     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 Tax-Free Income Fund ("Trust") is an open-end
      management investment company which currently offers three series.

          The LEGG MASON MARYLAND TAX-FREE INCOME TRUST ("Maryland Tax-Free"),
      is a non-diversified, professionally managed portfolio seeking a high
      level of current income exempt from federal and Maryland state and local
      income taxes, consistent with prudent investment risk and preservation of
      capital.

          The LEGG MASON PENNSYLVANIA TAX-FREE INCOME TRUST ("Pennsylvania
      Tax-Free") is a non-diversified, professionally managed portfolio seeking
      a high level of current income exempt from federal income tax and
      Pennsylvania personal income tax, consistent with prudent investment risk
      and preservation of capital.

          The LEGG MASON TAX-FREE INTERMEDIATE-TERM INCOME TRUST ("Tax-Free
      Intermediate") is a non-diversified, professionally managed portfolio
      seeking a high level of current income exempt from federal income tax,
      consistent with prudent investment risk.

          In attempting to achieve Maryland Tax-Free's objective, the investment
      adviser, Legg Mason Capital Management, Inc. ("Adviser"), invests
      primarily in debt instruments issued by or on behalf of the State of
      Maryland, its political subdivisions, municipalities, agencies,
      instrumentalities or public authorities, the interest on which, in the
      opinion of counsel to the issuers of those instruments, is exempt from
      federal and Maryland state and local income taxes ("Maryland municipal
      obligations") and which are investment grade, I.E., securities rated
      within the four highest grades by Moody's Investors Service, Inc.
      ("Moody's"), Standard & Poor's ("S&P") or Fitch Investors Service, Inc.
      ("Fitch") or, if unrated by Moody's, S&P or Fitch ("unrated securities")
      deemed by the Adviser to be of comparable quality. Maryland Tax-Free also
      may engage in hedging transactions.

          In attempting to achieve Pennsylvania Tax-Free's objective, the
      Adviser invests primarily in debt instruments issued by or on behalf of
      the Commonwealth of Pennsylvania, its political subdivisions,
      municipalities, agencies, instrumentalities or public authorities, the
      interest on which, in the opinion of counsel to the issuers of those
      instruments, is exempt from federal income tax and Pennsylvania personal
      income tax ("Pennsylvania municipal obligations") and which are rated
      investment grade by Moody's, S&P or Fitch, or unrated securities deemed by
      the Adviser to be of comparable quality. Pennsylvania Tax-Free's shares
      are exempt from Pennsylvania county personal property tax to the extent
      that it invests in Pennsylvania municipal obligations. Pennsylvania
      Tax-Free also may engage in hedging transactions.

          In attempting to achieve Tax-Free Intermediate's objective, the
      Adviser invests primarily in debt instruments issued by or on behalf of
      states, territories and possessions of the United States, the District of
      Columbia and their respective authorities, agencies, instrumentalities and
      political subdivisions, the interest on which, in the opinion of counsel
      to the issuers of those instruments, is exempt from federal income tax and
      which are rated investment grade by Moody's, S&P or Fitch, or unrated
      securities deemed by the Adviser to be of comparable quality. Tax-Free
      Intermediate also may engage in hedging transactions.

INVESTMENT TECHNIQUES AND RISKS:
          There can be no assurance that Maryland Tax-Free, Pennsylvania
      Tax-Free and Tax-Free Intermediate (each a "Fund") will achieve their
      respective objectives. The value of the debt instruments held by any Fund,
      and thus the net asset value of Fund shares, generally fluctuates
      inversely with movements in interest rates. Debt instruments with longer
      maturities typically fluctuate more than those with shorter maturities
      when interest rates change. Under normal circumstances, Maryland
      Tax-Free's and Pennsylvania Tax-Free's dollar-weighted average maturities
      are expected to be between 12 and 24 years and Tax-Free Intermediate's
      dollar-weighted average maturity is expected to be between 2 and 10 years;
      therefore, the net asset value of the Funds' shares will be more sensitive
      to interest rate movements and will fluctuate
2

<PAGE>

      more than a portfolio of shorter-term securities. Additionally, changes in
      economic conditions in, or governmental policies of, the State of Maryland
      (with respect to Maryland Tax-Free), the Commonwealth of Pennsylvania
      (with respect to Pennsylvania Tax-Free) and the various states and
      municipalities (with respect to Tax-Free Intermediate) could have a
      significant impact on the performance of the Funds. As non-diversified
      series, the Funds may be subject to greater risk with respect to their
      portfolio securities than investment companies that have a broader range
      of investments, because changes in the financial condition or market
      assessment of a single issuer may cause greater fluctuation in a Fund's
      total return and the price of a Fund's shares. Moody's considers those
      securities rated in its fourth highest category (I.E., Baa) to have
      speculative characteristics. A Fund's participation in hedging and option
      strategies also involves certain investment risks and transaction costs.

      ----------
    (A) See "How You Can Invest In The Funds," page 14, for additional
        information concerning volume reductions, sales charge waivers and
        reduced sales charge purchase plans.
    (B) The sales charge on each Fund will be waived for all shares purchased
        through July 31, 1999. After July 31, 1999, any exchanges of shares
        purchased pursuant to the sales charge waiver will be subject to any
        sales charge imposed by the fund into which you are exchanging, since no
        sales charge was paid on the initial purchase.
    (C) After fee waivers. Pursuant to a voluntary expense limitation, the
        Adviser and Legg Mason have agreed to waive management and 12b-1 fees
        such that total operating expenses relating to Primary Shares (exclusive
        of taxes, interest, brokerage fees, and extraordinary expenses) will not
        exceed annual rates of 0.70% of average daily net assets of each Fund
        until July 31, 1999 or until Maryland Tax-Free's net assets reach $200
        million, whichever occurs first; or until Pennsylvania Tax-Free's net
        assets reach $125 million, whichever occurs first; or until Tax-Free
        Intermediate's net assets reach $100 million, whichever occurs first. In
        the absence of such waivers, the management fee, 12b-1 fee, other
        expenses and total operating expenses relating to Primary Shares would
        have been as follows: for Maryland Tax-Free, 0.55%, 0.25%, 0.13% and
        0.93% of average net assets; for Pennsylvania Tax-Free, 0.55%, 0.25%,
        0.20% and 1.00% of average net assets; and for Tax-Free Intermediate,
        0.55%, 0.25%, 0.26% and 1.06% of average net assets.
    (D) Each Fund has entered into an arrangement with its custodian whereby
        uninvested cash balances generate credits used to reduce custodian
        expenses. Other expenses and total operating expenses net of this
        reduction were as follows: for Maryland Tax-Free, the same; for
        Pennsylvania Tax-Free, 0.19% and 0.70%, respectively, of the Fund's
        average net assets; and for Tax-Free Intermediate, 0.26% and 0.70%,
        respectively, of the Fund's average net assets.

      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) redemption at the end of each time
      period. The Funds charge no redemption fees of any kind.

                              ----------------------------
Maryland Tax-Free:
  Assuming the maximum
    initial 2.75% sales
    charge                     $34    $49     $65     $112
  Assuming no initial sales
    charge                     $ 7    $22     $39     $ 87
Pennsylvania Tax-Free:
  Assuming the maximum
    initial 2.75% sales
    charge                     $34    $49     $65     $112
  Assuming no initial sales
    charge                     $ 7    $22     $39     $ 87
Tax-Free Intermediate:
  Assuming the maximum
    initial 2.00% sales
    charge                     $27    $42     $58     $105
  Assuming no initial sales
    charge                     $ 7    $22     $39     $ 87

          This example assumes that the maximum initial sales charge is deducted
      at the time of purchase, that the percentage amounts listed under Annual
      Fund Operating Expenses remain the same over the time periods shown and
      that all dividends and capital gain distributions are reinvested in
      additional Fund shares. If the waivers are not extended beyond July 31,
      1999, the expense figures in the examples will be higher.

          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
      the Adviser and Legg Mason waive their fees and the extent to which
      Primary Shares incur variable expenses, such as transfer agency costs.

          Because each Fund pays a 12b-1 fee with respect to Primary Shares,
      long-term investors 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 Fund expenses, see "The
      Funds' Management and Investment Adviser," page 22 and the "Funds'
      Distributor," page 23.

     PERFORMANCE INFORMATION

          From time to time each Fund may quote the TOTAL RETURN of a 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 of an investment in the fund, including changes in share
      price and assuming reinvestment of dividends and capital gain
      distributions. 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.
      Average annual returns, which differ from actual year-by-year results,
      tend to smooth out variations in a fund's return. The Funds' total returns
      reflect deduction of the maximum initial sales charge at the time of
      purchase.

          Total returns of Primary Shares as of March 31, 1998 were as follows:

                                 MARYLAND         PENNSYLVANIA        TAX-FREE

          Each Fund also may advertise its yield or tax equivalent yield. Yield
      reflects investment income net of expenses over a 30-day (or one-month)
      period on a Fund share, expressed as an annualized percentage of the
      maximum offering price per share at the end of the period. Tax equivalent
      yield shows the taxable yield an investor would have to earn before taxes
      to equal the Fund's tax-exempt yield. A tax equivalent yield is calculated
      by dividing a Fund's tax-exempt yield by the result of one minus a stated
      federal, state and local income tax rate. 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.

          Total return and yield information reflect past performance and are
      not predictions or guarantees of future results. Yields and total returns
      of Primary Shares of the Funds would be lower if the Adviser and Legg
      Mason had not waived a portion of the fees during the fiscal years 1992
      through 1998. Investment return and share price will fluctuate, and the
      value of your shares, when redeemed, may be worth more or less than their
      original cost. Further information about each Fund's performance is
      contained in the combined 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.

      Pennsylvania personal income tax. Tax-Free Intermediate is designed for
      intermediate-term investors who are able to benefit from income exempt
      from federal income tax. The value of Primary Shares can generally be
      expected to fluctuate inversely with changes in interest rates and,
      because of the potential negative impact of rising interest rates and
      other risks, the Funds would not be appropriate for investors whose
      primary goal is stability of principal. Each Fund is not intended to be a
      balanced investment program. Each Fund is not an appropriate investment
      for "substantial users" of certain facilities financed by industrial
      development or private activity bonds or related persons thereof. See
      "Taxes -- Federal Income Tax," page 19.

     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 Trust's Board
      of Trustees without a shareholder vote. There can be no assurance that any
      Fund will achieve its investment objective.

          MARYLAND TAX-FREE'S investment objective is to earn a high level of
      current income exempt from federal and Maryland state and local income
      taxes, consistent with prudent investment risk and preservation of
      capital. The Fund seeks to achieve its investment objective by investing
      primarily in debt instruments issued by or on behalf of the State of
      Maryland, its political subdivisions, municipalities, agencies,
      instrumentalities or public authorities, the interest on which, in the
      opinion of counsel to the issuers of those instruments, is exempt from
      federal and Maryland state and local income taxes. As a fundamental
      policy, under normal circumstances, the Fund will maintain at least 80% of
      its total assets in Maryland municipal obligations, exclusive of any such
      obligations the interest on which is a tax preference item for purposes of
      the federal alternative minimum tax ("Tax Preference Item"). See
      "Temporary Investments," page 10.

          PENNSYLVANIA TAX-FREE'S investment objective is to earn a high level
      of current income exempt from federal income tax and Pennsylvania personal
      income tax, consistent with prudent investment risk and preservation of
      capital. The Fund seeks to achieve its investment objective by investing
      primarily in debt instruments issued by or on behalf of the Commonwealth
      of Pennsylvania, its political subdivisions, municipalities, agencies,
      instrumentalities or public authorities, the interest on which, in the
      opinion of counsel to the issuers of those instruments, is exempt from
      federal income tax and Pennsylvania personal income tax. As a fundamental
      policy, under normal circumstances, the Fund will maintain at least 80% of
      its total assets in Pennsylvania municipal obligations, exclusive of any
      such obligations the interest on which is a Tax Preference Item. See
      "Temporary Investments" page 10.

          TAX-FREE INTERMEDIATE'S investment objective is to earn a high level
      of current income exempt from federal income tax, consistent with prudent
      investment risk. The Fund seeks to achieve its investment objective by
      investing primarily in debt instruments issued by or on behalf of states,
      territories and possessions of the United States, the District of Columbia
      and their respective authorities, agencies, instrumentalities and
      political subdivisions, the interest on which, in the opinion of counsel
      to the issuers of those instruments, is exempt from federal income tax
      ("municipal obligations"), while maintaining an average dollar-weighted
      maturity of between 2 and 10 years. As a fundamental policy, under normal
      circumstances, the Fund will maintain at least 80% of its total assets in
      municipal obligations, exclusive of any such obligations the interest on
      which is a Tax Preference Item. See "Temporary Investments" page 10.

          Each Fund invests in securities that, in the opinion of the Adviser,
      present acceptable credit risks and that, at the time of purchase, are
      rated:

          "Baa" or higher by Moody's, "BBB" or higher by S&P or Fitch in the
      case of bonds;

          "MIG-1" by Moody's, "SP-1" or higher by S&P or "F-1" or higher by
      Fitch in the case of notes;

          "P1" by Moody's, "A1" by S&P or "F-1" or higher by Fitch in the case
      of commercial paper; and

          "VMIG-1" by Moody's in the case of variable rate demand notes.

          Each Fund also invests in securities unrated by any of the above
      services which are deemed by the Adviser to be of comparable quality.

          The bond ratings noted above are considered "investment grade" by the
      respective rating agencies. A rating of a municipal obligation represents
      the rating agency's opinion regarding its quality and is not a guarantee
      of quality. Moody's considers bonds rated in its fourth highest category
      (I.E., Baa) 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 higher rated bonds. In the event the rating
      on an issue held in
8

<PAGE>

      a Fund's portfolio is changed by Moody's, S&P or Fitch, such change will
      be considered by the Adviser in its evaluation of the overall investment
      merits of that security. If, as a result of any downgradings by Moody's,
      S&P or Fitch, or, for unrated securities, any determinations by the
      Adviser that securities are no longer of comparable quality to investment
      grade securities, more than 5% of a Fund's total assets are represented by
      securities rated below investment grade or the equivalent, the Adviser
      will, as soon as practicable consistent with achieving an orderly
      disposition of the securities, sell such holdings until they represent 5%
      or less of the Fund's total assets. A discussion of the ratings outlined
      above is included in the Statement of Additional Information.

          In addition to the agency ratings, there are other criteria which will
      be used by the Adviser in selecting securities for a portfolio.
      Consideration will be given to the maturity and duration of each bond as
      well as its effect on the overall average maturity and duration of the
      portfolio. Analysis of the current and historical yield spreads is done to
      determine the relative value in any bond considered for purchase. The
      coupon level and call features also figure in the decision on the relative
      merits of an investment. Consideration is also given to the type of
      bond -- whether it is a general obligation or a revenue bond. In addition
      to this examination of bond characteristics, significant effort is devoted
      to analysis of the creditworthiness of the bond issuer at the time of
      purchase and on an ongoing basis.

          Each Fund is permitted to invest in municipal securities of any
      maturity. The maturities of a Fund's portfolio securities will reflect the
      Adviser's judgment concerning current and future market conditions as well
      as other factors, such as the Fund's liquidity needs. Under normal
      circumstances, the dollar-weighted average maturities of Maryland
      Tax-Free's and Pennsylvania Tax-Free's portfolios are expected to be
      between 12 and 24 years and the dollar-weighted average maturity of
      Tax-Free Intermediate's portfolio is expected to be between 2 and 10
      years.

          Each Fund does not expect its portfolio turnover rate to exceed 90%
      per year.

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. Other public purposes for which
      municipal obligations may be issued include the refunding of outstanding
      obligations, the obtaining of funds for general operating expenses and the
      making of loans to other public institutions and facilities. In addition,
      certain types of industrial development bonds ("IDBs") and private
      activity bonds ("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. Interest on certain
      tax-exempt PABs will constitute a Tax Preference Item. Accordingly, under
      normal circumstances, each Fund's investment in obligations, the interest
      on which is such an item, including PABs, will be limited to a maximum of
      20% of its total assets.

          Municipal obligations also include short-term tax anticipation notes,
      bond anticipation notes, revenue anticipation notes and other forms of
      short-term debt obligations. Such notes may be issued with a short-term
      maturity in anticipation of the receipt of tax payments, the proceeds of
      bond placements or other revenues.

          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. "Certificates of Participation" are participations in municipal
      lease obligations or installment sales contracts. Each certificate
      represents a proportionate interest in or right to the lease purchase
      payments made.

          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
                                                                               9

<PAGE>

      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. IDBs and 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.

TEMPORARY INVESTMENTS
          During unusual market conditions, including if, in the Adviser's
      opinion, there are insufficient suitable Maryland municipal obligations
      (with respect to Maryland Tax-Free), Pennsylvania municipal obligations
      (with respect to Pennsylvania Tax-Free) or municipal obligations (with
      respect to Tax-Free Intermediate) available that pay interest that is not
      a Tax Preference Item, a Fund temporarily may invest more than 20% of its
      total assets in municipal obligations the interest on which is exempt from
      federal income tax but is such an item (with respect to Tax-Free
      Intermediate) and/or is subject to Maryland state and local income taxes
      (with respect to Maryland Tax-Free) and/or is subject to Pennsylvania
      personal income tax (with respect to Pennsylvania Tax-Free). Each Fund
      expects that under normal circumstances it will maintain needed liquidity
      through the purchase of short-term municipal securities. However, for
      liquidity purposes, or pending the investment of the proceeds of the sale
      of shares, a Fund temporarily may invest in taxable short-term investments
      consisting of: obligations of the U.S. Government, its agencies and
      instrumentalities; certificates of deposit and bankers' acceptances of
      U.S. domestic banks with assets of one billion dollars or more; commercial
      paper or other corporate notes of high quality; and any of such items
      subject to short-term repurchase agreements. Each Fund may invest without
      limit in such instruments for temporary, defensive purposes, when in the
      Adviser's opinion, no suitable municipal securities are available. No more
      than 10% of a Fund's net assets will be invested in repurchase agreements
      maturing in more than seven days and other illiquid securities. Interest
      earned from such taxable investments will be taxable to investors as
      ordinary income when distributed to them.

          As a fundamental policy, each Fund may borrow money solely for
      temporary purposes from banks or by engaging in reverse repurchase
      agreements in an amount up to 10% of the value of its total assets;
      however, borrowings by a Fund in excess of 5% of the value of its total
      assets may be only from banks.

YIELD AND RISK FACTORS

      Yield
          The yield of a municipal obligation is dependent on a variety of
      factors, including general municipal securities market conditions, general
      fixed-income market conditions, the financial condition of the issuer, the
      size of the particular offering, the maturity of the obligation, the
      credit quality and rating of the issue and expectations regarding changes
      in income tax rates.

      Interest Rate Risk
          If general market interest rates increase, the prices of municipal
      obligations ordinarily will decrease. In a market of decreasing interest
      rates, the opposite generally will be true. Although longer-term bonds
      generally offer higher yields than shorter-term bonds, their prices are
      more sensitive to changes in interest rates than bonds with shorter
      maturities. Under normal circumstances, the dollar-weighted average
      maturities of Maryland Tax-Free's and Pennsylvania Tax-Free's portfolios
      are expected to be 12-24 years and the dollar-weighted average maturity of
      Tax-Free Intermediate's portfolio is expected to be 2-10 years.

      For Maryland Tax-Free:
          Changes in economic conditions in, or governmental policies of, the
      State of Maryland could have a significant impact on the performance of
      the Fund. For example, services (including mining), wholesale and retail
      trade, government, and manufacturing (primarily printing and publishing,
      food and kindred products, instruments and related products, electronic
      equipment, industrial machinery and transportation equipment) are the
      leading areas of employment in the State of Maryland. In contrast to the
      nation as a whole, more
10

<PAGE>

      people in Maryland are employed in government than in manufacturing. The
      relatively high concentration of governmental employment in Maryland makes
      the state potentially vulnerable to any decreases in federal, including
      military, and state governmental spending.

          The Fund may invest in certain municipal obligations with unique
      risks. These include, but are not limited to, securities issued by
      hospitals and other healthcare providers. The hospital industry throughout
      the nation has been subjected to pressure to reduce expenses and to limit
      lengths of stay. That pressure may adversely affect the financial health
      of some hospitals.

          An expanded discussion of certain investment considerations relating
      to debt obligations of Maryland and its political subdivisions is
      contained in the Statement of Additional Information.

      For Pennsylvania Tax-Free:
          Changes in economic conditions in, or governmental policies of, the
      Commonwealth of Pennsylvania could have a significant impact on the
      performance of the Fund. For example, Pennsylvania's continued dependence
      on manufacturing, mining and steel has made Pennsylvania vulnerable to
      cyclical industry fluctuations, foreign imports and environmental
      concerns. However, growth in the service and trade sectors has helped
      diversify Pennsylvania's economy and reduce its unemployment rate below
      the national average. Changes in local economic conditions or local
      governmental policies within Pennsylvania, which can vary substantially by
      region, could also have a significant impact on the performance of
      municipal obligations held by the Fund. The City of Philadelphia, for
      example, experienced severe financial problems which impaired its ability
      to borrow money and adversely affected the ratings of its obligations and
      their marketabilty. While the Fund may invest in obligations that are
      secured by obligors other than Pennsylvania or its political subdivisions
      (such as hospitals, universities, corporate obligors and corporate credit
      and liquidity providers) and obligations limited to specific revenue
      pledges (such as sewer authority bonds), the creditworthiness of these
      obligors may be partly dependent on the creditworthiness of Pennsylvania
      or its municipal authorities.

