                                                                Large-Cap Series


GOAL

     The Fund's  investment  objective is long-term growth of capital and income
     without excessive fluctuations in market value.

PRINCIPAL STRATEGY

     To pursue this goal, the Fund purchases stocks of large, seasoned, U.S. and
     multinational companies which we believe are undervalued.  The Fund chooses
     stocks using:

     o    quantitative  research to identify  which stocks we believe  represent
          the best bargains

     o    fundamental research to learn about a company's operating environment,
          resources  and  strategic  plans  and  to  assess  its  prospects  for
          exceeding earnings expectations

     o    business cycle analysis to determine how buying or selling  securities
          changes  our overall  portfolio's  sensitivity  to interest  rates and
          economic conditions

     The Fund is intended for investors  looking for  long-term  growth with low
     fluctuations  in  market  value.  For  this  reason,  we  will  forgo  some
     opportunities for gains when, in our judgment, they are too risky. The Fund
     tries to keep its assets  invested  in  securities  selling  at  reasonable
     prices in relation to value.

     While there is the risk that an investment may never reach what we think is
     its full value,  or may go down in value,  our emphasis on large,  seasoned
     company  bargain stocks may limit our downside risk because  bargain stocks
     in theory are already  underpriced and large,  seasoned company stocks tend
     to be less volatile than small company stocks.

     We  generally  sell a stock when we think it is no longer a bargain,  seems
     less likely to benefit from the current  market and  economic  environment,
     shows deteriorating fundamentals, or falls short of our expectations.

     While typically fully invested,  at times we may take a temporary defensive
     position  by  investing  some  of the  Fund's  assets  in  short-term  debt
     securities.  This could  reduce the benefit  from any upswing in the market
     and prevent the Fund from achieving its investment objective.


MAIN RISKS

     The Fund is subject to the general risks and considerations associated with
     equity  investing,  as well as the particular risks associated with bargain
     stocks.  The  value  of your  investment  will  fluctuate  in  response  to
     movements in the stock  market in general and to the changing  prospects of
     individual companies in which the Fund invests.  Bargain stocks may perform
     differently  than the market as a whole and other types of stocks,  such as
     small company stocks and growth stocks.  This is because different types of
     stocks tend to shift in and out of favor  depending  on market and economic
     conditions.  The  market  may  fail to  recognize  the  intrinsic  value of
     particular  bargain  stocks for a long  time.  In  addition,  if the Fund's
     assessment  of a  company's  value  or  prospects  for  exceeding  earnings
     expectations or market conditions is wrong, the Fund could suffer losses or
     produce poor performance relative to other funds, even in a rising market.

     An  investment  in the Fund is not a bank  deposit  and is not  insured  or
     guaranteed  by the  Federal  Deposit  Insurance  Corporation  or any  other
     government  agency.  The Fund is not a complete  investment program and may
     not be appropriate for all investors. You could lose money in the Fund.



We or the Fund  refers to either the  Large-Cap  Series or the  Small-Cap  Value
Series of Lord Abbett Research Fund, Inc. (the "Company").



About each Fund. Each Fund is a professionally  managed  portfolio of securities
purchased  with the pooled  money of  investors.  Each Fund strives to reach its
stated goals, although as with all mutual funds, cannot guarantee results.

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  high
liquidity in the market.

Bargain  stocks are stocks of companies  that appear under- priced  according to
certain financial measurements of their intrinsic worth or business prospects.


Growth stocks are stocks which exhibit faster-than-average gains
in earnings and are expected to continue profit growth at a high level, but also
tend to be more volatile than bargain stocks.


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

PERFORMANCE


     The bar chart and  table  below  provide  some  indication  of the risks of
     investing  in the  Fund  by  illustrating  the  variability  of the  Fund's
     returns.  Each assumes  reinvestment  of dividends and  distributions.  The
     Fund's past  performance  is not  necessarily an indication of how the Fund
     will perform in the future.

     The bar chart shows changes in the performance of the Fund's Class A shares
     from calendar year to calendar year.  This chart does not reflect the sales
     charges  applicable to Class A shares. If the sales charges were reflected,
     returns would be less.

(1)  A  contingent  deferred  sales  charge of 1.00% may be  assessed on certain
     redemptions  of (a) Class A shares  made  within 24  months  following  any
     purchases  made without a sales charge,  and (b) Class C shares if they are
     redeemed before the first anniversary of their purchase.

(2)  Class B shares will convert to Class A shares on the eighth  anniversary of
     your original purchase of Class B shares.
(3)  The annual  operating  expenses have been restated from fiscal year amounts
     to reflect current fees.
(4)  Because  12b-1 fees are paid out on an ongoing  basis,  over time they will
     increase  the cost of your  investment  and may cost you more  than  paying
     other types of sales charges.

Example
- --------------------------------------------------------------------------------
This  Example is intended to help you compare the cost of  investing in the Fund
with the cost of investing in other mutual  funds.  This  Example,  like that in
other  funds'  prospectuses,  assumes  that you  invest  $10,000  in the Fund at
maximum sales charge, if any, for the time periods indicated and then redeem all
of your shares at the end of those  periods.  The Example also assumes that your
investment  has a 5% return  each year and that the  Fund's  operating  expenses
remain the same.  Although  your actual  costs may be higher or lower,  based on
these assumptions your costs (including any applicable contingent deferred sales
charges) would be:

Management fees are payable to Lord, Abbett & Co. ("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 shareholder
service fees and professional fees.

GOAL

     The Fund's investment objective is long-term capital appreciation.

PRINCIPAL STRATEGY

     To pursue this goal, the Fund invests in smaller, less well-known companies
     with market  capitalizations  of less than $2 billion  which we believe the
     market  undervalues.  Under normal  circumstances,  the Fund will invest at
     least 65% of its total  assets in the stocks of these  companies.  The Fund
     chooses stocks using:

     o    quantitative research to identify stocks we believe represent the best
          bargains.  As part of this  process,  we may  look at the  price  of a
          company's  stock in  relation to book value,  a company's  sales,  the
          value of its assets, its earnings and cash flow

     o    fundamental  research to evaluate a company's  operating  environment,
          resources  and  strategic  plans to assess its prospects for exceeding
          earnings expectations

     We  generally  sell a stock when we think it is no longer a bargain,  seems
     less likely to benefit from the current  market and  economic  environment,
     shows deteriorating fundamentals, or falls short of our expectations.

     This Fund is intended for  investors  who are willing to withstand the risk
     of  short-term  price  fluctuations  in exchange for  attractive  potential
     long-term returns.

     While typically fully invested,  at times we may take a temporary defensive
     position  by  investing  some  of the  Fund's  assets  in  short-term  debt
     securities.  This could  reduce the benefit  from any upswing in the market
     and prevent the Fund from achieving its investment objective.



MAIN RISKS

     The Fund is subject to the general risks and considerations associated with
     equity  investing,  as well as the particular  risks  associated with value
     stocks.  The market may fail to recognize the intrinsic value of particular
     bargain stocks for a long time. In addition,  if the Fund's assessment of a
     company's value or prospects for exceeding earnings  expectations or market
     conditions  is  wrong,  the  Fund  could  suffer  losses  or  produce  poor
     performance relative to other funds, even in a rising market.

     Investing  in  small  companies   generally  involves  greater  risks  than
     investing in the stocks of large  companies.  Small companies may have less
     experienced management and unproven track records. They may rely on limited
     product lines and have limited  financial  resources.  Small company stocks
     tend to have fewer shares  outstanding  and trade less  frequently than the
     stocks of larger companies. As a result, there may be less liquidity in the
     prices  of  small  company   stocks,   subjecting  them  to  greater  price
     fluctuations than larger company stocks.

     An  investment  in the Fund is not a bank  deposit  and is not  insured  or
     guaranteed  by the  Federal  Deposit  Insurance  Corporation  or any  other
     government  agency.  The Fund is not a complete  investment program and may
     not be appropriate for all investors. You could lose money in the Fund.



Small companies often are younger and less well-established, with a potential to
be faster-growing but often 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.



Value Stocks,  also referred to as bargain stocks,  are stocks of companies that
appear  under- priced  according to certain  finan- cial  measurements  of their
intrinsic worth or business prospects.

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

PERFORMANCE
     The bar chart and  table  below  provide  some  indication  of the risks of
     investing  in the  Fund  by  illustrating  the  variability  of the  Fund's
     returns.  Each assumes  reinvestment  of dividends and  distributions.  The
     Fund's past  performance  is not  necessarily an indication of how the Fund
     will perform in the future.

     The bar chart shows changes in the performance of the Fund's Class A shares
     from calendar year to calendar year.  This chart does not reflect the sales
     charges  applicable to Class A shares. If the sales charges were reflected,
     returns would be less.

(1)  A  contingent  deferred  sales  charge of 1.00% may be  assessed on certain
     redemptions  of (a) Class A shares  made  within 24  months  following  any
     purchases  made without a sales charge,  and (b) Class C shares if they are
     redeemed before the first anniversary of their purchase.

(2)  Class B shares will convert to Class A shares on the eighth  anniversary of
     your original purchase of Class B shares.
(3)  The annual  operating  expenses have been restated from fiscal year amounts
     to reflect current fees.
(4)  Because  12b-1 fees are paid out on an ongoing  basis,  over time they will
     increase  the cost of your  investment  and may cost you more  than  paying
     other types of sales charges.

Example
- --------------------------------------------------------------------------------
This  Example is intended to help you compare the cost of  investing in the Fund
with the cost of investing in other mutual  funds.  This  Example,  like that in
other  funds'  prospectuses,  assumes  that you  invest  $10,000  in the Fund at
maximum sales charge, if any, for the time periods indicated and then redeem all
of your shares at the end of those  periods.  The Example also assumes that your
investment  has a 5% return  each year and that the  Fund's  operating  expenses
remain the same.  Although  your actual  costs may be higher or lower,  based on
these assumptions your costs (including any applicable contingent deferred sales
charges)  would be:

You would have paid the following expenses if you did not redeem your shares:

Class A shares            $723        $1,033             $1,366           $2,304

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 shareholder
service fees and professional fees.

PURCHASES
     The Funds offer four classes of shares in this prospectus: Classes A, B, C,
     and P, each with different expenses and dividends.  You may purchase shares
     at the net asset value ("NAV") per share  determined  after we receive your
     purchase  order  submitted  in proper  form.  A front-end  sales  charge is
     normally  added to the NAV in the case of the Class A  shares.  There is no
     front-end  sales  charge in the case of the  Class B,  Class C, and Class P
     shares,  although there may be a contingent  deferred sales charge ("CDSC")
     on Class B and Class 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   purchase   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.

