, the Fund is not operating above the 1.25% expense limit. 16 BOARD APPROVAL AND RECOMMENDATION The investment advisory agreement for the Fund provides that the Fund shall pay to Janus Capital a monthly base fee at the rate of 1/12 of 0.64% of the average daily net asset value of the Fund. In addition, commencing with the month of January 2007, the advisory fee is subject to a positive or negative adjustment based on the total return performance of the Fund relative to the performance of a specified benchmark index (the "Benchmark Index") over the applicable "Performance Period." The maximum positive or negative fee adjustment for any month is 1/12 of 0.15% of the monthly average net assets of the Fund. The original and current Benchmark Index for measuring the performance adjustment was the Russell 1000(R) Index (the "Current Index"), which measures the performance of U.S. equity securities. On September 6, 2006, the Board of Trustees, including all of the Independent Trustees, upon the recommendation of Janus Capital, voted unanimously to approve (1) changing the name of the Fund to "Janus Global Research Fund," effective December 31, 2006; (2) effective December 31, 2006, including as the Fund's investment policies that the Fund will normally invest at least 40% of its net assets in securities of issuers from different countries located throughout the world, excluding the United States; and (3) an amendment to the investment advisory agreement for the Fund to change the Benchmark Index from the Current Index to the Morgan Stanley Capital International World Growth Index (the "Proposed Index"). The Board recommended that the shareholders of the Fund approve that amendment at a meeting of shareholders called to be held on December 14, 2006. If the proposed amendment to the investment advisory agreement is approved by shareholders, the Current Index would continue to be used to measure Benchmark Index performance for any portion of a Performance Period through the end of the calendar month in which shareholder approval is obtained, and the Proposed Index would be used for any portion of a Performance Period commencing after that month. The Fund was launched in February 2005 with the flexibility to invest in the highest conviction ideas of the Janus Capital equity research team that manages the Fund, regardless of where geographically those opportunities are found. As the Fund pursued its "go-anywhere" strategy, the research team continued to find compelling investments for the Fund in both domestic and international markets. In view of the increased holdings of foreign securities in the Fund's portfolio, the change of the Fund's name, and the revisions to the Fund's investment policies, the Board of Trustees concluded that the Proposed Index, which measures the performance of growth stocks of developed countries around the world, is a more appropriate Benchmark Index for evaluating the Fund's performance, and better reflects the research team's long-term expectations of finding investment opportunities throughout the world. In approving the change in the Benchmark Index for the Fund, the Trustees considered various information provided by Janus Capital, including, among other 17 information: (1) the dollar amount of the pro forma advisory fee that would have been paid by the Fund, before and after all applicable waivers, for the period from March 1, 2006 through July 31, 2006 using the Current Index as the Benchmark Index and based upon a Performance Period beginning with the Fund's inception on February 25, 2005; (2) the dollar amount of the pro forma advisory fee that would have been paid by the Fund, before and after all applicable waivers, using the Proposed Index as the Benchmark Index over the same time period; (3) the difference between the pro forma fees of each index, net of any waivers; (4) a chart that compared the returns of the Current and Proposed Indexes from the Fund's inception through July 31, 2006, which showed that the returns of the Fund have corresponded more closely to those of the Proposed Index over the period; and (5) a chart that compared the calendar year performance of both the Current Index and the Proposed Index for the past five years, which showed that the two benchmarks have performed differently at times over that period. The Trustees also met in executive session with their independent legal counsel to review and discuss the proposed change in the Benchmark Index, and considered information and analysis provided by the Trustees' independent fee consultant. The Trustees concluded that the Proposed Index was a more appropriate Benchmark Index for evaluating the Fund's performance. SHAREHOLDER COMMUNICATIONS The Trustees provide for shareholders to send written communications to the Trustees via regular mail. Written communications to the Trustees, or to an individual Trustee, should be sent to the attention of the Trust's Secretary at the address of the Trust's principal executive office. All such communications received by the Trust's Secretary shall be promptly forwarded to the individual Trustee to whom they are addressed or to the full Board of Trustees, as applicable. If a communication does not indicate a specific Trustee, it will be sent to the Chairperson of the Nominating and Governance Committee and the outside counsel to the Independent Trustees for further distribution as deemed appropriate by such persons. The Trustees may further develop and refine this process as deemed necessary or desirable. FUND SERVICE PROVIDERS WHO SERVES AS MY FUND'S TRANSFER AGENT? Janus Services, P.O. Box 173375, Denver, Colorado 80217, a wholly-owned