GOAL / APPROACH

      The Large-Cap Research Fund seeks growth of capital and growth of income
      consistent with reasonable risk. Normally, we invest in the undervalued
      common stocks of large- capitalization companies with outstanding equity
      securities having an aggregate market value of at least $1.5 billion.
      Current income is not emphasized. 

      In choosing stocks, we look for companies using the following process:

      o     Quantitative research is performed on a universe of large, seasoned
            U.S. companies to identify those whose stocks we believe represent
            the best bargains.

      o     Fundamental research is conducted to identify current bargain priced
            securities among the largest publicly traded companies. 

      Under normal circumstances, at least 65% of the Large-Cap Research Fund's
      total assets will consist of investments made in large companies,
      determined at the time of purchase. 

      Information on recent market conditions and the fund's strategies can be
      found under "Recent Performance" and in the current annual/semi-annual
      report (see back cover). The report also has the fund's holdings
      information.

MAIN RISKS

      The companies in which the fund invests will have good prospects for
      improvement in earnings trends or asset values. The fund will invest in
      companies on the basis of the fundamental economic and business factors
      which will affect future earnings and which the fund believes are the
      primary factors determining the future market valuation of stocks. There
      can be no assurance that stocks selected for our portfolio will appreciate
      in value or that their dividends will increase or be maintained.

      At the time of purchase, securities selected for our portfolio may be
      largely neglected by the investment community or, if widely followed, they
      may be out of favor or at least controversial. Our investment portfolio
      typically will encompass less market risk as measured by its
      price-to-normal-earnings and price-to-book-value ratios.
      Individual-security risk is managed through broad industry
      diversification. 

      The fund may invest up to 10% of net assets in foreign securities. Foreign
      securities markets may not be subject to the same degree of regulation as
      the U.S. markets and may be more volatile and less liquid than the major
      U.S. markets. Foreign investments are subject to currency exposure.
      Investors should also be aware that the fund has the ability to invest in
      derivatives. The 

      The fund may take a temporary defensive position by investing some of its
      assets in short-term debt securities. This could reduce the benefit from
      any upswing in the market.

We or the fund refers to the Lord Abbett Large-Cap Research Fund ("Large-Cap
Research Fund"), a separate portfolio of Lord Abbett Re-search Fund, Inc. (the
"company"). The fund operates under the supervision of the company's Board, with
the advice of Lord, Abbett & Co.("Lord Abbett"), its investment manager.

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

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

Large companies are established companies that are considered "known
quantities." Large companies often have the resources to weather economic
shifts, though they can be slower to innovate than small companies.

Seasoned companies are usually established companies whose securities have
gained a reputation for quality with the investing public and enjoy liquidity in
the market. 

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

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

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

Share class                   1 Year     3 Years    5 Years   10 Years

Class A shares                  $000        $000       $000       $000

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

Class A shares                  $000        $000       $000       $000

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

Past performance is not a prediction of future results.

- --------------------------------------------------------------------------------
(i)   The dates of inception for each class are: A - 6/3/92; B - 8/1/96; and C -
      4/1/97.
(ii)  Performance for the unmanaged S&P 500(R) Index does not reflect
      transaction costs or management fees.
(iii) This represents total returns for the period _________, provided to
      correspond with the class B and C inception dates.

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

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

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

- --------------------------------------------------------------------------------
(1)   The annual operating expenses have been restated from fiscal year amounts
      to reflect current fees.
(2)   5.00% if shares are redeemed before the 1st anniversary of purchase,
      declining to 1.00% before the 6th anniversary and eliminated on and after
      the 6th anniversary.
(3)   1.00% if shares are redeemed before 1st anniversary of purchase.
(4)   Because 12b-1 distribution fees (up to: 0.35%- class A; 0.75%- classes B
      and C; and 0.20% - class P) are paid out on an on-going basis, over time
      they will increase the cost of your investment and may cost you more than
      paying other types of sales charges. Service fees under each class's 12b-1
      Plan are up to 0.25%.
(5)   Class B shares will convert to class A shares on the eighth anniversary of
      your original purchase of class B shares.

GOAL / APPROACH

      The Growth Opportunities Fund seeks capital appreciation. Normally, we
      invest primarily in common stocks of middle-sized companies with
      outstanding equity securities having an aggregate market value between $1
      billion and $6 billion. The fund uses a growth style of investing which
      means that we favor companies that show the potential for stronger than
      expected earnings or growth. Under normal circumstances, at least 65% of
      our total assets will consist of investments made in growth companies, as
      determined at the time of purchase.

      In choosing stocks, we look for companies using the following process:

      o     Quantitative research is performed on a universe of middle-sized
            companies to identify those with superior growth possibilities.

      o     Fundamental research is performed to identify companies likely to
            produce superior returns over a thirty-six month time frame, by
            analyzing the dynamics in each company with its industry and within
            the economy.

      Before July 15, 1998, the fund used a value style of investing. This meant
      that companies were selected without regard to current earnings under a
      process that sought to identify and invest in undervalued securities.

      Information on recent market conditions and the fund's strategies can be
      found under "Recent Performance" and in the current annual/semi-annual
      report (see back cover). The report also has the fund's holdings
      information.

MAIN RISKS

      The value of your investment will fluctuate in response to stock market
      movements. In addition, growth stocks tend to be more volatile than
      slower-growing stocks. This means that the fund could be more volatile
      than the stock market as a whole.

      While typically fully invested, we may take a temporary defensive position
      by investing some of our assets in short-term debt securities. This could
      reduce the benefit from any upswing in the market.

We or the fund refers to the Lord Abbett Growth Opportunities Fund ("Growth
Opportunities Fund"), a separate portfolio of Lord Abbett Research Fund, Inc.
(the "com-pany"). The fund operates under the supervision of the company's Board
with the advice of Lord, Abbett & Co. ("Lord Abbett"), its investment manager.

government-endorsed. It is not a complete investment program. You could lose
money in this fund, but you also have the potential to make money. 

Growth stocks exhibit faster-than-average gains in earnings and are expected to
continue profit growth at a high-level. They tend to be more volatile than
slower-growing stocks.

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

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

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

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

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

GOAL / APPROACH

      The fund seeks long-term capital appreciation. Usually we invest primarily
      in equity securities of smaller companies with market capitalization
      between $100 million and $750 million.

      In choosing stocks we usually look for companies using the following
      process: 

      o     Quantitative research is performed to evaluate various criteria,
            including price/earnings, price/book value, price/cash flow and
            price/sales ratios. 

      o     Fundamental research is conducted to assess the dynamics of each
            company with its industry and within the economy, by evaluating the
            company's business strategies in assessing management's ability to
            execute the strategies and by evaluating the adequacy of a company's
            financial management. 

      Usually, at least 65% of the fund's total assets will be invested in
      common stocks issued by smaller, less well-known companies (with market
      capitalizations of less than $1 billion) selected using fundamental
      investment analysis. The fund may invest up to 35% of its total assets in
      the securities of larger companies. Companies in which the fund is likely
      to invest may have more limited product lines, markets or financial
      resources and may lack management depth or experience as compared with
      companies with larger market capitalizations.

      Information on recent market conditions and the fund's strategies can be
      found under "Recent Performance" and in the current annual/semi-annual
      report (see back cover). The report also has the fund's holdings
      information.

MAIN RISKS

      Small-company stocks offer significant appreciation potential. Generally,
      small- companies carry more risk than larger companies. Generally, small
      companies rely on limited product lines and markets, financial resources,
      or other factors, and this may make them more susceptible to setbacks or
      economic downturns. Small-company stocks tend to be more volatile in
      price, have fewer shares outstanding and trade less frequently than large
      company stocks. Therefore, small company stocks may be subject to wider
      price fluctuations. Many small-company stocks are traded over the counter
      and are not to be traded in the volume typical of stocks listed on a
      national securities exchange. 

      While typically fully invested, we may take a temporary defensive position
      by investing some of our assets in short-term debt securities. This could
      reduce the benefit from any upswing in the market.

We or the fund refers to Lord Abbett Small-Cap Value Fund ("Small-Cap Value
Fund"), a separate portfolio of the Lord Abbett Research Fund, Inc. (the
"company"). The fund operates under the supervision of the com pany's Board with
the advice of Lord, Abbett & Co. ("Lord Abbett"), its invest ment manager. The
fund is closed to new investors; only current shareholders may add to existing
accounts. 

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

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

Small companies often are new and less established, with a tendency to be
faster-growing but more volatile than large companies. 

Large companies are established companies that are considered "known
quantities." Large companies often have the resources to weather economic
shifts, though they can be slower to innovate than small companies.

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

PURCHASES

      This Prospectus offers four classes of shares, classes A, B ,C,and P for
      each the Large-Cap Research Fund, Growth Opportunities Fund and Small-Cap
      Value Fund. Although a fund may have more than one class of shares, these
      different classes of shares represent investments in the same portfolio of
      securities but are subject to different expenses. Our shares are
      continuously offered. The offering price is based on the Net Asset Value
      ("NAV") per share next determined after we accept your purchase order
      submitted in proper form. A front-end sales charge is added to the NAV, in
      the case of the class A shares. There is no front-end sales charge,
      although there is a CDSC in the case of the class B and C shares, as
      described below. 

      You should read this section carefully to determine which class of shares
      represents the best investment option for your particular situation. It
      may not be suitable for you to place a purchase order for class B shares
      of $500,000 or more or a purchase order for class C shares of $1,000,000
      or more. You should discuss pricing options with your investment
      professional. 

      For more information, see "Alternative Sales Arrangements" in the
      Statement of Additional Information.

      We reserve the right to withdraw all or any part of the offering made by
      this Prospectus or to reject any purchase order. We also reserve the right
      to waive or change minimum investment requirements. All purchase orders
      are subject to our acceptance and are not binding until confirmed or
      accepted in writing.

      o     Rights of Accumulation -- A purchaser can apply the value (at public

            class A shares of any Eligible Fund in order to reduce the sales
            charge.

NAV per share for each class of fund shares is calculated each business day at

they are being sold, which-ever is lower. In addition, repayment of loans under
Retirement Plans and 403(b) plans will constitute new sales for purposes of
assessing the CDSC.

      redeem your shares.

      By Telephone. To obtain the proceeds of a redemption of $50,000 or less

      which the account is registered, the fund's name, the class of shares,
      your account number, and the dollar value or number of shares you wish to

DISTRIBUTIONS AND TAXES

      Each fund pays its shareholders dividends from its net investment income,
      and distributes net capital gains that it has realized. Dividends from net
      investment income are expected to be paid to shareholders of Large-Cap
      Research Fund semi-annually, Growth Opportunities Fund annually, and
      Small-Cap Value Fund annually. If a capital gain distribution is declared,
      it will be paid annually. Your distributions will be reinvested in your
      fund unless you instruct the fund to pay them to you in cash. There are no
      sales charges on reinvestments. 

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

SALES CHARGES AND SERVICE FEES

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

      Sales compensation originates from two sources: sales charges and 12b-1
      distribution fees that are paid out of each fund's assets. Service
      compensation originates from 12b-1 service fees. The 12b-1 fee rates vary
      by share class, according to the Rule 12b-1 plan adopted by each fund. The
      sales charges and 12b-1 fees paid by investors are shown in the
      class-by-class information under "Expenses" and "Purchases." The portion
      of these expenses that is paid as sales and service compensation to
      Authorized Institutions, such as your dealer, is shown in the chart on the
      next page. The portion of such sales and service compensation paid to Lord
      Abbett Distributor is discussed under "Sales Activities" and "Service
      Activities" below. Sometimes we do not pay sales and service compensation
      where tracking data is not available for certain accounts or where the
      Authorized Institution waives part of the compensation. We may pay
      Additional Concessions to Authorized Institutions from time to time. Sales
      Activities. We may use 12b-1 distribution fees to pay Authorized
      Institutions to finance any activity which is primarily intended to result
      in the sale of shares. Lord Abbett Distributor uses its portion of the
      distribution fees attributable to a fund's class A and class C shares for
      activities which are primarily intended to result in the sale of such
      class A and class C shares, respectively. These activities include, but
      are not limited to, printing of prospectuses and statements of additional
      information and reports for other than exist ing shareholders, preparation
      and distribution of advertising and sales material, expenses of organizing
      and conducting sales seminars, Additional Concessions to Authorized Insti
      tu tions, the cost necessary to provide distribution-related services or
      personnel, travel, office expenses, equipment and other allocable
      overhead.

