                                                         Washington Fund  

                                   The Funds

GOAL / APPROACH

      Each fund seeks the maximum amount of interest income exempt from federal
      income tax as is consistent with reasonable risk. Each fund (except for
      the National fund) also seeks as high a level of interest income exempt
      from its state's personal income tax as is consistent with reasonable
      risk. The New York fund also seeks as high a level of interest income
      exempt from New York City personal income tax as is consistent with
      reasonable risk. At present, neither Texas nor Washington imposes a
      personal income tax.

      To pursue its goal, each fund invests in municipal bonds which are
      investment grade. Under normal market conditions, each fund attempts to be
      80% invested in municipal bonds, the interest on which is exempt from
      federal, its state's and, in the case of New York fund, New York City
      personal income tax. Under normal circumstances, we intend to maintain the
      average weighted stated maturity of each fund at between ten and
      thirty-five years.

      In selecting bonds, we focus on:

      o     Credit Quality - an issuer's ability to pay principal and interest 

      o     Call Protection - assurance by an issuer that it will not redeem a
            bond earlier than anticipated

      o     Income Tax Exemption - the bond issuer's ability to pay interest
            free from federal, state and/or local personal income taxes

      o     Total Return Potential - the return possibilities for an investment
            over a period of time, including appreciation and interest

      While typically fully invested, at times we may take a temporary defensive
      position in: (i) short-term tax-exempt securities, and (ii) cash,
      investment grade commercial paper, and short-term U.S. Government
      Securities (limited to 20% of our assets). This could reduce tax-exempt
      personal income.

MAIN RISKS

      Although municipal bonds are generally designed to provide a stable and
      steady flow of in-come, their prices move inversely with changes in
      interest rates. This means the value of your investment could increase or
      decrease, which means that you could lose money. Additional risks that
      could reduce each fund's income level and share price include the
      following:

      o     Credit risk - the possibility that an issuer of bonds fails to make
            timely payments of principal or interest

      o     Call risk - as interest rates decline, bond issuers may pay off
            their loan early by buying back the bonds

      o     Governmental risk - government actions could have an adverse risk on
            municipal bond prices and could cause prices to fall

      Credit risk may vary among states based upon the economic and fiscal
      conditions of each state or the municipality within the state.

We or the funds refers to any one or more of the ten portfolios of Lord Abbett
Tax-Free Income Fund, Inc. (the "company"). Each fund operates under the
supervision of the company's Board with the advice of Lord, Abbett & Co.("Lord
Abbett"), its investment manager.

About each fund. Each fund is a professionally managed portfolio primarily
holding municipal bonds purchased with the pooled money of investors. It strives
to reach its stated goal, although as with all funds, it cannot guarantee
results.

An investment in each fund is not a bank deposit. It is not FDIC-insured or
government-endorsed. It is not a complete investment program. You could lose
money in each fund, but you also have the potential to make money.

Reasonable risk is the volatility each fund has over time, which we believe will
approximate the Lehman Brothers Current Coupon Long Index.

Municipal Bonds ("bonds") are debt securities issued by or on behalf of states,
territories and possessions of the United States and their political
subdivisions, agencies and instrumentalities which provide income free from
federal, state and/or local personal income taxes. Municipal bonds are generally
divided into two types:

o     General Obligation Bonds are secured by the full faith and credit of the
      issuer and its taxing power.

o     Revenue Bonds are payable from revenue derived from a particular facility
      or service, such as bridges, tolls or sewer services. Industrial
      development bonds are revenue bonds.

You should read this entire prospectus, including "Other Investment
Techniques," which concisely describe the other investment strategies used by
the funds and their risks.

This example is for comparison and is not a representation of the fund's actual

Management fees are payable to Lord Abbett for the fund's investment management.

12b-1 fees refer to fees incurred for activities that are primarily intended to
result in the sale of fund shares and service fees for shareholder account
service and maintenance.

Other expenses include fees paid for miscellaneous items such as transfer
agency, legal and share registration fees.

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

(1)   The annual operating expenses have been restated from fiscal year amounts
      to reflect current fees.

(2)   5.00% if shares are redeemed before 1st anniversary of purchase, declining
      to 1% before 6th anniversary and eliminated on and after 6th anniversary.

(3)   1.00% if shares are redeemed before 1st anniversary of purchase. 

(4)   Because 12b-1 distribution fees (up to: 0.35%- class A; 0.75%- classes B
      and C; and 0.20%- class P) are paid out on an on-going basis, over time
      they will increase the cost of your investment and may cost you more than
      paying other types of sales charges. Service fees under each class's 12b-1
      Plan are up to 0.25%.

(5)   Class B shares will convert to class A shares on the eighth anniversary of
      your original purchase of class B shares.

Expense example
================================================================================

This example, like that in other funds' prospectuses, assumes a $10,000 initial
investment at maximum sales charge, if any, 5% total return each year and no
changes in expenses. You pay the following expenses over the course of each
period shown if you sell your shares at the end of the period, although your
actual cost may be higher or lower. The expenses include any applicable
contingent deferred sales charges.

Share class          1 Year         3 Years          5 Years         10 Years

Class A shares        $570             $772            $991            $1,622
- --------------------------------------------------------------------------------
Class P shares        $110             $343            $595            $1,320
- --------------------------------------------------------------------------------

You would pay the following expenses on the same investment, assuming you kept
your shares.

Class A shares        $570             $772            $991            $1,622
- --------------------------------------------------------------------------------
Class P shares        $110             $343            $595            $1,320
- --------------------------------------------------------------------------------

This example is for comparison and is not a representation of the fund's actual
expenses or returns, either past or present.

Management fees are payable to Lord Abbett for the fund's investment management.

12b-1 fees refer to fees incurred for activities that are primarily intended to
result in the sale of fund shares and service fees for shareholder account
service and maintenance.

Other expenses include fees paid for miscellaneous items such as transfer
agency, legal and share registration fees.

- --------------------------------------------------------------------------------
(1)   The annual operating expenses have been restated from fiscal year amounts
      to reflect current fees.
(2)   Because 12b-1 distribution fees (up to: 0.35%- class A; and 0.20%- class
      P) are paid out on an on-going basis, over time they will increase the
      cost of your investment and may cost you more than paying other types of
      sales charges. Service fees under each class's 12b-1 Plan equal up to
      0.25%.

PAST PERFORMANCE

      The information below provides some indication of the risks of investing
      in the fund, showing changes in the fund's performance from calendar year
      to calendar year and by showing how the fund's average annual returns
      compare with those of a broad measure of market performance.

   [The following table was depicted as a line chart in the printed material]

                                "95"        14.5%

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

      The table below shows a comparison of the fund's class A average annual
      total return to that of the Lehman Municipal Bond Index. Fund returns
      assume reinvestment of dividends and distributions and payment of the
      maximum applicable front-end or deferred sales charge. All periods end on
      December 31, 1998.

(i)   The date of inception for class A shares is 12/27/94.
(ii)  Performance for the unmanaged Lehman Municipal Bond Index does not reflect
      transaction costs or management fees. This index is composed of municipal
      bonds from many different states and, therefore, it may not be valid to
      compare to a single-state municipal bond portfolio, such as this fund.
(iii) Represents total return for the period 12/31/94 - 12/31/98, to correspond

Expense example
================================================================================

This example, like that in other funds' prospectuses, assumes a $10,000 initial
investment at maximum sales charge, if any, 5% total return each year and no
changes in expenses. You pay the following expenses over the course of each
period shown if you sell your shares at the end of the period, although your
actual cost may be higher or lower. The expenses include any applicable
contingent deferred sales charges.

Share class          1 Year         3 Years          5 Years         10 Years

Class A shares        $568             $766            $981            $1,599
- --------------------------------------------------------------------------------
Class P shares        $108             $337            $585            $1,297
- --------------------------------------------------------------------------------

You would pay the following expenses on the same investment, assuming you kept
your shares.

Class A shares        $568             $766            $981            $1,599
- --------------------------------------------------------------------------------
Class P shares        $108             $337            $585            $1,297
- --------------------------------------------------------------------------------

This example is for comparison and is not a representation of the fund's actual
expenses or returns, either past or present.

Management fees are payable to Lord Abbett for the fund's investment management.

12b-1 fees refer to fees incurred for activities that are primarily intended to
result in the sale of fund shares and service fees for shareholder account
service and maintenance.

Other expenses include fees paid for miscellaneous items such as transfer
agency, legal and share registration fees.

- --------------------------------------------------------------------------------
(1)   The annual operating expenses have been restated from fiscal year amounts
      to reflect current fees.
(2)   Because 12b-1 distribution fees (up to: 0.35%- class A; and 0.20%- class
      P) are paid out on an on-going basis, over time they will increase the
      cost of your investment and may cost you more than paying other types of

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

      The table below shows a comparison of the fund's class A and C average
      annual total return to that of the Lehman Municipal Bond Index. Fund
      returns assume reinvestment of dividends and distributions and payment of
      the maximum applicable front-end or deferred sales charge. All periods end
      on December 31, 1998.

Expense example
================================================================================

This example, like that in other funds' prospectuses, assumes a $10,000 initial
investment at maximum sales charge, if any, 5% total return each year and no
changes in expenses. You pay the following expenses over the course of each
period shown if you sell your shares at the end of the period, although your
actual cost may be higher or lower. The expenses include any applicable
contingent deferred sales charges.

Share class          1 Year         3 Years          5 Years         10 Years

Class A shares        $567             $763            $976            $1,588
- --------------------------------------------------------------------------------
Class C shares        $163             $505            $871            $1,902

Class P shares        $107             $334            $579            $1,285
- --------------------------------------------------------------------------------

You would pay the following expenses on the same investment, assuming you kept
your shares.

Class A shares        $567             $763            $976            $1,588
- --------------------------------------------------------------------------------
Class C shares        $163             $505            $871            $1,902

Class P shares        $107             $334            $579            $1,285
- --------------------------------------------------------------------------------

This example is for comparison and is not a representation of the fund's actual
expenses or returns, either past or present.

Management fees are payable to Lord Abbett for the fund's investment management.

12b-1 fees refer to fees incurred for activities that are primarily intended to
result in the sale of fund shares and service fees for shareholder account
service and maintenance.

Other expenses include fees paid for miscellaneous items such as transfer
agency, legal and share registration fees.

- --------------------------------------------------------------------------------
(1)   The annual operating expenses have been restated from fiscal year amounts
      to reflect current fees.
(2)   1.00% if shares are redeemed before 1st anniversary of purchase.
(3)   Because 12b-1 distribution fees (up to: 0.35%- class A; 0.75%- classes C;
      and 0.20%- class P) are paid out on an on-going basis, over time they will
      increase the cost of your investment and may cost you more than paying
      other types of sales charges. Service fees under each class's 12b-1 Plan
      equal up to 0.25%.

This example is for comparison and is not a representation of the fund's actual
expenses or returns, either past or present.

Management fees are payable to Lord Abbett for the fund's investment management.

12b-1 fees refer to fees incurred for activities that are primarily intended to
result in the sale of fund shares and service fees for shareholder account
service and maintenance.

The 12b-1 Plan for the Washington fund will not become operative for class A
shares until the class A net assets reach $100 million.

Other expenses include fees paid for miscellaneous items such as transfer
agency, legal and share registration fees.

- --------------------------------------------------------------------------------
(1)   The annual operating expenses have been restated from fiscal year amounts
      to reflect current fees.
(2)   Because 12b-1 distribution fees (up to: 0.35%- class A; and 0.20%- class
      P) are paid out on an on-going basis, over time they will increase the
      cost of your investment and may cost you more than paying other types of
      sales charges. Service fees under each class's 12b-1 Plan equal up to
      0.25%.

PURCHASES

      This Prospectus offers four classes of shares for the National fund: class
      A, B, C and P. Three classes of shares are offered for both the California
      and New York funds: class A, C and P. Two classes of shares is offered for
      the other funds: Class A and P. Although a fund may have more than one
      class of shares, these different classes of shares represent investments
      in the same portfolio of securities but are subject to different expenses.
      Our shares are continuously offered. The offering price is based on the
      Net Asset Value ("NAV") per share next determined after we receive your
      purchase order submitted in proper form. A front-end sales charge is added
      to the NAV, in the case of the class A shares. There is no front-end sales
      charge, although there is a CDSC in the case of the class B and C shares,
      as described below.

      You should read this section carefully to determine which class of shares
      represents the best investment option for your particular situation. It

      purchased at a discount if you qualify under either of the following:

      o     Rights of Accumulation -- A Purchaser can apply the value (at public
            offering price) of the shares you already own to a new purchase of

            distributions are not included. A statement of intention can be
            back-dated 90 days. Current holdings under rights of accumulation

are valued at those quotations. Securities for with such quotations are not
available are valued at fair value under procedures approved by the Board.

      categories listed above and you redeem any of them within 24 months after
      the month in which you initially purchased them, the fund normally will
      collect a CDSC of 1%.

            withdrawals, death, disability, retirement, separation from service

Retirement Plans include employer-sponsored retirement plans under the Internal
Revenue Code, excluding Individual Retirement Accounts.

Lord Abbett Distributor LLC ("Lord Abbett Distributor") acts as agent for the
funds to work with investment professionals that buy and/or sell shares of the
funds on behalf of their clients. Generally, Lord Abbett Distributor does not

o     over $50,000 - reason for benefit payment must be received in writing. Use
      the address indicated under opening your account.

CDSC regardless of class, is not charged on shares acquired through reinvestment
of dividends or capital gains distributions and is charged on the original
purchase cost or the current market value of the shares at the time they are
being sold, which-ever is lower. In addition, repayment of loans under
Retirement Plans and 403(b) plans will constitute new sales for purposes of
assessing the CDSC.

To determine if a CDSC applies to a redemption, the fund redeems shares in the
following order:

1.    shares acquired by reinvestment of dividends and capital gains
2.    shares held for six years or more (class B) or two years or more after the
      month of purchase (class A) or one year or more (class C)
3.    shares held the longest before the sixth anniversary of their purchase
      (class B) or before the second anniversary after the month of purchase
      (class A) or before the first anniversary of their purchase (class C)

DISTRIBUTIONS AND TAXES

      Each fund pays its shareholders dividends from its net investment income,
      and distributes net capital gains that it has realized. Each fund expects
      that its dividends from investment income will be tax exempt and expects
      to pay such dividends to shareholders monthly. If a capital gain
      distribution is declared, it will be paid annually. Your distributions
      will be reinvested in your fund unless you instruct the fund to pay them
      to you in cash. There are no sales charges on reinvestments.

      The tax status of distributions are the same for all shareholders
      regardless of how long they have been in the fund or whether distributions
      are reinvested or paid in cash. In general, distributions are taxable as
      follows:

================================================================================
Federal Taxability Of Distributions

capital gains              10%                          20%
- --------------------------------------------------------------------------------

      Except in tax-advantaged accounts, any sale or exchange of fund shares may
      be a taxable event.

      Annual Information - Information concerning the tax treatment of dividends
      and other distributions will be mailed to shareholders each year. Each
      fund will also provide annually to its shareholders information regarding
      the source of dividends and distributions of capital gains paid by that
      fund. Because everyone's tax situation is unique, you should consult your
      tax adviser regarding the treatment of those distributions under the
      federal, state and local tax rules that apply to you as well as the tax
      consequences of gains or losses from the redemption or exchange of your
      shares.

Small Accounts. Our Board may authorize closing any account in which there are
fewer than 25 shares if it is in a fund's best interest to do so.

Social Security and Railroad Retirement Benefit Recipients. Shareholders
receiving social security benefits and certain railroad re-tirement benefits may
be subject to federal income tax on up to 85% of such benefits as a result of
receiving investment income, including tax-exempt income (such as
exempt-interest dividends) and other distributions paid by each fund. The tax
will be imposed on up to one-half of such benefits only when the sum of the
recipient's adjusted gross income (plus miscellaneous adjustments), tax-exempt
interest income and one-half of social security income exceeds $25,000 for
individuals ($32,000 for individuals filing a joint return). The tax will be
imposed on up to 85% of such benefits only when such sum exceeds $34,000 for
individuals ($44,000 for individuals filing a joint return).

Taxes on Transactions. The chart at left also can provide a "rule of thumb"
guide for your potential U.S. federal tax liability when selling or exchanging
fund shares. The second row, "Short-term capital gains," applies to fund shares
sold within 12 months of purchase. The third row, "Long-term capital gains,"
applies to shares held for more than 12 months.

Starting January 1, 2001, sales of securities held for more than five years will
be taxed at special lower rates.

Any gains realized on a fund's transactions in options and financial futures
will be treated as taxable long- or short-term capital gains.

SINGLE-STATE TAXABILITY OF DISTRIBUTIONS

      For All Funds - With respect to any particular state fund, exempt-interest
      dividends derived from interest income on obligations of that state or its
      political subdivisions, agencies or instrumentalities and on obligations
      of the federal government or certain other government authorities (for
      example, U.S. territories) paid to individual shareholders will, in most
      cases, be exempt from tax in that state. However, special rules, described
      below, may apply. Exempt-interest dividends may be subject to that state's
      franchise or other corporate taxes if received by a corporation subject to
      such taxes and to state and local taxes in states other than that state.
      Generally, dividends and distributions, whether received in cash or
      additional shares, derived from a state fund's other investment income and
      capital gains will be subject to state income tax. The following are
      special rules that apply to the states named below:

      Minnesota Taxes - Exempt-interest dividends paid by the Minnesota fund
      will only be exempt from Minnesota personal income tax if 95% or more of
      the exempt-interest dividends paid by the Minnesota fund come from
      Minnesota sources. The Minnesota fund intends to invest so that the 95%
      test is met each year. Generally, at least 80% of the value of the net
      assets of the Minnesota fund will be maintained in debt obligations that
      are exempt from federal income tax and Minnesota personal income tax.

      For Minnesota corporations, S corporations and partnerships holding shares
      of the fund, Minnesota fund distributions may be taken into account in
      determining the minimum fee that is imposed by the state.

      Missouri Taxes - The portion of the fund's dividends received by a
      shareholder that is exempt from Missouri personal or corporate income tax
      each year may be reduced by interest or other expenses in excess of $500
      paid or incurred to purchase or carry shares of the fund or other
      investments producing income that is exempt from Missouri income tax.
      Dividends paid by the Missouri fund generally will be exempt from Missouri
      corporate income tax to the extent that they are derived from interest on
      obligations of the State of Missouri or any of its political subdivisions
      or authorities or obligations issued by certain other government
      authorities.

      New Jersey Taxes - Exempt-interest dividends paid by the New Jersey fund
      will only be exempt from New Jersey Gross Income Tax if at least 80% of
      the interest-bearing and discount obligations held by the fund are
      obligations of the State of New Jersey or other New Jersey government
      agencies and the fund meets certain other investment and filing
      requirements. We intend to meet those requirements. As long as we meet
      those requirements, exempt-interest dividends derived from those
      obligations, capital gains distributions derived from the fund's sale or
      exchange of those obligations, and each shareholder's net gains or income
      derived from the disposition of shares of the New Jersey fund will not be
      subject to New Jersey Gross Income Tax.

      New York Taxes - Dividends derived from interest on obligations of the
      State of New York or its political subdivisions that are exempt from
      federal income tax or on obligations issued by certain other governmental
      entities paid by the New York fund will be exempt from New York City, as
      well as New York State, personal income taxes.

SALES CHARGES AND SERVICE FEES

      Sales and Service Compensation. As part of its plan for distributing
      shares, each fund and Lord Abbett Distributor pay sales and service
      compensation to Authorized Institutions that sell the fund's shares and
      service its shareholder accounts.

