The Fund

GOAL / PRINCIPAL STRATEGY

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


     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  forego  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 by investing in
     the Fund.


We or the Fund refers to Lord Abbett Affiliated Fund, Inc.

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

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

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

Bargain stocks are stocks of com-panies which we believe the market  undervalues
according to certain financial measurements of their intrinsic worth or business
prospects.

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

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 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.

(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           $650            $810             $983           $1,486
- -------------------------------------------------------------------------------
Class B shares           $646            $752             $982           $1,536

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

Class A shares           $650            $810             $983           $1,486

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.

                                Your Investment

PURCHASES


     The Fund offers in this  prospectus  four classes of shares:  Class 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 may be
     added to the NAV in the case of the Class A shares.  There is no front-end
     sales charge  in the  case  of  Class  B, C and P  shares,  although  there
     may be a contingent deferred sales charge ("CDSC") 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.


- --------------------------------------------------------------------------------
Share Classes

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 Fund.

          Withdrawal Plans (up to 12% per year)


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

     Class C shares, no front-end sales charge,  and no CDSC. Class P shares are

     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)



                                                               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 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 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.

     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  each
     quarter  and  distributes  net  capital  gains (if any) as  "capital  gains
     distributions" on an annual basis. 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 federal,  state and local tax
     rules that apply to you.



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.

     For more  information  about the services Lord Abbett provides to the Fund,
     see the Statement of Additional Information.

     Lord Abbett is entitled to a monthly fee based on the Fund's  average daily
     net assets for each month as follows:

          .50 of 1% on the first $200 million in assets
          .40 of 1% on the next $300 million
          .375 of 1% on the next $200 million
          .35 of 1% on the next $200 million
          .30 of 1% on the Fund's assets over $900 million

     For the fiscal  year ended  October 31,  1999,  the actual fee paid to Lord
     Abbett was at an effective annual rate of .31 of 1%. In addition,  the Fund
     pays all expenses not expressly assumed by Lord Abbett.

     Portfolio  Managers.  Lord Abbett  uses a team of  portfolio  managers  and
     analysts  acting  together  to manage  the Fund's  investments.  The senior
     members of the team are: Thomas Hudson Jr., Partner of Lord Abbett;  Robert
     Morris, Partner of Lord Abbett; and Eli Salzman, Portfolio Manager. Messrs.
     Hudson  and  Morris  have  been  with  Lord  Abbett  since  1982 and  1991,
     respectively.  Mr.  Salzman joined Lord Abbett in 1997 and previously was a
     Vice President with Mutual of America  Capital Corp.  since 1997 and a Vice
     President with Mitchell Hutchins Asset Management, Inc. from 1986 to 1997.

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.  The Fund may use these  transactions to change the risk
     and return  characteristics  of the Fund's  portfolio.  If we judge  market
     conditions  incorrectly or use a strategy that does not correlate well with
     the Fund's  investments,  it could result in a loss, even if we intended to
     lessen  risk or enhance  returns.  These  transactions  may involve a small
     investment  of cash compared to the magnitude of the risk assumed and could
     produce  disproportionate  gains or losses.  Also,  these  strategies could
     result in losses if the  counterparty to a transaction  does not perform as
     promised.

     Convertible  Securities.  The Fund may  invest  in  convertible  bonds  and
     convertible  preferred  stocks.  These investments tend to be more volatile
     than debt  securities  but tend to be less volatile and produce more income
     than their underlying common stocks.

     Debt  Securities.  The Fund may  invest in debt  securities  such as bonds,
     debentures,  government  obligations,  commercial  paper  and  pass-through
     instruments.  When interest  rates rise,  prices of these  investments  are
     likely to decline, and when interest rates fall, prices tend to rise. There
     is also the risk that an issuer of a debt security will fail to make timely
     payments of principal or interest to the Fund.

     Diversification. The Fund is a diversified fund, which generally means that
     with  respect to 75% of its total  assets,  it will not purchase a security
     if, as a result,  more than 5% of the Fund's total assets would be invested
     in  securities  of a single  issuer or the Fund would hold more than 10% of
     the outstanding voting securities of the issuer. U.S. government securities
     are not subject to these requirements.

     Foreign  Securities.  The Fund may  invest  up to 10% of its net  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 the 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.



     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.  The Fund will not
     invest more than 5% of its assets in high yield debt securities.

     Portfolio   Securities   Lending.   The  Fund  may   lend   securities   to
     broker-dealers  and financial  institutions  as a means of earning  income.
     This  practice  could  result in a loss or delay in  recovering  the Fund's
     securities,  if the borrower  defaults.  The Fund will limit its securities
     loans  to  30%  of  its  total   assets   and  all  loans   will  be  fully
     collateralized.

     Selling  Covered  Call  Options.  The Fund may write or sell  covered  call
     options on equity  securities  or stock indices that are traded on national
     securities exchanges. A call option gives the writer (seller) of the option
     the  obligation to sell the underlying  instrument.  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 will limit  covered  call  options on  securities
     having an aggregate market value not to exceed 10% of its total assets.

GLOSSARY OF SHADED TERMS

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

     In  selecting  dealers to  execute  portfolio  transactions  for 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 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 account and other criteria.

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

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

GUARANTEED SIGNATURE. An acceptable form of guarantee would be as follows:

o    In the case of the estate --

     Robert A. Doe
     Executor of the Estate of
     John W. Doe

     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,  on the
     prior page).


     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.

     Special  Retirement  Wrap  Program.  A program  sponsored by an  Authorized
     Institution showing one or more  characteristics  distinguishing it, in the
     opinion of Lord Abbett  Distributor,  from a Mutual Fund 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.

RECENT PERFORMANCE


     The  following is a discussion of recent  performance  for the twelve month
     period ending October 31, 1999.

     The past fiscal year was  characterized  by continued  overall  strength in
     both the broad equity market and the U.S. economy. Low interest rates and a
     deceleration  in earnings  have driven the U.S.  equity market for the last
     two and one-half  years.  This  environment  favored a very select group of
     large stocks that have had stable  earnings  growth.  Rather than venturing
     into  "unknown"  waters,  investors  stayed  the course  and  continued  to
     purchase  names  familiar to them,  remaining with companies that exhibited
     strong earnings stories.  The result,  however, is that many of the larger,
     more well-known growth names have become, in our opinion, quite expensive.

     In anticipation  of an improvement in the global economy,  we made an early
     entry into the energy  sector,  a strategy that paid off well for the Fund.
     In our view, the rise in oil prices  initiated by OPEC,  coupled with solid
     fundamentals  for many energy  companies,  helped to boost this sector.  In
     addition, the technology sector continued to outperform the general market.
     However, despite strong performance by a number of holdings in this sector,
     we recently began to reduce our exposure to technology,  as prices began to
     reach the upper  end of our  valuation  discipline.  We  reinvested  a good
     portion of the  proceeds

     from those  sales into more  traditional  cyclical  sectors  such as paper,
     chemicals and aluminum, and anticipate these areas will benefit from a rise
     in commodity prices as the global economy strengthens.

     In addition,  we have started to focus some  attention  toward the property
     and casualty insurance sector during this period, and will continue to seek
     out companies in this market segment that display  improving  fundamentals.
     At the same time, we are generally  underweighted  in financial  companies,
     which has worked to our advantage  since many of these stocks  continued to
     struggle during this period as interest rates  increased.  We believe there
     is only a small  chance that U.S.  interest  rates will  continue to climb.
     This view, coupled with the fact that many financial service companies have
     solid  fundamentals,  will likely  result in an increase in our exposure to
     the financial services area.

     As we look forward, we anticipate the global economy will continue to grow.
     However,  there  are  some  signs  that  the  robust  U.S.  economy  may be
     moderating.  A  slowdown  in  consumer  spending  is  possible  due to high
     consumer debt levels and a decrease in mortgage  refinancings (which reduce
     consumers' monthly mortgage payments).  In addition,  the recent volatility
     in the equity markets may serve to curtail spending previously attributable
     to the "wealth effect" from appreciated  portfolios.  Consequently,  we are
     moderately  underweighted  in consumer  stocks,  especially  those that are
     highly sensitive to changes in economic activity.

     deduction of the maximum initial sales charge of 5.75% applicable to Class
     A shares, with all dividends and distributions reinvested for the periods
     shown ending October 31, 1999 using the SEC-required uniform method to
     compute such return.

(1)  The service fees for Class A and P shares are paid quarterly. The first
     year's service fees on Class B and C shares are paid at the time of sale.

(2)  Reallowance/concession percentages and service fee percentages are
     calculated from different amounts, and therefore may not equal total
     compensation percentages if combined using simple addition. Additional
     Concessions may be paid to Authorized Institutions, such as your dealer,
     from time to time.

(3)  Concessions are paid at the time of sale on all Class A shares sold during
     any 12-month period starting from the day of the first net asset value
     sale. With respect to (a) Class A share purchases at $1 million or more,
     sales qualifying at such level under rights of accumulation and statement
     of intention privileges are included and (b) for Special Retirement Wrap
     Programs, only new sales are eligible and exchanges into the Fund are
     excluded. Certain purchases of Class A shares are subject to a CDSC.

(4)  Class B and C shares are subject to CDSCs.

(5)  With respect to Class B, C and P shares, 0.25%, 1.00% and 0.45%,
     respectively, of the average annual net asset value of such shares
     outstanding during the quarter (including distribution reinvestment shares
     after the first anniversary of their issuance) is paid to Authorized
     Institutions, such as your dealer. These fees are paid quarterly in
     arrears.

The Fund may not:

         (1) borrow  money,  except  that (i) the Fund may borrow from banks (as

         (including  the  amount  borrowed),  (ii) the Fund may  borrow up to an
         additional  5% of its total assets for  temporary  purposes,  (iii) the

         applicable law;

         (2) pledge  its  assets  (other  than to secure  borrowings,  or to the
         extent  permitted by the Fund's  investment  policies,  as permitted by
         applicable law);

         (3) engage in the  underwriting  of  securities,  except  pursuant to a
         merger or  acquisition  or to the extent that, in  connection  with the
         disposition  of its  portfolio  securities,  it may be  deemed to be an
         underwriter under federal securities laws;

         (4) make loans to other persons,  except that the acquisition of bonds,
         debentures  or  other  corporate  debt  securities  and  investment  in
         government  obligations,  commercial paper,  pass-through  instruments,
         certificates of deposit, bankers acceptances,  repurchase agreements or
         any similar  instruments  shall not be subject to this limitation,  and
         except  further  that  the Fund  may  lend  its  portfolio  securities,
         provided that the lending of portfolio  securities  may be made only in
         accordance with applicable law;

          (5) buy or sell  real  estate  (except  that the Fund  may  invest  in

         therein or issued by companies which invest in real estate or interests
         therein) or  commodities or commodity  contracts  (except to the extent
         the  Fund  may do so in  accordance  with  applicable  law and  without

         agencies or  instrumentalities  or (ii) 10% of the voting securities of
         such issuer;

         or

         (11)  pledge,   mortgage  or  hypothecate  its  assets,  however,  this
         provision  does not apply to the grant of escrow  receipts or the entry

         covered call options.

Although it has no current  intention to do so, the Fund may invest in financial
futures and options on financial futures.


For the year ended  October 31, 1999,  the  portfolio  turnover  rate was 62.30%
versus 56.49% for the prior year.