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

OTHER INVESTMENT TECHNIQUES

      Borrowing. Each fund may borrow from banks. If a fund borrows money, its
      share price may be subject to greater fluctuation until the borrowing is
      paid off. Each fund may borrow only for temporary or emergency purposes,
      and not in an amount exceeding 33 1/3% of its total assets. 

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

      Closed-End Investment Companies. Each fund may invest in shares of
      closed-end investment companies if it pays a fee or commission no greater
      than the customary broker's commission. Shares of investment companies
      sometimes trade at a discount or premium to their net asset value. Also,
      there may be duplication of fees if a fund and the closed-end investment
      company both charge a management fee. 

      Debt Securities. Debt securities or "junk bonds" are rated BB/Ba or lower
      and typically pay a higher yield than investment grade debt securities.
      These bonds have a higher risk of default than investment grade bonds and
      their prices can be much more volatile. The Small-Cap Value Fund will not
      invest more than 5% of its assets measured at the time of investment in
      high yield debt securities.

      Diversification. Each fund is a diversified fund, which means that with
      respect to 3/4 of its total assets, it will not purchase a security if, as
      a result, more than 5% of the fund's total assets would be invested in
      securities of a single issuer or the fund would hold more than 10% of the
      outstanding voting securities of the issuer.

      Financial Futures. A financial futures transaction is an exchange-traded
      contract to buy or sell a standard quality and quantity of a financial
      instrument or index at a specific future date and price. The price
      behavior of the futures contract may not correlate with that of the item
      being hedged.

<PAGE>

      A fund will not enter into any futures contracts, or options thereon, if
      the aggregate market value of the securities covered by futures contracts
      plus options on such financial futures exceeds 50% of its total assets.

      Foreign Currency Hedging Techniques. Although the funds do not normally
      engage in extensive currency hedging, they may use currency forwards and
      options to hedge the risk to the portfolio if they expect that foreign
      exchange price movements will be unfavorable for U.S. investors.
      Generally, these instruments allow a fund to lock in a specified exchange
      rate for a period of time. If the fund's forecast proves to be wrong, such
      a hedge may cause a loss. Also, it may be difficult or impractical to
      hedge currency risk in many emerging countries. The funds generally will
      not enter into a forward contract with a term greater than one year. Under
      some circumstances, a fund may commit a substantial portion or the entire
      value of its portfolio to the completion of forward contracts. Although
      such contracts will be used primarily to protect the fund from adverse
      currency movements, their use involves the risk Lord Abbett will not
      accurately predict currency movement, and the fund's return could be
      reduced.

      Foreign Securities. These securities are not subject to the same degree of
      regulation and may be more volatile and less liquid than securities traded
      in major U.S. markets. This affects block trading. Foreign portfolio
      securities may trade on days when a fund does not value them. Fund share
      prices could be affected on days an investor cannot purchase or sell
      shares. Other risks include less information on public companies, banks
      and governments; political and social instability; expropriations; higher
      transaction costs; currency fluctuations; nondeductable withholding taxes
      and different accounting and settlement practices.

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

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

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

<PAGE>

      Portfolio Securities Lending. Each fund may lend securities to
      broker-dealers and financial institutions, as a means of earning income.
      This practice could result in a loss or delay in recovering a fund's
      securities, if the borrower defaults. Each fund will limit its securities
      loans to 33 1/3% of its total assets.

      Repurchase Agreements. In a Repurchase Agreement, a fund buys a security
      at one price from a broker-dealer or financial institution and
      simultaneously agrees to sell the same security back to the same party at
      a higher price in the future. If the other party to the agreement defaults
      or becomes insolvent, a fund could lose money.

      When-Issued or Delayed Delivery Securities. Each fund may purchase or sell
      securities with payment and delivery taking place as much as a month or
      more later. A fund would do this in an effort to buy or sell the
      securities at an advantageous price and Yield. The securities involved are
      subject to market fluctuation and no interest accrues to the purchaser
      during the period between purchase and settlement. At the time of delivery
      of the securities, their market value may be less than the purchase price.
      Also, if a fund commits a significant amount of assets to when-issued or
      delayed delivery transactions, it may increase the volatility of the
      fund's net asset value.

GLOSSARY OF SHADED TERMS

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

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

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

      Eligible Fund. An Eligible Fund is any Lord Abbett-sponsored fund except
      for: (1) certain tax-free, single-state funds where the exchanging
      shareholder is a resident of a state in which such fund is not offered for
      sale; (2)

      Lord Abbett Equity Fund; (3) Lord Abbett Series Fund; and (4) Lord Abbett
      U.S. Government Securities Money Market Fund ("GSMMF") (except for
      holdings in GSMMF which are attributable to any shares exchanged from the
      Lord Abbett family of funds). An Eligible Fund also is any Authorized
      Institution's affiliated money market fund satisfying Lord Abbett
      Distributor as to certain omnibus account and other criteria.

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

      Legal Capacity. This term refers to the authority of an individual to act
      on behalf of an entity or other person(s). For example, if a redemption
      request were to be made on behalf of the estate of a deceased shareholder,
      John W. Doe, by a person (Robert A. Doe) who has the legal capacity to act
      for the estate of the deceased shareholder because he is the executor of
      the estate, then the request must be executed as follows: Robert A. Doe,
      Executor of the Estate of John W. Doe. That signature using that capacity
      must be guaranteed by an Eligible Guarantor.

      To give another example, if a redemption request were to be made on behalf
      of the ABC Corporation by a person (Mary B. Doe) who has the legal
      capacity to act on the behalf of the Corporation, because she is the
      president of the Corporation, the request must be executed as follows: ABC
      Corporation by Mary B. Doe, President. That signature using that capacity
      must be guaranteed by an Eligible Guarantor.

      Mutual Fund Advisory Program. This includes certain unaffiliated
      authorized brokers, dealers, registered investment advisers or other
      financial institutions who either (a) have an arrangement with Lord Abbett
      Distributor in accordance with certain standards approved by Lord Abbett
      Distributor, providing specifically for the use of fund shares (and
      sometimes providing for acceptance of orders for such shares on Lord
      Abbett Distributor's behalf) in particular investment products made
      available for a fee to clients of such brokers, dealers, registered
      investment advisers and other financial institutions or (b) who charge an
      advisory, consulting or other fee for their services and buy shares for
      their own accounts or the accounts of their clients. 

      Purchaser. The term "purchaser" includes: (i) an individual; (ii) an
      individual and his or her spouse and children under the age of 21; and
      (iii) a trustee or other fiduciary purchasing shares for a single trust
      estate or single fiduciary account (including a pension, profit-sharing,
      or other employee benefit trust qualified under Section 401 of the
      Internal Revenue Code - more than one qualified employee benefit trust of
      a single employer, including its consolidated subsidiaries, may be
      considered a single trust, as may qualified plans of multiple employers
      registered in the name of a single bank trustee as one account), although
      more than one beneficiary is involved. Special Retirement Wrap Program.
      This is a program sponsored by an Authorized Institution showing one or
      more characteristics distinguishing it, in the opinion of Lord Abbett
      Distributor, from a Mutual Fund Wrap-Fee Program. Such characteristics
      include, among other things, the fact that an Authorized Institution does
      not charge its clients any fee of a consulting or advisory nature that is
      economically equivalent to the distribution fee under the class A 12b-1
      Plan and the fact that the program relates to participant-directed
      Retirement Plans.

RECENT PERFORMANCE

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

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

Euro. On January 1, 1999, the eleven member states of the European Union
converted to a common currency, know as the "Euro." Each fund could be adversely
affected if the computers used by it and its service providers do not properly
process and calculate Euro-related information from and after January 1, 1999.

(1)   The service fee for class A and P shares is paid quarterly and for class A
      shares may not exceed 0.15% for shares sold prior to June 1, 1990. The
      first year's service fee on class B and C shares is paid at the time of
      sale. 
(2)   Reallowance/concession percentages and service fee percentages are
      calculated from different amounts, and therefore may not equal total
      compensation percentages if combined using simple addition. Additional
      Concessions may be paid to Authorized Institutions, such as your dealer,
      from time to time.
(3)   Concessions are paid at the time of sale on all class A shares sold during
      any 12-month period starting from the day of the first net asset value
      sale. With respect to (a) class A share purchases at $1 million or more,
      sales qualifying at such level under rights of accumulation and statement
      of intention privileges are included and (b) for Special Retirement Wrap
      Programs, only new sales are eligible and exchanges into the fund are
      excluded.
(4)   With respect to class B, C and P shares, 0.25%, 1.00% and 0.45%,
      respectively, of the average annual net asset value of such shares
      outstanding during the quarter (including distribution reinvestment shares
      after the first anniversary of their issuance) is paid to Authorized
      Institutions, such as your dealer. These fees are paid quarterly in
      arrears.

LORD ABBETT

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

                             Large-Cap Research Fund
                            Growth Opportunities Fund
                              Small-Cap Value Fund

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

Lord Abbett Research Fund, Inc. (the "Company") was incorporated in Maryland on
April 6, 1992. The Company has three funds, Large-Cap Research Fund, Growth
Opportunities Fund, and Small-Cap Value Fund, which are described in this
Statement of Additional Information. The Large-Cap Research Fund has four
classes of shares (A, B, C, and P), and Growth Opportunities Fund and Small-Cap
Value Fund each have five (A, B, C, P and Y). Only classes A, B, C, and P are
offered by this Statement of Additional Information. All classes of shares have
equal noncumulative voting rights and equal rights with respect to dividends,
assets and liquidation, except for certain class-specific expenses. They are
fully paid and nonassessable when issued and have no preemptive or conversion
rights.

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

                               Investment Policies

Fundamental Investment Restrictions. Each Fund is subject to the following
fundamental investment restrictions which cannot be changed without the approval
of the holders of a majority of a Fund's respective shares. If a Fund determines
that its objectives can best be achieved by a change in any non-fundamental
investment policy, strategy or restriction, it may make such change without
shareholder approval by disclosing it in the Prospectus or Statement of
Additional Information.

Each Fund may not: (1) borrow money, except that (i) each Fund may borrow from
banks (as defined in the Investment Company Act of 1940, as amended (the "Act"))
in amounts up to 33 1/3% of its total assets (including the amount borrowed),
(ii) each Fund may borrow up to an additional 5% of its total assets for
temporary purposes, (iii) each Fund may obtain such short-term credit as may be
necessary for the clearance of purchases and sales of portfolio securities and
(iv) each Fund may purchase securities on margin to the extent permitted by
applicable law; (2) pledge its assets (other than to secure borrowings, or to
the extent permitted by the Funds' investment policies as permitted by
applicable law); (3) engage in the underwriting of securities, except pursuant
to a merger or acquisition or to the extent that, in connection with the
disposition of its portfolio securities, it may be deemed to be an underwriter
under federal securities laws; (4) make loans to other persons, except that the
acquisition of bonds, debentures or other corporate debt securities and
investment in government obligations, commercial paper, pass-through
instruments, certificates of deposit, bankers acceptances, repurchase agreements
or any similar instruments shall not be subject to this limitation, and except
further that each Fund may lend its portfolio securities, provided that the
lending of portfolio securities may be made only in accordance with applicable
law; (5) buy or sell real estate (except that each Fund may invest in securities
directly or indirectly secured by real estate or interests therein or issued by
companies which invest in real estate or interests therein) or commodities or
commodity contracts (except to the extent each Fund may do so in accordance with
applicable law and without registering as a commodity pool operator under the
Commodity Exchange Act as, for example, with futures contracts); (6) with
respect to 75% of the gross assets of each Fund, buy securities of one issuer
representing more than (i) 5% of each Fund's gross assets, except securities
issued or guaranteed by the U.S. Government, its agencies or instrumentalities
or (ii) own more than 10% of the voting securities of such issuer; (7) invest
more than 25% of its assets, taken at market value, in the securities of issuers
in any particular industry (excluding securities of the U.S. Government, its
agencies and instrumentalities); or (8) issue senior securities to the extent
such issuance would violate applicable law.