          An expanded discussion of certain investment considerations relating
      to debt obligations of Pennsylvania and its political subdivisions is
      contained in the Statement of Additional Information.

      Concentration
          Each Fund may invest 25% or more of its total assets in a particular
      segment of the municipal securities market, such as hospital revenue
      bonds, housing agency bonds, IDBs or airport bonds, or in securities the
      interest on which is paid from revenues of a similar type of project. In
      such circumstances, economic, business, political or other changes
      affecting one issue of bonds (such as proposed legislation affecting
      healthcare or the financing of a project, shortages or price increases of
      needed materials, or declining markets or needs for the projects) would
      most likely affect other bonds in the same segment, thereby potentially
      increasing market risk. As a result, each Fund is subject to greater risk
      than other funds that do not follow this practice.

      Non-Diversification
          Each Fund has registered as a "non-diversified" investment company.
      Therefore, the percentage of Fund assets invested in any single issuer is
      not limited by the Investment Company Act of 1940, as amended ("1940
      Act"). However, each Fund intends to continue to qualify as a regulated
      investment company ("RIC") under the Internal Revenue Code of 1986, as
      amended ("Code"). To qualify as a RIC, a Fund generally must meet the
      following diversification requirements at the close of each quarter of its
      taxable year: (1) at least 50% of the value of its total assets must
      consist of cash, securities of the U.S. Government and other RICs and
      holdings of other securities, which, with respect to any one issuer, do
      not have a value greater than 5% of the value of the Fund's total assets;
      and (2) no more than 25% of the value of its total assets may be invested
      in the securities of a single issuer. For these purposes, the term
      "issuer" does not include the U.S. Government or other RICs. To the extent
      that a Fund's assets are invested in the obligations of a limited number
      of issuers, the value of that Fund's shares will be more susceptible to
      any single economic, political or regulatory occurrence affecting one or
      more of
                                                                              11

<PAGE>

      those issuers than the shares of a diversified investment company would
      be.

      Other Risks
          Current efforts to restructure the federal budget and the relationship
      between the federal government and state and local governments may impact
      the financing of some issuers of municipal securities. Some states and
      localities at times experience substantial deficits and may find it
      difficult for political or economic reasons to increase taxes. Some local
      jurisdictions have invested heavily in derivative instruments and may now
      hold portfolios of uncertain valuation. Each of these factors may affect
      the ability of an issuer of municipal securities to meet its obligations.
      Efforts by Congress to restructure the federal income tax system could
      adversely affect the value of municipal securities.

INVESTMENT TECHNIQUES
          Each Fund may employ the investment techniques described below, among
      others. Use of certain of these techniques may give rise to taxable
      income.

      When-Issued Securities
          Each Fund may enter into commitments to purchase municipal obligations
      or other securities on a when-issued basis. Such securities are often the
      most efficiently priced and have the best liquidity in the bond market.
      When a Fund purchases securities on a when-issued basis, it assumes the
      risks of ownership, including the risk of price fluctuation, at the time
      of purchase, not at the time of receipt. However, a Fund does not have to
      pay for the obligations until they are delivered to it, normally 15 to 45
      days later. To meet its payment obligation, a Fund will establish a
      segregated account with its custodian and maintain cash or appropriate
      liquid obligations in an amount at least equal to the payment that will be
      due. Use of this practice would have a leveraging effect on a Fund. Each
      Fund does not expect that its commitment to purchase when-issued
      securities will at any time exceed, in the aggregate, 25% of total assets.

      Callable Bonds
          Callable municipal bonds are municipal bonds which carry a provision
      permitting the issuer to redeem the bonds prior to their maturity dates at
      a specified price which typically reflects a premium over the bonds'
      original issue price. If the proceeds of a bond owned by a Fund called
      under circumstances favorable to the issuer are reinvested, the result may
      be a lower overall yield on such proceeds upon reinvestment because of
      lower prevailing interest rates. If the purchase price of such bonds
      included a premium related to the appreciated value of the bonds, some or
      all of that premium may not be recovered by bondholders, such as the
      Funds, depending on the price at which such bonds were redeemed.

          Each callable bond is "marked-to-market" daily based on the bond's
      call date so that the call of some or all of a Fund's callable bonds is
      not expected to have a material impact on that Fund's net asset value. In
      light of the previously described pricing policies and because each Fund
      follows certain amortization procedures required by the Internal Revenue
      Service, each Fund does not expect to suffer any material adverse impact
      in connection with a call of bonds purchased at a premium. Notwithstanding
      such policies, however, as with any investment strategy, there is no
      guarantee that a call may not have a more substantial impact than
      anticipated.

      Stand-By Commitments
          Each Fund may acquire "stand-by commitments" with respect to its
      investments in municipal obligations. A stand-by commitment is a put (that
      is, the right to sell the underlying security within a specified period of
      time at a specified exercise price that may be sold, transferred or
      assigned only with the underlying security) that entitles the Fund to
      same-day settlement. Under a stand-by commitment, a broker, dealer or bank
      agrees to purchase, at the Fund's option, specified municipal obligations
      at amortized cost plus accrued interest. The total amount paid for
      outstanding stand-by commitments held by a Fund will not exceed 25% of
      that Fund's total assets calculated immediately after each stand-by
      commitment is acquired.
12

<PAGE>

      Securities Lending, Zero Coupon and Deferred Interest Bonds
          Each Fund may engage in securities lending and may invest in zero
      coupon and deferred interest bonds. However, each Fund does not currently
      intend to loan securities with a value exceeding 5% of its net assets or
      to invest more than 5% of its net assets in zero coupon and deferred
      interest bonds. Any income from securities lending would be taxable when
      distributed to shareholders. For further information concerning securities
      lending, zero coupon and deferred interest bonds, see the Statement of
      Additional Information.

      Variable Rate and Floating Rate Obligations
          Each Fund may invest in variable rate municipal obligations and notes.
      Variable rate obligations have an interest rate that is adjusted
      periodically based upon market conditions.

          Each Fund may also invest in floating rate and variable rate demand
      notes. Demand notes provide that the holder may demand payment of the note
      at its par value plus accrued interest. These notes may be supported by an
      unconditional bank letter of credit guaranteeing payment of the principal
      or both the principal and accrued interest. Because each Fund invests in
      such securities backed by banks and other financial institutions, changes
      in the credit quality of these institutions could cause losses to a Fund.
      Floating rate demand notes have an interest rate related to a known
      lending rate, such as the prime rate, and are automatically adjusted when
      such known rate changes. Such securities often react to changes in market
      interest rates in a manner similar to shorter-term securities that mature
      at the time of the next interest rate reset for the variable or floating
      rate instrument. In calculating its dollar-weighted average maturity, a
      Fund may determine the maturity of a variable or floating rate note
      according to the interest rate reset date, or the date principal can be
      recovered on demand, rather than the date of ultimate maturity.

      Futures and Option Strategies
          To protect against the effect of adverse changes in interest rates,
      each Fund may purchase and sell interest rate futures contracts and
      options on securities indexes, and may purchase put options on interest
      rate futures contracts (practices known as "hedging"). A Fund may purchase
      put options on interest rate futures contracts or sell interest rate
      futures contracts (that is, enter into a futures contract to sell the
      underlying security) to attempt to reduce the risk of fluctuations in its
      share value. A Fund may purchase an interest rate futures contract (that
      is, enter into a futures contract to purchase the underlying security) to
      attempt to establish more definitely the return on securities the Fund
      intends to purchase. The Funds may not use these instruments for
      speculation or leverage. In addition, a Fund's ability to use these
      strategies may be limited by market conditions, regulatory limits and tax
      considerations. Any gains from futures and options transactions would be
      taxable.

          The success of a Fund's strategies in reducing risks depends on many
      factors, the most significant of which is the Adviser's ability to predict
      market interest rate changes correctly, which differs from its ability to
      select portfolio securities. In addition, a hedge could be unsuccessful if
      the changes in the value of a Fund's futures contract or option positions
      do not correlate to the changes in the value of its investments. It is
      also possible that a Fund may be unable to purchase or sell a portfolio
      security at a time that otherwise would be favorable for it to do so, or
      that a Fund may need to sell a portfolio security at a disadvantageous
      time, due to the need for the Fund to maintain "cover" or to segregate
      securities in connection with hedging transactions. Because the markets
      for futures and options are not always liquid, a Fund may be unable to
      close out or liquidate its hedged position and may be locked in during a
      market decline. The Adviser attempts to minimize the possible negative
      effects of these factors through careful selection and monitoring of each
      Fund's futures and options positions. The Adviser is of the opinion that a
      Fund's investments in futures transactions will not have a material
      adverse effect on that Fund's liquidity or ability to honor redemptions.

          The purchase and sale of options and futures contracts involve risks
      different from those involved with direct investments in securities, and
      also require different skills from the Adviser in managing the portfolios.
      While utilization of options, future contracts and similar instruments
                                                                              13

      may be advantageous to a Fund, if the Adviser is not successful in
      employing such instruments in managing a Fund's investments or in
      predicting interest rate changes, that Fund's performance will be worse
      than if the Fund did not use such instruments. In addition, a Fund will
      pay commissions and other costs in connection with such investments, which
      may increase that Fund's expenses and reduce its yield. A more complete
      discussion of the possible risks involved in transactions in options and
      futures contracts is contained in the Statement of Additional Information.

          Each Fund's current policy is to limit options and futures
      transactions to those described above. Each Fund currently does not intend
      to purchase put and call options having a value in excess of 5% of its
      total assets.

INVESTMENT LIMITATIONS
          Each Fund has adopted certain fundamental limitations that, like its
      investment objective, can be changed only by the vote of a majority of the
      outstanding voting securities of that Fund. For these purposes, 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 in person or by proxy. These investment limitations are set
      forth under "Additional Information About Investment Limitations and
      Policies" in the Statement of Additional Information. Fund policies,
      unless described as fundamental, can be changed by the Board of Trustees.

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.

          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, is $1,000, and the minimum investment for each purchase of
      additional shares is $100. For those investing through a Fund's Future
      First Systematic Investment Plan, payroll deduction plans and plans
      involving automatic payment of funds from financial institutions 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 of the Funds:

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.

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 Funds 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
14

<PAGE>

      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 a Financial Advisor
      or Service Provider.

          Primary Share purchases will be processed at the net asset value next
      determined (plus any applicable sales charge, which will vary with the
      amount purchased, as shown below) after your Financial Advisor or Service
      Provider has received your order. The sales charge on each of the Funds
      will be waived for all shares purchased through July 31, 1999. After July
      31, 1999, any exchanges of shares purchased pursuant to the sales charge
      waiver will be subject to any sales charge imposed by the fund into which
      you are exchanging since no sales charge was paid on the initial purchase.

          Shares of any Fund may be obtained without a sales charge by
      exchanging shares of another Fund for which an equal or higher sales
      charge was paid, or by exchanging shares of other Legg Mason funds which
      were originally obtained through exchange of Fund shares on which an equal
      or higher sales charge was paid. If the sales charges previously paid were
      less than sales charges on the Fund into which you are exchanging, an
      additional sales charge equal to the difference is due. In addition, Fund
      shares may be purchased without a sales charge by employees, directors and
      officers of Legg Mason or its affiliates, directors or trustees and
      officers of any of the Legg Mason funds, the spouses and children under 21
      years of age of any of the foregoing persons and by advisory clients of
      investment advisers affiliated with Legg Mason.

          Shareholders who have redeemed shares on which a sales charge was paid
      may reinstate their Fund account without a sales charge up to the dollar
      amount redeemed by purchasing shares within 90 days of the redemption
      ("reinstatement privilege"). Shareholders may exercise their reinstatement
      privilege by notifying their Financial Advisor or Service Provider of such
      desire and placing an order for the amount to be purchased within 90 days
      after the date of redemption. The reinstatement will be made at the net
      asset value next determined after the Notice of Reinstatement and order
      have been received by Legg Mason's Funds Processing.

          Primary Shares may be purchased at reduced sales charges through
      either of the two Legg
                                                                              15

      Mason reduced sales charge plans. These are (1) a Letter of Intention
      ("LOI") and (2) a Right of Accumulation, as described below.

          Through an LOI, you may pay a lower sales charge if the dollar amount
      of shares currently being purchased plus the dollar amount of any
      purchases you intend to make during the next thirteen months of shares of
      these and other Legg Mason funds sold with an initial sales charge equals
      $50,000 or more. To take advantage of an LOI, you should indicate the
      total amount you intend to purchase over the thirteen-month period on the
      form available from your Financial Advisor or Service Provider. Holdings
      acquired up to 90 days before the LOI is filed will be counted toward
      completion of the LOI, and will be entitled to a retroactive downward
      adjustment of the initial sales charge.

          If the Funds' transfer agent, BFDS, does not receive a completed LOI
      within 20 business days after settlement of the first LOI purchase or if
      the total purchases indicated on the LOI are not made within the
      thirteen-month period, your account will be charged with the difference
      between the reduced LOI sales charge and the sales charge applicable to
      the purchase actually made. Shares with a value of up to 2 1/2% of the
      intended LOI purchases will be held in escrow during the thirteen-month
      period (registered in your name) to assure such necessary payment. These
      escrowed shares may not be exchanged for shares of other Legg Mason funds.
      If you redeem your account during this period, the applicable Fund will
      withhold from the escrow amount sufficient shares to pay any unpaid sales
      charge.

          Under the Right of Accumulation, the current value of an investor's
      existing shares in Legg Mason funds sold with an initial sales charge may
      be combined with the amount of the investor's current purchase in
      determining the sales charge for the current purchase. In determining both
      the current value of existing shares and the amount of the investor's
      current purchase, shares held or purchased by the investor's spouse,
      and/or children under the age of 21, may be included. Legg Mason may
      require supporting documentation in connection with purchases made under
      the Right of Accumulation.

          Orders 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, plus any
      applicable sales charge, determined as of the close of the Exchange on
      that day. Orders 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, plus any applicable sales charge,
      determined as of the close of the Exchange on the next day the Exchange is
      open. See "How Net Asset Value is Determined," page 18. Payment must be
      made within three business days to Legg Mason. 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
      established automatically 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
          There are two ways you can redeem your Primary Shares. First, you may
      give your Financial Advisor or Service Provider an order for redemption of
      your shares in person or by telephone. 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
16

<PAGE>

      Funds Processing, P.O. Box 1476, Baltimore, Maryland 21203-1476.

          Requests for redemption 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.

          Proceeds from your redemption 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 may not be disbursed unless the Fund can be
      reasonably assured that the check has been collected.

          Written requests for redemption must be in "good order." 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.

          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. Each Fund may request identifying
      information from callers or employ identification numbers. Each Fund may
      be 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 or Service Provider 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 you. However, no Fund will 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.

          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 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.)

          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.
                                                                              17

HOW NET ASSET VALUE IS DETERMINED
          Net asset value per Primary 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 Primary Shares from the total
      assets attributable to such shares and dividing the result by the number
      of Primary 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 based upon appraisals received from an independent 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. Debt securities with
      remaining maturities of 60 days or less are valued at amortized cost,
      unless conditions otherwise indicate. Other securities are valued at fair
      value as determined by, or under the supervision of, the Board of Trustees
      of the Trust.

DIVIDENDS AND OTHER DISTRIBUTIONS
          Dividends from net investment income of each Fund are declared daily
      and paid monthly. Shareholders begin to earn dividends on their Primary
      Shares as of the settlement date, which is normally the third business day
      after their orders are placed with their Financial Advisor or Service
      Provider. Dividends from any 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), if any, 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.

          Dividends and capital gain distributions on shares held by
      shareholders maintaining a Systematic Withdrawal Plan generally are
      reinvested in Primary Shares on the payment dates. Other shareholders may
      elect to:

          1. Receive both dividends and capital gain distributions in Primary
      Shares of the distributing Fund;

          2. Receive dividends in cash and capital gain distributions in Primary
      Shares of the distributing Fund;

          3. Receive dividends in Primary Shares of the distributing Fund and
      capital gain distributions in cash; or

          4. Receive both dividends and capital gain distributions in cash.

          If a shareholder has elected to receive dividends and/or capital gain
      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 capital gain distributions reinvested in
      additional Primary Shares. No interest will accrue on amounts represented
      by uncashed distribution or redemption checks.

          In certain cases, you may reinvest your dividends and capital gain
      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 capital gain 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
      capital gain 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 capital gain distributions paid to shareholders as of that
      date.

TAXES

FEDERAL INCOME TAX
          Each Fund intends to continue to qualify for treatment as a RIC under
      the Code so that it will be relieved of federal income tax on that part of
      its investment company taxable income (generally, taxable net investment
      income and any net short-term capital gain) and net capital gain that it
      distributes to its shareholders. If a Fund so qualifies and, at the close
      of each quarter of its taxable year, at least 50% of the value of its
      total assets consists of certain obligations the interest on which is
      excludable from gross income under Section 103(a) of the Code, that Fund
      may pay "exempt-interest" dividends to its shareholders. Those dividends
      constitute the portion of the aggregate dividends (excluding capital gain
      distributions), as designated by the Fund, equal to the excess of the
      Fund's excludable interest over certain amounts disallowed as deductions.
      Exempt-interest dividends are excludable from a shareholder's gross
      income; however, the amount of such dividends must be reported on the
      recipient's federal income tax return.

          If and to the extent a Fund receives interest on certain PABs, a
      proportionate part of the exempt-interest dividends paid by the Fund will
      be treated as a Tax Preference Item. In addition, exempt-interest
      dividends received by a corporate shareholder may be indirectly subject to
      the federal alternative minimum tax without regard to whether the
      distributing Fund's tax-exempt interest is attributable to PABs.

          To the extent dividends are derived from taxable income from temporary
      investments, from net short-term capital gain or from the use of certain
      investment techniques described in "Investment Objectives and Policies,"
      page 8, they are taxable to shareholders as ordinary income (whether paid
      in cash or reinvested in Primary Shares). No portion of those dividends
      will qualify for the corporate dividends-received deduction. Distributions
      derived from net capital gain, if any, are taxable to shareholders as
      long-term capital gain regardless of the length of time they have held
      their Primary Shares (and irrespective of whether those distributions are
      paid in cash or reinvested in Primary Shares). The maximum tax rate
      applicable to a noncorporate taxpayer's net capital gain recognized on
      capital assets held for more than one year is 20% (10% for taxpayers in
      the 15% marginal tax bracket). In the case of a RIC such as the Funds, the
      relevant holding period is determined by how long the Fund has held the
      portfolio security on which the gain was realized, not by how long you
      have held your Fund shares.

          Interest on indebtedness incurred or continued by a shareholder to
      purchase or carry Primary Shares generally is not deductible. Persons who
      are "substantial users" (or related persons) of facilities financed by
      IDBs or PABs should consult their tax advisers before purchasing shares of
      a Fund because, for users of certain of these facilities, the interest on
      those bonds is not exempt from federal income tax. For these purposes, a
      "substantial user" includes a non-exempt person who regularly uses in
      trade or business a part of a facility financed from the proceeds of IDBs
      or PABs.

          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 (which normally includes any sales charge paid). An exchange of
      Primary Shares of any Fund for shares of any other Legg Mason fund
      generally will have similar tax consequences. However, special tax rules
      apply if (1) a shareholder disposes of Primary Shares through a redemption
      or exchange within 90 days after the shareholder acquired the shares and
      (2) the shareholder subsequently acquires Primary Shares of that Fund or
      of another Legg Mason fund without the imposition of a sales charge that
      otherwise would have been imposed except for the reinstatement privilege
      or exchange privilege. See "How You Can Invest in the Funds," page 14, and
      "Shareholder Services -- Exchange Privilege," page 21. In these cases, any
      sales charge that was imposed on the purchase of the original Primary
      Shares will not be taken into account in determining the amount of gain or
      loss on the redemption or exchange -- the tax effect of that charge will
      instead be deferred by being treated as having been incurred in connection
      with the newly acquired shares. In addition, if Primary Shares are
                                                                              19

<PAGE>

      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.

          Each Fund is required to withhold 31% of all taxable 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 taxable dividends and capital gain
      distributions payable to such shareholders who otherwise are subject to
      backup withholding.

FOR MARYLAND TAX-FREE:

MARYLAND TAXES
          Distributions paid by Maryland Tax-Free to Maryland residents
      attributable to interest received or capital gains recognized by the Fund
      on Maryland municipal obligations are exempt from Maryland state and local
      income taxes. Distributions attributable to interest received or capital
      gains recognized by the Fund on certain U.S. government obligations also
      are exempt from Maryland state and local income taxes. Distributions
      attributable to the Fund's other income or gains generally are subject to
      these taxes.

          Interest on indebtedness incurred by a shareholder to purchase or
      carry Fund shares generally is not deductible for purposes of either
      Maryland state or local income tax. Fund shares held by an individual are
      not subject to the Maryland personal property tax. Fund shares held by a
      corporation also are not subject to the Maryland personal property tax.
      Dividends paid by the Fund with respect to Maryland municipal obligations
      and profits realized on the sale or exchange of such obligations are not
      subject to the Maryland Franchise Tax imposed on "financial institutions"
      and measured by net earnings.

