                                                                 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 market values between $1 billion and $10 billion.
     The  Fund  uses a growth  style  of  investing  which  means  that we favor
     companies  that show the potential  for stronger than expected  revenue and
     earnings  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.

     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  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.

     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.

                                                                     The Funds 7


<PAGE>


                                                                 High Yield 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

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.

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.  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 management  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.

                                                            International Series

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.

<PAGE>

                                                                Large-Cap Series

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.

Bargain stocks are stocks of com-panies which we believe the market  undervalues

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

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.

                                                          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.

     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 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.

     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.

PURCHASES

     Class Y shares.  You may  purchase  Class Y shares  at the net asset  value

     in writing.

     Who May Invest?  Eligible purchasers of Class Y shares include: (1) certain
     authorized  brokers,  dealers,  registered  investment  advisers  or  other
     financial institutions ("entities") who either (a) have an arrangement with
     Lord Abbett  Distributor in accordance with certain  standards  approved by
     Lord Abbett Distributor,  providing specifically for the use of our Class Y
     shares  in  particular  investment  products  made  available  for a fee to

     Abbett  or  its  sub-advisers  on  a  private-advisory-account  basis;  (3)
     institutional investors, such as retirement plans, companies,  foundations,
     trusts,  endowments  and other entities where the total amount of potential
     investable  assets  exceeds $50 million  that were not  introduced  to Lord
     Abbett by persons  associated with a broker or dealer primarily involved in
     the retail  securities  business.  Additional  payments may be made by Lord
     Abbett out of its own resources with respect to certain of these sales.

     How Much Must You Invest?  You may buy our shares  through any  independent
     securities  dealer having a sales  agreement with Lord Abbett  Distributor,
     our exclusive  selling agent.  Place your order with your investment dealer

     prior to the close of the NYSE,  or received by dealers prior to such close
     and received by Lord Abbett  Distributor prior to the close of its business
     day, will be confirmed at NAV effective at such NYSE close. Orders received
     by dealers after the NYSE closes and received by Lord Abbett Distributor in
     proper form prior to the close of its next business day are executed at the

     Normally  a check  will be  mailed  to the name and  address  in which  the

     as permitted by federal securities laws.

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.

     Fund's team,  the other senior member of which is Gregory M.  Macosko.  Mr.
     Fetch  joined  Lord  Abbett in 1995;  prior to that,  he was was a Managing
     Director of Prudential  Investment  Advisors from 1983 to 1995. Mr. Macosko
     joined Lord  Abbett in 1996;  prior to that he was an Equity  Analyst  with
     Quest Advisory Service from 1991 to 1996.

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 Fund other than the High Yield Fund
     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 may  invest  no 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 Each Fund other than the High Yield Fund 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.  The Funds may invest
     in sponsored and unsponsored Depository Receipts.

     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 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


24 For More Information


<PAGE>


     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.  A financial  futures
     transaction  is an  exchange-traded  contract  to  buy or  sell a  standard
     quantity  and  quality  of a  financial  instrument  or index at a specific
     future date and price.  Each Fund may purchase  and sell futures  contracts
     and  options  thereon.  Each Fund  other  than the High Yield Fund will not
     enter into any  futures  contracts  or options  thereon,  if the  aggregate
     market value of the securities covered by such contracts exceeds 50% of the
     Fund's total  assets.  The High Yield Fund may not invest more than 5%
     of its assets in such transactions.

     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 International 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  the
     International  Series  does  not  normally  engage  in  extensive  currency
     hedging,  it 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  will 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 Fund's  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 the 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  International  Series to  fluctuate.  Currency  exchange  rates may be
     affected  unpredictably by the intervention of U.S. or foreign  governments
     or 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,   Large-Cap  Series,   Growth
     Opportunities Fund, and Small-Cap Value Series will limit their investments
     in  foreign  securities  to 10%  of  their  respective  total  assets.  The
     International  Series may  invest all of its assets in foreign  securities.
     The High Yield Fund will limit such investments to 20% of its total assets.
     Foreign  markets and the  securities  traded in them are not subject to the
     same  degree  of  regulation  as U.S.  markets.  Securities  clearance  and
     settlement  procedures may be different in foreign countries.  There may be
     less trading volume in foreign markets, subjecting the securities traded in
     them to  higher  price  fluctuations.  Transaction  costs  may be higher in
     foreign  markets.  A Fund may hold foreign  securities  which trade on days
     when the Fund does not sell  shares.  As a result,  the value of the Fund's
     portfolio  securities  may change on days an investor  may not  purchase or
     sell Fund shares.

     Foreign issuers are generally not subject to similar,  uniform  accounting,
     auditing and


                                                         For More Information 25


<PAGE>

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

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

     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 the Funds may only sell call  options  on  securities  which the Funds
     own. When a Fund writes a call option it gives up the potential for gain on
     the  underlying  securities  in excess of the exercise  price of the option
     during  the  period   that  the  option  is   open. The Affiliated   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  International  Series'  and
     Large-Cap Series' gross assets. In addition,  the Growth Opportunities Fund
     may write covered call options on securities having an aggregate market not
     to exceed 5% of that fund's 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.  Transactions 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 assets being hedged,
     the potential illiquidity of the markets for derivative instruments, or the
     risks  arising  from  margin  requirements  and  related  leverage  factors
     associated with such transactions.  The use of these investment  techniques
     also involves the risk of loss if the  portfolio  managers are incorrect in
     their expectation of fluctuations in securities

     prices.  In  addition,  the  loss  that  may be  incurred  by the a 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.


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 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.

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

  In the case of the estate --

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

     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.

     Growth Opportunities Fund. The stock market rebounded sharply in the fourth
     quarter,  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.  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.

     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 the portfolio 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.  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

     A shares,  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 6/3/92.

                               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.

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.

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.


                                       10


<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
earlier  than  those  fixed  for other  types of  options  and may occur  before
definitive closing index values are announced.

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 each Fund to its
   outside  directors/trustees may be 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

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 each Fund have been
associated  with Lord  Abbett for over five  years.  Of the  following,  Messrs.

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  $725,446, $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.

$321,279 and $88,234, respectively.

For the fiscal years ended  November 30, 1999,  1998,  and 1997,  the  Small-Cap

                             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.

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.

                                 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.
