RISK/RETURN SUMMARY
- --------------------------------------------------------------------------------


JANUS ORION FUND



1. WHAT IS THE INVESTMENT OBJECTIVE OF JANUS ORION FUND?


               The Fund seeks long-term growth of capital.

               The Fund's Trustees may change this objective without a
               shareholder vote and the Fund will notify you of any changes that
               are material. If there is a material change in the Fund's
               objective or policies, you should consider whether the Fund
               remains an appropriate investment for you. There is no guarantee
               that the Fund will meet its objective.


2. WHAT ARE THE MAIN INVESTMENT STRATEGIES OF JANUS ORION FUND?



               The Fund invests primarily in common stocks selected for their
               growth potential. The Fund may invest in companies of any size,
               from larger, well-established companies to smaller, emerging
               growth companies. The Fund normally concentrates its investments
               in a core group of 20-30 common stocks.



               The Fund may invest without limit in foreign equity and debt
               securities and will invest less than 35% of its net assets in
               high-yield/high-risk bonds.



               The portfolio manager applies a "bottom up" approach in choosing
               investments. In other words, he looks for companies with earnings
               growth potential one at a time. If the portfolio manager is
               unable to find such investments, a significant portion of the
               Fund's assets may be in cash or similar investments.



3. WHAT ARE THE MAIN RISKS OF INVESTING IN JANUS ORION FUND?


               The biggest risk of investing in this Fund is that its returns
               may vary and you could lose money. If you are considering
               investing in the Fund, remember that it is designed for long-term
               investors who can accept the risks of investing in a portfolio
               with significant common stock holdings. Common stocks tend to be
               more volatile than other investment choices.

               The value of the Fund's portfolio may decrease if the value of an
               individual company in the portfolio decreases. The value of the


 2 Janus Orion Fund prospectus

<PAGE>

               Fund's portfolio could also decrease if the stock market goes
               down. If the value of the Fund's portfolio decreases, the Fund's
               net asset value (NAV) will also decrease which means if you sell
               your shares in the Fund you would get back less money.

               The Fund is nondiversified. In other words, it may hold larger
               positions in a smaller number of securities than a diversified
               fund. As a result, a single security's increase or decrease in
               value may have a greater impact on the Fund's NAV and total
               return. Since the Fund normally concentrates in a core portfolio
               of 20-30 stocks, this risk may be increased.

               An investment in the Fund is not a bank deposit and is not
               insured or guaranteed by the Federal Deposit Insurance
               Corporation or any other government agency.


               Since the Fund will commence operations on June 30, 2000, there
               is no performance available as of the date of this Prospectus.

FEES AND EXPENSES

               SHAREHOLDER FEES, such as sales loads, redemption fees or
               exchange fees, are charged directly to an investor's account. All
               Janus funds are no-load investments, so you will not pay any
               shareholder 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 example
               below shows, these costs are borne indirectly by all
               shareholders.


This table describes the fees and expenses that you may pay if you buy and hold
shares of the Fund.

  This example is intended to help you compare the cost of investing in the
  Fund with the cost of investing in other mutual funds. The example
  assumes that you invest $10,000 in the Fund for the time periods
  indicated then redeem all of your shares at the end of those periods. The
  example also assumes that your investment has a 5% return each year and
  that the Fund's operating expenses remain the same. Although your actual
  costs may be higher or lower, based on these assumptions your costs would

STRATEGIES AND RISKS
- --------------------------------------------------------------------------------

               This section takes a closer look at the investment objective of
               the Fund, its principal investment strategies and certain risks
               of investing in the Fund. Strategies and policies that are noted
               as "fundamental" cannot be changed without a shareholder vote.

               Please carefully review the "Risks" section of this Prospectus on
               pages 8-11 for a discussion of risks associated with certain
               investment techniques. We've also included a Glossary with
               descriptions of investment terms used throughout this Prospectus.

INVESTMENT OBJECTIVE AND PRINCIPAL INVESTMENT STRATEGIES


               Janus Orion Fund seeks long-term growth of capital. It pursues
               its objective by investing primarily in common stocks selected
               for their growth potential. The Fund may invest in companies of
               any size, from larger, well-established companies to smaller,
               emerging growth companies. The Fund normally concentrates its
               investments in a core group of 20-30 common stocks.


               The Fund may invest substantially all of its assets in common
               stocks if its portfolio manager believes that common stocks will
               appreciate in value. The portfolio manager generally takes a
               "bottom up" approach to selecting companies. In other words, he
               seeks to identify individual companies with earnings growth
               potential that may not be recognized by the market at large. He
               makes this assessment by looking at companies one at a time,
               regardless of size, country of organization, place of principal
               business activity, or other similar selection criteria.
               Realization of income is not a significant consideration when
               choosing investments for the Fund. Income realized on the Fund's
               investments will be incidental to its objective.

               Foreign securities are generally selected on a stock-by-stock
               basis without regard to any defined allocation among countries or
               geographic regions. However, certain factors such as expected
               levels of inflation, government policies influencing business
               conditions, the outlook for currency relationships, and prospects
               for economic growth among countries, regions or geographic areas
               may warrant greater consideration in selecting foreign
               securities.


                                                  Janus Orion Fund prospectus  5

<PAGE>

               There are no limitations on the countries in which the Fund may
               invest and the Fund may at times have significant foreign
               exposure.

GENERAL PORTFOLIO POLICIES

               In investing its portfolio assets, the Fund will follow the
               general policies listed below. The percentage limitations
               included in these policies and elsewhere in this Prospectus apply
               only at the time of purchase of the security. So, for example, if
               the Fund exceeds a limit as a result of market fluctuations or
               the sale of securities, it will not be required to dispose of any
               securities.

               CASH POSITION
               When the Fund's portfolio manager believes that market conditions
               are unfavorable for profitable investing, or when he is otherwise
               unable to locate attractive investment opportunities, the Fund's
               cash or similar investments may increase. In other words, the
               Fund does not always stay fully invested in stocks. Cash or
               similar investments generally are a residual - they represent the
               assets that remain after the portfolio manager has committed
               available assets to desirable investment opportunities. However,
               the portfolio manager may also temporarily increase the Fund's
               cash position to protect its assets or maintain liquidity. When
               the Fund's investments in cash or similar investments increase,
               it may not participate in market advances or declines to the same
               extent that it would if the Fund remained more fully invested in
               stocks.

               OTHER TYPES OF INVESTMENTS
               The Fund invests primarily in domestic and foreign equity
               securities, which may include preferred stocks, common stocks,
               warrants and securities convertible into common or preferred
               stocks, but it may also invest to a lesser degree in other types
               of securities. These securities (which are described in the
               Glossary) may include:

               - debt securities

               - indexed/structured securities


 6 Janus Orion Fund prospectus

<PAGE>

               - high-yield/high-risk bonds (less than 35% of the Fund's assets)

               - options, futures, forwards, swaps and other types of
                 derivatives for hedging purposes or for non-hedging purposes
                 such as seeking to enhance return

               - securities purchased on a when-issued, delayed delivery or
                 forward commitment basis

               ILLIQUID INVESTMENTS
               The Fund may invest up to 15% of its net assets in illiquid
               investments. An illiquid investment is a security or other
               position that cannot be disposed of quickly in the normal course
               of business. For example, some securities are not registered
               under the U.S. securities laws and cannot be sold to the U.S.
               public because of SEC regulations (these are known as "restricted
               securities"). Under procedures adopted by the Fund's Trustees,
               certain restricted securities may be deemed liquid, and will not
               be counted toward this 15% limit.

               FOREIGN SECURITIES
               The Fund may invest without limit in foreign equity and debt
               securities. The Fund may invest directly in foreign securities
               denominated in a foreign currency and not publicly traded in the
               United States. Other ways of investing in foreign securities
               include depositary receipts or shares, and passive foreign
               investment companies.

               SPECIAL SITUATIONS
               The Fund may invest in special situations. A special situation
               arises when, in the opinion of the Fund's portfolio manager, the
               securities of a particular issuer will be recognized and
               appreciate in value due to a specific development with respect to
               that issuer. Developments creating a special situation might
               include, among others, a new product or process, a technological
               breakthrough, a management change or other extraordinary
               corporate event, or differences in market supply of and demand
               for the security. The Fund's performance could suffer if the
               anticipated development in


                                                  Janus Orion Fund prospectus  7

<PAGE>

               a "special situation" investment does not occur or does not
               attract the expected attention.

               PORTFOLIO TURNOVER
               The Fund generally intends to purchase securities for long-term
               investment although, to a limited extent, the Fund may purchase
               securities in anticipation of relatively short-term price gains.
               Short-term transactions may also result from liquidity needs,
               securities having reached a price or yield objective, changes in
               interest rates or the credit standing of an issuer, or by reason
               of economic or other developments not foreseen at the time of the
               investment decision. The Fund may also sell one security and
               simultaneously purchase the same or a comparable security to take
               advantage of short-term differentials in bond yields or
               securities prices. Changes are made in the Fund's portfolio
               whenever its portfolio manager believes such changes are
               desirable. Portfolio turnover rates are generally not a factor in
               making buy and sell decisions.

               Increased portfolio turnover may result in higher costs for
               brokerage commissions, dealer mark-ups and other transaction
               costs and may also result in taxable capital gains. Higher costs
               associated with increased portfolio turnover may offset gains in
               the Fund's performance.

RISKS


               Because the Fund may invest substantially all of its assets in
               common stocks, the main risk is the risk that the value of the
               stocks it holds might decrease in response to the activities of
               an individual company or in response to general market and/or
               economic conditions. If this occurs, the Fund's share price may
               also decrease. The Fund's performance may also be affected by
               risks specific to certain types of investments, such as foreign
               securities, derivative investments, non-investment grade bonds,
               initial public offerings (IPOs), or companies with relatively
               small market capitalizations. IPOs and other investment
               techniques may have a magnified performance impact on a fund with
               a small asset

               base. A fund may not experience similar performance as its assets
               grow.

The following questions and answers are designed to help you better understand
some of the risks of investing in the Fund.

1. HOW DOES THE NONDIVERSIFIED STATUS OF THE FUND AFFECT ITS RISK?


               Diversification is a way to reduce risk by investing in a broad
               range of stocks or other securities. Since the Fund is
               "nondiversified," it has the ability to take larger positions in
               a smaller number of issuers. Because the appreciation or
               depreciation of a single stock may have a greater impact on the
               Fund's NAV, its share price can be expected to fluctuate more
               than a comparable diversified fund. This fluctuation, if
               significant, may affect the performance of the Fund.



2. THE FUND MAY INVEST IN SMALLER OR NEWER COMPANIES. DOES THIS CREATE ANY
   SPECIAL RISKS?


               Many attractive investment opportunities may be smaller, start-up
               companies offering emerging products or services. Smaller or
               newer companies may suffer more significant losses as well as
               realize more substantial growth than larger or more established
               issuers because they may lack depth of management, be unable to
               generate funds necessary for growth or potential development, or
               be developing or marketing new products or services for which
               markets are not yet established and may never become established.
               In addition, such companies may be insignificant factors in their
               industries and may become subject to intense competition from
               larger or more established companies. Securities of smaller or
               newer companies may have more limited trading markets than the
               markets for securities of larger or more established issuers, and
               may be subject to wide price fluctuations. Investments in such
               companies tend to be more volatile and somewhat more speculative.

3. HOW DOES THE FUND TRY TO REDUCE RISK?



               The Fund may use futures, options, swaps and other derivative
               instruments to "hedge" or protect its portfolio from adverse
               movements in securities prices and interest rates. The Fund may
               also use a variety of currency hedging techniques, including
               forward currency contracts, to manage exchange rate risk. The
               portfolio manager believes the use of these instruments will
               benefit the Fund. However, the Fund's performance could be worse
               than if the Fund had not used such instruments if the portfolio
               manager's judgement proves incorrect. Risks associated with the
               use of derivative instruments are described in the SAI.



4. HOW COULD THE FUND'S INVESTMENTS IN FOREIGN SECURITIES AFFECT ITS
   PERFORMANCE?


               The Fund may invest without limit in foreign securities either
               indirectly (e.g., depositary receipts) or directly in foreign
               markets. Investments in foreign securities, including those of
               foreign governments, may involve greater risks than investing in
               domestic securities because the Fund's performance may depend on
               issues other than the performance of a particular company. These
               issues include:

               - currency risk

               - political and economic risk

               - regulatory risk

               - market risk

               - transaction costs

               These risks are described in the SAI.

5. ARE THERE SPECIAL RISKS ASSOCIATED WITH INVESTMENTS IN HIGH-YIELD/HIGH-RISK
   BONDS?

               High-yield/high-risk bonds (or "junk" bonds) are bonds rated
               below investment grade by the primary rating agencies such as
               Standard & Poor's and Moody's. The value of lower quality bonds


 10 Janus Orion Fund prospectus

<PAGE>

               generally is more dependent on credit risk, or the ability of the
               issuer to meet interest and principal payments, than investment
               grade bonds. Issuers of high-yield bonds may not be as strong
               financially as those issuing bonds with higher credit ratings and
               are more vulnerable to real or perceived economic changes,
               political changes or adverse developments specific to the issuer.

               Please refer to the SAI for a description of bond rating
               categories.

TYPES OF ACCOUNT OWNERSHIP

               If you are investing in the Fund for the first time, you will
               need to establish an account. You can establish the following
               types of accounts by completing a New Account Application.

               INDIVIDUAL OR JOINT OWNERSHIP
               Individual accounts are owned by one person. Joint accounts have
               two or more owners.

               A GIFT OR TRANSFER TO MINOR (UGMA OR UTMA)
               An UGMA/UTMA is a custodial account managed for the benefit of a
               minor. To open an UGMA or UTMA, you must include the minor's
               Social Security number on the application.

               TRUST
               An established trust can open an account. The names of each
               trustee, the name of the trust and the date of the trust
               agreement must be included on the application.

                                                        Shareholder's manual  15
<PAGE>

               BUSINESS ACCOUNTS
               Corporations and partnerships may also open an account. The
               application must be signed by an authorized officer of the
               corporation or a general partner of the partnership.

TAX-DEFERRED ACCOUNTS

               If you are eligible, you may set up one or more tax-deferred
               accounts. A tax-deferred account allows you to shelter your
               investment income and capital gains from current income taxes. A
               contribution to certain of these plans may also be tax
               deductible. Tax-deferred accounts include retirement plans
               described below and the Education IRA. Please refer to the Janus
               retirement guide for more complete information regarding the
               different types of IRAs, including the Education IRA.
               Distributions from these plans are generally subject to income
               tax and may be subject to an additional tax if withdrawn prior to
               age 59 1/2 or used for a nonqualifying purpose. Investors should
               consult their tax adviser or legal counsel before selecting a
               tax-deferred account.

               Investors Fiduciary Trust Company serves as custodian for the
               tax-deferred accounts offered by the Fund. You will be charged an
               annual account maintenance fee of $12 for each taxpayer
               identification number no matter how many tax-deferred accounts
               you have with Janus. You may pay the fee by check or have it
               automatically deducted from your account (usually in December).
               The custodian reserves the right to change the amount of this fee
               or to waive it in whole or in part for certain types of accounts.

               TRADITIONAL AND ROTH INDIVIDUAL RETIREMENT ACCOUNTS
               Both types of IRAs allow most individuals with earned income to
               contribute up to the lesser of $2,000 ($4,000 for most married
               couples) or 100% of compensation annually.

               EDUCATION IRA
               This plan allows individuals, subject to certain income
               limitations, to contribute up to $500 annually on behalf of any
               child under the age of 18.

               SIMPLIFIED EMPLOYEE PENSION PLAN
               This plan allows small business owners (including sole
               proprietors) to make tax-deductible contributions for themselves
               and any eligible employee(s). A SEP requires an IRA (a SEP-IRA)
               to be set up for each SEP participant.

               PROFIT SHARING OR MONEY PURCHASE PENSION PLAN
               These plans are open to corporations, partnerships and sole
               proprietors to benefit their employees and themselves.

               SECTION 403(B)(7) PLAN
               Employees of educational organizations or other qualifying, tax-
               exempt organizations may be eligible to participate in a Section
               403(b)(7) Plan.

PAYING FOR SHARES

Please note the following when purchasing shares:

- - Cash, credit cards, third party checks, travelers cheques, credit card checks
  or money orders will not be accepted.

- - All purchases must be made in U.S. dollars and checks must be drawn on U.S.
  banks.

- - We may make additional attempts to debit the bank account for ACH purchases.

- - The Fund reserves the right to reject any specific purchase request.


- - If all or a portion of a check is received for investment without a specific
  fund designation, for investment in one of our closed funds, or for investment
  in a fund that is not yet available for public sale, the undesignated amount
  or entire investment, as applicable, will be invested in the Janus Money
  Market Fund - Investor Shares. Shares that are subsequently exchanged from
  Janus Money Market Fund - Investor Shares into the selected fund will receive
  the NAV next calculated after your order is received and accepted by the fund.


- - If your purchase is cancelled, you will be responsible for any losses or fees
  imposed by your bank and losses that may be incurred as a result of any
  decline in the value of the cancelled purchase.

EXCHANGE POLICIES

The exchange privilege is not intended as a vehicle for short-term or excessive
trading. The Fund does not permit excessive trading or market timing. Excessive
purchases, redemptions, or exchanges of Fund shares disrupt portfolio management
and drive Fund expenses higher.

Please note the following when exchanging shares:

- - Except for Systematic Exchanges, new accounts established by exchange must be
  opened with $2,500 or the total account value if the value of the account you
  are exchanging from is less than $2,500.

- - Exchanges between existing accounts must meet the $100 subsequent investment
  requirement.

- - You may make four exchanges out of the Fund during a calendar year (exclusive
  of Systematic Exchange). Exchanges in excess of this limit are considered
  excessive trading and may be subject to an exchange fee or may result in
  termination of the exchange privilege or the right to make future purchases of
  Fund shares.

- - The Fund reserves the right to reject any purchase order or exchange request
  and to modify or terminate the exchange privilege at any time. For example,
  the Fund may reject exchanges from accounts engaged in or known to engage in
  trading in excess of the limit above (including market timing transactions) or
  whose trading has been or may be disruptive to the Fund.