NAV per share for each class of Fund shares is  calculated  each business day at
the close of regular  trading on the New York Stock Exchange  ("NYSE")  normally
4:00 p.m.  Eastern time.  Purchases and sales of Fund shares are executed at the
NAV next  determined  after the Fund  receives  your  order in proper  form.  In
calculating NAV, securities for which market quotations are available are valued
at those quotations.  Securities for which such quotations are not available are
valued at fair value under procedures approved by the Board of the Company.


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

To minimize the amount of any CDSC,  each Fund redeems  shares in the  following
order:

1.   shares acquired by reinvestment of dividends and capital gains (always free
     of a CDSC)

2.   shares  held for six years or more (Class B) or two years or more after the
     month of purchase (Class A) or one year or more (Class C)

3.   shares  held the longest  before the sixth  anniversary  of their  purchase
     (Class B) or before  the  second  anniversary  after the month of  purchase
     (Class  A) or before  the first  anniversary  of their  purchase  (Class C)
     Retirement  Plans  include  employer-sponsored  retirement  plans under the
     Internal Revenue Code, excluding Individual Retirement Accounts.

SALES 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 Funds'  shares and service its  shareholder  accounts.

     Sales compensation  originates from two sources as shown in the table "Fees
     and Expenses":  sales charges which are paid directly by shareholders;  and
     12b-1  distribution  fees that are paid out of each Fund's assets.  Service
     compensation  originates  from 12b-1  service  fees.  The total  12b-1 fees
     payable  with  respect to each  share  class of each Fund are up to .35% of
     Class A shares (plus distribution fees of up to 1.00% on certain qualifying
     purchases),  1.00% of Class B and C shares, and .45% of Class P shares. The
     amounts payable as compensation  to Authorized  Institutions,  such as your
     dealer,  are shown in the chart at the end of this prospectus.  The portion
     of such  compensation  paid to Lord Abbett  Distributor is discussed  under
     "Sales  Activities"  and  "Service  Activities."  Sometimes  we do not  pay
     compensation  where tracking data is not available for certain  accounts or
     where the Authorized  Institution waives part of the compensation.  In such
     cases, we may not require payment of any otherwise  applicable CDSC.

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

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

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

     You may purchase shares through any independent securities dealer who has a
     sales  agreement  with  Lord  Abbett  Distributor  or you can  fill out the
     attached  application  and send it to the Fund you  select  at the  address
     stated  below.  You should  carefully  read the  paragraph  below  entitled
     "Proper  Form" before  placing your order to ensure that your order will be
     accepted.


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

<PAGE>


     Name of Fund
     P.O. Box 219100
     Kansas City, MO 64121


     By Exchange. Telephone the Fund at 800-821-5129 to request an exchange from
     any eligible Lord Abbett-sponsored fund.

     Proper Form. An order  submitted  directly to the Fund must contain:  (1) a
     completed application, and (2) payment by check. When purchases are made by
     check,  redemption  proceeds  will not be paid  until the Fund or  transfer
     agent is  advised  that the  check  has  cleared,  which  may take up to 15
     calendar days. For more information call the Fund at 800-821-5129.


REDEMPTIONS


     By Broker.  Call your investment  professional  for  instructions on how to
     redeem your shares.

     By  Telephone.  To obtain the proceeds of a  redemption  of $50,000 or less
     from  your  account,  you or your  representative  should  call the Fund at
     800-821-5129.


     By Mail.  Submit a written  redemption  request  indicating  the name(s) in
     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 sell.

     Include all necessary signatures. If the signer has any Legal Capacity, the
     signature and capacity must be guaranteed by an Eligible Guarantor. Certain
     other legal documentation may be required.  For more information  regarding
     proper documentation call 800-821-5129.


     Normally a check  will be mailed to the  name(s)  and  address in which the
     account is registered (or otherwise  according to your instruction)  within
     three business days after receipt of your redemption request.  Your account
     balance  must be  sufficient  to cover the amount  being  redeemed  or your
     redemption order will not be processed.  Under unusual  circumstances,  the
     Fund may suspend redemptions, or postpone payment for more than seven days,
     as permitted by federal securities laws.


     To determine if a CDSC applies to a  redemption,  see "Class A share CDSC,"
     "Class B share CDSC," or "Class C share CDSC."


DISTRIBUTIONS AND TAXES
     Each  Fund  normally  pays  dividends  from its net  investment  income  as
     follows:  semi-annually  for  Large-Cap  Series and annually for  Small-Cap
     Value Series.  Each Fund  distributes net capital gains (if any) as capital
     gains   distributions  at  least  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 is the same for all shareholders  regardless of how long they
     have owned Fund shares or whether  distributions  are reinvested or paid in
     cash.

     Except in tax-advantaged accounts, any sale, redemption or exchange of Fund
     shares may be taxable to the shareholder.

     Information on the tax treatment of distributions,  including the source of
     dividends and  distributions  of capital gains by each Fund, will be mailed
     to shareholders each year.  Because everyone's tax situation is unique, you
     should  consult your tax adviser  regarding the treatment of  distributions
     under the federal,  state and local tax rules that apply to you, as well as
     the tax  consequences of gains or losses from the redemption or exchange of
     your shares.


Exchange  Limitations.  Exchanges should not be used to try to take advantage of
short-term swings in the market.  Frequent  exchanges create higher expenses for
the Fund.  Accordingly,  the Fund reserves the right to limit or terminate  this
privilege  for  any  shareholder   making  frequent  exchanges  or  abusing  the
privilege.  The Fund also may revoke the privilege for all shareholders  upon 60
days' written notice.

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

Eligible Guarantor is any broker or bank that is a member of the medallion stamp
program.  Most major securities  firms and banks are members of this program.  A
notary public is not an eligible guarantor.

OTHER INVESTMENT TECHNIQUES

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


     Adjusting Investment  Exposure.  Each Fund may, but is not required to, use
     various strategies to change its investment  exposure to adjust to changing
     security prices,  interest rates, currency exchange rates, commodity prices
     and  other  factors.   These  strategies  may  involve  buying  or  selling
     derivative  instruments,  such  as  options  and  futures  contracts,  swap
     agreements including interest rate swaps, caps, floors,  collars and rights
     and warrants.  Each Fund may use these  transactions to change the risk and
     return  characteristics  of its  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 a
     loss if the counterparty to a transaction does not perform as promised.





     Futures  Contracts and Options on Futures  Contracts.  A financial  futures
     transaction  is an  exchange-traded  contract  to  buy or  sell a  standard
     quantity  and  quality  of a  financial  instrument  or index at a specific
     future date and price.  Each Fund may purchase  and sell futures  contracts
     and options  thereon.  Both the Large-Cap  Series and the  Small-Cap  Value
     Series will not enter into any futures contracts or options thereon, if the
     aggregate market value of the securities  covered by such contracts exceeds
     50% of the total assets of the Fund entering into the transaction


     A Fund's ability to enter into financial transactions is limited by certain
     tax requirements in order to continue to qualify as a regulated  investment
     company.



     Foreign  Securities.  The Large-Cap Series,  and the Small-Cap Value Series
     will  limit  their  investments  in  foreign  securities  to 10%  of  their
     respective total assets.  Foreign markets and the securities traded in them
     are  not  subject  to the  same  degree  of  regulation  as  U.S.  markets.
     Securities clearance and settlement  procedures may be different in foreign
     countries. There may be less trading volume in foreign markets,  subjecting
     the  securities  traded in them to higher price  fluctuations.  Transaction
     costs may be higher in foreign markets.  A Fund may hold foreign securities
     which trade on days when the Fund does not sell  shares.  As a result,  the
     value of the Fund's portfolio securities may change on days an investor may
     not purchase or sell Fund shares.

     Foreign issuers are generally not subject to similar,  uniform  accounting,
     auditing and financial  reporting  requirements  as U.S.  issuers.  Foreign
     investments  may be  affected  by changes  in  currency  rates or  currency
     controls.  Certain  foreign  countries may limit a Fund's ability to remove
     its assets from the  country.  With respect to certain  foreign  countries,
     there is a possibility of  nationalization,  expropriation  or confiscatory
     taxation,  imposition of withholding or other taxes and political or social
     instability  which could affect  investments  in those  countries.




     Options Transactions. The Small-Cap Value Series may purchase and write put
     and call options on securities or stock indices that are traded on national
     securities exchanges.

     A put  option  gives the  buyer of the  option  the right to sell,  and the
     seller of the option  the  obligation  to buy,  the  underlying  instrument
     during the option period. The Small-Cap



                                                         For More Information 15


<PAGE>


     Value  Series may write only  covered  put options to the extent that cover
     for  such  options  does not  exceed  25% of the  Fund's  net  assets.  The
     Small-Cap  Value Series will not purchase an option if, as a result of such
     purchase, more than 20% of its net assets would be invested in premiums for
     such options.

     A call  option  gives the  buyer of the  option  the right to buy,  and the
     writer  (seller)  of the  option the  obligation  to sell,  the  underlying
     instrument.  The Small-Cap Value Series and the Large-Cap  Series may write
     (sell) only "covered" options. This means that the Funds may only sell call
     options on securities which the Funds own. When a Fund writes a call option
     it gives up the potential for gain on the  underlying  securities in excess
     of the  exercise  price of the option  during the period that the option is
     open. Each Fund will only write "covered" call options on securities having
     an aggregate market value not to exceed 5% of its gross assets.




     Rights and Warrants.  Each Fund may invest up to 5% of its assets in rights
     and warrants to purchase  securities.  Rights represent a privilege offered
     to holders of record of issued securities (usually on a pro-rata basis) for
     additional  securities of the same class, or 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.

     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
     after their expiration date.


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

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

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

     Eligible  Fund. An Eligible Fund is any Lord  Abbett-sponsored  fund except
     for  (1)  certain  tax-free,   single-state   funds  where  the  exchanging
     shareholder  is a resident  of a state in which such a Fund is not  offered
     for sale;  (2) Lord Abbett Equity Fund;  (3) Lord Abbett  Series Fund;  (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 accounts 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 Class B share investment bears to
     the total investment.

