     PROSPECTUS HIGHLIGHTS

          The following summary is qualified in its entirety by the more
      detailed information appearing in the body of this Prospectus and in the
      Statement of Additional Information.
   
          The Legg Mason Income Trust, Inc. ("Corporation") is a diversified
      open-end management investment company which currently has four
      portfolios: the Legg Mason U.S. Government Intermediate-Term Portfolio
      ("Government Intermediate"), the Legg Mason Investment Grade Income
      Portfolio ("Investment Grade"), the Legg Mason High Yield Portfolio ("High
      Yield") and the Legg Mason U.S. Government Money Market Portfolio
      ("Government Money Market") (each a "Fund").
    

   
          GOVERNMENT INTERMEDIATE is a professionally managed portfolio seeking
      to provide investors with high current income consistent with prudent
      investment risk and liquidity needs. In seeking to achieve the Fund's
      objective, the Corporation's investment adviser, Western Asset Management
      Company ("Western Asset" or "Adviser"), under normal circumstances,
      invests at least 75% of the Fund's total assets in obligations issued or
      guaranteed by the U.S. Government, its agencies or instrumentalities, or
      instruments secured by such securities. The Fund expects to maintain an
      average dollar-weighted maturity of between three and ten years.
    
          The Adviser believes that shares of the Fund may be appropriate both
      for direct investment and for investment by Individual Retirement Accounts
      and other qualified retirement plans. The value of the debt instruments
      held by the Fund, and thus the net asset value of Fund shares, generally
      fluctuate inversely with movements in market interest rates. Certain
      investment grade debt securities in which the Fund invests may have
      speculative characteristics. The Fund's participation in hedging and
      option income strategies also involves certain investment risks and
      transaction costs.

          INVESTMENT GRADE is a professionally managed portfolio seeking to
      provide investors with a high level of current income through investment
      in a diversified portfolio of debt securities. In seeking to achieve the
      Fund's objective, the Adviser, under normal circumstances, invests
      primarily in fixed-income securities which the Adviser considers to be of
      investment grade, i.e., securities rated within the four highest grades by
      Moody's Investors Service, Inc. ("Moody's") or Standard & Poor's ("S&P"),
      securities comparably rated by another nationally recognized statistical
      rating organization ("NRSRO"), or unrated securities judged by the Adviser
      to be of comparable quality.
          The Adviser believes that shares of the Fund may be appropriate both
      for direct investment and for investment in Individual Retirement Accounts
      and other qualified retirement plans.
   
          The value of the debt instruments held by the Fund, and thus the net
      asset value of Fund shares, generally fluctuate inversely with movements
      in market interest rates. Certain investment grade debt securities in
      which the Fund invests may have speculative characteristics. The Fund may
      invest up to 25% of its total assets in debt securities rated below
      investment grade, commonly known as "junk bonds." Such securities are
      considered speculative and involve increased risk of exposure to adverse
      business and economic conditions. The Fund's participation in hedging and
      option income strategies also involves certain investment risks and
      transaction costs.
    

          HIGH YIELD is a professionally managed portfolio seeking to provide
      investors with a high level of current income. As a secondary objective,
      the Fund seeks capital appreciation. In seeking to achieve the Fund's
      objectives, the Adviser, under normal circumstances, invests at least 65%
      of the Fund's total assets in high yield, fixed-income securities
      (including those commonly known as "junk bonds"). Such securities are
      considered speculative and involve increased risk of exposure to adverse
      business and economic conditions. The value of debt instruments held by
      the Fund, and thus the net asset value of Fund shares, generally fluctuate
      inversely with movements in market interest rates.
          The Fund may invest up to 25% of its total assets in foreign
      securities. Investment in foreign securities entails certain additional
      risks, including risks arising from currency fluctuation, accounting
      systems and disclosure regulations that differ from those in the U.S., and
      political and economic changes in foreign countries. The Fund may have
      limited recourse against a foreign governmental

      issuer in the event of a default. The Fund's participation in hedging and
      option income strategies also involves certain risks. See page 18.
          The Fund may invest up to 25% of its total assets in securities
      restricted as to their disposition, which may include securities for which
      the Fund believes there is a liquid market. No more than 15% of the Fund's
      net assets will be invested in securities deemed by the Fund to be
      illiquid.
          An investment in the Fund does not constitute a complete investment
      program and is not appropriate for persons unwilling or unable to assume a
      high degree of risk.

          GOVERNMENT MONEY MARKET is a professionally managed portfolio seeking
      to obtain high current income consistent with liquidity and conservation
      of principal. In seeking to achieve the Fund's objective, the Adviser
      invests the Fund's assets in debt obligations issued or guaranteed by the
      U.S. Government, its agencies or instrumentalities, in repurchase
      agreements secured by such instruments, and in securities issued or
      guaranteed by multi-national development banks of which the U.S. is a
      member, such as the World Bank.
   
          The Adviser believes that shares of the Fund may be appropriate both
      for direct investment and for investment through Individual Retirement
      Accounts and other qualified retirement plans.
    

          Of course, there can be no assurance that any Fund will achieve its
      objective. See "Investment Objectives and Policies," page 8.

     EXPENSES

   
          The purpose of the following tables is to assist an investor in
      understanding the various costs and expenses that an investor in Primary
      Shares of a Fund will bear directly or indirectly. The expenses and fees
      set forth in the table are based on average net assets and annual Fund
      operating expenses related to Primary Shares for the year ended December
      31, 1997, adjusted for current expense and fee waiver levels.
    
   


      ANNUAL FUND OPERATING EXPENSES -- PRIMARY SHARES
      (AS A PERCENTAGE OF AVERAGE NET ASSETS)

                         GOVERNMENT    INVESTMENT   HIGH      MONEY
                        INTERMEDIATE     GRADE      YIELD     MARKET
                        ----------------------------------------------
      Management fees        0.34%(A)      0.21%(A)  0.65%      0.50%
      12b-1 fees             0.50%         0.50%     0.50%      0.10%(B)
      Other expenses         0.16%         0.29%     0.15%      0.15%

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

        expenses             1.00%(A)      1.00%(A)  1.30%      0.75%
                        ----------------------------------------------
    

      ---------------------
   
     (A) After fee waivers. LMFA has agreed to continue to waive fees to the
         extent the expenses attributable to Primary Shares (exclusive of taxes,
         interest, brokerage and extraordinary expenses) exceed during any month
         an annual rate of 1.00% of average daily net assets attributable to
         Primary Shares for such month, until the earlier of May 1, 1999, or,
         with respect to Government Intermediate, until its net assets reach
         $400 million, and with respect to Investment Grade, until its net
         assets reach $150 million, and unless extended will terminate on that
         date. In the absence of such waivers, the expected management fees,
         12b-1 fees, other expenses and total operating expenses would be as
         follows: for Government Intermediate: 0.55%, 0.50%, 0.16% and 1.21%,
         respectively; and for Investment Grade, 0.60%, 0.50%, 0.29% and 1.39%,
         respectively.
    
   
    (B) After fee waivers. Effective January 10, 1997, Government Money Market
        began compensating Legg Mason for distribution costs and services. The
        fee shown reflects determination by Legg Mason to request payment of,
        and determination by the Board to pay, less than the full amount of the
        authorized 12b-1 fee. If the full amount of the fee was paid, 12b-1 fees
        would be 0.20% and total operating expenses would be 0.85%.
    
          Because each Fund pays a 12b-1 fee with respect to Primary Shares,
      long-term shareholders in Primary Shares may pay more in distribution
      expenses than the economic equivalent of the maximum front-end sales
      charge permitted by the National Association of Securities Dealers, Inc.
      ("NASD"). For further information concerning the Funds' expenses, see "The
      Corporation's Board of Directors, Manager and Investment Adviser," page 27
      and "The Funds' Distributor," page 28.

      EXAMPLE
          The following example illustrates the expenses that you would pay on a
      $1,000 investment in Primary Shares over various time periods assuming (1)
      a 5% annual rate of return and (2) full redemption at the end of each time
      period. The Funds charge no redemption fees of any kind.

           GOVERNMENT      INVESTMENT     HIGH        MONEY
          INTERMEDIATE       GRADE        YIELD       MARKET

          ----------------------------------------------------
1 Year        $ 10            $ 10        $  13        $  8
3 Years       $ 32            $ 32        $  41        $ 24
5 Years       $ 55            $ 55        $  71        $ 42
10 Years      $122            $122        $ 157        $ 93

   
          This example assumes that all dividends and other distributions are
      reinvested and that the percentage amounts listed under "Annual Fund
      Operating Expenses" remain the same over the time periods shown. The above
      tables and the assumption in the example of a 5% annual return are
      required by regulations of the SEC applicable to all mutual funds. THE
      ASSUMED 5% ANNUAL RETURN IS NOT A PREDICTION OF, AND DOES NOT REPRESENT,
      THE PROJECTED OR ACTUAL PERFORMANCE OF PRIMARY SHARES OF THE FUNDS. THE
      ABOVE TABLES AND EXAMPLE SHOULD NOT BE CONSIDERED REPRESENTATIONS OF PAST
      OR FUTURE EXPENSES. ACTUAL EXPENSES MAY BE GREATER OR LESS THAN THOSE
      SHOWN. The actual expenses attributable to Primary Shares will depend
      upon, among other things, the level of average net assets, the levels of
      sales and redemptions of shares, the extent to which LMFA and/or Legg
      Mason waive their fees and the extent to which Primary Shares incur
      variable expenses, such as transfer agency costs.

          From time to time each bond fund may quote the TOTAL RETURN of each
      class of shares in advertisements or in reports or other communications to
      shareholders. A mutual fund's total return is a measurement of the overall
      change in value, including changes in share price and assuming
      reinvestment of dividends and capital gain distributions, of an investment
      in the fund. CUMULATIVE TOTAL RETURN shows the fund's performance over a
      specific period of time. AVERAGE ANNUAL TOTAL RETURN is the average annual
      compounded return that would have produced the same cumulative total
      return if the fund's performance had been constant over the entire period.
      Performance figures reflect past performance only and are not intended to
      indicate future performance. Average annual returns tend to smooth out
      variations in the fund's return, so they differ from actual year-by-year
      results.
          Total returns as of December 31, 1997 were as follows:

      (A) Inception of Government Intermediate and Investment Grade -- August 7,
          1987.

      (B) Inception of High Yield -- February 1, 1994.

          No adjustment has been made for any income taxes payable by
      shareholders. The investment return of each Fund will fluctuate. The
      principal value of an investment in each Fund (except Government Money
      Market) will fluctuate so that an investor's shares, when redeemed, may be
      worth more or less than their original cost. Returns of Government
      Intermediate and Investment Grade would have been lower if the Manager had
      not waived certain fees and expenses during the fiscal years 1987 through
      1997.
          Further information about each Fund's performance is contained in the
      Annual Report to Shareholders, which may be obtained without charge by
      calling your Legg Mason or affiliated financial advisor or Legg Mason's
      Funds Marketing Department at 800-822-5544.

GOVERNMENT INTERMEDIATE, INVESTMENT GRADE AND HIGH YIELD:
          Each Fund also may advertise its yield or effective yield. Yield
      reflects net investment income per share (as defined by applicable SEC
      regulations) over a 30-day (or one-month) period, expressed as an
      annualized percentage of net asset value at the end of the period. The
      effective yield, although calculated similarly, will be slightly higher
      than the yield because it assumes that income earned from the investment
      is reinvested (i.e., the compounding effect of reinvestment). Yield
      computations differ from other accounting methods and therefore may differ
      from dividends actually paid or reported net income.

GOVERNMENT MONEY MARKET:
          From time to time, the Fund may quote its yield, including a compound
      effective yield, in advertisements or in reports or other communications
      to shareholders. The Fund's "yield" refers to the income generated by an
      investment in the Fund over a stated seven-day period. This income is then
      "annualized." That is, the average daily net income generated by the
      investment during that week is assumed to be generated each day over a
      365-day period and is shown as a percentage of the investment. The
      "effective yield" is calculated similarly but assumes that the income
      earned by an investment is reinvested. The Fund's effective yield will be
      slightly higher than the Fund's yield because of the compounding effect of
      this assumed reinvestment.
          Yield information may be useful in reviewing the Fund's performance
      and providing a basis for comparison with other investment alternatives.
      However, the Fund's yield may change in response to fluctuations in
      interest rates and Fund expenses. Past performance is not a guarantee of
      future performance.
   
          The Fund's yield for the seven-day period ended December 31, 1997 was
      4.88%. The effective yield for the same period was 5.00%.

     INVESTMENT OBJECTIVES AND POLICIES

          Each Fund's investment objective may not be changed without
      shareholder approval; however, except as otherwise noted, the investment
      policies of each Fund described below may be changed by the Corporation's
      Board of Directors without a shareholder vote. There can be no assurance
      that any Fund will achieve its investment objective.

          GOVERNMENT INTERMEDIATE'S investment objective is to provide investors
      with high current income consistent with prudent investment risk and
      liquidity needs. At least 75% of the Fund's total assets are, under normal
      circumstances, invested in U.S. government securities or instruments
      secured by such securities, including repurchase agreements. The Fund
      expects to maintain an average dollar-weighted maturity of between three
      and ten years. In the case of obligations not backed by the full faith and
      credit of the United States, the Fund must look principally to the agency
      or instrumentality issuing or guaranteeing the obligation for ultimate
      repayment and may not be able to assert a claim against the United States
      itself in the event the agency or instrumentality does not meet its
      commitments. The U.S. Government does not guarantee the market value of
      the Fund's investments or the market value or yield of the Fund's shares,
      all of which will fluctuate as market interest rates change. Investments
      in mortgage-related securities issued by governmental or
      government-related entities, as described on page 13, will be included in
      the 75% limitation.
          The balance of the Fund, up to 25% of its total assets, normally is
      invested in cash, commercial paper and investment grade debt securities
      rated within one of the four highest grades assigned by S&P (AAA, AA, A or
      BBB) or Moody's (Aaa, Aa, A or Baa), securities comparably rated by
      another NRSRO, or unrated securities judged by the Adviser to be of
      comparable quality. Debt securities rated Baa are deemed by Moody's to
      have speculative characteristics; changes in economic conditions or other
      circumstances are more likely to lead to a weakened capacity for the
      issuers of such securities to make principal and interest payments than is
      the case for high-grade debt securities. A further description of Moody's
      and S&P's ratings is included in the Appendix to this Prospectus.

          INVESTMENT GRADE'S investment objective is to provide investors with a
      high level of current income through investment in a diversified portfolio
      of debt securities. In seeking to achieve its objective, the Fund invests
      primarily in fixed-income securities which the Adviser considers to be of
      investment grade, of which some may be privately placed and some may have
      equity features.
          In pursuing its objective, under normal circumstances, the Fund
      invests at least 75% of its total assets in the following types of
      investment grade fixed-income securities:
          (1) debt securities which are rated at the time of purchase within the
      four highest grades assigned by Moody's or S&P, or, if unrated by Moody's
      or S&P, judged by the Adviser to be of comparable quality.
          (2) securities of, or guaranteed by, the U.S. government, its agencies
      or instrumentalities.
          (3) commercial paper and other money market instruments which are
      rated A-1 or A-2 by S&P or Prime-1 or Prime-2 by Moody's at the date of
      investment, or if unrated by Moody's or S&P, judged by the Adviser to have
      investment quality comparable to securities which may be purchased under
      item (1); bank certificates of deposit; and bankers' acceptances.
          (4) preferred stocks (including step down preferred securities), rated
      no lower than Baa by Moody's or, if unrated by Moody's, judged by the
      Adviser to be of comparable quality.
          The remainder of the Fund's assets, not in excess of 25% of its total
      assets, may be invested in: (1) debt securities of issuers which are rated
      at the time of purchase below Moody's and S&P's four highest grades, but
      rated B or better by Moody's or S&P, or if unrated by Moody's or S&P,
      judged by the Adviser to be of comparable quality; and (2) securities
      which may be convertible into or exchangeable for, or carry warrants to
      purchase, common stock or other equity interests (such securities may
      offer attractive income opportunities, and the debt securities of certain
      issuers may not be available without such features).
          The Fund currently invests in debt securities with maturities ranging
      from short-term (including overnight) up to forty years and anticipates
      that it will continue to do so. The Fund expects to maintain its portfolio
      of securities so as to have an

8

<PAGE>
      average dollar-weighted maturity of between five and twenty years.

          HIGH YIELD'S investment objective is to provide investors with a high
      level of current income. As a secondary objective, the Fund seeks capital
      appreciation. In seeking to achieve the Fund's objectives, the Adviser,
      under normal circumstances, invests at least 65% of the Fund's total
      assets in high yield, fixed-income securities, that is, income producing
      debt securities and preferred stocks of all types, including corporate
      debt securities and preferred stock, convertible securities, zero coupon
      securities, deferred interest securities, mortgage-backed securities and
      asset-backed securities. The Fund's remaining assets may be held in cash
      or money market instruments, or invested in common stocks and other equity
      securities when these types of investments are consistent with the
      objectives of the Fund or are acquired as part of a unit consisting of a
      combination of fixed-income securities and equity investments. Such
      remaining assets may also be invested in fixed-income securities rated
      above BBB by S&P or Baa by Moody's, securities comparably rated by another
      NRSRO, or unrated securities deemed by the Adviser to be of equivalent
      quality. Moreover, the Fund may hold cash or money market instruments
      without limit for temporary defensive purposes or pending investment.
      Current yield is the primary consideration used by the Adviser in the
      selection of portfolio securities, although consideration may also be
      given to the potential for capital appreciation.
          Higher yields are generally available from securities rated BBB or
      lower by S&P, Baa or lower by Moody's, securities comparably rated by
      another NRSRO, or unrated securities of equivalent quality, and the Fund
      may invest all or a substantial portion of its assets in such securities.
      Debt securities rated below investment grade (i.e., below BBB/Baa) are
      deemed by these agencies to be predominantly speculative with respect to
      the issuer's capacity to pay interest and repay principal and may involve
      major risk or exposure to adverse conditions. The Fund may invest in
      securities rated as low as "C" by Moody's or "D" by S&P, which ratings
      indicate that the obligations are highly speculative and may be in default
      or in danger of default as to principal and interest. Ratings are only the
      opinions of the agencies issuing them and are not absolute guarantees as
      to quality. The Adviser does not rely solely on the ratings of rated
      securities in making investment decisions but also evaluates other
      economic and business factors affecting the issuer. The Appendix to this
      Prospectus describes Moody's and S&P's rating categories of securities in
      which the Fund may invest.
          Fixed-income securities in which the Fund may invest include preferred
      stocks and all types of debt obligations of both domestic and foreign
      issuers, commercial paper, and obligations issued or guaranteed by the
      U.S. Government, foreign governments or of any of their respective
      political subdivisions, agencies, or instrumentalities, including
      repurchase agreements secured by such instruments.
          The Fund may invest up to 25% of its total assets in private
      placements and securities which, though not registered at the time of
      their initial sale, are issued with registration rights. The Fund may also
      invest in securities traded pursuant to Rule 144A under the Securities Act
      of 1933. Rule 144A permits large institutions to trade certain securities
      even though they are not registered under that Act. Some of these
      securities may be deemed by the Adviser to be liquid. The Fund will not
      invest more than 5% of its total assets in any one issuer, except for
      issues of the U.S. Government, its agencies and instrumentalities or
      repurchase agreements collateralized by such securities; however, up to
      25% of the Fund's total assets may be invested in securities issued by
      Canadian provinces or by Crown Corporations whose obligations are
      guaranteed by either the Canadian federal government or a provincial
      government. No more than 25% of the Fund's total assets may be invested in
      issuers having their principal business activity in the same industry.

          GOVERNMENT MONEY MARKET'S investment objective is to obtain high
      current income consistent with liquidity and conservation of principal.
          The Fund invests only in U.S. government obligations, repurchase
      agreements secured by such instruments, and in securities issued or
      guaranteed by multi-national development banks of which the U.S. is a
      member, such as the World Bank. U.S. government obligations include (1)
      U.S. Treasury obligations, which differ only in their interest rates,
      maturities and times of issuance, and (2) obligations issued or guaranteed
      by U.S. government agencies and instrumentalities which are

                                                                               9

<PAGE>
   
      supported by any of the following: (a) the full faith and credit of the
      U.S. Government (such as certificates of the Government National Mortgage
      Association), (b) the right of the issuer to borrow an amount limited to a
      specific line of credit from the U.S. Government (such as obligations of
      the Federal Home Loan Bank), (c) the discretionary authority of the U.S.
      Treasury to lend to the issuer (such as Fannie Mae securities) or (d) only
      the credit of the instrumentality (such as Freddie Mac).
    
          In the case of obligations not backed by the full faith and credit of
      the United States, the Fund must look to the agency or instrumentality
      issuing or guaranteeing the obligation for ultimate repayment and may not
      be able to assert a claim against the United States itself in the event
      the agency or instrumentality does not meet its commitments.
          Multi-national development banks are not agencies or instrumentalities
      of the U.S. Government, and their securities are not guaranteed by any
      agency or instrumentality of the government. Banks of which the U.S. is a
      member may have a call on the U.S. Treasury for a specified amount of
      money which can be used only to support the banks' outstanding debt.
      However, the amount available from the Treasury for these purposes is only
      a portion of the amount of debt the banks typically have outstanding. The
      soundness of these banks may be affected by political and economic
      conditions in countries in which they carry on programs.
   
          The Fund will invest at least 65% of its total assets in securities
      issued or guaranteed by the U.S. Government, its agencies or
      instrumentalities and in repurchase agreements secured by such securities.
      The U.S. Government does not insure or guarantee the market value of the
      Fund's shares.
    
          The Fund attempts to stabilize the net asset value of a Fund share at
      $1.00. To maintain that net asset value, the Fund pursues several
      practices intended to minimize the effect of interest rate fluctuations.
      It invests in a portfolio of money market instruments with remaining
      maturities of 397 days or less; it maintains the dollar-weighted average
      maturity of the portfolio at 90 days or less; and it buys only high
      quality securities which the Adviser believes present minimal credit risk.
      The Fund, of course, cannot guarantee a net asset value of $1.00 per
      share. The Fund may invest in variable rate U.S. government obligations
      that have stated maturities in excess of 397 days if such obligations
      comply with conditions established by the SEC. Also, securities held by
      the Fund as collateral for repurchase agreements and other collateralized
      transactions may have remaining maturities in excess of 397 days.

GENERAL
          The market value of the interest-bearing debt securities held by a
      Fund, and therefore the net asset value of Fund shares, is affected by
      changes in market interest rates. There is normally an inverse
      relationship between the market value of securities sensitive to
      prevailing interest rates and actual changes in interest rates; i.e., a
      decline in interest rates produces an increase in market value, while an
      increase in rates produces a decrease in market value. Moreover, the
      longer the remaining maturity of a security, the greater is the effect of
      interest rate changes on the market value of such a security. In addition,
      changes in the ability of an issuer to make payments of interest and
      principal and in the market's perception of an issuer's creditworthiness
      also affect the market value of the debt securities of that issuer.
          Certain of the mortgage-backed and other securities in which a Fund
      can invest pay interest at variable or floating rates. Variable rate
      instruments reset at specified intervals, while floating rate instruments
      reset whenever there is a change in a specified index rate. The more
      closely these changes reflect current market rates, the more likely the
      instrument will trade at a price close to its par value. Some instruments
      do not directly track the underlying index, but reset based on formulas
      that can produce an effect similar to leverage; others may provide for
      interest payments that vary inversely with market rates. These instruments
      are regarded as "derivatives," and may vary significantly in market price
      when interest rates change.
          Each Fund has adopted certain fundamental investment limitations that,
      like its investment objective, may not be changed without the approval of
      its shareholders. A full description of these investment limitations is
      included in the Statement of Additional Information.

INVESTMENT TECHNIQUES AND RISKS
          The following investment techniques and risks apply to Government
      Intermediate, Investment Grade and High Yield unless otherwise stated.

10

<PAGE>
      CORPORATE DEBT SECURITIES
          Corporate debt securities may pay fixed or variable rates of interest,
      or interest at a rate contingent upon some other factor, such as the price
      of some commodity. These securities may be convertible into preferred or
      common equity, or may be bought as part of a unit containing common stock.
      In selecting corporate debt securities for a Fund, the Adviser reviews and
      monitors the creditworthiness of each issuer and issue. The Adviser also
      analyzes interest rate trends and specific developments which it believes
      may affect individual issuers.

      CALLABLE DEBT SECURITIES
          A debt security may be callable, i.e., subject to redemption at the
      option of the issuer at a price established in the security's governing
      instrument. If a debt security held by a Fund is called for redemption,
      that Fund will be required to permit the issuer to redeem the security or
      sell it to a third party. Either of these actions could have an adverse
      effect on a Fund's ability to achieve its investment objectives.

      RISKS OF LOWER-RATED DEBT SECURITIES
          Debt securities rated Baa and preferred stock rated Ba are deemed by
      Moody's to have speculative characteristics. Debt securities rated B by
      Moody's "generally lack characteristics of the desirable investment.
      Assurance of interest and principal payments or of maintenance of other
      terms of the contract over any long period of time may be small." S&P
      states that debt rated B "has a greater vulnerability to default but
      currently has the capacity to meet interest payments and principal
      repayments. Adverse business, financial or economic conditions will likely
      impair capacity or willingness to pay interest and repay principal."
          High yield bonds offer a higher yield to maturity than bonds with
      higher ratings, as compensation for holding an obligation that is subject
      to greater risk. The principal risks of high yield securities include: (i)
      limited liquidity and secondary market support, (ii) substantial market
      price volatility resulting from changes in prevailing interest rates,
      (iii) the fact that such obligations are often unsecured and are
      subordinated to the claims of banks and other senior lenders in bankruptcy
      proceedings, (iv) the operation of mandatory sinking fund or
      call/redemption provisions during periods of declining interest rates,
      whereby the holder might receive redemption proceeds at times when only
      lower-yielding securities are available for investment, (v) the
      possibility that earnings of the issuer may be insufficient to meet its
      debt service, (vi) the issuer's low creditworthiness and potential for
      insolvency during periods of rising interest rates and economic downturn,
      (vii) the fact that the issuers are often highly leveraged and may not
      have access to more traditional methods of financings and (viii) the
      possibility of adverse publicity and investor perceptions, whether or not
      due to fundamental analysis, which may result in widespread sales and
      declining market prices. If the Fund is required to seek recovery upon a
      default in the payment of principal or interest, it may incur additional
      expenses and may have limited legal recourse.
          As a result of the limited liquidity of high yield securities, their
      prices have at times experienced significant and rapid decline when a
      significant number of holders of high yield securities simultaneously
      decided to sell them. A decline is also likely in the high yield bond
      market during an economic downturn. An economic downturn or an increase in
      interest rates could severely disrupt the market for high yield securities
      and adversely affect the value of outstanding securities and the ability
      of the issuers to repay principal and interest. Yields on lower rated debt
      securities may rise dramatically in such periods, reflecting the risk that
      holders of such securities could lose a substantial portion of their value
      as a result of the issuers' financial restructuring or default. There can
      be no assurance that such declines will not recur. Because the market for
      high yield securities is less liquid, the valuation of these securities
      may require greater judgment than is necessary with respect to securities
      having more active markets.
          Although the prices of lower-rated bonds are generally less sensitive
      to interest rate changes than are higher-rated bonds, the prices of lower-
      rated bonds may be more sensitive to adverse economic changes and
      developments regarding the individual issuer. Although the market for
      lower-rated debt securities is not new, and the market has previously
      weathered economic downturns, there has been in recent years a substantial
      increase in the use of such securities to fund corporate acquisitions and
      restructurings. Accordingly, the past performance of the market for such
      securities may not be an accurate indication of its

                                                                              11

<PAGE>
      performance during future economic downturns or periods of rising interest
      rates.
          If an investment grade security purchased by Investment Grade is
      subsequently given a rating below investment grade, the Adviser will
      consider that fact in determining whether to retain that security in the
      Fund's portfolio.
          The table below provides a summary of ratings assigned to debt
      holdings in the portfolios of Investment Grade and High Yield. These
      figures are dollar-weighted averages of month-end portfolio holdings
      during the fiscal year ended December 31, 1997, presented as a percentage
      of total investments. These percentages are historical and are not
      necessarily indicative of the quality of current or future portfolio
      holdings, which may vary.

      The dollar-weighted average of debt securities not rated by either Moody's
      or S&P amounted to 6% for Investment Grade and 8% for High Yield. This may
      include securities rated by other NRSROs, as well as unrated securities.
      Unrated securities are not necessarily lower-quality securities, but may
      not be attractive to as many investors.
    
      U.S. GOVERNMENT SECURITIES (THE FOLLOWING ALSO APPLIES TO GOVERNMENT MONEY
      MARKET)
   
          U.S. government securities include direct obligations of the U.S.
      Treasury and obligations issued by U.S. government agencies and
      instrumentalities, including securities that are supported by: (1) the
      full faith and credit of the United States (e.g., certificates of the
      Government National Mortgage Association ("GNMA")); (2) the right of the
      issuer to borrow from the U.S. Treasury (e.g., Federal Home Loan Banks
      securities); (3) the discretionary authority of the U.S. Treasury to lend
      to the issuer (e.g., Fannie Mae securities); and (4) solely the
      creditworthiness of the issuer (e.g., Freddie Mac securities). Neither the
      U.S. Government nor any of its agencies or instrumentalities guarantees
      the market value of the securities they issue. Therefore, the market value
      of such securities can be expected to fluctuate in response to changes in
      interest rates.
    

      INFLATION-INDEXED SECURITIES
          The Funds may also invest in U.S. Treasury securities whose principal
      value is adjusted daily in accordance with changes to the Consumer Price
      Index (also known as "Treasury Inflation-Protection Securities"). Interest
      is calculated on the basis of the adjusted principal value on the payment
      date. The principal value of inflation-indexed securities declines in
      periods of deflation, but holders at maturity receive no less than par. If
      inflation is lower than expected during the period a Fund holds the
      security, the Fund may earn less on it than on a conventional bond. Any
      increase in principal value is taxable in the year the increase occurs,
      even though holders do not receive cash representing the increase at that
      time. Changes in market interest rates from causes other than inflation
      will likely affect the market prices of inflation-indexed securities in
      the same manner as conventional bonds.

      MORTGAGE-RELATED SECURITIES
          Mortgage-related securities represent interests in pools of mortgages.
      Mortgage-related securities may be issued by governmental or government-
      related entities or by non-governmental entities such as banks, savings
      and loan institutions, private mortgage insurance companies, mortgage
      bankers and other secondary market issuers.
          Mortgage-related securities differ from other forms of debt securities
      which normally provide for periodic payment of interest in fixed amounts
      with principal payments at maturity or specified call dates. In contrast,
      mortgage-related securities provide monthly payments which consist of
      interest and, in most cases, principal. In effect, these payments are a
      "pass-through" of the monthly payments made by the individual borrowers on
      their residential mortgage loans, net of any fees paid to the issuer or
      guarantor of such securities. Additional payments to holders of mortgage-
      related securities are caused by repayments resulting from the sale of the
      underlying residential property, refinancing or foreclosure. Some
      mortgage-related securities entitle the holders to receive all interest
      and principal payments owed on the

12

<PAGE>
      mortgages in the pool, net of certain fees, regardless of whether or not
      the mortgagors actually make the payments.
          As prepayment rates of individual pools of mortgage loans vary widely,
      it is not possible to predict accurately the average life of a particular
      mortgage-related security. Although mortgage-related securities are issued
      with stated maturities of up to forty years, unscheduled or early payments
      of principal and interest on the underlying mortgages may shorten
      considerably the securities' effective maturities. When interest rates are
      declining, such prepayments usually increase. On the other hand, a
      decrease in the rate of prepayments, resulting from an increase in market
      interest rates, among other causes, may extend the effective maturities of
      mortgage-related securities, increasing their sensitivity to changes in
      market interest rates. The volume of prepayments of principal on a pool of
      mortgages underlying a particular mortgage-related security will influence
      the yield of that security. Increased prepayment of principal may limit a
      Fund's ability to realize the appreciation in the value of such securities
      that would otherwise accompany declining interest rates. An increase in
      mortgage prepayments could cause a Fund to incur a loss on a
      mortgage-related security that was purchased at a premium. In determining
      a Fund's average maturity, the Adviser must apply certain assumptions and
      projections about the maturity and prepayment of mortgage-related
      securities; actual prepayment rates may differ.
          A Fund may enter into mortgage "dollar roll" transactions with
      selected banks and broker-dealers pursuant to which that Fund sells
      mortgage-backed securities for delivery in the future (generally within 30
      days) and simultaneously contracts to repurchase substantially similar
      securities on a specified future date.
          RESTRICTIONS: Government Intermediate and Investment Grade normally
      may invest up to 50% of their total assets in mortgage-related securities,
      including those issued by the governmental or government-related entities
      referred to above. No more than 25% of Government Intermediate's or
      Investment Grade's total assets normally are invested in mortgage-related
      securities issued by non-governmental entities. Mortgage dollar roll
      transactions may be considered borrowings and, if so, will be subject to
      each Fund's investment limitation that, except for temporary purposes, a
      Fund will not borrow money in excess of 5% of its total assets at the time
      of borrowing.

      GOVERNMENT MORTGAGE-RELATED SECURITIES
          GNMA pass-through securities are considered to have a very low risk of
      default in that (i) the underlying mortgage loan portfolio is comprised
      entirely of government-backed loans and (ii) the timely payment of both
      principal and interest on the securities is guaranteed by the full faith
      and credit of the U.S. Government. GNMA pass-through securities are,
      however, subject to the same market risk as comparable debt securities.
      Therefore, the effective maturity and market value of a Fund's GNMA
      securities can be expected to fluctuate in response to changes in interest
      rate levels.
   
          Freddie Mac, a corporate instrumentality of the U.S. Government,
      issues mortgage participation certificates ("PCs") which represent
      interests in mortgages from Freddie Mac's national portfolio. The mortgage
      loans in Freddie Mac's portfolio are not government backed; rather, the
      loans are either uninsured with loan-to-value ratios of 80% or less, or
      privately insured if the loan-to-value ratio exceeds 80%. Freddie Mac, not
      the U.S. Government, guarantees the timely payment of interest and
      ultimate collection of principal on Freddie Mac PCs.
    
   
          Fannie Mae is a government-sponsored corporation owned entirely by
      private stockholders that purchases residential mortgages from a list of
      approved seller/servicers, including savings and loan associations,
      savings banks, commercial banks, credit unions and mortgage bankers. Pass-
      through certificates issued by Fannie Mae ("Fannie Mae certificates") are
      guaranteed as to timely payment of principal and interest by Fannie Mae,
      not the U.S. Government.
    

      PRIVATELY ISSUED MORTGAGE-RELATED SECURITIES
   
          Mortgage-related securities offered by private issuers include
      pass-through securities comprised of pools of conventional residential
      mortgage loans; mortgage-backed bonds which are considered to be
      obligations of the institution issuing the bonds and are collateralized by
      mortgage loans; and bonds and collateralized mortgage obligations ("CMOs")
      which are collateralized by mortgage-related securities issued by Freddie
      Mac, Fannie Mae, or GNMA or by pools of conventional mortgages.
    

                                                                              13

<PAGE>
          CMOs are typically structured with two or more classes or series which
      have different maturities and are generally retired in sequence. Each
      class of obligations is scheduled to receive periodic interest payments
      according to the coupon rate on the obligations. However, all monthly
      principal payments and any prepayments from the collateral pool are paid
      first to the "Class 1" bondholders. The principal payments are such that
      the Class 1 obligations are scheduled to be completely repaid no later
      than, for example, five years after the offering date. Thereafter, all
      payments of principal are allocated to the next most senior class of bonds
      until that class of bonds has been fully repaid. Although full payoff of
      each class of bonds is contractually required by a certain date, any or
      all classes of obligations may be paid off sooner than expected because of
      an increase in the payoff speed of the pool.
          Mortgage-related securities created by non-governmental issuers
      generally offer a higher rate of interest than government and government-
      related securities because there are no direct or indirect government
      guarantees of payments in the former securities, resulting in higher
      risks.
          The market for conventional pools is smaller and less liquid than the
      market for the government and government-related mortgage pools.

      ASSET-BACKED SECURITIES
          Asset-backed securities are securities that represent direct or
      indirect participations in, or are secured by and payable from, assets
      such as motor vehicle installment sales contracts, installment loan
      contracts, leases of various types of real and personal property and
      receivables from revolving credit (credit card) agreements. Such assets
      are securitized through the use of trusts and special purpose
      corporations. The value of such securities partly depends on loan
      repayments by individuals, which may be adversely affected during general
      downturns in the economy. Payments or distributions of principal and
      interest on asset-backed securities may be supported by credit
      enhancements, such as various forms of cash collateral accounts or letters
      of credit. Like mortgage-related securities, asset-backed securities are
      subject to the risk of prepayment. The risk that recovery on repossessed
      collateral might be unavailable or inadequate to support payments on
      asset-backed securities, however, is greater than is the case for
      mortgage-backed securities.

      STRUCTURED SECURITIES (INVESTMENT GRADE AND HIGH YIELD ONLY)
          Investment Grade and High Yield may invest in structured securities.
      These securities pay interest and/or repay principal in amounts determined
      by the performance of one or more financial indices or securities.
      Structured securities may be more volatile than the underlying index or
      security. The issuer of these securities is typically a bank or securities
      dealer. The value of the security may be affected by the issuer's
      creditworthiness. Like other debt instruments, they are also affected by
      changes in market interest rates.

      CONVERTIBLE SECURITIES
          A convertible security is a bond, debenture, note, preferred stock or
      other security that may be converted into or exchanged for a prescribed
      amount of common stock of the same or a different issuer within a
      particular period of time at a specified price or formula. A convertible
      security entitles the holder to receive interest paid or accrued on debt
      or the dividend paid on preferred stock until the convertible security
      matures or is redeemed, converted or exchanged. Before conversion,
      convertible securities have characteristics similar to non-convertible
      debt securities in that they ordinarily provide a stable stream of income
      with generally higher yields than those of common stocks of the same or
      similar issuers, but lower than the yield on non-convertible debt.
      Convertible securities are usually subordinated to comparable-tier
      non-convertible securities but rank senior to common stock in a
      corporation's capital structure.
          The value of a convertible security is a function of (1) its yield in
      comparison with the yields of other securities of comparable maturity and
      quality that do not have a conversion privilege and (2) its worth, at
      market value, if converted into the underlying common stock. Convertible
      securities are typically issued by smaller capitalized companies, whose
      stock prices may be volatile. The price of a convertible security often
      reflects such variations in the price of the underlying common stock in a
      way that non-convertible debt does not. A convertible security may be
      subject to redemption at the option of the issuer at a price established
      in the convertible security's governing instrument, which could have an
      adverse

14

<PAGE>
      effect on a Fund's ability to achieve its investment objective.
          Government Intermediate and Investment Grade do not intend to exercise
      conversion rights for any convertible security they own and do not intend
      to hold any security which has been subject to conversion.

      ZERO COUPON BONDS
          Zero coupon bonds are debt obligations which make no fixed interest
      payments but instead are issued at a significant discount from face value.
      Like other debt securities, the market price can reflect a premium or
      discount, in addition to the original issue discount, reflecting the
      market's judgment as to the issuer's creditworthiness, the interest rate
      or other similar factors. The original issue discount approximates the
      total amount of interest the bonds will accrue and compound over the
      period until maturity or the first interest payment date at a rate of
      interest reflecting the market rate of the security at the time of
      issuance. Because zero coupon bonds do not make periodic interest
      payments, their prices can be very volatile when market interest rates
      change.
          The original issue discount on zero coupon bonds must be included in a
      Fund's income ratably as it accrues. Accordingly, to continue to qualify
      for tax treatment as a regulated investment company and to avoid a certain
      excise tax, a Fund may be required to distribute as a dividend an amount
      that is greater than the total amount of cash it actually receives. See
      "Additional Tax Information" in the Statement of Additional Information.
      These distributions must be made from a Fund's cash assets or, if
      necessary, from the proceeds of sales of portfolio securities. Such sales
      could occur at a time which would be disadvantageous to that Fund and when
      that Fund would not otherwise choose to dispose of the assets.