- - Exchanges between accounts will be accepted only if the registrations are
  identical.

- - If the shares you are exchanging are held in certificate form, you must return
  the certificate to Janus prior to making any exchanges. Effective June 4,
  1999, shares are no longer available in certificate form.

- - An exchange represents the sale of shares from one fund and the purchase of
  shares of another fund, which may produce a taxable gain or loss in a
  non-retirement account.

- - If the balance in the account you are exchanging from falls below the
  systematic exchange amount, all remaining shares will be exchanged
  and the program will be discontinued.

PAYMENT OF REDEMPTION PROCEEDS

- - BY CHECK - Redemption proceeds will be sent to the shareholder(s) of record at
  the address of record within seven days after receipt of a valid redemption
  request. During the 10 days following an address change, checks sent to a new
  address require a signature guarantee.

- - BY ELECTRONIC TRANSFER - If you have established the electronic redemption
  option, your redemption proceeds can be electronically transferred to your
  predesignated bank account on the next bank business day after receipt of your
  redemption request (wire transfer) or the second bank business day after
  receipt of your redemption request (ACH transfer).
Wire transfers will be charged an $8 fee per wire and your bank may charge an
additional fee to receive the wire. Wire redemptions are not available for
retirement accounts.

IF THE SHARES BEING REDEEMED WERE PURCHASED BY CHECK, TELEPHONE, ON OUR WEB
SITE, OR THROUGH THE AUTOMATIC MONTHLY INVESTMENT PROGRAM, THE FUND MAY DELAY
THE PAYMENT OF YOUR REDEMPTION PROCEEDS FOR UP TO 15 DAYS FROM THE DAY OF
PURCHASE TO ALLOW THE PURCHASE TO CLEAR. Unless you provide alternate
instructions, your proceeds will be invested in Janus Money Market
Fund - Investor Shares during the 15 day hold period.

WRITTEN INSTRUCTIONS

               To redeem or exchange all or part of your shares in writing, your
               request should be sent to one of the addresses listed on page 14
               and must include the following information:

               - the name of the Fund(s)

               - the account number(s)

               - the amount of money or number of shares being redeemed or
                 exchanged

               - the name(s) on the account

               - the signature(s) of all registered account owners (see account
                 application for signature requirements)

               - your daytime telephone number

SIGNATURE GUARANTEE

               A SIGNATURE GUARANTEE IS REQUIRED if any of the following is
               applicable:

               - You request a redemption by check that exceeds $100,000.

               - You would like a check made payable to anyone other than the
                 shareholder(s) of record.

               - You would like a check mailed to an address which has been
                 changed within 10 days of the redemption request.

               - You would like a check mailed to an address other than the
                 address of record.

               THE FUND RESERVES THE RIGHT TO REQUIRE A SIGNATURE GUARANTEE
               UNDER OTHER CIRCUMSTANCES OR TO REJECT OR DELAY A REDEMPTION ON
               CERTAIN LEGAL GROUNDS.

               HOW TO OBTAIN A SIGNATURE GUARANTEE

               A signature guarantee assures that a signature is genuine. The
               signature guarantee protects shareholders from unauthorized
               account transfers. The following financial institutions may
               guaran-

 22 Shareholder's manual
<PAGE>

               tee signatures: banks, savings and loan associations, trust
               companies, credit unions, broker-dealers, and member firms of a
               national securities exchange. Call your financial institution to
               see if they have the ability to guarantee a signature. A
               signature guarantee cannot be provided by a notary public.

               If you live outside the United States, a foreign bank properly
               authorized to do business in your country of residence or a U.S.
               consulate may be able to authenticate your signature.

PRICING OF FUND SHARES

               All purchases, redemptions and exchanges will be processed at the
               NAV next calculated after your request is received and accepted
               by the Fund (or the Fund's agent or authorized designee). The
               Fund's NAV is calculated at the close of the regular trading
               session of the NYSE (normally 4:00 p.m. New York time) each day
               that the NYSE is open. The NAV of Fund shares is not determined
               on days the NYSE is closed (generally New Year's Day, Martin
               Luther King Day, Presidents' Day, Good Friday, Memorial Day,
               Independence Day, Labor Day, Thanksgiving and Christmas). In
               order to receive a day's price, your order must be received by
               the close of the regular trading session of the NYSE. Securities
               are valued at market value or, if a market quotation is not
               readily available, at their fair value determined in good faith
               under procedures established by and under the supervision of the
               Trustees. Short-term instruments maturing within 60 days are
               valued at amortized cost, which approximates market value. See
               the SAI for more detailed information.

SHAREHOLDER SERVICES AND ACCOUNT POLICIES

               ACCOUNT MINIMUMS

               Due to the proportionately higher costs of maintaining small
               accounts, Janus reserves the right to deduct a $10 minimum
               balance fee (or the value of the account if less than $10) from
               accounts with values below the minimums described on page 15 or
               to close such accounts. This policy will apply to accounts

                                                        Shareholder's manual  23
<PAGE>

               participating in the Automatic Monthly Investment Program only if
               your account balance does not reach the required minimum initial
               investment or falls below such minimum and you have discontinued
               monthly investments. This policy does not apply to accounts that
               fall below the minimums solely as a result of market value
               fluctuations. It is expected that, for purposes of this policy,
               accounts will be valued in September, and the $10 fee will be
               assessed on the second Friday of September of each year. You will
               receive notice before we charge the $10 fee or close your account
               so that you may increase your account balance to the required
               minimum.

               TRANSACTIONS THROUGH PROCESSING ORGANIZATIONS

               You may purchase or sell Fund shares through a broker-dealer,
               bank or other financial institution, or an organization that
               provides recordkeeping and consulting services to 401(k) plans or
               other employee benefit plans (a "Processing Organization").
               Processing Organizations may charge you a fee for this service
               and may require different minimum initial and subsequent
               investments than the Fund. Processing Organizations may also
               impose other charges or restrictions different from those
               applicable to shareholders who invest in the Fund directly. A
               Processing Organization, rather than its customers, may be the
               shareholder of record of your shares. The Fund is not responsible
               for the failure of any Processing Organization to carry out its
               obligations to its customers. Certain Processing Organizations
               may receive compensation from Janus Capital or its affiliates and
               certain Processing Organizations may receive compensation from
               the Fund for shareholder recordkeeping and similar services.

               TAXPAYER IDENTIFICATION NUMBER

               On the application or other appropriate form, you will be asked
               to certify that your Social Security or taxpayer identification
               number is correct and that you are not subject to backup
               withholding for failing to report income to the IRS. If you are
               subject to the 31% backup withholding or you did not certify

 24 Shareholder's manual
<PAGE>

               your taxpayer identification number, the IRS requires the Fund to
               withhold 31% of any dividends paid and redemption or exchange
               proceeds. In addition to the 31% backup withholding, you may be
               subject to a $50 fee to reimburse the Fund for any penalty that
               the IRS may impose.

               INVOLUNTARY REDEMPTIONS

               The Fund reserves the right to close an account if the
               shareholder is deemed to engage in activities which are illegal
               or otherwise believed to be detrimental to the Fund.

               TELEPHONE TRANSACTIONS

               You may initiate many transactions by telephone. The Fund and its
               agents will not be responsible for any losses resulting from
               unauthorized transactions when procedures designed to verify the
               identity of the caller are followed.


               Occasionally, we experience high call volumes due to unusual
               market activity or other events that may make it difficult for
               you to reach an Investor Service Representative by telephone. If
               you are unable to reach a representative by telephone, please
               consider sending written instructions, stopping by a Service
               Center, calling the Janus XpressLine or visiting our Web site.


               TEMPORARY SUSPENSION OF SERVICES

               The Fund or its agents may, in case of emergency, temporarily
               suspend telephone transactions and other shareholder services.

               ADDRESS CHANGES

               To change the address on your account, call 1-800-525-3713 or
               send a written request signed by the shareholder(s) of record.
               Include the name of your Fund, the account number(s), the name(s)
               on the account and both the old and new addresses. Certain
               options may be suspended for 10 days following an address change
               unless a signature guarantee is provided.

                                                        Shareholder's manual  25
<PAGE>

               REGISTRATION CHANGES

               To change the name on an account, the shares are generally
               transferred to a new account. In some cases, legal documentation
               may be required. For further instructions, please call an
               Investor Service Representative.

               STATEMENTS AND REPORTS

               Investors will receive quarterly confirmations of all
               transactions. Quarterly statements for all investors are
               available on our Web site. You may make an election on our Web
               site to discontinue delivery of your paper statements. Dividend
               information will be distributed annually. In addition, the Fund
               will send you an immediate transaction confirmation statement
               after every non-systematic transaction.

               The Fund produces financial reports, which include a list of the
               Fund's portfolio holdings, semiannually and updates its
               prospectus annually. To reduce expenses, the Fund may choose to
               mail only one report or prospectus to your household, even if
               more than one person in the household has a Fund account. Please
               call 1-800-525-3713 if you would like to receive additional
               reports or prospectuses. The Fund reserves the right to charge a
               fee for additional statement requests.

MANAGEMENT OF THE FUND
- --------------------------------------------------------------------------------

INVESTMENT ADVISER

               Janus Capital Corporation, 100 Fillmore Street, Denver, Colorado
               80206-4928, is the investment adviser to the Fund and is
               responsible for the day-to-day management of its investment
               portfolio and other business affairs.

               Janus Capital began serving as investment adviser to Janus Fund
               in 1970 and currently serves as investment adviser to all of the
               Janus funds, acts as sub-adviser for a number of private-label
               mutual funds and provides separate account advisory services for
               institutional accounts.

               Janus Capital furnishes continuous advice and recommendations
               concerning the Fund's investments. Janus Capital also furnishes
               certain administrative, compliance and accounting services for
               the Fund, and may be reimbursed by the Fund for its costs in
               providing those services. In addition, Janus Capital employees
               serve as officers of the Trust and Janus Capital provides office
               space for the Fund and pays the salaries, fees and expenses of
               all Fund officers and those Trustees who are affiliated with
               Janus Capital.

               The Fund pays Janus Capital a management fee which is calculated
               daily and paid monthly. The advisory agreement with the Fund
               spells out the management fee and other expenses that the Fund
               must pay.


               The Fund incurs expenses not assumed by Janus Capital, including
               transfer agent and custodian fees and expenses, legal and
               auditing fees, printing and mailing costs of sending reports and
               other information to existing shareholders, and independent
               Trustees' fees and expenses. The Fund expects to pay Janus
               Capital a management fee equal to 0.65% of average daily net
               assets during its initial fiscal year.

               SIZE OF THE FUND


               The Fund may discontinue sales of its shares if management and
               the Trustees believe that continued sales may adversely affect
               the Fund's ability to achieve its investment objective. If sales
               of the Fund are discontinued, it is expected that existing
               shareholders of the Fund would be permitted to continue to
               purchase shares and to reinvest any dividends or capital gains
               distributions, absent highly unusual circumstances.


               DISTRIBUTION OF FUND

               The Fund is distributed by Janus Distributors, Inc., a member of
               the National Association of Securities Dealers, Inc. ("NASD"). To
               obtain information about NASD member firms and their associated

DISTRIBUTIONS AND TAXES
- --------------------------------------------------------------------------------

DISTRIBUTIONS

               To avoid taxation of the Fund, the Internal Revenue Code requires
               the Fund to distribute net income and any net capital gains
               realized on its investments annually. The Fund's income from
               dividends and interest and any net realized short-term gains are
               paid to shareholders as ordinary income dividends. Net realized
               long-term gains are paid to shareholders as capital gains
               distributions. Dividends and capital gains distributions are
               normally declared and paid in December.

               HOW DISTRIBUTIONS AFFECT THE FUND'S NAV

               Distributions are paid to shareholders as of the record date of
               the distribution of the Fund, regardless of how long the shares
               have been held. Dividends and capital gains awaiting distribution
               are included in the Fund's daily NAV. The share price of the Fund
               drops by the amount of the distribution, net of any subsequent
               market fluctuations. As an example, assume that on December 31,
               the Fund declared a dividend in the amount of $0.25 per share. If
               the Fund's share price was $10.00 on December 30, the Fund's
               share price on December 31 would be $9.75, barring market
               fluctuations. Shareholders should be aware that distributions
               from a taxable mutual fund are not value-enhancing and may create
               income tax obligations.

               "BUYING A DIVIDEND"

               If you purchase shares of the Fund just before the distribution,
               you will pay the full price for the shares and receive a portion
               of the purchase price back as a taxable distribution. This is
               referred to as "buying a dividend." In the above example, if you
               bought shares on December 30, you would have paid $10.00 per
               share. On December 31, the Fund would pay you $0.25 per share as
               a dividend and your shares would now be worth $9.75 per share.
               Unless your account is set up as a tax-deferred account,
               dividends paid to you would be included in your gross income for
               tax purposes, even though you may not have participated in the

               increase in NAV of the Fund, whether or not you reinvested the
               dividends.

DISTRIBUTION OPTIONS

               When you open an account, you must specify on your application
               how you want to receive your distributions. You may change your
               distribution option at any time by writing the Fund at one of the
               addresses on page 14 or calling 1-800-525-3713. The Fund offers
               the following options:

               1. REINVESTMENT OPTION. You may reinvest your income dividends
                  and capital gains distributions in additional shares. This
                  option is assigned automatically if no other choice is made.

               2. CASH OPTION. You may receive your income dividends and capital
                  gains distributions in cash.

               3. REINVEST AND CASH OPTION. You may receive either your income
                  dividends or capital gains distributions in cash and reinvest
                  the other in additional shares.

               4. REDIRECT OPTION. You may direct your dividends or capital
                  gains to purchase shares of another Janus fund.

               The Fund reserves the right to reinvest into your account
               undeliverable and uncashed dividend and distribution checks that
               remain outstanding for six months in shares of the Fund at the
               NAV next computed after the check is cancelled. Subsequent
               distributions may also be reinvested.

TAXES

               As with any investment, you should consider the tax consequences
               of investing in the Fund. Any time you sell or exchange shares of
               a Fund in a taxable account, it is considered a taxable event.
               Depending on the purchase price and the sale price, you may have
               a gain or loss on the transaction. Any tax liabilities generated
               by your transactions are your responsibility.

               The following discussion does not apply to tax-deferred accounts,
               nor is it a complete analysis of the federal tax implications of


                                                 Janus Orion Fund prospectus  31

               investing in the Fund. You may wish to consult your own tax
               adviser. Additionally, state or local taxes may apply to your
               investment, depending upon the laws of your state of residence.

               TAXES ON DISTRIBUTIONS

               Dividends and distributions by the Fund are subject to federal
               income tax, regardless of whether the distribution is made in
               cash or reinvested in additional shares of the Fund.
               Distributions may be taxable at different rates depending on the
               length of time the Fund holds a security. In certain states, a
               portion of the dividends and distributions (depending on the
               source of the Fund's income) may be exempt from state and local
               taxes. Information regarding the tax status of income dividends
               and capital gains distributions will be mailed to shareholders on
               or before January 31st of each year. Account tax information will
               also be sent to the IRS.

               TAXATION OF THE FUND

               Dividends, interest, and some capital gains received by the Fund
               on foreign securities may be subject to tax withholding or other
               foreign taxes. The Fund may from year to year make the election
               permitted under section 853 of the Internal Revenue Code to pass
               through such taxes to shareholders as a foreign tax credit. If
               such an election is not made, any foreign taxes paid or accrued
               will represent an expense to the Fund.

               The Fund does not expect to pay federal income or excise taxes
               because it intends to meet certain requirements of the Internal
               Revenue Code. It is important that the Fund meet these
               requirements so that any earnings on your investment will not be
               taxed twice.

GLOSSARY OF INVESTMENT TERMS
- --------------------------------------------------------------------------------

               This glossary provides a more detailed description of some of the
               types of securities and other instruments in which the Fund may
               invest. The Fund may invest in these instruments to the extent
               permitted by its investment objective and policies. The Fund is
               not limited by this discussion and may invest in any other types
               of instruments not precluded by the policies discussed elsewhere
               in this Prospectus. Please refer to the SAI for a more detailed
               discussion of certain instruments.

I. EQUITY AND DEBT SECURITIES

               BONDS are debt securities issued by a company, municipality,
               government or government agency. The issuer of a bond is required
               to pay the holder the amount of the loan (or par value of the
               bond) at a specified maturity and to make scheduled interest
               payments.

               COMMERCIAL PAPER is a short-term debt obligation with a maturity
               ranging from 1 to 270 days issued by banks, corporations and
               other borrowers to investors seeking to invest idle cash. The
               Fund may purchase commercial paper issued in private placements
               under Section 4(2) of the Securities Act of 1933.

               COMMON STOCKS are equity securities representing shares of
               ownership in a company, and usually carry voting rights and earns
               dividends. Unlike preferred stock, dividends on common stocks are
               not fixed but are declared at the discretion of the issuer's
               board of directors.

               CONVERTIBLE SECURITIES are preferred stocks or bonds that pay a
               fixed dividend or interest payment and are convertible into
               common stock at a specified price or conversion ratio.

               DEBT SECURITIES are securities representing money borrowed that
               must be repaid at a later date. Such securities have specific
               maturities and usually a specific rate of interest or an original
               purchase discount.

               DEPOSITARY RECEIPTS are receipts for shares of a foreign-based
               corporation that entitle the holder to dividends and capital
               gains


                                                 Janus Orion Fund prospectus  33

<PAGE>

               on the underlying security. Receipts include those issued by
               domestic banks (American Depositary Receipts), foreign banks
               (Global or European Depositary Receipts) and broker-dealers
               (depositary shares).

               FIXED-INCOME SECURITIES are securities that pay a specified rate
               of return. The term generally includes short- and long-term
               government, corporate and municipal obligations that pay a
               specified rate of interest or coupons for a specified period of
               time, and preferred stock, which pays fixed dividends. Coupon and
               dividend rates may be fixed for the life of the issue or, in the
               case of adjustable and floating rate securities, for a shorter
               period.