Lending  Portfolio  Securities.  The  Fund  may  lend  portfolio  securities  to
registered  broker-dealers.  These loans may not exceed 30% of the Fund's  total
assets.  The  Fund's  loans  of  securities  will be  collateralized  by cash or
marketable  securities  issued  or  guaranteed  by the  U.S.  Government  or its
agencies ("U.S.  Government Securities") or other permissible means. The cash or
instruments collateralizing the Fund's loans of securities will be maintained at
all times in an amount at least equal to the current  market value of the loaned
securities. From time to time, the Fund may allow to the borrower and/or a third
party that is not affiliated with the Fund and is acting as a "placing broker" a
part of the interest  received  with  respect to the  investment  of  collateral
received for securities loaned. No fee will be paid to affiliated persons of the
Fund.

By lending portfolio securities,  the Fund can increase its income by continuing
to receive interest on the loaned  securities as well as by either investing the
cash collateral in permissible investments,  such as U.S. Government Securities,


                                       3


<PAGE>

or obtaining  yield in the form of interest  paid by the borrower when such U.S.
Government  Securities  are used as  collateral.  The Fund will  comply with the
following conditions whenever it loans securities:  (i) the Fund must receive at
least 100%  collateral  from the  borrower;  (ii) the borrower must increase the
collateral  whenever the market value of the  securities  loaned rises above the
level of the  collateral;  (iii) the Fund must be able to terminate  the loan at
any time; (iv) the Fund must receive reasonable compensation with respect to the
loan, as well as any dividends,  interest or other  distributions  on the loaned
securities;  (v) the Fund may pay only  reasonable  fees in connection  with the
loan and (vi) voting  rights on the loaned  securities  may pass to the borrower
except that,  if a material  event  adversely  affecting  the  investment in the
loaned securities  occurs, the Fund's Board of Directors must terminate the loan
and regain the right to vote the securities.

Rule 144A  Securities.  We may  invest in  securities  qualifying  for resale to
"qualified  institutional buyers" under SEC Rule 144A that are determined by the
Board,  or by Lord  Abbett  pursuant  to the  Board's  delegation,  to be liquid
securities. The Board will review quarterly the liquidity of the investments the
Fund makes in such  securities.  Investments by the Fund in Rule 144A securities
initially determined to be liquid could have the effect of diminishing the level
of the Fund's  liquidity  during  periods of decreased  market  interest in such
securities among qualified institutional buyers.

Other Investment Policies (which can be changed without shareholder approval)
As stated in the Prospectus,  we may write covered call options which are traded
on a national securities exchange with respect to securities in our portfolio in
an attempt to  increase  our income and to provide  greater  flexibility  in the
disposition of our portfolio securities.  A "call option" is a contract sold for
a price (the "premium")  giving its holder the right to buy a specific number of
shares of stock at a specific  price prior to a specified  date. A "covered call
option" is a call option issued on securities already owned by the writer of the
call option for delivery to the holder upon the  exercise of the option.  During
the period of the option,  we forgo the  opportunity to profit from any increase
in the market price of the  underlying  security above the exercise price of the
option (to the extent that the increase  exceeds our net  premium).  We also may
enter into "closing purchase  transactions" in order to terminate our obligation
to deliver the  underlying  security  (this may result in a  short-term  gain or
loss).  A closing  purchase  transaction  is the purchase of a call option (at a
cost  which  may be more or less  than the  premium  received  for  writing  the
original call option) on the same  security,  with the same  exercise  price and
call period as the option previously  written.  If we are unable to enter into a
closing  purchase  transaction,  we may be required  to hold a security  that we
might otherwise have sold to protect against  depreciation.  We do not intend to
write covered call options with respect to securities  with an aggregate  market
value of more  than 10% of our gross  assets  at the time an option is  written.
This percentage limitation will not be increased without prior disclosure in our
current Prospectus.

Risk Factors. As stated in the Prospectus,  we may invest no more than 5% of our
net assets (at the time of  investment) in  lower-rated,  high-yield  bonds.  In
general,  the market for lower-rated,  high-yield bonds is more limited than the
market for higher-rated  bonds, and because trading in such bonds may be thinner
and less active,  the market  prices of such bonds may  fluctuate  more than the
prices  of  higher-rated  bonds,  particularly  in times of  market  stress.  In
addition, while the market for high-yield, corporate debt securities has been in
existence  for many years,  the market in recent  years  experienced  a dramatic
increase in the  large-scale  use of such  securities  to fund  highly-leveraged
corporate acquisitions and restructurings.  Accordingly, past experience may not
provide an accurate  indication of future  performance  of the  high-yield  bond
market,  especially during periods of economic recession.  Other risks which may
be  associated  with  lower-rated,   high-yield  bonds  include  their  relative
insensitivity to interest-rate  changes; the exercise of any of their redemption
or call provisions in a declining  market which may result in their  replacement
by lower-yielding bonds; and legislation, from time to time, which may adversely
affect  their  market.  Since the risk of default is higher  among  lower-rated,
high-yield   bonds,  Lord  Abbett's  research  and  analyses  are  an  important
ingredient in the selection of such bonds.  Through  portfolio  diversification,
good  credit  analysis  and  attention  to  current  developments  and trends in
interest rates and economic conditions, investment risk can be reduced, although
there is no  assurance  that losses  will not occur.  The Fund does not have any
minimum rating criteria  applicable to the  fixed-income  securities in which it
invests.

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  is  being  deferred  under a
     plan ("equity  based  plan") that deems the  deferred  amounts to be
     invested in shares of the Fund for later distribution to the directors/
     trustees. The amounts of the aggregate compensation payable by the
     Fund as of October  31,  1999 deemed  invested  in Fund  shares,  including
     dividends  reinvested  and  changes in net asset value  applicable  to such
     deemed investments,  were: Mr. Bigelow, $177,464 ; Mr. Dixon, $337,337 ;
     Mr. Jansing, $575,176; Mr.  MacDonald,  $422,105 ; Mr. Millican,  $743,736
     and Mr. Neff, $657,888 . If the amounts deemed
     invested in Fund shares were added to each  director's  actual  holdings of
     Fund shares as of October 31,  1999,  each would own,  the  following:  Mr.
     Bigelow,  $177,464;  Mr. Dixon, $351,857;  Mr. Jansing, $923,465;
     Mr. McDonald,$780,769; Mr. Millican, $743,736; and Mr. Neff, $721,255.


2.   The amounts in Column 3 were accrued by the Lord Abbett-Sponsored funds for
     the twelve  months ended  October 31, 1999.

3.   This column shows aggregate compensation, including 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/trustees had the option to convert
     their accrued benefits under the retirement plan.  All of the 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.

Except where indicated,  the following  executive officers of the Fund have been
associated  with Lord  Abbett  for over five  years.  Messrs.  Carper,  Hilstad,
Hudson,  Morris and Walsh are partners of Lord Abbett; the others are employees.
None have received compensation from the Funds.

As of February 15, 2000, our officers and directors, as a group, owned less than
1% of our  outstanding  shares and there were no record holders of 5% or more of
the Fund's outstanding shares, other than Lord Abbett Distributor.

                                       3.
                     Investment Advisory and Other Services

The services  performed by Lord Abbett are  described  in the  Prospectus  under
"Management." Under the Management Agreement,  we pay Lord Abbett a monthly fee,
based on average daily net assets for each month, at the annual rate of .5 of 1%
of the portion of our net assets not in excess of $200,000,000;  .4 of 1% of the
portion in excess of $200,000,000, but not in excess of $500,000,000; .375 of 1%
of the portion in excess of $500,000,000, but not in excess of $700,000,000; .35
of 1%  of  the  portion  in  excess  of  $700,000,000,  but  not  in  excess  of
$900,000,000; and .3 of 1% of the portion in excess of $900,000,000. This fee is
allocated among Class A, B and C based on the classes'  proportionate  shares of
such average daily net assets.

For the fiscal years ended October 31, 1999,  1998 and 1997, the management fees
paid to Lord  Abbett  by the  Fund  amounted  to  $26,317,934,  $22,192,209  and
$17,683,694 respectively.


The Fund pays all  expenses  not  expressly  assumed by Lord  Abbett,  including
without  limitation  12b-1  expenses,  outside  directors'  fees  and  expenses,
association  membership  dues,  legal and  auditing  fees,  taxes,  transfer and
dividend disbursing agent fees,  shareholder  servicing costs, expenses relating
to  shareholder  meetings,  expenses of  preparing,  printing and mailing  stock
certificates and shareholder  reports,  expenses of registering our shares under
federal and state securities laws,  expenses of preparing,  printing and mailing
prospectuses to existing shareholders,  insurance premiums,  brokerage and other
expenses connected with executing portfolio transactions.

Lord Abbett Distributor LLC serves as the principal underwriter for the Fund.

Deloitte & Touche LLP, Two World Financial Center,  New York, New York 10281 are
the  independent  auditors of the Fund and must be approved at least annually by
our Board of Directors to continue in such capacity. They perform audit services
for the Fund,  including the examination of financial statements included in the
Fund's Annual Report to Shareholders.

The Bank of New York ("BNY"),  48 Wall Street, New York, New York, 10286, is the
Fund's custodian.  In accordance with the requirements of Rule 17f-5, the Fund's
Board of Directors  have approved  arrangements  permitting  the Fund's  foreign
assets not held by BNY or its foreign  branches to be held by certain  qualified
foreign banks and depositories.


United Missouri Bank of Kansas City, N.A. Tenth and Grand Kansas City, Missouri,
64141, acts as the transfer agent and dividend disbursing agent for each Fund.


                                       4.
                             Portfolio Transactions


The Fund'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  (if any) and dealer markups and markdowns and
brokerage  commissions and taking into account the full range and quality of the
brokers' services.  Consistent with obtaining best execution,  we generally pay,
as described  below, a higher  commission  than some brokers might charge on the
same  transaction.  This  policy  with  respect to best  execution  governs  the
selection  of  brokers or dealers  and the  market in which the  transaction  is
executed.  To the extent  permitted by law, we may, if considered  advantageous,
make a purchase from or sale to another Lord  Abbett-sponsored  fund without the
intervention of any broker-dealer.

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

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

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

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


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

If other  clients of Lord Abbett buy or sell the same  security at the same time
as  a  Lord  Abbett-sponsored  fund  does,  transactions  will,  to  the  extent
practicable,  be allocated among all participating accounts in proportion to the
amount  of each  order  and will be  executed  daily  until  filled so that each
account shares the average price and commission  cost of each day. Other clients
who direct that their brokerage business be placed with 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  October  31,1999,  1998,  and 1997 , we paid total
commissions to independent dealers of $11,088,462, $12,832,030 and $7,681,037,
respectively.

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

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

The  maximum  offering  price of our  Class A shares  on  October  31,  1999 was
computed as follows:

 Net asset value per share (net assets divided by
    shares outstanding)...................................................$16.22

Maximum offering price per share (net asset value
    divided by .9425) ....................................................$17.21


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

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

Lord Abbett  Distributor  is obligated to distribute our shares on a best effort
basis.  Our shares are offered on a continuous  basis. For the last three fiscal
years,  Lord Abbett  Distributor,  as our  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 Fund offers investors five 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.