subsidiary of Janus Capital, serves as the Fund's transfer agent pursuant to an Amended and Restated Transfer Agency Agreement ("Transfer Agency Agreement") between Janus Services and the Trust. Pursuant to the Transfer Agency Agreement, the Fund reimburses Janus Services for out-of-pocket expenses incurred by Janus Services in connection with services rendered. In addition, for services provided, including, but not limited to, establishing and maintaining shareholder accounts, recording ownership of shares on the Trust's books, mailing shareholder reports, recording reinvestments of dividends and distributions, and coordinating with banks, broker-dealers and other 18 financial intermediaries who represent Fund shareholders, Janus Services receives from the Fund an asset-weighted average annual fee based upon the proportion of the Fund's net assets sold directly and the proportion of the Fund's net assets sold through financial intermediaries. The applicable annual fee rates are 0.16% of the daily closing net asset value of Fund shares sold directly to shareholders and 0.21% of the daily closing net asset value of Fund shares sold through financial intermediaries. In addition, the Fund pays Janus Services a monthly fee calculated at an annual rate of $4.00 per open shareholder account. Janus Services intends to continue to provide the same services after implementation of the Proposed Advisory Agreement. The Fund paid $89,076 to Janus Services for the 12-month period ended April 30, 2006. WHO SERVES AS MY FUND'S DISTRIBUTOR? Janus Distributors, a wholly-owned subsidiary of Janus Capital, located at 151 Detroit Street, Denver, Colorado 80206, serves as distributor of the Trust pursuant to an Amended and Restated Distribution Agreement between the Trust and Janus Distributors. Janus Distributors does not receive compensation from the Trust for services rendered. Janus Distributors intends to continue to provide the same services after implementation of the Proposed Advisory Agreement. WHO SERVES AS MY FUND'S ADMINISTRATOR? Janus Capital serves as administrator to the Trust, performing internal accounting, recordkeeping, blue sky monitoring and registration functions of the Trust. Janus Capital may be reimbursed by the Trust for certain administrative and clerical functions it provides to the Fund as well as for reasonable costs it incurs in performing certain functions. Janus Capital intends to continue to provide the same administrative services after implementation of the Proposed Advisory Agreement. ADDITIONAL INFORMATION QUORUM AND VOTING Shareholders of the Fund will vote together at the Meeting. Each holder of a whole or fractional share shall be entitled to one vote for each whole or fractional dollar value of net asset value held in such shareholder's name. If you are not the owner of record, but your shares are instead held for your benefit by a financial intermediary such as a retirement plan service provider, broker-dealer, bank trust department, insurance company, or other financial intermediary, that financial intermediary may request that you provide instruction on how to vote the shares you beneficially own. Your financial intermediary will provide you with additional information. Thirty percent of the outstanding shares entitled to vote at the Meeting shall be a quorum for the transaction of business at the Meeting. Any lesser number is sufficient for adjournments. In the event that the necessary quorum to transact business or the 19 vote required to approve the proposal is not obtained at the Meeting, the persons named as proxies may propose one or more adjournments of the Meeting, in accordance with applicable law, to permit further solicitation of proxies. Any such adjournment will require the affirmative vote of the holders of a majority of the shares of the Fund, present in person or by proxy at the Meeting. The persons named as proxies will vote the proxies (including broker non-votes and abstentions) in favor of adjournment if they determine additional solicitation is warranted and in the interests of the Fund's shareholders. "Broker non-votes" are shares held by a broker or nominee for which an executed proxy is received by the Trust, but are not voted because instructions have not been received from beneficial owners or persons entitled to vote and the broker or nominee does not have discretionary voting power. Abstentions and "broker non-votes" are counted as shares eligible to vote at the Meeting in determining whether a quorum is present, but do not represent votes cast with respect to adjournment or the proposal. Accordingly, assuming the presence of a quorum, abstentions and "broker non-votes" will have the effect of a vote against the proposal. Approval of the proposal will require the affirmative vote of a 1940 Act Majority of the Fund's shareholders eligible to vote at the Meeting. SHARE OWNERSHIP As of the close of business on the Record Date, there were outstanding shares of the Fund with a per share net asset value of $ . Beneficial owners of 5% or more of the outstanding shares of the Fund as of the Record Date are shown below. To the best knowledge of the Trust, no person beneficially owned more than 5% of the outstanding shares of the Fund except as shown below. To the best knowledge of the Trust, entities shown as owning 25% or more of the Fund, unless otherwise indicated, are not the beneficial owners of such shares. <Table> <Caption> NAME AND ADDRESS OF BENEFICIAL OWNER NUMBER OF SHARES PERCENTAGE OF FUND ------------------------------------ ---------------- ------------------ </Table> SOLICITATION OF PROXIES The cost of preparing, printing and mailing the proxy card(s) and this Proxy Statement and all other costs incurred with the solicitation of proxies, including any additional solicitation made by letter, telephone, or otherwise will be paid by Janus Capital. In addition to solicitation by mail, officers and representatives of the Trust, officers and employees of Janus Capital or its affiliates, and certain financial services firms and their representatives, without extra compensation, may conduct additional solicitations personally, by telephone, or by any other means available. 