               HIGH-YIELD/HIGH-RISK BONDS are bonds that are rated below
               investment grade by the primary rating agencies (e.g., BB or
               lower by Standard & Poor's and Ba or lower by Moody's). Other
               terms commonly used to describe such bonds include "lower rated
               bonds," "noninvestment grade bonds" and "junk bonds."

               MORTGAGE- AND ASSET-BACKED SECURITIES are shares in a pool of
               mortgages or other debt. These securities are generally pass-
               through securities, which means that principal and interest
               payments on the underlying securities (less servicing fees) are
               passed through to shareholders on a pro rata basis. These
               securities involve prepayment risk, which is the risk that the
               underlying mortgages or other debt may be refinanced or paid off
               prior to their maturities during periods of declining interest
               rates. In that case, the portfolio managers may have to reinvest
               the proceeds from the securities at a lower rate. Potential
               market gains on a security subject to prepayment risk may be more
               limited than potential market gains on a comparable security that
               is not subject to prepayment risk.

               PASSIVE FOREIGN INVESTMENT COMPANIES (PFICS) are any foreign
               corporations which generate certain amounts of passive income or
               hold certain amounts of assets for the production of passive
               income. Passive income includes dividends, interest, royalties,
               rents and annuities. To avoid taxes and interest that the Fund
               must pay if these investments are profitable, the Fund may make


 34 Janus Orion Fund prospectus

<PAGE>

               various elections permitted by the tax laws. These elections
               could require that the Fund recognize taxable income, which in
               turn must be distributed, before the securities are sold and
               before cash is received to pay the distributions.

               PREFERRED STOCKS are equity securities that generally pay
               dividends at a specified rate and have preference over common
               stock in the payment of dividends and liquidation. Preferred
               stock generally does not carry voting rights.

               REPURCHASE AGREEMENTS involve the purchase of a security by the
               Fund and a simultaneous agreement by the seller (generally a bank
               or dealer) to repurchase the security from the Fund at a
               specified date or upon demand. This technique offers a method of
               earning income on idle cash. These securities involve the risk
               that the seller will fail to repurchase the security, as agreed.
               In that case, the Fund will bear the risk of market value
               fluctuations until the security can be sold and may encounter
               delays and incur costs in liquidating the security.

               REVERSE REPURCHASE AGREEMENTS involve the sale of a security by
               the Fund to another party (generally a bank or dealer) in return
               for cash and an agreement by the Fund to buy the security back at
               a specified price and time. This technique will be used primarily
               to provide cash to satisfy unusually heavy redemption requests,
               or for other temporary or emergency purposes.

               U.S. GOVERNMENT SECURITIES include direct obligations of the U.S.
               government that are supported by its full faith and credit.
               Treasury bills have initial maturities of less than one year,
               Treasury notes have initial maturities of one to ten years and
               Treasury bonds may be issued with any maturity but generally have
               maturities of at least ten years. U.S. government securities also
               include indirect obligations of the U.S. government that are
               issued by federal agencies and government sponsored entities.
               Unlike Treasury securities, agency securities generally are not
               backed by the full faith and credit of the U.S. government. Some
               agency securities are supported by the right of the issuer to
               borrow from the Treasury, others are supported by the
               discretionary authority


                                                 Janus Orion Fund prospectus  35

<PAGE>

               of the U.S. government to purchase the agency's obligations and
               others are supported only by the credit of the sponsoring agency.

               WARRANTS are securities, typically issued with preferred stocks
               or bonds, that give the holder the right to buy a proportionate
               amount of common stock at a specified price, usually at a price
               that is higher than the market price at the time of issuance of
               the warrant. The right may last for a period of years or
               indefinitely.

               WHEN-ISSUED, DELAYED DELIVERY AND FORWARD TRANSACTIONS generally
               involve the purchase of a security with payment and delivery at
               some time in the future - i.e., beyond normal settlement. The
               Fund does not earn interest on such securities until settlement
               and bears the risk of market value fluctuations in between the
               purchase and settlement dates. New issues of stocks and bonds,
               private placements and U.S. government securities may be sold in
               this manner.

II. FUTURES, OPTIONS AND OTHER DERIVATIVES

               FORWARD CONTRACTS are contracts to purchase or sell a specified
               amount of a financial instrument for an agreed upon price at a
               specified time. Forward contracts are not currently exchange
               traded and are typically negotiated on an individual basis. The
               Fund may enter into forward currency contracts to hedge against
               declines in the value of securities denominated in, or whose
               value is tied to, a currency other than the U.S. dollar or to
               reduce the impact of currency appreciation on purchases of such
               securities. It may also enter into forward contracts to purchase
               or sell securities or other financial indices.

               FUTURES CONTRACTS are contracts that obligate the buyer to
               receive and the seller to deliver an instrument or money at a
               specified price on a specified date. The Fund may buy and sell
               futures contracts on foreign currencies, securities and financial
               indices including interest rates or an index of U.S. government,
               foreign government, equity or fixed-income securities. The Fund
               may also buy options on futures contracts. An option on a futures
               contract gives the buyer the right, but not the obligation, to
               buy or sell a


 36 Janus Orion Fund prospectus

<PAGE>

               futures contract at a specified price on or before a specified
               date. Futures contracts and options on futures are standardized
               and traded on designated exchanges.

               INDEXED/STRUCTURED SECURITIES are typically short- to
               intermediate-term debt securities whose value at maturity or
               interest rate is linked to currencies, interest rates, equity
               securities, indices, commodity prices or other financial
               indicators. Such securities may be positively or negatively
               indexed (i.e., their value may increase or decrease if the
               reference index or instrument appreciates). Indexed/structured
               securities may have return characteristics similar to direct
               investments in the underlying instrument and may be more volatile
               than the underlying instrument. The Fund bears the market risk of
               an investment in the underlying instrument, as well as the credit
               risk of the issuer.

               OPTIONS are the right, but not the obligation, to buy or sell a
               specified amount of securities or other assets on or before a
               fixed date at a predetermined price. The Fund may purchase and
               write put and call options on securities, securities indices and
               foreign currencies.

CLASSIFICATION, INVESTMENT POLICIES

AND RESTRICTIONS, AND INVESTMENT
STRATEGIES AND RISKS
- --------------------------------------------------------------------------------

CLASSIFICATION

               The Fund is a series of the Trust, an open-end, management
               investment company. The Investment Company Act of 1940 ("1940
               Act") classifies mutual funds as either diversified or
               nondiversified, and the Fund is a nondiversified fund. The Fund
               reserves the right to become a diversified fund by limiting the
               investments in which more than 5% of its total assets are
               invested.


INVESTMENT POLICIES AND RESTRICTIONS


               The Fund is subject to certain fundamental policies and
               restrictions that may not be changed without shareholder
               approval. Shareholder approval means approval by the lesser of
               (i) more than 50% of the outstanding voting securities of the
               Trust (or the Fund if a matter affects just the Fund), or (ii)
               67% or more of the voting securities present at a meeting if the
               holders of more than 50% of the outstanding voting securities of
               the Trust (or the Fund) are present or represented by proxy. As
               fundamental policies, the Fund may not:

               (1) Own more than 10% of the outstanding voting securities of any
               one issuer and, as to fifty percent (50%) of the value of its
               total assets, purchase the securities of any one issuer (except
               cash items and "government securities" as defined under the 1940
               Act), if immediately after and as a result of such purchase, the
               value of the holdings of the Fund in the securities of such
               issuer exceeds 5% of the value of the Fund's total assets. With
               respect to the other 50% of the value of its total assets, the
               Fund may invest in the securities of as few as two issuers.

               (2) Invest 25% or more of the value of its total assets in any
               particular industry (other than U.S. government securities).

               (3) Invest directly in real estate or interests in real estate;
               however, the Fund may own debt or equity securities issued by
               companies engaged in those businesses.

               (4) Purchase or sell physical commodities other than foreign
               currencies unless acquired as a result of ownership of securities

               (but this limitation shall not prevent the Fund from purchasing
               or selling options, futures, swaps and forward contracts or from
               investing in securities or other instruments backed by physical
               commodities).

               (5) Lend any security or make any other loan if, as a result,
               more than 25% of its total assets would be lent to other parties
               (but this limitation does not apply to purchases of commercial
               paper, debt securities or repurchase agreements).

               (6) Act as an underwriter of securities issued by others, except
               to the extent that the Fund may be deemed an underwriter in
               connection with the disposition of portfolio securities of the
               Fund.

               As a fundamental policy, the Fund may, notwithstanding any other
               investment policy or limitation (whether or not fundamental),
               invest all of its assets in the securities of a single open-end
               management investment company with substantially the same
               fundamental investment objective, policies and limitations as the
               Fund.

               The Trustees have adopted additional investment restrictions for
               the Fund. These restrictions are operating policies of the Fund
               and may be changed by the Trustees without shareholder approval.
               The additional investment restrictions adopted by the Trustees to
               date include the following:

               (a) The Fund will not (i) enter into any futures contracts and
               related options for purposes other than bona fide hedging
               transactions within the meaning of Commodity Futures Trading
               Commission ("CFTC") regulations if the aggregate initial margin
               and premiums required to establish positions in futures contracts
               and related options that do not fall within the definition of
               bona fide hedging transactions will exceed 5% of the fair market
               value of the Fund's net assets, after taking into account
               unrealized profits and unrealized losses on any such contracts it
               has entered into; and (ii) enter into any futures contracts if
               the aggregate amount of the Fund's commitments under outstanding
               futures

                                                                               3
<PAGE>

               contracts positions would exceed the market value of its total
               assets.

               (b) The Fund does not currently intend to sell securities short,
               unless it owns or has the right to obtain securities equivalent
               in kind and amount to the securities sold short without the
               payment of any additional consideration therefor, and provided
               that transactions in futures, options, swaps and forward
               contracts are not deemed to constitute selling securities short.

               (c) The Fund does not currently intend to purchase securities on
               margin, except that the Fund may obtain such short-term credits
               as are necessary for the clearance of transactions, and provided
               that margin payments and other deposits in connection with
               transactions in futures, options, swaps and forward contracts
               shall not be deemed to constitute purchasing securities on
               margin.

               (d) The Fund may not mortgage or pledge any securities owned or
               held by the Fund in amounts that exceed, in the aggregate, 15% of
               the Fund's net asset value, provided that this limitation does
               not apply to reverse repurchase agreements, deposits of assets to
               margin, guarantee positions in futures, options, swaps or forward
               contracts, or the segregation of assets in connection with such
               contracts.

               (e) The Fund may borrow money for temporary or emergency purposes
               (not for leveraging or investment) in an amount not exceeding 25%
               of the value of its total assets (including the amount borrowed)
               less liabilities (other than borrowings). If borrowings exceed
               25% of the value of the Fund's total assets by reason of a
               decline in net assets, the Fund will reduce its borrowings within
               three business days to the extent necessary to comply with the
               25% limitation. This policy shall not prohibit reverse repurchase
               agreements, deposits of assets to margin or guarantee positions
               in futures, options, swaps or forward contracts, or the
               segregation of assets in connection with such contracts.

               (f) The Fund does not currently intend to purchase any security
               or enter into a repurchase agreement if, as a result, more than
               15% of its net assets would be invested in repurchase agreements
               not entitling the holder to payment of principal and interest
               within seven days and in securities that are illiquid by virtue
               of legal or contractual restrictions on resale or the absence of
               a readily available market. The Trustees, or the Fund's
               investment adviser acting pursuant to authority delegated by the
               Trustees, may determine that a readily available market exists
               for securities eligible for resale pursuant to Rule 144A under
               the Securities Act of 1933 ("Rule 144A Securities"), or any
               successor to such rule, Section 4(2) commercial paper and
               municipal lease obligations. Accordingly, such securities may not
               be subject to the foregoing limitation.

               (g) The Fund may not invest in companies for the purpose of
               exercising control of management.

               Under the terms of an exemptive order received from the
               Securities and Exchange Commission ("SEC") the Fund may borrow
               money from or lend money to other funds that permit such
               transactions and for which Janus Capital serves as investment
               adviser. All such borrowing and lending will be subject to the
               above limits. The Fund will borrow money through the program only
               when the costs are equal to or lower than the cost of bank loans.
               Interfund loans and borrowings normally extend overnight, but can
               have maximum duration of seven days. The Fund will lend through
               the program only when the returns are higher than those available
               from other short-term instruments (such as repurchase
               agreements). The Fund may have to borrow from a bank at a higher
               interest rate if an interfund loan is called or not renewed. Any
               delay in repayment to a lending Fund could result in a lost
               investment opportunity or additional borrowing costs.

               For the purposes of the Fund's policies on investing in
               particular industries, the Fund will rely primarily on industry
               or industry group classifications published by Bloomberg L.P. To
               the extent that Bloomberg L.P. industry classifications are so
               broad that the

                                                                               5
<PAGE>

               primary economic characteristics in a single industry are
               materially different, the Fund may further classify issuers in
               accordance with industry classifications as published by the SEC.

INVESTMENT STRATEGIES AND RISKS

Cash Position

               As discussed in the Prospectus, when the Fund's portfolio manager
               believes that market conditions are unfavorable for profitable
               investing, or when he is otherwise unable to locate attractive
               investment opportunities, the Fund's investment in cash and
               similar investments may increase. Securities that the Fund may
               invest in as a means of receiving a return on idle cash include
               commercial paper, certificates of deposit, repurchase agreements
               or other short-term debt obligations. The Fund may also invest in
               money market funds, including funds managed by Janus Capital.
               (See "Investment Company Securities" on page 13).

Illiquid Investments

               The Fund may invest up to 15% of its net assets in illiquid
               investments (i.e., securities that are not readily marketable).
               The Trustees have authorized Janus Capital to make liquidity
               determinations with respect to certain securities, including Rule
               144A Securities, commercial paper and municipal lease obligations
               purchased by the Fund. Under the guidelines established by the
               Trustees, Janus Capital will consider the following factors: 1)
               the frequency of trades and quoted prices for the obligation; 2)
               the number of dealers willing to purchase or sell the security
               and the number of other potential purchasers; 3) the willingness
               of dealers to undertake to make a market in the security; and 4)
               the nature of the security and the nature of marketplace trades,
               including the time needed to dispose of the security, the method
               of soliciting offers and the mechanics of the transfer. In the
               case of commercial paper, Janus Capital will also consider
               whether the paper is traded flat or in default as to principal
               and interest and any ratings of the

 6
<PAGE>

               paper by a Nationally Recognized Statistical Rating Organization
               ("NRSRO"). A foreign security that may be freely traded on or
               through the facilities of an offshore exchange or other
               established offshore securities market is not deemed to be a
               restricted security subject to these procedures.

               If illiquid securities exceed 15% of the Fund's net assets after
               the time of purchase the Fund will take steps to reduce in an
               orderly fashion its holdings of illiquid securities. Because
               illiquid securities may not be readily marketable, the portfolio
               manager may not be able to dispose of them in a timely manner. As
               a result, the Fund may be forced to hold illiquid securities
               while their price depreciates. Depreciation in the price of
               illiquid securities may cause the net asset value of the Fund to
               decline.

Securities Lending

               The Fund may lend securities to qualified parties (typically
               brokers or other financial institutions) who need to borrow
               securities in order to complete certain transactions such as
               covering short sales, avoiding failures to deliver securities or
               completing arbitrage activities. The Fund may seek to earn
               additional income through securities lending. Since there is the
               risk of delay in recovering a loaned security or the risk of loss
               in collateral rights if the borrower fails financially,
               securities lending will only be made to parties that Janus
               Capital deems creditworthy and in good standing. In addition,
               such loans will only be made if Janus Capital believes the
               benefit from granting such loans justifies the risk. The Fund
               will not have the right to vote on securities while they are
               being lent, but it will call a loan in anticipation of any
               important vote. All loans will be continuously secured by
               collateral which consists of cash, U.S. government securities,
               letters of credit and such other collateral permitted by the
               Securities and Exchange Commission and policies approved by the
               Trustees. Cash collateral may be invested in money market funds
               advised by Janus to the extent consistent with exemptive relief
               obtained from the SEC.

                                                                               7

Foreign Securities

               The Fund may invest without limit in foreign securities either
               indirectly (e.g., depositary receipts) or directly in foreign
               markets. Investments in foreign securities, including those of
               foreign governments, may involve greater risks than investing in
               domestic securities, because the Fund's performance may depend on
               issues other than the performance of a particular company. These
               issues include:

               - CURRENCY RISK. As long as the Fund holds a foreign security,
                 its value will be affected by the value of the local currency
                 relative to the U.S. dollar. When the Fund sells a foreign
                 denominated security, its value may be worth less in U.S.
                 dollars even if the security increases in value in its home
                 country. U.S. dollar denominated securities of foreign issuers
                 may also be affected by currency risk.

               - POLITICAL AND ECONOMIC RISK. Foreign investments may be subject
                 to heightened political and economic risks, particularly in
                 emerging markets which may have relatively unstable
                 governments, immature economic structures, national policies
                 restricting investments by foreigners, different legal systems,
                 and economies based on only a few industries. In some
                 countries, there is the risk that the government may take over
                 the assets or operations of a company or that the government
                 may impose taxes or limits on the removal of a Fund's assets
                 from that country.

               - REGULATORY RISK. There may be less government supervision of
                 foreign markets. As a result, foreign issuers may not be
                 subject to the uniform accounting, auditing and financial
                 reporting standards and practices applicable to domestic
                 issuers and there may be less publicly available information
                 about foreign issuers.

               - MARKET RISK. Foreign securities markets, particularly those of
                 emerging market countries, may be less liquid and more volatile
                 than domestic markets. Certain markets may require payment for
                 securities before delivery and delays may be encountered in

 8
<PAGE>

                 settling securities transactions. In some foreign markets,
                 there may not be protection against failure by other parties to
                 complete transactions.

               - TRANSACTION COSTS. Costs of buying, selling and holding foreign
                 securities, including brokerage, tax and custody costs, may be
                 higher than those involved in domestic transactions.