                                       10


<PAGE>


Class A Shares.  If you buy Class A shares,  you pay an initial  sales charge on
investments  of less than $1 million (or on investments  for  employer-sponsored
retirement  plans under the Internal  Revenue Code  (hereinafter  referred to as
"Retirement Plans") with less than 100 eligible employees or on investments that
do not  qualify to be under a "special  retirement  wrap  program"  as a program
sponsored  by an  authorized  institution  showing  one or more  characteristics
distinguishing  it, in the opinion of Lord Abbett Distributor from a mutual fund
wrap fee program). If you purchase Class A shares as part of an investment of at
least $1 million (or for Retirement  Plans with at least 100 eligible  employees
or under a  special  retirement  wrap  program)  in  shares  of one or more Lord
Abbett-sponsored  funds,  you will not pay an initial sales  charge,  but if you
redeem  any of those  shares  within 24 months  after the month in which you buy
them, you may pay to the Fund a contingent  deferred sales charge ("CDSC") of 1%
except for redemptions under a special  retirement wrap program.  Class A shares
are subject to service and  distribution  fees that are  currently  estimated to
total annually approximately 33 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 below.


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

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

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

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

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


                                       11


<PAGE>

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

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

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

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

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

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. As described in the  Prospectus,  the Fund
has adopted a Distribution Plan and Agreement  pursuant to Rule 12b-1 of the Act
for each of the three Fund Classes: the "A Plan", the "B Plan" and the "C 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'  shareholders.  The expected
benefits  include  greater sales and lower  redemptions  of Class shares,  which
should allow each Class to maintain a consistent cash flow, and a higher quality
of service to  shareholders by authorized  institutions  than would otherwise be
the case.  During the last fiscal  year,  the Fund  accrued or paid through Lord
Abbett to authorized institutions $27,926,819 under the A Plan, $4,281,069 under
the B Plan, $1,584,742  under the C Plan and $9,131 under Class P Plan.  Lord
Abbett uses all amounts received under each Plan as described in the Prospectus
and for payments to dealers for (i) providing  continuous  services to the
shareholders,  such as answering shareholder inquiries, maintaining records, and
assisting shareholders in making redemptions,  transfers,  additional  purchases
and exchanges and (ii) their assistance in distributing shares of the Fund.

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

Contingent  Deferred Sales Charges. A Contingent  Deferred Sales Charge ("CDSC")
(i) applies  regardless of class, (ii) will not apply to shares purchased by the
reinvestment of dividends or capital gains distributions; (iii) 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 (iv) 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 series  acquired  through  exchange of such shares) on
which the 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 series 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 to the Fund in connection with the sale of Class B
shares.

To determine  whether the CDSC applies to a redemption,  the 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 contingent  deferred sales charge will depend on the number of
years since you invested and the dollar amount being redeemed,  according to the
following schedule:

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


                                       13


<PAGE>

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

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

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

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

Shareholders in other Lord  Abbett-sponsored  funds and AMMF have the same right
to  exchange  their  shares for the  corresponding  class of the Fund's  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.

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

Rights of Accumulation.  As stated in the Prospectus,  purchasers (as defined in
the Prospectus) may accumulate their investment in Lord  Abbett-sponsored  funds
(other than LAEF, LARF,  LASF,  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 director'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 and employees and other family  members
thereof.


                                       15


<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 wrap fee program"), (e)
by employees,  partners and owners of  unaffiliated  consultants and advisors to
Lord Abbett, Lord Abbett Distributor or Lord Abbett-sponsored  funds who consent
to such  purchase if such persons  provide  service to Lord Abbett,  Lord Abbett
Distributor  or such  funds on a  continuing  basis and are  familiar  with such
funds, (f) through Retirement Plans with at least 100 eligible employees, (g) in
connection with a merger, acquisition or other reorganization, and (h) through a
"special retirement wrap program" sponsored by an authorized institution showing
one or more  characteristics  distinguishing  it, in the  opinion of Lord Abbett
Distributor from a mutual fund wrap 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 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 Fund has
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  supplementary  by
Lord Abbett Distributor or the Fund to carry out the order. The signature(s) and
any legal capacity of the signer(s) must be guaranteed by an eligible guarantor.
See the Prospectus for expedited redemption procedures.

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

Our Board of  Directors  may  authorize  redemption  of all of the shares in any
account  in which  there are  fewer  than 25  shares.  Before  authorizing  such
redemption, the Board must determine that it is in our economic best interest or
necessary  to  reduce   disproportionately   burdensome  expenses  in  servicing
shareholder  accounts.  At least 6 months  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 Fund and/or any
other  Eligible Fund is described in the  Prospectus.  To avail yourself of this
method you must complete the application form,  selecting the time and amount of
your bank checking account  withdrawals and the funds for investment,  include a
voided, unsigned check and complete the bank authorization.


                                       16


<PAGE>

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, on redemptions over 12% per year, the CDSC will apply to
the entire  redemption.  Therefore,  please  contact the Fund 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,  including 401(k)plans excluding 401(k) plans. The forms name
Investors Fiduciary Trust Company as custodian and contain
specific   information   about  the  plans.   Explanations  of  the  eligibility
requirements,  annual  custodial fees and allowable tax advantages and penalties
are set forth in the  relevant  plan  documents.  Adoption of any of these plans
should be on the advice of your legal counsel or qualified tax adviser.

                                       6.
                                   Performance


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

In  calculating  total  returns for Class A shares,  the current  maximum  sales
charge of 5.75% (as a  percentage  of the offering  price) is deducted  from the
initial  investment (unless the return is shown at net asset value). For Class B
shares,  the payment of the applicable CDSC (5.0% prior to the first anniversary
of purchase, 4.0% prior to the second anniversary of purchase, 3.0% prior to the
third and fourth anniversaries of purchase,  2.0% prior to the fifth anniversary
of purchase,  1.0% prior to the sixth anniversary of purchase and no CDSC on and
after the sixth  anniversary  of purchase)  is applied to the Fund's  investment
result for that class for the time  period  shown  (unless  the total  return is
shown at net asset value).  For Class C shares,  the 1.0% CDSC is applied to the
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  method  described  above,  the  Fund's  average  annual
compounded  rates of total  return for the last one,  five and ten  fiscal-years
ending  on  October  31,  1999  are  as  follows:   3.90%,  15.65%  and  14.15%,
respectively,  for the  Fund's  Class A shares.  For the fiscal  year  ending on
October 31, 1999 and for the period since inception, August 1, 1996, the average
annual compounded rate of total return was 5.03 % and 18.27%, respectively,  for
the Fund's Class B shares.  For the fiscal year ending  October 31, 1999 and for
the period since inception,  August 1, 1996, the average annual  compounded rate
of total  return  was 9.41% and  9.88%,  respectively,  for the  Fund's  Class C
shares.

Yield  quotation for each Class is based on a 30-day period ended on a specified
date, computed by dividing the net investment income per share earned during the
period by the maximum  offering price per share of such class on the last day of
the period.  This is  determined  by finding the  following  quotient:  take the
dividends  and interest  earned during the period for a class minus its expenses
accrued for the period and divide by the product of (i) the average daily number
of Class  shares  outstanding  during the period  that were  entitled to receive
dividends  and (ii) the  maximum  offering  price per share of such class on the
last day of the period.  To this  quotient add one.  This sum is  multiplied  by
itself  five  times.   Then  one  is   subtracted   from  the  product  of  this
multiplication  and the remainder is  multiplied  by two.  Yield for the Class A
shares reflects the deduction of the maximum initial sales charge,  but may also
be shown based on the Class A net asset value per share.  Yields for Class B and
C shares do not reflect the  deduction of the CDSC.  For the 30-day period ended
October 31, 1999 the yield for the Class A shares of Fund was 0.94%.

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


                                       7.
                                      Taxes
The 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,  the  Fund  (but  not its  shareholders)  will be
relieved of federal income taxes on the amount it  distributes to  shareholders.
If in any  taxable  year the Fund does not  qualify  as a  regulated  investment
company,  all of its  taxable  income  will be  taxed  to the  Fund  at  regular
corporate rates.

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

Upon sale,  exchange or  redemption  of shares of the 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 months 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.

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 is not  otherwise  subject to
backup withholding.

The writing of call options and other investment  techniques and practices which
the Fund may utilize may affect the character and timing of the  recognition  of
gains and  losses.  Such  transactions  may  increase  the amount of  short-term
capital  gain  realized  by the Fund,  which is taxed as  ordinary  income  when
distributed to shareholders.

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

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


                                       18


<PAGE>

Dividends paid by the 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 the Fund for
more than 45 days to qualify for the deduction on dividends paid by the Fund.

Gain and loss realized by the 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 the Fund  purchases  shares in certain  foreign  investment  entities  called
"passive foreign investment  companies," the Fund may be subject to U.S. 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 either  the Fund or its  shareholders  in respect of
deferred  taxes arising from such  distributions  or gains.  If the 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,  the
Fund might be required to include in income each year a portion of the  ordinary
earnings and net capital  gains of the  qualified  electing  fund,  even if such
amount were not distributed to the Fund.

The  foregoing  discussion  relates  solely to U.S.  federal  income  tax law as
applicable  to U.S.  persons  (U.S.  citizens  or  residents  and United  States
domestic corporations,  partnerships,  trusts and estates). Each shareholder who
is not a U.S.  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 Fund



Lord Abbett  Affiliated Fund, Inc. was organized in 1934 and was  reincorporated
under  Maryland law on November 26, 1975. The Fund has  2,000,000,000  shares of
authorized  capital stock  consisting of five classes (A, B, C, P and Y), $0.001
par value. The Fund is an open-end,  diversified  management investment company.
The Board of Directors  will allocate these  authorized  shares of capital stock
among the classes from time to time. All shares have equal noncumulative  voting
rights and equal  rights  with  respect to  dividends,  assets and  liquidation,
except  for   certain   class-specific   expenses.   They  are  fully  paid  and
nonassessable when issued and have no preemptive or conversion rights.

The Fund's By-Laws provide that the Fund shall not hold an annual meeting of its
stockholders  in any year unless one or more matters are required to be acted on
by  stockholders  under the Act, or unless  called by a majority of the Board of
Directors  or by  stockholders  holding at least one quarter of the stock of the
Fund  outstanding  and  entitled  to vote at the  meeting.  When any such annual
meeting is held, the stockholders  will elect directors and vote on the approval
of the independent auditors of the Fund.

Rule 18f-2  under The  Investment  Company Act of 1940,  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.



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

                                                                 Affiliated Fund

GOAL / PRINCIPAL STRATEGY

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


     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  forego  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 Lord Abbett Affiliated Fund, Inc.

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

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

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


Bargain stocks are stocks of com-panies which we believe the market  undervalues
according to certain financial measurements of their intrinsic worth or business
prospects.

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


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 Fund and
their risks.

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 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 would be:

Share Class            1 Year           3 Years         5 Years         10 Years
Class Y shares           $44             $138           $241              $542
- --------------------------------------------------------------------------------



Management fees are payable to Lord, Abbett & Co. ("Lord Abbett") for the Fund's
investment management.

Other  expenses  include fees paid for  miscellaneous  items such as shareholder
service fees and professional fees.


4 The Funds


<PAGE>

                                                       Growth Opportunities Fund

GOAL / PRINCIPAL STRATEGY

     The Fund's investment objective is capital appreciation.


     To pursue  this goal,  we normally  invest  primarily  in common  stocks of
     mid-sized  companies with outstanding equity securities having an aggregate
     market  value  between $1 billion  and $6  billion.  The Fund uses a growth
     style of  investing  which  means  that we favor  companies  that  show the
     potential  for  stronger  than  expected  earnings or growth.  Under normal
     circumstances, at least 65% of our total assets will consist of investments
     made in growth companies,  as determined at the time of purchase.  The Fund
     may invest up to 35% of its assets in foreign securities.

     Typically, in choosing stocks, we look for companies using

     o    quantitative  research to identify  mid-sized  companies with superior
          growth possibilities.