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


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

     Mutual Fund Fee Based Program.  Certain  unaffiliated  authorized  brokers,
     dealers,  registered  investment  advisers or other financial  institutions
     ("entities")   who  either  (1)  have  an  arrangement   with  Lord  Abbett
     Distributor in accordance  with certain  standards  approved by Lord Abbett
     Distributor,  providing  specifically  for  the  use  of  our  shares  (and
     sometimes providing for acceptance of orders for such shares on our behalf)
     in particular  investment  products made  available for a fee to clients of
     such entities, or (2) 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:  (1)  an  individual,  (2) an
     individual  and his or her spouse and children under the age of 21, and (3)
     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.



RECENT PERFORMANCE


     Large-Cap Series.  During 1999, the Fund established and added to positions
     in stocks that, in our opinion,  were undervalued due to investor sentiment
     rather than deteriorating  company  fundamentals.  A number of positions we
     established or  strengthened in  telecommunications,  technology and select
     financial services companies performed well. A slight increase in long-term
     interest rates, brought on in part by a rise in commodity prices,  resulted
     in markdowns on our electric utility holdings.

     Small-Cap Value Series.  In April and May many small-cap  stocks  performed
     well,  rebounding from their 1998 and first quarter 1999 price levels. This
     was  generally a result of improving  investor  sentiment  and an increased
     interest in the sector,  which had become  significantly  undervalued  as a
     result of the "flight to quality"  that drove  investors  to  large-company
     stocks  and a period of  tax-loss  selling  that put  further  pressure on

     small-cap  stock  prices in 1998.  Holdings  in the  technology  and energy
     sectors turned in strong performance as the market bounced back. We believe
     that select  investments in these areas may provide  value,  given existing
     price levels and our current interest rate forecasts.
     During the fourth quarter of 1999, we anticipated that the domestic economy
     would  continue to grow,  fueled in part by strong  consumer  spending.  If
     recovery  in Asia  also  continues,  we  anticipate  that  global  economic
     expansion is likely in 2000.  With the general rise in interest rates we've
     experienced  since the  beginning  of 1999,  we do not expect  inflation to
     exceed our  earlier  forecasts. Given these  conditions,  we believe  that
     value stocks will perform well relative to growth  stocks.  It is important
     to  note,  however,  that we work to  apply  our  bottom-up,  stock-picking
     strategy regardless of market conditions because, in our opinion,  over the
     long term, a value-oriented, disciplined approach to investing provides the
     greatest potential for achieving consistent, above-market returns.

GOAL

     The Fund's investment objective is capital appreciation.



PRINCIPAL STRATEGY

     To pursue this goal,  we invest  primarily  in common  stocks of  mid-sized
     companies with market  capitalizations  between $1 billion and $10 billion.
     The  Fund  uses a growth  style  of  investing  which  means  that we favor
     companies that show the potential for strong  revenue and earnings  growth.
     Under normal circumstances,  the Fund will invest at least 65% of its total
     assets in growth company stocks.

     Typically, in choosing stocks, we look for mid-sized companies using:

     o    quantitative  research  to identify  companies  with  superior  growth
          possibilities

     o    fundamental  research to identify companies likely to produce superior
          returns over a two to five year time frame,  by analyzing the dynamics
          in each company within its industry and within the economy

     While typically fully invested,  at times we may take a temporary defensive
     position by investing some of the Fund's assets in cash  equivalents.  This
     could  reduce the  benefit  from any  upswing in the market and prevent the
     Fund from achieving its investment objective.


MAIN RISKS

     The Fund is subject to the general risks and considerations associated with
     equity  investing.  The value of your investment will fluctuate in response
     to movements in the stock market in general,  and to the changing prospects
     of individual companies in which the Fund invests.

     The Fund has particular risks  associated with growth stocks.  Different
     types of stocks shift in and out of favor  depending on market and economic
     conditions Growth companies may grow faster than other companies
     which may result in more volatility in their stock prices. In addition,  if
     the  Fund's  assessment  of a  company's  potential  for  growth  or market
     conditions  is wrong,  it could suffer  losses or produce poor  performance
     relative to other funds, even in a rising market.

     An  investment  in the Fund is not a bank  deposit  and is not  insured  or
     guaranteed  by the  Federal  Deposit  Insurance  Corporation  or any  other
     government  agency.  The Fund is not a complete  investment program and may
     not be appropriate for all investors. You could lose money in the Fund.



We or the Fund refers to the Lord Abbett Growth  Opportunities Fund, a portfolio
of Lord Abbett Research Fund, Inc. (the "Company").



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

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 value stocks.

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

PERFORMANCE
     The bar chart and  table  below  provide  some  indication  of the risks of
     investing  in the  Fund  by  illustrating  the  variability  of the  Fund's
     returns.  Each assumes  reinvestment  of dividends and  distributions.  The
     Fund's past  performance  is not  necessarily an indication of how the Fund
     will perform in the future.

     The bar chart shows changes in the performance of the Fund's Class A shares
     from calendar year to calendar year.  This chart does not reflect the sales
     charges  applicable to Class A shares. If the sales charges were reflected,
     returns would be less.

     market  sectors  in which the Fund  invests.  The  Fund's  returns  reflect
     payment of the maximum applicable front-end or deferred sales charges.

(1)  A  contingent  deferred  sales  charge of 1.00% may be  assessed on certain
     redemptions  (a) of Class A shares  made  within  24 months  following  any
     purchases  made without a sales charge,  and (b) Class C shares if they are
     redeemed before the first anniversary of their purchase.
(2)  Class B shares will convert to Class A shares on the eighth  anniversary of
     your original purchase of Class B shares.
(3)  The annual  operating  expenses have been restated from fiscal year amounts
     to reflect current fees.
(4)  Because  12b-1 fees are paid out on an ongoing  basis,  over time they will
     increase  the cost of your  investment  and may cost you more  than  paying
     other types of sales charges.

Example
- --------------------------------------------------------------------------------

This  Example is intended to help you compare the cost of  investing in the Fund
with the cost of investing in other mutual  funds.  This  Example,  like that in
other  funds'  prospectuses,  assumes  that you  invest  $10,000  in the Fund at
maximum sales charge, if any, for the time periods indicated and then redeem all
of your shares at the end of those  periods.  The Example also assumes that your
investment  has a 5% return  each year and that the  Fund's  operating  expenses
remain the same.  Although  your actual  costs may be higher or lower,  based on
these assumptions your costs (including any applicable contingent deferred sales
charges) would be:

Share Class                1 Year        3 Years        5 Years         10 Years

Class A shares               $733         $1,065        $1,420            $2,417

- --------------------------------------------------------------------------------
You would have paid the following expenses if you did not redeem your shares:

Class A shares               $733         $1,065        $1,420            $2,417

Class P shares               $178         $  551        $  949            $2,062



Management fees are payable to Lord, Abbett & Co. ("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 shareholder
service fees and professional fees.

PURCHASES


     The Fund offers four classes of shares in this prospectus: Classes A, B ,C,
     and P, each with different expenses and dividends.  You may purchase shares
     at the net asset value ("NAV") per share  determined  after we receive your
     purchase  order  submitted  in proper  form.  A front-end  sales  charge is
     normally  added to the NAV, in the case of the Class A shares.  There is no
     front-end  sales  charge in the case of the  Class B,  Class C, and Class P
     shares,  although there may be a contingent  deferred sales charge ("CDSC")
     on Class B and Class C shares as described below.s


     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.

NAV per share for each class of Fund shares is  calculated  each business day at
the close of regular trading on the New York Stock Exchange  ("NYSE"),  normally
4:00 p.m.  Eastern time.  Purchases and sales of Fund shares are executed at the
NAV next  determined  after the Fund  receives  your  order in proper  form.  In
calculating NAV, securities for which market quotations are available are valued
at those quotations.  Securities for which such quotations are not available are
valued at fair value under procedures approved by the Board of the Company.

     See "Systematic  Withdrawal Plan" under "Services For Fund Investors" below
     for more information on CDSCs with respect to Class B shares.

     Class C Share CDSC. The 1% CDSC for Class C shares normally  applies if you
     redeem your shares  before the first  anniversary  of the  purchase of such
     shares.

     Class P Shares.  Class P shares have lower annual expenses than Class B and
     Class C shares, no front-end sales charge,  and no CDSC. Class P shares are
     currently  sold and redeemed at NAV (a) pursuant to a Mutual Fund Fee Based
     Program or (b) to the  trustees of, or  employer-sponsors  with respect to,
     pension or retirement plans with at least 100 eligible employees (such as a
     plan under Section 401(a),  401(k) or 457(b) of the Internal  Revenue Code)
     which engage an investment  professional  providing, or participating in an
     agreement  to  provide,   certain   recordkeeping,   administrative  and/or
     sub-transfer  agency  services  to  the  Fund  on  behalf  of the  Class  P
     shareholders.



SALES COMPENSATION


     As part of its  plan for  distributing  shares,  the  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, as shown in the table "Fees
     and Expenses":  sales charges which are paid directly by shareholders;  and
     12b-1  distribution



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

To minimize  the amount of any CDSC,  the Fund redeems  shares in the  following
order:

1.   shares acquired by reinvestment of dividends and capital gains (always free
     of a CDSC)

2.   shares  held for six years or more (Class B) or two years or more after the
     month of purchase (Class A) or one year or more (Class C)

3.   shares  held the longest  before the sixth  anniversary  of their  purchase
     (Class B) or before  the  second  anniversary  after the month of  purchase
     (Class  A) or before  the first  anniversary  of their  purchase  (Class C)
     investors.


                                                               Your Investment 7


<PAGE>


     fees  that  are  paid  out  of  the  Fund's  assets.  Service  compensation
     originates  from 12b-1  service  fees.  The total 12b-1 fees  payable  with
     respect  to each share  class are .35% of Class A shares,  1.00% of Class B
     and Class C shares,  and .45% of Class P shares.  The  amounts  payable  as
     compensation to Authorized Institutions,  such as your dealer, are shown in
     the chart at the end of this prospectus.  The portion of such  compensation
     paid to Lord Abbett  Distributor is discussed under "Sales  Activities" and
     "Service  Activities."  Sometimes we do not pay compensation where tracking
     data  is not  available  for  certain  accounts  or  where  the  Authorized
     Institution  waives part of the  compensation.  In such  cases,  we may not
     require payment of any otherwise applicable CDSC.

     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 the Fund's Class A and Class C shares for
     activities which are primarily intended to result in the sale of such Class
     A and Class C shares,  respectively.  These activities include, but are not
     limited  to,  printing  of   prospectuses   and  statements  of  additional
     information and reports for other than existing  shareholders,  preparation
     and distribution of advertising and sales material,  expenses of organizing
     and  conducting  sales  seminars,   Additional  Concessions  to  Authorized
     Institutions,  the cost necessary to provide distribution-related  services
     or  personnel,  travel,  office  expenses,  equipment  and other  allocable
     overhead.

