    RISK/RETURN SUMMARY
 
    INVESTMENT OBJECTIVE              The Fund seeks to provide investors with long-term capital
                                      appreciation. The production of any current income is
                                      incidental.
 
    PRINCIPAL                         The Fund invests primarily in equity securities of foreign
    INVESTMENT STRATEGY               issuers located in at least three countries outside the
                                      United States which are likely to have rapid growth in
                                      revenues and earnings and potential for above-average
                                      capital appreciation. Equity securities include common and
                                      preferred stocks, securities convertible into common stocks
                                      and securities like rights and warrants that have common
                                      stock characteristics. The Fund seeks companies that have
                                      the potential to grow faster than other companies in their
                                      respective equity markets and are priced at attractive
                                      valuation levels.
 
    PRINCIPAL                         The Fund's share prices will fluctuate with changes in the
    INVESTMENT RISKS                  market value of the Fund's securities. Stocks are subject to
                                      market, economic and business risks that cause their prices
                                      to fluctuate. Foreign securities are subject to currency,
                                      information and political risks. The Fund is also subject to
                                      the risk that the Adviser's judgment about the above-average
                                      growth potential of particular stocks is incorrect. When you
                                      sell Fund shares, they may be worth less than what you paid
                                      for them. You can lose money by investing in the Fund.
    
   
    WHO MAY                           Consider investing in the Fund if you:
    WANT TO INVEST?                   [ ] ARE SEEKING A LONG-TERM GOAL SUCH AS RETIREMENT

   RISK/RETURN SUMMARY AND FUND EXPENSES
 
- -
 
   
   The chart on this page shows the Fund's annual returns over the past three
   years and provides some indication of the risks of investing in the Fund by
   showing how its performance has varied from year to year. The table below
   compares the Fund's performance over time to that of the Lipper International
   Fund Average ("LIFA") and the Morgan Stanley EAFE Index ("MS EAFE"). The MS
   EAFE is widely recognized, unmanaged index composed of common stocks from
   Europe, Australasia and the Far East. The LIFA represents an index of
   performance of returns of international equity mutual funds as tracked by
   Lipper, Inc. Of course, past performance does not indicate how the Fund will
   perform in the future. Both the chart and table assume reinvestment of
   dividends and distributions.

   EXPENSE EXAMPLE
   Use the example shown here
   to compare fees and
   expenses with those of
   other funds. It
   illustrates the amount of
   fees and expenses you
   would pay, assuming the
   following:
    
 
   - $10,000 investment
   - 5% annual return
   - redemption at the end of
     each period
   - no changes in the Fund's
     operating expenses
 
   Because this example is
   hypothetical and for
   comparison only, your
   actual costs may be higher
   or lower.

   INVESTMENT OBJECTIVES, STRATEGIES AND RISKS
 
   INVESTMENT OBJECTIVES AND PRINCIPAL STRATEGIES
 
   The Fund seeks long-term capital appreciation. To achieve its investment
   objective, the Fund invests primarily in the equity securities of foreign
   issuers. The Fund's investment objective may not be changed without
   shareholder approval. There is no assurance that the Fund will achieve its
   investment objective.
 
   
   Under normal circumstances, the Fund will invest at least 65% of its total
   assets in the equity securities of companies located in at least three
   countries outside the U.S. which the Adviser believes are likely to have
   rapid growth in revenues and earnings and potential for above-average capital
   appreciation.
    
 
   In choosing investments, the Adviser considers a number of factors,
   including:
   - a company's potential to grow faster than other companies in its respective
     equity market;
   - valuation levels;
   - the political stability and economic outlook of countries and regions; and
   - the prudent allocation among countries and regions to reduce volatility in
     the Fund's portfolio.
 
   The Fund intends to diversify its investments across different countries, but
   the percentage of Fund assets invested in particular countries or regions
   will change from time to time based on the Adviser's judgment. The Fund
   intends to invest in the securities of companies located in developed
   countries and, to a lesser extent, those located in emerging markets.
 
   
   As a defensive tactic in unusual market conditions, the Fund may temporarily
   invest up to 100% of its assets in money market instruments. This could
   potentially keep the Fund from achieving its goal.
    
 
   
   RISK FACTORS
    
 
   Investing in the Fund involves the following risks, listed in the order of
   importance. An investment in the Fund is not a bank deposit, is not insured
   or guaranteed by the Federal Deposit Insurance Corporation or any other
   government agency.
 
   MARKET RISK The market value of a security may move up and down, sometimes
   rapidly and unpredictably. These fluctuations, which are often referred to as
   "volatility", may cause a security to be worth less than it was worth at an
   earlier time. Market risk may affect a single issuer, industry, sector of the
   economy or the market as a whole. Market risk is common to most
   investments -- including stocks and bonds and the mutual funds that invest in
   them.
 
   
   FOREIGN SECURITIES RISK A fund that invests outside the U.S. carries
   additional risks that include:
 
        - CURRENCY RISK Fluctuations in exchange rates between the U.S. dollar
          and foreign currencies may negatively affect an investment. Adverse
          changes in exchange rates may erode or reverse any gains produced by
          foreign-currency denominated investments and may widen any losses. The
          Fund may, but is not required to, seek to reduce currency risk by
          hedging part or all of its exposure to various foreign currencies.
 
        - INFORMATION RISK Key information about an issuer, security or market
          may be inaccurate or unavailable.

   INVESTMENT OBJECTIVES, STRATEGIES AND RISKS
- -
 
   
        - POLITICAL RISK Foreign governments may expropriate assets, impose
          capital or currency controls, impose punitive taxes or nationalize a
          company or industry. Any of these actions could have a severe effect
          on security prices and impair the Fund's ability to bring its capital
          or income back to the U.S. Other political risks include economic
          policy changes, social and political instability, military action and
          war.
    
 
   
        - ACCESS RISK The risk that some countries may restrict the Fund's
          access to investments or offer terms that are less advantageous than
          those for local investors. This could limit the attractive investment
          opportunities available to the Fund.
    
 
   
   FUND AND MANAGEMENT RISK The Fund invests in growth stocks and the Fund's
   price may decline if the market favors other types of stocks. If the Adviser
   is incorrect in its assessment of the growth prospects of the securities it
   holds, the value of the Fund's shares may decline.

   FUND MANAGEMENT
 
   THE INVESTMENT ADVISER
 
   
   Gabelli Funds, LLC (the "Adviser"), One Corporate Center, Rye, NY 10580 is a
   limited liability company organized in 1999 after a reorganization of the
   predecessor, Gabelli Funds, Inc., which was formed in 1980. As of December
   31, 1998, Gabelli Funds, LLC and its affiliates manage more than $16.3
   billion in assets. Through its portfolio management team, Gabelli Funds, LLC
   makes the day-to-day investment decisions and continuously reviews,
   supervises and administers the Fund's investment programs.
    
 
   For these advisory services, the Adviser was paid a fee of 1.00% of average
   net assets during the fiscal year ended December 31, 1998. Any portion of the
   total fees received by the Adviser may be used by the Adviser to provide
   shareholder and administrative services.
 
   
   THE PORTFOLIO MANAGER
    
 
   Mr. Caesar M.P. Bryan is primarily responsible for the day-to-day management
   of the Fund. Mr. Bryan has been a Senior Vice President and Portfolio Manager
   with GAMCO Investors, Inc., a wholly-owned subsidiary of the Adviser, and
   Portfolio Manager of the Gabelli Gold Fund, Inc. since May 1994. Mr. Bryan
   served as Senior Vice President of Lexington Management Corporation from 1986
   until May 1994.
 
   THE DISTRIBUTOR
 
   Gabelli & Company, Inc. is the Fund's distributor. Its address is One
   Corporate Center, Rye, NY 10580.
 
   The Statement of Additional Information has more detailed information about
   the Adviser and other service providers.
 
   
   YEAR 2000. As the year 2000 approaches, an issue has emerged regarding how
   the software used by the Fund's service providers can accommodate the date
   "2000." Failure to adequately address this issue could result in major
   systems or process failures which could disrupt the Fund's operations. The
   Adviser is in the process of working with the Fund's service providers to
   prepare for the year 2000. Based on information currently available, the
   Adviser does not expect that the Fund will incur significant operating
   expenses or be required to incur material costs to be year 2000 compliant.
   The Fund cannot guarantee, however, that all year 2000 issues will be
   identified and corrected by January 1, 2000, and any non-compliant computer
   system could hurt key Fund operations, such as shareholder servicing, pricing
   and trading. In addition, the Year 2000 problem may adversely affect the
   companies in which the Fund invests, particularly companies in foreign
   countries. For example, these companies may incur substantial costs to
   correct the problem. To the extent that the impact on a Fund holding is
   negative, it could seriously affect the Fund's performance.

   SHAREHOLDER INFORMATION
 
   PRICING OF FUND SHARES
 
   HOW NAV IS CALCULATED
 
   The NAV is calculated by
   adding the total value of
   the Fund's investments and
   other assets, subtracting
   its liabilities and then
   dividing that figure by the
   number of outstanding
   shares of the Fund:
 
              NAV =
   Total Assets - Liabilities
 
  ----------------------------
        Number of Shares
           Outstanding
 
   You can find the Fund's NAV
   daily in the Wall Street
   Journal and other
   newspapers or by calling
   1-800-GABELLI
   (800-422-3554).
   
                                          The net asset value, or NAV, of the
                                          Fund's Class AAA shares is determined
                                          and such shares are priced at the
                                          close of regular trading of the New
                                          York Stock Exchange, normally at 4:00
                                          p.m., eastern time, on days the New
                                          York Stock Exchange is open. Your
                                          order for purchase, sale or exchange
                                          of shares is priced at the next NAV
                                          calculated after your order is
                                          received by the Fund. This is what is
                                          known as the offering price.
    
 
                                          Fund securities are valued as of the
                                          close of trading on the primary
                                          exchange on which they trade. The
                                          Fund's securities are generally valued
                                          at current market prices. If market
                                          quotations are not available, prices
                                          will be based on the average of the
                                          latest bid and asked quotations for
                                          such securities prior to the valuation
                                          time, or the latest bid price if asked
                                          prices are not available. Debt
                                          securities with remaining maturities
                                          of 60 days or less will be valued at
                                          amortized cost, which the Board of
                                          Directors believes represents fair
                                          value.
 
                                          Some Fund securities may be listed on
                                          foreign exchanges that are open on
                                          days (such as U.S. holidays) when the
                                          Fund does not compute its NAV. This
                                          could cause the value of the Fund's
                                          portfolio investments to be affected
                                          on days when you cannot buy or sell
                                          shares.
 
   PURCHASING, SELLING AND EXCHANGING SHARES
 
   Information about purchasing, selling and exchanging your shares is contained
   in a separate document called the Owner's Manual. If you have not received
   it, please contact your broker or financial consultant or the Fund at the
   number listed on the back page of this Prospectus. The Owner's Manual is
   considered an integral part of this Prospectus.
 
   DISTRIBUTION ARRANGEMENTS
 
   
   The Fund has adopted a distribution plan pursuant to Rule 12b-1 under the
   1940 Act which authorizes payments by the Fund of .25% of the average daily
   net assets attributable to Class AAA shares of the Fund to compensate the
   Distributor and other dealers and investment representatives for services and
   expenses relating to the sale and distribution of the Fund's shares. Rule
   12b-1 fees are paid from Fund assets on an ongoing basis, and increase the
   cost of your investment and may cost you more than paying other types of
   sales charges.

   SHAREHOLDER INFORMATION
 
   
   DIVIDENDS, DISTRIBUTIONS AND TAXES
    
   Any income the Fund receives in the form of interest or dividends is paid
   out, less expenses, to its shareholders. The Fund declares and pays dividends
   from net investment income and capital gains, if any, on an annual basis.
 
   Dividends and distributions are treated in the same manner for federal income
   tax purposes whether you receive them in cash or in additional shares.
 
   
   The Fund expects that its dividends will primarily consist of net investment
   income and, if any, short-term and long-term capital gains. Fund
   distributions are taxed based on the length of time the Fund holds its
   assets, regardless of how long you have held Fund shares. Distributions from
   net investment income and short-term capital gains are taxable as ordinary
   income. Such distributions are taken into account for tax purposes in the
   year in which they are declared, even if they appear on your account
   statement the following year. Long-term capital gain distributions are
   taxable at long-term capital gain tax rates.
    
 
   
   Any time you sell or exchange shares, it is considered a taxable event for
   you. Depending on the purchase price and the sale price of the shares you
   sell or exchange, you may have a gain or loss on the transaction. You are
   responsible for any federal income tax liabilities generated by your
   transaction.
    
 
   You will be notified in January each year about the federal tax status of
   distributions made by the Fund. Depending on your residence for tax purposes,
   distributions also may be subject to state and local taxes, including
   withholding taxes.
 
   
              TAX IDENTIFICATION NUMBER
    
 
              The Fund is required to withhold 31% of taxable dividends,
              capital gains distributions and redemptions proceeds paid
              to shareholders who have not provided the Fund with their
              Taxpayer Identification Number in compliance with IRS
              rules. To avoid this, make sure you provide your correct
              Tax Identification Number (Social Security Number for most
              investors) on your account application.
 
   Foreign shareholders may be subject to special withholding requirements.
   Consult your tax adviser about the federal, state and local tax consequences
   in your particular circumstances.
 
   OTHER SHAREHOLDER SERVICES
 
   As a shareholder of the Fund, you can take advantage of other service
   privileges which are described in the Owner's Manual:
 
   - Telephone Investment and Redemption Plan
   - Automatic Investment Plan
   - Systematic Withdrawal Plan
   - Retirement Plans

   MINIMUM INVESTMENTS
 
   You may purchase Funds
   through the Distributor
   or participating
   organizations, which
   may charge additional
   fees and may require
   higher or lower minimum
   investments or impose
   other limitations on
   buying and selling
   shares.
 
   
                            All purchases must be in U.S. dollars. A fee will be
                            charged for any checks that do not clear.
                            Third-party checks are not accepted. Your purchase
                            of shares will be effective on the same business day
                            if the Fund's Transfer Agent receives your order by
                            4:00 p.m. (12 noon for a money market fund), and
                            receives your form of payment by 4:00 p.m., eastern
                            time. Otherwise, your purchase will be effective on
                            the next business day. (See "Pricing of Fund
                            Shares.") Shares are held on account for you unless
                            you specify in writing that you would like to
                            receive a stock certificate (certificates are not
                            available for money market funds). We can only issue
                            a certificate for whole shares.
    
 
                            The Distributor may reject a purchase order if it
                            considers it in the best interest of the Fund and
                            its shareholders. A Fund may waive its minimum
                            purchase requirement.
   DIVIDENDS AND DISTRIBUTIONS
 
   All dividends and distributions will be automatically reinvested unless you
   request otherwise.

   SELLING SHARES
 
   As a mutual fund
   shareholder, you are
   technically selling shares
   when you request a
   withdrawal in cash. This
   is also known as redeeming
   shares.
                                   WITHDRAWING MONEY FROM YOUR INVESTMENT
 
                                   You may sell your shares at any time. Your
                                   sales price will be the next NAV after your
                                   sell order is received by the Fund, its
                                   transfer agent, or your investment
                                   representative. See section on "General
                                   Policies on Selling Shares" below.
 
                                   SYSTEMATIC WITHDRAWAL PLAN
 
                                   You can receive automatic payments from your
                                   account on a monthly, quarterly or annual
                                   basis. You can obtain details from the
                                   Distributor.
 
   INSTRUCTIONS FOR SELLING SHARES
 
   The Fund accepts telephone requests for redemptions of unissued shares.
 
   BY BANK WIRE OR CHECK VIA TELEPHONE
 
   
   1. Call 1-800-GABELLI (1-800-422-3554) with your account number, the amount
      of the redemption and instructions as to how you wish to receive your
      funds.
    
 
   
   2. If you are unable to reach the Fund by telephone, you may telecopy your
      redemption request to the Fund at 914-921-5118.
    
 
   NOTE: If you call by 4:00 p.m., eastern time, your payment will normally be
   wired to your bank on the following business day. (For Money Market Funds: If
   you call before 12:00 noon, eastern time, your payment will be wired to your
   bank on that day.) If you call after that time, your payment will be wired to
   your bank on the next business day. If you request your wire redemption by
   telephone, it must be at least $1,000. Your bank may charge a fee for
   incoming wires.
 
   BY BANK WIRE OR CHECK VIA MAIL
 
   Submit a redemption request to the Fund. Redemption requests may be made by
   letter to the Transfer Agent. You must specify the name of the Fund, the
   dollar amount or number of shares you wish to redeem and the account number.
   You must sign the letter in exactly the same way the account is registered,
   and if there is more than one owner of shares, all must sign. A signature
   guarantee is required for most requests.
 
   GENERAL POLICIES ON SELLING SHARES
 
   SIGNATURE GUARANTEES
 
   Signature guarantees are required on redemption requests for the following:
 
   
   - The check is not being mailed to the address on your account
    
   
   - The check is not being made payable to the owner of the account
    
   
   - The redemption proceeds are being transferred to another person's Fund
     account.
    
 
   A signature guarantee can be obtained from most banks and securities dealers.
   Notarized signatures are not considered a signature guarantee.