      Sales compensation originates from two sources: sales charges and 12b-1
      distribution fees that are paid out of each fund's assets. Service
      compensation originates from 12b-1 service fees. The 12b-1 fee rates vary
      by share class, according to the Rule 12b-1 plan adopted by each fund. The
      sales charges and 12b-1 fees paid by investors are shown in the
      class-by-class information under "Fees and Expenses" and "Purchases." The
      portion of these expenses that is paid as sales and service compensation
      to Authorized Institutions, such as your dealer, is shown in the chart at
      the end of this prospectus. The portion of such sales and service
      compensation paid to Lord Abbett Distributor is discussed under "Sales
      Activities" and "Service Activities". Sometimes we do not pay sales and
      service compensation where tracking data is not available for certain
      accounts or where the Authorized Institution waives part of the
      compensation.

      We may pay Additional Concessions to Authorized Institutions from time to
      time.

      Sales Activities. We may use 12b-1 distribution fees to pay Authorized
      Institutions to finance any activity which is primarily intended to result
      in the sale of shares. Lord Abbett Distributor uses its portion of the
      distribution fees attributable to a fund's class A and class C shares for
      activities which are primarily intended to result in the sale of such
      class A and class C shares, respectively. These activities include, but
      are not limited to, printing of prospectuses and statements of additional
      information and reports for other than existing shareholders, preparation
      and distribution of advertising and sales material, expenses of organizing
      and conducting sales seminars, Additional Concessions to Authorized
      Institutions, the cost necessary to provide distribution-related services
      or personnel, travel, office expenses, equipment and other allocable
      overhead.

      Service Activities. We may pay Rule 12b-1 service fees to Authorized
      Institutions for any activity which is primarily intended to result in
      personal service and/or the maintenance of shareholder accounts. Any
      portion of the service fees paid to Lord Abbett Distributor will be used
      to service and maintain shareholder accounts.

MANAGEMENT

      The funds' investment adviser is Lord, Abbett & Co., 767 Fifth Avenue, New
      York, NY 10153-0203. Founded in 1929, Lord Abbett manages one of the
      nation's oldest mutual fund complexes, with approximately $28 billion in
      more than 35 mutual fund portfolios and other advisory accounts. For more
      information about the services Lord Abbett provides to the funds, see the
      Statement of Additional Information.

      The fund pays Lord Abbett a monthly fee based on average daily net assets
      for each month. For the fiscal year ended September 30, 1998, the fee paid
      to Lord Abbett was at an annual rate of .50 of 1% for all funds except
      Missouri fund, Hawaii fund, and Minnesota fund. The rates for Missouri
      fund and Hawaii fund were .49 of 1% and .48 of 1%, respectively. Lord
      Abbett waived it entire fee for Minnesota fund. In addition, the fund pays
      all expenses not expressly assumed by Lord Abbett.

      Lord Abbett uses a team of portfolio managers and analysts acting together
      to manage the company's investments. Zane E. Brown, Partner and Director
      of Fixed Income of Lord Abbett, heads the team, the senior members of
      which are John R. Mousseau, Director of Municipal Bond Management, and
      Philip P. Fang, Municipal Portfolio Manager. Mr. Brown has been with Lord
      Abbett since 1992, Mr. Mousseau since 1993 and Mr. Fang since 1991.

12b-1 fees are payable regardless of expenses. The amounts payable by a fund
need not be directly related to expenses. If Lord Abbett Distributor's actual
expenses exceed the fee payable to it, a fund will not have to pay more than
that fee. If Lord Abbett Distributor's expenses are less than the fee it
receives, Lord Abbett Distributor will keep the full amount of the fee.

OTHER INVESTMENT TECHNIQUES

      This section describes some of the investment techniques that might be
      used by the funds and their risks.

      Adjusting Investment Exposure. Each fund may, but is not required to, use
      various strategies to change its investment exposure to adjust to changing
      security prices, interest rates, currency exchange rates, commodity prices
      and other factors. These strategies may involve buying or selling
      derivative instruments, such as options and futures contracts, stripped
      securities, currency exchange contracts, swap agreements, short sales of
      securities, indexed securities and rights and warrants. The fund may use
      these transactions to change the risk and return characteristics of each
      fund's portfolio. If we judge market conditions incorrectly or use a
      strategy that does not correlate well with the fund's investments, it
      could result in a loss, even if we intended to lessen risk or enhance
      returns. These transactions may involve a small investment of cash
      compared to the magnitude of the risk assumed and could produce
      disproportionate gains or losses. Also, these strategies could result in
      losses if the counterparty to a transaction does not perform as promised.

      Borrowing. Each fund may borrow from banks. If a fund borrows money, its
      share price may be subject to greater fluctuation until the borrowing is
      paid off. each underlying fund may borrow only for temporary or emergency
      purposes, and not in an amount exceeding 331/3% of its total assets.

      Concentration. No fund intends to invest more than 25% of its total assets
      in any industry, except that each fund may, subject to the limits referred
      to in Diversification, Private Activity Bonds and with respect to
      temporary taxable investments under "Main Risks," invest more than 25% of
      such assets in a combination of U.S. Government securities and in
      tax-exempt securities, including tax-exempt revenue bonds whether or not
      the users of any facilities financed by such bonds are in the same
      industry. Where nongovernmental users are in the same industry, there may
      be additional risk to a fund in the event of an economic downturn in such
      industry, which may result generally in a lowered ability of such users to
      make payments on their obligations. Electric utility and health care are
      typical, but not all inclusive of, the industries in which this 25% may be
      exceeded. The former is relatively stable but subject to rate regulation
      vagaries. The latter suffers from two main problems affordability and
      access. Tax-exempt securities issued by governments or political
      subdivisions of governments are not considered part of any "industry."

      Diversification. National fund is a diversified fund, which means that
      with respect to 75% of its total assets, it will not purchase a security
      if, as a result, more than 5% of the fund's total assets would be invested
      in securities of a single issuer or the fund would hold more than 10% of
      the outstanding voting securities of the issuer. Each fund (except
      National fund) is a nondiversified mutual fund. This means that the fund
      may invest a greater portion of its assets in, and own a greater amount of
      the voting securities of, a single company than a diversified fund. This
      may expose the fund to greater risk.

      Illiquid Securities. These securities include those that are not traded on
      the open market or that trade irregularly or in very low volume. They may
      be difficult or impossible to sell at the time and price the fund would
      like. Each underlying fund may invest up to 15% of its assets in illiquid
      securities.

      Investment Grade Debt Securities. These are debt securities which are
      rated in one of 


20 / For More Information
<PAGE>

      the four highest grades assigned by Moody's Investors Service, Inc.,
      Standard & Poor's Ratings Services or Fitch Investors Service, or are
      unrated but determined by Lord Abbett to be equivalent in quality.

      Options and Financial Futures Transactions. Each fund may deal in options
      on securities, and securities indices, and financial futures transactions,
      including options on financial futures to increase or decrease its
      exposure to changing securities prices or interest rates or for bona fide
      hedging purposes. Each fund may write (sell) covered call options and
      secured put options on up to 25% of its net assets and may purchase put
      and call options and purchase and sell futures contracts provided that no
      more than 5% of its net assets (at the time of purchase) may be invested
      in premiums on such options and initial margin deposits on such futures
      contracts.

      In addition the use of options and financial futures transactions to
      achieve a funds' investment objective could result in a loss due to
      unanticipated market conditions and could increase the volatility of the
      fund. These transactions may involve a small investment of cash relative
      to the risks assumed.

      Private Activity Bonds. Each fund may invest up to 20% of its net assets
      (less any amount invested in the temporary taxable investments described
      under "Main Risks") in private activity bonds. A fund's dividends derived
      from interest on such bonds would be considered a preference item for
      purposes of the computation of the alternative minimum tax. A fund's
      dividends derived from such interest may increase the alternative minimum
      tax liability of corporate shareholders who are subject to that tax based
      on the excess of their adjusted current earnings over their taxable
      income.

      Residual Bonds. Each fund may invest up to 20% of its net assets in
      residual interest bonds ("RIBs") to enhance and increase portfolio
      duration. None of the funds invested more than 16% of its net assets in
      RIBs at any time during the fiscal year ended September 30, 1998. A RIB,
      sometimes referred to as an inverse floater,is a debt instrument with a
      floating or variable interest rate that moves in the opposite direction of
      the interest rate on another specific fixed-rate security ("specific
      fixed-rate security"). Changes in the interest rate on the specific
      fixed-rate security inversely affect the residual interest rate paid on
      the RIB, with the result that when interest rates rise, RIBs' interest
      payments are lowered and their value falls faster than securities similar
      to the specific fixed-rate security. In an effort to mitigate this risk,
      each fund purchases fixed-rate bonds which are less volatile. When
      interest rates fall, not only do RIBs provide interest payments that are
      higher than securities similar to the specific fixed-rate security, but
      their values also rise faster than securities similar to the specific
      fixed-rate security.

      U.S. Government Securities. These are obligations issued or guaranteed by
      the U.S. Government, its agencies or instrumentalities.

      When-Issued Municipal Bonds. Each fund may purchase new issues of
      municipal bonds, which are generally offered on a when-issued basis, with
      delivery and payment ("settlement") normally taking place approximately
      one month after the purchase date. However, the payment obligation and the
      interest rate to be received by a fund are each fixed on the purchase
      date. During the period between purchase and settlement, each fund's
      assets consisting of cash and/or high-grade marketable debt securities,
      marked to market daily, of an amount sufficient to make payment at
      settlement will be segregated at our custodian. There is a risk that
      market yields available at settlement may be higher than yields obtained
      on the purchase date, which could result in depreciation of value. While
      we may sell when-issued securities prior to settlement, we intend to
      actually acquire such securities unless a sale appears desirable for
      investment reasons.

GLOSSARY OF SHADED TERMS

      Additional Concessions. Lord Abbett Distributor may, for specified
      periods, allow dealers to retain the full sales charge for sales of shares
      or may pay an additional concession to a dealer who sells a minimum dollar
      amount of our shares and/or shares of other Lord Abbett-sponsored funds.
      In some instances, such additional concessions will be offered only to
      certain dealers expected to sell significant amounts of shares. Additional
      payments may be paid from Lord Abbett Distributor's own resources or from
      distribution fees received from a fund and will be made in the form of
      cash or, if permitted, non-cash payments. The non-cash payments will
      include business seminars at Lord Abbett's headquarters or other
      locations, including meals and entertainment, or the receipt of
      merchandise. The cash payments may include payment of various business
      expenses of the dealer.

      In selecting dealers to execute portfolio transactions for a fund's
      portfolio, if two or more dealers are considered capable of obtaining best
      execution, we may prefer the dealer who has sold our shares and/or shares
      of other Lord Abbett-sponsored funds.

      Authorized Institutions. Institutions and persons permitted by law to
      receive service and/or distribution fees under a Rule 12b-1 plan are
      "authorized institutions." Lord Abbett Distributor is an Authorized
      Institution.

      Eligible Fund. An Eligible Fund is any Lord Abbett-sponsored fund except
      for certain tax-free, single-state funds where the exchanging shareholder
      is a resident of a state in which such a fund is not offered for sale;
      Lord Abbett Equity Fund; Lord Abbett Series Fund; Lord Abbett U.S.
      Government Securities Money Market Fund ("GSMMF") (except for holdings in
      GSMMF which are attributable to any shares exchanged from the Lord Abbett
      family of funds). An Eligible Fund also is any Authorized Institution's
      affiliated money market fund satisfying Lord Abbett Distributor as to
      certain omnibus account and other criteria.

      Eligible Mandatory Distributions. If class B shares represent a part of an
      individual's total IRA or 403(b) investment, the CDSC will be waived only
      for that part of a mandatory distribution which bears the same relation to
      the entire mandatory distribution as the B share investment bears to the
      total investment.

      Legal Capacity. With respect to a redemption request, if (for example) the
      request is on behalf of the estate of a deceased shareholder, John W. Doe,
      by a person (Robert A. Doe) who has the legal capacity to act for the
      estate of the deceased shareholder because he is the executor of the
      estate, then the request must be executed as follows: Robert A.Doe,
      Executor of the Estate of John W. Doe. That signature using that capacity
      must be guaranteed by an Eligible Guarantor.

      Similarly, if (for example) the redemption request is on behalf of the ABC
      Corporation by a person (Mary B. Doe) that has the legal capacity to act
      on behalf of this corporation, because she is the President of the
      corporation, then the request must be executed as follows: ABC Corporation
      by Mary B.Doe, President. That signature using that capacity must be
      guaranteed by an Eligible Guarantor.

      Mutual Fund Advisory Program. Certain unaffiliated authorized brokers,
      dealers, registered investment advisers or other financial institutions
      who either (a) have an arrangement with Lord Abbett Distributor in
      accordance with certain standards approved by Lord Abbett Distributor,
      providing specifically for the use of our shares (and sometimes providing
      for acceptance of orders for such shares on our behalf) in particular
      investment products made available for a fee to clients of such brokers,
      dealers, registered investment advisers and other financial institutions,
      or (b) who charge an advisory, con-

      accounts or the accounts of their clients.

      Purchaser. The term "purchaser" includes: (i) an individual, (ii) an
      individual and his or her spouse and children under the age of 21, and
      (iii) a trustee or other fiduciary purchasing shares for a single trust
      estate or single fiduciary account (including a pension, profit-sharing,
      or other employee benefit trust qualified under Section 401 of the
      Internal Revenue Code - more than one qualified employee benefit trust of
      a single employer, including its consolidated subsidiaries, may be
      considered a single trust, as may qualified plans of multiple employers
      registered in the name of a single bank trustee as one account), although
      more than one beneficiary is involved.

      Special Retirement Wrap Program. A program sponsored by an authorized
      institution showing one or more characteristics distinguishing it, in the
      opinion of Lord Abbett Distributor from a mutual Fund Advisory Program.
      Such characteristics include, among other things, the fact that an
      authorized institution does not charge its clients any fee of a consulting
      or advisory nature that is economically equivalent to the distribution fee
      under the class A 12b-1 Plan and the fact that the program relates to
      participant-directed Retirement Plans.

RECENT PERFORMANCE

      During the past fiscal year, economic and political uncertainties abroad
      created concern regarding the domestic economy and, investors moved from
      lower-rated fixed income investments into higher-quality bonds. Because we
      focus on high-quality municipal issues, the funds' net asset values
      increased.

      Throughout the fiscal year, the funds held some prerefunded bonds. In an
      environment of falling rates, many issuers prerefunded existing,
      higher-coupon bonds. When an issuer prerefunds bonds, the proceeds from a
      newly issued lower-yielding bonds are used to buy Treasury securities.
      These Treasury securities are held to pay interest and principal on the
      older, higher-coupon bonds on the first call date. (The call date is a
      date upon which an issuer may redeem a bond.) When a bond becomes a strong
      prerefunding candidate, it trades off its lower yield-to-call rather than
      its higher yield-to-maturity. As a result, it appreciates in price due to
      the closer maturity date (the call date) and the increase in the
      underlying credit quality (through the use of the Treasury securities).

      In the spring, Long Island Power Authority ("LIPA") brought to market the
      largest municipal bond issue ($3 billion) in history. Before this
      offering, many portfolio managers raised cash by selling bonds to raise
      the cash needed to invest in the LIPA issue. We correctly anticipated that
      managers would need to liquidate some of their high quality bonds to make
      room for LIPA, and purchased several issues at prices which we believe
      were below their true value.

Year 2000 Issues. Each fund could be adversely affected if the computers used by
each fund and their service providers do not properly process and calculate
date-related information from and after January 1, 2000.

While year 2000-related computer problems could have a negative effect on each
fund, Lord Abbett is working to avoid such problems and has assurances from each
fund's service providers that they are taking similar steps. However, because
the problem is unprecedented and efforts to identify and fix it are on-going, we
don't know whether these efforts will be successful. Accordingly, each fund may
be adversely affected.

PUERTO RICO - Risk Factors (Applicable to each fund)

      Each fund may invest in bonds issued by the Commonwealth of Puerto Rico
      and its instrumentalities. The economy of Puerto Rico is dominated by the
      manufacturing and service sectors. It is closely integrated, through
      extensive trade, with that of the mainland United States, and its economic
      health is closely tied to the price of oil and the state of the U.S.
      economy. Although its unemployment rate has steadily declined in recent
      years, Puerto Rico's unemployment rate continues to exceed the U.S.
      average.

      Recently, Puerto Rico's economy has experienced significant growth.
      Continued growth will depend on several factors, including the state of
      the U.S. economy, the relative stability of the price of oil and borrowing
      costs.

      deduction of the maximum initial sales charge of 4.75% applicable to class
      A shares, with all dividends and distributions reinvested for the periods
      shown ending September 30, 1998 using the SEC-required uniform method to
      compute total return. The class A share inception date is 4/2/84.

CALIFORNIA BONDS - Risk Factors

      Various constitutional and statutory provisions may affect the ability of
      issuers of California municipal bonds to meet their financial obligations.
      Decreases in State and local revenues due to such provisions may reduce
      the ability of California issuers to satisfy their obligations.
      California's recovery from the early 1990s recession, in which the
      construction, manufacturing and financial services industries were
      adversely affected, is now nearly complete. Unemployment levels, although
      they exceed the national average, have continued to decrease. In addition,
      while in the early 1990s the State had depended on external borrowing,
      including borrowing past the end of a fiscal year, to meet its cash needs,
      the State has not had to resort to such cross-year borrowing after the
      1994-95 fiscal year. The substantial budget deficit that was accumulated
      by the State during the recession, which contributed to a significant
      reduction in the State's cash resources available to pay its ongoing
      obligations, has been eliminated.

(2)   Performance for the unmanaged Lehman Municipal Bond Index does not reflect
      transaction costs, management fees or sales charges. This index is
      composed of municipal bonds from many different states and, therefore, it
      may not be valid to compare to a single-state municipal bond portfolio,
      such as this fund.

(4)   This shows total return which is the percent change in value, after
      deduction of the maximum initial sales charge of 4.75% applicable to class
      A shares, with all dividends and distributions reinvested for the periods
      shown ending September 30, 1998 using the SEC-required uniform method to
      compute total return. The class A shares inception date is 9/3/85.
(5)   The class C shares were first offered on 7/15/96. Performance is at net
      asset value.

CONNECTICUT BONDS - Risk Factors

      Connecticut's economy, while traditionally concentrated in the
      manufacturing sector, has broadened in recent years with growth in
      service, finance, trade and utilities. The economy continues to improve
      and recover from its recession in the early 1990s. The average per capita
      income of Connecticut remains among the highest in the nation.
      Connecticut's financial performance has also improved in recent years. As
      of June 30, 1997, the State has provided in full for payment on economic
      recovery notes issued to fund its accumulated General Fund deficit as of
      1991, and the balance in the budget reserve fund from unappropriated
      surplus was $240.97 million. The State's high level of tax-supported debt
      remains a concern, however, as it poses a relatively significant burden on
      the State's revenue base.

HAWAII BONDS - Risk Factors

      Hawaii has exhibited poor economic performance and modest personal income
      growth since the early 1990s and its economic recovery continues to be
      slow and uneven. Hawaii's economy is concentrated in retail trade and
      tourism and also includes constructions, agriculture and military
      operations. Tourism is a major factor in the economy, and has been harmed
      by recent financial and economic downturns in Southeast Asia. Construction
      activity has also declined. Agriculture, dominated by pineapple and sugar
      production, has experienced increased foreign competition. Economic
      diversification projects are under way, including expansion of
      containerized port facilities, aquaculture and other agricultural
      products, but these projects have not yet had any significant positive
      effects on the State's overall economy.

      Most government activities, including activities administered in other
      states on a municipal or county level, such as public education, public
      hospitals and public welfare, are the State's responsibility. This
      contributes to the high level of State debt obligations. Revenue is
      derived primarily from the general excise taxes and individual and
      corporate tax, and tax revenues have declined.

      Hawaii's county governments (the only units of local government in the
      State) may issue government obligation bonds, which obligations have
      further increased, and may continue to increase in the future, the State's
      high level of overall municipal debt.