     Service   Activities.   We  may  pay  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.

8 Your Investment


<PAGE>

     By Exchange. Telephone the Fund at 800-821-5129 to request an exchange from
     any eligible Lord Abbett-sponsored fund.


REDEMPTIONS

     By Broker.  Call your investment  professional  for  instructions on how to
     redeem your shares.

     By  Telephone.  To obtain the proceeds of a  redemption  of $50,000 or less
     from  your  account,  you or your  representative  should  call the Fund at
     800-821-5129.

     By Mail.  Submit a written  redemption  request  indicating  the name(s) in
     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 sell.

     Include all necessary signatures. If the signer has any Legal Capacity, the
     signature and capacity must be guaranteed by an Eligible Guarantor. Certain
     other legal documentation may be required.  For more information  regarding
     proper documentation call 800-821-5129.

     Normally a check  will be mailed to the  name(s)  and  address in which the
     account is registered (or otherwise  according to your instruction)  within
     three business days after receipt of your redemption request.  Your account
     balance  must be  sufficient  to cover the amount  being  redeemed  or your
     redemption order will not be processed.  Under unusual  circumstances,  the
     Fund may suspend redemptions, or postpone payment for more than seven days,
     as permitted by federal securities laws.

     To determine if a CDSC applies to a  redemption,  see "Class A share CDSC,"
     "Class B share CDSC" or "Class C share CDSC."


DISTRIBUTIONS AND TAXES


     The Fund normally pays dividends from its net  investment  income  annually
     and distributes net capital gains (if any) as "capital gains distributions"
     annually.  Your  distributions  will be  reinvested  in the 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  is the  same  for  all
     shareholders  regardless of how long they have owned Fund shares or whether
     distributions are reinvested or paid in cash.

     Except in tax-advantaged accounts, any sale, redemption or exchange of Fund
     shares may be taxable to the shareholder.

     Information on the tax treatment of distributions,  including the source of
     dividends and distributions of capital gains by the Fund, will be mailed to
     shareholders  each year.  Because  everyone's tax situation is unique,  you
     should  consult your tax adviser  regarding the treatment of  distributions
     under the federal,  state and local tax rules that apply to you, as well as
     the tax  consequences  of gains or losses from the redemptions or exchanges
     of your shares.


Exchange  Limitations.  Exchanges should not be used to try to take advantage of
short-term swings in the market.  Frequent  exchanges create higher expenses for
the Fund.  Accordingly,  the Fund reserves the right to limit or terminate  this
privilege  for  any  shareholder   making  frequent  exchanges  or  abusing  the
privilege.  The Fund also may revoke the privilege for all shareholders  upon 60
days' written notice.

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

Eligible Guarantor is any broker or bank that is a member of the medallion stamp
program.  Most major securities  firms and banks are members of this program.  A
notary public is not an eligible guarantor.

     Lord Abbett is entitled to a management fee at an annual rate of .90% of 1%
     of the Fund's  average daily net assets.  The fee is calculated and payable
     monthly.  For the fiscal year ended  November 30, 1999,  Lord Abbett waived
     its management fee and subsidized a portion of the other expenses. The Fund
     pays all expenses not expressly assumed by Lord Abbett.

     Lord Abbett uses teams of portfolio  managers and analysts  acting together
     to manage the Fund's  investments.  Stephen  J.  McGruder,  Partner of Lord
     Abbett,  heads the Fund's team, the other senior member is Frederic D. Ohr.

     Abbett, Mr. McGruder served as Vice President of Wafra Investment  Advisory
     Group, a private  investment  advisory company,  from 1988 to 1995. Mr. Ohr

OTHER INVESTMENT TECHNIQUES

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

     Adjusting  Investment  Exposure.  The 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,  currency
     exchange contracts,  indexed securities,  and rights and warrants. The Fund
     may use these transactions to change the risk and return characteristics of
     its 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.


     Foreign Securities.  The Fund may invest up to 10% of its assets in foreign
     securities.  Foreign  markets  and the  securities  traded  in them are not
     subject  to the same  degree  of  regulation  as U.S.  markets.  Securities
     clearance and settlement  procedures may be different in foreign countries.
     There  may be less  trading  volume  in  foreign  markets,  subjecting  the
     securities traded in them to higher price  fluctuations.  Transaction costs
     may be higher in  foreign  markets.  The Fund may hold  foreign  securities
     which trade on days when the Fund does not sell  shares.  As a result,  the
     value of the Fund's portfolio securities may change on days an investor may
     not purchase or sell Fund shares.

     Foreign issuers are generally not subject to similar,  uniform  accounting,
     auditing and financial  reporting  requirements  as U.S.  issuers.  Foreign
     investments  may be  affected  by changes  in  currency  rates or  currency
     controls.  Certain  foreign  countries may limit a Fund's ability to remove
     its assets from the  country.  With respect to certain  foreign  countries,
     there is a possibility of  nationalization,  expropriation  or confiscatory
     taxation, imposition of withholding or other taxes, and political or social
     instability which could affect investments in those countries.

     Options Transactions.  The Fund may purchase and write put and call options
     on  securities  or stock  indices  that are traded on  national  securities
     exchanges.

     A put  option  gives the  buyer of the  option  the right to sell,  and the
     seller of the option  the  obligation  to buy,  the  underlying  instrument
     during the option  period.  The Fund may write only  covered put options to
     the extent  that cover for such  options  does not exceed 25% of the Fund's
     net  assets.  The Fund will not  purchase an option if, as a result of such
     purchase, more than 20% of its net assets would be invested in premiums for
     such options.

     A call  option  gives the  buyer of the  option  the right to buy,  and the
     writer  (seller)  of the  option the  obligation  to sell,  the  underlying
     instrument.  The Fund may write (sell) only "covered"  options.  This means
     that the Fund may only sell call options on securities which the Fund owns.
     When the Fund  writes a call option it gives up the  potential  for gain on
     the  underlying  securities  in excess of the exercise  price of the option
     during the period that the option is open.The  Fund may write  covered call
     options on  securities  having an aggregate  market not to exceed 5% of its
     assets.

     Risks of Options  Transactions.  Transactions in options involve additional
     risk of loss. Loss may result from a lack of correlation between changes in
     the value of these  derivative  instruments  and the  Fund's  assets  being
     hedged,   the  potential   illiquidity   of  the  markets  for   derivative
     instruments,  or the risks  arising  from margin  requirements  and related
     leverage  factors  associated  with  such  transactions.  The use of  these
     investment  techniques  also  involves  the  risk of loss if the  portfolio
     managers are incorrect in their  expectation of  fluctuations in securities
     prices. In addition,  the loss that may be incurred by the Fund in entering
     into  futures   contracts  and  in  writing  call  options  on  futures  is
     potentially unlimited and may exceed the amount of the premium received.


GLOSSARY OF SHADED TERMS

     Additional Concessions. Lord Abbett Distributor may, for specified periods,
     allow  dealers to retain the full sales charge for sales of shares,  or may
     pay an additional  concession to a dealer who sells a minimum dollar amount
     of our shares and/or shares of other Lord  Abbett-sponsored  funds. In some
     instances,  such  additional  concessions  will be offered  only to certain
     dealers expected to sell significant amounts of shares. Additional payments
     may  be  paid  from  Lord  Abbett   Distributor's  own  resources  or  from
     distribution  fees  received  from the 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 the 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  ex-changed 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 accounts 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 manda-tory distribution which bears the same relation to
     the entire mandatory  distribution as the Class 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 by an Eligible Guarantor.


                                                         For More Information 13


     Similarly,  if (for example) a redemption  request is 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 (see example in right column).

     Mutual Fund Fee Based Program.  Certain  unaffiliated  authorized  brokers,
     dealers,  registered  investment  advisers or other financial  institutions
     ("entities")   who  either  (1)  have  an  arrangement   with  Lord  Abbett
     Distributor in accordance  with certain  standards  approved by Lord Abbett
     Distributor,  providing  specifically  for  the  use  of  our  shares  (and
     sometimes providing for acceptance of orders for such shares on our behalf)
     in particular  investment  products made  available for a fee to clients of
     such entities,  or (2) 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:  (1)  an  individual;  (2) an
     individual  and his or her spouse and children under the age of 21; and (3)
     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.


RECENT PERFORMANCE


     The stock  market  rebounded  sharply  in the  fourth  quarter of 1999 with
     stocks of small- and mid-sized growth companies  asserting their leadership
     versus large company  growth  stocks.  Despite their strong fourth  quarter
     rally,   small-  and  mid-cap  stocks  remained   relatively   cheap  on  a
     price-to-earnings  basis,  often trading at a discount to large-cap stocks.
     In addition,  the average small- and mid-cap growth company  offered higher
     rates of  expected  earnings  growth than the  average  large-cap  company,
     confirming the opportunities that exist in this segment of the market.

     During 1999, we focused on increasing portfolio diversification both across
     and  within  sectors.   The  Fund's  investments  in  technology  companies
     continued to be significant  positive  contributors.  The Fund's technology
     holdings   included   companies   from   many   diverse   areas,   such  as
     telecommunications  services,  software  developers,  and select  equipment
     manufacturers.  We increased our emphasis on technology-related  companies,
     all of which turned out strong performances during the fourth quarter.  The
     ever-increasing demand for wireless communication services and products and
     increased  broadband access has benefited  several of the portfolio's major
     holdings.

     Stock  performance  for many  companies  in the  financial  and  healthcare
     services sectors continued to be  disappointing,  but the Fund was not hurt
     significantly,  as our  weightings  in these  sectors  has been  relatively
     moderate.  While  healthcare  services  companies  continued to suffer from
     government   and   managed    care-mandated   price   reductions,    select
     pharmaceutical  companies  entered into a new era of  profitability  as new
     products were introduced to the market.

          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.


Compliance with the investment restrictions in this Section  will be determined
at the time of purchase or sale of the portfolio investment.

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 Company 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  that are not
          listed  on the New  York  or  American  Stock  Exchange  or a  foreign
          exchange);

     (8)  invest in real estate  limited  partnership  interests or interests in
          oil,  gas or other  mineral  leases,  or  exploration  or  development
          programs,  except  that each Fund may invest in  securities  issued by
          companies  that engage in oil,  gas or other  mineral  exploration  or
          development activities;

     (9)   write,   purchase  or  sell  puts,  calls,   straddles,   spreads  or
           combinations   thereof,   except  to  the  extent  permitted  in  its
           Prospectuses and Statements of Additional Information, as they may be
           amended from time to time; or

     (10)  buy from or sell to any of its officers, directors, employees, or its
           investment  adviser or any of its  officers,  directors,  partners or
           employees, any securities other than shares.