      STRIPPED MORTGAGE-BACKED SECURITIES
          The Funds may also invest in stripped mortgage-backed securities,
      which are derivative securities usually structured with two classes that
      receive different proportions of the interest and principal distributions
      from an underlying pool of mortgage assets. The Funds may purchase
      securities representing only the interest payment portion of the
      underlying mortgage pools (commonly referred to as "IOs") or only the
      principal portion of the underlying mortgage pools (commonly referred to
      as "POs"). Stripped mortgage-backed securities are more sensitive to
      changes in prepayment and interest rates and the market for such
      securities is less liquid than is the case for traditional debt securities
      and mortgage-backed securities. The yield on IOs is extremely sensitive to
      the rate of principal payments (including prepayments) on the underlying
      mortgage assets, and a rapid rate of repayment may have a material adverse
      effect on such securities' yield to maturity. If the underlying mortgage
      assets experience greater than anticipated prepayments of principal, a
      Fund will fail to recoup fully its initial investment in these securities,
      even if they are rated high quality. Most IOs and POs are regarded as
      illiquid and will be included in each Fund's limit on illiquid securities.
      U.S. government-issued IOs and POs backed by fixed-rate mortgages may be
      deemed liquid by the Adviser, following guidelines and standards
      established by the Corporation's Board of Directors.

      PAY-IN-KIND BONDS (HIGH YIELD ONLY)
          Pay-in-kind bonds pay "interest" through the issuance of additional
      bonds, thereby adding debt to the issuer's balance sheet. The market
      prices of these securities are likely to respond to changes in interest
      rates to a greater degree than the prices of securities paying interest
      currently. Pay-in-kind bonds carry additional risk in that, unlike bonds
      that pay interest throughout the period to maturity, the Fund will realize
      no cash until the cash payment date and the Fund may obtain no return at
      all on its investment if the issuer defaults.
   
          The holder of a pay-in-kind bond must accrue income with respect to
      the security prior to the receipt of cash payments thereon. To avoid
      liability for federal income and excise taxes, the Fund most likely will
      be required to distribute income accrued with respect to these securities,
      even though the Fund has not received that income in cash, and may be
      required to dispose of portfolio securities under disadvantageous
      circumstances in order to generate cash to satisfy these distribution
      requirements. See "Additional Tax Information" in the Statement of
      Additional Information.
    

      PREFERRED STOCK
          Preferred stock may be purchased as a substitute for debt securities
      of the same issuer when, in the opinion of the Adviser, the preferred
      stock is more attractively priced in light of the risks

                                                                              15

<PAGE>
      involved. Preferred stock pays dividends at a specified rate and generally
      has preference over common stock in the payment of dividends and the
      liquidation of the issuer's assets but is junior to the debt securities of
      the issuer in those same respects. Unlike interest payments on debt
      securities, dividends on preferred stock are generally payable at the
      discretion of the issuer's board of directors, and shareholders may suffer
      a loss of value if dividends are not paid. Preferred shareholders
      generally have no legal recourse against the issuer if dividends are not
      paid. The market prices of preferred stocks are subject to changes in
      interest rates and are more sensitive to changes in the issuer's
      creditworthiness than are the prices of debt securities. Under ordinary
      circumstances, preferred stock does not carry voting rights.

      TRUST ORIGINATED PREFERRED SECURITIES
   
          The Funds may also invest in trust originated preferred securities, a
      type of security issued by financial institutions such as banks and
      insurance companies. Trust originated preferred securities represent
      interests in a trust formed by a financial institution. The trust sells
      preferred shares and invests the proceeds in notes issued by the financial
      institution. These notes may be subordinated and unsecured. Distributions
      on the trust originated preferred securities match the interest payments
      on the notes; if no interest is paid on the notes, the trust will not make
      current payments on its preferred securities. Trust originated preferred
      securities currently enjoy favorable tax treatment. If the tax
      characterization of these securities were to change adversely, they could
      be redeemed by the issuers, which could result in a loss to a Fund. In
      addition, some trust originated preferred securities are restricted
      securities available only to qualified institutional buyers under Rule
      144A.
    

   
      MUNICIPAL OBLIGATIONS
    
   
          The Funds may invest up to 5% of their respective net assets in
      municipal obligations. Municipal obligations include obligations issued to
      obtain funds for various public purposes, including constructing a wide
      range of public facilities, such as bridges, highways, housing, hospitals,
      mass transportation, schools and streets.
    

      FOREIGN SECURITIES

GOVERNMENT INTERMEDIATE AND INVESTMENT GRADE:
          The Funds may invest in U.S. dollar-denominated debt securities issued
      by foreign companies and governments. The foreign government securities in
      which a Fund invests generally consist of obligations supported by
      national, state or provincial governments or similar political
      subdivisions. The Funds also may invest in debt securities of foreign
      "quasi-governmental agencies," which are issued by entities owned by a
      national, state or equivalent government or are obligations of a political
      unit that is not backed by the national government's full faith and credit
      and general taxing powers. Because the foreign securities in which the
      Funds invest are U.S. dollar-denominated, there is no risk of currency
      fluctuation, although there are other risks as set forth below.

HIGH YIELD:
          High Yield may invest up to 25% of its total assets in securities of
      domestic and foreign issuers that are denominated in currencies other than
      the U.S. dollar. To facilitate investment in foreign securities, the Fund
      may hold positions in foreign currencies. In addition, for hedging
      purposes, the Fund may purchase and write either listed or
      over-the-counter put and call options on foreign currencies or may enter
      into forward foreign currency contracts ("forward currency contracts").
          Forward currency contracts involve obligations to purchase or sell a
      specific amount of a specific currency at a future date, which may be any
      fixed number of days from the date of the contract agreed upon by the
      parties, at a price set at the time of the contract. By entering into a
      forward currency contract, the Fund "locks in" the exchange rate between
      the currency it will deliver and the currency it will receive for the
      duration of the contract. The Fund may enter into these contracts for the
      purpose of hedging against risk arising from its investment or anticipated
      investment in securities denominated in foreign currencies. Forward
      currency contracts involve certain risks, including the risk that currency
      movements will not be accurately predicted causing the Fund to sustain
      losses on these contracts.
          The Fund may invest in fixed-income and other debt securities of
      issuers based in emerging

16

<PAGE>
      markets (including countries in Latin America, Eastern Europe, Asia and
      Africa).

      RISKS OF FOREIGN SECURITIES
          Investment in foreign securities (including those denominated in U.S.
      dollars) presents certain risks, including those resulting from adverse
      political and economic developments, reduced availability of public
      information concerning issuers and the fact that foreign issuers generally
      are not subject to uniform accounting, auditing and financial reporting
      standards or to other regulatory practices and requirements comparable to
      those applicable to domestic issuers. Moreover, securities of many foreign
      issuers may be less liquid and their prices more volatile than those of
      comparable domestic issuers. Some foreign securities are subject to
      foreign income and withholding taxes. Additional risks associated with
      investing in foreign securities include the possibility of
      nationalization, expropriation or confiscatory taxation; adverse changes
      in investment or exchange control regulations (which may include
      suspension of the ability to transfer currency out of a country); and
      political instability. Changes in foreign exchange rates will affect the
      value of securities denominated or quoted in currencies other than the
      U.S. dollar irrespective of the performance of the underlying instrument.
      Some foreign governments have defaulted on principal and/or interest
      payments; in such cases, a Fund would have limited recourse to enforce its
      rights under the instruments it holds. The risks of foreign investment,
      described above, are greater for investments in emerging markets. Debt
      securities of issuers in such countries will typically be rated below
      investment grade or be of comparable quality.

      REPURCHASE AGREEMENTS (THE FOLLOWING ALSO APPLIES TO GOVERNMENT MONEY
      MARKET)
   
          Repurchase agreements are agreements under which U.S. government
      obligations or other high-quality, liquid debt securities are acquired
      from a securities dealer or bank subject to resale at an agreed-upon price
      and date. The securities are held for the Funds by a custodian bank as
      collateral until resold and will be supplemented by additional collateral
      if necessary to maintain a total value equal to or in excess of the value
      of the repurchase agreement. A Fund bears a risk of loss in the event that
      the other party to a repurchase agreement defaults on its obligations and
      that Fund is delayed or prevented from exercising its right to dispose of
      the collateral securities, which may decline in value in the interim. A
      Fund will enter into repurchase agreements only with financial
      institutions which the Adviser believes present minimal risk of default
      during the term of the agreement based on guidelines established by the
      Corporation's Board of Directors.
    
          RESTRICTIONS: A Fund will not enter into repurchase agreements of more
      than seven days' duration if more than 10% (15% in the case of High Yield)
      of its net assets would be invested in such agreements and other illiquid
      investments.

      FORWARD COMMITMENTS (THE FOLLOWING ALSO APPLIES TO GOVERNMENT MONEY
      MARKET)
          Each Fund may enter into commitments to purchase U.S. government
      securities or other securities on a "forward commitment" basis, including
      purchases on a "when-issued" basis or a "to be announced" basis. When such
      transactions are negotiated, the price is fixed at the time the commitment
      is made, but delivery and payment for the securities takes place at a
      later date. Such securities are often the most efficiently priced and have
      the best liquidity in the bond market. During the period between a
      commitment and settlement, no payment is made by the purchaser for the
      securities purchased and, thus, no interest accrues to the purchaser from
      the transaction. In a to be announced transaction, a Fund has committed to
      purchase securities for which all specific information is not yet known at
      the time of the trade, particularly the exact face amount in forward
      commitment mortgage-backed securities transactions.
          A Fund may sell the securities subject to a forward commitment
      purchase, which may result in a gain or loss. When a Fund purchases
      securities on a forward commitment basis, it assumes the risks of
      ownership, including the risk of price fluctuation, at the time of
      purchase, not at the time of receipt. Purchases of forward commitment
      securities also involve a risk of loss if the seller fails to deliver
      after the value of the securities has risen. Depending on market
      conditions, a Fund's forward commitment purchases could cause its net
      asset value to be more volatile. A Fund will direct State Street to place
      cash or U.S. government obligations in a separate account equal to the
      commitments of the Fund to purchase securities as a result of its forward
      commitment obligation.

                                                                              17

<PAGE>
          Each Fund (other than Government Money Market) may also enter into a
      forward commitment to sell only those securities it owns and will do so
      only with the intention of actually delivering the securities. The use of
      forward commitments enables a Fund to hedge against anticipated changes in
      interest rates and prices. In a forward sale, a Fund does not participate
      in gains or losses on the security occurring after the commitment date. A
      Fund will direct State Street to place the securities in a separate
      account. Forward commitments to sell securities also involve a risk of
      loss if the seller fails to take delivery after the value of the
      securities has declined. Further risks involving forward commitments are
      discussed in the section "Risks of Futures, Options and Forward Currency
      Contracts," below.
          Government Intermediate, Investment Grade and Government Money Market
      each does not expect that purchases of forward commitments will at any
      time exceed, in the aggregate, 20% of its total assets.

      FUTURES AND OPTIONS TRANSACTIONS

GOVERNMENT INTERMEDIATE AND INVESTMENT GRADE:
          In an effort to protect against the effect of adverse changes in
      interest rates, a Fund may purchase and sell interest rate futures
      contracts and may purchase put options on interest rate futures contracts
      and debt securities (practices known as "hedging"). A futures contract is
      an agreement by a Fund to buy or sell securities at a specified date and
      price. The purchase of a put option on a futures contract allows a Fund,
      at its option, to enter into a particular futures contract to sell
      securities at any time up to the option's expiration date.
          A Fund may seek to enhance its income or hedge the portfolio by
      writing (selling) covered call options (i.e., a Fund will own the
      underlying instrument while the call is outstanding) and covered put
      options (i.e., a Fund will have cash or appropriate liquid securities in a
      segregated account in an amount not less than the exercise price while the
      put is outstanding).
          RESTRICTIONS: A Fund will not enter into any futures contracts or
      related options if the sum of the initial margin deposits on futures
      contracts or related options and premiums paid for related options the
      Fund has purchased would exceed 5% of that Fund's total assets. A Fund
      will not purchase futures contracts or related options if, as a result,
      more than 33-1/3% of that Fund's total assets would be so invested.

HIGH YIELD:
          The Fund may write (sell) or purchase put and call options on domestic
      and foreign securities, securities indices and foreign currencies. Call
      options written by the Fund give the holder the right to buy the
      underlying securities or currencies from the Fund at a fixed exercise
      price up to a stated expiration date, or in the case of certain options,
      on such date. Put options give the holder the right to sell the underlying
      securities or currencies to the Fund at a fixed exercise price up to a
      stated expiration date, or in the case of certain options, on such date.
          The Fund may also enter into options on the yield "spread" or yield
      differential between two fixed-income securities, a transaction referred
      to as a "yield curve" option, for hedging and non-hedging purposes.
          The Fund may purchase and sell futures contracts on foreign
      currencies, securities, or indices of securities, including indices of
      fixed-income securities which may become available for trading. The Fund
      may also purchase and write options on such futures contracts.

      RISKS OF FUTURES, OPTIONS AND FORWARD CURRENCY CONTRACTS
          Many options on debt securities are traded primarily on the
      over-the-counter ("OTC") market. OTC options differ from exchange-traded
      options in that the former are two-party contracts with price and other
      terms negotiated between buyer and seller and generally do not have as
      much market liquidity as exchange-traded options. Thus, when a Fund
      purchases an OTC option, it relies on the dealer from which it has
      purchased the option to make or take delivery of the securities underlying
      the option. Failure by the dealer to do so would result in the loss of the
      premium paid by a Fund as well as the loss of the expected benefit of the
      transaction. OTC options may be considered "illiquid securities" for
      purposes of the Funds' investment limitations.
          When a Fund purchases or sells a futures contract, the Fund is
      required to deposit with its custodian (or a broker, if legally permitted)
      a specified amount of cash or U.S. government securities

18

<PAGE>
      ("initial margin"). Each day the Fund pays or receives cash ("variation
      margin") equal to the daily change in value of the futures contract. The
      use by a Fund of futures contracts or commodities option positions for
      other than bona fide hedging purposes is restricted by government
      regulations. (See the Statement of Additional Information.) If a Fund
      writes an option or sells a futures contract and is not able to close out
      that position prior to settlement date, the Fund may be required to
      deliver cash or securities substantially in excess of these amounts.
   
          The use of options, futures and forward currency contracts involves
      certain investment risks and transaction costs to which a Fund might not
      be subject if it did not use such instruments. These risks include (1)
      dependence on the Adviser's ability to predict movements in the prices of
      individual securities, fluctuations in the general securities markets or
      in market sectors and movements in interest rates and currency markets;
      (2) imperfect correlation between movements in the price of options,
      futures contracts or options thereon, or forward currency contracts or
      options thereon and movements in the price of the securities or currencies
      hedged or used for cover; (3) the fact that skills and techniques needed
      to trade options, futures contracts and options thereon or to use forward
      currency contracts are different from those needed to select the
      securities in which the Fund invests; (4) lack of assurance that a liquid
      secondary market will exist for any particular option, futures contract or
      option thereon, or forward currency contract at any particular time which
      may result in unanticipated losses; (5) the possibility that the use of
      cover or segregation involving a large percentage of a Fund's assets could
      impede portfolio management or the Fund's ability to meet redemption
      requests or other short-term obligations; and (6) the fact that, although
      use of these instruments for hedging purposes can reduce the risk of loss,
      they can also reduce the opportunity for gain, or even result in losses,
      by offsetting favorable price movements in hedged instruments. The use of
      options for speculative purposes, i.e., to enhance income or to increase a
      Fund's exposure to a particular security or foreign currency, subjects the
      Fund to additional risk. The use of futures or forward currency contracts
      to hedge an anticipated purchase (other than a when-issued or delayed
      delivery purchase) also subjects a Fund to additional risk until the
      purchase is completed or the position is closed out.
    
          The Statement of Additional Information contains a more detailed
      description of futures, options and forward strategies.

      RESTRICTED AND ILLIQUID SECURITIES
          Restricted securities are securities subject to legal or contractual
      restrictions on their resale, such as private placements. Such
      restrictions might prevent the sale of restricted securities at a time
      when sale would otherwise be desirable. Repurchase agreements maturing in
      more than seven days are considered illiquid. Illiquid securities, defined
      as securities that cannot be sold within 7 days at approximately the price
      they are valued, may be difficult to value, and a Fund may have difficulty
      disposing of such securities promptly.
          RESTRICTIONS: No more than 15% of High Yield's net assets will be
      invested in securities which are deemed illiquid. No more than 10% of
      Government Intermediate's or Investment Grade's net assets will be
      invested in illiquid securities.

      LENDING
          Each Fund may loan its portfolio securities to qualified borrowers who
      deposit and maintain with the Fund cash collateral equal to at least 100%
      of the market value of the securities loaned.

      INTEREST RATE SWAPS (HIGH YIELD ONLY)
          The Fund may enter into interest rate swaps. An interest rate swap is
      an agreement under which two parties exchange interest rate obligations,
      one of which typically is an interest rate fixed until the maturity of the
      obligation, while the other typically is a rate which changes with the
      changes in some other rate, such as the prime rate or the London Interbank
      Offered Rate (LIBOR). Such swaps will be used when the Fund wishes to
      effectively convert a floating rate asset into a fixed rate asset, or vice
      versa.

      LOAN PARTICIPATIONS AND ASSIGNMENTS (HIGH YIELD ONLY)
          The Fund may also invest in "loan participations or assignments." In
      purchasing a loan participation or assignment, the Fund acquires some or
      all of the interest of a bank or other lending institution in a loan to a
      corporate borrower. Many such loans are secured and most impose
      restrictive covenants which must be met by the borrower and which are
      generally more stringent than the covenants available in publicly traded
      debt securities.

                                                                              19

<PAGE>
      However, interests in some loans may not be secured, and the Fund will be
      exposed to a risk of loss if the borrower defaults. Loan participations
      may also be purchased by the Fund when the borrowing company is already in
      default.
          In purchasing a loan participation, the Fund may have less protection
      under the federal securities laws than it has in purchasing traditional
      types of securities. The Fund's ability to assert its rights against the
      borrower will also depend on the particular terms of the loan agreement
      among the parties.
          RESTRICTIONS: Many of the interests in loans purchased by the Fund
      will be illiquid and therefore subject to the Fund's 15% limit on illiquid
      investments.

PORTFOLIO TURNOVER
   
          For the year ended December 31, 1997, Government Intermediate's
      portfolio turnover rate was 252%, Investment Grade's portfolio turnover
      rate was 259% and High Yield's portfolio turnover rate was 116%. Each Fund
      anticipates that its annual portfolio turnover rate may exceed 300%. The
      Funds may sell fixed-income securities and buy similar securities to
      obtain yield and take advantage of market anomalies, a practice which will
      increase the reported turnover rate of the Funds. A portfolio turnover
      rate in excess of 100% will involve correspondingly greater transaction
      costs which will be borne directly by a Fund. It may also increase the
      amount of net short-term capital gains, if any, realized by a Fund and
      thus may affect the tax treatment of distributions paid to shareholders
      because distributions of net short-term capital gains are taxable as
      ordinary income. Each Fund will take these possibilities into account as
      part of its investment strategy.
    

HOW YOU CAN INVEST IN THE FUNDS

   
          You may purchase Primary Shares of the Funds through a brokerage
      account with Legg Mason, with an affiliate that has an agreement with Legg
      Mason, or with an unaffiliated entity having an agreement with Legg Mason
      ("Financial Advisor or Service Provider"). Your Financial Advisor or
      Service Provider will be pleased to explain the shareholder services
      available from the Funds and answer any questions you may have.
    
   
          Documents available from your Financial Advisor or Service Provider
      should be completed if you invest in shares of the Funds through an
      Individual Retirement Account, Simplified Employee Pension Plan, Savings
      Incentive Match Plan for Employees or tax-qualified retirement plan
      (collectively referred to as "Retirement Plans"). Investors who are
      considering establishing a Retirement Plan may wish to consult their
      attorneys or other tax advisers with respect to individual tax questions.
      The option of investing in these accounts and plans through regular
      payroll deductions may be arranged with Legg Mason and your employer.
      Additional information with respect to these accounts and plans is
      available upon request from a Financial Advisor or Service Provider.
    
          Clients of certain institutions that maintain omnibus accounts with
      the Funds' transfer agent may obtain shares through those institutions.
      Such institutions may receive payments from the Funds' distributor for
      account servicing, and may receive payments from their clients for other
      services performed. Investors can purchase Fund shares from Legg Mason
      without receiving or paying for such other services.
   
          The minimum initial investment in Primary Shares for each Fund
      account, including investments made by exchange from other Legg Mason
      funds and investments in a Retirement Plan or similar plan, is $1,000, and
      the minimum investment for each purchase of additional shares is $100 for
      Government Intermediate, Investment Grade and High Yield and $500 for
      Government Money Market, except as noted below.
    
          Cash held in Legg Mason brokerage accounts of Fund shareholders may be
      invested in Government Money Market during regularly scheduled "sweeps" of
      such accounts made twice each month. (Brokerage accounts participating in
      the Premier Asset Management Account described on page 27 are swept daily
      for free credit balances of $100 or more and weekly for free credit
      balances of less than $100.) For purchases of shares through payroll
      deduction plans, a Fund's Future First Systematic Investment Plan and
      plans involving automatic payment of funds from financial institutions

20

<PAGE>
      or automatic investment of dividends from certain unit investment trusts,
      minimum initial and subsequent investments are lower. Each Fund may change
      these minimum amount requirements at its discretion. You should always
      furnish your shareholder account number when making additional purchases
      of shares.
          There are three ways you can invest in Primary Shares:

   
1. THROUGH YOUR FINANCIAL ADVISOR OR SERVICE PROVIDER
    
   
          Shares may be purchased through a Financial Advisor or Service
      Provider. A Financial Advisor or Service Provider will be pleased to open
      an account for you, explain to you the shareholder services available from
      the Funds and answer any questions you may have. After you have
      established an account, you can order shares from your Financial Advisor
      or Service Provider in person, by telephone or by mail.
    
          If you want to purchase shares by mail, send a check for $100 or more
      ($500 or more for Government Money Market), payable to:
          [insert complete Fund name]
          c/o Legg Mason Funds Processing
          P.O. Box 1476
          Baltimore, Maryland 21203-1476

2. THROUGH THE FUTURE FIRST SYSTEMATIC INVESTMENT PLAN
   
          You may also buy shares through the Future First Systematic Investment
      Plan. Under this plan, you may arrange for automatic monthly investments
      in the Fund of $50 or more by authorizing Boston Financial Data Services
      ("BFDS"), the Funds' transfer agent, to transfer funds each month from
      your Legg Mason account or from your checking account. Please contact a
      Financial Advisor or Service Provider for further information.
    

3. THROUGH AUTOMATIC INVESTMENTS
   
          Arrangements may be made with some employers and financial
      institutions, such as banks or credit unions, for regular automatic
      monthly investments of $50 or more in shares. In addition, it may be
      possible for dividends from certain unit investment trusts to be invested
      automatically in shares. Persons interested in establishing such automatic
      investment programs should contact the Funds through their Financial
      Advisor or Service Provider.
    
   
          In addition to the above, you may also use either of the following
      methods to invest in Government Money Market:
    

BY TELEPHONE OR WIRE TRANSFER OF FUNDS
   
          Once you have opened an account with the Fund, you may also purchase
      shares by telephone, using available cash balances in your Legg Mason or
      affiliated brokerage account, or by wire transfer of funds from your bank
      directly to Legg Mason. Please contact a Financial Advisor or Service
      Provider for further information. Wire transfers may be subject to a
      service charge by your bank.
    

   
          Primary Share purchases of Government Intermediate, Investment Grade
      or High Yield will be processed at the net asset value next determined
      after your Financial Advisor or Service Provider has received your order;
      payment must be made within three business days to Legg Mason. Orders for
      one of those Funds, received by your Financial Advisor or Service Provider
      before the close of regular trading on the New York Stock Exchange
      ("Exchange") (normally 4:00 p.m. Eastern time) ("close of the Exchange")
      on any day the Exchange is open, will be executed at the net asset value
      determined as of the close of the Exchange on that day. Orders for one of
      those Funds, received by your Financial Advisor or Service Provider after
      the close of the Exchange or on days the Exchange is closed, will be
      executed at the net asset value determined as of the close of the Exchange
      on the next day the Exchange is open.
    
   
          Shares of Government Money Market are issued at the net asset value
      next determined after receipt of a purchase order and payment in proper
      form. Many instruments in which the Fund invests must be paid for in
      immediately available money called "federal funds." Therefore, payments
      received from you for the purchase of shares in other than federal funds
      form will require conversion into federal funds before your purchase order
      may be executed. For checks, this normally will take two days but may take
      up to nine days. All checks are accepted subject to collection at full
      face value in federal funds and must be drawn in U.S. dollars on a
      domestic bank. If an order for shares of Government Money Market and
      payment in federal funds is received by your Financial Advisor or Service
      Provider prior to 12:00 noon, Eastern time, on any day that the Exchange
      is open,
    

                                                                              21

<PAGE>
   
      the shares will be purchased and become eligible to earn dividends on that
      day; if such an order is received at 12:00 noon or later, or on days the
      Exchange is closed, the shares will be purchased at the next determined
      net asset value and will earn dividends on the next day the Exchange is
      open. Purchases made by telephone from available cash balances in your
      Legg Mason or affiliated brokerage account or wire payments representing
      federal funds will normally be completed on the same or the next business
      day. See "How Net Asset Value is Determined," page 24.
    
   
          Each Fund reserves the right to reject any order for its shares or to
      suspend the offering of shares for a period of time. Some Service
      Providers may place other conditions on the purchase of shares. Consult
      their program literature for further information.
    
HOW YOUR SHAREHOLDER ACCOUNT IS MAINTAINED

   
          When you initially purchase shares, a shareholder account is
      automatically established for you. Any shares that you purchase or receive
      as a dividend or other distribution will be credited directly to your
      account at the time of purchase or receipt. Shares may not be held in, or
      transferred to, an account with any brokerage firm that does not have an
      agreement with Legg Mason. The Funds do not issue share certificates.
    

HOW YOU CAN REDEEM YOUR PRIMARY SHARES

THE FOLLOWING REDEMPTION INFORMATION APPLIES TO GOVERNMENT INTERMEDIATE,
INVESTMENT GRADE AND HIGH YIELD:
   
          There are two ways you can redeem your Primary Shares of Government
      Intermediate, Investment Grade or High Yield. First, you may give your
      Financial Advisor or Service Provider an order for repurchase of your
      shares. Please have the following information ready when you call: the
      name of the Fund, the number of shares (or dollar amount) to be redeemed
      and your shareholder account number. Second, you may send a written
      request for redemption to: [insert complete Fund name], c/o Legg Mason
      Funds Processing, P.O. Box 1476, Baltimore, Maryland 21203-1476.
    
   
          Requests for redemption in "good order," as described below, received
      by your Financial Advisor or Service Provider before the close of the
      Exchange on any day when the Exchange is open, will be transmitted to
      BFDS, transfer agent for the Funds, for redemption at the net asset value
      per share determined as of the close of the Exchange on that day. Requests
      for redemption received by your Financial Advisor or Service Provider
      after the close of the Exchange will be executed at the net asset value
      determined as of the close of the Exchange on its next trading day. A
      redemption request received by your Financial Advisor or Service Provider
      may be treated as a request for repurchase and, if it is accepted by Legg
      Mason, your shares will be purchased at the net asset value per share
      determined as of the next close of the Exchange.
    
   
          Proceeds from your redemption normally will settle in your brokerage
      account two business days after trade date. The proceeds of your
      redemption or repurchase may be more or less than your original cost. If
      the shares to be redeemed or repurchased were paid for by check (including
      certified or cashier's checks) within 10 business days of the redemption
      or repurchase request, the proceeds will not be disbursed unless the Fund
      can be reasonably assured that the check has been collected.
    
          A redemption request will be considered to be received in "good order"
      only if:
          1. You have indicated in writing the number of Primary Shares (or
      dollar amount) to be redeemed, the complete Fund name and your shareholder
      account number;
          2. The written request is signed by you and by any co-owner of the
      account with exactly the same name or names used in establishing the
      account;
          3. The written request is accompanied by any certificates representing
      the shares that have been issued to you, and you have endorsed the
      certificates for transfer or an accompanying stock power exactly as the
      name or names appear on the certificates; and
          4. The signatures on the written redemption request and on any
      certificates for your shares (or an accompanying stock power) have been
      guaranteed without qualification by a national bank, a state bank, a
      member firm of a principal stock exchange or other entity described in
      Rule 17Ad-15 under the Securities Exchange Act of 1934.

<PAGE>
THE FOLLOWING REDEMPTION INFORMATION APPLIES TO GOVERNMENT MONEY MARKET:
          All redemptions will be made in cash at the net asset value per share
      next determined after the receipt by the Fund of a redemption request in
      proper form either in writing or by telephone as described below. Requests
      for redemption received after 12:00 noon, Eastern time, will be executed
      on the next day the Exchange is open, at the net asset value next
      determined. However, payment of redemption proceeds for shares purchased
      by check and shares acquired through reinvestment of dividends on such
      shares may be delayed for up to 10 days after receipt of the check in
      order to allow time for the check to clear. Any of the following methods
      may be used to redeem shares of Government Money Market:

1. Redemption by Telephone
   
          Telephone redemptions may be made by calling your Financial Advisor or
      Service Provider. The minimum amount for telephone redemptions is $100
      unless you require a lesser amount to complete a transaction in your Legg
      Mason or other brokerage account. Proceeds of redemptions requested by
      telephone will be transmitted only to you. They may be transferred by mail
      or wire, at your direction (see below). Proceeds of redemptions authorized
      by telephone will be credited directly to your Legg Mason or other
      brokerage account the same day. Wire transfers of proceeds to you from
      your Legg Mason or other brokerage account will normally be transmitted
      the same day.
    
   
          To make a telephone redemption, you should call your Financial Advisor
      or Service Provider and provide your name, the Fund's name, your Fund
      account number and the number of shares or dollar amount you wish to
      redeem. In the event that you are unable to reach your Financial Advisor
      or Service Provider by telephone, you may make a redemption request by
      mail. There is no fee for telephone redemptions with the exception of wire
      redemptions by telephone, as described below.
    
   
          You may request by telephone that your shares be redeemed and the
      proceeds wired to your account at a commercial bank in the United States.
      In order to initiate a wire redemption by telephone, you must inform your
      Financial Advisor or Service Provider of the name and address of your bank
      and your bank account number. If your designated bank is not a member of
      the Federal Reserve System, the proceeds will be wired to a member bank
      that has a correspondent relationship with your bank. The failure of the
      member bank immediately to notify your bank of the wire transfer could
      delay the crediting of redemption proceeds to your bank. A fee for using
      the wire redemption service may be deducted by Legg Mason or its affiliate
      from the redemption proceeds that are wired to your bank.
    

2. Redemption by Check
   
          The Fund offers a free checkwriting service that permits you to write
      checks to anyone in amounts of $500 or more. The checks will be paid at
      the time they are received by BFDS for payment by redeeming the
      appropriate number of shares in your account; the shares will earn
      dividends until the check clears BFDS for payment. Please contact your
      Financial Advisor or Service Provider for further information regarding
      this service.
    

3. Redemption by Mail
   
          You may request the redemption of your shares by sending a letter
      signed by all of the registered owners of the account to: "Legg Mason U.S.
      Government Money Market Portfolio, c/o Legg Mason Funds Processing, P.O.
      Box 1476, Baltimore, Maryland 21203-1476." Any stock certificates issued
      for the shares must be surrendered at the same time. For your protection,
      certificates, if any, should be sent by registered mail. On all requests
      for the redemption of shares valued at $10,000 or more, or when the
      proceeds of the redemption are to be paid to someone other than you, your
      signature must have been guaranteed without qualification by a national
      bank, a state bank, a member firm of a principal stock exchange, or other
      entity described in Rule 17Ad-15 under the Securities Exchange Act of
      1934. Legg Mason, its affiliates or others may request further
      documentation from corporations, executors, partnerships, administrators,
      trustees or custodians. Checks normally will be mailed within three
      business days of receipt of a proper redemption request to your address of
      record or, in accordance with your written request, to some other person.
    

                                                                              23

4. Redemption to Pay for Securities Purchases at Legg Mason
          Legg Mason has established special redemption procedures for Fund
      shareholders who wish to purchase stocks, bonds or other securities at
      Legg Mason. You may place an order to buy securities through your Legg
      Mason or affiliated financial advisor and, in the absence of any
      indication that you wish to make payment in another manner, Fund shares
      will be redeemed on the settlement date for the amount due. Fund shares
      may also be redeemed by Legg Mason to cover debit balances in your
      brokerage account. Contact your Legg Mason or affiliated financial advisor
      for details.

FOR EACH FUND:
   
          Other supporting legal documents may be required from corporations or
      other organizations, fiduciaries or persons other than the shareholder of
      record making the request for redemption or repurchase. If you have a
      question concerning the redemption of shares, contact your Financial
      Advisor or Service Provider.
    
   
          The Funds will not be responsible for the authenticity of redemption
      instructions received by telephone, provided they follow reasonable
      procedures to identify the caller. The Funds may request identifying
      information from callers or employ identification numbers. The Funds may
      be liable for losses due to unauthorized or fraudulent instructions if
      they do not follow reasonable procedures. Telephone redemption privileges
      are available automatically to all shareholders unless certificates have
      been issued. Shareholders who do not wish to have telephone redemption
      privileges should call their Financial Advisor or Service Provider for
      further instructions.
    
   
          To redeem your Legg Mason Fund retirement account, a Distribution
      Request Form must be completed and returned to Legg Mason Client Services
      for processing. This form can be obtained through your Legg Mason or
      affiliated financial advisor or Legg Mason Client Services in Baltimore,
      Maryland. Upon receipt of your form, your shares will be redeemed at the
      net asset value per share determined as of the next close of the Exchange.
    
          To the extent permitted by law, each Fund reserves the right to take
      up to seven days to make payment upon redemption if, in the judgment of
      the Adviser, the respective Fund could be adversely affected by immediate
      payment. (The Statement of Additional Information describes several other
      circumstances in which the date of payment may be postponed or the right
      of redemption suspended.)
          Because of the relatively high cost of maintaining small accounts,
      each Fund may elect to close any account with a current value of less than
      $500 by redeeming all of the shares in the account and mailing the
      proceeds to you. However, the Funds will not redeem accounts that fall
      below $500 solely as a result of a reduction in net asset value per share.
      If a Fund elects to redeem the shares in your account, you will be
      notified that your account is below $500 and will be allowed 60 days in
      which to make an additional investment in order to avoid having your
      account closed.
   
          Some Service Providers may have other procedures for redemption,
      either in addition to or instead of those described above. Consult your
      Service Provider's literature for more information.
    
HOW NET ASSET VALUE IS DETERMINED

FOR GOVERNMENT INTERMEDIATE, INVESTMENT GRADE AND HIGH YIELD:
          Net asset value per Primary Share is determined daily, as of the close
      of the Exchange, on every day that the Exchange is open, by subtracting
      the liabilities attributable to Primary Shares from the total assets
      attributable to such shares and dividing the result by the number of
      Primary Shares outstanding. Securities owned by the Funds for which market
      quotations are readily available are valued at current market value. In
      the absence of readily available market quotations, securities are valued
      at fair value as determined by the Corporation's Board of Directors. With
      respect to High Yield, where a security is traded on more than one market,
      which may include foreign markets, the securities are generally valued on
      the market considered by the Adviser to be the primary market. Securities
      with remaining maturities of 60 days or less are valued at amortized cost.
      The Fund will value its foreign securities in U.S. dollars on the basis of
      the then-prevailing exchange rates.

FOR GOVERNMENT MONEY MARKET:
          Net asset value per Fund share is determined twice daily, as of 12:00
      noon, Eastern time, and the close of business of the Exchange, on every
      day that the Exchange is open, by subtracting the

24

<PAGE>
      Fund's liabilities from its total assets and dividing the result by the
      number of shares outstanding. The Fund attempts to maintain a per share
      net asset value of $1.00 by using the amortized cost method of valuation.
      The Fund cannot guarantee that net asset value will always remain at $1.00
      per share.

DIVIDENDS AND OTHER DISTRIBUTIONS

   
          Each Fund declares dividends to holders of Primary Shares out of its
      investment company taxable income attributable to those shares, which
      consists of net investment income, any net short-term capital gain and, in
      the case of High Yield, any net gains from certain foreign currency
      transactions. With respect to Government Intermediate, Investment Grade
      and Government Money Market, dividends from net investment income are
      declared daily and paid monthly. For High Yield, dividends from net
      investment income are declared and paid monthly. Shareholders of
      Government Intermediate, Investment Grade and High Yield begin to earn
      dividends on their Fund shares as of settlement date, which is normally
      the third business day after their orders are placed with their Financial
      Advisor or Service Provider. With respect to Government Intermediate,
      Investment Grade and High Yield, dividends from net short-term capital
      gain and distributions of substantially all net capital gain (the excess
      of net long-term capital gain over net short-term capital loss) and, in
      the case of High Yield, net realized gains from foreign currency
      transactions, generally are declared and paid after the end of the taxable
      year in which the gain is realized. A second distribution of net capital
      gain may be necessary in some years to avoid imposition of the excise tax
      described under the heading "Additional Tax Information" in the Statement
      of Additional Information. Since Government Money Market's policy is,
      under normal circumstances, to hold portfolio securities to maturity and
      to value portfolio securities at amortized cost, it does not expect to
      realize any capital gain or loss. If the Fund does realize any net
      short-term capital gains, it will distribute them at least once every 12
      months.
    
   
          Dividends and other distributions, if any, on Primary Shares of a Fund
      held in a Retirement Plan and by shareholders maintaining a Systematic
      Withdrawal Plan generally are reinvested in Primary Shares of that Fund on
      the payment dates. Other shareholders may elect to:
    
          1. Receive both dividends and other distributions in Primary Shares of
      the distributing Fund;
          2. Receive dividends in cash and other distributions in Primary Shares
      of the distributing Fund;
          3. Receive dividends in Primary Shares of the distributing Fund and
      other distributions in cash; or
          4. Receive both dividends and other distributions in cash.

   
          If a shareholder has elected to receive dividends and/or other
      distributions in cash and the postal or other delivery service is unable
      to deliver checks to the shareholder's address of record, such
      shareholder's distribution option will automatically be converted to
      having all dividends and other distributions reinvested in additional
      Primary shares. No interest will accrue on amounts represented by uncashed
      distribution or redemption checks.
    
   
          In certain cases, shareholders may reinvest dividends and other
      distributions in Primary Shares of another Legg Mason fund. Please contact
      your Financial Advisor or Service Provider for additional information
      about this option.
    
          If no election is made, both dividends and other distributions are
      credited to your account in Primary Shares of the distributing Fund at the
      net asset value of the shares determined as of the close of the Exchange
      on the reinvestment date. Shares received pursuant to any of the first
      three (reinvestment) elections above also are credited to your account at
      that net asset value. If you elect to receive dividends and/or other
      distributions in cash, you will be sent a check or will have your Legg
      Mason account credited after the payment date. You may elect at any time
      to change your option by notifying the applicable Fund in writing at:
      [insert complete Fund name], c/o Legg Mason Funds Processing, P.O. Box
      1476, Baltimore, Maryland 21203-1476. Your election must be received at
      least 10 days before the record date in order to be effective for
      dividends and other distributions paid to shareholders as of that date.

                                                                              25

<PAGE>
TAX TREATMENT OF DIVIDENDS AND OTHER DISTRIBUTIONS

          Each Fund intends to continue to qualify for treatment as a regulated
      investment company under the Code so that it will be relieved of federal
      income tax on that part of its investment company taxable income and net
      capital gain that is distributed to its shareholders.
   