MINNESOTA BONDS - Risk Factors

      Minnesota's significant public debt includes the State's general
      obligation debt, as well as university and other agency debt that is not
      an obligation of the State. The State relies heavily on individual, sales
      and corporate income taxes for revenues, all of which are sensitive to
      economic conditions and could be adversely affected by an economic
      downturn.

MISSOURI BONDS - Risk Factors

      Economic reversals in either Kansas City or St. Louis metropolitan areas,
      whose Missouri portions together contain a significant portion of the
      State's population, would have a major impact on the State's overall
      economic condition. Missouri's unemployment levels have steadily declined
      and have remained below the national average since 1991, as employment
      levels have continued to grow. Changes in military appropriations, which
      play an important role in the State's economy, could adversely affect
      unemployment rates. As discussed in the Statement of Additional
      Information, payment on Missouri municipal bonds could be adversely
      affected by certain provisions of the Constitution of Missouri.

NEW JERSEY BONDS - Risk Factors

      The State's economy has been steadily improving since the recent recession
      as shown by employment gains and growth in other economic activity. New
      Jersey is a major recipient of federal assistance. Hence, a decrease in
      federal financial assistance may adversely affect New Jersey's financial
      condition. In an attempt to ensure that local governmental entities remain
      on a sound financial basis. State law restricts total appropriations
      increases to 5% annually for such entities, with certain exceptions.
      Statutory or legislative restrictions of such character may adversely
      affect a municipality's or any other bond-issuing authority's ability to
      repay its obligations.

(2)   Performance for the unmanaged Lehman Municipal Bond Index does not reflect
      transaction costs, management fees or sales charges. This index is
      composed of municipal bonds from many different states and, therefore, it
      may not be valid to compare to a single-state municipal bond portfolio,
      such as this fund.

      deduction of the maximum initial sales charge of 4.75% applicable to class
      A shares, with all dividends and distributions reinvested for the periods
      shown ending September 30, 1998 using the SEC-required uniform method to
      compute total return. The class A share inception date is 1/2/91.

NEW YORK BONDS - Risk Factors

      New York State has recorded balanced budgets on a cash basis for its last
      six fiscal years. While the State budget for fiscal 1998-99 again calls
      for a balanced budget, gaps between actual revenues and expenditures may
      arise in the current year and in future fiscal years. Because the State,
      New York City, the State's other political subdivisions and the State
      Authorities, all of which borrow money, are or are perceived in the
      marketplace to be financially interdependent, financial difficulty
      experienced by one can adversely affect the market value and marketability
      of obligations issued by others. The State's credit is presently involved
      with the indebtedness of the Authorities because of the State's guarantee
      or other support. This indebtedness is substantial. The Authorities are
      likely to require further financial assistance from the State. During the
      last several fiscal years, New York City has been required to take actions
      to close substantial budget gaps in order to maintain balanced budgets.
      Similar shortfalls and budget gaps have been predicted for future years
      and will require further action by the City's government.

TEXAS BONDS - Risk Factors

      Texas' economy recovered from the recession that began in the mid-1980s
      after a collapse in oil prices. The economy has become more stable due to
      increased diversification, with the oil and gas industry diminishing in
      relative importance while service-producing sectors are the major source
      of job growth. The biennial all funds budget for the State did not require
      increasing state taxes, primarily due to a healthy state economy, a $2.0
      billion surplus from the previous biennium, and a legislative leadership
      mandate to "hold-the-line" on spending growth. The State has had a
      positive balance in its general revenue fund for ten consecutive years.
      Although we anticipate that most of the bonds in the Texas Fund will be
      revenue obligations or general obligations of local governments or
      authorities, any circumstances that affect the market value of these other
      bonds held by the Texas Fund, either directly or indirectly, as a result
      of a dependency of local governments and other authorities upon State aid
      and reimbursement programs.

WASHINGTON BONDS - Risk Factors

      The State of Washington's economy includes manufacturing and service
      industries as well as agricultural and timber production. The State's
      leading export industries are aerospace, forest products, agriculture and
      timber production. The Boeing Company, one of the world's largest
      aerospace firms, is the State's largest employer and as such has a
      significant impact, in terms of production, employment and labor earnings,
      on the State's economy. Continued declines in the forest products industry
      are expected in the future, and although a decrease in employment in this
      area is also expected, the impact is not expected to significantly affect
      the State's overall economic performance.

      State law requires a balanced budget. The Governor has a statutory
      responsibility to reduce expenditures across the board to avoid any cash
      deficit at the end of a biennium.

      transaction costs, management fees or sales charges. This index is
      composed of municipal bonds from many different states and, therefore, it
      may not be valid to compare to a single-state municipal bond portfolio,
      such as this fund.

(1)   The service fee for class A shares is paid quarterly and for class A
      shares may not exceed 0.15% for shares sold prior to: June 1, 1990 for the
      National fund; January 1, 1993 for the Hawaii fund; the first day of the
      calendar quarter subsequent to the Minnesota fund's net assets reaching
      $100 million; July 1, 1992 for the New Jersey fund; June 1, 1990 for the
      New York fund; June 1, 1990 for the Texas fund; and the first day of the
      calendar quarter subsequent to the Washington fund's net assets reaching
      $100 million. The first year's service fee on class B and C shares is paid
      at the time of sale.
(2)   Reallowance/concession percentages and service fee percentages are
      calculated from different amounts, and therefore may not equal total
      compensation percentages if combined using simple addition. Additional
      Concessions may be paid to Authorized Institutions, such as your dealer,
      from time to time.
(3)   Concessions are paid at the time of sale on all class A shares sold during
      any 12-month period starting from the day of the first net asset value
      sale. With respect to (a) class A share purchases at $1 million or more,
      sales qualifying at such level under rights of accumulation and statement
      of intention privileges are included and (b) for Special Retirement Wrap
      Programs, only new sales are eligible and exchanges into the fund are
      excluded.
(4)   With respect to class B and C shares, 0.25% and 0.90%, respectively, of
      the average annual net asset value of such shares outstanding during the
      quarter (including distribution reinvestment shares after the first
      anniversary of their issuance) is paid to Authorized Institutions, such as
      your dealer. These fees are paid quarterly in arrears.

LORD ABBETT

Statement of Additional Information                             February 1, 1999
- --------------------------------------------------------------------------------

                     Lord Abbett Tax-Free Income Fund, Inc.

This Statement of Additional Information is not a Prospectus. A Prospectus may
be obtained from your securities dealer or from Lord Abbett Distributor LLC
("Lord Abbett Distributor"), The General Motors Building, 767 Fifth Avenue, New
York, New York 10153-0203. This Statement relates to, and should be read in
conjunction with, the Prospectus dated February 1, 1999.

Lord Abbett Tax-Free Income Fund, Inc. (referred to as the "Company") was
incorporated under Maryland law on December 27, 1983. Each Portfolio of the
Company is sometimes referred to as a "Fund" or "we". Each Fund, except for
National Fund, is an open-end non-diversified management investment company.
National fund is diversified. Our Board of Directors has authority to create and
classify shares of common stock in separate funds, without further action by
shareholders. To date, 40,000,000 shares of each of the Connecticut, Hawaii,
Minnesota, Missouri, Texas and Washington Funds, 80,000,000 shares of New Jersey
Fund, 100,000,000 shares of each of California and New York Funds, and
120,000,000 shares of the National Fund have been authorized. The National Fund
consists of three classes of shares (A, B and C). Both the New York and
California Funds consist of two classes (A and C). All other funds offer a
single class of shares: Class A shares. The Board of Directors will allocate
these authorized shares among the classes of each Fund from time to time. All
shares have equal noncumulative voting rights and equal rights with respect to
dividends, assets and liquidation, except for certain class-specific expenses.
They are fully paid and nonassessable when issued and have no preemptive or
conversion rights. Although no present plans exist to do so, further funds may
be added in the future. The Investment Company Act of 1940, as amended (the
"Act"), requires that where more than one fund exists, each fund must be
preferred over all other funds in respect of assets specifically allocated to
such fund.

Rule 18f-2 under the Act provides that any matter required to be submitted, by
the provisions of the Act or applicable state law, or otherwise, to the holders
of the outstanding voting securities of an investment company such as the
Company shall not be deemed to have been effectively acted upon unless approved
by the holders of a majority of the outstanding shares of each class or fund
affected by such matter. Rule 18f-2 further provides that a class or fund shall
be deemed to be affected by a matter unless the interests of each class or fund
in the matter are substantially identical or the matter does not affect any
interest of such class or fund. However, the Rule exempts the selection of
independent public accountants, the approval of principal distribution contracts
and the election of directors from the separate voting requirements of the Rule.

Shareholder inquiries should be made by writing directly to the Company or by
calling 800-821-5129. The 1998 Annual Shareholder Report is available, without
charge, upon request by calling that number. In addition, you can make inquiries
through your dealer.

                        Investment Objective and Policies

Each Fund will not change its investment objective mentioned in the prospectus
of the following Fundamental Investment Restrictions without shareholder
approval. If a Fund determines that its objective can best be achieved by a
change in any non-fundamental investment policy, strategy or restriction, it may
make such change without shareholder approval by disclosing it in the Prospectus
or Statement of Additional Information.

Fundamental Investment Restrictions. Each Fund may not: (1) borrow money (except
that (i) each Fund may borrow from banks (as defined in the Act) in amounts up
to 33 1/3% of its total assets (including the amount borrowed), (ii) each Fund
may borrow up to an additional 5% of its total assets for temporary purposes,
(iii) each Fund may obtain such short-term credit as may be necessary for the
clearance of purchases and sales of portfolio securities and (iv) each Fund may
purchase securities on margin to the extent permitted by applicable law); (2)
pledge its assets (other than to secure such borrowings or to the extent
permitted by each Fund' investment policies as permitted by applicable law); (3)
engage in the underwriting of securities except pursuant to a merger or
acquisition or to the extent that, in connection with the disposition of its
portfolio securities, it may be deemed to be an underwriter under federal
securities laws; (4) make loans to other persons, except that the acquisition of
bonds, debentures or other corporate debt securities and investment in
government obligations, commercial paper, pass-through instruments, certificates
of deposit, bankers acceptances, repurchase agreements or any similar
instruments shall not be subject to this limitation, and except further that
each Fund may lend its portfolio securities, provided that the lending of
portfolio securities may be made only in accordance with applicable law; (5) buy
or sell real estate (except that each Fund may invest in securities directly or
indirectly secured by real estate or interests therein or issued by companies
which invest in real estate or interests therein), commodities or commodity
contracts (except to the extent each Fund may do so in accordance with
applicable law and without registering as a commodity pool operator under the
Commodity Exchange Act as, for example, with futures contracts); (6) with
respect to 75% of the gross assets of the National Fund, buy securities of one
issuer representing more than (i) 5% of the Fund' gross assets, except
securities issued or guaranteed by the U.S. Government, its agencies or
instrumentalities or (ii) 10% of the voting securities of such issuer; (7)
invest more than 25% of its assets, taken at market value, in the securities of
issuers in any particular industry (excluding tax-exempt securities such as
tax-exempt securities financing facilities in the same industry or issued by
nongovernmental users and securities of the U.S. Government, its agencies and
instrumentalities); or (8) issue senior securities to the extent such issuance
would violate applicable law.

With respect to the restrictions mentioned herein, compliance therewith will not
be affected by change in the market value of portfolio securities but will be
determined at the time of purchase or sale of such securities.

Non-Fundamental Investment Restrictions. In addition to the investment
restrictions above which cannot be changed without shareholder approval, we also
are subject to the following non-fundamental investment policies which may be
changed by the Board of Directors without shareholder approval. Each Fund may
not: (1) borrow in excess of 33 1/3% of its total assets (including the amount
borrowed), and then only as a temporary measure for extraordinary or emergency
purposes; (2) make short sales of securities or maintain a short position except
to the extent permitted by applicable law; (3) invest knowingly more than 15% of
its net assets (at the time of investment) in illiquid securities, except for
securities qualifying for resale under Rule 144A of the Securities Act of 1933
deemed to be liquid by the Board of Directors; (4) invest in securities of other
investment companies, except as permitted by applicable law; (5) invest in
securities of issuers which, together with predecessors, have a record of less
than three years of continuous operation, if more than 5% of the Fund's total
assets would be invested in such securities (this restriction shall not apply to
mortgaged-backed securities, asset-backed securities or obligations issued or
guaranteed by the U. S. government, its agencies or instrumentalities); (6) hold
securities of any issuer if more than 1/2 of 1% of the issuer's securities are
owned beneficially by one or more of the Company's officers or directors or by
one or more partners or members of each Fund's underwriter or investment adviser
if these owners in the aggregate own beneficially more than 5% of the securities
of such issuer; (7) invest in warrants if, at the time of acquisition, its
investment in warrants, valued at the lower of cost or market, would exceed 5%
of each Fund's total assets (included within such limitation, but not to exceed
2% of the Fund's total assets, are warrants which are not listed on the New York
or American Stock Exchange or a major foreign exchange; (8) invest in real
estate limited partnership interests or interests in oil, gas or other mineral
leases, or exploration or development programs, except that each Fund may invest
in securities issued by companies that engage in oil, gas or other mineral
exploration or development activities; (9) write, purchase or sell puts, calls,
straddles, spreads or combinations thereof, except to the extent permitted in
the Fund's prospectus and statement of additional information, as they may be
amended from time to time or (10) buy from or sell to any of the Company's
officers, directors, employees, or each Fund's


                                       2

investment adviser or any of the investment advisor's officers, directors,
partners or employees, any securities other than shares of the Fund's common
stock.

With respect to each Fund other than the National Fund, there is no fundamental
policy or restriction with respect to diversification, but each Fund will be
required to meet the diversification rules under Subchapter M of the Internal
Revenue Code.

While each of the Series may take short-term gains if deemed appropriate,
normally the Series will hold securities in order to realize interest income
exempt from federal income tax and, where applicable, its state's personal
income tax, consistent with reasonable risk. For the year ended September 30,
1997, the portfolio turnover rates for the National, New York, California,
Texas, New Jersey, Connecticut, Missouri, Hawaii, Washington and Minnesota
Series were 304.15%, 64.63%, 187.26%, 143.78%, 118.38%, 61.06%, 72.89%, 52.65%,
141.56% and 40.65%, respectively.

The liquidity of a Rule 144A security will be a determination of fact for which
the Board of Directors is ultimately responsible. However, the Directors may
delegate the day-to-day function of such determinations to Lord, Abbett & Co.
("Lord Abbett"), subject to the Directors' oversight. Examples of factors which
the Directors may take into account with respect to a Rule 144A security include
the frequency of trades and quotes for the security, the number of dealers
willing to purchase or sell the security and the number of other potential
purchasers, dealer undertakings to make a market in the security and the nature
of the security and of the marketplace (e.g., the time period needed to dispose
of the security, the method of soliciting offers and the mechanics of transfer).
Rule 144A securities may be considered illiquid in certain circumstances to the
extent necessary to comply with applicable state law requirements.

Municipal Bonds

In general, municipal bonds are debt obligations issued by or on behalf of
states, territories and possessions of the United States and the District of
Columbia and Puerto Rico and by their political subdivisions, agencies and
instrumentalities. Municipal bonds are issued to obtain funds for various public
purposes, including the construction of bridges, highways, housing, hospitals,
mass transportation, schools, streets and water and sewer works. They may be
used to refund outstanding obligations, to obtain funds for general operating
expenses, or to obtain funds to lend to other public institutions and facilities
and in anticipation of the receipt of revenue or the issuance of other
obligations. In addition, the term "municipal bonds" includes certain types of
"private activity" bonds including industrial development bonds issued by public
authorities to obtain funds to provide privately-operated housing facilities,
sports facilities, convention or trade show facilities, airport, mass transit,
port or parking facilities, air or water pollution control facilities and
certain facilities for water supply, gas, electricity, or sewerage or solid
waste disposal. Under the Tax Reform Act of 1986, as amended, substantial
limitations have been imposed on new issues of municipal bonds to finance
privately-operated facilities. The interest on municipal bonds generally is
excludable from gross income for federal income tax purposes of most investors.
The two principal classifications of municipal bonds are "general obligation"
and limited obligation or "revenue bonds." General obligation bonds are secured
by the pledge of the faith, credit and taxing power of the municipality for the
payment of principal and interest. The taxes or special assessments that can be
levied for the payment of debt service may be limited or unlimited as to rate or
amount. Revenue bonds are payable only from the revenues derived from a
particular facility or class of facilities or, in some cases, from the proceeds
of a special excise or other specific revenue source. "Private activity" bonds,
including industrial development bonds are, in most cases, revenue bonds and
generally do not constitute the pledge of the faith, credit or taxing power of
the municipality. The credit quality of such municipal bonds usually is directly
related to the credit standing of the user of the facilities. There are
variations in the security of municipal bonds, both within a particular
classification and between classifications, depending on numerous factors.

The yields on municipal bonds are dependent on a variety of factors, including
general market conditions, supply and demand, general conditions of the
municipal bond market, size of a particular offering, the maturity of the
obligation and the rating of the issue. The ratings of Moody's Investors
Service, Inc. ("Moody's") and Standard & Poor's Ratings Services ("Standard &
Poor's") and Fitch Investors Service ("Fitch") represent their opinions as to
the quality of the municipal bonds which they undertake to rate. It should be
emphasized, however, that such ratings are general and are not absolute
standards of quality. Consequently, municipal bonds with the same maturity,
coupon and rating may have different yields when purchased in the open market,
while municipal bonds of the same maturity and coupon with different ratings may
have the same yield.

Description of Four Highest Municipal Bond Ratings

Moody's describes its four highest ratings for municipal bonds as follows:

Aaa   Bonds that 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 by an
      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 that are rated Aa are judged to be of high quality by all standards.
      Together with the Aaa group they comprise what are generally known as high
      grade bonds. They are rated lower than the best bonds because margins of
      protection may not be as large as in Aaa securities or fluctuation of
      protective elements may be of greater amplitude or there may be other
      elements present that make the 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 as upper medium grade obligations. Factors giving
      security to principal and interest are considered adequate, but elements
      may be present which suggest a susceptibility to impairment some time in
      the future.

Baa   Bonds that are rated Baa are considered as 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.

Standard & Poor's describes its four highest ratings for municipal bonds as
follows:

AAA   An obligation rated AAA has the highest rating assigned by Standard &
      Poor's. The obligor's capacity to meet its financial commitment on the
      obligation is extremely strong.

AA    An obligation rated AA differs from the highest rated obligations only in
      small degree. The obligor's capacity to meet its financial commitment on
      the obligation is very strong.

A     An obligation rated A is somewhat more susceptible to the adverse effects
      of changes in circumstances and economic conditions than obligations in
      higher-rated categories. However, the obligor's capacity to meet its
      financial commitment on the obligation is still strong.

BBB   An obligation rated BBB exhibits adequate protection parameters. However,
      adverse economic conditions are changing circumstances are more likely to
      lead to a weakened capacity of the obligor to meet its financial
      commitment on the obligation."

Fitch describes its four highest ratings for municipal bonds as follows:

AAA   Highest credit quality. 'AAA' ratings denote the lowest expectation of
      credit risk. They are assigned only in case of exceptionally strong
      capacity for timely payment of financial commitments. This capacity is
      highly unlikely to be adversely affected by foreseeable events.

AA    Very high credit quality. 'AA' ratings denote a very low expectation of
      credit risk. They indicate very strong capacity for timely payment of
      financial commitments. This capacity is not significantly vulnerable to
      foreseeable events.

A     High credit quality. 'A' ratings denote a low expectation of credit risk.
      The capacity for timely payment of financial commitments is considered
      strong. This capacity may, nevertheless, be more vulnerable to changes in
      circumstances or in economic conditions than is the case for higher
      ratings.