   SELLING SHARES
 
   VERIFYING TELEPHONE REDEMPTIONS
 
   The Fund makes every effort to ensure that telephone redemptions are only
   made by authorized shareholders. All telephone calls are recorded for your
   protection and you will be asked for information to verify your identity. If
   appropriate precautions have not been taken, the Fund may be liable for
   losses due to unauthorized transactions.
 
   REDEMPTIONS WITHIN 15 DAYS OF INVESTMENT
 
   When you have made an investment by check or through the automatic investment
   plan, your redemption proceeds will not be mailed until the Transfer Agent is
   satisfied that the check has cleared (which may require up to 15 days). You
   can avoid this delay by purchasing shares with a certified check or federal
   funds wire.
 
   REDEMPTION IN KIND
 
   The Fund reserves the right to make a redemption in kind - payment in
   portfolio securities rather than cash - for certain large redemption amounts
   that could hurt fund operations.
 
   REFUSAL OF REDEMPTION REQUEST
 
   Payment for shares may be delayed under extraordinary circumstances or as
   permitted by the Securities and Exchange Commission in order to protect
   remaining shareholders.
 
   CLOSING OF SMALL ACCOUNTS
 
   If your account (other than an IRA) falls below $500, the Fund may ask you to
   increase your balance. If it is still below $500 after 30 days, the Fund may
   close your account and send you the proceeds at the current NAV.
 
   UNDELIVERABLE DISTRIBUTION CHECKS
 
   If distribution checks (1) are returned and marked as "undeliverable" or (2)
   remain uncashed for six months, your account will be changed automatically so
   that all future distributions are reinvested in your account. Checks that
   remain uncashed for six months will be canceled and the money reinvested in
   the Fund at the then current net asset value.

   PRICING OF FUND SHARES
 
   HOW NAV IS CALCULATED
   The NAV is calculated by
   adding the total value of
   the Fund's investments and
   other assets, subtracting
   its liabilities and then
   dividing that figure by the
   number of outstanding
   shares of the Fund:
 
              NAV =
   Total Assets - Liabilities
 
  ----------------------------
        Number of Shares
           Outstanding
 
   You can find the Fund's NAV
   daily in the Wall Street
   Journal and other
   newspapers, or by calling
   1-800-GABELLI
   (800-422-3554).
   
                                          The net asset value, or NAV, of each
                                          Fund's Class AAA shares is determined
                                          and such shares are priced at the
                                          close of regular trading on the New
                                          York Stock Exchange, normally at 4:00
                                          p.m., eastern time, on days the New
                                          York Stock Exchange is open. Your
                                          order for purchase, sale or exchange
                                          of shares is priced at the next NAV
                                          calculated after your order is
                                          received by the Fund. This is what is
                                          known as the offering price.
    
 
                                          Fund securities are valued as of the
                                          close of trading on the primary
                                          exchange on which they trade. Fund
                                          securities are generally valued at
                                          current market prices. If market
                                          quotations are not available, prices
                                          will be based on the average of the
                                          latest bid and asked quotations for
                                          such securities prior to the valuation
                                          time, or the latest bid price if asked
                                          prices are not available. Debt
                                          securities with remaining maturities
                                          of 60 days or less will be valued at
                                          amortized cost, which the Board of
                                          Directors believes represents fair
                                          value.
 
                                          Some Fund securities may be listed on
                                          foreign exchanges that are open on
                                          days (such as U.S. holidays) when a
                                          Fund does not compute its NAV. This
                                          could cause the value of a Fund's
                                          portfolio investments to be affected
                                          on days when you cannot buy or sell
                                          shares.

    RISK/RETURN SUMMARY
 
    INVESTMENT OBJECTIVE              The Fund seeks to provide investors with long-term
                                      appreciation of capital. The production of any current
                                      income is incidental.
 
    PRINCIPAL INVESTMENT              The Fund invests primarily in equity securities of foreign
    STRATEGY                          issuers located in at least three countries outside the
                                      United States which are likely to have rapid growth in
                                      revenues and earnings and potential for above-average
                                      capital appreciation. Equity securities include common and
                                      preferred stocks, securities convertible into common stocks
                                      and securities like rights and warrants that have common
                                      stock characteristics. The Fund seeks companies that have
                                      the potential to grow faster than other companies in their
                                      respective equity markets and are priced at attractive
                                      valuation levels.
 
    PRINCIPAL                         The Fund's share prices will fluctuate with changes in the
    INVESTMENT RISKS                  market value of the Fund's securities. Stocks are subject to
                                      market, economic and business risks that cause their prices
                                      to fluctuate. Foreign securities are subject to currency,
                                      information and political risks. The Fund is also subject to
                                      the risk that the adviser's judgment about the above-average
                                      growth potential of particular stocks is incorrect. When you
                                      sell Fund shares, they may be worth less than what you paid
                                      for them. You can lose money by investing in the Fund.
    
   
    WHO MAY                           Consider investing in the Fund if you:

   RISK/RETURN SUMMARY AND FUND EXPENSES
 
- -
 
   
   The chart on this page shows the Fund's annual returns over the past three
   years and provides some indication of the risks of investing in the Fund by
   showing how its performance has varied from year to year. It does not reflect
   the impact of any applicable sales charges or account fees which would reduce
   returns. The Class A, B and C Shares are new classes of the Fund, for which
   performance is not yet available. The Class AAA shares of the Fund are
   offered in a separate prospectus. Although the shares are invested in the
   same portfolio of securities, the returns for Class A, B and C shares will
   differ from Class AAA returns shown in the bar chart because of differences
   in expenses and sales charges of each class. Sales charges are not reflected
   in the bar charts below. If reflected, the returns would be less than those
   shown. The table below compares the Fund's performance over time to that of
   the Lipper International Fund Average ("LIFA") and the Morgan Stanley EAFE
   Index ("MS EAFE"). The MS EAFE is a widely recognized, unmanaged index
   composed of common stocks from Europe, Australasia and the Far East. The LIFA
   represents an index of international equity mutual funds as tracked by
   Lipper, Inc. Of course, past performance does not indicate how the Fund will
   perform in the future. Both the chart and table assume reinvestment of
   dividends and distributions.

   RISK/RETURN SUMMARY AND FUND EXPENSES
 
   
   FUND EXPENSES
    
   FEES AND EXPENSES
   As an investor in the
   Fund, you will pay the
   following fees and
   expenses when you buy and
   hold shares. Annual Fund
   operating expenses are
   paid out of Fund assets,
   and are reflected in the
   share price.
 
   CONTINGENT DEFERRED SALES
   CHARGE
   Some Fund share classes
   impose a back end sales
   charge (load) if you sell
   your shares before a
   certain period of time has
   elapsed. This is called a
   Contingent Deferred Sales
   Charge (CDSC).

   
   EXPENSE EXAMPLE
    
   
   Use the example shown here to
   compare fees and expenses
   with those of other funds. It
   illustrates the amount of
   fees and expenses you would
   pay, assuming the following:
    
 
   - $10,000 investment
   - 5% annual return
   - redemption at the end of
     each period (except as
     noted)
   - no changes in the Funds' operating expenses
 
   Because this example is hypothetical and for comparison only, your actual
   costs may be higher or lower.

   INVESTMENT OBJECTIVES, STRATEGIES AND RISKS
 
 
   INVESTMENT OBJECTIVES AND PRINCIPAL STRATEGIES
 
   The Fund seeks long-term capital appreciation. To achieve its investment
   objective, the Fund invests primarily in the equity securities of foreign
   issuers. The Fund's investment objective may not be changed without
   shareholder approval. There is no assurance that the Fund will achieve its
   investment objective.
 
   
   Under normal circumstances, the Fund will invest at least 65% of its total
   assets in the equity securities of companies located in at least three
   countries outside the U.S. which the Adviser believes are likely to have
   rapid growth in revenues and earnings and potential for above-average capital
   appreciation.
    
 
   In choosing investments, the Adviser considers a number of factors,
   including:
 
   
   - a company's potential to grow faster than other companies in its respective
     equity market;
    
   
   - valuation levels;
    
   - the political stability and economic outlook of countries and regions; and
   - the prudent allocation among countries and regions to reduce volatility in
     the Fund's portfolio.
 
   The Fund intends to diversify its investments across different countries, but
   the percentage of Fund assets invested in particular countries or regions
   will change from time to time based on the Adviser's judgment. The Fund
   intends to invest in the securities of companies located in developed
   countries and, to a lesser extent, those located in emerging markets.
 
   
   As a defensive tactic in unusual market conditions, the Fund may temporarily
   invest up to 100% of its assets in money market instruments. This could
   potentially keep the Fund from achieving its goal.
    
 
   
   RISK FACTORS
    
 
   
   Investing in the Fund involves the following risks, listed in the order of
   importance. An investment in the Fund is not a bank deposit, is not insured
   or guaranteed by the Federal Deposit Insurance Corporation or any other
   government agency.
    
 
   MARKET RISK The market value of a security may move up and down, sometimes
   rapidly and unpredictably. These fluctuations, which are often referred to as
   "volatility", may cause a security to be worth less than it was worth at an
   earlier time. Market risk may affect a single issuer, industry, sector of the
   economy or the market as a whole. Market risk is common to most
   investments -- including stocks and bonds and the mutual funds that invest in
   them.
 
   FOREIGN SECURITIES RISK A fund that invests outside the U.S. carries
   additional risks that include:
 
     - CURRENCY RISK Fluctuations in exchange rates between the U.S. dollar and
       foreign currencies may negatively affect an investment. Adverse changes
       in exchange rates may erode or reverse any gains produced by
       foreign-currency denominated investments and may widen any losses. The
       Fund may, but is not required to, seek to reduce currency risk by hedging
       part or all of its exposure to various foreign currencies.

<PAGE>   28
 
   INVESTMENT OBJECTIVES, STRATEGIES AND RISKS
- -
 
   
     - INFORMATION RISK Key information about an issuer, security or market may
       be inaccurate or unavailable.
    
 
   
     - POLITICAL RISK Foreign governments may expropriate assets, impose capital
       or currency controls, impose punitive taxes or nationalize a company or
       industry. Any of these actions could have a severe effect on security
       prices and impair the Fund's ability to bring its capital or income back
       to the U.S. Other political risks include economic policy changes, social
       and political instability, military action and war.
    
 
   
     - ACCESS RISK The risk that some countries may restrict the Fund's access
       to investments or offer terms that are less advantageous than those for
       local investors. This could limit the attractive investment opportunities
       available to the Fund.
    
 
   
   FUND AND MANAGEMENT RISK The Fund invests in growth stocks and the Fund's
   price may decline if the market favors other types of stocks. If the Adviser
   is incorrect in its assessment of the growth prospects of the securities it
   holds, the value of the Fund's shares may decline.

   FUND MANAGEMENT
 
- -
 
   THE INVESTMENT ADVISER
 
   
   Gabelli Funds, LLC (the "Adviser"), One Corporate Center, Rye, NY 10580 is a
   limited liability company organized in 1999 after a reorganization of the
   predecessor, Gabelli Funds, Inc., which was formed in 1980. As of December
   31, 1998, Gabelli Funds, LLC and its affiliates manage more than $16.3
   billion in assets. Through its portfolio management team, Gabelli Funds, LLC
   makes the day-to-day investment decisions and continuously reviews,
   supervises and administers the Fund's investment programs.
    
 
   For these advisory services, the Adviser earns a fee of 1.00% of average net
   assets. Any portion of the total fees received by the Adviser may be used by
   the Adviser to provide shareholder and administrative services.
 
A
 
   THE PORTFOLIO MANAGER
 
   
   Mr. Caesar M.P. Bryan is primarily responsible for the day-to-day management
   of the Fund. Mr. Bryan has been a Senior Vice President and Portfolio Manager
   with GAMCO Investors, Inc., a wholly-owned subsidiary of Gabelli Asset
   Management Inc., the parent company of the Adviser, and Portfolio Manager of
   the Gabelli Gold Fund, Inc. since May 1994. Mr. Bryan served as Senior Vice
   President of Lexington Management Corporation from 1986 until May 1994.

   THE DISTRIBUTOR
 
   Gabelli & Company, Inc. is the Fund's distributor. Its address is One
   Corporate Center, Rye, NY 10580.
 
   The Statement of Additional Information has more detailed information about
   the Adviser and other service providers.
 
   
   YEAR 2000 As the year 2000 approaches, an issue has emerged regarding how the
   software used by the Fund's service providers can accommodate the date
   "2000." Failure to adequately address this issue could result in major
   systems or process failures which could disrupt the Fund's operations. The
   Adviser is in the process of working with the Fund's service providers to
   prepare for the year 2000. Based on information currently available, the
   Adviser does not expect that the Fund will incur significant operating
   expenses or be required to incur material costs to be year 2000 compliant.
   The Fund cannot guarantee, however, that all year 2000 issues will be
   identified and corrected by January 1, 2000, and any non-compliant computer
   system could hurt key Fund operations, such as shareholder servicing, pricing
   and trading. In addition, the Year 2000 problem may adversely affect the
   companies in which the Fund invests, particularly companies in foreign
   countries. For example, these companies may incur substantial costs to
   correct the problem. To the extent that the impact on a Fund holding is
   negative, it could seriously affect the Fund's performance.

   SHAREHOLDER INFORMATION
 
   PRICING OF FUND SHARES
 
   HOW NAV IS CALCULATED
 
   The NAV is calculated by
   adding the total value of
   the Fund's investments and
   other assets, subtracting
   its liabilities and then
   dividing that figure by the
   number of outstanding
   shares of the Fund:
 
              NAV =
   Total Assets - Liabilities

        Number of Shares
           Outstanding

   daily in the Wall Street
   Journal and other
   newspapers or by calling
   1-800-GABELLI
   (800-422-3554).
                                          The Fund's net asset value, or NAV, is
                                          determined and its shares are priced
                                          at the close of regular trading of the
                                          New York Stock Exchange, normally at

                                          Fund securities are valued as of the
                                          close of trading on the primary
                                          exchange on which they trade. The
                                          Fund's securities are generally valued
                                          at current market prices. If market
                                          quotations are not available, prices
                                          will be based on the average of the
                                          latest bid and asked quotations for
                                          such securities prior to the valuation

                                          amortized cost, which the Board of
                                          Directors believes represents fair
                                          value.
 
                                          Fund securities may be listed on

                                          days (such as U.S. holidays) when the
                                          Fund does not compute its NAV. This
                                          could cause the value of the Fund's
                                          portfolio investments to be affected
                                          on days when you cannot buy or sell
                                          shares.

    CALCULATION OF SALES CHARGES
    CLASS A SHARES
 
   Class A shares are sold at their public offering price. This price
   includes the initial sales charge. Therefore, part of the money you invest
   will be used to pay the sales charge. The remainder is invested in Fund
   shares. The sales charge decreases with larger purchases. There is no
   sales charge on reinvested dividends and distributions and on purchases
   greater than $1 million.

    CLASS B AND CLASS C SHARES
 
   Class B and Class C shares are offered at NAV, without any up-front sales
   charge. Therefore, all the money you invest is used to purchase Fund
   shares. However, if you sell your Class B shares of the Fund before the
   sixth anniversary, you will have to pay a contingent deferred sales charge
   at the time of redemption. If you sell your Class C shares before the
   second anniversary of purchase, you will pay a 1% CDSC at the time of
   redemption. The CDSC will be based upon the lower of the NAV at the time
   of purchase or the NAV at the time of redemption according to the schedule
   below. There is no CDSC on reinvested dividends or distributions.

   If you sell some but not all of your Class B or C shares, certain shares
   not subject to the CDSC (i.e., shares purchased with reinvested dividends)
   will be redeemed first, followed by shares subject to the lowest CDSC
   (typically shares held for the longest time).
 
   (1) The Distributor reserves the right to pay the entire sales charge to
       dealers. If that occurs the dealer may be considered an "underwriter"
       under federal securities laws.
   
   (2) There is no initial sales charge on purchases of $2 million or more.
       However, a contingent deferred sales charge (CDSC) of up to 1.00% of
       the purchase price will be charged to the shareholder if shares are
       redeemed in the first year after purchase. This charge will be based
       on the lower of your cost for the shares or their NAV at the time of
       redemption. There will be no CDSC on reinvested dividends and
       distributions.

   CONVERSION FEATURE -- CLASS B SHARES
 
   - Class B shares automatically convert to Class A shares of the Fund on the
     first business day of the eighty-fifth calendar month following the
     calendar month in which such shares were issued.
   - After conversion, your shares will be subject to the lower distribution
     fees charged on Class A shares, which will increase your investment return
     compared to the Class B shares.
   - You will not pay any sales charge or fees when your shares convert, nor
     will the transaction be subject to any tax.
   - If you purchased Class B shares of one Fund which you exchanged for Class B
     shares of another Fund, your holding period will be calculated from the
     time of your original purchase of Class B shares. The dollar value of Class
     A shares you receive will equal the dollar value of the B shares converted.
   - If you exchange shares into a Gabelli money market fund, your holding
     period will be suspended.
   - The automatic conversion of Class B shares to Class A shares may be
     suspended by the Board of Directors at any time it determines such
     suspension to be required under applicable law or in the exercise of their
     fiduciary duties; provided, however, that if the Board determines that the
     suspension is likely to continue for a substantial period of time, the
     Board of Directors will seek to create an additional class or additional
     classes of shares into which Class B shares are eligible for conversion
     under the rules of the Securities and Exchange Commission and other
     applicable law.
 