          Dividends from a Fund's investment company taxable income (whether
      paid in cash or reinvested in Primary Shares) are taxable to its
      shareholders (other than Retirement Plans and other tax-exempt investors)
      as ordinary income to the extent of the Fund's earnings and profits.
      Distributions of a Fund's net capital gain (whether paid in cash or
      reinvested in Primary Shares), when designated as such, are taxable to
      those shareholders as long-term capital gain, regardless of how long they
      have held their Fund shares. Under the Taxpayer Relief Act of 1997 ("Tax
      Act"), different maximum tax rates apply to a noncorporate taxpayer's net
      capital gain depending on the holding period of the security and the
      taxpayer's marginal rate of federal income tax. The relevant holding
      period is determined by how long the Fund has held the portfolio security
      on which the gain was earned, not by how long you have held your Fund
      shares.
    
   
          Each Fund sends its shareholders a notice following the end of each
      calendar year specifying, among other things, the amounts of all dividends
      and other distributions paid (or deemed paid) during that year. The notice
      will tell you what portion of the capital gain falls into each of the
      different tax rate categories mentioned above.
    
   
          Each Fund is required to withhold 31% of all dividends, and each Fund
      other than Government Money Market is required to withhold 31% of all
      capital gain distributions and redemption proceeds, payable to any
      individuals and certain other noncorporate shareholders who do not provide
      the Fund with a certified taxpayer identification number. Each Fund also
      is required to withhold 31% of all dividends, and each Fund other than
      Government Money Market is required to withhold 31% of all capital gain
      distributions, payable to such shareholders who otherwise are subject to
      backup withholding.
    

FOR GOVERNMENT INTERMEDIATE, INVESTMENT GRADE AND HIGH YIELD:
   
          A redemption of Primary Shares may result in taxable gain or loss to
      the redeeming shareholder, depending on whether the redemption proceeds
      are more or less than the shareholder's adjusted basis for the redeemed
      shares. An exchange of Primary Shares of any Fund for shares of another
      Legg Mason fund generally will have similar tax consequences. See
      "Shareholder Services -- Exchange Privilege." If Fund shares are purchased
      within 30 days before or after redeeming at a loss other shares of the
      same Fund (regardless of class), all or part of that loss will not be
      deductible and instead will increase the basis of the newly purchased
      shares.
    
          A dividend or other distribution paid shortly after shares have been
      purchased, although in effect a return of investment, is subject to
      federal income tax. Accordingly, an investor should recognize that a
      purchase of Primary Shares immediately prior to the record date for a
      dividend or other distribution could cause the investor to incur tax
      liabilities and should not be made solely for the purpose of receiving the
      dividend or other distribution.

   
          The foregoing is only a summary of some of the important federal
      income tax considerations generally affecting each Fund and its
      shareholders; see the Statement of Additional Information for a further
      discussion. In addition to federal income tax, you may also be subject to
      state and local income taxes on distributions from the Funds, depending on
      the laws of your home state and locality, though the portion of the
      dividends paid by each Fund attributable to direct U.S. government
      obligations is not subject to state and local income taxes in most
      jurisdictions. Each Fund's annual notice to shareholders regarding the
      amount of dividends identifies this portion. Prospective shareholders are
      urged to consult their tax advisers with respect to the effects of this
      investment on their own tax situations.

      purchase shares of a Fund while they are participating in the Systematic
      Withdrawal Plan with respect to that Fund. Please contact your Financial
      Advisor or Service Provider for further information.

EXCHANGE PRIVILEGE
   
          As a Fund shareholder, you are entitled to exchange your Primary
      Shares of a Fund for Primary Shares of any of the Legg Mason funds,
      provided that such shares are eligible for sale in your state of
      residence.
    
   
          Investments by exchange into the Legg Mason funds sold without an
      initial sales charge are made at the per share net asset value determined
      on the same business day as redemption of the Fund shares you wish to
      exchange. Investments by exchange into the Legg Mason funds sold with an
      initial sales charge are made at the per share net asset value, plus the
      applicable sales charge, determined on the same business day as redemption
      of the Fund shares you wish to redeem; except that no sales charge will be
      imposed upon proceeds from the redemption of Fund shares to be exchanged
      that were originally purchased by exchange from a fund on which the same
      or higher initial sales charge previously was paid. There is no charge for
      the exchange privilege, but each Fund reserves the right to terminate or
      limit the exchange privilege of any shareholder who makes more than four
      exchanges from that Fund in one calendar year. To obtain further
      information concerning the exchange privilege and prospectuses of other
      Legg Mason funds, or to make an exchange, please contact your Financial
      Advisor or Service Provider. To effect an exchange by telephone, please
      call your Financial Advisor or Service Provider with the information
      described in the section "How You Can Redeem Your Primary Shares," page
      22. The other factors relating to telephone redemptions described in that
      section apply also to telephone exchanges. Please read the prospectus for
      the other fund(s) carefully before you invest by exchange. Each Fund
      reserves the right to modify or terminate the exchange privilege upon 60
      days' notice to shareholders.

           Some Service Providers may not offer all of the Legg Mason Funds for
      exchange.
    

THE CORPORATION'S BOARD OF DIRECTORS, MANAGER AND INVESTMENT ADVISER

BOARD OF DIRECTORS
          The business and affairs of each Fund are managed under the direction
      of the Corporation's Board of Directors.

                                                                              27

<PAGE>
   
MANAGEMENT AGREEMENTS
    
   
          Each Fund has a management agreement with LMFA which was approved by
      the Corporation's Board of Directors (each a "Management Agreement").
      Under the Management Agreements, LMFA is obligated to provide the Funds
      with investment management and administrative services, and to oversee the
      Funds' relationships with outside service providers, such as the
      custodian, transfer agent, accountants, and lawyers.
    
   
          For services under the Management Agreements, LMFA receives a fee from
      each Fund, calculated daily and payable monthly, at the following annual
      rates of its average daily net assets:
    

   
      Government Intermediate                          0.55%
      Investment Grade                                 0.60%
      High Yield                                       0.65%
      Government Money Market                          0.50%
    

   
          Because of fee waivers (see below) Government Intermediate paid a
      management fee of 0.34% and Investment Grade paid a management fee of
      0.21% during the fiscal year ended December 31, 1997.
    

   
ADVISORY AGREEMENTS
    
   
          LMFA has entered into an investment advisory agreement with Western
      Asset Management Company ("Western Asset") to provide investment advisory
      services to each Fund.
    
   
          Western Asset has the responsibility for making investment decisions
      and placing orders to buy or sell a particular security for each Fund in
      accordance with its investment objective, policies and limitations. Under
      each Advisory Agreement, Western Asset receives an advisory fee from LMFA
      (not the Funds), computed daily and payable monthly, at annual rates of
      each Fund's average daily net assets as follows:
    

   
      Government     0.20%, not to exceed the fee paid to
      Intermediate   LMFA
      Investment     0.24%, or 40% of the fee received by
      Grade          LMFA
      High Yield     0.50%, or 77% of the fee received by
                     LMFA
      Government     0.15%, or 30% of the fee received by
      Money Market   LMFA
    

   
FEE WAIVERS
    
   
          LMFA has agreed to waive its fees in any month to the extent a Fund's
      expenses related to Primary Shares (exclusive of taxes, interest,
      brokerage and extraordinary expenses) exceed during that month annual
      rates of that Fund's average daily net assets attributable to Primary
      Shares as follows:
    

   
      Government     1.00% until May 1, 1999 or when the
      Intermediate   Fund reaches net assets of $400
                     million
      Investment     1.00% until May 1, 1999 or when the
      Grade          Fund reaches net assets of $150
                     million.
    


   
    
   
          These agreements are voluntary and may or may not be renewed by LMFA.
      Waiver by LMFA reduces a Fund's expenses and increases its yield and total
      return.
    

   
EXPENSE RATIOS
    
   
          For the year ended December 31, 1997, the ratio of each Fund's
      expenses to its average net assets (after application of any fee waivers)
      was:
    

   
      Government Intermediate                          1.00%
      Investment Grade                                 1.00%
      High Yield                                       1.30%
      Government Money Market                          0.75%
    

   
LMFA
    
   
          LMFA acts as investment adviser or manager to seventeen investment
      company portfolios which had aggregate assets under management of over
      $11.2 billion as of March 31, 1998. LMFA's address is 100 Light Street,
      Baltimore, Maryland 21202.
    
   
          Like other mutual funds, financial and business organizations around
      the world, the Funds could be adversely affected if the computer systems
      used by LMFA and other service providers do not properly process and
      calculate date-related information and data from and after January 1,
      2000. This is commonly known as the "Year 2000 Problem." LMFA is taking
      steps that it believes are reasonably designed to address the Year 2000
    

28

<PAGE>
   
      Problem with respect to the computer system that it uses and to obtain
      assurances that comparable steps are being taken by the Funds' other,
      major service providers. At this time, however, there can be no assurance
      that these steps will be sufficient to avoid any adverse impact on the
      Funds.
    

   
WESTERN ASSET
    
   
          Western Asset renders investment advice to fifteen open-end investment
      companies and one closed-end investment company, which together had
      aggregate assets under management of approximately $5.2 billion as of
      March 31, 1998. Western Asset also renders investment advice to private
      accounts with fixed income assets under management of approximately $33.7
      billion as of that date. The address of Western Asset is 117 East Colorado
      Boulevard, Pasadena, California 91105.
    
   
          Western Asset has managed fixed income portfolios continuously since
      its founding in 1971, and has focused exclusively on such accounts since
      1984. In managing fixed-income portfolios, Western Asset first studies the
      range of factors that influence interest rates and develops a long-term
      interest rate forecast. It then allocates available funds to those sectors
      of the market (for example, government, corporate, or mortgage-backed
      securities), which it considers most attractive. Then it selects the
      specific issues which it believes represent the best values. All three
      decisions are integral parts of the Adviser's portfolio management process
      and contribute to its performance record.
    

   
PORTFOLIO MANAGEMENT
    
   
          An investment committee has been responsible for the day-to-day
      management of each Fund since its inception.
    

THE FUNDS' DISTRIBUTOR

          Legg Mason is the distributor of the Funds' shares pursuant to
      separate Underwriting Agreements with each Fund. The Underwriting
      Agreements obligate Legg Mason to pay certain expenses in connection with
      the offering of shares of each Fund, including any compensation to its
      financial advisors, the printing and distribution of prospectuses,
      statements of additional information and periodic reports used in
      connection with the offering to prospective investors, after the
      prospectuses, statements of additional information and reports have been
      prepared, set in type and mailed to existing shareholders at the Fund's
      expense, and for any supplementary sales literature and advertising costs.
          The Board of Directors of the Corporation has adopted Distribution and
      Shareholder Services Plans (each a "Plan") pursuant to Rule 12b-1 under
      the Investment Company Act of 1940 ("1940 Act") for each Fund. The Plans
      provide that as compensation for Legg Mason's ongoing services to
      investors in Primary Shares and its activities and expenses related to the
      sale and distribution of Primary Shares, Government Intermediate,
      Investment Grade and High Yield each pay Legg Mason, from the assets
      attributable to Primary Shares, an annual distribution fee and an annual
      service fee, each of which is equal to 0.25% of that Fund's average daily
      net assets. With respect to Government Money Market, Legg Mason may
      receive payments at an annual rate of up to 0.20% of its average daily net
      assets. However, Legg Mason has agreed that it will not request payment of
      more than 0.10% annually from the Fund during the first two years
      following implementation of the Plan. Effective January 10, 1997,
      Government Money Market began compensating Legg Mason for distribution
      costs and services at this 0.10% annual rate. The distribution fee and the
      service fee are computed daily and paid monthly. The fees received by Legg
      Mason during any year may be more or less than its costs of providing
      distribution and shareholder services for Primary Shares. The offering of
      shares normally is continuous.
   
          Legg Mason may enter into agreements with unaffiliated dealers to
      sell Primary Shares of each Fund. Legg Mason pays such dealers up to
      90% of the distribution and shareholder service fees that it receives
      from a Fund with respect to shares sold by the dealers.
    
          NASD rules limit the amount of annual distribution and service fees
      that may be paid by mutual funds and impose a ceiling on the cumulative
      distribution fees paid. Each Fund's Plan complies with those rules.
   
          Legg Mason is a wholly owned subsidiary of Legg Mason, Inc., which is
      also the parent of the Manager and Adviser. Legg Mason receives a fee from
      BFDS for assisting it with its transfer agent and shareholder servicing
      functions; for the year ended December 31, 1997, Legg Mason received
      $41,000, $14,000, $45,000 and $83,000 for performing such services in
      connection with Government
    

                                                                              29

DESCRIPTION OF THE CORPORATION AND ITS SHARES
          The Corporation is a diversified open-end investment company which was
      incorporated in Maryland on April 28, 1987. The Articles of Incorporation
      of the Corporation permit the Board of Directors to create additional
      series (or portfolios), each of which may issue separate classes of
      shares. There are currently four portfolios of the Corporation. While
      additional series may be created in the future, there is no intention at
      this time to form any particular additional series.
          The Corporation has authorized one billion shares of common stock, par
      value $0.001 per share. Government Intermediate, Investment Grade and High
      Yield currently offer two Classes of Shares -- Class A (known as "Primary
      Shares") and Class Y (known as "Navigator Shares"). The two Classes
      represent interests in the same pool of assets. A separate vote is taken
      by a Class of Shares of a Fund if a matter affects just that Class of
      Shares. Each Class of Shares may bear certain differing Class-specific
      expenses. Salespersons and others entitled to receive compensation for
      selling or servicing Fund shares may receive more with respect to one
      Class than another.
   
          Investors may obtain more information concerning the Navigator Class
      from their Financial Advisor or any person making available to them shares
      of the Primary Class, or by calling 1-800-822-5544.
    
   
          The Board of Directors of the Corporation does not anticipate that
      there will be any conflicts among the interests of the holders of the
      different Classes of Fund shares. On an ongoing basis, the Board will
      consider whether any such conflict exists and, if so, take appropriate
      action.
    
          Shareholders of the Funds are entitled to one vote per share and
      fractional votes for fractional shares held. Voting rights are not
      cumulative. All shares of the Funds are fully paid and nonassessable and
      have no preemptive or conversion rights.
   
          Shareholders' meetings will not be held except where the 1940 Act
      requires a shareholder vote on certain matters (including the election of
      directors, approval of an advisory contract, and approval of a plan of
      distribution pursuant to Rule 12b-1). The Corporation will call a special
      meeting of the shareholders at the request of 10% or more of the shares
      entitled to vote; shareholders wishing to call such a meeting should
      submit a written request to their respective Fund at 100 Light Street,
      Baltimore, Maryland 21202, stating the purpose of the proposed meeting and
      the matters to be acted upon.
    
          Each Fund acknowledges that it is solely responsible for the
      information or any lack of information about it in this joint Prospectus
      and in the joint Statement of Additional Information, and no other Fund is
      responsible therefor. There is a possibility that one Fund might be deemed
      liable for misstatements or omissions regarding another Fund in this
      Prospectus or in the joint Statement of Additional Information; however,
      the Funds deem this possibility slight.

APPENDIX

RATINGS OF SECURITIES

DESCRIPTION OF MOODY'S INVESTORS SERVICE, INC. ("MOODY'S") CORPORATE BOND
RATINGS:
          Aaa -- Bonds which are rated Aaa are judged to be of the best quality.
      They carry the smallest degree of investment risk and are generally
      referred to as "gilt edge". Interest payments are protected by a large or
      exceptionally stable margin and principal is secure. While the various
      protective elements are likely to change, such changes as can be
      visualized are most unlikely to impair the fundamentally strong position
      of such issues.
          Aa -- Bonds which are rated Aa are judged to be of high quality by all
      standards. Together with the Aaa group they comprise what are generally
      known as high-grade bonds. They are rated lower than the best bonds
      because margins of protection may not be as large as in Aaa securities or
      fluctuation of protective elements may be of greater amplitude or there
      may be other elements present which make the long-term risks appear
      somewhat larger than the Aaa securities.
          A -- Bonds which are rated A possess many favorable investment
      attributes and are to be considered upper-medium-grade obligations.
      Factors giving security to principal and interest are considered adequate,
      but elements may be present which suggest a susceptibility to impairment
      some time in the future.
          Baa -- Bonds which are rated Baa are considered medium-grade
      obligations, (i.e., they are neither highly protected nor poorly secured).
      Interest payments and principal security appear adequate for the present
      but certain protective elements may be lacking or may be
      characteristically unreliable over any great length of time. Such bonds
      lack outstanding investment characteristics and in fact have speculative
      characteristics as well.
          Ba -- Bonds which are rated Ba are judged to have speculative
      elements; their future cannot be considered well-assured. Often the
      protection of interest and principal payments may be very moderate, and
      thereby not well safeguarded during both good and bad times over the
      future. Uncertainty of position characterizes bonds in this class.
          B -- Bonds which are rated B generally lack characteristics of the
      desirable investment. Assurance of interest and principal payments or
      maintenance of other terms of the contract over any long period of time
      may be small.
          Caa -- Bonds which are rated Caa are of poor standing and may be in
      default or there may be present elements of danger with respect to
      principal or interest.
          Ca -- Bonds which are rated Ca represent obligations which are
      speculative in a high degree and are often in default or have other marked
      shortcomings.
          C -- Bonds which are rated C are the lowest rated class of bonds and
      can be regarded as having extremely poor prospects of ever attaining any
      real investment standing.

DESCRIPTION OF STANDARD & POOR'S ("S&P") CORPORATE BOND RATINGS:
          AAA -- This is the highest rating assigned by S&P to an obligation.
      Capacity to pay interest and repay principal is extremely strong.
          AA -- Bonds rated AA have a very strong capacity to pay interest and
      repay principal and differ from the higher rated issues only in small
      degree.
          A -- Bonds rated A have a strong capacity to pay interest and repay
      principal, although they are somewhat more susceptible to the adverse
      effects of changes in circumstances and economic conditions than debt in
      higher categories.
          BBB -- Bonds rated BBB are regarded as having an adequate capacity to
      pay principal and interest. Whereas they normally exhibit adequate
      protection parameters, adverse economic conditions or changing
      circumstances are more likely to lead to a weakened capacity to pay
      interest and repay principal for bonds in this category than for bonds in
      higher rated categories.
          BB, B, CCC, CC -- Bonds rated BB, B, CCC and CC are regarded, on
      balance, as predominately speculative with respect to the issuer's
      capacity to pay interest and repay principal in accordance with the terms
      of the obligation. BB indicates the lowest degree of speculation and CC
      the highest degree of speculation. While such bonds will likely have some
      quality and protective characteristics, these are outweighed by large

                                                                              31

<PAGE>
      uncertainties or major risk exposures to adverse conditions.
          C -- Bonds on which no interest is being paid are rated C.
          D -- Bonds rated D are in payment default and payment of interest
      and/or repayment of principal is in arrears.

DESCRIPTION OF MOODY'S PREFERRED STOCK RATINGS:
          aaa -- An issue which is rated "aaa" is considered to be a top-quality
      preferred stock. This rating indicates good asset protection and the least
      risk of dividend impairment within the universe of preferred stocks.
          aa -- An issue which is rated "aa" is considered a high-grade
      preferred stock. This rating indicates that there is a reasonable
      assurance that earnings and asset protection will remain relatively
      well-maintained in the foreseeable future.
          a -- An issue which is rated "a" is considered to be an
      upper-medium-grade preferred stock. While risks are judged to be somewhat
      greater than in the "aaa" and "aa" classification, earnings and asset
      protection are, nevertheless, expected to be maintained at adequate
      levels.
          baa -- An issue which is rated "baa" is considered to be a
      medium-grade preferred stock, neither highly protected nor poorly secured.
      Earnings and asset protection appear adequate at present but may be
      questionable over any great length of time.
          ba -- An issue which is rated "ba" is considered to have speculative
      elements and its future cannot be considered well assured. Earnings and
      asset protection may be very moderate and not well safeguarded during
      adverse periods. Uncertainty of position characterizes preferred stocks in
      this class.
          b -- An issue which is rated "b" generally lacks the characteristics
      of a desirable investment. Assurance of dividend payments and maintenance
      of other terms of the issue over any long period of time may be small.
          caa -- An issue which is rated "caa" is likely to be in arrears on
      dividend payments. This rating designation does not purport to indicate
      the future status of payments.
          ca -- An issue which is rated "ca" is speculative in a high degree and
      is likely to be in arrears on dividends with little likelihood of eventual
      payments.
          c -- This is the lowest rated class of preferred stock or preference
      stock. Issues so rated can be regarded as having extremely poor prospects
      of ever attaining any real investment standing.

NAVIGATOR TAXABLE INCOME FUNDS
PROSPECTUS
DATED: MAY 1, 1998
     LEGG MASON U.S. GOVERNMENT INTERMEDIATE-TERM PORTFOLIO
     LEGG MASON INVESTMENT GRADE INCOME PORTFOLIO
     LEGG MASON HIGH YIELD PORTFOLIO

   
    Shares of Navigator U.S. Government Intermediate-Term Portfolio, Navigator
Investment Grade Income Portfolio and Navigator High Yield Portfolio
(collectively referred to as "Navigator Shares") represent separate classes
("Navigator Classes") of interest in the Legg Mason U.S. Government
Intermediate-Term Portfolio ("Government Intermediate"), Legg Mason Investment
Grade Income Portfolio ("Investment Grade") and Legg Mason High Yield Portfolio
("High Yield"), respectively. Government Intermediate, Investment Grade and High
Yield (each a "Fund") are separate, professionally managed portfolios of Legg
Mason Income Trust, Inc. ("Corporation"), a diversified open-end management
investment company.
    

    MUTUAL FUND SHARES ARE NOT DEPOSITS OR OBLIGATIONS OF, OR GUARANTEED OR
ENDORSED BY, ANY BANK OR OTHER DEPOSITORY INSTITUTION. SHARES ARE NOT INSURED BY
THE FDIC, THE FEDERAL RESERVE BOARD, OR ANY OTHER AGENCY, AND ARE SUBJECT TO
INVESTMENT RISK, INCLUDING THE POSSIBLE LOSS OF THE PRINCIPAL AMOUNT INVESTED.

    This Prospectus sets forth concisely the information about the Funds that a
prospective investor ought to know before investing. It should be retained for
future reference. A Statement of Additional Information about the Funds dated
May 1, 1998 has been filed with the Securities and Exchange Commission ("SEC")
and, as amended or supplemented from time to time, is incorporated herein by
reference. The Statement of Additional Information is available without charge
upon request from the Funds' distributor, Legg Mason Wood Walker, Incorporated
("Legg Mason") (address and telephone numbers listed below).

   
    THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION NOR HAS THE SECURITIES AND EXCHANGE COMMISSION PASSED UPON
THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY
IS A CRIMINAL OFFENSE.
    

    GOVERNMENT INTERMEDIATE seeks to provide investors with high current income
consistent with prudent investment risk and liquidity needs. In seeking to
achieve the Fund's objective, the Corporation's investment adviser, Western
Asset Management Company ("Adviser"), under normal circumstances, invests at
least 75% of the Fund's total assets in obligations issued or guaranteed by the
U.S. Government, its agencies or instrumentalities, or instruments secured by
such securities. The Fund expects to maintain an average dollar-weighted
maturity of between three and ten years.

    INVESTMENT GRADE seeks to provide investors with a high level of current
income through investment in a diversified portfolio of debt securities. In
seeking to achieve the Fund's objective, the Adviser, under normal
circumstances, invests primarily in fixed-income securities which the Adviser
considers to be of investment grade, i.e., securities rated within the four
highest grades by Moody's Investors Service, Inc. ("Moody's) or Standard &
Poor's ("S&P"), securities comparably rated by another nationally recognized
statistical rating organization ("NRSRO"), or unrated securities judged by the
Adviser to be of comparable quality.

    HIGH YIELD seeks to provide investors with a high level of current income.
As a secondary objective, the Fund seeks capital appreciation. IN SEEKING TO
ACHIEVE THE FUND'S OBJECTIVES, THE ADVISER, UNDER NORMAL CIRCUMSTANCES, INVESTS
AT LEAST 65% OF THE FUND'S TOTAL ASSETS IN HIGH YIELD, FIXED-INCOME SECURITIES
(COMMONLY KNOWN AS "JUNK BONDS"); THAT IS, INCOME-PRODUCING DEBT SECURITIES AND
PREFERRED STOCKS OF ALL TYPES, INCLUDING CORPORATE DEBT SECURITIES AND PREFERRED
STOCK. IN ADDITION TO OTHER RISKS, THESE BONDS ARE SUBJECT TO GREATER
FLUCTUATIONS IN VALUE AND RISK OF LOSS OF INCOME AND PRINCIPAL DUE TO DEFAULT BY
THE ISSUER THAN ARE HIGHER-RATED BONDS; THEREFORE, INVESTORS SHOULD CAREFULLY
ASSESS THE RISKS ASSOCIATED WITH AN INVESTMENT IN THIS FUND. SEE "INVESTMENT
TECHNIQUES AND RISKS" ON PAGE 9. The Fund may invest up to 25% of its total
assets in securities restricted as to their disposition, which may include
securities for which the Fund believes there is a liquid market. No more than
15% of the Fund's net assets will be invested in securities deemed by the Fund
to be illiquid. An investment in the Fund does not constitute a complete
investment program and is not appropriate for persons unwilling to assume a high
degree of risk.

    The Navigator Classes of Shares, described in this Prospectus, are currently
offered for sale only to institutional clients of the Fairfield Group, Inc.
("Fairfield") for investment of their own monies and monies for which they act
in a fiduciary capacity, to clients of Legg Mason Trust Company ("Trust
Company") for which Trust Company exercises discretionary investment management
responsibility (such institutional investors are referred to collectively as
"Institutional Clients" and

<PAGE>
accounts of the customers with such Institutional Clients ("Customers") are
referred to collectively as "Customer Accounts"), to qualified retirement plans
managed on a discretionary basis and having net assets of at least $200 million,
to clients of Bartlett & Co. ("Bartlett") who, as of December 19, 1996, were
shareholders of Bartlett Short Term Bond Fund or Bartlett Fixed Income Fund and
for whom Bartlett acts as an ERISA fiduciary, and to any qualified retirement
plan of Legg Mason, Inc. or of any of its affiliates. Navigator Shares may not
be purchased by individuals directly, but Institutional Clients may purchase
shares for Customer Accounts maintained for individuals.

    Navigator Shares are sold and redeemed without any purchase or redemption
charge imposed by the Funds, although Institutional Clients may charge their
Customer Accounts for services provided in connection with the purchase or
redemption of shares. See "How to Purchase and Redeem Shares." Each Fund pays
management fees to Legg Mason Fund Adviser, Inc., but Navigator Classes pay no
distribution fees.

     EXPENSES

   
    The purpose of the following tables is to assist an investor in
understanding the various costs and expenses that an investor in Navigator
Shares of a Fund will bear directly or indirectly. The expenses and fees set
forth in the table are based on average net assets and annual Fund operating
expenses of the Navigator Classes of Government Intermediate and Investment
Grade for the year ended December 31, 1997 and are based on estimated expenses
for the initial period of operations of the Navigator Class of High Yield.

(A) After fee waivers. LMFA has agreed to continue to waive fees to the extent
    the expenses attributable to Navigator Shares (exclusive of taxes, interest,
    brokerage and extraordinary expenses) exceed during any month an annual rate
    of 0.50% of average daily net assets attributable to Navigator Shares for
    such month, until the earlier of May 1, 1999, or, with respect to Government
    Intermediate, until its net assets reach $400 million and, with respect to
    Investment Grade, until its net assets reach $150 million, and unless
    extended will terminate on that date. In the absence of such waivers, the
    expected management fees, other expenses and total operating expenses would
    be as follows: for Government Intermediate, 0.55%, 0.11% and 0.66%,
    respectively; and for Investment Grade, 0.60%, 0.22% and 0.82%,
    respectively.

EXAMPLE
    The following example illustrates the expenses that you would pay on a
$1,000 investment in Navigator Shares over various time periods assuming (1) a
5% annual rate of return and (2) full redemption at the end of each time period.
The Funds charge no redemption fees of any kind.

    This example assumes that all dividends and other distributions are
reinvested and that the percentage amounts listed under Annual Fund Operating
Expenses remain the same over the time periods shown. The above tables and the
assumption in the example of a 5% annual return are required by regulations of
the SEC applicable to all mutual funds. THE ASSUMED 5% ANNUAL RETURN IS NOT A
PREDICTION OF AND DOES NOT REPRESENT THE PROJECTED OR ACTUAL PERFORMANCE OF
NAVIGATOR SHARES OF THE FUNDS. THE ABOVE TABLES AND EXAMPLE SHOULD NOT BE
CONSIDERED A REPRESENTATION OF PAST OR FUTURE EXPENSES. ACTUAL EXPENSES MAY BE
GREATER OR LESS THAN THOSE SHOWN. The actual expenses attributed to Navigator
Shares will depend upon, among other things, the level of average net assets,
the levels of sales and redemptions of shares, whether LMFA waives its fees, and
the extent to which Navigator Shares incur variable expenses, such as transfer
agency costs.

     PERFORMANCE INFORMATION

    From time to time each Fund may quote the TOTAL RETURN of each class of
shares in advertisements or in reports or other communications to shareholders.
A mutual fund's total return is a measurement of the overall change in value,
including changes in share price and assuming reinvestment of dividends and
capital gain distributions, of an investment in the fund. CUMULATIVE TOTAL
RETURN shows the fund's performance over a specific period of time. AVERAGE
ANNUAL TOTAL RETURN is the average annual compounded return that would have
produced the same cumulative total return if the fund's performance had been
constant over the entire period. Performance figures reflect past performance
only and are not intended to indicate future performance. Average annual returns
tend to smooth out variations in the fund's return, so they differ from actual
year-by-year results.
    Total returns as of December 31, 1997 were as follows:

    No adjustment has been made for any income taxes payable by shareholders.
The investment return of each Fund will fluctuate. The principal value of an
investment in each Fund will fluctuate so that an investor's shares, when
redeemed, may be worth more or less than their original cost. Returns of
Government Intermediate and Investment Grade would have been lower if the
Manager had not waived certain fees and expenses during the fiscal years 1987
through 1997. Because Navigator Shares have lower total expenses, they will
generally have a higher return than Primary Shares.
    Each Fund also may advertise its yield or effective yield. Yield reflects
net investment income per share (as defined by applicable SEC regulations) over
a 30-day (or one-month) period, expressed as an annualized percentage of net
asset value at the end of the period. The effective yield, although calculated
similarly, will be slightly higher than the yield because it assumes that income
earned from the investment is reinvested (i.e., the compounding effect of
reinvestment). Yield computations differ from other accounting methods and
therefore may differ from dividends actually paid or reported net income.
    Further information about each Fund's performance is contained in the
Corporation's annual report to shareholders, which may be obtained without
charge by calling a financial advisor at Fairfield, Legg Mason or Legg Mason's
Funds Marketing Department at 800-822-5544.

                                                                               5

      INVESTMENT OBJECTIVES AND POLICIES

          Each Fund's investment objective may not be changed without
      shareholder approval; however, except as otherwise noted, the investment
      policies of each Fund described below may be changed by the Corporation's
      Board of Directors without a shareholder vote. There can be no assurance
      that any Fund will achieve its investment objective.

          GOVERNMENT INTERMEDIATE'S investment objective is to provide investors
      with high current income consistent with prudent investment risk and
      liquidity needs. At least 75% of the Fund's total assets are, under normal
      circumstances, invested in U.S. government securities or instruments
      secured by such securities, including repurchase agreements. The Fund
      expects to maintain an average dollar-weighted maturity of between three
      and ten years. In the case of obligations not backed by the full faith and
      credit of the United States, the Fund must look principally to the agency
      or instrumentality issuing or guaranteeing the obligation for ultimate
      repayment and may not be able to assert a claim against the United States
      itself in the event the agency or instrumentality does not meet its
      commitments. The U.S. Government does not guarantee the market value of
      the Fund's investments or the market value or yield of the Fund's shares,
      all of which will fluctuate as market interest rates change. Investments
      in mortgage-related securities issued by governmental or
      government-related entities, as described on page 11, will be included in
      the 75% limitation.
          The balance of the Fund, up to 25% of its total assets, normally is
      invested in cash, commercial paper and investment grade debt securities
      rated within one of the four highest grades assigned by S&P (AAA, AA, A or
      BBB) or Moody's (Aaa, Aa, A or Baa), securities comparably rated by
      another NRSRO, or unrated securities judged by the Adviser to be of
      comparable quality. Debt securities rated Baa are deemed by Moody's to
      have speculative characteristics; changes in economic conditions or other
      circumstances are more likely to lead to a weakened capacity for the
      issuers of such securities to make principal and interest payments than is
      the case for high-grade debt securities. A further description of Moody's
      and S&P's ratings is included in the Appendix to this Prospectus.

          INVESTMENT GRADE'S investment objective is to provide investors with a
      high level of current income through investment in a diversified portfolio
      of debt securities. In seeking to achieve its objective, the Fund invests
      primarily in fixed-income securities which the Adviser considers to be of
      investment grade, of which some may be privately placed and some may have
      equity features.
          In pursuing its objective, under normal circumstances, the Fund
      invests at least 75% of its total assets in the following types of
      investment grade fixed-income securities:

          (1) debt securities which are rated at the time of purchase within the
      four highest grades assigned by Moody's or S&P, or, if unrated by Moody's
      or S&P, judged by the Adviser to be of comparable quality.
          (2) securities of, or guaranteed by, the U.S. government, its agencies
      or instrumentalities.
          (3) commercial paper and other money market instruments which are
      rated A-1 or A-2 by S&P or Prime-1 or Prime-2 by Moody's at the date of
      investment, or if unrated by Moody's or S&P, judged by the Adviser to have
      investment quality comparable to securities which may be purchased under
      item (1); bank certificates of deposit; and bankers' acceptances.
          (4) preferred stocks (including step down preferred securities), rated
      no lower than Baa by Moody's or, if unrated by Moody's, judged by the
      Adviser to be of comparable quality.

          The remainder of the Fund's assets, not in excess of 25% of its total
      assets, may be invested in: (1) debt securities of issuers which are rated
      at the time of purchase below Moody's and S&P's four highest grades, but
      rated B or better by Moody's or S&P, or if unrated by Moody's or S&P,
      judged by the Adviser to be of comparable quality; and (2) securities
      which may be convertible into or exchangeable for, or carry warrants to
      purchase, common stock or other equity interests (such securities may
      offer attractive income opportunities, and the debt securities of certain
      issuers may not be available without such features).
          The Fund currently invests in debt securities with maturities ranging
      from short-term (including overnight) up to forty years and anticipates
      that it will continue to do so. The Fund expects to maintain its portfolio
      of securities so as to have an average dollar-weighted maturity of between
      five and twenty years.

          HIGH YIELD'S investment objective is to provide investors with a high
      level of current income. As a secondary objective, the Fund seeks capital
      appreciation. In seeking to achieve the Fund's objectives, the Adviser,
      under normal circum-

6

<PAGE>
      stances, invests at least 65% of the Fund's total assets in high yield,
      fixed-income securities, that is, income producing debt securities and
      preferred stocks of all types, including corporate debt securities and
      preferred stock, convertible securities, zero coupon securities, deferred
      interest securities, mortgage-backed securities and asset-backed
      securities. The Fund's remaining assets may be held in cash or money
      market instruments, or invested in common stocks and other equity
      securities when these types of investments are consistent with the
      objectives of the Fund or are acquired as part of a unit consisting of a
      combination of fixed-income securities and equity investments. Such
      remaining assets may also be invested in fixed-income securities rated
      above BBB by S&P or Baa by Moody's, securities comparably rated by another
      NRSRO, or unrated securities deemed by the Adviser to be of equivalent
      quality. Moreover, the Fund may hold cash or money market instruments
      without limit for temporary defensive purposes or pending investment.
      Current yield is the primary consideration used by the Adviser in the
      selection of portfolio securities, although consideration may also be
      given to the potential for capital appreciation.
          Higher yields are generally available from securities rated BBB or
      lower by S&P, Baa or lower by Moody's, securities comparably rated by
      another NRSRO, or unrated securities of equivalent quality, and the Fund
      may invest all or a substantial portion of its assets in such securities.
      Debt securities rated below investment grade (i.e., below BBB/Baa) are
      deemed by these agencies to be predominantly speculative with respect to
      the issuer's capacity to pay interest and repay principal and may involve
      major risk or exposure to adverse conditions. The Fund may invest in
      securities rated as low as "C" by Moody's or "D" by S&P, which ratings
      indicate that the obligations are highly speculative and may be in default
      or in danger of default as to principal and interest. Ratings are only the
      opinions of the agencies issuing them and are not absolute guarantees as
      to quality. The Adviser does not rely solely on the ratings of rated
      securities in making investment decisions but also evaluates other
      economic and business factors affecting the issuer. The Appendix to this
      Prospectus describes Moody's and S&P's rating categories of securities in
      which the Fund may invest.
          Fixed-income securities in which the Fund may invest include preferred
      stocks and all types of debt obligations of both domestic and foreign
      issuers, commercial paper, and obligations issued or guaranteed by the
      U.S. Government, foreign governments or of any of their respective
      political subdivisions, agencies, or instrumentalities, including
      repurchase agreements secured by such instruments.
          The Fund may invest up to 25% of its total assets in private
      placements and securities which, though not registered at the time of
      their initial sale, are issued with registration rights. The Fund may also
      invest in securities traded pursuant to Rule 144A under the Securities Act
      of 1933. Rule 144A permits large institutions to trade certain securities
      even though they are not registered under that Act. Some of these
      securities may be deemed by the Adviser to be liquid. The Fund will not
      invest more than 5% of its total assets in any one issuer, except for
      issues of the U.S. Government, its agencies and instrumentalities or
      repurchase agreements collateralized by such securities; however, up to
      25% of the Fund's total assets may be invested in securities issued by
      Canadian provinces or by Crown Corporations whose obligations are
      guaranteed by either the Canadian federal government or a provincial
      government. No more than 25% of the Fund's total assets may be invested in
      issuers having their principal business activity in the same industry.

GENERAL
          The market value of the interest-bearing debt securities held by a
      Fund, and therefore the net asset value of Fund shares, is affected by
      changes in market interest rates. There is normally an inverse
      relationship between the market value of securities sensitive to
      prevailing interest rates and actual changes in interest rates; i.e., a
      decline in interest rates produces an increase in market value, while an
      increase in rates produces a decrease in market value. Moreover, the
      longer the remaining maturity of a security, the greater is the effect of
      interest rate changes on the market value of such a security. In addition,
      changes in the ability of an issuer to make payments of interest and
      principal and in the market's perception of an issuer's creditworthiness
      also affect the market value of the debt securities of that issuer.
          Certain of the mortgage-backed and other securities in which a Fund
      can invest pay interest at variable or floating rates. Variable rate
      instruments reset at specified intervals, while floating rate instruments
      reset whenever there is a change in a specified index rate. The more
      closely these changes reflect current market rates, the more likely the
      instrument will trade at a price close to its par value. Some instruments
      do not directly track the underlying index, but reset based on formulas
      that can produce an effect similar to lever-

                                                                               7

<PAGE>
      age; others may provide for interest payments that vary inversely with
      market rates. These instruments are regarded as "derivatives," and may
      vary significantly in market price when interest rates change.
          Each Fund has adopted certain fundamental investment limitations that,
      like its investment objective, may not be changed without the approval of
      its shareholders. A full description of these investment limitations is
      included in the Statement of Additional Information.

INVESTMENT TECHNIQUES AND RISKS
          The following investment techniques and risks apply to each of the
      Funds unless otherwise stated.

      Corporate Debt Securities
          Corporate debt securities may pay fixed or variable rates of interest,
      or interest at a rate contingent upon some other factor, such as the price
      of some commodity. These securities may be convertible into preferred or
      common equity, or may be bought as part of a unit containing common stock.
      In selecting corporate debt securities for a Fund, the Adviser reviews and
      monitors the creditworthiness of each issuer and issue. The Adviser also
      analyzes interest rate trends and specific developments which it believes
      may affect individual issuers.

      Callable Debt Securities
          A debt security may be callable, i.e., subject to redemption at the
      option of the issuer at a price established in the security's governing
      instrument. If a debt security held by a Fund is called for redemption,
      that Fund will be required to permit the issuer to redeem the security or
      sell it to a third party. Either of these actions could have an adverse
      effect on a Fund's ability to achieve its investment objectives.