          In the case of individuals, Maryland imposes an income tax on Tax
      Preference Items. Interest paid on certain PABs is a Tax Preference Item.
      Accordingly, if the Fund holds such bonds, 50% of the interest thereon in
      excess of a threshold amount is subject to Maryland state and local tax.

          Dividends derived from interest on Maryland municipal obligations may
      not be exempt from taxation under the laws of states other than Maryland.

FOR PENNSYLVANIA TAX-FREE:

PENNSYLVANIA TAXES
          Individual shareholders of Pennsylvania Tax-Free who are otherwise
      subject to the Pennsylvania personal income tax will not be subject to
      that tax on distributions by the Fund that are attributable to interest on
      Pennsylvania municipal obligations. Distributions attributable to most
      other sources, including gains, will not be exempt from Pennsylvania
      personal income tax.

          Shares that are held by individual shareholders who are Pennsylvania
      residents will be exempt from the Pennsylvania county personal property
      tax to the extent that the Fund's portfolio consists of Pennsylvania
      municipal obligations on the annual assessment date. Nonresidents of
      Pennsylvania are not subject to this tax. Corporations are not subject to
      any of these personal property taxes. For shareholders who are residents
      of the City of Philadelphia, distributions of interest derived from
      Pennsylvania municipal obligations are not taxable for purposes of the
      Philadelphia School District investment net income tax, provided that the
      Fund reports to its shareholders the percentage of Pennsylvania municipal
      obligations held by it for the year. The Fund will report such percentage
      to its shareholders.

          Distributions of interest, but not gains, realized on Pennsylvania
      municipal obligations are not subject to the Pennsylvania corporate net
      income tax. The Pennsylvania Department of Revenue also takes the position
      that shares of funds similar to the Fund are not considered exempt assets
      of a corporation for the purposes of determining its capital stock value
      subject to Pennsylvania capital stock and franchise taxes.

          Dividends derived from interest on Pennsylvania municipal obligations
      may not be exempt from taxation under the laws of states other than
      Pennsylvania.

GENERAL
          Shareholders receive information after the close of each year
      concerning the tax status of all dividends and capital gain distributions
      from their Fund(s).

          The foregoing is only a summary of some of the important federal,
      Maryland, Pennsylvania and certain local income tax considerations
      generally affecting the Funds and their shareholders; see the Statement of
      Additional Information for a further discussion. In addition to those
      considerations, which are applicable to any investment in the Funds, there
      may be other federal, state or local tax considerations applicable to a
      particular investor. 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
          You will receive from Legg Mason a confirmation after each transaction
      involving Primary Shares (except a reinvestment of dividends or capital
      gain distributions and purchases made through the Future First Systematic
      Investment Plan or through automatic investments).

          An account statement will be sent to you monthly unless there has been
      no activity in the account or you are purchasing shares only through the
      Future First Systematic Investment Plan or through automatic investments,
      in which case an account statement will be sent quarterly. 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 its 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."

SYSTEMATIC WITHDRAWAL PLAN
          You may elect to make systematic withdrawals from your Fund account of
      a minimum of $50 on a monthly basis if you are purchasing or already own
      shares with a net asset value of $5,000 or more. Shareholders should not
      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 the corresponding class of 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 an
      additional sales charge if the sales charge previously paid was less than
      the sales charge applicable to the fund into which you are exchanging,
      determined on the same business day as redemption of the Fund shares you
      wish to redeem. Exchanges from the other Legg Mason funds sold without an
      initial sales charge will be made at net asset value plus the applicable
      sales charge (unless the investment in the fund was transferred from a
      Legg Mason fund sold with the same or higher sales charge).

          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 "How You Can Redeem
      Your Primary Shares," page 16. 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
      its
                                                                              21

      exchange privilege upon 60 days' notice to shareholders. Some Service
      Providers may not offer all of the Legg Mason funds for exchange.

THE FUNDS' MANAGEMENT AND INVESTMENT ADVISER

BOARD OF TRUSTEES
          The business and affairs of each Fund are managed under the direction
      of the Board of Trustees of the Trust.

ADVISORY AGREEMENTS
          Pursuant to separate advisory agreements with each Fund (each an
      "Advisory Agreement"), which were approved by the Trust's Board of
      Trustees, the Adviser, a wholly owned subsidiary of Legg Mason, Inc. (a
      financial services holding company), serves as each Fund's investment
      adviser. The Adviser acts as the portfolio manager for each Fund and is
      responsible for the actual investment management of the Funds, including
      the responsibility for making investment decisions and placing orders to
      buy, sell or hold a particular security. Each Fund pays the Adviser,
      pursuant to the Advisory Agreement, an advisory fee equal to an annual
      rate of 0.55% of the Fund's average daily net assets attributable to
      Primary Shares. Because of fee waivers (see below), the Funds paid
      advisory fees for the fiscal year ended March 31, 1998 as follows:

      Maryland Tax-Free:                              .32%
      Pennsylvania Tax-Free:                          .26%
      Tax-Free Intermediate:                          .19%

FEE WAIVERS
          The Adviser and Legg Mason have agreed to waive advisory and 12b-1
      fees in any month to the extent a Fund's expenses related to Primary
      Shares (exclusive of taxes, interest, brokerage and extraordinary
      expenses) during that month exceed an annual rate of 0.70% of that Fund's
      average daily net assets attributable to Primary Shares. This waiver
      expires on July 31, 1999, or when a Fund's assets reach the following
      levels:

      Maryland Tax-Free:                       $200 million
      Pennsylvania Tax-Free:                   $125 million
      Tax-Free Intermediate:                   $100 million

          These agreements are voluntary and may be terminated by the Adviser
      and Legg Mason at any time. Each Fund pays all its other expenses which
      are not assumed by the Adviser.

PRIMARY SHARES EXPENSE RATIOS
          For the fiscal year ended March 31, 1998, the ratio of each Fund's
      expenses to its average net assets (after application of any fee waivers)
      was:

      Maryland Tax-Free:                             0.70%
      Pennsylvania Tax-Free:                         0.70%
      Tax-Free Intermediate:                         0.70%

ADVISER
          The Adviser acts as adviser to private accounts and investment company
      portfolios with a value as of June 30, 1998 of approximately $3 billion.
      The Adviser's address is 100 Light Street, Baltimore, Maryland 21202.

ADMINISTRATION AGREEMENT
          Pursuant to an agreement with the Adviser ("Administration
      Agreement"), which was approved by the Trust's Board of Trustees, LMFA
      serves as the Trust's administrator. LMFA manages the affairs of the Trust
      and provides the Trust with office facilities and personnel reasonably
      necessary for the operation of the Trust. The Adviser pays LMFA, pursuant
      to the Administration Agreement, a fee equal to an annual rate of 0.05% of
      each Fund's average daily net assets.

          LMFA acts as investment adviser or manager to eighteen investment
      company portfolios and to private accounts. Aggregate assets under
      management totaled approximately $12.2 billion as of June 30, 1998.

YEAR 2000
          Like other mutual funds, financial and business organizations around
      the world, the Trust could be adversely affected if the computer systems
      used by its investment adviser 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
22

<PAGE>

      the "Year 2000 Problem." The Adviser is taking steps that it believes are
      reasonably designed to address the Year 2000 Problem with respect to the
      computer systems that it uses and to obtain assurances that comparable
      steps are being taken by the Trust's 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.

PORTFOLIO MANAGEMENT
          Victoria M. Schwatka has been primarily responsible for the day-to-day
      management of the Funds since their inception. Ms. Schwatka is a portfolio
      manager and Senior Vice-President of Legg Mason's Fixed Income Group. Ms.
      Schwatka has been employed by Legg Mason since June, 1986.

          Jane E. Trust became co-manager of the Trust on July 31, 1997. Ms.
      Trust has been a Vice President of the Adviser since July 1994, and a
      portfolio manager for Legg Mason's Fixed Income Group since 1991.

THE FUNDS' DISTRIBUTOR
          Legg Mason, a wholly owned subsidiary of Legg Mason, Inc., is the
      distributor of the Funds' shares pursuant to a separate Underwriting
      Agreement with each Fund. Each Underwriting Agreement obligates Legg Mason
      to pay certain expenses in connection with the offering of shares of the
      Funds, 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 periodic 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. Legg Mason receives the sales
      charge imposed on the purchase of Primary Shares.

          The Trust's Board of Trustees has adopted a Distribution and
      Shareholder Services Plan ("Plan") pursuant to Rule 12b-1 under the 1940
      Act. The Plan provides that as compensation for its ongoing services to
      investors in Primary Shares and its activities and expenses related to the
      sale and distribution of Primary Shares, Legg Mason receives from each
      Fund annual service and distribution fees payable from the assets
      attributable to Primary Shares, each equal to an annual rate of 0.125% of
      that Fund's average daily net assets. These fees are calculated daily and
      paid monthly. The fees received by Legg Mason during any year may be more
      or less than its cost of providing distribution and shareholder services
      for Primary Shares.

          Legg Mason receives a fee from BFDS for assisting it with its transfer
      agent and shareholder servicing functions; for the year ended March 31,
      1998, Legg Mason received from BFDS $17,000, $8,000 and $6,000 for
      performing such services in connection with Maryland Tax-Free,
      Pennsylvania Tax-Free and Tax-Free Intermediate, respectively.

          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 received. Each Fund's Plan complies with those rules.

          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.

          The President and Treasurer of the Trust are employed by Legg Mason.

THE FUNDS' CUSTODIAN AND TRANSFER AGENT
          State Street Bank and Trust Company, P.O. Box 1713, Boston,
      Massachusetts 02105, is custodian for the securities and cash of the
      Funds. Boston Financial Data Services, P.O. Box 953, Boston, Massachusetts
      02103, is the transfer agent for Fund shares and dividend-disbursing agent
      for the Funds.

DESCRIPTION OF THE TRUST AND ITS SHARES
          The Trust was established as a Massachusetts business trust under a
      Declaration of Trust dated November 21, 1990. The Declaration of Trust
      authorizes the Trust to issue an unlimited number of shares and to create
      additional series, each of
                                                                              23

<PAGE>

      which may issue separate classes of shares. Three series of the Trust
      currently are being offered.

          Each series of the Trust currently offers 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 and sales charges, which may
      affect performance.

          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 Trustees of the Trust 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
      trustees, approval of an advisory contract, and approval of a plan of
      distribution pursuant to Rule 12b-1). The Trust 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.

     EXPENSES

          The purpose of the following table 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 Class of Pennsylvania Tax-Free for the
      period March 10, 1998 (commencement of operations) to March 31, 1998 and
      are based on estimated expenses for the initial period of operations of
      the Navigator Classes of Maryland Tax-Free and Tax-Free Intermediate.

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

                            MARYLAND   PENNSYLVANIA     TAX-FREE
                            TAX-FREE     TAX-FREE     INTERMEDIATE

                            ======================================

    ----------
    (A) After fee waivers. Pursuant to a voluntary expense limitation, the
        Adviser has agreed to waive management fees such that total operating
        expenses relating to Navigator Shares (exclusive of taxes, interest,
        brokerage fees and extraordinary expenses) will not exceed annual rates
        of 0.45% of average daily net assets of each Fund until July 31, 1999 or
        until Maryland Tax-Free's net assets reach $200 million, whichever
        occurs first; or until Pennsylvania Tax-Free's net assets reach $125
        million, whichever occurs first; or until Tax-Free Intermediate's net
        assets reach $100 million, whichever occurs first. In the absence of
        such waivers, the management fee, other expenses and total operating
        expenses relating to Navigator Shares would be as follows: for Maryland
        Tax-Free, 0.55%, 0.13% and 0.68% of average net assets; for Pennsylvania
        Tax-Free, 0.55%, 0.19% and 0.74% of average net assets; and for Tax-Free
        Intermediate, 0.55%, 0.26% and 0.81% of average net assets.
    (B) Each Fund has entered into an arrangement with its custodian whereby
        uninvested cash balances generate credits used to reduce custodian
        expenses. Other expenses and total operating expenses net of this
        reduction were the same for each Fund.

          For further information concerning the expenses of each Fund, please
      see "The Funds' Management and Investment Adviser," page 16.

      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) redemption at the end of each time
      period. The Funds charge no redemption fees of any kind.

                                       1       3       5      10
                                      YEAR   YEARS   YEARS   YEARS
                                      ----------------------------
      Maryland Tax-Free                $5     $14     $25     $57
      Pennsylvania Tax-Free            $5     $14     $25     $57
      Tax-Free Intermediate            $5     $14     $25     $57

          This example assumes that all dividends and capital gain distributions
      are reinvested and that the percentage amounts listed under Annual Fund
      Operating Expenses remain the same over the time periods shown.

          If the waivers are not extended beyond July 31, 1999, the expense
      figures in the examples will be higher. The above table and 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 TABLE 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 attributable to
      Navigator 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 Navigator Shares incur variable expenses, such as transfer
      agency costs, and whether the Adviser waives all or a portion of a Fund's
      expenses.
                                                                               3

     PERFORMANCE INFORMATION

          From time to time each Fund may quote the TOTAL RETURN of a 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 of an investment in the fund, including changes in share
      price and assuming reinvestment of dividends and capital gain
      distributions. 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.
      Average annual returns, which differ from actual year-by-year results,
      tend to smooth out variations in a fund's returns.

          As of the date of this Prospectus, Navigator Shares of Maryland
      Tax-Free and Tax-Free Intermediate have no performance record and
      Navigator Shares of Pennsylvania Tax-Free have only a brief performance
      history. Because Navigator Shares have lower total expenses, they will
      generally have a higher return than Primary Shares. Total returns of
      Primary Shares as of March 31, 1998 were as follows:

          Each Fund also may advertise its yield or tax equivalent yield. Yield
      reflects investment income net of expenses over a 30-day (or one-month)
      period on a Fund share, expressed as an annualized percentage of the
      maximum offering price per share at the end of the period. Tax equivalent
      yield shows the taxable yield an investor would have to earn before taxes
      to equal the Fund's tax-exempt yield. A tax equivalent yield is calculated
      by dividing a Fund's tax-exempt yield by the result of one minus a stated
      federal, state and local income tax rate. 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.

          Total return and yield information reflect past performance and are
      not predictions or guarantees of future results. Yields and total returns
      of Primary Shares of the Funds would be lower if the Adviser and Legg
      Mason had not waived a portion of the fees during the fiscal years 1992
      through 1998. Investment return and share price will fluctuate, and the
      value of your shares, when redeemed, may be worth more or less than their
      original cost.

          Further information about each Fund's performance is contained in the
      combined 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.

WHO SHOULD INVEST

          Maryland Tax-Free is designed for longer-term investors who are able
      to benefit from income exempt from federal and Maryland state and local
      income taxes. Pennsylvania Tax-Free is designed for longer-term investors
      who are able to benefit from income exempt from federal income tax and
      Pennsylvania personal income tax. Tax-Free Intermediate is designed for
      intermediate-term investors who are able to benefit from income exempt
      from federal income tax. The value of Navigator Shares can generally be
      expected to fluctuate inversely with changes in interest rates and,
      because of the potential negative impact of rising interest rates and
      other risks, the Funds would not be appropriate for investors whose
      primary goal is stability of principal. Each Fund is not intended to be a
      balanced investment program. Each Fund is not an appropriate investment
      for "substantial users" of certain facilities financed by industrial
      development or private activity bonds or related persons thereof. See
      "Taxes -- Federal Income Tax," page 14.

     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 Trust's Board
      of Trustees without a shareholder vote. There can be no assurance that any
      Fund will achieve its investment objective.

          MARYLAND TAX-FREE'S investment objective is to earn a high level of
      current income exempt from federal and Maryland state and local income
      taxes, consistent with prudent investment risk and preservation of
      capital. The Fund seeks to achieve its investment objective by investing
      primarily in debt instruments issued by or on behalf of the State of
      Maryland, its political subdivisions, municipalities, agencies,
      instrumentalities or public authorities, the interest on which, in the
      opinion of counsel to the issuers of those instruments, is exempt from
      federal and Maryland state and local income taxes. As a fundamental
      policy, under normal circumstances, the Fund will maintain at least 80% of
      its total assets in Maryland municipal obligations, exclusive of any such
      obligations the interest on which is a tax preference item for purposes of
      the federal alternative minimum tax ("Tax Preference Item"). See
      "Temporary Investments," page 7.

          PENNSYLVANIA TAX-FREE'S investment objective is to earn a high level
      of current income exempt from federal income tax and Pennsylvania personal
      income tax, consistent with prudent investment risk and preservation of
      capital. The Fund seeks to achieve its investment objective by investing
      primarily in debt instruments issued by or on behalf of the Commonwealth
      of Pennsylvania, its political subdivisions, municipalities, agencies,
      instrumentalities or public authorities, the interest on which, in the
      opinion of counsel to the issuers of those instruments, is exempt from
      federal income tax and Pennsylvania personal income tax. As a fundamental
      policy, under normal circumstances, the Fund will maintain at least 80% of
      its total assets in Pennsylvania municipal obligations, exclusive of any
      such obligations the interest on which is a Tax Preference Item. See
      "Temporary Investments" page 7.

          TAX-FREE INTERMEDIATE'S investment objective is to earn a high level
      of current income exempt from federal income tax, consistent with prudent
      investment risk. The Fund seeks to achieve its investment objective by
      investing primarily in debt instruments issued by or on behalf of states,
      territories and possessions of the United States, the District of Columbia
      and their respective authorities, agencies, instrumentalities and
      political subdivisions, the interest on which, in the opinion of counsel
      to the issuers of those instruments, is exempt from federal income tax
      ("municipal obligations"), while maintaining an average dollar-weighted
      maturity of between 2 and 10 years. As a fundamental policy, under normal
      circumstances, the Fund will maintain at least 80% of its total assets in
      municipal obligations exclusive of any such obligations the interest on
      which is a Tax Preference Item. See "Temporary Investments," page 7.

          Each Fund invests in securities that, in the opinion of the Adviser,
      present acceptable credit risks and that, at the time of purchase, are
      rated:

          "Baa" or higher by Moody's, "BBB" or higher by S&P or Fitch in the
      case of bonds;

          "MIG-1" by Moody's, "SP-1" or higher by S&P or "F-1" or higher by
      Fitch in the case of notes;

          "P1" by Moody's, "A1" by S&P or "F-1" or higher by Fitch in the case
      of commercial paper; and

          "VMIG-1" by Moody's in the case of variable rate demand notes.

          Each Fund also invests in securities unrated by any of the above
      services which are deemed by the Adviser to be of comparable quality.

          The bond ratings noted above are considered "investment grade" by the
      respective rating agencies. A rating of a municipal obligation represents
      the rating agency's opinion regarding its quality and is not a guarantee
      of quality. Moody's considers bonds rated in its fourth highest category
      (i.e., Baa) 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 higher rated bonds. In the event the rating
      on an issue held in a Fund's portfolio is changed by Moody's, S&P or
      Fitch, such change will be considered by the Adviser in its evaluation of
      the overall investment merits of that security. If, as a result of any
      downgradings by Moody's, S&P or Fitch or, for unrated securities, any
      determinations by the Adviser that securities are no longer of comparable
      quality to investment grade securities, more than 5% of a Fund's total
      assets are represented by securities rated below investment grade or the
      equivalent, the Adviser will, as soon as practicable consistent

6

<PAGE>

      with achieving an orderly disposition of the securities, sell such
      holdings until they represent 5% or less of the Fund's total assets. A
      discussion of the ratings outlined above is included in the Statement of
      Additional Information.

          In addition to the agency ratings, there are other criteria which will
      be used by the Adviser in selecting securities for a portfolio.
      Consideration will be given to the maturity and duration of each bond as
      well as its effect on the overall average maturity and duration of the
      portfolio. Analysis of the current and historical yield spreads is done to
      determine the relative value in any bond considered for purchase. The
      coupon level and call features also figure in the decision on the relative
      merits of an investment. Consideration is also given to the type of
      bond -- whether it is a general obligation or a revenue bond. In addition
      to this examination of bond characteristics, significant effort is devoted
      to analysis of the creditworthiness of the bond issuer at the time of
      purchase and on an ongoing basis.

          Each Fund is permitted to invest in municipal securities of any
      maturity. The maturities of a Fund's portfolio securities will reflect the
      Adviser's judgment concerning current and future market conditions as well
      as other factors, such as the Fund's liquidity needs. Under normal
      circumstances, the dollar-weighted average maturities of Maryland
      Tax-Free's and Pennsylvania Tax-Free's portfolios are expected to be
      between 12 and 24 years and the dollar-weighted average maturity of
      Tax-Free Intermediate's portfolio is expected to be between 2 and 10
      years.

          Each Fund does not expect its portfolio turnover rate to exceed 90%
      per year.

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. Other public purposes for which
      municipal obligations may be issued include the refunding of outstanding
      obligations, the obtaining of funds for general operating expenses and the
      making of loans to other public institutions and facilities. In addition,
      certain types of industrial development bonds ("IDBs") and private
      activity bonds ("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. Interest on certain
      tax-exempt PABs will constitute a Tax Preference Item. Accordingly, under
      normal circumstances, each Fund's investment in obligations, the interest
      on which is such an item, including PABs, will be limited to a maximum of
      20% of its total assets.