Short Sales

               The Fund may engage in "short sales against the box." This
               technique involves selling either a security that the Fund owns,
               or a security equivalent in kind and amount to the security sold
               short that the Fund has the right to obtain, for delivery at a
               specified date in the future. The Fund may enter into a short
               sale against the box to hedge against anticipated declines in the
               market price of portfolio securities. If the value of the
               securities sold short increases prior to the scheduled delivery
               date, the Fund loses the opportunity to participate in the gain.

Zero Coupon, Step Coupon and Pay-In-Kind Securities

               The Fund may invest up to 10% of its assets in zero coupon, pay-
               in-kind and step coupon securities. Zero coupon bonds are issued
               and traded at a discount from their face value. They do not
               entitle the holder to any periodic payment of interest prior to
               maturity. Step coupon bonds trade at a discount from their face
               value and pay coupon interest. The coupon rate is low for an
               initial period and then increases to a higher coupon rate
               thereafter. The discount from the face amount or par value
               depends on the time remaining until cash payments begin,
               prevailing interest rates, liquidity of the security and the
               perceived credit quality of the issuer. Pay-in-kind bonds
               normally give the issuer an option to pay cash at a coupon
               payment date or give the holder of the security a similar bond
               with the same coupon rate and a face value equal to the amount of
               the coupon payment that would have been made.

                                                                               9
<PAGE>

               Current federal income tax law requires holders of zero coupon
               and step coupon securities to report the portion of the original
               issue discount on such securities that accrues during a given
               year as interest income, even though the holders receive no cash
               payments of interest during the year. In order to qualify as a
               "regulated investment company" under the Internal Revenue Code of
               1986 and the regulations thereunder (the "Code"), the Fund must
               distribute its investment company taxable income, including the
               original issue discount accrued on zero coupon or step coupon
               bonds. Because the Fund will not receive cash payments on a
               current basis in respect of accrued original issue discount on
               zero coupon bonds or step coupon bonds during the period before
               interest payments begin, in some years the Fund may have to
               distribute cash obtained from other sources in order to satisfy
               the distribution requirements under the Code. The Fund might
               obtain such cash from selling other portfolio holdings which
               might cause the Fund to incur capital gains or losses on the
               sale. Additionally, these actions are likely to reduce the assets
               to which Fund expenses could be allocated and to reduce the rate
               of return for the Fund. In some circumstances, such sales might
               be necessary in order to satisfy cash distribution requirements
               even though investment considerations might otherwise make it
               undesirable for the Fund to sell the securities at the time.

               Generally, the market prices of zero coupon, step coupon and
               pay-in-kind securities are more volatile than the prices of
               securities that pay interest periodically and in cash and are
               likely to respond to changes in interest rates to a greater
               degree than other types of debt securities having similar
               maturities and credit quality.

Pass-Through Securities

               The Fund may invest in various types of pass-through securities,
               such as mortgage-backed securities, asset-backed securities and
               participation interests. A pass-through security is a share or
               certificate of interest in a pool of debt obligations that have
               been repackaged by an intermediary, such as a bank or
               broker-dealer.

 10
<PAGE>

               The purchaser of a pass-through security receives an undivided
               interest in the underlying pool of securities. The issuers of the
               underlying securities make interest and principal payments to the
               intermediary which are passed through to purchasers, such as the
               Fund. The most common type of pass-through securities are
               mortgage-backed securities. Government National Mortgage
               Association ("GNMA") Certificates are mortgage-backed securities
               that evidence an undivided interest in a pool of mortgage loans.
               GNMA Certificates differ from bonds in that principal is paid
               back monthly by the borrowers over the term of the loan rather
               than returned in a lump sum at maturity. The Fund will generally
               purchase "modified pass-through" GNMA Certificates, which entitle
               the holder to receive a share of all interest and principal
               payments paid and owned on the mortgage pool, net of fees paid to
               the "issuer" and GNMA, regardless of whether or not the mortgagor
               actually makes the payment. GNMA Certificates are backed as to
               the timely payment of principal and interest by the full faith
               and credit of the U.S. government.

               The Federal Home Loan Mortgage Corporation ("FHLMC") issues two
               types of mortgage pass-through securities: mortgage participation
               certificates ("PCs") and guaranteed mortgage certificates
               ("GMCs"). PCs resemble GNMA Certificates in that each PC
               represents a pro rata share of all interest and principal
               payments made and owned on the underlying pool. FHLMC guarantees
               timely payments of interest on PCs and the full return of
               principal. GMCs also represent a pro rata interest in a pool of
               mortgages. However, these instruments pay interest semiannually
               and return principal once a year in guaranteed minimum payments.
               This type of security is guaranteed by FHLMC as to timely payment
               of principal and interest but it is not guaranteed by the full
               faith and credit of the U.S. government.

               The Federal National Mortgage Association ("FNMA") issues
               guaranteed mortgage pass-through certificates ("FNMA
               Certificates"). FNMA Certificates resemble GNMA Certificates in
               that each FNMA Certificate represents a pro rata share of all
               interest

                                                                              11
<PAGE>

               and principal payments made and owned on the underlying pool.
               This type of security is guaranteed by FNMA as to timely payment
               of principal and interest but it is not guaranteed by the full
               faith and credit of the U.S. government.

               Except for GMCs, each of the mortgage-backed securities described
               above is characterized by monthly payments to the holder,
               reflecting the monthly payments made by the borrowers who
               received the underlying mortgage loans. The payments to the
               security holders (such as the Fund), like the payments on the
               underlying loans, represent both principal and interest. Although
               the underlying mortgage loans are for specified periods of time,
               such as 20 or 30 years, the borrowers can, and typically do, pay
               them off sooner. Thus, the security holders frequently receive
               prepayments of principal in addition to the principal that is
               part of the regular monthly payments. The Fund's portfolio
               manager will consider estimated prepayment rates in calculating
               the average weighted maturity of the Fund. A borrower is more
               likely to prepay a mortgage that bears a relatively high rate of
               interest. This means that in times of declining interest rates,
               higher yielding mortgage-backed securities held by the Fund might
               be converted to cash and the Fund will be forced to accept lower
               interest rates when that cash is used to purchase additional
               securities in the mortgage-backed securities sector or in other
               investment sectors. Additionally, prepayments during such periods
               will limit the Fund's ability to participate in as large a market
               gain as may be experienced with a comparable security not subject
               to prepayment.

               Asset-backed securities represent interests in pools of consumer
               loans and are backed by paper or accounts receivables originated
               by banks, credit card companies or other providers of credit.
               Generally, the originating bank or credit provider is neither the
               obligor nor the guarantor of the security, and interest and
               principal payments ultimately depend upon payment of the
               underlying loans by individuals. Tax-exempt asset-backed
               securities include units of beneficial interests in pools of
               purchase

               contracts, financing leases, and sales agreements that may be
               created when a municipality enters into an installment purchase
               contract or lease with a vendor. Such securities may be secured
               by the assets purchased or leased by the municipality; however,
               if the municipality stops making payments, there generally will
               be no recourse against the vendor. These obligations are likely
               to involve unscheduled prepayments of principal.

Investment Company Securities

               From time to time, the Fund may invest in securities of other
               investment companies, subject to the provisions of Section
               12(d)(1) of the 1940 Act. The Fund may invest in securities of
               money market funds managed by Janus Capital in excess of the
               limitations of Section 12(d)(1) under the terms of an SEC
               exemptive order obtained by Janus Capital and the Janus funds.

Depositary Receipts

               The Fund may invest in sponsored and unsponsored American
               Depositary Receipts ("ADRs"), which are receipts issued by an
               American bank or trust company evidencing ownership of underlying
               securities issued by a foreign issuer. ADRs, in registered form,
               are designed for use in U.S. securities markets. Unsponsored ADRs
               may be created without the participation of the foreign issuer.
               Holders of these ADRs generally bear all the costs of the ADR
               facility, whereas foreign issuers typically bear certain costs in
               a sponsored ADR. The bank or trust company depositary of an
               unsponsored ADR may be under no obligation to distribute
               shareholder communications received from the foreign issuer or to
               pass through voting rights. The Fund may also invest in European
               Depositary Receipts ("EDRs"), Global Depositary Receipts ("GDRs")
               and in other similar instruments representing securities of
               foreign companies. EDRs and GDRs are securities that are
               typically issued by foreign banks or foreign trust companies,
               although U.S. banks or U.S. trust companies may issue them. EDRs
               and GDRs are similar to the arrangements of ADRs. EDRs,

                                                                              13
<PAGE>

               in bearer form, are designed for use in European securities
               markets.

               Depositary Receipts are generally subject to the same sort of
               risks as direct investments in a foreign country, such as,
               currency risk, political and economic risk, and market risk,
               because their values depend on the performance of a foreign
               security denominated in its home currency. The risks of foreign
               investing are addressed in some detail in the Fund's prospectus.

Municipal Obligations

               The Fund may invest in municipal obligations issued by states,
               territories and possessions of the United States and the District
               of Columbia. The value of municipal obligations can be affected
               by changes in their actual or perceived credit quality. The
               credit quality of municipal obligations can be affected by, among
               other things the financial condition of the issuer or guarantor,
               the issuer's future borrowing plans and sources of revenue, the
               economic feasibility of the revenue bond project or general
               borrowing purpose, political or economic developments in the
               region where the security is issued, and the liquidity of the
               security. Because municipal securities are generally traded over-
               the-counter, the liquidity of a particular issue often depends on
               the willingness of dealers to make a market in the security. The
               liquidity of some municipal obligations may be enhanced by demand
               features, which would enable the Fund to demand payment on short
               notice from the issuer or a financial intermediary.

Other Income-Producing Securities

               Other types of income producing securities that the Fund may
               purchase include, but are not limited to, the following types of
               securities:

               VARIABLE AND FLOATING RATE OBLIGATIONS. These types of securities
               have variable or floating rates of interest and, under certain
               limited circumstances, may have varying principal amounts. These

 14
<PAGE>

               securities pay interest at rates that are adjusted periodically
               according to a specified formula, usually with reference to some
               interest rate index or market interest rate. The floating rate
               tends to decrease the security's price sensitivity to changes in
               interest rates. These types of securities have variable or
               floating rates of interest and, under certain limited
               circumstances, may have varying principal amounts. Variable and
               floating rate securities pay interest at rates that are adjusted
               periodically according to a specified formula, usually with
               reference to some interest rate index or market interest rate
               (the "underlying index"). See also "Inverse Floaters."

               In order to most effectively use these investments, the portfolio
               manager must correctly assess probable movements in interest
               rates. This involves different skills than those used to select
               most portfolio securities. If the portfolio manager incorrectly
               forecasts such movements, the Fund could be adversely affected by
               the use of variable or floating rate obligations.

               STANDBY COMMITMENTS. These instruments, which are similar to a
               put, give the Fund the option to obligate a broker, dealer or
               bank to repurchase a security held by the Fund at a specified
               price.

               TENDER OPTION BONDS. Tender option bonds are generally long-term
               securities that are coupled with the option to tender the
               securities to a bank, broker-dealer or other financial
               institution at periodic intervals and receive the face value of
               the bond. This type of security is commonly used as a means of
               enhancing the security's liquidity.

               INVERSE FLOATERS. Inverse floaters are debt instruments whose
               interest bears an inverse relationship to the interest rate on
               another security. The Fund will not invest more than 5% of its
               assets in inverse floaters. Similar to variable and floating rate
               obligations, effective use of inverse floaters requires skills
               different from those needed to select most portfolio securities.
               If movements in interest rates are incorrectly anticipated, the
               Fund could

                                                                              15
<PAGE>

               lose money or its NAV could decline by the use of inverse
               floaters.

               STRIP BONDS. Strip bonds are debt securities that are stripped of
               their interest (usually by a financial intermediary) after the
               securities are issued. The market value of these securities
               generally fluctuates more in response to changes in interest
               rates than interest-paying securities of comparable maturity.

               The Fund will purchase standby commitments, tender option bonds
               and instruments with demand features primarily for the purpose of
               increasing the liquidity of its portfolio.

High-Yield/High-Risk Bonds

               The Fund intends to invest less than 35% of its net assets in
               bonds that are rated below investment grade (e.g., bonds rated BB
               or lower by Standard & Poor's Ratings Services or Ba or lower by
               Moody's Investors Service, Inc.). Lower rated bonds involve a
               higher degree of credit risk, which is the risk that the issuer
               will not make interest or principal payments when due. In the
               event of an unanticipated default, the Fund would experience a
               reduction in its income, and could expect a decline in the market
               value of the bonds so affected.

               The Fund may also invest in unrated debt bonds of foreign and
               domestic issuers. Unrated bonds, while not necessarily of lower
               quality than rated bonds, may not have as broad a market.
               Sovereign debt of foreign governments is generally rated by
               country. Because these ratings do not take into account
               individual factors relevant to each issue and may not be updated
               regularly, Janus Capital may treat such securities as unrated
               debt. Because of the size and perceived demand of the issue,
               among other factors, certain municipalities may not incur the
               costs of obtaining a rating. The Fund's portfolio manager will
               analyze the creditworthiness of the issuer, as well as any
               financial institution or other party responsible for payments on
               the bond, in determining whether to purchase unrated municipal
               bonds. Unrated bonds will

 16
<PAGE>

               be included in the 35% limit unless the portfolio manager deems
               such securities to be the equivalent of investment grade bonds.

               Subject to the above limits, the Fund may purchase defaulted
               securities only when its portfolio manager believes, based upon
               his analysis of the financial condition, results of operations
               and economic outlook of an issuer, that there is potential for
               resumption of income payments and that the securities offer an
               unusual opportunity for capital appreciation. Notwithstanding the
               portfolio manager's belief about the resumption of income,
               however, the purchase of any security on which payment of
               interest or dividends is suspended involves a high degree of
               risk. Such risk includes, among other things, the following:

               FINANCIAL AND MARKET RISKS. Investments in securities that are in
               default involve a high degree of financial and market risks that
               can result in substantial or, at times, even total losses.
               Issuers of defaulted securities may have substantial capital
               needs and may become involved in bankruptcy or reorganization
               proceedings. Among the problems involved in investments in such
               issuers is the fact that it may be difficult to obtain
               information about the condition of such issuers. The market
               prices of such securities also are subject to abrupt and erratic
               movements and above average price volatility, and the spread
               between the bid and asked prices of such securities may be
               greater than normally expected.

               DISPOSITION OF PORTFOLIO SECURITIES. Although the Fund generally
               will purchase securities for which its portfolio manager expects
               an active market to be maintained, defaulted securities may be
               less actively traded than other securities and it may be
               difficult to dispose of substantial holdings of such securities
               at prevailing market prices. The Fund will limit holdings of any
               such securities to amounts that the portfolio manager believes
               could be readily sold, and holdings of such securities would, in
               any event, be limited so as not to limit the Fund's ability to
               readily dispose of securities to meet redemptions.

                                                                              17
<PAGE>

               OTHER. Defaulted securities require active monitoring and may, at
               times, require participation in bankruptcy or receivership
               proceedings on behalf of the Fund.

Repurchase and Reverse Repurchase Agreements

               In a repurchase agreement, the Fund purchases a security and
               simultaneously commits to resell that security to the seller at
               an agreed upon price on an agreed upon date within a number of
               days (usually not more than seven) from the date of purchase. The
               resale price consists of the purchase price plus an agreed upon
               incremental amount that is unrelated to the coupon rate or
               maturity of the purchased security. A repurchase agreement
               involves the obligation of the seller to pay the agreed upon
               price, which obligation is in effect secured by the value (at
               least equal to the amount of the agreed upon resale price and
               marked-to-market daily) of the underlying security or
               "collateral." A risk associated with repurchase agreements is the
               failure of the seller to repurchase the securities as agreed,
               which may cause the Fund to suffer a loss if the market value of
               such securities declines before they can be liquidated on the
               open market. In the event of bankruptcy or insolvency of the
               seller, the Fund may encounter delays and incur costs in
               liquidating the underlying security. Repurchase agreements that
               mature in more than seven days are subject to the 15% limit on
               illiquid investments. While it is possible to eliminate all risks
               from these transactions, it is the policy of the Fund to limit
               repurchase agreements to those parties whose creditworthiness has
               been reviewed and found satisfactory by Janus Capital.

               The Fund may use reverse repurchase agreements to obtain cash to
               satisfy unusually heavy redemption requests or for other
               temporary or emergency purposes without the necessity of selling
               portfolio securities or to earn additional income on portfolio
               securities, such as Treasury bills or notes. In a reverse
               repurchase agreement, the Fund sells a portfolio security to
               another party, such as a bank or broker-dealer, in return for
               cash and agrees to repurchase the instrument at a particular
               price and time. While a

 18
<PAGE>

               reverse repurchase agreement is outstanding, the Fund will
               maintain cash and appropriate liquid assets in a segregated
               custodial account to cover its obligation under the agreement.
               The Fund will enter into reverse repurchase agreements only with
               parties that Janus Capital deems creditworthy. Using reverse
               repurchase agreements to earn additional income involves the risk
               that the interest earned on the invested proceeds is less than
               the expense of the reverse repurchase agreement transaction. This
               technique may also have a leveraging effect on the Fund's
               portfolio, although the Fund's intent to segregate assets in the
               amount of the reverse repurchase agreement minimizes this effect.

Futures, Options and Other Derivative Instruments

               FUTURES CONTRACTS. The Fund may enter into contracts for the
               purchase or sale for future delivery of fixed-income securities,
               foreign currencies or contracts based on financial indices,
               including indices of U.S. government securities, foreign
               government securities, equity or fixed-income securities. U.S.
               futures contracts are traded on exchanges which have been
               designated "contract markets" by the CFTC and must be executed
               through a futures commission merchant ("FCM"), or brokerage firm,
               which is a member of the relevant contract market. Through their
               clearing corporations, the exchanges guarantee performance of the
               contracts as between the clearing members of the exchange.