      Risks of Lower-Rated Debt Securities
          Debt securities rated Baa and preferred stock rated Ba are deemed by
      Moody's to have speculative characteristics. Debt securities rated B by
      Moody's "generally lack characteristics of the desirable investment.
      Assurance of interest and principal payments or of maintenance of other
      terms of the contract over any long period of time may be small." S&P
      states that debt rated B "has a greater vulnerability to default but
      currently has the capacity to meet interest payments and principal
      repayments. Adverse business, financial or economic conditions will likely
      impair capacity or willingness to pay interest and repay principal."
          High yield bonds offer a higher yield to maturity than bonds with
      higher ratings, as compensation for holding an obligation that is subject
      to greater risk. The principal risks of high yield securities include: (i)
      limited liquidity and secondary market support, (ii) substantial market
      price volatility resulting from changes in prevailing interest rates,
      (iii) the fact that such obligations are often unsecured and are
      subordinated to the claims of banks and other senior lenders in bankruptcy
      proceedings, (iv) the operation of mandatory sinking fund or
      call/redemption provisions during periods of declining interest rates,
      whereby the holder might receive redemption proceeds at times when only
      lower-yielding securities are available for investment, (v) the
      possibility that earnings of the issuer may be insufficient to meet its
      debt service, (vi) the issuer's low creditworthiness and potential for
      insolvency during periods of rising interest rates and economic downturn,
      (vii) the fact that the issuers are often highly leveraged and may not
      have access to more traditional methods of financings and (viii) the
      possibility of adverse publicity and investor perceptions, whether or not
      due to fundamental analysis, which may result in widespread sales and
      declining market prices. If the Fund is required to seek recovery upon a
      default in the payment of principal or interest, it may incur additional
      expenses and may have limited legal recourse.
          As a result of the limited liquidity of high yield securities, their
      prices have at times experienced significant and rapid decline when a
      significant number of holders of high yield securities simultaneously
      decided to sell them. A decline is also likely in the high yield bond
      market during an economic downturn. An economic downturn or an increase in
      interest rates could severely disrupt the market for high yield securities
      and adversely affect the value of outstanding securities and the ability
      of the issuers to repay principal and interest. Yields on lower rated debt
      securities may rise dramatically in such periods, reflecting the risk that
      holders of such securities could lose a substantial portion of their value
      as a result of the issuers' financial restructuring or default. There can
      be no assurance that such declines will not recur. Because the market for
      high yield securities is less liquid, the valuation of these securities
      may require greater judgment than is necessary with respect to securities
      having more active markets.
          Although the prices of lower-rated bonds are generally less sensitive
      to interest rate changes than are higher-rated bonds, the prices of lower-

8

<PAGE>
      rated bonds may be more sensitive to adverse economic changes and
      developments regarding the individual issuer. Although the market for
      lower-rated debt securities is not new, and the market has previously
      weathered economic downturns, there has been in recent years a substantial
      increase in the use of such securities to fund corporate acquisitions and
      restructurings. Accordingly, the past performance of the market for such
      securities may not be an accurate indication of its performance during
      future economic downturns or periods of rising interest rates.
          If an investment grade security purchased by Investment Grade is
      subsequently given a rating below investment grade, the Adviser will
      consider that fact in determining whether to retain that security in the
      Fund's portfolio.
          The table below provides a summary of ratings assigned to debt
      holdings in the portfolios of Investment Grade and High Yield. These
      figures are dollar-weighted averages of month-end portfolio holdings
      during the fiscal year ended December 31, 1997, presented as a percentage
      of total investments. These percentages are historical and are not
      necessarily indicative of the quality of current or future portfolio
      holdings, which may vary.

          The dollar-weighted average of debt securities not rated by either
      Moody's or S&P amounted to 6% for Investment Grade and 8% High Yield. This
      may include securities rated by other NRSROs, as well as unrated
      securities. Unrated securities are not necessarily lower-quality
      securities, but may not be attractive to as many investors.
    
      U.S. Government Securities
   
          U.S. government securities include direct obligations of the U.S.
      Treasury and obligations issued by U.S. government agencies and
      instrumentalities, including securities that are supported by: (1) the
      full faith and credit of the United States (e.g., certificates of the
      Government National Mortgage Association ("GNMA")); (2) the right of the
      issuer to borrow from the U.S. Treasury (e.g., Federal Home Loan Banks
      securities); (3) the discretionary authority of the U.S. Treasury to lend
      to the issuer (e.g., Fannie Mae securities); and (4) solely by the
      creditworthiness of the issuer (e.g., Freddie Mac securities). Neither the
      U.S. Government nor any of its agencies or instrumentalities guarantees
      the market value of the securities they issue. Therefore, the market value
      of such securities can be expected to fluctuate in response to changes in
      interest rates.
    

      Inflation-Indexed Securities
          The Funds may also invest in U.S. Treasury securities whose principal
      value is adjusted daily in accordance with changes to the Consumer Price
      Index (also known as "Treasury Inflation-Protection Securities"). Interest
      is calculated on the basis of the adjusted principal value on the payment
      date. The principal value of inflation-indexed securities declines in
      periods of deflation, but holders at maturity receive no less than par. If
      inflation is lower than expected during the period a Fund holds the
      security, the Fund may earn less on it than on a conventional bond. Any
      increase in principal value is taxable in the year the increase occurs,
      even though holders do not receive cash representing the increase at that
      time. Changes in market interest rates from causes other than inflation
      will likely affect the market prices of inflation-indexed securities in
      the same manner as conventional bonds.

      Mortgage-Related Securities
          Mortgage-related securities represent interests in pools of mortgages.
      Mortgage-related securities may be issued by governmental or government-
      related entities or by non-governmental entities such as banks, savings
      and loan institutions, private mortgage insurance companies, mortgage
      bankers and other secondary market issuers.
          Mortgage-related securities differ from other forms of debt securities
      which normally provide for periodic payment of interest in fixed amounts
      with principal payments at maturity or specified call dates. In contrast,
      mortgage-related securities provide monthly payments which consist of
      interest and, in most cases, principal. In effect, these payments are a
      "pass-through" of the monthly payments made by the individual borrowers on
      their residential mortgage loans, net of any fees paid to the issuer or
      guarantor of such securities. Additional payments to holders of mortgage-
      related securities are caused by repayments resulting from the sale of the
      underlying residential property, refinancing or foreclosure. Some
      mortgage-related securities entitle the holders to receive

                                                                               9

<PAGE>
      all interest and principal payments owed on the mortgages in the pool, net
      of certain fees, regardless of whether or not the mortgagors actually make
      the payments.
          As prepayment rates of individual pools of mortgage loans vary widely,
      it is not possible to predict accurately the average life of a particular
      mortgage-related security. Although mortgage-related securities are issued
      with stated maturities of up to forty years, unscheduled or early payments
      of principal and interest on the underlying mortgages may shorten
      considerably the securities' effective maturities. When interest rates are
      declining, such prepayments usually increase. On the other hand, a
      decrease in the rate of prepayments, resulting from an increase in market
      interest rates, among other causes, may extend the effective maturities of
      mortgage-related securities, increasing their sensitivity to changes in
      market interest rates. The volume of prepayments of principal on a pool of
      mortgages underlying a particular mortgage-related security will influence
      the yield of that security. Increased prepayment of principal may limit a
      Fund's ability to realize the appreciation in the value of such securities
      that would otherwise accompany declining interest rates. An increase in
      mortgage prepayments could cause a Fund to incur a loss on a
      mortgage-related security that was purchased at a premium. In determining
      a Fund's average maturity, the Adviser must apply certain assumptions and
      projections about the maturity and prepayment of mortgage-related
      securities; actual prepayment rates may differ.
          A Fund may enter into mortgage "dollar roll" transactions with
      selected banks and broker-dealers pursuant to which that Fund sells
      mortgage-backed securities for delivery in the future (generally within 30
      days) and simultaneously contracts to repurchase substantially similar
      securities on a specified future date.
          RESTRICTIONS: Government Intermediate and Investment Grade normally
      may invest up to 50% of their total assets in mortgage-related securities,
      including those issued by the governmental or government-related entities
      referred to above. No more than 25% of Government Intermediate's or
      Investment Grade's total assets normally are invested in mortgage-related
      securities issued by non-governmental entities. Mortgage dollar roll
      transactions may be considered borrowings and, if so, will be subject to
      each Fund's investment limitation that, except for temporary purposes, a
      Fund will not borrow money in excess of 5% of its total assets at the time
      of borrowing.

      Government Mortgage-Related Securities
          GNMA pass-through securities are considered to have a very low risk of
      default in that (i) the underlying mortgage loan portfolio is comprised
      entirely of government-backed loans and (ii) the timely payment of both
      principal and interest on the securities is guaranteed by the full faith
      and credit of the U.S. Government. GNMA pass-through securities are,
      however, subject to the same market risk as comparable debt securities.
      Therefore, the effective maturity and market value of a Fund's GNMA
      securities can be expected to fluctuate in response to changes in interest
      rate levels.
   
          Freddie Mac, a corporate instrumentality of the U.S. Government,
      issues mortgage participation certificates ("PCs") which represent
      interests in mortgages from Freddie Mac's national portfolio. The mortgage
      loans in Freddie Mac's portfolio are not government backed; rather, the
      loans are either uninsured with loan-to-value ratios of 80% or less, or
      privately insured if the loan-to-value ratio exceeds 80%. Freddie Mac, not
      the U.S. Government, guarantees the timely payment of interest and
      ultimate collection of principal on Freddie Mac PCs.
    
   
          Fannie Mae is a government-sponsored corporation owned entirely by
      private stockholders that purchases residential mortgages from a list of
      approved seller/servicers, including savings and loan associations,
      savings banks, commercial banks, credit unions and mortgage bankers. Pass-
      through certificates issued by Fannie Mae ("Fannie Mae certificates") are
      guaranteed as to timely payment of principal and interest by Fannie Mae,
      not the U.S. Government.
    

      Privately Issued Mortgage-Related Securities
   
          Mortgage-related securities offered by private issuers include
      pass-through securities comprised of pools of conventional residential
      mortgage loans; mortgage-backed bonds which are considered to be
      obligations of the institution issuing the bonds and are collateralized by
      mortgage loans; and bonds and collateralized mortgage obligations ("CMOs")
      which are collateralized by mortgage-related securities issued by Freddie
      Mac, Fannie Mae, or GNMA or by pools of conventional mortgages.
    
          CMOs are typically structured with two or more classes or series which
      have different maturities and are generally retired in sequence. Each
      class of obligations is scheduled to receive periodic interest payments
      according to the coupon rate on the obligations. However, all monthly
      principal payments and any prepayments from the collateral

10

<PAGE>
      pool are paid first to the "Class 1" bondholders. The principal payments
      are such that the Class 1 obligations are scheduled to be completely
      repaid no later than, for example, five years after the offering date.
      Thereafter, all payments of principal are allocated to the next most
      senior class of bonds until that class of bonds has been fully repaid.
      Although full payoff of each class of bonds is contractually required by a
      certain date, any or all classes of obligations may be paid off sooner
      than expected because of an increase in the payoff speed of the pool.
          Mortgage-related securities created by non-governmental issuers
      generally offer a higher rate of interest than government and government-
      related securities because there are no direct or indirect government
      guarantees of payments in the former securities, resulting in higher
      risks. The market for conventional pools is smaller and less liquid than
      the market for the government and government-related mortgage pools.

      Asset-Backed Securities
          Asset-backed securities are securities that represent direct or
      indirect participations in, or are secured by and payable from, assets
      such as motor vehicle installment sales contracts, installment loan
      contracts, leases of various types of real and personal property and
      receivables from revolving credit (credit card) agreements. Such assets
      are securitized through the use of trusts and special purpose
      corporations. The value of such securities partly depends on loan
      repayments by individuals, which may be adversely affected during general
      downturns in the economy. Payments or distributions of principal and
      interest on asset-backed securities may be supported by credit
      enhancements, such as various forms of cash collateral accounts or letters
      of credit. Like mortgage-related securities, asset-backed securities are
      subject to the risk of prepayment. The risk that recovery on repossessed
      collateral might be unavailable or inadequate to support payments on
      asset-backed securities, however, is greater than is the case for
      mortgage-backed securities.

      Structured Securities (Investment Grade and High Yield only)
          Investment Grade and High Yield may invest in structured securities.
      These securities pay interest and/or repay principal in amounts determined
      by the performance of one or more financial indices or securities.
      Structured securities may be more volatile than the underlying index or
      security. The issuer of these securities is typically a bank or securities
      dealer. The value of the security may be affected by the issuer's
      creditworthiness. Like other debt instruments, they are also affected by
      changes in market interest rates.

      Convertible Securities
          A convertible security is a bond, debenture, note, preferred stock or
      other security that may be converted into or exchanged for a prescribed
      amount of common stock of the same or a different issuer within a
      particular period of time at a specified price or formula. A convertible
      security entitles the holder to receive interest paid or accrued on debt
      or the dividend paid on preferred stock until the convertible security
      matures or is redeemed, converted or exchanged. Before conversion,
      convertible securities have characteristics similar to non-convertible
      debt securities in that they ordinarily provide a stable stream of income
      with generally higher yields than those of common stocks of the same or
      similar issuers, but lower than the yield on non-convertible debt.
      Convertible securities are usually subordinated to comparable-tier
      non-convertible securities but rank senior to common stock in a
      corporation's capital structure.
          The value of a convertible security is a function of (1) its yield in
      comparison with the yields of other securities of comparable maturity and
      quality that do not have a conversion privilege and (2) its worth, at
      market value, if converted into the underlying common stock. Convertible
      securities are typically issued by smaller capitalized companies, whose
      stock prices may be volatile. The price of a convertible security often
      reflects such variations in the price of the underlying common stock in a
      way that non-convertible debt does not. A convertible security may be
      subject to redemption at the option of the issuer at a price established
      in the convertible security's governing instrument, which could have an
      adverse effect on a Fund's ability to achieve its investment objective.
          Government Intermediate and Investment Grade do not intend to exercise
      conversion rights for any convertible security they own and do not intend
      to hold any security which has been subject to conversion.

      Zero Coupon Bonds
          Zero coupon bonds are debt obligations which make no fixed interest
      payments but instead are issued at a significant discount from face value.
      Like other debt securities, the market price can reflect a premium or
      discount, in addition to the original issue discount, reflecting the
      market's judgment as to the issuer's creditworthiness, the interest rate
      or other similar factors. The original issue discount approximates the
      total amount of

                                                                              11

<PAGE>
      interest the bonds will accrue and compound over the period until maturity
      or the first interest payment date at a rate of interest reflecting the
      market rate of the security at the time of issuance. Because zero coupon
      bonds do not make periodic interest payments, their prices can be very
      volatile when market interest rates change.
          The original issue discount on zero coupon bonds must be included in a
      Fund's income ratably as it accrues. Accordingly, to continue to qualify
      for tax treatment as a regulated investment company and to avoid a certain
      excise tax, a Fund may be required to distribute as a dividend an amount
      that is greater than the total amount of cash it actually receives. See
      "Additional Tax Information" in the Statement of Additional Information.
      These distributions must be made from a Fund's cash assets or, if
      necessary, from the proceeds of sales of portfolio securities. Such sales
      could occur at a time which would be disadvantageous to that Fund and when
      that Fund would not otherwise choose to dispose of the assets.

      Stripped Mortgage-Backed Securities
          The Funds may also invest in stripped mortgage-backed securities,
      which are derivative securities usually structured with two classes that
      receive different proportions of the interest and principal distributions
      from an underlying pool of mortgage assets. The Funds may purchase
      securities representing only the interest payment portion of the
      underlying mortgage pools (commonly referred to as "IOs") or only the
      principal portion of the underlying mortgage pools (commonly referred to
      as "POs"). Stripped mortgage-backed securities are more sensitive to
      changes in prepayment and interest rates and the market for such
      securities is less liquid than is the case for traditional debt securities
      and mortgage-backed securities. The yield on IOs is extremely sensitive to
      the rate of principal payments (including prepayments) on the underlying
      mortgage assets, and a rapid rate of repayment may have a material adverse
      effect on such securities' yield to maturity. If the underlying mortgage
      assets experience greater than anticipated prepayments of principal, a
      Fund will fail to recoup fully its initial investment in these securities,
      even if they are rated high quality. Most IOs and POs are regarded as
      illiquid and will be included in each Fund's limit on illiquid securities.
      U.S. government-issued IOs and POs backed by fixed-rate mortgages may be
      deemed liquid by the Adviser, following guidelines and standards
      established by the Corporation's Board of Directors.

      Pay-In-Kind Bonds (HIGH YIELD ONLY)
          Pay-in-kind bonds pay "interest" through the issuance of additional
      bonds, thereby adding debt to the issuer's balance sheet. The market
      prices of these securities are likely to respond to changes in interest
      rates to a greater degree than the prices of securities paying interest
      currently. Pay-in-kind bonds carry additional risk in that, unlike bonds
      that pay interest throughout the period to maturity, the Fund will realize
      no cash until the cash payment date and the Fund may obtain no return at
      all on its investment if the issuer defaults.
   
          The holder of a pay-in-kind bond must accrue income with respect to
      the security prior to the receipt of cash payments thereon. To avoid
      liability for federal income and excise taxes, the Fund most likely will
      be required to distribute income accrued with respect to these securities,
      even though the Fund has not received that income in cash, and may be
      required to dispose of portfolio securities under disadvantageous
      circumstances in order to generate cash to satisfy these distribution
      requirements. See "Additional Tax Information" in the Statement of
      Additional Information.
    

      Preferred Stock
          Preferred stock may be purchased as a substitute for debt securities
      of the same issuer when, in the opinion of the Adviser, the preferred
      stock is more attractively priced in light of the risks involved.
      Preferred stock pays dividends at a specified rate and generally has
      preference over common stock in the payment of dividends and the
      liquidation of the issuer's assets but is junior to the debt securities of
      the issuer in those same respects. Unlike interest payments on debt
      securities, dividends on preferred stock are generally payable at the
      discretion of the issuer's board of directors, and shareholders may suffer
      a loss of value if dividends are not paid. Preferred shareholders
      generally have no legal recourse against the issuer if dividends are not
      paid. The market prices of preferred stocks are subject to changes in
      interest rates and are more sensitive to changes in the issuer's
      creditworthiness than are the prices of debt securities. Under ordinary
      circumstances, preferred stock does not carry voting rights.

      Trust Originated Preferred Securities
   
          The Funds may also invest in trust originated preferred securities, a
      type of security issued by financial institutions such as banks and
      insurance companies. Trust originated preferred securities represent
      interests in a trust formed by a financial institution. The trust sells
      preferred shares and
    

12

<PAGE>
      invests the proceeds in notes issued by the financial institution. These
      notes may be subordinated and unsecured. Distributions on the trust
      originated preferred securities match the interest payments on the notes;
      if no interest is paid on the notes, the trust will not make current
      payments on its preferred securities. Trust originated preferred
      securities currently enjoy favorable tax treatment. If the tax
      characterization of these securities were to change adversely, they could
      be redeemed by the issuers, which could result in a loss to a Fund. In
      addition, some trust originated preferred securities are restricted
      securities available only to qualified institutional buyers under Rule
      144A.

   
      Municipal Obligations
    
   
          The Funds may invest up to 5% of their respective net assets in
      municipal obligations. Municipal obligations include obligations issued to
      obtain funds for various public purposes, including constructing a wide
      range of public facilities, such as bridges, highways, housing, hospitals,
      mass transportation, schools and streets.
    

      Foreign Securities

GOVERNMENT INTERMEDIATE AND INVESTMENT GRADE:
          The Funds may invest in U.S. dollar-denominated debt securities issued
      by foreign companies and governments. The foreign government securities in
      which a Fund invests generally consist of obligations supported by
      national, state or provincial governments or similar political
      subdivisions. The Funds also may invest in debt securities of foreign
      "quasi-governmental agencies," which are issued by entities owned by a
      national, state or equivalent government or are obligations of a political
      unit that is not backed by the national government's full faith and credit
      and general taxing powers. Because the foreign securities in which the
      Funds invest are U.S. dollar-denominated, there is no risk of currency
      fluctuation, although there are other risks as set forth below.

HIGH YIELD:
          High Yield may invest up to 25% of its total assets in securities of
      domestic and foreign issuers that are denominated in currencies other than
      the U.S. dollar. To facilitate investment in foreign securities, the Fund
      may hold positions in foreign currencies. In addition, for hedging
      purposes, the Fund may purchase and write either listed or
      over-the-counter put and call options on foreign currencies or may enter
      into forward foreign currency contracts ("forward currency contracts").
          Forward currency contracts involve obligations to purchase or sell a
      specific amount of a specific currency at a future date, which may be any
      fixed number of days from the date of the contract agreed upon by the
      parties, at a price set at the time of the contract. By entering into a
      forward currency contract, the Fund "locks in" the exchange rate between
      the currency it will deliver and the currency it will receive for the
      duration of the contract. The Fund may enter into these contracts for the
      purpose of hedging against risk arising from its investment or anticipated
      investment in securities denominated in foreign currencies. Forward
      currency contracts involve certain risks, including the risk that currency
      movements will not be accurately predicted causing the Fund to sustain
      losses on these contracts.
          The Fund may invest in fixed-income and other debt securities of
      issuers based in emerging markets (including countries in Latin America,
      Eastern Europe, Asia and Africa).

      Risks of Foreign Securities
          Investment in foreign securities (including those denominated in U.S.
      dollars) presents certain risks, including those resulting from adverse
      political and economic developments, reduced availability of public
      information concerning issuers and the fact that foreign issuers generally
      are not subject to uniform accounting, auditing and financial reporting
      standards or to other regulatory practices and requirements comparable to
      those applicable to domestic issuers. Moreover, securities of many foreign
      issuers may be less liquid and their prices more volatile than those of
      comparable domestic issuers. Some foreign securities are subject to
      foreign income and withholding taxes. Additional risks associated with
      investing in foreign securities include the possibility of
      nationalization, expropriation or confiscatory taxation; adverse changes
      in investment or exchange control regulations (which may include
      suspension of the ability to transfer currency out of a country); and
      political instability. Changes in foreign exchange rates will affect the
      value of securities denominated or quoted in currencies other than the
      U.S. dollar irrespective of the performance of the underlying instrument.
      Some foreign governments have defaulted on principal and/or interest
      payments; in such cases, a Fund would have limited recourse to enforce its
      rights under the instruments it holds. The risks of foreign investment,
      described above, are greater for investments in emerging markets. Debt
      securities of issuers in such countries will typically be rated below
      investment grade or be of comparable quality.

                                                                              13

<PAGE>
      Repurchase Agreements
          Repurchase agreements are agreements under which U.S. government
      obligations or other high-quality, liquid debt securities are acquired
      from a securities dealer or bank subject to resale at an agreed-upon price
      and date. The securities are held for the Funds by a custodian bank, as
      collateral until resold and will be supplemented by additional collateral
      if necessary to maintain a total value equal to or in excess of the value
      of the repurchase agreement. A Fund bears a risk of loss in the event that
      the other party to a repurchase agreement defaults on its obligations and
      that Fund is delayed or prevented from exercising its right to dispose of
      the collateral securities, which may decline in value in the interim. A
      Fund will enter into repurchase agreements only with financial
      institutions which the Adviser believes present minimal risk of default
      during the term of the agreement based on guidelines established by the
      Corporation's Board of Directors.
          RESTRICTIONS: A Fund will not enter into repurchase agreements of more
      than seven days' duration if more than 10% (15% in the case of High Yield)
      of its net assets would be invested in such agreements and other illiquid
      investments.

      Forward Commitments
          Each Fund may enter into commitments to purchase U.S. government
      securities or other securities on a "forward commitment" basis, including
      purchases on a "when-issued" basis or a "to be announced" basis. When such
      transactions are negotiated, the price is fixed at the time the commitment
      is made, but delivery and payment for the securities takes place a later
      date. Such securities are often the most efficiently priced and have the
      best liquidity in the bond market. During the period between a commitment
      and settlement, no payment is made by the purchaser for the securities
      purchased and, thus, no interest accrues to the purchaser from the
      transaction. In a to be announced transaction, a Fund has committed to
      purchase securities for which all specific information is not yet known at
      the time of the trade, particularly the exact face amount in forward
      commitment mortgage-backed securities transactions.
          A Fund may sell the securities subject to a forward commitment
      purchase, which may result in a gain or loss. When a Fund purchases
      securities on a forward commitment basis, it assumes the risks of
      ownership, including the risk of price fluctuation, at the time of
      purchase, not at the time of receipt. Purchases of forward commitment
      securities also involve a risk of loss if the seller fails to deliver
      after the value of the securities has risen. Depending on market
      conditions, a Fund's forward commitment purchases could cause its net
      asset value to be more volatile. A Fund will direct State Street to place
      cash or U.S. government obligations in a separate account equal to the
      commitments of the Fund to purchase securities as a result of its forward
      commitment obligation.
          Each Fund may also enter into a forward commitment to sell only those
      securities it owns and will do so only with the intention of actually
      delivering the securities. The use of forward commitments enables a Fund
      to hedge against anticipated changes in interest rates and prices. In a
      forward sale, a Fund does not participate in gains or losses on the
      security occurring after the commitment date. A Fund will direct State
      Street to place the securities in a separate account. Forward commitments
      to sell securities also involve a risk of loss if the seller fails to take
      delivery after the value of the securities has declined. Further risks
      involving forward commitments are discussed in the section "Risks of
      Futures, Options and Forward Currency Contracts," below.
          Government Intermediate and Investment Grade each does not expect that
      purchases of forward commitments will at any time exceed, in the
      aggregate, 20% of its total assets.

      Futures and Options Transactions

GOVERNMENT INTERMEDIATE AND INVESTMENT GRADE:
          In an effort to protect against the effect of adverse changes in
      interest rates, a Fund may purchase and sell interest rate futures
      contracts and may purchase put options on interest rate futures contracts
      and debt securities (practices known as "hedging"). A futures contract is
      an agreement by a Fund to buy or sell securities at a specified date and
      price. The purchase of a put option on a futures contract allows a Fund,
      at its option, to enter into a particular futures contract to sell
      securities at any time up to the option's expiration date.
          A Fund may seek to enhance its income or hedge the portfolio by
      writing (selling) covered call options (i.e., a Fund will own the
      underlying instrument while the call is outstanding) and covered put
      options (i.e., a Fund will have cash or appropriate liquid securities in a
      segregated account in an amount not less than the exercise price while the
      put is outstanding).
          RESTRICTIONS: A Fund will not enter into any futures contracts or
      related options if the sum of the initial margin deposits on futures
      contracts and related options and premiums paid for related options the
      Fund has purchased would exceed 5%

14

<PAGE>
      of that Fund's total assets. A Fund will not purchase futures contracts or
      related options if, as a result, more than 33-1/3% of that Fund's total
      assets would be so invested.

HIGH YIELD:
          The Fund may write (sell) or purchase put and call options on domestic
      and foreign securities, securities indices and foreign currencies. Call
      options written by the Fund give the holder the right to buy the
      underlying securities or currencies from the Fund at a fixed exercise
      price up to a stated expiration date, or in the case of certain options,
      on such date. Put options give the holder the right to sell the underlying
      securities or currencies to the Fund at a fixed exercise price up to a
      stated expiration date, or in the case of certain options, on such date.
          The Fund may also enter into options on the yield "spread" or yield
      differential between two fixed-income securities, a transaction referred
      to as a "yield curve" option, for hedging and non-hedging purposes.
          The Fund may purchase and sell futures contracts on foreign
      currencies, securities, or indices of securities, including indices of
      fixed-income securities which may become available for trading. The Fund
      may also purchase and write options on such futures contracts.

      Risks of Futures, Options and Forward Currency Contracts
          Many options on debt securities are traded primarily on the
      over-the-counter ("OTC") market. OTC options differ from exchange-traded
      options in that the former are two-party contracts with price and other
      terms negotiated between buyer and seller and generally do not have as
      much market liquidity as exchange-traded options. Thus, when a Fund
      purchases an OTC option, it relies on the dealer from which it has
      purchased the option to make or take delivery of the securities underlying
      the option. Failure by the dealer to do so would result in the loss of the
      premium paid by a Fund as well as the loss of the expected benefit of the
      transaction. OTC options may be considered "illiquid securities" for
      purposes of the Funds' investment limitations.
          When a Fund purchases or sells a futures contract, the Fund is
      required to deposit with its custodian (or a broker, if legally permitted)
      a specified amount of cash or U.S. government securities ("initial
      margin"). Each day the Fund pays or receives cash ("variation margin")
      equal to the daily change in value of the futures contract. The use by a
      Fund of futures contracts or commodities option positions for other than
      bona fide hedging purposes is restricted by government regulations. (See
      the Statement of Additional Information.) If a Fund writes an option or
      sells a futures contract and is not able to close out that position prior
      to settlement date, the Fund may be required to deliver cash or securities
      substantially in excess of these amounts.
   
          The use of options, futures and forward currency contracts involves
      certain investment risks and transaction costs to which a Fund might not
      be subject if it did not use such instruments. These risks include (1)
      dependence on the Adviser's ability to predict movements in the prices of
      individual securities, fluctuations in the general securities markets or
      in market sectors and movements in interest rates and currency markets;
      (2) imperfect correlation between movements in the price of options,
      futures contracts or options thereon, or forward currency contracts and
      movements in the price of the securities or currencies hedged or used for
      cover; (3) the fact that skills and techniques needed to trade options,
      futures contracts and options thereon or to use forward currency contracts
      are different from those needed to select the securities in which the Fund
      invests; (4) lack of assurance that a liquid secondary market will exist
      for any particular option, futures contract or option thereon, or forward
      currency contract at any particular time which may result in unanticipated
      losses; (5) the possibility that the use of cover or segregation involving
      a large percentage of a Fund's assets could impede portfolio management or
      the Fund's ability to meet redemption requests or other short-term
      obligations; (6) the fact that, although use of these instruments for
      hedging purposes can reduce the risk of loss, they can also reduce the
      opportunity for gain, or even result in losses, by offsetting favorable
      price movements in hedged investments. The use of options for speculative
      purposes, i.e., to enhance income or to increase a Fund's exposure to a
      particular security or foreign currency, subjects the Fund to additional
      risk. The use of futures or forward currency contracts to hedge an
      anticipated purchase (other than a when-issued or delayed delivery
      purchase) also subjects a Fund to additional risk until the purchase is
      completed or the position is closed out.
    
          The Statement of Additional Information contains a more detailed
      description of futures, options and forward strategies.

      Restricted and Illiquid Securities
          Restricted securities are securities subject to legal or contractual
      restrictions on their resale, such as private placements. Such
      restrictions might

                                                                              15

<PAGE>
      prevent the sale of restricted securities at a time when sale would
      otherwise be desirable. Repurchase agreements maturing in more than seven
      days are considered illiquid. Illiquid securities, defined as securities
      that cannot be sold within 7 days at approximately the price they are
      valued, may be difficult to value, and a Fund may have difficulty
      disposing of such securities promptly.
          RESTRICTIONS: No more than 15% of High Yield's net assets will be
      invested in securities which are deemed illiquid. No more than 10% of
      Government Intermediate's or Investment Grade's net assets will be
      invested in illiquid securities.

      Lending
          Each Fund may loan its portfolio securities to qualified borrowers who
      deposit and maintain with the Fund cash collateral equal to at least 100%
      of the market value of the securities loaned.

      Interest Rate Swaps (HIGH YIELD ONLY)
          The Fund may enter into interest rate swaps. An interest rate swap is
      an agreement under which two parties exchange interest rate obligations,
      one of which typically is an interest rate fixed until the maturity of the
      obligation, while the other typically is a rate which changes with the
      changes in some other rate, such as the prime rate or the London Interbank
      Offered Rate (LIBOR). Such swaps will be used when the Fund wishes to
      effectively convert a floating rate asset into a fixed rate asset, or vice
      versa.

      Loan Participations and Assignments (HIGH YIELD ONLY)
          The Fund may also invest in "loan participations or assignments." In
      purchasing a loan participation or assignment, the Fund acquires some or
      all of the interest of a bank or other lending institution in a loan to a
      corporate borrower. Many such loans are secured and most impose
      restrictive covenants which must be met by the borrower and which are
      generally more stringent than the covenants available in publicly traded
      debt securities. However, interests in some loans may not be secured, and
      the Fund will be exposed to a risk of loss if the borrower defaults. Loan
      participations may also be purchased by the Fund when the borrowing
      company is already in default.
          In purchasing a loan participation, the Fund may have less protection
      under the federal securities laws than it has in purchasing traditional
      types of securities. The Fund's ability to assert its rights against the
      borrower will also depend on the particular terms of the loan agreement
      among the parties.
          RESTRICTIONS: Many of the interests in loans purchased by the Fund
      will be illiquid and therefore subject to the Fund's 15% limit on illiquid
      investments.

PORTFOLIO TURNOVER
   
          For the year ended December 31, 1997, Government Intermediate's
      portfolio turnover rate was 252%, Investment Grade's portfolio turnover
      rate was 259% and High Yield's portfolio turnover rate was 116%. Each Fund
      anticipates that its annual portfolio turnover rate may exceed 300%. The
      Funds may sell fixed-income securities and buy similar securities to
      obtain yield and take advantage of market anomalies, a practice which will
      increase the reported turnover rate of the Funds. A portfolio turnover
      rate in excess of 100% will involve correspondingly greater transaction
      costs which will be borne directly by a Fund. It may also increase the
      amount of net short-term capital gains, if any, realized by a Fund and
      thus may affect the tax treatment of distributions paid to shareholders
      because distributions of net short-term capital gains are taxable as
      ordinary income. Each Fund will take these possibilities into account as
      part of its investment strategy.
    

HOW TO PURCHASE AND REDEEM SHARES
          Institutional Clients of Fairfield may purchase Navigator Shares from
      Fairfield, the principal offices of which are located at 200 Gibraltar
      Road, Horsham, Pennsylvania 19044. Other investors eligible to purchase
      Navigator Shares may purchase them through a brokerage account with Legg
      Mason.
          Customers of certain Institutional Clients that maintain omnibus
      accounts with the Funds' transfer agent may obtain shares through those
      Institutions. Such Institutional Clients may receive payments from the
      Funds' distributor for account servicing, and may receive payments from
      their Customers for other services performed. Investors otherwise eligible
      to purchase Navigator Shares can purchase them from Legg Mason without
      receiving or paying for such other services.
          Institutional Clients purchasing or holding Navigator Shares on behalf
      of their Customers are responsible for the transmission of purchase and
      redemption orders (and the delivery of funds) to each Fund on a timely
      basis.

PURCHASE OF SHARES
          The minimum investment is $50,000 for the initial purchase of
      Navigator Shares of each Fund and $100 for each subsequent investment.
      Each Fund may change these minimum amounts at its

16

<PAGE>
      discretion. Institutional Clients may set different minimums for their
      Customers' investments in accounts invested in Navigator Shares.
          Share purchases will be processed at the net asset value next
      determined after Legg Mason or Fairfield has received your order; payment
      must be made within three business days to the selling organization.
      Orders received by Legg Mason or Fairfield before the close of regular
      trading on the New York Stock Exchange ("Exchange") (normally 4:00 p.m.
      Eastern time) ("close of the Exchange") on any day the Exchange is open
      will be executed at the net asset value determined as of the close of the
      Exchange on that day. Orders received by Legg Mason or Fairfield after the
      close of the Exchange or on days the Exchange is closed will be executed
      at the net asset value determined as of the close of the Exchange on the
      next day the Exchange is open. See "How Net Asset Value is Determined" on
      page 19.
          Each Fund reserves the right to reject any order for its shares, to
      suspend the offering of shares for a period of time, or to waive any
      minimum investment requirements. In addition to Institutional Clients
      purchasing shares directly from Fairfield, Navigator Shares may be
      purchased through procedures established by Fairfield in connection with
      requirements of Customer Accounts of various Institutional Clients.
          No sales charge is imposed by any of the Funds in connection with the
      purchase of Navigator Shares. Depending upon the terms of a particular
      Customer Account, however, Institutional Clients may charge their
      Customers fees for automatic investment and other cash management services
      provided in connection with investments in a Fund. Information concerning
      these services and any applicable charges will be provided by the
      Institutional Clients. This Prospectus should be read by Customers in
      connection with any such information received from the Institutional
      Clients. Any such fees, charges or other requirements imposed by an
      Institutional Client upon its Customers will be in addition to the fees
      and requirements described in this Prospectus.

REDEMPTION OF SHARES
          Shares may ordinarily be redeemed by a shareholder via telephone, in
      accordance with the procedures described below. However, Customers of
      Institutional Clients wishing to redeem shares held in Customer Accounts
      at the Institution may redeem only in accordance with instructions and
      limitations pertaining to their Account at the Institution.
          Fairfield clients can make telephone redemption requests by calling
      Fairfield at 1-800-441-3885. Legg Mason clients should call their
      financial advisors at 1-800-822-5544. Callers should have available the
      number of shares (or dollar amount) to be redeemed and their account
      number.
          Orders for redemption received by Legg Mason or Fairfield before the
      close of the Exchange on any day when the Exchange is open will be
      transmitted to Boston Financial Data Services ("BFDS"), transfer agent for
      the Funds, for redemption at the net asset value per share determined as
      of the close of the Exchange on that day. Requests for redemption received
      by Legg Mason or Fairfield after the close of the Exchange will be
      executed at the net asset value determined as of the close of the Exchange
      on its next trading day. A redemption request received by Legg Mason or
      Fairfield may be treated as a request for repurchase and, if it is
      accepted by Legg Mason, your shares will be purchased at the net asset
      value per share determined as of the next close of the Exchange.
          Shareholders may have their telephone redemption requests paid by a
      direct wire to a domestic commercial bank account previously designated by
      the shareholder, or mailed to the name and address in which the
      shareholder's account is registered with the respective Fund. Such
      payments will normally be transmitted on the next business day following
      receipt of a valid request for redemption.
          The proceeds of redemption or repurchase may be more or less than the
      original cost. If the shares to be redeemed or repurchased were paid for
      by check (including certified or cashier's checks) within 10 business days
      of the redemption or repurchase request, the proceeds may not be disbursed
      unless that Fund can be reasonably assured that the check has been
      collected.
          To the extent permitted by law, each Fund reserves the right to take
      up to seven days to make payment upon redemption if, in the judgment of
      the Adviser, the respective Fund could be adversely affected by immediate
      payment. (The Statement of Additional Information describes several other
      circumstances in which the date of payment may be postponed or the right
      of redemption suspended.)
          The Funds will not be responsible for the authenticity of redemption
      instructions received by telephone, provided they follow reasonable
      procedures to identify the caller. The Funds may request identifying
      information from callers or employ identification numbers. A Fund may be

                                                                              17

<PAGE>
      liable for losses due to unauthorized or fraudulent instructions if it
      does not follow reasonable procedures. Telephone redemption privileges are
      available automatically to all shareholders unless certificates have been
      issued. Shareholders who do not wish to have telephone redemption
      privileges should call their financial advisor for further instructions.
          Because of the relatively high cost of maintaining small accounts,
      each Fund may elect to close any account with a current value of less than
      $500 by redeeming all of the shares in the account and mailing the
      proceeds to the investor. However, the Funds will not redeem accounts that
      fall below $500 solely as a result of a reduction in net asset value per
      share. If a Fund elects to redeem the shares in an account, the
      shareholder will be notified that the account is below $500 and will be
      allowed 60 days in which to make an additional investment in order to
      avoid having the account closed.

HOW SHAREHOLDER ACCOUNTS ARE MAINTAINED
   
          A shareholder account is established automatically for each
      shareholder. Any shares the shareholder purchases or receives as a
      dividend or other distribution will be credited directly to the account at
      the time of purchase or receipt. Fund shares may not be held in, or
      transferred to, an account with any brokerage firm other than Fairfield,
      Legg Mason or their affiliates. The Funds do not issue share certificates.
    
          Navigator Shares sold to Institutional Clients acting in a fiduciary,
      advisory, custodial, or other similar capacity on behalf of persons
      maintaining Customer Accounts at Institutional Clients will normally be
      held of record by the Institutional Clients. Therefore, in the context of
      Institutional Clients, references in this Prospectus to shareholders mean
      the Institutional Clients rather than their Customers.