Portfolio  Turnover.  For the fiscal year ended November 30, 1999, the portfolio
turnover rate was 60.59% for the Large-Cap  Series;  83.93% for Small-Cap  Value
Series; and 104.87% for Growth Opportunities Fund.

INVESTMENT TECHNIQUES


Each  Fund  intends  to use,  from time to time,  one or more of the  investment
techniques described below,  including lending portfolio securities,  repurchase
agreements,  warrants and covered call options.  While some of these  techniques
involve  risk when used  independently,  each Fund intends to use them to reduce
risk and volatility in its portfolios.

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. No more than 5% of each Fund's gross  assets may be invested in  closed-end
investment companies.

Call Options On Stock.  Each Fund may, from time to time,  write call options on
their  portfolio  securities.  Each Fund may write only call  options  which are
"covered,"  meaning  that a 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,  each  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 a Fund writes a call option,  the
purchaser of the option has the right to buy (and a Fund has the  obligation  to
sell) the underlying  security at the exercise price  throughout the term of the
option.  The  amount  paid  to a Fund  by the  purchaser  of the  option  is the
"premium."  Each Funds'  obligation to deliver the underlying  security  against
payment of the exercise  price would  terminate  either upon  expiration  of the
option or earlier if the a 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.  Each Fund does
not intend to write  covered call options  with  respect to  securities  with an
aggregate  market  value of more  than 5% of their  gross  assets at the time an
option is written.  This  percentage  limitation  will not be increased  without
prior disclosure in our current prospectus.

Each 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,  a Fund is
required to comply with the rules of The Options  Clearing  Corporation  and the
various  exchanges  with respect to collateral  requirements.  Each 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 a Fund for writing the option.

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


One reason for a Fund to write call  options is as part of a "sell  discipline."
If each 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, a 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,  each 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
investment  adviser,  the market price of a stock is overvalued and it should be
sold,  each  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 a 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, a Fund would, in effect,  have increased the selling
price of the stock. A 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.

<PAGE>


Debt  Securities.  Each  Fund may  invest  in bonds  or other  debt  securities.
However,  not more than 5% of its  assets  will be  invested  in high yield debt
securities.  High-yield 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.

Financial Futures Contracts.  The Large-Cap Series and the Growth  Opportunities
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 the Fund entering into the contract  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 clearinghouse 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.


Foreign  Currency  Hedging  Techniques.  The  Small-Cap  Value Series and Growth
Opportunities  Fund may also use foreign currency hedging  techniques.  Although
they do not normally engage in extensive currency hedging,  they may use forward
foreign  currency  contracts  and  options  thereon  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 a 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.  Under  some
circumstances,  a Fund may commit a substantial  portion of its portfolio to the
completion of forward  contracts. Although such contracts will be used primarily
to protect a Fund from adverse currency  movements,  their use involves the risk
that Lord Abbett will not accurately  predict  currency  movement,  and a Fund's
return could be reduced.


Foreign Currency Put And Call Options. The Small-Cap Value Series and the Growth
Opportunities  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.  The premiums paid for such
currency  put options  will not exceed 5% of the net assets of a Fund.  Unlisted
options, together with other illiquid securities,  are subject to a limit of 15%
of a Fund's net assets.  The face value of such currency call option  writing or
cross-hedging  may not exceed 90% of the value of the securities  denominated in
such currency, and invested in to cover such call writing or to be crossed.

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.



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.  The  Small-Cap  Value  Series  and  the  Growth
Opportunities  Fund expect to enter into forward foreign  currency  contracts in
primarily two circumstances.  First, when either 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 the investment adviser 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 regular basis.

Illiquid  Securities.  Each  Fund  may  invest  in  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 Fund may invest up to 15% of its
assets in illiquid securities.


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.

Limitations  On The  Purchases  And  Sales Of Stock  Options,  Options  On Stock
Indices And Stock Index  Futures.  The Small-Cap  Value Series 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 Series is obligated as a writer. The Fund
will not (a) write puts having an aggregate  exercise  price greater than 25% of
its 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.

Options And Financial Futures Transactions.  The Large-Cap Series and the Growth
Opportunities  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 the
investment  adviser 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. 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.

Put  Options On Stock.  The  Small-Cap  Value  Series 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 Series has cash or other reserves  available for investment
as a result of sales of Fund shares or, more importantly, because the investment
adviser believes a more defensive and less fully invested  position is desirable
in light of market  conditions.  If the investment  adviser 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 Series 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 Series 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 Series 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.

The Small-Cap Value Series may only write covered put options to the extent that
cover for such  options  does not exceed 25% of its net  assets.  The  Small-Cap
Value Series will not purchase an option if, as a result of such purchase,  more
than 20% of its total assets would be invested in premiums for such options.


Repurchase  Agreements.  Each Fund may enter  into  repurchase  agreements  with
respect to a security.  A repurchase  agreement is a  transaction  by which a
Fund acquires a security and  simultaneously  commits to resell that security to
the seller (a bank or  securities  dealer) at an agreed  upon price on an agreed
upon date.  The resale price  reflects  the  purchase  price plus an agreed upon
market  rate of  interest  which  is  unrelated  to the  coupon  rate or date of
maturity of the purchased security. In this type of transaction,  the securities
purchased  by each  Fund  have a total  value  in  excess  of the  value  of the
repurchase  agreement.  Each  Fund  requires  at all times  that the  repurchase
agreement be collateralized by cash or U.S. Government securities having a value
equal  to,  or in  excess  of,  the  value  of the  repurchase  agreement.  Such
agreements  permit  each Fund to keep all of its assets at work while  retaining
flexibility in pursuit of investments of a longer term nature.



                                       7


<PAGE>


The use of repurchase  agreements  involves certain risks.  For example,  if the
seller of the agreement  defaults on its obligation to repurchase the underlying
securities at a time when the value of these  securities has declined,  the Fund
may incur a loss  upon  disposition  of them.  If the  seller  of the  agreement
becomes  insolvent  and  subject  to  liquidation  or  reorganization  under the
Bankruptcy  Code or other  laws,  a  bankruptcy  court  may  determine  that the
underlying  securities are collateral not within the control of the Fund and are
therefore  subject  to  sale by the  trustee  in  bankruptcy.  Even  though  the
repurchase  agreements may have  maturities of seven days or less, they may lack
liquidity,  especially if the issuer encounters  financial  difficulties.  While
Fund  management  acknowledges  these  risks,  it is  expected  that they can be
controlled   through  stringent   selection   criteria  and  careful  monitoring
procedures.   Fund  management   intends  to  limit  repurchase   agreements  to
transactions with dealers and financial institutions believed by Fund management
to present minimal credit risks.  Fund management will monitor  creditworthiness
of the repurchase agreement sellers on an ongoing basis.

Rights  And  Warrants.  Each  Fund may  invest in rights  and  warrants  to
purchase  securities,  including  warrants  which are not  listed on the NYSE or
American Stock Exchange in an amount not to exceed 5% of the value of the Fund's
gross  assets.  Each Fund will not invest more than 5% of its assets in warrants
and not more than 2% of such  value in  warrants  not  listed on the New York or
American Stock Exchanges, except when they form a unit with other securities. As
a matter of operating  policy, each Fund will not invest more than 5% of its net
assets in rights.

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.


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  Series 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  Series,  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 Series'  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
Series'  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 Series
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 Series 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  Series.  It is the
Small-Cap  Value  Series'  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
Series will not purchase or sell any index option  contract unless and until, in
the investment adviser'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.


Rule 144A Securities.  Each Fund may invest in Rule 144A  securities,  which are
securities  determined  by the Board to be liquid  pursuant  to  Securities  and
Exchange  Commission  Rule 144A (the  "Rule").  Under  the  Rule,  a  qualifying
unregistered  security may be resold to a qualified  institutional buyer without
registration and without regard to whether the seller  originally  purchased the
security for  investment.  A  substantial  part of the  lower-rated  debt market
consists  of Rule 144A  securities,  many of which are  registered  within a few
month  of  their  purchases.  Investments  in  Rule  144A  securities  initially
determined  to be liquid  could  have the effect of  diminishing  the level of a
Fund's liquidity during period of decreased market interest in such securities.


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, the Large-Cap Series and the Growth  Opportunities 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.

Segregated  Accounts.  If the Small-Cap Value Series 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 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 Series has
not written a stock call  option and which has not been hedged by the  Small-Cap
Value Series by the sale of stock index futures.  Such  securities  will include
stocks which  represent at least 50% of the  weighting of the industry or market
segment  index and will  represent at least 50% of the  Small-Cap  Value Series'
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 Series
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 Series 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 Series' 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 Series
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  Series  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  described in this  paragraph.  In instances  involving the
purchase of stock index  futures  contracts by the Small-Cap  Value  Series,  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  Series'  commodity  futures or commodity
options  transactions  constitute  bona fide  hedging  transactions  within  the
meaning of the CFTC's  regulations.  The  Small-Cap  Value Series will use stock
index futures and options on futures as described herein in a manner  consistent
with this requirement.


Short Sales.  The  Small-Cap  Value Series may make short sales of securities or
maintain a short  position,  provided that at all times when a short position is
open the Fund owns an equal amount of such securities or securities  convertible
into or exchangeable, without payment of any further consideration, for an equal
amount of the  securities of the same issuer as the securities  sold short.  The
Small-Cap  Value  Series  does not intend to have more than 5% of its net assets
(determined  at the time of the short sale)  subject to short sales  against the
box.


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
Series 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  Series'  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 Series 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 Series has other liquid assets that are sufficient to
satisfy the exercise of a call, the Small-Cap  Value Series 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 Series  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 Series 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 Series is able to sell stocks in its  portfolio.  As with stock
options, the Small-Cap Value Series will not learn that an index option has been
exercised  until the day following the exercise date but, unlike a call on stock
where  the  Small-Cap  Value  Series  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 Series has
written is  "covered" by an index call held by the  Small-Cap  Value Series with
the same strike price,  the  Small-Cap  Value Series 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 Series  exercises the call it holds or the time
the  Small-Cap  Value  Series 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
Series 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  Series  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.

Stock Index Futures.  The Small-Cap  Value Series 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
Series' 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 Series' net assets.

Stock Index Options.  Except as describe below,  the Small-Cap Value Series 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 Series 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.