               The buyer or seller of a futures contract is not required to
               deliver or pay for the underlying instrument unless the contract
               is held until the delivery date. However, both the buyer and
               seller are required to deposit "initial margin" for the benefit
               of the FCM when the contract is entered into. Initial margin
               deposits are equal to a percentage of the contract's value, as
               set by the exchange on which the contract is traded, and may be
               maintained in cash or certain other liquid assets by the Fund's
               custodian for the benefit of the FCM. Initial margin payments are
               similar to good faith deposits or performance bonds. Unlike
               margin extended by a securities broker, initial margin payments
               do not constitute purchasing securities on margin for purposes of
               the Fund's

                                                                              19

               investment limitations. If the value of either party's position
               declines, that party will be required to make additional
               "variation margin" payments for the benefit of the FCM to settle
               the change in value on a daily basis. The party that has a gain
               may be entitled to receive all or a portion of this amount. In
               the event of the bankruptcy of the FCM that holds margin on
               behalf of the Fund, the Fund may be entitled to a return of
               margin owed to the Fund only in proportion to the amount received
               by the FCM's other customers. Janus Capital will attempt to
               minimize the risk by careful monitoring of the creditworthiness
               of the FCMs with which the Fund does business and by depositing
               margin payments in a segregated account with the Fund's
               custodian.

               The Fund intends to comply with guidelines of eligibility for
               exclusion from the definition of the term "commodity pool
               operator" adopted by the CFTC and the National Futures
               Association, which regulate trading in the futures markets. The
               Fund will use futures contracts and related options primarily for
               bona fide hedging purposes within the meaning of CFTC
               regulations. To the extent that the Fund holds positions in
               futures contracts and related options that do not fall within the
               definition of bona fide hedging transactions, the aggregate
               initial margin and premiums required to establish such positions
               will not exceed 5% of the fair market value of the Fund's net
               assets, after taking into account unrealized profits and
               unrealized losses on any such contracts it has entered into.

               Although the Fund will segregate cash and liquid assets in an
               amount sufficient to cover its open futures obligations, the
               segregated assets would be available to the Fund immediately upon
               closing out the futures position, while settlement of securities
               transactions could take several days. However, because the Fund's
               cash that may otherwise be invested would be held uninvested or
               invested in other liquid assets so long as the futures position
               remains open, the Fund's return could be diminished due to the
               opportunity losses of foregoing other potential investments.

               The Fund's primary purpose in entering into futures contracts is
               to protect the Fund from fluctuations in the value of securities
               or interest rates without actually buying or selling the
               underlying debt or equity security. For example, if the Fund
               anticipates an increase in the price of stocks, and it intends to
               purchase stocks at a later time, the Fund could enter into a
               futures contract to purchase a stock index as a temporary
               substitute for stock purchases. If an increase in the market
               occurs that influences the stock index as anticipated, the value
               of the futures contracts will increase, thereby serving as a
               hedge against the Fund not participating in a market advance.
               This technique is sometimes known as an anticipatory hedge. To
               the extent the Fund enters into futures contracts for this
               purpose, the segregated assets maintained to cover the Fund's
               obligations with respect to the futures contracts will consist of
               other liquid assets from its portfolio in an amount equal to the
               difference between the contract price and the aggregate value of
               the initial and variation margin payments made by the Fund with
               respect to the futures contracts. Conversely, if the Fund holds
               stocks and seeks to protect itself from a decrease in stock
               prices, the Fund might sell stock index futures contracts,
               thereby hoping to offset the potential decline in the value of
               its portfolio securities by a corresponding increase in the value
               of the futures contract position. The Fund could protect against
               a decline in stock prices by selling portfolio securities and
               investing in money market instruments, but the use of futures
               contracts enables it to maintain a defensive position without
               having to sell portfolio securities.

               If the Fund owns bonds and the portfolio manager expects interest
               rates to increase, the Fund may take a short position in interest
               rate futures contracts. Taking such a position would have much
               the same effect as the Fund selling bonds in its portfolio. If
               interest rates increase as anticipated, the value of the bonds
               would decline, but the value of the Fund's interest rate futures
               contract will increase, thereby keeping the net asset value of
               the Fund from declining as much as it may have otherwise. If, on
               the other hand,

                                                                              21
<PAGE>

               the portfolio manager expects interest rates to decline, the Fund
               may take a long position in interest rate futures contracts in
               anticipation of later closing out the futures position and
               purchasing bonds. Although the Fund can accomplish similar
               results by buying securities with long maturities and selling
               securities with short maturities, given the greater liquidity of
               the futures market than the cash market, it may be possible to
               accomplish the same result more easily and more quickly by using
               futures contracts as an investment tool to reduce risk.

               The ordinary spreads between prices in the cash and futures
               markets, due to differences in the nature of those markets, are
               subject to distortions. First, all participants in the futures
               market are subject to initial margin and variation margin
               requirements. Rather than meeting additional variation margin
               requirements, investors may close out futures contracts through
               offsetting transactions which could distort the normal price
               relationship between the cash and futures markets. Second, the
               liquidity of the futures market depends on participants entering
               into offsetting transactions rather than making or taking
               delivery of the instrument underlying a futures contract. To the
               extent participants decide to make or take delivery, liquidity in
               the futures market could be reduced and prices in the futures
               market distorted. Third, from the point of view of speculators,
               the margin deposit requirements in the futures market are less
               onerous than margin requirements in the securities market.
               Therefore, increased participation by speculators in the futures
               market may cause temporary price distortions. Due to the
               possibility of the foregoing distortions, a correct forecast of
               general price trends by the portfolio manager still may not
               result in a successful use of futures.

               Futures contracts entail risks. Although the Fund believes that
               use of such contracts will benefit the Fund, the Fund's overall
               performance could be worse than if the Fund had not entered into
               futures contracts if the portfolio manager's investment judgement
               proves incorrect. For example, if the Fund has hedged

 22
<PAGE>

               against the effects of a possible decrease in prices of
               securities held in its portfolio and prices increase instead, the
               Fund will lose part or all of the benefit of the increased value
               of these securities because of offsetting losses in its futures
               positions. In addition, if the Fund has insufficient cash, it may
               have to sell securities from its portfolio to meet daily
               variation margin requirements. Those sales may be, but will not
               necessarily be, at increased prices which reflect the rising
               market and may occur at a time when the sales are disadvantageous
               to the Fund.

               The prices of futures contracts depend primarily on the value of
               their underlying instruments. Because there are a limited number
               of types of futures contracts, it is possible that the
               standardized futures contracts available to the Fund will not
               match exactly the Fund's current or potential investments. The
               Fund may buy and sell futures contracts based on underlying
               instruments with different characteristics from the securities in
               which it typically invests - for example, by hedging investments
               in portfolio securities with a futures contract based on a broad
               index of securities - which involves a risk that the futures
               position will not correlate precisely with the performance of the
               Fund's investments.

               Futures prices can also diverge from the prices of their
               underlying instruments, even if the underlying instruments
               closely correlate with the Fund's investments. Futures prices are
               affected by factors such as current and anticipated short-term
               interest rates, changes in volatility of the underlying
               instruments and the time remaining until expiration of the
               contract. Those factors may affect securities prices differently
               from futures prices. Imperfect correlations between the Fund's
               investments and its futures positions also may result from
               differing levels of demand in the futures markets and the
               securities markets, from structural differences in how futures
               and securities are traded, and from imposition of daily price
               fluctuation limits for futures contracts. The Fund may buy or
               sell futures contracts with a greater or lesser value than the
               securities it wishes to hedge or is considering purchasing in
               order to attempt to compensate for differences in historical
               volatility

                                                                              23
<PAGE>

               between the futures contract and the securities, although this
               may not be successful in all cases. If price changes in the
               Fund's futures positions are poorly correlated with its other
               investments, its futures positions may fail to produce desired
               gains or result in losses that are not offset by the gains in the
               Fund's other investments.

               Because futures contracts are generally settled within a day from
               the date they are closed out, compared with a settlement period
               of three days for some types of securities, the futures markets
               can provide superior liquidity to the securities markets.
               Nevertheless, there is no assurance that a liquid secondary
               market will exist for any particular futures contract at any
               particular time. In addition, futures exchanges may establish
               daily price fluctuation limits for futures contracts and may halt
               trading if a contract's price moves upward or downward more than
               the limit in a given day. On volatile trading days when the price
               fluctuation limit is reached, it may be impossible for the Fund
               to enter into new positions or close out existing positions. If
               the secondary market for a futures contract is not liquid because
               of price fluctuation limits or otherwise, the Fund may not be
               able to promptly liquidate unfavorable futures positions and
               potentially could be required to continue to hold a futures
               position until the delivery date, regardless of changes in its
               value. As a result, the Fund's access to other assets held to
               cover its futures positions also could be impaired.

               OPTIONS ON FUTURES CONTRACTS. The Fund may buy and write put and
               call options on futures contracts. An option on a future gives
               the Fund the right (but not the obligation) to buy or sell a
               futures contract at a specified price on or before a specified
               date. The purchase of a call option on a futures contract is
               similar in some respects to the purchase of a call option on an
               individual security. Depending on the pricing of the option
               compared to either the price of the futures contract upon which
               it is based or the price of the underlying instrument, ownership
               of the option may or may not be less risky than ownership of the
               futures contract or the

 24
<PAGE>

               underlying instrument. As with the purchase of futures contracts,
               when the Fund is not fully invested it may buy a call option on a
               futures contract to hedge against a market advance.

               The writing of a call option on a futures contract constitutes a
               partial hedge against declining prices of the security or foreign
               currency which is deliverable under, or of the index comprising,
               the futures contract. If the future's price at the expiration of
               the option is below the exercise price, the Fund will retain the
               full amount of the option premium which provides a partial hedge
               against any decline that may have occurred in the Fund's
               portfolio holdings. The writing of a put option on a futures
               contract constitutes a partial hedge against increasing prices of
               the security or foreign currency which is deliverable under, or
               of the index comprising, the futures contract. If the futures'
               price at expiration of the option is higher than the exercise
               price, the Fund will retain the full amount of the option premium
               which provides a partial hedge against any increase in the price
               of securities which the Fund is considering buying. If a call or
               put option the Fund has written is exercised, the Fund will incur
               a loss which will be reduced by the amount of the premium it
               received. Depending on the degree of correlation between the
               change in the value of its portfolio securities and changes in
               the value of the futures positions, the Fund's losses from
               existing options on futures may to some extent be reduced or
               increased by changes in the value of portfolio securities.

               The purchase of a put option on a futures contract is similar in
               some respects to the purchase of protective put options on
               portfolio securities. For example, the Fund may buy a put option
               on a futures contract to hedge its portfolio against the risk of
               falling prices or rising interest rates.

               The amount of risk the Fund assumes when it buys an option on a
               futures contract is the premium paid for the option plus related
               transaction costs. In addition to the correlation risks discussed
               above, the purchase of an option also entails the risk that
               changes

                                                                              25
<PAGE>

               in the value of the underlying futures contract will not be fully
               reflected in the value of the options bought.

               FORWARD CONTRACTS. A forward contract is an agreement between two
               parties in which one party is obligated to deliver a stated
               amount of a stated asset at a specified time in the future and
               the other party is obligated to pay a specified amount for the
               assets at the time of delivery. The Fund may enter into forward
               contracts to purchase and sell government securities, equity or
               income securities, foreign currencies or other financial
               instruments. Forward contracts generally are traded in an
               interbank market conducted directly between traders (usually
               large commercial banks) and their customers. Unlike futures
               contracts, which are standardized contracts, forward contracts
               can be specifically drawn to meet the needs of the parties that
               enter into them. The parties to a forward contract may agree to
               offset or terminate the contract before its maturity, or may hold
               the contract to maturity and complete the contemplated exchange.

               The following discussion summarizes the Fund's principal uses of
               forward foreign currency exchange contracts ("forward currency
               contracts"). The Fund may enter into forward currency contracts
               with stated contract values of up to the value of the Fund's
               assets. A forward currency contract is an obligation to buy or
               sell an amount of a specified currency for an agreed price (which
               may be in U.S. dollars or a foreign currency). The Fund will
               exchange foreign currencies for U.S. dollars and for other
               foreign currencies in the normal course of business and may buy
               and sell currencies through forward currency contracts in order
               to fix a price for securities it has agreed to buy or sell
               ("transaction hedge"). The Fund also may hedge some or all of its
               investments denominated in a foreign currency or exposed to
               foreign currency fluctuations against a decline in the value of
               that currency relative to the U.S. dollar by entering into
               forward currency contracts to sell an amount of that currency (or
               a proxy currency whose performance is expected to replicate or
               exceed the performance of that currency relative to the U.S.
               dollar) approximating the value of

 26
<PAGE>

               some or all of its portfolio securities denominated in that
               currency ("position hedge") or by participating in options or
               futures contracts with respect to the currency. The Fund also may
               enter into a forward currency contract with respect to a currency
               where the Fund is considering the purchase or sale of investments
               denominated in that currency but has not yet selected the
               specific investments ("anticipatory hedge"). In any of these
               circumstances the Fund may, alternatively, enter into a forward
               currency contract to purchase or sell one foreign currency for a
               second currency that is expected to perform more favorably
               relative to the U.S. dollar if the portfolio manager believes
               there is a reasonable degree of correlation between movements in
               the two currencies ("cross-hedge").

               These types of hedging minimize the effect of currency
               appreciation as well as depreciation, but do not eliminate
               fluctuations in the underlying U.S. dollar equivalent value of
               the proceeds of or rates of return on the Fund's foreign currency
               denominated portfolio securities. The matching of the increase in
               value of a forward contract and the decline in the U.S. dollar
               equivalent value of the foreign currency denominated asset that
               is the subject of the hedge generally will not be precise.
               Shifting the Fund's currency exposure from one foreign currency
               to another removes the Fund's opportunity to profit from
               increases in the value of the original currency and involves a
               risk of increased losses to the Fund if its portfolio manager's
               projection of future exchange rates is inaccurate. Proxy hedges
               and cross-hedges may result in losses if the currency used to
               hedge does not perform similarly to the currency in which hedged
               securities are denominated. Unforeseen changes in currency prices
               may result in poorer overall performance for the Fund than if it
               had not entered into such contracts.

               The Fund will cover outstanding forward currency contracts by
               maintaining liquid portfolio securities denominated in or whose
               value its tied to, the currency underlying the forward contract
               or the currency being hedged. To the extent that the Fund is not
               able to cover its forward currency positions with underlying

                                                                              27
<PAGE>

               portfolio securities, the Fund's custodian will segregate cash or
               other liquid assets having a value equal to the aggregate amount
               of the Fund's commitments under forward contracts entered into
               with respect to position hedges, cross-hedges and anticipatory
               hedges. If the value of the securities used to cover a position
               or the value of segregated assets declines, the Fund will find
               alternative cover or segregate additional cash or liquid assets
               on a daily basis so that the value of the covered and segregated
               assets will be equal to the amount of the Fund's commitments with
               respect to such contracts. As an alternative to segregating
               assets, the Fund may buy call options permitting the Fund to buy
               the amount of foreign currency being hedged by a forward sale
               contract or the Fund may buy put options permitting it to sell
               the amount of foreign currency subject to a forward buy contract.

               While forward contracts are not currently regulated by the CFTC,
               the CFTC may in the future assert authority to regulate forward
               contacts. In such event, the Fund's ability to utilize forward
               contracts may be restricted. In addition, the Fund may not always
               be able to enter into forward contracts at attractive prices and
               may be limited in its ability to use these contracts to hedge
               Fund assets.

               OPTIONS ON FOREIGN CURRENCIES. The Fund may buy and write options
               on foreign currencies in a manner similar to that in which
               futures or forward contracts on foreign currencies will be
               utilized. For example, a decline in the U.S. dollar value of a
               foreign currency in which portfolio securities are denominated
               will reduce the U.S. dollar value of such securities, even if
               their value in the foreign currency remains constant. In order to
               protect against such diminutions in the value of portfolio
               securities, the Fund may buy put options on the foreign currency.
               If the value of the currency declines, the Fund will have the
               right to sell such currency for a fixed amount in U.S. dollars,
               thereby offsetting, in whole or in part, the adverse effect on
               its portfolio.

               Conversely, when a rise in the U.S. dollar value of a currency in
               which securities to be acquired are denominated is projected,

 28
<PAGE>

               thereby increasing the cost of such securities, the Fund may buy
               call options on the foreign currency. The purchase of such
               options could offset, at least partially, the effects of the
               adverse movements in exchange rates. As in the case of other
               types of options, however, the benefit to the Fund from purchases
               of foreign currency options will be reduced by the amount of the
               premium and related transaction costs. In addition, if currency
               exchange rates do not move in the direction or to the extent
               projected, the Fund could sustain losses on transactions in
               foreign currency options that would require the Fund to forego a
               portion or all of the benefits of advantageous changes in those
               rates.

               The Fund may also write options on foreign currencies. For
               example, to hedge against a potential decline in the U.S. dollar
               value of foreign currency denominated securities due to adverse
               fluctuations in exchange rates, the Fund could, instead of
               purchasing a put option, write a call option on the relevant
               currency. If the expected decline occurs, the option will most
               likely not be exercised and the decline in value of portfolio
               securities will be offset by the amount of the premium received.

               Similarly, instead of purchasing a call option to hedge against a
               potential increase in the U.S. dollar cost of securities to be
               acquired, the Fund could write a put option on the relevant
               currency which, if rates move in the manner projected, should
               expire unexercised and allow the Fund to hedge the increased cost
               up to the amount of the premium. As in the case of other types of
               options, however, the writing of a foreign currency option will
               constitute only a partial hedge up to the amount of the premium.
               If exchange rates do not move in the expected direction, the
               option may be exercised and the Fund would be required to buy or
               sell the underlying currency at a loss which may not be offset by
               the amount of the premium. Through the writing of options on
               foreign currencies, the Fund also may lose all or a portion of
               the benefits which might otherwise have been obtained from
               favorable movements in exchange rates.

                                                                              29
<PAGE>

               The Fund may write covered call options on foreign currencies. A
               call option written on a foreign currency by the Fund is
               "covered" if the Fund owns the foreign currency underlying the
               call or has an absolute and immediate right to acquire that
               foreign currency without additional cash consideration (or for
               additional cash consideration held in a segregated account by its
               custodian) upon conversion or exchange of other foreign
               currencies held in its portfolio. A call option is also covered
               if the Fund has a call on the same foreign currency in the same
               principal amount as the call written if the exercise price of the
               call held (i) is equal to or less than the exercise price of the
               call written or (ii) is greater than the exercise price of the
               call written, if the difference is maintained by the Fund in cash
               or other liquid assets in a segregated account with the Fund's
               custodian.