HOW NET ASSET VALUE IS DETERMINED
          Net asset value per Navigator Share of each Fund is determined daily
      as of the close of the Exchange, on every day that the Exchange is open,
      by subtracting the liabilities attributable to Navigator Shares from the
      total assets attributable to such shares and dividing the result by the
      number of Navigator Shares outstanding. Securities owned by each Fund for
      which market quotations are readily available are valued at current market
      value. In the absence of readily available market quotations, securities
      are valued at fair value as determined by the Corporation's Board of
      Directors. With respect to High Yield, where a security is traded on more
      than one market, which may include foreign markets, the securities are
      generally valued on the market considered by the Adviser to be the primary
      market. Securities with remaining maturities of 60 days or less are valued
      at amortized cost. The Fund will value its foreign securities in U.S.
      dollars on the basis of the then-prevailing exchange rates.

DIVIDENDS AND OTHER DISTRIBUTIONS
   
          Each Fund declares dividends to holders of Navigator Shares out of its
      investment company taxable income attributable to those shares, which
      consists of net investment income, any net short-term capital gain and, in
      the case of High Yield, any net gains from certain foreign currency
      transactions. Dividends from net investment income are declared daily and
      paid monthly for Government Intermediate and Investment Grade and are
      declared and paid monthly for High Yield. Shareholders begin to earn
      dividends on their Fund shares as of settlement date, which is normally
      the third business day after their orders are placed with their financial
      advisor. Dividends from net short-term capital gain and distributions of
      substantially all net capital gain (the excess of net long-term capital
      gain over net short-term capital loss) and, in the case of High Yield, net
      realized gains from foreign currency transactions generally are declared
      and paid after the end of the taxable year in which the gain is realized.
      A second distribution of net capital gain may be necessary in some years
      to avoid imposition of the excise tax described under the heading
      "Additional Tax Information" in the Statement of Additional Information.
      Shareholders may elect to:
    

          1. Receive both dividends and other distributions in Navigator Shares
      of the distributing Fund;
          2. Receive dividends in cash and other distributions in Navigator
      Shares of the distributing Fund;
          3. Receive dividends in Navigator Shares of the distributing Fund and
      other distributions in cash; or
          4. Receive both dividends and other distributions in cash.

          If a shareholder has elected to receive dividends and/or other
      distributions in cash and the postal or other delivery service is unable
      to deliver checks to the shareholder's address of record, such
      shareholder's distribution option will automatically be converted to
      having all dividends and other

18

<PAGE>
   
      distributions reinvested in additional shares. No interest will accrue on
      amounts represented by uncashed distribution or redemption checks. In
      certain cases, shareholders may reinvest dividends and other distributions
      in the corresponding class of shares of another Navigator fund. Please
      contact a financial advisor for additional information about this option.
      Qualified retirement plans that obtained Navigator Shares through exchange
      generally receive dividends and other distributions in additional shares
      of the distributing Fund.
    
          If no election is made, both dividends and other distributions are
      credited to the Institutional Client's account in Navigator Shares of the
      distributing Fund at the net asset value of the shares determined as of
      the close of the Exchange on the reinvestment date. Shares received
      pursuant to any of the first three (reinvestment) elections above also are
      credited to the account at that net asset value. If an investor elects to
      receive dividends and/or other distributions in cash, a check will be
      sent. Investors purchasing through Fairfield may elect at any time to
      change the distribution option by notifying the applicable Fund in writing
      at: [insert complete Fund name], c/o Fairfield Group, Inc., 200 Gibraltar
      Road, Horsham, Pennsylvania 19044. Those purchasing through Legg Mason
      should write to: [insert complete Fund name], c/o Legg Mason Funds
      Processing, P.O. Box 1476, Baltimore, Maryland, 21203-1476. An election
      must be received at least 10 days before the record date in order to be
      effective for dividends and other distributions paid to shareholders as of
      that date.

TAX TREATMENT OF DIVIDENDS AND OTHER DISTRIBUTIONS
   
          Each Fund intends to continue to qualify for treatment as a regulated
      investment company under the Internal Revenue Code of 1986, as amended so
      that it will be relieved of federal income tax on that part of its
      investment company taxable income and net capital gain that is distributed
      to its shareholders.
    
   
          Dividends from a Fund's investment company taxable income (whether
      paid in cash or reinvested in Navigator Shares) are taxable to its
      shareholders (other than qualified retirement plans and other tax-exempt
      investors) as ordinary income to the extent of that Fund's earnings and
      profits. Distributions of a Fund's net capital gain (whether paid in cash
      or reinvested in Navigator Shares), when designated as such, are taxable
      to those shareholders as long-term capital gain, regardless of how long
      they have held their Fund shares. Under the Taxpayer Relief Act of 1997
      ("Tax Act"), different maximum tax rates apply to a noncorporate
      taxpayer's net capital gain depending on the holding period of the
      security and the taxpayer's marginal rate of federal income tax. The
      relevant holding period is determined by how long the Fund has held the
      portfolio security on which the gain was earned, not by how long you have
      held your Fund shares.
    
   
          The Funds send each shareholder a notice following the end of each
      calendar year specifying, among other things, the amounts of all dividends
      and other distributions paid (or deemed paid) during that year. The
      notice will tell you what portion of the capital gain falls into each of
      the different tax rate categories mentioned above.
    
   
          Each Fund is required to withhold 31% of all dividends, capital gain
      distributions and redemption proceeds payable to any individuals and
      certain other noncorporate shareholders who do not provide the Fund with a
      certified taxpayer identification number. Each Fund also is required to
      withhold 31% of all dividends and capital gain distributions payable to
      such shareholders who otherwise are subject to backup withholding.
    
   
          A redemption of Navigator Shares may result in taxable gain or loss to
      the redeeming shareholder, depending on whether the redemption proceeds
      are more or less than the shareholder's adjusted basis for the redeemed
      shares. An exchange of Navigator Shares of any Fund for shares of another
      Navigator fund will generally have similar tax consequences. See
      "Shareholder Services -- Exchange Privilege." If Fund shares are purchased
      within 30 days before or after redeeming at a loss other shares of the
      same Fund (regardless of class), all or part of that loss will not be
      deductible and instead will increase the basis of the newly purchased
      shares.
    
          A dividend or other distribution paid shortly after shares have been
      purchased, although in effect a return of investment, is subject to
      federal income tax. Accordingly, an investor should recognize that a
      purchase of Navigator Shares immediately prior to the record date for a
      dividend or other distribution could cause the investor to incur tax
      liabilities and should not be made solely for the purpose of receiving the
      dividend or other distribution.
   
          The foregoing is only a summary of some of the important federal
      income tax considerations generally affecting each Fund and its
      shareholders; see the Statement of Additional Information for a
    

                                                                              19

<PAGE>
      further discussion. In addition to federal income tax, you may also be
      subject to state and local income taxes on distributions from the Funds,
      depending on the laws of your home state and locality, though the portion
      of the dividends paid by each Fund attributable to direct U.S. government
      obligations is not subject to state and local income taxes in most
      jurisdictions. Each Fund's annual notice to shareholders regarding the
      amount of dividends identifies this portion. Prospective shareholders are
      urged to consult their tax advisers with respect to the effects of this
      investment on their own tax situations.

SHAREHOLDER SERVICES

CONFIRMATIONS AND REPORTS
          Every shareholder of record will receive a confirmation of each new
      share transaction with a Fund, which will also show the total number of
      shares being held in safekeeping by the Fund's transfer agent for the
      account of the shareholder.
          Confirmations for each purchase and redemption transaction (except a
      reinvestment of dividends or other distributions) of Navigator Shares made
      by Institutional Clients acting in a fiduciary, advisory, custodial, or
      other similar capacity on behalf of persons maintaining Customer Accounts
      at Institutional Clients will be sent to the Institutional Client by the
      transfer agent. Beneficial ownership of shares by Customer Accounts will
      be recorded by the Institutional Client and reflected in the regular
      account statements provided by them to their Customers.
          Reports will be sent to each Fund's shareholders at least semiannually
      showing its portfolio and other information; the annual report for each
      Fund will contain financial statements audited by the Corporation's
      independent accountants.
          Shareholder inquiries should be addressed to: "[insert complete Fund
      name], c/o Legg Mason Funds Processing, P.O. Box 1476, Baltimore, Maryland
      21203-1476" or "c/o Fairfield Group Inc., 200 Gibraltar Road, Horsham,
      Pennsylvania 19044."

EXCHANGE PRIVILEGE
   
          Holders of Navigator Shares are entitled to exchange them for
      Navigator Shares of any of the Legg Mason Funds, the Legg Mason Cash
      Reserve Trust, the Navigator Money Market Fund, Inc. and the Navigator
      Tax-Free Money Market Fund, Inc., provided that such shares are eligible
      for sale under applicable state securities laws.
    
          Investments by exchange into the other Navigator funds are made at the
      per share net asset value determined on the same business day as
      redemption of the Fund shares you wish to exchange. To obtain further
      information concerning the exchange privilege and prospectuses of other
      Navigator funds, or to make an exchange, please contact your financial
      advisor. To effect an exchange by telephone, please call your financial
      advisor with the information described in the section "How to Purchase and
      Redeem Shares," page 17. The other factors relating to telephone
      redemptions described in that section apply also to telephone exchanges.
      Please read the prospectus for the other fund(s) carefully before you
      invest by exchange.
   
           Each Fund reserves the right to modify or terminate the exchange
      privilege upon 60 days' notice to shareholders. Some Institutional Clients
      may not offer all of the Navigator Funds for exchange.
    
THE CORPORATION'S BOARD OF DIRECTORS, MANAGER AND INVESTMENT ADVISER

BOARD OF DIRECTORS
   
          The business and affairs of each Fund are managed under the direction
      of the Corporation's Board of Directors.
    

   
MANAGEMENT AGREEMENTS
    
   
          Each Fund has a management agreement with LMFA which was approved by
      the Corporation's Board of Directors (each a "Management Agreement").
      Under the Management Agreements, LMFA is obligated to provide the Funds
      with investment management and administrative services, and to oversee the
      Funds' relationships with outside service providers, such as the
      custodian, transfer agent, accountants, and lawyers.
    
   
          For services under the Management Agreements, LMFA receives a fee from
      each Fund, calculated daily and payable monthly, at the following annual
      rates of its average daily net assets:
    

   
<TABLE>
<S><C>
      Government Intermediate                          0.55%
      Investment Grade                                 0.60%
      High Yield                                       0.65%
</TABLE>
    

   
          Because of fee waivers (see below) Government Intermediate paid a
      management fee of .34%, and Investment Grade paid a management fee of .21%
      during the fiscal year ended December 31, 1997.
    

   
ADVISORY AGREEMENTS
    
   
          LMFA has entered into an investment advisory agreement with Western
      Asset Management Company ("Western Asset") to provide investment advisory
      services to each Fund.
    
   
          Western Asset has the responsibility for making investment decisions
      and placing orders to buy
    

20

<PAGE>
   
      or sell a particular security for each Fund in accordance with its
      investment objective, policies and limitations. Under each Advisory
      Agreement, Western Asset receives an advisory fee from LMFA (not the
      Funds) computed daily and payable monthly, at annual rates of each Fund's
      average daily net assets as follows:
    

   
<TABLE>
<S><C>
      Government Intermediate     0.20%, not to exceed the fee
                                  paid to LMFA
      Investment Grade            0.24%, or 40% of the fee
                                  received by LMFA
      High Yield                  0.50%, or 77% of the fee
                                  received by LMFA
</TABLE>
    

   
FEE WAIVERS
    
   
          LMFA has agreed to waive its fees in any month to the extent a Fund's
      expenses related to Navigator Shares (exclusive of taxes, interest,
      brokerage and extraordinary expenses) exceed during that month annual
      rates of that Fund's average daily net assets attributable to Navigator
      Shares as follows:
    

   
<TABLE>
<S><C>
      Government Intermediate      0.50% until May 1, 1999 or
                                   when the Fund reaches net
                                   assets of $400 million
      Investment Grade             0.50% until May 1, 1999 or
                                   when the Fund reaches net
                                   assets of $150 million
</TABLE>
    

   
      These agreements are voluntary and may or may not be renewed by LMFA.
      Waiver by LMFA reduces a Fund's expenses and increases its yield and total
      return.
    

   
EXPENSE RATIOS
    
   
          For the year ended December 31, 1997, the ratio of each Fund's
      expenses to its average net assets (after application of any fee waivers)
      was:
    

   
<TABLE>
<S><C>
      Government Intermediate                          0.45%
      Investment Grade                                 0.43%
      High Yield                                       0.80%
</TABLE>
    

   
LMFA
    
   
          LMFA acts as investment adviser or manager to seventeen investment
      company portfolios which had aggregate assets under management of over
      $11.2 billion as of March 31, 1998. LMFA's address is 100 Light Street,
      Baltimore, Maryland 21202.
    
   
          Like other mutual funds, financial and business organizations around
      the world, the Funds could be adversely affected if the computer systems
      used by LMFA and other service providers do not properly process and
      calculate date-related information and data from and after January 1,
      2000. This is commonly known as the "Year 2000 Problem." LMFA is taking
      steps that it believes are reasonably designed to address the Year 2000
      Problem with respect to the computer system that it uses and to obtain
      assurances that comparable steps are being taken by the Funds' other,
      major service providers. At this time, however, there can be no assurance
      that these steps will be sufficient to avoid any adverse impact on the
      Funds.
    

   
WESTERN ASSET
    
   
          Western Asset renders investment advice to fifteen open-end investment
      companies and one closed-end investment company, which together had
      aggregate assets under management of approximately $5.2 billion as of
      March 31, 1998. Western Asset also renders investment advice to private
      accounts with fixed income assets under management of approximately $33.7
      billion as of that date. The address of Western Asset is 177 East Colorado
      Boulevard, Pasadena, California 91105.
    
   
          Western Asset has managed fixed income portfolios continuously since
      its founding in 1971, and has focused exclusively on such accounts since
      1984. In managing fixed-income portfolios, Western Asset first studies the
      range of factors that influence interest rates and develops a long-term
      interest rate forecast. It then allocates available funds to those sectors
      of the market (for example, government, corporate, or mortgage-backed
      securities), which it considers most attractive. Then it selects the
      specific issues which it believes represent the best values. All three
      decisions are integral parts of the Adviser's portfolio management process
      and contribute to its performance record.
    

   
PORTFOLIO MANAGEMENT
    
   
          An investment committee has been responsible for the day-to-day
      management of each Fund since its inception.

DESCRIPTION OF THE CORPORATION AND ITS SHARES
          The Corporation is a diversified open-end investment company which was
      incorporated in Maryland on April 28, 1987. The Articles of Incorporation
      of the Corporation permit the Board of Directors to create additional
      series (or portfolios), each of which may issue separate classes of
      shares. There are currently four portfolios of the Corporation. While
      additional series may be created in the future, there is no intention at
      this time to form any particular additional series.
          The Corporation has authorized one billion shares of common stock, par
      value $.001 per share. Government Intermediate, Investment Grade and High
      Yield currently offer two classes of shares -- Class Y (known as
      "Navigator Shares") and Class A (known as "Primary Shares"). The two
      classes represent interests in the same pool of assets. A separate vote is
      taken by a class of shares of a Fund if a matter affects just that class
      of shares. Each class of shares may bear certain differing class-specific
      expenses. Salespersons and others entitled to receive compensation for
      selling or servicing Fund shares may receive more with respect to one
      class than another.
   
          Investors may obtain more information concerning the Primary Class
      from their financial advisor or by calling 1-800-822-5544.
    
          The Board of Directors of the Corporation does not anticipate that
      there will be any conflicts among the interests of the holders of the
      different classes of Fund shares. On an ongoing basis, the Board will
      consider whether any such conflict exists and, if so, take appropriate
      action.
          Shareholders of the Funds are entitled to one vote per share and
      fractional votes for fractional shares held. Voting rights are not
      cumulative. All shares of the Funds are fully paid and nonassessable and
      have no preemptive or conversion rights.
   
          Shareholders' meetings will not be held except where the 1940 Act
      requires a shareholder vote on certain matters (including the election of
      directors, approval of an advisory contract, and approval of a plan of
      distribution pursuant to Rule 12b-1). The Corporation will call a special
      meeting of the shareholders at the request of 10% or more of the shares
      entitled to vote; shareholders wishing to call such a meeting should
      submit a written request to their respective Fund at 100 Light Street,
      Baltimore, Maryland 21202, stating the purpose of the proposed meeting and
      the matters to be acted upon. The address of BFDS is P.O. Box 953, Boston,
      MA 02103.
    
          Each Fund acknowledges that it is solely responsible for the
      information or any lack of information about it in this joint Prospectus
      and in the joint Statement of Additional Information, and no other Fund is
      responsible therefor. There is a possibility that one Fund might be deemed
      liable for misstatements or omissions regarding another Fund in this
      Prospectus or in the joint Statement of Additional Information; however,
      the Funds deem this possibility slight.

APPENDIX

RATINGS OF SECURITIES

DESCRIPTION OF MOODY'S INVESTORS SERVICE, INC. ("MOODY'S") CORPORATE BOND
RATINGS:
          Aaa -- Bonds which are rated Aaa are judged to be of the best quality.
      They carry the smallest degree of investment risk and are generally
      referred to as "gilt edge". Interest payments are protected by a large or
      exceptionally stable margin and principal is secure. While the various
      protective elements are likely to change, such changes as can be
      visualized are most unlikely to impair the fundamentally strong position
      of such issues.
          Aa -- Bonds which are rated Aa are judged to be of high quality by all
      standards. Together with the Aaa group they comprise what are generally
      known as high-grade bonds. They are rated lower than the best bonds
      because margins of protection may not be as large as in Aaa securities or
      fluctuation of protective elements may be of greater amplitude or there
      may be other elements present which make the long-term risks appear
      somewhat larger than the Aaa securities.
          A -- Bonds which are rated A possess many favorable investment
      attributes and are to be considered upper-medium-grade obligations.
      Factors giving security to principal and interest are considered adequate,
      but elements may be present which suggest a susceptibility to impairment
      some time in the future.
          Baa -- Bonds which are rated Baa are considered medium-grade
      obligations, (i.e., they are neither highly protected nor poorly secured).
      Interest payments and principal security appear adequate for the present
      but certain protective elements may be lacking or may be
      characteristically unreliable over any great length of time. Such bonds
      lack outstanding investment characteristics and in fact have speculative
      characteristics as well.
          Ba -- Bonds which are rated Ba are judged to have speculative
      elements; their future cannot be considered well-assured. Often the
      protection of interest and principal payments may be very moderate, and
      thereby not well safeguarded during both good and bad times over the
      future. Uncertainty of position characterizes bonds in this class.
          B -- Bonds which are rated B generally lack characteristics of the
      desirable investment. Assurance of interest and principal payments or
      maintenance of other terms of the contract over any long period of time
      may be small.
          Caa -- Bonds which are rated Caa are of poor standing and may be in
      default or there may be present elements of danger with respect to
      principal or interest.
          Ca -- Bonds which are rated Ca represent obligations which are
      speculative in a high degree and are often in default or have other marked
      shortcomings.
          C -- Bonds which are rated C are the lowest rated class of bonds and
      can be regarded as having extremely poor prospects of ever attaining any
      real investment standing.

DESCRIPTION OF STANDARD & POOR'S ("S&P") CORPORATE BOND RATINGS:
          AAA -- This is the highest rating assigned by S&P to an obligation.
      Capacity to pay interest and repay principal is extremely strong.
          AA -- Bonds rated AA have a very strong capacity to pay interest and
      repay principal and differ from the higher rated issues only in small
      degree.
          A -- Bonds rated A have a strong capacity to pay interest and repay
      principal, although they are somewhat more susceptible to the adverse
      effects of changes in circumstances and economic conditions than debt in
      higher categories.
          BBB -- Bonds rated BBB are regarded as having an adequate capacity to
      pay principal and interest. Whereas they normally exhibit adequate
      protection parameters, adverse economic conditions or changing
      circumstances are more likely to lead to a weakened capacity to pay
      interest and repay principal for bonds in this category than for bonds in
      higher rated categories.
          BB, B, CCC, CC -- Bonds rated BB, B, CCC and CC are regarded, on
      balance, as predominately speculative with respect to the issuer's
      capacity to pay interest and repay principal in accordance with the terms
      of the obligation. BB indicates the lowest degree of speculation and CC
      the highest degree of speculation. While such bonds will likely have some
      quality and protective characteristics, these are outweighed by large
      uncertainties or major risk exposures to adverse conditions.
          C -- Bonds on which no interest is being paid are rated C.
          D -- Bonds rated D are in payment default and payment of interest
      and/or repayment of principal is in arrears.

DESCRIPTION OF MOODY'S PREFERRED STOCK RATINGS:
          aaa -- An issue which is rated "aaa" is considered to be a top-quality
      preferred stock. This rating indicates good asset protection and the least
      risk of dividend impairment within the universe of preferred stocks.

                                      A-1

<PAGE>
          aa -- An issue which is rated "aa" is considered a high-grade
      preferred stock. This rating indicates that there is a reasonable
      assurance that earnings and asset protection will remain relatively
      well-maintained in the foreseeable future.
          a -- An issue which is rated "a" is considered to be an
      upper-medium-grade preferred stock. While risks are judged to be somewhat
      greater than in the "aaa" and "aa" classification, earnings and asset
      protection are, nevertheless, expected to be maintained at adequate
      levels.
          baa -- An issue which is rated "baa" is considered to be a
      medium-grade preferred stock, neither highly protected nor poorly secured.
      Earnings and asset protection appear adequate at present but may be
      questionable over any great length of time.
          ba -- An issue which is rated "ba" is considered to have speculative
      elements and its future cannot be considered well assured. Earnings and
      asset protection may be very moderate and not
      well safeguarded during adverse periods. Uncertainty of position
      characterizes preferred stocks in this class.
          b -- An issue which is rated "b" generally lacks the characteristics
      of a desirable investment. Assurance of dividend payments and maintenance
      of other terms of the issue over any long period of time may be small.
          caa -- An issue which is rated "caa" is likely to be in arrears on
      dividend payments. This rating designation does not purport to indicate
      the future status of payments.
          ca -- An issue which is rated "ca" is speculative in a high degree and
      is likely to be in arrears on dividends with little likelihood of eventual
      payments.
          c -- This is the lowest rated class of preferred stock or preference
      stock. Issues so rated can be regarded as having extremely poor prospects
      of ever attaining any real investment standing.

                           INVESTMENT GRADE PORTFOLIO
                              HIGH YIELD PORTFOLIO
                     (PRIMARY SHARES AND NAVIGATOR SHARES)
                                      AND
                     U.S. GOVERNMENT MONEY MARKET PORTFOLIO

                      STATEMENT OF ADDITIONAL INFORMATION

         MUTUAL FUND SHARES ARE NOT DEPOSITS OR OBLIGATIONS OF, OR GUARANTEED OR
ENDORSED BY, ANY BANK OR OTHER DEPOSITORY INSTITUTION. SHARES ARE NOT INSURED BY
THE FDIC, THE FEDERAL RESERVE BOARD OR ANY OTHER AGENCY, AND ARE SUBJECT TO
INVESTMENT RISK, INCLUDING THE POSSIBLE LOSS OF THE PRINCIPAL AMOUNT INVESTED.

   
         This Statement of Additional Information is not a prospectus and should
be read in conjunction with the Prospectus for Primary Shares or for Navigator
Shares, both dated May 1, 1998, which have been filed with the Securities and
Exchange Commission ("SEC"). Copies of the Prospectuses are available without
charge from the distributor, Legg Mason Wood Walker, Incorporated ("Legg Mason")
(address and telephone numbers listed below).
    

         Legg Mason U.S. Government Intermediate-Term Portfolio ("Government
Intermediate"), Legg Mason Investment Grade Income Portfolio ("Investment
Grade"), Legg Mason High Yield Portfolio ("High Yield") and Legg Mason U.S.
Government Money Market Portfolio ("Government Money Market") (each separately
referred to as a "Fund" and collectively referred to as the "Funds") are
separate series of Legg Mason Income Trust, Inc. ("Corporation"), an open-end
diversified management investment company.

         Government Intermediate seeks to provide investors with high current
income consistent with prudent investment risk and liquidity needs. In
attempting to achieve this objective, the Funds' investment adviser, Western
Asset Management Company ("Adviser"), under normal circumstances, invests at
least 75% of Government Intermediate's assets in obligations issued or
guaranteed by the U.S. Government, its agencies or instrumentalities. Government
Intermediate expects to maintain an average dollar-weighted maturity of between
three and ten years. The Fund seeks to provide income higher than that of money
market funds and greater price stability than funds with longer average
maturities.

         Investment Grade seeks to provide investors with a high level of
current income through investment in a diversified portfolio of debt securities.
In attempting to achieve Investment Grade's objective, the Adviser, under normal
circumstances, invests primarily in debt securities which it considers to be
investment grade. Investment Grade expects to maintain an average
dollar-weighted maturity of between five and twenty years. The Fund's current
yield is expected to be higher than the current yields of mutual funds that own
debt securities with shorter average maturities.

         High Yield seeks to provide investors with a high level of current
income. As a secondary objective, the Fund seeks capital appreciation. In
attempting to achieve High Yield's objectives, the Adviser, under normal
circumstances, invests not less than 65% of its total assets in high-yield,
fixed-income securities (including those commonly known as "junk bonds"); that
is, income-producing debt securities and preferred stocks of all types,
including (but not limited to) corporate debt securities and preferred stock,
convertible securities, zero coupon securities, deferred interest securities,
mortgage-backed securities and asset-backed securities. In addition to other
risks, these bonds are subject to greater fluctuations in value and risk of loss
of income and principal due to default by the issuer than are lower-yielding,
higher-rated bonds. Therefore, an investment in this Fund may not be suitable
for all investors.

         Government Money Market seeks to obtain high current income consistent
with liquidity and conservation of principal. In attempting to achieve this
objective, the Adviser invests only in debt obligations issued or guaranteed by
the U.S. Government, its agencies or instrumentalities, in repurchase agreements
collateralized by such instruments, and in securities issued or guaranteed by
multi-national development

banks of which the U.S. is a member.  The Fund attempts to maintain a stable net
asset value of $1.00 per share, although there can be no assurance that it will
always be able to do so.

and Navigator High Yield ("Navigator Shares"), described in this Statement of
Additional Information, represent interests in Government Intermediate,
Investment Grade and High Yield that are currently offered for sale only to
institutional clients of the Fairfield Group, Inc. ("Fairfield") for investment
of their own funds and funds for which they act in a fiduciary capacity, to

exercises discretionary investment management responsibility (such institutional
investors are referred to collectively as "Institutional Clients" and accounts
of the customers with such Clients ("Customers") are referred to collectively as

basis and having net assets of at least $200 million, to clients of Bartlett &
Co. ("Bartlett") who, as of December 19, 1996, were shareholders of Bartlett
Short Term Bond Fund or Bartlett Fixed Income Fund and for whom Bartlett acts as
ERISA fiduciary, and to any qualified retirement plan of Legg Mason, Inc. or of
any of its affiliates. The Navigator Class of Shares may not be purchased by
individuals directly, but Institutional Clients may purchase shares for Customer
Accounts maintained for individuals.
    

         The Primary Class of shares of Government Intermediate, Investment
Grade, High Yield and Government Money Market ("Primary Shares") is offered for
sale to all other investors and may be purchased directly by individuals.

         Navigator Shares and Primary Shares are sold and redeemed without any

Clients may charge their Customer Accounts for services provided in connection
with the purchase or redemption of shares. Each Fund will pay management fees to

         11. Purchase any security if, as a result thereof, 25% or more of its
total assets would be invested in the securities of issuers having their
principal business activities in the same industry. This limitation does not
apply to securities issued or guaranteed by the U.S. government, its agencies or
instrumentalities and repurchase agreements with respect thereto.

         As noted above, the fundamental investment limitations of each Fund,
along with its investment objective, may not be changed without the vote of a
majority of the Fund's outstanding voting securities. Under the 1940 Act, a
"vote of a majority of the outstanding voting securities" of a Fund means the
affirmative vote of the lesser of (1) more than 50% of the outstanding shares of
the Fund or (2) 67% or more of the shares present at a shareholders' meeting if
more than 50% of the outstanding shares are represented at the meeting in person
or by proxy. If a percentage restriction described above is complied with at the
time an investment is made, a later increase in percentage resulting from
changing values of portfolio securities or in the amount of assets of the Fund
will not be considered a violation of any of those restrictions. Except as
otherwise noted, the investment policies and limitations described in this
Statement of Additional Information are non-fundamental and may be changed
without a shareholder vote.

         The following are some of the non-fundamental limitations which High
Yield currently observes. High Yield may not:

   
    

   
         1. Buy securities on "margin," except for short-term credits necessary
for clearance of portfolio transactions and except that the Fund may make margin
deposits in connection with the use of permitted currency futures contracts and
options on currency futures contracts;

         2. Make short sales of securities or maintain a short position, except
that the Fund may (a) make short sales and maintain short positions in
connection with its use of options, futures contracts and options on
    

                                       5

<PAGE>



futures contracts and (b) sell short "against the box" (the Fund does not intend
to make short sales against the box in excess of 5% of its net assets during the
coming year);

   
    

   
         3. Hold more than 10% of the outstanding voting securities of any one
issuer.
    


         YIELD FACTORS AND RATINGS Standard & Poor's ("S&P"), Moody's Investors
Service, Inc. ("Moody's") and other nationally recognized statistical rating
organizations ("NRSROs") are private services that provide ratings of the credit
quality of obligations. Investment grade bonds are generally considered to be
those bonds rated at the time of purchase within one of the four highest grades
assigned by S&P or Moody's. A Fund may use these ratings in determining whether
to purchase, sell or hold a security. These ratings represent Moody's and S&P's
opinions as to the quality of the obligations which they undertake to rate. It
should be emphasized, however, that ratings are general and are not absolute
standards of quality. Consequently, obligations with the same maturity, interest
rate and rating may have different market prices.

         Credit rating agencies attempt to evaluate the safety of principal and
interest payments and do not evaluate the risks of fluctuations in market value.
Also, rating agencies may fail to make timely changes in credit ratings in
response to subsequent events, so than an issuer's current financial condition
may be better or worse than the rating indicates. Subsequent to its purchase by
a Fund, an issue of obligations may cease to be rated or its rating may be
reduced below the minimum rating required for purchase by that Fund. The Adviser
will consider such an event in determining whether a Fund (other than Government
Money Market) should continue to hold the obligation, but is not required to
dispose of it. Government Money Market will consider disposing of the obligation
in accordance with Rule 2a-7 under the 1940 Act.

         In addition to ratings assigned to individual bond issues, the Adviser
will analyze interest rate trends and developments that may affect individual
issuers, including factors such as liquidity, profitability and asset quality.
The yields on bonds and other debt securities in which a Fund invests are
dependent on a variety of factors, including general money market conditions,
general conditions in the bond market, the financial condition of the issuer,
the size of the offering, the maturity of the obligation and its rating. There
may be a wide variation in the quality of bonds, both within a particular
classification and between classifications. A bond issuer's obligations are
subject to the provisions of bankruptcy, insolvency and other laws affecting the
rights and remedies of bond holders or other creditors of an issuer; litigation
or other conditions may also adversely affect the power or ability of bond
issuers to meet their obligations for the payment of interest and principal.

         INTEREST RATE FUTURES CONTRACTS Interest rate futures contracts, which
are traded on commodity futures exchanges, provide for the sale by one party and
the purchase by another party of a specified type and amount of financial
instruments (or an index of financial instruments) at a specified future date.
Interest rate futures contracts currently exist covering such financial
instruments as U.S. Treasury bonds, notes and bills, Government National
Mortgage Association ("GNMA") certificates, bank certificates of deposit and 90-
day commercial paper. An interest rate futures contract may be held until the
underlying instrument is delivered and paid for on the delivery date, but most
contracts are closed out before then by taking an offsetting position on a
futures exchange.

         A Fund may purchase an interest rate futures contract (that is, enter
into a futures contract to purchase an underlying financial instrument) when it
intends to purchase fixed-income securities but has not yet done so. This
strategy is sometimes called an anticipatory hedge. This strategy is intended to
minimize the effects of an increase in the price of the securities the Fund
intends to purchase (but may also reduce the effects of a decrease in price),
because the value of the futures contract would be expected to rise and fall in
the same direction as the price of the securities the Fund intends to purchase.
The Fund could purchase the intended securities either by holding the contract
until delivery and receiving the financial instrument underlying the futures
contract, or by purchasing the securities directly and closing out the futures
contract position. If the Fund no longer wishes to purchase the securities, the
Fund would close out the futures contract before delivery.

         A Fund may sell a futures contract (that is, enter into a futures
contract to sell an underlying financial instrument) to offset price changes of
securities it already owns. This strategy is intended to minimize any price
changes in the securities the Fund owns (whether increases or decreases) caused
by interest rate changes, because the value of the futures contract would be
expected to move in the opposite direction from the value of the securities
owned by the Fund. Each Fund does not expect ordinarily to hold futures
contracts it has sold until delivery or to use securities it owns to satisfy
delivery requirements. Instead, each Fund expects to close out such contracts
before the delivery date.

         The prices of interest rate futures contracts depend primarily on the
value of the instruments on which they are based, the price changes of which, in
turn, primarily reflect changes in current interest rates. Because there are a
limited number of types of interest rate futures contracts, it is likely that
the standardized futures contracts available to each Fund will not exactly match
the securities that Fund wishes to hedge or intends to purchase, and
consequently will not provide a perfect hedge against all price fluctuation.
Because fixed-income instruments all respond similarly to changes in interest
rates, however, a futures contract the underlying instrument of which differs
from the securities that Fund wishes to hedge or intends to purchase may still
provide protection against changes in interest rate levels. To compensate for
differences in historical volatility between positions a Fund wishes to hedge
and the standardized futures contracts available to it, a Fund may purchase or
sell futures contracts with a greater or lesser value than the securities it
wishes to hedge or intends to purchase. A Fund may not use these instruments for
speculation or leverage.

         FUTURES TRADING If a Fund does not wish to hold a futures contract
position until the underlying instrument is delivered and paid for on the
delivery date, it may attempt to close out the contract by entering into an
offsetting position on a futures exchange that provides a secondary market for
the contract. A futures contract is closed out by entering into an opposite
position in an identical futures contract (for example, by purchasing a contract
on the same instrument and with the same delivery date as a contract the Fund
had sold) at the current price as determined on the futures exchange. A Fund's
gain or loss on closing out a futures contract depends on the difference between
the price at which the Fund entered into the contract and the price at which the
contract is closed out. Transaction costs in opening and closing futures
contracts must also be taken into account. There can be no assurance that a Fund
will be able to offset a futures position at the time it wishes to, or at a
price that is advantageous. If a Fund were unable to enter into an offsetting
position in a futures contract, it might have to continue to hold the contract
until the delivery date, in which

                                       7

<PAGE>



case it would continue to bear the risk of price fluctuation in the contract
until the underlying instrument was delivered and paid for.

         At the time a Fund enters into an interest rate futures contract, it is
required to deposit with its custodian, in the name of the futures broker (known
as a futures commission merchant, or "FCM"), a percentage of the contract's
value. This amount, which is known as initial margin, generally equals 5% or
less of the value of the futures contract. Initial margin is in the nature of a
good faith deposit or performance bond, and is returned to the Fund when the
futures position is terminated, after all contractual obligations have been
satisfied. Futures margin does not represent a borrowing by a Fund, unlike
margin extended by a securities broker, and depositing initial margin in
connection with futures positions does not constitute purchasing securities on
margin for the purposes of each Fund's investment limitations. Initial margin
may be maintained either in cash or in liquid, high-quality debt securities such
as U.S. government securities.

         As the contract's value fluctuates, payments known as variation margin
or maintenance margin are made to or received from the FCM. If the contract's
value moves against a Fund (i.e., the Fund's futures position declines in
value), the Fund may be required to make payments to the FCM, and, conversely,
the Fund may be entitled to receive payments from the FCM if the value of its
futures position increases. This process is known as "marking to market" and
takes place on a daily basis.

         In addition to initial margin deposits, the Fund will instruct its
custodian to segregate additional cash and appropriate liquid securities to
cover its obligations under futures contracts it has purchased and to ensure
that the contracts are unleveraged. The value of the assets held in the
segregated account will be equal to the daily market value of all outstanding
futures contracts purchased by the Fund, less the amount deposited as initial
margin. Where a Fund enters into positions that substantially offset one
another, it may segregate assets equal to only one side of the transaction,
consistent with SEC staff interpretive positions. When a Fund has sold futures
contracts to hedge securities it owns, it will not sell those securities (or
lend them to another party) while the contracts are outstanding, unless it
substitutes other similar securities for the securities sold or lent. Each Fund
will not sell futures contracts with a value exceeding the value of securities
it owns, except that a Fund may do so to the extent necessary to adjust for
differences in historical volatility between the securities owned and the
contracts used as a hedge.

         RISKS OF INTEREST RATE FUTURES CONTRACTS By purchasing an interest rate
futures contract, a Fund in effect becomes exposed to price fluctuations
resulting from changes in interest rates, and by selling a futures contract a
Fund neutralizes those fluctuations. If interest rates fall, a Fund would expect
to profit from an increase in the value of the instrument underlying a futures
contract it has purchased, and if interest rates rise, a Fund would expect to
offset the resulting decline in the value of the securities it owns by profits
in a futures contract it has sold. If interest rates move in the direction
opposite that which was contemplated at the time of purchase, however, a Fund's
positions in futures contracts could have a negative effect on that Fund's net
asset value. If interest rates rise when a Fund has purchased futures contracts,
that Fund could suffer a loss in its futures positions. Similarly, if interest
rates fall, losses in a futures contract that Fund has sold could negate gains
on securities the Fund owns, or could result in a net loss to the Fund. In this
sense, successful use of interest rate futures contracts by a Fund will depend
on the Adviser's ability to hedge the Fund in an advantageous way at the
appropriate time.

         Other than the risk that interest rates will not move as expected, the
primary risk in employing interest rate futures contracts is that the market
value of the futures contracts may not move in concert with the value of the
securities a Fund wishes to hedge or intends to purchase. This may result from
differences between the instrument underlying the futures contracts and the
securities a Fund wishes to hedge or intends to purchase, as would be the case,
for example, if a Fund hedged U.S. Treasury bonds by selling futures contracts
on U.S. Treasury notes.


                                       8

<PAGE>



         Even if the securities which are the objects of a hedge are identical
to those underlying the futures contract, there may not be perfect price
correlation between the two. Although the value of interest rate futures
contracts is primarily determined by the price of the underlying financial
instruments, the value of interest rate futures contracts is also affected by
other factors, such as current and anticipated short-term and long-term interest
rates, the time remaining until expiration of the futures contract, and
conditions in the futures markets, which may not affect the current market price
of the underlying financial instruments in the same way. In addition, futures
exchanges establish daily price limits for interest rate futures contracts, and
may halt trading in the contracts if their prices move up or down more than a
specified daily limit on a given day. This could distort the relationship
between the price of the underlying instrument and the futures contract, and
could prevent prompt liquidation of unfavorable futures positions. The value of
a futures contract may also move differently from the price of the underlying
financial instrument because of inherent differences between the futures and
securities markets, including variations in speculative demand for futures
contracts and for debt securities, the differing margin requirements for futures
contracts and debt securities, and possible differences in liquidity between the
two markets.

         PUT OPTIONS ON INTEREST RATE FUTURES CONTRACTS Purchasing a put option
on an interest rate futures contract gives a Fund the right to assume a seller's
position in the contract at a specified exercise price at any time up to the
option's expiration date. In return for this right, the Fund pays the current
market price for the option (known as the option premium), as determined on the
commodity futures exchange where the option is traded.

         Each Fund may purchase put options on interest rate futures contracts
to hedge against a decline in the market value of securities that Fund owns and
not for speculation or leverage. Because a put option is based on a contract to
sell a financial instrument at a certain price, its value will tend to move in
the opposite direction from the price of the financial instrument underlying the
futures contract; that is, the put option's value will tend to rise when prices
fall, and fall when prices rise. By purchasing a put option on an interest rate
futures contract, a Fund would attempt to offset potential depreciation of
securities it owns by appreciation of the put option. This strategy is similar
to selling the underlying futures contract directly.