                                       4
<PAGE>

BBB   Good credit quality. 'BBB' ratings indicate that there is currently a low
      expectation of credit risk. The capacity for timely payment of financial
      commitments is considered adequate, but adverse changes in circumstances
      and in economic conditions are more likely to impair this capacity. This
      is the lowest investment-grade category.

Options and Financial Futures Transactions

General. Each Fund may engage in options and financial futures transactions in
accordance with its investment objective and policies. Although none of the Fund
are currently employing such options and financial futures transactions, and
have no current intention of doing so, each may engage in such transactions in
the future if it appears advantageous to the Fund to do so, in order to hedge
against the effects of fluctuating interest rates and other market conditions or
to stabilize the value of the Fund' assets. The use of options and financial
futures, and possible benefits and attendant risks, are discussed below, along
with information concerning certain other investment policies and techniques.

Financial Futures Contracts. Each Fund may enter into financial futures
contracts for the future delivery of a financial instrument, such as a security
or the cash value of a securities index. This investment technique is designed
primarily to hedge (i.e., protect) against anticipated future changes in
interest rates or market conditions which otherwise might adversely affect the
value of securities which a Fund holds or intends to purchase. A "sale" of a
futures contract means the undertaking of a contractual obligation to deliver
the securities or the cash value of an index called for by the contract at a
specified price during a specified delivery period. A "purchase" of a futures
contract means the undertaking of a contractual obligation to acquire the
securities or cash value of an index at a specified price during a specified
delivery period. At the time of delivery in the case of fixed-income securities
pursuant to the contract, adjustments are made to recognize differences in value
arising from the delivery of securities with a different interest rate than that
specified in the contract. In some cases, securities called for by a futures
contract may not have been issued at the time the contract was written. A Fund
will not enter into any futures contracts or options on futures contracts if the
aggregate of the market value of the outstanding futures contracts of the Fund
and futures contracts subject to the outstanding options written by the Fund
would exceed 50% of the total assets of the Fund.

Although some financial futures contracts by their terms call for the actual
delivery or acquisition of securities, in most cases, a party will close out the
contractual commitment before delivery without having to make or take delivery
of the security by purchasing (or selling, as the case may be) on a commodities
exchange an identical futures contract calling for delivery in the same month.
Such a transaction, if effected through a member of an exchange, cancels the
obligation to make or take delivery of the securities. All transactions in the
futures market are made, offset or fulfilled through a clearing house associated
with the exchange on which the contracts are traded. The Fund will incur
brokerage fees when they purchase or sell contracts and will be required to
maintain margin deposits. At the time a Fund enters into a futures contract, it
is required to deposit with its custodian, on behalf of the broker, a specified
amount of cash or eligible securities called "initial margin." The initial
margin required for a futures contract is set by the exchange on which the
contract is traded. Subsequent payments, called "variation margin," to and from
the broker are made on a daily basis as the market price of the futures contract
fluctuates. The costs incurred in connection with futures transactions could
reduce a Fund' return. Futures contracts entail risks. If the investment
adviser's judgment about the general direction of interest rates or markets is
wrong, the overall performance may be poorer than if no such contracts had been
entered into.

There may be an imperfect correlation between movements in prices of futures
contracts and portfolio securities being hedged. The degree of difference in
price movements between futures contracts and the securities being hedged
depends upon such things as variations in speculative market demand for futures
contracts and debt securities and differences between the securities being
hedged and the securities underlying the futures contracts, e.g., interest
rates, tax status, maturities and creditworthiness of issuers. While interest
rates on taxable securities generally move in the same direction as the interest
rates on municipal bonds, frequently there are differences in the rate of such
movements and temporary dislocations. Accordingly, the use of a financial
futures contract on a taxable security or a taxable securities index may involve
a greater risk of an imperfect correlation between the price movements of the
futures contract and of the municipal bond being hedged than when using a
financial futures contract on a municipal bond or a municipal bond index. In
addition, the market prices of futures contracts may be affected by certain
factors. If participants in the futures market elect to close out their
contracts through offsetting transactions rather than meet margin requirements,
distortions in the normal relationship could result. Price distortions also
could result if investors in futures contracts 


                                       5
<PAGE>

decide to make or take delivery of underlying securities rather than engage in
closing transactions because of the resultant reduction in the liquidity of the
futures market. In addition, because, from the point of view of speculators,
margin requirements in the futures market are less onerous than margin
requirements in the cash market, increased participation by speculators in the
futures market could cause temporary price distortions. Due to the possibility
of price distortions in the futures market and because of the imperfect
correlation between movements in the prices of securities and movements in the
prices of futures contracts, a correct forecast of market trends by the
investment adviser still may not result in a successful hedging transaction. If
any of these events should occur, a Fund could lose money on the financial
futures contracts and also on the value of its portfolio securities.

Options on Financial Futures Contracts. Each Fund may purchase and write call
and put options on financial futures contracts. An option on a futures contract
gives the purchaser the right, in return for the premium paid, to assume a
position in a futures contract at a specified exercise price at any time during
the period of the option. Upon exercise, the writer of the option delivers the
futures contract to the holder at the exercise price. A Fund would be required
to deposit with its custodian initial margin and maintenance margin with respect
to put and call options on futures contracts written by it. Options on futures
contracts involve risks similar to the risks relating to transactions in
financial futures contracts described above. Also, an option purchased by a Fund
may expire worthless, in which case the Fund would lose the premium paid
therefor.

Options on Securities. Each Fund may write (sell) covered call options on
securities so long as it owns securities which are acceptable for escrow
purposes and may write secured put options on securities, which means that, so
long as a Fund is obligated as a writer of a put option, it will invest an
amount not less than the exercise price of the put option in eligible
securities. A call option gives the purchaser the right to buy, and the writer
the obligation to sell, the underlying security at the exercise price during the
option period. A put option gives the purchaser the right to sell, and the
writer has the obligation to buy, the underlying security at the exercise price
during the option period. The premium received for writing an option will
reflect, among other things, the current market price of the underlying
security, the relationship of the exercise price to such market price, the price
volatility of the underlying security, the option period, supply and demand and
interest rates. A Fund may write or purchase spread options which are options
for which the exercise price may be a fixed-dollar spread or yield spread
between the security underlying the option and another security it does not own,
but which is used as a benchmark. The exercise price of an option may be below,
equal to, or above the current market value of the underlying security at the
time the option is written. The buyer of a put who also owns the related
security is protected by ownership of a put option against any decline in that
security's price below the exercise price less the amount paid for the option.
The ability to purchase put options allows a Fund to protect capital gains in an
appreciated security it owns, without being required to actually sell that
security. At times a Fund might like to establish a position in securities upon
which call options are available. By purchasing a call option, the Fund is able
to fix the cost of acquiring the security, this being the cost of the call plus
the exercise price of the option. This procedure also provides some protection
from an unexpected downturn in the market because the Fund is only at risk for
the amount of the premium paid for the call option which it can, if it chooses,
permit to expire.

During the option period, the covered call writer gives up the potential for
capital appreciation above the exercise price should the underlying security
rise in value, and the secured put writer retains the risk of loss should the
underlying security decline in value. For the covered call writer, substantial
appreciation in the value of the underlying security would result in the
security being "called away." For the secured put writer, substantial
depreciation in the value of the underlying security would result in the
security being "put to" the writer. If a covered call option expires
unexercised, the writer realizes a gain and the buyer a loss in the amount of
the premium. If the covered call option writer has to sell the underlying
security because of the exercise of the call option, the writer realizes a gain
or loss from the sale of the underlying security, with the proceeds being
increased by the amount of the premium.

If a secured put option expires unexercised, the writer realizes a gain and the
buyer a loss in the amount of the premium. If the secured put writer has to buy
the underlying security because of the exercise of the put option, the secured
put writer incurs an unrealized loss to the extent that the current market value
of the underlying security is less than the exercise price of the put option,
minus the premium received.

Over-the-Counter Options. As indicated in the Prospectus, each Fund may deal in
over-the-counter traded options ("OTC options"). OTC options differ from
exchange-traded options in several respects. They are transacted directly with
dealers and not with a clearing corporation and there is a risk of
nonperformance by the dealer as a result of the insolvency of such dealer or
otherwise, in which event, the Fund may experience material losses. However, in
writing 


                                       6
<PAGE>

options, the premium is paid in advance by the dealer. OTC options are available
for a greater variety of securities, and a wider range of expiration dates and
exercise prices, than are exchange-traded options. Since there is no exchange,
pricing normally is done by reference to information from market makers, which
information is carefully monitored by the Fund' investment adviser and verified
in appropriate cases.

A writer or purchaser of a put or call option can terminate it voluntarily only
by entering into a closing transaction. In the case of OTC options, there can be
no assurance that a continuous liquid secondary market will exist for any
particular option at any given time. Consequently, a Fund may be able to realize
the value of an OTC option it has purchased only by exercising it or entering
into a closing sale transaction with the dealer that issued it. Similarly, when
a Fund writes an OTC option, generally it can close out that option prior to its
expiration only by entering into a closing purchase transaction with the dealer
to which the Fund originally wrote it. If a covered call option writer cannot
effect a closing transaction, it cannot sell the underlying security until the
option expires or the option is exercised. Therefore, a covered call option
writer of an OTC option may not be able to sell an underlying security even
though it might otherwise be advantageous to do so. Likewise, a secured put
writer of an OTC option may be unable to sell the securities pledged to secure
the put for other investment purposes while it is obligated as a put writer.
Similarly, a purchaser of such put or call option also might find it difficult
to terminate its position on a timely basis in the absence of a secondary
market.

The Fund understands the position of the staff of the Securities and Exchange
Commission ("SEC") to be that purchased OTC options and the assets used as
"cover" for written OTC options are illiquid securities. The Fund and its
investment adviser disagree with this position and believe that the dealers with
which they intend to engage in OTC options transactions generally are agreeable
to and capable of entering into closing transactions. The Fund has adopted
procedures for engaging in OTC options for the purpose of reducing any potential
adverse effect of such transactions upon the liquidity of a Fund' portfolio. A
description of such procedures is set forth below.

The Fund only will engage in OTC options transactions with dealers that have
been specifically approved by the Board of Directors of the Fund. The Fund and
their investment adviser believe that such dealers present minimal credit risks
to the Fund and, therefore, should be able to enter into closing transactions if
necessary. The Fund currently will not engage in OTC options transactions if the
amount invested by the Fund in OTC options plus a "liquidity charge" related to
OTC options written by the Fund, plus the amount invested by the Fund in
illiquid securities, would exceed 10% of the Fund's net assets. The "liquidity
charge" referred to above is computed as described below.

The Fund anticipates entering into agreements with dealers to which the Fund
sell OTC options. Under these agreements a Fund would have the absolute right to
repurchase the OTC options from the dealer at any time at a price no greater
than a price established under the agreements (the "Repurchase Price"). The
"liquidity charge" referred to above for a specific OTC option transaction will
be the Repurchase Price related to the OTC option less the intrinsic value of
the OTC option. The intrinsic value of an OTC call option for such purposes will
be the amount by which the current market value of the underlying security
exceeds the exercise price. In the case of an OTC put option, intrinsic value
will be the amount by which the exercise price exceeds the current market value
of the underlying security. If there is no such agreement requiring a dealer to
allow a Fund to repurchase a specific OTC option written by the Fund, the
"liquidity charge" will be the current market value of the assets serving as
"cover" for such OTC option.

Options on Securities Indices. Each Fund also may purchase and write call and
put options on securities indices in an attempt to hedge against market
conditions affecting the value of securities that the Fund owns or intends to
purchase, and not for speculation. Through the writing or purchase of index
options, a Fund can achieve many of the same objectives as through the use of
options on individual securities. Options on securities indices are similar to
options on a security except that, rather than the right to take or make
delivery of a security at a specified price, an option on a securities index
gives the holder the right to receive, upon exercise of the option, an amount of
cash, if the closing level of the securities index upon which the option is
based is greater than, in the case of a call, or less than, in the case of a
put, the exercise price of the option. This amount of cash is equal to the
difference between the closing price of the index and the exercise price of the
option. The writer of the option is obligated, in return for the premium
received, to make delivery of this amount. Unlike security options, all
settlements are in cash and gain or loss depends upon price movements in the
market generally (or in a particular industry or segment of the market), rather
than upon price movements in individual securities. Price movements in
securities which a Fund owns or intends to purchase probably will not correlate
perfectly with movements in the level of an index and, therefore, the Fund bears
the risk that a loss on an index option would not be completely offset by
movements in the price of such securities.


                                       7
<PAGE>

When a Fund writes an option on a securities index, it will be required to
deposit with its custodian and mark-to-market eligible securities equal in value
to at least 100% of the exercise price in the case of a put or the contract
value in the case of a call. In addition, where a Fund writes a call option on a
securities index at a time when the contract value exceeds the exercise price,
the Fund will segregate and mark to market cash or cash equivalents equal in
value to such excess until the option expires or is closed out.

Options on futures contracts and index options involve risks similar to those
risks relating to transactions in financial futures contracts described above.
Also, an option purchased by a Fund may expire worthless, in which case the Fund
would lose the premium paid therefor.

Delayed Delivery Transactions. Each Fund may purchase or sell portfolio
securities on a when-issued or delayed delivery basis. When-issued or delayed
delivery transactions involve a commitment by the Fund to purchase or sell
securities with payment and delivery to take place in the future in order to
secure what is considered to be an advantageous price or yield to the Fund at
the time of entering into the transaction. When a Fund enters into a delayed
delivery purchase, it becomes obligated to purchase securities and it has all
the rights and risks attendant to ownership of a security, although delivery and
payment occur at a later date. The value of fixed- income securities to be
delivered in the future will fluctuate as interest rates vary. At the time the
Fund makes the commitment to purchase a security on a when-issued or delayed
delivery basis, it will record the transaction and reflect the liability for the
purchase and the value of the security in determining its net asset value.
Likewise, at the time the Fund makes the commitment to sell a security on a
delayed delivery basis, it will record the transaction and include the proceeds
to be received in determining its net asset value; accordingly, any fluctuations
in the value of the security sold pursuant to a delayed delivery commitment are
ignored in calculating net asset value so long as the commitment remains in
effect. The Fund, generally, have the ability to close out a purchase obligation
on or before the settlement date rather than take delivery of the security.

To the extent the Fund engage in when-issued or delayed delivery purchases, they
will do so for the purpose of acquiring portfolio securities consistent with the
Fund' investment objectives and policies and not for investment leverage or to
speculate in interest rate changes. The Fund only will make commitments to
purchase securities on a when-issued or delayed delivery basis with the
intention of actually acquiring the securities, but the Fund reserve the right
to sell these securities before the settlement date if deemed advisable.

Regulatory Restrictions. To the extent required to comply with Securities and
Exchange Commission Release No. IC-10666, when purchasing a futures contract,
writing a put option or entering into a delayed delivery purchase, each Fund
will maintain, in a segregated account, cash or high-grade marketable debt
securities equal to the value of such contracts.

To the extent required to comply with Commodities Futures Trading Commission
Regulation 4.5 and thereby avoid "commodity pool operator" status, no Fund will
enter into a futures contract or purchase an option thereon if immediately
thereafter the initial margin deposits for futures contracts held by the Fund
plus premiums paid by it for open options on futures would exceed 5% of the
Fund' total assets. A Fund will not engage in transactions in financial futures
contracts or options thereon for speculation, but only to attempt to hedge
against changes in market conditions affecting the values of securities which
the Fund holds or intends to purchase. When futures contracts or options thereon
are purchased to protect against a price increase on securities intended to be
purchased later, it is anticipated that at least 75% of such intended purchases
will be completed. When other futures contracts or options thereon are
purchased, the underlying value of such contracts at all times will not exceed
the sum of: (1) accrued profits on such contracts held by the broker; (2) cash
or high-quality money market instruments set aside in an identifiable manner and
(3) cash proceeds from investments due within 30 days.

1.    Outside directors' fees, including attendance fees for board and committee
      meetings, are allocated among all Lord Abbett-sponsored funds based on the
      net assets of each fund. A portion of the fees payable by the Fund to its
      outside directors is being deferred under a plan that deems the deferred
      amounts to be invested in shares of the Fund for later distribution to the
      directors.

2.    The amounts in Column 3 were accrued by the Lord Abbett-sponsored Funds
      for the twelve months ended October 31, 1998 with respect to the equity
      based plans established for independent directors in 1996. This plan
      supercedes a previously approved retirement plan for all future directors.
      Current directors had the option to convert their accrued benefits under
      the retirement plan. All of the outside directors except one made such an
      election. Each plan also provides for a pre-retirement death benefit and
      actuarially reduced joint-and-survivor spousal benefits.

3.    This column shows aggregate compensation, including directors fees and
      attendance fees for board and committee meetings, of a nature referred to
      in footnote one, accrued by the Lord Abbett-sponsored funds during the
      year ended

      December 31, 1998. The amounts of the aggregate compensation payable by
      the Fund as of September 30, 1998 deemed invested in Fund shares,
      including dividends reinvested and changes in net asset value applicable
      to such deemed investments, were: Mr. Bigelow, $31,357; Mr. Dixon,
      $41,649; Mr. Jansing, $116,723; Mr. MacDonald, $51,213; Mr. Millican,
      $117,535 and Mr. Neff, $118,321. If the amounts deemed invested in Fund
      shares were added to each director's actual holdings of Fund shares as of
      September 30, 1998, each would own, the following: Mr. Bigelow, shares;
      Mr. Dixon, shares; Mr. Jansing, shares; Mr. McDonald, shares; Mr.
      Millican, shares; and Mr. Neff, shares.

4.    Mr. Jansing chose to continue to receive benefits under the retirement
      plan which provides that outside directors (Trustees) may receive annual
      retirement benefits for life equal to their final annual retainer
      following retirement at or after age 72 with at least ten years of
      service. Thus, if Mr. Jansing were to retire and the annual retainer
      payable by the funds were the same as it is today, he would receive annual
      retirement benefits of $50,000.

Except where indicated, the following executive officers of the Fund have been
associated with Lord Abbett for over five years. Of the following, Messrs.

                                       4.
                             Portfolio Transactions

Purchases and sales of portfolio securities usually will be principal
transactions and normally such securities will be purchased directly from the
issuer or from an underwriter or purchased from or sold to a market maker for
the securities. Therefore, the Fund usually will pay no brokerage commissions on
such transaction. Purchases from underwriters of portfolio securities will
include a commission or concession paid by the issuer to the underwriter and
purchases from or sales to dealers serving as market makers will include a
dealer's markup or markdown. Principal transactions, including riskless
principal transactions, are not afforded the protection of the safe harbor in
Section 28 (e) of the Securities Exchange Act of 1934.

Our policy is to obtain best execution on all our portfolio transactions, which
means that we seek to have purchases and sales of portfolio securities executed
at the most favorable prices, considering all costs of the transaction including
dealer markups and markdowns and any brokerage commissions. This policy governs
the selection of brokers or dealers and the market in which the transaction is
executed. To the extent permitted by law, we may, if considered advantageous,
make a purchase from or sale to another Lord Abbett-sponsored fund without the
intervention of any broker-dealer.

Broker-dealers are selected on the basis of their professional capability and
the value and quality of their brokerage and research services. Normally, the
selection is made by traders who are officers of the Fund and also are employees
of Lord Abbett. These traders do the trading as well for other accounts --
investment companies (of which they are also officers) and other investment
clients -- managed by Lord Abbett. They are responsible for negotiation of
prices and any commissions.