   
   SALES CHARGE REDUCTIONS
 
   Reduced sales charges for Class A shares are available to shareholders with
   investments of $50,000 or more. In addition, you may qualify for reduced
   sales charges under the following circumstances:
 
   - Letter of Intent. You inform the Fund in writing that you intend to
     purchase enough shares over a 13-month period to qualify for a reduced
     sales charge. You must include a minimum of 5% of the total amount you
     intend to purchase with your letter of intent.
 
   - Rights of Accumulation. When the value of shares you already own plus the
     amount you intend to invest reaches the amount needed to qualify for
     reduced sales charges, your added investment will qualify for the reduced
     sales charge.
 
   - Combination Privilege. Combine accounts of multiple Funds or accounts of
     immediate family household members (spouse and children under 21) to
     achieve reduced sales charges.
 
   SALES CHARGE WAIVERS
 
   CLASS A SHARES
 
   The following qualify for waivers of sales charges:
 
   - Reinvestment of distributions from a deferred compensation plan, agency,
     trust, or custody account that was maintained by the Adviser, its
     affiliates or any NASD member.
 
   - Shares purchased by directors, officers, employees of the Fund, the Adviser
     or the Distributor and their affiliates, and members of the immediate
     family. The term "immediate family" refers to spouses, children and
     grandchildren (adopted or natural), parents, grandparents, siblings, a
     spouse's siblings, a sibling's spouse and a sibling's children.

              REINSTATEMENT PRIVILEGE

              If you have sold Class A shares and decide to reinvest in
              the Fund within a 30 day period, you will not be charged
              the applicable sales load on amounts up to the value of the
              shares you sold. You must provide a written reinstatement
              request and payment within 30 days of the date your
              instructions to sell were processed.

   CLASS B SHARES

   The CDSC will be waived under certain circumstances, including the following:

   - Distributions from retirement plans if the distributions are made following
     the death or disability of shareholders or plan participants.

   - Redemptions from accounts other than retirement accounts following the
     death or disability of the shareholder.

   - Minimum required distributions made from an IRA or other retirement plan
     account after the shareholder reaches age 59 1/2.

   - Distributions from tax-deferred retirement plans after the shareholder's
     retirement.

   - Returns of excess contributions to retirement plans following the death or
     disability of the shareholder.

   - Distributions of less than 5% of the annual account value under a
     Systematic Withdrawal Plan.

   - Shares issued in a plan of reorganization sponsored by the Adviser, or
     shares redeemed involuntarily in a similar situation.
    
 
   DISTRIBUTION (12B-1) FEES
 
   The Fund has adopted a distribution plan pursuant to Rule 12b-1 under the
   1940 Act which authorizes payments by the Fund to compensate the Distributor
   and other dealers and investment representatives for services and expenses
   relating to the sale and distribution of the Fund's shares. Rule 12b-1 fees
   are paid from Fund assets on an ongoing basis, and increase the cost of your
   investment.
 
   - The 12b-1 fees vary by share class as follows:
     - Class A shares pay a 12b-1 fee of .25% of the average daily net assets of
       the Fund.
     - Class B and Class C shares pay a 12b-1 fee of 1.00% of the average daily
       net assets of the Fund. This will cause annual expenses for Class B and
       Class C shares to be higher and dividends to be lower than for Class A
       shares.
   - The higher 12b-1 fee on Class B and Class C shares, together with the CDSC,
     allow the Distributor to sell Class B and Class C shares without an
     "up-front" sales charge. In particular, these fees help to defray the
     Distributor's costs of advancing brokerage commissions to investment
     representatives.
   - The Distributor may use up to .25% of the 12b-1 fee for shareholder
     servicing and up to .75% for distribution.
 
   Long-term shareholders may pay indirectly more than the equivalent of the
   maximum permitted front-end sales charge due to the recurring nature of 12b-1
   distribution fees.

   DIVIDENDS, DISTRIBUTIONS AND TAXES
    
 
   Any income the Fund receives in the form of interest or dividends is paid
   out, less expenses, to its shareholders. The Fund declares and pays dividends
   from net investment income and capital gains, if any, on an annual basis.
 
   Dividends and distributions are treated in the same manner for federal income
   tax purposes whether you receive them in cash or in additional shares.
 
   
   The Fund expects that its dividends will primarily consist of net investment
   income and, if any, short-term and long-term capital gains. Fund
   distributions are taxed based on the length of time the Fund holds its
   assets, regardless of how long you have held Fund shares. Distributions from
   net investment income and short-term capital gains are taxable as ordinary
   income. Such distributions are taken into account for tax purposes in the
   year in which they are declared, even if they appear on your account
   statement the following year. Long-term capital gain distributions are
   taxable at long-term capital gain tax rates.
    
 
   
   Any time you sell or exchange shares, it is considered a taxable event for
   you. Depending on the purchase price and the sale price of the shares you
   sell or exchange, you may have a gain or loss on the transaction. You are
   responsible for any federal income tax liabilities generated by your
   transaction.
    
 
   
   You will be notified in January each year about the federal tax status of
   distributions made by the Fund. Depending on your residence for tax purposes,
   distributions also may be subject to state and local taxes, including
   withholding taxes.
    
 
              TAX IDENTIFICATION NUMBER
 
              The Fund is required to withhold 31% of taxable dividends,
              capital gains distributions and redemptions proceeds paid
              to shareholders who have not provided the Fund with their
              Taxpayer Identification Number in compliance with IRS
              rules. To avoid this, make sure you provide your correct
              Tax Identification Number (Social Security Number for most
              investors) on your account application.
 
   Foreign shareholders may be subject to special withholding requirements.
   Consult your tax adviser about the federal, state and local tax consequences
A  in your particular circumstances.

   MINIMUM INVESTMENTS
 
   You may purchase Funds
   through the Distributor
   or participating
   organizations, which
   may charge additional
   fees and may require
   higher or lower minimum
   investments or impose
   other limitations on
   buying and selling
   shares.
 
   
                            All purchases must be in U.S. dollars. A fee will be
                            charged for any checks that do not clear.
                            Third-party checks are not accepted. Your purchase
                            of shares will be effective on the same business day
                            if the Fund's Transfer Agent receives your order by
                            4:00 p.m. (12 noon for a money market fund), and
                            receives your form of payment by 4:00 p.m., eastern
                            time. Otherwise, your purchase will be effective on
                            the next business day. (See "Pricing of Fund
                            Shares.") Shares are held on account for you unless
                            you specify in writing that you would like to
                            receive a stock certificate (certificates are not
                            available for money market funds). We can only issue
                            a certificate for whole shares.
    
 
   
                            The Distributor may reject a purchase order if it
                            considers it in the best interest of the Fund and
                            its shareholders. A Fund may waive its minimum
                            purchase requirement.
    
   DIVIDENDS AND DISTRIBUTIONS
 
   All dividends and distributions will be automatically reinvested unless you
   request otherwise.

   SELLING SHARES
 
   
   If selling your shares through your financial adviser or broker, ask him or
   her for redemption procedures. Your adviser and/or broker may have
   transaction minimums and/or transaction times which will affect your
   redemption. For all other sales transactions, follow the instructions below.

   As a mutual fund
   shareholder, you are
   technically selling shares
   when you request a
   withdrawal in cash. This
   is also known as redeeming
   shares.

   INSTRUCTIONS FOR SELLING SHARES

   BY BANK WIRE OR CHECK VIA TELEPHONE
 
   
   1. Call 1-800-GABELLI (1-800-422-3554) with your account number, the amount
      of the redemption and instructions as to how you wish to receive your
      funds.

   2. If you are unable to reach the Fund by telephone, you may telecopy your
      redemption request to the Fund at 914-921-5118.
    
 
   NOTE: If you call by 4:00 p.m., eastern time, your payment will normally be
   wired to your bank on the following business day. (For Money Market Funds: If
   you call before 12:00 noon, eastern time, your payment will be wired to your
   bank on that day). If you call after that time, your payment will be wired to
   your bank on the next business day. If you request your wire redemption by
   telephone, it must be at least $1,000. Your bank may charge a fee for
   incoming wires.
 
   BY BANK WIRE OR CHECK VIA MAIL
 
   Submit a redemption request to the Fund. Redemption requests may be made by
   letter to the Transfer Agent. You must specify the name of the Fund, the
   dollar amount or number of shares you wish to redeem and the account number.
   You must sign the letter in exactly the same way the account is registered,
   and if there is more than one owner of shares, all must sign. A signature
   guarantee is required for most requests.

                                                                               5

   SELLING SHARES
 
   GENERAL POLICIES ON SELLING SHARES
 
   SIGNATURE GUARANTEES
 
   Signature guarantees are required on redemption requests for the following:
   
   - The check is not being mailed to the address on your account

   - The check is not being made payable to the owner of the account

   - The redemption proceeds are being transferred to another person's Fund
     account.
    
 
   A signature guarantee can be obtained from most banks and securities dealers.
   Notarized signatures are not considered a signature guarantee.
 
   VERIFYING TELEPHONE REDEMPTIONS
 
   The Fund makes every effort to ensure that telephone redemptions are only
   made by authorized shareholders. All telephone calls are recorded for your
   protection and you will be asked for information to verify your identity. If
   appropriate precautions have not been taken, the Fund may be liable for
   losses due to unauthorized transactions.
 
   REDEMPTIONS WITHIN 15 DAYS OF INVESTMENT
 
   When you have made an investment by check or through the automatic investment
   plan, your redemption proceeds will not be mailed until the Transfer Agent is
   satisfied that the check has cleared (which may require up to 15 days). You
   can avoid this delay by purchasing shares with a certified check or federal
   funds wire.
 
   REDEMPTION IN KIND
 
   The Fund reserves the right to make a redemption in kind - payment in
   portfolio securities rather than cash - for certain large redemption amounts
   that could hurt fund operations.
 
   REFUSAL OF REDEMPTION REQUEST
 
   Payment for shares may be delayed under extraordinary circumstances or as
   permitted by the Securities and Exchange Commission in order to protect
   remaining shareholders.
 
   CLOSING OF SMALL ACCOUNTS
 
   If your account (other than IRA) falls below $500, the Fund may ask you to
   increase your balance. If it is still below $500 after 30 days, the Fund may
   close your account and send you the proceeds at the current NAV.
 
   UNDELIVERABLE DISTRIBUTION CHECKS
 
   If distribution checks (1) are returned and marked as "undeliverable" or (2)
   remain uncashed for six months, your account will be changed automatically so
   that all future distributions are reinvested in your account. Checks that
   remain uncashed for six months will be canceled and the money reinvested in
   the Fund at the then current net asset value.
                                                       QUESTIONS?

   PRICING OF FUND SHARES
 
   
   HOW NAV IS CALCULATED
    
   The NAV is calculated by
   adding the total value of
   the Fund's investments and
   other assets, subtracting
   its liabilities and then
   dividing that figure by the
   number of outstanding
   shares of the Fund:
 
   
              NAV =
   Total Assets - Liabilities
   --------------------------
        Number of Shares
           Outstanding
    

   ---------------------------
 
   You can find the Fund's NAV
   daily in the Wall Street
   Journal and other
   newspapers, or by calling
   1-800-GABELLI
   (800-422-3554).
                                          The Fund's net asset value, or NAV, is
                                          determined and its shares are priced
                                          at the close of regular trading on the
                                          New York Stock Exchange, normally at
                                          4:00 p.m., eastern time, on days the
                                          New York Stock Exchange is open. Your
                                          order for purchase, sale or exchange
                                          of shares is priced at the next NAV
                                          calculated after your order is
                                          received by the Fund less any
                                          applicable sales charge as noted in
                                          the section on "Distribution
                                          Arrangements/Sales Charges." This is
                                          what is known as the offering price.
 
                                          Fund securities are valued as of the
                                          close of trading on the primary
                                          exchange on which they trade. Fund
                                          securities are generally valued at
                                          current market prices. If market
                                          quotations are not available, prices
                                          will be based on the average of the
                                          latest bid and asked quotations for
                                          such securities prior to the valuation
                                          time, or the latest bid price if asked
                                          prices are not available. Debt
                                          securities with remaining maturities
                                          of 60 days or less will be valued at
                                          amortized cost, which the Board of
                                          Directors believes represents fair
                                          value.
 
                                          Some Fund securities may be listed on
                                          foreign exchanges that are open on
                                          days (such as U.S. holidays) when a
                                          Fund does not compute its NAV. This
                                          could cause the value of a Fund's
                                          portfolio investments to be affected
                                          on days when you cannot buy or sell
                                          shares.

    CALCULATION OF SALES CHARGES
 
    CLASS A SHARES
 
   Class A shares are sold at their public offering price. This price includes
   the initial sales charge. Therefore, part of the money you invest will be
   used to pay the sales charge. The remainder is invested in Fund shares. The
   sales charge decreases with larger purchases. There is no sales charge on
   reinvested dividends and distributions and on purchases greater than $1
   million.
 
 
                                                                               9

    CLASS B AND CLASS C SHARES
 
   Class B and Class C shares are offered at NAV, without any up-front sales
   charge. Therefore, all the money you invest is used to purchase Fund
   shares. However, if you sell your Class B shares of the Fund before the
   seventh anniversary of purchase, you will have to pay a contingent
   deferred sales charge at the time of redemption. If you sell your Class C
   shares before the second anniversary of purchase, you will pay a 1% CDSC
   at the time of redemption. The CDSC will be based upon the lower of the
   NAV at the time of purchase or the NAV at the time of redemption according
   to the schedule below. There is no CDSC on reinvested dividends or
   distributions.

   If you sell some but not all of your Class B or Class C shares, certain
   shares not subject to the CDSC (i.e., shares purchased with reinvested
   dividends) will be redeemed first, followed by shares subject to the
   lowest CDSC (typically shares held for the longest time).
    
 
   (1) The Distributor reserves the right to pay the entire sales charge to
       dealers. If that occurs the dealer may be considered an "underwriter"
       under federal securities laws.
 
   (2) There is no initial sales charge on purchases of $1 million or more.
       However, a contingent deferred sales charge (CDSC) of up to 1.00% of
       the purchase price will be charged to the shareholder if shares are
       redeemed in the first year after purchase. This charge will be based
       on the lower of your cost for the shares or their NAV at the time of
       redemption. There will be no CDSC on reinvested dividends and
       distributions.

   DISTRIBUTION ARRANGEMENTS/SALES CHARGES
 
   CONVERSION FEATURE -- CLASS B SHARES
 
   
   - Class B shares automatically convert to Class A shares of the same Fund on
     the first business day of the eighty-fifth calendar month following the
     calendar month in which the shares were purchased.

   - After conversion, your shares will be subject to the lower distribution
     fees charged on Class A shares, which will increase your investment return
     compared to the Class B shares.

   - You will not pay any sales charge or fees when your shares convert, nor
     will the transaction be subject to any tax.

   - If you purchased Class B shares of one Fund which you exchanged for Class B
     shares of another Fund, your holding period will be calculated from the
     time of your original purchase of Class B shares. The dollar value of Class
     A shares you receive will equal the dollar value of the Class B shares
     converted.

   - If you exchange shares into a Gabelli money market fund, your holding
     period will be suspended.

   - The automatic conversion of Class B shares to Class A shares may be
     suspended by the Board of Directors at any time it determines such
     suspension to be required under applicable law or in the exercise of their
     fiduciary duties; provided, however, that if the Board determines that the
     suspension is likely to continue for a substantial period of time, the
     Board of Directors will seek to create an additional class or additional
     classes of shares into which Class B shares are eligible for conversion
     under the rules of the Securities and Exchange Commission and other
     applicable law.
    
 
 
   SALES CHARGE REDUCTIONS
 
   Reduced sales charges for Class A shares are available to shareholders with
   investments of $50,000 or more. In addition, you may qualify for reduced
   sales charges under the following circumstances:
 
   
   - Letter of Intent. You inform the Fund in writing that you intend to
     purchase enough shares over a 13-month period to qualify for a reduced
     sales charge. You must include a minimum of 5% of the total amount you
     intend to purchase with your letter of intent.

   - Rights of Accumulation. When the value of shares you already own plus the
     amount you intend to invest reaches the amount needed to qualify for
     reduced sales charges, your added investment will qualify for the reduced
     sales charge.

   - Combination Privilege. Combine accounts of multiple Funds or accounts of
     immediate family household members (spouse and children under 21) to
     achieve reduced sales charges.
    

 
                                                                              11

   DISTRIBUTION ARRANGEMENTS/SALES CHARGES
 
   SALES CHARGE WAIVERS
 
   CLASS A SHARES
 
   The following qualify for waivers of sales charges:
 
   
   - Reinvestment of distributions from a deferred compensation plan, agency,
     trust, or custody account that was maintained by the Adviser, its
     affiliates or any NASD member.

   - Shares purchased by directors, officers, employees of the Fund, the Adviser
     or the Distributor and their affiliates, and members of the immediate
     family. The term "immediate family" refers to spouses, children and
     grandchildren (adopted or natural), parents, grandparents, siblings, a
     spouse's siblings, a sibling's spouse and a sibling's children.
    