               The Fund also may write call options on foreign currencies for
               cross-hedging purposes. A call option on a foreign currency is
               for cross-hedging purposes if it is designed to provide a hedge
               against a decline due to an adverse change in the exchange rate
               in the U.S. dollar value of a security which the Fund owns or has
               the right to acquire and which is denominated in the currency
               underlying the option. Call options on foreign currencies which
               are entered into for cross-hedging purposes are not covered.
               However, in such circumstances, the Fund will collateralize the
               option by segregating cash or other liquid assets in an amount
               not less than the value of the underlying foreign currency in
               U.S. dollars marked-to-market daily.

               OPTIONS ON SECURITIES. In an effort to increase current income
               and to reduce fluctuations in net asset value, the Fund may write
               covered put and call options and buy put and call options on
               securities that are traded on United States and foreign
               securities exchanges and over-the-counter. The Fund may write and
               buy options on the same types of securities that the Fund may
               purchase directly.

               A put option written by the Fund is "covered" if the Fund (i)
               segregates cash not available for investment or other liquid

 30
<PAGE>

               assets with a value equal to the exercise price of the put with
               the Fund's custodian or (ii) holds a put on the same security and
               in the same principal amount as the put written and the exercise
               price of the put held is equal to or greater than the exercise
               price of the put written. The premium paid by the buyer of an
               option will reflect, among other things, the relationship of the
               exercise price to the market price and the volatility of the
               underlying security, the remaining term of the option, supply and
               demand and interest rates.

               A call option written by the Fund is "covered" if the Fund owns
               the underlying security covered by the call or has an absolute
               and immediate right to acquire that security without additional
               cash consideration (or for additional cash consideration held in
               a segregated account by the Fund's custodian) upon conversion or
               exchange of other securities held in its portfolio. A call option
               is also deemed to be covered if the Fund holds a call on the same
               security and in the same principal amount as the call written and
               the exercise price of the call held (i) is equal to or less than
               the exercise price of the call written or (ii) is greater than
               the exercise price of the call written if the difference is
               maintained by the Fund in cash and other liquid assets in a
               segregated account with its custodian.

               The Fund also may write call options that are not covered for
               cross-hedging purposes. The Fund collateralizes its obligation
               under a written call option for cross-hedging purposes by
               segregating cash or other liquid assets in an amount not less
               than the market value of the underlying security,
               marked-to-market daily. The Fund would write a call option for
               cross-hedging purposes, instead of writing a covered call option,
               when the premium to be received from the cross-hedge transaction
               would exceed that which would be received from writing a covered
               call option and its portfolio manager believes that writing the
               option would achieve the desired hedge.

               The writer of an option may have no control over when the
               underlying securities must be sold, in the case of a call option,
               or

                                                                              31
<PAGE>

               bought, in the case of a put option, since with regard to certain
               options, the writer may be assigned an exercise notice at any
               time prior to the termination of the obligation. Whether or not
               an option expires unexercised, the writer retains the amount of
               the premium. This amount, of course, may, in the case of a
               covered call option, be offset by a decline in the market value
               of the underlying security during the option period. If a call
               option is exercised, the writer experiences a profit or loss from
               the sale of the underlying security. If a put option is
               exercised, the writer must fulfill the obligation to buy the
               underlying security at the exercise price, which will usually
               exceed the then market value of the underlying security.

               The writer of an option that wishes to terminate its obligation
               may effect a "closing purchase transaction." This is accomplished
               by buying an option of the same series as the option previously
               written. The effect of the purchase is that the writer's position
               will be canceled by the clearing corporation. However, a writer
               may not effect a closing purchase transaction after being
               notified of the exercise of an option. Likewise, an investor who
               is the holder of an option may liquidate its position by
               effecting a "closing sale transaction." This is accomplished by
               selling an option of the same series as the option previously
               bought. There is no guarantee that either a closing purchase or a
               closing sale transaction can be effected.

               In the case of a written call option, effecting a closing
               transaction will permit the Fund to write another call option on
               the underlying security with either a different exercise price or
               expiration date or both. In the case of a written put option,
               such transaction will permit the Fund to write another put option
               to the extent that the exercise price is secured by other liquid
               assets. Effecting a closing transaction also will permit the Fund
               to use the cash or proceeds from the concurrent sale of any
               securities subject to the option for other investments. If the
               Fund desires to sell a particular security from its portfolio on
               which it has written a call

 32
<PAGE>

               option, the Fund will effect a closing transaction prior to or
               concurrent with the sale of the security.

               The Fund will realize a profit from a closing transaction if the
               price of the purchase transaction is less than the premium
               received from writing the option or the price received from a
               sale transaction is more than the premium paid to buy the option.
               The Fund will realize a loss from a closing transaction if the
               price of the purchase transaction is more than the premium
               received from writing the option or the price received from a
               sale transaction is less than the premium paid to buy the option.
               Because increases in the market of a call option generally will
               reflect increases in the market price of the underlying security,
               any loss resulting from the repurchase of a call option is likely
               to be offset in whole or in part by appreciation of the
               underlying security owned by the Fund.

               An option position may be closed out only where a secondary
               market for an option of the same series exists. If a secondary
               market does not exist, the Fund may not be able to effect closing
               transactions in particular options and the Fund would have to
               exercise the options in order to realize any profit. If the Fund
               is unable to effect a closing purchase transaction in a secondary
               market, it will not be able to sell the underlying security until
               the option expires or it delivers the underlying security upon
               exercise. The absence of a liquid secondary market may be due to
               the following: (i) insufficient trading interest in certain
               options, (ii) restrictions imposed by a national securities
               exchange ("Exchange") on which the option is traded on opening or
               closing transactions or both, (iii) trading halts, suspensions or
               other restrictions imposed with respect to particular classes or
               series of options or underlying securities, (iv) unusual or
               unforeseen circumstances that interrupt normal operations on an
               Exchange, (v) the facilities of an Exchange or of the Options
               Clearing Corporation ("OCC") may not at all times be adequate to
               handle current trading volume, or (vi) one or more Exchanges
               could, for economic or other reasons, decide or be compelled at
               some future

                                                                              33
<PAGE>

               date to discontinue the trading of options (or a particular class
               or series of options), in which event the secondary market on
               that Exchange (or in that class or series of options) would cease
               to exist, although outstanding options on that Exchange that had
               been issued by the OCC as a result of trades on that Exchange
               would continue to be exercisable in accordance with their terms.

               The Fund may write options in connection with buy-and-write
               transactions. In other words, the Fund may buy a security and
               then write a call option against that security. The exercise
               price of such call will depend upon the expected price movement
               of the underlying security. The exercise price of a call option
               may be below ("in-the-money"), equal to ("at-the-money") or above
               ("out-of-the-money") the current value of the underlying security
               at the time the option is written. Buy-and-write transactions
               using in-the-money call options may be used when it is expected
               that the price of the underlying security will remain flat or
               decline moderately during the option period. Buy-and-write
               transactions using at-the-money call options may be used when it
               is expected that the price of the underlying security will remain
               fixed or advance moderately during the option period.
               Buy-and-write transactions using out-of-the-money call options
               may be used when it is expected that the premiums received from
               writing the call option plus the appreciation in the market price
               of the underlying security up to the exercise price will be
               greater than the appreciation in the price of the underlying
               security alone. If the call options are exercised in such
               transactions, the Fund's maximum gain will be the premium
               received by it for writing the option, adjusted upwards or
               downwards by the difference between the Fund's purchase price of
               the security and the exercise price. If the options are not
               exercised and the price of the underlying security declines, the
               amount of such decline will be offset by the amount of premium
               received.

               The writing of covered put options is similar in terms of risk
               and return characteristics to buy-and-write transactions. If the
               market price of the underlying security rises or otherwise is
               above the

 34
<PAGE>

               exercise price, the put option will expire worthless and the
               Fund's gain will be limited to the premium received. If the
               market price of the underlying security declines or otherwise is
               below the exercise price, the Fund may elect to close the
               position or take delivery of the security at the exercise price
               and the Fund's return will be the premium received from the put
               options minus the amount by which the market price of the
               security is below the exercise price.

               The Fund may buy put options to hedge against a decline in the
               value of its portfolio. By using put options in this way, the
               Fund will reduce any profit it might otherwise have realized in
               the underlying security by the amount of the premium paid for the
               put option and by transaction costs.

               The Fund may buy call options to hedge against an increase in the
               price of securities that it may buy in the future. The premium
               paid for the call option plus any transaction costs will reduce
               the benefit, if any, realized by the Fund upon exercise of the
               option, and, unless the price of the underlying security rises
               sufficiently, the option may expire worthless to the Fund.

               EURODOLLAR INSTRUMENTS. The Fund may make investments in
               Eurodollar instruments. Eurodollar instruments are U.S. dollar-
               denominated futures contracts or options thereon which are linked
               to the London Interbank Offered Rate ("LIBOR"), although foreign
               currency-denominated instruments are available from time to time.
               Eurodollar futures contracts enable purchasers to obtain a fixed
               rate for the lending of funds and sellers to obtain a fixed rate
               for borrowings. The Fund might use Eurodollar futures contracts
               and options thereon to hedge against changes in LIBOR, to which
               many interest rate swaps and fixed-income instruments are linked.

               SWAPS AND SWAP-RELATED PRODUCTS. The Fund may enter into interest
               rate swaps, caps and floors on either an asset-based or
               liability-based basis, depending upon whether it is hedging its
               assets or its liabilities, and will usually enter into interest
               rate swaps on a net basis (i.e., the two payment streams are
               netted

                                                                              35
<PAGE>

               out, with the Fund receiving or paying, as the case may be, only
               the net amount of the two payments). The net amount of the
               excess, if any, of the Fund's obligations over its entitlement
               with respect to each interest rate swap will be calculated on a
               daily basis and an amount of cash or other liquid assets having
               an aggregate net asset value at least equal to the accrued excess
               will be maintained in a segregated account by the Fund's
               custodian. If the Fund enters into an interest rate swap on other
               than a net basis, it would maintain a segregated account in the
               full amount accrued on a daily basis of its obligations with
               respect to the swap. The Fund will not enter into any interest
               rate swap, cap or floor transaction unless the unsecured senior
               debt or the claims-paying ability of the other party thereto is
               rated in one of the three highest rating categories of at least
               one NRSRO at the time of entering into such transaction. Janus
               Capital will monitor the creditworthiness of all counterparties
               on an ongoing basis. If there is a default by the other party to
               such a transaction, the Fund will have contractual remedies
               pursuant to the agreements related to the transaction.

               The swap market has grown substantially in recent years with a
               large number of banks and investment banking firms acting both as
               principals and as agents utilizing standardized swap
               documentation. Janus Capital has determined that, as a result,
               the swap market has become relatively liquid. Caps and floors are
               more recent innovations for which standardized documentation has
               not yet been developed and, accordingly, they are less liquid
               than swaps. To the extent the Fund sells (i.e., writes) caps and
               floors, it will segregate cash or other liquid assets having an
               aggregate net asset value at least equal to the full amount,
               accrued on a daily basis, of its obligations with respect to any
               caps or floors.

               There is no limit on the amount of interest rate swap
               transactions that may be entered into by the Fund. These
               transactions may in some instances involve the delivery of
               securities or other underlying assets by the Fund or its
               counterparty to collateralize obligations under the swap. Under
               the documentation currently

 36
<PAGE>

               used in those markets, the risk of loss with respect to interest
               rate swaps is limited to the net amount of the payments that the
               Fund is contractually obligated to make. If the other party to an
               interest rate swap that is not collateralized defaults, the Fund
               would risk the loss of the net amount of the payments that it
               contractually is entitled to receive. The Fund may buy and sell
               (i.e., write) caps and floors without limitation, subject to the
               segregation requirement described above.

               ADDITIONAL RISKS OF OPTIONS ON FOREIGN CURRENCIES, FORWARD
               CONTRACTS AND FOREIGN INSTRUMENTS. Unlike transactions entered
               into by the Fund in futures contracts, options on foreign
               currencies and forward contracts are not traded on contract
               markets regulated by the CFTC or (with the exception of certain
               foreign currency options) by the SEC. To the contrary, such
               instruments are traded through financial institutions acting as
               market-makers, although foreign currency options are also traded
               on certain Exchanges, such as the Philadelphia Stock Exchange and
               the Chicago Board Options Exchange, subject to SEC regulation.
               Similarly, options on currencies may be traded over the-counter.
               In an over-the-counter trading environment, many of the
               protections afforded to Exchange participants will not be
               available. For example, there are no daily price fluctuation
               limits, and adverse market movements could therefore continue to
               an unlimited extent over a period of time. Although the buyer of
               an option cannot lose more than the amount of the premium plus
               related transaction costs, this entire amount could be lost.
               Moreover, an option writer and a buyer or seller of futures or
               forward contracts could lose amounts substantially in excess of
               any premium received or initial margin or collateral posted due
               to the potential additional margin and collateral requirements
               associated with such positions.

               Options on foreign currencies traded on Exchanges are within the
               jurisdiction of the SEC, as are other securities traded on
               Exchanges. As a result, many of the protections provided to
               traders on organized Exchanges will be available with respect to

                                                                              37
<PAGE>

               such transactions. In particular, all foreign currency option
               positions entered into on an Exchange are cleared and guaranteed
               by the OCC, thereby reducing the risk of counterparty default.
               Further, a liquid secondary market in options traded on an
               Exchange may be more readily available than in the over-the-
               counter market, potentially permitting the Fund to liquidate open
               positions at a profit prior to exercise or expiration, or to
               limit losses in the event of adverse market movements.

               The purchase and sale of exchange-traded foreign currency
               options, however, is subject to the risks of the availability of
               a liquid secondary market described above, as well as the risks
               regarding adverse market movements, margining of options written,
               the nature of the foreign currency market, possible intervention
               by governmental authorities and the effects of other political
               and economic events. In addition, exchange-traded options on
               foreign currencies involve certain risks not presented by the
               over-the-counter market. For example, exercise and settlement of
               such options must be made exclusively through the OCC, which has
               established banking relationships in applicable foreign countries
               for this purpose. As a result, the OCC may, if it determines that
               foreign governmental restrictions or taxes would prevent the
               orderly settlement of foreign currency option exercises, or would
               result in undue burdens on the OCC or its clearing member, impose
               special procedures on exercise and settlement, such as technical
               changes in the mechanics of delivery of currency, the fixing of
               dollar settlement prices or prohibitions on exercise.

               In addition, options on U.S. government securities, futures
               contracts, options on futures contracts, forward contracts and
               options on foreign currencies may be traded on foreign exchanges
               and over-the-counter in foreign countries. Such transactions are
               subject to the risk of governmental actions affecting trading in
               or the prices of foreign currencies or securities. The value of
               such positions also could be adversely affected by (i) other
               complex foreign political and economic factors, (ii) lesser
               availability than

 38
<PAGE>

               in the United States of data on which to make trading decisions,
               (iii) delays in the Fund's ability to act upon economic events
               occurring in foreign markets during non-business hours in the
               United States, (iv) the imposition of different exercise and
               settlement terms and procedures and margin requirements than in
               the United States, and (v) low trading volume.

                                                                              39

INVESTMENT ADVISER
- --------------------------------------------------------------------------------

               As stated in the Prospectus, the Fund has an Investment Advisory
               Agreement with Janus Capital, 100 Fillmore Street, Denver,
               Colorado 80206-4928. The Advisory Agreement provides that Janus
               Capital will furnish continuous advice and recommendations
               concerning the Fund's investments, provide office space for the
               Fund, and pay the salaries, fees and expenses of all Fund
               officers and of those Trustees who are affiliated with Janus
               Capital. Janus Capital also may make payments to selected
               broker-dealer firms or institutions which perform recordkeeping
               or other services with respect to shareholder accounts. The
               minimum aggregate size required for eligibility for such
               payments, and the factors in selecting the broker-dealer firms
               and institutions to which they will be made, are determined from
               time to time by Janus Capital. Janus Capital is also authorized
               to perform the management and administrative services necessary
               for the operation of the Fund.

               The Fund pays custodian and transfer agent fees and expenses,
               brokerage commissions and dealer spreads and other expenses in
               connection with the execution of portfolio transactions, legal
               and accounting expenses, interest and taxes, registration fees,
               expenses of shareholders' meetings and reports to shareholders,
               fees and expenses of Trustees who are not affiliated with Janus
               Capital, costs of preparing, printing and mailing the Fund's
               Prospectus and SAI to current shareholders, and other costs of
               complying with applicable laws regulating the sale of Fund
               shares. Pursuant to the Advisory Agreement, Janus Capital
               furnishes certain other services, including net asset value
               determination and Fund accounting, recordkeeping, and blue sky
               registration and monitoring services, for which the Fund may
               reimburse Janus Capital for its costs.


               The Fund has agreed to compensate Janus Capital for its services
               by the monthly payment of a fee at the annual rate of 0.65% of
               the Fund's average daily net assets.



               The Advisory Agreement is dated April 3, 2000, and it will
               continue in effect until July 1, 2001, and thereafter from year
               to year so long as such continuance is approved annually by a
               majority of the Fund's Trustees who are not parties to the


 40
<PAGE>

               Advisory Agreement or interested persons of any such party, and
               by either a majority of the outstanding voting shares or the
               Trustees of the Fund. The Advisory Agreement i) may be terminated
               without the payment of any penalty by the Fund or Janus Capital
               on 60 days' 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 the Trustees who are not interested persons of
               the Fund or Janus Capital and, to the extent required by the 1940
               Act, the vote of a majority of the outstanding voting securities
               of the Fund.