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

Non-Fundamental Investment Restrictions. In addition to policies in the
Prospectus and the investment restrictions above which cannot be changed without
shareholder approval, each fund is also subject to the following non-fundamental
investment policies which may be changed by the Board of Directors without
shareholder approval. Each Fund may not: (1) borrow in excess of 33 1/3% of its
total assets (including the amount borrowed), and then only as a temporary
measure for extraordinary or emergency purposes; (2) make short sales of
securities or maintain a short position except to the extent permitted by
applicable law; (3) invest knowingly more than 15% of its net assets (at the
time of investment) in illiquid securities, except for securities qualifying for
resale under Rule 144A of the Securities Act of 1933 ("Rule 144A"), deemed to be
liquid by the Board of Directors; (4) invest in the securities of other
investment companies as defined in the Act, except as permitted by applicable
law; (5) invest in securities of issuers which, with their predecessors, have a
record of less than three years' continuous operation, if more than 5% of each
Fund's total assets would be invested in such securities (this restriction shall
not apply to mortgaged-backed securities, asset-backed securities or obligations
issued or guaranteed by the U. S. Government, its agencies or
instrumentalities); (6) hold securities of any issuer if more than 1/2 of 1% of
the securities of such issuer are owned beneficially by one or more of the
officers or directors of the Funds or by one or more partners or members of the
Funds' underwriter or investment adviser if these owners in the aggregate own
beneficially more than 5% of the securities of such issuer; (7) invest in
warrants if, at the time of the acquisition, its investment in warrants, valued
at the lower of cost or market, would exceed 5% of each Fund's total assets
(included within such limitation, but not to exceed 2% of each Fund's total
assets, are warrants which are not listed on the New York or American Stock
Exchange or a foreign exchange); (8) invest in real


                                       2
<PAGE>

estate limited partnership interests or interests in oil, gas or other mineral
leases, or exploration or development programs, except that each Fund may invest
in securities issued by companies that engage in oil, gas or other mineral
exploration or development activities; (9) write, purchase or sell puts, calls,
straddles, spreads or combinations thereof, except to the extent permitted in
the Funds' prospectuses and statements of additional information, as they may be
amended from time to time; or (10) buy from or sell to any of the Funds'
officers, directors, employees, or its investment adviser or any of the Funds'
officers, directors, partners or employees, any securities other than shares of
the Funds' common stock.

For the fiscal year ended November 30, 1998, the portfolio turnover rate was   %
for the Large-Cap Research Fund compared to 30.81% for the previous year;   %
for Growth Opportunities Fund compared to for the previous year, and   % for
Small-Cap Value Fund compared to 45.24% for the previous year.

INVESTMENT TECHNIQUES

ALL FUNDS

Lending Of Portfolio Securities. Although each Fund has no current intention of
doing so, each may seek to earn income by lending portfolio securities. Under
present regulatory policies, such loans may be made to member firms of the New
York Stock Exchange ("NYSE") and are required to be secured continuously by
collateral consisting of cash, cash equivalents, or United States Treasury bills
maintained in an amount at least equal to the market value of the securities
loaned. Each Fund will have the right to call a loan and obtain the securities
loaned at any time upon five days' notice. During the existence of a loan we
will receive the income earned on investment of collateral. The aggregate value
of the securities loaned will not exceed 5% of the value of a Fund's gross
assets.

LARGE-CAP RESEARCH FUND And GROWTH OPPORTUNITIES FUND (ONLY) 

Covered Call Options. A Fund may write covered call options on securities in our
portfolio in an attempt to increase income and provide greater flexibility in
the disposition of portfolio securities. A "call option" is a contract sold for
a price (the "premium") giving its holder the right to buy a specific number of
shares of a stock at a specific price prior to a specified date. A "covered call
option" is a call option issued on securities already owned by the writer of the
call option for delivery to the holder upon the exercise of the option. During
the period of the option, a Fund forgoes the opportunity to profit from any
increase in the market price of the underlying security above the exercise price
of the option (to the extent that the increase exceeds our net premium). A Fund
also may enter into "closing purchase transactions" in order to terminate an
obligation to deliver the underlying security (this may result in a short-term
gain or loss). A closing purchase transaction is the purchase of a call option
(at a cost which may be more or less than the premium received for writing the
original call option) on the same security with the same exercise price and call
period as the option previously written. If a Fund is unable to enter into a
closing purchase transaction, it may be required to hold a security that it
otherwise might have sold to protect against depreciation. A Fund does not
intend to write covered call options with respect to securities with an
aggregate market value of more than 5% of a Fund's gross assets at the time an
option is written. This percentage limitation will not be increased without
prior disclosure in a Funds' current prospectus.

Rights And Warrants. A Fund may invest in rights and warrants to purchase
securities. Included within that amount, but not to exceed 2% of the value of
Large-Cap Research Fund's net assets and 5% of the value of Growth Opportunities
Fund's gross assets, may be warrants which are not listed on the NYSE or
American Stock Exchange.

Rights represent a privilege offered to holders of record of issued securities
to subscribe (usually on a pro rata basis) for additional securities of the same
class, of a different class or of a different issuer, as the case may be.
Warrants represent the privilege to purchase securities at a stipulated price
and are usually valid for several years. Rights and warrants generally do not
entitle a holder to dividends or voting rights with respect to the underlying
securities nor do they represent any rights in the assets of the issuing
company.

Also, the value of a right or warrant may not necessarily change with the value
of the underlying securities and rights and warrants cease to have value if they
are not exercised prior to their expiration date.

Options And Financial Futures Transactions. A Fund may engage in options and
financial futures transactions in accordance with their investment objective and
policies. Although each Fund is not currently employing such options and
financial futures transactions, they may engage in such transactions in the
future if it appears advantageous to us to do so, in order to cushion the
effects of fluctuating interest rates and adverse market conditions. The use of
options and financial futures, and possible benefits and attendant risks, are
discussed below, along with information concerning certain other investment
policies and techniques.

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

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

There may be an imperfect correlation between movements in prices of futures
contracts and portfolio securities being hedged. The degree of difference in
price movements between futures contracts and the securities (or securities
indices) being hedged depends upon such things as variations in demand for
futures contracts and securities underlying the contracts and differences
between the liquidity of the markets for such contracts and the securities
underlying them. In addition, the market prices of futures contracts may be
affected by certain factors not directly related to the underlying securities.
At any given time, the availability of futures contracts, and hence their
prices, are influenced by credit conditions and margin requirements. Due to the
possibility of price distortions in the futures market and because of the
imperfect correlation between movements in the prices of securities and
movements in the prices of futures contracts, a correct forecast of market
trends by the investment adviser may not result in a successful hedging
transaction.

Options On Financial Futures Contracts. A Fund may purchase and write call and
put options on financial futures contracts. An option on a futures contract
gives the purchaser the right, in return for the premium paid, to assume a
position in a futures contract at a specified exercise price at any time during
the period of the option. Upon exercise, the writer of the option delivers the
futures contract to the holder at the exercise price. A Fund would be required
to deposit with the custodian initial margin and maintenance margin with respect
to put and call options on futures contracts written by a Fund. Options on
futures contracts involve risks similar to the risks relating to transactions in
financial futures contracts described above. Generally speaking, a given dollar
amount used to purchase an option on a financial futures contract can hedge a
much greater value of underlying securities than if that amount were used to
directly purchase the same financial futures. Should the event it intends to
hedge (or protect) against not materialize, however, the option may expire
worthless, in which case a Fund would lose the premium paid therefor.

Segregated Accounts. To the extent required to comply with Securities and
Exchange Commission Release 10666 and subsequent interpretation thereof by the
Commission or its staff, when purchasing a futures contract, or writing a put
option, each Fund will maintain in a segregated account at the custodian bank in
liquid high grade debt obligations, such as cash and U.S. Government Securities
to cover its position.

SMALL-CAP VALUE FUND And GROWTH OPPORTUNITIES FUND (ONLY)

Repurchase Agreements. If a Fund enter into repurchase agreements as provided in
clause (4) of the fundamental investment restrictions above, it will do so only
with those primary reporting dealers that report to the Federal Reserve Bank of
New York and with the 100 largest United States commercial banks and the
underlying securities purchased under the agreements will consist only of those
securities in which the a Fund otherwise may invest.

Foreign Currency Hedging Techniques. A Fund may utilize various foreign currency
hedging techniques described below, including forward foreign currency contracts
and foreign currency put and call options.

Forward Foreign Currency Contracts. A forward foreign currency contract involves
an obligation to purchase or sell a specific amount of a specific currency at a
set price at a future date. A Fund expects to enter into forward foreign
currency contracts in primarily two circumstances. First, when a Fund enters
into a contract for the purchase or sale of a security denominated in a foreign
currency, it may desire to "lock in" the U.S. dollar price of the security. By
entering into a forward contract for the purchase or sale of the amount of
foreign currency involved in the underlying security transaction, a Fund will be
able to protect against a possible loss resulting from an adverse change in the
relationship between the U.S. dollar and the subject foreign currency during the
period between the date the security is purchased or sold and the date on which
payment is made or received.

Second, when management believes that the currency of a particular foreign
country may suffer a decline against the U.S. dollar, a Fund may enter into a
forward contract to sell the amount of foreign currency approximating the value
of some or all of a Fund's portfolio securities denominated in such foreign
currency or, in the alternative, a Fund may use a cross-hedging technique
whereby it sells another currency which a Fund expects to decline in a similar
way but which has a lower transaction cost. Precise matching of the forward
contract amount and the value of the securities involved will not generally be
possible since the future value of such securities denominated in foreign
currencies will change as a consequence of market movements in the value of
those securities between the date the forward contract is entered into and the
date it matures. A Fund does not intend to enter into such forward contracts
under this second circumstance on a continuous basis.

Foreign Currency Put And Call Options. A Fund also may purchase foreign currency
put options and write foreign currency call options on U.S. exchanges or U.S.
over-the-counter markets. A put option gives a Fund, upon payment of a premium,
the right to sell a currency at the exercise price until the expiration of the
option and serves to insure against adverse currency price movements in the
underlying portfolio assets denominated in that currency.

Exchange-listed options markets in the United States include several major
currencies, and trading may be thin and illiquid. A number of major investment
firms trade unlisted options which are more flexible than exchange-listed
options with respect to strike price and maturity date. Unlisted options
generally are available in a wider range of currencies. Unlisted foreign
currency options are generally less liquid than listed options and involve the
credit risk associated with the individual issuer. Unlisted options, together
with other illiquid securities, are subject to a limit of 15% of a Fund's net
assets.

A call option written by a Fund gives the purchaser, upon payment of a premium,
the right to purchase from a Fund a currency at the exercise price until the
expiration of the option. A Fund may write a call option on a foreign currency
only in conjunction with a purchase of a put option on that currency. Such a
strategy is designed to reduce the cost of downside currency protection by
limiting currency appreciation potential. The face value of such writing may not
exceed 90% of the value of the securities denominated in such currency invested
in by a Fund or in such cross currency (referred to above) to cover such call
writing.

Each Fund's custodian will segregate cash or permitted securities belonging to
the Fund in an amount not less than that required by SEC Release 10666 and
related policies with respect to the Fund's assets committed to (a) writing
options, (b) forward foreign currency contracts and (c) cross hedges entered
into by the Fund. If the value of the securities segregated declines, additional
cash or debt securities will be added on a daily basis (i.e., marked to market),
so that the segregated amount will not be less than the amount of the Fund's
commitments with respect to such written options, forward foreign currency
contracts and cross hedges.

SMALL-CAP VALUE FUND (ONLY)

Limitations On The Purchases And Sales Of Stock Options, Options On Stock
Indices And Stock Index Futures. The Small-Cap Value Fund may write put and call
options on stocks only if they are covered, and such options must remain covered
so long as the Small-Cap Value Fund is obligated as a writer. The Fund will not
(a) write puts having an aggregate exercise price greater than 25% of the
Series' total net assets; or (b) purchase (i) put options on stocks not held in
the Fund's portfolio, (ii) put options on stock indices or (iii) call options on
stocks or stock indices if, after any such purchase, the aggregate premiums paid
for such options would exceed 20% of the Fund's total net assets.