We may pay a brokerage commission on the purchase or sale of a security that
could be purchased from or sold to a market maker if our net cost of the
purchase or the net proceeds to us of the sale are at least as favorable as we
could obtain on a direct purchase or sale. Brokers who receive such commissions
may also provide research services at least some of which are useful to Lord
Abbett in their overall responsibilities with respect to us and the other
accounts they manage. Research includes trading equipment and computer software
packages, acquired from third-party suppliers, that enable Lord Abbett to access
various information bases and may include the furnishing of analyses and reports


                                       13
<PAGE>

concerning issuers, industries, securities, economic factors and trends,
portfolio strategy and the performance of accounts. Such services may be used by
Lord Abbett in servicing all their accounts, and not all of such services will
necessarily be used by Lord Abbett in connection with their management of the
Fund; conversely, such services furnished in connection with brokerage on other
accounts managed by Lord Abbett may be used in connection with their management
of the Fund, and not all of such services will necessarily be used by Lord
Abbett in connection with their advisory services to such other accounts. We
have been advised by Lord Abbett that research services received from brokers
cannot be allocated to any particular account, are not a substitute for Lord
Abbett's services but are supplemental to their own research effort and, when
utilized, are subject to internal analysis before being incorporated by Lord
Abbett into their investment process. As a practical matter, it would not be
possible for Lord Abbett to generate all of the information presently provided
by brokers. While receipt of research services from brokerage firms has not
reduced Lord Abbett's normal research activities, the expenses of Lord Abbett
could be materially increased if it attempted to generate such additional
information through its own staff and purchased such equipment and software
packages directly from the suppliers.

No commitments are made regarding the allocation of brokerage business to or
among brokers, and trades are executed only when they are dictated by investment
decisions of the Fund to purchase or sell portfolio securities.

If two or more broker-dealers are considered capable of offering the equivalent
likelihood of best execution, the broker-dealer who has sold our shares and/or
shares of other Lord Abbett-sponsored funds may be preferred.

If other clients of Lord Abbett buy or sell the same security at the same time
as we do, transactions will, to the extent practicable, be allocated among all
participating accounts in proportion to the amount of each order and will be
executed daily until filled so that each account shares the average price and
commission cost of each day. Other clients who direct that their brokerage
business be placed with specific brokers or who invest through wrap accounts
introduced to Lord Abbett by certain brokers may not participate with us in the
buying and selling of the same securities as described above. If these clients
wish to buy or sell the same security as we do, they may have their transactions
executed at times different from our transactions and thus may not receive the
same price or incur the same commission cost as we do.

We will not seek "reciprocal" dealer business (for the purpose of applying
commissions in whole or in part for our benefit or otherwise) from dealers as
consideration for the direction to them of portfolio business.

During the fiscal years ending September 30, 1996, 1997 and 1998, we paid no
commissions to independent dealers.


                                       5.
                             Purchases, Redemptions
                            and Shareholder Services

The Fund values its portfolio securities at market value as of the close of the
NYSE. Market value will be determined as follows: securities listed or admitted
to trading privileges on the New York or American Stock Exchange or on the
NASDAQ National Market System are valued at the last sales price, or, if there
is no sale on that day, at the mean between the last bid and asked prices, or,
in the case of bonds, in the over-the-counter market if, in the judgment of the
Fund's officers, that market more accurately reflects the market value of the
bonds. Over-the-counter securities not traded on the NASDAQ National Market
System are valued at the mean between the last bid and asked prices. Securities
for which market quotations are not available are valued at fair market value
under procedures approved by the Board of Directors.

Information concerning how we value our shares for the purchase and redemption
of our shares is described in the Prospectus under "Purchases" and
"Redemptions", respectively.

As disclosed in the Prospectus, we calculate our net asset value and are
otherwise open for business on each day that the NYSE is open for trading. The
NYSE is closed on Saturdays and Sundays and 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.

The net asset value per share for the Class B and Class C shares is determined
in the same manner as for the Class A


                                       14
<PAGE>

shares (net assets divided by shares outstanding). Our Class B and Class C
shares are sold at net asset value.

The maximum offering prices of our Class A shares on September 30, 1998 were
computed as follows:

Conversion of Class B Shares. The conversion of Class B shares of the National
Fund on the eighth anniversary of their purchase is subject to the continuing
availability of a private letter ruling from the Internal Revenue Service or an
opinion of counsel to the effect that the conversion of Class B shares does not
constitute a taxable event for the holder under Federal income tax law. If such
a revenue ruling or opinion is no longer available, the automatic conversion
feature may be suspended, in which event no further conversions of Class B
shares would occur while such suspension remained in effect. Although Class B
shares could then be exchanged for Class A shares on the basis of relative net
asset value of the two classes, without the imposition of a sales charge or fee,
such exchange could constitute a taxable event for the holder.

ALTERNATIVE SALES ARRANGEMENTS

Classes of Shares. This Prospectus offers three classes of shares designated as
Class A, B, C and P (which may differ for each Fund). The different classes of
shares represent investments in the same portfolio of securities but are subject
to different expenses and will likely have different share prices. Investors
should read this section carefully to determine which class represents the best
investment option for their particular situation.

Class A Shares. If you buy Class A shares, you pay an initial sales charge on
investments of less than $1 million (or on investments for employer-sponsored
retirement plans under the Internal Revenue Code (hereinafter referred to as
"Retirement Plans") with less than 100 eligible employees or on investments that
do not qualify to be under a "special retirement wrap program" as a program
sponsored by an authorized institution showing one or more characteristics
distinguishing it, in the opinion of Lord Abbett Distributor from a mutual fund
wrap fee program). If you purchase Class A shares as part of an investment of at
least $1 million (or for Retirement Plans with at least 100 eligible employees
or under a special retirement wrap program) in shares of one or more Lord
Abbett-sponsored funds, you will not pay an initial sales charge, but if you
redeem any of those shares within 24 months after the month in which you buy
them, you may pay to the Fund a contingent deferred sales charge ("CDSC") of 1%
except for redemptions under a special retirement wrap program. Class A shares
are subject to service and distribution fees that are currently estimated to
total annually approximately 0.23 of 1% of the annual net asset value of the
Class A shares. The initial sales charge rates, the CDSC and the Rule 12b-1 plan
applicable to the Class A shares are described in "Buying Class A Shares" below.

Class B Shares. If you buy Class B shares, you pay no sales charge at the time
of purchase, but if you redeem your shares before the sixth anniversary of
buying them, you will normally pay a CDSC to Lord Abbett Distributor LLC 


                                       16
<PAGE>

("Lord Abbett Distributor"). That CDSC varies depending on how long you own
shares. Class B shares are subject to service and distribution fees at an annual
rate of 1% of the annual net asset value of the Class B shares. The CDSC and the
Rule 12b-1 plan applicable to the Class B shares are described in "Buying Class
B Shares" below.

Class C Shares. If you buy Class C shares, you pay no sales charge at the time
of purchase, but if you redeem your shares before the first anniversary of
buying them, you will normally pay the Fund a CDSC of 1%. Class C shares are
subject to service and distribution fees at an annual rate of 1% of the annual
net asset value of the Class C shares. The CDSC and the Rule 12b-1 plan
applicable to the C shares are described in "Buying Class C Shares" below.

Which Class of Shares Should You Choose? Once you decide that the Fund is an
appropriate investment for you, the decision as to which class of shares is
better suited to your needs depends on a number of factors which you should
discuss with your financial adviser. The Fund's class-specific expenses and the
effect of the different types of sales charges on your investment will affect
your investment results over time. The most important factors are how much you
plan to invest and how long you plan to hold your investment. If your goals and
objectives change over time and you plan to purchase additional shares, you
should re-evaluate those factors to see if you should consider another class of
shares.

In the following discussion, to help provide you and your financial adviser with
a framework in which to choose a class, we have made some assumptions using a
hypothetical investment in the Fund. We used the sales charge rates that apply
to Class A, Class B and Class C, and considered the effect of the higher
distribution fees on Class B and Class C expenses (which will affect your
investment return). Of course, the actual performance of your investment cannot
be predicted and will vary, based on the Fund's actual investment returns, the
operating expenses borne by each class of shares, and the class of shares you
purchase. The factors briefly discussed below are not intended to be investment
advice, guidelines or recommendations, because each investor's financial
considerations are different. The discussion below of the factors to consider in
purchasing a particular class of shares assumes that you will purchase only one
class of shares and not a combination of shares of different classes.

How Long Do You Expect to Hold Your Investment? While future financial needs
cannot be predicted with certainty, knowing how long you expect to hold your
investment will assist you in selecting the appropriate class of shares. For
example, over time, the reduced sales charges available for larger purchases of
Class A shares may offset the effect of paying an initial sales charge on your
investment, compared to the effect over time of higher class-specific expenses
on Class B or Class C shares for which no initial sales charge is paid. Because
of the effect of class-based expenses, your choice should also depend on how
much you plan to invest.

Investing for the Short Term. If you have a short-term investment horizon (that
is, you plan to hold your shares for not more than six years), you should
probably consider purchasing Class A or Class C shares rather than Class B
shares. This is because of the effect of the Class B CDSC if you redeem before
the sixth anniversary of your purchase, as well as the effect of the Class B
distribution fee on the investment return for that class in the short term.
Class C shares might be the appropriate choice (especially for investments of
less than $100,000), because there is no initial sales charge on Class C shares,
and the CDSC does not apply to amounts you redeem after holding them one year.

However, if you plan to invest more than $100,000 for the short term, then the
more you invest and the more your investment horizon increases toward six years,
the more attractive the Class A share option may become. This is because the
annual distribution fee on Class C shares will have a greater impact on your
account over the longer term than the reduced front-end sales charge available
for larger purchases of Class A shares. For example, Class A might be more
appropriate than Class C for investments of more than $100,000 expected to be
held for 5 or 6 years (or more). For investments over $250,000 expected to be
held 4 to 6 years (or more), Class A shares may become more appropriate than
Class C. If you are investing $500,000 or more, Class A may become more
desirable as your investment horizon approaches 3 years or more.

For most investors who invest $1 million or more or for Retirement Plans with at
least 100 eligible employees or for investments pursuant to a special retirement
wrap program, in most cases Class A shares will be the most advantageous choice,
no matter how long you intend to hold your shares. For that reason, it may not
be suitable for you to place a purchase order for Class B shares of $500,000 or
more or a purchase order for Class C shares of 


                                       17
<PAGE>

$1,000,000 or more. In addition, it may not be suitable for you to place an
order for Class B or C shares for a Retirement Plan with at least 100 eligible
employees or for a special retirement wrap program. You should discuss this with
your financial advisor.

Investing for the Longer Term. If you are investing for the longer term (for
example, to provide for future college expenses for your child) and do not
expect to need access to your money for seven years or more, Class B shares may
be an appropriate investment option, if you plan to invest less than $100,000.
If you plan to invest more than $100,000 over the long term, Class A shares will
likely be more advantageous than Class B shares or Class C shares, as discussed
above, because of the effect of the expected lower expenses for Class A shares
and the reduced initial sales charges available for larger investments in Class
A shares under the Fund's Rights of Accumulation. Of course, these examples are
based on approximations of the effect of current sales charges and expenses on a
hypothetical investment over time, and should not be relied on as rigid
guidelines.

Are There Differences in Account Features That Matter to You? Some account
features are available in whole or in part to Class A, Class B and Class C
shareholders. Other features (such as Systematic Withdrawal Plans) might not be
advisable in non-Retirement Plan accounts for Class B shareholders (because of
the effect of the CDSC on the entire amount of a withdrawal if it exceeds 12%
annually) and in any account for Class C shareholders during the first year of
share ownership (due to the CDSC on withdrawals during that year). See
"Systematic Withdrawal Plan" under "Shareholder Services" in the Prospectus for
more information about the 12% annual waiver of the CDSC. You should carefully
review how you plan to use your investment account before deciding which class
of shares you buy. For example, the dividends payable to Class B and Class C
shareholders will be reduced by the expenses borne solely by each of these
classes, such as the higher distribution fee to which Class B and Class C shares
are subject, as described below.

How Does It Affect Payments to My Broker? A salesperson, such as a broker, or
any other person who is entitled to receive compensation for selling Fund shares
may receive different compensation for selling one class than for selling
another class. As discussed in more detail below, such compensation is primarily
paid at the time of sale in the case of Class A and B shares and is paid over
time, so long as shares remain outstanding, in the case of Class C shares. It is
important that investors understand that the primary purpose of the CDSC for the
Class B shares and the distribution fee for Class B and Class C shares is the
same as the purpose of the front-end sales charge on sales of Class A shares: to
compensate brokers and other persons selling such shares. The CDSC, if payable,
supplements the Class B distribution fee and reduces the Class C distribution
fee expenses for the Fund and Class C shareholders.

Class A, B and C Rule 12b-1 Plans. As described in the Prospectus, the Fund has
adopted a Distribution Plan and Agreement on behalf of each Fund pursuant to
Rule 12b-1 of the Act for each class of such Fund: the "A Plan" (all Fund), the
"B Plan" (National Fund only) and the "C Plan" (National, New York and
California Fund only), respectively. In adopting each Plan and in approving its
continuance, the Board of Directors has concluded that there is a reasonable
likelihood that each Plan will benefit its respective Class and such Class'
shareholders. The expected benefits include greater sales and lower redemptions
of shares, which should allow each Class to maintain a consistent cash flow, and
a higher quality of service to shareholders by authorized institutions than
would otherwise be the case. Lord Abbett used all amounts received under the A,
B and C Plans for payments to dealers for (i) providing continuous services to
the shareholders, such as answering shareholder inquiries, maintaining records,
and assisting shareholders in making redemptions, transfers, additional
purchases and exchanges and (ii) their assistance in distributing shares of each
Fund.

The fees payable under the A, B and C Plans are described in the Prospectus. For
the fiscal year ended September 30, 1998 fees paid to dealers under the A Plans
were as follows: National Fund $1,597,953; New York Fund $726,923 California
Fund $706,386; Texas Fund $206,855; New Jersey Fund $464,497; Connecticut Fund
$249,641; Missouri Fund $436,037and Hawaii Fund $246,740.

For the fiscal year ended September 30, 1998 fees paid to dealers under the B
Plan for the National Fund were $51,071. For the fiscal year ended September 30,
1998 fees paid under the C Plan for the National, New York and California Fund
were $416,101, $62,541and $141,182.

Each Plan requires the Board of Directors to review, on a quarterly basis,
written reports of all amounts expended pursuant to the Plan and the purposes
for which such expenditures were made. Each Plan shall continue in effect only
if its continuance is specifically approved at least annually by vote of the
Board of Directors and of the directors who 


                                       18
<PAGE>

are not interested persons of the Fund and who have no direct or indirect
financial interest in the operation of the Plan or in any agreements related to
the Plan ("outside directors"), cast in person at a meeting called for the
purpose of voting on the Plan and agreements. No Plan may be amended to increase
materially the amount spent for distribution expenses without approval by a
majority of the outstanding voting securities of the relevant class of the Fund
in question and the approval of a majority of the directors, including a
majority of the outside directors. Each Plan may be terminated at any time by
vote of a majority of the outside directors or by vote of the holders of a
majority of the outstanding voting securities of the relevant class of the Fund
in question.

Contingent Deferred Sales Charges. A Contingent Deferred Sales Charge ("CDSC"),
applies upon early redemption of shares, regardless of class, and (i) will be
assessed on the lesser of the net asset value of the shares at the time of
redemption or the original purchase price and (ii) is not imposed on the amount
of your account value represented by the increase in net asset value over the
initial purchase price (including increases due to the reinvestment of dividends
and capital gains distributions).

Class A Shares. As stated in the Prospectus, a CDSC is imposed with respect to
those Class A shares (or Class A shares of another Lord Abbett-sponsored fund or
fund acquired through exchange of such shares) on which a Fund has paid the
one-time 1% distribution fee if such shares are redeemed out of the Lord
Abbett-sponsored family of funds within a period of 24 months from the end of
the month in which the original sale occurred.

Class B Shares (National Fund only). As stated in the Prospectus, if Class B
shares of the National Fund (or Class B shares of another Lord Abbett-sponsored
fund or fund acquired through exchange of such shares) are redeemed out of the
Lord Abbett-sponsored family of funds for cash before the sixth anniversary of
their purchase, a CDSC will be deducted from the redemption proceeds. The Class
B CDSC is paid to Lord Abbett Distributor to reimburse its expenses, in whole or
in part, of providing distribution-related service to the Fund in connection
with the sale of Class B shares.

To determine whether the CDSC applies to a redemption, the Fund redeem shares in
the following order: (1) shares acquired by reinvestment of dividends and
capital gains distributions, (2) shares held on or after the sixth anniversary
of their purchase, and (3) shares held the longest before such sixth
anniversary.

The amount of the contingent deferred sales charge will depend on the number of
years since you invested and the dollar amount being redeemed, according to the
following schedule:

Anniversary of                            Contingent Deferred Sales Charge
Purchase                       on Redemptions (As % of Amount Subject to Charge)
Before the 1st                                       5.0%
On the 1st, before the 2nd                           4.0%
On the 2nd, before the 3rd                           3.0%
On the 3rd, before the 4th                           3.0%
On the 4th, before the 5th                           2.0%
On the 5th, before the 6th                           1.0%
On or after the 6th anniversary                      None

In the table, an "anniversary" is the 365th day subsequent to the acceptance of
a purchase order or a prior anniversary. All purchases are considered to have
been made on the business day on which the purchase order was accepted.

Class C Shares (National, New York and California fund only). As stated in the
Prospectus, if Class C shares are redeemed for cash before the first anniversary
of their purchase, the redeeming shareholder will be required to pay to the
applicable Fund on behalf of Class C shares a CDSC of 1% of the lower of cost or
the then net asset value of Class C shares redeemed. If such shares are
exchanged into the same class of another Lord Abbett-sponsored fund and
subsequently redeemed before the first anniversary of their original purchase,
the charge will be collected by the other fund on behalf of the Fund' Class C
shares.

General. Each percentage (1% in the case of Class A and C shares and 5% through
1% in the case of Class B shares) used to calculate CDSCs described above for
the Class A, Class B and Class C shares is sometimes hereinafter referred to as
the "Applicable Percentage".


                                       19
<PAGE>

With respect to Class A and Class B shares, no CDSC is payable on redemptions by
participants or beneficiaries from employer-sponsored retirement plans under the
Internal Revenue Code for benefit payments due to plan loans, hardship
withdrawals, death, retirement or separation from service and for returns of
excess contributions to retirement plan sponsors. In the case of Class A and
Class C shares, the CDSC is received by the applicable Fund and is intended to
reimburse all or a portion of the amount paid by the Fund if the shares are
redeemed before the Fund has had an opportunity to realize the anticipated
benefits of having a long-term shareholder account in the Fund. In the case of
Class B shares, the CDSC is received by Lord Abbett Distributor and is intended
to reimburse its expenses of providing distribution-related service to the
National Fund (including recoupment of the commission payments made) in
connection with the sale of Class B shares before Lord Abbett Distributor has
had an opportunity to realize its anticipated reimbursement by having such a
long-term shareholder account subject to the B Plan distribution fee.

Rule 12b-1 Plan is not yet in effect, and (c) any authorized institution's
affiliated money market fund satisfying Lord Abbett Distributor as to certain
omnibus account and other criteria, hereinafter referred to as an "authorized
money market fund" or "AMMF" (collectively, the "Non-12b-1 Funds")) have
instituted a CDSC for each class on the same terms and conditions. No CDSC will
be charged on an exchange of shares of the same class between Lord Abbett funds
or between such funds and AMMF. Upon redemption of shares out of the Lord Abbett
family of funds or out of AMMF, the CDSC will be charged on behalf of and paid:
(i) to the fund in which the original purchase (subject to a CDSC) occurred, in
the case of the Class A and Class C shares and (ii) to Lord Abbett Distributor
if the original purchase was subject to a CDSC, in the case of the Class B
shares. Thus, if shares of a Lord Abbett fund are exchanged for shares of the
same class of another such fund and the shares of the same class tendered
("Exchanged Shares") are subject to a CDSC, the CDSC will carry over to the
shares of the same class being acquired, including GSMMF and AMMF ("Acquired
Shares"). Any CDSC that is carried over to Acquired Shares is calculated as if
the holder of the Acquired Shares had held those shares from the date on which
he or she became the holder of the Exchanged Shares. Although the Non-12b-1
Funds will not pay a distribution fee on their own shares, and will, therefore,
not impose their own CDSC, the Non-12b-1 Funds will collect the CDSC (a) on
behalf of other Lord Abbett funds, in the case of the Class A and Class C shares
and (b) on behalf of Lord Abbett Distributor, in the case of the Class B shares.
Acquired Shares held in GSMMF and AMMF which are subject to a CDSC will be
credited with the time such shares are held in GSMMF but will not be credited
with the time such shares are held in AMMF. Therefore, if your Acquired Shares
held in AMMF qualified for no CDSC or a lower Applicable Percentage at the time
of exchange into AMMF, that Applicable Percentage will apply to redemptions for
cash from AMMF, regardless of the time you have held Acquired Shares in AMMF.