         A Fund's position in a put option on an interest rate futures contract
may be terminated either by exercising the option (and assuming a seller's
position in the underlying futures contract at the option's exercise price) or
by closing out the option at the current price as determined on the futures
exchange. If the put option is not exercised or closed out before its expiration
date, the entire premium paid will be lost by that Fund. The Fund could profit
from exercising a put option if the current market value of the underlying
futures contract were less than the sum of the exercise price of the put option
and the premium paid for the option (because the Fund would, in effect, be
selling the futures contract at a price higher than the current market price).
The Fund could also profit from closing out a put option if the current market
price of the option is greater than the premium the Fund paid for the option.
Transaction costs must also be taken into account in these calculations. The
Fund may close out an option it has purchased by selling an identical option
(that is, an option on the same futures contract, with the same exercise price
and expiration date) in a closing transaction on a futures exchange that
provides a secondary market for the option. A Fund is not required to make
futures margin payments when it purchases an option on an interest rate futures
contract.

         Compared to the sale of an interest rate futures contract, the purchase
of a put option on an interest rate futures contract involves a smaller
potential risk to a Fund, because the maximum amount at risk is the premium paid
for the option (plus related transaction costs). If prices of debt securities
remain stable, however, purchasing a put option may involve a greater
probability of loss than selling a futures contract, even though the amount of
the potential loss is limited. The Adviser will consider the different risk and
reward characteristics of options and futures contracts when selecting hedging
instruments.

         RISKS OF TRANSACTIONS IN OPTIONS ON INTEREST RATE FUTURES CONTRACTS
Options on interest rate futures contracts are subject to risks similar to those
described above with respect to interest rate futures contracts. These risks
include the risk that the Adviser may not hedge a Fund in an advantageous way at
the appropriate time, the risk of imperfect price correlation between the option
and the securities being hedged, and the risk that there may not be an active
secondary market for the option.

         Although the Adviser will purchase only those options for which there
appears to be a liquid secondary market, there can be no assurance that such a
market will exist for any particular option at any particular time. If there
were no liquid secondary market for a particular option, a Fund might have to
exercise an option it had purchased in order to realize any profit.

         OPTIONS WRITING ON DEBT SECURITIES Each Fund may from time to time
write (sell) covered call options and covered put options on certain of its
portfolio securities. A Fund may write call options on securities in its
portfolio in an attempt to realize, through the premium that Fund receives, a
greater current return than would be realized on the securities alone. A Fund
may write put options in an attempt to realize enhanced income when it is
willing to purchase the underlying instrument for its portfolio at the exercise
price. A Fund may also purchase call options for the purpose of acquiring the
underlying instruments for its portfolio. At times, the net cost of acquiring
instruments in this manner (the exercise price of the call option plus the
premium paid) may be less than the cost of acquiring the instruments directly.

         When it writes a covered call option, a Fund obligates itself to sell
the underlying security to the purchaser of the option at a fixed price if the
purchaser exercises the option during the option period. A call is "covered" if
the Fund owns the underlying securities or, in the case of options on certain
U.S. government securities, the Fund maintains with its custodian in a
segregated account cash or appropriate liquid securities with a value sufficient
to meet its obligations under the call. When a Fund writes a call option, it
receives a premium from the purchaser. During the option period, the Fund
forgoes the opportunity to profit from any increase in the market price of the
security above the exercise price of the option, but retains the risk that the
price of the security may decline.

         Each Fund may also write covered put options. When a Fund writes a put
option, it receives a premium and gives the purchaser of the put the right to
sell the underlying security to the Fund at the exercise price at any time
during the option period. A put is "covered" if the Fund maintains cash or
appropriate liquid securities with a value equal to the exercise price in a
segregated account. The risk in writing puts is that the market price of the
underlying security may decline below the exercise price (less the premium
received).

         Each Fund may seek to terminate its obligations as a writer of a put or
call option prior to its expiration by entering into a "closing purchase
transaction." A closing purchase transaction is the purchase of an option
covering the same underlying security and having the same exercise price and
expiration date as an option previously written by the Fund on which it wishes
to terminate its obligation.

         Although not a fundamental policy subject to shareholder vote, each
Fund presently does not intend to write options on portfolio securities
exceeding 25% of its total assets. Normally, covered call options will be
written on those portfolio securities which the Adviser does not expect to have
significant short-term capital appreciation.

         RISKS OF WRITING OPTIONS ON DEBT SECURITIES When a Fund writes an
option, it assumes the risk of fluctuations in the value of the underlying
security in return for a fixed premium, it must be prepared to satisfy exercise
of the option at any time until the expiration date. The writing of options
could also result in an increase in the Fund's turnover rate, particularly in
periods of appreciation in the market price of the underlying securities. In
addition, writing options on portfolio securities involves a number of other
risks, including the risk that the Adviser may not correctly predict interest
rate movement and the risk that there may

                                       10

<PAGE>



not be a liquid secondary market for the option, as a result of which the Fund
might be unable to effect a closing transaction.

         If a Fund is unable to close out an option it has written, it must
continue to bear the risks associated with the option, and must continue to hold
cash or securities to cover the option until the option is exercised or expires.
Each Fund may engage in options on securities which are not traded on national
exchanges ("unlisted options"). Because unlisted options may be closed out only
with the other party to the option transaction, it may be more difficult to
close out unlisted options than listed options.

   
         CERTAIN LIMITATIONS ON FUTURES AND OPTIONS STRATEGIES The Corporation
has filed on behalf of each Fund a notice of eligibility for exclusion from the
definition of the term "commodity pool operator" with the Commodity Futures
Trading Commission ("CFTC") and the National Futures Association, which regulate
trading in the futures markets. Under Section 4.5 of the regulations under the
Commodity Exchange Act, the notice of eligibility must include representations
that each Fund will use futures contracts and related options solely for bona
fide hedging purposes within the meaning of the CFTC regulations, provided that
each Fund may hold futures contracts and related options that do not fall within
the definition of bona fide hedging transactions if, with respect to such
non-hedging transactions, the sum of initial margin deposits on futures
contracts and related options and premiums paid for related options, after
taking into account unrealized profits and losses on such contracts, does not
exceed 5% of that Fund's net assets; and provided further that each Fund may
exclude the amount by which an option is "in the money" in computing such 5%.
Each Fund will not purchase futures contracts or related options if as a result
more than 33 1/3% of that Fund's total assets would be so invested. Where a Fund
enters into two positions that substantially offset each other, it determines
compliance with the foregoing limitation by considering its net exposure to
changes in the underlying instrument or market. There is a risk, however, that
the two positions may not be entirely correlated, and therefore may not offset
one another to the extent expected. In that case, the expsosure could
unexpectedly exceed 33 1/3 of total assets. These limits on a Fund's investments
in futures contracts are not fundamental and may be changed by the Board of
Directors as regulatory agencies permit. Each Fund will not modify these limits
to increase its permissible futures and related options activities without
supplying additional information in a supplement to a current Prospectus or
Statement of Additional Information that has been distributed or made available
to each Fund's shareholders.
    

The following information about futures and options applies to High Yield:

         The Fund may purchase call options on securities that the Adviser
intends to include in the Fund's investment portfolio in order to fix the cost
of a future purchase. Purchased options also may be used as a means of
participating in an anticipated price increase of a security on a more limited
risk basis than would be possible if the security itself were purchased. In the
event of a decline in the price of the underlying security, use of this strategy
would serve to limit the Fund's potential loss to the option premium paid;
conversely, if the market price of the underlying security increases above the
exercise price and the Fund either sells or exercises the option, any profit
realized will be reduced by the premium.

         The Fund may purchase put options in order to hedge against a decline
in the market value of securities held in its portfolio or to enhance income.
The put option enables the Fund to sell the underlying security at the
predetermined exercise price; thus the potential for loss to the Fund below the
exercise price is limited to the option premium paid. If the market price of the
underlying security is higher than the exercise price of the put option, any
profit the Fund realizes on the sale of the security would be reduced by the
premium paid for the put option less any amount for which the put option may be
sold.

         The Fund may write covered call options on securities in which it is
authorized to invest. Because it can be expected that a call option will be
exercised if the market value of the underlying security increases to a level
greater than the exercise price, the Fund might write covered call options on
securities generally

                                       11

<PAGE>



when its Adviser believes that the premium received by the Fund will exceed the
extent to which the market price of the underlying security will exceed the
exercise price. The strategy may be used to provide limited protection against a
decrease in the market price of the security, in an amount equal to the premium
received for writing the call option less any transaction costs. Thus, in the
event that the market price of the underlying security held by the Fund
declines, the amount of such decline will be offset wholly or in part by the
amount of the premium received by the Fund. If, however, there is an increase in
the market price of the underlying security and the option is exercised, the
Fund would be obligated to sell the security at less than its market value. The
Fund would give up the ability to sell the portfolio securities used to cover
the call option while the call option was outstanding. Such securities would
also be considered illiquid in the case of over-the-counter ("OTC") options
written by the Fund, and therefore subject to the Fund's limitation on investing
no more than 15% of its net assets in illiquid securities. In addition, the Fund
could lose the ability to participate in an increase in the value of such
securities above the exercise price of the call option because such an increase
would likely be offset by an increase in the cost of closing out the call option
(or could be negated if the buyer chose to exercise the call option at an
exercise price below the securities' current market value).

         The sale of a put option on a security by the Fund also serves to
partially offset fluctuations in the cost of a security that the Fund
anticipates purchasing. If the price of the security rises, the increased cost
to the Fund of purchasing the security will be offset, in whole or in part, by
the premium received. In the event, however, that the price of the security
falls below the exercise price of the option and the option is exercised, the
Fund will be required to purchase the security from the holder of the option at
a price in excess of the current market price of the security. The Fund's loss
on this transaction will be offset, in whole or in part, to the extent of the
premium received by the Fund for writing the option.

         The Fund may purchase put and call options and write put and covered
call options on bond indices in much the same manner as securities options,
except that bond index options may serve as a hedge against overall fluctuations
in the debt securities markets (or a market sector) rather than anticipated
increases or decreases in the value of a particular security. A bond index
assigns a value to the securities included in the index and fluctuates with
changes in such values. Settlements of bond index options are effected with cash
payments and do not involve the delivery of securities. Thus, upon settlement of
a bond index option, the purchaser will realize, and the writer will pay, an
amount based on the difference between the exercise price and the closing price
of the bond index. The effectiveness of hedging techniques using bond index
options will depend on the extent to which price movements in the bond index
selected correlate with price movements of the securities in which the Fund
invests.

         The Fund may purchase and write covered straddles on securities,
currencies or bond indices. A long straddle is a combination of a call and a put
option purchased on the same security, index or currency where the exercise
price of the put is less than or equal to the exercise price of the call. The
Fund would enter into a long straddle when the Adviser believes that it is
likely that interest rates or currency exchange rates will be more volatile
during the term of the options than the option pricing implies. A short straddle
is a combination of a call and a put written on the same security, index or
currency where the exercise price of the put is less than or equal to the
exercise price of the call. In a covered short straddle, the same issue of
security or currency is considered cover for both the put and the call that the
Fund has written. The Fund would enter into a short straddle when the Adviser
believes that it is unlikely that interest rates or currency exchange rates will
be as volatile during the term of the options as the option pricing implies. In
such case, the Fund will set aside cash or appropriate liquid securities in a
segregated account with its custodian equivalent in value to the amount, if any,
by which the put is in-the-money, that is, the amount by which the exercise
price of the put exceeds the current market value of the underlying security.
Straddles involving currencies are subject to the same risks as other foreign
currency options.

Foreign Currency Options and Related Risks
- ------------------------------------------

                                       12

<PAGE>



         The Fund may purchase and write (sell) options on foreign currencies in
order to hedge against the risk of foreign exchange rate fluctuation on foreign
securities the Fund holds or which it intends to purchase. For example, if the
Fund enters into a contract to purchase securities denominated in a foreign
currency, it could effectively fix the maximum U.S. dollar cost of the
securities by purchasing call options on that foreign currency. Similarly, if
the Fund held securities denominated in a foreign currency and anticipated a
decline in the value of that currency against the U.S. dollar, it could hedge
against such a decline by purchasing a put option on the currency involved. In
the event of exchange rate movements adverse to the Fund's options position, it
may forfeit the entire amount of the premium plus related transaction costs. In
addition, the Fund may purchase call options on foreign currency to enhance
income when its Adviser anticipates that the currency will appreciate in value,
but the securities denominated in that currency do not present attractive
investment opportunities.

         If the Fund writes an option on foreign currency, it will constitute
only a partial hedge, up to the amount of the premium received, and the Fund
could be required to purchase or sell foreign currencies at disadvantageous
exchange rates, thereby incurring losses. The Fund may use options on currency
to cross- hedge, which involves writing or purchasing options on one currency to
hedge against changes in exchange rates of a different, but related, currency.
If the Fund uses cross-hedging, it may experience losses on both the currency in
which it has invested and the currency used for hedging, if the two currencies
do not vary with the expected degree of correlation.

         The Fund's ability to establish and close out positions in such options
is subject to the maintenance of a liquid secondary market. Although many
options on foreign currencies are exchange traded, the majority are traded on
the OTC market. The Fund will not purchase or write such options unless, in the
opinion of the Adviser, the market for them has developed sufficiently. There
can be no assurance that a liquid secondary market will exist for a particular
option at any specific time. In addition, options on foreign currencies are
affected by all of those factors that influence foreign exchange rates and
foreign investments generally. These OTC options also involve credit risks that
may not be present in the case of exchange-traded currency options.

Futures Contracts and Options on Futures Contracts
- --------------------------------------------------

         The Fund will limit its use of futures contracts and options on futures
contracts to hedging transactions or other circumstances permitted by regulatory
authorities. For example, the Fund might use futures contracts to attempt to
hedge against anticipated changes in interest rates that might adversely affect
either the value of the Fund's securities or the price of the securities that
the Fund intends to purchase. The Fund's hedging may include sales of futures
contracts as an offset against the effect of expected increases in interest
rates, and purchases of futures contracts as an offset against the effect of
expected declines in interest rates. Although other techniques could be used to
reduce exposure to interest rate fluctuations, the Fund may be able to hedge its
exposure more effectively and perhaps at a lower cost by using futures contracts
and options on futures contracts.

         The Fund also may use futures contracts on fixed income instruments and
options thereon to hedge its investment portfolio against changes in the general
level of interest rates. A futures contract on a fixed income instrument is a
bilateral agreement pursuant to which one party agrees to make, and the other
party agrees to accept, delivery of the specified type of fixed income security
called for in the contract at a specified future time and at a specified price.
The Fund may purchase a futures contract on a fixed income security when it
intends to purchase fixed income securities but has not yet done so. This
strategy may minimize the effect of all or part of an increase in the market
price of the fixed income security that the Fund intends to purchase in the
future. A rise in the price of the fixed income security prior to its purchase
may be either offset by an increase in the value of the futures contract
purchased by the Fund or avoided by taking delivery of the fixed income
securities under the futures contract. Conversely, a fall in the market price of
the underlying fixed

                                       13

<PAGE>



income security may result in a corresponding decrease in the value of the
futures position. The Fund may sell a futures contract on a fixed income
security in order to continue to receive the income from a fixed income
security, while endeavoring to avoid part or all of the decline in the market
value of that security that would accompany an increase in interest rates.

         The Fund may purchase a call option on a futures contract to hedge
against a market advance in debt securities that the Fund plans to acquire at a
future date. The purchase of a call option on a futures contract is analogous to
the purchase of a call option on an individual fixed income security that can be
used as a temporary substitute for a position in the security itself. The Fund
also may write covered call options on futures contracts as a partial hedge
against a decline in the price of fixed income securities held in the Fund's
investment portfolio, or purchase put options on futures contracts in order to
hedge against a decline in the value of fixed income securities held in the
Fund's investment portfolio. The Fund may write a put option on a security that
the Fund anticipates purchasing to partially offset the cost of purchasing that
security; however, the cost will only be offset to the extent of the premium the
Fund receives for writing the option.

         The Fund may sell securities index futures contracts in anticipation of
a general market or market sector decline that could adversely affect the market
value of its investments. To the extent that a portion of the Fund's investments
correlate with a given index, the sale of futures contracts on that index could
reduce the risks associated with a market decline and thus provide an
alternative to the liquidation of securities positions. For example, if the Fund
correctly anticipates a general market decline and sells securities index
futures to hedge against this risk, the gain in the futures position should
offset some or all of the decline in the value of the portfolio. The Fund may
purchase securities index futures contracts if a significant market or market
sector advance is anticipated. Such a purchase of a futures contract would serve
as a temporary substitute for the purchase of individual securities, which
securities may then be purchased in an orderly fashion. This strategy may
minimize the effect of all or part of an increase in the market price of
securities that the Fund intends to purchase. A rise in the price of the
securities should be partly or wholly offset by gains in the futures position.

         As in the case of a purchase of a securities index futures contract,
the Fund may purchase a call option on a securities index futures contract to
hedge against a market advance in securities that the Fund plans to acquire at a
future date. The Fund may write put options on securities index futures as a
partial anticipatory hedge and may write covered call options on securities
index futures as a partial hedge against a decline in the prices of securities
held in its portfolio. This is analogous to writing covered call options on
securities. The Fund also may purchase put options on securities index futures
contracts. The purchase of put options on securities index futures contracts is
analogous to the purchase of protective put options on individual securities
where a level of protection is sought below which no additional economic loss
would be incurred by the Fund.

         The Fund may also purchase and sell futures contracts on a foreign
currency. The Fund may sell a foreign currency futures contract to hedge against
possible variations in the exchange rate of the foreign currency in relation to
the U.S. dollar that could adversely affect the market values of the Fund's
foreign securities holdings. In this case, the sale of futures contracts on the
underlying currency may reduce the risk to the Fund caused by foreign currency
variations and, by so doing, provide an alternative to the liquidation of
securities positions in the Fund and resulting transaction costs. When the
Adviser anticipates a significant foreign exchange rate increase while intending
to invest in a security denominated in a foreign currency, the Fund may purchase
a foreign currency futures contract to hedge against a rise in foreign exchange
rates pending completion of the anticipated transaction. Such a purchase would
serve as a temporary measure to protect the Fund against any additional costs to
acquiring the foreign security position.

         The Fund may also purchase call or put options on foreign currency
futures contracts to obtain a fixed foreign exchange rate at limited risk. The
Fund may purchase a call option on a foreign currency futures

                                       14

<PAGE>



contract to hedge against a rise in the foreign exchange rate while intending to
invest in a foreign security of the same currency. The Fund may purchase put
options on foreign currency futures contracts as a hedge against a decline in
the foreign exchange rates or the value of its foreign portfolio securities. It
may also write a call option on a foreign currency futures contract as a partial
hedge against the effects of declining foreign exchange rates on the value of
foreign securities. The Fund may sell a put option on a foreign currency to
partially offset an increase in the cost of a security denominated in that
currency that the Fund anticipates purchasing; however, the cost will only be
offset to the extent of the premium received by the Fund for writing the option.

         The Fund may also write put options on interest rate, securities index
or foreign currency futures contracts while, at the same time, purchasing call
options on the same interest rate, securities index or foreign currency futures
contract in order synthetically to create a long futures contract position. The
options will have the same strike prices and expiration dates. The Fund will
engage in this strategy only when its Adviser believes it is more advantageous
to the Fund to do so as compared to purchasing the futures contract.

         The Fund may also purchase and write covered straddles on interest
rate, foreign currency or securities index futures contracts. A long straddle is
a combination of a call and a put purchased on the same futures contract where
the exercise price of the put option is less than the exercise price of the call
option. The Fund would enter into a long straddle when it believes that it is
likely that interest rates or foreign currency exchange rates will be more
volatile during the term of the options than the option pricing implies. A short
straddle is a combination of a call and put written on the same futures contract
where the exercise price of the put option is less than the exercise price of
the call option. In a covered short straddle, the same futures contract is
considered "cover" for both the put and the call that the Fund has written. The
Fund would enter into a short straddle when it believes that it is unlikely that
interest rates or foreign currency exchange rates will be as volatile during the
term of the options as the option pricing implies. In such case, the Fund will
set aside cash or appropriate liquid, high grade debt securities in a segregated
account with its custodian equal in value to the amount, if any, by which the
put is "in-the-money", that is, the amount by which the exercise price of the
put exceeds the current market value of the underlying futures contract.

         When a purchase or sale of a futures contract is made by the Fund, the
Fund is required to deposit with its custodian (or a broker, if legally
permitted) a specified amount of cash or U.S. Government securities ("initial
margin"). The margin required for a futures contract is set by the exchange on
which the contract is traded. The initial margin is in the nature of a
performance bond or good faith deposit on the futures contract, which is
returned to the Fund upon termination of the contract assuming all contractual
obligations have been satisfied. Under certain circumstances, such as periods of
high volatility, the Fund may be required by an exchange to increase the level
of its initial margin payment. Additionally, initial margin requirements may be
increased generally in the future by regulatory action. The Fund expects to earn
interest income on its initial margin deposits. A futures contract held by the
Fund is valued daily at the official settlement price of the exchange on which
it is traded. Each day the Fund pays or receives cash, called "variation
margin," equal to the daily change in value of the futures contract. This
process is known as "marking-to-market." Variation margin does not represent a
borrowing or loan by the Fund but is instead settlement between the Fund and the
broker of the amount one would owe the other if the futures contract had expired
on that date. In computing daily net asset value, the Fund will mark-to-market
its open futures positions.

         The Fund is also required to deposit and maintain margin with respect
to put and call options on futures contracts and on certain foreign currencies
written by it. Such margin deposits will vary depending on the nature of the
underlying futures contract or currency (and the related initial margin
requirements), the current market value of the option and other options and
futures positions held by the Fund.

         Although some futures contracts call for making or taking delivery of
the underlying securities, generally futures contracts are closed out prior to
delivery by offsetting purchases or sales of matching futures

                                       15

<PAGE>



contracts (involving the same currency, index or underlying security and
delivery month). If an offsetting purchase price is less than the original sale
price, the Fund realizes a gain, or if it is more, the Fund realizes a loss. If
an offsetting sale price is more than the original purchase price, the Fund
realizes a gain, or if it is less, the Fund realizes a loss. The Fund will also
bear transaction costs for each contract, which must be considered in these
calculations.

         The Fund will not enter into futures contracts or commodities option
positions other than for bona fide hedging purposes if, immediately thereafter,
the initial margin deposits plus premiums paid by it, less the amount by which
any such options positions are "in-the-money" at the time of purchase, would
exceed 5% of the fair market value of the Fund's net assets. A call option is
"in-the-money" if the value of the futures contract that is the subject of the
option exceeds the exercise price. A put option is "in-the-money" if the
exercise price exceeds the value of the futures contract that is the subject of
the option. Foreign currency options traded on a commodities exchange are
considered commodity options for this purpose.

Risks Associated with Futures and Options
- -----------------------------------------

         In considering the Fund's use of futures contracts and options,
particular note should be taken of the following:

         (1) Positions in futures contracts may be closed out only on an
exchange or board of trade that provides a secondary market for such futures
contracts. Futures exchanges may limit the amount of fluctuation permitted in
certain futures contract prices during a single trading day. The daily limit
establishes the maximum amount that the price of a futures contract may vary
either up or down from the previous day's settlement price at the end of the
current trading session. Once the daily limit has been reached in a futures
contract subject to the limit, no more trades may be made on that day at a price
beyond that limit. The daily limit governs only price movements during a
particular trading day and therefore does not limit potential losses because the
limit may work to prevent the liquidation of unfavorable positions. For example,
futures prices have occasionally moved to the daily limit for several
consecutive trading days with little or no trading, thereby preventing prompt
liquidation of positions and subjecting some holders of futures contracts to
substantial losses.

         (2) The ability to establish and close out positions in either futures
contracts or options is subject to the maintenance of a liquid secondary market.
There is no assurance that a liquid secondary market will exist for any
particular futures contract or option at any specific time. Consequently, it may
not be possible for the Fund to close a position and, in the event of adverse
price movements, the Fund would have to make daily cash payments of variation
margin (in the case of futures and options written thereon). However, in the
event futures contracts or options have been used to hedge portfolio securities,
such securities will not be sold until the contracts can be terminated. In such
circumstances, an increase in the price of the securities, if any, may partially
or completely offset losses on the futures contract. However, there is no
guarantee that the price of the securities will, in fact, correlate with the
price movements in the contracts and thus provide an offset to losses on the
contracts.

         (3) Successful use by the Fund of futures contracts and options will
depend upon the Adviser's ability to predict movements in the direction of the
overall securities, currency and interest rate markets, which may require
different skills and techniques than predicting changes in the prices of
individual securities. Moreover, futures contracts relate not to the current
level of the underlying instrument but to the anticipated level at some point in
the future. There is, in addition, the risk that the movements in the price of
the futures contract will not correlate with the movements in prices of the
securities or currencies being hedged. For example if the price of the futures
contract moves less than the price of the securities or currencies that are
subject to the hedge, the hedge will not be fully effective; however, if the
price of securities or currencies being hedged has moved in an unfavorable
direction, the Fund would be in a better position than if it had not hedged

                                       16

<PAGE>



at all. If the price of the securities or currencies being hedged has moved in a
favorable direction, this advantage may be partially offset by losses in the
futures position. In addition, if the Fund has insufficient cash, it may have to
sell assets from its investment portfolio to meet daily variation margin
requirements. Any such sale of assets may or may not be made at prices that
reflect the rising market; consequently, the Fund may need to sell assets at a
time when such sales are disadvantageous to the Fund. If the price of the
futures contract moves more than the price of the underlying securities or
currencies, the Fund will experience either a loss or a gain on the futures
contract that may or may not be completely offset by movements in the price of
the securities or currencies that are the subject of the hedge.

         (4) The value of an option position will reflect, among other things,
the current market price of the underlying security, index, futures contract or
currency, the time remaining until expiration, the relationship of the exercise
price to the market price, the historical price volatility of the underlying
security, index, futures contract or currency and general market conditions.

         (5) Movements in the prices of futures contracts may not correlate
perfectly with movements in the prices of the hedged securities or currencies
due to price distortions in the futures market. There may be several reasons
unrelated to the value of the underlying securities or currencies that cause
this situation to occur. First, as noted above, all participants in the futures
market are subject to initial and variation margin requirements. If, to avoid
meeting additional margin deposit requirements or for other reasons, investors
choose to close a significant number of futures contracts through offsetting
transactions, distortions in the normal price relationship between the
securities or currencies and the futures markets may occur. Second, because the
margin deposit requirements in the futures market are less onerous than margin
requirements in the securities market, there may be increased participation by
speculators in the futures market; such speculative activity in the futures
market also may cause temporary price distortions. Third, participants could
make or take delivery of the underlying securities or currencies instead of
closing out their contracts. As a result, a correct forecast of general market
trends may not result in successful hedging through the use of futures contracts
over the short term. In addition, activities of large traders in both the
futures and securities markets involving arbitrage and other investment
strategies may result in temporary price distortions.

         (6) Options normally have expiration dates of up to three years. The
exercise price of the options may be below, equal to or above the current market
value of the underlying security, index, futures contract or currency. Purchased
options that expire unexercised have no value, and the Fund will realize a loss
in the amount paid plus any transaction costs.

         (7) Purchasers of options on futures contracts pay a premium in cash at
the time of purchase. This amount and the transaction costs are all that is at
risk. Sellers of options on futures contracts, however, must post an initial
margin and are subject to additional margin calls that could be substantial in
the event of adverse price movements. In addition, although the maximum amount
at risk when the Fund purchases an option is the premium paid for the option and
the transaction costs, there may be circumstances when the purchase of an option
on a futures contract would result in a loss to the Fund but the use of a
futures contract would not, such as when there is no movement in the value of
the securities or currencies being hedged.

         (8) The Fund's activities in the futures and options markets may result
in a higher portfolio turnover rate and additional transaction costs in the form
of added brokerage commissions; however, the Fund also may save on commissions
by using such contracts as a hedge rather than buying or selling individual
securities or currencies in anticipation or as a result of market movements.

         (9) Closing transactions may be effected with respect to options traded
in the OTC markets (currently the primary markets for options on debt securities
and foreign currencies) only by negotiating directly with the other party to the
option contract, or in a secondary market for the option if such market exists.
Although the Fund will enter into OTC options only with dealers that agree to
enter into, and that are

                                       17

<PAGE>



expected to be capable of entering into, closing transactions with the Fund,
there can be no assurance that the Fund will be able to liquidate an OTC option
at a favorable price at any time prior to expiration. In the event of insolvency
of the contra-party, the Fund may be unable to liquidate an OTC option. With
respect to options written by the Fund, the inability to enter into a closing
transaction may result in material losses to the Fund. For example, because the
Fund must maintain a covered position with respect to any call option it writes
on a security, futures contract or currency, the Fund may not sell the
underlying security, futures contract or currency or invest any cash or
appropriate liquid securities used as cover during the period it is obligated
under such option. This requirement may impair the Fund's ability to sell a
portfolio security or make an investment at a time when such a sale or
investment might be advantageous.

         (10) Securities index options are settled exclusively in cash. If the
Fund purchases a put or call option on an index, the Fund will not know in
advance the difference, if any, between the closing value of the index on the
exercise date and the exercise price of the option itself. Thus, if the Fund
exercises a securities index option before the closing index value for that day
is available, the Fund runs the risk that the level of the underlying index may
subsequently change.

Special Risks Related to Foreign Currency Futures Contracts and Options on Such
- -------------------------------------------------------------------------------
Contracts and Options on Foreign Currencies
- -------------------------------------------

         Buyers and sellers of foreign currency futures contracts are subject to
the same risks that apply to the use of futures generally. In addition, there
are risks associated with foreign currency futures contracts and their use as a
hedging device similar to those associated with options on foreign currencies
described below. Further, settlement of a foreign currency futures contract may
be required to occur within the country issuing the underlying currency. Thus,
the Fund must accept or make delivery of the underlying foreign currency in
accordance with any U.S. or foreign restrictions or regulations regarding the
maintenance of foreign banking arrangements by U.S. residents and may be
required to pay any fees, taxes or charges associated with such delivery that
are assessed in the issuing country.

         Options on foreign currency futures contracts may involve certain
additional risks. The ability to establish and close out positions in such
options is subject to the maintenance of a liquid secondary market. To reduce
this risk, the Fund will not purchase or write options on foreign currency
futures contracts unless and until, in the opinion of the Adviser, the market
for such options has developed sufficiently that the risks in connection with
such options are not greater than the risks in connection with transactions in
the underlying foreign currency futures contracts. Compared to the purchase or
sale of foreign currency futures contracts, the purchase of call or put options
on futures contracts involves less potential risk to the Fund because the
maximum amount at risk is the premium paid for the option (plus transaction
costs). However, there may be circumstances when the purchase of a call or put
option on a foreign currency futures contract would result in a loss, such as
when there is no movement in the price of the underlying currency or futures
contract, but the purchase of the underlying futures contract would not result
in a loss.

         The value of a foreign currency option depends upon the value of the
underlying currency relative to the U.S. dollar. As a result, the price of the
option position may vary with changes in the value of either or both currencies
and may have no relationship to the investment merits of a foreign security.
Because foreign currency transactions occurring in the interbank market involve
substantially larger amounts than those that may be involved in the use of
foreign currency options, investors may be disadvantaged by having to deal in an
odd lot market (generally consisting of transactions of less than $1 million)
for the underlying foreign currencies at prices that are less favorable than for
round lots.

         There is no systematic reporting of last sale information for foreign
currencies or any regulatory requirement that quotations available through
dealers or other market sources be firm or revised on a timely basis. Quotation
information available is generally representative of very large transactions in
the interbank

                                       18

<PAGE>



market and thus may not reflect relatively smaller transactions (i.e., less than
$1 million) where rates may be less favorable. The interbank market in foreign
currencies is a global, around-the-clock market. To the extent that the U.S.
options markets are closed while the markets for the underlying currencies
remain open, significant price and rate movements may take place in the
underlying markets that cannot be reflected in the options markets until they
reopen.

Additional Risks of Options on Securities, Futures Contracts, Options on Futures
- --------------------------------------------------------------------------------
and Forward Currency Exchange Contracts and Options Thereon Traded on Foreign
- -----------------------------------------------------------------------------
Exchanges
- ---------

         Options on securities, futures contracts, options on futures contracts,
currencies and options on currencies may be traded on foreign exchanges. Such
transactions may not be regulated as effectively as similar transactions in the
United States, may not involve a clearing mechanism and related guarantees and
are subject to the risk of governmental actions affecting trading in, or the
price of, foreign securities. The value of such positions also could be
adversely affected by (1) other complex foreign political, legal and economic
factors, (2) lesser availability than in the United States of data on which to
make trading decisions, (3) delays in the Fund's ability to act upon economic
events occurring in foreign markets during non-business hours in the United
States, (4) the imposition of different exercise and settlement terms and
procedures and margin requirements than in the United States and (5) lesser
trading volume.

Forward Contracts
- -----------------

         The Fund may use forward currency exchange contracts ("forward
contracts") to hedge against uncertainty in the level of future exchange rates.

         The Fund may enter into forward contracts with respect to specific
transactions. For example, when the Fund anticipates purchasing or selling a
security denominated in a foreign currency, or when it anticipates the receipt
in a foreign currency of dividend or interest payments on a security that it
holds, the Fund may desire to "lock in" the U.S. dollar price of the security or
the U.S. dollar equivalent of such payment, as the case may be, by entering into
a forward contract for the purchase or sale, for a fixed amount of U.S. dollars
or foreign currency, of the amount of foreign currency involved in the
underlying transaction. The Fund will thereby attempt to protect itself against
a possible loss resulting from an adverse change in the relationship between the
currency exchange rates during the period between the date on which the security
is purchased or sold, or on which the payment is declared, and the date on which
such payments are made or received.

         The Fund also may use forward contracts to "lock in" the U.S. dollar
value of its portfolio positions, to increase the Fund's exposure to foreign
currencies that the Adviser believes may rise in value relative to the U.S.
dollar or to shift the Fund's exposure to foreign currency fluctuations from one
country to another. For example, when the Adviser believes that the currency of
a particular foreign country may suffer a substantial decline relative to the
U.S. dollar or another currency, it may enter into a forward contract to sell
the amount of the former foreign currency approximating the value of some or all
of the Fund's securities denominated in such foreign currency. These investment
practices generally are referred to as "cross-currency hedging" when two foreign
currencies are involved.

         At or before the maturity date of a forward contract requiring the Fund
to sell a currency, the Fund may either sell a portfolio security and use the
sale proceeds to make delivery of the currency or retain the security and offset
its contractual obligation to deliver the currency by purchasing a second
contract pursuant to which the Fund will obtain, on the same maturity date, the
same amount of the currency that it is obligated to deliver. Similarly, the Fund
may close out a forward contract requiring it to purchase a specified currency
by entering into a second contract entitling it to sell the same amount of the
same currency on the maturity date of the first contract. The Fund would realize
a gain or loss as a result of entering into such an offsetting forward contract

                                       19

<PAGE>



under either circumstance to the extent the exchange rate between the currencies
involved moved between the execution dates of the first contract and the
offsetting contract.

         The precise matching of the forward contract amount and the value of
the securities involved will not generally be possible because the future value
of such securities in foreign currencies will change as a consequence of market
movements in the value of those securities between the date the forward contract
is entered into and the date it matures. Accordingly, it may be necessary for
the Fund to purchase additional foreign currency on the spot (i.e., cash) market
(and bear the expense of such purchase) if the market value of the security is
less than the amount of foreign currency the Fund is obligated to deliver and if
a decision is made to sell the security and make delivery of the foreign
currency. Conversely, it may be necessary to sell on the spot market some of the
foreign currency received upon the sale of the portfolio security if its market
value exceeds the amount of foreign currency the Fund is obligated to deliver.

         The projection of short-term currency market movements is extremely
difficult, and the successful execution of a short-term hedging strategy is
highly uncertain. Forward contracts involve the risk that currency movements
will not be accurately predicted, causing the Fund to sustain losses on these
contracts and transaction costs. The Fund may enter into forward contracts or
maintain a net exposure to such contracts only if (1) the consummation of the
contracts would not obligate the Fund to deliver an amount of foreign currency
in excess of the value of the Fund's portfolio securities or other assets
denominated in that currency or (2) the Fund maintains cash or appropriate
liquid securities in a segregated account with the Fund's custodian,
marked-to-market daily, in an amount not less than the value of the Fund's total
assets committed to the consummation of the contract. Under normal
circumstances, consideration of the prospect for currency parities will be
incorporated into the longer-term investment decisions made with regard to
overall diversification strategies. However, the Adviser believes that it is
important to have the flexibility to enter into such forward contracts when it
determines that the best interests of the Fund will be served.

         The cost to the Fund of engaging in forward contracts varies with
factors such as the currencies involved, the length of the contract period and
the market conditions then prevailing. Because forward contracts are usually
entered into on a principal basis, no fees or commissions are involved. The use
of forward contracts does not eliminate fluctuations in the prices of the
underlying securities the Fund owns or intends to acquire, but it does fix a
rate of exchange in advance. In addition, although forward contracts limit the
risk of loss due to a decline in the value of the hedged currencies, at the same
time, they limit any potential gain that might result should the value of the
currencies increase.

         Although the Fund values its assets daily in terms of U.S. dollars, it
does not intend to convert its holdings of foreign currencies into U.S. dollars
on a daily basis. The Fund may convert foreign currency from time to time, and
investors should be aware of the costs of currency conversion. Although foreign
exchange dealers do not charge a fee for conversion, they do realize a profit
based on the difference between the prices at which they are buying and selling
various currencies. Thus, a dealer may offer to sell a foreign currency to the
Fund at one rate, while offering a lesser rate of exchange should the Fund
desire to resell that currency to the dealer.

Foreign Currency Warrants
- -------------------------

         Foreign currency warrants entitle the holder to receive from their
issuer an amount of cash (generally, for warrants issued in the United States,
in U.S. dollars) that is calculated pursuant to a predetermined formula and
based on the exchange rate between a specified foreign currency and the U.S.
dollar as of the exercise date of the warrant. Foreign currency warrants
generally are exercisable upon their issuance and expire as of a specified date
and time. Foreign currency warrants have been issued in connection with U.S.
dollar-denominated debt offerings by major corporate issuers in an attempt to
reduce the foreign currency exchange risk that is inherent in the international
fixed income/debt marketplace. The formula used to determine the

                                       20

<PAGE>



amount payable upon exercise of a foreign currency warrant may make the warrant
worthless unless the applicable foreign currency exchange rate moves in a
particular direction.

         Foreign currency warrants are severable from the debt obligations with
which they may be offered and may be listed on exchanges. Foreign currency
warrants may be exercisable only in certain minimum amounts, and an investor
wishing to exercise warrants who possesses less than the minimum number required
for exercise may be required either to sell the warrants or to purchase
additional warrants, thereby incurring additional transaction costs. In the case
of any exercise of warrants, there may be a time delay between the time a holder
of warrants gives instructions to exercise and the time the exchange rate
relating to exercise is determined, during which time the exchange rate could
change significantly, thereby affecting both the market and cash settlement
values of the warrants being exercised.

         The expiration date of the warrants may be accelerated if the warrants
are delisted from an exchange or if their trading is suspended permanently,
which would result in the loss of any remaining "time value" of the warrants
(i.e., the difference between the current market value and the exercise value of
the warrants) and, in the case where the warrants were "out-of-the-money," in a
total loss of the purchase price of the warrants. Warrants are generally
unsecured obligations of their issuers and are not standardized foreign currency
options issued by the Options Clearing Corporation ("OCC"). Unlike foreign
currency options issued by OCC, the terms of foreign currency warrants generally
will not be amended in the event of governmental or regulatory actions affecting
exchange rates or in the event of the imposition of other regulatory controls
affecting the international currency markets. The initial public offering price
of foreign currency warrants is generally considerably in excess of the price
that a commercial user of foreign currencies might pay in the interbank market
for a comparable option involving significantly larger amounts of foreign
currencies. Foreign currency warrants are subject to significant foreign
exchange risk, including risks arising from complex political and economic
factors.