          Municipal obligations also include short-term tax anticipation notes,
      bond anticipation notes, revenue anticipation notes and other forms of
      short-term debt obligations. Such notes may be issued with a short-term
      maturity in anticipation of the receipt of tax payments, the proceeds of
      bond placements or other revenues.

          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. "Certificates of Participation" are participations in municipal
      lease obligations or installment sales contracts. Each certificate
      represents a proportionate interest in or right to the lease purchase
      payments made.

          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. IDBs and PABs are usually revenue
      bonds and are not payable from the unrestricted revenues of the issuer.
      The credit quality of IDBs and PABs is usually directly related to the
      credit standing of the corporate user of the facilities.

TEMPORARY INVESTMENTS

          During unusual market conditions, including if, in the Adviser's
      opinion, there are insufficient suitable Maryland municipal obligations
      (with respect to Maryland Tax-Free), Pennsylvania municipal obligations
      (with respect to Pennsylvania Tax-Free) or municipal obligations (with
      respect to Tax-Free Intermediate) available that pay interest that is not
      a Tax Preference Item, a Fund temporarily may invest more than 20% of its
      total assets in municipal obligations the interest on which is exempt from
      federal income tax but is such an item (with respect to Tax-Free
      Intermediate) and/or is subject to Maryland state and local income taxes
      (with respect to Maryland Tax-Free) and/or is subject to Pennsylvania
      personal income tax (with respect to Pennsylvania Tax-Free). Each
                                                                               7

<PAGE>

      Fund expects that under normal circumstances it will maintain needed
      liquidity through the purchase of short-term municipal securities.
      However, for liquidity purposes, or pending the investment of the proceeds
      of the sale of shares, a Fund temporarily may invest in taxable short-term
      investments consisting of: obligations of the U.S. Government, its
      agencies and instrumentalities; certificates of deposit and bankers'
      acceptances of U.S. domestic banks with assets of one billion dollars or
      more; commercial paper or other corporate notes of high quality; and any
      of such items subject to short-term repurchase agreements. Each Fund may
      invest without limit in such instruments for temporary, defensive
      purposes, when in the Adviser's opinion, no suitable municipal securities
      are available. No more than 10% of a Fund's net assets will be invested in
      repurchase agreements maturing in more than seven days and other illiquid
      securities. Interest earned from such taxable investments will be taxable
      to investors as ordinary income when distributed to them.

          As a fundamental policy, each Fund may borrow money solely for
      temporary purposes from banks or by engaging in reverse repurchase
      agreements in an amount up to 10% of the value of its total assets;
      however, borrowings by a Fund in excess of 5% of the value of its total
      assets may be only from banks.

YIELD AND RISK FACTORS

      Yield

          The yield of a municipal obligation is dependent on a variety of
      factors, including general municipal securities market conditions, general
      fixed-income market conditions, the financial condition of the issuer, the
      size of the particular offering, the maturity of the obligation, the
      credit quality and rating of the issue and expectations regarding changes
      in income tax rates.

      Interest Rate Risk

          If general market interest rates increase, the prices of municipal
      obligations ordinarily will decrease. In a market of decreasing interest
      rates, the opposite generally will be true. Although longer-term bonds
      generally offer higher yields than shorter-term bonds, their prices are
      more sensitive to changes in interest rates than bonds with shorter
      maturities. Under normal circumstances, the dollar-weighted average
      maturities of Maryland Tax-Free's and Pennsylvania Tax-Free's portfolios
      are expected to be 12-24 years and the dollar-weighted average maturity of
      Tax-Free Intermediate's portfolio is expected to be 2-10 years.

      For Maryland Tax-Free:

          Changes in economic conditions in, or governmental policies of, the
      state of Maryland could have a significant impact on the performance of
      the Fund. For example, services (including mining), wholesale and retail
      trade, government, and manufacturing (primarily printing and publishing,
      food and kindred products, instruments and related products, electronic
      equipment, industrial machinery and transportation equipment) are the
      leading areas of employment in the State of Maryland. In contrast to the
      nation as a whole, more people in Maryland are employed in government than
      in manufacturing. The relatively high concentration of governmental
      employment in Maryland makes the state potentially vulnerable to any
      decreases in federal, including military, and state governmental spending.

          The Fund may invest in certain municipal obligations with unique
      risks. These include, but are not limited to, securities issued by
      hospitals and other healthcare providers. The hospital industry throughout
      the nation has been subjected to pressure to reduce expenses and to limit
      lengths of stay. That pressure may adversely affect the financial health
      of some hospitals.

          An expanded discussion of certain investment considerations relating
      to debt obligations of Maryland and its political subdivisions is
      contained in the Statement of Additional Information.

      For Pennsylvania Tax-Free:

          Changes in economic conditions in, or governmental policies of, the
      Commonwealth of Pennsylvania could have a significant impact on the
      performance of the Fund. For example, Pennsylvania's continued dependence
      on manufacturing, mining and steel has made Pennsylvania vulnerable to
      cyclical industry fluctuations, foreign imports and environmental
      concerns. However, growth in the service and trade sectors has helped
      diversify Pennsylvania's economy and reduce its unemployment rate below
      the national average. Changes in local economic conditions or local
      governmental policies within Pennsylvania, which can vary substantially by
      region, could also have a significant impact on the performance of
      municipal obligations held by the Fund. The City of Philadelphia, for
      example, experienced severe financial problems which impaired its ability
      to borrow money and adversely affected the ratings of its obligations and
      their marketability. While the Fund may invest in obligations that are
      secured by obligors other than Pennsylvania or its political subdivisions
      (such as hospitals, universities, corporate obligors and corporate credit
      and liquidity

8

<PAGE>

      providers) and obligations limited to specific revenue pledges (such as
      sewer authority bonds), the creditworthiness of these obligors may be
      partly dependent on the creditworthiness of Pennsylvania or its municipal
      authorities.

          An expanded discussion of certain investment considerations relating
      to debt obligations of Pennsylvania and its political subdivisions is
      contained in the Statement of Additional Information.

      Concentration

          Each Fund may invest 25% or more of its total assets in a particular
      segment of the municipal securities market, such as hospital revenue
      bonds, housing agency bonds, IDBs or airport bonds, or in securities the
      interest on which is paid from revenues of a similar type of project. In
      such circumstances, economic, business, political or other changes
      affecting one issue of bonds (such as proposed legislation affecting
      healthcare or the financing of a project, shortages or price increases of
      needed materials, or declining markets or needs for the projects) would
      most likely affect other bonds in the same segment, thereby potentially
      increasing market risk. As a result, each Fund is subject to greater risk
      than other funds that do not follow this practice.

      Non-Diversification

          Each Fund has registered as a "non-diversified" investment company.
      Therefore, the percentage of Fund assets invested in any single issuer is
      not limited by the Investment Company Act of 1940, as amended ("1940
      Act"). However, each Fund intends to continue to qualify as a regulated
      investment company ("RIC") under the Internal Revenue Code of 1986, as
      amended ("Code"). To qualify as a RIC, a Fund generally must meet the
      following diversification requirements at the close of each quarter of its
      taxable year: (1) at least 50% of the value of its total assets must
      consist of cash, securities of the U.S. Government and other RICs and
      holdings of other securities, which, with respect to any one issuer, do
      not have a value greater than 5% of the value of the Fund's total assets;
      and (2) no more than 25% of the value of its total assets may be invested
      in the securities of a single issuer. For these purposes, the term
      "issuer" does not include the U.S. Government or other RICs. To the extent
      that a Fund's assets are invested in the obligations of a limited number
      of issuers, the value of that Fund's shares will be more susceptible to
      any single economic, political or regulatory occurrence affecting one or
      more of those issuers than the shares of a diversified investment company
      would be.

      Other Risks

          Current efforts to restructure the federal budget and the relationship
      between the federal government and state and local governments may impact
      the financing of some issuers of municipal securities. Some states and
      localities at times experience substantial deficits and may find it
      difficult for political or economic reasons to increase taxes. Some local
      jurisdictions have invested heavily in derivative instruments and may now
      hold portfolios of uncertain valuation. Each of these factors may affect
      the ability of an issuer of municipal securities to meet its obligations.
      Efforts by Congress to restructure the federal income tax system could
      adversely affect the value of municipal securities.

INVESTMENT TECHNIQUES

          Each Fund may employ the investment techniques described below, among
      others. Use of certain of these techniques may give rise to taxable
      income.

      When-Issued Securities

          Each Fund may enter into commitments to purchase municipal obligations
      or other securities on a when-issued basis. Such securities are often the
      most efficiently priced and have the best liquidity in the bond market.
      When a Fund purchases securities on a when-issued basis, it assumes the
      risks of ownership, including the risk of price fluctuation, at the time
      of purchase, not at the time of receipt. However, a Fund does not have to
      pay for the obligations until they are delivered to it, normally 15 to 45
      days later. To meet its payment obligation, a Fund will establish a
      segregated account with its custodian and maintain cash or appropriate
      liquid obligations in an amount at least equal to the payment that will be
      due. Use of this practice would have a leveraging effect on a Fund. Each
      Fund does not expect that its commitment to purchase when-issued
      securities will at any time exceed, in the aggregate, 25% of total assets.

      Callable Bonds

          Callable municipal bonds are municipal bonds which carry a provision
      permitting the issuer to redeem the bonds prior to their maturity dates at
      a specified price which typically reflects a premium over the bonds'
      original issue price. If the proceeds of a bond owned by a Fund called
      under circumstances favorable to the issuer are reinvested, the
                                                                               9

<PAGE>

      result may be a lower overall yield on such proceeds upon reinvestment
      because of lower prevailing interest rates. If the purchase price of such
      bonds included a premium related to the appreciated value of the bonds,
      some or all of that premium may not be recovered by bondholders, such as
      the Funds, depending on the price at which such bonds were redeemed.

          Each callable bond is "marked-to-market" daily based on the bond's
      call date so that the call of some or all of a Fund's callable bonds is
      not expected to have a material impact on that Fund's net asset value. In
      light of the previously described pricing policies and because each Fund
      follows certain amortization procedures required by the Internal Revenue
      Service, each Fund does not expect to suffer any material adverse impact
      in connection with a call of bonds purchased at a premium. Notwithstanding
      such policies, however, as with any investment strategy, there is no
      guarantee that a call may not have a more substantial impact than
      anticipated.

      Stand-By Commitments

          Each Fund may acquire "stand-by commitments" with respect to its
      investments in municipal obligations. A stand-by commitment is a put (that
      is, the right to sell the underlying security within a specified period of
      time at a specified exercise price that may be sold, transferred or
      assigned only with the underlying security) that entitles the Fund to
      same-day settlement. Under a stand-by commitment, a broker, dealer or bank
      agrees to purchase, at the Fund's option, specified municipal obligations
      at amortized cost plus accrued interest. The total amount paid for
      outstanding stand-by commitments held by a Fund will not exceed 25% of
      that Fund's total assets calculated immediately after each stand-by
      commitment is acquired.

      Securities Lending, Zero Coupon and Deferred Interest Bonds
          Each Fund may engage in securities lending and may invest in zero
      coupon and deferred interest bonds. However, each Fund does not currently
      intend to loan securities with a value exceeding 5% of its net assets or
      to invest more than 5% of its net assets in zero coupon and deferred
      interest bonds. Any income from securities lending would be taxable when
      distributed to shareholders. For further information concerning securities
      lending, zero coupon and deferred interest bonds, see the Statement of
      Additional Information.

      Variable Rate and Floating Rate Obligations
          Each Fund may invest in variable rate municipal obligations and notes.
      Variable rate obligations have an interest rate that is adjusted
      periodically based upon market conditions.

          Each Fund may also invest in floating rate and variable rate demand
      notes. Demand notes provide that the holder may demand payment of the note
      at its par value plus accrued interest. These notes may be supported by an
      unconditional bank letter of credit guaranteeing payment of the principal
      or both the principal and accrued interest. Because each Fund invests in
      such securities backed by banks and other financial institutions, changes
      in the credit quality of these institutions could cause losses to a Fund.
      Floating rate demand notes have an interest rate related to a known
      lending rate, such as the prime rate, and are automatically adjusted when
      such known rate changes. Such securities often react to changes in market
      interest rates in a manner similar to shorter-term securities that mature
      at the time of the next interest rate reset for the variable or floating
      rate instrument. In calculating its dollar-weighted average maturity, a
      Fund may determine the maturity of a variable or floating rate note
      according to the interest rate reset date, or the date principal can be
      recovered on demand, rather than the date of ultimate maturity.

      Futures and Option Strategies
          To protect against the effect of adverse changes in interest rates,
      each Fund may purchase and sell interest rate futures contracts and
      options on securities indexes, and may purchase put options on interest
      rate futures contracts (practices known as "hedging"). A Fund may purchase
      put options on interest rate futures contracts or sell interest rate
      futures contracts (that is, enter into a futures contract to sell the
      underlying security) to attempt to reduce the risk of fluctuations in its
      share value. A Fund may purchase an interest rate futures contract (that
      is, enter into a futures contract to purchase the underlying security) to
      attempt to establish more definitely the return on securities the Fund
      intends to purchase. The Funds may not use these instruments for
      speculation or leverage. In addition, a Fund's ability to use these
      strategies may be limited by market conditions, regulatory limits and tax
      considerations. Any gains from futures and options transactions would be
      taxable.

          The success of a Fund's strategies in reducing risks depends on many
      factors, the most significant of which is the Adviser's ability to predict
      market interest rate changes correctly, which differs from its ability to
      select portfolio securities. In addition, a hedge could be unsuccessful if
      the changes in the value of a Fund's futures contract

10

<PAGE>

      or option positions do not correlate to the changes in the value of its
      investments. It is also possible that a Fund may be unable to purchase or
      sell a portfolio security at a time that otherwise would be favorable for
      it to do so, or that a Fund may need to sell a portfolio security at a
      disadvantageous time, due to the need for the Fund to maintain "cover" or
      to segregate securities in connection with hedging transactions. Because
      the markets for futures and options are not always liquid, a Fund may be
      unable to close out or liquidate its hedged position and may be locked in
      during a market decline. The Adviser attempts to minimize the possible
      negative effects of these factors through careful selection and monitoring
      of each Fund's futures and options positions. The Adviser is of the
      opinion that a Fund's investment in futures transactions will not have a
      material adverse effect on that Fund's liquidity or ability to honor
      redemptions.

          The purchase and sale of options and futures contracts involve risks
      different from those involved with direct investments in securities, and
      also require different skills from the Adviser in managing the portfolios.
      While utilization of options, futures contracts and similar instruments
      may be advantageous to a Fund, if the Adviser is not successful in
      employing such instruments in managing a Fund's investments or in
      predicting interest rate changes, that Fund's performance will be worse
      than if the Fund did not use such instruments. In addition, a Fund will
      pay commissions and other costs in connection with such investments, which
      may increase that Fund's expenses and reduce its yield. A more complete
      discussion of the possible risks involved in transactions in options and
      futures contracts is contained in the Statement of Additional Information.

          Each Fund's current policy is to limit options and futures
      transactions to those described above. Each Fund currently does not intend
      to purchase put and call options having a value in excess of 5% of its
      total assets.

INVESTMENT LIMITATIONS

          Each Fund has adopted certain fundamental limitations that, like its
      investment objective, can be changed only by the vote of a majority of the
      outstanding voting securities of that Fund. For these purposes, 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 in person or by proxy. These investment limitations are set
      forth under "Additional Information About Investment Limitations and
      Policies" in the Statement of Additional Information. Fund policies,
      unless described as fundamental, can be changed by the Board of Trustees.

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
      Institutional Clients. 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 a 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 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
                                                                              11

<PAGE>

      Exchange is open. See "How Net Asset Value is Determined" on page 13.

          Certain institutions that have agreements with Legg Mason or the Funds
      may be authorized to accept purchase and redemption orders on their
      behalf. In that case, a Fund will be deemed to have received your purchase
      or redemption order when the authorized institution accepts the order, and
      your order will receive the next price calculated after the order has been
      accepted by the institution. You should consult with your institution to
      determine the time by which it must receive your order for you to purchase
      or redeem Fund shares at that day's price. It is the institution's
      responsibility to transmit your order to the Fund in a timely fashion.

          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 advisor 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. See above for information on pricing of
      redemptions made through certain institutions having agreements with Legg
      Mason or the Funds.

          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, that 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.)

          Each Fund will not be responsible for the authenticity of redemption
      instructions received by telephone, provided it follows reasonable
      procedures to identify the caller. Each Fund may request identifying
      information from callers or employ identification numbers. Each Fund may
      be 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.

12

<PAGE>

          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, no Fund will 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 investor 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. Each Institutional Client may establish its own minimum
      account size for investors using its services.

HOW SHAREHOLDER ACCOUNTS ARE MAINTAINED

          A shareholder account is established automatically for each investor.
      Any shares the investor purchases or receives as a dividend or other
      distribution will be credited directly to the account at the time of
      purchase or receipt. Shares may not be held in, or transferred to, an
      account with any entity that does not have an agreement with Legg Mason or
      Fairfield. 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 based upon appraisals received from an independent 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. Debt securities with
      remaining maturities of 60 days or less are valued at amortized cost,
      unless conditions otherwise indicate. Other securities are valued at fair
      value as determined by, or under the supervision of, the Board of Trustees
      of the Trust.

DIVIDENDS AND OTHER DISTRIBUTIONS

          Dividends from net investment income of each Fund are declared daily
      and paid monthly. Shareholders begin to earn dividends on their Navigator
      Shares as of the settlement date, which is normally the third business day
      after their orders are placed with their Financial Advisor or Service
      Provider. Dividends from any 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), if any, 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.

          Navigator Shares held by qualified retirement plans generally receive
      dividends and other distributions in additional shares. Other shareholders
      may elect to:

          1. Receive both dividends and capital gain distributions in Navigator
      Shares of the distributing Fund;

          2. Receive dividends in cash and capital gain distributions in
      Navigator Shares of the distributing Fund;

          3. Receive dividends in Navigator Shares of the distributing Fund and
      capital gain distributions in cash; or

          4. Receive both dividends and capital gain distributions in cash.

          If a shareholder has elected to receive dividends and/or capital gain
      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 capital gain distributions reinvested in
      additional Navigator Shares. No interest will accrue on amounts
      represented by uncashed distribution or redemption checks.

          In certain cases, shareholders may reinvest dividends and capital gain
      distributions in shares
                                                                              13

<PAGE>

      of another Navigator fund. Please contact a financial advisor for
      additional information about this option.

          If no election is made, both dividends and capital gain 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 capital gain 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. Customers of
      Institutional Clients should confer with the Institutional Client
      regarding any change in the election. An election must be received by Legg
      Mason at least 10 days before the record date in order to be effective for
      dividends and capital gain distributions paid to shareholders as of that
      date.

TAXES

      Federal Income Tax

          Each Fund intends to continue to qualify for treatment as a RIC under
      the Code so that it will be relieved of federal income tax on that part of
      its investment company taxable income (generally, taxable net investment
      income and any net short-term capital gain) and net capital gain that it
      distributes to its shareholders. If a Fund so qualifies and, at the close
      of each quarter of its taxable year, at least 50% of the value of its
      total assets consists of certain obligations the interest on which is
      excludable from gross income under Section 103(a) of the Code, that Fund
      may pay "exempt-interest" dividends to its shareholders. Those dividends
      constitute the portion of the aggregate dividends (excluding capital gain
      distributions), as designated by the Fund, equal to the excess of the
      Fund's excludable interest over certain amounts disallowed as deductions.
      Exempt-interest dividends are excludable from a shareholder's gross
      income; however, the amount of such dividends must be reported on the
      recipient's federal income tax return.

          If and to the extent a Fund receives interest on certain PABs, a
      proportionate part of the exempt-interest dividends paid by the Fund will
      be treated as a Tax Preference Item. In addition, exempt-interest
      dividends received by a corporate shareholder may be indirectly subject to
      the federal alternative minimum tax without regard to whether the
      distributing Fund's tax-exempt interest is attributable to PABs.

          To the extent dividends are derived from taxable income from temporary
      investments, from net short-term capital gain or from the use of certain
      investment techniques described in "Investment Objective and Policies,"
      page 6, they are taxable to shareholders as ordinary income (whether paid
      in cash or reinvested in Navigator Shares). No portion of those dividends
      will qualify for the corporate dividends-received deduction. Distributions
      derived from net capital gain, if any, are taxable to shareholders as
      long-term capital gain regardless of the length of time they have held
      their Navigator Shares (and irrespective of whether those distributions
      are paid in cash or reinvested in Navigator Shares). The maximum tax rate
      applicable to a noncorporate taxpayer's net capital gain recognized on
      capital assets held for more than one year is 20% (10% for taxpayers in
      the 15% marginal tax bracket). In the case of a RIC such as the Funds, the
      relevant holding period is determined by how long the Fund has held the
      portfolio security on which the gain was realized, not by how long you
      have held your Fund shares.

          Interest on indebtedness incurred or continued by a shareholder to
      purchase or carry Navigator Shares generally is not deductible. Persons
      who are "substantial users" (or related persons) of facilities financed by
      IDBs or PABs should consult their tax advisers before purchasing shares of
      a Fund because, for users of certain of these facilities, the interest on
      those bonds is not exempt from federal income tax. For these purposes, a
      "substantial user" includes a non-exempt person who regularly uses in
      trade or business a part of a facility financed from the proceeds of IDBs
      or PABs.