               Janus Capital also acts as sub-adviser for a number of
               private-label mutual funds and provides separate account advisory
               services for institutional accounts. Investment decisions for
               each account managed by Janus Capital, including the Fund, are
               made independently from those for any other account that is or
               may in the future become managed by Janus Capital or its
               affiliates. If, however, a number of accounts managed by Janus
               Capital are contemporaneously engaged in the purchase or sale of
               the same security, the orders may be aggregated and/or the
               transactions may be averaged as to price and allocated equitably
               to each account. In some cases, this policy might adversely
               affect the price paid or received by an account or the size of
               the position obtained or liquidated for an account. Pursuant to
               an exemptive order granted by the SEC, the Fund and other funds
               advised by Janus Capital may also transfer daily uninvested cash
               balances into one or more joint trading accounts. Assets in the
               joint trading accounts are invested in money market instruments
               and the proceeds are allocated to the participating Funds on a
               pro rata basis.


               Kansas City Southern Industries, Inc. ("KCSI"), indirectly
               through its wholly-owned subsidiary, Stilwell Financial Inc. owns
               approximately 82% of the outstanding voting stock of Janus
               Capital. KCSI is a publicly traded holding company whose primary
               subsidiaries are engaged in transportation, information
               processing and financial services. Thomas H. Bailey, President
               and Chairman of the Board


                                                                              41
<PAGE>

               of Janus Capital, owns approximately 12% of its voting stock and,
               by agreement with KCSI, selects a majority of Janus Capital's
               Board.


               [TO BE UPDATED]



               KCSI has announced its intention to separate its transportation
               and financial services businesses. KCSI anticipates the
               separation to be completed in the first half of 2000.


               Each account managed by Janus Capital has its own investment
               objective and policies and is managed accordingly by a particular
               portfolio manager or team of portfolio managers. As a result,
               from time to time two or more different managed accounts may
               pursue divergent investment strategies with respect to
               investments or categories of investments.

               The Fund's portfolio manager is not permitted to purchase and
               sell securities for his own accounts except under the limited
               exceptions contained in the Fund's Code of Ethics ("Code"). The
               Fund's Code of Ethics is on file with and available from the SEC
               through the SEC Web site at www.sec.gov. The Code applies to
               Directors/Trustees of Janus Capital and the Fund, and employees
               of Janus Capital and the Trust and requires investment personnel
               and officers of Janus Capital, inside Directors/Trustees of Janus
               Capital and the Fund and certain other designated employees
               deemed to have access to current trading information to pre-clear
               all transactions in securities not otherwise exempt under the
               Code. Requests for trading authorization will be denied when,
               among other reasons, the proposed personal transaction would be
               contrary to the provisions of the Code or would be deemed to
               adversely affect any transaction known to be under consideration
               for or to have been effected on behalf of any client account,
               including the Fund.

               In addition to the pre-clearance requirement described above, the
               Code subjects such personnel to various trading restrictions and
               reporting obligations. All reportable transactions are required
               to be reviewed for compliance with the Code. Those persons also
               may

 42
<PAGE>

               be required under certain circumstances to forfeit their profits
               made from personal trading.

               The provisions of the Code are administered by and subject to
               exceptions authorized by Janus Capital.

                                                                              43

CUSTODIAN, TRANSFER AGENT AND
CERTAIN AFFILIATIONS
- --------------------------------------------------------------------------------

               State Street Bank and Trust Company, P.O. Box 0351, Boston,
               Massachusetts 02117-0351 is the custodian of the domestic
               securities and cash of the Fund. State Street and the foreign
               subcustodians selected by it and approved by the Trustees have
               custody of the assets of the Fund held outside the U.S. and cash
               incidental thereto. The custodian and subcustodians hold the
               Fund's assets in safekeeping and collect and remit the income
               thereon, subject to the instructions of the Fund.

               Janus Service Corporation, P.O. Box 173375, Denver, Colorado
               80217-3375, a wholly-owned subsidiary of Janus Capital, is the
               Fund's transfer agent. In addition, Janus Service provides
               certain other administrative, recordkeeping and shareholder
               relations services to the Fund. For transfer agency and other
               services, Janus Service receives a fee calculated at an annual
               rate of 0.16% of average net assets of the Fund and, in addition
               $4 per open shareholder account. In addition, the Fund pays DST
               Systems, Inc. ("DST"), a subsidiary of KCSI, license fees at the
               annual rate of $3.06 per shareholder account for the use of DST's
               shareholder accounting system. The Fund also pays DST $1.10 per
               closed shareholder account. The Fund pays DST for the use of its
               portfolio and fund accounting system a monthly base fee of $265
               to $1,323 based on the number of Janus funds using the system and
               an asset charge of $1 per million dollars of net assets (not to
               exceed $500 per month). In addition, the Fund pays DST postage
               and forms costs of a DST affiliate incurred in mailing Fund
               shareholder transaction confirmations.

               The Trustees have authorized the Fund to use another affiliate of
               DST as introducing broker for certain Fund portfolio transactions
               as a means to reduce Fund expenses through credits against the
               charges of DST and its affiliates with regard to commissions
               earned by such affiliate. See "Portfolio Transactions and
               Brokerage."

               Janus Distributors, Inc., 100 Fillmore Street, Denver, Colorado
               80206-4928, a wholly-owned subsidiary of Janus Capital, is a
               distributor of the Fund. Janus Distributors is registered as a

 44
<PAGE>

               broker-dealer under the Securities Exchange Act of 1934 and is a
               member of the National Association of Securities Dealers, Inc.
               Janus Distributors acts as the agent of the Fund in connection
               with the sale of its shares in all states in which the shares are
               registered and in which Janus Distributors is qualified as a
               broker-dealer. Under the Distribution Agreement, Janus
               Distributors continuously offers the Fund's shares and accepts
               orders at net asset value. No sales charges are paid by
               investors. Promotional expenses in connection with offers and
               sales of shares are paid by Janus Capital.

                                                                              45

PORTFOLIO TRANSACTIONS AND BROKERAGE
- --------------------------------------------------------------------------------

               Decisions as to the assignment of portfolio business for the Fund
               and negotiation of its commission rates are made by Janus
               Capital, whose policy is to obtain the "best execution" (prompt
               and reliable execution at the most favorable security price) of
               all portfolio transactions. The Fund may trade foreign securities
               in foreign countries because the best available market for these
               securities is often on foreign exchanges. In transactions on
               foreign stock exchanges, brokers' commissions are frequently
               fixed and are often higher than in the United States, where
               commissions are negotiated.

               In selecting brokers and dealers and in negotiating commissions,
               Janus Capital considers a number of factors, including but not
               limited to: Janus Capital's knowledge of currently available
               negotiated commission rates or prices of securities currently
               available and other current transaction costs; the nature of the
               security being traded; the size and type of the transaction; the
               nature and character of the markets for the security to be
               purchased or sold; the desired timing of the trade; the activity
               existing and expected in the market for the particular security;
               confidentiality; the quality of the execution, clearance and
               settlement services; financial stability of the broker or dealer;
               the existence of actual or apparent operational problems of any
               broker or dealer; rebates of commissions by a broker to the Fund
               or to a third party service provider to the Fund to pay Fund
               expenses; and research products or services provided. In
               recognition of the value of the foregoing factors, Janus Capital
               may place portfolio transactions with a broker or dealer with
               whom it has negotiated a commission that is in excess of the
               commission another broker or dealer would have charged for
               effecting that transaction if Janus Capital determines in good
               faith that such amount of commission was reasonable in relation
               to the value of the brokerage and research provided by such
               broker or dealer viewed in terms of either that particular
               transaction or of the overall responsibilities of Janus Capital.
               Research may include furnishing advice, either directly or
               through publications or writings, as to the value of

 46
<PAGE>


               securities, the advisability of purchasing or selling specific
               securities and the availability of securities or purchasers or
               sellers of securities; furnishing seminars, information, analyses
               and reports concerning issuers, industries, securities, trading
               markets and methods, legislative developments, changes in
               accounting practices, economic factors and trends and portfolio
               strategy; access to research analysts, corporate management
               personnel, industry experts, economists and government officials;
               comparative performance evaluation and technical measurement
               services and quotation services, and products and other services
               (such as third party publications, reports and analyses, and
               computer and electronic access, equipment, software, information
               and accessories that deliver, process or otherwise utilize
               information, including the research described above) that assist
               Janus Capital in carrying out its responsibilities. Most brokers
               and dealers used by Janus Capital provide research and other
               services described above.


               Janus Capital may use research products and services in servicing
               other accounts in addition to the Fund. If Janus Capital
               determines that any research product or service has a mixed use,
               such that it also serves functions that do not assist in the
               investment decision-making process, Janus Capital may allocate
               the costs of such service or product accordingly. Only that
               portion of the product or service that Janus Capital determines
               will assist it in the investment decision-making process may be
               paid for in brokerage commission dollars. Such allocation may
               create a conflict of interest for Janus Capital.

               Janus Capital does not enter into agreements with any brokers
               regarding the placement of securities transactions because of the
               research services they provide. It does, however, have an
               internal procedure for allocating transactions in a manner
               consistent with its execution policy to brokers that it has
               identified as providing superior execution and research,
               research-related products or services which benefit its advisory
               clients, including the Fund. Research products and services
               incidental to effecting securities transactions furnished by
               brokers or dealers may be used in

                                                                              47
<PAGE>

               servicing any or all of Janus Capital's clients and such research
               may not necessarily be used by Janus Capital in connection with
               the accounts which paid commissions to the broker-dealer
               providing such research products and services.

               Janus Capital may consider sales of Fund shares by a broker-
               dealer or the recommendation of a broker-dealer to its customers
               that they purchase Fund shares as a factor in the selection of
               broker-dealers to execute Fund portfolio transactions. Janus
               Capital may also consider payments made by brokers effecting
               transactions for the Fund i) to the Fund or ii) to other persons
               on behalf of the Fund for services provided to the Fund for which
               it would be obligated to pay. In placing portfolio business with
               such broker-dealers, Janus Capital will seek the best execution
               of each transaction.

               When the Fund purchases or sells a security in the over-the-
               counter market, the transaction takes place directly with a
               principal market-maker, without the use of a broker, except in
               those circumstances where in the opinion of Janus Capital better
               prices and executions will be achieved through the use of a
               broker.

               The Fund's Trustees have authorized Janus Capital to place
               transactions with DST Securities, Inc. ("DSTS"), a wholly-owned
               broker-dealer subsidiary of DST. Janus Capital may do so if it
               reasonably believes that the quality of the transaction and the
               associated commission are fair and reasonable and if, overall,
               the associated transaction costs, net of any credits described
               above under "Custodian, Transfer Agent and Certain Affiliations,"
               are lower than those that would otherwise be incurred.

PURCHASE OF SHARES
- --------------------------------------------------------------------------------


               Shares of the Fund are sold at the net asset value per share as
               determined at the close of the regular trading session of the New
               York Stock Exchange (the "NYSE") next occurring after a purchase
               order is received and accepted by the Fund. The Shareholder's
               Manual Section of the Prospectus contains detailed information
               about the purchase of shares.


NET ASSET VALUE DETERMINATION

               As stated in the Prospectus, the net asset value ("NAV") of Fund
               shares is determined once each day on which the New York Stock
               Exchange ("NYSE") is open, at the close of its regular trading
               session (normally 4:00 p.m., New York time, Monday through
               Friday). As stated in the Prospectus, the NAV of Fund shares is
               not determined on days the NYSE is closed (generally, New Year's
               Day, Presidents' Day, Martin Luther King Day, Good Friday,
               Memorial Day, Independence Day, Labor Day, Thanksgiving and
               Christmas). The per share NAV of the Fund is determined by
               dividing the total value of the Fund's securities and other
               assets, less liabilities, by the total number of shares
               outstanding. In determining NAV, securities listed on an
               Exchange, the NASDAQ National Market and foreign markets are
               valued at the closing prices on such markets, or if such price is
               lacking for the trading period immediately preceding the time of
               determination, such securities are valued at their current bid
               price. Municipal securities held by the Fund are traded primarily
               in the over-the-counter market. Valuations of such securities are
               furnished by one or more pricing services employed by the Fund
               and are based upon a computerized matrix system or appraisals
               obtained by a pricing service, in each case in reliance upon
               information concerning market transactions and quotations from
               recognized municipal securities dealers. Other securities that
               are traded on the over-the-counter market are valued at their
               closing bid prices. Foreign securities and currencies are
               converted to U.S. dollars using the exchange rate in effect at
               the close of the NYSE. The Fund will determine the market value
               of individual securities held by it, by using prices provided by
               one or more professional pricing services

                                                                              55

               which may provide market prices to other funds, or, as needed, by
               obtaining market quotations from independent broker-dealers.
               Short-term securities maturing within 60 days are valued on an
               amortized cost basis. Securities for which quotations are not
               readily available, and other assets, are valued at fair values
               determined in good faith under procedures established by and
               under the supervision of the Trustees.

               Trading in securities on European and Far Eastern securities
               exchanges and over-the-counter markets is normally completed well
               before the close of business on each business day in New York
               (i.e., a day on which the NYSE is open). In addition, European or
               Far Eastern securities trading generally or in a particular
               country or countries may not take place on all business days in
               New York. Furthermore, trading takes place in Japanese markets on
               certain Saturdays and in various foreign markets on days which
               are not business days in New York and on which the Fund's NAV is
               not calculated. The Fund calculates its NAV per share, and
               therefore effects sales, redemptions and repurchases of its
               shares, as of the close of the NYSE once on each day on which the
               NYSE is open. Such calculation may not take place
               contemporaneously with the determination of the prices of the
               foreign portfolio securities used in such calculation.

REINVESTMENT OF DIVIDENDS AND DISTRIBUTIONS

               If investors do not elect in writing or by phone to receive their
               dividends and distributions in cash, all income dividends and
               capital gains distributions, if any, on the Fund's shares are
               reinvested automatically in additional shares of the Fund at the
               NAV determined on the payment date. Checks for cash dividends and
               distributions and confirmations of reinvestments are usually
               mailed to shareholders within ten days after the record date. Any
               election of the manner in which a shareholder wishes to receive
               dividends and distributions (which may be made on the New Account
               Application form or by phone) will apply to dividends and
               distributions the record dates of which fall on or after the date
               that the Fund receives such notice. Changes to distribution

 56
<PAGE>

               options must be received at least three days prior to the record
               date to be effective for such date. Investors receiving cash
               distributions and dividends may elect in writing or by phone to
               change back to automatic reinvestment at any time.

                                                                              57

REDEMPTION OF SHARES
- --------------------------------------------------------------------------------

               Procedures for redemption of shares are set forth in the
               Shareholder's Manual section of the Prospectus. Shares normally
               will be redeemed for cash, although the Fund retains the right to
               redeem some or all of its shares in kind under unusual
               circumstances, in order to protect the interests of remaining
               shareholders, or to accommodate a request by a particular
               shareholder that does not adversely affect the interest of
               remaining shareholders, by delivery of securities selected from
               its assets at its discretion. However, the Fund is governed by
               Rule 18f-1 under the 1940 Act, which requires the Fund to redeem
               shares solely in cash up to the lesser of $250,000 or 1% of the
               NAV of the Fund during any 90-day period for any one shareholder.
               Should redemptions by any shareholder exceed such limitation, the
               Fund will have the option of redeeming the excess in cash or in
               kind. If shares are redeemed in kind, the redeeming shareholder
               might incur brokerage costs in converting the assets to cash. The
               method of valuing securities used to make redemptions in kind
               will be the same as the method of valuing portfolio securities
               described under "Purchase of Shares - Net Asset Value
               Determination" and such valuation will be made as of the same
               time the redemption price is determined.

               The right to require the Fund to redeem its shares may be
               suspended, or the date of payment may be postponed, whenever (1)
               trading on the NYSE is restricted, as determined by the SEC, or
               the NYSE is closed except for holidays and weekends, (2) the SEC
               permits such suspension and so orders, or (3) an emergency exists
               as determined by the SEC so that disposal of securities or
               determination of NAV is not reasonably practicable.

SHAREHOLDER ACCOUNTS
- --------------------------------------------------------------------------------


               Detailed information about the general procedures for shareholder
               accounts and specific types of accounts is set forth in the
               Prospectus and on our Web site. Applications for specific types
               of accounts may be obtained by calling the Fund at
               1-800-525-3713, writing to the Fund at P.O. Box 173375, Denver,
               Colorado 80217-3375 or by visiting our Web site at janus.com.


TELEPHONE AND WEB SITE TRANSACTIONS

               As stated in the Prospectus, shareholders may initiate a number
               of transactions by telephone and via our Web site. The Fund, its
               transfer agent and its distributor disclaim responsibility for
               the authenticity of instructions received by telephone and the
               Web site. Such entities will employ reasonable procedures to
               confirm that instructions communicated by telephone and the Web
               site are genuine. Such procedures may include, among others,
               requiring personal identification prior to acting upon telephone
               and Web site instructions, providing written confirmation of
               telephone and Web site transactions and tape recording telephone
               conversations.

SYSTEMATIC REDEMPTIONS

               As stated in the Shareholder's Manual section of the Prospectus,
               if you have a regular account or are eligible for distributions
               from a retirement plan, you may establish a systematic redemption
               option. The payments will be made from the proceeds of periodic
               redemptions of shares in the account at the NAV. Depending on the
               size or frequency of the disbursements requested, and the
               fluctuation in value of the Fund's portfolio, redemptions for the
               purpose of making such disbursements may reduce or even exhaust
               the shareholder's account. Either an investor or the Fund, by
               written notice to the other, may terminate the investor's
               systematic redemption option without penalty at any time.


               Information about requirements to establish a systematic
               redemption option may be obtained by writing or calling the Fund
               at the address or phone number shown above or by visiting our Web
               site at janus.com.


                                                                              59

TAX-DEFERRED ACCOUNTS
- --------------------------------------------------------------------------------

               The Fund offers several different types of tax-deferred accounts
               that an investor may establish to invest in Fund shares,
               depending on rules prescribed by the Code. Traditional and Roth
               Individual Retirement Accounts may be used by most individuals
               who have taxable compensation. Simplified Employee Pensions and
               Defined Contribution Plans (Profit Sharing or Money Purchase
               Pension Plans) may be used by most employers, including
               corporations, partnerships and sole proprietors, for the benefit
               of business owners and their employees. Education IRAs allow
               individuals, subject to certain income limitations, to contribute
               up to $500 annually on behalf of any child under the age of 18.
               In addition, the Fund offers a Section 403(b)(7) Plan for
               employees of educational organizations and other qualifying
               tax-exempt organizations. Investors should consult their tax
               adviser or legal counsel before selecting a tax-deferred account.