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


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


     While typically fully invested,  at times we may take a temporary defensive
     position by investing  some of our assets in  short-term  debt  securities.
     This could  reduce the  benefit  from any upswing in the market 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 growth
     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.  Growth  stocks may grow
     faster than other  stocks and may be more  volatile.  In  addition,  if the
     Fund's  assessment of a company's  potential for growth is wrong, the price
     of the  company's  stock  may  decrease  below  the price at which the Fund
     purchased the stock.

     Foreign  securities,  in which the Fund may  invest may  present  risks not
     typically  associated  with domestic  securities.  Foreign  markets and the
     securities  traded in them are not subject to the same degree of regulation
     as U.S.  markets  which may increase  the degree of market risk  associated
     with them.  Foreign  securities may also be subject to liquidity,  currency
     and  political  risk.  Foreign  investments  may be  affected by changes in
     currency  rates or  currency  controls.  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.

     Investors  should  also be aware that the Fund has the ability to invest in
     derivatives, the value of which may fluctuate greatly.

     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.

GOAL / PRINCIPAL STRATEGY

     The Fund's  investment  objective  is to seek high  current  income and the
     opportunity  for  capital  appreciation  to  produce a high  total  return.
     Normally, we invest in lower-rated debt securities,  sometimes called "junk
     bonds," which entail greater risks than  investments in  higher-rated  debt
     securities.


     We  believe  that  a  high  total  return   (current   income  and  capital
     appreciation)  may  be  derived  from  an  actively  managed,   diversified
     portfolio of investments.  Under normal  circumstances,  we invest at least
     65% of our total assets in lower-rated debt  securities,  some of which are
     convertible into common stock or have warrants to purchase common stock.


     We seek unusual values, particularly in lower-rated debt securities. Higher
     yield on debt  securities  can occur during  periods of inflation  when the
     demand for borrowed money is high. Also, buying  lower-rated bonds when the
     credit  risk is above  average  but,  we  think,  likely to  decrease,  may
     generate higher yields.


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


MAIN RISKS

     The  lower-rated  bonds in which the Fund  invests  involve  risks that the
     bond's  issuers will not make payments of interest and  principal  payments
     when due. Some issuers may default as to principal and/or interest payments
     after we purchase  their  securities.  Through  portfolio  diversification,
     credit  analysis  and  attention  to  current  developments  and  trends in
     interest  rates and economic  conditions,  we attempt to reduce  investment
     risk, but losses may occur. In addition,  the value of your investment will
     change as interest rates  fluctuate.  When interest  rates  decline,  share
     value may rise. When interest rates rise, share value may decline. The Fund
     also uses  investment  practices that could adversely  affect  performance,
     such as investments in foreign securities and illiquid securities.


     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.

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

High yield debt  securities,  commonly  known as "junk  bonds,"  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.

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.  Performance for Class Y shares is not shown because
     the class has less than one year of performance. Returns for Class Y shares
     are expected to be somewhat higher than those of Class A shares of the Fund
     because Class Y shares have lower expenses.

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 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 would be:

Share Class            1 Year       3 Years       5 Years          10 Years
Class Y shares           $88         $274           $477           $1,061
- --------------------------------------------------------------------------------



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

Other  expenses  include fees paid for  miscellaneous  items such as shareholder
service fees and professional fees.

Lord Abbett is currently waiving the managemnt fees and subsidizing the other
expenses of the Fund.  Lord Abbett may stop waiving the management fees and
subsidizing the other expenses at any time.  The total operating expense ratio
with the fee waiver and expense subsidy for Class Y shares is 0.0% of average
net assets.

GOAL / PRINCIPAL STRATEGY


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

     To pursue this goal,  the Fund invests in stocks of  companies  principally
     based outside the United States.  Under normal conditions,  at least 80% of
     the Fund's assets will be invested in stocks of companies in at least three
     different countries outside the United States.

     The Fund intends to primarily  invest in stocks of small  companies,  those
     with market capitalizations of less than $2 billion,  although the Fund may
     also invest in stocks of larger companies.

     We look for:

     o    developing global trends on an industry-by-industry basis

     o    companies  which are the  strongest  or the best  positioned  in those
          industries

     o    companies selling at attractive prices

     o    companies we see as having the best potential for growth or profits

     We may limit the number of  holdings  in the Fund to a greater  degree than
     other similar funds in an effort to prevent the dilution of the performance
     of securities  held in the  portfolio.  However,  the Fund is a diversified
     fund.

     The Fund may temporarily  reduce its stock holdings for defensive  purposes
     in response to adverse market conditions and invest in domestic, Eurodollar
     and foreign  short-term money market  instruments.  This could  potentially
     reduce  the Fund's  ability  to  benefit  from an 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,  such as market risk. The value of your investment in the
     Fund will fluctuate in response to movements in the  securities  markets in
     general and to the changing prospects of individual  companies in which the
     Fund invests. In addition, the Fund is subject to the risks of investing in
     foreign securities and in the securities of small companies.

     Investing  in  small  companies   generally  involves  greater  risks  than
     investing in the stocks of large  companies.  Small companies may have less
     experienced management,  limited product lines, unproven track records, and
     limited financial  resources.  Their securities may carry increased market,
     liquidity, and other risks.

     Foreign securities may present risks not typically associated with domestic
     securities.  Foreign  markets  and the  securities  traded  in them are not
     subject to the same degree of regulation as U.S. markets which may increase
     the degree of market risk associated with them. Foreign securities may also
     be subject to liquidity,  currency and political risk. Foreign  investments
     may be  affected by changes in currency  rates or currency  controls.  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.

     Investing in both small and international companies generally involves some
     degree of  information  risk.  That  means  that key  information  about an
     issuer, security or market may be inaccurate or unavailable.

     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 by investing in
     the Fund.

                                                                Large-Cap Series




GOAL / PRINCIPAL STRATEGY

     The Fund's  investment  objective is growth of capital and growth of income
     consistent with reasonable risk.

     To pursue this goal, the Fund purchases stocks of large, seasoned, U.S. and
     multinational companies which we believe are undervalued. Under normal
     circumstance at least 65% of the Fund's total assets will consist of
     investments mad in large-cap companies, determined at the time of purchase.
     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  forego  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.

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

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

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

Bargain stocks are stocks of com-panies which we believe the market  undervalues
according to certain financial measurements of their intrinsic worth or business
prospects.


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

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.

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 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 would be:


Share Class         1 Year         3 Years        5 Years        10 Years
Class Y shares      $113           $353           $612           $1,352

                                                          Small-Cap Value Series



GOAL / PRINCIPAL STRATEGY

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

     To pursue this goal,  the Fund invests  primarily in equity  securities  of
     small  companies  with  market  capitalizations  of less  than $1  billion.
     Typically, in choosing stocks, we look for companies using

     o    quantitative  research to evaluate  various  criteria,  including  the
          price of  shares  in  relation  to book  value,  sales,  asset  value,
          earnings, dividends and cash flow.

     o    fundamental research to assess the dynamics of each company within its
          industry and within the economy.  We evaluate the  company's  business
          strategies  by  assessing   management's   ability  to  execute  those
          strategies, and by evaluating the adequacy of its financial resources.

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

     While typically fully invested, we may take a temporary  defensive position
     by investing some of our assets in  short-term  debt  securities.  This
     could  reduce the benefit  from any upswing in the market 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,  such as market risk.The value of your investment in the
     Fund will fluctuate in response to movements in the  securities  markets in
     general and to the changing prospects of individual  companies in which the
     Fund invests. In addition, the Fund is subject to the risks of investing in
     foreign securities and in the securities of small companies.

     Investing  in  small  companies   generally  involves  greater  risks  than
     investing in the stocks of large  companies.  Small companies may have less
     experienced management,  limited product lines, unproven track records, and
     limited financial  resources.  Their securities may carry increased market,
     liquidity, and other risks.

     Foreign securities may present risks not typically associated with domestic
     securities.  Foreign  markets  and the  securities  traded  in them are not
     subject to the same degree of regulation as U.S. markets which may increase
     the degree of market risk associated with them. Foreign securities may also
     be subject to liquidity,  currency and political risk. Foreign  investments
     may be  affected by changes in currency  rates or currency  controls.  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.

     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 Small- Cap Value Series of Lord Abbett  Research  Fund,
Inc.

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

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

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



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

     800-821-5129.

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

     Fund may suspend redemptions, or postpone payment for more than seven days,
     as permitted by federal securities laws.

     By Wire. In order to receive funds by wire,  our servicing  agent must have

DISTRIBUTIONS AND TAXES


     The Funds  normally  pay  dividends  from  their net  investment  income as
     follows:  quarterly,  for the Affiliated Fund; monthly,  for the High Yield
     Fund;  semi-annually,  for the Large-Cap Series;  and annually,  for Growth
     Opportunities Fund,  International  Series and Small-Cap Value Series. Each
     Fund   distributes   net  capital   gains  (if  any)  as   "capital   gains
     distributions" on an annual basis. Your distributions will be reinvested in
     your Fund unless you instruct the Fund to pay them to you in cash.  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 Funds,  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.




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
     losses if the counterparty to a transaction does not perform as promised.



     Closed-End  Investment  Companies.  Each of the Growth  Opportunities Fund,
     International  Series,  Large-Cap  Series and  Small-Cap  Value  Series may
     invest  in  shares  of  closed-end  investment  companies  if bought in the
     primary or secondary  market with a fee or  commission  no greater than the
     customary  broker's  commission.  Each of the Growth Opportunities Fund,
     Large-Cap  Value  Series and Small-Cap  Series may not invest more than 5%
     of its assets in  closed-end investment companies.

     Diversification.  Each Fund is a  diversified  fund,  which means that with
     respect to 75% of its total assets,  it will not purchase a security if, as
     a result,  more than 5% of the Fund's  total  assets  would be  invested in
     securities  of a single  issuer or the fund would hold more than 10% of the
     outstanding  voting  securities of the issuer.  This does not apply to U.S.
     government securities.

     Depository  Receipts.  The  International  Series and the Small-Cap Value
     Series may invest in  Depository Receipts which are securities,  typically
     issued by a financial institution (a "depository"), that evidence ownership
     interests in a security or a pool of  securities  issued by a foreign
     issuer (the  "underlying  issuer") and deposited with the depository.
     Generally, Depository Receipts in registered form  are  designed  for  use
     in U.S.  securities  markets  and  Depository Receipts in bearer form are
     designed for use in securities  markets outside the  United  States.These
     Funds' may  invest  in  sponsored  and  unsponsored Depository Receipts.
     For purposes of the International  Series' investment policies,
     investments  in  Depository  Receipts  will  be  deemed  to  be
     investments in the underlying securities.


     Equity  Securities.  Each  Fund  other  than the High  Yield  Fund  invests
     primarily in equity securities. The High Yield Fund may invest up to 20% of
     its  total  assets in  equity  securities.  These  include  common  stocks,
     preferred   stocks,   convertible   securities,   warrants,   and   similar
     instruments.  Common stocks, the most familiar type, represent an ownership
     interest in a corporation.  Although  equity  securities  have a history of
     long-term growth in their value, their prices fluctuate based on changes in
     a company's financial condition and on market and economic conditions.

     Emerging  Countries Risk. The  International  Series may invest in emerging
     country  securities.  The securities markets of emerging countries are less
     liquid,  are especially  subject to greater price volatility,  have smaller
     market capitalizations, have less government



24 For More Information


<PAGE>


     regulation  and are not subject to as extensive  and  frequent  accounting,
     financial and other  reporting  requirements  as the securities  markets of
     more developed countries.  Further,  investing in the securities of issuers
     located in certain emerging  countries may involve a risk of loss resulting
     from problems in security  registration and custody or substantial economic
     or  political  disruptions.  These risks are not normally  associated  with
     investments in more developed countries.