          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 any
      other Navigator fund generally will have similar tax consequences. See
      "Shareholder Services -- Exchange Privilege." If Navigator Shares are
      purchased within 30 days before or

14

<PAGE>

      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.

      For Maryland Tax-Free:

      Maryland Taxes

          Distributions paid by Maryland Tax-Free to Maryland residents
      attributable to interest received or capital gains recognized by the Fund
      on Maryland municipal obligations are exempt from Maryland state and local
      income taxes. Distributions attributable to interest received or capital
      gains recognized by the Fund on certain U.S. government obligations also
      are exempt from Maryland state and local income taxes. Distributions
      attributable to the Fund's other income or gains generally are subject to
      these taxes.

          Interest on indebtedness incurred by a shareholder to purchase or
      carry Fund shares generally is not deductible for purposes of either
      Maryland state or local income tax. Fund shares held by an individual are
      not subject to the Maryland personal property tax. Fund shares held by a
      corporation also are not subject to the Maryland personal property tax.
      Dividends paid by the Fund with respect to Maryland municipal obligations
      and profits realized on the sale or exchange of such obligations are not
      subject to the Maryland Franchise Tax imposed on "financial institutions"
      and measured by net earnings.

          In the case of individuals, Maryland imposes an income tax on Tax
      Preference Items. Interest paid on certain PABs is a Tax Preference Item.
      Accordingly, if the Fund holds such bonds, 50% of the interest thereon in
      excess of a threshold amount is subject to Maryland state and local tax.

          Dividends derived from interest on Maryland municipal obligations may
      not be exempt from taxation under the laws of states other than Maryland.

      For Pennsylvania Tax-Free:

      Pennsylvania Taxes

          Individual shareholders of Pennsylvania Tax-Free who are otherwise
      subject to the Pennsylvania personal income tax will not be subject to
      that tax on distributions by the Fund that are attributable to interest on
      Pennsylvania municipal obligations. Distributions attributable to most
      other sources, including gains, will not be exempt from Pennsylvania
      personal income tax.

          Navigator Shares that are held by individual shareholders who are
      Pennsylvania residents will be exempt from the Pennsylvania county
      personal property tax to the extent that the Fund's portfolio consists of
      Pennsylvania municipal obligations on the annual assessment date.
      Nonresidents of Pennsylvania are not subject to this tax. Corporations are
      not subject to any of these personal property taxes. For shareholders who
      are residents of the City of Philadelphia, distributions of interest
      derived from Pennsylvania municipal obligations are not taxable for
      purposes of the Philadelphia School District investment net income tax,
      provided that the Fund reports to its shareholders the percentage of
      Pennsylvania municipal obligations held by it for the year. The Fund will
      report such percentage to its shareholders.

          Distributions of interest, but not gains, realized on Pennsylvania
      municipal obligations are not subject to the Pennsylvania corporate net
      income tax. The Pennsylvania Department of Revenue also takes the position
      that shares of funds similar to the Fund are not considered exempt assets
      of a corporation for the purposes of determining its capital stock value
      subject to Pennsylvania capital stock and franchise taxes.

          Dividends derived from interest on Pennsylvania municipal obligations
      may not be exempt from taxation under the laws of states other than
      Pennsylvania.

      General

          Shareholders receive information after the close of each year
      concerning the tax status of all dividends and capital gain distributions
      from their Fund(s).

          The foregoing is only a summary of some of the important federal,
      Maryland, Pennsylvania and certain local income tax considerations
      generally affecting the Funds and their shareholders; see the Statement of
      Additional Information for a further discussion. In addition to those
      considerations, which are applicable to any investment in the Funds, there
      may be other federal, state or local tax considerations applicable to a
      particular investor. 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. In addition, Legg Mason clients will
      receive a monthly statement 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.
                                                                              15

<PAGE>

          Confirmations for each purchase and redemption transaction (except a
      reinvestment of dividends or capital gain 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 its 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 a
      corresponding class of shares of any of the Legg Mason funds, including
      the Legg Mason Cash Reserve Trust, provided the shares to be acquired are
      eligible for sale under applicable state securities laws.

          Investments by exchange into 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 11. 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 its exchange
      privilege upon 60 days' notice to shareholders. Some Institutional Clients
      may not offer all of the Navigator funds for exchange.

THE FUNDS' MANAGEMENT AND INVESTMENT ADVISER

BOARD OF TRUSTEES

          The business and affairs of each Fund are managed under the direction
      of the Board of Trustees of the Trust.

ADVISORY AGREEMENTS

          Pursuant to separate advisory agreements with each Fund (each an
      "Advisory Agreement"), which were approved by the Trust's Board of
      Trustees, the Adviser, a wholly owned subsidiary of Legg Mason, Inc. (a
      financial services holding company), serves as each Fund's investment
      adviser. The Adviser acts as the portfolio manager for each Fund and is
      responsible for the actual investment management of the Funds, including
      the responsibility for making investment decisions and placing orders to
      buy, sell or hold a particular security. Each Fund pays the Adviser,
      pursuant to the Advisory Agreement, an advisory fee equal to an annual
      rate of 0.55% of each Fund's average daily net assets attributable to
      Navigator Shares. Because of fee waivers (see below), the Funds paid
      advisory fees for the fiscal year ended March 31, 1998 as follows:

      <TABLE>
      <S><C>
      Maryland Tax-Free                          0.32%
      Pennsylvania Tax-Free                      0.26%
      Tax-Free Intermediate                      0.19%
      </TABLE>

FEE WAIVERS

          The Adviser has agreed to waive advisory fees in any month to the
      extent a Fund's expenses related to Navigator Shares (exclusive of taxes,
      interest, brokerage and extraordinary expenses) during that month exceed
      an annual rate of 0.45% of that Fund's average daily net assets
      attributable to Navigator Shares.

          This waiver expires on July 31, 1999, or when a Fund's assets reach
      the following levels:

      <TABLE>
      <S><C>
      Maryland Tax-Free                    $200 million
      Pennsylvania Tax-Free                $125 million
      Tax-Free Intermediate                $100 million
      </TABLE>

          These agreements are voluntary and may be terminated by the Adviser at
      any time. Each Fund pays all its other expenses which are not assumed by
      the Adviser.

NAVIGATOR SHARES EXPENSE RATIOS

          For the fiscal year ended March 31, 1998, the ratio of each Fund's
      expenses to its average net assets (after application of any fee waivers)
      was:

      <TABLE>
      <S><C>
      Maryland Tax-Free                          0.45%

      Tax-Free Intermediate                      0.45%
      </TABLE>

ADVISER

          The Adviser acts as adviser to private accounts and investment company
      portfolios with a value as of June 30, 1998 of approximately $3 billion.
      The Adviser's address is 100 Light Street, Baltimore, Maryland 21202.

ADMINISTRATION AGREEMENT

          Pursuant to an agreement with the Adviser ("Administration
      Agreement"), which was approved by the Trust's Board of Trustees, LMFA
      serves as the Trust's administrator. LMFA manages the affairs of the Trust
      and provides the Trust with office facilities and personnel reasonably
      necessary for the operation of the Trust. The Adviser pays LMFA, pursuant
      to the Administration Agreement, a fee equal to an annual rate of 0.05% of
      each Fund's average daily net assets.

          LMFA acts as investment adviser or manager to eighteen investment
      company portfolios and to private accounts. Aggregate assets under
      management totaled approximately $12.2 billion as of June 30, 1998.

YEAR 2000

          Like other mutual funds, financial and business organizations around
      the world, the Trust could be adversely affected if the computer systems
      used by its investment adviser 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." The
      Adviser is taking steps that it believes are reasonably designed to
      address the Year 2000 Problem with respect to the computer systems that it
      uses and to obtain assurances that comparable steps are being taken by the
      Trust's 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.

PORTFOLIO MANAGEMENT

          Victoria M. Schwatka has been primarily responsible for the day-to-day
      management of each Fund since its inception. Mrs. Schwatka is a portfolio
      manager and Senior Vice-President of Legg Mason's Fixed Income Group. Mrs.
      Schwatka has been employed by Legg Mason since June, 1986.

          Jane E. Trust became co-manager of the Trust on July 31, 1997. Ms.
      Trust has been a Vice President of the Adviser since July 1994, and a
      portfolio manager for Legg Mason's Fixed Income Group since 1991.

THE FUNDS' DISTRIBUTOR

          Legg Mason, a wholly owned subsidiary of Legg Mason, Inc., is the
      distributor of the Funds' shares pursuant to a separate Underwriting
      Agreement with each Fund. Each Underwriting Agreement obligates Legg Mason
      to pay certain expenses in connection with the offering of shares of the
      Funds, 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 periodic reports have been prepared, set in type and mailed to
      existing shareholders at each respective Fund's expense, and for any
      supplementary sales literature and advertising costs. Legg Mason also
      assists BFDS with certain of its duties as transfer agent; for the year
      ended March 31, 1998, Legg Mason received from BFDS $17,000, $8,000 and
      $6,000 for performing such services in connection with Maryland Tax-Free,
      Pennsylvania Tax-Free and Tax-Free Intermediate, respectively.

          Fairfield, a wholly owned subsidiary of Legg Mason, Inc., is a
      registered broker-dealer with principal offices located at 200 Gibraltar
      Road, Horsham, Pennsylvania 19044. Fairfield may sell Navigator Shares
      pursuant to a Dealer Agreement with the Funds' distributor, Legg Mason.
      Legg Mason and LMFA may make payments out of their own assets to Fairfield
      or others to support the distribution of Navigator Shares and shareholder
      servicing.

          The President and Treasurer of the Trust are employed by Legg Mason.

THE FUND'S CUSTODIAN AND TRANSFER AGENT

          State Street Bank and Trust Company, P.O. Box 1713, Boston,
      Massachusetts 02105, is custodian for the securities and cash of the
      Funds. Boston Financial Data Services, P.O. Box 953, Boston, Massachusetts
      02103, is the transfer agent for Fund shares and dividend-disbursing agent
      for the Funds.
                                                                              17

DESCRIPTION OF THE TRUST AND ITS SHARES

          The Trust was established as a Massachusetts business trust under a
      Declaration of Trust dated November 21, 1990. The Declaration of Trust
      authorizes the Trust to issue an unlimited number of shares and to create
      additional series, each of which may issue separate classes of shares.
      Three series of the Trust currently are being offered.

          Each series of the Trust currently offers 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.
      Each Class of Shares may bear certain differing Class-specific expenses
      and sales charges which may affect performance.

          Investors may obtain more information concerning the Primary Class
      from their financial advisor or by calling 1-800-822-5544.

          The Board of Trustees of the Trust 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. A separate vote is taken by a Class of Shares of a Fund if a
      matter affects just that Class of Shares. 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
      trustees, approval of an advisory contract, and approval of a plan of
      distribution pursuant to Rule 12b-1). The Trust 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.

                      THE LEGG MASON TAX-FREE INCOME FUND:
                    Legg Mason Maryland Tax-Free Income Trust
                  Legg Mason Pennsylvania Tax-Free Income Trust
               Legg Mason Tax-Free Intermediate-Term Income Trust

                       PRIMARY SHARES and NAVIGATOR SHARES

                       STATEMENT OF ADDITIONAL INFORMATION
                                  July 31, 1998

         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, each dated July 31, 1998, as appropriate, which have been filed with the
Securities and Exchange Commission ("SEC"). Copies of the Prospectuses are
available without charge from the Funds' distributor, Legg Mason Wood Walker,
Incorporated ("Legg Mason") at (410) 539-0000. This Statement of Additional
Information is not authorized for use unless preceded or accompanied by a
Prospectus.

         The Legg Mason Tax-Free Income Fund ("Trust") is an open-end investment
company which currently has three separate investment series (each a "Fund").

         Legg Mason Maryland Tax-Free Income Trust ("Maryland Tax-Free Fund")
seeks a high level of current income exempt from federal and Maryland state and
local income taxes, consistent with prudent investment risk and preservation of
capital. In attempting to achieve this objective, the Funds' investment adviser,
Legg Mason Capital Management, Inc. ("Adviser"), invests primarily in debt
instruments issued by or on behalf of the state of Maryland, its political
subdivisions, municipalities, agencies, instrumentalities or public authorities,
the interest on which, in the opinion of counsel to the issuers of those
instruments, is exempt from federal and Maryland state and local income taxes
("Maryland municipal obligations") and which are investment grade.

         Legg Mason Pennsylvania Tax-Free Income Trust ("Pennsylvania Tax-Free
Fund") seeks a high level of current income exempt from federal income tax and
Pennsylvania personal income tax, consistent with prudent investment risk and
preservation of capital. In attempting to achieve this objective, the Adviser
invests primarily in debt instruments issued by or on behalf of the Commonwealth
of Pennsylvania, its political subdivisions, municipalities, agencies,
instrumentalities or public authorities, the interest on which, in the opinion
of counsel to the issuers of those instruments, is exempt from federal income
tax and Pennsylvania personal income tax ("Pennsylvania municipal obligations")
and which are investment grade.

         Legg Mason Tax-Free Intermediate-Term Income Trust ("Tax-Free
Intermediate Fund") seeks a high level of current income exempt from federal
income tax, consistent with prudent investment risk. In attempting to achieve
this objective, the Adviser invests primarily in debt instruments issued by or
on behalf of states, territories and possessions of the United States, the
District of Columbia and their respective authorities, agencies,
instrumentalities and political subdivisions, the interest on which, in the
opinion of counsel to the issuers of those instruments, is exempt from federal
income tax ("municipal obligations") and which are investment grade.

         Under normal circumstances, each Fund's investment in obligations the
interest on which is a tax preference item for purposes of the federal
alternative minimum tax ("Tax Preference Item") will be limited to a maximum of
20% of its total assets.

         Shares of Navigator Maryland Tax-Free Fund, Navigator Pennsylvania
Tax-Free Fund and Navigator Tax-Free Intermediate Fund (collectively referred to
as "Navigator Shares") represent interests in the Funds that 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 accounts of the customers with such 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, and to any qualified retirement plan of Legg Mason, Inc. or
of any of its affiliates. The Navigator Class of Shares of each Fund 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 Legg Mason Maryland Tax-Free Fund, Legg
Mason Pennsylvania Tax-Free Fund and Legg Mason Tax-Free Intermediate Fund
(collectively referred to as "Primary Shares") is offered for sale to all other
investors and may be purchased directly by individuals. The front-end sales
charge is currently being waived for all purchases of Primary Shares of each
Fund through July 31, 1999.

         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 Navigator Shares.  The Funds pay management fees to
Legg Mason Capital Management, Inc. Primary Shares pay a 12b-1 distribution
fee, but Navigator Shares pay no distribution fees.  See "The Fund's
Distributor."

                     ADDITIONAL INFORMATION ABOUT INVESTMENT
                            LIMITATIONS AND POLICIES


         In addition to the investment objectives described in the Prospectuses,
each Fund has adopted certain fundamental investment limitations that cannot be
changed except by a vote of the shareholders of that Fund. The following are
each Fund's fundamental investment limitations set forth in their entirety. Each
Fund may not:

         1. Borrow money, except from banks or through reverse repurchase
agreements for temporary purposes in an aggregate amount not to exceed 10% of
the value of the total assets of the Fund; provided that borrowings, including
reverse repurchase agreements, in excess of 5% of such value will be only from
banks (although not a fundamental policy subject to shareholder approval, the
Fund will not purchase securities if borrowings, including reverse repurchase
agreements, exceed 5% of its total assets);

         2. Issue bonds or any other class of securities preferred over shares
of the Fund in respect of the Fund's assets or earnings, provided that the Trust
may issue separate series of shares in accordance with its Declaration of Trust;

         3. Underwrite the securities of other issuers except insofar as the
Fund may be deemed an underwriter under the Securities Act of 1933, as amended,
in disposing of a portfolio security;

         4. Buy or hold any real estate other than municipal bonds secured by
real estate or interests therein;

         5. Purchase or sell any commodities or commodities contracts, except
that the Fund may purchase or sell interest rate futures contracts, options on
securities indexes and options on interest rate futures contracts;

         6. Purchase or sell any oil, gas or mineral exploration or development
programs;

         7. Make loans, except loans of portfolio securities and except to the
extent the purchase of a portion of an issue of publicly distributed notes,
bonds or other evidences of indebtedness, the entry into repurchase agreements,
or deposits with banks and other financial institutions may be considered loans;

         8. 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 interest rate futures contracts and
options on interest rate futures contracts;

         9. 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 futures
contracts and (b) sell short "against the box" (although not a fundamental
policy, the Fund does not intend to make short sales in excess of 5% of its
assets during the coming year);

         10. Invest 25% or more of its total assets in the securities of issuers
in any one industry, provided that this limitation does not apply to (a)
obligations issued or guaranteed by the U.S. government or its agencies or
instrumentalities or repurchase agreements thereon; (b) Pennsylvania municipal
obligations for the Pennsylvania Tax-Free Fund and Maryland municipal
obligations for the Maryland Tax-Free Fund; and (c) municipal obligations for
the Tax-Free Intermediate Fund. For the purpose of this restriction, industrial
development bonds issued by non-governmental users will not be considered
municipal obligations.


                                       3

<PAGE>



         The foregoing investment limitations cannot be changed without 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.

         As a non-fundamental investment limitation (which may be changed by the
vote of the Trust's Board of Trustees without shareholder approval), each Fund
will not invest more than 10% of its net assets in illiquid securities, a term
which means securities that cannot be disposed of within seven days in the
normal course of business at approximately the amount at which the Fund has
valued the securities and includes, among other things, repurchase agreements
maturing in more than seven days.

         If any percentage restriction is adhered to at the time of an
investment or transaction, a later increase or decrease in percentage resulting
from a change in value of portfolio securities or amount of total assets of a
Fund will not be considered a violation of any of the foregoing fundamental or
non-fundamental limitations.

         Unless otherwise specified, the policies and limitations set forth in
this Statement of Additional Information are non-fundamental and can be changed
without a shareholder vote. Each Fund anticipates being as fully invested as
practicable in municipal obligations; however, there may be occasions when, as a
result of maturities of portfolio securities, or sales of a Fund's shares, or in
order to meet anticipated redemption requests, a Fund may hold cash which is not
earning income or make use of repurchase agreements, the income from which would
be taxable.

Municipal Obligations

         The municipal obligations in which each Fund may invest include
municipal leases and participation interests therein. These obligations, which
may take the form of a lease, an installment purchase or a conditional sales
contract, are issued by state and local governments and authorities to acquire
land and a wide variety of equipment and facilities, such as fire and sanitation
vehicles, telecommunications equipment and other capital assets. Rather than
holding such obligations directly, a Fund may purchase a participation interest
in a municipal lease obligation from a bank or other third party. A
participation interest gives a Fund a specified, undivided pro-rata interest in
the total amount of the obligation.

         Municipal lease obligations have risks distinct from those associated
with general obligation or revenue bonds. State constitutions and statutes set
forth requirements that states or municipalities must meet to incur debt. These
may include voter referenda, interest rate limits or public sale requirements.
Leases, installment purchase or conditional sale contracts (which normally
provide for title to the leased asset to pass to the governmental issuer) have
evolved as a means for governmental issuers to acquire property and equipment
without meeting their constitutional and statutory requirements for the issuance
of debt. The debt-issuance limitations are deemed inapplicable because of the
inclusion in many leases and contracts of "non-appropriation" clauses providing
that the governmental user has no obligation to make future payments under the
lease or contract unless money is appropriated for such purpose by the
appropriate legislative body on a yearly or other periodic basis.

         In determining the liquidity of a municipal lease obligation, the
Adviser will distinguish between simple or direct municipal leases and municipal
lease-backed securities, the latter of which may take the form of a lease-backed
revenue bond or other investment structure using a municipal lease-purchase
agreement as its base. While the former may present special liquidity issues,
the latter are based on a well established method of securing payment of a
municipal obligation. A Fund's investment in municipal lease obligations and
participation interests therein will be treated as illiquid unless the Adviser
determines, pursuant to guidelines established by the Board of Trustees, that
the security could be disposed of within seven days in the normal course of
business at approximately the amount at which the Fund has valued the security.


                                       4

<PAGE>


         The municipal obligations in which each Fund may invest also include
zero coupon bonds and deferred interest bonds, although each Fund currently does
not intend to invest more than 5% of the value of its total assets in such
instruments during the coming year. Zero coupon and deferred interest bonds are
debt obligations which are issued at a significant discount from face value.
Like other municipal securities, the price can also reflect a premium or
discount to par reflecting the market's judgment as to the issuer's
creditworthiness, the interest rate or other similar factors. The 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.
While zero coupon bonds do not require the periodic payment of interest,
deferred interest bonds provide for a period of delay before the regular payment
of interest begins. Such instruments benefit the issuer by mitigating its need
for cash to meet debt service, but also require a higher rate of return to
attract investors who are willing to defer receipt of such cash. Such
instruments may experience greater volatility in market value than debt
obligations which make regular payments of interest. Each Fund will accrue
income on such investments for accounting purposes, which is distributable to
shareholders.