Cover for Strategies Involving Options, Futures and Forward Contracts
- ---------------------------------------------------------------------

         The Fund will not use leverage in its options, futures and forward
contract strategies. The Fund will not enter into an options, futures or forward
currency strategy that exposes it to an obligation to another party unless it
owns either (1) an offsetting ("covering") position in securities, currencies or
other options, futures or forward contracts or (2) cash, receivables and
appropriate liquid securities with a value sufficient to cover its potential
obligations. The Fund will comply with guidelines established by the SEC with
respect to coverage of these strategies by mutual funds, and, if the guidelines
so require, will set aside cash and/or appropriate liquid securities in a
segregated account with its custodian in the amount prescribed, as marked-
to-market daily. Securities, currencies or other options, futures or forward
positions used for cover and securities held in a segregated account cannot be
sold or closed out while the strategy is outstanding, unless they are replaced
with similar assets. As a result, there is a possibility that the use of cover
or segregation involving a large percentage of the Fund's assets could impede
portfolio management or the Fund's ability to meet redemption requests or other
current obligations.

   
    

OTHER INVESTMENT POLICIES
- -------------------------
The following investment policies apply only to Government Intermediate,
Investment Grade and High Yield unless otherwise stated:

         ILLIQUID SECURITIES   SEC Rule 144A permits the sale of certain
restricted securities to qualified institutional buyers. The Adviser, acting
pursuant to guidelines established by the Board of Directors, may

                                       21

<PAGE>



determine that certain restricted securities qualified for trading on this newly
developing market are liquid. If the market does not develop as anticipated, it
may adversely affect each Fund's liquidity.

   
         MUNICIPAL OBLIGATIONS Municipal obligations also include municipal
lease obligations. These obligations, which are issued by state and local
governments to acquire land, equipment and facilities, typically are not fully
backed by the municipality's credit, and, if funds are not appropriated for the
following year's lease payments, a lease may terminate, with the possibility of
default on the lease obligation and significant loss to a Fund. The two
principal classifications of municipal obligations are "general obligation" and
"revenue" bonds. "General obligation" bonds are secured by the issuer's pledge
of its faith, credit and taxing power. "Revenue" bonds are payable only from the
revenues derived from a particular facility or class of facilities or from the
proceeds of a special excise tax or other specific revenue source such as the
corporate user of the facility being financed. Industrial development bonds
("IDBs") and private activity bonds ("PABs") are usually revenue bonds and are
not payable from the unrestricted revenues of the issuer. The credit quality of
the IDBs and PABs is usually directly related to the credit standing of the
corporate user of the facilities. In addition, certain types of IDBs and PABs
are issued by or on behalf of public authorities to finance various privately
operated facilities, including certain pollution control facilities, convention
or trade show facilities, and airport, mass transit, port or parking facilities.
    

         PRIVATE PLACEMENTS Each Fund may acquire restricted securities in
private placement transactions, directly from the issuer or from security
holders, frequently at higher yields than comparable publicly traded securities.
Privately-placed securities can be sold by each Fund only (1) pursuant to SEC
Rule 144A or other exemption; (2) in privately negotiated transactions to a
limited number of purchasers; or (3) in public offerings made pursuant to an
effective registration statement under the 1933 Act. Private or public sales of
such securities by a Fund may involve significant delays and expense. Private
sales require negotiations with one or more purchasers and generally produce
less favorable prices than the sale of comparable unrestricted securities.
Public sales generally involve the time and expense of preparing and processing
a registration statement under the 1933 Act and may involve the payment of
underwriting commissions; accordingly, the proceeds may be less than the
proceeds from the sale of securities of the same class which are freely
marketable.

RESTRICTIONS: Restricted securities will not be purchased by either Government
Intermediate or Investment Grade if, as a result, more than 5% of that Fund's
assets would consist of restricted securities.

         SECURITIES LENDING (APPLIES TO ALL OF THE FUNDS) Each Fund may lend
portfolio securities to brokers or dealers in corporate or U.S. government
securities (U.S. government securities only, with respect to Government
Intermediate and Government Money Market), banks or other recognized
institutional borrowers of securities, provided that the borrower maintains cash
or equivalent collateral, equal to at least 100% of the market value of the
securities loaned with the Funds' custodian. During the time portfolio
securities are on loan, the borrower will pay the lending Fund an amount
equivalent to any interest paid on such securities, and the Fund may invest the
cash collateral and earn income, or it may receive an agreed upon amount of
interest income from the borrower who has delivered equivalent collateral. These
loans are subject to termination at the option of the Fund or the borrower. Each
Fund may pay reasonable administrative and custodial fees in connection with a
loan and may pay a negotiated portion of the interest earned on the cash or
equivalent collateral to the borrower or placing broker. In the event of the
bankruptcy of the other party to a securities loan, a Fund could experience
delays in recovering the securities lent. To the extent that, in the meantime,
the value of the collateral had decreased or the securities lent increased, the
Fund could experience a loss. Each Fund will enter into securities loan
transactions only with financial institutions which the Adviser believes to
present minimal risk of default during the term of the loan. Each Fund does not
have the right to vote securities on loan, but would terminate the loan and
regain the right to vote if that were considered important with respect to the
investment. Each Fund presently does not intend to loan more than 5% of its
portfolio securities at any given time.

                                       22

<PAGE>



         REPURCHASE AGREEMENTS (APPLIES TO ALL OF THE FUNDS) Repurchase
agreements are usually for periods of one week or less, but may be for longer
periods. Repurchase agreements maturing in more than seven days may be
considered illiquid. In a repurchase agreement, the securities are held for each
Fund by a custodian bank as collateral until resold and are supplemented by
additional collateral if necessary to maintain a total value equal to or in
excess of the value of the repurchase agreement. Each Fund bears a risk of loss
in the event that the other party to a repurchase agreement defaults on its
obligations and a Fund is delayed or prevented from exercising its rights to
dispose of the collateral securities. Each Fund enters into repurchase
agreements only with financial institutions which the Adviser believes present
minimal risk of default during the term of the agreement based on guidelines
established by the Corporation's Board of Directors. Each Fund currently intends
to invest in repurchase agreements only when cash is temporarily available or
for temporary defensive purposes.

         REVERSE REPURCHASE AGREEMENTS (APPLIES TO ALL OF THE FUNDS) A reverse
repurchase agreement is a portfolio management technique in which a Fund
temporarily transfers possession of a portfolio instrument to another person,
such as a financial institution or broker-dealer, in return for cash. At the
same time, the Fund agrees to repurchase the instrument at an agreed upon time
(normally within seven days) and price, including interest payment. Each Fund
(other than Government Money Market) may also enter into dollar rolls, in which
a Fund sells a fixed income security for delivery in the current month and
simultaneously contracts to repurchase a substantially similar security (same
type, coupon and maturity) on a specified future date. During the roll period,
that Fund would forgo principal and interest paid on such securities. The Fund
would be compensated by the difference between the current sales price and the
forward price for the future purchase, as well as by any interest earned on the
proceeds of the initial sale.

         Each Fund may engage in reverse repurchase agreements and (with the
exception of Government Money Market) dollar rolls as a means of raising cash to
satisfy redemption requests or for other temporary or emergency purposes without
the necessity of selling portfolio instruments. There is a risk that the
contraparty to either a reverse repurchase agreement or a dollar roll will be
unable or unwilling to complete the transaction as scheduled, which may result
in losses to a Fund.

         When a Fund reinvests the proceeds of a reverse repurchase agreement in
other securities, any fluctuations in the market value of either the securities
transferred to another party or the securities in which the proceeds are
invested would affect the market value of that Fund's assets. If a Fund
reinvests the proceeds of the agreement at a rate lower than the cost of the
agreement, engaging in the agreement will lower that Fund's yield. While
engaging in reverse repurchase agreements and dollar rolls, each Fund will
maintain cash, U.S. Government securities (or other appropriate liquid
securities, with respect to Investment Grade and High Yield) in a segregated
account at its custodian bank with a value at least equal to that Fund's
obligation under the agreements.

RESTRICTIONS: The ability of a Fund to engage in reverse repurchase agreements
and/or dollar rolls is subject to each Fund's fundamental investment limitation
concerning borrowing, i.e., that borrowing may be for temporary purposes only
and in an amount not to exceed 5% of a Fund's total assets.

         WARRANTS Although not a fundamental policy subject to shareholder vote,
as long as each Fund's shares continue to be registered in certain states, each
Fund may not invest more than 5% of the value of its net assets, taken at the
lower of cost or market value, in warrants or invest more than 2% of the value
of such net assets in warrants not listed on the New York or American Stock
Exchanges. With respect to High Yield, this restriction does not apply to
warrants attached to, or sold as a unit with, other securities. For purposes of
this restriction, the term "warrants" does not include options on securities,
stock or bond indices, foreign currencies or futures contracts.


                                       23

<PAGE>



         MORTGAGE-RELATED SECURITIES Mortgage-related securities represent an
ownership interest in a pool of residential mortgage loans. These securities are
designed to provide monthly payments of interest, and in most instances,
principal to the investor. The mortgagor's monthly payments to his/her lending
institution are "passed-through" to investors such as a Fund. Most issuers or
poolers provide guarantees of payments, regardless of whether or not the
mortgagor actually makes the payment. The guarantees made by issuers or poolers
are backed by various forms of credit, insurance and collateral. They may not
extend to the full amount of the pool.

         Pools consist of whole mortgage loans or participations in loans. The
majority of these loans are made to purchasers of one- to four-family homes. The
terms and characteristics of the mortgage instruments are generally uniform
within a pool but may vary among pools. For example, in addition to fixed-rate,
fixed-term mortgages, a Fund may purchase pools of variable-rate mortgages,
growing-equity mortgages, graduated-payment mortgages and other types.

         All poolers apply standards for qualification to lending institutions
which originate mortgages for the pools. Poolers also establish credit standards
and underwriting criteria for individual mortgages included in the pools. In
addition, many mortgages included in pools are insured through private mortgage
insurance companies.

   
         The majority of mortgage-related securities currently available are
issued by governmental or government-related organizations formed to increase
the availability of mortgage credit. The largest government-sponsored issuer of
mortgage-related securities is GNMA. GNMA certificates ("GNMAs") are interests
in pools of loans insured by the Federal Housing Administration or by the
Farmer's Home Administration ("FHA"), or guaranteed by the Veterans
Administration ("VA"). Fannie Mae and Freddie Mac each issue pass-through
securities which are guaranteed as to principal and interest by Fannie Mae and
Freddie Mac, respectively.

         The average life of mortgage-related securities varies with the
maturities and the nature of the underlying mortgage instruments. For example,
GNMAs tend to have a longer average life than Freddie Mac participation
certificates ("PCs") because there is a tendency for the conventional and
privately- insured mortgages underlying Freddie MacPCs to repay at faster rates
than the FHA and VA loans underlying GNMAs. In addition, the term of a security
may be shortened by unscheduled or early payments of principal and interest on
the underlying mortgages. The occurrence of mortgage pre-payments is affected by
various factors, including the level of interest rates, general economic
conditions, the location and age of the mortgaged property and other social and
demographic conditions.
    

         In determining the dollar-weighted average maturity of a Fund's
portfolio, the Adviser will follow industry practice in assigning an average
life to the mortgage-related securities of the Fund unless the interest rate on
the mortgages underlying such securities is such that a different prepayment
rate is likely. For example, where a GNMA has a high interest rate relative to
the market, that GNMA is likely to have a shorter overall maturity than a GNMA
with a market rate coupon. Moreover, the Adviser may deem it appropriate to
change the projected average life for a Fund's mortgage-related security as a
result of fluctuations in market interest rates and other factors.

         Quoted yields on mortgage-related securities are typically based on the
maturity of the underlying instruments and the associated average life
assumption. Actual prepayment experience may cause the yield to differ from the
average life yield. Reinvestment of the prepayments may occur at higher or lower
interest rates than the original investment, thus affecting the yield of the
Fund. The compounding effect from the reinvestments of monthly payments received
by the Fund will increase the yield to shareholders compared to bonds that pay
interest semi-annually.

                                       24

<PAGE>



         Like other debt securities, the value of mortgage-related securities
will tend to rise when interest rates fall, and fall when rates rise. The value
of mortgage-related securities may also change because of changes in the
market's perception of the creditworthiness of the organization that issued or
guaranteed them. In addition, the mortgage securities market in general may be
adversely affected by changes in governmental regulation or tax policies.

         STEP DOWN PREFERRED SECURITIES Some of the securities purchased by
Investment Grade and High Yield may also include step down perpetual preferred
securities. These securities are issued by a real estate investment trust
("REIT") making a mortgage loan to a single borrower. The dividend rate paid by
these securities is initially relatively high, but steps down yearly. The stock
is subject to call if the REIT suffers an unfavorable tax event, and to tender
by the issuer's equity holder in the 10th year; both events could be on terms
unfavorable to the holder of the preferred stock. The value of this security
will be affected by changes in the value of the underlying mortgage loan. The
REIT is not diversified, and the value of the mortgaged property may not cover
its obligations. Step down perpetual preferred securities are considered
restricted securities under the Securities Act of 1933.

         ASSET-BACKED SECURITIES Asset-backed securities are structurally
similar to mortgage-backed securities, but are secured by an interest in a
different type of receivable. Asset-backed securities therefore present certain
risks that are not presented by mortgage-related debt securities or other
securities in which a Fund may invest. Primarily, these securities do not have
the benefit of the same security interest in the related collateral.
Asset-backed securities represent direct or indirect participations in, or are
secured by and payable from, pools of assets such as motor vehicle installment
sales contracts, installment loan contracts, leases of various types of real and
personal property, and receivables from revolving credit agreements. Credit card
receivables, for example, are generally unsecured and the debtors are entitled
to the protection of a number of state and federal consumer credit laws, many of
which give such debtors the right to set off certain amounts owed on the credit
cards, thereby reducing the balance due. Most issuers of automobile receivables
permit the servicers to retain possession of the underlying obligations. If the
servicer were to sell these obligations to another party, there is a risk that
the purchaser would acquire an interest superior to that of the holders of the
automobile receivables. In addition, because of the large number of vehicles
involved in a typical issuance and technical requirements under state laws, the
trustee for the holders of the automobile receivables may not have proper
security interest in all of the obligations backing such receivables. Therefore,
there is the possibility that recoveries on repossessed collateral may not, in
some cases, be available to support payments on these securities. Because
asset-backed securities are relatively new, the market experience in these
securities is limited and the market's ability to sustain liquidity through all
phases of the market cycle has not been tested.

The following investment policies apply only to High Yield:

         FOREIGN SECURITIES Since the Fund may invest in securities denominated
in currencies other than the U.S. dollar, the Fund may be affected favorably or
unfavorably by exchange control regulations or changes in the exchange rates
between such currencies and the U.S. dollar. Changes in the currency exchange
rates may influence the value of the Fund's shares, and also may affect the
value of dividends and interest earned by the Fund and gains and losses realized
by the Fund. Exchange rates are determined by the forces of supply and demand in
the foreign exchange markets. These forces are affected by the international
balance of payments and other economic and financial conditions, government
intervention, speculation and other factors.

         Foreign securities transactions could be subject to settlement
procedures different from those followed in the United States, where delivery is
made versus payment. The settlement procedures in some foreign markets expose
investors to the creditworthiness of an intermediary, such as a bank or
brokerage firm, for a period of time during settlement.

                                       25

<PAGE>



         SWAPS, CAPS, FLOORS AND COLLARS The Fund may enter into interest rate
swaps, and may purchase and sell caps, floors, and collars for hedging purposes
or in an effort to increase overall return. An interest rate swap is an exchange
of interest payment streams of differing character between counterparties with
respect to a "notional amount" of principal. Index swaps link one of the
payments to the total return of a market portfolio. A cap enables an investor,
in return for a fee, to receive payments if a predetermined interest rate,
currency rate or index value exceeds a particular level. A floor entitles the
investor to receive payments if the interest rate, currency rate or index value
falls below a predetermined level. A collar is a combination of a cap and a
floor and protects a return within a range of values.

Restrictions: The Fund does not intend to purchase swaps, caps, collars, or
floors if, as a result, more than 5% of the Fund's net assets would thereby be
placed at risk. Swaps, caps, collars and floors can be highly volatile
instruments. The value of these agreements is dependent on the ability of the
counterparty to perform and is therefore linked to the counterparty's
creditworthiness. The Fund may also suffer a loss if it is unable to terminate
an outstanding swap agreement.

         The Fund will enter into swaps, caps, collars and floors only with
parties deemed by the Adviser to present a minimal risk of default during the
period of agreement. When the Fund enters into a swap, cap, collar or floor, it
will maintain a segregated account containing cash and appropriate liquid
securities equal to the payment, if any, due to the other party; where contracts
are on a net basis, only the net payment will be segregated. The Fund regards
caps, collars and floors as illiquid, and therefore subject to the Fund's 15%
limit on illiquid securities. There can be no assurance that the Fund will be
able to terminate a swap at the appropriate time. The Fund will sell caps,
collars and floors only to close out its positions in such instruments.

         As with options and futures transactions, successful use of swap
agreements depends on the Adviser's ability to predict movements in the
direction of overall interest rate markets. There might be imperfect correlation
between the value of a swap, cap, collar or floor agreement and movements in the
underlying interest rate markets. While swap agreements can offset the potential
for loss on a position, they can also limit the opportunity for gain by
offsetting favorable price movements.

         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. Caps, collars and floors are
more recent innovations for which documentation is less standardized, and
accordingly, they are less liquid than swaps. The market for all of these
instruments is largely unregulated. Swaps, caps, collars and floors are
generally considered "derivatives."

         LOAN PARTICIPATIONS AND ASSIGNMENTS The Fund may purchase an interest
in loans originated by banks and other financial institutions. Policies of the
Fund limit the percentage of the Fund's assets that can be invested in the
securities of any one issuer, or in issuers primarily involved in one industry.
Legal interpretations by the SEC staff may require the Fund, in some instances,
to treat both the lending bank and the borrower as "issuers" of a loan
participation by the Fund. In combination, the Fund's policies and the SEC
staff's interpretations may limit the amount the Fund can invest in loan
participations.

         Although some of the loans in which the Fund invests may be secured,
there is no assurance that the collateral can be liquidated in particular cases,
or that its liquidation value will be equal to the value of the debt. Borrowers
that are in bankruptcy may pay only a small portion of the amount owed, if they
are able to pay at all. Where the Fund purchases a loan through an assignment,
there is a possibility that the Fund will, in the event the borrower is unable
to pay the loan, become the owner of the collateral. This involves certain risks
to the Fund as a property owner.

         Loans are often administered by a lead bank, which acts as agent for
the lenders in dealing with the borrower. In asserting rights against the
borrower, the Fund may be dependent on the willingness of the lead

                                       26

<PAGE>



bank to assert these rights, or upon a vote of all the lenders to authorize the
action. Assets held by the lead bank for the benefit of the Fund may be subject
to claims of the lead bank's creditors.




                           ADDITIONAL TAX INFORMATION

         The following is a general summary of certain federal tax
considerations affecting each Fund and its shareholders. Investors are urged to
consult their own tax advisers for more detailed information regarding any
federal, state or local taxes that may apply to them.

   
     GENERAL For federal tax purposes, each Fund is treated as a separate
corporation. In order to continue to qualify for treatment as a regulated
investment company ("RIC") under the Internal Revenue Code of 1986, as amended
("Code"), each Fund must distribute annually to its shareholders at least 90% of
its investment company taxable income (generally, net investment income, any net
short-term capital gain and, in the case of High Yield, any net gains from
certain foreign currency transactions) ("Distribution Requirement") and must
meet several additional requirements. For each Fund, these requirements include
the following: (1) The Fund must derive at least 90% of its gross income each
taxable year from dividends, interest, payments with respect to securities loans
and gains from the sale or other disposition of securities (or foreign
currencies in the case of High Yield), or other income (including gains from
options or futures contracts (or forward contracts in the case of High Yield))
derived with respect to its business of investing in securities (or those
currencies in the case of High Yield)("Income Requirement"); (2) at the close of
each quarter of a Fund's taxable year, at least 50% of the value of its total
assets must be represented by cash and cash items, U.S. government securities,
securities of other RICs and other securities, with those other securities
limited, in respect of any one issuer, to an amount that does not exceed 5% of
the value of the Fund's total assets; and (3) at the close of each quarter of a
Fund's taxable year, not more than 25% of the value of its total assets may be
invested in securities (other than U.S. government securities or the securities
of other RICs) of any one issuer.
    

         Each Fund will be subject to a nondeductible 4% excise tax ("Excise
Tax") to the extent it fails to distribute by the end of any calendar year
substantially all of its ordinary income for that year and capital gain net
income for the one-year period ending on October 31 of that year, plus certain
other amounts. For this and other purposes, dividends and other distributions
declared by a Fund in December of any year and payable to shareholders of record
on a date in that month will be deemed to have been paid by that Fund and
received by the shareholders on December 31 if the distributions are paid by the
Fund during the following January. Accordingly, those dividends and other
distributions will be taxed to the shareholders for the year in which that
December 31 falls.

   
The following applies only to Government Intermediate, Investment Grade and High
Yield:
    

         If Fund shares are sold at a loss after being held for six months or
less, the loss will be treated as a long-term, instead of a short-term, capital
loss to the extent of any capital gain distributions received on those shares.
Investors also should be aware that if shares are purchased shortly before the
record date for any

                                       27

<PAGE>



dividend or other distribution, the investor will pay full price for the shares
and receive some portion of the price back as a taxable distribution.

   
         Dividends and interest received by a Fund, and gains realized thereby,
may be subject to income, withholding or other taxes imposed by foreign
countries and U.S. possessions that would reduce the yield and/or total return
on its securities. Tax conventions between certain countries and the United
States may reduce or eliminate these foreign taxes, however, and many foreign
countries do not impose taxes on capital gains in respect of investments by
foreign investors.

         HEDGING INSTRUMENTS The use of hedging instruments, such as writing
(selling) and purchasing options, futures contracts and, in the case of High
Yield, entering into forward contracts, involves complex rules that will
determine for income tax purposes the amount, character and timing of
recognition of the gains and losses a Fund realizes in connection therewith.
Gains from High Yield's disposition of foreign currencies (except certain gains
that may be excluded by future regulations), and gains from options, futures
and, in the case of High yield, forward currency contracts derived with respect
to its business of investing in securities (or, in the case of High Yield,
foreign currencies) will qualify as permissible income under the Income
Requirement.
    

   
    

   
         Certain futures and foreign currency contracts in which a Fund may
invest will be "section 1256 contracts." Section 1256 contracts held by a Fund
at the end of each taxable year, other than section 1256 contracts that are part
of a "mixed straddle" with respect to which the Fund has made an election not to
have the following rules apply, must be "marked-to-market" (that is, treated as
having been sold for their fair market value) for federal income tax purposes,
with the result that unrealized gains or losses will be treated as though they
were realized. Sixty percent of any net gain or loss recognized on these deemed
sales, and 60% of any net realized gain or loss from any actual sales of section
1256 contracts, will be treated as long-term capital gain or loss, and the
balance will be treated as short-term capital gain or loss. As of the date of
this Statement of Additional Information, it is not entirely clear whether that
60% portion will qualify for the reduced maximum tax rates on noncorporate
taxpayers' net capital gain (i.e., the excess of net long-term capital gain over
net short-term capital gain over net short-term capital loss) enacted by the
Taxpayer Relief Act of 1997 -- 20% (10% for taxpayers in the 15% marginal tax
bracket) for gain recognized on capital assets held for more than 18 months --
instead of the 28% rate in effect before that legislation, which now applies to
gain recognized on capital assets held for more than one year but not more than
18 months. However, technical corrections legislation passed by the House of
Representatives late in 1997 would clarify that the lower rates apply. Section
1256 contracts also may be marked-to-market for purposes of the Excise Tax.
    

                                       28


<PAGE>


   
    

   
         Code section 1092 (dealing with straddles) also may affect the taxation
of options and futures contracts in which a Fund may invest. Section 1092
defines a "straddle" as offsetting positions with respect to personal property;
for these purposes, options and futures contracts are personal property. Section
1092 generally provides that any loss from the disposition of a position in a
straddle generally may be deducted only to the extent the loss exceeds the
unrealized gain on the offsetting positions(s) of the straddle. Section 1092
also provides certain "wash sale" rules, which apply to transactions where a
position is sold at a loss and a new offsetting position is acquired within a
prescribed period, and "short sale" rules applicable to straddles. If a Fund
makes certain elections, the amount, character and timing of the recognition of
gains and losses from the affected straddle positions would be determined under
rules that vary according to the elections made. Because only a few of the
regulations implementing the straddle rules have been promulgated, the tax
consequences to a Fund of straddle transactions are not entirely clear.

         If a Fund has an "appreciated financial position" -- generally, an
interest (including an interest through an option, futures or forward contract
or short sale) with respect to any stock, debt instrument (other than "straight
debt") or partnership interest the fair market value of which exceeds its
adjusted basis -- and enters
    

                                       29

<PAGE>



   
into a "constructive sale" of the same or substantially similar property, the
Fund will be treated as having made an actual sale thereof, with the result that
gain will be recognized at that time. A constructive sale generally consists of
a short sale, an offsetting notional principal contract or futures or forward
contract entered into by a Fund or a related person with respect to the same or
substantially similar property. In addition, if the appreciated financial
position is itself a short sale or such a contract, acquisition of the
underlying property or substantially similar property will be deemed a
constructive sale.

         ZERO COUPON AND PAY-IN-KIND BONDS Each Fund may acquire zero coupon
bonds or other debt securities issued with original issue discount. As a holder
of those securities, a Fund must include in its income the original issue
discount that accrues on the securities during the taxable year, even if it
receives no corresponding payment on the securities during the year. Similarly,
High Yield must include in its gross income securities it receives as "interest"
on pay-in-kind securities. Because each Fund annually must distribute
substantially all of its investment company taxable income, including any earned
original issue discount and other non-cash income, to satisfy the Distribution
Requirement and avoid imposition of the Excise Tax, it may be required in a
particular year to distribute as a dividend an amount that is greater than the
total amount of cash it actually receives. Those distributions will be made from
a Fund's cash assets or from the proceeds of sales of portfolio securities, if
necessary. A Fund may realize capital gains or losses from those sales, which
would increase or decrease its investment company taxable income and/or net
capital gain.
    

The following additional tax information applies only to High Yield:

   
    

   
         PASSIVE FOREIGN INVESTMENT COMPANIES The Fund may invest in the stock
of "passive foreign investment companies" ("PFICs"). A PFIC is a foreign
corporation -- other than a "controlled foreign corporation" (i.e., a foreign
corporation in which, on any day during its taxable year, more than 50% of the
total voting power of all voting stock therein or the total value of all stock
therein is owned, directly, indirectly, or constructively, by "U.S.
shareholders," defined as U.S. persons that individually own, directly,
indirectly, or constructively, at least 10% of that voting power) as to which
the Fund is a U.S. shareholder -- that, in general, meets either of the
following tests: (1) at least 75% of its gross income is passive or (2) an
average of at least 50% of its assets produce, or are held for the production
of, passive income. Under certain circumstances, the Fund will be subject to
federal income tax on a portion of any "excess distribution" received on the
stock of a PFIC or of any gain on disposition of that stock (collectively "PFIC
income"), plus interest thereon, even if the Fund distributes the PFIC income as
a taxable dividend to its shareholders. The balance of the PFIC income will be
included in the Fund's investment company taxable income and, accordingly, will
not be taxable to it to the extent that income is distributed to its
shareholders.

         If the Fund invests in a PFIC and elects to treat the PFIC as a
"qualified electing fund" ("QEF"), then in lieu of the foregoing tax and
interest obligation, the Fund would be required to include in income each year
its pro rata share of the QEF's annual ordinary earnings and net capital gain --
which probably would have to be distributed by the Fund to satisfy the
Distribution Requirement and avoid imposition of the Excise Tax --
    

                                       30

<PAGE>



   
even if those earnings and gain were not distributed to the Fund by the QEF. In
most instances it will be very difficult, if not impossible, to make this
election because of certain requirements thereof.

         The Fund may elect to "mark to market" its stock in any PFIC.
"Marking-to-market," in this context, means including in ordinary income each
taxable year the excess, if any, of the fair market value of the stock over the
Fund's adjusted basis therein as of the end of that year. Pursuant to the
election, the Fund also will be allowed to deduct (as an ordinary, not capital,
loss) the excess, if any, of its adjusted basis in PFIC stock over the fair
market value thereof as of the taxable year-end, but only to the extent of any
net mark-to-market gains with respect to that stock included in income by the
Fund for prior taxable years. The Fund's adjusted basis in each PFIC's stock
subject to the election will be adjusted to reflect the amounts of income
included and deductions taken thereunder. Regulations proposed in 1992 would
provide a similar election with respect to the stock of certain PFICs.
    

   
    

   
         FOREIGN CURRENCIES Gains or losses (1) from the disposition of foreign
currencies, (2) from the disposition of a debt security denominated in a foreign
currency that are attributable to fluctuations in the value of the foreign
currency between the dates of acquisition and disposition of the security
attributable to fluctuations in exchange rates that occur between the time the
Fund accrues dividends, interest or other receivables or accrues expenses or
other liabilities denominated in a foreign currency and the time the Fund
actually collects the receivables or pays the liabilities generally will be
treated as ordinary income or ordinary loss , and (3) that are referred to under
the Code as "section 988" gains or losses, may increase or decrease the amount
of the Fund's investment company taxable income to be distributed to its
shareholders.

         MISCELLANEOUS If the Fund invests in shares of common stock or
preferred stock or otherwise holds dividend-paying securities as a result of
exercising a conversion privilege, a portion of the dividends from its
investment company taxable income (whether paid in cash or reinvested in
additional Fund shares) may be eligible for the dividends-received deduction
allowed to corporations. The eligible portion may not exceed the aggregate
dividends received by the Fund from U.S. corporations. However, dividends
received by a corporate shareholder and deducted by it pursuant to the
dividends-received deduction are subject indirectly to the federal alternative
minimum tax.
    

                 ADDITIONAL PURCHASE AND REDEMPTION INFORMATION

FUTURE FIRST SYSTEMATIC INVESTMENT PLAN AND TRANSFER OF FUNDS FROM FINANCIAL
- ----------------------------------------------------------------------------
INSTITUTIONS
- ------------

   
         The Primary Shares Prospectus explains that you may buy additional
Primary Shares through the Future First Systematic Investment Plan. Under this
plan you may arrange for automatic monthly investments in Primary Shares of $50
or more by authorizing Boston Financial Data Services ("BFDS"), the Funds'
transfer agent, to transfer funds to be used to buy Primary Shares at the per
share net asset value determined on the day the funds are sent to your bank. You
will receive a quarterly account statement. You may terminate the Future First
Systematic Investment Plan at any time without charge or penalty. Forms to
enroll in the Future First Systematic Investment Plan are available from any
Legg Mason or affiliated office.
    

         Investors in Primary Shares may also buy additional Primary Shares
through a plan permitting transfers of funds from a financial institution.
Certain financial institutions may allow the investor, on a pre-authorized
basis, to have $50 or more automatically transferred monthly for investment in
shares of a Fund to:

                      Legg Mason Wood Walker, Incorporated
                                Funds Processing
                                 P.O. Box 1476
                         Baltimore, Maryland 21203-1476

         If the investor's check is not honored by the institution it is drawn
on, the investor may be subject to extra charges in order to cover collection
costs. These charges may be deducted from the investor's shareholder account.

SYSTEMATIC WITHDRAWAL PLAN
- --------------------------
   
         If you own Primary Shares with a net asset value of $5,000 or more, you
may also elect to make systematic withdrawals from your Fund account of a
minimum of $50 on a monthly basis. The amounts paid to you each month are
obtained by redeeming sufficient Primary Shares from your account to provide the
withdrawal amount that you have specified. The Systematic Withdrawal Plan is not
currently available for shares held in a Retirement Plan (collectively referred
to as "Retirement Plans"). You may change the monthly amount to be paid to you
without charge not more than once a year by notifying your Financial Advisor or
Service Provider. Redemptions will be made at the Primary Shares' net asset
value per share determined as of the close of regular trading on the New York
Stock Exchange ("Exchange") on the first day of each month. If the Exchange is
not open for business on that day, the shares will be redeemed at the Primary
Shares' per share net asset value determined as of the close of regular trading
on the Exchange on the preceding business day. The check for the withdrawal
payment will usually be mailed to you on the next business day following
redemption. If you elect to participate in the Systematic Withdrawal Plan,
dividends and other distributions on all Primary Shares in your account must be
automatically reinvested in Primary Shares. You may terminate the Systematic
Withdrawal Plan at any time without charge or penalty. Each Fund, its transfer
agent, and Legg Mason also reserve the right to modify or terminate the
Systematic Withdrawal Plan at any time.
    

         Withdrawal payments are treated as a sale of shares rather than as a
dividend or other distribution. These payments are taxable to the extent that
the total amount of the payments exceeds the tax basis of the shares sold. If
the periodic withdrawals exceed reinvested dividends and other distributions,
the amount of your original investment may be correspondingly reduced.


                                       32

<PAGE>



         Ordinarily, you should not purchase additional shares of the Fund in
which you have an account if you maintain a Systematic Withdrawal Plan because
you may incur tax liabilities in connection with such purchases and withdrawals.
Each Fund will not knowingly accept purchase orders from you for additional
shares if you maintain a Systematic Withdrawal Plan unless your purchase is
equal to at least one year's scheduled withdrawals. In addition, if you maintain
a Systematic Withdrawal Plan you may not make periodic investments under the
Future First Systematic Investment Plan.

The following information applies only to Government Money Market:

CONVERSION TO FEDERAL FUNDS
- ---------------------------

         A cash deposit made after the daily cashiering deadline of the Legg
Mason office in which the deposit is made will be credited to your Legg Mason
brokerage account ("Brokerage Account") on the next business day following the
day of deposit, and the resulting free credit balance will be invested on the
second business day following the day of receipt.

LEGG MASON PREMIER ASSET MANAGEMENT ACCOUNT/VISA ACCOUNT
- --------------------------------------------------------

         Shareholders of the Fund who have cash or negotiable securities
(including Government Money Market shares) valued at $20,000 or more in accounts
with Legg Mason may subscribe to Legg Mason's Premier Asset Management Account
("Premier"). This program provides a direct link between a shareholder's
Government Money Market account and his or her Brokerage Account. Premier
provides shareholders with a convenient method to invest in the Fund through
their Brokerage Account, which includes automatic daily investment of free
credit balances of $100 or more and automatic weekly investment of free credit
balances of less than $100 into your designated money market fund.

         Premier is a comprehensive financial service which combines a
shareholder's Fund account, a preferred customer VISA Gold debit card, a Legg
Mason Brokerage Account and unlimited checkwriting with no minimum check amount.
Premier is offered as an exclusive preferred customer service for shareholders
of certain Legg Mason funds.

         The VISA Gold debit card may be used to purchase merchandise or
services from merchants honoring VISA or to obtain cash advances (which a bank
may limit to $5,000 or less, per account per day) from any bank honoring VISA.

         Checks, VISA charges and cash advances are posted to the shareholder's
margin account and create automatic same day redemptions if shares are available
in the Fund. If Fund shares have been exhausted, the debits will remain in the
margin account, reducing the cash available. The shareholder will receive one
consolidated monthly statement which details all Fund transactions, securities
activity, check writing activity and VISA Gold purchases and cash advances.

         BancOne Columbus ("BancOne"), 757 Carolyn Avenue, Columbus, Ohio 43271,
is the Fund's agent for processing payment of VISA Gold debit card charges and
clearance of checks written on the Premier Account. Shareholders are subject to
BancOne's rules and regulations governing VISA accounts, including the right of
BancOne not to honor VISA drafts in amounts exceeding the authorization limit of
the shareholder's account at the time the VISA draft is presented for payment.
The authorization limit is determined daily by taking the shareholder's Fund
account balance and subtracting (1) all shares purchased by other than federal
funds wired within 15 days; (2) all shares for which certificates have been
issued; and (3) any previously authorized VISA transaction.

PREFERRED CUSTOMER CARD SERVICES
- --------------------------------

                                       33

<PAGE>



         Unlike some other investment programs which offer the VISA card
privilege, Premier also includes travel/accident insurance at no added cost when
shareholders purchase travel tickets with their Premier VISA Gold debit card.
Coverage is provided through VISA and extends up to $250,000.

         If a VISA Gold debit card is lost or stolen, the shareholder should
report the loss immediately by contacting Legg Mason directly between the hours
of 8:30 a.m. and 5:00 p.m., or BancOne collect after hours at 1-614-248-4242.
Those shareholders who subscribe to the Premier VISA account privilege may be
liable for the unauthorized use of their VISA Gold debit card in amounts up to
$50.

         Legg Mason is responsible for all Premier VISA Gold debit card
inquiries as well as billing and account resolutions. Simply call Legg Mason
Premier Client Services directly between 8:30 a.m. and 5:00 p.m., Eastern time,
at 1-800-253-0454 or 1-410-528-2066 with your account inquiries.

AUTOMATIC PURCHASES OF FUND SHARES
- ----------------------------------

         For shareholders participating in the Premier program who sell shares
held in their Brokerage Account, any free credit balances of $100 or more
resulting from any such sale will automatically be invested in shares of the
Fund on the same business day the proceeds of sale are credited to the Brokerage
Account. Free credit balances of less than $100 will be invested in Fund shares
weekly.

         Free credit balances arising from sales of Brokerage Account shares for
cash (i.e., same day settlement), redemption of debt securities, dividend and
interest payments and cash deposits of $100 or more will be invested
automatically in Fund shares on the next business day following the day the
transaction is credited to the Brokerage Account.

         Fund shares will receive the next dividend declared following purchase
(normally 12:00 noon, Eastern time, on the following business day). A purchase
order will not become effective until cash in the form of federal funds is
received by the Fund.

HOW TO OPEN A PREMIER ACCOUNT
- -----------------------------

         To subscribe to Premier services, clients must contact Legg Mason to
execute both a Premier Agreement with Legg Mason and a VISA Account Application
with BancOne. Legg Mason charges a fee for the Premier service, which is
currently $85 per year for individuals and $100 per year for businesses and
corporations. Legg Mason reserves the right to alter or waive the conditions
upon which a Premier Account may be opened. Both Legg Mason and BancOne reserve
the right to terminate or modify any shareholder's Premier services at their
discretion.

   
         You may request Premier Account Status by filling out the Premier Asset
Management Account Agreement and Check Application which can be obtained from
your Financial Advisor or Service Provider. You will receive your VISA Gold
debit card (if applicable) from BancOne. The Premier VISA Gold debit card may be
used at over 8 million locations, including 23,000 ATMs, in 24 countries around
the world. Premier checks will be sent to you directly. There is no limit to the
number of checks you may write against your Premier account.

         Shareholders should be aware that the various features of the Premier
program are intended to provide easy access to assets in their accounts and that
the Premier Account is not a bank account. Additional information about the
Premier program is available by calling your Financial Advisor or Service
Provider or Legg Mason's Premier Client Services.
    

OTHER INFORMATION REGARDING REDEMPTION
- --------------------------------------


                                       34

<PAGE>



         Government Money Market reserves the right to modify or terminate the
check, wire, telephone or VISA Gold card redemption services described in the
Prospectus and this Statement of Additional Information at any time.

         You may request Government Money Market's checkwriting service by
sending a written request to Legg Mason. State Street will supply you with
checks which can be drawn on an account of Government Money Market maintained
with State Street. When honoring a check presented for payment, the Fund will
cause State Street to redeem exactly enough full and fractional shares from your
account to cover the amount of the check. Canceled checks will be returned to
you.

         Check redemption is subject to State Street's rules and regulations
governing checking accounts. Checks should not be used to close a Government
Money Market account because when the check is written you will not know the
exact value of the account, including accrued dividends, on the day the check
clears. Persons obtaining certificates for their shares may not use the
checkwriting service.