When-Issued or Delayed Delivery  Securities.  The Small-Cap Value Series and the
Growth  Opportunities  Fund may  purchase or sell  securities  with  payment and
delivery taking place as much as a month or more later.  The Fund may do this in
an effort to buy or sell the securities at an advantageous  price or 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 the Fund commits a significant  amount of assets to when-issued
or delayed  delivery  transactions,  it may increase the  volatility  of its net
asset value.

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

     The amounts of the aggregate  compensation  payable by the Large-Cap Series
as of November 30, 1999 deemed invested in Company shares,  including  dividends
reinvested and changes in net asset value applicable to such deemed investments,
were: Mr.  Bigelow,  $1,062;  Mr. Calhoun,  $626; Mr. Dixon,  $509; Mr. Jansing,
$852; Mr. MacDonald,  $462; Mr. Millican,  $1,474;  Mr. Bush, $23; and Mr. Neff,
$1,187.  If the amounts  deemed  invested  in Company  shares were added to each
director's actual holdings of Company shares as of November 30, 1999, each would
own,  the  following:  Mr.  Bigelow,  $1,062;  Mr.  Calhoun,  $626;  Mr.  Dixon,
$3,928.74; Mr. Jansing,  $37,014.10;  Mr. MacDonald, $462; Mr. Millican, $1,474;
Mr. Bush, $23; and Mr. Neff, $1,187.

     The  amounts  of  the   aggregate   compensation   payable  by  the  Growth
Opportunities  Fund as of November 30, 1999 deemed  invested in Company  shares,
including dividends reinvested and changes in net asset value applicable to such
deemed investments, were: Mr. Bigelow, $32; Mr. Calhoun, $31; Mr. Dixon, $0; Mr.
Jansing, $30; Mr. MacDonald,  $0; Mr. Millican,  $31; and Mr. Neff, $310. If the
amounts deemed invested in Company shares were added to each  director's  actual
holdings  of Company  shares as of  November  30,  1999,  each  would  own,  the
following:  Mr.  Bigelow,  $32; Mr.  Calhoun,  $31 Mr. Dixon,  $0; Mr.  Jansing,
$14,958.72; Mr. MacDonald, $0; Mr. Millican, $31; and Mr. Neff, $310.

     The amounts of the aggregate  compensation  payable by the Small-Cap  Value
Series as of  November  30, 1999 deemed  invested in Company  shares,  including
dividends  reinvested  and changes in net asset value  applicable to such deemed
investments,  were: Mr. Bigelow,  $3,090; Mr. Calhoun,  $2,084; Mr. Dixon, $158;
Mr. Jansing, $2,503; Mr. MacDonald,  $482; Mr. Millican,  $2,713; Mr. Bush, $82;
and Mr. Neff,  $2,713.  If the amounts  deemed  invested in Company  shares were
added to each  director's  actual  holdings of Company shares as of November 30,
1999, each would own, the following:  Mr. Bigelow,  $3,090; Mr. Calhoun, $2,084;
Mr. Dixon, $158; Mr. Jansing, $2,503; Mr. MacDonald, $482; Mr. Millican, $2,713;
Mr. Bush, $82; and Mr. Neff, $2,713.

     directors'/trustees'  fees and  attendance  fees for  board  and  committee
     meetings,  of a nature  referred  to in footnote  one,  accrued by the Lord
     Abbett-sponsored  funds during the year ended December 31, 1999,  including
     fees  directors/trustees have chosen to defer, but does not include amounts
     accrued under the equity-based plans and shown in Column 3.

4.   The equity-based plans superseded a previously approved retirement plan for
     all  directors/trustees.  Directors had the option to convert their accrued
     benefits  under  the  retirement  plan.  All of the  then  current  outside
     directors/trustees  except one made such  election.  Mr.  Jansing  chose to
     continue to receive  benefits under the retirement plan which provides that
     outside  directors  (trustees) may receive annual  retirement  benefits for
     life equal to their final annual retainer following  retirement at or after
     age 72 with at least ten years of service.  Thus,  if Mr.  Jansing  were to
     retire and the annual retainer  payable by the funds were the same as it is
     today, he would receive annual retirement benefits of $50,000.

                             Portfolio Transactions


The  Company's  policy  is  to  obtain  best  execution  on  all  our  portfolio
transactions, which means that it seeks 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, each Fund may pay, as described below,
a higher 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 the  Company  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.



                                       16


<PAGE>

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
Funds; 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 Funds,  and not all of such  services  will  necessarily  be used by Lord
Abbett in connection with their advisory  services to such other  accounts.  The
Funds 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.  When, in the opinion of the investment adviser,  two or
more brokers (either  directly or through their  correspondent  clearing agents)
are in a  position  to obtain the best price and  execution,  preference  may be
given to brokers who have sold shares of a Fund or who have provided  investment
research, statistical, or other related services to the investment adviser.

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
the same securities as described above. If these clients wish to buy or sell the
same  security  as we do,  they may have their  transactions  executed  at times
different from our transactions and thus may not receive the same price or incur
the same commission cost as a Lord Abbett-sponsored fund does.


For the  fiscal  years  ended  November  30,  1997,  1998 and 1999 we paid total
commissions to  independent  broker-dealers  of $88,234,  $321,279 and $395,908
for the Large-Cap Series, respectively.  For the fiscal years ended November 30,
1997, 1998, and 1999, we paid total commissions to independent broker-dealers of
$1,812,425, $1,564,340 and $1,492,501, respectively, for the Small-Cap Value
Series. For the fiscal years ended November 30, 1997, 1998, and 1999,  we paid
total commissions to  independent broker-dealers of $3,687, $12,741 and $91,960
for the Growth Opportunities Fund, respectively.

                            And Shareholder Services

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.


For each class of shares the net asset  value will be  determined  by taking the
net asset value and dividing by the shares outstanding).

The maximum offering price of Class A shares of each Fund on November 30, 1999
was computed as follows:

The Company on behalf of the Funds has  entered  into a  distribution  agreement
with 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.

Alternative Sales Arrangements

Classes of Shares. The Funds offer investors four different classes of shares in
this  Statement  of  Additional  Information.  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,
unless your purchase meets one of the following conditions: (i) your purchase is
for $1  million  or more in one or more Lord  Abbett-sponsored  funds;  (ii) you
purchase  through an  employer-sponsored  retirement plan (a "Retirement  Plan")
with at least 100  eligible  employees  under the  Internal  Revenue Code (which
excludes  Individual  Retirement  Accounts);  or (iii)  you  purchase  through a
"special  retirement  program"  which is a certain type program  sponsored by an
institution or other entity  permitted to receive  service  and/or  distribution
fees under a Rule 12b-1 Plan (an  "Authorized  Institution").  The program  must
also have one or more characteristics  distinquishing it, in the opinion of Lord
Abbett Distributor,  from a Mutual Fund Fee Based 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.
However,  if you meet a condition  which  allows you to purchase  Class A shares
without an initial  sales  charge,  but you redeem any of those shares within 24
months  after the month in which  you buy  them,  you pay the Fund a  contingent
deferred  sales  charge  ("CDSC") of 1%.  There is an  exception to the CDSC 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 the sections below.

<PAGE>


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 the sections below.

Class C Shares.  If you buy Class C shares,  you pay no sales charge at the time
of  purchase,  but if you redeem your  shares  before the first  anniversary  of
buying  them,  you will  normally  pay 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 the sections below.

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 the section  below.  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 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.


                                       20


<PAGE>

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 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.

Rule 12b-1 Plans

Class A, B, C, and P. 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. 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.


                                       21


<PAGE>


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, 1999, the fees paid to
dealers under the A Plan for the Large-Cap Series was $459,880; for  the  Growth
Opportunities Fund $45,762; and for the Small-Cap Value Series $676,312.

For the fiscal year ended November 30, 1999, the fee paid to dealers under the B
Plan for the Large-Cap Series was $534,727; for the Growth Opportunities Fund
$23,804; and for the Small-Cap Value Series $1,733,727.

For the fiscal year ended November 30, 1999, the fee paid to dealers under the C
Plan for the Large-Cap Series was $123,491; for the Growth  Opportunities Fund
$18,664; and for the Small-Cap Value Series $528,749.


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

<PAGE>

In the table, an  "anniversary" is the same calendar day in each respective year
after the date of purchase.  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,  subject to certain exceptions,  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. With respect to Class A shares
purchased pursuant to a special  retirement wrap program,  no CDSC is payable on
redemptions  which continue as investments in another fund  participating in the
program.  With respect to Class B shares, no CDSC is payable for redemptions (i)
in connection with Systematic Withdrawal Plan and Div-Move services as described
below under those headings, (ii) in connection with mandatory distribution under
403(b) plans and IRAs and (iii) in connection with death of the shareholder.  In
the case of Class A and Class C shares,  the CDSC is received by the  applicable
Fund and is  intended  to  reimburse  all or a portion of the amount paid by the
Fund if the  shares  are  redeemed  before  the Fund has had an  opportunity  to
realize the anticipated  benefits of having a long-term  shareholder  account in
the Fund.  In the case of Class B shares,  the CDSC is  received  by Lord Abbett
Distributor   and  is  intended  to   reimburse   its   expenses  of   providing
distribution-related service to the 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 that 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.


                                       23


<PAGE>

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 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,  and Lord
Abbett Equity Fund ("LAEF") which is not issuing shares.  The exchange privilege
will not be available with respect to any otherwise  "Eligible Funds" the shares
of which are not available to new investors of the type requesting the exchange.


Letter of Intention. Under the terms of the Letter of Intention, as described in
the Prospectus,  you may invest $50,000 or more over a 13-month period in 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). Shares 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 Letter is not
completed.  The Letter 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 retired  directors/trustees  and employees and other family
members thereof.



                                       24


<PAGE>

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 advisory 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 advisory program.  Such characteristics  include,
among other things, the fact that an authorized  institution does not charge its
clients  any  fee of a  consulting  or  advisory  nature  that  is  economically
equivalent  to the  distribution  fee under 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 the Funds to carry out the order.  The  signature(s)
and any legal  capacity  of the  signer(s)  must be  guaranteed  by an  Eligible
Guarantor,  which is any broker or bank that is a member of the medallion  stamp
program. 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 on redemptions of up to 12% per
year of the  current  net  asset  value of your  account  at the time the SWP is
established.  For Class B shares  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,  excluding 401(k) 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.


                                       6.
                                Past Performance


Each Fund computes 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  (as  described  in the  next
paragraph)  from the initial  amount  invested  and  reinvestment  of all income
dividends and capital gains distributions on the reinvestment dates at net asset
value.  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.