     Futures  Contracts and Options on Futures  Contracts.The High Yield  Fund,
     Growth  Opportunities  Fund, International  Series and  Large-Cap  Series
     may engage in financial futures transactions. 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. The High Yield Fund may not invest more than
     5% of its  assets in such  transactions.  The  Growth  Opportunities  Fund,
     International  Series and Large-Cap  Series will not enter into such
     transactions,  if  the  aggregate  market  value  of the
     securities  covered by such contracts exceeds 50% of each such Fund's total
     assets.

     The Small-Cap Value Series may not purchase or sell stock index futures if,
     immediately after a purchase or sale, more than one-third of its net assets
     would be hedged. In addition, except in the case of a call written and held
     on the same index,  the  Small-Cap  Value Series 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  options  or  futures   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.

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

     Foreign Currency Transactions The Growth Opportunities Fund,  International
     Series  and the  Small-Cap  Value  Series  may  purchase  or  sell  foreign
     currencies on a cash basis or through forward contracts. A forward contract
     involves an obligation to purchase or sell a specific  currency at a future
     date at a price set at the time of the contract. Although these Funds do
     not  normally  engage in  extensive
     currency  hedging,  they may use foreign  currency  transactions to seek to
     protect against  anticipated  changes in future foreign  currency  exchange
     rates.  It may be difficult or  impractical  to hedge currency risk in many
     emerging countries.

     In addition,  the  International  Series may enter into such  transactions
     to seek to increase  total return,  which is considered a speculative
     practice.  The Fund  generally would not enter
     into a forward  contract  with a term  greater  than one year.  Under  some
     circumstances,  the Fund may commit a substantial portion or the entire
     value of its portfolio to the completion of forward contracts.

     The use of foreign  currency  transactions  is subject to the general  risk
     that the portfolio managers will not accurately predict currency movements,
     and the Funds'  returns  could be reduced.  In  addition,  forward  foreign
     currency  exchange  contracts  and  other  privately   negotiated  currency
     instruments  offer less protection  against  defaults than is available for
     currency  instruments traded on an exchange.  Since these contracts are not
     guaranteed by an exchange or  clearinghouse,  a default on a contract would
     deprive a Fund of unrealized profits, transaction costs, or the benefits of
     a currency  hedge,  or could  force the Fund to cover its  purchase or sale
     commitments,  if any, at the current market price.  Currency exchange rates
     may fluctuate  significantly over short periods of time, causing the NAV of
     the  Fund involved  to  fluctuate.
     Currency  exchange rates may be affected  unpredictably by the intervention
     of U.S.  or  foreign  governments  or



                                                         For More Information 25


<PAGE>

     central  banks,  or the failure to  intervene,  or by currency  controls or
     political developments in the United States or abroad.


     Foreign Securities. The Affiliated Fund and High Yield Fund will limit
     their investments in foreign securities to 10% and 20%, respectively, of
     their total assets. The International  Series may invest all of its assets
     in foreign  securities;  the Growth  Opportunities Fund and Small-Cap Value
     Series will limit their  investments in foreign  securities to 35% of their
     respective total assets. The  Large-Cap  Series may invest up to 10% 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.  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.


     Investment  Funds. The  International  Series may invest (normally not more
     than 5% of the Fund's total  assets) in  investment  funds.  Some  emerging
     countries have laws and regulations that currently  preclude direct foreign
     investment in the securities of their companies.  However, indirect foreign
     investment  in the  securities  of  such  countries  is  permitted  through
     investment  funds  which  have been  specifically  authorized.  If the Fund
     invests in such investment  funds,  the Fund's  shareholders  will bear not
     only  their  proportionate  share of the  expenses  of the Fund  (including
     operating  expenses and the fees of Lord Abbett),  but also will indirectly
     bear similar expenses of the underlying investment funds.

     Investment Grade Debt Securities. These are debt securities which are rated
     in one of the four highest grades  assigned by Moody's  Investors  Service,
     Inc., Standard & Poor's Ratings Services or Fitch Investors Service, or are
     unrated but determined by Lord Abbett to be equivalent in quality.

     Options  Transactions.  The Growth  Opportunities Fund, High Yield Fund,
     International Series and Small-Cap  Value  Series  may  purchase  and write
     put and call  options on equity  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.  Each of the three Funds  listed above may write
     only covered put options to the extent that cover for such options does not
     exceed 25% of the Fund's net assets.  Each will not  purchase an option if,
     as a result  of such  purchase,  more  than 20% (in the case of the  Growth
     Opportunities  Fund and Small-Cap  Value Series) and 5% (in the case of the
     International  Series) of its net assets  would be invested in premiums for
     such options.




26 For More Information


<PAGE>




     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.

     All Funds may write  (sell)  only  "covered"  options.  This means that
     Fund may only sell call options on securities  which the Fund owns. 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.The  Affiliated  Fund, Growth
     Opportunities Fund, International
     Series and  Large-Cap  Series  will only write  "covered"  call  options on
     securities  having an  aggregate  market  value  not to  exceed  10% of the
     Affiliated Fund's assets or 5% of the Growth Opportunities Fund,
     International  Series' and Large-Cap Series' assets.

     The High Yield Fund will only write  covered  call  options and secured put
     options on securities having an aggregate market value not to exceed 25% of
     the High Yield Fund's assets.

     Risks of Futures  Contracts  and Options  Transactions.  A Fund's
     transactions,  if any,  in  futures,  options on futures  and other
     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 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 International 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.


     Portfolio   Securities   Lending.   Each  Fund  may  lend   securities   to
     broker-dealers  and financial  institutions,  as a means of earning income.
     This  practice  could  result  in a loss or  delay in  recovering  a Fund's
     securities,  if the borrower defaults. The Affiliated Fund, High Yield Fund
     and International  Series will limit their securities loans to 30% of their
     total assets,  while the Growth  Opportunities  Fund,  Large-Cap Series and
     Small-Cap  Value  Series will limit their  securities  loans to 5% of their
     total assets.

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

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



GUARANTEED SIGNATURE. An acceptable form of guarantee would be as follows:

GLOSSARY OF SHADED TERMS

     Eligible Fund. An Eligible Fund is any Lord  Abbett-sponsored fund offering
     Class Y shares.

     Eurodollar.  Eurodollars are U.S. currency held in banks outside the United
     States,  mainly in Europe,  and commonly  used for  settling  international
     transactions.  Some securities are issued in  Eurodollars--that  is, with a
     promise to pay interest in dollars deposited in foreign bank accounts.

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

     To give another example,  if a redemption request were to be made on behalf
     of the ABC Corporation by a person (Mary B. Doe) who has the legal capacity
     to act on 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.



RECENT PERFORMANCE


     The  following is a discussion of recent  performance  for the twelve month
     period ending each Fund's respective fiscal year.

     Affiliated  Fund.  The past  fiscal  year which ended October 31, 1999 was
     characterized  by  continued
     overall strength in both the broad equity market and the U.S. economy.  Low
     interest rates and a deceleration  in earnings have driven the U.S.  equity
     market for the last two and one-half years. This environment favored a very
     select group of large stocks that have had stable earnings  growth.  Rather
     than  venturing  into  "unknown"  waters,  investors  stayed the course and
     continued to purchase names familiar to them, remaining with companies that
     exhibited strong earnings stories. The result, however, is that many of the
     larger,  more well-known  growth names have become,  in our opinion,  quite
     expensive.

     In anticipation  of an improvement in the global economy,  we made an early
     entry into the energy  sector,  a strategy that paid off well for the Fund.
     In our view, the rise in oil prices  initiated by OPEC,  coupled with solid
     fundamentals  for many energy  companies,  helped to boost this sector.  In
     addition, the technology sector continued to outperform the general market.
     However, despite strong performance by a number of holdings in this sector,
     we recently began to reduce our exposure to technology,  as prices began to
     reach the upper  end of our  valuation  discipline.  We  reinvested  a good
     portion of the  proceeds  from those sales into more  traditional  cyclical
     sectors such as paper,  chemicals and aluminum,  and anticipate these areas
     will  benefit  from a rise  in  commodity  prices  as  the  global  economy
     strengthens.

<PAGE>


     In addition,  we have started to focus some  attention  toward the property
     and casualty insurance sector during this period, and will continue to seek
     out companies in this market segment that display  improving  fundamentals.
     At the same time, we are generally  underweighted  in financial  companies,
     which has worked to our advantage  since many of these stocks  continued to
     struggle during this period as interest rates  increased.  We believe there
     is only a small  chance that U.S.  interest  rates will  continue to climb.
     This view, coupled with the fact that many financial service companies have
     solid  fundamentals,  will likely  result in an increase in our exposure to
     the financial services area.

     Growth Opportunities Fund. The stock market rebounded sharply in the fourth
     quarter ended November 30, 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 the period, 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
     telecommunication  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.

     High Yield  Fund.  Lord  Abbett  High Yield  Fund's  strategy is to build a
     portfolio of high-yield  bonds from companies with strong earnings that are
     well  managed  and are  undervalued  relative  to  their  fundamentals.  In
     the fiscal year ended November 30, 1999, we
     continued to find value among companies in the cable, media, technology and
     telecommunications industries. With ongoing consolidation in these sectors,
     many companies exhibit strong earnings potential due to the growth in data,
     video and voice  services.  We  increased  our  exposure  to certain  basic
     industries  such  as  paper  companies,  and  increased  our  multinational
     technology   manufacturing  and  semiconductor  holdings,  which  exhibited
     visible  price  improvements  and have the potential to benefit from global
     economic growth.  We remained  underweighted in financial  companies (e.g.,
     banking, insurance), retail companies and other consumer-oriented companies
     that were hurt by fierce competition in their respective industries.

     International  Series.  During the last months of 1998, many of the world's
     financial  markets  began to signal a  possible  recovery  from a  two-year
     period of financial  crisis and global  deflation.  By mid 1999,  it became
     apparent that this recovery was real, as economic  indicators  pointed to a
     new phase of global economic expansion.

     In  the  international  equity  markets,  Europe,  which  remained  subdued
     throughout  much of the period,  rallied when recession fears proved false.
     In addition, many European companies posted  better-than-expected  earnings
     growth in late 1999 due to a solid local economy and a weak euro,  relative
     to the dollar and the yen, which boosted

     exports.  Japan,  which  benefited  from a series of  economic  initiatives
     during the period, continued to show signs of improvement,  as it attracted
     overseas  money on the strength of its  apparent  recovery and its relative
     importance to international investors.

     In its fiscal year ended October 31, 1999, the Fund  continued to implement
     its  investment  strategy of focusing on
     attractively  priced,  industry-dominant  companies with global  leadership
     potential.  During the period, the Fund remained overweighted in European
     and Canadian companies that demonstrated superior corporate earnings growth
     rates and attractive valuation levels relative to many companies in the Far
     East and emerging markets.  In general, we limited our exposure to Japanese
     companies in traditional, old-style industries such as steel, chemicals and
     paper, because we believe they require further corporate restructuring.  In
     addition,  the  sluggishness  of Japan's overall economy does not bode well
     for those  industries.  However,  the Fund has invested in select  Japanese
     companies  within  new-style  industries,  such as  telecommunications  and
     software.  Indeed,  a handful of these high-tech  issues have accounted for
     the majority of recent gains in the Japanese markets.