20 Janus Capital has engaged D.F. King & Co., Inc. ("D.F. King"), a professional proxy solicitation firm, to assist in the solicitation of proxies, at an estimated cost of $ , plus expenses. Such expenses will be paid by Janus Capital. Among other things, D.F. King will be: (i) required to maintain the confidentiality of all shareholder information; (ii) prohibited from selling or otherwise disclosing shareholder information to any third party; and (iii) required to comply with applicable telemarketing laws. Brokers, banks, and other fiduciaries may be required to forward soliciting material to their principals on behalf of the Fund and to obtain authorization for the execution of proxies. For those services, they will be reimbursed by Janus Capital for their expenses to the extent Janus Capital or the Fund would have directly borne those expenses. As the Meeting date approaches, certain shareholders whose votes have not been received, may receive telephone calls from a representative of D.F. King. Authorization to permit D.F. King to execute proxies may be obtained by telephonic or electronically transmitted instructions from shareholders of the Fund. Proxies that are obtained telephonically will be recorded in accordance with the procedures described below. The Fund believes that these procedures are reasonably designed to ensure that both the identity of the shareholder casting the vote and the voting instructions of the shareholder are accurately determined. In all cases where a telephonic proxy is solicited, the representative is required to ask for each shareholder's full name, address, title (if the shareholder is authorized to act on behalf of an entity, such as a corporation), and to confirm that the shareholder has received the Proxy Statement and proxy card(s) in the mail. If the information solicited agrees with the information provided to D.F. King, then the D.F. King representative has the responsibility to explain the process, read the proposal listed on the proxy card, and ask for the shareholder's instructions on the proposal. Although the D.F. King representative is permitted to answer questions about the process, he or she is not permitted to recommend to the shareholder how to vote. The D.F. King representative may read any recommendation set forth in this Proxy Statement. The D.F. King representative will record the shareholder's instructions. Within 72 hours, the shareholder will be sent a confirmation of his or her vote asking the shareholder to call D.F. King immediately if his or her instructions are not accurately reflected in the confirmation. Telephone Touch-Tone Voting. Shareholders may provide their voting instructions through telephone touch-tone voting by following the instructions on the enclosed proxy card(s). Shareholders will have an opportunity to review their voting instructions and make any necessary changes before submitting their voting instructions and terminating their telephone call. Internet Voting. Shareholders may provide their voting instructions through Internet voting by following the instructions on the enclosed proxy card(s). Shareholders who vote via the Internet, in addition to confirming their voting instructions prior to submission and terminating their Internet link, will, upon request, receive an e-mail 21 confirming their voting instructions. If a shareholder wishes to participate in the Meeting but does not wish to give a proxy by telephone or via the Internet, the shareholder may still submit the proxy card(s) originally sent with the Proxy Statement in the postage paid envelope provided, or attend the Meeting in person. Shareholders requiring additional information regarding the proxy or replacement proxy card(s), may contact D.F. King at [TOLL-FREE NUMBER]. Any proxy given by a shareholder is revocable until voted at the Meeting. Revoking a Proxy. Any shareholder submitting a proxy has the power to revoke it at any time before it is exercised by submitting to the Secretary of the Trust at 151 Detroit Street, Denver, Colorado 80206, a written notice of revocation or a subsequently executed proxy or by attending the Meeting and voting in person. All properly executed and unrevoked proxies received in time for the Meeting will be voted as specified in the proxy, or, if no specification is made, will be voted FOR the proposal described in this Proxy Statement. Shares Held by Accounts of Insurance Companies. Shares of the Fund may be held by certain separate accounts of insurance companies to fund benefits payable under certain variable annuity contracts and variable life insurance policies. Your insurance company may request that you provide it with voting instructions for your beneficially held shares of any such separate account. If you do not provide voting instructions to your insurance company, it may vote all of the shares held in that separate account in the same proportions as the voting actually received from other variable contract holders for that separate account. PORTFOLIO TRANSACTIONS All orders for the purchase or sale of a Fund's portfolio