Call Options On Stock. The Small-Cap Value Fund may, from time to time, write
call options on its portfolio securities. The Small-Cap Value Fund may write
only call options which are "covered," meaning that the Fund either owns the
underlying security or has an absolute and immediate right to acquire that
security, without additional cash consideration, upon conversion or exchange of
other securities currently held in its portfolio. In addition, the Fund will not
permit the call to become uncovered prior to the expiration of the option or
termination through a closing purchase transaction as described below. If the
Fund writes a call option, the purchaser of the option has the right to buy (and
the Fund has the obligation to sell) the underlying security at the exercise
price throughout the term of the option. The amount paid to the Fund by the
purchaser of the option is the "premium." The Small-Cap Value Fund's obligation
to deliver the underlying security against payment of the exercise price would
terminate either upon expiration of the option or earlier if the Small-Cap Value
Fund were to effect a "closing purchase transaction" through the purchase of an
equivalent option on an exchange. There can be no assurance that a closing
purchase transaction can be effected. The Small-Cap Value Fund does not intend
to write covered call options with respect to securities with an aggregate
market value of more than 5% of it's gross assets at the time an option is
written. This percentage limitation will not be increased without prior
disclosure in our current prospectus.

The Small-Cap Value Fund would not be able to effect a closing purchase
transaction after it had received notice of exercise. In order to write a call
option, the Small-Cap Value Fund is required to comply with the rules of The
Options Clearing Corporation and the various exchanges with respect to
collateral requirements. The Fund may not purchase call options except in
connection with a closing purchase transaction. It is possible that the cost of
effecting a closing purchase transaction may be greater than the premium
received by the Small-Cap Value Fund for writing the option.

Generally, the Small-Cap Value Fund intends to write listed covered call options
during periods when it anticipates declines in the market values of portfolio
securities because the premiums received may offset to some extent the decline


                                       6
<PAGE>

in the Fund's net asset value occasioned by such declines in market value.
Except as part of the "sell discipline" described below, the Fund will generally
not write listed covered call options when it anticipates that the market values
of it's portfolio securities will increase.

One reason for the Fund to write call options is as part of a "sell discipline."
If the Small-Cap Value Fund decides that a portfolio security would be
overvalued and should be sold at a certain price higher than the current price,
it could write an option on the stock at the higher price. Should the stock
subsequently reach that price and the option be exercised, the Fund would, in
effect, have increased the selling price of that stock, which it would have sold
at that price in any event, by the amount of the premium. In the event the
market price of the stock declined and the option were not exercised, the
premium would offset all or some portion of the decline. It is possible that the
price of the stock could increase beyond the exercise price; in that event, the
Small-Cap Value Fund would forego the opportunity to sell the stock at that
higher price.

In addition, call options may be used as part of a different strategy in
connection with sales of portfolio securities. If, in the judgment of the Fund
Management, the market price of a stock is overvalued and it should be sold, the
Fund may elect to write a call option with an exercise price substantially below
the current market price. As long as the value of the underlying security
remains above the exercise price during the term of the option, the option will,
in all probability, be exercised, in which case the Small-Cap Value Fund will be
required to sell the stock at the exercise price. If the sum of the premium and
the exercise price exceeds the market price of the stock at the time the call
option is written, the Fund would, in effect, have increased the selling price
of the stock. The Fund would not write a call option in these circumstances if
the sum of the premium and the exercise price were less than the current market
price of the stock.

Put Options On Stock. The Small-Cap Value Fund may also write listed put
options. If the Fund writes a put option, it is obligated to purchase a given
security at a specified price at any time during the term of the option.

Writing listed put options is a useful portfolio investment strategy when the
Small-Cap Value Fund has cash or other reserves available for investment as a
result of sales of Fund shares or, more importantly, because Fund Management
believes a more defensive and less fully invested position is desirable in light
of market conditions. If the Fund Management wishes to invest its cash or
reserves in a particular security at a price lower than current market value, it
may write a put option on that security at an exercise price which reflects the
lower price it is willing to pay. The buyer of the put option generally will not
exercise the option unless the market price of the underlying security declines
to a price near or below the exercise price. If the Small-Cap Value Fund writes
a listed put, the price of the underlying stock declines and the option is
exercised, the premium, net of transaction charges, will reduce the purchase
price paid by the Small-Cap Value Fund for the stock. The price of the stock may
decline by an amount in excess of the premium, in which event the Small-Cap
Value Fund would have foregone an opportunity to purchase the stock at a lower
price.

If, prior to the exercise of a put option, the Fund determines that it no longer
wishes to invest in the stock on which the put option had been written, the Fund
may be able to effect a closing purchase transaction on an exchange by
purchasing a put option of the same series as the one which it has previously
written. The cost of effecting a closing purchase transaction may be greater
than the premium received on writing the put option and there is no guarantee
that a closing purchase transaction can be effected.

Stock Index Options. Except as describe below, the Small-Cap Value Fund will
write call options on indices only if on such date it holds a portfolio of
stocks at least equal to the value of the index times the multiplier times the
number of contracts. When the Small-Cap Value Fund writes a call option on a
broadly-based stock market index, the Fund will segregate or put into escrow
with its custodian, or pledge to a broker as collateral for the option, one or
more "qualified securities" with a market value at the time the option is
written of not less than 100% of the current index value times the multiplier
times the number of contracts.

Segregated Accounts. If the Small-Cap Value Fund has written an option on an
industry or market segment index, it will segregate or put into escrow with its
custodian, or pledge to a broker as collateral for the option, at least ten
"qualified securities," which are securities of an issuer in such industry or
market segment, with a market value at the


                                       7
<PAGE>

time the option is written of not less than 100% of the current index value
times the multiplier times the number of contracts. A "qualified security" is an
equity security which is listed on a national securities exchange or listed on
the National Association of Securities Dealers Automated Quotation System
against which the Small-Cap Value Fund has not written a stock call option and
which has not been hedged by the Small-Cap Value Fund by the sale of stock index
futures. Such securities will include stocks which represent at least 50% of the
weighing of the industry or market segment index and will represent at least 50%
of the Small-Cap Value Fund's holdings in that industry or market segment. No
individual security will represent more than 25% of the amount so segregated,
pledged or escrowed. If at the close of business on any day the market value of
such qualified securities so segregated, escrowed or pledged falls below 100% of
the current index value times the multiplier times the number of contracts, the
Small-Cap Value Fund will so segregate, escrow or pledge an amount in cash,
Treasury bills or other high-grade short-term obligations equal in value to the
difference. In addition, when the Small-Cap Value Fund writes a call on an index
which is in-the-money at the time the call is written, it will segregate with
its custodian or pledge to the broker as collateral cash, equity securities,
non-investment grade debt, short term U.S. Government securities or other
high-grade short-term debt obligations equal in value to the amount by which the
call is in-the-money times the multiplier times the number of contracts. Any
amount segregated pursuant to the foregoing sentence may be applied to the
Small-Cap Value Fund's obligation to segregate additional amounts in the event
that the market value of the qualified securities falls below 100% of the
current index value times the multiplier times the number of contracts. However,
if the Small-Cap Value Fund holds a call on the same index as the call written
where the exercise price of the call held is equal to or less than the exercise
price of the call written or greater than the exercise price of the call written
if the difference is maintained by the Small-Cap Value Fund in cash, equity
securities, non-investment grade debt, treasury bills or other high-grade
short-term obligations in a segregated account with its custodian, it will not
be subject to the requirements describe in this paragraph. In instances
involving the purchase of stock index futures contracts by the Small-Cap Value
Fund, an amount of cash or permitted securities equal to the market value of the
futures contracts will be deposited in a segregated account with its custodian
and/or in a margin account with a broker to collateralize the position and
thereby insure that the use of such futures are unleveraged.

Under regulations of the Commodity Exchange Act, investment companies registered
under the Act are exempt from the definition of "commodity pool operator,"
provided all of the Small-Cap Value Fund's commodity futures or commodity
options transactions constitute bona fide hedging transactions within the
meaning of the CFTC's regulations. The Small-Cap Value Fund will use stock index
futures and options on futures as described herein in a manner consistent with
this requirement.

Stock Index Futures. The Small-Cap Value Fund will engage in transactions in
stock index futures contracts as a hedge against changes resulting from market
conditions in the values of securities which are held in the Small-Cap Value
Fund's portfolio or which it intends to purchase. The Fund will engage in such
transactions when they are economically appropriate for the reduction of risks
inherent in the ongoing management of the Fund. The Fund may not purchase or
sell stock index futures if, immediately thereafter, more than one-third of its
net assets would be hedged and, in addition, except as described above in the
case of a call written and held on the same index, will write call options on
indices or sell stock index futures only if the amount resulting from the
multiplication of the then current level of the index (or indices) upon which
the option or future contract(s) is based, the applicable multiplier(s), and the
number of futures or options contracts which would be outstanding, would not
exceed one-third of the value of the Small-Cap Value Fund's net assets.

Risks Of Transactions In Stock Options. Writing options involves the risk that
there will be no market in which to effect a closing transaction. An option
position may be closed out only on an exchange which provides a secondary market
for an option of the same series. Although the Small-Cap Value Fund will
generally write only those options for which there appears to be an active
secondary market, there is no assurance that a liquid secondary market on an
exchange will exist for any particular option, or at any particular time, and
for some options no secondary market on an exchange may exist. If the Small-Cap
Value Fund, as a covered call option writer, is unable to effect a closing
purchase transaction in a secondary market, it will not be able to sell the
underlying security until the option expires or it delivers the underlying
security upon exercise.

Risks Of Options On Indices. The Small-Cap Value Fund's purchase and sale of
options on indices will be subject to risks described above under "Risk of
Transactions in Stock Options." In addition, the distinctive characteristics of
options on indices create certain risks that are not present with stock options.

Because the value of an index option depends upon movements in the level of the
index rather than the price of a particular stock, whether the Small-Cap Value
Fund will realize a gain or loss on the purchase or sale of an option on an
index depends upon movements in the level of stock prices in the stock market
generally or in an industry or market segment rather than movements in the price
of a particular stock. Accordingly, successful use by the Small-Cap Value Fund
of options on indices would be subject to the investment adviser's ability to
predict correctly movements in the direction of the stock market generally or of
a particular industry. This requires different skills and techniques than
predicting changes in the price of individual stocks.

Index prices may be distorted if trading of certain stocks included in the index
is interrupted. Trading in the index option also may be interrupted in certain
circumstances, such as if trading were halted in a substantial number of stocks
included in the index. If this occurred, the Small-Cap Value Fund would not be
able to close out options which it had purchased or written and, if restrictions
on exercise were imposed, may be unable to exercise an option it holds, which
could result in substantial losses to the Small-Cap Value Fund. It is the
Small-Cap Value Fund's policy to purchase or write options only on indices which
include a number of stocks sufficient to minimize the likelihood of a trading
halt in the index.

Trading in index options commenced in April 1983 with the S&P 100 option
(formerly called the CBOE 100). Since that time a number of additional index
option contracts have been introduced including options on industry indices.
Although the markets for certain index option contracts have developed rapidly,
the markets for other index options are still relatively illiquid. The ability
to establish and close out positions on such options will be subject to the
development and maintenance of a liquid secondary market. It is not certain that
this market will develop in all index option contracts. The Small-Cap Value Fund
will not purchase or sell any index option contract unless and until, in Fund
management's opinion, the market for such options has developed sufficiently
that such risk in connection with such transactions in no greater than such risk
in connection with options on stocks.

Special Risks Of Writing Calls On Indices. Because exercises of index options
are settled in cash, a call writer cannot determine the amount of its settlement
obligations in advance and, unlike call writing on specific stocks, cannot
provide in advance for, or cover, its potential settlement obligations by
acquiring and holding the underlying securities. However, the Small-Cap Value
Fund will write call options on indices only under the circumstances described
above under "Limitations on the Purchases and Sales of Stock Options, Options on
Stock Indices and Stock Index Futures."