In no event will the amount of the CDSC exceed the Applicable Percentage of the
lesser of: (i) the net asset value of the shares redeemed or (ii) the original
cost of such shares (or of the Exchanged Shares for which such shares were
acquired). No CDSC will be imposed when the investor redeems (i) amounts derived
from increases in the value of the account above the total cost of shares being
redeemed due to increases in net asset value, (ii) shares with respect to which
no Lord Abbett fund or fund paid a 12b-1 fee and, in the case of Class B shares,
Lord Abbett Distributor paid no sales charge or service fee (including shares
acquired through reinvestment of dividend income and capital gains
distributions) or (iii) shares which, together with Exchanged Shares, have been
held continuously for 24 months from the end of the month in which the original
sale occurred (in the case of Class A shares); for six years or more (in the
case of Class B shares) or for one year or more (in the case of Class C shares).
In determining whether a CDSC is payable, (a) shares not subject to the CDSC
will be redeemed before shares subject to the CDSC and (b) of the shares subject
to a CDSC, those held the longest will be the first to be redeemed.

Exchanges. The Prospectus briefly describes the Telephone Exchange Privilege.
You may exchange some or all of your shares for those of the same class of: (i)
Lord Abbett-sponsored funds currently offered to the public with a sales charge
(front-end, back-end or level), (ii) GSMMF or (iii) AMMF, to the extent offers
and sales may be made in your state. You should read the prospectus of the other
fund before exchanging. In establishing a new account by exchange, shares of the
Fund being exchanged must have a value equal to at least the minimum initial
investment required for the fund into which the exchange is made.

Shareholders in other Lord Abbett-sponsored funds and AMMF have the same right
to exchange their shares for the Fund's shares. Exchanges are based on relative
net asset values on the day instructions are received by the Fund in 


                                       20
<PAGE>

Kansas City if the instructions are received prior to the close of the NYSE in
proper form. No sales charges are imposed except in the case of exchanges out of
GSMMF or AMMF (unless a sales charge (front-end, back-end or level) was paid on
the initial investment). Exercise of the exchange privilege will be treated as a
sale for federal income tax purposes, and, depending on the circumstances, a
gain or loss may be recognized. In the case of an exchange of shares that have
been held for 90 days or less where no sales charge is payable on the exchange,
the original sales charge incurred with respect to the exchanged shares will be
taken into account in determining gain or loss on the exchange only to the
extent such charge exceeds the sales charge that would have been payable on the
acquired shares had they been acquired for cash rather than by exchange. The
portion of the original sales charge not so taken into account will increase the
basis of the acquired shares.

Shareholders have the exchange privilege unless they refuse it in writing. You
should not view the exchange privilege as a means for taking advantage of
short-term swings in the market, and we reserve the right to terminate or limit
the privilege of any shareholder who makes frequent exchanges. We can revoke or
modify the privilege for all shareholders upon 60 days' prior notice. "Eligible
Funds" are AMMF and other Lord Abbett-sponsored funds which are eligible for the
exchange privilege, except Lord Abbett Fund Fund ("LASF") which offers its
shares only in connection with certain variable annuity contracts, Lord Abbett
Equity Fund ("LAEF") which is not issuing shares, and fund of Lord Abbett
Research Fund not offered to the general public ("LARF").

Statement of Intention. Under the terms of the Statement of Intention to invest
$100,000 or more over a 13-month period as described in the Prospectus, shares
of Lord Abbett-sponsored funds (other than shares of LAEF, LASF, LARF and GSMMF,
unless holdings in GSMMF are attributable to shares exchanged from a Lord
Abbett-sponsored fund offered with a front-end, back-end or level sales charge)
currently owned by you are credited as purchases (at their current offering
prices on the date the Statement is signed) toward achieving the stated
investment and reduced initial charges for Class A shares. Class A shares valued
at 5% of the amount of intended purchases are escrowed and may be redeemed to
cover the additional sales charge payable if the Statement is not completed. The
Statement of Intention is neither a binding obligation on you to buy, nor on the
Fund to sell, the full amount indicated.

Rights of Accumulation. As stated in the Prospectus, purchasers (as defined in
the Prospectus) may accumulate their investment in Lord Abbett-sponsored funds
(other than LAEF, LARF, LASF, and GSMMF, unless holdings in GSMMF are
attributable to shares exchanged from a Lord Abbett-sponsored fund offered with
a front-end, back-end or level sales charge) so that a current investment, plus
the purchaser's holdings valued at the current maximum offering price, reach a
level eligible for a discounted sales charge for Class A shares.

Net Asset Value Purchases of Class A Shares. As stated in the Prospectus, our
Class A shares may be purchased at net asset value by our directors, employees
of Lord Abbett, employees of our shareholder servicing agent and employees of
any securities dealer having a sales agreement with Lord Abbett who consents to
such purchases or by the trustee or custodian under any pension or
profit-sharing plan or Payroll Deduction IRA established for the benefit of such
persons or for the benefit of employees of any national securities trade
organization to which Lord Abbett belongs or any company with an account(s) in
excess of $10 million managed by Lord Abbett on a private-advisory-account
basis. For purposes of this paragraph, the terms "directors" and "employees"
include a director's or employee's spouse (including the surviving spouse of a
deceased director or employee). The terms " directors" and "employees of Lord
Abbett" also include other family members and retired directors and employees.

Our Class A shares also may be purchased at net asset value (a) at $1 million or
more, (b) with dividends and distributions from Class A shares and other Lord
Abbett-sponsored funds, except for LARF, LAEF and LASF, (c) under the loan
feature of the Lord Abbett-sponsored prototype 403(b) plan for share purchases
representing the repayment of principal and interest, (d) by certain authorized
brokers, dealers, registered investment advisers or other financial institutions
who have entered into an agreement with Lord Abbett Distributor in accordance
with certain standards approved by Lord Abbett Distributor, providing
specifically for the use of our shares in particular investment products made
available for a fee to clients of such brokers, dealers, registered investment
advisers and other financial institutions, and (e) by employees, partners and
owners of unaffiliated consultants and advisors to Lord Abbett, Lord Abbett
Distributor or Lord Abbett-sponsored funds who consent to such purchase if such
persons provide service to Lord Abbett, Lord Abbett Distributor or such funds on
a continuing basis and are familiar with such funds. Shares are offered at net
asset value to these investors for the purpose of promoting goodwill with
employees and others with whom Lord Abbett Distributor and/or the Fund has
business relationships.


                                       21
<PAGE>

Our shares may be issued at net asset value in exchange for the assets, subject
to possible tax adjustment, of a personal holding company or an investment
company. There are economies of selling efforts and sales-related expenses with
respect to offers to these investors and those referred to above.

Redemptions. A redemption order is in proper form when it contains all of the
information and documentation required by the order form or supplementally by
Lord Abbett Distributor or the Fund to carry out the order. The signature(s) and
any legal capacity of the signer(s) must be guaranteed by an eligible guarantor.
See the Prospectus for expedited redemption procedures.

The right to redeem and receive payment, as described in the Prospectus, may be
suspended if the NYSE is closed (except for weekends or customary holidays),
trading on the NYSE is restricted or the Securities and Exchange Commission
deems an emergency to exist.

Our Board of Directors may authorize redemption of all of the shares in any
account in which there are fewer than 25 shares. Before authorizing such
redemption, the Board must determine that it is in our economic best interest or
necessary to reduce disproportionately burdensome expenses in servicing
shareholder accounts. At least 30 days' prior written notice will be given
before any such redemption, during which time shareholders may avoid redemption
by bringing their accounts up to the minimum set by the Board.

Div-Move. Under the Div-Move service described in the Prospectus, you can invest
the dividends paid on your account into an existing account in any other
Eligible Fund. The account must be either your account, a joint account for you
and your spouse, a single account for your spouse, or a custodial account for
your minor child under the age of 21. You should read the prospectus of the
other fund before investing.

Invest-A-Matic. The Invest-A-Matic method of investing in the Fund and/or any
other Eligible Fund is described in the Prospectus. To avail yourself of this
method you must complete the application form, selecting the time and amount of
your bank checking account withdrawals and the funds for investment, include a
voided, unsigned check and complete the bank authorization.

Systematic Withdrawal Plans. The Systematic Withdrawal Plan (the "SWP") also is
described in the Prospectus. You may establish a SWP if you own or purchase
uncertificated shares having a current offering price value of at least $10,000.
Lord Abbett prototype retirement plans have no such minimum. With respect to a
SWP for Class B shares, the CDSC will be waived on redemptions of up to 12% per
year of either the current net asset value of your account or your original
purchase price, whichever is higher. With respect to Class C shares, the CDSC
will be waived on and after the first anniversary of their purchase. The SWP
involves the planned redemption of shares on a periodic basis by receiving
either fixed or variable amounts at periodic intervals. Since the value of
shares redeemed may be more or less than their cost, gain or loss may be
recognized for income tax purposes on each periodic payment. Normally, you may
not make regular investments at the same time you are receiving systematic
withdrawal payments because it is not in your interest to pay a sales charge on
new investments when in effect a portion of that new investment is soon
withdrawn. The minimum investment accepted while a withdrawal plan is in effect
is $1,000. The SWP may be terminated by you or by us at any time by written
notice.

Retirement Plans. The Prospectus indicates the types of retirement plans for
which Lord Abbett provides forms and explanations. Lord Abbett makes available
the retirement plan forms and custodial agreements for IRAs (Individual
Retirement Accounts including Simplified Employee Pensions), 403(b) plans and
qualified pension and profit-sharing plans, including 401(k) plans. The forms
name Investors Fiduciary Trust Company as custodian and contain specific
information about the plans. Explanations of the eligibility requirements,
annual custodial fees and allowable tax advantages and penalties are set forth
in the relevant plan documents. Adoption of any of these plans should be on the
advice of your legal counsel or qualified tax adviser.

                                      Taxes

Each Fund will be treated as a separate entity for federal income tax purposes.
As a result, the status of each Fund as a regulated investment company is
determined separately by the Internal Revenue Service. Each Fund qualified as a
regulated investment company last fiscal year and intends to do so for this
fiscal year, if any fund does not qualify it will be taxed as a normal
corporation.

Interest on indebtedness incurred by a shareholder to purchase or carry shares
of the Fund may not be deductible, in whole or in part, for federal, or for
state or personal income tax purposes. Pursuant to published guidelines, the
Internal Revenue Service may deem indebtedness to have been incurred for the
purpose of acquiring or carrying shares of the Fund even though the borrowed
funds may not be directly traceable to the purchase of shares.

Our shares may not be an appropriate investment for "substantial users" of
facilities financed by industrial development bonds or persons related to such
"substantial users." Such persons should consult their tax advisers before
investing in shares of the Fund.

Certain financial institutions, like other taxpayers, may be denied a federal
income tax deduction for the amount of interest expense allocable to an
investment in the Fund and the deduction for loss reserves available to property
and casualty insurance companies may be reduced by a specified percentage as a
result of their investment in the Fund.

The value of any shares redeemed by the Fund or repurchased or otherwise sold
may be more or less than your tax basis at the time the redemption, repurchase
or sale is made. Any gain or loss generally will be taxable for federal income
tax purposes. Any loss realized on the sale, redemption or repurchase of Fund
shares held for six months or less will be treated for tax purposes as a
long-term capital loss to the extent of any distribution designated by the Fund
as a "capital gains distribution" received with respect to such shares.
Moreover, shareholders will not be allowed to recognize for tax purposes any
capital loss realized on the redemption or repurchase of Fund shares which they
have held for six months or less to the extent of any tax-exempt distributions
received on the shares. Losses on the sale of stock or securities are not
deductible if, within a period beginning 30 days before the date of the sale and
ending 30 days after the date of the sale, the taxpayer acquires stock or
securities that are substantially identical.

Each Fund will be subject to a 4% nondeductible excise tax on certain amounts
not distributed (and not treated as having been distributed) on a timely basis
in accordance with a calendar year distribution requirement. The Fund intends to
distribute to shareholders each year an amount adequate to avoid the imposition
of such excise taxes.

Limitations imposed by the Internal Revenue Code of 1986, as amended, on
regulated investment companies may restrict the Fund's ability to engage in the
options and financial futures transactions discussed above or in other
investment techniques and practices. Moreover, in order to continue to qualify
as a regulated investment company for federal income tax purposes, each Fund may
be required in some circumstances to defer closing out options or futures
contracts that might otherwise be desirable to close out. State law may restrict
a Fund' ability to engage in the options and financial futures transactions
discussed above. A current interpretation of New Jersey law issued by the New
Jersey Department of the Treasury would preclude the New Jersey Fund from
engaging in some or all of the options and financial futures transactions
discussed above. Each Fund may engage in such transactions to the extent they
currently are or become permissible under applicable state law.

Except as discussed in the Prospectus, the receipt of dividends from the Fund
may be subject to tax under laws of state or local tax authorities. You should
consult your tax adviser on state and local tax matters.

                                       7.
                       Risk Factors Regarding Investments
      in California, Connecticut, Hawaii, Minnesota, Missouri, New Jersey,
           New York, Texas, Washington and Puerto Rico Municipal Bonds

The following information is a summary of special risks affecting the states and
territory indicated, each of which could affect the bonds purchases by the Fund.
It does not purport to be complete or current and is based upon information and
judgments derived from public documents relating to such states and territory
and other sources. The Fund has not

verified any of this data.

California Bonds

California Constitutional and statutory provisions limit the taxing and spending
authority of California governmental entities and impair the ability of
California issuers to maintain debt service on their obligations. California's
economy has major components in high technology, trade, entertainment,
agriculture, manufacturing, tourism, construction and services. Unemployment in
the State has , but still exceeds the national average. Per capita income has
grown in recent years, and is greater than the national average. The State's
financial condition has improved since 1994, with increased revenues, slowdown
in the growth of social welfare programs and continued spending restraint and
economic growth. Revenues are expected to continue to increase during the
1998-99 fiscal year, with a corresponding increase in expenditures. The State's
budget reserve was $461 million as of June 30, 1997, and is estimated to be $329
million at June 30, 1998.

California's economy is expected to grow more slowly through 1998. The Asian
economic crisis is expected to have a dampening effect on the State's economy,
as exports will decrease, but increased needs for import services and lower
interest rates may help offset the negative impact. Rapidly growing exports to
Mexico and Latin America have been taking up some of the slack from Asia, but
could be reduced by global economic problems.

The taxing and spending authority of California's governmental entities has been
limited by the adoption of constitutional amendments. Proposition 13, enacted in
1978, constrains the fiscal condition of local governments by limited ad valorem
taxes on real property and restricting the ability of taxing entities to
increase real property and other taxes. In 1996, voters approved Proposition
218, which limits the ability of local government agencies to impose or raise
various taxes, fees, charges and assessments without voter approval, and
clarifies the right of local voters to reduce taxes, fees, assessments or
charges through local initiatives. Proposition 218 is generally viewed as
restricting the flexibility of local governments, and consequently has and may
further cause reductions in ratings of some cities and counties. The State is
also subject to an annual appropriations limit imposed by Article XIII B of the
State Constitution, which prohibits the state from spending the proceeds of tax
revenues, regulatory licenses, user charges or other fees beyond imposed
appropriations limits that are adjusted annually based on per capital personal
income and changes in population. Revenues that exceed the limitation are
measured over consecutive two-year periods, and any excess revenues are divided
equally between transfers to schools and community colleges and refunds to
taxpayers. Certain appropriations, including appropriations for the debt service
costs of bonds existing or authorized by January 1, 1979, or subsequently
authorized by voters, are subject to this limitation.

The effect of these various provisions upon the ability of California issuers to
pay interest and principal on their obligations remains unclear in many cases.
In any event, the effect may depend upon whether a particular California
Municipal Bond is a general or limited obligation bond (limited obligation bonds
generally being less affected by such changes) and on the type of security, if
any, provided for the bond. Future amendments to the California Constitution or
statutory changes also may harm the ability of the State or local issuers to
repay their obligations.

The failure of the State or other organizations or governmental agencies with
which the State electronically interacts, including State vendors and the
federal government, to be Year 2000 compliant may materially affect the State's
revenue and operations.

Connecticut Bonds

Manufacturing employment has been on a downward trend since the mid-1980's while
non-manufacturing employment has recovered most of its losses from its peak in
the late 1980s. Defense-related business remains important, although its
significance in the State's economy has declined considerably.

Connecticut has no constitutional limit on its power to issue obligations or
incur indebtedness, other than that it may only borrow for public purposes.
However, Connecticut law provides that no indebtedness payable from General Fund
tax receipts of the State shall be authorized by the General Assembly, except as
shall not cause the aggregate amount of (1) the total amount of indebtedness
payable from General Fund tax receipts authorized by the General Assembly 


                                       24
<PAGE>

but which have not been issued and (2) the total amount of such indebtedness
which has been issued and remains outstanding (with certain exceptions), to
exceed 1.6 times the total estimated General Fund tax receipts of the State for
the fiscal year in which any such authorization will become effective, as
estimated for such fiscal year by the joint standing committee of the General
Assembly having cognizance of finance, revenue and bonding.

In 1992, Connecticut voters approved a constitutional amendment which requires a
balanced budget for each year and imposes a cap on the growth of expenditures.
The General Assembly cannot authorize an increase in general budget expenditures
for any fiscal year above the amount of general budget expenditures for the
previous fiscal year by a percentage which exceeds the greater of the percentage
increase in personal income or the percentage increase in inflation. There is an
exception provided if the governor declares an emergency or the existence of
extraordinary circumstances and at least three-fifths of the members of each
house of the General Assembly vote to exceed the limit for purposes of such
emergency or extraordinary circumstances.

As of May 31, 1998, the estimated 1997-98 fiscal year General Fund revenues and
expenditures, according to the Comptroller's report, will result in a projected
surplus of $257.0 million. The adopted Midterm Budget Adjustments for fiscal
1998-99 anticipates a General Fund surplus of $19.6 million. Expenditures for
the payment of bonds, notes and other evidences of indebtedness are excluded
from the constitutional and statutory definitions of general budget
expenditures.

The State expects its Year 2000 plan to be completed on a timely basis, and is
monitoring the activities of its third-party vendors in developing and
implementing plans to address the Year 2000 issue. The failure to complete such
modifications and conversions in a timely manner may materially affect the
revenues and operations of the State.

Hawaii Bonds

The Constitution of the State of Hawaii empowers the issuance of four types of
bonds: general obligation bonds (all bonds for the payment of the principal and
interest for which the full faith and credit of the State or a political
subdivision are pledged and, unless otherwise indicated, including reimbursable
general obligation bonds); bonds issued under special improvements statutes;
revenue bonds (all bonds payable from revenues, or user taxes, or any
combination of both, of a public undertaking, improvement, system or loan
program); and special purpose revenue bonds (all bonds payable from rental or
other payments made or any issuer by a person pursuant to contract). All bonds
other than special purpose revenue bonds may be authorized by a majority vote of
the members of each House of the Hawaii Legislature. Special purpose revenue
bonds may be authorized by two-thirds vote of the members of each House of the
Hawaii Legislature.