securities are placed on behalf of the Fund by Janus Capital, or its agent. The Fund does not allocate portfolio transactions on the basis of the sale of Fund shares, although brokerage firms whose customers purchase shares of the Fund may execute transactions for the Fund and receive brokerage commissions. LEGAL MATTERS Information regarding material pending legal proceedings involving Janus Capital or the Fund is attached as [Exhibit E] to this Proxy Statement. SHAREHOLDER PROPOSAL FOR SUBSEQUENT MEETINGS The Fund is not required, and does not intend, to hold annual shareholder meetings. Under the terms of a settlement reached between Janus Capital and the SEC in August 2004, commencing in 2005 and not less than every fifth calendar year thereafter, the Trust will hold a meeting of shareholders to elect Trustees. Shareholder meetings may be called from time to time as described in the Amended and Restated Agreement and Declaration of Trust and the Trust's Amended and Restated Bylaws. Under the proxy rules of the SEC, shareholder proposals that meet certain conditions 22 may be included in the Fund's proxy statement for a particular meeting. Those rules currently require that for future meetings, the shareholder must be a record or beneficial owner of the Fund shares either (i) with a value of at least $2,000 or (ii) in an amount representing at least 1% of the Fund's securities to be voted, at the time the proposal is submitted and for one year prior thereto, and must continue to own such shares through the date on which the meeting is held. Another requirement relates to the timely receipt by the Fund of any such proposal. Under those rules, a proposal must have been submitted within a reasonable time before the Fund began to print and mail this Proxy Statement in order to be included in this Proxy Statement. A proposal submitted for inclusion in the Fund's proxy material for the next special meeting after the meeting to which this Proxy Statement relates must be received by the Fund within a reasonable time before the Fund begins to print and mail the proxy materials for that meeting. Shareholders wishing to submit a proposal for inclusion in a proxy statement subsequent to the Meeting, if any, should send their written proposal to the Secretary of the Trust at 151 Detroit Street, Denver, Colorado 80206 within a reasonable time before the Fund begins to print and mail the proxy materials for that meeting. Notice of shareholder proposals to be presented at the Meeting must have been received within a reasonable time before the Fund began to mail this Proxy Statement. The timely submission of a proposal does not guarantee its inclusion in the proxy materials. 23 REPORTS TO SHAREHOLDERS AND FINANCIAL STATEMENTS The Annual Report to shareholders of the Fund, including financial statements of the Fund, has previously been sent to shareholders.

JANUS CAPITAL MANAGEMENT LLC By: ---------------------------------- David R. Martin, Chief Financial Officer and Executive Vice President JANUS INVESTMENT FUND By: ---------------------------------- Kelley A. Howes, President and Chief Executive Officer A-5 SCHEDULE A PERFORMANCE ADJUSTMENT [BEGINNING][(COMMENCING] WITH [THE BASE FEE][MONTHLY FEES] PAYABLE FOR JANUARY [2006 AND IN MONTH 13 FROM THE AMENDED DATE OF THIS AGREEMENT, THE BASE FEE SHALL BE][2007)] [The monthly fee shall consist of the Base Fee, as] adjusted[ monthly] based upon the investment performance of the Fund in relation to the cumulative investment record of [the Fund's][one or more] benchmark[, the Russell 1000 Index (the "Index"),] [indexes] over the "Performance Period" (such adjustment being referred to herein as the "Performance Adjustment")[ as described below.] The "Performance Period" is defined as the shorter of: (a) the period from [the date of this Agreement][January 1, 2006] through the end of the month [preceding the month] for which the fee is being calculated[, and]; [or] (b) the 36 month period preceding[ the end of] the month for which the fee is being calculated. [The Russell 1000 Index (the "Prior Index") is the benchmark through [December 31, 2006]; and the Morgan Stanley Capital International World Growth Index (the "Successor Index") is the benchmark commencing [January 1, 2007]. Therefore, in calculating the Performance Adjustment for any Performance Period that commences prior to January 1, 2007, the Prior Index shall be used for that portion of the period preceding that date, and, for any Performance Period that ends after [December 31, 2006], the Successor Index shall be used for that portion of the period subsequent to that date.] [The Performance Adjustment shall be calculated by subtracting the investment record of the Index from the investment performance of the Fund. If there is less than a 0.50% difference (plus or minus) between the investment performance of the Fund and the investment record of the Index, the Fund pays JCM the Base Fee with no adjustment. If the difference between the investment performance of the Fund and the investment record of the Index is 0.50% or greater during any Performance Period, the Base Fee will be subject to an upward or downward performance adjustment of 1/12 of 0.0125% for every full 0.50% increment by which the Fund outperforms or underperforms the Index. The maximum percentage used in calculating the Performance Adjustment (positive or negative) in any month is 1/12 of 0.15%. The Performance Adjustment is applied against the Fund's average daily net assets during the Performance Period.] [The Performance Adjustment for any month commencing in January 2007 shall be derived from the difference