Price movements in the Fund's portfolio probably will not correlate precisely
with movements in the level of the index and, therefore, the Fund bears the risk
that the price of the securities held may not increase as much as the index. In
such event the Fund would bear a loss on the call which is not completely offset
by movements in the price of the Fund's portfolio. It is also possible that the
index may rise when the Small-Cap Value Fund's portfolio of stocks does not
rise. If this occurred, the Fund would experience a loss on the call which is
not offset by an increase in the value of its portfolio and might also
experience a loss in its portfolio. However, because the value of a diversified
portfolio will, over time, tend to move in the same direction as the market,
movements in the value of the Small-Cap Value Fund in the opposite direction to
the market would be likely to occur for only a short period or to a small
degree.

Unless the Small-Cap Value Fund has other liquid assets that are sufficient to
satisfy the exercise of a call, the Small-Cap Value Fund would be required to
liquidate portfolio securities in order to satisfy the exercise. Because an
exercise must be settled within hours after receiving the notice of exercise, if
the Small-Cap Value Fund fails to anticipate an exercise, it may have to borrow
(in amounts not exceeding 20% of the Fund's total assets) pending settlement of
the sale of securities in its portfolio and would incur interest charges
thereon.

When the Small-Cap Value Fund has written a call, there is also a risk that the
market may decline between the time the call is written and the time the
Small-Cap Value Fund is able to sell stocks in its portfolio. As with stock
options, the Small-Cap Value Fund will not learn that an index option has been
exercised until the day following the exercise date


                                       9
<PAGE>

but, unlike a call on stock where the Small-Cap Value Fund would be able to
deliver the underlying securities in settlement, the Fund may have to sell part
of its stock portfolio in order to make settlement in cash, and the price of
such stocks might decline before they can be sold. This timing risk makes
certain strategies involving more than one option substantially more risky with
index options than with stock options. For example, even if an index call which
the Small-Cap Value Fund has written is "covered" by an index call held by the
Small-Cap Value Fund with the same strike price, the Small-Cap Value Fund will
bear the risk that the level of the index may decline between the close of
trading on the date the exercise notice is filed with the clearing corporation
and the close of trading on the date the Small-Cap Value Fund exercises the call
it holds or the time the Small-Cap Value Fund sells the call which in either
case would occur no earlier than the day following the day the exercise notice
was filed.

Special Risks Of Purchasing Puts And Calls On Indices. If the Small-Cap Value
Fund holds an index option and exercises it before final determination of the
closing index value for that day, it runs the risk that the level of the
underlying index may change before closing. If such a change causes the
exercised option to fall out-of-the-money, the Fund will be required to pay the
difference between the closing index value and the exercise price of the option
(times the applicable multiple) to the assigned writer. Although the Small-Cap
Value Fund may be able to minimize this risk by withholding exercise
instructions until just before the daily cut off time or by selling rather than
exercising an option when the index level is close to the exercise price it may
not be possible to eliminate this risk entirely because the cut off times for
index options may be earlier than those fixed for other types of options and may
occur before definitive closing index values are announced.

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

2.    The amounts in Column 3 were accrued by the Lord Abbett-sponsored
      companies for the 12 months ended November 30, 1998 with respect to the
      equity based plans established for independent directors in 1996. This
      plan supercedes a previously approved retirement plan for all future
      directors. Current directors had the option to convert their accrued
      benefits under the retirement plan. All of the outside directors except
      one made such an election.

3.    This column shows aggregate compensation, including directors fees and
      attendance fees for board and committee meetings, of a nature referred to
      in footnote one, accrued by the Lord Abbett-sponsored companies during the
      year ended December 31, 1998. The amounts of the aggregate compensation
      payable by the Company as of November 30, 1998 deemed invested in Company
      shares, including dividends reinvested and changes in net asset value
      applicable to such deemed investments, were: Mr. Bigelow, $     ; Mr.
      Dixon, $     ; Mr. Jansing, $     ; Mr. MacDonald, $     ; Mr. Millican,
      $     ; and Mr. Neff, $     . If the amounts deemed invested in Company
      shares were added to each director's actual holdings of Company shares as
      of November 30, 1998, each would own, the following: Mr. Bigelow,
          shares; Mr. Dixon,     shares; Mr. Jansing,     shares; Mr. MacDonald,
          shares; Mr. Millican,     shares; and Mr. Neff,     shares.

4.    Mr. Jansing chose to continue to receive benefits under the retirement
      plan which provides that outside directors (Trustees) may receive annual
      retirement benefits for life equal to their final annual retainer
      following retirement at


                                       12
<PAGE>

      or after age 72 with at least ten years of service. Thus, if Mr. Jansing
      were to retire and the annual retainer payable by the funds were the same
      as it is today, he would receive annual retirement benefits of $50,000.

Except where indicated, the following executive officers of the Company have
been associated with Lord Abbett for over five years. Of the following, Messrs.
Brown, Carper, Fetch, Hilstad, Morris, and Walsh are partners of Lord Abbett;

Large-Cap Research Fund.

For the fiscal years ended November 30, 1996, 1997 the management fee was .75 of
1% and was waived by Lord Abbett with respect to the Growth Opportunities Fund
and, except for this waiver, would have amounted to $8,249 and $10,844,

                                       4.
                             Portfolio Transactions

The Funds' policy is to obtain best execution on all our portfolio transactions,
which means that they seek to have purchases and sales of portfolio securities
executed at the most favorable prices, considering all costs of the transaction
including brokerage commissions and dealer markups and markdowns and taking into
account the full range and quality of the brokers' services. Consistent with
obtaining best execution, we generally pay, as described below, a higher


                                       14
<PAGE>

commission than some brokers might charge on the same transaction. Our policy
with respect to best execution governs the selection of brokers or dealers and
the market in which the transaction is executed. To the extent permitted by law,
we may, if considered advantageous, make a purchase from or sale to another Lord
Abbett-sponsored fund without the intervention of any broker-dealer.

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

We pay a commission rate that we believe is appropriate to give maximum
assurance that our brokers will provide us, on a continuing basis, the highest
level of brokerage services available. While we do not always seek the lowest
possible commissions on particular trades, we believe that our commission rates
are in line with the rates that many other institutions pay. Our traders are
authorized to pay brokerage commissions in excess of those that other brokers
might accept on the same transactions in recognition of the value of the
services performed by the executing brokers, viewed in terms of either the
particular transaction or the overall responsibilities of Lord Abbett with
respect to us and the other accounts they manage. Such services include showing
us trading opportunities including blocks, a willingness and ability to take
positions in securities, knowledge of a particular security or market proven
ability to handle a particular type of trade, confidential treatment, promptness
and reliability.

Some of these brokers also provide research services at least some of which are
useful to Lord Abbett in their overall responsibilities with respect to us and
the other accounts they manage. Research includes the furnishing of analyses and
reports concerning issuers, industries, securities, economic factors and trends,
portfolio strategy and the performance of accounts and trading equipment and
computer software packages, acquired from third-party suppliers, that enable
Lord Abbett to access various information bases. Such services may be used by
Lord Abbett in servicing all their accounts, and not all of such services will
necessarily be used by Lord Abbett in connection with their management of the
Fund; conversely, such services furnished in connection with brokerage on other
accounts managed by Lord Abbett may be used in connection with their management
of the Fund, and not all of such services will necessarily be used by Lord
Abbett in connection with their advisory services to such other accounts. We
have been advised by Lord Abbett that research services received from brokers
cannot be allocated to any particular account, are not a substitute for Lord
Abbett's services but are supplemental to their own research effort and, when
utilized, are subject to internal analysis before being incorporated by Lord
Abbett into their investment process. As a practical matter, it would not be
possible for Lord Abbett to generate all of the information presently provided
by brokers. While receipt of research services from brokerage firms has not
reduced Lord Abbett's normal research activities, the expenses of Lord Abbett
could be materially increased if it attempted to generate such additional
information through its own staff and purchased such equipment and software
packages directly from the suppliers.

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

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

If other clients of Lord Abbett buy or sell the same security at the same time
as a Lord Abbett-sponsored fund does, transactions will, to the extent
practicable, be allocated among all participating accounts in proportion to the
amount of each order and will be executed daily until filled so that each
account shares the average price and commission cost of each day. Other clients
who direct that their brokerage business be placed with specific brokers or who
invest through wrap accounts introduced to Lord Abbett by certain brokers may
not participate with a Lord Abbett-sponsored fund in the buying and selling of

as a Lord Abbett-sponsored fund does, they may have their transactions executed
at times different from our transactions and thus may not receive the same price
or incur the same commission cost as a Lord Abbett-sponsored fund does.

The Lord Abbett-sponsored funds will not seek "reciprocal" dealer business (for
the purpose of applying commissions in whole or in part for their benefit or
otherwise) from dealers as consideration for the direction to them of portfolio
business.

For the fiscal years ended November 30, 1996, 1997 and 1998, we paid total
commissions to independent broker-dealers of $28,649, $88,234 and $    for
Large-Cap Research Fund, respectively.

For the fiscal years ended November 30, 1996, 1997, and 1998, we paid total
commissions to independent broker-dealers of $2,155, $3,687 and $     ,
respectively, for Growth Opportunities Fund.

For the period December 13, 1995 (commencement of operations) to November 30,
1996 and fiscal years ended November 30, 1997 and 1998, we paid total
commissions to independent broker-dealers of $45,266, $1,812,425, and $     for
Small-Cap Value Fund.

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

As disclosed in the Prospectus, we calculate our net asset value as of the close
of the New York Stock Exchange ("NYSE") on each day that the NYSE is open for
trading by dividing our total net assets by the number of shares outstanding at
the time of calculation. The NYSE is closed on Saturdays and Sundays and the
following holidays -- New Year's Day, Martin Luther King, Jr. Day, Presidents'
Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving and
Christmas.

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

The net asset value per share for the Class B and C shares will be determined in
the same manner as for the Class A shares (net assets divided by shares
outstanding).

The maximum offering price of Class A shares of the Large-Cap Research Fund on
November 30, 1998 was computed as follows:

Net asset value per share (net assets divided
by shares outstanding)  . . . . . . . . . . . . . . . . . . . . . . . . .$

Maximum offering price per share (net asset
value divided by .9425) . . . . . . . . . . . . . . . . . . . . . . . . .$

The Company on behalf of the funds has entered into a distribution agreement
with Lord Abbett Distributor LLC, a New York limited liability company ("Lord
Abbett Distributor"), under which Lord Abbett Distributor is obligated to use
its best efforts to find purchasers for the shares of the Funds, and to make
reasonable efforts to sell the shares so long as, in Lord Abbett Distributor's
judgment, a substantial distribution can be obtained by reasonable efforts.

For the last three fiscal years Lord Abbett, as the Funds' principal
underwriter, received net commissions after allowance of a portion of the sales
charge to independent dealers with respect to Class A shares as follows:

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

Classes of Shares. The Funds offer investors four different classes of shares,
designated Classes A, B, C and P. The different classes of shares represent
investments in the same portfolio of securities but are subject to different
expenses and will likely have different share prices. Investors should read this
section carefully to determine which class represents the best investment option
for their particular situation.

Class A Shares. If you buy Class A shares, you pay an initial sales charge on
investments of less than $1 million (or on investments for employer-sponsored
retirement plans under the Internal Revenue Code (hereinafter referred to as
"Retirement Plans") with less than 100 eligible employees or on investments that
do not qualify to be under a "special retirement wrap program" as a program
sponsored by an authorized institution showing one or more characteristics
distinguishing it, in the opinion of Lord Abbett Distributor from a mutual fund
wrap-fee program). If you purchase Class A shares as part of an investment of at
least $1 million (or for Retirement Plans with at least 100 eligible employees
or under a special retirement wrap program) in shares of one or more Lord
Abbett-sponsored funds, you will not pay an initial sales charge, but if you
redeem any of those shares within 24 months after the month in which you buy
them, you may pay to a Fund a contingent deferred sales charge ("CDSC") of 1%
except for redemptions under a special retirement wrap program. Class A shares
of the Large-Cap Research Fund are subject to service and distribution fees that
are currently estimated to total annually approximately .23 of 1% of the annual
net asset value of the Class A shares. Class A shares of the Growth
Opportunities Fund are subject to service and distribution fees that are
currently estimated to total annually approximately 0.28 of 1% of the annual net
asset value of the Class A shares. Class A shares of the Small-Cap Value Fund
are subject to service and distribution fees that are currently estimated to
total annually approximately .31 of 1% of the annual net asset value of the
Class A shares. The initial sales charge rates, the CDSC and the Rule 12b-1 plan
applicable to the Class A shares are described in "Buying Class A Shares."