The Hawaii Constitution provides that general obligation bonds may only be
issued by the State if such bonds at the time of issuance will not cause the
total amount of principal and interest payable in the current or any future
fiscal year, whichever is higher, on such bonds and on all outstanding general
obligation bonds in the current or any future fiscal year, whichever is higher,
to exceed 18.5% of the average general fund revenues of Hawaii in the three
fiscal years immediately before the issuance.

General Information. The construction and manufacturing industries have
experienced significant job losses in recent years, while unemployment rates
have increased or remained steady for five years. In contrast to the overall
strong performance of the U.S. economy in the 1990s, Hawaii's economic activity
has been flat during that time.

The failure of the State or other organizations or governmental agencies with
which the State electronically interacts, including State vendors and the
federal government, to be Year 2000 compliant may materially affect the State's
revenue and operations.


                                       25

Minnesota Bonds

Diversity and a significant natural resource base are two important
characteristics of Minnesota's economy. While the structure of the State's
economy parallels the structure of the United States economy as a whole, there
is some concentration in manfacturing categories. The importance of the State's
rich resource base for overall employment is apparent in the employment mix in
the non-durable goods industries.

The recession that began in 1990 was less severe in Minnesota than in the
national economy, and Minnesota's recovery was more rapid than the nation's. The
State's per capita income has generally remained above the national average in
spite of recessions and some difficult years in agriculture. Since 1995, the
State's monthly unemployment rate generally has been less than the national
unemployment rate.

The Minnesota Constitution places no limitation on the amount of debt which may
be authorized for permissible purposes. As of June 1, 1998, the outstanding
principal amount of general obligation bonds of the State was approximately $2.4
billion.

The Minnesota legislature has enacted a provision that interest on obligations
of Minnesota governmental units be included in the net income of individuals,
trusts and estates for Minnesota income tax purposes if a court determines that
Minnesota's exemption of such interest is unlawful in that it discriminates
against interstate commerce because interest on obligations of governmental
issuers in other states is so included. This provision applies to taxable years
that begin during or after the calendar year in which any such court decision
becomes final, no matter when the obligations were issued. Should a court so
rule, the value of securities held by the Fund, and thus the value of the Fund's
shares, would likely decrease, perhaps significantly.

The University of Minnesota, established as a separate entity by the Minnesota
Constitution, and various State agencies or instrumentalities established by the
Legislature, are authorized by law to issue various forms of obligations. These
obligations may be supported by the full faith and credit of the University and
the other issuers, or by various revenue pledges, or both. However, such
obligations are not debts of the State and the State is not required to provide
monies for their repayment.

The failure of the State or other organizations or governmental agencies with
which the State electronically interacts, including State vendors and the
federal government, to be Year 2000 compliant may materially affect the State's
revenue and operations.

Missouri Bonds

The State Constitution provides that the General Assembly may issue general
obligation bonds without voter approval solely for the purpose of (1) refunding
outstanding bonds or (2) upon the recommendation of the Governor, for a
temporary liability by reason of unforeseen emergency or of deficiency in
revenue in an amount not to exceed $1,000,000 for any one year and to be paid in
not more than five years or as otherwise specifically provided. When the
liability exceeds $1,000,000, the General Assembly, or the people by initiative,
may submit the proposition to incur indebtedness to the voters of the State, and
the bonds may be issued if approved by a majority of those voting.

The Constitution imposes in the Tax Limitation Amendment limits on the amount of
State taxes which may be collected by the State of Missouri in any fiscal year.
The limit is tied to total State revenues for fiscal year 1980-81, as defined in
the Tax Limitation Amendment, adjusted annually, in accordance with the formula
set forth in the Amendment, which adjusts the limit based on increases in the
average personal income of Missouri for certain designated periods. The details
of the Amendment are complex and clarification from subsequent legislation and
further judicial decisions may be necessary. If total State revenues exceed the
State revenue limit by more than one percent, the State is required to refund
the excess. The revenue limit can only be exceeded if the General Assembly
approves by a two-thirds vote of each House an emergency declaration by the
Governor. Revenues have exceeded the limit in each year since 1995, and the
state expects that the limit will again be exceeded in Fiscal Year 1998 by
approximately $118 million, which will trigger an income tax refund liability
under the Constitution.

The State's general revenue fund has had a surplus for five consecutive years,
increasing in fiscal 1997 to a balance 


                                       26
<PAGE>

of $1.71 billion.

To the extent that the payment of general obligation bonds issued by the State
of Missouri or a unit of local government in the Fund' portfolio is dependent on
revenues from the levy of taxes and such obligations have been issued subsequent
to the date of the Tax Limitation Amendment's adoption, November 4, 1980, the
ability of the State of Missouri or the appropriate local unit to levy
sufficient taxes to pay the debt service on such bonds may be affected.

Debt obligations of certain State and local agencies and authorities are not, by
the terms of their respective authorizing statutes, obligations of the State or
any political subdivision, public instrumentality or authority, county,
municipality or other state or local unit of government. The debt obligations of
such issuers are payable only from the revenues generated by the project or
program financed from the proceeds of the debt obligations they issue.

The State has a significant agricultural sector which may experience problems
comparable to those which are occurring in other states. To the extent that any
such problems intensify, there could be an adverse impact on the overall
economic condition of the State. Per capita income is slightly below the
national average.

Defense-related business plays an important role in Missouri's economy. To the
extent that changes in military appropriations are enacted by the United States
Congress, Missouri could be disproportionately affected.

The failure of the State or other organizations or governmental agencies with
which the State electronically interacts, including State vendors and the
federal government, to be Year 2000 compliant may materially affect the State's
revenue and operations.

New Jersey Bonds

After a period of strong growth in the mid-1980s, New Jersey as well as the rest
of the Northeast slipped into a slow-down well before the onset of the national
recession which officially began in July 1990. The onset of recession caused an
acceleration of New Jersey's job losses in construction and manufacturing, as
well as an employment downturn in such previously growing sectors as wholesale
trade, retail trade, finance, utilities, trucking and warehousing. The net
effect was a decline in the State's total nonfarm wage and salary employment,
followed by a recovery up to June 1997 of 97% of the jobs lost during the
recession.

Evidence of the State's improving economy can be found in increased homebuilding
and other areas of construction activity, rising consumer spending for new cars
and light trucks, substantial new job creation and a decline in the unemployment
rate. Looking further ahead, prospects for New Jersey appear favorable, although
a return to the pace of the 1980's is highly unlikely.

While personal income growth has been slower than the national average, per
capita income in New Jersey is second among the states.

The State ended fiscal 1997 with a general fund surplus and an undesignated fund
balance of $1.1 billion, and anticipates that it will again have a general fund
surplus at the end of fiscal 1998, with an expected undesignated fund balance of
$1 billion.

The New Jersey Constitution provides, in part, that no money shall be drawn from
the State treasury except for appropriations made by law and that no law
appropriating money for any State purpose shall be enacted if the appropriations
contained therein, together with all prior appropriations made for the same
fiscal period, shall exceed the total amount of the revenue on hand and
anticipated to be available to meet such appropriations during such fiscal
period, as certified by the Governor.

New Jersey's Local Budget Law imposes specific budgetary procedures upon
counties and municipalities ("local units"). Every local unit must adopt an
operating budget which is balanced on a cash basis, and items of revenue and
appropriation must be examined by the Director of the Division of Local
Government Services. State law also regulates the issuance of debt by local
units, by limiting the amount of tax anticipation notes that may be issued by
local units and requiring their repayment within 120 days of the end of the
fiscal year (six months in the case of the counties) in which issued. With
certain exceptions, no local unit is permitted to issue bonds for the payment of
current expenses or to pay


                                       27
<PAGE>

outstanding bonds, except with the approval of the Local Finance Board. Local
units may issue bond anticipation notes for temporary periods not exceeding in
the aggregate approximately ten years from the date of first issue. The debt
that any local unit may authorize is limited by statute.

The failure of the State or other organizations or governmental agencies with
which the State electronically interacts, including State vendors and the
federal government, to be Year 2000 compliant may materially affect the State's
revenue and operations.

New York Bonds

Circumstances adversely affecting the State's credit rating may directly or
indirectly affect the market value of bonds issued by the State's political
subdivisions and its Authorities to the extent that those entities depend, or
are perceived to depend, upon State financial assistance. Conversely, the fiscal
stability of the State is related to the fiscal stability of New York City and
of the Authorities. The State's experience has been that if New York City or any
of the Authorities suffers serious financial difficulty, the ability of the
State, New York City, the State's political subdivisions and the Authorities to
obtain financing in the public credit markets is adversely affected. This
results, in part, from the expectation that to the extent that any Authority or
local government experiences financial difficulty, it will seek and receive
State financial assistance. Moreover, New York City accounts for a substantial
portion of the State's population and tax receipts, so New York City's financial
integrity affects the State directly. Accordingly, if there should be a default
by New York City or any of the Authorities, the market value and marketability
of all New York State tax-exempt bonds could be adversely affected. This would
have an adverse effect on the net asset value and liquidity of the Fund, even
though securities of the defaulting entity may not be held by the Fund.

New York State. New York's economy features the services, trade, finance,
insurance and real estate sectors. The New York economy has expanded as it
continues to recover from the national recession of the early 1990s, although
growth remains somewhat slower than the national level. While new jobs have been
added, employment growth has been hindered in recent years by cutbacks in the
computer and instrument manufacturing, utility, defense and banking industries.
The State's economy is expected to continue to expand during 1998, although
employment growth is projected to slow. The unemployment rate is expected to
decrease, although it is projected to remain above the national rate. Per capita
income, which has historically exceeded the national average, is projected to
show moderate growth.

New York State's financial operations have improved during recent fiscal years.
During the period 1989-90 through 1991-92, the State incurred General Fund
operating deficits that were closed with receipts from the issuance of tax and
revenue anticipation notes. The national recession, followed by the lingering
economic slowdown in the New York and regional economy, resulted in repeated
shortfalls in receipts and three budget deficits during those years. Since
1992-93, however, the State has had balanced budgets, on a cash basis, in each
fiscal year.

The adopted 1998-99 budget projects an increase in General Fund disbursements of
7.1 percent over 1997-98 levels. State Funds (excluding federal grants)
disbursements are projected to increase by 9.8 percent from the prior fiscal
year. All Governmental Funds projected disbursements increase by 8.3 percent
over the prior fiscal year. The 1998-99 State Financial Plan is projected to be
balanced on a cash basis, with an estimated reserve for future needs of $761
million. The total amount of non-recurring resources included in the 1998-99
Financial Plan are projected to be $264 million.

The State has closed substantial projected budget gaps in recent years, and the
Executive Budget estimated General Fund budget gaps of $1.7 billion and $3.7
billion in 1999-00 and 2000-01, respectively. After application of reserves
created as part of the 1998-99 budget process, the 1999-00 gap is now expected
to be approximately $1.3 billion. Sustained growth in the State's economy could
contribute to closing projected budget gaps over the next several years;
however, the projections in 1999-00 currently assume actions to significantly
lower disbursements and achieve additional receipts.

There can be no assurance that the State's projections for tax and other
receipts for the 1998-99 fiscal year are not overstated and will not be revised
downward, or that disbursements will not be in excess of the amounts projected.
In addition, projections of State disbursements for future fiscal years may be
affected by uncertain factors relating to the economy and the financial
condition of the Authorities, New York City and other localities. In the event
that these 


                                       28
<PAGE>

factors affect, or are perceived to affect, the State's ability to meet its
financial obligations, the market value and marketability of its bonds also may
be adversely affected.

The State anticipates that its capital programs will be financed, in part,
through borrowings by the State and public authorities in the 1998-99 fiscal
year. The State expects to issue $528 million in general obligation bonds
(including $154 million for purposes of redeeming outstanding BANs) and $154
million in general obligation commercial paper. The Legislature has also
authorized the issuance of up to $419 million in Certificates of Participation
during the State's 1998-99 fiscal year for equipment purchases. The projection
of the State regarding its borrowings for the 1998-99 fiscal year may change if
circumstances require.

Borrowings by other public authorities pursuant to lease-purchase and
contractual-obligation financing for capital programs of the State are projected
to total approximately $2.9 billion in the 1998-99 fiscal year, including costs
of issuances, reserve funds, and other costs, net of anticipated refundings and
other adjustments.

Certain litigation pending or determined against the State or its officers or
employees could have a substantial or long-term adverse effect on State
finances. Among the more significant of these cases are those that involve:
challenges to the State's finance policies, claims challenging different aspects
of the State's social welfare programs, claims of racial segregation, and real
property claims.

The State is addressing Year 2000 data processing compliance issues, and is
focusing on mission-critical and high-priority computer systems.
"Mission-critical" systems are those impacting health, safety and welfare, while
"high-priority" applications are those critical for a state agency to fulfill
its mission and deliver services, but for which there are manual alternatives.
There can be no guarantee, however, that all of the State's mission-critical and
high-priority computer systems will be Year 2000 compliant and that the State's
operations or finances will not be adversely affected as a result.

Authorities. The fiscal stability of the State is related to the fiscal
stability of its Authorities, which generally are responsible for financing,
constructing and operating revenue-producing public facilities. Authorities are
not subject to the constitutional restrictions on the incurrence of debt which
apply to the State itself and may issue bonds and notes within the amounts
indicated in their legislative authorization. The State's access to the public
credit markets could be impaired, and the market price of its outstanding debt
may be adversely affected, if any of the Authorities were to default on their
respective obligations. As of December 31, 1997, there were outstanding
approximately $84 billion aggregate principal amount of bonds and bond
anticipation notes issued by 17 Authorities, only a portion of which were
guaranteed by the State or supported by the State through lease-purchase or
contractual-obligation financing arrangements or through moral obligation
provisions. While principal and interest payments on outstanding Authority
obligations normally are paid from revenues generated by projects of the
Authorities, in the past the State has had to appropriate large amounts to
enable certain Authorities (in particular, the New York State Urban Development
Corporation and the New York State Housing Finance Agency) to meet their
financial obligations. Further assistance to these Authorities may be required
in the future.

The Metropolitan Transportation Authority (the "MTA") oversees the operation of
New York City's bus and subway systems by its affiliates, the New York City
Transit Authority and the Manhattan and Bronx Surface Transit Operating
Authority (collectively, the "TA") and, through subsidiaries, operates certain
commuter rail and bus lines and a rapid transit line on Staten Island. Through
its affiliated agency, the Triborough Bridge and Tunnel Authority (the "TBTA"),
the MTA operates certain intrastate toll bridges and tunnels. The MTA has
depended and will continue to depend upon State, local government and TBTA
support to operate the mass transit portion of these operations because fare
revenues are insufficient. For the 1998-99 fiscal year, State assistance to the
MTA is estimated at approximately $1.3 billion.

State legislation accompanying the 1996-97 adopted State budget authorized the
MTA, TBTA and TA to issue an aggregate of $6.5 billion in bonds to finance a
portion of a new $11.98 billion MTA capital plan for the 1995 through 1999
calendar years (the "1995-99 Capital Program"). In July 1997, the Capital
Program Review Board approved the 1995-99 Capital Program, which supersedes the
overlapping portion of the MTA's 1992-96 Capital Program. This is the fourth
capital plan since the Legislature authorized procedures for the adoption,
approval and amendment of MTA capital programs and is designed to upgrade the
performance of the MTA's transportation systems by investing in new rolling
stock, maintaining replacement schedules for existing assets and bringing the
MTA system into a state of good repair. The 1995-99 Capital Program assumes the
issuance of an estimated $5.2 billion in bonds under this $6.5 billion 


                                       29
<PAGE>

aggregate bonding authority. The remainder of the plan is projected to be
financed through assistance from the State, the federal government, and the City
of New York, and from various other revenues generated from actions taken by the
MTA.

There can be no assurance that all the necessary governmental actions for future
capital programs will be taken, that funding sources currently identified will
not be decreased or eliminated, or that the 1995-99 Capital Program, or parts
thereof, will not be delayed or reduced. Should funding levels fall below
current projections, the MTA would have to revise its 1995-99 Capital Program
accordingly. If the 1995-99 Capital Program is delayed or reduced, ridership and
fare revenues may decline, which could, among other things, impair the MTA's
ability to meet its operating expenses without additional assistance.

The City of New York. The fiscal health of the State is closely related to the
fiscal health of its localities, particularly the City of New York (the "City"),
which has required and continues to require significant financial assistance
from the State.

In response to the City's fiscal crisis in 1975, the State took a number of
steps to assist the City in returning to fiscal stability. Among these actions,
the State created the Municipal Assistance Corporation for the City of New York
("MAC") to provide financing assistance to the City. The State also enacted the
New York State Financial Emergency Act for the City of New York which, among
other things, established the New York State Financial Control Board (the
"Control Board") to oversee the City's financial affairs. The State also
established the Office of the State Deputy Comptroller for New York City
("OSDC") in the Office of the State Comptroller to assist the Control Board in
exercising its powers and responsibilities.

The City operates under a four-year Financial Plan which is prepared annually
and is periodically updated. In 1986, the Control Board's powers of approval
over the City's Financial Plan were suspended when certain statutory conditions
were met. However, the Control Board, MAC and OSDC continue to exercise various
monitoring functions relating to the City's financial position and upon the
occurrence of certain events, including, but not limited to, a City operating
budget deficit of more than $100 million, the Control Board is required by law
to impose a "Control Period". The City submits its financial plans as well as
periodic updates to the Control Board for its review.

In 1997, the State created the New York City Transitional Finance Authority to
finance a portion of the City's capital program because the City was approaching
its State Constitutional general debt limit. Despite this additional financing
mechanism, the City currently projects that, if no further action is taken, it
will reach its debt limit in City fiscal year 1999-2000. Future developments
concerning the City or entities issuing debt for the benefit of the City, and
public discussions of such developments, as well as prevailing market conditions
and securities credit ratings, may affect the ability or cost to sell securities
issued by the City or such entities and may also affect the market for their
outstanding securities.

Although the City has balanced its budget since 1981, estimates of the City's
revenues and expenditures are based on various assumptions and contingencies.
Unforeseen developments and changes in major assumptions could significantly
affect the City's ability to balance its budget as required by State law and t
meet its annual cash flow and financing requirements.

The staffs of the Control Board, OSDC and City Comptroller issue periodic
reports on the City's Financial Plans. Recent reports note that the City had a
substantial surplus in City fiscal year 1996-97 and indicate that the City
projects another substantial surplus for City fiscal year 1997-98. While several
sectors of the City's economy have expanded recently, especially tourism and
business and professional services, City tax revenues remain heavily dependent
on the continued profitability of the securities industry and the national
economy. Recent reports have indicated that the City's long-term expenditure
growth is not in line with recurring revenue growth and that, consequently,
substantial budget gaps between forecast revenues and expenditures that must be
closed with reduced expenditures and/or increased revenues are likely in future
years.

Other Localities. Certain localities in addition to the City have experienced
financial problems and have received additional State assistance during the last
several State fiscal years. The potential impact on the State of such actions by
localities is not included in the projections of the State receipts and
disbursements for the State's 1998-99 fiscal year.


                                       30
<PAGE>

Municipalities and school districts have engaged in substantial short-term and
long-term borrowing. In 1995, the total indebtedness of all localities in the
State other than the City was approximately $20.0 billion; a small portion
(approximately $77 million) of this indebtedness represented borrowing to
finance budgetary deficits and was issued pursuant to enabling State
legislation. Twenty-one localities had outstanding indebtedness for deficit
financing at the close of their fiscal years ending in 1996.