between: (1) the positive or negative Total Return of the Measuring Class of shares of the Fund over the Performance Period ending at the end of the next preceding month, less (2) the positive or negative percentage change in the benchmark index over that period (or sum of the percentage changes in the benchmark indexes if two benchmarks are used during that period). If the difference is less than a positive or negative 0.50%, the Fund shall pay the Base Fee for that month, without a Performance Adjustment. If the difference is 0.50% or more, the Fund shall pay the A-6 Base Fee plus or minus a Performance Adjustment of 1/12 of 0.0125% (or approximately 0.00104%) for each full positive or negative 0.50% of the Performance Adjustment multiplied by the average daily net assets of the Fund during the Performance Period, provided, however, that a Performance Adjustment for any month shall not exceed 1/12 of .15% (or 0.0125%) of the average net assets during the Performance Period.] For purposes of computing the Base Fee and [the Performance Adjustment][any adjustment], net assets are averaged over different periods (average daily net assets during the relevant month for the Base Fee versus average daily net assets during the Performance Period for the [Performance Adjustment][adjustment]). The Base Fee is calculated and accrued daily. The [Performance Adjustment][adjustment] is calculated monthly in arrears and is accrued evenly each day throughout the month. The investment advisory fee is paid monthly in arrears. The average daily net asset value of the Fund, or any class thereof, shall be determined in the manner set forth in the Trust's Amended and Restated Agreement and Declaration of Trust, Amended and Restated Bylaws and registration statement, each as may be amended from time to time. The [investment performance][Total Return of the Measuring Class of shares] of the Fund will be the sum of: (1) the change in the [Fund's ]net asset value [("NAV") ]per share [of the Measuring Class ("NAV")] during the Performance Period; plus (2) the value of the [Fund's cash][per share] distributions [per share ]accumulated [to][on] the [end of][Measuring Class during] the Performance Period; plus (3) the value of capital gains taxes per share paid or payable on undistributed realized long-term capital gains accumulated to the end of the Performance Period; expressed as a percentage of the Fund's NAV per share at the beginning of the Performance Period. For this purpose, the value of distributions per share of realized capital gains, of dividends per share paid from investment income and of capital gains taxes per share paid or payable on undistributed realized long-term capital gains shall be treated as reinvested in shares of the Fund at the NAV in effect at the close of business on the record date for the payment of such distributions and dividends and the date on which provision is made for such taxes, after giving effect to such distributions, dividends and taxes. The [investment record of the Index][change in the benchmark index or indexes] will be the sum of: (1) the change in the level of the [Index][index (or the blended change in the level of the indexes, as applicable)] during the Performance Period; plus (2) the value, computed consistently with the [Index][index], of cash distributions made by companies whose securities comprise the [Index][index] accumulated A-7 to the end of the Performance Period[;] [(or, as applicable, the value of cash distributions made by companies whose securities comprise the Prior Index, accumulated through December 31, 2006, plus the value of cash distributions made by companies whose securities comprise the Successor Index, accumulated on and after January 1, 2007 to the end of the Performance Period, in each computed consistently with the respective index)], expressed as a percentage of the [Index][index] level at the beginning of the Performance Period. For this purpose, cash distributions on the securities which comprise the [Index][index] shall be treated as reinvested in the [Index][index] at least as frequently as the end of each calendar quarter following the payment of the dividend. [If, consistent with the Trust's Amended and Restated Agreement and Declaration of Trust and Amended and Restated Bylaws, each as may be further amended, the Trustees should subsequently decide to divide][The "Measuring Class" of] shares of the Fund [into two or more separate classes,][shall initially be] the oldest class of shares[ will be used for purposes of determining the Performance Adjustment][.] From time to time, the Trustees may, by vote of the Trustees of the Trust voting in person, including a majority of the Trustees who are not parties to this Agreement or "interested persons" (as defined in the 1940 Act) of any such parties, determine that a different class of shares of the Fund is the most appropriate for use in calculating the Performance Adjustment. If a different class of shares ("Successor Class") is substituted in calculating the Performance Adjustment, the use of that Successor Class of shares for purposes of calculating the Performance Adjustment may apply to the entire Performance Period so long as such Successor Class was outstanding at the beginning of such period. If the Successor Class of shares was not outstanding for all or a portion of the Performance Period, it may only be used in calculating that portion of the Performance Adjustment attributable to the period during which such Successor Class was outstanding and any prior portion of the Performance Period shall be calculated using the class of shares previously designated.