              -----------------------------------------------------------
              REINSTATEMENT PRIVILEGE
 
              If you have sold Class A shares and decide to reinvest in
              the Fund within a 30 day period, you will not be charged
              the applicable sales load on amounts up to the value of the
              shares you sold. You must provide a written reinstatement
              request and payment within 30 days of the date your
              instructions to sell were processed.
              -----------------------------------------------------------  

   CLASS B SHARES
 
   The CDSC will be waived under certain circumstances, including the following:
 
   
   - Distributions from retirement plans if the distributions are made following
     the death or disability of shareholders or plan participants.

   - Redemptions from accounts other than retirement accounts following the
     death or disability of the shareholder.

   - Minimum required distributions made from an IRA or other retirement plan
     account after the shareholder reaches age 59 1/2.

   - Distributions from tax-deferred retirement plans after the shareholder's
     retirement.

   - Returns of excess contributions to retirement plans following the death or
     disability of the shareholder.

   - Distributions of less than 5% of the annual account value under a
     Systematic Withdrawal Plan.

   - Shares issued in a plan of reorganization sponsored by the Adviser, or
     shares redeemed involuntarily in a similar situation.

          THE FOLLOWING INFORMATION SUPPLEMENTS THAT IN THE PROSPECTUS.


                                   INVESTMENTS

Subject to the Fund's policy of investing at least 65% of its total assets in
the securities of foreign companies, the Fund may invest in any of the
securities described below.

EQUITY SECURITIES

Because the Fund in seeking to achieve its investment objective may invest in
the common stocks of both foreign and domestic issuers, an investment in the
Fund should be made with an understanding of the risks inherent in any
investment in common stocks including the risk that the financial condition of
the issuers of the Fund's portfolio securities may become impaired or that the
general condition of the stock market may worsen (both of which may contribute
directly to a decrease in the value of the securities and thus in the value of
the Fund's shares). Additional risks include risks associated with the right to
receive payments from the issuer which is generally inferior to the rights of
creditors of, or holders of debt obligations or preferred stock issued by, the
issuer. The Fund also does not expect to invest in excess of 5% of its assets in
securities of unseasoned issuers (companies that have operated less than three
years), which, due to their short operating history, may have less information
available and may not be as liquid as other securities.

Moreover, common stocks do not represents an obligation of the issuer and
therefore do not offer any assurance of income or provide the degree of
protection of debt securities. The issuance of debt securities or even preferred
stock by an issuer will create prior claims for payment of principal, interest
and dividends which could adversely affect the ability and inclination of the
issuer to declare or pay dividends on its common stock or the economic interest
of holders of common stock with respect to assets of the issuer upon liquidation
or bankruptcy. Further, unlike the debt securities which typically have a stated
principal amount payable at maturity (which value will be subject to market
fluctuations prior thereto), common stocks have neither a fixed principal amount
nor a maturity and have values which are subject to market fluctuations for as
long as the common stocks remain outstanding. Common stocks are especially
susceptible to general stock market movements and to volatile increases and
decreases in value as market confidence in and perceptions of the issuer's
change. These perceptions are based on unpredictable factors including
expectations regarding government, economic, monetary and fiscal policies,
inflation and interest rates, economic expansion or contraction, and global or
regional political, economic or banking crises. The value of the common stocks
in the Fund's portfolio thus may be expected to fluctuate.

Preferred stocks are usually entitled to rights on liquidation which are senior
to those of common stocks. For these reasons, preferred stocks generally entail
less risk than common stocks. Such securities may pay cumulative dividends.
Because the dividend rate is pre-established, and they are senior to common
stocks, such securities tend to have less possibility of capital appreciation.

Some of the securities in the Fund may be in the form of depository receipts.
Depository receipts usually represent common stock or other equity securities of
non-U.S. issuers deposited with a custodian in a depository. The underlying
securities are usually withdrawable at any time by surrendering the depository
receipt. Depository receipts are usually denominated in U.S. dollars and
dividends and other payments from the issuer are converted by the custodian into
U.S. dollars before payment to receipt holders. In other respects depository
receipts for foreign securities have the same characteristics as the underlying
securities. Depository receipts that are not sponsored by the issuer may be less
liquid and there may be less readily available public information about the
issuer.

SOVEREIGN DEBT SECURITIES

The Fund may invest in securities issued or guaranteed by any country and
denominated in any currency. The Fund expects to invest in the securities of
companies located in developed countries, and to a lesser extent, those located
in emerging markets. Developed markets include Australia, Austria, Belgium,

                                      B-2
<PAGE>   52

Canada, Denmark, Finland, France, Germany, Ireland, Italy, Japan, Luxembourg,
the Netherlands, New Zealand, Norway, Spain, Sweden, Switzerland, the United
Kingdom and the United States. An emerging country is any country which is
generally considered to be an emerging or developing country by the
International Bank for Reconstruction and Development (more commonly referred to
as the World Bank) and the International Finance Corporation, as well as
countries that are classified by the United Nations or otherwise regarded by its
authorities as emerging or developing, at the time of the Fund's investment. The
obligations of governmental entities have various kinds of government support
and include obligations issued or guaranteed by governmental entities with
taxing power. These obligations may or may not be supported by the full faith
and credit of a government. Debt securities issued or guaranteed by foreign
governmental entities have credit characteristics similar to those of domestic
debt securities but include additional risks. These additional risks include
those resulting from devaluation of currencies, future adverse political and
economic developments and other foreign governmental laws. The Fund may have
limited legal recourse in the event of default. Also, the Fund may have
difficulty disposing of certain sovereign debt obligations because there may be
a limited trading market for such securities.

The Fund may also purchase securities issued by quasi-governmental or
supranational agencies such as the Asian Development Bank, the International
Bank for Reconstruction and Development, the Export-Import Bank and the European
Investment Bank. The governmental members, or "stockholders," usually make
initial capital contributions to the supranational entity and in many cases are
committed to make additional capital contributions if the supranational entity
is unable to repay its borrowings. The Fund will not invest more than 25% of its
assets in the securities of such supranational entities.

The Fund may invest in securities denominated in a multi-national currency unit.
An illustration of a multi-national currency unit is the European Monetary Unit
(the "EUR"), which is a combination of the economic structures of the member
nations of the European Monetary Union into to a single currency. This union
includes France, Germany, the Netherlands, and other countries. The specific
legacy currencies rates comprising the ECU were fixed on December 31, 1998 to
reflect the relative values of the underlying currencies to the newly created
EUR. Such investments involve credit risks associated with the issuer and
currency risks associated with the currency in which the obligation is
denominated.

NONCONVERTIBLE FIXED INCOME SECURITIES

The category of fixed income securities which are not convertible or
exchangeable for common stock includes preferred stocks, bonds, debentures,
notes and money market instruments such as commercial paper and bankers
acceptances. There is no minimum credit rating for these securities in which the
Fund may invest. Accordingly, the Fund could invest in securities in default,
although the Fund will not invest more than 5% of its assets in such securities.

Up to 25% of the Fund's total assets may be invested in lower-quality debt
securities although the Fund currently does not expect to invest more than 5% of
its assets in such securities. The market values of lower-quality fixed income
securities tend to be less sensitive to changes in prevailing interest rates
than higher-quality securities but more sensitive to individual corporate
developments than higher-quality securities. Such lower-quality securities also
tend to be more sensitive to economic conditions than are higher-quality
securities. Accordingly, these lower-quality securities are considered
predominantly speculative with respect to the issuer's capacity to pay interest
and repay principal in accordance with the terms of the obligation and will
generally involve more credit risk than securities in the higher-quality
categories. Even securities rated Baa or BBB by Moody's Investors Service, Inc.
("Moody's") and Standard and Poor's Ratings Services ("S&P"), respectively,
which ratings are considered investment grade, possess some speculative
characteristics, and changes in economic conditions or other circumstances are
more likely to lead to a weakened capacity to make principal and interest
payments than is the case with higher-grade bonds. See "Appendix -- Description
of Ratings." There are risks involved in applying credit ratings as a method of
evaluating high yield obligations in that credit ratings evaluate the safety of
principal and interest payments, not market value risk. In addition, credit
rating agencies may not change credit ratings on a timely basis to reflect
changes in economic or company conditions that affect a 

                                      B-3

<PAGE>   53


   
security's market value. The Fund will rely on the judgment, analysis and
experience of its adviser, Gabelli Funds, LLC (the "Adviser"), in evaluating the
creditworthiness of an issuer. In this evaluation, the Adviser will take into
consideration, among other things, the issuer's financial resources and ability
to cover its interest and fixed charges, factors relating to the issuer's
industry and its sensitivity to economic conditions and trends, its operating
history, the quality of the issuer's management and regulatory matters.
    

The risk of loss due to default by the issuer is significantly greater for the
holders of lower quality securities because such securities are generally
unsecured and are often subordinated to other obligations of the issuer. During
an economic downturn or a sustained period of rising interest rates, highly
leveraged issuers of lower quality securities may experience financial stress
and may not have sufficient revenues to meet their interest payment obligations.
An issuer's ability to service its debt obligations may also be adversely
affected by specific corporate developments, its inability to meet specific
projected business forecasts, or the unavailability of additional financing.

Factors adversely affecting the market value of high yield and other fixed
income securities will adversely affect the Fund's net asset value. In addition,
the Fund may incur additional expenses to the extent that it is required to seek
recovery upon a default in the payment of principal of or interest on its
portfolio holdings. At times, adverse publicity regarding lower-quality
securities has depressed prices for such securities to some extent.

From time to time, proposals have been discussed regarding new legislation
designed to limit the use of certain high yield debt securities by issuers in
connection with leveraged buy-outs, mergers and acquisitions, or to limit the
deductibility of interest payments on such securities. Such proposals, if
enacted into law, could reduce the market for such debt securities generally,
could negatively affect the financial condition of issuers of high yield
securities by removing or reducing a source of future financing, and could
negatively affect the value of specific high yield issues and the high yield
market in general. For example, under a provision of the Internal Revenue Code
enacted in 1989, a corporate issuer may be limited from deducting all of the
original issue discount on high-yield discount obligations (i.e., certain types
of debt securities issued at a significant discount to their face amount).
The likelihood of passage of any additional legislation or the effect thereof is
uncertain.

The secondary trading market for lower-quality fixed income securities is
generally not as liquid as the secondary market for higher-quality securities
and is very thin for some securities. The relative lack of an active secondary
market may have an adverse impact on market price and the Fund's ability to
dispose of particular issues when necessary to meet liquidity needs or in
response to a specific economic event such as a deterioration in the
creditworthiness of the issuer. The relative lack of an active secondary market
for certain securities may also make it more difficult for the Fund to obtain
accurate market quotations for purposes of valuing its portfolio. Market
quotations are generally available on many high yield issues only from a limited
number of dealers and may not necessarily represent firm bids of such dealers or
prices for actual sales. During such times, the responsibility of the Board of
Directors to value the securities becomes more difficult and judgment plays a
greater role in valuation because there is less reliable, objective data
available.

CONVERTIBLE SECURITIES

The Fund may invest up to 25% of its total assets in convertible securities
rated, at the time of investment, less than BBB by S&P or Baa by Moody's or
unrated but of equivalent credit quality in the judgment of the Adviser,
although the Fund currently does not expect to invest in excess of 5% of its
assets in such securities.

Some of the convertible securities in the Fund's portfolio may be "Pay-in-Kind"
securities. During a designated period from original issuance, the issuer or
such a security may pay dividends or interest to the holder by issuing
additional fully paid and nonassessable shares or units of the same or another
specified security. While no securities investment is completely without risk,
investments in convertible securities 

                                      B-4
<PAGE>   54

generally entail less risk than common stock, although the extent to which such
risk is reduced depends in large measure upon the degree to which the
convertible security sells above its value as a fixed-income security.

SECURITIES SUBJECT TO REORGANIZATION

The Fund may invest in securities for which a tender or exchange offer has been
made or announced and in securities of companies for which a merger,
consolidation, liquidation or reorganization proposal has been announced if, in
the judgment of the Adviser, there is a reasonable prospect of capital
appreciation significantly greater than the brokerage and other transaction
expenses involved.

In general, securities which are the subject of such an offer or proposal sell
at a premium to their historic market price immediately prior to the
announcement of the offer or may also discount what the stated or appraised
value of the security would be if the contemplated transaction were approved or
consummated. Such investments may be advantageous when the discount
significantly overstates the risk of the contingencies involved; significantly
undervalues the securities, assets or cash to be received by shareholders of the
prospective portfolio company as a result of the contemplated transaction; or
fails adequately to recognize the possibility that the offer or proposal may be
replaced or superseded by an offer or proposal of greater value. The evaluation
of such contingencies requires unusually broad knowledge and experience on the
part of the Adviser, which must appraise not only the value of the issuer and
its component businesses as well as the assets or securities to be received as a
result of the contemplated transaction but also the financial resources and
business motivation of the offeror and the dynamics and business climate when
the offer or proposal is in process. Since such investments are ordinarily
short-term in nature, they will tend to increase the turnover ratio of the Fund,
thereby increasing its brokerage and other transaction expenses. The Adviser
intends to select investments of the type described which, in its view, have a
reasonable prospect of capital appreciation which is significant in relation to
both risk involved and the potential of available alternate investments.

OPTIONS

The Fund may purchase or sell options on individual securities as well as on
indices of securities as a means of achieving additional return or of hedging
the value of its portfolio.

A call option is a contract that gives the holder of the option the right, in
return for a premium paid, to buy from the seller the security underlying the
option at a specified exercise price at any time during the term of the option
or, in some cases, only at the end of the term of the option. The seller of the
call option has the obligation upon exercise of the option to deliver the
underlying security upon payment of the exercise price. A put option is a
contract that gives the holder of the option the right in return for a premium
to sell to the seller the underlying security at a specified price. The seller
of the put option, on the other hand, has the obligation to buy the underlying
security upon exercise at the exercise price. The Fund's transactions in options
may be subject to specific segregation requirements. See "Hedging Transactions"
below.

If the Fund has sold an option, it may terminate its obligation by effecting a
closing purchase transaction. This is accomplished by purchasing an option of
the same series as the option previously sold. There can be no assurance that a
closing purchase transaction can be effected when the Fund so desires.

The purchaser of an option risks a total loss of the premium paid for the option
if the price of the underlying security does not increase or decrease
sufficiently to justify exercise. The seller of an option, on the other hand,
will recognize the premium as income if the option expires unrecognized but
forgoes any capital appreciation in excess of the exercise price in the case of
a call option and may be required to pay a price in excess of current market
value in the case of a put option. Options purchased and sold other than on an
exchange in private transactions also impose on the Fund the credit risk that
the counterparty will fail to honor its obligations. The Fund will not purchase
options if, as a result, the aggregate cost of all outstanding options exceeds
5% of the Fund's assets. To the extent that puts, straddles and similar
investment strategies involve instruments regulated by the Commodity Futures
Trading Commission, other 

                                      B-5
<PAGE>   55


than for hedging purposes, the aggregate initial margin and premiums required to
establish such positions will not exceed 5% of the Fund's total assets after
taking into account unrealized profits and unrealized losses on any such
contracts it has entered into.

WARRANTS AND RIGHTS

The Fund may invest up to 5% of its total assets in warrants or rights (other
than those acquired in units or attached to other securities) which entitle the
holder to buy equity securities at a specific price for or at the end of a
specific period of time.

Investing in rights and warrants can provide a greater potential for profit or
loss than an equivalent investment in the underlying security, and, thus, can be
a speculative investment. The value of a right or warrant may decline because of
a decline in the value of the underlying security, the passage of time, changes
in interest rates or in the dividend or other policies of the company whose
equity underlies the warrant or a change in the perception as to the future
price of the underlying security, or any combination thereof. Rights and
warrants generally pay no dividends and confer no voting or other rights other
than to purchase the underlying security.

INVESTMENTS IN INVESTMENT COMPANIES

The Fund may invest up to 10% of its total assets (5% per issuer) in securities
issued by other unaffiliated investment companies, although the Fund may not
acquire more than 3% of the voting securities of any investment company.

WHEN ISSUED, DELAYED DELIVERY SECURITIES AND FORWARD COMMITMENTS

The Fund may enter into forward commitments for the purchase or sale of
securities, including on a "when issued" or "delayed delivery" basis. In such
transactions, instruments are bought with payment and delivery taking place in
the future in order to secure what is considered to be an advantageous yield or
price at the time of the transaction. In some cases, a forward commitment may be
conditioned upon the occurrence of a subsequent event, such as approval and
consummation of a merger, corporate reorganization or debt restructuring, i.e.,
a when, as and if issued security. When such transactions are negotiated, the
price is fixed at the time of the commitment, with payment and delivery taking
place in the future, generally a month or more after the date of the commitment.
While the Fund will only enter into a forward commitment with the intention of
actually acquiring the security, the Fund may sell the security before the
settlement date if it is deemed advisable.

Securities purchased under a forward commitment are subject to market
fluctuation, and no interest (or dividends) accrues to the Fund prior to the
settlement date. The Fund will segregate with its custodian cash or liquid
securities in an aggregate amount at least equal to the amount of its
outstanding forward commitments. When the Fund engages in when-issued, delayed
delivery or forward commitment transactions, it relies on the other party to
consummate the trade. Failure of the other party to do so may result in the Fund
incurring a loss or missing an opportunity to obtain a price considered to be
advantageous.