Using the computation described above, the following table indicates the average
annual  compounded rates of total return for each Fund, per class, for one year,
five years, ten years, or since inception where applicable.  Past performance is
not indicative of future results.

Each Fund's yield  quotation for each class is based on a 30-day period ended on
a specified  date,  computed by dividing such Fund's net  investment  income per
share earned during the period by such Fund's  maximum  offering price per share
on the last day of the  period.  This is  determined  by finding  the  following
quotient:  take the class' dividends and interest earned during the period 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 Fund's 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 Fund's net asset value per share.  Yields for
Class B and Class 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


Each Fund  intends  to elect  and to  qualify  for  special  tax  treatment
afforded regulated  investment companies under the Internal Revenue Code of 1986
(the "Code").  If it so qualifies,  each Fund (but not its shareholders) will be
relieved of federal  income taxes on the amount it timely  distributes to share-
holders.  If in  any  taxable  year a  Fund  does  not  qualify  as a  regulated
investment  company,  all of its  taxable  income  will be  taxed to the Fund at
regular corporate rates.

Each Fund contemplates declaring as dividends  substantially all of its net
investment  income.  Dividends  paid by a Fund from its  investment  income  and
distributions  of its net realized  long-term  capital  gains are taxable to its
shareholders  as ordinary income and capital gains,  respectively,  whether such
dividendeds  or  distributions  are received in cash or reinvested in additional
shares of the Fund.  Each Fund  will send its  shareholders  annual  information
concerning the tax treatment of dividends and other distributions.

Upon a sale, exchange or  redemption  of shares of a Fund,  a  shareholder  will
recognize  short-  or  long-term  capital  gain  or  loss,  depending  upon  the
shareholder's  holding period in the Fund's shares.  However, if a shareholder's
holding  period in his shares is six month or less,  any capital  loss  realized
from a sale or exchange of such shares must be treated as long-term capital loss
to the extent of dividends classified as "capital gains dividends" received with
respect to such shares.  The maximum tax rates  applicable  to net capital gains
recognized by individuals and other non-corporate  taxpayers are (i) the same as
ordinary  income rates for capital assets held for one year or less and (ii) 20%
for  capital  assets  held  for more  than one  year.  Capital  gains or  losses
recognized by corporate  shareholders  are subject to tax at the ordinary income
tax rates applicable to corporations.



                                       27

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.

Some  shareholders  may  be  subject  to a 31%  withholding  tax  on  reportable
dividends,   capital  gains   distributions  and  redemption  payments  ("backup
withholding").  Generally,  shareholders  subject to backup  withholding will be
those for whom a certified  taxpayer  identification  number is not on file with
the Fund or who, to the Fund's  knowledge,  have furnished an incorrect  number.
When  establishing  an account,  an investor  must  certify  under  penalties of
perjury that such number is correct and that he or she is not otherwise  subject
to backup withholding.

The writing of call options and other investment  techniques and practices which
the Funds 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 the Funds,  which is taxed as  ordinary  income when
distributed to shareholders.

The Funds may be subject to foreign  withholding  taxes,  which would reduce the
yield on their investments. It is generally expected that Fund  shareholders who
are subject to United States  federal income tax will not be entitled to claim a
federal income tax credit or deduction for foreign income taxes paid by a Fund.

Each Fund 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.  Each Fund intends to  distribute to  shareholders  each year an
amount adequate to avoid the imposition of such excise tax.

Dividends paid by a Fund will qualify for the dividends-received  deduction
for  corporations to the extent they are derived from dividends paid by domestic
corporations.  Corporate  shareholders must have held their shares in a Fund for
more than 45 days to qualify for the deduction on dividends paid by the Fund.

Gain and loss  realized by a Fund 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
gain and will be reduced by the net  amount,  if any, of such  foreign  exchange
loss.

If a Fund purchases  shares in certain foreign  investment  entities called
"passive foreign investment companies," the Fund 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 Fund to its  shareholders.  Additional  charges in the nature of
interest  may be imposed on the Fund in respect of deferred  taxes  arising from
such distributions or gains. If a Fund were to make a "qualified  electing fund"
election with respect to its investment in a passive foreign investment company,
in lieu of the foregoing requirements, such Fund might be required to include in
income each year a portion of the ordinary earnings and net capital gains of the
passive foreign investment company,  even if such amount were not distributed to
such Fund.  Alternatively,  if a Fund were to make a  "mark-to-market"  election
with respect to its investment in a passive foreign investment company,  gain or
loss with respect to the investment  would be considered  realized at the end of
each taxable year of the Fund even if the Fund continued to hold the investment,
and would be treated as ordinary income or loss to the Fund.

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 a
Fund,  including the applicable rate of U.S. withholding  tax on dividends
representing ordinary income and net short-term capital gains, and the
applicability of U.S. gift and estate taxes.

                          Information About the Company

The directors,  trustees and officers of Lord  Abbett-sponsored  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  Company'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  fund  to the  extent
contemplated by the recommendations of such Advisory Group.


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.

                  foregoing  provisions,  or otherwise,  the Registrant has been
                  advised  that in the opinion of the  Securities  and  Exchange
                  Commission  such  indemnification  is against public policy as
                  expressed in the Act and is, therefore,  unenforceable. In the
                  event   that  a  claim  for   indemnification   against   such
                  liabilities  (other  than the  payment  by the  Registrant  of
                  expense incurred or paid by a Director, officer or controlling
                  person of the  Registrant  in the  successful  defense  of any
                  action,  suit or  proceeding)  is asserted  by such  Director,
                  officer  or   controlling   person  in  connection   with  the
                  securities being  registered,  the Registrant will,  unless in
                  the  opinion of its  counsel  the  matter has been  settled by
                  controlling  precedent,  submit  to  a  court  of  appropriate
                  jurisdiction the question 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 Directors' and officers'
                  errors and omissions  liability  insurance  policy  protecting
                  Directors and officers  against  liability for breach of duty,
                  negligent act,  error or omission  committed in their capacity
                  as  Trustees  or  officers.   The  policy   contains   certain
                  exclusions,  among which is exclusion from coverage for active
                  or deliberate  dishonest or fraudulent  acts and exclusion for
                  fines or  penalties  imposed  by law or other  matters  deemed
                  uninsurable.

Lord Abbett Research Fund, Inc.

Dear Sirs:

     You have requested our opinion in connection  with your filing of Amendment
No. 27 to the Registration  Statement on Form N-1A (the  "Amendment")  under the
Investment Company Act of 1940, as amended,  of Lord Abbett Research Fund, Inc.,
a  Maryland  corporation  (the  "Company"),  and in  connection  therewith  your
registration of the following shares of capital stock, with a par value of $.001
each,  of  the  Company  (collectively,   the  "Shares"):   Lord  Abbett  Growth
Opportunities  Fund (Classes A, B, C, and P); Small-Cap Value Series (Classes A,
B, C, and P); and Large-Cap Series (Classes A, B, C, and P).

     We have  examined  and relied upon  originals,  or copies  certified to our
satisfaction,  of  such  company  records,  documents,  certificates  and  other
instruments  as in our judgment are  necessary  or  appropriate  to enable us to
render the opinion set forth below.

     We are of the opinion  that the Shares  issued in the  continuous  offering
have been duly authorized  and,  assuming the issuance of the Shares for cash at
net asset value and receipt by the Company of the consideration  therefor as set
forth in the  Amendment and that the number of shares issued does not exceed the
number  authorized,   the  Shares  will  be  validly  issued,   fully  paid  and
nonassessable.

     We express no  opinion  as to matters  governed  by any laws other than the
Title 2 of the Maryland Code. We consent to the filing of this opinion solely in
connection  with the Amendment.  In giving such consent,  we do not hereby admit
that we come within the  category  of persons  whose  consent is required  under
Section  7 of  the  Securities  Act of  1933,  as  amended,  or  the  rules  and
regulations of the Securities and Exchange Commission thereunder.

LORD, ABBETT & CO.
LORD ABBETT-SPONSORED FUNDS
AND
LORD ABBETT DISTRIBUTOR LLC

CODE OF ETHICS


I.      Statement of General Principles

     The personal  investment  activities of any officer,  director,  trustee or
employee  of the Lord  Abbett-sponsored  Funds  (the  Funds) or any  partner  or
employee of Lord,  Abbett & Co. (Lord  Abbett) will be governed by the following
general principles:  (1) Covered Persons have a duty at all times to place first
the interests of Fund shareholders and, in the case of employees and partners of
Lord Abbett,  beneficiaries of managed accounts; (2) all securities transactions
by Covered  Persons shall be conducted  consistent  with this Code and in such a
manner as to avoid any actual or potential  conflict of interest or any abuse of
an individual's  position of trust and  responsibility;  and (3) Covered Persons
should not take  inappropriate  advantage of their positions with Lord Abbett or
the Funds.

II.     Specific Prohibitions

     No person covered by this Code,  shall purchase or sell a security,  except
an Excepted Security, if there has been a determination to purchase or sell such
security for a Fund (or, in the case of any employee or partner of Lord, Abbett,
for  another  client of Lord  Abbett),  or if such a  purchase  or sale is under
consideration  for a Fund (or,  in the case of an  employee  or  partner of Lord
Abbett,  for  another  client  of Lord  Abbett),  nor may such  person  have any
dealings in a security that he may not purchase or sell for any other account in
which he has Beneficial Ownership,  or disclose the information to anyone, until
such  purchase,  sale or  contemplated  action  has  either  been  completed  or
abandoned.

III.    Obtaining Advance Approval

     Except  as  provided  in  Sections  V and VI of  this  Code,  all  proposed
transactions  in securities  (privately or publicly  owned) by Covered  Persons,
except transactions in Excepted  Securities,  should be approved consistent with
the provisions of this Code in advance by one of the partners of Lord Abbett. In
order to obtain approval,  the Covered Person must send their request via e-mail
to  Isabel  Herrera,  or in her  absence,  Chrissy  DeCicco,  who will  obtain a
partner's approval. After approval has been obtained, the Covered Person may act
on it  within  the next  seven  business  days,  unless  he  sooner  learns of a
contemplated  action by Lord  Abbett.  After the seven  business  days,  or upon
hearing of such contemplated action, a new approval must be obtained.

     Furthermore, in addition to the above requirements,  partners and employees
directly involved must disclose information they may have concerning  securities
they  may  want to  purchase  or sell to any  portfolio  manager  who  might  be
interested in the securities for the portfolios they manage.