         An issuer's obligations under its municipal obligations are subject to
the provisions of bankruptcy, insolvency and other laws affecting the rights and
remedies of creditors, such as the Federal Bankruptcy Code, and laws that may be
enacted by Congress or state legislatures extending the time for payment of
principal or interest, or both, or imposing other constraints upon enforcement
of such obligations. There is also the possibility that as a result of
litigation or other conditions the power or ability of issuers to meet their
obligations for the payment of interest and principal on their municipal
obligations may be materially and adversely affected.

         Opinions relating to the validity of municipal obligations, to the
exemption of interest thereon from federal income tax, Maryland state and local
income taxes and Pennsylvania personal income tax, and to the lack of treatment
of that interest as a Tax Preference Item, respectively, are rendered by counsel
to the issuers at the time of issuance. Neither the Funds nor the Adviser will
independently review the basis for such opinions.

         The United States Supreme Court has held that Congress may subject the
interest on municipal obligations to federal income tax. It can be expected
that, as in the past, proposals will be introduced before Congress for the
purpose of restricting or eliminating the federal income tax exemption for
interest on municipal obligations. Proposals also may be introduced in state
legislatures which could affect the state tax treatment of each Fund's
distributions. If any such proposals were enacted, the availability of municipal
obligations for investment by the Funds and the value of their assets could be
materially and adversely affected. In such event, each Fund would re-evaluate
its investment objective and policies and consider changes in its structure or
possible dissolution.

When-Issued Securities

         Delivery of and payment for when-issued securities normally take place
15 to 45 days after the date of the commitment. Interest rates on when-issued
securities are normally fixed at the time of the commitment. Consequently,
increases in the market rate of interest between the commitment date and
settlement date may result in a market value for the security on the settlement
date that is less than its purchase price.

         With regard to each such commitment, a Fund maintains in a segregated
account with the custodian, commencing on the date of such commitment, cash,
U.S. government securities or other high-quality liquid debt securities equal in
value to the purchase price for the when-issued securities due on the settlement
date. Each Fund only makes when-issued commitments with the intention of
actually acquiring the securities subject thereto, but a Fund may sell these
securities before the settlement date if market conditions warrant. When payment
is due for when-issued securities, a Fund meets its obligations from
then-available cash flow, from the sale of securities or, although it would not
normally expect to do so, from the sale of the when-issued securities themselves
(which may have a market value greater or less than the Fund's payment
obligation). The purchase of when-issued securities may affect a Fund's share
price in a manner similar to the use of borrowing.


                                       5

Callable Bonds

         Callable bonds generally have call-protection (that is, a period of
time during which the bonds may not be called) which usually lasts for 7 to 10
years from the date of issue, after which time such bonds may be redeemed by the
issuer. An issuer may generally be expected to call its bonds, or a portion of
them, during periods of declining interest rates, when borrowings may be
replaced at lower rates than those obtained in prior years. If interest rates
decline as the call-protection on callable bonds expires, there is an increased
likelihood that a number of such bonds may in fact be redeemed by the issuers.

Stand-By Commitments

         When a Fund exercises a stand-by commitment that it has acquired from a
dealer with respect to municipal obligations held by it, the dealer normally
pays the Fund an amount equal to (1) the Fund's acquisition cost of the
municipal obligations (excluding any accrued interest which the Fund paid on its
acquisition) less any amortized market premium or plus any amortized market or
original issue discount during the period the Fund owned the securities, plus
(2) all interest accrued on the securities since the last interest payment date
or the date the securities were purchased by the Fund, whichever is later. The
Fund's right to exercise stand-by commitments is unconditional and unqualified
and exercisable by the Fund at any time prior to the underlying securities'
maturity.

         A stand-by commitment is not transferable by a Fund without the
underlying securities, although the Fund could sell the underlying municipal
obligations to a third party at any time. The Fund may pay for stand-by
commitments either separately in cash or by paying a higher price for portfolio
securities which are acquired subject to such a commitment (thus reducing the
yield to maturity otherwise available for the same securities). Each Fund
intends to enter into stand-by commitments only with those banks, brokers and
dealers that in the Adviser's opinion present minimal credit risks.

         Each Fund intends to acquire stand-by commitments solely to facilitate
liquidity and does not intend to exercise its rights thereunder for trading
purposes. The acquisition of a stand-by commitment would not ordinarily affect
the valuation or assumed maturity of the underlying municipal obligations.
Stand-by commitments would not affect the average weighted maturity of the
assets of a Fund.

Fixed, Variable and Floating Rate Obligations

         A variable rate obligation differs from an obligation with a fixed rate
coupon, the value of which fluctuates in inverse relation to interest rate
changes. If interest rates decline below the coupon rate, generally the value of
a fixed rate obligation increases and the obligation sells at a premium. Should
interest rates increase above the coupon rate, generally the value of a fixed
rate obligation decreases and the obligation sells at a discount. The magnitude
of such capital fluctuations is also a function of the period of time remaining
until the obligation matures. Short-term fixed rate obligations are minimally
affected by interest rate changes; the greater the remaining period until
maturity, the greater the fluctuation in value of a fixed rate obligation is
likely to be.

         Variable rate obligation coupons are not fixed for the full term of the
obligation, but are adjusted periodically based upon changes in prevailing
interest rates. As a result, the value of variable rate obligations is less
affected by changes in interest rates. The more frequently such obligations are
adjusted, the less such obligations are affected by interest rate changes during
the period between adjustments. The value of a variable rate obligation,
however, may fluctuate in response to market factors and changes in the
creditworthiness of the issuer.

         By investing in variable rate obligations, a Fund hopes to take
advantage of the normal yield curve function that usually results in higher
yields on longer-term investments. This policy also means that should interest
rates decline, the yield of the Fund will decline, and the Fund and its
shareholders will forego the opportunity for, respectively, capital appreciation
of its portfolio investments and of their shares.



                                       6

<PAGE>

         Should interest rates increase, the yield of the Fund will increase,
and the Fund and its shareholders will forego the opportunity for, respectively,
capital depreciation of its portfolio investments and of their shares. There is
no limitation on the percentage of a Fund's assets that may be invested in
variable rate obligations. However, each Fund will limit the value of its
investments in any variable rate securities that are illiquid and in all other
illiquid securities to 10% or less of its net assets.

         Floating rate obligations also are not fixed, but are adjusted as
specified benchmark interest rates change. In other respects, their
characteristics are similar to variable rate notes, as discussed above.

Yield Factors and Ratings

         Standard & Poor's ("S&P"), Moody's Investors Service, Inc. ("Moody's")
and Fitch Investors Service, Inc. ("Fitch") are private services that provide
ratings of the credit quality of obligations. A description of the ratings
assigned to obligations by Moody's, S&P and Fitch is included in Appendix A. A
Fund may consider these ratings in determining whether to purchase, sell or hold
a security. The ratings represent Moody's, S&P's and Fitch's opinions as to the
quality of the obligations which they undertake to rate. 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. 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. 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 that an issuer's current financial condition may be better or worse
than the rating indicates.

Securities Lending

         A Fund may lend portfolio securities to dealers in municipal
securities, brokers or dealers in corporate or government securities, banks or
other recognized institutional borrowers of securities, provided that cash or
equivalent collateral, equal to at least 100% of the market value of the
securities loaned, is continuously maintained by the borrower with the Fund.
During the time portfolio securities are on loan, the borrower will pay the Fund
an amount equivalent to any dividends or 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 taxable 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. The 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. The Funds do not have the right to vote securities on loan, but
each Fund would terminate the loan and regain the right to vote if that were
considered important with respect to the investment. Because interest from
securities lending is taxable, each Fund presently does not intend to loan more
than 5% of its portfolio securities at any given time.

Reverse Repurchase Agreements

         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. A Fund may engage in reverse repurchase agreements as a means of
raising cash to satisfy redemption requests or for other temporary or emergency
purposes without the necessity of selling portfolio instruments. A Fund may also
engage in reverse repurchase agreements in order to reinvest the proceeds in
other securities or repurchase agreements. Such a use of reverse repurchase
agreements would constitute a form of leverage.

         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

                                       7

<PAGE>

which the proceeds are invested would affect the market value of the Fund's
assets. As a result, such transactions could increase fluctuation in the Fund's
net asset value. 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 the
Fund's yield. While engaging in reverse repurchase agreements, each Fund will
maintain cash or other appropriate liquid securities in a segregated account at
its custodian bank with a value at least equal to the Fund's obligation under
the agreements.

         The ability of a Fund to engage in reverse repurchase agreements is
subject to the Fund's fundamental investment limitation concerning borrowing
described above.

Repurchase Agreements

         A repurchase agreement is an agreement under which U.S. government
obligations or other high-quality debt securities are acquired by a Fund from a
securities dealer or bank subject to resale at a previously agreed-upon price
and date. The resale price reflects an agreed interest rate effective for the
period the securities are held and is unrelated to the interest rate provided by
the securities. In these transactions, the securities acquired by the Fund are
held by a custodian bank 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 agreements. Repurchase agreements are usually for
periods of one week or less, but may be for longer periods. Each Fund will not
enter into repurchase agreements of more than seven days duration if more than
10% of its net assets would be invested in such agreements and other illiquid
investments. A Fund's income from repurchase agreements is taxable income.

         To the extent that proceeds from the sale upon a default of the
obligation to repurchase were less than the repurchase price, a Fund might
suffer a loss. In addition, if bankruptcy proceedings are commenced with respect
to the seller of the securities, realization upon the collateral by the Fund
could be delayed or limited, during which time the value of the Fund's
collateral might decline. However, each Fund has adopted standards for the
parties with whom it will enter into repurchase agreements that the Trust's
Board of Trustees believes are reasonably designed to assure that each party
presents no serious risk of becoming involved in bankruptcy proceedings within
the time frame contemplated by the repurchase agreement.

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 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 wished to purchase the securities, it
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

                                       8

<PAGE>

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. The Funds do not expect ordinarily to hold
futures contracts they have sold until delivery or to use securities they own 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 a Fund will not exactly match
the securities the 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 the 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, the Fund may purchase or
sell futures contracts with a greater or lesser value than the securities it
wishes to hedge or intends to purchase.

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 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 a Fund's investment limitations. Initial margin may
be maintained either in cash or in appropriate liquid 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 the 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. 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. When the Fund has sold futures contracts to hedge
securities it owns, it will not sell those securities (or lend to


                                       9

<PAGE>

another party) while the contracts are outstanding, unless it substitutes other
similar securities for the securities sold or lent. The Fund will not sell
futures contracts with a value exceeding the value of securities it owns, except
that the 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 Future Contracts

         By purchasing an interest rate futures contract, the Fund in effect
becomes exposed to price fluctuations resulting from changes in interest rates,
and by selling a futures contract the Fund neutralizes those fluctuations. If
interest rates fall, the Fund would expect to profit from an increase in the
value of the instrument underlying a futures contract it had purchased, and if
interest rates rise, the 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, the Fund's positions in futures
contracts could have a negative effect on the Fund's net asset value. If
interest rates rise when the Fund has purchased futures contracts, the Fund
could suffer a loss in its futures positions. Similarly, if interest rates fall,
losses in a futures contract a 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 the correct 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 the Fund wishes to hedge or intends to purchase. This may result from
differences between the instrument underlying the futures contracts and the
securities the Fund wishes to hedge or intends to purchase, as would be the
case, for example, if the Fund hedged U.S. Treasury bonds by selling futures
contracts on U.S. Treasury notes.

         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 upward and downward 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.

         A Fund may purchase put options on interest rate futures contracts to
hedge against a decline in the market value of securities the Fund owns. 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, the Fund would
attempt to offset potential depreciation of securities it owns by appreciation
of the put option.

                                       10

<PAGE>

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 would be lost by the Fund. A 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. A
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. A Fund
may close out an option it had 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 purchase or 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 the 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 the correct 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. There is also a risk of imperfect price
correlation between the option and the underlying futures contract.

         Although the Adviser will purchase and write 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, and
might continue to be obligated under an option it had written until the option
expired or was exercised.

Regulatory Notification of Futures and Options Strategies

         The Trust has filed on behalf of the Funds 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 regulations
adopted by the CFTC, futures contracts and related options may be used by a Fund
(a) for hedging purposes, without quantitative limits, and (b) for other
purposes to the extent that the amount of margin deposit on all such non-hedging
futures contracts owned by the Fund, together with the amount of premiums paid
by the Fund on all such non-hedging options held on futures contracts, does not
exceed 5% of the market value of the Fund's net assets. Each Fund will not
purchase futures contracts or related options if as a result more than 25% of
the Fund's total assets would be so invested. These limits on the Fund's
investments in futures contracts are not fundamental and may be changed by the
Board of Trustees 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 the Fund's shareholders.

                 ADDITIONAL PURCHASE AND REDEMPTION INFORMATION

         Each Fund offers two classes of shares, known as Primary Shares and
Navigator Shares. Primary Shares are available from Legg Mason, certain of its
affiliates and unaffiliated entities having an agreement with Legg Mason.
Navigator Shares are currently offered for sale only to Institutional Clients,
to clients of Trust Company, for which Trust Company exercises discretionary
investment management responsibility, to qualified retirement plans managed on a
discretionary basis and having net assets of at least $200 million, 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.
Primary Shares are available to all other investors.

Future First Systematic Investment Plan

         If you invest in Primary Shares, the Prospectus for those shares
explains that you may buy 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 each month
from your Legg Mason account or from your checking account to be used to buy
Primary Shares of the Fund you selected at the per share net asset value
determined on the day the funds are sent from your bank. An account statement
will be sent to you quarterly. 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.

Purchases by Check

         In making purchases of shares by check, you should be aware that checks
drawn on a member bank of the Federal Reserve System will normally be converted
to federal funds and used to purchase shares within two business days of receipt
by Legg Mason or its affiliate. Legg Mason is closed on the days that the New
York Stock Exchange ("Exchange") is closed, which are listed under "Valuation of
Fund Shares". Checks drawn on banks that are not members of the Federal Reserve
System may take up to nine business days to be converted.

Letter of Intention -- (Primary Shares)

         Through a Letter of Intention ("LOI") you may pay the lower sales
charge on the dollar amount of Primary Shares currently being purchased plus the
dollar amount of any purchases you intend to make during the next thirteen
months of shares of this and other Legg Mason funds sold with an initial sales
charge. To take advantage of an LOI you should indicate the total amount you
intend to purchase over the thirteen-month period on the form available from
your Legg Mason or affiliated financial advisor. Holdings acquired up to 90 days
before the LOI is filed will be counted toward completion of the LOI and will be
entitled to a retroactive downward adjustment of the initial sales charge
providing that you bring the prior purchase(s) to the attention of your Legg
Mason or affiliated financial advisor at the time the LOI is filed. The minimum
investment under an LOI is $50,000. Signing an LOI does not obligate you to
purchase the full amount indicated, but you must complete the intended purchase
to obtain the reduced sales charge. The front-end sales charge is waived for all
purchases of Primary Shares of each Fund made through July 31, 1999.

         If the total amount of shares purchased at the end of the eleventh
month does not equal the amount stated in the LOI, you will be notified in
writing by Legg Mason of the amount purchased to date, the amount required to
complete the LOI and the expiration date. If the total purchases indicated on
the LOI are not made within the thirteen-month period, your account will be
charged with the difference between the reduced LOI sales charge and the sales
charge applicable to the purchases actually made. The first purchase under an
LOI must be at least 2.5% of the intended LOI purchases for the Maryland and
Pennsylvania Tax-Free Funds and 1% for the Tax-Free Intermediate Fund. Shares
with a value of up


                                       12

<PAGE>

to 2.5% for the Maryland and Pennsylvania Tax-Free Funds and 1.25% for the
Tax-Free Intermediate Fund, of the intended LOI purchases will be held in escrow
during the thirteen-month period (registered in your name) to assure such
necessary payment. These escrowed shares may not be exchanged for shares of
other Legg Mason funds.

Right of Accumulation -- (Primary Shares)

         Under the Right of Accumulation, the current value of your existing
Primary Shares in Legg Mason funds sold with an initial sales charge may be
combined with the amount of your current purchase in determining the sales
charge for the current purchase. In determining both the current value of
existing shares and the amount of the current purchase, Primary Shares held or
purchased by the investor's spouse, and/or children under the age of 21, may be
included. In order to receive a reduced sales charge for the current purchase,
you must remind your Legg Mason or affiliated financial advisor of your share
balance in Legg Mason funds sold with initial sales charges at the time of the
current purchase.

Reinstatement Privilege --(Primary Shares)

         As described in the Prospectus, shareholders who redeem any of their
Primary Shares may reinstate those shares without a sales charge by notifying
their Legg Mason or affiliated financial advisor of such desire and placing an
order for the amount to be purchased within 90 days after the date of
redemption. The reinstatement will be made at the net asset value per share next
computed after the Notice of Reinstatement and order are received by Legg
Mason's Funds Processing department. The amount of a purchase under this
reinstatement privilege cannot exceed the amount of the redemption proceeds.
Gain on a redemption is taxable regardless of whether the reinstatement
privilege is exercised; however, a loss arising out of a redemption will not be
deductible to the extent the reinstatement privilege is exercised within 30 days
after redemption, and an adjustment will be made to the shareholder's tax basis
for shares acquired pursuant to the reinstatement privilege.

Redemption Services

         Each Fund reserves the right to modify or terminate the wire or
telephone redemption services described in its Prospectus at any time.

         A redemption request received by your Financial Advisor or Service
Provider may be treated as a request for repurchase and, if it is accepted, your
shares will be purchased at the net asset value per share determined as of the
next close of the Exchange. The date of payment for redemption may not be
postponed for more than seven days, and the right of redemption may not be
suspended, except (a) for any periods during which the Exchange is closed (other
than for customary weekend and holiday closings), (b) 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 the Fund's investments or
determination of its net asset value not reasonably practicable, or (c) for such
other periods as the SEC, by 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 for redemption, or combination of requests 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 each Fund's net
asset value per share. Any such redemption payments shall be made with portfolio
securities that are readily marketable. If payment is made in securities, a
shareholder generally will 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. The Funds do 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. Although each Fund may
elect to redeem any shareholder account with a current value of less than $500,
a Fund will not redeem accounts that fall below $500 solely as a result of a
reduction in net asset value per share.

Overview

         Because the Maryland Tax-Free Fund and the Pennsylvania Tax-Free Fund
each concentrates its investments in a specific state, there are risks
associated with investment in each such Fund which would not exist if those
Funds' investments were more widely diversified. These risks include the
possible enactment of new legislation in the applicable state which could affect
Maryland or Pennsylvania municipal obligations, economic factors which could
affect these obligations and varying levels of supply and demand for Maryland or
Pennsylvania municipal obligations.

         The following only highlights some of the more significant financial
trends and problems and is based on information drawn from official statements
and prospectuses relating to securities offerings of the states of the United
States, the State of Maryland and the Commonwealth of Pennsylvania, their
agencies and instrumentalities, as available on the date of this Statement of
Additional Information. The Funds assume no obligation to update this
information.

Maryland Tax-Free Fund

         State Debt The Maryland Constitution prohibits the contracting of State
general obligation debt unless it is authorized by a law levying an annual tax
or taxes sufficient to pay the debt service within 15 years and prohibiting the
repeal of the tax or taxes or their use for another purpose until the debt is
paid. As a uniform practice, each separate enabling act which authorizes the
issuance of general obligation bonds for a given object or purpose has
specifically levied and directed the collection of an ad valorem property tax on
all taxable property in the State. The Board of Public Works is directed by law
to fix by May 1 of each year the precise rate of such tax necessary to produce
revenue sufficient for debt service requirements of the next fiscal year, which
begins July 1. However, the taxes levied need not be collected if or to the
extent that funds sufficient for debt service requirements in the next fiscal
year have been appropriated in the annual State budget. Accordingly, the Board,
in annually fixing the rate of property tax after the end of the regular
legislative session in April, takes account of appropriations of general funds
for debt service.

         There is no general debt limit imposed by the Maryland Constitution or
public general laws, but a special committee created by statute annually submits
to the Governor an estimate of the maximum amount of new general obligation debt
that prudently may be authorized. Although the committee's responsibilities are
advisory only, the Governor is required to give due consideration to the
committee's findings in preparing a preliminary allocation of new general debt
authorization for the ensuing fiscal year. The continuation of the credit
ratings on State debt is dependent upon several economic and political factors,
including the ability to continue to fund a substantial portion of the debt
service on general obligation debt from general fund revenues in the annual
State budget or to raise the rate of State property tax levies, and the ability
to maintain the amount of authorized debt within the range of affordability.

         Consolidated Transportation Bonds are limited obligations issued by the
Maryland Department of Transportation, the principal of which must be paid
within 15 years from the date of issue, for highway, port, transit, rail or
aviation facilities or any combination of such facilities. Debt service on
Consolidated Transportation Bonds is payable from those portions of the excise
tax on each gallon of motor vehicle fuel and the motor vehicle titling tax, all
mandatory motor vehicle registration fees, motor carrier fees, and the corporate
income tax as are credited to the Maryland Department of Transportation, plus
all departmental operating revenues and receipts. Holders of such bonds are not
entitled to look to other sources for payment.

         The Maryland Transportation Authority operates certain highway, bridge
and tunnel toll facilities in the State. The tolls and other revenues received
from these facilities are pledged as security for revenue bonds of the Authority
issued under, and secured by, a trust agreement between the Authority and a


                                       14

<PAGE>

corporate trustee. On November 9, 1994, the Maryland Transportation Authority
issued $162.6 million of special obligation revenue bonds to fund projects at
the Baltimore/Washington International Airport secured by revenues from the
passenger facility charges received by the Maryland Aviation Administration and
from the general account balance of the Transportation Authority. As of March
31, 1998, $370.3 million of the Transportation's revenue bonds were outstanding.