SHORT SALES

The Fund may make short sales of securities. A short sale is a transaction in
which the Fund sells a security it does not own in anticipation that the market
price of that security will decline. The Fund expects to make short sales both
to obtain capital gains from anticipated declines in securities and as a form of
hedging to offset potential declines in long positions in the same or similar
securities. The short sale of a security is considered a speculative investment
technique.

When the Fund makes a short sale, it must borrow the security sold short and
deliver it to the broker-dealer through which it made the short sale in order to
satisfy its obligation to deliver the security upon 

                                      B-6
<PAGE>   56

conclusion of the sale. The Fund may have to pay a fee to borrow particular
securities and is often obligated to pay over any payments received on such
borrowed securities.

The Fund's obligation to replace the borrowed security will be secured by
collateral deposited with the broker-dealer, usually cash, U.S. government
securities or other liquid securities. The Fund will also be required to deposit
similar collateral with its Custodian to the extent, if any, necessary so that
the value of both collateral deposits in the aggregate is at all times equal to
the greater of the price at which the security is sold short or 100% of the
current market value of the security sold short. Depending on arrangements made
with the broker-dealer from which it borrowed the security regarding payment
over of any payments received by the Fund on such security, the Fund may not
receive any payments (including interest) on its collateral deposited with such
broker-dealer. If the price of the security sold short increases between the
time of the short sale and the time the Fund replaces the borrowed security, the
Fund will incur a loss; conversely, if the price declines, the Fund will realize
a capital gain. Any gain will be decreased, and any loss increased, by the
transaction costs described above. Although the Fund's gain is limited to the
price at which it sold the security short, its potential loss is theoretically
unlimited.

The market value of the securities sold short of any one issuer will not exceed
either 5% of the Fund's total assets or 5% of such issuer's voting securities.
The Fund will not make a short sale, if, after giving effect to such sale, the
market value of all securities sold short exceeds 5% of the value of its assets
or the Fund's aggregate short sales of a particular class of securities exceeds
5% of the outstanding securities of that class. The Fund may also make short
sales "against the box" without respect to such limitations. In this type of
short sale, at the time of the sale, the Fund owns or has the immediate and
unconditional right to acquire at no additional cost the identical security.

RESTRICTED AND ILLIQUID SECURITIES

The Fund may invest up to a total of 15% of its net assets in securities the
markets for which are illiquid, including repurchase agreements with more than
seven days to maturity. Within this 15% limitation, the Fund may invest up to 5%
of its net assets in the securities of unseasoned issuers. Illiquid securities
include securities the disposition of which is subject to substantial legal or
contractual restrictions. The sale of illiquid securities often requires more
time and results in higher brokerage charges or dealer discounts and other
selling expenses than does the sale of securities eligible for trading on
national securities exchanges or in the over-the-counter markets. Restricted
securities may sell at a price lower than similar securities that are not
subject to restrictions on resale. Unseasoned issuers are companies (including
predecessors) that have operated less than three years. The continued liquidity
of such securities is not as well assured as that of publicly traded securities,
and accordingly the Board of Directors will monitor their liquidity. The Board
will review pertinent factors such as trading activity, reliability of price
information and trading patterns of comparable securities in determining whether
to treat any such security as liquid for purposes of the foregoing 15% test. To
the extent the Board treats such securities as liquid, temporary impairments to
trading patterns of such securities may adversely affect the Fund's liquidity.

To the extent it can do so consistent with the foregoing limitations, the Fund
may invest in non-publicly traded securities, including securities that are not
registered under the Securities Act of 1933, as amended, but that can be offered
and sold to qualified institutional buyers under Rule 144A under that Act. The
Board of Directors has adopted guidelines and delegated to the Adviser, subject
to the supervision of the Board of Directors, the daily function of determining
and monitoring the liquidity of Rule 144A securities. Rule 144A securities may
become illiquid if qualified institutional buyers are not interested in
acquiring the securities.

REPURCHASE AGREEMENTS

The Fund may invest in repurchase agreements, which are agreements pursuant to
which securities are acquired by the Fund from a third party with the
understanding that they will be repurchased by the seller at a fixed price on an
agreed date. These agreements may be made with respect to any of the portfolio
securities in which the Fund is authorized to invest. Repurchase agreements may
be characterized as loans 

                                      B-7
<PAGE>   57

secured by the underlying securities. The Fund may enter into repurchase
agreements with (i) member banks of the Federal Reserve System having total
assets in excess of $500 million and (ii) securities dealers, provided that such
banks or dealers meet the creditworthiness standards established by the Fund's
Board of Directors ("Qualified Institutions"). The Adviser will monitor the
continued creditworthiness of Qualified Institutions, subject to the supervision
of the Board of Directors. The resale price reflects the purchase price plus an
agreed upon market rate of interest which is unrelated to the coupon rate or
date of maturity of the purchased security. The collateral is marked to market
daily. Such agreements permit the Fund to keep all its assets earning interest
while retaining "overnight" flexibility in pursuit of investment of a
longer-term nature. The following Information supplements that in the
Prospectus.

The use of repurchase agreements involves certain risks. For example, if the
seller of securities under a repurchase agreement defaults on its obligation to
repurchase the underlying securities, as a result of its bankruptcy or
otherwise, the Fund will seek to dispose of such securities, which action could
involve costs or delays. If the seller becomes insolvent and subject to
liquidation or reorganization under applicable bankruptcy or other laws, the
Fund's ability to dispose of the underlying securities may be restricted.
Finally, it is possible that the Fund may not be able to substantiate its
interest in the underlying securities. To minimize this risk, the securities
underlying the repurchase agreement will be held by the Fund's custodian at all
times in an amount at least equal to the repurchase price, including accrued
interest. If the seller fails to repurchase the securities, the Fund may suffer
a loss to the extent proceeds from the sale of the underlying securities are
less than the repurchase price. The Fund will not enter into repurchase
agreements of a duration of more than seven days if, taken together with all
other illiquid securities in the Fund's portfolio, more than 15% of its net
assets would be so invested.


LOANS OF PORTFOLIO SECURITIES

To increase income, the Fund may lend its portfolio securities to securities
broker-dealers or financial institutions if (1) the loan is collateralized in
accordance with applicable regulatory requirements including collateralization
continuously at no less than 100% by marking to market daily, (2) the loan is
subject to termination by the Fund at any time, (3) the Fund receives reasonable
interest or fee payments on the loan, (4) the Fund is able to exercise all
voting rights with respect to the loaned securities and (5) the loan will not
cause the value of all loaned securities to exceed 33 1/3% of the value of the
Fund's assets.

If the borrower fails to maintain the requisite amount of collateral, the loan
automatically terminates and the Fund could use the collateral to replace the
securities while holding the borrower liable for any excess of replacement cost
over the value of the collateral. As with any extension of credit, there are
risks of delay in recovery and in some cases even loss of rights in collateral
should the borrower of the securities fail financially.

BORROWING

The Fund may not borrow money except for (1) short-term credits from banks as
may be necessary for the clearance of portfolio transactions, and (2) borrowings
from banks for temporary or emergency purposes, including the meeting of
redemption requests, which would otherwise require the untimely disposition of
its portfolio securities. Borrowing may not, in the aggregate, exceed 15% of the
Fund's total assets after giving effect to the borrowing, and borrowing for
purposes other than meeting redemptions may not exceed 5% of the Fund's assets
after giving effect to the borrowing. The Fund will not make additional
investments when borrowings exceed 5% of assets. The Fund may mortgage, pledge
or hypothecate assets to secure such borrowings.

HEDGING TRANSACTIONS

FUTURES AND FORWARD CONTRACTS. The Fund may enter into futures and forward
contracts only for certain bona fide hedging and risk management purposes. The
Fund may enter into futures and forward contracts for the purchase or sale of
debt securities, debt instruments, or indices of prices thereof, stock index
futures, other financial indices, and U.S. Government Securities.

                                      B-8
<PAGE>   58

A "sale" of a futures contract (or a "short" futures position) means the
assumption of a contractual obligation to deliver the securities underlying the
contract at a specified price at a specified future time. A "purchase" of a
futures contract (or a "long" futures position) means the assumption of a
contractual obligation to acquire the securities underlying the contract at a
specified price at a specified future time.

Certain futures contracts are settled on a net cash payment basis rather than by
the sale and delivery of the securities underlying the futures contracts. U.S.
futures contracts have been designed by exchanges that have been designated as
"contract markets" by the Commodity Futures Trading Commission, an agency of the
U.S. Government, and must be executed through a futures commission merchant
(i.e., a brokerage firm) which is a member of the relevant contract market.
Futures contracts trade on these contract markets and the exchange's affiliated
clearing organization guarantees performance of the contracts as between the
clearing members of the exchange.

These contracts entail certain risks, including but not limited to the
following: no assurance that futures contracts transactions can be offset at
favorable prices, possible reduction of the Fund's yield due to the use of
hedging, possible reduction in value of both the securities hedged and the
hedging instrument, possible lack of liquidity due to daily limits on price
fluctuation, imperfect correlation between the contracts and the securities
being hedged, and potential losses in excess of the amount invested in the
futures contracts themselves.

CURRENCY TRANSACTIONS. The Fund may enter into various currency transactions,
including forward foreign currency contracts, currency swaps, foreign currency
or currency index futures contracts and put and call options on such contracts
or on currencies. A forward foreign currency contract involves an obligation to
purchase or sell a specific currency for a set price at a future date. A
currency swap is an arrangement whereby each party exchanges one currency for
another on a particular day and agrees to reverse the exchange on a later date
at a specific exchange rate. Forward foreign currency contracts and currency
swaps are established in the interbank market conducted directly between
currency traders (usually large commercial banks or other financial
institutions) on behalf of their customers. Futures contracts are similar to
forward contracts except that they are traded on an organized exchange and the
obligations thereunder may be offset by taking an equal but opposite position to
the original contract, with profit or loss determined by the relative prices
between the opening and offsetting positions. The Fund expects to enter into
these currency contracts and swaps in primarily the following circumstances: to
"lock in" the U.S. dollar equivalent price of a security the Fund is
contemplating to buy or sell that is denominated in a non-U.S. currency; or to
protect against a decline against the U.S. dollar of the currency of a
particular country to which the Fund's portfolio has exposure. The Fund
anticipates seeking to achieve the same economic result by utilizing from time
to time for such hedging a currency different from the one of the given
portfolio security as long as, in the view of the Adviser, such currency is
essentially correlated to the currency of the relevant portfolio security based
on historic and expected exchange rate patterns.

The Adviser may choose to use such instruments on behalf of the Fund depending
upon market conditions prevailing and the perceived investment needs of the
Fund. The swap market has grown substantially in recent years with a large
number of banks and investment banking firms acting both as principals and as
agents utilizing standardized swap documentation. As a result, the swap market
has become relatively broad and deep as compared to the markets for similar
instruments which are established in the interbank market. In accordance with
the current position of the staff of the Securities and Exchange Commission (the
"SEC"), the Fund will treat swap transactions as illiquid for purposes of the
Fund's policy regarding illiquid securities. Futures contracts, interest rate
swaps, and options on securities, indices and futures contracts and certain
currency contracts sold by the Fund are generally subject to segregation and
coverage requirements with the result that, if the Fund does not hold the
security or futures contract underlying the instrument, the Fund will be
required to segregate on an ongoing basis with its custodian, cash, U.S.
government securities, or other liquid securities in an amount at least equal to
the Fund's obligations with respect to such instruments. Such amounts fluctuate
as the obligations increase or decrease. The 

                                      B-9
<PAGE>   59

segregation requirement can result in the Fund maintaining securities positions
it would otherwise liquidate or segregating assets at a time when it might be
disadvantageous to do so.

The Fund expects that its investments in these currency transactions and the
futures and forward contracts described above will be less than 5% of its net
assets.

PORTFOLIO TURNOVER

The investment policies of the Fund may lead to frequent changes in investments,
particularly in periods of rapidly fluctuating interest or currency exchange
rates. The portfolio turnover may be higher than that of other investment
companies. While it is impossible to predict with certainty the portfolio
turnover, the Adviser expects that the annual turnover rate of the Fund will not
exceed 75%. Portfolio turnover generally involves some expense to the Fund,
including brokerage commissions or dealer mark-ups and other transaction costs
on the sale of securities and reinvestment in other securities. The portfolio
turnover rate is computed by dividing the lesser of the amount of the securities
purchased or securities sold by the average monthly value of securities owned
during the year (excluding securities whose maturities at acquisition were one
year or less).


                                   THE ADVISER

The Adviser is a New York limited liability company with principal offices
located at One Corporate Center, Rye, New York 10580-1434.

Pursuant to an Investment Advisory Contract, which was approved by the Fund's
sole shareholder on June 28, 1995, and last approved by the Board of Directors
on February 17, 1999, the Adviser furnishes a continuous investment program for
the Fund's portfolio, makes the day-to-day investment decisions for the Fund,
arranges the portfolio transactions for the Fund and generally manages the
Fund's investments in accordance with the stated policies of the Fund, subject
to the general supervision of the Board of Directors of the Fund.

Under the Investment Advisory Contract, the Adviser also (1) provides the Fund
with the services of persons competent to perform such supervisory,
administrative, and clerical functions as are necessary to provide efficient
administration of the Fund, including maintaining certain books and records and
overseeing the activities of the Fund's Custodian and Transfer Agent; (2)
oversees the performance of administrative and professional services provided to
the Fund by others, including the Fund's Custodian, Transfer Agent and Dividend
Disbursing Agent, as well as legal, accounting, auditing and other services
performed for the Fund; (3) provides the Fund, if requested, with adequate
office space and facilities; (4) prepares, but does not pay for, periodic
updating of the Fund's registration statement, Prospectus and Additional
Statement, including the printing of such documents for the purpose of filings
with the SEC; (5) supervises the calculation of the net asset value of shares of
the Fund; (6) prepares, but does not pay for, all filings under state "Blue Sky"
laws of such states or countries as are designated by the Distributor, which may
be required to register or qualify, or continue the registration or
qualification of, the Fund and/or its shares under such laws; and (7) prepares
notices and agendas for meetings of the Fund's Board of Directors and minutes of
such meetings in all matters required by the Investment Company Act of 1940, as
amended (the "1940 Act"), to be acted upon by the Board.

The Adviser has entered into a Sub-Administration Contract with BISYS Fund
Services L.P. (the "Sub-Administrator") pursuant to which the Sub-Administrator
provides certain administrative services necessary for the Fund's operations but
which do not concern the investment advisory and portfolio management services
provided by the Adviser. For such services and the related expenses borne by the
Sub-Administrator, the Adviser pays a prorated monthly fee at the annual rate of
 .0625% of the average net assets of the Fund (minimum annual fee of $30,000 per
portfolio) on the first $350 million of all of the funds advised by the Adviser
and its affiliates and administered by BISYS and .0425% of any net assets 

                                      B-10
<PAGE>   60

above $350 million, and .0225% of any assets above $700 million which, together
with the services to be rendered, is subject to negotiation between the parties
and both parties retain the right unilaterally to terminate the arrangement on
not less than 60 days' notice.

The Investment Advisory Contract provides that absent willful misfeasance, bad
faith, gross negligence or reckless disregard of its duty, the Adviser and its
employees, officers, directors and controlling persons are not liable to the
Fund or any of its investors for any act or omission by the Adviser or for any
error of judgment or for losses sustained by the Fund. However, the Investment
Advisory Contract provides that the Fund is not waiving any rights it may have
with respect to any violation of law which cannot be waived. The Investment
Advisory Contract also provides indemnification for the Adviser and each of
these persons for any conduct for which they are not liable to the Fund. The
Investment Advisory Contract in no way restricts the Adviser from acting as
adviser to others. The Fund has agreed by the terms of its Investment Advisory
Contract that the word "Gabelli" in its name is derived from the name of the
Adviser which in turn is derived from the name of Mario J. Gabelli; that such
name is the property of the Adviser for copyright and/or other purposes; and
that, therefore, such name may freely be used by the Adviser for other
investment companies, entities or products. The Fund has further agreed that in
the event that for any reason the Adviser ceases to be its investment adviser,
it will, unless the Adviser otherwise consents in writing, promptly take all
steps necessary to change its name to one which does not include "Gabelli."

The Investment Advisory Contract is terminable without penalty by the Fund on
not more than 60 days' written notice when authorized by the Directors of the
Fund; by the holders of a majority, as defined in the 1940 Act, of the
outstanding shares of the Fund; or by the Adviser. The Investment Advisory
Contract will automatically terminate in the event of its assignment, as defined
in the 1940 Act and rules thereunder, except to the extent otherwise provided by
order of the SEC or any rule under the 1940 Act and except to the extent the
1940 Act no longer provides for automatic termination, in which case the
approval of a majority of the disinterested Directors is required for any
"assignment." The Investment Advisory Contract provides that unless terminated
it will remain in effect from year to year, so long as continuance of the
Investment Advisory Contract is approved annually by the Directors, or the
shareholders of the Fund and in either case, by a majority vote of the Directors
who are not parties to the Investment Advisory Contract or "interested persons"
as defined in the 1940 Act of any such person cast in person, at a meeting
called specifically for the purpose of voting on the continuance of the
Investment Advisory Contract.