From time to time, Federal expenditure reductions could reduce, or in some cases
eliminate, Federal funding of some local programs and accordingly might impose
substantial increased expenditure requirements on affected localities. If the
State, the City or any of the Authorities were to suffer serious financial
difficulties jeopardizing their respective access to the public credit markets,
the marketability of notes and bonds issued by localities within the State could
be adversely affected. Localities may also face unanticipated problems resulting
from certain pending litigation, judicial decisions and long-range economic
trends. Other large-scale problems, such as declining city populations,
increasing expenditures, and other economic trends could adversely affect
localities, necessitating State assistance.

Puerto Rico Bonds

Puerto Rico's manufacturing sector has become more diversified as industrial
development has become more capital intensive and more dependent on skilled
labor. The service sector, including wholesale and retail trade, finance,
insurance and real estate, also plays a major role in the economy. The service
sector ranks second only to manufacturing in contribution to the gross domestic
product and leads all sectors in providing employment. In recent years, the
service sector has experienced significant growth in response to and paralleling
the expansion of the manufacturing sector. Growth in construction and tourism
also contributed to contributed increased economic activity in fiscal 1997.

Much of the development of the manufacturing sector in Puerto Rico to date can
be attributed to various federal and Commonwealth tax incentives, most notably
Section 936 of the Internal Revenue Code (the "Code"), which allows companies
with operations in Puerto Rico and other U.S. territories to receive a credit to
be used against U.S. tax on certain income from operations and the
Commonwealth's Industrial Incentives Program. However, in 1996 amendments were
passed that phase out Section 936 tax credits over ten years for existing
claimants and eliminate it for corporations without established operations after
October 1995. The long-term effects on the Puerto Rico economy of the repeal of
section 936 cannot yet be determined, although the repeal is not expected to
have material adverse effects on the Commonwealth's economy in the short- or
medium-term. The Commonwealth also needs to address its substantial unfunded
pension liabilities to its two main public pension systems, which together total
approximately $6 billion.

Puerto Rico's economy has continued to expand for over a decade, with almost
every sector participating and resulting in record levels of employment
(although Puerto Rico's unemployment rate has continued to exceed the average
for the United States). Factors behind this expansion included
Commonwealth-sponsored economic development programs, periodic declines in the
exchange value of the United States dollar, increases in the level of federal
transfers and the relatively low cost of borrowing. Personal income, both
aggregate and per capita, has increased consistently each year since 1985, but
per capita income remains lower than in the United States.

The Commonwealth's general fund has had a positive cash balance in recent years,
and was forecast to have a balance of $38 million at the end of fiscal 1998. The
balance at the end of fiscal 1997 was $127.5 million.

The Constitution of Puerto Rico provides that public debt of the Commonwealth
will constitute a first claim on available Commonwealth revenues. Public debt
includes general obligation bonds and notes of the Commonwealth and any payments
required to be made by the Commonwealth under its guarantees of bonds and notes
issued by its public instrumentalities.

The Constitution of Puerto Rico also provides that direct obligations of the
Commonwealth evidenced by full faith and credit bonds or notes shall not be
issued if the amount of the principal of and interest on such bonds and notes
and on all such bonds and notes theretofore issued which is payable in any
fiscal year, together with any amount paid by the Commonwealth in the preceding
fiscal year on account of bonds or notes guaranteed by the Commonwealth, exceeds
15% of the average annual revenues raised under the provisions of Commonwealth
legislation and covered into the Treasury of Puerto Rico (principally income
taxes, property taxes and excise taxes) in the two fiscal years preceding the
then current fiscal year.


                                       31

The Commonwealth has historically maintained a fiscal policy providing for a
prudent relationship between the growth of public sector debt and the growth of
the economic base required to service that debt. However, in recent years there
have been higher levels of public sector debt compared to the growth in nominal
gross product. These higher levels are due to the increase during fiscal 1996
and 1997 in the amount of debt incurred to finance infrastructure projects. This
trend is expected to continue during the next few fiscal years as the level of
public sector capital investment remains high.

The failure of the Commonwealth or other organizations or governmental agencies
with which the Commonwealth electronically interacts, including Commonwealth
vendors and the federal government, to be Year 2000 compliant may materially
affect the Commonwealth's revenue and operations.

Texas Bonds

The State Comptroller of Public Accounts has predicted that the overall State
economy will slightly outpace national economic growth in the long term. The
service-producing sectors (which include transportation, public utilities,
finance, insurance, real estate, trade, services and government) are the major
sources of job growth in Texas, although the rate of growth of goods-producing
jobs has been nearly as fast as that of service-producing jobs since 1994.
Construction has been the State's fastest growing industry in recent years. The
State now ranks second in manufacturing employment, and job growth in
manufacturing is expected to continue. The predominant manufacturing sectors are
high technology and petroleum-related manufacturing.

Texas has added more jobs than any other state during the 1990s, and the State's
unemployment rate has declined for five consecutive years. While job growth has
been strong, personal income growth per capita has been slower, and per capita
income remains below the national average.

Due to the State's expansion in Medicaid spending and other Health and Human
Services programs requiring federal matching revenues, federal receipts were the
State's main revenue source during fiscal year 1997. Sales tax, which had been
the main source of revenue for 12 years prior to 1993, was second. Licenses,
fees and permits, the motor fuels tax and other excise taxes also are important
sources of revenue. The State has no personal or corporate income tax, although
the State does impose a corporate franchise tax based on the amount of a
corporation's capital and "earned surplus", which includes corporate net income
and officers' and directors' compensation.

The State's debt position has grown in recent years, and although much of the
indebtedness of the State is designed to be self-supporting, the State has begun
to issue more debt supported by the general revenue fund.

The State Constitution prohibits the State from levying ad valorem taxes on
property for general revenue purposes. The State Constitution also limits the
rate of growth of appropriations from tax revenues not dedicated by the
Constitution during any biennium to the estimated rate of growth for the State's
economy. The Legislature may avoid the constitutional limitation if it finds, by
a majority vote of both Houses, that an emergency exists. The State Constitution
authorizes the Legislature to provide by law for the implementation of this
restriction, and the Legislature, pursuant to such authorization, has defined
the estimated rate of growth in the State's economy to mean the estimated
increase in State personal income.

In 1997, voters approved a constitutional amendment that prohibits the
legislature from authorizing additional state debt payable from general revenues
if the resulting annual debt service exceeds five percent of an amount equal to
the average amount of general revenue for the three immediately preceding years,
excluding revenues constitutionally dedicated for purposes other than payment of
debt service.

The State is focusing its Year 2000 efforts on mission-critical computer systems
(those that impact public health, public safety and revenue
collection/distribution), and currently believes that most will be operable in
the Year 2000. There is no guarantee, however, that the State systems and
systems of other entities on which the State's system relies will be Year 2000
compliant. Failure of any systems to be Year 2000 compliant will have an adverse
effect on the State's revenues and operations.

Washington Bonds


                                       32
<PAGE>

On a combined basis, the aerospace, timber and food processing industries employ
about 9% of the State's non-farm workers. Agriculture, combined with food
processing, is the State's most important industry .

The State's manufacturing base includes aircraft manufacture, which comprised
approximately 25% of total manufacturing in 1995. The aerospace industry
currently represents approximately 8% of all taxable business income generated
in the State. The Boeing Company is the State's largest employer. While the
primary activity of Boeing is the manufacture of commercial aircraft, Boeing has
played leading roles in the aerospace and military missile programs of the
United State and has undertaken a broad program of diversification activities
including Boeing Information and Support Services. Although Boeing has dominated
manufacturing employment, other manufacturers have experienced growth, thus
reducing Boeing's percentage of total manufacturing jobs in the State. The most
significant growth in manufacturing jobs, other than aerospace, has been in high
technology-based companies.

The State ranks fourth among all states in the percentage of its work force
employed in technology-related industries and ranks third among the largest
software development centers.

Forest products rank second behind aerospace in value of total production. A
continued decline in overall production during the next few years is expected
due to federally imposed limitations on the harvest of old-growth timber and the
inability to maintain the recent record levels of production increases.

International trade plays an important role in the State's employment base, as
one in six jobs in the State is related to international trade. The State's
trade levels depend largely on national and world (rather than local) economic
conditions, including consumer demands. The impact of the Asian financial crisis
on the Washington economy is expected to be disproportionately high due to the
State's above-average dependence on trade with the affected countries.
Washington expects a slowdown in employment growth as a result of slower U.S.
economic growth, the Asian financial crisis and mild downturn in aerospace
unemployment.

While personal income growth, which has been strong in recent years, is expected
to slow, it is projected to continue to outpace average U.S. personal income
growth.

For the 1997-99 biennium, General Fund-State revenues are estimated to finish at
$19.9 billion. The General Fund is projected to end the 1997-99 biennium with a
$820 million fund balance.

As of July 1, 1995, Initiative 601, which was voted into law in November 1993,
limits increases in General Fund-State government expenditures to the three-year
average rate of population and inflation growth. Thus far, Initiative 601 has
not had a restrictive impact on the State's budget.

Washington's Constitution, as interpreted by the State Supreme Court, prohibits
the imposition of net income taxes. For the fiscal year ending June 30, 1997,
approximately 76.1% of the State's tax revenues derived from general and
selective sales and gross receipts taxes.

With certain exceptions, the amount of State general obligation debt which may
be incurred is limited by constitutional and statutory restrictions. The
limitations in both cases are imposed by prohibiting the issuance of new debt if
the new debt would cause the maximum annual debt service on all thereafter
outstanding general obligation debt to exceed a specified percentage of the
arithmetic mean of general State revenues for the preceding three years. These
are limitations on the incurrence of new debt and are not limitations on the
amount of debt service which may be paid by the State in future years.

The State has taken action to ensure that its computer systems are Year 2000
compliant. It does not expect the cost of bringing its systems into compliance
to be material or that its operations will be materially impaired with the
advent of the Year 2000. It is possible, however, that costs will exceed the
State's expectations. Also, the State cannot quantify potential losses due to
systems disruption, and the amount of any potential recovery by the State. The
failure of the State or other organizations or governmental agencies with which
the State electronically interacts to be Year 2000 compliant may materially
affect the State's revenue and operations.

                                Past Performance

Each Fund computes the average annual rate of total return for each class during
specified periods that would equate the initial amount invested to the ending
redeemable value of such investment by adding one to the computed average annual
total return, raising the sum to a power equal to the number of years covered by
the computation and multiplying the result by $1,000 which represents a
hypothetical initial investment. The calculation assumes deduction of the
maximum sales charge from the initial amount invested and reinvestment of all
income dividends and capital gains distributions on the reinvestment dates at
prices calculated as stated in the Prospectus. The ending redeemable value is
determined by assuming a complete redemption at the end of the period(s) covered
by the average annual total return computation.

In calculating total returns for Class A shares, the current maximum sales
charge of 4.75% (as a percentage of the offering price) is deducted from the
initial investment (unless the return is shown at net asset value). For Class B
shares (National Fund only), the payment of the applicable CDSC (5.0% prior to
the first anniversary of purchase, 4.0% prior to the second anniversary of
purchase, 3.0% prior to the third and fourth anniversaries of purchase, 2.0%
prior to the fifth anniversary of purchase, 1.0% prior to the sixth anniversary
of purchase and no CDSC on and after the sixth anniversary of purchase) is
applied to the National Fund's investment result for that class for the time
period shown (unless the total return is shown at net asset value). For Class C
shares, the 1.0% CDSC is applied to the applicable Fund's investment result for
that class for the time period shown prior to the first anniversary of purchase
(unless the total return is shown at net asset value). Total returns also assume
that all dividends and capital gains distributions during the period are
reinvested at net asset value per share, and that the investment is redeemed at
the end of the period.

The total returns for the Class A shares of the National, New York, Texas, New
Jersey, Connecticut, Missouri, Hawaii, Washington, Minnesota and California Fund
of the Fund using the computation method described above for the one-year period
ended on September 30, 1998 were as follows: 4.40%, 3.80%, 4.10%, 4.00%, 3.20%,
2.60%, 3.50%, 4.30% 3.00% and 3.70% respectively. The average annual compounded
rates of total return for the National, New York, Texas, New Jersey,
Connecticut, Missouri, Hawaii, Washington and California Fund for the five years
ending on September 30, 1998 were as follows: 4.66%, 3.78%, 5.04%, 4.81%, 4.41%,
4.14%, 4.35%, 4.95% and 3.75% respectively. The average annual compounded rates
of total return for the National, New York, Texas, New Jersey, Connecticut,
Missouri, Hawaii, Washington, Minnesota and California Fund for ten years or
life of the Fund were as follows: 7.65%, 7.13%, 7.95 %, 7.68 %, 7.17%, 6.96%,
6.66%, 7.17 %, 7.02% and 7.36% respectively. These five and ten year total
returns included the California Fund' Class A predecessor until July 15, 1996.

The total return for Class B Shares of the National Fund for the one year period
ended September 30, 1998 was 7.25%.

The total return for Class C Shares of the National, New York and California
Fund for the one year period ending September 30, 1998 were 8.80%, 8.33% and
8.09 % and life 9.15%, 8.15% and 8.33% respectively.

Each Fund's yield quotation for each class is based on a 30-day period ended on
a specified date, computed by dividing the Fund' net investment income per share
earned during the period by the Fund' maximum offering price per share on the
last day of the period. This is determined by finding the following quotient:
Take the Fund' dividends and interest earned during the period minus its
expenses accrued for the period (net of reimbursements) and divide by the
product of (i) the average daily number of Fund shares outstanding during the
period that were entitled to receive dividends and (ii) the Fund' maximum
offering price per share on the last day of the period. To this quotient add
one. This sum is multiplied by itself five times. Then, one is subtracted from
the product of this multiplication and the remainder is multiplied by two. Yield
for the Class A shares reflects the deduction of the maximum initial sales
charge, but may also be shown based on the Fund's net asset value per share.
Yields for Class B and C shares do not reflect the deduction of the CDSC. For
the 30-day period ended September 30, 1998, the yields for Class A shares of the
National, California, Connecticut, Missouri, New Jersey, New York, Texas,
Hawaii, Washington and Minnesota Funds were 4.15%, 4.02%,4.28%, 3.92%, 4.05%,
4.28%, 4.19%, 4.04%, 4.46%, and 4.46%, respectively.

Each Fund's tax-equivalent yield for each class is computed by dividing that
portion of the class' yield (as determined above) which is tax exempt by one
minus a stated income tax rate (National 7.14%; California 8.16%; Connecticut
7.31%; Missouri 7.66%; New Jersey 7.36%; New York 7.69%; Texas 6.75%; Hawaii
7.83%; Washington 7.77% and


                                       34
<PAGE>

Minnesota 7.67%) and adding the product to that portion, if any, of the class'
yield that is not tax exempt. For the 30-day period ended on September 30, 1998,
the tax-equivalent yields for Class A shares of the National, California,
Connecticut, Missouri, New Jersey, New York, Texas, Hawaii, Washington and
Minnesota Fund were 4.44%, 4.38%, 4.62%, 4.25%, 4.37%, 4.64%, 4.49%, 4.38%,
4.84% and 4.83%, respectively.

It is important to remember that these figures represent past performance and an
investor should be aware that the investment return and principal value of a
Fund investment will fluctuate so that an investor's shares, when redeemed, may
be worth more or less than their original cost. Therefore, there is no assurance
that this performance will be repeated in the future.

Item 24.    Persons Controlled by or Under Common Control with Registrant

            None.

Item 25.    Indemnification

            Registrant is incorporated under the laws of the State of Maryland
            and is subject to Section 2-418 of the Corporations and Associations
            Article of the Annotated Code of the State of Maryland controlling
            the indemnification of directors and officers. Since Registrant has
            its executive offices in the State of New York, and is qualified as
            a foreign corporation doing business in such State, the persons
            covered by the foregoing statute may also be entitled to and subject
            to the limitations of the indemnification provisions of Section
            721-726 of the New York Business Corporation Law.

            The general effect of these statutes is to protect officers,
            directors and employees of Registrant against legal liability and
            expenses incurred by reason of their positions with the Registrant.
            The statutes provide for indemnification for liability for
            proceedings not brought on behalf of the corporation and for those
            brought on behalf of the corporation, and in each case place
            conditions under which indemnification will be permitted, including
            requirements that the officer, director or employee acted in good
            faith. Under certain conditions, payment of expenses in advance of
            final disposition may be permitted. The By-laws of Registrant,
            without limiting the authority of Registrant to indemnify any of its
            officers, employees or agents to the extent consistent with
            applicable law, make the indemnification of its directors mandatory
            subject only to the conditions and limitations imposed by the
            above-mentioned Section 2-418 of Maryland law and by the provisions
            of Section 17(h) of the Investment Company Act of 1940 as
            interpreted and required to be


                                       1
<PAGE>

            implemented by SEC Release No. IC-11330 of September 4, 1980.

            In referring in its By-laws to, and making indemnification of
            directors subject to the conditions and limitations of, both Section
            2-418 of the Maryland law and Section 17(h) of the Investment
            Company Act of 1940, Registrant intends that conditions and
            limitations on the extent of the indemnification of directors
            imposed by the provisions of either Section 2-418 or Section 17(h)
            shall apply and that any inconsistency between the two will be
            resolved by applying the provisions of said Section 17(h) if the
            condition or limitation imposed by Section 17(h) is the more
            stringent. In referring in its By-laws to SEC Release No. IC-11330
            as the source for interpretation and implementation of said Section
            17(h), Registrant understands that it would be required under its
            By-laws to use reasonable and fair means in determining whether
            indemnification of a director should be made and undertakes to use
            either (1) a final decision on the merits by a court or other body
            before whom the proceeding was brought that the person to be
            indemnified ("indemnitee") was not liable to Registrant or to its
            security holders by reason of willful malfeasance, bad faith, gross
            negligence, or reckless disregard of the duties involved in the
            conduct of his office ("disabling conduct") or (2) in the absence of
            such a decision, a reasonable determination, based upon a review of
            the facts, that the indemnitee was not liable by reason of such
            disabling conduct, by (a) the vote of a majority of a quorum of
            directors who are neither "interested persons" (as defined in the
            1940 Act) of Registrant nor parties to the proceeding, or (b) an
            independent legal counsel in a written opinion. Also, Registrant
            will make advances of attorneys' fees or other expenses incurred by
            a director in his defense only if (in addition to his undertaking to
            repay the advance if he is not ultimately entitled to
            indemnification) (1) the indemnitee provides a security for his
            undertaking, (2) Registrant shall be insured against losses arising
            by reason of any lawful advances, or (3) a majority of a quorum of
            the non-interested, non-party directors of Registrant, or an
            independent legal counsel in a written opinion, shall determine,
            based on a review of readily available facts, that there is reason
            to believe that the indemnitee ultimately will be found entitled to
            indemnification.

            Insofar as indemnification for liability arising under the
            Securities Act of 1933 may be permitted to directors, officers and
            controlling persons of the Registrant pursuant to the foregoing
            provisions, or otherwise, the Registrant has been advised that in
            the opinion of the Securities and Exchange Commission such
            indemnification is against public policy as expressed in the Act and
            is, therefore, unenforceable. In the event that a claim for
            indemnification against such liabilities (other than the payment by
            the Registrant of expense incurred or paid by a director, officer or
            controlling person of the Registrant in the successful defense of
            any action, suit or proceeding) is asserted by such director,
            officer or controlling person in connection with the securities
            being registered, the Registrant will, unless in the opinion of its
            counsel the matter has been settled by controlling precedent, submit
            to a court of appropriate jurisdiction the question whether such
            indemnification by it is against public policy as expressed in the
            Act and will be governed by the final adjudication of such issue.

            In addition, Registrant maintains a directors' and officers' errors
            and omissions liability insurance policy protecting directors and
            officers against liability for breach of duty, negligent act, error
            or omission committed in their capacity as directors or officers.
            The policy contains certain exclusions, among which is exclusion
            from coverage for active or deliberate dishonest or fraudulent acts
            and exclusion for fines or penalties imposed by law 


                                       2

            or other matters deemed uninsurable.