         Certain other instrumentalities of the State government are authorized
to borrow money under legislation which expressly provides that the loan
obligations shall not be deemed to constitute a debt or a pledge of the faith
and credit of the State. The Community Development Administration of the
Department of Housing and Community Development, higher educational institutions
(including St. Mary's College of Maryland, the University of Maryland System,
and Morgan State University), the Maryland Transportation Authority, the
Maryland Water Quality Financing Administration, and the Maryland Environmental
Service have issued and have outstanding bonds of this type. The principal of
and interest on bonds issued by these bodies are payable solely from various
sources, principally fees generated from use of the facilities or enterprises
financed by the bonds.

         The Port of Baltimore is one of the larger foreign trade ports in the
United States and in the world and a significant factor in Maryland's economy.
The total cargo tonnage at the Port had declined from 30,682,730 in 1982 to
25,147,533 in 1997. The Port handles both high value general cargo, including
containers and automobiles, as well as bulk cargo such as coal and grain. The
value of the tonnage handled increased from $14.2 billion in 1982 to $18.8
billion in 1997. The ability of the Port to sustain and improve its volume and
value of cargoes is dependent, in part, upon national and worldwide economic
conditions.

         The Maryland Stadium Authority is responsible for financing and
directing the acquisition and construction of one or more new professional
sports facilities in Maryland. Currently, the Authority operates Oriole Park at
Camden Yards, which opened in 1992. In connection with the construction of that
facility, the Authority issued $155 million in notes and bonds. Those notes and
bonds are lease-backed revenue obligations, the payment of which is secured by,
among other things, an assignment of revenues received under a lease of Oriole
Park at Camden Yards from the Stadium Authority to the State. Annual net debt
service on the Authority's obligations is $14 million.

         The Stadium Authority also has been assigned responsibility for
constructing expansions of the Convention Centers in Baltimore and Ocean City.
The Baltimore Convention Center expansion cost $167 million and is being
financed through a combination of funding from Baltimore City bonds ($50
million), Stadium Authority revenue bonds ($55 million), and State general
obligation bonds ($58 million). The Ocean City Convention Center expansion cost
$33.1 million and is being financed through a combination of funding from Ocean
City and the Stadium Authority. Annual debt service on the obligations
attributable to the Baltimore and Ocean City expansion projects is projected to
be $9,800,000 and $1,490,000, respectively.

         In October 1995, the Stadium Authority and the Baltimore Ravens
(formerly known as the Cleveland Browns) executed a Memorandum of Agreement
which commits the Ravens to occupy a to be constructed football stadium in
Baltimore City. The Agreement was approved by the Board of Public Works and
constitutes a "long-term lease with a National Football League team" as required
by statute for the issuance of Stadium Authority bonds. The Stadium Authority
sold $87.565 million in lease-backed revenue bonds on May 1, 1996. The proceeds
from the bonds, along with cash available from State lottery proceeds,
investment earnings, and other sources will be used to pay project design and
construction expenses of approximately $200 million. The bonds are solely
secured by an assignment of revenues received under a lease of the project from
the Stadium Authority to the State. Authority debt service on the bonds will be
$7.0 million annually.

         The Authority has also been assigned responsibility for construction of
a conference center in Montgomery County. The center is expected to cost
$27,500,000 and is being financed through a combination of funding from
Montgomery County and the Authority. The Authority is authorized to issue up to
$17,600,000 in revenue bonds which it expects to sell during the fiscal year
1999.


                                       15

<PAGE>

         The State has financed and expects to continue to finance the
construction and acquisition of various facilities through conditional purchase,
sale-leaseback, and similar transactions. All of the lease payments under these
arrangements are subject to annual appropriation by the Maryland General
Assembly. In the event that appropriations are not made, the State may not be
held contractually liable for the payments.

         Local Subdivision Debt The counties and incorporated municipalities in
Maryland issue general obligation debt for general governmental purposes. The
general obligation debt of the counties and incorporated municipalities is
generally supported by ad valorem taxes on real estate, tangible personal
property and intangible personal property subject to taxation. The issuer
typically pledges its full faith and credit and unlimited taxing power to the
prompt payment of the maturing principal and interest on the general obligation
debt and to the levy and collection of the ad valorem taxes as and when such
taxes become necessary in order to provide sufficient funds to meet the debt
service requirements. The amount of debt which may be authorized may in some
cases be limited by the requirement that it not exceed a stated percentage of
the assessable base upon which such taxes are levied.

         Other Risk Factors The manufacturing sector of Maryland's economy,
which historically has been a significant element of the State's economic
health, has experienced severe financial pressures and an overall contraction in
recent years. This is due in part to the reduction in defense-related contracts
and grants, which has had an adverse impact that is substantial and is believed
to be disproportionately large compared with the impact on most other states.
The State has endeavored to promote economic growth in other areas, such as
financial services, health care and high technology. Whether the State can
successfully make the transition from an economy reliant on heavy industries to
one based on service and science-oriented businesses is uncertain. Moreover,
future economic difficulties in the service sector and high technology
industries being promoted by Maryland could have an adverse impact on the
finances of the State and its subdivisions, and could adversely affect the
market value of the Bonds in the Maryland Trust or the ability of the respective
obligors to make payments of interest and principal due on such Bonds.

         The State and its subdivisions, and their respective officers and
employees, are defendants in numerous legal proceedings, including alleged tort
and breaches of contract and other alleged violations of laws. Although adverse
decisions in these matters could require extraordinary appropriations not
budgeted for, in the opinion of the Attorney General of Maryland, the legal
proceedings are not likely to have a material adverse effect on the State's
financial position.

Pennsylvania Tax-Free Fund

         State Debt Pennsylvania may incur debt to rehabilitate areas affected
by disaster, debt approved by the electorate, debt for certain capital projects
(such as highways, public improvements, transportation assistance, flood
control, redevelopment assistance, site development and industrial development)
and tax anticipation debt payable in the fiscal year of issuance. Pennsylvania
had outstanding general obligation debt of $4,795 million at June 30, 1997.
Pennsylvania is not permitted to fund deficits between fiscal years with any
form of debt. All year-end deficit balances must be funded within the succeeding
fiscal year's budget. At March 1, 1998, all outstanding general obligation bonds
of Pennsylvania were rated AA- by S&P and Aa3 by Moody's (see Appendix A). There
can be no assurance that the current ratings will remain in effect in the
future. The Pennsylvania Tax-Free Fund assumes no obligation to update this
rating information. Over the five-year period ending June 30, 2003, Pennsylvania
has projected that it will issue bonds totaling $2,984.5 million and retire
bonded debt in the principal amount of $2,350.9 million.

         Certain agencies created by Pennsylvania have statutory authorization
to incur debt for which Pennsylvania appropriations to pay debt service thereon
is not required. As of June 30, 1997, one of these agencies, the Pennsylvania
Turnpike Commission, had total outstanding indebtedness of $1,177.6 million. The
combined total debt outstanding for all other above-mentioned agencies as of
December 31, 1997, was $7,047.4 million. The debt of these agencies is supported
by assets of, or revenues derived


                                       16

<PAGE>

from, the various projects financed and is not an obligation of Pennsylvania.
Some of these agencies, however, are indirectly dependent on Pennsylvania
appropriations. The only obligations of agencies in Pennsylvania that bear a
moral obligation of Pennsylvania are those issued by the Pennsylvania Housing
Finance Agency ("PHFA"), a state-created agency which provides housing for lower
and moderate income families, and The Hospitals and Higher Education Facilities
Authority of Philadelphia ("Hospital Authority"), an agency created by the City
of Philadelphia to acquire and prepare various sites for use as intermediate
care facilities for the mentally retarded.

         Local Government Debt Numerous local government units in Pennsylvania
issue general obligations (i.e., backed by taxing power) debt, including
counties, cities, boroughs, townships and school districts. School district
obligations are supported indirectly by Pennsylvania. The issuance of
non-electoral general obligation debt is limited by constitutional and statutory
provisions. Electoral debt, i.e., that approved by the voters, is unlimited. In
addition, local government units and municipal and other authorities may issue
revenue obligations that are supported by the revenues generated from particular
projects or enterprises. Examples include municipal authorities (frequently
operating water and sewer systems), municipal authorities formed to issue
obligations benefiting hospitals and educational institutions, and industrial
development authorities, whose obligations benefit industrial or commercial
occupants. In some cases, sewer or water revenue obligations are guaranteed by
taxing bodies and have the credit characteristics of general obligation debt.

         Litigation Pennsylvania is currently involved in certain litigation
where adverse decisions could have an adverse impact on its ability to pay debt
service. For instance, in Baby Neal v. Commonwealth of Pennsylvania, the
American Civil Liberties Union filed a lawsuit against the Commonwealth seeking
an order that would require the Commonwealth to provide additional funding for
child welfare services. County of Allegheny v. Commonwealth of Pennsylvania
involves litigation regarding the state constitutionality of the statutory
scheme for county funding of the judicial system. In Pennsylvania Association of
Rural and Small Schools v. Casey, the constitutionality of Pennsylvania's system
for funding local school districts has been challenged. No estimates for the
amount of these claims are available.

         Other Factors Pennsylvania historically has been identified as a heavy
industry state, although that reputation has changed with the decline of the
coal, steel and railroad industries and the resulting diversification of
Pennsylvania's industrial composition. The major new sources of growth are in
the service sector, including trade, medical and health services, educational
and financial institutions. Manufacturing has fallen behind both the services
sector and the trade sector as the largest single source of employment in
Pennsylvania. Between 1987 and 1997, employment in Pennsylvania has grown each
year at a rate slightly in excess of the growth in employment in the
mid-Atlantic region, but less than that of the U.S. as a whole, during the same
period. Pennsylvania's average unemployment rate for the years 1991 through 1995
and 1997 remained slightly above the nation's annual average unemployment rate,
while it was slightly below the national average in 1996. The unadjusted
unemployment rate for Pennsylvania for May, 1998 was 4.5% and for the United
States for May, 1998 was 4.2%. The population of Pennsylvania, 12.02 million
people in 1997, according to the U.S. Bureau of the Census, represents a slight
increase from the 1988 estimate of 11.846 million. Per capita income in
Pennsylvania was $24,803 for calendar year 1996, slightly above the per capita
income of the United States of $24,426. Pennsylvania's General Fund, which
receives all tax receipts and most other revenues and through which debt service
on all general obligations of Pennsylvania are made, closed fiscal years ended
June 30, 1995, June 30, 1996 and June 30, 1997 with fund balances of $688.304
million, $635.182 million, and $1,364.9 million respectively.

                           ADDITIONAL TAX INFORMATION

         The following is a general summary of certain 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.


                                       17

<PAGE>

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
the sum of its net interest income excludable from gross income under section
103(a) of the Code plus its investment company taxable income (generally,
taxable net investment income plus net short-term capital gain, if any)
("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 other income (including gains from options and
futures contracts) derived with respect to its business of investing in
securities ("Income Requirement"); (2) at the close of each quarter of the
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 the Fund's taxable
year, not more than 25% of the value of its total assets may be invested in the
securities (other than U.S. government securities or the securities of other
RICs) of any one issuer.

         Dividends paid by a Fund will qualify as "exempt-interest dividends"
(as defined in each Prospectus), and thus will be excludable from gross income
by its shareholders, if the Fund satisfies the additional requirement that, at
the close of each quarter of the Fund's taxable year, at least 50% of the value
of its total assets consists of securities the interest on which is excludable
from gross income under section 103(a) of the Code; each Fund intends to
continue to satisfy this requirement. The portion of each dividend excludable
from a Fund's shareholder's gross income may not exceed the Fund's net
tax-exempt income.

         To the extent a Fund invests in instruments that generate taxable
income, distributions of the interest earned thereon will be taxable to the
Fund's shareholders as ordinary income to the extent of its earnings and
profits. Moreover, if a Fund realizes capital gains as a result of market
transactions, any distributions of those gains will be taxable to its
shareholders.

         If Fund shares are sold at a loss after being held for six months or
less, the loss will be disallowed to the extent of any exempt-interest dividends
received with respect to those shares, and any portion of the loss that is not
disallowed will be treated as long-term, instead of short-term, capital loss to
the extent of any capital gain distributions received with respect thereto.

         Up to 85% of social security and railroad settlement benefits may be
included in taxable income for recipients whose adjusted gross income (including
income from tax-exempt sources such as a Fund) plus 50% of their benefits
exceeds certain base amounts. Exempt-interest dividends from a Fund still are
tax-exempt to the extent described in each Prospectus; they are only included in
the calculation of whether a recipient's income exceeds the established amounts.

         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 (taxable) 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 capital gain
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 the Fund and received by the shareholders on December 31 if the distributions
are paid by the Fund during the following January. Accordingly, those
distributions will be reportable by shareholders for the year in which that
December 31 falls.

         A Fund may purchase zero coupon or other municipal obligations issued
with original issue discount. As a holder of those securities, a Fund must take
into account for purposes of the Income


                                       18

<PAGE>

Requirement the original issue discount that accrues thereon during the taxable
year, even if the Fund receives no corresponding payment on the securities
during the year. Because each Fund annually must distribute substantially all of
its income, including accrued original issue discount (even if that discount is
tax-exempt), to satisfy the Distribution Requirement, 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
the Fund's cash assets or from the proceeds of sales of portfolio securities, if
necessary. The Fund may realize capital gains or losses from those dispositions,
which would increase or decrease its investment company taxable income and/or
net capital gain (the excess of net long-term capital gain over net short-term
capital loss).

Hedging Instruments

         The use of hedging instruments, such as writing (selling) and
purchasing options and futures 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 options and futures contracts derived by a Fund with respect to its
business of investing in securities will be taxable and will qualify as
permissible income under the Income Requirement.

State and Local Income Tax

         The exemption of certain interest income for federal income tax
purposes does not necessarily result in exemption thereof under the income or
other tax laws of any state or local taxing authority. A shareholder may be
exempt from state and local taxes on dividends attributable to interest income
derived from obligations of the state and municipalities or other localities of
the state in which he or she is a resident, but generally will be taxed on
dividends attributable to interest income derived from obligations of other
jurisdictions. Shareholders receive notification annually of the portion of each
Fund's tax-exempt income attributable to each state. Shareholders should consult
their tax advisers about the tax status in their own states and localities of
distributions from each Fund.

                            VALUATION OF FUND SHARES

         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
dividing the value of the total assets attributable to that class, less
liabilities attributable to that class, 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, Presidents' Day, Good Friday, Memorial Day, Independence
Day, Labor Day, Thanksgiving, and Christmas. When market quotations are readily
available, portfolio securities are valued based upon market quotations,
provided such quotations adequately reflect, in the Adviser's judgment, the fair
value of the security. For valuation purposes, the market quotation shall be the
mean of the most recent bid and asked prices quoted by the dealers. Where such
market quotations are not readily available, securities are valued based upon
appraisals received from an independent 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 Trust's Board of Trustees. 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 Trust's Board of Trustees. Premiums received on the
sale of put and call options are included in each Fund's net asset value, and
the current market value of options sold by a Fund will be subtracted from its
net assets.

                             PERFORMANCE INFORMATION

         The following tables show the value, as of the end of each fiscal year,
of a hypothetical investment of $10,000 made in each Fund at that Fund's
respective commencement of operations (Primary Shares). Each table assumes that
all dividends and capital gain distributions are reinvested in


                                       19

<PAGE>

the respective Fund. Each table includes the effect of all charges and fees
applicable to Primary Shares the respective Fund has paid. (There are no
redemption fees.) The tables do not include the effect of any income tax that an
investor would have to pay on distributions. Performance data is only historical
and is not intended to indicate future results.

         If the investor had not reinvested dividends and capital gain
distributions, the total value of the hypothetical investment as of March 31,
1998 would have been $10,840, and the investor would have received a total of
$4,044 in distributions. If the Adviser had not waived certain Fund expenses in
each of the fiscal years, returns would have been lower.

</TABLE>

* November 9, 1992 (commencement of operations) to March 31, 1993.

         If the investor had not reinvested dividends and capital gain
distributions, the total value of the hypothetical investment as of March 31,
1998 would have been $10,407, and the investor would have received a total of
$2,471 in distributions. If the Adviser had not waived certain Fund expenses in
each fiscal year, returns would have been lower.

         Total Return Calculations Average annual total return quotes used in
each Fund's advertising and other promotional materials ("Performance
Advertisements") are calculated 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 the average annual change in the value of an initial $1,000
investment over the period. In calculating the ending redeemable value, the
Maryland Tax-Free and Pennsylvania Tax-Free's maximum 2.75% initial sales charge
or the Tax-Free Intermediate's maximum 2.00% initial sales charge is deducted
from the initial $1,000 payment and all dividends and capital gain distributions
by a Fund are assumed to have been reinvested at net asset value on the
reinvestment dates during the period. Cumulative and average annual returns for
the year ended March 31, 1998 are contained in each Fund's prospectus. The
front-end sales charge is waived for all purchases of Primary Shares of each
Fund made through July 31, 1999.

         Yield Yield figures used in each Fund's Performance Advertisements are
calculated by dividing the Fund's net investment income for a 30-day period
("Period"), by the average number of shares 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
                        ---


                                 21

<PAGE>

                        cd
where:      a   =   dividends and 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 net investment income earned
during the Period (variable "a" in the above formula), each 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 a Fund, interest earned during the
Period is then determined by totaling the interest earned on all debt
obligations. For purposes of these calculations, the maturity of an obligation
with one or more call provisions is assumed to be the next date on which the
obligation reasonably can be expected to be called or, if none, the maturity
date.

         Tax-exempt yield is calculated according to the same formula except
that a = interest exempt from federal income tax earned during the Period. This
tax-exempt yield is then translated into tax equivalent yield according to the
following formula:

TAX EQUIVALENT YIELD = (  E  ) = t
                        -----
                        l - p

         E = tax-exempt yield
         p = stated income tax rate
         t = taxable yield

effect of tax equivalent yields using information such as that set forth below:

^ Based on 1997 tax rates


         For the 30-day period ended March 31, 1998, the Maryland Tax-Free
Fund's yield and tax equivalent yield (assuming a 21.7% blended tax rate) were
4.63% and 5.91%, respectively. The Pennsylvania Tax-Free Fund's yield and tax
equivalent yield (assuming an 17.4% blended tax rate) for the same period were
4.69% and 5.68%, respectively. The Tax-Free Intermediate Fund's yield and tax
equivalent yield (assuming a 15% tax rate) for the same period were 4.01% and
4.72%, respectively.

         Other Information From time to time, in reports and promotional
literature, each class of shares of a Fund's performance may be compared to
indices of broad groups of managed and unmanaged securities considered to be
representative of or similar to Fund portfolio holdings such as the Bond Buyer
20, Lipper General Purpose Municipal Bond Average, Lipper Maryland State
Municipal Bond Fund Average (Maryland Tax-Free Fund only) and Shearson
Lehman/American Express Municipal Bond Index. Securities indices may take no
account of the cost of investing or of any tax consequences of distributions.
The Funds may invest in securities not included in the indices to which they
make such comparisons.

         A Fund may also cite rankings and ratings and compare the return of a
class with data published by Lipper Analytical Services, Inc. ("Lipper"), CDA
Investment Technologies, Inc., Wiesenberger Investment Company Services, Value
Line, Morningstar, and other services or publications that monitor, compare
and/or rank the performance of investment companies. A Fund may also refer in
such materials to mutual fund performance rankings, ratings and comparisons with
funds having similar investment objectives and other mutual funds reported
periodically in national financial publications such as MONEY Magazine, FORBES,
BUSINESS WEEK and BARRON's.

         A Fund may compare the investment return of a class to the return on
certificates of deposit and other forms of bank deposits, and may quote from
organizations that track the rates offered on such deposits. Bank deposits are
insured by an agency of the federal government up to specified limits. In
contrast, Fund shares are not insured, the value of Fund shares may fluctuate,
and an investor's shares, when redeemed, may be worth more or less than the
investor originally paid for them. Unlike the interest paid on a certificate of
deposit, which remains at a specified rate for a specified period of time, the
return of each class of shares will vary.

         In advertising, a 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. A Fund may use other recognized
sources as they become available.

         A 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.


                                       23

<PAGE>

         The 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.

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

         The 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.

         The 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 advisers for private
accounts and mutual funds with assets of more than $74.4 billion as of June 30,
1998.

     **  Represents aggregate compensation paid to each trustee during the
         calendar year ended December 31, 1997. There are nine open-end

         eighteen funds).