Class B Shares. If you buy Class B shares, you pay no sales charge at the time
of purchase, but if you redeem your shares before the sixth anniversary of
buying them, you will normally pay a CDSC to Lord Abbett Distributor . That CDSC
varies depending on how long you own your shares. Class B shares are subject to
service and distribution fees at an annual rate of 1% of the annual net asset
value of the Class B shares. The CDSC and the Rule 12b-1 plan applicable to the
Class B shares are described in "Buying Class B Shares."

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

Class P Shares. If you buy Class P shares, you pay no sales charge at the time
of purchase, and if you redeem your shares you pay no CDSC. Class P shares are
subject to service and distribution fees at an annual rate of .45 of 1% of the
average daily net asset value of the Class P shares. The Rule 12b-1 plan
applicable to the Class P shares is described in "Class P Rule 12b-1 Plan."
Class P shares are available to a limited number of investors.

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

In the following discussion, to help provide you and your financial adviser with
a framework in which to choose a class, we have made some assumptions using a
hypothetical investment in the Funds. We used the sales charge rates that apply
to Class A, Class B and Class C, and considered the effect of the higher
distribution fees on Class B and Class C expenses (which will affect your
investment return). Of course, the actual performance of your investment


                                       18
<PAGE>

cannot be predicted and will vary, based on a Fund's actual investment returns,
the operating expenses borne by each class of shares, and the class of shares
you purchase. The factors briefly discussed below are not intended to be
investment advice, guidelines or recommendations, because each investor's
financial considerations are different. The discussion below of the factors to
consider in purchasing a particular class of shares assumes that you will
purchase only one class of shares and not a combination of shares of different
classes.

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

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

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

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

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

Of course, these examples are based on approximations of the effect of current
sales charges and expenses on a hypothetical investment over time, and should
not be relied on as rigid guidelines.

Are There Differences In Account Features That Matter To You? Some account
features are available in whole or in part to Class A, Class B and Class C
shareholders. Other features (such as Systematic Withdrawal Plans) might not be
advisable in non-Retirement Plan accounts for Class B shareholders (because of
the effect of the CDSC on the entire amount of a withdrawal if it exceeds 12%
annually) and in any account for Class C shareholders during the


                                       19
<PAGE>

first year of share ownership (due to the CDSC on withdrawals during that year).
See "Systematic Withdrawal Plan" under "Shareholder Services" in the Prospectus
for more information about the 12% annual waiver of the CDSC. You should
carefully review how you plan to use your investment account before deciding
which class of shares you buy. For example, the dividends payable to Class B and
Class C shareholders will be reduced by the expenses borne solely by each of
these classes, such as the higher distribution fee to which Class B and Class C
shares are subject, as described below.

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

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

The fees payable under the A Plan, B Plan, C Plan, and P Plan are described in
the Prospectus. For the fiscal year ended November 30, 1998, the fees paid to
dealers under the A Plan for the Large-Cap Research Fund was $     , for the
Growth Opportunities Fund $     , and for the Small-Cap Value Fund $     .

For the fiscal year ended November 30, 1998, the fee paid to dealers under the B
Plan for the Large-Cap Research Fund was $     , for the Growth Opportunities
Fund $     , and for the Small-Cap Value Fund $     .

For the fiscal year ended November 30, 1998, the fee paid to dealers under the C
Plan for the Large-Cap Research Fund was $     , for the Growth Opportunities
Fund $     , and for the Small-Cap Value Fund $     .

Each Plan requires the directors to review, on a quarterly basis, written
reports of all amounts expended pursuant to the Plan and the purposes for which
such expenditures were made. Each Plan shall continue in effect only if its
continuance is specifically approved at least annually by vote of the directors,
including a majority of the directors who are not interested persons of the Fund
and who have no direct or indirect financial interest in the operation of the
Plan or in any agreements related to the Plan ("outside directors"), cast in
person at a meeting called for the purpose of voting on the Plan. No Plan may be
amended to increase materially above the limits set forth therein the amount
spent for distribution expenses thereunder without approval by a majority of the
outstanding voting securities of the applicable Class and the approval of a
majority of the directors, including a majority of the outside directors. Each
Plan may be terminated at any time by vote of a majority of the outside
directors or by vote of a majority of its Class's outstanding voting securities.

Contingent Deferred Sales Charges. A Contingent Deferred Sales Charge ("CDSC")
applies upon early redemption of shares, regardless of class, and : (i) will be
assessed on the lesser of the net asset value of the shares at the time of


                                       20
<PAGE>

redemption or the original purchase price and (ii) will not be imposed on the
amount of your account value represented by the increase in net asset value over
the initial purchase price (including increases due to the reinvestment of
dividends and capital gains distributions) and upon early redemption of shares.

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

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

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

The amount of the CDSC charge will depend on the number of years since you
invested and the dollar amount being redeemed, according to the following
schedule:
                                            Contingent Deferred Sales Charge
Anniversary of the Day on                    on Redemptions (As % of Amount 
Which the Purchase Order Was Accepted              Subject to Charge)       
Before the 1st ........................................   5.0%
On the 1st, before the 2nd ............................   4.0%
On the 2nd, before the 3rd ............................   3.0%
On the 3rd, before the 4th ............................   3.0%
On the 4th, before the 5th ............................   2.0%
On the 5th, before the 6th ............................   1.0%
On or after the 6th anniversary .......................   None

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

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

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

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


                                       21
<PAGE>

its expenses of providing distribution-related service to the Fund (including
recoupment of the commission payments made) in connection with the sale of Class
B shares before Lord Abbett Distributor has had an opportunity to realize its
anticipated reimbursement by having such a long-term shareholder account subject
to the B Plan distribution fee.

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

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

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

Shareholders in other Lord Abbett-sponsored funds and AMMF have the same right
to exchange their shares for the corresponding class of each Series' shares.
Exchanges are based on relative net asset values on the day instructions are
received by the Fund in Kansas City if the instructions are received prior to
the close of the NYSE in proper form. No sales charges are imposed except in the
case of exchanges out of GSMMF or AMMF (unless a sales charge (front-end,
back-end or level) was paid on the initial investment in a Lord Abbett-sponsored
fund). Exercise of the exchange privilege will be treated as a sale for federal
income tax purposes, and, depending on the circumstances, a gain or loss


                                       22
<PAGE>

may be recognized. In the case of an exchange of shares that have been held for
90 days or less where no sales charge is payable on the exchange, the original
sales charge incurred with respect to the exchanged shares will be taken into
account in determining gain or loss on the exchange only to the extent such
charge exceeds the sales charge that would have been payable on the acquired
shares had they been acquired for cash rather than by exchange. The portion of
the original sales charge not so taken into account will increase the basis of
the acquired shares.

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

Statement of Intention. Under the terms of the Statement of Intention to invest
$50,000 or more over a 13-month period as described in the Prospectus, shares of
a Lord Abbett-sponsored fund (other than shares of LAEF, LASF, LARF, GSMMF and
AMMF, unless holdings in GSMMF and AMMF are attributable to shares exchanged
from a Lord Abbett-sponsored fund offered with a front-end, back-end or level
sales charge) currently owned by you are credited as purchases (at their current
offering prices on the date the Statement is signed) toward achieving the stated
investment and reduced initial sales charge for Class A shares. Class A shares
valued at 5% of the amount of intended purchases are escrowed and may be
redeemed to cover the additional sales charge payable if the Statement is not
completed. The Statement of Intention is neither a binding obligation on you to
buy, nor on a Fund to sell, the full amount indicated.

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

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

Our Class A shares also may be purchased at net asset value: (a) at $1 million
or more; (b) with dividends and distributions from Class A shares of other Lord
Abbett-sponsored funds, except for LARF, LAEF and LASF; (c) under the loan
feature of the Lord Abbett-sponsored prototype 403(b) plan for share purchases
representing the repayment of principal and interest; (d) by certain authorized
brokers, dealers, registered investment advisers or other financial institutions
who have entered into an agreement with Lord Abbett Distributor in accordance
with certain standards approved by Lord Abbett Distributor, providing
specifically for the use of our shares in particular investment products made
available for a fee to clients of such brokers, dealers, registered investment
advisers and other financial institutions, ("mutual fund wrap fee program"); (e)
by employees, partners and owners of unaffiliated consultants and advisors to
Lord Abbett, Lord Abbett Distributor or Lord Abbett-sponsored funds who consent
to such purchase if such persons provide service to Lord Abbett, Lord Abbett
Distributor or such funds on a continuing basis and are familiar with such
funds; (f) through Retirement Plans with at least 100 eligible employees; (g) in
connection with a merger, acquisition or other reorganization; and (h) through a
"special retirement wrap program" sponsored by an authorized institution showing
one or more characteristics distinguishing it, in the opinion of Lord Abbett
Distributor from a mutual fund wrap-


                                       23
<PAGE>

fee program. Such characteristics include, among other things, the fact that an
authorized institution does not charge its clients any fee of a consulting or
advisory nature that is economically equivalent to the distribution fee under
Class A 12b-1 Plan and the fact that the program relates to a
participant-directed Retirement Plan. Shares are offered at net asset value to
these investors for the purpose of promoting goodwill with employees and others
with whom Lord Abbett Distributor and/or the Funds have business relationships.

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

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

Our Board of Directors may authorize redemption of all of the shares in any
account in which there are fewer than 25 shares. Before authorizing such
redemption, the Board must determine that it is in our economic best interest or
is necessary to reduce disproportionately burdensome expenses in servicing
shareholder accounts. At least 6 month's prior written notice will be given
before any such redemption, during which time shareholders may avoid redemption
by bringing their accounts up to the minimum set by the Board.

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

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

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

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

                                Past Performance

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

In calculating total returns for Class A shares, the current maximum sales
charge of 5.75% (as a percentage of the offering price) is deducted from the
initial investment (unless the return is shown at net asset value). For Class B
shares, the payment of the applicable CDSC (5.0% prior to the first anniversary
of purchase, 4.0% prior to the second anniversary of purchase, 3.0% prior to the
third and fourth anniversaries of purchase, 2.0% prior to the fifth anniversary
of purchase, 1.0% prior to the sixth anniversary of purchase and no CDSC on and
after the sixth anniversary of purchase) is applied to a Fund's investment
result for that class for the time period shown (unless the total return is
shown at net asset value). For Class C shares, the 1.0% CDSC is applied to a
Fund's investment result for that class for the time period shown prior to the
first anniversary of purchase (unless the total return is shown at net asset
value). Total returns also assume that all dividends and capital gains
distributions during the period are reinvested at net asset value per share, and
that the investment is redeemed at the end of the period. Total returns also
assume that all dividends and capital gains distributions during the period are
reinvested at net asset value per share, and that the investment is redeemed at
the end of the period.

Using the method to compute average annual compounded total return described
above, for the Class A shares of the Large-Cap Research Fund for each of the
fiscal years ended November 30, 1996, 1997, and 1998, assuming a $1,000
investment at the beginning of the period, the average annual rates of total
return were    %,    % and    % and the redeemable values amounted to $     ,
$     and $     , respectively. With respect to Class A shares of the Small-Cap
Value Fund for the fiscal years ended November 30, 1996, 1997, and 1998,
assuming a $1,000 investment at the beginning of the period, the average annual
rate of total return was    %,    %, and    %, and the redeemable value amounted
to $     , $     and $     , respectively.

Our yield quotation for each class is based on a 30-day period ended on a
specified date, computed by dividing the net investment income per share earned
during the period by the maximum offering price per share of such class on the
last day of the period. This is determined by finding the following quotient:
take the dividends and interest earned during the period for a class minus its
expenses accrued for the period and divide by the product of : (i) the average
daily number of Class shares outstanding during the period that were entitled to
receive dividends; and (ii) the maximum offering price per share of such class
on the last day of the period. To this quotient add one. This sum is multiplied
by itself five times. Then one is subtracted from the product of this
multiplication and the remainder is multiplied by two. Yield for the Class A
shares reflects the deduction of the maximum initial sales charge, but may also
be shown based on the Class A net asset value per share. Yields for Class B and
C shares do not reflect the deduction of the CDSC.