                                 THE DISTRIBUTOR

   
The Fund has entered into a Distribution Agreement with Gabelli & Company, Inc.
(the "Distributor"), a New York corporation which is a subsidiary of Gabelli
Funds, LLC, having principal offices located at One Corporate Center, Rye, New
York 10580-1434. The Distributor acts as agent of the Fund for the continuous
offering of its shares on a best efforts basis.
    


                                DISTRIBUTION PLAN

Pursuant to separate distribution and service plans (the Class A Plan, the Class
B Plan, the Class C Plan and the Class AAA Plan, collectively, the Plans)
adopted by the Fund pursuant to Rule 12b-1 under the 1940 Act and the
Distribution Agreement, the Distributor incurs the expenses of distributing the
Fund's Class A., 

                                      B-11

<PAGE>   61

Class B., Class C and Class AAA shares. In addition, the Distributor receives
the proceeds of contingent deferred sales charges paid by investors upon certain
redemptions of Class B and Class C shares.

The Class A, Class B, Class C and Class AAA Plans continue in effect from year
to year, provided that each such continuance is approved at least annually by a
vote of the Board of Directors, including a majority vote of the Directors who
are not interested persons of the Company and who have no direct or indirect
financial interest in the operation of the Class A, Class B, Class C or Class
AAA Plans (the Independent Directors), cast in person at a meeting called for
the purpose of voting on such continuance. The Plans may each be terminated at
any time, without penalty, by the vote of a majority of the Independent
Directors, or by the vote of the holders of a majority of the outstanding shares
of the applicable class of the Fund on not more than 30 days' written notice to
any other party to the Plans. The Plans may not be amended to increase
materially the amounts to be spent for the services described therein without
approval by the shareholders of the applicable class (by both Class A and Class
B shareholders, voting separately, in the case of material amendments to the
Class A Plan), and all material amendments are required to be approved by the
Board of Directors in the manner described above. Each Plan will automatically
terminate in the event of its assignment. The Fund will not be contractually
obligated to pay expenses incurred under any Plan if it is terminated or not
continued.

Pursuant to each Plan, the Board of Directors will review at least quarterly a
written report of the distribution expenses incurred on behalf of each class of
shares of the Fund by the Distributor. The report includes an itemization of the
distribution expenses and the purposes of such expenditures. In addition, as
long as the Plans remain in effect, the selection and nomination of Independent
Directors shall be committed to the Independent Directors.

Pursuant to the Distribution Agreement, the Fund has agreed to indemnify the
Distributor to the extent permitted by applicable law against certain
liabilities under the federal securities laws.

Pursuant to rules of the NASD, the Distributor is required to limit aggregate
initial sales charges, deferred sales charges and asset-based sales charges to
6.25% of total gross sales of each class of shares. Interest charges on
unreimbursed distribution expenses equal to the prime rate plus one percent per
annum may be added to the 6.25% limitation. Additional shares resulting from the
reinvestment of dividends and distributions are not included in the calculation
of the 6.25% limitation. The annual asset-based sales charge on shares of the
Fund may not exceed .75 of 1% per class. The 6.25% limitation applies to each
class of the Fund rather than on a per shareholder basis. If aggregate sales
charges were to exceed 6.25% of total gross sales of any class, all sales
charges on shares of the class would be suspended.

During the fiscal year ended December 31, 1998, the Distributor incurred
distribution expenses under the Distribution Plan for Class AAA of $206,400. Of
this amount $68,600 was spent on printing, postage and stationery, $56,500 on
overhead support expenses, $70,800 on salaries of personnel of the Distributor
and $10,500 to third party brokers. Pursuant to the Distribution Plan, the Fund
paid the Distributor $69,200, or .25% of its average daily net assets.

Shares of the Fund may also be purchased through shareholder agents that are not
affiliated with the Fund or the Distributor. There is no sales or service charge
imposed by the Fund other than as described, but agents who do not receive
distribution payments or sales charges may impose a charge to the investor for
their services. Such fees may vary among agents, and such agents may impose
higher initial or subsequent investment requirements than those established by
the Fund. Services provided by broker-dealers may include allowing the investor
to establish a margin account and to borrow on the value of the Fund's shares in
that account. It is the responsibility of the shareholder's agent to establish
procedures which would assure that upon receipt of an order to purchase shares
of the Fund the order will be transmitted so that it will be received by the
Distributor before the time when the price applicable to the buy order expires.

                             INVESTMENT RESTRICTIONS

The Fund's investment objective and the following investment restrictions are
fundamental and cannot be changed without the approval of the holders of a
majority of the Fund's outstanding voting securities (defined in the Act as the
lesser of (a) more than 50% of the outstanding shares or (b) 67% or more of the
shares represented at a meeting at which more than 50% of the outstanding shares
are represented). All other investment policies or practices are considered by
the Fund not to be fundamental and accordingly may be changed without
stockholder approval. If a percentage restriction on investment or use of assets
set forth below is adhered to at the time a transaction is effected, later
changes in percentage resulting from changing market values or total assets of
the Fund will not be considered a deviation from policy. The Fund may not:

         (1)  invest in more than 25% of the value of its total assets in any
              particular industry (this restriction does not apply to
              obligations issued or guaranteed by the U.S. government or its
              agencies or instrumentalities);

         (2)  issue senior securities, except that the Fund may borrow money
              from a bank, including on margin if margin securities are owned,
              in an amount up to 33 1/3% of its total assets (including the
              amount of such enumerated senior securities issued but excluding
              any liabilities and indebtedness not constituting senior
              securities) and except that the Fund may borrow up to an
              additional 5% of its total assets for temporary purposes; or
              pledge its assets other than to secure such issuances or in
              connection with hedging transactions, short sales, when-issued and
              forward commitment transactions and similar investment strategies;

         (3)  make loans of money or property to any person, except through
              loans of portfolio securities, the purchase of fixed income
              securities or the acquisition of securities subject to repurchase
              agreements;

         (4)  underwrite the securities of other issuers, except to the extent
              that in connection with the disposition of portfolio securities or
              the sale of its own shares the Fund may be deemed to be an
              underwriter;

         (5)  invest for the purpose of exercising control over management of 
              any company;

         (6)  purchase real estate or interests therein, including limited
              partnerships that invest primarily in real estate equity
              interests, other than publicly traded real estate investment
              trusts and publicly traded master limited partnership interests;
              or

         (7)  purchase or sell commodities or commodity contracts except for
              certain bona fide hedging, yield enhancement and risk management
              purposes or invest in any oil, gas or mineral leases.

In addition, as a diversified investment company, the Fund is subject to the
following limitations as to 75% of its total assets: (a) the Fund may not invest
more than 5% of its total assets in the securities of any one issuer, except
obligations of the U.S. Government and its agencies and instrumentalities, and
(b) the Fund may not own more than 10% of the outstanding voting securities of
any one issuer.


                      PORTFOLIO TRANSACTIONS AND BROKERAGE

The Adviser is authorized on behalf of the Fund to employ brokers to effect the
purchase or sale of portfolio securities with the objective of obtaining prompt,
efficient and reliable execution and clearance of such transactions at the most
favorable price obtainable ("best execution") at reasonable expense.
Transactions in securities other than those for which a securities exchange is
the principal market are generally done through a principal market maker.
However, such transactions may be effected through a 

                                      B-15
<PAGE>   65

                                                                            
brokerage firm and a commission paid whenever it appears that a broker can
obtain a more favorable overall price. In general, there may be no stated
commission in the case of securities traded on the over-the-counter markets, but
the prices of those securities may include undisclosed commissions or markups.
Options transaction will usually be effected through a broker and a commission
will be charged. The Fund also expects that securities will be purchased at
times in underwritten offerings where the price includes a fixed amount of
compensation generally referred to as the underwriter's concession or discount.

The Adviser currently serves as adviser to a number of investment company
clients and may in the future act as adviser to others. Affiliates of the
Adviser act as investment adviser to numerous private accounts. It is the
practice of the Adviser and its affiliates to cause purchase and sale
transactions to be allocated among the Fund and others whose assets they manage
in such manner as it deems equitable. In making such allocations among the Fund
and other client accounts, the main factors considered are the respective
investment objectives, the relative size of portfolio holdings of the same or
comparable securities, the availability of cash for investment, the size of
investment commitments generally held and the opinions of the persons
responsible for managing the portfolios of the Fund and other client accounts.

The policy of each Fund regarding purchases and sales of portfolio securities is
that primary consideration will be given to obtaining the most favorable prices
and efficient execution of transactions. In seeking to implement each Fund's
policies, the Adviser effects transactions with those brokers and dealers who
the Adviser believes provide the most favorable prices and are capable of
providing efficient executions. If the Adviser believes such price and execution
are obtainable from more than one broker or dealer, it may give consideration to
placing portfolio transactions with those brokers and dealers who also furnish
research and other services to each Fund or the Adviser of the type described in
Section 28(e) of the Securities Exchange Act of 1934. In doing so, each Fund may
also pay higher commission rates than the lowest available when the Adviser
believes it is reasonable to do so in light of the value of the brokerage and
research services provided by the broker effecting the transaction. Such
services may include, but are not limited to, any one or more of the following:
information as to the availability of securities for purchase or sale;
statistical or factual information or opinions pertaining to investment; wire
services; and appraisals or evaluations of portfolio securities.

Research services furnished by brokers or dealers through which the Fund effects
securities transactions are used by the Adviser and its advisory affiliates in
carrying out their responsibilities with respect to all of their accounts over
which they exercise investment discretion. Such investment information may be
useful only to one or more of the other accounts of the Adviser and its advisory
affiliates, and research information received for the commissions of those
particular accounts may be useful both to the Fund and one or more of such other
accounts. The purpose of this sharing of research information is to avoid
duplicative charges for research provided by brokers and dealers.

Neither the Fund nor the Adviser has any legally binding agreement with any
broker or dealer regarding any specific amount of brokerage commissions which
will be paid in recognition of such services. However, in determining the amount
of portfolio commissions directed to such brokers or dealers, the Adviser does
consider the level of services provided. Based on such determinations, the
Adviser has allocated brokerage commissions of $2,852 on portfolio transactions
in the principal amount of $836,286 during 1998, to various broker-dealers that
have provided research services to the Adviser.

The Adviser may also place orders for the purchase or sale of portfolio
securities with Gabelli & Company, Inc. ("Gabelli"), a broker-dealer member of
the National Association of Securities Dealers, Inc. and an affiliate of the
Adviser, when it appears that, as an introducing broker or otherwise, Gabelli
can obtain a price and execution which is at least as favorable as that
obtainable by other qualified brokers. The Adviser may also consider sales of
shares of the Fund and any other registered investment companies managed by the
Adviser and its affiliates by brokers and dealers other than the Distributor as
a factor in its selection of brokers and dealers to execute portfolio
transactions for the Fund.

The following table sets forth certain information regarding the brokerage
commissions paid and the brokerage commissions paid to Gabelli affiliates for
the fiscal years ended December 31, 1996 and 1997 and 1998.

1998.............................          $104,828              $   300
</TABLE>


For the fiscal year ended December 31, 1998 .30% of aggregate brokerage
commissions paid by the Fund were paid to Gabelli & Company, Inc., or .37% of
the Fund's aggregate dollar amount of transactions involving the payment of
commissions.

As required by Rule 17e-1 under the 1940 Act, the Board of Directors of the Fund
has adopted "Procedures" which provide that the commissions paid to Gabelli on
stock exchange transactions may not exceed that which would have been charged by
another qualified broker or member firm able to effect the same or a comparable
transaction at an equally favorable price. Rule 17e-1 and the Procedures contain
requirements that the Board, including independent Directors, conduct periodic
compliance reviews of such brokerage allocations and review such schedule at
least annually for its continuing compliance with the foregoing standard. The
Adviser and Gabelli are also required to furnish reports and maintain records in
connection with such reviews.

To obtain the best execution of portfolio trades on the New York Stock Exchange,
Inc. ("NYSE"), Gabelli controls and monitors the execution of such transactions
on the floor of the NYSE through independent "floor brokers" or through the
Designated Order Turnaround ("DOT") System of the NYSE. Such transactions are
then cleared, confirmed to the Fund for the account of Gabelli, and settled
directly with the Custodian of the Fund by a clearing house member firm which
remits the commission less its clearing charges to Gabelli. Gabelli may also
effect portfolio transactions on behalf of the Fund in the same manner and
pursuant to the same arrangements on other national securities exchanges which
adopt direct access rules similar to those of the NYSE.


                        PURCHASE AND REDEMPTION OF SHARES

PURCHASE OF SHARES

Shares of Class A, Class B and Class C of the Fund may be purchased at a price
equal to the next determined net asset value per share plus a sales charge
which, at the election of the investor, may be imposed either (i) at the time or
purchase (Class A shares) or (ii) on a deferred basis (Class B of Class C
shares.) Class AAA shares of the Fund are offered exclusively to clients of
Gabelli & Company, Inc., [the Fund or through any financial intermediary that
makes Class AAA shares available.] No minimum initial investment is required for
officers, directors or full-time employees of the Fund, other investment
companies managed by the Adviser, the Adviser, the Sub-Administrator, the
Transfer agent, the Distributor or their affiliates, including members of the
"immediate family" of such individuals and retirement plans and trusts for their
benefit. The term "immediate family" refers to spouses, children and
grandchildren (adopted or natural), parents, grandparents, siblings, a spouse's
siblings, a sibling's spouse and a sibling's children.

Each class of shares represents an interest in the same assets of the Fund and
is identical in all respects except that (i) each class is subject to different
sales charges and distribution and/or service fees (except for Class AAA shares,
which are not subject to any sales charges), which will affect performance
differently, 

                                      B-17
<PAGE>   67


(ii) each class has exclusive voting rights with respect to any matter submitted
to shareholders that relates solely to its arrangement and has separate voting
rights on any matter submitted to shareholders in which the interests of one
class differ from the interests of any other class, (iii) each class has a
different exchange privilege, (iv) only Class B shares have a conversion
feature, (v) Class AAA shares are offered exclusively to investors acquiring
shares directly from the Distributor, or from a financial intermediary with whom
the Distributor has entered into an agreement expressly authorizing the sale by
such intermediary of Class AAA shares.

Under the current distribution arrangement between each Class and the
Distributor, Class A shares are sold at a maximum sales charge of 5.75% and
Class B *, Class C * and Class AAA shares are sold at net asset value.

Class B shares automatically convert to Class A shares of the Fund on the first
business day of the eighty-fifth calendar month following the calendar month in
which such shares were issued. The automatic conversion of Class B shares to
Class A shares may be suspended by the Board of Directors at any time it
determines such suspension to be required under applicable law or in the
exercise of their fiduciary duties; provided, however, that if the Board
determines that the suspension is likely to continue for a substantial period of
time, the Board of Directors will seek to create an additional class or
additional classes of shares into which Class B shares are eligible for
conversion under the rules of the Securities and Exchange Commission and other
applicable law.

If an investor or eligible group of related investors purchases Class A shares
of the Fund concurrently with Class A shares of other Gabelli funds, the
purchases may be combined to take advantage of the reduced sales charges
applicable to larger purchases.

An eligible group of related Fund investors includes any combination of the
following:

- -        an individual;

- -        the individual's spouse, their children and their parents;

- -        the individual's and spouse's Individual Retirement Accounts (IRA);

- -        any company controlled by the individual (a person, entity or group
         that holds 25% or more of the outstanding voting securities of a
         company will be deemed to control the company, and a partnership will
         be deemed to be controlled by each of its general partners.);

- -        a trust created by the individual, the beneficiaries of which are the
         individual, his or her spouse, parents and/or children;

- -        a Uniform Gift to Minors Act/Uniform Transfers to Minors Act account
         created by the individual or the individual's spouse; and

- -        one or more employee benefit plans of a company controlled by an
         individual.

In addition, an eligible group of related Fund investors may include an employer
(or group of related employers) and one or more retirement or group plans of
such employer or employers (an employer controlling, controlled by or under
common control with another employer is deemed related to that employer.)

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

* Class B and Class C shares are subject to a contingent deferred sales charge
  on certain redemptions.


                                      B-18

<PAGE>   68
The Distributor must be notified at the time of purchase that the investor is
entitled to a reduced sales charge. The reduced sales charge will be granted
subject to confirmation of the investor's holdings.

Rights of Accumulation. Reduced sales charges are also available through rights
of accumulation, under which an investor or an eligible group of related
investors, as described above, may aggregate the value of their existing
holdings of shares of the Fund and shares of other funds managed by the Adviser
or an affiliate (excluding money market funds other than those acquired pursuant
to the exchange privilege) to determine the reduced sales charge. The value of
existing holdings for purposes of determining the reduced sales charge is
calculated using the maximum offering price (net asset value plus maximum sales
charge) as of the previous business day.

Letters of Intent. Reduced sales charges are also available to investors (or an
eligible group of related investors), including retirement and group plans, who
enter into a written letter of intent (a "Letter of Intent") providing for the
purchase, within a thirteen-month period, of shares of the Fund and shares of
other funds managed by the Adviser or an affiliate (an "Investment Letter of
Intent"). Retirement and group plans may also qualify to purchase Class A shares
at net asset value by entering into a Letter of Intent whereby they agree to
enroll, within a thirteen-month period, a specified number of eligible employees
or participants (a "Participant Letter of Intent.").

For purposes of the Investment Letter of Intent, all shares of the Fund and
shares of other Gabelli funds (excluding money market funds other than those
acquired pursuant to the exchange privilege) which were previously purchased and
are still owned are also included in determining the applicable reduction.