                          THE FUNDS' INVESTMENT ADVISER

         The Adviser, a Maryland corporation, is located at 100 Light Street,
Baltimore, Maryland 21202. The Adviser is a wholly owned subsidiary of Legg
Mason, Inc. (a financial services holding company), which also is the parent of
Legg Mason Wood Walker, Incorporated. The Adviser serves as each Fund's
investment adviser and manager under an Investment Advisory and Management
Agreement ("Advisory Agreement") dated March 25, 1991. Continuation of the
Agreement was most recently approved by the Board of Trustees on November 7,
1997. Effective January 1, 1998, the Advisory Agreement was transferred to the
Adviser; prior to that date, LMFA a wholly owned subsidiary of Legg Mason, Inc.,
served as each Fund's investment adviser and manager under the Advisory
Agreement. The Advisory Agreement provides that, subject to overall direction by
the Board of Trustees, the Adviser manages the investment and other affairs of
each Fund. The Adviser is responsible for managing each Fund consistent with the
Funds' investment objectives and policies described in their Prospectuses and
this Statement of Additional Information. The Adviser also is obligated to (a)
furnish each Fund with office space and executive and other personnel necessary
for the operations of the Fund; (b) supervise all aspects of each Fund's
operations; (c) bear the expense of certain informational and purchase and
redemption services to each Fund's shareholders; (d) arrange, but not pay for,
the periodic updating of prospectuses, proxy material, tax returns and reports
to shareholders and state and federal regulatory agencies; and (e) report
regularly to the Trust's officers and trustees. The Adviser and its affiliates
pay all the compensation of trustees and officers of the Trust who are employees
of the Adviser. Each Fund pays all its other expenses which are not expressly
assumed by the Adviser. These expenses include, among others, interest expense,
taxes, auditing and accounting fees, distribution fees, if any, fees and
expenses of the independent trustees of the Trust, brokerage fees and
commissions, expenses of preparing prospectuses and of printing and distributing
prospectuses annually to existing shareholders, custodian charges, transfer
agency fees, legal expenses, insurance expenses, association membership dues,
governmental fees, expenses of registering and qualifying Fund shares for sale
under federal and state law, and the expense of reports to shareholders,
shareholders' meetings and proxy solicitations. Each Fund also pays the expenses
for maintenance of its financial books and records, including computation of the
Fund's daily net asset value per share and dividends. Each Fund is also liable
for such nonrecurring expenses as may arise, including litigation to which the
Fund may be a party. Each Fund also may have an obligation to

                                       26

<PAGE>

indemnify the trustees and officers of the Trust with respect to litigation.

         Under the Advisory Agreement, the Adviser 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 Advisory Agreement, except a loss
resulting from a breach of fiduciary duty with respect to the receipt of
compensation 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.

         With respect to each Fund, the Advisory Agreement terminates
automatically upon assignment. It also is terminable at any time without penalty
by vote of the Trust's Board of Trustees, by vote of a majority of each Fund's
outstanding voting securities, or by the Adviser, on not less than 60 days'
notice to the other party to the Agreement and may be terminated immediately
upon the mutual written consent of both parties to the Agreement.

         As explained in the Prospectuses, the Adviser receives for its services
a fee, calculated daily and payable monthly, at an annual rate of 0.55% of the
average daily net assets of each Fund. The Adviser has agreed to waive its fees
to the extent its expenses (exclusive of taxes, interest, brokerage and
extraordinary expenses) exceed during any month annual rates of each Fund's
average daily net assets for such month in accordance with the following
schedules. The fee waiver for Maryland Tax-Free will expire on July 31, 1999, or
when the Fund's net assets reach $200 million, whichever occurs first. The fee
waiver for Pennsylvania Tax-Free will expire on July 31, 1999, or when the
Fund's net assets reach $125 million, whichever occurs first. The fee waiver for
Tax-Free Intermediate will expire July 31, 1999, or when the Fund's net assets
reach $100 million, whichever occurs first.

           Tax-Free Intermediate Fund          $209,159     $252,670    $287,375

         Under the Advisory 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 Adviser.

         Pursuant to an agreement with the Adviser ("Administration Agreement")
dated January 1, 1998, LMFA serves as the Fund's administrator whereby it is
obligated to (a) furnish each Fund with office space and executive and other
personnel necessary for the operations of the funds; (b) supervise all aspects
of each Fund's operations; (c) bear the expense of certain informational and
purchase and redemption services to fund shareholders; (d) arrange, but not pay
for, the periodic updating of prospectuses, proxy material, tax returns and
reports to shareholders and state and federal regulatory agencies; and (e)
report regularly to the Trust's officers and directors. The Adviser pays LMFA,
pursuant to the Administration Agreement, a fee equal to an annual rate of 0.05%
of each Fund's average daily net assets. For the period January 1, 1998 to March
31, 1998, the Adviser paid LMFA $18,069 for its services as administrator.

         Under the Administration Agreement, LMFA will not be liable for an
error of judgment or mistake of law or for any loss suffered by the Adviser or
the Funds in connection with the performance of the Administration Agreement,
except that LMFA may be liable for a loss resulting from a breach of fiduciary
duty with respect to the receipt of compensation 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 obligation
or duties thereunder.

         To mitigate the possibility that a Fund will be affected by personal
trading of employees, the Trust 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


                                       28

<PAGE>

transactions. These policies comply, in all material respects, with the
recommendations of the Investment Company Institute.

                             THE FUNDS' DISTRIBUTOR

         Legg Mason acts as distributor of each Fund's shares pursuant to an
Underwriting Agreement with the Trust. The Underwriting Agreement obligates Legg
Mason to promote the sale of Fund shares and to pay certain expenses in
connection with its distribution efforts, including expenses 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 existing shareholders at the Fund's
expense) and for supplementary sales literature and advertising costs.

         Fairfield Group, Inc., a wholly owned subsidiary of Legg Mason, Inc.,
with principal offices at 200 Gibraltar Road, Horsham, Pennsylvania, may act as
a dealer for Navigator Shares pursuant to a Dealer Agreement with Legg Mason.
Legg Mason and LMFA may make payments out of their own assets to Fairfield or
others to support the distribution of Navigator Shares and Shareholder
servicing.

         Each Fund has adopted a Distribution and Shareholder Services Plan
("Plan") which, among other things, permits each Fund to pay Legg Mason fees for
its services related to sales and distribution of Primary Shares and the
provision of ongoing services to Primary Class shareholders. Payments are made
only from assets attributable to Primary Shares. Under the Plan, the aggregate
fees may not exceed an annual rate of 0.25% of the Fund's average daily net
assets attributable to Primary Shares. Distribution activities for which such
payments may be made include, but are not limited to, compensation to persons
who engage in or support distribution and redemption of shares, printing of
prospectuses and reports for persons other than existing shareholders,
advertising, preparation and distribution of sales literature, overhead, travel
and telephone expenses, all with respect to Primary Shares only. Legg Mason may
pay all or a portion of the fees to its financial advisors. The Plan has been
amended, effective July 1, 1993, to make clear that, of the aggregate 0.25%
fees, 0.125% is paid for distribution services and 0.125% is paid for ongoing
services to shareholders. The amendments also specify that the Fund may not pay
more in distribution fees than 6.25% of total new gross assets, plus interest,
as specified in the Rules of Fair Practice of the National Association of
Securities Dealers, Inc. ("NASD").

         Continuation of the Plan was most recently approved on November 7, 1997
by the Board of Trustees of the Trust, including a majority of the trustees who
are not "interested persons" of the Trust 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 Trustees"). In approving the
continuance of the Plan, in accordance with the requirements of Rule 12b-1, the
trustees determined that there was a reasonable likelihood that the Plan would
benefit each Fund and its Primary Class shareholders. The trustees considered,
among other things, the extent to which the potential benefits of the Plan to
each Fund's Primary Class shareholders could outweigh the costs of the Plan; the
likelihood that the Plan would succeed in producing such potential benefits; the
merits of certain possible alternatives to the Plan; and the extent to which the
retention of assets and additional sales of each Fund's Primary Shares would be
likely to maintain or increase the amount of compensation paid by a Fund to its
Adviser.

         In considering the costs of the Plan, the trustees gave particular
attention to the fact that any payments made by a Fund to Legg Mason under the
Plan would increase the Fund's level of expenses in the amount of such payments.
Further, the trustees recognized that the Adviser would earn greater management
fees if a Fund's assets were increased, because such fees are calculated as a
percentage of the Fund's assets and thus would increase if net assets increase.
The trustees further recognized that there can be no assurance that any of the
potential benefits described below would be achieved if the Plan were
implemented.

         Among the potential benefits of the Plan, the trustees noted that the
payment of commissions and service fees to Legg Mason and its financial advisors
could motivate them to improve their sales efforts with respect to each Fund's
Primary Shares and to maintain and enhance the level of services they provide to
the Funds' Primary Class shareholders. These efforts, in turn, could lead to
increased sales


                                       29

<PAGE>

and reduced redemptions, eventually enabling a Fund to achieve economies of
scale and lower per share operating expenses. Any reduction in such expenses
would serve to offset, in whole or in part, the additional expenses incurred by
a Fund in connection with the Plan. Furthermore, the investment management of a
Fund could be enhanced, as net inflows of cash from new sales might enable its
portfolio manager to take advantage of attractive investment opportunities, and
reduced redemptions could eliminate the potential need to liquidate attractive
securities positions in order to raise the funds necessary to meet the
redemption requests.

         As compensation for its services and expenses, Legg Mason receives from
each Fund an annual distribution fee equivalent to 0.125% of its average daily
net assets attributable to Primary Shares and a service fee equivalent to 0.125%
of its average daily net assets attributable to Primary Shares in accordance
with the Plan. The distribution and service fees are calculated daily and
payable monthly. Legg Mason has voluntarily agreed to waive its fees and
reimburse each Fund if and to the extent its expenses (exclusive of taxes,
interest, brokerage and extraordinary expenses) exceed during any month annual
rates of each Fund's average daily net assets attributable to Primary Shares for
such month, or certain asset levels, whichever occurs first, in accordance with
the schedules described previously.


         For the years ended March 31, the Funds paid Legg Mason distribution
and service fees of:

                                              1998         1997         1996
                                              ----         ----         ----
           Maryland Tax-Free Fund           $375,710      $371,914     $368,033
           Pennsylvania Tax-Free Fund       $165,830      $166,129     $165,248
           Tax-Free Intermediate Fund       $145,605      $142,613     $136,619

         The Plan will continue in effect only so long as it is approved at
least annually by the vote of a majority of the Board of Trustees, including a
majority of the 12b-1 Trustees, cast in person at a meeting called for the
purpose of voting on the Plan. The Plan may be terminated with respect to a Fund
by a vote of a majority of 12b-1 Trustees or by vote of a majority of the
outstanding Primary Shares of that Fund. Any change in the Plan that would
materially increase the distribution costs to a Fund requires shareholder
approval; otherwise, the Plan may be amended by the trustees, including a
majority of the 12b-1 Trustees.

         In accordance with Rule 12b-1, the Plan provides that Legg Mason will
submit to the Trust's Board of Trustees, and the trustees will review at least
quarterly, a written report of any amounts expended pursuant to the Plan and the
purposes for which expenditures were made. In addition, as long as the Plan is
in effect, the selection and nomination of the Independent Trustees will be
committed to the discretion of such Independent Trustees.

         For the fiscal year ended March 31, 1998, Legg Mason incurred the
following expenses:

         The foregoing are estimated and do not include all expenses fairly
allocable to Legg Mason's or its affiliates' efforts to distribute each Fund's
Primary Shares.

         Initial sales charges on purchases of shares of the Funds are paid to
Legg Mason. Initial sales charges are waived on purchases of Primary Shares of
each Fund made through July 31, 1999. Sales charges received by Legg Mason from
sales of each Fund are as follows:

                                          1998           1997          1996

           Maryland Tax-Free            $191,000        $315,000     $347,000
           Pennsylvania Tax-Free        $84,000         $152,000     $174,000
           Tax-Free Intermediate        $0              $0           $100,000


                      PORTFOLIO TRANSACTIONS AND BROKERAGE

         Under each Advisory Agreement, the Adviser is responsible for the
execution of portfolio transactions. Corporate, municipal and government debt
securities are generally traded on the over-the-counter ("OTC") 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 will
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 to brokers who provide research
and analysis. The Funds 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 brokers who provide supplemental investment and market research and
securities and economic analysis, and may pay to these brokers a higher
brokerage commission than may be charged by other brokers. Such research and
analysis may be useful to the Adviser in connection with services to clients
other than the Funds. The Adviser's fee is not reduced by reason of its
receiving such brokerage and research services.

         Although the Funds do not expect to purchase securities on a commission
basis, the Funds may use Legg Mason to effect agency transactions in listed
securities at commission rates and under circumstances consistent with the
policy of best execution. Commissions paid to Legg Mason will not exceed "usual
and customary brokerage commissions." Rule 17e-1 under the 1940 Act defines
"usual and customary" commissions to include amounts which are "reasonable and
fair compared to the commission, fee or other remuneration received by other
brokers in connection with comparable transactions involving similar securities
being purchased or sold on a securities exchange during a comparable period of
time." In the OTC market, the Funds generally will deal with responsible primary
market makers unless a more favorable execution can otherwise be obtained.

         Except as permitted by SEC rules or orders, the Funds may not buy
securities from, or sell securities to, Legg Mason or its affiliated persons as
principal. The Trust's Board of Trustees has adopted procedures in conformity
with Rule 10f-3 under the 1940 Act whereby each Fund may purchase securities
that are offered in certain underwritings in which Legg Mason or any of its
affiliated persons is a participant. These procedures, among other things, limit
a Fund's investment in the amount of securities of any class of securities
offered in an underwriting in which Legg Mason or any of its affiliated persons
is a participant so that the Fund together with all other registered investment
companies having the same


                                       31

<PAGE>

adviser, may not purchase more than 25% of the principal amount of the offering
of such class. In addition, a Fund may not purchase securities during the
existence of an underwriting if Legg Mason is the sole underwriter of those
securities or if such purchase is designated as a "group sale" in an
underwriting in which Legg Mason participates. Because Legg Mason is a principal
underwriter of municipal obligations and because new issues of municipal
securities often are sold pursuant to group sales, the Funds may be precluded
from purchasing certain new issues of municipal securities or may be permitted
to make only limited investments therein.

         Section 11(a) of the Securities Exchange Act of 1934 prohibits Legg
Mason from executing transactions on an exchange for its affiliates, such as the
Funds, unless the affiliate expressly consents by written contract.
The Advisory Agreements expressly provide such consent.

         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 Fund. In other cases, however, a Fund's ability to
participate in large-volume transactions may produce better executions and
prices.

Portfolio Turnover

         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. Each Fund's portfolio turnover rate may vary from year to year,
depending on market conditions. A high turnover rate (100% or more) will involve
correspondingly greater transaction costs, which will be borne directly by a
Fund. It may also change the character of capital gains, if any, realized by a
Fund and would affect dividends paid to shareholders because short-term capital
gains are taxable as ordinary income. For the years ended March 31, 1998 and
1997, the Maryland Tax-Free Fund's portfolio turnover rates were 18.9% and 6.0%,
respectively; the Pennsylvania Tax-Free Fund's portfolio turnover rates were
14.1% and 13.6%, respectively; and the Tax-Free Intermediate Fund's portfolio
turnover rates were 9.0% and 8.9%, respectively.


                            THE TRUST'S CUSTODIAN AND
                     TRANSFER AND DIVIDEND-DISBURSING AGENT

         State Street Bank and Trust Company, P.O. Box 1713, Boston
Massachusetts, serves as custodian of the Funds' assets. BFDS, P.O. Box 953,
Boston, Massachusetts 02103 serves as transfer and dividend-disbursing agent and
administrator of various shareholder services. Legg Mason also assists BFDS with
certain of its duties as transfer agent, for which BFDS pays Legg Mason a fee.
Each Fund reserves the right, upon 60 days' written notice, to make other
charges to investors to cover administrative costs.

                                OTHER INFORMATION

         The Trust is an entity of the type commonly known as a "Massachusetts
business trust." Under Massachusetts law, shareholders of each Fund could, under
certain circumstances, be held personally liable for the obligations of that
Fund and of the other Funds. However, the Trust's Declaration of Trust disclaims
shareholder liability for acts or obligations of the Trust or the Funds and
requires that notice of such disclaimer be given in each note, bond, contract,
instrument, certificate or undertaking made or issued by the trustees or by any
officers or officer by or on behalf of the Trust, a Fund, the trustees or any of
them in connection with the Trust. The Declaration of Trust provides for
indemnification from each Fund's property for all losses and expenses of any
Fund shareholder held personally liable for the obligations of that Fund. Thus,
the risk of a shareholder's incurring financial loss on account of shareholder
liability is limited to circumstances in which a Fund itself would be unable to
meet its


                                       32

<PAGE>

obligations, a possibility which the Adviser believes is remote. Upon payment of
any liability incurred by a Fund shareholder solely by reason of being or having
been a shareholder, the shareholder paying such liability will be entitled to
reimbursement from the general assets of that Fund. The trustees intend to
conduct the operations of each Fund in such a way as to avoid, as far as
possible, ultimate liability of the shareholders for liabilities of each Fund.

                              RATINGS OF SECURITIES



1.       Description of Moody's Investors Service, Inc. ("Moody's") Ratings

Municipal Bonds

         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, fluctuation of protective
elements may be of greater amplitude or there may be other elements present
which make long-term risks appear somewhat larger than in 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 sometime 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.

Municipal Notes

         Moody's ratings for state and municipal notes and other short-term
obligations are designated Moody's Investment Grade ("MIG") and for variable
rated demand obligations are designated Variable Moody's Investment Grade
("VMIG"). This distinction is in recognition of the differences between
short-term credit risk and long-term credit risk. Notes bearing the designation
MIG-1 or VMIG-1 are of the best quality, enjoying strong protection by
established cash flows, superior liquidity support or demonstrated broad-based
access to the market for refinancing.

         Moody's applies numerical modifiers 1, 2 and 3 in each generic rating
classification from Aa through B. The modifier 1 indicates that the security
ranks in the higher end of its generic rating, the modifier 2 indicates a
mid-range rating; the modifier 3 indicates that the issue ranks in the lower end
of its generic rating.

Commercial Paper

         The rating Prime-1 is the highest commercial paper rating assigned by
Moody's. Issuers with a Prime-1 ("P-1") rating will normally have the following
characteristics: (1) leading market positions in well-established industries;
(2) high rates of return on funds employed; (3) conservative capitalization
structures with moderate reliance on debt and ample asset protection; (4) broad
margins in earning coverage of fixed financial charges and high internal cash
generation; and (5) well-established access to a range of financial markets and
assured sources of alternate liquidity.


                                      A-1

<PAGE>


2.     Description of Standard & Poor's  ("S&P")

Municipal Bonds

       AAA--This is the highest rating assigned by S&P to an obligation and
indicates an extremely strong capacity to pay principal and interest.

       AA--Bonds rated AA also qualify as high-quality debt obligations.
Capacity to pay principal and interest is very strong, and in the majority of
instances they differ from AAA issues only in small degree.

       A--Bonds rated A have a strong capacity to pay principal and interest,
although they are somewhat more susceptible to the adverse effects of changes in
circumstances and economic conditions.

       BBB--Bonds which are 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 principal and interest for
bonds in this category than for bonds in the A category.

       S & P may assign (+) or (-) modifiers to indicate  relative  strength or
weakness within a particular rating category.

Municipal Notes

       Municipal notes with maturities of three years or less are usually given
note ratings by S&P to distinguish more clearly the credit quality of notes as
compared to bonds. Notes rated SP-1 have a very strong or strong capacity to pay
principal and interest. Those issues determined to possess overwhelming safety
characteristics are given the designation SP-1+.

Commercial Paper

       A-1. This designation indicates that the degree of safety regarding
timely payment is either overwhelming or very strong. Those issues determined to
possess extremely strong safety characteristics are denoted with a plus (+) sign
designation.

       A-2. Capacity for timely payment on issues with this designation is
satisfactory. However, the relative degree of safety is not as high as for
issues designated "A-1".

3.     Description of Fitch Investors Service, Inc. ("Fitch") Ratings

Investment Grade Bonds

       AAA--Bonds considered to be investment grade and of the highest credit
quality. The obligor has an exceptionally strong ability to pay interest and
repay principal, which is unlikely to be affected by reasonable foreseeable
events.

       AA--Bonds considered to be investment grade and of very high credit
quality. The obligor's ability to pay interest and repay principal is very
strong, although not quite as strong as bonds rated "AAA". Because bonds rated
in the "AAA" and "AA" categories are not significantly vulnerable to foreseeable
future developments, short-term debt of these issuers is generally rated "F-1+".

       A--Bonds considered to be investment grade and of high credit quality.
The obligor's ability to pay interest and repay principal is considered to be
strong, but may be more vulnerable to adverse change in economic conditions and
circumstances than bonds with higher ratings.

       BBB--Bonds considered to be investment grade and of satisfactory credit
quality. The obligor's


                                      A-2

<PAGE>


ability to pay interest and repay principal is considered to be adequate.
Adverse changes in economic conditions and circumstances, however, are more
likely to have adverse impact on these bonds, and therefore impair timely
payment. The likelihood that the ratings of these bonds will fall below
investment grade is higher than for bonds with higher ratings.

       Plus (+) Minus (-)--Plus and minus signs are used with a rating symbol to
indicate the relative position of a credit within the rating category. Plus and
minus signs, however, are not used in the "AAA" category.

Short-term Ratings

       F-1+--Exceptionally Strong Credit Quality. Issues assigned this rating
are regarded as having the strongest degree of assurance for timely payment.

       F-1--Very Strong Credit Quality. Issues assigned this rating reflect
assurance of timely payment only slightly less in degree than issues rated
"F-1+".