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

                                       7.
                                      Taxes

The value of any shares redeemed by the Funds or repurchased or otherwise sold
may be more or less than your tax basis in the shares at the time of
disposition. Any gain will generally be taxable for United States federal income
tax purposes. Any loss realized on the disposition of fund shares which you have
held for six months or less will be treated for tax purposes as a long-term
capital loss to the extent of any "capital gains distributions" which you
received with respect to


                                       25
<PAGE>

such shares. Losses on the sale of shares are not deductible if, within a period
beginning 30 days before the date of the sale and ending 30 days after the date
of the sale, the taxpayer acquires shares that are substantially identical.

The writing of call options and other investment techniques and practices which
a Fund may utilize may affect the character and timing of the recognition of
gains and losses. Such transactions may increase the amount of short-term
capital gain realized by a Fund, which is taxed as ordinary income when
distributed to shareholders. Limitations imposed by the Internal Revenue Code on
regulated investment companies may restrict a Fund's ability to engage in
transactions in options.

The Funds may be subject to foreign withholding taxes which would reduce the
yield on their investments. It is expected that fund shareholders who are
subject to United States federal income tax will be entitled to claim a federal
income tax credit or deduction for foreign income taxes paid by the Fund.

The Funds will be subject to a 4% non-deductible excise tax on certain amounts
not distributed or treated as having been distributed on a timely basis each
calendar year. The Funds intend to distribute to shareholders each year an
amount adequate to avoid the imposition of such excise tax.

Dividends paid by the Funds will qualify for the dividends-received deduction
for corporations to the extent they are derived from dividends paid by domestic
corporations.

Gain and loss realized by the Funds on certain transactions, including sales of
foreign debt securities and certain transactions involving foreign currency,
will be treated as ordinary income or loss for federal income tax purposes to
the extent, if any, that such gain or loss is attributable to changes in
exchange rates for foreign currencies. Accordingly, distributions taxable as
ordinary income will include the net amount, if any, of such foreign exchange
gains and will be reduced by the net amount, if any, of such foreign exchange
losses.

If the Funds purchase shares in certain foreign investment entities called
"passive foreign investment companies," they may be subject to United States
federal income tax on a portion of any "excess distribution" or gain from the
disposition of such shares, even if such income is distributed as a taxable
dividend by the Funds to shareholders. Additional charges in the nature of
interest may be imposed on either the Funds' or their shareholders in respect of
deferred taxes arising from such distributions or gains. If the Funds were to
make a "qualified electing fund" election with respect to investment in a
passive foreign investment company, in lieu of the foregoing requirements, the
Funds might be required to include in income each year a portion of the ordinary
earnings and net capital gains of the qualified electing fund, even if such
amount were not distributed to the Funds.

The foregoing discussion relates solely to U.S. federal income tax law as
applicable to United States persons (United States citizens or residents and
United States domestic corporations, partnerships, trusts and estates.) Each
shareholder who is not a United States person should consult his tax adviser
regarding the U.S. and foreign tax consequences of the ownership of shares of
the Funds, including a 30% (or lower treaty rate) United States withholding tax
on dividends representing ordinary income and net short-term capital gains, and
the applicability of United States gift and estate taxes.

                                       26
<PAGE>

The directors, trustees and officers of Lord Abbett-sponsored mutual funds,
together with the partners and employees of Lord Abbett, are permitted to
purchase and sell securities for their personal investment accounts. In engaging
in personal securities transactions, however, such persons are subject to
requirements and restrictions contained in the Fund's Code of Ethics which
complies, in substance, with each of the recommendations of the Investment
Company Institute's Advisory Group on Personal Investing. Among other things,
the Code requires that Lord Abbett partners and employees obtain advance
approval before buying or selling securities, submit confirmations and quarterly
transaction reports, and obtain approval before becoming a director of any
company; and it prohibits such persons from investing in a security 7 days
before or after any Lord Abbett-sponsored fund or Lord Abbett-managed account
considers a trade or trades in such security, prohibiting profiting on trades of
the same security within 60 days and trading on material and non-public
information. The Code imposes certain similar requirements and restrictions on
the independent directors and trustees of each Lord Abbett-sponsored mutual fund
to the extent contemplated by the recommendations of such Advisory Group.

Item 25     Indemnification


                                       2
<PAGE>

            All Trustees, officers, employees and agents of Registrant are to be
            indemnified as set forth in Section 4.3 of Registrant's Declaration
            of Trust.

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

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

                         LORD ABBETT RESEARCH FUND, INC.

                                    ARTICLE I

Directors may from time to time determine. 

                                   ARTICLE II

                              STOCKHOLDERS MEETING

      Section 1. Annual Meetings. The Corporation shall not hold an annual
meeting of its stockholders in any fiscal year of the Corporation unless
required in accordance with the following sentence. The Chairman of the Board or
the President shall call an annual meeting of the stockholders when the election
of directors is required to be acted on by stockholders under the Investment
Company Act of 1940, as amended, and the Chairman of the Board, the President, a
Vice President, the Secretary or any director shall call an annual meeting of
stockholders at the request in writing of a majority of the Board of Directors

<PAGE>

held pursuant to the foregoing sentence shall be held at such time and at such
place, within the City of New York or elsewhere, as may be fixed by the Chairman
of the Board or the President or the Board of Directors or by the stockholders
holding at least one-quarter of the stock of the Corporation outstanding and
entitled to vote, as the case may be, and as may be stated in the notice setting
forth such call, provided that any stockholders requesting such meeting shall
have paid to the Corporation the reasonably estimated cost of preparing and
mailing the notice thereof, which the Secretary shall determine and specify to
such stockholders. Any meeting of stockholders held in accordance with this
Section 1 shall for all purposes constitute the annual meeting of stockholders
for the fiscal year of the Corporation in which the meeting is held and, without
limiting the generality of the foregoing, shall be held for the purposes of (a)
acting on any such matter or matters so required to be acted on by stockholders
under the Investment Company Act of 1940, as amended, and (b) electing
directors, and for transacting such other business as may properly be brought
before the meeting. Only such business, in addition to that prescribed by law,
by the Articles of Incorporation and by these By-laws, may be brought before
such meeting as may be specified by resolution of the Board of Directors or by
writing filed with the Secretary of the Corporation and signed by the Chairman
of the Board or by the President or by a majority of the directors


                                       2
<PAGE>

or by stockholders holding at least one-quarter of the stock of the Corporation
outstanding and entitled to vote at the meeting.

      Section 2. Special Meetings. Special meetings of the stockholders for any
purpose or purposes may be held upon call by the Chairman of the Board or by a
majority of the Board of Directors, and shall be called by the Chairman of the
Board, the President, a Vice President, the Secretary or any director at the
request in writing of a majority of the Board of Directors or of stockholders
holding at least one-quarter of the stock of the Corporation outstanding and
entitled to vote at the meeting, at such time and at such place where an annual
meeting of stockholders could be held, as may be fixed by the Chairman of the
Board, the President or the Board of Directors or by the stockholders holding at
least one-quarter of the stock of the Corporation outstanding and so entitled to
vote, as the case may be, and as may be stated in the notice setting forth such
call. Such request shall state the purpose or purposes of the proposed meeting,
and only such purpose or purposes so specified may properly be brought before
such meeting.

        Section 3. Notice of Meetings. Written or printed notice of every annual
or special meeting of stockholders, stating the time and place thereof and the
general nature of the business proposed to be transacted at any such meeting,
shall be delivered personally or mailed not less than 10 or more than 90 days
previous thereto to each stockholder of record entitled to vote at the meeting
at his address as the same appears on


                                       3
<PAGE>

the books of the Corporation. Meetings may be held without notice if all of the
stockholders entitled to vote are present or represented at the meeting, or if
notice is waived in writing, either before or after the meeting, by those not
present or represented at the meeting. No notice of an adjourned meeting of the
stockholders other than an announcement of the time and place thereof at the
preceding meeting shall be required.

      Section 4. Quorum. The presence in person or by proxy of the holders of a
third of the Shares of all Classes issued and outstanding and entitled to vote
thereat shall constitute a quorum for the transaction of any business at all
meetings of the shareholders except as otherwise provided by law or in the
Articles of Incorporation and except that where the holders of the Shares of any
Class are entitled to a separate vote as a Class (a "Separate Class") or where
the holders of Shares of two or more (but not all) Classes are required to vote
as a single Class (a "Combined Class"), the presence in person or by proxy of
the holders of a third of the Shares of that Separate Class or Combined Class,
as the case may be, issued and outstanding and entitled to vote thereat shall
constitute a quorum for such vote. If, however, a quorum with respect to all
Classes, a Separate Class or a Combined Class, as the case may be, issued and
outstanding and entitled to vote thereat shall constitute a quorum for such
vote. If, however, a quorum with respect to all Classes, a Separate Class or a
Combined Class, as the case may be, shall not be present or represented at any
meeting of the shareholders, the holders of a majority of the Shares of 


                                       4
<PAGE>

all Classes, such Separate Class or such Combined Class, as the case may be,
present in person or by proxy and entitled to vote shall have power to adjourn
the meeting from time to time as to all Classes, such Separate Class or such
Combined Class, as the case may be without notice other than announcement at the
meeting, until the requisite number of Shares entitled to vote at such meeting
shall be present. At such adjourned meeting at which the requisite number of
Shares entitled to vote thereat shall be represented any business may be
transacted at the meeting as originally notified. The absence from any meeting
of stockholders of the number of Shares in excess of a third of the Shares of
all Classes or of the affected Class or Classes, as the case may be, which may
be required by laws of the State of Maryland, the Investment Company Act of 1940
or any other applicable law or the Articles of Incorporation, for action upon
any given matter shall not prevent action of such meeting upon any other matter
or matters which may properly come before the meeting, if there shall be present
thereat, in person or by proxy, holders of the number of Shares required for
action in respect of such matter or matters. 

      Section 5. Voting. All elections shall be had and all questions decided by
a majority of the votes cast, without regard to Class, at a duly constituted
meeting, except as otherwise provided by law or by the Articles of Incorporation
or by these By-laws and except that with respect to a question as to which the
holders of Shares of any Class or Classes are entitled or required to vote as a
Separate Class or a Combined Class, as the 


                                       5
<PAGE>

case may be, such question shall be decided as to such Separate Class or such
Combined Class, as the case may be, by a majority of the votes cast by Shares of
such Separate Class or such Combined Class, as the case may be.

      With respect to all Shares having voting rights (a) a shareholder may vote
the shares owned of record by him either in person or by proxy executed in
writing by the shareholder or by his duly authorized attorney-in-fact, provided
that no proxy shall be valid after eleven months from its date unless otherwise
provided in the proxy and (b) in all elections for directors every shareholder
shall have the right to vote, in person or by proxy, the Shares owned of record
by him, for as many persons as there are directors to be elected and for whose
election he has a right to vote.

                                   ARTICLE III

                               BOARD OF DIRECTORS

      Section 1. General Powers. The property, affairs and business of the
Corporation shall be managed by the Board of Directors, provided, however, that
the Board of Directors may authorize the Corporation to enter into an agreement
or agreements with any person, corporation, association, partnership or other
organization, subject to the Board's supervision and control, for the purpose of
providing managerial, investment advisory and related services to the
Corporation which may include management or supervision of the investment
portfolio of the Corporation.

<PAGE>

      Section 2. Number, Class Quorum, Election, Term of Office and
Qualifications. The Board of Directors of the Corporation shall consist of not
less than three or more than fifteen persons, none of whom need be stockholders
of the Corporation. The number of directors (within the above limits) shall be
determined by the Board of Directors from time to time, as it sees fit, by vote
of a majority of the whole Board. Directors shall consist of one class only. The
directors shall be elected at each annual meeting of stockholders and, whether
or not elected for a specific term, shall hold office, unless sooner removed,
until their respective successors are elected and qualify. One-third of the
whole Board, but in no event less than two, shall constitute a quorum for the
transaction of business, but if at any meeting of the Board there shall be less
than a quorum present, a majority of the directors present may adjourn the
meeting from time to time until a quorum shall have been obtained, when any
business may be transacted which might have been transacted at a meeting as
originally convened. No notice of an adjourned meeting of the directors other
than an announcement of the time and place thereof at the preceding meeting
shall be required. The acts of the majority of the directors present at any
meeting at which there is a quorum shall be the acts of the Board, except as
otherwise provided by law, by the Articles of Incorporation or by these By-laws.