IV.   Reporting and Certification Requirements; Brokerage Confirmations

(1)  Except  as  provided  in  Sections  V and VI of this  Code,  within 10 days
     following  the end of each calendar  quarter each Covered  Person must file
     with Ms. Herrera a signed  Security  Transaction  Reporting  Form. The form
     must be signed and filed whether or not any security  transaction  has been
     effected.  If any  transaction has been effected during the quarter for the
     Covered  Person's  account  or for any  account in which he has a direct or
     indirect  Beneficial  Ownership,  it must be reported.  Excepted  from this
     reporting  requirement are transactions effected in any accounts over which
     the  Covered  Person has no direct or  indirect  influence  or control  and
     transactions  in  Excepted  Securities.  Ms.  Herrera  is  responsible  for
     reviewing these transactions promptly and must bring any apparent violation
     to the attention of the General Counsel of Lord Abbett.

(2)  Each  employee  and  partner  of Lord  Abbett  will  upon  commencement  of
     employment  and  annually   thereafter  disclose  all  personal  securities
     holdings and annually  certify that: (i) they have read and understand this
     Code and  recognize  they are subject  hereto;  and (ii) they have complied
     with the requirements of this Code and disclosed or reported all securities
     transactions   required  to  be  disclosed  or  reported  pursuant  to  the
     requirements of this Code.

(3)  Each employee and partner of Lord Abbett will direct his brokerage  firm to
     send copies of all confirmations and all monthly statements directly to Ms.
     Herrera.

(4)  Each  employee  and  partner of Lord  Abbett who has a  Fully-Discretionary
     Account (as  defined in Section  VI) shall  disclose  all  pertinent  facts
     regarding such Account to Lord Abbett's  General Counsel upon  commencement
     of  employment.  Each such  employee or partner shall  thereafter  annually
     certify on the prescribed form that he or she has not and will not exercise
     any direct or indirect influence or control over such Account,  and has not
     discussed  any  potential   investment   decisions  with  such  independent
     fiduciary in advance of any such transactions.

V. Special Provisions Applicable to Outside Directors and Trustees of theFunds

The primary function of the Outside  Directors and Trustees of the Funds is
to set policy and monitor the management  performance of the Funds' officers and
employees  and the  partners  and  employees  of  Lord  Abbett  involved  in the
management of the Funds. Although they receive complete information as to actual
portfolio  transactions,  Outside  Directors  and Trustees are not given advance
information as to the Funds' contemplated investment transactions.

An Outside  Director or Trustee  wishing to  purchase or sell any  security
will  therefore  generally  not be  required to obtain  advance  approval of his
security  transactions.  If,  however,  during  discussions at Board meetings or
otherwise an Outside  Director or Trustee  should learn in advance of the Funds'
current or  contemplated  investment  transactions,  then  advance  approval  of
transactions  in the  securities  of such  company(ies)  shall be required for a
period of 30 days from the date of such Board meeting.  In addition,  an Outside
Director or Trustee can  voluntarily  obtain  advance  approval of any  security
transaction or transactions at any time.

No report  described  in  Section  IV (1) will be  required  of an  Outside
Director or Trustee unless he knew, or in the ordinary  course of fulfilling his
official  duties as a director or trustee should have known,  at the time of his
transaction,  that during the 15-day period immediately before or after the date
of the transaction (i.e., a total of 30 days) by the Outside Director or Trustee
such  security  was or was to be purchased or sold by any of the Funds or such a
purchase  or  sale  was or was to be  considered  by a  Fund.  If he  makes  any
transaction requiring such a report, he must report all securities  transactions
effected during the quarter for his account or for any account in which he has a
direct or  indirect  Beneficial  Ownership  interest  and over  which he has any
direct or indirect influence or control.  Each Outside Director and Trustee will
direct his  brokerage  firm to send copies of all  confirmations  of  securities
transactions to Ms. Herrera, and annually make the certification  required under
Section  IV(2)(i) and (ii).  Outside  Directors' and Trustees'  transactions  in
Excepted Securities are excepted from the provisions of this Code.

It shall be prohibited  for an Outside  Director or Trustee to (i) trade on
material  non-public  information,  or (ii)  trade in  options  with  respect to
securities covered by this Code without advance approval from Lord Abbett. Prior
to accepting an appointment as a director of any company, an Outside Director or
Trustee will advise Lord Abbett and discuss with Lord Abbett's  Managing Partner
whether  accepting  such  appointment  creates any conflict of interest or other
issues.

If an Outside Director or Trustee,  who is a director or an employee of, or
consultant to, a company,  receives a grant of options to purchase securities in
that company (or an  affiliate),  neither the receipt of such  options,  nor the
exercise of those options and the receipt of the underlying  security,  requires
advance approval from Lord Abbett. Further, neither the receipt nor the exercise
of such options and receipt of the  underlying  security is  reportable  by such
Outside  Director or Trustee.  Finally,  neither the receipt nor the exercise of
such options shall be considered  "trading in options" within the meaning of the
preceding paragraph of this Section V.



VI.  Additional Requirements relating to Partners and Employees of Lord Abbett

It shall be prohibited for any partner or employee of Lord Abbett:

(1)  To obtain or accept favors or preferential treatment of any kind or gift or
     other thing having a value of more than $100 from any person or entity that
     does business with or on behalf of the investment  company---no  partner or
     employee shall have any ownership interest in a brokerage firm;

(2)  to trade on material  non-public  information  or otherwise  fail to comply
     with the Firm's  Statement of Policy and  Procedures  on Receipt and Use of
     Inside  Information  adopted  pursuant to Section  15(f) of the  Securities
     Exchange  Act of 1934 and Section  204A of the  Investment  Advisers Act of
     1940;

(3)  to trade in options with respect to securities covered under this Code;

(4)  to profit in the purchase and sale, or sale and  purchase,  of the same (or
     equivalent)  securities  within 60 calendar  days (any profits  realized on
     such  short-term  trades shall be disgorged to the  appropriate  Fund or as
     otherwise determined);

(5)  to  trade  in  futures  or  options  on  commodities,  currencies  or other
     financial  instruments,  although the Firm  reserves the right to make rare
     exceptions in unusual circumstances which have been approved by the Firm in
     advance;

(6)  to engage in short sales or purchase securities on margin;

(7)  to buy or sell any security  within seven business days before or after any
     Fund (or other Lord Abbett  client)  trades in that  security  (any profits
     realized on trades within the proscribed  periods shall be disgorged to the
     Fund (or the other client) or as otherwise determined);

(8)  to subscribe to new or secondary public offerings, even though the offering
     is not one in  which  the  Funds or Lord  Abbett's  advisory  accounts  are
     interested;

(9)  to become a director of any company  without the Firm's  prior  consent and
     implementation of appropriate safeguards against conflicts of interest.

In  connection  with any request for  approval,  pursuant to Section III of
this Code,  of an  acquisition  by partners or  employees  of Lord Abbett of any
securities in a private placement,  prior approval will take into account, among
other factors,  whether the investment opportunity should be reserved for any of
the Funds and their  shareholders  (or other clients of Lord Abbett) and whether
the opportunity is being offered to the individual by virtue of the individual's
position  with  Lord  Abbett  or  the  Funds.  An  individual's   investment  in
privately-placed  securities  will be disclosed to the Managing  Partner of Lord
Abbett if such  individual  is involved in  consideration  of an investment by a
Fund (or other client) in the issuer of such securities.  In such circumstances,
the Fund's (or other  client's)  decision to purchase  securities  of the issuer
will be subject to independent  review by personnel with no personal interest in
the issuer.

If a spouse of a partner or employee of Lord Abbett who is a director or an
employee  of, or a  consultant  to, a  company,  receives  a grant of options to
purchase  securities in that company (or an affiliate),  neither the receipt nor
the exercise of those  options  requires  advance  approval  from Lord Abbett or
reporting.  Any subsequent sale of the security  acquired by the option exercise
by that spouse would require advance approval and is a reportable transaction.

Advance  approval  is not  required  for  transactions  in any account of a
Covered  person if the  Covered  Person has no direct or indirect  influence  or
control ( a  "Fully-Discretionary  Account"). A Covered person will be deemed to
have "no direct or indirect  influence or control" over an account only if : (i)
investment  discretion  for the account  has been  delegated  to an  independent
fiduciary and such investment  discretion is not shared with the employee,  (ii)
the  Covered  Person  certifies  in writing  that he or she has not and will not
discuss any  potential  investment  decisions  with such  independent  fiduciary
before  any  transaction  and (iii)  the  General  Counsel  of Lord  Abbett  has
determined  that  the  account  satisfies  these  requirements.  Transaction  in
Fully-Discretionary  Accounts  by an  employee  or  partner  of Lord  Abbett are
subject to the post-trade reporting requirements of this Code.

VII.    Enforcement

The Secretary of the Funds and General  Counsel for Lord Abbett (who may be
the same person) each is charged with the responsibility of enforcing this Code,
and may appoint one or more employees to aid him in carrying out his enforcement
responsibilities.   The  Secretary   shall  implement  a  procedure  to  monitor
compliance with this Code through a periodic review of personal  trading records
provided  under  this  Code  against  transactions  in  the  Funds  and  managed
portfolios.  The  Secretary  shall bring to the  attention  of the Funds'  Audit
Committees any apparent  violations of this Code, and the Audit Committees shall
determine what action shall be taken as a result of such  violation.  The record
of any  violation of this Code and any action taken as a result  thereof,  which
may include  suspension or removal of the violator  from his position,  shall be
made a part of the permanent  records of the Audit  Committees of the Funds. The
Secretary  shall also prepare an annual  report to the  directors or trustees of
the Funds that (a)  summarizes  Lord  Abbett's  procedures  concerning  personal
investing,  including the procedures followed by partners in determining whether
to give approvals  under Section III and the procedures  followed by Ms. Herrera
in  determining  pursuant  to Section IV whether  any Funds have  determined  to
purchase or sell a security or are considering  such a purchase or sale, and any
changes  in those  procedures  during  the past  year,  and (b)  identifies  any
recommended  changes  in the  restrictions  imposed  by  this  Code  or in  such
procedures  with  respect  to the Code and any  changes  to the Code  based upon
experience  with the Code,  evolving  industry  practices or developments in the
regulatory environment.

The Audit  Committee  of each of the Funds and the General  Counsel of Lord
Abbett may determine in particular cases that a proposed transaction or proposed
series of transactions does not conflict with the policy of this Code and exempt
such  transaction or series of transactions  from one or more provisions of this
Code.