               Contributions under Traditional and Roth IRAs, Education IRAs,
               SEPs, Defined Contribution Plans and Section 403(b)(7) Plans are
               subject to specific contribution limitations. Generally, such
               contributions may be invested at the direction of the
               participant. The investment is then held by Investors Fiduciary
               Trust Company as custodian. Each participant's account is charged
               an annual fee of $12 per taxpayer identification number no matter
               how many tax-deferred accounts the participant has with Janus.
               The custodian reserves the right to change the amount of this fee
               or to waive it in whole or in part for certain types of accounts.

               Distributions from tax-deferred accounts may be subject to
               ordinary income tax and may be subject to an additional 10% tax
               if withdrawn prior to age 59 1/2 or used for a nonqualifying
               purpose. Additionally, shareholders generally must start
               withdrawing retirement plan assets no later than April 1 of the
               year after they reach age 70 1/2. Several exceptions to these
               general rules may apply and several methods exist to determine
               the amount and timing of the minimum annual distribution (if
               any). Shareholders should consult with their tax adviser or legal
               counsel prior to

 60
<PAGE>

               receiving any distribution from any tax-deferred account, in
               order to determine the income tax impact of any such
               distribution.


               To receive additional information about Traditional and Roth
               IRAs, SEPs, Defined Contribution Plans and Section 403(b)(7)
               Plans along with the necessary materials to establish an account,
               please call the Fund at 1-800-525-3713, write to the Fund at P.O.
               Box 173375, Denver, Colorado 80217-3375 or visit our Web site at
               janus.com. No contribution to a Traditional or Roth IRA, SEP,
               Defined Contribution Plan or Section 403(b)(7) Plan can be made
               until the appropriate forms to establish any such plan have been
               completed.


                                                                              61

INCOME DIVIDENDS, CAPITAL GAINS
DISTRIBUTIONS AND TAX STATUS
- --------------------------------------------------------------------------------

               It is a policy of the Fund to make distributions of substantially
               all of its investment income and any net realized capital gains.
               Any capital gains realized during each fiscal year of the Fund
               ended October 31, as defined by the Code, are normally declared
               and payable to shareholders in December. The Fund declares and
               makes annual distributions of income (if any). The Fund intends
               to qualify as a regulated investment company by satisfying
               certain requirements prescribed by Subchapter M of the Code.
               Accordingly, the Fund will invest no more than 25% of its total
               assets in a single issuer (other than U.S. government
               securities).

               The Fund may purchase securities of certain foreign corporations
               considered to be passive foreign investment companies by the IRS.
               In order to avoid taxes and interest that must be paid by the
               Fund, if these instruments are profitable, the Fund may make
               various elections permitted by the tax laws. However, these
               elections could require that the Fund recognize taxable income,
               which in turn must be distributed.

               Some foreign securities purchased by the Fund may be subject to
               foreign taxes which could reduce the yield on such securities.
               The amount of such foreign taxes is expected to be insignificant.
               The Fund may from year to year make the election permitted under
               Section 853 of the Code to pass through such taxes to
               shareholders, who will each decide whether to deduct such taxes
               or claim a foreign tax credit. If such election is not made,
               foreign taxes paid or accrued will represent an expense to the
               Fund which will reduce its investment company taxable income.

MISCELLANEOUS INFORMATION

- --------------------------------------------------------------------------------


               The Fund is a series of the Trust, a Massachusetts business trust
               that was created on February 11, 1986. The Trust is an open-end
               management investment company registered under the 1940 Act. As
               of the date of this SAI, the Trust offers 23 separate series,
               three of which currently offer three classes of shares.


               Janus Capital reserves the right to the name "Janus." In the
               event that Janus Capital does not continue to provide investment
               advice to the Fund, the Fund must cease to use the name "Janus"
               as soon as reasonably practicable.

               Under Massachusetts law, shareholders of the Fund could, under
               certain circumstances, be held liable for the obligations of the
               Fund. However, the Declaration of Trust disclaims shareholder
               liability for acts or obligations of the Fund and requires that
               notice of this disclaimer be given in each agreement, obligation
               or instrument entered into or executed by the Fund or the
               Trustees. The Declaration of Trust also provides for
               indemnification from the assets of the Fund for all losses and
               expenses of any Fund shareholder held liable for the obligations
               of the Fund. Thus, the risk of a shareholder incurring a
               financial loss on account of its liability as a shareholder of
               the Fund is limited to circumstances in which the Fund would be
               unable to meet its obligations. The possibility that these
               circumstances would occur is remote. The Trustees intend to
               conduct the operations of the Fund to avoid, to the extent
               possible, liability of shareholders for liabilities of the Fund.

SHARES OF THE TRUST

               The Trust is authorized to issue an unlimited number of shares of
               beneficial interest with a par value of one cent per share for
               each series of the Trust. Shares of the Fund are fully paid and
               nonassessable when issued. All shares of the Fund participate
               equally in dividends and other distributions by the Fund, and in
               residual assets of the Fund in the event of liquidation. Shares
               of the Fund have no preemptive, conversion or subscription
               rights. Shares of the Fund may be transferred by endorsement or
               stock

                                                                              63
<PAGE>

               power as is customary, but the Fund is not bound to recognize any
               transfer until it is recorded on its books.

SHAREHOLDER MEETINGS

               The Trust does not intend to hold annual shareholder meetings.
               However, special meetings may be called for a specific Fund or
               for the Trust as a whole for purposes such as electing or
               removing Trustees, terminating or reorganizing the Trust,
               changing fundamental policies, or for any other purpose requiring
               a shareholder vote under the 1940 Act. Separate votes are taken
               by the Fund only if a matter affects or requires the vote of only
               the Fund or the Fund's interest in the matter differs from the
               interest of other portfolios of the Trust. As a shareholder, you
               are entitled to one vote for each share that you own.

VOTING RIGHTS

               The present Trustees were elected at a meeting of shareholders
               held on July 10, 1992, with the exception of Mr. Craig and Mr.
               Rothe who were appointed by the Trustees as of June 30, 1995 and
               January 1, 1997, respectively. Under the Declaration of Trust,
               each Trustee will continue in office until the termination of the
               Trust or his earlier death, retirement, resignation, bankruptcy,
               incapacity or removal. Vacancies will be filled by a majority of
               the remaining Trustees, subject to the 1940 Act. Therefore, no
               annual or regular meetings of shareholders normally will be held,
               unless otherwise required by the Declaration of Trust or the 1940
               Act. Subject to the foregoing, shareholders have the power to
               vote to elect or remove Trustees, to terminate or reorganize the
               Fund, to amend the Declaration of Trust, to bring certain
               derivative actions and on any other matters on which a
               shareholder vote is required by the 1940 Act, the Declaration of
               Trust, the Trust's Bylaws or the Trustees.

               As mentioned above in "Shareholder Meetings," each share of the
               Fund and of each other series of the Trust has one vote (and
               fractional votes for fractional shares). Shares of all series of
               the Trust have noncumulative voting rights, which means that the

 64
<PAGE>

               holders of more than 50% of the shares of all series of the Trust
               voting for the election of Trustees can elect 100% of the
               Trustees if they choose to do so and, in such event, the holders
               of the remaining shares will not be able to elect any Trustees.

MASTER/FEEDER OPTION

               The Trust may in the future seek to achieve the Fund's objective
               by investing all of the Fund's assets in another investment
               company having the same investment objective and substantially
               the same investment policies and restrictions as those applicable
               to the Fund. Unless otherwise required by law, this policy may be
               implemented by the Trustees without shareholder approval.

INDEPENDENT ACCOUNTANTS

               PricewaterhouseCoopers LLP, 950 Seventeenth Street, Suite 2500,
               Denver, Colorado 80202, independent accountants for the Fund,
               audit the Fund's annual financial statements and prepare its tax
               returns.

REGISTRATION STATEMENT

               The Trust has filed with the SEC, Washington, D.C., a
               Registration Statement under the Securities Act of 1933, as
               amended, with respect to the securities to which this SAI

PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------

               Quotations of average annual total return for the Fund will be
               expressed in terms of the average annual compounded rate of
               return of a hypothetical investment in the Fund over periods of
               1, 5, and 10 years (up to the life of the Fund). These are the
               annual total rates of return that would equate the initial amount
               invested to the ending redeemable value. These rates of return
               are calculated pursuant to the following formula: P(1 + T)n = ERV
               (where P = a hypothetical initial payment of $1,000, T = the
               average annual total return, n = the number of years and
               ERV = the ending redeemable value of a hypothetical $1,000
               payment made at the beginning of the period). All total return
               figures reflect the deduction of a proportional share of Fund
               expenses on an annual basis, and assume that all dividends and
               distributions are reinvested when paid.


               From time to time in advertisements or sales material, the Fund
               may discuss its performance ratings or other information as
               published by recognized mutual fund statistical rating services,
               including, but not limited to, Lipper Analytical Services, Inc.,
               ("Lipper") Ibbotson Associates, Micropal or Morningstar, Inc.
               ("Morningstar") or by publications of general interest such as
               Forbes, Money, The Wall Street Journal, Mutual Funds Magazine,
               Kiplinger's or Smart Money. The Fund may also compare its
               performance to that of other selected mutual funds (for example,
               peer groups created by Lipper or Morningstar), mutual fund
               averages or recognized stock market indicators, including, but
               not limited to, the S&P 500 Index, the Dow Jones Industrial
               Average and the NASDAQ composite. In addition, the Fund may
               compare its total return to the yield on U.S. Treasury
               obligations and to the percentage change in the Consumer Price
               Index. Such performance ratings or comparisons may be made with
               funds that may have different investment restrictions,
               objectives, policies or techniques than the Fund and such other
               funds or market indicators may be comprised of securities that
               differ significantly from the Fund's investments.

EXPLANATION OF RATING CATEGORIES

               The following is a description of credit ratings issued by two of
               the major credit ratings agencies. Credit ratings evaluate only
               the safety of principal and interest payments, not the market
               value risk of lower quality securities. Credit rating agencies
               may fail to change credit ratings to reflect subsequent events on
               a timely basis. Although Janus Capital considers security ratings
               when making investment decisions, it also performs its own
               investment analysis and does not rely solely on the ratings
               assigned by credit agencies.

               Unrated securities will be treated as noninvestment grade
               securities unless the portfolio manager determines that such
               securities are the equivalent of investment grade securities.
               Securities that have received ratings from more than one agency
               are considered investment grade if at least one agency has rated
               the security investment grade.

ITEM 24. PERSONS CONTROLLED BY OR UNDER COMMON CONTROL WITH FUND

                  None

ITEM 25. INDEMNIFICATION

     Article VIII of Janus Investment Fund's Agreement and Declaration of
Trust provides for indemnification of certain persons acting on behalf of the
Funds. In general, Trustees and officers will be indemnified against liability
and against all expenses of litigation incurred by them in connection with any
claim, action, suit or proceeding (or settlement of the same) in which they
become involved by virtue of their Fund office, unless their conduct is
determined to constitute willful misfeasance, bad faith, gross negligence or
reckless disregard of their duties, or unless it has been determined that they
have not acted in good faith in the reasonable belief that their actions were in
or not opposed to the best interests of the Funds. A determination that a person
covered by the indemnification provisions is entitled to indemnification may be
made by the court or other body before which the proceeding is brought, or by
either a vote of a majority of a quorum of Trustees who are neither "interested
persons" of the Trust nor parties to the proceeding or by an independent legal
counsel in a written opinion. The Funds also may advance money for these
expenses, provided that the Trustee or officer undertakes to repay the Funds if
his conduct is later determined to preclude indemnification, and that either he
provide security for the undertaking, the Trust be insured against losses
resulting from lawful advances or a majority of a quorum of disinterested
Trustees, or independent counsel in a written opinion, determines that he
ultimately will be found to be entitled to indemnification. The Trust also
maintains a liability insurance policy covering its Trustees and officers.

     1. The beneficial interest in the Orion Fund shall be represented by a
separate series of shares of beneficial interest, par value one cent ($.01) per

which it relates and shall represent the beneficial interest only in such Orion
Fund. An unlimited number of Shares of such series may be issued.

     2. The Orion Fund shall be authorized to invest in cash, securities,
instruments and other property as from time to time described in the Trust's
then effective registration statement under the Securities Act of 1933 and the
Investment Company Act of 1940, as amended.

     3. The Shares of the Orion Fund shall have the additional relative
rights and preferences, shall be subject to the liabilities, shall have the

Without limitation of the foregoing sentence, each Share of such series shall be

Declaration and applicable law, this Certificate of Designation may be amended
by an instrument in writing signed by a Majority of the Trustees (OR BY AN

of the Orion Fund, such amendment may be adopted by an instrument in writing
signed by a Majority of the Trustees (or by an officer of the Trust pursuant to
the vote of a Majority of the Trustees) when authorized to do so by the vote in
accordance with Section 7.1 of the Declaration of the holders of a majority of
all the Shares of the Orion Fund outstanding and entitled to vote.

control over its own investment policies. However, the Trustees may delegate to
the appropriate officers of the Trust, or to a committee of the Trustees, the
power to authorize purchases, sales or other actions affecting the portfolio of
the Fund in the interim between meetings of the Trustees.

     8. TERMINATION. This Agreement may be terminated at any time, without

may be terminated by JCC at any time, without penalty, by giving sixty (60) days
advance written notice of termination to the Trust, addressed to its principal
place of business. The Trust agrees that, consistent with the terms of the Trust
Instrument, the Trust shall cease to use the name "Janus" in

connection with the Fund as soon as reasonably practicable following any
termination of this Agreement if JCC does not continue to provide investment
advice to the Fund after such termination.

specifically approved at least annually by the vote of a majority of the
Trustees of the Trust who are not parties hereto or interested persons of any
such party, cast in person at a meeting called for the purpose of voting on the
approval of the terms of such renewal, and by either the Trustees of the Trust
or the affirmative vote of a majority of the outstanding voting securities of
the Trust. The annual approvals provided for herein shall be effective to
continue this Agreement from year to year if given within a period beginning not
more than ninety (90) days prior to July 1 of each applicable year,
notwithstanding the fact that more than three hundred sixty-five (365) days may
have elapsed since the date on which such approval was last given.

     11. AMENDMENTS. This Agreement may be amended by the parties only if
such amendment is specifically approved (i) by a majority of the Trustees,
including a majority of the Trustees who are not interested persons (as that
phrase is defined in Section 2(a)(19) of the 1940 Act) of JCC and, if required
by applicable law, (ii) by the affirmative vote of a majority of the outstanding
voting securities of the Fund (as that phrase is defined in Section 2(a)(42) of
the 1940 Act).

appropriate allocation of the Trust's expenses (other than those directly
attributable to the Fund) between the Fund and the other series of the Trust.

     13. LIMITATION OF PERSONAL LIABILITY. All the parties hereto
acknowledge and agree that all liabilities of the Trust arising, directly or
indirectly, under this Agreement, of any and every nature whatsoever, shall be
satisfied solely out of the assets of the Fund and that no Trustee, officer or
holder of shares of beneficial interest of the Trust shall be personally liable
for any of the foregoing liabilities. The Trust Instrument describes in detail
the respective responsibilities and limitations on liability of the Trustees,
officers and holders of shares of beneficial interest of the Trust.

<PAGE>

     14. LIMITATION OF LIABILITY OF JCC. JCC shall not be liable for any
error of judgment or mistake of law or for any loss arising out of any
investment or for any act or omission taken with respect to the Trust, except
for willful misfeasance, bad faith or gross negligence in the performance of its
duties, or by reason of reckless disregard of its obligations and duties
hereunder and except to the extent otherwise provided by law. As used in this
Section 14, "JCC" shall include any affiliate of JCC performing services for the
Trust contemplated hereunder and directors, officers and employees of JCC and
such affiliates.

     15. ACTIVITIES OF JCC. The services of JCC to the Trust hereunder are
not to be deemed to be exclusive, and JCC and its affiliates are free to render
services to other parties. It is understood that trustees, officers and
shareholders of the Trust are or may become interested in JCC as directors,
officers and shareholders of JCC, that directors, officers, employees and
shareholders of JCC are or may become similarly interested in the Trust, and

effect or hereafter amended, and the rules and regulations thereunder, subject
to such orders, exemptions and interpretations as may be issued by the

officers to execute this Investment Advisory Agreement as of the date and year

Re:      Public Offering of Janus Orion Fund

Gentlemen:

I have acted as counsel for Janus Investment Fund, a Massachusetts business
trust (the "Trust"), in connection with the filing with the Securities and
Exchange Commission of a post-effective amendment to the Trust's registration
statement with respect to the proposed sale of shares of beneficial interest,
$0.01 par value, of Janus Orion Fund (the "Shares").

I have examined the Trust's Agreement and Declaration of Trust and Bylaws, as
amended, the proceedings of its trustees relating to the authorization, issuance
and proposed sale of the Shares, and such other records and documents as I have
deemed relevant. Based upon such examination, it is my opinion that upon the
issuance and sale of the Shares in the manner contemplated by the aforesaid
post-effective amendment to the Trust's registration statement, such Shares will
be legally issued, fully paid and nonassessable.

I hereby consent to the filing of this opinion as an exhibit to the
above-referenced registration statement. This opinion is for the exclusive use
of the Trust in connection with the filing of such post-effective amendment to
the Trust's registration statement with the Securities and Exchange Commission
(and certain state securities commissions) and is not to be used, circulated,
quoted, relied upon or otherwise referred to by any other person or for any
other purpose. This opinion is given as of the date hereof and I render no
opinion and disclaim any obligation to revise or supplement this opinion based
upon any change in applicable law or any factual matter that occurs or comes to
my attention after the date hereof.

Very truly yours,



Thomas A. Early
Vice President and General Counsel