      Section 3. Vacancies. The Board of Directors, by vote of a majority of the
whole Board, may elect directors to fill vacancies in the Board resulting from
an increase 


                                       7
<PAGE>

in the number of directors or from any other cause. Directors so chosen shall
hold office until their respective successors are elected and qualify, unless
sooner displaced pursuant to law or by these By-laws. The stockholders, at any
meeting called for the purpose, may, with or without cause, remove any director
by the affirmative vote of the holders of a majority of the votes entitled to be
cast, and at any meeting called for the purpose may fill the vacancy in the
Board thus caused.

      Section 4. Regular Meetings. Regular meetings of the Board of Directors
shall be held at such time and place, within or without the State of Maryland,
as may from time to time be fixed by Resolution of the Board or as may be
specified in the notice of any meeting. No notice of regular meetings of the
Board shall be required except as required by the Investment Company Act of
1940, as amended.

        Section 5. Special Meetings. Special meetings of the Board of Directors
may be called from time to time by the Chairman of the Board, the President, any
Vice President or any two directors. Each special meeting of the Board shall be
held at such place, either within or outside of the State of Maryland, as shall
be designated in the notice of such meeting. Notice of each such meeting shall
be mailed to each director, at his residence or usual place of business, at
least two days before the day of the meeting, or shall be directed to him at
such place by telegraph or cable, or be delivered to him personally not later
than the day before the day of the meeting. Every such notice shall state the
time


                                       8
<PAGE>

and place of the meeting but need not state the purposes thereof, except as
otherwise expressly provided in these By-laws or by statute.

      Section 6. Telephonic Conference Meetings. Any meeting of the Board or any
committee thereof may be held by conference telephone, regardless where each
director may be located at the time, by means of which all persons participating
in the meeting can hear each other, and participation in such meeting in such
manner shall constitute presence in person at such meeting, except where the
Investment Company Act of 1940, as amended, specifically requires that the vote
of such director be cast in person.

      Section 7. Fees and Expenses. The directors shall receive such fees and
expenses for services to the Corporation as may be fixed by the Board of
Directors, subject however, to such limitations as may be provided in the
Articles of Incorporation. Nothing herein contained shall be construed to
preclude any director from serving the Corporation in any other capacity as an
officer, agent or otherwise and receiving compensation therefor.

      Section 8. Transactions with Directors. Except as otherwise provided by
law or in the Articles of Incorporation, a director of the Corporation shall not
in the absence of fraud be disqualified from office by dealing or contracting
with the Corporation either as a vendor, purchaser or otherwise, nor in the
absence of fraud shall any transaction or contract of the Corporation be void or
voidable or affected by reason of the fact that any


                                       9
<PAGE>

director, or any firm of which any director is a member, or any corporation of
which any director is an officer, director or stockholder, is in any way
interested in such transaction or contract; provided that at the meeting of the
Board of Directors, at which said contract or transaction is authorized or
confirmed, the existence of an interest of such director, firm or corporation is
disclosed or made known and there shall be present a quorum of the Board of
Directors a majority of which, consisting of directors not so interested, shall
approve such contract or transaction. Nor shall any director be liable to
account to the Corporation for any profit realized by him from or through any
such transaction or contract of the Corporation ratified or approved as
aforesaid, by reason of the fact that he or any firm of which he is a member, or
any corporation of which he is an officer, director, or stockholder, was
interested in such transaction or contract. Directors so interested may be
counted when present at meetings of the Board of Directors for the purpose of
determining the existence of a quorum. Any contract, transaction or act of the
Corporation or of the Board of Directors (whether or not approved or ratified as
hereinabove provided) which shall be ratified by a majority of the votes cast at
any annual or special meeting at which a quorum is present called for such
purpose, or approved in writing by a majority in interest of the stockholders
having voting power without a meeting, shall, except as otherwise provided by
law, be valid and as binding as through ratified by every stockholder of the
Corporation.


                                       10
<PAGE>

      Section 9. Committees. The Board of Directors may, by resolution adopted
by a majority of the whole Board, designate one or more committees each such
committee to consist of two or more directors of the Corporation, which, to the
extent permitted by law and provided in said resolution, shall have and may
exercise the powers of the Board over the business and affairs of the
Corporation, and may have power to authorize the seal of the Corporation to be
affixed to all papers which may require it. Such committee or committees shall
have such name or names as may be determined from time to time by resolution
adopted by the Board of Directors. A majority of the members of any such
committee may determine its action and fix the time and place of its meetings,
unless the Board of Directors shall otherwise provide. The Board of Directors
shall have power at any time to change the membership of, to fill vacancies in,
or to dissolve any such committee.

      Section 10. Written Consents. Any action required or permitted to be taken
at any meeting of the Board of Directors or by any committee thereof may be
taken without a meeting, if a written consent thereto is signed by all members

      Section 11. Waiver of Notice. Whenever under the provisions of these
By-laws, or of the Articles of Incorporation, or of any of the laws of the State
of Maryland, or other applicable statute, the Board of Directors is authorized
to hold any meeting or take any action after notice or after the lapse of any
prescribed period of time, a waiver thereof, in writing, signed by the person or
persons entitled to such notice or lapse of time, whether signed before or after
the time of meeting or action stated herein, shall be deemed equivalent thereto.
The presence at any meeting of a person or persons entitled to notice thereof
shall be deemed a waiver of such notice as to such person or persons.

                                   ARTICLE IV

                                    OFFICERS

      Section 1. Number and Designation. The Board of Directors shall each year
appoint from among their members a Chairman and a President of the Corporation,
and shall appoint one or more Vice Presidents, a Secretary and a Treasurer and,
from time to time, any other officers and agents as it may deem proper. Any two
of the above-mentioned offices, except those of the President and a Vice
President, may be held by the


                                       12
<PAGE>

same person, but no officer shall execute, acknowledge or verify any instrument
in more than one capacity if such instrument be required by law or by these
By-laws to be executed, acknowledged or verified by any two or more officers.

      Section 2. Term of Office. The term of office of all officers shall be one
year or until their respective successors are chosen; but any officer or agent
chosen or appointed by the Board of Directors may be removed, with or without
cause, at any time, by the affirmative vote of a majority of the members of the
Board then in office.

      Section 3. Duties. Subject to such limitations as the Board of Directors
may from time to time prescribe, the officers of the Corporation shall each have
such powers and duties as generally appertain to their respective offices, as
well as such powers and duties as from time to time may be conferred by the
Board of Directors.

                                    ARTICLE V

                              CERTIFICATE OF STOCK

      Section 1. Form and Issuance. Each stockholder of the Corporation, of a
particular Class, shall be entitled upon request, to a certificate or
certificates, in such form as the Board of Directors may from time to time
prescribe, which shall represent and certify the number of shares of stock of
the Corporation of that Class of stock owned by


                                       13
<PAGE>

such stockholder. The certificates for shares of stock of the Corporation shall
bear the signature, either manual or facsimile, of the Chairman of the Board,
the President or a Vice President and the Treasurer or an Assistant Treasurer or
the Secretary or an Assistant Secretary, and shall be sealed with the seal of
the Corporation or bear a facsimile of such seal. The validity of any stock
certificate shall not be affected if any officer whose signature appears thereon
ceases to be an officer of the Corporation before such certificate is issued.

      Section 2. Transfer of Stock. The shares of stock of the Corporation of
any Class shall be transferable on the books of the Corporation by the holder
thereof in person or by a duly authorized attorney, upon surrender for
cancellation of a certificate or certificates for a like number of shares, with
a duly executed assignment and power of transfer endorsed thereon or attached
thereto, or, if no certificate has been issued to the holder in respect of
shares of stock of the Corporation, upon receipt of written instructions, signed
by such holder, to transfer such shares from the account maintained in the name
of such holder by the Corporation or its agent. Such proof for the authenticity
of the signatures as the Corporation or its agent may reasonably require shall
be provided.

      Section 3. Lost, Stolen, Destroyed and Mutilated Certificates. The holder
of any stock of the Corporation of any Class shall immediately notify the
Corporation of any loss, theft, destruction or mutilation of any certificate
therefore, and the Board of


                                       14
<PAGE>

Directors may, in its discretion, cause to be issued to him a new certificate or
certificates of stock of the same Class, upon the surrender of the mutilated
certificate or in case of loss, theft or destruction of the certificate upon
satisfactory proof of such loss, theft or destruction; and the Board of
Directors may, in its discretion, require the owner of the lost, stolen or
destroyed certificate, or his legal representatives, to give to the Corporation
and to such registrar or transfer agent as may be authorized or required to
countersign such new certificate or certificates, a bond, in such sum as they
may direct, and with such surety or sureties, as they may direct, as indemnity
against any claim that may be made against them or any of them on account of or
in connection with the alleged loss, theft, or destruction of any such
certificate.

      Section 4. Record Date. The Board of Directors may fix, in advance, a date
as the record date for the purpose of determining stockholders, of any Class,
entitled to notice of, or to vote at, any meeting of stockholders, of any Class,
or stockholders of any Class entitled to receive payment of any dividend or the
allotment of any rights, or in order to make a determination of stockholders of
any Class for any other proper purpose. Such date, in any case, shall be not
more than 90 days, and in case of a meeting of


                                       15
<PAGE>

stockholders, not less than 10 days, prior to the date on which the particular
action requiring such determination of stockholders is to be taken. In lieu of
fixing a record date, the Board of Directors may provide that the stock transfer
books shall be closed for a stated period but not to exceed, in any case, 20
days prior to the date of any meeting of stockholders or the date for payment of
any dividend or the allotment of rights. If the stock transfer books are closed
for the purpose of determining stockholders entitled to notice of or to vote at
a meeting of stockholders, such books shall be closed for at least 10 days
immediately preceding such meeting. If no record date for the determination of
stockholders entitled to notice of, or to vote at, a meeting of stockholders
shall be at the close of business on the day on which notice of the meeting is
mailed or the day 30 days before the meeting, whichever is the closer date to
the meeting, and the record date for the determination of stockholders entitled
to receive payment of a dividend or an allotment of any rights shall be at the
close of business on the day on which the resolution of the Board


                                       16
<PAGE>

of Directors declaring the dividend or allotment of rights is adopted, provided
that the payment or allotment date shall not be more than 90 days after the date
of the adoption of such resolution.

                                   ARTICLE VI

                                 CORPORATE BOOKS

such place or places as the Board of Directors may from time to time determine.
The original or duplicate stock ledger shall be maintained at the office of the
Corporation's transfer agent.

                                   ARTICLE VII

                                   SIGNATURES

                                   ARTICLE IX

                                 CORPORATE SEAL

      The corporate seal of the Corporation shall consist of a flat faced
circular die with the word "Maryland" together with the name of the Corporation,

Directors may from time


                                       18
<PAGE>

to time determine, cut or engraved thereon. In lieu of the corporate seal, when
so authorized by the Board of Directors or a duly empowered committee thereof, a
facsimile thereof may be impressed or affixed or reproduced.

                                    ARTICLE X

                                 INDEMNIFICATION

      As part of the consideration for agreeing to serve and serving as a
director of the Corporation, each director of the Corporation shall be
indemnified by the Corporation against every judgement, penalty, fine,
settlement, and reasonable expense (including attorneys' fees) actually incurred
by the director in connection with any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative, in

in that capacity or status as such, and the amount of every such judgement,
penalty, fine,


                                       19

Corporation, subject only to the conditions and limitations imposed by the
applicable provisions of Section 2-418 of the Corporations and Associations
Article of the Annotated Code of the State of Maryland and by the provisions of
Section 17(h) of the United States Investment Company Act of 1940 as interpreted
and as required to be implemented by Securities and Exchange Commission Release
No. IC-11330 of September 4, 1980. The foregoing shall not limit the authority
of the Corporation to indemnify any of its officers, employees or agents to the
extent consistent with applicable law.

                                   ARTICLE XI