A Letter of Intent permits a purchaser, in the case of an Investment Letter of
Intent, to establish a total investment goal to be achieved by any number of
investments over a thirteen-month period and, in case of a Participant Letter of
Intent, to establish a minimum eligible employee or participant enrollment goal
over a thirteen-month period. Each investment made during the period, in the
case of an Investment Letter of Intent, will receive the reduced sales charge
applicable to the amount represented by the goal, as if it were a single
investment. In the case of a Participant Letter of Intent, each investment made
during the period will be made at net asset value. Escrowed Class A shares
totaling 5% of the dollar amount of the Letter of Intent will be held by the
Transfer Agent in the name of the purchaser, except in the case of retirement
and group plans where the employer or plan sponsor will be responsible for
paying any applicable sales charge. The effective date of an Investment Letter
of Intent (except in the case of retirement and group plans) may be back-dated
up to 90 days, in order that any investments made during this 90-day period,
valued at the purchaser's cost, can be applied to the fulfillment of the Letter
of Intent goal.

The Investment Letter of Intent does not obligate the investor to purchase, nor
the Fund to sell, the indicated amount. Similarly, the Participant Letter of
Intent does not obligate the retirement or group plan to enroll the indicated
number of eligible employees or participants. In the event the Letter of Intent
goal is not achieved within the thirteen-month period, the purchaser (or the
employer or plan sponsor, in case of any retirement or group plan) is required
to pay the difference between the sales charge otherwise applicable to the
purchases actually made during this period and sales charges actually paid. Such
payment may be made directly to the Distributor or, if not paid, the Distributor
will liquidate sufficient escrowed shares to obtain such difference. Investors
electing to purchase Class A shares of the Fund pursuant to a Letter of Intent
should carefully read such Letter of Intent.

The Distributor must be notified at the time of purchase that the investor is
entitled to a reduced sales charge. The reduced sales charge will, in the case
of an Investment Letter of Intent, be granted subject to confirmation of the
number of eligible employees or participants in the retirement or group plan.
Letters of Intent are not available to individual participants in any retirement
or group plans.

Waiver of Contingent Deferred Sales Charge - Class B Shares. The contingent
deferred sales charge is waived under the circumstances described in the Fund's
Prospectus and the accompanying Owner's

                                      B-19

Manual. In connection with these waivers, the Transfer Agent will require the
shareholder to submit the supporting documentation set forth below.

The Transfer Agent reserves the right to request such additional documents as it
may deem appropriate.

REDEMPTION OF SHARES

Payment of the redemption price for shares redeemed may be made either in cash
or in portfolio securities (selected at the discretion of the Board of Directors
of the Fund and taken at their value used in determining the Fund's net asset
value per share as we described under "Net Asset Value" below), or partly in
cash and partly in portfolio securities. However, payments will be made wholly
in cash unless the Board of Directors believes that economic conditions exist
which would make such a practice detrimental to the best interest of the Fund.
If payment for shares redeemed is made wholly or partly in portfolio securities,
brokerage costs may be incurred by the investor in converting the securities to
cash. The Fund will not distribute in-kind portfolio securities that are not
readily marketable. The Fund has filed a formal election with the SEC pursuant
to which the Fund will only effect a redemption in portfolio securities where
the particular shareholder of record is redeeming more than $250,000 or 1.00% of
the Fund's total net assets, whichever is less, during any 90-day period. In the
opinion of the Fund's management, however, the amount of a redemption request
would have to be significantly greater than $250,000 before a redemption wholly
or partly in portfolio securities would be made.

Cancellation of purchase orders for Fund shares (as, for example, when checks
submitted to purchase shares are returned unpaid) causes a loss to be incurred
when the net asset value of the Fund shares on the date of cancellation is less
than on the original date of purchase. The investor is responsible for such
loss, 

                                      B-20

<PAGE>   70

and the Fund may reimburse itself or the Distributor for such loss by
automatically redeeming shares from any account registered at any time in that
shareholder's name, or by seeking other redress. In the event shares held in the
account of such shareholder are not sufficient to cover such loss, the
Distributor will promptly reimburse the Fund for the amount of such unrecovered
loss.

To minimize expenses, the Fund reserves the right to redeem, upon not less than
30 days' notice, all shares of the Fund in an account (other than an Individual
Retirement Account ("IRA")) which as a result of shareholder redemption has a
value below $500 and has reserved the ability to raise this amount to up to
$10,000. However, a shareholder will be allowed to make additional investments
prior to the date fixed for redemption to avoid liquidation of the account.

                               EXCHANGE PRIVILEGE

The Fund makes available to its shareholders the privilege of exchanging their
shares for shares of certain other funds managed by the Adviser or an affiliate,
including one or more specified money market funds, subject in each case to the
minimum investment requirements of each fund (the "Exchange Privilege"). Shares
of such other Gabelli Funds may also be exchanged for shares of the Fund. All
exchanges are made on the basis of the relative NAV next determined after
receipt of an order in proper form. An exchange will be treated as a redemption
and purchase for tax purposes. Shares may be exchanged for shares of another
fund only if shares of such fund may legally be sold under applicable state
laws. For retirement and group plans having a limited menu of Gabelli funds, the
Exchange Privilege is available for those funds eligible for investment in the
particular program.

CLASS A SHARES

Shareholders of the Fund may exchange their Class A shares for Class A shares of
any other fund managed by the Adviser or an affiliate that offers Class A shares
and for shares of any money market fund managed by the Adviser or an affiliate
on the basis of relative NAV. No fee or sales load will be imposed upon the
exchange. Shareholders of money market funds who acquired such shares upon
exchange of Class A shares may use the Exchange Privilege only to acquire Class
A shares of the Gabelli funds participating in the Exchange Privilege as
identified by the Distributor from time to time.

CLASS B AND CLASS C SHARES

Shareholders of the Fund may exchange their Class B and Class C shares for Class
B and Class C shares, respectively, of any other fund managed by the Adviser or
an affiliate that offers Class B or Class C shares on the basis of relative NAV
and for shares of any money market fund managed by the Adviser or an affiliate.
No CDSC will be payable upon such exchange, but a CDSC may be payable upon the
redemption of the Class B and Class C shares acquired as a result of an
exchange. The applicable sales charge will be that imposed by the fund in which
shares were initially purchased and the purchase date will be deemed to be the
first day of the month after the initial purchase, rather than the date of the
exchange.

At any time after acquiring shares of other funds participating in the Class B
or Class C Exchange Privilege, a shareholder may again exchange those shares
(and any reinvested dividends and distributions) for Class B and Class C shares
of the Fund, respectively, without subjecting such shares to any CDSC upon the
exchange. Shares of any fund participating in the Class B or Class C exchange
privilege that were acquired through reinvestment of dividends or distributions
may be exchanged for Class B or Class C shares, respectively, of other funds
without being subject to any CDSC.

CLASS AAA SHARES

Class AAA shares may be exchanged for Class AAA shares of any other funds
managed by the Adviser or an affiliate of the Adviser that offers Class AAA
shares or any other shares not subject to a front end load or CDSC. 

                                      B-21
<PAGE>   71


Additional details about the Exchange Privilege and prospectuses for each of the
funds managed by the Adviser or an affiliate are available from the Fund's
Transfer Agent. The Exchange Privilege may be modified, terminated or suspended
on sixty days' notice, and any fund, or the Distributor, has the right to reject
any exchange application relating to such fund's shares.


                                 NET ASSET VALUE

Net asset value is calculated separately for each class of the Fund. The net
asset value of Class B and Class C shares of the Fund will generally be lower
than the net asset value of Class A or Class AAA shares as a result of the
larger distribution-related fee to which Class B and Class C shares are subject.
It is expected, however, that the net asset value per share of each class will
tend to converge immediately after the recording of dividends, if any, which
will differ by approximately the amount of the distribution and/or service fee
expense accrual differential among the classes.

For purposes of determining the Fund's net asset value per share, readily
marketable portfolio securities listed on the NYSE are valued, except as
indicated below, at the last sale price reflected at the close of the regular
trading session of the NYSE on the business day as of which such value is being
determined. If there has been no sale on such day, the securities are valued at
the mean of the closing bid and asked prices on such day. If no asked prices are
quoted on such day, then the security is valued at the closing bid price on such
day. If no bid or asked prices are quoted on such day, then the security is
valued by such method as the Board of Directors shall determine in good faith to
reflect its fair market value. Readily marketable securities not listed on the
NYSE but listed on other national securities exchanges or admitted to trading on
the National Association of Securities Dealers Automated Quotations, Inc.
("NASDAQ") National List are valued in like manner.

Readily marketable securities traded in the over-the-counter market, including
listed securities whose primary market is believed by the Adviser to be
over-the-counter but excluding securities admitted to trading on the NASDAQ
National List, are valued at the mean of the current bid and asked prices as
reported by NASDAQ or, in the case of securities not quoted by NASDAQ, the
National Quotation Bureau or such other comparable sources as the Board of
Directors deems appropriate to reflect their fair value. If no bid or asked
prices are quoted on such day, then the security is valued by such method as the
Board of Directors shall determine in good faith to reflect its fair market
value.

Portfolio securities traded on more than one national securities exchange or
market are valued according to the broadest and most representative market as
determined by the Adviser. Securities traded primarily on foreign exchanges are
valued at the closing price on such foreign exchange immediately prior to the
close of the NYSE.

United States Government obligations and other debt instruments having sixty
days or less remaining until maturity are stated at amortized cost. Debt
instruments having a greater remaining maturity will be valued at the highest
bid price obtained from a dealer maintaining an active market in that security
or on the basis of prices obtained from a pricing service approved as reliable
by the Board of Directors. All other investment assets, including restricted and
not readily marketable securities, are valued under procedures established by
and under the general supervision and responsibility of the Fund's Board of
Directors designed to reflect in good faith the fair value of such securities.


                       DIVIDENDS, DISTRIBUTIONS AND TAXES

GENERAL

The Fund will determine either to distribute or to retain all or part of any net
long-term capital gains in any year for reinvestment. If any such gains are
retained, the Fund will be subject to a tax of 35% of such 

                                      B-22
<PAGE>   72

amount. In that event, the Fund expects that it will designate the retained
amount as undistributed capital gains in a notice to its shareholders, each of
whom (1) will be required to include in income for tax purposes as long-term
capital gains, its share of the undistributed amount, (2) will be entitled to
credit its proportionate share of the tax paid by the Fund against its federal
income tax liability and to claim refunds to the extent the credit exceeds such
liability, and (3) will increase its basis in its shares of the Fund by an
amount equal to 65% of the amount of undistributed capital gains included in
such shareholder's gross income.

Under the Code, amounts not distributed on a timely basis in accordance with a
calendar year distribution requirement are subject to a nondeductible 4% excise
tax. To avoid the tax, the Fund must distribute during each calendar year, an
amount equal to, at the minimum, the sum of (1) 98% of its ordinary income (not
taking into account any capital gains or losses) for the calendar year, (2) 98%
of its capital gains in excess of its capital losses for the twelve-month period
ending on October 31 of the calendar year (unless an election is made by the
Fund with a November or December year-end to use the Fund's fiscal year), and
(3) all ordinary income and net capital gains for previous years that were not
previously distributed. A distribution will be treated as paid during the
calendar year if it is paid during the calendar year or declared by the Fund in
October, November or December of the year, payable to shareholders of record on
a date during such month and paid by the Fund during January of the following
year. Any such distributions paid during January of the following year will be
deemed to be received on December 31 of the year the distributions are declared,
rather than when the distributions are received.

Gains or losses on the sales of securities by the Fund will be long-term capital
gains or losses if the securities have been held by the Fund for more than
twelve months. The Fund has qualified and intends to continue to qualify as a
regulated investment company under Subchapter M of the Code. If so qualified,
the Fund will not be subject to federal income tax on its net investment income
and net short-term capital gains, if any, realized during any fiscal year in
which it distributes such income and capital gains to its shareholders.

HEDGING TRANSACTIONS

Certain options, futures contracts and options on futures contracts are "section
1256 contracts." Any gains or losses on section 1256 contracts are generally
considered 60% long-term and 40% short-term capital gains or losses ("60/40").
Also, section 1256 contracts held by the Fund at the end of each taxable year
are "marked-to-market" with the result that unrealized gains or losses are
treated as though they were realized and the resulting gain or loss is treated
as 60/40 gain or loss.

Generally, the hedging transactions undertaken by the Fund may result in
"straddles" for U.S. federal income tax purposes. The straddle rules may affect
the character of gains (or losses) realized by the Fund. In addition, losses
realized by the Fund on positions that are part of a straddle may be deferred
under the straddle rules, rather than being taken into account in calculating
the taxable income for the taxable year in which such losses are realized.

Further, the Fund may be required to capitalize, rather than deduct currently,
any interest expense on indebtedness incurred or continued to purchase or carry
any positions that are a part of a straddle. Because only a few regulations
implementing the straddle rules have been promulgated, the tax consequences of
hedging transactions to the Fund are not entirely clear.

The Fund may make one or more of the elections available under the Code which
are applicable to straddles. If the Fund makes any of the elections, the amount,
character and timing of the recognition of gains or losses from the affected
straddle positions will be determined under rules that vary according to the
election(s) made. The rules applicable under certain of the elections accelerate
the recognition of gains or losses from the affected straddle positions. Because
application of the straddle rules may affect the character of gains or losses,
defer losses and/or accelerate the recognition of gains or losses from the
affected straddle positions, and require the capitalization of interest expense,
the amount which must be 

                                     B-23
<PAGE>   73


distributed to shareholders, and which will be taxed to shareholders as ordinary
income or long-term capital gain, may be increased or decreased substantially as
compared to a fund that did not engage in such hedging transactions.

DISTRIBUTIONS

Distributions of investment company taxable income (which includes taxable
interest and dividend income and the excess of net short-term capital gains over
long-term capital losses) are taxable to a U.S. shareholder as ordinary income,
whether paid in cash or shares. Dividends paid by the Fund will qualify for the
70% deduction for dividends received by corporations to the extent the Fund's
income consists of qualified dividends received from U.S. corporations.
Distributions of net capital gains (which consists of the excess of long-term
capital gains over net short-term capital losses), if any, are taxable as
long-term capital gains, whether paid in cash or in shares, and are not eligible
for the dividends received deduction. Shareholders receiving distributions in
the form of newly issued shares will have a basis in such shares of the Fund
equal to the fair market value of such shares on the distribution date. If the
net asset value of shares is reduced below a shareholder's cost as a result of a
distribution by the Fund, such distribution will be taxable even though it
represents a return of invested capital. The price of shares purchased may
reflect the amount of the forthcoming distribution. Those purchasing at that
time will receive a distribution which will nevertheless be taxable to them.

SALES OF SHARES

Upon a sale or exchange of his or her shares, a shareholder will realize a
taxable gain or loss depending upon his or her basis in the shares. Such gain or
loss will be treated as a long-term or short-term, generally depending upon the
shareholder's holding period for the shares. Any loss realized on a sale or
exchange will be disallowed to the extent the shares disposed of are replaced,
including replacement through reinvestment of dividends and capital gains
distributions in the Fund, within a period of 61 days beginning 30 days before
and ending 30 days after the shares are disposed of. In such case, the basis of
the shares acquired will be adjusted to reflect the disallowed loss.

Any loss realized by a shareholder on the sale of the Fund's shares held by the
shareholder for six months or less will be treated for tax purposes as a
long-term capital loss to the extent of any distributions of net capital gains
received by the shareholder with respect to such shares.

BACKUP WITHHOLDING

The Fund may be required to withhold federal income tax at the rate of 31% of
all taxable distributions payable to shareholders who fail to provide the Fund
with their correct taxpayer identification number or to make required
certifications, or who have been notified by the Internal Revenue Service that
they are subject to backup withholding. Backup withholding is not an additional
tax. Any amounts withheld may be credited against a shareholder's federal income
tax liability.


FOREIGN WITHHOLDING TAXES

Income received by the Fund from sources within foreign countries may be subject
to withholding and other taxes imposed by such countries. Tax conventions
between certain countries and the United States may reduce or eliminate such
taxes. It is impossible to determine the rate of foreign tax in advance since
the amount of the Fund's assets to be invested in various countries is not
known. Because the Fund may have more than 50% of its total assets invested in
securities of foreign corporations, the Fund may be entitled to "pass-through"
to shareholders the amount of foreign taxes paid by the Fund. Shareholders are
urged to consult their attorneys or tax advisers regarding specific questions as
to federal, state or local taxes.

CREATION OF ADDITIONAL SHARES

The Fund reserves the right to create and issue a number of series shares, in
which case the shares of each series would participate equally in the earnings,
dividends, and assets of the particular series and would vote separately to
approve management agreements or changes in investment policies, but shares of
all series would vote together in the election or selection of Directors,
principal underwriters and auditors and on any proposed material amendment to
the Fund's Certificate of Incorporation.

Upon liquidation of the Fund or any series, shareholders of the affected series
would be entitled to share pro rata in the net assets of their respective series
available for distribution to such shareholder.