     Large-Cap  Series.  We attribute the solid performance of your portfolio in
     the fiscal year ended November 30, 1999 to
     several    factors.    First,    the   new   era   of    technology-related
     telecommunications  spawned  several  winning  stocks  for  the  portfolio.
     Second,  we sharply  reduced  our  exposure  to the  consumer  non-cyclical
     sector,  a group  whose  performance  was  poor  for the  year.  Third,  we
     increased our allocation in the basic materials  sector  (aluminum,  paper,
     chemicals, etc.), as we believe this sector contains significant value.

     Amidst merger and  acquisition  activity,  the performance of the financial
     sector weakened in 1999.  Valuations suffered as acquiring banks eventually
     found  it hard to both cut  costs  and grow  revenue.  Intense  competition
     forced  downward  earnings  revisions in the group and some of our holdings
     suffered as a result.

     Small-Cap Value Series.  Our exposure to technology and  telecommunications
     stocks helped the overall performance of the portfolio in the fiscal year
     ended November 30, 1999.  Additionally,  the
     portfolio benefited from the purchase of several hardware technology stocks
     that were depressed  earlier in the year,  but performed  quite well as the
     year  progressed.  When these stocks hit the target prices we had set, they
     were  sold and the  proceeds  were  used to  invest  in other  parts of the
     technology sector such as software and information technology services.

     Despite prospects of continuing  consolidation,  we remained  significantly
     underweighted in the financial sector. This paid off later as disappointing
     earnings drove small-cap financial stocks down.

(1)  Performance for each unmanaged index does not reflect any fees or expenses.
(2)  This shows total  return  which is the percent  change in net asset  value,
     with all  dividends  and  distributions  reinvested  for the periods  shown
     ending November 30, 1999 using the  SEC-required  uniform method to compute
     total return.  Because Class Y has less than one year of  performance,  the
     total returns shown are for Class A shares.  Returns for Class Y shares are
     expected to be somewhat higher than those of Class A shares because Class Y
     shares have lower expenses. The Class A share inception date is 8/1/95.

                               Investment Policies


Fundamental  Investment  Restrictions.  The Funds are  subject to the  following
investment  restrictions  which cannot be changed without approval of a majority
of each Fund's outstanding shares.

Each Fund may not:

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

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

Non-Fundamental   Investment   Restrictions.   In  addition  to  the  investment
restrictions above which cannot be changed without  shareholder  approval,  each
Fund also is subject to the following non-fundamental  investment policies which
may be  changed  by the  Boards  of  Directors  (Trustees)  without  shareholder
approval.

Each Fund may not:

(1)  borrow  in  excess of 33 1/3% of its total  assets  (including  the  amount
     borrowed),  and then  only as a  temporary  measure  for  extraordinary  or
     emergency purposes;
(2)  make short sales of securities or maintain a short  position  except to the
     extent permitted by applicable law;
(3)  invest  knowingly  more  than  15%  of its  net  assets  (at  the  time  of
     investment) in illiquid  securities,  except for securities  qualifying for
     resale under Rule 144A of the Securities  Act of 1933,  deemed to be liquid
     by the Boards of Directors (Trustees);

<PAGE>

(4)  invest in the securities of other investment companies as defined under 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 of 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 each Fund's officers
     or directors (trustees) or by one or more partners or members of the Fund's
     underwriter  or  investment  adviser if these owners in the  aggregate  own
     beneficially more than 5% of the securities of such issuer;
(7)  invest in warrants if, at the time of the  acquisition,  its  investment in
     warrants,  valued at the lower of cost or market,  would  exceed 5% of each
     Fund's total assets (included within such limitation,  but not to exceed 2%
     of each Fund's total assets,  are warrants  which are not listed on the New
     York or American Stock Exchange or a major foreign exchange);
(8)  invest in real estate  limited  partnership  interests or interests in oil,
     gas or other mineral leases, or exploration or other development  programs,
     except that each Fund may invest in  securities  issued by  companies  that
     engage  in oil,  gas or other  mineral  exploration  or  other  development
     activities;
(9)  write,  purchase or sell puts,  calls,  straddles,  spreads or combinations
     thereof,  except  to  the  extent  permitted  in a  Fund's  prospectus  and
     statement of  additional  information,  as they may be amended from time to
     time;
(10) buy  from  or  sell  to any of a  Fund's  officers,  directors  (trustees),
     employees, or its investment adviser any securities  other than shares of a
     Fund;
(11) with  respect to  Affiliated  Fund,  pledge,  mortgage or  hypothecate  its
     assets;  however,  this  provision  does not  apply to the  grant of escrow
     receipts or the entry into other similar escrow arrangements arising out of
     the writing of covered call options; and
(12) with  respect to High Yield Fund,  invest more than 10% of the market value
     of its gross assets at the time of investment in debt securities  which are
     in default as to interest or principal.

For the year ended October 31, 1999,  Affiliated Fund's portfolio  turnover rate
was 62.30%  versus  56.49% for the prior year.  For the year ended  November 30,
1999,  the  Small-Cap  Value Series'  portfolio  turnover rate was 83.93% versus
67.86% for the prior year; and the Large-Cap Series' portfolio turnover rate was
60.59%  versus  99.14% for the prior year.  For the year ended October 31, 1999,
the International  Series' portfolio  turnover rate was 75.15% versus 20.52% for
the year ended  October 31, 1999.  For the year ended  November  30,  1999,  the
Growth  Opportunities  Fund's  turnover rate was 104.87%  versus 136.81% for the
prior year.

With respect to the Affiliated  Fund, it has no current  intention to do so, but
may invest in financial futures & options on financial futures.


INVESTMENT TECHNIQUES

Lending  Portfolio  Securities  (Affiliated  Fund,  Growth  Opportunities  Fund,
International  Series,  Large-Cap Series,  Small-Cap Value Series) The Funds may
lend  portfolio  securities  to registered  broker-dealers.  These loans may not
exceed  30%  of  total  assets.   The  Funds'  loans  of   securities   will  be
collateralized by cash or marketable securities issued or guaranteed by the U.S.
Government or its agencies ("U.S.  Government  Securities") or other permissible
means. The cash or instruments  collateralizing  the loans of securities will be
maintained at all times in an amount at least equal to the current  market value
of the loaned securities. From time to time, the Funds may allow to the borrower
and/or a third  party that is not  affiliated  with the Funds and is acting as a
"placing broker" a part of the interest  received with respect to the investment
of collateral  received for securities loaned. No fee will be paid to affiliated
persons of the Funds.

By  lending  portfolio  securities,  the  Funds  can  increase  their  income by
continuing  to receive  interest on the loaned  securities  as well as by either
investing  the  cash  collateral  in  permissible  investments,   such  as  U.S.
Government  Securities,  or obtaining  yield in the form of interest paid by the
borrower when such U.S. Government Securities are used as collateral.  The Funds
will comply with the following  conditions  whenever they loans securities:  (i)
the Funds must  receive at least 100%  collateral  from the  borrower;  (ii) the
borrower  must  increase  the  collateral  whenever  the  market  value  of  the
securities loaned rises above the level of the collateral;  (iii) the Funds must
be able  to  terminate  the  loan at any  time;  (iv)  the  Funds  must  receive
reasonable  compensation  with  respect to the loan,  as well as any  dividends,
interest or other distributions on the loaned securities;  (v) the Funds may pay
only  reasonable  fees in connection with the loan and (vi) voting rights on the
loaned  securities  may pass to the borrower  except that,  if a material  event
adversely  affecting the investment in the loaned securities  occurs, the Funds'
Board must terminate the loan and regain the right to vote the securities.

<PAGE>

Rule  144A  Securities  (Affiliated  Fund)  The Fund may  invest  in  securities
qualifying  for resale to "qualified  institutional  buyers" under SEC Rule 144A
that are  determined  by the Board,  or by Lord  Abbett  pursuant to the Board's
delegation,  to be  liquid  securities.  The Board  will  review  quarterly  the
liquidity of the investments the Fund makes in such  securities.  Investments by
the Fund in Rule 144A  securities  initially  determined to be liquid could have
the effect of diminishing  the level of the Fund's  liquidity  during periods of
decreased  market  interest in such  securities  among  qualified  institutional
buyers.

Other Investment Policies  (Affiliated Fund and Large-Cap Series) Both Funds may
write  covered call options which are traded on a national  securities  exchange
with respect to securities in our portfolio in an attempt to increase income and
to provide  greater  flexibility in the disposition of portfolio  securities.  A
"call option" is a contract sold for a price (the  "premium")  giving its holder
the right to buy a specific  number of shares of stock at a specific price prior
to a  specified  date.  A  "covered  call  option"  is a call  option  issued on
securities  already  owned by the writer of the call option for  delivery to the
holder upon the exercise of the option.  During the period of the option, a Fund
will forgo the  opportunity  to profit from any  increase in the market price of
the  underlying  security  above the exercise price of the option (to the extent
that the  increase  exceeds our net  premium).  We also may enter into  "closing
purchase  transactions"  in order to  terminate  the  obligation  to deliver the
underlying  security  (this may result in a short-term  gain or loss). A closing
purchase  transaction  is the  purchase of a call option (at a cost which may be
more or less than the premium  received for writing the original call option) on
the same  security,  with the same exercise  price and call period as the option
previously  written.  If a Fund is  unable  to  enter  into a  closing  purchase
transaction,  it may be required to hold a security that it might otherwise have
sold to protect  against  depreciation.  A Fund does not intend to write covered
call options with respect to securities  with an aggregate  market value of more
than 10% of its gross assets at the time an option is written.  This  percentage
limitation  will not be increased  without prior  disclosure in a Fund's current
Prospectus.

Repurchase Agreements  (International Series) The Fund may enter into repurchase
agreements with respect to a security.  A repurchase  agreement is a transaction
by which the 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 the  Fund  have a  total  value  in  excess  of the  value  of the
repurchase  agreement.  The 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 the Fund to keep all of its  assets at work  while  retaining
flexibility in pursuit of investments of a longer term nature.

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.


                                       4


<PAGE>

The Fund will enter into repurchase agreements only with those primary reporting
dealers  that  report to the Federal  Reserve  Bank of New York and with the 100
largest United States commercial banks and the underlying  securities  purchased
under the  agreements  will consist only of those  securities  in which the Fund
otherwise may invest.

Warrants   (International   Series  and  Large-Cap  Series)  Pursuant  to  Texas
regulations,  both Funds 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, we will not invest more than 5% of our net assets
in rights.

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

The Funds' custodian will segregate cash or liquid high-grade debt securities in
an amount not less than that  required by  Securities  and  Exchange  Commission
("SEC")  Release  10666 with respect to the Funds'  assets  committed to written
covered  call  options.  If the  value of the  segregated  securities  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 Funds' commitments with respect to such written options.

Financial  Futures  Contracts  (International  Series and Large-Cap Series) Both
Funds  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 we hold or intend
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. Both Funds will not enter
into any futures  contracts or options on futures  contracts if the aggregate of
the market value of the securities covered by its outstanding  futures contracts
and securities  covered by futures contracts subject to the outstanding  options
written by it would exceed 50% of its total assets.

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

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

Options on  Financial  Futures  Contracts  (International  Series and  Large-Cap
Series)  Both Funds may  purchase  and write call and put  options on  financial
futures  contracts.  An option on a futures  contract  gives the  purchaser  the
right,  in  return  for the  premium  paid,  to assume a  position  in a futures
contract  at a  specified  exercise  price at any time  during the period of the
option. Upon exercise, the writer of the option delivers the futures contract to
the holder at the exercise  price.  Both Funds would be required to deposit with
our custodian initial margin and maintenance margin with respect to put and call
options on futures contracts written by us. 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 that a Fund intends to
hedge (or  protect)  against  not  materialize,  however,  the option may expire
worthless, in which case the Fund would lose the premium paid therefor.