For all of the Funds:

         The date of payment for a redemption may not be postponed for more than
seven days, and the right of redemption may not be suspended, except (i) for any
period during which the Exchange is closed (other than for customary weekend and
holiday closings), (ii) when trading in markets a Fund normally utilizes is
restricted, or an emergency, as defined by rules and regulations of the SEC,
exists, making disposal of that Fund's investments or determination of its net
asset value not reasonably practicable, or (iii) for such other periods as the
SEC by regulation or order may permit for protection of a Fund's shareholders.
In the case of any such suspension, you may either withdraw your request for
redemption or receive payment based upon the net asset value next determined
after the suspension is lifted.

         Each Fund reserves the right, under certain conditions, to honor any
request or combination of requests for redemption from the same shareholder in
any 90-day period, totaling $250,000 or 1% of the net assets of the Fund,
whichever is less, by making payment in whole or in part by securities valued in
the same way as they would be valued for purposes of computing that Fund's net
asset value per share. If payment is made in securities, a shareholder should
expect to incur brokerage expenses in converting those securities into cash and
will be subject to fluctuation in the market price of those securities until
they are sold. Each Fund does not redeem "in kind" under normal circumstances,
but would do so where the Adviser determines that it would be in the best
interests of the shareholders as a whole.

                            PERFORMANCE INFORMATION

For Government Intermediate, Investment Grade and High Yield:

         TOTAL RETURN CALCULATIONS Average annual total return quotes used in a
Fund's advertising and other promotional materials ("performance
advertisements") are calculated separately for each Class according to the
following formula:

                   n
             P(1+T)  = ERV
where        P                 =       a hypothetical initial payment of $1,000
             T                 =       average annual total return
             n                 =       number of years
             ERV               =       ending redeemable value of a
                                       hypothetical $1,000 payment made at the
                                       beginning of that period.

         Under the foregoing formula, the time periods used in performance
advertisements will be based on rolling calendar quarters, updated at least to
the last day of the most recent quarter prior to submission of the performance
advertisements for publication. Total return, or "T" in the formula above, is
computed by finding

                                       35

<PAGE>



the average annual change in the value of an initial $1,000 investment over the
period. In calculating the redeeming value, all dividends and other
distributions by a Fund are assumed to have been reinvested at net asset value
on the reinvestment dates during the period.

         YIELD Yields used in a Fund's performance advertisements for each Class
of Shares are calculated by dividing a Fund's net investment income for a 30-day
period ("Period") attributable to that Class, by the average number of shares in
that Class entitled to receive dividends during the Period, and expressing the
result as an annualized percentage (assuming semi-annual compounding) of the
maximum offering price per share at the end of the Period. Yield quotations are
calculated according to the following formula:

                                          6
         Yield          =     2 [(a-b +1)   - 1]
                                  ------
                                   cd
     where:       a     =     interest earned during the Period
                  b     =     expenses accrued for the Period (net of
                              reimbursements)
                  c     =     the average daily number of shares outstanding
                              during the Period that were
                              entitled to receive dividends
                  d     =     the maximum offering price per share on the last
                              day of the Period.

         Except as noted below, in determining interest earned during the Period
(variable "a" in the above formula), a Fund calculates interest earned on each
debt obligation held by it during the Period by (1) computing the obligation's
yield to maturity based on the market value of the obligation (including actual
accrued interest) on the last business day of the Period or, if the obligation
was purchased during the Period, the purchase price plus accrued interest and
(2) dividing the yield to maturity by 360, and multiplying the resulting
quotient by the market value of the obligation (including actual accrued
interest). Once interest earned is calculated in this fashion for each debt
obligation held by the Fund, interest earned during the Period is then
determined by totalling the interest earned on all debt obligations. For the
purposes of these calculations, the maturity of an obligation with one or more
call provisions is assumed to be the next call date on which the obligation
reasonably can be expected to be called or, if none, the maturity date.

         With respect to the treatment of discount and premium on
mortgage-backed and other asset-backed obligations that are expected to be
subject to monthly payments of principal and interest ("paydowns"): (1) a Fund
accounts for gain or loss attributable to actual paydowns as an increase or
decrease to interest income during the period and (2) a Fund accrues the
discount and amortizes the premium on the remaining obligation, based on the
cost of the obligation, to the weighted average maturity date or, if weighted
average maturity information is not available, to the remaining term of the
obligation.

   
         The yield for Primary Shares of Government Intermediate, Investment
Grade and High Yield for the 30-day period ended December 31, 1997 was 5.35%,
5.69% and 7.37%, respectively. The 30-day yield for Navigator Shares of
Government Intermediate and Investment Grade for the same period was 5.91% and
6.28%, respectively. As of the date of this Statement of Additional Information,
Navigator Shares of High Yield have no performance record. Yields of Government
Intermediate and Investment Grade would have been lower if the Manager had not
waived a portion of those Funds' expenses.
    

For Government Money Market:

         YIELD The current annualized yield for the Fund is based upon a
seven-day period and is computed by determining the net change in the value of a
hypothetical account in the Fund. The net change in the value of the account
includes the value of dividends and of additional shares purchased with
dividends, but does not include realized gains and losses or unrealized
appreciation and depreciation. In addition, the Fund may use a compound
effective annualized yield quotation which is calculated as prescribed by SEC
regulations, by adding one to the base period return (calculated as described
above), raising the sum to a power equal to 365 divided by 7, and subtracting
one.


                                       36

<PAGE>



         The Fund's yield may fluctuate daily depending upon such factors as the
average maturity of its securities, changes in investments, changes in interest
rates and variations in operating expenses. Therefore, current yield does not
provide a basis for determining future yields. The fact that the Fund's current
yield will fluctuate and that shareholders' principal is not guaranteed or
insured should be considered in comparing the Fund's yield with yields on
fixed-income investments, such as insured savings certificates. In comparing the
yield of the Fund to other investment vehicles, consideration should be given to
the investment policies of each, including the types of investments owned,
lengths of maturities of the portfolio, the method used to compute the yield and
whether there are any special charges that may reduce the yield.

OTHER INFORMATION
- -----------------

         In performance advertisements each Fund may compare the total return of
a class of shares with data published by Lipper Analytical Services, Inc.
("Lipper"), CDA Investment Technologies, Inc. ("CDA"), Wiesenberger Investment
Companies Service ("Wiesenberger"), or Morningstar Mutual Funds ("Morningstar"),
or with the performance of U.S. Treasury securities of various maturities,
recognized stock, bond and other indexes, including (but not limited to) the
Salomon Brothers Bond Index, Shearson Lehman Bond Index, Shearson Lehman
Government/Corporate Bond Index, the Standard & Poor's 500 Composite Stock Price
Index ("S&P 500"), the Dow Jones Industrial Average ("Dow Jones"), and changes
in the Consumer Price Index as published by the U.S. Department of Commerce.
Each Fund also may refer in such materials to mutual fund performance rankings
and other data, such as comparative asset, expense and fee levels, published by
Lipper, CDA, Wiesenberger or Morningstar. Performance advertisements also may
refer to discussions of a Class of a Fund and comparative mutual fund data and
ratings reported in independent periodicals, including THE WALL STREET JOURNAL,
MONEY Magazine, FORBES, BUSINESS WEEK, FINANCIAL WORLD, BARRON'S, FORTUNE and
THE NEW YORK TIMES.

         Each Fund invests primarily in the fixed-income securities described in
its Prospectus, and does not invest in the equity securities that make up the
S&P 500 or the Dow Jones indices. Comparison with such indices is intended to
show how an investment in a class of shares behaved as compared to indices that
are often taken as a measure of performance of the equity market as a whole. The
indices, like the total return of a class of shares, assume reinvestment of all
dividends and other distributions. They do not take account of the costs or the
tax consequences of investing.

         Each Fund may include discussions or illustrations of the effects of
compounding in performance advertisements. "Compounding" refers to the fact
that, if dividends or other distributions on an investment in a Fund are
reinvested in additional shares, any future income or capital appreciation of
the Fund would increase the value, not only of the original Fund investment, but
also of the additional shares received through reinvestment. As a result, the
value of the Fund investment would increase more quickly than if dividends or
other distributions had been paid in cash.

         Each Fund may also compare the performance of a Class of shares with
the performance of bank certificates of deposit (CDS) as measured by the CDA
Investment Technologies, Inc. Certificate of Deposit Index and the Bank Rate
Monitor National Index. In comparing the performance of a Class to CD
performance, investors should keep in mind that bank CDS are insured in whole or
in part by an agency of the U.S. Government and offer fixed principal and fixed
or variable rates of interest, and that bank CD yields may vary. Fund shares are
not insured or guaranteed by the U.S. Government and returns and net asset value
will fluctuate. The securities held by a Fund generally have longer maturities
than most CDS and may reflect interest rate fluctuations for longer-term
securities.

         Fund advertisements may reference the history of the distributor and
its affiliates, and the education and experience of the portfolio manager.
Advertisements may also describe techniques the Adviser employs in selecting
among the sectors of the fixed-income market and may focus on the technique of
"value investing." With value investing, the Adviser invests in those securities
it believes to be undervalued in relation to the long-term earning power or
asset value of their issuers. Securities may be undervalued because of

                                       37

many factors, including market decline, poor economic conditions, tax-loss
selling or actual or anticipated unfavorable developments affecting the issuer
of the security.

         In advertising, each Fund may illustrate hypothetical investment plans
designed to help investors meet long-term financial goals, such as saving for a
child's college education or for retirement. Sources such as the Internal
Revenue Service, the Social Security Administration, the Consumer Price Index
and Chase Global Data and Research may supply data concerning interest rates,
college tuitions, the rate of inflation, Social Security benefits, mortality
statistics and other relevant information. Each Fund may use other recognized
sources as they become available.

         Each Fund may use data prepared by Ibbotson Associates of Chicago,
Illinois ("Ibbotson") to compare the returns of various capital markets and to
show the value of a hypothetical investment in a capital market. Ibbotson relies
on different indices to calculate the performance of common stocks, corporate
and government bonds and Treasury bills.

         Each Fund may illustrate and compare the historical volatility of
different portfolio compositions where the performance of stocks is represented
by the performance of an appropriate market index, such as the S&P 500 and the
performance of bonds is represented by a nationally recognized bond index, such
as the Lehman Brothers Long-Term Government Bond Index.

         Each Fund may also include in advertising biographical information on
key investment and managerial personnel.

         Each Fund may advertise examples of the potential benefits of periodic
investment plans, such as dollar cost averaging, a long-term investment
technique designed to lower average cost per share. Under such a plan, an
investor invests in a mutual fund at regular intervals a fixed dollar amount
thereby purchasing more shares when prices are low and fewer shares when prices
are high. Although such a plan does not guarantee profit or guard against loss
in declining markets, the average cost per share could be lower than if a fixed
number of shares were purchased at the same intervals. Investors should consider
their ability to purchase shares through low price levels.
   
         Each Fund may discuss Legg Mason's tradition of service. Since 1899,
Legg Mason and its affiliated companies have helped investors meet their
specific investment goals and have provided a full spectrum of financial
services. Legg Mason affiliates serve as investment advisors for private
accounts and mutual funds with assets of more than $71.0 billion as of March 31,
1998.
    
         In advertising, each Fund may discuss the advantages of saving through
tax-deferred retirement plans or accounts, including the advantages and
disadvantages of "rolling over" a distribution from a retirement plan into an
IRA, factors to consider in determining whether you qualify for such a rollover,
and the other options available. These discussions may include graphs or other
illustrations that compare the growth of a hypothetical tax-deferred investment
to the after-tax growth of a taxable investment.

         The following tables show the value, as of the end of each fiscal year,
of a hypothetical investment of $10,000 ($15,000 for High Yield) made in each
Fund at commencement of operations of each class of Fund shares. The tables
assume that all dividends and other distributions are reinvested in each
respective Fund. They include the effect of all charges and fees applicable to
the respective class of shares the Fund has paid. (There are no fees for
investing or reinvesting in the Funds, and there are no redemption fees.) They
do not include the effect of any income taxes that an investor would have to pay
on distributions.

         The table above for High Yield is based only on Primary Shares. As of
the date of this Statement of Additional Information, Navigator Shares of High
Yield have no performance history of their own.

                            VALUATION OF FUND SHARES

For Government Intermediate, Investment Grade and High Yield:

   
         Net asset value of a Fund share is determined daily for each Class as
of the close of the Exchange, on every day that the Exchange is open, by
subtracting liabilities attributable to that Class, from total assets
attributable to that Class, and dividing the result by the number of shares of
that Class outstanding. Pricing will not be done on days when the Exchange is
closed. The Exchange currently observes the following holidays: New Year's Day,
Martin Luther King, Jr. Day, President's Day, Good Friday, Memorial Day,
Independence Day, Labor Day, Thanksgiving and Christmas. When market quotations
for institutional size positions are readily available portfolio securities are
valued based upon market quotations. Where such market quotations are not
readily available, securities are valued based upon appraisals received from a
pricing service using a computerized matrix system or based upon appraisals
derived from information concerning the security or similar securities received
from recognized dealers in those securities. The methods used by the pricing
service and the quality of the valuations so established are reviewed by the
Adviser under the general supervision of the Corporation's Board of Directors.
The amortized cost method of valuation is used with respect to obligations with
60 days or less remaining to maturity unless the Adviser determines that this
does not represent fair value. All other assets are valued at fair value as
determined in good faith, by or under the direction of the Corporation's Board
of Directors. Premiums received on the sale of put and call options are included
in net asset value of each class, and the current market value of options sold
by the Fund will be subtracted from net assets of each class.
    

For Government Money Market:

         Government Money Market attempts to stabilize the value of a share at
$1.00. Net asset value will not be calculated on days when the Exchange is
closed.

         USE OF THE AMORTIZED COST METHOD The directors have determined that the
interests of shareholders are best served by using the amortized cost method for
determining the value of portfolio instruments. Under this method, portfolio
instruments are valued at the acquisition cost, as adjusted for amortization of
premium or accumulation of discount, rather than at current market value. The
Board of Directors continually assesses the appropriateness of this method of
valuation.


                                       41

<PAGE>



     The Fund's use of the amortized cost method of valuing portfolio
instruments depends on its compliance with Rule 2a-7 under the 1940 Act. Under
that Rule, the directors must establish procedures reasonably designed to
stabilize the net asset value per share, as computed for purposes of
distribution and redemption, at $1.00 per share, taking into account current
market conditions and the Fund's investment objective.

         MONITORING PROCEDURES The Fund's procedures include monitoring the
relationship between the amortized cost value per share and the net asset value
per share based upon available indications of market value. If there is a
difference of more than 0.5% between the two, the directors will take any steps
they consider appropriate (such as shortening the dollar-weighted average
portfolio maturity) to minimize any material dilution or other unfair results
arising from differences between the two methods of determining net asset value.

         INVESTMENT RESTRICTIONS Rule 2a-7 requires the Fund to limit its
investments to instruments that, (i)in the opinion of the Adviser, present
minimal credit risk and (ii) (a) are rated in one of the two highest rating
categories by at least two NRSROs (or one, if only one NRSRO has rated the
security) or, (b) if unrated, are determined to be of comparable quality by the
Adviser, all pursuant to procedures determined by the Board of Directors
("Eligible Securities"). The Fund may invest no more than 5% of its total assets
in securities that are Eligible Securities but have not been rated in the
highest short-term ratings category by at least two NRSROs (or by one NRSRO, if
only one NRSRO has assigned the obligation a short-term rating) or, if the
obligations are unrated, determined by the Adviser to be of comparable quality
("Second Tier Securities"). In addition, the Fund will not invest more than 1%
of its total assets or $1 million (whichever is greater) in the Second Tier
Securities of a single issuer. The Rule requires the Fund to maintain a
dollar-weighted average portfolio maturity appropriate to the objective of
maintaining a stable net asset value of $1.00 per share and in any event not
more than 90 days. In addition, under the Rule, no instrument with a remaining
maturity (as defined in the Rule) of more than 397 days can be purchased by the
Fund; except that the Fund may hold securities with remaining maturities greater
than 397 days as collateral for repurchase agreements and other collateralized
transactions of short duration.

         Should the disposition of a portfolio security result in a
dollar-weighted average portfolio maturity of more than 90 days, the Fund will
invest its available cash to reduce the average maturity to 90 days or less as
soon as possible.

         It is the Fund's usual practice to hold portfolio securities to
maturity and realize par, unless the Adviser determines that sale or other
disposition is appropriate in light of the Fund's investment objective. Under
the amortized cost method of valuation, neither the amount of daily income nor
the net asset value is affected by any unrealized appreciation or depreciation
of the portfolio.

         In periods of declining interest rates, the indicated daily yield on
shares of the Fund, computed by dividing the annualized daily income on the
Fund's investment portfolio by the net asset value computed as above, may tend
to be higher than a similar computation made by using a method of valuation
based upon market prices and estimates.

         In periods of rising interest rates, the indicated daily yield on
shares of the Fund computed the same way may tend to be lower than a similar
computation made by using a method of calculation based upon market prices and
estimates.

                          TAX-DEFERRED RETIREMENT PLANS

   
         Investors may invest in Primary Shares of a Fund through Retirement
Plans. In general, income earned through the investment of assets of qualified
Retirement Plans is not taxed to the beneficiaries thereof until the income is
distributed to them. Investors who are considering establishing such a plan
should consult their attorneys or other tax advisers with respect to individual
tax questions. The option of investing in these plans through regular payroll
deductions may be arranged with your Financial Advisor or Service Provider and
your
    

                                       42

employer. Additional information with respect to these plans is available upon
request from your Financial Advisor or Service Provider
    

   
    

   
         TRADITIONAL IRA. Certain Primary Share investors may obtain tax
advantages by establishing an IRA. Specifically, except as noted below, if
neither you nor your spouse is an active participant in a qualified employer or
government retirement plan, or if either you or your spouse is an active
participant and your adjusted gross income does not exceed a certain level, each
of you may deduct cash contributions made to an IRA in an amount for each
taxable year not exceeding the lesser of 100% of your earned income or $2,000. A
married investor who is not an active participant in such a plan and files a
joint income tax return with his or her spouse (and their combined adjusted
gross income does not exceed $150,000) is not affected by the spouse's active
participant status. In addition, if your spouse is not employed and you file a
joint return, you may establish a separate IRA for your spouse and contribute up
to a total of $4,000 to the two IRAs, provided that neither contribution exceeds
$2,000. If your employer's plan qualifies as a SARSEP, permits voluntary
contributions and meets certain requirements, you may make voluntary
contributions to that plan that are treated as deductible IRA contributions.
    

         Even if you are not in one of the categories described in the preceding
paragraph, you may find it advantageous to invest in Primary Shares through
nondeductible IRA contributions, up to certain limits, because all dividends and
other distributions on your Primary Shares are then not immediately taxable to
you or the IRA; they become taxable only when distributed to you. To avoid
penalties, your interest in an IRA must be distributed, or start to be
distributed, to you not later than the end of the taxable year in which you
attain age 70 1/2. Distributions made before age 59 1/2, in addition to being
taxable, generally are subject to a penalty equal to 10% of the distribution,
except in the case of death or disability or where the distribution is rolled
over into another qualified plan or certain other situations.

   
         ROTH IRA. A shareholder whose adjusted gross income (or combined
adjusted gross income with his or her spouse) does not exceed certain levels may
establish and contribute up to $2,000 per tax year to a Roth IRA. In addition,
for a shareholder whose adjusted gross income does not $100,000 (or is not
married filing a separate return), certain distributions from traditional IRAs
may be rolled over to a Roth IRA and any of the shareholder's traditional IRAs
may be converted to a Roth IRA; these rollover distributions and conversions
are, however, subject to federal income tax.

         Contributions to a Roth IRA are not deductible; however, earnings
accumulate tax-free in a Roth IRA, and withdrawals of earnings are not subject
to federal income tax if the account has been held for at least five years (or
in the case of earnings attributable to rollover contributions from or
conversions of a traditional IRA, the rollover or conversion occurred more than
five years before the withdrawal) and the account holder has reached age 59 1/2
(or certain other conditions apply).

         EDUCATION IRA. Although not technically for retirement savings,
Education IRAs provide a vehicle for saving for a child's higher education. An
Education IRA may be established for the benefit of any minor and any person
whose adjusted gross income does not exceed certain levels may contribute to an
Education IRA, provided that no more than $500 may be contributed for any year
to Education IRAs for the same beneficiary. Contributions are not deductible and
may not be made after the beneficiary reaches age 18; however, earnings
accumulate tax-free, and withdrawals are not subject to tax if used to pay the
qualified higher education expenses of the beneficiary (or transferred to an
Education IRA of a qualified family member).

Simplified Employee Pension Plan -- SEP
- ---------------------------------------

         Legg Mason makes available to corporate and other employers a SEP for
investment in Primary Shares.

Savings Incentive Match Plan for Employees - SIMPLE
- ---------------------------------------------------

   
           An employer with no more than 100 employees that does not maintain
another retirement plan instead may establish a SIMPLE either as separate IRAs
or as part of a Code section 401(k) plan. A SIMPLE, which is not subject to the
complicated nondiscrimination rules that generally apply to qualified retirement
plans, will allow certain employees to make elective contributions of up to
$6,000 per year and will require the employer to make either matching
contributions up to 3% of each such employee's salary or a 2% nonelective
contribution.
    

         Withholding at the rate of 20% is required for federal income tax
purposes on certain distributions (excluding, for example, certain periodic
payments) from the foregoing retirement plans (except IRAs and SEPs), unless the
recipient transfers the distribution directly to an "eligible retirement plan"
(including IRAs and other qualified plans) that accepts those distributions.
Other distributions generally are subject to regular wage withholding at the
rate of 10% (depending on the type and amount of the distribution), unless the
recipient elects not to have any withholding apply. Primary Share investors
should consult their plan administrator or tax adviser for further information.

                              MANAGEMENT AGREEMENT

         Legg Mason Fund Adviser, Inc. ("Manager"), 100 Light Street, Baltimore,
MD 21202, is a wholly owned subsidiary of Legg Mason, Inc., which is also the
parent of Legg Mason Wood Walker, Incorporated. The Manager serves as the
manager for each Fund under separate management agreements dated June 19, 1987
for Government Intermediate and Investment Grade, November 1, 1988 for
Government Money Market and January 24, 1994 for High Yield (each a "Management
Agreement"). Each Management Agreement provides that, subject to overall
direction by the Board of Directors, the Manager will manage the investment and
other affairs of each Fund. Under the Management Agreement, the Manager is
responsible for managing each Fund's portfolio of securities and for making
purchases and sales of securities consistent with the investment objectives and
policies described in each Fund's Prospectuses and this Statement of Additional
Information. The Manager is obligated to furnish each Fund with office space and
certain administrative services as well as executive and other personnel
necessary for the operation of the Funds. The Manager and its affiliates also
are responsible for the compensation of directors and officers of the
Corporation who are employees of the Manager and/or its affiliates. The Manager
has delegated the portfolio management functions for each Fund to the Adviser,
Western Asset Management Company.

         As explained in the Funds' Prospectuses, the Manager receives for its
services a management fee, calculated daily and payable monthly, at annual rates
of each Fund's average daily net assets according to the following:

                                                         MANAGEMENT FEE:

         The Manager has agreed to waive its fees and reimburse Government
Intermediate and Investment Grade if and to the extent either Fund's expenses
(exclusive of taxes, interest, brokerage and extraordinary expenses) exceed
during any month annual rates of the Fund's average daily net assets for such
month, or certain asset levels are achieved, whichever occurs first, in
accordance with the following schedule:

         For the years ended December 31, 1997, 1996 and 1995, the Manager
received management fees of $609,203, $519,989 and $453,028, respectively (prior
to fees waived of $395,225, $400,971 and $374,130, respectively), for Investment
Grade.

         For the years ended December 31, 1997, 1996 and 1995, High Yield paid
management fees of $1,987,385, $1,093,156 and $488,993, respectively, to the
Manager.

         During the fiscal years ended December 31, 1997, 1996 and 1995,
Government Money Market paid management fees of $1,670,048, $1,658,682 and
$1,353,415 respectively, to the Manager.
    

         Under each Management Agreement, the Manager will not be liable for any
error of judgment or mistake of law or for any loss suffered by a Fund in
connection with the performance of the respective Management Agreement, except a
loss resulting from a breach of fiduciary duty with respect to the receipt of
compensation for services or losses resulting from willful misfeasance, bad
faith or gross negligence in the performance of its duties or from reckless
disregard of its obligations or duties thereunder.

         Each Management Agreement terminates automatically upon assignment and
is terminable at any time without penalty by vote of the Corporation's Board of
Directors, by vote of a majority of the outstanding voting securities of that
Fund or by the Manager, on not less than 60 days' written notice to the other
party, and may be terminated immediately upon the mutual written consent of the
Manager and the respective Fund.

         Each Fund pays all of its expenses which are not expressly assumed by
the Manager. These expenses include, among others, interest expense, taxes,
brokerage fees and commissions, expenses of preparing and printing prospectuses,
statements of additional information, proxy statements and reports and of
distributing them to existing shareholders, custodian charges, transfer agency
fees, organizational expenses, distribution fees to the Funds' distributor,
compensation of the independent directors, legal, accounting and audit expenses,
insurance expenses, expenses of registering and qualifying shares of each Fund
for sale under federal and state law, governmental fees and expenses incurred in
connection with membership in investment company organizations. Each Fund also
is liable for such nonrecurring expenses as may arise, including litigation to
which a Fund may be a party. Each Fund may also have an obligation to indemnify
the directors and officers of the Corporation with respect to any such
litigation.

         Under each Management Agreement, each Fund has the non-exclusive right
to use the name "Legg Mason" until that Agreement is terminated, or until the
right is withdrawn in writing by the Manager.

                          INVESTMENT ADVISORY AGREEMENT

         The Adviser, Western Asset Management Company, 117 East Colorado
Boulevard, Pasadena, CA 91105, an affiliate of Legg Mason, serves as investment
adviser to each Fund under separate Investment Advisory Agreements, dated June
19, 1987 for Government Intermediate and Investment Grade; November 1, 1988 for
Government Money Market and January 24, 1994 for High Yield, between the Adviser
and the Manager (each an "Advisory Agreement").

         Under the Advisory Agreement, the Adviser is responsible, subject to
the general supervision of the Manager and the Corporation's Board of Directors,
for the actual management of each Fund's assets, including the responsibility
for making decisions and placing orders to buy, sell or hold a particular
security. For the Adviser's services to each Fund, the Manager (not the Fund)
pays the Adviser a fee, computed daily and payable monthly, at an annual rate
(of the fee received by the Manager) equal to the following:

FUND                                          ADVISORY FEE:
- ----                                          -------------
Government Intermediate                            .20%*
Investment Grade                                    40%
Government Money Market                             30%
High Yield                                          77%

* Effective October 1, 1994, the Adviser agreed to waive payments by the Manager
with respect to Government Intermediate in excess of 0.20% annually of
Government Intermediate's average daily net assets.
This does not affect the fee paid by the Fund.

For the fiscal years ended December 31, 1997, 1996 and 1995, the Manager paid
the following fees to the Adviser on behalf of the Funds:

   
Fund:                                      1997         1996         1995
- -----                                      ----         ----         ----

Government Intermediate                  $598,643     $462,253     $466,977
Investment Grade                          $85,591      $47,237      $32,296
High Yield                             $1,530,286     $842,642     $376,525
Government Money Market                  $501,014     $497,604     $406,025
    

         Under each Advisory Agreement, the Adviser will not be liable for any
error of judgment or mistake of law or for any loss suffered by the Manager or
by a Fund in connection with the performance of the Advisory Agreement, except a
loss resulting from a breach of fiduciary duty with respect to the receipt of
compensation

                                       49

<PAGE>



for services or a loss resulting from willful misfeasance, bad faith or gross
negligence on its part in the performance of its duties or from reckless
disregard by it of its obligations or duties thereunder.

         Each Advisory Agreement terminates automatically upon assignment and is
terminable at any time without penalty by vote of the Corporation's Board of
Directors, by vote of a majority of each Fund's outstanding voting securities,
by the Manager or by the Adviser, on not less than 60 days' notice to the
respective Fund and/or the other party(ies). The Advisory Agreement terminates
immediately upon any termination of the Management Agreement or upon the mutual
written consent of the Adviser, the Manager and each Fund.

         To mitigate the possibility that a Fund will be affected by personal
trading of employees, the Corporation, the Manager and the Adviser have adopted
policies that restrict securities trading in the personal accounts of portfolio
managers and others who normally come into advance possession of information on
portfolio transactions. These policies comply, in all material respects, with
the recommendations of the Investment Company Institute.

                      PORTFOLIO TRANSACTIONS AND BROKERAGE

         The portfolio turnover rate is computed by dividing the lesser of
purchases or sales of securities for the period by the average value of
portfolio securities for that period. Short-term securities are excluded from
the calculation. For the years ended December 31, each Fund's (other than
Government Money Market) portfolio turnover rates were as follows:

   
Fund:                                      1997               1996
- -----                                      ----               ----
Government Intermediate                    252%               354%
Investment Grade                           259%               383%
High Yield                                 116%                77%
    

         Under each Advisory Agreement, the Adviser is responsible for the
execution of portfolio transactions. Corporate and government debt securities
are generally traded on the over-the-counter market on a "net" basis without a
stated commission, through dealers acting for their own account and not as
brokers. Prices paid to a dealer in debt securities generally include a
"spread," which is the difference between the price at which the dealer is
willing to purchase and sell the specific security at the time, and includes the
dealer's normal profit. Some portfolio transactions may be executed through
brokers acting as agent. In selecting brokers or dealers, the Adviser must seek
the most favorable price (including the applicable dealer spread) and execution
for such transactions, subject to the possible payment as described below of
higher brokerage commissions for agency transactions or spreads to
broker-dealers who provide research and analysis. A Fund may not always pay the
lowest commission or spread available. Rather, in placing orders on behalf of a
Fund, the Adviser also takes into account such factors as size of the order,
difficulty of execution, efficiency of the executing broker's facilities
(including the services described below) and any risk assumed by the executing
broker.

         Consistent with the policy of most favorable price and execution, the
Adviser may give consideration to research, statistical and other services
furnished by brokers or dealers to the Adviser for its use, may place orders
with broker-dealers who provide supplemental investment and market research and
securities and economic analysis, and may, for agency transactions, pay to these
broker-dealers a higher brokerage commission than may be charged by other
broker-dealers. Such research and analysis may be useful to the Adviser in
connection with services to clients other than the Funds. On the other hand,
research and analysis received by the Adviser from broker-dealers executing
orders for clients other than the Funds may be used for the Fund's benefit. The
Adviser's fee is not reduced by reason of its receiving such brokerage and
research services. For the years ended December 31, the following Funds paid
commissions to broker-dealers who acted as agents in executing options and
futures trades.

         No Fund may buy securities from, or sell securities to, Legg Mason or
its affiliated persons as principal. However, the Corporation's Board of
Directors has adopted procedures in conformity with Rule 10f-3 under the 1940
Act whereby a Fund may purchase securities that are offered in underwritings in
which Legg Mason or any of its affiliated persons is a participant.

         Investment decisions for each Fund are made independently from those of
other funds and accounts advised by the Adviser. However, the same security may
be held in the portfolios of more than one fund or account. When two or more
accounts simultaneously engage in the purchase or sale of the same security, the
prices and amounts will be equitably allocated to each account. In some cases,
this procedure may adversely affect the price or quantity of the security
available to a particular account. In other cases, however, an account's ability
to participate in large-volume transactions may produce better executions and
prices.

                             THE FUNDS' DISTRIBUTOR

         Legg Mason acts as distributor of each Fund's shares pursuant to an
Underwriting Agreement with the Corporation. The Underwriting Agreement
obligates Legg Mason to pay certain expenses in connection with the offering of
a Fund's shares, including compensation to its financial advisors. Legg Mason
also pays for the printing and distribution of prospectuses and periodic reports
used in connection with the offering to prospective investors, after the
prospectuses and reports have been prepared, set in type and mailed to
shareholders at each Fund's expense, and for supplementary sales literature and
advertising costs.

         For the year ended December 31, 1997, Legg Mason incurred the following
expenses with respect to Primary Shares of each Fund:


                           Government    Investment                 Government
                          Intermediate      Grade     High Yield   Money Market
                         -------------------------------------------------------
   
Compensation to sales       $858,000      $292,000     $870,000       $55,000
personnel

Printing and mailing of       44,000        83,000       83,000        89,000

prospective shareholders

Other                        619,000       394,000      794,000       953,000
                         -------------------------------------------------------
Total expenses            $1,534,000      $796,000   $1,773,000    $1,124,000
                         =======================================================
    



   
         The foregoing are estimated and do not include all expenses fairly
allocable to Legg Mason's or its affiliates' efforts to distribute Primary
Shares. The figures for "Other" include allocations of overhead amounts using
methods believed by Legg Mason to be reasonable.
    

         Fairfield Group, Inc., a wholly owned subsidiary of Legg Mason, Inc.,
with principal offices at 200 Gibraltar Road, Horsham, Pennsylvania, acts as a
dealer for Navigator Shares pursuant to a Dealer Agreement with Legg Mason.
Neither Legg Mason nor Fairfield receives any compensation from the Funds for
its activities in selling Navigator Shares.

         The Corporation has adopted a Distribution and Shareholder Services
Plan ("Plan") which, among other things, permits it to pay Legg Mason fees for
its services related to sales and distribution of Primary Shares and for the
provision of ongoing services to Primary Class shareholders. Payments are made
only

                                       51

from assets attributable to Primary Shares. The Plan was adopted, as required by
Rule 12b-1 under the 1940 Act, by a vote of the Board of Directors on May 8,
1987 (for Government Intermediate and Investment Grade), October 27, 1988 (for
Government Money Market) and October 22, 1993 (for High Yield), including a
majority of the directors who are not "interested persons" of the Corporation as
that term is defined in the 1940 Act and who have no direct or indirect
financial interest in the operation of the Plan or the Underwriting Agreement
("12b-1 directors"). Continuation of the Plan was most recently approved by the
Board of Directors on November 7, 1997, including a majority of the 12b-1
directors. In approving the continuance of the Plan, in accordance with the
requirements of Rule 12b-1, the directors considered various factors, including
the amount of the distribution fee. The directors determined that there is a
reasonable likelihood that the Plan will continue to benefit each Fund and its
present and future Primary Class shareholders. The directors noted that, to the
extent the Plan results in additional sales of Primary Shares of a Fund, the
Plan may enable the Fund to achieve economies of scale that could reduce
expenses and to minimize the prospects that the Fund will experience net
redemptions and the accompanying disruption of portfolio management. The Plan
was also approved by the vote of a majority of Government Intermediate's and
Investment Grade's outstanding Primary Shares on April 22, 1988.
    

         The Plan continues in effect only so long as it is approved at least
annually by the vote of a majority of the Board of Directors, including a
majority of the 12b-1 directors, cast in person at a meeting called for the
purpose of voting on the Plan. The Plan may be terminated with respect to each
Fund by vote of a majority of the 12b-1 directors, or by vote of a majority of
the outstanding voting Primary Class securities of a Fund. Any change in the
Plan that would materially increase the distribution cost to a Fund requires
Primary Class shareholder approval. Otherwise, the Plan may be amended by the
directors, including a majority of the 12b-1 directors, as previously described.

         Rule 12b-1 requires that any person authorized to direct the
disposition of monies paid or payable by a Fund, pursuant to the Plan or any
related agreement, shall provide to the Corporation's Board of Directors, and
the directors shall review, at least quarterly, a written report of the amounts
so expended and the purposes for which the expenditures were made. Rule 12b-1
also provides that a Fund may rely on that Rule only if, while the Plan is in
effect, the nomination and selection of the Corporation's independent directors
is committed to the discretion of such independent directors.

         As compensation for its services and expenses, Legg Mason receives from
the Corporation annual distribution and service fees each equivalent to 0.25% of
each Fund's average daily net assets (other than Government Money Market which
has a fee of 0.10%) attributable to Primary Shares in accordance with the Plan.
The distribution and service fees are computed daily and paid monthly. For the
fiscal years ended December 31, 1997, 1996 and 1995, each Fund paid distribution
and service fees to Legg Mason, pursuant to the Underwriting Agreement from
assets attributable to Primary Shares as follows:

   
Government Intermediate paid $1,459,883, $1,135,296 and $1,153,298,
respectively, to Legg Mason; Investment Grade paid $506,442, $432,122 and
$377,479, respectively to Legg Mason; and High Yield paid $1,528,758, $840,822
and $376,148, respectively, to Legg Mason.

         Pursuant to the Plan, Government Money Market is authorized to pay Legg
Mason distribution and service fees not to exceed an annual rate of 0.20% of its
average daily net assets. Legg Mason has agreed that it will not request payment
of more than 0.10% annually from the Fund during the first two years following
implementation of the Plan which occurred on January 10, 1997. For the year
ended December 31, 1997, Government Money Market paid $326,047 to Legg Mason.
    

        THE FUNDS' CUSTODIAN AND TRANSFER AND DIVIDEND-DISBURSING AGENT

         State Street Bank and Trust Company, P.O. Box 1713, Boston,
Massachusetts 02105, serves as custodian of each Fund's assets. Boston Financial

BFDS has contracted with Legg Mason for the latter to assist it with certain of
its duties as transfer agent, for which BFDS compensates Legg Mason.
Shareholders who request an historical transcript of their account will be
charged a fee based upon the number of years researched. Each Fund reserves the
right, upon 60 days' written notice, to make other charges to investors to cover
administrative costs.

                                                                     APPENDIX A

         The following are descriptions of hedging instruments which may be used
by Government Intermediate, Investment Grade or High Yield:

         OPTIONS ON SECURITIES AND FOREIGN CURRENCIES--A call option is a
short-term contract pursuant to which the purchaser of the option, in return for
a premium, has the right to buy the security or currency underlying the option
at a specified price at any time during the term of the option. The writer of
the call option, who receives the premium, has the obligation, upon exercise of
the option during the option term, to deliver the underlying security or
currency against payment of the exercise price. A put option is a similar
contract that gives its purchaser, in return for a premium, the right to sell
the underlying security or currency at a specified price during the option term.
The writer of the put option, who receives the premium, has the obligation, upon
exercise of the option during the option term, to buy the underlying security or
currency at the exercise price.

         OPTION ON A SECURITIES INDEX--An option on a securities index is
similar to an option on a security or foreign currency, except that settlement
of an index option is effected with a cash payment based on the value of the
index and does not involve the delivery of the securities included in the index.
Thus, upon settlement of an index option, the purchaser will realize, and the
writer will pay, an amount based on the difference between the exercise price of
the option and the closing price of the index.

         INTEREST RATE AND FOREIGN CURRENCY FUTURES CONTRACTS--Interest rate and
foreign currency futures contracts are bilateral agreements pursuant to which
one party agrees to make, and the other party agrees to accept, delivery of a
specified type of debt security or currency at a specified future time and at a
specified price. Although such futures contracts by their terms call for actual
delivery or acceptance of debt securities or currency, in most cases the
contracts are closed out before the settlement date without the making or taking
of delivery. An index futures contract is similar to any other futures contract
except that settlement of an index futures contract is effected with a cash
payment based on the value of the index and does not involve the delivery of the
securities included in the index.

         OPTIONS ON FUTURES CONTRACTS--Options on futures contracts are similar
to options on securities or currency, except that an option on a futures
contract gives the purchaser the right, in return for the premium, to assume a
position in a futures contract (a long position if the option is a call and a
short position if the option is a put), rather than to purchase or sell a
security or currency, at a specified price at any time during the option term.
Upon exercise of the option, the delivery of the futures position to the holder
of the option will be accompanied by delivery of the accumulated balance that
represents the amount by which the market price of the futures contract exceeds,
in the case of a call, or is less than, in the case of a put, the exercise price
of the option on the future. The writer of an option, upon exercise, will assume
a short position in the case of a call and a long position in the case of a put.
An option on a bond index futures contract is similar to any other option on a
futures contract except that the purchaser has the right, in return for the
premium, to assume a position in a bond index futures contract at a specified
price at any time during the option term.

         FORWARD CURRENCY CONTRACTS--A forward currency contract involves an
obligation to purchase or sell a specific currency at a specified future date,
which may be any fixed number of days from the contract date agreed upon by the
parties, at a price set at the time the contract is entered into.