                       INVESTMENT PERFORMANCE INFORMATION

In its reports, investor communications or advertisements, the Fund may include:
(i) its total return performance; (ii) its performance compared with various
indexes or other mutual funds; (iii) published evaluations by nationally
recognized ranking services and financial publications; (iv) descriptions and
updates concerning its strategies and portfolio investments; (v) its goals, risk
factors and expenses compared with other mutual funds; (vi) analysis of its
investments by industry, country, credit quality and other characteristics;
(vii) a discussion of the risk/return continuum relating to different
investments; (viii) the potential impact of adding foreign stocks to a domestic
portfolio; (ix) the general biography or work experience of the portfolio
manager of the Fund; (x) portfolio manager commentary or market updates; (xi)
discussion of macroeconomic factors affecting the Fund and its investments; and
(xii) other information of interest to investors. "Total return" represents the
annual percentage change in value of $1,000 invested at the maximum public
offering price for the one-year period and the life of the Fund through the most
recent calendar quarter, assuming reinvestment of all dividends and
distributions. The Fund may also furnish total return calculations for these and
other periods, based on investments at various sales charge levels or net asset
value. Any performance data which is based on the Fund's net asset value per
share would be reduced if a sales charge were taken into account.

Quotations of yield will be based on the investment income per share earned
during a particular 30-day period, less expenses accrued during the period ("net
investment income") and will be computed by dividing net investment income by
the maximum offering price per share on the last day of the period, according to
the following formula:

                                      A - B
                                      -----
                            YIELD = 2[ (cd + 1)6 - 1]

where a = dividends and interest earned during the period, b = expenses accrued
for the period (net of any reimbursements), c = the average daily number of
shares outstanding during the period that were entitled to receive dividends,
and d = the maximum offering price share on the last day of the period.

   
For the 30-day period ended December 31, 1998 the Fund's yield for Class AAA
shares was (0.87)%.
    

Quotations of total return will reflect only the performance of a hypothetical
investment in the Fund during the particular time period shown. The Fund's total
return and current yield may vary from time to time depending on market
conditions, the compositions of its portfolio and operating expenses. These
factors and possible differences in the methods used in calculating yield should
be considered when comparing the Fund's current yield to yields published for
other investment companies and other investment vehicles. Total return and yield
should also be considered relative to changes in the value of the Fund's shares
and the risks associated with the Fund's investment objectives and policies. At
any time in the future, total returns and yield may be higher or lower than past
total returns and yields and there can be no assurance that any historical
return or yield will continue.

From time to time evaluations of performance are made by independent sources
that may be used in advertisements concerning the Fund. These sources include:
Lipper Analytical Services, CDA/ Weisenberger Investment Company Service,
Barron's, Business Week, Changing Times, Financial World, Forbes, Fortune,
Money, Personal Investor, Sylvia Porter's Personal Finance, Bank Rate Monitor,
Morningstar and The Wall Street Journal.

In connection with communicating its yield or total return to current or
prospective shareholders, the Fund may also compare these figures to the
performance of other mutual funds tracked by mutual fund rating services or to
other unmanaged indexes which may assume reinvestment of dividends but generally
do not reflect deductions for administrative and management costs.

Quotations of the Fund's total return will represent the average annual
compounded rate of return of a hypothetical investment in the Fund over periods
of 1, 5, and 10 years (up to the life of the Fund), and are calculated pursuant
to the following formula:

                                 P(1+T)(n) = ERV

where P = a hypothetical initial payment of $1,000, T = the average annual total
return, n = the number of years, and ERV = the redeemable value at the end of
the period of a $1,000 payment made at the beginning of the period. All total
return figures will reflect the deduction of Fund expenses (net of certain
expenses reimbursed by the Adviser) on an annual basis, and will assume that all
dividends and distributions are reinvested and will deduct the maximum sales
charge, if any is imposed.

For the year ended December 31, 1998, the Fund's total return for Class AAA
shares was 17.4%. The average annual total return since its inception on June
30, 1995 is 16.1%.

incorporated by reference to the Fund's Annual Report dated December 31, 1998.
    

              DESCRIPTION OF SHARES, VOTING RIGHTS AND LIABILITIES

The Fund is an open-end management investment company that was organized as a
Maryland corporation on May 25, 1994. Its authorized capital stock consists of
one billion shares of stock having a par value of one tenth of one cent ($.001)
per share. The Fund is not required, and does not intend, to hold regular annual
shareholder meetings, but may hold special meetings for consideration of
proposals requiring shareholder approval, such as changing fundamental policies
or upon the written request of 10% of the 

                                      B-26
<PAGE>   76

Fund's shares to replace its Directors. The Fund's Board of Directors is
authorized to divide the unissued shares into separate series of stock, each
series representing a separate, additional portfolio.

There are no conversion or preemptive rights in connection with any shares of
the Fund. All shares, when issued in accordance with the terms of the offering,
will be fully paid and nonassessable. Shares will be redeemed at net asset
value, at the option of the shareholder.

The Fund sends semi-annual and audited annual reports to all shareholders which
include lists of portfolio securities and the Fund's financial statements, which
shall be audited annually. Unless it is clear that a shareholder is a nominee
for the account of an unrelated person or a shareholder otherwise specifically
requests in writing, the Fund may send a single copy of semi-annual, annual and
other reports to shareholders to all accounts at the same address and all
accounts of any person at that address.

The shares of the Fund have noncumulative voting rights which means that the
holders of more than 50% of the shares can elect 100% of the Directors if the
holders choose to do so, and, in that event, the holders of the remaining shares
will not be able to elect any person or persons to the Board of Directors.
Unless specifically requested by an investor who is a shareholder of record, the
Fund does not issue certificates evidencing shares.

                 APPENDIX TO STATEMENT OF ADDITIONAL INFORMATION

      DESCRIPTION OF MOODY'S INVESTORS SERVICE, INC. ("MOODY'S") CORPORATE
                                  BOND RATINGS

AAA: Bonds which are rated Aaa are judged to be of the best quality. They carry
the smallest degree of investment risk and are generally referred to as "gilt
edge." Interest payments are protected by a large or 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 which are rated Aa are
judged to be of high quality by all standards. Together with the Aaa group they
comprise what are generally known as high grade bonds. They are rated lower than
the best bonds because margins of protection may not be as large as in Aaa
securities or fluctuation of protective elements may be of greater amplitude or
there may be other elements present which made 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 sometime in the future. BAA: Bonds which 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. BA: Bonds which are rated Ba are judged to have
speculative elements; their future cannot be considered as well assured. Often
the protection of interest and principal payments may be very moderate and
thereby not well safeguarded during both good and bad times over the future.
Uncertainty of position characterizes bonds in this class. B: Bonds which are
rated B generally lack characteristics of the desirable investment. Assurance of
interest and principal payments or of maintenance of other terms of the contract
over any long period of time may be small. CAA: Bonds which are rated Caa are of
poor standing. Such issues may be in default or there may be present elements of
danger with respect to principal or interest. CA: Bonds which are rated Ca
represent obligations which are speculative in a high degree. Such issues are
often in default or have other marked shortcomings. C: Bonds which are rated C
are the lowest rated class of bonds and issues so rated can be regarded as
having extremely poor prospects of ever attaining any real investment standing.

NOTE: Moody's may apply numerical modifiers, 1, 2 and 3 in each generic rating
classification from Aa through B in its corporate bond rating system. The
modifier 1 indicates that the security ranks in the higher end of its generic
rating category; the modifier 2 indicates a mid-range ranking; and the modifier
3 indicates that the issue ranks in the lower end of its generic rating
category.


      DESCRIPTION OF STANDARD & POOR'S RATINGS SERVICES ("S&P'S") CORPORATE
                                  DEBT RATINGS

AAA: Debt rated AAA has the highest rating assigned by S&P's. Capacity to pay
interest and repay principal is extremely strong. AA: Debt rated AA has a very
strong capacity to pay interest and repay principal and differs from the highest
rated issues only in small degrees. A: Debt rated A has a strong capacity to pay
interest and repay principal although it is somewhat more susceptible to the
adverse effects of changes in circumstances and economic conditions than debt in
higher-rated categories. BBB: Debt rated BBB is regarded as having adequate
capacity to pay interest and repay principal. Whereas it normally exhibits
protection parameters, adverse economic conditions or changing circumstances are
more likely to lead to a weakened capacity to pay interest and repay principal
for debt in this category than for debt in higher rated categories. BB, B, CCC,
CC, C: Debt rated BB, B, CCC, CC and C is regarded, on balance, as predominantly
speculative with respect to capacity to pay interest and repay principal in
accordance with the terms of the obligation. BB indicates the lowest degree of
speculation and C the highest degree of speculation. While such debt will likely
have some quality and protective characteristics, these are outweighed by large
uncertainties or major risk exposures to adverse conditions. CI: The rating CI
is reserved for income bonds on which no interest is being paid. D: Debt rated D
is in payment default. The D rating category is used when interest payments or
principal payments are not made on the date due 

                                      B-28
<PAGE>   78

even if the applicable grace period has not expired, unless S&P's believes that
such payments will be made during such grace period. The D rating also will be
used upon the filing of a bankruptcy petition if debt service payments are
jeopardized. PLUS (+) OR MINUS (-): The ratings from "AA" to "CCC" may be
modified by the addition of a plus or minus sign to show relative standing
within the major rating categories.

R: The "r" symbol is attached to derivative, hybrid and certain other
obligations that S&P believes may experience high volatility or high variability
in expected returns due to non-credit risks created by the terms of the
obligation.

                 DESCRIPTION OF MOODY'S PREFERRED STOCK RATINGS

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

NOTE: Moody's may apply numerical modifiers 1, 2 and 3 in each rating
classification from "aa" through "b" in its preferred stock rating system. The
modifier 1 indicates that the security ranks in the higher end of its generic
rating category; the modifier 2 indicates a mid-range ranking; and the modifier
3 indicates that the issue ranks in the lower end of its generic rating
category.

                  DESCRIPTION OF S&P'S PREFERRED STOCK RATINGS

AAA: This is the highest rating that may be assigned by S&P's to a preferred
stock issue and indicates an extremely strong capacity to pay the preferred
stock obligations. AA: A preferred stock issue rated AA also qualifies as a
high-quality fixed income security. The capacity to pay preferred stock
obligations is very strong, although not as overwhelming as for issues rated
AAA. A: An issue rated A is backed by a sound capacity to pay the preferred
stock obligations, although it is somewhat more susceptible to the adverse
effect of changes in circumstances and economic conditions. BBB: An issue rated
BBB is regarded as backed by an adequate capacity to pay the preferred stock
obligations. Whereas it normally exhibits adequate protection parameters,
adverse economic conditions or changing circumstances are more likely to lead to
a weakened capacity to make payments for a preferred stock in this category than
for issues in the A category. BB, B, CCC: Preferred stock rated BB, B, and CCC
are regarded, on balance, as predominantly speculative with respect to the
issuer's capacity to pay preferred stock obligations. BB indicates the lowest
degree of speculation and CCC the highest degree of speculation. While such
issues will likely have some quality and protective characteristics, these are
outweighed by large uncertainties or major risk exposures to adverse conditions.
CC: The rating CC is reserved for a preferred stock in arrears on dividends or
sinking fund payments but that is currently paying. C: A preferred stock rated C
is a non-

                                      B-29
<PAGE>   79


paying issue. D: A preferred stock rated D is a non-paying issue with the issuer
in default on debt instruments.

PLUS (+) OR MINUS (-): The ratings from "AA" to "B" may be modified by the
addition of a plus or minus sign to show relative standing within the major
rating categories.

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

     None



<PAGE>   83


ITEM 25.  INDEMNIFICATION

     Under Article VIII of the registrant's Articles of Incorporation and
Article V, Section 1 of the registrant's By-Laws, any past or present director
or officer of registrant is indemnified to the fullest extent permitted by law
against liability and all expenses reasonably incurred by him in connection with
any action, suit or proceeding to which he may be a party or otherwise involved
by reason of his being or having been a director or officer of registrant. These
provisions do not authorize indemnification when it is determined, in the manner
specified in the Articles of Incorporation and By-Laws, that such director or
officer would otherwise be liable to registrant or its shareholders by reason of
willful misfeasance, bad faith, gross negligence or reckless disregard of his
duties. In addition, the Articles of Incorporation provide that to the fullest
extent permitted by Maryland General Corporation Law, as amended from time to
time, no director or officer of the Fund shall be personally liable to the Fund
or its stockholders for money damages, except to the extent such exemption from
liability or limitation thereof is not permitted by the Investment Company Act
of 1940, as amended from time to time. Under Article V, Section 2, of the
registrant's By-Laws, expenses may be paid by registrant in advance of the final
disposition of any action, suit or proceeding upon receipt of an undertaking by
such director or officer to repay such expenses to registrant in the event that
it is ultimately determined that indemnification of the advanced expenses is not
authorized under the By-Laws.

     Insofar as indemnification for liability arising under the Securities Act
of 1933 (the "1933 Act") may be permitted to directors, officers and controlling
persons of 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
1933 Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by registrant
of expenses 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, 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 1933 Act and will be governed by the
final adjudication of such issue.

ITEM 26. BUSINESS AND OTHER CONNECTIONS OF INVESTMENT ADVISER

   
     Gabelli Funds, LLC is the investment adviser of the registrant (the
"Adviser"). For a list of officers and directors of the Adviser, together with
information as to any other business, profession, vocation or employment of a
substantial nature engaged in by the Adviser or such officers and directors
during the past two years, reference is made to Form ADV filed by it under the
Investment Advisers Act of 1940.
    

ITEM 27. PRINCIPAL UNDERWRITERS

     (a) Gabelli & Company, Inc. is registrant's proposed principal underwriter.

     (b) For information with respect to each director and officer of Gabelli &
         Company, Inc., reference is made to Form BD filed by Gabelli & Company,
         Inc. under the Securities Exchange Act of 1934.

     (c) Inapplicable.

ITEM 28. LOCATION OF ACCOUNTS AND RECORDS

         RE:      GABELLI INTERNATIONAL GROWTH FUND, INC.

Ladies and Gentlemen:

         You may rely on our attached opinion dated June 28, 1995 for purposes
of your proposed consent attached hereto with respect to Post-Effective
Amendment No. 7 to the Fund's Registration Statement pertaining to the Fund's
sole existing class of Common Stock on Form N-1A, Securities Act (File No.
33-79994), and Investment Company Act (File No. 811-8560) (the "Registration
Statement").

         For purposes of this letter, we have examined and relied upon a
certificate of the Maryland State Department of Assessments and Taxation to the
effect that the Fund is duly incorporated and existing under the laws of the
State of Maryland and is in good standing and duly authorized to transact
business in the State of Maryland. We have also examined and relied upon a
Certificate of the Assistant Secretary of the Fund, dated as of the date hereof,
with respect to such matters as we have deemed necessary to provide this letter.
Moreover, we have assumed for purposes of this letter that the terms and
consideration with respect to the issuance of shares of the Fund's Common Stock
as set forth in the Registration Statement remain the same as those set forth in
the Registration Statement at the time of our attached opinion in all material
respects.

         We consent to the filing of this letter as an exhibit to the
Registration Statement.

                                         Very truly yours,

         RE:      GABELLI INTERNATIONAL GROWTH FUND, INC.

Ladies and Gentlemen:

         We have acted as special Maryland counsel for Gabelli International
Growth Fund, Inc., a Maryland corporation (the "Fund"), in conneciton with the
organization of the Fund and the issuance of shares of its Common Stock, par
value $.001 per share (the "Common Stock").

         As Maryland counsel for the Fund, we are familiar with its Charter and
Bylaws. We have examined the prospectus included in its Registration Statement
on Form N-1A, Securities Act File No. 33-79994 and Investment Company Act File
No. 811-8560 (the "Registration Statement"), substantially in the form in which
it is to become effective (the "Prospectus"). We have further examined and
relied upon a certificate of the Maryland State Department of Assessments and
Taxation to the effect that the Fund is duly incorporated and existing under the
laws of the State of Maryland and is in good standing and duly authorized to
transact business in the State of Maryland.

         We have also examined and relied upon such corporate records of the
Fund and other documents and certificates with respect to factual matters as we
have deemed necessary to render the opinion expressed herein. We have assumed,
without independent verification, the genuineness of all signatures, the
authenticity of all documents submitted to us as originals, and the conformity
with originals of all documents submitted to us as copies.

         Based on such examination, we are of the opinion and so advise you 
that:

         1.       The Fund is duly organized and validly existing as a
                  corporation in good standing under the laws of the State of
                  Maryland.

         2.       The 10,000 presently issued and outstanding shares of Common
                  Stock of the Fund have been validly and legally issued and are
                  fully paid and nonassessable.

         3.       The shares of Common Stock of the Fund to be offered for sale
                  pursuant to the Prospectus are, to the extent of the number of
                  shares authorized to be issued by the Fund in its Articles of
                  Incorporation, duly authorized and, when sold, issued and paid
                  for as contemplated by the Prospectus, will have been validly
                  and legally issued and will be fully paid and nonassessable.

         This letter expresses our opinion with respect to the Maryland General
Corporation Law governing matters such as due organization and the authorization
and issuance of stock. It does not extend to the securities of "Blue Sky" laws
of Maryland, to federal securities laws or to other laws.

         You may rely upon our foregoing opinion in rendering your opinion to
the Fund that is to be filed as an exhibit to the Registration Statement. We
consent to the filing of this opinion as an exhibit to the Registration
Statement.

                                            Very truly yours,