Segregated  Accounts  (International  Series and Large-Cap Series) To the extent
required to comply with Securities and Exchange Commission Release 10666 and any
related SEC  policies,  when  purchasing  a futures  contract,  or writing a put
option,  each Fund will maintain in a segregated  account at its custodian  bank
cash, U.S. Government and other permitted securities to cover its position.

Forward Foreign Currency Contracts (Growth  Opportunities Fund,  Small-Cap Value
Series,) 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.  Each Fund expects to enter into  forward  foreign  currency  contracts in
primarily two  circumstances.  First, when a Fund enters into a contract for the
purchase or sale of a security denominated in a foreign currency,  it may desire
to "lock in" the U.S.  dollar price of the security.  By entering into a forward
contract for the purchase or sale of the amount of foreign currency  involved in
the underlying security transaction, each Fund will be able to protect against a
possible loss resulting from an adverse change in the  relationship  between the
U.S. dollar and the subject foreign  currency during the period between the date
the  security  is  purchased  or sold and the date on which  payment  is made or
received.

Second,  when  management  believes  that the currency of a  particular  foreign
country may suffer a decline against the U.S. dollar, each Fund may enter into a
forward contract to sell the amount of foreign currency  approximating the value
of some or all of each Fund's portfolio  securities  denominated in such foreign
currency or, in the  alternative,  each Fund may use a  cross-hedging  technique
whereby  it sells  another  currency  which  each 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.  Each Fund  does not  intend  to enter  into such  forward
contracts under this second circumstance on a continuous basis.


                                       6


<PAGE>

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

Foreign Currency Hedging Techniques (Growth  Opportunities Fund, Small-Cap Value
Series) The Funds may  utilize  various  foreign  currency  hedging  techniques,
including  forward foreign currency  contracts and foreign currency put and call
options.

Foreign  Currency Put and Call Options  (Growth  Opportunities  Fund,  Small-Cap
Value Series) The Funds 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 the Funds, upon payment of a premium,  the right to
sell a currency at the  exercise  price until the  expiration  of the option and
serves to insure  against  adverse  currency  price  movements in the underlying
portfolio assets denominated in that currency.

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

A call option written by a Fund gives the purchaser,  upon payment of a premium,
the right to  purchase a  currency  at the  exercise  price  until the
expiration of the option. The Funds may write call options 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 the Funds or in such cross currency (referred to above) to cover such call
writing.

The Funds'  custodian will segregate cash or permitted  securities  belonging to
the Funds in an amount  not less than that  required  by SEC  Release  10666 and
related  policies  with  respect to the Funds'  assets  committed to (a) writing
options,  (b) forward  foreign  currency  contracts and (c) cross hedges entered
into  by  the  Funds.  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 Funds'  commitments  with respect to such written  options,  forward foreign
currency contracts and cross hedges.

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

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


                                       7


<PAGE>

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

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

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

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

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

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

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

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

Segregated  Accounts  (Small-Cap Value Series) If the Fund has written an option
on an industry or market  segment  index,  it will  segregate or put into escrow
with its custodian, or pledge to a broker as collateral for the option, at least
ten "qualified  securities,"  which are securities of an issuer in such industry
or market segment,  with a market value at the 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 Fund has not written a
stock call option and which has not been hedged by the Fund 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  Fund's  holdings  in that  industry  or  market  segment.  No
individual  security will  represent  more than 25% of the amount so segregated,
pledged or escrowed.  If at the close of business on any day the market value of
such qualified securities so segregated, escrowed or pledged falls below 100% of
the current index value times the multiplier times the number of contracts,  the
Fund will so segregate,  escrow or pledge an amount in cash,  Treasury  bills or
other high-grade  short-term  obligations  equal in value to the difference.  In
addition,  when the Fund writes a call on an index which is  in-the-money at the
time the call is written,  the Fund 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 Fund holds a call on
the same index as the call written where the exercise  price of the call held is
equal to or less than the exercise price of the call written or greater than the
exercise  price of the call written if the  difference is maintained by the Fund
in cash, equity securities,  non-investment  grade debt, treasury bills or other
high-grade short-term obligations in a segregated account with its custodian, it
will not be subject to the requirements describe in this paragraph. In instances
involving the purchase of stock index  futures  contracts by the Fund, an amount
of cash or  permitted  securities  equal  to the  market  value  of the  futures
contracts  will be  deposited in a  segregated  account  with its  custodian
and/or in a margin  account  with a broker to  collateralize  the  position  and
thereby insure that the use of such futures are unleveraged.

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

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

RISK FACTORS

Risk Factors (Affiliated Fund) As stated in the Prospectus,  the Fund may invest
no more than 5% of its net assets (at the time of  investment)  in  lower-rated,
high-yield  bonds. In general,  the market for lower-rated,  high-yield bonds is
more limited than the market for higher-rated bonds, and because trading in such
bonds may be  thinner  and less  active,  the  market  prices of such  bonds may
fluctuate more than the prices of higher-rated  bonds,  particularly in times of
market  stress.  In addition,  while the market for  high-yield,  corporate debt
securities  has been in  existence  for many years,  the market in recent  years
experienced a dramatic  increase in the  large-scale  use of such  securities to
fund highly-leveraged  corporate  acquisitions and restructurings.  Accordingly,
past experience may not provide an accurate  indication of future performance of
the high-yield  bond market,  especially  during periods of economic  recession.
Other risks which may be associated with  lower-rated,  high-yield bonds include
their relative  insensitivity to interest-rate  changes;  the exercise of any of
their  redemption or call  provisions in a declining  market which may result in
their replacement by lower-yielding  bonds; and legislation,  from time to time,
which may  adversely  affect their  market.  Since the risk of default is higher
among lower-rated,  high-yield bonds, Lord Abbett's research and analyses are an
important   ingredient  in  the  selection  of  such  bonds.  Through  portfolio
diversification,  good credit analysis and attention to current developments and
trends  in  interest  rates  and  economic  conditions,  investment  risk can be
reduced,  although  there is no assurance  that losses will not occur.  The Fund
does  not  have any  minimum  rating  criteria  applicable  to the  fixed-income
securities in which it invests.

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

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

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

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

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

<PAGE>

Special  Risks of Writing  Calls on Indices  (Small-Cap  Value  Series)  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  Fund  will  write  call   options  on  indices  only  under  the
circumstances  described above under  "Limitations on the Purchases and Sales of
Stock Options, Options on Stock Indices and Stock Index Futures."

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

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

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

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

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

2. The amounts  were accrued by the Lord  Abbett-sponsored  funds for the twelve
   months  ended  October  31,  1999 with  respect  to the  equity  based  plans
   established  for  independent  directors  in 1996.  This  plan  supercedes  a
   previously  approved  retirement  plan for all  future  directors.  Directors
   participating  in the retirement plan had the option to convert their accrued
   benefits under the plan. All of the outside directors except one made such an
   election.  Each plan also  provides for a  pre-retirement  death  benefit and
   actuarially reduced joint-and-survivor spousal benefits.

3. This table shows aggregate  compensation,  including  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 have chosen to defer) but
   does not include amounts accrued under the equity based plan.. The amounts of
   the aggregate compensation payable as of each of their respective 1999 fiscal
   year ends deemed invested in Fund shares,  including dividends reinvested and
   changes in net asset value applicable to such deemed investments were:

Lord Abbett has entered into an agreement  with Fuji-Lord  Abbett  International
Ltd. ("the Sub-Adviser"),  under which the Sub-Adviser provides Lord Abbett with
advice with respect to the  International  Series'  assets.  The  Sub-Adviser is
controlled  by Fuji  Investment  Management  Co.  (Tokyo).  Fuji Bank Limited of
Tokyo, Japan ("Fuji Bank") directly owned 40% of the outstanding voting stock of
the Sub-Adviser.  Fuji Investment Management Co. (Tokyo) is an affiliate of Fuji
Bank. Lord Abbett owns approximately 27% of such outstanding voting stock. As of
November 30, 1999, the Sub-Adviser manages approximately $915 million,  which is
invested  globally.  The  Sub-Adviser  furnishes  Lord  Abbett  with  advice and
recommendations  with respect to the  International  Series'  assets,  including
advice about the allocation of investments among foreign  securities markets and
foreign  equity  and  debt  securities  markets  and  foreign  equity  and  debt
securities  and,  subject to  consultation  with Lord Abbett,  advice as to cash
holdings and what  securities  in the  portfolio  should be  purchased,  held or
disposed of. The Sub-Adviser  also gives advice with respect to foreign currency
matters. Lord Abbett is obligated to pay the Sub-Adviser a monthly fee, based on
average  daily net assets for each month,  at the annual rate of .375 of 1%. For
the fiscal  year ended  October  31,  1999,  October 31, 1998 and for the period
December 13, 1996  (commencement  of  operations)  to October 31, 1997, the fees
paid  to  the  Sub-Adviser  by  Lord  Abbett  were  $ ,  $350,184  and  $63,857,
respectively.

Each  Fund's fee is  allocated  among all of its  classes  based on each  Fund's
proportionate share of such daily net assets.

In addition, each Fund is obligated to pay all expenses not expressly assumed by
Lord  Abbett,  including,  without  limitation,   outside  directors'  fees  and
expenses,  association membership dues, legal and auditing fees, taxes, transfer
and  dividend  disbursing  agent fees,  shareholder  servicing  costs,  expenses
relating to shareholder  meetings,  expenses of preparing,  printing and mailing
stock certificates and shareholder  reports,  expenses of registering our shares
under federal and state  securities  laws,  expenses of preparing,  printing and
mailing prospectuses to existing shareholders, insurance premiums, brokerage and
other expenses connected with executing portfolio transactions.

Deloitte & Touche LLP, Two World Financial Center,  New York, New York 10281 are
the independent auditors for each Fund and must be approved at least annually by
each Fund's Board of Directors  (Trustees)  to continue in such  capacity.  They
perform  audit  services  for  each  Fund  including  the  audits  of  financial
statements included in each Fund's annual report to shareholders.

                             Portfolio Transactions

Our policy is to obtain best execution on all our portfolio transactions,  which
means that we seek to have purchases and sales of portfolio  securities executed
at the most favorable prices, considering all costs of the transaction including
brokerage  commissions  and dealer markups and markdowns and taking into account
the full range and quality of the brokers'  services.  Consistent with obtaining
best execution,  we generally pay, as described below, a higher  commission than
some brokers might charge on the same  transactions.  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 Fund and also are employees
of Lord  Abbett.  These  traders do the  trading as well for other  accounts  --
investment  companies  (of which they are also  officers)  and other  investment
clients -- managed by Lord  Abbett.  They are  responsible  for  obtaining  best
execution.

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

Some of these brokers also provide research  services at least some of which are
useful to Lord Abbett in their overall  responsibilities  with respect to us and
the other accounts they manage. Research includes the furnishing of analyses and
reports concerning issuers, industries, securities, economic factors and trends,
portfolio  strategy and the  performance  of accounts and trading  equipment and
computer software  packages,  acquired from third-party  suppliers,  that enable
Lord Abbett to access various information  databases.  Such services may be used
by Lord Abbett in servicing  all their  accounts,  and not all of such  services
will  necessarily be used by Lord Abbett in connection with their  management of
the Fund;  conversely,  such services  furnished in connection with brokerage on
other  accounts  managed  by Lord  Abbett may be used in  connection  with their
management of the Fund, and not all of such services will necessarily be used by
Lord Abbett in connection  with their advisory  services to such other accounts.
We have been advised by Lord Abbett that research services received form 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, and 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.


                                       19


<PAGE>

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 Lord Abbett to purchase or sell portfolio securities.

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

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

For the fiscal years ended October 31, 1999, 1998 and 1997, Affiliated Fund paid
total  commissions to  independent  dealers of  $11,088,462 ,  $12,832,030,  and
$7,681,037, respectively.

For the fiscal year ended November 30, 1999, 1998 and 1997, Growth Opportunities
Fund  paid  total  commissions  to  independent  broker-dealers  of $  91,960 ,
$12,741, and $3,678, respectively.

For the fiscal year ended  October 31,  1999,  1998 and the period  December 13,
1996 (commencement of operations) through October 31, 1997, International Series
paid total commissions to independent  broker-dealers  of $ 380,452,  $321,480
and $108,281, respectively.

For the fiscal years ended  November 30, 1999,  1998,  and 1997,  the  Large-Cap
Series  paid  total  commissions  to  independent  broker-dealers  of $395,908,
$321,279 and $88,234, respectively.

For the fiscal years ended  November 30, 1999,  1998,  and 1997,  the  Small-Cap
Value Series paid total  commissions to independent broker-dealers of $1,492,501
$1,564,340, and $1,812,425, respectively.

                             Purchases, Redemptions
                            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.


                                       20

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

The net asset  value per share  for the  Class Y shares  will be  determined  by
taking Class Y shares net assets and dividing by shares outstanding. Our Class Y
shares will be offered at net asset value.

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

Class Y  Share  Exchanges.  The  Prospectus  describes  the  Telephone  Exchange
Privilege.  You may  exchange  some or all of your Y shares  for Y shares of any
Lord  Abbett-sponsored  funds  currently  offering Class Y shares to the public.
Currently those other funds consist of Lord Abbett Investment Trust - Core Fixed
Income  Series,  Strategic  Core  Fixed  Income  Series,   Bond-Debenture  Fund,
Developing Growth Fund, and Mid-Cap Value Fund.

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

The right to redeem and receive payment, as described in each 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  /Trustees may authorize  redemption of all of the shares
in any account in which there are fewer than 25 shares  (Affiliated Fund, Growth
Opportunities  Fund,  High Yield Fund,  Large-Cap  Series,  and Small-Cap  Value
Series),  and  60  shares  (International   Series).   Before  authorizing  such
redemption, the Board must determine that it is in our economic best interest or
necessary  to  reduce   disproportionately   burdensome  expenses  in  servicing
shareholder  accounts.  At least 6 months  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.

                                       6.
                                      Taxes

The value of any shares  redeemed by each Fund or  repurchased or otherwise sold
may be  more  or  less  than  your  tax  basis  in the  shares  at the  time  of
disposition. Any gain will generally be taxable for federal income tax purposes.
Any loss realized on the  disposition of a Fund's shares which you have held for
six months or less will be treated for tax purposes as a long-term  capital loss
to the extent of any  "capital  gains  distributions"  which you  received  with
respect  to such  shares.  Losses on the sale of shares are not  deductible  if,
within a period beginning 30 days before the date of the sale and ending 30 days
after the date of the sale, the taxpayer  acquires shares that are substantially
identical.


                                       21


<PAGE>

Each Fund will be subject to a four-percent  nondeductible 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.

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

Each Fund may be subject to foreign  withholding  taxes which  would  reduce the
yield on its investments.  It is generally  expected that shareholders of a Fund
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
such Fund.  However,  if at the close of any fiscal  year,  more than 50% of the
assets of a fund consist of stock or  securities  of foreign  corporations,  the
Fund may elect to treat  foreign  income  taxes paid by the Fund as having  been
paid  directly  by its  shareholder.  If a Fund  makes  such  an  election,  the
shareholders  of the Fund will be  required  to (I)  include in  ordinary  gross
income (in addition to taxable dividends actually received) their pro rata share
of foreign  income  taxes paid by the Fund and (ii) treat such pro rata share as
foreign income taxes paid by them. Such  shareholders may then use such pro rata
portion of foreign  income taxes as foreign tax credits,  subject to  applicable
limitations,  or, alternatively,  deduct them in computing their taxable income.
Shareholders who do not itemize  deductions for federal income tax purposes will
not be entitled to deduct  their pro rata  portion of foreign  taxes paid by the
Fund,  although such  shareholders will still be required to include their share
of such taxes in gross income.  Shareholders  who claim a foreign tax credit for
foreign taxes paid by a Fund may be required to treat a portion of the dividends
received from the Fund as separate category income for purposes of computing the
limitations on the foreign tax credit.  Tax-exempt  shareholders will ordinarily
not benefit from this  election.  Each year that a Fund  qualifies for and makes
the election described above, its shareholders will be notified of the amount of
(i) each  shareholder's  pro rata share of foreign income taxes paid by the Fund
and (ii) the portion of  dividends  which  represents  income from each  foreign
country.

Gains and losses realized by each 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 gains or losses are  attributable  to changes in
exchange rates for foreign  currencies.  Accordingly,  distributions  taxable as
ordinary  income will include the net amount,  if any, of such foreign  exchange
gains and will be reduced by the net amount,  if any, of such  foreign  exchange
losses.

If either Fund purchases shares in certain foreign investment  entities,  called
"passive  foreign  investment  companies,"  it 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 either  the Fund or its  shareholders  in respect to
deferred taxes arising from such distributions or gains.

If a Fund were to invest in a passive foreign investment company with respect to
which a Fund elected to make a "qualified  electing fund"  election,  in lieu of
the foregoing requirements, the Fund might be required to include in income each
year a portion of the ordinary  earnings and net capital  gains of the qualified
electing fund, even if such amount were not distributed to a Fund.

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.

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 advisor
regarding  U.S.  and foreign tax  consequences  of the  ownership of shares of a
Fund,  including a 30% (or lower treaty rate) United States  withholding  tax on
dividends representing ordinary income and net short-term capital gains, and the
applicability  of United States gift and estate taxes to non-United  States gift
and estate taxes to non-United States persons who own Fund shares.

                                Past Performance

Each Fund computes the annual compounded rate of total return for Class Y shares
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 no sales charge from the initial amount  invested and  reinvestment
of all income  dividends and capital  gains  distributions  on the  reinvestment
dates at prices  calculated as stated in each Prospectus.  The ending redeemable
value  is  determined  by  assuming  a  complete  redemption  at the  end of the
period(s) covered by the annual total return computation.

In calculating total returns for Class Y shares no sales charge is deducted from
the initial investment and the 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.

Class Y  share  performance.  Using  the  computation  method  described  above,
Affiliated  Fund's  total  return for Class Y shares  for the fiscal  year ended
October 31, 1999 was %. Small-Cap  Value Series' total return for Class Y shares
for the fiscal year ended  November  30,  1999 %.  International  Series'  total
return for Class Y shares for the fiscal year ended  October 31, 1999 was %. All
of these returns are not annualized.

Our yield  quotation  for Class Y shares is based on a 30-day  period ended on a
specified date,  computed by dividing the net investment income per share earned
during the period by the net asset value per share of such class on the last day
of the period.  This is determined by finding the following  quotient:  take the
dividends and interest earned during the period for the class minus its expenses
accrued for the period and divide by the product of (i) the average daily number
of Class  shares  outstanding  during the period  that were  entitled to receive
dividends  and (ii) the net asset  value 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.Yields  for Class Y shares do not reflect the
deduction of any sales charge.

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.

                           Information About the Funds

Affiliated  Fund is a  Maryland  Corporation  formed  in 1934.  Small-Cap  Value
Series,  Large-Cap Series and Growth Opportunities Fund are Funds of Lord Abbett
Research Fund, Inc., a Maryland corporation organized in 1992. The International
Series is a Fund of Lord Abbett  Securities  Trust,  a Delaware  business  trust
organized  in 1993.  The High  Yield  Fund is a Fund of Lord  Abbett  Investment
Trust, a Delaware business trust organized in 1993.

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



Our Boards of Directors/Trustees have authority to create and classify shares in
separate series, without further action by shareholders.  To date, the Boards of
Directors/Trustees  have  authorized five classes of shares for each Fund (Class
A, B, C, P and Y). The Board of a Fund will  allocate a Fund's  shares among its
classes from time to time. All shares of a Fund have equal noncumulative  voting
rights and equal  rights  with  respect to  dividends,  assets and  liquidation,
except  for   certain   class-specific   expenses.   They  are  fully  paid  and
nonassessable when issued and have no preemptive or conversion rights.  Although
no present plans exist to do so,  further  classes or series may be added to one
or more of the Funds in the future.  The Act  requires  that where more than one
series exists for a Fund, each series must be preferred over all other series in
respect of assets specifically allocated to such series.


Rule 18f-2 under the Act provides that any matter  required to be submitted,  by
the provisions of the Act or applicable  state law or otherwise,  to the holders
of the  outstanding  voting  securities of an investment  company such as a 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 or series affected
by such  matter.  Rule 18f-2  further  provides  that a class or series shall be
deemed to be affected by a matter  unless the  interests of each class or series
in the  matter are  substantially  identical  or the matter  does not affect any
interest of such class or series.  However,  the Rule  exempts the  selection of
independent public accountants, the approval of principal distribution contracts
and the election of directors from the separate voting requirements of the Rule.
Shareholder  inquiries  should be made by  writing  directly  to your Fund or by
calling  800-821-5129.  In addition,  you can make inquiries through Lord Abbett
Distributor.

               None.

Item 25        Indemnification
               ---------------

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

               The  general  effect of these  statutes  is to protect  officers,
               directors and employees of Registrant against legal liability and
               expenses   incurred  by  reason  of  their   positions  with  the
               Registrant.   The  statutes  provide  for   indemnification   for
               liability   for   proceedings   not  brought  on  behalf  of  the
               corporation  and for those brought on behalf of the  corporation,
               and in each case place  conditions  under  which  indemnification
               will be  permitted,  including  requirements  that  the  officer,
               director  or  employee   acted  in  good  faith.   Under  certain
               conditions,  payment of expenses in advance of final  disposition
               may be permitted. The By-laws of Registrant, without limiting the
               authority  of  Registrant  to  indemnify  any  of  its  officers,
               employees or agents to the extent consistent with applicable law,
               make the  indemnification of its directors mandatory subject only
               to the conditions and limitations imposed by the above- mentioned
               Section  2-418 of Maryland law and by the  provisions  of Section
               17(h) of the Investment  Company Act of 1940 as  interpreted  and
               required  to be  implemented  by  SEC  Release  No.  IC-11330  of
               September 4, 1980.


<PAGE>

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

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

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

Lord Abbett Affiliated Fund, Inc.
90 Hudson Street
Jersey City, NJ 07302-3972

Dear Sirs:

     You have requested our opinion in connection  with your filing of Amendment
No. 87 to the Registration  Statement on Form N-1A (the  "Amendment")  under the
Investment  Company  Act of  1940,  as  amended  (the  "Act"),  of  Lord  Abbett
Affiliated Fund, Inc., a Maryland Corporation (the "Company"), and in connection
therewith your  registration of Class A, B, C, P, and Y shares of capital stock,
with a par value of $.001 each, of the Company (collectively, the "Shares").

     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 Act or the rules and regulations of the Securities and Exchange
Commission thereunder.

                              Very truly yours,


                              WILMER, CUTLER & PICKERING
                              By:___________________________
